blueprint

[radiant bear]

it's a sequence

[static charm]

ah okay

was hoping it could split

[radiant bear]

this will give a sequence

based on the logic, which is set in another bp(only animation)

@static charm i can share my screen if it helps

[static charm]

nah it's good, i was just trying to think of how you can get somethign useful from the return

see if you can convert it to a string or get class or get anything from it

[radiant bear]

yep see what i can do let me what the node does first in cpp!

i think it returns a sequence but it's stuck on previous anim pose

also this node is from Animation locomotion library

[static charm]

not sure what you mean, timers/timelines don't work inside functions.

[radiant bear]

FSequenceEvaluatorReference UAnimDistanceMatchingLibrary::DistanceMatchToTarget(const FSequenceEvaluatorReference& SequenceEvaluator,
    float DistanceToTarget, FName DistanceCurveName)
{
    SequenceEvaluator.CallAnimNodeFunction<FAnimNode_SequenceEvaluator>(
        TEXT("DistanceMatchToTarget"),
        [DistanceToTarget, DistanceCurveName](FAnimNode_SequenceEvaluator& InSequenceEvaluator)
        {
            if (const UAnimSequenceBase* AnimSequence = Cast<UAnimSequence>(InSequenceEvaluator.GetSequence()))
            {
                const USkeleton::AnimCurveUID CurveUID = UE::Anim::DistanceMatchingUtility::GetCurveUID(AnimSequence, DistanceCurveName);
                if (AnimSequence->HasCurveData(CurveUID))
                {
                    // By convention, distance curves store the distance to a target as a negative value.
                    const float NewTime = UE::Anim::DistanceMatchingUtility::GetAnimPositionFromDistance(AnimSequence, -DistanceToTarget, CurveUID);
                    if (!InSequenceEvaluator.SetExplicitTime(NewTime))
                    {
                        UE_LOG(LogAnimDistanceMatchingLibrary, Warning, TEXT("Could not set explicit time on sequence evaluator, value is not dynamic. Set it as Always Dynamic."));
                    }
                }
                else
                {
                    UE_LOG(LogAnimDistanceMatchingLibrary, Warning, TEXT("DistanceMatchToTarget called with invalid DistanceCurveName or animation (%s) is missing a distance curve."), *GetNameSafe(AnimSequence));
                }
            }
            else
            {
                UE_LOG(LogAnimDistanceMatchingLibrary, Warning, TEXT("Sequence evaluator does not have an anim sequence to play."));
            }
            
        });

    return SequenceEvaluator;
}

this confirms it returns a sequence i didn't see any UE logs from this fun

i also logged her it's triggered also just not sure what's causing the character be stuck in pose

[tribal gazelle]

How would I attach a spot light component to the character's mesh from inside an actor component? Is that possible?

[static charm]

I was about to tell you to ask in the animation chat but seems it's full of questions and no answer at the moment lol.

[radiant bear]

yea i've been stuck with this from yesterday

[dim gust]

made all of this with "no collision" so the raytrace should pass throu em and hit the world, still no luck, now it doesnt hit nothing 🥲

[radiant bear]

i have a curve compression setting

might that be the problem?

[dim gust]

i need the G as my bff

[static charm]

sorry bed time here, goodnight and good luck everyone.

[dim gust]

we're doomed Adore!

[radiant bear]

lol!

i guess i can put aside distance matching for now or do it manually through cpp

[dim gust]

wtv we do we are doomed!

[radiant bear]

can post you ray cast code?

i'm not good at BP but will try to help

[dim gust]

im working with BPs

[radiant bear]

i mean your bp

[dim gust]

yes the float number is ginourmous because i was trying to hit the world

and he is so far

they were hitting the "space capsule" before i turned off the collision

now they dont hit anything

[radiant bear]

can you tell me what your trying to achive?

[dim gust]

i wanna be able to click on a country and then go on to another level xD

just that xD

in a certain country, already made a child for it on the world mesh

[radiant bear]

so your getting location based on mouse cursor?

[dim gust]

thats right

we're doomed adore!

[radiant bear]

can you show me the logic for when you click?

[dim gust]

still havent one, and i dont need to, like, when the cursor goes through the world it should appear that its hitting it

i only need that logic after

[radiant bear]

i mean how are you starting to cast ray?

it's always casting and moving with cursor?

[dim gust]

@radiant bear

[frosty heron]

Add a custom event to spawn on the owner actor.
The component can just get the owner and run the event or interface

[dim gust]

yes at least it should be

[dawn gazelle]

As I said over an hour ago...#blueprint message
You just need to have a mouse click input, Get Hit Result Under Cursor, use whatever channel, filter out what you want and check what actor was hit.

[radiant bear]

alright so your ray is not hitting anythin that's the issue right?

[dim gust]

after i turned off collision for the spaceship it doesnt hit anything

right

if the collision is on for the spaceship it still hits the spaceship

[radiant bear]

this is also a valid approach

[radiant bear]

your would has collision enabled right?

[dim gust]

of course

[radiant bear]

the float why do set it manual can you try Casting an endless ray and end it when it hits something?

[dim gust]

is that even possible?

how do u cast an endless ray?

[radiant bear]

its you idk how on bp give me a sec i'll se if that's valid

[radiant bear]

i mean you have Starting and ending point right?

[dim gust]

my starting point is where the camera is at

[stone pelican]

Is there anything I can add to see if the character is moving? right now holding sprint will drain stamina even if my character isn't moving

[dim gust]

actually i dont have a ending point now that i think about it

[radiant bear]

you can check the character movement variable

like acceleration

[radiant bear]

alright give me one moment

[frosty wadi]

so i have to increase r.Shadow.Virtual.MaxPhysicalPages to get things to work properly but when i increase it to a cetian point or higher thne whne i try to launch the game after packaging it or whatever it csays it crashes

[frosty heron]

Told you yesterday. Get the cmc and get the velocity then maybe get the length. See default third person project and open the anim bp where they set the speed

[radiant bear]

bool PerformLineTrace(AActor* ActorToIgnore, FVector Start, FVector End, FHitResult& HitResult)
{
    FCollisionQueryParams CollisionParams;
    CollisionParams.AddIgnoredActor(ActorToIgnore); // Ignore the actor that initiates the trace

    // Perform the line trace
    bool bHit = GetWorld()->LineTraceSingleByChannel(
        HitResult,    // Output Hit Result
        Start,        // Start location
        End,          // End location
        ECC_Visibility, // Trace channel (you can define your custom channels)
        CollisionParams
    );

    return bHit;
}

this how you would do it let me see if i can give you a bp version or you can make a cpp file use this function expose it to bp and use it there

[dim gust]

omg C++? D:

would love to learn

just know a little of C# and GDScript

[lunar sleet]

#cpp has some good resources pinned and a very knowledgeable crew

[frosty heron]

You can use that function in bp

Lin's trace by channel

[radiant bear]

you can copy pase this

in your cpp

it's valid

[dim gust]

how so? I can paste that in my BP? o.o

[radiant bear]

i think he know the function in bp

[radiant bear]

one sec

[dim gust]

i have Visual Studio if it helps... x'D

[dawn gazelle]

You do have an end point for the trace which is your camera forward vector (so whatever direction the camera is facing) * that really large float (so it'll be a point somewhere that far away in the direction of the camera) + the camera location (so it's in line with where the camera is)

[radiant bear]

yea you need that

[lunar sleet]

what are we doing here, reinventing line trace? 🙂

[radiant bear]

or any ide

[dim gust]

basically xD

[radiant bear]

me?

[frosty heron]

Why? What do you need?

[dim gust]

ok ill make a new video showing whats goin on

[frosty heron]

Endless trace? Just shoot a projectile with box collision and give it a long life time

Nothing should be endless imo

[lunar sleet]

what could go wrong 🙃

[frosty heron]

Asking for infinite is asking too much

[radiant bear]

so you know how to make a cpp class in unreal?

[radiant bear]

yea but he can stop it when it hit something

[frosty heron]

U still need beginning and end so what exactly the strategy here

[dim gust]

here it is the problem

u can see that when i put my "spaceship" with collision

the ray detects it

when i put it off

it doesnt detect the world

i want it to detect the world!

xD

[dim gust]

never did one, but with a little of research ill be able to do it for sure

[frosty heron]

So Ur issue is u want to do linetrace that doesn't stop at first object it hir?

