Drag off the target's reference pin and search the same thing, that's what I've done in the past.

[prime fulcrum]

What target reference pin? (Sorry im quite new)

[spark steppe]

in your 2nd pic the variable will be set on the current actor/bp, if you want to set it on another actor you have to drag from a reference to the actor (your actor variable for example) and search for the variable

or most likely from the streaming level reference of the node before the return node

[prime fulcrum]

i don't understand

[spark steppe]

drag from the blue pin of your get streaming level node

and search for the variable

[twilit jacinth]

Working on a twin stick style 3d game. Seems like everything is working for now bur the right thumbstick on controller doesnt register at all. Can someone look into a mess I did and point out where I could be wrong?

[prime fulcrum]

Like this?

[spark steppe]

yes

[prime fulcrum]

Thank you!!!

[spark steppe]

if you want to set the variable on the streaming level...

[prime fulcrum]

yeah i have the same as the tutorial so it should be good xD

[prime fulcrum]

@spark steppe

The tutorial guy has this icon

I have this

does that mean something?

[spark steppe]

ask the tutorial guy?!

[wooden ravine]

how to make an object moving along a spline (or other path) in an constant speed, no matter how long the spline is?

[prime fulcrum]

fixed it but 1 more thing...

how can i remove that thing

i don't have acces anymore

to those things

[wooden ravine]

i looked at a few tutorials however it's always with time to complete with the timeline, i need the speed to be same however (working on a starfox clone)

[gentle urchin]

Drag a window over it, then cancel that drag, its a bug :)

[restive token]

how are these camera movements done?

Thanks

[restive token]

it's not sequencer right?

is it multiple "view target with blend" things?

[cobalt gulch]

Is this how you would show the local player's health when on a server?

Because i'm updating the health when the bullet hits a player and it damages them, but it doesnt actually show on the hud

[flat coral]

Am I missing any setup steps for AIPerception? I've got it on one pawn and I've got AIPerceptionStimuliSource on my player pawn, both set to sight, but the pictured breakpoint never gets called even when it's directly beside me

[trim matrix]

is it possible to create a new dynamic playerstart from a bp actor?

my level is generated procedurally and i cant set the playerstart before runtime

[flat coral]

This was the problem. But how do pawns get classified as friends or enemies? Is there a whole allegiance system I dontk now about?

[trim matrix]

so should i have to change the world location of the player start? i tried with set world transform node but it ask for "In Element handle" and i don't have it

[flat coral]

Unfortunate.

Ah well, for now I don't need any check more complicated than casting to player pawn

I could roll my own version of an allegiance system easily enough. Probably just have a super basic ActorComponent called AllegianceProvider which just stores and returns the allegiance of any pawn, and then the code on the AI perception event can discard detections if the allegiance matches

[ocean arch]

Is there a way to check if the game is in standalone mode or PIE with blueprints?

[flat coral]

If UE invented the wheel, but only for C++, reinventing it for Blueprints seems like a logical next step

Hi guys, I am trying to decode a byte array in utf-8 method using low-entry extended standard library and it's not working in iOS so is there any other methods to do this or are there any other plugins for doing the same?

[exotic vault]

Can you help me?

Hud warzone namely with 3 armor

[thin panther]

drag some pictures onto a hud ez

[jaunty jolt]

Why is C++ code faster than Blueprints? Aren't blueprints getting translated as C++ code after compilation? Isn't it possible that im so bad at C++ that my blueprints are actually faster ?

[thin panther]

blueprints do not get translated to c++, they get interpreted in a virtual machine, rather than c++ that compiles down to assembly instructions and machine code, which can be significantly faster

[exotic vault]

I understand this, but I often have a problem that the hud armor does not work

[thin panther]

and no not really to your second point, obviously a blueprint function that just adds two numbers together may be faster than an entire c++ subsystem, but if theyre doing the same thing c++ will always be faster

sometimes c++ means the difference between compiling and not compiling

in bp a for loop with 1000 elements won't compile, but in c++ not only does it compile, but it also runs in like a millisecond

my favourite way to do things is to write functions in c++ that i can use in bp

[gentle urchin]

^ this

[exotic vault]

is there any way to recreate 3 armor bar?

[thin panther]

that way you still get the bonus of rapid prototyping, but also the speed of c++ code, sure it is a little slower than pure c++ but marginally

[thin panther]

several ways, progress bar, 3 separate images etc

[jaunty jolt]

I see i will have to bite the bullet and learn c++ properly for ue. is just that the c++ tutorials i have seen look so abstract and intimidating. im a very visual person, so i love blueprints.
so for example. a loop of 500 in c++ executes in 1 milisecond. what about in blueprints?

[thin panther]

in bp it probably wont let you compile

[exotic vault]

I have made separate images, but nothing decreases or increases, but it seems that I did everything right

[thin panther]

i will admit the tutorials are intimidating, learn a bit of regular c++ first, just start with how to do basic stuff, learn about pointers, then have a look at unreal

unreal c++ is very intimidating as few other languages let you have pointers

so theres a lot of weird things you will have never heard of with say python

then once you start getting the hang of c++ a bit, the logic is the same as bp, you just write it differently

epic even has a guide on translating bp to c++ i think

you still get all the same stuff, you just get even more of it

[flat mauve]

precisely

[tawdry surge]

@jaunty jolt You can absolutely write bad code and make it run worse then BP

[thin panther]

oh yeah definitely but thats just part of learning

but again some stuff you cannot avoid it for

[flat mauve]

You learning c++ @jaunty jolt ? Sweet! I'm on a journey to step up my coding mojo as well!! If you want, we can psyche each other up and keep each other accountable! I found some great tutorials recently 🙂

Hey guys! I'm having some bit of trouble

[thin panther]

w3schools is a great resource for the basics of c++

i find it explains things really well

make a few simple console apps and then look at stepping up a bit

i did some basic console apps then went to learning sfml once i understood pointerss

[spark steppe]

So this sequence node is excecuting backwards for me. Starting from the bottom instead of the top! Any idea on what's going on? How can i fix that?

[spark steppe]

it does not

you are probably confused by the order of print statements, aren't you?

[flat mauve]

Yeah for sure!!!

Print statements are executing backwards

Does it only work that way for print statements?

[spark steppe]

it's the way the buffer works

but they aren't executed backwards

[flat mauve]

So if i compile a game for instance, will the order become "corrected"?

[spark steppe]

no

the game runs backwards

it's just that new stuff gets added on top of the print buffer, just deal with it

print statements aren't in packaged build anyways

[flat mauve]

I see. So this works for print statements only?

[spark steppe]

read the output log if you want them in correct order

[flat mauve]

I see. So i kinda have to think backwards to make it look like it's working forwards?

[spark steppe]

no

[gentle urchin]

The print list goes from bottom to top

[spark steppe]

you have to scrap the idea that print statements are a good way to follow execution flow

use the output log instead

[gentle urchin]

Later prints are 'injected'

Or stacked

On top of existing

[thin panther]

wait so its LIFO?

[gentle urchin]

So if you do a print on tick that lasts beyond 0.0sec you can see the 'oldest' data being pushed downwards as new prints are added

I wouldnt say its LIFO, no

cant find anything under format in bps whats it called ?

[gentle urchin]

Format text

Is the node

Reverse it from the return value

Write what i told you

In the format text node

Unplug the texts, and type it in

[untold zodiac]

what am I doing wrong to make this replicate on server? This bp is for door opening

[desert juniper]

what i do is just replicate (repnotify) a DoorOpen bool

[wraith crane]

can someone tell me why this not working? parameter name is good and the timer working but this not setting the param to 0. I have to put something in creation flags?

[desert juniper]

then have the timelines play on the client. this way, the server isn't replicating the door angle on tick

[untold zodiac]

Im familiar with the rep notify, but could you show me an example? I am very new and would be very grateful

@desert juniper

[desert juniper]

don't have unreal open atm, but jsut make an event to open/close door. Then just call it in the OnRep_IsOpen (bool variable you set to OnRep Notify)

When the event is called, just play your timeline for animating the out with all your logic.

