Okay, so I got a Projectile with 2 Vectors, position and velocity. I now want to calculate the initial velocity for it in order to reach a specific point on the map.

Or actually, how high has the start z-velocity to be (because x and y are probably defined by a speed variable) in order for the projectile to hit the marked position.

The projectile is influenced by a constant gravity vector.

All calculations are done 32 times per second.

I want this, because I don't want to use a parabola function, so the projectile can still be influenced by other sources, simply adding some velocity.

I didn't really find anything referring to that topic and would be glad for every helping answer, Thanks.

What can influence your projectile while it is traveling? Gravity? other effects? Without knowing those factors we can't give you anything :) –  Roy T. Jul 1 '12 at 20:05
    
oh, sry. The only influence is a gravity vector. –  Frotty Jul 1 '12 at 20:40
