blueprint

[runic urchin]

I currently can't get my print statements to do anything

[gusty axle]

Oof no, separate the nodes, just attach On to overlap and Off to end overlap

[spark steppe]

which blueprint is this? camera or trigger zone?

[runic urchin]

Actor blueprint

[spark steppe]

of what?

[runic urchin]

It's just an actor blueprint

[spark steppe]

...

from which actor?

[gusty axle]

If you have a defined actors array
Create a blueprint interface, make a function, add interface to an actor you want to receive input in, create an event from interface, then in player actor make a key event, get actors array, create interface's "message" function and plug the array into it

[spark steppe]

your player?

[runic urchin]

I do not have a player, it is a separate actor blueprint that will go into multiple levels

the idea is to have a have my camera go inside a trigger zone and turn lights on

[spark steppe]

yea i got that

[runic urchin]

and then while outside the trigger zone shut lights off

[spark steppe]

but that overlap event that you defined there, only triggers if that actor blueprint overlaps with the trigger box

so you rather want it either on the trigger box, or on your camera

[solemn crescent]

I’m new to Unreal, so it’s going to take a moment to research those approaches.

The idea is, once those actors are in the array, I run the BP within the pawn bp-actor and grab the refs from the array?

[runic urchin]

@spark steppe is there not a way to get the camera and tell it when it overlaps the trigger box to turn on and off the lights

[spark steppe]

see, i would make an actor blueprint with the collision box

which handles the overlap event

[runic urchin]

I'm doing that

[gusty axle]

Blueprint interface is like runs the function if that actor has implemented interface and the function and you don't need to cast to call an event

[spark steppe]

you said that your BP is just an actor blueprint, when i asked you if it belongs to the camera or trigger zone

so the trigger zone is part of that blueprint?

[runic urchin]

Yes

[spark steppe]

ok

select the trigger zone component, and in the details panel search for the collision settings

and post a screenshot of that

[gusty axle]

To make the stuff works you need
2 actors: actor A that is a box fox example, it has begin overlap and End overlap
Actor B is a player or any other actor

If actor B overlaps actor A it will execute overlap begin/end events in actor A

[spark steppe]

there should be more settings

e.g. generate overlap events

and a list of checkboxes which tell how it handles collision

e.g. ignore / block / overlap

[spark steppe]

ok that looks fine

now the same for the camera please

[gusty axle]

I don't think you can use overlap events with a camera

Camera have no collision

[runic urchin]

camera is not in the actor blueprint, I'm calling it on eventbeginplay

[spark steppe]

well, if you select it in the world outliner you should be able to find the settings

or do you spawn the camera from code?

[runic urchin]

Camera is in the persistent level

[spark steppe]

the checkboxes aren't there?

then shameless ariral was right and cameras don't have collision stuff

so you may have to wrap it in an actor

[runic urchin]

hmm okay

[gusty axle]

cameras have no collision

[spark steppe]

and give it some collision

[gusty axle]

Use capsule components or smth

Or sphere component

[spark steppe]

yea, or attach a sphere collision directly in the level, that might work, too

[runic urchin]

I was just about to say attach an empty actor to it?

[gusty axle]

Make a pawn actor, add camera to it and attach the sphere

[spark steppe]

i would make an actor with the camera and sphere collision in it

that way you can check if it's that specific actor class

[gusty axle]

Doing stuff on the level itself is kinda dirty

[runic urchin]

I'll look into adding it into one of my blueprints driving camera mothion

thanks!!!

[spark steppe]

anyways, once you done that, the sphere collision should have overlapping collision too

then your event should fire on the triggerzone

[solemn crescent]

Phone-bat died. Thank you for your help. Digging into it now.

[gusty axle]

pls does anyone have any idea why that happens?

convex collision doesnt work either

[proper dagger]

Hi! How would I go about making a moving platform that uses interptomovement not stop when the player sits in front of it? Thank you!

[willow gate]

@gusty axle @spark steppe Thanks from earlier. I've got a nice little Map based inventory now that pulls data from structs via data table. Shoulda just gone with this from the start. I'll def be using maps from now on instead of arrays so cheers Ben.

[gusty axle]

I just installed ue4.27
I had Render Target and transparency doesnt work anymore for some reason

[silent pilot]

Any tutorials on how to make HUDs in which text can track a variable?

E.g. a HUD that shows your coordinates

[lime moat]

I'm having a strange issue with using the random float in range node. It works great if I'm using magic numbers, but as soon as I turn it into a variable, it goes outside the min/max values I'm setting as a variable. Anyone have any ideas what might be causing this?

Right now my min vertical range var is set to 0, and max is set to 1, you can see in the print string, it is not setting the float in the range I am setting

[gusty axle]

Set the text component to variable, theres a checkbox at the top

[gusty axle]

Its probably because min and max range variables are changed at runtime

[gentle urchin]

^

[silent pilot]

That's what I did, but where do I tell UE4 which variable to put?

I couldn't find any tutorial about that

[gusty axle]

Use Set Text node

[obtuse herald]

Event graph

[gusty axle]

And you can convert float to text for example

[lime moat]

How could it change at runtime? I have no other nodes setting the variable, its only set upon creation

[trim matrix]

Hey so i am working on an character spin thing that spins the character when i press right click.
It works perfect but the camera needs to be at the exact point and not rotate with the pawn

[obtuse herald]

Use a camera that is not attached to the pawn

[trim matrix]

Do i need to spawn it seperatly

[lime moat]

You're right. I had my variables exposed and had them changed outside BP 😛
thx for pointing me in the right direction!

[obtuse herald]

That or place it in level

[trim matrix]

so then i need to delete that one that is attached to the pawn right?

[paper galleon]

If the camera comes with the character. You can set it to use pawn control rotation. It shouldn't rotate with the character then.

[trim matrix]

that is what i tried and it just teleported inside of the pawn

and spins with it

[paper galleon]

Yeah. It must still be receiving input.

[paper galleon]

You can do what was suggested and use another camera

[obtuse herald]

You don't need to, but if it's a separate pawn only for the lobby I recommend it

[trim matrix]

that is with the one camera

[obtuse herald]

yeah untick use pawn rotation

[trim matrix]

i did that

its not using the seperate camera

[obtuse herald]

oh yeah, also change auto activate to player 0

[trim matrix]

ah

yeah i got it

[trim matrix]

yoo works thanks

[obtuse herald]

you're welcome

[trim matrix]

can i get like unlimited turning for that it only goes to the edge and hides the mouse cursor

[solemn crescent]

I’ve gathered docs/tutorials on all of theses steps.
The object oriented aspects make sense.

I’m not sure where to stage things.
“If you have a defined actor array”
Where do I instantiate this so it will be available across levels etc?

Or do I instantiate it in a pawn along with the key event nodes?

[obtuse herald]

GetPlayerController -> bShowMouseCursor = false when you start the rotation.
GetPlayerController -> bShowMouseCursor = true when you stop the rotation.

[lime moat]

Anyone know if its possible to set constraints on an actor within BP? I haven't found any nodes, and when I search online, others have the same problem.

[gusty axle]

"defined array" i mean an array with actors

like you added stuff in it

just plug the array variable into interface "message" function

[solemn crescent]

Sure, do create that array variable in the level_bp or?

I’m not sure where to stage things.

[gusty axle]

and it will "activate" the functions in these actors

[silent pilot]

Event graph of what? I'm using a Widget Blueprint that is constructed by a HUD

[gusty axle]

anywhere you want, in player or gamemode

depends how important these objects are

if its like 5 objects you can make an array in player, if theres alot of them and need to access from many actors make array in gamemode

[solemn crescent]

Ideally they launch at the start and persist across levels.
I’m brand new to unreal and have only worked with the level_bp successfully.

[obtuse herald]

In the widgets event graph. You need a reference to the actor of which you want to access its variables tho

[solemn crescent]

It’s only two objects.

[gusty axle]

two objects that always on the level?

they not getting destroyed or spawned?

[solemn crescent]

Yes, a CineCamera and Plane.

The CineCamera is a child of an nDisplay, which prevented me from making it a blueprint_actor and running the code from there.

