• Exporting the frames in a Flash CS5.5 animation and possibly creating the spritesheet

  - by Adam Smith

  Some time ago, I asked a question here to know what would be the best way to create animations when making an Android game and I got great answers. I did what people told me there by exporting each frame from a Flash animation manually and creating the spritesheet also manually and it was very tedious. Now, I changed project and this one is going to contain a lot more animations and I feel like there has to be a better way to to export each frame individually and possibly create my spritesheets in an automated manner. My designer is using Flash CS5.5 and I was wondering if all of this was possible, as I can't find an option or code examples on how to save each frame individually. If this is not possible using Flash, please recommend me another program that can be used to create animations without having to create each frame on its own. I'd rather keep Flash as my designer knows how to use it and it's giving great results.

• Admob banner not getting remove from superview

  - by Anil gupta

  I am developing one 2d game using cocos2d framework, in this game i am using admob for advertising, in some classes not in all classes but admob banner is visible in every class and after some time game getting crash also. I am not getting how admob banner is comes in every class in fact i have not declare in Rootviewcontroller class. can any one suggest me how to integrate Admob in cocos2d game, i want Admob banner in particular classes not in every class, I am using latest google admob sdk, my code is below: Thanks in advance ` -(void)AdMob{ NSLog(@"ADMOB"); CGSize winSize = [[CCDirector sharedDirector]winSize]; // Create a view of the standard size at the bottom of the screen. if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(size.width/2-364, size.height - GAD_SIZE_728x90.height, GAD_SIZE_728x90.width, GAD_SIZE_728x90.height)]; } else { // It's an iPhone bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(size.width/2-160, size.height - GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)]; } if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { bannerView_.adUnitID =@"a15062384653c9e"; } else { bannerView_.adUnitID =@"a15062392a0aa0a"; } bannerView_.rootViewController = self; [[[CCDirector sharedDirector]openGLView]addSubview:bannerView_]; [bannerView_ loadRequest:[GADRequest request]]; GADRequest *request = [[GADRequest alloc] init]; request.testing = [NSArray arrayWithObjects: GAD_SIMULATOR_ID, nil]; // Simulator [bannerView_ loadRequest:request]; } //best practice for removing the barnnerView_ -(void)removeSubviews{ NSArray* subviews = [[CCDirector sharedDirector]openGLView].subviews; for (id SUB in subviews){ [(UIView*)SUB removeFromSuperview]; [SUB release]; } NSLog(@"remove from view"); } //this makes the refreshTimer count -(void)targetMethod:(NSTimer *)theTimer{ //INCREASE OF THE TIMER AND SECONDS elapsedTime++; seconds++; //INCREASE OF THE MINUTOS EACH 60 SECONDS if (seconds>=60) { seconds=0; minutes++; [self removeSubviews]; [self AdMob]; } NSLog(@"TIME: %02d:%02d", minutes, seconds); } `

• Camera Projection back Into 3D world, offset error

  - by Anthony

  I'm using XNA to simulate a robot in a 3D world and then do image analysis on what the camera sees. I have my camera looking down in front of the direction that the robot is going, and I have the robot detecting white pixels. I'm trying to take the white pixels that it finds and project them back into the 3D world so that I can see if it is actually detecting the correct pixels. I almost have it working, but there is an offset between where the white is in in the World and were I put my orange triangles (which represent what the robot things is white). /// <summary> /// Takes a bool map of and makes vertex positions based on the map. /// </summary> /// <param name="c"> The bool map</param> private void ProjectBoolMapOnGroundAnthony2(bool[,] c) { float triangleSize = 0.04f; // Point of interest in World W cordinate system.

