• Absorbtion 2d image effect

  - by Ed.

  I want to create a specyfic 2d image effect. It consists in modifying a sprite so it looks like it is being zoomed to a point or "absorbed" by that point. I'm not really sure what is the technical name of this effect so I cannot explain it correctly. Here you can see a video of what I'm talking about, it is the effect when the character absorbs the three glyphs. http://www.youtube.com/watch?v=PIo-GddsMcU&t=4m45s What is the name of this effect? How can I implement it with XNA for 2D textures/sprites?

• What happened to .fx files in D3D11?

  - by bobobobo

  It seems they completely ruined .fx file loading / parsing in D3D11. In D3D9, loading an entire effect file was D3DXCreateEffectFromFile( .. ), and you got a ID3DXEffect9, which had great methods like SetTechnique and BeginPass, making it easy to load and execute a shader with multiple techniques. Is this completely manual now in D3D11? The highest level functionality I can find is loading a SINGLE shader from an FX file using D3DX11CompileFromFile. Does anyone know if there's an easier way to load FX files and choose a technique? With the level of functionality provided in D3D11 now, it seems like you're better off just writing .hlsl files and forgetting about the whole idea of Techniques.

• Deferred Rendering With Diffuse,Specular, and Normal maps

  - by John

  I have been reading up on deferred rendering and I am trying to implement a renderer using the Sponza atrium model, which can be found here, as my sandbox.Note I am also using OpenGL 3.3 and GLSL. I am loading the model from a Wavefront OBJ file using Assimp. I extract all geometry information including tangents and bitangents. For all the aiMaterials,I extract the following information which essentially comes from the sponza.mtl file. Ambient/Diffuse/Specular/Emissive Reflectivity Coefficients(Ka,Kd,Ks,Ke) Shininess Diffuse Map Specular Map Normal Map I understand that I must render vertex attributes such as position ,normals,texture coordinates to textures as well as depth for the second render pass. A lot of resources mention putting colour information into a g-buffer in the initial render pass but do you not require the diffuse,specular and normal maps and therefore lights to determine the fragment colour? I know that doesnt make since sense because lighting should be done in the second render pass. In terms of normal mapping, do you essentially just pass the tangent,bitangents, and normals into g-buffers and then construct the tangent matrix and apply it to the sampled normal from the normal map. Ultimately, I would like to know how to incorporate this material information into my deferred renderer.

• (libgdx) Button doesn't work

  - by StercoreCode

  At the game I choose StopScreen. At this screen displays button. But if I click it - it doesn't work. What I expect - when I press button it must restart game. At this stage must display at least a message that the button is pressed. I tried to create new and clear project. Main class implement ApplicationListener. I put the same code in the appropriate methods. And it's works! But if i create this button in my game - it doesn't work. When i play and go to the StopScreen, i saw button. But if i click, or touch, nothing happens. I think that the proplem at the InputListener, although i set the stage as InputProcessor. Gdx.input.setInputProcessor(stage); I also try to addListener for Button as ClickListener. But it gave no results. Or it maybe problem that i implements Screen method - not ApplicationListener or Game. But if StopScreen implement ApplicationListener, at the mainGame I can't to setScreen. Just interests question: why button displays but nothing happens to it? Here is the code of StopScreen if it helps find my mistake: public class StopScreen implements Screen{ private OrthographicCamera camera; private SpriteBatch batch; public Stage stage; //** stage holds the Button **// private BitmapFont font; //** same as that used in Tut 7 **// private TextureAtlas buttonsAtlas; //** image of buttons **// private Skin buttonSkin; //** images are used as skins of the button **// public TextButton button; //** the button - the only actor in program **// public StopScreen(CurrusGame currusGame) { camera = new OrthographicCamera(); camera.setToOrtho(false, 800, 480); batch = new SpriteBatch(); buttonsAtlas = new TextureAtlas("button.pack"); //** button atlas image **// buttonSkin = new Skin(); buttonSkin.addRegions(buttonsAtlas); //** skins for on and off **// font = AssetLoader.font; //** font **// stage = new Stage(); stage.clear(); Gdx.input.setInputProcessor(stage); TextButton.TextButtonStyle style = new TextButton.TextButtonStyle(); style.up = buttonSkin.getDrawable("ButtonOff"); style.down = buttonSkin.getDrawable("ButtonOn"); style.font = font; button = new TextButton("PRESS ME", style); //** Button text and style **// button.setPosition(100, 100); //** Button location **// button.setHeight(100); //** Button Height **// button.setWidth(100); //** Button Width **// button.addListener(new InputListener() { public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) { Gdx.app.log("my app", "Pressed"); return true; } public void touchUp(InputEvent event, float x, float y, int pointer, int button) { Gdx.app.log("my app", "Released"); } }); stage.addActor(button); } @Override public void render(float delta) { Gdx.gl.glClearColor(0, 1, 0, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); stage.act(); batch.setProjectionMatrix(camera.combined); batch.begin(); stage.draw(); batch.end(); }

