Lua was originally designed in as a language for extending software applications to meet the increasing demand for customization at the time. It provided the basic facilities of most procedural programming languages, but more complicated or domain-specific features were not included; rather, it included mechanisms for extending the language, allowing programmers to implement such features.
As Lua was intended to be a general embeddable extension language, the designers of Lua focused on improving its speedportabilityextensibility, and ease-of-use in development.
From untilBrazil had a policy of strong trade barriers called a market reserve for computer hardware and software. In that atmosphere, Tecgraf's clients could not afford, either politically or financially, to buy customized software from abroad.
Those reasons led Tecgraf to implement the basic tools it needed from scratch. There was a lack of any flow-control structures in SOL and DEL, and Petrobras felt a growing need to add full programming power to them.
In The Evolution of Luathe language's authors wrote: . Inthe only real contender was Tclwhich had been explicitly designed to be embedded into applications. However, Tcl had unfamiliar syntax, did not offer good support for data description, and ran only on Unix platforms. Python was still in its infancy. In the free, do-it-yourself atmosphere that then reigned in Tecgraf, it was quite natural that we should try to develop our own scripting language Because many potential users of the language were not professional programmers, the language should avoid cryptic syntax and semantics.
The implementation of the new language should be highly portable, because Tecgraf's clients had a very diverse collection of computer platforms. Finally, since we expected that other Tecgraf products would also need to embed a scripting language, the new language should follow the example of SOL and be provided as a library with a C API.
Lua 1. In an article published in Dr. Dobb's JournalLua's creators also state that LISP and Scheme with their single, ubiquitous data-structure mechanism the list were a major influence on their decision to develop the table as the primary data structure of Lua. Lua semantics have been increasingly influenced by Scheme over time,  especially with the introduction of anonymous functions and full lexical scoping. Several features were added in new Lua versions. Versions of Lua prior to version 5.
From version 5. Both are permissive free software licences and are almost identical. Lua is commonly described as a " multi-paradigm " language, providing a small set of general features that can be extended to fit different problem types. Lua does not contain explicit support for inheritancebut allows it to be implemented with metatables.Lan to wan subnet
Similarly, Lua allows programmers to implement namespacesclassesand other related features using its single table implementation; first-class functions allow the employment of many techniques from functional programming ; and full lexical scoping allows fine-grained information hiding to enforce the principle of least privilege.
In general, Lua strives to provide simple, flexible meta-features that can be extended as needed, rather than supply a feature-set specific to one programming paradigm.
Lua is a dynamically typed language intended for use as an extension or scripting language and is compact enough to fit on a variety of host platforms. It supports only a small number of atomic data structures such as boolean values, numbers double-precision floating point and bit integers by defaultand strings.

Scripting is a programming abstraction in which you conceptually have a program the script running inside another program the host.Collisions and Vectors - Recreating Zelda
In most cases, the language in which you write the script is different from the language in which the host is written, but any program-inside-a-program abstraction could be considered scripting. Conceptually, the common steps to enable scripting are the following I will be using pseudo-c for the host and pseudo-lua for the script.
These are not exact steps, but more like the general flow in which you enable scripting. Notice that the name in which we exposed the function print does not have to match the internal name of the function itself scriptPrintMessage. You call doText. Control is then transferred to the virtual machine, which will execute the text inside scriptCode.
The script code finds a previously exported symbol print. It will then transfer control to the function scriptPrintMessage.
When scriptPrintMessage finishes, control will transfer back to the virtual machine. When all of the text in scriptCode has been executed, doText will finish, and control will be transferred back to your program on the line after doText.
So in general, all you're doing is running a program inside another program. Theoretically speaking, there is nothing you can do with scripts that you can't do without them, but this abstraction allows you to do some interesting things really easily. Some of them are:. Done right, the game code can be developed completely independently from the engine itself. Flexibility: scripting languages are commonly interpreted, and as such, a change in a script will not necessarily require a rebuild of the entire project.
Done right, you can even change a script and see the results without even a program restart!Medical business plan pdf
Stability and security: since the script is running inside a virtual machine, if done right, a buggy script won't crash the host program.
This is specially important when you allow your users to write their own scripts to your game. Do remember that you can create as many independent virtual machines as you like! I once created an MMO server in which each match ran on a separate lua virtual machine.Miglior prezzo lacompatibile lavazza a modo mio(r)
Language features: when using scripting languages, based on your choice for host and script languages, you can make use of the best features each language has to offer. Debugging becomes very difficult: usually, the debuggers included in common IDEs are not designed to debug the code inside scripts.
Because of this, console trace debugging is much more common than I'd like. Some scripting languages like lua have debugging facilities which can be taken advantage of in some IDEs like Eclipse.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Game Development Stack Exchange is a question and answer site for professional and independent game developers. It only takes a minute to sign up. Lua is a pretty well developed scripting engine that is flexible and easy to integrate to your games, and is already supported in many game engines, for instance:. The portions of a game written in scripting languages can be modified while the game is running, without having to restart or recompile.
This is important if the people working on the scripted portions don't have access to the compilation tools, or if compilation takes a long time. Sign up to join this community. The best answers are voted up and rise to the top.
