Tomorrow, I'm going to stop being lazy and finish User Interfaces

[Jacob__mybb_import1]

It's similar to the way you create UIs in Java. Add UIFrames to the player's PlayerUI (name may be changed), then add buttons, labels, and images to the frames. Buttons will have a MouseDown event that you can use to make them do things when they are clicked.

Giving a player the initial UI for your game will be done from a PlayerAdded script.
