  • Crash when using datablocks

    - by scorcher24
    I have really throughly searched the net and could not find any solution for this so I ask for help here. Anyway, I have this datablock in datablocks.cs: datablock t2dSceneObjectDatablock(EnemyShipConfig) { canSaveDynamicFields = "1"; Layer = "3"; size = "64 64"; CollisionActiveSend = "1"; CollisionActiveReceive = "1"; CollisionCallback = true; CollisionLayers = "3"; CollisionDetectionMode = "POLYGON"; CollisionPolyList = "0.00 -0.791 0.756 0.751 -0.746 0.732"; UsesPhysics = "0"; Rotation = "-90"; WorldLimitMode = "KILL"; WorldLimitMax = "880 360"; WorldLimitMin = "-765 -436"; minFireRate = "2000"; maxFireRate = "1200"; laserSpeed = "800"; minSpeed = "100"; maxSpeed = "150"; }; This is an exact reproduction of an object that I have manually edited in the editor. So far, I just used clone() to get as many enemies as I need, while it was out of sight. It is a r-type style shooter, so I need a variable amount of enemies. Since clone() spams my log, I decided to use datablocks, since it is also more flexible. That's what I get when I use clone(): Con::execute - 0 has no namespace: onRemoveFromScene However, once spawning begins, my game freezes and crashes: function SpawnEnemy() { //%spawnedEnemy = EnemyShipMaster.clone(true); %spawnedEnemy = new t2dStaticSprite() { class = "EnemyShip"; sceneGraph = $global_sceneGraph; datablock = "EnemyShipConfig"; imageMap = "starshipImageMap"; layer = 3; }; %speed = getRandom(%spawnedEnemy.minSpeed, %spawnedEnemy.maxSpeed); %y = getRandom(-320, 320); // Set Properties %spawnedEnemy.setPositionX(700); %spawnedEnemy.setPositionY(%y); %spawnedEnemy.setVisible(true); %spawnedEnemy.setLinearVelocityX( -%speed ); %spawnedEnemy.setTimerOn( getRandom( %spawnedEnemy.maxFireRate, %spawnedEnemy.minFireRate ) ); } // Definition of $global_sceneGraph from game.cs: $global_sceneGraph = sceneWindow2D.loadLevel(%level); As I said, it works fine when I use clone() (which is commented out here), but my log gets spammed. I really hope someone can shed some light for me, this is driving me crazy.

  • How do I implement input and movement with characters that get into vehicles?

    - by Xkynar
    I'm making a game similar to GTA2. When the player enters the vehicle, what happens in terms of logic? Does the player becomes the vehicle? Does the vehicle override the player movement? The main question is how should it look at a vehicle? I want to understand if the player becomes the car or if the player has a "motion state" like "driving, walking, flying" depending on what he is doing in a moment, I know there are tons of ways to implement vehicles in a game.

