JavaScript => public var colors: Color[];
C# => public Color[] colors;

Description 描述

Vertex colors of the mesh.

网格的顶点颜色。

If no vertex colors are available an empty array will be returned.

如果无顶点颜色可用，返回空数组。

JavaScript:

	// Sets the vertex color to be red at the y=0 and green at y=1.
	// (Note that most builtin shaders don't display vertex colors, you can
	// use eg. a particle shader to see vertex colors)
 
	function Start () {
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;
		var vertices : Vector3[] = mesh.vertices;
		var colors : Color[] = new Color[vertices.Length];
 
		for (var i = 0; i < vertices.Length;i++)
			colors[i] = Color.Lerp(Color.red, Color.green, vertices[i].y);
 
		mesh.colors = colors;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;
        Color[] colors = new Color[vertices.Length];
        int i = 0;
        while (i < vertices.Length) {
            colors[i] = Color.Lerp(Color.red, Color.green, vertices[i].y);
            i++;
        }
        mesh.colors = colors;
    }
}

For performance reasons, consider using colors32 instead. This will avoid byte-to-float conversions in colors, as well as use less temporary memory.

出于性能因素，考虑使用colors32替代，这将避免字节到浮点数转换颜色，以及使用更少的临时内存。
