blueprint

[olive yarrow]

Battz (and others) absolutely rock shit on #animation , you'll be in good hands

[trim matrix]

ive made this snowball that grows when the player pushes it, but now i wanna add in being able to "stack" them into a snowman if they are big enough, i made a snowman bp to spawn for it but im not sure how to check if the snowball is big enough when it hits another one,

[faint pasture]

What repreents how big a snowball is?

What is the number that go up when its rolled

Cur Size right?

[trim matrix]

yes

[faint pasture]

And the 2 snowballs hitting are the same class right?

Hit -> check if OtherActor is also a Snowball (cast) -> if my CurSize > OtherSnowballs CurSize and my CurSize is big enough to make a snowman -> disable my collision, disable other snowballs collision, spawn snowman, destroy other snowball, destroy self

assuming thats how you want a snowman to show up, you could just stop self, attach other to top of self, and have 2 stacked snowballs, however you wanna do it

[trim matrix]

yes

[faint pasture]

you wanna check if your cursize is bigger than the other because BOTH snowballs will run this code, so you need only one of them to proceed to making the snowman

just let the bigger one call the shots

[remote flare]

OK just posting this here in case anybody later runs into a similar problem as myself. It occurred to me i could just write a simple blueprint callable function that was pure which checks the flags and returns true or false if any are set:

https://i.imgur.com/SWqCq91.png

[trim matrix]

so like this?

[faint pasture]

That's about half of it

but sure

that will spawn a snowman at the world origin if 2 snowballs hit and one is bigger than the other

[trim matrix]

ik just wanted to make sure i was going the right way

[trim matrix]

how can i spawn it at the location they collide at?

@stone field Blueprint that works in editor, but not packaged

(will hit Row Found in editor, will hit Row Not Found in packaged build (debug) )

[stone field]

I would start by sanity checking:
append or formattext more info to the Not Found PrintString: add the EnumToString to check what is going on
( can also try this with blueprint breakpoints of course )

[meager spade]

I would personally never count on enum to string out of pure principle

[verbal girder]

I was hoping to just have the enum convert to a row number, but, couldn't get that working

[meager spade]

Just do a map with your enum as key and name as value

[stone field]

I haven't had problems with, but of course use actual enum always when possible

for datatables I usually just have the rowName as the enum string, but granted the Map is much more robust option ( I always have enum as well in the struct )

[verbal girder]

I'll try that out if I get this working, i'm new to C++ and converting the Enum from an unreal enum to a C++ enum was kind of a headache

bricked the project for a while and I had to root out some files heh

(Packaging build now for the print string, Karma. It acts as expected in editor)

[faint pasture]

What have you tried

You're using overlap so there is no "location they collide at", but there is the location the bigger one is when the overlap happened.

[verbal girder]

@stone field Ignore the double hit, basically the Enum To String is printing out the same, but not finding a row name now.

Except for Empty, which it does find.

Interestingly, I had the data table print out all its names at game on:

[autumn pulsar]

What do people here usually use for Source Control on an Unreal Project?

[verbal girder]

Github, which I hook up to the revision control. I also have an LFS plugin, so I can lock files, but I hear using perforce for that is much better.

[verbal girder]

Weird that here, its names are different. I'm going to track that down

[autumn pulsar]

Are you using a local repository?

I have a NAS I wanted to use

[verbal girder]

Nah, remote

that'd be cool tho

[stone field]

Try delete intermediate and binary and rebuild ( if haven't done so already )

[verbal girder]

It appears in the build that it doesn't print out the tostring

and will do now

[stone field]

if even that doesn't help, might be good to check the "resolve offline work" in p4v ( assuming p4 )

[stone field]

dev builds should print to logs

or then it's not even getting there in the logic sequence

[runic parrot]

There's still no way to bind a rich text ?

[verbal girder]

Fixed. This did it, I just got frustrated and made it say its own name this way lol

¯_(ツ)_/¯

I'll have to figure out less hard codey ways of doing that in the future, but, oh well.

[high gale]

can anyone tell me how to compare distances between actors? I need to check to see if these two actors are within 600 cm of eachother for something to happen

[maiden wadi]

V1 minus V2 and then get that new vector's Length.

[high gale]

so like this?

[autumn pulsar]

Solo dev so I don't care too much about checking in and out

How did you set up yours?

[verbal girder]

Like the steps? Configured a github repo, i use both command line and github desktop, because sometimes i have to fix things my two other devs do (they dont use their own branches). Well I'm down to one other active contributer besides me.

Then I hooked up the revision control in the editor, although I will admit I very often use github desktop instead, since I'm the primary code contributor.

Solo id just make sure everytime i get one thing done to do a commit and describe it well, bug fix or new feature or whatever. Especially important for unreal binary files that tell you nothing

Oh there's a #source-control btw

Theyll be much smarter than me

[summer coral]

so im attempting to set a characters location based on a location on a different object and i can get the location fine, however i am having 2 strange issues with it:

1: I can't garentee the location of the object will be on the ground and would like to just move the player in the X and Y and let the Z be whatever is 'on the ground' for that spot but if i use the players current Z werid calcuations start to happen
2: im a first person character and when i set the rotation of the actor the rotation doesn't acutally change. I assume this is becuse the player camera is attached to the player controller and 'set actor rotation' doesn't set the controllers rotation, however i can't really find a good way to set the rotation that doens't involve math in figuring out the yaw and pitch to add using the 'add controller yaw input'

anyone have any thoughts?

[autumn pulsar]

could do a shape trace with the player's capsule to find a valid spot

or if the player's size is a known quantity that won't ever change you can just hard-code the offset

[summer coral]

I did attempt a hard code of the offset, however the spot may not be on the ground each time so the offset would vary depending on where the location is, but that is a good idea. I have done line traces and capsule traces, are those the same thing as a shape trace

[autumn pulsar]

capsule trace is a shape trace

[summer coral]

so perhaps do a capsule trace on the area and move it up or down till it finds a valid spot?

[autumn pulsar]

https://i.imgur.com/YGF9uJs.png

I trace to find a valid hit, and then I get the location from it and set the actor location

You can branch off the "return value" to check if you didn't hit a floor, or hit something you don't want like a kill plane and handle it differently

[summer coral]

interesting, i haven't ever seen that top bit of code before

[autumn pulsar]

oh, if you right click on an output, say the yellow one, you can do "split struct pin"

[summer coral]

yah, like a break but for a vector or rotation ect

[autumn pulsar]

it's a break but just built in

also you'd feed in the X and Y

[summer coral]

what is this nodes name

[autumn pulsar]

add

https://i.imgur.com/e7y7lKh.png

[summer coral]

im an idiot

[autumn pulsar]

https://i.imgur.com/9yC9jCW.png

[summer coral]

i was like 'thats a float add with some sort of offset' man i shouldn't code so late at night

[autumn pulsar]

well, that's what an add is

numbers make my brain melt

but eventually you get to a point where you stare at numbers you don't comprehend and find your issue

[summer coral]

what is your floor serch radius value? is that how far you want to look for an offset for

[autumn pulsar]

basically I take the goal object's location, add the floor search radius to the top and the bottom

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

Depending on how it works, you may only want to seek below

in which case you just subtract and skip the add

[summer coral]

gotcha, that is what i thought but i wanted to make sure, the value itself is just your goal zone

So im still getting a little jump when i try to set the location again, i thought it was due to the z being not accurate but it could be something else

in theory ive been set to the same spot ive moved to but the jump seems like that isn't the case

[flat jetty]

Hey everyone! Is Searching through Data Table is fast? Is it making linear search or some kind of binary search by sorting it before? I will have +400 items, and going to doing that often.

[frosty heron]

@flat jetty Data table is actually a map

in a map index is irrelevant, if you need indexes use array.

so in saying that, a look up with map is faster than an array.

[flat jetty]

Aha, thats good to know! Thank you.

[frosty heron]

Looping over large element in blueprint is brutal.

one of the easiest way to make things run faster is to avoid blueprint loop.

but if it actually matter or not the only correct answer is to profile it.

You need to measure your self, it's not a question for someone to answer.

but personally I will just move any loops for a large iteration in C++.

you pretty much pay for Blueprint overhead for every loop you do.

and ofc in some casses the difference can be 100x faster or more.

[flat jetty]

These elements are getting its DATA from that method i provided above, its only in the construct for now. But one thing i didnt understand is, if i change something in data, for example its offset, it wont affected immediately. I need to change scene or smth like that. What is the practiced way if we change something in a data asset, and immediately affect for the constructors?

[flat jetty]

Wow. Thats a lot. Why though? What **blueprint **can be doing that slow with for loop

[frosty heron]

Read Unreal engine myth buster article by Ari

[flat jetty]

Are there any tools like refresh immediately, so that i can see my changes for the constructors?

[frosty heron]

what constructor

Construction script is not constructor if that's what you are referring to.

[flat jetty]

For example, these canned foods are getting its data from the table's element data asset in the consturction script. And if I make change in data, like changing the offset, i cant see it immediately.

[frosty heron]

constructor runs before you even have a world.

[flat jetty]

I need to change scene or smth.

[frosty heron]

it sounds like you want to write the value to a Data Table or Data Asset

So anyway the way to run a function when you change a data is through PostEditPropertyChange

you cannot do this in blueprint, but I got example earlier for someone wanting to do the same thing.

#cpp message

[flat jetty]

No, i didnt give you enough context sorry. Lets assume we have a variable "Mesh". In Construction script, we set our blueprints mesh with that variable. But when I change that Mesh variable, i dont see immediate effect of changing it. And assume that mesh variable is inside the "data asset", and we reference data asset, instead of mesh variable,i change mesh variable's "assigned mesh" in data asset

I cant see immediate affect on my blueprint

[frosty heron]

English is not my native language, I don't completly understand what you are saying.
But if what you after is to do something when you change a property, e.g. typing a new characters for a string, or changing a static mesh value, or changing any value of any variable. Then the answer lies in PostEditPropertyChange. This is essentially the function that get called after you modify a variable.

[flat jetty]

So if i change scene, an return back, i can see them. But its a bit time consuming.

[flat jetty]

Hmm.

[frosty heron]

Hmmm I can change static mesh and see it updated just fine?

