Unity编辑器扩展秘籍-利用Editor.finishedDefaultHeaderGUI增加Header功能

利用Editor.finishedDefaultHeaderGUI这个回调可以实现自定义Header菜单

using UnityEditor;
using UnityEngine;

namespace Yaojz
{
    [InitializeOnLoad]
    public static class DefaultHeaderDrawer
    {
        static DefaultHeaderDrawer()
        {
            Editor.finishedDefaultHeaderGUI += OnDefaultHeaderGUI;
        }

        private static void OnDefaultHeaderGUI(Editor editor)
        {
            var go = editor.target as GameObject;
            if(go == null)
            {
                return;
            }
            var ps = go.GetComponent<ParticleSystem>();
            if (ps != null)
            {
                if (GUILayout.Button("Test"))
                {
                    
                }
            }
        }
    }
}
