blueprint

[lofty rapids]

your pulling twice here

[sterile trench]

That was for the print string just to send screenshots here
That was my bad

[lofty rapids]

not just that

comming from the make

you have two seperate lines

this will also run twice

cache that value as well

befoer using the second time

[sterile trench]

I fixed it with the same results

[lofty rapids]

try fresh gets, don't use the set

[lofty rapids]

what happened to the second line, did you change it down the road ?

[sterile trench]

Spent 2 days on this and now have writing this again XDDD
Oh well, lol

[lofty rapids]

use fresh gets not the set

[sterile trench]

The second line was when I was testing it to see what's wrong
This was the original code (without the print string) and it was not working

[lofty rapids]

keep the print string

geez

you want the print strings

idk you need to fix that tho

but i see you think all hope is lost, this is usual

lol

[sterile trench]

Dude, I'm sorry if I seem difficult
I have a learning disability and sometimes it takes me ages to get things, lol

[lofty rapids]

thats fine

i'm not exactly perfect lol

but you want the print strings

but use the cache value

so that you can actually see what you ahve

before the pure nodes were causing it to look fkd

[sterile trench]

WHAT THE ACTUAL HECKKKKKK

IT STARTED WORKING AFTER RESTARTING THE ENGINE

I DIDN'T TOUCH A THING

somethings I want to kms while using unreal

[lofty rapids]

easy fix

but with pure nodes

it be like that

[sterile trench]

BTW, thank you soooooo much for being patiently helping me

[lofty rapids]

they run for every line connected to it

[sterile trench]

The pure node thing was just for the screenshots for our convo
I accidently plugged them in there instead of the variable I had right underneath it
It was still bugging out
But it magically started working after an engine restart

Anyways

Thank you ❤️

[lofty rapids]

i'm just saying for next time make sure you got accurate info

but ya a restart can definately help if things looks fkd

typically if things look ok and it's not working, the first thing to do is restart

[empty anvil]

I'm playing a muzzle flash particle in an anim montage but its positioning is off and for some reason changing the different offset variables here does nothing, how come?

[novel aspen]

do you mean that i make DataAssets at runtime and save them later? i'm not doing anything like that, just saving DataAssets in editor and then try to use them at runtime

[dusky cobalt]

but inside these assets do you have some structs or enums that you created in blueprint?

not on runtime just in editor enums/structs files

[novel aspen]

i don't have structs or enums in DataAsset, i have:

1. object references to assets (icon, mesh)
2. primitives

i also tried to use soft object references but it works the same

[muted gorge]

why i get Unknown from a value, I referenced everything

[dusky cobalt]

hmm, what are these icons btw?

[dusky cobalt]

this is how my data assets looks like

[novel aspen]

i guess plugin developer uses custom icons for assets

[dusky cobalt]

hmm okay, never heard of that

[jagged moss]

sometimes when I reimport a data table everything breaks afterwards and i have to reload everything. sometimes its enough just to reload the UI blueprint and the main character but some times i have to reload nodes too. is there a way to just reload everything at once?

[rose citrus]

How can I save a render target as a texture? I have a photo camera with a scene capture, and on input it captures scene. I can see the photo i took on a material with the render target, but how can I save that to a texture so I can set it as an image on a widget, and then take more photos and save each one seperately?

[frosty heron]

There is option to export to .png. You can then read the exported file.

I have an array of paths of all the saves image file.

[junior creek]

hi everyone!
I'm having trouble with my ragdoll + character movement. When using a physics handler to connect a ragdoll manny to the player, the original manny capsule (and collision) remains in place.
Is there an easy way to make it follow the ragdoll?

[frosty heron]

When you need to load the image just load with import as Texture2D

[empty anvil]

Could you not just disable the capsule collision all together when they're ragdolling or do you still need it?

[rose citrus]

oh it has to be exported? It is for co-op and I want everyone to be able to see the photo. Do the photos stay or delete when the game session is over

[junior creek]

I need it so another player can come and help carry the same ragdoll

[empty anvil]

You could always have your line trace (which I assume you're using to check for interactions, correct me if I'm wrong) hit the skeletal mesh itself and disable the capsule.

[frosty heron]

You cannot replicate an image file out of the box. There's plugin for it though

If you dont want to replicate , you can just call the function locally on each player to export and load.

However each player will not the same thing this way as everyone is running their own instance and there is delay. So picture taking a picture while everyone is running around. The likely hood that everyone sees the same exact picture is very low.

Coop or competetive makes no different here.

[junior creek]

Nice, thank you!
I changed the object type to Physics Body instead of Pawn and now I can regrab the mesh anywhere it lands
now I just need to handle the capsule whenever it is radgolled, but that is easy

[empty anvil]

Great, glad I could help!

[rose citrus]

What if I create a render target for each photo, say 10 max. for each photo I switch render targets, and then on the widget, I set the images to the 10 render target materials

[frosty heron]

You dont need to do that as you just save the snapshot that is taken to the disk then reloading it.

But for multiplayer the same principle applies. You will not see the exact same photo.

If you want to make it the same, you do have to replicate the image from the person that is taking the photo.

[maiden wadi]

Big data, much bandwidth, many bits.

[slow pumice]

Hello
When i create a function with some "for each loop" in a row. link with the "completed" pin.
Will the function stop and move on to the next function when the first loop is finished or when all loops are finished?
on my exemple, is the function 2 will get trigger avec the first each loop or the third of the function 1 (imagine there are some node avec each "loop body") ?

[maiden wadi]

The function will not finish until you explicitly call return, or your execution hits the "end". Which in this case will be the unhooked completed pin on your third loop node.

To be more explicitly clear. Function2 cannot in any way shape or form, no matter what you do, ever execute before anything inside of function1.

[distant grotto]

is it bad to pull variables forwards like this? From what I understand the only issue is that they might be out of date if later nodes are executed on a different frame

[heady terrace]

I did this yesterday and it worked. I was absolutely sure I tried this already, but I must have forgotten it or I was too hasty. Thanks @spark steppe

[slow pumice]

Thank you very much for these information

[heady terrace]

Hi Harvey, I was able to get this working after switching a few nodes around. Everything works. Thank you!

[steady night]

anyone got advice on how to Trace in a cone ?

like this *

[maiden wadi]

It's "fine". You just have to understand that the red node updates it's variables when it's called. So if you call it with Y being 1.0, start playing that montage, and then in the middle of the montage before your notify is ran, call the red node again with Y being -1, the notify will use the -1 value.

[lofty rapids]

probably with a curve

[spark steppe]

sphere trace and math to filter out wrong results

[steady night]

aye thats what i have in mind tbh

[atomic solstice]

Anyone familiar with arrays?
Trying to cycle through a bunch of levels but I dont know how to "add 1" to the Array Element output.

[frosty heron]

Use get, feed index + 1

You will also need to check if you hitting the end of the line, otherwise you will try to access index that is out of bound.

If index + 1 >= array length then do nothing

[astral mist]

Either with a series of line traces or you'll have to implement your own. Another idea would be to use a sphere trace and check the resulting objects are within the allowed angles. you could also limit per "height" as well.

I would go with the latter unless there's some very specific reason not to.

it's just obtaining the dot product between the normalized forward vector and directions then check that the cosine is larger or equal to the cone angle you want.

[vestal dragon]

so how do i communicate from a widget to a actor?

[lofty rapids]

what are you trying to "communicate" ?

the first thing you need is a reference

[vestal dragon]

a int

trying to have a cash var show in a widget but it changes from a different blueprint

[lofty rapids]

so you can do a couple things, you can bind it so it just auto updates to the value, or you can use events which is usually more efficient

[frosty heron]

The widget just read the cash variable from the actor.

[lofty rapids]

bind makes it so you just change the variable and it will update in the widget

pretty nice tbh

but i think it runs on tick

[frosty heron]

You can pass the reference of the actor when you initialise the widget.

After that its just getMyActor-> cash

[vestal dragon]

ok thx

@lofty rapids here is my code for it is this right?

[vestal dragon]

i used event

[lofty rapids]

does it work ?

it makes sense what you did there, got your cash value and passed it to the widget

[vestal dragon]

no

[lofty rapids]

check that the code is running with a print string

and check if your cast is failing if it is running

the image on the right

[vestal dragon]

well i cant bc its an interact

so id have to join as a vr

[lofty rapids]

oh thats a bummer you can't just test things

that makes the development process a lot harder imo

in order to resolve a problem, you need to be able to test things

[vestal dragon]

well yea but i can only really simulate

[vestal dragon]

could i do this but with a show/hide actor

like with a bool

[frosty heron]

A lot of bad things going there tbh

[vestal dragon]

oh

[frosty heron]

You dont want an event to call for money to update. You do that by binding delegate. The actor shouldnt need to ever tell the widget, hey do this

The actor should work with or without the widget.

One way depedency is important.

Your widget job is just to read.

Not being told what to do by other source.

This may sound not matter but it matters a lot, especially down the line.

If you are still struggling with blueprint coms i would slow down on multiplayer.

My 2 cent is to start getting familiar with event dispatcher and have the widget to just read.

[vestal dragon]

well i kinda have to do it for this whole thing

[frosty heron]

Condolences but all the best

@vestal dragon https://youtu.be/y4fE2JdFdvY?si=6jITCmu0pttEURAC

I would personally recommend this channel.

[lofty rapids]

I'm not sure what you mean ? I was suggesting to debug

[vestal dragon]

nvm

[vestal dragon]

ok thx

[faint pasture]

Sphere trace and filter by dot product

or just have a cone mesh and use it, depends on what you're actually after

Consider the small circles as the origins of the trace and the object. If you need this hit to be detected then you'll need an actual cone collider

If you're ok with that being a miss but this being a hit then dot product filtering will work for you

basically the dot product approach can tell you if the origin of a thing is in the cone, not if any tiny piece of it is.

[vestal dragon]

does he mention ui?

still just wanting to mainly fix thatg

[faint pasture]

It's the same idea

the UI should care about the things in the game world, the things in the game world shouldn't care or know about the UI at all

[vestal dragon]

oh

[faint pasture]

Instead of:
"Pawn tells UI to update the display for health"
it should be:
"Pawn broadcasts to whoever cares (dispatcher) that its health has changed, they can do whatever they want with that information"

that way pawn doesn't need to know or care if it has a hp bar, it just says "hey my health changed whoever is listening" and goes about its day

[vestal dragon]

well i got that code from a forum

[odd compass]

Does anyone know of a way to get the collision response that was triggered when a collision component is overlapped?

[vestal dragon]

so the should cast and NOT the bluprint?

[faint pasture]

wat

nothing is casting here

cast is not an action verb

it's not a "send"

[vestal dragon]

i mean the ui should get info and not bp

[faint pasture]

yes

[vestal dragon]

ok

[faint pasture]

I mean the dispatcher can be sending info but the important thing is that it doesn't know or care who's listening

[vestal dragon]

how would i do that?

[faint pasture]

you can add parameters to a dispatcher

[vestal dragon]

bc its supposed to updat when a player presses the button

it would show cash

[faint pasture]

you want "press button, widget shows how much cash you have"?