I can share what I have tonight if you ping me in about ~7 hours @untold zodiac

[gentle urchin]

you need to assign the material to something

[wraith crane]

i assign the material to the floor

[gentle urchin]

not in the bp you showed me, you're not

[wraith crane]

oh

but

how to assign this instance

[wraith crane]

not the orginal mat

okay thanks

[gentle urchin]

set Material

[wraith crane]

can i get all objects with the orginal material?

[gentle urchin]

You could make a lookup function for it i guess

[wraith crane]

i dont know how but i try to check on youtube

[untold zodiac]

I definitley will @desert juniper , is the custom event Im creating with the open/ close logic ran on server?

[desert juniper]

doesn't have to be marked as such.
because it's being called from the OnRep function, it's automatically going to be ran on the server.

[faint pasture]

#audio but have you tried lowering the 3d stereo spread?

[young stratus]

Hello there to anyone who has knowledge about unreal physics, I seem to be a bit stuck with my scalable cube. The moment I scale it between 2 walls it will receive massive impulses and just fly around everywhere. Any way to prevent this from happening? The collision detection seems to trigger later than the actual resolution.

[faint pasture]

What do you expect it to do as it grows and begins colliding?

[young stratus]

I set up some blueprint code that prevents any further grow, the issue is that it already gets impulses before that actual hit gets detected

[drifting peak]

@young stratus can you send screenshot of sample

[young stratus]

it seems I have found another solution, (BoxTraceByChannel) and it seems like it will do the job, but thank you

[drifting peak]

good to hear 🙂

how do you set a relative path of the Model 3D folder?

you shouldn't have spaces in your paths either ways

Hey @toxic jay have you done this before?

yeah.

Thanks for the #cpp object reference. Pun intended

[cyan birch]

... You're being asked to move the conversation to a more relevant channel. Us BP users are scared.

[balmy apex]

Alright, so, I have this bit of Blueprint set up, but the pitch (I think) is inverted. I move the mouse up and the camera looks down. I don't want that to happen, but I don't know how to fix it.

[flat coral]

Is there a way to have an event or something for when a blueprint variable's value changes? I wanna it to be automatically synchronized with a value in a Blackboard

[flat mauve]

Hmm... I see. In your opinion, why are books/articles better?

Hahaha!

[balmy apex]

Bless, this is how I did it. I better knew how to do the multiply than the input settings thing. Just switched over to UE5 so I'm a touch lost.

[cyan bone]

Why is my collision not stopping my character? This is a procedural mesh collision generated in the construction script.
The print "collision working 1" is printing correctly. But then it doesnt stop the character. So strange.

[drifting peak]

@cyan bone is your procedural mesh changing in run time?

[cyan birch]

I'm not super familiar with procedural meshes, but why is it set up like this instead of just having the collision block pawns?

[drifting peak]

or it doesn't change or move after execution

[cyan bone]

No. I just generate it in the construction script. The thing is it prints the message, so why it doesnt stop movement? It does stop movement in other collision. So strange

[drifting peak]

are you trying to overlap the ArmyPlanes Class?

[cyan bone]

Yes. and thats happening because its printing the message

However it is not doing the Stop Movement i dont know why

[drifting peak]

if you want to check for ArmyPlanes, you dont need your double branch before that

those two booleans arent needed

[cyan birch]

Is this in your character BP? It looks like you have no way of telling this script what character movement you want it to stop.

[drifting peak]

you just need to cast to your armyplanes class and it will only read that class

[marsh bramble]

trying to get player character to attach to horse without possess everything is working except he doesnot go into saddle he kinda stands under horse https://gyazo.com/26a481785178badbb1c1d2eecb5fd9b8

https://gyazo.com/c82ea04ec6b2648f3ec9177fc66b8a31

[cyan bone]

It is my character BP. And its working if it is on another Collision. The stop movement is working. Its just not working when it comes from a procedural mesh collision.

[drifting peak]

@cyan bone cast to your army class, then drag out blue pin, get character movement then stop all movement immediately

[cyan birch]

You are attaching the actor's anchor to the anchor of the other actor, so you'll need to adjust the location to get him to sit correctly.

[cyan bone]

But i want to stop my Character not the target character that is overlapping me?

well actually that works in this situation, because they are the same type.

[drifting peak]

do you have an invalid return from the cast?

[cyan bone]

but you see? why is it not stopping my character? its ignoring those 2 nodes, yet i know they are right because they work in the othe collision

[drifting peak]

do you get a red message after overlap?

[cyan bone]

No. Its printing the print right after it.

[cyan bone]

No. No red message

[drifting peak]

can you send screenshot of the components

and a screenshot of the construction strip if you are generating the mesh at play

[lapis shale]

Hi! I'm a bit new to unreal engine and trying to learn. I'm trying to animate a model based on if it's walking or idle. I set up a simple state machine based on an "IsWalking" variable. For some reason it doesn't seem to work. The animation seems to be stuck in the Idle state. Whenever I adjust the variable manually it does work, so my state machine is fine. Is there anyone who could help me out?

I suspect something's going wrong here because I don't really understand what's happening here, i got it from a youtube tutorial.

it's the event graph of my animation blueprint

[drifting peak]

@lapis shale connect it

[marsh bramble]

@cyan birch yes i attempted to do this earlier and i did it wrong it shot my character off the map

[young stratus]

whenever you see the play symbol on a node you want to make sure execution can flow

it's kinda like a telephone line, if you don't connect the electricity it won't work

[lapis shale]

It's all connected is it not?

[young stratus]

like this

[lapis shale]

ahaaaaa

that's my problem

[young stratus]

those play slots always need to be connected :)

[lapis shale]

I don't really understand, why is it necessary to connect the white line? what does it do?

[young stratus]

it is like a river

that determines what gets ran in what order

[lapis shale]

I only have experience with nodes in blender and there, you're really only passing data and not when to execute what haha

[young stratus]

you set up the data correctly, but never told unreal to actually run it

[wraith finch]

Hi. maybe a stupid question. (new to unreal)
how do i make a cube fly towards the character while the character is moving using blueprints?
no need for collision or pathfinding.

[young stratus]

yeah, welcome to unreal, this is how you do it here

[lapis shale]

kek

thanks!

[young stratus]

no worries

[young stratus]

if you want a straight line: lerp between the player world location and the cube

[wraith finch]

how do i do that?

[cyan bone]

https://blueprintue.com/blueprint/a89s-d3a/
Sorry this is perhaps confusing. I would ignore the collision mesh generation (its in the construction script). Because its working fine.
And the collision is also working else it wouldnt print. And it would not stop movement of my character when its target character.
It just boggles my mind because its only the stop movement.

[young stratus]

you right click in blueprints and type lerp

[thin panther]

Those white lines are the flow of execution, yiu can see them being highlighted when you look at a bp at runtime

[young stratus]

that expects 2 vectors

in your case the cube his location and the player his location

[wraith finch]

how do i get the player vector?

and do i do it in tick or event begin play?

[young stratus]

get actor location

yeah in tick

cause you want to move the cub every frame

cube*

[wraith finch]

actor location for both player and cube?
then how do i connect the player?

[young stratus]

you mean the different blueprints?

[gentle urchin]

lerrping is best done with static vectors

[wraith finch]

how do i connect the player to get actor location?

[gentle urchin]

alternatively you can do VInterpTo

or VInterpToConstant for linear speed

[young stratus]

Defy, you might want to look into a blueprint tutorial on youtube

[wraith finch]

i did

[orchid grove]

So I deleted a BP asset and replaced it with a new BP asset but I now can't seem to rename my new BP to the name of the old BP. Is there any way to do this?

