blueprint

[inland walrus]

So for example, the target name should be the same either side but for some reason the target on the right side is pulling quest 3 data instead of quest 1

[stone field]

ah. You are populating data in a loop, but then using the 'break' data in a click way later. That's going to break for sure

You probably want to store either a key or ann index or all the data somewhere to get the correct stuff for the correct click

basically you feed the data into the widget, the 1st step looks ok. but then the click can't really know which data it's getting, it's probably using the variables from the last 'break'

so it should be getting the info from the widget which already has the right info, perhaps

If you didn't catch my drift : debug-step through the code, you may understand it better.

[inland walrus]

Thanks for the feedback

I'm fairly new to data tables, it's taken me a day or two to get this far

[mild jacinth]

interesting, thanks

[inland walrus]

Would something like this work?

If each quest has an ID

and everytime you click the button, it sets the clicked variable ID to the bounty ID?

[stone field]

You are still being too greedy, pulling those long red lines from the break to the second stage

Accept that you cannot reuse them

[inland walrus]

Should I perhaps call the data table again then?

[stone field]

yes, that should be fine

That said, I don't like binding events like that either ( in a loop )
that will likely cause you pain as well

I would prefer you to handle the onclick logic inside that widget itself

[inland walrus]

Alright, I'll get it working then I'll look at doing that

Currently it's pulling all descriptions

[stone field]

• create widgets a, b, c, assigned with id x, y, z
• each widget then knows they have to do x/y/z when clicked
  sort of thing

yeah, that part looks ok, but clicking those widgets should happen inside the widgets themselves imo

assuming I understand correctly : each widget has their own "accept"

[inland walrus]

I'm not sure I follow fully but I get the gist, I'll change it/optimize it once I get it working

Currently I can't make it so that it only creates the widget of the clicked quest

[stone field]

Handle it in the widget itself.

[inland walrus]

so just move the same logic across?

[stone field]

Create the mission widgets is fine. Handle the "accept" inside the mission widget.

[inland walrus]

There's 3 widgets, I'm not sure which you mean

1. Bounty Terminal (Master UI for terminal)
2. BountyListItem (Creates the clickable button)
3. BountyListItemDetails (Creates the description/accept page)

[stone field]

I'm not sure what you mean by "clickable button" vs the "accept button" In any case:

I would think of it like this:

• You create the BountyListItems, just pass them a BountyID for each one.
• BountyListItem creates ListItemDetails ( it probably wants to know the BountyID as well. ) ( why bother with having it as two separate widgets here? not sure )
• ListItemDetails Accept button knows the BountyID, and communicates with whatever actor / save etc is holding the list of active bounties

If the place you need the Bounty details is the ListItemDetails, there is no need to be passing the text stuff down through the chain, just let the Details handle it themselves since you can pass it just the BountyID

[inland walrus]

Okay, sorry I'm not great at following, should I start by merging the bounty list item and the bounty list item details into one widget blueprint?

[stone field]

I try to think of widgets as stupid as possible, doing as little work as possible : focusing on visualizing data, and providing an interface for the controller to actually take care of things. ( That said, you don't always have a Controller, and often stuff kind of builds on itself, or a big layout widget is the controller )

"Hi I'm widget, what do I show?" - bounty #44 - "Thanks, will show it"
"I haz accept bounty #44 button, click" - Hey BountyController, the player just accepted bounty#44!

[inland walrus]

I get that xD but I don't know it in node form

[stone field]

The question is : where is the Accept button ( and are we correct that that is indeed the button which we need )
There, inside the widget which holds the Accept button : there we should know the BountyID, and communicate with this Hub that I haz been selected

[autumn pulsar]

Anyone know of good docs for syncing stuff between the animation blueprint and the pawn blueprint?

not sure if I needed to pass a bunch of bools to the animation

[inland walrus]

So Right now the Accept button is not in use.

The only button currently in use is the item list

[stone field]

so pass the BountyID to that widget. And in that widget, Button should have it's own OnClicked

[inland walrus]

So you click the listed bounty > it creates the description on the right side

[inland walrus]

I'm not sure what you mean by pass the bountyid to that widget

[stone field]

add variable to this widget, BountyID

[inland walrus]

Expose on spawn and Instance Editable?

[stone field]

it already has all the rest of the stuff, TargetName, Reward, Difficulty, add the ID

same as the rest

[inland walrus]

Okay done that

[stone field]

pass it in on creation, now this widget knows it's ID

[inland walrus]

Okay so I've done that

Connect bounty ID from the struct to the create widget?

[stone field]

now when the button is pressed you need a reference to the hub which created it, and where you want to handle the accept

There are many ways to skin that cat, but perhaps simple version for now:
Passing the hub as well on creation, a variable "Hub" which gives the item a way to call the Hub

hub could have function "AcceptMission" with InVariable "BountyID"

Then the Widget calls Hub->AcceptMission(BountyID)

https://forums.unrealengine.com/t/how-to-get-reference-to-parent-widget-to-call-function/61179

EventDispatchers are another very valid option, but I find myself being a bit wary of them as used indiscriminately things can get a bit messy

[inland walrus]

Alright, by "hub" do you mean the description side of the screen?

[stone field]

I am assuming Hub is where you create the bounty widgets

That seems to be the 'controller' of the whole show?

[inland walrus]

ah okay I got you

I'm unsure how to get a reference of a widget

cast maybe?

[stone field]

make a variable of exact type of the hub/controller ( ? )
pass "Self" in on create, along with the other variables ( bounty id + details )

[inland walrus]

I'm sorry you have lost me again

[stone field]

In BountyTerminal, where you create the widgets in the loop. Pass self there to the created widget.

In the widget, GetTerminalWidgetReference and you should be able to call functions from that widget

[inland walrus]

You mean here?

[stone field]

Now each Widget will be able to "call home"

[inland walrus]

Where to I pull self from?

[stone field]

just create the Self node out of thin air ( r-click blank space and type self )

[inland walrus]

yep

I have the self I just don't know what to do with it

It won't go into the create widget

[stone field]

Createwidget doesn't have TerminalReference variable exposed yet

Expose on spawn

[inland walrus]

oohhh

My bad I didn't know I had to do that

[stone field]

no worries

[stone field]

now create in Terminal a new function "Accept Mission", give it an In variable of the bounty id type ( string? int? )then call it from the widget

[inland walrus]

an In variable? is that just creating a new variable?

[stone field]

Function details, In / Out, have to add them manually

[inland walrus]

oh yeah sorry my b

[stone field]

now you go back into the list item widget, TerminalReference->AcceptMission

and remember to check what type your bountyIDs are - ints or strings probably

[inland walrus]

?

[stone field]

yes indeed, you should now have things set up to go forth and profit

"AcceptBounty" to keep things all solid : )

you might need to have missions that are not bounties, and if using two names for one thing, it's a trap

[astral ravine]

can someone help me with this? im trying to rotate my object so it follows the path but nothing is working

[inland walrus]

I think we may have miscommunicated 😅

The accept button is here

The button we've been medaling with needs to spawn this widget in

with the correct data

[stone field]

doesn't matter, you now know how to link up widgets to talk to each other and should be able to sort things out

[astral ravine]

i cant even rotate the object in static mesh view either so idk what the hell is going on

[inland walrus]

Alright thanks I'll see what I can do

[astral ravine]

is it splin dir up?

[sharp crane]

Hello! I have a map that keeps loading with about ~100 missing assets each time! When I rebuild, everything will return but will disappear after going to another map. And from what I can tell, it's random which assets don't load in, the number of missing assets is always changing. Where is a good starting point?
edit: The data layer only has 2 assets in it, and functions as expected

[astral ravine]

anyone?

[stone field]

I would sanity check your setup with a primitive cube to verify whether the issue is your setup or your actor

[astral ravine]

its the actor but how do I FLIP the path so it follows the direction of the object

[inland walrus]

Hey, Karma, once more quick question as I seem to have it working.. Any idea on how I'd only make it show 1? when you click another it removes the previous?

[dusky cobalt]

Clear children before you add new one

[inland walrus]

Legend, thanks man

Also @stone field thank you so much for your consistent support

[stone field]

I am a bit confused about what is flipping where, and which follows which.
Please try to compose your question on notepad/notepad++ for maximum clarity

perhaps show a working demo video of the thing you want to achieve, which works with a primitive, versus what the behaviour of your actor is

[astral ravine]

I'm not sure what's confusing.

I want the OBJECT to follow the direction of the spline, or change the direction of the spline, like this

this isnt correct

the red line is suppose to follow the length, not the width

[kind estuary]

I'm making a game where you can change from 3D, to First person, to 2D top down.
When switching i switch the camera location.
Though the controls of the camera WASD behave differently for each view.
How should i handle this. Event dispatchers, and bind unbind as needed ?

[sharp crane]

Can I get help with this when someone has the time? Been struggling to figure it out on my own

[astral ravine]

ughhhhh why isnt this working

[stone field]

Have you checked logs for anything sus?

[stone field]

Separate PlayerControllers for each mode maybe? With a single actual interface so you dont multiply the same code everywhere

[faint pasture]

you modeled it such that forward is not along its length

[dusky cobalt]

Probably you should use Input Mapping Contexts and create different mapping context for each ''mode''. Add Input Actions for each camera move and sort them to each mapping context.

[kind estuary]

I thought about this. Though that will complicate things too. When changing from 2d to 3d, do you spawn the pawn again with a new controller?

[astral ravine]

right but can't I rotate it in the engine?

i used to be able to in UE4

[kind estuary]

is that the Enhanced Input Mapping?

im in UE4 💪

[dusky cobalt]

Yeah i think you should work with this one.

[kind estuary]

🫡

[stone field]

I think you can just switch controllers? It's been years since I did something like that so not certain. Amberleaf's suggestion sounds solid if it is available to you

[faint pasture]

If that's all, I'd just switch on ModeEnum for the different behaviors

[verbal kayak]

I have a one component in BP. the root. It has collision. Doesnt return me sweep hits in any way? why?

how do i move it to get any sweep collision?

[astral ravine]

ok i fixed the orenintation, but why is my spline not repeating every 400 meters? its just stretching it

[faint pasture]

I don't recall for sure but I don't think the repeating is automagic

I think you need to manage instances

[astral ravine]

in a spline mesh actor?

[faint pasture]

does it have any setting for count or repeat distance or anything like that?

[astral ravine]

no

[kind estuary]

so create an enum. then when you press W with enum 3D view, it goes forward, but enum is 2d it goes up (2d forward). is that right?

[astral ravine]

not that I see

[kind estuary]

that might just be simpler and better

i hate destroying and spawning actor to change some weird dynamic

this sounds better hoenstly

[astral ravine]

theres this but it says if its not set then it will use the bounding box, which it didnt

and changing the values just flips the the track upside down

[faint pasture]

look at how the content example with a road does it

i think you need to manage instances

[dusky cobalt]

You can create set of Input Actions for Each Mode and assign invididual logic for each Input Action (event). Then you can just switch the Input Mapping (Mode) to use different set of Input Actions.

