rocky radish
hmm
i cant find the problem, if i see anything wrong i'll tell you
that's odd, i just redone the exact blueprint you did and it worked
copper elk
hmm
rocky radish
try maybe restarting the engine
rocky radish
is the parent visible or not?
rocky radish
try making another animation, but just copy the fade in animation and reverse the keyframes
and see if it works
rocky radish
well, i'm afraid i don't know whats the issue
copper elk
did you get the set visibility in the animation
rocky radish
yes
copper elk
o ok
rocky radish
try making the fade in object already visible and only run the animation when you click the button
and remove the set visibility
copper elk
wait a second
the button isnt connected to anything but the widget...
OOOO
I think I know what the issue is
rocky radish
ok
copper elk
ok so I have this weird thing
rocky radish
yes?
rocky radish
any idea where it could be?
copper elk
I dont press anything, nothing I just sit there and it disappears
hmm
maybe the same widget
I was thinking its the fade in animation
rocky radish
check where your remove widget nodes are
copper elk
where I have set visibility collapsed I was thinking that for some reason it would collapse the whole thing
rocky radish
make it hidden and see if it works
storm venture
anyone know what causes this spotchy effect? im using ray tracing
copper elk
the remove from parent nodes aren't interfering with anything
rocky radish
try just removing the set visibility to hidden node and see if the animation will play
cuz if it does, you can just set the image opacity level to 0
rocky radish
like
rocky radish
yes
copper elk
I already removed it long ago
rocky radish
oh
rocky radish
no problem
copper elk
I decided to set the Zorder instead of setting visibility
but the widget still disappears
rocky radish
only solution i can think of right now is making another widget for the fade out
rocky radish
well, if i can think of anything else i'm gonna tell you
copper elk
thx
also the disappearing widget has nothing to do with the anim, as it wasn't used and it was disconnected but the widget still disappeared

hello again all, iv been away for a few months
am i tripping or is quixel raelly free now for all unreal users!?
😮
that sounds like way to good to be true
is there a catch?
wispy zinc
Catch is that final product/render has to be done in unreal. So not for use in other engines or DCCCs
No catch from what theyve said if you're using in unreal, other than the obvious that you can't repackaged megascans assets and try to sell them as your own, or make a placeholder app to sell them.
Has to be in render, game, or app done in unreal

Not sure how best to word the search, I'm looking for a tutorial showing how to add a character to an FPS controller. I brought the RPGUI interface asset and it default character is a First person character, I wish to change that to a first/third person character but fist I need to add a character it
hoary silo
plush yew
This seems pretty roundabout but I'm trying to get the angle that my character is looking to either the left or right. Dot products are great but they're always positive. So instead I guess I could compare my forward vector with a right vector and check to see if the difference is over 90 degrees
Actually, that works pretty well. I just need to throw in an extra condition about angles greater than 180
sweet relic
@plush yew wouldn't the best way to do that comparison be a dot product though?
plush yew
Yes, but a dot product can't be negative, right? So if I look to my left 20 degrees then I'll get the same info as if I were looking to my right 20 degrees
because as far as I understand dot product just gets me the angle between two vectors, not a rotation to reach the other one
lyric timber
trying to build UE4 with Flex... help?
plush yew
It looks like getting a cross product could help since that would return a sign that would immediately tell me whether I was looking right or left but I've never worked with cross products
sweet relic
if you just need left/right and you dot-product the look vector against the right vector anything >0.5 will be looking toward the right
plush yew
yeah that's what I'm doing now and it's working pretty well I think I'll leave it this way
plush yew
contrary to what I just posted I'm somewhat familiar
either way we're going to need more information before anyone can help

so each time the enemy gets hit the timer will reset to idk like 5 seconds.
if hes un touched for 5 seconds then he will stand back up

how do you move multiple actors in sequencer?

add them to seperate tracks
they need their own transform track, possibly you can group/parent the actors to one dummy and use that as the transform track

