blueprint

[pine tangle]

so the sampling of the beginning and ends are memory contiguous (or any vertical strip)

you would also need active objects to reassign their bucket or bin every physics tick if you wanted full 2D coordinate wrapping solution

pros and cons to each method

It might actually make the most sense to dupe the player and do the force add haha

that just sounds like an issue waiting to happen to me though

[gentle urchin]

Or

Crazy idea

Rotate the tower 😄

/world

[pine tangle]

That doesn't solve the fundamental issue

You will be jumping on 2d coordinates and not in 3d

also lining up the shader could be a hassle without using high floating point precision

I've become partial to the full 3d solution, and then just squared distance checks for things like enemy aggro, it sounds a little redundant, but it will almost certainly be less work on the developer and CPU in the end than a bunch of conditional coordinate wrapping imo

dont even need the sqrt here in basically every case

and when you do, since he is using the Unreal Physics for collisions thats all internal anyway

[gentle urchin]

And youd reduce load by only moving relevant objects during the rotate

Some section abive and below the player

Smoke and mirrors

[pine tangle]

no point in updating the world transforms or any object transforms, the full 3d solution with a custom coordinate mapping just for the character and active object placement, updating what should otherwise be static positions comes at a heavy cost that is difficult to overcome unless you've done some insane prebatching

[gentle urchin]

Feels like it'd be an easier feat than the alternativez but ive never tried any of them

Ive seen amazing things happen in the shader so

[distant hollow]

This is my door frame

And my code to mirror flip it

However, when flipped, it became like this

But when the structure was saved and reloaded, it looked fine
What could be causing this issue?

[pine tangle]

@floral totem Im pretty sure this is what you're looking for

and then depending on how you want the input and movement handled, if you do them indepedently of the physics tick you will also need to reapply the location but not velocity

this is also assuming your velocity has been either frame delta or tick adjusted

[glass crypt]

hi, i have a camera system that periodically spawns cameras in different locations around the player and switches between them after a small period of time. this acts as a cinematic camera mode that provides the player with different angles to view the player from.

however, i'm having an issue where after a while, the player's character controls get reversed, so instead of forward moving the character forward, they move it backward. the same issue happens with right and left as well.

i'm using the default controls from the 5.3 third person template.

how do i make it so the character always turns left when the left button is pressed, and always moves forward when the forward button is pressed, etc? thanks

[gentle urchin]

Could the control direction be flipped?

[glass crypt]

it seems like that is what's happening

[gentle urchin]

Add some print strings to verify the problem

(Phone fingers, sorry)

[woven turret]

I'm unable to access it via a Blueprint node in the same way you can change the Light Intensity property, etc of a Directional Light's Light Component, C++ isn't an option here unfortunately

We use a dynamic Directional Light, it still lets me adjust the Shadow Amount manually in the level's DirectionalLight, but I would like to access it via Blueprint also to emulate overcast/cloudy lighting for use together with weather effects

If there's absolutely no way bar C++ I'll just look into other methods I could emulate this effect

[pine tangle]

"Set Intensity"

[gentle urchin]

You can access set shadow amount in 5.3.2 atleast

Takes a directional light component as target

[woven turret]

This isn't the effect I'm looking to achieve as I still need the lighting from the sunlight 😅

I found a way to do it by just adding the DirectionalLight as a component directly into the same actor I handle the weather system in, rather than accessing a DirectionalLight in the level, this lets me set the Shadow Amount as a Blueprint node.

No clue why it doesn't let me do it the other method, but this method is more streamlined anyways with what we're doing

[timber crystal]

I have built a respawn trigger here that only works as soon as my player comes into the trigger area. It should be noted that this only happens once

But what I want is that as long as the player is in this trigger area, the opponents come every 2 seconds

Waht have i made wrong?

[gentle urchin]

you'd need to get the component from the directional light actor

[woven turret]

It never gave me the option to access the Shadow Amount even if I did

[woven turret]

We avoid using casts in this system

But I figured out a solution regardless, thanks for the help 😄

[gentle urchin]

Just letting you know why it didnt work ^

no worries

[worthy frost]

avoid casts ?

why?

[gentle urchin]

Casts are haunting projects left and right i guess

Tutorials have made the myth a truth

[dark drum]

Over using BP Interfaces isn't a replacement for casting. I say that as I see a lot of people that have been told not to cast and use interfaces instead.

Just casting to a DirectionalLightComponent would be better than any other solution in this case.

[gentle urchin]

Create a delegate in the daytime system that sets shadowamount ,
Subclass directionallight (or your own actor) and register to this delegate

Win winn

Add an additional gameplaytag to the delegate, and you can now filter them aswell 😄

[dark drum]

You still got to cast to be able to bind to the event dispatcher.

[gentle urchin]

You could interface it, but yes. Just cast

Odds are the daytime system always exist

(Interfacing it doesnt make sense)

[dark drum]

Yea, people forget the overhead for using an interface.

[sonic arrow]

Alright so im trying to make a gun system for my game, I want there to be around 10 - 15 guns, how would I make the gun base and the children attached to that?

[gentle urchin]

Gun base would have the functionality / events, but zero asset references , the subclasses would overriding the necessary events (if any) and providing the assets and actual config for the gun

Bullet to use, spread rules, projevtile speed, mag size, reload speed, animations related to this (?)

[sonic arrow]

damn, you'd think id know more of what you're saying, it has been 3 weeks since I last worked on my project and Ive managed to forget so much, currently im doing a yandere dev solution for the prototype. ill try and figure that out though for the actual game

[gray ingot]

Hi, why my door works normally only from second time i open it? To the right is door with the same code, but it does work from first opening

[sonic arrow]

its the animation, more specifically the close one

I had this issue before as well, ive forgotten specifics

[gray ingot]

But they are the same...

I use timeline

[sonic arrow]

should be the time to play the animation, might be causing it to bug out on first open/close

[gentle urchin]

show code 🙂

[sonic arrow]

ik thats the weirder part, ive never seen that specific issue

[gray ingot]

xD

[gentle urchin]

first door starts in the wrong state

so it think it's open, while its actually closed

Also, you should consider "play" and "reverse" and not play from start / reverse from end

[gentle urchin]

rip xD

[gray ingot]

Hahahhahahah

[gentle urchin]

this is such a mess

[gray ingot]

My variables are the same

[gentle urchin]

like what the actual f*

reverse from end is being played

(but no wonder there's no control here 🙂 )

[gray ingot]

I played some satisfactory

[gentle urchin]

Do yourself a favor, and start being more organized, from this very moment

Clean up this mess

[gray ingot]

Yeah, i actually do organize from there

[gentle urchin]

Split it out in a few different events

"Unlock Door"

"Open Door"

"Close Door"

[gray ingot]

Like this

[gentle urchin]

I would barely call that organized ,but sure

somethimes it gotta be like that

[sonic arrow]

yandere dev code 👍

[gray ingot]

Yeah, i know about my "pro skills in bp"

[sonic arrow]

if then = if then = if then = if then

[gentle urchin]

switch on int

[sonic arrow]

wdym?

[gentle urchin]

embrace it

[sonic arrow]

embrace int?

I ❤️ int

[gentle urchin]

embrace the switch

[gray ingot]

Is it the problem?

[gentle urchin]

instead of

if
else if
else if
else if

[sonic arrow]

is there actually a switch?

[gentle urchin]

It's hard to say, because it's so messy

[gentle urchin]

yes

[sonic arrow]

that would clean it up a bit, most of the ints are for ammo calculation but the top set current gun and get current gun should look better

[gentle urchin]

but Im not sure why your BP is doing ammo calc for a bunch of different weapons

ammo count would be in the gun

[sonic arrow]

yandere dev, all the guns are in the player rn

they go visible when active

def good for performance

[gentle urchin]

I cry a little

but alright

Switch on int atleast

and wrap in functions

"HasAmmo()"

"ConsumeAmmo()"

looks far cleaner, and is actually readable at a glance

[sonic arrow]

okey

ill remember because I gotta go to school, thanks for the minor tips

for yandere dev unreal engine experience

because im so good at script communication and defenently have a grip on reality

[sonic arrow]

why is has ammo = float

it look like float

[gentle urchin]

its a pure function

[sonic arrow]

huh

[gentle urchin]

point was, do yourself a favor and try to keep it readable, and easy to understand whats doing what

[sonic arrow]

its crazy how much I forgot

[sonic arrow]

fair

[gentle urchin]

makes it so much easier when you get back in a year

trying to fix some bug or whatever

[sonic arrow]

thats crazy

Im hoping in a year im better at putting thing together in code

and not doing yandere dev code 24/7

[gentle urchin]

Separate the functionality into it's own steps.