[astral ravine]

the what?

[sharp crane]

Of course now that I'm trying to reproduce the error it's not happening lol

[faint pasture]

there's a content example with a spline mesh road

been there forever

[scarlet urchin]

Is there a quick way to make my game ignore all keyboard and mouse input and only accept gamepad input? I want to set it using a checkbox in the settings menu.

[kind estuary]

🫡

[verbal kayak]

why doesnt my location of arrow show correct world position? it is attached to a ball and the ball is set to hold a rotation, but i have force to move it ever so slightly and the ball actually rotates towards the velocity. and the arrow also visually does that. But the world location is not changing at all in Z ... it should decrease or increase when acc/decelerating

And by rotate towards, i mean a nudge of rotation.

[storm solar]

I have a function w/ a time line needing to update positions of certain widgets.
The issue is when I need to update two of these widgets at (essentially) the same time, it halts the progress of the first one to move the second one. How do I fix this? Do I need to make it a blueprint component instead of a basic actor widget.

[faint pasture]

what is that code meant to do?

We can't see what you're updating the transform of so we'll just have to guess

[olive yarrow]

I thought i was storing right, but when i press Drop it comes back with 0 (the BP's original value), however when i pick up/interact with the weapon it shows the variable value i have set on the in world blueprint.

I'm attempting to take this blueprints variables and pass them on to the copy of its class im spawning when i drop the weapon, so i can pick it up and it still have that damage.

Basically, how can i save all the data on the weapon im holding - drop the weapon, and have that same data when picking it back up?

[slender harness]

is there a node that allows me to re-enable a left mouse click? the issue i have, when i load into a game, and then i right click, that enables look movement, when i release, i snap back, but i cant hit the right click again and it re-activate the look.

im controlling the look in the pawn at the moment.

for testing

[faint pasture]

what does it mean to drop a weapon?

why drop a copy

just drop the one

[tribal gazelle]

I'm having an issue with spawning the player at a playerstart inside a persistent level with sub-levels.. tried everything

[olive yarrow]

ive tried detaching the component from my actor and resetting the variable - this works but next time i pick up the weapon the damage variable resets to 0

y'know, i dont have a save system that prolly doesnt help

[slender harness]

sounds like you need to save the damage value in a variable upon drop

[faint pasture]

Are you spawning or resetting something on pickup?

[olive yarrow]

Spawning!

[faint pasture]

Why, just do the opposite of dropping the thing. Attach it, say that it's your weapon now, done.

[olive yarrow]

Hmmm... This mighta been the obvious brains torm I needed. I'ma try it

[faint pasture]

Some people don't do that but I really like just making the thing once. It can have like a dropped mode and equipped mode.

[peak zodiac]

It sounds like you're dealing with a scope issue.

[copper chasm]

is someone well versed in input actions? I'm having a brain fart moment with holding down middle mouse to rotate the camera freely

I would like to click+hold middle mouse, and have nothing happen until I move the mouse along left or right

I currently am able to click+hold middle mouse, but it slowly rotates in one direction - it DOES respond to mouse movement, but it feels like it is doing so against that pre-configured slow rotation

[normal cargo]

is there a way to save the ui of UE? I put the event graph on the top next to viewport but every time i restart the engine or open a new bp, it puts it back in the bottom

[copper chasm]

i think that was a bug for a bit tbh, I'm not sure how i fixed mine, I'll see if i can remember

[autumn pulsar]

if you call an event, which completes first, the event or the inputs after the event call?

[normal cargo]

wdym inputs after the event call?

[autumn pulsar]

https://i.imgur.com/MmH3Ale.png

[normal cargo]

the event and whatever is inside the event then the set function

[normal cargo]

Can someone explain me the logic here? (it works)

How does the Add Static Mesh Component know what mesh I assigned the Set Static Mesh to when its executed after the node?

[lost hemlock]

oh I see something wrong already, scale on true is wrong. 1.2 x 2.0

but the problem remains, it still highlights all of them at the same time

Oh and this is what I tried to do before

but as you can imagine it didn't work as good either

As you scroll, each slot is processed (big ➡ small ➡ big), but im not isolating just the current one to scale up.
Instead, every slot in the loop gets scaled as I scroll, causing the "wave" effect

also the problem is when you start out you start before the 1st selection, im trynna make it similar to fortnite hotbar

So when you start out, nothing is selected at all, you gotta scroll up to select the first one,

[maiden wadi]

The first node creates a StaticMeshComponent and returns a memory pointer or "reference" to that component. The second node uses that reference to set a reference to the asset you want that component to display.

[zealous moth]

I'm trying to do an instant cleave attack that's a semi circle.
I'm doing a multi sphere trace and then get the hits, then do a foreach to get the actors and filter out the dot product's values that are less than 0 (behind).
I'm just wondering if this is way too complicated and performance draining than just making a static mesh, get all overlapped actors and apply damage there...

[maiden wadi]

Depends. You pay every frame for having a static mesh attached and moving with the actor. And you have to upkeep it and make sure it doesn't interact with anything else too. The immediate call to get all overlapping actors might save you a tiny bit, but I'm not sure if it would be worth the rest of the overhead or possible complication. You won't really pay much for an overlap and dotproduct filter anyhow.

[crystal otter]

was your issue solved?

[spare pike]

Is this a good way of finding a target with the highest priority, or is there a more efficient way?

[hard sinew]

https://astricx.is-from.space/2025-01-16_16-30-04.mp4
anyone know what is going on? 😭

look bottom right

[maiden wadi]

Percent is usually a 0.0 to 1.0 value. So you would need to do Hunger divide by HungerMax to get a correct scalar.

[hard sinew]

ohh okay

so its not because of the component or anything, its just because i have no hunger max?

[maiden wadi]

I'm not 100% sure. But using an integer to pull that value would cause it to be zero or 1. Cause anything over one counts as one as well for the purposes of finding a percent.

[hard sinew]

okay i'll give it a go

[pulsar osprey]

unless you're doing that many many times every frame I can't imagine it'll be that unperformant

can always either go to a normal line trace or reduce the number of sphere traces

[hard sinew]

i've changed it to this setup but i still get the flasing

oh wait

yeah its stuck at zero now

[tropic token]

[sturdy sorrel]

im not sure if this is just an error with the preview window in the editor or if it will still be an issue with a fully packaged game but I am having an issue that when I switch my game to fullscreen and then kick the resolution all the way up part of the screen just does not render until I switch the game to windowed fullscreen and then back to fullscreen.

[merry mirage]

It's somewhere you call "UpdateValues" a lot of times, not where the code of Update Values cause an infinite loop

[tropic token]

Oh, I found the problem

[merry mirage]

Awesome!

[little prism]

Hi,
I am working to design a very small (5px over 5px) widget to display progress bar and maybe some small text. However when I place it on the actor (using Widget actor component) nothing about the design look right... Text is fuzzy, the progress bar is not updating linearly but it stutters... Generally looks bad not as designed... Any tips or pointers?

[inland walrus]

@stone field morning! are you able to help me figure out how to add a quest accepted and quest completed boolean for the data table

[stone field]

I don't think you should really store that in the data table. ( actually that might not even be possible? )
I personally think of data tables as just the raw authored information.
I would save the quest states separately in a save slot.

[trim matrix]

You can use array

[inland walrus]

Ah got you, Alright, what would you recommend? (I'm new to save game stuff and only really know how to save variables, I don't want to go too far out of my knowledge to the point where I don't recognise my own code)

[stone field]

QuestSave, arrays of QuestIDs:

• pending quests (available?)
• active quests
• completed quests
• rejected quests

maybe

[trim matrix]

Boolean Array, when you take a new new quest, a new index is created for that quest. Which makes it possible for your quests to have different IDs for each of them and use however you like

Let's say, there is a quest which you didn't even take, so

You search it with an array, if there is no ID (Which It is not for not taken quests) you will display an different UI or color of UI or style

It is just your creativity

[inland walrus]

Thanks but I'm still not sure how to go about it in blueprint terms

[inland walrus]

Would this be a dt? or just variables?

[stone field]

BP_BountySave, with variables

[inland walrus]

Would it have to be a new blueprint or can I put it in my already bp save game?

Also what type of variable would they be? An interger?

[stone field]

What format is your BountyID

optimally you might actually consider using the string keys that you use to identify each quest in the data table across the board

[inland walrus]

Float, so I can have my main quests as whole numbers e.g. 1.0 and the side quests for level 1 as 1.1, 1.2, 1.3 etc

[stone field]

hmmm... unusual but ok. Float comparisons can be a bit dodgy so I would not recommend using them like this really

[inland walrus]

Alright so I use a string?

[stone field]

yes, I think that would be better if you want to use this 1.1 etc convention

[inland walrus]

If I change the bounty ID to a string I will have to redo parts like this?

no idea why my screenshot turned out like that xD

[stone field]

probably yes. I gotta go, carry on : )

[inland walrus]

Alright thank you 🙂

[primal hare]

Is this genius simplification or a bad idea? We really need the comment/review section back on product pages. https://www.fab.com/listings/2d251ddd-5bed-4a7b-b506-71b72238c0a4

[shell widget]

Hey, hoping someone can help with a rotation problem I've been trying to solve.

So I have 2 actors, each with an arrow component that points in a certain direction (can vary depending on the actor that inherits from it, so the relative rotations won't always be the same). I want to find the world rotation to get one of the actors to face in a direction such that the arrows of both actors are lined up and facing opposite each other.

So I have a function that takes in 2 arrow components and returns a rotation, but I've been struggling to get the correct rotation. Can anyone help with that?

Edit: Figured it out, no idea how it works, just randomly trying different things, but it does mostly work.

[cunning tendon]

Hey this a blueprint flow I created to switch from my car pawn to player character only problem is when I do switch from my car to player I still have the input from the car https://cdn.discordapp.com/attachments/978036466544422932/1329403849160523817/image.png?ex=678a3750&is=6788e5d0&hm=f27a2423d49de23a8235dffbcda2b9cc2351693b7e1951df11fc642e0a426554& im also not able to disable the input https://cdn.discordapp.com/attachments/978036466544422932/1329403946648862811/image.png?ex=678a3768&is=6788e5e8&hm=520ed03e1ef7fb54eeb21503db4e8dd00454f1720db10c2dbabd3173a5095310&

[calm cargo]

Hmm will a set of UObjects magically auto remove elements from the set if the objects are destroyed?

[calm cargo]

This seems like a good and simple idea, the fact that it's global & generic gives it merit imo

there is one arguement to be made, and that its usage causes some obfuscation of the system architecture

when an input device changes, like in the example, it'd help the reader know what actually called the thing, and know its type as well

but this is not very significant, especially if one can look up the identifier's usages in editor

[dark drum]

It would depend on the use case. Having everything send some sort of data object can become clunky and bloating as you're project scales. Sometimes using a gameplay tag is just as effective.