Then use multilinetrace node

[lunar sleet]

that make literal float is...interesting

[dim gust]

i want it to ignore the objects but that doesnt ignore the world

[frosty heron]

Then use custom channel for the hit test

[dim gust]

its a ginourmous number because the world is really far away from the spaceship

[radiant bear]

i can help you with that wanna vc?

[lunar sleet]

you can't just make a float and change its default value to that?

[dim gust]

u can help me? Really? D:

[radiant bear]

i think the line isn't hitting anything

[dawn gazelle]

"No Collision" doesn't do what you think it does.

[radiant bear]

yea make a custom node with the fun i mentioned above

i'm not fluent in bp

[lunar sleet]

away with you demon 🙂

[radiant bear]

but this for the space ship which he don't want to detect so it shouldn't be a problem

[frosty heron]

Add custom collision channel

[dawn gazelle]

He is tracing for objects, namely "WorldStatic". WorldStatic is blocked by "No Collision"

[dim gust]

so what ur saying

is that he is detecting the spaceship

anyway

[frosty heron]

What u gonna do in cpp anyway? What's the actual start

[dim gust]

even if i set it to no collision

[dawn gazelle]

Yes. Because it's blocking the trace.

[dim gust]

i see

[radiant bear]

just creating a raycast fun and expose it to bp

[dim gust]

and wt hell is cpp? I thought unreal worked with BPs and C++

[radiant bear]

but this could be the reason too

[dawn gazelle]

C++ = cpp

[lunar sleet]

ah, No Collision is just a default preset rather than actual no collision?

[dim gust]

ow

[frosty heron]

I mean your custom raycast function

What's the content to fix his problem

[radiant bear]

what i intended?

[lunar sleet]

oh right, it's the wrong field

[radiant bear]

it's casting an endless ray if hit something he get the some info and then you can do what he need to do

[dim gust]

Adore pfp from a distance looks like Newt Scammander from Fantastic Beasts

love it

[radiant bear]

it's just a bool you get an idea

[frosty heron]

How are u gonna cast endless ray? If I may ask

[dim gust]

wow.... i wanna be a nerd like u guys, truly

i wanna get into the conversation

and give my ideas

[radiant bear]

i assume giving it a starting location and direction without a range should do

[dim gust]

for now i just know that i must ignore the spaceship totally

[frosty heron]

Wait wdym

[dawn gazelle]

"Get Hit Result Under Mouse Cursor" == "endless" trace.

[dim gust]

he wants to start in a location outside the spaceship if im not mistaken

[frosty heron]

Oh u can do that?

[dawn gazelle]

Just need to set collisions up correctly.

[frosty heron]

I mean the endless trace

[radiant bear]

your one needing help right?

[dim gust]

yes lol

but u also needed if i recall

[dawn gazelle]

It basically just tries to get whatever actor is under the mouse cursor but works with collision profiles.

[frosty heron]

Then maybe should just do this, that's exposed to bp

#blueprint message

Actually don't want to butt in, gl

[radiant bear]

GetWorld()->LineTraceSingleByChannel

[radiant bear]

for Casting

he can call the bool fun i mentioned above where we wants to cast or just on updated

for testing

[dim gust]

so

u want me to replace this

ok guys nvm ive taken 2 much of ur time, i will do it one way or the other grrrrr

xD

Thanks ❤️

[frosty heron]

Look at how to set up collision channels

And when u trace just give it a long number

I haven't seen anything that define endless trace yet, maybe under cursor just have a maximum range?

Don't know how you can give direction and location but no magnitude

[dim gust]

well the camera is static if that helps

[radiant bear]

in bp you need a endpoint defined

[radiant bear]

just few mins man i'll see if you can do it in bp or i'll make a custom fun for you

[dim gust]

thanks man, if u want i can cast my screen for u

that would be life saving ngl

[dim gust]

ill try that o.o

@radiant bear look at Datura go D:

[frosty heron]

The cpp function also ask for end vector tho

@dawn gazelle how does the get under mouse cursor trace work?

I don't have editor on me rn

[dim gust]

wait wait, let me try Datura method and ill come back atcha

[dawn gazelle]

Just need to make sure whatever trace channel you have defined on the get hit result isn't being blocked by anything in the foreground before it, and that the thing you want to check overlaps or blocks it on that channel.

[radiant bear]

yea but i think we can skip that value, let me set something up quick

[dim gust]

maybe im just that noob

https://tenor.com/view/panicking-gif-22262539

[dawn gazelle]

Right click on the "Hit Result" pin and select "Split Struct Pin"

[dim gust]

WORKED

ur a genious!

let me continue with ur bp

aham

i cri eweritiem

i think that everything is how its supposed to @dawn gazelle

[dawn gazelle]

Not seeing any mouse cursor on the screen... You need to press your interact input to show it?
You are using the right click input node but you have the print string saying "Left Pressed" Make sure you're actually clicking right click and you should see something printing on screen if this pawn is controlled.

[dim gust]

ur not seeing the mouse because of my obs settings

OWWWW

IT WORKS WITH THE RIGHT CLICK

i mean it just says hit actor xD

not sure if im hitting the world

[dawn gazelle]

Ok, now you may need to verify that the actor you want to hit responds to the Camera channel.

(Should have Camera blocked)

[dim gust]

i was hitting basically everything xD

[lunar mulch]

I'm enabling and disabling camera lag to smoothen out the crouching camera transition. However whenever the camera lag is disabled inside the bp it will cause a slight jitter to the camera in-game. Is there a way to reduce this somehow? I've spend hours trying to make the camera transition smooth. Scratching my head at this point.

[dawn gazelle]

You got a response from Hologram2. Again, you need to verify the collision settings on the thing you actually want to register. So if that's your planet or some other actor on the planet or what have you, look at its collision settings.

[dawn gazelle]

Not sure if "Default" responds to Camera trace channel.

[dim gust]

let me check the hologram one

weird? o.o

it responded to the hologram

however

its set to block all dynamic

weird?

xD

[dawn gazelle]

That's different than Default.... Try putting your planet to Block All Dynamic and see what happens.

[dim gust]

yup

well at this point, we might get a rope

and a chair

https://tenor.com/view/tissue-roll-hangging-suicide-funny-gif-22276377

[frosty heron]

Or make a custom trace channel

And have the world block it

[dim gust]

guess ill have to look into it

its just weird that @dawn gazelle method didnt work

really

[frosty heron]

It work wtf

[dim gust]

not for the planet

[frosty heron]

Cuz u got meshes that block the cam channel

[dim gust]

do i?

[frosty heron]

He told you to ensure that your meshes don't block it

[dim gust]

Theres no glass there

in the window

its open space

[frosty heron]

It detects hologram

[dim gust]

yes it does

[frosty heron]

So the hologram blocks the world

Because it blocks cam channel

[dim gust]

how the.... its not even in front of the world

its not even big enough for that

and it just responds when i click on it

in the hologram literally

besides

both hologram 1

and hologram 2

respond

[frosty heron]

Select Ur hologram in the world outliner

Then set the view mode to wireframe

The plane must be bigger than what Ur naked eyes van see

[dim gust]

ok u want me to put the hologram near the world right?

and set everything to wireframe

[frosty heron]

I will just add a custom channel for special need object

And I can forget about all the hologram or w.e u place in the world

[dim gust]

Cold Summer, i would do that, i would de really happy to do it if it would help, but im a newb, i needed instructions

is there a tutorial or wtv?

[frosty heron]

Youtubeable yeah

[dim gust]

can it be a "new object channel"?

and i put there the Earth

[dawn gazelle]

Sure

[frosty heron]

Or planets 🐱

[dim gust]

im seeing a lot of tutorials but they dont use BPs hmmm

how would the BP be in this case?

