The ultimate guide | How to Save & Load your unreal engine 5 game | ue5

[@cmulder007]

I have been a professional developer for 35 years now (although unreal dev is a hobby). I have watched a LOT of unreal tutorials and out of all of them, you display the best understanding of best practices, patterns, segregation of concerns, SOLID principles and decoupled code!! It is very refreshing to see in contrast to many tutorials teaching very bad habits!! Well done and thanks for the videos!!!

Thank you so much for your kind words! I'm glad to hear that my videos resonate with your experience and understanding. I appreciate your feedback and support 🙏

I am mostly commenting for the algorithm, but your content is of the highest quality for the unreal engine i have come across. Keep up the amazing high-quality content! I love how descriptive you are on the reasons to do each step and its less like a tutorial to get the system into the game and more a tutorial on how to use the tools of Unreal Engine in a logical fashion. Thank you!

@@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.

I have been working with Unreal for over 2 years and have seen hundreds of tutorial videos from nearly a hundred creators. This is by far the best tutorial presentation on an Unreal topic I've seen. I don't like comparing people, but if I had to, I'd say that "at last, we've found the Brackeys for Unreal." Well done, sir!

The only thing is when you said naming, you meant the naming when promoting to a variable in the side panel for default right? Great Tutorial from Ali the only part that trips me up is when they use the bad way to do something but keeps items from it as I watch the repeat and try to skip the bad practices. I completely missed the Slot1 default naming and once I slept redid the whole thing I got to that part and fixed my code.

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]

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

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.

Hey there, thank you for your kind comment! Creating new save slots for each game start and handling the information update in the load game widget can be a bit tricky at first.

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

[@AliElZoheiry]

Hey Hades, thank you for your comment. I'm really glad you found this useful, and I appreciate that you see the value I provide. And thank you for the video suggestions. The inventory system is indeed an interesting one. I suggest tutorials by "Ryan laley" he has an entire series on making an inventory system

[@sutadoralive]

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!

[@AliElZoheiry]

Hey there! Your English is great, no need to apologize. Thank you so much for your kind words and suggestions.

[@kellowattentertainment]

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.

[@AliElZoheiry]

[@TheJMBon]

Instead of saving Actors by class, I found that saving Actors by Tag is much better. This lets me save any Actor that has a specific tag, regardless of the Actor class itself. Using this, I can make one FOR loop that saves cubes, NPCs, Niagara Effects, etc. ... basically any Blueprint Actor with the tag.

[@AliElZoheiry]

Thank you for sharing your approach! Using tags for saving actors is definitely a flexible method. It allows for more dynamic saving and makes it easier to manage different types of actors in your game. Great tip! 🙏

[@aviatorkeyz899]

How would I alter this code to enable save by tags for my actors? I believe that would be a better way to handle saving

[@Vindettacon]

Really great resource as usual but a few small notes that may improve further for those interested in the interface definition. At least for this game as it was laid out we don't need LoadGame or SaveGame on the BPI interface since they aren't used externally (which was the focus being that we are using the interface to avoid a cast). It is actually better (given this implementation) to have them be private since they require other bits of data to be set up. Save and Load look like they are purely logic for writing the SaveGame to a slot and should only be used via public methods like SavePlayer or SaveCubes since they ensure that the SaveGame's member variables are actually set up appropriately. That being said I completely understand why you initially treated them as public to make your point and support the flow of the video. To summarize the BPI_SaveGame could shrink down to just supporting GetGameData, SavePlayer, and SaveCubes. the BP_GameInstance would then still retain the save and load methods but privately.

[@AliElZoheiry]

Hey! Thank you for your insightful feedback and suggestions. I appreciate you taking the time to share your thoughts 🙏

[@BlueSpawn]

Great tutorial. Quick suggestion. Casting is not ideal due to memory impact (though you could argue it could be small in this case). What I did was add a function to the BPI called "GetSaveGameBP" then add the interface to the BP_SaveGame and for that method, reference "Self" then return it for that method. In the GameInstance BP, I call the Save Game that's outputed from the "LoadGameFromSlot" methods, call the interface, return the BP_SaveGame and set it to the BP_SaveGame variable there.