Personally however, I wouldn't use it as I have systems that do specific things that has there own event dispatchers that are called. If anything needs to know what it's doing it would just bind to the event dispatchers on the system in question.

[calm cargo]

yea, also agreed that the gameplay tag (or even just a string) could be more convenient than some object, hmm actually maybe less so because it'd be easier to just rename the identifier if its name should change

[dark drum]

uObjects won't get garbage collected/destroyed if they are referenced.

[calm cargo]

oh shi thats a very good point, I keep defaulting to refs as weak refs in my silly head

ty

[primal hare]

Thank you guys. Some very good points!

[sand yacht]

does anyone know why changing the yaw is doing the exact same as changing the roll?

shouldnt this be making the camera turn left and right?

[merry mirage]

I think this is very cool for certain things, but not as useful as it first seems, a lot of the time you can accomplish similar results with interfaces, but sometimes you just need a lot of different things to react to a certain event, and then something like this can be invaluable. imho

You could also setup a system such as the plugin very easily yourself if you aren't afraid to touch (relatively) simple C++ code

[violet bison]

I think its about the integer first part...
(if someone answered that already sorry for the disturb)

the divide's output is integer (1/X -> 0)
and the divide will return 0 if less than 1

[narrow sentinel]

Anyone know whats going on here, I have my Struct and then within the BP

And then I have my variable within my BP but for some reason it's saying I can't set that soft referece in class defaults

but i'm not trying to set it within Class defaults

[violet bison]

compile it?
or restart the editor

[narrow sentinel]

compiling it didn't seem to fix it

[slender harness]

do you want something in it?

[narrow sentinel]

so i wanted to set the soft reference to actors within my level

[storm solar]

The code updates the position of the widget over time (1 second).
If this is triggerd twice back to back, it stops the movement of the first widget.

[craggy belfry]

Hi, when I change the position of objects in the grid panel, they slide downwards. What should I do to make it go upwards?

[gray lantern]

If im building an inventory system does it make sense to put basically ALL my functions in the main component and just do event callbacks from all the children widgets so that all my logic is basically in one spot?

but then I can still have all my seperate widgets

[merry mirage]

If you want a centralized system then that's a good approach, but it will make it harder to decouple and making changes to particular parts of the system could be a nightmare

[gray lantern]

Don't you want to avoid circular references though, say my inventory has child widgets that call up to the parent widget/component to change things I mean

for a single player game that doesnt' really matter too much if the inventory is basically gunna be consistently referenced through out right?

[merry mirage]

You don't need circular references

You would definitely use delegates/event dispatchers for this though

[gray lantern]

What are those? I don't fully understand

like a delegate

[merry mirage]

Mathew can probably explain it better than I ever could
https://www.youtube.com/watch?v=sEcoWGrF1Hg

[gray lantern]

I'll investigate thank you

[merry mirage]

No worries! Working with delegates (and interfaces if you don't already) will make your life a whole lot easier

[gentle urchin]

Component > interface 😄

[marsh sonnet]

Newbie, putting together a visual novel using a HUD: I have a settings widget, and on that widget, a button to return to main menu, which then prompts you to check for unsaved changes, and if you click "yes" to return to main menu, restarts the level... but there is a sound effect within the visual novel HUD (the letters typing out) that continues to play for a bit when they restart the level. Any ideas on how to make it stop playing?

[shadow flame]

I have a Media Player that's simply not playing. Blueprint calls to play return false, it loads playlists just fine, it's just not playing media.

All checks on the playlists say that they've loaded the video files. The video files appear to play fine when loaded in the editor. They were playing a few days ago, and now the media player is no longer playing. I'm not sure where to even begin looking for a solution to this.

[dark drum]

Is it playing while it's loading the level or after?

[bronze mirage]

anybody here mess with anim class layer linking? i'm trying to determine when it's necessary to manually unlink an ABP but the docs (and the internet in general) are not helpful. docs say that if a layer is not "grouped" then a separate linked instance is allocated, but i can't see anywhere to specify a "group" for an animation layer.

[warped slate]

Hey Developers!! Does anyone here have experience with building systems? 🤔 Could really use a hand, all the research and tutorials have been unhelpful to say the least 🫠

[floral wyvern]

is this really the only way to call a delegate from function argument?

[dark drum]

This isn't how you would normally used event dispatchers.

[dark drum]

What are you wanting to know?

[floral wyvern]

I just want to call this event

I use it for bind too, but in case of error I just want to call it

so I have two variants

Hardcode or self dispatching

[warped slate]

Everything?? 🙃 😬 😂 I have it coded out and it should be working but it isn't and I can't seem to figure out why, could really use a second pair of eyes!

[dark drum]

For context, event dispatchers are a way for Actor B to know when Actor A has done something and thus do something itself.

So if Actor A has an event dispatcher for 'OnPickup', you can have Actor B listen for the 'OnPickup' dispatcher to be called (when actor A is picked up, it will call it) and then do something.

[floral wyvern]

I have a function that spawn a level. When level shown, I delegate an event to this "bind on level shown"

In case level failed to load, I want to call THIS delegated function. How I can do it?

How to invoke this delegate event by my own hands? Just like func()

[dark drum]

You'll need to show more of what you're doing. I'm not really following with these partial screenshots.

[dark drum]

Did you follow a tutorial?

[floral wyvern]

Question is simple - how to call event delegate?

I bind it, that ok. How to CALL it in another case?

[warped slate]

More than one! And neither have worked for some reason ☠️

[floral wyvern]

I can call it only in C++?

[dark drum]

Any bound delegates are called when the event dispatcher is called. I'm still missing context in terms of your setup but I'm not entirely sure event dispatchers are what you're needing. Why not just call the function?

[floral wyvern]

Nope, I knew this. Question is how to invoke it without binding inside function

I just want to call this red function in case when level not succeed

[dawn gazelle]

You can't. You're using a delegate to listen to the event being called.

[floral wyvern]

So I cant invoke delegate, only bind it?

So this creepy stuff actually working? But i dont like it anyway

[dark drum]

Building systems tend to have a few elements. The UI which is the players window into the pieces they can select/place. The second element is then using their selection to generate data which is stored somewhere. This is normally a transform and selected mesh. (this might just be an int depending on the setup) then the 3rd element is displaying the data the player has generated. Normally through the use of instance static meshes where and pieces not get displayed are added to the relevent ISM using the transform data generated by the player.

[dawn gazelle]

This is calling the event. Anything bound to it would execute.

[dark drum]

Whats the delegate?

[floral wyvern]

Red wire

[normal raft]

hey.. all just to report .. i solved my problem .. the solution was simply in the Move Forward Macro (which was a 3rd person implementation)... what happens in such a scenario is you rotate your metahuman mesh which makes the camera work perfectly .. but then your controller orientation is incorrect .. how to fix it .. is with the get base anim rotation node and just plug that into add movement input .. the scale value takes care of the rest .. its crazy and brutally simple but it works 😄

[floral wyvern]

If level sucess, I want to BIND

If level fails, I want to CALL (invoke, whatever)

[dark drum]

Which is what?

[floral wyvern]

Here it is - red wire is a DELEGATE (created event)

How to make this type of node?

[warped slate]

Yea, I have a data table to store the building I want to be able to place, I have the mesh, I have the line trace I have the mesh components etc. but it just doesnt show up. like there shouldnt be any reason for this not to work, I followed every step, missed nothing and even rewatched yet for some reason it's broken ☠️

[floral wyvern]

I can bind it, but how to call it immideatly? My variant with immidiatly call from event dispatcher is not good solution, what if it will be called few times until unbind

[dark drum]

Yea you can't just call a delegate in BP. Delegates in BP have to be bound to an event dispatcher, calling the event dispatcher would then call all the delegates.

[floral wyvern]

but this stuff could be dangerous isnt it?

[dark drum]

You've still not said what the delegate is so it's difficult to offer any recommendations.

[floral wyvern]

its a red wire

link to an event

OnSpawnEvent === Delegate

[dark drum]

i'm refering to the function/object that makes up the delegate.

[floral wyvern]

It doesnt matter for sure

I create this event dispatcher just for calling this event

So answer is no - we cant call delegated event in blueprints for some reason

Only in C++

Creating UFUNCTION with one field that will call delegate is the only solution))0

[dark drum]

I can't say I've ever needed too. Delegates tend to be for triggering an event at an unknown time later when another event happens. It sounds like you can just call the function directly.

Failing that, you can always use the timer by event next tick and have it call the delegate the following tick.

[floral wyvern]

Thats sound like a solution - thanks!

[dark drum]

'Timer by event for next tick' 😉 don't call timers with 0 time. 🙂

[floral wyvern]

got it, thanks so much

I hope it will not break)

In this case, I just need to write simple ufunction that will call delegated event

[shadow flame]

So I reverted my commit to a previously working one. Made a new branch. Built and ran the project, the Media player played. However after about 30 minutes of work on a separate widget that doesn't touch anything connected to the media player, it failed to play again.

[dark drum]

as an FYI, it will call it the following tick so if there's anything in the given tick that needs the delegate, you might run into order of operations issues.

[floral wyvern]

Yep, in this case I need custom simple ufunction

But level loading is a time consuming process, so calling it on next tick if level failed will not be a problem

(I hope)

[dark drum]

Well the level load node you're using is a blocking load so it'll stall the tick until done. You might be needing the async version which will happen in the background.

[floral wyvern]

That node will return true or false in current tick

If true, it will bind an event to "on level shown", that can took a lot of time

If false, we will call this event on next tick, so this is quite the same

(next tick and "took some time" in this case is pretty the same result)

[pure jolt]

Hello Guys, how can I have my AI facing only left and right but can move to all directions and when coming to attack me come to the right or left to attack me efficiently

[marsh sonnet]

after, but i have time dilation set to 0 when i'm on settings menu

[brittle oxide]

How do you remove items from an array, and 'clean' the array indexes to 'collapse' the gaps where the removed/empty items were in their indexes

[lofty rapids]

probably with a custom function

[brittle oxide]

no native functions? aight

[surreal peak]

The native functions should have an option to resize usually.

[brittle oxide]

Which native functions do you mean

[lofty rapids]

you can resize, but is there one that clears empties out ?

i figured you would have to build a custom function for that

[heavy wagon]

Hello, unsure where to post this question but seeing how spline components can pretty much only be found in blueprints I guess I can try here 😅 I'm trying to figure out if there is any way to change the origin point of the spline? it defaults to the first spline point but I would like it to be the center of the interior...

[pastel spade]

Any ideas?

[marsh sonnet]

Okay, trying again. I have a visual novel with multiple HUDs for settings, etc. I'm now trying to combine them into one HUD_Manager BP and use a widget switcher. The issue is I have different music and sound effects that play on each widget, so is there a way to make the sound active for only the active widget in switcher--or is there a better way to do this? Open to all suggestions, or links to tutorials!

