Parameters, Math, & Returns - Roblox Beginners Scripting Tutorial #7 (2024)

[@VoltigarRBLX]

I've struggled in the past with basic scripting concepts, whether it's because it's hard to pay attention or whatever it may be. I am able to speed up and slow down the videos and your speech is so incredibly consistent and clear that I can always understand what you're saying. All around really fantastic stuff, you have a real talent for explaining concepts just enough to the point where it's understandable without overexplaining or underexplaining. The only thing I think would increase my understanding (this may just be personal preference) is providing real-world/real-game examples (damage calculation, inventory, whatever it may be) of where parameters can come in handy and when it would make sense to apply different arguments to the same function parameters. Aside from that, just really perfect stuff, thanks a lot.

Please don't stop with this series even though your not getting as much views, its grateful to me and to some other people, you've been explaining it perfectly to me and im learning faster than I thought I would! Anyways, some code I made from this video: local function addition(number1, number2) local result = number1 + number2 return result end local printResult = addition(8, 2 ) print(printResult) local function subtraction(number144, number4) local result = number144 - number4 return result end local printResult = subtraction(144, 4 ) print(printResult) local function multiplication(number12, number12) local result = number12 * number12 return result end local printResult = multiplication(12, 12) print(printResult) local function division(number36, number6) local result = number36 / number6 return result end local printResult = division(36, 6) print(printResult) 😅

[@jun-dq9bt]

Return part was confusing asf for me and i believe for some people too but now that i understand it heres a easy way to understanding. For instance, we have local function addition (a, b) local result = a + b return result end local printResult = addition(8,2) print(printResult) If we translate this into english, its like saying "Hey Roblox, when i ask for the result for a + b, you calculate the result and RETURN to me that value. In this scenario, a = 8 and b = 2, find the result of 8 + 2 then RETURN to me that value" So in output you gonna see 10. return : exit a function and pass back a value to the caller.

[@Qvikzz]

whats the difference in saying print(result) then saying return resul

[@thecoalcub6012]

@@QvikzzI'm not an expert scripter or anything but I believe difference is that if you don't return the function it doesn't actually pass a value back to the caller. It's basically the difference between you telling someone a command to do something vs asking that someone a question and getting an answer to it.

[@Suiiro]

@@Qvikzzall printing the result is doing is just printing it into the output (console) for the dev to see, it doesn’t do anything for the game whatsoever. Returning though actually does something with the script itself and its not just visual

[@Life_of_Boredom]

If anyone is still confused on what the return statement is, it’s essentially telling the next line to follow the same perameters and functions (or in a way returning the parameters and functions) which allows him to do a new variable and still have it do the calculations without having to lay out the parameters and telling it how to calculate the numbers again, it’s more of a neat organizing thing which will help your code stay organized. (This is how I interpreted it, someone please correct me if I am wrong.)

[@prozabdielzoo3212]

Omg you just saved me another 1 or 2 days trying to figure this out ty!!!

[@Capy5687]

It took all of my braincells to understand this concept

[@nyanay0]

the next line is "end"

[@liviii4188]

so the return statement lets you use the result of a function elsewhere in your code without repeating the calculations?

[@Contemptical]

i thnk what it does is return tells the function to use the values given without needed to be told if its adding, subtracting etc

[@faintvolley]

It's been slow for me so far, but I feel like I'm starting to really grasp it. This one def had me stumped a lot but I understand it now that I've simplified it for myself. local function addition(number1, number2) local result = number1 + number2 return result end local printResult = addition(8, 2) print(printResult) local function subtraction(number3, number4) local Result = number3 - number4 return Result end local Printresult = subtraction(8,5) print(Printresult) local function multiply(number5, number6) local answer = number5 * number6 return answer end local answerResult = multiply(5,5) print(answerResult)

[@Blood-StrikeGamer]

[@saikonick8312]

most of your vids have the same views, that means that you make ppl be happy to learn coding! Be proud of that!