@grim ore thank you so much for helping! 🙂
copper elk
@thin tendon you can add Advanced Steam Sessions to your project, and drag out a node called get player unique ID and off of that, just do get player name, connect it with some widget text and it will display the playername
I can send you some screenshots later during the day
But not rn sos

have anyone here implemented his own FFT water simulation ?
i am trying to do this tutorial https://www.keithlantz.net/2011/10/ocean-simulation-part-one-using-the-discrete-fourier-transform/
but the math killed me
cloud cobalt
Look up gerstner waves
alpine zephyr
gerstner waves is not easier. plus it doesnt look that good
cloud cobalt
I'm pretty sure it's easier than Fourier of all things
alpine zephyr
FFT look so real and all games now use it
cloud cobalt
Sounds like you're gonna have to either learn the math, or get an ocean plugin
grave nebula
@alpine zephyr Which part exactly are you having complications with ?
alpine zephyr
is the yellow part being multiplied by the exponent ?
and in pink is he multiplying the two summations or what he is doing exactly ?
cloud cobalt
The pink part is summing for all values of two dimensions
alpine zephyr
and in the other image where u expains the function of h
he wrote it in two terms so i am not sure if he meant to multiplies them or what
cloud cobalt
It's two sums, so you need to sum for all values of n, then do it again for every value of m.
grave nebula
You gotta familiarize yourself with basics of complex number and Fourier series as well as initial work by Jerry Tessendorf in that field, otherwise it will be a painful experience for you all along.
alpine zephyr
the other image he multiplied the function of height (h) by its h0 how can i do that in blueprints ?
cloud cobalt
This isn't going to be a Blueprint thing
cloud cobalt
I mean, Sea of Thieves's water is CPU-bound and i'm skeptical they did it in Blueprint.
grave nebula
no
alpine zephyr
how can u do it in general (from programmer perspective)
how can u multiplie h by h0.
if h0 is old h
so i am required to store h twice
Sea of thieve's is made using unreal ?
cloud cobalt
Unreal with a lot of changes on top
grave nebula
512x512 blueprint version runs about 10 times slower than compute, and is entirely bound by render thread
alpine zephyr
i know BP is bad. i generally like to do it in cpp
but as i am new to unreal i find BP is good to introduce me to unreal.
cloud cobalt
Implementing FFT ocean simulation is one hell of a way to get an introduction, tbh
alpine zephyr
hahaha.
i figured that out xD
but i am too committed. i want to make a pirates game
multiplayer one xD
grave nebula
@alpine zephyr It is okey. I was introduced to UE4 nearly the same way and been in your position some years ago. It is a good time to get yourself familiar with the topic instead of trying to mindlessly reproduce the code from formulas.
cloud cobalt
Did I already asked if your work could be on marketplace some day @grave nebula ?
alpine zephyr
well even if i fail which 90% i will. i would learn a many great things
grave nebula
Unlikely Stranger.
cloud cobalt
Well that's too bad 🙂
@alpine zephyr Basically my advice would be to start things really one at a time. Full ocean sim is not where you want your first step to be, just like you don't start space exploration with a Saturn V
And I wouldn't dismiss Gerstner waves either while exploring the topic
grave nebula
Yeah, there are quite a lot of alternative and easier approaches to start with.
One can get a quite decent ocean, even if mathematically challenged 😛
alpine zephyr
so where should i start. ?
abstract relic
Says the guy who managed to do it 😜
grave nebula
That does not dismiss the fact of me being mathematically handicapped. I failed miserably at math yesterday and few people here are witnesses. @alpine zephyr Start where every ocean starts, that being at GPU gems chapter 1: https://developer.nvidia.com/gpugems/GPUGems/gpugems_ch01.html
cloud cobalt
Do try various ideas too, from Wind Waker's ocean tech (which imho looks fine today) to the more modern implementations
grave nebula
I personally adore research work of Chris Wojtan and Stefan Jaschke in the area of water simulation.
alpine zephyr
that link is super awasome ! @grave nebula

what is this summation ? what i am summing W(X,y,t) about ?