[pastel spade]

That was for me?

[marsh sonnet]

Nope--that's a question from me to the group

[gentle urchin]

you're already using a widget switcher, so you can use the active widget index to know which music or whatever to play ?

[shadow flame]

Identified my issue with Media Player failing to Play.
All of my playlists had loaded media from a designated source. That source was blocking a loading function that searched by name for the videos.

[marsh sonnet]

Hmmmm so I would set the music within the manager, based on which is the active widget? That would solve my issue for the music, but not the sfx playing the typing sound for when the dialogue shows

[gentle urchin]

well if you have a manager of sorts, you can define "Sets" of vfx,sfx,music etc to use based on some identifier (hello there FGameplayTag)

then you'd just have a public method to that manager setting all these things with a little swosh

[sturdy sorrel]

anyone know if there is a fix for the attached behavior when switching display mode or if it is just a bug with the in engine preview?

[gentle urchin]

there's a thousand ways to do this, and surely you can make them soft pointers and all that jazz

but the principle would be the same

Any sound that is played, be it music, SFX, typing sounds, button clicks , is provided by the manager

manager has complete control of it with a single public method for updating the active "Set"

[marsh sonnet]

Ooooo okay! That makes sense

[gentle urchin]

Could have this in a DT, or DA if you care to

[marsh sonnet]

That you so much!

I've never set up a manager before for huds, do you use interfaces to grab refs for them for when a button press on one leads to the switch, or event dispatchers, or?

[gentle urchin]

my manager would just be a component

in some player owned logical class that I can easily access

PlayerController could be one such class

widgets get it with GetOwningController
HUD uses GetOwner iirc

if its single player you can just GetPlayercontroller[0] from wherever

then get Component by class

Manager classes are neat, as they give you that one single class responsible for all things related to X

[marsh sonnet]

Ohhh okay, I haven't worked too much with components, sounds like I was thinking about this all wrong--gonna experiment with using component and playercontroller!

[gentle urchin]

You might also want to use Eventdispatchers

so that relevant classes (widgets, hud, whatever) can be notified whenever something has called the public method for changing the set

so they know to update their relevant variables (if needed)

[marsh sonnet]

Tysm!

[slender harness]

Anyone have an issue, where they have a widget that does not want to show up after you package, but shows up in UE just fine when you test play

[little prism]

Replying to my question for attention as I didn’t get any response… any ideas?

[dusky cobalt]

I mean it kind of looks exactly like in the editor, just doesn't show the text at all probably because it got updated with null and the progress bar probably didn't get updated at all? Try maybe first unconnect pins that are trying to ''update'' the variables (% and number), and just show the widget as it is with manually set variables (99% and % on progress bar). Then when you got it, try to work with the Widget itself and just do changes on the components (sizebox, borders, pb, text) and see how things work when you start changing them, that way you can check what was set wrong.

Also in this editor of widget you might want to change here to Desired on screen so you can see it a bit more ''live'' how it behaves.

[dusky cobalt]

Widget Component on actor in the ''world/screen'' ?

[slender harness]

widget

[dusky cobalt]

just widget that you add to the viewport or add as a child to somewhere?

[slender harness]

add to view port.

i have another widget, shows up without issue

[dusky cobalt]

mind showing code how you are adding it and where?

[slender harness]

normally i wouldnt mind, i would show, but ive done a few different things and have moved around where its called.

Ive called the main UI in the PlayerController i have set up, which it functions. Ive tried calling it seperately, within and outside. I also dont mind hopping on a call

[dusky cobalt]

just show code where you are adding the widget that is working and where you are adding widget that doesn't work

are doing it in the HUD class?

or y ou have your main UI in the player controller and there you call to get HUD and add to viewport?

[barren tangle]

Hey

how do you manage that connection?

with an enum?

[slender harness]

here is me calling the overall UI that does work in the player controller

[dusky cobalt]

you ask how to do it with enum or what? you need to provide row name (variable type of Name) to get row of that data table

[barren tangle]

do i have to enter the name manually?

if i have a huge list of data table

[slender harness]

@dusky cobalt here is what it looks like, that green highlighted spot with the card wil not show up when i package the content

everything else shows up with out issue

[barren tangle]

do i really have to call with the correct name? can i have a drop down list or something?

[slender harness]

however in simulate, or whatever it shows up

[dusky cobalt]

you are calling that function GetColorsTable somewhere where you would provide name of DataTable ROW

[slender harness]

sorry it took me a minute to grab it

[barren tangle]

yes, and is there a way to easily provide the name? that is my question

or i have to hardcode the name?

[dusky cobalt]

Ok, so I guess this green thing is a wrapbox or some kind of pannel that is in MainUI already, yes?

[little prism]

The values update as intended. I’ll try to make a video if this and post it here or at least set of screenshots.
You can also see on the last shot from the gameplay that left side of the widget is crooked, not like in editor

[slender harness]

yes

[dusky cobalt]

Ok, so you probably created somewhere MainUI (Create Widget MainUI), you saved this as variable after creating (if not, u should do it).
Back to ''green'' panel, you should make sure it's set to Is Variable in the MainUI Widget Editor.
Then you can access Get MainUI, from there drag and Get GreenPanel.

After you Get MainUI, Get Green Panel, you can
Create Card Widget
And that Card Widget, you can add to Green Panel as a Child. (Add Child to WrapBox/what ever ''panel'' you added there).

[slender harness]

double checking

[dusky cobalt]

I don't understand ''hardcode'' the name part. It really depends what you want to do, whatever name you provide when you are ''calling'' this function from anywhere **GetColorsTable ** will be put to Get Data Table Row and then you are returning.

Theme Name, this is your ''input'' which it depends on you how you will let player ''enter'' it.
In other words, you give Row Name (anywhere you call this from) and you get in Return color of that corresponding Row Name.

[barren tangle]

i will create a BPFL GetRowNameFromEnum

like that i will provide the enum name > it will convert the enum name to the name for my data table

like that i will avoid to hardcode the name when i call the function

Something like that

i was wondering if there was a non annoying way to do that

[dusky cobalt]

Its not annyoning I think if it's how your logic is supposed to work.

[barren tangle]

sometime there is some node that exist but no one know to do the same. my question was more oriented like that

is there a kind of things to do that, a feature that exist already to do what i'm doing ? 😄

[dusky cobalt]

Wait, why not just get Enum to Name ?

it's going to give you number instead of ''string'' ?

like just skip the ''switch'' ?

[wild pumice]

Hi, I'm having a hard time finding tutorials on creating a Battle menu like an rpg, where you can select Attack, Skill, etc. and it cycles through the options. Most of the resources I'm seeing handle things like Main Menu, Options menu. I know they will function similarly, but does anyone know any resources that do a combat menu?

[barren tangle]

so tha twas my question !!

😄

i will try 😄

thanks

[dusky cobalt]

try to print it for testing if its printing number or actual name of ''enym''

[barren tangle]

yes i will try 🙂

if it return the name that will be great

😄

if not i will continue with the manual conversion

[dusky cobalt]

I think you may need to first convert it to string and then to name

[slender harness]

im going to take about 30-45 minute then come back to this.

[dusky cobalt]

Try to put these things into smaller tasks. That is very general thing you want to do. Think if does player ever really usess UI buttons in rpg to attack to cast spell? No, you click Q and cast Q spell. Which means, that probably after you click that UI button you want to spawn somekind of indicator of the spell, and then by clicking again you spawn it. but these functions ''Get Idicator'' ''Cast Spell'' are programmed probably somewhere else, so you just call them with this button. Unless you want menu where player chooses skills before going into the fight? Need more details on what you exactly want.

[barren tangle]

no it return the indice name of the enum (enumName0, enumName1,...)

[wild pumice]

Something similar to Final Fantasy 7 Rebirth. You walk around Real time and at any time you can bring up the Commands Menu to select a skill, spell to cast or item etc.

Bottom left corner. It expands to show your selections.

[barren tangle]

this is strange that there is no existing node to do that convertion from Enum To Name when you know Data Table exist

[gentle urchin]

Not ment to use enums as data table row names

They dont scale above 255

[barren tangle]

yes but it will be more easy ??

you can't have more than 255 enum name?

[gentle urchin]

No

[barren tangle]

ha ok, make sens

[gentle urchin]

Enum is a byte value

Id suggest using gameplaytags if you want a list of predefined strings

Useful for many other things aswell 😎

[barren tangle]

im reading the documentation, i don't have the feeling that it is for my use case. maybe i don't understand the concept

[dusky cobalt]

Can I get Collision Sphere and Attach it as a Child to Static Mesh? So the collision Sphere follows the static mesh? Preferably I would like to do it with node, not manually because I have parent with collision sphere, and then childs have ''different'' static meshes.

Attach Component to Component?

[floral wyvern]

Greetings, I need some async wizard here

I have a dungeon generator, and want to optimize it with async load node

But how can I managae it? Where store data until the asset is loaded? This node can spawn in the same room a few times, so maybe I don't need to do async load if that's level was spawned somewhere before?

If I understand conception of Async Load right, we dont need to load same asset twice. So we can skip it loading, and use a structure to hold data until load, right?

[pallid dagger]

what exactly are you optimizing? if asset is already loaded it will skip heavy part and call delegate (complete node) very quickly

[floral wyvern]

I want to pass arguments into delegate, in this case - location and rotation of the level

My goal - is preventing game freeze on dungeon generation

I load A LOT of small sublevels at the same time, so Async Load Asset can create needed delay between spawns, but I don't know how to pass arguments to delegate

(F Handle Load Level function is just a Load Level By Name)

[pallid dagger]

directly connecting pins from event not working?

[floral wyvern]

Of course not, that's Async function

So If you will connect pins, you will have arguments from another call of this function

So we need to pass arguments into delegate, but how?

[pallid dagger]

C++

[autumn pulsar]

For animation notify events, am I better off doing the logic I want to do in the animation notify itself, or call an event on the main actor?

or does it really matter?

[pallid dagger]

as a workaround you can move initialization into level's BeginPlay or one of it's actor's BeginPlay. Those actors can report to some global entity when they complete loading assets so you can manage when to let next level to spawn e.g. N of total per tick

some randomized stuff can be provided by mentioned global entity

[granite nacelle]

I have an issue with a widget. So what I want it to do is only show when a door is locked and I don't have the key, I can't tell where to put the blueprint exactly.

[faint pasture]

the answer was inside you the whole time

AND

the branch that shows the widget, your case isn't if the door is shut, it's if the door is shut AND the interacting person doesn't have the key

or you can have 2 branches

Interact -> is it locked? -> yes -> do they have key? -> yes -> unlock and open
-> no -> open -> no -> show widget

[marble badger]

How do I get the user's current continent? eg: SA

[granite nacelle]

So put the third branch on the second branch of the interact

[faint pasture]

If it exists that'd be through the #online-subsystems

[marble badger]

ok

[granite nacelle]

I don't understand this format but what i did was add the widget code to the false of the last branch

I'm wanting to store a table of SFX for footsteps and want to drive it by physical material. What would be the best way to store a map for the SFX?

