Handles.CubeHandleCap

パラメーター

説明

キューブハンドルを描き、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。

Cube Handle Cap in the Scene View.

Add the following script to your Assets folder as CubeExample.cs and add the CubeExample component to an object in the Scene.

using UnityEngine;

public class CubeExample : MonoBehaviour {}

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

using UnityEditor;
using UnityEngine;

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

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