如何在Cocos2d X中制作在线2人游戏? [英] How can I make an online 2 player game in Cocos2d X?

问题描述

我已经制作了一个类似Megaman的平台游戏，希望人们能够彼此联系在一起玩.它必须在Android和Iphone上运行. 我使用的是Cocos2d X，因此很难找到不使用不推荐使用或删除的方法/对象的良好信息.

I've made a platform game like Megaman and want people to be able to connect with eachother to play it together. It must work on Android and Iphone. I'm using Cocos2d X so it's hard to find good information that's not using deprecated or removed methods/objects.

什么是简单的方法并获得足够的fps以使其看起来不错?

What would be a simple way and get enough fps to make it look good?

令人讨厌的是，人们只是否决了这个问题，因为我真的不知道如何更好地指定它.我不知道该如何开始.感谢你们投下赞成票！ :S

edit: It sucks that people just vote down this question, cause I really don't know how to specify it better. I dont know how to get started with this. Thanks for voting down guys! :S

推荐答案

with help of apple game center you can implement multiplayer very early.

for example

#import <Foundation/Foundation.h>
#import <GameKit/Gamekit.h>

@interface GCHelper : NSObject<GKMatchmakerViewControllerDelegate, GKMatchDelegate>
{
    BOOL isUserAuthenticated;

    UIViewController *presentingViewController;
    GKMatch *match;
    BOOL matchStarted;

    GKInvite *pendingInvite;
    NSArray *pendingPlayersToInvite;
    NSMutableDictionary *playersDict;

    NSString *MultiplayerID;
    NSData *MultiData;
    NSString *otherPlayerID;

    char AlertMessageBoxNo;

    BOOL isDataRecieved;
}

//variables
