blueprint

[main lake]

how ?

[dry sleet]

I don't remember what it's called and I don't have Unreal access at the moment, but we made an office chair that was constrained to the XY axes this way

[real notch]

https://gist.github.com/RWOverdijk/8f00b824af63c63088d5d6fcc923c761 👍 ? It works. Just curious about the code

[dry sleet]

Pretty sure it was just a couple of checkboxes in the primitivecomponent

[real notch]

By making my own 😅

[meager igloo]

blueprints so difficult :(

I have used PlayMaker on Unity before, but this seems so complicated

[hoary junco]

I found "lock position" and "lock rotation" in the constraints on an object but that doesn't seem to affect physics... I'm still able to knock it around on all 3 axes

[trim matrix]

I cheated and I still don't know what's wrong

[real notch]

How do I find the delay file?

Also, why? Is UBlueprintAsyncActionBase bad?

There are a lot of results for delay 😄

🤯

I found it by adding kismet, thanks

Oh I can just remove FindExistingAction

[heavy plinth]

Do you guys know how I can solve this?

[dry sleet]

I'm almost certain it has that effect on our case...

but I guess I'll have to look again when I open the project next time

[real notch]

Heh, funky. I'll still need the rest of the code for the delegate so it's really not that big of a difference with UBlueprintAsyncActionBase

[hard smelt]

TIL break rotator != break rot into axes

[real notch]

Okay that's cool. Got it working, and didn't even need an int.

#include "TimersLibrary.h"
#include "DelayAction.h"

void UTimersLibrary::DelayFiveEver(const UObject* WorldContextObject, float Duration, FLatentActionInfo LatentInfo )
{
    if (UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull))
    {
        FLatentActionManager& LatentActionManager = World->GetLatentActionManager();

        LatentActionManager.AddNewAction(LatentInfo.CallbackTarget, LatentInfo.UUID, new FDelayAction(Duration, LatentInfo));
    }
}

[heavy plinth]

Thanks yall

[open sorrel]

yo guys, is there any methodology for passing extra arguments to events/functions called by a CreateEvent node?

[versed sun]

You have to add Inputs to the Event /Function itself
If you dbl click the Create Event Node, it should take you to the Event/Function

but you probably cant edit that

[open sorrel]

yeah, if I add a param the CreateEvent doesn't expose it

[versed sun]

did you add it to Handle Room Loaded?

[open sorrel]

yeah, it looks like this now, it just doesn't have an input for it

[versed sun]

oh, there wont be Pins on the Create Event

you have to change it on the Binding Event Dispatcher

[open sorrel]

so I would have to create a child class of Level Streaming then I guess

well thanks! it helped confirming it 🙂
it's a shame it's not easier to add params there

[smoky solstice]

one of the nodes is different for me and it doesnt let me do what they did in this video

[worthy tulip]

i have a secondary manual camera, i am wondering what is the BP maths algo for following the actor manually similarly to character's camera algorithm. Any ideas please?

[undone bluff]

I am not sure what you mean, are you talking about control rotation?

[worthy tulip]

yes

it's another camera, i want it to imitate the same as player's default character camera rotation

[undone bluff]

that's just a vector variable the pawn class has

you can just get it from your character

[worthy tulip]

yea but i am controlling it manually, not copying it from the character

it's another camera

[lilac cipher]

Hello Guys, Does anyone know how i can make it so that when the Enemy Ai Catches me, the camera faces the Enemy like a jumpscare?

[undone bluff]

you want it to have independent rotation?

[versed sun]

Do you want 2nd camera to look in the exact same direction as player , or Look At the same place?

[undone bluff]

you can just directly rotate the camera, that's it

[lilac cipher]

is this for me?

[undone bluff]

the control rotation in the pawn only exists so you can pick and choose which component follows it

[undone bluff]

ah no, you need to get the look at rotation (there's a node for that) from your player pawn to the enemy, then interpolate to that rotation

[smoky solstice]

In my IKRetargeter there are 2 overlapping models. does anyone know how to get rid of the duplicate so i can see the animation properly

[undone bluff]

there, I found a forum post that does it

[sick sky]

since i overrided ChoosePlayerStart in game mode, "Play from here" doesnt work (even if i give null to ChoosePlayerStart)

is there a way to get this back ? (without removing the ChoosePlayerStart override)

[lilac cipher]

do i just copy this into my BP_ENEMY_AI?

[undone bluff]

yea, but I'd recommend you calculate these values first and set them as (local) variables, then run the timeline and use them

also I'd probably make it a function in the player character

[lilac cipher]

FYI, the game i am making is where the monster chases me if it sees me so it can come from my left or right or back so there is no precise rotation, i need it to face the actor or perhaps have its own camera activated

[worthy tulip]

i just want it works like how it works on default character's camera. Where it rotates orbit around the actor/character.

[simple field]

Why does changing levels break my game?
When I open both levels by itself in the studio, both work properly. When I start from the main menu and open the level using it, the game level is broken - my pause menu doesn't work, my zooming doesn't work either. And vice versa, when I start from the game level and using the pause menu I go back to main menu, the Globe that is in the main menu is missing (like in the pics I sent). Seems like a loading issue, I'm using Open Level nodes. Any ideas?

[undone bluff]

it's literally just on a springarm that rotates

[worthy tulip]

i see. i think i need to try see if i should add spring arm

[undone bluff]

without a springarm a simple scene component will do too, but I assume you'd want a springarm anyways

[worthy tulip]

alright, thanks i am trying to test it

[simple badge]

Which one?

[smoky solstice]

get control rotation. for you it looks like the first image and the second image is what i see

[versed sun]

Right Click on Return Value

also, one is Controller , one is Pawn

[simple badge]

Get the player controller first. Then get control rotation from it. Please check the whole video. Its a small one. It would help you

[limber citrus]

Hey guys, I was reading from a JSON file in blueprints, I have a problem reading "projected_cuboid". This is also how it's represented in cpp but I am not sure what's the problem

[limber parcel]

why are you even creating the event like this?

[pulsar epoch]

Hello everyone.
I have a project with the default FPS template and everything works great, but now I need to add an option to change the camera from First person to Top view, and rotate and zoom in/out.
What's the best way to do it? I tried to add a new camera to the character but that's bot the solution I'm looking for.
Can I change the game mode from the FPS template to the TopDown template with a press of a button ? if so, how?

Thank you

[limber citrus]

and this is JSON

[lofty rapids]

i don't think that particular type is supported in json ? an array of vectors

[limber citrus]

not rly sure, but as far as I can understand, this cpp uproperty is the same one in the JSON

[lofty rapids]

your trying to serialize the array ?

i have not tried json in unreal yet

[limber citrus]

I just want to read the values yea

[versed sun]

did you make the value?

[limber citrus]

no

[versed sun]

or reading it from something generated elsewhere

in the Get Field, is Value default a wildcard, or a Vec2D array ?

[limber citrus]

wildcard

[versed sun]

ok, its probably Get 0 = X value, Get 1 = Y value

[lofty rapids]

thats nice you can serialize a vector array and save it in json ?

[lofty rapids]

i guess if it's stored as an array of objects, that makes sense

[limber citrus]

it's an array of objects inside an object

[limber citrus]

but I will try this

[lofty rapids]

it's a 2d array

[versed sun]

not sure how your JSON plugin works , but mine would be like this

[lofty rapids]

there ya go, that looks like the structure in the json

[limber citrus]

hmm

I've actually tried a similar thing before, I was storing all the numbers in a float array

[lofty rapids]

your getting 0 and 1 of the entire array

[limber citrus]

it just stores the X values and not the Y ones

[limber citrus]

yes

[lofty rapids]

you want to like you were shown by ryck, to foreach and then get that as an array

because right now your just getting the values of the main field, which is showing weird but idk how ue stores its stuff

[open sorrel]

Because I'm in a function and I can't add a custom event in there... even if I abstracted those nodes to an event and linked an event in there, nothing would change in terms of adding parameters

not sure if you can make a "closure" in the event graph like in other languages like js

[pine trellis]

im trying to get a character to randomly spawn in multiplayer but its not working in the game mode, do I need RPC the player controller to do this?

[limber citrus]

it's all X vals, and it's ignoring the Ys

[lofty rapids]

show the code

[lofty rapids]

i mean your missing some stuff, did you see the image ?

they changed the arra element with as array

and then got 0 and 1 of that

still don't know exactly how it works, i'll be using it sometime soon

i know a lot about json, but little of unreal

but in there image it's a differenct color also

[versed sun]

the Get Field Value is not a Float Array , it is a JSON Array

[limber citrus]

u mean like this?

[versed sun]

almost

[lofty rapids]

but why is one blue, and the others green ?

different data ?

[versed sun]

which JSON plugin are you using?

[lofty rapids]

did you create this json ? or did you save it from unreal ?

