blueprint

[lime crow]

like this? this caused no errors

[distant hollow]

Yep cos when GameInstance_Cast is not ready it would just flow past the IsNotValid node

And it will flow through the IsValid node and retrieve the data once it is ready

So your issue has been fixed?

[scarlet ledge]

Anyone use Epics Citvy Vehicle example cars, why do they look like crud?

[lime crow]

ooo i see now, interesting, so that is similar to a isvalid node?

[distant hollow]

How and where did you call the SaveGame function?

[distant hollow]

Yep

If you get errors such as "is pending kill" then this Validated Get would work well against it as well

[lime crow]

@distant hollow @spark steppe Guys just want to say a huge thank you - you have been a massive help and apprecite you taking your time to help. I learnt alot during this as well. Thanks

[jade prairie]

The save and load function is called via keys

[distant hollow]

Show the part of the code where the function is called

You are either missing an input, or when you call the SaveGame function, the Actor which you are putting through is already invalid

Likely you have Destroyed the Actor before passing it through the SaveGame.

[distant hollow]

Missing input

The error is likely happening when you pressed V

[jade prairie]

I inserted default actor from cast there and it doesn’t work

[jade prairie]

yes

[spark steppe]

did you mean to call your custom event's?

[distant hollow]

Show us how you did that?

[distant hollow]

So it means that there were no Actors to read from in the SaveGame function

Because there was no input

[lime crow]

sorry quick question, how did this work? i created a variable from a cast, but disconnect the cast and used a get is valid node, im assuming its still stored in a game instance variable even though there is no direct cast?

[jade prairie]

I understand that the actor has been destroyed

[spark steppe]

that's not where you should replace it

you keep the cast on begin play, but you remove the cast (and replace it with the validated get node) in the function which updates the text

[lime crow]

i see - this was on the begin play of the second level, just curious because it still all works

[spark steppe]

no it doesn't

it works, because your updating text function probably still gets the game instance from the engine and casts it every tick

but chances are that your beginplay stops right at the validated get, and all the stuff later wont ever execute

[river schooner]

W ben

[lime crow]

o i see, i wont touch that then

[spark steppe]

no, the real hero here is @urban coral for all the help provided :>

[river schooner]

what did bro do

[jade prairie]

How to pass the actor there so that it can read and save?

[spark steppe]

you only want to save the actor which fires the event?

[distant hollow]

This would probably slip through the Not Valid node because you haven’t defined it, it would be null

[tiny wing]

try to call "save" and "load" instead on save game and load game on inputs. it may fix

[distant hollow]

The cast node takes the GameInstance, and the Set node sets the “GameInstance_cast” variable to the GameInstance
This variable is not stored inside GameInstance, it’s on the blueprint where you cast it.

[distant hollow]

Depends on context, what are you trying to save? Does every time you save have to involve the Actor?
If it doesn’t, then you could use a IsValid on the Actor before proceeding with Actor related sequences.

[jade prairie]

I need to save the actors changes and load them

[spark steppe]

all actors?

[distant hollow]

Then you need to pass the Actors through when you use V key

Which Actors are you trying to save? Get a reference to that Actor and plug it as the input when you call SaveGame on V key.

[river schooner]

didnt you say that it was not possible to save actors?

[lunar sleet]

You can save their variables

Not the instance

[river schooner]

okk

[urban coral]

stfu Ben

[river schooner]

what happened

[untold rain]

dont if the logic isnt correct, but it prints 3 times

[lunar sleet]

Not sure what you’re asking

You should be printing the actual actor not Hello

Much more effective debugging

[spark steppe]

from the little information on the screenshot i would guess that he might trace 3 times

[river schooner]

I got the covid.. help<

[lunar sleet]

#lounge

[spark steppe]

please no

[river schooner]

me crying

[lunar sleet]

Yeah, part of why I suggested printing the actor

[river schooner]

how to make a if statement with strings

@lunar sleet

equal<

if they are eqal

[untold rain]

oh ye its being traced 3 times , why is it?

[barren tangle]

Do you know how that node works?? what is the link between that node and the Max Walk Speed?

[spark steppe]

stop pinging random people

[river schooner]

he was talking to me tf?

ben

[spark steppe]

idk, your screenshow only shows potions of what you do with the trace result...

[spark steppe]

no, he was talking to Mytho

[river schooner]

can yo uhelop me then?

[spark steppe]

yes, but no (i'm not that helpful as you know...)

[lunar sleet]

Sometimes we could use an age limit 😀

[river schooner]

? cmon ben you are helpful I lied

you are just better

[untold rain]

it printed the same actor name 3 times

[river schooner]

i am 21.

[spark steppe]

twisted some numbers here, didn't you?

[lunar sleet]

Can we see what fires this trace?

[river schooner]

can you help me please ben.. i am a beginner

not working

[spark steppe]

weird, it works here

[river schooner]

I just did a pure equal so thats working

[spark steppe]

you are still only showing your trace and result handling, not what is causing the traces to happen

[river schooner]

this guy is trolling lmao

[lunar sleet]

No, you are

[barren tangle]

what are you trying to do alex?

[lunar sleet]

String comparison is likely ===

[river schooner]

we need to see what is before that to know if its a loop or somethinmg specific

[river schooner]

yea i know now

[spark steppe]

somehow i want to see where this leads if alex takes the lead here 😄

[untold rain]

its actually connected to a func and am calling it every 0.3 sec using set timer by func name

[spark steppe]

on the other hand, that would be unfair to Mytho...

[lunar sleet]

So umm

[river schooner]

bro I amk not that bad

[untold rain]

is this u r brother or smth

[wild moat]

anyone know the best way to set up (modular) character with changable skeleton size?

https://forums.unrealengine.com/t/best-way-to-set-up-modular-character-with-changable-skeleton-size/407046

[lunar sleet]

Why are you asking us why it’s printing multiple times if you’re using a timer to do this to yourself lol

[river schooner]

LOL

[lunar sleet]

Maybe #animation

[untold rain]

uh i actually added a condition there

[wild moat]

i'll try that thanks

[spark steppe]

https://docs.unrealengine.com/5.3/en-US/working-with-modular-characters-in-unreal-engine/

did you read this?

[untold rain]

i have a var and i m checking if it is not equal to the hit actor then setting the var to hit actor and print

[barren tangle]

No one is able to answer to my simple question?

[river schooner]

IS THERE A FONCTION: get actor by name?%

[wild moat]

yes but that assumes that the skeleton is the same for all modular parts

[river schooner]

show us the entire thing please

[lunar sleet]

Debug and find out if that second var ever changes, my guess is not

[lunar sleet]

Maybe try bumping the actual question ?

[barren tangle]

this one

[spark steppe]

compared to the other stuff here this is rocket science... my guess is that it accelerates the character until it reaches max movement speed?

iirc there's an acceleration rate in the character movement component!?

[lunar sleet]

Yeah

[spark steppe]

no, but there's get Actors with Tag, so you can add tags to actors to find them

[untold rain]

nop not printing

[river schooner]

no

[spark steppe]

xD yes!?

[river schooner]

I am not going to generate tag

[spark steppe]

then you aren't going to find them 😛

[lunar sleet]

If it’s staying as null, your condition always returns true then

[barren tangle]

lol, so it's a difficult question 😄

[river schooner]

can we go in a vc and you could help me out?

[lunar sleet]

Yes, CMC is very complex.

[untold rain]

but then should have printed more than 3 times right

[spark steppe]

no, it just requires experience with character movement, eventually you ask in #ue5-general if you don't get a response here

[lunar sleet]

Depends, not sure when your timer is told to cease, if it is

[river schooner]

1% of gross revenue if we vc and we pack it up, its the biggest problem and the last one

[lunar sleet]

1% of 0 is 0

[river schooner]

1% of 10000 is 100$

doine

[distant hollow]

Gosh the chat is a mess lol

[river schooner]

i am currently doing the thing you said

I am trying to save the actor names

[distant hollow]

Names? You mean the class?

[distant hollow]

What’s your question again?

[river schooner]

their actual name

[untold rain]

0.3 secs dealy and btw ye it prints 3 times the previous one too like the entire code is running 3 times

[distant hollow]

Ok, and what were you trying to do with it?

[barren tangle]

here

[thin panther]

why are you crossposting

[lunar sleet]

Honestly the whole code looks problematic.

[river schooner]

setting the saved name to the new actor

[spring osprey]

it says not to use this as ID

[untold rain]

how

[lunar sleet]

You’re only setting the other variable if your first bool, whatever that is, returns false for starters

[river schooner]

then how should I do it

[lunar sleet]

Also I asked when your timer is told to stop not how often it runs but eh

[spring osprey]

tags probably, that's why they are there

[distant hollow]

It’s quite pointless to save that actually, what is your use case?

[lunar sleet]

So what are you trying to do here?

[river schooner]

so I should generate a random tag for each actor?

[distant hollow]

And what exactly are you having trouble with?

[river schooner]

I need to save a propretie of an actor that I can use to find it

[distant hollow]

A class or a tag would be your best option

Display name is not likely going to remain constant

[untold rain]

ah i quit

[river schooner]

class?

[spring osprey]

so you need a unique ID for each actor?

