blueprint

[faint pasture]

Bruh you need some instanced meshes maybe

or just let nanite save you

[daring vapor]

I see why I was having trouble find that, I can't use the spawn actor of class in the construction script. Gonna keep looking....

[gentle urchin]

Not mine, but im all for the instanced meshes!

[gentle urchin]

You can

If you really want to

Just toss it in a function

and call the function from construction script

(unless they fixed that)

you can also make editor functions

callable from editor

there's some "gotchas" with that method tho

like moving the owning actor would make it clear its array of references

[median orchid]

Is anyone able to help? I'm trying to make a ricochet effect using physics based bullets. But everything I do it does this

[flat coral]

Reupping, is there any way to search a level for actors with a specific component? Or even just get the components directly?

Like, in BP at runtime

[daring vapor]

Hmm, interesting. I'll see what I can come up with. Thanx. 🙂

[tight schooner]

If you don't find a straightforward way, I can think of a more convoluted way... If it's a custom component, have it add an actor tag to the host actor. Then you can get all actors with tag.

Or if not, have the parent actor class do that on construction

[flat coral]

Hmm now I gotta weigh this against the hack I was thinking of... which is to have every component of this class (it is custom) add themselves to a list in my GameMode or something on BeginPlay, and then just call to get the list.

Which is probably more efficient now that I think about it, no traces or overlap tests

[gentle urchin]

Is it a hack to store it in a manager

I wouldnt say so atleast :p

[flat coral]

This FEELS a little hacky to me lol

[gentle urchin]

Usable components ?

Is this like an interactable?

[flat coral]

yeah it's a custom component that makes any object interactable and exposes an "OnUsed" event. Also handles things like on-focus prompts and highlights.

[gentle urchin]

And you dont want overlap?

[flat coral]

Overlap?

[gentle urchin]

To register nearby interactables

[flat coral]

Well like I said the problem is any object can be interactable, if it has this component.

So I can't look for objects by class or whatever

[gentle urchin]

No but this component

Can add a collision component to the owning actor

Which it uses to register to the player?

If thats not usable then your method seem fine^^

[flat coral]

Maybe but that seems like more of a hack than what I'm doing. Probably more expensive too this just iterating a short list once

[gentle urchin]

Anything at that point is a hack , is it not

[flat coral]

Yeah, but some things are more hacks than others 😛

[gentle urchin]

my interaction component does exactly what i suggested 😛

Was rather pleased with it, but now that you've made me aware that it feels hacky.. . perhaps it does feel hacky

[flat coral]

Also the trick is I'm doing this on tick so efficiency matters a lot. What I'm working on right now is a sorta "scanner pulse" that highlights objects in an expanding sphere

[gentle urchin]

Ah

well iteration of a list might be better

[flat coral]

I also kinda don't like the pattern of modifying the parent actor, if I can help it. These can be put on ANYTHING, even like static mesh actors in level.

[gentle urchin]

That's a fair point

It's usually not a desired pattern

[zealous moth]

sorry i was reading and got lost, what is it that you want to do?

[flat coral]

Dont worry, I'm good here 🙂

[zealous moth]

@flat coral well... did using the dot product help?

[zealous moth]

You need to change the projectile motion to increase bounciness

[flat coral]

Well... not directly, but the "get distance between two vector locations" function MIGHT be using the dot product behind the scenes?

[gentle urchin]

If theres many objects, you might benefit from using squared distance ^^

Or generally c++ and then squared :p

[flat coral]

I dunno, when I start optimizing this project, I think I've got way lower fruit than this

Shit like "I don't know what level streaming is, and at this point, I'm too afraid to ask"

[median orchid]

I'll give it a go

[median orchid]

And what do you mean by projectile motion?

[zealous moth]

how do you shoot?

[median orchid]

I get the tank shoot arrow and use projectilemovement

[gentle urchin]

Let me know when you ask, so i can spy on the answers

[cloud citrus]

i have a static mesh in a blueprint actor pawn and it is not in the middle

where it is right now is the place I want it to be in the game but when they overlap with the coin it doesnt trigger an event

(print string)

[mossy perch]

Assign a hitbox to the coin
Also does it trigger at all?

[cloud citrus]

no

to test it, I put a print string and it doesnt trigger

[mossy perch]

Show me the bp

[cloud citrus]

how

[zealous moth]

what is the collision preset?

of the actor as a whole and the coin?

[vast horizon]

Can anyone shed some light as to why Call To Parent Function is not available for this event?
This is a child class of another blueprint, its a health pickup child of general pickups. I just need this one to check the player's health before continuing with the rest of the pickup functionality, but I can't seem to return the blueprints flow to the parent class functions

[gentle urchin]

Its a delegate

[daring vapor]

@gentle urchin Got the dominos working. Thanx for the help. 🙂

[gentle urchin]

Well done ! Did you take a big hit in performance i wonder

[signal hornet]

Hey guys, I'm having issues replicating a mesh's movement, I've ticked the 'Replicate Movement' tick box in the meshes settings but still isn't syncing for all players? Could it possibly be because I have placed it in the level as apposed to having it spawn in after a set number of seconds (via say a gamemode bp). Any ideas?

[fierce birch]

is it possible to add a row to a datatable from a text box?

[gentle urchin]

No

Datatables are static

[fierce birch]

ok thankyou

[mossy perch]

UE5.0.2
Trying to setup EOS but always fails on Create Advanced Session
It pops up the web browser to log me in, but then it fails.

[fierce birch]

if i wanted to make a var that doesnt get deleted when i close the editor where would the best place be

[mossy perch]

in the cache

[fierce birch]

im assuming ill have to use a save game obj

[daring vapor]

Nope. All good so far.

[bleak swift]

Still haven't found a solution to this. The character seems to do this when you hold down W or S and then instantly release that key and press A or D

Here is my Code

[rain egret]

i wonder, why can i create a child of a static mesh component but not of a procedural mesh component

[torpid hound]

Probably because creating a child of primitive component implies you need to implement rendering and/or collision which is not really a blueprint thing

[rain egret]

hmm, so time to think around corners

[cedar sparrow]

is there an enum variable type that is just Horizontal/Vertical or do I have to make my own?

[faint pasture]

Boolean or just make your own

[faint pasture]

Why are you doing all this, this is gross.
You already are handling the input elsewhere

Convert from your velocity to a direction (int or enum)

then select a flipbook based on that

If velocity is under some number, just don't change direction

If it's above that number, choose direction

Make a rotator from X vector, then get its yaw, that'll be a single number representing the orientation. Divide by 90, round, and you got your int

[winged wigeon]

is there anyone that wants to have a 1 on 1 with me about blueprints ?

[faint pasture]

@bleak swift

[limber parcel]

https://blueprintue.com/blueprint/qn9_0pg1/

does this look solid or did i create an abomination?

its logic for flag capture in a CTF game

[faint pasture]

Why is it all spaghet

[limber parcel]

https://tenor.com/view/spiderman-gif-21558708

[faint pasture]

Are there many teams or just 2?

[limber parcel]

for now i just made 2 but i will make it dynamic i guess

for unlimited ammount of teams

[faint pasture]

I wouldn't do the fancy looping, just loop through and add to score if teams match

no need to early bail out on a 5 iteration loop lmao

[limber parcel]

haha ok xD

[faint pasture]

Also I would break out a TeamScored event

passing over team

then you can update score and do stuff like multicast events and sounds and FX etc

is Game Gamestate?

[limber parcel]

i did this now

[limber parcel]

Game is an actor which basically spawns and handles the game

its not really a gamemode

[faint pasture]

Sounds like Gamemode or Gamestate but you do you

[limber parcel]

i want it to be spawnable inside the actual gamemode

[faint pasture]

Component then

but if it works it works

I'd break out an Event Team Scored though

Then you could use it for other ways of scoring later

Game -> Call TeamScored

done

[limber parcel]

ok makes sense

thx for ur review

[faint pasture]

Just remember to keep logic where it lives. The goal doesn't adjust score, it just tells the game controller that someone scored and the Game actor handles it from there and does stuff

[limber parcel]

my current setup is like this

i have game actor which spawns a flag and team base actors

the flag itself handles the pickup logic

and the base handles the scoring logic

and game handles the initial spawning and respawn of flag

[true valve]

If I have a timeline in a variable how do you get the output?

