Roblox data persistence

This tutorial will show you how to create a basic data storesave sample data, and read the data back into a game session.

Data persistence usually refers in programming to data structures that preserve the previous version of themselves when modified. On ROBLOX, data persistence instead refers to a mechanism put in place that allows games to save data about a player in a database and to load that data later from another game server for the same game. The current data persistence mechanism, which there are plans to extend, can only save data that is said to be per-game per-player, in the sense that saved data about a player can only be loaded from the game from which it comes in a game server where the player is present. Data persistence is usually used to preserve a part of the user experience from one game server to another: if a player leaves a paintball game and later joins it again in another server, data persistence could be used to preserve statistics such as the number of times he has won versus the number of times he has lost. There are various usages of data persistence, but most are related to preserving user experience. It is not currently possible to save data about the game itself that can be loaded at any moment.

Are there any games that use DP and have a player base? I never used Data Persistence, but about a week ago I was curious to learn about it. I experimented with player:SaveInstance and was so surprised to actually see it could save entire models. I have a slight suspicion that someone at Roblox saw me using it last week and made the decision to remove it. It would be nice if instead of completely deprecating these functions, it would automatically make a DataStore call instead, because I actually do have an old game that uses lots of data persistence calls. For one, it is inefficient, as it is unlikely that you will need all of the properties to be saved. Also, Roblox said that in the backend, it would be impossible and not something they would be interested in doing, as long as they use JSON storage which I doubt is being changed. However, if this is really neccisary, you can use something like InstanceDataStore. I already did a source code check and is optimized to not save properties that are default to save storage space, making the 4 million byte limit not too much of a worry. This would however mean that data would not save cross play-session, but it will at least stop games from completely breaking and stop functioning.

For information on the amount of data that can be stored, see here. B end. Sign in to edit.

The stamper just inserted models and SavePlace published changes. However, to save an instance now, you are required to use a script that converts an instance to a different format that can saved in DataStores such as a table. RIP to everything that people made in the stamper tool building places. Funny how almost nobody here knows what DP is lol. The first and last time I used Data Persistance was in when I was a begginer scripter! Later I learned that you could nest tables and make your own instance saves… I wonder if everyone at Roblox just forgot that this once existed for years and noticed now lol. Check out Datastore2 , I never had a single data loss since I started using it.

Hello, developers! Everyone seems to dislike datastore service because of dataloss, ratelimits, and the savings abilities it has. However, I am here to show you how to program a datastore correctly, fixing these limitations. If you are new to datastores, no worries. The first few details are about how to create and use a datastore. Even if you aren't new, I would take a peek at it, as I try to explain the process. S, make sure you have this button checked. To get started, you need to first create your datastore. Start off by calling the Datastore-service. If you rename it, be careful.

Hey why is this text blue…? I doubt any games other than old ones still use Data Persistence. Save your player data with ProfileService! But wait! Unfortunately, you cannot save or load data from a localscript; you must use regular scripts. There are various usages of data persistence, but most are related to preserving user experience. In its most basic form, pcall accepts a function and returns two values:. Requests on a data store key are placed in a queue and, if the queue fills up, additional requests will be dropped. Server crash maybe, but server crashes are very rare occurrences, and even then you can mitigate this by auto-saving. I have ported it over to datastores however, so no worries there. Also, Roblox said that in the backend, it would be impossible and not something they would be interested in doing, as long as they use JSON storage which I doubt is being changed. For example, SaveBoolean 'Happy? Simply, Data Persistence stores all user data in one file. If you think about it though, if your game only consists of one place, could you not achieve something like this or use Data Persistence members to support the Data Stores?

In addition to persistently saving data such as player profiles in DataStore, we understand that there are many use cases that need more frequent, ephemeral data access. For example, you may want to build a global marketplace with shared inventories across all servers where the data needs to be updated frequently. Moreover, you may want to have a skill-based matchmaking system so that players can enjoy more engaging competitions.

This will access the PlayerGold data store if it already exists, or create it otherwise. Leaderstats not saving. Hi developers, Data Persistence DP is the legacy data storage service offered by Roblox to save player data and has been deprecated since Finally, we have our script! However, the different system design and data schema makes it super difficult to do. Namespaces Book Discussion. Does any new game even use the legacy Data Persistance system? To answer the question: Albeit deprecated, what is your take on using Data Persistence in new works? Data persistence. Now that you understand basic data store usage, test it out in a sample game.
