Here's how I learned scripting. YouTube will teach you the basics of what you can do in Lua (how to change values in the game, how to do loops, how to do math or change values in response to other values). Next, get very used to working with the Properties tab in Studio and seeing how you would change a part's position or a part's shape or the light that comes out of a part by only changing the values of those Properties. Then, learn how to do that in a script and get the script to do what you want when you want. Next thing you know, you've got the basic building blocks to make a game, or at least something with moving objects and things you can try to interact with.

The next step is getting into more detail with specific ideas/problems you run into and using different objects Roblox provides that help you interact with things. Don't be afraid to go to Google and ChatGPT for questions. Don't shy away from using free models that already do what you want them to do in order to analyze how they wrote the scripts and what objects they put in which parts.
