0 | Networking and Timing issue I have been trying to use the low level API for UNET and the focus of this problem is this NetworkEventType recData NetworkTransport.Receive(out recHostId, out connectionId, out channelId, recBuffer, bufferSize, out dataSize, out error) This line is supposed to take in information from many different clients and sits within Update() function. I haven't actually started coding anything in yet... But the point is, if the clients are all transmitting data to the server at a rate equivalent to Update() then this line of code will not be able to (I think?) receive all of them at once (10 clients vs 1 server). So is there a way to not lose any of the incoming data and process them accordingly? |
0 | Improving the look of a character with solid parts inside a translucent jello exterior So my problem is a bit hard to explain. I have a character made out of a jello shell, with an internal skeleton. So let me introduce you to ma boi quot Chonker McJello quot The problem is, that I want a rich green slightly transparent jello, without loosing too much details and quot whiteness quot on the internal skeleton. If I turn the transparency or saturation of the jello down, the jello looks ugly, if I put the jello as I want, the Skeleton looses too much details turns green. I have thought of different approaches, but do not really know how to achieve the effect I want. Single sided emission Is there a way to make the jello glow internally and light the skeleton up? The emission should only come from the backfaces. Doing something with the render layers, like rendering the skeleton with transparency on top of the jello again, to make it appear quot less affected quot by it's color Everything I have in mind sounds easy but is propably pretty complicated and I don't have a lot of experience with shadergraphs and unity's hdrp. If you have any idea how to achieve the desired effect (maybe not in the way I thought) I would really appreciate your help! Thanks a lot! |
0 | How to make colliders for a darts board in Unity? I was wondering how to make a darts board in Unity? Of course it doesn't make triangular objects, or non symmetrical boxes as far as I know, so I would make the board mesh in Blender or something like this. But how would I be able to detect where a dart had hit the certain area? Until now I have only used box, sphere and capsule colliders |

0 | How to create reel slider with mobile controls How can I create a reel slider with mobile game controls so that it looks something like this? The slider is normally non visible, and can be accessed if I slide my finger from the right side of the screen to the left. The slider allows me to switch my current weapon and use items in my inventory. This is my current setup in Unity. I can figure out the inventory portion of the slider, as there are many tutorials out there on an inventory system, and how to make the slider move based on touch, using something similar to a mobile joystick script, but I can't figure out how to make the slider so that it Can quot jump quot from icon to icon (not have the slider be completely fluid prevent it from stopping in between item icons) Detect what item slot the slider is currently on (in the case of the example, the item that will be used is the icon in the center of the screen. Make the icons more transparent the further away it is from the icon in use (I'm guessing that I would have to set the alpha channel value in the color settings of the item to a lower value, but I'm not sure how to detect the icon in use and count how many icons away the other icons are from the one in use. |
0 | Placing units on isometric map (2D) I'm making a map editor for further RTS game (2D), something like the first StarCraft Editor. Terrain tiles will be a rhombuses. So I'll probably just make an 2D array with intigers, that corresponds proper tiles. Then, after creating the terrain, you'd probably like to add some units and structures to map (especially if you're making a scenario). I'm not sure how do I check if the unit can be placed somewhere. I decided to make units almost independent from terrain tiles like in StarCraft (1), so the units are not placed in any grid. I'll give a simple image As you can see, those green tiles represent a passable area (grass, let's say), and a blue one impassable (for example water). That stickman in a box is our unit. You can place it only in green area. That means the box can't go outside the green rhombuses. I have some ideas how to achieve this, but I'm not sure which one would be the most optimal. 1) Since I work in Unity, I could add a collider to every tile. That will be very simple to do and will probably have terrible optimalisation in maps 256x256. 2) Math. I can calculate if any of those boxes crosses tile's borders. If so, I'll have to check if all those tiles are passable. It won't be that easy to programme (well, for me at least) and... yeah, here comes my dillema. Am I right that it would have much better optimalisation? Is it worth the effort? What about saving this map? I can easily save the array with tiles, but how can I do it with units? Just save their positions or is there a better way to do it? EDIT I've tested the first idea (I've written script to create 256x256 map that will be probably the biggest, and to move a camera). The map generates quite long (comparing to tiles without collider), but after that there isn't much difference in performance (it doesn't mean it won't cause problems when I add more features than moving a camera )). I can also attach colliders only to impassable tiles, not all. This should improve the performance even more. Still not sure if that's a good idea. EDIT 2 I've just realised how bad my idea was. Let me visualise this So if you consider not the whole rectangle, but only a circle, it's not only easier to implement, but also more reasonable. You can now convert rhombus' vertices' position from isometric to cartesian like B lint said CartX ( 2 IsoY IsoX) 2 CartY ( 2 IsoY IsoX) 2 You can also do it with circle's center point. Radius is equal to half of square (rhombus) side length OR sqrt(2) square side length (when square is inscribed in circle). So now I have a square grid and a circle. How can I check if all squares that this circle lays on are passable? What's the most optimal way to do it? |
0 | Applying movement to a Rigid Body Isometric in Unity 3D I'm making an isometric dungeon crawler. I initially used transform to get isometric movement and things worked well, but I couldn't use collision which meant it was unsuitable.

