static |
Updates the given scalar towards the given target using a smoothing function.
The given response time determines the amount of smoothing (lag). A longer response time yields a smoother result and more lag. To force the scalar to follow the target closely, provide a response time that is very small relative to the given elapsed time.
x | the scalar to update. |
target | target value. |
elapsedTime | elapsed time between calls. |
responseTime | response time (in the same units as elapsedTime). |
