GL.Color

Descripción

Sets current vertex color.

In OpenGL this matches glColor4f(c.r,c.g,c.b,c.a); on other graphics APIs the same functionality is emulated.

In order for per-vertex colors to work reliably across different hardware, you have to use a shader that binds in the color channel. See BindChannels documentation.

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(0);
        GL.LoadOrtho();
        GL.Begin(GL.LINES);
        GL.Color(Color.red);
        GL.Vertex3(1, 0, 0);
        GL.Vertex3(0, 1, 0);
        GL.Color(Color.yellow);
        GL.Vertex3(0, 0, 0);
        GL.Vertex3(1, 1, 0);
        GL.End();
        GL.PopMatrix();
    }
}
