【GFFrameWork】UI框架2-UI界面自动生成模板代码工具

前言

我们写UI界面会发现有这么一些重复步骤，创建UI Prefab，然后创建对应界面的View脚本，然后创建跟UI节点组件绑定属性字段还有一些框架层面的接口方法。虽然有时候写这些代码不需要经过大脑，并且键盘敲的啪啪啪爽的飞起，但其实很浪费时间，笔者就想可以写个自动生成UI模板的工具，就减少了这样重复机械式的代码，也节约了大量的时间，我们程序员应该善于创造工具，让自己变"懒"。

效果

操作

1. 选择菜单Tools->AutoGenUI
   

2. 选择要生成的Prefab界面
   

3. 点击生成，生成想要的一级、二级UI View代码
   

界面Prefab要求

既然是自动生成，那UI肯定要符合一定的规范，这里我们将要生成属性字段的节点名后面加上@组件名

生成后的效果

这里生成的是二级界面，所以继承的是SubWindow，如果是一级界面则继承WindowBase，SubWindow也是继承的WindowBase。

代码

AutoGenUI.CS

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

public class AutoGenUI : EditorWindow
{
    [MenuItem("Tools/AutoGenUI")]
    static void Audo_Gen_UI()
    {
        EditorWindow.GetWindow<AutoGenUI>();
    }

    void OnGUI()
    {
        GUILayout.Label("选择UI节点,自动生成UI脚本,需要生成的组件节点名后面加@组件名");
        if (GUILayout.Button("开始生成父窗口"))
        {
            if (Selection.activeGameObject)
            {
                Debug.Log("开始生成");
                GenUIUtil.GenWindow(Selection.activeGameObject);
                AssetDatabase.Refresh();
                Debug.Log("生成结束");
            }
        }

        if (GUILayout.Button("开始生成子窗口"))
        {
            if(Selection.activeGameObject)
            {
                Debug.Log("开始生成");
                GenUIUtil.GenSubWindow(Selection.activeGameObject);
                AssetDatabase.Refresh();
                Debug.Log("生成结束");
            }
        }

        if (Selection.activeGameObject != null)
        {
            GUILayout.Label(Selection.activeGameObject.name);
        }
    }

    {
        // 当我们选着有改变的时候
        this.Repaint();
