Intro
This article introduces how world generation is handled in Vintage story, and the extent to which it can be modded. It is also intended as a general introduction for modding endeavors in regards to world generation.
Terminology
Important terminology to note while reading this article:
- Chunk (An area of 32x32x32 blocks. It is of note that chunks do not span the world height.)
- Chunk column (A set of chunks spanning the vertical height of the world. Given a world height of 256, a chunk column would represent 8 vertically stacked chunks)
- Map chunk (The area covered by a chunk column, but not referring to the chunks therein)
- Region (The area covered by 16x16 chunk columns)
Concept
World generation is the process of generating necessary data about the world when the player requires it. World generation is done on a region, map chunk and chunk column basis - each acting as a meaningful subdivision of the world. Each region, map chunk and chunk column is only generated once and stores important data about that area. World generation is very modular. Almost all generated parts of the world, such as ore deposits, creatures or trees, are specified via JSON content mods. On a coding level, each stage of generation triggers an event which the base game registers handlers to. Event handlers can be registered or removed through the API to alter any part of generation.
Content modding
Using content modding, here are the various things that can be added, modified or removed from world generation. Properties relative to world generation are generally located at Vintagestory/assets/survival/worldgen
Moddable content
