Remarks
Uses a simple spring model to interpolate a vector from Current to Target.
Parameters
| Name | Description |
|---|---|
| Current | Current value |
| Target | Target value |
| SpringState | Data related to spring model (velocity, error, etc..) - Create a unique variable per spring |
| Stiffness | How stiff the spring model is (more stiffness means more oscillation around the target value) |
| CriticalDampingFactor | How much damping to apply to the spring (0 means no damping, 1 means critically damped which means no oscillation) |
| DeltaTime | Time difference since the last update |
| Mass | Multiplier that acts like mass on a spring |
| TargetVelocityAmount | If 1 then the target velocity will be calculated and used, which results following the target more closely/without lag. Values down to zero (recommended when using this to smooth data) will progressively disable this effect. |
| bClamp | Whether to use the Min/Max values to clamp the motion |
| MinValue | Clamps the minimum output value and cancels the velocity if it reaches this limit |
| MaxValue | Clamps the maximum output value and cancels the velocity if it reaches this limit |
| bInitializeFromTarget | If set then the current value will be set from the target on the first update |
