blueprint

[hearty veldt]

no need to do Get to query a 2nd time, you already have the item itself inside the Random node

[mild ibex]

anyone used this node before? Trying to convert srgb to linear colors

[elfin hearth]

don't know this node but you can try to disable " is srgb" in your texture if that's what you're looking for

that's what I do when i get linear textures looking weird

[mild ibex]

its not a texture. I'm creating a color with some floats

I think I just have to do some gamma conversion which is fine, just not sure how to use this node.

[hearty veldt]

no idea about that node, but you can try this https://lettier.github.io/3d-game-shaders-for-beginners/gamma-correction.html

By raising the color values to the power of 2.2, you're converting them from sRGB to RGB or linear color space. This conversion has the effect of darkening the colors.
The 2.2 value is known as gamma. Loosely speaking, gamma can either be 1.0 / 2.2, 2.2, or 1.0.

[rotund barn]

wait so how did you create that thing that contains 3 data types per index? i tried using maps but those can take only 2 data types/variables.

[hearty veldt]

like I said, it's a Struct, you can put whatever number of items you want in them, and then make an Array of that Struct

Maps can work in your case as well, but keep in mind that the index, the first item, has to be unique, they're like a Dictionary in that regard

[elfin hearth]

for some reason my mesh is rotating at the opposite of the sun. I added rotator so it's pointing to the sun but it is still inverted when sun goes toward the ground, the panel point to the sky

[mild ibex]

I've just gone with this. The resulting rgb is a number or two off out of 255 which is a margin of error I can live with.

[rotund barn]

yeah i already concluded maps wont work cause i need way more than just 2 data types. but so do i need to create a struct for every item? and can i add structs inside of other structs or is this bad practise?

[hearty veldt]

no, you don't need 1 for each item, you can just have a generic one

[modest compass]

Does anyone know of a way to make a Level Snapshot through Blueprints? I would like to use that system as a way of saving states of my "game"

[rotund barn]

im probably doing something wrong, my struct doesnt let me group things like in the picture you showed. i can only add the different variables but they would all be together, not like for you they had an index per 3 of those variables.

[hearty veldt]

you mean the Make and Break nodes?

you can also right click and choose break if you don't want another node, it's just like split on vectors for example, I'm just not a fan of it cause it makes a mess, especially if I have a lot of data in a Struct and makes it harder to see just my own data

[crude dew]

Can someone tell me how you can adjust a Projectile Movement's speed during runtime please? Set Initial Speed and Max Speed are all calculated upon spawning if im right and Set Velocity seems to do nothing.

[rotund barn]

no but like you had 3 data types grouped together with one index per 3 variables. or do i need to create an array of structs?

[hearty veldt]

yeah, that's just an array

[rotund barn]

im sorry im so confused, how can i create an array of the struct?

[willow gate]

So I'm running this right in the player controller and setting variables OnBeginPlay which I pull from the other BP but it's just returning 0,0,0 no matter what I plug in to ConvertScreenLocationToWorldSpace

Tried it in the EventOnPossess node as well

[hearty veldt]

you can set the Velocity of the Projectile Movement itself, which is just direction and speed, you can try to multiply your speed with the forward vector, see how it goes, never needed to modify speed after launching them before

[hearty veldt]

probably because the cam is not there yet, might not be initialized, or moved in its position yet I tested it while playing, when I had the regular view of the game and the cam and everything already running

try doing it while playing first, and then fiogure out what's the best place to move it to

[willow gate]

Roger. I'm moving it into the Character BP to see if I can do it there after seting the view target to the spawned camera.

[hearty veldt]

whenever I test something I use debug keys like this, so all systems are already running, and then I worry about moving the logic

[fathom widget]

Does anyone know why "Add Data Table Row" Doesn't do anything? I've looked on the forums, but can't really find an answer.

https://forums.unrealengine.com/t/set-data-table-row/85844

This kind of addresses it, but it appears most people are having the same problem as me and it doesn't actually do anything. I am even saving the assest after I add the rows I need, but it's not doing anything. When I check back in the editor, it's unchanged. Any help would be appreciated.

[willow gate]

Cool. That's working once everything is up and running so I know where to call it from. I either need to make separate actors for my two corners or I need to figure out how to convert world location to relative.

[crude dew]

Thanks, I was looking to do like a projectile attack but the player can control the projectile whilst in motion which also provide a speed boost to it. 🙂

[willow gate]

So it's returning strange numbers. Is there some conversion I'm missing here? Moving my colliders to the cordinates in the screenshot is obviously just a very small area that doesn't actually reflect a bounding box that covers the whole screen space.

[willow gate]

I'm trying line traces from those corners but they don't want to go straight down from the camera, they want to seek the center of the camera it seems. Or else they are just so close together and I don't know the math to acount for the distance between the "floor" and the camera. This is one of those unreal engine frustrations to me where I feel like it should be simple but its not.

[marble tusk]

Yeah, I'd recommend using the make and break nodes for custom structs instead of splitting pins. I've had it happen too many times where I make a small change to the struct and everywhere I split the pins now has broken connections. Doesn't seem to happen at all with make and break nodes though

[rotund barn]

ah, i feel so dumb now, i was trying to do it inside of the struct. but thank you very much for your time.

[proud bridge]

Hi, is there any console command to change engine scalability settings?

[gloomy holly]

hello all, so i am wondring if anyone here is able to help me?

i have this issue:

i want to be able to choose between these UV maps in unreal engine

Here in unreal engine you can see it has the texture and the UV number is set to zero, which is the colour brown, when i change the UV to 1 it goes to blue, when i change it to 2 it goes to yellow, 3 is red, but when i change it to 4 it goes blank, can anyone help me?

ok, so i have just retested and it allows me to go up to 7 and changes the colours correctly, can anyone help me to make a blueprint that allows me to choose the colour at random?

[frosty heron]

You most likely need to pass a ref for the row handle. Show your code

[rose bobcat]

I am trying to make the flying movement go in any direction like in viewport mode. So I want the character to fly up if I am looking up by pressing W. Right now it only moves on a 2d plane.

[hearty veldt]

you shouldn't need any conversion, that node I showed already returns world coords

if you can't figure it out, I'll try to dig out an Unity project where I was doing the exact same thing in order to spawn enemies outside the camera view frustum, and see if I can port it over to blueprints, but that might be tomorrow, not making any promises

[proud bridge]

. Anyone pls?

[willow gate]

Appreciate it. I think the problem is that it's getting world coordinates for the literal lense of the camera where I need it to be projected down to where the player is standing.

[hearty veldt]

in that case you REALLY need to set Velocity, otherwise you can't modify rotation, direction, they get overwritten, if you hover over the ProjectileMovement it gives some details about this

updates the position of another component during its tick

[hearty veldt]

have you tried Scalability #?

like for example Scalability 0 up to 3 if you have the default ones, not sure, mess around with them

[hearty veldt]

https://www.youtube.com/watch?v=EI0j3pCAT0U just change the loop at the end with a random

[gloomy holly]

thank you very much, literally watching this video now, i am trying to make it so when a player spawn into the level he gets one of these colours at random

[ornate trail]

why would a camera shake be rotated? like I don't see it unless I move the mouse to see it from the side

[gloomy holly]

i currently have this for spawning player colours:

where would i add in the UV selector random generator for player colours?

[hearty veldt]

maybe you're shaking on only that one axis? or maybe the effect kicks in when you rotate? use some breakpoints and prints and check if it works when you want it to, before you move the mouse

[ornate trail]

I was using the tree I was hitting, changed it to the owner location and it works

[hearty veldt]

serves you right for hitting trees then

[pearl flame]

Hi! So I've made in UE 5.2 a mouse over event, and somehow it just stopped working in 5.4, do you have any idea how could it happen? (mouse over events are enabled)

[pulsar vigil]

im currently using a set timer by event for one of my system but i have to change the time the event tick dynamicaly what solution do i have ? Like the frequency has to be updated almost on a frame tick

[lunar sleet]

Restart the timer after changing the interval

[pulsar vigil]

thx i saw it was the comon solution but it might not work realy well for me cause its a lot of logic to handle to be reset on frame maybe does that sound a bad idea then ?

[lunar sleet]

How is it a lot of logic? Change a variable, fire the set timer by event again

It’s not rocket surgery 😀

[pulsar vigil]

yeah ur right i just imagined it being weird somehow thx ❤️

[hearty veldt]

why you need it every frame tho?

just do a delay till next tick

[queen vault]

Is there a mid overlap event for a box collision? I want the event to run anytime the player is overlapping with the box collision. (Never mind, I figured it out)

[hearty veldt]

while inside of it? there is one, but can't remember the name rn

[queen vault]

There is no while inside of it.

[mild ibex]

im trying to index 50 actors, some blueprint and some niagara actors, each with a unique position with a slightly different name relating to that position but I'm not too sure the best way to go about it.
I do not want to go through each actor and tag them incase I swap levels and the name doesnt persist. I know I'm going to have to manually go to each actor but I'm curious what the best method is.
my current plan is to go through and make an actor component with an enum but that doesnt seem like too much of a good idea, im not too sure.

[pulsar vigil]

lmao that was my next question cause indeed it reset the timer and the tick never happen -_- and i need a solution for that, i need to refresh it everytick cause the tick rate change depending of the current speed of an anim montage play rate wich is himself updated by a timeline its a bit weird

[pulsar vigil]

i need to do a delay till next tick sync with the previous time of the timer, idk if its understandable

@lunar sleet @hearty veldt the thing is i need to update the tick rate on a almost frame tick of an event ticking himself between 0.5 and 1 second each time, so it will probably constantly reset im assuming

[hearty veldt]

indeed, there isn't, Unity has it, Unreal doesn't, but you can just keep track of what's inside, with on begin and on end, have a bool, an Array, depends how many actors you need to keep track of

be careful how often you run the logic on them tho, try not to use Tick, instead have a delay and run it a few times per second

[hearty veldt]

I'd let them register themselves when they initialize and then unregister when they're destroyed / despawned / whatever other logic you're using

this way they're calling home and you don't have to add anything special to them, besides that code

[pulsar vigil]

@lunar sleet @hearty veldt i know what to do i confused myself because there is multiple thing ticking for not the same purpose

[queen vault]

I've been trying to get this loop on begin play but it doesn't work. How do I do it? The reset happens at the end of the event. I thought do once made it so you can loop it.

[hearty veldt]

every 0.5s means a lot of ticks, a tick is a frame, not a second, which is why using ticks is frowned upon

[pulsar vigil]

yeah but i dont know how to call it cause that tick to even if its not a frame tick

[hearty veldt]

are you trying to make an idle clicker?

[pulsar vigil]

who ?

[hearty veldt]

you

that's the only reason I can think of where you'd need a lot of timers and they'd constantly change

[pulsar vigil]

nah im doing an input that control the speed of the current anim montage playing but also inmpacting the damage taken during the animation montage
its like a system of damage if the anim montage is playing that is updated in function of the playrate

[hearty veldt]

and you need ticks for animations? just how fast are these animations?

