TCastleScene.WasVisible has children but is not returning True about castle-engine HOT 3 CLOSED

Found my problem with Children not having WasVisible

I was calling it in Render rather than Update :(

Of course, in Render, it won't have been set yet it seems as swithcing to Update fixed it

from castle-engine.

Hmm : Testing TCastleScene(ActiveScene.Items[0]).WasVisible actually also returned false so maybe there's another problem?

It's a deliberate feature that TCastleScene.WasVisible doesn't check whether children scenes are visible. The general rule is:

• TCastleScene-specific features (like this WasVisible) do not care/apply to children scenes.
• Only TCastleTransform features (like TCastleTransform.Exists) apply to children as well.

I know it's not ideal (it would be easier to say "everything affects children" or "nothing affects children"), but this is a practical situation that is flexible and comfortable, so we'll keep this.

I see the docs have not been clear about it, fixed.

I tested examples\viewport_and_scenes\test_was_visible\, it correctly changes WasVisible. Please submit a testcase if this doesn't work for you.
