Sets current texture coordinate (x,y) for all texture units.
In OpenGL this matches glMultiTexCoord for all texture units or glTexCoord
when no multi-texturing is available. On other graphics APIs the same
functionality is emulated.
This function can only be called between GL.Begin and GL.End functions.
// Draws a Quad in the middle of the screen and
// Adds the material's Texture to it.
var mat : Material;
function OnPostRender() {
if (!mat) {
Debug.LogError("Please Assign a material on the inspector");
return;
}
GL.PushMatrix();
mat.SetPass(1);
GL.LoadOrtho();
GL.Begin(GL.QUADS);
GL.TexCoord2(0,0);
GL.Vertex3(0.25,0.25,0);
GL.TexCoord2(0,1);
GL.Vertex3(0.25,0.75,0);
GL.TexCoord2(1,1);
GL.Vertex3(0.75,0.75,0);
GL.TexCoord2(1,0);
GL.Vertex3(0.75,0.25,0);
GL.End();
GL.PopMatrix();
}