Second, how do I get the movement to work in all directions? Current when I move left and right the movement is good, but up and down are really slow in comparison. |

0 | Working with Blender (Model individual objects or scenes?) I've been working in Unity for awhile but I'm pretty new to making my own models. I'm using Blender since it seems like a pretty good tool for the job. Let's say I am making a simple scene in Unity with a table that has a cup and plate on it and some chairs. Assume I want to be able to move each of these objects around independently from the other objects. Does this mean that when modeling in Blender, I have to model each object individually and import them separately in Unity? It would be nice sometimes to be able to model entire scenes in Blender, but if stuff in the scene isn't intended to be static, then there is no way to treat parts of these scene as objects and manipulate them individually in Unity right? |
0 | Trees swaying in the wind using Tilemap I am working on a top down, tile based game (think 2D RPG). However, I would like to have trees that sway in the wind and shake a little if the player bumps into them! How should I approach this? Is it achievable with trees that are composed of tiles and part of a tilemap? Or should I exclude my trees from the tilemap and turn them into game objects instead? If I were to turn them into separate game objects, would I then manually tweak their rotation position to achieve the sway and shake, or is there some form of shader I can use? |

0 | Unity procedural smooth normals I have a Unity project, which heavily relies on the marching cubes algorithm. Because this algorithm doesn't return the triangles in order, I can only index them in the order they are present in the vertices array. For example vertices Vector3(0, 0, 0), Vector3(1, 0, 1), Vector3(1, 1, 0)... triangles 0, 1, 2, 3... Because of this, Unity's RecalculateNormals method doesn't work properly and it gives me the following result Is there anyway I can make the normals smoother? Keep in mind, that I need to possibly recalculate these vertices everytime the values change, so I can't rely on very heavy methods. |

0 | Animation doesn't play in one state I have created an Animator and two sprite based Animations. Both Animations preview correctly. In the Animator, I have created two states and two transitions between them based on a Boolean parameter. In the GameObject's script, the Boolean value is set based on distance to the player. When the player is far away Animation A plays and when the player is close Animation B plays. However, while the transition from Animation A to B happens correctly when the player gets close, I only see the first frame of Animation B and it doesn't animate. If while in Play mode I preview Animation B (using the Animation window controls), it animates correctly. Meanwhile, Animation A always plays correctly when it is supposed to. What could cause this behavior? How can I get Animation B to play during runtime and not just when previewing? What's going on?

0 | Unity Light Baking for Best Balance between Performance and Visuals I'm trying to optimize my Unity game. I have static objects, dynamic objects and (only) static lights. I wish to fully pre compute lighting and shadows for the static objects while still maintaining realtime lighting and shadows for dynamic objects, and making them work together seamlessly. From the documentation Realtime "Unity calculates and updates the lighting of Realtime Lights every frame during run time. No Realtime Lights are precomputed." So, If I set it to realtime, I'm not really optimizing anything, am I? Mixed "Unity can calculate some properties of Mixed Lights during run time, but only within strong limitations. Some Mixed Lights are precomputed." It's unclear what "some properties" are and what would the consequences be. Baked "Unity pre calculates the illumination from Baked Lights before run time, and does not include them in any run time lighting calculations. All Baked Lights are precomputed." This will work for static objects. However, dynamic objects will look as if there are no lights in the scene. From what I see, Mixed would be what I need, but I would still have to adjust its sub modes in the Lighting window which is non trivial for me Subtractive Its description suggests it would solve all my problems and still be a nice optimization. However, static objects don't seem to receive dynamic objects' shadows or the other way around either. Baked Indirect, or Shadowmask Does not seem to pre compute direct lighting for static objects, throwing away performance gains. The final question is what method will lead me to the best performance in Unity with these requirements There are static and dynamic objects that both need to be lit by direct lighting Both static and dynamic objects should be able to cast and receive shadows from each other All lights are static Indirect lighting is not important in this case |

0 | Weird windowed resolution can't seem to change without changing the name My game is windowed, and when I set the resolution in the build settings (960x540 16 9 Windows standalone), and build it, it works as intended, but from then on, I can no longer change the resolution (can change it in the editor, and it also saves, but when I build it, it is still the original res (960x540))unless I change the Product Name as well. When I change the product name, I can change the resolution, build it, and it will change, but then it is stuck as well. When I change back to the first name, the resolution automatically change it the resolution for the first name (960x540) (it doesn't show up in the editor, only when you build it.) So basically Name1 960x540 Name2 1280x720 Name3 1024x576 etc So you can change the resolution every time you change the name and build it, and that name is stuck with that resolution (no matter what you change it to in the editor later).

