Remote Functions (Two-Way Communication) - Roblox Advanced Scripting #6 (2023)

[@Likeable_Emmec]

Wow. Honestly impressed with how you explained things here! I'm a little rusty on the RemoteFunction since it doesn't have too much scenarios I use in my games, so having a tutorial as in-depth as this is really helpful. Keep up the great work!

[@BrawlDevRBLX]

I'm glad to hear that! It seems like people find it less interesting for in-depth explanations and want to get straight to the answer of implementation. I've been debating about this, but I think what I'm doing is really helpful for a bunch of people who want to understand these concepts in greater detail and I don't have to give that up just to be more appealing to the general audience. I hope you continue to find my videos helpful, even if they are explained pretty long! 😅

[@savipott]

@@BrawlDevRBLX i personally don't think I would be able to understand this without the long explanation... If anything, the length just gives you more time to really get in-depth with the matter at hand, and since it's quite a complicated subject, the more material the better!!! P.S i'm really happy with the progress I've been making in scripting due to you!! cheers on 21k!!!!

[@momomon7662]

That challenge at the end was so hard, I spent well over an hour (I think almost two hours) writing it, testing it, fixing the bugs, testing it again, searching up errors that popped up in the output and then fixing it again, it was SO SO SO much fun, even though I did get frustrated just staring at the code trying to think of anything else that I could possibly do that could fix the code, but the satisfaction at the end after debugging everything myself and staring at the screen trying to think of anything I could do to change the code so that it works, I cannot explain how happy I am with myself after that challenge. I owe you so much.

if yes, what about returns?

[@owlzam612]

@@patpace idek what return end does 😭

[@patpace]

@@owlzam612 return delivers and stores a value back to the function. Simple as it gets.

[@Project_Ares01]

@@owlzam612 It basically gives the value contained in the variable. in the video, the variable PurchaseSuccessful = true which means that the variable PurchaseSuccessful contains the boolean value - true when it's called to return, the variable contains the value which is true so when they checked if the PurchaseSuccessful == true then it's indeed - true

[@the4thmuffin874]

ive never seen a more in-depth scripting guide than yours. I've watched the beginner scripting tutorial and planning to watch all of the advanced scripting. You are the best youtuber for learning how to code

[@pr0doxz410]

You know it’s a good day when BrawlDev uploades!!

[@Averist]

I have been learning developing for a year now. So i already have some knowledge on this. You make everything seem easier for me thank you. Ans and also guys developing is not something you learn in a week or a month it takes a lot of time. Even big developers dont know everything on developing. Just KEEP LEARNING AND PRACTICING. I hope you find this comment useful.❤

[@ItzBlixYT]

Thanks so much for a series like this BrawlDev! The challenges are a fun part to do

[@TackJum]

Honestly I wish you could just get picked up by the algorithm already cause these are actually useful

[@kosmosaurus]

I've been reading some scripting books and when I got to the Remote Functions chapter, I never understood it. Now I can make a whole shop without looking at anything for help! The challenge was really fun, not too hard, and I didn't even have any bugs! Thanks so much (again)!

[@joncepearce7293]

This tutorial was much more helpful and direct than any other videos I've seen without being confusing. This deserves more views

[@Boomboomboy-j6x]

Thanks man, I was wanting to make a Roblox game and I thought I was a downer at scripting because I couldn’t find anyone who did a beginners tutorial so thanks man 👍🏼

[@Project_Ares01]

That was a really fun challenge. (probably because I succeeded) Although I didn't approach it the same way that you did because I lack experience on using variables, parameters, and tables (I also created individual remote events for each call too). I ended up repeating myself many times and it felt tedious and boring. but in the end, I succeeded, and I was happy for myself. The excitement from succeeding on the challenge didn't last long as I watched you code the same thing but taking 1/5 of the time it took me to make while not even using tables😅. But then I remember that I shouldn't be comparing myself to someone who has a lot more experience and knowledge, instead, take the comparison as a lesson to learn about my lack of knowledge and skills, therefore allowing me to grow even more. Your tutorials actually teach us how to program not just what to program. Anyway again, thank you for all the tutorials, it's awesome!

