[quote user="n00bz0rd2"]Hey. I'm working on an RTS game in XNA 3.0 and have gotten quite far with it, but I don't know how to move my models over the terriain (heightmap) by mouse clicks. I had a look at the Ziggyware tutorial, but it was not 3D and of no use. I was wondering if anyone had any good tutorials or could even help me ...

The Actor approach you describe is fine in most situations. Hardware instancing is only useful for a situation where you want to draw very large amounts of very few different kinds of low-poly models. It is especially unsuited for complicated 3d mesh with skeletal animations. Basically for HI you will need a manager class that manages an ...

[quote user="Shawn Hargreaves"]I'm also a little confused by the format of the string you are passing. Do you really have a folder called "glow.exe" with a DLL file inside it? Try renaming that folder to not have a .exe extension. [/quote] Argh why didn't I see that... I formatted the dll name off ...

[quote user="Shawn Hargreaves"]The public key token is used for system assemblies that are installed into the GAC (Global Assembly Cache). Such assemblies are referenced by a strong name, which includes the assembly name, version, and key. For your own assemblies, you should normally just specify their filename, eg. ...

Background: I am creating a level editor and integrated the ContentBuilder class found in the WinForms #2 sample. Problem: I am unable to build content that requires my content pipeline dll. It seems to add my custom importers/processors I need to add a reference to the pipeline dll assembly. However, that doesn't seem to work off the ...

You neglected to tell spriteBatch.Begin to save & restore your renderstate.

You need to tell your GraphicsDevice to clamp rather than wrap texture coordinates.               device.SamplerStates[0].AddressU = TextureAddressMode.Clamp;  ...

[quote user="David Ang"]Hi I'm trying to attach the particle samples here, specifically the explosion. I want it to emit/fire from the tank's cannon. I'm not sure what to do, I tried this one: tankPosition + cannonBone.Transform.Translation to pass to the particle system starting position, but it seems its off. ...

[quote user="Mr Monaco"] Hi, I'm using Autodesk 3D Studio 2009 to create FBX files, which I then load as Models in my XNA 3D scene. I think the problem I'm having is caused by the fact that each model consists of groups of primitives (cylinders, boxes, etc) which are then rotated, translated and then grouped, all inside 3D ...

That GetData call will absolutely murder your framerate. It would be better to maintain a seperate 2D array for collision testing or perhaps use this technique to have the GPU handle the test.
