detect when scene has loaded into view ?

I’m pressing a button, going to a new scene and performing some intense calcs for a couple of seconds.

However, what’s happening is I’m pressing the button, going the new scene, the calc begins and the screen doesn’t get drawn

So, is there a way of checking if the scene has loaded, before starting my calc ?

I know I could insert a small timer delay, but was hoping for something a bit more eloquent? [import]uid: 97524 topic_id: 26774 reply_id: 326774[/import]