[flat jetty]

Yes, but after scene changing and returning back.
-- Construction script sets our mesh with a variable "Instance editable".
-- I change the variable.
-- Can't see immediate mesh change on my blueprint.

-- Scene switch..
-- My mesh changed.

[frosty heron]

oh ofc, you are just changing the variable

you are not actually changing the actual static mesh in the static mesh component

but yeah, I would point to the same answer if that's what you are after.

Construction script is not even a hack to me

it only runs when you hit compile or when you place the actor in the level.

If you want a function that runs everytime you edit your variable

PostEditProperty it is.

[flat jetty]

Hmm. Thats good to know actually. I can simply compile, or place some placeholders in scene to see changes.

Instead of changing scene and returning back.. 😄

[frosty heron]

I don't know if that will applies to actors that already placed in the level.

[frosty heron]

tldr, I have 1 line of code in construction scripts.

[flat jetty]

Thats what i am talking about, its getting data from data table in construction. If i edit "Data." I cant see it immediately. But like you said, its fine to compile and see changes.

[frosty heron]

it all comes down to when the consruction script is run and when the data is "ready"

as in if you already set the static mesh variable before the construction script is run.

[flat jetty]

Alright, that makes much more sense.

"Compiling" works just fine.

I can see now they are bigger when i hit compile.

[upper badger]

I have a camera set on a spring arm with collision disabled. It's a strategy game, so the camera is set way above everything and is just floating up there. Zooming in and out is controlled by the scroll wheel. When I hit play, the camera zooms out a bit, even though I didn't do anything with the scroll wheel. When I hit stop, the camera zooms out a bit more. And so on and so on. Any ideas on what's going on here?

[frosty heron]

no one will have a clue without looking at the code.

it could be you are interpolating to the zoom value and what unfold is at the start of the game, the current value is not of the zoom value so it tries to interpolate to the zoom value.

but then again, it's all just deduction. Try showing your work when asking question, it helps putting question in perspective.

[upper badger]

Here's my code for the zoom. Zoom min and max are just constant values.

[frosty heron]

and the interpolation?

surely you have that on tick

[upper badger]

yup, I forgot about that one.

[frosty heron]

so if you want to have 0 interpolation at the start, you want to make the value the same at the start.

maybe try BeginPlay -> Zoom Value = TargetArmLength

other than that, I don't have any idea.

[upper badger]

yea, it still keeps zooming out. thanks anyway :))

[flat jetty]

Hey everyone, I have a weird problem, My Pickup Item collision preset is set to PhysicsActor, and when i overlap with it, it prints OverlapAllDynamic. What might cause that?

"Get Collision Profile name" prints OverlapAllDynamic.

[frosty heron]

append the string with the component name.

make sure you actually printing the target component instead of some other component.

[flat jetty]

Yes. It was the Sphere Component.. I found it. But after i remove it, i can no longer trace with my mesh. My mesh has already collision. But cant seem to interact with it, even if it has phyiscs actor now.

Its not even logging profile name now

[frosty heron]

did you generate overlap on the physic assets?

open the physic assets, select the bodies, make sure it generate overlap events.

[flat jetty]

I check like this, tracing for objects.

Get Actors to Ignore has only attached actors

And this is object types to trace

Now i can see it has no Physics body..

😄

[surreal peak]

Do you still have a problem or is it now resolved?

[tropic token]

Hey guys, I have an actor in the world, when I double click in in object browser focus is being shifted to it. is there any way to control transform of this focus?

[frosty heron]

Just wondering if it's really important.

If I have to tap engine code for that then no ty.

[bleak moon]

again hope its not against server rules but gonna plug this again, if commenting on the doc is easier than commenting here then please feel free 🙂

[tropic token]

it's nice to have for specific things in level design. sometimes it's a bit off

[dark drum]

What do you mean by control the transform of the focus? As in where it moves to when focusing an object?

[tropic token]

yep

would be great to override it for specific actors

[flat jetty]

It is.

[frosty heron]

100% not in blueprint for those kind of function. Better luck in other channel.

[flat jetty]

This is my base class BP_ItemBase, i implement ItemTag, and quantity.

• And I have created a child class BP_PickupItem inherited from it.
• Set the Item tag in there to Item.RawMaterials.Food
• Then inside my interaction script,
  I call that data, and print Item Tag.. which prints as NONE.

What might cause to that? I already tried to fill PickUpItem's Get Interactable Data which is my child class.

And its is default category idk why, and its not yellow

[frosty heron]

What is this? You setting closest intractable to none then try to call a method inside a null object?

[flat jetty]

Yes... Actually right. I thought i was setting input object..

Found out wit those.. Never printing..

[crude pike]

perhaps this question might be better suited for #editor-scripting but i guess it might apply to this channel? anyways :

I have a LevelInstanceActor in my current scene and am trying to change which level file is assigned to it. I don't need to do the change at runtime or anything, it's just a map assembly script for the editor.

I'm using the "Set World Asset" node to do this, but the input is a "World Asset" variable.

The way that my BP works is that I give it an asset path as a string, not a direct reference. With other variable types I can convert the asset path to a SoftObjectReference and then load the asset, but I'm struggling to then convert it to a World Asset that can be plugged into the "Set World Asset" node... Any ways around this?

[dusky cobalt]

Async Load Asset and then cast to World Asset ?

[merry lotus]

Hey guys, I need some help with this game I'm working on. For some reason the "on component begin overlap" function is working fine when I manually place the actor in the scene. But if the actor is placed by a "spawn actor from class" node. The box collider just doesn't work

[frosty heron]

it is probably the same case like when you place 2 actors in the level next to each other and check their overlap.

perhaps OnBeginOverlap only works when two components collided. Not when they are already colliding from spawn.

So on BeginPlay you probably want to use IsOverlappingActor and use that instead for your BeginPlay overlap.

[merry lotus]

Ohh alright, thanks. Let me try that

[frosty heron]

try casting

[merry lotus]

Unfortunately it doesn't work

Like

The overlap doesn't even register for any object

a simple blueprint like this won't even work

[frosty heron]

and the code?

[frosty heron]

This got nothing to do with what I suggested earlier though.

[merry lotus]

This is the overlap code (for now)

[frosty heron]

as stated BeginOverlap only works when the 2 component not already collided.

If you want to check on Spawn, BeginPlay -> IsOverlappingActor

[kind estuary]

Which node should i use here? Those 2 below say they are COSMETIC 💅

COSMETIC

what is cosmetic

[frosty heron]

Are you doing multiplayer? @kind estuary

[merry lotus]

Alright let me try

[kind estuary]

not for now. maybe in 10 years yes

[frosty heron]

Then even get player controller 0 will work.

as every single widget is owned by the local player

[kind estuary]

okay but what is the most appropriate to do here

yeah

[frosty heron]

depending on the context? for single player owner of a widget doesn't mean much.

after all you are just displaying widget to the one and only player.

[merry lotus]

Do you mean this?

[kind estuary]

what if it was multi ?

[frosty heron]

Yeah but you probably want to check in the BeginPlay of the Actor you are spawning.

[merry lotus]

This code is actually connected to begin play

[frosty heron]

I don't think you are reading what I said X_X

[merry lotus]

I am

[frosty heron]

So I can only re-iterate then

[merry lotus]

I'm moving the check to the actor that I'm spawing

[frosty heron]

in the beginplay of the Actor you are SPAWNING

this actor here

[frosty heron]

Actually doesn't even matter even in multi.

[merry lotus]

Okay, so I did this in the actor that is spawning.....so would something like this work?

[merry lotus]

Yes I did that in that specific actor

[frosty heron]

You have to provide object to test the overlapping againts

at the moment the other is left empty

[merry lotus]

So I put my main pawn

[frosty heron]

that will check againts your player pawn yeah

try it.

[merry lotus]

Alright

[merry lotus]

But this works when I place the actor in the level manually.....why not if I spawn it with blueprints?

[frosty heron]

Not when they are placed in a way that they already overlapping in editor.

already stated the reason, OnBeginComponentOverlap only works when the objects are not already overlapping.

[merry lotus]

I see.....

[merry lotus]

Yeah this doesn't work.......

[frosty heron]

tldr that event is only reliable if the components are not overlapping when they are spawned

[merry lotus]

Hmm okay......

would it work if I spawned it in a location with no other actors

then instantly moved it to the desired location?

[frosty heron]

I don't know but I would expect a game Im playing to be able to address such simple situation....

if im spawning where the powerup is and i don't consume it, that won't be a nice experience.

[merry lotus]

Yeah

thats actually whats happening XD

Anyways

thanks for the help

and I'm sorry I don't understand easy 😅

[frosty heron]

we all gotta learn somewhere, if the code didn't work, you might have to debug and check if the cast succseed

and if the overlap actually work. (collision channels, etc)

[merry lotus]

Hmm okay

thanks

[frosty heron]

@merry lotus im testing an example now

works as expected.

actually with spawn even OnComponentBegin overlap work

I think the BeginPlay is to address actors that is already placed in the level.

But for spawning, it work just fine.

Im just spawning the powerup where the player is atm.

you can check the orange text and the potion that get spawned where the character is

collision settings for the box component

[dusky cobalt]

I'm pretty sure there is something in C++ that can update overlap actors on the spawn, but it's not exposed to blueprints.
One way is to change this to Sphere Trace By Channel/Objects and just use it on tick/timer by event.

Hacky way is to Set Actor Location to anything else like 15000 15000, and then back to where it should be (probably better to do it with the static objects than with the one you control/move). This should retrigger the overlap. @merry lotus

[frosty heron]

Actually on spawn the OnComponentBeginOverlap work just fine.

I tested it above.

[dusky cobalt]

but you need to make this logic on begin play to get overlapping actors, yes?

[frosty heron]

perhaps for overlapping actors on design time

but he wants it on spawn then no issue with OnbeginOverlap

I wouldn't do something like teleporting the player some distance away and back. That should not be an option imo.

[dusky cobalt]

yeah definitely make sense

[merry sparrow]

Hey any one know a tutorial or any guide for making a username password menu for a level so it can save user data also user need to register/ sign up i made a normal one with out api but i need to make sure its getting url from an api and opens it !

