glitchy effect.

Instead of this being a problem. I was wondering how I could achieve a glitchy effect in a game. Maybe some text starts turning green and an annoying buzzing sound goes off. Understand?

Use some web Gl effects and turn then on or off as needed

you can also do this to an entire family of objects or a layer if you need to

I often use a semi transparent overlay and add severe warp effects for a short duration in conjunction with a screen shake effect
