[frosty heron]

so the cube actor stayed in place but the cube mesh moves.

[merry fox]

That makes sense, so what is it that I want to do? 😅 Ahhh use the mesh component's location instead??

@frosty heron thanks a million! I just used the static mesh's transform instead!! 🙏 🙏

[hardy merlin]

You want to make sure the root component is the one with physics, else you run into problems.

[merry fox]

This is the way I set it up. And I have the physics enabled on the StaticMesh. Does that look right to you? See the image below.

[hardy merlin]

Make the Box the root component instead.

And have the static mesh as a child.

Use box collision instead of static mesh collision.

[merry fox]

Yeah that makes sense too. Will do. So have the box be the collision box. If I want an overlap box does that mean I'll have to add a new collision box just for overlaps?

[hardy merlin]

Yes. But it's rare you want something that both collides and overlaps.

[merry fox]

I don't necessarily need an overlap box in this one. It was just for testing.

Ok thanks @hardy merlin

[hardy merlin]

The rule of thumb is that if it's moving, use a primitive collider (box, sphere, capsule, etc). If it's not moving, mark it static and use mesh collision.

[merry fox]

Makes sense.

[dark drum]

If you want an actor to have physics it's normally best to have the static mesh as the root. This means the actor as a whole will simulate physics instead of just the component. (All components will move with the root)

You can get some weird behaviour otherwise.

Edit: Just to add, this also allows you to control the collision based on the static mesh set.

[merry fox]

Seems like there are 2 views on this. Some like the collision volume as root, like the third person character, and others the mesh. So when you say actor, you mean non-pawn and non-character actors?

[dark drum]

Yea, that's right. Pawns/Characters often have a collision volume as the root because skeletal meshes require physics assets which are more costly to simulate than just moving a mesh around.

Having a static mesh as the root means the collision used is whats setup on the mesh its set to. If you want a cube you can still have just a cube in the specific mesh. For more complex shapes you could have 2 or 3 cuboid shapes. Depending on the game you could even go for tighter collision with custom hulls. You'd lose this control if you have a collision shape as the root.

Plus it can save you having to keep readjusting offsets so your mesh fits inside the root collision.

[stiff elk]

Anyone know what's causing this error? I'm still trying to wrap my head around soft object references, so I apologize if the fix is trivial

[spark steppe]

show the macro?!

[spark steppe]

https://tenor.com/view/i-think-i-see-the-problem-alan-cornwall-frasier-well-there's-your-issue-nicholas-lyndhurst-gif-8832423687974804656

[stiff elk]

https://tenor.com/view/audrey-hepburn-what-glasses-shades-im-listening-gif-15337165

[spark steppe]

well one option would be to set the type for the inputs/outputs to soft references of whatever that is (likely anim sequence)

[frosty heron]

what is up with the new Material editor? Where are the base color, Normal, etc?

[stiff elk]

In here?

[spark steppe]

that kind of looks like a substrate material?!

[frosty heron]

Yeah, how do I pull out the good old material?

[spark steppe]

did you check the details?

would guess that it's somewhere there on top, or you straigt up created a wrong material type 🤷

[frosty heron]

I did but can't find anything that helps. Imma just duplicate old material for now.

[spark steppe]

which UE version are you on?

[frosty heron]

5.6

all material got converted

[spark steppe]

wtf

[frosty heron]

look like this now?

[spark steppe]

even existing ones?

[frosty heron]

5.6 source version if that makes any difference

[stiff elk]

The errors in the macro are fixed, now it's giving an error from the true and false in the "select" node

[spark steppe]

reconnect your select node

so that the wildcards change to the correct type

[stiff elk]

Same error, says it's incompatible. Error only appears when select is connected to the output

[spark steppe]

save the blueprint and compile again

[stiff elk]

No luck there

[undone sequoia]

guys how to hide show widget just for specific person in game?

[dusky moat]

im abit confused, guys!
my build behaves differently then editor.
for example it loads DIFFERENT level on this button press

Im in total shok, dont know that do even think

[frosty heron]

use OpenLevel with Reference

package may have different path. Also typing is error prone, you don't want to use OpenLevel By name

[dusky moat]

it works, thnx. Any clue why instances are losing their matirial in build?

[dark drum]

You probally just need to update the type for the inputs/outputs.

Alternatively, you can make a pure function like this that should work.

[pine carbon]

Blueprint Runtime Error: "Accessed None trying to read (real) property CameraRef in BP_MinigameCharacter_C". Node: ApplyMovementInput Graph: HandleMovementInput Function: Handle Movement Input Blueprint: BP_MinigameCharacter I'm not expecting anyone to know what this means, but I would like some guidance on how to approach debugging it. There is no "BP_MinigameCharacter_C" in the outliner when I'm running this, so I'm a bit confused on what that could be.

[faint pasture]

You sure that's not the character being spawned at runtime?

[pine carbon]

When I say in the outliner, I mean in the outliner as it appears during runtime.

The character spawned at runtime is "BP_MinigameCharacter_0".

[dark drum]

'BP_MinigameCharacter_C' just refers the the class type, not a specific instance. Check how 'CameraRef' is set.

[pine carbon]

I know how it's set, and I know it's at least partially working because character movement only works when it does.

Hmm.

[lunar sleet]

Most of us here know what Accessed None means actually. Your ref is coming up as null at runtime, this usually means it is not set properly

Most people that have this issue are creating an empty var of a specific class and expecting it to just contain a valid ref, which is never the case

You’ll have to show how you set it if you need further assistance

[crimson briar]

In other words, if you had 3 character of this class, they would all throw errors with the class name BP_MinigameCharacter_C, not with their object name in the outliner _0, _1 etc

[pine carbon]

My BP_MinigameCharacter gets the camera passed to it when it is spawned so it can use it for the movement logic, such as in the HandleMovementInput function in that error. What's confusing is that the movement works.

[pine carbon]

Is there a way to get it to use their name in the outliner?

[lunar sleet]

Show how you’re passing the camera ref.

You can always add an isValid check on it or use a validated get but that will only cover up the symptoms and stop the error from showing, it won’t fix the actual issue

[crimson briar]

Dunno, it was never an issue for me. An error like this means a problem with how the class is designed, not with one instance of it. So it doesn't matter which instance is throwing it

If you want to debug you can add a Valid check as said above, and to "not valid" plug in a print with GetObjectName

[dark drum]

Is there a reason you're avoiding just showing the logic? Most of us could probably tell you the exact issue from an image or 2.

[lunar sleet]

My money is on CameraRef being just an empty variable of class BP_Camera or w/e said class is called 😀

[dusty loom]

good evenig or good day how ever you like can somebody help me fix my bluprint i am trying that my character when it hits the door that it break chaos but it always goes to the right

[pine carbon]

Current computer I'm asking from takes ages to load it, sorry. I'm getting it.

[pine carbon]

It probably is somewhere but that should only be able to happen if the player is being added with something other than this function, and I know that the one I can see when I run it is added through this.

Unless there's something drastically wrong here.

[dark drum]

And when/how does this get called?

Hi idk what happened to my gasp movement system i when i move sideways "only left and right" it does this how do i fix?

[spice cradle]

hello there

[astral summit]

I need a way to import assets into memory only when requested.
This would be easy and quick to set up if I have thousands of assets.

[crimson briar]

Look up asset manager - I don't use it myself, but I saw some people talking here about it, where they had groups of assets in bundles and loaded them as a whole bundle.
If you are talking about loading single assets whenever you need them - you use soft references and load them only when needed

[astral summit]

I've heard about asset manager, but it seems complicated to setup

[crimson briar]

Well you are making a game (I'm assuming) - it is already a complicated thing to do.

[faint pasture]

What's the situation in which they're being requested?

You probably want the soft class ref type approach

[astral summit]

The soft,It's kind of easy, but tiring if I have a lot of assets

[faint pasture]

Your system shouldn't care how many assets, you just make a system to load whatever assets are in whatever list that it gets from wherever and it does it

What are you actually trying to do here, what's the actual game mechanic problem?

[astral summit]

I have a UI-only game. The problem is that when opening a level, there is a delay because it loads all the assets at the same time.
If I wanted to convert assets to soft variables and load them when needed, this would be tedious because each asset needs to be changed and a loading function installed when needed. This is tiring, may cause programming errors, and takes time to set up everything.

[faint pasture]

How is the level that big and why aren't you using world partition if it's that big?

https://dev.epicgames.com/documentation/en-us/unreal-engine/world-partition-in-unreal-engine

[astral summit]

My game is UI only, meaning it uses only images and texts without a 3D world.

[faint pasture]

Yeah your chain of hard refs has bitten you in the ass

They are being loaded into memory when requested, you're just requesting the whole thing as soon as you load the lvel

a hard ref IS a request to have it loaded

[knotty current]

need emergency help: CAN PROVIDE SCREENSHOTS OR ELABORATE IF NECESSARY

in my game, there is a trace thats runs the interaction. it should be that when a player interacts wiuth another, the focused one is moved back a tiny bit. this partially works, but i find that the focused player is often scrambled. when one actor interacts with another, it might work OR it might move themself or even a completely random player. please help, i need to get this done asap or else i will be a big troublea

[astral summit]

Nothing bit me, but you get the point. What do you think is the right solution?

[faint pasture]

To build into whatever is your common base class the ability to load it's referenced children only when actually needed.
I'm guessing you have something akin to a visual novel with some structure like scenes and dialogues etc.

[faint pasture]

show code

[knotty current]

Ok

A moment

[trim matrix]

i now have it to where if theres a question mark, the buttons appear, now im stuck at binding the on clicked for the buttons to set the next line of dialogue depending on what the player was asked in the original line

[knotty current]

@faint pasture

i know some of its not optimized and messy but really just trying to fix some stuff.

and by the way, "trace" function in "AC_InteractionTrace" runs on event tick

[astral summit]

I feel like Asset Management is the right solution, but damn it seems difficult to understand and set up.

[faint pasture]

holy shit that's a mess lmao

where is TryToInteract?

[knotty current]

I know I’ve been trying to fix this fuckass software for an hour

[knotty current]

BP first person character

Upon left mouse click

[faint pasture]

Why do you have all these weird cases?

What actors can initiate interaction, and what can they interact with?

[knotty current]

BP first person character is the only one able to do interaction as it’s the only one doing the trace.

Only actors with “BP_InteractionArea” embedded within their actor (it’s a physical cube that is hit by the trace) can be interacted with

[faint pasture]

That's a component right, effectively a component that tags the owner as being able to be interacted with?

