float chrampderiv(string channel, float ramppos)
float chrampderiv(string channel, float ramppos, float time)
vector chrampderiv(string channel, float ramppos)
vector chrampderiv(string channel, float ramppos, float time)
Evaluates the derivative of a parm parameter with respect to position.
The ramppos is where on the ramp to evaluate.
The time parameter can be used if the ramp is animated to evaluate at other than the current time. Note that this does not take a derivative with respect to time.
