• Justin Terada Problems with Microsoft.DirectX SDK versions

  Hi, I'm trying to do the Coding4Fun Game Devlopment tutorial, but I can't seem to get it to work. I first tried it with the latest DirectX SDK (june 2006). But when I add the references to Mircosoft.DirectX and Microsoft.DirectX.Direct3D the Direct3D is version 1.0.2902.0 and the DirectX is version 2.0.0.0 This results in this error: The type 'Microsoft.DirectX.Direct3D.Device' exists in both 'c:\WINDOWS\Microsoft.NET\DirectX for Managed C ...Show All

• Veblen Lee Where is d3dim.lib, d3drm.lib, dsound3d.lib?

  My questions: 1) My book ("Tricks of the Windows Game Programming Gurus ed1" ) teaches DirectX 8.1 SDK. Is it fine to have that SDK on for ease-of-understanding w/ the book, or use the updated DirectX 9.0c SDK 2) Relating to DirectX 8.1 SDK, the book says I need the following library files: ddraw.lib dsound.lib dinput.lib dsetup.lib dplayx.lib Now, the next three are nowhere to be found in the library folder: d3dim.lib   d3drm.lib ds ...Show All

• sydes141 SampleFramework Camera

  I have a small problem with the sampleframework. I just create a world with one mesh and manipulate the view with the mouse / keyboard. Most works well, i.e. key movements, mouse wheel and the camera-movement with the right mousebutton. The problem is, that I can't move the world with the left mouse button. In onFrameMove there is the following code: camera.framemove(elapsedTime) device.transform.projection = camera.projectionmatrix device.trans ...Show All

  Hello, I've downloaded and installed C# Express 2005 and the Feb '06 DirectX SDK. I create a new project, add a reference to DirectX 2.0.0.0 but everytime I try to create a DirectInput keyboard it fails on the Aquire call. I've used the same code that everyone seems to recommend: keyb = new Microsoft.DirectX.DirectInput.Device(SystemGuid.Keyboard); keyb.SetCooperativeLevel(this, CooperativeLe ...Show All

• overpeer DirectSound issue: any help appreciated

  I realize this question is going fairly ambiguous, however the nature of the problem is somewhat similar. I'm developing the sound engine for a project, and the sound engine initially worked fine within the project. I took a break from the project, and when I came back the audio no longer played. Currently, when PlaySegmentEx is invoked, S_OK is returned... however absolutley no audio is audible. I am currently able to seperate the engine into i ...Show All

• JohnLx Question on ID3DXEffect::SetArrayRange

  Hi, I'm currently adding shader instancing to our engine. After I changed the single world matrix in the effect file to a matrix array, I noticed a heavy performance drop. The fps went down by almost 30%. After some investigation I found that the fps changes with the size of the matrix array, so the effect framework seems to always copy all elements of the array, not only those that were actually set. I then wanted to optimize this using the ID3 ...Show All

• garyl System.NullReferenceException was unhandled

  Hi! In my windowed control, whose rendering is done completely in Direct-x, I provide the means for the user to change the font. For this reason, my object includes the function SetupFont(), which is called at least once on startup to set the default font, and then it may be called whenever the user decides to change the font. The mobjFontDirectX and mobjFontGDI objects are defined at class level: private void SetupFont(System.Drawing.Fon ...Show All

• scott Hxxxx Distorted texture after lost/reset device

  Hi, I'm drawing a textured mesh using DrawIndexedPrimitive, using an effect interface. After a windowed/full screen toggle the texture appears distorted. Interestingly when I draw another mesh in wireframe mode in the same render call the problem doesn't occur. Can somebody help Nico It seems the DrawSubset function sets some state. That would explaine the strange behaviour. But I don't know exactly what it ...Show All

• 成工 Coping from a render target to a lockable texture

  I've built a GPU based particle system under Windows which works with the exception of one important part. I need to be able to build a bounding sphere off the particle positions. To do this I wrote a shader that samples nearby texels and finds the min/max and writes to a lower resolution texture (right now, the texture gets 4x smaller each pass) until the final size is < 2x2 texels. The idea would then be to copy that render target to ...Show All

• MEder Matching view to world - help!

  1. I have a number of meshes placed in world space. 2. Each mesh is being rendered using three vectors: scale, rotation and position. 3. I am calculating the world matrix with SCALE_VECTOR * ROTATION_VECTOR * POSITION_VECTOR . 4. One of these meshes represents the camera. So, when rendering this mesh I also set the view matrix. 5. The view matrix is calculated using LOOKATLH using the POSITION_VECTOR as the eye and POSITION_VECT ...Show All
