blueprint

[odd ember]

again changing structs in BP means you're changing a copy

if you use a function like this you're making the changes in cpp directly

and have full control over what gets changed

[thin panther]

ah so if i make my own function, and make it my own node, i can just change the reference directly

[odd ember]

exactly

[thin panther]

that way there can be no confusion of if data gets changed or not, seeing as it is changing the reference of that struct

got it

[magic parcel]

I am sure you were not. However, time is money and becoming a full stack coder is not my intent here. I have the base request knowledge to do what I am doing. I simply wanted to verify what I was seeing matched with what I knew.

I get your point, I dont agree with it. It would be liken to me expecting every coder to go spend 3 weeks learning animation basics, rigging, weighting, animation layers, before they could create a character via BP.

You wouldnt be wrong in asking that, but its not really ideal either. Nor does it NEED to happen in order for the coder to accomplish the task.

[thin panther]

now its gonna sound like a dumb question but when i add those structs as variables to BPs, they are still instanced right?

[magic parcel]

Anyway, no point in going further. Appreciate your time

[thin panther]

wait ofc they are

theyre structs

thats what theyre made for

ignore me im being dumb

[odd ember]

if it only takes 3 weeks to become proficient in animation systems, sign me up

[magic parcel]

took me 1 week, self taught no videos

[odd ember]

it took years for me to understand programming

[magic parcel]

so, get at it

[odd ember]

the scale is not comparable

[magic parcel]

when you come into the art channel asking some questions about it I can point you to some really good books 🙂

then we can be even

[thin panther]

ooh god i remember my early days of ue4, i used 0 inheritance cause oop scared me lmao

[magic parcel]

then, when I tell you to learn about human anatomy and take a class in that, first!! Your point will be made very clear to both of us

[vagrant flicker]

Hey Folks, I made a simple torch that can Inflame other torches that touch.
The problem comes in one of my edge cases:

If the torch is not lit and touches another non lit torch they both will get inflamed.
Any easy way to separate or keep track of the torch state? The problem comes from that I have only 1 torch BP and when my player pickups the torch I guess we cannot know the exactly state of the torch

https://blueprintue.com/blueprint/s3hhgj39/

[magic parcel]

since you cant animate properly unless you fully understand the human body.

[vagrant flicker]

Sorry for the interruption btw

[odd ember]

you'll be curious to hear that programming isn't even my main field

slash final form

[magic parcel]

interesting, certainly

but thats why I am here as well

tired of trying to find coders to help me accomplish something that I have the aptitude to do myself.

[remote meteor]

you can always use a boolean to keep track of the state

[odd ember]

enums can be used for torch state. but if you just have two sates you can use a bool

[thin panther]

that point doesn't hold water, you can animate a convincing animation without knowing every singhle muscle group, as 3D animation doesnt simulate every single muscle group, however it is impossible to write good code without knowing the fundamentals of programming

sure it isnt necessary to understand the question, but if you are going to learn programming, you should learn programming no?

[magic parcel]

It holds perfect water

[remote meteor]

overlap > if the other actor is a torch, and is on flame, then flame myself up

[vagrant flicker]

I thought my "visible" bool plays that role

[magic parcel]

I could watch this guys tutorial and create the stat system

[odd ember]

do come back when you need help architecting your systems

[magic parcel]

100000% it would work

it wouldnt be created "correctly" but it would work

[remote meteor]

you need to check if the other torch is lighted up or not

[thin panther]

but the point is it wouldnt be good, you dont need to learn anatomy to make good animation, but you do need to learn object orientation to write good object oriented code

[magic parcel]

thats the "fun" part of coding. often you can get away with many things

[odd ember]

your present self can get away with a lot of things at the cost of your future self crying over them

[magic parcel]

thats incorrect. Your animation, without knowledge of human anatomy, would never be close enough to "good"

[vagrant flicker]

Yes, but how can I separate them? They are one actor basically copied around the map. My players held the torch but thats all

I am experiencing troubles to determine wheter my player PICKED torch is lit

or not

[magic parcel]

that is not adding in motion rigs 😛

those are cheating!!

[remote meteor]

each torch you are seeing is an instance of them

you can always just get the visible variable from the other torch here

[thin panther]

with knowing the tools good enough and a good reference pose, sure you could make a good animation without knowing anatomy

[odd ember]

no that would go against their point, so it can't be true

[thin panther]

ah gotcha

[magic parcel]

lol... its not even close to true

what will you use to reference your animation?

humans?

videos?

[thin panther]

comprehensive videos of people performing the actions you need

[odd ember]

I write most of my animations in binary

[thin panther]

and that is more than enough to simulate an animation

[remote meteor]

saying that is like spamming interface on everything just because you heard its good lol

[vagrant flicker]

Thank you very much! I'll try that

[thin panther]

wow going the easy way aren't we?

[magic parcel]

lol its funny to see how coders perceive the use of art and its creation

[thin panther]

I speak as someone who has done 2 sides of the coin

[odd ember]

lol yes silly coders

[magic parcel]

I would love to see your animation, when/if you ever attempt it

[thin panther]

my last course i did was primarily art focused until i decided to learn programming myself

[magic parcel]

nods

[thin panther]

and not once was it ever mentioned, that i had to learn human anatomy to animate something

sure maybe there is some basic element

[magic parcel]

lol

[thin panther]

like you gonna want to know the leg bones connected to the hip bone

[odd ember]

well actually I had to become a doctor before I became an artist just so I could fully understand the anatomy and issues of a human body

[thin panther]

but for a game, you do not need 10000 percent realistic animation with every muscle group simulated, but you sure as hell need good code

[magic parcel]

@odd ember that is actually pretty close

[odd ember]

I hope you realize I was being facetious

[magic parcel]

you were, but in reality, you were not too far off

[remote meteor]

im mean

you actually do study every single part of muscle

before you do animation

lol

[magic parcel]

😛

dont even try to explain to them

its funny how close this conversation is to the original point being made

[odd ember]

I'll have to pose this question to my animator colleagues

get it

pose

[thin panther]

sigh

[remote meteor]

haha yes yes sigma male

[magic parcel]

the study of Human anatomy is a basics in all art, when attempting to create humanoid and bi-pedal creatures

[remote meteor]

i know this chat is dead sometimes

but it doesnt have to be liven up like this

😂

[odd ember]

this is nothing

you should check out what happens in #cpp after hours

[thin panther]

cpp is a scary place

[magic parcel]

In fact, in most colligate based curriculum you will have a mandatory anatomy class.

[thin panther]

i guess my course was just hella weird then

i shall concede defeat

[magic parcel]

the point is, your could make your animation and get away with it, but it would be as handicapped and silly as me doing stats in the game instance 😛

which is my point

[thin panther]

we did so much art and character studies and not once did we cover anatomy

was my course just scuffed

[magic parcel]

probably taught by a highschool teacher who upgraded 😉

highschool "art class" also learns about art

[thin panther]

rip my entire arguement then

[remote meteor]

well there are actually IT courses that doesnt really go through all the basics first

it depends i guess

[odd ember]

I don't know the state of game art courses anymore, but a while back they weren't great

[thin panther]

true but i expected better from higher education lmao

[magic parcel]

right?

