• Java single Array best choice for accessing pixels for manipulation?

  - by Petrol

  I am just watching this tutorial https://www.youtube.com/watch?v=HwUnMy_pR6A and the guy (who seems to be pretty competent) is using a single array to store and access the pixels of his to-be-rendered image. I was wondering if this really is the best way to do this. The alternative of Multi-Array does have one pointer more, but Arrays do have an O(1) for accessing each index and calculating the index in a single array seems to take one addition and one multiplication operation per pixel. And if Multi-Arrays really are bad, can't you use something with Hashing to avoid those addition and multiplication operations? EDIT: here is his code... public class Screen { private int width, height; public int[] pixels; public Screen(int width, int height) { this.width = width; this.height = height; // creating array the size of one index/int for every pixel // single array has better performance than multi-array pixels = new int[width * height]; } public void render() { for (int y = 0; y < height; y++) { for (int x = 0; x < width; x++) { pixels[x + y * width] = 0xff00ff; } } } }

• Android - Unity3D: setVisibility(View.VISIBLE) crashes

  - by Kazoeja

  I have a unity project and I use a Android (java) plugin to get camera data. I draw this on a TextureView. I want to hide/show this view when I press a button in unity. But my app crashes when I setVisibility onCreate UnityPlayer.currentActivity.addContentView(texView, new FrameLayout.LayoutParams(400, 400)); java: public void HideVideo() { //Hide view _TextureView.setVisibility(View.INVISIBLE); } Is there an extra function I need to call, or may I only call it on certain times? None of these thins work, they all make my app crash. _TextureView.setVisibility(View.INVISIBLE); _TextureView.setActivated(false); _TextureView.setAlpha(0); _TextureView.setTranslationY(-1000);

• How do I render from one render target to another?

  - by Chaotikmind

  I have two render targets: a fake backbuffer; a special render target where I do all my rendering. a light render target; where I render my light fx. I'm sure I'm rendering correctly on both. The problem arises when I overlay the light render target onto the fake backbuffer by drawing a quad covering it: DxEngine.DrawSprite(0.0f, 0.0f, 0.0f, (float)DxEngine.GetWidth(), (float)DxEngine.GetHeight(), 0xFFFFFFFF, LightSurface->GetTexture()); Regardless of what's in the light target, nothing is rendered onto the other target. I tried clearing the light target with full-white or full-black, but still get nothing. Fake backbuffer created with Direct3dDev->CreateTexture(Width, Height, 1, D3DUSAGE_RENDERTARGET, D3DFMT_X8R8G8B8, D3DPOOL_DEFAULT, &Texture, nullptr); Light render target created with Direct3dDev->CreateTexture(Width, Height, 1, D3DUSAGE_RENDERTARGET, D3DFMT_A8R8G8B8, D3DPOOL_DEFAULT, &Texture, nullptr); I also tried to create both with D3DFMT_A8R8G8B8, again without difference. Both targets have the same width and height. Only the fixed pipeline is used DirectX setup for rendering : Direct3dDev->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR ); Direct3dDev->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR ); Direct3dDev->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_NONE ); Direct3dDev->SetSamplerState(0, D3DSAMP_ADDRESSU, D3DTADDRESS_WRAP ); Direct3dDev->SetSamplerState(0, D3DSAMP_ADDRESSV, D3DTADDRESS_WRAP ); Direct3dDev->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE); Direct3dDev->SetRenderState(D3DRS_LIGHTING, false); Direct3dDev->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE); Direct3dDev->SetRenderState(D3DRS_ZWRITEENABLE,D3DZB_TRUE); Direct3dDev->SetRenderState(D3DRS_ZFUNC,D3DCMP_LESSEQUAL); Direct3dDev->SetRenderState(D3DRS_ALPHABLENDENABLE, true ); Direct3dDev->SetRenderState(D3DRS_ALPHAREF, 0x00000000ul); Direct3dDev->SetRenderState(D3DRS_ALPHATESTENABLE, true); Direct3dDev->SetRenderState(D3DRS_ALPHAFUNC,D3DCMP_GREATER); Direct3dDev->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA ); Direct3dDev->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA ); Direct3dDev->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE); Direct3dDev->SetTextureStageState(0, D3DTSS_COLORARG2, D3DTA_DIFFUSE); Direct3dDev->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_MODULATE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAARG2, D3DTA_DIFFUSE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAOP, D3DTOP_MODULATE); Direct3dDev->SetTextureStageState(0, D3DTSS_RESULTARG, D3DTA_CURRENT); Direct3dDev->SetTextureStageState(0, D3DTSS_TEXCOORDINDEX, D3DTSS_TCI_PASSTHRU); //ensure the first stage is not used for now Direct3dDev->SetTextureStageState(1, D3DTSS_COLOROP, D3DTOP_DISABLE); How can I do this right?

