unity3d FingerGestures 单点 多点触摸 手势

Admin

FingerGestures最大的好处就是结合unity3d进行多点触控，手势识别，编写一次代码 ，通过配置来进行多平台发布FingerGestures提供了3种不同的方法来检测由用户执行的拖动手势。

• [color=#02bb8 !important]方法1：使用默认的手势事件
  
  • 每个手指的手势事件：为每个单独的手指，独立的状态
    
    • OnFingerTap
    • OnFingerDoubleTap
    • OnFingerSwipe
    • OnFingerLongPress
    • OnFingerDragBegin，OnFingerDragMove，OnFingerDragEnd
      
  • 全局手势事件：
    
    • 当一个手指触摸屏幕上：
      
      • OnTAP
      • OnDoubleTap
      • OnSwipe
      • OnLongPress
      • OnDragBegin，OnDragMove，OnDragEnd
        
    • 两个手指触摸屏幕时：
      
      • OnPinchBegin，OnPinchMove，OnPinchEnd
      • OnRotationBegin，OnRotationMove，OnRotationEnd
      • OnTwoFingerTap
      • OnTwoFingerSwipe
      • OnTwoFingerLongPress
      • OnTwoFingerDragBegin，OnTwoFingerDragMove，OnTwoFingerDragEnd
        
      
      
    
    
• [color=#02bb8 !important]方法2：使用一个DragGestureRecognizer
• [color=#02bb8 !important]方法3：使用“工具箱”
  工具箱是一种更高级方便的方式，设计的理念是开箱就用，包括了很多脚本，但是没有涉及到核心源码，所以不用的话  可以把这个包直接删掉
  

FingerGestures  的事件注册是基于c＃的，性能还是可以

FingerGestures is a scripting package forUnity that lets you easily detect and react to common input gesturesperformed with either a mouse or a touch screen device, using one ormore fingers.
Main Features

• Single and multi-finger gesture recognizers for Drag, Tap, Swipe, Long-Press, Pinch, Rotate
• Finger events: Down, Up, Move, Stationary
• An easy and smooth integration with Unity’s workflow
• A straightforward and streamlined event-driven API to quickly get started without digging too deep
• A rich and powerful object-oriented gesture framework for maximum control
• An efficient, low memory usage implementation
• Finger/Touch abstraction: mouse and touchscreen inputs go through the same pipe!
• A Toolbox packed with no-coding-required & ready-to-use scripts including:
• Drag & drop system
• Smooth orbit camera using drag and pinch gestures to rotate, zoom and pan
• Pinch-Zoom camera
  

Several easy-to-follow sample scenes that will progressively introduce you to the libraryWorks on desktop, iOS and Android platformsSupport for both Javascript and C#Includes full C# source code with comments and online documentation
