blueprint

[copper steppe]

If it isn't an actor, what is it then? a component or?

[foggy otter]

a barebones object

[copper steppe]

Can you even add a bare object to the world?

[foggy otter]

this

you can create them with this

[copper steppe]

I don't think what you are trying to do is possible? How exactly are you doing it?

I would assume, that the object would have to be at least an actor 🤔

[foggy otter]

why would it need to be an actor? i dont need it to exist in the world or have any interaction with the world i just need it to hold a variable that i can retrieve later. i figured making a whole actor for that is overkill and a barebones object will be more efficient

[copper steppe]

What does it say when you print out a reference to the created object? From my understanding of it, the "Object" reference you would be getting, is a nullptr/empty?

[foggy otter]

nope, it prints out the name and number of the object properly

the reference is there as it should

[desert juniper]

is this on a multiplayer project?

[foggy otter]

yeah but there is no multiplier code with this object. its just run fully locally

so im not gonna be replicating it or variables from it or sending ot over an rpc

[desert juniper]

what do you mean by run fully locally?

[foggy otter]

that each client will use it on their own, in their own local actor. they will spawn it themselves, do things with it themselves and destroy it themselves.

no replication with it, basically

[desert juniper]

ah, and are you sure the client owns it?

[quasi vault]

Is there an animation chat? I have a problem that is half blueprint half animation

[foggy otter]

yes. also im testing this on the server right now so ownership should not be a problem.

[copper steppe]

#animation

[desert juniper]

That's odd. so the player is creating an object, setting itself as the owner, and storing a reference to it. later moidying that object. at that point the changes aren't saved
right?

[foggy otter]

wait, i need to explicitly set owner? its not inherited from the actor which creates it?

[desert juniper]

I believe that's correct. let me check the source code

[foggy otter]

im not sure a barebones object even has an owner that you can set or check

or maybe its just not in the blueprints

[desert juniper]

GetOuter would be it

it returns the UObject that owns that object

[foggy otter]

ok so i printed that out and it says /Engine/Transient

so im guessing that means the owner is not set?

how do i set it in bp?

[desert juniper]

Okay in CPP you have to explicitly state the outer
auto NewItem = NewObject<UItem>(GetOwner(), Item->GetClass());
are you able to set it in BP? is there a SetOuter node?

[foggy otter]

nope

[desert juniper]

wait.

why aren't you constructing it with the construct node?

that allows you to set the outer when creating it

[foggy otter]

wait shit you're right

[desert juniper]

(along with instigator)

[foggy otter]

yeah

i totally thought they were the same thing

didnt know there were two methods for creating base objects

i just used the first one i saw cause i assumed its the only one

thank you!

[desert juniper]

I don't actually see the Create Object node you created, but that doesn't look like right. it shouldn't be a pure node, as there are side effects.

is that one you created? in a bpfl or something?

[foggy otter]

i dont think so

[desert juniper]

hmm odd. 🤷‍♂️
oh well. at least we figured out your issue 🙂

[foggy otter]

oooh its from extended standard library

xd

thats why

[desert juniper]

side note, have you looked into subsystems?

might be easier since it sounds like you're creating a singleton anyways

[foggy otter]

huh, i havent

[desert juniper]

oops. my b. looks like they're not yet exposed to BP

[foggy otter]

i mean, i just want a thing that holds a variable and that i can nest multiples of it in each other as children in a tree structure. so i figured a base object would be most efficient for that

[desert juniper]

sure. that would work out just fine.

[foggy otter]

okay, thank you so much for the help! i think this should fix it

[desert juniper]

if you ever want to replicate that object take a look here
https://jambax.co.uk/replicating-uobjects/
also a cpp only thing. my bad again

[foggy otter]

cool, thank you

[copper steppe]

I've been trying with this for a while now, but I have not been able to make it do it correctly so -

I've got an actor with a mesh, with two sockets at X distance from each other

When a spline with a spline mesh component overlaps the actor mesh, I want to figure out, which of the two sockets are closest to a specific spline point

I tried using a simple multi sphere trace but it ended up getting 4 different mesh components (Even though there were only two within the trace?)

I also tried calculating the distance from each socket, to a specific spline point, but my math looks to have been wrong/inconsistent in the correct answer

TLDR
How can I consistently find the closest mesh socket, to a specific spline point on another actor?

[desert juniper]

do you have the (vector) location of the points you want to check?

[copper steppe]

I have the location of the spline point & I also have the location of each socket, yes

[desert juniper]

can you loop through all the socket points, find the distance, and save the closes point on each loop?

once that loop is finished, you're left with the closes point

there we go

[copper steppe]

That was my first thought, but the sockets have the same X & Z coordinate, and if the spline point, is etc. overlapping socket1 with Y500 and socket2 with Y400, then I would want socket1, since that was the first overlap

If that was understandable? I dunno if i made sence haha

[desert juniper]

not really. because that's no longer the closest point

so if they are overlapping, then you want to instead use the first point?

isn't that just this?

[tight schooner]

Distance(socket #1 world location, spline point world location) > Distance(socket #2 world location, spline point world location) = boolean

[copper steppe]

There are cases where we might overlap socket 1 & 2, if that is the case, we want the first socket overlapped, from the direction the spline is going (there of course might be 32 spline points, before the overlap)

[tight schooner]

Uhh

So you can get closest point along spline to world location

There's a node like that

And you figure out which one is closest to the end of the spline you're prioritizing?

[copper steppe]

The one closest to beginning of the of the spline

[tight schooner]

Basically the function has to start by answering the question:
Is there a double overlap? If yes, then...

There should be nodes to determine the closest "time along spline" or "distance along spline"

And you figure out which socket is closest to time (or distance) 0 along spline

[copper steppe]

I suppose?

[tight schooner]

@copper steppe Find Input Key Closest to World Location

get the closest input key for sockets #1 & #2 and the lower number is the winner

[feral nexus]

is there a node for lets say. if number is between 3 and 6 then true otherwise false?

[tight schooner]

@copper steppe

[tight schooner]

dunno but you can always make a Math Expression node

oh actually there is a node

InRange (Integer)

lul

[feral nexus]

ooh thank u that is exactly what i needed thanks

[copper steppe]

It works, I'll have to double check my previous work though, cause it seems I might have switched around, the closest and the furthest away socket namings

Thank you though, now I can finally go to sleep!

[trim matrix]

hello

i'm having a prob with a BP

[tight schooner]

ask away... If anyone knows the answer they'll chime in

[trim matrix]

whats wrong ?

[tight schooner]

try #animation if you don't get an answer here. #blueprint is more about gameplay logic

[trim matrix]

CHRIST, I did it. FINALLY

the solution was simple. but I blame myself totally. I don't sleep much these days and are prone to small oversights. I work over night, and don't sleep when I get home. (I've been awake from 1145 PM CST all the way to now, and that was the same case as yesterday)

[tight schooner]

yeah fatigue does that

[trim matrix]

Thanks for working with me though I really appreciate your patience. Moving the remove icon function into the inventory widget instead of getting a reference from it inside the icon widget itself fixed it perfectly.

[junior hedge]

I tried working on a new project at 3am and I couldn't even add a widget to viewport LOL

and I also called an overlap event without adding a collision and got confused

[trim matrix]

it be like that

Here's it in practice, should be way more interesting for mobility once I've actually given each object it's unique ability other than kick

[sage magnet]

Hey hey people,
I use child actor component to spawn actor inside an actor before begin play happens. When I test my stuff, my part actor moves, but the actor that was spawned by child actor component stays behind. How do I force it to follow the parent?

I am just used to adding objects with functionality in Unity without any hassle and here it's very difficult.

[broken wadi]

Use one of the Attach nodes. (Attach Actor to Actor) or (Attach Actor to Component) depending on your needs.

[sage magnet]

on parent or spawned child actor?

[broken wadi]

If the parent has a skeletal mesh, you can make things easier by passing in a specific socket.

[sage magnet]

Do I have to use cast?

[broken wadi]

Depends on your game, but it sounds like you want to attach the new spawned thing to the existing thing.

[sage magnet]

yes

I was hoping child actor component would do that automatically

[broken wadi]

Then just make sure "Weld simulated bodies" is enabled and it will follow the thing its attached to.

or actually, maybe that only depends if physics is involved... hmm

For my CTF game, I used to have it so whenever a character pickups a flag it was being destroyed, then spawned and attached to the character. But I found this was slow and causing some noticeable hitching. So instead I did a trick where the character is actually always carrying an invisible flag and its simply made visible whenever they go to pick up one instead.

