blueprint

[timid yarrow]

How?

i used hit location for sound that i play

[thin panther]

get the angle between your up vector and the hit normal

[timid yarrow]

ok i'll try thank you

[lofty rapids]

it's nice to have the widgets in the HUD, but you can code it anyway you like, i just don't understand what the code is doing, recreating a widget that's already made ?

[wispy badger]

Lets go back to the beginning.
When you start a game, you have a main menu with mostly 3 buttons: Start game, Options and Exit

That panel is a separate gui. Options button leads to another separate gui with game options (They dont need to be saved anywhere else. Just save them in the current session.).

When you click the Options button, a new GUI should appear. Main menu should hide. Both need to exist only once (only one instance of a class is allowed)

[lofty rapids]

ig i'm wondering why you don't just hide/show them

you are creating every time you display ?

[wispy badger]

because one cannot access the other without having references to each other

[lofty rapids]

hmm

[main lake]

For that, you should use a "Widget Switcher" : https://youtu.be/7Mbe-hQl0Yg

[wispy badger]

Thats not really the effect I want

I dont want to put them in a separate container

[lofty rapids]

you really don't want to be creating the widget over and over

[wispy badger]

I just want to get reference's class. Thats all

[lofty rapids]

ig you can

[wispy badger]

Yes I know that

[lofty rapids]

it's going to be a bit difficult from one widget get a reference to the other

that's why i put it in the HUD

i just throw the widgets in the HUD, and switch them around

[wispy badger]

HUD is something completely different

HUD is not capable of holding main menus

HUD is something a player can see in the corner of the screen

[lofty rapids]

Heads Up Display

i use it for all the widgets i use

so i can access them easily

[sonic crest]

Isn't that supposed to be a Heads up Display? I use it for any widget

And all works

[lofty rapids]

if your main menu is just a widget

[wispy badger]

HUD is only good at handling guis at the side, because thats its purpose, HUD is not a main gui

[lofty rapids]

Just stuff your widgets in the the HUD

you'll have a lot easier time accessing them

[wispy badger]

no I wont

Going back, can I get a type of a reference that is empty?

the underlying type of a reference

[sonic crest]

Make them all in the same widget?

[timid yarrow]

thank you a lot! it worked!

[wispy badger]

that would be even worse

[sonic crest]

I know

[gentle urchin]

So strength(assuming there is one?) would increase the distance between the points, and the points would have some semi-static value/calculation for their .... erh forgot what their called

[sonic crest]

I actually did it before with the back function, going back to the actual previous widget, not having them all in one widget, but I totally forgot how

Spent a year looking for that old project and I failed

[gentle urchin]

What a wasted year 😅

[sonic crest]

Ha.

Just a year ?

😂

[lofty rapids]

for my main menu i just possess a main menu pawn, and show a widget

[gentle urchin]

You bothered making a pawn for it 🤪

[sonic crest]

Why

[lofty rapids]

It works like a charm, i don't need to use another level

[lofty rapids]

because i like to party

[gentle urchin]

But that means you load the main level during main menu

Gotta be somewhat slow ?

[lofty rapids]

i don't load anything during main menu, the level is procedural generated

theres almost nothing in the editor

just the main menu stuff

[wispy badger]

So, without a separate variable holding the class its impossible?

[frosty heron]

@wispy badger Of course a HUD can contain any widget including your main menu. It's just an object where you can throw stuff

you can easily create a main menu HUD and throw your main menu widget there and assign main menu hud in your main menu level

[sonic crest]

^

[frosty heron]

saying HUD is a thingy that show in the corner, I don't even know where to begin with this assumption

[wispy badger]

the concept of hud doesnt extend to the main menu but whatever.

anyway could we go back to the original question, please?

[frosty heron]

@sonic crest I don't see anything wrong with having everything in one widget, infact I do that all the time

having a master widget makes it easy to control childrens

many times my children have to communicate to each other and the values cna't be stored in children but in parents, because the base class is accessiable by all children

[sonic crest]

I just don't like it much. I did it before tho

[frosty heron]

Yes it does? wut

in what why that it doesn';t facilitate main menu

[wispy badger]

this basically ruins the concept of main menu inside a hud

[frosty heron]

What's the question anyway, you want an object reference to return a class when it's empty? I mean do you expect the engine to conjure something for you.
If you getting an object that's empty you are not gonna get any class

[gentle urchin]

Ah right. Well then its a different story ofc.

