GUIs and Script's?

How do i make a GUI and script?

Go to Starter Gui, right click and press "Insert Basic Object" Then Press ScreenGUI and Insert it. Then do the right click again and add a text Box or button or label. Its a little complicated so look for tutorials on youtube. :) I had the same problem as you. But if you look at my game its fully fledged!

This question is really broad, and cannot simply be answered in a short matter. For instance, there are different types of GUI's: Screen GUI's, Surface GUI's, etc.

I advise you to read the wiki about GUI's here.

If you're asking how to insert GUI's and scripts into your place, go into Studio, click on View < Basic Objects, and you'll be able to see all the objects you are able to insert.

If you're a total beginner at scripting, read the wiki as well. Beginner's tutorial
