[游戏开发]Unity 通过脚本名字添加Component

1、游戏运行的时候通过类名挂载脚本

Type type = Type.GetType(scriptName);
var common = gameObject.AddComponent(type);

Type type = Type.GetType("HeadCom");
var aa = gameObject.AddComponent(type);
aa = (UIComponentBase)aa;//将脚本强转, Head2Com继承自UIComponentBase

2、编辑器下可以通过类名挂载脚本

 		string scriptName = "xxxCom";
        Debug.Log(scriptName);

        var assemblies = AppDomain.CurrentDomain.GetAssemblies();
        var defaultAssembly = assemblies.First(assembly => assembly.GetName().Name == "Assembly-CSharp");

		//string nameSpaceName = "xxxCom";
        //var type = defaultAssembly.GetType(nameSpaceName + "." + scriptName);//可以判断是否需要命名空间
        
        var type = defaultAssembly.GetType(scriptName);
        if (type == null)
        {
            Debug.Log("添加失败" + scriptName);
            return;
        }

        var scriptComponent = obj.GetComponent(type);
        if (!scriptComponent)
        {
            scriptComponent = obj.AddComponent(type);
        }
        Debug.Log("完成添加" + scriptName);
