[Cocos2d-x] for different devices, select different adaptive Images

When developing mobile devices, we often prepare image resources of different sizes to adapt to devices of different sizes. I will refer to these resources as puqing image resources and HD image resources. So how can we adapt image resources? Next I will use a demo to demonstrate the implementation of this effect. Tool Introduction: IOS developers have a very useful image synthesis tool, which allows multiple png images to synthesize a large resource image, and can also generate two types of general and high-definition resource images, this tool is TextureParker. How to Use TextureParker to generate resource images open the TP tool, then Add Sprites, Add the image resources you want to Add (preferably png images ), then click the AutoSD option-> Cocos2d-x HD/SD-> Apply. Then, check whether HD/is added to the Data file and Texture file paths. If yes, click Publish to export it. Implementation steps: 1. Create a project file and import the HD and SD folders to the Resources of the Project. 2. Add the adaptive code of the image to the applicationDidFinishLaunching method of AppDelegate.

// Image Adaptive TargetPlatform target = getTargetPlatform (); // if it is an iPhone device if (target = kTargetIphone) {CCSize size = CCEGLView: Export dopenglview ()-> getFrameSize (); if (size. width = 480) {CCFileUtils: sharedFileUtils ()-> addSearchPath ("SD/"); CCLog ("");} else {CCFileUtils: sharedFileUtils () -> addSearchPath ("HD/"); CCLog ("HD ");}}

 

3. Call the image Resource Creation wizard in the main view

CCSize size = CCDirector::sharedDirector()->getWinSize();            CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("pic.plist");      CCSpriteFrame * sp1 = CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("alien.png");      CCSprite * sp = CCSprite::createWithSpriteFrame(sp1);      sp->setPosition(CCPointMake(size.width/2, size.height/2+40));      this->addChild(sp);  

 

Test: select a device. For example, choose hardware> device> iPhone and iPone3.5 (inch). Different resource effects of the call are displayed.
