UGUI之文字颜色渐变和描边
发表于2019-01-15
在做开发的时候,遇到这样一个需求:对文字渐变色做设置,同时还要加上描边的效果。为此,这里就给大家分享一个好用的代码,可以直接拿来使用,用作任何的设置。(描边效果是Unity自带的,添加Outline组件进行设置就好了)
注意:一定是字体渐变色脚本在,描边组件的上边,向下图这样会报错的。
代码如下:
using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityEngine.UI; using System; /// <summary> /// 渐变字体 /// </summary> [AddComponentMenu("UI/Effects/Gradient")] public class FontGradient : BaseMeshEffect { public Color32 topColor = Color.white; public Color32 bottomColor = Color.black; public bool useGraphicAlpha = true; public override void ModifyMesh(VertexHelper vh) { if (!IsActive()) { return; } var count = vh.currentVertCount; if (count == 0) return; var vertexs = new List<UIVertex>(); 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[i].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[i]; var color = Color32.Lerp(bottomColor, topColor, (vertex.position.y - bottomY) / height); vertex.color = color; vh.SetUIVertex(vertex, i); } } }
