Custom Mob Heads

CMI provides the option to drop custom monster heads when you kill an entity. To customize dropped heads check out ~/plugins/CMI/Settings/CustomHeads.yml.

This is defined by percentage amount in general. Like for example, you can have 5% to drop a sheep’s head but only 1% to drop a creeper’s head when killing one. 

  creeper:
    DropChance: 1.0
  sheep:
    DropChance: 5.0

In addition to this, you can define by how much you want to lower the chance for each player after they got the head for this type of mob. This is helpful in preventing exploitation while killing hundreds of mobs to farm heads. Keep in mind that this limitation will reset to the original state after each server restart.

In this example player has 5% to getting a sheep head and after each instance, they got one, the chance to get the next one will go down by 50% from the previous one, so if the initial chance was 5%, the second one will be 2.5%, next 1.25%, then 0.625% and so on.

  sheep:
    DropChance: 5.0
    LowerWithEachDrop: 50.0

You can have as many custom heads as you want. There is no hard limit on this one, though the recommendation would be to keep it in reasonable numbers. To add a new head simply add new text line which would contain a texture string.  You can find custom head texture string at any site which has database set for it. As an example of one: https://minecraft-heads.com/.

Custom head texture line should start with numbers which will define the chance of dropping that head in particular. So you can have some more rare heads than others for the same entity type. Example

    - 100:eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMzI2NTIwODNmMjhlZDFiNjFmOWI5NjVkZjFhYmYwMTBmMjM0NjgxYzIxNDM1OTUxYzY3ZDg4MzY0NzQ5ODIyIn19fQ==

In this case, head has 100% chance to be picked if the random algorithm checks it before others. In case it would have less than 100%, lets say it’s only 10%. Then the algorithm will try to roll “dice” and check if we can pick this head. If not, then it will move to another random head in the list and will try to pick it. So to avoid not dropping a head at all even though the player should, keep at least one head in the list for a particular mob type with 100% chance.

Optionally you can add a custom head custom name by inserting it into texture string. Example:

    - 100:&2Custom Head Name:eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMjZhNDExMmRmMWU0YmNlMmE1ZTI4NDE3ZjNhYWZmNzljZDY2ZTg4NWMzNzI0NTU0MTAyY2VmOGViOCJ9fX0=

In this case, you will have a head with Custom Head Name as an item name. It’s completely optional and if not defined then the default name will be used.

And last option is to define criteria for the particular head. Format should be like c-[criteria1],[criteria2],[criteria3] This can range from simple check if the creature was tamed or not, if the creature is in a particular color or particular villager type. Example:

  creeper:
    DropChance: 2.0
    LowerWithEachDrop: 50.0
    Heads:
    - 100:c-unpowered:eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvZjQyNTQ4MzhjMzNlYTIyN2ZmY2EyMjNkZGRhYWJmZTBiMDIxNWY3MGRhNjQ5ZTk0NDQ3N2Y0NDM3MGNhNjk1MiJ9fX0=
