Adding Controller Support

A controller works best when there is an Xbox gamepad mapping for it, that is a description of how to translate the controller’s inputs to Xbox inputs. The game tries to support controllers without mappings, but issues such as ghost button presses have been observed with these controllers.

If you set the buttons in the Controller options and the buttons are represented with numbers, your controller doesn’t have a mapping.

First, try switching the controller to its “Xbox mode” or “Xinput mode” if it has one. If that fails, generate a mapping for your controller:

If you choose to add the mapping to the game’s controller database, you can find the gamecontrollerdb.txt in the game save folder.