[knotty current]

I was trying to fix the errors. If the object u want to interact with is a character, then it will run on server and interact with another player, but if the cast fails, it means its another object which doesn’t need to be ran on server to interact and therefore will do its own, non replicated function

[faint pasture]

Show a clip of what's meant to happen when you interact

I'm guessing this is like WoW where many people can talk to a quest giver

[knotty current]

It’s an actor. There is also an Ac_interaction trace, I tried to include the title of each object in the screenshots. AC interaction is what runs the bulk ofo stuff, it runs the trace, detects hit actors, finds that actors respective interaction area box, then uses it to find the parent actor to do interaction

Not sure if what I said makes sense

[knotty current]

Ok

[faint pasture]

That sounds way bigger and more complicated than it has to be

You can put all of this into a single component that you put on everyone that can interact OR be a target of interaction

[knotty current]

Ignore how crappy the actual interactions are (speed of punch and the non working widget), those are not really perfected and are just there to see if it works

[faint pasture]

So your 2 cases are a local interaction (other clients don't see anything) and a global interaction (everyone sees the same result) right?

[knotty current]

Pre t

Correct*

[knotty current]

Really? I could try that, but would it even fix the issue of the wrong players being punched when it’s supposed to be another

[faint pasture]

The get player character 0 certainly has a smell to it

[livid island]

hey so I'm trying to do a mechanic where the magnitude is increased by how long a button is held. I've tried a While Loop based on tutorials, but I can't seem to avoid the infinite crash. I also tried "Get Button Press Duration" on the button's Release node, but it only ever returns 0.0, I assume because when checked it's already set back to 0.

Anyone have a good current method of setting a Float according to button press length?

[knotty current]

Well, I mean it’s not like it doesn’t work at all. And I found the issue isuing print texts. Sometimes “focused actor”, which is used to determine focused interaction area, is set on the wrong actor for some reason. For example, when A is looking at B, focused actor might be set on A or C

[faint pasture]

Press -> record time
Release -> record time -> do math on finish - start

[livid island]

Okay I'll give that a shot. Thanks!

[faint pasture]

You can make it this simple:

Character:
Input -> InteractionComponent.TryInteract

InteractionComponent:
TryInteract -> trace -> found something -> is it owned by a char? -> yes -> run on server event passing over component ref (target's)
-> no -> call Interact on TargetComponent
RunOnServer(targetcomponentref) -> call Interact on TargetComponent

Interact -> set OtherComponentWeAreInteractingWith for both interaction components (self and other)

OnRep_OtherComponentWeAreInteractingWith -> do the actual logic

the bit that actually triggers anything visible is the onrep, in BP it's basically an OnPropertyChanged function

In that onrep, you know who you are interacting with, and can initiate whatever code there.

But the whole local/global split is pretty complicated, I'd get the global case working first then add the local

[knotty current]

Wait, so you’re saying to combine my AC_Interaction trace (actor component embedded in each player) with the BP_interactionArea (the box on all interactable actors) into one?

Wouldn’t that then result in all actors running a trace?

[knotty current]

So I should run my trace after a player tries to interact. Right now I have trace running on event tick, constantly changing the focused actor

[faint pasture]

You can only trace if locally controlled, or gate it however you want.

If interaction only happens on an input then you don't need to trace every frame unless you want highlighting or whatever

[knotty current]

I see

[faint pasture]

either way there's ways for the component to know if it should be looking around or just sitting there waiting for a call

[knotty current]

Let me try to join some stuff up and see from there if it works

[faint pasture]

If you need a trace every frame the only one that should be doing that is the one who's owner is locally controlled.

I don't want your character tracing on my screen, just my own.

[knotty current]

Yes, it was that way before

Since each character has its own unique AC_interaction trace

[faint pasture]

Why are you tracing every frame anyway, highlighting?

[knotty current]

What the YT tutorial did lmao, and yea he set up highlitiny so max sense

[faint pasture]

Get comfy with dispatchers too

you want a dispatcher so the component can tell its owning actor that it got interacted with

[knotty current]

But I can remove that, don’t need highlighting right now and if I do then it’s not hard to change

[knotty current]

What’s a dispatcher

Is that the little red square in h th e top right of a custom event

[faint pasture]

https://dev.epicgames.com/documentation/en-us/unreal-engine/event-dispatchers-in-unreal-engine

You know how meshes have Event Hit on them so you can do stuff when they get hit?

Your InteractionComponent can have Event InteractionStart so their owning actor can do things when they get interacted with.

That's the best way to do it IMO

OnRep_OtherComponentWeAreInteractingWith is just there to call InteractionStart and InteractionStop

that way it's stateful, the state, which is WHICH component you are interacting with (or none) is what triggers the start and stop

[knotty current]

Ok. I’ll try doing some of that, if it doesn’t work, do you mind if I ping you? If not I can always wait for another response

[faint pasture]

Component:
OnRep_OtherComponentWeAreInteractingWith -> other component is empty -> call dispatcher InteractionStop

Character:
Component.OnInteractionStop -> do whatever stopping an interaction means (put camera back, restore controls, whatever)

Basically the component handles it all, and the owning actor just sits there and does stuff when InteractionStart and InteractionStop fire

[knotty current]

When you call the dispatch, how do the other actors know which one of them the dispatch is for?

[faint pasture]

The dispatcher ONLY talks to the owning actor

calling the dispatcher is how the component notifies its owning actor that interaction has started/stopped

I suppose other actors could bind to it

maybe if actor B wanted to know when actor A was interacted with

Door and button

Yeah say it was a door and button

Button has the interaction component, and both door and button bind to it.

When you interact with the button, the button animates, and the door opens.

Button:
OnBeginInteraction -> animate

Door:
On Button's BeginInteraction -> toggle open or closed

importantly, you as a character don't care

you just look at the button and press E and it does its thing

Door would have to have a ref to Button, but button wouldn't have a care in the world. It's only job is to animate when iteracted with, it doesn't give a shit about anything else.

That's one example but you'd mostly just want an actor to know about its own InteractionComponents state

[knotty current]

So let’s say my BP character is made up of 3 parts, invisible box, mesh, camera. In this case, would I write in the invincible boxes code that when it is traced, it calls a dispatch that affects the rest of the actor?

How does a dispatch differ from a function or a cast to object+functuob

[faint pasture]

Assuming the box is your InteractionComponent?

so it's a box + other stuff you'd add?

[knotty current]

It’s a Box with code. In my case it’s “BP_interaction area”. That’s all that BP is. An invisible actor that calls to trace

[faint pasture]

Why are you tracign if you have a box?

that makes no sense

or are you tracing to see if you hit a box

is the box the target or the area being checked?

[knotty current]

Yes

I am tracing to see if I hit a box

[faint pasture]

yeah box sphere whatever it doesn't matter

[faint pasture]

In this example, your component would do a trace and see if it hit any other interactioncomponents

if it did, you kick off an interaction between self (your component) and the other

it's just components talking to each other until the dispatcher is fired, then the actors know

the advantage to having a dispatcher instead of casting owner to some class is that you don't care what the owner is

you don't care if it's a character or a vending machine or a button

the interactioncomponent is just shouting into the void "hey we're interacting here" and whoever is listening (bound to the dispatcher) does whatever

[trim matrix]

ik id need to set the current dialogue int to the correct line in the dialogue array depending on what button the player clicks, but im not sure what id need to do to do that, and also have the rest of my increment speech continue,

[knotty current]

I’ll try some stuff out I suppose. How do I make a distance?

Dispatch

Oh I see

What exactly would I do here

This is just a test but what would any of these mean?

@faint pasture

[dusky cobalt]

you have everything in front of your eyes that you need to google and gain knowledge, nothing rocket science so just reading what these do will probably give you anserw, if not then ask

[faint pasture]

select the component inside your actor

on the bottom of details you'll see a bunch of dispatchers you can implement events for

[whole ridge]

Hey all! Hope everyones Monday is going well!

[knotty current]

heres the thing. the seperate box actor is also there to act to find widgets

\

it builds the widget for each interaction

[faint pasture]

You don't need that

the one trace can be used for everything

focus interface -> that can be part of an interaction widget

if you mean for focusing to be "the thing you'll interact with if you press the button"

[knotty current]

my dispatch has now made it so it never even runs the code 🙁

also, i remembered why my trace was on event tick. it was to trakc the widgets

[faint pasture]

yeah that's fine, you can still do that

just give the interactioncomponent a variable that represents the "highlighted" interaction component and handle it all with that

[knotty current]

and it has

[faint pasture]

give InteractionComponent a variable to store the widget class to show when it gets highlighted

[knotty current]

it has that

are u sure the event dispatch stuff is gonna fix the issue of the focused actor being all jumbled

[faint pasture]

If you have a nice clean tight design that all lives in one spot, it's a lot easier to make sure it works than a design that has components, actors, interfaces, and other stuff all over the place

[knotty current]

yea i guess

its still not gonna fix my issue tho

im not even sure why its happening. dont get why the focused actor is getting mixed up. its really getting on my nerves how long its taking me to get over this.

ughghghughghhghg im genuinely gonna lose it

[faint pasture]

show where focused actor gets set

[surreal wagon]

I have this issue where I need to know if the trace item changed properties, how can I achieve this?

[brisk pine]

you mean when the traced item changes from table to money?

[surreal wagon]

Yea

[brisk pine]

not sure if the money is blocking the trace line or not, but you can check if the currently traced item is equal to the previous traced item, and if not, hide the ui for the previous traced item and show it for the new one

I mean does it hit the money and then the table, or does it fully block it?

[surreal wagon]

Can't seem to get it right man

I believe the issue lies before this function

[outer sparrow]

hi there! I'm having some issues with pitch camera control

My camera would only move horizontally, no vertical

Can you help me please?

[spark steppe]

the action value might be in X

also it's a little weird that you get 2 values, did you define the IA correct?

should be scalar if you just "capture" one axis

[tawny hedge]

is there a way for substring search with gameplay tags as in class.subclass.type and only get matches by type regardless of class.subclass?

As far as I've seen there isn't one which seems to be an oversight for a system like gameplay tags

[crimson briar]

You could make your own function to split it on the dots and return the last string from the array. But it seems like you would be misusing the tags. ClassA.SubclassA.Type and ClassB.CubclassB.Type should relate to different things, equating only the .Type seems weird

[real cedar]

i got a question for you ,you know how we pause a game using escape and unpause using esc only. Can you tell me how to implement this system you see i can unpause using resume button but you know the rest

[tawny hedge]

I have let's say Item.Slot.Body.Cloth and Item.Slot.Feet.Cloth and other types for Main Hand for example. I don't want to run checks on each individual slot and I don't want to separate slot from type as I use it for other stuff. I was also thinking to break into string and query somehow that way

[crimson briar]

Why won't you have something like Item.Material.Cloth and Item.Slot.Body? You give the item those two tags. That is the power of the tags, you can have multiple depending on what you need. Making everything into a single tag line is going to cause problems.

