[opal arrow]

How do i make custom gravitation and atmosphere, so when i go close to specified object it starts to pull me like a planet?

[zealous moth]

@errant cliff wut?? Your skeletal mesh has its own skeleton. What you need to do is get the third person anim BP and retarget it to your new skelwton

[elfin wolf]

theres like a million youtube tutorials for that

[light osprey]

Can someone tell me how i can make a dash for top down character template?

[opal arrow]

I couldnt find any

[light osprey]

I know about launch node but it makes the character jump

[errant cliff]

retarget as of define skeleton on bp?

[light osprey]

So is there any way to make a dash for top down template character?

[zealous moth]

No actual retarget. Look up ue4 and retargetting. In ue5 the setup is also different and you need to follow the steps

[errant cliff]

ok ill check thanks

but if I get the error

failed to merge bones

[elfin wolf]

https://www.youtube.com/watch?v=bcTqFA23P9Y

[errant cliff]

it wont work, right?

[errant cliff]

when i tried to assign skeleton to my bp

[opal arrow]

That is for ue4, will it work?

[elfin wolf]

yes

[elfin wolf]

https://www.unrealengine.com/marketplace/en-US/product/control-rig-mannequin download this and add it to your project, then try follow that assetville tutorial again

[errant cliff]

ok thanks will do that now

[elfin wolf]

https://www.youtube.com/watch?v=XjKKUV8SwP8 this will work

[errant cliff]

actually I cant as I only have UE 5.0.. should I also install 4.26?

I guess maybe working on 5.0 is a mistake, more stuff will be compliant on 4.26?

[elfin wolf]

nah, in that case try adding this to your project and using these https://www.unrealengine.com/marketplace/en-US/product/c456f4551dc9416cb9370707450f980e/

[errant cliff]

Ok trying now thanks

ok done

I did the tutorial

loading

I can possess the thirdperson character but cant move it with keys @elfin wolf do you know why?

[elfin wolf]

what does the character bp look like

[errant cliff]

let me check

here @elfin wolf

[elfin wolf]

what are the warnings?

[errant cliff]

hmmmm

😬

[mental trellis]

Are those axes set up in your inputs?

In project settings

[errant cliff]

should be here no?

[errant cliff]

check screenshot i think it is

[mental trellis]

I imagine the axis names have to match.

They do not.

[errant cliff]

also the model look hilarious; lady missing a neck

[mental trellis]

"MoveForward" not "Move Forward / Backward"

[errant cliff]

and no knees looooooool

oh

[subtle nova]

Hopefully quick question. I know how to use "Is Gamepad Key" to detect if the player is using a controller or a gamepad, but is there a way to tell what sort of gamepad it is? Trying to figure out how to display the proper button on-screen if it's a PS4 controller or an XBox controller

[errant cliff]

ok got it thanks @mental trellis i fixed it and now my model looks like its working

[mental trellis]

Awesome!

[errant cliff]

however the lady has no neck and no knees, but i guess the rigged body i imported is not adapted to it.. i can figure it out maybe

thanks @elfin wolf

[elfin wolf]

no problem

[errant cliff]

im 2 days in only, do u guys recommend any material about character and controllers so i can understand exactly what is needed?

also looking for blueprints AI course if anything around

Ok figured it out!!!!!

i got it almost working perfectly

now to the AI part

[proper tendon]

Hey anyone know how to access a variable inside the level blue print?

[mental trellis]

I'm not entirely sure that's even possible.

[proper tendon]

That's what I figured

[mental trellis]

I may be wrong. I frequently am when it comes to BP stuff.

[proper tendon]

well there's a work around I can just set the variable inside another actor and set it from the level

[mental trellis]

You could use a custom world settings class and add it there.

That's where I'd put world-specific settings like that.

[proper tendon]

ah okay I'll try that thanks

[mental trellis]

It's kinda in the name 😂

Good luck!

[errant cliff]

I think I did this wait

you can reference it from the instantiated level

so you still need to deploy it

[proper tendon]

I don't work with Unreal it's only for a uni class so I got no clue what all that means xD

[errant cliff]

LOL

what is your use case

what are you exactly trying to do

[proper tendon]

well I got a specific number of wires that the player needs to connect and I just want to update the UI to say how many there are left

[desert juniper]

Game State is probably where you want to store information like amount of wires hooked up

[mental trellis]

Yeah.

[proper tendon]

andd where is that?

[mental trellis]

You'd create a custom game state class

[proper tendon]

oh I have one already

okay

[mental trellis]

It's a setting in your game mode, I think.

[proper tendon]

Yeah I was just trying to do that

right thanks!

[desert juniper]

Your Widget Blueprint can simple GetGameState and cast it to your custom game state
Then on tick, you can update the number of connected wires text in the UI to be whatever the variable from GameState is

(that's the easy way, but not the right way), though i'd go with this since you're new

[errant cliff]

this is the mustache of a winner

Any recommendation for AI blueprints tutorials?

[jaunty summit]

And you can check pinned messages in #gameplay-ai

[errant cliff]

Thank you and thanks @jaunty summit !

im following https://dev.epicgames.com/community/learning/courses/67R/introduction-to-ai-with-blueprints/jEe/creating-the-project-and-environment first then will check the video and other resources

[snow halo]

Anyone have a quick tip? I wanna set a variable, an enum, and have it call a function or an event. Just like repnotify does except there is no network/multiplayer here. Just curious if I'm missing somethin stupid : )

[fiery glen]

May as well hide the value behind a setter function

And a getter of course

[snow halo]

fair fair. Reason I'm asking is because in this case I'm using sequencer and would love to be able to set an enum in it and have it call a function. I can do this by binding an event that passes in the enum but trying to avoid binding to events in sequencer

[trim matrix]

Why does it not allow me to save my BP?

[trim matrix]

Hi everyone! does anyone know how to delete geometries that intersect a specific geometry (not Bounding box, but geo only)

[rugged wigeon]

@trim matrix you may have two instances of the ue editor open with the same project

[trim matrix]

and if yes, does the geometry to delete has to be spawned? or can it delete manual created actor?

[trim matrix]

It was a bug, I fixed it via Tools -> Validate

[flat coral]

Static mesh component isn't a mesh component? Am I doing this comparison wrong?

[proud sierra]

Hi, I am trying to update Procedural Mesh Component in runtime (on tick) but nothing happens. I use Update mesh section with new data, but still see the same thing that I applied in construct script. Maybe someone of you had the same issue?

[flat coral]

(For future reference, the way that works is to attempt a cast and use the results to determine if it subclasses what you're looking for)

[earnest tangle]

StaticMeshComponent inherits from MeshComponent

However your screenshot is comparing the class to another class

although static mesh inherits from mesh, it's not the same as mesh

But yeah, casting is the way to go

[drowsy radish]

Anyone know the best way to pick up and move an actor on screen using touch input on mobile?

[vapid comet]

is there some way i can get half of the capsule's height and save it as a variable?

[teal venture]

Hey, guys! I was wondering if anyone here could give me some advice on some good UI blueprint tutorials? I'm starting work on a game that'll have a sort of glossary with information the player can click through and read, but I'm honestly a little lost on there to even start building this, since I'm fairly new to the engine (but very eager to quickly jump into it 😆). Any and all thoughts are super welcome!

[tranquil field]

i need someones help, i spent about 12 hours making this simple game (that i can not stand to fully remake) so i saved it onto onedrive, downloaded it on my home pc from onedrive then when i open it all i see is this, no anywhere near the game i made. help please!

[thin panther]

thats an untitled level, are you sure you saved the level before uploading it

[astral epoch]

I don't think this really fits into #gameplay-ai since its not behaviour trees, is there any way to check if a Ai MoveTo node has hit a path point but not necessarily the end?

Say an event call or something?

[tranquil field]

yup. uploaded it a few days ago, literally opened it on a diff computer -today- and it opened correctly, then i open it on my home pc and it f's it up.

[thin panther]

it seems some acotrs arent loaded

try and find what isnt loaded

[astral epoch]

I wouldn't recommend trying to transfer individual files like you're doing, nor using general-purpose cloud storage. You can lose data that way very easily, or run into issues like here where certain dependencies (in this case actors in the level) aren't present.

[thin panther]

i iamgine they uploaded the entire project as a zip

which is alright but source control is still better i admit

[astral epoch]

I should hope so, just the way I read it seemed like it was a single file.

That's what I was going to suggest. Source Control if you plan on transferring the project around... not to mention it serves as a good backup.

And seeing "last updated 2 weeks ago" is good motivation for me to actually start working on projects again

[tranquil field]

thing is i literally did the exact same thing i did just now, 2 hours ago and it worked perfectly. no problems.

