我想用cocos2d-x(c ++)读一个plist这里是我的plist:
<array>
<dict>
<key>x</key>
<integer>0</integer>
<key>y</key>
<integer>0</integer>
</dict>
<dict>
<key>x</key>
<integer>140</integer>
<key>y</key>
<integer>12</integer>
</dict>
<dict>
<key>x</key>
<integer>120</integer>
<key>y</key>
<integer>280</integer>
</dict>
<dict>
<key>x</key>
<integer>40</integer>
<key>y</key>
<integer>364</integer>
</dict>
<array>
它基本上是由(x,y)坐标组成的字典数组.我原来的阅读代码是:
NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"w%i", world] ofType:@"plist"];
NSMutableArray* points = [NSMutableArray arrayWithContentsOfFile:path];
但现在我需要将其翻译成c ++中的cocos2d-x.我用Google搜索了一些文章,但它们都是关于将plist读入字典.我需要一个阵列.
编辑:::
现在我改变了我的plist格式:
<dict>
<key>11x</key>
<integer>0</integer>
<key>11y</key>
<integer>0</integer>
<key>12x</key>
<integer>140</integer>
<key>12y</key>
<integer>12</integer>
<dict>
我该怎么办？？？我仍然得到同样的错误:
CCDictionary<std::string, CCObject*>* dict = CCFileUtils::dictionaryWithContentsOfFile(plistPath);
int x = (int)dict->objectForKey("11x");
int y = (int)dict->objectForKey("11y");
不行.请先试一试.看看你是否可以从样本plist中读取一个int
我的cocos2d-x游戏在进入后台时崩溃了.这是来自AppDelegate的一些代码:
// This function will be called when the app is inactive. When comes a phone call,it's be invoked too
void AppDelegate::applicationDidEnterBackground()
{
CCDirector::sharedDirector()->pause();
CCUserDefault::sharedUserDefault()->flush();
CocosDenshion::SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
}
// this function will be called when the app is active again
void AppDelegate::applicationWillEnterForeground()
{
CCDirector::sharedDirector()->resume();
CocosDenshion::SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
}
和错误消息:
libGPUSupportMercury.dylib`gpus_ReturnNotPermittedKillClient:
0x3797e094: trap
0x3797e096: nop
请注意,iPhone总是崩溃,但Android上99%崩溃(当游戏没有加载大图像时等等)
编辑:我已经尝试过CCDirector :: sharedDirector() - > stopAnimation(),它适用于iOS.但仍然崩溃的Android(不是立即.当返回到应用程序时,屏幕变黑(但我认为它仍然在运行,因为背景音乐仍在播放.然后大约5秒后它崩溃)
编辑2:Eclipse中的错误消息:
libEGL call to OpenGL ES API with no current context (logged once per thread) (red warning text)
libc Fatal signal 11 …我有以下代码.该response.result.value类型是Optional(AnyObject),我要检查
[[String: AnyObject]]如果...返回...声明,我更喜欢一个线卫
Alamofire.request(.GET, API.listArticle).responseJSON {
response in
print(response.result.value)
guard let articles = response.result.value as? [[String: AnyObject]] where articles.count > 0 else {
return
}
for article in articles {
let entity = NSEntityDescription.insertNewObjectForEntityForName("Article", inManagedObjectContext: DBHelper.context()) as! Article
entity.title = article["title"]
entity.content = article["content"]
}
}
错误是article["content"]行,
cannot subscript a value of type Dictionary<String, AnyObject> with an index of type String.
我还需要检查是否title存在article？它会崩溃还是什么都不做？
我试图从头开始构建一个nginx图像(而不是使用官方的nginx图像)
FROM ubuntu
RUN apt-get update
RUN apt-get install -y nginx
RUN rm -v /etc/nginx/nginx.conf
ADD nginx.conf /etc/nginx/
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80
COPY ./files/ /var/www/html/
CMD service nginx start
这是我nginx.conf在当前目录下的文件.
server {
root /var/www/html
location / {
index.html
}
}
我的虚拟index.html文件在./files文件夹下
<p1>hello world</p1>
我运行这个命令
docker build -t hello-world .
和
docker run -p 80:80 hello-world
但是我说错了
* Starting nginx nginx
...fail!
可能是什么问题？
我刚刚完成了我的iPad版本(全部和精简版)我的游戏Let's Spot It.他们使用不同的捆绑种子ID.(就像不同的应用程序)然后我想在其iPhone版本上工作.但我无法找到"生成新的"捆绑种子ID的选项.
Bundle Seed ID (App ID Prefix)
Use your Team ID or select an existing Bundle Seed ID for your App ID.
发生了什么？我没有使用高级技术,比如在我的两个应用之间共享数据.所以我可以使用与其他应用程序相同的应用程序ID(与此应用程序无关),或者我可以只使用团队捆绑种子ID吗？如果我使用团队ID,我应该在我的xcode项目中做什么？