[limber parcel]

if i pass a struct reference to an actor like this, is it actually a reference or will it make its own instance of that struct?

[faint pasture]

Structs are pass by value

I'm pretty sure

just pass the team name over if that's how you're indexing teams

the flag or goal has a team name string right?

[limber parcel]

the goal and players have

[faint pasture]

K

[limber parcel]

guess ive set this up in a very dumb way

[faint pasture]

So
Overlap -> if Player.TeamName == Self.TeamName -> Game.TeamScored(Self.TeamName)

[limber parcel]

why didnt i just make everything components of Game actor lol

REEEEEEEEEEEEEEEEEEEE

https://tenor.com/view/this-is-fine-fire-house-burning-okay-gif-5263684

ohh wait can i just add the flag and bases as child actors?

[zealous moth]

@limber parcel yes and actor components are also limited in what they can do

[limber parcel]

in which way?

[zealous moth]

For instance they cannot hold primitive components

Or other specific classes like a camera

[limber parcel]

they can hold entire actors

[junior hedge]

what do i add to a character for it to be able to be casted to as a character?

[limber parcel]

https://tenor.com/view/love-cocaine-spider-drug-jokes-gif-11949229

[junior hedge]

Character Blueprint

[zealous moth]

Should work

[icy dragon]

What's the warning says about it?

[limber parcel]

he is casting to the same class...

[junior hedge]

it doesnt inherit character

[zealous moth]

Should work still

[junior hedge]

ik why

[limber parcel]

did you even make the character class the base of your class?

[junior hedge]

i accidently made controller

instead of character

[icy dragon]

What's the parent class of PlayerCharacter?

[junior hedge]

you intentionally trying to be confusing? lol

[icy dragon]

Also try Get Player Pawn

[vivid inlet]

How do I do this but with multiple widgets in the one reference?

My pause screen has multiple widgets depending on what buttons are pressed and if I press 'P' to close the pause screen but the other widgets are open they stay on screen.

[zealous moth]

???

[bleak swift]

Um maybe make it an Array and then use add

[icy dragon]

That'll be something for your pause menu widget to handle

[junior hedge]

create widget ui bp and drag them in

if i understand you correctly

[vivid inlet]

Is there a way to nest widgets within widgets?

[zealous moth]

@vivid inlet yes

[icy dragon]

Just put the user widget inside your user widget hierarchy

[zealous moth]

You can also tab widgets

[junior hedge]

itll be here

[zealous moth]

I forget what it is called but in a widget container you can have multiple sub widgets to pick from

[vivid inlet]

Ooooh I've been doing it all wrong. XD Okay, thank you guys! :)

[signal ibex]

actually this may be a question for the multiplayer channel

sorry

[junior hedge]

np gl

[vivid inlet]

ty! :)

[junior hedge]

okay actually now fr the cast is failing

Prints hello when starting the game

[limber parcel]

now my code looks alot less cancerous

but i had to add a cast

[junior hedge]

lol?

[faint pasture]

child actors are gross

[junior hedge]

if I run this my unreal crashes

[faint pasture]

You should just have an event on Game to handle score

Although IDK why your game controller has children actors, that's weird

[limber parcel]

well this way i dont have to pass the game reference to the base

[junior hedge]

does anyone know why my unreal crashes

when running that code

[limber parcel]

https://tenor.com/view/voeding-computer-explode-cp-zijn-pc-gif-14578849

[faint pasture]

Flag
Begin Play -> Get actor of class (MYGAMECONTROLLER) -> set variable

Later

Overlap -> LOGIC -> Get GameController -> CallSomething

[last abyss]

is the player character even loaded in when you are using the get all actors of class at beginplay in the level blueprint?

[limber parcel]

thats what i did at first

[icy dragon]

Finally got to use this again lol

[limber parcel]

why are u even doing this?

[junior hedge]

for I can use the character

[icy dragon]

Also this setup seem to be super jank. Get All Actors of Class then get at 0?

[limber parcel]

i never had to do this to use my character, it seems weird

[junior hedge]

there's only 1 actor? arrays start at 0

[icy dragon]

What's the rationale for that using Get Actor of Class at all in this context?

[junior hedge]

because it is in the level blueprint

[icy dragon]

[junior hedge]

thats not the problem tho

when I run the possess node it crashes unreal

[icy dragon]

It is the problem.

[limber parcel]

https://tenor.com/view/vodka-shot-drinking-gif-7412608

[junior hedge]

this runs perfectly

so its not

[limber parcel]

this weird add posessable must be the issue

all characters should be posessable out of the box

[junior hedge]

well I am just a floating pawn when I load the game

[icy dragon]

I can't rationalise with this anymore, sorry

[junior hedge]

this also works btw

[limber parcel]

sounds like u didnt set the default player character in your gamemode

[junior hedge]

yeah

[limber parcel]

whatever ure trying to do, add posessable is wrong

[icy dragon]

Why even using Get (All) Actors of Class for possessing character is just beyond my sane thinking

[junior hedge]

because casting it normally wasnt working

[icy dragon]

This is truly peak XY Problem syndrome

[junior hedge]

so rude for no reason

just leave

instead of solving my problem you just try to shit on my day

[icy dragon]

Okay, how about this, can you just say how your game mechanic is supposed to work?

[junior hedge]

i alr fixed it

just leave me alone pls

[icy dragon]

Whatever, it's your project, not mine 🤷

[heady jay]

How can I get a reference to a static mesh actor from a line trace? Thank you!

[icy dragon]

Break the hit result, and cast the hit actor as StaticMeshActor (or Static Mesh Component if you detect for components)

Also Static Mesh Actor is really just a regular Actor with Static Mesh Component

[bleak swift]

What exactly do you want me to replace?

[limber parcel]

why is the value set to unknown class?

[faint pasture]

Step once

it might be an unknown class because it hasn't been set yet

idk

[limber parcel]

ohh i found my issue nvm

[faint pasture]

The whole way you're choosing a flipbook

bake velocity down into a direction, then select based on that

Velocity -> yaw -> int -> select your enum or flipbook directly

[heady jay]

Thank you a ton. Problem is, I'm trying to go from Hit actor to "Static Mesh Object Reference", which I tried by casting to StaticMeshActor, and then to Static Mesh, however a warning pops up.

[faint pasture]

The error tells you the problem

A static mesh actor is NOT a static mesh

it HAS a static mesh

rather, a static mesh component, which has a static mesh

[bleak swift]

So all of this

[faint pasture]

ya

[heady jay]

That makes a lot of sense. Thank you

[faint pasture]

Yup
VelocityVector -> Yaw -> Divide by 90 -> Round -> select

[bleak swift]

So every select should be replaced with this method?

[faint pasture]

That will reduce it to the -2 to 2 range, or maybe the 0 to 4 range, not sure which

[faint pasture]

You can select down to an enum then use the enum going forward

select enum on int, then from there on you use the enum to select stuff

or use the int directly

but calculate it only once per frame

There's 5 options because -2 and 2 are the same rotation

just like how -180 and 180 are

But you can select enum from the int, then just use the 4 enums later. The first and last option would select the same enum

[bleak swift]

Wait so is each Option a reference to a flipbook?

[limber parcel]

the score variable in my struct doesnt seem to update

[faint pasture]

Choose LastMoveDirection based on the int you calculate

then the rest of your code should work as is

Select LastMoveDirection based on Round(Yaw(Velocity)/90)

Not based on that boolean rat's nest you have right now

Then all your animation stuff can select Flipbook on LastMoveDirection

[bleak swift]

So remove all of this

[faint pasture]

Yes

[bleak swift]

Keep this?

And connect the return value of this to Set LastMoveDirection

[faint pasture]

@bleak swift

You might have to do some math to get int to map to 0-4 but you get the picture

my enum is construction mode but you get it

First print the integer that spits out to see if its the -2 to 2 range or 0 to 4 range

you'll have to add 2 if it's the former

or add 180 before dividing, either way

[limber parcel]

what am i doing wrong?

struct refuses to update values

[faint pasture]

Structs are weird, you gotta save it back in

Read, modify, write

[limber parcel]

so i have to set the struct to the output of set members thing?