[lofty rapids]

the HUD is a place you can put your widgets tho, so it works well. I don't see how i would access one from the other without it

[wispy badger]

If you getting an object that's empty you are not gonna get any class
But the variable still expects some type. Its not lua where you can feed anything to it, right?

[sonic crest]

Well. It's a HUD that displays custom widgets that can be interacted with. You're not technically interacting with the HUD. Just the widgets

[frosty heron]

What do you even google, we are talking about Unreal HUD.
Hud is just an object that is tied to the level settings. It's something created when you run the level, you can put anything.
HUD is the object, you interact with the widget

You create widget in the hud, it can be anything including your main menu

[wispy badger]

lets just forget about the hud for a moment

[lofty rapids]

I mean how would you reference one widget from the other to hide/show ?

without putting it somewhere you can access

[sonic crest]

What was the question tho??

[frosty heron]

I put all the widget together (Master, main menu, option, setting, etc)

just show and hide as neccessary

[lofty rapids]

^

[lofty rapids]

so it's one widget ?

[frosty heron]

an empty ref will return empty class

[frosty heron]

Yup

seen some people destroying widget to open another widget

[wispy badger]

shouldnt it store the type it expects somewhere?

[frosty heron]

I think that's atrocious but I could be wrong

[frosty heron]

what type?

it's just null ptr

[wispy badger]

its not a pointer but reference. A little difference

[frosty heron]

An object ref is a pointer

[wispy badger]

the object's type (a class)

[sonic crest]

You can store it in the HUD to access it later

[frosty heron]

A class reference is not an object ref

your blue pin is a pointer to an object

[wispy badger]

I know

[lofty rapids]

so you probably want another variable

[wispy badger]

It still expects specified type. You cannot pass an integer to an object that expects a blueprint class

[lofty rapids]

that holds the class

[frosty heron]

What are you doing with your main menu anyway

[wispy badger]

everything a main menu needs to do

[frosty heron]

like?

[wispy badger]

like starting the game, existing the game and setting game options

[frosty heron]

k so what part are you struggling with

why not just drop them all in one widget

[wispy badger]

because it would be chaos

a shit to debug

[frosty heron]

it would be easier to debug

[wispy badger]

no it wouldnt

[frosty heron]

you handled all the flow from the master widget

well you do you I guess

[wispy badger]

Can we go back to the main question?

[lofty rapids]

I still not sure what your doing, trying to recreate the widget again ?

[frosty heron]

doing main menu is probably one of the easiest task for me

[wispy badger]

instead of splitting to unrelated things

[wispy badger]

no

[lofty rapids]

so your probably need another variable for the class

[wispy badger]

I want to get the object reference's type to pass it to Create Widget so it would construct the widget first

[sonic crest]

When you hit back, you save the previous widget somewhere to open it again?

[wispy badger]

in the core of unreal it doesnt matter if its a pointer or a reference. It still holds the type

[wispy badger]

I want to have it in a variable so I can show it in a viewport again, yes

[lofty rapids]

Sometimes the main menu is a whole other level

I seen some videos on it

[wispy badger]

it is in my case assuming main menu widget + options widget in the same level still applies in that definition

[lofty rapids]

i like the "widget switching" idea i didn't know that was a thing

might be good for your options

[wispy badger]

its not good for my purpose

[lofty rapids]

it is relevant to talk about how people do main menus, or use widgets, because you can idea of how other people do it

[sonic crest]

Save it in the game Instance?

[gentle urchin]

I typically do this

[lofty rapids]

sometimes when your programming you may "want" to do it one way, but there could be much better ways of doing said thing

[wispy badger]

this way would be cleaner

[sonic crest]

Which way

[wispy badger]

The variable has a specified type. Its not a wildcard. You cannot pass anything that isnt a WBP_Options class

Even if the object is empty it should still return this class.
In C++ it would be way easier I see

[gentle urchin]

This sounds like a very clear case for show / hide

Which widget switcher solves

[wispy badger]

I dont want widget switcher

I dont want to put everything into one container

[gentle urchin]

Youve spent more time arguing than just making it

And it would work

[sonic crest]

It's like setting up a nullptr

Here you just declared a pointer Options Widget without assigning anything it to.

