Lua 调用第二个场景时，第一个场景不会消失。卢阿
我试图调用我的第二个场景，让第一个场景完全消失。第二个场景中的对象正在出现，但它们与第一个场景中的对象重叠。我尝试手动调用scene.hide和scene.destroy函数，还尝试将对象添加到组中。奇怪的是，有些对象在添加到组中时不可见，但其他对象却可见。请帮忙！另外，很抱歉，只有部分代码在单独的框中，但我不知道如何修复它Lua 调用第二个场景时，第一个场景不会消失。卢阿,lua,coronasdk,Lua,Coronasdk,我试图调用我的第二个场景，让第一个场景完全消失。第二个场景中的对象正在出现，但它们与第一个场景中的对象重叠。我尝试手动调用scene.hide和scene.destroy函数，还尝试将对象添加到组中。奇怪的是，有些对象在添加到组中时不可见，但其他对象却可见。请帮忙！另外，很抱歉，只有部分代码在单独的框中，但我不知道如何修复它 function scene:create( event ) local sceneGroup = self.view display.setStatus
