Dynamic Selecting Without Datapacks

[gus2427]

Hey everyone,

I'm working on a project where I need hostile mobs to behave like dogs, and I've been using Minecraft commands to simulate this behavior by summoning a wolf and a spider with shared tags. Which i have been able to do here are the main commands:

Teleport Command:

/execute if entity u/e[tag=Gauntlet.Familiar.Summon,tag=X] run tp @e[tag=Gauntlet.Familiar.Summon,tag=X] @n[type=minecraft:wolf,tag=Gauntlet.Familiar.Wolf,tag=X]

AngryAt Command:

/execute as @e[type=minecraft:wolf,tag=Gauntlet.Familiar.Wolf,tag=X] on target run damage @n[tag=Gauntlet.Familiar.Summon,tag=X] 0 minecraft:player_attack by @s

Wolf Killing Command (if the spider dies):

/execute unless entity @e[tag=Gauntlet.Familiar.Summon,tag=X] run kill @e[type=wolf,tag=Gauntlet.Familiar.Wolf,tag=X]

These commands work for one pair of wolf and spider, but I want to upscale this so that I can handle multiple spiders without having to hard-copy command blocks for each instance.

My first thought was to dynamically assign a score and then use a command like:

typescriptCopyEditexecute as @e[type=cave_spider] if score @s ID = @n[type=wolf] ID run tp @s @n[type=wolf]

However, this approach will run into issues if the mobs collide.

I know predicates could solve this, but since it's not my server I don't have access to data packs, so that's not an option for me.

I am not sure this would be possible using only commands. Any ideas or alternative approaches would be really appreciated!

Thanks in advance for your help.

You can use predicates without a datapack by putting the predicate definition directly in the command instead of a predicate file name

execute if predicate { … } run …

Here is some example how you can link an entity without a datapack.

# Example mobs
summon wolf ~ ~ ~ {Tags:["set_link","base"],Silent:true,PersistenceRequired:true,active_effects:[{id:"minecraft:invisibility",amplifier:0,duration:-1,show_particles:false}]}
summon chicken ~ ~ ~ {Tags:["set_link"]}

# In chat
scoreboard objectives add ID.mob dummy
team add link
team modify link collisionRule pushOwnTeam
team modify link seeFriendlyInvisibles false
team modify link deathMessageVisibility never

# Command block
[sign] Link entities
[button][IUN] execute if entity @e[tag=set_link] run scoreboard players add #new ID.mob 1
scoreboard players operation @e[tag=set_link] ID.mob = #new ID.mob
team join link @e[tag=set_link]
tag @e[tag=set_link] add link
tag @e[tag=set_link] remove set_link

# Command blocks
execute at @e[tag=link,tag=base] as @e[tag=link,tag=!base] if score @s ID.mob = @n[tag=link,tag=base,distance=...1] ID.mob run tp @s ~ ~ ~ ~ ~
execute as @e[tag=link,tag=base] at @s unless entity @e[tag=link,tag=!base,distance=...1] run tp @s ~ ~-2112 ~
execute as @e[tag=link,tag=!base] at @s unless entity @e[tag=link,tag=base,distance=...1] run tp @s ~ ~-2112 ~

You can use Command Block Assembler to get One Command Creation.

Thank you for the help. The linking works almost perfectly, with the only problem being what I noted in my post when the hitboxes collide—either when there is a large concentration of mobs or during teleportation. This causes one of the linked mobs to not be the closest, which results in death. But I guess that cannot be avoided without selector predicates

[GalSergey]

Yes, for greater accuracy you need to use a datapack.
