if you dont need it too accurate and you want different air friction in different directions, try this:
for a sail, where the x air resitance is very high, you would do this:
variables prefixed with "r" are relative to the object, and those with "w" are world...
for a sail, where the x air resitance is very high, you would do this:
;relative friction rXfriction# = 0.2 rYfriction# = 0.99 rZfriction# = 0.99 ;loop ;entity is your sail, which gets rotated tformvector rXfriction#,rYfriction#,rZfriction#,entity,0 wXfriction# = tformedx() wYfriction# = tformedy() wZfriction# = tformedz() wXvel# = wXvel# * wXfriction# wYvel# = wYvel# * wYfriction# wZvel# = wZvel# * wZfriction#
