因为没法修改,请需要的朋友自己将键盘监听那段替换为以下内容:
document.body.addEventListener(keydown function(e) { if ((e.keyCode == 87 || e.keyCode == 38) && that.dir != D) { that.dir = U } else if ((e.keyCode == 83 || e.keyCode == 40) && that.dir != U) { that.dir = D } else if ((e.keyCode == 65 || e.keyCode == 37) && that.dir != R) { that.dir = L } else if ((e.keyCode == 68 || e.keyCode == 39) && that.dir != L) { that.dir = R } } false)回复
吃两个后,然后按反方向 会卡 住
