Player rotation vs target direction

[fickle lichen]

Ah

[gentle urchin]

Is it even remotely possible that we can see this target?

[fickle lichen]

wdym

[gentle urchin]

Thats the question the dot product would answer

So youd do something like;

Float DotProduct = GetAcrorForwardVector().Dot(GetActorLocation(), Targetlocation);

if (DotProduct >= ViewTreshold)
{
// I Might be able to see this target
}

[fickle lichen]

How could I covert a player FOV to a ViewThreshold?

[gentle urchin]

Personally im not sure id even bother

Raises a ton of questions

Figure out the view treshold for some ultra wide and call it a day is prob what I'd do

[fickle lichen]

Just consulted with a friend; it's cos(angle / 2)

[gentle urchin]

So players with bigger FOV settings get an advantage

[fickle lichen]

Well the FOV is set

But I might change it at some point in development

[gentle urchin]

Fair enough

[half pollen]

Is there any public API for getting visual property data of every blueprint nodes?
I wanted to make something similar to blueprintue.com but for a different app, as a plugin.

[fickle lichen]

Is pawn control rotation synced to the server?

Obviously the server needs to know where the player is facing for this to work

[fiery swallow]

assuming you're using the default method for moving and rotating in unreal engine then yes it's replicated out of the box

if you manually set the actors rotation on the client I'm pretty sure you could cause your own rotation to go out of sync

Before spawning, get the datatable. GetDataTableRowNames. Get a random int in range of 0 to the name array's last index. Use that int to get the name in the array, use that datatable row to spawn.

[mild galleon]

Hello and good morning.
I have an issue with combo boxes. I add options from data table row name, but it crashes the game. i have a more detailed description here: https://forums.unrealengine.com/t/combo-box-loaded-options-from-data-table-row-names-but-crashes-game/1984071
If anyone knows about the issue, potentially, please let me know, very appreciated.

[half pollen]

anyone? 😭

[frosty heron]

Why bother? Is there even money in doing it?

Unreal is pretty bad when it comes to documentation I wouldn't bother

Generated one*

[half pollen]

i was planning to make an obsidian plugin to keep some nodes in the vault 🥺

[frosty heron]

No idea what those are

[half pollen]

obsidian is markdown note taking app

[maiden wadi]

This is an impossible question to answer without a crash report.

[mild galleon]

i can attach the crash report

[mild galleon]

thank you, will do

[dawn gazelle]

You're probably getting into an infinite loop scenario. You're using the bind event for when a widget is added to the combo box to then add more to that same combo box, which then means each time you're adding something, it's adding the entire contents of your data table again, and for each of those adding the entire contents of your data table contents again, and for each of those.... etc.

[mild galleon]

thats one of the 2 scenarios,

the other one is

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\SlateCore\Public\Layout\ChildrenBase.h] [Line: 210] The FChildren is destroyed. You probably have 1 widget owned by 2 different FChildren.

[hardy merlin]

Hello. Does unreal have a system like delegates except you dont need to bind to an individual object? Something like a Global Event. For instance, if I want to know if any character on the map touched another.

[fiery swallow]

You can create that yourself, I've seen quite a few of those available on the marketplace

[hardy merlin]

Is there a search term for viewing marketplace solutions?

[fiery swallow]

but afaik unreal engine doesn't have that built in

[mild galleon]

there was something like broadcasting events, what was it called.
There were 3 types of BP interactions, via interface, via ... sorry forgot the name

[dawn gazelle]

Do your foreach loop to add items in the OnConstruct event of the widget, and delete that binding.

[hardy merlin]

Direct calls, interface, and binding require knowing the specific actor.

I'm looking for a system where there's a designated shared object, like a subsystem.

[mild galleon]

https://dev.epicgames.com/community/learning/courses/LWv/unreal-engine-blueprint-communication/b7yv/unreal-engine-event-dispatchers

event dispatchers, i think that was it

[dawn gazelle]

There's nothing built in like that. Lyra has an example messaging system where you can broadcast a message and have things listen to certain channels (gameplaytags) and respond to such events.

[mild galleon]

its global

[hardy merlin]

Those are per-object instance.

[hardy merlin]

Messaging! That sounds like what I need. Thanks. I even have Lyra installed.

[dawn gazelle]

Let you do something like this. The message is a custom structure of your choosing.

[mild galleon]

great ! thank you for your help! IT WORKS

🙂

[hardy merlin]

I see now. Do I just copy the entire subsystem plugin over to my project or is there another way to get it?

I'm building through C++

[dawn gazelle]

I believe this outlines what you need to do.
https://github.com/imnazake/gameplay-message-router

I kind of recall having to add AsyncMixin too or something

[hardy merlin]

This is exactly what I needed. Thank you! It even has templatized message content.

[river hill]

hey i this will only take a quick sec but how do i recall a custom event

ive got this custom event

but i cannot find the red box for it

where do i find it

[gentle urchin]

Its a keyboard input

Space key

[river hill]

no no

i want the custom event that goes with this that ive created

but i cant find it

i deleted it and want it back

[gentle urchin]

Double click it ?

[dawn gazelle]

You've converted it to a function. You'd have to delete the function, delete any calls to it, then recreate it as an event.

[gentle urchin]

Isnt there a convert to event option

[dawn gazelle]

Oh so there is

[river hill]

the old one still exists somewhere

[ionic cypress]

I suggest using ability system to avoid most of server client action syncing problem...

[fiery swallow]

just double click, on the server jump node and it should take you to exactly where the other one

and then delete it

[crisp moon]

doing like this ok or not ?

[gentle urchin]

If it fits your needs, sure

Started is prob better to use

[deep geyser]

Does anyone know if I can use Packed Level with blueprints inside of it? I am working on a assembly line digital twin and there is some nesting happening in their that can't be avoided, since there is dependencies on what is moving around. Can I pack a level with my hierarchy of BPs and be able to use it in my main level, where I would have my full assembly line setup?

[gentle urchin]

I believe so, but havn't tried it yet personally

[sand bloom]

yeah I did that and rebuild it in visualstudio but that just stopped me from being able to open unreal engine lol because it complained about modules. I don't think c++ is for me

Appreciate the help though

I'll try a uobject first as a alternative maybe or just a master object with all the variables I need and children changing said variables

[frosty heron]

That's a shame if you chose to use Unreal trial version

[hoary sky]

Hey Folks is it alright to ask questions here?

[gentle urchin]

yes

dont ask to ask ^^

[echo storm]

How can I add/remove levels from my persistent level using BP?

[sudden sedge]

Hello all! Was wondering if anyone had tips on switching IMCs in-game. I have a setup where i switch between 2 characters. Everything works fine with switching the mesh and ABP, but for some reason the IMC only switches once and then doesn't switch back, even though I have essentially the same code for switching to each character

[quasi steppe]

when I start the game as a client I get an error as not found but when I start the game as a server it is found what could be the reason for this (in bfl)

[fiery swallow]

Anything at the 0 index is usually not the same as for everyone, also beginplay is not a very reliable time to retrieve information

So player at 0 index for server may very well be player at index 3 for a client

But your problem might also stem from the fact that you're trying to retrieve a reference to something on beginplay which may not have initialized yet

Try getting a more direct reference to whatever holds that component, and also maybe try getting it a few seconds after beginplay

[quasi steppe]

That's what I was guessing, I wanted to make sure. Thanks.

[raven gyro]

is there a better way to turn on 1 boolean and turn off the other 10 boolean in an array at the same time?

set array elem can only let me turn on 1 in the array, but idk how to turn off the other 10 D:

[maiden wadi]

What is your use case for this? Initially you can simply select an index, store it in a local var, loop and turn them all all, and after the loop turn the one on.

