The TraitsImplementing<T> performs a dictionary lookup to match up its generic type parameter with the right trait collection. Since actors are rendered so much, it is useful to cache this result to avoid looking it up repeatedly.
Targeted some methods that generated allocated a lot of memory in the main game loop:
- Actor.Render - Changed LINQ calls into equivalent loops. No allocation for delegates.
- Animation.Render - Returned an array rather than a yield expression. The array uses less memory than the complier generated enumerable.
- FrozenActor and FrozenUnderFog - Materialize the footprint into an array: The enumerable is not-trivial to evaluate is and evaluated many times inside the Tick function. The memory needed is minimal. Changed LINQ into equivalent loops to prevent delegate allocation. Should result in overall much faster calls.
- Widget.GetEventBounds - Changed LINQ calls into equivalent loops.
- MobileInfo.CanEnterCell - Changed LINQ calls into equivalent loops. Don't materialize list of blocking actors every time, instead enumerate them and only when they need to be checked.
- FrozenUnderFog.TickRender - Generate the renderables lazily and also remove a no-op Select call.
Actor, CPos, CVec, WAngle, WPos, WRange, WRot and WVec structs now implement IEquatable<T> which means unboxing/casting costs can be eliminated.
Also simplified the ToString method by concatenating components directly rather than using a format string since the overhead is a bit high for simple cases like this.
- Each player has their own shroud and their visibility does not extend outside of the shroud.
- Units and buildings can no longer target other units outside of their visibility. Buildings can still be targetted if they have been explored.
- GPS will provide visibility in the fog-of-war.
- Spies that infiltrate radar domes will gain their victim's exploration and reset it on all clients (if the victim does not have GPS)
