Cocos2d-x 3.2 大富翁游戏项目开发-第八部分 角色按路径行走

路径获得之后，我们就可以让角色按照路径行走了，当点击go按钮的时候，我们调用player的startGo()方法，传入的参数就是保存了路径的2个一维数组

void GameBaseScene::goButtonCallback(cocos2d::CCObject *pSender)
{
	RouteNavigation::getInstance()->getPath(player1,3,canPassGrid,tiledRowsCount,tiledColsCount);
	std::vector colVector = RouteNavigation::getInstance()->getPathCols_vector();
	std::vector rowVector = RouteNavigation::getInstance()->getPathRow_vector();
	for(int i=0;istartGo(rowVector,colVector);
}

给类RicherPlayer添加相应的startGo方法

void RicherPlayer::startGo(std::vector rowVector,std::vector colVector)
{
	//获取游戏控制器RicherGameController，调用其中的startRealGo（）方法，开始真正的角色行走
	RicherGameController* rgController = RicherGameController::create();
	addChild(rgController);
	rgController->startRealGo(rowVector,colVector,this);
}

void RicherGameController::startRealGo(std::vector rowVector,std::vector colVector,RicherPlayer* richerPlayer)
{
	currentRow = rowVector[0];	currentCol = colVector[0]; //获取第一个位置的行列值
	nextRow =0;	nextCol =0; //下一步的行列值
	//创建上下左右的动作，并放入缓存
	if(!AnimationCache::getInstance()->animationByName(left_animation))
	{
AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(richerPlayer->getAnim_left_vector(),playerGoPerFrameTime),left_animation);
	}
	if(!AnimationCache::getInstance()->animationByName(right_animation))
	{
AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(richerPlayer->getAnim_right_vector(),playerGoPerFrameTime),right_animation);
	}
	if(!AnimationCache::getInstance()->animationByName(down_animation))
	{
AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(richerPlayer->getAnim_down_vector(),playerGoPerFrameTime),down_animation);
	}
	if(!AnimationCache::getInstance()->animationByName(up_animation))
	{
AnimationCache::getInstance()->addAnimation(Animation::createWithSpriteFrames(richerPlayer->getAnim_up_vector(),playerGoPerFrameTime),up_animation);
	}
	//从缓存中取得上下左右的动作，创建相应的动画
	 left = Animate::create(AnimationCache::getInstance()->animationByName(left_animation));
	 right =Animate::create( AnimationCache::getInstance()->animationByName(right_animation));
	 down =Animate::create(AnimationCache::getInstance()->animationByName(down_animation));
	 up = Animate::create(AnimationCache::getInstance()->animationByName(up_animation));
	//retain 一下，引用计数加一，防止动画被清除
	 left->retain();
	 right ->retain();
	 down->retain();
	 up->retain();
	//根据参数给相应变量赋值
	_rowVector=rowVector;
	_colVector=colVector;
	_richerPlayer =richerPlayer;
	stepHasGone = 0;//角色已经走了几步
	stepsCount = _rowVector.size()-1;//取得路径需要走的步数，因为第一个是当前位置的行列，所以不计入步数
	moveOneStep();//开始行走，先走一步，走完一步后，再走下一步
}