This could also make no sense, I barely know what I’m doing.

[gusty axle]

Well you can make 2 variables inside the player

[trim matrix]

I did that already and disabled the input after release

[gusty axle]

ddefine these 2 variables from the level, and plug these 2 variables into interface message node

[solemn crescent]

Ok, didn’t know I could access the player or make variables there. That sounds interesting.

[silent pilot]

I don't see any event graph for the widget :(

[twilit anvil]

Hi, anyone could help me with issue with AssetGroupCultures? I set my text language and my audio language using setup as below on the screen and the issue is setassetgroupculture almost always is ignored - it only happens to work the both settings are set to the same calture and when i restart editor - but even that sometimes does not work once, need to switch those multiple times.
I am pasting ma code for changing text language, audio language (asset group), my defaultgame confing any my usergamesettings in packaged game (shipping). I tried everything and i feel helpless now with this, i am pretty sure it worked few months ago but now i just question if it ever worked in the first place.
The text only translation settings work flawless and at runtime without need to restart the game - only the assetgroupculture changes do not seem to work most of the time.
I use UE 4.22

[silent pilot]

nevermind I found it

[gusty axle]

oml cultures i had quite some troubles with it

i would help you but i have to sleep f

sry

[solemn crescent]

Oh interesting, so in the level_bp(or player) I create a variable of type CineCamera and another of Plane and then access them that way?

Ahh, 💤

[gusty axle]

inside player

only player with controller can send key events

make 2 vaiables in player actor and set these variables

make them public first

and you can select objects from the scene

my brain melts i cant speka english i go sleep

[solemn crescent]

Sleep well prince 🤴. Muchas gracias!

[silent pilot]

k so my HUD needs the coordinates of my pawn, how do I do that?

[gusty axle]

getPlayerCharacter > getActorLocation

[obtuse herald]

Ok then try this:
On rotate start: GetPlayerController -> SetInputModeGameOnly
On rotate end: GetPlayerController -> SetInputModeUIOnly

[trim matrix]

i dont know why but on false its not working properly with the only ui

Works perfect with that thanks a lot

[obtuse herald]

oh yeah, use.. ah you found it

[trim matrix]

yeah xD

[signal delta]

Hey guys questions, whats the best way of codding something as a Tell tale game, would it be better to code lets say a whole level in one blueprint with delays and animation sequences and choices with branches, or shold i takkle it differently, as i m having problems with animations playing at start yet when i cast to them they dont play again

[twilit anvil]

Understandable, if you would find some time later I would appreciate this a lot. I also am dead today, 12 hours of dealing with issues all day and I am devastated as I run into this dealing with something else, those problems really like to emerge in packs heh

[gusty axle]

doing-stuff-for-12-hours-straight gang

[trim matrix]

The errors are stacking if im doing it with the input mode variant.
I cant click on Buttons anymore 😕

[gusty axle]

🗿

[trim matrix]

🤨

[twilit anvil]

The worst thing for me when some current stuff happens not work and when I debug it I find that some other important older stuff also is broken

[gusty axle]

Same lmao

esp when i migrate to new engine version and it broke my project

Render targets have no opacity on ue4.27 fsr

And background is red asf my eyes are melting

[twilit anvil]

I don't even do that xD this project is on 4.22 still for a reason heh

[obtuse herald]

hmm.., try setting the widget to focus to your lobby widget

[silent pilot]

My main character is a sphere, that inherits from a pawn, with some features added, like variables. How do I access the variables from another object?

[gusty axle]

Im on 4.25

[trim matrix]

idk why i tried btw reference to self and didnt work either

[gusty axle]

And procedural mesh component have no collision this component sucs i have so much troubles with it

It works 50% of a time

[obtuse herald]

You get the reference when you create the widget

[twilit anvil]

I use 4.27 for other project which is fairly new, but I think this is offtopicing here as people need help with issues

[trim matrix]

so... im not understanding

[gusty axle]

Like look lmao
https://media.discordapp.net/attachments/225448446956404738/973264228393828422/unknown.png

Its supposed to be black

But its red and its killing me

And post processing is weird too, it's too bright even on low setting

Ue4.27 is weird

[obtuse herald]

The Create Widget node that you use somewhere returns a widget reference. Plug this reference into In Widget to Focus

[trim matrix]

the reference is in the gamemode of my game

[obtuse herald]

Yeah, save the return value into a variable

[silent pilot]

I'm still searching, if anyone's got the answer...

[gusty axle]

You can either do Cast To or use blueprint interface

[silent pilot]

I did cast to, but:

[obtuse herald]

inside your lobby pawn: GetGameMode -> Cast to (Your Game Mode) -> Get (Your widget variable)

[silent pilot]

MainSphere is the class of my pawn

[obtuse herald]

yes

also game mode is actually not a great place to create widgets

[trim matrix]

huh

[last abyss]

if your mainsphere bp inherits from pawn, it doesn't neccessarily inherit from character. so casting to character will always fail because the hierarchy for character is Object -> Actor -> Pawn -> Character

[obtuse herald]

game mode only exists on servers and widgets only exists on clients. It works for single player, but as soon as you do some multiplayer stuff it will break.

[trim matrix]

oh shit

ok so how can i start the widget then?

[silent pilot]

Yeah that makes sense, but how do I get some variables from the instance of the controlled sphere?

[obtuse herald]

Inside the player pawn works, or inside the hud class if you want to have your widgets contained in a separate class.

[random plaza]

how do you save and load ragdoll positions?

[trim matrix]

ah okay i will do that

[trim matrix]

why would it always fail?

[obtuse herald]

because GameMode is not related to Game_Character

[last abyss]

that really depends on how your code would be set up, if you're using an overlap (begin overlap / end overlap events) you get an 'other actor' pin which you would cast against a specific class. if that cast succeeds it gives you a reference to the actor and you can use that reference to get the variables you're looking for.
if you don't use an overlap, you'd likely use a linetrace that gives a 'hit result' and right clicking that pin would give u a 'other actor' pin. It also gives a lot more information, including if it actually hit something which is the 'return value' boolean on line/sphere/box trace nodes.
lastly, you can use get all actors of class, which allows you to specify a class and will return a reference to any instances in the world (granted that there are any in the world). however this shouldn't be used all the time, that's more for startup/initialization of levels.

[trim matrix]

Ah

[pseudo crystal]

Is there a persistent unique id for each actor that can be used to reference said actor later? I want to be able to export the unique ids of the actors in a level at any point (editor, packaging, runtime) and later get a reference to an actor from this unique id. GetObjectName doesn't seem to have a way to get a reference from the name, and does not seem to be persistent. My best guess is to make an editor utility that will assign a guid as a tag, then search by with GetAllActorsOfClassWithTag or saving a map of guid to reference. But it really seems like something that would already exist.

[trim matrix]

I dont know why but its more broken :)

wait

[obtuse herald]

GetName() is unique (per world) afaik

[silent pilot]

I just wanted to create a HUD that displays on screen the variables of my main class

[pseudo crystal]

Do you know if there is a function to get a reference given an object name?

[trim matrix]

Here i dont know why i cant press the buttons.
I Fixed the mouse in put btw

[last abyss]

and inside your widget you tried to use Get Player Character? because if the pawn you control inherits from Pawn, so if the Main Sphere bp's parent is Pawn, you should use Get Player Pawn.

[obtuse herald]

I don't think something like this exists. It would probably fuck up garbage collection as well, so be careful with whatever you are doing.

[silent pilot]

.... Im dumb

[obtuse herald]

that confuses me too :|

[pseudo crystal]

Hmm, good point, I should look into soft references for that

[last abyss]

https://tenor.com/view/spiderman-gif-24867002

[silent pilot]

Now I'd like to change the text (in a HUD context), the text is the variable here, however I can't seem to change it like I would change a string?

[obtuse herald]

try setting input mode to game and ui when start rotating too, but capture the cursor and hide it.

