Editor.HasFrameBounds()

설명

Validates whether custom bounds can be calculated for this editor.

Use this to validate if Editor.OnGetFrameBounds should be called for this window.

using UnityEngine;
using UnityEditor;

// This example traverses all bones in the hierarchy and calculates bounds for the entire object
public class GameObjectEditorWindow: Editor
{
    private bool HasFrameBounds()
    {
        // the result of this function depends on implementation
        // it will most likely be used to evaluate whether bounds
        // can exist for the targets of this Editor Window
        return Selection.objects.Length > 0;
    }

    public Bounds OnGetFrameBounds()
    {
        Transform bone = Selection.activeTransform;
        Bounds bounds = new Bounds(bone.position, new Vector3(0, 0, 0));
        foreach (Transform child in bone)
            bounds.Encapsulate(child.position);

        if (bone.parent) bounds.Encapsulate(bone.parent.position);

        return bounds;
    }
}
