• How can i get latency when using Game Center?

  - by Freddy

  I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

• Camera Collision inside the room model

  - by sanddy

  I am having a problem in Calculating the camera collision for my Room model which consists of sofa, tables and other models. The users shall be moving the camera front, back, rotating so i need to make sure that the camera does not collide with any of the models with in the room. I have treated all my models inside the room by BoundingBox[] and the camera by BoundingSphere. So, far i have implemented collision by looking into the tutorial from http://www.toymaker.info/Games/XNA/html/xna_model_collisions.html which was great. But, I guess the problem lies in the Transformation part. I debugged and found some points to be at Vector(-XXX,-XXX,-XXX) where X is digit. Also i found my radius of some models where too large(in thousand, i just looked into its radius value before converting to BoundingBox). Do I need to scale the model for collision??? Below are my code:- On My LoadContent(): Matrix[] transforms = new Matrix[myModel.Bones.Count]; myModel.CopyAbsoluteBoneTransformsTo(transforms); int index = 0; box = new List<BoundingBox>(); BoundingBox worldModel = Utility.CalculateBoundingBox(myModel); foreach (ModelMesh mesh in myModel.Meshes) { Vector3[] obb = new Vector3[8]; worldModel.GetCorners(obb); Vector3[] asdf = (Vector3[])obb.Clone(); Vector3.Transform(obb, ref transforms[mesh.ParentBone.Index], obb); BoundingBox worldBox = BoundingBox.CreateFromPoints(obb); box.Add(worldBox); index++; } On CameraPosition Update: BoundingSphere bs = new BoundingSphere(this.cameraPos, 5.0f); if (RoomWalkthrough.Utility.CheckCollision(bs, bb)) { // Do Something } Please Help.

• Changing State in PlayerControler from PlayerInput

  - by Jeremy Talus

  In my player input I wanna change the the "State" of my player controller but I have some trouble to do it my player input is declared like that : class ResistancePlayerInput extends PlayerInput within ResistancePlayerController config(ResistancePlayerInput); and in my playerControler I have that : class ResistancePlayerController extends GamePlayerController; var name PreviousState; DefaultProperties { CameraClass = class 'ResistanceCamera' //Telling the player controller to use your custom camera script InputClass = class'ResistanceGame.ResistancePlayerInput' DefaultFOV = 90.f //Telling the player controller what the default field of view (FOV) should be } simulated event PostBeginPlay() { Super.PostBeginPlay(); } auto state Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 200; `log("Player Walking"); } } state Running extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 350; `log("Player Running"); } } state Sprinting extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 800; `log("Player Sprinting"); } } I have tried to use PCOwner.GotoState(); and ResistancePlayerController(PCOwner).GotoState(); but won't work. I have also tried a simple GotoState, and nothing happen how can I call GotoState for the PC Class from my player input ?

• XNA C# How to draw fonts in different color

  - by XNA newbie

  I'm doing a simple chat system with XNA C#. It is a chatbox that contains 5 lines of chat typed by the users. Something like a MMORPG chatting system. [User1name] says: Hi [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. When the user pressed 'ENTER', the text he entered will be added inside an ArrayList chatList.Add(s); For displaying the text he entered, I used for (int i = 0; i < chatList.Count(); i++) { spriteBatch.DrawString(font, chatList[i], new Vector2(40, arr1[i]), Color.Yellow); } *arr1[i] contains 5 y-axis points to print my 5 line of chats in the chatbox Question1: What if I have another type of message which will be added into ChatList (something like a system message). I need the System Message to be printed out in red color. And if the user keeps on chatting, the chat box will be updated according: (MAX 5 LINES) The newest chat will be shown below, and the oldest one will be deleted if they reached the max 5 lines. [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. [User1name] says: Ok, great to hear that! I'm having trouble to print each line color according to their msg type. For normal msg, it should be yellow. For system msg, it should be red. Question2: And for the next problem, I need the chat texts to be white color, while the names of the user is yellow (like warcraft3 chat system). How do I do that? I have a hard time thinking of a solution for these to work. Advise needed.

