2 Questions about making intro?

1. I am want to display frame from GUI on top layer, so ZIndex equals 10. Also I have information gui in left down corner with lower ZIndex, but it anyway displays on the top. Why?
2. How to prevent character from spawning? I want to show intro first.

I don't understand what's going on with your first question. My only idea is that you might not have given every part of the gui the same ZIndex. Ex, if you have a TextButton parented to a Frame and the Frame has ZIndex 10 but the TextButton has ZIndex 1, then the TextButton will be behind all other controls with ZIndex > 1; you have to set the TextButton's ZIndex to 10 also.

As for #2, you need to set Players.CharacterAutoLoads to false. The link has a sample script of how to load the character yourself; you'll have to modify it to delay the first spawn until your intro is done.