[river schooner]

many actors can have the same class and thats not what i want

[lunar sleet]

If you want to clear the timer and stop firing the trace once the correct actor was hit, just clear and invalidate the timer, no need for all those checks

[distant hollow]

Yes, like the BP class

[river schooner]

yea

[barren tangle]

If my Max Walk Speed = 1000m/s and i only have an Horizontal movement (X) i will move on the X axis at 1000m/s.
If i add a vertical movement Y. That's mean my movement will try to reach the Max Walk Speed (1000) but on the 2 axis. that's mean my speed on the X axis will slow down.

and it's an issue for me 😢

so there is two possibility

1. something exist and i don't know what
2. nothing exist and i have to go with lot of complexe physic and math calculs for that

[distant hollow]

It’s something like what I’m doing
You can have a string variable in that class
Then Get All Actors of Class, pass the array through and check the variable until you find a match

[river schooner]

but the other guy said that we shouldnt do that

[untold rain]

so like make a var timer and set it to the timer delay and once actor is hit, change timer to 0 and then when no actor is hit set time back to the initial value? smth like that?

[distant hollow]

If I understood it correctly, it will move at the same speed towards both vectors
So if you have two actors on the same speed, one heading south and one heading southwest, their Y values should remain the same.

[lunar sleet]

No no. your timer return value, promote it to a variable. Run the trace as you are now. Cast to the actor you want to hit. On success, grab that handle variable and use clear and invalidate timer. Done

[barren tangle]

yes

[thin panther]

could you continue this one in #ue5-general ?
The two conversations on the same topic being maintained is rather confusing

[distant hollow]

I’ll take it to private

[barren tangle]

but because of the max walk speed i slow down automatically, and that's annoying

[distant hollow]

PM

[distant hollow]

Where?

[spring osprey]

if you are refering to me, I only pointed out that you shouldn't use Display Name as an ID. The suggestion was to create a string variable and give that a unique value which is perfectly acceptable, though looping through them all seems unnecessary. I'd suggest a map for efficiency purposes assuming there are a lot of them and you need to look up frequently

[river schooner]

.

[wide schooner]

Hey, i'm using a spline in an actor and the actor is scaled in the world. The problem is that when i scale the actor (which also scales the spline), the spline length is not updated and doesn't correspond to the real length it takes. Is there to update the spline length based on it's scale ?

[untold rain]

but i want to recheck again after player rehit with that actor

[distant hollow]

He said you shouldn’t use the display name as an ID, not a variable.

[river schooner]

what's an ID? cuz i am also using that in a variable

[lunar sleet]

Like you want to keep tracing ?

[distant hollow]

Map? How would that be done?

[distant hollow]

It just means an identifier, nothing specific
It can be a string or a set of numbers, depending on yourself

[spring osprey]

key is the Unique ID and value is the actor. Could cache each the first time they are found in the loop to prevent continously looping through all objects

[river schooner]

So, should I use a random tag generator for each build actor to be able to get them easily?

[spring osprey]

really depends on how frequently this operation is used and how many objects looking through to make it worthwhile

[river schooner]

1 time

[spring osprey]

oh then no need to use a dictionary

or i mean map

[river schooner]

yea

[untold rain]

yep

[river schooner]

but should i use tag?

[distant hollow]

My use case is that every piece of wall/floor have a random unique ID assigned when they are first created
This unique ID will be saved and maintained when these structures are reloaded elsewhere.

[river schooner]

bro copied me

[distant hollow]

You can use a tag or a string variable like me

[river schooner]

how did you do the breaking child/parent system?

[distant hollow]

Erm diff is I already have it done up earlier on today, I am just exploring to see if there are any methods with better efficiency instead of double looping

[distant hollow]

Wdym?

[river schooner]

can you break the walls/floor

[distant hollow]

So not applicable…ok tks

[distant hollow]

What do you mean by “break”?

[river schooner]

can they break somehow

like most games

[distant hollow]

Like I said, what exactly do you mean by “break”???
Destroy?

[river schooner]

yea

[spring osprey]

i think he's talking about a destructible environment mechanism

[distant hollow]

Any actors can be destroyed. I don’t understand your question.

[river schooner]

ofc

[distant hollow]

Paint a scenario?

[river schooner]

then how did you do that system because when you destroy a wall, you might want some other actors relied to it to destroy too

[spring osprey]

its not clear in here, in blueprints break means something different

[distant hollow]

Like a window or door on it?

[spring osprey]

well if you have an object that depends on another object, You could fire an event before you destroy it and then have all dependent objects listen to the event

[distant hollow]

You want to destroy those attached actors when the parent actor is destroyed, is that what you mean?

[river schooner]

how do you know if they are dependant?

[spring osprey]

idk it depends on the specific situation

[distant hollow]

You can use a Get Child Actor / Get Attached Actors depending on how you constructed them

[spring osprey]

like if you had a rafter with support beams and you wanted the rafter to be destroyed with the support beams the rafter would need to reference the beams somehow

[distant hollow]

That’s up to your design.

[untold fossil]

Is it normal behaviour that I can see debuglines on the client, even when they are only created on the server?

[spark steppe]

the spline component has an Update Spline method, did you try to call that one? (just a wild guess, not sure if it helps you with this issue)

[spring osprey]

the child actor seems like a good option, without knowing more about the requirements

[wide schooner]

I'll try that thanks !

[river schooner]

so basicaly there's my problem, I build and everythings good and the parent/child system is fine but when I leave and rejoin. Everything resets and then it doesnt work so that is why I need some kind of propreties or an ID to get access to them and set them proprely when rejoining

I will try with a custom build ID, ty

[wide schooner]

It worked, thanks a lot, i was struggling to find something

[distant hollow]

In my case when I created Windows and Doors on my Wall they are stored in an array
When I respawn them using a function on the wall itself with the array information I attach them to the Wall which owns the windows and doors

So it really depends on your design and how you want to work with it

[river schooner]

k

[distant hollow]

What I have now is a BaseStructure class which is the parent of my Wall and Floor blueprints
In the BaseStructure class itself I have a “UniqueID” string variable and a “StrctureType” enum variable, so both Wall and Floor blueprints can also have the same variables

So when I load the structure I can read and match the UniqueID in my savegame.

[lunar sleet]

Then don’t cancel the timer 🤷‍♂️ . It’s difficult to give you the right answer when we don’t know what you’re trying to achieve with all this tbh 😀

[abstract oar]

Need help with Add Movement Input inside ai character, the character doesn´t move

[hushed berry]

Hello, everyone. It's my first question here so. Nice to meet you all. I have a pickle problem that I cannot wrap my head around. I've tried everything that I know, and somehow the thing that at least for me is supposed to work doesn't work as expected. To summarize: I have a retriggerable delay that spawns a cube right under the character. I gave the delay a condition IsAbilityActive that is supposed to turn it on or off. The events "activateability/ deactivate ability" trigger only once with each press of a button. Here is the problem. Even though that the "deactivateability" event sets the bool to false, the bool gets activated right after to true and the ability keeps going. I'm not sure as to why that happens as this is the only place where the variable can be set and after deactivating the ability the "activateability" event doesn't trigger, hence I don't get why the variable still gets set to true.

[river schooner]

why does it look so bad? I cant even look

[distant hollow]

Put your values on a tick and check them

[abstract oar]

Tried it, same value

[distant hollow]

How did you call your Activate? Show the codes

[hushed berry]

It's a long noodle but after I put the string on event tick there seems to be some shamblo jumblo happening. So even though the response wasn't to me it helped 😄 thx

[distant hollow]

As long as it works

[undone sequoia]

guys how i can make prediction for bullet at target? I mean I wanna draw circle before target so I know I need fire in that circle when target is moving

😄

is there any function?

Maybe getting the wrong vectors/values? Play around with the links

[distant hollow]

Line Trace

From the muzzle to the hit location

[abstract oar]

It won´t jump either

[undone sequoia]

line trace is straight

i have realistic game

i want add prediction

like here

warthuder have same

[distant hollow]

You mean like a trajectory?

[undone sequoia]

yea so when u shoot in white circle u hit because plane has some speed + bullets have some speed you cant shoot directly on target

[distant hollow]

https://youtu.be/TAnzmz2AviY?si=LUladvoN9eRtzS9S

Try this

[undone sequoia]

like this i have for bombs but cant use same for plane target i mean 😄

thx

[random pulsar]

hey can i make a web build on unreal?

[rough wing]

Why is there a delay between when I invalidate the timer and I can start it back up again?

[thin panther]

Not anymore

[random pulsar]

hell no

[abstract oar]

Huh, it worked, I forgot to set auto possesed by AI to spawned or placed in world 🤣

[elder lodge]

the bullets need to inherit the velocity of the player

[elder lodge]

gonna have to do some algebra and geometry
roughly something like:
target_current_position + time * target_velocity = target_position_at_hit = player_position + time * bullet_velocity
bullet_velocity = bullet_direction * bullet_speed
Then solve for bullet_direction and figure out how that displays on the HUD.
Not sure if time cancels out there? Might need curent_distance_to_target to complete a triangle and do some geomtry for it.
Maybe try #game-math
I think another equation relating the sides and angles you know might get rid of the last variables, like Law of Cosines

This article has some really complicated stuff involving gravity, but it depends on if you're simulating that for projectiles.

