blueprint

[frosty heron]

You need to load them via async load object or blocking load

The idea is you should load them before use.

And if you think sometime some of the material work, is because you may open the asset in the editor at some point where they stay loaded until you restart.

[gentle urchin]

(Wish we could turn that off^)

[proud salmon]

If you have a function that uses the Async Load Asset node with another function called off the "Completed" node.

If you call that function a second time before the first has finished loading, will it still run both "Completed"s?

[gentle urchin]

If the asset is different , yes

Unsure if its the same (kinda doubt it)

[midnight field]

Is there a way to check what level/world I'm currently in?

[obtuse gale]

There's a blueprint node "get current level name", if that's what You mean 😄

[midnight field]

Ah, that could be what I'm looking for! Would this return a persistent or streaming level?

[obtuse gale]

To be honest I'm not sure, maybe someone more advanced can tell 😛 There's also a bunch more nodes that might work for You

[midnight field]

Thanks for the leads! Basically I'm trying to create a gateway between levels, and I want to ensure that the persistent world is loaded before loading the streaming level.

[obtuse gale]

No problem, I'm trying to help someone out in return for others helping me here C:

And I have a question as well. Is it possible to "break" physics object out of its default position only, when force big enough is applied? I can't apply force to object that's not simulating physics, so I can't use "set simulate physics" to achieve that

[midnight field]

Hm... wish I could help on this, I did this kind of thing in Unity but the solution was rather hacky. I suspect Unreal might have some options for it, but it would probably involve giving a class a scripted collision response.

[gentle urchin]

Custom force filtering

Just wrap the regular force function with a preliminary check

If InComingForce < x set IncomingForce to 0, else leave it alone

[trim matrix]

Does anybody know how i can make so that it adds the lsit of music to the array for playing in ue5. Btw im new
https://blueprintue.com/blueprint/mctmm82s/

I linked the blueprint code

[plain jay]

You could create a custom add force node in a function library, that will simulate physics before applying the force maybe? Assuming you're not using hit events

[mellow pike]

thanks the print test worked with that
here is were im actually using in (in a macro)
just need to see why I cant set it to the array 🤔

[inland tide]

Solved!!!

[dark drum]

When you load anything, the returned object is that of uobject so you'll need to cast to the relevant type. In this example it looks like a texture 2d.

As an FYI, you do need to include the load asset blocking in the execution path though.

[rocky kelp]

I don’t know if anyone else has had this problem, and I’m not sure when it happened by my character is suddenly not able to move. I clicked on the character movement component since errors were occurring when I tried to play and there is nothing in the details panel. Is there even a way to fix this?

[maiden wadi]

Persists even if you restart the editor?

[rocky kelp]

Yes

[maiden wadi]

You can try downloading and using this. It's most likely that the pointer to the movement component messed up in the BP. Needs set back to it's component.
https://brandtborges.wixsite.com/authaer/post/fixing-corrupted-blueprints

[gentle urchin]

Damn, neat!

[maiden wadi]

It's wild how common that issue is. :/ Kinda wish there was some way to lock down that pointer better for serialization purposes.

[copper chasm]

anyone know why in the heck when i drill into a bp, the viewport and event graph are not on the same page? like, I have to drag the tab up every time

[fading sail]

so I spawn various kinds of animals at runtime (ie not placed-in-world at edit time) but what I spawn each time is a single "BP_Animal" instance (custom BP class that inherits Pawn) that is initialized with a random-selected-from-a-list Skeletal Mesh and its associated (idle) Anim Sequence.

(the 2 asset packs for those 12-or-so different animals basically both have for each animal: Skeletal Mesh, Physics Asset, Materials, various Anim Sequences.)

of course, now I want sth like IK so that initial placement on sloping ground (it being never perfectly flat) is without the too-high-or-too-low foot placement, and then also hoping to AiMoveTo those Pawn-inheriting BP_Animal instances to random locations, setting the walk anim when movement starts and back to idle when it stops. (no anim-BP stuff, just "Anim Mode" setting set to "Anim Asset" and the applicable Anim Seq being set. good enough for this "backdrop decoration non-gameplay purpose".)

if you had this kind of random-selected but single BP class spawning setup, not wanting to give it up either, how would you bring about IK-or-IK-like "automatic limbs placement" for the initial, just-spawned, idle-anim'd skeletal-mesh, and also keep it going during the animal's subsequent terrain traversals and future idlings at new spots?

[rocky kelp]

Is there any other way to resolve the issue, i am so confused

[gentle urchin]

Just go with procedural animation 😅

[maiden wadi]

Recreate the entire BP or source control.

[gentle urchin]

Cant you setup shared IK in anim template instance nowadays ?

Shared anim instance or whatever it was called

[fading sail]

thx @gentle urchin dunno if I even have "anim instances" here, seeing how I just set a Skeletal Mesh Component's mesh asset and Anim Sequence (ie no Anim BPs etc) 🤔

[gentle urchin]

Id suggest making an animBP in that case

Those can run off gamethread aswell these days (i assume that includes for the IK resolving?)

[mental trellis]

Oh, it's the tail!

[frosty heron]

Because it returns the most generic class (object).

You will need to cast to the type, what ever it is.

E.g. texture 2d, skeletal mesh, yada2

[mellow pike]

"you do need to include the load asset blocking in the execution path though. " yeah I just took the screen shot when I saw the pin did not connect .

thanks guys

[mellow pike]

yeah I picked up on that by the fact a cast was needed, but good to get the confirmation .

thanks again for helping me learn the quarks

[frosty heron]

just know that load blocking will block the game thread

if you loading a lot or heavy object, your game will hitch/freezes

the other way is to load Async, which most people probably use? I personally don't like the idea my game thread will be blocked just because I want to stream some visual stuff

[autumn pulsar]

Is there a way to print an array of objects as a string?

or view what objects a variable is holding?

[frosty heron]

you mean like get the names? of course

not sure what view what objects a variable is holding mean

maybe post your code

[autumn pulsar]

https://i.imgur.com/DMR1kfO.png

trying to debug this nightmare

for some reason, it's getting the distance of a different actor but is still setting the closest actor variable

https://i.imgur.com/AsyyOB2.png

for some reason the distance is being set to 20000, but it's still following the flow where it should be set

https://i.imgur.com/gOaUA74.png

[frosty heron]

reading other people code and math is not my forte, sorry

can't say I really understand what's going on

have you tried break points?

[fallen bluff]

hey everyone, i followed the ue documentation to add a custom character to my game animation sample project, however that only adds it to the in game widget
does anyone know how to set that custom character as the default one instead of the sandbox character?

changing the default character blueprint just messes the animations up for some reason, unless i did something wrong

[autumn pulsar]

Okay, found out my issue

I shouldn't be resetting the closest actor distance during the for loop, but rather before the loop

[autumn pulsar]

in the world settings you can set the "default pawn object"

you can also set it in the gamemode

[mellow pike]

yeah i will keep that in mind. its fine in this cases as that code will only run while setting equipment (more less) it will not run in a fight or any thing that that could mess with. but i will keep it in mind

[fallen bluff]

thanks man

[normal narwhal]

Hi, i try to make a game that require destroying walls, but for a bit of realism i try to make the bullet that touch the fracture only destroy the fracture and not the whole wall

[mystic edge]

Hey guys, just wanted to ask if somebody knows how to make or knows a good reference for snow thats deformable by for example footprints (so the shoes like sink into the snow). It can be low poly also. Thanks!

[austere matrix]

Are you just trying to get the nearest actor from a sample of actors?

[autumn pulsar]

nearest actor within a cone in front of the player

that also fits the "interactive" criteria

[austere matrix]

Ah, I see

I ended up just ray marching down a line trace and giving each interactable a score based on the distance to the current point in the match

[autumn pulsar]

There's probably a way better way to do it

and I should trace to make sure I can actually see what I'm interacting with

[zealous moth]

@frosty heron For vrm what goes best with cel shading? Lit? Sss? Or does it not go well at all? I'm testing several cel shaders and none seem all that great...

[frosty heron]

I'm using lit but you have to tune them to make it look good.

don't know what settings, my brother does them.

I only add more support to add more layers for Tatoos

[zealous moth]

Do you have any cel shaders ppv or use environments as is?

Lucky brother 😛

[frosty heron]

No PPV afaik

i can take SS

[zealous moth]

Lit on regular environment?

[frosty heron]

Yeah but you can't take 100% light imo

that do look shit

[zealous moth]

Isn't that odd or jarring?

