Doing some coding. I know that A_JumpIfInTargetInventory changes depending on whether the target has a specific item in their inventory, i.e. a player having a backpack or a BFG. Is there any way to check the player's inventory at the start of a level? What I want to try to do is make a mod that replaces existing enemies with slightly different ones, i.e. a ZombieMan with a ShotgunGuy. I want the enemies to get stronger and strong in later levels. Any idea how, or IF I can code that?
