Special Entries

Enums

Map configuration values directly to Java Enums. The config file will store the .name() of the enum.

public enum Mode {
    PASSIVE,
    AGGRESSIVE,
    NEUTRAL
}

// ... inside config builder
IEnumConfigEntry<Mode> mobMode = builder.defineEnum(
    "ai_mode", 
    Mode.PASSIVE, 
    Mode.class
);

GUI Behavior: Renders as a Cycle Button that cycles through all available Enum constants.

DateTime

Stores a time stamp.

IDateTimeConfigEntry startTime = builder.defineDateTime(
    "event_start", 
    LocalDateTime.now()
);

Format: The file stores the string: "yyyy-MM-dd HH:mm:ss".

Custom Entries

You can create completely custom config types by implementing the IConfigEntry<T> interface and creating a Serializer.

1. Create Entry Class: Extend BaseConfigEntry<T>.
2. Create Serializer: Implement IConfigEntrySerializer<Entry, T>.
   • Implement toNode / fromNode for file I/O.
   • Implement toNetwork / fromNetwork for sync.
3. Register: Register your new IConfigEntryType in the YamlConfigRegistry.
4. GUI: Register a factory in ConfigEntryComponentRegistry to define how it renders in the menu.

(See the testmod source code in the repository for a full example of a custom entry).
