一步一步CocosBuilder(4)[完结]

发表于   |   分类于 ，   |  

这一节也是很轻松, 主要是牵涉到Timeline的切换. 其他的都是简单的界面制作.
所以CocosBuilder的威力也体现在这里, 很少的代码就能驱动界面了.

我们这次先做Particle System, Scroll View, 最后以Animations收官.

#####1
制作Particle System和Scroll View的界面很简单,我们也是以程序为重点, 所以不再赘述.
只需要一句this->openTest("ccb/Scroll.ccbi");就可以调用新的界面了.
其他诸如绑定之类相信大家已经是轻车熟路啦.

好吧, 我承认一点, 制作Animations的界面的时候, 我直接复制了例子中的节点.
5个Timeline, 还是很复杂的, 应该是一个非常精细的工作. 向美术们致敬.

    return NULL;
}
void AnimationsLayer::setAnimationManager(cocos2d::extension::CCBAnimationManager *pAnimationManager)

    CC_SAFE_RELEASE_NULL(mAnimationManager);
    mAnimationManager = pAnimationManager;
    CC_SAFE_RETAIN(mAnimationManager);
}
void AnimationsLayer::onIdle(cocos2d::CCObject *pSender, cocos2d::extension::CCControlEvent pCCControlEvent)
{
    this->mAnimationManager->runAnimationsForSequenceNamedTweenDuration("Idle", 0.3f);
}
void AnimationsLayer::onJump(cocos2d::CCObject *pSender, cocos2d::extension::CCControlEvent pCCControlEvent)
{
    this->mAnimationManager->runAnimationsForSequenceNamedTweenDuration("Jump", 0.3f);
}

{
    this->mAnimationManager->runAnimationsForSequenceNamedTweenDuration("Funky", 0.3f);
}

整个代码还是很简单. 和以前的几个例子稍微有点不同的是在调用的时候, 需要把CCBReader里面的AnimationManger传入.
好, 还是看下调用的代码吧.

    reader->autorelease();

    {
        //获取AnimationManger 并传给AnimationsLayer
        ((AnimationsLayer*)node) ->setAnimationManager(reader->getAnimationManager());
        
        scene->addChild(node);
    }
    
    this->mTitleLabelTTF->setString(pCCBFileName);

}

###后记
看到微博上@做游戏的老G 吐槽说CocosBuilder如何不好用, 学习难度比较大. 我也是很认可这一点.
但是只要是坚持把TestCpp例子完全读完了, 相信掌握CocosBuilder也是很快能够做到的.
既然你看完了这个教程. 相信你也已经能够很好地驾驭CocosBuilder. 关键还在实践呦!

微博上@Ghost_233 说了一个很好的思路, 直接从ccb文件中生成对应的C++类, 而且他还做了一些实践.
我暂时还没有研究他的代码, 不过肯定是可行. 这是一个很赞的思路.
希望大家能动手, 最好合作出来一个较好的工具来, 我想, 是不是集成到CocosBuilder会更好?

谢谢大家耐心看完我的文章.