[remote meteor]

like "quick way to get you started"

how they make it quick

it to skim through the details

lol

[magic parcel]

my point, has been skewed a few times (notice my art puns too)

[thin panther]

the art puns are killing me

[magic parcel]

im simply saying what you already said (CE)

so, I am actually agreeing with you, while being annoyed that you would say it 😛

[remote meteor]

knowing a little from every part of a game dev process

[magic parcel]

anyway, back to watching this tutorial since getting help from you guys has cost me 1+ hr 😛 when I could have just followed this turd and created the shit i needed

[remote meteor]

does makes things easier though

[thin panther]

well this was all one big waste of time then 😂

[magic parcel]

not really

discourse is important

[thin panther]

brb looking up a word

very true i agree

[magic parcel]

and for my full intent, @odd ember i want to learn these things so that I can create a guide/tutorial that is the "right" way 🙂

[remote meteor]

anyway

for your original question about STATs right

[magic parcel]

oh snap

[remote meteor]

GAS is a good place to start

😅

[magic parcel]

....yes (listens with full attention)

[thin panther]

thats quite noble tbh

[magic parcel]

damn you

[odd ember]

the "right" way already exists. just the type of youtube tutorials you should be looking for aren't pre empted by the word "blueprint"

[magic parcel]

@odd ember i used tutorial 😛

stats + tutorial

UE4... correction

[glass magnet]

Hey yall sorry im still not able to figure out how to move within range of the target.

[magic parcel]

In the military we have clear guides, we call them an SOP. My desire to find something like this for these.... is my goal 🙂

[thin panther]

if i want to make my static member function a BP node, do i just precede it with

UPROPERTY(BlueprintCallable)

[magic parcel]

SOP's are created for anybody, no matter the skill level, to look at something and accomplish the tasking.

[odd ember]

anyway data is malleable and any given project will have different requirements for how to handle data. assuming that you can handle data one way and let that be the only correct way to handle it, would be a fallacy

[magic parcel]

SOP's are vetted by experts in the field, to ensure the accuracy

[odd ember]

yessiree

[thin panther]

i imagine SOP's are extremely important

[odd ember]

or wait

[magic parcel]

would a person know what is going on? no, but could they launch the nuke? yes

[odd ember]

UFUNCTION

not UPROP

but also #cpp creeping in here

[remote meteor]

UFUNCTION

[thin panther]

ah ty for catching that

im classing it as #blueprint cause im making a blueprint node

but also it feels awkward to switch an ongoing question to another channel

[magic parcel]

but seriously... is there a better tutorial i should be looking at? or a better person?

I am watching Ryan

[remote meteor]

its ok 😆 its all #offtopic anyways

[thin panther]

inb4 i get flamed but ryan laley seemed decent out of everyone

[magic parcel]

Ryan Laley**

[odd ember]

give me the intent of what you want to do. not technically implement, but what you want to see in the end

[remote meteor]

you can reference him

but not exactly sometimes

[magic parcel]

I just need player stats that I can use in other areas.

[odd ember]

which other areas

[magic parcel]

I was going to create them as components because of how they will be used

[odd ember]

a stat component is not a bad idea

but let's get the full scope nailed down first

[thin panther]

i mean i am using a game instance for that because they need to go across multiple levels, and i have multiple character classes

[remote meteor]

that persist between persistent level travels

[magic parcel]

@thin panther that is what Ryan says to do

[remote meteor]

hence he used the game instance

[thin panther]

hell thats what im doing

[magic parcel]

but i got flamecasted when I asked here 😛

[odd ember]

the little I've heard about this dude is not great, just FYI

[magic parcel]

so maybe I asked it wrong

[thin panther]

i do need to look into components tho cause they seem useful

[magic parcel]

components are extremely helpful

[odd ember]

components are great

[magic parcel]

its like a mod/addon

[remote meteor]

separate your functionality into components as much as possible

[magic parcel]

attach it to the bp, now that bp can use what the component can do

its like a material function, on the art side

[odd ember]

much like everything there's multiple ways of doing things like these

[magic parcel]

in any case.... if I do the component, how do I create persistency ?

[odd ember]

a stat component would only get flushed if the character it was on got flushed

[remote meteor]

game instance is a legit way if its a single player game

[odd ember]

but in essence what you're after is a save game system

because you want persistent data

[remote meteor]

but its not storing only stats

[magic parcel]

well... sure

that is the BIGGER picture

[remote meteor]

you are storing the whole save game

[thin panther]

say for my instance, I have a bunch of charactersrobot vacuums, that all have different stats, that must persist between level changes, and must be able to be updated in UI and stuff, so a game instance seems to be my best bet, especially seeing as multiple characters need to be destroyed and spawned in a level, and it seems more efficient than loading the data all the time, if i can just fetch it from the instance

[magic parcel]

but I need data to store, first

[remote meteor]

so you can reinitialize from there

[magic parcel]

and structuring that data properly is what I am after

[remote meteor]

the actual runtime usage of data

will be in StatsComponent

for all the calculation and such

[odd ember]

that' being said, a stat component is correct. if you can get to use seamless travel, game mode has a list of seamless travel actors that aren't flushed when switching between levels

[regal igloo]

I need help with setup up saving my talent tree. I tired setting it up but i need talents to be saved in main menu which will then be loaded onto character when i load into game. I am making a rogue like game. So players won't have access to talent tree in game just in Main menu. After loading into game then i want to pull the saved talent data to set the player stats.

I am having trouble setup up the saving of talents. Can anyone help I am available for voice chat.

[remote meteor]

then player state is a good place

[magic parcel]

thank you

[odd ember]

player state still gets flushed

[remote meteor]

what doesnt get flush again

player controller?

[odd ember]

game instance

[remote meteor]

in seamless travel

[odd ember]

I think you have to enable it first but by default it should be game mode only that doesn't get flushed during seamless

although I've heard people say controller shouldn't be flushed either

it's not my experience though

[magic parcel]

so....

[remote meteor]

not sure, will look later

[magic parcel]

1. dont follow ryan

[magic parcel]

2. use component (like i said 1hr ago)

3. thank you all

[thin panther]

isn't seamless travel a multiplayer thing though

[remote meteor]

dont exactly follow ryan, if you feel a doubt

[odd ember]

nope

seamless is the way to change levels correctly

[thin panther]

But will loading screens still work iwht seamless travel

[odd ember]

yes

[thin panther]

and whats wrong with open level

[magic parcel]

one last thing..... if I end up making tutorials, can I ask you guys for peer review?

so i dont end up being a turd that people ask about, and then you burn them for it?

[odd ember]

doesn't allow for seamless travel of actors

[magic parcel]

:p

[thin panther]

Ah but I don't necessarily want seamless travel of actors, I want them to be reinstantiated

[odd ember]

no offense but I am not going to watch tutorials. but if you can summarize what you want to explain then I can read that

[thin panther]

the only one that could be potentially useful to travel seamlessly is the radio system

[magic parcel]

no offense taken 😛 i was mostly make a joke on the situation at hand

🙂

you gents enjoy, I do appreciate your time

im going to go fumble fuck my way through these components

[thin panther]

enjoy!