• Everything turning black when pitching down

  - by Gordon

  Just a quick questions about something that's occurring in my world. Every time I pitch my camera downward, everything starts turning black, and if I pitch upward, everything sort of intensifies. I'm multiplying my normals by the normal matrix in the shader, and I'm multiplying my lights direction by the model view matrix. If I leave the normal and light dir in world space everything ends up fine. I thought putting them both in view space would not cause those weird things to happen?

• OpenGL Learning Material (that's up to date)

  - by Sauron

  So im sure there are topics on this, but alot of them list older material. And the last book: http://www.amazon.com/OpenGL-SuperBible-Comprehensive-Tutorial-Reference/dp/0321712617/ref=sr_1_1?ie=UTF8&qid=1346116133&sr=8-1&keywords=opengl REALLY REALLY disappointed me. I DO NOT want to use someone else's library to learn this stuff, that bothers me SOOO much. So I was hoping there was a newer book that goes into detail, and doesn't use some sort of library "Hiding" everything from you. Or should I just look at older material? If so....anything thats not "too" out of date. Terrain tutorials are a plus (that's kinda my "goal"). Thanks

• Game engine design: Multiplayer and listen servers

  - by jarx

  My game engine right now consists of a working singleplayer part. I'm now starting to think about how to do the multiplayer part. I have found out that many games actually don't have a real singleplayer mode, but when playing alone you are actually hosting a local server as well, and almost everything runs as if you were in multiplayer (except that the data packets can be passed over an alternate route for better performance) My engine would need major refactoring to adapt to this model. There would be three possible modes: Dedicated client, Dedicated server and Client-Server (listen mode) * How often is the listen-server model used in the gaming industry? * What are the (dis)advantages of it? * What other options do I have?

• Implementing a FSM with ActionScript 2 without using classes?

  - by Up2u

  I have seen several references of A.I. and FSM, but sadly I still can't understand the point of an FSM in AS2.0. Is it a must to create a class for each state? I have a game-project which also it has an A.I., the A.I. has 3 states: distanceCheck, ChaseTarget, and Hit the target. It's an FPS game and played via mouse. I have created the A.I. successfully, but I want to convert it to FSM method... My first state is CheckDistanceState() and in that function I look for the nearest target and trigger the function ChaseState(), there I insert the Hit() function to destroy the enemy, The 3 functions that I created are being called in AI_cursor.onEnterframe. Is there any chance to implement an FSM without the need to create a class? From what I've read before, you have to create a class. I prefer to write the code on frames in flash and I still don't understand how to have external classes.

• Procedural world generation oriented on gameplay features

  - by Richard Fabian

  In large procedural landscape games, the land seems dull, but that's probably because the real world is largely dull, with only limited places where the scenery is dramatic or tactical. Looking at world generation from this point of view, a landscape generator for a game (that is, not for the sake of scenery, but for the sake of gameplay) needs to not follow the rules of landscaping, but instead some rules married to the expectations of the gamer. For example, there could be a choke point / route generator that creates hills ravines, rivers and mountains between cities, rather than the natural way cities arise, scattered on the land based on resources or conditions generated by the mountains and rainfall patterns. Is there any existing work being done like this? Start with cities or population centres and then add in terrain afterwards? The reason I'm asking is that I'd previously pondered taking existing maps from fantasy fiction (my own and others), putting the information into the system as a base point, and then generating a good world to play in from it. This seems covered by existing technology, that is, where the designer puts in all the necessary information such as the city populations, resources, biomes, road networks and rivers, then allows the PCG fill in the gaps. But now I'm wondering if it may be possible to have a content generator generate also the overall design. Generate the cities and population centres, balancing them so that there is a natural seeming need of commerce, then generate the positions and connectivity, then from the type of city produce the list of necessary resources that must be nearby, and only then, maybe given some rules on how to make the journey between cities both believable and interesting, generate the final content including the roads, the choke points, the bridges and tunnels, ferries and the terrain including the biomes and coastline necessary. If this has been done before, I'd like to know, and would like to know what went wrong, and what went right.

