sort of cached table as per duane's underworlds mod. Introduced
shorthand alias mm for multi_map in case not other mods named mm
exist, so that it can be more easily used to reference the API, e.g.
to do vm_data[vi] = mm.node["default:cobble"] instead of having to
fully spell out multi_map
as per paramat's recommendation a temporary "shadow caster" layer
is written above the chunk when underground relative to the current
layer. This works perfectly and lighting works properly while at
the same time it is calculated by the engine. A major change in the
API was however necessary to limit memory usage. The VM, are and
VM data are now initialized in the multi_map core, and passed on
to the generators as otherwise multiple data arrays were created
(one for the shadow caster, one of the generator, one to remove
the shadow caster again) and multiple calls to set_data and
write_to_map... This is also much better in case generators
are chained (i.e. multiple generators being called within a
single mapgen on_generated call)
arguments, updated simple generator to allow switching between different
content ids for the terrain generation, i.e. it can now switch between
stone and sandstone (the one registered is sandstone, the fallback does
not specify arguments during registration so it uses a default, stone).
a fallback (or default if need be) generator in case no layer specified
generator is found. Added sample/ basis mod to demonstrate registration
of map generators. Rewrote Proxima Testauri map generator to conform to
multi_map, simple map generator is fallback in demo. Testauri now uses
a single noise which increases generation time but reduces memory usage.
To try and reduce generation time, it keeps track of the last layer used
and based on that will not reinitialize unless the layer changes.
Fixed typo for the mountain peak seed (said map instead of peak) and the fact the random numbers were generated in the table and then not referenced in the noise parameters (forgot to update when refactoring the code)
Temporarily added a bedrock and skyrock node (in default namespace for now on my local machine as it is in the default mod ... sorry ...). Introduced a layer table containing and a loop to populate the layer settings based on a single random seed and with some noise settings hard coded for now.
