HUD Compatibility

GroupManager displays real-time group information on the player's HUD through integration with third-party HUD plugins.

Supported HUD Plugins

AutoMultiHud (by Buuz135)

GroupManager uses reflection to detect and integrate with AutoMultiHud. When available, group status is rendered as a HUD panel using the CSS selector #GroupMultiHUD.

MultipleHUD

Alternative HUD provider. GroupManager detects it at startup and uses it if AutoMultiHud is not available.

Detection Order

1. AutoMultiHud is checked first.
2. If not found, MultipleHUD is checked.
3. If neither is found, the HUD feature is silently disabled.

Detection happens once at plugin startup. No configuration is needed.

HUD Content

The group HUD panel displays:

Element	Description
Group title	"Group" header with member count
Leader	Leader name highlighted
Members	All member names with online/offline indicators
Health bars	Real-time health for each member

Technical Details

GroupManager uses InternalMultiHud — a reflection-based adapter that communicates with the HUD plugin without requiring a compile-time dependency. This means:

• No HUD plugin JAR is needed at build time.
• The integration works with any compatible version of the HUD plugin.
• If the HUD plugin API changes, only the reflection adapter needs updating.

CSS Customization

If you're customizing your server's UI, the group HUD element uses:

#GroupMultiHUD {
    /* Your custom styles here */
}

API Control

External plugins can control the HUD per-player:

GroupService api = GroupManagerProvider.get();

// Hide HUD during a match
api.pauseHud(playerUuid);

// Restore HUD after match
api.resumeHud(playerUuid);

This is useful for plugins that have their own HUD during gameplay.
