• Video playback in games - formats & decoding

  - by snake5

  What free / non-restrictive open-source solutions (not GPL) are available for decoding game videos? The requirements are simple: a relatively easy to use C API encoded files must be quite small there must be an application that converts videos from any format (whatever codec is installed on Windows or equivalent amount of internally decoded formats) decoding has to happen fairly quickly bonus points go to file formats that are popular / actively supported and developed

• Multi Threading - How to split the tasks

  - by Motig

  if I have a game engine with the basic 'game engine' components, what is the best way to 'split' the tasks with a multi-threaded approach? Assuming I have the standard components of: Rendering Physics Scripts Networking And a quad-core, I see two ways of multi-threading: Option A ('Vertical'): Using this approach I can allow one core for each component of the engine; e.g. one core for the Rendering task, one for the Physics, etc. Advantages: I do not need to worry about thread-safety within each component I can take advantage of special optimizations provided for single-threaded access (e.g. DirectX offers a flag that can be set to tell it that you will only use single-threading) Option B ('Horizontal'): Using this approach, each task may be split up into 1 <= n <= numCores threads, and executed simultaneously, one after the other. Advantages: Allows for work-sharing, i.e. each thread can take over work still remaining as the others are still processing I can take advantage of libraries that are designed for multi-threading (i.e. ... DirectX) I think, in retrospect, I would pick Option B, but I wanted to hear you guys' thoughts on the matter.

• point to rectangle distance

  - by john smith

  I have a 2D rectangle with x, y position and it's height and width and a randomly positioned point nearby it. Is there a way to check if this point might collide with the rectangle if closer than a certain distance? like imagine an invisible radius outside of that point colliding with said rectangle. I have problems with this simply because it is not a square, it would be so much easier this way! Any help? Thanks in advance.

• Trouble with Collada bones

  - by KyleT

  I have a Collada file with a rigged mesh. I've read the node tags in the library_visual_scenes tag and extracted the matrix for each node and stored everything in a hierarchical bone structure. My Matrix container is "row major", so I'd store the first float of a matrix tag in the 1st row, 1st column, the second in the 1st row, 2nd column, etc. From what I gather this is the Bind Pose Matrix. After that I went through the tag and extracted the float array in the source tag of the skin tag of the controller for the mesh. I stored each matrix from this float array in their corresponding Bone as the Inverse Bind Matrix. I also extracted the bind-shape-matrix and stored it. Now I'd like to draw the skeleton with OpenGL to see if everything is working correctly before I go about skinning. I iterate once over my bones and multiply a bone's Bind Pose Matrix by it's parents and store that. After that I iterate again over the bones and multiply the result of the previous matrix multiplication by the Inverse Bind Matrix and then by the Bind Shape Matrix. The results look something like this: [0.2, 9.2, 5.8, 1.2 ] [4.6, -3.3, -0.2, -0.1 ] [-1.8, 0.2, -4.2, -3.9 ] [0, 0, 0, 1 ] I've had to go to various sources to get the little understanding of Collada I have and books about 3d transform matricies can get pretty intense. I've hit a brick wall and if you could please read through this and see if there is something I'm doing wrong, and how I'd go about getting an X,Y,Z to draw a point for each of these joints once I've calculated the final transform, I'd really appreciate it.

• Problem with SAT collision detection overlap checking code

  - by handyface

  I'm trying to implement a script that detects whether two rotated rectangles collide for my game, using SAT (Separating Axis Theorem). I used the method explained in the following article for my implementation in Google Dart. 2D Rotated Rectangle Collision I tried to implement this code into my game. Basically from what I understood was that I have two rectangles, these two rectangles can produce four axis (two per rectangle) by subtracting adjacent corner coordinates. Then all the corners from both rectangles need to be projected onto each axis, then multiplying the coordinates of the projection by the axis coordinates (point.x*axis.x+point.y*axis.y) to make a scalar value and checking whether the range of both the rectangle's projections overlap. When all the axis have overlapping projections, there's a collision. First of all, I'm wondering whether my comprehension about this algorithm is correct. If so I'd like to get some pointers in where my implementation (written in Dart, which is very readable for people comfortable with C-syntax) goes wrong. Thanks! EDIT: The question has been solved. For those interested in the working implementation: Click here