[frosty heron]

depending on how elaborate your log on system you want it to be.

if you just want me to throw a tutorial I can recommend then Stepehn Ulbardi dedicated server.

but it's not a blueprint only tutorial.

you kinda required to do some coding either way if you want to interact with data bases

[merry sparrow]

ye i know about that i was trying so hard on blue print only

[frosty heron]

some task are impossible in bp. It is what it is.

[merry sparrow]

also tried chat gpt and deep not helpful at all

[frosty heron]

you can only use what's exposed to you

[merry sparrow]

i will watch this tutorial to see what i am getting out of it thanks for shearing 😃

by the way where do i find this tutorial i cant find it on google

[frosty heron]

Sure, tldr. You get to interact with data bases, setup dedicated server, setup Login system, interact with your data base to store player's data / progress. Etc.

[knotty flare]

Hi Mahdi! If you'd like to push for a blueprint solution - I would recommend looking into Epic Online Services & consider the 'EOS Integration Kit' plugin from the nice folks at BeTide! They have an amazing Discord for support & their product works well from what I've seen so far (haven't shipped yet, but integration is going well)

[frosty heron]

What's Epic online service got anything to do with log in system, curious.

[knotty flare]

Well, if you want a purely custom database and 100% controlled environment, it's maybe not the simplest way - but it offers per-platform sign in and easy player data storage

Just proposing in case that fits the need and help simplify the process 🙂

[frosty heron]

no idea about EOS or it's capability so no comment from me. But imho you will end up knowing how to code either way. Not something that you should pursue using BP only.

[merry sparrow]

i do have a programer friend will work on api and make a new data base it self new api also

i just need to find a way to connect to that and call it thats all

[frosty heron]

if you don't need any serverless functionality then just make an HTTP request call

[merry sparrow]

ye thats what i am about to do thanks for helping i will try to get into http request call and see what happens

🙌

[storm solar]

When i have a list view widget. I want to select a widget and "Lock in" the picked widget. That will disable movement of that widget list, but still keep it focused. How do I do that?
i.e: When I use the arrow keys to select potion and press enter, I dont want the arrow keys to effect the item list, but still use them for a diffrent input, like selecting target.

[flat jetty]

How can i see "the starred" nodes in here? For example i starred "Add Custom Event". But icouldnt find a way to find favorites.

[autumn pulsar]

Does Enhanced Input have a Key Released Option?

*Exec out

[proud pilot]

Hi everyone !
I have a question, because I can't find solution in web neither yt. I have problem with my project. If is possible to delete assets ? I think about node, because I can add node "Get Assets by path" and "Duplicate Assets" but I can't find "Delete assets". I need delete "Data Asset" which I created of node "Duplicate Asset". I want create at runtime ? If is possible make this in blueprint or only in C++ ?

"Data Asset" are created at runtime, but I need to delete them at runtime as well. Is it possible ?

[surreal peak]

Hm. Check if the top left menus of the blueprint (window, view, edit and what they are all called) has an option for a Palette.

That might result in a sidebar on the right with the starred nodes

Might also be called differently

[surreal peak]

You'd add a Pressed and Released Trigger. Change the Value to Boolean and branch with it on Triggered.

It'll be true on Pressed and false on Released

[surreal peak]

Could be that if you simply ensure that nothing is referencing the asset, it will be GCd automatically

Are you sure the duplicate asset stuff even works outside the Editor?

This sounds a lot like this is editor only stuff.

It's not that common to duplicate assets runtime. If I ever did that then only to generic UObjects in c++

[autumn pulsar]

How do I use this node? When I try to add the blueprint interface it's not on the list of available ones https://i.imgur.com/ALarJ5e.png

is it a C++ interface only?

[surreal peak]

Could be that the methods are only virtual and BlueprintCallable but not implementable for Blueprints.

If you can read c++ then open the header of it and check

[autumn pulsar]

https://i.imgur.com/5Lib3i7.png

rip

[surreal peak]

Well or that

You could just make your own if you aren't using GAS anyway

[autumn pulsar]

Might do that

I don't want to drop to C++ unless I absolutely have to

Maybe I'll just make it an actor component instead of an interface

[surreal peak]

You'd still want an interface to get the component without having to search through all components

[autumn pulsar]

Could just have other components register with the tag manager component

making interfaces for every component sounds like a lot of work

[narrow sentinel]

So i have an issue where getting the elasped time that a timer has ran for on tick seems to not work and I can see it gets to about 0.16 roughly then starts from 0 again

I've checked and I'm not calling the timer over and over

[storm solar]

Any idea on this issue?

[flat jetty]

Guys, I am bugged so bad.

I have some items in my stash, and when i click restore, This is the only its coming to push. ANd its coming and coming. I cant get others, i push and it comes again. What should I do?!

I hate github desktop in Unreal Engine.. I cant even see what s going on especially with Git LFS, when LKAJSD12380917321.files appear.

Now my Interaction component disappeared?!

[dusky cobalt]

Are you implementing interface for every component usually. Like do you avoid Get Component by Class, you just call Get X Component interface?
Do you have like 1 interface for every component, or every component has own interface for that?

[gusty shuttle]

Question: Is there a more efficient way to load in soft references than this?

[surreal peak]

I honestly rarely have components attach to random actors.

But if I would have that I would have an Interface for it, yes

[surreal peak]

In what way?

[dusky cobalt]

Random actors? so do you mean by that, that you have interface for that component anyway so it's not like a problem that you have create it just ''to get component'' ?

[surreal peak]

No. "Random Actor" as in not having a common class to cast to.

[gusty shuttle]

I'm trying to use Data Assets to load in different body parts to my metahuman. I have struct with all the data assets within, and I'd like to change body parts based on which index is selected for the struct. Loading up these soft references would make for a large graph, im asking to see if there's other ways to load in soft references other than casting to each specific part

[surreal peak]

E.g. if you have an Inventory Component that can be on a Character and a Chest Actor, then I would have an interface to generally retrieve it

[surreal peak]

Do you load all of the soft references in a given DataAsset or only parts?

[gusty shuttle]

Only the parts

[surreal peak]

I mean, in theory you wouldn't make things soft references if the thing they are in can already be one

+- for editor load time, but then you'd potentially load all the inner ones when the outer one is loaded.

In C++ you can load multiple at once too.

[dusky cobalt]

and it would be Component's interface right? so for each component you would have new interface, kind of.
And by ''common'' class. It's situation where you can Cast and get Component directly, instead of Get Component by Class.
Generally, do you mean that it's good practice to avoid Get Component By Class and either use interface, or first cast to the base class that will have that component avaliable?

[surreal peak]

Yeah. But you make it sound like you'd end up with 20 interfaces. You rarely run into the situation. A lot of components are only used on one base class.

[dusky cobalt]

I didn't want to sound like that, it was more to understand it correctly. Got it. Yes it makes total sense.

[surreal peak]

The get comp by class is just not as cheap as just casting and getting it (which an interface also counts as)

It's more like a fallback that exists if you have no other way

Like if you work with some actor and you can't add any interface to it but you still want a component for class box collision in case it has it

[dusky cobalt]

That is very good point and I'm asking because Im at the time of refining some components and I was using FunctionLibrary to get components with Get Component by Class but I'm just gonna create nice interfaces for them. Much better.

[surreal peak]

Which happens more often if you do some editor tooling where you have to work with whatever actor pointer you get

[surreal peak]

Yeah FunctionLibs in Blueprints are also a bit of a pitfall if you aren't careful.

If you reference a lot of Blueprint classes in it and you then use that function library in BP A it will cause the other classes to also be loaded

Which can cause quite the nice reference chain and long editor load times

[dusky cobalt]

I have them in C++ actually, is it also similiar problem? or it's only with blueprints?

[surreal peak]

No only BP

[dusky cobalt]

Ok, thanks!

[harsh notch]

Hello! Does anyone know how to disable push away ai from player on collision? Tried to disable "Simulate physics" on AI Character and Player capcule component and mesh, tried to change physics interaction in character movement component but it didnt help too.

[flat jetty]

What's best version control you have used for Unreal Engine? Do you recommend Perforce? I thought its paid app. I have many troubles while working with friend in Github Desktop, for example while pulling, there are coming existing stuffs, and then removing it automatically IDK why?! I have ben using Github & Desktop in Unity, never encountered stuffs like that. I think it works kinda weird in UE.
Whats the workflow for pull/push in UE for Github? Should i close the project for example etc.

[surreal peak]

#source-control ?

[faint pasture]

I really like Plastic SCM / Unity DevOps, but it seems like I'm the only one lol

Dirt cheap, fast, works great IMO

[surreal peak]

Yeeeeah, Plastic is one of the last ones I would touch

Self hosted GitLab or Perforce, depending on team size, works wonders.

But let's keep it to #source-control

[autumn pulsar]

Is it a bad idea to have a lot of actor components on an actor?

or is it better to combine stuff

[stone umbra]

why does my rock hit the ground before launching?

super new to unreal n im pretty stuck on this

[runic terrace]

There doesn't seem to be an issue here

What happens exactly?

[static tide]

I need to change voice pitch in voip. i need sourceEffectPreset which is able to change voice pitch, anyone know its name?

[stable nymph]

I have a question for those of you who make blueprints with tons of options: what do you do to make your blueprint navigatable? With each variable taking up an equal amount of space, it quickly makes 20 variables feel like scrolling through pages (especially with arrays). I am debating using editor widgets to create sub menus where each category has a button that can change the context of the menu. There is also scriptable tools but that seems like it may be overkill for the extra control. Curious what you all do to get around this

[runic terrace]

Check your mesh collisions

Only the capsule should collide with the other character

[runic terrace]

You can organize variables into categories

[dusky cobalt]

When I started hard prototyping I put everything into one class, monolithic way to make things, the blueprint was dirty, it was working though. Then I made 1 thing to component, now 99% of things is components and the base class is almost empty (just some really small individual logic is there). For me it's much better to organize and then.. possibility of reusing existing component instead of thinking how to merge classes when suddenly you realize that 2 different classes could use of the same methods. I would say put everything in components and it's probably not much different having: 1 class with 2000 lines of code, or 20 classes each with 100 lines of code. Literally doesn't matter in this context. It's more how you organize code and you know, oh if I want to edit health I just edit it there, everything will still work, everyone will ''get'' the change.

