explain how unseen hours works

In Project Zomboid, the "Respawn Unseen Hours" setting controls how long an area must remain unseen by any player for zombies to begin respawning there. Here’s a detailed explanation of how it works:

    Definition:
        "Respawn Unseen Hours" is the number of in-game hours that must pass while an area is not seen by any player before zombies can start to respawn in that area.

    Mechanism:
        When a player enters an area, the unseen timer for that area is reset.
        As long as the area is within the player's line of sight or is being actively visited, the unseen timer will not count down.
        Once the player leaves the area and it is no longer within any player's sight, the unseen timer starts counting.

    Timer and Respawn:
        If the area remains unseen for the duration specified by "Respawn Unseen Hours," zombies will begin to respawn in that area.
        For example, if "Respawn Unseen Hours" is set to 384 hours, the area must remain unseen for 384 in-game hours (16 in-game days) before zombies respawn.

    Example Calculation:
        Assume you have "Respawn Unseen Hours" set to 384 hours.
        In Project Zomboid, 1 in-game day equals 24 in-game hours.
        Therefore, 384 hours divided by 24 hours per day equals 16 in-game days.
        If the game's time scale is set such that each in-game day lasts 3 real-life hours, then 16 in-game days would be 48 real-life hours (16 days * 3 hours per day = 48 hours).

    Resetting the Timer:
        Every time a player re-enters the area, the unseen timer resets to zero.
        This means that for zombies to respawn, the area must remain completely unseen by any player for the full duration specified by the setting.

Practical Implications:

    Active Areas: In areas where players are frequently present or passing through, zombies are less likely to respawn because the unseen timer keeps resetting.
    Abandoned Areas: In areas that players avoid or do not visit often, zombies are more likely to respawn once the unseen timer completes its countdown.

Understanding this mechanic helps players manage zombie populations and strategically decide where to establish safe zones or prioritize clearing efforts.
