Event

You might be looking for one of these pages:

• RBXScriptSignal, the class of events used by ROBLOX Instances.
• Event, an event of the BindableEvent object.

Introduction

An Event is similar to properties - but instead of holding a variable, events "Fire" when a cetain condition is met. Events are found in most objects, and can be used to fire a specific function upon an event occuring, for example:

function partTouched() print("Something has touched the brick!"); end

local part = game.Workspace.Part part.Touched:connect(partTouched)

As seen in the above example, upon a physical object colliding with Part, the text "A brick named <part that collided> has touched the brick!" is printed to the output.

Arguments

Most events have at least one argument, in the next example, we will remove any objects that collide into game.Workspace.Part.

local part = game.Workspace.Part

function collision(hit) hit:Destroy() end

part.Touched:connect(collision)

Being that the Touched event carries one argument, the object that collided into the brick. Lets try another example, this time with the Changed event. In this example, any changes to Part's properties will be printed to the output.

local part = game.Workspace.Part

function somethingChanged(property) print("The " .. property .. " property has been changed!"); end

part.Changed:connect(somethingChanged)

wait(3) part.Name = "Brick"

The above example will print "The Name property has been changed" after about three seconds of the script running.