[frosty heron]

Wdym? They all should be in bp

In thr project setting

[dim gust]

https://www.youtube.com/watch?v=QQvHZLB4CTU&ab_channel=MattTaylor

[frosty heron]

I opened enough videos today

[dim gust]

xD

yeah maybe i should sleep over this x.x

been on this for 2 long and tried lots of stuff

[frosty heron]

I opened it anyway because u said it's not in bp

[dim gust]

my almost 31 year old head cant handle it

[frosty heron]

But it's in bp so I dunnoe wat u mean

[dim gust]

u have a funny personality xD

[frosty heron]

I'm 32

[dim gust]

i opened enough videos today

welp i opened it anyway

xD

[frosty heron]

Yea cuz I sense bs

And I was validated

[dim gust]

wdym? Theres no bps for the collision

he just messes with the collision in the details

[frosty heron]

U create the new channel in project setting

[dim gust]

yeah i did

[frosty heron]

Then u set the channel correctly for your world

Then all that's left in the bp is to do what datura says

[frosty heron]

But change the channel from camera to earth

[dim gust]

OOOOOOO

NOW IT MAKES SENSE

THANK YOU

u.u

in the earth i put block

and the other ones i should set to ignore?

or overlap

[frosty heron]

Depend on your game

But if u just want the earth or planets

[dim gust]

i just wanna click in Portugal which is my country, then a second level comes

[frosty heron]

Then don't make it block for others

[dim gust]

i already have a child in portugal

i mean a child from the planet

xD

[frosty heron]

Click on random actor in your level and see if the earth is set to ignore

[dim gust]

its set to block

[frosty heron]

Then you have a problem

When you create the custom channel, set the default value to ignore

[dim gust]

okok

like sio

so

[frosty heron]

Try to see what collision look like on static mesh placed in the level

If it's still set to blocked then I dunnoe maybe start over

[dim gust]

they r set to ignore

[dense jacinth]

So I have two "levels"
One is just a main menu "level" that spawns in with a UI and some buttons

I have one of the buttons connected like this
https://i.gyazo.com/c66a5a186932d076a402c26a59c98e76.png

However, when I load that level, I don't get anything. What I'm assuming is happening is my character isn't actually spawning

when I try to play the level in the editor it works fine

Do I need to manually initialize the level by spawning in the character myself? or am I using the wrong node

[dawn gazelle]

You probably want to do "Open Level".

[dense jacinth]

I just changed the node and it works just fine
Thank you, I was assuming I was just doing something very simple wrong

Is this load level instance for if you need multiple instances of the same level for some reason? Assuming some sorta multiplayer thing?

[dawn gazelle]

Level streaming / World Composition.... Basically allowing you to expand the world as needed.

[dense jacinth]

ah.. to save on memory I'm assuming? for very large maps

Well, I'm just doing 2d stuff right now so it's probably fine for me to stuff each level into it's own "level"

I'll learn about level streaming when I get around to needing it

hm... actually just noticing a strange issue now that I reloaded the level

I'm unsure if this actually counts as a blueprint related question but I'll continue here for continuity

so I have two actors that are basically just a collision box, and a "paper tile map component", I got it from dragging a tile map into the viewport

For example, this

https://i.gyazo.com/4368002f7c7f871c0fea231dcbff1441.png

however, when I reload the level, the actor sprite disappears and the... (box?) gets strangely enlarged, although it appears to be only visual

https://i.gyazo.com/00741698990579281c90adfd3c2da14b.jpg

on the right there's a normal looking heart, I just dragged that one onto the map and it's just fine

even when I play the level the two actors aren't visible, although one of them is a launch pad and it still works just fine, so the collision box is still there. Also the launchpad collision still appears to be in the proper place and size, which is why I think the box enlargement is only a visual error, or else the collision area would be too large

anyone have any idea what's causing this issue?

If I reload the level again the new heart ends up disappearing as well

Checking the actors themselves, they're not set to "not visible", and changing that setting doesn't make them reappear

[dim gust]

@dawn gazelle how do you call a blueprint to a cpp?

I already tried so many things to my bp. I’m thinking that maybe with cpp I can do the raycast properly

[crisp urchin]

you cant

[dim gust]

Ur wrong

[crisp urchin]

you cannot call the actual bp nodes

just the c++ than it inherits

[dim gust]

No. I meant. Doing a certain part on a bp and another one in cpp

It’s doable

[crisp urchin]

your wording is confusing

[dim gust]

Im Portuguese 😌

[novel rock]

This works but is it the right way?

[dim gust]

It works?

[novel rock]

yes

[dim gust]

Then it’s the right way

[novel rock]

Time to give myself some well deserved pats on my back.
Good job me for properly programming with blueprints. 😉

[true igloo]

Why does unreal allow a Bp reference to have multiple in connections. This caused a crash for me, and I can’t think of a reason to allow it as it seems dangerous, so why have it happen at all? Is the idea that you can have ifs and hope that only one is always sending?

[solemn basin]

I'm making a card game and using a widget for the hand. I can get the front of the card, but how would I get the back of the card?

[frosty heron]

That's disgusting tbh

[frosty heron]

Cpp not gonna save you for this simple problem

And FYI u do it the same way cpp or bp

[dim gust]

I found something actually

[frosty heron]

U are using line trace by channel

Ur job is to ensure that the channel are set right

[dim gust]

If I move the earth really close to the spaceship it can detect the earth

But it has to be really close

[frosty heron]

That's not solution

[dim gust]

I just said I found something

[frosty heron]

Maybe under cursor has range I dunnoe, nothing that I know allow for infinite distance cast

Don't have pc on me to check the implementation

[dim gust]

Dw I will check it out tomorrow. It’s 5:40 here xD

[frosty heron]

U can do line trace by channel again. Change the channel to earth and make sure that the range is at maximum number unreal allow you to write

[frosty heron]

Pretty sure u can do that. Ask in cpp I'm sure they know the right answer

[crisp urchin]

(?

[dim gust]

Told ya von Carlo

[crisp urchin]

You cant. He is confused/ didn’t understood my statement. Also you meant something entirely different

[gentle urchin]

It does

Have fixed range*

[gentle urchin]

C++ does not know of things made in bp. If you want to call a bp function in c++ it must be decleared in c++ (BlueprintNativeEvent or BlueprintImplementableEvent)

[gentle urchin]

Why is there a sequence + flipflop + 2 set active nodes

Ah 2 cams.

Third + first, gotcha

You could solve this with 1 bool and two set active nodes.

[red berry]

Why are some of my blueprint size maps 200mb? Is this too much and should I somehow try to lower it? I heard about people using soft references, but I've never found why and how to use them

[gentle urchin]

Its to avoid just that

[frosty heron]

https://m.youtube.com/watch?v=K0ENnLV19Cw&pp=ygUaRGVtaXN0Znlpbmcgc29mdCByZWZlcmVuY2U%3D

[gentle urchin]

All assets that are hard referenced are loaded along with that class

Including other classes (by casting or storing har references to them)

[frosty heron]

It's safe to cast to a cpp class in bp land right?

[gentle urchin]

Soft references are loaded on demand with Load Asset Async

[gentle urchin]

Yeah native classes is safe 🙂

[frosty heron]

It will only get bigger if u don't start using soft ref in the right places

[golden gull]

Guys I have a theoretical question, if you were to make different types for doors like a sliding door, rotating door, locked door and etc. would you make a base blueprint and then inherit each new type of door off of it and add the new logic or would you just make one big component and add variables to control which type of door it is ?

[frosty heron]

Make a base door and inherit from it for diff types of door

Base door should handle common logic like loced

[gentle urchin]

Door logic + transform lerps

Sliding door is a lerp of location

While hinged door is a lerp of rotation

So if you make a lerp based on transform, you have your base door bp

Wrap the lerp logic in a function and you can modify it on child bps if needed (double sliding door f.ex )

[spark steppe]

does GetAllActorsOfClass just look at one big array or is the data more like a class tree?

[keen hedge]

The former. Look at TActorIterator/TActorIteratorBase in C++ if you want to see how it works exactly

[red berry]

Are your blueprints 200mb? Two of my actor components are 200mb in the size map, I dont know if thats bad

[frosty heron]

I never check but loading my player in my old project loads the entire game. My loading time is like 1 minute or more.

I don't know if 200mb is bad or not but in my opinion most game should use soft ref. Unless it's a really small game or just a prototype

[red berry]

Whats the point in a soft ref if its going to always be loaded in the game? I have "Item3D" as a blueprint which represents 3d item props in the world. This is a base class that every item uses. Why would I need a soft reference to this?

