storing simple rotation and position properties

Unity Engine
1

hey, as someone who just started coding, i’m still struggeling with some basic methods in unity.

i’ve been experimenting with some simple movements and rotations.

what i couldn’t figure out is how i can store a single rotation angle or also the angles of all three axis in variable
in order to rotate the object (cube for example) back to it.

for example:

a cube rotates around the x axis and moves foward in deltatime…
whenever i press the “y” key the current rotation status should be stored
whenever i press the “x” key the current position should be stored
whenever i press the “c” key the cube should simply move and rotate back to the stored statuses
whenever i press the “v” key the cube’ position should immediately go back to the stored statuses, e.c jump back to it…

it may sound simple for you but i simply can’t get it done… :slight_smile:

This should be relatively straightforward:

using UnityEngine;

public class RotatingCubeExample : MonoBehaviour {

    public float lerpSpeed = 5f;

    private Vector3 _storedPosition;
    private Quaternion _storedRotation;

    // Need to lerp for key 'C'!
    private float _lerpTime = 1f;
    private Vector3 _lerpFromPosition;
    private Quaternion _lerpFromRotation;

    private void Update() {
        if (_lerpTime < 1f) {
            _lerpTime = Mathf.Min(1f, _lerpTime + lerpSpeed * Time.deltaTime);
            transform.localPosition = Vector3.Lerp(_lerpFromPosition, _storedPosition, _lerpTime);
            transform.localRotation = Quaternion.Lerp(_lerpFromRotation, _storedRotation, _lerpTime);
        }

        if (Input.GetKeyDown(KeyCode.Y)) {
            // Store current rotation.
            _storedRotation = transform.localRotation;
        }
        else if (Input.GetKeyDown(KeyCode.X)) {
            // Store current position.
            _storedPosition = transform.localPosition;
        }
        else if (Input.GetKeyDown(KeyCode.C)) {
            // Gradually tween back to stored position.
            _lerpTime = 0f;
            _lerpFromPosition = transform.localPosition;
            _lerpFromRotation = transform.localRotation;
        }
        else if (Input.GetKeyDown(KeyCode.V)) {
            // Immediately restore position and rotation.
            transform.localRotation = _storedRotation;
            transform.localPosition = _storedPosition;
        }
    }

}

Disclaimer: The above script has not been tested, but hopefully you will see the basic idea :slight_smile:
