Combinator which can read entity

Post by DirtyBitch »

It would be awesome to have combinator which can read neigbour entity like a SINGLE train wagon or a car or a tank and output it on wire.

mods have to implement this in a really performance intensive manner, but the base game could implement it as a part of the entity update.

Linear search and overflows are indicative of sloppy coding practices.

Yes, polling trains (in manual mode) and cars really hurt performance. That's why IS has an option to only read automatic trains, which is a fair bit better than polling every n ticks.
Reading entire trains from train stops though is the way to go.

or use a buffer box at each wagon and measure that - it'll indicate when one is empty and the others aren't

doesn't it poll every n ticks even for automatic trains?

Technically yes, but it reads from a cached entity and doesn't have to run find_entities to see if the thing is still there.
