These classes are fantastic. 1st channel I've been able to stick with more than a few episodes without getting lost. The way you repeat explanations from previous lessons each time you use a method is extremely helpful. Thank you so much for making these lessons :D
@@livinfreestyle6727 I did have a question but I removed it. You basically answered it later in the video and I managed to resolve the problem I was having from there. Still loving the classes btw thanks so much :D
Enjoying this series! I feel like at some point here you should spend some time to talk about the different classes of blueprints (pawns, actors, etc) and how two different blueprints can reference each other, because currently this is very much a black box.
I've watched so far and there's a lot of easily digestible info, these are some thoughts I'm having so I figured I'd share! Classes and inheritance and so on seems like a natural progression after loops so I think that's good to have next, which I'll also watch, but I personally think it would be even nicer if everything you've taught up to this point came together in a natural way, not grocery lists and print strings and hypotheticals but like a small project. Especially since the target audience I think are people with no or little experience in either programming or blueprint and from my experience what usually holds them back is that they might understand the concepts well but actually putting it in practice with something they came up with on their own is either too daunting or too ambitious for a first real project. Then again, I don't think this way of teaching is wrong or anything but using what you learned in a real project is naturally a lot of fun, and these basics will also "click" faster when you actually put something together that can be played and have moments of "Oh! So that's where you can use this!" Maybe something simple like a Pacman project or something where you go over and use all the topics you've covered in this series. All you need is some walls out of cubes, some collectible coins out of cylinders, a couple of enemies out of squares that try to eat you, a player character out of a sphere or something and the content is simple enough to explain and to follow along with I'd say. And then there's also nice places to go over things like arrays to hold collectibles and enemies, vector math for very simple enemy detection so they try to eat you, timing stuff for things like power up spawns, variables to hold stuff like score and lives remaining the coordinates and direction and what not, loops to build the maze level and well, some basic collision on overlap and you basically have a game out of every topic you've covered so far minus the collision but that's also still pretty easy. Just an idea though, anyway, keep up the videos, I just stumbled on you so I figured I'd check out your content, there's a lot to binge but I'm looking forward to beyond the basics! 🙂
I think this is a great idea. And past me must have totally agreed and that’s why I started making mini games. Have you checked out the twin tickx shooter or the horde mode?? I have a couple more minigame videos coming, but there’s just so many videos to make overall. Thanks for watching and taking time to share your thoughts. Welcome to the channel!
@@livinfreestyle6727 Hah! I had no idea, I figured blueprint fundamentals would be a good place to start. I do have a C++ background but am completely new to unreal engine, so I figured I'd start with a playlist on blueprint, then move on to something like ALS or motion matching and go through as much documentation as I can digest. But I'm glad to hear past you agreed and had the same idea, I'll make sure to check it out! 😉
@@Fred1989 After something like fundamentals, unless they have specific learning goals, the mini games are a good way to get the "bigger picture". You also posted a comment about asynchronous stuff at one point (did you remove it?) that I can't find. I was just going to say "thanks for sharing so much info and maybe I can do a vid on it at some point".
You mention that the For Loop is preferable so that you can manipulate the index of the array element, but the For Each loop also has an index that you can use for that same purpose and is generally better when processing the whole list. The Advantage that I see with the For Loop over the For Each Loop is being able to control start and stop points, so if your array is too long to process between frames, you could break it up into 2 or more parts to help reduce lag.
I generally use For Each. I only use the for loop in specific cases where I need to manipulate the index as you have described. I don't remember saying the for loop was better. I think I said it was better or would help solidify our understanding of arrays and the indexes, but it was a while ago so who knows. So for clarity, I use ForEach almost all the time
@@livinfreestyle6727 It was at 23:00 in the video where you said that "this is an example of when you might want to use the index, start and stop...", pointing directly at the For Loop instead of the For Each Loop, even though the For Each Loop has the same built-in index mechanism. Of note, and I had to dig through some documentation to find this, the for/while looping mechanisms in UE are designed to execute entirely between frames, which means that you cannot use a Delay inside these built-in looping mechanisms, and would have to make you own home-brewed loop using conditional branching if you wanted to have it contain a Delay inside the Loop itself.
