Plans API for Minecraft 1.8


Plans API provides modders which are very flexible API to include in their own mods that allows them to customize the generation of instant structures.

Plans API uses a rules-based engine to generate Minecraft structures. A JSON file (*.plan.json), called a Plan contains all the properties and rules used to construct a particular structure. The Plan file can be very simple and straight-forward to a very complex set of Plans that substitutes blocks, and adds support rules, connectors, conditions, spawners and chests.


  • Rules-based generation
  • Easy to read and modify JSON files
  • Caching System for quicker access and rendering
  • In-memory Database for Plan grouping and categorizations. There is no more need for complex directories to organize files.
  • Build Sets and Group Plans are together to form larger structures. Swap components or use the same component multiple times.
  • Structural Support Rules. Blocks can be set to either provide support or require support or both. If the block doesn’t receive enough support, it is not built. It is great for creating ruins and/or dungeons.
  • Conditional Rules and Block construction if based on conditions of existing world blocks. For example, if world block is water, you can build by stone brick and else don’t build block at all.
