The Key Up Event.
This event is dispatched by a Key object when it is released.
Listen for this event from the Key object instance directly:
var spaceBar = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.SPACE); spaceBar.on('up', listener)
You can also create a generic 'global' listener. See
Keyboard.Events.ANY_KEY_UP for details.
The Key object that was released.
The native DOM Keyboard Event. You can inspect this to learn more about any modifiers, etc.
