Structures

[kosinaz]

Structures are built on top of the noise-generated terrain. Mountains, lakes, deserts are all noise-generated, and their small features, the caves, fords, and trees too.

But when tiles with strict rules, like the wall of a house, the roads, or the rivers need to be created, each tile needs to be aware of the nearby tile, and noise is not enough for that.

So a structure layer needs to be created on top of the noise map layer, that will cover the whole map with structure zones, covering a higher number of squares. Each of these will have a single structure strictly inside its borders, like a village, a castle, a dungeon or a temple.

When the player sees the very first tile of a zone, that's when the structure layer of the whole zone will be generated.

The content of each zone is determined by another noise map.
