> * id(itemId\[, itemIds...]):
> * > itemId \[Required]: Item id to register the event to.
>   >
>   > itemIds \[Optional]: All extra item ids to register.
> * aid(actionId\[, actionIds]): Follows the same behavior as the `id(itemId[, itemIds...])` method.
> * uid(uniqueId\[, uniqueIds]): Follows the same behavior as the `id(itemId[, itemIds...])` method.
> * allowFarUse(bool):
