You're very welcome!

yeah, dont try to edit anything about the data asset itself while data aseets can be changed on runtime, you should really treat them as assets, not just blueprints, you wouldn't try to change data about a static mesh for instance either, same goes for data assets. instead metadata like that should go into the itemslot. i'm working on a followup series that'll include some metadata stuff like durability. For something like durability speficailly, i'd probably just put that as a variable on the slot itself. and disable it when it hold an item doesn't have durability. For other kinds of metadata i'm working on setting up a ssytem that uses custom Objects that can hold any amount of data of functions you want :)

​@@thegamedevcave I'm looking forward to your video about it. For now I'm trying an approach using a blueprint of type object, which also has the usual inheritance set up (item -> equipment -> weapon). The object has an attribute for the data asset and the equipment has an attribute for durability and the inventory struct has the object instead of the data asset. Feels a bit clunky too though, and I'm not sure if I'll get issues with that approach later. Like I already noticed, but both my approach and probably yours too has an issue with metadata for each item of the stack, as it saves metadata for the full stack and not one item. If you have something like a health potion with multiple uses but also stackable, I'm not sure how it would work with either approach .. besides making them non stackable to begin with, or move the one that does not have all uses left to a new slot and make it unstackable :/

@@Lilium___ i can't think of many games where items with metadata are stackable in an inventory system honestly. Probably for this exact reason. an item slot usually is just a reference to an item with a number telling you how many of that item there are. if each item needs to actually be it's own individual thing, each slot needs to turn into an array instead. But i also dont think you'll want to do that because if each item in a stack is unique, how does a user interact with a specific item in that stack? If items have different behaviour, it's probably better for the user too if they don't stack so they can acces "potion that heals 50 health" speratly from " potion that heals 100 health" . combing those within 1 stack will probably lead to game design issues rather than programming issues. which is why i dont think you see this type of unique item stacking that much in games.

@@thegamedevcave Yeah I think that's what it comes down to in the end. I've seen some games that let you stack weapons with full durability, but then again you can only equip one weapon (and not a stack), so the metadata of the stack will never be updated, only one item at a time, when its equipped. Having an array of metadata, one for each item of the stack can solve that, but as you mentioned that can be very clunky for the user. Technically if you have a cake that can be eaten 6 times, you can make it stackable and just subtract one after every 6th use. But good luck implementing that without making the whole system clunky. Thanks for the input, I'll stay with non-stackable items with metadata, otherwise it will just get too complex for almost no gain.

you're 100% right. i kind of did a shit job explaining what i needed here. what i was looking for wasn't just a waiting node from blackboard time (because yeah, that already exists thankfully) but more or less an async wait node. Something that counts up in the background while the rest of the tree is allowed to keep running and then after X amount of time flips a bool (or in this case actually an enum value) so the tree starts to run the other branches, until the timer rolls over again, at which point it'll switch back :)

I like the music. What's wrong with it?

​​@@svendkorsgaard9599 its a bit too common and overused. For allot of people it may seem lazy and that kinda ruins the vibe of the video. But do whatever you want if you happy with the results.😁

Glad it helped

as you can see in the video itself, higher poly count will make the displacement smoother. yeah it is because of hard edges, but adding more geometry, even if just flat faces (while not great to do, definitely don't' subdivide it like 10x of course), does help solve the issue. I'd recommend you try it yourself, try importing a simple low poly cube, add the material and then add simple subdivisions to it and see the difference. I'm pretty sure it's to do with the vertex normal. when the cube's faces onto have 2 tringles each, the vertex normals point straight up, perpendicular to the face, but when there are more tringles on a flat face like that, the vertices on the edges have their normal pointing out diagonally, meaning that the offset is done diagonally which prevents the taring issue. you of course don't HAVE to make specific components to display outlines but if you're going to have a LOT of meshes in your game that all need outlines anyway, you really dont want to give every single one of them their own overlay material, that's just tedious, much easier to just make a component for it once and have it all done automatically.

