Glitch Particle Effect Script

[Sunbleached]

Hello! I want to try to create a particle system script with a glitch effect that appears and distorts colors behind it. I saw it several times inworld, and on the market. Does anyone know how this works and how to do it?

Sounds like you'd want to look at the blending parameters. The wiki page has a section on it. And I believe the Particle Laboratory inworld might also have some demos or visual explanations you could study.

I can post an effect here later that inverts the colors behind the particle.

Hello! Thanks very much! It would be just awesome!

Here you go,  just plop this in a prim.

Thank you so much! Its very similar. So what part of the script does all the magic? I mean reverses color behind the particles.

These lines, specifically. I added the constant name as a comment. They're listed in the particle system wiki page.

PSYS_PART_BLEND_FUNC_SOURCE, 4,  // PSYS_PART_BF_ONE_MINUS_DEST_COLOR
                                 // "Scale the RGBA values by the inverted RGBA values of the destination"

PSYS_PART_BLEND_FUNC_DEST, 5,    // PSYS_PART_BF_ONE_MINUS_SOURCE_COLOR
                                 // "Scale the RGBA values by the inverted RGBA values of the particle source."
