With the release of Minecraft 1.6(.1), Mojang has made a big change to the way entity health is handled and stored. Prior to Minecraft 1.6.x, Minecraft used integers for health values which many plugins have grown to rely on. From Minecraft 1.6.x onward, Mojang have switched health over to using floats instead, leaving us in a tough position: we would have to break all plugins expecting integer health. Fortunately, as the name of this thread suggests, we put in many hours trying to figure out a way to avoid just flat out breaking plugins and managed to come up with a solution we think everyone will be really happy with. Through the use of a cool new Maven plugin Wolvereness developed, we are now able to provide a backwards-compatibility layer for this change for plugins. This means that plugins that rely on health being integers will still work until we remove the temporary compatibility mechanism. As a result, all plugins will still function, giving you time to work on a solid update to your plugin instead of having to rush a fix out to your users. We will eventually remove the compatibility layer so you'll still want to update your plugins to use the new double methods as soon as you can. What's going on? Minecraft 1.6.x uses floats for health instead of integers, which means all plugins expecting integer health need to be updated. Luckily, we've managed to come up with a way to support both old (integer) and new (double) health formats until plugin developers are able to update their plugins accordingly. Wait, why doubles and not floats? We've decided to go with double health to provide us with future-proofing against the possibility of a similar change from taking place in the future (from floats to doubles). Although our handling of this problem meant extra work on our part and added complexity within the project's compile process, we still believe that this is the best solution for everyone and are confident you'll feel the same way. We hope that the extra effort we've put into this update makes dealing with Minecraft 1.6.1 easier for you guys, removing the stress of needing to immediately update your plugin to support the change to health.
