What is the language of Cocos2d? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Cocos2d is implemented by C++, and C++ is the inheritance of C language. This language can not only carry out procedural programming of C language, but also object-based programming characterized by abstract data types, and can also carry out object-oriented programming characterized by inheritance and polymorphism.

Characteristics of C++

Support for data encapsulation and data hiding

In C++, the class is the tool that supports data encapsulation, and the object is the implementation of data encapsulation. C++ supports data encapsulation and data hiding by establishing user-defined classes.

In object-oriented programming, data and functions that operate legally on the data are encapsulated as the definition of a class. Object is described as a variable with a given class. The object of each given class contains several private, public, and protected members specified by the class. Once a well-defined class is established, it can be regarded as a fully encapsulated entity and can be used as a whole unit. The actual internal work of the class is hidden, and users using a well-defined class do not need to know how the class works, as long as they know how to use it.

Support for inheritance and reuse

New types can be declared on the basis of existing classes in C++, which is the idea of inheritance and reuse. Through inheritance and reuse, we can organize the program structure more effectively, clarify the relationship between classes, and make full use of existing classes to complete more complex and in-depth development. The newly defined class is a subclass and becomes a derived class. It can inherit all non-private properties and methods from the parent class as its own members.

Support polymorphism

Use polymorphism to specify expressive behavior for each class. Polymorphism forms a tree structure consisting of parents and their subclasses. Each subclass in this tree can receive one or more messages with the same name. When a message is received by an object of a class in the tree, the object dynamically determines some usage of the message given to the subclass object. This feature of polymorphism allows the use of high-level abstractions.

The combination of inheritance and polymorphism can easily produce a series of similar but unique objects. Because of inheritance, these objects share many similar features. Because of polymorphism, one object can have a unique way of expression, while another object has another way of expression.