[vestal dragon]

no

its a vr thing it shows the cash you have when you press it

whitch is the point of an interact box

[faint pasture]

In CashDisplayingThingy:

Interact -> get InteractingPawn.Cash -> update display

make sure the thing getting interacted with knows who's doing the interacting so it can pull info from them

who being the pawn or playerstate or whatever

[vestal dragon]

thats the player info

[faint pasture]

ok so it sounds like you have what you need

[muted gorge]

is it possible to record every frame with any camera, it gonna be a item, as a hand recorder. (im gonna sleep, i can check 10hrs later)

[faint pasture]

probably hell no

You could do some stuff with video encoding etc

it's much easier to record the data used to draw that frame (objects and motions), that's WAAAAY less data than the video

[celest trench]

Does anyone know if it's possible to attach GPU spawned meshes to still rotate with a CPU mesh? Trying to have GPU only ISMs spin on the planet they spawn on
I noticed that if I spawn the GPU mesh it doesn't attach to the parent actor in the same way that spawning a CPU mesh does

[vestal dragon]

so whys it not working

[faint pasture]

Debug it, make sure everyone agrees on the boolean's state at all times

print it on tick

[vestal dragon]

well if the code is right how would ik whats wrong thats whats confusing me a lot recently, people would say my code is right but it still wont work.

i cant find what is wrong idk

[fleet prism]

Hello, I was following a tutorial to the T and I'm not getting the same result any help? The tutorial in question is "Unreal Engine - Grab - Move - Throw and rotate objects tutorial" by Qworco - Unreal Engine. By the 11 min mark he finishes the basic set up and Is able to move the cube around I am not sure what is going on did I mess something up or dose it just not work I did everything he did. Is anyone able to see what is going wrong and why its not working as intended. I've attached a short clip showing all my blueprints

[tiny tundra]

My fbx came in super-small and I want to change the scale. I figured I could just change this number but nothing happens. I tried hitting Reload after and still no change, what am I missing?

[graceful sage]

Have you done any print strings

[fleet prism]

yes, Only the trace function is working. nothing else seems to be getting an update

[graceful sage]

Is the bool being set true? What all have you checked/printed? Also I could be wrong but does the cube have physics enabled?

Been awhile since messed with physics handle

[agile loom]

Is this not supposed to be connected? (the struct)

[fleet prism]

I checked the trace function which is working, the grab object function which is not updating, the Marco for check below, and hooking everything up in the event graph in the First person Blueprint was checked to I only received feedback from the Trace function. and yes the cube has physics enabled. and I believe the bool is being set true, still a noob so I could be wrong in that regard.

[tawny hedge]

fighting hard with a Fill & Spill inventory mechanic, any recommendations for a tutorial or some info for best practices? I wanna avoid duping and stuff like that

[fleet prism]

He never connected it in the video and it didn't change anything anyways

[graceful sage]

So when you check for interface you have nothing selected

[graceful sage]

Do you have an interface implemented on the cube

[fleet prism]

yes

[graceful sage]

Ok so does implement interface you need to select the interface

[fleet prism]

you worded that weird but my interface is added to the cube now their is nothing in the interface blueprint yet because that's later in the video. But up to the ponit I am right now he is able to pick up the cube and move it around I am not

[graceful sage]

Im talking about the node on grab object function

Im on mobile and you posted a video or else I'd post the screenshot

[fleet prism]

no it wasn't I must of missed that bit. Thanks for your help and patience it works as intended now

[graceful sage]

Np

[fleet prism]

I'm a visual learner so it can be a bit hard sometimes

[crude hearth]

what's the best way to have settings in UE

like i want each settings to have a description a type and a name and i want to be able to save it and also cast to it and check it in runtime

[surreal peak]

GameUserSettings class is usually for that. Some stuff is also inside input related code.

I think Lyra has a GameSettings plugin that offers most of what you want

[crude hearth]

so i need to download it and copy the files?

[astral summit]

Guys, I have two arrays. One contains actors, and the other contains the integer points of each actor. The two arrays are identical in index. I used a sort node to sort the integer array in ascending order. Now I need to make the actors' index the same as the integer array. How do I do this? Is there a simple solution?

[dusky hemlock]

Why don't you use a map?

[astral summit]

The sort node cannot be used with it

[dusky hemlock]

why do you need to sort it?

[astral summit]

In order to place the players' points in ascending order in the UI

[dusky hemlock]

you could just manually sort them instead of using the sort function so you can swap both indeces with one operation

[tame pecan]

Have I been dreaming when I've seen you can change the class of a component in a child class like in C++ FObjectInitializer::Get().SetDefaultSubobjectClass<MyCustomComponent>("ComponentNameToOverride")

but in the BP menu

[dark drum]

How many elements would be in the array? (Roughly on the top end)

[frosty heron]

If you care about the order you shouldnt use map.

[lofty rapids]

there is even a sort in bp ?

probably a custom sort node would be better

where you can sort by value and it sorts the keys

[errant prism]

Hey, are there any people in the community that work with vehicle integrations, mainly the vehicle template from unreal ? Hope I got the correct chat category to ask 😄

[astral summit]

There is no limit to the elements of the array

[astral summit]

What do I use?

[frosty heron]

Array

[dusky hemlock]

you didn't read the original message

[frosty heron]

You dont sort map though because index is irrelevant

[dusky hemlock]

.

[frosty heron]

If you need the index then dont use map.

W.e the use case is.

[astral summit]

I have two arrays. I want to sort the points in ascending order, and sort the players with the same point index

[frosty heron]

If he wants to sort then map still irrelevant.

[astral summit]

Is there a picture of the solution?

[frosty heron]

You have trouble sorting or whats the issue?

[lofty rapids]

whats wrong with arrays ?

[frosty heron]

When your sort condition is met, store temp value to swap the index.

[lofty rapids]

and is there is a sort in Blueprint ?

[little agate]

i would just create another array of int and sort it, assuming the array content is the array index of both array

[lofty rapids]

must be custom ? or did they add it inew version ?

[astral summit]

Yes, just for intger array

[frosty heron]

Sort your self manually, create a new array / temp array as the sort happend.

Look up bubble sort if you need starting point.

[lofty rapids]

custom sort would be best you can sort both arrays at once

[astral summit]

I think it will be kind of complicated,

[lofty rapids]

it is

[little agate]

just make a struct and merge the data into single array god damnt

[astral summit]

Can you send an illustrative image?

[dark drum]

This with a custom sort function would probably be best.

[astral summit]

I feel like it's the best solution, but I still don't understand the method

[little agate]

bubble sort

[lofty rapids]

https://youtu.be/TLW757acOG0?si=xegynqfrpABlpxRq&t=324

[astral summit]

This manual method, to sort the array, I thought there was a shortcut

[lofty rapids]

well sort is built in, that would be your short cut

copy that and make it custom to your own needs

but like mentioned instead of two arrays, an array of structs would better

so you only have to sort one array

[astral summit]

Even if I use an array, a structure, there is no quick way to sort it, copy the custom function every time in another project, this is tiring

[lofty rapids]

make a BFL, called tools that you can migrate to your projects

it's pretty simple, no copy/paste

sorting wasn't even built in untill recently

you had to use c++ or a custom sort function anyway

but a function that you pass the two arrays, sort the numbers, and alter both arrays as long as the indexes match up would work

or even a manager actor with functions on it is ok, but the bfl is nice imo

[lofty rapids]

you may be able to get away with sorting a string array that is formatted properly as well

so instead of making a sort function, you just alter the data a bit

either way its some code and isn't that simple

[little agate]

it is just 1 step to avoid future bad data structure design I guess, worth a try. I wonder why ue doesnt have generic utility for this like making an interface with bool compare(Actor a, Actor b) and let the actor implement it, so we can sort any actor with custom comparator

[muted gorge]

is the problem getting every frame and save it
or
recording it with a own camera of item;

I mean, it cant be a record from the hand, i want a item that records the video when you have the item in your hands and press the spesific key

sorry for latency, i was sleeping

[lofty rapids]

you want to "record" every frame ?

[muted gorge]

capture

[meager spade]

Not sure if I missunderstand you but this exists, sort of. Nvm I did missunderstand you 😄

[little agate]

No, you probably right, actually i am new in unreal dev, lol

[meager spade]

No I didn't read your entire post, you are talking about creating your own sorting predicate right? I just zoned out at creating you own compare nodes which you can indeed do to achieve pretty similar functionality to operator overloading

[little agate]

yes, it is common thing in programming to have custom sorting predicate, and just create a generic sorting utility to handle all kind of sorting needs, not sure if unreal have this, that is why i wonder it

[sand shore]

What do you mean built in?

[meager spade]

I've never bothered trying to sort stuff in BP, that was the reason I started doing stuff in cpp to begin with

[lofty rapids]

i mean in blueprint isn't the sorting nodes new or they have been there for awhile ?

[sand shore]

I hadn’t seen anything about them

So they must be new(ish))

Aside from like Sort Ints or Floats

[meager spade]

In cpp you have Algo::sort() where you can give a predicate at least

[little agate]

I mean blueprint utility

[tawny shore]

Hey! I'm facing a problem. I made a Main menu widget,everything works fine,except the Play button. When i press on it,the level doesnt load. Here's some screenshots about the level blueprint and Play button graph

[lofty rapids]

does the event fire off ?

put a print string at the begin, does it say hello when you press the button ?

[tawny shore]

when i press play in the editor,i can switch between the main menu,settings,credits,etc.. Only the play doesnt work

idk

[lofty rapids]

so debuggin is something that really helps narrow down the problem

and the first thing i would do is check if the play event is firing off

basically when you have a system that has many parts, you need to narrow down which part is the problem

another thing is i'm not sure the code after load level will do anything if it works properly

[tawny shore]

ima check again at the main menu graph,maybe the level bp has something

[loud tree]

Well one thing I notice, probably isnt THE problem, but you're not actually focusing on the widget you're creating.

[tawny shore]

So i got it 😄 The default map was the "Untitled map",and in the Open level i wanted to open the same level,so thats why it wasnt doing anything

[muted gorge]

my tab key input action (it is input action) does not work on client, but it works on standalone and listen server

[dusky crane]

Is there a way for me to check from which graph a specific function got called when using breakpoints? i have a function which gets called 8 times instead of just 1 and i dont know what could be causing it 😅

[muted gorge]

use blueprint debugger

window bar > Debug > blueprint debugger

and then call stack

[dusky crane]

Thank you so much 🙏 it was a rogue debug function i forgot to remove after i no longer needed it

[muted gorge]

no probleem

[sonic spruce]

i need some help with blueprints, its not making sense to me. Does anyone know why this works

but this doesnt

like it prints the on / off strings, but doesnt actually deactivate the PortalCamera

Whereas in Event begin play it works just as expected

[lofty rapids]

any errors ?

[sonic spruce]

no errors

just fails silently

[lofty rapids]

the worst kind of fail lol

[lofty rapids]

and this is the same bp ?