  • Deep Cloning C++ class that inherits CCNode in Cocos2dx

    - by A Devanney
    I stuck with something in Cocos2dx ... I'm trying to deep clone one of my classes that inherits CCNode. Basically i have.... GameItem* pTemp = new GameItem(*_actualItem); // loops through all the blocks in gameitem and updates their position pTemp->moveDown(); // if in boundary or collision etc... if (_gameBoard->isValidMove(pTemp)) { _actualItem = pTemp; // display the position CCLog("pos (1) --- (X : %d,Y : %d)", _actualItem->getGridX(),_actualItem->getGridY()); } Then doesn't work, because the gameitem inherits CCNode and has the collection of another class that also inherits CCNode. its just creating a shallow copy and when you look at children of the gameitem node in the copy, just point to the original? class GameItem : public CCNode { // maps to the actual grid position of the shape CCPoint* _rawPosition; // tracks the current grid position int _gridX, _gridY; // tracks the change if the item has moved CCPoint _offset; public: //constructors GameItem& operator=(const GameItem& item); GameItem(Shape shape); ... } then in the implementation.... GameItem& GameItem::operator=(const GameItem& item) { _gridX = item.getGridX(); _gridY = item.getGridY(); _offset = item.getOffSet(); _rawPosition = item.getRawPosition(); // how do i copy the node? return *this; } // shape contains an array of position for the game character GameItem::GameItem(Shape shape) { _rawPosition = shape.getShapePositions(); //loop through all blocks in position for (int i = 0; i < 7; i++) { // get the position of the first block in the shape and add to the position of the first block int x = (int) (getRawPosition()[i].x + getGridX()); int y = (int) (getRawPosition()[i].y + getGridY()); //instantiate a block with the position and type Block* block = Block::blockWithFile(x,y,(i+1), shape); // add the block to the this node this->addChild(block); } } And for clarity here is the block class class Block : public CCNode{ private: // using composition over inheritance CCSprite* _sprite; // tracks the current grid position int _gridX, _gridY; // used to store actual image number int _blockNo; public: Block(void); Block(int gridX, int gridY, int blockNo); Block& operator=(const Block& block); // static constructor for the creation of a block static Block* blockWithFile(int gridX, int gridY,int blockNo, Shape shape); ... } The blocks implementation..... Block& Block::operator=(const Block& block) { _sprite = new CCSprite(*block._sprite); _gridX = block._gridX; _gridY = block._gridY; _blockNo = block._blockNo; //again how to clone CCNode? return *this; } Block* Block::blockWithFile(int gridX, int gridY,int blockNo, Shape shape) { Block* block = new Block(); if (block && block->initBlockWithFile(gridX, gridY,blockNo, shape)) { block->autorelease(); return block; } CC_SAFE_DELETE(block); return NULL; } bool Block::initBlockWithFile(int gridX, int gridY,int blockNo, Shape shape) { setGridX(gridX); setGridY(gridY); setBlockNo(blockNo); const char* characterImg = helperFunctions::Format(shape.getFileName(),blockNo); // add to the spritesheet CCTexture2D* gameArtTexture = CCTextureCache::sharedTextureCache()->addImage("Character.pvr.ccz"); CCSpriteBatchNode::createWithTexture(gameArtTexture); // block settings _sprite = CCSprite::createWithSpriteFrameName(characterImg); // set the position of the block and add it to the layer this->setPosition(CONVERTGRIDTOACTUALPOS_X_Y(gridX,gridY)); this->addChild(_sprite); return true; } Any ideas are welcome at this point!! thanks

  • Is it possible to programmatically prevent a game from pausing when its window loses focus?

    - by user836045
    I'm playing Skyrim in windowed mode and I am trying to create a bot for this game for personal use. I would like to have the bot play the game in the background, while I do other things, the only problem is that the game window pauses when it loses focus. Is there a way to make the Skyrim process think that it still has the focus, so it continues to run while I do something else on another window? I'm not a windows programming expert but would this be possible if I could somehow intercept the message that says unfocused or minimized to the process, and thus let the process think its still focused? I think Skyrim uses directx, so is it possible to come up with a solution from that end?

  • Complex shading using one single (small) texture

    - by teodron
    Recently I stumbled upon a demo reel in UDK about how one can attain beautiful results using just one (rather tiny) texture that's being sent to the shader pipeline. The famous link is this one. Basically, the author states that they've used just one texture and give a snapshot of the technique here. I see that every RGBA channel contains different grayscale information.. and that info could be used to inside a shader to obtain a colour blended output. The problem is that the reel displays a fairly complex scene. To top that, the author even makes use of a normal map. How did they manage to fit a normal map in an already cluttered texture? It makes sense to have a half-space normal map by using only RG from an RGB texture, but what about the rest of the information? Since it was proven to be possible, could someone please explain how it was done (the big picture, not the dirty details!)!? Here's the texture being used. Click to see in full size.

  • More smaller maps among which player can travel

    - by davidv
    I am developing 2d game, where maps are tile based, small about 20x20 tiles and player can travel between a lot of maps (in my game rooms) like this. The maps are connected sometimes verticaly and sometimes horizontaly and together they make one big cave. Should I create a class where one 2d array holds all the maps (another 2d arrays), or is there any other way? Whats the most efficient way to create them in this class? Thank you for your help.

