bindable

Bindable is an extremely lightweight & fast implementation of RBXScriptSignal.

Why Bindable?

• Almost fully replicates RBXScriptSignal's behavior
• Lightweight & fast
• Open-source
• 4X faster than Roblox's BindableEvent

Usage

Connection Example:

local Bindable = require(game.Path.To.Bindable)
local HelloPlayer = Bindable.new()

HelloPlayer:Connect(function(Player)
    print("Hello, " .. Player.Name .. "!")
end)

game.Players.PlayerAdded:Connect(function(Player)
    HelloPlayer:Fire(Player) -- Hello, Username!
end)

Multi-Connections Example:

local Bindable = require(game.Path.To.Bindable)
local HelloPlayer = Bindable.new()

HelloPlayer:Connect(function(Player)
    print("Hello, " .. Player.Name .. "!")
end)

HelloPlayer:Connect(function(Player)
    print("Hello, " .. Player.DisplayName.. "!")
end)

game.Players.PlayerAdded:Connect(function(Player)
    HelloPlayer:Fire(Player) -- Hello, Username!, Hello, DisplayName!
end)

Once Example:

local Bindable = require(game.Path.To.Bindable)
local HelloPlayer = Bindable.new()

HelloPlayer:Once(function(Player)
    print("Hello, " .. Player.Name .. "!")
end)

game.Players.PlayerAdded:Connect(function(Player)
    HelloPlayer:Fire(Player) -- Hello, Username!
    task.wait(2)
    HelloPlayer:Fire(Player) -- Nothing
end)

Wrap Example:

local Bindable = require(game.Path.To.Bindable)
local Part = workspace.Part
local onNameChanged = Bindable.Wrap(Part:GetPropertyChangedSignal("Name"))

onNameChanged:Connect(function()
    print("Name of Part was changed to: " .. Part.Name)
end)

Part.Name = "Bindable"
