Smoother piece attachment visuals (and even physical locations?)


The units in that gif are carrying structures via Spring.AttachUnit. They visibly lag quite a distance behind the underlying pieces, as the arms of the units move left and right as they walk. It would be a great improvement for modular unit games, or things such as big ship with constructable hardpoints, if units were a bit better at updating their position to the underlying pieces. I'm aware that things like frame interpolation are likely to make the problem not entirely solvable, but perhaps there is something cheap to try that would still be a noticeable improvement.

Start by reproducing the attached GIF behavior with Spring.AttachUnit and trace how attached units update their positions relative to underlying pieces. The payload names no source file or test, so locating the relevant attachment and animation update paths is part of the investigation. Done means a noticeable reduction in visible lag, with the result checked against the reported modular-unit scenario.
