  • Separating logic and data in browser game

    - by Tesserex
    I've been thinking this over for days and I'm still not sure what to do. I'm trying to refactor a combat system in PHP (...sorry.) Here's what exists so far: There are two (so far) types of entities that can participate in combat. Let's just call them players and NPCs. Their data is already written pretty well. When involved in combat, these entities are wrapped with another object in the DB called a Combatant, which gives them information about the particular fight. They can be involved in multiple combats at once. I'm trying to write the logic engine for combat by having combatants injected into it. I want to be able to mock everything for testing. In order to separate logic and data, I want to have two interfaces / base classes, one being ICombatantData and the other ICombatantLogic. The two implementers of data will be one for the real objects stored in the database, and the other for my mock objects. I'm now running into uncertainties with designing the logic side of things. I can have one implementer for each of players and NPCs, but then I have an issue. A combatant needs to be able to return the entity that it wraps. Should this getter method be part of logic or data? I feel strongly that it should be in data, because the logic part is used for executing combat, and won't be available if someone is just looking up information about an upcoming fight. But the data classes only separate mock from DB, not player from NPC. If I try having two child classes of the DB data implementer, one for each entity type, then how do I architect that while keeping my mocks in the loop? Do I need some third interface like IEntityProvider that I inject into the data classes? Also with some of the ideas I've been considering, I feel like I'll have to put checks in place to make sure you don't mismatch things, like making the logic for an NPC accidentally wrap the data for a player. Does that make any sense? Is that a situation that would even be possible if the architecture is correct, or would the right design prohibit that completely so I don't need to check for it? If someone could help me just layout a class diagram or something for this it would help me a lot. Thanks. edit Also useful to note, the mock data class doesn't really need the Entity, since I'll just be specifying all the parameters like combat stats directly instead. So maybe that will affect the correct design.

  • Rotating a Quad around it center

    - by Trixmix
    How can you rotate a quad around its center? This is what im trying to do but it aint working: GL11.glTranslatef(x-getWidth()/2, y-getHeight()/2, 0); GL11.glRotatef(30, 0.0f, 0.0f, 1.0f); GL11.glTranslatef(x+getWidth()/2, y+getHeight()/2, 0); DRAW my main problem is that it renders it off the screen.. draw code: GL11.glBegin(GL11.GL_QUADS); { GL11.glTexCoord2f(0, 0); GL11.glVertex2f(0, 0); GL11.glTexCoord2f(0, getTexture().getHeight()); GL11.glVertex2f(0, height); GL11.glTexCoord2f(getTexture().getWidth(), getTexture().getHeight()); GL11.glVertex2f(width,height); GL11.glTexCoord2f(getTexture().getWidth(), 0); GL11.glVertex2f(width,0); } GL11.glEnd();

  • How to implement time traveling into a game?

    - by Billy
    I was wondering how to implement time travel into a game. Nothing super complex, just time-reversal like what's in Braid, where the user can rewind/fast forward time by 30 seconds or whatever. I searched around the web a lot, but my results usually referred to using time as in like "it's 3:00" or a timer and such. The only thing I could think of was using 2 arrays, one for the player's x position and the other for the player's y position, and then iterating through those arrays and placing the character at that position as they rewind/fast forward time. Could that work? If it would work, how large would the array have to be and how often should I store the player's x and y? If it doesn't work, what else could I try? Thanks in advance!

  • Do I need the 'w' component in my Vector class?

    - by bobobobo
    Assume you're writing matrix code that handles rotation, translation etc for 3d space. Now the transformation matrices have to be 4x4 to fit the translation component in. However, you don't actually need to store a w component in the vector do you? Even in perspective division, you can simply compute and store w outside of the vector, and perspective divide before returning from the method. For example: // post multiply vec2=matrix*vector Vector operator*( const Matrix & a, const Vector& v ) { Vector r ; // do matrix mult r.x = a._11*v.x + a._12*v.y ... real w = a._41*v.x + a._42*v.y ... // perspective divide r /= w ; return r ; } Is there a point in storing w in the Vector class?

