Does every roblox studio update change something?

Everytime I watch a scripting tutorial, even from 2 weeks ago whenever I copy paste everything it just does not work.

Make sure every variable in the script exists in your game (like an object), and check for spelling mistakes.

Copying scripts is bad practice you need to learn the lua language and syntax first.

Where would I find those? I’d like to read up on them

I also take some free models from tool box and try to read the scripts on them

Free models are mostly old scripts which could contain deprecated terms.

Use this for the Roblox API:
