Many games require complex sets of data to be run. For instance dialog and cutscene systems that allow for several choices or randomly select a piece of text to be displayed can be extremely complicated and hard to make via godot's native in built systems. It is also possible to write the data in a file by hand, but this can easily lead to one making mistakes which can be hard to spot.
To make your own life easier, it is advisable to build your own tools, with which you can quickly create and edit said data with less risk of introducing bugs.
To better help you with this step, I created this tutorial, which will show you how you can make your own item editor inside the Godot Editor. Further this tutorial demonstrates a use case of said data by providing a simple item inventory scene.
Be warned that this is not a tutorial for beginners. If you have no knowledge of coding, or are are still struggling with it, this tutorial is likely not for you.
