Quaternion.slerp only on the y axis

[MadJohny]

Hey I’ve been making an AI script today, ran into alot of problems if you look at the qeustions I made only today… anyway this is another part of the script:

 using UnityEngine;
    using System.Collections;

public class EnemyScript : MonoBehaviour {

	public int health = 100;
	public int rotationSpeed = 1;
	public int moveSpeed = 1;
	
	public GameObject[] gos;
	public GameObject closestPlayer = null;
	public float distance;
	
	void Start(){
		InvokeRepeating("FindClosestPlayer", 0.5f,0.5f);
	}
	
	void FixedUpdate(){
		if(closestPlayer != null){
			transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(closestPlayer.transform.position - transform.position), rotationSpeed * Time.deltaTime);
			transform.position += transform.forward * moveSpeed * Time.deltaTime;
		}
	}

ok the script does what I want, it looks at the player and wals forward at a certain speed, but it looks at the player in all axis, like if I jump he rotates on the x axis, and I don’t want that to happen, I only want the Quaternion.Slerp work on the y axis, this is what I’ve tried to do:

using UnityEngine;
using System.Collections;

public class EnemyScript : MonoBehaviour {

	public int health = 100;
	public int rotationSpeed = 1;
	public int moveSpeed = 1;
	
	public GameObject[] gos;
	public GameObject closestPlayer = null;
	public float distance;
	
	void Start(){
		InvokeRepeating("FindClosestPlayer", 0.5f,0.5f);
	}
	
	void FixedUpdate(){
		if(closestPlayer != null){
			transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(closestPlayer.transform.position - transform.position), rotationSpeed * Time.deltaTime);
			transform.position += transform.forward * moveSpeed * Time.deltaTime;
		}
		transform.rotation = Quaternion.Euler(new Vector3(0f,transform.rotation.y,0f));
	}

I don’t know why but this way it doesn’t rotate at all, like it goes straight forward, and doesn’t rotate to look at the player, help would be apreciated.

Thanks in advance.

Hi,
transform.rotation is a quaternion itself. using its y component doesn’t give you what you expect.

try using
transform.rotation = Quaternion.Euler(new Vector3(0f,transform.eulerAngles.y,0f));

Unity - Scripting API: Transform.eulerAngles
