POL System Events

Description:

This document describes all the "System Events" (Sysevents) that the POL core uses. These are enabled in Control Scripts using the EnableEvents() function. Only these events listed here should be used in the EnableEvents() function. You may not define User Events with any of these values (or any of the reserved values in sysEvent.inc). To use a user event in your script, you must not use EnableEvents(), just send it using SendEvent() (or process_obj.sendevent()) and look for it normally in the receiving script. Some of the Sysevents below are ranged, meaning you may specify a world distance in EnableEvents() beyond which the script will not receive the event. Use DisableEvents() to disable any of the Sysevents.

SYSEVENT_ITEM_GIVEN
Explanation
Item dropped on an NPC generates this event. Also sets the following cprops on the item: "GivenBy": PC's serial, "GivenTo":NPC's serial, "GivenTime":gameclock value when item was given.
Important: The item is moved to a storage area until the script handling the event moves it to a real container. If the item is not before by the time the event object goes out of scope (including passed to a subroutine! use 'byref' to prevent the event from being destroyed before it can be passed to the handling subroutine), the item will automatically be moved back to its old container, and the aformentioned cprops are erased.

SYSEVENT_GONE_CRIMINAL
Explanation
The GONE_CRIMINAL event lets the system tell the NPC when a mobile has become a criminal (from a previously non-criminal state) by firing this event and placing a character reference to the new criminal in the source field of the event. If used in conjunction with the ENTERED_AREA system event, then guards should be able to do their guarding work without needing to do polling scans of the area around them periodically. On ENTERED_AREA events, you check to see if the person entering the area is a criminal or not. On GONE_CRIMINAL events, you know that the person who was already in the area has become a criminal from previously being innocent.
