A hunger preview mod for Minecraft, working serverside only.

Every player with permission lakotnik.hunger_preview can see how much nutrition will the selected food provide (granted by default).

#Lakotnik Config

# Update rate in ticks.
tick_update_rate=10

# Whether to enable on low hunger (<= 6.0)
# Causes minor problems as client will think it can
# sprint. If you don't care about that, feel free to enable.
enable_on_low_hunger=false

Why can enable_on_low_hunger be problematic? Sprinting is managed on client - if you hold a food item in your hand and not have enough hunger points to sprint, you will still be able to sprint in intervals when your hunger bar is in preview mode.
