addKey(keycode) → {Phaser.Key}

If you need more fine-grained control over a Key you can create a new Phaser.Key object via this method. The Key object can then be polled, have events attached to it, etc.

Parameters:

Name	Type	Description
keycode	number	The keycode of the key, i.e. Phaser.Keyboard.UP or Phaser.Keyboard.SPACE_BAR

Source:

• input/Keyboard.js, line 98

Returns:

The Key object which you can store locally and reference directly.

Type

Phaser.Key

addKeyCapture(keycode)

By default when a key is pressed Phaser will not stop the event from propagating up to the browser. There are some keys this can be annoying for, like the arrow keys or space bar, which make the browser window scroll. You can use addKeyCapture to consume the keyboard event for specific keys so it doesn't bubble up to the the browser. Pass in either a single keycode or an array/hash of keycodes.

Parameters:

Name	Type	Description
keycode	Any

Source:

• input/Keyboard.js, line 180

clearCaptures()

Returns:

An object containing properties: up, down, left and right. Which can be polled like any other Phaser.Key object.

Parameters:
