• Jim Wooley How I get the index array from a model?

  I load a model from file into XNA and I want to store the data for modifying the vertex and adding some vertices and make some other transformations, like grouping all the small models in one single vertex buffer and index buffer and making a basic collision detector with walls. I have followed the issue and I found this topic http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=891302&SiteID=1 Ok, It wasn’t easy, but finally I can manage to get the vertex of the models. But when I try to get the data from the index buffer I get this error "You cannot call GetData on a resource that was created with ResourceUsage.WriteOnly." And the ResourceUsage prop ...Show All

• Elder Morales Multi-core programming

  Will the XNA Framework allow assigning threads to specific cores on the 360 Or more generally, how will XNA Framework interact with the 360's cores and hardware threads Yes, we are providing the ability to assign a Thread to a specific core and hardware thread. Wouldn't that be rather 360 specific In the regular .net framework you can set affinity and priority on a thread, isn't that sufficient Or does the XNA framework introduce a new way of dealing with threads Does the lock and volatile keyword work the same on the 360 Thanks, Roger Larsen twospoons wrote: So basically you need different code blocks for different platforms.

• Littletommy Microsoft.XNA.Framework.Curve

  Hi, I was wondering if anyone had looked at or used the Curve Class yet. I am having difficulty working out how to use it, perhap anyone could shed any light. I was thinking initially that it is a beizer curve type class, but I can't see co-ordinate information for the control points. All I can see is that CurveKeys have a value and a posistion, presumably between 0-1. Is the value the "y" position on a graph and the x is the position. Has anyone any more information that I can read in to determine what to use a curve for. Kind Regards, Paul Kinlan www.kinlan.co.uk Hi Paul. I think the position is like the x coord and the value is like the y coord on a 2D cartesian system (I've haven't tried it yet, ...Show All

• SteveLK Need help with 2D sprite animation using C++

  So far, my program is very simple, I have only drawn a sprite using a texture interface and moving it in the my game loop with 4 keyboard keys: W, A, S &D.  But I'm already getting lag and inconsistent animation(just movement in this case) rate: 1.  If I try to move the sprite in the one direction, it will start out very slow, and then speeds up to a constant pace.  Then if I let go of that key and hit anther key to head towards the other direction it will again start at a slow pace in the first 2 seconds then gets faster afterwards.  2.  At different times, the sprite will move in the same direction at different speed: sometimes faster and a few times slower.  Since I increase/de ...Show All

• D-- Mysterious EffectMaterial Error...

  I am trying to draw an x-file, specifically the skybox01.x file included with the DirectX SDK, using XNA. The Code: foreach (ModelMesh mesh in Skybox.Meshes) { //This is where it Crashes, on the next line. foreach (BasicEffect effect in mesh.Effects) { //Effect Settings Goes here } //Draw the mesh, will use the effects set above. mesh.Draw(); } The Error: Unable to cast object of type 'Microsoft.Xna.Framework.Content.EffectMaterial' to type 'Microsoft.Xna.Framework.Graphics.BasicEffect'. I know why it crashes, since what is inside the meshes.Effects is a EffectMaterial and not a basic effect... But how to fix it I have not a clue. I have all 3 files for dra ...Show All

• MSNetDeveloper New XNA Competition?

  Anyone know (and willing to talk about if you do) this Whoever is behind it is hiding using DomainsByProxy.com. January isn't that far off, so I expect more details soon. Guess I'll just get my main game ready and see what happens. Sweet, thanks! Guess I'd better get cracking! Well, I actually have something in the works that I couldn't get done for the 360homebrew contest due to other committments, but this looks cool! You'd better believe I'll be checking sites several times a day (not that I don't already, but... ) Well, not all day. Oh, and what are you doing !

• shades921 Local orientation?

  Hello, I'm used to translating objects by their local orientation. How would i go about doing so in XNA I tried getting Quaternions to work, but to no success. I looked at the Spacewar demo as well, but in that demo they change x/y velocities depending on the current rotation of the object, which isnt a very clean way to go about things in my opinion. Ok, this is how you make a model move forward in the direction it is facing if you press w, and turn left/right if you press a/d. This uses only matrix/quaternion math. First, initialize your variables: Matrix world = Matrix.Identity; Matrix translation = Matrix.CreateTranslation(0,0,0); Quaternion rotation = Quaternion.CreateFromAxisAngle(Vector3. ...Show All

• Bruxir XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All
