Eye Spy

Image of the mod's icon, showing the highlights and rangefinder.

When using a spyglass, players can ping blocks and entities by pressing the Swap Item With Offhand key, default F. They can also double-tap to show a flashing red warning ping.

When looking through a spyglass, the distance to the target will be shown in a line of text. Additionally, the name of the block or entity hovered will be shown.

New in 1.3.0: Pings now show distance, as well as descriptions (the latter is disabled by default.)
