update: the weapon crafting brick and the weapon selling brick are complete
here's how it works:
for weapon selling, you store weapons into this info brick and other players are able to come up to it and buy stuff from it
the price of weapons is decided entirely by you at the moment
for weapon crafting:
the weapon crafting brick is this big-ass brick that you buy. it'll be cheap. you're able to upgrade it by feeding it corpses which makes it demonically more efficient (its not decided what these upgrades will do but they will do stuff). when you upgrade it with corpses, it becomes illegal and police are able to bust it with their batons. to craft a weapon, you just approach the brick and if you have enough material for a weapon the brick will let you craft it. its really simple and doesn't complicate things
all i have to do now is get the model for it and weapon crafting/selling will be complete