• Simulating water droplets on a window

  - by skyuzo

  How do I simulate water droplets realistically falling, gathering, and flowing down a window? For example, see http://www.youtube.com/watch?v=4jaGyv0KRPw. In particular, I want to simulate how smaller droplets merge together to form larger droplets that have enough weight to oppose the surface tension and flow downward, leaving a trail of water. I'm aware of fluid simulation, but how would it be applied in this situation?

• Are there any resources for motion-planning puzzle design?

  - by Salano Software

  Some background: I'm poking at a set of puzzles along the lines of Rush Hour/Sokoban/etc; for want of a better description, call them 'motion planning' puzzles - the player has to figure out the correct sequence of moves to achieve a particular configuration. (It's the sort of puzzle that's generically PSPACE-complete if that actually helps anyone's mental image). While I have a few straightforward 'building blocks' that I can use for puzzle crafting and I have a few basic examples put together, I'm trying to figure out how to avoid too much sameness over a large swath of these kinds of puzzles, and I'm also trying to figure out how to make puzzles that have more of a feel of logical solution than trial-and-error. Does anyone know of good resources out there for designing instances of this sort of puzzle once the core puzzle rules are in place? Most of what I've found on puzzle design only covers creating the puzzle rules, not building interesting puzzles out of a set of rules.

• If I project a sphere in 3D will it be a circle?

  - by yuumei

  Assuming I have infinite vertices to represent the sphere, if I project the sphere from any position/scale in 3D to 2D, will it be a circle? I know it will not be a circle on the screen, because of scaling and different resolutions. But do field of view and aspect ratio effect the results? Edit: Sorry yes, I am talking about perspective projection. Seems the answer is no then, perspective will distort the sphere. Thanks!

• Create a Texture2D from larger image

  - by Dialock

  I am having trouble with the basic logic of this solution: Xna: Splitting one large texture into an array of smaller textures in respect to my specific problem (specifically, I'm looking at the second answer.) How can I use my source rectangle that I already use for drawing to create a new Texture2D? spriteBatch.Draw(CurrentMap.CollisionSet, currentMap.CellScreenRectangle(x, y), CurrentMap.TileSourceRectangle(currentMap.MapCells[x, y].TileDepths[4]), Color.FromNonPremultiplied(0,0,0, 45), 0.0f, Vector2.Zero, SpriteEffects.None, 0.91f); I know I want a method that I started so: //In Update Method of say the player's character. Texture2D CollisionTexture = ExtractTexture(MapManager.CurrentMap.CollisionSet, MapManager.TileWidth, MapManager.TileHeight); // In MapManager Class who knows everything about tiles that make up a level. public Texture2D ExtractTexture(Texture2D original, int partWidth, int partheight, MapTile mapCell) { var dataPerPart = partWidth * partheight; Color[] originalPixelData = new Color[original.Width * original.Height]; original.GetData<Color>(originalPixelData); Color[] newTextureData = new Color[dataPerPart]; original.GetData<Color>(0, CurrentMap.TileSourceRectangle(mapCell.TileDepths[4]), originalPixelData, 0, originalPixelData.Count()); Texture2D outTexture = new Texture2D(original.GraphicsDevice, partWidth, partheight); } I think the problem is I'm just not understanding the overload of Texture2D.GetData< Part of my concern is creating an array of the whole texture in the first place. Can I target the original texture and create an array of colors for copying based on what I already get from the method TileSourceRecatangle(int)?

• fast 3d point -> cuboid volume intersection test

  - by user1130477

  Im trying to test whether a point lies within a 3d volume defined by 8 points. I know I can use the plane equation to check that the signed distance is always -1 for all 6 sides, but does anyone know of a faster way or could point me to some code? Thanks EDIT: I should add that ideally the test would produce 3 linear interpolation parameters which would lie in the range 0..1 to indicate that the point is within the volume for each axis (since I will have to calculate these later if the point is found to be in the volume)

• How do I swap two objects in C# (specifically Mono) without triggering GC?

  - by TenFour04

  I have two array lists. that I want to swap each frame. My question is, does the variable 'temp' need to be a member variable to avoid triggering GC, assuming this method is called on dozens of objects each frame? I'm not creating a new object, just a new reference to an object. public void LateUpdate(){ ArrayList<int> temp = previousFrameCollisions; previousFrameCollisions = currentFrameCollisions; currentFrameCollisions = temp; currentFrameCollisions.clear(); } I've been told there's no reason to make a primitive into a member variable just to avoid GC, so my best guess is that this also applies to object references.