[wild moat]

alright they didn't have an answer in #animation so:
anyone know the best method of attaching different skeletons together?
like Bionicles, not modular characters but modular skeletons

[supple dome]

what about just doing that?
Its pretty common to have skeletal meshes attached to other skeletal meshes

ie. attaching wings to a character, would work just fine

[wild moat]

is it really just that simple, i'll give it a go

[supple dome]

the hardest part would be if you want smooth mesh transitions between different skeletal meshes, but if you are fine being different objects, should be easy

[wild moat]

morphing between them would be cool but not really necessary, i'm fine with pop in and out, nothing some vfx couldn't hide

[austere coyote]

I need some help, does anyone know how to call a event created in a level blueprint from an object?

context: i have a pause menu and i want the game to re add all the previously hidden widgets when the resume button is pressed. The pause menu widget does not have a reference to those widgets but the level BP does, so i want the event of the Level to trigger upon this specific interaction of the pause menu.

[random pulsar]

The game is working fine in editor ,also as standalone but when i built ,animals are strange

[copper tree]

Anyone know offhand if multimaps are supported in blueprints?

[digital valve]

Hey guys im having a issue with my equip/dequip remove stats. Im not sure what to make of this. Equiping works and updates the stats but removing it will not. If anyone has ideas how to fix this or do it better Id love some help

[frosty heron]

No, unreal engine only support single world out of the box.

You can buy multi world plugin if you want multi world but it will cost hundreds of dollars

[copper tree]

Referring to the container type: https://docs.unrealengine.com/5.0/en-US/map-containers-in-unreal-engine/

[frosty heron]

Well then not sure but I will wager the answer is also no

[copper tree]

That's kind of what I assumed but was hoping not 😦 Thanks

[remote meteor]

what is multimap anyway

the value of the map is another map?

you can just encapsulate the second map in a struct if its so

[spark steppe]

yea you could actually model the wings so that they are kinda on "ground" by default and then define virtual bones for attachments in your character skeletons

then you would attach the addition to those virtual bones/sockets

[remote meteor]

oh you mean std::multimap? probably can implement your own

[copper tree]

It's a map that can have multiple keys with the same value. A standard map would only allow unique keys. I didn't think ahead with my inventory system and used maps, but to allow stacking, multimaps would be the answer

[remote meteor]

map value to a struct, with an array within the struct, probably can achieve the same

[copper tree]

That's what Chatgpt recommended lol, I may give that a shot

[proper flower]

guys yoday I tried after some suggestion but unfortunately I was not able to solve this cast.

what's useful and what's to delete

I tried many combinations and logic but none seems to retrieve lifespan of my entity

now the component are disconnected, I know, but can I sort things out by these components? or I need others too?

the actor variable : tried as actor class, actor object reference, entity reference itself.

none

used get actor of class as it is, connected with print and get life span, but none

used cast to, with object of different types, but none

why this does not work?

accessed none, so it cannot find the target

[faint pasture]

Multiple values for a key

I use it to store an adjacency list

[crystal crown]

Does it matter if i use float or int for health?

[faint pasture]

Depends on your system

[crystal crown]

wym? atm there is no complex system

[copper tree]

Use Int if you want whole numbers for health values, float if you want decimal points

[crystal crown]

okay ty

nobody cares about decimal anyway

[violet wagon]

do you have an "Asteroid field" in your world when you're calling this? GetActorOfClass gets whatever is in the world currently

[proper flower]

I solved in a completely different way

thanks anyway

yeah was generated in runtime

[trim matrix]

bit of a silly question this one but if I want to launch the enemy character at a particular location so that what I end up with is enemy launches toward player mesh

I currently have it kind of working but the enemy always ends up slight to the right of the player rather then at the,

*them fully

thats my code so far. and in my behavior tree I have it rotate to face the target before calling launch in the enemy BP

[faint pasture]

face the target probably has an accuracy threshold

instead of forward vector, launch them actually at the target

[trim matrix]

it does haha

precision

[swift kiln]

Hey I made a thing where actor will spawn at random location inside a box collision and I wanted to know how can I implement, that around for example my character there would be a radius where that actor just won't spawn

[faint pasture]

You're doing:
Look at target
Launch forward

any inaccuracy in look at target will be amplified by the launching.
Instead, do this:
Look at target
Launch at target

[trim matrix]

well I tried that but couldn't see what I was confusing as I would prefer to launch at the target then well just forward direction

[faint pasture]

Your launch direction will be Normalize(TargetLocation - CurrentLocation) instead of Forward

Or if you're trying to land on them you can use SuggestProjectileVelocity

[shell wren]

Really quick, I have two BP's that went missing in editor but exist in my folder explorer, how can I pop these two back up in the editor? Importing isn't a option - uasset

[trim matrix]

yep works like a charm

using the suggest projectile thing

[ruby cobalt]

My cine cam focus is set on this green translucent plane here, which can be parented to anything.
I'm trying to orient it properly so it faces the cam.. but i fail to understand how to process the rotator here.

[undone sequoia]

thanks I will check I think I already solved it I need test it but I did same approach like u said

[digital valve]

anyone able to take a look at this. Its driving me nuts 😭

[trim matrix]

So got this issue I'm not sure on

I have a collider that overlaps with player and it's doing stuffright

[spark steppe]

you win the price for the most cursed video example i've seen here so far, shouldn't it be fine to just copy the camera world rotation to the plane?

[trim matrix]

however when it launches the bot doesn't seem to be setting at the location of the socket name given and yes I defo have a socket on mesh with that name

any ideas here ?

sometimes it'll kind of attach and slowly sink it's really confusing

[ruby cobalt]

oh you have no idea.. i'm going for some backroom creepy shit where I'm breaking those fingers and all

[trim matrix]

I even checked with a sphere to ensure its right and it is

[spark steppe]

also i think you should ignore the roll which "find look at rotation" might return

i think the roll will always be wrong

[ruby cobalt]

damn actually yeah.. it's just the camera's absolute rotation

and possibly an offset based on the plane default orientation

[spark steppe]

stop it

[ruby cobalt]

dat UE5 bloom and short DOF tho

[trim matrix]

anyone help with my issue at all ?

[ruby cobalt]

i don't understand your issue

[faint pasture]

Why do you have so many RPCs and no replicated state?

[trim matrix]

sorry so basically

I have an enemy thats launches at the player and if their collider overlaps with player they stick to player as it where

I'm using attach actor to component for this so the actor being the enemy and the component being what it's hit

my attach rules I've tried them all.

at the moment the issue is it doesn't seem to attach and either ends up off somewhere or ends up sinking into the ground. I have disabled collision on enemy and also set it to flying but I can't see to get it to work

I was having issues like this before to be fair the attach actor to component thing but on something else

[ruby cobalt]

do you think they don't attach because they are tied to something else and have to be released first?

[trim matrix]

there not attached to anything else

[ruby cobalt]

how do you launch them?

[fading otter]

my grenades (projectile movement component) are not smoothly updating over the network despite very generous interpolation settings -- anyone know what might be going on here?

[trim matrix]

So you can see here how it's attached but inside and not at the socket location I've created on the player mesh

like that

[ruby cobalt]

hmm 1s i'll try to figure it out

i had this issue I believe

hmm so attach on bone will attach at the bone's base.. which is inside the character

you need to offset the attach point

@trim matrix different context but same logic I believe.. it attachs at the center of the target.. but offset it by "its current position" https://youtu.be/FK7FBBdY5fY?si=Qk2X7bEET1_3FO5E&t=166

btw, if you use physics control to attach like they show in this demo, you have have the objects dragged to their parent using physics and then you can have them bounce

[trim matrix]

Hmmm I'll take a look

I'm bit surprised it's this difficult for it to work

I'm giving the attach a socket name as well so surprised it isn't doing stuff right

[ruby cobalt]

what about using hit location?

[trim matrix]

won't be able to

issue with attach actor to component is it don't take a vector in

I would prob have to set the actor location location and rotation at same time of attaching

[ruby cobalt]

i believe attach is the same as parenting in your BP editor..

meaning you need to change relative position to offset

[wary trellis]

Im trying to pull the players character into the center of a TriggerSphere, but to use AddImpulse I need to simulate physics for the capsule component, which messes things up, so instead I can set the position of the actor over time but dont really know how the math would work

[surreal peak]

You can add impulse on the character movement component afaik

Without physics

[faint pasture]

A pull would imply being done over time, use AddForce assuming the CMC implements it which I'm pretty sure it does.

[wary trellis]

this is inside of the level blueprint, ive tried using the character movement component but still gives the error that the capsule component needs physics enabled

[river schooner]

Hi ben

[wary trellis]

ill try this

[river schooner]

why is the ID value always saving as 0 when it should be another number

[faint pasture]

remember, physics units in Unreal are really small so you'll need to apply large forces and VERY large torques

[river schooner]

is this a unreal bug?

[faint pasture]

Show how ID gets set

[faint pasture]

So show where that Own ID comes from

[surreal peak]

Also use PrintStrings and Breakpoints to debug your code

[river schooner]

I know, after the event add build child, it prints a random number between 1 and 100000 but when its time to save, the number is 0 for some reason

[surreal peak]

Maybe check for any setters that set it to 0 and breakpoint those

[river schooner]

nothing...

