NBT Tags for Slime in Minecraft (Java Edition 1.10)

This Minecraft tutorial explains the NBT tags (formerly called data tags) that you can use for a slime in Minecraft Java Edition (PC/Mac) 1.10.

TIP: If you are not running Minecraft Java Edition (PC/Mac) 1.10, find NBT tags for slime in another version of Minecraft:

Background

In Minecraft Java Edition 1.10, the entity value for a slime is Slime. The Slime entity has a unique set of data tags that can be used in Minecraft commands such as: /summon, /entitydata, /give, /fill, /setblock, /testfor.

What are NBT tags (formerly called Data Tags)?

NBT tags allow you to set certain properties of an entity (such as Slime). The NBT tag is always surrounded in {} such as {Size:3}. If there is more than one NBT tag used in a game command, the NBT tags are separated by a comma such as {Size:3, CustomName:Bouncer}.

List of NBT Tags

Here is a list of the NBT tags that you can use for Slime in Minecraft Java Edition (PC/Mac) 1.10:

NBT Tag Value (Description)
Size

number (It represents the size of the slime. The higher the number, the larger the slime. If you enter a number too high, your game will glitch and freeze!!)

0 (Baby slime)
1 (Medium slime)
3 (Large slime)
100 (Giant slime)

Example
{Size:3}

TIP: If you have summoned a slime that is too large and your game glitches, type the following /kill command to kill all slimes in your world:

/kill @e[type=Slime]

This will give you back control!! Though you may need to enter this command a few times as the slimes get smaller and smaller.

CustomName

name (The name to assign to the slime. If the name has spaces, you need to surrounded the name value in "".)

Example
{CustomName:Bouncer}
{CustomName:"Monster Slime"}

Health

number (The number of health points the slime has)

Example
{Health:25.0f}

AbsorptionAmount

number (The number of absorption health points the slime has)

Example
{AbsorptionAmount:2.0f}

Invulnerable

0 (The slime will take damage like normal)
1 (The slime will not take any damage from attacks or physical surroundings)

Example
{Invulnerable:1}

PersistenceRequired

0 (The slime will despawn naturally)
1 (The slime won't despawn)

Example
{PersistenceRequired:1}

NoAI

0 (The slime will have artificial intelligence and will move/behave like normal)
1 (The slime will have no artificial intelligence so it will appear motionless)

Example
{NoAI:1}

Silent

0 (The slime will make its usual noises in the game)
1 (The slime will not make any noise in the game)

Example
{Silent:1}

Fire

ticks (The number of game ticks until the slime is no longer on fire - there are 20 ticks in a second)

Example
{Fire:60}

PortalCooldown

ticks (The number of game ticks until the slime can go through a portal again - there are 20 ticks in a second)

Example
{PortalCooldown:120}

Air

ticks (The number of game ticks the slime has air left for)

Example
{Air:120}

ArmorItems

Since a slime does not wear armor, you can use this data tag to list 4 items that you want the slime to drop when it is killed (4 custom drops)

Syntax
ArmorItems:[{Count:1,id:item}, {Count:1,id:item}, {Count:1,id:item}, {Count:1,id:item}]

Example
{ArmorItems:[{Count:3,id:redstone}, {Count:1,id:golden_horse_armor}, {Count:2,id:iron_ingot}, {Count:7,id:gold_ingot}]}

ArmorDropChances

The drop chances for each of the 4 items listed in ArmorItems. A value of 1.0f means 100% chance of the item being dropped when the slime is killed, 0.5f means 50%, 0.2f means 20%, and so on.

Example
{ArmorDropChances:[1.0f,1.0f,1.0f,1.0f]}

UUIDLeast

A number that specifies the right half of the UUID for the slime (use UUIDLeast and UUIDMost to target/find a particular slime in the game)

Example
{UUIDLeast:-6645587150281567948L}

UUIDMost

A number that specifies the left half of the UUID for the slime (use UUIDLeast and UUIDMost to target/find a particular slime in the game)

Example
{UUIDMost:4420078606457655279L}

id

Slime (The entity value used to represent a slime in the EntityTag or Passengers tag)

Example
{id:Slime}

Passengers

The mob that is riding on the slime. Use the entity value for the passenger mob

Example of skeleton as passenger
Passengers:[{id:Skeleton}]

NBT Tag Examples

To summon a baby slime:

/summon Slime ~ ~ ~ {Size:0}

To summon a medium slime:

/summon Slime ~ ~ ~ {Size:1}

To summon a large slime:

/summon Slime ~ ~ ~ {Size:3}

To summon a giant slime:

/summon Slime ~ ~ ~ {Size:100}

To summon a slime that has 4 custom drops (3 redstone, 1 gold horse armor, 2 iron ingot and 7 gold ingot). Use a command block to run this command:

/summon Slime ~ ~1 ~ {ArmorItems:[{Count:3,id:redstone}, {Count:1,id:golden_horse_armor}, {Count:2,id:iron_ingot}, {Count:7,id:gold_ingot}], ArmorDropChances:[1.0f,1.0f,1.0f,1.0f]}

To give the closest player a slime spawn egg in Minecraft Java Edition (PC/Mac) 1.10:

/give @p spawn_egg 1 0 {EntityTag:{id:Slime}}

Target Selectors

Before we finish discussing data tags, let's quickly explore how to use the @e target selector. The @e target selector allows you to target entities in your commands. If you use the type=Slime value, you can target slimes:

@e[type=Slime]

You can also add a radius value to target slimes within a certain radius of blocks (for example, r=5 lets you target slimes within a 5 block radius of where the command is run):

@e[type=Slime,r=5]

Target Selector Examples

To turn all slimes into baby slimes within a 5 block radius:

/entitydata @e[type=Slime,r=5] {Size:0}

To test for all slimes within a 50 block radius:

/testfor @e[type=Slime,r=50]

To summon a lightning bolt at all slimes:

/execute @e[type=Slime] ~ ~ ~ /summon LightningBolt

To kill all slimes:

/kill @e[type=Slime]

Next, learn how to use the game commands in Minecraft.