[young stratus]

I could explain it all but that would take time

[lapis shale]

If i may ask another question, how does "IsWalking" determine if the character is walking? Now, it seems to always be true while my character is standing still.

[wraith finch]

but they r all so complicated when it comes to enemies

[young stratus]

go to programming parlor

i have a bit of time

[steady night]

@lapis shale its the speed that determines it

[lapis shale]

so if the speed is not zero that's walking?

[steady night]

yeah i think so

u can set the "minimum value" somewhere

[drifting peak]

@cyan bone it does seem very strange

because the flow goes through and you tested it

[cyan bone]

Oh i see. Only one collision is working. Its still misterious though.

Only one army collision works. i dont know why

[drifting peak]

@cyan bone can you set the cast to a variable

then drag the get variable, right click and convert to isvalid

drag the cast on the false valid

on true valid you continue all your nodes

[cyan bone]

So thats like while its not true keep checking until its true?

[drifting peak]

yes

i dont have my computer rn

[gentle urchin]

Needs some breaktime

Otherwise infinite loop

[drifting peak]

@cyan bone let me know if this works

idk what else u could do lol

[blissful inlet]

Thanks !

Not sure it's the right channel, tell me if I should delete my message

[cyan bone]

https://streamable.com/yuahql
Didnt work. Its the collision. For some reason it only works on one actor. You see its printing "collision is working". But its printing only once. If both actors are colliding, then it should print twice, right? So only one actor is stoping movement the one that is already stopped, it seems.

[lapis shale]

oh ma gawd i did it

i'm a genius

[steady night]

@lapis shaleNoice

[lapis shale]

my lil kitty is now walking right

[lapis shale]

Weird how in blueprint you have to specify what executes when. Does it matter at all if i for example execute the bottom variable before the top one?

[cyan birch]

How is it weird that you have to actually tell the engine what to do? XD

[lapis shale]

i'm just used to blender

not saying it's a bad thing just surprised me

[cyan birch]

I mean, it would be pretty problematic if the engine just fired off your nodes at random.

Blender's nodes also fire off in a specified order?

[drifting peak]

@cyan bone you only get one print string if it is in one bp

add a rect collision check around the actor

and put it through tick (just for debugging) and it should print multiple times as it overlaps

[flint mulch]

how do I get this vector float, I drag from my box and type float but it doesn't come up, do I have to right click to add it?

when I try

[drifting peak]

right click on the yellow output

then separate

@flint mulch then you get x y z

[flint mulch]

I'm trying to recreate the first image

but whenever I type float it doesn't come up

[drifting peak]

thats vector multiply float

[flint mulch]

yes but for some reason it doesn't show up when I search it

[drifting peak]

you type in vector x float

uncheck context sensitive

on top right

[flint mulch]

ok

[spark steppe]

vector multiply, then rightclick the 2nd input pin and pick convert to float

[drifting peak]

do * instead or x @flint mulch

[flint mulch]

neither of those come up for me lol

[drifting peak]

even if you just click on the graph itself?

[flint mulch]

yes I tried it away from graph too

[spark steppe]

just type *

in the search field

it should show up

or type multiply

they renamed those nodes

and they aren't typebound anymore

[drifting peak]

if it doesnt show up then restart your ue5 lol

[flint mulch]

all I get is multiply by pi

yeah I will

[spark steppe]

restart wont change a thing

[flint mulch]

hm

this isn't the first time something doesnt' show up for me

the description from the one in the image says scales vector by A and B if that's any help

[desert juniper]

UE5 doesn't have that option anymore

Just click that multiply

then right click on the pin, and change it's type

[desert juniper]

yup

just use that one

[flint mulch]

float single or double presicion

[desert juniper]

it's a smart multiply node now. they got rid of all the 'multiply float, multiply vector,...' nodes

[spark steppe]

double

[desert juniper]

and made it a single node with a wildcard

[flint mulch]

I see, thank you guys so much sorry if I was blind I'm still learning this

[spark steppe]

that's why you still better learn on UE4

most tutorials are based on their UI

[flint mulch]

is there a way I can see all of the changes?

because I have done alot of work in UE5 and don't feel like changing over versions anyways

[spark steppe]

guess that would be a long list... and if you already have a lot in UE5 it's most likely better to stay on UE5

as you cant just load your UE5 stuff in UE4

[flint mulch]

it's alright I'll find it online

or just trial and error everytime something is different

[gusty shuttle]

Hey guys, brain farting on collision issue here. Goal is to shoot skel mesh with trace, and trace applies damage to actor bp

[dawn gazelle]

My guess would be that it's failing here. Usually you don't have reference to a specific actor before runtime. If you want to check if the actor being hit is a certain class, a cast of the actor to that class should suffice.

[gusty shuttle]

@dawn gazelle Cool, I'll try casting

[desert juniper]

Another thing to try: skeletal meshes are usually on trace channel Camera by default

big tip. learn to use the debugger.

[desert juniper]

click on the Branch node, and click F9. then play your game and trigger whatever you're trying to do

they game will stop and take you to the node

[gusty shuttle]

Success, seems like the cast worked. I'm doing some testing as is. I've worked with traces fine before, just brain farted haha

[desert juniper]

then you can just hover over all the values, and determine if they are what you think they should be

[gusty shuttle]

@desert juniper I'm familure with debugging my friend, it's been a long day haha

[desert juniper]

sounds like you and I need a fresh cup of coffee 😄

[gusty shuttle]

I usually stop around 3pm, but it's almost 6pm now. I was on a roll and wanted to finish up with the shooting mechanic. I slapped in aim down sights, decals, particle effects, sounds, animations and the last thing I wanted to do was make sure whatever I shot actually got the trace haha

But yes, time for a break until tomorrow, indeed

[desert juniper]

was up till ~130am last night for a similar reason. just wanted to get it done

i know the feel

[dusk cave]

I feel like I did everything

[trim matrix]

Hey guys, do you know how to remove/reset all variables/local variables/reference in a BP?

[dawn gazelle]

Local variables are reset with each execution of a function. Fairly certain for all other variables, you'd have to manually reset them yourself. An alternative would be to spawn a copy of the actor with the existing actor's transform then destroying the old one, thus resetting everything except its transform back to defaults.

[trim matrix]

awesome will do!

[orchid grove]

Is there a way to attach a bone to a scene component or something like that?

For a Skeletal Mesh Component

[valid juniper]

Is there a way to dynamically chose the 1rst map to load instead of using the default one ?

[obtuse herald]

Load an empty map and decide which map to load in the level blueprint or something

[cyan bone]

But thats what the mesh collision is doing. You see the grey thing ? Thats the mesh that i generate in the construction script. I dont know why it is only working in one of the actors when they collide. When they are the same blueprint. It should both trigger overlap event. If one triggers, why doesnt the other trigger. Its so weird.

[dusk cave]

Hey yall. I'm trying to figure out how to have the player pushed smoothly by a platform rather than being teleported when they overlap. This is the only solution I have that gives me something close to what I want. I can't use Add Impulse because the teleporting issue only happens when my player is not moving and I want the smooth pushing disregarding what direction the player is facing.

[flat coral]

Is there a way to trace such that it intersects an object whose collision is OverlapAll? The goal is just to have the hitbox be different than the pawn's collision mesh.

[signal hornet]

I'd imagine just specifying the object under 'actors to ignore' on the linetrace node would do the job

[flat coral]

No the issue is the line trace isn't detecting this object at all, it hits the wall behind

[signal hornet]

Hmmm.. I'm not too sure then. Definitely sounds like an issue with the meshes collision settings though.

Unless there's something on your linetrace sequence that causes it to do that.

