after effects wiggle expression y axis only

You could do it all on one line, but it gets a bit hard to read:, comp('Main COMP').layer('text').transform.position, comp('Main COMP').layer('text').transform. The first line is just for convenience - it assigns the position property as the value of the variable myPos. Blink expression After Effects: To get a random blink action for an eye in After Effects, you need an After Effects Eye Blink Expression. Where offset is whatever your offset is, obviously. Thus: thePos = comp('Main COMP').layer('text').transform.position So you need to unpick the original array using the foo, foo… notation and then put it back together as an array using the notation. In your case you want just the third component to have the offset. But you probably don't need to worry about that at this point. Arrays can also be multi-dimensional, so the address could be foo for a three dimensional array. This works but wiggles on both the x and y axis. The first for the frequency and the second for the amplitude. I wanted to apply the wiggle expression to the Y Position of a layer. Note that the index starts at 0, so to get the first component of the array you would use foo, the second foo and so on. How would I use the wiggle expression only on the y-axis I'm using two sliders.

TL DR to create an array you put a number of comma-separated values in square brackets.Ĭonversely you can access any of the components of an array using this notation: foo where foo is the name of the variable, and n is the index of the component you want. To specify an array you use this notation foo = where A, B and C are the individual values – constants, variables, whatevs. The position property is an array, which is a container with a number of components in it, in this case the three position values: x, y and z.