You may want to do something like that because spawning actors (with lots of hard references) can be expensive and slow if it happens frequently.

[sage magnet]

Hm, I have a belt with items attached on it.
I can't figure out how to force those items to follow the belt

[broken wadi]

The belt is on a character ya?

[sage magnet]

Yes, so it's kinda child actors of a child actor 😅

Player is parent

[broken wadi]

Is the belt part of the skeletal mesh?

[sage magnet]

Nope, it's a VR capsule

[broken wadi]

Okay then just attach without using a socket and adjust the relative location after

[sage magnet]

I'll try that, thanks

I wish UE5 could support flexibility of GameObjects from Unity

[faint pasture]

Why not just attach the flag to the character

[broken wadi]

Better network performance to just do a bitwise operation then do the visual effect client side.

Instead of attaching the flag to the character

[faint pasture]

I mean it happens like once per minute, it's literally nothing

[broken wadi]

I have many different flags in my game and they have stuff happening on tick. Rotate to face player for example. So I decided to hide them and disable tick then toggle the visibility of the fake flag directly on the character.

Also when I was testing with a bit of packet loss the RPC to do the attach wasn't working 100% of the time.

So now I replicate an enum because of the different flag types.

[winged sentinel]

hi everyone, im even getting accessed none with an is Valid check. Why? shouldnt it prevent execution if theres nothing valid?

[fiery glen]

FP Primary weapon is not valid checked before you access a member variable on it

[winged sentinel]

im having trouble understanding, im doing an is valid on it, but the is valid itself is saying accessed none

in the branch

[fiery glen]

to check the root component you need to get a FP Primary weapon

[winged sentinel]

nvm i missed pins

lol i forget to connect them

embarasing

[fiery glen]

oh, I see it now

I missed it too

don't worry, I do stuff like that all the time

[winged sentinel]

thanks for the help it all works now!

[modest terrace]

how do we set a jump height in for the jump node ?

[gentle urchin]

In the settings

[modest terrace]

got it, thanks

[gentle urchin]

If this is what you want then just do it in the settings

[junior hedge]

Just curious what would happen if it's flag is too far down below? How would you change that?

[bold barn]

what is the return value of the set timer by event function? in this case, does it change every 1.5 seconds?

im watching a tutorial btw

[frigid hill]

Hey there, anyone know of a way to execute (launch) external .exe softwares from disk, in runtime using blueprint from Unreal?

I want to make a game launcher

[tight schooner]

It's a timer handle. It lets you get data from and manipulate the timer after you set it.

That's what makes it more powerful than a delay node

[mortal wharf]

Why can I change the inputs of some custom events, but not others?

[limber parcel]

how to get the scale of something as a float?

[jaunty stirrup]

Can someone tell me how works this node? I want to know if i can get the water surface location giving it close location

[limber parcel]

why not just do a raytrace?

[jaunty stirrup]

Good idea thx

[tight schooner]

One seems to be an event created for a specific dispatcher (follow the red delegate line), so the inputs are defined by the dispatcher the event is bound to.

[worthy tendon]

how to get players in blueprint and know which player is for which client?

[tight schooner]

Get Player Controller, Get Player Pawn, Get Player Character etc.

[limber parcel]

GetPlayerCharacter

[mortal wharf]

Thanks!

[tight schooner]

guess you could do Get Actor Bounds, take the box extent output, and VectorLength * 2

and that'll be the diagonal length I think

[limber parcel]

no i need like the scaling ammount

[tight schooner]

maybe Get Actor Scale 3D and pick your favorite axis

or average them

[limber parcel]

i tried that but for some reason it always returns 0 lol

[tight schooner]

huh.

[limber parcel]

nvm i guess im just too tired for this

[bold barn]

what data is it returning in specific?

[tight schooner]

The data type is "timer handle structure". Doesn't seem to be a struct that you can split/break though. It's kinda like an object reference in the sense that you can call functions on it

Can't say much more about it personally. You'd probably have to dig into the source code or something.

But you can treat it like an object ref; you can save it to a variable to manipulate the timer elsewhere e.g.

[bold barn]

if the return your getting is a reference to the function wouldnt that make the return value a lambda?

@tight schooner

[tight schooner]

sorry, dunno

dig into the source or ask #cpp if you want specific information about it

[bold barn]

ok ty

[tight schooner]

I only know enough about timers to use them in BP

[bold barn]

when should i use functions vs macros vs events

macros just seem like functions but you can use time

[tight schooner]

@bold barn Macros are nearly equivalent to copy-pasting nodes on the graph. They're for ease of BP'ing within a class; signal flow is a good use for macros because they don't have limits on exec pins. It's like a collapsed graph that you can duplicate and update in one place.

The problem with using macros for everything is they can't be called outside of the class, and they can't be inherited or extended or overridden in child classes. And ofc you can't set timers on them. Functions have more rules governing what they can do, but if you can work within their limits, then they have more power

esp. when it comes to logic that directly or indirectly involve multiple classes

You can take from UE itself -- the "standard macros" included with the engine are signal-flow type things

Loop, Gate, Do N, FlipFlop, etc.

[bold barn]

you can have timers on macros

[tight schooner]

you can't "call" a macro so I don't think you can connect a delegate to it (the red pin on the node) like you can with a custom event

I mean, you can, if you give it that input, but internally there's nothing to execute per se

cuz you can't wrap an event in a macro

[bold barn]

so macros are just for ease of use and organizing

does it improve performance in anyway?

[tight schooner]

pretty much. I tend to use it for simple stuff, like if I'm checking the state of something and branching execution several places in a class, I turn that into a macro for convenience

nah, it doesn't do anything for perf. Placing a macro node onto the graph is equivalent to copy-pasting the contents of the macro

when compiled

[deep geyser]

Couldn't you use Vector3 Length node?

[tight schooner]

length will give you the diagonal instead of the transform scale

it sounded like he wanted the transform but somehow represented as a float

idk why it's giving him "0" though

[finite flax]

Why my PNG file not being transparent?

[tight schooner]

Is it a PNG with an alpha channel or is it just a black and white image? Try connecting the "R" pin to the opacity and leave base color disconnected. Anyway, future material node graph questions should go to #graphics

Probably want to use masked opacity too

[finite flax]

its png with alpha yes

oh sorry about that, thought there was a material #channel

thank you

[queen sequoia]

hey, I just have a small question real quick, How do I stop a random int variable from getting the same integer more thane once in a row for example right now its like (1 1 1 3 2 4 4 4 ) when in reality I need it to be (1 4 2 3 4 1 3)

[valid grove]

Is it not possible to hide actors in a streamed level from another or persistent level ? In my test, even though the HiddenInGame bool is enabled, the actors are still not hidden.

[deep geyser]

Does anyone know how to dynamically bind a child actor component with physics constraint component through blueprints?
I casted to the child actor component's actor class and trying to bind the root static mesh component, but I did not work.
Here is the BP function that I call on construction
https://dev.epicgames.com/community/snippets/PVA/unreal-engine-bind-child-components-with-physics-constraint

[serene bramble]

Having a weird issue. Added a UI animation to our menu that fades it in. Works fine when you hit "Play" and play in editor or in a separate window. But if you build and click "Launch" it doesn't play the animation. Any help??

[deep geyser]

This is the BP hierarchy

[dawn gazelle]

You can't as that's not a random integer.
What you can do is have an array of the values you want to use, then perform a "shuffle" on the array thus randomizing the order in the array. When you want to get a value from the array, use an integer variable that you increment each time you do which keeps track of what index of the array you're on. When that index tracker hits the maximum number of items in the array, do a shuffle on the array again and reset the tracker to 0.

If you have a lot of values and don't want to pre-populate an array, then you can instead populate an array with each number pulled and check that array each time you roll a number. If the number is already in the array, then re-roll your random number.

[trim matrix]

Does anyone here use WWise and knows how to use it for adding door sounds and different footstep sounds depending on what ur walking?

[tawdry surge]

Pretty sure wwise just helps you make the sounds. You still need to implement them like any other sound. #audio would be a better place to ask tho

[trim matrix]

oki

[serene bramble]

How can I make my game's source code smaller?

[spark steppe]

you can't

do you want to work with multiple people on it?