• Java Slick2d Animation not working

  - by user3558075

  Hello everyone I am trying to make a simple 2d game using java and the slick2d library. this is my first time doing it and i need some help. right now I am trying to make the Animations for the character, so that when you go right he turns right and when you go left he turns left... but I keep getting an error when im drawing the character, ive try'd re-downloading slick but that didnt work. when i get rid of the player.draw(x,y); line of code it dosen't crash but the character isnt there. heres my code, can anyone help? package enteties; import input.Keyinput; import org.newdawn.slick.Animation; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Image; import org.newdawn.slick.Input; import org.newdawn.slick.SlickException; import org.newdawn.slick.state.BasicGameState; import org.newdawn.slick.state.StateBasedGame; import playerinfo.Playerinfo; public class Player extends BasicGameState{ Playerinfo pi = new Playerinfo(); Keyinput ki = new Keyinput(); Animation player,up,down,left,right; public void init(GameContainer gc, StateBasedGame sbg) throws SlickException { Image[] goingUp = {new Image("res/buckysBack.png") , new Image("res/charBack.png")}; Image[] goingDown = {new Image("res/buckysFront.png") , new Image("res/charFront.png")}; Image[] goingLeft = {new Image("res/buckysLeft.png") , new Image("res/charLeft.png")}; Image[] goingRight = {new Image("res/buckysRight.png") , new Image("res/charRight.png")}; int[] duration = {200,200}; Animation up = new Animation(goingUp,duration,false); Animation down = new Animation(goingDown,duration,false); Animation left = new Animation(goingLeft,duration,false); Animation right = new Animation(goingRight,duration,false); player = up; } public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException { //error happens here, when i remove this line it dosent crash player.draw(720,450); } public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException { } public int getID() { return 0; } }

• Slick and Timers?

  - by user3491043

  I'm making a game where I need events to happen in a precise amount of time. Explanation : I want that event A happens at 12000ms, and event B happens every 10000ms. So "if"s should looks like this. //event A if(Ticks == 12000) //do things //even B if(Ticks % 10000 == 0) //do stuff But now how can I have this "Ticks" value ? I tried to declare an int and then increasing it in the update method, I tried 2 ways of increasing it : Ticks++; It doesn't works because the update method is not always called every microseconds. Ticks += delta; It's kinda good but the delta is not always equals to 1, so I can miss the precise values I need in the if statements So if you know how can I do events in a precise amount of time please tell me how can I do this

• Rendering of 2d water

  - by luke

  Suppose you have a nice way to move your 2D particles in order to simulate a fluid (like water). Any ideas on how to render it? Consider the fact that the game is a 2D game. The perspective is like this (the first image i have found): an example of 2d water. The water will be contained in boxes that can be broken in order to let it fall down and interact with other objects. The most simple way that comes to my mind is to use a small image for each particle. I am interested in hearing more ways of rendering water. Thank you.

• As a game developer, which data structure use for develop the game? [duplicate]

  - by Rizwanabbasi

  This question already has an answer here: When should vector/list be used? 5 answers We are developing a game for bank robbery. The game plots a bank robbery. Lots of people witness that robbery. Our game will load the lists of suspected offenders while the players (witnesses) will have to identify the offenders of this robbery. Game should load list of offenders to identify the one as quickly as possible. Admin can add/remove offenders in the lists and two or more lists of offenders can also be merged into one (to show it to the player). As a game developer, which data structure we should use for develop the game? Justify your selection with solid arguments. Remember the most critical requirement is that the list should load super fast.

• Writing the correct value in the depth buffer when using ray-casting

  - by hidayat

  I am doing a ray-casting in a 3d texture until I hit a correct value. I am doing the ray-casting in a cube and the cube corners are already in world coordinates so I don't have to multiply the vertices with the modelviewmatrix to get the correct position. Vertex shader world_coordinate_ = gl_Vertex; Fragment shader vec3 direction = (world_coordinate_.xyz - cameraPosition_); direction = normalize(direction); for (float k = 0.0; k < steps; k += 1.0) { .... pos += direction*delta_step; float thisLum = texture3D(texture3_, pos).r; if(thisLum > surface_) ... } Everything works as expected, what I now want is to sample the correct value to the depth buffer. The value that is now written to the depth buffer is the cube coordinate. But I want the value of pos in the 3d texture to be written. So lets say the cube is placed 10 away from origin in -z and the size is 10*10*10. My solution that does not work correctly is this: pos *= 10; pos.z += 10; pos.z *= -1; vec4 depth_vec = gl_ProjectionMatrix * vec4(pos.xyz, 1.0); float depth = ((depth_vec.z / depth_vec.w) + 1.0) * 0.5; gl_FragDepth = depth;

