[1.16.1] Fixing Squid Entity's movement

[DavidQF555]

I am making a custom entity that extends a SquidEntity, but I cannot get it to move to where I want. Squids normally only move randomly so their travel method looks like: 

 public void travel(Vector3d p_213352_1_) {
      this.move(MoverType.SELF, this.getMotion());
   }

and the random movement looks like: 

 this.squid.setMovementVector(f1, f2, f3);

I'm trying to use the tryMoveToXYZ method from the navigator. Changing the travel method to: 

@Override
public void travel(Vector3d vec) {
 	setMovementVector(vec.subtract(getPositionVec()).normalize());
  super.travel(vec);
}

makes the squid go in weird directions and it just doesn't stop until it hits a wall. I replaced the PathNavigator with a SwimmerPathNavigator. How could I make the travel method actually work for navigating to where I want it to?
