This allows actor.Info.HasTraitInfo to be used when checking if an actor needs to be added to the index, which is a cheaper call than actor.TraitsImplementing.
The AI would often invoke this method inside of loops, searching for a different category of queue each time. This would result in multiple searches against the trait dictionary to locate matching queues. Now we alter the method to create a lookup of all the queues keyed by category. This allows a single trait search to be performed.
UnitBuilderBotModule and BaseBuilderBotModule are updated to fetch this lookup once when required, and pass the results along to avoid calling the method more times than necessary. This improves their performance.
Several parts of bot module logic, often through the AIUtils helper class, will query or count over all actors in the world. This is not a fast operation and the AI tends to repeat it often.
Introduce some ActorIndex classes that can maintain an index of actors in the world that match a query based on a mix of actor name, owner or trait. These indexes introduce some overhead to maintain, but allow the queries or counts that bot modules needs to perform to be greatly sped up, as the index means there is a much smaller starting set of actors to consider. This is beneficial to the bot logic as the TraitDictionary index maintained by the world works only in terms of traits and doesn't allow the bot logic to perform a sufficiently selective lookup. This is because the bot logic is usually defined in terms of actor names rather than traits.
Previously, the ClosestTo and PositionClosestTo existed to perform a simple distance based check to choose the closest location from a choice of locations to a single other location. For some functions this is sufficient, but for many functions we want to then move between the locations. If the location selected is in fact unreachable (e.g. on another island) then we would not want to consider it.
We now introduce ClosestToIgnoringPath for checks where we don't care about a path existing, e.g. weapons hitting nearby targets. When we do care about paths, we introduce ClosestToWithPathFrom and ClosestToWithPathTo which will check that a path exists. The PathFrom check will make sure one of the actors from the list can make it to the single target location. The PathTo check will make sure the single actor can make it to one of the target locations. This difference allows us to specify which actor will be doing the moving. This is important as a path might exists for one actor, but not another. Consider two islands with a hovercraft on one and a tank on the other. The hovercraft can path to the tank, but the tank cannot path to the hovercraft.
We also introduce WithPathFrom and WithPathTo. These will perform filtering by checking for valid paths, but won't select the closest location.
By employing the new methods that filter for paths, we fix various behaviour that would cause actors to get confused. Imagine an islands map, by checking for paths we ensure logic will locate reachable locations on the island, rather than considering a location on a nearby island that is physically closer but unreachable. This fixes AI squad automation, and other automated behaviours such as rearming.
