More nodes

Multiple nodes and naming

You can give a unique name to a node (node === class)

If scene becomes too complex like this

The short path to the target node wild be $Sprite2D/Sprite2D2/Sprite2D3/Target and it's not very readable.

You can add a unique name by right click and chose Access as Unique Name

Now the node have a '%' next to him and you can access it by %Target much more readable.

Access parents information from children

$".." représent the parent node

If a function test_function() is in the parent node, you can access it from the child node by using $"..".test_function()

Major aspect of Godot, each nodes communicate with each other. We can make nodes work together in the same scene. Later we can also work across multiple scenes.
