Keeping Inventory Items After Using Them

[Mad Dal 85]

I noticed that the "Ritual Knife" from R667 stays in the inventory even after you use it. How is that done?

I wish to use that method for other items in my mod such as the Summon Sphere but that keeps disappearing after use. So i just want to know how to keep them in the inventory when you use it? (ie, unlimited use of it)

 

Thanks

You need to mark the item using as failed. Depends which type of actor the item is:

 

If it is a DECORATE CustomInventory actor, then finish the Use state with fail instead of stop.

If it is a ZScript Inventory actor, then return false from the Use virtual method.

i don't understand zscript to be honest. i tried looking for tutorial videos about zscripting on doom and found nothing.

Yeah, thats because you dont learn zscript from watching videos. You can learn zscript by using it. But not by watching videos.

sorted it. thanks again.

 

one last question: is there any way to put a cooldown effect on it so it can not be used again for a period of time?

I think you can make a dummy Powerup class that serves as a "timer", give it to the player when they use the item, and check if the "timer powerup" is in inventory when player tries to use the item.