@@gregnelson4068 Yeah that's fair. I wonder if in the old days it didn't have the index and so I kind of overlook it. Good call out. As far as delays etc in loops, yeah anything with time can be fun. I have found more and more that my own rule is if I'm using a delay then it's worth rethinking cuz maybe there's a better way to achieve it (because of multiple times where the delays don't work within a tick etc etc)
As always, a very helpful tutorial that imparts important knowledge. It would have been cool if you had explained the modulo operator. I spoke about it with chat gpt for quite a long time and I understand the concept, but it still confuses me when I think about it.😅 Thanks for the tutorials!😊
Another great video. Man all the tools are just crazy. I hope that one day I can really call these types of tools to memory. Just so much to remember. lol
This is awesome! I'm currently making a game kind of similar to Crusader Kings. It got to the point where I have so many cascading branches that I'm just like "There's got to be a better way of doing this..." The problem I have is that I always knew roughly what a For/ For Each loop did, I just can't wrap my head around all the different scenarios in which they can be used for. So, for example, in my game there are a bunch of different settlements... each settlement has their own farms, sawmills etc. and each of those buildings are different levels... So I'm trying to visualise how I can get each building for whatever current settlement you have selected and then do upgrades, resource production etc. I'm thinking I may have to go back and create some arrays for the buildings in each settlement. I did design it on paper first, and I have a GDD for it... it's just one of those things where it all looks good on paper until you start building it and then you realise something isn't right 😅
Thanks, Kevin! I had the best day following this series. I am not new to scripting, but you've filled a lot of gaps in my knowledge by patiently trough all these steps, especially in Unreal Engine. Thanks for being part of my Unreal Journey!
Glad it was helpful! Working on more vids and a guide to know what's where. Also don't forget to check the "Live" section for more general tutorials. Thanks for watching and dropping feedback
There is so much in this series that I need! I hope you get into the best way to store or organize data too, idk if that is arrays or data structures or databases (are there more ways?) For context, I am thinking specifically about game creation like, RPG with lots of creatures, furniture, and inventory management. I found this playlist while I was trying to research what is and how to use a database - with the suspicion that that's what I will need. Thanks again
Database is on the list, but it sort of got deprioritized cuz there is so much to do before that. But we'll get to it. Glad you are finding value in the series
can u please explain like this input movement function , from scratch what the equation !! input axis ! direction ! speed . please make input movement , camera controller built in function from scratch to understand what happen!
It sounds like something we cover in the twin stick shooter. Check it out. Create Your Own "Twin Stick Shooter" Mini Game | Unreal Engine Beginner Tutorial ua-cam.com/video/Wg7BGVOOk5c/v-deo.html
I have a question that i was wondering about for a long time. If i have a Struct and give a Float a Value and name the variable its self explainatory what happens in runtime. If i make a Float or String ARRAY its also self explainatory because i can get the index at runtime. But what happens when i have a struct and use a Enum Array for a variable? Does the Struct store two Enum REFERENCES, so can't i access whats inside of that or are there two references to those enums and i can also access the contents (default variables of those enums) ? So as a practical example : Enum Weapons - Knife, Rifle, Launcher Enum Ammo - None, Bullet, Rocket Struct - Guns Weapon Types & Ammo - Enum Array - Enum Weapons, Enum Ammo If i make a struct and feed in both enums, but when i call to get the values INSIDE those enums at runtime will it return the Enum Adress itself or also the variables inside that enum?