[frosty heron]

the mesh will be too 3D

that's the issue with cell shading material imo, at least the way I got it setup

the environment light doesn't really affect the character mesh

good luck trying to setup cell sahded graphic with pure black areas

Your main source of light is the fake direction

[zealous moth]

Well I got a few and they work OK ish

[autumn pulsar]

https://youtu.be/eBS3BOI5KnM

This video is pretty thorough

[zealous moth]

I was wondering how sss or ssp with regular realistic looks but it's meh.

I tried 2 good celshaders and this was one but it sucks for reflections

Wow, no cel. How did you get that lighting? Camera based spotlight?

[frosty heron]

Directional lighting based direction

I am just after 2 things

the base color and the shadow color

[zealous moth]

The list vrm seemed to do the job, no?

Lit*

[frosty heron]

yeah but you have to tune the settings

out of the box, looks pretty shit to me

[zealous moth]

Like what? The mat cap?

[frosty heron]

The lit version out of the box, will give you the bottom one I think

[zealous moth]

Looks like sss

Top is lit with pseudo shadows

[frosty heron]

This is soo nice! Looking like Girls frontline (from the same page)

[zealous moth]

But I meant more the environments. Trying to reconcile the styles is hard

[frosty heron]

yeah pretty much

[zealous moth]

Ooh nice effect I was gonna learn more on that but I'm still struggling getting the styles to work.

I have a pretty realistic setting and sss just looks weird to me. I'll look into different other cel styles. I think I have to kill reflections. Lumen just can't do it right

[frosty heron]

for the environment, we rely on hand painted textures

giving outlines

don't take too much lighting (more emmisive) then call it a day

[zealous moth]

Thinking that too, hence cel.
I saw that miside was doing it well

[frosty heron]

that looks nice

[frosty heron]

good stuff, ty

[maiden wadi]

What steps did you take besides the ones you outlined here? Such as specifying it in the GameMode, etc?

Any reason not to use the game mode's setting if it's the default character? I'd also introduce a delay to see if that fixes anything. Initialization stuff can be weird sometimes with default possession and the like.

[steady night]

Hi, auestion about AI” focal point, where dosenit update ? Can i disanle it while playibg montages or manipulate it somehow?

[maiden wadi]

Depends on what's setting it. You can set it explicitly, or you can also set it to follow an actor. And if I recall there is a layered priority thing there.

Why do you need to disable it for montages? For like not not rotating the AI towards their focus when playing the montage?

[gentle urchin]

sounds like something a notifystate might handle,

but if its across all montages, it might be better to just add the logic in the AnimBP

but.. its AI specific ?

[maiden wadi]

Was mostly just thinking that you'd simply disable the pawn's use controller rotation. Would work regardless of controller type.

Since that's all the focal point really is is a way to modify the AI's control rotation to "look" at something.

[gentle urchin]

isnt that the thing people override aswell to give AI a more dynamic sight sense?

[maiden wadi]

Override?

[gentle urchin]

hmm no im thinking of another thing

GetActorEyesViewPoint, not even close

to early, no coffee, ignore me

[maiden wadi]

There's a GetFocalPointOnActor. Which you can override to point to specific places on an actor. By default it just uses the actor's world location.

[steady night]

Exactly

[maiden wadi]

That's if you're using SetFocus and not SetFocalPoint though.

[maiden wadi]

If this was in reply to the rotation thing, then I'd consider just toggling the pawn's use control rotation setting off during the montage. Like Squize mentioned through notifies maybe.

[steady night]

Im setfocis

Oh yeah that might be best 🙂

[frosty heron]

does anim notify state guarnteed to play?

lets say if your frame rate is too low that you "skipped" the ans

or does the begin and end of the ANS will be called with guarantee?

[maiden wadi]

Unsure on animations. That's one of my weak points. If it uses the same sequencer code as UMG tracks then it will.

[gentle urchin]

even when happening on the same frame I'd suspect

[frosty heron]

I hope that's not the case. I spent quiet a bit of time trying to setup actor to bake anim data to anim notify state

[maiden wadi]

The UMG stuff at least is pretty solid as far as making sure events are called regardless of framerate. There were some fixes to that early in 5.0 I recall....... 4.27 not so much.

[steady night]

When setting the use controller rotation on/offf then the npcs snaps back to target after animation which looks super bad… ideas ?

[maiden wadi]

I have some interesting little hacky checks after animations in red solstice 2 because of that. :/ Widgets getting stuck just before their last frame.

[gentle urchin]

Some day I'll have to do something proper with movement...
AddMovementInput((TargetLocation-GetActorLocation()).GetSafeNormal2D(), FMath::Max(Distance/100.0, 0.01));

[maiden wadi]

Isn't there a setting that makes the character rotate at a speed towards it's control rotation? It's been a hot minute since I've worked on my RTS stuff.

[gentle urchin]

yes there is

[steady night]

Hmm

Still snapps :/

[gentle urchin]

it's just sliding rotation but that's ofcourse another matter

[steady night]

Is the setfocus not ”setting” the rotation rather then lerping ?

[maiden wadi]

SetFocus doesn't actually do anything to the control rotation itself. It just updates what the AI should focus on. There's code somewhere...

[steady night]

Use controller desired rotation

Use rotation to movement

[maiden wadi]

Oh. Huh. This is always true. Which will call..

Bit odd code..

They passed Deltatime here and never used it. :/

[steady night]

So cant make it base on rotation rate instead :/ ?

[gentle urchin]

override?

its virtual

pff 😄

[maiden wadi]

Yeah, you would need to override this in your own AI Controller.

[gentle urchin]

or pawn ?

[maiden wadi]

Or pawn, yeah. Got mixed up, jumped back to the UpdateControlRotation 😄

[gentle urchin]

hmm

its only called from AIController

[steady night]

Y

[gentle urchin]

so its using the controllers deltatime

interesting

[maiden wadi]

👀 TODO hell here.

[gentle urchin]

ouf 😄

[frosty heron]

some of the comments from epic doesn't spit confidence

it started with

// Boy oh boy is this a dirty hack, but I can't figure out a good way to do it otherwise at the moment
// The UniqueNetId is an abstract class so I can't exactly re-initialize it to make a shared pointer on some functions
// So I made the blueprintable UniqueNetID into a dual variable struct with access functions and I am converting the const var for the pointer
// I really need to re-think this later

[maiden wadi]

I'm not sure I'd override the FaceRotation though. This is a weird one.

A lot of things rely on this to set rotations explcitly. I'm kind of curious what led to this function anyhow since it's basically treated like a SetActorRotation call in a lot of cases.

I feel like I'd be more inclined to override UpdateControlRotation in the AI controller and lerp the rotation from current to the target focus location.

[gentle urchin]

Yeah im inclined to agree

lucky i dodged this crap 😄

[steady night]

Haha ok so… what do u want me to do this is above my paygrade

[gentle urchin]

get a raise

sorry, not helpfull lol

[steady night]

Ha story of my life

[maiden wadi]

Make the AI programmer deal with it. 😄

[gentle urchin]

swaps hat

[steady night]

All me ma dude 🫠

[gentle urchin]

https://tenor.com/view/hats-michiru-michiru-kagemori-bna-little-witch-academia-gif-20586687

[steady night]

I mean i can think of workarounds but they are messy

By tiggeling use controller roation on/off i could just lerp and set the rotation towards the target before turning it on again i suppose

[maiden wadi]

This is a super strange assumption... Imagine trying to shoot something on the ground, or high up on a wall, by making the AI aim at it and wonder wtf they're doing shooting lateral.

"I CAN'T LOOK DOWN AT THE CRAB BITING MY ANKLES! IT WASN'T A PAWN!"

[steady night]

🫠

Also another question, im all new to behaviorbtrees thats with these questions regarding Ai, so i got the sample im mixing with to learn, the ”move to node” has an acceptable radius, is there s way to set that per npc or do they need their own specific treen?

[gentle urchin]

you'd need a custom task which reads the radius from the controlled pawn

you can't afaik set it per instance of BT

and getting it from the controller seem weird to me

[steady night]

Yeah im in the woods dont have internet on my laptop lelz, @frosty heron

Ok so how would i do that or should i justvwatch a tutorial ?

[gentle urchin]

creating a custom task should be fairly straight

you can 95% copy the existing one,

and just alter the acceptance radius from a parameter to a read from controlled pawn thing

[steady night]

Ok ill try

[gentle urchin]

I realllly wish DA gave me better controll over the GridFlow nodes

[maiden wadi]

GridFlow?

[gentle urchin]

one of the map generation types

DA - Dungeon Achitect

I want better control of everything

[maiden wadi]

Ah. Saw that a long while back when I was looking more into Prefabricator. 😄

[gentle urchin]

paths, spawning rooms, sizes, algos...

the main roads have a high likelyhood of just snaking up on itself

[maiden wadi]

Seems like everything's price has gone up on FAB. I recall DA being less than 100 euros.

[gentle urchin]

I was hoping to use this to get away from my own custom thing

But I must admit.. I expected more flexibility and control from it

I can't even control the width of the "paths"

or size of the rooms

There's no node to even spawn a room explicitly, it's just part of some other node

[maiden wadi]

Very flat minded too. Doesn't seem to allow overlapping areas like paths going over other areas?

[gentle urchin]

the layouts are specific to the 'mode' you're using

you can use snap flow with 3d support

e.g. room above another room

but that requires predefined rooms and corridors

im currently 'hacking' it together by using multiple main paths and gambling on some luck in stitching them together with some alternative path

but it feels really fragile already...

Doesnt always build

rooms are very s quare

[maiden wadi]

Needs more bombs.

[lost hemlock]

Does anyone know why is it that when I run this, the loop body doesn't print something like:

1
2
3
4
5
6
7
8

Instead it just prints:
8
and thats it...

[gentle urchin]

So im stuck between trying to get this to work, or rolling custom...

[lost hemlock]

Same thing if I do this

[maiden wadi]

Key.

[gentle urchin]

feels weird having to roll custom with a high value asset like this one

Or maybe I'm just using it wrong

[lost hemlock]

what do you mean?

[maiden wadi]

The Key is set. So it will only print the latest thing that key tries to print.

[lost hemlock]

https://youtu.be/_9btL0_yH8k?t=724

It's supposed to do this, isn't it?

[maiden wadi]

Change Key to "None" without " and run it again.

[frosty heron]

one thing I hate about marketplace stuff

but I do learn a lot from some of them. At the end of the day I just re-create it X_X

[lost hemlock]

I don't have a key, if by key you mean the section size or section count?

[frosty heron]

started with Dynamic combat system, that really gave me insight on inventories and how combat is conducted

[lost hemlock]

oh

thank you

[gentle urchin]

It does include a 'custom builder' section and I caaan extent the plugin but.... at that point, isnt it the same work?

in some sense it's actually worse because i still need to play with the plugins rules instead of my own

[sour smelt]

So I was working with live link in ue5 to parse the data to a meta human , I want to make a trigger in blueprints to know if the live link subject is active like the yellow turns to green , so there was a node is live link subject enabled but it just returns true if there is a subject in the source and not when it is parsing data , is there a way to know if the subject is parsing data or not in blueprints?

[swift falcon]

What they are suggesting is wrong. Turn off orient to rotation and turn on use desired rotation. Do not override anything configure the rotation rate now

[steady night]

Yeah but its the snapping after thats the problem

[normal narwhal]

Hi, i try to make a game that require destroying walls, but for a bit of realism i try to make the bullet that touch the fracture only destroy the fracture and not the whole wall

[dark drum]

Have you looked at wave function collapse? It might be a good base that's less fragile.

[frosty heron]

How can I rotate a point by a degrees?

[gentle urchin]

I have not, ive only experimented with random rooms and some basic placement

Im unsure or the implementation time for WFC 😅 dont wanna spend half a year on it

[lost hemlock]

Why is my selection indicator leaning towards a little bit to the right, even tho it should be exactly on top when you set it on 90? This is instead getting set at the right position when I set a number smth like (about) 112.629662 on the active rotation

[frosty heron]

I need to rotate these points by one the character axis, any help? 🥹

Soo close to make this work.

[lost hemlock]

This is from the tutorial where he does the same thing and it works

https://youtu.be/_9btL0_yH8k?t=1289

[gentle urchin]

Point? Direction? RotateVector

[dark drum]

From the very limited videos I've watched, a few days to get something crude setup. It could be a good way to define what the general tile is then use another system to add the decorative fluff to it.

[gentle urchin]

How much controllability does it give😅

[frosty heron]

Is it GreaterGreater_VectorRotator?

[gentle urchin]

Uhhh

Which graph are you in

[frosty heron]

I double click rotate vector and I think that's where it take me

UKismetMathLibrary

[gentle urchin]

ohh

in cpp land

[frosty heron]

[gentle urchin]

Yepp, that's the one

[frosty heron]

hmmm

I don't know where my trace went

oh well, gotta figure this out

2 more hrs before sleep

[gentle urchin]

wait

there's another one

rotate vector around axis

if that's more appropriate

.RotateAngleAxis

[frosty heron]

🤔

I was hoping I can just Rotate it by the actor's rotation

using the previous node

will see what I can do with this one

[gentle urchin]

that might be enough then ^^

[frosty heron]

but it;'s missing 😔

[gentle urchin]

oh hold on

its your traces

[frosty heron]

UKismetMathLibrary::GreaterGreater_VectorRotator(ActorOffsetLoc + MeleeTraceData[i-1].SocketLocations[x], MeshComp->GetOwner()->GetActorRotation())

^ Don't know where it went

ActorOffsetLoc + MeleeTraceData[i-1].SocketLocations[x]

^ The point is there but not rotated correctly.

[gentle urchin]

being on the wrong side of char?

[frosty heron]

the traces are fixed

they are baked from animation

[gentle urchin]

Ahh fancy that!

[frosty heron]

so when using it, I need to rotate it by the actor rotation

[gentle urchin]

hand it over, rn!

/jk

[frosty heron]

I would probably make tutorial if it work, still need to test for real

[gentle urchin]

what does a trace point look like ?

you're already offsetting by location i take it

[frosty heron]

Yeah but im only offsetting by the actor location

one sec

[gentle urchin]

right

but rotation needs to happen in local space

so the in vector of the RotateVector

is the local Vector

just in case

[frosty heron]

Hmmmmm, let me process that

[gentle urchin]

so the original baked data

needs to be rotated

then added to the actor location

in that order

[frosty heron]

oof, but I wont be able to do that since the rotation in game time could be anything

[gentle urchin]

isnt location also the same?

[frosty heron]

the location is Bone Location in world space - Actor location in world space

Im trying to get the bone location in respect to the actor location

[gentle urchin]

ActorOffsetLoc + MeleeTraceData[i-1].SocketLocations[x].RotateVector(GetActorRotation())

[frosty heron]

so that part is fine, it's just the rotation

man, you are such a savior. Let me try that.

there is no .RotateVector =(, which method does that belong to?

oh wait

I get what you mean

[gentle urchin]

I assumed SocketLocation was a vector

[frosty heron]

🤦‍♂️

one sec

yeah it is a vector

I don't know why I rotate the ActorLocationOffset lol....

that must be my mistake

[gentle urchin]

you shouldnt rotate the offset

[frosty heron]

@gentle urchin

[gentle urchin]

Glorious!

[frosty heron]

thanks to you I can do the dishes tonight

work at any fps

but i have bigger problem, the input buffer system I have been building. They break on low fps

player can't do the combo because the window to enter the input is too small

[gentle urchin]

Its a hard problem to fix

[frosty heron]

just gotta tell those poor souls to get better pc

[gentle urchin]

Well... does it work at 20fps ? 😄

[frosty heron]

the trace works but the input break

kinda unrelated system

[gentle urchin]

Yeah i ment the input

[frosty heron]

yeah it sort of work at 20 fps 😢

might have to spam a bit more

[gentle urchin]

20 might be the lowest 'acceptable' point where things should be 'playable'

Oh so its a short input window?

[frosty heron]

yeah 😔

I could probably improve it just like this trace system

[gentle urchin]

Some notifystate thing?

[frosty heron]

yup

[gentle urchin]

Check the input as the last thing before leaving the state ?

[frosty heron]

my trace was using notify state too, now I mixed it with baked data. Since Begin and End on Anim notify state is called I can always replay any traces that hasn't been done.

[gentle urchin]

Right so you somehow check the current anim frame and compare it to traces or smth

Impossible to do that with inputs tho

If an input is on and off between a single frame, the game will never know

[frosty heron]

Sounds like it

[dusky cape]

Hallo

[urban iris]

Hello, I'm currently performing a line trace to determine the mouse position in the world. It works well, but when I hover over the skybox, the trace location defaults to (0,0,0). This creates a visual glitch that I'd like to resolve. Ideally, I want to capture a valid position even when the mouse is over the skybox.
I've tried using the "Get Hit Results Under Cursor by Channel" node, but it didn't change the outcome. The skybox collision settings are included in the attachments.
Any suggestions on how to address this?

[steady cosmos]

Quite new to ue5 and I'm using interfaces to make a modular interaction system.
Everything has been going smoothly as all the interactables just have 1 thing to interact with (like a door handle), but not that I have way more stuff to interact with on a single component (like multiple buttons) I'm not sure how I can differentiate which button the player interacted with.
Would the best approach be to pass in the specific button that the player clicked as a parameter?
Tried googling some stuff, but I'm not quite familiar with the ue5 definitions and vocabulary yet so I didn't find anything useful.