I am pausing the game on tab key press through IA, the problem is when the game is paused input actions doesn't work so i can't unpause the game i can add a UI button in taskbar but is there anyway that my tab key( IA_Taskbar ) works even after game is paused?

[maiden wadi]

Double click the IA node, it'll take you to your input action definition. There's a setting there.

oh 😆 thnx

[hard sinew]

I followed a tutorial about 3d characters in the ui using 2d scene captures, but for some reason, my scene capture doesnt update in real time?

and it tends to randomly do this

[shy matrix]

Did you check that update on tick is on in the scene capture component?

[hard sinew]

yup its enabled

oh i fixed it

i had to place the pawn into the level

it finally worked 😭 but how could i get the input to pan around?

[maiden wadi]

The scene capture component works as a camera more or less. So you would need your input to move the scene capture component.

[hard sinew]

Im unable to make it pan, even though i even enabled the input to be game and ui

[hard sinew]

how could i get this on right click?

[glass blade]

Hi, i have logic where after consuming a water bottle, it automatically re-draws the previously equipped weapon,but it won't play the equip animation for the one controlling that character, but the animation is visible from outside.

This logic works in single player testing. Where should i look if i want to debug this?

[storm stream]

Question, why my spawned actor blueprint do not prevent mesh clip through it but placed the same mesh on map does?

[storm stream]

simply replace event tick to mouse event on hold, in ue5 there is something like "enchanted input actor" u can define if it click/hold and some other options. If ue4 doesnt have enchanted input actor u can make bool on mouse input

[hard sinew]

I also have updated it to this:

https://astricx.is-from.space/2025-01-17_21-21-33.mp4

But I'll try with enhanced input actor

[hard sinew]

Wait I'm in ue4 why are you even suggesting this

[storm stream]

well, i didnt know that ue4 dont have it 😄

[dark drum]

If you're using 4.27 (the last version), you can enable enhanced inputs in the plugin settings. UE5 was just when it became the default and the legacy system became depreciated.

Personally though, if you're near the start of a new project. I don't really see the point in using an older version.

[hard sinew]

Ahh okay

[hard sinew]

I have quite a lot of stuff and I just personally don't like ue5 because it feels buggy

[hard sinew]

also didnt mean to come off rude or anything. I was just asking 😅

[dark drum]

It feels less buggy to me.

[gloomy hare]

hey guys! im currently using Dungeon Architect in my roguelike game, and im quit struggling with how to edit it

[slender harness]

I wanted to make sure you know that i appreciate your help. I still can not get this to work, so i am going to tear this down, then go back to the drawing board to see if i can come up with a different way of doing this. Perhaps with visual interactions.

IE using actors and such

[jagged epoch]

I moved the input from the controller to the character, and I created a function, but the callback didn't work. why?

[elfin goblet]

I have a blueprint for a Flipbook that i want to rotate when moving left and back to normal when idle. So far it works but the issue is since its a 3D game , when my camera has turned enough and it detects me walking left (but towards the right side of the start of the level) it flips and makes the character sprite face the incorrect direction. Is there a fix i can try to fix this or would this be easier to do with something that detects if i am moving with W or A key (not sure if controller or if i map stuff differently will affect that in the long run)

[proper hull]

Hello, I have a strange problem of reference (Unreal 5.3)
I have a variable "TSoftClassPtr" that "loses" its reference each time I restart the editor
This problem only appear when the referenced class is a blueprint child
You can see on the screen that the reference is still there but the class/file is not valid anymore, I have to open the referenced file (or reload manually) for it to work
Does someone know how to fix ? Or do I have to use TSubclassOf instead for blueprint class reference

In this video, a InputActionDataTable is created with these elements
The Select and back buttons are explained and work fine

But it is never explained how to make the TabLeft and TabRight button functional.
To clarify, these are for switching tabs in the menu using the Gamepads shoulder buttons.

I really want to have gamepad buttons be interactable within Widgets and I think this is the way to go
If anyone has expierence with common UI please help😭

I found it
You need to select the InputActionDataTable in the CommonButton, and then Select the action its associated to

[ripe pier]

So I want to make an infinitely generating road that works in run time with bends and such. Can anyone help me out?

[vague moth]

Should look into splines and spline meshes
There is a good unreal live about it

[proper hull]

I found a fix
Before I was using IsValid() to check if the TSoftClassPtr was valid and then use LoadSynchronous()
I tried UKismetSystemLibrary::LoadClassAsset_Blocking and it works now even with TSoftClassPtr on blueprint class

[dark drum]

If i have an event dispatcher on a component and then in the actor the component is placed on, create an event for the event dispatcher, is it supposed to unbind the event when the unbind all is called? Doing so seems to render the event useless as you can't even use it to rebind.

I guess I naively assumed these were a permanent binding.

[pallid dagger]

you can't even use it to rebind
explain

[dark drum]

If you attempt to rebind it you get this error.

[pallid dagger]

verify that signature is correct (types of input params are matching)

[dark drum]

It is, the event is created by right clicking on the component > add event which creates an event for the event dispatcher.

It fires once and then because of the unbind all, never fires again.

[surreal peak]

Pretty sure that Event is a bit more special than your usual one.

If you want re-bind behavior you will have to create your own custom event or function and bind to that by hand.

But funny idea to unbind the special AddEvent K2 Event haha

[pallid dagger]

click on event dispatcher and screenshot details panel

[dark drum]

Yea, i guess it's why I assumed it was a permanent bind. (Incorrectly) 😅

[surreal peak]

It's an automatically added binding from the Component into the Actor.
I know what you are trying to confirm, but the problem seems to be related to it being a "non-normal" custom Event due to that.

It's the same as adding a BeginOverlap event from the Details of a CollisionComponent via the Green Button at the bottom.

[dark drum]

It's nothing special lol.

[dark drum]

That's a point. o.O would it mess up those nodes as well if I was to unbind all overlap events.

[surreal peak]

Yeah that's what I would expect. Just that no one really tries that :D

[dark drum]

So what we're saying is that it's a bug right? 😛

[surreal peak]

Potentially, yeah.

[warped juniper]

How would you approach making an overlap check using multiple primitives, in a way that overlapping multiple colliders at once counts only for one event?

[dark drum]

I can't see anything on the bug tracker so I'll do some tests and submit it if needed as it could be an easy way to break stuff. :S

[surreal peak]

Keep track of whatever you overlap and ensure that you only call your event if that something is invalid

[warped juniper]

Hmmm could be...
I wish we had what godot has.

In that engine, you can create an overlap parent that is made up of multiple collision enabled objects. They act as a single unit and thus only one overlap applies when one or more of its children overlap.

It's the one nice feature the engine has I wish was more taken into unreal

[surreal peak]

You'd have people ask for the opposite

[warped juniper]

Yeah of course, but Godot has nice things Unreal could pick up

They have by default cylinder primitive collision shapes... I absolutely NEED that

[lusty birch]

you have cylinder in ue

[surreal peak]

Keep in mind that you should choose the Engine for your project.

If Godot fits better, then you might want to consider using that.

[surreal peak]

UE only has Sphere, Box and Capsule.

[lusty birch]

aint that same thing

abit more rounded

:p

[surreal peak]

:P na

[dark drum]

I'd love a cone. 😅

[lusty birch]

never thought of that but for wheels could be nice? I assume they use convex collision now

in their sample projects

[warped juniper]

Nah Godot is not it for me... It just has a handful of nice things against Unreal's trove of essential features.

Afaik, you could create your own custom collision shapes with CPP

And turn that into a plugin

Thing is cylinders are specially expensive when compared to spheres and capsules so it can make sense why Epic chooses not to include them by default

[marble badger]

HI, sound cue folloff distance not workingI set Inner Radius to 33000 and Folloff to 67000, but when my character moves about 1000 cm away from the emission source, the sound starts to lower until it disappears.

[crude helm]

Hey folks, quick question.

I was going to have a Set<string> in my bp, mainly for a fast check, like set.contains(x), but then, I realize that you can't iterate over it without having to copy the set to an array.

So, if I instead, make a Map of nothing, a bool maybe, it would allow me to still have a fast contains, while keeping the For Each Item using map.keys.

Is that too silly? or is like a better way to iterate over a Set without having to copy the entire thing

[remote meteor]

map.keys is also copying to a new array

you dont really have a choice in bp sadly

only doable in cpp

[faint pasture]

There are math reasons why Unreal has no primitive cylinder

[warped juniper]

Yeah, I can imagine. Although I have gameplay reasons atm where I need a cylinder type shape in some designs

So you say it'd be non viable to try to implement cylinder shapes?

I know there are some workarounds though

For example, I know Tekken uses 3D cylinder meshes hidden from rendering for hit detection, which are parented to the character armature but with locked rotation, so only their location gets changed.

[faint pasture]

https://www.codercorner.com/blog/?p=1303

Just use a cylinder collider. You can make it high poly enough to basically be smooth

What are you actually trying to do?

[warped juniper]

I could make a dynamic mesh that updates polycount as required to keep some performance...

[faint pasture]

How big will this set get to?

[faint pasture]

Do you know what the perf hit of a 1k poly cylinder is?

[warped juniper]

A cylinder shaped area around the player used to detect actors around the player based on horizontal distance. It breaks when using a sphere / capsule radius type detection.

[warped juniper]

Not for collision specifically, which is why I was hesitant a bit.

[faint pasture]

How does it break?

[crude helm]

into the thousands, but I don't think it will pass 100k, it should be like 5 to 10k, unless I messes it up some how 🤣

[warped juniper]

Basically when some verticality is involved. Like I want the player to be able to interact with any switch within 300 units of them, from the X Y axis alone, as an example. However, if using a sphere radius of 300, a switch 300 units away but higher than the center of the sphere radius would not be within that range

I have tried to think of some solutions for that. Some better, some worse, most very hacky.

[faint pasture]

I'd use a sphere and math

[wild pumice]

My animation montage that was working before suddenly is rotated incorrectly. On the right preview the animation itself has the correct orientation, but the montage is now facing upwards.

[warped juniper]

Hmm... I think I have an idea for this.
But it relies on using a radius 0 sphere on thw switch to check against for overlaps.

[faint pasture]

why? Just have a sphere of radius whatever you care about and then check that location.z - yourlocation.z > SomeThreshold

[warped juniper]

That could work too. Same result either way

[wild pumice]

Now also when I create new animation montages from the animation sequence, the new one also faces upwards.

I restarted Unreal Engine and now it works after changing literally nothing.
Wth Unreal Engine 💢 😡 give me my 20 mins. back

[surreal peak]

Pretty sure that's not a runtime node.

