Expression Count Up Percentage

[Joshua Bird]

Hi Dan,

Worked perfect. Thank you. So I can learn more about the coding structure for AE can you explain what each number in this string represents (v1, 87, 100, 0, 100)?

Does:
v1 rep the opacity of layer 1 at any given time
87 target start value of layer 2
100 end value of layer ?
0,100 change opacity of layer 2 from 0-100

Thanks,

Josh

>v1 rep the opacity of layer 1 at any given time

Yes.

The second line of the expression essentially says “as the opacity of layer 1 varies from 87 to 100, vary the opacity of this layer from 0 to 100”. It’s in the AE help manual under Interpolation methods.

Thank you again. I will look this up.

Best,

Thanks for all the good advice so far. But how is it possible to make the percentage “slider controllable”?

Basically what I wanna do is take this: https://vimeo.com/108922785 and add a fourth number, that is being controlled be a sum of two of the other numbers. But I can’t figure it out how to add the two numbers on top of each other. So I either need to understand that, or come up with a way to have a slider on my text layer that simply controls the number.
