Destroyable barrier that regenerates after you buy it again

i want a barrier that sentries can destroy, but it comes back if you buy it again

Destroyed props are gone for the remainder of the game, so you’ll need to put down multiple props.

you would have to place many over each other for the amount of barriers that can be destroyed. To do that you would need to make all but one invisable and have it despawn after being destroyed. then have the rest in order spawn after the one above is destroyed.
