Features (Visibility)

Below your hunger and health, but above your hotbar sits your experience bar. This usually tracks how many experience points you have collected between levels, but in MyZ, it represents your visibility bar.

Each individual segment of the bar represents one stretch of blocks a MyZ mob can see you from. This distance can be modified in the config.

Every action a player makes is reflected in their visibility bar.

Walking
Running
Jumping
Sneaking
Talking
Standing in grass
Carrying flesh
Wearing a zombie head
Being on fire
Bleeding
Shooting arrows
Eating
Drinking
Throwing snowballs
Activating redstone
Taking damage
The weather
The time of day
Explosions
Landed arrows

All of these effect what a zombie can see. And once a zombie gets an inkling that something is going on, it'll walk over and investigate. If a player wishes to stay alive, they must monitor their visibility bar.