@alpine zephyr It is a sum of all waves.
alpine zephyr
where do i get Di and Ai from ? are they randomelly generated?
and in (x, y) X wi what does this part supposed to mean ?
glacial pecan
level sequence has a playback setting "pause at end"... I can get it, but how do I set it? anyone know?
oh, I should have asked this in #blueprint
grave nebula
Di. is a direction of signal, denoted I. You set it somehow. Either directly, or as a function of i. There is no (x,y) X wi part. The part reads dot product of direction vector and position vector, and multiplied by frequency(wavelength) .
Likewise, Ai is either set explicitly or made as a function of i.
alpine zephyr
thanks again @grave nebula 😄
dim merlin
Hi, so is it common (and even possible) to fix a character z position to world offset on terrain?

i have a character that i want to switch between player control and ai control, what's the best way to go about this?
i'm trying to store the player's aicontroller onbeginplay but since its autopossessed by playercontroller and not aicontroller it's just lost from the beginning
or wait, can i like possess using the aicontroller class reference or something?
all im trying to figure out is how to possess by ai at runtime
so basically
how to possess a character with an aicontroller in case it gets unpossessed by the playercontroller?
@green flame you must know, please help me
dusky inlet
Deathrey,as someone who wasnt done much work in the field of GPU programming (did a Vulkan engine with cascaded shadow maps once, with some help, but that's about it), where would one start implementing more complex systems like these?
Is it just a complex material calculating displacement that you slap on a plane, or is it something you drill into the engine code for?
pearl sonnet
either way
cloud cobalt
@dusky inlet As far as water goes, the more advanced systems aren't going to be a simple material. It doesn't have to be engine code necessarily
dusky inlet
thanks, but I think I formulated my question wrong: what kind of object is going to 'be' the water? No matter where the calculations take place (c++, blueprint actor, material, CPU or GPU etc.) - is the result primarily used in a material's displacement node or is it not even a material you are using, or not a plane, or something else altogether?
cloud cobalt
Ah, sorry
Tessellated plane + particles AFAIK
But it's more than just displacement
dusky inlet
in what sense? Reflection and refraction etc.?
cloud cobalt
Well you probably want stuff like flow maps, etc
You could spend the next 10 years doing state of the art water rendering and not be that close to reality
dusky inlet
oh yeah definitely, I'm just wondering about the process
but that's good to know already, I sometimes see some UE4 tech art stuff with people I think of primarily as artists talking about buffers and the likes, where I think of low level frame buffers in gpu APIs, but they are talking about scene-to-texture capturing and the likes. So I'm never quite sure how complex the technical application itself is
cloud cobalt
There are many levels to rendering. People who talk of buffers and APIs are usually working on delivering rendering features, tech artists work above that and use the souls of rendering engineers to build nice-looking water
dusky inlet
lmao yeah, that's what I started to figure
ornate ice
People is it possible to rotate a child object?

