Unity 2DTIleMap物体出现线条问题 最近做2D项目的时候，相机移动，2D物体之间会有线条，特别是那种TileMap制作的。 解决方法： Main Camera 关闭 MSAA  链接: 最根本的解决方法上Shader，此篇博客更详细
```csharp
Shader "Sprites/Pixel Snap/Alpha Blended"
{
Properties
{
_MainTex ("Sprite Texture", 2D) = "white" {}
_Color ("Main Color", Color) = (1,1,1,1)
}
SubShader
{
Tags
{
"Queue"="Transparent"
"IgnoreProjector"="True"
"RenderType"="Transparent"
}
Cull Off
Lighting Off
ZWrite Off
ZTest Always
Fog { Mode Off }
Blend SrcAlpha OneMinusSrcAlpha
Pass
{
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#pragma fragmentoption ARB_precision_hint_fastest
#include "UnityCG.cginc"
sampler2D _MainTex;
float4 _MainTex_ST;
fixed4 _Color;
struct appdata_t
{
float4 vertex : POSITION;
float2 texcoord : TEXCOORD0;
};
struct v2f
{
float4 vertex : POSITION;
float2 texcoord : TEXCOORD0;
};
v2f vert(appdata_t IN)
{
v2f OUT;
OUT.vertex = mul(UNITY_MATRIX_MVP, IN.vertex);
OUT.texcoord = TRANSFORM_TEX(IN.texcoord, _MainTex);
// Snapping params
float hpcX = _ScreenParams.x * 0.5;
float hpcY = _ScreenParams.y * 0.5;
#ifdef UNITY_HALF_TEXEL_OFFSET
float hpcOX = -0.5;
float hpcOY = 0.5;
#else
float hpcOX = 0;
float hpcOY = 0;
#endif
// Snap
float pos = floor((OUT.vertex.x / OUT.vertex.w) * hpcX + 0.5f) + hpcOX;
OUT.vertex.x = pos / hpcX * OUT.vertex.w;
pos = floor((OUT.vertex.y / OUT.vertex.w) * hpcY + 0.5f) + hpcOY;
OUT.vertex.y = pos / hpcY * OUT.vertex.w;
return OUT;
}
fixed4 frag(v2f IN) : COLOR
{
return tex2D( _MainTex, IN.texcoord) * _Color;
}
ENDCG
}
}
