The first time I used ROBLOX Studio I just placed tons of free models for no reason into my game. Then I started to "try" to modify the scripts inside them or at least to guess how they worked (I just changed "integers", which means "numbers" in programming and some "strings", which means "text" in programming, although I didn't modify important things.)
Then I searched up for tutorials on youtube, and I watched these vids (Be careful, they are old and some things are deprecated, which means some things do not work same anymore, but if you only watch these tutos you will have no prob with that.)
Then I started investigating by myself. I looked up for random things at wiki.roblox.com , and I eventually got better. And I ended up knowing how to script (Or so I think).
I also made a tutorial about debugging, you could take a look at it.
By the way, you can skip the free models investigating part. But always investigate by yourself. That is very important. Never stop investigating, discovering things you didn't know. That is the most important thing when learning to script; to discover by yourself. And you can watch other videos if you want, I just said how I got started. I just took a little boost with those tutorials and then I progressed by myself.
Good luck! I love it when someone is interested in scripting and asks for help. It's great, have no doubt in asking for help! It is also really important. Good luck!
