Godot: How to Hard Edit the Binding for UI_Left

In Godot, UI_Left is a predefined action used for navigation. By default, it is bound to the left arrow key and the A key. If you need to change this binding at a deeper level, direct modification is required.

Editing the UI_Left Binding in Godot

To hard edit the binding for UI_Left, follow these steps:

  1. Modify Input Map in Project Settings:
    • Open Project > Project Settings > Input Map.
    • Locate UI_Left and remove existing keys.
    • Assign new keys and save the settings.
  2. Edit the input_map.cfg File:
    • Navigate to your project’s project.godot file.
    • Locate and modify the UI_Left entry under [input].
  3. Use GDScript to Override Bindings:
    • Add the following code in an autoload script:InputMap.action_erase_events("ui_left") InputMap.action_add_event("ui_left", my_new_key)
    • Replace my_new_key with your desired key event.

Ensuring Custom Bindings Work Properly

  • Restart the editor to apply manual changes.
  • Debug using Input.is_action_pressed("ui_left") to confirm the new binding.
  • Use an autoload script to apply changes dynamically across scenes.

With these steps, you can fully customize UI_Left in Godot to suit your project’s needs.
