Fields
| Name | Value | Description |
|---|---|---|
| Exponential | 1 | Gain = (Distance / ReferenceDistance)^(-RolloffFactor) |
| Inverse | 2 | Gain = ReferenceDistance / (ReferenceDistance + RolloffFactor * (Distance - ReferenceDistance)) |
| Linear | 3 | Gain = (1 - RolloffFactor * (Distance - ReferenceDistance) / (MaximumDistance - ReferenceDistance)) |
Remarks
Graph of Gain as Distance ranges from 0 to 10 with: ReferenceDistance = 5, RolloffFactor = 0.5, and MaximumDistance = 20
