[Solved] Rotate sphere on mobile with slide movement

Hi everyone !

So I have a little problem and I need your help !!

I have to rotate my object with a slide movement with my finger. On my pc it's working well (the movement is very fluid) but on mobile I have a little problem.
Here the script :

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class RotatePortals: MonoBehaviour
6. {
7.    public Transform target;
8.    public float distance = 2.0f;
9.    public float xSpeed = 20.0f;
10.    public float ySpeed = 20.0f;
11.    public float yMinLimit = -90f;
12.    public float yMaxLimit = 90f;
13.    public float xMinLimit = -90f;
14.    public float xMaxLimit = 90f;
15.    public float distanceMin = 10f;
16.    public float distanceMax = 10f;
17.    public float smoothTime = 2f;
18.    float rotationYAxis = 0.0f;
19.    float rotationXAxis = 0.0f;
20.    float velocityX = 0.0f;
21.    float velocityY = 0.0f;
22.  
23.    private Vector3 _mouseReference;
24.    private Vector3 _mouseOffset;
25.  
26.    // Use this for initialization
27.    void Start()
28.    {
29.        Vector3 angles = transform.eulerAngles;
30.        rotationYAxis = angles.y;
31.        rotationXAxis = angles.x;
32.        // Make the rigid body not change rotation
33.        if (GetComponent<Rigidbody>())
34.        {
35.            GetComponent<Rigidbody>().freezeRotation = true;
36.        }
37.    }
38.    void LateUpdate()
39.    {
40.  
41.        if (target)
42.        {
43.            _mouseOffset = (Input.mousePosition - _mouseReference);
44.  
45.            if (Input.GetMouseButton(0))
46.            {
47.                velocityX += xSpeed * (_mouseOffset.x + _mouseOffset.y) * distance * 0.02f;
48.                velocityY += ySpeed * Input.GetAxis("Mouse Y") * 0.02f;
49.            }
50.            rotationYAxis += -velocityX;
51.            rotationXAxis -= -velocityY;
52.            rotationXAxis = ClampAngle(rotationXAxis, yMinLimit, yMaxLimit);
53.            rotationYAxis = ClampAngle(rotationYAxis, xMinLimit, xMaxLimit);
54.            Quaternion fromRotation = Quaternion.Euler(transform.rotation.eulerAngles.x, transform.rotation.eulerAngles.y, 0);
55.            Quaternion toRotation = Quaternion.Euler(rotationXAxis, rotationYAxis, 0);
56.            Quaternion rotation = toRotation;
57.  
58.            //distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel") * 5, distanceMin, distanceMax);
59.            //RaycastHit hit;
60.            //if (Physics.Linecast(target.position, transform.position, out hit))
61.            //{
62.            //distance -= hit.distance;
63.            //}
64.            //Vector3 negDistance = new Vector3(0.0f, 0.0f, -distance);
65.            //Vector3 position = rotation * negDistance + target.position;
66.  
67.            transform.rotation = rotation;
68.            _mouseReference = Input.mousePosition;
69.            //transform.position = position;
70.            velocityX = Mathf.Lerp(velocityX, 0, Time.deltaTime * smoothTime);
71.            velocityY = Mathf.Lerp(velocityY, 0, Time.deltaTime * smoothTime);
72.  
73.        }
74.    }
75.    public static float ClampAngle(float angle, float min, float max)
76.    {
77.        if (angle < -360F)
78.            angle += 360F;
79.        if (angle > 360F)
80.            angle -= 360F;
81.        return Mathf.Clamp(angle, min, max);
82.    }
83.  
84.    void OnMouseDown()
85.    {
86.  
87.        // store mouse position
88.        _mouseReference = Input.mousePosition;
89.    }
90. }
91.  
92.  

The problem is that when I click on my screen the object rotate. It's like when I click on X = 150 the object rotate for have Rotation X = 150. On the PC it's not a problem, the object rotate only when I do a slide movement.

So I found a script who works well but it's not the good movement (not fluid, not smooth), and I can't mix them together for have what I want !!
Here this script :

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Rotate_Test : MonoBehaviour {
7.  
8.     #region ROTATE
9.     private float _sensitivity = 1f;
10.     private Vector3 _mouseReference;
11.     private Vector3 _mouseOffset;
12.     private Vector3 _rotation = Vector3.zero;
13.     private bool _isRotating;
14.  
15.     #endregion
16.  
17.     void Update()
18.     {
19.         if(_isRotating)
20.         {
21.             // offset
22.             _mouseOffset = (Input.mousePosition - _mouseReference);
23.             // apply rotation
24.             _rotation.y = -(_mouseOffset.x + _mouseOffset.y) * _sensitivity;
25.             // rotate
26.             gameObject.transform.Rotate(_rotation);
27.             // store new mouse position
28.             _mouseReference = Input.mousePosition;
29.         }
30.     }
31.     void OnMouseDown()
32.     {
33.         // rotating flag
34.         _isRotating = true;
35.         // store mouse position
36.         _mouseReference = Input.mousePosition;
37.     }
38.     void OnMouseUp()
39.     {
40.         // rotating flag
41.         _isRotating = false;
42.     }
43. }

Someone had an idea for mix them ? That's will be great !!

Have a nice day !

 

Insert at line 43 in the first script something like so:

Code (csharp):

1. if (Input.GetMouseButtonDown(0))  // only fires on the frame that the button goes DOWM
2. {
3.   // captures the current reference so it is "zeroed out"
4.   _mouseReference = Input.mousePosition;
5. }

Just be sure that happens BEFORE you calculate _mouseOffset.

 

Ho, thanks a lot !! It's working well .

Thanks again !!
