好吧,我已经坚持了大约三个小时了,我终于想寻求帮助了。
基本上,当我的玩家飞船与其中一个敌人接触时,我试图从屏幕上移除所有敌方对象实例,因为他随后失去了生命并被放回屏幕上的安全位置。
编辑:这是我的 Enemy Dude .as 文件中的所有代码,可能有点过分,但无论如何。
package
{
import flash.display.MovieClip;
import flash.events.*;
import flash.media.Sound;
import flash.media.SoundChannel;
public class Enemydude extends MovieClip
{
private var _root:Object;
private var speed:int = 6;
private var shipps = this
public function Enemydude()
{
addEventListener(Event.ADDED, beginclass);
addEventListener(Event.ENTER_FRAME, entFrame);
}
private function beginclass(event:Event):void
{
_root = MovieClip(root);
}
private function entFrame(event:Event):void
{
x -= speed;
if(this.x < -64)
{
removeEventListener(Event.ENTER_FRAME, entFrame);
_root.removeChild(this)
}
if(_root.gameover)
{
x = -700
removeEventListener(Event.ENTER_FRAME, entFrame);
removeEventListener(Event.ADDED, beginclass);
}
for (var i:int = 0; i<_root.playerBulletContainer.numChildren; i++)
{
var bulletTarget:MovieClip = _root.playerBulletContainer.getChildAt(i)
if (hitTestObject(bulletTarget))
{
removeEventListener(Event.ENTER_FRAME, entFrame);
_root.removeChild(this);
_root.playerBulletContainer.removeChild(bulletTarget);
bulletTarget.removeListeners();
_root.Score += 10
makeExplosion();
}
}
if(hitTestObject(_root.mcship))
{
makeExplosion();
shipPos();
removethis();
}
}
private function makeExplosion()
{
var sndExplode:snd_explosion1;
var sndExplodeChannel:SoundChannel;
sndExplode=new snd_explosion1();
sndExplodeChannel=sndExplode.play();
var newExplosion01:explosionEffect=new explosionEffect ;
newExplosion01.x=this.x;
newExplosion01.y=this.y;
_root.explosionContainer.addChild(newExplosion01);
}
private function shipPos()
{
_root.lives -= 1;
_root.mcship.x = 80;
_root.mcship.y = 225;
for each(var i:Enemydude in _root.enemies)
{
removethis();
}
_root.enemies.length = 0;
}
public function removethis():void
{
if(parent) parent.removeChild(this)
removeEventListener(Event.ENTER_FRAME, entFrame);
}
}
}
编辑:这是我现在拥有的与我的主要时间线中的 Enemydude 相关的代码,对此我深表歉意。
var enemies:Array = [];
var Shipheight:Number = 300;
var Enemytime:int = 0;
var Enemylimit:int = 16;
if (Enemytime<Enemylimit)
{
Enemytime ++;
}
else
{
var newEnemy01 = new Enemydude();
newEnemy01.y = Shipheight;
newEnemy01.x = stage.stageWidth + 64;
addChild(newEnemy01);
enemies.push(newEnemy01);
Enemytime = 0
function shipY(event:Event):void
{
Shipheight = Math.ceil(Math.random()* 250) + 80;
}
提前感谢您的帮助,如有任何建议,我们将不胜感激。
最佳答案
我建议将你的敌人存储在一个数组中。
例如,创建数组enemies
:
var enemies:Array = [];
然后将您的代码修改为:
else
{
var newEnemy01 = new Enemydude();
newEnemy01.y = Shipheight;
newEnemy01.x = stage.stageWidth + 64;
addChild(newEnemy01);
enemies.push(newEnemy01);
Enemytime = 0;
}
这样你就可以使用这个新数组移除所有敌人:
for each(var i:Enemydude in enemies)
{
i.remove(); // Or whatever function Enemydude has to remove itself.
}
// Empty the enemies Array.
enemies.length = 0;
这是您可以为 Enemydude
创建的 .remove()
方法:
public function remove():void
{
if(parent) parent.removeChild(this);
// Remove any event listeners etc from this object.
}
