Starting with the Word Processor preset applied, open the text sub-menu. You’ll see 3 Animators in there. Duplicate the one that is called “Opacity (Reveal)”.

Open the duplicated Animator, you’ll see a selector sub-menu and an opacity parameter set to 0. Delete the opacity parameter, go to Add/Property/Fill Color/RGB. Now open the selector sub-menu, and change the expression on the offset parameter (it shall be before: effect(“Type_on”)(1) + 1) to effect(“Type_on”)(1) – 1

Now your last character shall be red, but also the cursor. To make the cursor white again, duplicate the animator you’ve just created, change the fill color to white, and change the expression on the offset parameter to effect(“Type_on”)(1)

That should do it.

You got two options at least, I guess:

1-you can play with the scale of your rectangle (in Contents/”your form”/transform) which has its own anchor point that is different from the layer transform menu.

2- You can add a Null layer, place it on the center of your rectangle, parent your rectangle to the Null. Then, scaling the Null will scale your rectangle from its center, without changing neither its anchor point nor your animation.

Ok, now I think I understand what you want to achieve. If I am correct, your expressions are ok, and the problem lies in your keyframing.

If you want your dots to be before and after your effect, both your first and last keyframes in both opacity and scale shall be at 100%.

For example, if you only want a random disappear/reappear (with a space between keyframes of ten frames every time):
on scale,
1st keyframe at 100,100, 2nd keyframe at 0,0, 3rd keyframe at 0,0, 4th keyframe at 100,100
on opacity (basically same thing)
1st keyframe at 100, 2nd keyframe at 0, 3rd keyframe at 0, 4th keyframe at 100.

From what I see from your screen, you miss at least one opacity keyframe.

What’s happening in the picture is not so clear, maybe you can send a video, or another picture of the problem?

But out of the blue, you may try to get all the velocities of the emitter to 0.

Maybe I don’t understance what you’re trying to do, but I find it very complicated. If you want your dots to fall from beyond the screen to under it like rain, with different times, position and scale, you may try a simpler kind of expressions like that (assuming your comp is in 1920×1080):

create a Null, with 2 slider control. (one renamed minStart, the other maxStart)

on position:
minStart=//pickwhip your slider control;
maxStart=//pickwhip your slider control;

seedRandom(index,true);
A=random([0,-50],[1920,-50]);
B=random([0,2000],[1920,200]);
T=random(minStart,maxStart);
linear(time,T,T+2,A,B)

on scale:
seedRandom(index,true);
S=random(0,100);
[S,S]

Maybe change the physic model from bounce to air ? Unless you do want your particles to bounce, but I can’t see why.

Maybe by using the sourceRectAtTime() expression ? It think I doesn’t work with an opacity animation, but with scale it might… Worth trying.

I think it also have some time displacement on it, to distort the text and make little glitches.

I just made a tutorial for creating a text box that will automatically adjust itself to the size of the text, I think It basically does what you want.

Hope that answers your question.

Some expressions mighty do the trick. Try this: (i suppose your animation is in HD, and that it starts at 0 and ends at 4)

AnchorPoint

seedRandom(index,true);
A=random([-3000,-3000],[3000,3000]);
B=[value[0],value[1]];
ease(time,0,4,A,B)

Scale

seedRandom(index,true);
A=random([100,100],[200,200]);
B=[value[0],value[1]];
ease(time,0,4,A,B)

Rotation

seedRandom(index,true);
A=random(0,180);
B=value;
ease(time,0,4,A,B)

Opacity

ease(time,0,4,0,100)

Paste these on all your layers.