[limber citrus]

it's created in cpp I think, I am using NVIDIA plugin
https://github.com/saratrajput/Dataset_Synthesizer/tree/develop/UE4.27.2

[limber citrus]

I have the free stuff

[versed sun]

hmmm, they might not be compatable with eachother

[lofty rapids]

i know that unreal doesn't support 2d arrays

and in the json is just a 2d array

although maybe some way to translate that from json to unreal

[limber citrus]

yea

someone should just invent json replacement, the world will be happier place and he will be a billionaire xD

[lofty rapids]

wdym json replacement ?

[limber citrus]

new tech

it's very annoying dealing with json objects

[lofty rapids]

well json works fine it stores arrays np

it's just that unreal has a hard time parsing it most likely

[versed sun]

well, it is doing exactly what you are asking it to do

you are asking to read an ARRAY value as a Number, so it is only grabbing the FIRST (X) number in each array

but , there is a 2nd NUMBER (Y) in the array , but you arnt asking to read it

[lofty rapids]

well if you look at it it looks like it reads the array as array of floats

so it's not reading it like in the picture you sent

[versed sun]

I think that plugin is not good, can find a way to convert JSON to array,number,string ect

[lofty rapids]

i would be curious to see the storage difference from one to the other

[limber citrus]

which is a good json plugin?

[versed sun]

I like VA Rest

i think it was $10-15 ?

[limber citrus]

wait I have it

but it's not installed 🤦‍♂️

[versed sun]

nice , it might have been a Free for Month

[limber citrus]

yea, I always get those

we love Epic Games in the 3rd world xD

[versed sun]

I bought $50 plugin , and then it was free 2 month later 🙂

[hoary pasture]

Hi,
I want to ensure that A only has one actor overlapping and ignores the second one.
Same in the other way, The Overlapping Actor overlaps only on Box Collider, only A or only B not both at same time. I was thinking of a Bidirectional Map kinda thing, any ideas how to approach this.

[limber citrus]

25/m is not the worst xD

but yea always a heartbreak

[versed sun]

yah , but i havnt used the plugin yet ...

[limber citrus]

lol why did u buy it for xD

[versed sun]

I installed it and tested it , had plans to use it , then changed projects

Advanced Locomotion or something

[limber citrus]

ah the animation one

I think I got it free xD

[lofty rapids]

i'm not sure what you mean ?

[hoary pasture]

so if two actors overlap Box Collider A, I want to ensure that only one is registered as currently overlapping and
if two Box Colliders (both A & B) are overlapped by an Actor, I want to ensure that only Box collider one is registered as currently overlapped.

my brain has frozen, I don't know if it makes sense anymore

[lofty rapids]

wdym "registered" ?

[versed sun]

Event Overlap> Branch(Already have something registered?)
True = Ignore
False = Register Actor as Overlapping Acror

[hoary pasture]

Detected ig

[lofty rapids]

when are you finding if it's overlapped ? or you want it to not trigger the overlap at all ?

[elder pebble]

Hello, I am struggling with a List View UI widget. I have figured out how to populate the entries using an array, but now I need to figure out how to delete a single entry based on a variable passed from a box collider. i.e. Player enters box collider of BLUE object, presses interact button, then the word Blue Object is removed from the listview. I have no idea how to "find" the Blue Object line within the listview so that I can reference it in the Remove Item node. Any help would be amazing!

[lofty rapids]

so the array is of textboxes or something ?

[elder pebble]

the array is just a variable that I have populated with 8 entries.

[lofty rapids]

what are the entries ?

[elder pebble]

text

[lofty rapids]

so you can actually get text of one correct ?

[elder pebble]

those get passed to the list and create a listviewentry

yes

i need to be able to parse the list for specific text

[lofty rapids]

so if you take one out of the array, then this would update ?

you would just have to rerun the code ?

[elder pebble]

no. the array has 8 items, I pass a random 3 from that array and create 3 entries in the list. I then want the player to interact with those specific 3 items in the world and delete them from the list as they do

Maybe it would make more sense to pass the 3 items into a different array, then just have the list always show whats in that new array, then I can remove from the new array... but I struggled with that. I found it easier to just populate the list directly. I am very new... if it wasnt obvious! 🙂

[lofty rapids]

can you clear the list ?

because that would be a hacky way to do it but it would work, i just never done it so i don't know about listview

but you could clear it, then repopulate with array

after deleting

but seems f'd when you should be able to find by text

maybe a way to loop through and check the text of the list item

[gentle urchin]

RemoveEntry or smth

[limber citrus]

how did you get the AsArray node? I cant find it anywhere
can't also find it in plugin docs

[elder pebble]

there is a removeentry node... I just dont know how to pass in what I want it to remove lol

[lofty rapids]

^ where you could save the index of the item, and get it but again its just a guess

[versed sun]

Context Sensitive off

[gentle urchin]

The thing to remove should be provided by your example blue box

The identifier of that thing

[elder pebble]

Yea I assume I would add a property to the collider that identifies it as the BLUE item, but how do I tie that identifier to the text equivalent in the list? I dont know how to "parse" the list view to see if "BLUE" is in it, and if it is, remove it.

[gentle urchin]

isnt there a contains

let me open editor..

regular listview?

May i ask, why use that for 8 entries ? 😄

[elder pebble]

well its for a variable amount of entries ultimately. but probably only 2-8.

its a sort of objective tracker

is there a better option?

[lofty rapids]

can you put variables on the bp in the listview ?

[gentle urchin]

Listview is kinda optimized for massive amount of entries, and is a bit... different than most containers I'd say

[versed sun]

not sure what "Blue" is , guessin string

[gentle urchin]

text

but yeah

that works

[lofty rapids]

i would use break

unless there will be multiple

[gentle urchin]

(wrap it in a function, and return early) 😄

[versed sun]

dunno if there is way around cast, you should only have one choice for it to be

[gentle urchin]

cast is free in this case beyond the coupling,

its a parent widget, so I'd say its fine

you could ofc

if the list view is made in sync with your text list

find the correct index there

and just get that singular index, and remove the item

[lofty rapids]

i would also cache the results

before looping

a little performance boost

[limber citrus]

any idea? both gives same error

[gentle urchin]

avoids the loop , but requires sync

[elder pebble]

OK this looks like a lot of things I can try! I am seeing some nodes there that I didnt know how to find before and I think they will help me.

[versed sun]

What is Path?

[lofty rapids]

this error says that your path is incorrect, it can't open the file

i think it's different before it was something about the format

[gentle urchin]

here we go

with some safety

[limber citrus]

it should be a valid path

[versed sun]

make sure you use all "/" and not \

[lofty rapids]

it's saying "can't open file" so it may also be open somewhere else if it exists

[versed sun]

also, you can use Dir

with an Append

[lofty rapids]

i created my own root dir in c++ that gives me a test directory for development, and the root directory when shipping

because idk about blueprint but the root dir i got in c was always a pain in the ass to work with

i'd rather use d:\sometestfolder\

[versed sun]

Something like this

Uncheck Is Rel to Content Dir also

[trim matrix]

hard coded ref should be avoided

[limber citrus]

okay, I did but not the same way, cuz the path I want to access is not in the same as the project I am in

[versed sun]

make sure to use / , NOT \

[limber citrus]

yea

I am gonna need to replace all my old code with the VR Rest code

I had already done some things

will try to recode them first before accessing the "projected_cuboid" array that was making trouble

[lofty rapids]

i mean wouldn't you want to know that works

before you go changing everything ?

[limber citrus]

yea

u right

my brain stopped working, working while fasting is not the best thing xD

[meager igloo]

How do I get reference of a blueprint inside another blueprint?

[lofty rapids]

what kind of bp ?

[versed sun]

Keep in mind , plugin JSON A and VA Rest JSON will be different formats and not interchangeable

[limber citrus]

yea

[meager igloo]

I have a pawn that has 2 other pawns inside the blueprint, i would need to get references to them

[lofty rapids]

2 other pawns as component ?

wdym "inside them" ?

[meager igloo]

yes

[lofty rapids]

they should be just able to drag onto the graph

you want to access one of it's components from itself ?

or am i misunderstanding

[meager igloo]

i have a vehicle Pawn that has two other "vehicle" pawns as blueprint components to act like the front and rear axle

one in the middle is the main vehicle and i should be able to set variables in the other two

I can control one of the "axles" if I set that pawn to be automatically possessed.

my car is made like this since i couldn´t figure another way to do it https://www.youtube.com/watch?v=7LLSRprsBK8

[versed sun]

Also, Make yourself a Blueprint Function Library for all you JSON conversions
It has a few JSON conversion built in , but you need to finish them

[meager igloo]

I can drag the BP components on the event graph of the main "car", but I don´t know how to set variables in them.
I have a public "steering" float in the front axle that I want to be able to set

[kind moth]

Hi! i need to use a get (a copy) node to get an array element with an index. but i am working in control rig and this node doesn't come up. Any alternative methods? thanks!

i got it no worries!

