In this 2023-2024 Guide to Roblox Scripting for Advanced 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!

Good Video. Wish you would have added a version number of DataStore. So that in creating a game and you want to reset your numbers back to a brand new player starting over. You can just change that number. I have seen it before. But don't get the jist of how it works.

so UpdateAsync will automatically retry if success is false and keep retrying until it's true?

haven't watched the full video yet, but according to your timestamps you used setAsync, wouldn't updateAsync be better as it lessens data losses?

what about the gui? like data gui? like if player touch the part and frame will visible and if player leave the game and join again the frame is still visible can you make that?

@CONHOOPER 4 ай бұрын

I think i get it now. Doesnt pcall return one value. True or false. That's success right? Then the second return value which is currentCoins depends on what you return in the function which in the case you did PlayerCoins:GetAsync(player.UserId) Correct me if im wrong.

@YTMGK Ай бұрын

Hi, thanks for the very informative video, I'm struggling a bit to get my head around this as I want to keep my userdata in a dictionary, and then just update the whole dictionary to datastor when the player leaves, or recall the whole dictionary when the player logs on. The first problem I run into is when I try to parent the leaderstats folder to my dictionary, and since this is a necessary first step I can't progress further. Any help would be much appreciated. Please let me know if I should add in my code.

Why do we return get async though? Why not just use get async on its own.

@RobloxStudioLoser 3 ай бұрын

Im not sure if you put a datastore into a object, and if you did, then it wouldnt work, also datastores are inside leaderstats scripts so you would open up your leaderstats script, press the + button and add another script which would be the datastore

@weirdwanderer 3 ай бұрын

43:33 Maybe I understood it wrong, but wouldn't updating the date every minute be bad? What if a player leaves before that minute sets in? Do we double-check it with Players.PlayerRemoving?

@BrawlDevRBLX 3 ай бұрын

A mix of both is generally good for safety measure. The server could shut down abruptly, which wouldn't could towards the PlayerRemoving event and then progress would be lost. If you want to, you can change the wait time from 60 secs to something like 5 or 10 minutes.

Should i declare a data store as "PlayerData" and set it as a huge table with diff types of data such as leaderstats settings inventory etc? Or should i separate the data into different datastores? Also in order to avoid any errors and data loss with pcall do the job? Thank you for the tutorial.

@BrawlDevRBLX 5 ай бұрын

I would usually have a main datastore like "PlayerData" and I would use scopes to categorize the datastore like "Inventory", "Leaderstats", "Settings", "EquippedStats", etc. As for pcall, it guarantees a response if fetching the data fails, but it doesn't prevent it. You must take extra steps to retry the data fetching if it fails. There are examples of this online, but I hope this helps you!

@imthebestmayne122 4 ай бұрын

I wish you gave more information about scopes. In most large projects, it won't be single values being saved, ie cash. The Documentation info about scopes is trash, and it is hard to know how to save large amounts of varying types of data, while being organized and concise. I also feel like leaderstats aren't a good indication of advanced data store usage either, considering as I stated earlier, most projects will not be saving just a few IntValues as data.

isnt using userId better for keys in datastore? if a player changes their username they would lose all of their data, for example

@BrawlDevRBLX 3 ай бұрын

Correct! UserId cannot change for a user so that's better to use as a key.

You can save(PlayerLeaving) on which level the player is at the moment then add load on playeradded. Other script on playerAdeed if the value of current level == 2 they should get teleported there or something.