Composition is more popular these days because of how reusable things are. Just make kind of sure each component does one thing (with micro exceptions maybe), if you describe component that it does this AND that, then it probably should be 2 components.
Also there is nothing wrong with components communicating with each other. It just shouldn't be coupled so much that they will break when you delete one (obviously you will lose function of the one that was deleted, but the other one still should do it's job, even though there is no one that listens to it anymore (kind of)).

[dusky cobalt]

Well, kind of coincidence you ask about it, but if you split some parts of code in components, it doesn't get that dirty with 50 variables because of 4 different ''systems'' inside 1 class.

[high gale]

I am making a security camera that whenever it spots the player, it alerts all enemies within a certain range. My original idea was for it to cast a sphere trace to find all the enemies but it seems that sphere traces don't register pawns into their hit results.

So I am kind of lost on how to move forward with this idea

[runic terrace]

A single sphere trace will just return a single actor, and it might just return a wall it hit

Maybe use a sphere overlap instead?

Or multi sphere trace

[high gale]

but would that affect pawns? because it says on the hit result it lists "actors" and not pawns

[runic terrace]

Pawns are also actors

Anything that has a transform in the level is an actor

[high gale]

so even the static wall with no code whatsoever?

is an actor?

[runic terrace]

Yes

[high gale]

oh

[surreal peak]

It's a StaticMeshActor :P

[drowsy gorge]

Hello

I am going insane.

I have an actor component MeleeFighter. This component is added to the character.
In this component there is an Actor Object Variable called CurrentWeapon. When character picks up a weapon, this is set to that weapon actor, otherwise it is Nil.

There is a function called "ChooseAttackMontage", that picks the attack montage the character should use, based on whether they are holding a weapon or not (So if holding a sword, choose a sword attack montage, otherwise choose a punching montage).
The logic is like this:
If CurrentWeapon IsValid -> SwordMontage,
Else, PunchMontage

The problem:
When the Player Character picks up a weapon, the AI Characters for some reason start to think their current weapon is valid too.

What's even weirder, for debugging, if on tick I print the CurrentWeapon validity, all of the AI Characters correctly print that their weapon is invalid.
But printing just inside that ChooseAttackMontage function, they all think that it's Valid.

There is only one place where I use Set CurrentWeapon, and I added a print string there as well. It is only set once, for the player, so again, seems to be correct.

So WHY IN THE HELL does ChooseAttackMontage function think that CurrentWeapon is valid, if everywhere else it is confirmed Invalid?

All of this logic is inside the MeleeFighter component.

The tick validity check, and Weapon Set, confirm that the weapon is correctly Invalid.

But only inside the ChooseAttackMontage function, it for some reason prints WeaponIsValid

[runic terrace]

Are you absolutely sure it's the AIs that are printing ''valid'' on the function and you're not seeing only the player's prints?

Do they print ''invalid'' if it's invalid inside the function? Or do they print nothing at all

[drowsy gorge]

Absolutely sure it is the AIs.

The ChooseAttackMontage function is only called when they are attacking. I can visually see the AI playing the incorrect attack animation when that WeaponisValid prints.

[drowsy gorge]

I just added print Invalid inside the ChooseAttackMontage function. It never prints. Because for some reason only inside that function, it thinks the Weapon is valid

[stable nymph]

I do have variables into categories but it still seems like a pain to keep opening and collapsing different options to get to the spot you want. Each category I made has at least 20 variables and some of them are arrays that open into dozens more lines. Creating more subcategories has diminishing returns

[drowsy gorge]

Wait no

[stable nymph]

That is an interesting approach

I'll look into it, thanks

[drowsy gorge]

I just added a print string GetOwner -> GetDisplayName inside that function, it is printing the PlayerCharacter for some reason.

Let me check why

[runic terrace]

Your AI might be calling the function on the player instead of their own actor

[drowsy gorge]

Hardest facepalm in my recent life

I have no idea why would I call this function on the Enemy

Anyway, thanks for helping find it!

[runic terrace]

lol, you probably put that there as the enemy of the player which is the ai

but it's vice versa

[autumn pulsar]

Is there a way to set which camera the player controller uses?

[runic terrace]

If cameras are in different actors use Set View Target

If in the same actor it uses whichever camera is active

[autumn pulsar]

I was trying to spawn a camera on a player object instead of attaching it

and it wasn't immediately inheriting it

[runic terrace]

Deactivate the previous camera if there is any, then set the new camera active

If it doesn't work maybe also call Set View Target on the actor

[stone umbra]

srry for late response

[runic terrace]

Are you detaching the rock right before you launch it?

Does it attach to the player?

[stone umbra]

yea its attached to the player, like it moves with the player when the player move

[runic terrace]

Where and how do you detach it?

[autumn pulsar]

Are cameras expensive to have if they're not being used?

[runic terrace]

No

[autumn pulsar]

Wondering if it's even worth it to try to spawn it instead of just not using any camera logic when it's not controlled by a player

[stone umbra]

is this what you mean

i can show the whole thing but its pretty big not sure it will fit in one screenshot

[runic terrace]

Are you not detaching the rock before you launch it?

It's either that creates some weird interactions, or something with your camera transform

Are you viewing playing as client or the server?

[autumn pulsar]

that logic is so messy

if you double click on a line you can create a redirect node

so much more useful for creating clean flowing logic

[runic terrace]

Also can press q to align two nodes

[stone umbra]

yea i really need to start over from scratch im so confused with unreal

[stone umbra]

im not sure tbh

[autumn pulsar]

game dev is hard

[stone umbra]

yea thanks anyway @runic terrace

[runic terrace]

Starting from scratch isn't a bad thing when you're new to game dev

[autumn pulsar]

but I would detach it in the same function that you launch it

[runic terrace]

imo it's the best thing to do when learning

[stone umbra]

what are some really good sources for learning?

just youtube tuts?

[autumn pulsar]

https://i.imgur.com/ooFdb2i.png

[autumn pulsar]

Youtube tuts are really hit or miss. The annoying thing is when you're learning you don't know how to avoid the bad ones

[runic terrace]

There are a lot of tutorials on Youtube that promote bad practices, it's not easy to differentiate the good ones when you're new
There are courses on Udemy and stuff but Youtube isn't a bad source as long as you take the info with a grain of salt

[autumn pulsar]

This is a bit of a Rabbit Trail, but if you're serious about this whole game dev thing, I'd take some time and learn a bit of C++

Blueprint is heavily derived from a lot of concepts based on it

and knowing a bit makes it easier when you need to drop down and do things in C++

[runic terrace]

C++ might be a bit heavy if they don't have prior programming experience

[stone umbra]

blueprints are already cooking me enough haha

[autumn pulsar]

was my first language

[runic terrace]

Something like Python would be better to get a grasp of coding

The same programming principles apply to C++ anyway

[stone umbra]

it just doesnt seem like there is a correct way to learn unreal most people i meet say they learn from youtube but like you guys say there's a bunch of bad practices on youtube as well

[runic terrace]

Or even C# tbh, I started with unity to game dev and it's way more intuitive than Unreal's C++

[autumn pulsar]

Some of it is just stewing until it makes sense to you

[runic terrace]

Yes exactly, there isn't a set in stone correct way

[autumn pulsar]

There's no "correct" way because everyone is different

[stone umbra]

any specific udemy course you guys can suggest

[autumn pulsar]

and approaches change based on what you're doing

[spring magnet]

any updates on this? 👀

[autumn pulsar]

But a vague answer like that isn't very helpful to you now is it

[runic terrace]

Tbh as long as you invest time on learning it doesn't matter how you do it

You eventually learn

[stone umbra]

yea that makes sense but i don't know what any of the blueprint stuff really do tbh especially when i'm just following a tut and i feel like i need to really learn unreal before i start doing my own thing idk im a complete beginner

[autumn pulsar]

Coding is an adventure, and a long one too. It's hard to find anythiing comprehensive that you don't pay for

[stone umbra]

yeaa thats the thing im willing to pay atp haha

[autumn pulsar]

A large part of it, is having a curious mind

and simply trying things out

[stone umbra]

shill me a udemy course lmao

[autumn pulsar]

And that's something that paying isn't necessarily going to help you with

[stone umbra]

true

but i need something structured for sure

like a curriculum

[runic terrace]

Udemy courses tend to be very specialized though, I'd probably take more time on Youtube before doing courses. You learn best when you're experimenting with just throwing rocks at a wall to see what sticks

[autumn pulsar]

I don't know of any Unreal Specific though

Honestly, if you watch a wide variety of YT videos, you'll eventually get the gist of what sucks and what doesn't

There's a sliding scale of "Easy to set up" vs "Comprehensive solution"

A lot of "Here's how to do it in 5 minutes" tutorials kind of suck because they don't take any expandability in mind

[stone umbra]

yea exactly i dont really feel like i learn anything from these types of tuts

but thanks guys i appreciate your time and your advice

[autumn pulsar]

I think just getting used to reading the nodes isn't a bad thing

You could also ask here to explain the logic if you just don't understand

[stone umbra]

oh yea you'll def see me in here more often

[autumn pulsar]

Games do require an understanding of a few math concepts such as vectors

https://i.imgur.com/Y9F0Cfr.png

[faint pasture]

That's why I advocate what I did. Just learn enough of the basics to get going and go

look up specifics when you get stuck, but don't go following along painting by numbers

[autumn pulsar]

Painting by numbers is fine, as long as you dissect it

"Oh hey they did something interesting here, why did they do that"

[runic terrace]

I lost count on how many projects I abandoned and made from scratch over and over when learning
I probably made the same inventory system for like over 100 times trying to do it better each time until something clicked

[autumn pulsar]

Don't be afraid to make projects with no intention of completion

Like learning how to make AI with a complicated project is probably a bad idea lol

whereas a tiny stealth game with no real gameplay is great practice

[runic terrace]

Yeah I used to open projects just to make a single mechanic

Because a game is simply a mix of multiple mechanics under the hood

After some time you reach a point you don't need to look up tutorials for a new mechanic you haven't done before

[autumn pulsar]

Could be like me making my own shitty version of GAS

[runic terrace]

^ Exactly, to be honest I still prefer my own shitty version of gas lmao

There's something special about building the entire system by yourself

[autumn pulsar]

for sure

[runic terrace]

Not the wisest thing but it's fun

[autumn pulsar]

teaches you a lot to reinvent the wheel

[faint pasture]

Also it makes it easy to actually understand everything going on

[autumn pulsar]

Does the controller get added to the actor after the construction script?