[thin panther]

did you upload the project or just a few files

please tell me you didnt do the latter

[tranquil field]

i did ctrl s on every new thing i did, then let it autosave into onedrive a few times.

thats how i do it every time, and it works every time, except for this 1 time.

and btw with the autosave, i let it autosave the entire project.

[thin panther]

first of all dont do that again

second of all do what i suggested

try to find the unloaded actors in you heirarchy

[astral epoch]

Okay not a direct solution to your problem but you want me to find a tutorial on Source Control?
I know a lot of folk at my University who absolutely refused to use it because they couldn't understand how it worked and it lead to a lot of broken projects or people using outdated versions.

[tawdry surge]

Source control is a must for any real development for alot of reasons.
More generally anyone who refuses to learn is in the wrong field

[astral epoch]

Honestly most people I knew at Uni for game dev stuff were in the wrong field.

Hate to sound elitist but a shocking amount just didn't grasp some basic principles about their own fields.

[placid parcel]

Could someone help guide me. I created a mouse sens slider and it works fine however, I want it to save the position the players put it in instead of going back to the default value I have the slider at

[tranquil field]

anyone know how i get the orange outlined box?

[desert juniper]

minus

(alias is -)

[tranquil field]

ty

if someone thinks they can help me with this, can you pm me so we can talk about it? i need help.

i basically cant figure out how to do any of that in the picture

[modern skiff]

Percentage would be... current value float / max value float

[tranquil field]

what exactly do i put in to get "get health bar percent" and "get energy bar percent"

[modern skiff]

You need 2 float variables... "Current Value" and "Max Value"... divide the floats and plug the return value into the return float on that function

[tranquil field]

im still confused.... im new to this stuff and that is not exactly what it says on the tutorial im looking off of... than again it says nothing about how to get the percents anywhere on it, im just confused on everything.

[modern skiff]

this is an example of how you can do it through your bind... however it runs every tick, later on down the road in your project after you have a better grasp on how to do things you would want to switch it to only update using rep notifies

[tranquil field]

no like i dont know how to get the Get health bar percent node...

[modern skiff]

you will not have a setup like the one i shared though because your project is not the same

[tranquil field]

literally the 1st thing you have in that picture

[trim matrix]

Simple question, at some point (in the construction script) I create a new component (a box collision)
How do I get an Event Begin Overlap Node of that component in my event graph? It's not in the component list because it isn't created immediately

[modern skiff]

if i am understanding you, you need help creating the binding... select your progress bar, then under details there is a bind option under "Progress"

[tranquil field]

yeah that helped, ty

[modern skiff]

np

[tranquil field]

and 1 more thing, what is this node called, if u know

sorry lol im new to ue5

[errant cliff]

Hey guys im trying to enable the debugging mode to check AI perception but the key I set in my project settings doesnt work.... it only works in simulation mode but i cant switch from one mode to another to get the sight mode :/ help please

[finite island]

any idea on how do i create a level select menu

so far i have this, not sure how to add button to level1 and level 2 selection

[tawdry surge]

@tranquil field that's a reference to a float variable named health.
The target is the owner of the variable

[errant cliff]

Even enabling the mode through the ingame console doesnt work what the hell

[tranquil field]

ty

[errant cliff]

ok working now no clue what i did

[tawdry surge]

@finite island you can call "open level" using the "on pressed" or "on clicked" event for the button

[finite island]

i figured i need to wrap it in a button first

then add event

[tranquil field]

is someone open for me to discord call them (neither of us have to talk i just have to screen share you to explain my problem) and have you try to help me? it shouldnt be too complicated, im new to ue5 and building a simple game for a assignment

[covert arrow]

does anyone know a cleaner way of doing this. Basically I'm inputting this select with surface types of my game and supplying the correct sound based on a get() node from the array of sounds.

[thin panther]

use the index of the enum as your index?

but first chek if that index is within the range

[tight schooner]

Map variable?

[thin panther]

or that too

forgot they exist

[covert arrow]

never used a map variable can you show an example?

[covert arrow]

it does look cleaner thanks

[tight schooner]

There's probably a Mathew Wadstein video, lol

You know how you can change a variable type to an array? Map is one of the other options

It associates one data type with another

[covert arrow]

yea I think I can figure it out.

[tight schooner]

Use your enum as the... Thing that goes on the left lol

[covert arrow]

It associated it with a integer type

[tight schooner]

And then you can associate a sound cue obj reference or whatever with each enum

And with that variable on the graph, I think you use the find node?

It's array-like but not an array in the sense that there are no indexes

[bold phoenix]

hi ! Is there a way to move an element in an array without using "remove" then "insert" nodes ?

[covert arrow]

is this what you meant? Not sure if I did it correctly.

[trim matrix]

How do I rename a component I create in the construction script to give it a custom name?

[tight schooner]

Rather than use an integer in the map, use your surface type enum

[covert arrow]

ah

[covert arrow]

thanks okay

[tight schooner]

I don't think you can, at least not in BP. You can give it a component tag though if you want to give it some metadata.

[covert arrow]

hey do you know how I can input the surface type on the find node? @tight schooner

oh nvm

my function input is the surface type

like this @tight schooner

[true valve]

Can you use MoveComponentTo with AttachActorToCompo?

[tight schooner]

Yeah I think that should work @covert arrow

[true valve]

To smoothly attach an actor from one socket to another.

[covert arrow]

it works perfectly. Thank you it looks much cleaner.

[tranquil field]

i need a help. i can get it so when i jump my stamina runs out (on a stamina bar i made) and when i hit the key "f" my health goes down but this is what i need help with.

destroying my character when health goes to 0

Not letting me jump any more when stamina is at 0. anyone know how to do that?

[tight schooner]

Generally speaking, check your stamina before jumping. Check your health after taking damage to see if you're outta HP.

You can use a > node

And plug the boolean output into a branch node

[tranquil field]

this is the code my teacher gave for killing the player at 0 health but it doesnt seem to work

i copied that exactly and purposefully got to 0 health and i didnt 'die'

[tight schooner]

Hmm yeah dunno. The graph makes sense to me. Do some debugging with print nodes and/or breakpoints to see if damage events are even occurring

[tranquil field]

cause i have a healt hbar that shows my health in real time and when it goes to 0 nothing happens

[tight schooner]

What if you disconnect the false exec pin that goes to the Set Invincible node?

Idk I'm just stabbing in the dark here

Sorry I can't help

Based on your screenshot it seems like it should work

[tranquil field]

as u can see my health is set to 0 rn but my character is still there. and sry its so dark, thats how my game is supposed to look lol

[crude isle]

How can I set focus on all buttons not just one

so I dont have to click multiple times sometimes for a button to work

I want every button to be focused on and able to use it by only clicking once

[cyan bone]

I have to check the the distance between a group of actors and my line.
For that i need a for loop that checks all locations distances.
Now one thing im doing in all my functions, i need to start with a Variable float that is like 99999, so that its not 0, and from there if it is lower, i set the new lower value.
Is there a simpler way to do this? I feel like im doing some bad practice here.

[zealous moth]

@cyan bone makes sense to me.

[cyan bone]

So its all good? 9999 ? 😆

[zealous moth]

@crude isle put them all under 1 ummg parent and focus it?

[tranquil field]

can someone tell me why when my player health is <= 0.1 my actor doesnt get destroyed?

[zealous moth]

@cyan bone I did the same awhile back. I dunno of any better alternatives

@tranquil field use toggle breakpoint and see

[tranquil field]

where

[zealous moth]

In that graph

Press f10 to advance

During play

[tranquil field]

btw im new to ue5 i barely know anything lol. my professor just threw us in and said "make a game" with no prior teaching

so press play then press f10?

[zealous moth]

Make pong

Nah right click a node

And select toggle breakpoint

Same as in vs

[tranquil field]

now what nodes and how do i check if it worked

[zealous moth]

The first one red

When you receive damage you will be prompted to the graph

And you can follow stepwise events

[tranquil field]

im "taking damage" but not being "prompted to the graph"

[zealous moth]

Right click it

[tranquil field]

this is the variable i use for taking said damage

[zealous moth]

I am not at computer can anyone show him?

[modern skiff]

i would recommend to start here
https://www.youtube.com/c/MathewWadsteinTutorials/videos

[tight schooner]

Me neither lol

[tranquil field]

this is an assignment...... due today

[tranquil field]

what should happen when i right click it, if u know

[zealous moth]

Man I don't miss school and their arbitrary nonsense

[tight schooner]

Can you call Event AnyDamage from your "F" pressed event?

[thin panther]

left it a bit late didnt ya?

[tight schooner]

You got all your logic on the former but not on the latter

[tranquil field]

been working on this for a week now lol

[trim matrix]

Any idea why my overlap events would only work once and then stop completely until I cancel and load into the map the actor again?

