Unity 小科普

老规矩，先介绍一下 Unity 的科普小知识：

• Unity是 实时3D互动内容创作和运营平台 。
• 包括游戏开发、美术、建筑、汽车设计、影视在内的所有创作者，借助 Unity 将创意变成现实。
• Unity 平台提供一整套完善的软件解决方案，可用于创作、运营和变现任何实时互动的2D和3D内容，支持平台包括手机、平板电脑、PC、游戏主机、增强现实和虚拟现实设备。
• 也可以简单把 Unity 理解为一个游戏引擎，可以用来专业制作游戏！

Unity 实用小技能学习

Unity InputSystem拿到触摸屏幕的坐标,鼠标的坐标等

在Unity的新输入系统InputSystem中，获取键盘鼠标的API发生了变化，不再是之前用Input.就可以拿到了。

本文将在InputSystem中获取键盘鼠标的新API做一个简单总结整理。

键盘相关
键盘事件监听

void Update()

     if (Keyboard.current.spaceKey.wasPressedThisFrame)
     
         Debug.Log("空格键按下");
     
     if(Keyboard.current.aKey.wasReleasedThisFrame)
     
         Debug.Log("A键抬起");
     
     if(Keyboard.current.spaceKey.isPressed)
     
         Debug.Log("空格按下");
     
     if(Keyboard.current.anyKey.wasPressedThisFrame)
     
         Debug.Log("任意键按下");
     

键盘事件绑定

    void Start()
    
        Keyboard.current.onTextInput += (c) =>
        
            Debug.Log("通过Lambda表达式" + c);
        ;
        Keyboard.current.onTextInput += KeyboardInput;
    

    private void KeyboardInput(char c)
    
        Debug.Log("监听" + c);

鼠标相关：

鼠标坐标

void Update

	if(Mouse.current.rightButton.wasPressedThisFrame)
    
        Debug.Log("鼠标右键按下");
    
    if(Mouse.current.middleButton.wasPressedThisFrame)
    
        Debug.Log("鼠标中建按下");
    
    if(Mouse.current.forwardButton.wasPressedThisFrame)
    
        Debug.Log("鼠标前键按下");
    
    if(Mouse.current.backButton.wasPressedThisFrame)
    
        Debug.Log("鼠标后键按下");
    
    
    //获取鼠标屏幕坐标(左下角为（0,0)
    Debug.Log(Mouse.current.position.ReadValue());
    //两帧之间的偏移
    Debug.Log(Mouse.current.delta.ReadValue());
    //获取鼠标滚轮坐标
    Debug.Log(Mouse.current.scroll.ReadValue());

鼠标事件绑定

    void InputTest()
    
        GameInput inputAction = new GameInput();//GameInput为场景中的InputSystem控制器
        inputAction.Enable();

        inputAction.Gameplay.MouseDown.performed += ctx =>
        
            Debug.Log("按下：" + UnityEngine.InputSystem.Mouse.current.position.ReadValue());
        ;

        inputAction.Gameplay.MouseDrag.performed += ctx =>
        
            Debug.Log("拖拽：" + UnityEngine.InputSystem.Mouse.current.position.ReadValue());
        ;
        inputAction.Gameplay.MouseUp.performed += ctx =>
        
            Debug.Log("抬起：" + UnityEngine.InputSystem.Mouse.current.position.ReadValue());
        ;
    

触摸屏相关

void Update

	Touchscreen ts = Touchscreen.current;
	if (ts == null)
	
	 	return;
	
	else
	
		 TouchControl tc = ts.touches[0];
		 if(tc.press.wasPressedThisFrame)
		 
		      Debug.Log("按下");
		 
		 if(tc.press.wasReleasedThisFrame)
		 
		      Debug.Log("抬起");
		 
		 if(tc.press.isPressed)
		 
		      Debug.Log("按住");
		 
		 if(tc.tap.isPressed)
		 
		
		 
		 //点击次数 
		  Debug.Log(tc.tapCount);
		 //点击位置
		  Debug.Log(tc.position.ReadValue());
		 //第一次接触位置
		  Debug.Log(tc.startPosition.ReadValue());
		 //得到的范围
		  Debug.Log(tc.radius.ReadValue());
		 //偏移位置
		  Debug.Log(tc.delta.ReadValue());
		 //返回TouchPhase: None,Began,Moved,Ended,Canceled,Stationary
		  Debug.Log(tc.phase.ReadValue());
	
	 //判断状态
		 UnityEngine.InputSystem.TouchPhase tp = tc.phase.ReadValue();
		 switch (tp)
		 
		     //无
		     case UnityEngine.InputSystem.TouchPhase.None:
		         break;
		         //开始接触
		     case UnityEngine.InputSystem.TouchPhase.Began:
		         break;
		         //移动
		     case UnityEngine.InputSystem.TouchPhase.Moved:
		         break;
		         //结束
		     case UnityEngine.InputSystem.TouchPhase.Ended:
		         break;
		         //取消
		     case UnityEngine.InputSystem.TouchPhase.Canceled:
		         break;
		         //静止
		     case UnityEngine.InputSystem.TouchPhase.Stationary:
		         break;
		 

手柄相关

Gamepad handle = Gamepad.current;

    if(handle==null)
    
        return;
    
   
    Vector2 leftDir= handle.leftStick.ReadValue();//左手柄坐标
    Vector2 rightDir= handle.rightStick.ReadValue();//右手柄坐标
    
    //左摇杆按下抬起
    if(Gamepad.current.leftStickButton.wasPressedThisFrame)
    
    
    if (Gamepad.current.leftStickButton.wasReleasedThisFrame)
    
    
    if (Gamepad.current.leftStickButton.isPressed)
    
    
    //右摇杆按下抬起
    if (Gamepad.current.rightStickButton.wasPressedThisFrame)
    
    
    if (Gamepad.current.rightStickButton.wasReleasedThisFrame)
    
    
    if (Gamepad.current.rightStickButton.isPressed)
    
    

    if(Gamepad.current.dpad.left.wasPressedThisFrame)
    
    
    if (Gamepad.current.dpad.left.wasReleasedThisFrame)
    
    
    if (Gamepad.current.dpad.left.isPressed)
    
    
    
    //右侧三角方块/XYAB按键
    //Gamepad.current.buttonEast;
    //Gamepad.current.buttonWest;
    //Gamepad.current.buttonSouth;
    //Gamepad.current.buttonEast;
    if (Gamepad.current.buttonNorth.wasPressedThisFrame)
    
    
    if (Gamepad.current.buttonNorth.wasReleasedThisFrame)
    
    
    if (Gamepad.current.buttonNorth.isPressed)
    
    
    //手柄中央键
    if(Gamepad.current.startButton.wasPressedThisFrame)
    
    
    if(Gamepad.current.selectButton.wasPressedThisFrame)
    
    
    //肩键
    if(Gamepad.current.leftShoulder.wasPressedThisFrame)
    
    
    if (Gamepad.current.rightShoulder.wasPressedThisFrame)
    
    
    if(Gamepad.current.leftTrigger.wasPressedThisFrame)
    
    
    if(Gamepad.current.rightTrigger.wasPressedThisFrame)
