When laying mine with PreLayDelay > 0, end activity's tick immediately. That means don't try to immediately move to next cell.
This change unifies the behavior with scenario when a mine is laid without any PreLayDelay.
Use CollectionsMarshal to hold a ref to the dictionary entry. When the value needs to be added this allows us to set the value directly into it without having to locate the entry a second time.
- Seal the classes, and make SourceLocation a readonly struct.
- In ToDictionary, use TryAdd to avoid a try-catch.
- In Merge, use ToList to ensure sources is only enumerated once.
Moving the key duplication check allows a redundant check on top-level nodes to be avoided. Add tests to ensure key checks are functioning as expected.
- In FieldLoader, cache boxed bools and some boxed ints.
- In FieldLoader, presize collections when parsing a List, HashSet or Dictionary.
- In FieldLoader, don't allocate a list of missing items until required.
- In FieldLoader, when a string value is passed, avoid wrapping this in a MiniYaml object by allowing both strings and yaml to be passed in the GetValue overload that does the real work.
- In Animation, avoid allocating no-op actions.
- In VxlReader, use EnsureCapcity to better size the Dictionary.
- In VxlReader change VxlElement to a struct.
- In Locomotor, presize TerrainSpeeds dictionary.
- In MixFile, the Distinct call doesn't presize the HashSet it uses internally. As we know we will enumerate all results, create the HashSet ourselves so that is it presized correctly.
- In ObjectCreator, stream the assembly when hashing rather than reading all bytes into memory.
These changes avoid some allocations on the large object heap, in turn this means the GC can avoid performing unnecessary Gen 2 collections just to clear down the LOH.
- In RLEZerosCompression use dedicated Array.Clear method instead of open-coded loop.
- In VoxelLoader.GenerateSlicePlanes.Get use TryGetValue to avoid repeated array and dictionary lookups.
- In TmpTSLoader.UnpackTileData use ReadBytes to populate array with less overhead compared to repeated one byte reads.
- Resolve TODO in VqaVideo.
