The spring strength determines how hard it will pull towards the target. The value is the frequency at which it will oscillate when there is no damping.
The amount of damping in the spring. Set it smaller than 1 to make the spring oscillate before stabilizing on the target. Set it equal to 1 to reach the target without overshooting. Set it higher than one to make the spring take longer to reach the target.
If true, then the Current input will be used to initialize the state, and is required to be a variable that holds the current state. If false then the Target value will be used to initialize the state and the Current input will be ignored/unnecessary as a state will be maintained by this node.
The amount that the velocity should be passed through to the spring. A value of 1 will result in more responsive output, but if the input is noisy or has step changes, these discontinuities will be passed through to the output much more than if a smaller value such as 0 is used.