[gray ingot]

Yeah, i know how to organize, but i think i will spend more time organizing then solving the problem

It seems like obvious thing

But i don't really see it

Could it be that my door is mirrored?

[gentle urchin]

its easier to see when organized

thats the entire point 😄

[gray ingot]

Yeah, i know)

Sec, i will try my best to make it easier to read)

[timber crystal]

Does anyone know why this doesn't work?
I want the platforms not to be displayed in the game as long as the opponent has 100% life (not dead).

[gentle urchin]

Is it triggered at all?

[timber crystal]

i tested with print one sec.

[timber crystal]

yes but this time with an error

[gentle urchin]

So the variable is null

are you setting it to an instance at any point ?

a variable is just a cointainer to something. In this case its a container for a reference to an instance of the BP_Platform Grass Hidden

[timber crystal]

I realized that I didn't build the whole thing into the platform, but rather into the character that has to be defeated
if you mean this with instance

[timber crystal]

ok so i need to try it with an variable right?

[gentle urchin]

you need to set the variable

with an actual reference to the thing you're trying to hide

[timber crystal]

ok thanks let me go for it 😄

[gentle urchin]

So you can either:

• Hardcode the value in the editor
• Somehow trace/collide for it (if it makes sense, probably not )
• Operate through some common actor / event manager of sorts , where all platforms could register themself to it
• Use the 'hacky' GetActorOfClass , altho this returns an unknown instance, if there are several

[timber crystal]

thanks a lot Squize!!!!

[gentle urchin]

xD

[gray ingot]

I did my best

[gentle urchin]

Cmon

you can do better

like, really? xD

[gray ingot]

xD

[gray ingot]

But what should i say xD

[gentle urchin]

If that's all there is to say, then nothing

DoorClosed = Direction==Backward

Otherwise you're missing an update

[gray ingot]

Yeah, but my door does work but first open

Only first open bugs out

[young meteor]

I'm trying to use a Sphere Overlap Actors function. I've set Object types to "Pawn".
It is not finding anything. The Actor I'm trying to have it find has a parent class of "Actor". Could that be why?

As opposed to parent being "Character"?

[gentle urchin]

gotta check the collision settings,

but usually, only pawns or subclasses of pawns would be of the object type pawn

[young meteor]

I'm trying to find my "towers" in a TD. What is the best option then?

WorldStatic/WorldDynamic?

[gentle urchin]

Dynamic i guess ?

[young meteor]

Or is the correct approach to change the type of my towers instead?

It is not a Character moving around though.

WorldDynamic works. Guess that is better than Static then. I would think Static means it is also checking all kinds of, well, static items 😄

[gray ingot]

I really can't see the issue

[gray ingot]

It does work fine

I am so fk stupid

I've had my door inside my actor at 90 rotation

and it fk all up in my lerp

Sorry for this :/

[gentle urchin]

first thing i mentioned

wrong state 😛

[narrow pendant]

hello everyone, I'm trying to store a reference to a widget in a savegame object. what I want to do in the end is store which of these widgets is currently solo'd. however when I load my savegame object, the stored reference to the widget is None. I assume it's because the widget is temporary and the object ID changes everytime it gets created (or similar?)

[queen heron]

how are you setting the savegame in blueprint?

why does the Interp To Constant node becomes faster if the interp speed value is lower than 1?

[gray ingot]

Yeah, sorry for this...

[versed sun]

you can't save a Ref of an actual widget, but you can save info on how to re-make it

[narrow pendant]

like this, I've got a few structs that I mirror to the savegame object and then save it to a slot

[narrow pendant]

I see, that's what I suspected... is it because they're pointers or sth, do you know what the reason for that is?

[versed sun]

i think thats it , it would be looking for the EXACT widget

[narrow pendant]

right...

alright thanks gonna work around it then

[dark drum]

Yea it's because they're like pointers and that object no longer exists after you've closed out and restarted. This is why the reference becomes null.

You can technically get it to work but it's unreliable so there's not much point exploring it. Much easier to recreate the object from saved data.

[mild pine]

How can I make a FinterpTo's Interp Speed match a Timeline's Time? For instance, when I set a new length for the Timeline I want the interp to take that into consideration, but with a fixed value of Interp Speed it'll get the value per Update to it's target too fast. I might be doing something wrong, but would love some advice on this

I'm setting a Niagara's User Parameter "Size" with the Finterp, and the Size is supposed to be at it's max value when the Timeline ends.

[dark drum]

What even is this?

[spring rose]

Can anyone point me in the right direction? It's a new day and opening Unreal Engine 5, the blueprint contents of my projectile are gone and yet when i run the game, it still fires and does what it's supposed to. What's going on here?

[versed sun]

make sure you don't have 2 BP_Projectile blueprints

[spring rose]

I don't D:

[versed sun]

in your Content Browser

like the file itself

[spring rose]

This?

[versed sun]

you could have duplicated it accidently

[spring rose]

It's got to be somewhere. When i run the game, it does what it was blueprinted to do 😒

: s

But searching for projectile, that's all that's there in the entire content folder

[versed sun]

go to whatever spawns the projectile and click the magnify glass

it will take you to the blueprint you are useing

[spring rose]

Uhmmm. I'm following a lecture and the spawn was in the BP. It was a spacebar event, does that sound right?

Yeah, looking at his now, space bar > spawnactor BP_Projectile > add impulse (plus get play pawn, actor location, control rotation, actor foward vector and static mesh component)

All of that was in the BP of the projectile that's no longer there but somehow still runs

You know what, last night i changed these two things so my tester map opened first, is this maybe the issue?

[obtuse mulch]

it seems like you have all of the logic in player pawn lol

[spring rose]

If that's in reference to me, i don't know. I'm following a beginner lecture.

That being said, my BP_projectile isn't in any other map, so i can't see how me changing what map opens when unreal launches would do anything but somehow, it's still calling it from somewhere

[wicked osprey]

Hello, guys. What filter can you write in the content browser to get assets without references?

[lofty rapids]

you took out some code and it still runs ?

that makes almost no sense

[spring rose]

I didn't take out anything, it's just not there.

Spawns and shoots just fine.

[lofty rapids]

whats in construction script ?

[lofty rapids]

so did you put code in there and it disappeared ? or you just didn't put anything in there yet ?

[obtuse mulch]

show the code after spawnactor in ur character

[spring rose]

You can see the ones with blueprints. The crates are empty and there's only one projectile. I can't show you blueprints/code because it was in the projectile and i'm saying it's empty...

The crates don't have any blueprint stuff inside of thme, so ignore them*

[lofty rapids]

so you put code in the projectile, it still works, but it's gone now ?

that sounds f'd

[spring rose]

^

That's exactly what i'm saying, yeah

[lofty rapids]

do you have multiple projectiles ? you sure your looking at the correct one ?

[spring rose]

The lecture had us put the blueprint code in the projectile, now whether that's what you would normally do as an experienced coder or not, idk. Maybe they're dumbing down the content to not overload us, but that's where it was and when i open it, nothing was there (except the 3 red default events like uhh what was it... game tick, game start up etc?)

Says there's only 1

[lofty rapids]

hmm, i wouldn't be surprised if it's a bug, i seen a couple while on here

[obtuse mulch]

you didnt save it then

what the projectile in the level has to do with anything anyway

[spring rose]

So why does the code work then lol

[obtuse mulch]

how does it work?

does it fly or deal damage or what

[spring rose]

It spawns on spacebar, fires, shoots foward, has garvity, etc etc

[obtuse mulch]

if its there in the world doesnt mean it works

damn its impossible

[spring rose]

Just reopened the project, this is what i'm met with:

But it still runs all the code from the blueprint i did yesterday lol

[obtuse mulch]

whats in the function?

[narrow pendant]

there's a 99,9% you fucked up somewhere 😄

[spring rose]

Shoots and bounces around lol

[obtuse mulch]

you have a function there

[spring rose]

scroll up slightly, its nothing

[lofty rapids]

make a copy of it, does it have the code ?

[spring rose]

What i assume is the base construtcion script node that's always there beacus ei never made it

[lofty rapids]

weird that it would still run code that doesn't exist

somethings f'd

[obtuse mulch]

this?

[spring rose]

It also doesn't have the code, weird

[lofty rapids]

but what does a projectile do with no code anyway ?

[spring rose]

yes

[lofty rapids]

it'll still move right ?

