Yeah um so this isn’t possible unless you have a barrier everywhere.
You’d have to have a barrier at each possible spot the player could be and activate that specific one, which would take an insane amount of memory.
If this is a tag map, you can use my invincibility guide instead, and I haven’t checked this guide out yet but you might want to read this.
Nevermind I have, but it’s not really invincibility, read the comments.