(Config), Content, (Saved), Source, Plugins and the uproject file are the important ones

DerivedDataCache, Intermediate, Build and such can be regenerated from that data

they contain mostly compiled/encoded stuff from the other directories

[tawdry surge]

I mean you can delete unused stuff and remove any platform targets you aren't releasing on

[fallen glade]

I'm getting a crash whenever I re-build this blueprint in UE5 (while it's in the level, if not it builds fine) Cold someone help me with it? Or at least help me read this? Is it even telling me what the error is? How do I find out?

[tawdry surge]

It says assertion failed, which means it expected something to be true and it's not.
The rootLOD is not the the result of that list of functions.
Why this is happening idk

[serene bramble]

It's a school project, we're required to provide the full source code that the game was built from and the build itself

We're already 7zipping the submission so it's down to 2.4GB as we're told to, but that's ok

[spark steppe]

well, you really need to only add the folders that i mentioned

and pack the build game separate

[serene bramble]

Alright

[modest terrace]

I downloaded an asset pack where the origin point of the asset is way off the mesh

can someone tell me how to fix this ?

[fallen glade]

[short pawn]

You can change it in blender

[vivid inlet]

How do I save a character's transform between levels. I find that due to using the standard PlayerStart it doesn't load in the character's saved transform I think?

[short pawn]

You have to save it as a variable to a save file and then load it when you need it

[vivid inlet]

I've done that but it doesn't seem to work.

It saves and loads the current level okay, just not the transform.

[short pawn]

You have to set position of the character

After it is loaded in

[vivid inlet]

Hmmm. Like this?

Should I add a delay maybe?

[vivid inlet]

Nope that didn't work, hmmmm. It's weird, I've followed multiple tutorials but it just won't save/load the player's transform.

[zealous moth]

is there a way to not have the epic launcher disappear when opening a project

[zealous moth]

no do it on the character itself on begin play

[thorn ermine]

Yes, its in the settings section of the Launcher
minimize to tray or something like that

[zealous moth]

😮

[zealous moth]

IS THAT WHAT THAT MEANT?!?!?!

FINALLY!!!!

[thorn ermine]

I know. not super clear

😆

[zealous moth]

so tired of opening, it closes, open it again, open another project, it closes!!

.<!!!

whack a mole

[vivid inlet]

This worked, thank you very much, dk how I didn't realise this!! Thank you so much!! 😆

[gusty shuttle]

I'm brainfarting on something
I need to simply check is the actor(s) are the same class. So I have a Parent and child in my map, and I'd like to be able to line trace and scan both and process it

But when I mouse over the child, it does not recognize it. Probably because I'm casting to the master, not the child npc

But I know there's a way to check if the actor is of x class and if so, then game on

I'm brainfarting as to how to do that for some reason haha

This works, but seems dirty

[tawdry surge]

Why not just let the cast handle it?
If its an actor of the child class a cast to the parent class will still succeed

[gusty shuttle]

See, that's what I thought to, but it was not working like we thought it would

Hence why I was brain farting haah

Actually, testing that out, it worked

This was probably a case where I made things more complicated than they needed to be

[tawdry surge]

It happens

[gusty shuttle]

Indeed. Next question, instead of casting via timer/tick, I need to make a ref to the Civilian Master/Parent class. I need a reliable way to get the object ref, any rubber duck ideas?

[faint pasture]

You want 2 actors to always have a ref to each other?

Are they both on the map at load?

or are they spawned at runtime

[gusty shuttle]

@faint pasture They are already spawned in the world. I just want to walk up to the npc, find out if I can interact with it. That's all this is really doing. It's paired up with the UI stuff too. I just want a better way than casting all the time

[faint pasture]

Do you interact with other things too or just characters?

[gusty shuttle]

Yes, other actors that are under the Use parent class

Like a gun would be under the Use parent

[faint pasture]

That should be an interface

[gusty shuttle]

Aye

Not disagreeing, I'm also trying to work with someone else's code haha

[faint pasture]

Then cast Actor to UseParent

that's gross tho

[gusty shuttle]

Interface would be ideal, but the developer who programmed this system did things weird

[faint pasture]

a character and gun under the same parent class..... ugh

[gusty shuttle]

Nope, the NPC is under Civilian Master parent. The gun is under Use parent

[faint pasture]

OK what are the base classes for everything that can be interacted with?

That's super fucky, just tell him you need an interface lol

[gusty shuttle]

bahahah fo sho

[faint pasture]

or a component

I use a component myself

[gusty shuttle]

Good call

If I wrote this from the ground up, I would of did an interface with a message

[faint pasture]

So how many base classes can be "used"?

Character, Use, what else?

[gusty shuttle]

Well to be fair, I'm shoe horning the use functionality inside the NPC

Anywho, just need a cheaper way to get the ref to the NPC instead of casting

[faint pasture]

Fuck cheaper, just cast.
Input -> Sphere trace or whatever -> choose an actor -> cast to CivilianMaster -> if failed, cast to UseParent

[gusty shuttle]

Aight, if it works (which it is right now) then screw it haha

[faint pasture]

I'd push for an Interaction interface or component tho. It'd be easy to implement as you'd just replace events and you're good.

[gusty shuttle]

Thanks man

[jagged stone]

Does anyone know how to get a point in front of the character? So for example "100" in front. I tried to do it like this, but it doesn't work correctly (I'm not good at vector math)

[faint pasture]

Forward x 100f, not forward x (100,1,1)

vector x float

right click lower pin, convert to float

[zealous moth]

1 is a valid vector length

you want 0

[faint pasture]

what no

[zealous moth]

i meant for Y and Z

[faint pasture]

he wants Forward x (100,100,100) if he did it that way but just replace with float

[zealous moth]

wut...

[faint pasture]

That would project Forward to global X axis which is his problem already.

Vector x Vector is an element wise multiplication, so if he was facing right, forward would be 0x100, 1x0, 0x0, or 0,0,0 which is obviously not right

[jagged stone]

I see that this works? Is it basically doing the same thing as multiple forward vector 100f?

[faint pasture]

That can work too

That will change with actor scale tho

[jagged stone]

I see, thank you

[spark robin]

Can I like, resample a spline to get even distances between spline points?

Im also curious, how do you see all child members of a Blueprint component or object?

Like, when you drag out from a variable/object/component/class, it gives you a list of all sorts of stuff that you can hook it up to, but what if I just want to see things that live directly under the variable/object/class/component?

[shrewd hedge]

can anyone help me with something really really quickly

how do I put my FPP camera higher than my TPP camera
im trying to make my first person camera activate first than my third person camera
even with auto activate on, it still wont work
well it will
I'll be in first person
but I'm also able to move my camera around like im in third person
so its weird
because then I can see my head when I look around

[lyric rapids]

how does one clamp camera rotation

[fiery knoll]

You can scroll down in that list to 'Variable', then look for your own class dropdown. Example:

[fiery knoll]

You can set constraints in the PlayerCameraManager. (https://docs.unrealengine.com/4.27/en-US/API/Runtime/Engine/Camera/APlayerCameraManager/)
For example set ViewPitchMin to the value you want.

[lyric rapids]

cheers

[fiery knoll]

Is there a way to have a property/variable on an actor component that can be set with a scene component of the owning actor in the blueprint editor?
Example: Set the SphereCollision as a value of the variable on MyActorComponent.

[faint pasture]

Why not just get component parent at begin play?

what are you trying to do

[fiery knoll]

I have an actor component with functionality about a bunch of trigger volumes that can be set on the actor. Would be handy to populate an array on the component with the triggers needed.
I'm looking at FComponentReference atm, maybe that's the way to go.

Seems that only works for referencing components of another actor.

I think I'm designing this the wrong way. Should probably just make a good base class with the functionality in this case.

[faint pasture]

Component can get owning actor and its components, it can discover all the volumes.

You can probably just tag the components and get components by tag on owner

[fiery knoll]

Yeah, thought about using tags, but in general I don't like them because it's less error prune.
Thanks for your help! I'm putting my functionality on the actor instead of the component.

[daring carbon]

Hi, I'm working on VR game and I have problem with UWidgetComponent ---> it's based on UUserWidget with a few UButtons and I want to trace the buttons with UWidgetInteractionComponent in my hand controller, but the UWidgetInteractionComponent is always tracing only UWidgetComponent and not the buttons which UWidgetComponent includes...

So I had this decal on the plane the (5A-DNO) Text, but problem is there's some sort of mirrored one above, how can I make it only 1 ?

