So I'm trying to give players a breath bar out of the water. Unfortunately, the Code (Java): .setRemainingAir() method only works when the player is in the water. So I figured I need to use packets. However, looking around on http://wiki.vg/ I can't find anything of relevance, and snooping around on the ProtocolLib page also yielded no results. Any ideas? How can I make a client think it's underwater with packets?
