# NullAttributeRemover<\/p>\n
A lightweight Bukkit\/Spigot plugin that scans and removes **broken** or **invalid attribute modifiers** from players to prevent crashes and instability.
\nOriginally created to fix `java.lang.NullPointerException` in corrupted player data.<\/p>\n
## \ud83d\udd0d What It Does<\/p>\n
This plugin scans player attributes for:<\/p>\n
– \u274c `null` or duplicate UUIDs (even across attributes)
\n– \u274c `NaN` or `Infinity` values
\n– \u274c Invalid or missing operations
\n– \u274c `null`, blank, or UUID-looking modifier names
\n– \u274c Fully broken modifiers (null entries)<\/p>\n
If any are found, they\u2019re **removed automatically**.
\nThe scan can be triggered manually or on events like teleport, respawn, world change, etc.<\/p>\n
## \u2699\ufe0f How It Works<\/p>\n
– Checks every attribute on a player (`GENERIC_MAX_HEALTH`, etc.)
\n– Inspects each modifier\u2019s:
\n – UUID validity and uniqueness
\n – Name validity (including if it looks like a UUID)
\n – Value sanity (no `NaN`, `Infinity`, or zero junk)
\n – Operation type
\n– If any part is broken or suspicious, it\u2019s removed
\n– If a modifier\u2019s UUID is reused in multiple places, all duplicates are removed
\n– Optional logs and messages are configurable<\/p>\n
## \ud83d\udd27 Configuration<\/p>\n
“`yaml
\n# config.yml
\nsilent: false # Suppresses player chat messages
\nkickOnFailure: true # Kick player if bad modifiers can\u2019t be removed

\nlog-to-file: true # Save scan logs to plugins\/NullAttributeRemover\/nar.log
\nlogUUIDLikeNames: true # Warn if modifier name looks like a UUID
