CCMoveTo动作不流畅

Cocos2d-x
#1

版本：cocos2dx 2.2.2
现象：使用CCMoveTo时，动作不流畅，存在卡顿和跳动

求解，是引擎本身的bug么

#2

开帧数看一下，还有就是你真机上看测了么？ 如果电脑配置不行，虚拟机会卡顿的

#3

小米3，每秒60帧左右

#4

代码如下：
CCFiniteTimeAction* placeAction = CCPlace::create(ccp(size.width / 2, size.height + mSprite->getContentSize().height / 2));
CCMoveTo* moveAction = CCMoveTo::create(5, ccp(size.width / 2, -mSprite->getContentSize().height / 2));
CCSequence* action = CCSequence::create(placeAction, moveAction, NULL);
CCRepeat* repeatAction = CCRepeat::create(action, 100);

mSprite->runAction(repeatAction);

#5

用setPositon吧

#6 
mSprite->setPosition(ccp(size.width / 2, size.height + size.height / 2));
CCMoveTo* moveAction = CCMoveTo::create(5, ccp(size.width / 2, -size.height / 2));

mSprite->runAction((CCMoveTo*)moveAction->copy());


     这样还是有卡顿和跳动
#7

看一下是否在别的地方设置位置或者是否多次调用这些语句

#8

只有这一个场景，代码如下（cocos2dx 2.2.2），还是会有卡顿和跳动：

bool GameArcade::init() {
if (!CCScene::init()) {
return false;
}

CCSize size = CCDirector::sharedDirector()->getVisibleSize();

mBgLayer = CCLayer::create();

mSprite = CCSprite::create("whiteBlock.png");
mSprite->setPosition(ccp(size.width / 2, size.height / 2));

mBgSprite = CCSprite::create("green2.jpg");
mBgSprite->setPosition(ccp(size.width / 2, size.height / 2));

CCSize bgSpriteOriginSize = mBgSprite->getContentSize();
mBgSprite->setScaleX(size.width / bgSpriteOriginSize.width);
mBgSprite->setScaleY(size.height / bgSpriteOriginSize.height);

CCSize spriteOriginSize = mSprite->getContentSize();
mSprite->setScaleX(size.width / spriteOriginSize.width);
mSprite->setScaleY(size.height / spriteOriginSize.height);

mBgLayer->addChild(mBgSprite, 0);
mBgLayer->addChild(mSprite, 5);

this->addChild(mBgLayer);

/*
 CCFiniteTimeAction* placeAction = CCPlace::create(ccp(size.width / 2, size.height + size.height / 2));
 CCMoveTo* moveAction = CCMoveTo::create(5, ccp(size.width / 2, -size.height / 2));
 CCSequence* action = CCSequence::create(placeAction, moveAction, NULL);
 CCRepeat* repeatAction = CCRepeat::create(action, 100);

 mSprite->runAction(repeatAction);
 */
mSprite->setPosition(ccp(size.width / 2, size.height + size.height / 2));
CCMoveTo* moveAction = CCMoveTo::create(5, ccp(size.width / 2, -size.height / 2));

mSprite->runAction((CCMoveTo*)moveAction->copy());

return true;

}

#9

那可能是帧数不稳定吧

#10

好像确实是刷帧不稳定导致的，应该怎么解决呢
我试了把fps设置为大于1/60，但不起作用

#11

这个具体对待吧，例如在游戏过程中加载图片资源，可能会造成游戏卡顿，，，你应该做优化，看看什么地方花费的时间多；；；；屏蔽一些你认为有影响的语句，逐步排除吧

#12

你的图片资源是不是很大
