📖 API documentation: docs.doodesch.de/mods/mapexpansions/api/

> Framework and API for mods that add map areas and property upgrades. Another mod brings the content, MapExpansions builds it into the world.

For players

Install it when a mod asks for it, like Based. On its own it adds nothing you can see.

In co-op, every player needs it and the same version of the mods that use it.

For mod authors

Register an ExpansionDefinition in OnInitializeMelon:

• New areas: terrain from a source scene, connections to the main world, regions and a sheet on the phone map.
• Life in the area: NPC and vehicle navigation, buildings, parking lots, deal locations, shops and a police station.
• Properties: copy a property to a new place, or extend an existing one with new floor, grids and docks.
• World states: named states you switch at runtime and take back, for upgrades that build up over time.
• Edits: hide, cut or copy main-world objects, in code or from a JSON layer.

Declare the dependency with [assembly: MelonAdditionalDependencies("MapExpansions")] and add DooDesch-MapExpansions-1.0.0 to your manifest.json. Reference the DLL, do not copy the code.

Requirements

• MelonLoader 0.7.3 or newer

If you have fun with it, a like on the Thunderstore page really helps other people find it (thumbs up next to Download, you need to be logged in) - ty either way, and lemme know if anything breaks or you've got ideas
