UI pack: Can’t use slideUp/Down or fadeIn/Out within Velocity.RegisterEffect

I’d like to leverage slideUp/Down in my UI transition, but am unable to.

Have tried something like this:

$.Velocity.RegisterEffect("transition.openDrawer", {
    defaultDuration: 800,
    calls: [
        [{ slideDown }, { duration: 1200 }],
        [{ opacity: 1 }, { queue: false }]
    ]
});

As well as:

// line 4
        [slideDown, { duration: 1200 }],

Console output

Uncaught ReferenceError: slideDown is not defined

Is this possible at present?

Many thanks.

Cool, I didn’t know and didn’t expect it to, but good to hear 😃

A lot of the props aren’t passed on - but changing (which will happen) will be a breaking change in the future.
