dat.GUI - A lightweight graphical user interface and controller library

dat.GUI - A lightweight graphical user interface and controller library that allows you to easily manipulate variables and fire functions on the fly, inspired by the venerable dat-gui js.

TLDR;

local DatGUI = require(game.ReplicatedStorage:WaitForChild("dat.GUI"))

local obj = {
  Name = "Alex Rodin",
  Num = 1,
  Winner = true
}

local gui = DatGUI.new()

gui.add(obj, 'Name')
gui.add(obj, 'Num', 1, 50).step(1)
gui.add(obj, 'Winner')

Installation

You can do the installation directly from Roblox Studio, through the Toolbox search for dat.GUI , this is the minified version of the engine (dat.GUI - Roblox).

If you want to work with the original source code (for debugging or working on improvements), access the repository at https://github.com/nidorx/roblox-dat-gui

Roblox dat.GUI

Allows you to easily manipulate variables and fire functions on the fly, inspired by the venerable dat-gui.

dat.GUI magically generates a graphical user interface (sliders, color selector, etc) for each of your variables.

dat.gui’s niche is in listening to and controlling data such that it can be visualized into charts or other graphics. Creating a new DAT.GUI instance provides a new sliding pane for which to add controls to:

Use cases:

1 - To visually debug the various variables in your scripts during development
2 - To create a rich interface for your auxiliary tools (map editors, effects editors, etc.)
3 - For the construction of fast administrative interfaces

How to use

In your script, import the dat.GUI and instantiate it

local DatGUI = require(game.ReplicatedStorage:WaitForChild("dat.GUI"))

-- Create an instance, which also creates a UI pane
local gui = DatGUI.new();

Color3, Color3Value

local color3Value = Instance.new('Color3Value')
local Color3Object = {
   Color3 = Color3.fromRGB(255, 0, 255),
   Color3Value = color3Value
}

gui.add(Color3Object, 'Color3').listen().onChange(function(value)
   assert(Color3Object.Color3.R == value.R)
   assert(Color3Object.Color3.G == value.G)
   assert(Color3Object.Color3.B == value.B)
end)

gui.add(Color3Object, 'Color3Value').listen().onChange(function(value)
   assert(Color3Object.Color3Value.Value.R == value.R)

   OptionsEnum       = 2,
   OptionsEnumItem   = Enum.ScaleType.Slice,
   OptionsArray      = 1,

}

gui.add(OptionsObject, 'OptionsEnum', Enum.ScaleType).listen().onChange(function(value, text)
   assert(OptionsObject.OptionsEnum == value)
end)

gui.add(OptionsObject, 'OptionsEnumItem').listen().onChange(function(value, text)

Lib

Dat.GUI exposes the various components used internally. For usage details see source code

DatGUI.Lib = {
   Panel       = Panel, 
   Popover     = Popover,
   Scrollbar   = Scrollbar,
   GUIUtils    = GUIUtils,
   GuiEvents   = GuiEvents,
   Constants   = Constants
}
DatGUI.Lib.Panel

The basic structure of the GUI. Can be used to create custom dashboards outside of the DAT.GUI framework

  • Panel.new() :Panel
  • panel.attachTo(parent: Frame, isFixed: bool)
    • Add this panel to another element. When doing this, the panel loses some features like scrollbar, resizing and moving
    • isFixed When true, no longer allow unpin this panel
  • panel.detach(closeable: bool)
    • Unpin this panel from the parent element
    • closeable When true, display panel close button, if false, display panel atach button
  • panel.resize(width: number, height: number)
    • Allows you to resize the panel only if it is detached
  • panel.move(hor, vert)
    • Allows the panel to be moved (only when it is not fixed)
    • hor If negative, consider the position from the right edge of the screen
      • {number|"left"|"right"|"center"}
    • vert If negative, consider the position from the bottom edge of the screen
      • {number|"top"|"bottom"|"center"}
  • panel.addAction(config)
    • Add an action button on the right side of the header
    • config.icon Roblox image asset url (Ex. "rbxassetid://7229830060")
      • {string}

