I'm making a costume single player map in hammer, and i was wondering if there is a way to have the player re-spawn on death like in coop maps.

thanks in advance.

ChickenMobile made this script which makes you respawn like the coop bots do. It's intended for making you appear to be P-Body (changing the player model, and spawning robot effects on "death"), but it shouldn't be difficult to remove those components.
You can't actually make the player respawn after dying (they'll always reload from the last save), so instead this script just detects when the player is about to die and teleports them to a reassembly machine.

thanks for this, i think i may just leave it as a robot, it will look better that way
