You can probably already see how this would be helpful in creating 'if' statements with more complex conditions. The do statement will be used to describe them. Then, a conditional statement checks if the value stored in the variable number is smaller than ten, which is the case here. 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. But you can achieve it by nesting. if( Age == 5 ) Now, if the if the statement is true then the program will complete the if operation and will output the result specified for the true condition. If the condition is true, then Luau executes the code in the loop and repeats the process. 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. The syntax of an if.else statement in Lua programming language is if (boolean_expression) then -- [ statement (s) will execute if the boolean expression is true --] else -- [ statement (s) will execute if the boolean expression is false --] end The second parameter of the load function is used to set the source of the chunk. Multiple IF Conditions in Excel - How to Use? (Easy Steps) - WallStreetMojo They are created exactly in the same way as global variables, but they must be prefixed with the local keyword. Often used for this purpose, Lua can be found in everything from photo editing applications to used as an internal scripting language of video games like World of Warcraft.

Here is a brief overview of some of the basic syntax used in Lua: Comments are preceded by two dashes (-). (A and B) is false. Variables are references to a value which is stored in the computer's memory. This makes if statements easier to read for coders, and also reduces the changes of errors. If a condition is true then Logical NOT operator will make false. Called Logical OR Operator. Renderers, software processes that draw things on the screen, for example, will often loop constantly to redraw the screen to update the image that is shown to the user. sc; Non-conventional commands include table constructors, explained in Section 4.5.7 , and local variable declarations.

The ipairs() function returns an iterator that iterates through numerical indices in a table and returns an index and value for each element. The first parameter is the name of the file from which to get the code. In practice, only local variables should be used because they can be defined and accessed faster than global variables, since they are stored in registers instead of being stored in the environment of the current function, like global variables. What's the scope of a variable initialized in an if statement? end To finish, you'll use an if statement with multiple conditions that will award a different prize medal to players based off their performance. You can either display the time on a part using a Surface GUI, like in the, humanoid = character:FindFirstChildWhichIsA(, -- Runs whenever the player touches the finish line part, -- Used to keep finish() and timer from repeating when race is over, -- Runs when the player touches the finish line and shows them an award, -- Checks if a player touches the part when a race is active.
