held_this_item

int held_this_item(int held,
                   object holder,
                   mixed arg)


This method is called by the inheritable when the object is change from being held to unheld, or vica versa. This should be used to turn on and off light sources and so on. The method will also be called with a 2 if the object was held and we are doing an initialisation sequence.

• Parameters:
  held - 1 if the item is held, 0 if not, 2 if held on init
  holder - this is person already holding it when removed, new holder when held
  arg - an argument use in the autoloading, passed into init_dynamic_arg
• Returns:
  1 if the hold/remove was successful

hold_item

varargs int * hold_item(object who,
                        int pos)


Attempts to free up enough limbs for this_object to be held. If items are dropped to make this possible, who is notified. If enough limbs are freed, attempts to hold this_object. If the position is undefined (ie: not specified) then it will try and choose a limb by itself.

The return numbers are the limb numbers that were used by holding the item.

hold_item: As designed by Tannah!
