Chunk

A Chunk is a unit defined as either an area of the map 32x32 tiles in size (containing 1024 tiles in total) or a distance of 32 tiles.

Chunks are used for:

• Map generation. When the player runs around and reveals the map or the radar explores the map, it is revealed in chunks.
• Chunks are "switched off" to save CPU cycles. If nothing important happens in a chunk (e.g. there are only fishes swimming around in the chunk) the chunk is not computed in the next Tick.
• The pollution model is based on chunks, and pollution spreads to neighboring chunks.
• The next smaller unit is the Tile.
• The next bigger unit is the Region.
