Tank urret rotation - Need help.

Question

Hi guys,

for 3 three hours I try to rotate a tank turret now... And I only get it to smoothly look to the target. But the problem is how can I fix the Z axis of the turret after looking/slerping to the target?

Here is an example:

After this phase of rotation I want that the local rotation of the turret gets to the same level as the tank hull again. Can anyone help me please? I tried so many experiments on my own with this stupid tank :D

Here is my latest code experiment:

 // The Important snippet from the Weapon.cs Script
 //
 // Transform weaponHolder = <turret set via inspector>
 // The parent of the turret is the hull.
 
 Vector3 direction = target.transform.position - transform.position;
 Quaternion toRotation = Quaternion.LookRotation(direction);
 Quaternion newRotation = Quaternion.Slerp(weaponHolder.transform.rotation, toRotation, Time.deltaTime * 1.5);
 weaponHolder.rotation = newRotation;
 weaponHolder.localEulerAngles = new Vector3(weaponHolder.localEulerAngles.x,
                                     weaponHolder.localEulerAngles.y,
                                     weaponHolder.parent.localEulerAngles.z);

Take a look at my answer here:

You will need to open up the comments at the bottom of my answer and scroll down. The code is just below the link to a package that demonstrates the script.

Hi... Can you pls help me pls modify my code here it is

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class TurretRotater : MonoBehaviour { // e.g. 0.2 = slow, 0.8 = fast, 2 = very fast, Infinity = instant [Tooltip("If rotationSpeed == 0.5, then it takes 2 seconds to spin 180 degrees")] [SerializeField] [Range(0, 10)] float rotationSpeed = 0.5f;

 [Tooltip("If isInstant == true, then rotationalSpeed == Infinity")]
 [SerializeField] bool isInstant = false;

 Camera _camera = null;  // cached because Camera.main is slow, so we only call it once.

 void Start()
 {
     _camera = Camera.main;
 }

 void Update()
 {
     Ray ray = _camera.ScreenPointToRay(Input.mousePosition);
     Quaternion targetRotation = Quaternion.LookRotation(ray.direction);

     if (isInstant)
     {
         transform.rotation = targetRotation;
     }     
     else
     {
         Quaternion currentRotation = transform.rotation;
         float angularDifference = Quaternion.Angle(currentRotation, targetRotation);
         // will always be positive (or zero)
         if (angularDifference > 0) transform.rotation = Quaternion.Slerp(
                                      currentRotation,
                                      targetRotation,
                                      (rotationSpeed * 180 * Time.deltaTime) / angularDifference
                                 );
         else transform.rotation = targetRotation;
     }
 }

}