[tame pecan]

You don't

[frosty heron]

U use soft ref for things that is not gonna be loaded right away to the game

Think about icons in your inventory

Sounds in specific levels

If u can change between skeletal mesh for your character that can also be soft ref

Imagine you hard ref everything in your data table

That will load the entire thing once u run the game

[tame pecan]

he's talking about a base class that should have like a size of a few kb

no need to soft ref that

[frosty heron]

I have no idea about those maps. He asked about soft ref 3 hours ago

If it's something that gonna be loaded like your player character then don't bother with soft ref

[tame pecan]

that was their question

[red berry]

I might as well ask about both since they're both confusing.
My Item blueprint is 223mb, 220mb of that is the player blueprint. Why is this not only 3mb?

[frosty heron]

If u have hard reference to your item bp in your character bp

Then you will load the entire item bp

Downside of blueprint

[tame pecan]

your base class shouldn't be more than a few kb. It should just contain logic essentially

and let the children do the asset referencing

[keen hedge]

Or if you just cast to a specific bp class

The bigger problem is that your player bp is 220mb 🙂

It's probably okay if your item references the player ,as I assume you want to load the player right away anyway. Now why is player referencing 220mb of assets, thats another story

[red berry]

So there's nothing I can do about that?

Also my "Item description" class has a "StorageImage" variable which is a MaterialInterface, hard reference. Should this be a soft reference since its the icon of an item and it won't always be loaded? How would the game know what icon to load?

This async loading stuff is confusing for unreal engine. In javascript web development, its more easier to understand because of "skeleton UI" and loading spinners, which show by default, then once loaded, the asset replaces that.

[keen hedge]

In UE you get 'skeletons' too for materials in the form of gray default grid material until the real one is loaded 😄

[frosty heron]

If your item reference an icon and your player reference the item. The icon will be loaded regardless u need it to show up or not

Use soft ref on your icons, texture, skeletal mesh

Load them as necessary

[red berry]

My player BP is ~200mb because its referencing Manny and Quinn. I don't think theres a way to reduce this?

[frosty heron]

There is

Soft ref away 🙂

[keen hedge]

You can soft reference manny/quinn and either async load or make a loading screen where you would preload your immediately required assets

[tame pecan]

This is such a micro optimization. If it's the player character's materials that'll always be present (unless they have some customization)

no need for soft refs

[red berry]

I didn't do anything special to the blueprint. It was like that from the thirdpersontemplate

[tame pecan]

dont worry about it, it's the player character

[frosty heron]

Agree and that's what I said earlier. If it always gonna be the player character then no need for soft ref

[keen hedge]

It is unless they want to have different player skeletal meshes down the line

[tame pecan]

read my whole message please

[frosty heron]

It really depend on the scenario for example my player character have 20 skeletons to chose from. Which in this case I would totally need soft ref

I didn't say he has to do it but he asked how to not load

Soft ref is the way but Wether u should is different question

[red berry]

So soft references are only for graphics stuff, like meshes, textures, sounds? Its not for logic, like blueprints, actor components, structs, enums, etc.?

[frosty heron]

U can async load class but don't know if u have to

[keen hedge]

You can soft reference entire blueprint classes as well

[frosty heron]

Most of the heavy stuff is like textures sound and material

[red berry]

Yeah thats what I'm thinking, just the heavy stuff that takes up lots of MB/GB I will soft ref. The logic I'm not going to bother with, like the logic for inventory or for handling pickups. They should work, even if the player can't see the actual item (or if the item is just a LOD or placeholder)

[keen hedge]

You don't need to worry about code/logic size when it comes to loading unless you're worried about cache locality etc but you shouldn't worry yourself with that stuff off the bat

[frosty heron]

I assumed you used data table for your inventory? In which case u should totally soft ref the icons or material

Imagine loading 200 icons when u don't have to

[gentle urchin]

Or 200 meshes

With materials and all

Even in your manny quinn example

Do you really need them both loaded, always?

[red berry]

How do you make the default player class soft reference the mesh? I don't see an option
No idea the difference between 01 and 02, are they male or female or lods?

[keen hedge]

Next to the variable type, the little colored ellipse, click it

Actually just checked, depends on where it is

[red berry]

I know that, but there's no option for the Character. I created a new empty third person template project, and the BP_ThirdPerson size map is 200mb

[keen hedge]

Oh if you want to change the skeletal mesh, you don't put it as a default

Instead you put it in a variable (of a soft ref type) and you can then async load it in your event graph and set it on your Mesh component at runtime

That way your class wont have a hard reference to it and you'll see the size diff

But like I said before, unless you're customizing the character (character creator or different meshes per character) you probably dont need to do this

Because it adds complexity and now you likely need a loading screen etc etc

This is instead useful for things you don't need ALL the time. Like UI icons etc etc

[red berry]

Yeah I'll worry about that later, I was just trying to get the whole soft reference thing to work, that way my other blueprints won't be 200+ mb just because they reference the player

[keen hedge]

Do note that the blueprints themselves are not "200mb", the skeletal mesh and all its assets are. That means that once that is loaded once, it's not loaded again for each individual thing referencing it

[frosty heron]

Sent you video earlier by epic on how to do async load.
They actually did the skeletal mesh of the character. So if you need some exercise to get rid off many and Quinn from the map then the video should tell you all you need

[red berry]

Yeah I'm 1 hour in and I still struggle to get it, so I'll have to rewatch. I do understand that they have a default skin, and while the game is running, after the second skin is async loaded, the character changes to the second skin. But I don't know how to implement it myself.

I tried to play around with removing the reference to the quinn mesh in a new third person template project, and it works. The sizemap is only 7mb now. But the player mesh has disappeared. I have a soft ref to a mesh, which is exposed on spawn, but there's no option to set it in the menu, since there's no player blueprint in the game world. Its spawned by a player spawner.
I guess there's no way to set starting variables for the player?

[frosty heron]

It's only 3 nodes isn't it

Soft ref = address

Think of it as path to the object

U use async load to resolve the path to a hard ref

[red berry]

I kinda made it work on a new third person template project. I can spawn another third person character, with the default mesh as quinn, but the blueprint is still 7mb.
Idk how to make it work for the player that gets spawned by the player spawner

[frosty heron]

On begin play, get the soft ref, async load , on completed cast to skeletal mesh.

Get mesh-> set skeletal mesh from the cast return value

So naturally Ur mesh should be empty at the start

If u already have Quinn there then it's loaded already

[red berry]

Not working in begin play?

[frosty heron]

From object to the new mesh

Is the new mesh the Quinn skeletal mesh?

From object cast to skeletal mesh

Then plug it to the new mesh

[red berry]

Do I gotta cast it?
New mesh is Skeletal Mesh

[frosty heron]

Yeah cast

[red berry]

Still invisible, and thats just for the ThirdPersons I manually place in the world

[frosty heron]

Print string to make sure it runs

[red berry]

Yeah i put it at the end and it prints, but no show. This is in beginPlay

[frosty heron]

Can you print string the skeletal mesh?

See what it says

[red berry]

This doesn't print, so I assume the cast has failed.
If I print the skeletal mesh its an empty string, so nothing

[frosty heron]

Yup

What is the type of your soft ref?

[keen hedge]

What is New Mesh, what type?

[red berry]

Skeletal Mesh (soft object reference)

[keen hedge]

And did you maybe forget to set its value to manny/quinn (for example the default value in Details pane)

Then just print the Object to see what it is

[red berry]

For another instance of ThirdPerson (not the player character that gets spawned), I set these details.
"Mesh" is set to none, and "New mesh" is set to Quinn

[frosty heron]

Can you print string the object

[red berry]

If I set the "mesh" directly (and not "new mesh"), the mesh appears, but that makes the whole soft ref async loading pointless
Which object?

[frosty heron]

From async load asset

It has object as the output. Print string that

[keen hedge]

Btw where did you put this code, is it begin play or what?

[red berry]

It gives nothing.
I put it in beginplay

[keen hedge]

Can you just set a bp breakpoint on the cast to see if it ever actually finishes loading

[wooden wagon]

everytime i visit this channel i see your messages xd

[red berry]

Yeah I forgot to mention it fails to cast

[frosty heron]

Holiday is boring. I wish I am near my computer to do my game

[wooden wagon]

before i want to start developing my game i want to learn every aspect of the engine (learning for 1 year now)

[frosty heron]

Show how you print string the object

Imma shower, might take a look later

[frosty heron]

The learning will never end, just make a small game first

[keen hedge]

Gonna take a decade to learn EVERY aspect 😄

[keen hedge]

Can you show us how you defined the variable? Sc that and the details pane pls

[red berry]

I print string the object instead of Skeletal mesh (output) and its still "" (empty)

[frosty heron]

Print screen

U gotta do it after completed

[frosty heron]

New mesh is empty

[crude spruce]

I do melee traces on weapon actors.
the system is extensive when it comes what needs to be communicated.
Im current interfacing the weapon to a component on the target. And plan on working this into a sort of hub for resolves.

