About this project
What does NaNny (Fix NaN Health / Absorption) add?
NaNny
Because some mods can't keep their floats in control.
NaNny is a Minecraft Neo/Forge mod that cleans up after mods that set entities' health and/or absorption to NaN.
This is accomplished by hooking into the following events and cancelling and optionally healing the affected entities:
- LivingAttackEvent
- LivingDamageEvent
- LivingHealEvent
- LivingHurtEvent
NaNny creates a TOML configuration file in world/serverconfig/nanny-server.toml
The configuration file has the following options at present:
- doHeal - Enable setting the health of an entity when NaN is dealt or healed to them (Default true)
- health - Percentage of max health to set the entity to when NaN dealt or healed to them (Default 1.0)
- log - Whether or not to log events that set entities' health to NaN (Default true)
