Would modifying the white box accordingly bee a problem? So when you have Q’s, the white box would also be higher?

Try this:

Draw your area as a Shape Layer. Make sure to add fill to it.
Name it “Area” for the expression to work. Choosing another name means you must change the name in the expression too.

Make a text layer. Add this expression to the text field.


layerCount = 0;
startCount = 2; //index of the first counted layer
stopCount = 5; //index of the last counted layer
target = thisComp.layer("Area");
for(var i = startCount; i<=stopCount;i++){
if (target.sampleImage(thisComp.layer(i).transform.position,[1,1],true,time)[3] == 1) {
layerCount++;
}
}
layerCount;

Put this expression to your anchorpoint


var top = sourceRectAtTime(time,false).top;
var myHeight = sourceRectAtTime(time,false).height;
var y = top + myHeight/2;
[value[1],y]


If you want the anchor point to be in the middle vertically as well as horizontally use this:


var left = sourceRectAtTime(time,false).left;
var top = sourceRectAtTime(time,false).top;
var myWidth = sourceRectAtTime(time,false).width;
var myHeight = sourceRectAtTime(time,false).height;
var x = left + myWidth/2;
var y = top + myHeight/2;
[x,y]

If you want to use your new line for any shape(not just a rectangle), just use and index instead of the name. Something like:


c = content(1).content("Fill 1").color


If you want to find out exactly what index that is, I suggest installing “GimmePropPath” script form redefinery.com. Actually, if you want to continue doing scripting, you should definitely install that script.
Here’s a link for a collection that contains GimmePropPath and a bunch of other really cool scripts.

You can’t access the position of a letter or a word inside a paragraph.

What do you mean use them like toggle hold keyframe? To have the slider the value of first keyframe until it reaches the second and then snap to that value?

And if you want to rename the markers as you please, you can re-create those 2 keyframes and add this expression instead. The values are now taken from the keyframes.


v1 = valueAtTime(key(1).time);
v2 = valueAtTime(key(2).time);
t1 = marker.key(1).time;
t2 = marker.key(2).time;
(isNaN(v1+v2)) ? value : linear(time,t1,t2,v1,v2);

If you plan to use it like this, you don’t even need keyframes. This expression will take the values from the markers comments. Just make sure the comments are always a number.

v1 = parseInt(marker.key(1).comment);
v2 = parseInt(marker.key(2).comment);
t1 = marker.key(1).time;
t2 = marker.key(2).time;
(isNaN(v1+v2)) ? value : linear(time,t1,t2,v1,v2);

You can’t move layers with expression. But i think you could do this:

Set all layers start point and end point equal.
Make 3 sliders(duration of A, B and C);

So let’s say you have the “Controls” layer that has 3 sliders, “Text A”, “Text B” and “Text C”.

Write this in the opacity expressions of the layers.

Text A

s = inPoint;
d = thisComp.layer("Controls").effect("duration A")("Slider");
(time > s && time < s+d) ? value : 0;


Text B

s = inPoint+thisComp.layer("Controls").effect("duration A")("Slider");
d = thisComp.layer("Controls").effect("duration B")("Slider");
(time > s && time < s+d) ? value : 0;


Text C

s = inPoint+thisComp.layer("Controls").effect("duration A")("Slider")+thisComp.layer("Controls").effect("duration B")("Slider");
d = thisComp.layer("Controls").effect("duration C")("Slider");
(time > s && time < s+d) ? value : 0;

Try this

text.sourceText.style.setFontSize(100)

The style belongs to the ‘sourceText’ Class, not in ‘global’ Class.