  • Android loading screens blocking, good practice?

    - by Oren
    I've noticed many (if not all) android games don't support the "back" button functionality during their loading screens. Which leads to some frustrating moments when a user accidentally starts up the game and has to wait for the long loading stage to end in order to close it. So my questions are: 1) Why is that ? Is there a good reason to avoid something like asynchronous loading (or some other solution to this problem) in android games ? 2) If there is no good reason not to support this functionality, what would be the best way to accomplish it ?

  • jump pads problem

    - by Pasquale Sada
    I'm trying to make a character jump on a landing pad who stays above him. Here is the formula I've used (everything is pretty much self-explainable, maybe except character_MaxForce that is the total force the character can jump ): deltaPosition = target - character_position; sqrtTerm = Sqrt(2*-gravity.y * deltaPosition.y + MaxYVelocity* character_MaxForce); time = (MaxYVelocity-sqrtTerm) /gravity.y; speedSq = jumpVelocity.x* jumpVelocity.x + jumpVelocity.z *jumpVelocity.z; if speedSq < (character_MaxForce * character_MaxForce) we have the right time so we can store the value jumpVelocity.x = deltaPosition.x / time; jumpVelocity.z = deltaPosition.z / time; otherwise we try the other solution time = (MaxYVelocity+sqrtTerm) /gravity.y; and then store it jumpVelocity.x = deltaPosition.x / time; jumpVelocity.z = deltaPosition.z / time; jumpVelocity.y = MaxYVelocity; rigidbody_velocity = jumpVelocity; The problem is that the character is jumping away from the landing pad or sometime he jumps too far never hitting the landing pad.

  • Generating and rendering not point-like particles on GPU

    - by TravisG
    Specifically I'm talking about particles as seen (for example) in the UE4 dev video here. They're not just points and seem to have a nice shape to them that seems to follow their movement. Is it possible to create these kinds of particles (efficiently) completely on the GPU (perhaps through something like motion? Or is the only (or most efficient) way to just create a small particle texture and render small quads for each particle?

  • Figuring out what object is closer to a certain point?

    - by user1157885
    I'm trying to create fog of war, I have the visual effect created but I'm not sure how to deal with the hiding of other players if they're within the fog of war. So right now the thing I'm trying to do is if another player is hiding behind a wall then not to render that player. I was thinking of doing it by sending a ray in the direction of all the players, and then creating a list of all the obstacles that ray collides with and then trying to figure out if an obstacle was closer than the player in order to predict the distance. But then I realized I'm not really sure how to figure out if the obstacle is infact closer or not because I have to account for all the dimensions, so I'm kind of stuck. First of all is this approach the correct way to go about it and secondly how would I calculate if the obstacle was infact closer taking into account the X Y and Z. Thanks

  • Box2Dweb very slow on node.js

    - by Peteris
    I'm using Box2Dweb on node.js. I have a rotated box object that I apply an impulse to move around. The timestep is set at 50ms, however, it bumps up to 100ms and even 200ms as soon as I add any more edges or boxes. Here are the edges I would like to use as bounds around the playing area: // Computing the corners var upLeft = new b2Vec2(0, 0), lowLeft = new b2Vec2(0, height), lowRight = new b2Vec2(width, height), upRight = new b2Vec2(width, 0) // Edges bounding the visible game area var edgeFixDef = new b2FixtureDef edgeFixDef.friction = 0.5 edgeFixDef.restitution = 0.2 edgeFixDef.shape = new b2PolygonShape var edgeBodyDef = new b2BodyDef; edgeBodyDef.type = b2Body.b2_staticBody edgeFixDef.shape.SetAsEdge(upLeft, lowLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowLeft, lowRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(lowRight, upRight) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) edgeFixDef.shape.SetAsEdge(upRight, upLeft) world.CreateBody(edgeBodyDef).CreateFixture(edgeFixDef) Can box2d really become this slow for even two bodies or is there some pitfall? It would be very surprising given all the demos which successfully use tens of objects.