• XNA C# Rectangle Intersect Ball on a Square

  - by user2436057

  I made a Game like Peggle Deluxe using C# and XNA for lerning. I have 2 rectangles a ball and a square field. The ball gets shoot out with a cannon and if the Ball hits the Square the Square disapears and the Ball flys away.But the Ball doesent spring of realistically, it sometimes flys away in a different direction or gets stuck on the edge. Thads my Code at the moment: public void Update(Ball b, Deadline dl) { ArrayList listToDelete = new ArrayList(); foreach (Field aField in allFields) { if (aField.square.Intersects(b.ballhere)) { listToDelete.Add(aField); Punkte = Punkte + 100; float distanceX = Math.Abs(b.ballhere.X - aField.square.X); float distanceY = Math.Abs(b.ballhere.Y - aField.square.Y); if (distanceX < distanceY) { b.myMovement.X = -b.myMovement.X; } else { b.myMovement.Y = -b.myMovement.Y; } } } It changes the X or Y axis depending on how the ball hits the Square but not everytimes. What could cause the problem? Thanks for your answer. Greetings from Switzerland.

• 2D Grid based game - how should I draw grid lines?

  - by Adam K Dean

  I'm playing around with a 2D grid based game idea, and I am using sprites for the grid cells. Let's say there is a 10 x 10 grid and each cell is 48x48, which will have sprites drawn there. That is fine. But in design mode, I'd like to have a grid overlay the screen. I can do this either with sprites (2x600 pixel image etc) or with primitives, but which is best? Should I really be switching between sprites and 3d/2d rendering? Like so: Thanks!

• Deferred Shading - Toolkit

  - by AliveDevil

  I recently managed to get some lights rendered in a scene by using a buffer and a for-loop. The problem with this method is the performance drop if more lights are used. I tried to convert Deferred Rendering in XNA4.0 | ROY-T.NL but it is not working, because I am not using any models. I know I have to render color, normals and lights seperate but I don't know how I could get it working. For understanding my structure better I'm using a world-class which holds some chunks. These chunks are loading all vertices from their items. These items have a property which returns the vertices. The item is returning VertexPositionNormalTexture[]. The chunk loads these Vertices and combines them to one large array of VertexPositionNormalTexture via someList.AsParallel().SelectMany(m => m).ToArray()). m is a VertexPositionNormalTexture. someList is List<VertexPositionNormalTexture>. I got my own shader to draw these vertices how I want them to be drawn. The first thing I would try is setting up two RenderTarget2D for rendering the color and normal part. With two different shaders. Than I would have to render the lights and there's the problem: I don't know how. I set up a structure to simplify working with lights but it didn't really help. public struct Light { public Vector3 Position; public Color4 Color; public float Range; public float Intensity; public Light( Vector3 position, Color color, float range, float intensity ) : this() { this.Position = position; this.Color = color; this.Range = range; this.Intensity = intensity; } public float[] Definition { get { return new[] { Position.X, Position.Y, Position.Z, Color.Red, Color.Green, Color.Blue, Intensity, Range }; } } } The next part is equally different because I don't know how to combine the colorMap, normalMap and textureMap to one finalMap. Some information to the system: I'm using SharpDX (Nightly from some months ago) and the SharpDX.Toolkit (I don't want to mess up with Direct3DDevice and similar things). Can someone help me with this problem? If things are missing or I provided insufficient information tell me, I need to get deferred shading working. Things I'm not able to do: create a rendertarget which holds all lights, merge colorMap, normalMap and lightMap to one finalMap and presenting this to the user.

• How to loop section from a song correctly?

