我不知道如何描述这个问题，但我会尽量清楚。我正在做一个动作脚本练习，其中我有一个定义为 Sprite 的 DisplayObjetct 容器，我想要添加随机无线电长度在 50 到 100 之间的随机圆圈。
名为“gameZoneContainer_sp”的容器已添加到 Main 类的显示列表中，每次用户更改舞台大小时，容器都会设置其新的宽度和高度值。
这是我所说的代码：
私有函数 refreshScreen(ev:Event= null ):void{
// Remember: we can know stage dimensions accessing to:
// stage.stageWidth
// stage.stageHeight
//CONSTANTS DEFINITION OF MARGIN
const margen:Number=25;
//LOCAL VARIABLES DEFINITION
var cercleWidth:Number, cercleHeight:Number;
var invaderWidth:Number, invaderHeight:Number;
var containerWidth:Number, containerHeight:Number;
var logoWidth:Number, logoHeight:Number;
//STORING DIMENSIONS
cercleWidth=addCercle_bt.width;
cercleHeight=addCercle_bt.height;
invaderWidth=addInvader_bt.width;
invaderHeight=addInvader_bt.height;
containerWidth=gameZoneContainer_sp.width;
containerHeight=gameZoneContainer_sp.height;
logoWidth=logoUOC_sp.width;
logoHeight=logoUOC_sp.height;
//SET HORIZONTAL POSITION OF THE ELEMENTS
addCercle_bt.x=(stage.stageWidth/2)+margen;
addInvader_bt.x=(stage.stageWidth/2)-(invaderWidth+margen);
gameZoneContainer_sp.x=margen;
logoUOC_sp.x=stage.stageWidth-(logoWidth+margen);
//SET VERTICAL POSITION OF THE ELEMENTS
addCercle_bt.y=stage.stageHeight - (cercleHeight+margen);
addInvader_bt.y=stage.stageHeight-(invaderHeight+margen);
gameZoneContainer_sp.y=logoHeight+margen*2;
logoUOC_sp.y=margen;
//SET DIMENSIONS OF CONTAINER gameZoneContainer_sp
gameZoneContainer_sp.width=stage.stageWidth-(margen*2);
gameZoneContainer_sp.height=stage.stageHeight-(margen*4)-invaderHeight-logoHeight;
}
/* THIS METHOD ADD A CIRCLE TO THE CONTAINER gameZoneContainer_sp */
private function addCercle(ev:MouseEvent):void {
// Create new instance of Cercle
// and add it to gameZoneContainer_sp
//CONSTANT DEFINITIONS
const minRadio:Number=50, maxRadio:Number=100;
//LOCAL VARIABLES DEFINITIONS OF RADIO, COLOR AND CIRCLE
//THE RADIO CHOOSE A RANDOM VALUE BETWEEN 50 AND 100
var radio:Number=minRadio+(maxRadio-minRadio)*Math.random();
var color:uint=Math.random() * 0xFFFFFF;
var cercle:Cercle=new Cercle(color,radio);
//
var minPosX:Number=radio;
var maxPosX:Number=gameZoneContainer_sp.width/2;
var minPosY:Number=radio;
var maxPosY:Number=gameZoneContainer_sp.height-(minPosY);
// SET POSITION OF THE CIRCULE INSIDE THE CONTAINER
cercle.x= minPosX + (maxPosX-(2*minPosX))*Math.random();
cercle.y= minPosY + (maxPosY-(2*minPosY))*Math.random();
cercle.drawCercle();
gameZoneContainer_sp.addChild(cercle);
refreshScreen(ev);
//TRACING RESULTS...
trace ("Added cercle!");
trace ("alto del contenedor: "+gameZoneContainer_sp.height);
trace ("Posicion x: "+cercle.x);
trace ("radio: "+radio);
}
//DEFINITION OF THE CIRCLE CLASS
public class Cercle extends Sprite {
private var _color:uint;
private var _radio:Number;
public function Cercle(color:uint,radio:Number){
super();
/* THE CLASS ACCEPT HEX VALUES.*/
_color= color;
_radio=radio;
init();
}
public function init():void{
drawCercle ();
}
//METHOD TO DRAW A CIRCLE
public function drawCercle():void{
var circle:Shape=new Shape();
circle.graphics.beginFill(_color,1);
circle.graphics.drawCircle(0,0,_radio);
addChild(circle);
}
}
这是我的问题：当我添加一个圆圈时，它似乎没问题，直到我改变窗户（场景）的尺寸。每次我更新尺寸时，事件都会从主类执行方法 refreshScreen 更新场景中所有元素的尺寸和位置，但之后如果我添加一个新圆圈，它会更改容器，这是错误的，因为我想要的是在容器中添加圆圈。
希望不会太久。请任何帮助都会很棒！先感谢您！！
