pitch rotation

Hi again.

im fighting with rotations in objects local space and anything i try dont want to work. for a while i thought i understand the logic but it seems i was wrong.

here is a sample code:

using UnityEngine;
using System.Collections;

public class ShipMouseLook : MonoBehaviour {

	public enum RotationAxes { MouseXAndY = 0 }
	public RotationAxes axes = RotationAxes.MouseXAndY;
	public float sensitivityX = 15F;
	public float sensitivityY = 15F;

	float rotationX = 0F;
	float rotationY = 0F;

	void Update ()
	{
		if (axes == RotationAxes.MouseXAndY && !Input.GetKey (KeyCode.LeftControl)){			

			/*
			rotationX += Input.GetAxis ("Mouse X") * sensitivityX;
			rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
			transform.localEulerAngles = new Vector3 (-rotationY, rotationX, 0);
			*/

			/*
			rotationX = transform.localEulerAngles.y + Input.GetAxis ("Mouse X") * sensitivityX;
			rotationY = transform.localEulerAngles.x + Input.GetAxis ("Mouse Y") * sensitivityY;
			transform.localEulerAngles = new Vector3 (rotationY, rotationX, 0);
			*/

			/*
			transform.RotateAround(transform.position, transform.TransformDirection(transform.up),
			Input.GetAxis ("Mouse X") * sensitivityX * Time.deltaTime);
			transform.RotateAround(transform.position, transform.TransformDirection(transform.right),
			Input.GetAxis ("Mouse Y") * sensitivityY * Time.deltaTime);
			*/

			/*
			transform.Rotate(transform.up, Input.GetAxis ("Mouse X") 
			 * sensitivityX * Time.deltaTime, Space.Self);
			transform.Rotate(transform.right, Input.GetAxis ("Mouse Y") 
			 * sensitivityY * Time.deltaTime, Space.Self);
			*/

			/*
			rotationX += Input.GetAxis ("Mouse X") * sensitivityX;
			rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
			transform.localRotation = Quaternion.Euler(rotationY, rotationX, 0);
			*/

			/*
			rotationX += Input.GetAxis ("Mouse X") * sensitivityX;
			rotationY += Input.GetAxis ("Mouse Y") * sensitivityY;
			transform.localRotation = Quaternion.identity 
			 * Quaternion.Euler(0, rotationX, 0) 
			 * Quaternion.Euler(rotationY, 0, 0);
			*/
		} 

		if(Input.GetKeyUp (KeyCode.LeftControl)) {
			Screen.lockCursor = true;
			Screen.showCursor = false;
		} else if (Input.GetKeyDown (KeyCode.LeftControl)) {
			Screen.lockCursor = false;
			Screen.showCursor = true;
		}
	}
	
	void Start ()
	{

	}
}

there are a couple of “tries” as you can see and none of them works.

problem with “rotate” and “rotatearound” is that the object has SOME rotation around Z axis too, I cant understand why

every try with eulerangles failed as when the object look stright up, it rotates the object around world Y instead of local Y

I start to give it up… help pls

Take a look at this thread. Pretty straightforward.

Edit:

After the back and forth, I understand what the problem is. If you rotate around 2 axis that move together, you can actually achieve any rotation on any 3 axis (try it with your hand, you’ll understand quickly).

What you’ll want to do is rotate in 2 steps and relative to different spaces:

transform.Rotate(
	0f,
	Input.GetAxis ("Mouse X") * sensitivityX * Time.deltaTime,
	0f, 
	Space.World);
transform.Rotate(
	Input.GetAxis ("Mouse Y") * sensitivityY * Time.deltaTime,
	0f,
	0f, 
	Space.Self);

Notice one rotation is relative to Space.World and the other to Space.Self

Edit2:

Controlling the spaceship on all 3 axis feels much more natural and let’s you rotate all axis based on Space.Self. Here’s the code:

(and what it looks like here, camera movements and all)

using UnityEngine;
using System.Collections;

public class Rotater : MonoBehaviour {
	
	public enum RotationAxes { MouseXAndY = 0 }
	public RotationAxes axes = RotationAxes.MouseXAndY;
	public float sensitivityRoll = 45F;
	public float sensitivityPitch = 30F;
	public float sensitivityYaw = 35f;
	
	float rotationX = 0F;
	float rotationY = 0F;
	
	void Update ()
	{
		if (axes == RotationAxes.MouseXAndY && !Input.GetKey (KeyCode.LeftControl)){

		    transform.Rotate(
				Input.GetAxis ("Mouse Y") * sensitivityPitch * Time.deltaTime,
				Input.GetAxis ("Mouse X") * sensitivityYaw * Time.deltaTime,
				Input.GetAxis ("Mouse X") * -sensitivityRoll * Time.deltaTime,
				
				Space.Self);

		}
		
		if(Input.GetKeyUp (KeyCode.LeftControl)) {
			Screen.lockCursor = true;
			Screen.showCursor = false;
		} else if (Input.GetKeyDown (KeyCode.LeftControl)) {
			Screen.lockCursor = false;
			Screen.showCursor = true;
		}
	}

}

Hope I understood you correctly, but the problem is exactly that you are trying to rotate around two local axis. Because it changes everytime you rotate, sooner or later the global Z axis will change too. Just try and replace the localEulerAngles with this:

transform.rotation = Quaternion.Eulers(rotationY,rotationX,0);

Hope this is what you wanted
