説明

制約のない移動ハンドルを作成します。

This handle can move freely in all directions. Hold down Ctrl (Cmd on macOS) to snap to the grid (see PositioningGameObjects). Hold Ctrl-Shift (Cmd-Shift on macOS) to snap the object to any Collider surface under the mouse pointer.


Free Move handle in the Scene View.

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

using UnityEngine;

[ExecuteInEditMode]
public class FreeMoveHandleExample : MonoBehaviour
{
    public Vector3 targetPosition { get { return m_TargetPosition; } set { m_TargetPosition = value; } }
    [SerializeField]
    private Vector3 m_TargetPosition = new Vector3(1f, 0f, 2f);

    public virtual void Update()
    {
        transform.LookAt(m_TargetPosition);
    }
}

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

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(FreeMoveHandleExample)), CanEditMultipleObjects]
public class FreeMoveHandleExampleEditor : Editor
{
    protected virtual void OnSceneGUI()
    {
        FreeMoveHandleExample example = (FreeMoveHandleExample)target;

        float size = HandleUtility.GetHandleSize(example.targetPosition) * 0.5f;
        Vector3 snap = Vector3.one * 0.5f;

        EditorGUI.BeginChangeCheck();
        Vector3 newTargetPosition = Handles.FreeMoveHandle(example.targetPosition, size, snap, Handles.RectangleHandleCap);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(example, "Change Look At Target Position");
            example.targetPosition = newTargetPosition;
            example.Update();
        }
    }
}
