position | Position of the cone. |
rotation | Rotation of the cone. |
size | Size of the cone. |
float Distance from mouse to cone in pixels.
Returns the distance in pixels from the mouse pointer to a cone.
Calculates the screen space distance from the mouse pointer to a cone at given world
space position
with the given rotation
and size
.
Returns zero when mouse pointer is directly over the cone.
Uses the current camera to determine the distance.
using UnityEngine; using UnityEditor;
public class ExampleScript : MonoBehaviour { }
// Displays cone in scene view, and distance from mouse // to the cone. [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 cone in scene Handles.color = Color.yellow; Handles.ConeHandleCap(0, position, rotation, size, Event.current.type); // calculate distance from mouse to cone, and display it var distance = HandleUtility.DistanceToCone(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(); } }
