How to rotate towards Z axis

Hi guys i have this script
using UnityEngine;
using System.Collections;
[DisallowMultipleComponent]


public class edrotscript : MonoBehaviour {



float rotSpeed = 20;

void OnMouseDrag()


{
float rotX = Input.GetAxis("Mouse X")*rotSpeed*Mathf.Deg2Rad;
float rotY = Input.GetAxis("Mouse Y")*rotSpeed*Mathf.Deg2Rad;

transform.RotateAround(Vector3.up, -rotX);
transform.RotateAround(Vector3.right, rotY);
}
that helps me rotate gameobject towards X and Y axis with mouse drag does someone have idea how i can rotate the gameobject towards Z axis. Thank you

 

Well assuming that the Z axis is going into and out of the screen Rotating in the Z-Axis would just "spin in place" so basically the entire world view in front of you would spin around. Like Holding a camera in your hand pointing forward and just spinning it in a circle.

If thats what your going, you just going to need another set of inputs. In a 3D world mouse can only give you two inputs (up/down and left/right). so you could just pick two keys like Z/X to spin clockwise and counterclockwise. Another option is to dual purpose the Mouse X movement by either seeing if its the left or right mouse button (left would be your normal code, right would be the Z-Axis spin). Finally you also check if ctrl or alt is held down while they have the mouse movement and that woudl change the X-axis to a Z-axis rotation

 

Sorry i didn't quite get that so what im trying to do is rotate the gameobject clock like when i drag the mouse i don't need to be able to rotate it on X and Y i just post the code as example. Can you please edit it in the code. Thank you

 

Code (CSharp):

1. float rotX = Input.GetAxis("Mouse X")*rotSpeed*Mathf.Deg2Rad;
2. float rotY = Input.GetAxis("Mouse Y")*rotSpeed*Mathf.Deg2Rad;
3.  
4. if (Input.GetKeyDown(KeyCode.RightControl || Input.GetKeyDown(KeyCode.LeftControl)
5.     transform.RotateAround(Vector3.forward, -rotX);
6. else
7.     transform.RotateAround(Vector3.up, -rotX);
8. transform.RotateAround(Vector3.right, rotY);

This is exactly like your code but if the control key is held down it rotates in the z-axis instead.
if you just need your code to rotate just use Vector3.forward like you'd use up or right, and the angle is however much you want it rotated.