[runic terrace]

Construction script runs first before the controller possesses it

[autumn pulsar]

hm

was wanting to do things depending on if it's a player pawn or an npc pawn

[frosty heron]

Just jump to c# or cpp if they gonne learn unreal. Cpp being my first language doesn't make learning python enjoyable. Just pick strong typed language.

[autumn pulsar]

C++ is great because you can make Data races so only the fittest threads get to use your variables

[frosty heron]

Other than pointer which is gonna be necessary, the basic ain't that bad.

[autumn pulsar]

Undefined behaviour is just suprise mechanics for your game

https://www.learncpp.com/

also goated website

[frosty heron]

Learn OOP until you can read code which made you not having to learn blueprint.

Afterwards fly on your own and look at project examples for ideas or reference.

Eventually you want to get out from tutorial he'll

But yes you don't know what you don't know so don't be obsessed with inventing your own wheel for everything. Take inspiritation from other people system or code.

[flat jetty]

Hey guys, I drop my items from inventory with DragCancelled event, But for now, I spawn the item in front of the player, and apply force in player's forward direction. But instead, I want to be able to Get mouse position, and add impulse there. Here is what I tried.

-- On Cancelled Event, I get mouse position / DPI from player controller, then convert it to world space.
-- Then I substract my player position from that world space and normalize it, then multiply with float for strength.,
-- And apply impulse to that direction.. But it seems like it doesnt work, going same direction as always. Also printed mouse position, and its almost same everytime.

[frosty heron]

There should be a pure node that says deproject screen to world

[flat jetty]

What should I "exactly" pass to Screen Position? PlayerController.Get Screen Mouse Position?

[autumn pulsar]

Specifically for games, I think the most important general programming concepts are:
-Shallow Vs Deep Copies
-Pointers and References
-Classes and Functions
-Fundamental Data Types
-Arrays and Maps
-Structs

Then Blueprint Specific:
-Actor Components
-Interfaces and when to properly use them
-Tick and what and when to put in
-Binding Function Calls

Gameplay Math Specific:
-Traces and how to use them
-Vectors, Transforms, Rotators and how to get what you need from them
-Lerp and how to use it
-General Physics knowledge isn't required, but helps a lot especially for more action games

[flat jetty]

Or can I get the mouse position from DragCancelled event?

Smth. like that.

[autumn pulsar]

I'd run it in the tick and print the outputs and see what it's giving you

[frosty heron]

Actually convert screen to world should work, what is your code like?

[flat jetty]

Here is how I add impulse, If i just apply from forward with scaled value, It works as intended. But this is always going the same direction.

Wherever I look.

Drop Position is the value we set above from Deproject

[autumn pulsar]

just use the drop position vector

also use world direction

unless I'm misunderstanding what you want

[flat jetty]

I spawn my item in player, then add force to the mouse position

which is (mousePosWorld - playerPos).normalized

I call AddImpulse inside the Update Physics method

[autumn pulsar]

You shouldn't need to use the player position because it's camera normalized

[frosty heron]

You have to add the result of the multiplication with the actor location.

I think.

That looks incomplete.

[flat jetty]

But If I do that, it works as intended, pushing towards the item from playert

[frosty heron]

Ofc but they not the same?

[autumn pulsar]

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

Are you wanting this or this?

assuming you're dropping at the center of the screen

[flat jetty]

In last picture, I push the item in the forward direction, What I wanted is, push towards the mouse position, which is the mousePosWorld - playerPos, normalized.

[flat jetty]

Seems like it. My brain stopped. I worked 13 hours today in this project. 😄

What am I missing?

[frosty heron]

You subtract location so you get direction then you normalise it to one unit. Then you multiply it back by 300. That should give you a direction from the world origin. If you want to start from the player, add the result to the actor location.

This is assuming drag position is already the correct value.

[autumn pulsar]

Like, if I drop the item on the left side of the screen, do you want it to go to the camera's left side, or the actor's left side?

[flat jetty]

Here is I simulate dropping, Red Arrow is where i want to add impulse

[autumn pulsar]

So you want it to be thrown at the surface where the cursor is overlapping?

[flat jetty]

Red arrow is the where I dropped, green arrow where it went

[flat jetty]

Yeah, that might be. I thought Deprojecting mousePos would give me that value

since my mouse is currently there :/

[frosty heron]

It does. Your math is off

[flat jetty]

Also tried this like you said, am i missing smth?

[autumn pulsar]

I can think of a lot of solutions, I'm just having a hard time understanding what you're trying to accomplish

What result do you want from a top-down perspective?

are you able to draw?

[flat jetty]

Lets look at from top, when I drop my item, I want to spawn that item in my player's front, (which i already accomplished), and add force to that green direction,
The green icon is where I drop my item as you see

[flat jetty]

Here is I added my actor location with multiplied value

[frosty heron]

And the behaviour?

[flat jetty]

So the direction is here simply (mousePositionWorld - playerPos).normalized

[frosty heron]

I would try to do debug by spawning an actor in your drag points location.

[flat jetty]

You are right, let me debug this more

[frosty heron]

Could be dpi or something blocking that alter the end point. No idea.

[autumn pulsar]

https://i.imgur.com/9BwCZlV.png

I think this will give you what you want

[frosty heron]

The end trace not right i think.

That will start from the world origin you need a reference location.
Which should be the camera loc

[flat jetty]

I think thats something to do with mouse position result, I will debug it, Since its 3D world

Anyway, for today, I will leave it as player forward. I am really tired. 😄
Thanks for helping me guys. ❤️

[autumn pulsar]

I was assuming world position was from the camera viewport

[frosty heron]

Yeah that should be it but regardless you still need to account for that in the end trace.

[autumn pulsar]

You can copy paste this into your graph

[flat jetty]

I think that would be also enough

[autumn pulsar]

oh I forgot an add

[frosty heron]

I would check if the circle blocks the trace...

Something to watch out for.

[flat jetty]

Sure, thanks for reminding me

[frosty heron]

For sanity check turn off collision on your components imo.

[flat jetty]

Thank you guys

[autumn pulsar]

Can also add a new trace channel if needed

[flat jetty]

What do you mean by that? Which components

[frosty heron]

What ever that may block the trace e..g if you have any component in the actor like a sphere collision etc.

Obviously don't touch the capsule collision

[flat jetty]

Aha, Understood.

Now tomorrow will be replication phase..

[autumn pulsar]

UE Clipboard is so great. You can paste this into your level

[harsh notch]

Thank you, it was a problem!

[flat jetty]

Would we still need to fill mouse position for deproject?

[autumn pulsar]

yeah

What this does is it takes the mouse position from the camera, then fires a trace into the world using it, seeing if we hit something, get the location of the impact, get the actor location and create a vector from the actor to the location, normalizes it, then uses it as the throwing vector for the actor

you may also just use an offset of the actor for the Z direction

so you get a nice toss every time

[flat jetty]

So this node takes player location right? Some of tem was missing

[autumn pulsar]

yeah

assuming this is in the actor blueprint

otherwise you'll need to get a ref to your player actor

[faint pasture]

That node will get the location of self, whatever self is

if self is your players pawn then yes

[grim timber]

does anyone know how world vector for Add Input Vector are floats here? https://d3kjluh73b9h9o.cloudfront.net/original/4X/a/0/8/a081d710215af943be60ef5dc4d1e22d532c91a0.png

Right click the vector and split pin

And to go back right click and combine or whatever it's called

AH thats it. I promoted to variable, didnt even see the split. tysm!

Split pin my beloved

Do event dispatchers have a certain time limit to send during, or are they forever once called?

[stuck sparrow]

Hey all. working on a VR project where I am creating a sort of "ammo pouch" like effect, where a player can grip and spawn an actor that goes into their hand. I got this to work, however on Index controllers even slightly grazing the grip button causes the thing to spawn, which is not what I want. Ive tried a bunch of different solutions that didnt help... I tried setting a deadzone on the axis mapping, creating seperate axis mappings for grip force to compare against.. nothing is working. Either the thing wont spawn, or after I let go of grip it gets stuck to my hand forcing me to re grip, which I dont want either. Has anyone come up with a good solution to this problem?

[grim timber]

can you explain from a gameplay perspective what is supposed to happen (not including blueprints)?

[grim timber]

so you're concerned about the time it takes a event dispatch to work?

[grim timber]

https://www.reddit.com/r/unrealengine/comments/1dt5t77/using_tick_or_event_dispatcher/

https://www.youtube.com/watch?v=r20VEPH_e0o

seems like event dispatch is stable so... forever unless you do something that breaks it

[frosty heron]

Forever what?

Time limit?

How hard would it be to export LYRA character with abilities, to some new project? 😂

[frosty heron]

general advice is just to take what you need.

Lyra is over enginereed to be grabbed as a whole from testimonies of those that have touched it.

[surreal peak]

Lyra Character is probably too heavily integrated into lots of other stuff to easily migrate it

[dusty mountain]

Evening, gents. Trying to follow this simple code snippet in these two pictures yet can't seem to get the [Set Gravity Direction] node he shows. Anyone got any idea why I can't access the [Set Gravity Direction] node from my [Character Movement] component as seen in his pix? https://imgur.com/a/walking-on-planetoid-PNPgcpJ

Hecks, it's even greyed out in my Character Movement... I must not have an option enabled somewhere...

[surreal peak]

Quality of that screenshot is really low.

Ah, it's just the preview. nvm

Can you show where/how you are trying to access the node? The variable being greyed out doesn't mean much

[dusty mountain]

Found it: Set Gravity Direction is only available on 5.4 up. Project was on 5.3

[tranquil lagoon]

I'm sure I am doing something wrong, but for some reason when trying to get the velocity of my pawn with a FloatingPawnMovement component, the velocity (instead of being a constant 60) is erratic and jumping all over the place. Ticking off "Simulate Physics" fixes this, but also then the pawn floats and thats not what I want.

I have changed nothing besides what is displayed in the picture. What could cause this?

[tired hollow]

Yes

I was wondering if it had a time limit

[frosty heron]

no

[flat jetty]

How can I get "parent:beginplay here?

Here it is.

