🛒 NoCartExplosions

NoCartExplosions is a lightweight, zero-lag server plugin designed to stop TNT Minecarts from destroying blocks and terrain upon detonation while leaving Paper's default explosion damage to players, mobs, and items completely untouched.

---

[!IMPORTANT] Protect your builds without breaking combat or redstone contraptions!
When a TNT Minecart detonates, 0 blocks are broken, but surrounding players and mobs take standard, vanilla-accurate explosion damage.

✨ Features

• 🛡️ Complete Block & Terrain Protection: Prevents TNT Minecarts from damaging blocks, breaking redstone, or cratering land.
• 💥 Preserves Paper Combat Mechanics: Entities (players, mobs, vehicles) still receive standard Paper explosion damage.
• ⚡ Ultra Lightweight & Performant: Event-driven Bukkit listener with minimal CPU footprint and zero tick loss.
• 🌍 World Whitelisting: Restrict protection to specific worlds (e.g., survival, hub) or enable it server-wide.
• 🔄 Live Hot-Reload: Update settings on the fly with /nce reload without restarting your server.
• ☕ Modern Java 21 - 25: Built natively against Paper API 1.21.11 for peak performance.

⚙️ Configuration (config.yml)

The default config.yml is simple and ready to use right out of the box:

# ======================================================
#             NoCartExplosions Configuration
# ======================================================

# Toggle terrain protection for TNT Minecarts / Explosive Minecarts.
# When true, cart explosions will NOT break any blocks or alter terrain.
prevent-terrain-damage: true

# List of world names where cart terrain protection is active.
# Leave empty [] to enable protection across ALL worlds on the server.
# Example:
