Could someone give me a cog that Produces Lightning and plays a Thunder sound? (like in a lightning storm)

There may be a COG here at Massassi for it.

I made an animated lightning MAT some two years ago, which you can find here:

need a little more info.
do you want it to create lightning things like force lightning does, or change a mat some place like Emon was saying using his mat?

Force Lightning. And it needs to Play a Sound when the Lightning strikes. I also need it to be random, like your rain COG.

hmmm...
i dont know if it would be a good idea to have it like the rain cog. the rain cog makes the rain_tpl for every surface, if i did it like that and you had a lot of sky surfaces it would make for a lot of lightning everytime it wanted to strike. if you like that idea or want to try it heres the cog.

it works ok if you only have a few sky surfaces. setup is mostly the same as the rain cog. the sound plays local, meaning it plays everywhere on the level.
but...
if your level isnt too big there are two other choices for makeing less lightning.
---
1- use ghosts to mark lightning places and the lightning would choose one or two of those ghosts at random to make the lightning from.
2- i could make is so you choose some sky surfaces and the lightning would be made randomly around one or two of those surfaces.
---
the the first method would almost be the easiest but the second would save on the thing count.
the second method would also need little more setup because you would have to manually input the surfaces want lightning to come from.
which do you want if any?

This should work fine. I only Have 1 sky texture in this level so that shouldnt be to many. I'll go try it out.
