How do you script on Roblox

You have to learn Lua first. The best place to learn is from the Roblox Wiki. My favorite article is 'The Absolute Beginners Guide to Scripting'. It is very helpful. You can also learn Lua from Lua reference manuals. Yet another way you can learn is by dissecting free models and looking over the scripts inside, trying to understand what the script does. But be careful when using free models, for they can infect you place and completely destroy it. (Note: Infecting scripts do not effect you computer, only your game on Roblox) To insert a new script, click Tools in the top left corner, a whole bunch of tools will pop up at the top of your screen. Then, go to the top of your screen, and click the Insert. Next, click Object. A window will appear in the middle of the screen. Find Script, click it, then click Ok.

Also there are many websites out there made specifically for learning Roblox Lua. To see one of the better but incomplete sites out there look at the related links.
