They are used to name variables and table fields, which will be covered in the chapter about tables. In Lua, as with most other programming languages, the equals sign (=) acts as a dyadic assignment operator assigning the value of the expression of the right hand operand to the variable named by the left operand: The following examples show the use of the equals sign for the assignment of variables: Note that literal strings should be enclosed in quotation marks to distinguish them from variable names: Note that numeric values do not need to be enclosed in quotation marks and cannot be misinterpreted as a variable name, because variable names cannot begin with a numeral: The Lua programming language supports multiple assignments: Identifiers, in Lua, are also called names.

Lua - if statement with two conditions on the same variable? Add a second condition to the if statement to check if raceActive is true before calling finish(). If the condition is true, then Luau executes the code between then and end. In this example, the range is greater than 10 seconds but less than or equal to 20 seconds. Beneath else, use a print statement to prompt them to try again. If the increment is not given, it will be assumed to be 1 by Lua. This is not the case for while loops, which will only execute the code the first time if the condition is actually true. The ipairs() function returns an iterator that iterates through numerical indices in a table and returns an index and value for each element. It ends with the end keyword: When a scope ends, all the variables in it are gotten rid of.