[faint pasture]

I'm pretty sure anyway, I know structs are weird in BP

[faint pasture]

ye

[limber parcel]

this is cancerous lol

now something else broke

it adds 2 score instead of 1

[dusty wind]

The print string shows it increasing by 2 every score?

[limber parcel]

yes

apparently only the print though

[bleak swift]

I did this and Left and Up work but Right and Down still play the up flipbook

[dusty wind]

Can you show the whole function

[limber parcel]

guess i have to give it the score from break instead of from the add

yeah that worked

[faint pasture]

Print the output of that round

does it go down to -2 or 0?

try all directions

[dusty wind]

Yeah because it’s reading the score after you add it and then adding another

[bleak swift]

Only Left says -2

Every other direction says 0

[faint pasture]

K then work your way back, print the yaw

does it seem to make sense?

[bleak swift]

Left Print's 180 and all other directions print 0

[faint pasture]

dafuq

Does velocity seem to be printing the correct values?

Try GetRotationfromXVector and break out its yaw, maybe that GetYawPitchFromVector isn't working.

[bleak swift]

RotationFromXVector?

@faint pasture Well I tried that and the same thing still happens where only left reports 180 and other directions are 0

I can tell by you saying "dafuq" that this isn't supposed to be happening

[faint pasture]

Are you moving in X/Y or X/Z or what

[bleak swift]

My character moves in X/Z

[faint pasture]

lmao

that's the problem

Rotations break down in X/Z as pitch can't loop over. Why'd you pick Z?

Anyways, you can work around it by rotating the velocity vector before getting its yaw.

Roll it 90 degrees and it should work

[rare gale]

Anyone know the difference with interfaces in Blueprint in UE5? I had an issue converting a UE4.27 project so I'm having to rebuild from scratch with copy/pasta and interfaces don't seem to allow you to make a function anymore? I had interfaces with input pins, but the default event style now doesn't allow for that. Am I missing something?

[rare gale]

Figured it out. Didn't have the inputs and outputs set in the Interface itself. It's been a while since I set these up new, forgot about that part.

[topaz scaffold]

Is there anyway to sprint while swimming?

[faint pasture]

The same way you sprint when walking

[topaz scaffold]

Thanks. Super helpful.

[spare folio]

hi, is there a way for one-sided physical interaction between two physical actors? Lets say hitting actorX with actorY will make actorX fly away, while hitting actorY with actorX will result in actorX bouncing off (as if actorY mobility was static), I am trying to solve problem that I am having hard time finding solution and this could be a way, but never saw anything like this done before myself

[bleak swift]

It works except I can't seem to get the Down animation to play no matter what order I put these in

Anyways I'm not sure what this was for but the primary issue still exists

[faint pasture]

You need to make sure the range is 0-4

if it's -2 to 2, then add 2

[quiet shuttle]

I'm new to meta sounds, are you able to call blueprint events with meta sounds?

[tawdry surge]

Looks like it
https://docs.unrealengine.com/5.0/en-US/metasounds-the-next-generation-sound-sources-in-unreal-engine/

[bleak swift]

Fixed. Anyways so what was all this for?

It hasn't seemed to fix the issue in the video

[tight schooner]

Off the wall idea but make one actor's mass huge? Or have some BP logic disable physics sim in the event a collision with the 2nd actor occurs. Idk how well either of those will work.

Or thirdly, if it fits within your design, animate the other actor without physics sim at all — just math-based movement

[faint pasture]

Are you following what this is doing or just copying along? You have a velocity, you want 1 of 4 direction enums.
Convert velocity to a yaw or compass heading, divide that by 90 and round to get your north/south/east/west/up/down/left/right

Start with the first bit, make sure that the float output is giving a distinct number for all 4 directions you're moving it.

It's complicated by the fact that you're moving in X/Z and not X/Y

[bleak swift]

No No I understand that I'm just wondering what difference this is doing then my other way

[quiet shuttle]

Oh it looks like meta sounds can implement interfaces, thanks for the article

[faint pasture]

The difference is your other way breaks down as it prioritizes some inputs over others and doesn't really respond to the actual state of the character, which is the last direction it was moving in

that's why you were having your bugs

[faint pasture]

Using physics or?

Uh what are you trying to do?

like
pow pow pow ......................... pow pow pow?

Probably a timer and some function for iterations and random time range

well it's decimal...

Do you HAVE to fire the event 5x or can the event have a loop count parameter?

Wait a second, if you hit this 5x will it create 5 timers?

[quaint geyser]

Nope

I tried it

Hacky trick - just having a sequence node with 5 outputs

[sweet knot]

Hello everyone. Can you please tell me how to animate the texture depending on the speed of the object? This is necessary to animate the tank tracks. To get something like this: https://youtu.be/KpeUaKUeuPs

blueprint does expose the FPaths

Ah

I assumed cpp due to FPaths :p

[harsh grove]

Hey there, I am trying to change the walk speed of a character depending on their scale and made an excel sheet for that.
https://gyazo.com/231ecedc2c6be5df37937951d38fafe8

I have been trying to do it in bp in this way:
https://gyazo.com/53ff3c05d9631fa9fe87a743187e5d34

the function is: y =829,93e^0,1201x

x is the scale of the character and y is the speed I would like to get from that point on the axis.

What am I approaching wrong? Help is greatly appreciated!

[gentle urchin]

what about just multiplying by self?

Guess it's not what you asked 😛

[harsh grove]

Well, it could work too, but how do I get the value at a random point for lets say x=17,5 from the graph as a float/string popped out?

[blissful widget]

(.5 * point[17]) + (.5 * point[18]) works if there's no supported method to do so

[harsh grove]

It looks like an interpolationor am I wrong :>?

[blissful widget]

Yeah, going off two distinct steps if that's all you can access

[harsh grove]

Is there a way to viszualize the function in unreal and search for the point on the curve based on the variable for scale? Lets say input "5.0" should give me a string message of 1550 then?

[gentle urchin]

you can do a print string on it , as you're doing

make a custom event

make it editor callable

add a parameter to test with

there's also the float graph thing that murphy just talked about

[harsh grove]

hm... it gives me an "inf" value when I use the value 5 for x. I am using the node setup on the picture before.

[gentle urchin]

but that's for a short timespan

[faint pasture]

Split the problem up.

1. figure out how to animate the material by feeding it a number.
2. figure out how to calculate the number by speed
3. hook them up together.

[faint pasture]

You trying to change movement speed or animation speed?

Do you want them to move faster or take slower steps?

[harsh grove]

Just the movement speed value at this point. I think once I can grab a value from a curve I will be able to sync that to the animation too

[faint pasture]

Do you want them to walk twice as fast if twice as big?

NVM i saw your post

[harsh grove]

Well, that is what I got working so far. But the issue is that I have an exponential increase in speed :D

[sweet knot]

Sorry, I downloaded UE a couple of days ago - I don't know how to do it yet. While it turns out only to animate the car

[faint pasture]

Why? It's not THAT exponential, why not just make it linear?

How did you generate those numbers in Excel?

[harsh grove]

Yes, but below the value 5 it seems to bring my walk speed into negative values. SO I am thinking my node setup is just wrong or I have lacking knowledge about functions

[harsh grove]

I set defined them by myself and abstracted the function from excel

[faint pasture]

I mean are you super attached to the really gradual exponential curve or is a linear one good enough?

[harsh grove]

Well, A linear could work too, I think I just need to know for now how to get a value from the graph depending on what scale is there inputted.

[faint pasture]

Then just use the same equation

But you're making this way more complicated than it has to be. Start with

Speed = 200 * Scale + 400

and tune to taste

or just make a curve

[gentle urchin]

^

[harsh grove]

Actually, yea. That sounds like a much easier approach.

Alright, tried, thank you very much!