[raven gyro]

i have an event tick going, and each button trigger something, i only want it to tick when that button is click and everything else must be off

oh thats a good idea let me try 😄 thanks authaer

[maiden wadi]

Generally I would ask why you need to switch IMCs? They're both characters. Use the same control sets for both? Or just add both IMCs at the beginning and leave them on. You can only possess one pawn at a time.

If you're not using possession and this is some sort of input layering, one thing I'll note is that you've never removed the old IMC of the other character by the looks of it. So it can't really be readded, as it's already there.

[manic vessel]

I seem unable to manipulate this spline added here. like if I had added from the components dropdown. whats the trick?

[cyan spire]

Hello i have a question. When using soft references stored in a DataAsset, is it better to make a soft ref out of the Data Asset or out the Contents? So for example i have a Melee, Equip, Dequip, Sound and Model DataAsset that i access in runtime, is it smarter to resolve the soft ref for the asset itself or for the content?

[manic vessel]

Example top spline is added via the components drop down and I can selet it, I cant even select the spline added with the node?

[cyan spire]

Because i don't understand if its needed to copy paste the same async load node 3x over and over again if i only need 3 out of the 10 vars.

[chilly stump]

hi guys im new in Unreal engine, I made a floor and when we get to that floor, the cube starts spawning. I'm trying to make fit Object pool for it, but I couldn't solve this error. Can you help me?

when i start and pause game (after 2-3 sec) i can see my pool but after that they are disappearing

Blueprint Runtime Error: "Attempted to access BP_ProjecTileCUBE_C_0 via property CallFunc_Array_Get_Item, but BP_ProjecTileCUBE_C_0 is not valid (pending kill or garbage)".

[crisp moon]

i want to make stat system. is BPI/database the best option. what u guys suggest

[thin panther]

I mean that's not much info really. Databases don't make much sense, and you'll need external tools.

BPI's don't do stat systems on their own. They're just interfaces.

[foggy saffron]

Can I get some debugging help? Why changing material does work but destroying the component does not?

Background is I'm using Meta's hand-controlled VR sample project, I want things to disappear when user touches collision box on themselves

I know what all dirty-minded people are thinking but seriously, this is just a hygiene training for a hospital 😂 😂 😂

[obtuse oriole]

how do I calculate angular torque needed to rotate an object to a target rotation? I tried few common method that involves converting the rotators to Quaternion and back to euler radian and apply it as Torque but all my attempts only lead to the object either spinning so fast in all directions or too slow as well not even going to the target

[gentle urchin]

Compoment is my preffered method for stats

[cyan spire]

https://imgur.com/a/S3tLtAV

[gentle urchin]

Since they contain logic and state already

[cyan spire]

Is there a wiser way to get the needed assets instead of using the "async load" node every time because it has just 1 input?

[gentle urchin]

You can wrap the loading in a macro

Taking an array of assets

Returning the asset + index when done

Or some c++ to expose a proper one

Macro one just automate loading the next entry

[gentle urchin]

also, you cant run off the top pin directly into using the asset. That's just to allow other stuff to happen while it loads. You need to use the asset after Completed has been executed

if you wanna go c++ route the call you're looking for resides in the UassetManager
UAssetManager::GetStreamableManager().RequestSyncLoad()

[distant grotto]

anyone know how to fix: LINK : fatal error LNK1181: cannot open input file 'delayimp.lib' when buidling? I did check and the file does exist, so I'm guessing unreal just cant find it

[warm parcel]

A widget interaction component returns isOverInteractableWidget regardless of InteractionDistance or if there is an object blocking LoS. Is there any way to return if the widget interaction component is over a widget that takes those things into account?

[dawn gazelle]

This doesn't really have much to do with blueprints and your best bet may be to ask in #cpp. A search on google indicates that you may not have everything required for actually building unreal projects.

[distant grotto]

Right I think I have to create a c++ project so unreal will install whatever is missing

[empty marten]

Can someone please guide me to a link that has a list of all nodes for Media Players and Media Playlists please in BP?

Each time I try and find a list it just takes me to generic documentation. I'm not after that. I just want a list of all nodes for Media Players and Media Playlists so I can see what each node does without having to open a BP and go through them 1 by 1.

[thin panther]

no such list exists

[empty marten]

https://tenor.com/view/why-just-why-but-why-monkey-gif-18202838286539704455

It would be so bloody useful for me right now if it did XD

[gentle urchin]

cant you just look em up in engine?

pretty long list lol

[empty marten]

There's no control F function though lol. I don't know all the nodes off the top of my head so use keywords when trying to find a node that does what I need hence a website lol

Yes I'm lazy.

[gentle urchin]

usually i just try searching based on typical namings, in the context of the media player

no way i remember them all. but i can find what i need 96% of the time regardless

[hidden rampart]

So I have a Diablo style inventory system with rows columns , items stored in an array, with drag an drop, all working fine( because its not mine it's from a tutorial) and I'm adding a simple stacking system to it, I've come a long way it works 90% now in most cases, but there's a really weird error/bug that i get and I have no idea what to do about it.

It works in every case except there are some slots that become unaccesable when dragging over them. They are a bit random but always in proximity to the stack that I dragged from. This issue only happens when I drag an item from a stack.

So the slots that are invalid or something, they don't highlight, and if I drop the item on them it dissappears. These ghost slots always appear in proximity around the stack where I dragged from. I can drop it in the rest of the slots and it works.
It's quite a weird issue, I'm not sure what to do. OnDrop isn't called at all when I drop on the bad slots. Drag is also not detected. Any ideas of where to look would be greatly appreciated!

[gentle urchin]

not very related but... stacking kinda goes against jigsaw premise, doesnt it ?

[hidden rampart]

what

[gentle urchin]

usually jigsaw is implemented to rather heavily restrict the players carrying capabilities

adding stacking kinda destroys that

oh well, was unrelated, ignore me 😛

[hidden rampart]

ok, i personally think it's a good feature, all my favourite games have it, diablo has stacking too

[gentle urchin]

only on very specific items tho, right?

single slots only ?

[hidden rampart]

yes and i plan to do that too?

[gentle urchin]

guess that changed in d3/d4

are you doing any visibility logic when you start a drag operation?

on the slot you drag from etc?

[hidden rampart]

This is when you drag

If anyone has any idea why would a few random slots in the vicinity of the stack that its dragged from become dead/ghost, OnDrag isn't called etc,, as seen in the gif above, let me know it would be greatly appreciated.

I dont even know where to look for the problem.

[gentle urchin]

it's very little to work from tho,

[hidden rampart]

And the dead slots change if you change the stack position

[gentle urchin]

the video only shows 1 item, it seem to be specifically 3 slots down in this case, but might vary ?

is there a connection between the size of the item and the dead slots ?

[hidden rampart]

that's an example of an item that's dragged from a stack, the dead slots are the ones where they dont highlight when the item go over them

[hidden rampart]

the dead slots are about the same number, they surround the stack

[gentle urchin]

and the "OnDragEntered" logic ?

[hidden rampart]

Nothing in that

[gentle urchin]

the logic that highlights the slots ?

[hidden rampart]

yes let me get it

[gentle urchin]

and the duplicate item object

function

[hidden rampart]

this isnt called though on the dead slots

this the Duplicate Function

[gentle urchin]

do the BP ItemObject do something with the Inventory ? Reserve space or something ? Or does it only exist outside of the inventory (for now) ?

[hidden rampart]

that is the item data blueprint, which holds the item information like stats size all that

The inventoryGridWidget spawns the itemwidgets

[gentle urchin]

That is known, but does it register itself to the Outer (Inventory) somehow? I'm guessing not, but thought i'd ask.