[pulsar vigil]

hmm what do u mean ? the input directly update the speed so it has to run fast to look smooth

[pulsar vigil]

concretly i press space bar and the animation go gradualy faster with a progress bar showing the speed acceleration, and the damage system need to be updated with it

[hearty veldt]

if you're using input why you need delays? input already has its own events raised when you press the key

[pulsar vigil]

cause while the input is pressed the logic stay active this is where the thing need to be updated

[pulsar vigil]

i mean i might not be able to explain it simply but its like the more u hold space bar the more it accelerate if u let the space bar go it gradualy decelerate to origine

[hearty veldt]

ohhh

okay I get it

still, must be a better way than abusing the poor delay

[pulsar vigil]

yeah i mean im not gonna use delay ur right since its driven by event too and i just have to update it every time the first event on timer occur as u suggested even if i dont know u made it on purpose

[hearty veldt]

surely there must be an easier way, I'll give it some thought, not something I ever had to deal with before

[pulsar vigil]

what im doing is not extraordinary technicaly im pretty sure but its clearly weird lmao

[hearty veldt]

yeah you're just thinking about the entire thing wrong, in 12 years of programming I concluded that if something doesn't make sense it's probably cause you're approaching it the wrong way and there are many solution way way easier

this is one of the reasons why I switch between projects, so I work on multiple projects at the same time

otherwise I start not seeing clear solutions anymore and I burn out

[pulsar vigil]

yeah ur right but i didnt fixed it yet i tell u if its working as intended which it should dw

[frail onyx]

is it normal for the blueprint menu to be kinda laggy if ur zoomed out all the way?

[daring merlin]

if you're using a shitton of nodes yeah

consider splitting up your graphs into multiple graphs (or collapsing certain parts into functions)

[daring merlin]

Tbh I don't see anything wrong with the timer approach you got suggested at the beginning

[frail onyx]

this is the one that's kinda laggy its my main player bp

[pulsar vigil]

it work perfeclty thx to the suggestion of @lunar sleet and @hearty veldt ( ijust tried and it work that why i say that) i thought i would have to change a lot of code ngl im happy :p

[daring merlin]

yeah that looks about right, still consider making multiple event graphs based on functionalitites and their categories/types c:

[odd kiln]

Hi all

[frail onyx]

ok thanks

[odd kiln]

Anyone knows if I can change the "Lighting Channels" checked by default ?

[quaint fable]

Hey! I was wondering if anyone could help me understand arrays better? I was reading up on the basics, but I can't seem to get it to work right.

I'm trying to create an array that references 4 specific objects/blueprints in the level. Then I'm trying to plug said array into a for each loop, with the array element getting a variable from each object. Let me know if you need more details

[odd kiln]

Or do I have to modify each Mesh one by one ?

[daring merlin]

yeah what's the question? c:

[daring merlin]

You can write an editor utility blueprint to gather all desired actors from a scene (you can filter them any way you like) and apply your changes to them automatically, otherwise I'd guess yeah, gotta change one-by-one

[quaint fable]

@daring merlin oh yeah my bad. How can I make it so the array is referencing these 4 objects while also getting the variable "Activated", which is a variable in the object blueprint? I'm working on making it so you have to activate all 4 of these objects in order to open a door

[odd kiln]

Ok thank you I'll try that!

[daring merlin]

Look into "Editor Utility Widgets", there's quite some content on youtube of them already c:

[dawn gazelle]

This is how you loop through the entries of an array allowing you to access each "Generator" in the array one at a time in the "Loop Body". If you're having trouble connecting the "Generators" array into the For Each Loop it's because it doesn't match the expected type of your target array element. If you change the type of Generators array to match then you should be able to connect it.

What you would likely want to do is have this in a function that returns false if "Activated" is false but returns true if the loop gets completed. Then you can call this function to check if your generators are all set to true or not.

[odd kiln]

Ok thanks a lot ^^

[quaint fable]

Thank you! I'll try that

[quaint fable]

That's basically what this guy was saying from this link https://forums.unrealengine.com/t/how-do-i-open-a-door-with-multiple-switches/758696/2

So basically what I'm having trouble with is figuring out what to set as "type" for the variable

[daring merlin]

The array? It's the type of your base class (for anything interactable you want to include in this), where you put your Activated bool.

[quaint fable]

the parent class for the "Generator" says actor, which is what I have the array set as. I have it set as array object reference

[daring merlin]

Then Generator is your baseclass

wherever you put your Activated variable

You want to use the classes that are the most 'generic' that still have all the info (variables) you need. For future reference, interaction based stuff would most likely be done via interfaces, but this should work for now.

[mossy lantern]

anyone know how to do a RGB loop on a widget?

[hearty veldt]

You don't need inheritance here. I'd use an Interface something like BPI_Interactable, and when you try to interact with them, if they have that interface implemented the code will run, otherwise it won't, and then simply have somewhere in a persistent / global manager the state of your .. generators you said they were?

Since this is something that is found in a level and maybe never again, or next time it might work in a different manner, I would put the tracking logic on whatever it is you're trying to unlock. Could be as complex as keeping track of each individual generator or as simple as having an int and when it reaches the max value, it runs the unlock logic.

When you'd interact with a generator, you'd tell the whatever it is you try to unlock to do a ++ on that counter int, and check if the counter is high enough. Also flag the generator as used / not interactable anymore, so players won't spam the same one.

[hearty veldt]

you mean animating a bunch of colors / gradients on a widget? look into UI Material Lab has a lot of eye candy samples like that

you can find it on the marketplace, is a free sample project from Epic

[hearty veldt]

I find DoN and DoOnce to be wonky, if a regular ForLoop won't cut it for you, try a Gate, something like this - except the bool at the end there, that's not needed, it's a leftover from something else

also here's a quick explanation of how it works, so I won't have to type it https://www.youtube.com/watch?v=utMuBhYLPMo

[rigid summit]

So I know that casting causes the game to load everything that the particular blueprint may reference. While it may not be best practice for every use case, would casting to player character, controller, state, game mode, state be "fine" since it is always loaded?

[daring merlin]

Yeah casting to base classes is fine c:

[lunar sleet]

Yes

[daring merlin]

Imagine responding after 25 mins in the same second 🤔

[lunar sleet]

Casting in general is fine unless that class has some very heavy refs you don’t want loaded

[vocal ferry]

I’ve been banging my head against this wall for some hours now and I just can’t figure this out. I am using this method to add weapon trails and it was fairly straightforward.

When I try to do the same thing with a muzzle flare by spawning at location, it says the type is incompatible.

I can connect the pin straight from the array into the emitter spawner just fine as shown, but using that method I would be unable to address the UserColor parameter to change the color before spawning it.

Can anyone help me get understand how to get these to work together, or simply how to use a “Cascade Particle System Component Object Reference” to spawn at a location?

Many thanks in advance!

[lunar sleet]

Cascade is a diff system, precursor to Niagara I believe. Try spawn system at location or spawn system attached

Not sure if they’re compatible but yeah, worth a shot

[vocal ferry]

Yeah, I've tried pretty much every variation of those that I can find. If I had to guess, it seems to be an issue with the systems being stored as a component within the character's blueprint

[graceful sage]

I'd personally just move it to a niagara system but thats up to you

im not too familiar with Cascade but looks like you're setting the template then trying to spawn another one?

[maiden plinth]

End Goal: Use the color of the material under my character to change the color of a blowing dust particle effect that is part of my character blueprint
What I am trying: Line Trace by Channel to ground directly below character. From Hit Component, Get Material from Hit Face Index (this is returning the correct Material). Then I have tried one of two methods for getting that Material to a Render Target; Draw Material to Render Target, and Begin Draw Canvas to Render Target -> Draw Material -> End Draw Canvas to Render Target. I then test if it has written things properly by Setting the Render Target Texture of a Material visible during runtime to the new Render Target texture and by also using Find Collision UV -> Read Render Target Raw UV (yes, i have the appropriate setting turned on for this to work). I have set all Clear Colors on my Render Targets to non-black to eliminate that as a problem.
Result of my attempts: The Render Target is only being filled with an all black texture.
Questions: What am I doing wrong? What am I missing? Is there an alternate solution to achieve my goal?

[lunar sleet]

Does your dust particle effect not use a material?

Why not just use a Mat instance and change the color parameter to match the color you want

[maiden plinth]

It does use a material, but I am trying to capture the color of the ground under the character's feet so i can then forward that color to the dust material

[lunar sleet]

You said that part is fine tho

The mat color is captured yes?

My point being do you need to use render target or can you just change the mat parameter on the particle directly

[maiden plinth]

it gets the correct material during the scan, but i am then using Render Target and Read RenderTarget Raw UV to get the color of the pixel directly under the character

[lunar sleet]

Ah I see

I’ve only worked with RenderTarget briefly but yeah I had all sorts of issues

[maiden plinth]

i simply am trying to get the color of the pixel at the hit location of the line trace

i feel like this should be super simple... especially considering it is done over and over with raytracing in a way

[lunar sleet]

Idk that the inner workings of ray tracing are simple heh

[maiden plinth]

well, not super simple, but what i mean, is that because raytracing exists, such a function to find a color at the end of a line trace should already exist somewhere in code and thus should be somehow available to get through a standard line trace

[sharp totem]

how would i go on creating a system where my master item class calls an id from a data table and gives the player the item? is it easily achievable with bp or do i need another system?

[hearty veldt]

depends on what kind of items and system you have in mind, but if you already have access to a DataTable, just store soft references to the items themselves, and when needed spawn them using AsyncLoadAsset

also nice

[graceful sage]

Is it really possible to use enhanced input to show a widget when holding input then removing when releasing?

I can't seem to get it to work correctly

[vocal ferry]

I did. I didn't realize you set the color parameters of emitters AFTER calling them, which feels weird but whatever, it works. Thank you

[raven gyro]

how come i can connect my material array but not my skeletal mesh? D:

[hearty veldt]

why not? where you got stuck?

[lunar sleet]

There’s a get linear color value function that might help you but 🤷‍♂️

[iron idol]

This is probably a stretch as it might be too specific of a problem. But does anyone know why calling this widget might be firing not valid?

[maiden plinth]

that is unfortunately a function related to color curves

[hearty veldt]

when you create the widget you need to pass in the PlayerController so it knows to what player it belongs to

[iron idol]

this is why i said it might be a bit specific. there is no player controller in this sense

it a turn based party rpg where the "Player" is ai pawns

so player controller wont work

[hearty veldt]

there's always a PC, even if you're not casting to a specific one, just do GetPlayerController

[iron idol]

Its unfortunately not my system, but i'm trying to figure it out and am at a total loss. Get player controller has not worked solving any problem in this project thus far, but I am more than willing to give it a try

where do you think i should plug get player controller into?

on setting widget in the second picture?

[graceful sage]

erm, I kinda got it all messed up now but basically sometimes it wont remove

Alittle confused on accuation time

[hearty veldt]

here's a quick, basic example, without many checks and bells and whistles, so it's easy to grasp, and then it doesn't matter if you call it from input, enhanced input, debug keys, it's all the same

[iron idol]

@hearty veldt In the "owning Player" pin?

[hearty veldt]

yeah

[iron idol]

yea, it doesnt work. I believe thats why there is the unit pin which comes from a variable in the widget

[graceful sage]

im specifically trying to get it to work with enhanced input

[hearty veldt]

disregard the 1st node, that's just something temporary till I have a save system, regardless if I plug the generic or casted version it's the same thing, however it won't work at all without it

[iron idol]

i get you but it doesnt work that way with this system

lemme show you

this is the same code but from a different project

remove from parent works in this project with this set up

I've replicated it exactly the same in my current project but do not get the same results

[hearty veldt]

what PC do you have inside the GM?

is it the default, blank one?