[lofty rapids]

i think you want to clear on the endoverlap ?

atleast to match your original code

you didn't clear when you set active in the begin play

[sonic spruce]

yes, same bp

[sonic spruce]

the clear is just cosmetic, i have a bunch of portals in the map that need to be optimized

if i turn the portals on, framerates drops from 60 to 30, the clear is only there to visualize if a portal is on or off ^^

[lofty rapids]

yes render target is tough on fps

do you need it live ?

i see so your trying to turn them on when you overlap

so they are not always on

makes sense

[dusky cobalt]

Try to print on tick if it’s enabled or disabled. Also this actor overlap you didn’t specify what thing should overlap it or stop overlap so anything can be triggering it. Grab from other actor and check tag or anything if it matches, then turn on and off. @sonic spruce

It means that even floor might cause overlap or not overlap and it’s just getting confused maybe ?

[icy jacinth]

How can I adjust the parameters of a MI when it's applied to the brush of an image component in a widget? Most everything I've tried is causing the healthbar to appear distorted in the HUD. The parent maerial is set to UI and no textures are used

[sonic spruce]

hm, if everything would trigger the overlap, i think id get spammed with the print statements, but they only appear when the character overlaps

[lofty rapids]

i use collection parameters

but your saying the settings work, but they are just not working correctly ?

what does the material look like ?

[icy jacinth]

The material is pretty identical, with the exception of the shear applied in the widget. adjusting the parameters in the material show everything working as intended, but when I try to adjust the parameters from the widget (the blueprint in the original message), it causes the distortion with the segmentation 🤔

(I should say, I can't figure out quite how to adjust the parameters in the first place - but trying to create or get the Dynamic Material Instance for the image causes the distortion. I'm not sure if not being able to change the parameters is related or separate)

[astral wyvern]

Hey I'm trying to animate a widget in an out the screen, but the size of that widget can change. So right now, sometimes part of it remains on screen, takes longer to get to screen, etc. I tried relative transform animation but it's not working. Any ideas?

[vestal dragon]

@faint pasture so I decided to bind it but now it’ll stay at 0 even when the player presses the check money button. Should I try making it each tick to update the text?

[violet bison]

how to make sound cues fade out?

[surreal peak]

#audio

[lofty rapids]

so basically you create the instance through bp, you create dynamic texture, then promote to variable

this way you have a reference

then you set the material to that instance

and use the variable to change the parameters

[icy jacinth]

Ahh, I think the 'create dynamic texture' is what I was missing. I'll give that a shot once I can - thanks as always for the help, engage!

[lofty rapids]

you should also be able to just use the instance and set them manually but to dynamically alter it use the reference

[shell lance]

hi guys, just came across this video, and it left me confused. Should delay nodes be avoided? Should we always use timers in production code?
https://www.youtube.com/watch?v=KUYRBPagAY8&list=WL&index=10&t=44s&ab_channel=DoppelgangerStudios

[sand shore]

I’m not watching all that, but the answer is always “know the behavior of the tool in your toolbox; it depends”.

The main quirk of Delay is that you might expect it to be 1:1 - if you call it 5 times on a frame, you might expect to get 5 callbacks on one frame in X seconds. That’s not the case.

But delay nodes are timers under the hood

[dire trench]

Yes use timers in prod code and make sure to clear them or you'll get mem leaks

Less control, you cannot end a delay the way you can end a timer

[sand shore]

I would also say that if using a delay seems unintuitive to you, that is plenty of reason to avoid it

[shell lance]

but in a lot of cases there doesn't seem to be any disadvantage of using delay?

[sand shore]

A strict rule you follow 100% of the time will likely mean you spend an excess of time working around your choice

[shell lance]

I mostly use C++ and we have to use timers there, but I guess delays are fine for simple logic in blueprints?

[sand shore]

I see delays in production quite a lot

I also convert delays into event driven patterns sometimes

[shell lance]

yeah I'm just trying to get the pros and cons, no strict rule here

[leaden shale]

Hey everyone, I've been having an issue in which my assets, when switching, are snapping from the top instead of from it's position. This has only been happening since I've updated to 5.6. It was working fine in 5.5. Would anyone be able to help me on this?

[dire trench]

I have absolutely no idea what happened in the above video either, I can confirm it did only happen by updating from ue5.5 to ue5.6 😅🙃 Set Skeletal Mesh seems to have a jump/spawns a bit above their actual lock points when set oddly. The skeletal mesh component is already attached to the character.

No code or bp changes besides the update.

[jagged moss]

Can anyone see what im doing wrong? the one with 8 works, the one with 4 does not. I have rebuilt this from scratch and even copied it but I cant get the one with 4 to work and i dont see what im doing wrong. Its suppose to find the highest forward vector and save it

[maiden wadi]

Seems fine, assuming your 1234 properties are set correctly.

[jagged moss]

they are arrow components, issue is that it returns the wrong one on the one with 4. i cant figure out why. im not sure if it returns randomly or if its a pattern to it

ive been stuck on this for hours and i just cant figure it out, tried rebuilding it so many times, maybe there is something else causing the issue but im not sure what it could be

[maiden wadi]

For a start you could debug draw your values near their arrows.

[jagged moss]

thanks, i didnt fully know how to see it but set up another debug tool for it now with an event tick and it seems the numbers are inverted so swapping the greater with a lesser node and it works

[maiden wadi]

Not entirely sure what you mean here since a character is already kinematic. At least their capsule movement. But if you want it to be similar to the spectator, put it in flying mode.

[jagged moss]

any thought on why forward vector is negative on one and positive on the other even tho both using the same arrow components?

[edgy marsh]

I want to make car pawn into clients but car pawn's inputs are not working on the client working in only standalone how do i fix it?

[maiden wadi]

Off the top of my head, none. The forward vector is the component's facing direction. There's no chance you accidentally set them facing the wrong way? I'm vaguely sure that even like.. inverting the scale of the actor wouldn't casue that to be incorrect.

For walking mode, no. You need gravity to walk, kind of a prerequisite. Flying mode will act identical to the spectator pawn though if that is what you're after.

[faint pasture]

Show your current code, from the player's input all the way to the text being updated

[maiden wadi]

For a start, basically never use GetPlayerController in networking stuff. You always have contextual ways to get the correct controller related to what you're doing.

For example, look at your Event Possessed node, it has a Controller.

That node won't do what you want it to do though. If you look at it's tooltip it states it only runs on the server. "Event called when the Pawn is possessed by a Controller. Only called on the server (or in standalone) "

Override ReceiveControllerChanged instead, that has a NewController. You can use that to pass to your subsystem getter node.

[vestal dragon]

Ok I’ll so that in a lil while

[maiden wadi]

There should be a set movement mode function I think. I can't recall off hand. But you should be able to set it either by default or on beginplay.

[faint pasture]

Not sure if that's hte best way to do it but it does the job

[maiden wadi]

It'll work. Realistically you shouldn't need to apply these at runtime. Walking, Flying, Driving, Boat inputs are all separate and should be so that you can set them separately in the options menu. You can just apply all of the contexts at the start of the game and rely on possession to change the controls.

[jagged moss]

i mean its an arrow and its pointing in the right direction, so i dont think so

[maiden wadi]

Yeah I dunno. :/ I was thinking the same thing when I wrote that, that it'd be hard to make the arrow face the wrong way.

[edgy marsh]

still not working

[edgy marsh]

I want to possess the car pawn but Inputs started not working its only working in standalone

[faint pasture]

show the code path from some input to the car being possessed

[faint pasture]

all the way back to the input

start at the input node and show the whole path

this multiplayer?

[edgy marsh]

yes

[faint pasture]

so where's the bit where the client tells the server that it wants to do a possession?

between your input and the possess call you need a run on server event somewhere

[faint pasture]

not multicast, a run on server event

[edgy marsh]

ok

[faint pasture]

the client has to tell the server it wants to possess something

and you don't need to pass over the controller, just use the pawns controller on the serverside, not get player controller 0

[edgy marsh]

get controller?

instead of player 0

[faint pasture]

sure

because player 0 on the server might not be you

[edgy marsh]

still not working though

like this

[faint pasture]

The server knows about the controller

just pass a ref to the pawn you want to possess over

and it should be called ServerPossessCar, you are telling the server you want to possess the car

[nova imp]

I have a question that mixes a bit of Blueprints & Materials I posted it in both channels (hope that's ok)
I'm trying to make a material that can give me an outline that adjusts to the "tiles" as a group outlining the whole shape when multiple pieces are put together. (the red lines are the actual planes & the blue lines are the material effect). The screenshot is a prototype of the system I got to work but it requires having around 16 material instances with 3 or 4 layers on each and a lot of selects or branches. I just don't want to believe that this is the only way to do this. (not an expert on materials so maybe I'm missing something). I've thought about using a more modular approach with just one material and way to many lerp nodes but I worry that it'll be too heavy as to my knowledge unlike static switches lerps still have to "load" the nodes that won't be visible. Any help is appreciated thanks in advance 😅

[rose citrus]

Can I only set variables from the AnimBP on Update Animation? On the Enemy BP, I get the Anim Instance, cast and set a reference to the AnimBP, then on Death Event, I get AnimBP ref and set isDead. The variable doesn't change in the AnimBP.

Usually I just use the Enemy/player References from their AnimBP to set variables, but was trying to see if I can set it from the enemy/player BP instead so it's not setting the variables every tick

[maiden wadi]

To start, lerps are fine depending on where you use them. Using a lerp at the start of two very huge diversions of shaders with several hundreds of instructions on both sides is not so great.

And to be clear, there's no loading here. It's on the GPU, everything is loaded, it's simply processing those shaders each frame.

But to get the blue outline, I'd probably default to something like the post process outline stuff. Create a mask out of your meshes by marking them with a custom depth stencil value that you can read in the post process.

[nova imp]

Okay so the one big material isn’t happenning then.
Makes sense, so the processing would just be a lot longer if I use an unoptimized material.
I’ll give the custom stencil depth a go didnt think of it and will be a lot easier than what I was trying.
Thanks for the help

[kind willow]

I'm trying to create a point&click game and use 2 widget buttons to rotate the camera. When button is hovered over, camera rotates, but the issue is that the buttons also consume mouse clicks, meaning that objects in the rotation zones cannot be clicked (See 2nd image, where the trace hits just stop on the sides)
Is there any way to make the buttons pass the clicks trough?

I guess I could use images instead of buttons, but then the logic of "is hovered" would have to run per tick

[lofty rapids]

just check the x, if it's > or < then

this way you don't even need the widget

[kind willow]

I tried that, but I had issue with the user's screen resolution, which would mess up the alignment of the rotation zones

[lofty rapids]

ya usually you get the screen into a -1 to 1 or 0 to 1 range

[kind willow]

For some reason get cursor position and get viewport resolution would give me 2 different values

[lofty rapids]

i have not done that yet in unreal tbh

[kind willow]

me neither. This is my first point and click game, hence my struggle with the basics

[lofty rapids]

did you try this node ?

[kind willow]

Yup, used exactly this one

[lofty rapids]

and you tried the other ones

the viewport one, and the other one ?

[kind willow]

I also used this, but as I said, the value shown by get mouse position and get viewport size are calculated completly differently and seemingly not compatible

I cannot determinate the centre of the screen

[faint pasture]

what does get mouse position return when it's in the corners?

