GL.TexCoord2

설명

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.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Material mat;
    void 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(0.25F, 0.25F, 0);
        GL.TexCoord2(0, 1);
        GL.Vertex3(0.25F, 0.75F, 0);
        GL.TexCoord2(1, 1);
        GL.Vertex3(0.75F, 0.75F, 0);
        GL.TexCoord2(1, 0);
        GL.Vertex3(0.75F, 0.25F, 0);
        GL.End();
        GL.PopMatrix();
    }
}
