I don’t think it will work, because your easeInOut expression has zero velocity at the end of the ease, and overshoot depends on incoming velocity.

Try changing this line:

dis = length(this.position, mouse_layer.position);

to this:

dis = length(position, mouse_layer.position);

An expression can’t create multiple styles in a single text layer.

It doesn’t work to add loopOut() to the end of another expression. You have to create your own loop functionality–something like this:

maxOffset = 10; // frames
seedRandom(index,true);
offset = framesToTime(random(maxOffset));
t = time - offset;
if (t > key(numKeys).time){
  t = (t - key(numKeys).time)%(key(numKeys).time - key(1).time);
  valueAtTime(key(1).time + t);
}else{
  valueAtTime(time - offset);
}

Something like this:

txt = text.sourceText.value;
if (txt.length > 36)
  txt.substr(0,35) + "..."
else
  txt

There are a number of ways to do it, depending on how you’re doing the in/out animation. If you’re using 2 in keyframes and 2 out keyframes, you could do something like this to tie the animation to the layer’s in and out points:

if (time < (inPoint + outPoint)/2){
  t1 = key(1).time;
  t2 = key(2).time;
  v1 = key(1).value;
  v2 = key(2).value;
  linear(time,inPoint,inPoint+t2-t1,v1,v2);
}else{
  t3 = key(3).time;
  t4 = key(4).time;
  v3 = key(3).value;
  v4 = key(4).value;
  linear(time,outPoint-(t4-t3),outPoint,v3,v4);
}

If you’re animating in and out via expression, you’d have to alter those to incorporate the in and out point timing.

I don’t know how efficient it will be, but you could tidy things up a bit like this:

p = [];
prop = thisComp.layer("JSON")("Data")("Outline");
n = prop.numProperties;
for (i = 1; i <= n; i++){
	x = prop(i)("X");
	y = prop(i)("Y");
	p.push([x,y]);
}
createPath(p,[],[],false)

Can you post a chunk of your JSON file?

[Dan Ebberts]

The [0] gives you just the x value of the scale, which meets the requirements for the scalar value required by linear().

[Dan Ebberts]

You were close. Try it this way:

var input = thisComp.layer("Null 30").transform.scale[0];
linear(input,0,100,[0,0],[15,15]);
