Objects not moving - Actionscript

Question

我正在製作一款遊戲，其中您的飛機是試圖躲避來襲的導彈。我試圖讓我的壞蛋產生並從舞臺的頂部移動到底部。目前沒有錯誤，壞人產卵但不移動。請幫忙。

import flash.utils.Timer; 
import flash.events.TimerEvent; 

var upPressed:Boolean = false; 
var downPressed:Boolean = false; 
var leftPressed:Boolean = false; 
var rightPressed:Boolean = false; 
var baddies:Array = new Array(); 
var baddieSpeed:int = 15; 
var timer: Timer = new Timer(1000); 
timer.addEventListener(TimerEvent.TIMER, addBaddie); 
timer.start(); 

//deg2rad = Math.PI/180; 
//rad2deg = 180/Math.PI; 

plane.addEventListener(Event.ENTER_FRAME, fl_MoveInDirectionOfKey_2); 
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_SetKeyPressed_2); 
stage.addEventListener(KeyboardEvent.KEY_UP, fl_UnsetKeyPressed_2); 



function fl_MoveInDirectionOfKey_2(event:Event) 
{ 
    if (upPressed) 
    { 
     plane.y -= 8;

function getAngle(x1:Number, y1:Number, x2:Number, y2:Number):Number { 
    var radians:Number = Math.atan2(y2 - y1, x2 - x1); 
    return rad2deg(radians); 
} 

Answer 1

它看起來像你調用這個兩次：

timer.addEventListener(TimerEvent.TIMER, addBaddie);

我建議你創建一個專用於移動的敵人定時器：

var baddieMover:Timer = new Timer(40); 
baddieMover.addEventListener(TimerEvent.TIMER, moveBaddies); 
baddieMover.start(); 
var counter:int = 0; 
function moveBaddies(evt:TimerEvent):void { 
    for (var i:int = 0; i < baddies.length; i++) { 
     var dx = Math.cos(deg2rad(baddies[i].angle)) * baddies[i].speed; 
     var dy = Math.sin(deg2rad(baddies[i].angle)) * baddies[i].speed; 
     baddies[i].x += dx; 
     baddies[i].y += dy; 
    } 
} 

Answer 2

我相信你已經忘了調用Movebaddies函數。正如EgoAnt所說 - 爲了保持整潔，我建議你爲這個功能製作一個新的Listener。
