Gyro_Force_ApplyFalloff_AreaLinear(entity force, vector area)
Area falloff components provide a symetrical area of effect centred at the origin of the force. The area itself is given per-axis by the area vector and determines the outer bound of the falloff, within which the decay will be applied. The simplest example of this type of falloff would be a sphere (the area vector '100 100 100'
produces a sphere of 100 radius), but more complex shapes can be created by combining several components of varying area. A value of 0
in the area vector is interpreted as infinite range and so produces no decay. Negative values are allowed, but behave identically to their positive counterparts. This particular function creates a falloff area using linear decay.
Gyro_Force_ApplyFalloff_AreaQuadratic(entity force, vector area)
This function is identical to the above but will create a falloff component using pseudo-quadratic decay. You may find it necessary to increase the strength of the force over the regular linear decay.
Gyro_Force_ApplyFalloff_AreaConstant(entity force, vector area)
This function is identical to the above but with create a constant (boolean) falloff component.
