new Debug(game)
A collection of methods for displaying debug information about game objects.
If your game is running in Canvas mode, then you should invoke all of the Debug methods from
your games render
function. This is because they are drawn directly onto the game canvas
itself, so if you call any debug methods outside of render
they are likely to be overwritten
by the game itself.
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!

-
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