@edgy halo gonna try that
Hey anyone knows how to print the range from 0 - 10 during a timeline length?
how to put it
like I want to display
every number from 0 - 10
in a timeframe
ahhh complicated to say
grim ore
so 0 1 2 3 or 0 0.1133 0.23344 0.34455 ?
grim ore
using a timeline?
ornate ice
yes
but I only want to use the timeline
for the time
not use the part of the actual function curves
so if my timeline takes 1 sec to run
I want to see all the values from 0 - 10
in 1 sec
if it takes 0.5 sec
they should be less spaced out I believe
so If I plugged in a rotation based on those numbers
lets say
0 to 90
grim ore
so if your timeline is 10 seconds every update it should print out the current time elapsed between 0 and 10. If your timeline is 5 seconds it should print out the current time elapsed between 0 and 10
ornate ice
in a timeline of 1 sec it would take 1 sec to make the full 90 deg rotation
grim ore
generally that sounds like you want a lerp
timeline is X seconds with the update outputting a float of 0 to 1 and plugged into a lerp for whatever you want between whatever and whatever
you can also map a range if you want
ornate ice
but I would have to keep modifying the last key frame to always match the time
right
I wanted to avoid that
grim ore
?
ornate ice
why you mean?
grim ore
you just wanted the values, what you do with that is up to you
grim ore
the timeline has a float track of 0 to 1 over time
grim ore
you can then just map your 0 to 1, or o to 100 % to any other range of numbers
grim ore
you have to have some form of track in there or else your timeline will go on forever
ornate ice
not exactly cause the timeline will only run for the time you set
but the track is not needed
thats my point
I want to get the same output of the track
without the track
grim ore
so you just want to start a timer at some point for some random amount of time and track it
you would have to modify the timeline to change the time so changing the end keypoint as well doesnt seem like much more work
grim ore
if you just want this to be a function instead that is variable then you would have to use something other than the timeline or modify the playback speed to adjust it with a variable
vast pine
Wut
Fresh dl of the engine and bam
Wish I was home to research it better this is my best current option
grim ore
@ornate ice if you did something like this, where the timeline track is 0 to 1 over 1 second, you can adjust the playrate before playing and scale it up or down to any other duration
@vast pine is this a fresh pull of the master branch or a version branch?
ornate ice
ohhhhhh @grim ore that sounds like what I need
grim ore
a lerp instead of the map range would work as well with 1 less thing to set up but the end results should be the same
plush yew
im trying to load unreal up and this keeps happening, can someone help please
grim ore
you will have to install the debugging libraries from the launcher (go to your engine version, click the drop down, options) so we can see what is actually crashing
plush yew
kk one sec then
grim ore
but seeing as how it's a video crash I would make sure your card supports UE4 and the drivers are sort of updated
ornate ice

copper flicker
@grave nebula that's what I'm worried about
that they simply do not allow AO with GI
cuz the new GI is supposed to be AO
except it's not..
it has some global effect, but locally there is no AO at all
I guess it only works with baked lighting?

nobody else has this problem??..........

have you tried on another pc

i have no idea sorry
you should report it as a bug

it's been already asked on the forums
timid jacinth
ah okay
copper flicker
I don't know about reporting bugs..
in my experience with Unreal, it's a waste of time
nobody works on those bugs
but I guess if it's a legit bug, they will figure it out
meanwhile I guess I have to go back to 23

You should be able to fade the audio source volume on a timeline.

cloud cobalt
@copper flicker Is it shipping ? Development ?
"Packaged game doesn't open" doesn't strike me as a typical engine bug
(Also it works for me on 4.24)
lone tapir
@sweet relic Hum, interesting! But unfortunately I still can't make 4.24 run on oculus quest.
vast pine
Rebuilding maybe something last run gimped
copper flicker
@cloud cobalt I added raytracing, and then removed it, and added GI, whcih worked
so I forced recompiling shaders a couple of times
other than that... same project
cloud cobalt
So is it a development package or shipping ?
copper flicker
what's weird is that the engine does not error during packaging
I tried both
both fail
😄
cloud cobalt
Cool, so what's the log from development ?
cloud cobalt
I mean, get us the log so that we can tell you what went wrong
cloud cobalt
Dunno how that would help you, tbh
cloud cobalt
No log, can't help
copper flicker
oh, nvm, his log link is broken
sorry about that
but he also pasted the log, and there was nothing obvious there
cloud cobalt
Saved/Log/ProjectName.log like usual
copper flicker
I already uninstalled 4.24 and wiped out the previous folder
oh, it was in Saved
it's dead
: <
sorry
cloud cobalt
I mean why even talk about your issue here if you just removed everything entirely ?
cloud cobalt
You'll have to go back to 4.24 some day and you'll have ther issue again, so...
copper flicker
and since I dind't find anything online, just that 1 guy..
not sure.. maybe they find the problem and fix it
in fact I don't really need 24, maybe 25?..
cloud cobalt
Pretty sure the problem is on your side :/
copper flicker
pretty sure it's not
cloud cobalt
You have 0 information on your own problem, so I'm not that sure 😛
copper flicker
I didn't do anything particularly bad....
cloud cobalt
That's not the point
I'm just saying "game doesn't run" is very rarely an engine issue
copper flicker
it's possible that something that was legit allowed...in 23 is not allowed anymopre
anymore
cloud cobalt
There are thousands of possible reasons
copper flicker
Stranger, if the engine packages without errors, and then the exe doesn't start, that's 100% an Unreal bug
cloud cobalt
No, that's nonsense
cloud cobalt
The packaging log is for packaging
If your game causes a crash immediately, it's not a packaging issue
If your game tries to use an asset that you forgot to package, it will also package fine and crash immediately
copper flicker
not sure if it crashes... it just doesn't start
cloud cobalt
If you package and give the game to a friend without the VS redist it will also not start
There are thousands of reasons
One of them is "engine bug"
copper flicker
no, there are no missing used assets
I have a few yellow warnings about missing assets. but they are not in use
and are not a problem for 23
uhm..... what do you mean about the VS redist?..
cloud cobalt
Anyway, I don't care if you think it's an engine bug. I'm just saying this line of thinking ensures you won't fix the issue if it's on your side
copper flicker
wait, so any unreal game that you ship you have to ship it with some VS package?..
it won't work standalone, without any extras?
I never shipped one so.. dunno
copper flicker
ok, so.. one can make an installer out of all this?
cloud cobalt
But you told me "if it packages and doesn't run it's an UE4 bug, 100%" so now I have doubts 😛
copper flicker
yes, it should be... according to my logic
cloud cobalt
Most people use stores, like Steam or GOG or Itch or... so the installer is not a concern
copper flicker
ok, so it handles all the extra packages?
cloud cobalt
It installs the things you tell it to