[faint pasture]

I'd actually prolly make it a curve asset tho, then you can just fine tune it graphically and make it any shape you want

[harsh grove]

If I do make a curve asset, I would need to convert the timeline into a float range right? I mean thats what my intuition tells me....

[uneven geode]

someone have a tutorial or some approach of how to achieve a road following curve in unreal? like blender with nurbs curves

[faint pasture]

Content examples spline mesh road

[faint pasture]

Are you using a timeline right now?

[harsh grove]

No, was just a guess IF I wanted to use a curve asset. I would need to somehow convert the time range to a float range. Not sure if my guess is correct though

[faint pasture]

Time is the x axis of a curve

It's just a function. Put in number, get out number

[paper nexus]

Can someone advice please: I construct a set of trees in a construction script in a blueprint. Pretty simple, I spawn them with the "Add Child Actor Component" node. It looks good in the editor, but during runtime, the child actors are gone. Any ideas?

[harsh grove]

Oki thanks :)

[faint pasture]

Is there any specific reason you're doing any of that?

Do you need stuff done at construction script time?

What are you trying to do?

[paper nexus]

I am trying to create a wood from individual tree actors

I construct the wood, it looks fine in the editor. The trees won't appear at runtime, even if I put the init into beginplay, though

This is my blueprint

[faint pasture]

Child actor component sucks

Just spawn actors

[paper nexus]

I cannot spawn actors at construction time afaik

the node is also not availble in the construction script. And those actors will then not be grouped

That means, I might be able to remove the wood, but the trees will remain 😅

[faint pasture]

They won't if they are child actor components. Delete the wood and the trees delete too.

[paper nexus]

but if I use the spawn actor node, they won't be child actors, will they?

they will just be regular actors of the scene

[faint pasture]

Child actor component is just a component that spawns an actor and manages its lifetime. The actor lifetime is tied to the components.

[paper nexus]

wonder why it won't work at runtime, though

[faint pasture]

Idk, it's your code. It should. Child actor component is still gross though.

[paper nexus]

Well, I am not doing much

[gentle urchin]

Why do you need them to spawn on construct?

You want them to spawn on beginplay, thats where it matters

For testing / visual / editor stuff you can just expose an event to the editor

Mark it editor callable

[paper nexus]

I found the problem, I had "Is Editor only actor" checked 😅

Sorry to bother you with my errors

but thanks for taking the time 🙏

[gentle urchin]

We'd still suggest moving away from cac :p

[bleak swift]

Is there any node or way to tell the distance to another player?

[gentle urchin]

Find distance to is a node

[paper nexus]

well, I'd use foliage but the sprites are billboarded. The materials suck because shadows won't be correct when I billboard via material

Thus I billboard in a blueprint

[bleak swift]

How would I reference another player?

[paper nexus]

and UE5 can't do actor foliage

[bleak swift]

Would I just reference this Character BP and it'd ignore its self?

Nope.

[gentle urchin]

Use ISM 😄

[bleak swift]

It just grabs the distance to itself

[gentle urchin]

You need some way of finding out who you wanna compare to

[bleak swift]

Well I wanna find the distance of the closest player

[gentle urchin]

Any player?

Multiplayer?

[bleak swift]

Yes

[gentle urchin]

Theres trouble up that road 😅

Without a firm grip on regular concepts like blueprint communication.. friendly warning/advice

[bleak swift]

Any Slight idea where I should start with this idea

Let me sorta explain it

I disabled Player Collision and instead of you just walking over other players. When walking through them their character's sprite fades away for you

[gentle urchin]

You can still have overlaps without blocking

[bleak swift]

I mean I set my collision to custom and set Pawn to Overlap

Didn't disable everything

[fast egret]

Morning, I've setup a way to handle fov settings in my game instance. A slider in a widget control this, let's say I set it to 50 in this context. Works good 'til the point i die -> respawn. The value is then reset to 90 upon spawn. When I aim down sight and stop aiming down sight, the value is back to 50. Am I missing something? I've called the fov setting upon begin play of my character. Seems to be briefly overwritten because of something I'm not regarding. Perhaps lack of coffee on my end 😅

[gentle urchin]

Beginplay on char calls load FOV?

[fast egret]

Yes

[gentle urchin]

What happens on death?

Since the fov is reset

[fast egret]

FOV retains, once spawning fov resets.

[gentle urchin]

So you actually respawn the char

[fast egret]

Yes

[gentle urchin]

And this load fov is done in the character being spawned ?

Or in game instance?

[fast egret]

I tried to call "load fov" on spawn but the same behavior takes place

[gentle urchin]

If the latter, you must explicitly set the fov again likely because of new camera

[fast egret]

Hmmm. Thanks. Let me try this once again. Bit odd it does it ... Probably not enough coffee on my end or something (overlooking the obvious) 😄

[gentle urchin]

Try to load fov on the char beginplay instead

[vast crow]

oh god why, unreal engine, are you google?
(this is global search which is for some reason case insensitive)

[rugged edge]

is this "right way" to make players able to pickup/destroy objects with sound effect, it works but can i do it better? just asking cuz im new to ue

"DenaOtettu" means Snus taken or something if you are wondering

[vast crow]

I don't know about correctness, but your life would be easier if you followed naming conventions. Name object variables with comprehensible object name (how can an entity be called "SNUSCOMPLETE"?)

[rugged edge]

well i should learn to name things correctly cuz i can imagine how hard its to understand anything if i were to make big game 😄

[gentle urchin]

Lookslike the bool is wasted aswell

[uneven geode]

I have just came back from vacation i have this error to the same project i was working and i dont know how to proceed. any idea?

"already added key"

[rugged edge]

yeah it might be, but without it i had bug that made the sound play like 3 times before that gameobject was deleted

but now somehow it seems to be working

[tawdry surge]

Since you're never resetting it you'd save yourself a variable and a couple nodes with a "do once" instead

[rugged edge]

well i didn't know about "do once" so ty

im used to do things like in unity

[swift kestrel]

Whats the best way to do a aimoffset in a sidescroller?

[limber parcel]

https://blueprintue.com/blueprint/qh96zav3/

any idea why the multicast sound wont trigger?

[slender idol]

hey is there any way I can check to which plugin a specific bp node belongs to or is from?

[tawdry surge]

Chatouille posted on the forums

In Visual Studio you can press Ctrl+, or Ctrl+T to search for symbols or filenames.
Most of the time, blueprint nodes call an underlying C++ function of the same name. So press Ctrl+T and type the name of the node without spaces (eg. “ProjectWorldToScreen”) and you should find results very quickly.
If you are out of luck and get no result, that means the node was given a different name via the UFunction meta DisplayName="…". In that case you can launch a full search (Ctrl+Shift+F) for the node name and you should find it.
If you already have editor open, another solution is to copy the node and paste it in text editor. There you can easily find information about the function reference

[limber parcel]

the server runs the code but it doesnt seem to replicate the multicast to clients

and i dont understand why it doesnt

[limber parcel]

well then create a new mesh component and add it

[jaunty stirrup]

oh ok !

not posdsible as a static mesh

possible*

ah its a geometry collection

my bad

[swift kestrel]

I've tried multiple solutions, but all of them give odd numbers. Some of the solutions I tried could work, but there's probably a simpler option that I missed.

[rain egret]

I have been thinking, how costly are scene components?

Like let’s say moving 100 of them as attached components, is that costly?

You might remember the ships and how the performance dipped as soon as they moved. Each wall has 2 triangles , those triangles have one scene component each that serves as a access key to the mesh data

[limber parcel]

i guess its cheaper than moving them on their own

[rain egret]

i will try using sockets instead

[tawdry surge]

Sockets are much better for that

[rain egret]

on it chief

damn, cant create sockets at runtime

i will just use the location as a key

[maiden wadi]

The answer to this question relies on how many of the moving actors you have. 1k moving actors with 5 components is probably about the same as 10 moving actors with 500 components. It's the same number of movement calls mostly.

