The ultimate guide | How to Save & Load your unreal engine 5 game | ue5
Рет қаралды 22,805
Күн бұрынThis video will teach you how to save and load your unreal engine 5 game in the most scalable and flexible way. I aim to teach you good code architecture and how to structure your systems in a way that makes them easily reusable, maintainable and scalable.
By the end you will have a system that contains a reusable save and load system that can be copied into any project, and extendable with custom save functions for a specific project.
The common BPI_SaveGame interface functions for any project are (LoadGameData, SaveGameData, and GetGameData) these can be used as is, then for each different project you can simply implement additional custom functions (Like the SavePlayer and SaveCubes that are specific for this project)

About me:
I've been learning game development for a few years now, I do have a background in software engineering, and I also have a background in education, so being able to combine my love of gaming, software engineering and education is the best way to spend my time.
I am currently working on a few unreal engine games as a hobby, but I am also trying to build a community, thus I am creating KZfaq tutorials to find others who are interested in game development and design.

@@AliElZoheiry please make a tutorial on how to create quick item system. Because there is no such course on youtube or udemy. There are mostly tutorials on how to collect items, how to drop items in the inventory, etc. For example; it would be great to see a system where we can have separate slots where skills and quick-usable items in our inventory can be connected and we can switch between objects in these slots quickly without slowing down the pace of the game. My game I developed has become much better thanks to you. I hope we can meet and work together one day. Sincerely regards

I'm right now coming from having written a "quick and dirty" prototype, and going into rebuilding a proper production codebase. Your channel is so perfect for me right now, these are all the exact things I need to be thinking about.

What people fail to realize is you have to call the function you use when loading your game, meaning if you have a attach weapon to socket you have to call that, the game won't automatically do that just because you save and load that your character has an axe in its hand, if you have an inventory system you have to add all of the saved items back in the inventory as if they where being picked up from the world.

Very good quality content from you. I like how you explain the right way of separation of code/data and functionality. I've seen many videos of people just slapping everything in their player/controller blueprints, which will probably work most of the time however it's very bad practice. I think it's due to the fact that many people who jump into UE don't or yet have a very knowledgeable understanding of software architecture.

Went from learning unity through youtube tutorials and online courses to then trying to learn unreal through youtube and you are the first channel I've came across where I felt like I was actually learning properly and actually getting a grasp on the concepts of game development and not just copying what the person was saying, the way you present and do these videos inspires and motivates me, had problems of loosing motivation countless times I've deleted so many projects that i started and just completely lost the will to keep trying, but i honestly get so motivated and learned so much watching your tutorials, so thank you. Can i suggest doing a inventory system video? sort items, look at their stats, apply armour and switch out weapons etc, as its a common thing in games. Personally i would love a AI companion tutorial (Have a soft spot for good companion mechanics such as in assassins creed 3), have a few AI characters you can recruit either from paying them or doing a mission for them and have them follow you and you can give them items to wear or weapons to use and help in combat, tell them to wait, or to patrol the area etc, but a inventory system i think is something people would love especially being a fundamental mechanic in a lot of games

Had to comment, this level of detailed explanation has been very helpful. Currently, I'm attempting to have the game create a new save slot each time a new game has started and the information of those slots updated in the load game widget. So far it's gone horribly, but I appreciate you showing where the best places to store and retrieve data should live.

Hello ! First of all, I'm verry sorry for my broken English. I'm from Japan. I discovered your channel recently and I think it's great to watch your videos that offer such quality content about UE! Well done and thank you so much for it! I am contacting you because I have started the development of an Horror Escape Game on PC. I'm really not a professional in this area, at all, and I would love to see a tutorial about more complex features and, very importantly, a real save menu. There are many good tutorials in English on the subject, but, I only see videos concerning relatively basic save system which do not take into great consideration the triggers (using do once or destroy actor), the collectible objects which would be picked up in several levels, the passage between several levels, etc. What I would really like to see is a tutorial that deals with and clearly explains, in addition to what we basically see everywhere, more complex save system: - Saves (in different slots) and loading games menu - Check points (with a list of all saved check points in the save menu, with the possibility of reloading them) - Attribute and customize the name off the saves - Interactive elements (saving picked up objects, multiple doors when the state changes from open to closed, etc.) - Spawned and destroyed enemies (so that the trigger or event no longer retriggers after saving / auto-saving) - Inventory - When and how properly use Game Instance and Game Mode (with the differences between sublevels and levels) - The save logic between several levels (not just in a single level) - The save logic in a game with only sublevels - etc... A video like this, with great teaching like yours, would be more than exceptional and unique ! Thanks again for all your videos!

I am building an action RPG as a hobby project to learn to build and iterate on ingame systems and have found a lot of use for your topics. Some suggestions might be level up systems (i.e. adding or improving ingame skills) and inventory management including attributes like weight management and or stashing items. Other genre ideas might be turn based xcom type games. I can't find anything recent for that type related to unreal. Anyway, great job...hope you keep it up. Let us know what else your up to i.e. future topics, games you're working on...God Bless and good luck.