[remote meteor]

seamless travel is basically using the command ServerTravel <MapName> right?

[odd ember]

oof I can't actually remember how to invoke it in BP

server travel does sound correct though

[magic parcel]

its level

changelevel

[remote meteor]

was looking around for it 😂

[magic parcel]

and it creates a seamless travel

[odd ember]

you'll need to have a seamless travel level setup as well

as an intermediate point between the level being loaded and the one being unloaded

there are options for this in the project settings I believe

[magic parcel]

correction, open level

[thin panther]

open level is the seamless travel

so open level isnt bad

great i can continue on my day

[odd ember]

ugh I'll actually have to check this

[remote meteor]

i really need to get out of this Load Level Instance way of doing things before shit happens 😂

Open Level changes the persitent level

[odd ember]

forcing me into unreal on my day off 😔

[remote meteor]

its not seamless

[magic parcel]

i thought it was seamless?

[thin panther]

so is it the streaming levels?

cause it doesnt seem like it would be

[magic parcel]

streaming levels is different

[thin panther]

thought it was

[magic parcel]

streaming is 'in line'

seamless travel changes the level but takes the data with you

[remote meteor]

actually, im not very sure what exactly entitles as seamless travel

[magic parcel]

(if I understood it correctly when my coders were explaining it before)

[odd ember]

void UGameplayStatics::OpenLevel(const UObject* WorldContextObject, FName LevelName, bool bAbsolute, FString Options)
{
    UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull);
    if (World == nullptr)
    {
        return;
    }

    const ETravelType TravelType = (bAbsolute ? TRAVEL_Absolute : TRAVEL_Relative);
    FWorldContext &WorldContext = GEngine->GetWorldContextFromWorldChecked(World);
    FString Cmd = LevelName.ToString();
    if (Options.Len() > 0)
    {
        Cmd += FString(TEXT("?")) + Options;
    }
    FURL TestURL(&WorldContext.LastURL, *Cmd, TravelType);
    if (TestURL.IsLocalInternal())
    {
        // make sure the file exists if we are opening a local file
        if (!GEngine->MakeSureMapNameIsValid(TestURL.Map))
        {
            UE_LOG(LogLevel, Warning, TEXT("WARNING: The map '%s' does not exist."), *TestURL.Map);
        }
    }

    GEngine->SetClientTravel( World, *Cmd, TravelType );
}```

[magic parcel]

so, yes, open level 😛

[thin panther]

ah good

[magic parcel]

does a dance

[odd ember]

whereas

[magic parcel]

do i get a certificate?

[thin panther]

open level was the only way i knew of anyway

[magic parcel]

when I complete courses online for coding i get a certificate...

[odd ember]

seamless travel is simply

GetWorld()->SeamlessTravel(levelName)```

[magic parcel]

oh ... trucks

CE with the switch

[thin panther]

so it is c++

that bait n switch

eh i can live without seamless travel

[magic parcel]

last time I was doing this, was on a project 10 years ago

[thin panther]

me and my game instance are fine

[magic parcel]

and it was cpp based 😦 so makes sense

[remote meteor]

i was figuring this because my requirement was

bgm to persist through the loading screen between levels

[thin panther]

you see i would like that, but eh its fine without it

[remote meteor]

well its my boss's requirements so i have to find ways 😂

[thin panther]

rip

[odd ember]

so the difference between normal travel and seamless is that you get that intermediate point

where you move persistent actors to

while unloading the previous level and loading the next

[thin panther]

smh 5head just open level > open level, ez intermediate point

for legal reasons that was a joke

it sounds so nice

but it also sounds like a pain

[magic parcel]

https://www.youtube.com/watch?v=Kj2p0Iahn_4

is this okay?

or trash

[thin panther]

but i could also just make a node for it and then never have to do it again

[odd ember]

just

make your own component

[magic parcel]

it looks okay, from my quick scrub

[odd ember]

do it the hard way

[magic parcel]

i am

[odd ember]

fail

[magic parcel]

i did

[odd ember]

cry

[magic parcel]

current emotion, already

[odd ember]

start over but with more experience

[remote meteor]

idk but seeing the variables one by one in the component

[magic parcel]

I have a present for you

[thin panther]

smh c++ is the hard way cause it needs typing

[remote meteor]

makes me have heart anxiety

when i want to initialize the component

[magic parcel]

https://tenor.com/view/jesus-you-need-jesus-thats-what-you-need-gif-11003249

[remote meteor]

now thats the time i would make the stats into structs

[odd ember]

well at least I don't need a diet

[magic parcel]

🇦🇺

[thin panther]

could i theoretically make my own function for seamless travel then never have to touch it again if i expose to bp

[remote meteor]

https://tenor.com/view/i-will-send-you-to-jesus-jesus-emotional-damage-emotional-damage-meme-meme-gif-24543806

[thin panther]

cause i do like bp

[odd ember]

that is within the realm of possibility yes

[thin panther]

but some groundwork in c++ i am not entirely adverse to

[magic parcel]

im going to watch this tutorial

😛

out of spite

[thin panther]

unless it is serialization, which makes me cry so no

[odd ember]

this is how I started doing cpp "oh hey I'll just expose these things"

next thing I know I'm layering subsystems on top of each other

[thin panther]

the main reason i am not using c++, blueprints are just too convenient

almost a curse

[odd ember]

yes but subsystems

[remote meteor]

sub systems

is a bless

🙏

[odd ember]

subsystems are godlike

[thin panther]

dare i ask what sub systems are

[odd ember]

a system

but sub

[remote meteor]

its like singleton

[thin panther]

thank you CE, very cool

[remote meteor]

but modern

[odd ember]

yea a singleton that doesn't go all fuccboi on you

easily exposed to BP

you can call it anywhere

I gotta get started on my weather subsystem as well 😔

[thin panther]

well i guess its time to make these structs, then cry for a bit because i vowed no unreal c++ cause it looks scary

[odd ember]

unreal cpp is a gentle giant

you don't really have to worry about memory management

[thin panther]

really it looks way worse than std

[remote meteor]

as long you dont go java pepega and use the new keyword

😅

[thin panther]

ew

new

[odd ember]

I forgot new existed

[thin panther]

first lesson of c++ in uni we were told if i see new you fail the assignment

new is one of those words for me

like moist

[remote meteor]

it has its use.. but 99.999% of the time you wont need it

[thin panther]

nah looks fine to me wdym

[odd ember]

https://tenor.com/view/yamero-stop-it-stop-glitch-bird-gif-15552622

[thin panther]

yeah i mean it has like 1 use... maybe

for making my c++ struct can i just use the empty file or is there any auto generated garbo i need

[odd ember]

you need some macros

[spark steppe]

if it's a plain c++ struct go ahead, if it's a USTRUCT you need garbo

[odd ember]

like GENERATED_BODY()

but also

#cpp

[thin panther]

ugh fiiiiiiiine

[spark steppe]

just reused his term

[trim matrix]

Is there any way to change which Audio Input device my game should use. I can't find any way to get it to use anything except for Windows default device

[odd ember]

probably a good question for #audio

[magic parcel]

@odd ember can you explain something to me....

why isvalid a thing?

