Package vehicleRespawn or whatever the function is, and just return before the parent::stuff. Look into packages and parenting, im pretty sure theres a sticky for it.
I know how to use packages and parenting, but I don't want to overwrite the function.
EDIT: I don't need to know how to respawn vehicles anymore. I was planning to create a zombie defense gamemode with waves. Zombies should not respawn after they die; instead, they will spawn with the next wave.
But now I've decided to use hole bots instead of the not-very-intellgient bots of Event_Bots. So I don't need help anymore.
