⚠️ Version Note — Atlas Sprite Icons
Atlas sprite icon features (
[#SpriteName],[#item],[##item], custom placeholder icons, player head sprites) require Minecraft 1.21.9 or newer. Versions targeting 1.21.5 through 1.21.8 do not include these features. All other features are available on all supported versions.
Formatting — Used Everywhere
Every message in ChatMod — broadcasts, MOTD, info files, chat — supports the same rich formatting syntax.
| Syntax | Result |
|---|---|
&a, &b, &c … |
Minecraft colour codes |
&#RRGGBB |
Hex colour codes |
&l &o &n &m &k &r |
Bold, italic, underline, strikethrough, obfuscated, reset |
Text{Hover text} |
Hoverable text with a tooltip |
Text{Hover}<action:run_command,/cmd> |
Hover + click to run a command |
Text{Hover}<action:suggest_command,/cmd> |
Hover + click to suggest a command |
Text{Hover}<action:open_url,https://…> |
Hover + click to open a URL |
Text{Hover}<action:copy_to_clipboard,value> |
Hover + click to copy text |
&+ at line start |
Centre the line in chat |
&= inside a string |
Insert a newline |
%player% %online_players% %time% %date% … |
Built-in placeholders |
| PlaceholderAPI placeholders | Supported when PlaceholderAPI is installed |
📢 Broadcasts
Set up automated cycling messages in chatmod.yml. Every broadcast entry supports four display types.
| Type | Where it appears |
|---|---|
CHAT |
Server chat, all players |
ACTION_BAR |
Above the hotbar |
TITLE |
Centre screen, large text |
BOSSBAR |
Top of screen boss bar |
Action Bar
- Single line stays visible for
duration_seconds(re-sent automatically, vanilla clears it after ~3 s without this). - Add a second line to show subtitle text in the title area alongside the action bar.
- Add more lines to cycle through them in sequence, each held for
duration_seconds.
Title Supports up to 4 lines per set:
- Main title
- Subtitle
- Action bar text (optional)
- Replaces the subtitle while line 3 is active (optional)
Add lines1:, lines2: … to cycle through multiple title screens within one broadcast entry, each displayed for duration_seconds.
Boss Bar
Multiple lines are displayed one after another as separate boss bars, each held for duration_seconds.
Broadcast controls
broadcast_enabled: true
broadcast_interval_seconds: 300
randomize_broadcast: false # true = random order instead of sequential
Per-player-count intervals — automatically adjust the broadcast interval based on online players:
players_5_interval_seconds: 240
players_10_interval_seconds: 180
players_25_interval_seconds: 120
🌅 MOTD
Greet players with a personalized message when they join. Supports all formatting, placeholders, hover and click events, and atlas sprite tokens.
motd_enabled: true
motd_messages:
- lines:
- "&+&bWelcome, %player%!"
- "&7Playtime: &e%playtime% &7Last seen: &e%last_play_time%"
Use /cm testmotd to preview without rejoining.
📄 Custom Info Commands
Create unlimited custom text commands from YAML files — /rules, /help, /discord, /info, or any name you choose. ChatMod registers them as real server commands and supports multiple pages and named sections per file.
Create a new one:
/cm create rules
This generates config/chatmod_info/rules.yml which you edit freely, then /cm reload.
Managing your info commands:
| Command | What it does |
|---|---|
/rules |
Shows page 1 (or section named page1) |
/rules 2 |
Shows page 2 by number |
/rules section_name |
Shows a named section directly |
/rules work |
Toggles the command on or off |
/rules permission |
Toggles permission requirement on or off |
/rules permission set chatmod.rules |
Sets the required permission node |
/rules alias add r |
Adds /r as an alias |
/rules alias remove r |
Removes the alias |
/cm list |
Lists all registered info commands |
Pages can link to each other using click actions, making full multi-section help menus easy to build.
📡 Predefined & Scheduled Broadcasts
Define reusable named broadcasts in predefined_broadcasts.yml and send or schedule them from commands.
/cm bc event_soon — send immediately to all players
/cm bcshow event_soon — preview it yourself first
/cm bclist — see all available broadcasts
/cm time 20m often 5 bc event_soon — send 5 times spread over 20 minutes
/cm time 30m bcnow CHAT Hello everyone! — send ad-hoc text after 30 minutes
Each predefined broadcast supports all four display types (CHAT, ACTION_BAR, TITLE, BOSSBAR), permission gating, and full formatting.
For ad-hoc one-off messages without a predefined entry:
/cm bcnow CHAT &aServer event starting now!