[odd ember]

imagine

[magic parcel]

shouldnt the BP system know that it is valid, based on the fact that i pulled the reference from a pin?

[odd ember]

that you can have variables that are empty

let's say a trigger can act on something going through the trigger

[magic parcel]

so this is nullpointers?

[odd ember]

but obviously if the trigger is empty

there is nothing to act on

yes

[magic parcel]

@white lynx i thought this was C++

so no GC

GC is only in C#

or, that was my understanding

k

well fuck

i added a isValid, and now the entire shit works

so annoying 😛

[odd ember]

I imagine those are the same people prefering linux over a real OS

[magic parcel]

so a quick is valid, ensure that no nullpointers exist

so... as good practice

i should always use isValid when making a cast?

[odd ember]

I mean I wear the cape of NIH but not to the point of ridicule

[magic parcel]

or, prior to the cast

well if i just use the cast, it doesnt work

[odd ember]

you should do it when you cannot ascertain whether or not a variable will always be valid

not all the time

[magic parcel]

@trim matrix you said, use isvalid adn then didnt say where or what 😛

i had my code buddy wake up and stream with me to explain it

@odd ember cool

you were def right

well, i didnt wake him up, he woke up, then asked what was wrong 😛

so... onto another interesting bit

none of this worked, without putting a delay

why?

if you remove the delay on the event construct, it doesnt work and never fires because it cant get the player ref

[odd ember]

race conditions

[magic parcel]

widgets load faster?

[odd ember]

actors are loaded in unordered

or I should say objects are

[magic parcel]

delay seems hacky

[odd ember]

it is

[magic parcel]

is there a better method to do this?

[odd ember]

spawn the widget from your player controller and keep a reference

then you can assert that the player controller exists before the widget is spawned

[magic parcel]

so, im already doing that... i think

wait one, ill check

yeah

so onPossessed i am spawning the main Hud

the weaponWidget is a child of that, nested in the mainHud

[odd ember]

switch out your reference of GetPlayerController to GetOwner

[magic parcel]

hm...

[odd ember]

or wait

you're using player character

[magic parcel]

i should call this on the controller?

probably in this area

[odd ember]

do GetOwner->CastToController->GetControlledPawn->CastToYourPawn

[magic parcel]

k

[odd ember]

inside your widget

[magic parcel]

ah

interestingly that kinda made sense

thanks

[hearty barn]

nope File->Import into level

[odd ember]

understanding what works during runtime and when you can expect race conditions and how to assert that they don't occur is a big part of the architecture as well

a lot of patterns exist to mitigate these kinds of issues

[magic parcel]

well, that is why i want to learn the right way

😉

once I finally grasp this shit, I promise I will make detailed tutorials for my artist buddies 😛 so we continue to raid this channel and annoy you

[odd ember]

the two most common patterns that will help you understand this is MVC and the observer pattern

the MVC in this case also doubles as a game design problem

[odd ember]

yes

that's true

[magic parcel]

so... i should be doing WPF

?

lol

[odd ember]

no

[magic parcel]

lmao

[odd ember]

but if you gain an understanding of the pattern you can start overlaying those into architecture

[magic parcel]

k

[odd ember]

now unreal kind of helps you out since it's already got a class called PlayerController

[magic parcel]

well, the pattern isnt hard to grasp

but application, i assume, is

[odd ember]

yes

so the the controller receives input and distributes it

the player character is most often the model

the view is the camera

in a traditional sense

[magic parcel]

so

why would code reside in the controller vs the model

[odd ember]

special cases. the controller possess the pawn

[magic parcel]

shouldnt all the important bits be in the controller?

[odd ember]

what if there are more pawns to possess, and each of those have different functionality?

[magic parcel]

sure

but HUD stuff is def common placed

[odd ember]

HUD stuff is generally placed in the player controller

or the hud class itself

[magic parcel]

interesting

[odd ember]

which again is linked in the player controller

[magic parcel]

very informative, thank you

I appreciate the time spent to barney it for me

[odd ember]

I mean this is why I keep going on about OOP stuff

it's all there

and none of the blueprint youtubers dare even mention it

[magic parcel]

sure, and I can tell you I have read it, took a class on it, doesnt mean I understand how that corelates.

my grasp of it, is not even close to what I should have

[odd ember]

well a single class isn't going to help you understand it

like I said it takes years

[magic parcel]

sure isnt

this is a sub hobby, of a hobby 😛

I have 20 years in the military as an IT

[odd ember]

but IT isn't the same as system architect

[magic parcel]

I have Net+, SEC+, CEH, CCNA, etc

its all derived from the same stuff, sure

[odd ember]

I don't even know what half of those are

[magic parcel]

but application is where it matters

well, thats kinda my point

😛

[odd ember]

I don't think it is. IT cares about infrastructure

[magic parcel]

computers are such a vast swath of information.

i didnt learn about OOP for any of those certs

nor have I used OOP in any of my daily actions

not in the sense of programming it

Layer 7 vs Layer 5 😛

[odd ember]

I wouldn't trust the IT department of my company (or really, any company) to be doing any kind of code work involving something as complex as a game engine architecture

[magic parcel]

nods agreed

I dont get paid to code games

[odd ember]

neither do I

[magic parcel]

I was saying that, your point to years

My experience and time is in other areas

[odd ember]

yes but it's comparing apples to oranges

[magic parcel]

and my hobby, to that job is art

and my hobby to that hobby

is coding (now)

[odd ember]

IT != system architecture

that is what I want to get to

[magic parcel]

i was not saying it is

I get that

you == me

😛

I am literally making the same point you are, but from a different angle

the hang up is the words

and personal application of the meaning

anwyay

thanks for the time, that is all I am saying

[odd ember]

there is no personal application here. this is just how these things work

I'm not saying this from the point of view of "me"

[magic parcel]

eh

your issue is with know

"know"

"you shoudl know OOP"

[odd ember]

well no

you said you knew OOP

I said "go study it"

[magic parcel]

indeed

so perhaps the phrase "gain further understanding because your current state seems lacking"

[odd ember]

here's a website that is useful: https://gameprogrammingpatterns.com/contents.html

[magic parcel]

that would be super harsh 😛

but more accurate, no?

[odd ember]

correct

[magic parcel]

so the funny part is, this correlates to the argument I was making before 😛

all good

again, I do appreciate the time

i have saved the link

[brazen merlin]

interesting... 🤔

[odd ember]

understanding concepts like object responsibility, (de)coupling, encapsulation and how to apply them across different scales is where you will want to go

because writing code is one thing, but writing code that doesn't bite you in the behind later is entirely another

[main lake]

Is it possible to put multiple variables in a category at once instead of selecting each variable one by one and moving it to the category I want ?

[mortal nacelle]

Hi all, noob question. How do you edit a nested subfield of a struct easily? For example, I have a ButtonStyle struct. I want to change it's image for all three modes (normal, hovered, pressed).

The only option I can think of is to do a new Make ButtonStyle and copy over every field. But there are like 25+ of them. I just wonder if there is a better way. In code it would be simple.

