On [[Roblox]], the '''development''' of a [[place]] carried out by one or more [[User|users]], known as '''developers''', is a process mainly of designing, [[building]], [[Script|scripting]], testing and publishing places for other users to visit. The process is facilitated by [[Roblox Studio]], an [[wikipedia:Integrated development environment|IDE]] developed by the [[Roblox Corporation]]. Developers may also use other software used in the process. The [[engine]] is based on [[Class|classes]] that can be used by developers to design different aspects of the place. Often, monetization is also carried out by developers to earn [[Robux]], using means such as [[Pass|passes]], [[Developer product|developer products]] or [[paid access]], as well as marketing such as sponsoring or [[Advertisements|advertising]] to reach more users on the platform.

== Engine ==
The engine has many classes that can be used by developers to create and design different aspects of the place.
* [[Part]]s ({{Class link|BasePart}}) are the building blocks of the place's 3D [[Part#World|world]] ({{Class link|Workspace}}). Building is the process of assembling parts.
** [[Class:Humanoid|Humanoid]] is used to make [[Character|characters]] that can move without using other physical forces.
** [[Terrain]] ({{Class link|Terrain}}) is a deformable voxel-based mesh representing real-life [[wikipedia:Terrain|terrain]].
* [[Lighting]] has its properties, and most of them are controllable through the [[Class:Lighting|Lighting]] [[service]]. Lighting includes these global effects which belong to the lighting [[Lighting#Environment|environment]]:
** {{Class link|Sky}} allows changing the [[Lighting#Sky|sky]] including its [[wikipedia:Skybox (video games)|skybox]] as well as its celestial bodies.
** [[Lighting#Clouds|Clouds]] ({{Class link|Clouds}}) are a global effect representing real-life [[wikipedia:Cloud|cloud]]s.
** The [[Lighting#Atmosphere|atmosphere]] ({{Class link|Atmosphere}}) is a global effect representing real-life [[wikipedia:Atmosphere|atmosphere]].
* [[Graphical user interface|GUI classes]] ([[Class:GuiBase|GuiBase]]) allow the creation and designing of user interfaces. GUI is categorized into two types:
** [[Graphical user interface#2D|2D GUI]] ([[Class:GuiBase2d|GuiBase2d]]): [[Class:ScreenGui|ScreenGui]], which must be parented to [[Class:PlayerGui|PlayerGui]] to work on the client, allows elements to be displayed on the screen, rendering them on top of the 3D scene, while [[Class:SurfaceGui|SurfaceGui]] and [[Class:BillboardGui|BillboardGui]] allow elements to be displayed within the 3D scene.
** [[Graphical user interface#3D|3D GUI]] ({{Class link|GuiBase3d}}): Most 3D elements have properties that link to a 3D-related [[instance]].
* {{Class link|Sound}} allows sound playback linked to an [[audio]] asset.
** [[Class:SoundGroup|SoundGroup]] groups sound together and allows the sounds to be changed through the SoundGroup.
** Sound effects ({{Class link|SoundEffect}}) add effects to a sound.
* Scripts ([[Class:BaseScript|BaseScript]]) are used to make complex systems controlling the behaviour of the place including parts, lighting and GUIs.
** Both {{Class link|Script}}s and {{Class link|LocalScript}}s, or the Script's RunContext property, handle both sides of the [[Script#Client–server model|client-server model]].
** {{Class link|ModuleScript}} allows code to be [[Script#Modularity|modularized]].
** {{Class link|Actor}} allows child scripts to run in [[Script#Parallel programming model|parallel]].

== Designing ==
Designing of a place covers both the place and the art used.

=== Game design ===
Developers may focus on user experience (UX) to make the place more accessible. Roblox supports many devices, however, to utilize a variety of devices, developers may use the [[input]] services provided by Roblox as well as the built-in emulator for devices in Roblox Studio. Roblox has a set of classes used for graphical user interfaces (GUIs) rendered on the Roblox engine, which can be used by developers to customize user interfaces.

=== Art design ===
There are many ways art can be used for both places and [[experience]]s. An experience has an icon and at least one thumbnail. The creator can upload images to change the icon as well as the thumbnail.

Developers can upload their custom meshes, [[Image|images]], [[Material|materials]] and sounds to be used in a place. A place's lighting can be manipulated through the [[Class:Lighting|Lighting]] service.

== Building ==
:{{Main|Building}}

== Scripting ==
Scripting is an activity of writing code designed to be run in a script. One who does this is known as a <em>scripter</em>. Scripters in the development process are responsible for designing systems of the place run by scripts.

On Roblox, scripters are distinguished from programmers in that programmers write code for [[wikipedia:Computer program|computer program]]s in general (such as the engine) rather than scripts, although in the software industry, the terms "scripter" and "programmer" are usually synonymous.

== Community ==
There is a [[Developer Forum]] category ("Help and Feedback") that users may use to reach out to others for assistance in development. The sub-categories cover many processes of the development including designing, scripting and building, as well as how to use Roblox websites or Roblox software.
