Null control with different speeds on X and Y
I want to control an object with a null so, that the object would move at different speeds on X and Y. I thought this would be fairly simple with the techniques I’ve learned.
I thought I separate the x and y and just give them a different multiply. But it didn’t work.What am I doing wrong?
x=thisComp.layer("Null").transform.position[0]
y=thisComp.layer("Null").transform.position[1]
transform.position[0]+x*1.5
transform.position[1]+y*1.8 -

I think this is what you’re trying to do:
x=thisComp.layer(“Null”).transform.position[0];
y=thisComp.layer(“Null”).transform.position[1];
value + [x*1.5,y*1.8]Dan

Great, it works!
Just one basic question: why didn’t my version work? It seems to be trying to do the same thing.
Is it because I have to wrap, or calculate the code in one “sentence” or line?so when I have my version:
transform.position[0]+x*1.5
transform.position[1]+y*1.8It doesn’t work, because they are not calculated at the same time? Does everything have to be inside one equation?
Like in your version? -
The result needs to be a two-element array for a two-dimensional property. This would have worked:
[transform.position[0]+x*1.5,transform.position[1]+y*1.8]

Aha, ok, seems familiar. Two element array and a comma dividing the elements. In your version you just gathered the two dimensions into “value” and + (x,y) with the multiplys are the two elements.
I know I got it, just have to digest it a bit.
Thank you Dan, you’re very helpful.