[thin panther]

ah fair enough

[trim matrix]

It's honestly bizarre

[thin panther]

that is bizzare

do once node?

[trim matrix]

No it's a component begin overlap node

I press play, it works, then I press exit and play again, it stops working

[thin panther]

yeah do you have any do onces after

[tranquil field]

i have a block that follows me, stamina and health bars (almost) animations, a start and pause menu, and a win screen basically everything a "game needs"

[thin panther]

wait waaat

[trim matrix]

I don't

[thin panther]

thats weird

[trim matrix]

The only thing I have is that the collision box in question is being "set" in the construction script

But that shouldn't be an issue shouldn't it?

[paper gate]

Any branch u using ?

[trim matrix]

Nope

[paper gate]

Send ss

[trim matrix]

My construction script is hella complicated

[zealous moth]

Did you mix up you feed and seed with chuck's?

[trim matrix]

What?

[sudden nimbus]

did you know that construction scripts run both at editor time and spawn time? And that since they all run in the first frame that their corresponding actors are present in, they all contribute to the "infinite loop" detection of blueprint?

meaning if you use enough of them, you can crash your game even though each actor individually is only a small slice of the overall work happening on that first frame?

[tight schooner]

@tranquil fieldok here's the problem. You got two events. One of them decreases the hitpoints. The other one checks for invincibility, decreases the hitpoints, checks for 0HP, and manages death and invincibility. There are a lot of ways to solve this problem but here's something you can use.

Make a third, custom event. Call it TakeDamage or whatever. Give this event 1 input: a float named Damage.

Take all the nodes you have attached to Event AnyDamage in your screenshot, and then move it to your new, custom TakeDamage event. And now you should have an event that handles all the damage-related stuff that you can call from anywhere else in the graph.

In your "F pressed" event, call this new TakeDamage event. Likewise in your Event AnyDamage event, call this new TakeDamage event.

[tranquil field]

having someone help me with it, ill send a ss after with the code and see what yall think lol

[desert juniper]

👋 long time no see
and TIL. good to know lol

[sudden nimbus]

hiya!!!

[empty bay]

Hey can anyone help me figure out how to make a stopwatch system that can compare your current time with the best time and save a new best time? Most of the functionality seems pretty simple with my main issue being I need to save the best time of multiple levels. Do I use arrays for this? If so how exactly would that work?

[sudden nimbus]

Yeah, compartmentalizing logic, whether into custom events or functions, is always a good call :-D

[sudden nimbus]

saving data across multiple levels means GameInstance or a GameInstance subsystem

as opposed to GameMode, or level blueprint / actor level storage

if you need to persist it across multiple runs of your game, then that's the game save system, and there is the built-in mechanisms and plenty of third party solutions that are easier to work with directly from blueprint

[empty bay]

Well I understand the logic behind saving one best time. I'm having a problem wrapping my head around saving multiple best times for each level

I assume I want to use an float array but I'm not sure how to implement it

That's what I'm looking for advice on

[errant cliff]

hey I have a weird glitch where sometimes my AI is going to do baby steps and not walk until they reach me

most of the time it works but if it loose my sight for a bit it acts weird and only do small increment of movement

[sudden nimbus]

behavior tree? use Observe Blackboard Value-- it's baby steps because that's where the target of the move was when the move operation started

[errant cliff]

can you rephrase the second part ahah

[sudden nimbus]

observe Blackboard value tells it to continuously update the target

[errant cliff]

actually i cant replicate the behavior

observe Blackboard value - where is this

[sudden nimbus]

it's a setting on MoveTo

[trim matrix]

There's definately something wrong with construction scripts and collisions

I tested it in UE5 as well and the problem still remains

The collision are inconsistent as hell, it works 3/10

[sudden nimbus]

more detail and I'm in

[errant cliff]

ok got it now im reading

[errant cliff]

i dont think it will fix it thouhg. even when i stop moving it does baby steps

[sudden nimbus]

(reads back on soldierofdooms thread)

I think I have an idea here-- show some blueprint for these overlap events

[trim matrix]

I'm uploading a vid

[trim matrix]

So a bit of context on this: the yellow rectangle is a box collision component that I generate and set (transform and box boundaries) in the construction script - the white cube in the back is just another actor that has no construction scripts at all and just destroys what it collides with
As you can see the first yellow rectangle SHOULD react every time the ball passes through but it works like 2-3 times out of 10 attempts, the white box in the back like I said is just a "catch all" so I could spawn multiple balls

The expected behavior is: when the ball passes through the yellow collision it should get destroyed every single time

Since it is a normal box collision component set to overlapalldynamic with a OnComponentBeginOverlap event

[errant cliff]

thanks @sudden nimbus even though i cant replicate, i like your observer idea and maybe it helped!

[sudden nimbus]

observing blackboard value prevents the moveto from finishing even as the target changes

necessarily there is a delay between movetos

[errant cliff]

yeah but my problem I think is that it sets very close position to go to even though I set a 1K radius

like it ignore this radius

oh wait radius is even lower. its 5

[sudden nimbus]

make that higher

[errant cliff]

so it should get very close to me

[trim matrix]

@sudden nimbus I sent a video up there

[sudden nimbus]

the acceptable range radius is not always achievable, and there is a timeout value too

more than likely, the moveto is failing to achieve the acceptable range

so its timing out

[errant cliff]

so my tree radius is at 5 for moveto funcs

my task to find navigable path

has a radius of 1K

which one should I change?

[trim matrix]

also @sudden nimbus https://prnt.sc/5KjRD83FQSkw this is how that yellow box is constructed in the construction script

the reason it is in the construction script is because the map is dynamic and so all the walls / boundaries are relative to the selected size

[errant cliff]

sorry lol

i used unreal for 48 hours still not sure where to look sometimes

[trim matrix]

Anyways I've posted everything relevant hopefully someone can check it out

[errant cliff]

wishing you luck. ill stop bothering @sudden nimbus soon lol

[trim matrix]

you ain't bothering lol

[errant cliff]

going to sleep good luck!

and thanks again @sudden nimbus

[sudden nimbus]

np

[trim matrix]

Figured it out btw

@sudden nimbus you said you were in so what's the deal?

[sudden nimbus]

oh yeah i shouldve watched your video

make the yellow box wider

see if its more reliable

physics checks can be missed 😕

[trim matrix]

you're on the money

[sudden nimbus]

there is a flag

[trim matrix]

In my blueprint functions fuckery I was passing a NEGATIVE number on my X and Y box extent

[sudden nimbus]

continuous something or other

[trim matrix]

And that makes it super inconsistent

Once I fixed it it works 101% of the times

[sudden nimbus]

if you need the box to be more thin you might try

but it has a cost so

only if really needed

[brazen stirrup]

this is what ive got for switching between two collisions, but

it makes them stuck in eachother for some reason, and when my character jumps, they go through the floor

any thoughts?

[trim matrix]

And now the negate pin stops working for some bizarre reason

Am I too tired or shouldn't a number turn positive if I negate a negative?

-10 * -1 = 10

[sudden nimbus]

that is how math works

[trim matrix]

apprently not in unreal

[sudden nimbus]

it probably (well, definitely) works that way in unreal, im leaning towards "tired"

dont trust the debugger, my friend

if in doubt, print it

[trim matrix]

also isn't it possible to create an unsigned int variable

or an unsigned float even

[sudden nimbus]

not in blueprint, no

[trim matrix]

not even a struct?

[sudden nimbus]

Not a blueprint struct asset no

[trim matrix]

Also why can't I see the variables values anymore when I hover over the pins

in play

[brazen stirrup]

So, can anyone answer my question pls?

[trim matrix]

I swear to god unreal is trolling me

[sudden nimbus]

it's only expected to reliably work when paused on a breakpoint, though there are certain tricks used to make those work regardless in many cases. This is the debugger, and the blueprint debugger is not 100% reliable

[trim matrix]

I have a node that does the exact same thing and one of them is returning a negative variable

[brazen stirrup]

How to switch between two capsule components ?

I’ve searched everywhere and couldn’t find an answer

[sudden nimbus]

why

[brazen stirrup]

Well, I have a volleyball dive animation

But it doesn’t have root motion

So I’m trying to work around that

[sudden nimbus]

why not change the radius and height of the 1 capsule

[brazen stirrup]

Well, I’m trying to make the character fall

Hmmm actually

Maybe I’ll give that a try

[sudden nimbus]

yeah I don't think swapping capsule components will help you simulate falling no matter what

[brazen stirrup]

But can I have the ball bounce off his hands ?

[sudden nimbus]

I don't know, the information required to answer that question has definitely not yet been provided.