Yeah, what you're describing is possible — use Get Whatever at Distance Along Spline to build arrays of data at consistently spaced points along the spline, remove all the preexisting points, then build a new set of points. It's not simple esp. if you need rolls & tangents preserved, but if you're willing to make all the functions and loops then yeah, it's possible

[bold barn]

when should i use structs vs classes in blueprints

[spark steppe]

structs for data, classes for stuff that needs functionality

[bold barn]

why not classes for data or structs for functionality

[spark steppe]

because structs cant have functions

you can still use classes/objects for data, if you want too

specially in BP world they are more robust than structs

[trim matrix]

how can I have a Light communicated with using object reference, while it is present in the level?

[naive stag]

How can I add actor to another actor to make a single actor in constructive script

[trim matrix]

using Child Actor component, maybe

[faint pasture]

You end up with 2 actors either way. What are you trying to do?

[gentle urchin]

trying to solve this problem - Interaction with Generator results in Lights being ON/OFF, that's what I am trying to achieve

[junior crown]

Hi Guys, Does anyone know how to animate skeletal mesh position on x and y using CSV data? so i can make sequences

[faint pasture]

Into one actor or an actor with another actor attached?

[faint pasture]

Generator has reference to the light. When the generator On/Off state is updated, it also updates the light

that's the simplest

[trim matrix]

I used Get Actor of Class right now, should it work?

I mean, related to performance issues as well, need to use best method

[shrewd hedge]

Hey guys, I'm using a blueprint from U4 inside of U5 and I need help with these 2 nodes. They are InputAxis Thrust, MoveUp, and MoveRight. I'm new to Unreal and they aren't quite working. There are warnings on them, and I don't know how to set them up so that they are up to date in U5. Can anyone help? I appreciate any time and any advice.

[gentle urchin]

Project config?

[dawn gazelle]

Those would most likely be set up in the project settings under your inputs.
Not 100% sure on UE5, but it's probably under Edit > Project Settings

[gentle urchin]

this sort of warning right

[faint pasture]

Add those axes and actions in your project settings

[cursive grove]

Is there any way I can call an editor utility blueprint through a construction script?

[shrewd hedge]

yeah thats what I thought of but these are InputAxis not InputActions

thank you though

[shrewd hedge]

Oh shoot I never even saw Axis Mappings

thank you!!

[astral stratus]

finally escaped tutorial hell 🙂 working on my own and it feels so good

[trim matrix]

Is there a way to find where a specific variable is used in the BP Event Graph?

Its a huge BP and I cannot find it

[remote snow]

is there a way to Merge multiple viewport assets (cubes) in to 1 so that i can use the merged object as a target in order to bypass the 1 target limitation? (found nothing online only actor merging but that only works in the ingame preview and not in the viewport) (been searching so long for a simple thing and this is driving me crazy)

[faint pasture]

Right click variable, find references

[trim matrix]

@faint pasture thanks

[cursive grove]

what object should I cast to an editor utility blueprint?

[tight schooner]

@cursive grove what are you trying to achieve? Usually an editor utility widget(?) reaches out to the world to affect objects rather than vice versa

[dusk pollen]

hi, uhm, i need help. Me and a friend wanted to connect via multi-user, but we get this error message:

do you know how to fix this?

[astral stratus]

make sure you have all the runtimes downloaded

[dusk pollen]

the patch engine version seems to be a different one, and we don't know how to fix it

[dusk pollen]

where can i check that?

[limber parcel]

i need help, my PIE session is starting detached from player for some reason and its causing errors, how to fix

[autumn sedge]

I have a how-to question.
I can use Class Reference variable to specify in an instance of a blueprint BP_ObjectSpawner what type of object it should spawn (using "Construct Object From Class") but how do i specify it's public and instance editable variables of spawned object? I don't want to subclass from spawned object type or a BP_ObjectSpawner

[cursive grove]

I want to get all the world maps and store them in a list, then access it from the player to set the actual list

Unless you have a better idea of setting a dynamic level system 😅

[limber parcel]

why are u doing this in the player and not the gamemode?...

[cursive grove]

because I didn't know any better.

[cursive grove]

You mean the level list? The character is loading the next level etc

[limber parcel]

what?

[cursive grove]

Youtube video 😅

[limber parcel]

https://tenor.com/view/vodka-shot-drinking-gif-7412608

[cursive grove]

The character has the 'level complete' 'load next level' functions

It's working as intended though 😅

@limber parcel so I'll transfer those functions there. How about the list?

How can I access the variable from the utility blueprint?

[limber parcel]

make array from folder?

do get gamemode and then get ur variable

[cursive grove]

Can you get the assets from the paths, just like you do with editor utility blueprint?

[limber parcel]

no its impossible, u cant access assets in editor

[cursive grove]

What I did was, I created a function that stores all the world maps's names into an array, and I'm trying to find a way to access this array from my Game mode's blueprint

[limber parcel]

.

ohh and i think u have to cast to ur gamemode first

[autumn sedge]

for example, i want to specify that

• one instance of BP_Rifle shoots instances of BP_APBullet that carries 5 damage
• other instance of BP_Rifle shoots BP_APBullet that carries 7 damage, and
• another instance of BP_Rifle shoots instances of BP_ExplodingBullet that carries 10 damage and 2 "explosive power"

[limber parcel]

why my PIE session keeps spawning in spectator mode? its obviously turned off in my gamemode

yes, everything worked fine before i went to sleep

everything is set correctly in my gamemode and the file didnt change

i tried reverting to an older commit but same error

[autumn sedge]

one-off items. So i want to avoid subclassing, if possible

[limber parcel]

so i guess the issue is with my editor settings or something

did that too

[faint pasture]

That's kind of the factory pattern

[limber parcel]

it works in standalone mode

just not in PIE

[faint pasture]

But you can do data only BP subclasses of Gun and do that, or make some struct that represents all the info about a gun and use a data table of those, or use a data asset but idk much about those.

[autumn sedge]

I can specify the type of bullet rifle will shoot using Class Reference, but after that i can't specify parameters of bullets, even if they are public, instance editable

[faint pasture]

You are probably going to want a struck anyway for save games so just figure out a structure that can represent anything you would care about a weapon and use that as your base data to build the object

I'm sure there's other serialization approaches but I really like just having stuffed be a plain old data truck if it can

So are they like data table entries that can exist as a separate file and can have inheritance I guess?

[autumn sedge]

Yes. In a rifle blueprint script by using "Construct Object From Class" if I plug i plug variable that contains Class Reference to, say, BP_BulletBase i will have access to variables in BP_BulletBase. However, how do i specify things that are present only in some children, like an "Explosive power" in an BP_ExplosiveBullet

[gentle urchin]

so a pure data bp

[autumn sedge]

it does look like a factory, you're right!

[faint pasture]

Yeah I still haven't really wrapped my head around exactly how all that works. I'm guessing something like a static mesh asset is already a data asset? Specifically, a data assett with a custom editor I guess

[autumn sedge]

I can't put blueprint scripts into structs and data assets. Explosive bullets from example have custom behaviour and a variable that other bullets don't have

[faint pasture]

The data asset can say what bullet to use.

You have a two level problem here. You have the gun stats. And you have the projectile. Just include the projectile definition inside the gun definition

SplodeyShotgun
Projectiles = 7
Range = 500
ProjectileClass = SplodeyProjectile

[autumn sedge]

can it say with what parameters? that it's BP_SplodeyProjectile type and also that it's "SplodeyPower" should be 10?

or should I make a data asset of a projectile with "SplodeyPower = 10" too and refer to it from rifle asset?

[faint pasture]

Idk anything bout assets but the struct/DataTable approach, sure

[naive stag]

An actor with another one attached

[faint pasture]

Just AttachActorToActor

Or use Child actor component if you have no standards

[autumn sedge]

iirc structs don't support subclassing. I will look into data assets

[zealous moth]

wait too personal

[faint pasture]

It all depends on what you need. You could easily have an AOE range, power, whatever else stat in your ProjectileData struct. Different mechanics could interpret those stats differently.

[autumn sedge]

Instant Replay Saved

[autumn sedge]

I don't think all of them can be described in 1 struct.
But i think i can make use of data assets - i can make a data asset blueprints for all actors i have, and mirror their inheritance hierarchy, and will have "spawn instance" function that would return actor asset is describing
However, I don't like that solution very much. Either i should try to automate creating them, or think of something else.

[faint pasture]

How many variations of projectiles and weapons are you picturing?

