Rain or Snow window?

I have been looking for a script that will animate a prim/prims, example: window in a home where it looks like it is either raining or snowing on a click of a prim...it needs to be with multiple prims...All I seem to find are particle snow machines...not what I'm looking for...just a plain glass where there is a script and a rain or snow texture inside and the script telling which one to use by clicking another prim that is linked...i see them around but none are copy/transfer...i dont need the script to be full permed...just copy and transfer...I have my own snow and rain texures....can some one please help me?
Thank You,
Sweetheart

I think llSetTextureAnim() is the function you're looking for - http://lslwiki.net/lslwiki/wakka.php?wakka=llSetTextureAnim

Basically, create a cel animation texture for rain and another for snow... like a cartoon flipbook. That's a single texture with a grid of various stages of precipitation.. which, when sequenced and looped by llSetTextureAnim(), appears to be a falling rain/snow animation.

Once the animation is rolling, your script can toggle between textures on touch... the snowing texture, the raining texture, or a clear texture for when there's no rain/snow.

Please note that if the above is more than you can or want to handle, it's suggested to post to products wanted forum, as this forum is for teaching and learning to script.
