Offset timing of 3rd and 4th Keyframe via slider
Hi there
What I would like to do is to control what time the 3rd and 4th keyframes (one second apart) begin via a slider.
e.g. If the slider value is 4, then the 3rd keyframe will start at 4 seconds and the 4th keyframe is at 5 seconds.
If the slider value is 10, then the 3rd keyframe will start at 10 seconds, and the 4th keyframe will be at 11 seconds.etc. etc.
I want to keep all the easing I already have between the two if that is possible.
So far I’ve been messsing around with:
if (numKeys > 2){
dur = (effect(Slider Control")("Slider"))
t = time - dur
valueAtTime(t)
} else
valueThis is sort of doing it but not quite…
Any suggestions would be awesome!
Thanks
James

SOLVED!
After more searching I’ve found an old post with something that will work:
Instead, this uses a slider to hold the values between 2nd and 3rd keyframes…
holdTime = effect("Slider Control")("Slider");
k1 = 2; // 1st hold keyframe
k2 = 3; // 2nd hold keyframe
p = transform.position;
t1 = p.key(k1).time;
t2 = t1 + holdTime;
if (time < t1)
t = time
else if (time < t2)
t = linear(time,t1,t2,t1,p.key(k2).time)
else
t = p.key(k2).time + (time - t2);
valueAtTime(t)The old post for reference:
