要實現象棋的運動，首先要確定選中的目標，再其次確定選中的位置，再確定選擇的位置是否有對方棋子

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; }

不同的棋子運動規則不同，車，馬，炮等都有不同的運動方式

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

將的移動

{

士的移動

if(x<3||x>5) return false;if(_redSide==s->getRed()){if(y<0||y>2) return false;}else{if(y < 7 || y > 9) return false;}return true; }

相的移動

int xo=s->getX();
int yo=s->getY();

炮的移動
bool SceneGame::canMovePao(int moveid, int killid, int x, int y)
{
Stone* s = _s[moveid];
int xo = s->getX();
int yo = s->getY();

if(killid != -1 && this->getStoneCount(xo, yo, x, y) == 1){return true;}else if(killid==-1){return canMoveChe(moveid,x,y);}return false;} 兵的移動 bool SceneGame::canMoveBing(int moveid, int x, int y) {Stone* s = _s[moveid];int xo = s->getX();int yo = s->getY();int xoff = abs(xo-x);int yoff = abs(yo-y);int d = xoff*10 + yoff;if(d != 1 && d != 10) return false;if(_redSide==s->getRed()){if(y<yo) return false;if(yo<=4&&y==yo) return false;}else{if(y>yo) return false;if(yo>=5&&y==yo) return false;}return true; }
