public static bool isPlaying ;

説明

Returns true when called in any kind of built Player, or when called in the Editor in Play Mode (Read Only).

In a built Player, this method will always return true.

In the Editor, it will return true if the Editor is in Play Mode.

Note: In the Editor for ScriptableObject assets, this property will return false in OnEnable. After reloading the domain, when reloading assemblies, Unity invokes OnEnable on all ScriptableObject instances. This happens before isPlaying is set to true.