But as I said, if you REALLY want to keep it like this, make your function for it. You convert the tag to a string (there is a node for that) then do a split on the dot sign. Then you can either use the last entry of the resulting array or compare against any tag part in the array, depending what you need it for

[spark steppe]

make a matches all on the parent tags X.Y and combine it with another matches X.Y.Z

[tawny hedge]

I was thinking about that but I still see having the option to search for subtypes only way more efficient than creating more abstract stuff in terms of hierarchy. Your suggestion was my main to go option but still trying to find a workaround.

[little moat]

Alright I got a question

So I got a custom avoidance system

I'm currently using my AI controller to store the future locations of the NPC's. But should I rather just store future location for each NPC in the NPC and use the NPC's array to get that variable instead of using an array in the controller for them all?

[faint pasture]

Depends on philosophy really. I'd say the future locations or path is a property of the mind (controller) rather than the body (pawn)

[little moat]

Hmmm

Yeah makes sense

All roads lead to rome

[winged zephyr]

My Gameplay Camera Rig doesn't move when I update the variable this way, how am I suppose to use it?

[undone sequoia]

Guys I need tip with propably easy problem but I Dont know how to solve it I have widget on ENEMY PLAYER , I want show this widget for one player in game but for another player in same time i want it to be hidden, problem is when i make visible this widget all players in game see it but I want only one player to make see it

[crimson briar]

I would recommend not using a widget component like this in a multiplayer setting. Instead create the widget for each player locally and then manage it's visibility/content locally

[undone sequoia]

at first it was made for singleplayer works good but in coop it is not working its widget component yea

its because when u make widget for each player its harder to align and move it with player this is always attached with precision on player

so thats why i used widget component

[crimson briar]

Singleplayer and multiplayer require different approaches, that is all there is to it. Widgets in general should be handled by the client in most cases (outside of a few world widgets where necessary), since they are only a method of displaying information to the player.
You could try to disable replication on the widget component and manually change the values with RPC or dispatchers connected to replicated values - then the clients can freely turn the visibility on/off on their local proxy. But it is not a good way to do it, I think

A well made Health tracking widget would only require the player/controller to tell it "Hey I'm pointing at ActorX" and it would handle positioning itself

[undone sequoia]

gonna try something thx

i thought maybe unreal has some posibility

to turn on turn off widgets for anyone

not for all at once

[crimson briar]

If the widget component is not set to be replicated, you will be able to change it only on one client - at least you should, it works like this with actors etc, I haven't tried it with the widget component in particular.
But then if you want some information inside it that is sent from the server, you need to do a workaround, like using a multicast so each client proxy updates their own widget

Although maybe things like "HiddenInGame" are not replicated by default since it is a rendering thing. You could experiment to see if it works. But you need to try to hide/show it from the client, not from the server

[undone sequoia]

i am trying yea

[severe bay]

I cannot figure out what I'm doing wrong with my UI. Here's a rundown:

I'm working with a UI for my game. The UI worked binding functions to the aspects I wanted to change; however, almost every element in my UI has very few instances during play where it needs to be updated. I want to do this more efficiently.

So I went with a blueprint interface that would send a message to the UI widget blueprint as necessary. Then I have a function behind the event to set the brush for the item I want to change.

As an example, this is how I'm doing updating the keycard (when all enemies are defeated, the player is awarded a keycard that allows them to exit the level).

-When the game starts, the game mode calls interface "KeycardIconUpdate" targeting the HUD.
-UI_GameOverlay received message and runs function which attempts to update the image of the keycard.
-The keycard image remains blank.

I've verified that the logic is working in that the interface successfully executes and that the execution is passing through the brush creation/set nodes. I've verified that the image is set to variable.

I've searched various forums and whatnot, but I've not come across anything yet that's helped. Any assistance would be appreciated.

[crimson briar]

Okay, maybe I overcomplicated it a little, sorry. I just remembered I have a widget like this in one of my projects. In my case the character manages what happens with the widget, but it is all local. Server comes in only by updating the repnotify variable with the widget content that is on the character

[undone sequoia]

hm weird i tried it like this with hidde and its still showing for all i even trried run it via executes on owning client

hmm

[dark drum]

Unless you plan to have different versions of the UI (that don't derive from the same parent class), you're over using interfaces which is probably messing you up. Interfaces still require a valid ref to the target which is most likely where you're tripping up.

However, with something like this I would use an event dispatcher. When the keycard is given to the player it can call an event dispatcher 'OnKeycardRecieved'. This will allow multiple things (such as the UI) to listen to this event and do its own thing when called. (In this case, update the icon)

[severe bay]

Noted. I can change it to an ED. I just personally like how I can logically group together multiple types of calls (like all UI update calls) within one interface. However, I have confirmed that the interface is still being called as expected, so the issue of not changing the brush, I expect, would still persist.

[crimson briar]

Is your component replicated? Mine is not, the first screenshot shows only the variables that are changed from the default.

[dark drum]

How have you confirmed its being called?

[severe bay]

Just printing strings within the execution threads around the brush creation/set.

[undone sequoia]

not it is not but mine widget is spawned with NPC Player at the start of game and when I am in game with other players it is existing on server with npc so when I tell from one player to hide it or show its switching on server so everyone sees it because there is only one instance on NPC only on server propably this is problem i would need create widget locally and attach it to ncp propably ahhhhh but i had it before and it didnt look good 🙁

it was not good aligned and was changing its size

[real cedar]

anyone know the solution i know it is basic

but still

[dark drum]

If the set brush nodes are being called there's no reason it wouldn't update. Can you show how you call the interface function?

[crimson briar]

Spawned how? Begin play, inside a component, Server RPC?

[dark drum]

Also, event dispatchers are your friend when you have multiple things that might need to do something when something else happens. 🙂 Saves you having to keep a list of different things to call an interface function on.

[severe bay]

These are within game mode in the "Begin Play" event. This is to initialize the UI graphic.

[severe bay]

I'll work on using them more.

[undone sequoia]

its part of npc tree

npc is spawning with it

and i just toggle hide/unhide

or i change colors etc

it has like 3 states and is changing when locked when near etc

[severe bay]

This is what the graphic looks like (white square under the 3 hearts):

[dark drum]

Show how you've setup the 'Keycard Icon Update' function.

[severe bay]

I removed it from a function for now to simplify things. This is the current logic:

[crimson briar]

It should still work. Even if you spawn the NPC on the server, if it is replicated, the proxy is created on the clients. Proxies are created from the class, so they will have the widget - only it won't be connected to the server version, it will be it's own local thing.
So you probably interact with it in a wrong way, making it change everywhere, not only locally

[undone sequoia]

I have widget set as not replicated and i am calling this from event tick , while entry from my interface is my widget i dont see any problem 🙁

now test shows orange square on both clients

[dark drum]

If you add a breakpoint to the branch node, when you start playing does it jump to the node?

[severe bay]

It does.

Just for kicks and giggles.

[dark drum]

step through until it gets to a 'set brush' node and hover over the 'Keycard Icon' var and see if its valid.

[severe bay]

Copy

[severe bay]

It appears to be valid.

[dark drum]

Is the brush/image set anywhere else in your logic?

[crimson briar]

I'm not sure why, maybe I'm not understanding something but this code looks cursed. But it definitely doesn't show the full picture how, when and what changes the targets

[severe bay]

I'm going to double check that. I don't think so.

[undone sequoia]

cursed hah thx

its just going from event tick gets all actors with interface homing (means all who have this widget so I can aim on them)

then i take this reference and show it for player which is using homing gun

thats all

[crimson briar]

I mean, you are using a pin from the server code, inside an Owning Client Only? And if the code below is not server only, why is it calling Owning CLient Only event?

[undone sequoia]

i am using pin from event tick so basically its calling server/client i can try put there switch authority maybe

ok same output

i am lost

[severe bay]

There's nowhere else that I'm updating the keycard from that I can find.

[dark drum]

The only other thing I can think of to try is using the 'Set Brush From Image' function.

[crimson briar]

Okay, I can only guess, since you didn't show everything.
OwningClient RPC should be called only from the server. If it is not in your case, this is already wrong - it probably doesn't do anything when called from other places.
Secondly, if this code at the bottom is from the server side, you CAN'T connect anything from it to the other RPC. Because even though the code is in the same blueprint, they will be ran on different instances. The owning client rpc will have a null from the blue pin.
But if you want to do it locally, you shouldn't send a reference to a widget - since they will be unrelated, a widget from the server won't be the same as the widget on the client. Instead you should send some data that can later be used inside the RPC execution (or repnotify) to change the visibility of the widgets
Or to do it fully locally, don't use any rpcs at all

[severe bay]

Is that function under a different name perhaps? There's asset, material, sprite, and texture I can make the brush from. I tried to set the brush from resource object and still no go. Just to make sure I'm not updating it from some weird place I've forgotten, is there a quick way to see what's updating that element?

[severe bay]

I had initially tried that first. I did try it again just now just in case and still no go.

[severe bay]

Outside of having the UI element being variable, are there any other settings that are important to being able to change the slatebrush programmatically?

Maybe I could check those.

Oh no. I might have found the issue. Let me see something.

I've discovered the issue. I had created the UI on the map's BeginPlay. I forgot to delete that when I moved it all to game mode. I had two UI's being displayed.

Thanks for walking through this with me, Patty.

[dark drum]

Glad you figured it out.

[severe bay]

I think I was just getting too frustrated to think clearly, so I appreciate you being there.

[dark drum]

We've all been there lol.

[woven pond]

Is it possible to use an actor component to change the parents collision setting? (I can only seem to enable/disable from get owner using 'set actor enable collision').

I was hoping to use an actor component to change the owner/partent capsule collision response on a custom channel 'Interact'

unless im searching for the wrong thing and should be looking at an interface to get the component?

[dark drum]

Something like this. This would only work on the root component though but if it's the capsule of a character, you should be fine.

[cunning vapor]

Heya !
Probably a simple workaround that im not doing but; i think may be a simple solution.

