setAccuracyFalloff(NewWeaponType, FALLOFF/RANGE, PERCENTAGESTART);

//Same as damage falloff. For Homeworld 2 style bullet steering, it acts as a multiplier against the weapon accuracy against its target, reducing the chance the bullet will steer into its target. For ballistics enabled weapons it acts as a multiplier against the weapon accuracy against its target, reducing the chance the bullet will be considered an aimed shot if it strikes its target.
