cocos2d-android - 如何在android cocos2d中存储游戏分数

Question

我使用 android cocos2d 计算游戏项目的分数，在该游戏中完成第一级后进入下一级别，所以我想存储第一级分数并添加下一级分数。我如何将分数存储在 android-cocos2d 中。

使用NSKeyedArchiver类来存储，这里有一个例子:

------------ 写

        // get allowed save paths
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        // string for the default path
NSString *documentsDirectory = [paths objectAtIndex:0];
        // full path plus filename for save game
NSString *gameStatePath = [documentsDirectory stringByAppendingPathComponent:@"gameState.dat"];
        // storage for game state data
NSMutableData *gameData = [NSMutableData data];
        // keyed archiver
NSKeyedArchiver *encoder = [[NSKeyedArchiver alloc] initForWritingWithMutableData:gameData];
        // encode all variables we want to track
                 [encoder encodeObject:[player inventoryDict] forKey:@"playerInventoryDict"];
                 [encoder encodeObject:[player equippedDict] forKey:@"playerEquippedDict"];
                 [encoder encodeInt:[player initialActionPoints] forKey:@"playerInitialActionPoints"];
                 [encoder encodeInt:[player actionPoints] forKey:@"playerActionPoints"];
                 [encoder encodeInt:[player experiencePoints] forKey:@"playerExperiencePoints"];
                 [encoder encodeInt:[player xpNextLevel] forKey:@"playerXPNextLevel"];
                 [encoder encodeBool:[player isThinking] forKey:@"playerIsThinking"];
        // finish, write and release the encoder
[encoder finishEncoding];
[gameData writeToFile:gameStatePath atomically:YES];
[encoder release];

    NSMutableData *gameData = [NSMutableData data];
            // start the decoder
    NSKeyedUnarchiver *decoder = [[NSKeyedUnarchiver alloc] initForReadingWithData:gameData];

            // start with player data
    PlayerEntity *player = [PlayerEntity player];

        // variables from the PlayerEntity Class
player.inventoryDict = (NSDictionary *)[decoder decodeObjectForKey:@"playerInventoryDict"];
player.equippedDict = (NSDictionary *)[decoder decodeObjectForKey:@"playerEquippedDict"];
player.initialActionPoints = [decoder decodeIntForKey:@"playerInitialActionPoints"];
player.actionPoints = [decoder decodeIntForKey:@"playerActionPoints"];
player.experiencePoints = [decoder decodeIntForKey:@"playerExperiencePoints"];
player.xpNextLevel = [decoder decodeIntForKey:@"playerXPNextLevel"];
player.isThinking = [decoder decodeBoolForKey:@"playerIsThinking"];

        // release the decoder
[decoder release];