[surreal peak]

Then you might be printing/saving an actor that you didn't call that interface on

Maybe check if the hit actor and the one you save in are actually the same

Fwiw there is an unreal bug that could cause the variable to stay 0. That one would be fixed by just redoing the variable

But idk how that bug is triggered or if it still exists

[wary trellis]

I have this, which works, however how should I weaken the force the closer the character is to the center of the sphere

[faint pasture]

however you want

[surreal peak]

Calculate the distance between center and character

And divide it by the max distance

[faint pasture]

There's an Add Radial Force node that might have some falloff stuff you can tweak to do the math for you

[surreal peak]

Then you have an alpha value that goes to 0 the closer the character gets

[faint pasture]

Calculate distance, map range clamped that distance to some force strength you want

[river schooner]

yea they werent, tyy

[regal bane]

Is it possible to have an actor blueprint that randomises its static mesh every time it is spawned? I would like it to have a random width & height and use something like the deform tool in the modelling mode and change the seed of the perlin noise randomly. I have failed at googling can someone point me in a direction if it is possible?

[wary trellis]

would something like this work

[faint pasture]

I would use map range

[small wedge]

I'm making a small translator:

TIPA to IPA
X-SAMPA to IPA
IPA direct input (no translation)

I want to have one text field where the user can input text, and select which of the three translators they're using. Are enums the way to go about this, or something else?

[faint pasture]

much simpler and quickly tuned

[wary trellis]

okay so it works but isnt really aggressive enough with weakening the closer to the center, but im not really sure what to change in the map range clamped to tune it

[surreal peak]

The Out Range A, I guess

[viscid flower]

Hello I am struggling with something that seems so simple, yet not working

I want to loop a spotlight color change in an order (either from an array or just directly by using set light color)

First, I have this, but 1) it doesn't seem to execute in order of the sequence for some reason

and not sure how to make it repeat infinitely

[river schooner]

the way sequence work is that it will do instantly the first 1 and then the second 2.... without even finishing it so it will not wait 5 seconds.;.

[viscid flower]

ohhh I see

[thin panther]

yeah, you misunderstand how a delay and sequence works. It does not respect asynchronous actions.
use a looping timer for 5 seconds, each time you run the function, go to the next element in an array

when you go out of bounds, loop back around, or do nothing

[viscid flower]

looping timer?

do you mean timeline?

[bleak kelp]

you can set a custom timer to fire an event with a delay

https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/UseTimers/

[thin panther]

no, i mean a looping timer, as show above

[viscid flower]

this is another attempt I made, but I dont think I am using the for each loop correctly haha

[viscid flower]

reading this

[faint pasture]

For a quick and dirty version, you can just hook those all up in a loop. Change color, delay, change color, delay, change color, delay, go back to change color

[grave relic]

Does anyone know where I could start with taking damage on impact? So I have trees as in Valheim, when you chop them down they fall over. And I want it so if the player is not careful they can get hit and take damage. I don't know how to make this impact damage based on the tree's velocity and if it collides with the player. Any tips? 🙂

[faint pasture]

Event hit impulse magnitude

That's how hard the hit was

[viscid flower]

Got it to work! Thanks all!

[grave relic]

Where can I find that? When into the static mesh and took out "On Component Hit" but cant find anything relating to magnitude 🤔

[winged totem]

Hi Guys, is it posible to do with Unreal a feature like in this video? When you pick a coin the 2d coin is like simulaing physics an then takes the correct place in the bag. How would you do this?
https://youtu.be/errcUtHvDqU?si=mj_bQ97hZ-su7S5K&t=138

[digital valve]

Ive been following a tutorial for the most part. Im pretty sure so its persistant through levels

[faint pasture]

There are no good tutorials, and that goes doubly for multiplayer

[nimble wasp]

I'm setting up a 2D character in a 3D world. How can I simply call a flipbook to fire when the character (not the player) moves right, left and forward?

[stiff swift]

Copilot mentioned using a set Flipbook node possibly

U4 instructions and not sure if good but what it gave

[nimble wasp]

I love this discord. Thank you two!

Now I just need to figure out when my NPC is moving right or left to set the appropriate flipbook. I think this does that.

[faint pasture]

that'll tell you if it's moving but not which direction

[nimble wasp]

How do I tell which direction it is moving towards? I am only using the four primary directions, so I know I need to check x and y - but I don't know how to tell.

Gonna try this. https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/4/d/74dc48bdb3c484443b654c401f4589ee7ad971f9.png;

[digital valve]

indeed I try to go offscripts reguarly such as what im doing now adding attributes to equip dequip. Im just confused on why dequip wont work ;\

[stiff swift]

If the last one worked ill drop this then let me know I suppose, copilot myte be decent for a good helper (free on the playstore) with recent programming info added for us to play with

[full turret]

Hello. Is there a way to execute/play the timeline in editor? Trying to get a ping pong like movement but I need it in editor, not during run time. Event Editor Tick makes the other functions run in editor but it's not working with the Timeline node.

[frosty heron]

Why don't u connect the update exec?

[full turret]

My bad! Old screenshot. Update exec connected, still not working

[frosty heron]

Not sure about editor time. 🤔 , you prob can't? The time doesn't seems to move

[full turret]

Is there another way to get a ping pong like movement without the timeline?

[frosty heron]

Wat r u trying to do?

Why does it have to be editor time too. Normally it's kinda useless to do something visual like that in editor time?

You can probably use material that utilise wpo.
It's a common technique to rotate massive ammount of actors like coins in runner games

[full turret]

Trying to move an object in a circular/eliptical path (ideally with variables for radius/axis) in a loop for a light to track. I'm doing linear content but don't want to keyframe trackers in sequencer

[frosty heron]

No idea, gl

[zealous moth]

merry christmas

[frosty heron]

Merry Christmas to you too 🤗

New year soon

[zealous moth]

indeed

no idea what resolutions to make...

[faint pasture]

Tick -> update position

if it's meant to be continuous

a timeline is just a temporary ticking thing with animation tracks

[full turret]

I was trying to use the timeline to loop between the values -1 and 1 (to get the ping pong effect) and then multiply the value by a constant and offset the position. Is there a way to continuously loop between -1 and 1 without a timeline?

[faint pasture]

I mean why not just use a looping timeline? You're reinventing the wheel here

[distant hollow]

But why do you need that in Editor mode?

[full turret]

Can I get the animation from the timeline in the blueprint to sequencer? I need to render the animation

[full turret]

I was using the looping timeline but can't get it to play the animation in sequencer

[faint pasture]

This being sequencer certainly throws a monkey wrench in it

[full turret]

Pretty much. I can keyframe the movement I need in sequencer but there are quite a few trackers that need to move around for the lights to follow and I thought I could make some parametric animations in blueprints with a couple variables for the radius/axis of the circular/elliptical path for quick animation iteration

[minor pollen]

Question, what is the difference between equal to (==) and equal to exactly (===)?

[wraith torrent]

how do i fix this

idk what i did

solved it

very stupid solution

and problem

[distant hollow]

=== for text.

[unkempt warren]

Dock it and it should go away. Once it goes away you can undock it if you like. It's a bug.

[wraith torrent]

yea i solved it

its pretty dumb

[minor pollen]

🫶 Thanks

[frosty heron]

The triple one is probably case sensitive

[minor pollen]

So i just noticed that == does not even work on text only exactly and there is a other node == for case sensitive checking
It was just confusing because i saw there was a exactly option and equal check should be always exactly so why should there be a extra option but now i know what is going on

[frosty heron]

I just use the equal and call it a day

[digital valve]

How does this attribute go from 15 - 0 = 0?

[frosty heron]

Where does it say 0 in the game? You are just showing a picture of your default value

[digital valve]

the new variable or the updated stat when I dequip. it's weird it'll say 30 str equipped then dequiped 0 but back to 30 equipped

maybe my widget has a bug

[random pulsar]

I was thinking about abilities like in Elder Scrolls V,fire, electricity,dark energy etc.For example lets say we have a fire ability,how does it damage ?I can imagine how i could set up the niagara system or particle system ,but how does it actually apply damage?

[digital valve]

apply dmg function + trace hit or overlap?

[random pulsar]

Skyrim is the best game from my childhood,so i thought about structuring the m3chanics to better understand them

[random pulsar]

Trace hit-i imagine it ,but how overlap works,particles generate a domain and when you overlap with that domain you lose hp?

[distant hollow]

Turn a boolean on when you overlap, and run on Tick or timer to trigger the damage so long as the boolean is true

[distant hollow]

There is nothing leading into the Set mode

[random pulsar]

Yeah but i was thinking about the trigger box,it spawns ,how big it is,is it different for every particle system,does it stay with one scale or it inscreases...?

[distant hollow]

I guess that’s up to your design?

[jaunty coral]

Hello, guys. I have a question. Does this exist in Blueprint as well? Or it is just C++? I have tried searching for exact blueprint but have not found it. Does it have different name or something?

https://docs.unrealengine.com/5.3/en-US/API/Runtime/Engine/GameFramework/APlayerController/GameHasEnded/

[random pulsar]

Yeah there are multiple ways,but how it works in Elder Scrolls V,do you know?

[distant hollow]

Event End Play? Not sure if that’s what you are looking for

[distant hollow]

No idea

[jaunty coral]

Not quite sure they are the same but this seems to be usable in same case. Thank you for the info 😁 👍

[jade coral]

If I was to set "gamemode settings" in a lobby map, and then transfer to a map (and have the aforementioned "gamemode settings" be saved through the level transfer (and thus impact how the game starts and is played) how would I accomplish this?