• AndEngine; Box2D - high speed body overlapping, prismatic joints

  - by Visher

  I'm trying to make good suspension for my car game, but I'm getting nervous of some problems with it. At the beginning, I've tried to make it out of one prismatic joint/revolute joint per one wheel only, but surprisingly prismatic joint that should only move in Y asix moves also in X axis, if car travels very fast, or even on low speeds if there's setContinuousPhysics = true. This causes wheels to "shift back", moving them away from axle. Now I've tried to add some bodies that will keep it in place: Suspension helper collides with spring only, wheel doesn't collide with spring&helper&vehicle body This is how I create those elements: rect = new Rectangle(1100, 1350, 200, 50, getVertexBufferObjectManager()); rect.setColor(Color.RED); scene.attachChild(rect); //rect.setRotation(90); Rectangle miniRect1 = new Rectangle(1102, 1355, 30, 50, getVertexBufferObjectManager()); miniRect1.setColor(0, 0, 1, 0.5f); miniRect1.setVisible(true);

• Installing Win32 shared SxS policy via WiX 3.0 MSM fails for 2nd app

  - by dr-stevep

  I am attempting to author a merge module for use by multiple application installers to install a Win32 Shared SxS Assembly and its associated Policy. I'm using WiX 3.0 to generate the MSM and test MSIs. So far it works fine for the first app installer that runs … but the second app installer fails because the Policy file already exists (HRESULT: 0x800700B7). What requirement(s) for correct Win32 Shared SxS Policy installation am I missing? I have submitted WiX bug 3005301 for this (https://sourceforge.net/tracker/?func=detail&atid=642714&aid=3005301&group_id=105970) and posted VS2008 projects that reproduce the problem. URL: ftp.digital-rapids.com/upload/SteveP/ User: drc-support Password: drc-support Link: ftp://drc-support:[email protected]/upload/SteveP/ wix-Bugs-3005201.rar contains a VS2008 solution that builds the MSM and MSIs that reproduce the issue.