What is the best way of toggling those with button? I can simply use Flip Flop, but since my game is FPS, I set InputMode to UI only, which is disabling my Inventory input. What is the good way of doing that

[frosty heron]

FlipFlop 🙅‍♂️
Boolean 👌

GameplayTag (alternative) 👌

if you just need 2 state then boolean

[flat jetty]

Alright, but how i would still my input to work? Do i need another input for "GetKEyDown etc. " in UI?
Since I set "Input Mode UI Only", Input wont work to disable .

I am wondering how to toggle back, while we set Input Mode Only with same KEY

Maybe I should add another Input Context, remove my Player context, then re-add again..

[frosty heron]

if you don't need gameplay input when in U.I then handle the key in the widget.

well there's not one way to do it.

how you do it is up to the designer

[flat jetty]

I thought that would work.. But nah..

Why didnt work though. 😦

I simply want to Toggle with same key, I thought creating new IMC, and adding it as context would do the job. :/

[frosty heron]

Just use the same key?

you gonna press the same key to open and close anyway?

OnKeyPress-> If Inventory is not open -> Open Inventory -> Else Close Inventory

[flat jetty]

Yes, But the problem is; When I display Inventory, I call Set Input Mode UI only, which the behaviour I want, because i want to be able to focus on inventory itself, not allowing movement etc.

And when you set Input Mode UI only, it disables the IMC input, which the IA_Inventory doesnt fire event.

[frosty heron]

Then handle the closing of the inventory on the widget with OnKeyDown

[flat jetty]

Yeah, thats an option. But i want to stick into the Enhanced Input action, and be able to use UI IMC for myself, to close active popup. But i think this wont work. I checked enhanced input topics, many had the issue and solved with like this, removing old context, activating new one, and etc.

[frosty heron]

There's something called Common UI and it's got IMC covered afaik, but I don't use it personally. You can take a look at that.

[flat jetty]

Yeah anyway, I wont insist on this, and simply use "Get Key Down " inside the widget..

[dusky cobalt]

btw is this inside your widget?

[ruby ivy]

Is it possible to use the same variable with different values in the main actor and child actors?

[dusky cobalt]

that is how inheritance works so yes

[ruby ivy]

how can i do that can you explain?

[dusky cobalt]

just set new value in the child blueprint in defaults/details panel

[ruby ivy]

okey thanks

[kind estuary]

Why are data tables structs encouraged to be C++... I read they get corrupted. Something like that. What does that mean? Why do Blueprints struct get corrupted but not the C++ structs?

[frosty heron]

something with seriliziation and patching. W/e it is, it's broken, that's all you need to know.
Don't dwell and just move on with working tool.

[dusky cobalt]

Structs are often getting bugged in blueprints. In practice, when you change your struct (add variable, remove variable), there is not agood way of handling this if the struct is made in blueprint. Basically it doesn't get properly removed/updated in the places where you use it and then it might get corrupted that you either cannot open blueprint orfor example it will forever think it has that value, or the values you put will get reseted everytime you launch editor. Tons of bugs basically. And there is no good fix for that so that is why it's almost mandatory to make struct in c++ at this point. Just don't make them in bp and declare them in c++

[kind estuary]

🫡 yeah though this forces my project to be C++ making it several GB in size

quite annoying

[storm solar]

When making a widget, I have 3 players that can call it. How do i know what player actually owns the widget?

[frosty heron]

Widgets are not replicated and local.

Saying which widget belongs to who kinda pointless in context because it's not like widget is reachable by other players.

[storm solar]

So what do owning player and player controller do in this context?
Get the physical controller and the player connected to said controller?

[frosty heron]

What does physical controller mean.

For context, server have everyone controller.

But client only know their own controller.

Widget is local. Don't think about networking it.

Widget job is to just read.

[storm solar]

im not using it network wise. Its all client

[frosty heron]

Have you read the pinned material in #multiplayer channel?

Should give you a run down on mp framework.

[random pulsar]

hey
So i have an arena actor blueprint which spawns Necromancer boss when witcher overlaps with it,in the arena i have the custom event SpawnAllTypesOfEnemies.
And i wanna call this event from the Necromancer but i cant cuz cast needs the object input ,but i don't know that to connect there,also tried class but i cant access specific event from the arena

[frosty heron]

Kinda need to know what's replicated and what not.

[random pulsar]

I also tried with interfaces but also didnt succeed

[frosty heron]

Cast is just a type check.

[frosty heron]

You need to provide an object reference of the actor you want to access the method.

So the instance of the necromancer boss.

There could 1 necromancer, or 2 or 100. Which one??

You gotta point at one and say OK this necromancer , do this function.

[random pulsar]

i have only one on the map and i spawn it dynamically

[frosty heron]

Your blueprint is a template, it gets instantiated to instance that you spawn at run time.

The easiest to store a reference here is probably do it on spawn.

Have some manager to store that reference. If you don't want to use an actor, game mode can be a candidate

[frosty heron]

An object reference is just a pointer. It points at an object. So create one variable , name it necromancer in game mode. The type is your bp necromancer.

On spawn -> get game mode -> cast to your game mode -> set the necromancer variable to the return value of the spawn.

Now you have a reference to the necromancer you spawned. Do with it as you wish. Tell it to dance or kill it.

[random pulsar]

on overlap with arena i spawn and store him

arena has a reference to the boss,but i need the boss to have a reference for arena
to access one event from it

oh ok,so this will work as i imagine ,just a simple change,store the arena in game mode

[frosty heron]

Depends on your design. For level based manager. I like to just place a manager which is just an actor in the level.

Since there will only be one manager (singleton) i can just use get actor of class.

Using game mode is valid too but you might end up with multiple game mode for different levels.

Which is fine too, at the end of the day do what make the most sense for your system.

[narrow sentinel]

so am i being stupid but in UE 5.5 there not a + node for adding two rotators together

?

[dim siren]

Combine rotators node

[narrow sentinel]

yeah I spotted that node and when I used it wierd stuff was happening so for now I've just break and make ++ inbetween the other rotator stuff

[flat jetty]

No it was Player controller

[autumn pulsar]

is there a way to "favorite" settings? Like I have a child blueprint for a class, but realistically there's only a few settings you actually want to edit

[dusky cobalt]

only categories but they also kind of get lost in the details panel.. i saw plugin that lets you actually put these categories in order

[willow cedar]

When testing Listen Server in Edtor, Widget Components don't load that are attached to the Pawns from the Hosts perspective. How can I fix this? Using Unreal 5.5.3

I'm not setting the name, so it's not a replication issue.

Seems it's a bug that's unfixed in current version :/

[dusk forge]

is it possible to get rotation of actor who implemented animnotify

[iron stump]

I am decent at level design. I am not so much at Blueprinting. Can anyone tell me why the water splash particle effect won't activate behind my vehicle when it overlaps a waterbody? This is where i ended up when i asked ChatGPT.

[grim sand]

Instead of setting visibility you have to activate the particle effect

Also, the branch will only every make it visible because the branch isn't controlled by a boolean variable

[charred berry]

Chat gbt can only do so much don't rely on it for coding you'll never get anywhere you have to learn the right way search for your tutorials search through the tunnel engine depth tutorials you'll find all your answers there get to a plateau if you get stuck then ask

Not as hard as it sounds if I can do it you can do it 💙

[iron stump]

what is tunnel engine depth? i googled that and came up with nothing unreal related

[lunar sleet]

I would add that you shouldn’t just blindly search if you’re trying to learn UE. Try to build something and when you get stuck ask here or search the web for that specific issue, else you’ll be in tutorial hell forever

[iron stump]

That's exactly what I did. I tried building myself. Then asked Chat. And now I am here asking for help with a screenshot if my work

[lunar sleet]

ChatGPT hallucinates things when it comes to UE. You will end up further down the rabbit hole

It’s gotten a little better but still mostly miss than hit

As for your actual question

[bleak moon]

chat and other AI like things in my experience (not used them but seen results) are 90% wrong or just further down the rabbit hole, best to stick to forums (admittedly unreal forms arin't great) or asking here first

[iron stump]

So I can't have the effect set to not visible. And then hit something with the collision I set on my vehicle, to have that collision tell the effect to become visible? @grim sand

[lunar sleet]

You need to learn to debug.

Do you know how to use breakpoints ?

[iron stump]

No. I will look up tutorials for breakpoint.

[lunar sleet]

Just select a node and hit F9. Run the game. If it drops with a red arrow on the node it means the execution has reached that node. If it doesn’t, it means it never fired

What you want to do here is see if 1) the overlap event even fires. If so, then move on to the cast to see if it’s actually finding the right component. When the execution is stopped you can hover over each of the pins to see their current values

[bleak moon]

can also right click on the node and theres an option to add a breakpoint. its handy to to see what the results of that node is, for example on a branch to see if the result is in fact true or false

[lunar sleet]

It’ll help you narrow down your issue, just start from where it makes most sense. You can also use the arrows at the top to step through the nodes one by one

[bleak moon]

unreal is a little annoying where to see the results of some nodes you have to hover over it/ look at it, one step past it for example

[lunar sleet]

You can also use print string if need be

[bleak moon]

99% of a coders job is break points and print strings

[iron stump]

thank you for the tip. now i kmow my code is all wrong. lol

that does tell me something at least

[bleak moon]

every coder goes through this almost everyday of coding even 10+ years into the industry so dont worry about it too much 😛

[iron stump]

thank you. i could imagine. i look at the huge blocks of code on some of the material i play with, and I'm thinking to myself that i would tear my brain up trying to figure all of those nodes out

[lunar sleet]

Collision can be very tricky tbh. You’ll spend hours sometimes trying to figure it out 😅

[bleak moon]

best thing to do is try and not do everything at once, break the problem down into lots of smaller problems to manage. for example, i want my character to move over there, break it down to, how do i get that point, how do i move it, how do i move it by X etc etc

[iron stump]

I will keep at it. Breakpoints will help me. Thank you so much for that tip.

[bleak moon]

small steps is the way to go so no worries

[iron stump]

So, the only event i could get to fire anything upon startup is Begin Overlap. Thats a start. Now i cant figure out how to make the next node fire. the actor im trying to overlap is a static mesh set on a landscape spline. im not sure if i have the right node. but believe i do

Collision is supposed to be set at Overlap all?