[hidden rampart]

There is the InventoryComponent which holds the array of itemObjects

[gentle urchin]

Right. Is that array altered during the creation of a new Item ?

[hidden rampart]

yea the Outer is the inventoryComponent

AddItemAt function adds it into the array

[gentle urchin]

I can't see that function being called during the duplication of the object tho

so it appears, to me atleast, to be free from the inventory, as of this moment

and not in the Inventorys Array

[hidden rampart]

yea I add it in OnDrop

is that not ok?

that might be the problem?

[gentle urchin]

That's fine

No, since we're not getting to OnDrop

heck, we're not even getting OnHovered

[hidden rampart]

yea we;re not

so weird

but just for a few slots surrounding the stack

eveywhere else it works and you can keep adding and making new stacks and readding

[gentle urchin]

The function that updates the grid... is that called when you start dragging a stacked item ?

[hidden rampart]

and for every stack, there are a few dead slots around them when you drag an item out of them

[gentle urchin]

you should add debug prints to most steps related to the widget, the slots, their creation, their updating etc

to see what gets called

[hidden rampart]

let me check

ok

[mild galleon]

Hello!
i have a question regarding "Filling an image in widget from a combo box selection (dropdown) via Data Table".
https://forums.unrealengine.com/t/filling-an-image-in-widget-from-a-combo-box-selection-dropdown-via-data-table/1984961
on runtime, my widget's image is not updated or even dissappears completely.
I have a combo box, and then select an entry from a data table. Said data table also has a link to a specific material instance in the same row.
(Edit: that material instance is supposed to fill my widget's image then automatically)
If anyone could point me towards the mistake, i would be super happy.
Thank you very much!

[hidden rampart]

I dont think it gets called

[gentle urchin]

half of the images dont work

hard to tell anything from them : P

[mild galleon]

ouch!

thank you for pointing that out, perhaps because i just uploaded them and it takes some time to update on server side?

here,

[gentle urchin]

hmm, works when i click it actually

[mild galleon]

ah nice 🙂

[gentle urchin]

wth

now they show natively aswell

[mild galleon]

was maybe just taking a minute from EU to US to update 🙂

[gentle urchin]

Im in EU 😄

is the material set to UI ?

[mild galleon]

probably not! thanks i check that out,

[mild galleon]

aha. and if i also want to use them in the game as well?

do i then need to have 2 base objects, materials?

[gentle urchin]

I believe so

[mild galleon]

wow.

thats an entierely different node, missing a lt

*lot

[wraith loom]

I accidentally closed an event graph, how do I get it back?

[mild galleon]

thanks a lot for the pointer, very appreciated

[gentle urchin]

open it from the side menu

above functions

[wraith loom]

ah thanks

[mild galleon]

great!

@gentle urchin you are amazing, thank you man

[gentle urchin]

I assume that was it then, and fixed it 😛

[steady night]

hey if im using a projectilemovement componenet with initial speed set to a fix amount how would i add speed to the projectle after spawnm ?

add velocity or ?

[gentle urchin]

depends on what you wanna do

do you want it to increase its speed?

[steady night]

yeah

[gentle urchin]

oh sorry,. i missed the how in your initial question lol

[steady night]

aye

[hidden rampart]

Hey does this look alright?

This is the OnDrop logic when you drop a stackable item on another item thats valid to stack

Does the payload need to be removed or the dragged item destroyed or something?

[gentle urchin]

this works, atleast

surprised there's nothing built in for this

this respects MaxSpeed

[steady night]

aye i notcied if i put it in construct it also worked

it added it

[haughty snow]

hey is there some non-spaghetti-node way to programmatically set the normal / hovered / pressed image + tint of a button? or should I just make a collapsed node that hides my multiple Brush Slate shame

[kind willow]

I think you have to do it one by one :\

I suggest making a master button and reuse it so you only have to set it all up once

[lilac hill]

Why am i having such a hard time to accomplish 6DOF?
No matter what pitch and yaw somehow make the character roll when i'm using "add actor local rotation".
Is it something obvious i'm missing?

[ashen jungle]

Hello
I was trying to read a variable from a blueprint and set a text in another blueprint with the value of the variable but its giving a error like "Acessed None trying to read[...]"
I'm new to Unreal so i wondering if someone could help saying what is wrong

[steady night]

shouldent this spawn them with a rotation like a 45 degrees ?

[haughty snow]

ah damn ok thanks

[lilac hill]

If it's index 0 you're multiplying 45 with 0, which is 0

[steady night]

for the first one yeah but 1,2 should be 45,90 right

[lilac hill]

Depends what the Roll value is. But why are you subtracting 90 first?

[steady night]

im doing a "multishoot" wanan fire 3 arrows in a line

or arc rrather

[lilac hill]

and you're sure they don't spawn with a roll? tried printing out the roll values when they're spawned? and tried printing out the roll value here before spawn?

[steady night]

ive tried them all but should be roll yeah,

[spark steppe]

that's super speculative

considering that you get whatevers rotation in world space

[lilac hill]

what does the printouts say? take a screenshot

[steady night]

prints work

[spark steppe]

RTS World space is most likely wrong (unless you compose it like described below)

to build your initial rotation

you most likely want to build the spawn Transform first, and then compose it with the socket transform

[steady night]

change it after spawn ?

[spark steppe]

also roll would mean that the arrow actors forward vector is Y?!

[lilac hill]

i assume he want's the arrows to spin?

[steady night]

nah i want them to be spawned in a arc

pitch* it should be

but its not changing

[spark steppe]

did you do what i suggested?

[steady night]

hm

build spawn transform first and the compose

[lilac hill]

well you're setting the rolls on the object, you're not spawning them in an arc.
the thing shooting them needs to move in an ard, or you need to get a direction that moves in an arc

unless im off

[spark steppe]

yes, or make a rotator and compose it with the rotator that you get from your socket

[steady night]

hmm

wdym?

like so ?

[spark steppe]

no

that's the same in green

search compose transform

or compose rotator

either works

[steady night]

hm okey

[spark steppe]

combine rotators, sorry

[steady night]

?

[spark steppe]

why do you split all pins...

first one is only the pitch that you calculate

2nd is the one you get from the socket

[steady night]

:/ ?

[spark steppe]

first one IS ONLY pitch that you calculate

[steady night]

oh

[spark steppe]

just index * whatever result

nothing from the other

[steady night]

oh okey well yeah ive done that but theyre all spawning the same

the print value is different for each

[spark steppe]

NOTHING

FROM

THE

OTHER

[steady night]

xD

ok

[spark steppe]

if they still all spawn the same try the pitch input as roll input (maybe your actor has the wrong forward vector 🤷 )

[steady night]

nah i dont get it im dumb

[spark steppe]

yea i got that by now

show a screenshot

[steady night]

[spark steppe]

of what your current setup is

[steady night]

oh

so the brewake rotator is not needed either

[spark steppe]

yea

[steady night]

https://gyazo.com/4233225644dda26a8501536dde20a0ca

the values are diffrent from eachotehr but theyre all the samew

[gentle urchin]

Gimbal?

[spark steppe]

i've watched it 5 times now and i'm not sure what i'm supposed to see here?!

[gentle urchin]

Print string upper left

[spark steppe]

did you try roll instead of pitch?

[steady night]

yeah

[gentle urchin]

Z stuck at -180

[steady night]

which ever i change they all spawn in eachother

[gentle urchin]

You wanna combine them the other way around I believe ?

[steady night]

omg

i

think

i found

it

so dumb...