Unless you are aware of that

This looks like it literally creates a new level asset in the current level

Optionally moving selected actors from the current to the new one

[tawny flame]

Totally aware, was just hoping someone might have seen a tutorial or docs on it. Had more particular questions about its use in editor-scripting, I should probably delete the question here to avoid duplicating.

[surreal peak]

Yeah, gotta remind you that crossposting isn't allowed

[tawny flame]

Fair! 🙂

[surreal peak]

The node doesn't look too complex. Hook it up with a button and give it a path to some folder and see what it gives. Path probably need to include the new name

If in doubt, check its c++ code

[brazen stirrup]

anyone know how to get a 3d widget to be clickable?

[broken wadi]

Set the input mode on the controller to be ui or game and ui with the widget as the target like this:

[brazen stirrup]

ah I see

[broken wadi]

the straight line coming out of As Player Controller is for something else btw

[brazen stirrup]

how do I focus on the 3d widget?

this is what i have so far

[broken wadi]

Pass in the widget

[brazen stirrup]

it doesnt let me:

it says widget component not compatible with widget obj ref

[broken wadi]

For my game there's a BP_Screen players can interact with. It has mesh and a 3d widget component. I use Get Widget from the component and feed that into the Set Input Mode

[brazen stirrup]

yup just done that

its not even hovering on the 3d widget

[broken wadi]

can i see an updated screenshot?

I added a box collision using overlap to toggle the input mode between game and ui and just game as the player character moves in and out of the box.

then positioned that overlap collision box component to be just in front of the BP_Screen static mesh with the 3d widget on it

[brazen stirrup]

yeah one sec

widget bp:

[broken wadi]

So as they walk up it does the overlap and changes input mode so they can interact with the widget while still having character inputs

[brazen stirrup]

level bp :

[broken wadi]

You've already confirmed the widget is working normally when its 2d? All the hovers and button clicks etc?

And there's nothing else in between the character and the 3D widget? No blocking volumes or anything like that?

[brazen stirrup]

one sec

yes

this is the bp btw

[broken wadi]

You're disabling collision but perhaps you want to use Query Only (no physics collision) instead?

[brazen stirrup]

yup

well im not disabling collision

[broken wadi]

on the screenshot you are disabling it on the entire actor and the widget

[brazen stirrup]

oh

wait

sorry i have someone workig on this project with me

yup that was the issue

thank you man!

[lime crow]

can i use to event fires or will this break stuff?

[hard sinew]

can somebody just tell if how the hell to fix this nonesense

ive been struggling on it for more than a day now

[kind estuary]

Im making a game that is like a battle of orbs.
Some orbs attack with spears, others arrows, others attack with spears and arrows, others swords.
You know.
How should i manage this? I have all the orbs in a data table.

I can make if statements and spawn an attack component that each specific orb has

[wild pumice]

My Event Begin play on my Character Base creates a HUD widget and adds to viewport. The problem is I have Child actors of this player class that are also creating duplicate HUDs. Is there a way to limit this from running on the child classes?

[autumn pulsar]

kind of a vague question asking how you're going to program your entire game. I wouldn't do if statements for that

[wild pumice]

Also, is it online? Thats a whole nother can of worms.

[autumn pulsar]

are the child actors other players or

[wild pumice]

The Child actors are Characters the Player can switch to real time.

[autumn pulsar]

can probably check if they're possed by player 0

then have an onposses event clear the old widget or so

[wild pumice]

I'll try that

[warm hare]

Why is my gate not staying on tack when interacting?

[kind estuary]

what would you do?

its important to know because i saw some stuff saying to create components for each attack type

or other alternaitve would be a GAS system.

But since this is an RTSish game, idk

[kind estuary]

you are changing the Y and the X it seems

its at 0 , 0

Make Vector set the X and the Y properly

though not sure

[warm hare]

Doh! Thank you. I put the right values in. Appreciate you

[autumn pulsar]

RTS is pretty ambitious for a first game

You'll need to deal with object pooling for any semblance of performance

[wild pumice]

I need to set an object reference to the Game Mode's Default Pawn class. How do I do this? nothing I'm trying seems to work.

[hushed fox]

You could just make a parent class that has all the different types then enable it with a enum or integer for the child classes.

Or if you are wanting to set weapons per type you could use a dictionary map as an alternative to a large switch statement.

[autumn pulsar]

What does the "half size" in the box trace do?

[autumn pulsar]

[wild pumice]

Thanks

[kind estuary]

Np king. good luck

[kind estuary]

🫡 cheers

[kind estuary]

what about a GAS 💨 system? Maybe its not worth it

[autumn pulsar]

if I run an event twice on the same frame with different inputs, how does Unreal handle it?

[hushed fox]

I’m not sure, I’ve never used it. Seems complicated and you could just make your own framework built around your project needs

[hushed fox]

I’m pretty sure it just does it twice, the engine can handle more than one execution a frame.

[autumn pulsar]

is Box Overlaps Actors AABB?

I don't seem to be able to orient it hmm

[autumn pulsar]

Cannot construct objects of type '/Script/Engine.PrimitiveComponent' in Construct Object from Class

I'm trying to essentially spawn a box/sphere/capsule I can use to see if I impacted something

The Overlap functions don't support orientation of the shape

and I don't need to run a trace since i'm just testing a shape

Would trace really be my best bet?

[maiden wadi]

It will just run both like Blox said. Your executions cannot be cut off in the middle of a frame. If you put too many things in a single frame, it will simply extend the frame's time. This is how you get low framerate in games with bad optimization, you end up with too much stuff running per frame.

[maiden wadi]

@kind estuary
GAS isn't really that complicated. It has four basic components.

Abilities do things, they're the actions of your system. They are the FireWeapon which spawns projectiles like bullets or grenades or does line traces directly to apply effects.

Effects are definitions of... effects. They contain attribute manipulations, and associated cues. You apply these as instant manipulations to attributes like an explosion. Or you apply one for a duration which applies attribute modifications every set time like a regeneration effect.

Attributes are just that, defined floats. (These come with the minor downside that they require C++ unless you use the GAS assisitant or helper plugin thing. But you can use a ton of GAS even without relying on attributes as well.)

And last are Cues. Cues are visual and sounds. You can associate a cue with an Effect to play along with it like keeping a regeneration particle going. Or you can execute them as one offs from abilities like a muzzle flash.

You're going to find that you're going to do all of these things if you make your own system as well so there's not really a lot of reason not to learn and use GAS in the end for most projects.

[kind estuary]

yeah 💯 i will use GAS if not to become better at it. I followed a tut of Ryan Loley a while, it was nice, but it was complicated, and it was in blueprints. But left my with the feeling it was useful because of how modular it was.
But i forgot all of it by now, so i have to see it again 😵

The other thing that worries me is that my characters are UObject, not AActor.

And then they have a reference to the instance mesh

This is better but its uncommon

[maiden wadi]

Why not just base them on AActor? Why UObject specifically? As a UObject they have to be based on some other actor anyhow for replication if you ever go to multiplayer. And there's only like a 100byte difference between an AActor and UObject class. which is not really a lot for the added functionality and ability to be compositional.

[gentle urchin]

Iirc correctly i saw a rather significant gain moving from aactor to uobject

If you have a large amount of things that require some Ecs-esque system, surely you wouldnt want to try and replicate them as normal aactors but use some replication manager instead

[foggy spire]

how do i access a replicated object variable from an actor that is not locally controlled?

[maiden wadi]

Depends on the thing in question. Most systems won't see much of a difference and should get more performance out of an actor based system unless you're causing something like too many actors running networking stuff. In which case you're probably already at a number where you should be considering a real ECS system like Mass or FLECS which won't use UObjects for anything more than static data like fragments.

[maiden wadi]

Need more context. What is the object? What does locally controlled have to do with it?

[foggy spire]

(its replicated)the variable is an array of actors, and for each of them i want to change the color of their mesh material, suppose i have a 2 player listen server setup, from the client i want to change the material of the actors in its array and i also want to change the material of the actors in the other players array, in the server it works just fine, but in the client when i try to change the material of the actors in the array of the server player/ the the non locally controlled players, it gives an error, and it detects the actors in the array as invalid, okay i will show a video

[maiden wadi]

I realized I didn't actually explain that. 😅 Actor based systems benefit from being culled network wise. Meaning you aren't always replicating to the client. Network manager systems basically encompass a system or area in a sense, and normally always replicate everything. So if you're doing 200 actors that are spread so far out that a player is only going to see max 20 of these at a time, you're wasting resources replicating the other 180 at all times when only 20 are relevant.

And there is something to be said that of course replicating smaller things allows for more, but again at that point you're complicating your implementations enough that you should just consider a real ECS system because chances are you're going to hit walls fast with any non ECS system, and unless you're already finished with the shipped product, it's going to get extended, which means a lot more than that initial 200 projection.

[lost hemlock]

Im only interacting with this wooden log once in my game

and once I do

I wanna destroy this macro/[function] completelly

but you can't destroy a macro/function

how can I destroy this piece of code after I destroy the first wooden_log_BP?

[gentle urchin]

Glad im not planning on replicating my 5k 🤣

[trim matrix]

Question about AI optimizing method in Unreal Engine 5 with Blueprints only:

Method One: I will use normal Enemy AIs with NavMesh, Number of AI is 60, move to the location (There is Another AI types also)

Method Two: I will add spline to a actor spawner, I will spawn AI, give them simple functionality same as Method One, No NavMesh, I will move them with Timeline, when enemy goes to next point of spline, that event is called again and AI goes to next point with timeline again. Enemy AI number is 60 again

Which will be performant? My friends told me that you are tick, for moving the AI with timeline, and choose method 1

[gentle urchin]

Theyll both tick for movement. Theres a bunch of caveats and issues here tho

There could be written an entire diary of the different issues both methods will bring about. For the actual result you'd need to profile the final implementation as that will matter a lot on how performant it is

[kind estuary]

I didnt know this. They are stored in a manager of soldiers. Which is an actor. So that will work? Im not thinking of multiplayer, but its good to know these things. I thought UObject was replicated too.

I like UObject, is like simple and clean

AActor has lots of stuff

https://forums.unrealengine.com/t/best-practice-actor-vs-actor-component-for-temporary-logic/129481/12

here they are saying that Actor has 9k lines vs Component 3k lines

UObject works great for me because they dont need to tick, or anything just data

And it also supports functions

The only thing that sucks is the multiplayer

[gentle urchin]

It doesnt suck its just some extra work to set it up

component != uobject aswel, but that you already knew

[maiden wadi]

The amount of lines in a class doesn't matter. A class can have ten million lines of code and still only take up four bytes with a single float value in it and cost nothing at runtime if none of those functions are running.

