URP Fog of War => https://github.com/Tunied/CE-FOW-URP
- BuildIn 已经不在维护. 就旧项目一直在用. 这种方案比较麻烦的地方是所有Shader都要重写.
- 另外 如果能升级到 URP 建议直接用URP Build-In is already history

fist CopyEngine Fog of War (CEFow) is not extend MonoBehaviour. so you need call
CEFowFacade.instance.InitAsNew($propery);
when the game start.
the $propery you pass in is defined in CEFowProperty.cs file. check for more detail in that file.
as the CEFow is not extend MonoBehaviour, so you need call
CEFowFacade.instance.Update();
the frequency of this function called is up to you, you can call it once pre frame or once pre second.
even you can call it only when some explorer changed.
it will not hit any performance issue for call it once pre frame. CEFow will only repaint the Fow texture when something really changed.
there are two type of explorer , static and not static. check more detail with the demo project.
CEFow provide a function
CEFowFacade.IsWorldPosInView($worldPosition)
let you check is the point in fog or not.
check more detail in DebugStalker.cs file
if you curiousness on how i made this,please check more info on my Blog