  • Models from 3ds max lose their transformations when input into XNA

    - by jacobian
    I am making models in 3ds max. However when I export them to .fbx format and then input them into XNA, they lose their scaling. -It is most likely something to do with not using the transforms from the model correctly, is the following code correct -using xna 3.0 Matrix[] transforms=new Matrix[playerModel.Meshes.Count]; playerModel.CopyAbsoluteBoneTransformsTo(transforms); // Draw the model. int count = 0; foreach (ModelMesh mesh in playerModel.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = transforms[count]* Matrix.CreateScale(scale) * Matrix.CreateRotationX((float)MathHelper.ToRadians(rx)) * Matrix.CreateRotationY((float)MathHelper.ToRadians(ry)) * Matrix.CreateRotationZ((float)MathHelper.ToRadians(rz))* Matrix.CreateTranslation(position); effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } count++; mesh.Draw(); }

  • Can Google Translate's audio files be used in a game?

    - by ashes999
    For my game, I need text-to-speech. Since it's Android, I decided to settle for MP3s, since the range of words spoken is few. For my prototype, I'm using Google Translate to generate the audio since it has awesome pronounciation across multiple languages. But can I use it in production? What if I sell my game for $1 on the app store? All I can find on SE is that the API may be LGPL, and that the licensing page mentions the API is only available for academic research -- nothing more. My usage is a bit different; I'm actually capturing the audio bits and using those instead. I'm curious to know the license for this; I can't find anything with my Google-fu.

  • XNA GameTime TotalGameTime slower than real time

    - by robasaurus
    I have set-up an empty test project consisting of a System.Diagnostics.Stopwatch and this in the draw method: spriteBatch.DrawString(font, gameTime.TotalGameTime.TotalSeconds.ToString(), new Vector2(100, 100), Color.White); spriteBatch.DrawString(font, stopwatch.Elapsed.TotalSeconds.ToString(), new Vector2(100, 200), Color.White); The GameTime.TotalGameTime displayed is slower than the stop watch (by about 5 seconds per minute) even though GameTime.IsRunningSlowly is always false, why is this? The reason this is an issue is because I have a server which uses stopwatch and it is faster than my client game. For instance my client notifies the server it has dropped a mine which explodes in one minute. Because the stopwatch is faster the server state explodes the mine before the client and they are out of sync. I don't want to have to notify the client when the server explodes it as this would use unnecessary bandwidth.

  • What is the recommended way to output values to FBO targets? (OpenGL 3.3 + GLSL 330)

