Ric VieiraSONAR PING - how to reverse play direction?
by on May 19, 2011 at 4:29:07 pm

I'm having trouble with the text animator preset "SONAR PING."

It plays (or fades in) from right to left, and I want it to play from left to right!
I'm an AE CS5 newbie and cannot figure out how to do it.

Any tips, are highly appreciated, thanks.

You will need to make a minor amendment to the Expression used in the Animation Preset. Select the Text Layer and hit the "e" key twice, quickly to display the layer's Expression(s).

The existing Expression reads as -
f = effect("Frequency")(1);
(selectorValue-100) + ((textIndex + time * f) % 30) *5


All you will need to do is to add a minus sign to the front of the textIndex global variable.
f = effect("Frequency")(1);
(selectorValue-100) + ((-textIndex + time * f) % 30) *5