[brazen stirrup]

Ah ok, I’ll look into it more haha

[sudden nimbus]

I suppose if the hand bones had some kind of capsule or sphere collision component attached then one could get a ball actor to bounce off of the hands moving, which are moving based on a predefined animation, but I doubt that's the standard way to implement a volleyball game

you might use those collision components to listen for the first collision, and then act on the ball accordingly so that you don't end up affecting the ball more than you want, since hands are not spheres

Still looking for assistance on this if anyone is willing to help. For clarification I need to save a different "Best Time" for each level.

[thin panther]

Do you need to save multiple bests for say a leaderboard

Cause if not you coukd just comparr the saved best time with current time..and if current time is better o verwrite it

Otherwise id have an array if a fixed length, if it isnt full add new times, otherwise lool through and see if the lowest best in the array is better or worse than current time

[empty bay]

Not really looking for multiple times for each level and I understand overwrite a new best time and saving it. My problem is saving a different best time for each level. So level 1 best time would be 02:22.22 while level 2's best time could be 01:23.54

[thin panther]

I would make an array of level data

Each level has data that needs to be saved, whether it be whether the level is unlocked etc.

So in there just have a variable for best time

1 index fkr each level

[empty bay]

So how would I do that? Which blueprint would I put it in? What kind of variables do I use? Is there a source where I can read more about this?

[thin panther]

An array of whatever you wanna use to store time

[pulsar lotus]

Hey could I please get some help. I'm trying to aim my crosshairs in game but the debug sphere stays in one place. any help would be appreciated. thank you.

[thin panther]

Probably a float

Since it requires between gameplay then as said previously a save game would be ideal

[empty bay]

Something like this?

[thin panther]

You are probably rotating the cylinder in place

[empty bay]

1 array for each level?

[thin panther]

Thats a float array yes

Not 1 array for each level

1 indec for each level

You dint need multiple times for each level

[empty bay]

Sorry yeah inex

[pulsar lotus]

could you please elaborate more. im a beta when it comes to this stuff

[thin panther]

I read ur bp wring sorry

How often are you calling crosshair function

[pulsar lotus]

once, just to get the hit result

[thin panther]

Then you are never redrawing the sphere so it wont move

[cedar cave]

Can anyone help me with my blueprint, i want my character to play an animation when interacting, should i do that in the state machine or somewhere else?

[thin panther]

If you only call it once, its only gonna do it once

[pulsar lotus]

ok thank you very much

[thin panther]

#animation

[cedar cave]

Thanks

[thin panther]

Np

[pulsar lotus]

wait one more question. what if its an event tick

[thin panther]

That woukd not call once so would do what you need it to

Make sure you only draw ur debug object for a frame though

[pulsar lotus]

Alright now thank you

😄

[empty bay]

So how would I go about comparing the two?

[thin panther]

Get whatever level index you are on, and compare the times

You will need a way to know which levels are which index

[empty bay]

I'm sorry but how?

[thin panther]

Could maybe use a map or a data table

I will leave the rest for you to figure out

Use either one of those to link the indexes with the levels

Then use that index to get your time and compare it to the current

[empty bay]

Alright

https://youtu.be/cf25ekO-AFs This is what I should be learning?

[thin panther]

Again either that or a data table

[empty bay]

got it thank you

i know python and simple c++, wanted to learn blueprint stuff to a point where i feel liberty on doing what is on my mind or something

[rapid ginkgo]

For overall thing, that's great! But if you want to get in depth there are better alternatives.

[rocky ore]

i would like to, could you point me to somewhere? so i can go for these after this one

[rapid ginkgo]

Dev squad Aka virtus has a blueprint small course on YouTube. It mainly focuses on the basic and bit advanced of some things what you need for game dev. Each video has one topic so it's easy to follow on.

How do I put multiple children under a widget?

am I supposed to be using canvas panels?

Any multichild container works

Canvas has its uses but is not my personal go-to for every widget

Usually try to keep it to one canvas and add modules to that

Hi, Can I ask you 4 help with respawn system in my arcade racer game ( 4.27.2 ) ? I am rebuilding the respawn system right now, at the beginning I was using the destroy -> to -> respawn logic, but that caused a lot of problems, because engine tends to rename spawned actors ( player car ) so all the references were lost after the respawn was done. Yesterday I've rebuilt the system into teleport after the car is overlapped by obstacle ( or drives out of the track ) then the car succesfully teleports to checkpoint, but THE PROBLEM is: it always teleports to first checkpoint in group, not to the last cleared

When I drive through each checkpoint, I recieve a clearment confirmation, which I've set to print string of "RESPAWN LOCATION SET", but the respawn location won't update

How can I make the Checkpoint update the location ?

the desired transform location

[spark steppe]

that screenshot is unreadable

[wicked osprey]

Guys, can you please tell me why I don't choose objects on the map on the LMB, but just fly? Maybe I accidentally clamped some combination of keys

Does anyone know how to use the "importance sample" node? I want to spawn an actor by the alpha / red channel of a texture, but it's unclear how to get it to work 😦

[trim matrix]

I am trying to recreate the fire waves from this video: https://youtu.be/ZYz2mbbW83Q?t=131 but i have no idea how to make those lines snap to the ground in run time.

[tight schooner]

Maybe a good #visual-fx or #niagara question. A material that deforms to a heightmap texture? A Niagara ribbon emitter that line-traces to find the ground? Idk

[serene bramble]

Does umg have some kind of word wrapping? To fix this

Also, every time I build my lighting I get a warning:

⚠️ No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene's quality and lighting build times.

[elfin wolf]

add an importance volume

like you'd add a cube

but have it around your level

Hi, I need a function that stores the desired teleport location ( NOT the "spawn location" ) and after the actor overlaps the collision BP, that fires the respawn event ( I don't want to use the destroy function )

First I've created the checkpoint blueprint, that is cleared by actor once actor drives through it

[icy dragon]

Yes.

[serene bramble]

[past hazel]

how to correctly calculate the Locomotion Angle so that the animation of the character's legs is correct in all directions?

[fair oak]

how do i get the player location? i think i'm doing it horribly wrong

[weary flame]

Notice the grey object pin on cast. You are not casting anything. You need to get a reference to your third person.

But for what you are doing you don't need to cast, just use the controlled pawn

[fair oak]

ah thanks

[twin robin]

How do you think Elden Ring lights up the area around the player when it's dark?

A point light in the player character bp doesnt seem to cut it, getting unwanted specular highlights & such in the environment

[icy dragon]

tweaks these settings in the light

actually just soft source radius will do it

maybe to like 100

How do I tie an actor object reference to a select (probably an enum)? I want to change the class that gets spit out based on the actor that comes. I don't want to make 15 million branches.

[dreamy yacht]

Hi! Anyone can help me? I need to create logic, that stores the location of last checkpoint that is cleared by PlayerCharacter and then if I keep on playing and overlap the trigger, the trigger teleports me back to this location

Anyone?

I don't want to use destroy and spawn transform

[fair oak]

do you know how to split the vector coordinates with wich node?

[tight schooner]

Right click on vector pin, "break"

[fair oak]

i want it to check if the player moved on the grid to a different spot any idea how to check for that i would check if the location is the same as a previous saved one but idk how i get the "previous saved one" lol

[tight schooner]

I don't know anything about your movement system, so generally speaking

the way you save data is to store it into a variable

so whenever the player moves, you can store it into a vector variable

and then you can do comparisons

[fair oak]

but how do i check if the player moved

i use the normal third person template btw

[icy dragon]

Check if velocity != 0

[fair oak]

huh wdym i'm such a beginner lol

so i know what != is but wdym with velocity

[elfin wolf]

in the checkpoint bp, make a vector variable, set it to instance editable. In the characterbp make a vector variable called respawn location. when there is a collision event with the checkpoint, in the checkpoint bp get the hit actor, and cast it to player, set the players respawn location variable to the checkpoints variable you made at the start

[icy dragon]

Velocity in general?

[fair oak]

yes so i think its maybe current movement idk but idk wich node or yeah idk in general

[twin robin]

Thank you, trying it out. Looks ok, do you think a post process effect centered around the player could work as an alternative to using a light?

[elfin wolf]

not sure, idk if it would look great though

[dreamy yacht]

yeah use on begin overlap

And as the event firing actor will be another actor, you know that ? The actor that fires the event will be the map-out-of-bounds-collision-box

[modest monolith]

Hello guys, I'm making an endless runner and I have a buff where when I touch a mesh, the mesh checks if I have the buff and the mesh gets destroyed and lose collisions. The problem is that when I touch the mesh I don't die but still I get stopped for a millisecond making my player lose movement speed or in worst cases change direction (Bad thing since it's a lane based endless runner ) how can I fix it?

