GetHandleItem

Thunder_Eye	I cant seem to find the GetHandleItem/SetHandleItem function, anyone knows where I can find it?

02-25-2006, 09:10 PM	#2
shadow1500	JASS: function GetHandleItem takes handle subject, string name returns item return GetStoredInteger(LocalVars(), I2S(H2I(subject)), name) return null endfunction

Thunder_Eye	Ok so how is the "Set" one? same as the integer?

02-25-2006, 09:14 PM	#4
Vexorian	There is no SetHandleItem Only SetHandleHandle

Thunder_Eye	Oh ok thank you, another fast question then. How do I move an item from say slot 1 to slot 6 on a unit?

02-25-2006, 09:21 PM	#6
Vexorian	JASS: native UnitDropItemSlot takes unit whichUnit, item whichItem, integer slot returns boolean

Thunder_Eye	to bad, Im no good with natives :/ anyway I found a solution by dropping the item, creating a item called "empty" in slot 1-5 if they are empty, then giving the item to the hero and atlast removing the "empty" items. Finally my backpacksystem is done!! I will post it in resources later when Im almost done with the RPG. Thank you for your help

Vexorian	That solution is terrible and your backpack system will be awful unless you use the darn native BTW what's stopping you from using a native? It seems you are good enough to use functions, natives are only different in the fact that they are implemented natively in the game but the way to use them is the same as when calling functions

Well Ive never understood the "takes blabla returns blabla" part.

A function like that can sometimes look like

function AbcFoF takes unit u returns nothing
call KillUnit(u)
endfunction

And Ive never understood where its sets the u variable.
Logicaly it would be that when you call the function you use
call AbcFoF(GetTriggeringUnit())
or something but Ive never seen anyone do it like that.

And with the return part it is the same
function AspGH takes nothing returns integer (dont know if this is right might be that it should be "returns h")
return h
endfunction

bump*
so the call could look like

JASS:

call UnitDropItemSlot(GetTriggeringUnit(),UnitItemInSlotBJ(GetTriggerUnit(), 1),6)

I'm just wondering what the boolean is for and how do I use it?

EDIT:
this gives me an error
call UnitDropItemSlot(u,GetLastCreatedItem(),6)

Anitarf	The line looks fine, it shouldn't give you an error when compiling. However, there is a different mistake there, in JASS, item slots go from 0 to 5. Also, regarding the first example of calling the native, it's GetTriggerUnit(), not GetTriggeringUnit().

Yeah I just wrote it as I thought it was, didnt check if it where correct.
Oh yeah, forgot the slot thing, that is probably it. will test it

EDIT: So what were the boolean for? didnt get an answer
EDIT2:
call UnitDropItemSlot(u,GetLastCreatedItem(),5)
still gives me an error, can it be because I havent included the boolean anywhere?
EDIT3:Problem Solved, I forgot I was using a global (udg_)

Though still on the boolean question

Anitarf	The boolean it returns probably means if the operation was successful or not. It could fail if the unit didn't have the item, or if you specified an invalid slot number. Many functions return such a boolean, like the issue order natives, for example. You don't have to use it; it's just there at your disposal if you need it for some reason.