  • Problem when texturing triangles using glVertexPointer()

    - by tigrou
    I'm having a problem for displaying a single quad, here is how i do : float tex_coord[] = { 0.0, 0.0, 0.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 0.0, 0.0, 0.0 }; //how many coords should i give ? int indexes[] = { 3, 2, 0, 0, 1, 3 } float vertexes[] = { -37, 0, 30, -38, 0, 29, -41, 0, 32, -42, 0, 31 } glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vertexes); glTexCoordPointer(2, GL_FLOAT, 0, tex_coord); glDrawElements(GL_TRIANGLES, 2, GL_UNSIGNED_INT, indices); glDisableClientState(GL_VERTEX_ARRAY); glDisableClientState(GL_TEXTURE_COORD_ARRAY); The result : (with 2 triangles) (with 4 triangles)

  • Which API for cross platform mobile audio?

    - by deft_code
    This question focuses on the API's available on phones. I'd been planning to use OpenAL in my game for maximum portability. It runs great on Linux so I can quickly develop the Game and leverage it's superior debugging tools. However I've recently heard that Android doesn't support OpenAL well. Instead they've gone with a OpenSL ES library. What I'm looking for is a free Audio library that I can use with minimal custom code on iPhone, Android, and my Linux desktop. Does such an API exists? Some extra details: The game is written in C++ with custom minimal front ends. ObjC for iPhone, Java for Android, and SFML for Desktops. I'm using OpenGL ES for portability as iPhone doesn't support the more advanced OpenGL APIs.

  • how to calculate intersection time and place of multiple moving arcs

    - by user20733
    I have rocks orbiting moons, moons orbiting planets, planets orbiting suns, and suns orbiting black holes, and the current system could have many many layers of orbitage. the position of any object is a function of time and relative to the object it orbits. (so far so good). now I want to know for a given 2 objects(A,B), a start time and a speed, how can I work out the when and where to go. I can work out where A and B is given a time. so i just need. 1: direction to travel in from A to B(remember B is moving(not in a straight line)) 2: Time to get to b in a straight line. travel must be in a straight line with the shortest possible distance. as an extension to this question, how will i know if its better to wait, EG is it faster to stay on object A and wait for a hour when the objects may be closer, than to set off from A to B at the start. Cheers, it hurt my brain.

  • Using ImpactJS: How to set a publicly available variable

    - by Dave Voyles
    I'm trying to get an entity (a bullet, a grenade, and an explosive) from my player player. Specifically, I want the shootingRate of my bullet (how frequently it can be fired). How can I do this without having to call getEntityByType each time I fire this projectile? There has got to be a cleaner way from what I'm doing right now.... // Shooting var isShooting = ig.input.state('shoot'); if (isShooting && this.lastShootTimer.delta() > 0) { switch (this.activeWeapon) { case("EntityBullet"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y - 10); var equipedWeap = ig.game.getEntitiesByType(EntityBullet); this.lastShootTimer.set(equippedWeap.shootingRate); console.log(equipedWeap.shootingRate); break; case("EntityGrenade"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y +5); var equipedWeap = ig.game.getEntitiesByType(EntityGrenade); this.lastShootTimer.set(equipedWeap.shootingRate); console.log(EquipedWeap.shootingRate); break; case("EntityExplosiveBomb"): ig.game.spawnEntity(this.activeWeapon, this.pos.x, this.pos.y +5 ); var equipedWeap = ig.game.getEntitiesByType(EntityExplosiveBomb)[0]; this.lastShootTimer.set(equipedWeap.shootingRate); console.log(equipedWeap.shootingRate); break; } }

  • Now that Device Central is dead, how can I test my Flash Lite applications?

    - by Kirby
    I'm trying to use Flash Lite to make a simple game for my girlfriend, who only has a Nokia 5530, but I just realized in CS6 Adobe killed Device Central, so there's no way for me to test it without the device (and it's supposed to be a surprise). Is there any other way for me to test it? I know I can just export the movie and use Flash Player, but Device Central allowed me to test drag and drop and memory/processor usage for example... tl;dr, is there an alternative to Device Central for testing Flash Lite in older devices?

  • XNA 4 game for both profiles

    - by Vodácek
    I am writing game in XNA 4 and this version have two profiles hi-def and reach. My problem is that I need to have my game code for each of these profiles and is very uncomfortable to have two projects and do all changes in both of them. My idea was to use preprocessor directive (i am not sure about name of this, http://msdn.microsoft.com/en-us/library/ed8yd1ha%28v=vs.71%29.aspx) and use IF statement at places with problems with profile. There is only problem that program needs to be compiled two times (for each profile) and manually changed directive and project settings to another profile. And my questions are: Is that good way? Is there better and cleaner way how to do this?