• Calculate gears rotation for a realtime simulation

  - by nkint

  Hi I'm trying to do a game with real time simulations of gears. There is a big Gear with inside a smaller gear. I managed to draw gears with different diameters but equal size teeth, but if i try to move the smaller one inside the bigger one the movement is odd. see the animated gif. the biggest gear is in center C1 and the small in the center C2. I calculate C2 position in this way: C2.x = C1.x + C1_RADIUS-C2_RADIUS) * cos(t); C2.y = C1.y - C1_RADIUS-C2_RADIUS) * sin(t); for t that goes from 0 to TWO_PI in n steps. I apply as rotation the angle t, but maybe it is wrong and i have to calculate another rotation for get a perfect joint

• Interactive Fiction engine and Tech Support - has anyone done this? [on hold]

  - by Larry G. Wapnitsky

  I've always been a big fan of Interactive Fiction and have been wanting to try my hand at it for a while. I have a need to create a decision tree for my tech support group (L1-L3) and feel as though presenting a decision tree in the form of an IF game would be rather interesting and helpful. I plan on using Inform7, but am curious if anyone has done anything like this in the past. If so, can you present examples, links to examples, opinions? Thanks, Larry

• How to effectively gather info about how players play my HTML5 game?

  - by Bane

  I'm finishing another HTML5 game, and this time I'd like to do some spying business on the players... Mostly just basic stuff: when they are playing, for how long, what upgrades they are buying the most and so on. Now, my first idea was just to collect this information during the gameplay, and then have a Javascript function fire when they close the tab/browser, and said function would send it to my server via Socket.io. This, of course, wouldn't work, because anyone who takes a look at the code would realize it and could start sending a tonne of false info which would mess up my statistics. Questions: Is there a way to effectively do this? If yes, what kind of info should I be looking for, aside from stuff I already mentioned?

• OpenGL ES 2 on Android: native window

  - by ThreaderSlash

  According to OGLES specification, we have the following definition: EGLSurface eglCreateWindowSurface(EGLDisplay display, EGLConfig config, NativeWindowType native_window, EGLint const * attrib_list) More details, here: http://www.khronos.org/opengles/documentation/opengles1_0/html/eglCreateWindowSurface.html And also by definition: int32_t ANativeWindow_setBuffersGeometry(ANativeWindow* window, int32_t width, int32_t height, int32_t format); More details, here: http://mobilepearls.com/labs/native-android-api I am running Android Native App on OGLES 2 and debugging it in a Samsung Nexus device. For setting up the 3D scene graph environment, the following variables are defined: struct android_app { ... ANativeWindow* window; }; android_app* mApplication; ... mApplication=&pApplication; And to initialize the App, we run the commands in the code: ANativeWindow_setBuffersGeometry(mApplication->window, 0, 0, lFormat); mSurface = eglCreateWindowSurface(mDisplay, lConfig, mApplication->window, NULL); Funny to say is that, the command ANativeWindow_setBuffersGeometry behaves as expected and works fine according to its definition, accepting all the parameters sent to it. But the eglCreateWindowSurface does no accept the parameter mApplication-window, as it should accept according to its definition. Instead, it looks for the following input: EGLNativeWindowType hWnd; mSurface = eglCreateWindowSurface(mDisplay,lConfig,hWnd,NULL); As an alternative, I considered to use instead: NativeWindowType hWnd=android_createDisplaySurface(); But debugger says: Function 'android_createDisplaySurface' could not be resolved Is 'android_createDisplaySurface' compatible only for OGLES 1 and not for OGLES 2? Can someone tell if there is a way to convert mApplication-window? In a way that the data from the android_app get accepted to the window surface?

