This is used to control mob spawning density/probability at different distances. This sort of thing probably exists already but I wrote it just in case I want to add any bizarre extra features.
Useful if you want to turn the monster spawn settings in bukkit.yml way up and have a world that gets more dangerous as you move away from the spawn. It can also be used for animals, to make it more of a challenge to find wolves etc.
All of the variables can be changed. It uses some dodgy logic to decide how mobs can spawn at certain distances, but you'd never really notice this with the random spawn positions anyway. It does allow you to entirely prevent certain types of mobs, or prevent them from spawning closer than a certain distance.
Because this is just a 'proof of concept' designed for the possible future of one server, it doesn't have many other features at all. The only command is '/MobProb reload', to reload the config after changing it. Permission is MobProb.reload.
This is a diagram of the kind of thing you can do. The green zones have no monsters and it gets harder as you move away into the red ones. The bubbles are useful for defining small hard or easy areas in certain places.
I'd like to use this for having one large central city in an RP server, with safe bubbles around various small villages in the increasingly difficult wilderness as you move farther from the hub.
Ask me for source code.