[trim matrix]

nope doesnt work either

[last abyss]

that's because what u have is a text object reference, you can put it in your graph and search for 'set text' when using it

[obtuse herald]

yes, with that I don't think you need the In Widget to Focus at all

oh wait

I should read

[thin cradle]

hey, is there a charactermovement event or something that triggers when the player leaves the ground, regardless of if it's by jumping or simply walking off an edge? I'd like to avoid just checking if the player's grounded every tick

[silent pilot]

oh, thx

[obtuse herald]

remove both Set Input Mode... nodes and see if you can click the buttons then

maybe something broke when we moved the widget elsewhere

[trim matrix]

nah i cant

wtf

[obtuse herald]

ok where and how are you creating the widget?

[trim matrix]

in the lobby_character

here is my movement stuff that i dont need xd

[obtuse herald]

set owning player to GetPlayerController

[thin cradle]

nvm found how to do it, on movement mode changed

[trim matrix]

the whole time i coudl walk the character lmao

[trim matrix]

doesnt make any difference

[obtuse herald]

also after adding it to viewport, SetInputModeGameAndUI

don't forget to set In Widget to Focus

[trim matrix]

ok ill try

nah

i think its not the problem with the input modes

[trim matrix]

it is...

[obtuse herald]

does it work now?

[trim matrix]

without the input stuff yeah

but with not

[silent pilot]

Thx it worked!

[obtuse herald]

Ok, other plan:
On Rotate:
GetPlayerController -> GetMousePosition -> (Save to variable)
GetPlayerController -> bShowMouseCursor = false

On Done:
GetPlayerController -> bShowMouseCursor = true
GetPlayerController -> SetMousePosition = (from variable)

[trim matrix]

you mean this?

[obtuse herald]

yeah

save x and y to a variable

[trim matrix]

vector 2d

[obtuse herald]

FVector2D should fit

[trim matrix]

yeah

im doing the mouse cursor btw on the bottom already

[obtuse herald]

that's fine I think

[trim matrix]

wait could it be the problem before

[obtuse herald]

Would be kinda weird but it could be

[trim matrix]

ok ready

[obtuse herald]

yeah that should do the trick ig

[trim matrix]

MOUSE LOCKED

xd

i could not move my mouse

[trim matrix]

i can only spin it in one direction

[obtuse herald]

oh wait, are you executing the nodes every tick?

[trim matrix]

yes

[obtuse herald]

I'm only realizing now

yeah

[trim matrix]

wait

uff

never mind

[trim matrix]

where else should i execute them

[obtuse herald]

there are key events

[runic urchin]

anyone have experience forcing LOD's via blueprint?

or have a tutorial that they could point me to

[obtuse herald]

these

ever used them before?

[trim matrix]

nah i never did

[obtuse herald]

you should

[trim matrix]

iknow

it would make so much more sense

the whole stuff

[lime moat]

anyone know if you can change constraints via BP?

[obtuse herald]

it's best so use them somewhere where input makes the most sense (Player Controller, Player Pawn)

[paper galleon]

You mean through code at runtime?

[trim matrix]

whats the name for it

[lime moat]

yes

[obtuse herald]

Key event (button here)

they don't exists in widgets tho

[trim matrix]

ye i put it in Lobby_Character

[paper galleon]

I think you need a physics constraint component to change that.

[trim matrix]

so then this sould work

[obtuse herald]

I think so

[obtuse herald]

what kind of component is that?

[lime moat]

I just added the physicsconstraint component, but it doesnt have any of the lock/rotation parameters

[obtuse herald]

You can also receive the mouse axis and rotate the pawn based on that.
https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/Input/ this is probably helpful for you then

[paper galleon]

Actually, scratch what I said. That's for joints between components

[trim matrix]

it Works.
I Will use that for my main game

[real notch]

Are there any options for blueprint/logic reviews? Like you walk through the logic of the game once it's finished and get feedback?

[zealous moth]

what was in the anim bp the node to set a rotation of a bone by alpha?

[stuck plaza]

Is it possible to pass a parameter to a level sequence event from a blueprint?

[lime moat]

Ok, any other ideas? :p

[paper galleon]

😅 not at the moment besides checking through the functions on the context menu for one that may do what you want.
I'm away from my pc else, I'd have helped.

[lime moat]

No worries! I appreciate the thoughts 🙂

[formal parcel]

how do I make a queue or stack in blueprints?

lifo or fifo is fine

[obtuse herald]

in what context?

[formal parcel]

like a stack/queue of ints...

its looking like that might be what a "set" is

[obtuse herald]

Do you want an array?

[formal parcel]

no

similar

stack or queue

lifo or fifo

[obtuse herald]

pretty sure an array is that what you are looking for

it's sorted and gets resized dynamically

[formal parcel]

no, not an array

[obtuse herald]

ok then what is the diffrence between a stack and an array

[formal parcel]

how long have you been programming?

[obtuse herald]

long enough that I am worried

[paper galleon]

Lol easy

[formal parcel]

if you've been programming a long time and dont know what a stack vs array is... i'm the one thats worried

[paper galleon]

Those are legitimate data structures

[formal parcel]

so anyways

i guess a set is effectively the blueprint stack/queue implementation?

it looks more like a map

without a value

[paper galleon]

There is in C++. I don't know if it's exposed to bp

[gentle urchin]

Its not in bp

[formal parcel]

damn

[gentle urchin]

But doing a custom one with an array takes like 2 sec

So idk what the fuzz is about

[formal parcel]

yea but performance impact is big

[gentle urchin]

Go cpp

If you worry about perf

[formal parcel]

yea i guess I can do that, been having fun with blueprints

[gentle urchin]

They're great

[formal parcel]

first thing i've ran across that i couldn't really solve with em

[gentle urchin]

For anything not done x1000000

[obtuse herald]

sounds like a limited array to me

[formal parcel]

toyB there are significant differences between an array and a stack and a queue, mostly in the way the data is stored and referenced, and also how it is accessed

[gentle urchin]

How big is your queue anyways

[formal parcel]

doing some 3d map gen stuff

[gentle urchin]

Ah

[formal parcel]

so... could be giant

[gentle urchin]

Gg then

[formal parcel]

making a flood fill algo

[gentle urchin]

Anything not cpp will be horrible

[formal parcel]

yea it feels bad already with small grids

[obtuse herald]

yeah I get that, but an array is the nearest you will get in bp

[formal parcel]

just doing basic stuff on a few iterations

[gentle urchin]

Yepp

[paper galleon]

Look for TQueue and TStack

In cpp

[gentle urchin]

Yeah the containers exist

[formal parcel]

i guess I'll just write the map gen code in c++ and keep the rest of the game in blueprints

honestly its easier anyways

[gentle urchin]

Thats the way to do it 😄

Combo

[formal parcel]

the lines are getting kinda nutty for basic grid navigation

[gentle urchin]

20% bp, 80% cpp

Or 90/10 :p

[formal parcel]

and i'm still unclear on like...

if i call a function and pull that pin to 3 places... does it do the function 3x or hold a variable behind the scenes for me?

[gentle urchin]

If its a 'pure' itll do it 3 times

If its not, the value is cached

[formal parcel]

makes sense

in normal programmer words, wtf is a pure function 🙂

[obtuse herald]

functions without an execution pin

usually green

[formal parcel]

ahh i see

so that will execute when "called"

[gentle urchin]

A function that "promises" not to modify the state of the actor

By the discresion of the programmer..

[obtuse herald]

'random integer from stream' likes to have a talk with you

[gentle urchin]

Yes, executes when 'pulled'by whatever is connected to it

[gentle urchin]

It doesnt modify the inputs

[formal parcel]

gotcha, thanks a lot for the help, kinda clears up the magic for me

[obtuse herald]

it does modifiy the stream

[formal parcel]

i ran into that bug yesterday oddly enough

[gentle urchin]

Rip

[formal parcel]

in fairness if it didn't it'd be basically useless

[gentle urchin]

So often it can be beneficial to keep a function "not pure" despite not modifying anything

[obtuse herald]

yeah but making it pure is kinda confusing

[formal parcel]

if it wasn't pure tho using it in blueprints would be a mess

[obtuse herald]

also true

[formal parcel]

imagine this without it being pure:

[trim matrix]

that looks cool

is it ue5?

