following on from https://forums.factorio.com/viewtopic.php?f=18&t=79206#p470859 Im looking to create a simple combinator mod that filters circuit signals by types (item,fluid,virtual) i have a rough outline of code that works on a LUA combinator 3 based on https://lua-api.factorio.com/latest/Lu...

Does anyone know a simple way of filtering out circuit signals for fluids, while i could do this with individual combinators, when i have bobs and angels, i have around 200 different fluids

in a similar way is it possible to filter out virtual signals or items as a group

Train stations Signal output appears to be rounding incorrectly have fluid wagon with each tank containing 0.5 train show content as 1.5 however a signal wire attached to train staion reads 0 i would guess train summing before rounding round(0.5+0.5+0.5) = 1.5 where as station is rounding before sum...
