Any way to block default Wither Boss Bar? about barapi HOT 2 CLOSED

There's no way to prevent the vanilla bar from showing I'm afraid. This is all handled client side, so there's very little that can be done.

One possible solution however is to use BarAPI only for players that are too far away from your custom wither mob to see the vanilla bar.

The biggest issue is the need to keep the bar showing only for close-by players. I'm building a MOBA style pvp map and attacking the wither should be something that could be pulled off quietly; but since the entire map sees the bar the minute the thing is attacked, it kind of ruins that whole idea.

May have to come up with some other solution.
