Blueprint

Blueprint is an XML format used to store the job lots (nightclub, restaurant, and robot factory) and default house offline in The Sims Online. These are probably not used client-side because "blueprints" and "default_house" do not appear in the game EXE or any of its DLL.

Background

A modified version of the Blueprint format during FreeSO's alpha stage. During this phase, Rhys created a blank lot that could be loaded into the game. This version was capable of being written and streamed to in real time, allowing for players to build and share their lots, similar to the mainline games. Today, it serves as a sandbox mode for further development of new objects and features.

My Simulation uses a JSON variant for better readability and to make use of existing APIs in Zig's standard library. While the project intends to use it for a similar purpose as FreeSO did during its development, Tony Bark plans to expand this feature into a fully playable P2P mode for smaller scale communities.