[gentle urchin]

It often is

[spark steppe]

that's a world rotation at this point, so it could also mean that the actor is just facing that direction

[steady night]

sigh...

[quaint fable]

Hey! I have a video/cut scene (mp4) that I want to play when the player overlaps a trigger. How can I do that?

[spark steppe]

trigger volume...

[steady night]

the propjectiles were overlapping eachother and being destroyed at spawn... so only 1 left

[gentle urchin]

Lol

[steady night]

so my first settup worked also

lEl

[gentle urchin]

Awesome - solved, next

[steady night]

https://tenor.com/view/iceage-possum-peaceout-gif-2272177960667492692

[spark steppe]

never ever worked your first setup

[steady night]

you dont think ?

[gentle urchin]

Not an untrue statement

[spark steppe]

i'm 99.99999% sure

your old setup was manipulating one fixed axis which was a world axis

the moment you look up/down the axis you want to rotate around will change

while your old setup would still blindly change the fixed axis

but you'll figure this out later, because this wont be the last time that you encounter such math problem 😄

good luck next time xD

[steady night]

= )

probably

thanks either way

[dapper wave]

Hi, sorry for asking here but I really didn't know where to.

I was wondering if you can make an animation sequence (that is falling forward for example) to somehow sense if it is a wall in front and not go through it?

[vital cargo]

I have a question, I've created a save game for my game, it saves the variables correct but when I open the game back up and load the save game, it has to spawn the actors in but if it has to spawn more than 2 actors it just spawns them on top of each other. Anyone know why they seem to all be getting the same Transform from the save instead of taking the next one in the sequence? It's all saved within a Map and an Array

[haughty snow]

its absolutely disgusting but this worked lol

[visual ember]

hard to tell without seeing the code. have you looked into the map whether it's being saved and read correctly? is "the same transform" perhaps basically (0, 0, 0)? or maybe that of the first or last actor?

[vital cargo]

Sorry, I was grabbing a SS of the "load game" BP @visual ember

So, if it saves 2 actors, it will spawn them in the correct spot where they were previously saved BUT the second I add a third actor, they all get set with the same Transform as one of the 3 that had been saved.

[vital cargo]

Yea, I ran a print string at each stage just to make sure the correct transform was being saved, they were it's just when loading back in they seem to all get give one transform if saved actors > 2

This is saving on the game instance and the second one is updating the struct on the actor itself

[visual ember]

have you tried passing transform directly to the spawn node?

[vital cargo]

I literally didn't try that until now but it's the same issue.

[visual ember]

and inspecting the Plants map all seems fine?

and when/where is it that you are calling the spawn node?

[vital cargo]

Yup, all 3 are different when saving

[vital cargo]

Game instance, once the level opens up (with a .2 delay) it runs a check to see if a Save Game exists and load the items if they do exist.

[visual ember]

hit it with 2s delay quickly 😛

(and don't rely on delays in the future)

[vital cargo]

Actually the level blueprint didn't have a delay, I thought it did. I tried with a delay and it still spawns them ontop of each other

This is the Level Blueprint

[visual ember]

breakpoint in the plant's GameLoad, right on the set transfrom node and see if details are fine from there

[vital cargo]

I know how Breakpoints work within Visual Studio but how do they work within the BP editor?

[visual ember]

or even at the Set node before

select node, hit F9, play

sometimes need to select object instance at the top, but most of the time it just works and finds one for ya

[vital cargo]

I got it working. It only gets called once even though it spawns 3 of them

Ignore that

Ok, I advanced single frame, they all have the same Transform

[visual ember]

this relationship is sus

[vital cargo]

so the Plants Map is reading the Map that is on the save game and the Plants Actor is to just loop through each Plant and get the correct details of each one (Growth timer, health, water level etc etc)

Can we actually use maps & structs within saves or does that become messy? Also it's 5.4

[visual ember]

oh wait a second. are you saving object reference in a game save file?

[raven gyro]

is there an alternative for sequence? xD this thing is firing like crazy

[vital cargo]

So I save the Actor to an Array and then save the Actor + Struct to a Map.

[visual ember]

don't save references

[vital cargo]

What would be the correct way to save it then?

[visual ember]

objects on next run are totally different things and inter-object references are going to be different

you already have a struct of plant data

save that

recreate plant from the data

on load

[vital cargo]

Is there a way to get the length of the Map? So I can spawn the exact amount.

[visual ember]

why not just iterate?

but you can get keys or values as arrays and get length from them

[vital cargo]

Ok, I can get the Keys and then use them to match up and spawn.

I was trying to iterate but is there another method to get something from a map other than Find?

[visual ember]

but at that point you don't need map anyway. initially though a good place to start

[visual ember]

array of Values and then iterate that

[vital cargo]

I'm very new to Save Game and handling the data, this is my very first time doing it. I was following a tutorial and tried to adjust it for my items.

[visual ember]

you'll get there soon and change your name to TheWheelieGoodGamedev

[narrow pendant]

is there a way to adjust the size of a NavMeshBoundsVolume at runtime?

looking to set these values

[vital cargo]

When I figure this out hahaha.

Since I have stopped playing games for a while

So something like this?

[visual ember]

no need to get keys to then find within map. just get values and iterate on that

[vital cargo]

Ohh, ok

omg

That worked

Now sound like a crazy person next to my friend laughing out loud

I was overcomplicating it so hard.

Then I don't even need to save it as a map, I can do it as an array

[visual ember]

proper design? you sure all of that has to happen on a single click? you sure this one single thing has to do 25 different things?

[raven gyro]

one button affects 25 things, but only if boolean is true

for that index of 25 things

[visual ember]

you can change it to an event/command, to which all other objects will subscribe

[raven gyro]

someone told me try switch on int?

[narrow pendant]

there is way too little context to help you with anything there nguyen 😄 this looks very cursed though

[visual ember]

I have no idea what is going on after the sequence. from current info I can tell you are calling way too many things

but you might as well have all of them ending on a reroute node and doing nothing 😛

[raven gyro]

it trigger something like this

but boolean index must be exact for it to trigger that macro

[visual ember]

just for loop it lol

[narrow pendant]

so you're calling the same thing and increment that value by 1?

yeah just for loop it 😄

[visual ember]

morphs do differ, but that one can be in an array too probably

[spark steppe]

foreach on an object array

[visual ember]

or that, and get index

[raven gyro]

okay ill try xD noob coding 😄

[narrow pendant]

do you get the basic idea of foreach / for loops?

[raven gyro]

yeah pretty basic, but still get confused here and there 😄

[vital cargo]

Thanks for the help @visual ember Just changed things and removed the Maps and changed back them back to Arrays. I just overthought it hard.

[visual ember]

I interviewed a 5+ years of experience dev once. he failed to use a for loop in his solution and just wrote things similarly to this :V

[narrow pendant]

yeah no shade nguyen this confused me greatly when I first started 😄

that is concerning though mars 😄

[raven gyro]

its my 1 month experience 😄

[visual ember]

I still sometimes connect return from a function on the Loop Body flow instead of Completed

[narrow pendant]

guilty

[raven gyro]

i made this for setting specific boolean i want so not bad start

thanks for help yall

[spark steppe]

you can put the 2nd set array element node on the completed pin

and return from there

instead of setting it each iteration

[vital cargo]

@visual ember I lied

[visual ember]

https://tenor.com/view/kounotori-kto-stork-dafuq-gif-24170861

[vital cargo]

Now it occasionally duplicates an actor. Not sure if it's the last one in the array or a random one, just doing a little debug and testing it haha

Let's just say, it's gone from 9kb, to that number haha

wait wait wait. That's a me fault.

