Hello, I have a question about the keyframe expression
First of all, I apologize in advance for my unskilled language.
What I’m curious about is I added a checkbox to the keyframe to enable on/off
but Here I would like to know an expression to add a slider to adjust the keyframe rate
with a slider
Below is the expression I wrote
I want to know where it went wrong
———————————————-
if(effect(“lightwhip”)(“check”)==true){
time*thisComp.layer(“Effect”).effect(“slider control”)(“slider”)
nearestKey(thisComp.duration)
}
else {
value
}
——————————————————————————

Fortunately
I found a way to adjust the speed at the keyframe,
but
I found a speed control on keyframes
I don’t know how to add a check box expression here
———————————————————-
spd =thisComp.layer(“Effect”).effect(“slider controll”)(“slider”);
accum = 0;
for (i = timeToFrames(inPoint); i <= timeToFrames(time); i++){
accum += spd.valueAtTime(framesToTime(i));
}
value + accum*thisComp.frameDuration;
——————————————————————-
Please let me know how to add the expression below here.
——————————————————————————–
if(effect(“checkbox control”)(“check”)==true)

Place it where you need to use it
Maybe here:
spd = thisComp.layer('Effect').effect('slider controll')('slider');
accum = 0;
if (effect('checkbox control')('check')) {
for (i = timeToFrames(inPoint); i <= timeToFrames(time); i++) {
accum += spd.valueAtTime(framesToTime(i));
}
}
value + accum * thisComp.frameDuration;

The above information was put in the expression as it is, but in the check box It doesn’t seem to work to turn keyframes on and off What should I do..??

The position is still moving. How can it not move when the check box is turned off?