[formal parcel]

yea

[trim matrix]

oh nice

looks like metro

the game

[formal parcel]

oh the lines

i use some paid plugin that changes em

[trim matrix]

oh bruh

[formal parcel]

stops the stuff running all across the way

[trim matrix]

whats the name of it

[gentle urchin]

Id stuff that in a new function

😄

[formal parcel]

pm'd ya

[wicked osprey]

Guys, why is my subject falling so slowly? I have enabled the Overlap collision for the item, but for some reason it does not fall quickly. But if you disable generate overlal events, then everything is normal. And I just need them☹️

[fallen glade]

I'm finding myself in a pickle, i'm trying to make certain actions (think sounds, camera shakes etc) fade from when distant from the center of the screen. I have it it set up and everything is working. Problem is that on the X axis things fade away much sooner than on the Y axis, not sure what I could do to make this feel more natural?

[fallen glade]

increase gravity>?

[gentle urchin]

Adjust it to aspect ratio?

[fallen glade]

How would you do that? @gentle urchin I thought about it but nothing comes up in my head

[wicked osprey]

And if I don't spawn the item in the character, then everything is fine

[gentle urchin]

Separate the axis, use different alpha ranges, add together and average ?

[fallen glade]

I'm not sure then sorry I haven't delved into physics much but there is a channel for it here #chaos-physics or #legacy-physics

[fallen glade]

That simple? I guess it is hah, thank you!

[gentle urchin]

Not sure it feels better, but worth trying ^^

Hmm

Add and average might be wrong

Multiply might be better ...

Id need to test some 😂

Brain doesnt work this late

[runic urchin]

How would you go about sorting and collecting static mesh actors under a specifically named Actor?

I am at a point where I can find the actor in the outliner via blueprint

[paper galleon]

Why not use components.

[runic urchin]

Kinda constricted to something that is completely proprietary

[paper galleon]

They're all in the editor?

[runic urchin]

yeah

So for instance I have an exterior and an interior group

I want to take and select all static meshes only in the exterior group

and sort those into an array

[paper galleon]

Well you need an array variable in the main actor.

[untold fossil]

Hello. Question. Working on a dynamic day and night system. How can I recapture the skylight without causing huge performance hits? Recapturing reflections tooltip reads: "This is very costly, will definitely cause a hitch"". What is then the proper way to update the skylight for a changing day and night system? Or is a day and night system without hitches not possible in Unreal (<- very had to believe that)

[proper dagger]

Hello! I know this sounds stupid, but how can I make an actor move forward backwards left right like a character if I don't have add movement input?

[paper galleon]

If you make the variable instance editable, add one array element and check if you can set that element to an actor from the editor.
I've never tried this so I don't know if it's possible

[spark steppe]

an NPC or an Player?

anyways, i think the character movement component gives the necessary functionality

[runic urchin]

I'll take a look at that

[proper dagger]

oh so I can just add that without making it a character?

[spark steppe]

i guess so, it's an actor component, so should work on every actor

[trim matrix]

Hi everyone! i'm stuck on this: i need to get the Sphere radius of each Static mesh, and get the value of the higher radius value... should i start like this?

[spark steppe]

if you want to find biggest one, yea

[proper dagger]

I can't add it, it's not in the list of available components

[paper galleon]

No it won't. It is specifically designed for a character

[spark steppe]

ok, sorry then

wasn't aware of that limitation

well yea, and if you inherit character it's probably already there

iirc character comes with the component by default

[paper galleon]

You have to manually code in the movement.

Basic lateral movement is
Location += velocity * delta_time

Do this in the tick function.

[spark steppe]

or interp move to component

[paper galleon]

Or this

But you have to set a location for that

I think they want input movement without a character

[proper dagger]

so I'd end up setting location every tick either way?

[proper dagger]

basicaly

[paper galleon]

Not sure how you want to pass in the input though

Since input is best for pawn and it's children

[spark steppe]

why do you not want to inherit character?

[proper dagger]

I have this submarine and the character interacts with the buttons

[trim matrix]

but whata should i add after the loop? how can i process all of them and browse to the biggest number?

[paper galleon]

Yeah, it's not very expensive dont worry.

[paper galleon]

Ah this. Okay. It's a vehicle

[proper dagger]

yeah but I can freely move around in it

[paper galleon]

Yeah, I get.

[spark steppe]

@trim matrix you make a variable, where you store the biggest one in and compare it to the one in the loop

and do an isvalid check on the variable, and if its not valid also overwrite the variable (which happens on the first iteration)

[paper galleon]

You can use a movement component. Maybe like flying movement component.
From what I can gather this is going to involve a bunch of complex movement that you'll need to code your own movement component in C++

[trim matrix]

awesome! trying!

[spark steppe]

so in pseudo code.... if(!isValid(biggest) || current.size > biggest.size) { biggest = current; }

[proper dagger]

at this point I feel like I should just convert it to a character

[spark steppe]

while you want a branch for the is valid check, and another branch for the size comparsion, otherwise it would throw an error either

[paper galleon]

Yeah.... You can but a sub is not a character.
When you mature more with the engine, you'll be able to program custom stuff

[gentle urchin]

Theres a function for a float array to get biggest value, which likely will be faster than a pure bp method, and possibly easier in general

[spark steppe]

also might be easier to setup and explain than my weird approach

[gentle urchin]

Not sure id call it weird but :p

[trim matrix]

Oh hi @gentle urchin !

[proper dagger]

thanks for the help!

[gentle urchin]

Hi :) So for each loop -> get bounds -> get the sphere radius -> add to a local float array
Then on loop complete grab the float array, get biggest value , grab the index, plug it into a get node for the original actor array, and return that ^^

[spark steppe]

wait, that returns the index?

[gentle urchin]

Horrible explanation

[spark steppe]

i was only aware of the one which sorts the array

i would go with a map

before he starts to call get all actors of class twice in the same method

[spark steppe]

iterate over the data, populate a map with the float as index and actor as value

grab the key array, and use that method above^^

and find the value

[gentle urchin]

Map is unreliable

[spark steppe]

how?

[gentle urchin]

Altho should be fine if you strictly only add

[spark steppe]

sure if two have exactly the same size it gets overriden

[gentle urchin]

And that

[trim matrix]

i don't get how you "add to float array" for each loop

[spark steppe]

what else?

[gentle urchin]

In a map the elements arent in a guaranteed order

[spark steppe]

drag the variable from the details to the bp graph, then you can select SET and GET, you want a get node

[gentle urchin]

Add 1,2,3
Remove 1
Add 4
Now the map consist of 4,2,3

[spark steppe]

but who cares?

you grab the largest key anyways later

[gentle urchin]

Nobody in this scenario

Two exact same size probably isnt an issue anyways.

Or idk. Not sure what the usecase is really 😅

Get all static mesh actors... hmm.

I guess thats one way of doing it

[trim matrix]

think i got it!

[zealous moth]

alright time for some math magic!
I got a ball with 2 bones: a root and a central bone.
when I press W or S, forward vector, I make the central bone rotate a certain amount on the X axis (since it is rotated towards the Y)
So far so good!

problem: when i move sideways using A or D, the rotation doesn't work nor follow.
When you press A and W, you get wonky rotations.

[spark steppe]

the result isn't predictable either with two same sized biggest ones

[gentle urchin]

Not make array

[spark steppe]

as even if you iterate over them, you have no idea what order the get all actors of class spits out next call

[gentle urchin]

I assume its the same order, every time

[spark steppe]

guess so, too. but you don't have much influence on it

[gentle urchin]

Given its the same set of actors

[spark steppe]

unless maybe one gets streamed out and streamed back in

[gentle urchin]

True

Risk involved

[trim matrix]

so how do you plug the radius into the SET array variable?

[spark steppe]

and somehow ends up later on the list, idk how unreal keeps track of those objects and where it pulls the data from

but i think, end of day it doesn't matter for that scenario 😄

[gentle urchin]

Get the float array variable -> add

[spark steppe]

don't use bones for that i guess? i think you make it unnecessary hard for yourself

[trim matrix]

working ! thank you @gentle urchin and @spark steppe !

