In-game type /announce-reload to hot reload the config and start the plugin

Note: Example message templates are automatically created on first launch. You can customize them or create your own message files.

Configuration

After first launch, configuration files will be created in your mods folder. The plugin uses a two-tier configuration system:

AnnouncementConfig.json: Main configuration with timing and ordering settings
messages/: Individual message configuration files

Main Configuration File (AnnouncementConfig.json)

The main configuration file is located at Jemsire_JemAnnouncements/AnnouncementConfig.json:

{
  "IntervalSeconds": 300,
  "EnableRandomization": false,
  "CreateExampleMessages": true,
  "LogLevel": "INFO",
  "Version": 1
}

Configuration Options:

IntervalSeconds: Time in seconds between announcements (default: 300 = 5 minutes)
EnableRandomization: Set to true for random message order, false for sequential order (default: false)
CreateExampleMessages: If set to true, the plugin will automatically create example message files if none exist (default: true).
LogLevel: Controls the detail of plugin logs in the console.
- "INFO" (Default): Shows standard plugin information and errors.
- "DEBUG": Shows detailed internal tracing, useful for troubleshooting message parsing and delivery.
- "NONE": Disables all logs except for critical errors.
Version: Configuration version (currently 1)

Message Configuration Files

Each announcement message has its own configuration file in Jemsire_JemAnnouncements/messages/. The plugin recursively scans this folder, allowing you to organize your messages into subfolders if desired.

Example templates are automatically created on first launch in the messages/example/ subfolder:

example/example.json - Complete example with all message types
example/example-chat.json - Chat messages only
example/example-notification.json - Action bar notification only
example/example-title.json - Title message only
example/example-sound.json - Sound effect only
example/example-all.json - All message types combined
example/example-no-center.json - Example without message centering

Formatting Support

The plugin supports TinyMsg tags, legacy & color codes, and centering offsets.

TinyMsg tags (HTML-like):

Tag	Aliases	Example	Description
`<color:X>`	`<c:X>`, `<colour:X>`	`<color:red>text</color>`	Named or hex color
`<gradient:X:Y>`	`<grnt:X:Y>`	`<gradient:gold:red>text</gradient>`	Color gradient
`<bold>`	`<b>`	`<b>text</b>`	Bold
`<italic>`	`<i>`, `<em>`	`<i>text</i>`	Italic
`<underline>`	`<u>`	`<u>text</u>`	Underline
`<monospace>`	`<mono>`	`<mono>text</mono>`	Monospace
`<link:URL>`	`<url:URL>`	`<link:https://example.com>click</link>`	Clickable link
`<reset>`	`<r>`	`<b>bold<reset>normal`	Reset formatting

Named colors: black, dark_blue, dark_green, dark_aqua, dark_red, dark_purple, gold, gray, dark_gray, blue, green, aqua, red, light_purple, yellow, white

Minecraft-style legacy tags: Use <0>–<9> and <a>, <b>, <d>, <e>, <f> for the same colors as &0–&f (e.g. <e>yellow</e>, <6>gold</6>). Use <red> or <color:red> for red so <c:#FF0000> still works for hex.

Hex colors: <color:#FF0000>red</color> or <c:#FF00FF>magenta</color>

Legacy & color codes (converted to TinyMsg before parsing):

&0–&f – Colors (e.g. &a green, &c red)
&l bold, &o italic, &n underline, &r reset
&#RRGGBB and &x&R&R&G&G&B&B – Hex colors

Centering offset (one per line when Center is enabled):

<offset:N> – Adjust leading spaces: positive = shift right, negative = shift left (e.g. <offset:-2>, <offset:5>). The tag is stripped and not shown.

Note: Legacy & codes are converted to TinyMsg tags before parsing. You can mix tags and & codes in the same message.
