喜欢游戏，喜欢cocos2d-x开发，刚刚开始学习cocos2d-x，有什么不好的地方希望大伙指出

Watch Out!（中文名：贱鸟跳跳） iOS非常好玩的手游，用cocos2d-x v3.2模拟写了一遍

先看看游戏图：

主要代码：

圆圆(左边的) / 方方(右边的) 跳跃：

//判断触摸的位置（左/右）
	if(location.x >= winSize.width / 2) {
		//跳跃
		auto jumpAction = fangfang->getActionByTag(tag_fangfangAction);
		if(!jumpAction) {
			fangfang->setSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("fangfang_jump.png"));
			jumpAction = Sequence::create(JumpBy::create(0.5, Vec2(-80,0), _jumpHeight, 1),
				CallFunc::create(CC_CALLBACK_0(WatchOut::callbackRunAction, this, fangfang)),
				nullptr);
			jumpAction->setTag(tag_fangfangAction);
			fangfang->runAction(jumpAction);
		}else if(jumpAction->isDone()) { //下一次点击的时候，只在跳跃完成才有效
			fangfang->setSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("fangfang_jump.png"));
			fangfang->runAction(jumpAction);
		}
	}

碰撞检测：

if(yyBox.intersectsRect(ffBox)) {
			_gameState = GAME_STATE_OVER;
			SimpleAudioEngine::getInstance()->playEffect(music_player_die);
			auto startGame = this->getChildByTag(tag_start_game);
			startGame->setVisible(true);

			/* 爆炸效果 */
			auto pExpVec = Vec2::ZERO;
			auto pExpColor = Color4F::BLUE;
			auto pExpTextureRect = Rect::ZERO;
			//根据当前TAG来决定爆炸对象
			if(_currentTag == yuanyuan->getTag()) {
				yuanyuan->setVisible(false);
				pExpVec = Vec2(
					yuanyuan->getPositionX() + yuanyuan->getContentSize().width / 4,
					yuanyuan->getPositionY() + yuanyuan->getContentSize().height / 4);
				pExpColor = Color4F(57, 99, 207, 255);
				pExpTextureRect = Rect(2,2,9,9);
			}else {
				fangfang->setVisible(false);
				pExpVec = Vec2(
					fangfang->getPositionX() + fangfang->getContentSize().width / 4,
					fangfang->getPositionY() + fangfang->getContentSize().height / 4);
				pExpColor = Color4F(212, 74, 123, 255);
				pExpTextureRect = Rect(13,2,9,9);
			}
			auto pExplostion = ParticleExplosion::create();
			pExplostion->setStartSize(3);
			pExplostion->setStartColor(pExpColor);
			pExplostion->setEndColor(pExplostion->getStartColor());
			pExplostion->setLife(0.1);
			pExplostion->setTotalParticles(100);
			pExplostion->setRotationIsDir(false);
			pExplostion->setAutoRemoveOnFinish(true);
			pExplostion->setPosition(pExpVec);
			pExplostion->setTextureWithRect(Director::getInstance()->getTextureCache()->addImage("watchout.png"), pExpTextureRect);
			pExplostion->setScale(0.5);
			top->addChild(pExplostion, 10);
		}else if(ffBox.getMaxX() < yyBox.getMinX() && 
			ffBox.getMinY() == 2 && 
			yyBox.getMinY() == 2) {//如果没有碰撞 && 方方/圆圆都没处于跳跃状态
			_gameState = GAME_STATE_RESET; //游戏重置
			SimpleAudioEngine::getInstance()->playEffect(music_score);
			yuanyuan->setVisible(false);
			fangfang->setVisible(false);
			_score ++;

			//分数Label改变
			auto scoreBg = this->getChildByTag(tag_score_bg);
			LabelTTF* scoreLabel = (LabelTTF*)scoreBg->getChildByTag(tag_score_label);
			scoreLabel->setString(StringUtils::format("%i", _score));

			//分数增加(等级增加)，速度增加，背景颜色改变
			if(_score % 6 == 0) {
				_runSpeed += 0.5;
				int bgLevel = _score / 6;
				LayerColor* topBg = (LayerColor*)this->getChildByTag(tag_bg_top);
				LayerColor* bottomBg = (LayerColor*)this->getChildByTag(tag_bg_bottom);
				if(bgLevel == 1) {
					topBg->setColor(color_level_1);
					bottomBg->setColor(color_level_1_b);
					scoreLabel->setColor(color_level_1_cc3);
				}else if(bgLevel == 2) {
					topBg->setColor(color_level_2);
					bottomBg->setColor(color_level_2_b);
					scoreLabel->setColor(color_level_2_cc3);
				}
			}
		}
