cocos2d-x多分布率适配(iphone5、ipad、android)

游戏已经提交app store等待审核了，现在整理下相关资料。先说说分辨率的问题。

cocos2d-x从2.0.4版本已经完美适配了各种分辨率，下面贴下相关代码，

在AppDelegate::applicationDidFinishLaunching(){}里面加这些代码：

// 填充模式
ResolutionPolicy kResolutionNum = kResolutionNoBorder;

if (target == kTargetIpad)
{
// ipad
CCFileUtils::sharedFileUtils()->setResourceDirectory("iphonehd");

// don't enable retina because we don't have ipad hd resource
CCEGLView::sharedOpenGLView()->setDesignResolutionSize(1024, 768, kResolutionNum);
}
else if (target == kTargetIphone)
{
// iphone

// 设计尺寸width、height
float visibleSizeWidth = 960;
float visibleSizeHeight = 640;

// 根据屏幕尺寸与设计尺寸的比，重新定义设计尺寸（参考kResolutionNum来适配）
CCSize winSize = CCDirector::sharedDirector()->getWinSize();
if (winSize.width/winSize.height > visibleSizeWidth/visibleSizeHeight)
{
visibleSizeWidth = visibleSizeHeight * winSize.width/winSize.height;
}
else if (winSize.width/winSize.height < visibleSizeWidth/visibleSizeHeight)
{
visibleSizeHeight = visibleSizeWidth / (winSize.width/winSize.height);
}

CCFileUtils::sharedFileUtils()->setResourceDirectory("iphonehd");
CCSize VisibleSize = CCEGLView::sharedOpenGLView()->getVisibleSize();
CCEGLView::sharedOpenGLView()->setDesignResolutionSize(visibleSizeWidth, visibleSizeHeight, kResolutionNum);
}
else 
{
// android, windows, blackberry, linux or mac
// use 960*640 resources as design resolution size

// 设计尺寸width、height
float visibleSizeWidth = 960;
float visibleSizeHeight = 640;

// 根据屏幕尺寸与设计尺寸的比，重新定义设计尺寸（参考kResolutionNum来适配）
CCSize winSize = CCDirector::sharedDirector()->getWinSize();
if (winSize.width/winSize.height > visibleSizeWidth/visibleSizeHeight)
{
visibleSizeWidth = visibleSizeHeight * winSize.width/winSize.height;
}
else if (winSize.width/winSize.height < visibleSizeWidth/visibleSizeHeight)
{
visibleSizeHeight = visibleSizeWidth / (winSize.width/winSize.height);
}

CCFileUtils::sharedFileUtils()->setResourceDirectory("iphonehd");
CCEGLView::sharedOpenGLView()->setDesignResolutionSize(visibleSizeWidth, visibleSizeHeight, kResolutionNum);
CCFileUtils::sharedFileUtils()->setPopupNotify(false);
}

 

注意：1.适配iphone5时要添加一张启动图片，图片命名为[e-mail]，不然iphone5两边还是黑边。

     2.setDesignResolutionSize()是指设计尺寸，而getWinSize()是窗口尺寸，显示时是把设计尺寸按照设置的填充模式映射到窗口上去。

     3.三种填充模式：kResolutionExactFit（宽高非等比缩放，全填充）、kResolutionNoBorder（宽高等比缩放，部分区域可能被裁减）、kResolutionShowAll（宽高等比缩放，部分区域可能出现黑边），我觉得用kResolutionNoBorder好些。
