adding a value to a subsequent layer’s property
I have a text layer which I’ve put an opacity text animator.
I’m using opacity to reveal each letter one at a time using the offset parameter.
So with a start of 0 and and end of 1 and offset at zero, the first letter of my text line is visible.
I can dupe my layer and set that layer’s offset to 1 and that will reveal the second letter.What i want is an expression that I can put on the 1st layer’s offset so that each time I dupe the layer the new layer will have the offset value increase by one, so that all I have to do is keep hitting apple-D and all my letters will be revealed on it;s own layer,
I suppose what i really want is how to do this with all sorts of parameters.
Say I want each duped layer to be 10 bigger in scale than the previous, etc.
Thanks!

Just use the layer’s index, which is the same as its number in the timeline window. For your scale example you could do it like this:
[10,10]*index
Layer 1 will be at 10%, layer 2 will be at 20%, etc.
If you want the largest layers at the top of the stack, you’ll have to do something like this:
n = thisComp.numLayers;
[10,10]*(n + 1 – index)Depending on what you’re doing, you text animator expression might be as simple as this:
index
