Technical Changes from Vanilla Minecraft

  • Entity Activation Range(top)


    • Mobs, animals, and items that are not in water are frozen if you are not within the following amount of blocks from them:
      • Town: 12 blocks for animals; 16 blocks for monsters and villagers
      • Wild: 12 blocks for animals; 18 blocks for monsters and villagers
      • Nether: 12 blocks for animals; 18 blocks for monsters and villagers
      • End: 12 blocks for animals; 18 blocks for monsters and villagers
      • Wastelands: 12 blocks for animals; 18 blocks for monsters and villagers
    • Items in the water are not affected by these ranges, and should still move provided that a chunk in every direction is loaded.
    • Things such as crop growth on farms are not affected by this.
    • Only the X and Z axis are checked. There is no Y axis check, so mobs above and below you are not affected by this.
      • Note: Vanilla Minecraft also has similar logic for monsters at the 32 render distance setting, so movement logic for monsters is essentially unaffected. However, vanilla Minecraft's logic also includes a Y distance. This vanilla logic is planned to be removed, so natural spawn grinders will function better.
    • The following things are immune to the Entity Activation Range:
      • Sheep that are missing wool
      • Animals/mobs that:
        • are aggressive to another entity
        • are on fire
        • are riding in a vehicle
        • are in a vehicle with a passenger
        • are not on the ground
        • have special effects
        • are babies
        • are in love

    Entity Limits(top)


    • SMP Town:
      • You can have up to 100 spawned animals per Residence.
      • There is a limit of 30 armor stands per Residence. If the number of dropped items plus armor stands is equal to or greater than 30, no more armor stands can be placed.
      • There is no limit on other entities, such as paintings and dropped items.
    • Utopia Town:
      • You can have up to 150 spawned animals per Residence.
      • There is a limit of 45 armor stands per Residence. If the number of dropped items plus armor stands is equal to or greater than 45, no more armor stands can be placed.
      • There is no limit on other entities, such as paintings and dropped items.
    • Frontier/Wastelands (All Servers):
      • Measured in a 64 block square radius around you.
      • There is a limit of 250 mobs in this area. This is spread across animals and monsters.
      • There is a limit of 30 armor stands per area in the Frontier/Wastelands. If the number of dropped items plus armor stands is equal to or greater than 30, no more armor stands can be placed.
      • There is no limit on other entities, such as paintings and dropped items.
      • The mobs are not per player. They are per area, meaning another player can put an area up to its cap it they are very close to you.
    • Use the command /entc to see the amount of mobs within your current area.

    View Distance(top)


    • The view distance is the amount of chunks that is sent to your client. On Empire Minecraft servers, there is a cap.
    • Empire Minecraft's view distance cap is currently 6 chunks in the Town and 6 chunks in the Wilderness worlds.

    Mob Spawning Distance(top)


    • In Vanilla Minecraft, mobs can spawn up to 128 blocks away from you.
    • On Empire Minecraft, mobs can spawn up to 64 blocks away from you.

    Mob Spawning Limits & Density Checks(top)


    • In Vanilla Minecraft, the formula to calculate how many mobs can spawn is 70 times amount of chunks available under Mob Spawning Distance (these limits are per player).
    • On EMC, the formula to calculate how many mobs can spawn is the same. However, there is a cap of 90 mobs (this limit is per player).
      • If there are under 90 mobs in the area, it checks that there aren't too many of that same mob in the current area.
        • Mobs are limited to spawning in clusters of two.
        • A cluster size is 20 blocks X/Z, and 16 Y.
        • If there are two monsters within the cluster of where an entity is trying to spawn, the spawn will be cancelled.
      • Natural spawning will continue until every player has 90 monsters in their range.

    Mob Despawning/Autokill(top)


    • Monsters will despawn instantly within 15 seconds if they are further than 64 blocks from a player, in the X/Y/Z axis (the check is a 64x64 square, not a 3D distance),
      • Monsters that have picked up another player's items will not despawn
    • If an area exceeds entity limits by any means (by logic cases that cannot be prevented, such as two players being near each other and loading chunks full of monsters that push them over, or monsters moving into range), the system will automatically kill entities until it is at the limit.
      • Monsters are targeted first before animals/villagers
      • Withers are immune
      • Monsters that have picked up player items are immune

    Mob-Spawning Light Limits(top)


    • Empire Minecraft does not change the light limits that mobs spawn in using custom coding. However, it is suspected that a Spigot bug may cause mobs to spawn in lit up areas.
    • It is possible that chunks have invalid light data, allowing mobs to spawn in lit areas. This is also a bug, but will be eventually fixed by an automated system.

    Mob AI Changes(top)


    • Zombies break doors, even on the normal difficulty.

