lua coding classes

There is no concept of a class in Lua, but we can use the language features of Lua itself to implement classes. The following detail explains the principles of implementing classes in Lua, the details to be split, and the students who believe that the understanding of the i

Refer to the self-built. This article records how to build the best coding environment for Lua scripts in the MAC system environment with powerful Code Completion and compilation and running. The sublime text editor is used here. The following describes in detail: (1) download sublime text Note that the version is 2.0.2 and sublime text 2. (2) install the Lua e

See "How quick-cocos2d-x 3.3 binds custom classes to LUA II" in the new project, we have completed the environment required for binding in our new project, and the next most critical step. Binds custom C + + classes to Lua. In fact, in order to facilitate our response to different platforms, the engine has helped us cr

The words are connected to the article. After successfully configuring Qt+lua+tolua, we can implement classes that use each QT in a Lua script. Look directly at the code.#include "include/lua.hpp" #include The author writes several functions of qwidget into the form of static and binds them with Tolua. This makes it possible to use a bound function smoothly in a

the COCOS2D-X environment, such as memory recycling, so Cocos2d-x has given up the tolua++ from 3.x. and. Pkg instead of using their own bindings-generator scripts is a very commendable clever practice. Next, how to use the Bindings-generator script: 1, write their own C + + class, according to Cocos2d-x rules, inherit the Cocos2d::ref class, in order to use the Cocos2d-x memory recovery mechanism. 2. Write an. ini file so that bindings-generator can tell how the C + + class is exposed based

I wrote a method to export the class to Lua using the tool 3.0 to automatically generate code.In the past, to export the C ++ class to Lua, you had to manually maintain the PKG file, which is a nightmare. After 3.0, you will feel that life is easy.Next I will discuss the specific practices.1. Install the necessary libraries and toolkit, and configure the relevant environment variables, please follow the coc

Since we did not change the build path of the intermediate file in the Python file, it should be in the same directory as the Lua_cocosdx_auto.Register our custom classes and add code to the AppDelegate.cpp file:This a

binding is no longer added to the "LuaCocos2d.cpp" here, but a separate generation of a new, only our own binding class interface of a class to put into the project.

Overview A class is like a stencil that creates objects, and for Lua, a language with no class concept, the way to simulate classes is to develop a prototype (prototype) for the object to be created. This prototype corresponds to a class in another language. But the prototype is also a regular object, and when other objects (as examples of prototypes) encounter an unknown operation, they look in the protot