[elfin wolf]

the actor that fires the event will be the checkpoint

[errant cliff]

blueprints are so cool

but the Ai tree stuff is headaches, its so complicated

[spark steppe]

its not. once you get used to it you'll like it

[errant cliff]

Ok I hope so. Ive been using unreal for 3 days only so still have time i guess

did anyone take training they'd recommend?

[spark steppe]

https://learn.unrealengine.com you could look at those courses

[errant cliff]

Some of these assume you're either a genius or like you made the tool yourself lol

[gentle urchin]

Wait 'till you get to the actually complicated parts

[spark steppe]

for blueprint nodes general explanation you can search for MathewW videos on youtube

[errant cliff]

Which ones ahah

[errant cliff]

ok thanks!

[errant cliff]

dont forget to add a jump key lol

[modest monolith]

XD

[tight schooner]

is the collision set to "block"? Maybe you want overlaps instead

[modest monolith]

If I put on overlap then it won't block when i'm without the buff

basically without buff should me a common obstacle where I bump into and ide

die

but with the buff

I can break it

but without affecting my location or speed

the problem is that this calculation happens when I hit the mesh and the time is too short for the game to elaborate i think so I still get that millisecond of block

and stop

[dreamy yacht]

No, I mean - the actor that fires the location change ( teleport to location of last cleared checkpoint ) is other actor named "Overlap Kill Volume"

[tight schooner]

@modest monolith yeah I see the issue. Can't think of an elegant solution rn. Maybe an event dispatcher that all the blockers are bound to; they change collision modes whenever the powerup is activated or expired, like Super Mario.

but yeah I see the issue where collision occurs, and then a post-collision BP event is triggered means there's still collision for a frame

[modest monolith]

I tried to do like when you get the buff - get all actor from class (obstacle) - set overlap only

but i think it's waaaay to heavy and it won't work with obstacles spawned right after

so it's not an healthy solution i guess

[tight schooner]

yeah, there might have to be some manager that stores or otherwise gets the buff state on demand. If it's an endless runner then you're spawning obstacles dynamically so there's necessarily a manager...

it depends on your architecture / your preferences where the buff state is stored

but wherever it is, it should be somewhere easy to get

so that newly spawned obstacles can read it

and bind to a dispatcher that informs of changes

it shouldn't be heavy unless you have several hundred spawned at any given time

[elfin wolf]

yes, the overlap kill volume can cast to the player and teleport it to the teleport location variable i told you to store in the player

[final storm]

https://gyazo.com/62a7bbb117862b3fac0593e44030455a
does anyone know how i can fix this? :(

[modest monolith]

I usually store my buffs on my character

yeah I have a game manager and also an obstacle spawner

[tight schooner]

@modest monolith If you actually have hundreds of obstacles in the world at any time and you want to limit cost, a simpler, arguably less best-practice way I guess is to periodically make the player do a SphereOverlapActors, like once every two seconds or whatever, and update the obstaces around it

those are just my top-of-head ideas

[modest monolith]

Uuuuh seems a juicy idea

[tight schooner]

I suppose a manager could do it too. Sphere overlap actors with location as Get Player Pawn --> Get Actor Location

[modest monolith]

so basically a sphere with event begin overlap - cast to destructible mesh - is buffed? - set collision to query only

[tight schooner]

I guess a persistent sphere collision component could work too

[fair oak]

i want to trigger an interface event outside the third person actor to another actor but it does nothing the first one does work but not outside the actor (the last two screenshots)

[tight schooner]

I was just thinking of the single-use node, SphereOverlapActors

[modest monolith]

but what about if my buff ends while overlapping a destructible mesh ? the mesh will remain destructible

should I use an event tick?

or maybe call event on timer ( i don't remember the name) at every 0.1 sec

[tight schooner]

I guess whenever the buff state changes, you manually do the sphere check and update the obstacles on that frame

[modest monolith]

cheapest

[tight schooner]

if it's a persistent collision component attached to the player, I think there are nodes for Get Overlapping Actors etc.

[tight schooner]

If actor 1 is sending an interface message to actor 2, the interface message node has a mailing envelope icon over it. You need to use the node that has that icon on it

[modest monolith]

With this one I don't need to create a sphere collision apparently.. am i wrong ?

[fair oak]

i know i had this in my other project from a tutorial but i just cant get this icon

[tight schooner]

@modest monolith You're not wrong. It's two different ways of doing it... a persistent sphere collision component on the BP, or SphereOverlapActors on demand.

[cyan bone]

I need to animate a waving red flag 🚩
I have 3 options that i know of:
1- Put a texture in it, and rinterp left and right to simulate the wind.
2- Use sprites that change giving it the illusion that wind is waving it.
3- Animate it in the skeletal mesh (never did this).
Which one is the cheapest for performance?

[modest monolith]

Am i close ? haha

[timid orbit]

uncheck context sensitive then look for Move Grid (message)

[earnest tangle]

Unless you plan to have hundreds of them at the same time the cost of animating it is negligible using any of those methods

[tight schooner]

Cheapest way I think is doing it in the material graph via World Position Offset. For example scrolling a noise texture to produce the vertex offset values. Never did it myself so dunno the ins & outs of making that look nice. That would be an all-GPU approach

[cyan bone]

I will have hundreds yes

[fair oak]

sorry where do i uncheck this

[earnest tangle]

seanny's suggestion would probably be a good one to try then

[modest monolith]

@tight schooner should I put this in the event tick ?

even tho i'm sure there's something else to change

[timid orbit]

when you right-click on a graph to get a node

[cyan bone]

Never heard of this. Is there a specific keyword for this technique? material graph via world position offset.

[errant cliff]

wow EQS are insane

[tight schooner]

Depends. If the sphere is large enough and the character doesn't move so fast that it covers the radius of the sphere in under 1 second, you could probably get away with doing it once per second e.g.

[modest monolith]

Well I can just put the sphere very big isn't it ?

[fair oak]

thanks it woorks :)

[cyan bone]

So you mean like changing the world position of the material?

[tight schooner]

uhh... vertex shader? I actually don't know offhand 😅
World Position Offset is the Unreal Engine jargon. You basically offset the vertices of a model with math in the material graph.

[timid orbit]

👌

[cyan bone]

So i change the position of the material via creating dynamic material? I remember doing something like that in the past. It was hard

[tight schooner]

@cyan boneIt doesn't have to be a dynamic material unless you want parameters. It could be a static material, but with a Time node driving the panning of a texture. Kinda getting into #graphics territory here

[faint pasture]

You don't need to create a dynamic material.

@cyan bone Same idea as wind and foliage, just different motion. Look that up and you'll find writeups on it.

[cyan bone]

Oh i see. The scalar material? Something like that? Sorry im just shooting

[faint pasture]

A dynamic material is one you update parameters on while it's in use. Has nothing to do with motion.

[cyan bone]

https://www.youtube.com/watch?v=PXK4tvlSsuo
So something like this will do. This is cheap in performance?

[modest monolith]

@tight schooner which object type should I put here ?

[indigo quest]

Is there an event that fires when skeletal mesh LOD changes?

[tight schooner]

well, skipping to the WPO part of the video (toward the end), he's using SimpleGrassWind, which is something I'm not familiar with. But supposing it just adds some generic wobble to the mesh, and he scales the effect by one of the UV channels (to keep the base of the plant rooted), and plugging that into World Position Offset... that's in the ballpark of what I was thinking. GPU perf impact will scale by the quantity of vertices I think??

[tight schooner]

pull the Object Type pin out and "Make"

[lyric glade]

is this gonna make sure that if there is no true outcome the gate will close?

[cyan bone]

So the difference is that you wouldnt necessarily need to use the SimpleGrassWind. And this will be cheaper than a rinterp.

[modest monolith]

Ohhh perfect.. I leave it at world static ?

[modest monolith]

Okay .. the whole thing seems to work!

but sometimes it still doesn't

like when I take the power up and then hit the mesh right after

also i noticed that when I hit the mesh from the side I still get collision and get pushed back a little bit

[errant cliff]

Hey i duplicated a AI dude and im trying to connect a new AIC, however im getting an error and also i have these white arrows showing up with the new test but not with the previous setup. any thoughts?

[modest monolith]

This is my setup at the moment @tight schooner

[modest monolith]

Try to CTRL + W the cast below and try to call the function from the as AIC Merchant Character in the cast

[errant cliff]

checking thanks

[errant cliff]

wait what lol

[errant cliff]

if i replace to previous node it works but i want to use new character not previous one

my AIC is not calling anything though

[modest monolith]

I didn't follow all your procedure but if you want the cast above to looks like the one below try to duplicate the one below with CTRL+ W

[errant cliff]

ohh

but why isnt it working by search then

[modest monolith]

and call update target actor key from the blue node of the cast

[errant cliff]

ctrl W doesnt do anything

[modest monolith]

Ah I noticed

[serene pike]

Bit of an issue, I'm following a keypad tutorial and at point point something is different to what I'm following:
video : ||https://youtu.be/m3DQmi2LUOE?t=985||
Is this just because of an icon change since making the video or have I regrettably gone wrong somewhere?

