Roblox Data Stores: Save Player Progress With Lua

Players expect their progress to be waiting for them when they come back. This four-week intermediate course shows learners how Roblox games save data using DataStoreService.

In week one learners review leaderstats and set up a simple coin system. Week two introduces data stores, where learners write code that saves a player's coins when they leave and loads them when they join again. In week three they save more than one value, such as level, experience and a favorite color setting, by storing a table. The final week focuses on doing it safely. Learners wrap their save code in protected calls so the game does not break when saving fails, and they learn why testing in a published place matters.

The teacher explains each concept with clear diagrams of what happens when a player joins and leaves a server, then live-codes the solution. Learners build the system into their own game and test it by leaving and rejoining. Throughout the course learners also learn good habits like naming data keys clearly and only saving what is needed.

This course is best for learners aged ten and up who are comfortable with functions, tables and events. By the end they will have a game that remembers each player's progress, an essential skill for anyone who wants to publish a real Roblox game.

How classes work

Each class combines a diagram-based explanation with guided coding. Learners test saving and loading in their own place and troubleshoot with the teacher's help.

What we'll cover

• Week 1: Leaderstats Review – Set up a coin system that players can see.

• Week 2: Saving and Loading – Save coins when players leave and load them when they return.

• Week 3: Saving Tables – Store level, experience and settings together in one table.

• Week 4: Safe Saving – Use protected calls and test saving in a published place.

Comfortable with Lua functions, tables and events. Learners need a Roblox account that can publish places.
