new Debug(game)
A collection of methods for displaying debug information about game objects. If your game is running in WebGL then Debug will create a Sprite that is placed at the top of the Stage display list and bind a canvas texture to it, which must be uploaded every frame. Be advised: this is very expensive, especially in browsers like Firefox. So please only enable Debug in WebGL mode if you really need it (or your desktop can cope with it well) and disable it for production! If your game is using a Canvas renderer then the debug information is literally drawn on the top of the active game canvas and no Sprite is used.
Parameters:

Render a Sprites Physics body if it has one set. The body is rendered as a filled or stroked rectangle. This only works for Arcade Physics, Ninja Physics (AABB and Circle only) and Box2D Physics bodies. To display a P2 Physics body you should enable debug mode on the body when creating it.
Parameters:
Name Type Argument Default Description sprite
Phaser.Sprite The Sprite who's body will be rendered.
color
string <optional>
'rgba(0,255,0,0.4)' Color of the debug rectangle to be rendered. The format is a CSS color string such as '#ff0000' or 'rgba(255,0,0,0.5)'.
filled
boolean <optional>
true Render the body as a filled rectangle (true) or a stroked rectangle (false)
- Source - utils/Debug.js, line 742
