Ensure the target location can be pathed to by all units in the squad, so the squad won't get stuck if some units can't make it. Improve the choice of leader for the squad. We attempt to a choose a leader whose locomotor is the most restrictive in terms of passable terrain. This maximises the chance that the squad will be able to follow the leader along the path to the target. We also keep this choice of leader as the squad advances, this avoids the squad constantly switching leaders and regrouping backwards in some cases.
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.
I noticed even on a naval only map, the naval AI doesn't necessarily beat a Normal AI. This makes it much more likely that it will.
- Drop number of ore refineries and ore trucks. As Naval AI is mostly suited for islands I haven't found a map that really needs as many as the other AIs.
- Reduce number of ground based base defenses - and delay Tesla coil a lot.
- Reduce number of migs as yaks more useful if they just get blown up.
- Add Flak trucks and v2s for base defense for Soviet
- Add Jeep and Arty for base defense for Allied
- Add delay for building ore truck so now chance of building one first from War Factory
- A service depot is not useful for this AI except for building an MCV so delay it a lot.
Tested with Ukraine and Germany and can consistently beat normal on island map.
1. Only allow new item being queued when cash above a certain number
2. Only tick one kind of queues at one tick, reduce the pressure on the actived tick
3. 'BaseBuilderBotModule' will check all buildings in producing, avoid queue mutiple same buildings.
If nested calls to RunUnsynced are running, then using a bool would cause the flag to be reset once the inner function completes, but an outer function may still be running and not yet ready for the flag to be reset. To correctly handle nested calls, we track a count and only reset the flag once all functions have completed.
As the solution currently targets .NET 6, a variety of style rules only introduced in .NET 7 are not suitable for enforcing as warnings (which are treated as errors in the CI pipeline). Anybody compiling locally with a .NET 6 SDK won't be able to trigger these rules locally, but the Linux CI agent comes with the .NET 7 SDK and will trigger these rules. This provides a poor dev experience as the CI run will report errors that don't reproduce locally.
To remove this developer friction, reduce the severity of these rules to avoid CI runs failing.