[kind willow]

Left upper corner returns 0 0

[lofty rapids]

center of the screen should 0.5,0.5

[kind willow]

0,5 would be like half a pixel from the left

Usually I'd divide the mouse locatrion by screen width to get a dot product, but the screen resolution and mouse position numbers are completly different

[idle crescent]

Has anyone tested at what instance count removing instances stalls?

[lofty rapids]

i got in 0 to 1 range, which is what you want

this way always 0.5 is center

[kind willow]

No idea then. Maybe it's some difference in engine versions? I'm on 5.5.4 and I only get distance from left from the "Get Mouse Position Scaled by DPI" node...

[lofty rapids]

this gives you 0 to 1

[kind willow]

Oh, I see. Let me try

[lofty rapids]

left to right

no matter the size of the viewport

so 0.5 is always center

i use zero to one a lot in unreal lol

but there is also -1 to 1

so zero is center

[kind willow]

Huh, not sure what I did wrong before, but yeah, this works. Maybe I multiplied the wrong thing?
If I can't figure out the button thing, I'll use that instead. Thanks 👍

[lofty rapids]

just say if you greater then 0.8 your on the right, or less then 0.2 your on the left

or whatever numbers make sense

this is easy just flip some booleans

[kind willow]

Yeah, I can take it from here, I just didn't know how to get the value right I guess

[atomic solstice]

Is this bad practice?
I have a simple button BP that triggers stuff when I click on it, but I also wanted to press G to trigger it.
Aren't I supposed to put Keyboard event stuff like this into the PlayerCharacter BP's or is it ok to put inside the button BP?

[maiden wadi]

Really requires context of the game type. What is clicking on it? Are we an FPS/TPS game pointing the camera at it? side scroller with character standing on it? etc.

[atomic solstice]

Initial button press requires me to look at the button but I don't want the G key to have to "click" on anything.
I just got tired of constantly running over to the button to trigger it during runtime. I guess its just for testing purposes? Was curious if I'm comitting some cardinal sin for BP's 😅

@maiden wadi

[maiden wadi]

If it's just for testing, it's kind of whatever. 🤷‍♂️ But for future reference, it may be easier to trigger it from console. Makes it easier than setting up inputs on things.

If you have an object with say a custom event named MySuperCoolCustomEvent, you can trigger that on all instances by doing "ke * MySuperCoolCustomEvent", ke standing for Kismet Event, the * is for all instances. You can put the exact name in there too if you only want one instance and you know it's object name.

[icy gust]

Anyone know why pressing E isnt working here? It works fine with the same function in a seperate blueprint but it doesn't fire at all in this one. Both have the same input and modifier settings

this is the exact same setup in a separate blue print that works fine

the overlapping works, its just the E press does nothing

[sick sky]

where is the working and not working BP event node placed ?

[icy gust]

Nvm I fixed it and it was super simple, I just had to enable the input for this one for some reason

I'm not sure why the other one works without that though

[dusty cave]

So I've been doing some testing lately, and found a way to get similar results to multicast, but without replication nor calling server events.
I do this by binding Event dispatchers from Data Assets onto regular events triggered by the player.
Apparently, data assets work similar to the gamemode, by letting the player get server-level clearance.
Is this useful, or should I stop this tanget of research?

[rustic sundial]

is there a node for assigning a tag to an actor or component?

I want to be able to spawn a mesh into the world during runtime and give that mesh a random tag with each spawn. How can I achieve this??

[next hollow]

Get the tags array, and add to it.

[onyx tapir]

☝️

[rustic sundial]

what is "the tags array"?

Are you talking about the gameplay tags or are you saying I need to make my own tags array

[onyx tapir]

It's an array of names that all static meshes come w/ same as actors, no need to create your own.

[atomic hollow]

you will need to enable the input for the actor to get it.
it is in class defaults, search receive input or something same.

[fleet prism]

Is anyone able to let me know why this is not working properly? The goal is to have the door open when you put the box in the hole and when you take it out the door will close. and this works my problem is when the cube is sitting in the hole instead of the door staying open it will constantly open and close. So how do I make it so it stays open when the cube is in the hole?

[atomic hollow]

the two events for overlapping can be triggered multiple times very fast and is not suitable for this situation
Find distance between the overlapbox position and the box position that need to be placed in the hole and check on tick every 3 to 5 times per second depends on your situation. And see if the distance between them is nearly some threshold the door will be opened else the door will be closed.

[foggy otter]

any idea why this instantly crashes the editor every time? for context, im doing listen server multiplayer. this gets run on all computes. tho running with only 1 player crashes too. are these guards somehow not enough? the material itself is fine, manually adding it to the camera works no problem. im on 5.5.4

[zenith egret]

Hi, I am experimenting with the new gameplay camera system. I am facing an issue with the Rotation Offset. Whenever I set the x, for example, to 1, the value keeps on accumulating leading to wrong behavior and the camera ends up in a weird pose.

I tried different offset spaces but they all behave in a wrong way ..

appreciate the help, thank you

[dusky cobalt]

is cube and box 2 different items but they are both have the same parent PickUpBase?
or the problem is that when you start game with cube/box inside the hole it's acting like that?

is the hole a box?

[maiden wadi]

I'm unsure how your test was set up, but this won't work normally. I'm assuming that you're testing in PIE? If so, I assume that you're getting a broadcast off of the static asset. Your data asset is application global. It's similar to a static mesh asset, you don't want to load it twice just to display it in two different PIE instances. Similarly with data assets that are meant to house unchanging static data, there's no reason to load them twice so you get the same asset in both pie instances.

I'm assuming that you bound a dispatcher to this on both pie players somehow and made one broadcast, which ran events for both pie instances for this reason. As a point of test for this, you can see the callbacks even if you're in a non networked pie test in two separate standalone instances.

In a real situation there is one single class that can determine networking and that is Actors. You have to have an actor channel to communicate with the same actor channel on another machine. ActorComponents and other similar subobjects all use their owning actor's channel to do their networking. Data assets have no owning actor and no context to do networking.

[maiden wadi]

Can't help much with that without a callstack or at least crash reason.

[frosty heron]

Surely this is misunderstanding on your end?

How does binding event dispatcher to a data asset have anything to do with server telling clients to run function.

[dark drum]

From my understanding data assets don't replicate. (As they're intended to be immutable data) If you're testing locally in the editor, all pie instances would use the same data asset. This wouldn't work on a build as all clients would then have their own instance of the data asset, which aren't linked or replicated.

[frosty heron]

They dont but what he is doing has nothing to do with replication or rpc

He just bind the event on all machine and they get called when it get called.

This is the same as like having an overlap event in an actor and thinking theres some sort of multicast or rpc happening.

[visual crest]

I need some help with gimbal lock. I am rotating accessories via UI. Any time Y is around -90 or 90 X and Z do the exact same thing as each other

[maiden wadi]

Manually recreate the rotator.

Like... You're at 0 yaw, 0 roll and 89 pitch. If you add 2 to pitch, recreate this by flipping yaw and roll. Move them to 180 and 180 and then set pitch to -1.

[visual crest]

Ok how do I do that in nodes?

[kind willow]

How do I get the skeleton object reference from an animation asset?

[maiden wadi]

Editor isn't open so can't do it. But the simplest way would be a function library. Make a function that takes in a Start and Delta rotator. Normalize them. Createa new local variable called EndRotation. Add each axis of both rotators together and set them in this EndRotation. Then do branch checks to see if the pitch is > 90 or <-90. If so invert EndRotation's Yaw and Roll by adding 180 to it. Normalize them again and return.

[visual crest]

Ok Ill try. Thank you. My start would be from get transform rotation? and my delta would be my current + the slider value?

or delat be get transform rotation + slider value? If its current were would I update my current rotation Variable?

[maiden wadi]

Start is the current rotation of the object. Delta is how much you want to rotate it by, so the slider value

[visual crest]

thanks

[cedar remnant]

Good morning! I have a general BP question centered around how the engine executes BP nodes.

In the pictured example, Do rows 1, 2, 3, and 4 execute on different frames? Or do they all execute on the same frame?

[maiden wadi]

Same frame. You have no latent nodes here.

So this is all execution blocking. Has to happen in order.

[cedar remnant]

So even if I’m calling different events it doesn’t disrupt the logic from executing on the same frame?

[maiden wadi]

I'm not sure how best to explain this. Are you more familiar with any written languages?

[cedar remnant]

As long as the node isn’t Async I’m good?

I’ve written a good amount of C++ in Unreal though some of the technical terms of scripting language might be foreign

Calling events is just like calling different functions in C++ no?

[tight pollen]

I have fps drops, I don't know why, I didn't have this before, I don't know if the editor started to malfunction or what

wait for task

[maiden wadi]

If you're familiar with C++, then what you just pasted is relatively similar to...

void ActivateAbility()
{
  if (CheckAndSetupCachables())
  {
    ActivateWeapon();
  }
}

void ActivateWeapon()
{
  HandleShotFired();
}

void HandleShotFired()
{
  EndAbility();
}

I put your macro in an if statement because I wasn't sure of it's internals, but it looks like a stopper, so similar to a check.

But your code in BP there would run the same as if you wrote it like this in C++.

the exception migh tbe that macro. I'm not sure what you're doing inside of it.

[maiden wadi]

This at least looks like editor stuff. If you're profiling game stuff I would advise doing it in Standalone at least. Cooked is better. In editor you get a lot of false data you have to sift through like slate time being really high. If you're profiling the editor on purpose, hard to say with just slow paint path. Need more data in the profile to know what widget is causing that paint function.

[cedar remnant]

Nothing but a couple casts. Nothing Async/latent. thank you!

[floral stump]

🤔

this blueprint was compiled originally in 4.26 and it gives this error in 5.4

but if I recall a fresh Set Text from the return value it fixes the issue

[surreal peak]

They might have changed the original one to not be exposed and exposed a new BP version with a display name.

[thorny kestrel]

Is it possible to connect input value from different event/exec results?

In the picture, the above and below logic are the same (begin/end overlap)

But I cant connect the other actor to the above logic, I have to copy and paste the whole thing down.

Any methods in solving this?

[full badge]

promote input as a variable and set it after event

then just use the variable

[thorny kestrel]

I thought about this, but won't that make my local variables messy?
Since I might encounter the same situation multiple times, making multiple temp variables seems weird.

[full badge]

im also annoyed by this
another solution is to create an event and pass the variables as input
then just call the event

[thorny kestrel]

I think there's some hidden methods to enable it
Deactivate node built-in can take multiple inputs like so
I'll take the advise tho, thanks.

[full badge]

that node is calling a function of an object

as long as it has no return value it can take multiple input

you can do the same thing with your own actors/components

you can also directly pass an array of that object

[tight pollen]

in BP

In Anim BP

how can i fix it?

[jagged moss]

Why isnt there just a checkbox if pressing enter is gonna commit or not? do i really need tons of functions to make it work?

[maiden wadi]

Need more context. What is your issue here?

