Ok, forgive this really stupid problem, but its driving me crazy. I have extensive 2d and 3d programming experience in C and C++ using both Open GL and Direct X, but I wanted to mess arou d with DBPro for quickly prototyping games.

At the moment though i'm going nuts because I can't seem to mix 2D and 3D graphics in the same viewport. I know I must be doing something wrong, but I don't yet know DBPro well enough. Here is my code:



What I Want to do is display a terrain generated form a heightmap, with a 2d hud overlayed ontop of it. What IS happening is the terrain is completely covering the display and the 2d image is not shown.

The problem is, you have automatic screen updating on. DB is handling screen refreshing for you. Your 3D object is an entity you've created, so as DB refreshes the screen, it keeps refreshing the entity, but the image is only pasted once and isn't considered an entity.

To solve the problem, set yourself up a program loop and manually handle the screen refeshing yourself.



Hope that helps.

Insiiiiiiiiiiiiiiiiiiiiiiiide!

Thank you. I See what you mean now, and it stemmed from not understanding how DBPro works. My understanding was it handled ALL that for me. Guess I should have realize that some of the traditional methods would still be present

Thanks again!

In this particular scenario, it can do everything for you. Instead of pasting the image to the display, make a sprite instead :

SPRITE 1, 0, 0, 1
