In this NEW 2024 Guide to Roblox Scripting for Beginner Developers, I will go through everything you need to know to continue scripting on Roblox!
My new mission is to have fun teaching everything I know from developing games on Roblox since 2016. We will dive into scripting concepts as basic as printing to as complicated as raycasting. For every episode of this series, I encourage you to do everything I do to gain experience and let it stick with you so that you can create the games you're passionate about on your own. Enjoy this series and remember: being a competent scripter takes time and effort so don't get discouraged if things get too tricky. Remember where your inspirations came from; if you can be a Roblox scripter, then anyone can!

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.

i made it so that if the print result is not equal to 4 it prints "AAAAAA" and if it is it just prints the result, which is 4 pretty useless tbh because there's really no point in printing the correct result because whatever you set the result to will always be equal to itself.

[@RSM_ONION]

My interpretation of the return command local function addition(number1, number2) local result= number1 + number2 return (result) end local printResult = addition(8, 2) print (printResult) in this example number1=8 and number2=2 8+2=10 result=10 return result is basically just sending result back in place for the "addition(8,2) so local printResult = 10 therefore print (printResult) prints "10"

[@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)

[@daniel_denamit724]

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.

[@BruhEditsFr]

@@korudo855 Basically return is returning values. For example: I give 5$ for a burger in return I get a burger. Read this 4 times and u should get it.

[@sereneybeanie6733]

I was having a hard time with parameters and return statements for a while now and this helped me understand at least a little more so thank you! Here's what I did for the learning objective btw: local function subtraction(number1, number2) local result = number1 - number2 return result end local printSResult = subtraction(2, 1) print("Subtraction result: ", printSResult) local function multiplication(number1, number2) local result = number1 * number2 return result end local printMResult = multiplication(8, 2) print("Multiplication result: ", printMResult) local function division(number1, number2) local result = number1 / number2 return result end local printDResult = division(5, 2) print("Division result: ", printDResult)

[@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.

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

[@V4x07]

here's mine which i tried to do, first i tried: ''if hp < 1 then print('You died') end'' and it told me that i cant compare hp to a number because is a ''nil'', so i stood there in front of my screen, during like 10 mins thinking what to put, and i magically thought of replacing ''hp'' for ''hpLeft'', and it worked. Let me know if the script is okay, ik it most likely isnt the best option for a damage and hp system for a fighting game but im a beginner and i wanna know if i did good so far with this attempt, here's the script: local function critHit(hp, dmgtaken) local TotalDmg = hp - dmgtaken return TotalDmg end local hpLeft = critHit(50, 60) if hpLeft < 1 then print("You died") end

[@Sk_lled]

Yeah, I'm just starting this and I've done basic python and know most of this

[@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

[@RNC-o6u]

This helped a lot, this is what I got for my code: local function Division(num1, num2, num3) local result = (num1 / num2) + num3 return result end local printResult = Division(8, 2, 4) print(printResult) local function Subtraction(num10, num9, num8, num7) local answer = (num10 - num9 - num8) / num7 return answer end local AnswerResult = Subtraction(8, 2, 4, 2) print(AnswerResult)

Thanks again, here's the script I made, i know its not much but i tried local function subtraction(number1, number2, number3) local result = number1 - number2 - number3 return result end local printResult = subtraction(100, 50, 25) print(printResult) Outcome = 25

Yo I was just gonna say this map concept is really cool and all these concepts are sick. But I was just gonna ask of what the practical use for math would be inside of our scripts?

[@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

that's adds all of the things that learm in the video ;) local function addition (number1, number2) local resultAddition = number1 + number2 return resultAddition end local printresultaddition = addition(2, 1) --for example print(printresultaddition) local function multiplication (number1, number2) local resultmultiplication = number1 * number2 print(resultmultiplication) end multiplication(2, 1)

this one was definetly the hardest one so far, heres what i did (its not much ik but it was hard to understand it all in a few minutes): local function addition(number1, number2, number3, number4) local result = number1 + number2 / number3 * number4 return result end local PrintResult = addition(8, 2, 2, 5) print (PrintResult)

[@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)

heres what i did! i stopped for a day but im back on my scripting grind, btwdo i always have to use returns when i do something like this? local function add(number1, number2, number3) local result = number1 + number2 + number3 return result end local printresult = add(50, 45, 10) print(printresult) local function sub(number1, number2) local result = number1 - number2 return result end local printresult = sub(12, 2) print(printresult) local function mul(number1, number2) local result = number1 * number2 return result end local printresult = mul(5, 10) print(printresult) local function div(number1, number2) local result = number1 / number2 return result end local printresult = div(10, 2) print(printresult)

[@marwanatta]

Your explanation is fantastic, but I couldn't understand what is the return statement. Is it an alternative to the print statements? and also if I use it in a function and then write a bunch of lines in the same function under it, they won't run will they? pls answer my question cause I think I wouldn't be able to go further like that

[@LaufzDS]

great videos, i learnt alot and still learning!

[@GaijenParadox]

The Return statement kinda got me confused on its use but I figured it out by interpreting the function as a power plant, with the return statement you send off the power to where it being called and you can use it for different things, printing etc. hope this helps anyone else confused

[@jellyioup]

So it returns it to the part of the code thats being called and can be used outside of just printing? I'm so confused lol

[@Ben0xT]

i just started coding and you videos helped me alot thank you local function additon(numb1, numb2, numb3, numb4) local result = numb1 + numb2 + numb3 / numb4 return result end local superadditon = additon(3, 7, 3, 5) print(superadditon)

local function addition(number1,number2) local result1 = number1 + number2 return result1 end local printresult1 = addition(2,9)--result 1 is turned into a variable with a function when u use return on it local function subtration(printresult1,num2) local result2 = printresult1 - num2 return result2 end local finalresult = subtration(printresult1,10) print(finalresult)-- using that same variable I used it as a secondary number for result 2

this video was great but i needed my dad to explain what returns were cause prob just for me i didnt know what it was i just knew that it did smt like when i was using returns i didnt understand it took a lot of raging to understand this lol (but thats prob just for me) but dont be sad if you somehow see this because i have spent money on trying to learn but you are showing people how to do it in an understandable way the only thing i can say that is bad is that u get ahead of me while i type but thats not a big problem cause everyone can just pause