[odd ember]

if you scroll up we've just had a very long discussion over why blueprint structs generally should be read only

[mortal nacelle]

ok. perhaps i should rephrase the problem then. how should i handle changing the button image dynamically?

[odd ember]

I think more context is necessary

[mortal nacelle]

I’ve got a skill tree where I need to set a bunch of button images dynamically depending on your class, from a data table

[odd ember]

that sounds like you don't need to set them on a struct, but rather read from a struct

[mortal nacelle]

Well I only wanted to save the texture in the data table. And merge it with the normal/hover/pressed tint settings which are invariant

[odd ember]

if they are invariant just have a base button class where those are already set?

[mild crystal]

hello, i need help. how do i set up a animation transition. for exemple i pressed left mouse button to start dancing and when i realease it will back to idle. But i want to only back to idle after the animation played (not while is playing) because i pressed left mouse to shoot for exemple and if i realeased mid animation it will just back to idle without completing the animation. Anyone know how to fix?

[odd ember]

sounds like an #animation question

[mild crystal]

no coz i set it on blueprint but whatever i put it there

[odd ember]

ok well if you know better good luck

[glass magnet]

hey yall im still trying to figure out my attack range i dont quite understand how to use the horizontal distance to justify that

[undone willow]

yo anyone know how to have one character take input from two controllers?]

[vital aspen]

when adding a item to an array like this

I can't seem to change or add to the Qty in that slot. anyone have an idea.

[maiden wadi]

You're just getting whatever is specified in that struct and adding one, then adding it to an unrelated array.

Is this for something like picking up an item and adding it to the first item that matches in the inventory?

[vital aspen]

No, This just adds it to the inventory. The rest of it I haven't figure out how to do yet.

when I add just 1. I can't get the number under the item to change from a 0 to a 1 and so on

[maiden wadi]

Cause you're adding a new struct, not modifying the one already there.

[vital aspen]

Oh, so is there a way to modify it.

[maiden wadi]

Sure. But it depends on how you can look up that same item without the quantity.

[vital aspen]

This is all I have, The video tutorials I have been watching leave out too much detail.

[maiden wadi]

Most times your items will have an identifier. An integer, or FName, or GameplayTag that points to what the item is. Like Apple could have
interger ID 813
FName InventoryApple
GameplayTag Inventory.Item.Apple

You use those to compare if it's the same type. So when your pickup says "add this to inventory", you can iterate over your inventory looking for the item type that the pickup is, and if itemtype == array index item type, then add pickup quantity to index quantity

You also use this same identifier to look up static data from tables or data assets like the item's Icon, localized name, etc.

[hollow inlet]

how can I.. when I spawn an Actor, I want to set a simple string variable on it, can I pass that in as a constructor sort of argument?

[maiden wadi]

Make the string on the class InstanceEditable, ExposedOnSpawn

Refresh the Spawn node, and it should display there once that class is selected.

[hollow inlet]

i see, thank you

[gentle urchin]

How would you do a gameplaytag queue? 😄

[maiden wadi]

Queue as in?

[gentle urchin]

A que of items to be delivered

Multple entries of the same tag

[maiden wadi]

Depends. Probably a TMap of Tag/Quantity. Alternatively if they're not stackable, just an array of tags. If they're not stackable, and are all unique, just a TagContainer.

[dawn gazelle]

If this is a local multiplayer game and both player controllers can get reference to the character you want to control, then it's just a matter of feeding commands from the player controller to the character.
If it's an online multiplayer game, it would be similar but you would first need to RPC the commands to the server and have the server pass along the controls to the character.

[maiden wadi]

Also depends if it's networked. If you need the data to show over network, an array of Tag/Integer maybe.

[gentle urchin]

Hmm. Array of struct makes sense. Carriers start out with only 1 held item but can be upgraded. Having it in a struct like that makes it easy to keep track of related requests going in the same direction

Tyty

Not networked at all

[maiden wadi]

I have a "Database" struct class I made. Very small plugin. Just has a few structs on it and a small library at the moment. Literally just has a struct that has six other structs. The other structs are just a Tag and another value. It's like Tag/Integer, Tag/Float, Tag/Byte, Tag/String, Tag/FName, Tag/FVector. So I can also use the TaggedInteger struct anywhere else like an array on it's own too. 😄 Love it.

[gentle urchin]

Ohh. Interesting !

Knowing myself im probably interested in multiplayer down the line but i really try hard to not go out of scope untill ever 😂

Its just headaches and reasons to start over again anyways

[versed sun]

"I will just make a game and do the multiplayer later" -Me

[gentle urchin]

Its just

[versed sun]

it didn't work..

[gentle urchin]

Multiplayer adds so much to it

[hollow inlet]

is there a trick to "refresh" it?

[maiden wadi]

Just right click and refresh node

[gentle urchin]

Suddenly you stray so far from your original concept that you're competing with regular RTS's like SC and AoE and whatnot

[hollow inlet]

oh! thank you

[velvet dagger]

How can I change the shape of the capsule collision?

[maiden wadi]

Like scaling it, or turning it into a cube?

[velvet dagger]

Turn it into a cube :)

[maiden wadi]

For the Character class?

[velvet dagger]

Mhmmm

[maiden wadi]

Access Denied.

[velvet dagger]

Aw :(

[maiden wadi]

It's an inherited component. Can't change it. If you need a different shape, you would need to create your own character class. Which involves a lot of C++ and a major headache integrating the character movement component.

Or you can create your own Pawn class, and your own Movement Component from something like FloatingPawnMovement. If your game is singleplayer, making a movement component is incredibly simple. CMC is mostly useful for it's replays and networking.

[velvet dagger]

Daaang, sounds like something I'll need to deal with waaay later

[maiden wadi]

If it makes you feel any better. A lot of games make animals and such with the character class.

Their AI handling does some extra checks for movement. It's only downside are heads sticking through walls.

[trim matrix]

Hey guys, my enemy AI is running on spot and not running towards the player, what is the reason for that?

[flat bison]

hey guys, when i press play i want to look through the camera i placed but it does not

i can directly get auto active for player but then i don't need BP for that, i want to do it with bp, can someone help

[gentle urchin]

the node you're looking for is "Set View Target with blend"

[fleet cobalt]

easy question is there command that stops specific sound, I have made when I hold w sound loop starts playing and I want it to stop on release

[upper mortar]

I am working on edge scrolling for an RTS camera, any idea why Get Viewport Size returns wrong screen width and height. Get Mouse Position on Viewport keeps returning larger than my screen width.

[gentle urchin]

you gotta include scaling

[flat bison]

getting none

by the way its level blueprint

if im doing it correct

[gentle urchin]

i know

i'd say no but 😄 who cares

search for the node without the context of the camera

without context sensitive

[maiden wadi]

Sounds like your animation is still playing, not that the character is running anywhere. You likely forgot to set it back to the idle state in the anim blueprint's state machine when speed<5 or something.

[undone willow]

how do I make an actor temporarily gone from the game?

[gentle urchin]

Set visibility

[undone willow]

i tried set hidden but they are still there physicly

ah visibiliy

[gentle urchin]

disable collision

you gotta do both 😛

[trim matrix]

Oki, I will look into that. Thank you!

