What is a JAAP file? A JAAP file is a People Playground contraption. It contains data the game uses to load and show a user-created item, such as a vehicle, building, or weapon. People Playground mods, which are used to add items to the game, often contain JAAP files.

More Information People Playground is a violent sandbox game in which players can mutilate, crush, destroy, and otherwise harm blood-filled ragdolls. To accomplish this, players create weapons, vehicles, structures, and other items, referred to as contraptions. Each contraption is saved as a directory within People Playground's Contraptions directory. A contraption's directory consists of the following files: A JAAP file that describes the contraption's construction and properties A .JSON file that contains contraption metadata An OUTLINE file that describes the contraption's physical outline A .PNG file that serves as the contraption's in-game thumbnail Often, players share contraptions with each other online, on various People Playground-related websites. These shared contraptions are often saved in .ZIP archives. Each of these ZIP archives contains the files listed above, and must be decompressed before it can be used with People Playground. NOTE: JAAP was People Playground's development codename.
