A_Explode

From ZDoom Wiki

A_Explode [(int explosiondamage, int explosionradius [, bool hurtshooter])]

Performs an explosive (radius) attack. The amount of damage and the attack's radius are specified with explosiondamage and explosionradius. If the actor is a missile, you can set hurtshooter to 0 so that its originator will not be harmed by the attack. If the last parameter is omitted, the shot will assume normal behavior and damage the shooter -- one of the rare cases the engine will default to a value of 1.

Do not use the old actor property method of passing the parameters. Only use the parameters of A_Explode directly.
