轻量级键盘控制实现原理（转）

在AS2.0时代Flash的键盘控制有2种方式，1）key.isDown(code: Number) 和key.isUp(code: Number) 。2)键盘侦听Key.addListener(ax.text = " 上+右";
break;
case "1100" :
ax.text = " 上+左";
break;
case "0011" :
ax.text = " 下+右";
break;
case "1001" :
ax.text = " 下+左";
break;
case "1010" :
ax.text = " 左+右";
break;
case "0101" :
ax.text = " 上+下";
break;
case "1000" :
ax.text = " 左";
break;
case "0100" :
ax.text = " 上";
break;
case "0010" :
ax.text = " 右";
break;
case "0001" :
ax.text = " 下";
break;
}
}