However, things get interesting when I wish to use this for a bit more complex animations, or I want it to stop upon restart. More complex animations I click a button which then moves to the side and bounches back. For this I need to know when the exact same method finished moving the button so I can restart it to bounce back. Stop upon restart Say I hover my mouse over a button which moves then. However, if it's still moving, I want its current animation to stop, and a new one to start. For both of these I need to know which function affects which GameObject so I can manage that. Question is, how? Shall I use one script on each of the animated components which affects only that one? Or if I could use only one script on the whole Canvas, then how? |

0 | Need help with using Player Prefs to save number of coins collected I'm using unity 3D to make a game where the character collides with coins in order to collect them. When playing the game, the player should start out with zero coins and each time he collides with a coin, the amount should increase by one. On a main menu scene, the total number of coins (that have been collected across multiple games) should be displayed. The total number of coins is being displayed on the main menu but once in the gameplay scene, the total number of coins is being displayed there too (where it's supposed to start at 0 and then increase by 1 each time a coin is collected). Here is the script I use for when the player collides with a coin using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.UI public class CoinScript MonoBehaviour void OnTriggerEnter(Collider target) CoinScoreManager.coinAmount 1 Destroy(gameObject) Here is the script I use to manage the UI and coin number in the game play scene using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.UI public class CoinScoreManager MonoBehaviour public static int coinAmount public Text coinText void Start() coinAmount PlayerPrefs.GetInt( quot CoinAmount quot ) void Update() coinText.text coinAmount.ToString() PlayerPrefs.SetInt( quot CoinAmount quot , coinAmount) Here is the script I use to manage the UI and total coin number in the scene with the main menu using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.UI public class MainMenuController MonoBehaviour int coinAmount public Text coinAmountText void Start() coinAmount PlayerPrefs.GetInt( quot CoinAmount quot ) void Update() coinAmountText.text coinAmount.ToString() I think the problem is in the second script shown above.

0 | C (Unity) Use a method common to multiple classes with the same base class The Problem I'm building one of those empire kingdom building games and so I am trying to create an efficient way of making a "ResourceManager" class handle the games resources (wood, food, iron, stone). I currently repeat a function 4 times to do the same thing. Attempt 1 I created a "Resource" class (abstract) and derived the four resources from it. In each resource there are multiple methods which are similar Example Food.CS new public static void AddResources(int amount) Player.currentFoodSupply amount foodText.text Player.currentFoodSupply.ToString() Compare to Iron.CS new public static void AddResources(int amount) Player.currentIronSupply amount ironText.text Player.currentIronSupply.ToString() The AddResource() function is static because I have other scripts (like buildings, when they get upgraded) needing to communicate with each resource. The base building class currently has a method like this public void DeductResources() Food.DeductResources(FoodCost) Wood.DeductResources(WoodCost) Iron.DeductResources(IronCost) Stone.DeductResources(StoneCost) This seems like it's so repetitive that there needs to be a more efficient way to do this. Attempt 2 A "ResourceManager" class that anything to do with the 4 resources can go through this one script. I can update that one script instead of numerous scripts that does something with the resources. Where I am undecided is this one public static void DeductResources(Resource resource, int amount) if(resource.GetType() typeof(Food)) Player.currentFoodSupply amount resource.resourceText.text Player.currentFoodSupply.ToString() else if (resource.GetType() typeof(Wood)) Player.currentWoodSupply amount resource.resourceText.text Player.currentWoodSupply.ToString() else if (resource.GetType() typeof(Iron)) Player.currentIronSupply amount resource.resourceText.text Player.currentIronSupply.ToString() else if (resource.GetType() typeof(Stone)) Player.currentStoneSupply amount resource.resourceText.text Player.currentStoneSupply.ToString() It looks like it works and I can't see a way around calling the above method 4 times as I need to know how much food or wood to add or deduct. Does anyone have any suggestions please on how to improve this code call the method once? I'm always willing to learn! Thank you |

