ChucK操纵杆控件

Question

我正在尝试接收来自操纵杆的输入。在接收到输入之后，应该会生成声音。这是有效的，但它对按下和释放操纵杆的按钮都有反应。我如何让它只响应推送而不响应释放。

更重要的是，我如何让事件侦听器对操纵杆的180度移动做出响应。目前，当我移动操纵杆时，它会继续发出声音，即使在我释放它很长时间之后也是如此

 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;


        }

    }
