AS3层顺序
我创建了两个空的 Sprite 作为图层，bottom_spr 和 top_spr
单击按钮时，会出现一个 MovieClip 并跟随您的鼠标，直到您单击，那么它的位置就固定了。
单击该按钮后，我会将 MovieClip 添加到正确的 Sprite 中。
不幸的是，图层系统不起作用，因为它们按照我放置的顺序分层，精灵似乎不会影响它。
这怎么可能？
private var ground_spr:Sprite;
private var units_spr:Sprite;
public function Game() {
addEventListeners();
ground_spr = new Sprite();
units_spr= new Sprite();
addChild(ground_spr);
addChild(units_spr);
}
private function addEventListeners(){
groundBtn.addEventListener(MouseEvent.CLICK, clickGroundBtn);
unitBtn.addEventListener(MouseEvent.CLICK, clickUnitBtn);
}
private function clickGroundBtn(event:MouseEvent){
var ground = new Ground_mc();
follow();
ground_spr.addChild(ground);
}
private function clickUnitBtn(event:MouseEvent){
var unit = new Unit_mc();
follow();
units_spr.addChild(unit);
}
I created two empty Sprites to serve as layers, bottom_spr and top_spr
When clicking a button, a MovieClip appears and follows your mouse, untill you click, then its position is fixed.
As soon as the button is clicked, I addChild the MovieClip to the correct Sprite.
Unfortunately, the layer system doesn't see to work, because they are layered in the order I place them, the Sprites don't seem to influence it.
How is this possible?
private var ground_spr:Sprite;
private var units_spr:Sprite;
public function Game() {
addEventListeners();
ground_spr = new Sprite();
units_spr= new Sprite();
addChild(ground_spr);
addChild(units_spr);
}
private function addEventListeners(){
groundBtn.addEventListener(MouseEvent.CLICK, clickGroundBtn);
unitBtn.addEventListener(MouseEvent.CLICK, clickUnitBtn);
}
private function clickGroundBtn(event:MouseEvent){
var ground = new Ground_mc();
follow();
ground_spr.addChild(ground);
}
private function clickUnitBtn(event:MouseEvent){
var unit = new Unit_mc();
follow();
units_spr.addChild(unit);
}

你的问题很模糊，但我会尽力回答。如果您明确说明您希望如何准确订购物品，我可以更好地回答您的问题。如果需要的话，可以在深度处理上添加抽象层。在这种情况下，我认为没有太大必要，但我会向您展示一些您可以做的事情。

Your question is very vague but I will attempt to answer it. If you clarify how you want your objects ordered exactly, I can better answer your question. It is fine to add layer of abstraction over the depth handling, if you need it. In this case I dont see much of a need, but I will show you a few things you could do.
