GL.Color 顶点颜色

static function Color (c : Color) : void

Description描述

Sets current vertex color.

设置目前顶点颜色。

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

这个函数和OpenGL中的glColor4f(c.r,c.g,c.b,c.a)函数一样。其它的图形API也有对应的功能。

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.

为了使每个顶点的颜色对与不同的硬件,产生可靠的效果,你需要用着色器绑定在颜色通道里。

This function can only be called between GL.Begin and GL.End functions.

这个函数只能在GL.Begin 和GL.End 之间使用。

public class example : 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();
	}
}
// 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
//绘制一条红线,从右下角到左上角,在绘制一条黄线从屏幕的左下角到右上角

function OnPostRender() {
	if (!mat) {

	GL.Vertex3(1,1,0);
	GL.End();
	GL.PopMatrix();
