ok I'm trying to make a bullet move throught the air.
basicly I've got the following data to start with

SX = Starting X
SY = Starting Y
DX = Destination X sorta
DY = Destination Y sorta
V = Vilocity Along Line

and what I need is

XV = X vilocity
YV = Y vilocity

any Ideas?

Vx = Xd - Xs / t
Vy = Yd - Ys / t

t is total time. If t is not known, normalize the vector V, i.e.,

Vx = Xd - Xs
Vy = Yd - Ys
|V| = sqrt((Vx ** 2) + (Vy ** 2))
Vx /= |V|
Vy /= |V
