Description

Returns the distance in pixels from the mouse pointer to a cube.

using UnityEngine;
using UnityEditor;

public class ExampleScript : MonoBehaviour { }

// Displays cube in scene view, and distance from mouse // to the cube. [CustomEditor(typeof(ExampleScript))] public class ExampleEditor : Editor { public void OnSceneGUI() { var t = target as ExampleScript; var tr = t.transform; var position = tr.position; var rotation = tr.rotation; var size = 1.0f; // draw a cube in scene Handles.color = Color.yellow; Handles.CubeHandleCap(0, position, rotation, size, Event.current.type); // calculate distance from mouse to cube, and display it var distance = HandleUtility.DistanceToCube(position, rotation, size); GUI.color = Color.black; Handles.Label(position, distance.ToString("F0")); // make scene view repaint on mouse move if (Event.current.type == EventType.MouseMove) Event.current.Use(); } }
