Please note that there's a glitch in Processing 4.0b4 that prevents this from functioning properly. You may need to install version 3.5.4 or the latest version of Processing 4.0 (currently 4.0b8) for this functionality to work. Please make sure to close Processing 4 before opening Processing 3.5.4 (or the current version).

How to build your game (export application)

Each platform is exported to a subfolder. MAKE SURE TO ZIP UP ALL OF THE CONTENTS OF THE EXPORT FOR YOUR GAME TO WORK!! If you just zip the .exe or a random file, it will not function.
