How do I build a TARDIS?

As I'm sure many Doctor Who fans know, Darkspine DP removed his TARDIS flight some time ago, and since, people have been making more versions to fill the void. I'm one of those people, I've completed building everything but TARDISes and really need some help on scripting one.

I've done very basic scripting, and I mean very basic. I'm happy to script the TARDIS myself, but I just can't find the right tutorials anywhere online and that's really why I need some help. Here's what I want the TARDIS to do:

• Demat/take off leaver - click, TARDIS exterior takes off to the Vortex
• Either a screen GUI or different buttons - Choose landing location, TARDIS then lands
• GUI in which player can fly the TARDIS manually through an external camera to exterior

I've asked many people on Roblox, but as I said - I can't find anyone who can help. I know this group is against me just saying "Do it for me" and I don't want that - I don't have scripts in my game unless I understand how they work, otherwise I'll get lag and screen GUI's popping up everywhere and I'll have no idea how to remove them. I ideally want one of two things:

• Either someone come on board as an admin/creator for the scripting side - BUT I want to know how the script works.
• Or and more ideally, someone just point me in the right direction of the scripting tutorials I'd require.

This sounds very pathetic after some of the questions I see on here, but help would be very much appreciated.

Feel free to look at my game, too - just for some insight.
