relative to global acceleration conversion...

like this:

TFormVector RelativeXVel#,RelativeYVel#,RelativeZVel#,camera,0
GlobalXVel# = TFormedX()
GlobalYVel# = TFormedY()
GlobalZVel# = TFormedZ()

oh, and by the way... its velocity that changes position, acceleration changes velocity:

xaccel# = 0.0
yaccel# = -10.0
zaccel# = 1.0

xvel# = xvel# + xaccel#
yvel# = yvel# + yaccel#
zvel# = zvel# + zaccel#

xpos# = xpos# + xvel#
ypos# = ypos# + yvel#
zpos# = zpos# + zvel#

catch me on irc if you want more help etc, i know a lot of useless junk like this ;)
