Prints the scene to stdout. Used mainly for debugging purposes.
Prints the tree to stdout. Used mainly for debugging purposes. This version displays the path relative to the current node, and is good for copy/pasting into the [method get_node] function. Example output:
[codeblock]
TheGame
TheGame/Menu
TheGame/Menu/Label
TheGame/Menu/Camera2D
TheGame/SplashScreen
TheGame/SplashScreen/Camera2D
[/codeblock]

<description>
Similar to [method print_tree], this prints the tree to stdout. This version displays a more graphical representation similar to what is displayed in the scene inspector. It is useful for inspecting larger trees. Example output:
[codeblock]
┖╴TheGame
┠╴Menu
┃ ┠╴Label
┃ ┖╴Camera2D
┖-SplashScreen
┖╴Camera2D
[/codeblock]