Ive made "Gatherable Spawn Points" with an enum variable to chose what spawns

My question is; what would be the best way to spawn in a random spawn point (only on the spawn points that are set as the correct enum) and not to double up on the spawn points; currently using integers but am curious if a temp array of integres to cross reference would be the best way to not double up

[woven pond]

@cunning vapor convert the enum to an int and get max number of entries and do random int in range and get the entry at that index?

well thats at a guess I could be wrong but thats where id start

[woven pond]

thank you, ill give it a look after i try an interface

[dark drum]

Im not sure of the question.

[cunning vapor]

sorry; its pretty poorly worded:
basicaly im spawning something at an array index at random (to get a random spawn point position) and want it so that it wont double up and spawn twice in the same spot

[dark drum]

Create a function that creates its own copy of the spawn points (could be passed in), get a spawn point from the copy and remove it when done. Rinse and repeat until x amount has been spawned or the array becomes empty.

[cunning vapor]

thats perfect; thanks Patty

[chilly grotto]

Hi! I rarely talk here but today i was forced to lol!
so i have created a child blueprint of my enemyboss_bp
everything is fine except when i retarget the animation blueprint, and use it the child doesn't die after 0 health its still alive. However if i use the default anim blupeprint without retargeting (which i cant because it deforms the mesh)it dies and everything is fine!
also that the retargeted anim blueprint inherits everything from default one.
i still dont get why its not working

[lunar sleet]

Use breakpoints to find out where the code stops working so you can debug from there @chilly grotto

https://streamable.com/86bu79

does anyone know what happened to my gasp movement system i when i move sideways "only left and right" it does this how do i fix?

[cunning vapor]

Reckon it's not working because it's a local variable or some oversight of mine ? Actor is being removed from the array but still can be spawned at the same transform location @dark drum

It was an oversight of not setting a current variable 😛 my bad

[faint pasture]

instead make an actor with the homingtargetindicator in it and spawn it LOCALLY on the computer that wants to see it

The attacker should spawn HomingTargetIndicator and attach it to the thing they are targetting, and handle getting rid of it etc.

[dark drum]

As an FYI, it'll remove a different element than the one used to spawn. This is because the random node is a pure node and will be re-evaluated when it gets to the remove node.

You can cache this as a local var and use that for anything else down the execution chain.

Alternatively, (my favourite solution) you can just shuffle the array copy and just get/remove the first element (0).

[cunning vapor]

Got it working with a local var, but am going to try:

[north bobcat]

how would I make one of these?

[faint pasture]

shader

shader with a SliderAlpha parameter that goes 0-1

[north bobcat]

why a shader

[faint pasture]

because it'd be piss easy and take like 1 minute to make.

Just feed it 2 textures, and the output is a lerp between the textures driven by if U (from UV) is > SliderAlpha

[north bobcat]

what

I mean why a material and not just in the widget

[faint pasture]

You could do it in a widget but I'd guess it'd be more trouble, but sure

2 progress bars both visible

why progress bars

[maiden helm]

I have this Blueprint issue that I can't resolve, I also tried ChatGPT but is hard to understand. What I am trying to achieve is in VR when I grab some Tagged object I can relocate them in the room but when you push the trigger button in the controller the object will snap to the surface. (Wall Floor) I have this custom function that will be called on the VR game template for unreal 5.3

the issue now is when I click the trigger all objects jump to the controller LOL and a random object is pushed agains the selected wall.

your help is very appreciated

ChatGPT was offering other solution using any overlapping object, but I really didn't understand it code

[faint pasture]

the computer is doing eactly what you are telling it to do

look at your first node

get ALL actors with tag

then you do the following code to ALL of them

Here's how you want to set it up, it needs to be a few bits of code.
First bit does a trace or some other check to discover objects, and chooses one to grab that has the tag. It sets actor ref GrabbedObject
2nd bit is on tick, you cook up a TargetPosition (which is usually the hand position) and then you move the grabbed object (if valid) there.

to do the snapping, just change how TargetPosition is cooked up

To reiterate, have grab/ungrab events which result in setting and unsetting GrabbedObject

On tick, if GrabbedObject is valid, cook up a target transform (based on if in snapping mode or not) and move the grabbed object there.

[maiden helm]

the computer is doing eactly what you

[steep oyster]

My first question would be, if implementing something this complicated is even worth the trouble

[thin panther]

Given the posted video it doesn't seem all that complicated :P

[steep oyster]

Thats an image

Not shaders

And why do you insult me as stupid, act cocky and then dont solve the problem

[faint pasture]

just copy what I did, just replace what goes into the A pin on the comparison with a scalar parameter, and set the parameter from whatever code you want (in a widget or wherever)

Materials work in the UV space, U is your horizontal, and V is your vertical. What that material is doing is choosing which image to show on the output based on if U is > or < than the parameter. So to the left of the parameter, it shows one texture, to the right, it shows the other.

[dusky cobalt]

Is there any way to have 1 widget and display it in 3 places? not really right? i have to create 3 widgets if I need it in 3 places?

you mean like instanced widgets?

yeah but I just anserwed it in my question haha just need to create that many instances

[steep oyster]

But what could someone possible need this for?

We have solved the how, but sometimes, you gotta ask the why. After almost 4 years of Unreal, I learned, redirecting your ressources saves time and energy

Back with camera issue, now with access to the offending code again. The reference to camera gets lost during the loop for reasons I do not understand.

This will print the camera's name.

This will not.

Checked this out of curiosity, this ALSO doesn't print the camera's name.

I'm not entirely certain how my player is able to move since they shouldn't be able to move relative to the camera without getting this reference.

[faint pasture]

are you sure players has any entries at all?

I have a level that's working well, so naturally I want to make more. I Duplicated the first level, then made a child class of my 2D Camera so I could give it different parallax backgrounds. Problem is, when I replace the original camera with the child class camera, it lacks the Boundaries. I go to play the new level and the camera, while centered about the player, is showing empty space underneath and to the side of the player.
It's so maddening bc you'd think an identical duplicate would function identically, but it doesn't

[faint pasture]

why does that top execution path pull a bool from a completely different event (which may not have run yet)?

[hardy merlin]

Does anyone know where I can get debugging leveldesign textures such as grids and rings?

remove your scalar modifiers and for W/D add a swizzle modifier

can someone confirm to me if this person is right ??

so my knowladge is when a tile in world composition is loaded so player is within tile bounds everything in that tile is loaded into memory

Hi, i don't want the size to change based on text length. How can i make this a fixed size?

There's nothing with "Size to content" enabled

you can use scale box I believe, I dont think there's a sizetofit or something like that for text in unreal engine

Hello,
Does anyone here know how to use the Asset Manager to divide files into chunks for the Google Play Console? I tried, but I’m still getting the error that my module exceeds the 200 MB limit. It would be really helpful if someone with experience could guide me on this.

[fiery flower]

Either it didn't work, or i'm using it wrong. Not sure. Nothing's changing

[last peak]

you are using it wrong

with umg always remember this

the parent is always the wrapper f or the child

border is wrapper for vert box

vert box is wrapper for scale box

scale box for horizontal

horizontal for button

and i assume button for text?

[fiery flower]

yes

[last peak]

you can put a scale box on the button then the text as child under the scale box

a size box could work too you can hardcode the size then

[fiery flower]

@last peak Is it correct now?

[last peak]

yes the hirarchy is correct but if it doesnt behave like you want replace the scale box with a size box and try to hardcode a value

[fiery flower]

I only replaced the main ScaleBox with a SizeBox, didn't work. Left the main ScaleBox as is and changed the others to SizeBox, still didn't work. But i found the parameter that gives the behavior i was looking for: Min Desired Width (and Justification)
This is enough for now

Thank you @last peak , @brisk pine

[last peak]

thats what i meant when i said try to hardcode a value
Sorry should have specified that

[simple shale]

Hey there !
I'm an Unreal Beginner and I've just finished making my first movement system (Following the tutorial in the docs) with animations.

The thing is, the character model goes all shaky whenever I walk backwards and seems to shake a little when I walk on any other direction than forward

Did anyone ever face a similar/the same issue ?

[faint pasture]

probably your blend space

walking backward it's flicking between 180 and -180 yaw

[simple shale]

yeah but I don't get it

it's the exact same as the tuto

[faint pasture]

almost all tutorials are shit

show your blend space

[simple shale]

gimme a few I'm on valorant now 😭

[full badge]

i switched to dot product velocity and forward/right vector, that solves it

[faint pasture]

yup that's the ticket, it's a much better system

[simple shale]

damn .mkv

[simple shale]

where's that ?

[faint pasture]

instead of your blend space being speed vs angle

make it ForwardSpeed and RightSpeed

with idle in the center

[trim matrix]

its just a macro

or which path do u mean

[simple shale]

so smth like this ?

[faint pasture]

dot product between velocity and right vector is how fast you're going to the right

same with forward

what you just posted will always be of length 1, not very useful

[faint pasture]

I meant the float that is indeterminate if the top event runs before the bottom one

[trim matrix]

its to make sure the text box stays on screen the duration it takes for the message to fill on screen, then wait 2 seconds before setting visibility

[faint pasture]

Yeah so what's the value of the pin if the top event runs before the bottom one does?

don't pull value pins all over the place, use variables.

[simple shale]

This should be fine ?

[faint pasture]

no

that will always be of length 1

[simple shale]

😭

[faint pasture]

you want the dot product between velocity and right vector

[trim matrix]

ok ill set it to a variable n then plug that in

[simple shale]

wait

it didn't

ss

my thing

[faint pasture]

or just unrotate velocity and break out its x and y components

which will get you the same answer

[trim matrix]

still dont know what id do for the rest of it

[faint pasture]

Right speed is correct, forward is still goofy

[simple shale]

What's it supposed to be ?

[faint pasture]

dot of velocity and forward gives forward speed

dot of velocity and right gives right speed

ik id need to set the current dialogue int to the correct line in the dialogue array depending on what button the player clicks, but im not sure what id need to do to do that, and also have the rest of my increment speech continue,

[simple shale]

If that's correct, what do I do with this now ?

[faint pasture]

fill out your blend space with the poses where you want them

Idle is at 0,0, go from there

looks like sprint is at 0,1000
forward is at 0,500
idle is at 0,0
backward is at 0,-500
right is at 500,0
left is at -500,0
etc

[full badge]

change the min/max of both axis to -1000,1000

[simple shale]

Won't let me 😭

[faint pasture]

you literally can't type -1000 there?

[simple shale]

nope

[trim matrix]

any ideas on what i should do for this?

[last peak]

How could anyone know without seeing your code ?

