Script Name: Open Coffin / Spawn Vampire
Description: A PC opens a coffin and out pops a vampire. This will only happen once so PC's don't continuously spawn vampires as they open/damage the coffin.
Instructions on Use: Put script in the OnDamaged and OnOpen events of a coffin.  Also, make sure to use the blueprint res/ref of the creature you wish to spawn.

NOTE:  Some people are successful by using the creature TAG and not blueprint res/ref.

Script 1 (OnDamaged & OnOpen):
