Pre-parsed scene tree path.
</brief_description>
<description>
A pre-parsed relative or absolute path in a scene tree, for use with [method Node.get_node] and similar functions. It can reference a node, a resource within a node, or a property of a node or resource. For instance, [code]"Path2D/PathFollow2D/Sprite:texture:size"[/code] would refer to the size property of the texture resource on the node named "Sprite" which is a child of the other named nodes in the path. Note that if you want to get a resource, you must end the path with a colon, otherwise the last element will be used as a property name.
You will usually just pass a string to [method Node.get_node] and it will be automatically converted, but you may occasionally want to parse a path ahead of time with [code]NodePath[/code] or the literal syntax [code]@"path"[/code]. Exporting a [code]NodePath[/code] variable will give you a node selection widget in the properties panel of the editor, which can often be useful.
A [code]NodePath[/code] is made up of a list of node names, a list of "subnode" (resource) names, and the name of a property in the final node or resource.

<description>
Create a NodePath from a string, e.g. "Path2D/PathFollow2D/Sprite:texture:size". A path is absolute if it starts with a slash. Absolute paths are only valid in the global scene tree, not within individual scenes. In a relative path, [code]"."[/code] and [code]".."[/code] indicate the current node and its parent.