[@questionmarkdude4910]

i understood pretty quick and the explaination is simple!!! here's my script local function addition(num1, num2) local result = num1 + num2 return result end local function subtraction(num3, num4) local result1 = num3 - num4 return result1 end local function multiplying(num5, num6, num7) local result2 = num5 * num6 * num7 return result2 end local printResult = addition(8, 2) print(printResult) local printResult1 = subtraction(5, 2) print(printResult1) local printResult2 = multiplying(2, 4, 3) print(printResult2)

[@SimplyTutuco]

This is really interesting, but a little confusing. *For what I understood, the return command stores the result of whatever is the function for it to be used again without it having to call the function and calculate it all again. If I'm wrong, please correct me.* Here's what I did for the LO: local function solveSequence(n1, n2, n3, n4, n5) local sequenceResult = n1 * n2 - n3 - n4 + n5 return sequenceResult end local SResult = solveSequence(3, 7, 9, 5, 2) print(SResult) local function epicFunction(epicness, awesomeness) local coolness = epicness + awesomeness return coolness end local totalCoolness = epicFunction(3910, 4927) print(totalCoolness) I understood math, parameters and arguments but somehow couldn't understand returns that well.

[@Demonsinful]

Wdym ,It returns the local function I think you need a dictionary it's literally straight forward.

[@AanybrosS]

So my question is why did u in particular use the word n like wasn’t there any other word

[@GrieferBT]

I will correct you: In order to actually understand returns, you need to realize that function calls (ex: function(n1, n2)) are actually values. The problem is that you actually have to tell the script that the result of the arguments being calculated is the value of said function call. The ‘return’ command does just that. If you don’t put in the return command, the script just runs the function and discards the result after the ‘end’ command is read. Make sense?

i was a bit confused about the part with return but after rewatching it like 3 times i understood it more thanks for the video!

[@korudo855]

you think youd be able to elaborate it?

[@ioproto6581]

​@@korudo855 Here's how I understood it myself; thinking about how we can use the value after we return it. A return is effectively keeping the end value, whereas printing is only telling the console what the value is. For example, if we had a function local function addTwo(X, Y) local result = X + Y print(result) end This is simply just adding two numbers like what the video demonstrated! Say we wanted to run this function twice and print the end result of adding two sets of numbers together. We cannot do a print(addTwo(1,1) + addTwo(2,2)), because we're asking it to add two numbers twice, but we haven't told it to keep the end values of those two individual addition executions we're asking it to do (we tell it to do 1+1, but then just output the result in the console with the 'print' command, and same for the 2+2). We've only told it to print the result. If we return the result, we are asking it to remember the end of the two individual executions of the function. In other words, with the print line above, we've asked it to add 1 + 1, and then print that value. Then, add 2 + 2, and print that value. But then we're asking it to add... what? We haven't asked it to remember that 1 + 1 = 2 and 2 + 2 = 4, so it cannot do what we would expect (2 + 4). Instead, if our addTwo function was this local function addTwo(X, Y) local result = X + Y return result end Now, because of the return, we're asking it to remember its end result upon every execution. So now we can do our print(addTwo(1,1) + addTwo(2,2)) Because now we're telling it to print the end result of (1+1) PLUS (2+2), and it will print 6 as the output in the chat. If this doesn't make sense let me know and I can try to reclarify.

ive tried leaning many coding languages and ive never understood what a return statement was in any of them thank you for explaining really well these are prob the best coding tuts out there function opacity(x,y) baseplate.Transparency = 0.5 wait(1) baseplate.Transparency = 0 wait(1) baseplate.Transparency = 0.5 wait(1) baseplate.Transparency = 1 print(x, y) end i finally understand what a return statement does edit( ) an idea i had with this local function health(health,damage) local res = health - damage return res end local takendamage = health(100,45) print(takendamage) can be used for damage being taken in by a character i dont know if theres a more simple way but this is how i saw it

[@vmc-mal]

