    if statement

    Posted by Nelson Fernandes on March 13, 2009 at 9:58 pm

    Hi guys. I’m trying but not having success. What would be the correct syntax for this if statement

    if the rotation is equal 90, opacity should go to 25
    otherwise
    opacity should stay at 100

    Thanks.

    something like this should work:

    if (transform.rotation==90) 25 else 100

    [Kevin Camp] “something like this should work:

    if (transform.rotation==90) 25 else 100”

    Kevin is correct, but I have to wonder if this is actually what you want? Using this expression the layer would ‘flash’ down to 25% opacity at 90° rotation and 90° rotation only.

    It would not go to 25% opacity at 2x 90° (810°) for example. It also would not fade into the 25% opacity.

    Perhaps this is what you wanted, but if not then you’ll need to provide more specific details for a more specific expression.