[polar violet]

looking for some assistance; any help would be appreciated. https://forums.unrealengine.com/t/help-requested-character-does-not-rotate-while-standing-on-a-platform-that-is-currently-rotating/585568

[rain egret]

300

i dont see any problem with my new method, instead of using a actual component as a key i rely on the location and just transform it with the ships transform to get the actual location

hrmm

[tawdry surge]

Are the frames dynamic too, or are they single static meshes

[rain egret]

all procedural mesh

it turns this into a wireframe structure

adds wall and flooring and if sockets are available can even outfit it with modules

oh you meant the movement type

they are movable when attached

i could change that after i figured out how to less explode my ship

[gentle urchin]

Proc mesh hmm

Wasnt that one slow aswell ?

[icy dragon]

I wonder how does it compare with UE5's proc mesh tools

[faint pasture]

Do you have directional gravity working with the CMC?

[rain egret]

oh i fixed that, generating it is not the issue, the issue was that i created all in one go. now i am using a foreach with delay inbuilt

now this is weird. green is where floor actor is spawned, yellow is where procedrual mesh component of floor actor is located and purple is the vertice data that is created. they all fit perfectly, yet the actual flooring is offset like this

vector math yay

rotating the generation causes this

[gentle urchin]

I ment the component was not very performant

Not slow at generating, but slow in general uses aswell

I may recall incorrectly tho

[rain egret]

now thats interesting, after replacing the scene component with a simple vector the performance of 12 ships is still below 30 during collision

[ocean gate]

Hi! I'm trying to play a sequence but I want to do it from my Game Instance and not from the level blueprint. But I can't drag and drop the sequence from the level into the game instance, what am I doing wrong?

[rain egret]

given the walls still dont work cause of some vector math fuckery but this seems to be great progress

[rain egret]

i dont know and i havent tried but maybe sequence is not supported in what you are trying to drop it in

its like being unable to use delay in a function

[ocean gate]

well I figured that but is it possible to cast to anything to get that particular sequence or something?

*cast to the level blueprint or something

from the Game Instance

or I could just do it in reverse

but that's a bit annoying

[gentle urchin]

Theres some runtime procedural mesh component that i think is better performing

[broken quiver]

is it possible to have lets say i got one mesh. I made two git repos. One got mobile port version and another got pc port version. Main gameplay mechanics is in primary or other repo. In this way, can i support multiple repos?

[rain egret]

yea but thats no longer getting updated

so thats not an option, frankly i dont think the procedural aspect is the issue here

[zealous moth]

how can you check if a key or button (on game pad) is tapped or held down?

[gentle urchin]

Use the dot product of the input

Jk

[zealous moth]

HAHAHAH

oh you

[gentle urchin]

Isnt there a "is key down"

Or button down

If not, just track it manually

[zealous moth]

down

cannot find that

[gentle urchin]

Pressed?

[zealous moth]

hm, what context?

ohhh

i see @gentle urchin

different targets

bleh

[gentle urchin]

Same target, playercontroller

Otherwise manual is the way

[polar violet]

Yep I have directional gravity working with the character movement component.

[cyan bone]

Is it possible to have an impostor moving. If i combine the impostor plugin with the flipbook?

[zealous moth]

I guess those two functions do work however the idea is that I want to have different behaviours if I lightly tap a button vs press it and hold down...

Any ideas?

[gentle urchin]

Cant you use the actual input event for that?

Put a delayed branch to it

[zealous moth]

hm

@gentle urchin what is that called?

all i see is branch

[gentle urchin]

Its just a branch

With a delay in front of it

Well

How exavtly do you want it to behave ?

Just to make sure

Should the variable action happen on release ?

Or when pressed long enough / released fast enough?

[faint pasture]

That's not what casting is

[zealous moth]

@gentle urchin I have a ball and if I light tap I want it to bounce but if I hard press I want to ground pound

[gentle urchin]

On pressed -> set bHeld(false) -> delay -> set bHeld(true)
On released -> branch(bHeld) -> true if it was held for duration, false otherwise

Your branch outputs is where you do logic

This assumes actions happen on release

If you want it to happen during hoold then you must alter a few things

On pressed -> set held to false -> delay -> set held true -> ground pound
On released -> branch on held -> false -> try bounce

[flat coral]

Is it better to do zooming in by changing the camera's FOV or by moving it forward? Or is there some smarter way to do it?

[faint pasture]

Those accomplish different things

A zoom is a change in FOV

Do both at the same time for a dolly zoom

https://tenor.com/view/jaws-dolly-zoom-classics-gif-12429391

For the classic aim down scope, that's a FOV change

[flat coral]

Yeah ADS is pretty much what I'm going for

[icy dragon]

I have this kind of fascinations with dolly zoom, makes a scene looked more unreal engine

[solid belfry]

Can you use both anim blueprint and anim montage on a single skeletal mesh? For example,, to have an anim montage a node in an anim blueprint?

[icy dragon]

Yes, see Slots

The Slots is where the anim montage will be played in the anim instance. If your anim graph didn't make use of it, nothing will happen

[faint pasture]

A slot takes an input pose, and returns that pose OR the montage, depending on if a montage is playing in the slot

so it's like a conditional override of the pose

[solid belfry]

Thanks

[faint pasture]

There's blending stuff too, like you can only play the upper body part of a montage or whatever, so you can punch while running etc

[solid belfry]

I looked into montages because I needed to be able to immediately play an animation in my ABP in a specific state machine. And someone told me anim montages are the way to go.

[manic geode]

Hello. Can you tell me where is this '--' node in UE5? They changed it

[solid belfry]

Yeah, There are many YouTube tuts on this, but unfortunately not on other aspects of the anim montage, such as logic.

[zealous moth]

nice!

[solid belfry]

Maybe try remove the context sensitive option to see if it blocks it

[manic geode]

the what?

ah no its not there

[solid belfry]

I don't use UE5 so can't suggest you anything further... Good luck!

[ocean gate]

Hi again! Is it possible to move "Player Start" somehow whilst in-game? Using blueprints I mean

Or do I have to make a custom spawn system

[flat coral]

FWIW I don't even have "player start" in my level, I just handle spawning otherwise

[faint pasture]

Well that's tutorials for you.

[flat coral]

You can spawn a pawn wherever the heck you want, and then just possess it

[ocean gate]

yeah that's what I guessed

Ah possess was the one I was thinking of! Then it isn't too bad I don't think

Thank you

But I just want to use anim montages in my abp. For example, to have one state playing a reloading anim montage.

[cedar sparrow]

is it possible to convert a bp project to a cpp project?

[flat coral]

Correct me if I'm wrong guys, but I think when you pick CPP or BP project you're just picking which version of the base content UE should generate

If you took all the BPs in a BP project and converted them all to CPP, then it's a CPP project I think

[tame pecan]

yes

[gentle urchin]

Anyone recall what murphy uses in his blueprints to give him draggable "handles" for adjustments directly in the scene?

[trim matrix]

https://blueprintue.com/blueprint/z09lk7z2/
I'm making this BP Actor that Gets all actors of NPC class, then I did a For Each Loop and tried getting setting the NPCs var values into a character struct, my game instance has an array of character structs so i tried plugging it in there, then putting print string to check if it printed the id and name of the NPCs. The id of NPCs is set manually by me before entering the game, which works, but the NPC display name is generated by the NPC's BP on Begin Play but it's not working in saving that data because it just returns None when I try to print string it

I tried putting the display name generation in the construction script of the NPC bp, which makes it print a display name in the WriteNPCDetails actor's BP from the NPC BP, but it doesn't match the display name of the NPC (when I click on the NPC ingame i made a script to print its display name)

[mellow folio]

Is this multiplayer at all?

It sounds like you have a basic timing problem

When does this forloop run

Try making the forloop run a few seconds after the game starts?

see if that fixes it

[trim matrix]

no, sp

[trim matrix]

i tried it, put a delay of 0.2 seconds before anything fired in that BP. didnt work

even when i put the npc bp to generate random details from the construction script instead of on begin play the Detail collecting actor will store something instead of none, but itll be a different display name than the actual one on the npc. makes no sense at all

I thought that maybe im not casting/setting it properly to Array of character structs inside the game instance, but if that was the case how come it properly stores the id’s of each NPC? the only difference between id and display name is that the id’s default value is manually set by me in the editor beforehand

[trim matrix]

Ohh okay you were right, I set it to 1 second of delay this time and it worked!

Thank you^

[flat coral]

For something like a laser sight on a weapon, I know how to do a beam with niagara, but how would you actually add the laser sight dot to the world where it touches?

Maybe like a super emissive decal or something?

[icy dragon]

Either decal or a very small but long spot light

Or light probe near the hit location, but not exactly on it as to prevent clipping (add by multiplied hit normal vector)

[flat coral]

oh now that's an interesting idea. I wanna at least play with that and see how it looks!

[limber parcel]

whats the deal with these OnRep functions it generates?

[fallow umbra]

Hey, what's a better alternative to structs that's also replicated, I've seen that plain Objects could do the work, but these are not replicated

I've come across Components but are these reliable with a lot of data? Or are there better solutions

[grizzled ember]

What type can we put in a struct to accept both Material and Material instances ?

Matrial Interface, thanks !

[flat coral]

Unexpected issue with the spot light approach, it leaves this weird trail when moving

[tight schooner]

@flat coral probably temporal anti-aliasing. If the dot isn't a physical moving object with an opaque material then it probably doesn't generate motion vectors, which can produce ghosting trails when combined with temporal post-processing

[vapid ibex]

I'm mystified. My actor has a Collision Box, that has these settings, but in the game itself it is still intangible. What might be the cause of this?

[flat coral]

Step 1 is look at the collision settings of what you're trying to hit it with

[tight schooner]

If that's the case (try turning off TAA to see) then #graphics might have better suggestions on what to do. TAA has some parameters you can tune @flat coral

[vapid ibex]

It's the player, so nothing suspicious here, I think?

[limber parcel]

make it dynamic instead of static?

[trim matrix]

Is calling "Play Animation" the ideal way to do a specific animation? then do I have to reset back to the animation blue print after its done?

[vapid ibex]

It already is

[thorny acorn]

no, animation montage all the way

[trim matrix]

Can you elaborate?

[thorny acorn]

if you go to an animation, right click, hover over "create" and than make a montage, an animation montage will play and than instantly revert back to the animation blueprint or blendspace

[trim matrix]

ah, so you don't have to time each animation

and set back to your animation blueprint

after set amount of time?

[vapid ibex]

Thing is, this is another actor. It inherits from the same parent class as the problematic one, this box collider is inherited from the parent class. And it collides with the player just fine despite having identical settings with the problematic one (to be more precise, it had, before I switched it to "custom" to begin checking what's wrong with the it).

[limber parcel]

maybe u need to change some settings in the root idk

[vapid ibex]

This is the settings of the root.

[trim matrix]

I'm calling Play Anim Montage but it doesn't play. Is there something else which needs to be done?

When I call PlayAnimation it works fine, but not on Montage.

[thorny acorn]

did you link the mesh to target?

[trim matrix]

It said that it needed character

instead of mesh

[vapid ibex]

Ah, little shit, I got why it was not working. Apparently it doesn't work with negative numbers for SetBoxExtend. Once I put Abs node in here, it began colliding again. =_=

I remember having this in a diff project, try messing around with the Yaw

of the camera

[sonic crest]

no in the camera component

[vagrant oracle]

This is the code for the camera.

oh

good idea

[vapid ibex]

You need to clamp the resulting camera pitch rotation between 89 and -89, IIRC

Or 0 and 179, I don't remember

Though do remember that the values that InputAxis gives are additive, so clamping them won't work.

[tacit summit]

Hello Everyone, I'm relatively new to Unreal and I'm having some issues. So I've created a function that makes the player characters sprinting speed double with the use of a item. However it does not go back to its original sprinting speed. How exactly would I accomplish this?

[vapid ibex]

I guess item gives off temporary boost? So Add new custom event node, place a delay node with desirable time length, and after it put function that will return sprint speed to default amount (you'd need to write it in a variable before that). Then just call that event from the function that activates on the item pickup\use

[sonic crest]

tf is this? never ever had this issue

[tacit summit]

How would I call that function?

[vapid ibex]

Like any other function you've created? LMB on the node space and type in its name?

[daring vapor]

This is annoying as f. Been fighting it since I got an RTX3060ti a few months ago. Haven't found a fix.....

[sonic crest]

oh so I am not the only one

[daring vapor]

Yea, it's a known issue for both Epic and Nvidia

[sacred canyon]

is it not possible to overwrite save games? Ive set up a save system for customisation which works completely fine but saving the same one twice doesnt update it

[sonic crest]

https://www.nvidia.com/download/driverresults.aspx/147971/en-us/
try this

[sacred canyon]

even tried deleting and recreating the save, for some reason just messes everything up

[daring vapor]

Nice, I'll give it a go. Though this looks like a much older driver than the one I have....

[sacred canyon]

CAN IT NOT JUST OVERWRITE

whatever Im not fighting with this thing anymore

[sonic crest]

yeah I noticed, please let me know when you do if it fixes the crashes, someone recommended this to me but it'll take a very long time to download

ok I fixed it @daring vapor

the issue was RTSS

RivaTuner Statistics Server

Nice!

[deep geyser]

I need to debug a hydraulic network simulation, so I'd like to render some 3D debug lines for it.
What would be a easy way to draw debug lines, visible in VR and without being occluded by other geometry, i.e. like the move gizmo?

[gentle urchin]

How are you saving it...?

[sacred canyon]

just the normal save game slot thing based on a name the player will put in

I can easily just disable saving over an existing one and tell people to rename it for a new save, but overwriting would be nice though

[gentle urchin]

Well if all else fails, just delete it before saving again?

[sacred canyon]

thats what I tried, still the same result, or not saving properly

[gentle urchin]

Show some code i guess..

[sacred canyon]

its like it doesnt realise its deleted

idk what to show tbh because it becomes such a mess that I cant even get my head around it myself sometimes

but it does work other than that

[gentle urchin]

Got a feeling you're doing it wrong, thats all

[lapis violet]

So I'm putting together a Choose Your Own Adventure style project (with video files), and when I reach the end of a sequence, I'll have a GUI pop up with the options available to the player (clicking will result in a new sequence being played), but until they make their choice, I wanted the current sequence to loop between the time the GUI pops up, and when the sequence ends. What would be the best way to go about doing that?

If this isn't the right channel for this question, lemme know and I'll move it

[sacred canyon]

I assume so, but I was kinda asking in case overwriting actually isnt possible at all

but no why wouldnt it be

I even tried not changing anything because all it does is save into a slot name using the name you put in, so if you dont change the name, itll just save to the same slot, why is that a problem? god knows

[crude cradle]

hello, i'm having a weird issue.
I've got a widget ui, that has a function, which receives an array of structs. 🗳️

It loops over the array, gets a copy of the struct from the array, generates another widget, that has a function to receive that struct. ➿

That widget tries to break that struct and pull information from it, for example to update an image, or a text component.

HOWEVER, it logs out errors when doing that. Saying it is accessing "None" from the given struct.
FURTHERMORE, I have prints that use those fields from the structs that print out the actual correct values AFTER the above happens, 😕

so what gives?!
I've been stuck on this for awhile, at first I thought it was an issue passing the structs from server to client, or the for loop scope being destroyed, but then the prints shouldn't work, right?

maybe the above problem is resulted because I'm creating a local variable in a function with that essentially filters a bigger array of structs.

Is there a limited lifetime cycle for local variables sent out as outputs? that sounds like that shouldn't be an issue

[limber parcel]

[tawdry surge]

The local variables as output is fine.
You really shouldn't be doing all that in the widgets themselves

They're really only meant to display information

[limber parcel]

arrays of structs are cancer

[tawdry surge]

What are you talking about?

[unkempt hound]

Got a logistics question about where to store some data.

So currently I have about 20 pawns planned that a player can take control of - 4 at a time. I am currently storing the variables for ALL these characters in my Player Controller, so I can go grab the pawn information from the data stored there. However, I don't really NEED the data about all the other characters until I hit the player select spots in the game.

When I get out of character select, I don't need to load all the other animinstance data etc. while i'm playing with a squad of 4 characters.