But does anyone have a recommendation beyond** weaponactor > target interface > actor component**?

[keen hedge]

I did everything exactly the same and it works

[frosty heron]

His new mesh is empty

So for his player character that get spawned it will fail

[keen hedge]

It's not, he set it on the instance

[red berry]

wtf now it works. But I had to move the async code around

But "PlayerStart" doesn't allow me to set "New Mesh", so the player's version of BP_ThirdPerson is still invisible

[keen hedge]

You can just set the default value in the BP class

Instead of dragging it into the level and setting on the instance

[red berry]

Yeah that works for the player and the other instances load whatever is preset there. And the sizemap is only 7.1MB which is a lot better than 200MB.
Thanks for the help everyone!

[keen hedge]

Do note that your character now might be invisible for a couple of moments while its mesh is being loaded

[red berry]

Is that where loading screens come in?
What about for icons? Should there be some placeholder loading icon, then once its loaded, the icons appear properly? Kind of like how websites do it?

Also if you were playing an open world game, and you walk near an enemy area, wouldn't the enemies pop in and look glitchy for a few frames until they're loaded properly? Should you async load when the player is far away?

[keen hedge]

Depending on your game, yes. Modern games do it by having your character crawl through a crawlspace or climb a long ladder while stuff is being loaded lol

What about for icons? Should there be some placeholder loading icon, then once its loaded, the icons appear properly? Kind of like how websites do it?
Icons typically load very fast

Also if you were playing an open world game, and you walk near an enemy area, wouldn't the enemies pop in and look glitchy for a few frames until they're loaded properly? Should you async load when the player is far away?

That is a whole other can of worms involving level streaming / world partition etc etc. Usually you would stream in adjacent "blocks" of the huge level etc

[thin panther]

You would also typically roll your own significance manager or something that will handle updates of things, and loading necessary references a bit out of view

[young meteor]

How can I update material parameters from code in my widget?

In this example I'm trying to have some borders around a skill icon in a skill tree change based on unlocks.

[frosty heron]

Set texture parametre value

[frosty heron]

Get your material instance dynamic -> set texture parametre value

U will need to use dynamic material

To change something at run time

Create dynamic material instance, pick your material. Add it to the widget.

Then promote that material instance as variable.

From there you can set the texture parametre value

[young meteor]

I'm not even sure if I'm formulating this quite right.

I have a skill tree widget. In which I'm using a "skill node" widget I have made.
In this "skill node" widget I have set an image to use my material.

Not sure if this changes anything.

[frosty heron]

Read what I suggested above

[young meteor]

reading

[frosty heron]

You can change anything from the material. Texture scalar or vector

Just set your parametre name accordingly and with the right type

[versed sun]

and Vector will be a Linear Color

[young meteor]

Still digesting. Don't worry. 😄

[versed sun]

And , FYI, you only need to Create and Set the Dynamic Mat once , after that you can just Set Parameters at will

[young meteor]

Think you already tried to tell me, but to set a color I do what?
It wants a float?

[versed sun]

Vector

[versed sun]

Set Vector Param

[young meteor]

ah

my bad

Need to do this for every skill node.

Guess I just collapse this into a function with the inputs to not bloat then code, and the loop through all nodes. Sounds good yeah?

[frosty heron]

Don't know how you setup your widget but there is a few time where you have to redo something over and over

Is your widget an individual button? Then that's a problem

Your skills node should be a base class widget on its own

With function that create and set the material

[young meteor]

It is its own widget yeah.

[frosty heron]

Then you can move this to the skill node widget to avoid doing it as many times as your skill node

[young meteor]

Good point.

Just create an public variable in there I can set from the "skill tree" side.

Thank you very much. Both of you. 🙏

[gentle urchin]

I prefer feeding the data into the sub widget

And let it handle itself

When skills are activated i suspect you can grab some identifier of which one got activated

[vital cargo]

Can someone assist me with this possibly? So I have a spline which I use, I need every 2nd mesh to rotate 180 degrees, which is does but now the location is off and I don't know how to fix it.

[versed sun]

Simplify down to this

[young meteor]

The sub widget is a button forwarding the "button clicked" event.

I'm thinking when a player click in skill tree, I cast to Game Instance to set it as unlocked.
And the sub widget itself will have a reference to Game Instance already, and update it's parameters based on logic.

Sounds right to you?

[vital cargo]

I'll give that a try, I only learnt about the Modulo function.

[vital cargo]

100% cleaner with that, thanks. I just need to figure out the issue with location now

[versed sun]

That would be with your Origin point in your mesh

[young meteor]

Sorry if I'm asking a stupid question here.
If I cast to Game Instance and make a reference because I want to use a value from it.
Is that like casting to it on every tick to check if it is a new value? (In other words bad performance)

Asking because it would be for every skill node.

I could get around it by casting and checking a value when a node is actually pressed. This just seems easy.

[versed sun]

Game instance can never change

[gentle urchin]

I wouldnt worry about casting to GI

[versed sun]

Save it once at the start and you are good

[gentle urchin]

Thr othet way around is another issue 😁

[young meteor]

I don't mean if GI change. I mean a value in it. Like Player Level in the screenshot

[dawn gazelle]

A value changing doesn't cause any additional execution of code unless the event that is changing the value causes additional code to be executed.

[gentle urchin]

Spoken like a true yoda

[young meteor]

So if the parameter is set based on Player Level like in the screenshot, it would not update itself if the Player Level in GI changes?

[dawn gazelle]

Correct, unless you had some sort of function that you use to update the Player Level to call additional code.

[versed sun]

if that is on tick, dont re-make your Dynamic Mat

[young meteor]

Got it. So I will update it when the skill node (button) is pressed then.

[dawn gazelle]

Or.... You can create a function to update the player level and have it call an event dispatcher in the game instance and call that function in every place that you update your Player Level variable. If other things need to know when that Player Level variable changes, they can bind to that event dispatcher in the game instance so they can do things based on when the value gets changed.

You also don't want to keep recreating your dynamic material instance. You should only need to do that once - you can promote it to a variable and modify when needed.

[young meteor]

Yeah, was a bit too quick there.
Same for GI reference. Can do those 2 on construct.

Thank you to all of you.

[gentle urchin]

Event dispatcher is the way to go

Then any class who cares can just subscribe to that, and get the new level whenever it changes 🙂

[young meteor]

But it complicates, because Player Level is just a quick example to show something here.

Really I need a map with structs (I think) to keep track of node unlocks.

And if I bind to an event all nodes need to listen to that event and update.

Still consider it a better solution?

[gentle urchin]

Dispatcher helps regardless

I just have an array of gameplaytags for unlocks

Well, a struct with tag + int

As some nodes are stackable

[young meteor]

You still don't prefer to just run the code on the node that was clicked like this? (still swapping Player Level for something else)

[tall field]

Is there any way to use the "OnNotifyEnd" node when playing a montage? I've tried making a notify named "OnNotifyEnd" but it doesn't seem to work

[gentle urchin]

Id run the node logic in the node, but allow it (or its parent) to register to a dispatcher for when a new skill is learned

Or a level gained etc

[versed sun]

Does that work like that ? the Setting Brush , THEN making the dynamic mat ?

[young meteor]

No. Working on that right now 😄

[versed sun]

ok, Make the Dynamic mat first , then set your brush to it

[young meteor]

Works better 😄

[young meteor]

Okay. Thank you. 🙂

Thank you Ryck0Shae. Saved me time for sure 🙂

[versed sun]

ooohooohoo....
When playing in New window, if you Ctrl-Z , it will undo changes you made in editor

[haughty egret]

So, can someone please explain to me how to get Enhanced Input to trigger only once for a key press?????

[haughty egret]

Thanks for replying, unfortunately I tried Started however it will activate even if a trigger condition is false.

So if I have a chorded action, how could I get a single trigger on press?

