FixLag

FixLag - A Minecraft 1.19+ Anti-Lag Plugin

FixLag is a lightweight yet powerful PaperMC plugin designed to help server administrators reduce lag by periodically removing problematic entities and alerting staff when entity counts exceed predefined thresholds.

📌 Features

✅ Automatic Entity Cleanup

• Removes TNT, Minecarts, Arrows, Snowballs, and Dropped Items every configurable interval (default: 300 seconds).
• Sends warnings at 3 minutes, 1 minute, 30 seconds, and 10 seconds before cleanup.
• Notifies players when cleanup is complete with the total number of removed entities.
• Minecarts with hoppers are ignored to keep farms working

✅ Entity Load Monitoring

• Detects excessive entities and warns players with fixlag.warning permission when any of the following are exceeded:
  • 50+ Villagers
  • 100+ Dropped Items
  • 75+ Primed TNT
  • 10+ Minecarts in one block

✅ Manual Cleanup Command (/fixlag)

• Grants OPs by default the ability to manually trigger entity cleanup.
• Displays a clickable button (&c[Take Action]) in warning messages for fast response.

✅ Fully Configurable

• Adjust cleanup intervals via config.yml.
• Change entity thresholds for warnings.
• Customize permissions (fixlag.warning for alerts, fixlag.command for manual cleanup).

📖 How It Works

1️⃣ FixLag continuously monitors entity counts on the server.
2️⃣ If excessive TNT, Minecarts, Villagers, or Items are detected, staff are notified.
3️⃣ A clickable button (&c[Take Action]) allows instant cleanup using /fixlag.
4️⃣ At set intervals, TNT, Minecarts, and Dropped Items are removed, reducing lag.
