How to rotate towards mouse on y axis only? 3D

[ayockel90]

I’m using the below code to rotate my player to face the mouse position.

It sort of works but how can I constrict it to the Y axis only?

Vector3 direction = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
Quaternion desiredRotation = Quaternion.LookRotation(direction);
transform.rotation = Quaternion.Slerp(transform.rotation, desiredRotation, 10 * Time.deltaTime);

Hello @ayockel90,

How about you save the value of transform.rotation before changing it and only apply the y to your rotation by making a temporary variable which take x and z from your initial rotation and the desired y:

Quaternion rotation = transform.rotation; // save the current rotation
Quaternion desiredRotation = Quaternion.LookRotation(direction);
Quaternion newRotation = Quaternion.Euler(rotation.eulerAngles.x, desiredRotation.eulerAngles.y, rotation.eulerAngles.z);
transform.rotation = Quaternion.Slerp(rotation, newRotation, 10 * Time.deltaTime); // apply the new rotation