You are really the best, honestly. Thank you for your videos and dedication to helping persons like myself be better at Game Development using Unreal. It's really appreciated. What I would love to see is a mission/quest system. I know that would be awesome. So the quest system can have for example: Collecting Items Quests (This would be collecting a certain amount of items, either you collect the items for yourself, or you collect the items and give them to another character) Killing Enemies quests (This can be killing a certain number of enemies or killing all enemies that are either spawned or placed in a level. The number of enemies spawned can vary by being random. It would be really awesome to see how to store the data of spawned enemies so that it automatically plugs into the amount that should be killed on that specific mission. That way you could choose whether to have a set amount of enemies killed to pass the mission, kill all the enemies, or the mission could start by saying kill 5 enemies, but then others are spawned and the objective can be updated while the mission is still active to kill those that are spawned as well making the game more dynamic and enjoyable.) Interacting with actors or character quests (This can be to go to someone and then a small dialogue can be played etc, pick up a specific item. That sort of thing. Like at the start of the game, there's an objective to pick up a sword and another objective of the same mission to equip the sword... that sort of thing) Going to a certain location quest (Have the player journey to a specific location in a level) Timed missions (This is where you have to complete any of the four main mission types listed above at a given time... normally you'd have to get to a checkpoint before the time runs out or collect certain items within a certain time) Combined missions: where you could fuse different mission types into one. For example, you could have the player kill enemies within a certain location, if an enemy is killed outside that specific location, it doesn't contribute to passing the mission. My apologies for the long comment, I just wanted to explain what I'd like to see.

Thanks Ali, this tutorial is amazing! Thank you for properly explaining every step as opposed to just telling us where to put what blueprint :D I was hoping you could help me with a follow-up question; How would you go about saving and loading a huge amount of different spawned blueprint actors as opposed to only the BP_Cube in this case? So far example BP_Cube, BP_Cylinder, etc. etc. Thanks!
@AliElZoheiry Ай бұрын
Hey SweetChili! Thank you so much for this, I really appreciate you 🙏🙏 Regarding your question: the principle is the same, you want to identify what you want to save about your actors, only the minimum amount of information needed to perfectly recreate their state, that could be as simple as the actors class and their location in the world, then you can make a struct out of the data you want to save about your actors, and then just save an array of that struct type. Then when the game loads, you loop over your array and respawn the actors based on the loaded data

Good save game tutorial for beginners. If you dont like the spaghetti inside of a function just treat your input variables as if they were local variables. The 2 most important parts of this are: 1 use the game instance, even if the game is multiplayer. 2 create base classes for anything you want to save, so that like the end of this video you put save functions in those base classes.

Hey Ali! Amazing tutorial as always! Quick Question; For things to save (Enemies, Items etc..) when you have different levels, would the best practice be to make an array of each level separately? Or is there a better way to do it? For reference; Think of the classic resident evil games, where each room was its own Level. In order to keep track of number of enemies killed, would they have an Array of enemies for every different level or via another method?

Hey there! I'm glad you enjoyed the tutorial! In regard to keeping track of enemies and items in different levels, it's definitely a good practice to organize them based on the levels. You can have your SaveGame data organized as a Map (Map here being a Data type also known as key value pair) where the key is the name of the level and the value is a LevelSave struct, and inside that struct you can have multiple structs as well. That's just one way of doing it of course, it will all highly depend on what you want to save.

I don’t know if your still ready comments in videos from 4 months ago but if you are I would love love love to see a good weapon system video. I been following someone and watching how they do it but they are in consistent Chang things to much and are just breaking the code. To the point where a game I’ve been working on is now just useless and I don’t know what to do. The video concept was having it where the player can hold more than one gun in inventory. One is in hand. And on is in inventory. And you have an option to put both away and just go with hands. Then he changed them all messed it up and then added an ammo system and it just got all confusing. I do want an ammo system but learning the weapon system and ammo system from someone who teaches like you do would be amazing.

Amazing tutorial and a great channel overall, keep it up! I was experimenting with a saving system too and there is one thing that bothers me. You can dress a level with collectible items, however, you can also drop them from the inventory. And there is a bit of a problem - it's hard to manage the Saving System like that. Because some of the items are constructed automatically and then need to be updated if they were collected (aka destroyed) and spawned items that were saved also need to be respawned on load, but they also might have been spawned and collected previously. And it becomes a huge mess and a nightmare to manage. How would you tackle something like that?
@AliElZoheiry 3 ай бұрын
Hey there! Thanks for the support and I'm glad you're finding the tutorials helpful. Managing a saving system with collectible items that can be both automatically constructed and manually dropped can definitely be tricky. One approach would be to maintain a unique identifier for each item and store their states (collected/not collected) in the save data. This way, upon loading, you can respawn the items based on their state in the save data. It's a complex issue, but maintaining a clear data structure and carefully managing the update and respawn logic should help tackle this challenge.
@dzmitryyafimau7647 3 ай бұрын
@@AliElZoheiry Thanks for the response! I'm trying exactly that approach. However, I can't help but notice that it's not very efficient to update all manually placed items on load every time and destroy them if they were collected. I liked your idea not to have the item in level from the get-go but rather spawn everything that you need on beginplay. That way all items could be grouped into the one "spawned" category and that should help manage them more easily. But that would introduce more hassle for the initial setup. Maybe there should be an empty actor-spawner with some parameters to pass to the item on spawn or something like that. Hard to tell from the top of my head without experiments. Thank you anyway, wishing you all the best!