[lime fulcrum]

Hi!
Anybody has an idea on how to send Mouse Scroll Wheel to a 3D Widget over Widget Interaction Component?

[tight schooner]

@cursive grove There are many places one could store data, like a BP class or data asset or data table, but an editor utility widget is not one of those places; you should consider editor widgets/functions as apart from the game itself. They're just helpers for level design in the editor.

Not even sure if they make it to a packaged build

[autumn sedge]

If you mean in terms of inheritance - i'd like to limit that.
If in terms of different instances of the same class - a lot, especially for projectiles.
Each projectile carries list of debuffs it will apply to enemy. Debuffs also have parameters. That allows for a lot of variation.
I'd like to make it simple to add a new projectile type if game designer wants to make a new weapon/enemy

[shrewd hedge]

Hey guys I'm new to Unreal and I really don't want it to seem like I want you guys to make my game but, I don't understand much of this blueprint and I need help

I want to make it so that even if the input isnt being held down, it doesn't reduce the speed

any help would be greatly appreciated

[dry condor]

i have a button setup in my game over screen to start a new game, but when i use it in game this error happens. why would this happen and how can i fix it ?

im doing basically the same thing with my "back to main menu" button and it works just fine

edit: i just found out this is only happening when i am in Level01

[faint pasture]

The select node chooses one of the inputs for its output based on that boolean. If you don't want acceleration to decay, just get rid of the select node

Do you follow any of that code at all?

[fallow umbra]

Hello guys, does anyone have an explanation for this? Cause I'm losing my mind

[faint pasture]

Remember the debugging is a snapshot in time. You might have already updated one value but it hasn't propagated to the rest yet.

Show more of the code so we can see WTF is going on

[fallow umbra]

I have advanced a few steps too

[fallow umbra]

between for loop body and Sequence is just a plain print node, no logic

[cursive grove]

I can actually get path and actors of specific class through the game mode, so...

[shrewd hedge]

barely. I'm just following along with tutorials. Once I'm finished with this game, I'm done with game creation forever lmaooo

but thank you

ill try it

@faint pasture like this? If so, what do I do with the Get World Delta Seconds node

[shrewd hedge]

nope not like this I've encountered a bug, when I start the game, the ship flies at a decently fast speed, and when I accelerate it stop the ship completely

[faint pasture]

CurrentSpeed = CurrentSpeed + Acceleration* Input * DeltaSeconds

That's what this function should do.

The clamp is enforcing a max speed

[shrewd hedge]

I fixed the bug, the ship works fine, but now theres no deceleration

lemme try to fix it

one sec

[shrewd hedge]

😮

code that i dont undestand

oh yeah thank you btw

[faint pasture]

Then why are you doing this. This is exactly the problem with tutorials, you just tag along without understanding what you're doing and then wonder why you're lost. Do you know anything about programming at all?

[shrewd hedge]

im doing this because I want to create the game of my dreams

and no I don't understand coding much

[faint pasture]

I'm not trying to be snarky. I'm just literally asking if you know programming before this or if this is your first introduction to programming.

[shrewd hedge]

I do understand nodes tho coming from blender

but blender nodes and unreal nodes are different obviously

[shrewd hedge]

this is my first introduction kinda

i made a game in unity... following a brackeys tutorial

[dry condor]

math, math and MORE MATH, thats what you need 😄

[shrewd hedge]

gotta love C#

[faint pasture]

So what kind of game are you trying to make?

[shrewd hedge]

a space simulator

a space flight simulator*

it'll be bad but I don't really care

but I want it to be atleast workable

so im finding my way through the internet

[faint pasture]

My first question is, do you want it to be physics-driven or no?

Cuz what you got going on is not physics driven, it's just doing your own movement.

[shrewd hedge]

no, not physics driven

the ship I'm using can defy the laws of motion and gravity

[dry condor]

hey adriel, would you happen to know why this error happens and how to prevent it ?

[faint pasture]

You can still do that with physics. It depends on what you're going for, but things like collision, coasting, drag etc are much easier with physics. What do you want to have happen if you hit something?

[faint pasture]

What does BPIResetGame do?

[fallow umbra]

so any idea about WTF is going on ?

[dry condor]

setting Lives and Score to default values

[shrewd hedge]

I would like the ship to take damage or even explode if it collides with the object hard enough but I think I've got that part

[dry condor]

its only happening because the level is allready loaded i think, because the error only appears when i am in level01

[faint pasture]

What is this trying to do? It's pretty unreadable.

[faint pasture]

I mean do things bounce?

spin if hit,

anything like that?

[shrewd hedge]

No not yet

[faint pasture]

You gotta remember if you're doing all the moving by yourself, you gotta do ALL the moving

I'd recommend using physics. You'd just add force to thrust, and optionally implement drag by adding force opposite your velocity if you wanted space drag

[shrewd hedge]

okay

is implementing physics harder than what I'm trying to accompolish

I don't even know where to start with physics

[faint pasture]

No it's easier

It'd just be
AxisEvent -> Add force
to start out with

You'd make a Pawn with a mesh as its root component, have it simulate physics, have it ignore gravity

IDK what your camera setup is but it'd be the same, you can probably turn your current ship into one that uses physics

Show your component outliner (top left) in the BP editor

[shrewd hedge]

yeah I just disabled the mesh's gravity

I made it simulate physics now

[limber parcel]

lol are u working for lucas arts?

[shrewd hedge]

for sure

lmaooo no I just really love the ship

I've always wondered what it would be like to fly one

[limber parcel]

download star wars battlefront 2 😄

[shrewd hedge]

NO.

I have it

I wanna do it in 1st person tho

Yoda's isnt good

[faint pasture]

OK that's good. Enable physics on mesh, disable gravity, then do
InputAxis -> AddForce on Mesh

Force being AxisValue X 1000 or so, and check Use Acceleration on the AddForce node to make it ignore mass

Er rather

AxisValue x 1000 x self.forwardvector

[shrewd hedge]

I don't have a self.fowardvector 😬

is that a different node

[faint pasture]

yes you do

just right click adn start typing forward

you'll find it

[quasi vault]

how do I set a character to player start? I want to add another character but when I add another player start I relised that I dont know if you have to set a certain sprite to player start. By the way, this could is a bad way to do this but Im just experimenting

[shrewd hedge]

"get forward vector"?

[quasi vault]

do I have to state something in a blueprint or something?

[faint pasture]

Are you trying to add a 2nd character or have the 2nd character start at a different location?

[shrewd hedge]

under transform or vector

[mossy perch]

The docs didn't make me any smarter on the case tho =/

[faint pasture]

#animation

[shrewd hedge]

i should stop asking so many questions

im sorry

aaa

[faint pasture]

Just try stuff. Get Actor Forward Vector will work. You want the forward vector of the actor, which is itself

[quasi vault]

well, I wanted to get rid of the first character once I set the second characters blueprint and location on the map

[shrewd hedge]

okay thanks

[dry condor]

honestly you should try to understand what you are doing and how UE works, no offense

[shrewd hedge]

i know

none taken

thanks anyways

I dont wanna seem like you guys are making my game for me so I'm gonna go try to figure this out on my own

thanks for the help though

I really appreciate it

[faint pasture]

@shrewd hedgehttps://www.youtube.com/c/MathewWadsteinTutorials/playlists

[shrewd hedge]

YES

THanks

Thanks*

I've been using Matt Aspland

[faint pasture]

Just go look up the WTF is whenever you find a node and you're not sure what it does

[dry condor]

Adriel posting Tutorials 😮

[faint pasture]

They aren't really "hold your hand and tell you what to do" tutorials, but just quick little explanations.

[dry condor]

and then you want to look up what a node does or how it works with other nodes and get something like this https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Game/OpenLevel_byName/

[shrewd hedge]

the only good and accepted tutorials

Adriel Approved Tutorials

[faint pasture]

@shrewd hedgehere's your first assignment. Make a custom event in your ship, and have it teleport the ship 10,000 units forward.

Then add a new InputAction, and hook it up to that event. So you can press button -> teleport

[dry condor]

hmm hacked my way around it but i dont really like my solution, because now i must have a duplicate of level1 😄

[faint pasture]

What are your options in the dropdown for the open level node

[dry condor]

"absolute" and "opions string"

node docu wasnt helpful with the options for options string

the error was/is only happening when i am trying to load the level i am currently in

[shrewd hedge]

wait guys I was just doing more stuff and somehow my axismappings got deleted and idk how

but now I cant walk forward backward left right

etc

look around

and idek how since I wasn't even messing with the axismappings

[faint pasture]

walk? I thought u had a space ship

Are the mapping deleted or just the events in the BP graph?