• problem with loading in .FBX meshes in DirectX 10

  - by N0xus

  I'm trying to load in meshes into DirectX 10. I've created a bunch of classes that handle it and allow me to call in a mesh with only a single line of code in my main game class. How ever, when I run the program this is what renders: In the debug output window the following errors keep appearing: D3D10: ERROR: ID3D10Device::DrawIndexed: Input Assembler - Vertex Shader linkage error: Signatures between stages are incompatible. The reason is that Semantic 'TEXCOORD' is defined for mismatched hardware registers between the output stage and input stage. [ EXECUTION ERROR #343: DEVICE_SHADER_LINKAGE_REGISTERINDEX ] D3D10: ERROR: ID3D10Device::DrawIndexed: Input Assembler - Vertex Shader linkage error: Signatures between stages are incompatible. The reason is that the input stage requires Semantic/Index (POSITION,0) as input, but it is not provided by the output stage. [ EXECUTION ERROR #342: DEVICE_SHADER_LINKAGE_SEMANTICNAME_NOT_FOUND ] The thing is, I've no idea how to fix this. The code I'm using does work and I've simply brought all of that code into a new project of mine. There are no build errors and this only appears when the game is running The .fx file is as follows: float4x4 matWorld; float4x4 matView; float4x4 matProjection; struct VS_INPUT { float4 Pos:POSITION; float2 TexCoord:TEXCOORD; }; struct PS_INPUT { float4 Pos:SV_POSITION; float2 TexCoord:TEXCOORD; }; Texture2D diffuseTexture; SamplerState diffuseSampler { Filter = MIN_MAG_MIP_POINT; AddressU = WRAP; AddressV = WRAP; }; // // Vertex Shader // PS_INPUT VS( VS_INPUT input ) { PS_INPUT output=(PS_INPUT)0; float4x4 viewProjection=mul(matView,matProjection); float4x4 worldViewProjection=mul(matWorld,viewProjection); output.Pos=mul(input.Pos,worldViewProjection); output.TexCoord=input.TexCoord; return output; } // // Pixel Shader // float4 PS(PS_INPUT input ) : SV_Target { return diffuseTexture.Sample(diffuseSampler,input.TexCoord); //return float4(1.0f,1.0f,1.0f,1.0f); } RasterizerState NoCulling { FILLMODE=SOLID; CULLMODE=NONE; }; technique10 Render { pass P0 { SetVertexShader( CompileShader( vs_4_0, VS() ) ); SetGeometryShader( NULL ); SetPixelShader( CompileShader( ps_4_0, PS() ) ); SetRasterizerState(NoCulling); } } In my game, the .fx file and model are called and set as follows: Loading in shader file //Set the shader flags - BMD DWORD dwShaderFlags = D3D10_SHADER_ENABLE_STRICTNESS; #if defined( DEBUG ) || defined( _DEBUG ) dwShaderFlags |= D3D10_SHADER_DEBUG; #endif ID3D10Blob * pErrorBuffer=NULL; if( FAILED( D3DX10CreateEffectFromFile( TEXT("TransformedTexture.fx" ), NULL, NULL, "fx_4_0", dwShaderFlags, 0, md3dDevice, NULL, NULL, &m_pEffect, &pErrorBuffer, NULL ) ) ) { char * pErrorStr = ( char* )pErrorBuffer->GetBufferPointer(); //If the creation of the Effect fails then a message box will be shown MessageBoxA( NULL, pErrorStr, "Error", MB_OK ); return false; } //Get the technique called Render from the effect, we need this for rendering later on m_pTechnique=m_pEffect->GetTechniqueByName("Render"); //Number of elements in the layout UINT numElements = TexturedLitVertex::layoutSize; //Get the Pass description, we need this to bind the vertex to the pipeline D3D10_PASS_DESC PassDesc; m_pTechnique->GetPassByIndex( 0 )->GetDesc( &PassDesc ); //Create Input layout to describe the incoming buffer to the input assembler if (FAILED(md3dDevice->CreateInputLayout( TexturedLitVertex::layout, numElements,PassDesc.pIAInputSignature, PassDesc.IAInputSignatureSize, &m_pVertexLayout ) ) ) { return false; } model loading: m_pTestRenderable=new CRenderable(); //m_pTestRenderable->create<TexturedVertex>(md3dDevice,8,6,vertices,indices); m_pModelLoader = new CModelLoader(); m_pTestRenderable = m_pModelLoader->loadModelFromFile( md3dDevice,"armoredrecon.fbx" ); m_pGameObjectTest = new CGameObject(); m_pGameObjectTest->setRenderable( m_pTestRenderable ); // Set primitive topology, how are we going to interpet the vertices in the vertex buffer md3dDevice->IASetPrimitiveTopology( D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST ); if ( FAILED( D3DX10CreateShaderResourceViewFromFile( md3dDevice, TEXT( "armoredrecon_diff.png" ), NULL, NULL, &m_pTextureShaderResource, NULL ) ) ) { MessageBox( NULL, TEXT( "Can't load Texture" ), TEXT( "Error" ), MB_OK ); return false; } m_pDiffuseTextureVariable = m_pEffect->GetVariableByName( "diffuseTexture" )->AsShaderResource(); m_pDiffuseTextureVariable->SetResource( m_pTextureShaderResource ); Finally, the draw function code: //All drawing will occur between the clear and present m_pViewMatrixVariable->SetMatrix( ( float* )m_matView ); m_pWorldMatrixVariable->SetMatrix( ( float* )m_pGameObjectTest->getWorld() ); //Get the stride(size) of the a vertex, we need this to tell the pipeline the size of one vertex UINT stride = m_pTestRenderable->getStride(); //The offset from start of the buffer to where our vertices are located UINT offset = m_pTestRenderable->getOffset(); ID3D10Buffer * pVB=m_pTestRenderable->getVB(); //Bind the vertex buffer to input assembler stage - md3dDevice->IASetVertexBuffers( 0, 1, &pVB, &stride, &offset ); md3dDevice->IASetIndexBuffer( m_pTestRenderable->getIB(), DXGI_FORMAT_R32_UINT, 0 ); //Get the Description of the technique, we need this in order to loop through each pass in the technique D3D10_TECHNIQUE_DESC techDesc; m_pTechnique->GetDesc( &techDesc ); //Loop through the passes in the technique for( UINT p = 0; p < techDesc.Passes; ++p ) { //Get a pass at current index and apply it m_pTechnique->GetPassByIndex( p )->Apply( 0 ); //Draw call md3dDevice->DrawIndexed(m_pTestRenderable->getNumOfIndices(),0,0); //m_pD3D10Device->Draw(m_pTestRenderable->getNumOfVerts(),0); } Is there anything I've clearly done wrong or are missing?