The functions of a class do not get "copied" or carry anything with each instance. Every instance shares those functions so having one or fifty instances makes no difference for how many lines of code it contains. The only thing that matters as far as instances being cheaper in the end is how much code is being ran each frame and how many properties the class has which take up actual memory space.

[normal raft]

hey .. been pulling your hair out with camera movement behaving weirdly no matter what you do .. followed 4000 tutorials .. asked every one every where.. spent hours and hours fiddling around in spring arm and camera settings ...here a top tip ... Goto that Piece of shit corrupted up Springarm Delete .. re-attach the camera be happy.. I suspect the spring arm might get dirty as my original template was built quiet a few versions back .. but something was defo messed up with mine as it wouldnt follow yaw oribit correctly all the way through 360degrees

[blissful horizon]

Hi guys, does anyone knows anything about how to copy files from one directory to another using BP nodes only? I think I might have one (or both) incorrect input string?
Both the file and the target directory exists, I checked during execution
thank you in advance :)

[normal raft]

not sure if you should be using / unless its linux but just worth mentioning does getparent content directory actually return with slashed ?

[blissful horizon]

@normal raft yes it does, I am checking if the file exist with the branch before execute copy file

it executes, but return a fals output so the file is not copied (I have checked it is not there)

[dark drum]

I think you need to use back slashes in the path. Also, I think you need to include one at the beginning of what you append as getting the content directory wont have one on the end.

If you've printed the paths and they are correct, it could be a permissions issue.

[blissful horizon]

this is the current output of the strings used

@dark drum @normal raft thank you I try that quickly see if it helps

[dark drum]

Oh... There's spaces in the path. It could be that that's throwing it off.

[blissful horizon]

same result with backslashes :(

[blissful horizon]

I thought of that too, but in that case it wouldnt find the file at all? I will test it quickly

[dark drum]

Hard to say, you could try replacing the spaces in the path with '%20' and see if that works.

Of course it depends how the functions are setup to handle the spaces. There's no guarantee that both handle them lol.

[normal raft]

heh

[dark drum]

Another cause might be that the copy file node requires the folder destination to exist. Not used it so can't confirm but if it doesn't exist, you can try the create directory node first to create the destination folder before calling the copy.

[blissful horizon]

still no good :(
there is a folder destination, I also checked that

[split dagger]

Why are you trying to copy a sav file?

[blissful horizon]

it is triggering and executed through

[split dagger]

Could you load the .sav file and just save it again with a different name?

[blissful horizon]

I want to add my save file to the default save file in the shipped build

it need to be in the default save folder so I can load the map

@split dagger

[indigo abyss]

Sorry I don't want to interrupt but is there someone who would be able to help me resolve an issue with Floating Pawn Movement?

[little moat]

Shouldn't this work for getting an actors direction?

[blissful horizon]

only if it moves straight forward

[little moat]

Yeah it does

I'm thinking of how to know if I need to have my AI calculate avoidance

[normal raft]

how can smoothly restore my spring arm after releasing the key for go forward .. I tried with Lerp but it didnt seem to work quiet how i expected ... but i wouldnt mind using a timeline though it dosnt seem to offer me a node for this?

this is in a macro so might be why it wont give us the node

[pulsar axle]

I've bug fixed and bug tested so much I've actually found bugs in unreal's code instead of my own

[maiden wadi]

Which ones?

[maiden wadi]

Don't worry about interrupting. It's a public social space. Usually just post a question with your issue laid out as well as you can and if someone can help, they will try.

[pulsar axle]

For some completely unknown reason, one of the components in my mesh refuses to move.

yes I've checked the moveability settings.

despite it being a part of a blueprint instance, it refuses to move with the rest of the instance when the game is running, even by simply moving it manually when simulating.

[maiden wadi]

Any chance you're affecting it on tick somewhere?

[pulsar axle]

demonstration

[dark drum]

What supposed to move that isn't? The green arrow?

[pulsar axle]

everything in my code comes out of the Event-Begin-Play node, so it's only executed once

[pulsar axle]

You can see the outline around the room I am moving, the same outline is also around the arrow, meaning they belong to the same blueprint instance and thus should be moved together.

[dark drum]

Ok, I'd say you've set it's location to absolute instead of local.

[pulsar axle]

using code to move the arrow ofc also doesn't work, it's fixed in place no matter what for some reason.

Please understand I have simplified ALL my code has been reduced to simply spawning a room in the position of the chosen arrow, I couldn't get more simple, that's how far down the debugging has gotten lmao

[pulsar axle]

interesting, I'll look into what that means

[dark drum]

Select the component and in the details panel, next to the location, you can specify if it's local or absolute. Local means it's local to the actor it's in, absolute means it's based on the world. (something like that anyway)

If you use absolute you can move the actor and the component will stay in place. I've used it a few times lol.

[pulsar axle]

here?

[dark drum]

Yea, click where it says location with the little down arrow.

[pulsar axle]

Nah it's still remaining in the same place

[dark drum]

is the component used anywhere? You can do a search.

[pulsar axle]

OH

I just discovered something!

Somehow, someway, the arrow is being removed from the default scene route

but-
I have no code that could even do this? at least none that is set up right this moment.

as you can see, before simulating the game, the arrow is in the correct position

[pulsar axle]

full breakdown with my voice here @dark drum

[dark drum]

Oh, so it's being detached from the scene component. Tis odd.

[normal raft]

man y epic do you have to make every thing so ugly

the epic dev that thinks that new time stuff on the timelines is perfectly fine wants thumping

[dark drum]

If you unhook begin play, does it still detach?

[pulsar axle]

It's not going to spawn anything if I unhook begin play though... they are all spawned using it, the world is empty prior to using it

[dark drum]

Oh wait, you've shown logic in a different thing. What logic do you have in the rooms that actually have the arrow in them?

[pulsar axle]

OH

BUG

AttachTo: '/Game/VRTemplate/Maps/UEDPIE_0_VRTemplateMap.VRTemplateMap:PersistentLevel.Dungeon_Starter_Room_C_0.Overlap Folder' is not static (in blueprint "Dungeon_Starter_Room"), cannot attach '/Game/VRTemplate/Maps/UEDPIE_0_VRTemplateMap.VRTemplateMap:PersistentLevel.Dungeon_Starter_Room_C_0.OverlapBox1' which is static to it. Aborting.

FIXED

just needed to make all the scenes static

[autumn pulsar]

Does an actor component tick tick independently of the actor or with the actor?

[wild pumice]

I am current using Set View with Target Blend to switch between my characters. Is there a way to keep the rotation the camera is facing when switching? It always resets to the camera's default position on the character.

[dusky cobalt]

Save the Current Camera Rotation when switching and set the new one as the one you just set?

[wild pumice]

any idea what node to use? Set Control Rotation isn't working.

[gentle urchin]

Id suggest overriding the cameramanager 😄

But i guess you can set the rotation of the target actors camera to match the source camera

[pale flame]

I have a grid system that players can buy stuff and then place it on a grid spot. I want to be able to have a fence (which is already able to be bought) but I want to be able to place down a whole enclosure at the same time. I've tried a few things that didn't work at all. Could anyone point me to some resources that could help me along with this?

[kind willow]

Is there a way to get actor's default value of a variable inherited from a parent?

[graceful gust]

When I pause the game, the countdown timer keeps going.

[kind willow]

Where is the timer stored?

[graceful gust]

Widget

[kind willow]

Try looking for a "Set Tickable when Paused" node

some things can still tick under pause, this should toggle it

[graceful gust]

Where do i connect the target?

[dark drum]

Get the class of the parent and use the get class defaults node.

[kind willow]

That gives me the default value of the parent

[kind willow]

The actor you want to toggle

[graceful gust]

The timer is stored in the widget

[dark drum]

Is that not what you asked for?

[kind willow]

No. I need the value that child blueprint uses

I need the left one

[graceful gust]

Says that the blueprint (self) is not an actor

[kind willow]

Hm, maybe try plugging it into the owner?

[graceful gust]

So when the timer is in the widget, do i have to move it elsewhere?

[kind willow]

That'd probably be for the best, unless the timer is for an animation or such. Let me look a bit deeper

[dark drum]

You can just use the get class default node, just plug in the class you want it for, whether it's a child or parent.

[kind willow]

I already tried that. It will give the master class defaults

so, in my example, it'd output "100" in the health float

even if the class it uses has it set to 30

[dark drum]

How are you setting it to 30? Modified per instance in the level?

[kind willow]

No, I go into the actor details and change it there

although, important to mention, the code runs inside the master actor

since each NPC needs it's health value stored for later, the master runs it on begin play

[graceful gust]

I need to cast to the widget from an actor

Where do i connect object?

Ah, i think i remembered

[autumn pulsar]

can I make a map but the secondary value is an array?

[kind willow]

no

would be nice though

[autumn pulsar]

I guess I have to make a struct that's just an array

[dark drum]

Can you show what you mean?

[kind willow]

Not really I'm afraid. All I'm doing is MaxHealth == CurrentHealth inside the master

This is what I'm doing right now, just make sure the value is cloned only when the actoir ran for the first time

Because otherwise the value would be cloned every time the player loads the game, so a dead enemy would clone a value of 0

[dark drum]

So your setting the max health to the health value, health being the variable you change in the details panel?

[kind willow]

Yes

[dusky cobalt]

isn't Has Ran Already checkd true by default?

[kind willow]

no. I just added it. This is an alternative to getting the default value

Originally there was no branch

[dark drum]

I'm not sure why the get class default wouldn't work then. 🤷

Maybe a 5.3 bug?

[dusky cobalt]

can you show screenshot in the editor of the default value? also you can add breakpoints and see if this code is even firing

[kind willow]

I did here

[dusky cobalt]

click on set max health node and add breakpoint

[kind willow]

the left is child, right is master

[kind willow]

it fires just fine, that's not the issue

just ignore the branch, it was added as a band-aid solution

[dusky cobalt]

ok so you are setting Max Health from Health variable right
are you doing this on begin play in the master class?

[kind willow]

yes. The issue is that it runs every time a game is loaded, so if the enemy got hurt, the variable will be set to whatever the current health value is

[jolly obsidian]

I made this code to grab item, but it's not working, I've tried a few things, I've checked everything and nothing, does anyone know what it could be?

[dusky cobalt]

do you mean when you load like 2nd lvl or what is the situation that this ''enemy'' is ever loaded again?

do you spawn this actor second time?

[kind willow]

This looks to complex to debug from just pictures. You gotta get some prints and breakpoint to narrow down the issue first

[kind willow]

If I save the game, then load the save

F5 -> F9

[dark drum]

Would it not make sense to have the health set to max health instead? Then if your loading saved health it would override the health value without affecting the max health.

[kind willow]

Then the enemy would heal every time the game is loaded

[dusky cobalt]

where is the ''enemy'' respawned first time?

[kind willow]

It is not respawned. The entire level gets reloaded on game load

[dusky cobalt]

ugh

[kind willow]

and so all actors are spawned again

[dusky cobalt]

so how do you save and load data? and why are you not saving the current health when doing save?

