动画，不同于动作，动画并非属性的改变。而是对帧的播放。

方法一
ccsprite * sp = ccsprite::create(“animation/p_2_01.png”);
sp->setposition(ccp(240,160));
//注意：这里的ccrectmake中的参数都是相对自己来说的，前两个参数定义了一个点，80,80表示的是矩形的长，宽。
ccspriteframe * frame1 =
ccspriteframe::create("animation/p_2_01.png",ccrectmake(0,0,80,80))
;
ccspriteframe * frame2 =
ccspriteframe::create("animation/p_2_02.png",ccrectmake(0,0,80,80))
ccspriteframe * frame3 =
ccspriteframe::create("animation/p_2_03.png",ccrectmake(0,0,80,80))
ccspriteframe * frame4 =
ccspriteframe::create("animation/p_2_04.png",ccrectmake(0,0,80,80))
ccspriteframe * frame5 =
ccspriteframe::create("animation/p_2_05.png",ccrectmake(0,0,80,80))
ccspriteframe * frame6 =
ccspriteframe::create("animation/p_2_06.png",ccrectmake(0,0,80,80))
ccspriteframe * frame7 =
ccspriteframe::create("animation/p_2_07.png",ccrectmake(0,0,80,80))
ccspriteframe * frame8 =
ccspriteframe::create("animation/p_2_08.png",ccrectmake(0,0,80,80))
ccanimation * animation = ccanimation::create();
animation->addspriteframe(frame1);
animation->addspriteframe(frame2);
animation->addspriteframe(frame3);
animation->addspriteframe(frame4);
animation->addspriteframe(frame5);
animation->addspriteframe(frame6);
animation->addspriteframe(frame7);
animation->addspriteframe(frame8);
animation->setdelayperunit(0.1f);
animation->setloops(kccrepeatforever);
ccanimate *animate = ccanimate::create(animation);
sp->runaction(animate);
addchild(sp);

方法二（对一的改进）
ccspriteframecache::sharedspriteframecache()->addspriteframewithfile(“animation/plant.plist”);
char bufname[100];
ccarray * array = ccarray::create();
for(int i = 1;i<= 8;i++) {
memset(bufname,”p_2_0%d.png”,i);
ccspriteframe * frame = ccspriteframecache::sharedspriteframecache()->spriteframebyname(bufname);
array->addobject(frame);
}
ccanimation * animation = ccanimation::createwithspriteframes(array,0.2f);
ccanimate * animate = ccanimate::create(animation);

更简单的
ccspriteframecache::sharedspriteframecache()->addspriteframeswithfile(“animation/plant.plist”);
for(int i = 1;i<=8;i++){
memset(bufname,sizeof(bufname),0);
sprint(bufname,”p_2_0%d.png”,i);
animation->addspriteframe(ccspriteframecache::sharedspriteframecache()->spriteframebyname(bufname));
animation->setdelayperunit(0.2f);
