How to make a script that make some vip people(bought GamePass) cant get damage?

I'll just save you the trouble and just tell you this, you don't request scripts on here. We're here to help you fix your scripts or help you get a general idea of what you can do to improve your scripts, etc.

But you could start off by using the UserOwnsGamePassAsync API and simple if statements to give the player who owns the gamepass infinite health, etc.

You mean infinite health if user own a gamepass?

Try the script yourself first
