Handles.SphereHandleCap

Parameters

Description

Draw a sphere handle. Pass this into handle functions.

On EventType.Layout event, calculates handle distance to mouse and calls HandleUtility.AddControl accordingly.

On EventType.Repaint event, draws the handle shape.

Sphere Handle Cap in the Scene View.

Add the following script to your Assets folder as SphereExample.cs and add the SphereExample component to an object in a scene.

using UnityEngine;

public class SphereExample : MonoBehaviour {}

Add the following script to Assets/Editor as SphereExampleEditor.cs and select the object with the SphereExample component.

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(SphereExample))]
public class SphereExampleEditor : Editor
{
    float size = 1f;

    protected virtual void OnSceneGUI()
    {
        if (Event.current.type == EventType.Repaint)
        {
            Transform transform = ((SphereExample)target).transform;
            Handles.color = Handles.xAxisColor;
            Handles.SphereHandleCap(
                0,
                transform.position + new Vector3(3f, 0f, 0f),
                transform.rotation * Quaternion.LookRotation(Vector3.right),
                size,
                EventType.Repaint
                );
            Handles.color = Handles.yAxisColor;
            Handles.SphereHandleCap(
                0,
                transform.position + new Vector3(0f, 3f, 0f),
                transform.rotation * Quaternion.LookRotation(Vector3.up),
                size,
                EventType.Repaint
                );
            Handles.color = Handles.zAxisColor;
            Handles.SphereHandleCap(
                0,
                transform.position + new Vector3(0f, 0f, 3f),
                transform.rotation * Quaternion.LookRotation(Vector3.forward),
                size,
                EventType.Repaint
                );
        }
