Need a water ripple effect

[Ray Beez]

Any of you know where I can get source for a displacement map based water ripple effect? I need it for a project (due monday). Don't have time to learn to do it myself. I can pay a few bucks for it if needed.

Are you looking for something like this?

Admittedly, I've got a graphic hybrid version if you're interested:

Or are you looking for a drop of water hitting a pond causing a ripple type effect? (Which I don't have but probably could do pretty easily)...

PM me if interested. (I won't be able to send it until tonight though)...

[Ray Beez]

Hmmm, yours might do if I start it from zero and increase the amount of ripple, but I'm looking more for one that is circular... Like something touching a calm pond.

[WilloughbyJackson]

Multiple ripples or one ripple for every click?

Either way, I might be able to help you still. (Of course, I won't be in front of a copy of Flash 8 until 5:00 pm EST today)

Let me know if you want me to take a stab at it...

I'm sure if you changed the MC I used to a radial blur, it would get the effect you want.

yeah like iopred said, create a radial gradient movieclip, loop its animation so it seems seamless and on its enterFrame, draw the frame into a bitmapData object which displaces your water movieclip, depening on your setup i'd go with a black -> alpha black gradient and a neutral gray background and choose 1,1 for the colour components, 5-10 for the scaling. I'm sure you could figure out the placement of the filter

PS i don't mean to hijack the thread but could anyone explain the alpha color component in a displacement filter, couldn't get it to work, probably because i didn't understand it

[iopred]

It takes the data from the alpha channel of the source bitmap, whereas the other types use the red/green/blue channel.

alpha wont work if the bitmap isn't a transparent bitmap (obviously).

[mr_malee]

right, so everything that is greater than 00 alpha will not displace?

[Ray Beez]

Thanks all. Willoughby came through like a champ! I will post the results when I've applied it to the actual project.

:-)

No Malee, it works like the other channels. 128 alpha is stationary 0 is full displacement, 255 is full displacement the other way.

Although flash seems to handle alpha in 100 sometimes, and 0-1f sometimes too.