The example is sort of confusing...let me see if this is your question. if you have ENUM_WeaponType and ENUM_AmmoType and you make a struct STRUCT_Weapons Name -> String Type -> ENUM_WeaponType AmmoType -> ENUM_AmmoType you then have an array of weapons of your struct you will have Pistol, Gun, Bullet Rifle, Gun, Bullet RPG, Launcher, Rocket if you then get the Weapons[0] you will get back a struct that has all the info....Pistol, Gun, Bullet
getMaterials, returns and array. The foreach over the array and set material (using the index) to whatever you want it to be). I think I cover it in this vid: ua-cam.com/users/liveiPlgo_pVqys?feature=share
I'm a fan of learning in context. So any "mini" experience/game you can find that is in the genre or direction of the things you want to create would be great. So if you wanna make a platformer, basic platformer tutorials for example.
This was my previous PC (the one at the time of the recording): Intel XEON E3-1230 v5 Quad-Core 3.4GHz (3.8GHz TurboBoost) NVIDIA GeForce GTX 1080 Founders Edition 64GB ECC UDIMM DDR4 2133MHz (4 X 16GB) It could not handle streaming at 4k and unreal at the same time so I eventually had to upgrade in order to get you all higher rez.
the only issue i had was to destroy object from an array . like i had a collision and get all objects inside it and wanted to delete them. but it keep throwin errors
I do not know what I broke, but after getting to about the end, now when I go back to the old parts of the BP and connect the event begin play to them, they just run the loop over and over again rather than stopping, even the ones we made where it should only run the number of index -1, still prints the name over and over. It seems like it has to do with the number of times I duplicated the house on in the viewport. That determines how many times it tries to run the loop. Any idea how to fix that? Does it have to do with the fact that each of those things also have the same BP attached to them?
Thank you for your tutorial. I have a question. You accessed to house actor with 'Get Actors of All classes', but if I want to access to the mesh in level but which is not blueprint mesh. If I want to control the mesh(or mateirals that inlcuded in that mesh) in my specific blueprint, is it possible to access to the normal mesh? (I am sorry for my bad English, hope you understand my question)
You mean the skeletal mesh or the static mesh within a blueprint? In that case you would get the blueprint, then get component by class OR if you already have the "type" of BP you can just access it directly
@@livinfreestyle6727 HEY When i make changes like in mod(%) node i put the value 3 after that i see my 2 models get bigger and when i change my value to 4 it still make 2 models bigger instead of 1 (i put 5 models on my map)
Thank you so much! These kind of tutorials is what the industry needs, not just simple "follow my lead" type without explaining the why's and how's! Congratulations!
Hey I'm learning UE after about a year and a half in Unity, am i correct in assuming we'll use C++ for advanced custom behaviour such as character movement etc, and use blueprints for the majority of the simple tasks we have?
In that specific case, maybe. There are already several character movement components that are available in BP and you would only have to go to C++ if you wanted to create a custom one.
Wow this is an amazing channel! it's hard to find thorough tutorials like these I find, yours are high quality. I lack the blueprint fundamentals and I get lost so easily trying to figure it out on my own without scripting experience, I'm relieved I can go through all your videos and learn properly!! Very good class and good pace, thank you so much for taking the time to make these!!
You can try delay nodes, BUT delay nodes in For Loops often don't play nice (it messes with time and your for loop is trying to finish in one tick) so you might need a timer by event instead
I recently tried to use a 'while loop' with a check for if the random item was unique or not. It was in an effort to randomize an ordered array, which I later found could have been done with a shuffle node instead. I would be interested to know what your thoughts are on both the 'do while' (mainly because my setup would error on occasion, calling it an infinite loop detected error) and on the add unique node, since it will output a -1 index if the attempted add was not unique. What sort of use cases are there for these nodes on their resulting behaviors?
I generally use "do while" very sparingly, I actually can't even remember the last time I used one and this is largely because of the infinitely loop potential. Often a do while can either be solved with whatever you are doing in a timer or tick. If I find my next use case for a while loop, I'll post it here. As for add unique, use this all the time. If I am keeping track of characters, items, projectiles etc, I don't generally need more than one reference for example.
