I'm creating a huge aquarium in my FU base, and would like to include Veilendrex. Making it capturable is trivial through the spawn command, but I'm having trouble removing the boss health bar. I'm able to remove the bar *after* spawning it in with: /entityeval monster.setDamageBar("None") ...but the change is not persistent. I've also been unable to reproduce this with spawn command parameters. So, I decided to create a small mod for our server. My first thought was to make a custom pet collar, which would run monster.setDamageBar("None") in applyCollar. I've got the new item created, and I'm able to apply it to a capture pod, but the boss bar is still showing. Should my change be made somewhere else? Or is there some glaring issue I'm overlooking because I just don't have enough experience with this?