[Using Advanced Sessions Steam for multiplayer rn]

[distant hollow]

Couldn’t you just use the same Game Mode for the new level instead of transferring?

[jade coral]

I thought it might be easier to have different gamemodes for the lobby where players connect/ready up and the actual game (so I could run logic/"start" the game on the actual begin play of the gamemode as opposed to basing it in the level, since if I have one gamemode for all the levels I can change the levels [as long as the logic works still])

I think I might just use the extra settings on the steam advanced sessions sessions to store the values [found this as an example]

Still open to ideas though, I saw the game instance as a possible solution but I felt like that might be a poor way of doing this

although ig your right actually

i just viewed the idea of having separate gamemodes as a possible flexibility option since if I want the lobby to be able to pick gamemodes I could just use them instead although the upside to having the settings all be in the session data would mean the search list for the sessions could show even more data (IE the map, settings, etc)

[distant hollow]

Not sure if it would be what you need but

[steady kindle]

Is it possible to make a blueprint and then move it's individual component seperately in a scene on an instance basis

[wraith torrent]

how do you

make the little grey container thingy

[frosty heron]

Press c for comment

[wraith torrent]

ok ty

[dire frost]

Yeah

Just double click the component you wanna move

[north lynx]

Hey everyone!
I have an unusual question. I would like to make an in-game game, that is, to implement in my first-person game the option to play a 2D arcade game. I know what I'm trying to achieve, but I don't know where to start, and I couldn't find any tutorials on the subject. I would like the player to then be safe, the game time would not flow, and the control would shift to the 2D character.

[swift kiln]

Hey I made a thing where actor will spawn at random location inside a box collision and I wanted to know how can I implement, that around for example my character there would be a radius where that actor just won't spawn

[tepid willow]

Hello, what is required to call the DelayUntilNextTick? I'm trying to make a macro library for just an object, but it doesn't show me that node, does anyone know why, and how I would get it?

[distant hollow]

I don’t think you can find that in macro library

[tepid willow]

Yeah, but why?

[distant hollow]

If I am not mistaken you cannot get any direct Delays for macros

[tepid willow]

I only see the TaskWaitDelay which takes the time as input

But I would like to wait a tick rather some amount of time

[distant hollow]

What exactly are you stuck with?

[distant hollow]

Maybe set it as a custom event in a blueprint instead of a macro

[tepid willow]

It doesn't work the same way

[swift kiln]

I figured something out. I just spawn actor before or behind player

[distant hollow]

One option would be to save the game then load up the 2D as another map

[distant hollow]

There would still probably be a chance that they spawn in the same spots

[swift kiln]

I mean I changed it so it wont be randomised in certain are, just before/behind player Edit: thats the old bp, I forgot to plug in location from break transform

[north lynx]

Yeah, that is possible
How could I not have thought of that 🤦‍♂️

Thanks 🧡

[grave relic]

Where can I find "Event hit impulse magnitude"? Went into the static mesh and took out "On Component Hit" but can't find anything relating to magnitude 🤔

[pulsar vigil]

Hey any idea why im spawning bp_actors and the same logic dont work on them if they are spawned or manulay placed in the level ?

[versed sun]

they are colliding with something and not spawning?

[pulsar vigil]

they are spawning and directly attached to another actor but they dont behave as intended

when i place them in the level they behave normaly

[distant hollow]

What exaclty is not behaving as intended?

[pulsar vigil]

like the behaviour is that when i trace hit them i can interact and attach them to my player

it look like the last actor spawned behave normaly

i was just hoping for a comon solution that* i didnt know but if nothing come to mind i m gonna do a better explanation with screenshot

[distant hollow]

So what is the abnormal behavior? Or what isn’t happening?

[pulsar vigil]

hmmm let me few minute i explain the entire thing

i want to test some thing before explaining everything cause i might take a lot of time to explain

My problem is because i use an event dispatcher that is binded with overlap box or execute over all the children that use the same logic multiple time and it fuck everything up i just tested to go in and out of every interact attempt and it work

[distant hollow]

So issue resolved?

If you have one collision for the entire sword then it will not distinguish which part of the sword is struck

That said, even if you have multiple collisions it would be counted as a same sword I think

You’ll probably need to have the parts as separate child actors so that they are processed differently. But I could be wrong.

[pulsar vigil]

no i m still trying to figure it out few testing and i come back here

[pulsar vigil]

resolved i dont realy know exactly what i did im to tired to remember my last 5 minute but it work lmao

[versed sun]

https://tenor.com/view/code-works-code-not-working-error-scaler-create-impact-gif-24991578

will area always be a cube ?

i would start with a Sphere Trace by channel, use a large radius, and the hit Should be the closest point

oh, hmm

ok, get the 8 corner points of your Rectangle Area
Loop thru the 12 Line Segments of the 8 Corners , and Find Closest Point on Segment
the lowest Return Value would be closest point

Draw Debug Box will help visualize it

[versed sun]

on 2nd thought, save the 2 closest points , and Find Closest Point on THOSE points

[trim matrix]

anyone know how I would do say a dash and sprint on same key but my enhanced input runs in c++

[digital valve]

It was connected in the test. It unconnected as ive been playing with it.

[untold rain]

i dont have any variables added to this blueprint , though had previously but deleted

[thin panther]

BP structs strike again?!

[untold rain]

what should ido now to fix

[frosty heron]

restart the project , open the bp again. you will get apromt that asked to delete the variable.
say yes.

If that fixed it, avoid future corruption by having 0 bp struct. Instead declare the struct in CPP and compile with the editor closed (apparently hot reload can cause the same corruption)

[spark steppe]

if you want to be on the "safe" side with BP structs you have to save all files, then edit the struct and just save the struct file, then restart the editor (without saving any other file it prompts you for)

[trim matrix]

in BP whats a good way to get the mapping context and maybe dynamically get the action so mapping and the associated key binding it has ?

[grave relic]

Does anyone know where I could start with taking damage on impact? So I have trees as in Valheim, when you chop them down they fall over. And I want it so if the player is not careful they can get hit and take damage. I don't know how to make this impact damage based on the tree's velocity and if it collides with the player. I got told about Event hit Impulse magnitude but could not find it

[broken wadi]

Setup a bool for when the tree is cut down. Check for collision with player and make sure cut down bool is true then use the tree’s GetVelocity vector and then the length of that vector to convert it into a float. Now you can use it for a damage value.

[spark steppe]

i think you could just use the hit event and multiply the damage with the velocity vector length, when the tree isn't falling it should return 0, so 0 * damage is no damage

[broken wadi]

Sure but maybe the character is already setup with some particles and sound effects whenever damage is taken? I suppose you could then just check the damage value to see if it’s greater than 0. I tend to just only apply damage when there is actual damage in the first place.

[gusty shuttle]

Hey guys, is there a tried and true method for using WASD in widgets using bluprints only?

Or rather, is there new techniques to do so?

[warm mulch]

Hello everyone, I have a pawn that is placed in a level. When I edit Base Eye height from the level, the value doesn't change and is reverted in the game while playing. But if I set value from the blueprint editor, the change is reflected in the game. Why does it happen? Also, I tried with a simple pawn and the same issue occurred.

[proper vigil]

Hmm.

Switch on Int.

[distant hollow]

Check if there is anywhere in your BP that sets the value when the scene starts.

[distant hollow]

What do you mean by “using WASD in widgets”?

[warm mulch]

I also thought that but I created an empty pawn blueprint and tried setting base eye height and still the same issue occurred

[gusty shuttle]

I mean, by default, Unreal uses the keyboard arrow keys to navigate through menus. I'd like to find a reliable way to either take the keyboard inputs and convert them to WASD or use some input system to navigate through the menus via enhanced inputs in the widget it's self if possible.

[grave relic]

Sorry I dont think I fully understood, tried this but I get not prints

[distant hollow]

Check the default value of the variable in the blueprint. Was that the value that it was reverted to?

[distant hollow]

I see

[warm mulch]

Yes. But why does it happen if I am setting in level then that value should be final.

[distant hollow]

Is this on the player or the tree?

[distant hollow]

Both the guns were changed to 64?

[warm mulch]

Yes in both the gun blueprint and the empty pawn blueprint where I am doing nothing.

[distant hollow]

Are the pawns child class of another class?

[trim matrix]

got a wierd issue happening

my Enemy is too good in terms of hitting me when it shoots at me

[warm mulch]

For gun blueprint it is derived from pawn class

[trim matrix]

I don't quite get how cause when it shoots it would be doing it towards the location it saw me rather then right at me

How quick would people say the bullets should be as at moment I have them at 1000 and it feels very unfair to the player at moment

[grave relic]

The tree 🙂

[distant hollow]

Are there any part of the codes that would alter this value?

[warm mulch]

No

[distant hollow]

Then your Component Hit is not firing, ie you are using a wrong hit/overlap event

[distant hollow]

What about the parent class?

[warm mulch]

you can see here the parent class is Pawn.

