I have another problem; in my example, the 8-direction behavior is disabled, but when I click with my mouse to move the character with the pathfinding behavior, then the 8-direction behavior reactivates, which is not normal.
It reactivates because you're enabling it in "On Pathfinding Arrived" event.
It pisses me off, why don't they ever reply?
You have mistakes in your code, it's not their fault or their obligation to help you fix them.
