GM Measure Distances
Game Master only: middle-mouse point-to-point distance tool with a visible line, live preview, and on-world labels.
Overview
Game Master only. GM Measure Distances is a local ruler in the editor/GM view: place two world points under the cursor, see a line and labels, then clear or start over.
How it works (high level)
- Input is wired through the editor manager (e.g. middle mouse on PC, with a controller fallback bound to the same flow). Clicks are rejected when the cursor does not resolve to a usable world hit.
- A singleton measurement service keeps the two points, drives a lightweight overlay (canvas + world-height text), and skips redundant redraws when the camera has not moved enough to matter—purely a performance nicety.
- Third click on a finished segment clears it; the next click begins a new first point.
