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.
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.
