Did this satellite streak past the Hubble Space Telescope so close that it was out of focus? repeat block until exp1 Each function (including the main thread, the core of the program, which is also a function) also has its own environment, which is a table that uses indices for the variable names and stores the values of these variables in the values that correspond to these indices. Overview: 1.The Lua flow control statement is set by programmatically setting one or more conditional statements.Executes the specified code when the condition is true, and any other specified code when the condition is false. if( RahulAge == 0 ) Infinite loops can take a lot of computer resources, so it is important to make sure that loops will always end even if unexpected input is received from the user. The Lua if statement takes a condition and a block of statements, and executes the statements only if the condition is true: if score >= 1000 then print ("you win!") score = 0 end.

Lua - if statement with two conditions on the same variable. 2023 Roblox Corporation. The code above also demonstrates how the and keyword can be used to combine many boolean expressions in a conditional expression. It is also possible to execute a certain piece of code only if the expression was not true by using the else keyword and to chain conditional statements with the elseif keyword: Note that the else block must always be the last one. Students also viewed. Statements are pieces of code that can be executed and that contain an instruction and expressions to use with it. I know how to limit it to one: =if ( [Color]='Blue', [Color]) That can not be the case in LUA right? If the player didn't earn any of the medals, you should encourage them to try again.

Some statements will also contain code inside of themselves that may, for example, be run under certain conditions. end Like many languages, any Lua value can appear in a condition. They are created exactly in the same way as global variables, but they must be prefixed with the local keyword.

When there are two conditions in an IF statement with the AND operator, does Lua read left to right and stop as soon as it reaches one false? Because dofile does not run in protected mode, all errors in chunks executed through it will propagate. A while loop executes code only if a specified condition is true, and repeats execution while the condition remains true. The third parameter of the load function can be used to set the environment of the generated function and the fourth parameter controls whether the chunk can be in text or binary. Assignments are performed as if they were really simultaneous, which means you can assign at the same time a value to a variable and to a table field indexed with that variables value before it is assigned a new value.
