lua c scripts

In addition to an extended speech, Lua is also a "glue language ". The most famous is game Script Development. Here we mainly talk about how Lua interacts with C. The main method for communication between Lua and C is an ubiquitous virtual stack. Almost all API calls will operate on the value on this stack. All data exchanges, from

Label: style blog HTTP Io color OS ar sp Lua is a language with excellent scalability. Although its core is very simple, you can rely on the Lua library for most of the work. In addition, Lua can also expand program functions by calling each other with C functions. Embedding a Lua script in C allows you to modify the

New DLL empty Win32 project, new Test.cpp file, the content is as follows/*lua call C + + functions/libraries (dynamic link mode) */#include Lualoadlib.lua file--region lualoadlib.lualocal libpath= "./. /debug/luaapidll.dll "Local loadlibfunc=package.loadlib (Libpath," Luaapidll ") Loadlibfunc () function COS (a) Print ("Called COS in Lua script") return Dy_math.cos (a) endfunction sin (a) print ("

Last time I learned how to use C to call Lua's function and return a result, this time look at how to use Lua to invoke C's function.I. INTRODUCTIONC Call LUA function is relatively simple, only need to manipulate the relevant stack on it, but Lua calls C, a little bit of trouble, although still with the stack to carry out the data, but because

I studied Python a few days ago and was deeply attracted by her simplicity and efficiency. Today, when I watched cloud wind's "game journey-my programming sentiment", I saw that he highly praised Lua and brought it down for fun at night-BTW, for friends who are interested in game development, we recommend those days of the cloud wind-talking nonsense. Let's get started... 1. Download source code, http://www.lua.org/ftp/

In the vs project, use c ++ to call lua and lua to call c In the previous article, we have discussed how to compile lua source code and generate lua. lib (please refer to use vs2010 to compile lua5.1 source code to generate lua. lib), in the new project, we continue to use t

The method for parsing Lua scripts in Unity3d, and unity3d for parsing lua scripts Because the project has been proposed recentlyHot updateSo I spent the weekend with Lua. The combination of Lua and Unity3d only reaches a glimpse of the door path. The level is limited. You are welcome to correct your criticism. There

I don't know where csdn has taken note 2. It was written for 2nd times. Lua study Note 2Use your own c Functions in Lua Okay. The last time we learned how to write a function in the Lua script and apply it to the C file.Now let's learn another interaction method. Purpose of this section: to call a self-written function in a

Cocos2d-x Open Source engine is currently very popular in the field of mobile development, I used for a while, very like its Lua binding, Once understood its working mechanism, compared with C ++. However, it is not easy to use the Lua script. To make Lua binding very easy to use, it may still require a lot of work. Record a very practical technique here: When

Prepare cocos2dx lua, and compress lua for reference. (I am also a little confused. If you find anything inappropriate, please try your best. I accept all) 1. Version: This is a pitfall. First of all, pil (programming in lua) Chinese (it seems to be a great success) translation version is 5.0 a little low. Cocos2dx 2.15 uses

Lua is a small scripting language. It has the advantages of being lightweight and extensible. It can be used as a powerful, lightweight scripting language for any program that needs it.LWT (LUA Web Tools) enables you to use LUA to develop Web applications and to run directly on Apache. LWT's core functionality is provided through an Apache module (MOD_LWT). In ad

A, Lua execution string There is a problem during the run, I have a string, is a mathematical expression, how to calculate the value of this string expression?For example, the local param = "7*100", I need the result is actually 700, but how to calculate this value directly? Methods are as follows Prefix the string with a "return"Then LoadString gets a function later.Then perform a return value of 700, so that by converting, the results are as fol

It's been half a month since I wrote a LUA article, and it's time to refresh your LUA state. This tutorial will introduce the LUA stack and basic stack operations, as well as how to read the LUA table in C + + code. Understanding the LUA Stack

1. Lua is written through ANSI C, and LUA interacts with C to follow certain protocol rules. The LUA 5.1 Reference manual explicitly stipulates how the functions written by Lua are called by C code. C code can invoke any function written by LUA code. This article mainly take

Q: What is "Registry"?A: Sometimes we need to use some non-local variables in our program. In c we can use global variables or static variables, and in the process of writing C libraries for Lua, using variables of the above type is not a good way. First, the values of LUA cannot be stored in these variables. Second, these variables are likely to cause unintended results if they are used in multiple

C ++ calls Lua and lua Reprinted please indicate the source: http://blog.csdn.net/zhy_cheng/article/details/39756423 The cocos2d-x version I use is 2.3.3, first configuring the lua environment in a C ++ project.

As a network game, it is inevitable to interact with the server, the data structure on the PROTOBUF is a good solution, the use of protobuf in Lua there are a variety of options, where the use of the cloud wind of the PBC. First go to this web site to download the build tool http://repo1.maven.org/maven2/com/google/protobuf/protoc/, my side of the download of version 2.5. Put the Protoc.exe in the designated place, and then copy the proto file, for be

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 LUA
