Exponential	1	Gain = (Distance / ReferenceDistance) ^ (-RolloffFactor)
Inverse	2	Gain = ReferenceDistance / (ReferenceDistance + RolloffFactor * (Distance - ReferenceDistance) )
Linear	3	取得 = (1 - RolloffFactor * (Distance - ReferenceDistance) / (MaximumDistance - ReferenceDistance) )

備註

Gain從 0 到 10 的圖表，包含： ReferenceDistance = 5 、 RolloffFactor = 0.5 和MaximumDistance = 20