  I am trying to integrate In App Purchases in my app made by using cocos2d x c++. I am using easyNdk Helper for In App Purchases. My In App Purchases works perfectly for my Objective C apps. But for cocos2d x it is throwing error for the following line if ([[RageIAPHelper sharedInstance] productPurchased:productP.productIdentifier]) Actually value came from CPP file perfectly in form of arguments and Properly shows their value in NSLog , But it always shows the objects as nil even objetcs print their stored value in NSLog also @try catch condition is not working and finally throw the following error Please Help me what i have to do ?

• Vehicle: Boat accelerating and turning in Unity

  - by Emilios S.

  I'm trying to make a player-controllable boat in Unity and I'm running into problems with my code. 1) I want to make the boat to accelerate and decelerate steadily instead of simply moving the speed I'm telling it to right away. 2) I want to make the player unable to steer the boat unless it is moving. 3) If possible, I want to simulate the vertical floating of a boat during its movement (it going up and down) My current code (C#) is this: using UnityEngine; using System.Collections; public class VehicleScript : MonoBehaviour { public float speed=10; public float rotationspeed=50; // Use this for initialization // Update is called once per frame void Update () { // Forward movement if(Input.GetKey(KeyCode.I)) speed = transform.Translate (Vector3.left*speed*Time.deltaTime); // Backward movement if(Input.GetKey(KeyCode.K)) transform.Translate (Vector3.right*speed*Time.deltaTime); // Left movement if(Input.GetKey(KeyCode.J)) transform.Rotate (Vector3.down*rotationspeed*Time.deltaTime); // Right movement if(Input.GetKey(KeyCode.L)) transform.Rotate (Vector3.up*rotationspeed*Time.deltaTime); } } In the current state of my code, when I press the specified keys, the boat simply moves 10 units/sec instantly, and also stops instantly. I'm not really sure how to make the things stated above, so any help would be appreciated. Just to clarify, I don't necessarily need the full code to implement those features, I just want to know what functions to use in order to achieve the desired effects. Thank you very much.

• Best pathfinding for a 2D world made by CPU Perlin Noise, with random start- and destinationpoints?

  - by Mathias Lykkegaard Lorenzen

  I have a world made by Perlin Noise. It's created on the CPU for consistency between several devices (yes, I know it takes time - I have my techniques that make it fast enough). Now, in my game you play as a fighter-ship-thingy-blob or whatever it's going to be. What matters is that this "thing" that you play as, is placed in the middle of the screen, and moves along with the camera. The white stuff in my world are walls. The black stuff is freely movable. Now, as the player moves around he will constantly see "monsters" spawning around him in a circle (a circle that's larger than the screen though). These monsters move inwards and try to collide with the player. This is the part that's tricky. I want these monsters to constantly spawn, moving towards the player, but avoid walls entirely. I've added a screenshot below that kind of makes it easier to understand (excuse me for my bad drawing - I was using Paint for this). In the image above, the following rules apply. The red dot in the middle is the player itself. The light-green rectangle is the boundaries of the screen (in other words, what the player sees). These boundaries move with the player. The blue circle is the spawning circle. At the circumference of this circle, monsters will spawn constantly. This spawncircle moves with the player and the boundaries of the screen. Each monster spawned (shown as yellow triangles) wants to collide with the player. The pink lines shows the path that I want the monsters to move along (or something similar). What matters is that they reach the player without colliding with the walls. The map itself (the one that is Perlin Noise generated on the CPU) is saved in memory as two-dimensional bit-arrays. A 1 means a wall, and a 0 means an open walkable space. The current tile size is pretty small. I could easily make it a lot larger for increased performance. I've done some path algorithms before such as A*. I don't think that's entirely optimal here though.