[versed sun]

sorry , no clue on chorded stuffs

[gentle urchin]

If all else fails, you can always block the tick one with a gate 😅 not something i'd do unless i was desperate

[remote meteor]

chorded action should only trigger once i believe? 🤔

if a normal key, the trigger action should be changed to pressed for a single fire of action

[wicked cairn]

Anyone know a way to have my Fishing Bobber Actor get buoyancy applied to it when it's interacted with a Physics Volume with Water Volume enabled?

I have a Buoyancy Component added to it and set its Mass and Linear Dampening but it does not float on my Physics Volume, only the fish can, which are Character bases

(2D Sider Scroller Image, the red/orange sphere is at the bottom, not the top like the fish are)

[remote meteor]

for UImage, you can get the dynamic material straight, if the brush is a UMaterialInterface, it will create one on the fly when its called and caches it.

[gentle urchin]

Handy

[young meteor]

Is that a better way of doing it basically?

[gentle urchin]

Less nodes / upkeep 😄

[young meteor]

And where is it getting the material from then? 🙂
Whatever I set it to for that instance in the widget?

[gentle urchin]

Y

[remote meteor]

though i have a feeling this function is kinda forgotten by Epic 😅

though its still works perfectly for a Material brush, it has a comment of some sort of additional feature, has a disable depreciation warning pragma, and also uses a C style NULL

[remote meteor]

the image

[young meteor]

Can't seem to find it unless I untick "context sensitive". If I do that it breaks the connection when I pick it.

[versed sun]

Target is image

not material

[young meteor]

Ah, I see.

my bad

So I skip "Create Dynamic Material Instance" and setting brush completely. Everything else is the same? (providing I remember to pick the material in the widget instance 🙂 )

[remote meteor]

you also can handle non material brush with a IsValid check before setting anything

[young meteor]

My thanks 🙏

[remote meteor]

what the node does is basically the same as what you had, the difference is, the dynamic material is created on demand and replaces the original material, so subsequent calls of GetDynamicMaterial will return the already created DMI

[versed sun]

no need to save a ref / it wont keep making new ones ?

[remote meteor]

yeah no need to ref save it, as it gets from the image's brush instead

if Material
  if !DynamicMaterial
    CreateDynamicMaterial
    SetBrush(DynamicMaterial)
    DirtyTheImageForRedraw
  endif
  return DynamicMaterial
else
  return nullptr
endif

[versed sun]

hmm, no version for Mesh Materials ? 😦

[remote meteor]

you can always make one yourself 😆

[versed sun]

ewwww, with c++ ?

sounds hard

[remote meteor]

let me check the one that primitive component has

bp would work too

this actually does work

the trick is to leave SourceMaterial empty, if its empty, it created what that index already has, if you set anything to it, it replaces what it already has, so this acts as 2 usage

it would also create a DMI and replaces it

also does the same if DMI, straight return it

you have to know which material index you want ofcourse 😉

[versed sun]

interesting

[jade lintel]

very useful

ima save it for the next time i forget what they do

[remote meteor]

though arguably, saving the DMI ref straight would probably be more performant? 🤔 but this is bp land, i guess it doesnt really matter...

[gentle urchin]

^ word

[versed sun]

But , you wouldnt have to keep track of which mesh has which material
just , whatever it has, you can change a param

[remote meteor]

but you also will need to check your own DMI ref isvalid so its the same in the end

😅

[hybrid hare]

Hi, I have a BP where I have 2 boxes acting as trigger, one for doors, one for drawers. But When I have fired the first boxes, the second become unresponsive (both have different enhanced inputs). Any idea what should be tuned ?

[versed sun]

Gona need some pics, what is a Box?

[hybrid hare]

mmmm... obviously component overlap of the second box and the first box do not work at once

box / component overlap sorry

it's two bp asssembled in one.

I used to do this that way cause it was the same control for drawers and doors

[versed sun]

When you're confused , show code you used

When in doubt , print it out

and when code is crap , take a nap

[snow gazelle]

Hello, sorry if I'm asking a stupid question, but I'm having a little problem with a blueprint that isn't working.
I'm folowing a playlist of tutorials to generate, but my blueprint isn't generating the landscape properly.
Here is my fuction to generate triangles, what it does, and what it was suposed to do.

[grizzled swallow]

what blueprint class is optimal ifi just want to have a base class with some information: image, Text, and a function to override

something like a struct

[frosty heron]

Depends on the use case but if u don't need to spawn it into the world, you can use the most generic class.

Uobject

[versed sun]

Like a struct , but flexable ?

[gentle urchin]

Uobject, aactor, bpfl,

[grizzled swallow]

Would just a c++ struct work?

[gentle urchin]

Depends™️

[grizzled swallow]

like some memebers and a pure virtual function

[thin panther]

you wont be able to use the struct's functions in bp

[frosty heron]

Can unreal struct have function in it, apart from constructor?

[grizzled swallow]

Ok so just UObject as the class?

[novel rock]

Good morning, just woke up.

[remote meteor]

c++ only 😆

[versed sun]

Can quite make out code, but make sure you clear the arrays before generating

[remote meteor]

i recommend UDataAsset if its about a collection of info about something

[grizzled swallow]

Ok let me see

[grizzled swallow]

can u inherrit from it?

[gentle urchin]

Sounded dynamic in nature

[haughty egret]

Maybe I have it set up wrong?
If I have Z as the key and the Chorded action is an input action bound to Ctrl

And I press Ctrl + Z

It sends many

[snow gazelle]

How do I do that?

[frosty heron]

I would use data asset/data table plus a class when it comes to items or weapons

[hybrid hare]

here is the door code

[frosty heron]

The data table/asset can point to my weapon class which have custom functions depending on the weapon

[versed sun]

Triggered is going to spam the Flip Flop

[snow gazelle]

So i just need to add that block before every array?

[grizzled swallow]

btw whats the difference between Text and String?

[gentle urchin]

You could manage with only one track and do *-1

[versed sun]

no, just once at very beginning of generation code

[frosty heron]

@hybrid hare better use boolean and stop using flip flop.

Imagine if you enter the level where the door is already opened.

Problem with flip flop is that it remember the state

[versed sun]

If you dont clear it , it will remember info from the last time you generated

[versed sun]

wait.. its a local Variable?

[hybrid hare]

@trim matrixsummer ok. That's why I have another set of doors for rooms that works so... I used bool . Ok 'ill have a look

[snow gazelle]

The only local vareable that I'm using is the vareable vertex

[versed sun]

yah , i think the "Triangles " array needs cleared

right before your first loop

[snow gazelle]

Like this?

[snow gazelle]

It still doesen't work

[versed sun]

what's the tutorial you are following?

[hybrid hare]

I'll also give a try with bool and branch instead of flip flop but so far it seems to be working, I've just rewrote my BP so all assets are in teh same and the same overlapping component (it seems overlapping 1 was killing overlapping 2 until I was quiting the overlapping zone and re-enter it)

[snow gazelle]

[marble tusk]

I don't know why that tutorial is making their own function to make a grid of triangles. The engine has one built in

[gentle urchin]

Imagine if this could be a simple component where you added references to, and just set a few config variables

[gentle urchin]

Once upon a time, it didnt 😅

The tut was only 1 year old tho... hmm

[marble tusk]

It's been there for way longer than that tutorial existed though

[frosty heron]

Idm some exercise to make a triangle

[hybrid hare]

well, my imagination is quite limited so far 😄

[frosty heron]

Next would be a square then rectangle

Cpp basic turorial teach how to make shapes

Fibonacci or w.e it's called

[marble tusk]

That tutorial sucks. They fast forward through the stuff you need to see, and then don't even show the final blueprint graph before moving on to the next part

[frosty heron]

Sounds like majority of youtube tutorial

[snow gazelle]

How do i use that function?

[frosty heron]

How to make rpg in 1 series 🤔 or make your gta

[pulsar pulsar]

Any tips on updating the text on a Interaction prompt during the interaction? So for a door, when it is closed it says F To Open but I cant get it to change to F To Close until I look away and look back at the mesh. I'm using a Custom Event inside the widget where I do Set Text and then call that event when needed. So far I have it so the text updates wether the door is open or not. But the text won't update itself unless i look away and look back at the mesh

[thin panther]

I mean I have my reservations about a tutorial doing full proc gen in bp anyway :P

[snow gazelle]

It was one of the only tutorials i found

[frosty heron]

You can use delegate to update the information

[gentle urchin]

Have you seen my 1h mmorpg complete tutorial?

