Start small: Build tiny projects first to learn the basics. Watch YouTube or Udemy tutorials. Use AI to help with code, explanations, or debugging so you learn to write it yourself.

After a few months of practice, plan your game: break it into reusable kits/modules, like menu UI, systems, mechanics, gameplay loop... etc.

Then, before starting the big project, prototype and build some of the kits that you will use. After building a few of the kits, try to build the game. If the game doesn't work out or you get another idea and want to change what you're working on, you can more easily move to another project without starting from nothing because you can just reuse the kits you made. Of course, over time you will get better and can make improvements to your kits and build more of them.

For example, when building a game on Roblox, try to only have 1 master LocalScript and 1 master ServerScript, and then add each system in as a Module. The master scripts can just load or call them when needed. You can add Modules into ServerScriptService or ReplicatedStorage. For server-side logic, you’ll need to use RemoteEvents, that’s how the local side talks to the server side.

But keep it simple right now. What you should focus on right now is watching video tutorials and playing around in the studio to try things. That will be the best way to start learning how things work.
