in need of a bit of help with ogl textures

[ninogenio]

hey all,

ive been trying to get a simple texture loader/blitter class going but when i blit all i get is a white square and i cant for the life of me figuare out why?

i think its coming from the part where i push my image into vram but it looks like it should work.

if anyone can help out id be mighty chuffed cheers.

Yeah, you need to create the sprite AFTER you initialise OpenGL.  Right now you have it at the top of WinMain - move it to much later on.

cheers jim!

i cant believe i was being that daft 

i had to change it to GL_UNSIGNED_BYTE to get stop it crashing on my system but i thought GL_UNSIGNED_INT would work, not that it really makes much difference which one is used but i`m curious?

[Jim]

INT means that each component of the colour is an int - ie, each r,g,b,a is 4x32 bits!
