Original Post
To clear up any confusion: I'm using DirectX 9 - The December 2005 SDK release. Non-managed. Fixed-function pipelining. Microsoft Visual Studio 2003 C++. The problem that (I think) I am having is within the class I have written to handle all my map models and units that I'm using for a top-down 3-d strategy game. The probem I am experiencing is that when I run my program, the screen renders and I am able to see the LPDIRECT3DTEXT9 text that I have set up to draw during the renderloop, and the screen updates itself normally and shows the FPS count and everything, but the actual game-world is not rendered. The problem may be in the class itself, or in some memory management problems with me and pointers and the new operator (which I'm not quite used to doing in C++, I'm a java guy, really - but you can't do good 3-d in Java so.....). I'll post code of my class and renderloop as well as other misc. code. Any and all help is appreciated (not in the form of flames, they're only half-appreciated if they're half-helpful). Declarations (note that the Direct3d objects and device objects ARE initalized later on, but not shown here): Here's the class' source - it's probably the problem: Here's the initialization of GameObject class' objects: Here is my renderloop (I cut off the boring ending part where the text is drawn and the scene is ended and presented): Edit: I even added source code complete with a compiled EXE for people to download and see that it doesn't work. But WHY!? http://rapidshare.de/files/22410308/NSRM.rar.html [Edited by - DragonGeo2 on June 7, 2006 6:52:09 PM]
