PES 2017 Snow switcher module for Sider - version 1.0 by juce

This is a very simple example of how a random snow switch can be done: when stadium conditions are determined before the match, the module checks if it is rain and winter, and then switches rain to snow with approximately 50% chance.

requires: Sider 3.4.2


IMPORTANT:
if you use stadium-server by @zlac, then you need to make sure that you put snow-mod.lua above StadiumServer.lua in sider.ini. Like this:

...
lua.module = "snow-mod.lua"
lua.module = "StadiumServer.lua"
...

And to whoever made the original art work: the snow particles and snowed pitch - unfortunately i don't know who that was.