(ended up doing it with the approach that I listed)

[gentle urchin]

Just return your own value if the mouse is outside bounds /unable to hit

Something reasonable. Last valid hit location, current pawns location or something

[urban iris]

I don't want it to be in a fixed position. It should update dynamically based on mouse movement

[gentle urchin]

Sounds like you should be using screen space location and not world space then

But if you really need to you can increase the trace distamce for GetHitUnderCursor by a stupid amount

Both the channel and distance are parameters of the controller

[mental trellis]

How do you not crosspost? (they deleted their post)

[frank olive]

(deleted it cuz I figured out how to do it)

[mental trellis]

Good! 🙂

[urban iris]

I created a sphere with inverted normals and applied an invisible material to it, so I actually made a fake skybox. It’s not perfect, but it seems to work. Thanks for your help!

[obtuse gale]

I have problems regarding collisions. In the prototype I'm working on the character has a hook, that can be dragged around and attach to objects. I'm trying to disable collisions between the hook and my player character, since it messes up foot positions, and surprisingly player controls (as shown in the video movement axis seem to change, for example when pressing W on keyboard chcracter doesn't go straight up, but instead goes in some random direction). I've disabled pawn collision on all hook actor components and experimented with "ignore actor when moving" but nothing seems to work for me so far

[autumn pulsar]

that's looking really good

are animnotifies reliable? was thinking I could use them to control when the damage gets output

[gentle urchin]

Yes*

[gentle urchin]

You gotta disable the ik trace channel that seem to be hitting it

Atleast thats my first thought

[autumn pulsar]

What's usually the best approach to making an animnotify call an event in the main blueprint?

[gentle urchin]

My current setup just calls an event in the owning pawn enabling weapon overlaps

Dunno if thats a solid long term approach

Probably not really

[autumn pulsar]

for now I was just going to spawn a hurt zone and apply damage to anything in that

[gentle urchin]

I wouldnt let the notify spawn anything but push event forward

[obtuse gale]

Sadly, I don't think that's the case, since problem appears even when i completely disable colision on character mesh

[gentle urchin]

"Attack" can mean one thing on 1 character sith 1 weapon, vs another with another weapon etc

[gentle urchin]

If you disable all collision on the hook, does it still happen?

[obtuse gale]

Then it falls trough the floor

[gentle urchin]

Uhh what

Affected by gravity?

[obtuse gale]

Yeah, it simulates physics

I want it to collide with pretty much everything except player character

[gentle urchin]

Not sure that will happen easily

With cmc and all

Personally id just define the behabiour as some "stop" or whatever

Anticlimatix

On the char you probably get a trigger OnHit or something

This looks far more intrusive than regular ik tho

[jagged thistle]

So. I just found out that GetInstanceTransform on a ISM component is bugged, and has always been bugged. It applies the parents scale wrongly.

Anyone worked around this before?

[raven fractal]

Hi everyone hope i'm posting this to the right channel, i am new to using Unreal Engine, I was trying to play an animation when i was pressing the attack button, it worked fine but it didn't go back and kept playing the idle state from my animation blueprint. I've took a look online and found out that if i used anim montages instead, it could've worked. Tried it, and now when i press the attack button, nothing happens. I've created a slot in anim blueprint and put it in between the state machine and the result, (same slot that my montage uses). Checked if they both are using the same mesh and skeleton, everything looks fine, but it just doesn't play the montage for some reason when i press the attack button. Thanks!

[old cypress]

Hey guys! How do I manipulate PhysicsAsset's specific physics body or shape during runtime?

[normal narwhal]

how to make if a object touch nothing he disapear

[olive yarrow]

I'm having issues having my ai follow a spline, it will usually fail or fail part way through.

My NavMesh is solid as everything else moves when not following splines and there's nothing obstructing the spline itself...

Is there a better way to go about making Galaga-esque attack patterns?

[gentle urchin]

Youd want to move towards an actor

Place a rabbit on the spline and move it ahead of the ai at the same speed

Or lerp it directly on the spline

[inland walrus]

Any idea why I cant reference the widget inside my HUD?

from my fpc

[lost hemlock]

Hi I followed a tutorial making this weapon wheel selection. I followed this tutotial exactly how I was supposed to...
and what this is supposed to do is wrap those buttons around the circle

But for some reason my buttons aren't wrapping around.

I feel like there should be some wrap box or smthing to wrap those things but there's nothing

https://youtu.be/ZJT2ij-LYzk?t=628

[olive yarrow]

would offsetting the other icons be acceptable in here?

[olive yarrow]

ooooohhhhh greyhound it... okay, i'll add a component to follow the spline and have the truck follow the component!

[lost hemlock]

I don't think so. I need to make this dynamically

[olive yarrow]

fair, i'm not great but i'm down to help brainstorm. Could we McGuyver a Throbber?

[gentle urchin]

Nothing does this circular. You can easily do the maths for placing them tho

[olive yarrow]

I'm actually at a loss, if i make a component follow the spline how will i have the ai follow it?

[gentle urchin]

Id make an actor (a pathfollowingTarget) that idnplace om the spline, and lerp forward on tick of the 'owning'(following) actor

[olive yarrow]

as so?

soirry that's an incomplete image

[gentle urchin]

Owner of ai pawn is ai controller

[olive yarrow]

heard thanks, as so?

[gentle urchin]

there's like 15 ways to do this

this is incorrect

[olive yarrow]

the methods never end

[gentle urchin]

Indeed

my suggested method is as follows:

• On Spline detected, Spawn SplineFollowingActor , put it some distance ahead on the spline, tell it which spline to follow
• Set AIMoveTo to the newly spawnd SplineFollowingActor

[olive yarrow]

this makes it go straight, that's an improvement

[gentle urchin]

ouf

the entire code there is incorrect

[olive yarrow]

somehow this seems to work?

[gentle urchin]

another method is; let the AI pawn lerp itself

the "destination" there makes no sense

nor does deltatime from event tick

GetWorldDeltaSEconds is a ndoe

[olive yarrow]

Checks out, i got that setup from some 360p youtube video

cancel that, doesn't work also goes straight. Which.. makes sense since it ain't right

[gentle urchin]

you're using BT's?

[olive yarrow]

Nah, i had used a blackboard for a moment to remember actor location in a seperate project though.

I know i'm just gonna be outta luck on the attempt - but i have been trying to keep the AI quiet simple (it's basically just a "modern 3d galaga")

[gentle urchin]

Ok so i got some examples laying around which might help you see whats going on

[olive yarrow]

Thank you Squize

[gentle urchin]

At the very simplest form, the following a spline track with lerp, really only consists of very few things;

• The spline
• The thing that follows the spline
• The logic of moving along a thing based on a speed

This is all the logic it takes to follow a spline, at a certain speed

Speed being the speed of the thing following the spline, Spline being.. thje spline, and the CurrentDistance is how we track where we're at (and where to move to, the next frame)

By modulating on the total length of the spline we ensure that we never go beyond the max length of the spline , and since this is circular, i can simply allow it to continue from start

[olive yarrow]

heard so i don't even need AI Moveto in this instance?

[gentle urchin]

Depends on your criteria really

do the AI do anything beside following the spline?

and/or shoot ?

[olive yarrow]

They shouldn't, it certainly isn't in planned in my Game Doc. They'll live a simple life. Spawn, Follow the same line as their forefathers, shoot a lil', and die.

[gentle urchin]

awesome

so is this some top down arcade shooter thing ?

[olive yarrow]

Yeah!! A basic ol' on the rails vertical shooter

[gentle urchin]

awesome

Tyrion 2000, here we come

Let's have this be a specific type of AI then

a SplineFollowing thing, for the moment

[olive yarrow]

my only concern when using delta time, world delta is that the frame rate my affect the actor using said time? unless that's not exactly how that works anyway

[gentle urchin]

(this could be latched in a component but that complicated things, for no use)

[gentle urchin]

world delta will differ from tick delta, if you have changed the tickrate

otherwise they'll be the same

[olive yarrow]

cool beans, i don't mess with any of the tick stuff.

Sorry, as you were saying?

[gentle urchin]

What I would do for something like this is Have a custom spline BP, which contains the spline track itself, and is responsible for spawning the things that follows the splines

New BP - reasonably named

[dark drum]

I'm using a spline track for player character movement in one of my projects.

Sometimes its nice to see different ways to do something. The spline is in a separate BP which is nice.

[gentle urchin]

Beginplay would be replaced by some outer caller, but that's for later

[gentle urchin]

modulo carries along the overshoot 🙂

Triggered and tick being updated per tick, means no interp is needed

any acc/dec would just be calculated manually

[dark drum]

Yea I've seen it a few times but forget when it comes to implementing it lol.