I'm not clearing the array before adding the new data to it again, it's just duplicating it

It works, just the array not being cleared was the issue, thanks again

[visual ember]

https://tenor.com/view/atg-capa-stucapa-studiocapa-pandu-gif-24944547

[vital cargo]

I spent the entire day yesterday trying to figure it out, I don't like save games anymore

[spark steppe]

that says goat

it's just a really weird font

[vital cargo]

I'm going to keep a sticky note around saying Mars is a god tier helper haha

[visual ember]

watch it becoming a cult, people worshiping some god named Mars or sth

[narrow pendant]

https://www.youtube.com/watch?v=cXOanvv4plU watch wheelie make this his alarm sound and step to his altar to make a blood sacrifice first thing in the morning

[cedar sparrow]

Why do GameModes have a viewport?

[narrow pendant]

it's just an actor apparently

[vital cargo]

@narrow pendant Just need to find an alter now @visual ember

[visual ember]

https://www.ostia-antica.org/regio2/7/7-3.htm

[narrow pendant]

this is getting concerning

[vital cargo]

shushes quackcharg3 it's ok. You don't need to be concerned, unless you're my neighbor 😉 😂 I kid

[distant grotto]

remove from viewport seems to only remove the visiblity of the widget but its still blocking clicks and not getting deleted. Is there a node that properly deletes widgets?

[empty marten]

Try either Get All Widgets of Class and then out from that Remove from Parent.
If that doesn't work you can also try DestroyComponent.

[distant grotto]

destroy component seems to only work with actors, get all widgets didnt help either, getting the same behavior

every time I click it fires the event

the widget becomes invisible but its still consuming mouse inputs

[loud tree]

"Set input to game" click the node that comes up for game only.
If that doesn't do it.
My guess would be you need to designate it to happen locally per player, or your input is disabled in another manner.

[distant grotto]

I'm using game and UI input because its a top down click to move setup

collecting garbage actually gets rid of the widget, but my input is still messed up so I'll try resetting the input mode, even though it shouldnt have changed

[loud tree]

What BP is that SS from?

[distant grotto]

SS?

screenshot?

its from the widget event graph

its just an info popup that is meant to dissapear with any mouse click

[loud tree]

Yes

In the first one it had a get all widgets of class so I was checking

[distant grotto]

I figured it out, it was this

on the click events

[empty marten]

Hey peeps,
Anyone know why this Open Source with a media player target is struggling to open a media source even though the directory is correct? The only error in output log I get is this.

[distant grotto]

dumb m mistake

[loud tree]

I do that at least 10x a day minimum.

[eternal gate]

Is there any way to view parameter values that were set in a blueprint's UASSET file? I have an asset from an old project that I want to see the values from, but I don't want to reinstall the older version of UE just to open the project and look at the blueprint

[fierce oyster]

try using a File Media Source asset to reference the file

[empty marten]

Literally doing that the node before it lol

[fierce oyster]

I mean by using the actual asset so you can use the "Choose a file from this computer" option that can report possible issues

[empty marten]

How do I do that sorry? I don't use media players often so I'm not familiar with all of its nodes.

[fierce oyster]

on content browser

[empty marten]

Oh I have that.

[fierce oyster]

check what it says on that icon

[empty marten]

It say the files are outside the Contents\Movies\ folder

Does that mean I have to make that folder and just have the videos in there or do I have to make that folder in my content browser?

[noble ledge]

Is there any easy way to append to a structs array?

[fierce oyster]

you can create the folders the way you prefer as long it's the same path

[empty marten]

So why does it keep changing the file path in the file media source to a directory in the engine binaries?

All I'm trying to do is get the files from a single directory, get 1 of those files, set the media and then have a media player play the video.

[fierce oyster]

you need to set the path for your .mp4 files that should be located inside Contents/Movies

just click the 3 dots at the File Path

[empty marten]

OK Sorted.

So is that folder happy to have folders in it or does every video have to be in that 1 folder?

[fierce oyster]

can have many folders

[empty marten]

Cool. I should be able to do what I need to now. Thank you kindly for your help 🙂

[maiden wadi]

@empty marten The reason for this is that most media files are not directly hard reffed. Media stuff is done via path in almost all cases and the engine is specifically coded to pick up and cook content in the Movies folder so that you don't end up with an uncoocked/unpacked movie.

[river hill]

hey i didn't know where to ask this, but i would like to ask if anyone has a simple solution to respawning a player to a location when falling out of bounds, i followed the only tutorial i could find and when completed it was not up to the standard i wanted as it did not work, does any have any easy solutions that i can copy from a screen shot? many thanks - splatty

[hallow wyvern]

I need to cut a skeletal mesh. create seamless various seams (not cut plane) dividing the skeletal mesh into 5 parts (i.e. without filling, not boolean). Runtime

I see options

Mesh Ops - Mesh Operations Plugin
Solid Geometry Lib Plugin

I haven't been answered yet whether it is possible to solve the problem with these tools, but if not, what method could you advise me to do? It seems like an impossible task for UE? (at the moment).

Thank you..

regard, kisses

[warped juniper]

I have a small issue regarding movement switching movement modes with the Character Component
The actor is supposed to go from Flying to Walking (then falling if not touching ground by then) and do so with NO velocity.
I made sure to reset it before making the switch, but the actor seems to remember the last update velocity and continue the trajectory, even with no input, when making the movement mode switch.
Is there a way to ensure the lateral velocity is truly reset after this switch?

[bold wedge]

I have a Spline, and its made up of a number of Spline Meshes with a texture on each. What I'd like to do is have this texture (5 strips) cover the full length of the Spline (not repeat over each segment). I've been trying to do this for hours with no luck so far. Anyone have any ideas?

[gentle urchin]

show code

[bold wedge]

for genarating the spline?

[gentle urchin]

Yeah

[bold wedge]

The things I've tried is setting the UV based on the spline length / the segment size; didn't work.. I've done the WorldCoords, Local Position, Object Position in the material, but thats not really doing what i want. I think I need to get the UV for each Spline Mesh, but I don't know the magic math for each UV.

[gentle urchin]

Ohh right, my mistake. Re-read your question, and it's clear that its a texturing issue, nothing else 😛

not enough coffee

[bold wedge]

Yeah, the Spline is looking ok

I just can't get his UV stuff sorted

[gentle urchin]

I doubt you'd get away with anything less than material instances, with UV inputs

this is more of a #materials question tho, that's where the masters are hiding

[bold wedge]

I have dynamic materials instances on each Spline Mesh

oh, ok... I'll try there

[gentle urchin]

good start. I'd imagine you'd need to set parameters per instance, based on its relative length, and position

so that you offset the textures

and stretch as necessary

[bold wedge]

Thats what i've been trying to do, but my math regarding getting the UV's correct are fail

Its a mix of blueprint and material fun

[viscid fossil]

Hey people, I'm not too sure where to put this so hopefull this is correct. I want to make it so when I click E on a certain collision box (sacrifice altar) while holding another collision box (Dead deer), it makes the collision box (dead deer) disappear. Any Ideas? I have already set up my grab system. Happy to jump in a call is someone knows how to help :))
heres a video if it helps any

[pseudo fulcrum]

Two functions, one is a called custom event for completion of a file download.

I'm able to recover the results of the second function which is the custom event (Function B) if I call function B di rectly, but how, on function A, can I obtain the results of function B?

Function B has a return node, but I'm needing the created event of function B on function A to pass the result of the function B back to the created event A, and then through to the return node on A.

