我为什么需要这个？
基本上我需要将彩色图像变成灰度.包括灰度版本的图像可能是一个解决方案,但在我的情况下空间紧张 - 我不希望我的APK太大.此外,我也想研究一些效果的像素.再次,这是为了使APK更小.
我从CCTexture2D找到了getPixel setPixel和获取图像的像素RGBA,但我想要更简单的东西.
任何帮助表示赞赏.
谢谢!
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
我正在学习cocos2D-x并正在做一些精灵动画.
我的目标是当单击一个按钮时,对象会向左移动一些动画.现在,如果你快速点击多次,动画会立即发生,看起来熊似乎希望而不是走路.
它的解决方案看起来很简单,我应该检查动画是否已经在运行以及是否应该运行新动画.
以下是我的代码的一部分.
CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("AnimBear.plist");
CCSpriteBatchNode* spriteBatchNode = CCSpriteBatchNode::create("AnimBear.png", 8);
this->addChild(spriteBatchNode,10);
CCArray *tempArray = new CCArray();
char buffer[15];
for (int i = 1; i <= 8 ; i++)
{
sprintf(buffer,"bear%i.png", i);
tempArray->addObject(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(buffer));
}
CCAnimation *bearWalkingAnimation = CCAnimation::create(tempArray,0.1f);
startAnimation = CCSprite::createWithSpriteFrameName("bear1.png");
startAnimation->setPosition(ccp (350 , CCDirector::sharedDirector()->getWinSize().height/2 -100));
startAnimation->setScale(0.5f);
startAnimation->setTag(5);
//Animation for bear walking
bearAnimate = CCAnimate::create(bearWalkingAnimation);
这里bearAnimate是一个全局变量,我想知道它是否正在播放动画.
我该怎么做.？
谢谢.
我有一个场景包含很多层(该层包含许多精灵),我如何暂停计划和动作,但随后我可以恢复它们.
我正在尝试使用boost 1-49的序列化库来编译一个Android应用程序.具体来说,这个项目有一些方便的脚本来完成工作:https://github.com/MysticTreeGames/Boost-for-Android
使用gnu-libstdc ++ 4.6为armeabi-v7a构建没有针对官方ndk-r8的问题.
至少,它能够创建libboost_serialization-gcc-mt-1_49.a而不会遇到任何错误.在构建期间抛出了几个警告,'禁止零大小数组'_pad'[-pedantic]','不支持'long long','不允许命名的变量宏',没有什么看起来很严重,但我不知道声称自己是gnu编译器的专家.
构建boost也创建了libboost_wserialization-gcc-mt-1_49.a,这似乎很奇怪,但可能无关紧要.我没有将它包含在我的makefile中.
无论如何,当我现在尝试使用此库编译我的代码时,我收到以下错误:

但是我不理解python中的命令os.system(命令),所以任何人都可以帮我解决这个错误.
我尝试将AdMob广告和GooglePlay IAP集成到干净的(hello world)cocos2d-js 3.5项目中.
偶尔(每5次运行)应用程序崩溃并显示下面的异常.当我集成IAP时,这种行为就开始了.清洁AdMob集成很好(或者至少被认为是).
到目前为止,我只做了Java部分(除主屏幕外没有调用cocos代码).我确实将google-play-services_lib升级到23版.