[trim matrix]

ive sent the code many times already

this has been ongoing for a few days atp of me asking

[dusky cobalt]

If I can recommend you anything, is to get paper and pen, forget about EVERYTHING that you have in blueprints and start from 0. Write semi-code on paper what should happen. This isn't complicated. It's literally event driven. The second feedback - fix the look of it. Are you that lazy that for 3 days it looks the same mess? Really use comments, comment what does what and why. A nd then you could also be more precise about what is happening and what you need to happen. But i'm sure if you started with pen and paper you would fix it in 1h.

[trim matrix]

Btw it is nice to do a thread if the problem solving continues for a longer time, easier to find what was going on then

[trim matrix]

ive said idk how many times im confused and trying to understand

[trim matrix]

i can make a thread

[trim matrix]

i mean.. ive sent the same thing. same screenshots multiple times. so yea i am repeating myself atp

even specifically said where i was stuck at😭

[simple shale]

Yet you have to understand that people to this volunteerly in their free time, they aren't robots and won't always know what's going on w you

[trim matrix]

im aware. which is why ive asked multiple times.. attempted to understand what im coding.

no one said they are robots lmfao

[lunar sleet]

I believe there are dialogue plugins that do all of this for you already

[trim matrix]

ive already started coding this and adding into my game atp i rly dont have the time to rip it out and use a plugin instead

[simple shale]

Would probably be a thousand times easier than fixing said code though

[last peak]

Hehe and if you want anything changed in the plugin you are fked if you dont even understand the basics ^^

[lunar sleet]

Granted, but I just figured I’d offer the option 😀

[trim matrix]

exactly, thats tbe other reason i dont want to rely on a plugin

[crimson briar]

Sometimes you just have to scrap something and start from zero when it gets too unwieldy. Especially when you are still learning

[trim matrix]

literaly the only issue rn is the buttons. and setting the next line of dialogue based on which is clicked and having the increment speech function run again. bc if it does it will run normally bc the check to make the buttons appear is checking for a “?” in the dialogue line, if not continues

[trim matrix]

im aware. and have already w my other games. i dont rly have the time for that w this one like ive said

[dark drum]

So you want branching dialogue trees? Where the dialogue can change based on the options the player provides?

If so, how are you storing the data for the dialogue?

[last peak]

Would be so much easier if we could see the code XD

So far everyone that wrote here so far could have solved it with the code

[trim matrix]

in an array of strings, each line is in the array

[dark drum]

So there's no data to indicate what line it should go to based on the option picked?

[trim matrix]

theres a int variable to tell which line is being spoken thats it. ive been stuck past this

[dark drum]

That's possibly why you're struggling. Branching dialogue can be a data structure nightmare.

You'd need something to denote the options and what line/dialogue it should go too if picked.

If this isn't something you've already thought about, you may end up having to redo large portions of your code to accommodate it.

[trim matrix]

so i could make a struct to hold the string of dialogue and what index to set it to?

ive thought about it to the extent that ik i only want there to be two possible options, yes or no, and theres only two questions that can be asked as well

this npc dialogue is rly limited in my game by design

[dark drum]

Potentially, possibly an array of ints though to denote each line that it could go to based on the option selected by the player.

If it helps, I have done a BP only dialogue system tutorial series that handles branched dialogue. You assemble the dialogue in the graph editor (like you would any logic) so it can be easier to manage. There are of course pros and cons.

It might give you some ideas on how to tackle it.

[trim matrix]

possibly, im just trying to not have to make the logic overly expansive if it dosnt have to be. like the npc only being able to ask two questions is bc i want them to ask if the player wants to accept their request of an item, then after they have the npc asks a question again if the player has the item

the npc just dosnt have many usecases in the game bc they are a side thing

[dark drum]

If it helps, the series has 6 episodes and the core system is the first 3 episodes totaling about 90 mins lol. The other parts are extras like audio, animations and saving

[last peak]

What is it that you want now exactly?

here you check for last index

Then you end dialogue

You want to display different text based on your answers ?

[trim matrix]

ive already said it😭😭😭 i want when the buttons are on screen to have which ever one is clicked set the next line of dialogue depending on the button (for example press yes, set dialogue to line 7. press no set dialogue to line 8.) rn i have it working if its not a question. if its a question the buttons appear. i am stuck on having the buttons assign the next line of dialogue and then have the increment speech function run again, bc after the button sets the npc dialogue to the corresponding line. it wont be a question anymore and should continue w the code i have thats working

I need to have a return value on my function, I can't really put it in the event graph ? Because I need to call on the completed pin

[last peak]

You can call a event that calls async load

from inside the function

[trim matrix]

so am i just gutting this? or can i finish it and add questions into it. bc thats litteraly all i have left to finish on the npc dialogue

[short panther]

And how can I use the loaded value in the function afterwards ? I dont really see how I can do it sorry 😬

[trim matrix]

bc i already have it working to a point i dont really want to break

[last peak]

Save it as variable

[dark drum]

So you'd need to have some data somewhere that would denote what line to go to based on the option picked. When the button is clicked, you'd then check the data.

A map of an int array could work. The key in the map would be the line, then the array in the map would have 2 (maybe more) entries for each line it would go to based on the selected option.

[short panther]

But the function will continue before the "completed" right ? How do I wait until it is loaded in the function ?

[surreal peak]

You can't with just one function. That's why it's also not available inside the function. If your whole code expects this to be instantly available then you can't use async stuff.

[last peak]

Create 2 functions 1 up to async load and when thats done you call the second funct

[crimson briar]

You need to disconnect the calling from the effect. Call the initial function/event. Then on load completed call some other function event that will handle the loaded data.

[trim matrix]

this will sound dumb but i wna word it as simple as possible so i understand. if i do this can i keep the way i have the text coming up on screen. bc rn its coded to work like zelda text boxes like typewriter style. i want to keep that.

[short panther]

Can I use a macro maybe ? Because i need to return the loaded asset in the return node of the initially called function

[last peak]

you need a tree

Whats happening right now is this
you click e - next text appears

Question appears
Now you have 2 options
path 1 - yes - spawn dialogue chain 1
path 2 - no - spawn dialogue chain 2

Now these chains might break down even further depending on what you want
path 2 - another questions appears
Path 2.1 - yes - 2.1 chain
path2.2 - no - 2.2 chain

[trim matrix]

yea thats what im trying to do

just saying i need a tree. isnt rly explaining what im doing tho😭

[last peak]

Try it i think it should take latent nodes?
But i think you cant call it from another bp

[last peak]

Because its too much to explain over text
This will take you hours, if youre fluid with bp's

[surreal peak]

The Macro will become latent. It's logically not possible to have an AsyncNode inside a Function.

A function is by definition required to return the same frame. A latent node is by definition not required to return the same frame.

You can't combine this. If you need it instantly, you gotta sync load.

[trim matrix]

why? i cant just use the check i already have that pops up buttons when it detects a question. then set the line from there?

[surreal peak]

If you can, why don't you do that?

[trim matrix]

bc its all working to that point

[short panther]

Oh, ok. Thanks for the explanation. That's much clearer now, I will try to do my logic differently

[trim matrix]

bc i have been trying to figure it out.. for days.

[last peak]

If you want to hardcode each single dialogue then sure ...

[trim matrix]

yea. i do. theres only a specific amount of options they can speak like i said

[surreal peak]

The problem here is that a proper dialogue setup, in which you don't run into such problem, needs to be designed from the start to support this.
The tree that is being mentioned is a way to structure all of this. Your widgets should never even really know what part of the dialog you are in. This is in theory part of an outside system that handles all of this and the data structure has to be properly chosen for this to scale well.
If you f*cked up your setup from the getgo and you are now trying to patch it together, then it won't work.
And explaining how to do this "properly" takes a shit load of time, that's why Blackhand doesn't want to.

[trim matrix]

which is why im trying to add it to what i have thats already working

[surreal peak]

Then do that.

[dark drum]

In terms of data structure, you'll need something like this. (as a simple example)

[surreal peak]

Even that is a pain to work with. There are free dialogue systems with custom graph editor available.

If I wouldn't have the knowhow on how to do this, then that's what I would start with fwiw.

[trim matrix]

i dont mind doing something like this, i dont rly wna restart this all or rely on a plugin.

[trim matrix]

im trying?

[trim matrix]

could u explain this a lil more. i slightly understand, but im a lil lost bc im new to using maps

[dark drum]

So when the player chooses an option, you would find the current line of dialogue in the map, (if there's one in the map) then from the array it returns, get the line index it should go to based on the option selected.

[dark drum]

I'll just leave this here in case you're interested.

https://youtu.be/oXwj2ahifgY?si=QqpAyuEifgBgtq8N&t=1805

[last peak]

Ok the most hacky garbage way you can do it
Add a enum, put all possible answers to questions in there
Before you select the next dialogue text you do a switch on that enum if enum == your answer continue from there

[trim matrix]

i looked at this. just didnt know how i can keep the typewriter style speech. plus i have it working up to detecting a question so i just wna kinda finish it instead of restart

[last peak]

You now have a hardcoded tree

[dark drum]

Its not too difficult to add the typewriter effect. It's been discussed a few times on my personal discord lol.

It'll be similar to how you already handle it where you parse out each character and add each one to the text box with a small delay.

[sullen violet]

Hello everyone, I’m relatively new to UE, I’m trying to implement switching items in the character’s hands, I have quite a few items and since I’m trying to do it this way it doesn’t look very good — to cobble together such a mess for a bunch of items. How is this implemented correctly? If it’s not difficult for you, at least give me a hint, please.

[dark drum]

Does anyone know if there's a cast for an array of objects?

[surreal peak]

No, in C++ you can do something rather ugly, but in Blueprints you gotta loop.

[dark drum]

I thought that might be the case. :/ Oh well.

[trim matrix]

i dont fully understand

[last peak]

Then there is no way how i can explain you anything even slightly more complexe

this is as simple as it gets

And im not saying this to beat down onto you

[trim matrix]

how does the switch on enum know what answer im selecting?

[last peak]

You either pull the text from your answer or you create a string variable manually and set it to the corresponding button

[last peak]

Which wont work if you have more than 1 question

[trim matrix]

but. how does it know what question was just spoken

theres two questions

[last peak]

Because there is display text in your answer

answer a - Yes i will do that
answer b - No i cant do that

[trim matrix]

but. theres two questions. and the responses from the npc arent always containing the words yes or no

[last peak]

It doesnt matter what they contain

[trim matrix]

then how does it know what question was asked. if theres multiple and they have their own answrs

[last peak]

You save whatever text you see in your ui as answer ...

[trim matrix]

what?

