So, I'd like to point out, this is NOT how this forum is meant to be used. You should give some code which you've previously worked out, and then people will help you fix it.

We're not a website for users to just ask for entire projects, that's just lazy.

Please in future try and do something yourself first before asking..

In reference to what you asked, if you checked ROBLOX's wiki, you'd find this: http://wiki.roblox.com/index.php?title=Custom_loading_screen