Project settings -> input

[faint pasture]

Try absolute

[dry condor]

absolute is apparently just to reset the options set with the options string

it sadly didnt fix my issue

[fallow umbra]

Thanks for the tip 👍 , I've used the Blueprint Debugger window and I figure it out

[faint pasture]

What was it

[shrewd hedge]

yeah I know I'm trying but S is making me walk forwards and A is also making me walk right and the mouse is making the perspective look weird, no clue what happened

[faint pasture]

So why are you opening the same level you're already on?

[shrewd hedge]

im gonna make it so that you can hop in and out of the spaceship

[faint pasture]

What is this in, gamemode?

[shrewd hedge]

i wasn't messing with anything mapping related, it just happened somehow

I know idk anything about coding but trust me, I wasn't messing with the mapping

[dry condor]

game over in that level and then clicking "play again" button in game over screen

[faint pasture]

Start small. Get the walking dude OR the ship to work right now.

[shrewd hedge]

I have both

the ship is starting to walk

[dry condor]

this is in game over widget

[shrewd hedge]

work**

[faint pasture]

You just got your learner's permit, don't start off with an F1 car, start off with a go kart.

[shrewd hedge]

that is actually

wtf

thats inspirational asf

but yeah I had the walking dude

i started with him

but for some reason

[fallow umbra]

the bug was a logic bug on my side, real values didn't match the ones that the live debugger showed (Blueprint Debugger does show the actual ones)

And about why the debugger showed me the wrong values, I don't know.

[shrewd hedge]

he got messed up out of no where

im fixing it rn tho its fine

[faint pasture]

So are you meant to be walking around on a moving ship?

Or is it like GTA where you're either driving the dude around or the ship.

[shrewd hedge]

its like gta

but that first idea isnt so bad

[faint pasture]

OK so you possess ship to drive it.

The first idea is hard as fuck

[shrewd hedge]

i might learn how to implement it

[shrewd hedge]

yeah i can sorta wrap my head around how its supposed to work

[faint pasture]

The character movement component implies and relies on Z being down etc. It doesn't play nice with things that can be upside down and rotate all over the place etc.

[shrewd hedge]

lmaoo yeah

it would be cool if there was a feature where

you can like

add gravity

to a certain

location adn rotation

[faint pasture]

Unless you did physics walking too, that'd be what'd I'd do. but it'd be too much for a first project.

[dry condor]

you would have to stick the character to the ground like a magnet 😄

[shrewd hedge]

so it doesnt have to be down

it can be up

or sideways

[shrewd hedge]

pretty much

[faint pasture]

If you did physics walkign that'd be easy.

also, if your ship took off and you weren't seated, you'd slam against the back wall lmao

[dry condor]

or no gravity fly through the ship

[faint pasture]

Yeah I'd do all physics driven for a space game but you better NOT even consider multiplayer

[shrewd hedge]

YES thats a really cool feature

[shrewd hedge]

heh heh hehhhhh 😈

the possibilities are endless once you are the creator

MWHAHAHWAH

joke

obviously

I'm like 90% sure this idea I had would fix my walking dude

[dry condor]

until the turorial ends 😉

jk

[shrewd hedge]

is it weird that I'm listening to the minecraft soundtrack while making a space game

im not weird

its just

i can explain

okay I fixed the walking dude

I'm a genius

not really

[faint pasture]

Here's what you can do with physics walking, I whipped this up in like 20 minutes a long time ago.

[shrewd hedge]

it was a simple idea

[shrewd hedge]

YEAH thats what I was talking about

[faint pasture]

Much easier with physics then trying to wrangle the character movement component into playing nice.

[shrewd hedge]

right here

[faint pasture]

just forget about multiplayer, completely

[dry condor]

like mario galaxy

[shrewd hedge]

yeah i was never going to add it

maybe like 10 years in the future

when and if I recreate this project

[faint pasture]

Then do it all physics.

[shrewd hedge]

good idea

[faint pasture]

It's the simplest, just gotta be comfy with forces and torques etc

[shrewd hedge]

i mean without physics this game is working just fine

well the dude has physics, the ship doesnt

but it's still working fine

[idle maple]

i need help asap

[faint pasture]

and what stops ship from flying through something?

[idle maple]

my question is simple

[shrewd hedge]

absolutely nothing

[idle maple]

im making endless runner game

[shrewd hedge]

just be a good pilot

ez

I'm adding a roll rn, I got the idea of just mocking a jet

[idle maple]

and there will be floating enemy big spheres on the sides of way
and they re shooting special bullets
and i want to program bullet simply

[shrewd hedge]

and there are tuts out there

ill stop talking now

[idle maple]

bullet to go to current location to player

like self aim rocket missle

[faint pasture]

Can it miss?

[idle maple]

nope

[faint pasture]

does it always hit or does it home in on them

does it go through stuff?

[idle maple]

hit or get blocked

blocked by lightsaber of main character

but it is supposed to always hit, and dont get blocked by other objects

[dry condor]

there is an option for "is homing" or something in the projectile movement component

[idle maple]

this one isnt workin

[faint pasture]

Either use the projectile movement component with homing with very high acceleration, or make your own bit of code that just updates position towards TargetActor.Position

[faint pasture]

Why would it

Make an actor with the projectile movement component on it, play around with it

[idle maple]

(im newbie 💀)

[idle maple]

thank u

[dry condor]

AI Bullets sound interesting xD

[idle maple]

this one inst working too

@faint pasture help

and should i stop watching tutorials?

[shrewd hedge]

isnt that technically just aimbot

[faint pasture]

ya

[dry condor]

yeah and shooting around walls or w/e too 😄

[faint pasture]

What are you expecting that to do

Make a bullet actor

give it a projectile movement component

and a collider of some sort(mesh, sphere collision, box, whatever)

play with the projectile movememt component settings. Put it in the world, hit simulate, see what it does

Get it to fly

[idle maple]

i made actor bp and gave it sphere static mesh

[idle maple]

in what way

[faint pasture]

k so give it a projectile moement compoentn too

[idle maple]

i mean i can add it but then?

[faint pasture]

Then mess with its settings for speed and velocity and bouncing and gravity and homing and whatever else

then drag it out into the world, hit simulate, and watch it go

[dry condor]

set initial speed, put it in the world and watch it go brrrr

[faint pasture]

Then later make your enemies SPAWN it at runtime

[idle maple]

i wanna make it following player just when bullet spawns

[faint pasture]

Sure, make the mesh the root component is what I like to do but that might work

[idle maple]

so how can i trigger it?

[faint pasture]

make the damn thing move at all first

[dry condor]

patience young padawan

[faint pasture]

I want to make an MMORTS too but I haven't made the M or the O or the RTS yet so I'm not doing that.

[idle maple]

yeah but how

[idle maple]

so how can i learn all of it

[faint pasture]

#blueprint message

[faint pasture]

How did you learn how to use a computer? Did you watch lessons on it or did you just sit down and mess with it.

[idle maple]

mess + google

to find applications etc

[faint pasture]

Keep that same energy.

These are great.
https://www.youtube.com/watch?v=AM3TXKI-4co

[idle maple]

but in that case should i google and watch what?

[idle maple]

thank u

[faint pasture]

Just keep it bite sized. Following along to a 50 part series on "how to make an mmo in unreal in 30 days" isn't very good because you'll get lost instantly. Watching "What is an actor in unreal?" is good because you're learning the one thing you're stuck on, then you go back to struggling on your own to do the thing.

[sterile jacinth]

Hello, I'm trying to separate world model from first person model in online environment using listen server. I use these nodes in my sword blueprint.
On server everything looks fine. But on client everything is mismatched (server holds sword in first person and client holds sword where his third person hand should be)
What might be the problem?

[faint pasture]

You aren't selecting on anything

Why don't you run 1 mesh component but swap the actual mesh out depending on if local client or not?

Nobody needs to see the 1pp mesh but the local client right?

I see MY 1pp mesh, everyone else everywhere only sees the 3pp mesh

[shrewd hedge]

hey I need help with this physic thing, everytime I click the start button, since my mesh is divided into 2 parts (the auxiliary and the main hull), they just come apart and kinda explode away from eachother

I tried parenting the aux to the main hull but still

[dry condor]

i guess they are colliding with each other

[shrewd hedge]

how can I fix that?

