我是Action Script 3的初學者,目前正在開發彈跳球的基本遊戲。遊戲運行完美,彈跳球,並通過鼠標點擊改變方向,以及它的顏色。但是,現在我想進行一些改變,比如遊戲進行中;我希望球的尺寸很小,當比賽進行時,球會擴大。我已經在下面分享了我的代碼,具體來說,我需要在這一點上做。有什麼建議麼?更改Action Script 3遊戲中物體的大小
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
public class Main extends MovieClip {
private var ball:Ball = new Ball();
private var ballSpeed, cf: int;
private var isLeft, isUp, isLand: Boolean;
public function Main() {
// constructor code
createBall();
ballSpeed = 5;
isLeft = false;
isUp = false;
isLand = true;
cf = 1;
stage.addEventListener(Event.ENTER_FRAME, frameHandler);
stage.addEventListener(MouseEvent.CLICK, changeDirection);
}
private function changeDirection(m:MouseEvent){
if(isLand){
isLand = false;
} else {
isLand = true;
}
cf += 1;
if (cf > ball.totalFrames){
cf = 1;
}
ball.gotoAndStop(cf);
}
private function createBall(){
ball.x = stage.stageWidth * .5;
ball.y = stage.stageHeight * .5;
addChild(ball);
}
private function frameHandler(e:Event){
if(isLand){
if((ball.x + ball.width * .5) < stage.stageWidth && !isLeft) {
ball.x += ballSpeed;
}
if((ball.x + ball.width * .5) >=stage.stageWidth) {
isLeft = true;
}
if((ball.x - ball.height * .5) > 0 && isLeft) {
ball.x -= ballSpeed;
}
if((ball.x - ball.width * .5) <= 0){
isLeft = false;
}
}
if(!isLand){
if((ball.y + ball.height * .5) < stage.stageHeight && !isUp){
ball.y += ballSpeed;
