Keeping MonoBehavior alive during game scene switch?

[*Aqua*]

I noticed a MonoBehavior gets destroyed when the game scene is switched.

Is there a simple way (a flag maybe?) to keep it alive until the game shuts down?

Thanks! That was quick!

I'm not certain but you may also need to make sure that another one doesn't get created every time you switch. I think the "once" parameter on KSPAddon is meant for this purpose. I suggest adding some logging to your constructor, OnStart and OnAwake to make sure you're not getting lots of them...

Yep, I'm aware of that but it's good you mentioned that. Others might be interested in this topic too.

The MonoBehaviour is always destroyed at the end of a Scene when decorated with a KSPAddon decorator.

To prevent it from being destroyed, you need to Instance yours manually (sometimes it can be a good idea) or, better yet, do the following call on the Awake() callback:

internal void Awake()
{
	DontDestroyOnLoad(this.gameObject);
	// The rest of your code, if existent
}

You NEED to set the once parameter of the KSPAddon decotator to true, or you will have multiple instances of that MonoBehavirour in memory as the scenes changes!
