Expression illiterate. Please help me with this basic expression:
I am key framing two layers of text for position, I need the bottom text layer to be the exact same position as the one on top, except the the x value needs a value of 4 added to it (to move the bottom layer 4 pixels to the right of the top layer).
Does this make sense? I can’t figure out the expression language and key framing them all is cool but annoying, and this seems like a perfect time to learn a simple expression to train my expression feeble mind. Thanks a lot in advance.

x = thisComp.layer(“name”).transform.position[0]+4;
y = thisComp.layer(“name”).transform.position[1];[x, y]

In Motionscript, you can add two vectors simply together like this:
[10,10] + [2,4] => [12,14]
since the position contains a vector, the expression can be as simple as:
thisComp.layer(“name”).transform.position + [4,0];
(this used to not always be the case – 5.5 ? -there was a function called Add or vectorAdd, or something like that)

Nice info, Filip! I guess this function was addVector(?).
I really like the variables. Even this being a simple expression, I have to simplificate it. Since I started to study Dan Ebberts’ Motion Script.com, I started creating variables to everything.
They are really useful and the best is that we can add a lot of names to them and it is easy to memorize.Lord Scales

If the text layer is 3D, it’s as simple as adding a z vector, no?
thisComp.layer(“name”).transform.position + [4,0,0];
Thanks again. Extremely helpful.
