前端之家收集整理的这篇文章主要介绍了
cocos2d-x 帧动画的三种实现,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
//获取屏幕大小
Size visibleSize = Director::getInstance()->getVisibleSize();
//auto size = Director::getInstance()->getWinSize();
//帧动画的创建
//方式一,通过多张图片来创建
auto sprite1 = Sprite::create("grossini_dance_05.png");
sprite1->setPosition(Vec2(visibleSize.width*0.3,visibleSize.height/2));
this->addChild(sprite1);
//创建帧动画序列,名词形式
auto animation = Animation::create();
for (int i=5; i<11; i++)
{
char szName[100] = {0};
sprintf(szName,"grossini_dance_%02d.png",i);
animation->addSpriteFrameWithFile(szName);
}
//设置帧动画属性
animation->setDelayPerUnit(2.0f / 6); //每一帧停留的时间,2秒时间完成6幅图片显示,切记要写成2.0f形式!
animation->setRestoreOriginalFrame(true); //播放完后回到第一帧
auto animate = Animate::create(animation);
sprite1->runAction(RepeatForever::create(animate));
//方式二,通过一张集合的图片来创建
//创建2D纹理
auto texture = Director::getInstance()->getTextureCache()->addImage("dragon_animation.png");
//建立图片帧
auto frame0 = SpriteFrame::createWithTexture(texture,Rect(132*0,132*0,132,132));
auto frame1 = SpriteFrame::createWithTexture(texture,Rect(132*1,132));
auto frame2 = SpriteFrame::createWithTexture(texture,Rect(132*2,132));
auto frame3 = SpriteFrame::createWithTexture(texture,Rect(132*3,132));
auto frame4 = SpriteFrame::createWithTexture(texture,132*1,132));
auto frame5 = SpriteFrame::createWithTexture(texture,132));
auto sprite2 = Sprite::createWithSpriteFrame(frame0);
sprite2->setPosition(Vec2(visibleSize.width/2,visibleSize.height/2));
this->addChild(sprite2);
//保存图片帧
//Vector<cocos2d::AnimationFrame *> array;
Vector<cocos2d::SpriteFrame *> array;
array.pushBack(frame0);
array.pushBack(frame1);
array.pushBack(frame2);
array.pushBack(frame3);
array.pushBack(frame4);
array.pushBack(frame5);
auto animation2 = Animation::createWithSpriteFrames(array,0.2f); //此处createWithSpriteFrames()函数确实每帧间隔时间参数,需自行加上去!!!
sprite2->runAction(RepeatForever::create(Animate::create(animation2)));
//方式三,通过.plist 文件来创建
auto cache = SpriteFrameCache::getInstance();
cache->addSpriteFramesWithFile("animate.plist");
auto sprite3 = Sprite::createWithSpriteFrameName("grossini_dance_05.png");
sprite3->setPosition(Vec2(visibleSize.width*0.7,visibleSize.height/2));
this->addChild(sprite3);
Vector<cocos2d::SpriteFrame *> arr;
char str[100] = {0};
for (int i=1; i<15; i++)
{
sprintf(str,i);
auto frame_2 = cache->SpriteFrameCache::getInstance()->getSpriteFrameByName(str); //3.2版本有改变
arr.pushBack(frame_2);
}
auto animation3 = Animation::createWithSpriteFrames(arr,0.2f); //此处也不要忘记加上时间间隔参数
sprite3->runAction(RepeatForever::create(Animate::create(animation3)));
