Do tell! Those fancy scrollers look like black magic to me. This one is even prettier than the Mr. Mega Mind one.

I think you can do it the same way as a standard sinescroll… just with another sinemovement for the x value on screen. 🙂

I wonder if you could do it using a font stored with the X-flip… maybe 8/16 frames is enough, eg: normal letter (left to right), smaller horizontal resize, etc… then X-flip it for half the frames… then your normal sinescroll code just indexes a different frame of the letter according to a sinelist?
Probably would need to be combined with something else to look like it does tho – I’m tempted to take a look with AR 😛

It is just a “normal” sinus scroller but the x-position follows a different curve instead just incrementing x by one on each blitt. Ends of the scroll are masked and the small $dff102 thing in the scroll is done as an intermediate step with blitter before doing the sinus blitting.

ah of course, i was thinking it was a development on MMM’s idea. come to think of it, i actually did do an effect like it here: http://www.pouet.net/prod.php?which=21643.

This one is prettier than mine though.
