unity3d与android开发真实手柄连接

尝试过AS转写手柄监听、incontrol插件，最终没能实现。手柄型号：SP3/PC。

经过一夜奋战，通过https://blog.csdn.net/lengyoumo/article/details/91386404文章指示，

在edit ->projectsettings->input->axes中设定
type 选择joystick axis
axis 选择 x axis 和 y axis 。分别对应 horizontal 和 vertical。
如果手柄有多个摇杆，需要修改name和 axis。

 

（附：Unity Input的手柄映射）

 

 

 

修改了Dead、Sensitivity的值，不然转的头晕，速度太快，而且人物不停的朝一个方向转。。。把Vertical做了镜像（invert)，好像这个轴跟U3d的3rdCControler方向是反的。Horizontal就不用了。

通过https://blog.csdn.net/cordova/article/details/51036547的方法进行了测试，目前代码如下：

public class TVInput : MonoBehaviour {

    public Text KeyCodeText;               //显示按键状态的text文本
    public Text KeyCodeText1;

    
    private bool isOk;                     //确定键按下状态

   

    // 初始化
    void Start()
    {
        isOk = false;
    }

    // 按帧刷新检测
    void Update()
    {

        //监听按键事件：
        //*** 按下 ***//
        //左
        if (Input.GetKeyDown(KeyCode.LeftArrow))
        {
            isLeft = true;
            KeyCodeText.text = "左键按下";
        }
        //右
        if (Input.GetKeyDown(KeyCode.RightArrow))
        {
            isRight = true;
            KeyCodeText.text = "右键按下";
        }

        //上
        if (Input.GetKeyDown(KeyCode.UpArrow))
        {
            isUp = true;
            KeyCodeText.text = "上键按下";
        }

        //下
        if (Input.GetKeyDown(KeyCode.DownArrow))
        {
            isDown = true;
            KeyCodeText.text = "下键按下";
        }

        //返回
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            isBack = true;
            KeyCodeText.text = "返回键按下";
        }

        //回车
        if (Input.GetKeyDown(KeyCode.JoystickButton0))    //A
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton0按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton1))    //B
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton1按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton2))     //X
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton2按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton3))    //Y
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton3按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton4))   //L1
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton4按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton5))   //R1
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton5按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton6))   //L2
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton6按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton7))    //R2
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton7按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton8))    //左摇杆
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton8按下";
        }
        
        if (Input.GetKeyDown(KeyCode.JoystickButton9))   //右摇杆
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton9按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton10))   //START
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton10按下";
        }
        if (Input.GetKeyDown(KeyCode.JoystickButton11))  //SELECT
        {
            isOk = true;
            KeyCodeText.text = "JoystickButton11按下";
        }

    }
}

在电视端测试通过。

Stationary Turn Speed 减到20，这转速还是太快。

注意：发布前将mobile input屏蔽掉，否则可能会引起真实手柄失效。

关于GetAxis函数调用如下参考：

    // Use this for initialization
    void Start () {
        IsMenu = false;
        menuCanMove = true;
        MenuIndex = 0;
        SndIndex = 0;
    }
    
    // Update is called once per frame
    void Update () {
        if (Input.GetKeyUp(KeyCode.JoystickButton11))  //SELECT
        {
