If you’d like to credit me then go ahead, otherwise I don’t really see any need to :) if you were directly copying from it then it might be good to link back to the tutorial, but if it’s just being used as a reference then you can do whichever you like!

The wave reference? you can do a search for sine wave gifs, there are some good ones people have already made which work as animation refs like this and this.

Otherwise you can just take a static wave and animate it going to one side (easier in Photoshop or Flash). If you can’t do either of those, I’ve got one I made up a while ago that people can use :)

Usually I follow the same basics mentioned here with flowing cloth animations, where that kind of flowing/windy animation follows a wave form. I tend to do this by eye, but if it’s a bit hard to wrap your head around, making up a little wave graphic can be helpful.

Here’s a quick example (there’s one frame in there somewhere that’s bugging me…but it’s fine for the example). When I animate these sort of things I keep in mind how the invisible wave looks, and how whatever it is is being pushed. I do a lot of this in my head, so it’s a tad tricky to explain…

This is the animation slowed down, it moves very slowly at the base, moving to quick and tapering at the end as it’s pulled by everything else.

And slowed with a wave added. The wave doesn’t exactly fit…but I’ve just drawn it badly :\ in the case of short animations I tend to have things follow the timing of the wave in a very linear pattern, but it looks nicer with extra frames added to add some easing as it moves up or down. Having it suddenly skip ahead a bit can work well for rougher movement or when multiple things are affecting the movement.

I find with flowing things it’s better to find examples you like and study the frames, it can get kind of abstract when working with shapes more complex than a pointed tube ^^’ but this principle generally carries through with a lot of moving things like capes, leaves and whatnot.

EDIT : If you need a reference wave to help, I’ve added one here!

The physical ones I sell? they’re just printed on a heavy, gloss stock :O I have them done at a printers, so other than that I wouldn’t know if there’s anything else to it ^^’

I wasn’t planning to, I like keeping the cards for the player character ambiguous :)  Might do it one day…but it’d still be a bit ambiguous…probably be the exact same card but with a little more detail on Hawke and in finery instead of armour ^^’
