• Casters and Statics or LOS

Having trouble with npc casters casting through Mountains and fences, If someone could give me the specific directories to edit or code to tweak it'd be appreciated I've looked and it stumped me.

First I would suggest you to look in your npcdesc.cfg found in distro/config for your npc description. Then you'll find a script attached to your NPC that you may probably find in distro/scripts/ai. The just open the file and add a check when it calls the function for casting.

Something like:

Code: Select all

If( CheckLineOfSight( npc, victim ))
      CallYourFunctionHere();
endif

Okay so none of my Ai Scripts call for this code and I would definately like to try it out, where would I insert in a script such as this?

Ai For Undead Spellcasters

Code: Select all

you need to check more than just the src. You need to check the include files too. Since a LOS check would logically be in the main loop and/or a fighting loop, you might want to check the include files that seem to be named appropriately...

include "../pkg/npcs/main_ai/main/mainloop_killpcs_normal";
include "../pkg/npcs/main_ai/combat/fightmode_normal";