[flat coral]

Oh you have to set the Visibility trace to block

[pulsar path]

is there a node that allows me to loop something until a secondary execution pin is triggered?
i just want something to start when the player presses a widget button, and stop when they let go. i could easily do it with a variable (which is what i have atm) but i was wondering if i could do it without a variable

[thin panther]

you could always set a variable for a timer

so on press start looping timer or whatever

on release clear timer

[pulsar path]

[tight schooner]

Set Timer By Event, in other words

It's a node that you can use to loop an event on some interval

[tranquil gorge]

Hello everyone! 🙂 does anyone know if you can set some type of bounds or collision on the camera's FOV so the characters wont be able to move outside of what the camera can see.

[thin panther]

Typically you parent ur camera to ur character so that doesnt happen

[serene bramble]

edit fixed

[tranquil gorge]

hey saw that you left a replay. ty 🙂 my game involves multiplayer and there should be a max distance to where neither of the characters are off screen. like getting to the distance where you are on one side of the screen and the other player is on the max view of the other side where you are both on screen should prevent you both from moving anyfurther with like an invisible wall. thats kind of what i was going for. any tips

[pulsar path]

sry for the delay, the braincells that i have on really overthought how timers worked and it led to me being confused for no reason lmao. its working perfectly now though, thank you
ive also learned something new i could use in the future too, so

[thin panther]

ah multiplayer ain tmy strong suit but i wish you luck

[thin panther]

no problem, i think we all hit that point lol

timers are great

although if you need super quick timers just use a tick instead

[tranquil gorge]

thats ok i appreciate your time 😊 have a good one 🙂

if anyone else might know the solution to my issue its posted a few lines above and id be very greatful

[pulsar path]

if your camera is static, thats easy since you can just make the boundaries as seperate collisions
if its moving, you could make some collissions that are children of the camera and align them to the cameras fov, and just make them as long as you need them to be

second option prob better either way

[serene bramble]

How do I give a umg widget "focus"?
I'm trying to use on key down but the event only works if I hold right click in an element in the widget

[sudden nimbus]

prepare to be annoyed

[serene bramble]

Happy to an accept a "not possible" if needed lol

[sudden nimbus]

oh its possible

[serene bramble]

I just want Esc to set my widget visibility to hidden basically. This is in a main menu context so no players or stuff

[serene bramble]

Guessing it's then hard

[sudden nimbus]

Well first, there's "Is Focusable" but im sure you've found that

[serene bramble]

Yeah, setting that to true basically means if I hold left click/right click anywhere the on key down event fires fine

Or clicking once anyway

[sudden nimbus]

if you tab to it so that it is highlighted, it should receive key events

it sounds like you want Esc to function globally, regardless of whether you are in UI mode or game mode

and for that there is "Game and UI" mode iirc

the way I did it is to have the "menu" key be a game input, and ensure that I'm always in both a game and UI mode

if that works for you, its the easiest

[serene bramble]

I assume you mean Action input? If so then I have one of them

This is in my main menu so I have a level that you first load into that instantly sets the controls to UI only, then opens the main menu widget

So I'm probably guessing I need to change from UI only

[sudden nimbus]

yeah but if its UI only, then the focus heirarchy is in charge

let me do a quick search, there's some good resources for this

[serene bramble]

Alright, happy to change code up a bit if needed

There's no player character or anything in the main menu 'level' so I don't have any real use for input in the normal level space

[sudden nimbus]

ugh i feel like this is because of the unreal wiki shifting

someone somewhere has a flow diagram of how input moves throughout the system and how to hook into it (the right way)

but google has become a potato

The closest you can get is the official docs ("Input Processing Procedure") at https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Input/

So I'm probably guessing I need to change from UI only
If you made the Esc key an action that would fire in game, then yes, making it Game and UI would let you reuse that

thats how I've got it set up, just use it as a toggle. However, this means you need to specially handle the game input itself. For instance, you need to stop taking input from the player character, etc

That part isn't terribly hard though

There's other ways to tie into the keyboard handling independent of focus, but it's more difficult

Also you might find better answers to all of this in #umg 🙂

[serene bramble]

If I change it to game and UI only, then I can suddenly move and look around in the main menu which is weird lol

[sudden nimbus]

yes this is what i meant

However, this means you need to specially handle the game input itself. For instance, you need to stop taking input from the player character, etc

[serene bramble]

Ah. Going to be the noob then and ask what I'd need to do that?

Setting to game and UI does make the Esc work though :)

[balmy apex]

I'm slightly stuck again. I'm trying to get a crouch function into my game and it's not working at all as far as I can tell. Here's what the BP looks like:

[tranquil gorge]

ty for the reply i will try this later 🙂

[elfin wolf]

make sure you click on the character movement component and enable "Can crouch"

[serene bramble]

Hm

Is target being "self" ok?

[sudden nimbus]

in this case its the actor itself disabling its own input

could be from anywhere though

[balmy apex]

I can't seem to find the character movement component?

[serene bramble]

Disable input set up but can still drag around

I don't think there's any actual actor in the world so

[sudden nimbus]

ehhh yeahhhh

[elfin wolf]

it should (when in the blueprint editor) top left, just below your character mesh and collider and stuff

[sudden nimbus]

the default player controller does that--- i was thinking about launching a menu during play

I just want Esc to set my widget visibility to hidden basically. This is in a main menu context so no players or stuff

Oh, this is so that you can control the main menu with keyboard, and have esc go "back" I guess?

[serene bramble]

Pretty much, so you can hit esc to close the settings menu sub menu. Which works fine now

🤔 actually disabling input stops the Esc from working

[balmy apex]

Found it, I was looking in the character itself

[serene bramble]

With disable input off, I can open the menu then either hit Esc to close it or just use my normal close button

Though as in that gif above I can drag/pan around the empty world behind

[balmy apex]

Well, things move when I crouch, but the camera doesn't.

[runic parrot]

Hi everybody! this is driving me crazy.
There's 3 meshes on this image, i want to merge them together into 1 mesh and have the base position centered at 0,0,0.

I just can't do it, it always comes up moved to some place

does anyone know how to fix that?

This is the image of how the new mesh is moved after merging

[gentle urchin]

There's also the listen for input nodes which can consume the input. Altho not sure that works for axis events with pan/tilt. How about just having a pawm without that ability in the first place, for the menu?

[runic parrot]

Just in case anyone has the same problem, just go to modeling tools (install the pluging if you don't have it) and change the pivot of the object, it's literally 2-3 secs.

[serene bramble]

I have no idea how to make that, but sounds like it'd work sure

[runic parrot]

Keep the focus on the UI, Change input mode to UI only and override the ui "OnClick" function and just change it to "handle" so the click doesn't keep going further.

[gentle urchin]

Just a new basic pawn, used strictly in the main menu

[runic parrot]

i think the exact name is not "OnClick" but it should be easy to find.

[balmy apex]

The camera height for crouched vs. not crouched is half, but it just doesn't seem to move anywhere unless i look at the ground. It's weird.

[gentle urchin]

Or no pawn at all , which apparently was an option aswell

[runic parrot]

i think that what you are trying to get is to be able to click the UI, not move it and that the input for your Key, closes the UI. Right? if so, that what i mention should cover it.
Just close the one on focus and override the click function

[serene bramble]

Can't use UI only as then the keybind doesn't go through

Though I'll try the 2nd

[runic parrot]

What is your goal and your problem? so i don't get it wrong, i checked the last posts but can't quite get it

i just solved a 2 hours problem that was 2 secs of work, so i'm quite happy, we can fix that one for you

[serene bramble]

I want keybinds (in this case, Esc) to be handled when UI is open. Setting the input mode to game and UI does that but as a result I can click and drag behind my UI to pan around the empty level. Which I want to stop

[runic parrot]

okey, overriding the click should handle that. keep it at Game and UI and change this

1 sec, let me check on my other project

[serene bramble]

Okay

[runic parrot]

Try with that

what that is going to do is that when you click on the UI, the Engine received that the click has already been handled and won't keep going any further

[gentle urchin]

Is a button a click?

As in, is esc a click?

I always assumed it was mouse only

[runic parrot]

If that doesn't work, you may want to try with going to your controller and disable "Touch events" so you can click, but not drag.