• Ingame menu is not working correctly

  - by Johnny

  The ingame menu opens when the player presses Escape during the main game. If the player presses Y in the ingame menu, the game switches to the main menu. Up to here, everything works. But: On the other hand, if the player presses N in the ingame menu, the game should switch back to the main game(should resume the main game). But that doesn't work. The game just rests in the ingame menu if the player presses N. I set a breakpoint in this line of the Ingamemenu class: KeyboardState kbState = Keyboard.GetState(); CurrentSate/currentGameState and LastState/lastGameState have the same state: IngamemenuState. But LastState/lastGameState should not have the same state than CurrentSate/currentGameState. What is wrong? Why is the ingame menu not working correctly? public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; IState lastState, currentState; public enum GameStates { IntroState = 0, MenuState = 1, MaingameState = 2, IngamemenuState = 3 } public void ChangeGameState(GameStates newState) { lastGameState = currentGameState; lastState = currentState; switch (newState) { case GameStates.IntroState: currentState = new Intro(this); currentGameState = GameStates.IntroState; break; case GameStates.MenuState: currentState = new Menu(this); currentGameState = GameStates.MenuState; break; case GameStates.MaingameState: currentState = new Maingame(this); currentGameState = GameStates.MaingameState; break; case GameStates.IngamemenuState: currentState = new Ingamemenu(this); currentGameState = GameStates.IngamemenuState; break; } currentState.Load(Content); } public void ChangeCurrentToLastGameState() { currentGameState = lastGameState; currentState = lastState; } public GameStates CurrentState { get { return currentGameState; } set { currentGameState = value; } } public GameStates LastState { get { return lastGameState; } set { lastGameState = value; } } private GameStates currentGameState = GameStates.IntroState; private GameStates lastGameState; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void Initialize() { ChangeGameState(GameStates.IntroState); base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); currentState.Load(Content); } protected override void Update(GameTime gameTime) { currentState.Update(gameTime); if ((lastGameState == GameStates.MaingameState) && (currentGameState == GameStates.IngamemenuState)) { lastState.Update(gameTime); } base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); if ((lastGameState == GameStates.MaingameState) && (currentGameState == GameStates.IngamemenuState)) { lastState.Render(spriteBatch); } currentState.Render(spriteBatch); spriteBatch.End(); base.Draw(gameTime); } } public interface IState { void Load(ContentManager content); void Update(GameTime gametime); void Render(SpriteBatch batch); } public class Intro : IState { Texture2D Titelbildschirm; private Game1 game1; public Intro(Game1 game) { game1 = game; } public void Load(ContentManager content) { Titelbildschirm = content.Load<Texture2D>("gruft"); } public void Update(GameTime gametime) { KeyboardState kbState = Keyboard.GetState(); if (kbState.IsKeyDown(Keys.Space)) game1.ChangeGameState(Game1.GameStates.MenuState); } public void Render(SpriteBatch batch) { batch.Draw(Titelbildschirm, new Rectangle(0, 0, 1280, 720), Color.White); } } public class Menu:IState { Texture2D Choosescreen; private Game1 game1; public Menu(Game1 game) { game1 = game; } public void Load(ContentManager content) { Choosescreen = content.Load<Texture2D>("menubild"); } public void Update(GameTime gametime) { KeyboardState kbState = Keyboard.GetState(); if (kbState.IsKeyDown(Keys.Enter)) game1.ChangeGameState(Game1.GameStates.MaingameState); if (kbState.IsKeyDown(Keys.Escape)) game1.Exit(); } public void Render(SpriteBatch batch) { batch.Draw(Choosescreen, new Rectangle(0, 0, 1280, 720), Color.White); } } public class Maingame : IState { Texture2D Spielbildschirm, axe; Vector2 position = new Vector2(100,100); private Game1 game1; public Maingame(Game1 game) { game1 = game; } public void Load(ContentManager content) { Spielbildschirm = content.Load<Texture2D>("hauszombie"); axe = content.Load<Texture2D>("axxx"); } public void Update(GameTime gametime) { KeyboardState keyboardState = Keyboard.GetState(); float delta = (float)gametime.ElapsedGameTime.TotalSeconds; position.X += 5 * delta; position.Y += 3 * delta; if (keyboardState.IsKeyDown(Keys.Escape)) game1.ChangeGameState(Game1.GameStates.IngamemenuState); } public void Render(SpriteBatch batch) { batch.Draw(Spielbildschirm, new Rectangle(0, 0, 1280, 720), Color.White); batch.Draw(axe, position, Color.White); } } public class Ingamemenu : IState { Texture2D Quitscreen; private Game1 game1; public Ingamemenu(Game1 game) { game1 = game; } public void Load(ContentManager content) { Quitscreen = content.Load<Texture2D>("quit"); } public void Update(GameTime gametime) { KeyboardState kbState = Keyboard.GetState(); if (kbState.IsKeyDown(Keys.Y)) game1.ChangeGameState(Game1.GameStates.MenuState); if (kbState.IsKeyDown(Keys.N)) game1.ChangeCurrentToLastGameState(); } public void Render(SpriteBatch batch) { batch.Draw(Quitscreen, new Rectangle(200, 200, 200, 200), Color.White); } }

