我正在为我在大学的课程制作一个 Flash 游戏，我一直在学习一个教程，但为了我自己的缘故一直在把它改掉。我撞到的一堵墙是，当我发射一颗子弹时，它只会向右侧发射，上下移动一点，我一直试图修复它一段时间，但没有任何反应，也没有任何作用。
包裹 {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
public class Wizard extends MovieClip {
private var dx:Number;
private var dy:Number;
private var Bulletspeed:int;
public var Angle:Number;
public var newAngle:Number;
var shotCoolDown:int;
const MAX_COOLDOWN=20;
public function Wizard() {
//constructor
//Shot cool down
shotCoolDown=MAX_COOLDOWN;
addEventListener(Event.ENTER_FRAME, update);
//set up an event listener for when the turret is added to stage
addEventListener(Event.ADDED_TO_STAGE, initialise);
}
function initialise(e:Event) {
//reduce shot cool down by one
shotCoolDown=shotCoolDown-1;
//add a click listener to the stage
stage.addEventListener(MouseEvent.CLICK, fire);
}
function fire(m:MouseEvent) {
//Able to shoot
if (shotCoolDown<=0) {
//resets cool down
shotCoolDown=MAX_COOLDOWN;
//spawn bullet
var B = new Bullet();
//set position and rotation of the bullet
B.rotation=rotation;
B.x=x;
B.y=y;
//add the bullet the the wizard
parent.addChild(B);
}
}
function update():void {
//Shot cool down
shotCoolDown--;
//Make the Wizard face the mouse
if (parent!=null) {
dx=stage.mouseX-this.x;
dy=stage.mouseY-this.y;
Math.abs(dx);
Math.abs(dy);
var Angle=Math.atan2(dy,dx);
var newAngle = Angle * (180 / Math.PI);
if ((0 < newAngle) && (newAngle <= 90)) {
gotoAndPlay("Right");
} else if ((90 < newAngle) && (newAngle <= 180)) {
gotoAndPlay("Down");
} else if ((-180 < newAngle) && (newAngle <= -90)) {
gotoAndPlay("Left");
} else if ((-90 < newAngle) && (newAngle <= 0)) {
gotoAndPlay("Up");
}
this.rotation=Angle;
}
}
}
}
那是我的玩家类的代码，包括子弹发射等等。我想我知道问题所在，我需要将其链接到向导更新的其余部分。但我不知道如何，如果需要，这是我的子弹课。
包裹 {

}
function update (e:Event) {
//Move in the direction the bullet is facing
x=x+Math.cos(rotation/180*Math.PI)*speed;
y=y+Math.sin(rotation/180*Math.PI)*speed;
//Clears bullet once it leaves the stage
if (x<0 || x>500 || y<0 || y>500) {
//removes the update listner
removeEventListener(Event.ENTER_FRAME, update);
parent.removeChild(this);
}
