Cocos2d-x removeChild works wierd

Cocos2d-x removeChild works wierd

本文关键字：wierd works removeChild Cocos2d-x      更新时间：2023-10-16

我已经有这行代码

for (auto view : views)
{
    view->update(deltaTime);
    if (view->isDead())
    {
        trash.push_back(view);
        removeChild(view, true);
    }
}

它在removeChild(view, true);线路上破裂。

这是我的堆栈跟踪。

我无法从我那里得到想要的东西。它称为视图破坏者，仅此而已！bam！崩溃！视图的破坏者是空的，我完全迷失了。

我敢打赌，您多次将代码称为代码。

然后，在调用removechild（视图，true）后，自动视图已被删除，并且您没有从视图中删除视图。当然，当您进行Trice时，该程序将崩溃，因为您正在尝试删除已删除的视图。

如果我的猜测是错误的，则需要发布更多代码。

P.S：您的代码样式在COCOS2D-X中不是很好。您无需像Java那样收集垃圾。您需要在Cocos2D-X中研究内存管理。