    - by datSilencer
    I'll begin by apologizing for any dumb assumptions you might find in the code below since I'm still pretty much green when it comes to OpenGL programming. I'm currently trying to implement deferred shading by using FBO's and their associated targets (textures in my case). I have a simple (I think :P) geometry+fragment shader program and I'd like to write its Fragment Shader stage output to three different render targets (previously bound by a call to glDrawBuffers()), like so: #version 330 in vec3 WorldPos0; in vec2 TexCoord0; in vec3 Normal0; in vec3 Tangent0; layout(location = 0) out vec3 WorldPos; layout(location = 1) out vec3 Diffuse; layout(location = 2) out vec3 Normal; uniform sampler2D gColorMap; uniform sampler2D gNormalMap; vec3 CalcBumpedNormal() { vec3 Normal = normalize(Normal0); vec3 Tangent = normalize(Tangent0); Tangent = normalize(Tangent - dot(Tangent, Normal) * Normal); vec3 Bitangent = cross(Tangent, Normal); vec3 BumpMapNormal = texture(gNormalMap, TexCoord0).xyz; BumpMapNormal = 2 * BumpMapNormal - vec3(1.0, 1.0, -1.0); vec3 NewNormal; mat3 TBN = mat3(Tangent, Bitangent, Normal); NewNormal = TBN * BumpMapNormal; NewNormal = normalize(NewNormal); return NewNormal; } void main() { WorldPos = WorldPos0; Diffuse = texture(gColorMap, TexCoord0).xyz; Normal = CalcBumpedNormal(); } If my render target textures are configured as: RT1:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE0, GL_COLOR_ATTACHMENT0) RT2:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE1, GL_COLOR_ATTACHMENT1) RT3:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE2, GL_COLOR_ATTACHMENT2) And assuming that each texture has an internal format capable of contaning the incoming data, will the fragment shader write the corresponding values to the expected texture targets? On a related note, do the textures need to be bound to the OpenGL context when they are Multiple Render Targets? From some Googling, I think there are two other ways to output to MRTs: 1: Output each component to gl_FragData[n]. Some forum posts say this method is deprecated. However, looking at the latest OpenGL 3.3 and 4.0 specifications at opengl.org, the core profiles still mention this approach. 2: Use a typed output array variable for the expected type. In this case, I think it would be something like this: out vec3 [3] output; void main() { output[0] = WorldPos0; output[1] = texture(gColorMap, TexCoord0).xyz; output[2] = CalcBumpedNormal(); } So which is then the recommended approach? Is there a recommended approach at all if I plan to code on top of OpenGL 3.3? Thanks for your time and help!

  • What are the semantics of glRotate and glTranslate's parameters?

    - by Zarkopafilis
    I have been trying to play with OpenGL after watching some tutorials and I don't understand how the glTranslatef and glRotatef functions work. I believe a simple picture would help me. I understand that glTranslatef changes the position of the "camera" (but does it change the position in wich the shapes are getting drawn)? However, I don't understand the rotation concept at all. If I do glRotatef(1,0,0,1) it makes my quad spin around. If I just do glRotatef(1,0,0,0) it makes the quad smaller (further away) but if I try to rotate around the X or Y axis, I get a black screen. I don't understand the angle either. Help would be appreciated.

  • How to divide hex grid evenly among n players?

    - by manabreak
    I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

  • Is it better to cut and store all sprites needed from a spritesheet in memory, or cut them out just-in-time?

    - by xLite
    I'm not sure what's best practice here as I have little experience with this. Essentially what I am asking is... if it's better to get your single PNG with all your different sprites on it for use in-game, cut out every sprite on startup and store them in memory, then access the already-cut-out sprite from memory quickly or Only have the single PNG with all the different sprites residing in memory, and when you need, for example, a tree. You cut out the tree from the PNG and then continue to use it as normal. I imagine the former is more CPU friendly than the latter but less memory friendly, vice versa for the latter. I want to know what the norm is for game dev. This is a pixel based game using 2D art. Each PNG is actually an avatar's sprite sheet with each body part separated and then later joined to form the full body of the avatar.

  • As a indie, how to protect your game?

    - by user16829
    As a indie, you might not work in a company. And you may have a great game idea and you feel it gonna be a big success. When you released your game. How do you protect it as your own creation? So that someone also can't steal the title and publish a "sequel" e.g. Your-Game-Name 2,3,4. Or even produce by-products like Angry Birds but without your permission. So how we can prevent these from happening by legal methods. Like copyrights, trademarks? If a professional can fill us those info, it will be great.

