Handles.DotHandleCap

パラメーター

説明

ドットハンドルを描き、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。

Dot Handle Cap in the Scene View.

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

using UnityEngine;

public class DotExample : MonoBehaviour {}

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

using UnityEditor;
using UnityEngine;

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

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