  - by Teflo

  I'm programming a little Music Engine for my game in C# and XNA, and one aspect from it is the possibility to loop a section from a song. For example, my song has an intropart, and when the song reached the end ( or any other specific point ), it jumps back where the intropart is just over. ( A - B - B - B ... ) Now I'm using IrrKlank, which is working perfectly, without any gaps, but I have a problem: The point where to jump back is a bit inaccurate. Here's some example code: public bool Passed(float time) { if ( PlayPosition >= time ) return true; return false; } //somewhere else if( song.Passed( 10.0f ) ) song.JumpTo( 5.0f ); Now the problem is, the song passes the 10 seconds, but play a few milliseconds until 10.1f or so, and then jumps to 5 seconds. It's not that dramatic, but very incorrect for my needs. I tried to fix it like that: public bool Passed( float time ) { if( PlayPosition + 3 * dt >= time && PlayPosition <= time ) return true; return false; } ( dt is the delta time, the elapsed time since the last frame ) But I don't think, that's a good solution for that. I hope, you can understand my problem ( and my english, yay /o/ ) and help me :)

• Self learning automated movement

  - by Super1

  I am trying to make a small demo in Javascript, I have a black border and a car the car travels randomly and a line is drawn of its trail. When the user click inside the area it creates an object (we'll call this the wall). If the car hits the wall then it goes back 3 paces and tries a different route. When its hit the wall it needs to log down its location so it does NOT make that mistake again. Here is my example: http://jsfiddle.net/Jtq3E/ How can I get the car to move by itself and create a trail?

• What do you use to bundle / encrypt data?

  - by David McGraw

  More and more games are going the data driven route which means that there needs to be a layer of security around easy manipulation. I've seen it where games completely bundle up their assets (audio, art, data) and I'm wondering how they are managing that? Are there applications / libraries that will bundle and assist you with managing the assets within? If not is there any good resources that you would point to for packing / unpacking / encryption? This specific question revolves around C++, but I would be open to hear how this is managed in C#/XNA as well. Just to be clear -- I'm not out to engineer a solution to prevent hacking. At the fundamental level we're all manipulating 0's and 1's. But, we do want to keep the 99% of people that play the game from simply modifying XML files that are used to build the game world. I've seen plenty of games bundle all of their resources together. I'm simply curious about the methods they're using.

• Blender to 3ds max to cal3d format

  - by Kaliber64

  There are quite a few questions on cal3d but they are old and don't apply anymore. In Blender(must be 2.49a for python script to work!!!): I have a scene with 7 meshes, 1 armature, 10 bones. I tried going to one mesh to simplify it but doesn't change anything. I found a small blend file that was used for cal3d and it exported just fine. So I tried to copy it's setup with no success. EDIT*8/13/2012 In the last week here is what I have found so far. I made the mesh in the newest blender(2.62?) and exported it to import it in the old one(2.49a). Did an animation in the old one because importing new blend files to old blenders, its just said it would lose keyframe data and all was good. And then you get the last problem of it not exporting meshes. BUT I found that meshes made in the old one export regardless. I can't find any that won't export. So if I used the old blender to remake my model I could get it to export :) At this point I found a modified release of cal3d (because the most core model variable would not initiate as I made a really small test subject in old blender instead of remaking my big one which took 4 hours.) which fixes the morph objects and adds what cal3d left off with. Under their license they have to release the modification but it has no documentation so I have to figure it out on my own. Its mostly the same. But with this lib it came with a 3ds max exporter. My question now is how do I transfer armature and mesh information from blender to 3ds max in order to export into cal3d format. Every time I try the models are see through and small and there are no bones. The formats I have tried to import are .3ds .obj(mesh only) and COLLADA. In all of them the mesh is invisible and no bones. It says the default texture is on so I should be able to see it. All the vertices are present I found a vertex highlighter so I can see those. If any of this is confusing let me know so I can clear it up. Its late .<=sleep.

• DX11 - Weird shader behavior with and without branching

  - by Martin Perry

  I have found problem in my shader code, which I dont´t know how to solve. I want to rewrite this code without "ifs" tmp = evaluate and result is 0 or 1 (nothing else) if (tmp == 1) val = X1; if (tmp == 0) val = X2; I rewite it this way, but this piece of code doesn ´t word correctly tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 val = !tmp * X2 However if I change it to: tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 if (!tmp) val = !tmp * X2 It works fine... but it is useless because of "if", which need to be eliminated I honestly don´t understand it Posted Image . I tried compilation with NO and FULL optimalization, result is same

