Hello, I am generally new to AI, I just wanted advice on weather I am implementing my AI correctly or if there is a more efficient way to implement what I wish to achieve. 
Here is my behaviour tree:
The states / Behaviours:
Wondering - Bot just wonders around random target locations I have place within the map
Chase - Bot chases after player when in sight range
ChaseFire - Bot fires as well as moves towards the player at the same time when in sight range and fire range
StationaryFire - Bot fires but does not move towards the player when in fire range
Here is my AIStateManager Service:
This basically checks if the player is within sight or/and firing range dependant on what it is it will set the state.
One thing I am currently stuck on is breaking out of the state Wondering, it will only break out once it reaches the target location and then proceed to chase. I would want it to break out as soon as the player was in range.
