Godot Controls Remap

ControlsRemap will store your input mapping. It's a resource, so you can save it and load it. It supports keyboard and joypad separately. You can use it to have easily customizable controls in your game.

How does it work?

First enable the Controls Remap addon and define what actions you want to handle in addons/ControlsRemap/action_list project setting. To create a remap, the resource will go over these actions and look for InputEventKey and InputEventJoypadButton. It will store the keycode/button_index of the first events it finds in the action. When the ControlsRemap is first created, it will use the currently assigned buttons as defaults, so it's important to create it before any input is edited.

The remap is applied by looking for InputEvents inside action and replacing its button id. It might sound complicated, but it's done automatically by using methods. The class includes a built-in documentation.

Usage

First, you need to create the remap resource:

var remap = ControlsRemap.new()

Be sure to customize your actions first.

Then you can edit the assigned buttons by using set_action_key() for keyboard or set_action_button() for joypad. For example, you can listen for input and do:

func _input(event):
    if event is InputEventKey:
        remap.set_action_key(current_action, event)

After this operation, Input.is_action_pressed(current_action) will use the key you just changed.

After you customized your controls, use remap.create_remap() to store your assigned buttons inside ControlsRemap resource. Then you can use ResourceSaver.save("user://my_remap.tres", remap) to save your remap to a file.

After that, instead of creating a new ControlsRemap resource, you can do:

var remap = load("user://my_remap.tres")
remap.apply_remap()

to apply your stored controls.

To sum up:

create a ControlsRemap resource
use set_action_key() or set_action_button() methods to customize your InputMap
use create_remap() to store your InputMap keys/buttons in the remap resource
use ResourceSaver to save it to a file and ResourceLoader to load it later
after loading, you can replace your InputMap by using apply_remap()

The remap works well with my Action Icon asset, because it allows to easily display the assigned keys. If you want to display the controls yourself, you can use get_action_key() and get_action_button() to get relevant input events.

Notes

The remap stores both keyboard and joypad actions, so you can use it in your game to easily configure keyboard and joypad controls. Although your input action needs both keyboard and joypad assigned. For example:

If an action has no keyboard or joypad buttons assigned, trying to set or store them will have no effect.

The remap created with create_remap() will only store actions that are different from the defaults.

Other stuff

Aside from that, the ControlsRemap has a few other useful things.

prefix can be used for multiplayer controls. E.g. if you have p1_ prefix, the ControlsRemap will use p1_jump instead of jump action. This way you can have easily customizable multiplayer controls. Use multiple ControlsRemap files to store controls for many players.

Use restore_default_controls() to restore everything to default or restore_action_default() to restore one action to its default inputs.

You can use clone_remap() to temporarily store curreent input. For example, if you have some customized actions, but want to restore them later, you can use clone_remap() before going to control settings menu and then restore_cloned_remap() to restore the previous controls if the user cancels the settings.

Lastly, there is find_duplicates() method that returns conflicting actions, i.e. action names of actions that have the same key/button assigned.
