Offset blinking expression
I’m using a blinking expression inside an ‘else’, but it starts with a random value when it reaches the ‘else’. How to make the blinking start at zero? (I dont know the exact time that will reach the else).
This is an example in the source text:
var anyTime = 2.28;
var cursorSpeed = 10;
if (time < anyTime) {
time;
} else {
var blinking = Math.abs(Math.sin(time * cursorSpeed));
"blinking: " + blinking.toFixed(2)
}

Try changing this line:
var blinking = Math.abs(Math.sin(time * cursorSpeed));
to this:
var blinking = Math.abs(Math.sin((time-anyTime) * cursorSpeed));

Is the var anytime equals to the total time of an animation equals 2.28 or is it the time where the blinking animation will start? I suggest screenshotting some of the issues you are having with it so we can better understand how we can help you out on this. For now I do have a video about ValueAtTime expression that may be able to help you a bit. Here it is below:

I tried something similar but it didn’t work.
Here is the full expression in the opacity animator, so you can understand better:
(‘startAnimationTime’ in the expression below is always zero, so the blinking still starts at a random value)var cursorSpeed = 10;
var startAnimationTime = 0;
// animation happening here
if (thisLayer.name.length > text.sourceText.length) {
startAnimationTime = time;
100;
} else { // animation ends here
var elapsedTime = time - startAnimationTime;
var blinking = Math.abs(Math.sin(elapsedTime * cursorSpeed));
if (blinking < 0.5) {
0;
}
else {
100;
}
}