[distant hollow]

Where is the BaseEyeHeight variable in your design? I didn’t see it in the variables list

[warm mulch]

provided by default in Pawn class

[untold rain]

why is it like i cannot access custom event from widget bp from another actor compo bp

i can get the variable but not the custom event

[distant hollow]

Let’s take a look at that Pawn class

[stiff swift]

Mytho you'd need to add a reference id think to be able for the system to check your other actors BP so It can pull the event* but after thinking idk if you can do this

[untold rain]

refernce for?

[distant hollow]

Are you trying to access the widget via a blueprint, or the other way round?

[warm mulch]

The Pawn class is the class provided by Engine. I have not edited anything in Pawn class.

[distant hollow]

I’m not saying that you did; just needed to look at it to see if something is resetting it to default

My PC isn’t on right now so I can’t check

[untold rain]

i have this event and from an actor comp who is child of player character , i have a ref to this widget

i can only see the var

[warm mulch]

ok I will try digging deeper into the code.

[flint veldt]

Hey everyone, I need a desperate help to solve this casting issue, any input would be appreciated💫

Im using an encoder, trying to rotate a skeletal object, which is the BP on the right.
Im getting the value of the rotation position when i simulate it, but I cant make my object rotate.

Also, the value that I get has these gaps and weird breaks as you see in the thid image.

[distant hollow]

Drag out from As BP Main Player, not the target

[untold rain]

uh thats what am doing

[distant hollow]

Oh wait no

[stiff swift]

From viewport on your BP, add what is rotational component on the board for 300 pls

[untold rain]

umm i think i always get bad luck 😦

[lunar sleet]

What casting issue? There are no casts in your screenshot

[warm mulch]

There is a function.

void APawn::RecalculateBaseEyeHeight() { BaseEyeHeight = GetDefault<APawn>(GetClass())->BaseEyeHeight; }

that is getting called in void APawn::Restart()

[stiff swift]

I mytve striked neo with a chance to steal xD

[distant hollow]

It’s an Event, not a function hmm

Ok I’ll boot up my PC to test stuff

[lunar sleet]

Oh I didn’t see your reply but still see no cast

[flint veldt]

True, I tried to use casting node but i cant figure out a way to use it for my case.

[distant hollow]

That’s probably it maybe

[untold rain]

to me?

[distant hollow]

Yep, give me a few mins

[stiff swift]

Oh your right there is no cast BP character or object so that'd be a good start casting to whatever and then telling us what it's not doing

[untold rain]

its ok i will go with function instead of events

am able to access functions but not events

maybe its how it should work

[distant hollow]

No

Events can work

I think you are pulling wrongly

DM

@untold raincheck your DM

[stiff swift]

It's to early I shouldn't be giving advice such poor advice

[warm mulch]

Found out that APawn::Restart is resetting value. But why this is done? This will overwrite the values updated in the level.

[distant hollow]

You may need to figure out from the Pawn blueprint at what point in the codes is this being called

I’m not familiar with c++ so can’t help you there

[warm mulch]

its called before tick

ok thanks for the help

[distant hollow]

Alternatively

Rather than spending all the time trying to fix this

May as well just insert a couple more nodes to make sure it changes to the value on BeginPlay

That should override the reset

[remote meteor]

gamemode spawning player = restart player at player start = called APawn::Restart

[distant hollow]

Ohhhh

So essentially the pawns will be destroyed and respawned?

[remote meteor]

not exactly, if a pawn for the controller already exists, it will use it

[tight pollen]

every time I click on the widget and stop playing in the editor, Unreal crashes

why?

[distant hollow]

So in his case…?

[tight pollen]

someone can help?

[warm mulch]

Yes, I can do that and fix it but I was looking into why it is happening and resetting the eye height on restart.

[distant hollow]

So in short, the Pawn class is doing so, and likely is due to what IAsaka quoted

[remote meteor]

APawn::Restart is setting BaseEyeHeight to default, if you edited the value from the level editor (instance editable) it would be overriden by the Restart function

since the way GameMode use to spawn player when you press play, is the same as restarting the player

the Restart function is being called

hence it is reset to the default values

[versed sun]

so, when you press the button, you make it simulate pressing the button, which in turn simulates pressing the button that simulated pressing the button...

[warm mulch]

In that case, the value should not be visible or editable if it has no effect while changing in level as it is confusing.

[remote meteor]

yeah thats one part Epic did not do well

nontheless, either you create your own variable, or override what APawn does to the variable

[warm mulch]

yes

[remote meteor]

sometimes unreal is just too big to have everything make sense...

[warm mulch]

yes I understand

[remote meteor]

so when i identify stuff that epic did not do well, i just do my own or edit theirs(by extending class)

[warm mulch]

I will do the same 👍

[crude dew]

Q : Will Random fire twice and provide 2 different index's from this code or will it print out the random one it chooses from the spawn points please?

Just want to make sure that I am printing out the correct "random" index from this.

[versed sun]

Location and Report will be different

[crude dew]

Ah damn so i,ll have to run location throuhg and do a FIND INDEX on the array to get it,s correct index then

[versed sun]

You would want to get a random Index and save it , the Get from array using index

Or your way is same

[crude dew]

Thanks !

The updated version

[versed sun]

will still be different

[crude dew]

holy XD

Ahh each wire off the Random provides a new "random"?

[versed sun]

Random>Set Variable> use the Variable

[remote meteor]

gotta save the output from the random first

also

save the index

not the object

so you can get by index easily

[crude dew]

Ok thanks!

Think this looks better now.

[paper gate]

Probably a compelte newb question, but I gotta know. Is there a better way of doing this? I am trying to clamp player's -x velocity. I am converting it to local, clamping and then converting it back. It works just fine, but it seems ridiculous to do it this way instead of something simpler. Is this the way you all would do it?

[foggy escarp]

for vectors, you can clamp the length without breaking and making it manually.

[spark steppe]

he want's to clamp ona specific axis

in actor space

[foggy escarp]

oh, missed that.
yeah, this is basically how I'd do it.

[unique silo]

hi folks, anyone have a quick idea on how to round a float with 3 decimal slots to a float with 1 decimal slot? So that 10.XXX gets "rounded" to 10.X ?

[versed sun]

in text form or as a float ?

[unique silo]

preferrably both. but text form could work as well

[versed sun]

To Text (Float) has a dropdown with some settings

[unique silo]

omg you are a lifesaver

just out of curiosity, if we wanted to do the same for actual floats, is modulo the only way?

[versed sun]

If you need to Round a float to a certain decimal point , i use this
Step = what you want to round to, so your 10.xxx rounded to 10.x you would use step = .1

[unique silo]

amazing thank you so much!!

[paper gate]

I remember snooping around some in-built chararcter blueprints and remember an "if" blueprint or something like that, it took a boolean expression as input, along with true/false arguments (floats, I think) and outputted them based on the bool. Any idea what that could've been called? I couldn't find it, so am I misremembering something? Was it deprecated? Was it custom for that script? I can't seem to find it now

[versed sun]

Switch , or Select ?

[paper gate]

Select, thank you

I genuinely remeber seeing it under the name "if" somewhere

no idea

thanks

[gusty shuttle]

Hey guys, is there a way to push a key (WASD) and virtually press up, down, left, right arrow keys on a keyboard? Essentially for widget navigation

[gusty shuttle]

I need to take a keyboard button press (WASD) and simulate it pressing press up, down, left, right arrow keys on a keyboard

Are there any keywords or anything guys? Anything?

I need something like this. Is there an alternate method inside a widget (not widget component, nor C++)

[abstract mango]

I wonder.... would someone be able to help me rebuilding these Car Physics and the system for the Cars?
https://youtu.be/mzhOhWLj85A?t=304

all of my previous attempts failed, even setting up the vehicle with the base chaos vehicle stuff was horrible, and with the advanced vehicles plugin it even was an disaster, nothing really worked when I tried

[copper tree]

If you're using 5.2 or later, you can use Enhanced Input to map that for CommonUI: https://docs.unrealengine.com/5.2/en-US/using-commonui-with-enhnaced-input-in-unreal-engine/
If you're using something older, not too sure

[hot inlet]

Hello
How can i change als (advance locomotion system) camera spawn location??

[gusty shuttle]

I am indeed, however, I don't understand how I can use that within a widget though. I'm sure I could, but at this point my main issue is the native navigation system Unreal has. I need to simulate pressing buttons...If the enhanced inputs can have keyboard W, but have a modifier of it press Up then we're in business

[gusty shuttle]

It's inside the camera blueprint

[hot inlet]

I cant find it

[gusty shuttle]

Still my focus won't change in menu. I'd need to still press a button for it to fake press it

[copper tree]

I guess it depends on why you need "Up" or whatever direction to be pressed to determine what your best solution is. Just trying to navigate, or are you doing something more complex in widget?

[gusty shuttle]

Thanks for responding. Firstly, I didn't implement CommonUI upon further reading, just default UE5.3. All I want to do, is press a input (w, a, s, d) and convert that press to a simulated up, left, down, right press.

Why? Unreal has it's default UI navigation set to use the arrow keys. There is away to switch it via C++ but I'm not versed in it. I'm trying to find a work around

[red briar]

Hey, i'm not really sure where to put this, as it's to do with cameras but heres the deal:

How can I make Legacy Camera Shake predictable? As in, I don't want it going in random directions and making the player throw up, lets say I want to roll the camera left and right gently, but not randomly, the same in both ways. How can I do that?

