  • llDeleteCharacter - Convert the current linkset back to a standard object
  • llEvade - Causes the character to keep away from the object or avatar identified by the key.
  • llExecPathingCmd - Send a command to the pathing system - currently only supports stopping pathing.
  • llGetClosestNavPoint - Accepts a point in region-local space and returns either an empty list or a list containing a single vector which is the closest point on the navmesh to the point provided.
  • llFleeFrom - Attempt to get at least 'distance' away from 'source' - provided in region-local coordinates.
  • llNavigateTo - Navigate to a destination provided in region coordinates. The destination may be in another region.
  • llPatrolPoints - Patrol a provided set of points provided as vectors.
  • llPursue - Causes the character to chase after the object or avatar identified by the key.
  • llUpdateCharacter - Update character properties.
  • llWanderWithin - Wander within an area approximately 'scale' in radius centered at 'origin'. Wandering means choosing a random point in the area and navigating to it. After arrival, a new random point will be chosen and navigated to.
