Deluxe Edition aircraft war series (6)-source code

The last article describes the main logic judgment in the game. After the above work is fully prepared, the main logic of the game will become very clear, next, you will see that all the logic is so clear and natural, because the preparations have been fully prepared. Here we only integrate the previous work and add some game judgment elements.

At the same time, the source code will provide the link address at the end of the article. The source code is hosted on GitHub. Everything is open-source and free of charge. In the current environment, open-source is the king, so sharing can win-win, I always think this is right. You have an idea. After communication and sharing, we both have two ideas. Why not.

Well, back to the question, the main judgment logic of the game is in the gamescene scenario, including the gamelayer layer, where the game logic is judged.

Let's take a look at the content of gamescene. h:

# Include "cocos2d. H "# include" planelayer. H "# include" bulletsprite. H "# include" enemylayer. H "using_ns_cc; Class gamelayer: Public cocos2d: layer {public: // create the scenario where the gamelayer layer belongs static cocos2d: Scene * createscene (); Virtual bool Init (); // call this function virtual void onentertransitiondidfinish (); create_func (gamelayer); Public: // update Game Void gameupdate (float DT) based on each frame ); // bullet collision detection bool bulletcollisionenemy (sprite * pbullet); // aircraft collision detection bool enemycollisionplane (); // menu callback function void menuclosecallback (cocos2d: ref * psender ); public: planelayer * planelayer; // aircraft layer bulletsprite * bulletsprite; // bullet layer enemylayer * enemylayer; // enemy layer int getrand (INT start, int end ); // obtain the random number from start to end };

Without too much explanation, let's look at the specific implementation of each function, gamescene. cpp

# Include "gamescene.

There are detailed comments in each key area. You can understand the engine and leave a message if you have any questions.

The download link of the source code is provided. It is hosted on GitHub. the most annoying thing for me is to download something and pay TM credits. For example, share the resources on csdn, I still have to give you some points to download, or you don't need to upload it. Since it is open-source, you don't want to do anything for yourself, and you may need to be sprayed again, but I always believe that open-source is the king, click OK.