• Isometric projection bad coordonate

  - by Christophe Debove

  I have a 2D map, for each element I apply this isometric projection to place my Sprite //Element e; float[] f= projection(e.getX(), e.getY() ,z); // x and y represent Sprite Coordonate (tile_width and height depend of my // camera size and the number of elements in x and in y float x = f[0]*tile_width; float y = f[1]*tile_height; public float[] projection(float x, float y, float z) { return new float[]{ (( x )-(y) ) , ((x/2) + (y/2) - z )}; } the sprite for one element : The result of my projection : The problem is I need to add an offset of tile_height/2 to the y and tile_width/2 to the x to have something like this (in the red rectangle I drawed with paint what I want) : Where did I make wrong? (I found the projection method in How should I sort images in an isometric game so that they appear in the correct order? )

• How do I prevent other dynamic bodies from affecting the player's velocity with Box2D?

  - by Milo

  I'm working on my player object for my game. PhysicsBodyDef def; def.fixedRotation = true; def.density = 1.0f; def.position = Vec2(200.0f, 200.0f); def.isDynamic = true; def.size = Vec2(50.0f,200.0f); m_player.init(def,&m_physicsEngine.getWorld()); This is how he moves: b2Vec2 vel = getBody()->GetLinearVelocity(); float desiredVel = 0; if (m_keys[ALLEGRO_KEY_A] || m_keys[ALLEGRO_KEY_LEFT]) { desiredVel = -5; } else if (m_keys[ALLEGRO_KEY_D] || m_keys[ALLEGRO_KEY_RIGHT]) { desiredVel = 5; } else { desiredVel = 0; } float velChange = desiredVel - vel.x; float impulse = getBody()->GetMass() * velChange; //disregard time factor getBody()->ApplyLinearImpulse( b2Vec2(impulse,0), getBody()->GetWorldCenter(),true); This creates a few problems. First, to move the player at a constant speed he must be given a high velocity. The problem with this is if he just comes in contact with a small box, he makes it move a lot. Now, I can fix this by lowering his density, but then comes my main issue: I need other objects to be able to run into him, but when they do, he should be like a static wall and not move. I'm not sure how to do that without high density. I cannot use collision groups since I still need him to be solid toward other dynamic things. How can this be done? Essentially, how do I prevent other dynamic bodies from affecting the player's velocity?

• Wheel rotation, to change velocity of vehicle

  - by Lewis

  I update the velocity of my vehicle like so: [v setVelocity: ((2 * 3.14 * 100 * (wheel.getRotationValue / 360) / 30)) * gameSpeed]; // update on 60 fps this gets velocity on all frames divide by 60 for 1 frame. This is done in my update method in my world class. Now wheel.getRotationValue returns the rotation value which is worked out like this: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); float limit = 0.5; rotationValue += (currentTouch - previousTouch) * limit; } touching = YES; } Say I steer the vehicle to the far right of the screen, and want to move it to the far left, It wont start moving to the left of the screen until the rotationValue is past 0 degrees again (the wheel is in its center posistion) and is dragged past this value. Is there anyway to change the code I have above, so that movement on the wheel is recognised instantly and updates the velocity of v instantly too?

• 3D zooming technique to maintain the relative position of an object on screen

  - by stark

  Is it possible to zoom to a certain point on screen by modifying the field of view and rotating the view of the camera as to keep that point/object in the same place on screen while zooming ? Changing the camera position is not allowed. I projected the 3D pos of the object on screen and remembered it. Then on each frame I calculate the direction to it in camera space and then I construct a rotation matrix to align this direction to Z axis (in cam space). After this, I calculate the direction from the camera to the object in world space and transform this vector with the matrix I obtained earlier and then use this final vector as the camera's new direction. And it's actually "kinda working", the problem is that it is more/less off than the camera's rotation before starting to zoom depending on the area you are trying to zoom in (larger error on edges/corners). It looks acceptable, but I'm not settling for only this. Any suggestions/resources for doing this technique perfectly? If some of you want to explain the math in detail, be my guest, I can understand these things well.

• How should I generate and store the boundries of a cave?

