Sets current texture coordinate (x,y) for the actual texture unit.
In OpenGL this matches glMultiTexCoord for the given texture unit
if 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.
// Changes between two textures assigned to a material
// When pressed space
var mat : Material;
private var flagTex : boolean = true;
function Update() {
if (Input.GetKeyDown(KeyCode.Space)) {
if(flagTex) {
flagTex = false;
} else {
flagTex = true;
}
}
}
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);
if (flagTex) {
GL.MultiTexCoord2(0,0,0); // main texture
} else {
GL.MultiTexCoord2(1,0,0); // second texture
}
GL.Vertex3(0.25,0.25,0);
if (flagTex) {
GL.MultiTexCoord2(0,0,1);
} else {
GL.MultiTexCoord2(1,0,1);
}
GL.Vertex3(0.25,0.75,0);
if (flagTex) {
GL.MultiTexCoord2(0,1,1);
} else {
GL.MultiTexCoord2(1,1,1);
}
GL.Vertex3(0.75,0.75,0);
if (flagTex) {
GL.MultiTexCoord2(0,1,0);
} else {
GL.MultiTexCoord2(1,1,0);
}
GL.Vertex3(0.75,0.25,0);
GL.End();
GL.PopMatrix();
}
