Set animation origin for individual steps?

[Eric Oliver]

Hey all -

I see how to modify the animation origins for the entire slideshow (core properties originX and originY) but is there a way to set the animation origins for individual steps? That is to say, most steps in my presentation I'd like to have animating with a center-center origin, but a couple need to be center-bottom. I'm attaching an image of what I'm looking to do on an individual step (not on the whole animation).

The reason for wanting the origin this way is that I could create the impression of the circle spinning and items moving above it (rather than everything including the circle moving).

Does that make sense? Any ideas?

Hey Eric,

that's not possible by default, but you can hack it with a bit of javascript.

You can access (and change) the settings with this method: $('#jmpress').jmpress('settings')

So hook setActive and update the originX/Y to your needs.

You additionally need this code to reflect changes of the originX/Y after every slice change (maybe add a transistion too):

	$.jmpress("applyStep", function( step, eventData ) {

		$.jmpress("css", eventData.area, {

			left: eventData.settings.originX,

			top: eventData.settings.originY,

		});
	});

Thanks much - this was helpful. I did realize I was going about this the hard way, though -- was easier to do child steps and handle it that way.