  - by Bob Roberts

  I am making a small cave copter game (seriously, where did this type of game come from anyway) and I am trying to figure out how to make and store the procedural generated walls. I am thinking about creating the walls by randomly picking two points away from the center of the screen. They will be no closer than the height of helicopter and no further than the edge of the screen, weighted to prefer to go in the same direction as the point prior so I end up with stalactites and stalagmites and not just noise, at set intervals of distance. To store, perhaps parallel arrays/lists, one for distance from center to top screen and one for distance from center to bottom. Am I way off base with my thinking? I just want the cave to be varied and challenging, I just have never worked with generating data like this. Edit: Woah, I just realized that my idea would lead to a player being able to stay in the middle of the screen and win. That isn't right at all. So the very basis of how I was going to generate is wrong. Edit 2: I also realized I left out a very crucial point. Part of the mechanics of the game will let the player go backwards therefor the data structure should be continuous.

• Can anyone recommend an AI sandbox?

  - by user19433

  I'm passionate person, who has been around AI from a long time [1] but never going in deep enough. Now it's time! I've been really looking for some way to concentrate on AI coding but couldn't succeeded to find an AI environment I can focus on. I just want to use an AI sandbox environment which would let me have tools like: visibility information character controller able to easily define a level, with obstacles of course physics collider management triggers management don't need to be a shiny, eye candy graphical render : this is about pathfinding, tactical reasoning, etc.. I have tried : Unreal Dev Kit : while the new release announce is about C++ coding, this is about external tools and will be released in 2013 Cry Engine : really interesting as AI is presents here but coding with it appears to be an hell: did I got it wrong ? Half Life source, C4, Torque, Dx Studio : either quite old, not very useful or costly these imply to dig in documentation (when provided) to code everything, graphics included. Unity 3D : the most promising platform. While you also need to create your own environment, there are lot of examples. The disadvantage is, in addition to spend time to have this env. working, is the languages choice : C#, Javascript or Boo. C# is not that hard, but this implies you'll allways have to convert papers (I love those from Lars Linden) books codes, or anything you can have in Aigamedev are most often in C++. This is extra work. I've look at "Simple Path", the very good Arong Greenberg work but no source provided and AngryAnt work. AI Sandbox : this seems to be exactly what as AI coder I want to use. I saw some preview but from 2009 we still don't know what it will be about precisely, will it be opensource or free (I strongly doubt), will I be able to buy it? will it really provide me tools I need to focus on AI ? That being said, what is the best environment to be able to focus on AI coding only, is it even possible?

• How to cull liquids

  - by Cyral

  I use culling on my Tiles in my 2D Tile Based Platformer, so only ones needed are drawn on screen. Thats easy to do. However, My Liquid tiles (Water, lava, etc) require an Update Method aswell as the normal Draw, which does checks against tiles, makes it flow, etc. So how should I cull liquid updates in my game? Not culling is to slow, culling only on screen looks awkward when you move. What do you think would be best for the player? Maybe someway of culling the visible tiles PLUS also adding the width/height of the viewport to start culling tiles at a fast enough rate in front of the player so it dosent look awkward when moving? (Not sure how to do this though, something with MaxSpeed of player and width of screen)

• Dynamic audio score/music

  - by Joel Martinez

  I'm interested in developing a game who's background music changes with the mood and scenario of the game's action. Of course many existing games do this (halo for example), but I was interested in any resources/papers/articles talking about the techniques to develop a system like this. I have some ideas, and I understand that this will be equally challenging to implement at the code level as it will be to come up or acquire music that fits this model. Any links or, answers with ideas in them would he appreciated. Edit: this is the kind of info I'm looking for :) http://halo.bungie.org/misc/gdc.2002.music/

• How can I create tiles that scale to multiple resolutions?

  - by Darestium

  I am trying to create a multiplayer version of the popular Flash game N in Java. However, I'm not sure how to create a tileset that will scale up. Are the tiles for N pre-drawn or are they defined with mathamatical formulas in code? I do see how they would scale up in Flash if they were pre-rendered. So if anyone has any ideas how I should go about creating the tileset, or how they are created in the game please let me know. You can check out the game here.

