O mode Observable

Observable profiles (tile) entities and shows you what's taking up tick time and where. Forge and Fabric compatible. Please report any bugs on the GitHub repository here.

(Note: the default keybind to open profiler GUI is R.)

Current known issues:

  • Results screen is sometimes empty (closing and reopening the GUI fixes it)

FAQ:

  • Why is the mod crashing on startup with a "java.lang.NoClassDefFoundError: kotlin.jvm.<whatever>"?

The mod uses the Kotlin standard library, so please install a mod that provides that, such as Kotlin for Forge or Fabric Language Kotlin.

  • Does this mod need to be installed on the server?

In order to work, yes. Also, players can connect without the mod installed on the client, however they will not be able to use any of its features.

Screenshots here.

Ako nainštalovať Observable

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.20.1–1.21.4 on Fabric, Forge, NeoForge or Quilt automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge, NeoForge or Quilt

    The loader must match the game version of the mod file, for example Minecraft 1.21.4. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file observable-7.4.3.jar (380 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

  4. Launch the loader profile

    Open “Mods” in the main menu: Observable should be in the list.

Minecraft 1.21.4 runs on Java 21: with a different Java version the game may close right after launch.

Is Observable for Forge or Fabric?

Does Observable need other mods?