[topaz goblet]

I'm working on an RPG type game. I have an Item system that utilizes structs for the various items. What's the best way to store large sets of item type data?
Like...
longsword - min damage, max damage, swing speed
shortsword - min damage, max damage, swing speed

[dusky cobalt]

Data Tables or Data Assets

[topaz goblet]

Awesome, thank you! I'll take a look at those.

[frosty heron]

It's most likely your code

Widget don't have anything to do with networking to begin with. They are not replicated.

[frosty heron]

When the anim notify is called you have a reference to the mesh component.

From there you can get the owner and access its rotation, etc.

[dusk forge]

i understand this but i could not find from the find component thing

[frosty heron]

Show your attempt when asking questions. It helps put things in context.

[autumn pulsar]

Is there a way to check if an animation slot is occupied?

[lunar sleet]

You can either use the arrows at the top or move the breakpoint down. When it breaks, hover over the pins to see what component is being overlapped. Note that collision can likely will trigger multiple times

[willow cedar]

Its not because all it is is a widget with text. I found a report on the forums of other people having the same issue.

Bandaid fix was to put the widget component in a seprate actor, then put that actor in your pawn as a child actor compone t

Also, I didn't have any code. It was just putting a widget component on a pawn and setting it to screenspace.

[frosty heron]

Seems like 5.5 then, just read an article

One of the reason I don't rush to upgrade. Sometime they break things that already work as is.

[frosty heron]

Child actor component is not really bandaid. I rather not use 5.5 than if I have to use the cursed component.

[winged pier]

Anyone know a way to change the categories for certain variable types when creating new vars, so you can make them show up at the top of the list rather than having to search for them?

[dusk forge]

This is AnimNotify(AN) BP. Trying to get location/rotation of actor who implements this AN

[frosty heron]

Are you overriding on begin notify?

If you do you will have an input parameter called mesh comp

Drag from there and type get owner

Then you can cast it as an actor and get the actor location.

[iron stump]

Okay. Thank you. I did that. It now breaks when i get into the river. But now i cant figure out how to make the Get water splash node to fire. or if that is even the right node for the job.

[flat jetty]

My default values are always in middle or bottom in the details panel. In videos, its generally at top. What does it affect? I generally find those variables by searching the panel.. a bit tiring.

[frosty heron]

You can assign category.

[fervent jolt]

you might not be using the right node. if the water splash you mean is the component of your actor named water splash, it can be accessed like any other variable in the variables section of the blueprint editor in the bottom left in the components category dropdown or by dragging the watersplash component into the graph from the outliner. both methods will give you a reference which will allow you to access water splashes methods.

or what you got should still work though? I think that node is for when you want to make sure an object is valid before accessing it to prevent a crash.

[dusk forge]

yep this is exactly what i was looking for thank you

[spring magnet]

Has anyone solved saving/loading actors in a World Partitioned project??

Yup, I got one. Snatch it form lyra, called common maps.

i have a problem, im usign the node set simulate physics to true of an item, but it never works

so my blueprint is BP_Rock

i spawn these rocks all over the environment

via PCG

but when they're on the ground I dont want to give them physics

when they are on your hand i want to giv them physics because thats where you can throw them

to throw them and add velocity to them you need to have physics on it

[fervent jolt]

theres like a function you have to call i think, its like, wake actor or something

[lunar sleet]

Wake all rigid bodies

my problem is the set simulate physics node doesnt work

if i go on the details and set physics to true then it will work

but it will also work for all my environment rocks

but anyway

it's just a simple Set Simulate Physics node

anyone aware of a way i can set a integers range inside a child blueprint?

[subtle ocean]

Is it possible to fade static mesh without changing the materials (because it'd be way too long to modify every materials) ? I can't find any tutorial to do it on internet (they all talk about materials)

Oof. Shoulda used a MasterMat. You could use some post processing limit effected components

but that's prolly the most inneficient way so i dont even know why i mentioned it

i'm going back to Gundam

I am using enhanced input system and auto filling out my bindings which I have working perfectly except a few of my bindings have corded actions I want to edit my widget to show the corded action but to do so I need a blue print to figure out if the action input is corded. Right now I am just passing the inputkey and the user settings (enhanched input user setings type) into the widget and grabbing its data to populate my widget. Can I some how use the input key or the user settings to see if the action is corded. If not is there any data I can pass into my widget to do so?

TLDR: I want to know if a input action is corded(need another button pressed at the same time) and modify my widget if it is.

[frosty heron]

No, use materials for anything with opacity.

[wicked cairn]

Hey all, anyone know how I can get my actors, when dragged into viewport onto the ground, to take in account the actor's bounds when being placed? Currently It just places it taking from the actor's origin, making some objects clip into the ground. I have a collision component that acts as the object's bounds. Is there something I can enable?

As a further example, when placing character or pawn actors, the capsule's origin is in the middle but when dragged onto the ground from viewport it will always line up and sit ontop of the ground and not clip in it.
1st pic is what it does, 2nd pic is what i want.

The 3rd pic is what I use to add to the location of when I'm spawning the actor during runtime to make sure it doesn't clip. Any help appreciated!

These are the collision settings for the collision component

[marsh sonnet]

Hey y'all! I know how to switch on enums and also have done that for, like, movement mode... is there a way to get a switchable reference for all potential children of a parent actor?

[frosty heron]

Wdym by potential children of a parent actor?

An enum is declared in fixed length.

Pretty much just a named integer.

[lunar sleet]

All potential children == the parent

[split dagger]

Have you tried selecting your actor, move the actor above the surface, and press "end" on your keyboard?

[wicked cairn]

Ooouuu i suppose that works, thank you

[split dagger]

Nice!

[rain egret]

What are some settings in blueprints that improve performance, example like unchecking tick, collision/ overlap and can affect navigation

Furthermore, why is a actor with 10 components better than a actor with 10 child actors/ attached to actors

I am working on a modular building System where adding parts is translated into attaching components. This ought to improve the performance compared to the old system where it was a bunch of actors that got attached

[gentle urchin]

during compilation you dont compile the components of an actor (unless you're specifically compiling and editing the component)

components tend to give better code with more focus on reusability

Isnt there a setting these days that turns off the tick by default on all new actors ?

traces are dirt cheap, but overlaps run async iirc

an actor in itself is just a container of components

runtime wise, assuming all other things are equal, using attaching components vs actors shouldnt mean much for performance

Using tick is fine for a building system (since you asked about tick)

rest of the optimization mostly lives in your code

[dark drum]

It checks if the tick node has been implemented and handles it accordingly. If you're not actually using tick, you don't even need to disable it as it'll do it for you.

[gentle urchin]

I've never really tested if that holds up

was under the impression that that was whats supposed to happen, but idk

it's clearly what the comment states about greyed out nodes

[dark drum]

Either no tick node or the gray/ghost one. If you add the tick with nothing attached it'll still tick as it doesn't check if anything is connected to it.

[gentle urchin]

So i guess noo node or grey node puts it in the "can never tick" category then

[dark drum]

🤔 I guess so, I might have to double check the actor class again lol. That thing is a beast. 😅

[gentle urchin]

huh is this new ?

[dark drum]

I wouldn't know, I've only been digging around the c++ in the 5.5 version.

If you search for implements you should be able to find the bit where it checks if tick is implemented in BP.

[gentle urchin]

damn its a rabbit hole again 😄

[dark drum]

You should look at how the construction script works. 😅

[dark drum]

Simply put the actor class is a beast that does a lot of stuff just to exist in the world. A child actor component, just spawns an actor in the world with extra steps.

Actor components are lighter in comparison as the actor it's placed inside does most of the leg work.

For bulk meshes, you can look at instance static mesh components.

[grim timber]

can anyone help link these systems together? #1348148528270020648 message

[frosty heron]

I think the part where it takes the heavy toll is the transform.

[digital palm]

is there a way to know with one trigger box, if the player comes from one side or another?

[frosty heron]

Dot product

[digital palm]

nvm, I did player loc X < box loc X

[gentle urchin]

that only works if the actor is placed in that exact direction

dot product works regardless of rotation

and will always return the "correct" side

[frosty heron]

I don't graduate from school and my math is very rusty but I think you want dot product of your actor forward vector and actorLoc - PlayerLoc

If the value is 1 then they are facing the same way, thus if the player enter the trigger and the value is somewhere around 1 then he is coming from the rear

-1 if from the other side

[gentle urchin]

= 0 = = one side
< 0 == oother side

[frosty heron]

🙊

[gentle urchin]

depends on whats an "acceptable" angle to come from really

you may want some >= 0.3, < -0.3 to avoid 90 degree entry

[frosty heron]

Normally I just print the value on tick and see what the ideal angle of attack is

[gentle urchin]

that or set up the visualizer 😄

[rain egret]

Bulk meshes, so different individual meshes, I will simply solve by using a procedural mesh component and create a section for each new mesh, was just wondering if my approach is the performant one

[dark drum]

Unless you need to actually generate procedural meshes (defining verts and tris) you'll be better off using ISMC. There's overhead for using procedural meshes, mainly updating them IIRC.

[rain egret]

Yes but a ismc can only have one mesh that it duplicates, I want to have multiple

For example, you add a cube, then a sphere and then a cylinder. A ismc can only ever do one of these, unless I add one for each possible shape that I'd want to add.

[dark drum]

You would have multiple ISMC's. You'd most likely need to make a manager for it. The foliage tool does this. It creates a dummy actor and then adds a new ISMC for each mesh you paint.

[rain egret]

Take this image for example, the wings would be a static mesh

Hm so what You're saying create a logic that automatically adds a ismc for each new sm that id wanna add

That could work, thanks!

Hi, is there a way to check if all events on sequencer are triggered and eventually trigger them? Sometimes my events on frist sequencer aren`t triggered. Sequencer skipping some frames becouse of level loading [and other stuff] at the same time at least that's what I think it the case. Is there a way to fix it? If i skip cut-scenes with code (set playback position) it also trigger all events but only with remaining time.

I’m looking for a way to use the switch on node and make it auto populate the children of a parent blueprint

[past compass]

is there a way to customize* the camera from blueprints? for example, getting it to recognize when im inside a building so it changes the camera for the player ?

[graceful sage]

Can use an overlap?

