For some maps, Ive wanted it to rain, but theres no option to make it rain.
SNOW : makes it snow. Theres gonna be some small little patches with snow on the ground, when you press trigger on it you get a snowball, (not the item just a white circle). When you throw the snowball it just explodes.
RAIN : makes it rain, theres gonna be puddles on the ground and when you jump on them just makes a little watersplash.
SUNNY : just makes it Sunny.
THUNDER : its the same as rain, but sometimes it just makes thunder.