Another decent one, here's my learning objective. --No Return local function calcButOnlyAddition(num1, num2) local result = num1 + num2 print(result) end calcButOnlyAddition(100, 100) calcButOnlyAddition(37, 32) --WithReturn local function calcButWithAdditionAndResult(num1, num2) local result = num1 + num2 return result end local result = calcButWithAdditionAndResult(37, 32) print(result) local result = calcButWithAdditionAndResult(100, 100) print(result)

[@H-nl9ub]

man tysm for the guides,this really helps me ur the best! local function addition(number1,number2) local result = number1 + number2 if result == 6 then print("this is equal to 6!") elseif result == 4 then print ("this is equal to 4!") end end addition(2,4) addition(1,3)

[@aaaaaaaaaaaawda]

I used to struggle learning coding, but i learned python and then tried roblox coding again n it was way easier! i kinda already know these basics so im speeding through them but still a great video! . . script: local function addition(num1, num2) local result = num1 + num2 return result end local function subtraction(num1, num2) local result = num1 - num2 return result end local function multiplication(num1, num2) local result = num1 * num2 return result end local function division(num1, num2) local result = num1 / num2 return result end print(addition(2, 4)) print(subtraction(4, 5)) print(multiplication(2, 5)) print(division(5, 2))

[@ump7732]

Thank you for making these, it has made learning scripting easier local function addition(n1, n2) local result = n1 + n2 print(result) return result end local printresult = addition(6, 9) print(printresult) local function subtraction(n3, n4) local result2 = n3 - n4 print(result2) return result2 end subtraction(5, 5)

[@IceyDude1]

i like how you just give us homework but instead of it being really boring you make it feel like i want to do it! Just wanted to point that out😅

[@TarekTRBW]

Agree

[@TarekTRBW]

Attractive homework bro needs to be teacher

[@Imnotbald899]

I'm gona be honest this is the first one I've done the learning objective on just because I can not get my head around what return is used for, it would be great if you could clarify but I'm guessing it's basically just like a loop thing so after the commands before it has finished it'll return to the line it's set at? (a bit bummed that you need all numbers filled out so you couldn't just do 1 + 2 you then had to divide it by something if you used the first script bit like I did) local function addition(number1, number2, number3) local result = number1 + number2 / number3 return result end local printresult = addition(8, 2, 0.5) print(printresult) local printresult = addition(12, 6, 3) local function subtraction(num1, num2) local Sresult = num1 - num2 return Sresult end local sresult = subtraction(1, 4) print(sresult) local function multiply(mul1, mul2) local mresult = mul1 * mul2 return mresult end local mresult = multiply(2, 10) print(mresult) local function divide(d1, d2) local dresult = d1 / d2 return dresult end local dresult = divide(25, 5) print(dresult)

[@Imnotbald899]

I have like 10 hours of coding under my belt though (scratch in school, best thing I mad was cocaine shark that was just a shark that span around violently and slowly moved off the board (I also had never heard of cocaine bear before))

[@MR-VOXELATOR117]

Here is the code i wrote in the last video local functions = game.Workspace.Baseplate local function TrasnparencyTest() functions.Transparency = 1 functions.Transparency = 0.5 functions.Transparency = 0 functions.Transparency = 0.5 functions.Transparency = 1 end TrasnparencyTest() TrasnparencyTest() TrasnparencyTest() local shapes = game.Workspace.ez local function MaterialTest() shapes.Material = "Brick" shapes.Material = "Pebble" shapes.Material = "Rock" end MaterialTest() MaterialTest() local shadows = game.Workspace.ez shadows.CastShadow = falselocal functions = game.Workspace.Baseplate local function TrasnparencyTest() functions.Transparency = 1 functions.Transparency = 0.5 functions.Transparency = 0 functions.Transparency = 0.5 functions.Transparency = 1 end TrasnparencyTest() TrasnparencyTest() TrasnparencyTest() local shapes = game.Workspace.ez local function MaterialTest() shapes.Material = "Brick" shapes.Material = "Pebble" shapes.Material = "Rock" end MaterialTest() MaterialTest() local shadows = game.Workspace.ez shadows.CastShadow = false yay :>