[iron idol]

lemme check

its a new game mode

not the base one

I do see that pawn is set to BP_FP so i do wonder if thats the reason

but i am unable to call the combat player controller from this pin and it isnt set up that way on the previous project which i sent an example of

[hearty veldt]

in my case it works regardless what PC it has connected to the node, just needs one

however it doesn't work if the GM has no PC assigned to it, the empty one doesn't work

this base pawn is not possesed currently?

[iron idol]

so what i'm trying to send the command to isnt "player" and there isnt really any possessing.

they are basically ai pawns that i give commands to

if that makes sense

so i think this system was not set up with a central "player" in mind

which is why i am struggling so hard to figure it out

[hearty veldt]

do you need that widget on every AI?

[iron idol]

yes essentially

like a jrpg for instance

it allows you to give commands such as attack

[hearty veldt]

but that doesn't mean they each need their own

[iron idol]

they dont have thier own

[hearty veldt]

you can just have 1 and move it around, change skills etc

[iron idol]

its a central widgit, my bad i misunderstood

in this example it works

this is from a separate project that used the same tutorial and i have confirmed that it is functioning

but yea, its one widget that just uses the variables of the pawn whos turn it currently is

just for ease of comparison this is the code where its not working

at a total loss because cross refrencing the projects, the code is essentially identical

[hearty veldt]

wait, I just noticed you call triggered and started

[iron idol]

not sure i follow

[hearty veldt]

triggered is called 1st, you create it

and then instantly started which removes it

[iron idol]

are you talking about in these examples or the other code above

[hearty veldt]

well doesn't seem to be here anymore

I opened it in browser cause text was too small and forgot to close it

but you removed it from here

[iron idol]

i'm confused? Do you mean an example i shared? I haven't removed anything

[graceful sage]

does anyone know how to have widget show will holding input then remove when release?

[iron idol]

haha, idk, thats not from me

[graceful sage]

because im trying different ways and was an old attempt

[hearty veldt]

oh

[graceful sage]

either it keeps adding and removing or it wont remove when i release the input

[hearty veldt]

I showed you the basic code to create it and toggle it

and it works just fine

I used the jump as an example

stays on as long as jump is pressed

you don't even need that cast to a PC when creating the widget, that was just for testing if both ways work, and they do

[graceful sage]

my issue is with the holding with enhanced input

i know how to do that.

[hearty veldt]

the jump IS on enhanced input in that video

you can see the name of the node

and the pins

[graceful sage]

okay so use pressed and released triggers instead of hold

[hearty veldt]

no idea what hold does, but if it's like Unity, then it's for long clicks or long touches

not holding down a keyboard button

could be wrong tho

a quick google says it's for mobile for long taps

I guess it can work if you want to do something like long jumps, usually in platformers you can jump higher if you keep the button pressed down for a bit

but if you say you just want to display it while the key is pressed like a map or score, you don't need it

[graceful sage]

its for a radial menu im just trying to display and remove that seems to work better.

[hearty veldt]

if it's something used often, just hide it, don't have it created and removed all the time, cause it won't eat a lot of memory, but will eat more CPU to generate and destroy, it's the same idea as pooling

[iron idol]

Not to interrupt you guys but I may have found a lead into my issue. I think I set some stuff up in game mode for the default controller instead do of my new contoller. not sure how fucked I am but you sort of lead me in the right direction of solving the problem so thanks for that

[hearty veldt]

was gonna get back to you and look through the images, see what's what

[iron idol]

hey, man no worries. Let me extend a thanks from the entire community for trying to juggle issues and help people. you're a champ

I might be able to handle it from here, or at least I see some differences in the two projects and that might be where the issue is.

[hearty veldt]

well I don't really see anything that could be problematic, besides not hooking any PC when creating the widget, which doesn't work in my case, but if you say it works in the other project

nvm, now it works for mine too

[iron idol]

yea, idk. I'm guessing theres a chance the issue lies with some code in the game mode and not what I have referenced

I think i might have an idea to what the issue is, but i'm just going to pretend that I'm probably right and call it a victory for a few hours before I let UE curb stomp me and put me my place again

sometimes you just gotta let yourself feel a little victory before jumping back in the trenches. 😂

[hearty veldt]

my guess is that something becomes null or not set to the active thing somewhere

maybe an unit, maybe the widget

[iron idol]

there are some casts to bp_fpc in my game mode which is problematic due to what i mentioned earlier about it needing to not run on default controller

i'm not positive, but when i cross refrenced it with my old project, the old one was casting to my combat controller

sounds like it might be a lead

eitherway if it is the reason, then even though you didn't directly have the answer, your questions lead me on a better path for solving the problem, so thanks.

[elfin hearth]

my solar panels meshs are following the sun rotation but for some reason my mesh is rotating at the opposite of the sun. I added rotator so it's pointing to the sun but it is still inverted when sun goes toward the ground, the panel point to the sky. Anyone can help? I'm looking for inverting the source rotation data

[tough creek]

Is there a blueprint node that can help with reseting a component attribute to it's default value?

I have some kinda bug that causes None values in both transform & static mesh.

Trying to create an actor action which resets the values back to their default.

[raw sleet]

Hey there! Is it safe to add variables to the Level Blueprint? I want a blueprint to detect which type of level we are in, to select different things

With safe, I mean, does eat up much performance or break the game?

[gloomy holly]

can anyone help me with this please?:

[fallen glade]

I'm looking for a better way to conform my meshes to a spline. What I'm doing right now is to get tangents from the spline and scaling them by the mesh length but the meshes aren't conforming perfectly to the spline, it can be better seen when different sized meshes are overlapped. Any other way to do this?

This is the spline in this case

Yeah ok I'm dumb I was normalizing the tangent vectore before multiplying it to the mesh length while I should have simply clamped the value

[waxen blaze]

Hi, is there please a way to create a timer in BP without a function or event. I noticed that using Set timer by .. nodes need a function/event input otherwise the timer doesn't start.
I only need a timer I don't need it for an event or a function but I can't find a way, please?

[versed sun]

what do you want to happen when your timer is complete?

[waxen blaze]

@versed sun Nothing.

I only need the fact that the timer is running.

[gloomy holly]

Does anyone here know how UVs work in unreal in regards to models and multiple UVs?

[waxen blaze]

I could setup a dummy function to run at the end which does nothing but it feels weird.

[versed sun]

Why would you want a timer that does nothing when finished?

[gentle urchin]

^

Or when looping

Otherwise just make your own timer

[waxen blaze]

It's a cooldown, I just check if it's running, if it is then I don't allow another function call.

[gentle urchin]

Capture current time on start

And add the cd for the end time

(Still you usually want an event to update UI etc)

[waxen blaze]

I see, that's a way to do it too thanks.

[waxen blaze]

Not in this case ;).

Thanks!

[gloomy holly]

Is anyone here got experience with UV maps in unreal engine, I've imported a model, it only had 4 UV maps, inside unreal I added more and copied them and changed their location, to represent player colours, but the UV maps don't seem to apply to the model, am I doing something wrong?

[versed sun]

sounds like a gate might be more simple @waxen blaze

[hexed cosmos]

hi guys, how can i fix this?

[undone sequoia]

Guys I have problem I have bombs on plane when I am throwing them i am detaching them from my actor and turning on gravity on them + adding them plane velocity sometimes happens that bomb is not falling even this process didnt fail but they will stay in the air , like stucked it happens maybe 2 times from 10 times idk what can be problem i printed all stats of bomb and gravity is activated and velocity added i dont know how to solve it

[brazen pulsar]

I'm not sure where I would even ask this, I'm trying to put in a minigame into my game- sort of an arcade shooting gallery thing that comes up in dialogue like in danganronpa- I have NO idea where to even start

[rotund barn]

if you are fine with loading screens it should be relatively easy. just load a new level which is the minigame

[brazen pulsar]

I'd rather not, I'd prefer to have little to no transition, just mid dialogue with a character when an option pops up that says 'I know you killed them' or something like that

[sour moat]

The camera component in one of my actor didn't show the mesh, I add a new camera in this actor and some other actors, only this one can not show the mesh. I did nothing in this actor, dont know why it happend.

[vital coral]

Anyone got any advice, tutorials to watch or documentation to read about how to get an AI dog to walk on a leash with a player?

[rotund barn]

i hope someone can give you a better advice, im still relatively new. but can you somehow pre-load the level, and then be able to switch to it with basically no loading times, just some kind of transition. im not sure i understand what kind of minigame you mean, but im guessing it would not be in the same environment right? also you may be able to just have a fully hidden room/area below the floor or somewhere near, and just teleport the player there. but that may not work if you need completely different mechanics that would require a different character blueprint

and to add, i have no idea if you even can pre load levels, but i think you should be able to. it feels like a very basic feature that should exist

[brazen pulsar]

I think if the level is small enough you can transition with basically no loading screen, but I’m talking more like the lockpicking mini game in Skyrim. Like a popup in the UI

[proud bridge]

I have a signIn level which is loaded on game start. When sign in is success, it uses open level function to open the mainmenu level. I m using AWS GameLift. When i use my command to connect to the server map from mainmenu level, the input is disabled, but if I use my command to connect to server map from the signin level, everything works fine. I m unsure as to maybe the problem is using the open level node? Both signin level and mainmenu uses the same gamemode. Can anyone help?

[crude pike]

In the material, are you using a tex coord node and changing the index?

typically you would change the Coordinate Index on the TexCoord node to determine which UV channel a texture should project to.

[gloomy holly]

I have this set up, but receive this error, I am unsure why

[crude pike]

Inside the material function, check that something is plugged into the Result output node

looks like it might be disconnected

[gloomy holly]

This is inside the material node

[gloomy holly]

You mean inside the UV selector material node?

[crude pike]

yeah, inside the function's graph, it looks like nothing is connected to its output

[storm solar]

I finished leafbranch's RPG tutorial series and I must of missed something.
There are two meele attacks setup that characters can do, one disables movement and the other doesn't and Im not sure why that is.
I checked the animation montage and the attack BP but haven't found anything related to movement or input.
Any suggestions on where to look?

[frosty ingot]

Can somebody tell me how i can stop my camera from twitching when jumping from one platform to another as seen in the last minutes of the video

[unique rock]

does any one know how to fix this

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Templates\Casts.cpp] [Line: 10] Cast of LinkerPlaceholderExportObject /Game/ThirdPerson/Blueprints/NewFolder/Player1.PLACEHOLDER-INST_of_Player1_C_2 to Actor failed

[wheat citrus]

There is a nice function to get a Random Unit Vector in Cone in Degrees which gives a uniform distribution of vectors (first picture). But there doesnt seem to be a function to do so with a normal distribution towards the center (second picture). Is there an easy way to make this happen? Im using this for bullet spread and I think it would feel better for the player if most their shots landed closer to where they were aiming.

[frosty ingot]

how to change the capsule component to make it more accurate to the character so the collision is not gonna act weird, but without scaling the character itself

[plucky quest]

If you go into the details of the capsule component look for capsule half height and capsule radius

[young meteor]

Unreal warn this node is expensive and I'm using it a lot at the moment.
Would it be way cheaper to get a variable that is an array of all the actors this node would find anyway? (So I would build the variable once in game instance and get it, but it would have the same amount of actors the "Get all actors of Class" would find)

[silent drift]

I have a weird thing, or maybe not weird, but I don't get it.

