在Unity开发中有许许多多的UI界面，包含着不同的组件，比如Button、Image等，我们需要按正确的路径找到它们并持有它们，这个步骤在界面十分庞大的时候，会十分繁琐易错。本文介绍的自动生成代码工具就是为了解决这一困境，可以自动获取那些我们想要的组件，一键生成，希望对你有所帮助。
生成代码展示
设计思路
我们要使得对象自动生成代码，无非就是分三步，第一步找到这个对象，第二步记录这个对象身上所有需要生成代码的组件，第三步创建一份文件写入我们记录好的内容。
操作流程
- 制作好我们需要的预制体界面，要获取组件的对象用T_来开头
- 右键界面根节点，点击SpawnUICode(生成UI模板)，会弹出操作窗口
- 点击窗口的选择脚本要生成的模块，会弹出我们预设的模块下拉菜单，选择我们对应的模块，即可将脚本生成在选中的模块下。
源码
弹出窗口代码
class GeneratePathSelectWindow : EditorWindow
{
private string[] path = new string[]
{
"Common",
"Store",
"Role",
"Host",
};
private static GameObject selectGo;
public void ShowWindow(GameObject go)
{
selectGo = go;
EditorWindow.GetWindow(typeof(GeneratePathSelectWindow));
}
void OnGUI()
{
if (GUILayout.Button("选择脚本要生成的模块"))
{
ShowGenericMenu();
}
}
private void ShowGenericMenu()
{
GenericMenu menu = new GenericMenu(); //初始化GenericMenu
for (int i = 0; i < path.Length; i++)
{
menu.AddItem(new GUIContent(path[i]), false, SelectPath, path[i]); //向菜单中添加菜单项
}
menu.ShowAsContext(); //显示菜单
}
void SelectPath(object floderName)
{
string t = floderName.ToString();
Debug.Log("选择路径:" + floderName);
UICodeSpawner.SpawnUICode(selectGo, t);//生成脚本代码
}
}
