Image not drawing
Author
For some reason...my image isn't drawing. I know the image exists because I can write the values to the log(sizes return the right size, the texture handle returns the number 2), and the program isn't crashing when I try to draw the image. Its hard because the loading code is spread all over the place, but I doubt its the loading code.
theres certain things u cant do between glBegin()..End()
one of them is binding a texture like youre doing there