[lofty rapids]

you tried dragging out and set variable, get variable ?

[meager igloo]

there is no such thing

[lofty rapids]

is it a seperate bp as a component ?

actor child or something ?

maybe you can cast ?

[limber citrus]

is there a blog or something covering the main functionalities of the plugin?
it's official docs seems not the best and I feel like I am missing a lot of info on how to use things together

[versed sun]

i dont remember anything
I get a little confused on what's a JSON Object Object , and what's a JSON Object Value

[timber crystal]

Hallo friends i hope you doing well 🙂
When player is death i want that the huds disappeare

It works with the player hud but not with the handyinputs or the boss health hud (widgets)

im trying it in the player BP

[smoky solstice]

How do I make the animation for my characters jump less choppy and weird?

[trim matrix]

eww

[timber crystal]

did you try this?
https://youtu.be/qbgDaRo312k?si=3d5xOHyKD3iQ05H1

[smoky solstice]

yeah i did

thats what i followed

[lofty rapids]

looks like your transitions are off maybe ?

[smoky solstice]

this is what ive got in here but im really new im not sure what anything means really

so im not sure how to know what transitions are off or anything

[lofty rapids]

you might get better help in #animation

[smoky solstice]

ah thank you

[lofty rapids]

you see the lines going to each node ?

theres white circles there, if you double click i think it takes you to the bp for the condition

i had the same problem with a tutorial it wasn't working correctly had to make mine custom

it is structured correctly i'm just guessing your transition is wrong but i'm still learning

[cold sinew]

hi, I have 28 Timers looping when beginplay .. the interval between 1 - 0.01 sec how can I optimize it please ?
I have Call time , 10 ms How can I keep timers ticking but optimized ? Thank in advance

[smoky solstice]

yeah i did that in the tutorial but im not sure if i did something wrong at some point or something i just dont really know why its like this

if you watch the video of the jump closely its weird since the jump happens before the animation does

[lofty rapids]

double click that circle

what does it look like in there ?

[lofty rapids]

what does your event graph look like ?

it must be setting is jumping at some point ?

[lofty rapids]

what about the transition from jump up to jump idle ?

is it automatic ?

maybe your actual animations are weird, the jumpup and down should be short animations

[smoky solstice]

yeah the one between jump up and jump idle is auto

and the jump up and jump down are short animations

[hoary junco]

how do you get the location of a mouse cursor? I'm using a system where the player is just a camera in a set scene, and I want to be able to pick up and move an object around in the scene

I enabled mouse input, I have a system going where when I mouse over an object it shows an outline (using Actor Begin/End Cursor Over), it registers when I click on the object (using Actor On Clicked), but idk how to get the cursor's location so I can move the object to the cursor for the drag part the program clearly knows where cursor is otherwise how would the mouse over events be working?

[lofty rapids]

https://www.youtube.com/watch?v=b1_efR9hrT4

[hoary junco]

I tried that already but I got a weird problem where the camera would jitter and then the mouse and its over location wouldn't line up

[lofty rapids]

hmm

[hoary junco]

like the thing would be acting like I was hovering over it even if it was to the left of the object

[lofty rapids]

you can do a trace

[hoary junco]

tried that too, same problem

[lofty rapids]

so was the problem the dragging part ?

you may have had some bad maths

[hoary junco]

so what happened with the line trace is it would shift the camera and cause the offset problem on click, I seem to have somewhat resolved that now, but idk what to do with the Event ActorOnClicked to tell it to detect when I'm holding down the mouse to dag the object around...

[hoary junco]

now I'm getting a weird problem with the physics object that I'm trying to drag.. if I use component movement to drag it anywhere it teleports to a specific location and won't move, but if I try to use actor movement to shift it then nothing happens... it's like the component and the actor are separating

[mellow dagger]

Hi everyone! I am kinda new to BP and I am currently trying to implement something to my game and cant seem to figure out how to do it..! And I really tried to search for cues but with no luck! Basically, my issues goes as follow: I have a pipe with 3 holes in it. In those hose, I have a scene component. My goal is to randomly spawn stream from the hole. The steam itself is a blueprint that randomly change the stream visibility. The issues is that when i'm trying to spawn the steam at the scene component location, they all spawn there instantly. In otherwords, im trying to make it so that in a custom event, the engine pick one of the 3 hole and choose one to spawn the stream. I was trying to use an array to store the location of the scene component but it wouldnt let me (or i dont understand how to)

[versed sun]

sounds like you are close , post the code you are using

[leaden sun]

How do you add localisation to data tables?

It seems possible for string tables but not data tables based on structs

[gentle urchin]

As long as its text fields it should be possible?

[mellow dagger]

I’m not on my computer anymore sadly. If I think about it later on I’ll post !

[hot lion]

Hello there, trying to get a pawn to behave like a plane when a flight mode is engaged, but i got some weird dragging and I cannot seems to find a way to influence correctly my forward vector, any hint ?

[versed sun]

dragging like stuttering? check for colliding components like static meshes

[hot lion]

Nah its not colliding with anything. For example if i do not input any forward vector' as soon as the pawn fly, it looses speed on its own.

I've got air friction to 0, and been looking up as someone suggested here to some kind of drag, but i cannot find it.

I have the same problem when i feed an input vector to the actor behaving like it has massive internia and not beeing able to make sharp turns, so theres a whole system i missing i guess

[boreal condor]

Hello Everyone. I have some questions regarding blueprints specifically when it comes to pawn sensing and setting up blueprints to access variables in another pawn.

[paper gate]

Is there any way to see whether a for loop was aborted or completed (as in all actions were completed)? The completed output is triggered regardless of whether the loop was aborted or has been fully completed

[meager igloo]

So I learned Pawns can´t receive input when unpossessed, but I heard if you add a Actor Component to the blueprint that can receive input.
So now my problem is how do I get the inputs from the Actor Component in my Pawn blueprint? xD

I would change the Pawn class to Actor, but I can´t, since it is the custom FGearVehicle class that I´m using from FGear vehicle physics

[heavy plinth]

Does anyone have an idea how I can solve this? I’m trying to edit note text in the editor using a public array text variable and it’s working for the first line but not the next pages

[lofty rapids]

whats only working for the first line ?

you only set the first page on begin play

when do you set the other page i'm guessing in the next page node ?

[heavy plinth]

I actually revised it so at the next note node on event interaction it increments the current page and sets the text for text box 2

When I fill out the text in the editor I make two array items (pages) and only the text from the first array item is populating in the note

[lofty rapids]

so you actually set the text and it didn't change when you went to next page ?

what does that code look like ?

[faint pasture]

aight so ask them

[boreal condor]

ahh my bad yes was just confirming this was the right place to ask, ill put together some screenshots and go in depth

Question Regarding viewing pawn sense lines in the level editor.

In this video tutorial you can see the "pawn sense lines" are visible in the editor.

in my editor the pawn sense lines are not visible.

I suspect this may be because of the way I have pawn sense setup Where the pawnsense is setup in BP_AI_Pyramid, and the Default_Pyramid refrences the BP_AI inthe AI Controller Class, but I am not sure

I know the pawn sense works because if i setup a print string it spams out "pawn detected"

[jagged violet]

hallo guys i'd ask you about thing anyone know or have docs for explain all blueprints in unreal 5 ?

[boreal condor]

Hey man i found a lot of that information here https://docs.unrealengine.com/5.0/en-US/

[jagged violet]

ty man, but I don't know where I found page in docs to the full sheet fo blueprints

can you help me ?

[boreal condor]

yeah im actually reading through them now trying to fix my issue
heres a direct link
https://docs.unrealengine.com/5.0/en-US/blueprints-visual-scripting-in-unreal-engine/

but in the earlier link i provided you can use the little search bar to the left over the index

[jagged violet]

first ty very much❤️❤️, secondly I want to mention my English is weak for that I found a bit tricky to search about what Iwant exactly

[mild ibex]

Out of curiosity is it possible to create a macro / function that can dynamically update a wildcards type? I doubt it due to the fact that UE is C++ but Im curious if anyone has tried before

[heavy plinth]

Here's the code for the pickup blueprint

Here's the widget bleuprint

[lofty rapids]

i see your setting the text on tick, thats not working ?

[dull shell]

What's the end goal

[heavy plinth]

Yeah unfortunately not

I'm going for something like this

[dull shell]

Does it change on Key press or automatically?

[heavy plinth]

It changes on key press using my interact interface blueprint

event interact()

The whole issue is that I don't want to use a separate button to close the note. I just think it would be more responsive if you can use the same key to interact with the memo, changing pages, and closing the memo like in the example

[dull shell]

Right so the problem rn is it's not changing page at all? Just shows the first one?