[obtuse mulch]

its construction not the function

[spring rose]

It blocks me from screenshotting his blueprint but this is what his looks like and what mine did too

space bar > spawnactor BP_Projectile > add impulse (plus get play pawn, actor location, control rotation, actor foward vector and static mesh component)

[lofty rapids]

that code would be on the character

most likely

or the player controller, usually the keys are not on a random bp like that

[spring rose]

I double clicked the function but it just drops and opens the functions list, doubleclicking the constriction script shows me the screenshot i referenced before

[lofty rapids]

you probably wrote the code in the player

[spring rose]

It's the earliest parts of a lecture so i assume they were keepign it basic, we haven't gotten to actually "making" anything properly yet

[obtuse mulch]

wdym function list

[spring rose]

Look in your or my screenshot, the word "functions" appear about "construction list"

Maybe i'm confused, what specifically did you want me to check/open

[tired whale]

Hey guys,
Is there a way to get something that ressembles the old Play Montage node?
I need to execute some actions based on a notify in my montage but atm I cannot find how to access the notifies like we used to...

[obtuse mulch]

ah ye sry

couldnt see the funcion name

too smal

[lofty rapids]

i mean you can use on notify begin and check the notify name, but can't youo put the events actually on the animation or something ?

[spring rose]

I can redo it all, help me remember and practice it anyway but idk where it's still calling the code from lol

[lofty rapids]

you probably did it in the character not the projectile

you'll probably see where it does spacebar, add impulse

[spring rose]

There is no character

[lofty rapids]

hmm, did you check the controller ?

[spring rose]

On the right, in the outliner you can see what has blueprints.

[tired whale]

If there's an event on the Animation Sequence, it'll still be there in the montage?

[lofty rapids]

i've only used notify a couple times, so i can't be of much help

[tired whale]

This used to be a really simple thing with the previous Play Montage node that provided all the exec outputs needed. The current Montage Play (guess switching the name order changes everything 😅 ) there's close to nothing... It only returns eighter the length of the montage or it's duration

[gentle urchin]

Theres two nodes

'Old' node still exists

[tired whale]

How do you access it? I've turned off "context sensitive" search and it doesn't pop up

[obtuse mulch]

play montage

[tired whale]

I should note that I'm not trying to play the montage on a Character's mesh though... so I'm not even sure that the 'old' node will do the trick...

[tired whale]

doesn't show on my end

[obtuse mulch]

what blueprint type is that

[tired whale]

actor

[lofty rapids]

play anim montage ?

[tired whale]

This one targets a character, which my skeletal mesh comp is not part of

[lofty rapids]

ya still doesn't have it

[spring rose]

Guys, i clearly didn't get enough sleep. I didn't realise that it was in the event graph of the level itself. I went back through the lecture to see what he opened it from and it was just the levle blueprint button which i forgot was there because i'm still new and dont remember where everything is. I figure from you reaction this code wouldn'tnormally be inside the projectile so i was confused too. Sorry for the issues guys!

[lofty rapids]

but i thought you can put the notify events on the animation @tired whale

or the montage

[tired whale]

I can put notifies, yes. But I can't find a way to know when they fire...

[obtuse mulch]

bro they teaching you doing projectiles through level bp

😄

[spring rose]

Just to gain a basic understanding. I know we'll move on to doing something more concrete and tell us where things normally go.

I understand keeping things simple for new people and it's ok to teach like this sometimes, i get it.

[lofty rapids]

my first tutorial i used the level bp as well

but so far i have not had a good use for it

[narrow pendant]

1. be aware it exists
2. never use it again unless you know why

[spring rose]

My brain is the worst, too. If i don't understand something ENTIRELY like, a sphere, seeing all sides, one missing jigsaw piece and it won't click for me. So when i don't understand the entirety of a blueprint for example, it doesn't click. I need to know exactly everything i can do with one piece first before I can understand it. Great when i know, bad when i don't lol

[tired whale]

I'll explain in a lengthier way what i'm aiming to do.
I have a widget setting the visibility of a skeletal mesh actor to true via a "middle man" BP actor. The BP actor, called Manager, has references to all my skeletal actors.
The widget communicates the manager which one of the skeletal actors to set to visible, and to start playing a corresponding Montage. Also, some skeletals have a static mesh attached to one of their bones (character holding a glass for instance).
Now, on a specific mesh, with a specific montage, I want the attached static mesh to be visible during a period of the montage and hidden during the rest, qnd I figured using notify would be an easy way to do so.

[obtuse mulch]

it would be

idk why you cant get that node

have you tried in other bps just to make sure?

its shows up to me even in widget bps

[tired whale]

Yup, I did so in one extended from Character, just to be sure it wasn't because the other actor is a not a character

[tired whale]

dammit, it does show up in the parent class tho, in the character, but not in the child...

But I can't access it anywhere else

I could make my skeletal actor characters, but I really don't need anything more from them than to be visible or nat, and play a looping montage...

[gentle urchin]

Play anim montage, at the bottom there?

[tired whale]

Still no
#blueprint message

[gentle urchin]

Target skeleton?

5.3.2 right?

[obtuse mulch]

in some places its even the opposite for me

[tired whale]

5.2.1 actually

[gentle urchin]

Grab a skeleton and try

[tired whale]

Wdym?

[obtuse mulch]

whats the parent class of ur bp where you trying to find it

[prisma helm]

hey guys, I'm following a paid multiplayer game course, and at event "Multicast Fire" it makes me set the player pawn not equal to owner at player index 0.
But doesn't that mean it will only work for those with player index 0?

If yes, how can I make that it changes the index based on the player?

[tired whale]

actor, it's my so called manager

it's an empty BP, holding only the variables containing all Skeletal Mesh Actors for Player 1 to 4 in seperate arrays, and another 4 arrays containing the corresponding Anim Montages to play on these skeletal mesh actors

[obtuse mulch]

idk i just created an empty actor and there it is

[tired whale]

😡 I'm in a function, and that's why it wasn't showing up

sorry guys...

[silk hinge]

Hi guys

can someone explain me this,

I have a replicated actor that cant fire a server event "has authority " is showing that it is a client, and still cant fire any kind of server event. What is the option to make this replicated actor able to start a server event ? 🤔 thanks

[dark drum]

Latent nodes (such as play montage and delay nodes) can only be placed on the main event graph.

[obtuse mulch]

and custom events, which kinda sucks

[tired whale]

Yeah, that makes sense... But I guess I wasn't paying attention to this type of stuff... Thanks anyways guys !!

[lofty rapids]

maybe #multiplayer ?

[dark drum]

The index is only applicable if you're doing local multiplayer. (split screen type of stuff)

[prisma helm]

so on networked multiplayer the index doesn't matter?

[dark drum]

No, as that node only gets the local controlled pawn of which there would only be one.

[prisma helm]

perfect, thank you very much for the information!!

[prisma helm]

is it also the same for this case? I have implemented a simple recoil system myself outside the course

[pallid sphinx]

https://youtu.be/oDKcDr6yN7U?list=PL8_QdDwbYqgSC8b3iiCuEGCkFmxl5jkOi
I don't know if anyone has any experience with this series or a general idea of what my issue could be but I've followed every step over three times now in this video and i cannot find out why i can only use the first slot of my ability inventory.
All the other systems work perfectly i can use all 10 hotbar slots and move abilities around and i can transfer abilities between the inventory and my hotbar but for some reason i can only use the first inventory slot and i cannot figure out why.
My best guess would be an issue with the array where its only letting me use position 0 but as i said I've done everything as he has from what i can see.

[tired whale]

Well, Play Montage doesn't do anything... 🥲 I don't know why, but my montage will only play if I do Play Animation. Therefore I'm back to square one and cannot know when my notify begins

[gentle urchin]

I think you can also bind to animbp's on montage completed etc

Or animinstance, cant recall which of em

[tired whale]

Thing is, I need to set the held static mesh visibility during the montage, not at the end...

[gentle urchin]

Anim notify?

[tired whale]

yup

[obtuse mulch]

does the animation play?

[tired whale]

there's this, but I have no idea what this target is

[obtuse mulch]

do a montage notify window

then use on nnotify begin and end

[tired whale]

Play Anim : 👌
Play Montage : ❌

[obtuse mulch]

doesnt play the montage?

[tired whale]

nope

[obtuse mulch]

do you have animBP allocated?

[tired whale]

the skeletal doesn't even get in position of the first frame

[obtuse mulch]

to skel meshes

[tired whale]

I don't have any ABP on these

[obtuse mulch]

u need to have it for montages to work

[tired whale]

even if blank, or does it need the slot node?

[obtuse mulch]

needs the slot node

the whole point

[tired whale]

makes sense

[obtuse mulch]

nothing else

[subtle mist]

Hey.. I have a video playing in a widget.. How can i make it fullscreen during play by pressing a button?

[lofty rapids]

can you scale it ?

i've never done that

or set it's coords somehow ?

