You can’t run code within vs code. It’s not an IDE. If you want to use the debugger features like breakpoint then you’ll have to do it in studio. You can install various plugins in vs code to make the experience good though like linters and intellisenses for luau and stuff.
I wouldn’t use it, to be honest, just another thing you have to learn. There aren’t too many advantages, yet some may argue “Rojo” can help with saving scripts and that “TypeScript” helps a lot, but if your not willing to learn it or you already have other tools I wouldn’t recommend it. Honestly, you’d be better off with another editor. In all, there are many advantages and disadvantages, it’s basically trial and error, so it’s up to personal preference. I wouldn’t say I like it personally, but try fixing issues you have with it and if it works it works.