[heavy plinth]

Yeah exactly. At first I had a non-expandable note system that only let me switch between two notes but I changed the note text variable to an array so I add as many pages as I want

There's some variables you can't see let me take another screenshot

[dull shell]

When you press E after opening the first page, does it print hello?

Sorry whatever the Interact button is

[heavy plinth]

Yeah it does. That was just a check for me earlier to fix something with the interaction

I put a new print right now to see what the current pages text is and its doing something interesting

[dull shell]

Make sure your Interact Input has this box checked

[hallow compass]

im adding force to the main component of an actor on tick, and i would like to update the actor/root component's rotation to match the direction of the force.

But, if i try to set the rotation of the actor after the force is added, the rotation isnt applied. Is there a way to update rotation while adding force to an actor?

[dull shell]

Show your code

[trim matrix]

WTf

that's deprecated

you should never use it

[heavy plinth]

I'm using an blueprint interface to handle interactions so it doesn't let me check that but I know it works because I've been able to trigger widget animations when the game is paused

[lofty rapids]

you can check with a print string

[hallow compass]

here it is

[dull shell]

guilty of still using old input system for fast prototyping

[trim matrix]

how many actors are going to be in the world with that code?

[heavy plinth]

It looks like the text is being updated after the note goes away for some reason

[hallow compass]

just 1

its a little flying ai

[trim matrix]

I weas just wondering because if you'd use that one hundreds of actor, it wouldn't work lol

[hallow compass]

for some reason it used to rotate fine when using a shitty .02 timer but moving it to tick doesnt make the rotation work properly with physics?

[dull shell]

In the video it stopped printing

[heavy plinth]

I'm getting so close. It's recognizing that I'm accessing the second item in the array but I dont get why it's not updating the note text 2 with the current page after it's incremented

[lusty hedge]

WHY

i dont understand

im referencing the widget blueprint called main

[dull shell]

I think pause is the issue here. Just for testing purpose. Do not pause the game and check if it works

[hallow compass]

there is no point in casting to it if you're already getting it. maybe you just wanna check if its valid?

[heavy plinth]

When i uncheck pause game from my pickup note event

It still increments that current page but it's not updating the note text 2 for some reason

It does seem to be changing the text in the print statement properly when the game isnt paused though which is weird

[lofty rapids]

how often are you running updatetext event ?

since you had it on tick you wouldn't even need that, but it's set to only zero

not the current one

[heavy plinth]

I'm not sure actually I guess only once which would be a problem

That's because the update text function is in the widget blueprint

I can reference that event in the note pickup bp though and put it on event tick

[dull shell]

Try disconnecting the UpdateText event i dont see it being used anywhere

[heavy plinth]

It's being used on the event construct to point the text variables to the array

When I disconnected it, it showed the test text that I originally put in the widget text box

[lofty rapids]

so now you want to be able set it programmatically which for some reason wasn't working

[dull shell]

I see 2 Text Widgets, NoteText1 and NoteText2. Are you sure the one on top is NoteText 2?

[lofty rapids]

atleast you got a print string value

[heavy plinth]

That's what my widget animation is handling. When isReading? is true and the player presses the interact key again, the nextNote widget animation is activated

[lusty hedge]

i see. in that case im not sure why my interface is not sending a message

the print does not run

[hallow compass]

there is no point in using an interface call to something you are already referencing

just call the send text event directly from main

[dull shell]

Can you show both animations

[lusty hedge]

2 different scripts

[lusty hedge]

the 2nd screenshot is a different WBP

[hallow compass]

yeah, but you have a reference to main in your main widget, so you can call events through it

[lusty hedge]

i dont think i explained well enough and im having a hard time doing so

[lofty rapids]

so main is another bp ? you could check does implement interface

[lusty hedge]

main generates many instances of "squareWBP"

the square holds a button

i want to click that button. and send information it holds to mainWBP

i tried an interface but it doesnt even call

[faint pasture]

how does square know who to talk to?

are you setting Main?

[dull shell]

Did you add the Print string on Event Tick? That shows current page text

[heavy plinth]

Yeah that's what's popping up a bunch

[lusty hedge]

it should know who to talk to because of the interface

square ^^ (both)

[lofty rapids]

i think your using format text incorrectly

[dull shell]

I rewatched the video. Shouldn't it be showing Test Text 2 when you changed the page? Instead it still showed Test Text 1

I believe the problem is in the animation

[heavy plinth]

Yep. That's my problem

Ohh yeah I did change the animation

[faint pasture]

show where you set Main

[lusty hedge]

set it in square?

wrong reply

but yes engage i see that now. but i think that might be unrelated error

[heavy plinth]

Oh my god it works

[heavy plinth]

I literally spent the last week working on this 😭

[dull shell]

Animation was the problem right?

[lofty rapids]

ya it's unrelated, just mentioning it

[lusty hedge]

i use a hard reference in the variables of square

[heavy plinth]

@dull shell Yeah it was. I'd changed it at some point because I thought I was only gonna use one text variable

[dull shell]

Yeah you could also use one text too. But nice you figured it out Congrats

[heavy plinth]

Thanks for your help pointing that out. I really appreciate it!

[dull shell]

That's not how it works. You need Instance reference not Class Reference

[dull shell]

No problem

[faint pasture]

when do you set main? When does the child get told who to talk to?

[heavy plinth]

My second animation does get kinda fucked up when I have a third page so I gotta figure that one out

I think I'm just gonna make a new event for switching pages that starts with a text box with no opacity

[lusty hedge]

how do i target this instance?

its not an object

[dull shell]

Make a new Event in Widget BP and name it "Flip Page" it should have a Text as input. This new event will play an animation where NoteText1 fades out then after fading out Set the Text of NoteText1 and Play the Animation where the Text Fades back in.

That will be seamless without having to create animation for each page

[dull shell]

You have two widgets right? One where you try to call the SendText interface event. The Other "Main" that inherits that Interface?

[lusty hedge]

yes

one WBP called square and one called main

square is created inside main many times using a for loop

every instance of square contains a button

[dull shell]

Where do you create the widget "Main" whereever you create it just save it's reference and then use that reference to call the Interface event

[lusty hedge]

when button is clicked i want to use the interface to change a piece of text within main

[dull shell]

Ohh okay

[lusty hedge]

i understand now.

i forgot its actually being created

in a 3rd BP actor

uhg

[dull shell]

So when you are creating Squares in Main. Make sure to pass the Reference of Main to Square

[lusty hedge]

okay ill try

[lofty rapids]

i like to put the widgets in the hud

[lusty hedge]

this is in main

where squares are made

[lusty hedge]

^

[dull shell]

I think you may have to change the variable type.

[lusty hedge]

i thoguht so but i dont know what. its a Widget Blueprint

idk why this is the way it is ive never had these problems with interfaces

i should scrap the whole thing this is stupid. Must be an easier way

im simply sending an int from one WBP to another

[dull shell]

Change variable type to User Widget

Then try to assign the value

[heavy plinth]

I'm a little confused on the setting the text as input part for the flip page custom event

And when I was doing it I realized I had to make two animations for fading in and out

[dull shell]

Add a new Input Variable to the custom event and

it should be Variable Type Text

[dull shell]

You could use one. Play it Forward and Reverse

[heavy plinth]

Okay I made the forward and reverse animation and I added the text input variable to the custom event

Would this be replacing the note text array variable I already have setup?

[dull shell]

No it wont

[heavy plinth]

This is where I'm at with it rn

[lusty hedge]

@dull shell i got it. this is so stupid.

needed a generic object reference

[heavy plinth]

So you said set the text first, play the animation where the text fades in and out and then set the text again?

[dull shell]

that works too lol

[dull shell]

No play fade out, after Fading out completely set text, Play Fade In

[heavy plinth]

So there would be the need for two animations

[dull shell]

No just play the Fade Out Animation in reverse or if you want you can use 2 animations

[heavy plinth]

Oh dang I didn't even realize you could play them in reverse

Would it be like this?

[dull shell]

This goes here

[mild ibex]

Anyone here know how to use the instance struct from struct utils plugin? I keep seeing posts of what appears to be a dynamic struct in editor but is this a misunderstanding?

[dull shell]

Use this node for play animation

This is how it should look like

[heavy plinth]

It works!

You're the goat

[dull shell]

Glad to know!

[dull shell]

Perfect!

[heavy plinth]

Thanks again. I really appreciate your help @dull shell

[dull shell]

No problem bud! Happy to help

[mild ibex]

Bump 😔

[faint pasture]

does jumping SET your velocity or ADD to it?

if it adds to it, then you'd get the result you're seeing

[hoary junco]

how do you do a check in blueprints to check if a component is movable or not?