• Where is a good spot to start when writing a LWJGL game engine?

  - by Alcionic

  I'm starting work on a huge game and somewhere along my train of thought I decided it would be a good idea to write my own engine for the game. I was originally going to use JMonkeyEngine but there were some things about it that just didn't work well with me. I wanted full control over every aspect of the entire process. Where would a good place to start be when writing your own engine? I have no experience with LWJGL but I learn quick. Either advice or some place where there is good advice would be nice. Thanks!

• XNA C# Rectangle Intersect Ball on a Square

  - by user2436057

  I made a Game like Peggle Deluxe using C# and XNA for lerning. I have 2 rectangles a ball and a square field. The ball gets shoot out with a cannon and if the Ball hits the Square the Square disapears and the Ball flys away.But the Ball doesent spring of realistically, it sometimes flys away in a different direction or gets stuck on the edge. Thads my Code at the moment: public void Update(Ball b, Deadline dl) { ArrayList listToDelete = new ArrayList(); foreach (Field aField in allFields) { if (aField.square.Intersects(b.ballhere)) { listToDelete.Add(aField); Punkte = Punkte + 100; float distanceX = Math.Abs(b.ballhere.X - aField.square.X); float distanceY = Math.Abs(b.ballhere.Y - aField.square.Y); if (distanceX < distanceY) { b.myMovement.X = -b.myMovement.X; } else { b.myMovement.Y = -b.myMovement.Y; } } } It changes the X or Y axis depending on how the ball hits the Square but not everytimes. What could cause the problem? Thanks for your answer. Greetings from Switzerland.

• OpenGL vs DirectX?

  - by Harold

  I saw the articles that were going on about OpenGL being better than DirectX and that Microsoft are really just trying to get everyone to use DirectX even though it's inferior so that gaming is almost exclusively for Windows and XBox, but since the article was written in 2006 is it still relevant today? Also I know plenty of games are written in DirectX but does anyone have any examples of popular games written in OpenGL? Thanks

• Direct2D Transform

  - by James

  I have a beginner question about Direct2D transforms. I have a 20 x 10 bitmap that I would like to draw in different orientations. To start, I would like to draw it vertically with a destination rectangle of say: (left, top, right, bottom) (300, 300, 310, 320) The bitmap is wider than it is tall (20 x 10), but when I draw it vertically, it will be appear taller than it is wide (10 x 20). I know that I can use a rotation matrix like so: m_pRenderTarget->SetTransform( D2D1::Matrix3x2F::Rotation( 90.0f, D2D1::Point2F(<center of shape>)) ); But when I use this method to rotate my shape, the destination rectangle is still wider than it is tall. Maybe it would look something like this: (left, top, right, bottom) (280, 290, 300, 300) The destination rectangle is 20 x 10 but the bitmap appears on the screen as 10 x 20. I can't look at the destination rectangle in the debugger and compare it to: (left, top, right, bottom) (300, 300, 310, 320) Is there any simple way to say "I want to rotate it so that the image is rendered to exactly this destination rectangle after the rotation?" In this case, I would like to say "Please rotate the bitmap so that it appears on the screen at this location:" (left, top, right, bottom) (300, 300, 310, 320) If I can't do that, is there any way to find out the 10 x 20 destination rectangle where the bitmap is actually being rendered to the screen?

• Newton Game Dynamics: Making an object not affect another object

  - by Boreal

  I'm going to be using Newton in my networked action game with Mogre. There will be two "types" of physics object: global and local. Global objects will be kept in sync for everybody; these include the players, projectiles, and other gameplay-related objects. Local objects are purely for effect, like ragdolls, debris, and particles. Is there a way to make the global objects affect the local objects without actually getting affected themselves? I'd like debris to bounce off of a tank, but I don't want the tank to respond in any way.

• How do I implement movement in a WPF Adventure game?

