  • Creating a Slider and changing its range via script

    Posted by Fabian Brugger on May 9, 2023 at 10:18 am

    Is it possible to change a sliders range, like if you right klick the slider and change set the min and max value, when creating it via a script?

    var comp = app.project.activeItem;

    var layers = comp.selectedLayers;

    for (var p = 0; p < layers.length; p++) {

    layers[p].effect.addProperty(“ADBE Slider Control”);

    I don’t think there’s any way to do that. An alternative might be to create a pseudo effect, which would allow you to define the slider range and apply the slider via a .ffx file, but you’d have to define the range when you create the pseudo effect, not when you run the script.

    Thanks for the quick replay, if you ever in vienna austria ill buy you some beers haha

    I worked around it with just using a linear funktion to translate 0 to 100 into 0 to 360.

    sliderValue = effect(“GlobalOffset”)(“Slider”);

    linear(sliderValue, 0, 100, 0, 360)
