Unity-EasyTouch插件之Two Finger

今天，我们来学习下多手指触摸屏幕的事件，分别有挤压（缩放），挤压（旋转）

 

挤压（缩放）：

在easytouch中，双手指挤压缩放的英文为Pinch

 

好了今天我们的测试是双手指挤压对物体进行缩放。我们测试的是Cube。

 

 

在easytouch中，分别有挤入（PinchIn）和挤出（PinchOut）这这两个对立的触屏手势。

using UnityEngine; using System.Collections;   public class TouchTest : MonoBehaviour {     void OnEnable(){         EasyTouch.On_PinchIn += On_PinchIn;//挤入         EasyTouch.On_PinchOut += On_PinchOut;//挤出         EasyTouch.On_PinchEnd += On_PinchEnd;//挤压结束     }           void OnDisable(){         UnsubscribeEvent();     }           void OnDestroy(){         UnsubscribeEvent();     }           // Unsubscribe to events     void UnsubscribeEvent(){         EasyTouch.On_PinchIn -= On_PinchIn;         EasyTouch.On_PinchOut -= On_PinchOut;         EasyTouch.On_PinchEnd -= On_PinchEnd;     }           void Start(){     }     private void On_PinchIn(Gesture gesture){           if (gesture.pickObject == gameObject){                           float zoom = Time.deltaTime * gesture.deltaPinch;                           Vector3 scale = transform.localScale ;             transform.localScale = new Vector3( scale.x - zoom, scale.y -zoom, scale.z-zoom);         }       }       private void On_PinchOut(Gesture gesture){         if (gesture.pickObject == gameObject){             float zoom = Time.deltaTime * gesture.deltaPinch;                           Vector3  scale = transform.localScale ;             transform.localScale = new Vector3( scale.x + zoom, scale.y +zoom,scale.z+zoom);           }     }     private void On_PinchEnd(Gesture gesture){                   if (gesture.pickObject == gameObject){             print ("End");         }               }   }

　　这里注意一下，挤压的时候两个手指必须都接触到GameObject，不能一只有一只没有。

 

可能有些小伙伴还不知道怎么在电脑上测试，在easytoucjh的属性面板里面，我们发现按下Left Alt是默认的Pinch和Twist的按键。

 

 

挤压（旋转）：

在easytouch中双手挤压旋转对应的英文为Twist
