CheckWayPoints(object)

Checks to see if an NPC has a valid waypoint to walk to.

int CheckWayPoints(
    object oWalker = OBJECT_SELF
);

Parameters

oWalker

The creature to check for valid waypoints. (Default: OBJECT_SELF)

Description

This function takes oWalker's tag, and looks for waypoint tags with matching names: "POST_<tag>" and "WP_<tag>_01" (always checked). If the NW_FLAG_DAY_NIGHT_POSTING spawn-in condition has been set in oWalker's OnSpawn script, then "NIGHT_<tag>" and "WN_<tag>" are also sought.

If ANY of these new tags is the tag of a valid waypoint, the function returns true.

Remarks

CheckWayPoints() could be useful as a sanity check on NPCs with waypoints.

This is used by SetListeningPatterns() in nw_i0_generic to do prevent NPCs with waypoints to walk from going to sleep at night (unimplemented).

Requirements

#include "x0_i0_walkway"

Version

1.22

Example

// Source for CheckWayPoints():
int CheckWayPoints(object oWalker = OBJECT_SELF)
{
    object oWay1;
    object oWay2;
    object oWay3;
    object oWay4;
    string sTag = GetTag(oWalker);
    if(GetSpawnInCondition(NW_FLAG_DAY_NIGHT_POSTING))
    {
        oWay2 = GetWaypointByTag("NIGHT_" + sTag);
        oWay4 = GetWaypointByTag("WN_" + sTag + "_01");
    }
 
    oWay1 = GetWaypointByTag("POST_" + sTag);
    oWay3 = GetWaypointByTag("WP_" + sTag + "_01");
 
    if(GetIsObjectValid(oWay2) || GetIsObjectValid(oWay4) || GetIsObjectValid(oWay1) || GetIsObjectValid(oWay3))
    {
        return TRUE;
    }
    return FALSE;
}
