Scripting- Identifying a Hostile Enemy?

I have come up with a certain script for fun, but it would be infinitely better if I could pick out the hostile enemies for any given encounter when combat starts.

What I have right now is something like this:

Code

INIT Section
DB_ProtectedCharacters(CHARACTER_HOM_Astarte);
DB_ProtectedCharacters(CHARACTER_HOM_Astarte_SecondFight);
DB_ProtectedCharacters(CHARACTER_HIB_Leandra);


KB Section
IF
CharacterEnteredCombat(_Char, _ID)
AND
NOT _Char.isPlayer()
AND
NOT DB_ProtectedCharacters(_Char)
THEN
CharacterSetHitpointsPercentage(_Char, 0);

I imagine that I would use something like CharacterGetRelationToCharacter, but I'm not sure which value would be necessary.

You can use CharacterGetRelationToCharacter and check for a value less than 25 (so < 25).
Note that this will only work for Global characters. Local characters in your combat won't be handled by it.

There are some databases maintained by the main story scripts that could be helpful.
EvilDude - contains all 'Evil' characters. These are defined at game initialization by those with a relation to Arhu of < 25. It can be added to at anytime.
IsStoryNPC - is a database containing what I think are protected characters (uses call CharacterMakeStoryNpc)
The query CharacterGetAttitudeTowardsPlayer might also be useful, not sure its difference to CharacterGetRelationToCharacter but they are different
