 * FUNCTION PROTOTYPES

 **********************************************************************/



// Determine whether the specified X0_COMBAT_FLAG_* is set on the target

int GetCombatCondition(int nCond, object oTarget=OBJECT_SELF);



// Set one of the X0_COMBAT_FLAG_* values on the target

void SetCombatCondition(int nCond, int bValid=TRUE, object oTarget=OBJECT_SELF);



// This function checks for the special tactics flags and

// chooses tactics appropriately for each.

// Currently available:

// X0_COMBAT_FLAG_{RANGED,DEFENSIVE,COWARDLY,AMBUSHER}

//

// Note that only one special tactics flag should be applied

// to a single creature for the most part!

//

// Returns TRUE on success, FALSE on failure.

int SpecialTactics(object oTarget);



// Special tactics for ranged fighters.

// The caller will attempt to stay in ranged distance and

// will make use of active ranged combat feats (Rapid Shot

// and Called Shot).

// If the target is too close and is not currently attacking

// the caller, the caller will instead try to find a ranged

// enemy to attack. If that fails, the caller will try to run

// away from the target to a ranged distance.

// This will fall through and return FALSE after three

// consecutive attempts to get away from an opponent within

// melee distance, at which point the caller will use normal

// tactics until they are again at a ranged distance from

// their target.

// Returns TRUE on success, FALSE on failure.

int SpecialTacticsRanged(object oTarget);



// Special tactics for ambushers.

// Ambushers will first attempt to get out of sight

// of their target if currently visible to that target.

// If not visible to the target, they will use any invisibility/

// hide powers they have.

// Once hidden, they will then attempt to attack the target using

// standard AI.

// Returns TRUE on success, FALSE on failure.

int SpecialTacticsAmbusher(object oTarget);



// Special tactics for cowardly creatures

// Cowards act as follows:

// - if you and your friends outnumber the enemy by 6:1 or

//   by more than 10, fall through to normal combat.

// - if you are currently being attacked by a melee attacker,

//   fight defensively (see SpecialTacticsDefensive).

// - if there is a "NW_SAFE" waypoint in your area that is

//   out of sight of the target, run to it.

// - otherwise, run away randomly from the target.

// Returns TRUE on success, FALSE on failure.

int SpecialTacticsCowardly(object oTarget);



// Special tactics for defensive fighters

// This will attempt to use the active defensive feats such as

// Knockdown and Expertise, and also use Parry mode, when these

// are appropriate. Falls through to standard combat on failure.

// Returns TRUE on success, FALSE on failure.

int SpecialTacticsDefensive(object oTarget);

For those in the first post: Just add a (integer) variable to the NPCS in the advanced tab.
 
The Combat behaviour flags work similar, except that they can be supposedly combined with other stuff, hence the crazy hex-notation of the values.
Basically, you set up an int variable named X0_COMBAT_CONDITION and then set it to

1 for the behaviour of X0_COMBAT_FLAG_RANGED
2 for the behaviour of X0_COMBAT_FLAG_DEFENSIVE
4 for the behaviour of X0_COMBAT_FLAG_COWARDLY
8 for the behaviour of X0_COMBAT_FLAG_AMBUSHER

How about other type of flags?

I'm trying to make some slave NPCs run away and dissapear once the PC finishes a short one line conversation with them...
I found that there is a useful flag for this kind of situation: NW_FLAG_ESCAPE_LEAVE, which is activated with ActivateFleeToExit.
From NWN Lexicon:
"ActivateFleeToExit will cause an NPC to flee to a waypoint called EXIT_ +

How would i set the flag on the NPC? through an OnSpawn script with SetSpawnInCondition?

Ok, I realized I can easily create such a script by using NW_C2_DEFAULT9 and just uncommenting a line in there.

I tried it and it works perfectly!

If anyone else ever wants to have an NPC run off and disappear, here is how:

The new script which has this flag activated is "flagleave_onspawn" and goes into the OnSpawn of the NPC
The script that activates the action is "npc_leave" (can be placed in Action Taken of a conversation line for instance)
All you need then is a waypoint named EXIT_ +
