Camera rotation z reset

Unity Engine
1

hi all,

i’m using a simple piece of code to tilt my camera on Z axis and want to be able to reset to 0 on keystoke at runtime
it work but work but not only on Z axis, i can’t figure how to restrain it to Z and leave X and Y be

i have tried transform.rotate instead but never achieve my goal

any ideas ?

code below

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

public class CameraTilt : MonoBehaviour
{

    public float tiltSpeed = 25f;
 
    void Update()
    {
        if (Input.GetKey(KeyCode.Delete))
            transform.Rotate(-Vector3.back * tiltSpeed * Time.deltaTime);

        if (Input.GetKey(KeyCode.End))
            transform.Rotate(Vector3.back * tiltSpeed * Time.deltaTime);

        if (Input.GetKey(KeyCode.Insert))
             Camera.main.transform.rotation = Quaternion.Euler(0, 0, 0);

    }
}

whel it does’nt event really work with quaternion euler, it reset my cam weirdly and compromise further move in the good direction…

Hello Jexmatex!

To achieve such a thing, you need to use the Euler angles (they’re the values you see in the Inspector). A Quaternion gives you a representation of the rotation, not the actual values.

Try something like this, it should do the trick :slight_smile:

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

public class CameraTilt : MonoBehaviour
{
    public float tiltSpeed = 25f;

    float currentRotX; //Value of the camera's current rotation.x value
    float currentRotY; //Value of the camera's current rotation.y value

    void Update()
    {
        currentRotX = this.transform.rotation.eulerAngles.x; //Stocking here the X value, which means you can move the camera while ingame, it'll still work
        currentRotY = this.transform.rotation.eulerAngles.y; //Stocking here the Y value

        if (Input.GetKey(KeyCode.Delete))
            transform.Rotate(-Vector3.back * tiltSpeed * Time.deltaTime);

        if (Input.GetKey(KeyCode.End))
            transform.Rotate(Vector3.back * tiltSpeed * Time.deltaTime);

        if (Input.GetKey(KeyCode.Insert))
             Camera.main.transform.rotation = Quaternion.Euler(currentRotX, currentRotY, 0); //We only reset the rotation on the Z axis
    }
}
