Frequently asked questions

How do I enable developer commands after installing this mod?
Developer commands are automatically unlocked once the mod is installed—you don't need to toggle anything. Simply open chat and type commands like /debugpath or /debugmobspawning directly into a world or server.
What do the F3 hotkeys do and how do I use them?
The unlocked F3 hotkeys (F3-E, F3-L, F3-U, F3-V, F3-W) open different debug screens and overlays to show information like entity tracking, chunk loading, and performance metrics. Press F3 plus the letter to toggle each screen while in-game.
Can I use /warden_spawn_tracker on a multiplayer server?
Yes, but only if the server has the mod installed. On vanilla servers without the mod, developer commands won't work. Check with your server admin to confirm the mod is active.
What's the difference between /debugmobspawning and /raid?
/debugmobspawning shows you where and why mobs are spawning in real-time, while /raid triggers or manages raid events. Use /debugmobspawning to understand spawn mechanics and /raid to test raid behavior.
