When AI Perception Sight is Lost Node?

I am using OnPerceptionUpdated(AI Perception) to sight an actor.

When the sight is broken how do I signal something of this?

i.e. I want to use a branch to (if sight = true) set blackboard boolean as true
if branch (if sight = false) set blackboard boolean as false

to stop ai behavior tree branch from running.

OnPerceptionUpdated(AI Perception), for each loop, get actors perception(AI Perception), break info, get(0) last sensed stimuli, break ai stimulus, successfully sensed. true = entered sight, false = left sight.

OR

OnTargetPerceptionUpdated(AI Perception), break stimulus, successfully sensed. true = entered sight, false = left sight.

The AI gets stuck in Behavior Tree if I manage to run around him to his backside.

Is this fixable? He will not continue in the AI Tree…

I am setting my blackboard boolean as true/false with the OnTargetPerceptionUpdated(AI Perception) stimulus successfully sensed true/false in that order.

I’m not sure because I can’t see your BT but.

If you manage to run around him to his backside because his rotation speed is slower than you going to his backside then, I would suggest increasing his rotation speed or try adding Hearing on AIPerception so that when you get to his back side he will look at the location of the noise.

It’s probably your blackboard decorator, try putting its observer aborts to both