[modest monolith]

It should duplicate but I noticed they are not the same so no it won't work anyway

[errant cliff]

yeah exactly but im not sure why

everything else should be done, new AIC connected to new character

why are these bloody exec arrows sjowing damn it

[modest monolith]

XD

[zinc spear]

anyone know how i can stop my character from sliding down slopes like this?

[modest monolith]

I don't understand why putting event tick - setting meshes query only and with pawn overlap only

sphere radius 100

still I receive that problem

It is smaller

but it's still there @tight schooner

[serene pike]

did you change the walkable floor angle?

[modest monolith]

https://tenor.com/view/staiy-twitch-gaming-shocked-tiktok-gif-17487184

[zinc spear]

its set to 50, i tried maxing it but nothing changed

[tight schooner]

Call it manually immediately after getting the powerup and changing the state. You want all obstacles nearby to be notified on that frame

[tight schooner]

You need to use the array element on the loop body

[errant cliff]

figured it out if anyone is curious, just needed to convert as pure cast.. I am assuming its like forcing a cast

[serene pike]

anyone have an answer for this? Very simple issue, just hoping someone will remember

[modest monolith]

I think it doesn't work because i'm actually doing nothing lol

I mean.. I think i'm not telling the game to change collision to the meshes inside the sphere

[tight schooner]

You're still not using the array element. You're getting an array of nearby meshes but then not doing anything with that array

[modest monolith]

Probably is just a visual problem or maybe different version of unreal ?

[modest monolith]

How can I fix that ? where should I put the array element ? I don't see where to link it

[tight schooner]

@modest monolith loop body pin on the For Each Loop node

[serene pike]

it'll most likely be a different version, its just that I've followed it fine as far as I'm aware but I can't follow the video any more, assuming it may be this discrepancy

[modest monolith]

I have to do a second ? for each loop node ?

XDDD

I'm not understanding

how can I put array element on the same node where it is ?

[tight schooner]

@modest monolith in your screenshot there is a For Each Loop node. It has an output called Array Element

[modest monolith]

Yes

[tight schooner]

That output is the "each"

You want to do something with each item in the array

Right? Otherwise you're getting that array for no reason

The array element pin is "each item"

In the loop body, you want to manipulate the array element

That's the whole idea behind a foreachloop

[modest monolith]

Okay but I can't put the "each item" to the collision modifiers

[tight schooner]

The array element output should be the actor class you filtered for. Drag it out and then do your stuff, like set collision disabled

You might need to get the static mesh from it first

[modest monolith]

If I put set collision disable I won't be able to hit and destroy the mesh

[tight schooner]

Array element -> get static mesh -> set collision

[modest monolith]

Tried already

[tight schooner]

When you mouse over the array output on the Sphere Overlap Actors node, what data type is it? Actor?

[tight schooner]

ok, I thought it would output the thing you set in the actor class filter, but instead it's outputting generic actor object references

[modest monolith]

Yes

Big mess

[tight schooner]

For Each Loop --> loop body --> take the array element and Cast To BP Destructible Whatevers --> get static mesh --> set collision

[winged totem]

Hi there, i'm not sure where i should post this but, Regarding import French language as localization .PO file in Localization dashboard, there are some accent characters that UE4 importas as "?" instead french accent. any clue to solve this?

[gentle urchin]

Could prob get the mesh component from the actor

And set collision that way

[modest monolith]

@tight schooner Like this?

[tight schooner]

yeah, I guess you don't need to cast if you're not doing something class-specific

[modest monolith]

or shall I cast after the branch ? maybe is better

[tight schooner]

in any case what you have in the screenshot should work

[modest monolith]

probably is better to cast after the branch ? at least I cast only if I have the buff and I save in prestations

am I wrong ?

[tight schooner]

casting isn't expensive contrary to popular belief... it shouldn't matter that much. But don't you want to alter the collision when the buff runs out too?

[modest monolith]

Oh yeah true.

Updates: It doesn't work

[tight schooner]

[modest monolith]

Why something so simple give me so many problems omg

[tight schooner]

time to debug with print nodes and breakpoints and maybe even debug shapes

figure out if every part of your thing is working

is Sphere Overlap Actors getting actors? How many? Is the cast succeeding? etc.

[modest monolith]

Maybe this is creating problems ?

Why is not filtering classes ? I've put that has to detect only destructible meshes isn't it ?

[sage magnet]

Hey hey people,
I have a question regarding timer handlers.
Let's say I have a timer that shoots a function every 30 seconds.
What happens if I clear that timer handler 17 seconds in? Will the function still be used or no?

[tight schooner]

by clear do you mean use the node, Clear and Invalidate Timer by Handle? (https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Utilities/Time/ClearandInvalidateTimerbyHandle/)

I think that aborts the countdown

[sage magnet]

Yes. So I wonder if I do that at 17 seconds in, would the function fire at 17 seconds or not at all?

[tight schooner]

it doesn't call the function at all once you clear it

[sage magnet]

ok, thanks

[modest monolith]

I guess enough burning out for today

[modest monolith]

Thank you for the help!

[vocal kestrel]

Howdy, this is an odd question, but i added the third person starter pack to a project, and i can run around with the character, but the BP_ThirdPersonCharacter's event graph is totallly empty. I uhhh.... don't know where the code for this thing is, cuz it's usually here. Did the structure of the thirdpersonstarter character change alot from ue4-5?

i'm lookin at the doc page for it i am not seein' what it's showin'

[brazen leaf]

Hi all I'm beating my head against a wall.
I want to have an actor use an enum variable I assign to give itself an actor component in Begin Play. Breakpoint and Printing show that its hitting my code and getting a valid thing but I don't see the component anywhere in the scene on Play and any effects it should have are not happening.
In the pic, I have an array of Tasks Im looping through and trying Add BP Task Class (which is an actor component) and then constructing it from a data table.

[zinc spear]

any ideas?

[maiden wadi]

I doubt that they even touched it. Are you sure you didn't add a C++ Third Person Starter pack instead of a BP one? The C++ classes would only need a BP for setting values.

[maiden wadi]

Wouldn't expect that to do much. You're making a component. All of it's initialization is going to run, and then after all of that, you're setting the data you likely needed for that initialization.

Chances are you need to make an initialization function yourself and call that after adding the component, and pass the name or enum through that, set it, and then do the init for the component.

[vocal kestrel]

@maiden wadi YOu know what? You're 100% right, i did add thrid person as C++ . However i then added it back as a BP install thinking it'd override it, but clearly it actually doesn't.

So okay, that's a problem solved right there, i'll look into it. Much appreciated!

[maiden wadi]

😄 Happens

[glass stump]

I have a BP of a room that the player enters to progress to the next level. Do I have to create a separate BP for each level, or is there a way to get it to be like 'get current level -> if level = [this] -> open [that] level'.

[gritty elm]

set actor location is not working in oculus vr

set actor location works fine when i don't move(physically). but when i move forward in my room and then again set actor location, it works but it add offset to my walked distance.

also my pawn location still same when i walk in my room in oculus vr

looks like camera hmd position is not relative to unreal character position?

[trim matrix]

I accidently closed my EventGraph in a Blueprint. How to open it again?

There is no such thing as EventGraph under the Window tab

[random vapor]

are you parented to the item? if so its treating it as a relative location

[gritty elm]

i am just setting player pawn actor location to any target location.

it works fine when i don't move in vr mode ( move means physical movement )

i understand my physical movement in roomscale is not relative to player character movement

[random vapor]

hmmm, in my beat sabre-like prototype I haven't seen this, but its in pre-release V5.. I'll check it again

[gritty elm]

it add offset to target location

because i moved in physical space

[brazen leaf]

Did you find it? You should see it under Graphs on the left

[trim matrix]

@brazen leaf thanks 🙂

[modest monolith]

I solved the problem lol

[patent crow]

I'm firing 100 linetraces in a 120 degree cone. How can I force them to fire in the outermost 30 degrees of this cone, excluding the central 90 degrees? I just want to redistribute them to fire more horizontally than vertically.

[glass stump]

Tag me if anyone knows a solution, thank you. :)

[faint pasture]

Random or in a patterm?

[patent crow]

I'm using a random unit vector in elliptical cone in degrees node, with the cone direction being the spawnpoints forward vector and the max yaw/pitch being a float (120 in this case)

[faint pasture]

What i mean is do you want a random distribution or a constant pattern?

