Many entities are "linked" together in some way. An cat might have an owner, or a snowball might have a thrower, or a zombie might have an aggro target. I propose a way to test and modify these links with commands.
/link <entity1> <linkType> set <entity2>
/link <entity1> <linkType> test [<entity2>]
/link <entity> <linkType> remove
/execute linked <linkType> -> execute
/link <entity1> <linkType> set <entity2>
- entity1: Specifies the entity/entities whose links to other entities are to be modified.
- linkType: The type of link in question. Different kinds of entities support different types of links.
- entity2: The entity to be linked. Must be a single entity.
Sets the entity1's link of type linkType to entity2.
Examples:
/link @e[type=zombie] aggro set @pMake all zombies attack the nearest player.
/link <entity1> <linkType> test [<entity2>]
- entity1: Specifies the entity/entities whose links to other entities are to be tested.
- linkType: The type of link in question. Different kinds of entities support different types of links.
- entity2 (optional): The entity or entities to test for. If left blank, the command tests whether any entity at all is linked.
If entity2 was included, the command's result is the number of entity1s whose linked entity was any of entity2.
If entity2 was not included, the command's result is the number of entity1s who had a linked entity.
Examples:
/link @e[type=arrow] shooter test @e[type=skeleton]Find the number of arrows that were fired by a skeleton.
/link @e[type=item] thrower testFind the number of items that have a thrower (instead of being dropped on death, fired from a dispenser, etc.).
/link <entity> <linkType> remove
- entity: Specifies the entity/entities whose links to other entities are to be removed.
- linkType: The type of link in question. Different kinds of entities support different types of links.
Removes the entity's linkType, if any.
Examples:
/link @e[type=pig] attacking_entity removeCalm any pigs that are panicking after being attacked.
/execute linked <linkType> -> execute
- linkType: The type of link in question. Different kinds of entities support different types of links.
Works much like /execute as <entity> -> execute, except that this allows us to follow links in the execute command.
Examples:
/execute as @e[type=arrow,tag=!mentioned] linked shooter then say I fired an arrow! /scoreboard players tag @e[type=arrow,tag=!mentioned] add mentionedCause every entity that fires an arrow to say "I fired an arrow!" in chat.
