How the underground is generated: *todo*.
|
||||
|
||||
Underground is divided into horizontal layers. Bottom of each layer is at
|
||||
fixed height and moved up or down by 2d perlin noise.
|
||||
|
||||
In every layer there can be multiple veins. Veins are blob-shaped volumes
|
||||
of different rocks. Borders of vein are defined by 3d perlin noise. Veins
|
||||
often contain ores.
|
||||
|
||||
In every vein, ores are distributed randomly. Some ores
|
||||
may occur in specific areas of the vein (where noise is higher than
|
||||
treshold) or distributed randomly in specific amount (chance based on
|
||||
pseudorandom number) or combination of both.
|
||||
|
||||
There is 1 2d perlin noise per layer, 1 3d perlin noise per vein and 1
|
||||
pseudorandom number generator per ore.
|
||||
|
||||
Modding Interface
|
||||
-----------------
|
||||
|
||||
"Rocks" exposes api to add new ores, veins and layers. The api is defined
|
||||
in [register](register.lua).
|
||||
|
||||
### Register layer
|
||||
|
||||
rocks.register_layer=function(name,params,rock)
|
||||
|
||||
|
||||
This function registers a layer. Layer is identified by unique string name.
|
||||
Location of layer is specified in params and node, the layer should be
|
||||
composed of is defined by rock.
|
||||
|
||||
Field "params.gain" sets how height of the layer should vary. Field
|
||||
"params.height" sets height of bottom of the layer. Field "params.limit" is
|
||||
value of noise above which the layer is not generated. Set to 2 to disable
|
||||
this feature. Last field "params.seed" is offset to world seed to seed the
|
||||
noise.
|
||||
|
||||
### Register vein
|
||||
|
||||
rocks.register_vein=function(name,params)
|
||||
|
||||
This function registers a vein with name "name" to be generated according
|
||||
to params.
|
||||
|
||||
Field "params.spread" {x,y,z} defines how the vein should look like. X
|
||||
shoudd be equal to z. If y=x=z then the vein is equal in all directions. To
|
||||
make the vein taller, set y to higher value. Larger values make larger and
|
||||
less frequent veins.
|
||||
|
||||
Field "params.treshold" specifies rarity of the vein. It should be betveen
|
||||
-2 and +2, mapgen will use this or per-ore treshold if per-ore treshold is
|
||||
larger.
|
||||
|
||||
- 2 never generate
|
||||
- 1 extremly rare
|
||||
- 0 50% chance
|
||||
- less than 0 = SPAM
|
||||
|
||||
Field "params.seed" is added to world seed to form seed for noise function.
|
||||
|
||||
Depths, where the wein should generate can be controlled by fields hmin and
|
||||
hmax. They can be set to nil to generate everywhere.
|
||||
|
||||
Layers, where the vein should generate in must be listed in Field
|
||||
"params.layer".
|
||||
|
||||
## Register ore
|
||||
|
||||
rocks.register_ore=function( vein, node, params )
|
||||
|
||||
This function registers ore or rock to be generated in vein "vein". Node to
|
||||
be generated is "node". Params specify parameters, where the rock should
|
||||
spawn.
|
||||
|
||||
If noise is larger than Params.treshold, the ore is spawned (set to 2 to
|
||||
spawn everywhere in the vein, 0.8=only in middle). Params.chance specify
|
||||
the chance (/100%) of ore being spawned (0=never 1=always 0.5=50%).
|
||||
|
||||
If multiple ores pass the treshhold and chance tests, ore with highest
|
||||
treshold and smallest chance is spawned.
|
||||
Mod has been rewritten, so no doc yet.