interesting
it looks like its in a release note going by the picture's url, have you consulted the release notes?
grim ore
enable the landmass plugin and look thru the sample content included with it
it's funny how you copy and pasted the part after "The Landmass Plugin provides examples of using Landscape Blueprint Brushes as well as a Blueprint called BP_CameraOverlap that can" rather than the entire line that tells you where it is
grim ore
I like how they are moving stuff to be self contained in the future rather than making people go back to the content examples to learn from (which most people forget exists lol)
normal burrow
what does that mean though? self contained?
grim ore
plugins can contain content as well as the plugin code itself. So when you enable the plugin and go into the plugin content folder you find the code for the plugin as well as example maps and blueprints on how to use it
normal burrow
ah i see
thats kinda lame though because you can't like delete stuff out of plugin dirs right?
i mean thats fine for engine plugins, yea nvm not really an issue there
grim ore
yep for engine plugins its fine and I doubt it would package the non code stuff into a final project unless you reference it directly

you know what would be neato, if the content examples had a change log

Hi guys, trying new 4.24 version, and got an info when trying to convert my 4.22 project:
ERROR: The platform name HTML5 is not a valid platform name. Valid names are (Win32,Win64,HoloLens,Mac,XboxOne,PS4,IOS,Android,Linux,LinuxAArch64,AllDesktop,TVOS,Switch,Quail,Lumin)
we are not using html platform...
any idea?
I know in 4.24 html is an extension but how to disable that info?
fervent sigil
@next badger got it. It seems decal size is not scale. I set decal size to the default (128, 256, 256) and used a different node to set scale. It's working - thanks!
next badger
it is size...in units, same as debug box
glad you solved it
fervent sigil
mm you're right; when changing the decal size in the level editor the size changes. but only when I used the scale in blueprints it worked.. weird, but yeah as long as it's solved.

Hi, can you import rigs into unreal engine from blender/cinema 4d?
abstract relic
Yes
runic iron
If you have some animated model in Blender make sure to apply all transforms, put units to meter and a scale of 0.01 in the scene's params. Then when importing in Unreal put an import scale of 100
next badger
it's not the rig...it's a skeletal mesh
runic iron
Also Blender adds a root bone with the armature name when exporting to fbx so careful if you do root motion
next badger
control rig is the tooling for animation
runic iron
There's a fix though for that, you can edit the fbx exporter to prevent blender from adding the bone. But only care about that if you use root motion

