Custom bossbars generally do not follow the expected rules of MCMETA files. For example, changing the “type“ to “nine_slice“ and setting up parameters for the borders will do nothing but squeeze the border size within the 5 pixel tall bossbar and delete everything else.
PROCESS:
1 - Download attacked zip pack.
2 - Make a bossbar in game using one of any color. (Each have a unique border set. White is set to stretch)
3 - Notice it does not react as expected. (White is the only one that shows the full sprite but it displays as horribly disfigured)
EXPECTED RESULT:
The image showing a proper bossbar.
ACTUAL RESULT:
The image showing some odd snippets of a bossbar.
Maybe the bossbar canvas is supposed to only be within the 182 x 5 field, which if so could be a nice feature request with the waypoint styles being added.
Please attach a pack that can be used to reproduce the issue
