Factories

A factory in software refers to a class that creates objects. This design pattern is used over just calling the constructor to do additional processing ot initialize other components.

ButtonFactory

The ButtonFactory is used to create buttons with default values. This is done so the same values don't need to be entered each time an object is created. The ButtonFactory works as an object, so it does need to be created. When it is created, ButtonFactory:SetDefault(PropertyName,Property) and ButtonFactory:UnsetDefault(PropertyName) can be used to set and unset the default properties. ButtonFactory:Create() is then used to create buttons.

--Create a button factory.
local ButtonFactory = require(game.ReplicatedStorage:WaitForChild("NexusButton"):WaitForChild("Factory"):WaitForChild("ButtonFactory"))
local Factory = ButtonFactory.new()

--Set the defaults.
Factory:SetDefault("Name","CustomName")
Factory:SetDefault("BackgroundColor3",Color3.new(1,1,1))
Factory:SetDefault("BorderSizeScale",0.1)

--Create a button.
local Button = Factory:Create()
print(Button.Name) --CustomName
print(Button.BackgroundColor3) --1, 1, 1
print(Button.BorderSizeScale) --0.1

--Unset a default.
Factory:UnsetDefault("BorderSizeScale")

--Create a button.
local Button = Factory:Create()
print(Button.Name) --CustomName
print(Button.BackgroundColor3) --1, 1, 1
print(Button.BorderSizeScale) --0.2

To use the style used in other projects, a default factory can be used which takes the base color as a parameter.

--Create a button factory.
local ButtonFactory = require(game.ReplicatedStorage:WaitForChild("NexusButton"):WaitForChild("Factory"):WaitForChild("ButtonFactory"))
local Factory = ButtonFactory.CreateDefault(Color3.new(0,170/255,255/255))

--Create a button.
local Button = Factory:Create()
print(Button.BackgroundColor3) --0, 0.666667, 1
print(Button.BorderColor3) --0, 0.54902, 0.882353
print(Button.BorderTransparency) --0.25

TextButtonFactory

Nexus Button differs from Nexus Button Class (previous concept) where text isn't integrated into the button. To get around this, a TextButtonFactory can be used. TThe create method is a bit difference since it returns the button and the TextLabel in the button. TextLabel defaults can be set and unset with ButtonFactory:SetTextDefault(PropertyName,Property) and ButtonFactory:UnsetTextDefault(PropertyName).

--Create a button factory.
local TextButtonFactory = require(game.ReplicatedStorage:WaitForChild("NexusButton"):WaitForChild("Factory"):WaitForChild("TextButtonFactory"))
local Factory = TextButtonFactory.CreateDefault(Color3.new(0,170/255,255/255))

--Set the defaults.
Factory:SetDefault("Name","CustomName")
Factory:SetDefault("BackgroundColor3",Color3.new(1,1,1))
Factory:SetDefault("BorderSizeScale",0.1)
Factory:SetTextDefault("Font","SciFi")
Factory:SetTextDefault("Text","Button")

--Create a button.
local Button,TextLabel = Factory:Create()
print(Button.Name) --CustomName
print(Button.BackgroundColor3) --1, 1, 1
print(Button.BorderSizeScale) --0.1
print(TextLabel.Font) --Enum.Font.SciFi
print(TextLabel.Text) --Button

--Unset a default.
Factory:UnsetDefault("BorderSizeScale")
Factory:UnsetTextDefault("Text")

--Create a button.
local Button,TextLabel = Factory:Create()
print(Button.Name) --CustomName
print(Button.BackgroundColor3) --1, 1, 1
print(Button.BorderSizeScale) --0.2
print(TextLabel.Font) --Enum.Font.SciFi
print(TextLabel.Text) --Label

Like the ButtonFactory, there is a default factory used by other projects.

--Create a button factory.
local TextButtonFactory = require(game.ReplicatedStorage:WaitForChild("NexusButton"):WaitForChild("Factory"):WaitForChild("TextButtonFactory"))
local Factory = TextButtonFactory.CreateDefault(Color3.new(0,170/255,255/255))

--Create a button.
local Button,TextLabel = Factory:Create()
TextLabel.Text = "Button"