[copper tree]

Okay yeah I think the BP is the way to go if you don't want to tinker with cpp. You may be able to use the Set User Focus node as a workaround?

[gusty shuttle]

Aye, I've been using SetKeyboardFocus and it usually works. Seems like when I muck around with SetUserFocus, things get wonky haha. Also, how do I tell it to set user focus on the button above or below right

[copper tree]

Array of widgets, and increment/decriment?

[gusty shuttle]

Aye, I've done that before too. You set up a int for which row. I was trying to avoid that haha

I'm sure this is possible. It has to be. If It was a VR game, they have a super handy node for widget components called Press Key haha

[copper tree]

What was wrong with the BP example you sent in the first message?

[gusty shuttle]

That node won't work because it needs a widget interaction component (typically used for VR)

I'm just in a regular widget

UserInterface

[copper tree]

Ahh, okay I see. Yeah, I think unless you go the C++ route you won't have a super clean solution, but I'm sure there's some way to override the default navigation 🙂

[gusty shuttle]

Oh there is for sure. Probably super simple too. It's one of those things where I'm either over thinking it, or there's a node string that can easily be put in

Either way, if I find a solid solution to this, I'll make a video and post it on the forums. Seems like their is a huge search demade for this topic, yet the only major fix is through C++

[idle monolith]

Basically I need some help to figuring out how I can't make this damn character switch functionable
I have tried everything, even redoing from scratch the BP that see in this orange Comment, but nothing at all.
So...pliz help!

[random pulsar]

when i press r i want the door to slowly go down ,the timeline has float track from 0 to 2 sec,now when i press r the door teleports from 130 units to 0 units z axis,why?

[hot inlet]

How can i make a camera actor for als??
If i dont make one, unreal make cameraactor_0
But if i make camera actor, Unreal make cameraactor_1

"Sorry for bad english"

[crude timber]

Hi everyone ! Are the Debug Traces bugged in 5.3.2 ? When turning debugging ON to see the line trace or shapes, it is not placed properly and my camera shifts location for some reason.

As soon as I turn off debugging, there are zero issues so I don't think it's something I did wrong. Even the Hit locations are correct andd accurate, it's just the debugging that shows up wrong

[round marten]

why isn't this working

this is in an animation blueprint

coming off an update animation event

same issue

[crude timber]

I don't think you can get location that way, you have to reference from your actual player actor

[round marten]

i don't want to cast to my character every tick

[crude timber]

you don't have to

[round marten]

i tried it in begin play and it didn't work

[crude timber]

no casting needed

At Begin Play, "get actor of class", pick your character blueprint, set it as a variable. Then, reference that variable and get actor location

[round marten]

ok i'll try that

[crude timber]

I see you named your location variable as "player head", but keep in mind that it will not save the location of the head but rather the root of your actor

You'd have to get a reference to the actual head bone from the skeletal mesh to do that

[round marten]

i know i had a socket setup and everything rn i'm trying to get this to work first

update

didn't

didn't work*

[crude timber]

it's not setup properly

What you are doing there is getting the head bone location only once at begin play, then updating every frame to that same original location

[round marten]

that's what i assumed

at first

[round marten]

that's why i tried this

and it didn't work

should i use the get actor of class in the update event?

[crude timber]

Set the skeletal mesh as a variable, then reference that variable in your update anim graph, then get socket location

[crude timber]

never, it will eat performance

Never Cast or get classes every frame

[round marten]

like this?

[crude timber]

should work, hard to say without context of your system

[round marten]

here it is in begin play

[round marten]

just a regular first person template

[crude timber]

you can print a string or draw a debug shape to test if your location is properly saved

[round marten]

(don't laugh at my model) here it is working fine

but it's giving me an error at exiit

[crude timber]

What's the error ?

[round marten]

access none trying to read properly bla blabla

this play head variable

does it need constant information?

[crude timber]

If it worked I guess it couldn't access it only for a few frames at the beginning

[round marten]

one thing i know for certain, is that this wasn't an issue in unreal engine 4

[crude timber]

you could add a Is Valid ? for your skeletal mesh before setting the Player Head variable

that should get rid of the error

[round marten]

you're right, it only gave me the isue once

that could explain it

alright, thank you @crude timber

[green solar]

can someone help me do simple math in blueprint?

i want to get the acotr forward vector
if the x is positive and the y is positive make this vector [1,1,0]
if the x is positive but the y is negative make this vecotr [1,-1,0]
etc

[gusty shuttle]

I found a work around, I found this AMAZING plugin that does the job superbly. It's a free plugin called Virtual Input. Frigging would of saved me HOURS if I found it earlier

https://www.unrealengine.com/marketplace/en-US/product/virtual-input

[copper tree]

Oh that's sick! Exactly what you needed

[crude timber]

Getting the forward vector isnt hard, let me screenshot my setup

[green solar]

thats the easy part

its just a function

the hard part is the math

[crude timber]

I'm not sure what problem you have then ?

[green solar]

cus idk how to do it

i want to make a vector where x is 1 if the x in the forward vector is positive and -1 if negative

and the y is the y in the forward vector , is 1 if its postive and -1 if negative
the z always 0

[crude timber]

I'd use Compare and Branch nodes

[green solar]

how, if it was writing on a language this part would be easy
but in blueprint idk how to do it

[crude timber]

I'm in UE right now ^^ let me check and screen

[green solar]

for example here

what do i do

[crude timber]

might not be the best way but you can try this

But honestly you don't even need to do that, you could just Round your vector values to an integer

[green solar]

-0.2 would round to 0

and i dont want that

what SET block is that?

[crude timber]

just a vector3 variable I had in hand

[crude timber]

ah, I see

You could also just multiply your vectors by a high value like 10, and clamp the result from -1 to 1

[crude timber]

This works @green solar

[fair magnet]

Is DayTime more like a gamemode or gamestate thing? I'm unsure lol

[green solar]

thx

also, why does launch character function different on ground and on air

and it also does kind of a curve

[unkempt warren]

Game state

[fair magnet]

Ty

[finite hearth]

On game mode construct, I get all actors of X and add them to an array.

This works fine on my other level, but I created a new level and now the array is returning empty.

Things I have checked:

• I have the correct gamemode set in the level override
• I have several X actors added to the level in the viewport

I am a little stumped on this one.

[lunar sleet]

Where is this array saved ?

[finite hearth]

The array is saved on the game mode

And called on "event handle starting new player"

So in theory, it should go construct (set array), then call the array after. Right?

But putting a print to loop the array at construct shows its empty. It feels like "Get all actors of class" is not grabbing the actors that I dropped on the viewport.

[lunar sleet]

How does it show it’s empty?

Nothing prints ?

[finite hearth]

nothing prints from a for each loop

[lunar sleet]

Have you tried moving it to begin play?

[lunar sleet]

And are you sure the print itself fires?

[finite hearth]

Will try now!

I put a print on the "completed" for my for each loop, the completed fires but the loop body does not, I suspect because there is no item in the array.

Will try moving to begin play.

Same result on begin play: empty array

[lunar sleet]

Leave it on begin play and use a breakpoint. When it drops, hover over the array output pin or its counterpart on the for loop

That should tell you for sure what’s in it, if any

Also can you show a screenshot of the current code

[finite hearth]

I'm very new to unreal and don't quite know how to use breakpoints.

[fair magnet]

Why can't I set the timezone offset of my datetime variable? It just keeps jumping back to +0100

[lunar sleet]

Select node, hit F9, hit play. You might need to step over to the next node to see the pin hovering results.

Gtg but if you can’t figure it out, post a screenshot of both sides in here (level that works and one that doesn’t. And double check your world settings for the new level (not project settings) are where the GM is overridden

[finite hearth]

Will do, thanks for the help!

[finite hearth]

I have double checked the GameMode Override & selected GameMode is the same between levels

[sonic crest]

Show variable type

Try make for each then create variable from the blue pin, then change it to an Array

[finite hearth]

Here is the var type

[sonic crest]

Is BP Player Start Camp a child of the BP Player Start?

[finite hearth]

BP Player Start Camp is a child of Actor

[sonic crest]

Try to change the class to BP Player Start Camp

[bleak kelp]

is that what the get all actors of class is set to?

[sonic crest]

From the Get all actors of class

Because it's showing for the BP Player Start. And since BP Player Start are BP Player Start Camp are not related, that can be to why it's not connecting since they're different

[finite hearth]

It's a bit cut off in the screenshot, but the Get all actors of class is set to "BP Player Start Camp"

[bleak kelp]

you could do a "is array empty" check and branch off that on the get all actors of class node to check if it's picking anything up

[sonic crest]

After the loop, try manually adding to the Array?

Get array
Add
And hook up from the loop

[finite hearth]

I tried to manually add, the issue is get all actors of class is empty.

[sonic crest]

When you print string from the Get All Actors of Class, do you get any output?

[finite hearth]

the print string will fire, but the contents (array elm) is blank

[sonic crest]

Try to attach it directly to the loop, then on Loop Body, print the Array Element

[finite hearth]

^ that's what I tried

[sonic crest]

Hmm

[finite hearth]

So strange, this logic works fine on the other level

[sonic crest]

Double check with the map, see if you're using the default spawn or the camp one

[sonic crest]

Not new, I once had an issue with a boolean actually being inverted without inverting it. Thought a bug will get fixed but nope, still there. Kept ity

[sonic crest]

If you have them set correctly, try adding a "delay until next tick" on your begin play

[finite hearth]

Do you mean, check if I dropped the correct BP Player Spawn Camp in the viewport? Or are you referring to a spawn setting?