0 | How to prevent a cube from falling through a plane in Unity I am trying to prevent a player cube from falling through the plane (Battleground) in Unity, but after adding Mesh collider to both the cube and plane, as well as adding a rigidbody, nothing seems to work. The only way I can prevent this from happening is by locking the y axis of the cube, but this is a problem because I am adding in a jumping ability, and the player needs to be able to fall of the map. Is this something I can do within the Unity editor, or do I need to make a script that does that. To verify, all 3 colliders have "Is Trigger" Enabled, the platform is not designed to be moved, so the X, Y and Z of both the plan's rotation and position are locked, and the material for the colliders are all default. Each of the cubes and the plane's material are custom (Not the collider's material). The X, Y and Z of the cube's rotation are locked. Both cubes have the tag 'player' The code for player movement is using System.Collections using System.Collections.Generic using UnityEngine public class PlayerMove MonoBehaviour private Rigidbody rb Use this for initialization void Start() rb GetComponent lt Rigidbody gt () Update is called once per frame void FixedUpdate() float h Input.GetAxis("Horizontal") 5 float v Input.GetAxis("Vertical") 5 Vector3 vel rb.velocity vel.x h vel.z v rb.velocity vel |
0 | Are there performance benefits to using WaitForSeconds vs checking elapsed time in FixedUpdate in Unity? I was considering that perhaps just checking the time and then doing some work in the Update function might look cleaner than calculating how long to wait for and calling yield new WaitForSeconds() on two interleaving processes, so I became curious whether there is a huge difference between the two options. Doesn't WaitForSeconds just work by calling an iterator after a certain amount of time has elapsed? So I assume that a timer is checked on each update, and when the time has elapsed, the IEnumerator's movenext function is called.

0 | Setting up a shader for RTS construction grid visibility (around cursor) I've set up a shader, thanks to the good help of DMGregory over at Draw animating grid with terrain deformation and variable colors here's what I got so far here's what it's supposed to look like here's what my shader code looks like as it stands forgive my non 2K screen it's only a 1080p but this is the full shader. here's each bit in isolation here's the main options for the node If I set surface to transparent... I get a much better result yet still not what I want because the grid area fades out immediately instead of staying at the center of the cube also the corner clearly has a green and red line overlap when line should only ever be red or green. this is the mock file that I'm currently using for buildable and non buildable area it's 256x256 (the size of my map) for now because I want to start small (where 1px maps to one unity square on the terrain of 1 unit) before I move on to the real deal which should be a 3584x3584 Texture 2D (where 1px corresponds to 1 14th of a unity unit). I want my grid to be 1 14th of an digit. eg cell one is (in diagonal) from (0.0f, 0.0f) to (0.14f, 0.14f). I've got preliminary code which will serve to generate this texture 2D programmatically editable2DconstructibleMap new Texture2D(256, 256, TextureFormat.RGBA32, false) constructionGrid GameObject.FindGameObjectWithTag( quot GridViewer quot ).GetComponent lt MeshRenderer gt () fill texture color corresponding to navMesh for (int x 0 x lt editable2DconstructibleMap.width x ) for (int y 0 y lt editable2DconstructibleMap.height y ) NavMeshHit hit if (NavMesh.SamplePosition(new Vector3(x 1.0f, 0f,y 1.0f), out hit, 1.0f, NavMesh.AllAreas)) editable2DconstructibleMap.SetPixel(x, y, Color.white) else editable2DconstructibleMap.SetPixel(x, y, Color.black) constructionGrid.sharedMaterial.SetTexture( quot BuildableMask quot , editable2DconstructibleMap) Here I'm using the navMesh which itself is automatically generated based on terrain slope. I target each point of the map and see if it falls in or out of the navmesh. Instead of redrawing this texture 2D when a building is placed and placement becomes impossible. I think I'll simply programmatically edit the 2D texture to add the new black pixels whilst the navmesh will be updated independently. Anyways, I guess the green red overlap issue comes from my texture2D being currently too small, but if I don't know yet what one pixel corresponds to, I'll have trouble getting this right. Update so changing the texture to one of 3584x3584 did not help. I still have the exact same behavior. So basically what did I get wrong in following the instructions from the other answer? |

0 | Unity2D jumping inconsistancy I'm tinkering with a unity2D sidescroller, and am trying to make a player controller to jump.

There is no consistency to when it occurs, but it has occurred any time between two in a row and 10 12 between times it happens. I have tried long versus short presses of the jump key (space bar), moving versus standing still, and jumping on different locations. I have also tried disabling animations and waiting between presses versus pressing and holding space, versus pressing space rapidly. The only consistent thing is that sometimes I jump about three blocks (200 x 200px each) high, and sometimes I jump about six blocks high. Any tips are appreciated. Thanks! |

