script to get only x position..and what does “++” do?
hi, I know
var myLayerPosition = myLayer.position;
would return an array..
but how do I just get the x value?
I know in expressionland it’s “position[0]”. I tried that, but for som reason it doesn’t seem to manipulate the data the same…?
also, what does “++” do? I know it ‘incriments’, but I’m not sure what it really does. I see it in many scripts.

I should mention I’m trying to write a script, that when activiated, will simply move a layer from it’s current position up 10 pixels. And everytime it is run it will move the layer up 10 pixels.

How about writing this for position:
[position[0], position[1]-10]
Haven’t tested it.

I believe that is correct, I will test it now. Thanks for the help, sir.

This script will do what you want. It assumes your layer is selected:
var myComp = app.project.activeItem;
var myLayer = myComp.selectedLayers[0];
var myCurrentPos = myLayer.property(“position”).value;
myLayer.property(“position”).setValue(myCurrentPos – [0,10]);Dan

Much better than my expression. 🙂

++ is called the “increment operator”. Basicially all it does is add one to a variable. — is the “decrement operator.” Let’s say you had a variable called i.
i++;
is the same as saying,
i = i + 1;You will see the this kind of thing most often when you are using loops. Hope my info was what you were looking for.
