Question

不幸的是，我不是一个程序员，只是一个艺术家，但我必须做一个小游戏示例作为我的大学作业。

所以，我为我的名为Hero的movieclip做了一个课程，我在Hero.as中制作了控制系统（来自教程）。它运作良好，但英雄正在旋转，因为我还没有设置它。这是Hero.as的一部分：

package AS {

import flash.display.MovieClip;
import flash.events.KeyboardEvent;
import flash.events.Event;


public class Hero extends MovieClip {

    private var moveUp: Boolean;
    private var moveLeft: Boolean;
    private var moveDown: Boolean;
    private var moveRight: Boolean;
    private var moveSpeed: uint;

    public function Hero() {
        init();
    }

    protected function init() {
        moveUp = false;
        moveLeft = false;
        moveDown = false;
        moveRight = false;
        moveSpeed = 5;

        Constants.stageRef.addEventListener(KeyboardEvent.KEY_DOWN, keyPressedListener);
        Constants.stageRef.addEventListener(KeyboardEvent.KEY_UP, keyReleasedListener);
        Constants.stageRef.addEventListener(Event.ENTER_FRAME, frameListener);
    }

    //when you press down a key
    private function keyPressedListener(e: KeyboardEvent) {
        var key: uint = e.keyCode;
        if (key == 87 || key == 38) { //go to up with W or UP
            moveUp = true;
        } else if (key == 65 || key == 37) { //go to left with A or LEFT
            moveLeft = true;
        } else if (key == 83 || key == 40) { //go to down with S or DOWN
            moveDown = true;
        } else if (key == 68 || key == 39) { //go to right with D or RIGHT
            moveRight = true;
        }
    }

    //Blablabla

Game.fla中的this is how the Hero movieclip looks like。问题是我不知道如何在Hero.as中使用gotoAndStop（）。首先，我必须阻止英雄的旋转 - gotoAndStop（“StandFront”） - 然后我必须在每个部分（在keyPressedListener中）设置英雄应该走的正确方向。 这就是我用错误的代码思考它的方式，也许是在错误的地方：

        protected function init() {
        gotoAndStop("StandFront");   //------------Stop the character's spinning
        moveUp = false;
        moveLeft = false;
        moveDown = false;
        moveRight = false;
        moveSpeed = 5;

        //Blablabla...

    //when you press down a key
    private function keyPressedListener(e: KeyboardEvent) {
        var key: uint = e.keyCode;

        if (key == 87 || key == 38) { //go to up with W or UP
            moveUp = true;
            gotoAndStop("WalkFront"); //--------------- Play the animation where the
                                      //character's moving up while the player's
                                      //pressing the key W or UP.
        }
        //Blablablabla...

我不认为它是否有用，但这里是Main.as我作为一个类附加到Game.fla文档：

package AS {
    import flash.display.MovieClip;

    public class Main extends MovieClip {

        private var hero:Hero;


        public function Main() {
            init();
        }

        public function init(){
            Constants.stageRef=stage;

            hero=new Hero();
            hero.x=300;   //512;
            hero.y=300;   //418.9;
            stage.addChild(hero);
        }
    }
}

非常感谢您的帮助！
