About DebugUtils
From ModrinthEnables various debugging features of minecraft
🔎 Debug Utils
Mojang has various debugging tools implemented in minecraft that are removed for the release jar. This mod adds them back which might be useful for various cases. You will need this mod on both the client and the server.
Debugging features include for example: > Entity Pathing: Showing a mobs pathfinding
> Entity Brains: Showing the brain states of mobs
> Entity Goals: Showing a mobs goal tasks
> 1.21.9
As of 1.21.9 the debugging features are no longer stripped for the release jar and can be accessed by the user. The process to do so though involves the use of jvm arguments meaning you cannot change it in game. To accomodate that now this mod allows you to toggle the features in game without restarting it.
How to use
Use the command /debugutils <feature> <on | off> to turn a debugging feature on/off.
To turn all currently active features off use /debugutils off.
If you are on 1.21.9 the command has now been split between debugutils and debugutils_client. debugutils_client toggles all features that do not require data from the server.