[narrow sentinel]

out of interest what would the performance impact be for these two scenarios -

I have all the doors within persistent level but tick disabled.
I have the doors within respective levels

bassically what I have is a console on deck 01 which shows status of all doors. I don't want to have to load Deck 2 & 3 levels just to get the data from the doors to then unload the two levels.

the only method I can think is the doors exist in persistent level but at moment not 100% sure

[past compass]

you mean like adding a trigger / overlap inside of the buildings? i could, but that seems way too manual of a process to keep track of, like not sure how i'd always 100 percent be able to know via an overlap box position if they are inside or outside of a house

[crisp hollow]

Hey I have a question about construction scripts. I use it to generate a mesh plane (just 4 vertices) based on a texture size, however the mesh is not saved when I save the level. This wouldn't be a big issue if the mesh would regenerate when I load the level but it doesn't, not even when I play the level. Am I misunderstanding the purpose of construction scripts or a missing a feature to enable the behaviour I want?

[dusky cobalt]

Building has collision box, when player enters it you cast to camera and ifnorm it it should change.

[past compass]

right, i just think that would be tougher to manage, but it would work. i woul dhav eto have the colision box overlap pretty much the entire buildling so that if you are in the building yopushould be in the collision box. issuse there is not all houses/buuldings are cube like in design, so that would require multiple collisions boxes etc, the method would just stack problems imo. there's gotta be another way to approach it

[dusky cobalt]

you dont have to put collision in every building individually, just make new actor that is BP_CameraChanger with simple collision box and place it where you need to camera to change. If the shapes are different then just put 2-3 collision boxes so they cover whole place.

[warped folio]

Hi I'm working in 5.5 version right now and trying to build something with blueprints. In the tutorial the guy use something called "Get Character Movement" but it's not there anymore ?

[dense badger]

This is an odd one: Whenever I restart my project, one of my widget BPs has a pin that breaks. If I hit refresh all nodes or recompile it compiles fine. Any ideas why it's breaking?

[dusky cobalt]

You need to be inside Character class

[dusky cobalt]

bug, delete and create node again

[dense badger]

I have done that already, but I'll try again.

[dusky cobalt]

like delete whole spawn actor of class and set it up again

[past compass]

wouldn't i need to place that actor inside the buildings individually tho ? i would just put the collisioin boxes in the building bp's and then from there i'd do the logic which would actually make it so i wouldn't have to do it on each house, but still would just have hundreds of those boxes in the world then, not sure if that would really be an issue either but it would be a lot of extra boxes just for the camera change trigger

[dense badger]

Yeah rebuilt it from scratch, restarted, still broken.

[dusky cobalt]

what does error say? maybe its exposed on spawn but not instance editable?

[storm solar]

With a multiplayer game, when setting and controlling a widget w/selectable buttons... will Setting the Owning Player input to Get Player Controller only allow one person to interact with said widget?
Furthermore, once a button on that widget is selected, I want to "lock in " that choice. Keep the widget and buttons up but disable other button choices in the widget. Is this done by just disabling the other buttons?

[dusky cobalt]

remove and add variable? maybe its corrupted somehow

[dense badger]

Trying that now ty!

[dusky cobalt]

or you have 2 variables one in parent or something like that?

[dense badger]

There's no hierarchy it's just a base drag and drop operation

[dense badger]

It seems to be something with the name? Deleting and replacing with the same name, breaks. Puting a new variable name seems to work. Thank you!

[dusky cobalt]

restarting editor could probably help, like save, dont compile and restart, then compile

[dense badger]

I'm gonna assume there's a hidden variable name collision in the base class, though it would surprise me since I'm using the naming in the default Unreal tutorial for drag and drop operations... shrug

[iron idol]

hey guys, need someone to check if i'm doing this right. I'm trying to cast to an actor and call an event within the actor, but the event is not showing up

i drag off of "as Blood for Blood" but the event within the actor is not coming up. I have made sure everything is complied and saved. I swear I just did something similar to this the other day, not sure what I got wrong this time around.

[runic terrace]

That is a class reference

[iron idol]

yea i'm just realizing this haha

i found the other code i mentioned

i take it i need an object reference

[runic terrace]

yeah you need it to exist

[iron idol]

i take it the actor needs to be in scene

[fallen glade]

is there any way to re-trigger the construction script from another Actor?

[dark drum]

No but as a work around you can put the logic into a function. Call that function on the construction script but it then becomes logic you can call from somewhere else.

[fallen glade]

Thank you I was trying to aboid this as i'd have to do a lot of faff again but I guess I have to

[crisp hollow]

After further investigation, it seems that the BP is loading a texture with the right name, but the size properties of the variable Texture2D is wrong and set to a default value of 32x32. Is there any way to delay the execution of the construction script until the Texture2D variable has been loaded, or to at least schedule an event that executes once the Texture2D has been loaded?

Changing to the BeginPlay event is not really an option for me.

I can't just check if the size is 32x32 and say this is an invalid size because the texture that's set might be any size

[calm cargo]

whats a good way to check if the world is tearing down?

basically the BP equivalent of if (GetWorld()->bIsTearingDown) ...

[rain egret]

whats up with my for each node

[dark drum]

bIsTearingDown isn't exposed to BP in anyway from what I can see. The closest you'd get is the OnEndPlay i believe. It should give you the reason as well.

[dark drum]

Other than it not being a foreach node, whats the issue?

[calm cargo]

Thanks for that 👍 I think I'll add a quick BPFL or something

[rain egret]

i was trying to be funny : (

I'm trying to remove these old variables and the editor just starts looking for references (of which there are none because I replaced the variables) and building random meshes and it's just stuck... Any solution for this?

(4.27.2)

[sudden nimbus]

unfortunately not, the editor is trying to be helpful by finding any references remaining. usually just does this for type changes though. Just wait it out while it does the work, the results will be saved for later anyway

[wild crater]

But the variable has 0 references lol. And it's building meshes

just seems wrong

[mild pine]

Hey guys. I'm working on respawning and when I'm setting my actor's rotation I want it to respawn facing towards the respawn point. I get the rotation like in the image, where Target Mesh being the player's mesh.
The problem is that my character has a camera attached to a springarm which is attached to the character's head socket, and has UsePawnControlRotation enabled (it's a true first person setup). This results in the springarm not rotating with the mesh, because it's still getting the rotation. Before setting the rotation of the actor I therefore disable UsePawnControlRotation on the springarm, but it still does not work properly.

Anyone got some tips on how I can deal with this? 😅 Seemed like such a basic task but suddenly it's become a proper bain haha

[faint pasture]

why not just set control rotation to be what you want it to be?

You'll have to do it clientside when a respawn is detected

[mild pine]

Okay so Set Control Rotation has avoided me apparently, that seems to be getting me closer. The character is rotated slightly off though 🤔

It's consistent though

Got it working - got the ForwardVector of the spawnpoint and made a rotation from the X vector.

Thanks a lot! 👏

[spiral widget]

Is there a way to force garbage collection and clear the PCG cache within a BP? ❤️

[honest arch]

does anyone know how blueprint debugging mode can fail?

it hit a breakpoint and stopped though, even if it failed. im not getting any information though

hmm

Hello Theo,

have you tried Arcware Cloud ?

[wraith loom]

I've seen people have blueprints where the lines connecting nodes are different (like having straight lines instead of curving ones). How do I change those visuals?

[velvet trout]

can anyonw help me with creating this powerup that should add time to the timer widget? I can't find a good example of one online and I've been trying to make it for a while now😭

I want it to add time when begin overlap,but it doesn;t seem to be working

[wraith loom]

What are you trying to do on begin overlap in the second image?

[velvet trout]

the second image is the powerup so when the player collides with it it should add time to the timer

[wraith loom]

Well in the image it's definetely not doing that. Is countdown the timer, is it a public variable, and is it located in the widget? And why aren't you setting countdown in that image (and what is the 0-1 clamp for)?

[topaz goblet]

Yeah, I was going to ask about why the execute for the set wasn't connected in the second picture.

[velvet trout]

idk, i was following a youtube video and reddit posts and that's what they did

😭 so lost

[topaz goblet]

I'd suggest watching some beginner tutorials to understand blueprinting.
The execute connections are important.

Mostly because copy/paste coding stuff works for a bit, but really needs to be tailored to your application and implementation overall.

[thorny marsh]

Please stop shilling your product here. You will be removed if you continue.

[surreal wagon]

Any help is appreciated.

[thorny marsh]

The error tells you exactly the problem.

A property of type Array is not the same as a property of type Set.

Delete the Add node

And make a new Add node from the Inventory property.

[rain egret]

i came up with something and it works wonderful, thanks again for the idea

right now it removes the ISM indexes per wall

for when the wall gets removed and the parts fly freely

i will not get past having animated parts be Skeletal mesh components but for those i will simply give a hard limit, like you can only have 10 engine or something like that

[thin shell]

Hello everyone !
So here it is, I am currently researching to create a game. However the tech and blueprint part is my nemesis.
I would like to create a crafting system, however after watching the tutorial by "ryan Laley" on the inventory system, I am struggling to find the elements to make a crafting system. (2 slots. If the 2 elements placed in the 2 slots are good, then craft the object).

I would appreciate help from a patient person, ready to help me on this feature. If you speak French it is a plus in terms of communication but English is also fine for me !

I have literally no clue how to do it and everything i tried was a disaster haha 😅 (Working on UE5)

[tame geode]

This is similar to what you are getting, it might help. https://www.youtube.com/watch?v=rgGTOZmJv9g

[honest arch]

ty

not the error unforunately

[tame geode]

OK worth a shot. I haven't see that specific error. Do you have the BP Debugger window open before you run your code and get that error? If so, does it show any error message with more details? Anything more in the console log?

[honest arch]

i do not. ive restarted my editor already and have moved on from those areas of the code. i think i figured out where i was having trouble without that anyway, and the issue isnt replicated elsewhere

[fierce crypt]

What would be the simplest way to situationally attach the camera springarm to a specific bone on a skeletal mesh? basically, I want to attach the camera springarm to the character mesh during certain abilities, and have it simply attached to the capsule otherwise.

if this is better done in C++ with maybe a library function, that is also an option

[frosty heron]

@fierce crypt i don't think it matters to do it in bp or cpp. After all is just one node?

[fierce crypt]

wait actually? which node?
