Thanks! * Went over speed groups with a fine-toothed comb in terms of their fast-blast sync in multiplayer, and it all looks good. Put in slight extra instrumentation to let us know if there is actually an oversight, but at the moment it looks like the error is really on the side of fast-blast shots, not speed groups, and the speed groups were a downstream casualty. * Updated the central dictionaries that have lookups for shots, ships, and wormholes to be concurrent dictionaries that expect access from 8 threads at once (but can do more). This mostly affects nothing, but in certain cases where we were trying to write to one of those dictionaries from two threads at once, it will prevent any issues. ** What we were observing in some cases (one client out of five in a six player game, for example) is that shots were failing the basic method call of "assign self into dictionary by ID." This should be frankly impossible, but it was erroring on an internal method call TryInsert on the Dictionary<> class. That's a great sign that there is a cross-threading issue going on, because again that should be impossible in any other circumstance. So the simple solution is switching to a ConcurrentDictionary<>, and that problem should go away. |