      • {string} (optional)
    • config.color
      • {Color3} (optional)
    • config.colorHover
      • {Color3} (optional)
    • config.onHover
      • {function(isHover: bool)} (optional)
    • config.onClick
      • {function()} (optional)
    • @return
      • { {frame:Frame, remove:function()} }
  • panel.onDestroy(callback: function) :RBXScriptConnection
    • Add a callback to be executed when this panel is destroyed
  • panel.destroy()
    • destroy this instance and unbinds all event listeners
  • panel.updateContentSize()
    • Force update of content size information. Informs parents about the content update and triggers the scrollbar update
  • Panel Fields
    • panel.Frame {Frame}
    • panel.Content {Frame}
    • panel.Header {Frame}
    • panel.Closed {BoolValue}
    • panel.Label {StringValue}
DatGUI.Lib.Popover

Popover is a tooltip-like component that allows displaying content above other screen elements. Internally used in ColorController and OptionController. There are 4 popover placement options (“left”|“top”|“bottom”|“right”)

  • Popover.new(reference, size, position, offset)
    • Instantiate a new popover
    • reference GUI object used for popover positioning reference
      • {GUIObject|Frame}
    • size Popover dimensions
      • {Vector2}
    • position Preferred popover position.
      • {"left"|"top"|"bottom"|"right"} (optional default=top)
    • offset Allows you to add a margin between the reference object and the popover
      • {number} (optional default=0)
  • popover.resize(size: Vector2)
  • popover.show(chevron: bool, chevronColor: Color3)
  • popover.hide()
  • popover.destroy()
  • Popover Fields
    • panel.Frame {Frame}
DatGUI.Lib.GuiEvents

Utility methods to facilitate interaction with interface events on elements

  • GuiEvents.onEnter(element :GUIObject|"*", callback :function(isEnter:bool)) :CancelFunction
    • Fired whenever the mouse is over the element (or when it starts a touch event)
  • GuiEvents.onHover(element :GUIObject|"*", callback :function(isHover:bool)) :CancelFunction
    • Fired when the mouse is over the element and this is the element with the highest Z-index
  • GuiEvents.onDown(element :GUIObject|"*", callback :function()) :CancelFunction
    • Fired when the mouse key is pressed over element and this is the element with the highest Z-index
  • GuiEvents.onUp(element :GUIObject|"*", callback :function()) :CancelFunction
    • Fired when the mouse is released over element and this is the element with the highest Z-index
  • GuiEvents.onClick(element :GUIObject|"*", callback :function()) :CancelFunction
    • The click event is sent to an element when the mouse pointer is over the element, and the mouse button
      is pressed and released.
  • GuiEvents.onMove(element :GUIObject|"*", callback :function(position:Vector2)) :CancelFunction
    • Occurs when the mouse is moving over an element
  • GuiEvents.onDrag(element :GUIObject|"*", callback) :CancelFunction
    • Allows dragging elements
    • callback {function(event, startPos:Vector2, position:Vector2, delta:Vector2)}
      • event:"start"|"drag"|"end"
  • GuiEvents.onScroll(element :GUIObject|"*", callback :function(z:number)) :CancelFunction
    • Allows you to watch the mouse scroll over elements

Nice one!
That looks a really good library!
Can you upload a copy to GitHub, so we can send PR’s etc?

I haven’t looked in the source yet but I am wondering did you use roact to create the components, or is it created by instances?

I am seeing how to migrate to a Rojo project (never used it). I tried rojo-rbx but it didn’t generate the GUI templates. If you know how to migrate feel free.

I did not use Roact only Script and ScreenGui, the project started only with a GUI to update the value of a Vector3

I made a pull request to your GitHub repository with your project in Rojo format :smiley:

Hey! A few questions, are you supposed to assign to a frame, gui object of some sort, and if so how.
If not, then does it create a frame, and is there any way to control the position of it inside the script. Other than that I can see myself using this in the near future, really nice plugin keep it up!

I intend to make it more dynamic, allowing it to be used within other elements for example (and from external information such as height and width, internally manage the behavior [scroll, etc.]).

But I confess that it is not my main focus at the moment (I am focused on a game I am developing).

But an important detail, the source code is available on Github, take a look there, very easy to test with Rojo.

This. Is. Amazing. I just made a gui library right now - and oh my god - yours is so much better.
I kinda regret making the library now.

Another thing, why is the module obfuscated? I don’t want some backdoor in my game.

It is minified for ease of use (copying just one file is easier to work with). There is no backdoor, The source code is available on Github, you can generate the minified version itself if you want, or even use it without the minification (you only have to copy more files, as it is modularized).