i need a box collision thats the same shape as the platform, what would be the best way to do it?
(basically i have items spawning inside a box collision but as the platform is curved they dont spawn on the floor)
vivid narwhal
can't you just use the collision data from the platform
nimble moat
Yeah im just unsure as to how, the collision on the platform is perfect
https://i.gyazo.com/803b5d4925050116738c9d6f2b2ba8af.png this is how im spawning items using box collision im just unsure how to transfer it over to using the platform collision

hello, for some reason if i import a skeletal mesh from Blender 2.8 and want to add a socket to it in UE4, the socket is very huge, what am i missing on the FBX export settings ?
abstract relic
You can just add the socket in ue4. Reimporting isn’t needed.
stoic moth
in UE4, it creates it as huge as in the picture
i never create the socket in Blender
but when ue4 adds it .... it's very big for some reason
abstract relic
Is scale proper in blender?
stoic moth
yes, those are the default add basic shapes
i just parented them to test a skeletal mesh
abstract relic
Not .001 or something yes? 😜
vast pine
So I take it alot people had trouble compiling datasmith?

@nimble moat bounding box is not the collision but you could choose points within a box above the platform, trace down from them and spawn where the traces hit the platform.
nimble moat
that would actually work, thank you!
hoary locust
how should i interpret a shader complexity like this?
tawdry lodge
does Hellblade 2 still running on UE4 ?
runic iron
@stoic moth I had some issues with scale when I exported anims. Maybe this fix will work for you too : before exporting put Blender' scene units in meters with a scale factor of 0.01.
Then when importing in UE4 choose a uniform scale factor of 100
@tawdry lodge I think they didn't communicate about the engine yet ?
stoic moth
ok will try
nimble moat
@spice canopy worked perfectly, thank you
runic iron
We'll probably hear more about it at E3, the announcement was quite short too but I don't remember seeing the UE4 logo

