Updates the random map generator to produce more elaborate roads:
- Roads extend beyond map bounds.
- Shorter, unviable roads are pruned and merged to create longer roads.
- Roads can loop.
Coastlines and cliffs at the edge of a map should have been getting
extended beyond the map edge help them tile reliably. This was not
happening due to a conditional that accidentally got inverted during a
refactor.
Fixing the conditional makes beach and cliff tiling significantly more
reliable. (Note that there is no effect on road tiling.)
Add an experimental procedural map generator for the Red Alert mod,
along with supporting code that may assist in the development of map
generators for other mods.
Map generation may be accessed as a tool in the Map Editor. This change
does not presently introduce direct lobby options for generated maps.
Features:
- Terrain with land, water, beaches, cliffs, roads, debris, and trees.
- Placement of mpspawns, neutral buildings, and resources.
- Rotational and mirror symmetry options.
- Various configurable parameters with presets.
- Deterministic with configurable seed.
- Performant.
