just call the functions snow_start() or rain_start() in your main function or where ever you want it to start

thx ... very fun contribution, something that can be used in a lot of games, saves the time of coding it ourselves ...
useful!

Same here darragh, quite usefull
Btw, do you have a nice snow/rain bmap

Cheers

Frazzle

Using a *.tga image didn't seem to work. I used a *.pcx instead.

With this small change, the snow AND the rain worked GREAT!

Thanx for the scripts.

i added this in my online wdl library thx