  • Slopes in 2D Platformer

    - by Carlosrdz1
    I'm dealing with Slopes in a 2D platformer game I'm developing in XNA Game Studio. I was really tired of trying without success, until I found this post: 45° Slopes in a Tile based 2D platformer, and I solved part of the problem with the bummzack answer. Now I'm dealing with 2 more problems: 1) Inverted slopes: The post says: If you're only dealing with 45 degree angles, then it gets even simpler: y1 = y + (x1 - x) If the slope is the other way round, it's: y1 = y + (v - (x1 - x)) My question is, what if I'm dealing with slopes with less than 45 degree angles? Does y1 = y + (v - (x1 - x)) work? 2) Going down the slope: I can't find a better way to handle the "going down through the slope" situation, considering that my player can accelerate its velocity. Edit: I was about to post a image but I guess I need to have more reputation he he he... What I'm trying to say with "going down" is like walking towards the opposite direction, assuming that if you are walking to the right, you are incrementing your Y position because you are climbing the slope, but if you are walking to the left, you are decrementing your Y position.

  • Pseudo-magnet implementation with chipmunk

    - by Eimantas
    How should I go about implementing "natural" magnet on a certain body in chipmunk space? Context is of simple bodies lying in the space (think chessboard). When one of the figures is activated as a magnet - others should start moving towards it. Currently I'm applying force (cpBodyApplyForce)to the other figures with vector calculated towards the activated figure. However this doesn't really feel "natural". Are there any known algorithms for imitating magnets?

  • Easy road from DisplayObject to Molehill?

    - by Bart van Heukelom
    I have a finished Flash game which is rendered using the built-in display tree, i.e. Bitmaps contained in Sprites (and a text here and there, few vector graphics, and one bitmap-filled shape). For extra performance, I'd like it to use Molehill for rendering, but that's not possible out of the box. What's the easiest way to make this game use Molehill when available, but fall back to the current method if it's not available?

  • Why are my scene's depth values not being written to my DepthStencilView?

    - by dotminic
    I'm rendering to a depth map in order to use it as a shader resource view, but when I sample the depth map in my shader, the red component has a value of 1 while all other channels have a value of 0. The Texture2D I use to create the DepthStencilView is bound with the D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE flags, the DepthStencilView has the DXGI_FORMAT_D32_FLOAT format, and the ShaderResourceView's format is D3D11_SRV_DIMENSION_TEXTURE2D. I'm setting the depth map render target, then i'm drawing my scene, and once that is done, I'm the back buffer render target and depth stencil are set on the output merger, and I'm using the depth map shader resource view as a texture in my shader, but the depth value in the red channel is constantly 1. I'm not getting any runtime errors from D3D, and no compile time warning or anything. I'm not sure what I'm missing here at all. I have the impression the depth value is always being set to 1. I have not set any depth/stencil states, and AFAICT depth writing is enabled by default. The geometry is being rendered correctly so I'm pretty sure depth writing is enabled. The device is created with the appropriate debug flags; #if defined(DEBUG) || defined(_DEBUG) deviceFlags |= D3D11_CREATE_DEVICE_DEBUG | D3D11_RLDO_DETAIL; #endif This is how I create my depth map. I've omitted error checking for the sake of brevity D3D11_TEXTURE2D_DESC td; td.Width = width; td.Height = height; td.MipLevels = 1; td.ArraySize = 1; td.Format = DXGI_FORMAT_R32_TYPELESS; td.SampleDesc.Count = 1; td.SampleDesc.Quality = 0; td.Usage = D3D11_USAGE_DEFAULT; td.BindFlags = D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE; td.CPUAccessFlags = 0; td.MiscFlags = 0; _device->CreateTexture2D(&texDesc, 0, &this->_depthMap); D3D11_DEPTH_STENCIL_VIEW_DESC dsvd; ZeroMemory(&dsvd, sizeof(dsvd)); dsvd.Format = DXGI_FORMAT_D32_FLOAT; dsvd.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2D; dsvd.Texture2D.MipSlice = 0; _device->CreateDepthStencilView(this->_depthMap, &dsvd, &this->_dmapDSV); D3D11_SHADER_RESOURCE_VIEW_DESC srvd; srvd.Format = DXGI_FORMAT_R32_FLOAT; srvd.ViewDimension = D3D11_SRV_DIMENSION_TEXTURE2D; srvd.Texture2D.MipLevels = texDesc.MipLevels; srvd.Texture2D.MostDetailedMip = 0; _device->CreateShaderResourceView(this->_depthMap, &srvd, &this->_dmapSRV);

  • How can I get my first-person character in Unity to move to a ledge with an animation?

