ID

glib.id: : The management of entity IDs allows to identify precisely an entity. Useful for example in the case of a shooting game to know who is shooting at whom.

Check ID

check : Allows to compare the glib.id scores of the entities with the glib.targetId score of the entity having executed the function.

  • The latter receives the tag glib.id.checker.

  • The other entities receive the tag

    • glib.id.upper if their glib.id is higher than the glib.targetId.

    • glib.id.lower if their glib.id is lower than the glib.targetId.

    • glib.id.match if their glib.id is equal to glib.targetId.

Example:

Find the entity (or entities) with ID 3:

# Once
scoreboard players set @s glib.targetId 3
function glib:id/check

# See the result
execute unless entity @e[tag=glib.id.match] run tellraw @a [{"text": "No entity found :'(", "color": "dark_gray"}]
execute as @e[tag=glib.id.match] run tellraw @a ["",{"text":"<"},{"selector":"@s"},{"text":">"},{"text": "Hey! Are you looking for me?", "color": "dark_gray"}]

Check parent ID

check_parent : Compares the glib.parentId scores of the entities with the glib.id.target score of the entity that executed the function.

  • The latter receives the tag glib.parentId.checker.

  • The other entities receive the tag

    • glib.parentId.upper if their score glib.id.parent is higher than the id.targetId

    • glib.parentId.lower if their score glib.id.parent is lower than the id.targetId

    • glib.parentId.match if their score glib.id.parent is equal to the id.targetId

Example:

Find all child entities of Bob:

# Once
execute as @e[name=Bob,limit=1] run scoreboard players operation @s glib.targetId = @s glib.id
function glib:id/check_parent

# See the result
execute unless entity @e[tag=glib.parentId.match] run tellraw @a [{"text": "No entity found :'(", "color": "dark_gray"}]
execute as @e[tag=glib.parentId.match] run tellraw @a ["",{"text":"<"},{"selector":"@s"},{"text":">"},{"text": "Hey! Are you looking for me?", "color": "dark_gray"}]

Get simple unique ID

get_suid : (Simple Unique ID) Allows the entity executing the function to get a glib.id score different from all other entities that have already executed the function.

  • Returns the ID on the glib.id score of the executing entity.

  • Gives the tag glib.id.set and glib.id.type.suid to the entities that have already executed the

function

Example:

Give an ID to all players:

# In a loop to give an ID to the players who connect
execute as @a[tag=!glib.id.set] run function glib:id/get_suid

# See the result
scoreboard objective setdisplay sidebar glib.id

Get chain unique ID

get_cuid : (Chain Unique ID) Allows the entity running the function to get a score glib.id different from all other entities that have already run the function. The difference with get_suid is in the way the scores are assigned.

  • ID scores are assigned dynamically based on the available scores, so that they form a string. So, if there are 5 entities, they will be numbered from 1 to 5, without any “hole”. In order not to break this string, you must also execute the update_cuid function in a loop.

  • Returns the ID on the glib.id score of the executing entity.

  • Give the tag glib.id.set and glib.id.type.cuid to the entities that have already executed the function

Example:

Give an ID to all players:

# In a loop to give an ID to the players who connect
execute as @a[tag=!glib.id.set] run function glib:id/get_cuid

# See the result
scoreboard objective setdisplay sidebar glib.id

Update chain unique ID

update_cuid : Allows to update all the CUID of the entities. Executes globally (the source entity does not matter, executing it multiple times per tick will have no effect)

Example:

Keep the ID string free of holes and duplicates:

# To be executed once at the beginning of each tick
function glib:id/update_cuid

# See the result
scoreboard objective setdisplay sidebar glib.id