[@erwin-f5b]

i have always loved scripting , i started with java , but i didnt see a future with making games in java. java compared to this is super super complicated , i didnt really belive how simple luau actually is. to be honest i think i had a really big advantage from other people starting with luau since some things are semmilar to java , like funktions and variables. i was always really confused by other youtube videos , since they put stuff that is absolutly not for beginners. i love how you explain pretty much everything , even how to rename the scripts and how to add them every single time xD. Love your videos , dont stop! :]

[@TFS-o8j]

I love how you teach scripting because most people teach scripting real boring so thank you so much and this is what I did! local function plusUltra(number1, number2) local answer = number1 + number2 return answer end local printAnswer = plusUltra(7, 3) print(printAnswer) print("minus") local function minusUltra(number1, number2) local answer = number1 - number2 return answer end local printAnswer = minusUltra(10, 5) print(printAnswer) print("equals 5")

[@tostmakinesi42]

what i did in this episode: local function addition(number1, number2, number3, number4) local result = (number1 + number2) * number3 - number4 return result end local printResult = addition(8, 2, 5, 35) print(printResult)

local function addition(number1, number2) -- Paremeter is basically a variable we only define when calling the function. local result = number1 + number2 return result -- Return is returning whatever the result was too where the function was called, can also stop executions in functions. end local printResult = addition(8, 2) print(printResult) local function substraction(number1, number2) local result = number1 - number2 return result end local printResult = substraction(6, 3) print(printResult)

[@ushouston633]

i wasnt as cool in mine, but i took alot of notes local function addition(number1, number2, number3) --[inside parenthesis are our parameters] local result = number1 + number2 - number3 return result end -- return statements return the value local printResult = addition(10, 20, 15) -- adds variable to number1, number2 by using "addition()" print(printResult) -- print actually executes the command --[[ difference in arguments and parameters are that parameters are what we use to create our variables inside of the parenthesis (function caluclation) and the stuff below is the calcuations the argument is what values we throw into the function]]

Thanks :D I will do special thanks you in my experience :D

[@susguy_yk7430]

Hey! I don't know if anyone here is active since these videos was posted 5 months ago.. But I'd like to tell the people that are also learning Lua script codelanguage (Just like me) that if u sit and stare at a code and try to understand what all the yapping and words are for and what they mean. Copy or write down the code on your pc and paste it on ChatGPT and ask the robot what all the words are telling you or what they do! This helped me ALOT. Make sure (only if u need) to ask the Bot to adapt the language to the way only YOU understand it so it gets easier! That also really helped me as i got language disorder and adhd. But take care guys i love helping (if this even helped or did i just yap for nothing😭🙏🏽)

[@Lilisa33]

can I ask, whats the point of the "return" command, when it seems like it didnt really do anything to the code?

[@SaimonasMartinkus]

we need more people like you :) local function multiply(num1, num2, num3, num4) local multynum1andnum2 = num1 * num2 print(multynum1andnum2) local divinum1andnum2 = num3 / num4 print(divinum1andnum2) end multiply(4, 12, 86, 3)

Knowing the first certified course of Python, we can add (moreover, concatenate) two strings in lua too! ... additions("5" + "2") which in the output, will show 52 as they cannot handle plus operation. Butm they can handle multiplication. additions("5" * "2") = 10

here's a simplified version of the code BrawlDev wrote in this episode: local function addition(number1, number2) return number1 + number2 end print(addition(8, 2))

[@gapperss]

Btw if ur struggling to figure out how to multiply and divide the symbol for multiplication is * so number1 * number2 would mulply both number and if for division it would be a front slash / so num1 / num2 to divide num2 from the first number subtraction is a dash (-) incase u forgot
