Changing the Axis of a Copied Rotation

Hello coding masters. I’m new to coding and have run into what I’m sure is an extraordinarily simple problem- however it’s so specific that I haven’t been able to solve it with a simple google search.

I’ve got two simple elements here in this scene: a capsule-like shape in 3D space, and a blue icon representing that capsule in 2D space.



That 2d icon is like a joystick controlled with the mouse, and it’s supposed to control the capsule’s movement. So far it’s working perfectly except for one problem: The capsule is currently rotating on the Z axis, and I’d like it instead to rotate on the Y axis. That’s it.

Here is my extremely simple code for the joystick icon- it basically says “rotate toward the cursor and broadcast your rotation as ‘rotationraw’ for the capsule to see”.

Code (CSharp):

1.  
2.  
3. using System.Collections;
4.  
5. using System.Collections.Generic;
6.  
7. using UnityEngine;
8.  
9.  
10. public class LookAt : MonoBehaviour
11.  
12. {
13.  
14.     // This quaternion here is for the capsule to reference
15.  
16.     public static Quaternion rotationraw;
17.  
18.  
19.     // This public target is the cursor, placed manually in the Unity Editor
20.  
21.     public Transform target;
22.  
23.  
24.     void Update()
25.  
26.     {
27.  
28.         transform.right = target.position - transform.position;
29.  
30.         rotationraw = transform.rotation;
31.  
32.     }
33.  
34. }
35.  
36.  
37.  

Here is my extremely simple code for the capsule. It basically says “rotate like the joystick using that ‘rotationraw’ variable it’s broadcasting”.

Code (CSharp):

1.  
2.  
3.  
4. using System.Collections;
5.  
6. using System.Collections.Generic;
7.  
8. using UnityEngine;
9.  
10.  
11. public class PlayerMovement : MonoBehaviour
12.  
13. {
14.  
15.     void Update()
16.  
17.     {
18.  
19.         transform.rotation = LookAt.rotationraw;
20.  
21.     }
22.  
23. }
24.  

As you can hopefully see, the capsule is rotating just fine- I’d just like it to rotate left and right as opposed to up and down. I plan to use this to control the direction of the capsule as a rigid body in the very near future. Any and all help would be greatly appreciated.

 

Generally I stray away from eulerAngles, but your case is simple enough where this should just work, at least until the situation gets more complex

Code (CSharp):

1. transform.rotation = Quaternion.Euler(0, LookAt.rotationraw.eulerAngles.z, 0);

 

Thank you, cat. It worked. One day I'll actually take a math class and figure this out.

 

Don't encourage him. All he did was sit there with a look of detached disdain as I typed that answer out.
