前一半是
AS3，后一半是AS2。大家觉得有用的话帮我顶啊，谢谢~！！！
AS3：Bullet.as,BulletMove.as,Control.as,Enemy.as,Plane.as,AS3就写了一点，没写完，感觉写不下去了，希望大虾提点建议啊。
BulletMove.as
复制内容到剪贴板
代码:
package{
import flash.display.Sprite;
import flash.events.Event;
public class BulletMove extends Sprite{
private var _speed:int=10;
public function BulletMove(){
var bullet:Bullet=new Bullet(5,0xffff00ff);
addChild(bullet);
addEventListener(Event.ENTER_FRAME,bulletMove);
}
public function bulletMove(event:Event):void{
event.target.y-=_speed;
}
}
}Control.as:

plane.x=250;
plane.y=350;
var enemy:Enemy=new Enemy(20,20,0xff0000ff);
enemy.x=Math.random()*400+30;
enemy.y=Math.random()*50+20;
addChild(enemy).name="enemys";
_planeBulletSprite=new Sprite();
addChild(_planeBulletSprite);
addEventListener(Event.ENTER_FRAME,planeEnterFrame);
}
public function planeEnterFrame(event:Event):void{
stage.addEventListener(KeyboardEvent.KEY_DOWN,onKeyDownEvent);
}
public function onKeyDownEvent(event:KeyboardEvent):void {
if(event.keyCode==Keyboard.UP){
getChildByName("planes").y-=_speed;
}
if (event.keyCode==Keyboard.DOWN) {
getChildByName("planes").y+=_speed;
}
if(event.keyCode==Keyboard.LEFT){
getChildByName("planes").x-=_speed;
}
if(event.keyCode==Keyboard.RIGHT){
getChildByName("planes").x+=_speed;
}
if(event.keyCode==Keyboard.SPACE){
bulletSend();
}
}
public function bulletSend():void{
var bullet:BulletMove=new BulletMove();
_planeBulletSprite.addChild(bullet).name="bullets";
bullet.x=getChildAt(0).x+45;
bullet.y=getChildAt(0).y-15;
if(getChildByName("enemys").hitTestObject(_planeBulletSprite)){
removeChild(DisplayObject(getChildByName("enemys")));
var enemy:Enemy=new Enemy(20,20,0xff0000ff);
enemy.x=Math.random()*400+30;
enemy.y=Math.random()*50+20;
addChild(enemy).name="enemys";
}
}
}
}感觉AS3写的碰撞检测很延迟啊，过一段时间后才能删去啊。。。。
下面是AS2：
as2压缩
文件里分了5步来写飞机
游戏，代码里有注释很详细的。
