| `x` | N/A | The value to decay |
| `target` | 0.0 | The value at which the decay will be at its peak. For distances it is usually set at 0.0, but can be set to any value. |
| `scale` | 1.0 | The value at which the decay function will be equal to `midpoint`. This is in terms of `x` units, for example, if `x` is in meters, `scale` of 5000 means 5km. Must be a non-zero positive number |
| `midpoint` | 0.5 | Output is `midpoint` when `x` equals `scale`. Must be in the range (0.0, 1.0), exclusive |
| `midpoint` | 0.5 | Output is `midpoint` when `x` equals `target` ± `scale`. Must be in the range (0.0, 1.0), exclusive |
The formulas for each decay function are as follows:
