loop in AND loop out
Hi! New problem …
I have a project where some layers rotate around a globe (it’s not for me, it’s for a training session I give!)
and here is my problem: I wrote an expression to loop my rotation loop_out(“cycle”,0) and, of course, it works. Now, I wanted to have the same rotation withe a loop in. So I added a line to my expression:loop_in(“cycle”,0)
loop_out(“cycle”,0)and it doesn’t work. I have a loop in OR a loop out but I can’t have them both on the same layer. May be I should add something between my two expressions?
Any ideas?Thank u guys

what’s happening is the last statement is the one that ae will execute. so, loop_out is the only one you will see.
what you’ll need are some conditional statements that will make each statement get executed when certain criteria is met — essentially, when time is less than when the rotation starts, loopIn; when it is after rotation ends, loopOut; if it is in between the keys, return the actual values…
something like this should work:
if (time=key(numKeys).time){
value;
}else{
if (timekey(numKeys).time) loopOut();

oops, part of the expression was removed due to the symbols…
lets try this again:
if (time < key(1).time) loopIn();
if (time >= key(1).time && time <= key(numKeys).time) value;
if (time > key(numKeys).time) loopOut();that looks better, and it’s a little simpler than the original

Yessss it works!
Thank u. I thought it would have been easier but … expressions are always a pain in the ….
However, I wouldn’t have find it by myself so … thank u

Kevin that expression work is formidable. Really good stuff.
whilst messing around with the expression to understand how it works I found you can reduce your code slightly into this…
if (time < key(1).time) loopIn(“continue”);
else (value);
if (time > key(numKeys).time) loopOut(“continue”); -
also this would work:
loopIn()+loopOut()-valueRoei Tzoref

more like this:
loopIn(“continue”)+loopOut(“continue”)-value
