Question by Jeeva3m · Oct 19, 2016 at 05:16 AM · c#gameobjectanglemouse-dragmousedown

How to set Minimum and Maximum angles on Drag to Rotate Gameobject ??

Hello Friends, I'm trying to create a demo on a product that has to be rotated by mouseClick both x and y but with Minimum and Maximum angles. The following script helps in rotating Gameobject but dont know how to control the rotation angles while mouse dragging. Any help or other ways to do it. (Note: dont want to use camera rotation or orbit).

(Script by @MattiasWargren)

  using UnityEngine;
  using System.Collections;
  
  public class ObjectRotator : MonoBehaviour 
  {
      
      private float _sensitivity;
      private Vector3 _mouseReference;
      private Vector3 _mouseOffset;
      private Vector3 _rotation;
      private bool _isRotating;
      
      void Start ()
      {
          _sensitivity = 0.4f;
          _rotation = Vector3.zero;
      }
      
      void Update()
      {
          if(_isRotating)
          {
              // offset
              _mouseOffset = (Input.mousePosition - _mouseReference);
              
              // apply rotation
              _rotation.y = -(_mouseOffset.x + _mouseOffset.y) * _sensitivity;
              
              // rotate
              transform.Rotate(_rotation);
              
              // store mouse
              _mouseReference = Input.mousePosition;
          }
      }
      
      void OnMouseDown()
      {
          // rotating flag
          _isRotating = true;
          
          // store mouse
          _mouseReference = Input.mousePosition;
      }
      
      void OnMouseUp()
      {
          // rotating flag
          _isRotating = false;
      }
      
  }