[gentle urchin]

Sry for the typos, i suffer from saffs

[zealous moth]

not an option, it's the only way

[spark steppe]

well, then take the applied rotation into account

[gentle urchin]

First time i've heard something is the only way

[trim matrix]

one last question, is there an alternative for "Get all actor by class" but for component?

Get Component by class seems different

[gentle urchin]

Target actor, singular. Return value singular

Soo youd need to get the component in the get all actors loop

[paper galleon]

This returns the first component of that class.
There is the cpp version but I don't know if it's exposed to bp

[gentle urchin]

Check if its valid etc etc

Also first component sounds like it could go wrong

[zealous moth]

hahaha lemme explain
I tried using the ball method from the template, with the torque, absolute garbage in terms of reliability, physics and feel
it was way too unintuitive to tweak, so i threw it away
this method, uses normal movement component (since I don't want ball physics anyways) and just emulates the rotation.
The issue is the sideways rotation while following the direction of movement. If I press A or D, I expect it to rotate and start turning but instead it rotates all wonky

[paper galleon]

I mean cpp get components. The component version of the get all actors.

[fallen glade]

❤️ 🙏 @gentle urchin 🙏 ❤️ *it works

[gentle urchin]

So, looking forward, pressing A, the ball would roll leftwards?

[spark steppe]

guess at some point his yaw flips

[gentle urchin]

Damn yaw flips

You're prob right

[spark steppe]

how about a separate bone for Yaw? which doesn't inherit your forward rotation

[gentle urchin]

What about just faking it completely

With a material?

Surely no yaw flips there

[spark steppe]

you still have to move it somehow

unless the ball is a lie

[gentle urchin]

Its always a lie ;p

[zealous moth]

i tried the material route but that was too hard 😄

[paper galleon]

It seems like a complicated solution to a simple problem.

[gentle urchin]

True

[paper galleon]

If the skeleton serves no other purpose but for rotation, there are easier ways to rotate the ball

[zealous moth]

such as?

[paper galleon]

Add world rotation and the like.
You don't have to manipulate bones.

I don't know your exact set-up but you should try to reconsider your design

[zealous moth]

yup

best character

[trim matrix]

Does anyone see an error in here? I dont know why my widget doesnt want to close when i press the button i made

[paper galleon]

Wait...it is?

[zealous moth]

yep

[paper galleon]

I thought it was a prop or something.

[paper galleon]

Lol.

[zealous moth]

it's a morphball

[paper galleon]

Animation might be fine then.

[zealous moth]

considering it is tightly linked to input, yeah 😛

[spark steppe]

where is the escape button stuff hooked up to?

tick or what?

[trim matrix]

yes

[paper galleon]

But still I'm not a fan of animation for this stuff.
Looks like something normal code can do.

[trim matrix]

yes tick

[spark steppe]

and that blueprint graph is where? on the widget?

[trim matrix]

Yeah

[spark steppe]

is the settings menu relevant?

is that the main menu graph?

[trim matrix]

yeah pretty

[spark steppe]

so self is the correct target?

[trim matrix]

the setting widget gets called in the main menu

[spark steppe]

because you add the settings to the viewport

[trim matrix]

yeah

[spark steppe]

not to the main menu

[trim matrix]

yeah thats right

[spark steppe]

you only remove the main menu

not the settings menu

[trim matrix]

i dont want to remove it

just lay it over

[spark steppe]

huh

i'm talking about what happens when you press ESC

[warm lava]

Any clue why when I use "set material" I'm getting this:

[spark steppe]

esc removes ONLY the main menu with that code

[trim matrix]

it does perfectly everything

[spark steppe]

is that intended?

[trim matrix]

it removes the settings tab

i mean widget

[spark steppe]

i highly doubt that

if thats the main menu graph and you call remove from parent on self

[trim matrix]

yeah

[trim matrix]

thats escape key on keyboard

[faint pasture]

Working directly in rotations is all quaternions on the back end right?

As long as you aren't doing anything with axis values

[spark steppe]

but what's the actual problem then?

[warm lava]

nevermind setting mat to unlit fixed it

[trim matrix]

the button escape doesnt work

[spark steppe]

how did you close it the first times?

in the video^

[trim matrix]

through escape key on the keyboard

and that worked

[spark steppe]

dude

add an event to your button in the UMG designer

scroll through the details of the esc button to the bottom, on clicked event and add one

then hook that up to your remove from parent

[spark steppe]

the whole description sounded like the escape key on your keyboard wouldn't work (at least to me)

yea

so that was there before?

[trim matrix]

it doesnt work

[trim matrix]

nah

i added it

still

doesnt work

[spark steppe]

did you recompile that blueprint?

[trim matrix]

jeah

[spark steppe]

you added it like i told you?

[trim matrix]

yes

[spark steppe]

that should work tho

[spark steppe]

yea that looks fine

the button isn't disabled or anything?

[trim matrix]

nah it should not

[spark steppe]

i would delete it and make a new one

[trim matrix]

on the right it doesnt say anything with disabled

[trim matrix]

ok ill try

[spark steppe]

and add a new event then, the old one is probably screwed

[silk cosmos]

Put a print string on clicked and see if it prints

If not, then something is blocking your mouse press or your button isn't enabled

[trim matrix]

wtf

im confused

[spark steppe]

so am i

you probably added the mainscreen several times

click the button a few times

[trim matrix]

i did

[spark steppe]

a few hundred times

[silk cosmos]

How are you creating the widget can you show that?

[spark steppe]

if you do stuff on tick 😄

[paper galleon]

Remove from parent only works for panel widgets. You might have to wire back to the PC to remove from viewport

[spark steppe]

no, it works fine when he presses ESC key on keyboard

[spark steppe]

but that would also work fine with a ton of widgets

[trim matrix]

thats where i call the widget

and its in a character

thats my character

[paper galleon]

Oh? Strange

[spark steppe]

so the screen that you showed is the lobby widget?

your main menu

[trim matrix]

yeah

[spark steppe]

can you add a print string at the method which works for the keyboard key?

and see how often it prints once you press esc to close the widget

should only print once

[trim matrix]

ignore last 5 seconda

seconds

me beiing dumb

[trim matrix]

HOLY

one escape keypress on keyboard

[silk cosmos]

On clicked for the button use a print string and plug in self to the target. Idk why it isn't working

[trim matrix]

@gentle urchin working great!! thank you!

[spark steppe]

because that still looks like the widget exists more than once

[silk cosmos]

That would be my guess but it's only created on begin play

[trim matrix]

okay imma get off now its 11pm

gn

[spark steppe]

move that create widget stuff to your begin play of the level blueprint or something

just to test if thats the issue

but most likely it is

[trim matrix]

its shit

bc then i loose a function of the lobby

[warm lava]

need to store multiple objects and their assigned materials together in some sort of array/variable to return them to their state after doing some work... anyone point me in the right direction (node)?

[spark steppe]

no you dont

you have to refactor it tho

[trim matrix]

im gonna do it tomorrow

thanks anyways i will come back tomorrow

[whole mural]

hi all, i'm currently trying to learn to code (im an artist) and im having an issue with my AI and i would love some help. My enemies spawn through spawner blueprints (not target points) and i was wondering how i would go about getting them to run towards a target point (in this case my base). The only way i have found is if the enemies have been placed in the world, i can then assign the target point to run to, but because my code spawns them on a delay, they are not in the world, so i want to predetermine the target point before hand.

[spark steppe]

sounds like a threat 😄

[spark steppe]

can't they figure out the target on their own once they got spawned?

you would make an AI task which gets the target location, and updates the blackboard value

that way they would/could also follow moving targets

[whole mural]

forgive me, but i have no idea what that means 😂 i have been learning blueprint just over a week

[spark steppe]

do you even use a behavior tree at the moment?

