Allows preplaced actors to be rendered on map preview when saving the
map.
Also removes requirements for ResourceLayer in OpenRA.Game and moves it
to OpenRA.Mods.Common.
modify ChooseInitialMap to throw NoAvailalbeMaps exception if no maps were loaded.
implement Utilities.TryWithPrompt - safe execution of a provided action with ability to prompt user on error.
- Add support for escaping '#' inside values
- Add support for escaping leading and trailing whitespace
And when discardCommentsAndWhitespace is set to false:
- Add proper support for comments
- Persist empty lines
Whitespace and comment support requires an explicit opt-in because
they produce MiniYamlNodes with null keys. Supporting these through
the entire game engine would require changing all yaml enumerations
to explicitly check and account for these keys with no benefit.
Comments and whitespace are now treated as real nodes during parsing,
which means that the yaml parser will throw errors if they have
incorrect indentation, even if these nodes will be discarded.
Previously ReleaseBuffer did not immediately null out the buffer, instead the releaseBufferOnCommit flag allows it to be nulled when the texture is next access and the pending changes from the buffer are committed to it. Now the texture is committed immediately, thus the buffer is null once ReleaseBuffer returns.
Once loaded, we force a GC to reclaim temporary memory used during loading. Previously the buffer would not be null as it was pending commit to the texture and thus could not be reclaimed. As soon as we rendered the first frame, the buffer is nulled but we are now in a low GC state - and the buffer will not be reclaimed until the next gen 2 GC which may be dozens of minutes away.
This change ensures the buffer is null in time for the post-load GC, and thus can be reclaimed before we start rendering.
This avoids a crash that stops the maps from being updated
when the base mod ruleset is not valid (e.g. a trait is missing a
FieldLoader.Required property). This also significantly improves the
upgrade performance.
- Rename Bits<T> to BitSet<T>.
- Implement set based helpers for BitSet<T>.
- When representing TargetTypes of ITargetable in various traits, use a BitSet<TargetableType> instead of HashSet<string> for better performance & reduced memory usage.
- Fix FieldLoader to trim input values when generating a BitSet<T>.
- Require T in BitSet<T> and BitSetAllocator<T> to be a class since it's just a marker value. This allows the JIT to instantiate generic code for these classes once, as they don't benefit from specialized code for T. (Typically JITs will generate shared code for all reference types, and unique code for every value type encountered).
We can use MergedStream to create a single combined stream with all the input and pass this to the hash function. This saves copying all the data into a MemoryStream to achieve the same goal, which requires more memory and allocations.
This prevents the capacity being set to 4 when the first item is added. For flat maps, the inverse projection will only ever be of size 1, thus this is sufficient capacity. For isometric maps, 1 is often sufficient, we only need more near height changes where the discontinuity means multiple cells may project back. We can pay for some reallocations to expand the size in these cases.
On flat maps, this reduces the memory required by the backing array 4x.
If the download failed, the map status would be MapStatus.DownloadError,
which would cause the Install method to return immediately. I've updated
the Install method now to account for MapStatus.DownloadError.