[undone willow]

ok so a visibility node and a collosion node

[gentle urchin]

yepp

[undone willow]

is it this one?

[gentle urchin]

you were right about the first node

[flat bison]

well i got the node now but im getting an error

actually its okay , thanks for answerin

[gentle urchin]

the node tells you the context it needs in the header

[fleet cobalt]

how do stop sound from playing? I cant find a node for that

[gentle urchin]

since im procastinating

[flat bison]

yea but i don't have a character setted up yet

[flat bison]

it asks a target

and then a new target

i just want to start with the cam i placed

[gentle urchin]

The header tells you both the function name and the target class

well

[undone willow]

oh right

[gentle urchin]

the player is gonna be a pawn ,

likely a character

[flat bison]

uhum

[gentle urchin]

so you can probably get away with get player char 😄

sry, get player controller*

since thats.. well given

[flat bison]

oh so i need to set up a character BP

then connect it to target ?

[gentle urchin]

All you need is a controller

which you have

and a new view target

which you've made

[hollow inlet]

I added a Text Render Component to an actor.. but I can't bind the text value to anything?

[gentle urchin]

viewtarget is of the type "Actor" as description says

[flat bison]

wait it worked

[gentle urchin]

so any actor with a camera will more or less just work

[flat bison]

thanks

but i didnt understand how it works

[gentle urchin]

there is always a player controller

it comes with the engine

part of the framework

[flat bison]

what was the nodes i created then

[gentle urchin]

then you just feed it with a reference to some actor with a camera

the node is a function in the player controller

[upper mortar]

Why does Get Viewport Size return X of ~1300 while Get Mouse Position on Viewport returns up to ~1600

[gentle urchin]

which also is part of the framework

[gentle urchin]

lack of scale

[flat bison]

but when i set up a character BP, i will include a camera in the character blueprint right ?

not from level blueprint

[gentle urchin]

correct

so whenever you wanna go back

you can just have "get player char" as the new view target

[upper mortar]

Get Viewport Scale?

[gentle urchin]

Correct

[flat bison]

thanks for helping squize

im a newbie :/

kinda hard

[gentle urchin]

take your time, play around doing simple stuff

get to know the framework

[flat bison]

but i didnt get something

[gentle urchin]

the thousand + 1 classes that already exists 😄

[flat bison]

if there is event begin play node

why it just doesnt work when i click on play it gets the camera

instead we are getting the controller

and player character

[gentle urchin]

well you need to tell the engine who you want to set the viewtarget for

[flat bison]

oooh

[gentle urchin]

since there could be several players and playercontrollers

[flat bison]

oh so target input is for this right ?

[gentle urchin]

Target is who

[flat bison]

target is .. my new cam ?

[gentle urchin]

New ViewTarget is the camera 😄

or an actor with a camera

[flat bison]

that is where i am confusing lol

there are two targets i am understanding

target is my cam, okay but why is there a new target

[upper mortar]

thats working now, Thanks. Thought you where talking to someone else when you said that earlier

[gentle urchin]

Target is not your cam

Target is like your Screen or whatever

while New View Target is "which camera do i wanna watch on my screen"

[flat bison]

can we make it

target is this character

new target is this camera

[gentle urchin]

no

because the character

may have a camera

but the character is not using it

the player controller is using it

Sorta..

if you wanna dive deeper its really a

This is all part of the framework tho 😄

tons of classes to get familiar with

[hollow inlet]

How can I set or bind this value?

[flat bison]

why are we getting SET instead of Get

because the engine has its default cam actor ?

[hollow inlet]

in a Text Render Component?

i feel like i'm missing something so obvious

[gentle urchin]

You're not asking "who's camera are you currently looking at?"
you're saying "Look at this camera, now (lerped over blendtime)!"

[flat bison]

😭

too hard

[gentle urchin]

baby steps 😛

[flat bison]

da baby will get up

[gentle urchin]

everyone wants to run after their first hour

[flat bison]

how long did it take you to learn bp

maybe its essentials

[gentle urchin]

do i really know bp?

[flat bison]

are we alive :d ?

are we living in a simulation

[gentle urchin]

I've been at it for about 5 years on a hobby basis

[flat bison]

NOOO

[gentle urchin]

If only I could go back and start with the knowledge i have today ...

which is not much, but its more than i had atleast

5 years and i still cant design a level even if my life depends on it 😄

[flat bison]

but isnt it modelling ?

[gentle urchin]

level design yeah

sure, its a very different topic from bp / programming

[flat bison]

well , can a modeller learn blueprinting

i should

[gentle urchin]

Sure

takes time, but very doable

[trim matrix]

Idk how people do 3d modeling

[flat bison]

its pretty easy

[gentle urchin]

I'd probably manage to make it prettier by programming some mesh than doing it myself

[trim matrix]

Programming 100% easier then modeling

[flat bison]

but not the organic modelling

[trim matrix]

[hollow inlet]

thanks

[flat bison]

Modelling %100 easier than programming 😭

[trim matrix]

[flat bison]

so there are people that don't know how to model ...

at least, now i don't have to be sad if i can't program

[gentle urchin]

I made a chest once

it even had morph keys

and i tried to "model" within the engine itself 😄

cuz atleast unreal brushes get me

[trim matrix]

[flat bison]

I MADE THIS !

[gentle urchin]

fight

[spice smelt]

quick question, is there a spaceship operator equivalent switch for blueprints?

[trim matrix]

I think squize is better

[pure relic]

as a 3d modeler by trade, i think the opposite

[flat bison]

brutality

[gentle urchin]

I did this a while ago

[flat bison]

squize wins

[gentle urchin]

xD

all brushes

[flat bison]

same bro same

[gentle urchin]

even the damn door details

[flat bison]

round 2 squize !

oh ...

[trim matrix]

Spaceship operator equivalent switch? What’s that

[pure relic]

here's a doodle i did

[flat bison]

TAKE THIS

[flat bison]

oh god

[gentle urchin]

this is the chest i talked about

[dawn gazelle]

Behold!

[gentle urchin]

blender all the way

[pure relic]

getting off topic tho, i do have a question for this channel actually haha

[spice smelt]

C++20 introduced the spaceship operator

a <=> b

it returns -1 if a < b, 0 if a == b and 1 if a > b

[flat bison]

O MY GOD

[trim matrix]

I see, not sure

[flat bison]

looks good tho .d

[gentle urchin]

xD

It was even animated

blueprint related!

[trim matrix]

You can use compare int, you can also easiliy program that yourself in a function library

[pure relic]

I'm unable to pull my 4th array index, and im not sure why still... keeps returning 0-3 and im not sure why

That BP is to check to see if the array has been chosen before, if so then replaces with a new one

[spice smelt]

oh that's exactly what i wanted, thanks!

[spice smelt]

yeah i prefer to use builtin stuff rather than rewriting what already exist, just didnt know how it was called to find it

[dawn gazelle]

Further to Squize's post, use Random Integer in Range with last index hooked into max, and min set to 0.

