Roblox scripting guides

Complete, working Luau for the systems Roblox developers build most, with where each script goes, why it is written that way and the errors you are likely to hit. Every guide works by hand. RoCode, our Studio AI agent, is there if you would rather describe the system and have it built in your place.

Or let RoCode write it in your place.

Every guide here works by hand. RoCode is the shortcut: describe the system, and it writes the Luau and builds it in the place you have open.
