Configuring Overgrowth

From Wolfire Games Wiki
Jump to: navigation, search

You can edit most settings by pressing the Settings button on the main menu or on the pause menu. If the game does not open, or it is not possible to access the settings from inside the game, you can change your configuration by modifying the config.txt file.

Note: There is now a community made tool available, the SUMLauncher, which includes a config editor.

Alternatively you can find out how to unhide your Library folder permanently here.

Controller Setup

Since alpha 150, external controller options have been added to the config.txt file. The following guide will help you configure your controller to properly work with Overgrowth.

Note: Currently the guide only targets Windows 7 users. Mac users may refer to Anton's guide.

First, make sure your controller is plugged in to your computer.

Next, open the start menu and click on Control Panel (located on the right side). Once opened, make sure the view is set to Large Icons (switchable in the upper right corner). Select Devices and Printers.

You should see your controller listed under Devices. Right click it, and select Game Controller Settings. The Game Controllers window will appear. Make sure your controller is selected, then click on Properties.

Once again, a new window should appear - make sure that the view is set to the Test tab. In this view, you will be able to determine which physical button is mapped to each virtual button. Play around with your controller to confirm that everything is working properly, and take note of the button mappings.

Now navigate to and open up your config.txt file (as described above). Rearrange the mappings in the file to match your desired controller setup.

Once you have everything modified, save the config.txt file and launch Overgrowth in order to test the new configuration.
