By maintaining a set of changed cells we can avoid repeating work for cells that change multiple times before being rendered. The shroud renderer and radar widget now delay their work until they must render, and thus process each changed cell only once. This avoids significant repetition that was causing major slowdown when many actors were in the world.
The FrozenUnderFog.Tick method will now reuse the calculation do by the frozen actor when it had to calculate its visibility, this prevents it having to re-do the fairly expensive visibility calculation.
Introduced also a small Unit test project to prove it.
- Separated caching capabilities from PathFinder class to increase cohesion and maintainability.
Refactored the pathfinding algorithm by extracting methods based on responsibilities like
calculating costs and reordering functions. These changes should provide a in average a small increase in
pathfinding performance and maintainability.
- Optimized the pathfinder algorithm to reuse calculations like the
MovementCost and heuristics.
- Introduced base classes, IPathSearch and IPriorityQueue interfaces,
and restructured code to ease readability and testability
- Renamed the PathFinder related classes to more appropriate names. Made the
traits rely on the interface IPathfinder instead of concrete PathFinder
implementation.
- Massive performance improvements
- Solved error with harvesters' Heuristic
- Updated the heuristic to ease redability and adjustability. D can be
adjusted to offer best paths by decreasing and more performance by
increasing it
- Refactored the CellLayer<CellInfo> creation in its own Singleton class
- Extracted the graph abstraction onto an IGraph interface, making the
Pathfinder agnostic to the definition of world and terrain. This
abstraction can help in the future to be able to cache graphs for similar
classes and their costs, speeding up the pathfinder and being able to feed
the A* algorithm with different types of graphs like Hierarchical graphs
A unit with the CreatesShroud or RevealsShroud trait must update all shrouds when it changes position. Calculating the tiles it can currently see is an expensive calculation that previously had to be repeated for every shroud that needed to know these tiles.
Now, we lazily populate a ref parameter to allow it to be reused for an actor if possible. The biggest improvement comes from the fact that allied players can re-use this calculation when updating their shrouds. Since many games includes a neutral player allied to both sides, most games will see a decent speedup.
