Editing Target selectors (section)

===Selecting targets by advancements===
{{exclusive|java|section=yes}}

:Filter target selection based on the entity's [[Advancement|advancements]]. This naturally filters out all non-player targets. All advancements are in a single object, with a list of individual advancement IDs between the braces afterward. The values are [[Argument_types#brigadier:bool|true or false]]. For advancements with one criterion, testing for that criterion always gives the same results as testing for the advancement. Cannot duplicate this argument.
:<code>[advancements={<''resource location''>=<bool>}]</code> — Include only players with the specified advancements and values.
:<code>[advancements={<''resource location''>={<criteria>=<bool>}}]</code> — Include only players with the specified advancement's criteria.

:*<code>@a[advancements={story/smelt_iron=true}]</code> — Include only players who have completed the advancement <samp>minecraft:story/smelt_iron</samp>.
:*<code>@a[advancements={story/form_obsidian=false}]</code> — Include only players who haven't completed the advancement <samp>minecraft:story/form_obsidian</samp>.
:*<code>@a[advancements={story/follow_ender_eye=true}]</code> is the same as <code><nowiki>@a[advancements={story/follow_ender_eye={in_stronghold=true}}]</nowiki></code>.
:*<code><nowiki>@a[advancements={adventure/kill_all_mobs={witch=true}}]</nowiki></code> — Include only players who have killed a witch, for the advancement <samp>minecraft:adventure/kill_all_mobs</samp>.
