Phaser.Utils.Debug - 2.6.2

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!

Parameters

Name	Type	Description
`game`	Phaser.Game	A reference to the currently running game.

`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)
