HisokaMarkers

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.
