Unity基础（11）-Input类

获取鼠标屏幕位置
Vector3  MousePos = Input.MousePosition;

屏幕触摸手机位置状态：
FingerId : 手指编号，整型
Phase:手指的阶段，枚举类型。分为几个阶段：Begin:开始接触屏幕; Moved:移动Stationary ： 静止；Ended：手指离开屏幕；Canceled:系统关闭触控
Position : 手指触碰屏幕的位置，Vector2类型。坐标以屏幕左下角为原点1像素对应一个位置
// 遍历输出所有的Touch
Foreach(Touch touch in Input.touches)
{
    GUILayout.Lable(string.Format(“手指:{0}状态:{1}位置:{2}”,touch.fingerId,touch.phase.ToString(),touch.position));
}

关于重力感应：
Acceleration,即加速度传感或者重力感应。可以通过Input.acceleration得到重力感应的值Vector3,值域[-1，1]

其他API:
Input.deviceorientation 得到当前游戏对运行的朝向
Input.touchSupported 得到当前游戏是否支持手指触控操作
Input.mutiTouchEnable ：可以设置游戏是否支持多点触控。

        h = Input.GetAxis("Horizontal");
        v = Input.GetAxis("Vertical");
        利用虚拟轴进行移动

         h1 = Input.GetAxis("Horizontal1");