• Help with calculation to steer ship in 3d space

  - by Aaron Anodide

  I'm a beginner using XNA to try and make a 3D Asteroids game. I'm really close to having my space ship drive around as if it had thrusters for pitch and yaw. The problem is I can't quite figure out how to translate the rotations, for instance, when I pitch forward 45 degrees and then start to turn - in this case there should be rotation being applied to all three directions to get the "diagonal yaw" - right? I thought I had it right with the calculations below, but they cause a partly pitched forward ship to wobble instead of turn.... :( Here's current (almost working) calculations for the Rotation acceleration: float accel = .75f; // Thrust +Y / Forward if (currentKeyboardState.IsKeyDown(Keys.I)) { this.ship.AccelerationY += (float)Math.Cos(this.ship.RotationZ) * accel; this.ship.AccelerationX += (float)Math.Sin(this.ship.RotationZ) * -accel; this.ship.AccelerationZ += (float)Math.Sin(this.ship.RotationX) * accel; } // Rotation +Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.J)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * accel; } // Rotation -Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.K)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * -accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * -accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * -accel; } // Rotation +X / Pitch if (currentKeyboardState.IsKeyDown(Keys.F)) { this.ship.RotationAccelerationX += accel; } // Rotation -X / Pitch if (currentKeyboardState.IsKeyDown(Keys.D)) { this.ship.RotationAccelerationX -= accel; } I'm combining that with drawing code that does a rotation to the model: public void Draw(Matrix world, Matrix view, Matrix projection, TimeSpan elsapsedTime) { float seconds = (float)elsapsedTime.TotalSeconds; // update velocity based on acceleration this.VelocityX += this.AccelerationX * seconds; this.VelocityY += this.AccelerationY * seconds; this.VelocityZ += this.AccelerationZ * seconds; // update position based on velocity this.PositionX += this.VelocityX * seconds; this.PositionY += this.VelocityY * seconds; this.PositionZ += this.VelocityZ * seconds; // update rotational velocity based on rotational acceleration this.RotationVelocityX += this.RotationAccelerationX * seconds; this.RotationVelocityY += this.RotationAccelerationY * seconds; this.RotationVelocityZ += this.RotationAccelerationZ * seconds; // update rotation based on rotational velocity this.RotationX += this.RotationVelocityX * seconds; this.RotationY += this.RotationVelocityY * seconds; this.RotationZ += this.RotationVelocityZ * seconds; Matrix translation = Matrix.CreateTranslation(PositionX, PositionY, PositionZ); Matrix rotation = Matrix.CreateRotationX(RotationX) * Matrix.CreateRotationY(RotationY) * Matrix.CreateRotationZ(RotationZ); model.Root.Transform = rotation * translation * world; model.CopyAbsoluteBoneTransformsTo(boneTransforms); foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = boneTransforms[mesh.ParentBone.Index]; effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } mesh.Draw(); } }

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?

• How can I run and jump at the same time?

  - by Jan

  I'm having some trouble with the game I started. http://testing.fyrastudio.com/lab/tweetOlympics/v0.002/ The thing is that i have an athlete running and he must jump at the same time. A race with obstacles. I have him running (with pressing the letter Q repeateadly). I also have him jumping (with letter P) But the thing is that when he runs and jumps at the same time, he seems to be jumping at the same place, instead of going forward with the jump... any ideas how can I fix this?? This is the code I'm using for running and jumping on a continuos loop. //if accelearing and the last time that he accelerated was less than X seconds ago, hes running an accelaring if (athlete.accelerating && timeCurrent - athlete.last_acceleration > athlete.delay_acceleration) { athlete.accelerating = false; athlete.last_acceleration = timeCurrent; athlete.running = true; } if (!athlete.accelerating && timeCurrent - athlete.last_acceleration > athlete.delay_acceleration) { athlete.decelerating = true; } if(athlete.decelerating && timeCurrent - athlete.last_deceleration > athlete.delay_deceleration){ if(athlete.speed >= 1){ //athlete starts to decelarate athlete.last_deceleration = timeCurrent; athlete.decelerate(); }else { athlete.running = false; } } if (athlete.running) { athlete.position += athlete.speed; } if (athlete.jumping) { if (athlete.jump_height < 1) { athlete.jump_height = 1; }else { if (athlete.jump_height >= athlete.jump_max_height) { athlete.jump_height = athlete.jump_max_height; athlete.jumping = false; }else { athlete.jump_height = athlete.jump_height * athlete.jump_speed; } } } if (!athlete.jumping) { if(athlete.jump_height > 1){ athlete.jump_height = athlete.jump_height * 0.9; }else { athlete.jump_height = 1; } } athlete.scaleX = athlete.scaleY = athlete.jump_height; athlete.x = athlete.position; Thanks!

