Anti-Creep (NoCreeperExplosions)

Anti-Creep (NoCreeperExplosions) is a lightweight, zero-configuration Minecraft server plugin built for Paper, Purpur, and Spigot (1.21+). It stops both standard and charged creepers from destroying blocks and griefing builds, while preserving vanilla mob spawning and combat mechanics.

✨ Features

💥 Anti-Grief Explosion Suppression: Automatically intercepts and cancels creeper explosions to prevent terrain and structure destruction.
⚡ Charged Creeper Coverage: Handles both normal creepers and high-yield supercharged creepers.
⚡ Zero Performance Overhead: Lightweight single-event listener design with negligible memory and CPU impact.
🔌 Plug and Play: No configuration files or complex setup needed—drop it into your plugins folder and it works immediately.

📋 Requirements

Java	21+	JDK / JRE 21 or 25
Server Software	Paper 1.21+	Paper / Purpur 1.21.x
