I made a map and i dont want powerup s in it, definitely not nuke and deathmachine. How can i remove it. tried to remove the #using lines that i think is related to powerups but it didn't work

Put this at the bottom of your main() function.

zm_powerups::powerup_remove_from_regular_drops( "minigun" );

And I believe for the Nuke you'd just replace "minigun" with "nuke".
