[HELP!!!!] ProjectorMultiPlyMask Shader add Unlit

I want to add Unlit shader.

PLEASE HELP ME !!!

 Shader "Projector/MultiplyMask" {
     Properties {
         _ShadowTex ("Cookie", 2D) = "gray" {}
         _FalloffTex ("FallOff", 2D) = "white" {}
         _AlphaTex("Mask Clamp", 2D) = "" {}
         _ProjectorDir("ProjectorDir", Vector) = (0,0,0,0)
     }
     Subshader {
         Tags {"Queue"="Transparent"}
         Pass {
             ZWrite Off
             //ZTest Equal
             Cull Back
             ColorMask RGB
             Blend DstColor Zero
             Offset -1, -1
