| current | 現在位置 |
| target | The target position. |
| currentVelocity | The current velocity. This method modifies the currentVelocity every time the method is called. |
| smoothTime | The approximate time it takes to reach the target position. The lower the value the faster this method reaches the target. The minimum value is 0.0001. If a lower value is specified, it is automatically clamped to this minimum value. |
| maxSpeed | Use this optional parameter to specify a maximum speed. By default, the maximum speed is set to infinity. |
| deltaTime | The time since this method was last called. By default, this is set to `Time.deltaTime`. |

This method smoothes the value with a spring-damper like algorithm that never overshoots the target value. This algorithm is based on Game Programming Gems 4, Chapter 1.10.
Note: This method attempts to avoid overshooting the target value. When deltaTime is 0.0f, this yields NaN for the currentVelocity. If you call back with a currentVelocity of NaN, this method returns a NaN.
