Water ripple beer glass in Flash
I made this simple water ripple effect, water ripples can be made a couple of different ways, but the most easy on of them all is this, its not that flexible, but can be made in less then a minute.
First off we will need to import the image we want to apply this effect to on to the stage, so go to file -> import -> import to stage and locat your image file, I choose a glass of beer.
In the layers panel make a copy of our layer containing the beer glasse, select the top one, and with the free transform tool make the top beer a bit smaller then the one beneath, (and remember to keep it centered).
Now we will need to make our last layer, above the other two, on this layer we will make an layer mask. Start with the rectangle tool and make a shape above the stage, just above the beer. Now delete part of the rectangle shape as shown below.
Select your shape and convert it to a movie clip. Now for all layers make a new key frame in the time line at frame 20, drag our layer mask down below our beer layer, right click in the time line and make a motion tween.
In the layers panel right click the top layer and choose mask. Then your shape should disapear from the stage, and you can test your movie.