[faint pasture]

yeah it's probably a velocity addition

I'd dig around in the CMC to see if there's a setting

[silk cosmos]

Replace the jump node with a launch character node. It does the same thing but you can override the vertical velocity which is what you're looking for

[hoary junco]

I was looking up a tutorial on this and it was saying after a line trace, get the hit component, and then "get mobility" then do a == comparison with "literal enum EComponentMobility" with the variable set to movable, then the result of the == goes into a branch... but when I try to do that I get this

[loud vessel]

Does anyone know why would a physics constraint make the constrained object go to world location 0,0,0 ?

[faint pasture]

drag off Mobility and type Switch

I'd just switch on

[faint pasture]

probably constrained to nothing

defaulting to constrained to the default transform

[loud vessel]

So, I do have to constrainted to something.
that something is also valid.
Yet this somehow happens.
any idea?

[faint pasture]

show your component layout and your constraint components constrained components names

[loud vessel]

look at DM

[faint pasture]

What are you trying to do here, telekinesis?

like Grav Gun from HL2?

[loud vessel]

Sure, but I pre-select the bone, in this case the "Neck".

oh and i must use physics constraint.

[faint pasture]

You're trying to constrain neck bone to what? A cube?

[loud vessel]

Sure yes, an invisible cube, which is attached to the character.

[faint pasture]

I'd use a physics handle

constraints are more for constraining 2 simulating things together.
A handle is basically a grabber, uses a constraint under the hood

[loud vessel]

It doesn't do the same required effect I wanted.
I already tried.

I want the "Neck" to be PINNED to a location in space.
and when I move that location, the neck follows it.

[faint pasture]

You are 100% describing a physics handle

[loud vessel]

The physics handle takes into consideration how heavy the object is and all of that...
so it sways and springs a lot, and even glitches for me (the character deforms)

meanwhile what I want is for the object (In this case the head) to just be following a location, while the rest of the body is the one that sways.
So no swaying or free movement for the head, just the rest of the body.

Still, it doesn't make sense why the constraint in my situation breaks... and makes the body go to world location 0.0.0

If i can fix this, I'm good.

Imagine as if II want to say "Set actor location" but for a bone.
and I do this every tick.
that's kinda what i want.

[golden kite]

I ask this question, not sure whether this is the right channel: creating a dynamic NPC dialogue where you have different sequences for different sections of dialogue but you want them to blend seamlessly together. Is there a mechanism in Unreal that allows you to blend an entire animation sequence with another one at runtime? (the sequences consist of multiple actors, but always the exact same set of actors - ie: body, face and audio)

Our current method is to use interstitial montages between the sequences, but I'd like to be able to skip that since it's a bit unnatural

[silk cosmos]

There might be a setting in the cmc. I'm not sure. You could also just reset your vertical velocity before you jump, but at that point you're just doing the same thing as the launch character node

[hoary junco]

so I'm getting a weird issue where I've made a click and drag system for a physics object, but whenever I pick it up the camera goes screwy...
image 1 is viewport without picking it up
image 2 is with it picked up... the black bar at the bottom increases for some weird reason

if I run it in the standalone window the camera shifts to the right slightly...

and it doesn't just affect the camera view, while the object is picked up the mouse cursor is off to the side of where it's supposed to be

you can't see the mouse on the screenshots but the cursor was where the red mark is, when it's supposed to be lined up with the object it's picking up

[golden kite]

Well that's gotta be frustrating. I don't imagine you have the camera look-at targeting the object do you?

[hoary junco]

nope, the camera is just a static camera placed in the world set to be possessed by the player. The camera isn't meant to move in this level

[main lake]

Why does this code work at first then semhow it works twice even if I only pressed my "G" key once and because of that it keeps me in the GameSettings Menu instead of flip flopping, once I'm in that menu and once I'm in game. Also when in that "GameSettings" menu I have to press one of the buttons to be able to get my "G" key detected again (and it's where it calls the "Show / Hide Game Settings Menu" twice).

You can see in the top left it's being called twice even if in that menu I pressed "G" once

[golden kite]

When you attach a print node to the flip flop output do you see it toggle as expected?

[main lake]

The one before the flip flop in the screenshot ? Or you want me to put one for each flip flop output ?

[hoary junco]

each flip flop output

honestly I've stopped using flip flops because they give me so many issues XD

[golden kite]

I mean, you could probably recreate the flip flop functionality as a macro and then you'd have total control. But let's make sure it's the flip flop that's not working rather than something else

Your debug print should read true, false, true, false etc every time. If not the flip-flop has flopped.

[main lake]

@golden kite @hoary junco

• When I press it the first time, it prints A, so that's good > It opens the "GameSettings Menu" > so all good
• when I'm in the menu, pressing G doesn't print "B" so it's like it's not detected. > I have to click one of the picture to flip its state then my "G" key is being detected again but it calls the flip flop twice and I have A and B both printed

[golden kite]

I had something different in mind though - I was suggesting you run your print from the red boolean output of the flip flop.

[main lake]

The prints on the picture are all printed after 1 "G" key press (corresponding to the second press after the first one)

[golden kite]

It sounds like an event focus issue, but this is getting out of my comfort zone. My guess is that you have some kind of context in which the keypress is being listened to, but when you show the menu, then that context is lost so it's not even listening for the keypress at all...

[hoary junco]

for "set input mode UI only" try setting it to "set input mode game and UI"

[main lake]

what exactly a "context" ?

[keen fiber]

Created a character BP(found it odd that UE kinda just handles all the inputs for movement) but its not affected by gravity. I can fly in whatever direction

[main lake]

I don't want that as I don't want my player to be able to move, attack, etc... when he's in that menu

[hoary junco]

then disable player controller

[main lake]

how ?

[hoary junco]

hold on gonna open up one of my other projects

[hoary junco]

so where do you have this code sat? like is it on the player pawn?

[main lake]

which one ?

[hoary junco]

the show/hide game settings menu

[main lake]

In the BP_HUD which is the HUD class

[golden kite]

Does the HUD go away when you open the menu? then it wouldn't receive the keypress events I think...

(Or maybe the menu consumes the event and doesn't bubble it up to the HUD)

[hoary junco]

ok well what you can do is put in a "get player controller" and from that "disable input" as for the target actor put in a reference to the player and hook that up

[main lake]

huh ? how the HUD could go away ?

[hoary junco]

then put in an "enable input" for after you make the ui go away

[golden kite]

I dunno man it'syour code. Just trying to throw some ideas at you to help you debug your issue

[main lake]

If I'm not mistaking it creates an issue as it disables all inputs on the keyboard so I can't press the "G" key either 😬

[hoary junco]

it only disables the player controller, if you have other input interfaces or if you have the key press set from outside the playercontroller class it won't disable those

[main lake]

In my case that key is created through an Input Action

[main lake]

I'm just trying to understand because to me HUD is a class that handles UI stuff, so I'm not sure to understand when you say "Does the HUD go away" 🙂

[golden kite]

Oh, just a misunderstanding then. To me a "HUD" stands for "heads-up display" which is a kind of GUI that you see when in-game. But when the menu dialog comes up, I was wondering whether it either makes the HUD go away or maybe it steals the keyboard input (since it seems to be modal)

I think @hoary junco is probably a better resource here as I haven't done a ton with keyboard inputs

[main lake]

Oh then in the HUD class I add a WB_GameHUD which is a HUD to receive all the UIs, and if you're talking about that, then no I don't modify that as it also contains other UIs that I don't want to hide like my health "Hearts". So I only modify the visibility of the vertical box containing my GameSettings menu

[keen fiber]

welp I tried to get back into unreal and they added this new input system which is mad confusing so I give up

[hoary junco]

so another thing you could do is in the section where you define what each of your inputs does, like move and attack etc, you could have a boolean variable which says "IsEnabled" and a branch coming off the event with the variable hooked up to it
something like this

then in your UI work you can cast to the blueprint where you have this code and set the IsEnabled variable to false while it's open, then true again when it's closed

but don't add this for where you define what G does

so G can still be used freely but all other controls are disabled while the UI is open

[queen dagger]

so i got the ui to work @lofty rapids! thanks for the hint now i got this place where energy charges

how do i make this a charge per tick where i hold the key down and the energy charges

[golden kite]

For performance reasons, you might want to not do it on every tick, but instead use a timer - if the condition for adding an energy charge is true when the time fires, then add a certain amount of energy. This could be every 0.5 secs for example.

[keen fiber]

well I'm at a absolute loss why add movenment input does not move my pawn at all

[queen dagger]

have you selected the pawn as the controlled pawn in the game setting

so when key is pressed, time is counted and energy is added

[keen fiber]

yep

if I press WASD it will print out data but nothing happens

[main lake]

Tried "Disable Input" it doesn't work properly as I still can move

[hoary junco]

did you try the other method I told you about?

[main lake]

which one ?

[hoary junco]

#blueprint message

[queen dagger]

show the bluepritn

[main lake]

Not yet, but that one seems not the best in my opinion, there should be a better solution but I don't understand why it's so hard

[hoary junco]

because that's how code is, sometimes you have to take the long way around.

