UGUI之Text彩虹字

脚本Rainbow直接挂在Text下

使得每个字母或者汉字均为一种随机颜色

Rainbow脚本如下：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.Collections.Generic;[AddComponentMenu("UI/Effects/Gradient")]
public class Rainbow : BaseMeshEffect
{private Color32[] colors;public override void ModifyMesh(VertexHelper vh){if (!IsActive() || vh.currentVertCount == 0){return;}List<UIVertex> vertices = new List<UIVertex>();vh.GetUIVertexStream(vertices);int count = vertices.Count;colors = new Color32[count / 6];for (int i = 0; i < colors.Length; i++){//随机颜色float r = Random.value;float g = Random.value;float b = Random.value;colors[i] = new Color(r, g, b);}UIVertex v = new UIVertex();for (int i = 0; i < vh.currentVertCount; i++){vh.PopulateUIVertex(ref v, i);v.color = colors[i / 4];vh.SetUIVertex(v, i);}}
}
