public static function MultiTexCoord2(unit: int, x: float, y: float): void;
public static void MultiTexCoord2(int unit, float x, float y);
public static def MultiTexCoord2(unit as int, x as float, y as float) as void

Description

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(); }