  • Complete Beginner to Game Programming and Unreal Engine 4, Looking For Advice [on hold]

    - by onemic
    I am currently a 2nd year programming student(Just finished my first year so I will be starting my second year in September) and have mainly learned C and C++ in my classes. In terms of what I know of C++, I know about general inheritance, polymorphism, overloading operators, iterators, a little bit about templates(only class and function templates) etc. but not of the more advanced topics like linked lists and other sequential containers(containers in general I guess), enumerations, most of the standard library(other than like strings and vectors), and probably a bunch of other stuff I dont even know about yet. I subscribed to Unreal Engine 4 as I was very intrigued by their Unreal Tournament announcement earlier this month, especially after hearing that UE4 is going completely C++. Of course my end goal in doing this programming program is to eventually go into game/graphics programming. Since it's my summer off, I thought what better way then to actually apply some of my skills to a personal project so I actually have a firmer understanding of C++ past what my professors tell me. My questions are this: What would be the best way to start off making a small personal game in UE4 as a project for the summer? What should I be aiming for, especially for someone that is still learning C++? Should I focus on making a simple 2D game rather than a 3D one to get started? Seeing the Flappy Chicken showcase intrigued me because before I thought the UE engine was pretty much pigeonholed into being for FPS games What should my expectations be going into UE4 and a game engine for the first time?(UE4 will be my first foray into making a game) What can I expect to gain from making things in UE4, in terms of making games and in terms of further fleshing out my knowledge of C++? Would you recommend I start off 100% using C++ for scripting or using the visual blueprints? Since I'm not a designer, how would I be able to add objects and designs to my game? For someone at my level is retaining the UE4 subscription worth it or is it better to cancel and resub when I learn enough about UE4 and C++? Lastly is there anything to be gained in terms of knowledge/insight through me looking at the source code for UE4? I opened it in VS2013, but noticed that most of the files were C# files and not cpp's. Thanks in advance for taking the time to answer.

  • What's the difference between a "Release" Xbox 360 build and a "Debug" one?

    - by Sebastian Gray
    I've got a build of my game that works on Windows under a release and debug build as expected. When I deploy the debug version of the game to the Xbox, it works as expected and runs the same as on Windows - however when I deploy the release version to the XBOX I get different behaviour within the game. I'm using a 3rd party library for the collisions (which is where I am seeing differences between the release and debug versions of my game); so I can't see what's actually different but I suspect they have some compiler directive for Debug on the Xbox to the Release version on the Xbox. As such, I'm thinking that I may need to release my game with the Debug build instead of the Release build but I want to know what issues I can expect by doing so? Are there any significant performance issues between the two build profiles?

  • I don't understand why one of my vbo is overwritten by another

    - by Alays
    to create a vbo I use this function: public void loadVBO(){ vboID = GL15.glGenBuffers(); GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, vboID); GL15.glBufferData(GL15.GL_ARRAY_BUFFER, buf, GL15.GL_STATIC_DRAW); // Put the position coordinates in attribute list 0 GL20.glVertexAttribPointer(0, 4, GL11.GL_FLOAT, false,4*4+4*4+4*4+2*4 , 0); // Put the color components in attribute list 1 GL20.glVertexAttribPointer(1, 4, GL11.GL_FLOAT, false,4*4+4*4+4*4+2*4 , 4*4); GL20.glVertexAttribPointer(2, 4, GL11.GL_FLOAT, false,4*4+4*4+4*4+2*4 , 4*4+4*4); // Put the texture coordinates in attribute list 2 GL20.glVertexAttribPointer(3, 4, GL11.GL_FLOAT, false,4*4+4*4+4*4+2*4 , 4*4+4*4+4*4); GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0); } to display a vbo I use this function: public void displayVBO(){ GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, vboID); GL20.glEnableVertexAttribArray(0); GL20.glEnableVertexAttribArray(1); GL20.glEnableVertexAttribArray(2); GL20.glEnableVertexAttribArray(3); GL11.glDrawArrays(GL_TRIANGLES, 0, buf.capacity()); GL20.glDisableVertexAttribArray(0); GL20.glDisableVertexAttribArray(1); GL20.glDisableVertexAttribArray(2); GL20.glDisableVertexAttribArray(3); GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0); } So when I call map.loadVBO() and then ocean.loadVBO(), I think the second call overwrite the first vbo I don't know how ... When I call map.display() and ocean.display(), I have the ocean draw 2 times .... Thanks.

