NOT YET 1.8 COMPATIBLE
This plugin allows you to create boss bar announcements that rotate after a configurable amount of time. Color codes are supported. The health of the bar changes based on the current message compared to the total. 1/3 is empty, 2/3 is half, and 3/3 is full. You can also configure it to only show in certain worlds. So, your spawn can show the messages, while in survival it won't. Use /ba to reload the config.
Requires BarAPI and Yamler
TIP: When using non-alphanumeric characters, surround your string in single quote. Also, messages longer than 100-ish characters seem to get clipped, that is a restriction with Minecraft, I can't do anything about it.
EX:
- '&bThis is a message with color codes.'
instead of:
- &bThis is a message with color codes
Todo:
- Allow per world support (will probably have to remove Yamler and use fancy code to do)