[whole mural]

no sir

[spark steppe]

well, you most likely should

spent a few days to learn about them, they gonna save you a bunch of time and headaches

[whole mural]

okay, i'll look into them, thankyou

[spark steppe]

as a starting point, you could look into tutorials like "how to make ai follow character"

even if you have a static target, the workflow is kinda the same (just that you don't have to update the target periodically for a static goal)

[trim matrix]

Btw i maybe should check if the widget is valid or not and then make one when it not exist

[spark steppe]

that could work, too

[trim matrix]

Bc if i press escape it spams the console

I mean print

Ill try it tomorro

[spark steppe]

try it now, pretty sure it might work

then get resting sleep 😄

[trim matrix]

Nothing is working

[thin panther]

gonna have to give a litttle more info than that

[silk cosmos]

That's asking for too much

[spark steppe]

i still can relate to it

[trim matrix]

lol

[trim matrix]

Im already in bed

[warm lava]

I'm changing objects materials at runtime, any ideas how I can change them back to default?

[trim matrix]

Best things comes in mind when ur right before sleep. I really need to get a paper and write that down xd

[spark steppe]

save a SOFT reference to the original before you swap them

or try to get the material from the static mesh, maybe that returns the default

[warm lava]

thank you

[spark steppe]

i would try the later first

as it's likely that the override gets only stored on the static mesh component, not on the static mesh

and report back please

as i want to know now, too 😄

[warm lava]

thanks! will let you know where i land

[glass stump]

why doesn't 'event begin play' - > 'world camera shake' work?

[silk cosmos]

Can you show the camera shake node?

[onyx token]

i wanna check

if my animation

is a block animation

is this node really expensive?

[glass stump]

It works when it's 'box begin overlap' but not 'event begin play' for some reason.

[silk cosmos]

Might need a slight delay before it gets called. Not sure

[mellow folio]

What actor is this on

[glass stump]

Whoa, that worked. I thought I tried that already but I just tried it again now and it worked this time, although the shake was way subtler than it usually is.

But thank you, it works. :)

[warm lava]

probably doing something wrong but seems changing runtime it loses the original

[spark steppe]

if you use a soft reference you have to load it back to memory if you want to change it back

did you do that?

[faint pasture]

#gameplay-ability-system

[raw orbit]

anyone got a nifty method to rearrange an array of integers so that lower numbers come first and higher numbers come last? i hope im explaining this right.

For example if i have an array of 9,7,8 I'd want it to be 7,8,9... at index 0,1,2 accordingly

maybe theres some node i dont know that can help with this

[runic parrot]

Hi! one question, how would you go about creating a 2D matrix of X,Y that references to one Object Each?
So that you can access each Object with the coords (X,Y).

I'm just adding this objects to one array and than using the H/W of the (X,Y) cords to calculate what should be the position on the array, but there has to be a better way

[west gyro]

any ideas why my montage gothit is still getting triggered even if the first branch is true and death condition is true?
i can hit the target till the delay is over and the actor is destroyed

[wicked osprey]

Guys, which solution is more correct. I need to bind the dispatcher of one component in another component and they all belong to my Player. Which method is better in your opinion. To bind the dispatcher inside the second inventory or to bind it inside the character.

[pine trellis]

what is the correct way to get a command line into the engine to load a map? I am using -Level=Mobile2 -Mode=FFA -ServerName=PORT_KNOX_SERVER
but its not working on my dedicated server is there some other kind of way to load the map? I tried this code everywhere it could work but it only returns the name of the server

[spark steppe]

i would do it on whatever implements the event

[runic parrot]

Is there any way to edit a DataTable on Runtime? If not, what structure would you use to get some functionality like that?
I want a list of things that i can edit at runtime and that they remain after leaving

[zealous cedar]

Hi all, why is the Hidden Actors array not available in a SceneCaptureComponent2D?

[faint pasture]

Dense or sparse?

[faint pasture]

No but as a workaround you can use a save game

Write savegame at runtime, copy it to data table at editor time with a utility

[faint pasture]

Your options are to make a function library to convert to/from XY to index, or use a map of integer vectors to objects if you want the data to be sparse. I'd use a map for a grid system unless you need the grid to be mostly full

[runic parrot]

Dense, i guess i'll just use the function to get the Index From a set of cords.

[runic parrot]

Ty, i was getting some troubles with this one.
If i got the idea right, it should be to Generate a saveFile while at runtime and than use some widget utility at the editor to Update the DataTable, correct?.

the EditorUtilityBluePrints should do the work, i can see some cvs/json files to update the datatables, ty!

[faint pasture]

That's how we do our 2d tilemap stuff.
i = x + y * width
x = i%width
y = i/width

Might have an off by one or two in there but that's the idea

[meager latch]

Urgent!!🔥 Can anyone point me in the right direction to build a landscape interaction system that will allow for a plots of land system. For example your in game and you purchase a chunk of land on the landscape system. My question is then how do i get that chunk of landscape land to highlight and well get the player to be able to purchase it, any ideas welcomed pls.

i found something with tracing but that requires a volume

[runic parrot]

For the highlight something like this should work

https://www.youtube.com/watch?v=KakLXqpwnjo&t=1s

[meager latch]

will watch

i suppose that helps but i want to interact with the landscape if i could just figure out how to make one square of landscape and interact with it

[runic parrot]

As for the user buying it, if you don't have a collision on your plot of land, you can have an array of cords that point to info of each plot of land, when you go into buymode, you Snap the position under cursor and get a (X,Y) from there and retrieve the plot info with that.

[spark steppe]

how is this more urgent than any other question here?

[runic parrot]

Maybe be wonky if your plots are not all the same shape

[meager latch]

lol i work in sales so we do that in order to get attention try it dont be mad

[meager latch]

this is good

[runic parrot]

https://www.youtube.com/watch?v=DwPHsLJv5Gw

[meager latch]

i like that this can help for sure

[spark steppe]

i rather dont, and neither should you

[meager latch]

this isnt a crazy question but i just need to be pointed n

[runic parrot]

i did exactly what you are asking for the other day, but i'm not sure how are you going to do your plots of lands

[meager latch]

nice, not sure either im thinking a spline system to contain it

if they are wonky shapes then i just need to have one point to reference to its middle point

really appreciate this

[meager latch]

sometimes just talking it out helps

nice

its not the same shape for sure

[runic parrot]

Maybe just let the land be as it is and don't worry about it.
When going into Purchase Mode, you can have a set of collision boxes (or other shapes) with different extens. You place them all on the map when going into purchase mode and you check collision under cursor to "select" one.

[meager latch]

thats alot more simple

that will do really

I do want to build a mini map that can see what land is bought too

but i like these apporaches

thanks dont want to drown out anyone will look into this thanks again @runic parrot

[solemn crescent]

I have a pawn with two variables.
How do I set them from the scene.

I need to control and cam and plane in the scene.

[runic parrot]

Not exactly sure what you are trying to do, but changing the default values of the variables should probably do it.
Make sure the variables are set to "Instance Editable" if you want to change them for each one

[solemn crescent]

I want to alter the Plane position with the camera direction when I press a key. I’ll try instance vars

Very new so I’m struggling along… likely doing things wrong.

[runic parrot]

hmm maybe go into your controller and check for the input you want "INPUT x Key" (you can customise input types on the editor if you don't want to use default keys).
Trigger one event or method when the input is received and there, check the camera position or whatever you want to do and do it there.

[solemn crescent]

That’s way over my head.

I made a pawn to collect the key event with variables connecting to the cam and plane in the level.

Ideally the cam/plane could live across levels.

Is what you’re describing related to game gameplay settings?

[runic parrot]

You can check for input on other blueprints that are not the controller, but you need to enable the option to receive input first.

I have no idea now what you are trying to achieve

[solemn crescent]

Essentially this

I make this test in the level_bp, but I’m having trouble translating it to something portable.

It just repositions a textured card in front of the camera.
Another key should cycle the texture.

[sage shale]

Aw 😦 well no I didn't mean dispatchers in specific, moreso mid level topics like mmm I know the blueprint essentials like hey this is how you set a variable but I don't understand things like cast to or dispatchers or custom events in Unreal really. and ofc that's just the examples I know not the ones I don't so I'm not really like sure what all I should try and learn? I'm not trying to learn EVERYTHING because I know that's too much but I wanna learn all of the useful things.

or rather as much as i can*

[quasi folio]

Is there a way to create a "wait until" style function? I know while loops exist but they very easily crash.

