This control structure is called a count-controlled loop, and, in Lua and most languages, is defined by the for statement. The difference between while and repeat loops is that repeat loops will check the condition at the end of the loop while while loops will check it at the start of the loop. Control structures are statements that manage the flow of Luau code execution. What is the point of Thrower's Bandolier? @MateusNunes: You should probably convert your text (known as a "string") to a number. If a condition is true then Logical NOT operator will make false. print("Voila !, Rahul age is 5" ) print("Age of mine, 5 years ago was :", Agenew ) This is because one side is evaluated before the other side, so in left-to-right order it ends up going from x < y < z to true < z which is an error, whereas in the explicit method, it goes from x < y AND y < z to true AND y < z to true AND true, to true. Otherwise, they return the boolean value false. The repeatuntil loop repeats until a condition is true. Connect and share knowledge within a single location that is structured and easy to search.

This is because one side is evaluated before the other side, so in left-to-right order it ends up going from x < y < z to true < z which is an error, whereas in the explicit method, it goes from x < y AND y < z to true AND y < z to true AND true, to true. In some cases, the approximation will match the number exactly, but in some cases, it will only be an approximation. IF with multiple AND & OR statements If your task requires evaluating several sets of multiple conditions, you will have to utilize both AND & OR functions at a time. then They can be used to access a number later after storing it in the memory.

So it looks like: I plan the system to register when a Humanoid is touched, and if the part is going faster than say, 300 Studs per second, I want it to play an audio (preferably the audio would be played only for the person(s) that was touched by the part) so I wrote a script that goes as follows: As you can see I'm missing the part about the humanoid being touched, but I'm not sure how to write that. You can probably already see how this would be helpful in creating 'if' statements with more complex conditions.

If the increment is negative, then the process repeats until the counter is equal to or less than the end value.