[last peak]

Your player can give 2 answers
Write down what these answers are for question 1

[trim matrix]

yea. the player has two options to answer the npc. but they are always a yes or no. no matter the question theyr always a yes or no answer. and the npc never says anything like “yes i can do this” or “ no i cant”

[last peak]

So what are the answers for question 1

[trim matrix]

the first question is, does the player want to start the mission (bring the npc their lost item)
if yes, tell them good luck and close the ui and then other logic inside the npc itself will run.

if no. the npc says something like aw well i hope you will help me soon, and then closes the ui letting the player interact again

[last peak]

no what are the answers that the player can give

write them in chat

[trim matrix]

theres nothing the player can give?

[last peak]

Lord almighty XD

[trim matrix]

theres a yes button. and a no button

[last peak]

Well there is the problem

[trim matrix]

what

[last peak]

Now you want a dynamic system

thats not hardcode

[trim matrix]

no. i have been saying this😭

nothing has changed

theres two options

only two

per question. yes or no

hows that dynamic😭

[last peak]

Alright then save last answer as int 1 for yes 0 for no

before you do the next dialogue

[trim matrix]

? again how does it know what question has been spoken to then provide the correct next line. so the answers for the 2nd question dont show up for the first and vice versa

[last peak]

• switch on int - if 1- continue from there

[trim matrix]

continue what from there😭 the increment speech or setting the next line of dialogue based on the button clicked

[last peak]

you see exactly this is the proble m

its impossible to explain this to you

You are lacking absolute basics

[trim matrix]

why. im sitting here trying to understand

[last peak]

This is like asking how do i solve this super hard equation before you can even count to 10

[trim matrix]

ok

idk what talking down to me is gonna do ab it

but. ok😭

[last peak]

This is the last time, i cant explain it more easy than this if you dont understand i cant help you.
You create a integer and you call it last question, by default its 0
If you press the yes button you set this integer to 1
If you press the no button you set this integer to 2

In your dialogue function, before you play the next dialogue you do a switch on int
If switch == 0 it means there was no question yet
If it is 1 - you answered the last question with yes that means you continue your code from there now
if switch 1 - next npc text == Npc Dialogue Box -"Set the text manually now" - set last question to 0 - play next dialogue

[trim matrix]

put the switch on int in place of the check that looks for the “?” or along with it

[chrome pumice]

yo guys, anyone here can help me with retargetting on the same skeleton?
im have diffrent sized characters in arm length etc, and i want all anims to look "normal" when i use them on another. my charactre bones have the same names but the ai retargetter has insane issues making this work. is there a way to use just the names? or can i maybe set up something once and reuse it. i would spend the time if i could keep reusing it

it used to be like this in ue5, just select the bone names and ez

now i got all of this clusterfck that i dont understand

[sullen violet]

Use the Auto-Rig Pro add-on for the rig and export through it as well, and everything will be fine.

[chrome pumice]

i already have multiple skeletal meshes in the game, cant i just retarget by name? without that weird stuff?

[sullen violet]

I had the same problem — Blender works very poorly with Unreal's skeleton. I solve it by using the add-on from the start.

[native stone]

anybody know how to attach a VR player pawn to an actor i.e. like driving a vehicle?

trying to make it so the player can enter a vehicle and whenever the car moves the player is still in the seat ofc but still VR so they can look/move around as per usual

I tried attaching the VR pawn to the car actor on startup and put the player start in the seat of the car but driving the car just leaves the player behind

[faint pasture]

Does attaching a br lawn do anything at all? Get it to do that first

[lost hemlock]

does anyone know how I can connect these?

I need to fix this error

I tried this tho

This doesn't work either

[deep plover]

Hey so im trying to play audio from the web browser widget, is there a way to do that or do i just have to entierly rewrite the web browser?

[lofty rapids]

is audio source and javascript .play() not working ?

you can also send a message to the game to play a sound

personally i would send a message and play the sound it's probably better

[deep plover]

wdym by "audio source"?
I cant seem to find anything audio related in the web browser widget component.
and idk about javascript.play()

[deep plover]

thats one way to do it, but i would rather have it work for sites that i dont have backend access to

[lofty rapids]

are you saying when you use the widget and goto like youtube its not playing sound ?

[deep plover]

yeah thats exactly whats happening, best part is that when on youtube specifically the videos only play when the audio is muted, when it gets unmuted the video stops and wont let me play it

i already tried force playing it using javascript but it still wouldnt let me somehow

[lofty rapids]

what version of unreal ?

5.5.4 seems to work fine

[deep plover]

Ue5.6.1

[lofty rapids]

is it just autplay ? or not playing at all ?

[deep plover]

The video is playing unless its unmuted, so when muted its playing just fine but when unmuted clicking the play button doesnt do anything

And the audio (when checking other websites) doesnt seem to play at all

[jovial bramble]

can someone explain why is my socket buging, i tried with all the animatiosn i'm using in my BPI, but it's always doing this

[lofty rapids]

Don't rotate the item first

Just put it on the socket

Zero transform

[jovial bramble]

didn't change a thing

[lofty rapids]

Show what you did

Did you just make a new transform ?

[jovial bramble]

i mean, no, i tried reseting everything, then i jsut gave some small transformation, bothing else

[lost hemlock]

Hi question, if I wanna cast to PCG_component.... what targe tdoes pcg_component inherit from,?

[brisk pine]

you're attaching to the wrong socket, you only used the socket for transform in the blueprint, remove the transform from spawned item and attach it to the flintlock_socket

[jovial bramble]

thanks, i will try this

[lost hemlock]

how to cast to this thing here?

[jovial bramble]

but what do you mean exactly by that, wich part

so what i need is to get the same socket from the attach

[thick flame]

This is a bit of a conceptual question, but I want some advice here on this idea for the main system in my game.

The Want
I need a system that allows myself and less competent game devs to be able to visualize a roadmap of objects (in this case, bubbles that the player can pop by clicking).
These bubbles will appear on screen, play an animation (growing, changing color) then be able to be clicked on.
This system also needs to allow for multiple object types, like enemies.
This is essentially a 2D scene, at least to the players perspective.

The Idea

1. The player moves at a constant speed along a singular axis (y, for example). this is like a playhead moving on a timeline.
2. Attached to the player is a Trigger box that lines up with the screen size.
3. Objects are placed stationary along the timeline axis at the x and z they should appear on screen at. They are hidden by default.
4. As an object reaches the trigger box, a few things happen. The object is unhidden, the object plays its animation, and the object gains the movement of the player.
5. The object is now on the 2D plane the player is viewing, and can then run any sorts of methods like movement afterwards.

Pro's:
-# that I can tell from what I know

• Ease of access
• Visually building the level out in the editor
• Possibly stacking another camera source, so that this system plays over the top of a background? not sure if thats needed though

Cons:
-# again, that I can tell from my knowledge

• Definitely more resource intensive than less visual alternatives
• Possibly overcomplicated? Im not sure

[modern cove]

I have a Camera Confines Box. Anyone know the difference between Get Box Extent vs Get Component Bounds --> Box Extent?

[warm mulch]

Hi everyone, I am new to Niagara Data channels and have a doubt related to it. I am having a Manager class that handles the movement of projectiles. In Tick, it loops through the active particles, does calculations, and check collisions all in C++. And at last, it calls Blueprint Event with an Array of Updated Positions of projectiles. In the Blueprint,I write to the Niagara Data channel by looping through the Array. I am using Niagara Mesh Emitter for rendering the Mesh, but it appears to be flickering. Is my approach faulty( which I feel it is)? How can it be improved?

[dark drum]

I believe getting it from the compound bounds means it should have scale applied.

I can't remember if rotation plays a roll as well.

[naive magnet]

Hello everyone, I'm completely stuck with Unreal's logic with VR.

I'm testing attaching the player to a moving platform so he can see around him. It's a VR experience where you just sit and watch.

But the thing is, I don't know how to attach the player to the platform. I tried yesterday different things but nothing accomplish what I'm trying to do.

For now I'm instanciated out of the scene and i'm not following the moving platform.

The blueprint is in the moving platform

Thank you

[sick sky]

you shouldnt run the attach function on tick

its a one time event

[dark drum]

So the bubbles would be (for the most part) stationary on the screen (from the players perspective)? Also are these bubbles supposed to be attached to something and do they represent something else in game?

From what you've described, it seems like it might be easier to just use a UI widget. The reason i say this is because people will play with different screen resolutions and any attempt to align that up with things in the world would be a pain.

[dark drum]

Casting is a type check with an updated return. A hit actor can never be a component which is why you get the yellow warning. (an actor can have components inside them)

Understanding casting is easier when you know more about class hierarchy and how inheritance works. I would recommend learning about it first to make your future endeavors easier.

However, if something is placed in the world it is an actor, things placed inside an actor are normally actor components. A static mesh actor is just an actor with a static mesh component inside for example. If you ever wanted to change the mesh, you would have to get a ref to the component inside it.

Hello, I'm trying to implement a behavior logic for an AI car in a race, making it follow a path by adapting braking and speed, avoiding collisions, and being able to overtake the player and others by changing lanes.

When I tested, the cars collide with each other and zigzag in a straight line. So I Want to Know how to fix the problem Cordially,

[crimson briar]

I don't think it requires "fixing" exactly. You just need to expand the AI to consider more things and add some variance. Right now it looks like it only wants to go in the most efficient way.
You could add avoidance - it would make the cars avoid other cars, somewhat. You could implement your own avoidace too, so when there is a car in front or next to it, it will do something else.
So it is more about making it feel better than fixing it.

I also see they drive at they always drive at the same speed. You could change their accelleration slightly to make them accelerate at different speed

And expansion on it would be implementing Driver profiles. SO you can define a few classes of drivers and implement behaviors based on that

For example, a Risky Driver wouldn't slow down before a turn. But a Careful Driver would. Dangerous Driver would bump into others, while another one would avoid it at all costs

The zigzaging probably comes down to the AI either changing the direcitons too fast or accelerating too fast. Lowering one or both of them should help with fixing this one issue

[fading sentinel]

For the logic of avoiding collisions and overtaking, here is what I did :

[thick flame]

How expensive is having so many trigger boxes? I always hesitate to put a bunch of them, especially on something moving. I don’t know if there’s any validity to that tho

[fading sentinel]

It mostly depends on the number in my opinion.

[fading sentinel]

Here's what I did regarding speed, braking, and steering:

Hi, I have a problem, the print appears in the Shipping Build version

[undone nest]

Hi there, I've got a quick question about seeds. When I pass the same initial seed into 'make random stream', it will return inconsistent results. What are some possible causes for this?