[sage shale]

delay?

[quasi folio]

if you will, basically wait until x is true..

[sage shale]

no no I mean there's a delay function is all but I don't think that's what you want- I'm pretty sure that's time based

[quasi folio]

it is time based unfortunately, yes

[sage shale]

what is the specific example you're trying to do?

[quasi folio]

heres what I'm attempting to do, I have an animation system, when one finishes I want to immediately execute another action, and I have a bool set up for that, just need the code to wait until that bool is true to perform next action

I hate the AI blueprint so, I'm not doing that rn. Experimenting a bit.

[zealous cedar]

Can anyone help me with this? I’m sure it’s very simple 😸 - can you add Hidden Actors in the Construction Script perhaps?

[sage shale]

errrrr is it super time sensetive or could you make a loop that checks it every .1 seconds? not exactly a while but I think it should be more resource intensive than one

[quasi folio]

If the macros themselves allowed that, it'd work.

[solemn crescent]

I staged it in pawn, but it doesn’t seem to be working.

How do you create the Do Something nodes?

[sage shale]

wdym the macros? as in the bps?

[quasi folio]

@sage shale While Loop is a macro, which you can edit.

hold on

[sage shale]

welll it's not impossible for you to edit the code n make it allow it I don't think-

Either way, why don't you get the time of the animation and add a delay inbetween it and at the end of the delay it would trigger the action?

[quasi folio]

got it working.

[sage shale]

AYEEE nice, how'd ya do it?

[quasi folio]

Basically the way you said, hold on

[sage shale]

hah sweet :DDD

[quasi folio]

Not pretty but it works.

[sage shale]

I'm not the best with bps but I'm decent with the logic... I think- 😎

[sage shale]

oh but Darky is there any chance you have any ideas? alskdjalksd

[quasi folio]

Ah, right, let me review and I'll give it a go.

[sage shale]

Okayyyyy thank youuuuu :)))

[quasi folio]

@sage shale Cast to is a bit of a nightmare but I can try to explain. Custom events aren't too hard. Heres the thing. I've got a 7 hour meeting today, and its already 1am. I need to sleep. But I'll add you to my DMs

[sage shale]

alright! 😄

[golden frigate]

not sure y but i attached some pawns to my player's hand and now when he walks it goes really insane

[tawdry surge]

Casting is just changing the reference type to access the data of a lower class.
All actors have a location. Not all actors have the variables/functions/events that characters do.
So if I have an actor type reference to the player and I want it's speed, I'll need to cast to(change my actor type reference to)the player class type

[golden frigate]

ive tried debugging y it happens in places that r probably but have had no effect

it isnt my custom camera code, it isnt my setting the rotation of the 3rd person model to absolute

and the WASD values r the same

i just did this to spawn some key actors and attach them to a socket on my hand

if i disable this branch it doesnt bug out

maybe i need snap to target? ill try

nope

[onyx token]

is there a way to do this?

this is an infinite loop

but i want to press the right mouse button - which is 1 event-

and while i press it, i want to check every frame if the bool is suddenly true

like as long as i'm pressing RMB, i want to continously check if the bool is finally true so i can move on with 1 signal

well-

turns out i can do ugly stuff

and do this

which makes me feel filthy, but it works.

[thin panther]

Can you not just set the bool on event tick or smthn

Or check the bool on event tixk

[onyx token]

i guess i could make a new bool that says "right mouse button pressed"

and put that one on event tick

but that'd be even uglier

[golden frigate]

any reason attaching a generic actor to a player BP (player is parent) would make ur wasd input wonky?

[icy dragon]

What are you trying to achieve?

[runic parrot]

Hi! does anyone know if there's a way to get all "Child classes" of a Main class? i want the references so i can spawn one of each.
For example: All Child actor classes of the lass below (the class reference, not the ones spawned in runtime)

without using a DT, i can use a DT but i'm trying to get a more dynamic way of doing it

[willow gate]

Hey folks. Any idea why I'd be getting the error: "Failed to resolve the table input. Be sure the DataTable is valid." ?

The Item Data Table / Item Row Name is a public, spawn exposed Table Row Handle structure which has valid values assigned in the object that are causing the error.

[willow gate]

Tried this?

[runic parrot]

Works for the ones that are spawned already at runtime, not for the class references on editor.

[upbeat inlet]

has anybody found good tutorials for an inventory system I've tried one and failed as there was way to much detail and the dude kept doing stuff without explaining what he did properly.

[willow gate]

Ryan Laley does a great series

[runic parrot]

was about to recommend the same one, it's really simple

[willow gate]

He's updating to UE5 video by video as well currently

[willow gate]

Hmmm... wait so, where are you trying to spawn these at? Do you have an actor that is doing this?

[upbeat inlet]

I want to wait for a UE5 version as I don't want to get stuck mid code walkthrough. it gets me lost quick as I started with blueprints and have not practiced C++ much

[willow gate]

Oh, these are BP tutorials, not C++

[upbeat inlet]

I badly wanted a Tarkov style inventory, and was fallowing this guy. but it was super frustrating as he kept doing things without explaining properly. had to scrap my code because I was stuck with no lead as to where to start debugging. https://www.youtube.com/watch?v=4CjpBoKl6s8&ab_channel=ReidsChannel

[runic parrot]

At Runtime i want to gather a list of all the class childs (not the one spawned, but the one availables) of X class.
the spawn of actors of those classes is secondary, with the list of child classes i'm ok

i'm already doing a DT, i'm so freaking lazy

[fading oyster]

Sorry to interrupt rq, but I had a question bout some maths

[willow gate]

Ah, well the one I recommended won't help much I don't think since it's individual slot based rather than multi-slot/size based m8.

[fading oyster]

I am making a machine gun, and the longer its shot within like 6 round intervals its firerate is supposed to decrease to a minimum value.

The variables I am working are,
Firerate Default
Firerate Current
Firerate Minimum

I would need to decrease the current firerate to the minimum within the lenght of shot intervals which is 6 atm. Does anyone know the math behind this, I would love it if you can also explain it thanks.

[runic parrot]

A grid inventory system is a little bit more complex i think, i would go first with creating the most simple inventory type and later expand when you have an idea of how they work. they are all amost pretty much the same.

[willow gate]

hmmm.. and what's the desired end result? It might help to find a solution if we know what you're trying to accomplish.

[fading oyster]

Yeah, grid is basically a normal inventory but with more on top

It gets really complex rq tho

So I would definitely suggest learning how to do normal slot inventory before moving on to grids, because you also need to know a lot more about widgets and all that too.

[fading oyster]

But rn my brain literally cant comprehend how I can do this lmao

[willow gate]

Lemme whip up a quick BP setup to see if it's going in the direction you're trying to go.

[fading oyster]

Thanks dude I appreciate that

Also here is my math, obviously since everything can change nothing is static the example I gave is just to be able to understand the equation

This is the calculation of the "Interval" or just shot num that I use to loop the firerate with

The lenght of fire anims is 6 atm, its 0-5 but reads as 6 just like the example

[runic parrot]

Short version: Replicate this functionality

[willow gate]

https://blueprintue.com/blueprint/bpx-3knx/

Try something like that. And sorry I was working on this before I saw your image post lol

[runic parrot]

Long version: I'm doing a Procedurally generated Tile Map with "wave function collapse" algorithm.
One of the steps is to get all the Tile classes and map how they match with other tiles on each direction.
My pipeline is to spawn them all into the world and keep the process going.
I want to make it so the process can just pick what ever is on that folder and update them all o just pick all the "childs" of P_base (my father class)

[willow gate]

Oh man. I'm not sure this is within my ability to help with. Hopefully someone smarter will reply.

[runic parrot]

No problem, i already got most of it running, i'm trying to optimise that part because i'm lazy af

[fading oyster]

All good dude 👍

But yeah, basically the thought is how it gets divided eventually into it, it shouldn't get set to it immediately

Also the shot count can be whatever it needs to be just need to find a way on how to divide it per that value

[willow gate]

Ahhhh ok so... is this happening inside of a function or on your event graph directly?