[gentle urchin]

you cant create an event inside a function

if the function matches the callback, it can be seleted in the dropdown list

If im unsure about the callback params i usually just create the event with the delegate, then convert to function afterwards (if that's what i want)

[sand bloom]

So ever since learning structs are bugged in blueprints I am looking at ways to do a simple inventory setup in other ways, i'm prototyping a 3d inventory system like resident evil 4 or the forest etc. It needs to spawn the inventory items in, but i'm wondering how do you save the unique variables inside a actor without a structure? Like the amount of a item would vary per item, because when spawning in from an array you're using a class but a class is generic. It wouldn't hold the saved variables

What would be a good way to save variables 🤔

Normally I would use a struct inside the actor and just save the struct but like yeah that's not really an option in blueprints so i'm seeing what alternatives solutions people know of you know?

Normally a structure kinda would act as a container for variables to save, i'm looking at other containers for variables I can save

[frosty heron]

wdym by it;s not an option in blueprint?

[sand bloom]

Structs are notoriously bugged for blueprints and will give you issues generally

[frosty heron]

I wouldn;t say structs are bugged in blueprints. Structs declared in blueprint is bugged

[sand bloom]

So I need like an alternative for storing variables

[frosty heron]

yeah just declare them in cpp and you should be fine

Creating the struct in cpp is not hard

[untold fossil]

How can I get this variable type without it being embedded in a slate brush? I don't want the extra slate brush struct stuff, I just want the image variable type which can take both textures and materials. How do I get this?

[sand bloom]

That was a terrible experience that refused to work lol i'm not trying c++ again

[frosty heron]

well if you limit your self...

[sand bloom]

I get what you mean but I tried 2 times and with different scripts

neither worked

[frosty heron]

I don't know what script you are talking about

[sand bloom]

I am literally limiting myself yes, there should be a way to do this I imagine

[frosty heron]

yea just make them in cpp

[sand bloom]

oh someone here shared one and I also found one on the unreal forum

[frosty heron]

and save your self the trouble

You are looking for a way out

there isn't a replacement for structs

everyone usses it

[sand bloom]

It doesn't need to be 1:1 just like fullfill a similar purpose even if it's not as efficient

[frosty heron]

just bite the bullet...

or stick with broken blueprint struct

[sand bloom]

I did two times and it didn't work

[marble tusk]

Then you could just use multiple arrays of individual variables, no?

[maiden wadi]

You either learn C++. Or you learn to get good at replacing pins when they break. 🤷‍♂️

[frosty heron]

you know you can just show the code right?

[sand bloom]

Ah that's not a bad idea actually, that might work thank you i'll keep this in mind lol

[frosty heron]

and maybe someone can pick up what you did wrong

[sand bloom]

I don't think the code was the issue because it wasn't my code

but maybe I pasted it wrong

which is very possible

[frosty heron]

I don't see how that replace structs

[sand bloom]

I could try and save stuff trough that as a clunky method

but yeah maybe it wouldn't pan out

[frosty heron]

you can just bite the bullet and ask for help if you are stuck

don't really need to learn c++ to create structs

if you are using unreal engine 5, you can see the header of your blueprint struct

you can copy paste that to your source file

[sand bloom]

This was my latest attempt, I made a new c++ class, I wasn't editing unreal itself. I figured a issue was it not referencing the right files so I left in that top section but that didn't work either lol

Unless this script is literally made for editing unreal engine's struct class whatever thing

To be honest I don't see how this code could give me a struct to begin with so maybe that's the issue

[frosty heron]

@sand bloom make a dummy blueprint struct

then right click and select preview header

you don't need .cpp file , just dump them in your .h file

[sand bloom]

you mean like this?

[frosty heron]

Also change GENERATED_USTRUCT_BODY() to GENERATED_BODY()

[sand bloom]

So is the idea that I make a struct with variables, do this header preview and then put that inside the c++ class's .h file?

Or is this for something new altogether

[frosty heron]

in your dummy blueprint struct, just add what ever variable or properties the struct should contain

when you are done, create a CPP class, but delete the .cpp
In the header, copy from the dummy blueprint struct header and paste in the .h file

[sand bloom]

Hmm alright i'll try that but if I did that where would the result of the .h file show up in unreal engine?

Would it be a new thing that functions like a structure basically?

[frosty heron]

it will come out as a regular struct in any blueprint class

[sand bloom]

Right on

[frosty heron]

USTRUCT(BlueprintType)

[sand bloom]

I'll try that right now

[maiden wadi]

Remember to close the editor entirely when compiling.

[sand bloom]

So when you say paste that into the .h file.. do you mean overwrite anything in there, or paste in a specific spot making sure to leave something existing

[sand bloom]

oh right that sounds familiar

I'll save the old code/text just incase and just overwrite everything

[frosty heron]

not a programmer, so I don't know what Im doing most of the time but maybe you need the .generated file and core minimal

[sand bloom]

Ahh okay

[frosty heron]

just show the .h file when you are ready

close editor then try to compile

Paste any build error if there is any

[sand bloom]

this what i tried to build, 22 succeeded but 1 failed and 1 skipped

[frosty heron]

you should have #include "thefilename.generated.h"

below core minimal

Also show the build log

[sand bloom]

I added that and rebuilt it

uh

[frosty heron]

can you show me the whole screen shoot of your visual studio

you don't want the error tab, you can close that forever

need to select the build tab

[sand bloom]

so when you said you don't need the c++ file you probably meant ignore it, don't delete it lmao i'm sorry

[frosty heron]

you don't need the .cpp one

can delete that

[sand bloom]

oh okay

[frosty heron]

don't write thefilename literary lol

[sand bloom]

it's a bit of a mess

[sand bloom]

lmao dang

[frosty heron]

#include "StructTesting.generated.h"

[gentle urchin]

^

[frosty heron]

click on the output and paste the log from there

[sand bloom]

imaybestupid.jpg

[gentle urchin]

ErrorsWasMade.Org

[sand bloom]

alright i'm in output after doing another build

[frosty heron]

2>G:\unreal\SurvivalHorrorProject\SurvivalHorrorProject\SurvivalHorror\Source\SurvivalHorror\Public\StructTesting.h(16): error : Found 'Item' when expecting end of type declaration

you can't have space buddy

replace them with underscore

e.g. item_class
or ItemClass

[sand bloom]

ohh yeah i copied an old struct I had for inventory stuff

I'll have to keep that in mind

[frosty heron]

build again and god speed

after fixing line 16

[frosty heron]

it's not a mess btw, it's just intelli sense is broken. There is kinda a pay wall imo to make coding bareable for unreal

[sand bloom]

yeah i heard rider is the way to go or something

[gentle urchin]

Rider for life

[frosty heron]

@sand bloom ok I was gonna mention this before

so like, your enum have to be declared in cpp too

[sand bloom]

it's strange how it mentions not finding a enum

oh

[gentle urchin]

EMyEnum

UENUM(BlueprintType)
enum class ESqsQuestState : uint8
{
    /* Not available for any reason */
    NotAvailable    UMETA(DisplayName = "Not Available"),
    /* Criteria is not met*/
    Pending            UMETA(DisplayName = "Pending"),
    /* Criteria met but quest not accepted */
    Unlocked        UMETA(DisplayName = "Unlocked"),
    /* Quest accepted*/
    InProgress        UMETA(DisplayName = "In Progress"),
    /* Quest Completed, ready to reap the rewards*/
    Completed        UMETA(DisplayName = "Completed"),
    /* Quest reward  granted */
    Done            UMETA(DisplayNAme = "Done"),
    /* Cancelled for whatever reason*/
    Cancelled        UMETA(DisplayName = "Cancelled") ,
    /* The quest is failed, and thus unavailable */
    Failed            UMETA(DisplayName = "Failed")
};

[sand bloom]

So instead of making my enums inside blueprint I need to like do a similar thing to the struct?

