+Minetest mod "Better HUD"

+
+
+Using the mod:
+--------------
+
+This mod changes the HUD of Minetest. 
+It improves the apperance of the health and breath bar and adds a more fancy hotbar. Furthermore it adds a 
+costum crosshair, an armor bar (only for 3darmor mod) and a hunger bar. It includes also a mechanic for hunger.
+
+
+You can create a "hud.conf" to costumize the positions of health, hunger, armor and breath bar. Take a look at "hud.conf.example" to get more infos.
+
+!!NOTICE: Keep in mind if running a server with this mod, that the costum position should be displayed correct on every screen size!!
+
+
+Hunger:
+This mod adds hunger to the game. You can disable this by setting "HUD_HUNGER_ENABLE = false" in "hud.conf", or "hud_hunger_enable = false" in minetest.conf. In case of conflict hud.conf configuration is dominant.
+
+Currently supported food:
+- Apples (default)
+- Bread (default)
+- Drawves (beer and such)
+- Mooretrees
+- Simple mobs
+- Animalmaterials (mobf modpack)
+- Fishing
+- Glooptest
+- Bushes
+- Docfarming
+- Farming plus
+- Mtfoods
+
+Example: 1 apple fills up the hunger bar by 1 bread, 1 bread (from farming) 2 breads in bar.
+
+Altough it show 20 hunger points (10 breads) in hunger bar you can fill it up to 30 points. (5 breads not shown then)