[gentle urchin]

The node is old

made before last index existed

so its made for "length"

thus the -1 notation

[serene robin]

I'm frantically searching for a way to map the left and right trigger (R2 and L2 - xbox controller) of my third person character to rotate on the Y in place. Right trigger (R2) rotate the character around to the right (in place), Left trigger (L2) to rotate around to the left (in place). Ideally also it would be awesome to be able to rotate in place on the X axis as well (with xbox controller (maybe L1 and R1). Imagine my character as a cube and not a mannequin. Any help really appreciated. I'm trying to make a puppet-type head that moves around a scene, but also can be rotated in place. Could really use the insight. Could even pay a few dollars for the lesson in how. I have a video sample of what I'm trying to accomplish. You'll see, i'm moving my "guy" around. but when i'm idle, i'd love to be able to then use R2 and L2, to just rotate in place (like looking left and right or up and down).

[hearty barn]

yeah apparently it keeps both the pivot point and the transform so my life is way easier now lmao

[maiden wadi]

Also if you're on later UE4 versions. You can get RandomArrayItemFromStream.

[gentle urchin]

yeah those are also new

"new"

[maiden wadi]

I think they started showing up in 4.26

[gentle urchin]

Was about time 😄

[pure relic]

@gentle urchin @dawn gazelle is there a way I can link my world seed into how the index is chosen?

[gentle urchin]

RandomArrayItemFromStream

[maiden wadi]

Still waiting for GetLocalPlayerController to be a default.

[pure relic]

(also that worked using random integer range, thanks)

im on 4.25 D:

[gentle urchin]

random int in range from stream ^

its right there when you search for it 😛

[pure relic]

oh fuck me, thank you

[pure relic]

i have eyes i promise

❤️

[maiden wadi]

Liar.

[timber knoll]

Save both axisvalues (L2 and R2), then simply do (R2-L2)rotationSpeedDeltaTime and plug that into yaw for AddRotation

[gentle urchin]

I've always seen a big fat A on the ocean on your pic. Not sure what it actually is

Iknow, it doesnt make sense

[timber knoll]

Where rotationSpeed is however fast you want it to spin

[maiden wadi]

Haha. That's literally just a TextRender in the ShooterGame scene.

[pure relic]

PROGRAMMING SO SO COOL (it worked im happy haha)

[flat bison]

Hey squize, can i add you in friends

[gentle urchin]

I dont have time for such

[tranquil abyss]

Does anyone know why this compiler error is happening, This literally was working a few hours ago and ive changed nothing.

[gentle urchin]

I'm always busy either working on the project or procrastinating here in the slackers server

[flat bison]

I may need help sometimes

That's why i want to add you

Ur a good person

[pure relic]

One more question. Can someone explain how to cast from one blueprint -> another for me? I understand im casting a class to a blueprint, but im unsure how to CALL it from my target blueprint

Was up till 3am trying to understand that and I almost got it but to no avail

[gentle urchin]

Casting is typechecking a reference , and lets you treat it as such if it succeeds

[serene robin]

Thank you so much for reading and responding. I'm very very new to the blueprint side of unreal. Essentially learning from the help of others on this. I'm a designer and media creator so figuring this out has been fun and challenging. Could you expand a bit visually on setting up these parameters. I basically got as far as I did in the standard third person blueprint. Is this where I add your explanation. My sincere thanks in advance. This is for a tradeshow booth and hoping to really wow a client.

[pure relic]

Yes, it always comes back as failed for me. I'm not sure how to identify it was (in this case) my red chararacter

[gentle urchin]

You somehow gotta get that reference tho. Usually by overlaps/traces/interactions of other kinds

Easiest way to just check the raw type of some reference is to print its display name

If you're not certain about it , or it fails for no obvious reason

[timber knoll]

I’m not at my computer sadly, but I can write it down in simpler steps I guess

[pure relic]

the end goal is to spawn one of four characters based on a random world seed. red blue green or yellow.

So a beginoverlap would then be able to call my class im defining?

[timber knoll]

Start with setting up the input for both buttons under axis input

[gentle urchin]

In your scenario you'd probably just have a master character class which all 4 classes derive from @pure relic

you wouldnt need to cast the class at all

casting also doesnt change anything, it just checks if it already is , and if so, let you proceed 😛 sort of

My explanation probably just adds junk to the pile here ... someone step in xD

[timber knoll]

Then inside your character blueprint you want to create 2 floats, and store the input (nodes named after the input you added, which will have AxisValue pins: use these pins to set the float)

[serene robin]

Only if you have time. I really appreciate it and doesn't have to be immediately but if you can help me solve, I'd be extremely grateful.

[maiden wadi]

I'd post my recent blog writeups on casting. But I'm not sure if they'll be much help. 😄 I feel like I got a little off point. Slightly more technical than tutorial.

[gentle urchin]

did you do one?

I should read it

😄

just to get a better feeling about the memory part

hope you touched on that

[maiden wadi]

Yeah, started a free one for now. Really need to get more structure how what I'm writing. 😄

[maiden wadi]

Try this. Later part has an example and points about class assets and how to use them. Chairplanes and stuff.
https://brandtborges.wixsite.com/authaer/post/casting-performance-concerns-in-unreal

[gentle urchin]

Oh sweet. I like free stuff!

[pure relic]

Sorry, I still dont fully understand. I will need to have a master character class, but how does that master class call my result of which character to choose?

The lightbulb hasn't clicked yet for me haha

[gentle urchin]

By having a master class you likely dont have to care which one of them was picked (the class returned is the picked one , and its removed from the array, so what more would you need to know?)

[dawn gazelle]

My guess would be your "Equipped Weapon" variable is set as type "Object".

[gentle urchin]

Solid guess

[tranquil abyss]

weird thing is.. it just started working

[pure relic]

I'm not explaining correctly I think.
I'm trying to get my character blueprint to show up as the child

and im trying to get my chosen character result the class choice to show up

[tranquil abyss]

😕

[velvet dagger]

How can I make force feedback that decreases in intensity the farther away you are from the source?

[gentle urchin]

You'd probably want to use part of the GameMode overrideable events then and manually spawn the type picked by the player during level startup

Regarding casting in itself, the link Authaer posted is a good place to start!

[pure relic]

Oh fantastic. Sorry Authaer I thought that was directed at someone else, thanks for that link.

[maiden wadi]

There are a couple of other casting posts on the blog part too. Goes into better detail about casting itself rather than performance stuff.

[pure relic]

I'll take a crack at this and try to figure it out, thanks a bunch

[gentle urchin]

I really gotta check out more parts of the toolbox provided by epic..

SizeMap of the bp, never ever seen or used this before

[maiden wadi]

😄 Useful tool for making sure you're not messing with heavy classes when you shouldn't.

[gentle urchin]

So when should I be worried? 😄

a few hundred MB ?

[dawn gazelle]

It looks like you're supposed to be able to create attenuation settings for force feedback but I don't see how to create them at all... I did find this which would allow you to set an attenuation on a feedback effect.

[maiden wadi]

Depends on your release platform. Also depends on the classes in question. If the large class in question is always loaded with the things that make it so large, it's a pointless consideration.

[gentle urchin]

Makes sense

[velvet dagger]

Tysm :)))

[maiden wadi]

That's why I went with a spawner of different asset like classes as an example. Mind went to games like FarCry. Where there are many different vehicle types

[gentle urchin]

reading intensely

very informative !

