A G.U.I.D.E to Input in Godot - Part 3: Remapping Controls

Hello Godotneers! In this third part of our G.U.I.D.E. series, we'll explore how we can use G.U.I.D.E. to create a settings dialog for our game where the player can change the key bindings for the game. We'll explore how we can tell G.U.I.D.E which actions should be re-bindable, how we display them in the user interface and how we detect inputs and update the key bindings. We'll also have a look at how we can detect and handle conflicts between key bindings. Finally we're looking into how we can save the key bindings to a file and load them again when the game starts.

We continue with our example project from parts one and two, so if you'd like to follow along, fire up your Godot engine and learn how to remap your controls the easy way!
