The design of the interface in Minecraft is an important component. Many gameplay elements depend on it. Therefore, the author of the Adventurous Hud texture pack decided to refine it.
After installing this pack in the game, the interface design will change. The bar of hunger, the health bar and the rest will move to the upper corner of the screen in a compact status bar. Due to this, the game will become more attractive.
There is a possibility that on iOS the interface will look more than on screenshots, so do not be surprised.