[thin panther]

what you're asking is not a beginner topic, and assumes experience.
hence you won't find a tutorial

[gentle urchin]

Its 14000 hours distilled into 1

[frosty heron]

In blueprint too I bet

[thin panther]

it's very much one of those things where if you're at that stage to do it, you don't need a tutorial

[frosty heron]

I saw how to make elden ring combat in short video

He did all the attack anim in anim graph

Real garbage

[pulsar pulsar]

As in Bind and Call events?

[gentle urchin]

What is a good tut without blueprints

[thin panther]

please tell me you do everything in the best blueprint.... the level blueprint

[frosty heron]

Yup, you can broadcast everytime u finished open or close door

[gentle urchin]

I actually hide it in my ticking native landscape, yes

[frosty heron]

Where do you keep the info for the door anyway?

It should be in the bp door

[pulsar pulsar]

Oh shit yea, I did try it but I probs didnt do it right. I'm gonna give it a go when I get back to my PC

[pulsar pulsar]

Is there even any tuts without BP 😂

[frosty heron]

I assumed u are doing trace every tick anyway right?

So just read the current state of the door

[pulsar pulsar]

Yes indeed

[frosty heron]

Just read rhe current state of the door. If open set text to open if close set text to close

[pulsar pulsar]

Good idea!

[frosty heron]

There are, some are gem. Not gaining as much subscriber tho

[pulsar pulsar]

Understandable I suppose. Blueprint is quite friendly to a brand new user. I tend to stay away from tuts unless I'm really looking for something I cant figure out myself

[frosty heron]

If I must start from the bottom, I would look at these ones

[young meteor]

Are there no blueprint node for a simple blur effect in materials?

Trying to find a simple way to create glow effects in UI

[crude spruce]

glow and blur are different things

and glow is not glow effect

[versed sun]

Glow = Emissive

[frosty heron]

He is trying to do it in UI material tho

[young meteor]

But for UI

[frosty heron]

Download Material lab to see how it's done

[crude spruce]

blur in UI isnt glowing. its blurring 🙂

[frosty heron]

I can't dechyper most of them cuz I suck

But they covered how to do glow

Where is autheur when you need him 😔

[young meteor]

Okay. I'm trying to create a blurring effect simulating glow when I add color later then 😛

[crude spruce]

[young meteor]

How dare he take a day off on sunday 😄

[frosty heron]

He's been mia

[crude spruce]

in UI ?

[frosty heron]

Anyway download material lab

If you need to see how things r done in UI, including glow

[young meteor]

Already did. Just wanted to avoid getting new engine version too if I could. On 5.0

[frosty heron]

Pretty sure 5.0 is fine

[young meteor]

Still a good point though.

[frosty heron]

It's not easy like 3d material

[crude spruce]

still unclear if this is UI or not 🙂

[gentle urchin]

It is UI

Widgets

[gentle urchin]

Unless you have plugin you cant directly do glow in UI tho, can you

[crude spruce]

@young meteor
Are you thinking about radial blur that can work as a glow in 2d software like photoshop ?

[dawn gazelle]

I wouldn't even say it's blurring, it's more like an alpha blend out.

[young meteor]

There is a "SpiralBlur - Texture" node. Not sure if that is an option yet.

Need to investigate it a bit more. Doesn't seem intuitive.

[crude spruce]

its double plus good to be very specific 🙂
not that its easy but it helps to find solutions eventually

[young meteor]

Or gaussian blur is commenly used in Photoshop. Would do the job I think.

[crude spruce]

ay i used to do neon type effects wth the blur tools

[young meteor]

Actually I could just blur it in Photoshop and import a new Texture with blur. Seems stupid though. There must be a better way. 😄

[frosty heron]

Blur is just an average of neighbouring color I think

Mathematically

[crude spruce]

wasnt many special effects here eh eh

[young meteor]

Hmm. Are you saying you kinda solved blur with math?

[crude spruce]

shaders are math

[versed sun]

computers are math

[young meteor]

life is math

[crude spruce]

math, not even ones!

amirite

[dawn gazelle]

It depends on the "shape" of the glow that you want. Like, if you wanted something like this where it looks like it's glowing from the bottom, that's just a gradient that's being overlayed

[frosty heron]

Ive been struggling on making glowing font 🫠

[remote meteor]

i end up just use a blur outline as the glow

😂

[frosty heron]

Gave me idea. I might try that later

[young meteor]

It's annoying, because when I open up their "Spiralblur" node the preview is pretty much exactly what I want

Just can't get it to do the same for my texture.

[barren drum]

Hello, is there any simple way to get the "UWorld" object as a reference in a bluprint?

[frosty heron]

Any particular reason to get the world ?

[barren drum]

There is a static Blueprint API that needs the UWorld as a paramter

Like "static UObject* GetSomething(UWorld* World);"

[frosty heron]

Never try to get it in bp. But if I must I prob will make a function that return the world from cpp

[young meteor]

Oh it actually does. Just not in my live node previews.

This works with a Texture Object, but I don't have an option to "clamp" values in an object.

Any good ideas on how to get around it?

[barren drum]

@frosty heron Ok. I assume you can't get the UWorld in a c++ static implementation?

I mean one way would be to just remove the reference entirely and internally just get it from a global or so.

[frosty heron]

I don't see why not. Maybe can even do it from static library

GetWorld()

Return

[barren drum]

'UObject::GetWorld': a call of a non-static member function requires an object

[frosty heron]

Where do u get that error?

[barren drum]

compiler

[frosty heron]

How about get the game instance and get the world from there

@dawn gazelle Would know more

[barren drum]

You need UWorld to get the game instance

UObject* UCommonFunctions::TestGetter(UWorld* World) {
    if (!IsValid(World))
        return nullptr;
    //GetWorld(); // generates error
    UGameInstance* GameInstance = World->GetGameInstance();
    return GameInstance;
}

[frosty heron]

U want to return world

[dawn gazelle]

UObjects don't have a world context.
You can give them one, but you have to feed in an object that has one.

[frosty heron]

Instead of passing?

[barren drum]

class MY_API UCommonFunctions : public UBlueprintFunctionLibrary
{
    GENERATED_BODY()

    UFUNCTION(BlueprintPure, Category = "Common")
    static UObject* TestGetter(UWorld* World);

[dawn gazelle]

#blueprint message

Static functions are similar. They won't have a world context unless you're able to retrieve one from something.

[barren drum]

gosh... test again... I got lost in histor

[golden gull]

I am using enhanced ability system, I have an E key which interacts with something, I set it as a digital (bool) value type. Problem is if I hold the E key then it will keep interacting again and again. How do I make it so that the key only works once per press, so that holding the key doesnt retrigger the functions?

Ah I need to connect not from triggered but from started

[barren drum]

ok thanks... so I have to pass any reference object that has "world"?

it can basically be just a plain UObject*?

[dawn gazelle]

If the UObject has a world context. by default they don't

[barren drum]

gotcha... thanks I was planning to do a convenience function for GetGameInstance

I always have to convert it into the custom GameInstance and the blueprint just looks very bulky that way

i.e. GetMyGameInstance() in c++

[frosty heron]

Make a pure function that return your game instance

[barren drum]

Yes, that is what I try

[frosty heron]

Save your self from casting

[barren drum]

but to get the game instance I need UWorldd

[frosty heron]

In blueprint?

[barren drum]

c++

[dawn gazelle]

Look how the built in one works:

    /** Returns the game instance object  */
    UFUNCTION(BlueprintPure, Category="Game", meta=(WorldContext="WorldContextObject"))
    static class UGameInstance* GetGameInstance(const UObject* WorldContextObject);

class UGameInstance* UGameplayStatics::GetGameInstance(const UObject* WorldContextObject)
{
    UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull);
    return World ? World->GetGameInstance() : nullptr;
}

All you'd need to do is basically change the return type and cast.

[barren drum]

I guess I could dig into the implementation of GetGameInstance

[remote meteor]

you usually use WorldContextObject isnt it

then get UWorld out of it

in a FunctionLibrary

[barren drum]

GetGameInstance is implemented without any UWorld object reference

[remote meteor]

see the function above

it gets the UWorld from the WorldContextObject

for a bpfl, it will be wherever the function node is used

[dawn gazelle]

Yeah if it's being called in an object that has a world context, it shouldn't prompt you for a world context object, but if it is within something that doesn't have the world context, then you'd have to feed one in.