[fading oyster]

I don't know I was able to explain it right 😄

[fading oyster]

Anywhere is fine, its just the math equation that I need to calculate

[willow gate]

You familiar with lerp?

[fading oyster]

Ye

[willow gate]

Why don't you lerp between the values and use a timeline or a timer (if you wanted to avoid timelines) as the alpha?

[supple needle]

Hi all, I'm very new to unreal but trying to learn through tutorials but stuck trying to figure something out, might not be using the right lingo

I would like to use a midi device to manipulate a variable in another actor, but cannot figure out how to get that and then manipulate

[fading oyster]

There was a speicfic node that I forgot the name of

Which would solve this issue I think fuck 😂

[supple needle]

I tried this at first but its returning a value of none

[fading oyster]

How are you getting the actor?

[willow gate]

hmmm

[supple needle]

is this the incorrect way to get the actor?

[fading oyster]

"MapRangeClamped"

I think that is what Im looking for

[fading oyster]

What is setting the variable?

[supple needle]

setting it up to have midi input set it

the midi input works but i cannot figure out how to control the "vertical rotation" value under default for the other actor

I have a midi control actor trying to manipulate a light actor

[rich jungle]

is there any way to set calls like "get player state" to return my custom player state instead of the generic one?

(kind of assuming no but doesn't hurt to ask because it drives me crazy constantly casting)

[supple needle]

i might have figured it out

nope

lol

have an idea though...

ok i figured it out kinda...

but its rotating the entire object instead of parts of it so i need to dive into the next depths i guess

[fading oyster]

It should be

As you are using "SetActorRotation"

if you only want to rotate a component of it use "SetComponentRotation"

[fading oyster]

No you can prob make a function libary pure function tho

[supple needle]

o ic, let me look at that

[supple needle]

Thank you this is what i was looking for

[fading oyster]

No worries 👍

[solemn crescent]

Setup a Pawn with variables connecting to a CineCam and Plane.

I’m able to connect the variables if I drop the pawn in the scene, but if I set the bp class as the game mode default player.

How can I wire this up?

[leaden dock]

i have a dataasset behaving weird, it matches names to meshes. i passed a reference to it to my thread, then it crashed when i exited the game, dunno why.
ever since then it matches wrong meshes for names.

actually i didnt write to it or anything, only read from it

any idea?

[leaden dock]

ah i messed something up in the code, it works fine 😛

[frozen ledge]

i've been looking at a bunch of different examples online and I can't seem to find out how to bind an event with x amount of parameters, if anyone can help that would be great

I know how to broadcast an event with parameters but I should be able to bind

[tawdry surge]

You mean an event dispatcher?

[frozen ledge]

I think so, yeah, I'm pretty sure those are separate from events though

DECLARE_EVENT_OneParam(ThisClass, FUpdateProperties, TArray<AMapBuilderActor*> Actors);```

this is how i'm declaring it

I'm pretty sure this isn't an event dispatcher but just an event

[runic parrot]

Hi! does anyone know if it's possible to merge all the meshes from multiple actors into the mesh of 1 actor and remove all the others? This at RunTime.

for example, each one of this tiles has one actor and multiple meshes, can i merge all of them into Only 1 mesh and One actor, for performance?

[barren flower]

https://docs.unrealengine.com/4.27/en-US/Basics/Actors/Merging/#:~:text=From the main menu choose,for merging the selected Actors.&text=Click the Merge Actors button,a name%2C then click Save.

Has anyone here done any procedural cave stuff? What would be the best approach? Splines maybe? But how do I merge them if you have intersections?

[runic parrot]

I was watching a sht ton of procedural algos yesterday, the best one for caves so far is this one

https://www.youtube.com/watch?v=v7yyZZjF1z4&list=PLFt_AvWsXl0eZgMK_DT5_biRkWXftAOf9

[barren flower]

A yup, Sebastian is always a winner. The generation is fine but how would you render this is my question

I feel like marching squares isnt going to be performant in game(and also I dont know how to do it in blueprints ahha)

[runic parrot]

hmm i got some not so bad results when playing with celular automata, let me get a picture

[gaunt steeple]

Hi.
Buttons 1, 2, 3, 4 are from another Blueprint, but in this Blueprint, I would like to reference some Options that I have already programmed, so, I use Cast To Widget to reference my variables in a new Blueprint. It doesn't work for the FadeIn variable and for ON Clicked (Button 1, 2, 3, 4).
Is my way of doing it correct? If not, I would like to know how and also how I can do it for the other Nodes. Thank you.

[runic parrot]

This is 10k Tiles with 1 simple mesh Each

i can bump it up to 200x200 and it takes 5 secs to generate the map, apply the regules and clean the borders.

and the logic is really really bad, it can be optimized a lot.

maybe you can use something like this and extrude the borders to make cave walls

than follow like sebastian, separate regions by flood algorithm and cave path with A* or sjk

I think POE is 30x30 tiles or something like that, just to have a reference

[runic parrot]

This doesn't work, it needs to be at runtime. But it can be achieved with procedural meshes, it's kinda similar. The link got me there, so thanks : P

[hexed barn]

Hi, I have made a bp with a paper tile map and some box collision but each time I relaunch my editor they disappear

and my question , because my message just like that is not really well written, is : why does the bp keep disappearing (placed in the editor) all the time? like I still have it in my folder but for it to spawn again I need to replace all of these bp

[runic parrot]

Are you placing it before starting to run the game or while running it?

[hexed barn]

well I place it then play it work great, then I restart my editor all bp placed (of this type) are not visible, they still there but no more collision, I can only see the collision box in editor mode

[runic parrot]

Maybe you don't have enabled the collision boxes

[hexed barn]

it don't change anything, let me get some screenshot because my explanation is not really great

so this is my bp (I just placed it)

and this is after a restart

and my character can't go on anymore

just like the paper tile map disappeared

[runic parrot]

what do you mean by a "restart"?

[hexed barn]

well I closed my editor then launched it again

[runic parrot]

if you are saving, everything should still be there, it has to be something on your bp logic i think

[hexed barn]

like when I stop for the day and open the project again tomorrow

I do save everything

[runic parrot]

maybe some corrupted asset reference?

[hexed barn]

the bp in the assets still work if I place it the bp will spawn normally

I remade the same bp a second time

same problem

I will surely find another way to do the bp and it will work, for now it might be 7:12 am and I am not someone that wake up early 😅

[runic parrot]

Does anyone know if you can move one SaveGame Slot from one project to another? Given that both have the same format

[final lava]

Probably stupid question 😅 How to use enhanced input plugin for multiple button input? For example: I want to know if person did pressed two keys at same time?

[drowsy veldt]

What is the point of Events in Unreal as opposed to functions?
Trying to search for the answers yields the basic differences (events can't return values, but can use the delay node etc etc), but it doesn't explain why events are a thing.
What problem they exist to solve?

There's a usecase why events had to be invented and should be used for, and I can't find what it is.

[runic parrot]

events are async, methods are sync

So with events you can run one event and trigger delays and things related to time.
With methods, you are blocked until the method is done.

[runic parrot]

I already closed ue5, but i think on settings -> Input, you can enable input with multiple keys

[drowsy veldt]

But wouldn't you encounter all sorts of multi-threading madness if events would run off the main thread?

[runic parrot]

That's my understanding of it, i may be missing a lot of things that may be important

[drowsy veldt]

I might be misremembering things, but I remember making an incredibly slow block of code that was called from an event hanging the main thread

[runic parrot]

https://pixelsapiens.com/functions-vs-events-in-unreal-engine-4/

yeah, that's pretty much it.
Functions are sync and blocking, Events async.
Also local variables on methods because of the blocking nature of it

[runic parrot]

That something is Async doesn't mean it can't slow down the main thread, if it's eating all the resources, there will be nothing left for the other threads.

[drowsy veldt]

There's one explanation I'll try to test: it's async, but it's still on the main thread.

[runic parrot]

it's like a bully standing in front of someone taking all the walkway and saying "yo... i'm not stoping you. You can go whenever you want"
