do you know how to change the coding to make thunder storms happen more often i really need to know how PLEASE HELP

I believe that there is already a mod available which increases the chances of hazardous weather. So, I would suggest that you download that mod and see what the modder did.

[Update:]

I was wrong. It removes hazardous weather:

However, it still might give you some clues as to how to mod thunderstorms.

There are also objects and mods which will start particular types of weather; you might find those helpful.

One more thing: this really belongs in the Create forum, since you're asking about how to mod the game.

Thanks i will have a look :D

Could you please use the Edit button to add things to your existing post, rather than posting over and over? Also, please stop quoting my entire post for each of yours. Since no one has replied between my post and yours, there's really no need for the quote.

I've helped you as much as I am able. If that's not enough, you'll have to be patient until someone else answers. However, I continue to believe that you will have better luck getting answers in the Create forum.

ok thanks

Just as a side note, I believe Simslice had a weather machine that tapped into the weather mechanics before EA fleshed them out and made Seasons. I wasn't going to mention it because A> I don't think it was ever updated to be Seasons-compatible, and B> I'm not sure if it's even available anymore.

But if you can find it, you might be able to get some clues from it as well. (Or you might not. As i said, I don't think it was ever made Seasons compatible.)
