X, Y scaling
Hi there, I’m fairly new to expressions and I’m having a problem due to not properly understanding the syntax.
I need to use a null object slider to control the multiplication factor of a scale parameter, when I hooked it up it’s only scaling the x axis. I understand this is because it’s an array function but I can’t work out how to declare it properly.
Can anybody correct this for me?
This is the exp that works with just the X axisvalue+(20*thisComp.layer("Rig 2").effect("L - R")("Slider"))
This is my attempt at declaring the same value for the X & Y scale axis.
x = value+(20*thisComp.layer("Rig 2").effect("L - R")("Slider"));
y = value+(20*thisComp.layer("Rig 2").effect("L - R")("Slider"));
[x,y] -

Try it this way:
s = 20*thisComp.layer(“Rig 2”).effect(“L – R”)(“Slider”);
value + [s,s]Dan

Thanks Dan, that worked.
How come [x,y] didn’t work though? Or was it the value plus when I declared the variable the issue?

You were adding a scalar (the slider) to an array (value) so you were only affecting the x part of value.