[subtle mist]

no.. i have tried scaling the image where the video is put on but nothing.. it doesn't have size options or scale for that

[obtuse mulch]

set position 0 0 then size to viewport

you have to get the slot

wrap the image with canvas or smt

[winged totem]

Hi, is there someone that knows what capsule colors means in PHAT editor?
I came from UE4 and there's not different colors

There are green, dark green, yellow, orange

[subtle mist]

ok will try that..thanks!

[lofty rapids]

so if i have a timer by event

is a timer frame rate independant ?

do i need delta ?

[obtuse mulch]

no

timer is boss

[trim matrix]

Hello there, does anyone know what could be the reason for "Widget Switcher" to be just nonexistent from the widget palette ? nether from panel tab or search

[obtuse mulch]

you have some other stuff there

custom built engine?

[trim matrix]

Yes

[obtuse mulch]

they forgot about it

😄

[trim matrix]

It's a modified 5.1, forgot to precise it

[trim matrix]

Doubt it, we hadnt modified anything Widget sided in the engine

[lofty rapids]

but you have some custom stuff in there ?

some stuff thats not normally in it ?

or i have 5.3.2 so it's different anyway

[trim matrix]

It may come from my widget directly, I am subclassing it from UCommonUserWidget

Or just an engine bug......

[lofty rapids]

maybe#umg would have some info about it ?

[warm cloak]

my blueprint graph just disappeared in my gameplay ability blueprint :

[ancient helm]

You have to reopen the proper window (in the top left menu)

[warm cloak]

I don't get it

[ancient helm]

Now double click on EventGraph

Ah it's a different person

That's strange, you don't have a warning saying that you are seeing your blueprint as data only? And you need to click on that message to get the full view?

[warm cloak]

I do

but even when I click on it, does not work

[ancient helm]

Try reset layout in the main unreal window ? maybe your blueprint graph window is out of screen?

[rich ferry]

Oh god they do what??

[thin panther]

all sorts of bugs. their implementation is insanely broken

I've had them create null actors in the outliner leading to an engine crash, all sorts

[rich ferry]

Is there anywhere I can read up on all that? I'm trying to look it up myself but haven't had much luck

[proud mauve]

Is it possbile to change the Camera sensor width/height in runtime? maybe with a slider widget? UE 4.27

[gentle urchin]

Camera sensor?

[proud mauve]

these

[gentle urchin]

Guess ypu gotta chevknifkits exposed

Search for related nodes

Set filmback / sensor something

[lethal pollen]

Hi! Where do these arrows come from? This blueprint class inherits from a C++ class, but I haven't define them on it. Thanks!

[proud mauve]

Thank you 🙏😃

[thin panther]

Not really, most people are unaware, and Epic really like to pretend a lot of things aren't broken

[rich ferry]

Ah rip. Thanks though.

[floral totem]

Wow thanks for sharing, I’ve been listening to math videos all day at work trying to get what I need lol

Thanks for sharing! I will look into this!

[fossil crystal]

If using a square grid in a 1000x1000 . Will increasing square size or reducing the square size have any performance issues? Lets say each square is an actor

[lofty rapids]

i would think so

the more you have, the more calculations

[young meteor]

I'm trying to get a bunch of actors with "Get all actors of class" and check if they are disabled.
I could do this with a simple Boolean, but then I have to cast to every single one on every frame.
Is it cheaper to do an "Actor Has Tag" node and then a branch based on that instead?

[faint pasture]

at what level are they disabled?

what does disabled mean

[young meteor]

It means nothing code-wise at the moment. Just need a way in the game to check if they have already been "eliminated" and are therefore disabled (gameplay-wise)

[faint pasture]

I'd maybe first check if there's some sort of bool in Actor you can piggyback on

Otherwise I'd use a tag yeah, unless there's a very obvious base class that a bool can live in.

[young meteor]

Not sure what you mean. Different from my own code you mean?
Right now I just set a Bool like this, but I have to do casts to check it from another actor.

[lofty rapids]

wdym you have to cast to every single one, you probably want to avoid get all actors of class on tick, will they be changing ? because you could cache them on something like begin play

[young meteor]

I'm basically trying to avoid too much casting. Don't know if Tag check is actually cheaper though.

[young meteor]

Hmm, good point. They will be changing but I could update the Actor calling them in that case.

[lofty rapids]

since casting can be heavy, i have not heard that actor has tag is like that, so i would probably go with has tag if you can

[young meteor]

Still need to get each one to do some math though.

It's a tower defense, so trying to get all towers and define the closest target to shoot at.

[faint pasture]

All towers sounds like a base class

if you get actors of class TowerBase then you can just get the thing, no casting

[young meteor]

They all share a template yes.

[faint pasture]

casting is basically free but it does imply the class being loaded, and seeing a ton of casts as checks all over the place is indicitive of a bad design

[young meteor]

children of it

[faint pasture]

K so get that class and put the functionality in that class

What's the rule? A given tower shoots at.... what?

[lofty rapids]

so your looping through the targets, but why not just use location instead of casting ?

[young meteor]

Not sure what you mean. There might be 10 towers, but 3 of them disabled (don't know which pre-gameplay)

[faint pasture]

What is the actual mechanic? You're trying to have the enemy choose the tower to shoot at or what?

[lofty rapids]

i would go wit has tag if you can

[young meteor]

Because I don't want to set my Actor to shoot at the tower if it is already Disabled.

Or do I misunderstand?

[young meteor]

Correct

[lofty rapids]

ya that makes sense your check in the loop if it's disabled ?

[faint pasture]

Timer -> get actors of class BaseTowerClass -> select closest where BaseTower.bDisabled = false
No casting involved

[lofty rapids]

what if you made the variable a reference to the tower so you didn't even have to cast

i'm guessing now it's an actor or something ?

or there will be other actors of different types in what your looping ?

[faint pasture]

Although if you have a lot of enemies or towers around it'll be way more efficient to have some other query mechanism eventually

[young meteor]

Thought a sphere trace would be more expensive because it had to calculate geometry. Might be a bad assumption though.
Is there a select closest function, or do you just mean I write my own?

[faint pasture]

I thought there was a sphere trace by class but there isn't. Get actors of class is fine if there's not a billion of them

[young meteor]

Guessing 50-100 tops in actual gameplay.

[faint pasture]

I'd probably make some sort of manager thing

But don't do that until you need to

[young meteor]

Not sure what you mean. Both enemy and tower is an Actor yes.
No other actors, but I have a function pretty much identical for tower vs. enemy instead.

[lofty rapids]

i mean what your casting to, what is the array full of, it's towers right ?

[faint pasture]

Get actors of class YourBaseTowerClass, that'll be a simple lookup

you don't have to cast, you'll know it's a YourBaseTowerClass.
You'd only have to cast if you got actors of class Actor

[young meteor]

Yes

[lofty rapids]

and the towers will always be the same or you will have many different ones that you may need to cast to ?

if they are the same just set the variable to be that class instead of actor

[young meteor]

Already do. This is what you mean right?
Actually use sphere overlap lol. Thought it was an All Actors Of Class node 😄

[lofty rapids]

oh ok, so you couldn't do what i was thinking because of the way your getting the towers

[faint pasture]

That wont return an array of that type I don't think, what type does it return?

[young meteor]

But I need to cast to know if that Boolean "Disabled?" is true or false right? Or can I check some other way?

[faint pasture]

if you get actors of class YourBaseClass you won't need to cast

you'll have access to everything in YourBaseClass

[young meteor]

Not sure if this is what you mean? WorldDynamic?

[faint pasture]

ignore the trace, do get actors of class for now

[civic tree]

hey guys, i am having a very basic graphic settings setup, and during our playtest for our game, some testers reported crashes when changing from low to high or the other way around. these are the settings, as you can tell the very basic setup:
We are running ue 5.3.2, any idea why the game could crash?

[lofty rapids]

are you just trying to get the closest one ? a trace probably not the way to do that

[civic tree]

the bug report is not really helpful either, just some random render thread error

[young meteor]

Think I still need a cast to get the Boolean

[young meteor]

Yes

Sorry no.

Only in this case.

[faint pasture]

what type is that OutActors?

[young meteor]

Have different targeting methods. Highest health, Furthest along path etc. But I switch on an Enum earlier and have a separate execution path for those.

[lofty rapids]

maybe remake the for each

it's probably still the other type

drag out from out actors and do foreach

might fix it

[young meteor]

Bingo ^^

So you guys would guess this is the cheaper way instead of the Sphere overlap to search in it's X radius?
Considering we are talking 50-100 ish Actors?

[lofty rapids]

oh i c you did a sphere, that would probably be much cheaper i would guess

blueprints is horrible at looping

[young meteor]

Sphere required a cast though. Unless a Tag check does not need such.