@@thegamedevcave Subdividing usually also smooths edges in addition to just adding divisions. The smooth edges are the thing that fixes the issue, not the polycount. For the character I was talking about adding the outline to the skeletal mesh in the content browser, so that anywhere you use it, it would have the outlines by default. To me that's super comfortable

that's the thing though, in the example i give in this video i specifically use linear subdivision, so the actual edges stay sharp... for the character, yeah that is true, but still that's for every character in your game, if you have like 100+ characters in total, setting up the component like this (even more so when it comes to the static meshes), will save a bit of tedious busywork. Of course, in no way required to do it that way, and if you're just adding it to 1 character there's no need to bother with it, but otherwise, why make things more time consuming on yourself?

​@@thegamedevcave I'm not talking about the shape of the model, I'm talking about the edge type. You can experiment with this in a modeling software like Maya. It lets you select edges and determine whether they're soft or sharp. When importing a model, UE interprets hard edges as being disconnected from one another. It's interesting, look into it! For assigning a material on multiple assets you can select them in your content browser, right click > Asset actions > Edit selection in property matrix.

does this work in ue 5.4.2

there are only so many ways to do it, this is the most straightforward way, i dont doubt there are dozens of people that made videos showing this method.. i recorded this video like a month ago anyway, so just nice timing that we both uploaded this around the same time i guess?

@@thegamedevcave This is simple but performance cost and also two extra draw call one for overly material and the other one for internal mesh I used the @codelikeme channel video which is in post process

yeah it uses up a lot of extra drawcalls, so it's not exactly ideal in that regard. depends on a lot of factors but this is the same basic technique that has been used since the PS2 era for a lot of games. so altogether, it's not THAT big a deal i'd say. Post processing is generally probably cheaper to do though, but is not as consistent in the thickness out the lines.

@@thegamedevcave Just because it's one more draw call, doesn't mean the method is inferior to postprocess ones, entirely depends on the project and frame budgets, there's no 'one correct way' of doing something usually. I personally really like this method (since this is exactly the visuals one of my projects were looking for), so thank you for the well-made tutorial, don't doubt the majority of viewers are appreciative of all the diverse solutions provided.

to be fair it's not just one one draw call, it's one more draw call PER mesh, which can add up quickly so it is something to be mindful of, but overall it does end up looking better than post processing in my opinion and while those extra draw calls might end up adding up to form some performance impact, usually saving draw calls in other ways when possible is probably worth it do be able to use this method :) There's up and down sides to each method for any desired results, this one is the same, just gotta be aware of those and see if they fit the usecase! I'm glad you found it helpful for yours!

All this chat gpt stuff has warped the meaning of "ai" a lot... 😅

For sure that would make for a smoother workflow. Didnt really work very well in this patricular case though. But in general, yeah

yeah that's probably a much better way to combine whole texture sets!

@@thegamedevcave It's a game changer, specially when working with landscape materials

yup, 100% the same, it's just an interface the same as in any other language you're used to. it's all c++ under the hood (kind of) at the end of the day after all

that's a good headsup to have! makes sense, thanks for sharing!

about 99% of progress bars you see in games are actually straight up fake, just showing an estimation of how long the dev thinks you'll take to load a certain scene. (which is also the reason that a lot of games will often hang at 99% loading, because the computer is slower than what the devs expected). there is a function called "GetAsyncLoadPercentage" in c++ which you could use to display true loading times (more or less) but it's a slow operation which will make the loading take even longer, but if you do it on something like a 0.2 second timer or something, you might be fine to use it. As far as i know, with just blueprint you wont be able to do this, and that is most likely because rarely would you actually make a proper accurate loading bar. as with so many things in game dev, games often straight up lie to people to make them feel better.

​@@thegamedevcave I didn't expect you to give such a detailed explanation, but yeah, so far I've never found an explanation on how to display the level loading time in percentage form, most suggest adding a delay, say 2 seconds, but I think this is unfair, if the user is using a high end PC this is a very long time, but if they are using a mid or even low end PC, 2 seconds is a very, very short time, they will even arrive when all the levels have not finished loading, I find this very often especially in indie games, the level is already open but is still in the loading stage, such as textures, lights, even static mesh, thank you for taking the time to explain this in detail😊

Glad you think so!

