[Progress] Inventory system - part 2

Okay that worked a lot better than I expected! While messing with inventory system I realized that ItemPickup(global.items[0,0]); that I used to pick up the items, could be similarly replicated to remove simply by reversing the script it was calling. Now my obj_chest carries a different function compared to items that you pick up.

opened = false;

if(global.KEYS >= 1 && opened = false) {
     ItemRemove(global.items[0,0]);
     global.KEYS -= 1;
     image_index = 1;
     opened = true;
}

else {
     //show_debug_message("already opened");
}

Guess that means tomorrow I'll start working on the locked doors and finally start the dungeons! Surfaces and state machines are going to have to wait.
