我正在做一个飞机的小游戏，
在最顶的超类是关于所有的飞机，包括敌机和我方的机，共同的属性是
health,
body(就是飞机的外观),
side(决定它是我方的机还是敌机)
deep,
level(就是把创建出来的飞机控制在一个范围的层次里面)
所以这一段代码是这样的：
function Planes(health,body,side,deep,level){
//创建飞机
function new_plane(body,side,deep,level) {
_root.attachMovie(body,string(side)+deep,deep++)//这里那个命名 的格式我觉得有点问题~
deep=deep%level+level
return _root[string(side)+deep]
}
this.MainBody=new_plane(body,side,deep,level)
this.MainBody.health=health //把生命属性放在影片里面，不知道有没有问题？
}
//接下我是这方飞机的子类；
function defender(body,side,deep,level){
this.planes=planes;
this.planes(body,side,deep,level)
this.side="defender"
}
defender.prototype=new planes()
function enemy(body,side,deep,level){
this.planes=planes;
this.planes(body,side,deep,level)
this.side="enemy"
}
enemy.prototype= new planes();

//创建的时候
planes=new defender("plane","defender",_root.deep)
enemy1= new enemy("ene1","enemy",_root.ene_depth,40)

现在的问题是很奇怪啊，这样子创建实例的时候都要加入side 属性，我不想每次都要创建实例都要输入一次，想在子类中获取的side属性，然后怎么办？

类的继承在as1.0里可以这样:

function car() {
	this.a = "blue";
}
function bus() {
	this.people = 20;
}
bus.prototype = new car();
mycar=new bus();
trace(mycar.a);

你这个太乱了。_root.attachMovie(body,string(side)+deep,deep++)这里应该也有问题。

Ps.继承的好像不能用变量.你先自己试试吧。我最近没空搞这些东东。可能要过两天才会来，到时再说吧

期待？
是叫你自己做啊，还等我给你做？

没时间啊。
给你一个我原来做的东东，也许有用。是个纯AS的小游戏
你自己研究一下吧,祝你做出好东东

急急！加入文字后，文件变得非常大，怎样解决呢？谢谢