0 | Is there a difference between using one large mesh with 100k polygons and using 1000 meshes with 100 polygons each? I'm planning on creating a first person shooter for mobile. Now I know that fps games usually have a lot of meshes in the scene (trees, buildings, terrains, etc.). So I've been looking at a lot of Unity optimization tips. One thing I've noticed is that they always say "If you have a lot of objects in your scene, then each mesh must have low polygon count". But how exactly does this help? If I have a lot of houses in my scene and I ensure that each house has very few polygons, wouldn't the total number of polygons in my scene be affecting the performance anyways? Or will my scene be rendered differently now that I've broken up the total polygon count into multiple parts? |
0 | How can I scale my UI elements to the lesser screen dimension in Unity 5? I want to create a custom mobile pad for my game. The mobile pad consists of two parts (both inside an ui canvas) The D Pad, which will be anchored to the bottom left side. The button group will be anchored to the bottom right side. I would like to resize the element on different resolutions, so that the element (in my case, the D Pad is an image) Has a size of 20 of the minimum of the width and the height. Has pivot of x 0.5, y 0.5. Having anchor of left bottom, its coordinates are (15 , 15 ) wrt the minimum of the width and the height. What I tried is to use an Aspect Ratio Filter in the D Pad image with ratio 1, but it did not work as intended (the coordinates led the image to an unexpected place). Note I am a n00b to Unity. I don't know whether it is right but my Canvas Scaler scales by Constant Pixel Size These images should illustrate what I want to achieve What should I do to make it work like in the pictures?

0 | Scaling HUD and Camera I wanted to display an HUD, similar to the strategic games' one (like in DotA 2, Warcraft III, Starcraft II or Age of Empires). I didn't really know how to do it, so I managed to create a Texture Object and placed it in front of the scene. The image attached is the HUD itself, with some transparent "holes" in which I placed the cameras. I don't know if this description explains well what I'm trying to say, so I made this screenshot The HUD is just a png image with a greater z index. The image has three "holes" one for the gameboard, one for the dice, and one for the spells you can see on the right. The holes are filled with the cameras, so we can see the objects beyond the transparency. Everything looks quite nice. But if I change aspect ratio (which was Free Aspect), my layout gets completely screwed up. Notice that the HUD borders are not fully displayed the spells on the right are misplaced, and so are the dice. I managed to get the free aspect resolution, it is 1440x720, a perfect 2 1. But, even if I change my resolution to 800x400, things are not getting better. I've read something about pillarboxing and letterboxing, but I'm not sure that those techniques will help me with this issue. Is there something I can do to resize my objects and my cameras dynamically to fit the screen for every resolution like in the first screenshot? Of course, if you have any other solutions for the HUD, I'll be glad to learn! |
0 | Simulate wind in a powder game I would like to create a game similar to powder game. I've got a 2d array that stores different types of powder such as sand, water, gas, and fire. I've managed to get these to all move around successfully. I would now like the powders to react to wind. For example if there is fire it should push air upwards. If the air is moving upwards it will move other bits of powder around. The way I've been trying is to have two more 2d byte arrays. One for the wind x direction and another for the wind y direction. The fire will then add an amount to the cells and each update will add the wind x and y to the piece of powder that is on that cell. This almost works but pushes the powder much to fast. The difficulty in doing this is that the powder is on a grid while the wind could be going a variety of directions. What is the most efficient way of doing this? |

0 | Best Practices for Locating Clicks I am building a 2D board game in Unity with a static camera pointed down at the game board. During the active phase of each player's turn, I want to detect where they click on the board. Fortunately, the board is laid out in an easy rectangular grid. (Essentially a trio of 5x5 grids). Which of the following would be best practice to implement this? Create invisible colliders for every square on the board and create a translation function that translates those back to board positions (5,3) with Raytracing? Get the translated coordinates of the click and use a function to figure out which square (if any) the click is in using the mouseclick event handler (by calculating which square the grid coordinates fall in)? Make each square a button with its grid identity encoded and use that in its OnPressed function? Edit 4) Some other idea I haven't thought of yet? Experience level I'm just learning Unity, but have written a lot of C (and tons of other code). |

0 | How can I create a walking zone logic for my player? First I will show a screenshot and explain the logic I think of and what I'm trying to do In the diagram the circle is the player the big rectangle is the zone area for increase decrease speed movement of the player and the small black rectangle is the target. What I'm trying to do is to add some rules for this case. I'm controlling the player in third person movement with the keys WSAD and the mouse to rotate around looking around. This is the player structure screenshot in the Hierarchy There are few rules I'm trying to set for the player in this specific situation in the game and I want to make it generic so I can add the rules or create this behaviour in any place in the game when I need to. The idea is when the player is getting inside the green zone rectangle facing the target make the player slow down to stop smooth. The green zone is the distance from the target to start slow down only if the player is facing the target. If I rotate the player back facing away from the target in the green zone at any time increase the player speed back to normal speed. The idea is that if in the green zone I rotate the player at any time and move hi he will decrease increase the movement speed. Facing target decrease slowly to stop facing away from target increase the speed slowly to normal. |