[patent crow]

I'm fine with random, this is for an explosive throwable

[faint pasture]

I would just have 1 line trace per 3 degrees in yaw, with a random pitch from -45 to 45

so you'll get a nice distribution horizontally, but each piece of the pie would trace off in a different angle

[maiden wadi]

Sounds like a basic level name thing most likely. Unless you save state for what level you're on somewhere. the BP doesn't really need to do much other than be an overlap with a delegate or game end function call.

[faint pasture]

For (i = 0, i < 120, i++)
{
TraceDirection = (random(-45,45), 0, i * 3)
}

[patent crow]

thanks! i'm gonna play around with this quick and check out the results.

[faint pasture]

Should work alright. I think it might be too random, I'd probably just do a static pattern. Wouldn't really be noticable.

[patent crow]

I'm thinking that might be better for performance. could probably get more predictable results with less linetraces.

I'm just looking to move my explosives away from radial damage. feels gross.

[ivory bison]

Hey guys.. this may sound like a noob question but I had to ask.. can one gamemode have multiple player controllers??

[maiden wadi]

If you mean classes, then technically yes. But not from Blueprint. Though why you would do that is another question entirely.

[faint pasture]

I would do

For (i = 0, i < 120, i++)
{
TraceDirection = (-30 + 30 * i%3, 0, i * 3)
TraceDirection = CombineRotators(TraceDirection, MakeRotator(Rand(-10,10), Rand(-10,10), Rand(-10,10))
TraceVector = TraceDirection.Forward
}

[ivory bison]

I have one C++ class n one blueprint player controller can I use both??

[faint pasture]

You presumably want some sort of random deviation for projectiles, use that same system. An explosive is just a bunch of projectiles all spawned at once. Don't forget the overpressure effect though, there's a deadly radius where it doesn't depend on shrapnel.

[maiden wadi]

Not sure why you need both though? Why not just make the BP inherit from the C++ one and only use the BP one?

[patent crow]

I'll keep that in mind. probably best to either apply radial damage within a small radius, or fire a preliminary set of linetraces with a shorter life and a higher damage.

[ivory bison]

Okay that seems doable.. i can try that. I came to that point bcz I'm still learning.. n i made a BP player controller n while learning GAS i ended up with C++ player controller.. so now I want to mix both

[faint pasture]

Might be unnecessary, depending on your lethality. I can't think of a way to be close to the thing and not eat like 20 traces.

You doing projectiles? I have a very high performance projectile system I'm working on.

[earnest tangle]

Radial damage works pretty well for explosives. Kinda depends on specifics though

[patent crow]

I'm using the smart linetrace projectile system currently, yeah

bullet penetration and solid impact fx and replication were important to me

[faint pasture]

It's really simple. A projectile is just a struct inside a Subsystem. "Spawning" a projectile is just a function call into that subsystem. Projectile flight is just a line trace from Location to NextLocation like most line trace projectile systems. Pretty similar to what you're doing probably, just without actors.

Just a bigass array of AllProjectilesInTheWorld that gets updated at once.

[patent crow]

That's pretty neat, actually. good for keeping track of them all

[faint pasture]

The hard part is visualization, I haven't sorted out how I wanna do that yet. Maybe some sort of global Niagara system is the ticket I'd guess.

I've watched too many videos on ECS, it's infecting my Unreal style.

[patent crow]

I like the idea of the persistent "pool" setup

[faint pasture]

Works crazy well though. 2-3k in flight at the same time is no problem as the traces are so short and it's all in one tight loop.

A pool of 1k should be plenty for even using it for shrapnel.

[maiden wadi]

Does your BP Controller inherit from Player Controller? If yes, just open the BP. Go to the top left an click File->Reparent Blueprint. From there you can parent the BP one to the C++ one.

[ivory bison]

Yes it's player controller.. n thanks man i dint know we can reparent.. that solves my prob without any effort :)

[brazen leaf]

What do I have to do before/after an Add Component node to get it to appear on the parent?
In a simple test throwing Add Static Mesh Component to the constructor of an actor and also trying it on Begin Play, the component is nowhere to be found

[errant cliff]

hey its me again;, i need a bit of help please:

I have this function in my AIC blueprint. How do I call it from my behavior tree?

[errant cliff]

im trying to get the AI to face the player

I was thinking of doing task and call this in my tree, but unsure how to reference my AI there lol

This blueprint (self) is not a AI_MerchantCharacter_C, therefore ' Target ' must have a connection.

[faint pasture]

Be specific. You're trying to reference your PAWN

[errant cliff]

then I was thinking maybe to hack it with a reference within the task but cant do that

[faint pasture]

Get the pawn the AI is driving, cast it to your merchant class, then you can do merchant things with it.

[errant cliff]

ohhhhhh

like this ?

Blueprint Runtime Error: "Accessed None trying to read property K2Node_DynamicCast_AsAI_Merchant_Character". Node: Rotate Towards Graph: EventGraph Function: Execute Ubergraph BTT Find Location to Rotate To Blueprint: BTT_FindLocationToRotateTo

[gilded hazel]

guys, if i switch to another cine camera actor in the level using the set view target with blend node, how do i then go back to the original camera? (its just the default 2d character blueprint)

[errant cliff]

fixed by doing direct connection from receiver event

[errant cliff]

thanks!!!

[glass stump]

Ah thank you i'll try it out. :)

[gentle urchin]

Save it as a variable

You need a set of functions to give it a new mesh if desired. Regular component config is done in the details panel of the add static mesh component node (any add x component node really)

[brazen leaf]

Thanks I was doing that as a test for a custom actor component I made. Turns out you cant see these in the hierarchy and that was really throwing me off. Do you know if there's any way to make it show up in the component list?

[dense thicket]

When i have paused the game by pressing ESC, i cant remove the pause menu again by pressing ESC again, how can this be done ?

[gentle urchin]

Set the input to execute while paused

[dense thicket]

how is this done ?

[gentle urchin]

I think you can just select the input node, and do it in the details panel

[dense thicket]

lol... didnt see that option haha.. thanks man

[astral cedar]

is there a way to do multi threading in BP

like call a function or something on a separate thread

[coarse lava]

Is there a way to set these bounds inside blueprints? I know I can get them from any mesh but there's no node for setting them. Creating a new parameter for setting them only sets them as they already are.

[trim matrix]

Hey does someone know how to block the movement input while im in the settings widget?

[coarse lava]

You can use "Set Input Mode UI Only" and "Set Input Mode Game Only" nodes. What you are having now is like having "Set Input Mode Game and UI" which is also a node that exists. You could also do it the hard way by asking if the character is in main menu (bool) and then hooking that up with the controls that bother you. Make a branch and ask if the character is in main menu and if that is true the controls would stop it right there.

[trim matrix]

ahh i needed a little bit of start. thanks

[trim matrix]

i have one question. Do u know why the isvalid thing doesnt do anything if i want to check if a widget is there or not?

[gentle urchin]

Theres also a disable movement input

[silk cosmos]

By there you mean in viewport? Is valid just checks if the widget variable is set to something. Try is in viewport

[gentle urchin]

Or something alike

In the cmc

[trim matrix]

something like this

i expected it will return if the widget is created or not

[gentle urchin]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Pawn/Components/CharacterMovement/DisableMovement/

This^

[silk cosmos]

When you create your widget set a reference to it and plug that into input object. That will tell you if the widget is valid.

[trim matrix]

i dont have any movement in the lobby i only want to turn the character

[trim matrix]

aaaah okay

[gentle urchin]

Guess i was confused by the phrasing then^^

[trim matrix]

now im confused too

I know that my English is expandable its not that good when it comes to makeing understandable sentences

[silk cosmos]

The problem with doing set input ui mode only is that key inputs are taken up by the ui. So if you want to use keybinds such as esc to exit a menu, you can't. So disabling input to the controlled pawn using the player controller allows for that functionality. That includes mouse input

[gentle urchin]

This is what led me off ^^ anyways, seem you got a valid solution 👌

[trim matrix]

i noticed it now bc i had escape to exit the window i will do that too then

[trim matrix]

ahh i ment the movement with the mouse never mind

[coarse lava]

so...

Is there a way to set these bounds inside blueprints? I know I can get them from any mesh but there's no node for setting them. Creating a new parameter for setting them only sets them as they already are.

[trim matrix]

thats now my settings button

[trim matrix]

thats my escape button and key

[maiden wadi]

Also on top of this. There is a problem with setting input mode to UIOnly. If you are holding movement inputs and call SetInputUIOnly, it will stop all input, but cause the axis to keep moving. You can fix this in a couple of ways, but the easiest requires C++ access to flush input keys.

[silk cosmos]

Quick thing here. Use set input mode ui and game. You also need to give it your settings widget to focus onto. Then on esc pressed set to game.

[trim matrix]

hmm i never did something with c++ xd

hmm i can disable the input but not enable it?