[faint pasture]

Don't simulate physics on the child

and make sure you have auto weld turned on

[shrewd hedge]

okay thank you

problem, it's saying that I need to simulate physics on the child in order to have torque

wait hold on

no not the child

im stupid

it says the plane

but I can't add physics to the plane

[faint pasture]

Why not

Start with no child meshes

Just 1 mesh that is simulating physics

[shrewd hedge]

okay I did it

it works now

buuuuuut of course theres another problem

when I star the game the camera is infront of the ship for some reason

it looks like the ship is going reverse

I see the problem

for some reason the bum camera got moved somehow

wtf is going on man 😭

well I fixed the camera

but now the ship is actually going reverse

im a great programmer 💪

im gonna stop spamming this chat now

its a bad habit

sorry everyone

[faint pasture]

Show the ship BP

X (red) is forward

[shrewd hedge]

its a really big BP

[faint pasture]

Show the 3d view

with all the components

[shrewd hedge]

in the viewport?

[faint pasture]

ya

[shrewd hedge]

got it

I think i see the problem

the ship is rotated

but it doesn't say its rotated on the side

[dry condor]

because this is how you imported it

so thats rotation 0,0,0

just rotate it 180 and you are good to go

[shrewd hedge]

okay thanks

yet another problem

I made the main hull part the parent of all the components

I cant rotate it

I can only rotate the auxilery

[teal talon]

Question: I have an array. How do I ask " If all are true "Player Ready" then do x"

[faint pasture]

Don't do that

don't ask widgets

widgets are local only, they should only be the VIEW of the data

where is the source data for if a player is ready?

Should be a bool on PlayerState probably

[teal talon]

In the widget this is all single screen local. But there are 6 local players setting to ready. I need each time a player click ready to check if everyone is ready.

[hardy spoke]

Anyone have any good advanced movement blueprints? Titanfall style movement

[dry condor]

i think the lyra project has a pretty good one iirc

[faint pasture]

ok so you set a bool true, then set it false if anyone is not ready. If it's still true at the end of the for each loop, everyone is ready.

bStartGame = True

Foreach Whatever in WhateversArray
bStartGame = bStartGame AND Whatever.bIsReady

after loop
read bStartGame

that's the branchless way to do it

[teal talon]

I love it, thank you

[mental trellis]

You can break the foreach loop if you find 1 person who isn't ready too

Not that that really matters too much, but yet.

[faint pasture]

ya that too

get all 100 of your buddies on the couch and save that perf

[sterile jacinth]

I need third person mesh for damage, I put a trace on sword that deals damage if it collides with playermodel. And what do you mean by "swap the actual mesh out"?

[tawdry surge]

Set the mesh asset your mesh component is using to something else

[vapid ibex]

How to create persistent ID for objects and actors that would remained the same between game launches? (lets say I need it for a save system of sorts for instance)
I've found people saying that I should use GUIDs, but it seems that the only way to generate GUID is to create a new completely random one? So I do not know how to assign same GUID to same actor every time level loads (and how to assign GUID to some non-actor assets altogether). What should I do?

[blissful widget]

Are these actors spawned in the world or to be spawned in later?

[cyan bone]

Im dealing with a very tricky challenge.
I made VAT from a skeletal mesh, using the VAT plugin.
The VAT automatically resets the pivot point to the bottom of the static mesh.
And me like, "huh ok i can just set pivot point" 😏
But then that screws the VAT entirely. What should i do?
I tried all kinds of tricks.

[cedar sparrow]

Is there a reason to use Text or Name variables over String?

[dusty schooner]

Hey all! Silly question but what exactly do I use for && and || operators in Blueprints/UE5?

(I've been googling the past hour and have found nothing useful)

[north onyx]

Text is generally used for localization, The Name are case insensitive and used for simple things. The string is between of them but more functional rather than Name.

Use Name if you just give it a name. Most efficent in C++ mostly in BP's too.
String is combination of names you may think, more handle but not localized.
Text is mostly common to representate in localizatiom especially for Menu UI Text's, cinematic subtitles, a text can be appear different of languages.

[cedar sparrow]

gotcha

[north onyx]

Search, AND for &&
OR for ||

[cyan bone]

@north onyx you seem knowledgeable. can you help me with my problem?

[dusty schooner]

I tried both of those. OR doesn't return anything under Operators (but everything under the sun that contains "or")

Oh I see them both now. They're under Math > Logical Operators and not plain Operators. My bad 😅

[tawdry surge]

Most things will just come right up if you use context sensitive and pull from the relevant pin

[north onyx]

Sorry, i don't know about VAT and 3dsmax tools. I'd go rather make a contact with plugin developer.

The Vertex Animation 3Ds Max script offers two different ways to store the vertex animation data. One method will store the vertices positions in a 2D Texture while the other method will store the vertex position data in the UV's of the mesh. Below you will find links that show you how to setup and use both methods.

Key framed Method - This method uses individual key frames that can be exported from other 3D packages and imported into 3Ds Max. That information is saved to the meshes UVs.

Animation Timeline Method - This method uses the 3Ds Max animation timeline and the results are encoded into a 2D Texture.

Here is what may be related with your provlem. I found this on offical docs.

https://docs.unrealengine.com/5.0/en-US/vertex-animation-tool-in-unreal-engine/

[cyan bone]

yes thats the one im using VAT

[north onyx]

Maybe you exceeded the limitations

[cyan bone]

thats working great. now the issue is the pivot point being right under the feet

im trying to make it on the chest of my units

nothing is working. maybe its not possible and ill have to get over it

i tried merging actors and setting pivot point zero

and using mesh bake tool

[north onyx]

@cyan bone https://forums.unrealengine.com/t/how-do-i-change-the-pivot-position-on-a-component-in-a-blueprint/289439/2

[cyan bone]

that changes the pivot point of the static mesh in the level

but not in the actual asset

[north onyx]

Yeah

https://youtu.be/UAhxIsroAPg

[cyan bone]

so in case you need to use them in the construction for example, then it must be in the asset

[north onyx]

Hmm

[cyan bone]

yes that one too. it wont work

i think i will have to get over it and work with the weird pivot that i have

[manic adder]

hi. i have an interface that sends a vector to a 'dynamic sky' blueprint via an interface. how can i similarly send another vector to a bp that controls 3 pointlights ?

[dusty schooner]

Another silly question (I appreciate the help): I'm attempting to grab input from a character to use in an animation blueprint on the same pawn. I've been trying to access the variables in the default BP from the Animation event graph with try get pawn owner but I'm not seeing anything yet. Is there a good way to pass variables like this?

[rose charm]

I think you can use a blueprint interface

[manic adder]

*sorry for repeating 'via interface'

[rose charm]

you are not seeing the variables because the get pawn owner will get a default class pawn, and you need a reference to your pawn class

[dusty schooner]

I'll have to look into that. I'm coming from unity and normally I would just try GetComponent<ScriptName>.Variable(); 😆

[dusty schooner]

That makes sense! Is it going to reference the current instance of the class or the default definition?

[rose charm]

you can use interface too, you will need a reference to this other bp

[astral stratus]

https://gyazo.com/d4ef7edb3516948c6f5c2f23d10c4d3e anyone know why i might be getting this...? https://gyazo.com/3fc7f24898cd918d8b4020c135635c87
https://gyazo.com/c60a282a7411619c3b395f2c0892ffd3

[manic adder]

if i convert a light to a bp, i cant target that bp in the sender

[rose charm]

if you only use get default pawn you will get a reference of the default pawn class, you can use cast too, to cast to your pawn class, but it's better to use interface

[dusty schooner]

Gotcha.

[rose charm]

so the lights are on the level but are not a blueprint actor?

[manic adder]

lights are on the level. didnt figure 1) how to merge them into one bp (only figured how to convert a light to a bp, but it wont work for multiple selected lights) and 2) how to make the lights bp of a class that is accepted as sender target

[rose charm]

where are you setting the character variable?

[astral stratus]

in my UI

then pulling off my character to "add score"

[rose charm]

do you want a blueprint with the 3 lights on it?

[manic adder]

yes

[rose charm]

this variable is returning none, maybe there's a problem where you are setting it

[rose charm]

you can create an new actor blueprint and add light components on it

[astral stratus]

not sure why it would be returning none...