[serene bramble]

I assume this is all to be done in the UI widget?

[gentle urchin]

Yes

[runic parrot]

yap, the big widget that is covering the screen

if the widget does not cover all the screen and it shouldn't. try removing touch from your player controller.

[serene bramble]

Er, I only have UI elements in the widget. Nothing actually covers the full screen

[fresh timber]

hello,

I have a project that I started with the FPS character in it
but I want to use the rolling ball

to do so, I installed UE4, downloaded the template project, updated it, and it works fine in UE5

however, I copied and pasted the ball BP and starting point into my scene, but it doesn't work: it keeps spawning the character
I tried to find some reference that I could replace with the other actor, but can't find anything
is it hard coded in the character code?

how do you change this?

[runic parrot]

The canvas is the UI

Change from design to Blueprint

[serene bramble]

Ah

What do I select to get those details to show?

[serene bramble]

🤔 by the way is that ue5? I'm on ue4 if it matters

I think I'm there though

[calm citrus]

How do I make the line trace always come out of my left side? No matter what direction the player is facing

[runic parrot]

the first cap is on ue4

[serene bramble]

Okay

I'm just not sure where to find that 'touch events' setting

[split ginkgo]

Is there a way I can check if an action mapping is pressed?

[desert juniper]

instead of get forward vector get right vector, and multiply it by a negative distance value to get the left side

[half portal]

Does anyone have a tested tutorial or know how to do double layered healthbar with second bar that lingers behind the one in front

[runic parrot]

The touch one should be on your player Controller under Class Defaults

[serene bramble]

Okay I'll give that a shot

[balmy apex]

Still trying to figure out why my crouch doesn't work but haven't gotten any leads

[balmy apex]

Found a tutorial and this is what I have now, it works

[gentle urchin]

Have you enabled crouch in the cmc ?

oof that cant be a good idea haha

[vocal kestrel]

I've done a decent amount of searching, but i'm coming up blank. I think i just don't know what unreal CALLS these symbols, so i really don't know exactly what i'm looking for.

[obtuse herald]

Win + .

[vocal kestrel]

holy shit wow okay

[desert juniper]

TIL
always used win + ;

didn't know there was a second shortcut

[vocal kestrel]

1. i had no idea that was a hotkey on windows, and 2. okay so it's just that unreal supports emoji text formatting? Does it pull direclty from this default windows list of emojis?

[desert juniper]

it's a universal emoji thing

👿

see, discord converts it

[balmy apex]

That's the first thing I was told to do, yeah

[vocal kestrel]

Ah, i see, Unicode's a big blank space for me, i wasn't aware htat's how it worked but considering broad universal support of emojis that makes total sense.

if i want to add the unicode value in text, do i put like :U+1F601: around it? {U+1F601}? Not sure what the start-stop syntax is here

but i suppose it doesn't mattter if i can pull up a list with a hotkey an djust click

ANyway, much appreciated!

[balmy apex]

Could it have not worked because I'm not using one of the UE5 like starter "games" and I'm instead basically going from nothing?

[gentle urchin]

Perhaps, hard to say. Did you set half height in the settings aswell?

[balmy apex]

It says it's 88

I don't know if it'll help, but this is how I have the character blueprint set up

[desert juniper]

Events don't seem to trigger on dynamically added components.
Is there something else I need to do, to get them to trigger correctly?

[elfin wolf]

shouldnt do once only do something once? but when i hook it up to an event tick it just keeps firing

Oh dw it was in a function and that was causing it

[serene bramble]

Is there an event for a widget's visibility being changed?

[half walrus]

Idk is there? It's a question I have too

[gentle urchin]

Isnt 88 default? Set it to 44

[gentle urchin]

I think theres a delegate for it

OnVisibilityChanged i think

[gentle urchin]

They do on mine, no magic added

[serene bramble]

Yeah I worked it out, ty though

Is there a way to save custom settings to Game User Settings?

is there actually a good math lib for bp with smoothstep, slerp, lerp and whatever?

[gentle urchin]

To text handles the display precision^^

[leaden dock]

aaah

nice

thx 🙂

[sleek dust]

what i need to put on 'object'? i have a pawn and i want to posses it from other blueprint

[gentle urchin]

A reference to it

Cast is a typecheck, it needs something to check the type of

[leaden dock]

yeah without the object reference you are casting a nullptr to spaceship

do you want to spawn a new object/actor/pawn? or what are you doing there?

[gentle urchin]

Its probably easier handling this in the spaceship

[sleek dust]

so, i have a first person player who you control when starting and i want to change the player to spawn a space ship then you can fly it

[gentle urchin]

Since theres a global get'er for player char/pawn

[leaden dock]

then you need to spawn the actor

and then posses it

[gentle urchin]

^

[leaden dock]

casting is just a type conversion

it doesnt spawn stuff

[gentle urchin]

The returnvalue of spawn is a reference

[leaden dock]

like casting from int to float

[desert juniper]

didn't work when I tried it.
It's being added at runtime, so the component is stored as a variable
when I tried implementing the event, it wouldn't fire

but adding the component as normal to the actor did cause it to fire correctly

[lime cairn]

Basic question, if you have an actor in an array, and you destroy the actor, will it be removed from the array as well or should I take care to do that before destroying it?

[tight schooner]

It resizes the array I think, which can have weird effects if you're looping through an array and destroying the things in it. There's another macro called ReverseForEachLoop for destruction purposes

[gentle urchin]

Sure the settings were equal? What component was it

[lime cairn]

Thanks!

The fact that the positions of ArrayIndex and ArrayElement are switched is annoying me

[dapper bramble]

Does someone have an idea why this variable might be null when accessed, despite it successfully adding to viewport?

[shrewd temple]

Hey, guys. I have two blueprints (BP_A, BP_B), can I force them running in fixed sequence?

[balmy apex]

That seems to just make the capsule shorter

[gentle urchin]

Which is what crouching is

Then thenisCrouching should be true

Which gives you a transition

In your animBP

[balmy apex]

No, I mean before pressing crouch. It just makes it shorter by default

[gentle urchin]

Oh

[mellow folio]

post more pics of the code before that, and of the error

[dapper bramble]

There is nothing. Just begin play and create widget node

[gentle urchin]

Also no need to check if the return is validn

It will be when executed

[mellow folio]

then show when it is accessed

[balmy apex]

This is correct, right?

[mellow folio]

there is no typical reason for something like that to happen, and the code you posted is fine, so you must have done something wrong somewhere else

so you need to post pics or describe why you think this is failing

[dapper bramble]

I think I found it @mellow folio . I was trying to access it from the server (whereas it only exists on the client)

[balmy apex]

This works, but "Crouch" and "Un Crouch" do not

I would prefer for crouch to work so I can make it that players don't walk off ledges when crouched

[tight schooner]

Which part of it? For BeginPlay idk. For Tick, you can actually set the actor's "tick group" which affects when tick is run e.g. pre-physics, post-physics etc

[shrewd temple]

For BeginPlay, what is idk?

[balmy apex]

This is the tutorial I used for crouching: https://www.youtube.com/watch?v=KI-zsgcrJ80

[mild jackal]

Hey I'm really, really new to Unreal Engine and I was trying to have a system similar to the game SuperHot where time slows when you don't move. I was wondering how I can change the default time dialation or a way to run a blueprint when the game starts to change the time dialation to 0.05.

[tight schooner]

idk = I don't know

[tight schooner]

Idk if there's a default parameter offhand, but whatever BP you're using to manage the amount of dilation can set it on Event BeginPlay as a quick fix.

[mild jackal]

Alright thanks!

[brazen pike]

Yeah off beginplay 'set global time dilation'

[shrewd temple]

Thank you. I think the only way is using a dispatch event.

