Question

我是cocos2dx开发的新手。我几乎在使用cpp语言的android中学习cocos2dx（版本3.3）的所有基本级别。我发现有很多关于cocos2dx.org的更新。

在android我正在使用cocos2dx版本3.3开发俄罗斯方块游戏，我想知道什么是实现真棒动画的最佳方式，如滴答炸弹，炸弹爆炸，旋转游戏分数显示，弹出和消失的气球与游戏分数增量。我想知道在使用c ++的android中动画实现cocos2dx。我们还需要制作支持多屏幕支持的游戏，我搜索过所有这些点都无法在谷歌上找到太多信息。

我很好地展示了初学者级别的声纳系统支持，我们非常感谢，我观看了声纳系统通过YouTube分享的所有视频。我在那边学到很多东西。我想在cocos2dx中知道android中的高级动画。

我们希望得到任何帮助。

谢谢

Answer 1

我也是cocos2dx 3.3的新手。好吧，我使用（.plist）粒子效果使用动画进行爆炸（爆炸）首先你需要一个动画的.plist文件。有一个用于制作.plist文件的在线编辑器。你可以看看这是链接。 http://www.effecthub.com/particle2dx

现在你可以使用这行代码

CCParticleSystemQuad *system = CCParticleSystemQuad::create("explodeEffect.plist");

system->setTexture(CCTextureCache::sharedTextureCache()->addImage("yourplayer.png"));
system->setDuration(0.05);
system->setScale(3.0f);
 system->setPosition(yourplayer->getPosition().x, yourplayer->getPosition().y);
this->addChild(system,1);
system->setAutoRemoveOnFinish(true);

这会对你有所帮助

这是我的appmacros.h filr ..

#ifndef __APPMACROS_H__
#define __APPMACROS_H__

#include "cocos2d.h"



#define DESIGN_RESOLUTION_480X320    0
#define DESIGN_RESOLUTION_480X800    1
#define DESIGN_RESOLUTION_1024X768   2
#define DESIGN_RESOLUTION_1280X800   3
#define DESIGN_RESOLUTION_2048X1536  4

/* If you want to switch design resolution, change next line */
#define TARGET_DESIGN_RESOLUTION_SIZE  DESIGN_RESOLUTION_1280X800

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

static Resource smallResource  =  { CCSizeMake(480, 320),   "iphone" };
static Resource mysmallResource  =  { CCSizeMake(800, 480),   "iphone" };
static Resource mediumResource =  { CCSizeMake(1024, 768),  "ipad"   };
static Resource myResource =  { CCSizeMake(1280, 800),  "ipad" };
static Resource largeResource  =  { CCSizeMake(2048, 1536), "ipadhd" };

#if (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_480X320)
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(480, 320);
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_480X800)
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(800, 480);
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_1024X768)
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(1024, 768);
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_2048X1536)
static cocos2d::CCSize designResolutionSize = cocos2d::CCSizeMake(2048, 1536);
#elif (TARGET_DESIGN_RESOLUTION_SIZE == DESIGN_RESOLUTION_1280X800)
static CCSize designResolutionSize = cocos2d::CCSizeMake(1280, 800);
#else
#error unknown target design resolution!
#endif

// The font size 24 is designed for small resolution, so we should change it to fit for current design resolution
#define TITLE_FONT_SIZE  (cocos2d::CCEGLView::sharedOpenGLView()->getDesignResolutionSize().width / myResource.size.width * 24)

#endif /* __APPMACROS_H__ */

现在我们可以在appdelegate中使用这个类..所以我的appdelegate看起来像......

#include "AppDelegate.h"
#include "MenuLayer.h"
#include "AppMacros.h"
#include "SimpleAudioEngine.h"
#include "cocos2d.h"


USING_NS_CC;


AppDelegate::AppDelegate() {

}

AppDelegate::~AppDelegate() {

}
void AppDelegate::initGLContextAttrs()
{
    //set OpenGL context attributions,now can only set six attributions:
    //red,green,blue,alpha,depth,stencil
    GLContextAttrs glContextAttrs = {8, 8, 8, 8, 24, 8};

    GLView::setGLContextAttrs(glContextAttrs);
}

bool AppDelegate::applicationDidFinishLaunching() {

    // initialize director
    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if(!glview) {
        glview = GLViewImpl::create("My Game");
        director->setOpenGLView(glview);
    }

    CCLOG("%s","applicationDidFinishLaunching ");
    // initialize director
//  CCDirector* pDirector = CCDirector::sharedDirector();
//  CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

    director->setOpenGLView(glview);

    // Set the design resolution
    glview->setDesignResolutionSize(designResolutionSize.width,
            designResolutionSize.height, kResolutionFixedWidth);

    //CCSize frameSize = pEGLView->getFrameSize();
    CCSize frameSize = director->getVisibleSize();

    // if the frame's height is larger than the height of medium resource size, select large resource.
    if (frameSize.width > myResource.size.width) {

        director->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 > mediumResource.size.width) {

        director->setContentScaleFactor(
                myResource.size.width / designResolutionSize.width);

    } else if (frameSize.width > mysmallResource.size.width) {

        director->setContentScaleFactor(
                designResolutionSize.width / mediumResource.size.width);

    } else if (frameSize.width > smallResource.size.width) {

        director->setContentScaleFactor(
                designResolutionSize.width / mediumResource.size.width);

    }
    // if the frame's height is smaller than the height of medium resource size, select small resource.
    else {

        director->setContentScaleFactor(
                designResolutionSize.width / smallResource.size.width);

    }

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

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


    CCScene *pScene = MenuLayer::scene();


    director->runWithScene(pScene);



    return true;
}

// 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()->stopAnimation();

    // if you use SimpleAudioEngine, it must be pause
    CocosDenshion::SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();


}

// this function will be called when the app is active again
void AppDelegate::applicationWillEnterForeground() {
    CCDirector::sharedDirector()->startAnimation();

    // if you use SimpleAudioEngine, it must resume here
    CocosDenshion::SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();


}
