Zomboid

Zomboid

Zomboid is a survival overhaul for Minecraft 1.12.2 inspired by Project Zomboid. I originally started this mod because I was building a modpack and wanted zombies that acted like a real horde instead of simply spawning around the player or being turned into damage sponges. Since then, it has grown into a larger survival system that also changes how the player handles injuries, food, water, exhaustion, and sleep.

The goal is to make zombies dangerous because of how they gather and react to the world. It is also meant to make surviving an attack more involved. Getting away from the horde is only part of the problem if you are bleeding, exhausted, thirsty, or carrying an injury that still needs treatment.

Zombie hordes

Zombies are managed as a persistent population and can appear in configurable hordes. Different hordes can contain different zombies and can be limited to certain biomes, allowing the kinds of zombies you encounter to change with the area.

Zombies also have a new way of finding the player:

• Zombies need to see or hear you before they can begin chasing you.
• Sneaking, hiding, and breaking line of sight can help you escape.
• A zombie that loses sight of you will search around the last place it saw you.
• Sounds can attract zombies from farther away and cause a horde to move toward the source.
• Alerted zombies can draw the attention of other nearby zombies.
• Zombies can climb, break through obstacles, and use shared navigation made to handle larger groups.
• Several zombie variations are included in the default horde setup.

The intent is not to constantly place zombies next to the player. Hordes exist in the world, react to what is happening around them, and have to be dealt with or avoided.

Health and survival

Zomboid includes its own health and hunger systems instead of relying on Minecraft's normal hearts and food bar. Damage can create injuries on different parts of the body, and those injuries are what cause most of the player's health loss.

The health system currently includes:

• Seventeen body areas with scratches, bites, burns, fractures, deep wounds, bruises, embedded objects, and other injuries.
• Bleeding, pain, wound infection, healing, and bandages that become dirty over time.
• Bandaging, stitching, disinfecting, splinting, cleaning burns, and removing embedded objects.
• A health screen where you can inspect the body, select injuries, and use care items from your inventory. The screen can be opened with H by default.
• Hunger, thirst, calories, nutrition, body weight, endurance, tiredness, sleep debt, illness, and moodles.
• Physical penalties that can affect movement, mining, combat, eating, drinking, and other actions when the player is hurt or exhausted.
• Drinking from water sources, with the risk of becoming sick from unsafe water.

Food is no longer just a few hunger points. Vanilla foods have their own nutrition values, and what you eat or drink feeds into the longer-running health simulation.

Sleep and world time

Sleeping is based on how tired the player is instead of only checking whether it is nighttime. While the player sleeps, time speeds up and the world continues to run rather than instantly skipping to morning. Sleep quality, recent sleep, and long-term sleep loss all affect how well the player rests.

Zomboid also supports a longer day and night cycle, with a full day lasting 60 minutes by default. This is meant to give the survival systems enough time to develop without changing Minecraft's normal tick rate.

Current state

This mod is still in active development and should be treated as a beta. The main zombie, health, injury, food, water, and sleep systems are working together in singleplayer. Moodle artwork is still being made, so moodles are currently shown as text. Dedicated servers, large modpacks, balance, and compatibility with other mods still need more testing.
