Virtually identical to STOR, but instead acts on CTYPE, not TYPE.
Passes stored elements to PIPE/PPIP.
CTYPE determines the CTYPE of allowed particles.
PSCN allows elements to pass through, just like STOR.
Uses:
Material Refineries. Now, you don't need a complex temperature control system to sort out elements! You could just heat everything up to max temperature, and let SORT do the rest.
Liquid/Powder Sorting. Sorting LAVA, BREL, and SNOW could never be easier.
This seems pretty niche. For powders you could cool them down to sort. For solids, still wouldn't be able to sort, but you're going to have a hard time sorting melted solids anyway.
Not every element uses ctype, it's mostly only the meltable / sparkable ones. Some elements also use it in unusual ways like GLOW (which should probably be fixed). Sorting on ctype is a little weird for that reason.
Maybe there just needs to be better ways to sort lava. Could have the .Weight of the original elements factor in to lava movement.
