    Expression to parent X & Y position values only?

    Posted by Tim West on April 13, 2010 at 10:09 am

    Hi,

    I am trying to create an expression that parents the X & Y position of one null (‘A’) to the X & Y position of another null (‘B’) only – I want to be able to animate the Z postion of null A independently.

    Can anyone show me how to write this expression?

    Any help much appreciated,

    Thanks for your time,

    T

    On the position attribute of null A:

    L = thisComp.layer("Null B");
LP = L.toWorld(L.anchorPoint);

[LP[0], LP[1], value[2]];

    -Ben.

    Is it possible to get this working on a slider controlling X only?