  • Double Buffering in Panda3D (C++)

    - by jsvcycling
    How would I go about using Double Buffering (to create a loading screen) in Panda3D using C++? I've searched Google and found some forums that talk about the concept of swapping buffers, but I haven't seen any that show any type of source code (specifically Panda3D/C++). I'd like to try and stay away from using pure OpenGL code and work it through Panda3D, but if I have no other choice, then I'll have to go with OpenGL coding.

  • What is this type of sound effect called?

    - by Fibericon
    There is a sound typically associated with a bright flash of light, which starts with a lower whirring noise, then breaks into a higher pitched sound. What is that type of sound called? I'm not sure how to begin searching for that, so a typical name for it would be very helpful. It's something similar to what occurs at 0:41 in this youtube video (here's a link to a few seconds beforehand), where Naruto 6 tails transforms into Kyuubei in Naruto Generations.

  • How are OpenGL ES 1 framebuffers and textures sized?

    - by jens
    I am trying to draw to a texture using a framebuffer using OpenGL ES 1.1 on Android, Java. Afterwords I want to overlay this texture full-screen over my game. In theory, this works like a charm, but somehow the coordinates are off. For testing I drew something at (0,0) with width and height 200, and it partly is off-screen. This is how I create the framebuffer: fb = new int[1]; depthRb = new int[1]; renderTex = new int[1]; gl11ep.glGenFramebuffersOES(1, fb, 0); gl11ep.glGenRenderbuffersOES(1, depthRb, 0); // the depth buffer gl.glGenTextures(1, renderTex, 0);// generate texture gl.glBindTexture(GL10.GL_TEXTURE_2D, renderTex[0]); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT); texBuffer = ByteBuffer.allocateDirect(buf.length*4).order(ByteOrder.nativeOrder()).asIntBuffer(); gl.glTexImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_LUMINANCE, texW, texH, 0, GL10.GL_LUMINANCE, GL10.GL_UNSIGNED_BYTE, texBuffer); gl11ep.glBindRenderbufferOES(GL11ExtensionPack.GL_RENDERBUFFER_OES, depthRb[0]); gl11ep.glRenderbufferStorageOES(GL11ExtensionPack.GL_RENDERBUFFER_OES, GL11ExtensionPack.GL_DEPTH_COMPONENT16, texW, texH); Before I draw, I do this: gl11ep.glBindFramebufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, fb[0]); gl.glClearColor(0f, 0f, 0f, 0f); // specify texture as color attachment gl11ep.glFramebufferTexture2DOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, GL11ExtensionPack.GL_COLOR_ATTACHMENT0_OES, GL10.GL_TEXTURE_2D, renderTex[0], 0); // attach render buffer as depth buffer gl11ep.glFramebufferRenderbufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, GL11ExtensionPack.GL_DEPTH_ATTACHMENT_OES, GL11ExtensionPack.GL_RENDERBUFFER_OES, depthRb[0]); I set texW = 1024 and texH = 512. When rendering this texture fullscreen, with a lightmask (size 200x200) placed at (0, 0) and (texW/2, texH/2). You can see that it seems like the coordinate system doesnt start at (0,0) as that light overlaps the screen and the images are not drawn as squares (my lightcone-texture is a circle, not an ellipse). So, how is the coordinate system of this offscreen-drawn texture defined? Thanks

