Woah, new replies.
So before I got replies, but after I posted, I did some research. Found two ways. One is the posted method, the other is a PHP script--and I have no idea how to PHP, so that's not happening.
As far as stuff goes... I have uncompressed saves always, I heard that compressed saves contribute to potential save corruption, and decided that it was worth it to have extra filesize. However.... world.dat is more than 500 MEGAbytes. I genned the world with tens of thousands of mega and semimegabeasts, maximum demons, night trolls, and weather types. The file is too huge to open with text editors, it just hangs. If I happen to have a php script, how exactly would I go about compiling and executing it? Like.... I don't even know why the script would be written in PHP of all things. It's a fucking WEBSCRIPT, it's not intended to be ran to do things locally. Seriously. If it was Python I would at least understand the logic there--not that I can use python any better but at least I would know, like, where to run the script from. Jesus grandma.
Also as far as locking guys outside.... well, it was a hunter. He was too focused on hunting the GOD DAMN POLAR BEAR that showed up, and so not only was he not super worth saving but I needed to science both what the cloud did and if we had zombies or reanimation at all. (Confirmed no reanimation, but since he didn't show ANY symptoms from the cloud, it made me worried. Hence, this topic.)