I have a character. The max walk speed is 800 cm/s, the max acceleration is 2048.0, according to my math to reach full speed it should take 0.391 seconds. However, when I do a loopable counter, I get to 800 in only 0.23 seconds.

What am I missunderstanding?

This is not crucial for my game or anything, I am just trying to understand how it works and such

[pastel garnet]

if the type you are looking for is dynamically spawned in the level then don't bother. but if it is preplaced in the level and you want to get all of them then storing it would be a good idea.
don't do it in the game instance, do it in either game mode or game state.

I might be wrong so if anybody could weigh in that would be great.

[mild jacinth]

hey

there used to be "fix up redirectors" option but now in ue5.4 i see "update redirector referencers". when i click the update one then should i press "keep"? is that equivalent to "fix up rediectos"?

[rotund barn]

what type of asset do i need to make out of a PNG to connect it to a variable in my struct? also what type of variable, there is one called image, but should it be object or class, and soft reference or not. i need will be passing that variable from my item to eventually into my inventory UI, where ill display it in a slot. its already functional so i only need to somehow get the image there

[stone field]

Probably a Texture

[rotund barn]

ah, it was a texture, but i was using the "image" datatype, but it seems there was also an option for texture. thanks

[stone field]

At least in the old version we have "Fix up" and "Fix up ( keep redirector )" - I always pick the one which doesn't keep

[wheat citrus]

Is there a way to restrict input on a macro? I want to make a macro that only compiles if both maps have the same key and value types. Is this possible or can I only throw an error at runtime?

[pine creek]

Can you square the vector components and then divide by the diameter of your target spread? I think something along those lines will pull a lot of the points in to the center.

[wheat citrus]

hmm yea that might work, thanks

[pine creek]

Can you do a "get" on the first index of each, the get class of those and see if the class is equal? It wont stop it from compiling but you could have a "is valid" bool output

[wheat citrus]

yea thats fair, was thinking of doing something like that but would have prefered to have it just not compile like with built in nodes

[pine creek]

something like this maybe? i'm not sure I follow exactly but this is my thought

or this if you mean keys A need to be the same type as keys B, and values A with values B

[spark steppe]

get first element of both and try to assign it to the same variable

connect that whole logic on the false logic of a branch which is always true

that way it might do the compile check without additional runtime cost 🤷

[wheat citrus]

Thanks for the inputs, seems like what im trying to do isnt possible anyways

for some reasons macros dont let you do wildcard logic, you always have to imply a type

[spark steppe]

no!?

foreach loop is a good example for the existence of a wildcard macros

[wheat citrus]

give me a sec I'll post a screenshot of the error

[spiral plinth]

Hello! I was wondering if anyone knows if its possible to modify landscapes in a blueprint component.

[dark drum]

Yea, there are no many unknowns. For example, if the two inputted maps have different key and value types it can't function.

[wheat citrus]

I mean yea sure but couldnt it just throw a compile error the moment you put those in instead and run if you put in two of the same?

[dry sleet]

Yes, it still fixes up the redirectors (updates the assets referencing the redirector). I tend to keep the redirectors because in the event we roll back an asset from source control for instance, it won't break.

[dark drum]

It's already throwing a compile error based on the rules epic has setup so unless you jump into C++ and edit some engine code I don't believe there's anyway to do what you're wanting.

[dry sleet]

Dynamically modifying landscapes is, I believe, one of those things you wish was easy but tends to be less-so :)

At least with ALandscape.

Could be wrong, I don't use it that much.

[wheat citrus]

yea I mean for my usecase I can just make it typed but I just wanted to create a macro to append one map to another so I can do it in other places in the future too, but guess ill have to do it over each time for each new map type

[mild jacinth]

Since the topic went slightly on redirectors. I have seen an issue happen now many times with structs, specifically that structs dont like being moved around to different folders while being referenced in other bps. Anyobe know of a way to fix this, rather than just creating a new struct actor with variables?

[dark drum]

Yea, macro can't even do this unfortunately. :/

[dark drum]

Save all, fix redirectors, save all again, move structure, save all, fix redirectors, save all again. Not perfect but it can help a lot.

[mild jacinth]

Believe me ive tried

5/10 times a bug happens where it causes unfixable redirector bug even after rebuilding from source

Packaging yields unknown struct error ("is the struct in redirectors list?") which is referencing broken struct

"Using fallback struct"

[dark drum]

Another possible cause if using source control can be when all the files aren't actually being pushed. Sometimes modified files aren't detected and never get pushed. If someone else then pulls, makes changes and pushes, you pull and boom, everything is broken.

[plucky quest]

I have a nav mesh in an area that goes through a door but when the door opens the nav mesh doesn't update so there's a line with no nav mesh where the door used to be, making it so the ai cant pass through the door. How can I update the nav mesh after the door is opened?

[quaint fable]

How would I store the state of my generators in the level blueprint?

[spark steppe]

you need a dynamic nav mesh

or at least one which supports modifiers

which you can dynamically place/remove when opening/closing the door

[hearty veldt]

don't use level BP, it's hard to access, you might forget it's there or you might need the same logic in another level, just store it on whatever object it is you want the generators to open, since they're directly related, and make the system self contained instead of having spaghetti mess

in general you don't really want to put stuff inside the level BP, there are some exceptions, but that's once in a blue moon, most of the time you're better off not doing anything in it

[plucky quest]

I was stressing over that all morning, thank you that fixed it!

[stone field]

totally agree. We opt to have an "BP_EntryPoint" in each level instead, working as the base of operations for launching the scene. Avoiding LevelBlueprints like the plague

[quaint fable]

Thank you! I figured out how to get these switches to work. I just made a for each loop that checks if all the generators have been activated. I used Get All Actors of Class, and if all actors of the "Generators" class are activated, then it shows that the gate is open.

The only thing I have running in level blueprint right now is a jump scare which only happens on that level. In the future, should I do what you mentioned instead? @stone field

[hearty veldt]

oh that's really bad, tick is bad, looping through literally everything is also bad, and looping through everything every tick is worse

[quaint fable]

@hearty veldt Is there a better event I could use?

[fiery swallow]

None of these are inherently bad, it's just bad in his case because he doesn't need it. Wanted to make sure that was clear

[hearty veldt]

like I said best case would be Interfaces, if you don't want that, at least do a direct reference to the gate, and keep track of opened generators, that way code only runs once when a generator is activated, and when all are activated gate opens

[fiery swallow]

Looping things on tick is fine, tick is fine, and looping through arrays is fine

[hearty veldt]

@fiery swallow oh, I didn't mean looping in general, as in that for each, I meant looping through all actors, just to get the ones you want, the for each only loops through a few so that's fine, it's everything before that that's bad, you can have hundreds if not thousands of actors in a level and looping through all of them is unnecessary, unless is done once on init, altho even that can be avoided

[spark steppe]

i wouldn't even make an interface for that

just link the generators to the gate

and notify the gate when an generator got activated

or add the generators to an array in the gate, and make an event dispatcher on the generator which triggers when they activate

[hearty veldt]

just for this no, but something for all sort of things that can be activated with a generic output, I'm sure a horror game has a lot more interactables than just this scenario

[stone field]

It's not like it's a total no no for messing around, but since you are grabbing direct references to the scene, it gets messy.

The idea of the EntryPoint system is not to control stuff like what happens in the game, say a jumpscare. The EntryPoint initializes the scene and ui as needed.

A jumpscare should optimally be it's own BP_JumpScare, something that you can re-use anywhere in future to trigger whatever your scare is for that particular point in the game

[quaint fable]

thank you!

[primal crown]

Anyone have an idea on how to like Vertex displace vertices in a triangle or well / using 3 points A B C

how would some one get animation play rate based on character speed

[sharp cloak]

Hello guys, is there someone here ?

I got a problem and i need a help

[spark steppe]

nah, we close at 8pm

[sharp cloak]

I cannot succeed to detect a collision between an actor and a brush box

[sharp cloak]

On the General Channel, they dont reply when we ask for help so ...

[spark steppe]

do brush boxes even have collision settings?

[spark steppe]

so no

then they also don't have a physics body, and therefor no collision response

you would need to use a box collision for that

you can most likely at some point (e.g. begin play) copy over the box extends etc. from the brush box to the collision box

[sharp cloak]

oh... but how to use boxes to make good sized texture on wall ? I used box brushed especially to make me able to positionate correctly my textures on walls ...

[spark steppe]

oO

[sharp cloak]

when i put a texture on a box and then i extend the box, the texture extends too

[spark steppe]

use proper uv unwrapping or make a material which does rely on world "UVs" rather than object UVs

because you stretch the UV of the mesh when stretching the mesh

a brush box isn't the solution to your problem

[sharp cloak]

oh ... so its very strange ... when to use box brush ? 😄

So, i need to make boxes in my walls to make a collision ? 😄

lol

😢

[spark steppe]

you should solve one problem after another

so either collision or texture first, decide

[sharp cloak]

collision

of course

[spark steppe]

for collision your mesh needs a collision body, which you can setup in the mesh viewer in unreal

guess there are some tutorials for that out there... on youtube or the unreal learning portal

[sharp cloak]

can you apply collision on brush ?

[spark steppe]

https://tenor.com/view/reading-stare-meh-sesame-street-gif-9636298

do not use brush ffs

if you want to create walls in UE use the modelling tools of unreal

[sharp cloak]

ok.. so i have to change all my level ...

[sharp cloak]

really ? how to do that ? Do you mean : modeling mode ?

[spark steppe]

https://www.youtube.com/live/3iIAcOtPJZg?si=3smykZ4h_dVJTzKt&t=2733

[high iris]

Got a little pickle here I could use help with. There's a variable in a BP class that seems to always reset back to null whenever I restart the editor. Doesn't matter how many times I tried to save it, make sure source control had it set, every time I open the editor I have to set it back to a value again. I hear that's a bug that occasionally some assets get into?

If so, any clever maneuvers one could try to fix it?

[sharp cloak]

Omg thank you for this solution guy, i learn another good tool in unreal 🙂

[sharp cloak]

Im going to rebuild my level with that tool, even if that will be long ....

[sharp cloak]

and to apply the texture well on the walls of Grid, how can i do ? 😦

[sharp cloak]

ok i think that will apply automatically correctly , right ?

[maiden wadi]

There is no cheaper way except if you already have them in an array somewhere. And this node is not inherently costly. It scales based on how many actors there are of the type that you return. Getting a few isn't really going to cost anything. Few dozen even isn't so bar. When you get into triple digits, it's time to start considering a registration system where the objects can register themselves to a manager and you can pull the array from there.

GetAllActorsOfClass pulls from a map basically of Class/InstancesOfClass. And iterates over them to dump them into an array of that type for you and return it. The most costly part of this operation is the array allocation. Smaller arrays tend to trigger memory reallocation less. Larger arrays need more contiguous memory to exist in, so as the array grows it can end up being move a couple times if the numbers are big enough.

So like pretty much anything, it depends on what you're using it for and the scale you need to use it on.

[lavish ore]

Hi, how do I set the "sound" value of the synesthesia, using blueprints? 🤔

So for example when the game starts it will select an audio wave variable and place it in the "sound" slot.

I have tried this. However, it won't let me change it.

