我正在创建一个简单的 iPhone 游戏(但我所在的课程要求我使用 Flash ......),当我试图从游戏中删除对象时,我遇到了一个重大问题。
该游戏有点像一个动态的浪费时间的泡泡纸游戏,其中有无限的舞台“刷新”。一旦用户弹出所有气泡,就会随机生成更多。(当数组为空时,setup()
再次调用。)
现在,我通过代码从库中提取了五种不同颜色的气泡图形中的一种,并随机放置在舞台上。但是,我不喜欢重叠,所以我给了每个气泡一个小的方形命中空间,这样当它们随机放置并显着重叠时,它们会自行弹出。出于某种原因,当我试图去除它给我的气泡时
Error#2025 提供的 DisplayObject 必须是调用者的子对象。
我尝试将 stage 添加到addChild
and removeChild
,但我得到了同样的错误。
