Description

The objects of Event class contain information about an event that has occurred. Event objects are passed to event listeners when an event occurs.

Usually, event objects contain specific additional information about the event that has occured. For example, when an Event.MOUSE_DOWN event occurs, x and y fields contain the coordinates.

Users can create their own events and dispatch them through the event mechanism.

Examples

Mouse down event example

function onMouseDown(event)
  print(event.x, event.y)
end
mysprite:addEventListener(Event.MOUSE_DOWN, onMouseDown)


User created event

local event = Event.new("myevent")
event.data1 = "12345"
event.data2 = "abcde"
mydispatcher:dispatchEvent(event)

Methods

Event.new creates a new Event object
Event:getTarget returns the element on which the event listener was registered
Event:getType returns the type of Event
Event:stopPropagation stops the propagation of the current event in the scene tree hierarchy
