Copy something that works

Working scripts for the things people actually build. Every one is complete: copy it onto an object and it runs.

Never done this before? Start with Your first script, then come back.

Things you click and walk into#

Doors and switchesA door that opens, closes itself, or is driven by a switch across the room.Triggers and zonesGreeters, pressure plates, checkpoints, hazards.Moving thingsLifts, platforms, patrols, conveyors, projectiles.

Things players hold#

Pickups and carryingPick it up, pose it, put it down, hand out copies.Weapons and combatA complete weapon: recoil, cone, ammunition, reloading.Poses and animationsMake a pose in the animator and play it on somebody.Damage and destructionBreakable props, player health, respawning.

Talking to players#

Menus and HUDsPanels, pages, live numbers, world prompts.Shops and currencyA counter, a balance, goods that reach a hand.Scores and rewardsA shared leaderboard, a daily reward, a round on a clock.

The world itself#

Effects and atmosphereFire, smoke, lamps, weather, storms.Sound and musicOne-off noises, loops, distance, ambience.Terrain and blocksSculpting ground, mining, generated structures.Building and survivalPieces players raise, support, resources that regrow.

Plumbing#

Saving dataWhat survives a restart, and how to store it.Talking between scriptsEvents, public channels, tags.Sharing codeOne module every script in the world can require.

Five habits worth copying#

They show up in nearly every recipe here.

Check before you use. Anything that can answer nil deserves the check, and the shape is always the same:

Luau

local part = self:part("hinge")if not part then return end

Ask the engine, do not remember. self:held_at(), player.holding, self:get(...). A local copy of the world's state goes stale the moment something happens by a route your script does not run.

Act on the change, not on the tick. A timer that writes the same properties every second spends the region's budget for nothing.
