MethodEntryAttribute 游戏作弊器的通用实现

游戏开发中经常会有作弊器的需求，比如快速增加金币、切换到特定场景等，一般会选择在屏幕中添加按钮，代码会比较杂乱。

运行时日志窗和命令入口 点击命令可以查看当前所有命令列表

利用C#语言特性Attribute，实现自定义的MethodEntryAttribute作为方法入口标记。

MethodEntry的使用，注意参数列表要一致 反射调用代码

using System;
using System.Collections.Generic;
using System.Reflection;

namespace Babybus.Framework
{
    [AttributeUsage(AttributeTargets.Method, Inherited = false)]
    public class MethodEntryAttribute : Attribute
    {
        public string Description { private set; get; }
        public object[] Args { private set; get; }

        public static List<KeyValuePair<MethodEntryAttribute, MethodInfo>> MethodEntrys { private set; get; }

        static MethodEntryAttribute()
        {
            MethodEntrys = GetMethodEntrys();
        }

        public MethodEntryAttribute(string description, params object[] args)
        {
            Description = description;
            Args = args;
        }

        public override string ToString()
        {
            var toString = Description;

            foreach(var arg in Args)
            {
                toString += ", " + arg;
            }

            return toString;
        }

        private static List<KeyValuePair<MethodEntryAttribute, MethodInfo>> GetMethodEntrys()
        {
            var methodEntrys = new List<KeyValuePair<MethodEntryAttribute, MethodInfo>>();

            var assembly = Assembly.GetExecutingAssembly();
            var types = assembly.GetTypes();

            foreach (var type in types)
            {
                var methods = type.GetMethods(BindingFlags.DeclaredOnly | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic);
                foreach (var method in methods)
                {
                    var attributes = method.GetCustomAttributes(typeof(MethodEntryAttribute), false);

                    foreach (var attribute in attributes)
                    {
                        var methodEntryAttribute = attribute as MethodEntryAttribute;

                        methodEntrys.Add(new KeyValuePair<MethodEntryAttribute, MethodInfo>(methodEntryAttribute, method));
                    }
                }
            }

            return methodEntrys;
        }
    }
