using UnityEngine;

public class OnInspectorGUIAttributeExample : MonoBehaviour
{

    [OnInspectorGUI("DrawPreview", append: true)]
    public Texture2D Texture;
    private void DrawPreview()
    {
        if (this.Texture == null) return;

        GUILayout.BeginVertical(GUI.skin.box);
        GUILayout.Label(this.Texture);
        GUILayout.EndVertical();
    }

        UnityEditor.EditorGUILayout.HelpBox("OnInspectorGUI還可以用于方法和屬性", UnityEditor.MessageType.Info);
    }
}
