how to make a period (full stop) blink?
by sean bowering on May 6, 2008 at 1:27:45 pm

hi, i'm using the typewriter effect in CS3 and i'm trying to work out how to make the period at the end of the sentence blink for a few seconds while the user reads the text and the new text comes in to replace it. is there any easy fixes, or does this involve expressions?
- apologies if this has been posted before...

why don't you try keyframing the opacity. You could use an expression, but don't need to. Just put the period on a seperate layer and animate the opacity

best of luck

thanks. i was thinking of that, but i've got approx 50 different instances of text with blinking periods to do, so that's 50+ layers to deal with... any ideas how to change the opacity of just the period using the text effect controls? i couldn't figure out how to isolate the period.

[sean bowering] "i've got approx 50 different instances of text with blinking periods to do, so that's 50+ layers to deal with... any ideas how to change the opacity of just the period using the text effect controls?"

Nope. But you only have to make ONE text layer consisting of a period with animated blinking. When you need it again, copy & paste the layer, move it in the timeline (if your timeline cursor is in the proper spot, you can do it in a keystroke) and reposition.

I bet you could do all 50 instances in 15-20 minutes, or you could spend a couple of hours trying to come up with a different solution.

In your text layer with the period type "t" for transparency, Alt/Option click on the stopwatch to access the formula, enter this:

x = Math.sin(time*10);
if (x<0) 0 else 100

You can use smaller multipliers for longer interval between blinks

Can you create a text layer just for the period?
