Description
Interpolates the value InOutX towards TargetX with the motion of a critically damped spring. The velocity of X is stored in InOutV.

UFUNCTION (BlueprintCallable, Meta=(Category="Math|Spring|Experimental"))
static void CriticalSpringDampFloat
(
float & InOutX,
float & InOutV,
const float & TargetX,
float DeltaTime,
float SmoothingTime
)
Parameters
| Name | Remarks |
|---|---|
| InOutX | The value to be damped |
| InOutV | The speed of the value to be damped |
| TargetX | The goal to damp towards |
| SmoothingTime | The smoothing time to use for the spring. Longer times lead to more damped behaviour. A time of 0 will snap InOutX to TargetX |
| DeltaTime | Timestep in seconds |
