In my game I am working on unreal engine 4, I can consume resources that I have in my inventory. For example, I can consume fire elements in the inventory and shoot fire arrows. When I do this, my resource counters in the inventory should be updated to reflect the resource consumption. I am going to cover this part today, so that not only the counter will be updated, but also, I wouldn't be able to set fire to arrows if I don't have available fire elements in the inventory.
