Don't affect the object if it's already intersecting

Hello everybody. Sorry if this is a simple question but I have been caught up on it for a while.

I have a pawn that is the player, it can walk around and do some stuff. How ever the player can press a button to spawn a bomb at it’s location. I want this bomb to collide for everyone so no one can walk through it unless you was inside of the bomb when it was spawned, then I need you to be able to still walk out fine without getting stuck or being pushed away by the collision. Is that possible?

I have an idea to manually check if any players are in the bounding box when spawned, doing a test and using that to determine if they should or should collide but this feels very awkward and i’m hoping there is some easy solution to get this behaviour.

If you need an example of what I mean take a look at bomber man, when a player places a bomb they can still move around on that tile until they leave the tile, then the bomb prevent them from walking through. Any player who was not on the tile when the bomb was placed will not be able to walk though it even if the other player is still no collided in the bomb.

Thank you!