• database design help for game / user levels / progress

  - by sprugman

  Sorry this got long and all prose-y. I'm creating my first truly gamified web app and could use some help thinking about how to structure the data. The Set-up Users need to accomplish tasks in each of several categories before they can move up a level. I've got my Users, Tasks, and Categories tables, and a UserTasks table which joins the three. ("User 3 has added Task 42 in Category 8. Now they've completed it.") That's all fine and working wonderfully. The Challenge I'm not sure of the best way to track the progress in the individual categories toward each level. The "business" rules are: You have to achieve a certain number of points in each category to move up. If you get the number of points needed in Cat 8, but still have other work to do to complete the level, any new Cat 8 points count toward your overall score, but don't "roll over" into the next level. The number of Categories is small (five currently) and unlikely to change often, but by no means absolutely fixed. The number of points needed to level-up will vary per level, probably by a formula, or perhaps a lookup table. So the challenge is to track each user's progress toward the next level in each category. I've thought of a few potential approaches: Possible Solutions Add a column to the users table for each category and reset them all to zero each time a user levels-up. Have a separate UserProgress table with a row for each category for each user and the number of points they have. (Basically a Many-to-Many version of #1.) Add a userLevel column to the UserTasks table and use that to derive their progress with some kind of SUM statement. Their current level will be a simple int in the User table. Pros & Cons (1) seems like by far the most straightforward, but it's also the least flexible. Perhaps I could use a naming convention based on the category ids to help overcome some of that. (With code like "select cats; for each cat, get the value from Users.progress_{cat.id}.") It's also the one where I lose the most data -- I won't know which points counted toward leveling up. I don't have a need in mind for that, so maybe I don't care about that. (2) seems complicated: every time I add or subtract a user or a category, I have to maintain the other table. I foresee synchronization challenges. (3) Is somewhere in between -- cleaner than #2, but less intuitive than #1. In order to find out where a user is, I'd have mildly complex SQL like: SELECT categoryId, SUM(points) from UserTasks WHERE userId={user.id} & countsTowardLevel={user.level} groupBy categoryId Hmm... that doesn't seem so bad. I think I'm talking myself into #3 here, but would love any input, advice or other ideas. P.S. Sorry for the cross-post. I wrote this up on SO and then remembered that there was a game dev-focused one. Curious to see if I get different answers one place than the other....

• Converting a GameObject method call from UnityScript to C#

  Here is the UnityScript implementation of the method i use to generate a randomly tiled background, the problem i'm having relates to how to translate the call to the newTile method in c#, so far i've had no luck fiddling... can anyone point me in the correct direction? Thanks #pragma strict import System.Collections.Generic; var mapSizeX : int; var mapSizeY : int; var xOffset : float; var yOffset : float; var tilePrefab : GameObject; var tilePrefab2 : GameObject; var tiles : List.<Transform> = new List.<Transform>(); function Start () { var i : int = 0; var xIndex : int = 0; var yIndex : int = 0; xOffset = 2.69; yOffset = -1.97; while(yIndex < mapSizeY){ xIndex = 0; while(xIndex < mapSizeX){ var z = Random.Range(0, 5); if (z > 2) { var newTile : GameObject = Instantiate (tilePrefab, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 2) { var newTile2 : GameObject = Instantiate (tilePrefab2, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "Ztile_"+i; i++; xIndex++; } } yIndex++; } } C# Version [Fixed] using UnityEngine; using System.Collections; public class LevelGen : MonoBehaviour { public int mapSizeX; public int mapSizeY; public float xOffset; public float yOffset; public GameObject tilePrefab; public GameObject tilePrefab2; int i; public System.Collections.Generic.List<Transform> tiles = new System.Collections.Generic.List<Transform>(); // Use this for initialization void Start () { int i = 0; int xIndex = 0; int yIndex = 0; xOffset = 1.58f; yOffset = -1.156f; while (yIndex < mapSizeY) { xIndex = 0; while(xIndex < mapSizeX) { int z = Random.Range(0, 5); if (z > 5) { GameObject newTile = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 5) { GameObject newTile2 = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "tile2_"+i; i++; xIndex++; } } yIndex++; } } // Update is called once per frame void Update () { } }
