/* * NOTE FROM SOMEBODY WHO DID SOME HOUSEKEEPING AROUND THIS ASS-CODE * There's absolutely no documentation on most of this so I'd like to write this down to help you get a grasp of how this works and how redundant it all is. * Let's assume you live in a horrible horrible universe where nobody coded inventory datums yet. Damn. Now let's say you want your new mob to be able to wear a jumpsuit. * * First thing the mob needs is a variable for the inventory slot, like var/obj/item/w_uniform = null. Start by the most awful part and modify /obj/item/proc/mob_can_equip() * to account for your mob. It has a switch for every slot, and jumpsuits go in under slot_w_uniform, so probably just copypaste how monkeys do it. * * Good, now the item thinks the mob can equip it. Now the mob has to be ACTUALLY be able to equip it. Go and modify or create mob/your_mob/equip_to_slot(). Again, it's a switch of * all slots. You'll see that that proc also handles the icon refreshing, so you have to create mob/your_mob/update_inv_w_uniform() as well. Good luck there because iconcode is also ass. * * You can't do anything with the jumpsuit yet though, you need to add it to mob/your_mob/get_item_by_slot() for most things to work. * Small detail: Your mob cannot unequip their jumpsuit yet. You need to add it to mob/your_mob/u_equip() * Oh yeah, you need to add the new variable for the jumpsuit to mob/your_mob/get_all_slots(). I know, I know, this is why we need inventory datums. * * Okay, so your mob still has no HUD element for their inventory slot. That takes a /obj/abstract/screen/inventory... beats me how most of it works, but you do need to have it point to * slot_id = slot_w_uniform and define a new screen_loc for it. I would advise you to just look at code/_onclick/hud/monkey.dm and do the ol' monkey see, monkey do. * When you click on that obj/abstract/screen/inventory, it calls attack_ui() which by default will just call equip_to_slot_if_possible(item, slot_id) * At this point I think you need to handle some UI shitcode in mob/your_mob/update_inv_w_uniform(), something like w_uniform.screen_loc = the_screen_loc_you_defined_earlier * * For other players to be able to strip and forcibly put on the uniform on your mob, you need to give it a fancy mob/your_mob/show_inv(), and put HREF links that you'll pick up * in mob/your_mob/Topic() that finally point to handle_strip_slot(). If you search for (href_list["item"]) I'm sure you'll be able to figure this out. * * Good luck. * * So, a list of all methods used: * /obj/item/proc/mob_can_equip() -> mob/equip_to_slot() -> update_inv_[slot]() * get_item_by_slot(), u_equip(), get_all_slots() * obj/abstract/screen/inventory -> ??? -> attack_ui()? -> equip_to_slot_if_possible() -> ??????? -> update_inv_[slot]()? * show_inv() -> Topic() -> handle_strip_slot() */ //These procs handle putting stuff in your hand.