[@AliElZoheiry]

Thank you for the suggestion! I want to clarify that Casting has zero impact on memory when the actor being cast to is already loaded in memory, such is the case for all framework classes, they are always in memory already, so casting to them makes zero difference Many people believe that casting is bad for performance, but this misconception often stems from misunderstandings about how casting affects memory usage. Casting is only problematic if it creates hard references between classes that shouldn't always be loaded together, which leads to increased memory usage.

[@BlueSpawn]

@@AliElZoheiry Great point.

[@meathelix]

This is an excellent video running through all of the steps needed. I'm worried about scalability though. I don't know if there's a better out-of-the-box approach, but having to make new structs and arrays of variables for every new type of actor that I introduce to the game, not to mention things like components that might have health states or inventory in them, it seems really daunting to support as a project grows. I would love a way for BPs and components to handle save state within themselves and talk through the GI to the savegame actor somehow, without me having to add special case variables to the save game when things are added.

[@AliElZoheiry]

Hey! Thank you for your thoughtful comment. Scalability can definitely be a challenge as projects grow. One approach could be to use a more generic struct that encompasses shared properties for various actor types, reducing the need for separate structs and arrays. You can also consider implementing interfaces for handling save states, allowing components to manage their own data while still communicating with the Game Instance. This way, you can keep it flexible as you introduce new elements. Just a thought! 🙏

Keep it up. You make the most useful videos on unreal and game dev. I really appreciate it as it demistify the game engine. 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.

[@AliElZoheiry]

Hey there! Thank you for the kind words and suggestions! I'm very happy to hear that you find my Unreal and game dev content helpful. Level up systems and inventory management sound like fantastic topics to cover in the future. Turn-based games like XCOM are also an interesting idea, but a bit out of my comfort zone! I appreciate your support and encouragement. Stay tuned for more content, and I wish you the very best with your game development journey too. God bless!

You should do a missions tutorial. I just finished mine after scrolling through videos on videos of tutorial that were lazy, not practical and just unorganized. I actually referenced your video on dependencies to set up my objective system. At some point I’d like to improve it with a data table and a few more structures if needed but for now what I have works but there’s just so many improper over simplified tutorials on objectives

Hey! Thx for all your amazing content! I have an amateur question if someone can help. I did the tutorial so when i exit the game and enter, it load perfectly at the checkpoints. The problem is that i dont know how to make the "load" when and where i want. I wanted to bind a key so when i press it it load the last save. I set the input key in my character BP but dont know what to do now ;(. Any help?

[@doudar41]

@@AliElZoheiry I have one more question. I've made save/load system using your tutorial but instead of making separate file for each save, I've made struct (SaveFileStruct) and dictionary of them in one save file. It works and I feel like it's better manageble system but maybe I don't understand downside of this approach. Are there some downsides?

[@AliElZoheiry]

A single file is fine if you always want to load the data together and the data isn't that big, but if you have a hundred levels in your game and save information about every single level, then it doesn't make sense to load 99 levels of useless data everytime​@@doudar41

Dude, I hope you’ve quit your job because I’m eagerly waiting for more videos like this. As always, it’s amazing! What sets your tutorials apart from others is that they’re not just purpose-oriented but also follow proper programming principles. Thank you so much, my favorite KZbinr!🥰🥰

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.

[@AliElZoheiry]

Indeed, I realized that as well from some of the questions. I hope to clarify these things in future beginner level tutorials

Amazing and brilliant tutorial. one small bug I found is that if I exit and play again on the same checkpoint twice my health would go back to 100%, I am using your damage system btw Edit: Same thing happened to you at 31:52 and 32:59 without you noticing. you are the best UE youtuber out there and thank you for all your tutorials

[@AliElZoheiry]

Hey! Thank you for your feedback and for catching that bug. This indeed happens because as soon as you spawn on checkpoint, it triggers the SavePlayer function, which could occur before the health has been loaded. To solve this, you should simply ignore the checkpoint on spawning (either through a timer, or checking the location)

[@DylanPlayzz871]

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.