The reason I'm doing this is because I want consistent 'framerate' by passing that deltaTime parameter Which is for example 0.01f And each step of that loop I'm taking snapshots on multiple cameras with calling Render() method on them before taking a picture. The movement works fine and I see it on snapshots, but some objects has an animation which should also be updated procedurally. I've tried to do animator.speed 0 and then in the same loop, to test it for (int i 1 i lt 1000 i) ... animator.Play("WalkFWD", 0, i 1000f) for example But animation does not change over that loop. It only works with that Play method when I either make this Simulation() method a coroutine and pass one frame (yield return null), or if I use in Update(). So, my question is it possible to procedurally update redraw animation after normalized time of that animation is set. (without waiting for another frame) |

0 | How to write on a Tilemap using a C script? I loaded my tileset asset TileSheet.png using the Tile Palette (Window gt 2D gt Tile Palette). This created the folder "grass tiles" with multiple asset files, one named "TileSheet 168.asset". My goal is to write a script that randomly generates grass tiles within my 128 x 128 tile map. I envision the code looking something like this tilemap.SetTile(new Vector3Int(x, y, 0), "TileSheet " TileNum ".asset) ...where TileNum is a randomly generated integer between 1 and 750 (assuming that's what SetTile even does). Current code using System.Collections using System.Collections.Generic using UnityEngine using UnityEngine.Tilemaps public class drawMap MonoBehaviour public Tile grassTile public Tilemap ChessMap Start is called before the first frame update void Start() RenderMap(GenerateArray(128, 128), ChessMap, grassTile) public static int , GenerateArray(int width, int height) int colorControl 0 int cellFig 0 int , map new int width, height for (int x 1 x lt map.GetUpperBound(0) x ) cellFig x 16 if (Mathf.Floor(cellFig) cellFig) if (colorControl 0) colorControl 1 else colorControl 0 for (int y 1 y lt map.GetUpperBound(1) y ) if (colorControl 0) map x, y 0 else map x, y 1 Debug.Log("Map Coordinates x " x) Debug.Log("Map Coordinates y " y) Debug.Log("color " colorControl) if (colorControl 0) colorControl 1 else colorControl 0 return map public static void RenderMap(int , map, Tilemap tilemap, TileBase tile) Clear the map (ensures we dont overlap) tilemap.ClearAllTiles() Loop through the width of the map for (int x 0 x lt map.GetUpperBound(0) x ) Loop through the height of the map for (int y 0 y lt map.GetUpperBound(1) y ) 1 tile, 0 no tile if (map x, y 1) tilemap.SetTile(new Vector3Int(x, y, 0), "TileSheet " TileNum ".asset) Where I need help is the loading of the asset, referencing the asset, and setting of the asset. I only need this script once, because after it's done, hopefully the GameObject can remember (as if I used the Tile Palette tool). |
0 | Prevent player from jumping on a mesh I am working on a game and I have a mesh that I use to block hallways and prevent the player from going that direction. They are placed vertically with slight angles. I'm having a problem that the player can jump up on these. The player needs to be on the ground all the time otherwise they will be able to avoid dying indefinitely. I have tried moving and rotating and no matter how its placed I can always seem to jump on it. I want to avoid adding more to the scene then what is necessary so I don't want to add another mesh or extra collision of some kind just to keep the player away from those points as that mesh already has collision. Unless it turns out that is actually a good way to handle this. Is there a way I can prevent the player from jumping on these items? Or is there some other way I can handle if the player does jump up on them. Like maybe start damaging the player after a few seconds until they get down? What is a proper way of handling this? |
0 | Player disappears when it collides with a tagged object I am working on a simple game where the goal is to help a Player catch specific objects with a tag "Present". After taking care of the models, animations I am now working on the collisions and counting UI. For the collisions, on my Player Controller (I am using the ThridPersonUserController from the player Unity Standard Assets which simplified the whole animation process), I added the following functions void OnCollisionEnter(Collision other) if (other.gameObject.tag "Present") Destroy(gameObject) count count 1 SetCountText() void SetCountText() countText.text "Count " count.ToString() if (count 0) winText.text "Thanks to you the Christmas will be memorable!" However, like this, when the Player hits an object with the tag "Present", even though the counting is working properly, the player disappears. I have tried to change the OnCollisionEnter to an OnTriggerEnter, like this void OnTriggerEnter(Collider other) if (other.gameObject.CompareTag("Present")) Destroy(gameObject) count count 1 SetCountText() However when the Player hits the objects with the tag "Present", they don't disappear. My Player has a Capsule Collider and a Rigidbody. The objects with the tag "Present" have a Box Collider and a Rigidbody. Any guidance on how to make my Player stay in scene while removing the other objetcs and reducing the count is appreciated. |
0 | Assets bundles have higher size than uncompressed sprites I've created a script that generates assets bundles by compressing sprites using LZ4 compression. I need this in order to generate smaller files that I'll download from a server at runtime but after taking a look at those bundles. I've found out that they actually have a higher size than the uncompressed sprites. For example, I've generated a bundle from three sprites that have a size of 201KB together, but if I take a look at its generated bundle, its size is 300KB. This is only one example, there are other bundles that are 6MB but their original files are only 500KB and that doesn't make any sense to me. Can someone point me in the right direction? |

