这是我无意间逛国外论坛发现的，感觉还可以就分享给大家。原文 http://pastebin.com/dJabCfWn
如下图所示，用法和UGUI自带的outline和shadow一样，可以同时使用。
代码在这里了。我加了个判断，它原来的有越界的隐患。
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
[AddComponentMenu("UI/Effects/Gradient")]
public class Gradient : BaseVertexEffect {
[SerializeField]
private Color32 topColor = Color.white;
[SerializeField]
private Color32 bottomColor = Color.black;
public override 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;
}
}
}
}我也在测试中，欢迎大家提意见。
如果你的项目升级到了5.2 请使用下面的代码，感谢代码的提供者。@獨立遊戲開發熊
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
[AddComponentMenu("UI/Effects/Gradient")]
public class Gradient : BaseMeshEffect
{
[SerializeField]
private Color32
topColor = Color.white;
[SerializeField]
private Color32
bottomColor = Color.black;
public override void ModifyMesh (Mesh mesh)
{
if (!IsActive ()) {
return;
}
Vector3[] vertexList = mesh.vertices;
int count = mesh.vertexCount;
if (count > 0) {
float bottomY = vertexList [0].y;
float topY = vertexList [0].y;
for (int i = 1; i < count; i++) {
float y = vertexList [i].y;
if (y > topY) {
topY = y;
} else if (y < bottomY) {
bottomY = y;
}
}
List<Color32> colors = new List<Color32> ();
float uiElementHeight = topY - bottomY;
for (int i = 0; i < count; i++) {
colors.Add (Color32.Lerp (bottomColor, topColor, (vertexList [i].y - bottomY) / uiElementHeight));
}
mesh.SetColors (colors);
}
}
}

BaseMeshEffect是怎么来的？
5.3.6可以 5.4的还没试using UnityEngine;using System.Collections;using System.Collections.Generic;using UnityEngine.UI;[AddComponentMenu(“UI/Effects/Gradient”)]public class Gradient : BaseMeshEffect{ public Color32 topColor = Color.white; public Color32 bottomColor = Color.black; public override void ModifyMesh(VertexHelper vh) { if (!IsActive()) { return; } var count = vh.currentVertCount; if (count == 0) return; var vertexs = new List(); for (var i = 0; i < count; i ) { var vertex = new UIVertex(); vh.PopulateUIVertex(ref vertex, i); vertexs.Add(vertex); } var topY = vertexs[0].position.y; var bottomY = vertexs[0].position.y; for (var i = 1; i < count; i ) { var y = vertexs
.position.y; if (y > topY) { topY = y; } else if (y < bottomY) { bottomY = y; } } var height = topY – bottomY; for (var i = 0; i < count; i ) { var vertex = vertexs 
; var color = Color32.Lerp(bottomColor, topColor, (vertex.position.y – bottomY) / height); vertex.color = color; vh.SetUIVertex(vertex, i); } }}

error CS0534: `Gradient’ does not implement inherited abstract member `UnityEngine.UI.BaseMeshEffect.ModifyMesh(UnityEngine.UI.VertexHelper)’问一下我是5.3 为啥会出这个报错
我也出现这个问题了
我的是5.3.4的
检查一下参数类型，ModifyMesh 里面是VertexHelper 不是Mesh
因为BaseMeshEffect里面声明了ModifyMesh(VertexHelper)抽象类，继承BaseMeshEffect的Gradient类要实现那个抽象类
请问博主，ugui 下 bbcode 要怎么搞？
我们是自己写的。。
松哥，求UGUI插件下载地址
不用下载unity4.6以后都自带。。

喔。。雨松大大，再请教一个问题吗，你有没有遇到过使用艺术字的时候，mask遮罩不起作用的情况？
