wiggle expression error

[S001 A]

Hi,

I am trying to wigle only y sxis. That means its [1].

In first case the cloud changes its position,ignoring the keyframe value of  X axis. and in 2nd case cloud stops wiggling but remain in where I want it to be.

whai am doing wrong? 😥

first casesecond case

Expression 1:

a = wiggle(4,5);
[a[1], value[0]]

value[0] is the X axis, you should try:

a = wiggle(4,5);
[value[0], a[1]]

Expression 2:

a = wiggle(4,5);
[a[1], value[transform.position[0]]

value[0] = X axis value

value[1]  = Y axis value

value[2] = Z axis value

value[transform.position[0]] doesn't make sense

You should try:

x = value[0];
y = wiggle(4,5)[1];
[x, y]

Thank you so much. I was about to cry for not figuring out what is going on. 😥

value[transform.position[0]] doesn't make sense-- I learned this from atutorial. U can drag whip to Y or X or anyvalue that u wanna keep fixed in expression. Instead of writting [1], u can drag the whip to Y axis, expression will write value[transform.position[1]]

Check this--

it's:

temp = thisComp.layer("Circle").transform.position[0];

not:

temp = value[thisComp.layer("Circle").transform.position[0]];

value[0] is a shorthand for:

thisComp.layer("Circle").transform.position.value[0];
