01-Unity下的Input类属性
属性
- 常用属性
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。02-Unity下的Input类方法
圣典翻译
代码语言：javascript复制 h = Input.GetAxis("Horizontal");
v = Input.GetAxis("Vertical");
利用虚拟轴进行移动
PlayerA.transform.Translate(h * 10f * Time.deltaTime, 0, v * 10f * Time.deltaTime;);03-Input虚拟轴的设置
虚拟轴的设置
04-Input类的封装
代码语言：javascript复制void Update () {
h1 = Input.GetAxis("Horizontal1");
v1 = Input.GetAxis("Vertical1");
MoveObjRun(PlayerB,h1,v1);
}
// 箭头控制移动方法
private void MoveObjRun(GameObject player,float v1,float h1)
{
IfRange(KeyCode.UpArrow, player,new Vector3(0, 0, v1));
IfRange(KeyCode.DownArrow, player, new Vector3(0, 0, v1));
IfRange(KeyCode.LeftArrow, player, new Vector3(h1, 0, 0));
IfRange(KeyCode.RightArrow, player, new Vector3(h1, 0, 0));
}
peivate void IfRange(KeyCode c,GameObject player,Vector3 v3)
{
if (Input.GetKey(c))
{
TransLateObj(v3, player);
}
}
private void TransLateObj(Vector3 v,GameObject player)
{
player.transform.Translate(v);