[frosty heron]

you can't really reach blueprint declared stuff in cpp land, that's why the normal workflow is to declare things in cpp

[frosty heron]

you can do it inside the same header file. Show me your enum. maybe we can help writing it (Squize already gave example above)

btw I pray you have version control system

[surreal bridge]

I am running into an issue where the variable passed into a widget when created is different than the variable inside of the widget.

I used various print methods and the class variable I am using to create the widget is valid and has the correct data. However, the actual widget's variable is non existent.

In the second image, the Item variable is not set

[gray ingot]

Hi, i don't understand why it is giving me this issue, i haven't set any variable to read only.

[sand bloom]

So I guess I should just try to make a new c++ class again and use what squize posted as a template? Although I don't know where, would this be in the .h again instead of the cpp/c++?

[gentle urchin]

.h

i'd probably just have it in the same file as the struct using it

[sand bloom]

oh right I guess that's a thing you can do huh

[gentle urchin]

all in the same file here. They belong together since they're used together. I dont expect anything else to use this

[sand bloom]

so as a quick example.. would I just post it underneath?

[gentle urchin]

above

it's read from top to bottom

so it needs to know about the enum before it tries to use the enum

[sand bloom]

Oh I see, and would doing a enum this way mean I can still read it in other ways normally in blueprint too? I imagine it would right

[gentle urchin]

yeah

[sand bloom]

that's good

hmm does this look right? I'm kinda worried it pasted inside the include stuff

[gentle urchin]

looks alright

so you'd now change the enum below to use ESqsQuestState

I'm doing it like this;

UPROPERTY(BlueprintReadOnly, Category = "QuestData")
    ESqsQuestState QuestState = ESqsQuestState::Pending;

[frosty heron]

Copyright™ strike 💢

[gentle urchin]

I got no copyright at the top 😦

[frosty heron]

// * Do what ever f*** you want

[sand bloom]

im not sure what this means

[gentle urchin]

this is how i declare the enum inside the struct

[sand bloom]

Oh

[gentle urchin]

instead of TEnumAsByte

[sand bloom]

Do I have to put something inside the struct or enum to make the struct notice it/declare it

[frosty heron]

for the struct to use the enum, it has to be declared before being used

so on the top for the enum

[sand bloom]

uh okay so literally on top?

[frosty heron]

This is what mine looked like

[gentle urchin]

Not the last snippet (UPROPRTY)

that's to replace your struct variable for Item

replace with

    ESqsQuestState QuestState = ESqsQuestState::Pending;```

[frosty heron]

show the enum for your item?

the blueprint version

[sand bloom]

Yeah I was going to edit it to fit my enum but I am still confused as how to make it work with the stuff on top 😅

[gentle urchin]

All you need to do now is use its type in your struct

[frosty heron]

the struct knows what to use because the enum is declared above

[gentle urchin]

So you have
EMyEnum Declared before FMyStruct, and can thus use it inside FMyStruct

the declaration you have is the thing you need to do to use it inside the struct

[sand bloom]

Right that makes sense, I think

oh

[gentle urchin]

if it were from another file you would include that .h file, which ecuates to the same as having the declaration before the usage

There's also forward declarations but thats for another summer

[sand bloom]

So I need to do this part in my struct? I don't understand this snippet I think

Like the enum part makes sense

[gentle urchin]

That snippet is a variable

[sand bloom]

but this snippet i don't really get it I think

[frosty heron]

declare your enum here

[gentle urchin]

UPROPERTY exposes it to the reflection system, BlueprintReadOnly makes it Blueprint Readable

[surreal bridge]

I am getting this error quite a bit:
Attempted to access a missing property on a CDO

[sand bloom]

so after the enum and before the struct

[frosty heron]

UENUM(BlueprintType)
enum class EItemType : uint8
{
    Consumable    UMETA(DisplayName = "Consumable"),
    Equipment    UMETA(DisplayName = "Equipment"),
    KeyItem        UMETA(DisplayName = "KeyItem"),
    LoreItem    UMETA(DisplayName = "LoreItem"),
};

[sand bloom]

Ah yeah that sounds important

[sand bloom]

ah thank you yeah that seems to fit the blueprint equivalent perfectly

[sand bloom]

so now I change the snippet between enum and structure to fit my enum

instead of questdata

and literally just name it itemtype instead i guess

[frosty heron]

Yeah, the quest data is an example, you are suppose to change it to what you need

it's just naming yes

[sand bloom]

so queststate becomes itemtypestate too?

I'm guessing I just rename all of these

[frosty heron]

@sand bloom What's the default value for the ItemType? Or w/e you want to call that enum

btw add the E as a prefix sorry, don't write ItemType . Do EItemType for enumeration

copy paste what I have first above the struct then show what you have

[sand bloom]

what I dont understand is why it is called quest state and not questdata state

oh okay

the default was just consumable

[frosty heron]

I updated the code, copy paste it again

lore item missing display name and enum class ItemType should be enum class EItemType

[sand bloom]

oh right

i see

I updated it

[gentle urchin]

FItemType*

[frosty heron]

oof

[gentle urchin]

Always

F Prefix

for structs

[frosty heron]

F for struct?

E for enum?

[gentle urchin]

yes

oh shit

yes

😄

[sand bloom]

hm

I see

lol

[gentle urchin]

E ^!

EItemType

[sand bloom]

so in this case e works

[frosty heron]

capital

[sand bloom]

oh yeah

[gentle urchin]

and remove this

[gentle urchin]

removeee

[sand bloom]

I thought I needed that to declare it for my structure to notice it

[frosty heron]

UPROPERTY(BlueprintReadWrite, EditAnywhere, meta=(DisplayName = "ItemType"))
EItemType ItemType = EItemType::Consumable;

[gentle urchin]

It is now named EItemType

[gentle urchin]

and it must be inside the struct, if you want the struct to use it

[sand bloom]

oh

[gentle urchin]

it already knows to use it because of the above declaration

[frosty heron]

make sure you use BlueprintReadWrite specifier if you want to set the value in blueprint

if you see BlueprintReadOnly, you can read but you can't set/write

[sand bloom]

Ohh yeah that's a good reminder

[frosty heron]

show updated version?

[sand bloom]

Definitely generally want to do that I think

So uh, I put the new snippet inside my struct?

this is what I had

[frosty heron]

yea that needs to go inside

[sand bloom]

so i put that middle one insdie

okay

[frosty heron]

yes, that's your member variables of your struct

[sand bloom]

inside generated body?

[gentle urchin]

after public*

[frosty heron]

place it in the order you like

[sand bloom]

so something like this you mean

[gentle urchin]

the scope of the struct starts at the {and ends with the }

[frosty heron]

looks allright, try building

[gentle urchin]

anything outside those brackets are not in the struct

[sand bloom]

Right

[frosty heron]

you will have to replace your blueprint enum to the cpp one btw if the build is succesfull

[frosty heron]

but lets leave that for later

[sand bloom]

oh yeah i'll overhaul stuff in general in the future

[gentle urchin]

ItemType should probably be EItemType ?

[sand bloom]

and i'll need to write down notes for future reference on this to ensure I remember

[gentle urchin]

same for consumable, but i guess you havn't decleared that one

show the entire struct now

[sand bloom]

oh this is my struct

[gentle urchin]

remove line 47-48

and 59-60

[sand bloom]

oh okay

[gentle urchin]

Success ?

