Again with the counting down…
Hey hey AE masters–
First off I have to thank you soo much, you’ve helped guide me through virtually everything I’ve needed to know.
This is the first time I’ve had to post, nonetheless…here it is-
I just want to make a simple countdown from 50 to 00. I think I’m over-complicating it, but expressions simply aren’t my dig yet.this is what I have in the “source text” property-
Math.ceil(50-(time*15));
i know that by writing it this way, everything is being based off my timeline, so if there’s another way I’m overlooking that would solve the problem below ?here’s the problem-
it counts into negative numbers. so I have to give it an if/else property and I can’t seem to get it to where I want. The expression above counts at the correct speed for me, I just can’t get it to stop.Any suggestions?!! Please help!
Thanks-
BS———-

Hi Hero, there are different ways to approach this:
something like this:
t=Math.ceil(50-(time*15));
if (t>0) {
t
} else {
0
}
there’s a shorthand version of if/then/else too:
t=Math.ceil(50-(time*15));
t>0 ? t : 0 ;
or with a Math.max() function:
Math.max(Math.ceil(50-(time*15)) , 0);
(returns whichever of two numbers is the highest: your calculation or zero: this eliminates negative numbers.or (the most versatile and simplest) use linear()
Math.ceil(linear(time, 0, 50/15, 50, 0)):
meaning this:
for time (parameter 1)
if time=0 (2nd parameter), return 50 (4th parameter).
if time=50/15 (3rd parameter), return 0 (5th parameter).
for every time-value inbetween do a linear interpolation.Powerful stuff once you get your head around it.
