Scene Unique Nodes
==================
Introduction
------------
There are times in a project where a node needs to be called
from a script. However, its position in the tree might change
over time as adjustments are made to a scene, such as a
button in a UI scene.
In situations like this, a node can be turned into a scene
unique node to avoid having to update a script every time
its path is changed.
Creating and using them
-----------------------
In the Scene tree dock, right-click on a node and select
**Access as Scene Unique Name** in the context menu.
.. image:: img/unique_name.png
After checking this, the node will now have a percent symbol (**%**) next
to its name in the scene tree:
.. image:: img/percent.png
To use a unique node in a script, use the ``%`` symbol and the node's
name in the path for ``get_node()``. For example:
.. tabs::
.. code-tab:: gdscript GDScript
get_node("%RedButton").text = "Hello"