[lofty rapids]

i feel like if you can get away with just checking the tag then that might be the most efficient

considering you use a range with that sphere so your looping through a lot less which is a big difference

from what i've learned when looping in bp you want to keep it low as possible

especially if you added even more say 1000

then it would be bad because bp wants to do these in one tick and has issues with it

[young meteor]

Then I'm back to the original line of though, and I forgot how to add a simple Tag 😄
Is this the right node? And I would have to create a container?

(not for checking the tag, but for adding the actual tag on the tower)

[lofty rapids]

idk i have not used tags yet

[young meteor]

Alright.

[lofty rapids]

thats why i said if you can do it i'm not even sure if it would work, but it makes sense you just check the actor has a tag as far as under the hood i bet it's not much going on

[faint pasture]

Depends

The more spread out they are relative to the sphere radius, the more efficient the sphere trace is. But then you'll need to do the casting etc. It's probably faster to just get all of class up to some number.

[young meteor]

I'll learn Unreal Insights later I guess 😄

[rich ferry]

Is there any way to get this into here?

[faint pasture]

Not really, but you can iterate over that map in the construction script

[rich ferry]

Damn. I'll see what I can do.

[remote silo]

i cant figure out why my gun isnt going to my mesh my character, everything seems to be going correctly except no gun apears in my hand.

[lofty rapids]

so what does it print ?

[faint pasture]

You're destroying it immedietly

[remote silo]

When i overlap it casts to my character, and when i interact with it it destroys actor, and sayd its supposed to work

[faint pasture]

It goes to your hand, then deletes self from existance

[remote silo]

even if i remove my destory actor, it does nothing

[faint pasture]

put breakpoints in, where does it fail?

[steady night]

hey

how can i clamp so the valu cannot be -20 = +20

so min wouyld be -70-20 and max +20-+70

[lofty rapids]

i'm not understanding what your trying to do

[steady night]

i mean something like this i suppose

[rich ferry]

Any way to reorder these?

[steady night]

https://gyazo.com/d9b88572e6f678af60c5d3f3c360cefe

@lofty rapids

the problem im having is when im walking backwards the direction is not 0

[faint pasture]

uh

what

what are you actually trying to calculate?

what do -20 and -70 mean

[steady night]

scratch that

my laster question is the objective

when i walk backwards i dont get 0 in direction

[rich ferry]

This?

[steady night]

this is how im getting the cdirection

[lofty rapids]

it looks like you get positive going forward, negative going backward ?

you want it to be zero going backward ?

just clamp it 0 to max

[steady night]

the problem is when im walking backwards i still want -70/+70 in direction since u walk in that direction backwards

but when im only walking straight back i want it to be 0

now its choosing whatever is closest

[faint pasture]

what is cdirection?

[steady night]

Direction*

[faint pasture]

70 and -70 are both forwards

90 is right

180 is backwards

as is -180

[steady night]

yeah

[faint pasture]

so why are you clamping to 70

[steady night]

for my BS 70 is enough dont need 90 *

that works fine

[faint pasture]

change your blendspace to map right to 90

your blendspace should go like this

Back Left Forward Right Back
-180 -90 0 90 180

[steady night]

yeah thats fine, but still when walking back im getting 180/-180

yeah thats the problem

[faint pasture]

well yeah, that's what it is

set up your blend space to just accept the actual angles, that's easy

[remote silo]

sorry im still new to this, had to figure out how to use breakpoints

[faint pasture]

put a breakpoint on the node it should be hitting

if it doesnt hit, move it up

until it does hit

the node you care about, presumably the attachment

[lofty rapids]

it looks like the nodes firing

[fading hawk]

This might be a silly question, but :: I have MyPlayerController_Child and MyPlayerController_Parent BP classes. Naturally the Child uses the Parent as parent class. Now is it possible to get a variable from the Child in the Parent class?

[rich ferry]

I'm trying to get my BP components in a specific order but they keep spontaneously reordering themselves???? What the hell.

[fading hawk]

Why is the order of the components important? (I'm just curious)

[desert flame]

Hey, more of a math question here.

So ive got this segmented bar system (like the HP in Overwatch). It spawns a bunch of progress bars in a horizontal box and changes the values of each progress bar for the total health value.

And with these values it works 100% perfectly to the correct pixel of health. But if i change how much is in 1 segment (automatically reducing the amount of segments), it all just breaks. Some segments just copying others, some just not working etc.

Red numbers are the numbers inside the nodes.

[rich ferry]

I am mapping them to the name of the socket they need to use, so I need to have them in the same order as the keys in the map. I can't preload them into the map either unfortunately.

[fading hawk]

Can't you map them by class or by name instead of possitional index?

[rich ferry]

I'm fetching the components into an array, I just want that to slide into the map I have instead of having a second map or a bunch of ifs to figure out where they go. This wouldn't be difficult if it would just let me reorder them!

Or better yet let me preload them into the map

[fading hawk]

Gotcha - I mean it makes sense - but I think the components list is an unordered list and just gets sorted for display purposes.

[rich ferry]

Sorted dumbly, that's for sure. No rhyme or reason to it.

Also my editor randomly froze so that's fun

wow yeah this is fucking dumb. Idk what I'll do here but I'll figure it out later lmao

[cerulean stone]

hi! is there any way to set initial value of my camera to black (alpha 1)
in blueprints
because i have an issue when connecting to remote server, there is a period where the camera is transparent (alpha 0)
it seems like this default camera is initialized before everything else

[foggy escarp]

I've been trying to set up my actor class to be queried by the asset registry without much luck. I have the asset manager set up and the asset is viewable in the asset audit. The manager is successfully retrieving the assets. I am intending to set this up with a library in C++ and noticed the issue in testing the function I created.
I thought that if things are correctly set up with the asset manager then surely the asset registry should be able to retrieve them.

I'm not really sure where this could go wrong if the asset registry can't return the assets, but this is working

[mortal coral]

Having a weird issue with saving Project Settings; whenever I reload my project, the Action Tags in my Common UI Input Settings are set to None. The rest of the settings are still there, it's just the tags that are gone

[pastel skiff]

hey so i want to throw a granade right, the granade is a projectile movment, but the i cant figure out how to make it so that liner velocity poits in the direstion where me character is facing twords, any help?

[foggy escarp]

You could instead set the rotation of the projectile to face the velocity direction of itself on the tick event.

[pastel skiff]

how?

[foggy escarp]

Wait do you mean the rotation of the projectile or fire in the right direction?

[coarse condor]

I cannot figure out event dispatchers to save my life. Separately these two blueprints work but I just can't seem to get them to communicate with each other no matter how many guides I watch.

[pastel skiff]

i want the projectile to shoot in the direction of me camera

so i want me velocity to face the way me camera is facing

[lofty rapids]

is the cast succeeding ? and is counter the image on the left ?

[coarse condor]

Yes, counter is the image on the left. How would I know it's succeeding?

[lofty rapids]

print string out of succeed and fail, see which one it shows

[foggy escarp]

When the projectile is spawned though your weapon or on the input key, just spawn it with the correct angle to face forward. You can do that like this:

[coarse condor]

If I put "Confettipop" into a print string nothing happens

At the end of the bind that is

like this I'm assuming?

[lofty rapids]

see how cast has two paths ?

succeeded out the top, cast failed just below it

[coarse condor]

oh

[lofty rapids]

put a print string out of of cast failed i'm guessing it's failing

[coarse condor]

Okay yeah it's failing

[lofty rapids]

what is count ?

i c it's a variable ?

but where do you set it ?

[coarse condor]

well every time I try to look up anything about casting it only ever uses default blueprints and object is usually "get player character" but counter is just an actor blueprint, so I made an actor variable and slapped it in

which I'm guessing is wrong

[foggy escarp]

Something I wish I did earlier on was enable the feature break on exception. This forces you to handle access nones if you have them and it allows you to see why something may not work way faster. Sometimes it can be a pain though and it can simply be turned on/off whenever.

[pastel skiff]

so i got this and nope it doesnt work

[lofty rapids]

well it's have right, but since your doing it on begin play you could probably do get actor of class. I'm guessing you made the variable but didn't actually set the value.

[foggy escarp]

your begin play for the projectile needs a velocity in the relative rotation of x not y

[coarse condor]

I just set it as an actor reference

I could try get actor of class.

[pastel skiff]

nope still the same

[lofty rapids]

ya so when you do that, it's just an empty variable you have to actually set it to something

[foggy escarp]

the projectile movement component should be doing this for you and not a velocity

[coarse condor]

I'm assuming I did it wrong again, but this also did not work. Is there an example of something I should be setting it too? Should I be grabbing something from my counter blueprint?