[jagged moss]

when using a text with multiple lines in a widget it consumes the Enter key and makes a new line when trying to press enter to send.
I swapped it with a normal edit box and it works now, but i could not get it to work with the Multi-line Editable text

[sick sky]

right click on node and see options to add entries

[crude hearth]

OMG Thanks

[spark steppe]

or use a chooser table

[tranquil path]

Hey, I have a question. I’m working on a Hearthstone-like game, but in 3D, with cards as 3D models. Right now, I just want to animate them with some simple translation, scaling, and rotation.
However, in my project, a single card is made up of multiple skeletal meshes assembled to look like a real card (for now, they all only have a root bone).
I’d like to know how to create these animations and how to play a single montage that would apply to all skeletal meshes at once for example, if I want to shake the entire assembly and store that in one montage.

[tacit kayak]

You can create a new skeleton with exact same bones animate it, and then make all card part child's of that skeleton and then, I don't remember which one is but then you need to put a node that syncs all the animations by following the skeleton animation and applying them at the same time

[tranquil path]

Thanks! I didn’t know about that method at all, but it’s exactly what I need. I found the node you were talking about it’s either SetMasterPoseComponent or Copy Pose From Mesh. Now i just have to play the animation on the master skeletal and it will spread over all childs, I'll try this

[tacit kayak]

It wasn't that node but if work, you know

[unkempt plover]

Hi I have a question, I have a really big world, and in that world I have some animals. It looks something like this from above. I have created some places where some random animals exist for example this one...

But on runtime I want the player to be able to take one of these animals, like think for example of a horse. Take this horse by the lease and move it somewhere else in the map. So I want to move that nav mesh box somewhere else in runtime. aka recreate it, this will be the box which the horse will move around in... So the animal NPC will not be able to move too much, but only move within a short box or sphere radius.

I tried to look this up on youtube, but I was able to find something like this.. https://www.youtube.com/watch?v=YAStYjqSVzA&t=307s&ab_channel=GamingDev2020

Dynamic Navmesh and navigation invokers. I also tried reading a bit into the documentation of "Modifying the Navigation Mesh" at dev.epicgames.com but It didn't have anything related to moving nav-mesh in via blueprint in runtime

[maiden wadi]

I'm not sure I'd rely on Nav areas for this so much. Usually it's best to do these kind of restraints in your actual AI code. Your navigation mesh stuff should be kept stupid simple because it's fragile enough as is. It costs a ton of frametime to update sometimes and the more you can avoid that the better off you are.

[unkempt plover]

sure but I have a big map, 8k x 8k and if I had to do these restraints in my AI code then I'd still need to have the Nav Mesh cover the entire 8k x 8k landscape right? That also has a high resource overhead, thats why I thought of keeping the nav meshes shrunk into small chunks

[maiden wadi]

Yeah, not sure there. I know some open world stuff uses nav invokers on the aI themselves. How they manage complex pathing I'm not entirely sure because I fought that in some of our bigger maps in an RTS. Wanted to get rid of the huge navmesh volume around the level but couldn't really come up with a way to use invokers well.

Realistically I don't think that the navmesh around the level would be an issue for us with a static level. But our maps are 100% generated. So it's a chunk of time at load after the map is generated that we can't just cook with the map. 🤷‍♂️

[unkempt plover]

https://youtu.be/9LiqhyYdpks

I found something better

but this is for AI pathfinding to the player. I tried to do the same thing only this time instead of giving the player this component. I gave it to my NPC. But still doesn't work as intended. It didn't change the nav mesh.

I used the command: ShowFlag.Navigation = 1 to debug it

I also changed the following settings in project settings

I guess this isn't really made for passive NPCs but for hunter ones that chase you

[odd compass]

Hello, does anyone know a way to fix the Project World Location To Widget Position node, my issue is that when an actor is barely off screen the node will project the widget in a 3d Space rather than a 2D space, and when the player is facing far enough away (for instance, facing the complete opposite way of the actor) the node will fail and project the UI at (0,0) in a 2D space. I have some pictures of in-game and of my blueprints

[visual crest]

Do you have the editor open now? My gimbal lock salution didn't go so well

[thin acorn]

If I teleport my character high into the sky and let them fall, they clip into the Landscape at the ground and keep falling while being stuck in the ground.
The character is the basic FirstPerson one provided by UE5

I think the issue is with how I'm teleporting the player

This works, no idea what the differences are

[visual crest]

I need some help with gimbal lock. I am rotating accessories via UI. Any time Y is around -90 or 90 X and Z do the exact same thing as each other. Authear tould me what to do but I flubed it up some where and I am not sure how to fix it.

Any help would be awsome. This whole gimbal lock problem thing I just can't wrap my mind around it at all... I just don't get why X is not all ways X and why and Z can become X.

[maiden wadi]

You may also have to manually normalize pitch. I think the normalize axis only works at 180. Can you show what it's doing atm?

[visual crest]

Its doing about exactly what it was doing before any time Y is near 90 z and x are mirrored.

What do you mean manualy normalize pitch?

[maiden wadi]

Basically if you have a pitch that is 93 make it 87. If it's -93 make it -87. If it's 120 make it 60. Etc.

Actually that might not help either. 🤔

[visual crest]

If I did that then items will not be able to be in certain positions and 90* angles usaly look the best

[maiden wadi]

I'm not sure you can solve it entirely without saving pitch as it's own thing fully outside of the component's current rotation.

[versed sun]

I took an easy route and clamped it -89.9 to 89.9

[maiden wadi]

Cause the issue is, you set pitch over 90 from like 10 degrees over 85 to 95. You normalize that to 85 and flip roll and yaw. But now what happens when you need to up pitch again. You get gimbal lock by going up again.

Some weather systems save the rotation as a whole 0-360 value and just set it directly.

[versed sun]

can you change your < and > to 89.9

[visual crest]

I can but what good is that?

I changed it it did nothing....

[maiden wadi]

@visual crest

This is a showcase for using the current rotation to add vs saving a persistent rotator and adding to that and using it to set current.

[visual crest]

so just get current and add?

[maiden wadi]

No, that'll get stuck. That's what red is doing.

Blue is just a rotator variable that gets it's pitch added to. Sec. I can show this a little better.

Look at the blue numbers for P. Bottom is the rotator, top blue is the current rotation of the arrow. Note that the rotator's P just keeps getting added to.

[visual crest]

I see

So sliders might not be the best thing here then?

[maiden wadi]

Sliders are fine. In fact if you're using sliders you could set their values directly from the slider and it'd avoid issues.

[visual crest]

I have been using slider and still having gimbal lock problems

[maiden wadi]

Your pitch slider is set between -90 to 90?

I assume you're talking about a literal USlider in a widget.

[visual crest]

Yes and I have -180 min 180 max I have also tried 0 min and 360 max

[maiden wadi]

Test this. Set the component's RelativeRotation directly from the slider values. Yaw and Roll should be -180 to 180 and pitch from -90 to 90

[visual crest]

It kinda works but you really have to fidle with it to get the rotation you want and X and Z are still constantly getting mirrored

I checked with AI and Chat gpt says i should use Quaternions instead of Euler like I currently am but I have no clue how to do that and its instructions are extremely confusing.

[maiden wadi]

You can't do that in BP. And it doesn't so much apply here. Realistically you won't get much better than setting the relative rotation from your slider values. Quats are for things like flight rotations or spacewalk rotations kind of thing.

I'm not fully sure what your issue is with the mirroring and such.

Maybe if you were using a gimbal wheel thing. Like the rotation tool in engine, quats might help. 🤷‍♂️ But for sliders for each angle, not so much.

[heady burrow]

question, is there a way to have a second tick node? I want to encapsulate the workflow of my RTS piece creation block

so for example, if I want to move the soon to be ghosted piece actor, I have to put that in the tick execution line

no idea how to do it differently

ideas welcome

[maiden wadi]

A Second node, no. You need to either make two functions called in order, or do sequence nodes.

[heady burrow]

bleh

[mental rampart]

when you "blend" between two cameras, does that mean the view itself blends from one location to another?

or is it "blend" in the video editing sense

[lunar sleet]

It just means it’s a smooth transition

[mental rampart]

a smooth transition between locations or like a windows movie maker blend

[lunar sleet]

It will move a ghost camera between camera a and camera b yes

[mental rampart]

ah ok

thankyou

So i have a camera facing down on a car, but when the car flips over, the camera flips over too and goes through the floor (because of the way its rotated) how would I make it so the camera is always in the top-down position no matter what the car is doing?

bit of a loaded question but hopefully someone has an answer

[maiden wadi]

Is the camera always supposed to be facing down?

Like typical top down camera following what you're controlling?

[mental rampart]

it's a generic chase camera for a car. i guess by "top down" i mean it's angled downwards like any car game has

my bad, probably should use better wording

[lunar sleet]

You could maybe just rotate the car’s mesh instead of the whole actor and make sure the spring arm is parented to the actor itself independent of the mesh

But if that doesn’t work maybe have the camera a separate actor and change its location on tick to match the car’s location (offset for your camera angle) but not its rotation

[dusky cobalt]

Did you put the camera into same blueprint as car like it’s your main character that you follow ?

[mental rampart]

yep. it's the same bp as the car.

[dusky cobalt]

yeah so it follows something it's attached to, like it's relative location will be to whatever it is attached to, if you want to have camera that is separate from anything and is like in top-down games then create pawn that you posses and put camera on it, you can make a toogle that you click space and it will follow the car or unlock from it as well if you want

[lofty rapids]

seperate camera actor for sure

[surreal peak]

Or use the PlayerCameraManager to just return the camera location and rotation you want.

Good morning, I'm creating a dual wield mod for the game Oblivion Remastered and I'm having some issues with I believe the blueprint logic or animation blueprint?When I get ingame and press my desired key to switch to my animation BP nothing happens. Still only unsheathes 1 blade so not showing my dual swords either. I know I haven't setup hitboxes and have only got the logic for the right and left attack put down for now, I want to make sure I can get the swords showing ingame and that I can get even 1 animation to play before creating the rest. I also am assuming that I have the parent classes for my animation blueprint or my logic blueprint incorrect. I'm baby brand new to this stuff so I'm honestly not too too sure what I'm doing lol

[lofty rapids]

so basically your trying to switch the animation blueprint to your new one right ?

and it's when you press k

[trim matrix]

Correct

[lofty rapids]

any errors ?

[trim matrix]

Not that I can immediately tell, the game doesn't crash and Im able to successfully do the console command to add the mod to the game and load it it's just doing nothing when I press k

[lofty rapids]

can you print messages in the game ?

put a breakpoint on the set anim instance

does it hit when you press K ?

idk about modding, but normally you can print string when you press K

this way you can see if the key is registering

which it should be, but with debugging you should confirm things not assume

[trim matrix]

I see, Ill setup the print string and see what happens. I appreciate your responses and help!

[storm vigil]

Do we need to async load (soft objects) animations sequence or montage in the weapon blueprint for weapon animations? or its footprints are too low to add another logic
Btw, im using semi procedural, so its mostly the idle and reload animations leftr

[maiden wadi]

That's up to your game size and how big the files are. Generally speaking though, it's usually best just to load gameplay critical stuff as bundles which is why primary data assets exist.

