Actionscript 3 AS 3：现有函数不'；没有找到？

我的程序编译中有一个奇怪的错误

对于我的程序场景，它只是一个MovieClip命名为“perso”，用键盘的箭头移动

Flash告诉我“键盘”和“动画”属性访问无法找到

我真的不明白

var perso:Perso = new Perso();

stage.addEventListener(KeyboardEvent.KEY_DOWN, clavierDown);
stage.addEventListener(KeyboardEvent.KEY_UP, clavierUp);
stage.addEventListener(Event.ENTER_FRAME, animation);

function clavierDown(e)
{
    switch(e.keyCode)
    {   
        case Keyboard.LEFT:
            perso.speedX = -speedHero;
            break;
        case Keyboard.RIGHT:
            perso.speedX = speedHero;
            break;
        case Keyboard.UP:
            perso.speedY = -speedHero;
            break;
        case Keyboard.DOWN:
            perso.speedY = speedHero;
            break;
    }

function clavierUp(e)
{
    switch(e.keyCode)
    {
        case Keyboard.LEFT:
            perso.speedX = 0;
            perso.scaleX = -1;
            break;  

        case Keyboard.RIGHT:
            perso.speedX = 0;
            perso.scaleX = 1;
            break;

        case Keyboard.UP:
            perso.speedY = 0;
            break;

            case Keyboard.DOWN:
            perso.speedY = 0;
            break;
    }
}

function animation(e)
{
    animeHero();
}

谢谢大家!

对不起，我刚刚错过了“clavierDown”函数末尾的右大括号…
