Description
Interpolates the value InOutX towards TargetX using a critically damped spring via an intermediate state - producing a more S-shaped curve. The velocity of X is stored in InOutV.

UFUNCTION (BlueprintCallable, Meta=(Category="Math|Spring", AutoCreateRefTerm="TargetX"))
static void CriticalDoubleSpringDampFloat

float & InOutV,
float & InOutXi,
float & InOutVi,
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 |
| InOutXi | The intermediate state of the double spring |
| InOutVi | The intermediate velocity of the double spring |
| 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 |