[lofty rapids]

see where it says actor class ? click the dopdown and pick the counter class your trying to cast to, then get rid of the cast and set the variable to the return value of get actor of class

[pastel skiff]

what do you mean?

when i remove the vlocity it stil does not work

[coarse condor]

it worked, thank you so, so much

[dark sparrow]

Hey all, pretty new to working with unreal BPs here, trying to recreate a LUA mod I made in BPs. I'm a little lost on how structs work in unreal and was hoping I could get some pointers.

Effectively what I'm trying to do is watch for a new item container to spawn and when it does, compare the item inside with all other item containers, given that every container has exactly one item inside. I was able to make this work using an array of containers, but I was hoping to speed the process up by adopting the same approach I took in LUA - making a map of item type:container so that when I get a new item, I iterate through only containers with the same kind of item inside rather than wasting time iterating over all containers that exist.

I made a struct that holds an array of containers, and a map of item type:struct, but for some reason I can't seem to add a new container to the array - once it's made, it's made

[sage lagoon]

I have yet another question. Let's say that I have a game that sends the player from the first gameplay map to another just for a dialogue cutscene. Then, the player is sent back to the first map after the cutscene is over, but I want to send both the player character and the FollowCamera to a different location once the map is loaded and a Boolean that has been turned on causes the map to load at that different location instead of its default starting point. How would I go about doing this while ensuring the camera is focused on the player and not outside and somewhere in the skybox?

[dark sparrow]

I get the array using map -> find -> break struct, then add to it using the array add function. When that didn't work, I figured maybe it's passing me a copy of the array rather than the array itself, so I tried array add -> make struct -> map add but that doesn't seem to work either

[kind estuary]

can i use a Pawn that has inputs to be controlled by the AI?

Or its best if the pawn has no inputs at all if its an AI pawn?

Asking in case there is some underlying issue...

So far it seems the inputs are disabled

these inputs

[lofty rapids]

why you want inputs on the ai ?

you want to control it ?

[kind estuary]

i dont want them

[kind estuary]

its just that the pawn logic and functions is the same as for the human player

so im using the same pawn class

and see no reason why i need a different one

should i create a different one?

the only difference for now is just these 3 inputs that are not enabled it seems

so isnt it ok?

[lofty rapids]

i don't know whats right or wrong, i would imagine as long as its not duplicating the input presses you'll be fine

[kind estuary]

exactly

[kind estuary]

though ur not sure?

[lofty rapids]

no i'm still learning, but just logically you should be ok

[verbal nova]

Whats good fam

[hexed cloak]

Yes you can use the same pawn without issue. What is the issue you're having with the pawn?

[quiet token]

Could anyone please explain to me how i could make the green spots that i have on the texture more opaque? i mean kinda transparent? I can decide how much green spots i want from the noise, but not the opacity

[lofty rapids]

there is also #materials

[quiet token]

oh sorry, tought since its blueprint i'm right here. i'll try that thanks for mentioning

[pale imp]

is there a way to duplicate an already existing actor through blueprints ? I've made 2 enemies and so now I want to make an actor which handles spawning them

[kind estuary]

for now none. just asking in case in the future i get a surprise

thanks

[lofty rapids]

you want to spawn actor ?

[pale imp]

Duplicate an already existing one in the world

[lofty rapids]

from what i gather online you can do it in c++

but bp not so much

[thin panther]

A common misconception :P
Blueprints aren't materials. Blueprints are strictly the nodes you use in things like actors.
The material graph follows a completely different set of logic, and way of thinking. Even though it's still using nodes that look similar, it's wildly different

[undone bluff]

you can just grab the relevant properties and apply them to the newly spawned actor, it's probably not that many

is the duplication some sort of game mechanic

[lunar sleet]

Idk about “duplicating” but you can get class and spawn another

[spark cliff]

hey all, something about the factory first person blueprint eludes me.
it has IA_Move, IA_Look etc, thus uses advanced input action mappings, but the blueprint graph makes no reference to loading it? this seems more elegant, i'd like to know how this is being assigned the IMC without having it in the node graph:

oh nvm, just found it, for reference for others, its attached via game mode blueprint, 'BP_FirstPersonPlayerController' has the Enhanced Input Local Player Subsystem code within that

[undone bluff]

for the record, that is what the player controller is for and if you had a more complex setup you'd have your input actions in the controller and pass them to the character as appropriate

[chrome pumice]

Quick question, i wanted to make that the player gets a random item from this array every 10 levels. The "unused" stands for "unlocked" and basicly it should unlock an item that isnt unlocked, if it gets an unlocked one, it should try to get another, i have many instances where i just get no item at all, any ideas?

its pretty simple code i just have massive brain lag i think

it worked for a while then randomly stopped giving me items on lv 20 for some reason and now its completly fked

[valid solstice]

Does anyone know how to add a stamina system where everytime I dash it takes a chunk out of my stamina and when I dont dash Aka just walking and running around it recharges this is my Dash BP

[wraith loom]

Could you perhaps make a seperate array to track what can still be chosen every 10 lvls?

[chrome pumice]

yea good idea actually

ty

❤️

[wraith loom]

Well you could just make it so that you regain stamina every tick and remove stamina after a dash

[valid solstice]

Could you explain how to do it?

[wraith loom]

Ok well have an Event tick node that adds an amount to a integer Stamina variable. Make sure to multiply that amount by delta time, so that the regeneration doesn't depend on framerate. Then at the end of that dash code you have just remove a certain amount from the Stamina variable.

[distant hollow]

Might anyone have a clue?

[iron heron]

Does Blueprint support condition break for debugging?

[sage lagoon]

What would be the best way to, say, teleport the player when a level is reloaded? More specifically, I move the player back and forth between two maps. But, after setting a Boolean variable to "true" on the second map after a cutscene is over, I want to reload the first level and place the player character in an alternate location, using a trigger box that moves during a level sequence and works when the GameMode's Boolean is True. Like so:

https://blueprintue.com/blueprint/ldb1eafd/

So, what is the best way to send the player to a different location when the level is reloaded and under special condition(s)?

[valid solstice]

Anyone know where I should put my stamina in there I already have an Increase and decrease stamina I just dont know where to I put it I also want it where you have 0 stamina you cant dash animation

[limber parcel]

does it happen only in editor or also in shipping build?

[twin shale]

I have a blueprint with a editor callable function that just adds a Instanced Static Mesh Component to the actor and adds some instances. Really simple. Whenever I drag the actor and the constructor runs, it deletes the instanced static mesh component and clears out all the meshes. Is there a way to run this in the editor and stop it from deleting the Instanced Static Mesh component?

[limber parcel]

uhh not really, you have to save the stuff u want to keep

[twin shale]

Is the only way to do this to convert this to a mesh or something?

It's literally just a blueprint that's intended to throw junk on the floor and dirty up spaces

[limber parcel]

create a save object and load data from there on construct

[twin shale]

Boy. Okay. I don't love that but I guess I can do that easy enough

[distant hollow]

Haven’t tried shipping build

[limber parcel]

normally lighting bugs like that only happen in editor

[distant hollow]

I think it’s not just lighting, but the door itself is flat

But I’ll test out shipping build

[valid solstice]

Do you know how to do this
Anyone know where I should put my stamina in there I already have an Increase and decrease stamina I just dont know where to I put it I also want it where you have 0 stamina you cant dash animation

[limber parcel]

why are u changing the actor scale instead of just moving it?

[limber parcel]

do i look like chatGPT who teaches basics of coding???

[distant hollow]

Move? I need to mirror it, wouldn’t reversing the scale be the correct way to do it?

[limber parcel]

i dont think thats how u mirror stuff in unreal, there should be a mirror option for that

[fervent rune]

need some help, I currently have a feature in my game to be able to zoom in like a camera, it's working but now the problem is players can spam the zoom button and it will zoom in and out when ever it is pressed, I want the the player to be able too zoom again when it's finished zooming out or in

[distant hollow]

I don’t find such a function for runtime

[limber parcel]

yeah cant find one either, guess the issue is just shaders not updating properly in editor

[limber parcel]

add a branch with a bool at start of your code, set the bool to true at start and false when your timer finished

and make your code run only when bool is false

[fervent rune]

hmm I don't really get it, can you explain it more detail please ?

[limber parcel]

i literally cant

[buoyant moat]

Given I have the projected screen coords of the yellow reticle. Is it possible (and if so how can I achieve it) to define some kind of mask on the screen such that any pixel inside of the grey reticle return true and the ones outside false.

I want to define zone in the hud and reason about them for the gameplay and they might have intricate shapes more complex than a simple circle

Essentially trying to answer the question: Is the projected screenspace position of a given target inside one of those zones

[limber parcel]

https://gist.github.com/whoo24/09324dcff276e0247f18fd12005ebcfb

[buoyant moat]

I have no problem getting the actor screen position. The issue is trying to define complex regions (through some sort of masking I guess)

[limber parcel]

yeah u will probably want to set up a system with custom widgets based off that

[limber parcel]

maybe this helps
https://docs.unrealengine.com/5.3/en-US/API/Runtime/Engine/FGeomTools2D/IsPointInPolygon/

[sage lagoon]

Can anyone help me with this, please?

