[cocos2dx笔记002] 坦克动画
第一：没有美术，只好自己用PS。先用PS在原来的4个方向上，做一个履带差异的4方向坦克。
第二：用SpritePacker打包成tankbase.plist。然后用CCSpriteFrameCache加载到内存中。
CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("basetank.plist");

第三：封装一个动画的函数
/********************************************************************************
Title: 生成指定方向的坦克动画Action
FullName: zdh::XGameGlobal::createBasetankAni
Access: public
@param [in] param_Direction 方向，参见EnumDirection，如果是无效方向，视为ED_UP
@return CCRepeatForever * 返回坦克动画的Action对象
@author zdhsoft
@date 2014/03/24
@file xgameglobal.h
********************************************************************************/
CCRepeatForever * createBasetankAni(int param_Direction) const
{
//创建帧资源的数组
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);
//创建动画对象 第二个参数是每帧间隔时间 这里是0.1秒
CCAnimation * pAni = CCAnimation::createWithSpriteFrames(st_frame_list, 0.1f);
//创建动画Action
CCAnimate * pAniAction = CCAnimate::create(pAni);
//创建重复Action
CCRepeatForever *pAction = CCRepeatForever::create(pAniAction);
st_frame_list->release();
return pAction;
}
第四：在玩家对象设置方向和对象初始化的时候，设置动画
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);
设置方向:
/********************************************************************************
Title: 设置坦克的方向
FullName: zdh::XPlayer::setDirection
Access: public
@param [in] paramDirection 如果是无效的方向，会视为ED_UP
@return bool
- true 设置成功
- false 设置失败
@author zdhsoft
@date 2014/03/24
@file xplayer.h
********************************************************************************/
bool setDirection(const int paramDirection)
{
if (paramDirection >= ED_UP &¶mDirection <= ED_RIGHT) //如果是无效方向，则设置不成功
{
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; //变更方向
return true;
}
}
return false;
}
这样就OK了！