• per pixel based collision detection.

  - by pengume

  I was wondering if anyone had any ideas on how to get per pixel collision detection for the android. I saw that the andEngine has great collision detection on rotation as well but couldn't see where the actual detection happened per pixel. Also noticed a couple solutions for java, could these be replicated for use with the Android SDK? Maybe someone here has a clean piece of code I could look at to help understand what is going on with per pixel detection and also why when rotating it is a different process.

• flicker when drawing 4 models for the first time

  - by Badescu Alexandru

  i have some models that i only draw at a certain moment in the game (after some seconds since the game has started). The problem is that in that first second when i start to draw the models, i see a flicker (in the sence that everything besides those models, dissapears, the background gets purple). The flicker only lasts for that frame, and then everything seems to run the way it should. UPDATE I see now that regardless of the moment i draw the models, the first frame has always the flickering aspect What could this be about? i'll share my draw method: int temp = 0; foreach (MeshObject meshObj in ShapeList) { foreach (BasicEffect effect in meshObj.mesh.Effects) { #region color elements int i = int.Parse(meshObj.mesh.Name.ElementAt(1) + ""); int j = int.Parse(meshObj.mesh.Name.ElementAt(2) + ""); int getShapeColor = shapeColorList.ElementAt(i * 4 + j); if (getShapeColor == (int)Constants.shapeColor.yellow) effect.DiffuseColor = yellow; else if (getShapeColor == (int)Constants.shapeColor.red) effect.DiffuseColor = red; else if (getShapeColor == (int)Constants.shapeColor.green) effect.DiffuseColor = green; else if (getShapeColor == (int)Constants.shapeColor.blue) effect.DiffuseColor = blue; #endregion #region lighting effect.LightingEnabled = true; effect.AmbientLightColor = new Vector3(0.25f, 0.25f, 0.25f); effect.DirectionalLight0.Enabled = true; effect.DirectionalLight0.Direction = new Vector3(-0.3f, -0.3f, -0.9f); effect.DirectionalLight0.SpecularColor = new Vector3(.7f, .7f, .7f); Vector3 v = Vector3.Normalize(new Vector3(-100, 0, -100)); effect.DirectionalLight1.Enabled = true; effect.DirectionalLight1.Direction = v; effect.DirectionalLight1.SpecularColor = new Vector3(0.6f, 0.6f, .6f); #endregion effect.Projection = camera.projectionMatrix; effect.View = camera.viewMatrix; if (meshObj.isSetInPlace == true) { effect.World = transforms[meshObj.mesh.ParentBone.Index] * gameobject.orientation; // draw in original cube-placed position meshObj.mesh.Draw(); } else { effect.World = meshObj.Orientation; // draw inSetInPlace position meshObj.mesh.Draw(); } } temp++; }