I just have a problem, when I go to the checkpoint it work fine when i reopen the game but when i just quit without doing anything and reopen again, only the location was kept and the rest (camera rotation, player stats were all reset to default) Sorry if i don't explain correctly but checkpoint work, but if I just open the game after going through checkpoint and don't do anything and quit, when reopening, all but character location are reset I retested it and if i just move through the checkpoint again it works, is there a way so I can open the game, and without needing to through the checkpoint again, when i quit and reopen, it'll load the last time I overlap the checkpoint ?

Hey there! Thanks for your kind words and for watching the videos! I am not sure I understand the issue correctly, but the checkpoint should save all this information that is in the PlayerSave struct, and if some of these values aren't loaded when you quit and reopen, I suggest printing the values that are loaded and see if they are correct, this will help you narrow down if the problem is that this information was lost when the game was closed, or was it loaded correctly but not used correctly when opening the game for the first time. Then from there you can find a solution

Hi Ali, I'm using your combat system and implementing the save functionality from this tutorial. I have two questions, first is loading the enemies back on the map. I'm using a for each loop with the transforms that I then spawn actor of the enemy class. When I do this the enemy is in the correct location but just stands there and moving towards me, how get them to move again? Second question in using that same combat system how do I load the current health?
@AliElZoheiry Ай бұрын
Hey there, for spawning enemies dynamically, make sure that in the character class of the enemy you set the "Auto Possess AI" to be "Placed in world or Spawned" otherwise the AI controller doesn't possess the enemy when spawned. Regarding saving the current health, it's the same way, just save the health variable from the BPC_DamageSystem, and on load set it again. Just like I did in this tutorial, but instead of setting a health variable in the character class, you'll see the health variable in the damageSystem component

What happens if you change the data while you are saving ? ( Guess something like that can only happen if you save huge data ) For example weapon is a start save he hasn't saved weapon a yet switch weapon to b save is completed ?
@AliElZoheiry Ай бұрын
2 things can happen: 1. The old data is saving, you change it, that triggers a new save function call and it overrides the old save data, so everything is fine. 2. OR, The old data is saving, you change it, that triggers a new save function call, and the old call finishes AFTER the new one, thus saving old data. That, in software, is called a "race condition" and is an unfortunate side effect of asynchronous functions. So you should prevent 2 saves from happening at the same time just to be safe

I am making a new blank project and had game instance, character class etc. created but I think my problem that I don’t seem to be getting is how to call that character class as you use a call function you made for the weapons, I only have an initialise function for event begin play for my playable character but unfortunately playing with inserting a input and class there didn’t seem to load me anywhere… I am new to Game Development with only 1 team project, definitely want to make this tutorial work although everything up to this point has been checked at least 2 times over so I don’t know why I won’t load when the print string mentions the game has saved 😅 Either way, has been a fun tutorial and very clear so I do like that, just this one part that has me facing a roadblock Thanks regardless, now having knowledge on saving ^_^

Hey there, thank you for sharing your experience. I don't fully understand what the problem is that you're facing. But my advice is the same as I mentioned in the beginning of the video: Make sure to think of what data you need to save to be able to recreate the state of your game, then when the game starts, load that data, and use it when you initalize your player. In my use case, I wanted to store what weapon the player was carrying when they reached a checkpoint, that's why I added the weapons "Class name", then when I start and load the game, I check if there is a saved weapon class, and if so, I spawn and recreate it. Follow the same approach for anything you want to be respawned when the game starts

Hi Ali, thanks as always for this video. I was wondering how implement this system with enemies, so when I kill an enemy and save the game, it never spawn again when I load again. I implement this video in the logic of the tutorial series you made and I insert, at the end of 'event death' node in the BP_enemy_Base, the 'get game instance' and the 'save Enemy' (same as Save Cubes). Then I replicated the 'event save cubes' with a new one for the enemies in the BP_GameInstance, but it didn't works. Am i missing something with this logic?
@AliElZoheiry 21 күн бұрын
Hey there, in order to save which enemies have died, you need to be able to uniquely identify which enemy was killed (by something other than reference, because reference is gone when the game is closed) so by something like name or tag, and then save that the enemy with this name/tag was killed. When you start the game and load the data, if you are trying to spawn an enemy that is marked as dead, then either spawn them and kill them, or don't spawn them
