Plus I love DataStore2, a free tool gifted to the Roblox community by the Roblox community for even easier work with data stores as it caches data to ensure it isn't lost. The only problem in real games is how to decide when and what to load which can become very problematic if done wrong as memory leaks can occur (not cleaning up old data so new data is added over time and causes the server to degrade).
Thanks dude! You helped me overcome the hell of not understanding data stores. Can you also post a video explaining in more detail about data stores, such as what is pcall function and more?
to use pcall, do a variable that stores 2 variables at ones (no, not like this "local thing = {}" but like this "local success, errormessage") and then set those 2 variables to a pcall, and then put a function inside of it. if it errors, it sets success to false and errormessage to the error message. if not, it only sets success to true.
thanks for keeping it simple and sticking to the point, every tutorial I watched was just people giving awful explanations, trying to explain pcalls and other code separate from datastore overloading my brain
God bless your soul dude, i had so much problm saving stuff in my games, now i can do it peacefully instead of punching random words in my keyboard until it does something
Hey nice video, you helped a lot, suggestion: Could you make a video like this with datastores but instead it is where you buy something from a shop and the thing you bought saves in your inventory after you die and/or leave the game.
This was a very informative video and easy to understand. I am creating a game solo from scratch without any experience in coding and building just for fun and I have to say of all the tutorials and information I have found to help me along the way this is by far the best one yet. I appreciate it!
DataStores gave me hell as a newer scripter, but I can handle them pretty well now - my preferred method is to loop through the player’s descendants, saving their stats as IntValues, NumValues etc., and identifying them by their name and parent if necessary. Nice tutorial by the way.
I should add, though, that you should probably add a game:BindToClose(function() along with a wait() and your saving function to act as a catch-all, since Roblox Studio doesn’t always detect when you press the stop button.
thank you sooo much i wanted to learn more about datastores and i tought that if i followed this tutorial i would still make a lot of mistakes and bugs but i actually made it work
I'm trying to make an Incremental game on Roblox, this should help me a lot! I'm new to scripting, I thought of Parent to Child relationship between Instances too literally. I thought the Parent container couldn't be the Parent of the other Parent's children. Now I understand you can search anything if you reference the correct String Value.
I use profile service, because get and setAsync stops working after 200 players in your game in total. Profile Service is just a lot more reliable and it's great for server shut downs.
personally i use profileservice and it works great, finally i managed to master even this lol, even though i guess ima abandon game development, somehow it doesnt fit me, and probably its just fact i always got no game ideas to make, and i work alone ):
@@iamLudius Eh, it's really not that simple. Maybe if you are just using a simple cash system, and that is the only key you need to store. I would say the way you described it is DataStores at their simplest form. They can get much more complex.
@@imthebestmayne122 Ludius explained it in a simple way so that datastores are more approachable. Once you understand the fundamentals of datastores, that means the more "complicated" datastores aren't as complicated as they seem.
@@urnix69 gotta say I disagree with this. No disrespect either to you or the poster. Most of this information (and more) can just be read from the data store api page on the roblox documentation page. What is much harder is finding information about more complicated data stores. Look at somethibt like ProfileService or DataStores2. I guess this video helps understand it at a very rudimentary level, but nothing further than that.
guys heres an advice from me: dont make datastores saving only on leaving! Make it save every time coins change instead, because if its only when you leave, if you can drop coins in your game then you can make a dupe glitch on private servers basically player1 drops 5 coins to player2, player2 leaves and the 5 coins save, but player1 SHUTS DOWN his private server so the data doesnt save, so he has 5 coins again
@@AxajonOFFICIALits so simple, if you have an inventory system or currency just make it save every time it gets changed, like make a new function that runs whenever the value changes and when it does it sets your async and updates.
@@darkarcher908 saving player data everytime a value changes sound like a performance nightmare in any game with fast changing values and a decent amount of players.
They should make it so you could erase everything on game's datastore. Also I have been suffering trying to make a datastore thing, it really depends what you're trying to code.
I need a little bit of help to know if I understand it right. So for me to save data for each player, I would need to make a server script in which I would need to reference every script that is responsible for some kind of system logic in my game. For example, if I have scripts for inventory, currency, leaderboard, et cetera, I would need to first connect those scripts to server script that I will be using for a DataStore and make a table with those scripts inside my server script for DataStore. In simple words, I need to add every script that has to do something with things that need to be saved across sessions and places inside my game to one script that will save those data automatically for me as players join or leave the game..
Very good explanation, but I have 1 question. In this video you made a DataStore for coins, but I have more values to store, lets say for example Stamina, Strength or whatever it is, do I create a DataStore for each data ?
Hey man, I don't know if you'll ever read this, but I have a question about data stores. So like, I got a message from Roblox saying that someone requested for their data to be removed from my game, but I never used this data store thingy, so do you know by any chance if it was any error from Roblox or something?
Should we really use SetAsync for a system like that? Isn't it better to use UpdateAsync? I don't really understand what's the point of UpdateAsync compared to SetAsync
It's all fun and games until you try to datastore a custom item with 7+ values + a lot of other similar items, do you just write the same line of codes a quadrillion times?
As much as I'd like to help you and any other person that may need me, at the moment my schedule's packed, sorry man :[ But maybe I can help you through the dev calls inside the discord server?
ill pay 50 robux who will do working DataStore script (i have 3 values) i checked the 3 tutorials and all of these tutotials doesn't work (ChatGPT also didn't help me)

@@iamLudius How so? Would it be like: You declare a table like "playerData = {}" and then you would use table.insert(table, value) in the player connect function? Then call that table when the player leaves?

is it free
Nope
you can just learn datastore without needing any plugin

I think I am just ass at coding in this, I followed everything and rechecked everything and it still doesn't save....
honestly i just use chatgpt because i have no clue
(but all other scripts are hand written dw)
Tho the script u described wasn’t a really good script because if there’s an error the player won’t get the data at all which is bad

So much wrong with this video. You don't prepare in the event that a read/write fails. DataStores are scary because of the amount of edge cases.
but how do you save multiple values? that's where i get confused cause i have over 100 values
maybe try putting your values in a table and saving the table?
how can i make gui button that adds value to player datastore?
Let's say there is two data. Coins and Levels. How can you save both?
im pretty sure there is a more efficient way to do so then what im saying but just make 2 seperate datastores.
U can do that or just save put them both in a table and just save it to one single player data datastore