0 | Need help understanding this script I found this script on a tutorial that I want to implement into my game, but I first want to understand what it does and how it does it. The script is attached to a Joystick UI, which has the inner ring button of the joystick as its child. The script makes the inner button of the joystick move within a certain confine, when the player uses the joystick. quot joystickButton quot is the child object. public class Joystick MonoBehaviour, IDragHandler, IPointerUpHandler, IPointerDownHandler public Image joystickButton public Vector3 inputDirection void Start() inputDirection Vector3.zero public void OnDrag(PointerEventData drag) Vector2 position Vector2.zero RectTransformUtility.ScreenPointToLocalPointInRectangle (joystickButton.rectTransform, drag.position, drag.pressEventCamera, out position) position.x (position.x joystickButton.rectTransform.sizeDelta.x) position.y (position.y joystickButton.rectTransform.sizeDelta.y) float x position.x 2 float y position.y 2 inputDirection new Vector3(x, y, 0) inputDirection (inputDirection.magnitude gt 1) ? inputDirection.normalized inputDirection joystickButton.rectTransform.anchoredPosition new Vector3(inputDirection.x (joystickButton.rectTransform.sizeDelta.x 3), inputDirection.y (joystickButton.rectTransform.sizeDelta.y) 3) public void OnPointerDown(PointerEventData drag) OnDrag(drag) public void OnPointerUp(PointerEventData release) inputDirection Vector3.zero joystickButton.rectTransform.anchoredPosition Vector3.zero I did some research and some tests, and from what I understand, if I tap a point within the Joystick UI's RectTransform, the point I tap, quot drag quot , gets converted to a position in the RectTransform of joystickButton. The position is then converted to a vector, inputDirection, which represents the direction and location of my tap. The vector is then normalized, and the joystickButton is moved to (inputDirection.x (joystickButton.rectTransform.sizeDelta.x 3), inputDirection.y (joystickButton.rectTransform.sizeDelta.y) 3), where the vector is pointing to the direction of my tap, and has a magnitude that is 1 3 the length of the side of joystickButton's RectTransform, since all the anchors are centered, and the RectTransform is a square. What I don't get is why I need these lines RectTransformUtility.ScreenPointToLocalPointInRectangle (joystickButton.rectTransform, drag.position, drag.pressEventCamera, out position) and float x position.x 2 float y position.y 2 Is there any purpose to these lines? Converting the 1st one to position drag.position and the 2nd one to float x position.x float y position.y doesn't seem to mess anything up. Also, I didn't notice at first, but not dividing on by sizeDelta on these lines position.x (position.x joystickButton.rectTransform.sizeDelta.x) position.y (position.y joystickButton.rectTransform.sizeDelta.y) does change the result slightly, so if anyone can tell me what function dividing the values does, it would be greatly appreciated. |
0 | Pausing game with State machine and handling jumps I am adding pause functionality to my upcoming racing game.The players can jump in it. Time.timeScale 0 is obvious solution to pause game.I am avoiding this solution as users can do in app purchases in pause menu and with timeScale to 0 its somehow preventing them. So to overcome that problem I have added state machine pattern to start,pause,resume,finish game. The thing is when I pause game with my state machine pause behaviour it pauses the game properly without any hesitation until the player is Jumping and pause occurs. When player is jumping everything gets pause perfectly,just player falls to ground. So to overcome that problem what I tried was if user pauses game and player is on air the isKinematic on player gets set to to true and game gets pause with player halt on air. The problem with this approach was that when user resume the game ,unexpected jump movement happens, i.e., player does not land on expected position . Example if player on y 10 and game gets pause, with Time.timeScale player will always land on Z 17 ,but with my this second approach player sometimes land on Z 20 ,Z 21 Z 19 etc so my question is how will I do properly pause game with state machine without causing unexpected jump movement. |

0 | Is it possible to render project flatten a 3d model onto a 2d plane in Unity? If I have a 3d Object (character) could I use a renderer shader camera mode to essentially render the 3d object as a 2d sprite? Not looking for a full tutorial on this one, I realize its a large question just looking for a direction to head in. My thought on this one is that it would be easier to create a 3d model and move it to a position for a book style game. The character could be posed in a number of different positions. I'd add some sort of outline and Cel shader and outline to get the affect, but in order to get it to view properly on my otherwise 2d game, I would need it to be in a panel or something that could have a quot Sorting Layer quot added to it. |

