I'm working on a piece of code in C# / XNA where I'm highly concerned with performance. Part of this is passing several structs that are stored in arrays to various functions. Before this is asked, these are indeed supposed to be structs, not classes. They're essentially value types, and they need to (basically) live on the stack. Th...

Hello everyone. I am using Farseer and XNA. I'm trying to drag an body with the mouse, but I don't want a spring behavior, like in the demos.I want the object to follow the mouse very closely and without springiness, but still be able to rotate. I tried using another invisible body attached with a RevoluteJoint and moving that, but that...

Basically I want to be able to allocate unmanaged memory myself, ie. this piece of code should work: IntPtr ptr = Marshal.AllocHGlobal(10000)...
I am profiling my simple 2D XNA game. I found that 4% of entire running time is taken by simple operarion of adding together two Colors , one of them multiplied first by float. I need to call this method rogulthy 2000 times per frame (for each tile on map), which gave me 120000 times per second for XNA's 60 fps. Even minimal boosting of...

UPDATE 2: It now appears this is more of a modelling issue than a programming one. Whoops. I'm new to XNA development, and despite my C# experience, I've been stuck at one spot for going on two days now. The situation: I've created a model in 3D Studio Max 2010 which uses two materials, both are of type DirectX Shader. The model export...

It has been a long time since I touched 3D programming and I would like to start learning the new stuff that is currently going on. I would appreciate your help. Thank you. ...
I am writing simple hex engine for action-rpg in XNA 3.1. I want to light ground near hero and torches just as they were lighted in Diablo II. I though the best way to do so was to calculate field-of-view, hide any tiles and their's content that player can't see and draw special "Light" texture on top of any light source: Texture that is...

I'm programming a game in C# using the XNA3.1 engine. However I'm having a small issue with my camera, basically my camera tends to "flip" when it rotates more than 180 degrees on its roll (when the camera reaches 180 degrees, it seems to flip back to 0 degrees). The code for obtaining the view matrix is as follows: Globals.g_GameProces...
I essentially have a blank XNA project built using the XNA 3.1 wizard, i'm testing whether a game i make can be "installed" on another computer without having to make them install everything manually to make it work. The only additional code in the game is: Components.Add(new GamerServicesComponent(this)); After going through the Cli...
Hi, I want to prototype an idea for a game I have. The idea for this game is that the player will dig through the ground, creating tunnels and finding treasure. I'm looking to create 'worms style' terrain, with collision detection for the player wandering and jumping around the tunnels. Examples of this type of dynamic terrain can be se...
I am integrating with an application that uses plugins. I have my own plugin that is provided an HDC to draw on, this works fine using C# Graphics gfx = Graphics.FromHdc(hdc); I can then draw using GDI without issue. I would like to start experimenting with XNA, I've loaded a few sample projects and had a look through the code. It...
Hi all, I'm having a problem with the xna framework, I have a stripped down version of my code here to demonstrate. When the mouse is clicked an object is created at that mouse click point and the object is displayed via it's own draw method. What happens is that the first object is created at the correct position (current mouse coords...
