| It's a good idea if you're using OpenGL to read the OpenGL red and blue books which are free online, then you'll have a good understanding of how to do whatever you want. You have to first load your sprite image into a pixmap. Then you have to set up OpenGL environment and upload the pixmap as a texture. Then you have to switch on texture mapping and draw a quad with texture coords. |

| FWIW, I prefer the OpenGL SuperBible to the Red/Blue book. Get an older version for cheap. |

| Take a look at my opengl blobby objects tutorial thing, it has some sourcecode which includes the basic parts you need to upload a texture and draw it as a quad on the screen. Search the tutorials forum for `blob` and see the opengl blob tutorial. But yes besides that you should read the opengl red and blue books. Everyone was a blitzmax newbie at the start, I knew nothing about OpenGL. Reading most of the red book online gave me a pretty good understanding of most things about it, enough to write some code. It is somewhat more complicated than a single line of code, but it is doable. |
