c_move(me,vector(0,shot_speed*time,0),vector(0,0,shot_gravity*time),ignore_models);
- - - should be - - -
c_move(me,vector(my._shot_speed*time,0,0),vector(0,0,my._shot_gravity*time),ignore_models);

I'm not sure if you can assign a function to an entity, so try this...

Code:

---

 

action fShoot
{
    my.enable_impact = on;
    my.event = fShootEvent;
    while(my != null)
    {
        c_move(me, vector(0, my._shot_speed * time, 0), vector(0, 0, my._shot_gravity * time), ignore_models);
        my._shot_gravity -= 0.05;
        wait(1);
    }
}

function fShootEvent()
{
    if (event_type == event_impact)
    {
        my.event = null;
        wait(1);
        ent_remove(me);
    }
}

    ...
    temp.x = 65;
    temp.y = 0;
    temp.z = 5;
    vec_rotate(temp.x, my.pan);
    vec_add(temp.x, my.x);
    you = ent_create(sShot, temp.x, fShoot);
    you._shot_speed = my._shot_speed;
    you._shot_gravity = my._shot_gravity;
    ...