Scrolls up and replaces select floats

[dark drum]

Normally yes, but i don't use the movement component (or the floaty pawn movement one) so if I just had it run on triggered, it would stop moving the moment the player lets go of the input key.

[gentle urchin]

No because acc/dec would be on tick

triggered would only set the desired speed

current speed would be calculated in tick

both up , and down

braking might increase deacceleration, but it'd still be calculated in Tick, not Triggered

[olive yarrow]

Mm... Like collisions placed along the map?

I followed your set up and added a spline but the event tick logic you posted prior should be put into the TruckBP, right?

[gentle urchin]

yepp for excample

[gentle urchin]

yes!

[olive yarrow]

solid, i'll throw that sucker into the truck and see how that goes.
I also have an error on the Spawn Transform in the spline BP, should i just snag selfs world transform?

[gentle urchin]

I updated it a tiny bit

The truck class now got a SplineRef variable of the type Spline Component, and in my example a Speed variable (float) so that the same truck can have different speeds depending on the spline

i called the parent class "BP_MyTrackFollower" but feel free

[olive yarrow]

Heard o

i'll add that to the Truck - however i find myself unable to add a Spline Ref node to the Spawn Actor

[gentle urchin]

you must expose it from the class you're spawning

MyTrackFollower in my case

instance editable, and Expose on Spawn

after that, refresh the SpawnActor node, and it should show up

result

the logic in the pathfollower as it stands ;

[olive yarrow]

Good god you work fast, i'm still trying to get the SplineRef_BP to appear in the TruckFollower_BP 😂

[steady night]

got any ideas for taht ?

[gentle urchin]

make sure the class fed into SpawnActor is of the correct type, and not just "Actor" class

[olive yarrow]

I've them set as Charactrers currently

[gentle urchin]

yeah no

that doesnt work

it needs to be of the trackfollowing type

at the very least

to get the pins to show up

Another alternative is to pass in "self" as Owner

let me set that up real quick

[olive yarrow]

I'm sorry i'm getting lost now. Let me show where i'm at

[gentle urchin]

yankTruckClass cannot be Actor

[olive yarrow]

https://tenor.com/view/oh-yeah-its-all-coming-together-kronk-the-emperors-new-groove-gif-15921603

[olive yarrow]

Agh you just said that too

What exactly is a trackfollowing type? I tried to google it... heh...

[gentle urchin]

its the class you made

in your case, this

[olive yarrow]

Thank you for the patience Squize, that did create a slight change

[gentle urchin]

no no

almost

the variable should be a Class type

Class reference

they added this neat section at the bottom, FINALLY 😄

so swap to Class reference

[gentle urchin]

nice nice

[olive yarrow]

i... i'm sorry

[gritty wraith]

Is there a way to do "lambdas"? I need each button to work with a different value...

[gentle urchin]

Now SplineComponent object reference variable in the Farm_Splinefollow... class

mark it instance editable, Expose on spawn

[olive yarrow]

WHAM! (the variable is in components which isn't expanded atm)

[swift falcon]

They won't snap anymore

[gentle urchin]

Nice! Now swap SetWorldLocation with SetActorLocation

[swift falcon]

Send me a video of what is going on? I've used that setup with no overrides for multiple games and it gives nice clean intern for rotation changes

[frosty heron]

Pass in the value from the button?

Not sure about the context.

If you need some button to do another thing, you can do separate binding and separate event.

[olive yarrow]

went ahead and fully copied your post from earlier!

[steady night]

@swift falconhttps://gyazo.com/c27be7f1eaf2054259e8bda5acacdaf8

[frosty heron]

You want smooth rotation?

[gentle urchin]

noow share the results

[frosty heron]

I'm gonna be doing A.I soon . Pretty sure it's hard to get it to look right.

But imo just use rotation rate for aligning rotation to movement direction.

[gentle urchin]

same

[frosty heron]

Then for the montage, you can probably use anim notify state to interp the rotation to the target

[gentle urchin]

and stop interping for a while

[gentle urchin]

If you wanna use the overlap, the overlap logic should also do the beginplay stuff

setting the lifespan

then just remove beginplay altogether

unsure what the overlap triggers from tho

this would probably exist in the splinebp , not here

probably 🤔

[untold niche]

In the character movement component tick off Orient Rotation To Movement and Tick on Use Desired Rotation
The lower the Z Value the slower the actor will turn

[maiden wadi]

I need to stop procrastinating and write my weather/time of day system.... Aaaand that's my cue to go play Traveller's Rest.

[gentle urchin]

I should leave this discord so i can actually get some work done

..maybe

[olive yarrow]

I think i went wrong here

[gentle urchin]

Im undecidied on the dungeon generator still

[maiden wadi]

I tried that once. I just play more games.

[untold niche]

I mostly lurk in here so I can learn from other people problems while I work on my project lol

[olive yarrow]

but the overlap was intented to trigger the spline/actor spawning - though i spose it's not exactly necessary

[gentle urchin]

I would think the overlap should start the spawner

not tell the spawned things to move

[olive yarrow]

yeah!

[untold niche]

I've learned a lot of stuff from watching people troubleshoot other peoples issues before they became my issues

[autumn pulsar]

It's not a bad idea

[gentle urchin]

so it should exist in the BP_Spline

[olive yarrow]

oh wait yeah

[gentle urchin]

and not in the truck itself

[frosty heron]

Do you have trello? It's been helping me greatly

[gentle urchin]

truckitself just spawns and is s ent on its way down the hill

[autumn pulsar]

Anyone happen to know of a good guide to setting up a basic combo system for melee weapons?

[gentle urchin]

Trello doesnt keep me focused

in fact, it steals more focus

[frosty heron]

The checklist take a load off

[gentle urchin]

just do the work, instead of planning around it

i got checklists

but they're broad strokes mostly

[maiden wadi]

With Squize there. I would need multiple personality disorder to make planning apps work.

[frosty heron]

It's not about the planning for me but the checklist.

Instead trying to tackle a giant work in a day, I can sleep easy knowing I've done the baby steps

[olive yarrow]

gotchya, the otrigger overlap in SplineBP causes Event BeginPlay?

[autumn pulsar]

checklists make sense for long term projects

[maiden wadi]

Like I love it when someone else write a checklist... But when I write a checklist, I just start spiraling into... Does this need to go on the checklist? Like how specific do I need to get... Cause I can do this and then.. yeah but.. Hmm.

[gentle urchin]

The trigger replaces "Beginplay" in SplineBP, yes

[frosty heron]

Pretty sure most of us here stuck will be stuck for years with our project

[gentle urchin]

haha tell me abouit it

[stable birch]

stuck on the same check too

[gentle urchin]

so i keep them stupidly broad

[autumn pulsar]

I hope to finish this project or at least get most of the way there in a year lol

[stable birch]

“3-5 years later”

[autumn pulsar]

but it turns out game dev is actually harder than I thought to no one's surprise

[gentle urchin]

7 years down, 0 games out

persisting with a project you grow tired of is the hard part

[autumn pulsar]

Well A, I'm keeping the scope somewhat sane, at least in the art department

[olive yarrow]

leeeeeemme repost my blueprints

[autumn pulsar]

and I'm trying to make a vertical slice rather than a full game

[gentle urchin]

been there tried that

[spark steppe]

i guess the most "progress" is made while starting a project

fleshing it out is where the pain and work starts

[gentle urchin]

It's a bit weird isnt it ?

one would think seeing the pieces come together would feel great

[autumn pulsar]

last 10% is 90% of the work

[gentle urchin]

but its like building a house

constructionwork is the fun part

getting the frame up shows tons of progress

feels great

[olive yarrow]

i feel an odd malease sometimes when finishing a segment, then i kinda slow down progress....

[gentle urchin]

then the 18 different less exciting disiplines comes in..

electrician? Worked for 15 weeks, cant see a damn thing

[autumn pulsar]

I've finished a few projects, and that last bit is rough, but extremely satisfying

[frosty heron]

Planning is easy, execution hard.

It's like pushing a boulder. That's why I break the task down so I can work on smaller task that I think I can do that day.

And the law of inertia kicked in, I end up doing more work than my daily mini goal.

[autumn pulsar]

currently in the learning honeymoon phase

I'll likely need to refactor everything when I try to add saving and loading

[gentle urchin]

thread it

[olive yarrow]

I'm gonna be missing something dumb aren't I ?

[autumn pulsar]

and level streaming

[steady night]

i have thse setting he stilll snapps

[stable birch]

“Yay! I finished my first enemy, now I just need a whole games worth of enemies with varying gameplay mechanics”

[autumn pulsar]

Vertical slice is easier since you don't have to worry about metaprogression

I'm planning maybe an hour of gameplay

[stable birch]

That’s still years most likely unless you’re completely forgoing art

[gentle urchin]

Atleast we're not making MMO's.... .right?!

