包路径：com.jme3.scene.Spatial
类名称：Spatial
方法名：requiresUpdates

Spatial.requiresUpdates介绍

[英]Set to true if a subclass requires updateLogicalState() even if it doesn't have any controls. Defaults to true thus implementing the legacy behavior for any subclasses not specifically turning it off. This flag should be set during construction and never changed as it's supposed to be class-specific and not runtime state.
[中]如果子类需要updateLogicalState（），即使它没有任何控件，也设置为true。默认值为true，从而实现任何子类的遗留行为，而不是专门将其关闭。这个标志应该在构造期间设置，并且永远不会更改，因为它应该是特定于类的，而不是运行时状态。