[mental rampart]

How do I possess an external camera that is seperate from the controlled pawn?

is it this?

[maiden wadi]

You don't possess it. But if the camera is on a separate actor from the pawn, you can SetViewTargetWithBlend on it.

[analog heron]

Hey I am getting this weird issue with opening a level in UE5. I've have a collision end level that simply opens a level by object ref if it's player. But for some reason it keeps trying to open that last level then the new one and flips back and forth. I've been stuck for ages on this and it makes no sense what is happening. Here's a video of the issue happening. I have tried the same method on a different project and it worked just fine. It's most likely a simply fix and I'm being a moron but I can't see why this is happening. Cheers for any help with this.

nevermind I was just being stupid

[dusky cobalt]

don't say that, things like that happen everyday couple of times in game dev 😄

[civic oar]

I couldn't get this event feed on the bottom left of the screen to work entirely properly--it does update the first slot though, but the bottom three slots never update correctly. I created what is called a "structure," which I think is the equivalent of a container, which contains the text box itself and the text. So I iterate through the structures in the "Event Slots" array, update the text in that text box and store the previous value in the "Text To Move Down" variable. That's as far as it works, something happens after that which fills the other three event slots with empty text.

Here's where I construct everything:

[maiden wadi]

You're modifying copies here for a start.

Check your Get node. It has a circular dark blue pin. Change that out for a Get(by ref) instead of Get(copy). It'll have a dark blue diamond pin.

[trim matrix]

I seem to still be having an issue with input being registered. Tried doing print string and copy to clipboard as a test but nothing happens upon key press

[dusky cobalt]

These Input Actions should be in your PlayerController, try adding any key to PlayerController, and print you will see it starts to work, so then you will have to modify architecture so PlayerController handles inputs and sends the logic to happen in things that are supposed to do something.

Also preferably you should get to know Enhanced Input Mappings and use Input Context Mapping with Input Actions.

[trim matrix]

I was just looking into the enhanced input mappings in project settings I'll definitely give this a shot thank you very much!

[dusky cobalt]

Yeah, and mosty likely current issue is just that Input Mappings are not possible to be used from Character, their place is in PlayerController

and btw these that you are using are valid for debuging and just doing things quick

[maiden wadi]

You can use input mappings from a character?

[civic oar]

I’ll be back on my editor in several hours, I’ll update you then.

[dusky cobalt]

oh, then maybe @trim matrix you are spawning wrong class of your Character?

that is why these dont work

[trim matrix]

I just changed the parent class to player controller

[maiden wadi]

Input needs three things if you're using enhanced input.

[trim matrix]

Which makes sense controlling the player since im trying to do dual wield animations

[dusky cobalt]

PlayerController is PlayerController, Character is Character, don't mix them 🙂

[maiden wadi]

Your input mode needs to be set to Game or GameAndUI.

The pawn with the input needs to be possessed, our the input needs to be in your player controller, the level, or some other actor you have explicitly called EnableInput on.

You need to have the correct input mapping context applied with your input actions.

Past that, you can put input actions in any class mentioned in the second thing above and they'll work.

The input mode functions as a full "you can or cannot have game level inputs", the input context mappings function as a filter, and possession is just a special case for enabling input in the actor.

Does Oblivion Remastered use Enhanced Input or are they still using legacy controls?

There are some debug key inputs you can use that'll ignore the context mapping filters as long as the actor has input enabled to make sure that's not an issue.

[trim matrix]

Ohhhh I see I see, I know it was made in ue 5.3.2 so maybe enhanced? I wouldnt wanna assume im not too sure

I did try and change the setting to possess but that resulted in a crash Im hoping since I now have the correct parent class set I should see results or I hope so

[maiden wadi]

Likely enhanced input then unless they went to a lot of trouble to backport it. Which wouldn't make much sense.

[quaint vortex]

Hey. I have a question - i would like to set Expose on Spawn to Struct, but i don't have that option. Is it removed or i made something wrong?

[maiden wadi]

Making it a player controller won't help. You already have a player controller and it's a singular class per player. What are you making specifically? Is this like your played character or is this like a display dummy thing?

Or some NPC, etc.

[maiden wadi]

What class is this in? And this is a normal BP struct?

[trim matrix]

My knowledge is so brand new but I am trying to upon key press switch animation blueprints for the player character to my own so when I equip my dual swords it will play my own dual wield animations

[quaint vortex]

Yes. That's normal structure

[maiden wadi]

What class is your screenshot from? What is it's parent class?

[quaint vortex]

That's a widget. I would like to connect to structure.

[maiden wadi]

Do you happen to know if they made that on top of Lyra or did something similar? Lyra has a nice way to enable features dynamically. Essentially your mod could inject an actor component into the player's character or controller that you could put your input and logic in. Or is there any API for anything like that?

[maiden wadi]

Which widget class specifically? I tested UserWidget and Widget and I can't seem to cause that. 🙁

[trim matrix]

I apologize but I have no idea. I've mainly been mesh modding this game since it came out and now after learning how to get cloth physics working I was wanting to do something more technical involving blueprint modding and dual wielding is my most wanted feature/mod

[quaint vortex]

UserWidget

[quaint vortex]

I can set that for Integer, Bool etc, but not for structure

[maiden wadi]

Huh.. Neat. The gate for that is quite small.

Can you test creating a new BP struct and check if that shows?

What is in your item struct?

It's also worth the question of whether saving everything and restarting the editor fixes it?

[quaint vortex]

It works on new structure

[quaint vortex]

But replacing references crash ue xD

[maiden wadi]

I'm trying to recreate the issue. But from looking through code, I can't see a reason for that. It's worth a note that a lot of people start C++ for this reason. Blueprint structs are notoriously cursed for multiple reasons.

Yeah I can't cause it even purposely doing a circular dependency. 🤷‍♂️

[quaint vortex]

I recreated references by hand and works. Good that it's beginning of project and was only few to fix.

[trim matrix]

How do I add a player controller to a key press?

[dusky cobalt]

You need to create new class with a PlayerController as parent. Then in your level you settings (GameMode) you set that PlayerController as the one you want to be working. When you enter the level it will then use that PlayerController class. Inside it you can just add these Input Actions (keys) -> and then execute do x and do y.

These should also actually work from your Character.

Btw if you show what you have so far or what you are looking at it would be easier to probably help you. Also did you try to print anything and did it work or not?

[trim matrix]

This is my logic setup right now, and yeah my inputs aren't being recognized or doing anything when pressing them

My combat idle animation is playing when I get ingame but thats about it

[dusky cobalt]

add these nodes to your character

these are related to player controller so you will ahve to use GetPlayerController node first instead of self in my case

and same for ShowMouseCursor (it's also in PlayerController)

[trim matrix]

Do I still set my anim instance after the red set node

[dusky cobalt]

Let's figure out first if your inputs are working

[trim matrix]

How did you set the show mouse cursor node without the blue target node

It wont let me compile without a target

I also don't know how you got self to connect to player controller

[dusky cobalt]

you need to use GetPlayerController because you are not doing it in PlayerController

[dusky cobalt]

^

[trim matrix]

I see, and this will allow input to be recognized?

Sorry Im so new to this the ins and outs and all the logic gets overwhelming very quickly

[dusky cobalt]

Take it slow and try to understand small things first and basics. Yes, this is one part of making input beeing recognized. It's all about trying and trying. If it doesn't work still don't worry there might be something more that needs to be done.

Did you watch any like really basic tutorials to get a bit more info about UE or did you jump straight into it 😄

[trim matrix]

I always dive right into the wolves lol

I figured most of it wouldnt apply since im modding a game and not making my own

So I'd need to adhere to any kind of stuff Oblivion Remastered has already done or so I assume. I dont know anything lol

[dusky cobalt]

oh it's not gonna be easy to skip a lot of things without literally giving you step by step solution which you won't learn much from it

it's ok to ask questions, but I would start with check pinned messages, there is a blueprint introduction tutorial

then you can watch tutorial about Enhanced Input Mappings

this will already give you a lot

[trim matrix]

I appreciate it, I dont want to sit through a 2 hour video for input mappings but im sure i'll figure it out eventually

Thank you guys very much for helping me out and responding today!

[dusky cobalt]

if you have questions just go ahead and ask them, best if you have any context, screenshots, errors etc. it's easier than guessing

[trim matrix]

I just know I have the animation blueprint and my state machine with it's transition rules created, I have the blueprint for the logic down which is the screenshots above, and the inputs ingame aren't being recognized. I tried changing the parent class for my logic blueprint to Actor, Character, and PlayerController but they all still havent led to inputs being recognized

[dusky cobalt]

is this Character spawned in the level?

this CosmicDual..

[trim matrix]

Ingame? Yeah I spawned the blueprintlogic

At least I think I have the right one spawned lol

[dusky cobalt]

can you check what did you put into level?

[trim matrix]

When I load p in game the combat idle animation from my stuff is playing and yes I will

Okay so I have no idea what I did differently but I made a test to copy to clipboard that K is pressed when I press K and it recognized that input!

[dusky cobalt]

and can you show how did you added this?

[trim matrix]

But now my dude is in a tpose lol

And the actorr I spawned in is my dualwieldlogic blueprint

[dusky cobalt]

oh, instead of copy to clipoart search for Print node

and test, it's much easier to see

you can write there something and it will show in the left corner, so it's perfect for debuging things

also if it works the T pose is because of logic on Event Tick

put print on event tick so you can see what it does

[trim matrix]

Do devleopmental only nodes like that work in game? Or is that in level editor

I figured I couldnt test stuff in the level since it doesnt operate like oblivion re ingame does or I assume so

[dusky cobalt]

what do you mean? how are you testing it? are you packing the game?

[maiden wadi]

Development Only nodes work in editor and cooked builds that are not Shipping.

[trim matrix]

Yeah I package and test ingame every time

[maiden wadi]

You don't have a way to test mods in PIE? O.o

[trim matrix]

Im not sure what pie is but I just assumed the level wasn't the same environment as being ingame in Oblivion so things would behave differently

[maiden wadi]

PIE is the Play In Editor. Little quick test tool.

And 85% of things function same. There are caveats, but for input handling, spawning, messing with animations and such, it'll be 1:1

[trim matrix]

Oh shoot yeah that will eliminate the hassle of going back and forth

Thank you

[dusky cobalt]

Don't assume, just try

[trim matrix]

I do be asusming things

[dusky cobalt]

also if you packaged with Shipping then you don't see Debug tools

all other modes allow you to see prints/debug tools

[trim matrix]

I am in development and Ill look up how to place my dude in the level and control him

Let me stop asusming and try

[maiden wadi]

I had to test our last project a lot in Standalone/Cooked. 🤮 Ugh, never again.

[dusky cobalt]

sounds like pain 😄

what was the reason why btw?

[maiden wadi]

Just some bad structure we never changed. Moving from lobby to combat game is seamless travel. And you can't test that in PIE.

[dusky cobalt]

ohh, yeah....

[sharp harbor]

Hello, good day, I added leg ik foot placement and stride warping to my character, but my character's feet are digging into the ground and I can't figure it out. How can I fix it?

