Scripts
Write Luau the Roblox way, press F5 and watch it play. Stop, and whatever your scripts changed goes back.
No script runs in Edit. F5 runs them all; ShiftF5 puts back what they wrote, made or drew, and keeps your own edits.
Help as you type
Completion, hints and type errors know every instance in your project.
Luau's own type checker, as in Roblox Studio, rechecks a script a moment after each edit; hover an underline for its message.
Where code lives
Share code in modules, play it in InitScripts, build with ToolScripts.
A ToolScript runs once when you press Run, and its changes are real: saved, and one undo step.
| ModuleScript | Required by other scripts |
| InitScript | Runs in Play and in renders |
| ToolScript | Runs once on Run; what it changes is kept |
| TypeScript | Types made from the modules that point at it |
| Sandbox | A scope with its own Luau VM |
| Script layers | A video layer that returns function(time) |
| Tasks | task.spawn, delay, wait, RunService.Heartbeat, on play time |
Type less
Type ! and a word to drop in a require, a path or a CFrame.
Most read the Explorer's selection: select a module and !selected writes its require line.
!module | Every module this script may require |
!selected | Require the selected module |
!reference | The selected instance's path |
!cook | Read the selected Cook track |
!CFrame | The selected instance's CFrame |
!b Name | A bookmark banner |
!class Name | A class with new and Destroy |