  How,can I disable coloring when texture is applied, because right now the texture is being colored over. foreach (BasicEffect effect in mesh.Effects) { effect.TextureEnabled = textureApplied; if(textureApplied) effect.Texture = Texture2D.FromStream(GraphicsDevice,System.IO.File.OpenRead(texturePath)); else { effect.DiffuseColor = ti.DiffuseColor; effect.EmissiveColor = ti.EmissiveColor; } ... } mesh.Draw(); Also, is there any easy way for xna to export models? Or do I have to write my own?

• 3D RTS pathfinding

  - by xcrypt

  I understand the A* algorithm, but I have some trouble doing it in 3D to suit the needs of my RTS Basically, in the game I'm making, there will be agents with different sizes of OBB collision boxes. I can use steering behaviours for avoiding other agents, so I don't need complete dynamic pathfinding. However, there is a problem because different agents have different collision geometry, and structures can be placed in almost any place. This means that there might be a gap between two structures where some agents can go through and some can't. A solution I have found to this problem is to do a sweep of the collision geometry of the agent from start node of the edge the pf algorithm is currently testing, to the end node of that edge. But this is probably a bit overkill since every edge the algorithm tests would also have to create and test with a collision geometry sweep. What are some reasonable approaches to this problem? I should mention that I'd prefer not to use navmeshes, I prefer waypoints because my entire system is based on it atm.

• How to synchronise the acceleration, velocity and position of the monsters on the server with the players?

  - by Nick

  I'm building an MMO using Node.js, and there are monsters roaming around. I can make them move around on the server using vector variables acceleration, velocity and position. acceleration = steeringForce / mass; velocity += acceleration * dTime; position += velocity * dTime; Right now I just send the positions over, and tell the players these are the "target positions" of the monsters, and let the monsters move towards the target positions on the client with a speed dependant on the distance of the target position. It works but looks rather strange. How do I synchronise these properly with the players without looking funny to them, taking into account the server lag? The problem is that I don't know how to make use of the correct acceleration/velocity values here; right now they just move directly in a straight line to the target position instead of accelerating/braking there properly. How can I implement such behaviour?

• Rotating wheel with touch (adding momentum and slowing down the initial rate it can be moved

  - by Lewis

  I have a wheel control in a game which is setup like so: - (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); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the momentum of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of momentum then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• First frame has a much longer delta time than other frames

  - by Kipras

  I had a problem where my AI moved extreme at the first frame and then normal after that. I then figured out it was my delta. It's about 0.016 seconds (60 fps), but the first frame was about 19000 seconds, which is obviously impossible. Does anybody know what might be happening? Also the delta later on likes to oscillate from 0.01 to 0.03, which is, again, crazy. long time = Sys.getTime() * 1000 / Sys.getTimerResolution(); float delta = (time - lastFrame) / 1000f; lastFrame = time; return delta; That's the delta code.

• Cloning a game and releasing the source

  - by Manux

  I'm not really aware of the legal issues surrounding game clones. I'm around halfway done of making a clone, but it's not just the same gaming concepts, I'm literally using the original game's files (which I do not intend to distribute in any way) in my clone. My original intention was to add features to the game (Firefly studios's first Stronghold) while still using the same art. Is it ok to distribute the source of my clone?

• Text on a model

  - by alecnash

  I am trying to put some text on a Model and I want it to be dynamic. Did some research and came up with drawing the text on the texture and then set it on the model. I use something like this: public static Texture2D SpriteFontTextToTexture(SpriteFont font, string text, Color backgroundColor, Color textColor) { Size = font.MeasureString(text); RenderTarget2D renderTarget = new RenderTarget2D(GraphicsDevice, (int)Size.X, (int)Size.Y); GraphicsDevice.SetRenderTarget(renderTarget); GraphicsDevice.Clear(Color.Transparent); Spritbatch.Begin(); //have to redo the ColorTexture Spritbatch.Draw(ColorTexture.Create(GraphicsDevice, 1024, 1024, backgroundColor), Vector2.Zero, Color.White); Spritbatch.DrawString(font, text, Vector2.Zero, textColor); Spritbatch.End(); GraphicsDevice.SetRenderTarget(null); return renderTarget; } When I was working with primitives and not models everything worked fine because I set the texture exactly where I wanted but with the model (RoundedRect 3D button). It now looks like that: Is there a way to have the text centered only on one side?