[@AliElZoheiry]

Hey there! Thank you so much for your suggestion, I appreciate your support and feedback. I'll definitely consider creating a video on a weapon system and ammo system in the future. Keep an eye out for more content!

You should resize the array one time for the cubes and then set the indices. Calling add creates a new array every time. Big cost if you end up with a lot of objects.

[@NepahelmShadow]

Absolutely awesome content man, really appreciate this stuff. Keep it coming. You made the thought process and the process itself so simple to understand. I used to get overwhelmed by the amount of code I was working with, trying putting everything into one event graph.

You’re a legend for making this video. I just a have a question, how can I save progress to my game, for example if the player reaches a specific place, he can’t go to the previous checkpoint but only to the next one

[@AliElZoheiry]

Hey! Thank you for the kind words 🙏 To save progress and restrict the player from going back to previous checkpoints, you will need to store information with each checkpoint that tells you its order (e.g which one comes before the other), and then when you reach a checkpoint, before saving, first get your last saved checkpoint, and if it is "after" the one you are currently on (based on the order information that I mentioned above) then don't save, otherwise, proceed normally and save

[@HunterFloris]

Amazing guide Ali! But I have a small issue I'd like to adress and it took me some time to find out. Basically when i load the save it worked first time around.. but after closing and opening the editor a few times I noticed that it didnt properly save.. like my values got reset again. Different weapon, health, etc. Turns out when you open up the editor again you already in the overlap triggerbox, meaning it tries to LOAD and SAVE simultaniously... and i dont think Unreal Engine really likes that. And therefore can give issues. I fixed this by adding a new variable to the checkpoint, a checkpointID. I then cast this value to the Player as variable 'CurrentCheckpointID' and I use this in the GetPlayerSave and struct too..Then on UsePlayerSave I set the CurrentCheckpoitntID again from the info of the struct. Finally on checkpoint I build a branch check.. if the currentcheckpointID of the player is equal to the checkpointID then prohibit the save feature. This means when you load in and retrieve the save data it wont try to save over the load functionality. Hope this helps someone out!

[@AliElZoheiry]

Hey! Thanks for sharing your findings, that’s a really helpful solution! It’s great that you figured out a way to avoid the simultaneous load and save issues. I indeed heard about this issue from a few others as well. Another quick way to resolve it is to not save on first load, by disabling saving until the "End Overlap" event of the checkpoint is triggered, but your way is also quite an elegant solution 💪

i Love these videos man you do such a good job explaining and getting a good idea of how to move forwards too me like 20 min but i passed references for weapon and ammo in to the save system so now i can save my game but im following with all your videos and ive built the ai from your stuff and im wondering how i would go about saveing their data into ive been at it for a min but im not sure what to do. anyway you could point me in the right direction for where i need to start with this

[@halfrican8682]

i Have found the way to pass the reference for the class and get them to save transform and health im a little confused on how to manage the individual enemy though currently they just spawn on top of easch other

[@AliElZoheiry]

Hey, I really appreciate your kind words! 🙏 It's great to hear that you're making progress with the save system and AI. Generally speaking, to save any type of data, try to identify unique things about what you want to save. So if you want to save individual information amount different enemies, then you can add unique names or tags to them to be able to differentiate them from each other, basically giving each of them a unique identifier that doesn't change once they are spawned

[@halfrican8682]

@AliElZoheiry ok kool I'll look into that and try this. The way I was going about it was making then all spawn back in from the first ai on the list. I never thought about unique names thank you for your reply

This is a great tutorial, very detailed and simply explained. Do you think is worth it making the save systen in c++?? Thank you!

[@migame25]

[@cmduilio]

@migame25 why though?

[@AliElZoheiry]

Thank you for your kind words! 😊 As for the save system in C++. There isn't much benefit in making it in C++ over blueprints, as a save system is usually quite light weight. But... if you are doing a lot of complex calls in your save system and you are noticing performance impacts, then moving it to C++ is a potential upside, but it all depends on what your profiler says

[@cmduilio]

@@AliElZoheiry thank you, that was what I was doing, it started to get tricky having multiple NPCs and states more than transform that I have to keep track. Or state of doors, bridges or every actor, but I guess that's how it is. Thanks!