Could a Secondary Player Controller just for the player select work for this purpose?

Have that be the one to load all the data when I go into player select, pass the information I need to the other player controller through the game instance?

[tawdry surge]

You wanna look up soft references

[unkempt hound]

Ooh

Reading up.

[faint pasture]

Data table with soft refs

[unkempt hound]

Awesome, that's how I'm loading them up already.

So basically when I create a variable for any object types, make them "Soft Object" types?

Some of the variables are structs, not sure if i can make them soft references?

[tacit oyster]

Hi everyone. Is possible to create procedural mesh component from a static mesh component at runtime? Thanks.

[faint pasture]

I mean it depends

if they are hard refs then they'll all have to be loaded all the time

whether or not that's a problem depends

Start with hard refs and make them soft later if needed IMO

[tacit summit]

As of this moment the characters speed does change from the boost to regular. however the change only happens after the sprinting key has been let go and toggled again. how would I make it happen without this?

[faint pasture]

Make a CalculateMovementSpeed function

call it every time anything that would change movement speed is activated OR deactivated.

[deep geyser]

Is it possible to record just my VR movement and input in UE when playing in the level, save it as a file, then playback in the same level so it operates the VR character, i.e. if when replaying, it's replicating my input, picking up items and using levers?
That way if I have a table with tools and devices, I can have a recording of their assembly, so when I update my blueprint or C++ code, I can retest the assemblies functionality with the recording.

[faint pasture]

Maybe but difficult

it'd be much easier to record the state of the world

and load that

so you could not record the actions that built the thing, but the finished product

The topology of all your connections should be a struct anyway, just save it to a savegame and it's done

That's what I do in my vehicle game to save/load vehicles

Array Parts
Array Connections

Initialize()
Done

[arctic notch]

Is there a way to get the button associated with an input tag? I am trying to show it in the UI from a Gameplay Ability

[deep geyser]

I've looked online through a couple of UE tools, but dunno if they could help:
-Take recorder - makes sequencer clips of added actors
-DemoNetDriver - logging replication messages to a replay, like the ones used in MP games.

[long whale]

hello, is there a way to add spline mesh component outside of construction script?

in a call in editor function.

this node gives warning if not placed in construction script and does nothing

[deep geyser]

what is the warning and do you even set the mesh and start and end?

I made a the same thing, but updating in a function I call in runtime when adding points

[cedar remnant]

Hi! I'm using the Enhanced input system and when I play on network/client 2 player mode my mouse input for looking around works only for the server and not for the client. All of the other input functionality works on both characters. Below is how I have my input setup on my player character.

[deep geyser]

What about having repNotify variables set by input, then in the repNotify function, run the code that the input originally did.
Recording my character with DemoNetDriver as a replay and running it somehow in the level?

[long whale]

The added component outside of construction script is always deleted after compile or editor restart. How to stop them from resetting?
Update: After some search I found AddInstanceComponent(UActorComponent* Component) does the job. Surprisingly this function is not exposed to blueprint as an option. Or maybe it's somewhere but I didn't see.

[faint pasture]

I mean maybe but one little error and it's a mess. Might be doable but I wouldn't guess it's worth the work vs just saving/loading the state of everything

[trim matrix]

Im setting a boolean called Stored? to true when the game stores details of an npc. problem is when i switch levels the boolean resets, how do i make it so that the boolean of the npc is constant as long as the game is open?

[tranquil gorge]

distance to opponent value is not consistantly reading. I even have it chained to the event tick. It just doesnt want to work. Anyone know what i can do?

[echo mist]

How can I open Pause Menu and close it with action mappings when input is set to UI only? Or is there another way?

[gritty plover]

Hey, is there any way to quickly check if all items in a boolean array are true, or do I have to check each one?

[tawdry surge]

"Contains" and check for false maybe

[echo mist]

I found out that there is a node called "Listen for Input Action". So when opening Pause Menu I disable input for player and in Event Construct of pause menu I listen for the input action but nothing is working.. How so?

[trim matrix]

I have an array of structs. an array of character_details struct basically. I want to make a script that finds IF ANY of those structs in the array contain a certain text in the first index of the array (which is a string) to fire a boolean

how do i do that?

Say if any of the character structs in the array contain "bob" in the name field, then fire boolean

[dense furnace]

@echo mist that event doesnt work when the game is paused ue supports normal input actions in widgets now though

*note that might only be for enhancedinput i dont remember but i know its possible now

[trim matrix]

Im storing the details of my NPCs by adding structs inside an array of structs, i dont want it to keep adding more than one struct for the same NPC though. so i want it to be able to find if that NPC's id/name is found in ANY of the elements inside that array of structs, to return a boolean, then i can branch it and make it not add another struct if its true/struct with the same id already exists

[echo mist]

I'm not pausing the game only showing Pause Menu and trying to disable players input but allow them to operate Pause Menu with keyboard too. I was googling for a quite some time now and I wasn't able to find one solution that would work

[dense furnace]

you can just have input in your widget now

no need ofr the listen

listen for input action also doesnt work if in ui only mode

[echo mist]

That was the first thing I tried but it still doesn't work, don't know If I'm doing some stupid mistake or why it's not working, tried both input action as well as key event

Also tried both UI only mode and Game&UI with disabling Player Controller input

[dense furnace]

add a input action but first call enable input on the widget

i think at least

i only played with it when they added it

[echo mist]

This is the only options I can see in User Widget

[dense furnace]

no i mean i node

enable input

like you disabled it on your player

[echo mist]

you mean node Enable Input in User Widget?

that doesn't seem to exist

[trim matrix]

How can I check if a variable exists inside a structure?

[faint pasture]

GameInstance

[faint pasture]

All properties of the structure exist. What are you trying to do?

[trim matrix]

I have a structure for an npc, i dont care about all the other variables i just want to check what is the name/id variable

and if it contains a name im looking for i want to do operations on it

[faint pasture]

Check if it's equal to whatever you're looking for

[trim matrix]

the name/id variable is the first listed variable in the struct if that helps

[faint pasture]

If NPCStruct.Name = whatever, do thing

[trim matrix]

yeah but the thing is i want to see if that variable exists in an array of those structs

[bold sedge]

Does chaos work well the city sample project? I keep crashing when trying to generate the chaos mesh

[trim matrix]

Not just one struct

[faint pasture]

For each loop

The variable always exists

That's like asking if X exists in a vector

It always does. There's no such thing as it not existing. You want to check if it's equal to some value

[trim matrix]

Thing is that's what i tried doing, i have for each loop for all NPCs that can be in a scene, then inside that loop element im running another for each to check all the elements/structures in the npc structure array, for each npc. If npc has a matching id name with ANY of the structures inside a loop, i want to return a bool

what i made is, if the id is matching it says its already stored it so it breaks loop. If it doesnt find a matching id it stores it/adds to struct array, then breaks loop. The problem is, is that the FIRST item it finds to not match, it runs the store script. I need it to check ALL items FIRST, AND THEN if no matching is found, run the store script. not just if the first or next immediate item in the loop doesn't contain it

@faint pasture

for each doesnt work, it needs to look at all of them first, not just sequentially because then it starts adding to the struct array the next immediate sequential item that doesn't match it.

See something like this DOESNT work (see image), It'll loop for sequentially through all the elements in the struct array starting from 0. Say I have 5 structure elements in this array, and ONE OF those struc elements is named "Bob", it's just going to check if element #0 is named Bob, if its not, then itll store it << I DONT WANT THAT. I need it to check every element in the structure FIRST to see if any of them is called "Bob" not just the next element in sequence, because then it starts firing when it shouldn't.

If the 4th element is named Bob, it's going to run through 0, 1, 2, 3 and fire "Bob does not exist, im going to create a struct named Bob then" for 0, 1, 2, 3. Instead of checking all the elements first to see if any of them are named Bob before creating the struct. With that faulty method its going to create a bunch of Bob structs first before reaching the index that already contains it.

@faint pasture

[zealous moth]

Why not use "contains"

[trim matrix]

Because 'contains' force checks all those other useless values, i dont care if the other values are matching or not, only the id

[zealous moth]

Oh that

You can remove pins no?