• UDK: Toggle Material on Brushes?

  - by user50300

  I'm attempting to change / toggle the material that's applied to a BSP brush. I've seen where it's possible on static meshes, but I can't seem to get it to work on brushes. Below is an example scenario. The ground (BSP Brush) is covered in a stone material The player hits a trigger. A new "moss" material is applied to the brush, removing the old stone material. Any assistance you could offer would be greatly appreciated.

• Basic Use of ApplyImpulse

  I am trying to apply a force to a bunch of b2_dynamicBodys, but it seems to only work for a random number of items and then stops with an error. //create some items to move bodyDef.type = b2Body.b2_dynamicBody; for(var i = 0; i < 5; ++i) { fixDef.shape = new b2PolygonShape; fixDef.shape.SetAsBox(1,1); fixDef.friction = 1; fixDef.restitution = .1; bodyDef.position.x = Math.random() * 10; bodyDef.position.y = Math.random() * 10; bodyDef.linearDamping=1; bodyDef.angularDamping=.8; itemsArray.push(world.CreateBody(bodyDef).CreateFixture(fixDef)); // store for later } then i try to apply a force later with: angle = 20; for (var xIdx=0; xIdx<itemArray.length; xIdx++) { itemsArray[xIdx].GetBody().ApplyImpulse(new b2Vec2(50*Math.cos(angle*Math.PI/180),50*Math.sin(angle*Math.PI/180));); } the error I receive is TypeError: 'undefined' is not an object (evaluating 'c.x') Is there something wrong with saving the items for later use when I am creating them? Does anyone know what is causing this.

• Vector normalization gives very imprecise results

  - by Kipras

  When I normalize vectors I receive very strange results. The lengths of the normalized vectors range from 1.0 to almost 1.5. The functions are all written by me, but I just can't find a mistake in my algorithm. When I normalize I just divide all components of the vector by the vector's length. public double length(){ return Math.sqrt(x*x + y*y); } public void normalize(){ if(length() > 0){ x /= length(); y /= length(); } } Is this supposed to happen? I mean I can see the length ranging from 0.9 to 1.1 at worst, but this is just overwhelming. Cheers

• Having a list of rooms with theirs connection to each other, how do I find isolated room groups?

  - by petervaz

  I'm trying to create a small roguelike and went as far as random generating rooms and corridors. Each room is an instanced object and contain an arraylist of the others rooms connected by a corridor. I can single out unconnected rooms but how can I know the rooms that are connected only to each other but not to most of the others, forming an island? to illustrated better the problem here is an image from the console on a bogged level. Rooms 5 and 6 are connected only to each other. What algorithm can I use to detect that?

  I have tried to start programing with coco2dx but i have no idea where to start and the tutorials are no very not very helpful. What i am looking for is some tutorials/guides on how to begin using cocos2dx for the total beginner. Things like how to setup a project and run it and how to do simple things like draw graphics on the screen, play sounds and get input. I am running on windows 7 and have been told by the cocos2dx wiki that this may cause problems so if anyone has a solution to this that would also be helpful.

• Intersection of player and mesh

  - by Will

  I have a 3D scene, and a player that can move about in it. In a time-step the player can move from point A to point B. The player should follow the terrain height but slow going up cliffs and then fall back, or stop when jumping and hitting a wall and so on. In my first prototype I determine the Y at the player's centre's X,Z by intersecting a ray with every triangle in the scene. I am not checking their path, but rather just sampling their end-point for each tick. Despite this being Javascript, it works acceptably performance-wise. However, because I am modeling the player as a single point, the player can position themselves so that they are half-in a cliff face and so on. I need to model them as as a solid e.g. some cluster of spheres or a even their fuller mesh. I am also concerned that if they were moving faster they might miss the test altogether. How should I solve this?

• How to find collision detection side between two objects?

  - by user2362369

  I am using box2D and I have two objects, one is bouncy ball and the other one is block. I'd like to find which side of the block is collided with, so I can only make the ball bounce when it hits the top. I tried to implement many things like fixture data and by detecting position, using manifold but not get the accurate result. I also tried to calculate distance between two object but all went wrong.

