HELP - How to make NPCs Drop Loot if the Player Has a Certain Item in Inventory?

[Plarux]

Hello,

 

Today I'm trying to figure out how to make an NPC drop item(s), but only if the player has a certain item in their inventory.

For example, the player kills a radroach. If the player doesn't have a knife in their inventory, the player won't receive any Radroach Meat.

Also, would I have to use a script for instances where the player could have a knife or combat knife?

 

Thank you,
