Loop keyframes gains over time
for example: I have a walk cycle of a character that bobs up and down between two keyframe as well as position move about 50 pixels to the left. Well I want that motion to loop again and again but at the same time move another 50 pixels every time it loops so it makes its way off screen. How would i go about creating a loop that gains over time? I have found an expression where you can choose which keyframes to loop and how many times, so i figured that would be a good start but how would i be able to have it gain every time it loops?
if (numKeys > 1){
nLoops = 5;
t1 = key(1).time;
t2 = key(2).time;if (time < t1)
value
else if (time < t1 + nLoops*(t2-t1))
valueAtTime(t1 + (time - t1)%(t2-t1))
else
valueAtTime(t2 + time - (t1 + nLoops*(t2-t1)));
}else
value -

Have you tried loopOut(“offset”) ?

Oh damn, BOOM!. Done. Perfecto. Do you think there is a way to include it into the expression in the initial post? For example: having 4 keyframes and wanting the last 2 keyframes to loopOut(“offset”)?

As I recall, this should loop the last 2 keyframes:
loopOut(“offset”,1);

Ding Ding Ding. Its like obvious-ville for you huh. Simplistic expressions sometimes just escape my grasp. Thanks Again. So to add on to this procedure how would i go about stopping the loop after 5 loops and maintain its last position of the loop?
Once again thank you for you expedience and knowledge.

Hmm…
I think that starts to look more like your original expression:
nLoops = 5;t1 = key(numKeys-1).time;
v1 = key(numKeys-1).value;
t2 = key(numKeys).time;
v2 = key(numKeys).value;
if (time < t2 + nLoops*(t2-t1))
loopOut("offset",1)
else
v2 + nLoops*(v2-v1)
