Absolutely will not work :'( I've been working on a class server and this is the last thing I need for balance, and just the base health... It just doesn't change it, no errors at all.

You can tell it to do some clever math so it would heal you for the relative amount, simulating higher health ;)

In reply to my other stuff:

The API is all I need, I was going to add the spout health to the mmoMinecraft plugin - Although I'm looking for a plugin that sets HP above 20 to hook into, as thats the only need for a seperate heatlh bar :P

As for levels, all you need is the permission node. That plugin lets you set an event, state how much XP is given on that event and then how much XP is needed to level. When you go up a level you'd get or lose a permission node - so I could configure it to just give higher permission nodes at certain levels -all you need to do is add the permissions.

Two suggestions:

1. Permission-based health, players with permission node healthcontrol.health.50 would get 50hp, whereas if they had healthcontrol.health.27 they'd have 27 HP. No permission node would default to the default set by the plugin.

2. A REEAAAAALLY simple API which means other devs can just hook it and get the health. I would love to make a mmoInfo addon that displays the health in a nice health bar for spoutcraft users :)

This plugin is already gonna be really useful to us as we want 10x health and damage on the server, but especially that permissions thing to give each race unique amounts of health would be brilliant :P

On a more advanced scale, the permissions system there could be used along something like LevelRestriction to mean by doing something, you can slowly raise your HP cap - I'd be happy to share a config for that if you implimented it :)

EDIT: Just logged in with it and found you can't set it above 20...? That might be worth mentioning in the OP...
