This is a resource pack which will enable the XP Bar to also be displayed in creative mode. Currently there is no in-game setting for it so the only way to enable it would be to use a resource pack like this one. There are different reasons why it would be useful but in the case of Assassiner 003 he needed it for his new map called “Animakerz”.
Creative Mode (normally the XP bar wouldn’t be visible):
Survival Mode (no difference):
- Download Resources .McPack
- Start Minecraft
- Settings > Global Resources > Activate the pack