[glass blade]

Guys lets say i make a level (level blueprint) in unreal version 5.0, i also build the lightning data for it(bake lightning). Can i upgrade the level blueprint to a new unreal version? And also use the built lightning data for it?

[thin panther]

built lighting data, not sure, but the level blueprint is an absolute yes, it's just an actor

[glass blade]

Hmm technically i wouldnt even want to use the built lightning data in the editor, just package out the level /project with the old building lightning data

[warm mulch]

Bump :/

[maiden wadi]

The short answer is that if you call that with the same seed, you will always get the same identical stream.

Most people get tripped up on this due to Blueprint's pure functionality calls though because of the way BP's execute their pure nodes.

So, hard to really answer without seeing your BP logic.

[undone escarp]

Is Foo only called once here despite Bar using 4 values from it?
I tested it so it seems like that's the case but I'm asking in case I'm missing something 😁 So I guess a pure node only gets called once per execution node, no matter how many pins are used?

[next hollow]

Yeah, I believe every node its used in is a new execution.
I also used to think it was every pin, cuz I'd use 1 output functions, such as random float
So, if you had a + going into one of them, it'd be twice?

[undone escarp]

only got called once for this as well

[next hollow]

Oh, interesting. 😛

Well.
Good to know I guess.

I usually cache pure outputs anyway, if there any dynamic output.

[undone escarp]

and here Foo gets called twice

yea I'm always vary of pure outputs 😄

[rose anvil]

I would have thought it'd be called 5 times

pure nodes are weird man

[next hollow]

My brain only somewhat recently realized how bad/ crazy the pure parse functions are, when put into a for each loop. 😛
500 array elements, each 1 loop needs to re-parse the 500 elements.
Casual server timeout. 😛

So, 99% of dynamic pure node outputs, I cache, just in case.

[undone escarp]

haha pure node + loop is so sketchy

[faint pasture]

You need to unify all your considerations into a single desired path

You got the default path
You modify it for overtaking or dodging considerations
You have code to output the vehicle control inputs based on state and path

[crimson briar]

In most cases, pure nodes are called once per execution pin, even if you use the same output for multiple inputs. Loops or some macros being the exception of course.

[fading sentinel]

You need to unify all your

[shut blaze]

how do I set a "Text" in a widget without using binding?

ping pls

[lunar sleet]

Set text node

[shut blaze]

I can't find it

[lunar sleet]

See 3rd pin from Cedric to understand pure node functionality

[shut blaze]

I don't mean the variable

[lunar sleet]

Get a ref to the widget, drag from it

[lunar sleet]

Drag the clicks in your graph

[shut blaze]

..... how exactly?

I give up

[lunar sleet]

Bit early days

In your graph tab at the top right you can put code (nodes) in

While in there you can drag a widget element and get the relevant function

[shut blaze]

yeah, I don't know about that, text does not show up in the variables tab

I'm gonna use bind, unreal is weird

[last peak]

Really, that fast? Hmnn then gamedev will drive you insane very fast 🙂

Dont use binds they run on tick

[shut blaze]

fast? was like 40 minutes trying to figure that out

[last peak]

disgusting

[shut blaze]

I know I know

[last peak]

is the text a variable ?

[shut blaze]

small game, but just wanted to know for the future
no

[lunar sleet]

check the box that says isVariable 🙂

then you can use it

[last peak]

in your designer when you click your text on the top right (i think) is a checkbox that says Is Variable

[shut blaze]

bruh

[last peak]

XD

[shut blaze]

I was searching for that

cant count how many times i slammed my head against the wall just to find out after hours it was a goddamn checkbox or just a bool that wasnt properly set

that's gamedev in a nutshell. hours spent on a missing checkbox

[crimson pollen]

Is there a way to dynamically get your table name? An example say I created a function called AFUNCTION. If I get a reference of self its obviously going to be the blueprint name but I would also like to be able to get the function or whatever name im trying to get a reference of. I am trying to create more robust debugging this way

im using blueprints BTW

[next hollow]

Yeah, I know BP can't get that info.
and, I think C++ even has to do some weird stuff for function names and such?

[crimson pollen]

That sucks. I'm trying to make a structured log for the entire code base and it would be so much better if I was able to get the function names into the log itself

That would simplify my bug tracking.

[maiden wadi]

Yeah, that's fun to do even in C++. :/ Not aware of any functions by default that get their current callstack or function name though.

[fiery glen]

that is a setting isn't it? bp.BlamePrintString

a cvar to be specific

UKismetSystemLibrary::PrintString to see how it works

[crimson pollen]

IDK what you mean. How does that pull the function name

[next hollow]

I believe there is a blameprintstring 1 command you can run, to make print string output function name and shit.
Built in

Yeah

[crimson pollen]

ok yeah it seems that its not exposed to blueprints

[next hollow]

No

[crimson pollen]

Im guessing that would need to get coded in

[next hollow]

Its a command var.
So, like run on startup

Happens for every print string

So, kind of what you want, but maybe a bit too much.
But, better then nothing at all

[crimson pollen]

hmm

no its not exactly what im looking for it seems to do the same thing that printing self would do

im talking about printing the actual function name itself or the macroname. I could use a log and manually put it in but its hard to manage 4 other people to do that

[next hollow]

Gives you self, and previous function name.

[crimson pollen]

only thing I got was this LogBlueprintUserMessages: [Experiments_C_17] Blueprint Object: /Game/EditorUtilities/Experiments my function name is Process HTTP Request

[next hollow]

Should be an entry right under it.

[crimson pollen]

nope

[next hollow]

I get this:

Blueprint Function: ExecuteUbergraph_Buff_Armor_Type_Manager
Server: Added: Item: PrimalItem_WeaponSpear_Explosive_C_10 --- Equipped: false

[crimson pollen]

oh thats weird

I disabled it and re-enabled it and it worked

yeah I suppose that's good I need to figure out how to copy that data to something I can pull from like a string. Thanks that at least gets me a bit farther along

[junior crane]

hey simple question:
how do I open a blueprint in a minimized view again? The BP doesn't have any graphs inside and only want to edit the defaults. so how do I make that now when I reopen it is back in that minimal view?
Thanks!

[next hollow]

Re-open the whole editor.
It’s checked on first file open, the cached.a

[junior crane]

oh wow ok. I thought there is some trick to make it happen

[chilly junco]

im kinda new to unreal and I wanna know how hard would it be to make a minecraft block placing system

[surreal peak]

In a naive way, not too hard. In a performant way, probably nothing for a beginner.

[chilly junco]

Im intrested in learning

how would you go about doing this

[spark steppe]

it's pretty much just a 3D array, isn't it?

[surreal peak]

Done properly it's way too much to explain here. Check if you can find a tutorial. You most likely want to create the blocks as part of a Runtime Generated Mesh, as Minecraft itself doesn't actually have any "blocks", it just renders the visible outside of it. If you were to phase through a block, you'd see "nothing".

[surreal peak]

The performance is a problem though. You can't start placing one Actor per Block :D

[spark steppe]

yes, rendering and storage are another topic

iirc there are talks about how they handled storage after they updated the chunk format

[surreal peak]

I doubt this is something for a beginner tbh

[spark steppe]

yea

[chilly junco]

what would you recommend for a beginner

[surreal peak]

The most basic games you can think of, such as pong or so.

Your main goal should be learning the Engine, not making a Game.

[chilly junco]

yeah i kinda thought that

[chilly junco]

And how do i do that

[surreal peak]

tbh, probably by watching/reading tons of different tutorials about simple games or parts of the engine.
You should start by learning what all the different available classes are for for example.
If you have never programmed much with OOP languages before, then you should also learn that part, as Blueprints are basically C++ in that regard.

https://dev.epicgames.com/community/unreal-engine/learning?types=learning_path

Official Tutorials/Documentation is probably worth starting with. There are a ton of what Epic calls Learning Paths.

https://dev.epicgames.com/community/learning/paths/7a/welcome-to-unreal-engine

https://dev.epicgames.com/community/learning/paths/0w/unreal-engine-beginplay

This is probably a good thing to fully read 5 times.

TY

[next hollow]

Lol
I’ve never seen these before.
I thought the begin play section.
Was an entire video of how begin play worked internally or something. 😛

[surreal peak]

I would be amazed if you can make an entire video about a function call.

[next hollow]

From the link generated pic by discord.
I thought it was a fully break down of begin play code execution.

Now I see the pic is the learning chunks of other stuff. 😛

[surreal peak]

I mean, I guess BeginPlay could be worth a few words, but yeah.

[next hollow]

I saw someone do something “similar”, with a 40 minute video.
Not 1 function, more like 8
But, all 8 functions had perfectly logical and understandable names, and any inputs/ outputs were named well.

Gorka tutorials ? 😂

The king of event tick

"Today im gonna show you how you can create a inventory"

Proceeds to create a array of strings and displays them in a widget and calls that inventory LMFAO

[crimson briar]

In the text line above the defaults you should be able to click o the next "open full view" or something like that.

[mild jacinth]

there doesnt seem to be a gas-related channel so imma just ask here, does anyone know how gas gameplay effect tags work in 5.5.4? i cant seem to be able to set tags either in gameplayability nor the gameplayeffect. its just the cooldown effect class bp that can be assigned in the gameplayability

[steady night]

hey guys im having an issue with my save/load where everything works except when its saving duplicates of same item, (it dosent save or load the duplciates it reacts as if its only 1) any ideas ?

im adding the items a Unique in the array

[crimson briar]

#gameplay-ability-system

[crimson briar]

Well you are using addunique. If your items have their own classes, like BP_Bow, two bows will have the same class. So you should use Add, not AddUnique in this case

[steady night]

oh your right, ill try that

[steady night]

That was the issue, easy misstake 😉

[supple charm]

Why wont this work? works for basically any other widget i have in there

Wont work for LootableWindow

[crimson briar]

What are the Gets connected to on the left?
Also try unchecking top level only

[supple charm]

is valid worked better, thanks for the help tho

[last peak]

Yoo i wasnt even aware that this nodes existed "get all widgets of class"

interesting

[frigid quartz]

Hey guys, do anyone know, how much RAM (very approximately) a loaded blueprint class asset would take in shipping game build, if it's derived from UObject, has a single tiny function and no fields?
I've tried asking this question to Chat GPT multiple times, but its answers varied from 500Bytes to 50KB depending on slight changes in question wording:)

[stone field]

I would wager we are talking kilobytes, not megabytes, but have no proof

[frigid quartz]

Oh sorry, that was a typo, 50KB, not MB

[stone field]

phew : )

Basically if you open the .uasset file in a text editor, you could make a very rough estimate based on how many A4s of text there are : 1 A4 = 1kb
( this is assuming the actor isn't loading up anything else )

[frigid quartz]

What A4 signifies?

