AntiAFK v1.2

AntiAFK is a high-performance, lightweight Paper plugin designed to keep your player slots fresh by removing idle users without impacting server TPS.
Features:

• Zero-Lag Detection: Unlike basic plugins, this uses a scheduled "heartbeat" check instead of monitoring every single player movement, saving massive CPU cycles.
• Action Bar Warnings: Warns players via a countdown on their Action Bar when they are about to be kicked.
• Smart Threshold: Set a minimum player count so the plugin only starts kicking people when the server actually has a certain amount of players online.
• Actual Movement Only: Players cannot bypass the check by simply spinning their mouse; they must physically change coordinates.
• Admin Commands: Reload the config on the fly with /antiafk reload.
• Deep Customization: Full color code support (&c) for all messages.

Updated Config:
YAML

# Time in seconds before a player is kicked
afk-timeout-seconds: 300

# When to start showing the countdown warning (in seconds)
warning-seconds: 30

# Only kick players if there are at least this many people online
min-players-to-kick: 1

# Messages (Supports color codes with &)
