Looping in After Effects

I have once again been working in the wonderful world of looping animation. This time I'm working in After Effects and have a lot more keyframes to play with. One thing that I noticed is that I can't use a loopIn and loopOut command in the same expression. This would make offsetting much easier so I did a bit of googling.

To add an expression to a property in After Effects, simply Alt+Click the stop watch on it.


Here's the expression that works, thank you Kevin Camp:

if (time < key(1).time) loopIn();
if (time >= key(1).time && time <= key(numKeys).time) value;
if (time > key(numKeys).time) loopOut();