[autumn pulsar]

well I'm doing gamecube art so pretty close

[stable birch]

I would expect this to take multiple years still~~

[autumn pulsar]

possibly

we'll see where I'm at in a year

[stable birch]

I’m saying this from experience hahah (you end up redoing a lot of work as you learn the proper ways to do things)

[gritty wraith]

I have n buttons and i need button 1 to use index 1, button 2 to use index 2...

Each button displays different text on the right side

[autumn pulsar]

yeah kind of going in with that mindset

I have about a year's worth of experience with C++

[steady night]

got it working

[gentle urchin]

I'd suggest creating widgets for those

not "Construct Text" and not "Construct button"

but actually "Create Widget"

[autumn pulsar]

and as for art, I have 10 years experience, so I can get animations, characters, and environments done pretty fast

[gentle urchin]

Pass in whatever data you need the button to know about

[gentle urchin]

I envy that

I got 10 years of programming, 0 in art

i can get shit to work, but i cant make em look like anything

xD

[autumn pulsar]

never too late to start

I eny the opposite

[gentle urchin]

my artistic talent stayed absent my entire life, doubt it's gonna show up now

[frosty heron]

Store the index in the button. For the broadcast delegate you want to pass the index.

Then on the event.

You can do a switch case.
To respond to diff index differently ( one way of doing it )

[gentle urchin]

I'll stick with what i feel like i know, and leave the rest to others

[autumn pulsar]

I think anyone can learn anything

[gentle urchin]

I agree

[autumn pulsar]

just a matter of putting in the time

for me I'll just commission music and animations

[gentle urchin]

There's simply not enough time^^

[frosty heron]

I just want to do game dev full time.

[gentle urchin]

same

[frosty heron]

😔

One day perhaps

[autumn pulsar]

I'd like to but I don't want to join a studio

[gentle urchin]

full time work+ kids,

whatever remains after wife takes her cut is left for gamedev

[autumn pulsar]

maybe I can make a slice of life then get a patreon and see if I can make the full thing

[copper chasm]

I have 97 days until my daughter arrives, I have ASSURED my wife I'll have a vertical slice ready by then

[gentle urchin]

Gogogo!

[copper chasm]

I'm expecting i'll just take a fireman's axe to my PC

vertically

[untold niche]

Nice!

[gentle urchin]

And congrats 🎊

[copper chasm]

I think my favorite part was swapping to C++ base classes for everything in the 11th hour

but hey, i got my giant grid

[gentle urchin]

Haha tell me about it lol

late changes

"let me just create more work for myself, so i dont have to make actual progress" 😄

[gentle urchin]

im sure if i just worked on the game instead of being here, one title would atleast be out by now.... maybe

[copper chasm]

Hey, your coffee fund is pretty much set to start pulling dividends at this point, you are appreciated here

[frosty heron]

I am guilty too but without you and other amazing people here. I wouldn't be able to solve some of the critical problem.

Deleting discord help temporarily. Usually I rejoin once the check list is ticked.

Or when at work

[gentle urchin]

I'm leaning towards more work for the procedural levels.... arhg, not really what i need xD

But i doubt ill be satisfied with DA results

[frosty heron]

Not sure if I want to use WFC anymore

[gentle urchin]

You used it ?

[frosty heron]

But I'm gonna make sure to put dungeon generator last

Nah, can't even workout the math yet. I am a drop out.

Once abilities, A.I, inventory, and equipment done. I will tackle it

[vague moth]

not sure where to post this,
but could someone help me with memory management?
I know about hard and soft references and such, and how any asset which is hard referenced within in an actor BP is also loaded into memory.
My issue comes with the odd delay on things like audio and particle effects (specifically shaders compiling)
which still happens despite my player character being loaded in.
Can I somehow run a check that the player only spawns when all the associated assets are actually loaded in, or is there something else I'm missing, I would appreciate any help

[gentle urchin]

thats what i should focus too, tbh

but it was while doing the pickups that i realized how little control i have of the dungeon

[frosty heron]

I don't think checking those is easy work, even lyra spawn their character early on with things still being streamed.

[frosty heron]

Shader compiling only in editor anyway. You won't have to worry about it on shipping.

[spark steppe]

does anyone know why the BP Macro Manipulate Float Internal is so weird?

[frosty heron]

Lyra loading screen adds hard coded minimum delay just to wait for things to be streamed in.

[spark steppe]

i don't get why they set the value to a local variable

[stable birch]

AAAA

[vague moth]

I'm not sure on that
I tried to launch my game as a standalone, and the shader compilation was still there

[gentle urchin]

that's some weird logic

safe copy thing ?

[frosty heron]

Stand alone doesn't represent shipping.

Package your game and it's fine.

[vague moth]

Like I'm not sure if I'm missing some sort of check from the engine, to see if the asset is completely loaded in

[vague moth]

I'll try
but It's gonna take a minute🫠

[frosty heron]

I got those shader compiling thing as well, but it's only gonna happend in editor.

[vague moth]

But thats weird
what is standlone game simulation then used for?

Either way
thanks for your help, I'll let the game get packaged and hope that the weird delays and such are gone then

[dawn gazelle]

It's for testing the game as if it is single player, but it just doesn't behave exactly as it would when the game is packaged for shipping. Running in the editor allows for quick testing and iteration.

[crystal ridge]

Hard question folks, how do you change the value of a hash table/ dictionary in blue prints?

[sick sky]

you cant

[crystal ridge]

I'm seeing a few example for getting but none for setting.

[crystal ridge]

Really, then why am I allowed to create this set node? Anyways, what can I do? I need a hash table.

[sick sky]

could you explain what you want better ?

either i didnt understand because im tired or because you arent using the correct terminology

to change a value in a Map in BP you use the Add node

since Add will replace the key:value if it already exists

[crystal ridge]

I need to create and manipulate the values in a variables's map

[sick sky]

use Add

[crystal ridge]

Does "add" like overwrite existing keys and create news one if they don't exist? That would be perfect btw.

[gritty wraith]

How do i put new line characters here???

It displays them as \n anyway!

[mental trellis]

Try shift+enter instead of \n

Also you need to add the MultiLine meta tag to the property I believe.

[gritty wraith]

ooooh

[crystal ridge]

Thanks bro or whatever..

[dawn gazelle]

Yes.

[sick sky]

yes

[unborn maple]

Any idea why my AI Perception doesn't see the tag even tho it detect it on the first go and see the tag

once it get to get actor perception it showing as none

which is weird since everything is in the same blueprint

the other half is just promoting the array in to a variable

i made sure the actor tag was set on my player character and that i had ai stimulus as well.

[final python]

I feel like they should add an editor preference or something that lets you turn on advanced blueprints, and you get access to more (seemingly; for epic) easy to implement c++ features. Stuff like allowing unsigned values and stuff like that. Basically native c++ things that blueprints doesn't incorporate just for user simplicity.

[grave relic]

Hey, so I apperently goofed and need some help. I added a variable to a struct and it broke everything. Ive gone through and refreshed every node that has something related to the node. Deleted intermediate and save, regenerated files but no luck. Tested to add new values, remove, save and load in different orders, restarting project etc. But no luck, please help :C

[spark steppe]

the only kind of reliable way to alter BP structs is to save everything, edit the struct and save it, then close the editor without saving anything else

everything else is russian roulette with 5 bullets in a 6 bullets revolver

[frosty heron]

And a misstep will cause silent error

[copper chasm]

the impetus for my learning cpp

[desert glade]

true

[frosty heron]

There's no 100% real safe zone. Recently I broke my bp just from adding and removing component in cpp.

[desert glade]

But I've found that updating the redirector can prevent this from happening

[frosty heron]

Had to do the entire bp again.

[desert glade]

Do you need to manually destroy the level suquence Actor?

I found it doesn't destruct when it's finished playing

[grave relic]

Yeah did try this as I saw it in a thread, but did not fix it 😭

[prisma jay]

Could someone help me look over my blueprint for highlighting objects I've declared as interactables?

[spark steppe]

if stuff is already broken it won't change a thing

it's broken now....

use a backup or fix it

[grave relic]

Yeah feared that would be the case. Thing is I don’t know how to fix it. Besides making a whole new struct. But that might be the fix then

[prisma jay]

The intended design: when I press "F", I'd like to enter into a 'thought mode'.
While in this, the cursor aligns to center of screenpos.
From this, I can hover in the screenspace over objects. If it is an object that is a "Interactable" (certain objs have parent of "interatacble"), then I'd like for it to be highlighted.

