前几天就是懒了,白天上课,然后晚上回来几乎也弄不了什么就睡了,所以就没发什么,今天总算打起精神继续学习了。我们今天说CCAction包括,CCAction,CCFiniteTimeAction,CCSpeed,CCFollow,
我们开始吧,上图:
首先CCAction分成三类,分别是CCFiniteTimeAction,CCSpeed,和CCFollow
CCFiniteTimeAction又分成两类,上图的CCAction应该写成CCFiniteTimeAction,
CCFiniteTimeAction包括CCActionInstant(瞬时动作),CCActionInterval(延时动作)
瞬时动作又包括以上的几种,这些动作都是在一瞬间完成的,我们看不见变换的过程,应为他太快了。你可能会问CCPlace和setPosition不都差不多嘛,何必多此一举来用CCPlace还包装成一个action,其实这些都可以封装成为一个顺序,这不正是CCPlace和setPosition的区别了吗。
代码示例:
- CCFlipY *flipx = CCFlipY::create(true);
- CCHide *hide = CCHide::create();
- CCToggleVisibility *togglevis = CCToggleVisibility::create();
- CCPlace *place = CCPlace::create(ccp(200,200));
以上的几种相对难理解的是假动作CCCallFunc,所以我们具体说说这个。假动作就是没有动作,其实他只是一个回调。
- <span style="font-size:24px;">CCCallFunc *callfun = CCCallFunc::create(this,callfunc_selector(T14CCActionDemo::funcall));
- CCCallFuncN *callfunc = CCCallFuncN::create(this,callfuncN_selector(T14CCActionDemo::funcallN));
- CCCallFuncND *callfuncnd = CCCallFuncND::create(this,callfuncND_selector(T14CCActionDemo::funcallND),(void *)("90"));
- CCCallFuncO *callfunco = CCCallFuncO::create(this,callfuncO_selector(T14CCActionDemo::funcallO),woman);</span>
- void T14CCActionDemo::funcall()
- {
- CCLog("action is ok");
- }
- void T14CCActionDemo::funcallN(CCNode* node)
- {
- node->setVisible(false);
- }
- void T14CCActionDemo::funcallND(CCNode* pnode,void* pdata)
- {
- CCString *str = CCString::createWithFormat("%s",pdata);
- pnode->setRotation(str->floatValue());
- }
- void T14CCActionDemo::funcallO(CCObject* obj)
- {
- CCSprite *woman = (CCSprite *)obj;
- CCMoveBy *moveby = CCMoveBy::create(2,ccp(200,0));
- woman->runAction(moveby);
- }
CCCallFunc是一个最基础的假动作,CCCallFuncN可以在回调的时候得到CCNode,CCCallFuncND可以在回调的时候得到CCNode,和Data,Data就是我们手动加的数据,上面的例子就是那个"90"的字符串啊。CCCallFuncO就是可以在会掉的时候得到我们定义的CCObject。
这上面的全部都是延时动作,贴上示例代码:
- CCMoveTo *moveto = CCMoveTo::create(3,ccp(300,100));
- CCMoveBy *moveby = CCMoveBy::create(2,0));
- CCMoveBy *moveby2 = CCMoveBy::create(2,0));
- CCJumpTo *jumpto = CCJumpTo::create(3,100),50,3);
- CCJumpBy *jumpby = CCJumpBy::create(3,0),150,3);
- CCScaleTo *scaleTo = CCScaleTo::create(3,2);
- CCScaleBy *scaleby = CCScaleBy::create(3,2);
- CCRotateTo *rotateto = CCRotateTo::create(3,-90);
- CCRotateBy *rotateBy = CCRotateBy::create(3,-90);
- CCSpawn *spawn = CCSpawn::create(rotateto,scaleby,NULL);
- CCSequence *sequence = CCSequence::create(rotateto,NULL);
- CCSkewTo *skewto = CCSkewTo::create(3,222,222);
- CCTintTo *tintto = CCTintTo::create(3,255,255);
- CCFadeIn *fadein = CCFadeIn::create(3);
- CCFadeOut *fadeout = CCFadeOut::create(3);
- CCFadeTo *fadeto = CCFadeTo::create(3,100);
- CCPointArray *pointarray = CCPointArray::create(6);
- pointarray->addControlPoint(ccp(100,160));
- pointarray->addControlPoint(ccp(200,250));
- pointarray->addControlPoint(ccp(300,160));
- pointarray->addControlPoint(ccp(450,160));
- CCCardinalSplineTo *cardinal = CCCardinalSplineTo::create(10,pointarray,1);
- CCBlink *blink = CCBlink::create(3,5);
- CCEaseExponentialIn *exponentin = CCEaseExponentialIn::create(moveby);
- CCEaseBackIn *bakcin = CCEaseBackIn::create(moveby);
方法好多好多,具体的可以看api,实在不明白的可以根据上面的实例看api,关于一些缓冲可以自己动手做实验,这里我再怎么说也不顶你自己实践一把。
最后还有CCSpeed和CCFollow,CCSpeed主要就是变速嘛:
- CCSpeed *speed = CCSpeed::create(moveby,5);//将速度提升5倍
话说CCFollow我也是半吊子,不敢乱说,自己只亲手做了个实验,今天就弄到这里吧
行啦,博主最近要早睡啦,11点前必须睡,晚安啦~