  - by ZeroPhase

  I'm working on making a short WPF adventure game. The only major hurdle I have right now is how to animate objects on the screen correctly. I've experimented with DoubleAnimation and ThicknessAnimation both enable movement of the character, but the speed is a bit erratic. The objects I'm trying to move around are labels in a grid, I'm checking the mouse's position in terms of the canvas I have the grid in. Does anyone have any suggestions for coding the movement, while still allowing mouse clicks to pick up items when needed? It would be nice if I could continue using the Visual Studio GUI Editor. By the way, I'm fine with scrapping labels in a grid for a more ideal object to manipulate. Here's my movement code: ThicknessAnimation ta = new ThicknessAnimation(); The event handling movement: private void Hansel_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { ta.FillBehavior = FillBehavior.HoldEnd; ta.From = Hansel.Margin; double newX = Mouse.GetPosition(PlayArea).X; double newY = Mouse.GetPosition(PlayArea).Y; if (newX < Convert.ToDouble(Hansel.Margin.Left)) { //newX = -1 * newX; ta.To = new Thickness(0, newY, newX, 0); } else if (newY < Convert.ToDouble(Hansel.Margin.Top)) { newY = -1 * newY; } else { ta.To = new Thickness(newX, newY, 0, 0); } ta.Duration = new Duration(TimeSpan.FromSeconds(2)); Hansel.BeginAnimation(Grid.MarginProperty, ta); } ScreenShot with annotations: http://i1118.photobucket.com/albums/k608/sealclubberr/clickToMove_zps9d4a33cc.png ScreenShot with example movement: http://i1118.photobucket.com/albums/k608/sealclubberr/clickToMove_zps51f2359f.jpg

• Why doesn't my cube hold a position?

  - by Christian Frantz

  I gave up a previous method of creating cubes so I went with a list to hold my cube objects. The list is being populated from an array like so: #region MAP float[,] map = { {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0}, {0, 0, 0, 0, 0} }; #endregion MAP for (int x = 0; x < mapWidth; x++) { for (int z = 0; z < mapHeight; z++) { cubes.Add(new Cube(device, new Vector3(x, map[x,z], z), Color.Green)); } } The cube follows all the parameters of what I had before. This is just easier to deal with. But when I debug, every cube has a position of (0, 0, 0) and there's just one black cube in the middle of my screen. What could I be doing wrong here? public Vector3 cubePosition { get; set; } public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Color color) { device = graphicsDevice; color = Color.Green; Position = cubePosition; SetUpIndices(); SetUpVerticesArray(); } That's the cube constructor. All variables are being passed correctly I think

• 2D Grid based game - how should I draw grid lines?

  - by Adam K Dean

  I'm playing around with a 2D grid based game idea, and I am using sprites for the grid cells. Let's say there is a 10 x 10 grid and each cell is 48x48, which will have sprites drawn there. That is fine. But in design mode, I'd like to have a grid overlay the screen. I can do this either with sprites (2x600 pixel image etc) or with primitives, but which is best? Should I really be switching between sprites and 3d/2d rendering? Like so: Thanks!

• How do I render only part of a texture to a point sprite in OpenGL ES for Android?

  - by nbolton

  Using the libgdx framework, I've figured out how to render a texture to a point sprite. The problem is, it renders the entire texture to the point sprite, where I only want a small part of it (since it's an isometric tile image). Here's a snippet from some demo code I wrote... create() { renderer = new ImmediateModeRenderer(); tiles = Gdx.graphics.newTexture( Gdx.files.internal("data/tiles2.png"), TextureFilter.MipMap, TextureFilter.Linear, TextureWrap.ClampToEdge, TextureWrap.ClampToEdge); Gdx.gl.glClearColor(0.6f, 0.7f, 0.9f, 1); Gdx.gl.glEnable(GL10.GL_TEXTURE_2D); Gdx.gl.glEnable(GL11.GL_POINT_SPRITE_OES); Gdx.gl11.glTexEnvi( GL11.GL_POINT_SPRITE_OES, GL11.GL_COORD_REPLACE_OES, GL11.GL_TRUE); Gdx.gl10.glPointSize(s); tiles.bind(); } render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); renderer.begin(GL10.GL_POINTS); // render 3 point sprites at various 3d points renderer.vertex(-.1f, 0, -.1f); renderer.vertex(0, 0, 0); renderer.vertex(.1f, 0, .1f); // ... more vertices here if needed (one for each sprite) ... renderer.end(); }

