  • proving an output with expressions

    Posted by Duff on August 26, 2005 at 5:13 am

    Hi all,
    I’m moving deeper into expressions (although I’m still very much at the shallow end) and am wondering if there is a way to output a value into a display window. Not for actual output in my movie, just as a reference to help me learn expressions. Flash has a similar function which helped me heaps when I was working my way through tutorials….

    For example:
    n = this_comp.layer(“Null 1”).effect(“Slider Control”).param(“Slider”).num_keys

    I want some way that the value of n can be displayed, just for me reference.

    Cheers

    Attach the expression to a text layer or yet another Expression Control that references a value. With standard parameters such a scale, rotate etc. you also can temporaily use their values as feedback (not that it is always that useful, since obviously it does not show the effect as it is intended). There is no other way. Unfortunately AE does not provide alert() or similar stuff for expressions.