[cunning vapor]

QuickQuestion!

I'm about to add audio to my game; and was thinking; what would be best? Has anyone used option B before? or is it a tad too much ?

A:
Have the "play sound" on every blueprint/action that requires it

B:
Have a "Common function library" for audio and just use "play falling" "play hit" events

[stone field]

A4 page of text = 1 kb of memory ( this is a very rough ballpark thing from ages ago )

[frigid quartz]

Strange, can't find any A4 in my blueprint .uasset file. Will this method also count editor only data (graph, nodes, pins, etc)?

[dark drum]

Right click -> Size Map, there's an option to view disc space and ram.

[stone field]

that's the correct answer! sidenote, a bp opened in text editor starts like this: ( and a random one I popped open was about 30 pages of binary blob )
Áƒ*žøÿÿÿ`  õ Ÿ‹øüJuˆÙ|¦)½:81 Ýuå)'F£àvҝêÜ,# <Á^7ûHäð„ µ~q*& R]ÚYHI2xYx¸‹é¸p ·L[øJc$p¿[€ÝÐõÍ †`„Od¬ÞÓªÖÇê ª Õ}i«AOæìQJª(¶·¾w "ÕTœ¾O&¨F!”Ђ´a, ä2Ø° O‰·~Ϭ¢Jý6

[dark drum]

It'll look like this. The answer is that the size can vary wildly depending on whats in the BP.

[stone field]

Totally forgot about that feature : )

[dark drum]

Either option is valid, just depends on your game. I personally would start with A but if i find i'm repeating myself a lot, i'd probally look at creating a FuncLib.

[cunning vapor]

Yeah thought it may repeat a lot due to it being a medium-large game so maybe a func lib would be good; thanks again P!

[frigid quartz]

Yeah, I know about this option, but I'm not sure:

1. Does it shows a size of class asset itself (not instances of that class)?
2. Does it counts editor only data?

[dark drum]

Its based on the class default object (CDO) for the given class.

As for editor only stuff in a BP only project I don't know. As far as I know this is only something you could handle in C++ anyway.

[fading sentinel]

To create these driver profiles, do I rely on a data asset, a data table or a game instance to implement these different behaviors?

[crimson briar]

I mean, it was just an idea how you can make the race more varied so they don't follow eachother in a straight line. I don't have a concrete implementation in mind.
Personally I would try to make it like a config in a data asset, then each AI draws one of the assets for itself and the AI logic does stuff depending on the data it was given. BT could pull from the data asset as well

can someone tell me why it's making an infinite loop

[crimson briar]

Your condition is "While Array Length >= 1"
And you never change the length of the array. Swap makes two elements swap places, same length.

What is the "LastIndex"?

You decrement it but I don't see what it is set to. Maybe you should set it to array Length before the while loop and use this Index >= 1 for the condition instead

(I'm guessing though)

[jovial bramble]

it's the last index of the array

should i set it with the array it self (the length)

[crimson briar]

Well yes, how else will it have the last index of the array

[jovial bramble]

you're making a point
so i have to set last index with the length of the array

[crimson briar]

Yes. And use this last index in the comparison that is connected to the While Condition.

[jovial bramble]

i think i understand now, thanks a lot

[jovial bramble]

i tried again, sadly i'm still havin an infinit loop

[faint pasture]

What are you actually trying to do here?

[jovial bramble]

it's jsut some practice for learning arrays

[faint pasture]

also length and last index are not the same thign

an array of length 5 has a last index of 4

[thick flame]

You are setting the last index and then evaluating the last index with nothing in between to affect it. This means that last index will always be equal to the length of the array.

And what @faint pasture said- you need to subtract 1 from the length for your last index. Indexes start at 0 and count up.

[faint pasture]

also no matter what this will always run forever. Your while condition is while A > B, and you decrement B
A will never not be > B

[crimson briar]

You were supposed to use the LastIndex in the comparison >= 0. If you still use the length, it will still be infinite, since length of the array doesn't change in this function.
When you have a while loop, each time it goes back to it, it checks if the condition is still true. If yes, it proceedes.
Let's say your array has 5 elements.
You set the last index to 5 (I'm skipping the -1 issue for now).
Then you compare the array length against it, so 5 >= 5
Enter the loop, last index decreases by 1, so 5 >= 4
next, 5 >= 3
Next 5 >= 2
So you see the problem?

If you change it to compare the LastIndex variable to >= 0
Enter the loop, 5 >= 0
Then 4 >= 0 (since you decremented it in the previous step of the loop)
etc etc and it will break when the LastIndex reaches -1

And yes, I didn't talk about the indexes not being entirely correct, the guys above are right. I just usually try to help with fixing the issues one at a time when someone is new.

[jovial bramble]

i'm gonna try to understand all of this

[thick flame]

This would work, except that they’re setting last index to the length of the array every time, before the first branch. It needs to be done once outside of the loop, otherwise it will be infinite.

[crimson briar]

You sure about that?

[thick flame]

I’m struggling to see everything that’s happening, bc of the size and the layout, but I think so.

[jovial bramble]

https://blueprintue.com/blueprint/p11002mx/

if you guys want, i can share the BP

[thick flame]

Ok I was totally missing that the middle one was the while loop

[crimson briar]

Now the comparison is better but you removed setting the last index, so it will always have default value, no matter the length of the array. Have you done any programming/blueprint courses or smth?

[jovial bramble]

so i still need to set last index with the length ?

[crimson briar]

A variable is a container for a value. This one is int, which means a number. If you don't tell the engine what to put there (in this example, the length of the array it is supposed to relate to), it will be always empty - meaning, 0 in this case.

[jovial bramble]

i see

[fiery flower]

Why am i getting these errors?
Blueprint Runtime Error: "Accessed None trying to read property CallFunc_SlotAsUniformGridSlot_ReturnValue". Node: Add Child to Uniform Grid Graph: AddItem Function: Add Item

[lost eagle]

hey guys! quick q
i am experiencing camera transition lags using the "Set View Target with Blend" node
it works completely fine until i add a blend func that isnt VTBlend Linear

anyone else experienced this?

[sand shore]

Carefully consider whether you're fully protecting "Add Child To Uniform Grid Graph". Trace all the white wires.

[fiery flower]

I think this issue occurs when I add the first element, because at that moment there are no elements yet, and I'm trying to access an element in the grid panel

Yes, that was the problem. It's been fixed

[lofty rapids]

your not altering the array and checking the length which never changes?

i see you swap

but this doesn't change the size

[glossy leaf]

Hey, I have a question about rotations. I have a box that the player picks up and carries, and I want the face closest to the player when the player picks up the box to always rotate to face the player. How would I achieve this?

[onyx gull]

are pawns strictly necessary? Are they still advisable even when you don't need the functionality of moving an actor through input?

The game I'm working on largely involves sorting through and moving around objects from a first person perspective, similar input to the desk view in Papers Please. I'm still generally trying to get a solid handle on the Pawn-Controller paradigm but as far as I can tell a pawn shouldn't even be necessary.

Granted, trying to initialize my game with the gamemode Default Pawn class set to "None" seems to break the camera and such, and I'm not sure whether the solution is to just initialize the camera myself or just stick with the pawn and avoid touching most of its functionality

[crimson briar]

Hm, or maybe you don't need the pawn actually. I guess I'll test it because now I'm curious

[lunar sleet]

Pawn comes with a bunch of prebuilt functionality that you don’t have to then do yourself. If you don’t have a valid reason not to use it, no need to go reinventing the wheel

[crimson briar]

Well, apparently you can have no Pawn. You just need to set the view target for the player controller to some camera

Like a camera actor placed in the level

Inputs you handle through a controller

[onyx gull]

good to know, thank you both.

[forest tangle]

Hey guys, got a problem with a blueprint. Asked AI about this a lot but it's just trying to convice me of something that isn't true. So, I have a problem with delays. Seemingly, delays ignore new executions when there's already one in progress. Is there any way to make some kind of async delays or would I really need to create a new actor that I need to spawn multiple times just to run some delays simultaniously?

Would have to be BP only, UE 4.26 compatible and without any libraries too btw

You see, I just have an event dispatcher where I want to attach a delay to the event. This seems to mess up a lot since the way delays behave would simply get new events ignored when there's already one in progress

[rose anvil]

", I just have an event dispatcher where I want to attach a delay to the event"
So you have a custom class to dispatch events, when outside actors call this global unique event dispatcher, e.g. EventDispatcher.CallSomeEvent
and inside the definition of CallSomeEvent you do Delay(10 seconds) -> do the actual event call ?

and you would want the delays to properly queue instead of overwrite one another ?

I'm not aware of any easy way to do that in BP but it's super simple in cpp:

DECLARE_DYNAMIC_DELEGATE(FMyEventDelegate);

UCLASS(Abstract, Blueprintable)
class UMyEventDispatcher : public IdontKnowWhatsTheParentOfTheEventDispatcher
{
    GENERATED_BODY()

public:
     UFUNCTION(BlueprintCallable, Category = "Event dispatch")
     void TriggerDelayedEvent(FMyEventDelegate EventDelegate, float Delay);
}

void UMyEventDispatcher::TriggerDelayedEvent(FMyEventDelegate EventDelegate, const float Delay)
{
    FTimerHandle DummyHandle; // If you don't need to keep it
     GetWorld()->GetTimerManager().SetTimer(DummyHandle, FTimerDelegate::CreateLambda([&EventDelegate]()
    {
        EventDelegate.Broadcast();
    }), Delay, false);
}

[forest tangle]

I don't think this really matters where the delay is. I just want to have multiple delays that don't interefeer with each other

[rose anvil]

smtg like this should do the trick

[forest tangle]

As I said, I can't use C++

[rose anvil]

why not ?

[forest tangle]

I'm making a mod for a game where modding is restricted to bp only specifcally

But I think I'll just make a separate actor for handling multiple delays

[rose anvil]

Well then I'm sorry, I don't know how to do it in bp only :/

you can make components instead of actors though

it's lighter and the components can self destroy when they're done

[forest tangle]

Not really ideal for what I'm doing tbh. Thought about it already

Well, maybe I can give it a try

[rose anvil]

I don't have anything better in mind 🤷‍♂️

good luck!

[forest tangle]

Actually got it to work with a component lmao

[rose anvil]

nice !

What is this supposed to mean ? Seemingly, delays ignore new executions when there's already one in progress