[gentle urchin]

And you wouldnt know except while looking at the code

[wispy badger]

I asked a simple question. You stretched it out to alternatives

[gentle urchin]

The answer was no

You dont get a class from a nullptr

The End

[wispy badger]

In which case it would still return its underlying type

doesnt matter if the object is empty

the type should be saved in the variable

[gentle urchin]

It does.

[sonic crest]

It's the same thing in C++. You STILL need to point to something.

[gentle urchin]

Its not.

[wispy badger]

Not really. When you have a nullptr you still have a type

that you can use

doesnt matter if the object is empty. The type is saved

[sonic crest]

Yeah but it's still nullptr, it won't return anything

[lofty rapids]

is there a get type in c ?

i never heard of it

but maybe c++ unreal stuff some sort of magic

[wispy badger]

decltype but idk if thats a c or c++ thing

[gentle urchin]

So what problem is your mutual exclusivity solving anyways

[sonic crest]

Both

[wispy badger]

actually no, thats a c++ thing https://en.cppreference.com/w/cpp/language/decltype

doesnt matter. UE uses C++

[gentle urchin]

And the answer is still no, in the bp context of your question

You wont get the class from an empty pointer.

[frosty heron]

Empty ref = won't return any class

[wispy badger]

shame

[frosty heron]

period

[lofty rapids]

use another variable

[frosty heron]

just drop the widget into the main widget and hide it

[gentle urchin]

They dont want the ref dependency

[frosty heron]

for a main menu?

[gentle urchin]

Yepp

[frosty heron]

oh well

[gentle urchin]

Gonna shave some fps off or smth

Id just have 2 class vars in my hud class

And spawn them depending on

Store them in a generic user widget pointer

Gg done

[wispy badger]

having them all in one widget would be faster but it would also be a huge inconvenience for me

so yeah, I'd just use 2 variables for each class with references

[frosty heron]

it's nothing to do with being faster to me

just easier to view the hierachy and flow

[gentle urchin]

Id be interested to know a out the inconvenience tho

If its actually worth even considering

I highly doubt it

[frosty heron]

Want to go back to some page? pass it to master widget and let it handle where the player should go

[gentle urchin]

But i could be wrong

[frosty heron]

that;s how I do it

[sonic crest]

Same ^

[wispy badger]

having separate panels in separate blueprints gives you more freedom and comfort than having to manage dozens of other elements in order for your gui to even fit the screen

[gentle urchin]

They can still be in seperate bps

[frosty heron]

^

[gentle urchin]

Just contained in the same

[wispy badger]

ehhh. how would that look like?

[gentle urchin]

Widget a
Widget b

Widget c -> contains widget a & b

[simple echo]

I'm fairly new to UE (fled from Unity), I'm not really sure how to use splines 😅

[gentle urchin]

Welcome !

Id think 2 to 4 points, looping,

Fixed tangents

Probably 4

And just align it with the aim direction

[frosty heron]

@wispy badger

[gentle urchin]

I usually speratae aøl my widgets into different wbps

[frosty heron]

that could be your WBP_Settings, WBP_Exit, WBP_NewGame

[gentle urchin]

And usually part of a master bp

For the shared functionality stuff

Window animations and what have you

[frosty heron]

me too

I need the master widget to control the state of the Menu. Setting or New Game doesn't need to know the existance of each other. Simply let the master widget keep track of the state and let it control the navigation

[gentle urchin]

Yepp

Delegates for "return"

Widget switcher in the main widget for the options menus and 'main ' main menu

[wispy badger]

how about overlapping guis and their behaviour when game starts? I understand this concept. It was the only way to create guis in unity (came from unity due to their... you know) (apart from using scripts).

