About this project
What does Eye Spy add?
Archived
Eye Spy has been archived so I can stay focused on a smaller amount of mods for now. It was mainly intended to test a server-side library I was working on, and will need a basic full rewrite to bring to modern versions, ideally with Polymer as a backend instead.
Eye Spy
Server-sided ping and rangefinding functionality for the Spyglass, targeting Fabric & Quilt.
Features
All features do not require any installs on the client, and can be configured either in-game via the /eyespy config command by operators, or by changing the config file config/eyespy.json5.
Ping


Players can now ping blocks and entities with the spyglass using a hijacked 'Swap Item with Offhand' keybind. This shows a glowing outline to them and surrounding players, as well as the distance, and optionally the description of the target. They can also double-tap the key to show a flashing red hazard ping.
For more details, see the Wiki Page.
Client Install
If a player installs Eye Spy on their client, then they will gain a dedicated keybind for pinging instead of overriding the 'Swap Item with Offhand' functionality. This is completely optional, and doesn't affect other players.
Rangefinder

When using the spyglass, players now see the distance to the hovered block or entity, along with their names if available.
For more details, see the Wiki Page.
Versions
Currently targeting 1.20.4, 1.20.2, 1.20.1 and 1.19.4. As this mod heavily uses Display Entities, a port to versions before would most likely require a rewrite.
Requirements
Bundles several JackFredLib modules and Server Translation API.
