TilingPath's algorithms are designed on the assumption that MultiBrush
segments use unit steps in their point sequences. Non-unit
sequences can result in incorrect or suboptimal tilings.
This change ensures point sequences are validated for unit steps, and
fixes a non-compliant cliff tile across all tilesets.
Adds MultiBrush definitions for River (RA and CnC) and WaterCliff (RA
only), allowing them to be tiled with the Path Tiling tool.
A small enhancement to the MultiBrush and TilingPathTool code is added
to allow the inner type to be derived from start and end types. This
allows segments that interface between types (such as WaterCliff to
Beach) to be usable when tiling either WaterCliffs or Beach. Whilst
this makes the inner types of many of the existing MultiBrushes
redundant, no simplification is performed as part of this change.
Exposes the TilingPath code used by the map generator as a map editor
tool to help automate the process of tiling sequences of templates
together.
No additional template stitching definitions are added as part of this
commit. As such, the tool currently only supports the same auto tiling
as the map generator does. This includes:
- RA and CnC support.
- Beaches, land cliffs, and roads.
Support for additional mods and templates can be added in follow-ups
by adding the necessary MultiBrush definitions.
Related changes included in this commit to support this work include:
- Add support for sparse EditorBlits.
- Add support for MultiBrush to EditorBlitSource conversion.
- Add support for EditorBlitSource previewing.
- Adjust the "Road" types used in segmented MultiBrush definitions.
The editor's resource value calculation logic was fixed in #21820 to
match actual gameplay. The map generator logic originally copied the
editor logic from EditorResourceLayer rather than ResourceLayer and
associated game logic. As such, it inherited incorrect calculations.
This change updates the map generator logic to match the now
consistent logic in both ResourceLayer classes. Map generator resource
settings are also adjusted -25% to continue roughly matching the
previous resource output.
This generalizes TilingPath to accept MultiBrushes instead of templates
and makes the output also a MultiBrush. As a result:
- Composite or faked templates can be used in tiling. This will (in a
later change) be used to support CnC beaches outside of the desert
tileset.
- The tiling result can be previewed without committing it onto the map,
making it more viable for adoption as an editor tool.
- The full shape of the tiling result can be inspected without messily
reading it back off of the map, simplifying some map generator logic.
- Separates map generation-specific segment definitions from the core
template definitions.
- As MultiBrushes can be many-to-one with templates, there is no need to
have a one-to-many template-segment relationship. Multi-segment
templates, such as roads, now use multiple brushes instead. This
simplifies the logic of segment consumers.
Previously, MultiBrushes which contained no offset information in their
definitions were automatically aligned such that the first tile was
under 0,0. This is no longer the case. This was previously done for use
in MultiBrush.PaintArea to improve tile packing success, but the
alignment is now handled automatically by PaintArea instead.
Due to some impure refactoring which changes the randomization of
tiling choices, map generation results may change.
Adds tooltip descriptions for a few map generator settings. The tooltips
are limited to dropdown choices. No tooltips are added for the options
containing the choices or any non-dropdown settings.
- Terrain type
- Bounds shape
- Buildings
The "Square" bounds shape is rephrased as "Rectangle" for consistency
with the added description.
This is UI-only change.
Allows the random map generator to optionally place civilian buildings
around the map for extra decoration. Buildings are placed last with
lowest priority to avoid competing for play area and resources.
Depends on #21738
Spawn generation generally tries to place spawns:
- In spacious areas
- Away from the center (true center or mirror lines)
- Away from a symmetry-projected spawn
- Away from previously placed spawns
This commit introduces the following adjustments:
- The spacing between sequentially placed spawns is relaxed.
- Fix spawn mines contributing too much to the space reservation.
- Factor rotations into anti-center biasing calculation.
- Preserve spacing information in center space fallback decisions.
- Use a linear (instead of binary) falloff for anti-center biasing.
- Enforce that spawns have a minimum buildable area around them.
- Enforce that symmetry-projected spawns have as much separation as
sequentially placed spawns would.
- Allow spawns on or near roads.
Removes all use of floating point from the RaMapGenerator map generator
and its dependencies.
Floating point behavior is potentially non-portable across client
hardware. Removing them should make the map generation logic
consistent even across clients with different floating point hardware
or compiler behavior. This may be useful for sync-safe multiplayer map
generation where clients independently generate the map from settings.
Most previously fractional public-facing settings are now represented
as numbers out of 1000, with some exceptions using 1000000. Most
internal logic which relies on fixed-point concepts now uses 1024ths,
though some floating point mechanisms have been replaced with
alternative discrete approximations (e.g. gaussian to binomial).
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.
