Dissolve Effect?

Get help using Construct 2

Post » Tue Oct 29, 2013 5:02 am

Hi recently i was doing some investigation about GLSL and some effects, while i was making my research i found out this interesting effect

(i can't post url lol, this is annoying, just complete the webpage)

youtube.com/watch?v=DceLSyaRnMA&list=PLB316B705AD726DA7&index=6&feature=plpp_video

This is the effect i want to achieve, however i failed to write my own GLSL and trying to make this effect with images.

I preffer to ask the comunity if this effect can be achieved with construct 2 with an animated texture, maybe with a perlin noise it can be possible. I was playing with Chromanin TexGen Plugin Perlin Noise

scirra.com/forum/plugin-chromanin-procedural-texture-generation_topic57975.html

and "source in" to make this effect on a image, but this was... a big fail xD, i just did a Perlin Noise code with this plugin:

ch = new Chromanin(256, 'canvas');
ch.initlayers(256, 256);
ch.perlinNoise(0, 128, 9876543, 256, 150, 8, false);
ch.perlinNoise(1, 128, 5642321, 256, 135, 8, false);
ch.addLayers(0, 1, 4, 0, 1);
ch.writeCanvas();

This is an explanation of this effect i've found on Unity 3D:

wiki.unity3d.com/index.php?title=Dissolve_With_Texture

And a useful webpage explaining how to achieve the Dissolve Effect on OPENGL, (tried to port this code but i don't know anything about GLSL)

Does Anyone knows how to achieve this effect, or something similar? maybe an emulation of this on Construct 2?

PS: Sorry for my bad english, non native english speaker here xD

Edited, here is a quick image of the final effect:

Possibly with a pre rendered animation as a mask.
This is an example with frames of noise with color reduction.newt2013-10-29 05:32:39

Hey thanks alot, after trying and tweaking a little i figured it out myself, i edited the
Capx
Now it runs smooth, but i want to know, how i do if i want to have for example a fade in color like the first video? for example if anyone wants to make an acid effect fade out or a burn effect fade out? this would be helpful. Thanks ^^