• XNA Moddable Game - Architecture Design and Reflection

  - by David K

  I've decided to embark on an XNA moddable game project of a simple rogue style. For all purposes of this question, I'm going to not be using a scripting engine, but rather allow modders to directly compile assemblies that are loaded by the game at run time. I know about the security problems this may raise. So in order to expose the moddable content, I have gone about creating a generic project in XNA called MyModel. This contains a number of interfaces that all inherit from IPlugin, such as IGameSystem, IRenderingSystem, IHud, IInputSystem etc. Then I've created another project called MyRogueModel. This references MyModel project, and holds interfaces such as IMonster, IPlayer, IDungeonGenerator, IInventorySystem. More rogue specific interfaces, but again, all interfaces in this project inherit from IPlugin. Then finally, I've created another project called MyRogueGame, that references both MyModel and MyRogueModel projects. This project will be the game that you run and play. Here I have put the actual implementation of the Monster, DungeonGenerator, InputSystem and RenderingSystem classes. This project will also scan the mods directory during run time and load any IPlugins it finds using reflection and override anything it finds from the default. For example if it finds a new implementation of the DungeonGenerator it will use that one instead. Now my question is, in order to get this far, I have effectively 2 projects that contain nothing but interfaces... which seems a little... strange ? For people to create mods for the game, I would give them both the MyModel and MyRogueModel assemblies in which they would reference. I'm not sure whether this is the right way to do it, but my reasoning goes as follows : If I write 1 input system, I can use it in any game I write. If I create 3 rogue like games, and a modder writes 1 rendering system, that modder could use the rendering system for all 3 games, because it all comes from the MyModel project. I come from a more web based C# role, so having empty interface projects doesn't seem wrong, its just something I haven't done before. Before I embark on something that might be crazy, I'd just like to know whether this is a foolish idea and whether there's a better (or established) design principle I should be following ?

• 3D Model not translating correctly (visually)

  - by ChocoMan

  In my first image, my model displays correctly: But when I move the model's position along the Z-axis (forward) I get this, yet the Y-axis doesnt change. An if I keep going, the model disappears into the ground: Any suggestions as to how I can get the model to translate properly visually? Here is how Im calling the model and the terrain in draw(): cameraPosition = new Vector3(camX, camY, camZ); // Copy any parent transforms. Matrix[] transforms = new Matrix[mShockwave.Bones.Count]; mShockwave.CopyAbsoluteBoneTransformsTo(transforms); Matrix[] ttransforms = new Matrix[terrain.Bones.Count]; terrain.CopyAbsoluteBoneTransformsTo(ttransforms); // Draw the model. A model can have multiple meshes, so loop. foreach (ModelMesh mesh in mShockwave.Meshes) { // This is where the mesh orientation is set, as well // as our camera and projection. foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.PreferPerPixelLighting = true; effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateRotationY(modelRotation) * Matrix.CreateTranslation(modelPosition); // Looking at the model (picture shouldnt change other than rotation) effect.View = Matrix.CreateLookAt(cameraPosition, modelPosition, Vector3.Up); effect.Projection = Matrix.CreatePerspectiveFieldOfView( MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 10000.0f); effect.TextureEnabled = true; } // Draw the mesh, using the effects set above. prepare3d(); mesh.Draw(); } //Terrain test foreach (ModelMesh meshT in terrain.Meshes) { foreach (BasicEffect effect in meshT.Effects) { effect.EnableDefaultLighting(); effect.PreferPerPixelLighting = true; effect.World = ttransforms[meshT.ParentBone.Index] * Matrix.CreateRotationY(0) * Matrix.CreateTranslation(terrainPosition); // Looking at the model (picture shouldnt change other than rotation) effect.View = Matrix.CreateLookAt(cameraPosition, terrainPosition, Vector3.Up); effect.Projection = Matrix.CreatePerspectiveFieldOfView( MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 10000.0f); effect.TextureEnabled = true; } // Draw the mesh, using the effects set above. prepare3d(); meshT.Draw(); DrawText(); } base.Draw(gameTime); } Im suspecting that there may be something wrong with how I'm handling my camera. The model rotates fine on its Y-axis.
