Declaration

public static void Color(Color c);

Description

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;

public class Example : MonoBehaviour { // Draws a red line from the bottom right // to the top left of the Screen // And a yellow line from the bottom left // to the top right of the Screen 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(); } }
