How do i use this script??

[Statyk]

AddUseItemCallback(string& asName, string& asItem, string& asEntity, string& asFunction, bool abAutoDestroy);

Ok...I want to know how i use this...
asName - internal name
asItem - internal name of the item
asEntity - entity to be able to use the item on
asFunction - function to call
abAutoDestroy - determines whether the item is destroyed when used

asName - Name of the function itself
asItem - Name of the item that is being used (i.e., a key)
asEntity - entity to be able to use the item on (i.e., the door)
asFunction - function to call when you use the item on the entity
abAutoDestroy - determines whether the item is destroyed when used/removed from your inventory


Example (this is a basic "unlock the door with key" script):

void OnStart()
{
AddUseItemCallback("", "key01", "door", "keydoor_func", true);
}

void keydoor_func(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("door", false, true);
}
