# This controls if a entitys max health is determined by the entity, or by the disguise.
# Wither is 200, a player is 20. With this enabled, a player disguised as a wither will have the boss bar health accurate to the players health.
# Else it will be 1/20 of the boss bar when he is full health.
# Setting this in LivingWatcher overrides both values.

# This here is a option to turn off misc disguises.
# This means you can not have a living entity disguise as a non-living entity.
# This disables the Attributes packet, Non-living entities can still disguise as other non-living

# This is good if performance is extremely in need.
# This is bad to disable unless you are ONLY going to use the disguises for decorations.
# To be honest. This is basically "Disable entity animations". That option is called 'AddEntityAnimations' in the config but unlike that, this is always in effect.
# Animations set by use of the api or through the disguise command are still in effect.

# Movement packets are the biggest cpu hit. These are majorly used to ensure that the disguises facing direction isn't bugged up