[silk cosmos]

Disable input takes in a pawn and a controller and stops input events from firing on that pawn how are you moving your player

[main lake]

I almost have a solution with this but there's an issue of widget focus I think.

• Like when I press G to open the menu, it opens it no problem. And without clicking on anything related to the UI of that menu and pressing G again it closes the menu and gives me back my character controls > All good.
• Now when I click on anything on the UI and Press "G" again it doesn't close the GameSettingsMenu even if it's calling the event Show / Hide Game Settings Menu twice > So not good > However if after clicking on the UI, I click on the left side where there's no UI (where the world is) and then pressing "G" it closes the Show / Hide Game Settings Menu and gives me back my controls

Do you know how to solve this "focus" issue please ?

[main lake]

I know but I'm not looking to disable all the inputs as I'm using "G" to open and close my menu. So using "Disable input" will disable my ability to press "G", so I found better which are "Set Ignore Look Input" and "Set Ignore Move Input"

[hoary junco]

it's 4:30 AM for me so if someone else is able to take over on this issue please do so.. didn't even get my own question answered...

[main lake]

Alright thanks for your help 🙂 What's your question ? 🙂

[hoary junco]

#blueprint message this issue I'm getting with a shifting camera whenever I click and drag an item

[frosty heron]

why would u have those black corners in the first place

are u playing sequencer or something?

[hoary junco]

no.. that's just how it looks in the viewport

[frosty heron]

hmm not sure, I don't even know how to get those black corners to appear

[hoary junco]

I think it's to do with the resolution of the camera actor. Like the camera is operating in 1080p but the viewport window isn't at 1080p because of the side stuff

that said I still don't understand why it shifts off to the side when I pick something up

[hoary junco]

so I found out what the issue was after hammering away at it, got rid of both the black bars and the camera movement issue

"constrain aspect ratio" if I have that turned off then it stops the issues

it was on by default, not sure why

[frosty heron]

Ye I know that one but afaik seen when you posses a camera

The default camera from templates r fine

Hence why I asked if u r playing a sequence

[main lake]

Do you have a solution for my problem too please ? 🙂

[frosty heron]

Set input mode to UI only maybe

Why do u want the player input to work

When they are in inventory

[main lake]

Nope as that disable keyboard inputs and i don't want that

[main lake]

Because I want to open and close my menu with a keyboard keybind

[frosty heron]

That will disable keyboard inputs in your player character or controller

Not for Ui

[main lake]

I know but it will disable "G" when I'm in the UI so I can't press it back to close it again as it will be disabled as it's not part of the UI

[frosty heron]

U can have UI listen to G

[main lake]

how ?

[frosty heron]

Or w.e keyboard input

Either thru on key down event or listen for input action

[main lake]

Already tried that but it's calling the Show / Hide Game Settings Menu event twice for some reason

[frosty heron]

No idea how what you have on your end

I would suggest debugging

In my old project I just disable moving / attacking with a macro

It just takes a series of boolean

[main lake]

Already tried debugging for hours still can't figure out this issue, the last issue I had which is close to the solution is a "focus" issue

[frosty heron]

Is in cinematic? Or is in inventory or is interacting etc etc

When inventory open, look input will be disabled

Movement etc can be restricted with a boolean

[main lake]

I succeeded stopping movement already now I'm stuck with this focus issue

[frosty heron]

What focus issue

[golden kite]

To me this really sounds like either a focus issue or a state-based problem. And, for what it's worth, state-based issues are the WORST to debug.

[main lake]

#blueprint message

[golden kite]

You should really try to isolate the issue and figure out which of the two it is.

[main lake]

what do you mean by "state-based issues" ?

[frosty heron]

I don't know about your project

If u have multiple widgets, how I do it is, on widget hover, set focus

Call it a day

[golden kite]

If it's a focus issue, it means that the BP you want to receive the keypress event isn't getting it, and so the event will never fire. If it's a state-based issue it means that you have some logic that is different depending on what state the game is (ie: menu open or menu closed)

[main lake]

It's the definitly the first sentence

[sage lagoon]

When it comes to widgets, how do I set a keyboard or controller button to work instead of having to click on buttons?

[gentle urchin]

Then figure out which one does recieve focus

Widget reflector ?

[sage lagoon]

Widget reflector? I don't think I've heard of that, but let's see...

[frosty heron]

You can detect keyboard input with On Key Down

you have to write your own logic for the rest of the stuff

[main lake]

How does it work ?

[frosty heron]

I wouldn't personally bother adding controller support

[gentle urchin]

Read about it @ Diversity

[frosty heron]

or keyboard support for selecting button

its not hard, i can totally do it caveman style

but not worth the time

[sage lagoon]

So this isn't something I can configure with nodes?

[gentle urchin]

Cavemanstyle allows for node based approach atleast

(Atleast the cave style i used)

But its frowned upon I guess

[main lake]

Check something called "CommonUI" that's what Epic uses for Fortnite

[sage lagoon]

Like here?
https://docs.unrealengine.com/5.2/en-US/input-fundamentals-for-commonui-in-unreal-engine/

@main lake

[main lake]

Yes, I suggest you watching youtube tutorials (Unreal made a long stream of more than 2hours about that)

[main lake]

This one receives focus

[sage lagoon]

I'm going to sound stupid again, but what do you mean by Caveman style?

[gentle urchin]

This should guide you.

Pie window getting focus means nothing else is gwtting it

Extend widget name, compare to expected

[main lake]

I'm not sure to understand 🤔

[sage lagoon]

Extend widget name?

[gentle urchin]

Thats part of the development ^ learn, test, verify, twindle in darkness.

[frosty heron]

https://tenor.com/view/debug-deploy-debug-gif-13992197

[gentle urchin]

Theres 2 convos going on here at the same time, extwnding widget name in the reflector is to help Diversity see where the focus is going and where its not

[sage lagoon]

Print strings are your best friends when it comes to debugging. And okay, I was confused.

[frosty heron]

not really

there are arrays of tools one need to use

[gentle urchin]

Print string > bp debugger

Imho 😄

[sage lagoon]

Well...for testing, anyway.

[main lake]

I will go to sleep to debug my brain first, then I will see the rest later 👀

[gentle urchin]

Basically not according to standards and what we're expected to use for this

Theres built in systems for handling moving between and in widgets

[sage lagoon]

It occurred to me that I could put in a Press Enter node, though the controls are disabled. I wouldn't want the player to move around when he's not supposed to, anyway.

Disabled during cutscenes, I mean.

[gentle urchin]

But they are at times clunky, so doing caveman style simplifies it alot

[queen dagger]

what node do i add to create ticks while the button 6 is pressed down

[sage lagoon]

Any explanations or pages or the like on that?

[queen dagger]

so far it just ticks one when pressed

[gentle urchin]

Enable tick / Gate / branch

[queen dagger]

ok ok

[gentle urchin]

Set timer is an option

[gentle urchin]

Sadly no

So its even more in the dark

[sage lagoon]

Just like me, I'm afraid.

[gentle urchin]

I used a bunch of listenforinput

Set to consume

Then i had a parent widget of focusable type, and one container parent

Which allowed me to gate all inputs at any point

Being very explicit about what this or that does when a certain element is in focus

[queen dagger]

@gentle urchin

how do i alter the tick rate

[gentle urchin]

Set actor tick rate?

Id just use a timer at that point

This isnt ticking btw. I just mentioned the options you had

[queen dagger]

oh

lol

im not really too good at blueprints yet

[sage lagoon]

What if I put in a Pressed keyboard key input that enables input for only a second then disables input all over again?

Though the keyboard keys would have to be enabled first, and they are disabled during widget dialogue scenes. So that won't work.

[ionic quiver]

I can't find anything on this on google, probably cause it's either stupidly easy and I'm being dumb, or stupidly complicated. lol
I'm using Orient Rotation to Movement for my character, but I want to still orient him when he can't move. I have the branch all working to stop him and check for it, but how do I set the actor rotation based on WASD input?

I'm guessing I need to create my own setup for it at this point

It's use controller rotation roll isn't it...

99% of the time after I finish asking something I figure it out. God darn it lol

[queen dagger]

what timer would i use and how @gentle urchin

[ionic quiver]

Create Timer by Event. You can set it to loop and specify how fast you want it to execute

Then hook up the event to it

Have it run on Event Begin Play

If you want it to always trigger

Or E if only during press

Then on release clear and invalidate that timer

[dim halo]

I am trying to make a level where the player must create floors and navigate through the level by their creations, but I want enemies to be able to fly around, as it seems increasingly complicated to do so using a pathfinding system, would it be possible to work around this by creating a floor thats invisible and somehow coding it so that only specified entites can walk on it or is that not possible, and so the player would slip through it and enemies wouldnt?

