AntiAFKPlus v3.1.1 — Changelog
Bug Fixes
Server idling below 20 TPS even with all modules disabled — Critical
With the plugin enabled, servers dropped to ~17-18 TPS (with low MSPT) and a spark profile showed the server thread parked. It happened regardless of which modules were turned on.

• Root cause: the performance optimizer compared the whole JVM heap usage against a 50 MB budget — always true on a real server — and forced a full System.gc() every 5 seconds. Each forced GC is a stop-the-world pause that breaks tick timing.
• Fix: the periodic forced GC has been removed. Memory cleanup now runs only under genuine heap pressure (used heap above 90% of the JVM max). CPU usage is also measured correctly now, so it no longer triggers spurious internal adjustments. No config change needed.

EssentialsX (and similar AFK plugins) conflict — High
Players typing /afk were immediately unmarked as AFK a few seconds later with the message "X is no longer AFK", even without touching the keyboard or mouse. This still happened on the first 3.1.1 build; it is now fully resolved.

• Root cause: EssentialsX (and any plugin with an AFK teleport feature) processes /afk independently and teleports the player to its own AFK zone. The teleport — and the landing/gravity movement right after it — was counted as real player activity, immediately cancelling the manual AFK state.
• Fix: when a plugin teleports a player who went manually AFK within the last 15 seconds, neither the teleport nor the brief movement that follows it unmarks them. After the 15-second grace period, plugin teleports count as normal activity. No config change needed.
• Recommended config action: Disable EssentialsX's /afk in its config to avoid dual handling:
  
  Code (YAML):

  # EssentialsX config.yml
  disabled-commands :
   - afk
  Then configure teleportation in AntiAFKPlus instead (afk-action.type: TELEPORT or zone-management).

Door spam-click bypass — Critical
Repeatedly right-clicking a door (manually or via auto-clicker / Minecraft accessibility toggle) reset the AFK timer indefinitely. Noteblock, gate, and lever were correctly detected; the door was the sole exception.

Two concurrent bugs:

• Face alternation: a door's clickable face changes when it opens (panel rotates 90°). The passive-repeat filter compared faces exactly, so each click was treated as a new action. Fix: doors and trapdoors now use a face-agnostic comparison. Two-tall door clicks are normalized to the bottom half.
• Air clicks through the open door: after the door opens, the auto-click lands on air. Fix: air clicks are suppressed when the player has not moved since the last door toggle. The same suppression applies to clicks on blocks within 2 blocks of the door (the "block behind the open door" scenario) but not beyond, so functional blocks farther away are never affected.

No config change needed.

AFK warning title/subtitle shows wrong countdown — Medium
The title overlay sent during AFK warnings (warning-subtitle-standard) displayed the configured threshold (e.g. 60, 30, 10) instead of the actual seconds remaining, identical to the chat message bug fixed in v3.1. Only the subtitle was affected; the chat message was already corrected.

• Fix: {seconds} in the subtitle now uses secondsRemaining (actual time left). No config change needed.

AFK warnings not reset after world change — Low
Players who received AFK warnings before switching to a disabled or non-enabled world still had those warnings recorded. On returning to a monitored world, the same warnings never fired again for that session.

• Fix: pending warnings are cleared whenever a player enters a disabled or non-enabled world, regardless of whether they were already marked AFK. No config change needed.

Blank lines in chat when language messages are set to "" — Medium
Setting Bedrock-related messages to "" in the language file (bedrock-detected, bedrock-tip-mobile, bedrock-tip-console, bedrock-tip-desktop) caused a blank chat line for Bedrock players on join instead of silence.

• Fix: all Bedrock welcome and tip messages now check for null/empty before sending. Setting any of these keys to "" correctly suppresses the message. No config change needed.

How to Update

1. Stop the server.
2. Replace the plugin JAR with AntiAFKPlus-3.1.1.jar.
3. Start the server — no config changes required unless noted above.