The object parent has a "Enable Highlight" and a "Disable Highlight" options.

When I hover over an interactable object, it should- highlight that object.
When I stop hovering over that object, it should - stop highlighting.
If I move from one object to another object, it should disable highlighting and then re-enable on the object I'm currently hovering over.

That way if you go from one object to another in one motion without going to a "non-interactable" object, it'll always just be the one object being highlighted.

[desert glade]

I have a requirement: After entering an area, the player goes to a location and plays a Level Sequence.
Whether the ability to walk to a location should be implemented in the Level Sequence.

[frosty heron]

You can fire an event in the level sequence that trigger the walk

But that won't be frame dependent or reliable

[desert glade]

Yes, that's what I'm going to do now

[frosty heron]

I would just manually animate the root and play the walk anim in the level sequence.

That way what ever rendered is always consistent

If I use simple move to or w.e path finding you choose, what if something blocking the way?

It do make a weird cinematic.

[desert glade]

But I'm making 2d games

[frosty heron]

Unity would be a better option for 2d imo.

2d support from epic is kinda non existence.

[desert glade]

unity doesn't have its own behavior tree and many handy features.

[frosty heron]

Only touched it for a bit but the 2d support at least existed.

You can draw custom collisions too there.

But yea your call ofc.

Just saying majority of people would probably use other engine for 2d

[prisma jay]

Any ideas on this?

[desert glade]

unity's cinemachine and sprite shape are handy features that I had to deal with in unreal.

[pulsar osprey]

yeah id definitely use unity or godot for 2d

godot honestly feels as good as unity for 2d in my experience

and it's free, so

[maiden wadi]

Lost the details panel?

[maiden wadi]

What is the issue you're having?

[prisma jay]

I can enable the "thought mode", and cursor moves to center of screen, and then i can go and hover over an interactable, but then it doesn't properly trigger the highlight enable

https://blueprintue.com/blueprint/8v06st1l/

here's a blueprint ue for viewing

ill post a gif, give me a second

[maiden wadi]

Disconnected execution lines don't run.

You've never actually set HitActor.

[prisma jay]

wait what

where

[prisma jay]

Aha.

https://tenor.com/view/picard-facepalm-oh-no-oh-hell-no-no-gif-10723914200679373178

Another issue I think

@maiden wadi Thank you for the help above. For this, I am trying to figure out if this is the right logic here.

Maybe a better way to do this?

Basically while hovered over it, the actor should be the "current" highlighted object.

But I just do this by calling the enable highlight to that object in the blueprint above.

but i never seem to get to that. It just constantly disables the old highlights of the "Last hit actor" / LHA

[frosty heron]

Missing component on spawned actor.

It's there in the template

Keep getting null ptr... ejected from the controller and find out its missing.

Re create the bp from scratch, works

[zealous moth]

@frosty heron This also happened to me. Sometimes the character mesh skeletal mesh component becomes null in cpp. No idea why. Have to recreate it.

[violet bison]

which one is better for a turret?
when not having a target, have a time function that runs 0.5 second that detect if anything is within its range
or having start/end overlap events

[zealous moth]

@violet bison do you want it to instantly detect stuff or not? If yes, overlap. If not, timer.
Personally I would go for overlap as it does not consume ticks needlessly.

[violet bison]

ok, if it doesn't hurt performance I might go for overlap

[frosty heron]

Bp is binary asset. Hot reload is the usual suspect but it can break any time for no reason. And corruption is terminal I heard.
Source control can help but sometimes you don't know at what point it breaks.

[zealous moth]

I just recreate from scratch. Least headache

Most of my stuff is broken into separate classes

[frosty heron]

Yeah, so now I try to keep is bp very minimum for my character bp

[gentle urchin]

Use Authaers fixer

[zealous moth]

Less work long run

His what now?

[gentle urchin]

Corrupt bp fixer

[frosty heron]

Duroxigar and authaer have fixer but I don't think it's a cure for all cancer.

[gentle urchin]

Nah

[zealous moth]

I don't fix that way. Hands on or nothing.

[gentle urchin]

Its cure for 1 specidic cancer

[frosty heron]

Prob try theirs before re creating

[gentle urchin]

Depends on work but yeaj

[frosty heron]

If it's just empty detail panel, I will use their plugin.

@gentle urchin is the daily task complete?

🐈

[zealous moth]

Install fix; suddenly gpu fans blow up and thisIsNotAMining.exe is using it

[gentle urchin]

Yes, i just checked off "sleeping"

Actually i didnt , going back to sleep now 🤣

What I will do is agree to postpome

The dungeon generator problem

And instead just complete the pickup/inventory regardless

[autumn pulsar]

Is there a way to for loop through a data table and return all the structs in it?

or access by index at least

[frosty heron]

Afaik you can get the rows

And you just loop through the row -> get data table row

You don't need to access by index and no

DT is a Map internally

Index doesn't mean much here , you get the value by the key (in this case, the key is the row name)

Technically you can get the index of the returned row but what use case require you to do that. A re arrangement of the DT and your logic may break.

[autumn pulsar]

hmm, trying to figure out the best way to do a combo chain

then adding branching as well

for if you do the ""heavy"" attack

I could do a linked list I suppose

but need a way to author that

Is it possible to pass a variable to a function?

like I want it to set the variable that gets passed to the function rather than returning it then setting it

ah there's pass by reference

[trim matrix]

If anyone wouldn't mind, could anyone break down what's happening where I marked with red. PlayerIndex I know it gets the current Player. After that it's blowing me up.

[zealous moth]

do what coldsummer said. I use this.
As long as you have less than 1k rows, it will be fine in terms of performance. You can also set soft refs and only load and cache what you need

[zealous moth]

you get the player index ref to know which player. it's typically the first.
You then get a trace hit from the cursor onto the first object it hits through that collision channel of visibility.
You then break the hit struct and get the location.
Then, you use the actor this is in, dunno what this actor is but it wants to face that location.
You then get the rotation you need to make that actor and that location face each other and use that value (angular) to set the new rotation

[trim matrix]

That's what I don't get, this trace hit part and this break. What is exactly breaking

[zealous moth]

when you trace, you send a beam from location X to location Y and if at any point it intercepts something, it's registered as a "hit".
The hit can be broken into a location, a distance, an actor, a compoenent, whatever.
You just need the location.

[autumn pulsar]

so a "hit" is actually a collection of various data points

such as the the object you hit, where you hit it, the surface normal, etc

so "breaking" a hit is basically just saying "I only want this part of the hit"

[trim matrix]

So he just wants the Location of whatever his mouse hit

To make the something rotate towards there?

[zealous moth]

yes

[frosty heron]

Hard ref in DT is wild

[gentle urchin]

I like living on the edge ^

Ensuring toasters cant runnit

[frosty heron]

UE5coro made my life easy

[frosty heron]

My combo for combat is just evaluating processed inputs

I will have array of combos which are associated with an ability

E.g light attack, light attack, heavy attack -> do special moves

Light attack , dodge, light attack -> do jump attack

If no combo is found, just process what ever the input is associated with
E.g left click for light attack

@gentle urchin some things you just can't live without after trying.

Like source control

Anytime I messed up when setting up physich asset.

Just right click and revert.

Time travel saves me plenty of times

[gentle urchin]

Does it handle bp changes?

[frosty heron]

Yeah but can't have multiple people working on it.

It's binary file

Still got that nice revert.

Anytime you want to "save" your work. You just take a snapshot / commit.

Good when prototyping. Anytime I need to clean up test codes didn't work, just right click and discard changes.

Then bp is back to where it is last commited

[gentle urchin]

I suck with commit comments 🤣

Always lazy about them

[dawn gazelle]

• Fixed the thing

[gentle urchin]

Indeeed !

😂

I tell myself the specificity lives in the commits so.... no use doing it twice

[odd veldt]

Can someone confirm this UE5.4 bug, or did I miss something.
I have a simple pawn with floating pawn movement, but If I set the camera to orthographic the camera always moves with the pawn and ignored the parent location. (If I set the camera to perspective it also works, but I need the orthographic projection!)
**I have this problem in my actual 5.4 project. **
tried the same in a 5.3 and it looks like its working there. (...and I dont want to download 5.5 just for trying this)

[maiden wadi]

I think I'm too tired, but I'm not sure if I'm following correctly. if you set the Arrow component to World movement so that it isn't attached to it's parent, and set the camera to ortho, the camera still follows the capsule?

[odd veldt]

pawn does not have a capsule, but yes, the camera still follows the pawn movement and does not stay on thr arrows location

[maiden wadi]

That's... Odd. I can test in 5.5.1 at least.