[kind willow]

I do save the current health! That's the issue. The value gets loaded then overrides the max health

[dark drum]

You would save their current health and reapply it. If there's not saved health to apply set to max health.

[dusky cobalt]

okay, so you are saving it somewhere where we can access it?

[kind willow]

Yes, the actor itself

[kind willow]

That's what the boolean does. I hoped I wouldn't need it though and I could get the default value instead

Which it seems I cant

[dusky cobalt]

but we dont see where you are saving it first and it doesnt looks like it gets loaded?

if its just on begin play then it happens on begin play

[dark drum]

OnBeginPlay -> Does save game exist -> if true, load saved game and apply health. If not set health to max health.

It seems odd that your setting max health to the current health at any point.

[dusky cobalt]

I feel like you just need to delete this part from begin play and make:

Create Custom Event
Initialize Enemy > Set Max Health from Health

This you go somewhere to level blueprint for example (or create new BP_EnemySpawner / BP_EnemyManager w/e)

There on begin play you Spawn Actor from class, after you spawn it you Initialize Data.

If it's only one enemy, then on begin play you check if this actor that was created exists, if exists already then you don't spawn it.

[dusky cobalt]

or you need something like this

like you are missing step to ''avoid'' begin play on your actor that you are trying to load

[jolly obsidian]

After resolving some things with the break points, I arrived at this: the code runs entirely until the last breakpoint, but the object doesn't move the right way

When I hold the mouse on it it goes up, and when I release it it goes down, but it doesn't move or anything

[dusky cobalt]

mostly these branch checks seems very off and also what is this function that checks if able to grab but doesn't give anything back? if something makes ''check'' then it should provide info back, either doesnt matter what it does unless you want it to do something at this point (change color for example)

also if you want to grab something and then be able to move it ''live'' you might need to put something on tick or timer by event, the rest ''more or less'' makes sense, but you would need to describe how it exactly should work

[jolly obsidian]

Give me a second, I have an example of +- how it should work

[split dagger]

A little boolean in your event tick so it only moves the actor when the boolean is set.

[dusky cobalt]

also maybe disable collision first and then grab component

[kind estuary]

🫡 thanks i didnt know that. so why do the pros of unreal always recommend using uobject when possible? Id rather use Actor, but i thought i was being better doing this way.

i mean there must be a reason, right ?

[ocean gate]

Hi! Does anyone know why "Set members <struct name>" does not have any input except for the struct reference itself? In all posts I find online people usually have an input from the struct they're modifying such as an int or float or whatever?

[jolly obsidian]

It was supposed to work like this, but I made the new code from scratch, because I'm making a system of parts and bolts, and I decided to do it from scratch to make it better, but the idea would be this

[jolly obsidian]

I'll try that for a second

[dusky cobalt]

is this box actor or component? print if it actually hit the component (name of it), also you are disabling collision of the actor and not the component, also not sure what does this do

[split dagger]

try right clicking that when it's not connected. where it says "struct ref"

[ocean gate]

AH restore all structure pins fixed it! Thank you so much! :D

[autumn pulsar]

Any ideas why my MultiBoxTraceForObjects is hitting the same actor multiple times in a single trace? https://i.imgur.com/CbhJ1jK.png

[dusky cobalt]

click on "set members node" and on the right you need to ''tick'' the pins that you want to set

[dusky cobalt]

how are you checking that?

[autumn pulsar]

wdym?

[dusky cobalt]

how are you checking that actor got hit multiple times and not once?

[autumn pulsar]

for each loop

https://i.imgur.com/ejrJF1q.png

keeps adding the same actor to the array

[split dagger]

You're welcome! Glad I could help.

[dusky cobalt]

probably you need to clear array before you ''cast'' trace, that's one thing, and 2nd thing you can use add unique so it won't add the same actor 5 times

does it add actor 5 times on 1 hit?

[autumn pulsar]

I could just discard the multiple hits, but I'm wondering why it's even hitting the same actor multiple times in a single trace

[dusky cobalt]

also you actually saved ''hits'' and for each ''hit'' you add the actor that was hit (once)

[autumn pulsar]

since it should be 1 actor per hit

unless I'm just not understanding how shape traces are designed to work

[dusky cobalt]

so if sphere/box registeres that it hit actor in 10 places, you get 10 for each loops that add the same actor 10 times

just use add unique when you are adding actor to the array

[autumn pulsar]

https://i.imgur.com/KAqJeQz.png

so if I do a trace, is this 1 hit or 5 hits?

[jolly obsidian]

I think I found a solution, I don't know if it's the best, but I think it works, it's what I did in the old code, a simple loop

[dusky cobalt]

probably 5

[dusky cobalt]

you can use Set Event by timer and just use 0.04, it's less costly but will work almost the same (adjust the time so it feels good)

and also you can toogle this timer on/off

[jolly obsidian]

I think I'm going to do something that checks that I want to get an item and if I go to get the item the timer starts, it's a solution to make it less expensive too

[autumn pulsar]

is INDEX_NONE -1?

[dusky cobalt]

just try with add unique here

[autumn pulsar]

yes I am

[dusky cobalt]

Start Event timer after grab something = true, release clear and invalidate

[autumn pulsar]

but I need to know if there was a collision

and it's supposed to return index_none if there is

[dusky cobalt]

but you already checking that?

[jolly obsidian]

exact, but anyway, thanks man

[autumn pulsar]

I have logic behind I need to branch

https://i.imgur.com/OtSZWaa.png

basically need to do nothing if it's something I already hit

[jolly obsidian]

Now I just make some adjustments to make the movement cleaner, but it looks good to me

[dusky cobalt]

need more context

[autumn pulsar]

I mean I got it working, I was just explaining it

[lyric island]

i have this scenecapture2d thats positioned really high up in the world and when i look at the contents of it, everything is extremely low res and jagged. the resolution of the render texture im using is 1920x1080 but it's still really really ugly. any way to improve the resolution or work arounds?

[autumn pulsar]

https://i.imgur.com/4ZSRqdv.png

[dusky cobalt]

this will kind of never be true so its weird how you are checking it

[autumn pulsar]

I have a trace

and it was hitting the same actor multiple times

so when I was iterating through the actors I hit, I kept running into the same actor, and applying damage multiple times

so I needed a way to add it to the pool, and discard it if it appears again in the same hit

[dusky cobalt]

yea because you were adding for each hit, the same actor, by changing it to unique this actor will get added only once, because on 2nd iteration of loop he is already in the array

so even if it gets hit 10 times it gets added to once

[autumn pulsar]

well yes, but the logic after it would still run

while he'd only be added to the array once, the damage calculation step would still run

[dusky cobalt]

this is your problem

you should Deal damage to all actors hit

(unique actors)

but this you do on complete for loop

so on Complete, you take Hit Actors array, For Each Loop on that array and Deal Damage

[autumn pulsar]

Okay, now I'm picking up what you're putting down

well

actually that wouldn't work

[dusky cobalt]

First Loop you check actors hit by hitbox, it adds them to the Hit Actors, then you take Hit Actor Array, and for each Deal Damage

[autumn pulsar]

That wouldn't quite work, because a subsequent hitbox would hit the actors, and I'd then be doing damage to an actor that already previously took damage

[faint pasture]

a multi line trace would be 3 hits

or 5

depending on the normals of those faces

[autumn pulsar]

okay, so it can hit the same actor multiple times

[dusky cobalt]

Do you even read what I write to you 😄

[faint pasture]

Not 100% sure, test it. Probably with multi line trace I'm guessing

[dusky cobalt]

It can even hit the actor 500 times, what is the problem if you add him only once?

[autumn pulsar]

yes, I think you're missing context

[autumn pulsar]

I get that, it just wouldn't work for what I'm doing

https://i.imgur.com/qPt005O.png

[dusky cobalt]

How it wouldn't work?

[autumn pulsar]

I'm spawning hurtboxes over time

[faint pasture]

then add them over time

begin -> clear array

[dusky cobalt]

yeah you also forgot to clear the array before first for each loop

so it's clear, looks for hits, looks for actors

[faint pasture]

If you want the hits to happen over time then you'll need 2 arrays

HitThisFrame vs HitThisAttack

[autumn pulsar]

I'm using the array to make sure actor 1 doesn't get hurt by the same sweep agaain

[autumn pulsar]

kind of what I'm doing by just branching off the add unique

[faint pasture]

Do you want damage to occur on first hit or at end of anim?

[jolly obsidian]

Is there any way I can make an object only collide with certain objects?

[radiant talon]

Hey I have a issue with sliding down a slope. Im trying to have it realistic when going down it curves. Let me know if this is possible with this thanks!

[faint pasture]

The collision channels isn't enough?

what are you actually trying to do

[faint pasture]

Just rip all the trig out and use vectors

[jolly obsidian]

Sorry, I already solved it, I had done something wrong

[autumn pulsar]

I'm using it further upstream to ignore the hit actors when I trace again

[faint pasture]

You can do it with one array like this

Start -> Clear array
Hit -> if thing not in array, damage it and add to array

This would be most elegant and work for hits over time and just 1 hitbox

[autumn pulsar]

actually

[faint pasture]

I'd use a set if there's a possibility for a lot of hits

set.contains is dummy fast

[autumn pulsar]

that's basically exactly what I'm doing

[faint pasture]

so what's the problem?

[autumn pulsar]

I was initially confused why my trace was returning the same object multiple times

then it kind of became a discussion of implementation

I don't clear the array because it's a local variable and gets destroyed on function exit

[faint pasture]

You'll want an array that lives for the entire animation time

[autumn pulsar]

I have a map that does that

[faint pasture]

what is your attack, an anim montage?

[autumn pulsar]

https://i.imgur.com/XPI4ZUu.png

[autumn pulsar]

yeah

basically, my actor has a pool of active hurtboxes

and I use animation events to add and remove active hitboxes to a pool

[faint pasture]

you need a set that is cleared when you start the montage and per tick of anim, you damage and add to set anything that's not in set

unless you intend for 1 montage to hit a thing multiple times

[autumn pulsar]

https://i.imgur.com/L4zlod6.png

Then I have an animation notify state

https://i.imgur.com/ZZKEuG2.png

[faint pasture]

Where is the bit where you damage an actor

[autumn pulsar]

Basically,
Animation Plays -> Add hitbox with name -> Adds hitbox name to active pool on actor
Tick -> Check each Hurtbox in the Pool -> Spawn the hurtbox and test for actors inside -> Run through the list of actors, if we haven't hit them before, add them to a list and then do damage to them -> Add all the actors we hit to the ignore map per hitbox and then loop

[faint pasture]

When does the ignore map get cleared?

[autumn pulsar]

The animation is a notify state, so when it ends it removes the hitbox from the pool

I added a clear event I plan to run when an animation gets interrupted or so
