#Gideros return multiple variables code#

Returns a formatted version of its variable number of arguments following the description given in its first argument (which must be a string). If it finds a match, then find returns the indices of s where this occurrence starts and ends otherwise, it returns nil Looks for the first match of pattern in the string s. The default value for i is 1 the default value for j is i. Returns the internal numerical codes of the characters s, s, Have a look at them, and then study the examples below. The following table gives an overview of string manipulation commands. Note that the string library assumes one-byte character encoding. Unlike C, the first character of a string has an index of 1 by default. Lua has a powerful set of string manipulation functions, such as finding and extracting substrings. Try the function above, this time with values 4,5,5.

#Gideros return multiple variables code#

LetвЂ™s start with the simplest Lua code which is printing to the console:ДЇunction calculate ( w, d, h ) if h > 4 then print ( 'The height of the room cannot be more than 4.' ) return end volume = w * d * h return volume end - calling the function to calculate the volume of the room print ( calculate ( 4, 3, 4 ) ) Gideros Studio, with Lua, produces fast and lightweight applications and games.Дespite the size of the Lua interpreter (about 150Kb in size), Lua is very rich and can be extended. In Gideros Studio, you usually write your code in Lua however, you can also extend your applications with other languages like Objective-C, C++, C or Java.

Lua is mentioned as the fastest language among all interpreted scripting languages. The advantages of Lua are its simplicity and its speed. Lua is used in commercial applications, including Adobe's Photoshop Lightroom, World of Warcraft, Far Cry, Garry's Mod, Supreme Commander and Sonic the Hedgehog.

Lua was created in 1993 by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes, members of the Computer Graphics Technology Group at PUC-Rio, the Pontifical University of Rio de Janeiro.
