| current | The current position. |
| target | The position we are trying to reach. |
| currentVelocity | The current velocity, this value is modified by the function every time you call it. |
| smoothTime | Approximately the time it will take to reach the target. A smaller value will reach the target faster. |
| maxSpeed | Optionally allows you to clamp the maximum speed. |
| deltaTime | The time since the last call to this function. By default Time.deltaTime. |
Gradually changes a value towards a desired goal over time.
The value is smoothed by some spring-damper like function, which will never overshoot. The function can be used to smooth any kind of value, positions, colors, scalars.
