Roblox Player

Roblox Player is the Roblox game client that is the core aspect of playing games on the platform. The Client’s GUI has changed over the past decade.

Client 2006-2008
When Roblox was released out of beta in 2006 the client was very simple and had a game editing tool embedded into the client, which is now known as Roblox Studio. Very little aspects escaped from the original client that remain in the current client GUI; (such as the “reloading” cursor, however this was later tweaked a bit).

A first big revision
In 2009 the GUI within the client had a huge overhaul. This overhaul focused more on simplicity on boarders and chat bubbles, as well as adding NPCs in games, that had their own independent chat GUI. This also added the functionality to snapshot the client.

The 2011 Client
In 2011 the GUI was overhauled completely, This added the ability to record the client, aside adding to screenshotting. This also comepletely overhauled the Player list for the first time. This was also the first time Builders Club badges were visible in the Player List. The Backpack was also overhauled.

Current Client (2015-present)
This was the latest overhaul of the GUI back in 2015. This overhauled the whole appearance of the client, such as the Chat window, Player list and Hotbar/Backpack GUI. Ever since 2015 small changes have occurred in the client since then.

Trivia