[sand bloom]

So I'm guessing the issue was it was calling something that didn't "exist"

[gentle urchin]

yes, the last lines, 59-60

was not declared in your file

the "ConsumableType"

[sand bloom]

that makes sense

[gentle urchin]

The process is the same for that one, duplicate EItemType,

[sand bloom]

yeee

I'll work on that one too with the same methods

and see if that works

booting up unreal rn

[frosty heron]

delete your dummy blueprint struct

[sand bloom]

oh I think I already did

I deleted a empty one just now

But how would I now access this in unreal 🤔

[frosty heron]

create a variable and assign your first C++ struct

just like how you make your blueprint struct in a blueprint class

[sand bloom]

That's the thing, I still don't see it I think. Like Structtesting is what it should show up as right?

[frosty heron]

InventoryItemStruct

[sand bloom]

oh

right

lol

[frosty heron]

the F should be excluded

[sand bloom]

wait but I already have one of those, won't these conflict

I should probably rename it

[frosty heron]

yeah it will conflict, you will have to replace the blueprint version

then delete it

[sand bloom]

Can I just rename the blueprint version first before i delete it?

[frosty heron]

you can

rename the blueprint one, so u know where they are used

replace them one by one then delete the bp one when you are done

[sand bloom]

uh I still don't see it

maybe i need to reboot the editor

i'll just build again one time and reboot

I did reboot already but

[gentle urchin]

you should boot from VS

[sand bloom]

oh really

[gentle urchin]

yeah

[frosty heron]

you might not build for the right target

development editor if u are starting from uproject from my memory but honestly I just boot from IDE anyway soo 🤷‍♂️

[sand bloom]

hm

[frosty heron]

screen shoot your VS

[sand bloom]

I pressed play but that's a debugger haha

oh huh is this needed btw

[frosty heron]

no

dont add semi column there

[sand bloom]

oh okay

i gotta see how i launch unreal from this

[frosty heron]

I dont really use Visual studio but can you check if

Development Editor and see if you can see your project name instead of UE5

[sand bloom]

yeah that's what I tried and said this

oh yeah

ill check for my project name

wait it doesnt show up

is launching from a ide required?

Does c++ not show up in unreal otherwise 🤔

[frosty heron]

no but recommended

[gentle urchin]

you'd need to ensure that the editor launched from the Epic Launcher is the same as the one you're building towards

[sand bloom]

that's fair, I don't think it's recognizing it right now however

[gentle urchin]

But easier to just launch from your IDE

[frosty heron]

for debug you will need to set the build to Debug/Debug game

if you gonna open uproject, make sure DevelopmentEditor when building

[outer forge]

Is there a way to do something like BoxOverlapActors but based on a collision object (which isnt always active), so that I can visually tweak its transform?

[sand bloom]

this is what I have

[frosty heron]

DevelopmentEditor

[sand bloom]

it still gives a debug error

[frosty heron]

dont debug

just build first

I don't know the shortcut to play in VS

[sand bloom]

oh right

[gentle urchin]

you can query it for its current colliders, once you activate it
And otherwise use its delegates

[sand bloom]

i just built

[frosty heron]

maybe F5? or f7? guessing at this point

[sand bloom]

so i built and press the play button

[frosty heron]

yes

[sand bloom]

and same error

[frosty heron]

what error

[sand bloom]

even when trying this

[frosty heron]

I am not fammiliar with Visual studio, if no one else can help . Just open from uproject for now

can ask in #cpp for more support in regards to that

[outer forge]

Thanks! But do I have to activate -> query -> deactivate? The idea is to only query for a single frame, when I need it, without wasting performance on the average frame

[gentle urchin]

If im not mistaken, these already work async, but yeah if that's the case , sure

you can also do box trace, drawing a debug box while in editor, for example

[sand bloom]

🙏 I appreciate the support you both have given me so far, super helpful. I don't mind using uproject

I just need to like have c++ stuff show up inside the editor lol

maybe this new build will have done it

[frosty heron]

check if it show up now

[sand bloom]

because it specifically targeted the right thing

it's booting rn

maybe it being slower rn is a good sign idk lol

[outer forge]

That also sounds neat, gonna try it out. Thank you!

[gentle urchin]

dirty example

[sand bloom]

hmm okay it's still stuck on initializing this could be very good or bad lol, i'll let you know if it finishes

[gentle urchin]

in construction script if that makes more sense

using actor rotation makes more sense ofc

[outer forge]

Ohh thats perfect, thanks a lot!!

[gentle urchin]

then you directly control it like a regular actor

and scale..

[spice sequoia]

Hi, I am trying to figure out a good way of plotting out my level logic for each level with objectives you complete in order/secondary objectives, triggering story events/cinematics etc - I was wondering what approaches people take to organising this in Blueprint form in a way that makes it easy to follow? Would love to see some examples if anyone was willing to share any good layouts/tricks they use - show me your tree's I guess!

[sand bloom]

it still doesn't show up for some reason

[frosty heron]

what did you type when creating the variable?

can u screen shoot your attempt

[sand bloom]

yeah only the old one(blueprint) showed up

I do still have errors in my visualstudio btw

[frosty heron]

if the build is succesfull you can ignore it

that error comes from broken intellisense

[sand bloom]

ahh okay

[frosty heron]

the build successfull tho?

i guess the best way to test it is to run it from the IDE

[sand bloom]

did a fresh one

hmm alright yeah

ill try that

I wonder if this actually will open it properly

it seemed to open it?

[sand bloom]

but still nothing i'm afraid

I do have a issue without intellisense it seems

or maybe this is just related to that

but i clicked on build only out of curiosity in the error thing

instead of build + intellisense

[frosty heron]

@sand bloom The program doesn't compile

can u show the build output

Click this instead of the error list

you are trying to build when the editor is open

[sand bloom]

no I closed unreal when I just built again

[frosty heron]

Unable to build while Live Coding is active. Exit the editor and game, or press Ctrl+Alt+F11 if iterating on code in the editor or game

[sand bloom]

oh i have had unreal closed before

but maybe my new build just now was too fast after closing

[frosty heron]

Unreal editor have to be closed before you build

2>Unable to build while Live Coding is active. Exit the editor and game, or press Ctrl+Alt+F11 if iterating on code in the editor or game

[sand bloom]

yeah i had that before

[frosty heron]

still saying that

[sand bloom]

huh?

that's.. weird

oh i guess it's still open in task manager

[frosty heron]

ctrl atl delete and make sure no editor is running

[sand bloom]

yeah i quit it now

weird

so now i'll launch from the ide again

and test again I guess

it does always bring this up

[frosty heron]

:\unreal\SurvivalHorrorProject\SurvivalHorrorProject\SurvivalHorror\Source\SurvivalHorror\Public\StructTesting.h(6): fatal error C1083: Cannot open include file: 'StructTesting.generated.': No such file or directory

[sand bloom]

but it does seem to launch it if I press yes

[frosty heron]

I think you edit the file

lets see it again

[sand bloom]

oh okay

[frosty heron]

lets see the includes

[frosty heron]

#include "StructTesting.generated.h"

missing .h

[sand bloom]

ah okay

done

[frosty heron]

build

Do you have anything on your C_Struct?

C_Struct.cpp

[sand bloom]

No that was deleted

[frosty heron]

you have to delete the file

[sand bloom]

that's what I did I thought

oh wait

c_struct

no

that was old

[frosty heron]

its still trying to compile it, so I assumed it's there

delete C_Struct.cpp

[sand bloom]

yeah mb I thought you meant my cpp file for the structtesting file

Do I also remove this from the ide

idk why it's in here

it's removed but still like a old reference maybe

[frosty heron]

I don't think StructTesting is the issue

C_Struct.cpp is the one having issue I think

[sand bloom]

fair

[frosty heron]

and MyClass possibly

[sand bloom]

yeah i deleted that one too

it was old

[frosty heron]
