Inventory How to / Car shop? in ARMA 2 & OA : MISSIONS - Editing & Scripting Posted April 27, 2013 Inventory: Store the units items in an array and build a fancy GUI that displays it :). Nothing magic. Shop: Store the objects and prices availiable in an array that displays in a fancy GUI when the shop is opened. Add a "buy" button to the GUI that calls a function to reduce the players money by the items price and spawns/adds the object to the player. Pretty straight forward though if you just want the basics. But you should start with small steps as a beginner and not something like city life 2 in mind. You should write small independant functions/missions/scripts first to get used to sqf.