[brazen pike]

Surely the difficult part would be having it change when moving? But yeah set it to 0.05 on beginplay

[mild jackal]

Yea, I just didn't know about the BeginPlay event due to how new I am with blueprints

[mild jackal]

One more question. What blueprint class should I place this in or does it not matter?

[finite island]

anyone knows about this?

cant find the node, unless i have to set it up myself

[amber hill]

I have a actor_pb that isnt selected in the gamemode that should move a object. Is there anyway I can use this without setting the BP in the gamemode?

The movement definately works if I have the Default Pawn Class set as the BP in the gamemode.

[jagged stone]

Do you mean you want to be able to move the object without having a controller possessing it?

[tight schooner]

It's an architectural question and people will have different opinions on it. So IMHO, because your game revolves around it and potentially many actors could affect time dilation, you should make a wholly new actor class (or subsystem if you're a fancy pants) that only manages the time dilation. Drop one of them into every game level (or make the Game Mode BP or w/e spawn it on BeginPlay). Then other actors find it and talk to it, telling it how to change dilation. Then your Time Dilation Manager actor does all the smooth, Superhot-style ramping of dilation values.

Another option is to put all that functionality into your custom Game Mode class itself rather than making a separate manager class that you need to place/spawn into the level.

[gentle urchin]

This is what a hard reference looks like in the level blueprint

[finite island]

what does that means?

[amber hill]

I think so, I have a another BP which does all my camera stuff.

With this BP I just wanna be able to select something then right click to move it.

[finite island]

how can i obtain it

[jagged stone]

So you need to use AI Controller instead of player controller; in the "Simple Move to Location" use "Get AI Controller" as the Controller input (instead of get player controller)

[gentle urchin]

Select the item in the world,

Open the level bp

Right click

Get reference from 'selected object'

@finite island

[finite island]

hold on

[jagged stone]

Does anyone know of a Blueprint node that can extract the Animation Sequence from an Animation Montage (so given a Montage i want to know which Sequence is in the Default Slot)

[amber hill]

Thank you, Get AIController return value wont connect to Get Hit Res though.

[gentle urchin]

May i ask why you need this?:p

[jagged stone]

@amber hill You still use the player controller from the result under hit

But just use the AI controller for the move controller (so get location from player controller, so move controller as AI controller)

[amber hill]

Ah so like this?

[jagged stone]

Yeah i think so

[amber hill]

Thank you I will try that

Nope didnt work

[finite island]

wait, what do you mean "level bp"?

[jagged stone]

@amber hill also put a reference to the object into the "Controlled Actor" input ont he AI controller

"self" if this in within the moving object's Blueprint

[amber hill]

Like that?

[gentle urchin]

The blueprint for the level..

[jagged stone]

No, the object that you want to move, (so what are you trying to actually have a move? like a box or something?)

[amber hill]

Skel Mesh

[finite island]

i am there but cant find what you talk about

[finite island]

@gentle urchin wait, found it, now what?

[brazen pike]

You can't make that a pawn?

[amber hill]

I have it as a character class

Should it be a pawn?

[jagged stone]

@amber hill put a "self" reference as in the "Controller Actor" on the AI controller

[amber hill]

How do I do that

[jagged stone]

right click and add node of "self reference"

Then connect that to the AI controller input

[amber hill]

Yeah I dont have that option

Nvm I think I figured it out, Like that?

[jagged stone]

Yes

[amber hill]

I was right clicking the box haha

Sorry

Still hasnt moved it though

[hot lotus]

Hi everyone, is it possible to set variables in a AnimNotifyState Begin function to use it in the tick? The variables I create are readonly.

[jagged stone]

Also i think to make this work you will need to add a "NavMeshBoundsVolume" to your scene

[mild jackal]

Is this all that's neccessary? Because it's still not working but It may be something else that's wrong

[amber hill]

Done that

[jagged stone]

And everything inside the scene is into the NavMesh right?

[amber hill]

Ive not coated the entire scene?

Should I?

[jagged stone]

Just scale the navmesh way bigger so that your whole scene is contained in it

The Ai controller won't be able to move the actor if it can't find a clean path (paths are generated by the Navmesh), or if the end result will be a collision etc...

[amber hill]

Done

Tbh the debug isnt even showing Ive clicked the mouse

[jagged stone]

If i can't get to the desired point it just does nothing....you might want to debug by just trying to move your actor over like 100 on the x or something (because your click point might be bad)

[amber hill]

Also its still building navigation

[cyan bone]

Im having this issue since yesterday.
This function generates a procedural mesh that is a cube around my character.
Call it on construction script.

https://blueprintue.com/blueprint/l1gelwsb/

I then create a overlap event for this cube procedural mesh in the event graph.
I copy the character in Level map. To have 2 characters to test.
And only 1 of the characters triggers the overlap event.
The other does not, i dont know why.

Is it possible that procedural meshes can bug somehow and not detect overlap with other procedural meshes?

Here is the video, of the problem, pls help me:

https://streamable.com/d68gl1

[fiery knoll]

Where does your proc mesh sit in your hierarchy?

[cyan bone]

There.

@fiery knoll

[atomic thorn]

How can I see in BP simulation where its at ?

[fiery knoll]

When actor A starts overlapping B, only events on the root collider of B will be triggered. Make your Proc Mesh your root OR implement the overlap event on the capsule.

[finite island]

anyone knows what's up here? i have a mesh that is supposed to move back and forth forever, but it is only doing it once

[fiery knoll]

You can put breakpoints or select a debug object in the toolbar

[fiery knoll]

Your timeline only plays once probably. You can reverse play it when it's finished playing and restart it when it's back at zero.

[finite island]

how do i reverse it?

like what should i connect it to

[fiery knoll]

If you look at your timeline node there is an exec input to reverse it (from the current position) or reverse it from the end.

[stuck plaza]

Is there any epic approved convention when naming data only blueprints?

[finite island]

reverse it from end?

[fiery knoll]

It's the opposite of 'Play from start' (and thus means: Play from the end back to start)

So that means the procedural mesh collision behaves differently than a box collision?
I tried making the procedural mesh collision the root and it doesnt let me either. It doesnt let me move the procedural mesh component to become the root in the hierarchy
If both have a box collision it works perfectly. I dont understand why with a procedural mesh collision it ignores 1 of them.
The other alternative making the overlap event on the capsule does exactly the same thing, it only detects 1 of them.
This the topdown template, with only just a procedural mesh. Pls help me.

[stray kayak]

I believe it would still just be BP_{AssetName}. There's nothing specifically for data only ones

[atomic thorn]

Does delay stop loop exec for the delay time ?

[unique wasp]

In a material function blueprint, how can I see the type of a pin/connection?

(I get an error that I'm mixing float3 and float, but they should both be float. So I'm trying to follow the path and see where it accidentally turns into float, but I can't see the types of the connections.)

[fiery knoll]

I assumed you were moving the actors by setting their location and sweeping. Hence my suggestion. (see the tooltip for that node)

[gentle urchin]

Just mask it or append to the other :p

[unique wasp]

The Mask and Append nodes seem to be the same regardless of whether a float or float3 goes in, how can I see type based on that?

[gentle urchin]

Mask can make a float 3 into a regular floatz or float2,

[unique wasp]

(Note that I did just find a solution: make a ConstVector2, put it in multiply, put the other thing in the multiply too and check the error to see the type of the other thing)

[gentle urchin]

Append can do the reverse of that

Not sure how to check the pins specifically really

[cyan bone]

So does this apply to my situation? Im not sweeping, it is a plain topdowncharacter with the native movement, with just a procedural mesh. It is detecting overlap only in one, and both are the same. Can i upload the project via wetransfer? Pls help me.

[unique wasp]

I know what mask and append do. My problem was: it shouldn't be a float in the first place, so I was looking where I went wrong and couldn't find info.

