Chuck 操纵杆控制答案

【问题描述】：

我正在尝试接收来自操纵杆的输入。收到输入后应产生声音。这有效，但它响应操纵杆按钮的按下和释放。如何让它只响应推送而不响应发布。

更重要的是，如何让事件侦听器响应操纵杆的 180 度移动。目前，当我移动操纵杆时，它继续产生声音，即使在我释放它很久之后

 Hid myHid;

HidMsg msg;

0=>int device;

if(!myHid.openJoystick(device)){
<<<"Couldn't">>>;
me.exit();
}

<<<"Ready">>>;

SndBuf coin=>dac;
  0.6=>coin.gain;
0=>coin.pos;



while(1){

    myHid=>now;
    while(myHid.recv(msg)){
        <<<"Rev">>>;

        me.dir()+"/audio/smw_jump.wav"=> coin.read;
        .2::second=>now;


        }

    }