• Sorting for 2D Drawing

  - by Nexian

  okie, looked through quite a few similar questions but still feel the need to ask mine specifically (I know, crazy). Anyhoo: I am drawing a game in 2D (isometric) My objects have their own arrays. (i.e. Tiles[], Objects[], Particles[], etc) I want to have a draw[] array to hold anything that will be drawn. Because it is 2D, I assume I must prioritise depth over any other sorting or things will look weird. My game is turn based so Tiles and Objects won't be changing position every frame. However, Particles probably will. So I am thinking I can populate the draw[] array (probably a vector?) with what is on-screen and have it add/remove object, tile & particle references when I pan the screen or when a tile or object is specifically moved. No idea how often I'm going to have to update for particles right now. I want to do this because my game may have many thousands of objects and I want to iterate through as few as possible when drawing. I plan to give each element a depth value to sort by. So, my questions: Does the above method sound like a good way to deal with the actual drawing? What is the most efficient way to sort a vector? Most of the time it wont require efficiency. But for panning the screen it will. And I imagine if I have many particles on screen moving across multiple tiles, it may happen quite often. For reference, my screen will be drawing about 2,800 objects at any one time. When panning, it will be adding/removing about ~200 elements every second, and each new element will need adding in the correct location based on depth.

• Constrained A* problem

  - by Ragekit

  I've got a little problem with an A* algorithm that I need to Constrained a little bit. Basically : I use an A* to find the shortest path between 2 randomly placed room in 3D space, and then build a corridor between them. The problem I found is that sometimes it makes chimney like corridors that are not ideal, so I constrict the A* so that if the last movement was up or down, you go sideways. Everything is fine, but in some corner cases, it fails to find a path (when there is obviously one). Like here between the blue and red dot : (i'm in unity btw, but i don't think it matters) Here is the code of the actual A* (a bit long, and some redundency) while(current != goal) { //add stair up / stair down foreach(Node<GridUnit> test in current.Neighbors) { if(!test.Data.empty && test != goal) continue; //bug at arrival; if(test == goal && penul !=null) { Vector3 currentDiff = current.Data.bounds.center - test.Data.bounds.center; if(!Mathf.Approximately(currentDiff.y,0)) { //wanna drop on the last if(!coplanar(test.Data.bounds.center,current.Data.bounds.center,current.Data.parentUnit.bounds.center,to.Data.bounds.center)) { continue; } else { if(Mathf.Approximately(to.Data.bounds.center.x, current.Data.parentUnit.bounds.center.x) && Mathf.Approximately(to.Data.bounds.center.z, current.Data.parentUnit.bounds.center.z)) { continue; } } } } if(current.Data.parentUnit != null) { Vector3 previousDiff = current.Data.parentUnit.bounds.center - current.Data.bounds.center; Vector3 currentDiff = current.Data.bounds.center - test.Data.bounds.center; if(!Mathf.Approximately(previousDiff.y,0)) { if(!Mathf.Approximately(currentDiff.y,0)) { //you wanna drop now : continue; } if(current.Data.parentUnit.parentUnit != null) { if(!coplanar(test.Data.bounds.center,current.Data.bounds.center,current.Data.parentUnit.bounds.center,current.Data.parentUnit.parentUnit.bounds.center)) { continue; }else { if(Mathf.Approximately(test.Data.bounds.center.x, current.Data.parentUnit.parentUnit.bounds.center.x) && Mathf.Approximately(test.Data.bounds.center.z, current.Data.parentUnit.parentUnit.bounds.center.z)) { continue; } } } } } g = current.Data.g + HEURISTIC(current.Data,test.Data); h = HEURISTIC(test.Data,goal.Data); f = g + h; if(open.Contains(test) || closed.Contains(test)) { if(test.Data.f > f) { //found a shorter path going passing through that point test.Data.f = f; test.Data.g = g; test.Data.h = h; test.Data.parentUnit = current.Data; } } else { //jamais rencontré test.Data.f = f; test.Data.h = h; test.Data.g = g; test.Data.parentUnit = current.Data; open.Add(test); } } closed.Add (current); if(open.Count == 0) { Debug.Log("nothingfound"); //nothing more to test no path found, stay to from; List<GridUnit> r = new List<GridUnit>(); r.Add(from.Data); return r; } //sort open from small to biggest travel cost open.Sort(delegate(Node<GridUnit> x, Node<GridUnit> y) { return (int)(x.Data.f-y.Data.f); }); //get the smallest travel cost node; Node<GridUnit> smallest = open[0]; current = smallest; open.RemoveAt(0); } //build the path going backward; List<GridUnit> ret = new List<GridUnit>(); if(penul != null) { ret.Insert(0,to.Data); } GridUnit cur = goal.Data; ret.Insert(0,cur); do{ cur = cur.parentUnit; ret.Insert(0,cur); } while(cur != from.Data); return ret; You see at the start of the foreach i constrict the A* like i said. If you have any insight it would be cool. Thanks

