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?

Not sure I understand 100%, but it sounds like you would use a slider to co= ntrol the interpolation between the layers actual position, and a minimum o= r maximum amount. =C2=A0So if you have a slider called "Amount 0-100&q= uot; your position expression would be:

p=3Dtransform.position;
x=3Dp[0];y=3Dp[1];

minx=3D0;miny=3D0;

slider=3Deffect("Amount 0-100")("Slider");
x=3Dl= inear(slider,0,100,minx,x);
y=3Dlinear(slider,0,100,miny,y);

[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,