0 | Unity or Monogame or Gamemaker 2 for an experienced application developer? So i know this question has been hammered down several times but please bear with me. I used to be a C .Net application developer but i am no longer employed, i am pretty good at C . I want to get into serious game development and i dunno where to start, i used to work with unity occasionally which is a very little and i kinda find it clunky, like it works but somehow it does not feel right and feels kinda clunky. But it works with tiled map editor without much of a hassle. I Remember using Game maker studio when i was back in college and i found it very good, its a breeze to work with and even have its own tiled map editor, even seems to have some good tutorials, the only con is its price. I was initially inclined towards Monogame cause of my C background, but i neither have time nor money and resources to support me for long enough time to be able to code every single thing from scratch and i am kinda in a pretty bad situation overall right now. It just takes too much time to do anything even to make it work with a tiled map editor, and there are very few tutorials or documentation to start with. It seems like the only option for me is Unity at the moment, cause of ease of access and how easy it is to work with tiled map editor and lots of tutorials. which one do you guys think is good overall? Please keep in mind that i am currently unemployed and have very little resources to support myself, and i am a programmer so i don't even know how to compose music and do art for the game and i'd prefer if it provides some asserts to be used so i wont waste time in learning stuff when i cannot afford to spend time. I will eventually learn them but not now, its not happening now so i prefer something that comes with some sorta free asserts that can be used (mainly music and art), I mean does it even matter if all i am trying to do is earn a decent minimum living? I just want to make simple 2D NES Snes style games with multiplayer support. Thank you. |

0 | How to differentiate between instantiated objects in Unity? I'm currently trying to solve a way to go about the following problem before I start writing any code (the old fashioned pen and paper way) but I'm not sure how I could achieve the following. I'm going to have an object with a Collider attached to it in my scene. As my instantiated enemies pass through this Collider they will be added to an ArrayList which lets the object in question keep track of the enemies. The problem I can't figure out is how to determine which object is which. I will have a script attached to my main camera which will be responsible for spawning the enemy units, I'll be using a while loop in sudo code it would look something like this. public Transform (Attach the prefab in the inspector) Somefunction() int i 0 arraylist goes here while (i lt 10) arraylist i Newly instantiated object. My object with the collider will then have something like the following OnTriggerEnter() get specific object somehow add to arraylist I can't use the tag function because all the objects will have the same tag, the only thing I assume will be different is the position of the object in the spawn array (ie arraylist 1 arraylist 2 etc.) If I created a public accessor method on the trigger object could I call this method to return a string name or something special that identifies the object uniquely compared to the rest of the objects in the scene or does Unity already do this somehow natively? |

0 | Game launcher updater download delta diff I'm making a launcher for my game (using Unity3d). I want it to have the following features Compare game version to latest version and update if necessary Check files integrity and update if differences are found Download patch needed files So comparing the game version is easy I just parse a version.txt file and compare it's value to the latest server version. Checking file integrity sounds easy too Make a list of all files in the game folder, order the list, get a checksum and check if it corresponds. Now here's the difficult part Downloading the required files. My first idea was If a file checksum is different, download that file. But unity assets are compressed into large files, so even a simple change will lead to the download of a 2gb file... So I'm now looking for a way do download only the different parts. I heard about VCDIFF xdelta, apparently they can be useful to get a "delta patch" of different binaries. Cool. But how can I compare two folders if one of them is distant, without downloading it all before ? Could torrent be an answer ? How are game unity devs doing this ? Maybe rsync can be useful, but is it safe if hundreds of clients are simultaneously updating using rsync ? I heard about Unity's AssetBundles. Is that useful and is it ok to put ALL my assets in bundles ? How would I display a progress bar in unity showing the rsync progression ? |

0 | What method could I use to avoid using a lookup table for each item when loading a players inventory? Let me explain a little about the pickup items and inventory to make this much clearer. Every in world item that can be picked up has a ScriptableObject assigned to it that contains all the information about that item (id, name, description, maxstacksize, sprite etc). When a player picks up an item it gets added to a List lt InventoryItem gt . InventoryItem is a class that gets populated with some of the data pulled from the ScriptableObject (id, name, description, maxstacksize), and also gets an amount property. I want to save the players inventory, but want to simplify the InventoryItem data. So I created an InventoryItemSimple struct that holds the id and amount for each item in the inventory, and then save that list to file. When loading the player inventory, currently I have a BIG list of ScriptableObjects that map to the id. So I am looping over the saved inventory list and matching against the id in the lookup table, and then adding the item to the inventory. I want to avoid this as over time their could be 2,000 unique objects that could be in the world. What's a better method to handle this? If I stick with the lookup table, do I need to worry about how much memory is being used? I don't think my lookup table will ever contain 2,000 elements. But the thought of having one massive list to manage doesn't appeal to me. |