[undone bluff]

ahhh it took me multiple hours to figure this out the other day, where was this when I needed it

[limber parcel]

you can use GameInstance, it persists when loading new level

[limber parcel]

either game instance, or you use the save system

[sage lagoon]

I forgot all about GameInstance! I'll give that a shot.

[iron furnace]

Does anyone know how to fix messy lighting? This is a new map with all new directional light, sky light, etc, and yet if i set directional light to .1, it just slowly goes from dark to light over a couple seconds. Im just trying to make a night map and have watched videos, etc, yet dont see anyone else with this problem. Any help?

[sage lagoon]

Oh right. I forgot.

https://blueprintue.com/blueprint/fo7ojtu2/

I did try using breakpoints here, but the program just stopped at "Set Target" for MyGameInstance and didn't go any further.

[lunar sleet]

Probably #lighting people

[limber parcel]

you need to add a post process volume and change the exposure settings

[iron furnace]

Thanks, there wasnt any in the map, so that probably explains it. any suggestions on exposure settings, or just mess around with it till it works?

[limber parcel]

you can just set it to manual and change the exposure compensation

[sage lagoon]

It might be a good idea to play around with the intensity and the radius, too, maybe.

As well as color if you want, say, a full moon light.

[limber parcel]

you can also add a slightly blue tint in the PPV for nighttime scenes

[sage lagoon]

And, of course, you can try looking for a night sky skybox. There are some free ones, out there. Just to make the illusion more convincing, anyway. That's just a suggestion.

You could also play around with the different types of lights UE has to offer.

[limber parcel]

and add volumetric fog

[sage lagoon]

I think a Directional Light would work best, if you want an outdoor ambient light.

[iron furnace]

ill be looking into all of that, thanks for mentioning it. Im trying to go for an abandoned town fogged up, getting attacked by monsters from the thing. I have some lighting on the indoor portions of the map, but i just wanted something a lil freaky going on when the player steps outside

[sage lagoon]

Good luck!

[sage lagoon]

Can anyone explain why the program seems to stop at the variable setting node?

[limber parcel]

probably because ur cast fails?

[sage lagoon]

Which is odd because I didn't get any notices of cast failures.

[limber parcel]

just add a print on cast failed

[sage lagoon]

You mean, like, a print string before and after the Set Boolean node?

[sage lagoon]

Oh! So this is in case the cast fails?

I always wondered what that connecting point was for.

[limber parcel]

https://tenor.com/view/stare-disappointed-homer-scowl-gif-18593309

[sage lagoon]

I'm still relatively new.

Excuse me.

[obtuse mulch]

its sometimes useful

[gentle urchin]

Its very usefull to get in the habbit of adding prints where things can silently fail

It also helps to be descriptive in the printn

Often including class/event name aswell

[sage lagoon]

Now this has happened:

After linking Cast Failed to the Set Boolean node.

[gentle urchin]

Show code

[sage lagoon]

https://blueprintue.com/blueprint/fo7ojtu2/

[gentle urchin]

Cast failed means the incoming reference is not of the underlying type you're trying to cast to

Cast fails means you cant access the reference provided by the cast

[sage lagoon]

When I try to connect the usual way like in the above code, the program just stops at the Set Boolean node. Which is why I changed that to Cast Failed on a suggestion I was given.

[obtuse mulch]

error says that ur Asmygameinstance variable is empty

you dont set it anywhere

[gentle urchin]

^

[sage lagoon]

That's odd. I did declare a variable. I thought the GameInstance never reset its settings.

[gentle urchin]

The suggestion wasnt to execute logic on the failed cast reference

But to add a print string

Which is something completely different

[sage lagoon]

Oh. Sorry. It's late at night over here.

So should I just put in a Print String before and after the casting?

[gentle urchin]

No need as we know the issue

Atleast, you dont shownthat you've updated the variable , and the cast fails

So

A variable is , as you might know, just a container for something

[obtuse mulch]

you must set the gameinstance variable in that particular bp

[sage lagoon]

Which would be a level BP, in this case.

[gentle urchin]

A reference variable can hold a reference to something, but is by default nothing

[obtuse mulch]

and you must do it b4 the function

before ur actor overlap event shoots

[gentle urchin]

Or use GetGameInstance as the input to the cast

[sage lagoon]

Hm...as opposed to promoting to a variable which I did?

[obtuse mulch]

when?:)

[sage lagoon]

Like if I did this?

[obtuse mulch]

ye thats good

[sage lagoon]

I just tested, but I get the same error after test-running it and stopping it.

There must be something else I need to do before this.

[obtuse mulch]

did you set the gameinstance in project settings?

maps and modes

[sage lagoon]

I think I found it.

Okay, I've changed it to MyGameInstance.

[frosty heron]

call it BP_MyGameInstance for better readability

[sage lagoon]

Okay.

Very peculiar.

https://blueprintue.com/blueprint/8253h91v/

Here, the game is supposed to teleport the player once a cutscene has ended and the Boolean is set to "True." But for some reason, it acts as though the Boolean under MyGameInstance is still False.

[obtuse mulch]

did you check with print string that it goes all the way to false?

thats some strange code right there

why do this

[sage lagoon]

Oh right. It was originally because of a TriggerBox that would move when cued. I just forgot to remove that.

So I've set alternate Print Strings based on the Boolean when the level is loaded, and the Boolean is false.

But...I need to get some sleep. I'll work more on this tomorrow. Thanks for the help so far. Good night for now.

[sick sky]

should i avoid saving cast references, and just do interfaces most of the time ?

[limber parcel]

ure not supposed to link it to that node

[obtuse mulch]

avoid saving them yes

startup times wise

but i found out if you save them in their parent class variable, then just cast again everytime when you need it, it works

never bothered using interfaces

[gentle urchin]

whats being cast and why should be some fundamental questions before answering

Casting is fine in many cases

saving a cast reference or not doesnt matter much as the cast already creates a hard pointer to the thing you're casting to

[sick sky]

well for example
in my player state, i am updating UI

so on BeginPlay I wanted to update the UI, by getting the HUD class (widgets are saved there) and save it

i finally made a interface, because this event could be later on called outside of the playerstate

[gentle urchin]

Why is the playerstate updating the UI would be my first question

[sick sky]

well, where should i put it ?

[gentle urchin]

UI should update itself based on data from the thing they represent

typically one gets that done through event delegates

[sick sky]

• the gamestate updates player data
• player state is changed
• UI needs to be updated (and rn its updated from the player state, because it seemds more logic than doing this in the game state)

[gentle urchin]

create a delegate in the player state

"OnDataChanged" (to be very generic)

[sick sky]

i am using delegates

• the gamestate doing stuff, calls delagate
• the HUD class has a ref from the game state, and assigned events from those delegates
• the delegates call specific widget functions

there is just this example where its not the same, maybe i should do the same architecture

[gentle urchin]

Let the objects handle them self , as much as possible

letting other classes update an unrelated class becomes messy very fast

[sick sky]

okay

so i should have my widget assign the game state delegates ?

[gentle urchin]

bind to them, yeah

[sick sky]

i first wanted to put in it HUD so i can have 1 place to store the game state ref
instead of having this game state ref in each widget

[hollow bane]

Hi I have a question:

I have an enemy actor bp. Now if this actor is hit by a line trace the next level gets streamed in.
In the next levels i have multiple copies of this enemy bp in my levels. i have already gave them tags.
How do i make the level load once all of the enemies were hit and not only if any of them was hit?

[gentle urchin]

you'd probably want some manager that checks this, and listens for delegates from the enemy actors

[hollow bane]

so what kind of message does my enemy need to call?

[gentle urchin]

depends

are you waiting for their deaths?

or is this a ray of light just aiming at them ?

[hollow bane]

hmm not quite sure, basically just if they get hit by the line trace thats enough for me to send a message "i was hit"

[gentle urchin]

right

[hollow bane]

now i need them to count themselves somehow

[gentle urchin]

so you'd want some custom event dispatcher

with a bool

RelayHit(bool bWasHit)

then you just call that whenever you're hit / not hit

[hollow bane]

so from my event dispatcher that is coming from the linetrace bp i need also a condition

but how do i make them count if all of the enmies were hit or not to trigger

[gentle urchin]

thats the manager part

[hollow bane]

thats my current call i send when something is hit

[gentle urchin]

in my prototype i made the manager spawn in the enemies

[hollow bane]

this is how i make sure that only the enemy that was hit adds up to the score

[hollow bane]

the enemies in my case are actually obstacles that are there from the beginning of the level

[gentle urchin]

specificly listening for a delegate (RelayHit would be yours)

Well the manager can just "GetAllActorsOfClass"

[hollow bane]

oh i see

nice

let me try

!