• rigidbody2d.Addforce( ) behaves wieirdly unity 4.3 [on hold]

  - by Lilz Votca Love

  So guys ive edited the question and here is what my problem is i have a player which has a rigidbody2d attached to it.my player is able to doublejump in the air nicely and stick to walls when colliding with them and slowly slides to the ground.All movement is handle through physics and no transform manipulations.here i did something similar to this in the FixedUpdate of my player. void FixedUpdate() { if(wall && Input.GetButtonDown("Jump")) { if(facingright)//player is facing the left side of the wall { rigidbody2D.Addforce(new vector2(-1f,2f)*jumpforce); /*Now the player should jump backwards following this directional vector and should follow a smooth curve which in this part works well*/ } else { rigidbody2D.Addforce(new vector2(1f,2f)*jumpforce); /*Now this is where everything gets complicated as you should have noticed this is the same directional vector only the opposite x axis value and the same amount of force is used but it behaves like the red curve in the picture below*/ } } } bad behaviour and vector in red .I tested the same thing(both addforce methods) for a simple jump and they exactly behave like mentionned above in the picture.so here is my problem.Jumping diagonally forward with rigidbody2d.addforce() do not have the same impact,do not follow the same curve as jumping the opposite direction with the same exact amount of force.if i could fix this or get past this i could implement a walljump system like a ninja jumping in zigzag between two opposite wall to climb them.Any ideas or alternatives?

• Multiple passes in direct3d10

  I begin to learning direct3d10 and stuck with multiple passes. As input I have a triangle(that stored in vb/ib) and effect file: //some vertex shader and globals goes there. skip them to preserve simplicity float4 ColorPixelShader(PixelInputType input) : SV_Target { return float4(1,0,0,0); } float4 ColorPixelShader1(PixelInputType input) : SV_Target { return float4(0,1,0,0); } technique10 ColorTechnique { pass pass0 { SetVertexShader(CompileShader(vs_4_0, ColorVertexShader())); SetPixelShader(CompileShader(ps_4_0, ColorPixelShader())); SetGeometryShader(NULL); } pass pass1 { SetVertexShader(CompileShader(vs_4_0, ColorVertexShader())); SetPixelShader(CompileShader(ps_4_0, ColorPixelShader1())); SetGeometryShader(NULL); } } And some render code: pass1->Apply(0); device->DrawIndexed(indexCount, 0, 0); pass2->Apply(0); device->DrawIndexed(indexCount, 0, 0); What I'd expect to see is the green triangle, but it always shows me red triangle. What am I doing wrong? Also, I've got another question - should I set vertex shader in every pass? I've added ColorVertexShader1 that translates vertex position by some delta, and 've got following picture: http://imgur.com/Oe7Qj

• Building a touch event driven UI from scratch: what algorithms or data types?

  - by user1717079

  I have a touch display. As input I can receive the coordinates and how many touch points are in use, basically I just get an X,Y couple for every touch event/activated point at a customizable rate. I need to start from this and build my own callback system to achieve something like Object.onUp().doSomething() meaning that I would like to abstract just the detection of some particular movements and not having to deal with raw data: what algorithms can be useful in this case? What statements? Is there some C++ library that I can dissect to get some useful info? Would you suggest the use of an heuristic algorithm?

• Reasons why AppHub samples won't build?

  - by user13909

  I have an issue off of most downloaded projects where whenever I build it, VS2010 just crashes. I had this issue a while before, and it was widespread, I reinstalled, and it worked fine afterwards. If I create my own XNA project, and copy all of classes and assets over (which I admit, is super fun anyway) things build fine. But if I just download the project from here http://create.msdn.com/en-US/education/catalog/sample/roleplaying_game (RolePlayingGame_4_0_Win_Xbox.zip) and try to build, it automatically stops working, restarts, and reopens the project. If I Debug/Deploy to my Xbox, I do get a sucessful version to the Xbox, but VS2010 still stops and restarts. I've already repaired, and reinstalled again, still having the issue. Can anything think of plausible solutions?

• XNA + Windows Forms: How make them work together without making the trick of the custom GraphicsDeviceControl?

  - by Renann

  What I've found is a solution where you have to code a custom GraphicsDeviceControl to put inside the form (the well known tutorial from the APPHub), but that's not what I'm searching for. I would like to say that before start to right my question here, I "googled" a lot and I saw some questions here, but I couldn't find what I'm looking for. I would like to have the Draw/Update loops completly managed by XNAFrameWork (with XNA project and so), and not by a custom component. I hope you understand what I asked. Thanks in advance. Edit What's the most important thing for me and wasn't shown in the tutorial of APPHub is: where I have to put the input handling? That's one the problems that wasn't covered by the tutorial.
