TOOL: Ruler

Ruler is a tool that measures distance between two chosen points in the editor.

This can be useful in dealing with tasks that need specific distance measurement, for example helping determine the exact distance needed to trigger the despawning of an object once the player gets too far from it.

To access this tool, change tab in main editor window from “Scene” to “Tools”, and choose “Ruler”.

Once the tool is toggled, click on your desired starting point of the measurement in the viewport, and move the mouse to the desired end point of the measurement.

While doing this, the ruler shows the distance between the starting point and the moving end of it, constantly. To fixate the end-point, click again.