[gentle urchin]

then this manager deals with the "completed" condition aswell

I'd say this is a bit hacky, but it shouldnt cause any trouble really

[distant hollow]

Tested on shipping build, apparently same issue

Hiaz

[sick sky]

would this work ?
im trying to find another way to reference events

sometimes i got a "unbind" that is somewhere else in the graph, and i have a red line crossing half of the graph

[thin panther]

Yes, that's what that node is for

Also works for functions

[sick sky]

does it change performance ?

[thin panther]

Possibly my favourite node in unreal

[thin panther]

No, you don't worry about perf at that level in BP anyway

[sick sky]

in what case do you use this for functions ?

curious

[thin panther]

You gain orders of magnitude more performance by using C++, so not a worry

[thin panther]

The same case as above, if you didn't want it on the event graph. Or if you wanted to bind an overriden function.

I mostly use it on a set timer by event though, as you're unlikely to need latent actions in the callback on those

[sick sky]

okay ty

interesting

[fervent rune]

I got it fix by using Do once node, thx

[timber basalt]

hey all i wanna ask is there a way to target a specific collision of my enemy (testing dummy)

[gentle urchin]

GetComponentWithTag ?

[wild crater]

How does the editor infinite loop detection work? I know it can be nested loops. But could it also be a series of manual calls on a function with a loop?

[thin panther]

Basically, if iterations in the frame in a single function is over X amount, throw error

[sonic arrow]

I just love yandere dev spaghetti code V2

theres only going to be 2 recoil patterns but up to ~10 guns

so either the spaghetti code will largen, or I will have to figure out how to properly implement guns, im dumb and dont know how to follow instructions so its a wee bit hard

[wild crater]

Okay so if a function containing a loop is called multiple times (not from another loop) and that's the reason it exceeds the limit, it would not throw an error?

[thin panther]

It shouldn't, no

But who knows, it could be total iterations per frame.

I don't believe it is though

[gentle urchin]

Total execs*

Is the count

[thin panther]

Either way, keep heavy iteration out of blueprints, it's incredibly bad at it

[gentle urchin]

So a loop of 100 with 3 function calls is 300+

Along with the internal in the loop macro

It hits the limit far sooner than actual iterations

[thin panther]

Woohoo! Go BPVM!

[gentle urchin]

Frameslicing is a trick if you really need it in BP

With it you can go quite high... it just takes time. Lots of time

[thin panther]

"Sorry we know it's been 3 hours and the game hasn't loaded, but we needed to frameslice the BP only quantum computing"

[gentle urchin]

🤣

Frozen loading bar the entire time

[thin panther]

In all seriousness though, frame slicing is amazing for some things.

[thin panther]

https://tenor.com/view/loading-loading-bar-blender-processing-gif-17914411

[wild crater]

really? how do you know this?

[sonic arrow]

thanks for the tutorial

[wild crater]

Another infinite loop question: When the log says "see log for stack trace", does it mean some other log I'm unaware of? As this is stated in the output log

[thin panther]

Perhaps the message log

Or the log file.

[wild crater]

log file seems to contain the same stuff

can the message log be seen as a text file?

[obtuse mulch]

window > output log

[fleet cedar]

Hello.

I want to play a cinematic and then set a bunch of variables when it finishes across various blueprints (visibility, actor locations) - should I do this in a particular BP? Level BP maybe?

[thin panther]

No

The message log is what gives you your "accessed none" errors on ending pkay

It also normally lets you jump to where your infinite loop is

[frosty heron]

deffinitly not level bp

bind the sequencer End Event, you can do your business there

[lime basin]

okay what im doing wrong here?

since I'm hitting myself 😄

the collision settings is of the sword blueprint that is child of player

[gentle urchin]

Try adding self to actor to ignore

[lime basin]

i did still the same

[versed sun]

Try adding Get Player Character to Ignore

[pure rain]

Looks like the event is not being updated, your only firing the event once

So it only account for the initial location? Could be wrong

[lime basin]

still the same :/

[lime basin]

even gets fired everytime i press mouse input

but its tracing only once

[versed sun]

add a ref to whatever BP has the character mesh to the ignore

[gentle urchin]

Print display name of hit

Hit actor and hit component

[lime basin]

good idea let me see

not printing anything

[gentle urchin]

.......

U didnt connect the execute

[lime basin]

oh lol

one sec

[wild crater]

question about pure nodes: seems like they get executed regardless of whether its return value is tied to the true branch? Do they just get executed always regardless of the execution flow?

[gentle urchin]

Example?

[gentle urchin]

Add the sword to the ignore list

[wild crater]

ah wait I think I've found the culprit, it's a select node probably

[gentle urchin]

Yes

They execute all connected logic

[wild crater]

👍

[gentle urchin]

Regardless of the select value

[lime basin]

yep that works now i just need it not to ignore other enemy pawns xD

but i can do that myself thank you 🙂

fixed it yay

[spring rose]

Is there a simple and easy way to do this?

[spring rose]

I'm new, so just for clarification is this two different ways to achieve the same thing? 🙂 Both look very reasonable and i'll have a play with them. The top one looks interesting, is "list of set classes" a thing or is that a variable or something you've named and I need to make that node myself first? 🙂

[versed sun]

its an array of Classes

and yes, 2 different ways

[spring rose]

I had wondered if an array would be used for it. Something I haven't touched on yet.

With the option at the bottom, the one that is easy to read and grasp to me, is there a way I can make one of the options have a lower chance to occur or do we complicate the selection process and I won't touch that kind of cutomization for now?

[versed sun]

if there is only 2 options , you can use Random Bool with Weight

[spring rose]

If i wanted more than 2?

I appreciate the help you've provided btw. Definitely cool to know that there's an option I understand that will change up what i'm doing just a bit to add a little bit of flavor 🙂

[versed sun]

you can chain them together

or , in the array , add more of 1 item fro more %chance to pick that one

[spring rose]

I see!

[spring rose]

And the weight is basically in your imagine above, 50%, 33%, 10%?

In theory or

[versed sun]

yah

[spring rose]

So if it were 1.0, it basically wouldn't work because it'd always be selected right

It wouldn't make any sense to use it in that way, basically

[versed sun]

yes , 1 is True, 0 is false, anything between is %chance

[spring rose]

AH

Ok, that clicks. Gotcha

Ohhh yes, right i get it, random bool with weight. Right right right, that makes sense.

[versed sun]

most things like that have a tooltip

[spring rose]

Very helpful to know.I've got to know the node exists and does something like what i'm after but that'll certainly help me remember in future when i look at the nodes again.

I may have bitten off more than i could chew haha. It was a cool idea that i'll probably be able ot get into later. I guess I didn't fully understand what the static mesh part was doing so I don't know how to problem solve this one.

[spark steppe]

either all classes have to inherit the same base class which provides a static mesh component

or you have to use get component by class on the resulting actor, and eventually have checks in place since it may not exist

[sick sky]

im having a hard time to find a perfect "formula" to make my directional light rotate (and make it fit the time) to make a day/night cycle

in my game state i am counting a fake time (hours & minutes)

• i would like my directional light to have X rotation at 22:00 (start of "night")
• and have a Y rotation at 6:00 (start of "day")
• then rotate back to X
• and so on

so the first problem is : finding the good way to rotate it to lerp correctly between X and Y

the second problem is, the solution of the first problem needs to have a implementation of "speed", because if all players sleep at night, the count of the fake timer is faster (so the directional light has to move faster)

X and Y are just numbers, not related to the X and Y axis

[spark steppe]

the system doesn't

you need a time system which is able to skip/fastforward time

then it doesn't matter what queries the time (and you often don't need specific implementations for fastforward)

[supple dome]

Not sure if that's a possibility for you, but in my case using a Sequencer to control it provided much more flexibility, light angles, colors, shadows, actual rotation, and i can just set the sequencer speed to fast forward

[sick sky]

genius

sequencer would be perfect

didnt thought about that, ill try

[plain cobalt]

Hey all, Im trying to make a bit of code that creates an array 1/4th of length of another array. So if ArrayX has 8 elements, ArrayY has to be set to 2 elements. Not sure how to do that

I can determine what the length needs to be but I dont think I can use something like make array to set the amount of array elements

[lofty rapids]

use a loop and add elements to the array in the loop

start at index 1, goto index whatever the 1/4 length is

so your loop would loop the amount of elements you needed to add, and you add them in the loop body to the array
