get_isPlaying is not allowed to be called during serialization

I get this error during build creation:
get_isPlaying is not allowed to be called during serialization, call it from Awake or Start instead.
It's because Application.isPlaying is used from an OnValidate() event handler.

If Application.isPlaying is not allowed to be called, what is the current supported way of determining if we are in play mode or not?

(This is used with code that has to run when the player changes some properties on the fly - so putting it in Awake or Start is obviously not an option.)

 

Hi

You can use EditorApplication.playmodeStateChanged to listen for play mode enter/exit events.
