# CUSTOM NPC BEHAVIOR — teach a villager to flee when hurt.
#
# An npc_behavior is a Verse class that rides ON TOP of an NPC's built-in brain.
# You attach it to an NPC Character Definition; OnBegin runs the moment the
# character is simulating. Unlike a creative_device, an npc_behavior gets a
# handle to its OWN character through GetAgent[] / GetFortCharacter[], then drives
# it with the navigatable and focus interfaces.
#
# This villager stands still until something damages them — then it sprints away
# from the attacker and keeps its eyes locked on the threat the whole time.
fleeing_villager := class(npc_behavior):

    # How far to run when spooked (centimeters).
    FleeDistance : float = 1200.0

    # OnBegin runs when the NPC enters the simulation. Wire up its damaged event.

        if:
            Agent := GetAgent[]