scale in blender should be .01

is centimeters, which is what you want for ue4

Hey everyone so I have a problem. Every time, I try and do anything in Unreal Engine (4.24) or any version, my engine just hangs then crashes
grim ore
@spark sonnet look at the Parse into Array node from a string
spark sonnet
Hmm that could work. Why didnt I think of that (: Thanks !
grim ore
@languid aurora it looks like it might be trying to compile shaders and getting stuck. Perhaps your firewall or anti virus is preventing shader compiler from running
languid aurora
I gave it permission get through the firewall
I haven't changed my antivirus. It just started happening all of a sudden it's quite odd. Suddenly this problem started
grim ore
it was just a thought. I think its lightmass that uses the network not shader compiler worker. if you expant UE4Editor in the task manager when that happens does it show the shader compilers firing up?
the other alternative is if you updated your GPU drivers recently. The latest Nvidia seems to be having issues with ue4
languid aurora
@grim ore I'll bet that's it! I did just update my Nvidia
Is there any work around for that?
spark sonnet
Is there a better alternative to switch on int? I got 1-60 integers :/
mossy nymph
always, but kinda depends on what you want to do
spark sonnet
I need to set a widget buttons position depending on the integer, or alternatively I can set visibility but doubt thats any easier
mossy nymph
or you can use a panel that positions them automatically
spark sonnet
Could you elaborate?
mossy nymph
there are different panels in UI
they each have their own way of lying out child elements
spark sonnet
Oh wait. I just found insert child at That could probably be used
mossy nymph
horizontal box will do it left to right, vertical top to bottom
spark sonnet
Its a grid of 5x12
mossy nymph
uniform grid and grid panel will take row/column coordinates
spark sonnet
That could work
mossy nymph
5 rows, 12 columns?
spark sonnet
yes
mossy nymph
for (i = 0 to 59) add child to uniform grid, set row to i/12, set column to i%12
spark sonnet
How would I do that in blueprint?
mossy nymph
literally like that
spark sonnet
Oh
mossy nymph
i assume you're creating the buttons as you go
(that was pseudocode, not c++)
you do a for loop from 0 to 59, loop body creates a button, adds child to uniform grid (which returns a uniform grid slot reference, from which you can call setrow/column)
spark sonnet
Do I need a new widget with a button?
mossy nymph
yes
spark sonnet
Ok
mossy nymph
unless you want to do slate in c++
mossy nymph
its the underlying system that UMG wraps around
i do recommend you expose on spawn either 2 ints for row/column or 1 int for index on the ButtonWidget
and connect those when spawning them, that way buttons will know their "address"
spark sonnet
I will
I just hooked everything up but its not adding anything to the grid
1S is a button inside the same widget
Is that the issue?
mossy nymph
yeah, no
you need 59 different button references
thats why you really need to spawn them
spark sonnet
Oh
mossy nymph
you don't use insert child at
spark sonnet
with which node do I spawn them?
mossy nymph
you use add child to horizotal grid, and to use it you need a horizontal grid panel in designer which is a variable
createwidget
mossy nymph
yeah, sorry
spark sonnet
but this still doesnt work
spark sonnet
Where can I set that?
mossy nymph
and call setrow, setcolumn
mossy nymph
index / 12 for row
index % 12 for column (remainder after division by 12)
a.k.a. modulo
mossy nymph
looks like it should work
spark sonnet
Its not showing anything
mossy nymph
provided shelf widget is actually something you can see
uniform grid is visible
and few other nuisances like that
pull a EventPreConstruct node
and plug its output into the for loop
that way you'll be able to see in designer the effects of what you're doing
spark sonnet
That did something yeah
Looks messed up but it worked
So why does that work but not the other way ?
mossy nymph
PreConstruct with branch checking for design time
is a good way to populate fake child widgets so you can see what you're doing
i have no idea what that for was connected to
spark sonnet
Its connected to an interface event that I know is working
spark sonnet
Stopped at all the nodes
mossy nymph
one possible explanation
you created that parent widget, called the interface event, then created another instance of the parent widget, without calling the event that ended up on top
spark sonnet
But this isnt an issue now. Now I actually just need to set one of them visible or to a different color depending on the 1-59 integer
mossy nymph
which button is different
spark sonnet
The button that should be different is the int I clicked on from a list
Its an array with 60 ints
mossy nymph
so you have an array of ints and a button grid?
horizonal grid -> getchildat(int) -> cast to button widget -> call event on button widget that sets the visuals (that you need to add to it)
also, stash the last selected int into a variable
so before you do that you can access the button that just stopped being selected in the same manner, then call an event on it that undoes the selected visuals
spark sonnet
The cast is failing
mossy nymph
yeah, that shouldn't happen
spark sonnet
Target is grid and index is the int
mossy nymph
index you got from... interface event?
mossy nymph
if the buttons are there at the time you call it
sure
i also hope you created those buttons only once
spark sonnet
I do
mossy nymph
or you'll have few layers of them one ontop of another
spark sonnet
But why is it failing to cast?
mossy nymph
i have no idea what you did there shrugs
mossy nymph
any accessed none in your message log?
spark sonnet
no message log
mossy nymph
would be something like accessed none trying to read property user widget from node cast to shelf in ubergraph <BP name>
mossy nymph
connect the output of getchildat to that print
at least get some useful information out of it
mossy nymph
so there is no child at that index when that is called
spark sonnet
I tried setting 1 as the index to but same result
mossy nymph
0 is the first one
mossy nymph
UMG has tons of stuff to watch out for, i probably won't guess it like this
spark sonnet
I get prints from both the int and the grid. And there is a child at that position
mossy nymph
got any other options for getchild?
spark sonnet
oh
Its got 0 children
I used get children count
So where are the children located then??
oh wait. I think I know why
mossy nymph
no clue, check from dropdown that lets you select instance to debug if you have expected number of instances of each widget
spark sonnet
Nvm
It doesnt have any children
But then I dont get where Im adding the children
Well. Thank you for your help @mossy nymph Its very much appreciated and I just have to figure out the rest tomorrow. Its almost 4 in the morning (: Thanks again!

