Apparently it doesn’t work when I add Physics together with it. Any ways to solve this?
These two behaviors are not really compatible as they both try to set the position of the object on their own. 
So… what should i do? I need the pathfidning and the physics.
What do you want to achieve using both ?
A survival top view shooter.
So, you don’t need the physic behavior at all. 
I need it for projectile motion and push objects.
Put invisible object on top of the movable ones and use them for pathfinding.
You can use the builtin forces and collision checking instead of the Physic engine.
