Handles.SphereHandleCap

パラメーター

説明

スフィア(球体) ハンドルを描き、これをハンドル関数に渡します。

EventType.Layout イベントでは、マウスへのハンドルの距離を計算し、それに基づいて HandleUtility.AddControl を呼び出します。

EventType.Repaint イベントでは、ハンドルの形を描画します。

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
                );
        }
    }