  • Memory is full with vertex buffer

    - by Christian Frantz
    I'm having a pretty strange problem that I didn't think I'd run into. I was able to store a 50x50 grid in one vertex buffer finally, in hopes of better performance. Before I had each cube have an individual vertex buffer and with 4 50x50 grids, this slowed down my game tremendously. But it still ran. With 4 50x50 grids with my new code, that's only 4 vertex buffers. With the 4 vertex buffers, I get a memory error. When I load the game with 1 grid, it takes forever to load and with my previous version, it started up right away. So I don't know if I'm storing chunks wrong or what but it stumped me -.- for (int x = 0; x < 50; x++) { for (int z = 0; z < 50; z++) { for (int y = 0; y <= map[x, z]; y++) { SetUpVertices(); SetUpIndices(); cubes.Add(new Cube(device, new Vector3(x, map[x, z] - y, z), grass)); } } } vertexBuffer = new VertexBuffer(device, typeof(VertexPositionTexture), vertices.Count(), BufferUsage.WriteOnly); vertexBuffer.SetData<VertexPositionTexture>(vertices.ToArray()); indexBuffer = new IndexBuffer(device, typeof(short), indices.Count(), BufferUsage.WriteOnly); indexBuffer.SetData(indices.ToArray()); Thats how theyre stored. The array I'm reading from is a byte array which defines the coordinates of my map. Now with my old version, I used the same loading from an array so that hasn't changed. The only difference is the one vertex buffer instead of 2500 for a 50x50 grid. cubes is just a normal list that holds all my cubes for the vertex buffer. Another thing that just came to mind would be my draw calls. If I'm setting an effect for each cube in my cube list, that's probably going to take a lot of memory. How can I avoid doing this? I need the foreach method to set my cubes to the right position foreach (Cube block in cube.cubes) { effect.VertexColorEnabled = false; effect.TextureEnabled = true; Matrix center = Matrix.CreateTranslation(new Vector3(-0.5f, -0.5f, -0.5f)); Matrix scale = Matrix.CreateScale(1f); Matrix translate = Matrix.CreateTranslation(block.cubePosition); effect.World = center * scale * translate; effect.View = cam.view; effect.Projection = cam.proj; effect.FogEnabled = false; effect.FogColor = Color.CornflowerBlue.ToVector3(); effect.FogStart = 1.0f; effect.FogEnd = 50.0f; cube.Draw(effect); noc++; }

  • How to make game menu Java

    - by Deathsbreed
    I've been searching all over for how to make a game menu, but I haven't found anything useful. I have a very simple Pong like game (source-code here), and I want to add a main menu to it. This wouldn't be too much of a problem if I was making a standalone with JFrame instead of an Applet, but I want this to be available on the web (not downloaded). I might have been able to do some of it myself, except for the fact that it would mean having a very heavy main class (in this case the GNP.java file). So I was thinking, is there a way to basically have a Java Applet and have it use a JFrame and how? and if not, what could I do? Thanks!

  • Need an engine for MMO mockup

    - by Kayle
    What I don't need is an MMORPG engine, at the moment. What I do need is a flexible easy-to-use engine that I can make a mock-up with. I don't need support for more than 10 players in an instance, so any multiplayer platform is probably fine. I need an engine with which I can create the following core features: Waves of simple AI enemies that have specific objectives (move to point A, destroy target, move to point B). The units present can be between 50-200 in number. An over-the-shoulder view and the ability to control a team of 3 (like Mass Effect or the latest Dragon Age) Functioning inventory system Right now, all I can really think of is Unreal or Source. Any other suggestions? Again, this is a proving mock-up, not an actual MMO. I'm not terribly worried about the visual aspects as we just want to test mechanics. Note: Can write some scripts in Python, Ruby, or Lua, if necessary.

  • Java getResourceAsStream as local resource

    - by Dajgoro Labinac
    Before using LWJGL, I used the Graphic method, and there I displayed imageicons, and I had the picture file located in the resources. I used: ImageIcon tcard = new ImageIcon(this.getClass().getResource("RCA.png")); to load the image. Now when I load textures in LWJGL, I have to use absolute paths to locate the file: tcard = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("C:/RCA.png")); I tried Googling, but I didn't find anything helpful. How can I load the image from the local resources like in the first example?

  • In what kind of variable type is the player position stored on a MMORPG such as WoW?

    - by jokoon
    I even heard J. Carmack quickly talk about it... How a software can track a player's position so accurately, being on a such huge world, without loading between zones, and on a multiplayer scale ? How is the data formatted when it passes through the netcode ? I can understand how vertices are stored into the graphic card's memory, but when it comes to synchronize the multiplayer, I can't imagine what is best.