[@CodeByteCrafter]

at first i was rlly confused with both events and functions, After watching for 2-3 times and practising different things i can confirm that remote events and functions are not hard or easy and rlly useful. once again tysm for these turtorials!!!❤

[@agoobaka]

You seriously need some more attention. Like, the way you teach (like the intro explanation) is very easy to understand. The challenges you also do are very helpful as to remember the other things and such. When I'm done with this series i can give you more feedback. Anyways, thanks for making good tutorials.

[@TheAndrey1]

Hey! It took me 3 days to understand remote functions and remote events at least, it was pretty hard to get everything you need about these topics, and it took me over 1.5 hours to make the last challenge shop system!, Thank you very much for making these videos, i learned a lot!!!

hi im watching this as a beginner trying to learn how to script for freelancing, i love your videos keep doing them PLEASE their extremely helpful and have a touch that no other tutorials have. i think i would 1000% watch you script with you just talking about anything really, as those videos although seem boring would really be entertaining imo

[@realsuperjuice]

you are so good at explaining!

[@baconheadhair6938]

0:51 ive just used remote events to do that, you can just fire server then fire the client in the fire server functions and it works the same

[@miso9292]

challenge at the end had my script looking so messy, unfortunately had to look at the video to follow through with it, just a few errors on my script which totally messed it up, but I'm taking it as a learning moment! scripting involves so much trial and error i have to get used to it

[@onlyAJ2]

your videos helped me alot with scripting!

[@MultiplyMaster]

Really good tutorial :D btw how did you make the icons in explorer look like that?

[@F1R3CPU]

About the challenge what I did is put the tools in replicated storage and I didn't any arguments on InvokeServer (I scripted each function separately) and the Clone() I did it on the local script inside the shop GUI and it worked. I don't know if I did correct or it is better the method shown in the video

[@queijoqualhofanaf]

For the challenge, you can simply make the entire mousebuttonclick section a function and write local player = game.Players.LocalPlayer soo it knows which player's backpack the tool should be put

I finished the begginer scripting tutorial today.

[@ThatGuyNamedBender]

Pre-video comment before I watch as I am curious if it will make what I did easier lol So I handled security for these interations between server and client using events and a profilestore Within the profile store I have a key for each player going security -> actionHash In my server script I handle an interaction event with a proximity prompt that then creates a sha256 encrypted key based on several factors which I can't reveal but then that hash gets stored to the player's security.actionHash data then I fire a client event to handle gui and animations but I send that hash to the client, then when that gui/animation finishes it fires back to the server with action hash then the server deems whether or not it matches with whats on the player's data store and if it does then it erases that old action hash from the data store and considers the message from the client to be a valid action completion. Now I'm gonna watch this to see if it remote functions are better than my convoluted action encryption

[@ChampionsDontWearShirts-hv6cr]

I disabled my leaderstats script and copied the necessary lines for my remote function button into a new leaderstats script and it worked. Could you or someone explain why this happened and how my other remote event script could have effected it?

[@valerix7613]

@@GimboFlop I'm a new scripter here so apologies if I made a mistake. I think you can use "debounce" (basically just a variable but I saw many ppl use that name) and set the value of it equal to false. Then add an if statement inside of the function connected to the MouseButton1Click event. This is how I do it: local remote = game.ReplicatedStorage.RemoteFunction local debounce1 = false script.Parent.Pizza.MouseButton1Down:Connect(function() if not debounce1 then debounce1 = true local success = remote:InvokeServer("pizza") if success == "Pizza Purchased" then script.Parent.Pizza.BackgroundColor3 = Color3.new(0.137255, 1, 0.207843) script.Parent.Pizza.Text = "Purchase Succeed!" else script.Parent.Pizza.BackgroundColor3 = Color3.new(1, 0, 0.0156863) script.Parent.Pizza.Text = "Purchase Failed!" end end end) Btw the code is different from the video in some places but for me it works. Let me know how it works and hope this could help!

@@GimboFlop You can just set a if condition that checks if a tool already exists in the backpack and then once it does, disable the buy button and put like "Bought" or "Failed" in the text.

Anyways I had headaches until the morning but I still did it. I made the shop a toggle-able popup when you pressed a "Shop" button in the left corner. Also I used a table with prices n stuff cuz I still didn't fully understand tables. Now I understand tables too. I didn't make a prompt and instead just made the button itself say the purchase was successfull.
