Slider Control to adjust position
Hi, Im very new to AE, but im currently learning expression controls.
Im working on an animation on a character where i want the ear move between 2 points, A = 1088, 766 and B = 980, 952, rather than moving the ears manually each time i would like to use a slider control.
I’ve tried pick whipping “position” to the slider but that just moves the ear to 100,100 and when i move the slider it moves the ear up and down equally 101,101 – 102,102 – 103,103 etc etc)
Is their a way to create a pre-defined path for the object to follow using the slider?
I hope ive made sense. All new and complicated to me.
Thanks,
Ben

This will move the layer between A and B as the slider goes from 0 to 100:
s = effect(“Slider Control”)(“Slider”);
A = [1088,766];
B = [980,952];
linear(s,0,100,A,B)Dan

Thanks Dan!
Ive put that into the expression box for “position” on the ear layer? Is that right as i get an “expression disabled error?
Would you be able to explain what that code “means”, so i can try and get my head around expressions.
Thank you again 🙂

Oh wait, ive sorted it! I just had to pick whip the “effect(“Slider Control”)(“Slider”);” bit!

Would i have to do anything different if i wanted this movement controlled by the angle control so position A = 0 and position B = 360?
Ive tried this code but it doesnt work:
s = thisComp.layer(“Control”).effect(“Ears”)(“Angle”);
A = [1088,766];
B = [980,952];
linear(s,0,360,A,B); -
It works the way I would expect it to. What does is it doing for you? Are you getting an error message?
Dan
