addBuilding(custom type,impassible fix (bool), consumed power, produced power, list of connection points,
update skip(0/nil to disable),table of frames,frame to tick ratio (-1 for machine control))
getPower(bld) -- 2 or 0 returns, produced and consumed
setPower(bld,produced, consumed)

from here:
registerBuilding{
name -- custom workshop id e.g. SOAPMAKER << required!
fix_impassible -- make impassible tiles impassible to liquids too
consume -- how much machine power is needed to work
produce -- how much machine power is produced
gears -- a table or {x=?,y=?} of connection points for machines
action -- a table of number (how much ticks to skip) and a function which gets called on shop update
animate -- a table of
frames -- a table of
tables of 4 numbers (tile,fore,back,bright) OR
empty table (tile not modified) OR
{x=<number> y=<number> + 4 numbers like in first case} -- this generates full frame even, usefull for animations that change little (1-2 tiles)
2015-02-14 20:53:06 -07:00
frameLenght -- how many ticks does one frame take OR
isMechanical -- a bool that says to try to match to mechanical system (i.e. how gears are turning)