    Mob Head Changes(top)


    • In vanilla Minecraft, you can obtain a creeper, a skeleton, or a Zombie Head if either of those mobs got killed from a charged creeper attack. On Empire Minecraft, almost every creature has a chance of dropping a head when they are killed. See the Heads wiki page for more information.

    Nametags(top)


    • Players are allowed up to five (5) named mobs per area.
    • You cannot rename a Ghast.

    Bed Changes(top)


    • In Vanilla Minecraft, you can use a bed to set your spawnpoint when you are in the overworld, when it is nighttime, and when there are no hostile mobs around you.
    • On Empire Minecraft, you can right-click a bed anywhere and anytime, and it will set your spawn. Beds do not explode when you try to sleep on them in the Nether or in the End.

    Firework Changes(top)


    • On Empire Minecraft, all Fireworks are infinite, which means when you fire them, Fireworks won't be consumed. This applies to Fireworks launched by all methods.
    • Fireworks in dispensers are limited to one launch every two seconds.

    TNT Changes(top)


    • TNT explosion rates are changed so that around 4-8 TNT is allowed to explode per second.
    • TNT doesn't explode special blocks in the Frontier and in the Wastelands; only common blocks like dirt, stone, sand, and soulsand are destroyed.
    • Dispensers can no longer activate TNT.

    Villager Mechanics(top)


    • Chances to unlock a new trade is set to 35% chance instead of the default 20%.
      • There is an additional 15% for every second locked trade.
    • When a trade unlocks, you get an additional five uses before it re-locks again.
    If you are really unlucky and you have gotten three trades locked, every trade will have a 65% chance of unlocking all trades.

    Spawn Egg Mechanics(top)


    • Spawn eggs will not work on Mob spawners.

    Renamed Items(top)


    • Renaming items will make them lose their crafting functionality. For example, if you rename an iron block, you can no longer turn it back into nine iron ingots.

    Blocked Items And Features(top)


    The following items and features have their functionality blocked on Empire Minecraft:
    • Invisibility potions
      • This item can still be created.
    • Fire Charges (this can still be used to craft Fireworks)
      • This item can still be created.
    • Players are no longer able to access the top of the nether (above the bedrock)
    • Skeleton horses cannot be ridden or tamed
    • Entities cannot transfer through Nether or End portals

    Anvil Changes(top)


    • Every repair of an item will increase the repair cost for you. You may sell this item to another player, and they will start from zero on the repair cost.
    • If you get an item back from the player, even if they have repaired it themselves, your original repair cost will still be on the item. Repair history is permanent on an item for everyone who has repaired it, even if a player has changed their username.
    • Repair costs are capped at 39 levels for all items. This eliminates the "too expensive" repair cost on some items if they have been extensively repaired.
    • The formula for repairing items is:
      • REPAIR COST: Vanilla Cost + EMC Personal Repair Cost + 5
      • NEXT PERSONAL REPAIR COST: FLOOR((EMC Personal Repair Cost + ( 3 to 9) * 1.2)
        • 3 levels per raw ingredient used to repair, or 9 levels if combining with another item of same type.
    • Items can be renamed at a cost of one level per item repaired at a cap of 15 levels. That means that renaming three items will cost three levels of experience, while renaming a full stack (64) of items will only cost 15 levels.

    Hopper Changes(top)


    • Items will only fall into hoppers once every three seconds.

    Compass Changes(top)


    In vanilla Minecraft, the Compass will always point to the world's spawn point. However, Empire Minecraft takes it to a whole new level:
    • When teleporting to the wilderness, any Compass you carry with you will automatically point to the outpost you landed on, thus making it easier to find your way back.
    • If you die, the Compass destination will be automatically set to your death point, making it easier to find and retrieve your lost items.

    Combat Changes(top)


    • The Thorns enchantment does not apply to ranged attacks (bow and arrows).
    • Monsters that die without having taken any player damage will not drop XP.
      • If a monster dies when most of the inflicted damage wasn't caused by a player, it will drop a reduced amount of XP.
    • If you set your difficulty to 6 (or higher), the wither can occasionally teleport after being hit.
    • If you set your difficulty to 6 (or higher), Elder Guardians will take 66% less damage when they're out of the water.

    Miscellaneous Changes(top)


    • Item frames will send items directly to a player's inventory instead of dropping them the items to the ground.
    • Item frames will no longer automatically pop off blocks and require player interaction to break.
    • Players will not lose XP upon death anywhere within the Empire.
    • Item despawn times have been increased from 5 minutes to 15 minutes.
    • Inventory items dropped upon death will be protected from pickup for 8 minutes.
      • Players on your friends list (see /fr help) are excluded from the protection.
    • The Wastelands has a limited world size (8000 x 8000).
      • In the Wastelands, there is a 1:1 block travel distance between the overworld and the nether. One traveled block in the nether is equal to one traveled block in the overworld.


    There's a lot that makes up the Empire. Learn a bit about us, how it all works and how to thrive in it.
