Gameplay

The Powder Toy, (commonly abbreviated as TPT), is a sandbox video game programmed primarily in C++ that allows users to create content in-game to share using its online level sharing system, although posting such content is optional. The game offers a wide variety of element types and tools for it’s players to use, such as electricity-related elements, radioactive elements, explosives, liquids, powders and various other ‘tools’ that can affect the properties of other elements.[8]

A public server for sharing in-game creations is provided as part of the game itself, allowing users to share anything that abides by the rules. Examples of player shared creations include functioning circulatory systems, nuclear power plants, nuclear bombs, and computers.[5] Content is rated using upvotes and downvotes, and can be reported to the moderators if it breaks on-site/in-game rules.

Modding

The Powder Toy allows users to add plugins and mods to the game with Lua scripting[9] and edit the mainly C++ code base. The source code is available on GitHub and can be compiled using Meson.[10]

A mod manager can be installed using the built-in console using the tpt.installScriptManager()[11] command.

Users have created many forks and mods for the game.[12]