[trim matrix]

So small update, Inputs are being recognized but not playing my attack animations my combat idle animation plays but when I move its just my static combat idle pose rather than my attacks or walk animation

[naive elm]

Been editing a blueprint a lot. Now it started to randomly crash the engine when changing some variables in editor, how bad is this?

[void jewel]

What is the reason there is no possibility of using timelines in components? I see there's plugins for it and you can essentially recreate it yourself using timers etc. - but still curious why epic just didn't include this themselves? the fact that it's been so long makes me think there's some good reason to not use timelines in your components specifically?

[dusky cobalt]

did you try to restart editor and see? sometimes the errors don't pop up immidiatelly after changing

[naive elm]

of course, it crashes the project so I have to restart

[dusky cobalt]

im the worst when it comes to animations so I think i cannot help

[dusky cobalt]

any screenshots, what variables, where they are? did you try removing and re-adding them?

[naive elm]

just default vars that are defined in components that come with the engine

will change it, crash, reopen, change it again and it doesn't crash

totally random vars too

[trim matrix]

I'm very grateful for your help!!

[maiden wadi]

Crash it and give a crash report. It's impossible to say what the issue is without even a vague hint of where it's crashing.

Chances are you may need to install editor symbols to get a better crash report, but with luck maybe not.

[naive elm]

ill post it if it crashes again

[civic oar]

So I fixed what you said and there's still the same issue.

I.e. the Get node is now getting a reference and the dark blue dot is now a diamond

[maiden wadi]

Realistically. I would consider just saving an array of times. How you display it in UI is an issue for UI. And I say that because you have to separate gameplay and UI.

Your gameplay class should just say This is an array of times.

The UI can display n entries and fill as many as it can and display -- or whatever for non filled ones.

That is also to say, your UI should never store gameplay state either. So your times should go someplace more gameplay related. Either the playerstate, GameState, Car, some LapManager, etc.

[civic oar]

Yes, that happens elsewhhere in the VehiclePlayerController. The blueprint class im working within is the VehicleUI, the HUD

[maiden wadi]

The VehiclePlayerController has an array of your times?

[civic oar]

Yes, stored in a class called Lap

[maiden wadi]

Do you have any event dispatchers that run when a new lap or whatever is added/updated?

[civic oar]

The event dispatcher happens every time the driver hits a split, a checkpoint essentially.

So yes essentially

the event dispatcher just sends with it a split time, a string

But I could modify that if that's related to whats going wrong

[maiden wadi]

So your UI could bind to that and do an "UpdateDisplay" function whenever it's called and also at construct and just pull the active state of the laps and display them.

A single textblock could display what you have their currently as well.

[civic oar]

How do you create a new line? Im trying to have each event in the feed on its own separate line

{Linebreak} in format text?

[maiden wadi]

In a single textblock? You just format it. You pick your lap times and just format each line in. Like...

[civic oar]

Got it

[maiden wadi]

You end up with something like this. Set up the loop for how many laps you expect to see, etc.

If you want more complex displays, intro animations, etc. You should look into DynamicEntryBox for a dynamic setup where each line is it's own widget, etc. But this will be an okay start.

[lofty rapids]

does this not pull from the get even if its invalid index ?

because it's pure select runs both no matter what ?

[maiden wadi]

Ah, yeah probably. Branching it is. 🤷‍♂️

Unless you like log warnings. 😄

[trim matrix]

Def seems like my transition rules for my state machine are wonky at best, it'll play the animation no problem but wont smoothly just go back to combat idle after playing an attack animation

[formal talon]

I'm new to Unreal and want to make a tower defense game. Can you recommend any YouTubers?

[maiden wadi]

It's worth a note that you don't usually play things like specific attack animations using the state machine.

[trim matrix]

I was looking into animation montages

[maiden wadi]

The StateMachine is mostly for like.. General stats. CrouchIdle, Crouched, Walk, Run, RunWithWeapons, WalkWithWeapons. That sort of stuff.

And yeah, Anim Montages are what you'll use to play a slotted animation on top of your state machine so that they blend together.

AnimMontages are for like, attacks. Or like cheers. Gun shooting kickbacks, sword swings, clapping, etc.

Like you should be able to walk and do all three of those things, so you need your state machine moving the parts the montage doesn't override still and the montage does targetted animations on top of the state machine.

[trim matrix]

I did see that you'd add sections to make sure the attacks flow together

And unreal just knows when to stop the attack and stuff?

[maiden wadi]

It's based on the montage asset you create out of your attack animation.

I haven't personally gotten heavily enough into it to mess with like attack interruptions and such like if you swing and something happens halfway through like a parry, that kind of stuff. But I imagine it would essentially be stopping the active montage and playing another. But how you handle that kind of stuff is heavily dependent on your ability system. I'm not sure if Oblivion is using GAS or their own ability system, like what usually constitutes an "attack". These are usually wrapped inside of an ability that plays the montage and such.

[trim matrix]

Gotcha gotcha, thank you very much

It's been so challenging, fun, and rewarding diving into all this UE stuff

[maiden wadi]

It is certainly an experience. 😄 Sometimes great, sometimes terrible.

[unkempt plover]

I shrunk my blueprint nodes into as much of a packed space as possible so that I can capture this in one picture.

So what im making is a bird that will fly away when you approach it. On the begin play I've put a 40 second delay so that I can see it fly away. The problem is instead of them moving upwards (vertically) it moves horizontally

[unkempt plover]

ok so I made a mistake, as in I didn't notice that only these 2 parts of this code are being executed

Now it's gonna look something like this

it flies away smoother, but still it's not flying upwards

[full badge]

the default navigation doesn't support flying movement

so it still acts like it's walking

[unkempt plover]

what would we use instead?

[trim matrix]

Just wanted to update and let you know I got inputs recognized and my attack animations playing ingame!!! Thank you, AmberLeaf, and Engage very much!

[maiden wadi]

Nice. 😄

[full badge]

you need to do custom flying navigation

if you don't need the bird to avoid obstacles you can just do add movement input

[unkempt plover]

the obstacles part isn't really a problem... they are not to be controlled by me, isnt movement input the thing you use when you want to control a character?

[keen sun]

I want to work on realistic car drifting phyiscs but there isnt much content available on this topic can anyone help if they have any experience or their know any available resources that are helpful

[dusky cobalt]

Ok, this one is funny.

I have Actor with a BoxCollision that should affect NavigationMesh. I put it in the level, but the BoxCollision Extent first is set to size (1,1,1).
On Begin Play it should be updated to whatever size it should be (from data asset).

The problem is, it doesn't update the affected mesh?

The 2nd photo is after BeginPlay, you can see the square (it's the modified size, which is like 50,50,50), but the affected navigation mesh doesn't change.

What is funny is that If i put on begin play to Set Actor Location (same x,y) and Z +1, it will work. Do I really have to hack it that way for the nav mesh to register the new 'obstacle'?

[unkempt plover]

I dont understand what the problem is but I have a problem with nav mesh rn too. My problem is it doesn't generate on the landscape, but generates on trees just fine, it was working 2-3 hours ago, and then it suddenly broke and now its ignoring the landscape, I also scanned every forum post on google and couldnt find any solution that works

the green part generates on top of trees at the very top but not on the bottom of my flat landscape

could you explain again what the issue is with this problem you're having?

[dusky cobalt]

So as you can see on the first picture, there is a small red area. This small red area is caused by the CollisionBox (but it's so small you don't see it yet).

Then this Collision Box actually gets resized to 50,50,50 (yellow box in 2nd picture). This is the thing that should affect navigation, but it doesn't update the area (it should be bigger).

Finally on the 3rd photo I hack the system by Set Actor Location on begin play, which actually refreshes it and finally registers that this big box is affecting navigationm mesh and so now you see the area around is bigger as it suposed to be, kind of.

@unkempt plover

For your landscape, I have similiar problem I think, but i'm not s ure what was causing that. I created new level with new ladnscape and it started to work, You have to set it Used For Navigation that is for sure (but it doesn't help in my level that was bugged).

In the bugged level I also copied landscape from other project so it might be it.

[dusky cobalt]

did you also run Build Paths?

[unkempt plover]

yes I havent tried that yet, I think I'll copy-paste the level into new, and rename the 2nd one so that they dont have the same name, UE's (5.4) is kinda weird with levels

if you copy paste they can have the same name and if you delete one it deletes both etc.

[unkempt plover]

where?

[unkempt plover]

still nothing

it generates like this

[tight pollen]

some ideas

reference also is ok

[dusky cobalt]

hmm

[unkempt plover]

query only? query and physics?

[dusky cobalt]

It doesn't matter what is the collision settings because it works, it's just that it doesn't automatically update without moving the actor.

[unkempt plover]

why do you want to update it?

[dusky cobalt]

because it's dynamic for every actors based on data asset variable

like every actor will ahve different dimensions

measured in tiles... so one is 2x2 one is 1x1

and i'm updating it live, but without hacking it's not auto

[unkempt plover]

so you use blueprint to update the nav mesh level component?

maybe trying this could also solve my problem

[dusky cobalt]

no, I just have to Set Actor Location to the literally same location 😄

[unkempt plover]

ok so you refresh the actor itself and then it works?

🤔

sounds very weird

[dusky cobalt]

ye it updates the Obstacle area..

like look this is if i hack it

and this if i dont

doesn't register the Obstacle area around it

but for your issue try to create new level and just put navmesh and click P

[unkempt plover]

yes I did and it didn't work

[unkempt plover]

can you export me your own nav mesh settings from your own ue project?

someone on reddit fixed it like this

[dusky cobalt]

he exported it from the fresh project

[unkempt plover]

yes but my nav mesh on my fresh project also doesnt work

so its likely that my global unreal engine nav mesh is broken

maybe I need to uninstall unreal engine and re-install it? Im not sure if that would fix it. I tried everything literally

[dusky cobalt]

i dont think so, because it works on the trrees instead of land basically

so it works, jsut has weird settings

maybe you need to modify agent radius or something

[unkempt plover]

yes I tried that too

maybe i need to download another unreal version

I need to exhaust all the possible causes

ok it works on a new level

ok now it works

that was just a weird engine bug

I had to open a new level and add a nav mesh there, so now it will work on your main level

[crude hearth]

what am i doing wrong i just want that my equip animation will take as long as the equip time of the weapon

[dusky cobalt]

unforutnately didn't work for me but I found this 'solution' on reddit as well 😄

[narrow sentinel]

bit of a stupid question here but how would I input sensitivity in this so the mouse vertical movement does or does not affect as much the movement

if that makes snse

[lofty rapids]

Your sensitivity variable should be what you want to change

This is you speed of movement

[narrow sentinel]

so the it's instance editable but from what I can see it does work but only when it's between 0 to 0.2 ish

[unkempt plover]

question... I have a blend space here...

it goes from idle, to walk to hop.

but the problem is I never see my bird walking, it just slides and the animation is frozen
but the idle animation works when its not moving

[full badge]

just try to turn off collision of it and turn it on

should update navigation

[dusky cobalt]

like on begin play?

