Jeffy (and woosel) used to have 100% hitchance v each other, now they keep missing and firing at where the other used to be. What happened and can it be fixed?

I don't think it ever was 100%, they did miss in the past too albeit very rarely. But yeah it's gotten worse, they even shoot other allied jeffies from time to time.

I guess it could be related to the pathing changes in the engine and/or the turninplace change in BA, making the jeffies change their path more radically on the moment when the unit fires, and they evade it even when it's near-instananeous hit.

Gotta micro your jeffies.. Stash this under "features".

Had this still installed so tested: spring 0.82.7.1 with ba750.sdz
jeffies miss each other from time to time, also the damage is not always the same. (in one case a hit only did 1% damage)

That's because all lasers in BA are boned by minintensity causing damage values to be all over the place.

Jeffy/Weasel lasers are made up of a few shots over time, each hitting for part of the total damage. In the time between these shots the turret does not adjust it's angle to stay on target if the target and/or jeffy is moving. A diagram:



If you imagine that the target was an enemy jeffy moving in the opposite direction, you can see how it could've easily only been hit by 1 of the shots, with the remaining 4 (carrying most of the damage) completely missing.