[tight schooner]

No, loop bodies execute all in the same frame, so it'll choose next case then call the delay node however many times in 1 frame, and then the delay output will execute sometime later. If you want a recurring event, look into the node, Set Timer By Event

AFAIK @unique wasp in the material graph, data is untyped (I think that's the right term...) so you don't really know what it is until it throws an error. Also material graph questions are better asked in #graphics cuz it ain't BP

For material custom functions, if it doesn't say what the type is on the pin, you can examine the function itself

[cyan bone]

@seanny could you give me your hint on this issue? it is giving me so much pain 😦

[icy dragon]

Not if it's outside the macro

[tight schooner]

@cyan bone sorry dunno about procedural meshes

[icy dragon]

The loop happens inside that macro, to add delay, you're pretty much have to recreate the for loop macro but with delay in between, or use timers iterating through the integer and invalidate once the last index reached (essentially pseudo for loop)

[atomic thorn]

K I'll make my own loop ty

[cyan bone]

@icy dragon Could you help me on this issue please? Should i upload the project too?

[gentle urchin]

Try it on beginplay instead of construction script

[icy dragon]

No

[cyan bone]

Same issue. It only detects one of the characters.

[visual lake]

I'm fairly new to Unreal, and trying to set up a spline mesh blueprint while I blockout an environment I'm working on, but this BP I found online doesn't quite fully work.
Whenever I add more than one spline point the mesh disappears.

I think I get the gist of how this works overall but I'm lost when it comes to finding a solution for this issue

[visual lake]

Okay think I got it actually

[jagged stone]

With Events & Timelines; if i run the event multiple times will each time interupt the previous timeline operation? For example I run the event 10 times in a row, will i end up with the timeline running 10 times concurrently, or it will cancel the previous timeline and start again?

[pearl tangle]

In Multiplayer, what's a good way to update Player State from Game State (I'm getting Player State Array, looping it, and calling an event inside Player State to update the value), but then when I'm calling another event in Game State the value wasn't updated... (UE5)

[fiery knoll]

AFAIK it will restart the single instance. Try it out to be sure.

[tame pecan]

Updated for who?

Are you calling it on the client?

[summer jetty]

Is there a way to get a widget to close/remove from parent when the player clicks anywhere outside of it? I know you can do it the other way around, but I can't find any method or doing the opposite (or I could be googling the wrong term).

[pearl tangle]

@tame pecan I'm trying to get the updated value on the Server in Game State, by getting the Player State Array again, looping it, and finding the value (using it for a branch)

[silk cosmos]

Not by default. You'll have to check the focus of the user and when it changes

[pearl tangle]

@tame pecan Here is the flow: The First event is being called from Player Controller with Authority -> Server Event -> Loop -> Call client event in Player State to Set value -> Player controller fires another event with Authority -> Loop and get player state value -> Value not updated

[summer jetty]

oh ok, cheers 👍

[harsh coral]

hey there....
Could anybody help a complete blueprint beginner out?
I need to animate some blueprint parameters (booleans that are switching out dynamic materials inside the BP) in sequencer and then render it out using Movie render queue.
It works fine when scrubbing the timeline and also when using PIE, but NOT during rendering via Movie render queue.
I´ve been playing around with copying stuff from the construction script to the event graph and wiring an event tick into everything, but nothing worked so far.
Maybe there is a simpler solution I ´m missing, like creating a specific game mode that simulates what happens when I hit "simulate" to Play in editor and use that as a game mode override in Movie render queue...
The blueprint creator wasn´t able to help me so far.

[half portal]

Yoyoy guys, Im havingt trouble spawning emitters at location, any helpers

[vernal lotus]

what specifically?

does it spawn in a weird place?

doesn't spawn at all?

[real garnet]

Structure data is deleted when closing the project

[tame pecan]

Have you changed the struct?

[real garnet]

I just changed the values ​​in it

it happened yesterday after crash

[tame pecan]

You need to resave all blueprints that reference this struct, they usually pop up in the output log

compile and resave

then restart editor

BP structs are extremely weird. Once you have referenced them somewhere and start changing in the struct, bad stuff gonna happen

but usually gets solved by compile/save all bps referencing that struct

[real garnet]

thank you so much i'm trying now

[half portal]

Doesnt spawn at all as far as Im aware

[tight schooner]

You didn't specify a location in your screenshot lol. Location is worldspace, so usually you get an actor or component and Get World Location, and plug that into the Spawn Emitter node.

otherwise it'll spawn it at the world origin (0,0,0)

[vernal lotus]

what seanny said

you can leave the rotation and scale as they are as far as I know

[tight schooner]

yeah, unless your niagara system uses rot/scale for something

[zealous cedar]

Hey all - I set up a Blueprint Construction Script that changes a Light Function parameter to vary the flickering of each light in my scene. The parameter changes the UV offset on a texture that feeds into the LF emissive. The lights in my scene also have a standard material applied to a “bulb”, also with an emissive output. When using the same technique to offset the UVs for this bulb material, the flickering doesn’t match up. How can I solve this? Should I not be using a texture, or can I match the Point Light texture space to the “bulb”? (Obviously LFs can’t use World Position so I’m a bit stumped)

[desert juniper]

it's a custom c++ coponent. just tried it with a simple box collision, and it doesn't work either

[ancient stag]

You can use Unreal's standard "Add Box Collision" node to add a component and then bind a custom event On Begin Overlap.

[desert juniper]

yeah, that was the intermediate workaround, but trying to find a way around that if I can.

[remote meteor]

the binding of blueprint variable events is done on the object construction

if you alter the variable afterthat

it wont fire

so you have to bind it yourself if you add things on runtime

or if you need a simplier overlap

you can use ActorBeginOverlap

[desert juniper]

ah, so doesn't look like it's going to work

yeah this overlap was just a test to see if a default component would work. the cpp component is a bit more complex

Thanks for the help everyone!

[gentle urchin]

If it has the events avaliablez they should already be bindable if im not mistaken

Not sure why you think that wouldnt work for you

[desert juniper]

yeah I can manually bind, but was looking for a way where I didn't have to do so.
it's not a big deal though. I'll just make custom events and manually bind to them after creation

[gentle urchin]

But why?

Why dont bind ?

[real garnet]

not resolved :/

[gentle urchin]

Like what would the benefit be for you :o

[real garnet]

I'm going to delete the structure and create it again.

[gentle urchin]

If you add helper functions for it in a library you can get away with fixing it in only one place atleast

And/or make the struct in cpp

Relatively simple even without cpp knowledge

[real garnet]

Thanks for your advice, I'll fix this and be more careful.

[desert juniper]

Because some component have tons of events that I'd rather not have to manually bind to if I don't need to

Same reason we use a game engine rather than making our own. convenience 😄

[gentle urchin]

I feel dumb asking how its different from adding the event

Like

Its 2 clicks instead of 1, is that all?

[faint pasture]

This. Making a couple data types in C++ is a good way to get your feet wet

[vernal lotus]

I wanna make a terraria style world in 3D

meaning:

• it's not generated at runtime
• Wolrd file is created initially and saved to disk before gameplay takes place
• the world is made of blocks

[mental trellis]

So non-random minecraft.

[vernal lotus]

I'm kinda clueless how to approach this

yea

[mental trellis]

First, you probably don't want to use blueprints.

[vernal lotus]

alright

I can avoid using them for world gen

but for tiles and other game logic it should be blueprints

so idea I had

is to have an array of integers

ints would be block id

so that when it loads it uses the id as reference for what type of block should be in a given slot

is this any good?

[mental trellis]

Probably?

[vernal lotus]

huh

ok

so now what about chunks?

should I group like

1000x1000x1000 tiles into a 3d array

and then embed those arrays in another array?

or is this a bad idea?

or should I avoid chunks altogether

[mental trellis]

Good question.

But I don't see why you just don't use levels instead of chunks.

Basically the same thing, except unreal.

[vernal lotus]

ooo

ok

it would load these at runtime, open world style yeah?

I'm not exactly sure how level streaming works lol

[mental trellis]

Figure this shit out before you design your system.