[maiden wadi]

https://dev.epicgames.com/documentation/en-us/unreal-engine/audio-synesthesia?application_version=4.27

[lavish ore]

Only in editor? So you can't change it out mid game. 😭

Do you know any alternatives?

@maiden wadi

[maiden wadi]

Depends. Can you create one of these dynamically? Some things can be created dynamically as well as created in the content browser.

[lavish ore]

I will need some way to check the waveform of the audio, actually in game.

The synesthesia would be perfect if it didn't analyse the waveform before you play.

[rigid summit]

Quick question. How do I "Add distance" to a location? Gaol is a line trace from my gun to the center of the screen. I do a 1st line trace from the camera to the middle of the screen, then taking that impact point as the "end", start another line trace from the muzzle of my gun to that impact point. However, the impact point sometimes falls shy of triggering a hit, so I want to add some length along the location, how would I add math to that?

I tried getting a forward vector from my camera, multiplying it, and then adding it to the impact point, but it makes the trace off centered

[maiden wadi]

You don't really want to add to the distance so much. Not quite anyhow. You should use the camera trace hit/end point as a Target. Use the muzzle as a Start. With that you can use the... GetUnitVector or whatever it's called. This is a 1.0 length vector in the direction from your muzzle to the hit point. This you can multiply by some really large number like 100,000, and after multiplying that, add it back to the muzzle location

[rigid summit]

GetUnitVector is exactly what I needed! Thank-you

works great now

How to make box extent of a Collision box public?
If I turn a TriggerBox into BP the box extent is available to edit in the editor. I'd like the same for the Collision boxes I add in a BP.

[spark steppe]

you have to select the component in the details panel, then you should be able to edit them

how they are exposed to the actual actor for the trigger thing, is afaik only possible with C++

[primal hare]

hmm so I guess I'll stick to turning Trigger boxes to BP. Having box extent exposed is very useful

[spark steppe]

yea, or declare them in C++, it might be UPROPERTY(meta=(ExposeFunctionCategories="abc")) where abc is the category name that you want to expose to the actor details

[primal hare]

C++ is like swedish to me, can't even sauy hello

[surreal carbon]

hey is there any way to check if the user has alt tabbed or if the window is not in focus

[raven gyro]

any tips on how to make this into an array that reads all of the targets and materials?

[lunar sleet]

Are you looking for a Map?

[raven gyro]

the dynamic material instance can only connect one skeletal mesh target

is there a way to connect all of them into that ?

[lunar sleet]

Oh. Make array, for each loop, create dynamic mat inst

There’s probably a function to get all bones if that’s what you’re going for

[raven gyro]

well im doing a button to fade out all the bones except for the one that i pressed

[lunar sleet]

Yeah so if you can get the array of all bones, find the ones you want to remove from it, remove them, iterate over the rest

[raven gyro]

is this array correct?

then turn into this

[sweet imp]

Hey guys! I am trying to use navmesh walking movement mode for my enemies, but the collisions do not work with environmental objects. In the description of navmesh walking it says that if I have generate overlap events, it'll trace for collision, but even though I have this enabled it still doesn't. Unfortunately there doesn't really seem to be any documentation on this online that I could find, so if anyone here knows how to help I'd really appreciate it!

[iron idol]

been stuck on this problem for about 3 days now and unable to move forward in my project. Would appreciate it if there is someone on here can figure out whats going on that would be great. To summerize I'm trying to remove a widget from a party member in my turn based game. Despite the game seemingly knowing who the widget is attached to, it is firing "not valid" when I try to remove it as it says its accessing none.

the widget is set here in the image below within a funciton in the same component

I've had multiple people look at it and no one has been able to figure out what the problem is

[stone field]

If you debug step to the GET, what is the state of the "Unit Action Command Window" variable when hovered?

If it is indeed null, check that it is set correctly on creation. Then ponder sequence of events, or if the variable is cleared somewhere etc

[iron idol]

@stone field Not sure I've tried the apporach in your first comment? I take it I don't just hover over the variable?

[stone field]

You know how to debug blueprints? If not, it is time to start
https://dev.epicgames.com/documentation/en-us/unreal-engine/blueprint-debugging-example-in-unreal-engine?application_version=5.3

[iron idol]

I've used various methods such as prints and debug keys, but nothing beyond that. If this is somethign else entirely then I would love to learn.

[stone field]

Yes indeed, this is super useful to figure out why things don't work, and much more expedient than printing to console

[iron idol]

Would it be possible to bother you with an image example? I unfortunately learn better from visually seeing than reading

of the method you were suggesting

[stone field]

right click the node, add breakpoint, play until it triggers

[iron idol]

thanks

that summery might help

i appreciate your time

omg, I just realized this degualt value field had been blank this whole time

literally 3 days lol. The widget is still for some bizarre reasom is still not getting removed from parent despite not getting errors, but maybe this had something to do with it

[stone field]

locate the code which controls the current following system and start tinkering with it?

[frosty ingot]

thx lol

[frosty ingot]

i dont think there is any code related to any following system i just use a spring arm component

[stone field]

ah, I see

I haven't really used those for a while, but checking docs and setup first thing https://dev.epicgames.com/documentation/en-us/unreal-engine/using-spring-arm-components-in-unreal-engine?application_version=5.3

[iron idol]

You could maybe remove the spring arm all together and have the camera follow your character using vector?

like have a seperate camera entity. not one connected to your character/

[silent drift]

Hello! Anyone know if there is a way to make the character deaccleration slower? I tried changing the "Braking Deceleration Walking" both up and down, but I still go from speed 1400 to 600 in an instant. (I slide down a slope, fast and want to get back into my walk speed but not in an instant).

[grave relic]

Guys, I just need confirmation that what I did is going to work.
I have in my game a check that is done on the version number.
I have a JSON file on my WEB server.

In the game, I retrieve the JSON code then I compare it to check if it is strictly equal to the number that is on the server.

Since this is an offline game and I want to keep the game in good condition, I want to force updates on the client side. Which means that between two or more versions, I have a single file on the WEB server with the current version number.

Will the code I made below do what I want and not block or cause problems for people?

[versed sun]

what if they dont have internet connection ?

Request Not Success>Create Main Menu

[grave relic]

Yes, I thought about it, I know.
But with the Internet already, does it work?

[versed sun]

Looks like it would , just have to test it

[grave relic]

It was mainly the logic that I wanted to know 👌

Afterwards, I don't know if I block people without internet? Knowing that they are on Steam, I don't know...

[thin panther]

An online required single player game is a surefire way to guarantee your game's failure

[versed sun]

I wouldnt force an update on an offline game

[thin panther]

The joy of single player offline is not needing Internet or required updates

I get you want to deliver the best experience, but let your customers choose what they prefer

It hurts literally no one

[versed sun]

Unless they are competing for leaderboards or something

[grave relic]

Should I remove it then?

[versed sun]

just dont force it

If no interned > Main Menu

and , in Update widget , also option for Main Menu

[thin panther]

Personally I'd remove it.

Your platform handles forced updates anyway

You can make an update required on steam, with the bonus that people in the know can downgrade if they like

[grave relic]

In this case I change my loop to “False” and make sure to tell them that an update is available

In lobby?

Here

[thin panther]

Again, steam can handle all this for you, I'm not sure why this is necessary

[grave relic]

With SDK?

[thin panther]

No, by just pushing an update

[fiery swallow]

I think he meant using the steam sdk, so yes

with (steam)sdk

https://i.gyazo.com/6310642d984f693a8aef808d15c04d4e.png this 1

[thin panther]

No, you dont need to handle updating in game at all. In fact steam advise against it

You just push an update and you can't launch through steam until you update anyway

[fiery swallow]

ye steam has an sdk you use to push updates

you both right

[thin panther]

No it doesn't.

You use steam pipe to push updates

[grave relic]

I'm going to change all that.
I'm just going to make sure to add the update widget to the lobby. The player will only update if they want to. As long as it is on the current version, nothing is displayed in the lobby, otherwise, I just display a small message.

[thin panther]

Or the steam cli

[grave relic]

Yeah

Except I will use the Steam SDK for the next game

[fiery swallow]

anyway, you're both right

[thin panther]

Steam sdk has some pretty nifty things in it

[grave relic]

Yes I looked a little, but since my game is not necessarily online, I have planned that for the next one. We'll start on a complete basis with the Steam SDK

[thin panther]

Yeah definitely a good idea.
Though you'll still want the sdk for stuff like achievements

Or the subsystems etc.

[grave relic]

Yes, I saw that, I'm saving my magical ideas for next time

[vast vapor]

Hi ! I'm trying to migrate my pawn from using a FloatingPawnMovement to using a CharacterMovementComponent.
In both my BP I have an "Add Movement Input" node, that takes the same parameters and in my floatingPawn, the speed is capped as it should be and my character travel at normal speed

But on the other side my character won't stop building up speed...

I wish you can help 🥹 Thanks !

It seems that if I put a speed limit it actually won't pass it, but then my custom made acceleration systeme has no use.
I might say that I use the default flying mode in my CMC

[fiery swallow]

are you using a character class? or a pawn?

CMC only works with an actual character class

[gilded jewel]

hey all, has anyone seen anything either plugin or examples of a UI widget that displays analog controller feedback ?

[vast vapor]

I created a brand new character class

My old class was a standard pawn class with a floatingPawnMovement component slapped to it

[grave relic]

I saw a problem this morning while I was playing with the requests from the "Http Post Request" node, I just saw that when the request takes the output from the "Request Was Not Successfull" node, the game crashes and so does Unreal Engine .
I didn't say anything this morning, because there you go, but I have a colleague who has the same problem and even worse, when people play his game, on certain clients, the firewall blocks the request and crashes their game .
How can we solve this problem?

If you want to test add a fake URL and you will see your game crash, how can we fix this?

[stone field]

That seems very unusual. Engine version, any special use case, platform, can it be reproduced in a blank project?

stack trace would be good also

install editor debug symbols if it crashes editor

to get proper trace

[grave relic]

It's from the node, it's Epic Games who did something wrong in it...

[stone field]

no matter, show stack trace

[grave relic]

What? trace

[stone field]

1. go to epic launcher, pick your engine in Library, little down arrow, Options -> "Editor symbols for debugging"
   Then if Editor crashes, you should see proper error log in the crash window

[grave relic]

Yes i found

[grave relic]

Should I launch it right after?

[stone field]

restart editor, trigger the crash, copy the error log in the crash window

Wow too long sry

[stone field]

no that's fine

hmm

[grave relic]

It's only when the request is not made

[stone field]

I can see something in UDN related to 5.3 or less and WinGDK builds, not sure if related
Can you try it by setting default value of FWinGDKPlatformHttp::bUseWinHttp to true, or pass in runtime args as -UseWinHttpGDK ?

[grave relic]

Nothing could be simpler for it to crash, I put a URL as if I had made a typo by simply adding an extra m to url.com.
So it goes to the exit of the "Request was not successful" node and it crashes.

[stone field]

Also a post of something similar on Mac, but I guess this is on Windows

[grave relic]

That's to say?

[stone field]

no solid clues yet, just looking around

[grave relic]

Yes I didn't find much too

Because if my clients stay stuck like that, it's a shame.
And Epic Games isn't going to update, I think they have other things to do

[stone field]

well, this does look like a pretty nasty bug, surprised nobody else has stumbled on it if so... i gotta head out but might try to repro it tonight for the helluvit

[grave relic]

Yes sure

@ me

[mental thicket]

Hello - environment artist grappling with blueprints here. I've created a packed level artist with HISMs that provides some variation/randomisation to roof tile pieces on each run of the construction script (when the asset is moved or altered). Figured that out fine and got some nice variation going! My problem is that now I am attempting to give the end user the option to lock in and prevent further randomising via a boolean tickbox (RNG Frozen? in the screenshot).

