    Hello!

    I have an question:
    I have an object, which I need to move along one straight line but with different speeds (how world in Super Mario game moves, for example). How can I make slider, which will control the speed of object, but not it position?

    Thank you in advise.

    It will be easier to have the slider represent an offset in the x direction, and have your position expression look like this:

    xOffset = effect(“Slider Control”)(“Slider”);
    value + [xOffset,0]

    Then control the speed by the keyframing the total x offset with the slider.
