Cocos2d-x v3.2 flappybird Specific code analysis for each class object (6)

Today we are going to talk about three classes, these three classes should be fairly simple

Helplayer class

Numberlayer class

Getlocalscore class

Helplayer class, mainly put two graphics elves up, one is the name of the game, a hint game how to play, on a picture:

Numberlayer class, related to the production of custom fonts, we extracted resources, there are many digital pictures:

And now we're going to make them like this:

This is similar to the game picture resources, made so that you can directly take to use, save a lot of things, that how to do, here we need to use a called software, the specific use of methods and processes, I do not introduce here, we directly poke here

The introduction is very detailed, but also thanks to this author. Numberlayer class There is another problem in this class is a singleton implementation, Singleton class: As the name implies it has only one instance, sometimes a function class has a lot of instances, will make the program become very complex, the Singleton class solves the problem.

Getlocalscore class, local data access, this class is also very simple, are called, cocos2d-x some of the interface, so there is no difficulty.

Here is the code analysis for these three classes:

We'll be here today.
