Battlefield 1 General Information

• Each shot adds RecoilUp degrees to vertical aim (pitch)
• Each shot adds

  random_uniform(-recoilLeft, recoilRight)

  to horizontal aim (yaw), positive being clockwise.
• Recoil decrease per one logical frame per one axis (ver. or hor.) is calculated as follows:

    CurrentRecoil = Current amount of recoil (either ver. or hor.)
    RecoilDecrease = Weapon's recoil decrease value
    DeltaTime = Time since last logical frame (seconds)
    TimeSinceLastShot = Time since last fired shot (seconds)
    C = Some constant (approx. 5.0)

    RecoilTerm = ((abs(CurrentRecoil) / 0.5)^0.6 + .001) 
    Decrease = RecoilTerm * RecoilDecrease * DeltaTime * TimeSinceLastShot^0.5 * C

    NewRecoil = (CurrentRecoil - Decrease) if CurrentRecoil > 0 else (CurrentRecoil + Decrease)

• Note that vertical and horizontal recoil are independent, and both get decreased with same equation.

• If spread > 0.0, shot will have random dispersion from the aimpoint. Spread = radius of the circle used for random selection.
• Random dispersion based on current spread value per shot is calculated as follows:

rand1 = rand(0,1)
rand2 = rand(0,2*PI)
horizontal_dispersion = rand1^a * spread * cos(rand2)
vertical_dispersion   = rand1^a * spread * sin(rand2)

• Where

  a = 0.5

  for all weapons. Due to this the dispersion is evenly spread out.
• Note: Shotgun pellets have

  a = 1.0

  , and thus are more tightly spread out near the firing direction, which is first decided by the above shot dispersion.

Each shot adds spreadIncrease to spread.

Spread will start to decrease when weapon is ready to fire next shot at the rate of spreadDecrease/second.

• Bullet accelerates towards ground at Gravity m/s²
• Bullet slows down at Bullet_Velocity² * Drag m/s

• Deploy Time is the time it takes to weapon be able to fire after switching to said weapon.