[sonic crest]

Yes, weird.

[sonic crest]

Try this, if it didn't work, restart the engine if you haven't yet

[finite hearth]

Woa! The delay until tick fixed it.

What does that mean? Too much stuff being processed at once?

[sonic crest]

Glad to hear it got fixed, and depends which is being fired first

BeginPlay isn't always first to launch

Like when working with AI. BeginPlay doesn't start first

[finite hearth]

Should this live in the construction script then?

Ah, there is no tick to delay in construction..

[sonic crest]

I wouldn't use construction scrips unless if I wanna debug something.

Construction Script runs constantly but only in the editor and not in game

[finite hearth]

Thank you very much for the help!

[sonic crest]

Happy to help)

[solid vault]

why is it only printing "2"

when my array has 2, 4, 6, 5, 10

[bleak kelp]

other way round, the top pin is what you're applying the modulo to

[pastel fable]

X % 2 is different of 2 % X

% (mod) is the rest of the div

[solid vault]

oh

oh wait is it doing 2 % X

and not X % 2 ?

[solid vault]

okayy

[lime crow]

If I want to store a money pick up across my game I want to set it up in the game instance right? But really the logic needs to be the player character for overlaps and stuff, is it enough just to make a money pickup function in the BP player and call it from even init from the game instance?

[eternal cradle]

you can store the value in the gameinstance and/or just save&load while changing levels

it does not need to be specifically INSIDE the game instance. you can store the money value anywhere, but send it to the gameinstance when required (while changing levels for e.g)

[lime crow]

Yeah that makes sense, then just call it on each level blueprint?

[faint pasture]

Don't use level blueprints

especially not for keeping score

or pickups or anything like that

[mellow pike]

so I got this logic for selectively rotating the camera when some switch is triggered, and it works fine.
however after some testing I found it only rotates right to left but I will need to flip that from time to time

how do i invert it ?

(tryed setting the target value from -90 to 270 and other things like that , but no change )

[distant hollow]

Multiply -1?

[mellow pike]

somting like this ?
no change

[mighty crown]

I'm having issues with my variables disappearing if I use common UI variables in my UI widgets that are being referenced by my character. This is happening after I restart my editor.

If I create a UI widget that isn't being referenced by my player char then the variables don't disappear after I restart the editor.

Been trying to figure this out for a couple days. Any advice?

[mellow pike]

this made a change but it was triply

sorry Copyrighted , I have not seen that before

[mighty crown]

Ah I see this in my log when I boot up the editor. Maybe this is a part of the issue

LogLinker: Warning: [AssetLog] C:\Users\tyler\Documents\Unreal Projects\WeatherReportGame\Content\UI\BP_RTSHUD_ResourceBar.uasset: VerifyImport: Failed to find script package for import object 'Package /Script/CommonUI'

[mellow pike]

got it thanks
guess I don't got it lol

[mellow pike]

that is likely , "Failed to find script package" that is odd you may want to try reimporting the plugin
but that could mess up your BPs that were using it ....I will try to look up what that error might be about

[mighty crown]

I disabled and reenabled the plugin but still encountering the issue. Yeah Im doing some searching

[distant hollow]

What do you by “triply”?

[mellow pike]

it was rapidly snapping not good for epilepsy lol
I do have it fixed now trough

[mighty crown]

I fixed it. I changed the loading phase of the common UI plugin to PreDefault from Default

[mellow pike]

that is odd but glad you found it

[quartz gate]

Hi gang, new here, and quite new to UE as well. (Never made a game in my life 💀)

I'm trying to start somewhat simple. I want to develop a simple dice rolling game.

I followed this tutorial (https://www.youtube.com/watch?v=iqscP1aRmbE) and duplicated the dice BP 6 times to make it roll as a standard D6 set.

So far, I've got the rolling down, but getting it to show all 6 dice values is proving to be tricky. I'm just not sure I know of the proper methods to do so. Would appreciate any help I can get.

[main lake]

Any pro at Voxel Plugin who could tell me if it's possible to use that plugin to make voxel builds that aren't terrain. Because usually people use that tool to make terrain and was wondering if with that tool it's possible to create builds like in minecraft (houses, farms, etc...) that aren't terrain like this image. And by that I mean being able to do that in editor, by placing block by block and having it make the necessary optimization for voxels (not rendering hidden faces, greedy meshing,etc...)

Please ping me if any answer 🙂

[lean flax]

What do you mean you can't get it to show all 6 dice values?

[quartz gate]

So, according to the tutorial, each dice face has a box collision. I have another box collision setup that checks if it is hitting a certain face and sends the face value to console. Right now, it only shows one die's value, I can't get it to show each individual dies face value, it only shows one and I'm not sure exactly which one it is showing. I hate to make you watch the full 20 minute long video, so tell me what you need in order to understand the situation and I'll do it 😄

Let me see if I can send you an example of what it is doing currently.

[lean flax]

Show me how you are getting said dice value (the only one that prints)

[lean flax]

Also in your original message you said you duplicated the D6 BP, did you do that in the editor or in the content browser?

[quartz gate]

Content browser

[lean flax]

Your problem might be there

[quartz gate]

I have a BP named Side_BP. It is a big box collision. It is positioned just above the dice model, so it will only hit the box collision on the dice bp.

The image provided is the Dice BP Event Graph. This performs the random rotation and positioning of the dice in addition to checking if the dice is rolling.

The next image I am about to provide is the Event Graph for the Side_BP.

[faint pasture]

That's a pretty bad tutorial then

[quartz gate]

Honestly fair enough. Couldn't really find any solid tutorials online.

[lean flax]

If those images you sent are straight from the tutorial I'd say you watched a pretty bad one, yeah

[faint pasture]

Some math based on the dot products of Dice.Forward, right, up vs global up vector (0,0,1) will get you on the right track

[quartz gate]

Yup, no real modification. Now granted, this tutorial was for only rolling one die, and I need 6. Me being absoultely brand new, I figured, duplicate and see if it works 💀

[faint pasture]

Are those 6 child actor components? What are those 6 things

[quartz gate]

Those are all box collisions on each dice face.

[faint pasture]

Naw don't use collision for this

You want to roll physical dice -> get a number 1-6 out right?

[quartz gate]

Precisely. I'll need to define rules for it later, but as of right now, I just want to get the number

[faint pasture]

You could just add a scene component to each face and check which of the 6 scenes has the highest Z

that'd be a quick and dirty way to do it

put the 6 components in an array, select the one with the highest Z, it's index + 1 is your result

[quartz gate]

Ohh okay, should I keep it as 6 different blueprints or should I consolidate it?

Honestly, I hate to bother, but I'd need some sort of visual on how to do what you just said. Like I said, I strictly followed the tutorial and slightly messed around a bit. As far as everything else goes, I have no idea what I'm doing.

I appreciate all your advice

[faint pasture]

1 bp

quick and dirty

You could do it with your current colliders, colliders ARE scenes

you just don't need the collision-ness of them for this

[quartz gate]

Dude you're frickin awesome. Thank you so much man.

[faint pasture]

Had a bug lol

WHEN to get result will be harder, if you're using physics you can use the On Sleep event probably I guess

[quartz gate]

That's awesome. Thank you man. So, just to clarify.

I have a character that originally was calling the rolling event in each blueprint.

So should the Event BeginPlay code you provided go there?

And the rest below is what goes in the Dice BP? Sorry, I'm confused lol

[faint pasture]

This is just to set up the array and a function to check the result

When and how to do your roll is up to you

idk anything about your rolling system, just that the CheckResult function will return a number when you call it based on which face is facing most up

[quartz gate]

Okay, so all of this should be in the dice BP? And the scenes are the faces of the dice?

My rolling system is barebone. All it does is it randomlly sets the rotation and applies an impulse. You can see it in the image I provided.

I'm just trying to understand how it should all work with each other.

Forgive me for being slow lmfao

[faint pasture]

I'm assuming your dice is 1 static mesh. Just put a scene in front of each face like your colliders are right now

[quartz gate]

You'd be correct.

[faint pasture]

it's just a thing you can get the location of to see which one is highest in Z axis

[quartz gate]

Gotcha. One second here while I do that

[quartz gate]

Hey, what's the SET node named in this image?

[faint pasture]

just setting an array

[quartz gate]

👍

[radiant bear]

Is this node removed in UE 5.2.1?

[frosty heron]

it's called leader pose now

[radiant bear]

ohh

[frosty heron]

afaik the change is from UE4 to Ue5

[radiant bear]

i saw it was in UE 5 documentation

thought it is removed in 5.2

[frosty heron]

if you use UE5, look for leader pose

[radiant bear]

thnx!

[frosty heron]

generated docs from Unreal website is not reliable

[radiant bear]

i see

will keep this in mind

[distant hollow]

It’s almost never helpful at all lol

[pure salmon]

What is this for?

never noticed it before

[versed sun]

never saw it , doesn't ring a bell

[edgy ingot]

Like repnotify maybe but yea never saw it
