i know about cray making filt set tmp. but i dont know how i should make cray manipulate the other properties instead!! (not life, even tmp2, tmp3, tmp4!!) yeah, but how about setting other particles (instead filt)'s property to v??
ctype: 0x07D <- FILT, SET
ctype: 0x27D <- FILT, AND
ctype: (tmp << 9) + 0x7D <- FILT, tmp
life: life <- life
temp: temp <- temp
others: you can't
dang it
