# Ifndef _ helloworld_scene_h __# DEFINE _ helloworld_scene_h __# include "cocos2d. H "using_ns_cc; using namespace STD; Class helloworld: Public cclayer {public: Virtual bool Init (); static ccscene * scene (); create_func (helloworld ); // Add

Thanks for the comments and attention, welcome to reprint and share.Hard work and perseverance. Method One: Cocos2d-x has been packaged for us, and the method is in class Cclabelttf. /** enable or disable shadow for the label * /void

auto root = Dictionary::create(); auto string = String::create("string element value"); root->setObject(string, "string element key"); auto array = Array::create(); auto dictInArray = Dictionary::create();

There are three ways to implement font strokes without regard to effectiveness and efficiency: ① using Cclabelttf to make text strokes and shadow effects ② using Ccrendertexture to render text with a stroke effect ③ is implemented using shader,

Distributed collaboration is indispensable in distributed applications. It usually acts as a coordinator, or isolates the responsibilities of multi-machine collaboration from distributed applications to reduce system coupling and enhance scalability.

This chapter introduces you to two predefined classes in Java: Arrays and strings.Arrays can be divided into one-dimensional arrays, two-dimensional arrays, and multidimensional arrays, depending on the complexity of the elements being stored.

I recently read "headfirst design mode" and found that the difference between simple factory, factory mode, and abstract factory mode is not very easy to understand. After research, I wrote several examples to help me better understand the

About Factory mode and single case mode most of the 2 models are common For example, in an ORM framework, factory patterns are often used to encapsulate the creation of a database, and we'll look at it in 3 different ways. Simple Factory mode
