Triangulate

Triangulate is a lightweight client-side mod that helps you estimate the position of an object or player in Minecraft by recording your coordinates and the direction you’re looking. By taking multiple “samples” from different spots, the mod calculates where the lines intersect and gives you an estimated location.

Use /calc start to begin triangulating, press R to record data points, and /calc stop to end the process. The mod shows a small indicator above your hotbar to ease calculating where players are located while it’s running and outputs clickable coordinates in chat.
