How to make a jetpack using ACS or ZScript?

[Nailz the Ravager]

Hi there. I need some help. How to make a jetpack that can be turned on and off using the Space [/ i] button and which will use the player's ammunition?

Here you, go, something more fancy. A jetpack that behaves the same as the jetpack in duke nukem 3d. Made in zscript. Activated and deactivated from inventory item. Uses the inventory item as an ammo. Could be easily modified to use any kind of ammo.

Code: Select all

class JetPack : CustomInventory
{
	int jetpackSwitch;

	Default
	{
		
		-Solid
		+inventory.invbar
		+inventory.AlwaysPickup
				
		Tag "Jetpack";
		inventory.icon "I_NEDV";
		inventory.amount 100;
		inventory.maxamount 100;
		inventory.interhubamount 100;
	}
	
	States
	{
		Spawn:
			JETP A -1; //supply your own sprite
			Stop;

		Use: 
			TNT1 A 0
			{
				if(invoker.jetpackSwitch == 0) {return ResolveState("Activate");}
				if(invoker.jetpackSwitch == 1) {return ResolveState("Deactivate");}
				return ResolveState(null);
			}
			Stop;
		Activate:
			TNT1 A 0
			{
				invoker.jetpackSwitch = 1;
				A_Giveinventory("jetpackActive", 1);
			}
			Stop;
		Deactivate:
			TNT1 A 0
			{
				invoker.jetpackSwitch = 0;
				A_TakeInventory("PowerJetpack", 1);
				A_TakeInventory("jetpackActive", 1);
			}
			Stop;
	}

}
