NWScript:

//:://////////////////////////////////////////////////////////////////

//:: Sound an alarm

//:: SC_SOUNDALARM

//:://////////////////////////////////////////////////////////////////

/*

Place this script in the "OnPerception" and "OnHeartbeat" events.

If the NPC perceives (sees) a PC, it will try to run towards a predefined waypoint (lAlarm), shout a warning and activate and encounter.

When the PC is perceived, the NPC sets the local variable "iSoundAlarm". The NPC will then say a string (string sShout), run towards a waypoint (lAlarm). When it gets within a certain range of the waypoint (fSoundDistance), it will shout another warning (sAlarm) and activate an encounter (oEncounter).

To use, add this script to the "onUserDefined" script. You also need a waypoint for where the alarm is to be sounded and an encounter. Change the tags or the code as you see fit. Make sure the "OnPerceived" and "OnHeartbeat" events are flagged on in the NPCs spawn script.

Possible uses for this script : Let a sentry alert other troops. The PCs have a chance to stop the NPC before it sounds the alarm, and thus avoids the encounter.

Please send any comments you might have :-)
