操作方法
在Unity中新建一个工程，并且在场景中添加一个 Plane，具体如下图
导入一个序列图，一般的序列图效果如下图
在在工程中新建一个Shader 脚本，命名为UVAnimation，双击打开进行代码编辑，具体如下图
UVAnimation 脚本具体代码如下图
UVAnimation 脚本具体内容如下： Shader "Custom/UVAnimation" { Properties { _Color("Base Color", Color) = (1,1,1,1) _MainTex("Base(RGB)", 2D) = "white" {} } SubShader { tags{"Queue" = "Transparent" "RenderType" = "Transparent" "IgnoreProjector" = "True"} Blend SrcAlpha OneMinusSrcAlpha Pass { CGPROGRAM #pragma vertex vert #pragma fragment frag #include "UnityCG.cginc" float4 _Color; sampler2D _MainTex; struct v2f { float4 pos:POSITION; float2 uv:TEXCOORD0; }; float2 moveUV(float2 vertUV) { //因为序列图有12帧所以是12 float textureNum = 12.0; float timePerFrame = 100; float index = frac(_Time.x / textureNum * timePerFrame); float2 uvScale = float2(1 / textureNum, 1); if (index <= uvScale.x) return vertUV * uvScale; else if (index <= 2 * uvScale.x) return vertUV * uvScale + float2(uvScale.x, 0.0); else if (index <= 3 * uvScale.x) return vertUV * uvScale + float2(2 * uvScale.x, 0.0); else if (index <= 4 * uvScale.x) return vertUV * uvScale + float2(3 * uvScale.x, 0.0); else if (index <= 5 * uvScale.x) return vertUV * uvScale + float2(4 * uvScale.x, 0.0); else if (index <= 6 * uvScale.x) return vertUV * uvScale + float2(5 * uvScale.x, 0.0); else if (index <= 7 * uvScale.x) return vertUV * uvScale + float2(6 * uvScale.x, 0.0); else if (index <= 8 * uvScale.x) return vertUV * uvScale + float2(7 * uvScale.x, 0.0); else if (index <= 9 * uvScale.x) return vertUV * uvScale + float2(8 * uvScale.x, 0.0); else if (index <= 10 * uvScale.x) return vertUV * uvScale + float2(9 * uvScale.x, 0.0); else if (index <= 11 * uvScale.x) return vertUV * uvScale + float2(10 * uvScale.x, 0.0); else return vertUV * uvScale + float2(11 * uvScale.x, 0.0); } v2f vert(appdata_base v) { v2f o; o.pos = mul(UNITY_MATRIX_MVP, v.vertex); o.uv = moveUV(v.texcoord.xy); return o; } half4 frag(v2f i):COLOR { half4 c = tex2D(_MainTex, i.uv) * _Color; return c; } ENDCG } } }
脚本编译正确，回到Unity新建一个材质，把Shader设置为新建的 Shader，图片附上对应的序列帧图片，并把材质赋给 Plane，具体如下图
运行场景，就实现序列帧动画效果，具体如下图
