So your trying to code in Pein's Rinnegan? Is your game a rip of Davin Naruto's game? Because if it is you need to code in a var that works. I cant be too sure what it would be unless I know what the full code is.

no, no I dont make rips. I don't think i made a proc for the user by that name. I don't really know how one should look like because I haven't coded in a very long time.
Here is the code again:
obj/jutsu
layer=95
icon='jutsus.dmi'
MouseDrag()
mouse_drag_pointer=src
MouseDrop(obj/overobject,srclocation,overlocation)
if(istype(overobject,/obj/hotslot/))
screen_loc=overobject.screen_loc
usr.client.screen+=src
if(name==usr.slot1)usr.slot1=null
if(name==usr.slot2)usr.slot2=null

if(name==usr.slot7)usr.slot7=null
if(name==usr.slot8)usr.slot8=null
