WeaponMainDir: The Simple Way

WeaponMainDirX is a vector showing the direction of the weapon's aiming cone. MaxAngleDifX is the size of the aiming cone.

For instance, if you want your Primary Weapon to have a 90° fire arc forward, you'd write:

 WeaponMainDir1=0 0 1;  //x:0 y:0 z:1 => that's forward!
 MaxAngleDif1=90;       //90° from side to side, or 45° from center to each direction

If you want to precisely choose the WeaponMainDir, you could run UpSpring, create a new piece, move it around until the line, from the origin, to your piece, is along the line you want your weapon to fire, then write down the coordinate in WeaponMainDir. Keep in mind UpSpring invert the sign of the axis x and z.
