File Name And Class Name Dont Match
You Have Probably had this error before but im new and when i Try To Add This Script To My Model But It Says File Name And Class Name Dont Match Ive Tryed Renaming The File To AI,ai,Ai But It Still Doesnt Work, Here Is The Script p.s Its Not My Script /*

Hi, maybe it has to do with .meta files not renamed if you renamed your files in the OS and not in Unity.
Try those steps to restart "clean" : backup first, cleanup your script folder of all ai.js and ai.meta (.meta files may be hidden, make them visible in the OS or Unity's project settings/editor settings). Remove remaining AI component from all your objects. Save. Then recreate an ai.cs file and go back to Unity and check that it compiles. Then assign it to your gameobject.
