Mouse WheelScroll

Can someone explain how Mouse WheelScroll axis work as i have tried multiple different scripts & solutions i found on the internet but nothing works all i need is to make an object rotate on Y axis to right when wheel is scrolled up and left if wheel is scrolled down

Once i can figure it out i will implement it in my game in which i can already pick up objects and able to hold object with Q (temp use input) but i want to be able to spin object model using Mouse WheelScroll up/down to rotate object so i can get a view of the objects model from all sides.

Rotation explanation:
Wheel up = Rot right
Wheel down = Rot left




all advice will be appreciated!
Thanks in advance!

 

? anyone ?

 

You can get the mouse scroll wheel information using standard Unity inputs. By using Input.GetAxis("MouseScrollWheel"), you can determine how much the mouse wheel was turned.

Here's is some simple code I used to make a basic cube rotate around the Y axis. You need to drag and drop the object you want to rotate into the "whatToRotate" field.

Code (CSharp):

1.     public class MouseWheelRotation : MonoBehaviour
2.     {
3.         // The object you want to rotate.  I used a simple cube.
4.         public GameObject whatToRotate;
5.  
6.         // A speed modifier to tune how fast the object rotates as the mouse wheel turns.
7.         public float rotationSpeed = 100.0f;
8.  
9.  
10.         void Start ()
11.         {
12.             if (whatToRotate == null)
13.             {
14.                 Debug.Log("WARNING:  No object to rotate.");
15.             }
16.         }
17.  
18.      
19.         void Update ()
20.         {
21.             // Get the amount the mouse wheel moved from the standard Unity Input.
22.             float _rotation = Input.GetAxis("Mouse ScrollWheel");
23.  
24.             // Rotate the object based on the given input.
25.             //   Vector3.up is because you want to rotate around the Y axis.
26.             //   _rotation is how much input was recieved.
27.             //   rotationSpeed is a modifier speed up the rotation.
28.             //   -1.0f is needed for mousewheel up to rotate to the right.
29.             //
30.             //   Space.World is so that the object rotates in world space around the Y axis.
31.             //   Leave that out if you want the object to rotate around it's personal Y axis.
32.             whatToRotate.transform.Rotate(Vector3.up * _rotation * rotationSpeed * -1.0f, Space.World);
33.         }
34.     }
35.

I tried this, and it seems to work:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class MouseScroll : MonoBehaviour {
5.  
6.     public float scrollSpeed = 100f;
7.  
8.     // Update is called once per frame
9.     void Update () {
10.         float scrollAmount = Input.GetAxis ("Mouse ScrollWheel");
11.         this.transform.Rotate (Vector3.up, -scrollAmount * scrollSpeed);
12.  
13.     }
14. }
