Handles.CircleHandleCap

파라미터

설명

Draw a circle 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.

Circle Handle Cap in the Scene View.

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

using UnityEngine;

public class CircleExample : MonoBehaviour {}

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

using UnityEditor;
using UnityEngine;

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

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