[vital aspen]

@maiden wadi Sorry I got pulled away from my PC. I under stand what your saying. See that's not what I'm trying to do. I need a way to update the Qty Value in the array. I did find out that's what the "Set Array Elem" does. How ever that still doesn't work.

After I add a to the Qty. I then can add other functions to do other things. Like Add To Stack and Find Empty Slot and so on.

[maiden wadi]

You have to pause your current thinking for a moment. You need a way to find the same itemtype in the inventory first. Without that key, you can't know which inventory index to add to.

Your Adding quantity and adding to stack are the same thing.

Also recommend functions directly in the inventory for ANYTHING that modifies it. Keep it encapsulated, don't modify it outside of itself. This will let you call bindings to update UI and stuff much easier.

[vital aspen]

Ok, first off, It doesn't know that anyway. It should add each Item into the array with a Qty of 1. That way I can work with it. Other then that, I can't do what you want me to do. I'm talking about a new item into the inventory. With a Qty of 1

[maiden wadi]

In that case, what you've done should work fine. So what is the zero that you expected to change to one earlier?

[lost oracle]

Hey everyone, how do i add touch input to my FPS pc project in unreal 4.26. I have tried changing target hardware to mobile and enabled use mouse on touch and always show touch interface but still the joysticks are not moving my character.

[vital aspen]

Look at this

when I added these items in, They should have the 1 at the bottom of each slot

[maiden wadi]

And you're pulling this info directly from your inventory's struct's quantity?

[vital aspen]

that's what I'm using to get that value

[maiden wadi]

Put a print there and print the integer. See if it spams your screen with zeros. Mostly make sure that binding is running.

[vital aspen]

Yes, all 0's

[pure relic]

@maiden wadi thanks for that link, its a good read. bookmarked for future use so I can understand it when more lightbulbs turn on down this programming journey haha

[tall umbra]

any recommendations for a mesh boolean (in run time) plugin?

[maiden wadi]

Odd. In your pickup, does this change if you add more than 1?

[vital aspen]

Yes. This is what the default settings for each item

[maiden wadi]

How are you sending the struct to the widget?

[vital aspen]

sending what structure to what widget.

let me start fresh,

I use a line trace to add the item into the inventory when I Press E. That's what this does

[maiden wadi]

But your Widget has a struct in it that gets sent to it. How does it get that?

Cause this is sending a struct to your InventoryComponent. So how does the widget get it after this?

[vital aspen]

Item, Item is the structure that is used for the item.

I like the effect of Draw Debug Box, so what would be a solution for final game build ? Would I construct a custom mesh? Use a Box Collision that is visible ?

[maiden wadi]

Niagara particle with ribbons.

[vital aspen]

Ok, It uses a interface.

[versed sun]

Ok, I'll look into that

[vital aspen]

I use the Item variable and it's set as a slot structure

It could be the binding. Now getting the Item info of Qty. I don't know.

[serene robin]

Appreciate you. I'm afraid I'm just too green at this. I've created my axis mappings and am in the blueprint with both InputAxis nodes, but not able to figure out float. Again, if you have time.

[vital aspen]

@maiden wadi Ok, ping mw when you think you have an idea

[maiden wadi]

Stepped out for a bit. Not sure I can help much until I know how you're feeding the items to your widget from the inventory after adding for display.

[vital aspen]

I showed it to you 2 times. I don't know what your wanting to see

[maiden wadi]

No, you're showing me how you add the struct to the InventoryComponent, and how your widget uses a different struct to display. Nothing there shows me how you spawn the inventory slot widget, and pass the struct from the inventory to that slot widget.

[velvet dagger]

How can I insert an image into an image object variable?

[maiden wadi]

Image Object being the Image widget in a userwidget?

[velvet dagger]

I think so :)

[maiden wadi]

Drag off of your Image widget and search for Set Brush, there are a few different options. You're probably looking for SetBrushFromTexture.

[vital aspen]

well I don't spawn anything. I just add the item right to the viewport and as for the other part. I need more detail on just your wanting to see.

[maiden wadi]

Lets start from there, what are you doing when you add it to viewport?

Just CreateWidget then AddToViewport? Is there anything passed into the CreateWidget, or?

[vital aspen]

drag and drop

I drag the class actor from the folder to the view port

[trim matrix]

every time I put a "delay" node behind a function it doesn't work. is there any way to work around this or put a delay before the round starts?

[vital aspen]

@maiden wadi Like this

[maiden wadi]

No, this thing. Where you're displaying the value.

How is the struct being passed to this?

[vital aspen]

in the inventoryslotpanel widget

[velvet dagger]

Never helped someone but I'mma try, can you send a screenshot of your nodes?

[vital aspen]

I open it like this

[trim matrix]

this throws my ball to a random side

I try to put the delay node after the beginplay and before the function but it doesn't launch the ball at all

[maiden wadi]

Looks normal. Show me the widget's RenderInventory?

[vital aspen]

I don't know if you can see this I'll try

[velvet dagger]

So it works without the delay node?

[trim matrix]

yes

but I want it to be delayed so when the round begins the players can get ready

but every time I put the node it doesn't work

[maiden wadi]

Quantity isn't being used here. You've never set that text.

[trim matrix]

I looked on the forums about this and it was confusing

people be saying that the delay function no worky before functions

[vital aspen]

@maiden wadi Right, All this does is setup the slots on the inventory widget.

[velvet dagger]

Try making a sequence off of the begin play node and have a delay node come off that and activate the set velocity node

[velvet dagger]

I'm not sure if it'll work but it's worth a try

[trim matrix]

ok

[vital aspen]

This show that it adds the number of slots to the widget

[trim matrix]

I tried with a sequence node before though. I plugged it in the second slot but it still didn't work.

it still doesn't work

[vital aspen]

How ever I do see that it setups the Icon to be displayed.

Hold on I think I just fixed it

[maiden wadi]

Correct. And you're spawning a slot here for each item in the inventory. You're setting the inventory's name, then the slot's icon, then adding it to the grid.

For starts your InventoryName SetText can be moved to before the loop, it doesn't need to be set in each loop iteration.

You're setting the icon. But you're not actually passing your struct to the slot widget. So it's defaulting to zero text in your binding.

[velvet dagger]

I'll try a few things out and give you a solution if there is one, but right now UE4 crashed so gimme a sec x d

Wait wait it's working again

[trim matrix]

lol

thank you so much

I have been stuck for like a couple hours yesterday

I tried looking up many things but it was to no avail

[vital aspen]

Ok, well that didn't work, and the inventory slots widget won'y load and I get all kinds of errors. Make no sense

[velvet dagger]

For some reason the sequence way works for me

[trim matrix]

did you copy my layout?

can you send a pic please

[maiden wadi]

All you need to do I believe.

[velvet dagger]

hol d u p no gimme another sec

[vital aspen]

Can you see what I added in

[trim matrix]

alrighty

[vital aspen]

when I add to the inventory. It stops me from opening my inventory. and I a few errors

[maiden wadi]

If you're going to set text here, make sure to remove that binding. Setting text explicitly will stop bindings from working anyhow.

What errors are you getting though?