[lofty rapids]

if you change speed in the animation, do you see the preview of it walking, or hop based on the number you put in ?

just hardcode the speed to test it

hey guys, I had a quick question. I am working on a vr project where the disc (checkered) is around the player. The idea is to make it rotate with the oculus left joystick controller. I must say I have no experience with vr and blueprints for interactivity but basically I want to have smooth rotation when the joystick is interacted with and stop in whatever position is was when the player stops interacting with it. I used gpt 5 and gemini 2.5 pro but they can only get me so far. Could someone help me out please? Thanks in advance! ❤️

[lucid ore]

*when I compile i get no errors but it still does not work. GPT told me to use a get player controller on event begin for the vr pawn but i cant seem to find that specific blueprint, only get player controller id and another one

[inland walrus]

Is it possible to make the mouse the target some how but only on the X & Y? I want my niagara to follow the mouse and leave trail etc and setting the location glitches the trail

I basically need to replace sprite with mouse

[rare venture]

Is there a node that gives me the value of INT_MAX?

I can’t find anything in the docs the mentions something like this so asking here

[maiden wadi]

I don't recall there being one but I could be mistaken. I've always just coped it into a literal int node.

[maiden wadi]

Need more context on what isn't working. Just to note, you're adding the same IMC_Default twice in a row. But have you put prints on your IA nodes like where you're rotating the disk to see if you're getting any input at all?

[maiden wadi]

Short answer: No. But what you can do is either update a vector in the system on tick. Or create a second component and pass that to the target like you're doing now and move that to the mouse location on tick.

[lucid ore]

True I just realized its twice. The issue is that the disc is not rotating on command although everything else works

[maiden wadi]

This is also an issue if you haven't hooked this up since screenshots.

[lucid ore]

I see its because i used gemini. hmm any direction on how I could connect it? I hope its not too complicated since I dont want to take a lot of your time either

or any resources I could look up for something similar

[maiden wadi]

You just need to connect the white triangle from the UpdateRotationAxis to the Set node

[lucid ore]

omg haha damn

[maiden wadi]

Your Set node has no execution here, so it won't execute.

[lucid ore]

oh my it works! Thank you soo soo much

[maiden wadi]

🥳

[lucid ore]

i spent 3 days on this..

hahah cheers all the best to you

[maiden wadi]

Welcome to gamedev. 😄 You'll spend three more days on something derpy shortly in the future too. Seems to be a constant.

[inland walrus]

I did this but it only works on the ground axis

[maiden wadi]

Hmm

[rare venture]

Looking over it and the docs it appears there isn't one. I just exposed my own function as a bp library but kinda strange this isn't something already exposed. x.x

[inland walrus]

I did this and it works but the plane doesnt move with the camera

so if I move away from the plane, the niagara stays in its place

[maiden wadi]

You're gonna repeat that sentiment a lot. There's a lot of "why isn't this default?" in the BP API. 😄

[maiden wadi]

What I would do is use the other function it's a little more clear. Half sec, I need the editor open.

@inland walrus Oh, right I updated main branch. Oof. Okay. We'll do it from memory. Uh.. There's a node called.. Line Plane Intersection (Origin & Normal) I think?

It's similar to the one you're using, but you can specify a plane location and direction easier than using the Plane struct.

So you can make your character the plane origin.

[inland walrus]

got it, I'll try that, I just did this and it worked too

[maiden wadi]

I've never learned how to use the Plane struct. 😄 Probably should someday. Never had a reason.

[inland walrus]

xD, it seems to be working but now I need to figure out how to make it stay on the player screen and not get hidden inside buildings

[maiden wadi]

I think in RS2 we have some similar effects where our materials render on top of anything else. I don't recall how that's done. But it'd probaobly be the easiest solution ehre to make your particle materials do that. Otherwise you're going to be doing derpy projection and traces.

[inland walrus]

I've put a plane right in front of the camera and changed the W target. It works, now so I guess I just need to make the particle scale smaller

[maiden wadi]

This is what I meant by the material thing. The 0% Critical is UI. But the yellow text below it and the arrow with it are in world space. They're a plane and a text render. And they're actually underneath of those containers. If it wasn't for the late render material you wouldn't see them here. But that makes them always draw through anything. And we don't have to do complex placement.

[muted gorge]

Hi guys me again, I have an system in my mind. But it's really complicated because of my limited knowledge 😭. I don't know I should type it directly here, because I didn't get the copyrights, about the game mechanic. And if I send the idea, can somebody steal the idea? I'm really nervous about that

It's not like Inventory or other systems...

[maiden wadi]

Game design isn't about ideas. Someone's already had your idea most likely. Execution of ideas and a ton of work are what make games. And systems are whatever.

[muted gorge]

im pretty sure that this idea is never executed

right now

because I checked a lot and It's different from other games

where is rules channel tho I wanna check something

[maiden wadi]

I didn't say someone did it. 😄 I just meant someone has probably had it or similar. But either way. Systems are eh. Unless you're Nintendo and want to sue everyone.

#rules

[muted gorge]

Ohh

thanks for the channel

i will be bake

back*

okay I came back

so I can put a job volunteer thingy

but if people make theyre own game with the project details?

I'm really afraid of that

😔

im trying to develop the game for 1 years, im still designing the things and note them since 2023

all the effort 😔

[maiden wadi]

Someone made a project named Sekiro. Someone else made a project named Jedi: Fallen Order. They're essentially identical at their core. Gameplay ideas are cheap. What you do with them matters. If you have an IP, get it copywritten.

[muted gorge]

domains be like

hmmm

can I say that the some details are private for leakability/stealablity reasons

[sand shore]

What you’d probably be most interested in doing is getting them under contract, if it’s protection you’re after. You may be able to get them to sign based on rev share. You can claim the rights to all work they create (or allow them partial rights, for their use and portfolio, or even allow them commercial use) - and in that contract you can specifically stipulate that your existing works and IP derived from it are yours.

I’m not a lawyer or anything, but if you’re not getting an agreement like this, it’s going to be a lot more difficult to have standing if you ever need to sue.

If you can’t afford to sue, it’s pretty moot

But for general help inquiries, just share what you’re comfortable with

[sand shore]

This happens constantly in the mobile development space, but it usually happens even after games release.

[lilac storm]

Hi everyone, I need some advice on implementation.
I have a small market with NPC vendors, and each vendor should perform many different actions.
For example, a fish seller might:
Arrange fish on the shelves ,
Then place fish and go cut a different one with a knife,
Then maybe go clear the floor.
So basically set of actions where npc needs to interact with environment (fish,knife, mop etc and it should natural)

Should I create a series of Level Sequences for each vendor?
Or would it be better to use a Behaviour Tree for each one, considering I need many different vendors with unique sets of actions?
or there are other some better ways?

[maiden wadi]

Given the possible dynamic nature of this. I'd personally be inclined to start making smart objects or actors that prompt the correct behavior that can be placed near them and they can access. Maybe give them cooldowns and they can randomly pick or pick by priority, etc. This way you can simply link the behavior and do it for each one separately as a level designer. And your possibilities become endless as a designer. So in this case, behavior trees. Or more accurately one behavior tree that is tasked to go to the spot and perform the action.

[muted gorge]

THEY SUE PEOPLE WITH A FEE WHAT

ohhhhh

thats really good idea

thanks!

[sand shore]

Well they can

Not necessarily a good idea

You might not get much payoff

[muted gorge]

ohhh, okay

[proud bridge]

Hey is there anyway to mask the background blur available in UMG?

[maiden wadi]

Short answer: No.

But you can make your own now. There's a video showcasing it from.. I think Bitter Joyrock, I'll see if I can find it. She uses some new tools in 5.5 or was it 5.4? Where UI materials can access the draw buffer now.

5.4 I guess. 😄 https://www.youtube.com/watch?v=4ga0DDK1t0c

[proud bridge]

I am on 5.3 and ended up making a blur material with the mask. I ll learn this though. Thank you for sharing.

[faint pasture]

Nobody is interested in stealing your idea or working on it for free. Either ask questions about implementing it or figure out how to implement it yourself if you're so nervous about it being public.

[trim pollen]

Is it me or is the json package garbage? You can't have nested parameters, cant create a json file / has to already exist... is this a skill issue?

[maiden wadi]

Unsure what you're meaning? Never used a JSon package I don't think. I only use the JSon to and from structs stuff.

[trim pollen]

The json blueprint nodes are part of a package. It might come with ue by default, dont remember.

Sorry i mean plugin not package

I want to work on realistic car drifting phyiscs but there isnt much content available on this topic can anyone help if they have any experience or their know any available resources that are helpful

[muted gorge]

how can I input the object?

[pulsar osprey]

1. only a single branch is getting used there
2. what is being passed in the event? it looks like they are already player controllers

[muted gorge]

i fixed the single branch, the passed thing is controller type (old, new)

if the player uses old controller it gonna cast to player controller as old controller

if it is new it gonna cast to player controller as new controller

ohhh waitt

bruh, okay my bad

its old controller not "old"

my begginerless

Would anyone happen to know in which version of Unreal this feature showed up for running Editor Utility blueprint? It's there in 5.6, but wondering if it's brand new, of if it came sooner

[paper gate]

Ok I have encounted a bug that makes zero sense. I made a brand new anim notify state. Made a brand new variable and tired to add it to the graph to set it to a value
and its telling me that it cant because its "read only" If I just made both things fresh out of the box how is it read only? and how can I fix it

[icy jacinth]

I'm still having some trouble updating the parameters of the Material that's used for my healthbar widget. I've added the logic used to generate the material, the logic I'm attempting to use to adjust the parameters of the material in the widget, and a view of the distorted rendering. The two issues are:

1. The distorted segmentation of the healthbar -- I've narrowed this down to the Set Scalar Parameter Value node for Total Segments.
2. The parameters of the Material are not being set via the logic in the widget.

No texture is used in the material, and I've verified that the required variables (color, Healthbar MID, Max Total Health, etc.) are valid

[lofty rapids]

how do you know that node causes distortion if the parameter isn't get set ?

[icy jacinth]

That's another point of confusion, but when that node is skipped entirely (Then1 > Set Parameter [Base Health Segments]), the distortion doesn't appear.

[lofty rapids]

thats interesting

[icy jacinth]

(Also I couldn't find a node for setting a dynamic texture based on your suggestion yesterday, but I'm currently creating a dynamic Material Instance in Event Construct and binding it to the slate brush of the image component)

[sharp harbor]

Hello, good day, I added leg ik foot placement and stride warping to my character, but my character’s feet are digging into the ground and I can’t figure it out. How can I fix it?

[lofty rapids]

yes dynamic material instance, then you can use that you set the material on the mesh to the instance, then you can set the parameters

[lofty rapids]

are you spawning in like this ? try to raise your character up a bit, or what does it look like in your viewport of the character bp ?

[sharp harbor]

I tried moving the character up in the character blueprint, but it didn't work. I got frustrated and started the whole project over again. If it doesn't work this time, I'll ask again. Thanks for your help.

[unkempt plover]

So I tried something like this yesterday and it didn't quite work... #blueprint message

Today im using this method to get my bird to fly, but it just disapears

[unkempt plover]

I was already using add movement input in that screenshot