• Generating Normal map from a Image with a given Albedo map

  - by snape

  I am working on a research problem part of which involves generating normal map from a given image of a rusted object. I searched the internet for techniques to achieve the above and apparently crazybump is mentioned a lot. I tried it but it didn't produce the desirable effects. Also I am looking for a method which draws inspiration from an existing research paper not some closed source software. I turned my attention to the technique described in the this paper. Results from this technique are satisfactory for normal objects because of bias in the training data but it doesn't work very well in the case of rusted objects. After this I focussed my attention on generating Albedo map (the above problem would become more solvable if Albedo map is obtained). Fortunately I am able to generate pretty good albedo maps for images of rusted objects. I used this paper's approach to generate Albedo maps. Now I want to know a good technique to get Normal map given an image and it's corresponding Albedo map. To give you an idea of what kind of images I am working with I am attaching a sample. Links to research material would be really appreciated. Thanks!

• farseer physics xbox samples not working

  I have downloaded a few of the sample projects from the official farseer physics website and i just cant get them to run on my xbox. -My connection to the xbox is fine, other xbox projects debug fine on my xbox -I have tried running both the xbox versions of the samples (for example the farseer hello world sample project) and the windows version by right-clicking the project and making a copy for xbox. I get a bunch of errors but what i always get is "unreachable code detected" referring to code in the farseer library, it seems to be a problem to do with referencing/linking the farseer library to the main game project. Help please!

• How to manage a multiplayer asynchronous environment in a game

  - by Phil

  I'm working on a game where players can setup villages, which can contain defending units. Any of these units (each on their own tiles) can be set to "campaign" which means they are no longer defending but can now be used to attack other villages. And each unit on a tile can have up to a 100 health. So far so good. Oh and it's all asynchronous so even though the server will be aware that your village is being attacked, you won't be until the attack is over. The issue I'm struggling with, is the following situation. Let's say a unit on a tile is being attacked by a player from another village. The other player see's your village and is attacking your units. You don't know this is happening though, so you set your unit to campaign and off you go to attack another village, with the unit which itself is actually being attacked by this other player. The other player stops attacking your village and leaves your unit with say a health of 1, which is then saved to the server. You however have this same unit are attacking another village with it, but now you discover that even though it started off with a 100 health, now mysteriously it only has 1... Solutions? Ideas? Edit The simplest solutions are often the best. I referred to Clash of clans below, well after a bit more digging it seems that in CoC you can only attack players that are offline! ha, that almost solves the problem. I say almost because there's still the situation where a players village could be in the process of being attacked when they come back online, still need to address that. Edit 2 A solution to the "What happens when a player is attacking your village and you come online" issue, could be the attacking player just get's kicked out of the village at that point and just get's whatever they had won up to that point, it's a bit of a fudge but it might work.

• How can I make an object's hitbox rotate with its texture?

  - by Matthew Optional Meehan

  In XNA, when you have a rectangular sprite that doesnt rotate, it's easy to get its four corners to make a hitbox. However, when you do a rotation, the points get moved and I assume there is some kind of math that I can use to aquire them. I am using the four points to draw a rectangle that visually represents the hitboxes. I have seen some per-pixel collision examples, but I can forsee they would be hard to draw a box/'convex hull' around. I have also seen physics like farseer but I'm not sure if there is a quick tutorial to do what I want.

• copyright of some arcade classics [closed]

  - by kamziro

  Possible Duplicate: How closely can a game resemble another game without legal problems So suppose I'm currently developing a variant of a snakes game for the iPhone, and you decided to call it "snakes". First, in general, how would you find out if a name's been copyrighted or not? It's probably safe with "snakes" because it's such a common word, and that there's been so many games around (please correct me if I'm wrong), but with some people copyrighting the name "edge", it would be best to be a bit careful. Second, suppose I decided to go with some name that is guaranteed to be different (e.g EL SERPENTES DE LOS REYES), would gameplay be a point of contention on copyright issues? For example, the tetris game is sort of "copyrighted" at the apple app store, and there was a crackdown on anyone using the word "tris" or anything related to it. However, if there was a game with the gameplay of tetris (or loosely very similar), with the name "BLOXODEREX", can it be liable to copyright/DMCA issues?