Glad it was helpful!

interesting question. i'd probably do something like adding an extra attribtue to your attribute set for n. that way, every time you apply damage you can increase n. then when you remove the effect, run another effect that simply sets n back to 0 (or 1, depending n how you code things)

sounds like it's doing line traces at all times, isntead of just when fallign down, make sure you have a branch to check if the Z velocity is less than 0

@@thegamedevcave It only does line traced when falling. But since the character is stuttering up and down after trying to do it. It has a negative velocity for a few frames causing it to re line trace.

sadly, splines aren't means to dynamically change at runtime so you can't animate the spline points

@@thegamedevcave thank you, what about meshes inside blueprint? in your example it will be moving railroad itself, but not "train"

@@alexrybin3798 you might be able to animate some kind of offset varialbe for the meshes, i've never tried if spline meshes can be animated like that. I would assume that also is a problem though since i expect the reason splines can't be animated is that the engine really wants to bake your splinesmesh down to a static mesh. But i've never tested that, so it might work?

oh for sure! dont just randomly cast to a bunch of stuff without knowing that it also loads in a bunch of assets. and even though i'm advacating for using a cast every now and then, i still think setting up an interface call makes more since 9/10. people are just unreasonably affraid of casting and don't actually make any consideration for it as a result.as you say, for most people, they're working on a scale where even if they do mess things up, it doesn't actually hurt all that much with modern computers having more and more memory .

yeah i figured that out while cleaning up the project to make it ready for patreons XD can't believe it took me that long to figure this out XD I dont tend to do all that much in blueprint usually so that was a nice thing to figure out :) !

Found it. We use Attach Component To Component. For Target pin we use "Weapon". For Parent pin - Our Skeletal Mesh Component And for Socket Name we say "hand_r" Remember to switch the socket name to "hand_l" When you select a sword

probably best use a whole other system altogether to be honest. but you could add a socket to both hands, and check when you switch weapons if it is the bow and move the mesh to that other hand... but if youre still looking into a system to make for weapon switching, you're best off just not using this one for your use.

yeah probably good to avoid that XD

yeah, no.. not an option for the cloak, for the rest of the model though, sure. I used it for the skull and spine and such

Glad you enjoy it!

I’m new to unreal and made a inventory system by following a tutorial that used a vertical box and you had to manually assign it to the equip able slot by doing this it applied the selected item it a set bone / socket. Using the knowledge I learned I made my attack system around that. But the only down side to that for me was not being able to auto assign slots and drag and drop things around the ui. So I decided to follow your guide which so far has worked great and was exactly what I was looking for, my only issue now is I have no clue how to add a equip able slot to this ui. Because I can’t do this I can no longer assign my sword to my custom socket meaning I can no longer use my attack :(. Have you please got any tips on how I can go about solving this issue ? I would also love to see you cover this in a future episode. Regardless of my issue I thank you for this very handy guide ⭐️⭐️⭐️⭐️⭐️

yup, but it'll be a while before i get to that. I uploaded this video so my whole inventory series will be completely up for free once i start the followup series later this year that'll dive into more in depth things like item subclasses, hotbars, item meta data and so on :)

make sure you properly build from visual studio, not just use live coding. Aside from that, what does that error say when you try to build?

@@thegamedevcave No errors except the #includes (cannot open source file "AbilitySystemInterface.h and AbilitySystemCompnet.h) and the fact the ability components are not showing up on the character. I did rebuild. I am using 5.4 but i just restarted with 5.3 to see if that makes a difference

Made no difference if its 5.3 or 5.4

Well I got the includes for the AbilitySystemInterface.h working but now the includes for TestCharacter.generated.h and TestCharacter.h are 'cannot open source file

Disregard, stupid mistake on my end lol

if it's not an ability that's reused anywhere else, simply cast and create a function that returns that information. if the ability is something you'll want to reuse for other characters ( like the enemies), set up an interface with a function that'll return that info.

@@thegamedevcave Gotcha, thanks!