/cm bcnow TITLE &6Event! | &eGet to spawn!
/cm bcnow <player> CHAT &eYou have been selected!
🎨 Atlas Sprite Icons (1.21.9+ only)
Render any Minecraft texture atlas sprite inline in any message — chat, MOTD, broadcasts, info files.
| Syntax | Result |
|---|---|
[#diamond] |
Diamond item sprite |
[#grass_block] |
Grass block sprite |
[#playerhead:Name] |
Named player's head sprite |
[#item] |
Sprite of the item you're holding |
[##item] |
Sprite only, no item name |
[#item:3] |
Sprite of predefined item slot 3 |
Sprite aliases and vanilla texture overrides are configured in sprites.yml. You can remap any token to a custom atlas path — for example, make [#chest] show a christmas chest texture.
Sprites work in every context: chat messages, MOTD, broadcasts, info files, hover tooltips, and as persistent chat colour prefixes.
👤 Player Identity Tokens
Reference any online player as an interactive inline element anywhere ChatMod formatting is supported.
| Syntax | Displays |
|---|---|
[@Name] |
Formatted player name with hover profile and click action |
[#@Name] |
Player head sprite + formatted name |
[##@Name] |
Player head sprite only |
[@%player%] |
Dynamic — resolves to the player viewing the message |
Hover profiles in placeholders.yml let you define different tooltips per permission group. Admins can see UUID, ping, world and balance; regular players see rank and balance. Profiles are selected based on the named player's permissions and support full ChatMod formatting including sprites.
🏷️ Player Tagging & Mentions
Type @PlayerName or PlayerName@ in chat to tag someone. They hear a distinct ping sound and see their name highlighted. Use @everyone or everyone@ to notify the whole server (different sound, separate permission).
Tag formats are configured in placeholders.yml under player_tag_format and everyone_tag_format.
💬 Chat Features
Colour & formatting control — Two separate permissions:
chatmod.chat.color— allows&0–&fand&#RRGGBBhex in chatchatmod.chat.format— allows&l,&o,&n,&m,&k,&rin chat
Grant both, one, or neither independently.
Persistent chat colour — Players set a permanent colour for all their chat messages:
/cm chatcolor aqua
/cm chatcolor #FF5500
/cm chatcolor b ← legacy code shorthand
Admins can set it for other players too with the chatmod.chatcolor.others permission.
Sprite prefixes — Set an atlas sprite as your chat colour prefix (1.21.9+):
/cm chatcolor [#dirt]
/cm chatcolor [#diamond]
/cm chatcolor player ← uses your own player head
Inline item display — Players can show their held item in chat using [item], [#item] (with icon), or [##item] (icon only). Each has its own permission node.
Inline sprite icons — Type [#SpriteName] anywhere in chat to embed a sprite icon. Gated by chatmod.chaticon.
Custom placeholders — Typed shortcuts in chat that expand to formatted, interactive text with hover and click events. Defined in placeholders.yml.
📦 Predefined Items & GUI
Store up to 54 items per page (unlimited pages) as shared references, displayed in chat via [item:N], [#item:N], or [##item:N].
Manage items through a visual chest GUI:
/cm items ← opens page 1
/cm items 2 ← opens page 2
Items are stored with full NBT data so custom names, lore, enchantments, and all other properties are preserved exactly.
🔧 Custom Placeholders
Define your own typed shortcuts in placeholders.yml that players type in chat and ChatMod expands into formatted, interactive output.
custom_placeholders:
spawn:
typed: '[spawn]'
chatmod: '&bSpawn&r'
hover: '&bClick to teleport to spawn.'
icon: grass_block
runcommand: /spawn
Each placeholder supports a display text, hover tooltip, click action (run command / suggest command / open URL), and an optional sprite icon. A permission node can be required to use it.
⚙️ Configuration
All configuration is in YAML files under config/chatmod/. No restart needed — use /cm reload after any edit.
| File | Contains |
|---|---|
chatmod.yml |
MOTD, cycling broadcasts, intervals, randomize |
predefined_broadcasts.yml |
Named reusable broadcast entries |
placeholders.yml |
Item formats, tag formats, hover profiles, custom placeholders |
messages.yml |
All player-facing system messages |
sprites.yml |
Sprite aliases and vanilla texture overrides |
config/chatmod_info/*.yml |
One file per custom info command |
PlaceholderAPI placeholders (e.g. %luckperms:prefix%) are resolved in all contexts when PlaceholderAPI is installed. ChatMod skips the API call when a message contains none, so there is no performance overhead for plain messages.
