标题: Unity文字渐变Gradient 5.4更改
从5.22开始就遇到这个问题，
现在又遇到了，研究修改了1个多小时终于解决不报错了，分享给大家

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
using System;

[AddComponentMenu("UI/Effects/Gradient")]
public class Gradient : BaseMeshEffect
{
[SerializeField]
private Color32 topColor = Color.white;
[SerializeField]
private Color32 bottomColor = Color.black;

public override void ModifyMesh(VertexHelper vh)
{
      if (!this.IsActive())
         return;

      List<UIVertex> vertexList = new List<UIVertex>();
      vh.GetUIVertexStream(vertexList);

      ModifyVertices(vertexList);

      vh.Clear();
      vh.AddUIVertexTriangleStream(vertexList);
}

public void ModifyVertices(List<UIVertex> vertexList)
{
      if (!IsActive())
      {
         return;
      }

      int count = vertexList.Count;
      if (count > 0)
      {
         float bottomY = vertexList[0].position.y;
         float topY = vertexList[0].position.y;

         for (int i = 1; i < count; i++)
         {
            float y = vertexList[i].position.y;
            if (y > topY)
            {
                  topY = y;
            }
            else if (y < bottomY)
            {
                  bottomY = y;
            }
         }

         float uiElementHeight = topY - bottomY;

         for (int i = 0; i < count; i++)
         {
            UIVertex uiVertex = vertexList[i];
            uiVertex.color = Color32.Lerp(bottomColor, topColor, (uiVertex.position.y - bottomY) / uiElementHeight);
            vertexList[i] = uiVertex;
         }
      }
}
}
