Ok, I have a cloud texture mapped over my players head. I am trying to get the texture to move over the surface of the quad, without affecting the other textures of course. I cannot get it to work. Here's an idea of what I'm trying.
static float trantex = 0.0f;
glTranslatef(0.0f, 0.0f, trantex);

glBindTexture(GL_TEXTURE_2D, textures[2]);
	glTexCoord2i(0, 0);
	glVertex3f(-128, 32, -128);
	glTexCoord2i(1, 0);
	glVertex3f(128, 32, -128);
	glTexCoord2i(1, 1);
	glVertex3f(128, 32, 128);
	glTexCoord2i(0, 1);
	glVertex3f(-128, 32, 128);

trantex += 0.01;

anyone know how to do this? [edited by - xg0blin on December 27, 2002 3:02:10 AM]