Currently, when the user ticks RNG frozen, the blueprint will re-randomise once more before freezing further alteration. I need it to freeze it immediately, without that additional round of randomisation. I hope that makes sense. If anyone can advise if this is possible, please let me know. Cheers!

[old sonnet]

for default Character controller. Is thee a way to have character automove? like autorunner

[dark drum]

I would look at using random streams. This allows you to have the way it looks based on a number. (the seed) That way if you want it to look different, you just update the seed the stream uses.

[dawn gazelle]

It's an experimental plugin as far as 5.4.2 goes which means it's not ready for use and you really shouldn't be using it for anything that is going to be released.
The issue is with line 40 of HttpRequestProxyObject.cpp which appears to attempt to reference "InResponse" and call the function "GetContentAsString()" but if that InResponse is invalid (which it likely isn't if it failed to find the website in the first place) then it can't access that function which would cause a crash since the reference is null.

[mental thicket]

Thank you, I'll research random streams

[grave relic]

How can I patch this myself on the node?

[dawn gazelle]

You can't fix it within blueprints alone.

The only fix in blueprints is to not use this node.

[grave relic]

Yes but in the code of the node the C++

[grave relic]

How do I do it then?

[dawn gazelle]

Find some other plugin that provides HTTP Post functionality (there's plenty of them out there) or write your own.

[hollow tendon]

Cast to actor -> get the result actor and set it as a vatible.
use the new actor vatible and access its data.

the question is. Each time you access that actor which you casted to and settted it. does that consider as a cast when you access its data from the vatible that you set?

[grave relic]

How did you get the code here?

[dawn gazelle]

It's within the Unreal Engine source code, under Engine/Plugins/Web/HttpBlueprint/Source/HttpBlueprint/Private (as it states in the error message)

[mental thicket]

This took all of five minutes to research and succesfully implement, so I want to say again -thank you- for your help - this could have had me stumped for hours otherwise

[dawn gazelle]

A potential fix that may correct it could be as simple as changing it so that function looks more like this:

    FString ResponseString = InResponse ? InResponse->GetContentAsString() : "Invalid Response";
    OnRequestComplete.Broadcast(ResponseString, bInSuccessful, MoveTemp(CachedHeader));

This changes the function to check if InResponse is valid first before attempting to access the GetContentAsString function, and if it isn't valid then it'll populate the ResponseString variable with "Invalid Response" and changes the delegate to then use the ResponseString variable, which should then give you a correct response or "Invalid Response".

If you're not familiar with using C++ and finding errors or making changes to code and compiling, I'd highly recommend against using Unreal's experimental plugin as it's not ready for primetime if it crashes like this just because the URL couldn't be reached.

There's probably more landmines in the plugin if a glaring one like this is in there.

[gaunt stirrup]

hi guys

can anyone help me with a game menu mechanic please?

im trying to have my character select, song select, and map select depict which level loads lol lowkey having trouble

each mode select is in a different widget

im thinking , before you press play if i have a series of true/false nodes with the conditions of each mode it can sort which level you should be in

but im having trouble routing the conditions - how can i reference variables from other widgets?

should i make it all into one widget ?

[stone field]

One option is to use GetAllWidgetofClass

Or you might have some logic BP and the widgets talk to that

[grave relic]

I looked, I tried something else, it doesn't work. No need to rebuild or whatever? Just save the file and restart UE5 for the changes to take effect?

[gaunt stirrup]

do you know how i can do this

[dawn gazelle]

Do yourself a favor, and look for an alternative plugin.

[grave relic]

I already have Va Rest, is that good?

[dawn gazelle]

Try it out. See if it fits your usecases.

Probably more stable as it has been around for some time too.

[grave relic]

But I can't find an equivalent to Epic's node

[maiden wadi]

This sounds like a lobby. Make a lobby component or actor somewhere in your lobby map. Set selected state on it, Then all widgets have access to it globally.

[dawn gazelle]

Read its documentation for how to use it.

[hollow tendon]

?

[dawn gazelle]

No, casts only happen when they are executed. That said, casts are essentially "free" so it really shouldn't even be worried about in terms of performance.

[maiden wadi]

👀 Someone say casting was expensive again?

[dawn gazelle]

Assuming so based on the question 😛

[stone field]

nice catch : )

[maiden wadi]

There are some ways to do this, but I don't remember off hand. I know level instances are one. You stream them in when desired which async loads them. But there was also some new thing with 5.+ I think which allows you to do some type specific things to levels. EG hiding and showing decorations for different seasons kind of thing. Unsure if it's async or not though, but assume it is. 🤷‍♂️ Can't remember the name though.

[dry sleet]

Isn't that Data Layers?

I don't work with WorldPartition so I haven't explored them, but I recall that term at least.

[eager thicket]

is there a way to get a physics object to stay completely still until another physics object collides with it?

Set simulate physics on/off is ineffective for this task honestly

[gaunt stirrup]

wait what state do i set it to?

[maiden wadi]

The stuff you want it set to?

[hollow tendon]

cast is free? all this years i hear it is not free and it is in fact expensive. even a big devs here i remember from another server said it is expensive

such as @glad cloak, you or all this people who says it is expensive

so whom i believe

[glad cloak]

Huh?

[hollow tendon]

You once talked about casting in the past

and others too, in a way that might effect performance

so whom i believe now, is cast expensive or not

[dawn gazelle]

The act of casting itself is so cheap it only really factors in if you're casting tens of thousands of times a frame. The real "cost" of casting in blueprints comes from now having a hard reference to that other class that you're casting to in your blueprint, which means that in order for you to load the blueprint that has the cast in it, it also requires you to load the class you're casting to, even if you never reach the point of actually casting in your code, so it becomes something extra loaded in to memory because of a dependency. With enough casts being spread out through your code base, a single class could end up loading all sorts of blueprints into RAM even if they're not actively being used.

[hollow tendon]

you are contradicting your self Datura. what if you use casting in event tick

[glad cloak]

It’ll likely have an impact every tick but minimal in isolation, more of a death by a thousand cut things

Additionally can cause issues with dependency chains

[hollow tendon]

yeah

[glad cloak]

But every tick for one object is minimal

[hollow tendon]

so if it happens only once a second, it is fine?

thanks guys

How to add a function category? (Where you can store variable in a grouped place)

I do not see the option..

Secondly, is there a way to attach the CMC to a mesh inside an actor(on the z axis only)?

[pallid sphinx]

fixed it

[trim matrix]

So basically a way to change the CMC position

Without moving the entire actor

[quick rampart]

how to make score system for quiz ? i need a help

[rugged wigeon]

You just click into the category property and write a new one

[rugged wigeon]

The CMC does not have a position so that question is meaningless

[trim matrix]

I dont see that property tho

[rugged wigeon]

It is the second property in Graph under Description

[trim matrix]

Mhm then how would it be possible to attach the mesh(rootbone) to the cmc

[rugged wigeon]

it would not be possible

[trim matrix]

There must be a way... at the end of the day, its code

[rugged wigeon]

nope

what you're asking to do is completely nonsensical in the context of what these things are

[trim matrix]

Where is the setting to change the auto jump height? That maybe could fix it if i enter a big number

[rugged wigeon]

you would have to change the definition of these things in order for that to be feasible

what do you mean "auto jump height" do you mean "jump z velocity"?

[trim matrix]

The setting where when you only press W, the cmc can still go on it(without pressing the space bar)

[spark steppe]

step height

[trim matrix]

Im going to show to the problem clearly soon

[trim matrix]

this is what is happening... im not so sure how to fix that problem

@spark steppe @rugged wigeon

The cmc doesnt go up when the mesh does

[rugged wigeon]

the cmc is not there because the cmc does not have a position. it is not anywhere

you might mean the capsule collider

[spark steppe]

why am i not surprised by that kind of "screenshot" from you....

[trim matrix]

Yes, that's the correct name

[spark steppe]

the actor root is there

[rugged wigeon]

the cmc is the character movement component and is a different thing

[spark steppe]

and you moved the mesh up, relative to the actor root

[trim matrix]

So i should just setup the mesh as the root component?

[trim matrix]

I completly forgot.. thx for reminding me

[spark steppe]

you cant

the capsule is root afaik

you would move the capsule up

[trim matrix]

How would that be done? Since the control rigs is the one grabbing to upper stuff

[spark steppe]

https://tenor.com/view/feed-me-hungry-eating-spoon-full-bite-gif-14656605

[trim matrix]

Seems impossible to me lol

The control rig moves it... so i cant block it in the root capsule..

Ben, thx for your help

[rugged wigeon]

pretty sure the control rig just needs to move the root component of the skeleton and it'll move the capsule

[spark steppe]

i don't think so, but what do i know...

after all the mesh is child of the capsule, not the other way around

[rugged wigeon]

Yeah but that's just how root motion works, isn't it? The animation logic passes root motion, aka the literal motion of the root of the skeleton, back to the capsule? Idk, I haven't done much control rig stuff.

but that's the essence of what must be happening in a root motion montage

[spark steppe]

yea, but they didn't say that they use root motion

which may induce other side effects

[trim matrix]

I dont think im using root motion

Should i?

[torn kettle]

:question: should he use root motion?
:8ball: Outlook good.

[spark steppe]

that depends on your project

are there any built-in utilities for formatting blueprint code?

I have a strange bug. When I have a main menu level and I load the game level after a button pressed the player pawn gets possesed but the camera is wrong (You can see the character reacts to my input after eject from the pawn). I have a view from the origin 0,0,0. When I play in editor without changing levels everything works fine. Does anyobody has an idea what could cousing it? I placed the character BP directly in the world with auto possessing as player 0

[stone field]

Recommended plugins: BluePrintAssistant, NodeGraphAssistant, AutoSizeComments

[raw spindle]

Thanks, I'll take a look!

also, I've seen some people with different (straighter) wire styles - is that an option somewhere, or are they using plugins?

[stone field]

plugins also i believe, last i saw unreal doesn't provide out of the box.

one of those plugins has 3 or 4 different style options, don't remember which assistant

[raw spindle]

https://www.unrealengine.com/marketplace/en-US/product/electronic-nodes/questions?sessionInvalidated=true this one looks pretty nice

[stone field]

The main advantage of auto-formatting is just not having to waste time fiddling with placing the damn nodes

I love that, and try to enforce others to use it too so that bp readability is consistent

[pallid nest]

how does really the size map works? I dont understand why some of my blueprints in my size map has some actor components that I didn't add. It also happens with characters even when I dont have casting :/

[raw spindle]

love which? the plugin I linked?

[stone field]

no, I don't really care about the wire styles. I love having AutoFormatting, from Blueprint Assistant

[raw spindle]

ahhh ok

[trim matrix]

Is there a node to set the root component in BP like in cpp ?

can't find anything when typing "set root component"

[stone field]

If it hasnt been made into a node, you always have the option of making a custom node yourself to do it. It is not terribly difficult

[trim matrix]

Ikr, was just asking if there was one available.

