Client-side marker mod inspired by team ping systems from tactical
shooters. Middle-click anywhere you're looking (up to 500 blocks
away) and a colored beam appears at that spot — visible through
walls — with your name and live distance floating above it. Friends
receive the marker over regular /msg, so no server plugin needed.
Features
- See-through-walls beam. Uses the vanilla glow-outline framebuffer
pass on a
BlockDisplay— no shaders, no custom RenderType, plays nice with any resource pack. - HUD label shows sender's name, sender's skin face icon, distance in meters, and (optionally) exact block coordinates.
- Chat-based sync. The mod sends
/msg <friend> [[MRKR:...]]with an encoded payload. The receiver decodes it and draws the beam; the payload itself is hidden from local chat via a client mixin. - Command queue. Whispers go out one at a time with a configurable cooldown, so server antispam doesn't kick you.
- Team-chat mode (second keybind, unbound by default) — a single
/teamchat [[MRKR:...]]reaches the whole team if your server has a team-chat plugin. - Friend list. You only see markers from mutual friends who targeted you. Empty recipients = broadcast to all mutual friends.
- Auto-cleanup. Markers expire after a configurable lifetime, and can optionally remove locally when you stand on the marker block.
- Configurable via ModMenu + Cloth Config: beam color, thickness,
height (from 1 block), text color, render distance, head icon size,
send cooldown, whisper/team command names (
msg,tell,w,pm,teamchat, etc). - Full English and Russian translations.
Controls
Bind the marker keys under Options → Controls → HisokaMarkers.
- Middle mouse (default) — place a marker and send to the first
friend in your list via
/msg. - Team-chat key (unbound) — place a marker and send via
/teamchat.
Config screen: ModMenu → HisokaMarkers.
Requirements
- Minecraft 1.21.11 (Fabric)
- Fabric Loader ≥ 0.19
- Fabric API
- Cloth Config
- ModMenu (suggested — required to open the config screen)
Compatibility
- Client-only. Install on your client. Nothing changes on the server; the payload travels as a normal whisper.
- Doesn't touch vanilla chat. The mod only intercepts messages
containing the
[[MRKR:prefix (your own whisper echoes and incoming team-chat broadcasts). - Creative mode intentionally disables placement — an anti-abuse guard for shared servers.
Under the hood
Payload format: /msg friend [[MRKR:<base64-encoded-marker-data>]]
— a versioned binary blob (~90 bytes pre-base64) carrying position,
color, height, timestamp, and the recipient list. The receiver
decodes it, hides it from chat, and spawns a client-only
Display.BlockDisplay with a glow-outline color.
Notes
The mod doesn't read or modify anything beyond its own payload
messages in the system chat. All beam entities are vanilla
Display.BlockDisplay instances living purely client-side.
