Chris's expression woul= d do what you're looking for. Set 'minx=3D' and 'miny=3D= 9; to whatever you want the minimum value to be. As your slider goes from 0= to 100, the value will change from [minX, miny] to the keyed value.

Rereading now and do you want to use the slider as a mu= ltiplier? So when the slider is at 1 the object is on the path... At 0 the = object would be at =C2=A00,0,0 =C2=A0at 2 the object would be double the po= sition of the current time?

[x,y]


Is this what you mean?=C2=A0

Sort of like scaling the entire motion path of keys in one o= r all directions, but tying that to a slider, so that when the slider is at= 0, there is no motion. ie it clamps all values to 0.

There is probably an easier way to do this but I was wondering if this= it was possible like this. Thanks,