[ionic quiver]

Or, if you just want it to run while being held down. Use the advanced input actions, they have hold functionality built in

[queen dagger]

ohhhhh

[ionic quiver]

So you can do that. You would do it by creating custom object channels and having those characters / floor block only each other, and everything else ignore. It's under Engine > Collision. But probably figuring out the flying would be more advised.

[queen dagger]

ok so i used the advacned input action is there any way i could posibly slow it dow now

[ionic quiver]

It's all in how you configer it

I recommend watching a youtube video on it. It can get pretty advanced based on what you need

There are tons on Advanced Input too since everyone has transitioned to it after 5.1 🙂

[queen dagger]

ok dope thanks for the tips man!

[ionic quiver]

I was wrong. It only worked while I was on the ground. Darn it! Still need to figure it out I guess.

[dim halo]

I think for the flying portion I would likely just make the creatures have a invisbile compnent to their character that is very tall and than situate the actual design higher in the air, thus simulating flying while actaully just being on the ground

[queen dagger]

i figured it out it was so much simplier than what i was thinking just set a delay for the action input

i feel so dumb lol

[gentle urchin]

We've (mostly) all been there lol

[ionic quiver]

It's past my bedtime and it's ugly.... but it works lol. I'll figure out a smarter / cleaner way in the morning. But prototype is a success. 🙂

[gentle urchin]

Youd want nearly equal 0

[ionic quiver]

That wouldn't work for me if that's what you're referring to

[gentle urchin]

Its a float,

You generally cant rely on total equalness

Theres also an easier way to do this

Increment = (1 x up)+(3 x Right)

-2 | 1 | 4
-3 | 0 | 3
-4 | -1 | 2

Just make sure you ceil them, and add any deadzone to it

Down left is -4, upright is +4
Add 4 to the result to shift it to 0 to 8 range

Not exactly right, just almost

Fixed

[heavy plinth]

Hey guys I have a really difficult problem. I'm trying to figure out to make a one-way door (like a shortcut/door that leads back around) using these physics doors I've created. I also have a lock and key system already setup

Here's my code

[limber parcel]

just make a trigger box on only 1 side of the door

[heavy plinth]

What would I do with the trigger box though? That's the part that confuses me

I'm actually alreaady using a trigger box so should I just move it to one side?

[limber parcel]

that depends on what exactly you want to do with the door

you could use the trigger box to open the door, or to close it behind you

and to lock it

[harsh coral]

Heya,
quick question:
I´ve got a pretty heavy construction script and I added a few switches to turn on visibility/hidden in game for a lot of elements, so I can control them via sequencer.
It works fine in the editor, but as soon as I create a sequence and add the blueprint to it to override these settings, it no longer updates, neither in editor nor in PIE, no matter if teh switches are animated or not.
Any idea on where to start troubleshooting?
I got no events set in the event graph, just the construction script.
These are the tick settings:

[vast finch]

Good evening. Apologies if I don't reply for about a day. I'm having issues with this line trace not returning the location. In the first screenshot, you can see it's returning 0,0,0
The purpose of this is to get a vector to align the AI's muzzle to their target actor through a blend space in the anim blueprint.

[harsh coral]

I mean, generally I probably do not want to update the sequence on every tick, as there are 300+skeletal meshes in there.
But at least everytime I play the sequence, it should update the animated values.

[harsh coral]

Is there a simple way to do this, without having to create a specific function called "update" or something, that updates ALL animatable variables, just so I can see the changes in editor directly?

[main lake]

When closing my menu, I can move again (so that's good) however, I can't look around and have to left click 1 time to gain control of my camera, how to solve that please ?

Same issue when I launch a session

[timber crystal]

Quick question: Is there a way to fix the background images in a 2D game so that they always move with the camera?

[limber parcel]

by attaching it to your camera

[uncut seal]

i want to make a system like wrecking ball's grapple hook (overwatch), this is what I have so far...i need some help trying to make the actor swing, like some sort of way to make a limit on the grapples distance, or something?

[limber citrus]

is there anyway to write into a data table from blueprint?

maybe not a data table but something else that can be exported as a csv, not sure if it's doable

[mild jacinth]

Is it possible to somehow assign a specific player controller to a pawn that is being spawned, using "SpawnActor' node?

For an example I dont want to spawn a player using Player Start or Network start. I just want to spawn the actor BP itself and use 'possess' node. But as I understand it gets a totally random playercontroller, am I correct?

[frosty heron]

what makes u think it gets a random player controller?

for single player games, you just need 1 controller anyway

so get player controller 0 is fine

[mild jacinth]

Im using acf framework and acf has a pc called fullacfplayercontroller. It has some combat targeting component attached to its own pc. I am unable to use combat targeting which makes me think its the custom spawnactor nodes, because in running spawning logic from persistentmap

[frosty heron]

is that a plugin? it probably is, so no idea

can't tell what other people are doing with their codes

but going back to the controller

for single player anyway

get player controller 0 is fine

there will only be 1 controller in the world at all time

[mild jacinth]

Its an unreal engine asset framework used for creating rpg games, but i think its not getting the right pc. It would make sense because keybinds for that function are also there

I need to get specific class of pc and it would work only through player start i think?

[frosty heron]

is this sing;e player or multiplayer?

[mild jacinth]

Why is it not possible via bp?

Single

[frosty heron]

there is only one controller

just get player controller 0

https://www.unrealengine.com/marketplace/en-US/product/ascent-combat-framework-c-action-rpg-creator?sessionInvalidated=true
Your best bet is probably to join their discord channel or ask the authour

no one can tell what's going on without having access to the code

[mild jacinth]

Okay but what class of pc is it? There are tons of different types. I can print debug text and see what class it is tho

[frosty heron]

Get Player controller -> Print string

[mild jacinth]

Yes thats what im getting at. Its not related to acf. I just want to know if i can assign a specific pc when i am spawning player manually using spawnactor BP and possess nodes

[frosty heron]

the player controller assigned thru game mode

[mild jacinth]

Like gamemodes have their owb pc assigned

[frosty heron]

and that will be your pc

[mild jacinth]

So gamemode assigned in world settings is responsible for the correct PC, even when spawning manually using blueprint nodes?

[frosty heron]

you are assigned the player controller that you set from your game mode world setting even before you have a pawn

[mild jacinth]

One second

[frosty heron]

So all you have to do here for custom spawn, is to override the game mode the function that spawn your player, so you don't spawn thru game mode

then do your own spawn logic

and just possess

call it a day

[limber parcel]

unreal has thing called constraints

[frosty heron]

You are not spawning any controller btw, you are spawning a character/pawn which you posses with your controller

[uncut seal]

i was looking at constraints but im not sure how I could make my component 1 the correct location, im just sending a raycast to hit anywhere in the world, so yea

[mild jacinth]

I got the class display name and printed it out. It is the correct one. Issue is elsewhere, thanks for info btw!

Looks like gamemode takes care of it even when manually spawning

[frosty heron]

wdym by manually spawning tho >_>

controller is created for u by the game mode at the start of the game

it happend behind the scene

Wether u spawn character/pawn ur self or not, doesn;t matter

that's a completly seperate action

you can spawn nothing in the world and still have a controller

[limber parcel]

idk how exactly constraints work in unreal, but u will probably want it to hang from some sort of ball socket

[uncut seal]

i'm going to try placing an empty object at the raycast hit, and swing from that

[paper scroll]

Am i missing something?

[limber parcel]

https://tenor.com/view/kane-tiberium-gif-22119534

guess u cant make an array of that structs?

[frosty heron]

@paper scroll looks like you modified your struct

I do pray it's not a bp struct

[timber crystal]

ok thanks i try it out

[storm stream]

Hello, noob here. I have a question with memory size map and widgets. My component has hard reference of UI widget (inventory), where is located preview of main character whats takes around 1 GB of memory. I dont want to commit it to memory on game start (component is attached to main character, so is loaded after start). Can find solution for my problem, but its still have some issues. If i make my hard reference UI as soft reference and then loaded before creating widget then is almost work, the issue is that takes around 1-2s for loaded and its a bad thing but only for frist one, later its open instant (so its still will be loaded infinitly in memory? how its works?). So i thoung about loading it on game start, but now i wonder if its a good thing? Summary in both ways my inventory still is loaded on start in memory, but now as soft reference. The only difference is that, my memory map is clean in Unreal (200 KB instead of 2 GB Im thinks in right way?) Now my question is, if i use soft reference and loaded in on game start, it will be diffrent than making hard reference of creating widget? It has other issues like, after some time it will be removed from memory and i will not be able to open UI? or u guys have other solusion of my problem?

[spark steppe]

make a hard reference if you load it anyways

there's no point in a soft reference in that case

[storm stream]

some ppl on general speaks its make difference

[spark steppe]

that's a weak argument

[storm stream]

Hmm so thats size memory shows 200 KB instead of 2 GB its just unreal bug? like its dont bring soft ref intro summary?

