Hey Gang, Just winding how I can turn smoothly my GameObject 90 degrees so my battleship Will give my enemies a good broadside.
the enemy finds and flies at a target and once in rang, i want the ship to turn so the side of my battleship is facing the enemy. :slight_smile:

You already seem to have code for looking at the target so use same code, but offset rotation on Y-axis by 90 degrees. I didn’t test this, but I think it should more or less do what you want.

_direction = (Target.transform.position - transform.position).normalized;
_lookRotation = Quaternion.LookRotation(_direction);
_lookRotation = Quaternion.Euler(new Vector3(_lookRotation.eulerAngles.x, _lookRotation.eulerAngles.y + 90f, _lookRotation.eulerAngles.z));
transform.rotation = Quaternion.Slerp(transform.rotation, _lookRotation, Time.deltaTime * RotationSpeed);

You have your look rotation, multiply it by Euler 0, 90, 0 and you achieve left broadside look direction and -90 will make it right broadside, simplest and best working solution.

Hello,
Call this function you would battleship Turn to enemy
public var enemy : Transform;
function SOMETHING (){
transform.LookAt (enemy);
}