[stone field]

If you can find the c++ function, and look at the header, one might assume that it has not been made blueprintable

[trim matrix]

And what if it has been made into a K2 function inside a statics/kismet library ? 🙂

That's indeed why I am asking if there is one

Anyway

[raw spindle]

https://www.unrealengine.com/marketplace/en-US/product/blueprint-assist is this the one you use?

[stone field]

I assume they are named intelligently, like "K2_SetActorRotation" and "SetActorRotation" so if you search for one you will find the other

[narrow pendant]

is there functionality to copy the contents of one enumerator to another? I have it referenced in a ton of places and I don't want to replace those, just replace its contents

[maiden wadi]

Why not just copy the enum then?

[narrow pendant]

because it's referenced in a ton of places and I don't want to switch it out

[cedar sparrow]

Is there any actually difference between macros and functions except that functions cant use latent nodes? Why would you ever use functions over macros?

[maiden wadi]

Which is why I said copy the enum. A Copy is a new class with the same values and a different name.

[trim matrix]

Macros are not available every where

[narrow pendant]

you mean copy like this, right? I'd have to replace the references to the old class then, no?

[trim matrix]

Macros dont have all nodes and are more complex to work with

[maiden wadi]

Functions and enums are entirely different. In reality you should prefer functions over macros just because of the general way that programming works.

Macros are nothing but a set of copy pasted nodes. They are basically the same thing as a collapsed graph more or less. They have minor uses, but they're not that great.

[trim matrix]

Enums?

[cedar sparrow]

Ah i see

[maiden wadi]

Only if you want to use it there? Your question now confuses me. If you don't want to replace it but want different values, you need to edit the enum you have. If you want a whole different enum with the same values you can use in new places, copy the enum.

[narrow pendant]

I want to copy all the entries inside enum A and paste them into enum B so I don't need to replace all the references to the class of B in my bp

[maiden wadi]

That I'm not sure you can do. Hand editing all the way. #DesignerLife

[narrow pendant]

alright thanks anyway

[maiden wadi]

Might be some C++ magic. But by the time you write it, you'll probably be done editing it.

[stone field]

can't debug step macros either, which is one reason i disklike them intensely

[lunar sleet]

Wdym by debug step

[stone field]

https://dev.epicgames.com/documentation/en-us/unreal-engine/blueprint-debugging-example-in-unreal-engine

[lunar sleet]

If you mean step through the code you can totally do it

You just have to know how

[stone field]

hmm, so is there a trick to it? do tell

[lunar sleet]

F9 on the macro itself, then step into

[stone field]

Thanks, will try it out next time I need to : )

[lunar sleet]

Least it worked last I checked

[trim matrix]

Harder than a normal fonction tho since the pin are weird in macros

[stone field]

I still don't really get why people would want to use them, except maybe to take advantage of the multiple out pins

[lunar sleet]

Yeah I only use them for that nowadays

[rare gale]

If I used Set Members in a struct, should those changes persist until the game is shut down? I'm having trouble with an Enum staying set using this method and not sure how to debug it

[gloomy holly]

does anyone know how to set a team number to random for a "setup player start"?

this is how i have my starting player setup, but it generates random team numbers for different models

[stone field]

as long as the Actor who owns the BP which holds the struct variable exists, it will remember it I think? Why wouldn't it?

[rare gale]

That's been my experience in the past so not sure why this is different. I create an array of structs from a DataTable and store that array in the Game Instance. I have a function library that has a short function to pull out the one I need (Ref, not copy) by array index and set members on that. I really have no idea why it isn't retaining that change

[maiden wadi]

Would need to see the function to speculate further.

[rare gale]

I'll put together some screen shots

[rare gale]

GameInstance runs this function to create the Array on Init... I know this works by printing the list on start

[stone field]

Not sure exactly what is the problem here, but I would start by cleaning up that flow into a more readable state, now it's a bit of stuff crossing over here and there. Not sure if the long green line from "Then1" works as intended if it is used in "Then0" either

[rare gale]

Component on an object the player can interact with in the world creates the QuestInfoBox widget and passes along the QuestListInt for the quests to pull from the Array in GI

[rare gale]

QuestInfoBox on init, creates the WListedQuest widgets and passes along each QuestIDInt

[rare gale]

On init, the WListedQuest widget gets the correct struct from the array and sets info based on its QuestState

Finally, back in the QuestInfoBox, when the button to Accept the quest is pressed, the state is changed and the UI is cleared. When I return to the quest giver and open all the UI again, the state is back to the original Active state rather than the changed state of In Progress

[rare gale]

I'm not changing this state anywhere else so I'm not sure what gives 😦

[rare gale]

Does set members require setting the referenced struct with the StructOut afterwards?

[stone field]

I don't see the SetMembers here

[maiden wadi]

I was about to say that same thing. 😄

I think you copied the wrong one last time.

[stone field]

I will open my project and check how we do SetMembers

[maiden wadi]

SetMembers works fine. But I'm 99% sure there's something else the matter.

[rare gale]

Wrong screenshot for the last one...

[maiden wadi]

Yep.

That is a copy.

[stone field]

Pass by value vs Pass by reference classic by the looks of it?

[rare gale]

In the function it is a Ref...

[marble tusk]

And it's getting a new copy each time it's called since it's a pure function

[maiden wadi]

You're getting it by ref. But look at the out pin.

Ref is diamond. Copy is circle.

So you're copying your ref.

[marble tusk]

Functions can't return by ref. Only the inputs can be

[rare gale]

Ohhhh, I didn't know that. So I can't do that as a function? I have to do the same thing each time?

Good info on the triangel vs circle... never knew that

How did y'all know that? Seems important 🙂

Well, that fixed it. Thanks a ton, I've been banging my head against this stupid wall for 3 days.

[stone field]

just looking around now to see if there would be a nice infographic on this subject somewhere

There's a ton of hidden stuff hardly anybody knows about : P

[maiden wadi]

Yesterday I learned you can drag a pin and just press R to drop a reroute.

[stone field]

yeah, tons of nice shortcuts and stuff which are hard to find

[maiden wadi]

I've been draging, drop, type rer, enter, rearrange... FFS

[stone field]

That said, with BlueprintAssistant I hardly think about all that anymore, just make the stuff then autoformat it

[gloomy holly]

well here is the issue im having

im trying to generate random player colours for each unit, but for some reason i am getting this result

here is the BP i have set up

[stone field]

I would try debug stepping through the code you have and figuring out what is going on that way

right now that last image, you create a material but don't use it for anything.

i can't tell from the screenshot if the final setMaterial is different for the 3, but I assume they are

debug stepping and/or logging tends to be the best way to figure out what is really happening in this sort of situation

[gloomy holly]

each material is for the UV's sets for player colours

[half sage]

hi guys, hoping someone can bonk me on the head and get me headed the right direction. Finally cracked ball cam with 6 degrees of freedom. Only problem is, when I introduce a lerp to transition between the views, it gets very wonky and jittery. First half is with it instantly cutting between camera modes, then I show my BP, then the second half is where it gets weird. Happy to answer any other questions about this, and explain any other logic going into this. Been stuck for a good minute.

[gloomy holly]

how do i do this?, i only started using unreal on sunday

[raw spindle]

echo arena remake? 🙂

[half sage]

add print screen and attach your variable to the output

[half sage]

Exactly

[raw spindle]

good stuff!

[half sage]

been wanting this on my couch for 10 years and no one is doing it

[half sage]

much appreciated

[stone field]

yeah adding print nodes is a solid start, but it gets tiresome in the long run. I would say it's never too early to learn to step through with breakpoints
https://dev.epicgames.com/documentation/en-us/unreal-engine/blueprint-debugging-example?application_version=4.27

basically you just add a breakpoint, play until it triggers, then you can inspect values and step forwards node by node

super helpful to really understand what your noodles are doing

[raw spindle]

Is there a way to export a timeline to an asset somehow? I have an old in-place timeline in one of my blueprints, and I would like to make it re-usable

[half sage]

would this work to inspect my lerp? idk if u saw my above vid, but the camera guys absolutely wonky switching to ball cam. maybe this would help me inspect whats going wrong there

[raw spindle]

looks like maybe the answer is no, but you can export the individual curves

[half sage]

you could call the same timeline in multiple places but I'd prefer to have separate ones for more control

[raw spindle]

Yeah I want to actually make it into an asset though

seems like you can only do curves

[stone field]

Possible, though time-related stuff can be clumsy with breakpoints. Still, to ensure the flow is correct, yes.

Usually when I have to debug something that happens over a period of time longer than 1 frame, I will leverage print strings more, but use breakpoints to ensure that nothing unexpected is happening

[half sage]

it's definitely when lerp is enabled which makes it tough. gotta be something to do with breaking gimbal lock i'd reckon. it's happy once lerp is done though even when inverting. real head scratcher

[stone field]

yarr, gimbals can be nasty

basically if you are using yaw pitch roll ( Euler ), you are going to die on gimbals

quaternions work better

depends a bit on what you are up to, but if you already suspect gimbal lock then thats probably what it is

there's always ways around things though, like if you show your case, can think of something perhaps

or learn quaternions, but that's something I'm pretty rusty with, havent needed to think about them for years

Add Local Rotation might save you perhaps

I think that uses quats

[gloomy holly]

im trying to set a "TeamColourNumber" for a player to recieve when a new player hosts or joins the server but for some reason it remains at 0 and is not increasing

[stone field]

you set it to 0 at the beginning of every pass through this function, which seems like it might cause the problem

[gloomy holly]

so this seems to make the colours change now

but on the 3rd player only 1 of 3 characters changes colour

[lusty hedge]

i have a very big issue with my game. when too many enemies are hunting the player through a nav link, they get stuck and push each other into walls

any ideas?

[stone field]

log the number being set for each char, will perhaps give you a clue

[marble tusk]

The only problem with the diamond pin is that there are some cases where a circle pin is still pass-by-ref. One example being struct break nodes

[stone field]

good to know

[marble tusk]

At least the blue colored custom struct break nodes. I'm not sure about the built-in green ones like break vector. Those might not

[stone field]

you probably need to make them a bit smarter : )
like if there's too many neighbours, figure out if you are not first in line to go, idle or backtrack a bit

[willow gate]

Hey guys. General editor question here. I'm experiencing an annoying issue where my gamepad controls the editor menus while I'm previewing in a standalone build. So I'll press directional controls on my gamepad and the editor will also focus on individual windows and even the close button often so that when I press the jump or attack keys on my gamepad, it'll close those BP's in my editor. Is there anyway to completely disable gamepad interaction within the editor? I don't use it unless I'm playtesting so I have no need for it to be able to manipuate things in the editor at all. (I found a joystick setting in Editor Preferences > Level Editor > Viewports but it didn't fix the problem).

[stone field]

perhaps this
https://www.reddit.com/r/unrealengine/comments/bmibsu/how_to_disable_default_gamepad_behaviour_in/

[willow gate]

Hmmm. I'll check it out but I doubt it. It's not just widgets. It's the editor.

[marble tusk]

I actually learned something new from this. I didn't know you could make compact functions in blueprint. I thought it was a C++ only thing

[wraith loom]

How do I turn off the collision of a component? "Set Collision Enabled" only works for primitive components, and I'm using scene components.

[maiden wadi]

??? Uh.. you can't have collisions on a scene component. Hence why it doesn't have the function.

For starts, you're in the wrong channel. And second before you go to C++, make sure to get the build errors and don't use the error list.