[trim matrix]

i dont think so

right click it and nothing says about removing it

[zealous moth]

I dunno If the issue is because you split the structure in the for loop but try to break it outside

[trim matrix]

it doesnt matter, it's still going to check for each sequentially instead all of them first.

[zealous moth]

The screenshot you provided before should work

So you don't want it sequentially?

Make a concatenated string and search it then

[trim matrix]

No. It doesn't. I tried it. Sequentially fucks everything up, because If I have 5 Npcs, and the 4th NPC is ID'd/named Bob, I dont want it to record another Bob because there already is a Bob, what sequentially/for each does itll check if the first NPC is named Bob, and since the first one isnt, itll create a duplicate record of Bob, and so on until it reaches the 4th. If I add a 'break' in there as soon as the record is made, itll still fuck it up and make a duplicate until it reaches the 4th index. just less duplicates than if not using a break, but still totally broken/useless

That's an example, in a scene I have dynamic varying numbers of NPCs, and Bob could be in literally any index number

[zealous moth]

Sounds like the issue is your order of operations

Why make it create then?

Run the loop as a function with a bool output

If false when completed then add

Like run the loop and based on presence create or dont

At the end of it all

[trim matrix]

what i had planned was if i have NPC bob, and he doesnt already exist in the records (records = array of npc struct), make a record for him (a npc struct)

[zealous moth]

Use datatables?

Make a copy of that instead?

Or like I said use a concatenated string

[trim matrix]

so make it run through the whole loop and see if a Bob exists after that?

[trim matrix]

what's that?

[zealous moth]

You have Bob Billy and joe

Bobbillyjoe

Search string for joe

If true do nothing

If false add Joe and add him to the string

So instead of searching a struct array you search a single string

Same thing

But different

[trim matrix]

i dont understand how concatenated string will help, a concatenated string is 2 strings into 1

So how do I make it so that if completed, and that Exists bool is still false, THEN do something?

[zealous moth]

Use the completed pin and branch it

Remember to reset your bool

[trim matrix]

Oh just like that

[zealous moth]

Reset bool

[trim matrix]

where do i put the reset

This is for multiple NPCs

[zealous moth]

At the end if it is true

[trim matrix]

This for loop is inside another for loop

It's inside the for loop for how many actors of class NPC there are

It's running that for each NPC

[zealous moth]

Should be fine, maybe make it a function

[trim matrix]

oh okay, ill reset it at the point once the loop is already complete if it was ticked on (since it's off by default)

Thanks.. I'll try your suggestions

[zealous moth]

Np

Hello, I am using "Distance Matching" which is contained in the "Animation Locomotion Library" plugin. The issue that I am facing is every time I close and re open the project, I have to refresh this node to compile successfully. I am not sure what could be the reason behind this. Any help appreciated, thanks

Also, I get these errors when I re open project!

[gentle urchin]

If inside a function, calling return inside the loop body effectively does the same in any kind of loop!

[open arrow]

Trying to initiate the Dialogue Tree without approaching the NPC

Tried this as well, didnt work

[gentle urchin]

You could have a global event bus for this 😄

I have yet to try it, but it sounds like a very usable thing for remotely activating events without fetching direct references to them

Also, as a note to your current test, if you ivalidate thenobject by settingnit to null first, surely nothing will be pointed to by it

You're setting the dialogue component to null

You simply want to "get" the component

I bought an asset the other day for this that works nicely.

Yeap, thats it

Thats exactly what i had in mind

Hey I have a question
I made a variable of animation montage, but it always be invalid even though it is substituted by a montage
How to solve it??

Of course animation is not invalid, it's a completely good animation

[gentle urchin]

this is more in the realm of #animation #multiplayer

[limber parcel]

why does this compile but the other doesnt?

it worked yesterday but now it gives me compile error lol

[mental trellis]

Replace the node.

It's not even remotely correct with that error message. It's fubar somehow.

[limber parcel]

cursed node

i already replaced everything with float now lol

[high ocean]

How would you guys handle two UIs that have the same logic/functionality but one is designed for mobile and the other for desktop/tablets? I can't seem to find a decent solution and having 2 versions means double the work, bugs & fixes every time I touch them. Any ideas on how to divorce all widget logic from design/layout?

[limber parcel]

i wouldnt design games for mobile

[high ocean]

it's not a game, but we both know that's besides the point 😛

[limber parcel]

https://tenor.com/view/hide-the-pain-harold-tongue-out-old-man-meme-gif-17779122

[high ocean]

lol that's disturbing

[mental trellis]

Hello fellow pedant! 😄

[limber parcel]

why dont u just move the logic out of the widgets and use variables instead?

[high ocean]

That's the point - question is, where to move the logic and how would that translate into a uniform framework

[limber parcel]

idk i would move it to gamemode or whatever

[high ocean]

yea, "whatever" won't do actually...

[limber parcel]

you could also try game instance

[mental trellis]

Put the logic in an AHUD wrapper.

Keeps it all nice and UI-centric.

[high ocean]

gameinstance is full - hardly compiling - but I need something similar to gameinstance, i need it to survive level travel and singletons won't do either since they can't contain async nodes

[limber parcel]

make an actor with save/load functionality xD

[gentle urchin]

or a subsystem

[mental trellis]

Subsystems are singletons, surely?

They literally just got ruled out!

[high ocean]

@gentle urchinfinally, you got into it 😛 tell me more...

[gentle urchin]

crap

[high ocean]

oh... ya 😐

[limber parcel]

lol

[gentle urchin]

Didnt know they couldnt do async stuff 😛

[mental trellis]

What's wrong with gameinstance exactly?

[gentle urchin]

there's to much stuff there already

[mental trellis]

Have you seen ACharacter or the CMC?

[gentle urchin]

For sure

which one of the 13k lines you want to inspect

x)

[mental trellis]

If you want it to be less "busy" start putting stuff in sub-objects.

[high ocean]

it's full of stuff already - it's an older app/software and the guys used two, three versions of UI - I can't do that, I just... can't. It's too distressing for me 😄

[limber parcel]

sounds like u need to save/load stuff

[gentle urchin]

sub objects sound appropriate really

[high ocean]

that's done too with singletons as much as it was reasonable, we can't re-design the whole product, it's fkin huge

[gentle urchin]

then you dont need to compile untouched stuff whenever you mess around in the GI

[mental trellis]

How is that going to fix anything when you need async (I assume) actions to be happening between levels?

[limber parcel]

thats what she said

[gentle urchin]

ouf, sounds like you got your hands full with this app tbh

[mental trellis]

When you say you can't do async nodes on singletons, you mean blueprints, right?

[high ocean]

I got into a team that has been slowly working while learning so older code is bad AF

[mental trellis]

Because you totally can with c++ and if your project is this big, you should probably be using c++ for some of it anyway.

[gentle urchin]

Given that you can have its lifetime similar to the gameinstance aswell, I felt it was a good fit

[high ocean]

some stuff needs redesign, and I rly want to find a way out of multiple UI implementations.

[mental trellis]

You can implement the base elements and just arrange them differently?

[gentle urchin]

parent widgets with the overall implementations ?

[mental trellis]

I was thinking more 2 layout implementations, but having the widgets themselves unchanged.

[gentle urchin]

honestly just spitballing, because i got no clue what logic you're actually doing and how different they may be

2 layouts sound reasonable

thats what he wanted to achieve by moving the logic out of it I assume

[high ocean]

Ok, the only option I've thought of was making a layout-empty widget class for the functionality and have the two layout designs (mobile + desktop/tablet) rely on the parent's functionality - basically just drag functions around and feed them with what they need (button, wrapbox, textbox etc).

[mental trellis]

I'm not sure you're getting what I'm saying, but you'll figure it out!

[gentle urchin]

So whether its a parent widget, or a different implementation class, the result would be mostly the same as i see it

[high ocean]

I read after I stopped typing 😅 but yes, It's what I kind of want - base elements are the same, arranged differently. How? 😄

[high ocean]

yes, but parent widget fixes the requirement for extra comms + makes sure refs are always there when required
