Removed property backing fields where applicable, introduced C#7 syntax for properties.
Renamed a bunch of interface properties and class private members with more descriptive names.
Did some inconsequential reordering.
The path cache was originally a moderate benefit, but over time a couple of things have conspired against it:
- Only paths with BlockedByActor.None are cached. Originally all paths regardless of blocking were cached but this was deemed unacceptable due to potentially returning outdated paths as actors move about. Paths with BlockedByActor.None are only invalidated if terrain conditions change, which are rarer.
- Move will try and find a path 4 times, trying with a different BlockedByActor check each time. BlockedByActor.None is the last check and only reached if the other searches fail. This is a rare scenario.
Overall, this means the hit rate for the cache is almost non-existent. Given the constraints on path validity it seems unlikely that the hit rate could be improved significantly, therefore it seems reasonable to remove the cache entirely to remove the overhead of cache management.

Simplified Launch.Map parameter to use map name directly
Firstly, when dealing with maps with height discontinuities, the neighbouring cells we need to search are more that the set we need to search on flat maps. We ensure that as we traverse a map with varying height, we now consider cells "behind" us that may have become accessible due to a height change.
Secondly, when considering connections available via Custom Movement Layers, make sure the target cell on the new layer is actually enterable. Previously this cell would be reported as a valid connection, even if it wasn't actually possible to enter the cell as it was blocked. We also apply the same optimization of ignoring already closed cells.
- 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.
Previously, some paths used a separator and some did not. This broke some de-duplication logic in ExternalMods which tried to enumerate distinct paths but would end up running logic on the same directory more than one as it was provided both with and without a trailing directory separator. By normalizing the path this logic now works.
This also removes a workaround that allowed the current mod to be
registered even if it defined a bogus path. Uses of Game.ExternalMods
should therefore always use TryGetValue and correctly handle it
returning false.
- Extract chat line templates and logic so they can be reused across widgets
- Make text notification styling entirely template driven (by removing chat color configuration and making color optional for `TextNotification`)
- Add a new TextNotificationsDisplay widget (based on and replacing ChatDisplayWidget)
- Add timestamp support to text notifications
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.