I feel you. 😄

[wraith loom]

Ah I thought my primitive components were scene components because I was able to add the primitive components to a scene component array.

[maiden wadi]

They are. Primitive components are Scene Components. But Scene Component has no idea about collision. It only houses location data. If you have a scene component array and want to set collisions for the primitive components in that array, you need to loop and cast each element to PrimitiveComponent and make your settings. This will skip over non primitives.

[frank sigil]

Im currently stuck with this error log saying that it Accessed none trying to read the components to my player character. im sure that its something to do with my character BP but i dont know how to fix it. any ideas?

[maiden wadi]

I don't think that error is coming from anywhere in your left screenshot.

[frank sigil]

It’s coming from my player bp

[limber parcel]

your components dont exist at the time your actor is spawned

[frank sigil]

How would I fix it

[limber parcel]

spawning actor components before the actor would be kinda silly, no?

you can fix it by using a delay (not recommended) or by using delegates

[frank sigil]

By components I was referring to like my character bp variables functions etc so would it be different?

I’m probably reading this wrong so forgive me

[limber parcel]

i cant see that function in the blueprint you posted

[frank sigil]

That’s the vehicle one

I can post my character bp if you want

[limber parcel]

might be helpful when the error is crying about your character blueprint

[frank sigil]

its a little scuffed in terms of organization but it should help

[limber parcel]

probably your car is spawned before the player spawns

[frank sigil]

its already there.

i use line trace to possess the car when I play it

[limber parcel]

it says your player doesnt exist though

[frank sigil]

and i read it wrong again

[frank sigil]

how do I fix it

[rotund barn]

what does this mean? "cannot parse value. property ENUMitems String: "NewEnumerator0" but i have no enumerator0

[limber parcel]

drag from the pin where u get character and search for "is valid" and add that to your code before using the character

[frank sigil]

thanks

[raven gyro]

is there any way i can tell it to use all indexes? instead of just one number?

[rotund barn]

for each loop, i think

[raven gyro]

i put it for each loop but it only register the last number D:

[stone field]

you can pull a foreach directly from the SkeletalMeshArray

but if you want specifically 0 to 16, that should really work. put a breakpoint there and step to check what is going on...

[lusty hedge]

sounds like i based my entire project on something too complex

[stone field]

let's see:
https://dev.epicgames.com/documentation/en-us/unreal-engine/using-avoidance-with-the-navigation-system?application_version=5.4

[radiant wren]

How do I make these variable folders like in the Motion Matching BP?

[lusty hedge]

i give it a read. thanks

[stone field]

r-click and add categories or something like that it was?

[radiant wren]

r-click isn't doing anything

[lusty hedge]

thats wizardry

[radiant wren]

er, well it doesn't have catagories:

[lusty hedge]

thanks ill give it a shot

[radiant wren]

ah found it, it's this:

[stone field]

ah yeah, wasnt r-click there

[raven gyro]

i tried all kinds of loop and not working QQ

[stone field]

use breakpoints and/or prints to debug and understand what is happening.
Perhaps the array actually doesn't contain 16 elements? Perhaps something else is going wrong and stopping execution?

[limber parcel]

by setting the category

[radiant wren]

Oh yeah I got it, thx 🙂

[tawny ginkgo]

I want to create a drive-able shopping cart, could someone point me to the resources that can help me understand how to create one from scratch? Thanks!

[sharp temple]

for some reason i can't figure this out but i have a random integer in range that goes into a append so it's integer to string because i this is for a mission in my game it appends the random number into the rest of my mission string and then at the end i have a integer variable to store the randomly generated number ready for the mission reward but yet for some reason the random number generated and used in the append is different from the print string of the stored value from the set integer variable first image is what the integer to string shows which is the Cosmic Points value for the mission and second image is the printing of the integer variable

[stone field]

get the random once to a local variable, and set that to the two places. Now each time it gets called it gives a new rand

[radiant wren]

So got another question and also felt this one to be best explained via video XD

[sharp temple]

will try that out now thanks

[thin panther]

Each wire off a pure node calls the thing again

[sharp temple]

even with a do once?

[thin panther]

One of the big reasons why you don't directly hook the result of a getactorlocation into a lerp

[thin panther]

Well you can't hook a do once to the pure node, so yes

Each wire is a new call to that pure node

After your do once, you have two wires from that random int, so that's 2 different random ints

[sharp temple]

i know but a pure node can be executed in the same line as a do once

only reason i am using a do once is because of the for each loop before it because it's adding the challenges in a list

worked like a charm thank you so much @thin panther and @stone field

blows my mind that it was is that small thing great thing to know now

[stone field]

Still a bit unclear to me what is the objective. If one rotates, the other should rotate as well? Why does the pivot have to change

[radiant wren]

So that piece is supposed to be a lever, I want the lever to rotate around its own center instead of around the whole blueprint's center

[sharp temple]

have you tried using blender going into edit mode and center it in edit mode

[stone field]

Optimally the model is created and imported with the correct pivot from the start. I've always found fiddling with pivots in the engine a pain

[radiant wren]

yes, the origin is where I want it to be in Blender, yet when I imported it, the origin was at the blueprint's origin

[stone field]

don't know why it's so hard, but then I never really dug deep into how models and stuff work

[radiant wren]

I made sure that "apply transform" was off when exporting

[stone field]

maybe just fiddle with the import settings until you get a clean item with correct pivot right off the bat

[sharp temple]

try this https://www.youtube.com/watch?v=RMjjOIO6LMo

[radiant wren]

OH that looks like exactly what I need, thx

[sharp temple]

np

[radiant wren]

heh... that's stupid... it's a checkbox XD

that is on automatically

[sharp temple]

it always come down to it 😄

[stone field]

Unreal Motto "there's a checkbox for that"

[sharp temple]

usually if everything is setup perfectly it should just work but nothing usually just works

[stone field]

it's been a subject of much discussion over the years
https://forums.unrealengine.com/t/how-to-permanently-change-the-pivot-of-a-static-mesh/279376/59

[sharp temple]

would be really nice as it has a lot of uses if you could just do it on the fly

[thin panther]

Fortunately you can bake pivots in ue5 modelling tools

[sharp temple]

you can do it briefly by holding i think alt+left click on the point of the model

[stone field]

aye the forum post has several angles of attack, but best is always to have them right from the start if at all possible, then resort to meddling

[radiant wren]

so..... now the mesh is gone XD

sigh....

[sharp temple]

is it just really really small? 😄

can you show the model in blender?

[radiant wren]

I mean... it is small..... but I've looked, it isn't there and confirmed by the content browser:

[spark steppe]

approx size 0x0x0

you imported at wrong scale

[sharp temple]

yeah it does just seem to be to small for the human eye lol

as confirmed by Ben

[radiant wren]

no it's exported correctly, cause when I import it with that checkbox checked it works fine:

the checkbox that applies the origin

[sharp temple]

what about the scale in blender because unreal engine can scale it different from blender if not setup correctly

[radiant wren]

seems all good on Blender's side:

[spark steppe]

1 blender unit is 1m

1 unreal unit is 1cm

[sharp temple]

should be 0.001 or something

[spark steppe]

no, your scene settings should be different

and use 0.01m in blender instead of 1m

or you import with 100x scale

which can cause other issues tho

[radiant wren]

oh....... I see....

XD

I know I once knew how to change the units in Blender but I've forgotten how

ah got it

[inner eagle]

Is it possible to populate an array during runtime with the .wav files that are in a folder (already imported into ue5)?

[radiant wren]

still didn't work but I gotta go now, will continue fighting with this tomorrow I guess XD

[sharp temple]

good luck come back with a fresh mind put things back to default on the import settings of unreal engine that you changes and tripple check blender

[radiant wren]

alright, will do, thx 🙂

[maiden wadi]

Sure. As long as they're set to cook and exist. There is an asset registry that has some functions you'll be looking for to get assets by path or whatnot.

[inner eagle]

Alright, I'm glad that you confirmed that it's possible, been stuck for 2 days on this now hah and started to question everything. Would you mind giving me an example of how this could be done?

[maiden wadi]

Something similar to this. Pulled it off of the forums.

There are a few different variations of those GetAssets functions.

[lusty hedge]

i added it 🙂

it was litterally a bool i had to check

they have the avoidance built into unreals movement component

INSANE

magic

the one enemy is still getting stuck on the window so i think its a different problem

[inner eagle]

Thank you, I've played around a bit with these nodes but haven't really gotten the result I want, but that's due to me being a complete beginner. My goal is to populate "WaveAssets" in my metasoundsource with the files added in the content browser in this specific folder.

Then I could during runtime change the integer (IndexYo) using UI buttons. The only step I have left to do this is to actually populate the WaveAssets array with the sound files. Please let me know if you have any direct solution in mind, I'll give GetAssets a few more tries!

[surreal bridge]

So, I am currently working on setting up an actor to dynamically create splines to other actors.

The splines will need to be having points along the circumference of a circle with a variable radius

The direction around the circle is dependent on where the target actor is in relation to where the current actor is facing.

For some reason, after all of that, I still have to change to the angle for the points on the circle. If it is rotated 0 degrees, I have to add 270, if it is facing -90 I have to add 90, but if it is facing 90 or 180 I don't need to add anything. Not really sure why

However, the issue I am having is that these will only work if the current actor is facing a cardinal direction because I have used a few float switches to get certain outputs related to the rotation.

I feel like I am overthinking some things and I would like to see if anyone can help me with this in the DMs

[dim halo]

if i wanted my ai to stop focusing on a target momentarily will it is attacking. is there a way to momentarily pause set focus if it is being used in the behavior tree

[paper smelt]

How would I go about setting a varuable from a child actor thing from another blueprint?

[rugged wigeon]

Set Focus is a one time operation, not something that is happening continuously. It does not make sense to "Pause" it. You might mean clearing the focus and then restoring it later

[rugged wigeon]

You have to call GetChildActor on the Child Actor Component. That will give you a reference to the actual actor.

[rugged wigeon]

I'm not really sure what you're trying to do but it sounds like you're trying to figure out if you should route clockwise or counter clockwise around a point based on some sort of faced direction rule.

You probably want to check the sign of some dot product depending on whatever rule it is you want to be doing.

e.g. if DOT(A's forward vector, B's right vector) is positive, that means A is facing some vector that is at least partially to B's right. And if it's negative then it means they're facing at least partially to the left.

[surreal bridge]

Yeah, I have most of it working, but it just seems like something must be wrong with what I am doing to have that odd issue with things needing to be rotated again.

I am mainly wanting to have someone look over what I have and see if there are any issues or any way to make it better.

[rugged wigeon]

well, try to use vectors to determine your rotation needs, not the current state rotation values, which have awkward issues flipping signs

I would advise against putting yourself in positions where you need to get the rotation of an actor to calculate logic. Almost always getting the forward/right/up vector will lend to simpler calculations

[surreal bridge]

Alright, I will give that a try. Though it's a lot to change so I will be rewriting it and avoid using the actor's rotation

[cold lion]

Hi does anyone know why my BP doesnt toggle correctly on each click? I have the same logic for the flashlight but this one takes 1-3 taps to actually toggle the speed?

[frosty heron]

Don't use flip flop and that will be an imporvement already.

issue with flip flop is that it remember the state, so you can't force alter the state when you need to

[cold lion]

oh okay
