rezing bullet issue

this one gun i scripted i think i screwed up slightly, i cant seam to be able to get the bullet to rotate horizontal it will fire out verticly and well.... ya... lol scripts dont seam to like me today

f()
{    
    vector b = llGetPos(); 
    rotation a = llGetRot(); 
    vector c = llRot2Fwd(a); 
    vector d = llRot2Up(a); 
    b += c; 
    b += d * 1; 
    c *= 70; 
    llRezObject("Bullet", b, c, <0,0,0,0>, 0);
}

is it in an attachment or a rezzed prim shooting, its possible the root prim of the "gun" is not rotated to face x forward in the direction of the gun or something like that. Ie if I rez a popgun on the ground, it often doesn't shoot forward the way it would if it was attached to my avatar.

attachment

Generic way to shoot anything from an attachment, assuming you're in mouselook:

string bullet = "Object"; // insert name here or something
rotation rot = llGetRot();
float offset = 1.5; // how many meters away from the avatar's center the bullet will actually rez
float speed = 20.0; // bullet speed

llRezAtRoot(bullet, llGetPos() + <offset, 0.0, 0.0> * rot, llRot2Fwd(rot) * speed; rot; 1);

This will also orient the projectile's x-axis in the direction you are facing.
