FunctionsmoothDamp

smoothDamp(current, target, velocity, smoothTime, deltaTime): [number, number]
Dampens a current value back to a target value with spring-damper behavior.
Parameters
- current: number
  the current value (usually position along an axis)
- target: number
  the target value to dampen to
- velocity: number
  the current velocity (usually speed along an axis)
- smoothTime: number
  the time it should take to smoothen to the desired target
- deltaTime: number
  the amount of time passed since last frame
Returns [number, number]
the smoothened value and new velocity: [position, velocity]
