An event is added to Map to indicate when the cell projection is changed. This is important as this can mean Map.Contains(CPos) could now return different results for the cell. The HierarchicalPathFinder is made aware of these changes so it can rebuild any out-of-date information. This fixes prevent a crash if a cell that was previously outside the map changes height and becomes inside the map. The local path search will explore the cell as it is inside the map - but if the HPF was unaware if had been updated, it will still consider the cell to be outside the map and unreachable, resulting in a crash.
Replaces the existing bi-directional search between points used by the pathfinder with a guided hierarchical search. The old search was a standard A* search with a heuristic of advancing in straight line towards the target. This heuristic performs well if a mostly direct path to the target exists, it performs poorly it the path has to navigate around blockages in the terrain. The hierarchical path finder maintains a simplified, abstract graph. When a path search is performed it uses this abstract graph to inform the heuristic. Instead of moving blindly towards the target, it will instead steer around major obstacles, almost as if it had been provided a map which ensures it can move in roughly the right direction. This allows it to explore less of the area overall, improving performance.
When a path needs to steer around terrain on the map, the hierarchical path finder is able to greatly improve on the previous performance. When a path is able to proceed in a straight line, no performance benefit will be seen. If the path needs to steer around actors on the map instead of terrain (e.g. trees, buildings, units) then the same poor pathfinding performance as before will be observed.
This helps improve the safety of code the uses reflection when methods may get renamed, and helps navigating code as the nameof will show up when searching for references to members.
Aligns the naming conventions defined in editorconfig (dotnet_naming_style, dotnet_naming_symbols, dotnet_naming_rule) which are reported under the IDE1006 rule with the existing StyleCop rules from the SA13XX range.
This ensures the two rulesets agree when rejecting and accepting naming conventions within the IDE, with a few edges cases where only one ruleset can enforce the convention. IDE1006 allows use to specify a naming convention for type parameters, const locals and protected readonly fields which SA13XX cannot enforce. Some StyleCop SA13XX rules such as SA1309 'Field names should not begin with underscore' are not possible to enforce with the naming rules of IDE1006.
Therefore we enable the IDE1006 as a build time warning to enforce conventions and extend them. We disable SA13XX rules that can now be covered by IDE1006 to avoid double-reporting but leave the remaining SA13XX rules that cover additional cases enabled.
We also re-enable the SA1311 rule convention but enforce it via IDE1006, requiring some violations to be fixed or duplication of existing suppressions. Most violations fixes are trivial renames with the following exception. In ActorInitializer.cs, we prefer to make the fields private instead. ValueActorInit provides a publicly accessible property for access and OwnerInit provides a publicly accessible method. Health.cs is adjusted to access the property base instead when overriding. The reflection calls must be adjusted to target the base class specifically, as searching for a private field from the derived class will fail to locate it on the base class.
Unused suppressions were removed.
- Stream lines in as memory rather than needing to realise a string for each line, via a new method in StreamExts.
- Use span to avoid string allocations during parsing until we want to realise the node itself, in MiniYaml.FromLines.
- Change several callsites to use the streaming extension method rather than string method where possible.
In CellInfoLayerPool, instead of having to store a layer with the default values, we know we can just clear the pooled layer in order to reset it. This saves on memory, and also makes resetting marginally faster.
In PathSearch, we need to amend a check to ensure a cell info is not Unvisited before we check on its cost.
We observe that most cells within a map lie within a region where no matter their height, their projection would still remain in map bounds. We can utilise this to perform a fast check for such cells and skipping the expensive checks on their actual height. We only need to check the actual height of a cell if this could cause the projection to go out of bounds.
* TSVeinsRenderer now shows border cells on the radar
* BuildableTerrainLayer now uses the radar colors defined on the individual tiles
* CliffBackImpassabilityLayer no longer overrides the underlying terrain color.