So is the memory footprint of a given map based on the actors within the map and the assets those actors reference?
normal burrow
Define footprint
versed spear
well say I have a character that can change skins and those skins are referenced by the actor. Would all those skins be loaded into memory on map load?
normal burrow
Yes
Unless they are soft references
Think of it this way mattxor
When the actor exists, those things need to be loaded before they can be referenced
If your talking about textures though, gpu memory is different
But objects for these things will certainly be loaded
versed spear
So for instance say I had 3 class's a character could be. Would it be memory efficient to make these actors separate instead of having one actor that can be all of them? I see what your saying about the gpu textures could go in and out of memory as they are needed?
thin hemlock
Did the default C++ classes change? I updated my project from 4.21 to 4.24 and noticed when I created a c++ class it now has constructors and destructors
normal burrow
A texture object on cpu can exist without its texture data living on the gpu
Mattxor it is really up to you on organization but I don’t see the split up being super beneficial specific to memory usage
Soft Path/ Soft ref is the proper way to reference assets by path without loading them
Hakai created through wizard?
thin hemlock
Yes
versed spear
I am asking because I noticed the gpu memory profile has been going up as I add more skins. I will look into the soft path and see if it helps. Thank you p@t

I should preface that I chose none to where it’s just a default class, but I don’t recall default C++ classes having that extra fluff

As well as no F prefix

Ah yes None is a USTRUCT
Perhaps you meant Object for base?
You’ve got to pick it from the list

grim ore
have you tried debugging
copper elk
no
grim ore
why not?
copper elk
I did the same thing for on value changed but it still didnt work
grim ore
the first question is does that actual event work
put a print string in the middle of it and see if it prints out every frame something
grim ore
yep
copper elk
nothing
grim ore
then the event is not being called
go back to the text binding, clear it out and then set it back to that event
make sure to keep the print string in there until this gets fixed
copper elk
to the on value changed?
grim ore
just an fyi if you override the value anywhere, set it by hand, the binding will not work
grim ore
you have this event set to run every frame and to update the text in that text block right?
copper elk
binding yes
grim ore
ok you have 2 ways of setting it there
you need to fix it
you need to bind or you need to set, you cannot do both
copper elk
I removed the binding the number is there but doesnt change
Ik I connected this event just now
grim ore
ok so does the print string print out?
next wedge
@grim ore That was it, ehehe, much better now
grim ore
so now it's just the on value changed for that slider and when you slide it nothing prints out?
copper elk
yes
grim ore
maybe you have more than 1 slider or something else? I just tested and it should print out hello on each slide
every time you move the slider it should print hello even if the text doesnt update. if it doesnt then this event is not hooked up properly
grim ore
then your code is not correct somewhere
what does your designer look like for that widget?
grim ore
yep not worried about the text right now if your slider is not updating
do you only have this 1 widget?
copper elk
yes
grim ore
add another slider anywhere for testing in that widget, hook up the on value changed event up to just a print string, and see if that works
I can say that your code on the value changed should work, it worked for me in testing
and the on value changed is the better way to do it instead of the binding since it will only update when it changes
so your code is sound, something else is causing the issue
copper elk
ok sorry for the long wait
I was afk Ill try it now
It didn't work
the new slider doesn't work either
Ill try it in another widget
grim ore
if the new slider doesnt work your widget is fubar lol
copper elk
if there is an error in the widget but it isnt related to the slider will it still work
spark sonnet
Hey guys. Is there a way to add buttons to the grid in this order? I have a way now but its not placing in this order so im wondering if there is some logic I can change to make it

wild kestrel
you sure you putting right widget on the screen?
maybe issue is somewhere else?
@spark sonnet add children to grid widget in right order

if it's an ERROR and not a warning then no it will not work, the ERROR is preventing it from compiling any new changes

The grid is looking like it should but the positions are wrong
wild kestrel
what do you mean by that?
spark sonnet
I mean that they dont get placed from top left* corner ->
They get placed in another order
So integer 0 is not in the top left* corner
I mean left corner**

OOOOOOOOOOOOOOOOOOOOO @grim ore THX ITS FIXED
how can I make a slider only be able to go within a specific amount

so how can I set the minimum