[frosty heron]

You can control overlapping stuff by collapsing the widget you don't want to interact with

or using the widget switcher is obviously the better choice

but I haven't use what the cool kids use

if you ever need to debug widget, look for widget reflector

[wispy badger]

I mean, when the game starts every gui is initialized with their default values (overridden by some settings and BPs). Would I use BP to hide the guis or is there an option to do it by default?

[frosty heron]

from your master widget, add the widgets you want. New game, Setting, exit, etc

[wispy badger]

master widget bp?

[frosty heron]

U can select the one you want to hide. Lets say the WBP_NewGame. Select that, go to vissibility and change it to collapse

It's just a name for a BP that contains all the widgets

[wispy badger]

but that would make the gui invisible in the editor. I mean the gui be visible in the editor while keeping it invisible in the game. BPs are the only way I assume?

[frosty heron]

not sure if I am on the same page

oh you mean, you are just ticking that eye icon

yeah that's not it

[lavish rain]

Hey everyone. I'm trying to control a projectile's (ProjectileMovement component) velocity mid-flight (Possibly by reducing and increasing its acceleration). I can't for the life of me, though, find a way to control the acceleration values. Where can I access those in BP?

[frosty heron]

You want to set the visibility in the default properties

[wispy badger]

okayt, so we were talking about 2 different things haha

[wispy badger]

would it set visibility in the game only?

[frosty heron]

Yes

for editor, you can click on the eye icon to toggle vissibility (in editor)

[lavish rain]

I want to make a projectile that starts off with average speed, slows down, then ramps up massively

[gentle urchin]

Do some nice timeline with a curve for its max speed

Have some braking friction

And possibly low/no gravity 😄

[frosty heron]

@gentle urchin Is it even possible to do
AActor* SomeActor = nullptr;
auto TheClass = SomeActor::StaticClass; ?

[wispy badger]

You cant do :: on an object

[gentle urchin]

I dont know tbh

[frosty heron]

I've tried getting class bp on nullptr, it doesn't print anything except when assigned a ref

[gentle urchin]

Probably not

[floral stump]

is it possible to disable or make that outline transparent when selecting an object?

now i am trying to remove the gap between two objects, but that outline is not letting me to do it with comfort

[gentle urchin]

You can use the extra views to help you out

Top down, side and front 😄

4 split window

Doesnt remove outline but helps with allignment

[floral stump]

yeah it does but this is a landscape

[floral stump]

merging tiles are trouble because of this outline

[sonic crest]

Click on Show -> Advanced -> untick Selection

[floral stump]

amazing

thank you very much

[sonic crest]

🫡

[wispy badger]

Can I turn off an animation in editor so that it wont take effects in the editor only? I want the animation to play normally in the game but dont want to manually set the opacity to 1 when I open a widget (fade gui animation)

[dim agate]

Isn't there a command to make the ends of two objects flush with each other?

Rather than having to eyeball it.

[sonic crest]

Not sure I understand correctly

You want to make the animation happen only in game and not in editor?

Or?

[wispy badger]

yes

[gentle urchin]

You can also deselect the anim in the editor, if its state is troublesome

[frosty heron]

if I understand it right. Create an anim call Default. Make sure it's at the top

just have it empty

whenever u open the widget, it should be on that state

[wispy badger]

oh right, forgot about that. Thanks!

[sonic crest]

I not sure if there's something but, I'd just disconnect the animation thing

[wispy badger]

I would manage all widgets in the root widget, right?

[frosty heron]

btw seems like the only way to get a class from a pointer is to use ->GetClass()
But obviously it crashed when the pointer is null

[wispy badger]

i.e. from root widget I have to attach event handlers etc.

[frosty heron]

Depend on what you are doing, but for a main menu that's how I would do it

Your widget can of course have another sub widget which is handled by it

For example a setting menu might have different pages, that would be something Wbp_Setting handled

not wbp_master/ wbp_main menu

You can see here at the end, I switched to different page in the settings. That's handled in WBP_Settings
WBP master would handle request when a page is finished (eg player wants to go back)
WBP master would then close (hide) the settings and show the main menu

[elfin lagoon]

why color dont change this way?