[maiden wadi]

You have to set focus to your widget and use OnKeyDown. Player Controller has zero controlls in UIOnly mode.

I could give you an example, but it's largely in C++. 😄 Unreal is an absolute pain to do real UI and control work in without C++. Blueprints mostly just get you designer level stuff like changing textures or colors.

[solid zenith]

What can I use instead of jump node for character jumping? Ive got this double jump and want to make second jump higher but as far as I see u can only set max jump height in blueprint details and addforce/velocity asks to simulate physics and then my whole movement is broken 😦

[silk cosmos]

Launch character

[solid zenith]

[trim matrix]

np

[fair oak]

how can i check if a collision box is overlapping with any geometric except for the third person player

because i test for overlaping but it only prints the test string for the player

[maiden wadi]

Player Controller class has a function named DeprojectScreenToWorld. It gives you a start and direction that you can use to create a trace with.

[trim matrix]

same for 2 static mesh component.. how to check if they are overlaping?

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Physics/Collision/Overview/

[maiden wadi]

Just invert the check you already have.

[fair oak]

but how lol

i dont want to check for air

[faint pasture]

Have the collision box overlap the other stuff and ignore pawn channel

[fair oak]

where do i iggnore the pawn channel again?

[faint pasture]

The bit that looks like that

There might be a preset that works for you

Ignore only pawn maybe

[glacial eagle]

Am I being stupid, or is there a way to change the precision of a float variable in Blueprint?

I've got a bunch of widget bindings that for some reason have defaulted to double-precision return values

(yes I know, bindings evil etc.)

[fair oak]

yeah but somehow it only prints the string with pawn how do i get the other obejects recognized?

i have a grid around the player will be a furniture system like in animal crossing it should test if a object is in a specific grid field

[faint pasture]

Show your collision settings for the pawn and the overlapper

[fair oak]

no now its shows no string because pawn is blocked

i use a box colider wich should test if there is wall or a actor in the way

[blissful grail]

The only time that I've seen it be changeable is when you pull the pin off and connect to one of the mathy nodes (like the multiply/add, etc..). Otherwise, I haven't seen a way as of yet.

[glacial eagle]

Urgh.

All my widget Blueprints that have bindings have changed the return values to "double precision float"

[fair oak]

so you mean box collider and third person character?

[glacial eagle]

I can't fix it unless I drag another float value over the function and rename it to "Return Value". Bit silly

[blissful grail]

For reference, this is what I mean. It doesn't seem to let you do it if what you're dragging off is a float though. So...yay?

[glacial eagle]

Yeah that's exactly what I wanted/expected

[hexed cloak]

Looking for feedback on a better way to do this. It works great, but has to be manually expanded. Would preferably like it to be expandable based solely on the Section integer?

[spark steppe]

select node

[glacial eagle]

An array of structs with their own array members surely

Accessed by index

[hexed cloak]

I'll have to play around with that.

[winged latch]

Can anyone tell me why UE4 does not let me promote this Game User Settings Object Reference to a variable (or local variable)?
I would like to manually save it within a SaveGame object to be able to save and load different settings for different saving slots.

[spark steppe]

probably not a blueprint type or something

anyways, you won't have luck storing objects in save games either

[winged latch]

So, would I have to save each of the options one by one in a the SaveGame? or is it any other cleaner way to do it?

[spark steppe]

c++ :>

and yea, with BP only its a mess

[winged latch]

But no other way in Blueprint right? 😦

[spark steppe]

i'm not aware of any

maybe 3rd party plugins can do it, like savior

[winged latch]

Unlucky me, thanks anyway!

[spark steppe]

depending on your game you may want to look at those plugins anyways

considering that we have nanite and lumen now, but still can only store basic data types in save games with BP...

[cyan bone]

Im using material World Position Offset, with time and sine to make my texture jump up and down. To make my soldiers look like they are walking. So they hop up a little.
But the thing is they all are doing it at the same time. Is there a way to make this happen randomly, like unsynchronized? So that they dont look like unnatural clones all walking exactly in the same way at the same time?

[faint pasture]

Per instance random

also #graphics

[median monolith]

You just need to add a random initial phase added to the time

Could I suggest you to try to apply ABS to the output of the sine? It would look more like hopping if that's what you want...

[cyan bone]

@median monolith yes looks amazing. Thank you @faint pasture

[cyan bone]

is there a way to control/stop this in the blueprint? Or do i have to create 2 different instances one for hopping and one that doesnt hop?

[paper yacht]

This destroy node giving error how to fix this error...

[maiden wadi]

Don't mix execution lines. Save the variable in one and use it in the other. If it's still invalid, you are trying to destroy a null object.

[paper yacht]

which node should i use to check null or not...

[maiden wadi]

IsValid

[faint pasture]

Dynamic material instances. What's the use case? Why are you animating in hte material instead of moving the mesh or widget?

[cyan bone]

I was told that it was cheaper to animate it using World Position Offset. Rather than vinterp/rinterp to. Isnt it?

I could create 2 instances. 1 when the unit is stopped and another when it is moving/hopping

[cyan bone]

Why dynamic? Why not 2 instances? Create Dynamic Material?

[faint pasture]

Depends. If it's dynamic you'd have a float representing how fast it's moving or whatever.

[paper yacht]

thanks

[cyan bone]

So with the scalar parameter i could have a float that is how fast it moves. And a bool that makes it stop?

[faint pasture]

Just the float IMO

[paper yacht]

Thanks! @maiden wadi it's working and no errors now...
Other query when clicking on multiple time on button it's spawning multiple actor. but i want only one...

[cyan bone]

[paper yacht]

Worked Everything Fine Now Thanks! @faint pasture

[rich jungle]

I have an array of structs.

If I get the struct directly, and then modify something inside them, that works like you'd expect.

However if I get the struct through a function and return the struct, I'm getting a copy of the struct instead.

Am I missing something? That seems kinda nutty

I'm certain the function is passing back a struct reference, not a copyu

[desert juniper]

I ran into this before when the struct was a CPP struct, and I was trying to modify it in blueprints

[rich jungle]

this is a blueprint struct at least

[desert juniper]

or when the actor was a cpp actor

[rich jungle]

100% blueprint project

cause lazy

that's the only scenario you ran into it?

any workaround?

[desert juniper]

for me, yes
I know you can take the copies values, split it, and reassign the struct to be equal to a new struct that contains all those values

it's messy, but works. Basically, rewriting the value of a struct, with a new one that's mostly a copy of the old one with a few tweaks.

[rich jungle]

gross

thanks, it works

but I'm not happy I have to use it lol

either way, <3 @desert juniper

[desert juniper]

if you find a better solution, ping me 😄
I've moved away from that workflow due to that

@rich jungle Found the convo
#cpp message

[maiden wadi]

Am confused. What is it you're trying to do? You can pass structs by reference into a function.

You can't return it of course. But if you're returning it, you'd already still have access to the struct where you'd be calling the pass by ref function anyhow, so not really an issue.

[rich jungle]

I need to modify that structure after finding it through my function

so having the function poop out a copy is a problem

[maiden wadi]

Make a find index function. Get as a ref

[rich jungle]

yup

doesn't work

that's what I'm talking about

you get a copy

[maiden wadi]

Yes it does.

[rich jungle]

even if you "return ref"

I triple checked it

this doesn't work

[maiden wadi]

You don't return the ref. You can't return a reference. You return the index and use the index to get the ref.

[rich jungle]

this does

yeah, the "you can't return a reference to a struct" was the crux of the issue

[maiden wadi]

I'm not sure I understand the issue. It's just as easy to create a function that gets the index to manipulate.

[left carbon]

Does anybody know, what this error might mean? Game crashes right after launch.

Error: Missing import of (/Game/UI/Lobby/TrophyRoad/W_TrophyRoad_Progress): MetaRewardBuilderRawInfo_0 in Package /Game/Blueprints/Meta/BP_MetaController_Progression was not found, but the package exists.

It also happens with some other blueprints

[rich jungle]

I don't have access to the array itself because I'm doing RPCs

[maiden wadi]

How are you finding the copy you're returning?

[solid zenith]

How can I enter gate node periodically while button is held down?

[rich jungle]

create a timer, clear it when button released?

[rich jungle]

2d array coords

[maiden wadi]

But aren't you doing something in the two functions that retrieves a copy of a struct, and then using that manipulated copy to overwrite the other?

[solid zenith]

nice works thx

[spark steppe]

wasn't it impossible to get struct refs from arrays?

you may return a ref to a copy of the struct?

[maiden wadi]

You can get a ref from an array of structs just fine.

[spark steppe]

nvm, you are correct (now i wonder what it was that you couldn't get as ref from an array....)

may have been objects, as they are references