[odd veldt]

The problem occurs only with camera set to orthographic, perspective runs fine.
but I need a exact orthographic projection to avoid "pixel errors".

[odd veldt]

thanks, maybe I download 5.5 if its working there, its easier to upgrade the project than starting with 5.3 from from zero.

[maiden wadi]

Uncheck AutoCalculateOrthoPlanes

I'm unsure what that is doing, but unchecking that causes the camera to stop following the pawn. But yeah same thing in 5.5.

I should check out Ortho stuff again now that it's getting some attention.

[odd veldt]

I'm sure I tried this and id did not help, funny 5.3 does not have this option.
I'm at the office now and cant try it, I give it a look later if I'm home again. thanks for trying! ❤️

[gritty wraith]

How can i attatch an actor to another actor? I want player to move to this location infront of the monster so that the player is staring at it for a bit before a death screen.

[gentle urchin]

You dont need attachment for that

Just provide that exact vector for the player to move to

[random vine]

so each time I save the level, it shows that it needs to be saved again.

[stuck palm]

Hi, any idea why Add Controller Yaw Input is not working? I' m following a simple tutorial, but it doesn't seem to affect my Pawn in any way. I can see it in the debug logs that it's being called.

[dark drum]

As a guess, the pawn isn't set to use the controller yaw. (set in the default settings)

[dapper fern]

I found this project on Github that I downloaded and the repo/explorer confirms that there's supposed to be BP and other uasset files but I see none in the Editor. Google tells me it's corrupted and pretty much undoable. Is it true ?

[still abyss]

how can i made a lipsync from the soundwave or viseme data?

[empty hare]

Hi guys, i made a weapon blueprint but whenever i step on it, it either launches around at a million miles per hour or glitches through the floor.
Is there a way i can stop it doing this without removing the entire collision between the gun on the floor and the collision capsule?

[main lake]

why do you need the collision on your weapon ?

[stuck palm]

Thanks, it wasn' t set. But now it is and still nothing happens. 😦

This is how the object is set up by the way.

[frosty heron]

What is the bp derived from?

[lost hemlock]

Why is this one so laggy?

This is only temporary code ( I wont keep this forever, its just for debugging)

idk why the OBS is so laggy, but anyway.

This is the code

[stuck palm]

My own c++ class that extends Pawn

[empty hare]

so it doesnt fall through the floor

[main lake]

If it falls that means you enabled gravity for it, do you need that gravity ?

[empty hare]

yes

so its an object

i can pick up

and drop

[main lake]

Set your collision preset of your mesh in your weapon BP to this

And physics to this

[empty hare]

i dont have any option for mass

this it?

[main lake]

are you sure you're selecting your mesh and not something else ?

[empty hare]

Would it be easier to set it up so when i drop a gun it snaps to the ground?

[normal raft]

is there a advantage to doing this? whats the difference ?

and is that the corect way to do it?

does it mean it can virtually modify the graph of the material at runtime ?

or is it also for doing scalar params after construction events like beginplay

[normal raft]

one thing that i found really helped me out with the mass stuff is to use physics materials then you can define the mass and a bunch of other properties more reliably

its a bit more work but worth imo

the physics material also lets you set values like friction and such

and yeh more fun to have meshs that have "physics materials" really they should of been called Physics Properties Collection or something .. but yeah what ever atleast with that a bolder weighs 1000kg and it means it 😄

[polar siren]

Hello, anyone got experience with **NetDB **plugin for PostgreSQL? Got a problem that "Prepared Query" block dont work while classic "Execute Query" block works. More info at screen.

I've got this in UE server log:
LogNetDB: Warning: You passed an invalid prepared query into the Execute Prepared Query node! Please double-check your query's syntax, and ensure you have all of the properties connected up.

And this in pgAdmin:
could not receive data from client: unrecognized winsock error 10054 (not sure if related)

I would expect network issue, but since Execute Query block works without any problem, it seems that problem lies else where than network. I've got through their documentation https://docs.h2cstudios.com/netdb/troubleshooting/prepared_query here, but no luck.

Any help appreciated.

NetDB plugin version 1.0.14
UE 5.4

[normal raft]

did you check the was sucessfully boolean before proceeding to prepare query?.. oh nm i see now you did

[empty hare]

is a physics material hard to set up?

[normal raft]

not hard at all

just right click create physics material.. name it.. configure it .. and then assign it to what ever accepts it 😄

[polar siren]

yeah, the connection is set and active, execute query works, but prepared one doesnt, it should have protection against SQL injection so I would like to use that instead through my project.

Can't figure out why it doesn't work tho.

[normal raft]

yeah maybe the security level is preventing that particular syntax

[empty hare]

Appreciate it!

[polar siren]

well its official syntax from documentation...

frustrating

[normal raft]

unless its being mangled client side its hard to tell can you watch the query live on the sql server?

or what ever db server its running

if its a hosted solution you might be able to craw your db logs

and see if the db didnt like the query

like via the cpanel or something

[polar siren]

I'm hosting it, all I can see is

[normal raft]

I believe that is connection reset by peer

[polar siren]

well, why? 😄 I can't see what exactly is being triggered which may help. Or don't know how to identify it

[normal raft]

well you know who hung up on who

did you try it with out the semi collon at the end of the syntax just incase unreal doesnt like that for what ever reasons

[polar siren]

yeah, same error.

[normal raft]

any thing in the main log?

for unreal?

[polar siren]

that DB connection is alive and

[2024.12.30-15.46.17:704][ 57]LogNetDB: Warning: You passed an invalid prepared query into the Execute Prepared Query node! Please double-check your query's syntax, and ensure you have all of the properties connected up.

when trying to run query. The syntax is 1:1 to documentation, just for sake if I do something wrong. Maybe its something in PG, but no clue what, since I'm not sure what the plugin is actually trying to do with the Prepared Query.

maybe the plugin is bad, but it is well rated, so I'm the problem probably 😅

@woeful halo is the owner of the plugin, maybe he would know

[frank olive]

How can I set the max speed from tying into the SET "Orient movement to rotation", what I've tried hasn't worked

[normal raft]

try clamping it or something

[normal raft]

is the a node for prepare query

no

what i mean is there a node to create query

or make query a local variable first or something along those lines

[polar siren]

and this, which is used in the plugin to translate input in ^ block I think

[normal raft]

ah wait what options are there for Format?

i wonder if thats a enum for different DB types or some such

[polar siren]

it expects string

[normal raft]

oh right

but my var isnt connected?

[polar siren]

yeah, I just set it to screen. It doesn't work in any way I've tried.

with or without variable, just plain SQL, nothing. Dunno, maybe there is some internal issue, even it is kinda weird I would be the only one dealing with this.

[normal raft]

yeah i kind of think it is seeing as unreal thinks the problem is on its end

[polar siren]

But I think the plugin side is at fault, since no query gets to the PG, it breaks before that. I would suggest some failture mechanism to prevent any wrong SQL queries, but why, who the hell knows.

[normal raft]

and also complains about your request in correctly .. also while not being supplied a db type unless that settings lurking some where some how

how would it know what netdb your talking to ?

something remotely compatible with sql

[polar siren]

Well It opens the connection but breaks before any execution being made, dunno.

The Execute Prepared Query fails, halting the process, saying I'm using wrong syntax, even if I do the example one from documentation.

[normal raft]

yeah i know theres stuff out there that needs to be specified a remote db profile interms of any api

litterlally like php would slap in a .ini file or something

[olive yarrow]

How would I go about making my Spline actors still respond to the landscape mesh?
I can see why they wouldn't cause like.,... spline following. But yeah, how would i... do that

[normal raft]

if there just actor you oreientate them to the world origin and what not

if its a unknown world etc just use or spawn a arrow to show up at least

literally i would recommend also using the planet grid thing if your games a planet grid thing to then forcefully plop the player onto the surface using a single line trace

[olive yarrow]

Thanks for helping! Inside These nodes?
also is it NC ore dump or N Core Dump?

[normal raft]

No Core DUmps 😄

[olive yarrow]

Solid, no idea why i was curious but i couldn't let it go unanswered

[normal raft]

no one usually asks ;D

[olive yarrow]

Well, i care ❤️

[normal raft]

they just think its some agressive name

[olive yarrow]

honestly, does sound like a basement grunge thing

i'd go see'm, prolly in pittsburgh or whatever

[normal raft]

yeah when we first got into computer we had to deal with day to day core dumps and learn how to fix them etc

[olive yarrow]

I had to google core dump to make sure it was similar to other dump stuff. I'm out here learnin' today sheeeeiiiiitttt

[faint creek]

Hi guys, is it possible to set "can ever affect navigation" in Blueprint?

[violet bison]

is there a way to rotate a bone to a world rotation?
