aenhancers

Hi,

I have been looking around everywhere for a way to do this. Essentially I would like to be able to control the speed of a null using a slider.

Something similar to:

v=effect("main_speed")("Slider");
xu=transform.position.valueAtTime(time-0.04);
xv=xu+v;
xv;

But something that works. I realise that I may have to calculate all the position values before the current time in order to calculate the new position...but I have no idea how to work that out.

I should add that I would like to be able to ramp the speed....

Any further reading, advice or links would be much appreciated.

Thanks
