Optional Integrations

Optional Integrations

mcMMO works fully standalone. These mods are purely optional — none are bundled, none are declared as dependencies, and mcMMO detects each at runtime and degrades gracefully if it's absent.

Mod	Side	Without it	With it
Mod Menu + Cloth Config	Client	Edit the YAML files by hand.	An in-game settings screen, reachable from the mod list.
Advancement Plaques	Client	Milestones show as normal vanilla advancement toasts.	Milestones show as large animated plaques.

Mod Menu + Cloth Config — in-game config editor

Install both: Cloth Config builds the widgets, Mod Menu provides the entry point. mcMMO then gains a config screen accessible from the mod list.

Versions targeting MC 1.21.11:

Mod	Version
Mod Menu	17.0.0
Cloth Config	21.11.153

What happens with only one of them

Installed	Result
Both	The full editor.
Mod Menu only	The button still works, but opens a small info screen with an Open Config Folder shortcut instead of the editor.
Neither	Nothing is lost. Hand-editing YAML remains the way in and the mod runs identically.

When edits take effect

Edits are written straight back to the YAML on disk — this is a real config editor, not a parallel settings store — and take effect on the next world load, not instantly. Most mcMMO values are read once at load time.

Advancement Plaques — milestone plaques

Advancement Plaques has no API, so there is nothing to hook.

Instead, mcMMO grants hidden vanilla advancements at each milestone, which Advancement Plaques picks up and renders on its own. That means zero dependency in either direction:

• With the mod → you get plaques.
• Without it → you get the ordinary advancement toast.
• The advancements are granted identically either way.

Because they're hidden, they never clutter the vanilla advancement tree.

What fires a plaque

Milestone	Trigger
Round level	A skill crosses a multiple of Level_Interval (default 100).
Rank unlock	Any sub-skill of a skill reaches a new rank.
Skill maxed	A skill hits its level cap.
Power tier	Total power level crosses 500 / 1 000 / 2 000 / 3 500 / 5 000 / 10 000.

Configuring or disabling

config.yml:

General:
    Milestone_Advancements:
        Enabled: true
        Level_Interval: 100

Rank unlocks, power-level tiers and maxing a skill always fire their own plaques regardless of Level_Interval — that setting only controls the round-level ones.

Dedicated servers

Both integrations are client-side. Installing them on a server does nothing; installing them on a client connected to a server works normally, because mcMMO's side of both is just "write YAML" and "grant a vanilla advancement".
