Sure you can. Check out the thread a few threads back called “Both in and out” in which an expression is saved as part of a preset.

Maybe have the script select all keys on the property, then delete. You could call delete as a menu command. Then you wouldn’t have to loop.

Not sure I understand exactly what you’re saying, but if you do the animation in a preComp, then you could simply use time remap to increase the speed over time in the main comp.

Yes, and you probably don’t need expressions.

Just draw your doughnut in Photoshop or with masks in AE. Duplicate it so there’s a different colored one behind it. Then add the transition “Radial Wipe” and reveal a doughnut with “Transition Completion” over the top of the other one.

You can blend it to make a slight gradient with the Radial Wipe’s “Feather”.

You could even have more than two colors by layering multiple doughnuts.

Maybe put a slider on the layer, and then add the slider’s value to your X in the expression. Perhaps something like this:

myX = thisComp.layer(“Null 3”).transform.position[0] + effect(“Slider Control”)(“Slider”);
myY = thisComp.layer(“Null 3”).transform.position[1];
[myX,myY]

Then you can adjust the slider until you get the offset to your liking.

I don’t know how other people have done it, but I just came up with this that works:

if (time > key(1).time) { loopOut(type = “cycle”, numKeyframes = 0) }
else { loopIn(type = “cycle”, numKeyframes = 0) }

[Mitch Mann]

Position expression as follows:

myRotation = transform.rotation;
myX = transform.position[0];
myY = linear(myRotation,0,90,772,172);
[myX,myY];

[Mitch Mann]

Use multiple text layers on the same line. Offset the layers with numbers, don’t offset the $.

[Mitch Mann]

… Or the poor man’s way:
Animate it between 3 points in a preComp, then have the slider control the time remap.

You could potentially have a script that you run separately that finds it for you.

I believe that if its a script (not expression), you could use “.parent”
