Nothing. The rest of the problems where with the .meta flies i reinstalled the version 2019.4.21f1 and nothing i want to launch my game by summer please help

This may someday work as an approach, but I would not recommend it because you won’t actually have learned anything. The problem with computers is that they require you to engineer them, not just copy/paste code at them.

Engineering is an iterative building process, whereby you make one tiny thing, test it, then move forward. The instant something doesn’t work, you immediately stop and you do not keep typing and adding more stuff. You go back and fix what was broken, otherwise you’re just building on top of more junk.

I recommend you back up and go to the beginner Unity tutorials because we know they work. This stuff is NOT hard to get right, but it does require you to get it 100% right. Every piece of code must be spelled, capitalized, punctuated and in many cases have whitespace only and always in certain places. Even one piece out of place makes it all fail.

When you have a specific problem, here is how to report your problem productively in the Unity3D forums:
