Scripted Waypoints

[Rob]

In NWN1, you could create an NPC walk path by placing a series of waypoints named WP_<creature tag>_##. Now in NWN2, you can attach a script to that walk path, which fires every time an NPC hits a waypoint. Using the function GetCurrentWaypoint(), you can script events for each specific way point.

For example, I created an NPC named customer. I created an office building with a receptionist, two waiting rooms, and four offices. I placed these waypoints:

WP_customer_01 - at the entrance
WP_customer_02 - at the receptionist
WP_customer_03 - at the first waiting room
WP_customer_04 - at the second waiting room
WP_customer_05 - at the first office
WP_customer_06 - at the second office
WP_customer_07 - at the third office
WP_customer_08 - at the fourth office
WP_customer_09 - at the exit

Using the following script named wp_customer, I can simulate customers entering the office building, interacting with random clerks, and then exiting.

Code: Select all

//	WAYPOINT SCRIPT
//
//	NOTES:
//	StandardRedirectorNode:		THIS FUNCTION TELLS THE NPC TO HIDE FOR A CERTAIN AMOUNT OF TIME
//								BEFORE CHANGING CLOTHES AND WALKING WAYPOINTS AGAIN.
//	StandardRoadNetworkNode:	THIS FUNCTION SENDS THE NPC TO A WAYPOINT PICKED RANDOMLY FROM A LIST.
//								IF THE ONLY WAYPOINT AVAILABLE IS THE CURRENT WAYPOINT,
//								THE NPC IS SENT TO THE REDIRECTOR NODE SPECIFIED.
