資產尺寸cocos2dx應用

Question

按我的知識，使cocos2dx一個應用程序，我需要三套資源的ipad的，ipadhd和iphone

從應用的一個例子，我看到了，爲了支持所有分辨率的設備，資產規模（背景圖像），我的朋友已經使用了：

ipadhd：2272 X 1536

的ipad：1136 X 768

iphone：568 x 384

這些尺寸適用於橫向模式遊戲。 以下是我的問題： 1.爲什麼我們需要這些尺寸？ 2.我正在嘗試製作一款肖像模式遊戲，因爲我採用了相同的資產尺寸（但由於我在肖像模式下工作，我將圖像尺寸設置爲1536 X 2272,768 X 1136和384 X 568）。但是，由於某些原因，BG圖像在模擬器/設備上顯示時會被放大。我在這裏附上屏幕截圖。

原始圖像：

圖像顯示在模擬器起來：

作爲參考，這裏是設置設備分辨率大小和內容的比例因子的代碼：

#define TARGET_DESIGN_RESOLUTION_SIZE DESIGN_RESOLUTION_480X320 

typedef struct tagResource 
{ 
    cocos2d::CCSize size; 
    char directory[100]; 
}Resource; 

static Resource smallResource = { cocos2d::CCSizeMake(320, 480), "iphone" }; 
static Resource mediumResource = { cocos2d::CCSizeMake(768,1024), "iPad" }; 
static Resource largeResource = { cocos2d::CCSizeMake(1536,2048), "ipadhd" }; 

#if (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_480X320) 
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(320, 480); 
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_1024X768) 
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(768,1024); 
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_2048X1536) 
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(1536,2048); 
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_NONE) 
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(320, 480); 
#else 
#error unknown target design resolution! 
#endif 


bool AppDelegate::applicationDidFinishLaunching() { 
// initialize director 
CCDirector* pDirector = CCDirector::sharedDirector(); 
CCEGLView* pEGLView = CCEGLView::sharedOpenGLView(); 

pDirector->setOpenGLView(pEGLView); 

// Set the design resolution 
pEGLView->setDesignResolutionSize(designResolutionSize.width, designResolutionSize.height,kResolutionNoBorder); 
CCSize frameSize = pEGLView->getFrameSize(); 

std::vector<std::string> resDirOrders; 

// if the frame's height is larger than the height of medium resource size, select large resource. 
if (frameSize.width > mediumResource.size.width) 
{ 
    resDirOrders.push_back(largeResource.directory); 
    pDirector->setContentScaleFactor(largeResource.size.width/designResolutionSize.width); 
} 
// if the frame's height is larger than the height of small resource size, select medium resource. 
else if (frameSize.width > smallResource.size.width) 
{ 
    resDirOrders.push_back(mediumResource.directory); 
    pDirector->setContentScaleFactor(mediumResource.size.width/designResolutionSize.width); 

} 
// if the frame's height is smaller than the height of medium resource size, select small resource. 
else 
{ 
    resDirOrders.push_back(smallResource.directory); 
    pDirector->setContentScaleFactor(smallResource.size.width/designResolutionSize.width); 
} 
CCFileUtils::sharedFileUtils()->setSearchPaths(resDirOrders); 

// turn on display FPS 
pDirector->setDisplayStats(false); 

// set FPS. the default value is 1.0/60 if you don't call this 
pDirector->setAnimationInterval(1.0/60); 

// create a scene. it's an autorelease object 
CCScene *pScene = GameLayer::scene(); 

// run 
pDirector->runWithScene(pScene); 

return true; 
}

其實，原因是因爲你的資源（資產）的大小（分解離子）與您設定的設計分辨率不匹配。您的資產具有不同的長寬比，設計分辨率具有不同的長寬比。

我從來沒有真正在我的遊戲中使用contentScaleFactor。如果所有資產規模相同，只需將設計分辨率設置爲資產的相同分辨率即可。如果您使用kResolutionExactFit策略，Cocos2d-x會自動重新縮放到設備屏幕。我想你應該閱讀Detailed explanation of cocos2d-x multi-resolution support。這是一篇寫得很好的文章。
