[cocos2dx筆記002] 坦克動畫
第一：沒有美術(shù)，只好自己用PS。先用PS在原來的4個(gè)方向上，做一個(gè)履帶差異的4方向坦克。
第二：用SpritePacker打包成tankbase.plist。然后用CCSpriteFrameCache加載到內(nèi)存中。
CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("basetank.plist");

第三：封裝一個(gè)動畫的函數(shù)
/********************************************************************************
Title: 生成指定方向的坦克動畫Action
FullName: zdh::XGameGlobal::createBasetankAni
Access: public
@param [in] param_Direction 方向，參見EnumDirection，如果是無效方向，視為ED_UP
@return CCRepeatForever * 返回坦克動畫的Action對象
@author zdhsoft
@date 2014/03/24
@file xgameglobal.h
********************************************************************************/
CCRepeatForever * createBasetankAni(int param_Direction) const
{
//創(chuàng)建幀資源的數(shù)組
CCArray* st_frame_list = new CCArray(2);
CCSpriteFrame * pF1 = CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(getDirectionResName(param_Direction, 0));
CCSpriteFrame * pF2 = CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(getDirectionResName(param_Direction, 1));
st_frame_list->addObject(pF1);
st_frame_list->addObject(pF2);
//創(chuàng)建動畫對象 第二個(gè)參數(shù)是每幀間隔時(shí)間 這里是0.1秒
CCAnimation * pAni = CCAnimation::createWithSpriteFrames(st_frame_list, 0.1f);
//創(chuàng)建動畫Action
CCAnimate * pAniAction = CCAnimate::create(pAni);
//創(chuàng)建重復(fù)Action
CCRepeatForever *pAction = CCRepeatForever::create(pAniAction);
st_frame_list->release();
return pAction;
}
第四：在玩家對象設(shè)置方向和對象初始化的時(shí)候，設(shè)置動畫
初始化：
CCSprite * p1Pic = CCSprite::createWithSpriteFrameName(GAME_GLOBAL->getDirectionResName(ED_UP));
p1Pic->setPosition(GetPosition(pPlayerLayer, "Player1"));
p1Pic->setAnchorPoint(ccp(0, 0));
this->addChild(p1Pic);
p1Pic->runAction(GAME_GLOBAL->createBasetankAni(ED_UP));
m_Player1.setDraw(p1Pic);
設(shè)置方向:
/********************************************************************************
Title: 設(shè)置坦克的方向
FullName: zdh::XPlayer::setDirection
Access: public
@param [in] paramDirection 如果是無效的方向，會視為ED_UP
@return bool
- true 設(shè)置成功
- false 設(shè)置失敗
@author zdhsoft
@date 2014/03/24
@file xplayer.h
********************************************************************************/
bool setDirection(const int paramDirection)
{
if (paramDirection >= ED_UP &¶mDirection <= ED_RIGHT) //如果是無效方向，則設(shè)置不成功
{
if (paramDirection != m_Direction)
{
if (m_Draw != nullptr)
{
m_Draw->stopAllActions();
m_Draw->setDisplayFrame(CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(GAME_GLOBAL->getDirectionResName(paramDirection)));
m_Draw->runAction(GAME_GLOBAL->createBasetankAni(paramDirection));
}
m_Direction = paramDirection; //變更方向
return true;
}
}
return false;
}
這樣就OK了！
