KAI_Wander()

KAI_Wander ([Int Attempts = 24, Double RunRad = 256, Int MaxSteps = 72, Double DetourFactor = 0.5, Double AngleLimit = 10, Int ChaseFlags = 0, Int Flags = 0])

Parameters:

• Attempts: How many positions to try per next position picked. Default is 24.
• RunRad: The radius around which to find a viable position to go to. Default is 256 map units.
• MaxSteps: How many steps the actor is allowed to take before having to find a new position to move to. Default is 72.
• DetourFactor, AngleLimit, ChaseFlags, Flags: These parameters work the same as in KAI_MoveTowards(). However the DetourFactor is halved.

Return type(s):

• None

Function:

Makes the NPC pick random positions around RunRad for them to head to, wandering aimlessly looking for a fight. Basically a more sophisticated and organic acting A_Wander.

Actors reach the position they are supposed to go to once they are within MeleeRange of it, similar to ZDoom patrol points.

Like A_Wander() it also handles making friendly monsters follow players instead of wandering, unless +DONTFOLLOWPLAYERS is on.

Example

This stupid Pinky just pointlessly wanders around.