[remote meteor]

anyway i have another method to handle autocasting

[barren drum]

it's just nothing but instead of this

[remote meteor]

UFUNCTION(BlueprintCallable, meta = (AdvancedDisplay = "ClassType", ClassType = "GameUserSettings", DeterminesOutputType = "ClassType"))
static UGameUserSettings* GetExtendedGameUserSettings(TSubclassOf<UGameUserSettings> ClassType);

the ClassType will determine the return type

[remote meteor]

just like the GetComponentByClass node does

[barren drum]

I just want a "GetPlaformGameInstance()" without requireing the conversion exactly everywhere I need it

[frosty heron]

Make a pure function

In blueprint function library

[barren drum]

without any parameters if possible

otherwise I just stick to converting it

[dawn gazelle]

    /** Returns the game instance object  */
    UFUNCTION(BlueprintPure, Category="Game", meta=(WorldContext="WorldContextObject"))
    static class UPlatformGameInstance* GetPlatformGameInstance(const UObject* WorldContextObject);

class UPlatformGameInstance* UYourLibraryClass::GetPlatformGameInstance(const UObject* WorldContextObject)
{
    UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull);
    return World ? Cast<UPlatformGameInstance>(World->GetGameInstance()) : nullptr;
}

[remote meteor]

if you are too lazy to even select the class you want then i dont know if there is anything that is dynamic

just make one specific casted for the ones you need i suppose

this is acceptable to me as its one node for all possible classes

[barren drum]

Maybe this can work?

    GEngine->GetWorld();

[pulsar pulsar]

It worked, cheers man

[frosty heron]

Since u do it every tick make sure to not do something that's already dobe

Done*

For example if open and if text is already "open" do nothing

Otherwise u might be calling set text every frame

[pulsar pulsar]

Ahhh! Very true!

[frosty heron]

Which maybe insignificant but some node is just heavier. If you want to guard Ur fps, it's better to do micro optimisation

[dawn gazelle]

All objects have a GetWorld() function, but it doesn't mean they have the world context.

[frosty heron]

Make a function out of this for your blueprint problem. Plug the cast result and return it

Then you can call getmygameinstance function instead calling getgameinstance function

[dawn gazelle]

Note the lack of defining a World Context Object anywhere.

What is happening is that it tries to get the world context automatically from the thing that is calling it.

[frosty heron]

Only works if called from actor then? Or not really

[remote meteor]

anywhere where a function library is usable

[dawn gazelle]

Basically... or anything that you've been able to give a world context to.

[frosty heron]

0o 👍

[remote meteor]

function library only shows up when GetWorld() is resolvable anyway

[dawn gazelle]

This is the C++ equivalent of what I have above in blueprints. #blueprint message

[frosty heron]

I use the kismet library to get the game instance, never dug deeper

And made a function in bfl to return my gameinstance

[remote meteor]

it looks like this

[frosty heron]

Saved me once more 🙇‍♂️

Material font?

[remote meteor]

outline material

font is just plain text

[versed sun]

Mine isn't quite the same ...
How big is your outline size? anything i missed ?

[remote meteor]

my size is 8

but yeah, more or less thats the closest i have ever gotten to a font glow

😓

[young meteor]

Can't believe there is not a default glow option ^^

[versed sun]

It's the way she glows...

[remote meteor]

time to request photoshop feature into unreals

here is one with roboto bold

certainly some weirdness..

and it also affects the widget desired size

[gentle urchin]

That g and o

Really stick out

Any closed space really

[remote meteor]

i just want glow like this 🥲

[gentle urchin]

Theres a plugin

[young meteor]

Feel like one could set up a loop function for a translucent material that do X passes of:
Increase UV size by 0,0X (loop integer), set opacity to 0,01 (not sure about value), and add it to final color.

So in other words, expand the texture slightly X times (slightly bigger every time), with a very low opacity, and add them all up in the end, to fake a gaussian blur with X "rings" of glow. Faking a gradient.

Sounds way off?

[gentle urchin]

[marble tusk]

Hmm, I think there is a gaussian blur panel in UMG which you could put a copy of your text behind in order to get the blur, but it would also blur everything else behind it

Unless you're fine with settling with a blurred box around your text

[fervent zenith]

Hey i have a problem im trying to spawn a player and possess it to the player controller so that the user can controll it the only problem is that the server can not move arround but the client can why is that?

[manic cove]

When i do "Get Player Controller > Posses" i can't move and no inputs work, how do I restore inputs to a posses pawn?

[frosty heron]

Sounds like u have the same problem as the person above

[manic cove]

mine isn't server/client, doesn't move at all on client, but interesting it's very similar 😄

[frosty heron]

Single player yeah?

Perhaps his problem isn't multiplayer related then

Normally possessing a pawn just works. But I'm not sure how inputs are handled with the new input system

[pine idol]

Anyone have any ideas for this?

[manic cove]

Think that might be it, I'm using the new Enchanced input, if i add a basic "num 5" trigger it works, if i add a Enchanced Input for num 5 it doesn't work when posses..

[frosty heron]

It should be implemented on begin play, look how they add the maping context etc

[manic cove]

Not sure what you mean

[frosty heron]

You might need to run that after the On possessed event I'm not sure

Look how enhanced input is setup

[manic cove]

Oh the assignment of enhanced?

Yeah that is fine

If i enable auto posses everything is fine and dandy

it's when i posses through BP

[frosty heron]

I can't comment much cuz I'm still stuck with 4.24 lol

Yeah try to run the assignment after posses. See how that go.

[manic cove]

OHH

@frosty heron that was it, so on begin play i checked for player controller and map controls, when not auto posses theres no controller so it doesnt set

dohh

thanks for the help 😄

[frosty heron]

@fervent zenith check out what he do. Sounds like Ur problem too

[manic cove]

i threw a print on this after what you said and it was apparent, so now after posses i just re-run this function

might help! @fervent zenith ?

[fervent zenith]

oh you just created a new function inside the player character class and after possess recall it?

[true oriole]

how do i access a widget that is one of my actor component ?

[frosty heron]

Wdym? Try to show some picture

[fervent zenith]

@manic cove IT WORKED

damn

thank you

❤️

[manic cove]

Wooo! and thanks @frosty heron 😄

[fervent zenith]

@frosty heron we love you ❤️

[dawn gazelle]

Get HealthBarWidget > Get Widget > Cast to your Widget's Class > Do stuff with your widget.

[true oriole]

it works! thxx

[fervent zenith]

the funny part is that my player character class is written in c++

[true oriole]

i use ue to avoid coding

:LULW:

[fervent zenith]

what is ue?

[true oriole]

Unreal Engine

[fervent zenith]

huh? you mean Blueprint

Unreal Engine is the engine

[true oriole]

ya i meant i choose unreal engine over other engine like unity/dogot to avoid coding.

[barren dove]

hey folks am I doing this right?
I'm getting "shot" events
but the npc doesn't appear to be recieving the event

[fervent zenith]

i see yea im using mostly c++ because i like it to code and blueprints are sometimes harder and limited

[true oriole]

shouldn't u use event any damage( the built-in one)?

the one you using is created by you

[barren dove]

i am, thats what it created

thats on beginplay

[true oriole]

don't you need to connect the damaged actor ?

[barren dove]

for what, if it recieves the event, it is the damage actor

ah ha, there's also an "anydamage" event which is... the same thing(?)

[true oriole]

no idea, but normally if i use apply damage i will use event any damage

i never use the bind event node no idea how it work lol

[barren dove]

yeah i slapped that in there and it still isn't firing the print string i'll keep messing with it

[true oriole]

i use interface

[barren dove]

I dont know what that means

[plush hornet]

Hi all, anyone got any suggestions on how to do a charge attack and a basic attack from the same input? Not so much the mechanics of it as ive got that figured out, just how would i get it to work from an enhanced input action without them conflicting? Thanks

[true oriole]

u can just cast to the enemy blueprint and call any custom function in the enemy bp, or use interface

[barren dove]

yeah I could make my own custom event and event dispatcher and build everything from that