    - by BallzOfSteel
    I'm trying to get this to happen: The character walks up to a large crate, the player presses a button, and an animation starts playing where the character climbs up on to the crate. (all in first person view). So far I tried this with normal "First Person Controller" Prefab in Unity. My code so far: function OnTriggerStay(other : Collider){ if(other.tag == "GrabZone"){ if(Input.GetKeyDown("e")){ animation.Play("JumpToLedge"); } } } However when i use this on The FPC it will always play from the position the animation is created on. I also tried to create an empty game object, placing the FPC in there. Gives same effect. I also tried just animating the graphics of the FPC alone. This seems to work but since the Character Controller itself is not animated that stays onthe ground. So the whole FPC wont work anymore. Is there anyway i could let this animation play on the local position the player is on at that time? Or can you think of any other logical solution for a grab and climb?

  • Unity , libgdx, or something else to develop my first game for Android?

    - by capcom
    I want to start by saying that I absolutely love Unity (even more when I team it up with Blender). I really want to start developing games for Android, but it seems like Unity poses way too many roadblocks in terms of which devices it supports (and even if it does support them, it doesn't work well on all of them). I've been looking around for alternatives, and found something called libgdx. Well, it's nothing like Unity unfortunately, but at least it seems like I may be able to reach a larger audience in the market. I'd like to start by making 2D games, but with 3D graphics (say, imported from Blender). I can do this very easily in Unity, and it seems like it should be alright with libgdx too. But I really want to know if ditching Unity is a smart idea, considering how comfortable I am with it already, and how much I like it. Finally, is libgdx something you would recommend considering my requirements/situation? BTW, I am quite familiar with Eclipse too. Many thanks. Feel free to request further details.

  • Drawing Grid in 3D view - Mathematically calculate points and draw line between them (Not working)

    - by Deukalion
    I'm trying to draw a simple grid from a starting point and expand it to a size. Doing this mathematically and drawing the lines between each point, but since the "DrawPrimitives(LineList)" doesn't work the way it should work, And this method can't even draw lines between four points to create a simple Rectangle, so how does this method work exactly? Some sort of coordinate system: [ ][ ][ ][ ][ ][ ][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.0][ ][0.0][ ][2.0][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][ ][ ][ ][ ][ ][ ] I've checked with my method and it's working as it should. It calculates all the points to form a grid. This way I should be able to create Points where to draw line right? This way, if I supply the method with Size = 2 it starts at 0,0 and works it through all the corners (2,2) on each side. So, I have the positions of each point. How do I draw lines between these? VerticeCount = must be number of Points in this case, right? So, tell me, if I can't supply this method with Point A, Point B, Point C, Point D to draw a four vertice rectangle (Point A - B - C - D) - how do I do it? How do I even begin to understand it? As far as I'm concered, that's a "Line list" or a list of points where to draw lines. Can anyone explain what I'm missing? I wish to do this mathematically so I can create a a custom grid that can be altered.

  • How can I locate the frames of a spritesheet PNG based on this PLIST data?

    - by kitsune
    Someone asked me to reskin a certain game. Now he only sent me the whole sprite PNG and PLIST files of the sprites. He instructed me to rename each sprite with the same name corresponding to each original sprite. The problem is, he gave me the whole sprite sheet instead of each individual sprite and the PLIST. Now yes, I can read the PNG filenames from the PLIST, but I cannot rename the reskin sprites I did because I'm not sure which sprite is boy_gun_3_3.png; there are multiple guns, I don't know which is which. Is there a way to extract individual accurately named individual PNG files from the single sprite sheet using the PLIST?