@@livinfreestyle6727 Thanks for the fast reply. I appreciate your insights! I still think that my setup was reasonably safe, and it did work for randomizing the array output, but it would enter the infinite loop crash if I tried to apply it to too large a group (this was a card dealing function, where I wanted to pull random cards from a deck of cards). When used on less than 10 it worked consistently, but with more than 10 it would crash frequently, and more than 12 it would crash every time. So strange! Thanks again!
@@SJ98296 Is there any reason you couldn't use a card deck and just get a random int in range to get the value from an array randomly? Just keep track of the index so you don't use the same one twice type thing. Don't know the full extent of the application but that does work for getting random stuff
Thanks again Kevin, great as always. Just wanted to understand one thing. Why did you set array elm when you can use print string? Isn't that the same thing? Thanks
@@livinfreestyle6727 ah of course its from 20:24> also I see you get actors of class because you have a bp mesh...what if I just wanted to get all static meshes in the level? Do I need to use tags? Thanks again!
Got it now. The point of this was to actually update the values that were stored in the array. I could have gotten the item, appended an 'S' and printed the result and that would have printed the same thing, but the whole point was to actually update the stored values in each index
Please keep these videos up, they are excellent. Continue getting more complicated and more in depth with systems.
The hope is through you alls support we can not only keep them up but also keep making more :) Thanks for the watch and dropping feedback!

Glad they are helpful, thank you for taking time to drop a comment and let me know.
What do I do if i want the house to change one by one with a delay in between? And thank you so much for the great series :)
You can try delay nodes, BUT delay nodes in For Loops often don't play nice (it messes with time and your for loop is trying to finish in one tick) so you might need a timer by event instead
❤ You are amazing ❤
Thanks moh and thanks for dropping feedback and the watch!
I recently tried to use a 'while loop' with a check for if the random item was unique or not. It was in an effort to randomize an ordered array, which I later found could have been done with a shuffle node instead. I would be interested to know what your thoughts are on both the 'do while' (mainly because my setup would error on occasion, calling it an infinite loop detected error) and on the add unique node, since it will output a -1 index if the attempted add was not unique. What sort of use cases are there for these nodes on their resulting behaviors?
I generally use "do while" very sparingly, I actually can't even remember the last time I used one and this is largely because of the infinitely loop potential. Often a do while can either be solved with whatever you are doing in a timer or tick. If I find my next use case for a while loop, I'll post it here. As for add unique, use this all the time. If I am keeping track of characters, items, projectiles etc, I don't generally need more than one reference for example.
@@livinfreestyle6727 Thanks for the fast reply. I appreciate your insights! I still think that my setup was reasonably safe, and it did work for randomizing the array output, but it would enter the infinite loop crash if I tried to apply it to too large a group (this was a card dealing function, where I wanted to pull random cards from a deck of cards). When used on less than 10 it worked consistently, but with more than 10 it would crash frequently, and more than 12 it would crash every time. So strange! Thanks again!
@@SJ98296 Is there any reason you couldn't use a card deck and just get a random int in range to get the value from an array randomly? Just keep track of the index so you don't use the same one twice type thing. Don't know the full extent of the application but that does work for getting random stuff
Thanks again Kevin, great as always. Just wanted to understand one thing. Why did you set array elm when you can use print string? Isn't that the same thing? Thanks
Can you help me out with at what time stamp? I'm looking through now but can prob get you a quick response if I know where in the vid
@@livinfreestyle6727 ah of course its from 20:24>
also I see you get actors of class because you have a bp mesh...what if I just wanted to get all static meshes in the level? Do I need to use tags? Thanks again!
Got it now. The point of this was to actually update the values that were stored in the array. I could have gotten the item, appended an 'S' and printed the result and that would have printed the same thing, but the whole point was to actually update the stored values in each index
I believe you can just 'GetAllActorsOfClass' and set your class to StaticMeshActor
@@livinfreestyle6727 ah sorry I mean't a specific static meshes in the level.
Great video!
