CmdRelay
Automated event engine: execute random commands with weighted chances (%), auto-cooldowns, and dynamic player timers.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
🚀 CmdRelay
CmdRelay is a lightweight and professional event automation engine for Minecraft servers. It allows you to create automated "Event Groups" that execute random commands based on weighted chances and custom intervals.
✨ Key Features
- 🎯 Smart Weight System: Add commands with simple weights or use percentages (e.g.,
99%). The plugin automatically calculates the math for you. - ⏰ Auto-Execution: No manual input needed! Events run on a repeating cycle based on your cooldown settings.
- ⏳ Dynamic Player Commands: Automatically generates commands like
/eventdelay(customizable) so players can check the time remaining until the next event. - 🛡 Permission-Ready: Fully compatible with LuckPerms. Separate access for admins and players.
- ⚡ High Performance: Optimized code using Bukkit Schedulers to ensure your server stays lag-free (Zero TPS impact).