1 gb*

[spark steppe]

that's not a bug

[storm stream]

so whats the difference between this?

[spark steppe]

a soft reference isn't taken into account, unreal doesn't care if you load it

[storm stream]

oh

[spark steppe]

you use soft refs for stuff which you MAY load, not for stuff that you load 100%

[storm stream]

i dont want to load it on start, but it is on component whats attached to main character, how i can do it in right way?

[spark steppe]

so you expect to have game runs where the player doesn't open their inventory?

[storm stream]

so is no solusion for this? i need load another 1 GB of memory?

[undone bluff]

why stop the player from playing the game because of the inventory when they're likely not going to open it immediately after initialization?

[versed sun]

Hard Ref load the UI, but Soft Ref all the Textures/Meshes that arnt being used immediately

Big chunk of transparent beards and such

[undone bluff]

I hard ref the HUD, but soft ref openable menus

[storm stream]

in my case i loading full character intro UI (character preview)

[spark steppe]

having an 1GB footprint widget is your main problem

[storm stream]

Yep, but 99 % of it is character 3d widget with construction actor

[undone bluff]

you can always soft ref just that

[storm stream]

and this is my UI widget

[storm stream]

i thoung about it

but in case if another widget like skills or so has another additional MB with it becouse of images, how i can avoid this? Make HUB (Main tameplate) and loading the rest of with soft reference?

hmm i think its works. Thanks guys for explain ❤️

[white oxide]

Why does my line trace by channel only apply for the first frame on event tick?

[gentle urchin]

It doesnt

Unless you gate it somehow

[storm stream]

or block it with branch ;P

[gentle urchin]

(Thats the gate part)

[storm stream]

xD good to know

[spark steppe]

he asked why

not sure what is meant by first frame of the tick tho

tick happens every frame

[gentle urchin]

He asked why, indeed. And showed a pic of that single node, providing zero context beyond "Event tick" at all 😅 not sure what answer to expect from that

But you're right, tick hapoens every frame, so eother there's a flow gate here, or we need more context

[frosty heron]

can only make educated guess at this point

🦦

[gentle urchin]

My funnyness doesnt always sparkle through my answers

[frosty heron]

ur trace probably works every frame

[frosty heron]

unless u kill the object

draw debug and look at the trace

[versed sun]

Maybe because it lasts 5 seconds and doesn't move ?

[white oxide]

did that only draws once

[frosty heron]

I doubt it

set draw mode to presistence

then ove around

[white oxide]

Tried that too

[frosty heron]

send video

or just print string before / after the line trace

if you never move the points, then you wouldnt be able to visually clarify

[versed sun]

is Sphere Collision moving ? is Trace Distance set ?

[white oxide]

The distance output is the same even when I move

or jump

[frosty heron]

that doesnt say much, send a video

draw debug for duration

set it to 5 seconds

[frosty heron]

if it never dissapear then it always work

[white oxide]

Picture says a thousand words

[frosty heron]

there u go, it gets called every frame

u are just not able to clarify visually because the start and end point never change

[white oxide]

But it's only drawing for the first frame

[frosty heron]

its drawing every frame

but drawing at the same location is my guess

[white oxide]

Yes it is.

[frosty heron]

hence how can u tell if it's drawing multiple times?

I don't know what yes is in this context

[versed sun]

Print out your End Vector

see if that changes

[white oxide]

No dice

[frosty heron]

so it's confirmed at least

that the trace is drawn every frame

not just first time

[versed sun]

where is collision sphere ?

[frosty heron]

you just never change the location

[white oxide]

The sphere collision is never moving

[versed sun]

do you want it to move ?

If you want line trace to be based of the spheres Location and rotation, and you dont move the sphere , then the linetrace wont change

[frosty heron]

im gonna make another educated guess with the limited info

the sphere (not the sphere collision) is transformed with local transform

you can play in Pie, move around, eject then select the comp, if the sphere actor transform remain unchanged, then that's the problem

[winged totem]

Hi, i'm using this material node "PerInstanceRandom" and works fine in pc but not android.

It says The output value will be a whole number between 0 and RAND_MAX for the target platform.

How can i set that value for android?

[spark steppe]

are you sure that primitive data is support at all on android?

may also depend on the shader platform you target (vulkan will more likely support it)

[neon acorn]

Hey all, can someone help me in understanding what exactly deactivating an actor component does? I thought deactivating the component would get the events to stop firing but it doesn't. Then what is the purpose of deactivating the component??

[spark steppe]

you can disable the tick for the component, which will often yield the result that you expect

[neon acorn]

I know about disabling the tick and it does get the tick event to stop firing but not other events

[spark steppe]

there's no ground truth for activate/deactive, actor components can implement those events to do their own logic

[neon acorn]

In my actor, I am binding to the mouse click event in the beginplay for eg,

[spark steppe]

do you mean event's firing for the component, or event's firing which the component subscribed to?

[neon acorn]

events firing that the component subscribed to, like the mouse click

[spark steppe]

yea i don't think that there is ANY way to disable this

[neon acorn]

ah! So I will just listen to the component activation/deactivation events and handle the event bindings there

[spark steppe]

because the event system just knows, in case of an event, fire this method on this object instance

you would need to add your own logic in activated/deactivated to subscribe/unsubscribe to the events

[neon acorn]

yeah, thats what I was thinking of as a "workaround" but I guess thats how things are supposed to be?

[spark steppe]

supposed is a strong term in that regard 😄

i guess it's rather that's whats given by the event system

it isn't aware of the fact that components could be deactivated

it doesn't even really care if the function it calls is on an actor or component or whatever

[neon acorn]

hmm...so there is no primary purpose for function activation state...its what we make of it

Maybe there is some performance advantage over keeping unnecessary components activated

[spark steppe]

some actor components may have logic there

[atomic salmon]

At Actor Component level it is a virtual method. Some actors like Niagara Systems use it to decide whether they should produce a visual output or not, independently from the fact they are ticking

Handy for performance intensive actors which can still tick but not produce any output

[neon acorn]

Gotcha! So its there as a nice utility for child components. I think implementing it is exactly what I need

[sonic pier]

Why is navigation invokers not working when i spawn an actor with navigation invoker

[brisk marsh]

Hey guys, I'm new here. I have this one big question. Any help will be highly appreciated. I am trying to make a grappling hook like in Just Cause 3. What should I consider when making one, and how can I do it? Is there any physics involved? Thank you.

[hallow compass]

has anyone looked into the performance implications of animating a static mesh by using timelines , vs making a super simple rig for it? I need to make a bunch of simple reusable animations for static meshes in a game (chests, mechanical elements, etc) and it would be great if there was something like animation clips in unity, but that doesnt seem to be the case. There are level sequences, but they cannot be assigned to actor instances, as far i know. So I either use a bunch of timelines, lerps, or just rig it, but in that case i lose the nanite benefits. Any suggestions?

[spark steppe]

you don't lose the nanite benefits

you make a skeletal mesh with a plane as geometry which you hide, then you attach your static meshes to the bones

[hallow compass]

as a start, you could just trace to the grappling location, and shoot a projectile to it. when the projectile lands, you lerp your character's position from where they are until the grapple location. Once you get that going you can think about physics and other cosmetics

[hallow compass]

oh thats genius

how did i not think of that

[spark steppe]

that's what epic does with cars and what they did in their nanite trailer

[hallow compass]

thank you so much!!!

[brisk marsh]

Alright I'll try that and see what I can do.

[white oxide]

I'm having a problem with line trace rotating with the up vector of the sphere that I am moving and I want it to shoot straight down. Not be relative to the rotation of the pawn... any thoughts?

[spark steppe]

yea ignore the rotation

world location as start and world location - 0, 0, 100 or smth as end

[hoary junco]

is there a way to create a state where an object acts like it's on a spring? Like whenever you pick it up it tries to return to a pre-defined rotation? I'm not lookin for a rotation lock because I still want it to be able to rotate, but whenever a force has stopped being applied I want it to spring back to its default position

kinda like those double doors you see in hospitals that close by themselves

[white oxide]

Perfect. Thank you!

[pallid sphinx]

ive got bits of gear and their stat bonuses are being managed by two structures called WeaponInfo and ArmourInfo the weapon one is working fine when i try to use it to influence player damage but the armour one is always spitting out 0 and i have no idea why

[hoary junco]

where is it pulling the data from?

like can I see more about where the Armour Info stats are stored?

[pallid sphinx]

its pulling from a Structure

[hoary junco]

Can I see it? First thing you need to look into is the source, like is the structure where you hold the stats feeding a value into the proper place to grant it an attack bonus to begin with?

[hoary junco]

you're pulling the info from BP_BaseArmour not BP_Top, is BP_BaseArmour have the same attack bonus as BP_Top?
