SMPGuard 1.0.9

Note: Perms for bypassing anticheat are cached for performance, after you deop someone, he have to relogin to update bypass permission. So, when you are op and deop yourself, you will bypass anticheat until relogin.

❓ FAQ ❓
Q1: How do I configure SMPGuard? A: All settings are managed via the config.yml file located in the plugins/SMPGuard/ folder. After making changes, use /smpguard reload or restart your server for them to take effect.

Q2: What's the difference between TPS and MSPT? A: TPS (Ticks Per Second) indicates how many game ticks the server is processing per second (ideally 20). MSPT (Milliseconds Per Tick) measures how long each tick takes to process (ideally 50ms or less). High MSPT usually means low TPS and server lag.

Q3: Can I exclude specific worlds from entity clearing? A: Yes, you can specify worlds to exclude in the anti-lag.entity-despawn-scheduler.worlds-to-exclude-from-clearing section of your config.yml.


Q4: How do I set up custom mob drops? A: Enable custom-drops.enabled in config.yml and then define your custom drops under custom-drops.mob-drops for each EntityType you want to modify. Follow the example format in the config file.