[vernal lotus]

how exactly levels work you mean?

[mental trellis]

Yes

You should understand what's already there before designing what isn't.

[vernal lotus]

ok

I'll go do that then

huge thanks

[wraith finch]

quick question. when i create a variable in 1 blueprint and wanna use it in another , how do i do that?

[flat coral]

Make it public, get an instance of that object, cast it to the correct class, get <variablename> node

[wraith finch]

object being the blueprint of variable?

[gentle urchin]

Blueprint

[flat coral]

The blueprint is a class (really, Blueprints is a coding language but the terms are used interchangably) You need an instance of that blueprint

[gentle urchin]

Instanced one, in the world

[wraith finch]

..how do i make an instance?

[flat coral]

Either place it in level or spawn it in the world via a BP

[wraith finch]

yes. but. in the blueprint

[mental trellis]

You do it by following some tutorials? 😦

[wraith finch]

:(

[flat coral]

Structural question from me: I've got a lot of pawns that can take damage and die if that's more than some maximum health they define. Because I keep doing this over and over, it would be kinda neat to abstract this functionality into an actor component or something, so I can just add this component to an actor and just like that it can get hurt and die.
The problem is, right now I'm doing this by overriding "ReceiveAnyDamage" on the actor, and I don't think there's any way to access that on a component?

I feel like this is probably a problem others have come across, how to abstract health, damage, and death

[gentle urchin]

Cant you bind to owners (actor) anyDamage event ?

And thus achieve the abstraction ?

Damage is implemented on actor level, and components are bound to be on actors so..

[flat coral]

oh fuck yeah, that's a little messy but it'll definitely work. Thanks!

[paper galleon]

Eh... This is a little bit weird.

The target and the event are mismatched

Will this work?

[gentle urchin]

Id make it a function but thats me 😄

Or atleast use 'create event' node 😂

[paper galleon]

The actor is not the owner of that event

[gentle urchin]

Cleanliness

[flat coral]

I'd prefer it to be a function but how do I bind that to the owner like this?

[gentle urchin]

Create event :)

[flat coral]

I mean that was going to be my next step but the function thing sounded cooler 😛

[gentle urchin]

Event can be a function

Or an event^^

[gentle urchin]

Not sure what you mean by this

The damaged actor from the event ? Or something else

[flat coral]

Happy? 😄

Also yeah the actor is absolutely the owner of the function to bind to its event

[gentle urchin]

Love it !

Next up

Create some dispathers

For the actor to sign up to

[flat coral]

One more question, if I want the owner actor to supply a sorta "on death" function that handles things like ragdolling the right parts and fire and stuff how do to that

oh you probably just answere dthat

[gentle urchin]

^^ dispatchers

Yepp

When selecting the component , the dispatchers show up as the events in the details panel aswell

[paper galleon]

When you bind an event, the event must be a member of the target. But from the original picture. The target was the component owner. And the event was a member of the component not the owner.

Unless I'm wrong. That wouldn't have worked

[flat coral]

ReceiveAnyDamage is an event of an actor, which is the owner of the ActorComponent

In fact that's exactly the problem I came here to solve in the first place, how to access the ReceiveAnyDamage event because it ISNT an event of the component

[paper galleon]

@gentle urchin. This method

[paper galleon]

Nah, you're fine with this.

[obtuse herald]

OnTakeAnyDamage is an event inside actors. GetOwner gets the owner of the component aka the actor its in.

[paper galleon]

That event was custom in the actor component.

The one in the first picture

[wraith finch]

any idea what i could be doing wrong?

[obtuse herald]

Yeah, but where is the problem? The signature of the delegate is the same

[paper galleon]

I was just clarifying something I think he's fixed it.

[flat coral]

To be clear, both versions of the graph I posted are functionally identical

They're organized different but they act the same

[paper galleon]

The delegate system takes a function pointer. And an object reference. If the function does not exist in the object, the delegate will fail.

[flat coral]

Whether I bind a custom event, or link it to a CreateEvent node that references a function, it's the same thing

[obtuse herald]

exactly

[paper galleon]

Just to clear something for me.
The first event you sent was in the actor component?

[flat coral]

Yeah they both are

[paper galleon]

We're misunderstanding each other. I think you're talking about something a bit different

The event here is part of the actor component but the delegate target was the actor. This should fail.
I was asking for confirmation if it will.
The target should own the event passed into the bind event. That is not the case here

[flat coral]

No, the target has to own the FUNCTION

which is the bind function

[paper galleon]

Hover over the yellow highlight and tell us what the error is

[paper galleon]

Nope the event

[wraith finch]

'BP Interface Game' does not inherit from 'Actor' ( Cast To BP_interface_game would always fail).

[paper galleon]

The bind function is just a regular function.

[flat coral]

It's a regular function ON Actor, not on ActorComponent

[paper galleon]

Yep. You can't cast that way.

[wraith finch]

i figured

[paper galleon]

You can pass a message if the actor implements the interface it'll succeed. If not nothing will happen

[paper galleon]

Never mind. I'm clear now

[gentle urchin]

So all good, yes? 👌

Did you try it with the dispatchers aswell?

I never knew thats how they made the external events lol, but it all makes sense really

[flat coral]

I'm workin on it!

The damage logic I'm moving to this is actually more complicated than I let on lol. I've got protections for current health not going out of range, resistances, separate concepts of "damage" and "healing" which can both occur via this channel, etc 😛

[gentle urchin]

What is healing beyond negative damage

[flat coral]

Well exactly, but it needs to know that's happening so it can play cool VFX for it

[gentle urchin]

Fair^^

[flat coral]

Damage is RED healing is GREEN that's the way it has to be!

Colorblind people can look at the health bar and just figure it out

[gentle urchin]

I think you can add and bind to new components within the component aswell (for the range stuff)

If a collision volume would make sense f.ex

[naive stag]

How do I send a custom event to a specific blueprint? Every time I try to give a reference to the object I need the event to be sent to, it gives me an errror

[paper galleon]

What error?

[paper galleon]

And you don't really send to blueprints. You send to an object

[naive stag]

Something along the lines of “Incorrect Reference”

[paper galleon]

Probably what you're sending to and what you're referencing are not the same.

[naive stag]

It is the same

[paper galleon]

Send code?

[naive stag]

Hold on let me take pics

here

[paper gate]

Its rumtime error

[naive stag]

meaning?

[paper gate]

Come vc

[paper galleon]

That is not incorrect reference.
It means that what you're referencing doesn't exist.
Probably wasn't created

[naive stag]

alr hold on

[naive stag]

what, hows that possible

[paper gate]

@naive stag come vc i tell you what its

[paper galleon]

Yeah. Go vc

[naive stag]

i cant speak through my laptop but i can screenshare if needed

im here btw

[paper gate]

Are u listening me ?

[naive stag]

wait

is there any vc

that allows streaming?

so that u can help me fix the issue right away

[paper gate]

You can dm me

[naive stag]

oh lol

true

[zealous cedar]

Sorry to ask again, but can anyone offer any guidance on this?

[gentle urchin]

#graphics is better for this i believe ?

[thin panther]

You are never setting spawner ref

[zealous cedar]

It's kinda half and half so wasn't sure! I'll ask there also

[thin panther]

You have vreated the right type of variable, but it has nothing in it

[flat coral]

Why does Convert Event To Function just do nothing, for an event defined in a component?

[gentle urchin]

Bind dynamically

instead

🙂

with the known Create Event node

[thin panther]

That error always means you are trying to use an empty reference

[finite venture]

hello. i have a problem with making movement

do anybody know what is wrong?

[faint pasture]

Yes, you haven't said what the problem is.

[finite venture]

i cant look up or down

[paper galleon]

Is your camera using pawn control rotation

Or spring arm if you have one

[faint pasture]

Is that input event even firing? Have you tried print the axis value to make sure it's working?

[paper galleon]

True...
