Use flash to create water waves.

After opening it, you can click the mouse on the screen, or press and hold the left mouse button without moving it over the screen. The circle ripple and ripple will appear. It is very beautiful, just like the real water, very beautiful. 1. Set the stage size (256x256 ). 2. Import images to the database. Do not import to the stage. 3. Open the library settings image link. The identifier is surface. Remove the "Import at runtime" check box, and check "export for ActionScript" and "export in the first frame" 4. insert action code in the first frame. VaR damper = new flash. display. bitmapdata (128,128, false, 128); var result = new flash. display. bitmapdata (128,128, false, 128); var result2 = new flash. display. bitmapdata (256,256, false, 128); var source = new flash. display. bitmapdata (128,128, false, 128); var buffer = new flash. display. bitmapdata (128,128, false, 128); var output = new flash. display. bitmapdata (256,256, true, 128); var surfac E = flash. display. bitmapdata. loadbitmap ("surface"); var bounds = new flash. geom. rectangle (0, 0,128,128); var origin = new flash. geom. point (); var matrix = new flash. geom. matrix (); var matrix2 = new flash. geom. matrix (); matrix2.a = matrix2.d = 2; var wave = new flash. filters. convolutionfilter (3, 3, [1, 1, 1, 1, 1, 1, 1], 9, 0); var damp = new flash. geom. colortransform (0, 0, 9.960937e-001, 1, 0, 0, 2, 0); var water = new flash. filters. displacementmapfilter (result2, origin, 4, 4, 48, 48, "Ignore"); attachbitmap (output, 0); var MS = gettimer (); var frame = 0; vaR mousedown = false; onmousedown = function () {mousedown = true ;}; onmouseup = function () {onenterframe (); mousedown = false ;}; onenterframe = function () {If (mousedown) {VaR _ loc2 = _ xmouse/2; VaR _ loc1 = _ ymouse/2; Source. setpixel (_ loc2 + 1, _ loc1, 16777215); source. setpixel (_ loc2-1, _ loc1, 16777215); source. setpixel (_ loc2, _ loc1 + 1, 16777215); source. setpixel (_ loc2, _ loc1-1, 16777215); source. setpixel (_ loc2, _ loc1, 16777215);} // end if result. applyfilter (source, bounds, origin, wave); result. draw (result, matrix, null, "add"); result. draw (buffer, matrix, null, "difference"); result. draw (result, matr IX, damp); result2.draw (result, matrix2, null, true); output. applyfilter (surface, new flash. geom. rectangle (0, 0,256,256), origin, water); buffer = source; Source = result. clone () ;}; 5. Test it. Click flash, and a ripple appears, the effect is very real. This is also the case. apply directly. vaR damper = new flash. display. bitmapdata (128,128, false, 128); var result = new flash. display. bitmapdata (128,128, false, 128); var result2 = new flash. display. bitmapdata (256,256, false, 128); var source = new flash. display. bitmapdata (128,128, false, 128); var buffer = new flash. display. bitmapdata (128,128, false, 128); var output = new flash. display. bitmapdata (256,256, true, 128); var surface = flash. display. bitmapdata. loadbitmap ("Bg1"); var bounds = new flash. geom. rectangle (0, 0,128,128); var origin = new flash. geom. point (); var matrix = new flash. geom. matrix (); var matrix2 = new flash. geom. matrix (); matrix2.a = matrix2.d = 2; var wave = new flash. filters. convolutionfilter (3, 3, [1, 1, 1, 1, 1, 1, 1], 9, 0); var damp = new flash. geom. colortransform (0, 0, 9.960937e-001, 1, 0, 0, 2, 0); var water = new flash. filters. displacementmapfilter (result2, origin, 4, 4, 48, 48, "Ignore"); attachbitmap (output, 0); var MS = gettimer (); var frame = 0; vaR mousedown = false; onmousedown = function () {mousedown = true ;}; onmouseup = function () {onenterframe (); mousedown = false ;}; onenterframe = function () {If (mousedown) {VaR _ loc1 = _ xmouse/2; VaR _ loc2 = _ ymouse/2; source. setpixel (_ loc1 + 1, _ loc2, 16777215); source. setpixel (_ loc1-1, _ loc2, 16777215); source. setpixel (_ loc1, _ loc2 + 1, 16777215); source. setpixel (_ loc1, _ loc2-1, 16777215); source. setpixel (_ loc1, _ loc2, 16777215);} // end if result. applyfilter (source, bounds, origin, wave); result. draw (result, matrix, null, "add"); result. draw (buffer, matrix, null, "difference"); result. draw (result, matrix, damp); result2.draw (result, matrix2, null, true); output. applyfilter (surface, new flash. geom. rectangle (0, 0,256,256), origin, water); buffer = source; Source = result. clone ();};
