要实现象棋的运动，首先要确定选中的目标，再其次确定选中的位置，再确定选择的位置是否有对方棋子

void SceneGame::setSelectId(int id)
{if(id==-1){return;}if(_s[id]->getRed()!=_redTrun)return;_selectid=id;_selectSprite->setVisible(true);_selectSprite->setPosition(_s[_selectid]->getPosition());
}

void SceneGame::moveStone(int moveid, int killid, int x, int y)
{
if(killid != -1&&_s[moveid]->getRed()==_s[killid]->getRed())
{
setSelectId(killid);
return;
}

    bool bCanMove = canMove(moveid, killid, x, y);if(bCanMove == false)return;//set stepStep* step = Step::create(moveid, killid, _s[moveid]->getX(),_s[moveid]->getY(), x, y);_steps->addObject(step);_s[moveid]->setX(x);_s[moveid]->setY(y);//_s[moveid]->setPosition(getStonePos(x,y));CCMoveTo *moveto=CCMoveTo::create(.5f,getStonePos(x,y));CCCallFuncND *call=CCCallFuncND::create(this,callfuncND_selector(SceneGame::moveComplete),(void*)(intptr_t)killid);CCSequence *sequence=CCSequence::create(moveto,call,NULL);_s[moveid]->setZOrder(_s[moveid]->getZOrder()+1);_s[moveid]->runAction(sequence);//_selectid=-1;//_selectSprite->setVisible(false);//_redTrun=!_redTrun;
}

不同的棋子运动规则不同，车，马，炮等都有不同的运动方式

总函数
bool SceneGame::canMove(int moveid, int killid, int x, int y)
{
Stone *s=_s[moveid];
switch(s->getType())
{
case Stone::JIANG:
return canMoveJiang(moveid, killid, x, y);

    case Stone::SHI:return canMoveShi(moveid, x, y);case Stone::XIANG:return canMoveXiang(moveid, x, y);case Stone::CHE:return canMoveChe(moveid, x, y);case Stone::MA:return canMoveMa(moveid, x, y);case Stone::PAO:return canMovePao(moveid, killid, x, y);case Stone::BING:return canMoveBing(moveid, x, y);}return false;
}

将的移动

相的移动

车的移动

炮的移动
