problems with game object rotation?

Questions & Answers

I have a sphere and I have a problem finishing spinning it with drag. How do I save and assign that new rotation value to zero without the sphere returning to the initial rotation? since I want that new position to be assigned values ​​of zero to start the rotation again from where the sphere stayed when lifting the finger with that new position but with initial values ​​of zero to rotate correctly since with my code when lifting the finger or start a new drag starts with the values ​​from scratch and removing the part of OnMouseUp uses the previous values ​​where the finger is lifted and begins to rotate erroneously.

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

public class RotateSphere : MonoBehaviour
{
	float rotationSpeed = 5f;


	void OnMouseDrag()
	{
		float XaxisRotation = Input.GetAxis("Mouse X") * rotationSpeed;
		float YaxisRotation = Input.GetAxis("Mouse Y") * rotationSpeed;
		// select the axis by which you want to rotate the GameObject
		transform.Rotate(Vector3.down, XaxisRotation);
		transform.Rotate(Vector3.right, YaxisRotation);
	}

	void OnMouseUp()
	{
		this.transform.localRotation = Quaternion.Euler(0f, 0f, 0f);
	}
}

Hi @Alucard-Belmont, I don’t quite understand what you want to do, but here is how you can save a rotation of an object to apply later (or to another object), and how to reset all axes rotations to zero.

  1. to save a rotation, create a new Quaternion and set it equal to some object’s transform.rotation for example

     Quaternion savedRotation = gameObject1.transform.rotation;

you can do the reverse and set any object rotation to that, say if you want to copy one object’s rotation to another.

  1. to reset (zero out) a rotation, just set the object’s rotation equal to Quaternion.Identity

Easy peasy!

@streeetwalker I managed to get it. All he needed was to spin it like a globe. After several things that I had to do, I finally had time to continue with my project and when looking for solutions I made it work. The code is the following:

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

public class RotationSphere : MonoBehaviour
{
	public float rotationSpeed = 3f;


	void OnMouseDrag()
	{
		float XaxisRotation = Input.GetAxis("Mouse X") * rotationSpeed;
		float YaxisRotation = Input.GetAxis("Mouse Y") * rotationSpeed;

		transform.Rotate(Vector3.up, - XaxisRotation * rotationSpeed, Space.World);
		transform.Rotate(Vector3.right, YaxisRotation * rotationSpeed, Space.World);
	}
}
