#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS || CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
	glLineWidth(2.0f);
	//glEnable(GL_LINE_WIDTH);
#else
	glLineWidth(2.0f);
	glEnable(GL_LINE_SMOOTH);
#endif

	ccDrawColor4F(1.0f,1.0f,0.5f);

	BattleTerrain *terrain = BattleScene::getCurrentScene()->getTerrain();
	if(!terrain) return;

	for (int i = 0; i < terrain->getWidth(); ++i)
	{
		GridPosition down = GridPosition(i,0);
		GridPosition up = GridPosition(i,BattleScene::getCurrentScene()->getTerrain()->getHeight());
		CCPoint downPoint = ccp(GridUtil::sharedGridUtil().gridEdgeToPix(down).x,GridUtil::sharedGridUtil().gridEdgeToPix(down).y);
		CCPoint upPoint = ccp(GridUtil::sharedGridUtil().gridEdgeToPix(up).x,GridUtil::sharedGridUtil().gridEdgeToPix(up).y);
		ccDrawLine(downPoint,upPoint);
	}

新项目的方式，重写新的draw函数，在onDraw中绘制

void SceneLayer::draw(Renderer *renderer,const Mat4& transform,uint32_t flags)
{
	_customCommand.init(_globalZOrder,transform,flags);
	_customCommand.func = CC_CALLBACK_0(SceneLayer::onDraw,this,flags);
	renderer->addCommand(&_customCommand);
}

先将drawNode节点添加到父节点中

_drawNode = CCDrawNode::create();
addChild(_drawNode);

_drawNode->clear();

_drawNode->clear();
	for (int i = 0; i < terrain->getWidth(); ++i)
	{
		GridPosition down = GridPosition(i,GridUtil::sharedGridUtil().gridEdgeToPix(up).y);
		_drawNode->drawLine(downPoint,upPoint,ccColor4F(1.0f,0.5f));
		//ccDrawLine(downPoint,upPoint);
	}