• Data for animation

  - by saadtaame

  Say you are using C/SDL for a 2D game project. It's often the case that people use a structure to represent a frame in an animation. The struct consists of an image and how much time the frame is supposed to be visible. Is this data sufficient to represent somewhat complex animatio? Is it a good idea to separate animation management code and animation data? Can somebody provide a link to animations tutorials that store animations in a file and retrieve them when needed. I read this in a book (AI game programming wisdom) but would like to see a real implementation.

• Best approach to get clicked objects from a display list (2D)

  - by Ixx

  I'm implementing a display list to manage my visuals on screen. I want to know which object is clicked. My objects already have z-order variable. With my current knowledge (almost nothing) the only thing which comes to my mind is make a linear search and get all the objects which contains the clicked point. And then select the object with the highest z-order. But I know there are far better approaches. I think it's something with trees (binary search?). - container display objects and search recursively? just don't know where to start looking, for this concrete case. Any hint link or concrete solution is welcome.

• Material System

  - by Towelie

  I'm designing Material/Shader System (target API DX10+ and may be OpenGL3+, now only DX10). I know, there was a lot of topics about this, but i can't find what i need. I don't want to do some kind of compilation/parsing scripts in real-time. So there some artist-created material, written at some analog of CG. After it compiled to hlsl code and after to final shader. Also there are some hard-coded ConstantBuffers, like cbuffer EveryFrameChanging { float4x4 matView; float time; float delta; } And shader use shared constant buffers to get parameters. For each mesh in the scene, getting needs and what it can give (normals, binormals etc.) and finding corresponding permutation of shader or calculating missing parts. Also, during build calculating render states and the permutations or hash for this shader which later will be used for sorting or even giving the ID from 0 to ShaderCount w/o gaps to it for sorting. FinalShader have only 1 technique and one pass. After it for each Mesh setting some shader and it's good to render. some pseudo code SetConstantBuffer(ConstantBuffer::PerFrame); foreach (shader in FinalShaders) SetConstantBuffer(ConstantBuffer::PerShader, shader); SetRenderState(shader); foreach (mesh in shader.GetAllMeshes) SetConstantBuffer(ConstantBuffer::PerMesh, mesh); SetBuffers(mesh); Draw(); class FinalShader { public: UUID m_ID; RenderState m_RenderState; CBufferBindings m_BufferBindings; } But i have no idea how to create this CG language and do i really need it?

• Is it unprofessional to leave game resources to the open eye?

  - by ThePlan

  I'm still having problems packing my resources, after going through complicated APIs and basically just zip files which are exhausting my brain, I thought I could also pack the game with the resources visible to the human eye, in a simple folder. Would that be unprofessional? Personally, I've never even seen games do that, it would basically mean that the player could just edit whatever he wants in the game, like go in map1.txt and add an X somewhere to create a wall, or change the player sprite to a pony in MS PAINT.

• Unity: Render 2D textures on a 3D object's face

  - by www.Sillitoy.com

  I am not familiar with 3D graphics and I'd like to know what is the right way to render some 2D figures on different points of a wider face of a 3D object. My 3D object is just a cube representing a poker table. I have 2D png for players placeholders and I'd like to render these figures on the 3D object where needed. An alternative solution would be to render the whole face with a big picture containing all the placeholders figures. However it would be a waste of memory and thus less efficient. What do you suggest me?
