I thought it was entity within?
Edit ill see if there is anything else i can use
Edit I could use entity within Zone and put it at the other side from the player
Edit I edited the script to look like this do you think it will work it is designed to be placed in a trigger zone at the zombie side of the window
desc = destroy barrier if entity stands at it for 4 seconds
;triggers