[rose charm]

can you send a screenshot on how it's being set? the Character var

[manic adder]

can i add existing lights to a new bp ?

[astral stratus]

@rose charm https://gyazo.com/3da2037e9f987808408cb2cfe828bedd
https://gyazo.com/31ad7b51a3bf78f73c93921a0402dd45

[tawdry surge]

Your ui shouldn't be calling the player from the widget anyway. Character should be passing the score to the widget when it changes

[rose charm]

you will need to replace the 3 lights on your level with the blueprint actor, on the actor you can set the lights transforms to be the on the same location it was on the level, I don't know if this is what you want

[rose charm]

you just have the variable but isn't setting the reference?

[manic adder]

i need to be able to set intensity of multiple existing lights in a bp. i dont know how to replace the lights, and with what

[rose charm]

from what do you want to set the intensity? another bp?

[manic adder]

from a separate blueprint (kinect hand vector)

[astral stratus]

@rose charm im just a bit confused right now because I followed what i did from another project and it dosnt seem to be working

[rose charm]

you will need a reference to the lights on the blueprint, you can save the reference on variables of the light class, instead of creating a blueprint to the lights. with or without an custom blueprint actor to the lights you will need the reference to it

[rose charm]

by the screenshots you send you are not setting the character, only declaring it, but with no reference to the real character

you will need to do something like this(casting to your character class), but like MW_WHDS said you shouldn't be calling the player from the widget

[manic adder]

by reference you mean what goes into the target of the sender function ?

[rose charm]

yes

but you can do it without interface, if you have a reference to the light

[rose charm]

it won't work.
this blueprint will be placed on the level too, or will be spawned later?

[manic adder]

and how can i add existing lights from the level to my kinect bp ?

[manic adder]

bp is in the level

[rose charm]

the kinect bp is on the level?

[manic adder]

yes

[astral stratus]

@rose charm got it working!

[rose charm]

maybe you can check this option, then you will select it on the actor, click on the kinect bp placed on the level and it will be on the details panel

[rose charm]

click on this icon and then select the light on the level

[tawdry surge]

It'll show in the details of the one in the level now. Set it there

That's how you set a direct reference

[manic adder]

what will show? pipet active ?
details of the one what ? light ?

[rose charm]

it will show on the details of the kinect bp actor placed on the level

the variable will show there so you can set the reference

[manic adder]

cool thank you for your time and for the basic lesson

[faint pasture]

Scale is a vector

Break it if you want

https://tenor.com/view/tardis-doctor-who-gif-18874463

bruh

[upbeat otter]

is their a way to "extend" the characters collision? I have a cube attach to the character that sticks out from the pawn capsule and I want the cube stop the player from moving once it hits a wall

[limber parcel]

have u tried just enabling collision when its attached to the player?

[junior hedge]

I honestly think what you are looking for is rendering the cube in a different camera

[junior hedge]

nvm looks like it is not possible

[livid marlin]

im using master Pose and i hope the line trace can trace bone name

how can i do it

[desert juniper]

the easy unreal way to do is is to spawn the cube really really close to the player, but much smaller

unreal doesn't have overlay cameras like unity does unfortunately

[dark crow]

There's a literal hit bone name out hit result

[junior hedge]

Any idea how a game like Valorant does it?

[desert juniper]

I don't. i don't know if they've had any talks on that

[junior hedge]

I heard an idea of them using a PNG but doesn't make much sense

[west creek]

I'm trying to use an animation sequence as a variable. Anybody know how to plug it into say a blend pose?

[desert juniper]

I remember reading that you can render another camera ontop of the main one, but you'll need to modify the engine itself, since it doesn't have the functionality built in

[junior hedge]

Gl and maybe #animation is better here

[desert juniper]

there's a few products on the marketplace that impliment a fix for this issue

[junior hedge]

Ic

Any links?

[desert juniper]

I haven't used any, so I can't recommend any

but I did find this https://www.unrealengine.com/marketplace/en-US/product/weapon-fov-and-clipping-fix

interesting. I see there are some ways of doing the same with shaders too

[dim tapir]

Good morning team, I am trying to make a rather simple "press button again to trigger". I can't find any guides for this. Is there a function that does this, like sequence?

On first press do X
On second press do Y

[surreal peak]

Theoretically a flipflop. That will go back to X on the third press though

Otherwise a branch with a boolean fwiw

[dim tapir]

Fwiw?

[surreal peak]

For what it's worth

It depends on what your third button press should do

[dim tapir]

What I want is to spawn a projectile on press and then destroy the projectile on second press. If I use a branch I'm not sure how to "call" the projectile to destroy it

[surreal peak]

Then you can use the reference to the projectile

The spawn nodes return value is the projectile you spawned

You can save that to a variable and use the variable with an IsValid node to check if the Projectile exists

If it doesn't exist (Not valid) spawn it, save it to the variable.

If it does exist (valid) destroy it and set the variable to "nothing"

[dim tapir]

I don't think I understood. So I spawn the projectile, set the return value as a variable, check if it is valid.
If valid, destroy
If not valid, set delay.

My issue is that its always valid, even if a projectile is spawned.
I'll try to get an image for you

[gentle urchin]

wrong order

[blissful widget]

Are you only ever setting the Spawned flag after spawning it? It'll never be false

[gentle urchin]

Spawn should happen if the projectile is not valid

[blissful widget]

Unless it's defaulting to false of course, but that's not what you are after

Roughly, you want to do this I think:

ability2():
   if spawned:
      boom()
      spawned = false
   else:
      spawn()
      spawned = true 

[junior hedge]

I'm confused

Why exactly can't you just use the branch to destroy it?

[blissful widget]

Because you're branching off a value you've just set, IE it will always be the same value. You want different behaviours depending on whether there is a currently spawned one or not.

[junior hedge]

You would just set it to the opposite value after running, I see no problem here

[blissful widget]

It will only be false if the SpawnActor node fails, which shouldn't really happen in normal circumstances no?

Also, don't name non-booleans things like Is ..., it suggests it's a boolean but it's actually an actor reference of some sort, which is pretty confusing

[junior hedge]

I'm not the person asking the question

I feel like this is being overcomplicated so much though

[blissful widget]

IK, that was feedback directed at them

[junior hedge]

You could just create a boolean called bIsSpawned

[dim tapir]

You mean like this?

[gentle urchin]

Overcomplicate?

Bool vs isvalid check ?

[junior hedge]

After 2 seconds it would create another actor

You should probably make 2 booleans in this scenario

[blissful widget]

The only thing is you don't have timeouts which I thought was needed? Super easy to add to this one though

[gentle urchin]

Guess i missed that part

timeout

would be the projectiles LifeSpan

[blissful widget]

I'm not sure what exactly the timeout dictates though

[dim tapir]

Yeah, perhaps I should mention that I'm a complete beginner to both programming and game making. Started a few weeks ago after watching some youtube tutorials

[gentle urchin]

timeout being a moment in time where the projectile explodes either way ?

[dawn magnet]

Hi, I made a simple Control Rig that I want to bake an animation to. However, when I want to Bake to Control Rig, it's not there. Editing with FK Control Rig works as expected. The only thing I found online so far is that I need to enable that option to see it in the context menu, but I can't find that anywhere.

hmmm, looks like I need to implement a backwards solve

[rose flower]

Is it possible for 2 different instance (but the same object) of UI widget to share/use the same variable in blueprint?

Like how you can use 2 different pointers in C++, but it points to the same object

[limber parcel]

by accessing them from gamemode or whatever other source u want

https://tenor.com/view/einstein-smart-think-thinking-idea-gif-15488934

[rose flower]

Can it be done from the UI widget graph?

https://cdn.discordapp.com/emojis/861177300300333086.webp?size=48&quality=lossless

[limber parcel]

try it

Ye, im trying it rn

[wicked osprey]

Guys, do you know how to reload an incompletely spent drum of revolver cartridges? With the condition that he reclines the drum.

[junior hedge]

?

[gentle urchin]

Recline the drum is a phrase unknown to me

Then again i dont know much about guns in general

Do you mean just to reload?

[eternal cairn]

What do i do if i want to make a base class for a type of physics objects, but i want to use different collider shapes depending on the child. Being forced to have a specific, non-overridable root component is making it difficult.

I thought about making the functionality into a component that i can just slap onto my BPs, instead of using inheritance, but i need timelines for the functionality i am doing.

[gentle urchin]

You could make the initializing function in the parent bp,