[thin panther]

you haven't set a parameter name

there is no color called "None" there

[elfin lagoon]

which name must be set then?
"Color" dont work too

[nova scroll]

Hello everyone.
I just started learning and I wanted to learn how to create a game from scratch.
I was thinking about a maze from a top down view.
I used blueprints to make move the character but now the real question: how can I rotate the character in the direction he is going?

[lavish rain]

Does a projectile always stay at its max speed no matter what?

[gentle urchin]

No

Its accelerating by force applied - breaking friction

Also has an initial speed

[glossy cloak]

I'd suggest looking through the template projects to learn how those are made, then use that knowledge in your own project.

[lusty hedge]

Can ChaosVehicles used to make tanks?

Im having a hard time figuring out how to get my player controller to be slanted while on a slanted surface

[nova scroll]

oh right, thank you mate 🫶

[lusty hedge]

move witht the terrain

[thin panther]

a quick google suggests yes

[lavish rain]

How do I change Force Applied?

[lusty hedge]

A quick google for myself is less effective

What im getting at is i dont understand at all how Chaos vehicles work

and most tutorials assume you already know a lot

[gentle urchin]

Common physics starting point

[fossil pebble]

Hi everyone im trying to use HISM comp. but the generated meshes only visible at runtime not in editor viewport when im trying to use it. Does anyone has a solution for this?

[lavish rain]

Is that a node?

[gentle urchin]

Huh

[lavish rain]

By Phyiscs Starting point, do you mean right clicking the Blueprint, and going to the Physics tab?

I think that's what you meant

[gentle urchin]

No I just ment its a common theme for people starting with physics

[lavish rain]

I'm sorry if my questions are a bit dumb. I'm a total begginer

[gentle urchin]

They're expected to know a lot from the get go

[lavish rain]

Ahh, I see hahahaha

[gentle urchin]

They usually show if you select a mesh and add the instances in the component defaults

[glossy cloak]

Are you in game view? (G key)

[fossil pebble]

no im not

[fossil pebble]

Everything works well when I swap HISM with ISM, but I want to stick with it for performance reasons. I am on 4.27, and when I was developing on 4.26, everything was still okay.

[gentle urchin]

I dislike the hism

Its less performant for me

Along with its fun auto swapremove functionality which might throw you off guard

[fossil pebble]

Yeah, it's hella buggy. Two years ago, I was trying to create a crowd system that could animate with vertex animation, and HISM didn't work. My animated meshes started to flicker, and I had to swap to ISM again.

[gentle urchin]

Exactly the same

So i stick withnism

Got vertex anim manager the other day

So im gonna play with that

Its also using ism as its base

[fossil pebble]

Looks like we're going to have to write our own HISM one day . Epic doesn't seem to care about it at all for years.

[gentle urchin]

Is it worth it for the lods?

Culling can be done separatly if needed

[fossil pebble]

Not exactly sure is it just enough or not.

[timid bear]

hello guys! I have a question) is this channel good for asking help here?

[lunar sleet]

depends on the question, ask it

[timid bear]

I already did an input verifying (gamepad or keyboard), but also I should check is this game runs on a mobile platform or not.
How I can check this only with a blueprints?

[lunar sleet]

iirc Cropout Sample Project has a way to do this, I'm checking now, just gotta wait for the shaders to load again lol

[timid bear]

got it) It would help a lot

[lunar sleet]

they're using the old input system, but you could prly adapt this to EIS easily:

Key Switch here is a dispatcher that several things bind to, from the player logic to the UI

oh wait, I guess you already did the input check part mb

I think for mobile support they just make heavy use of soft refs but I'll check again

[timid bear]

Thanks a lot!) I thought it should be harder a bit)

[lunar sleet]

here:

ig there's already a built-in function for it

[gentle urchin]

Basically if ! Windows? 😅

[sand yacht]

hi, how can I attach navmodifiers to each spline mesh at runtime?

I found a picture of someone pulling off exactly what I would like to do

but not sure how to achieve this

[gentle urchin]

I cheated

Using isms

With a different navclass

[sand yacht]

im not sure what an isms is

[gentle urchin]

Instanced static mesh

[sand yacht]

ohh right yeah, im using instanced static meshes on the spline

they get added at runtime

but im not sure how to add a navclass to them

[gentle urchin]

Its a property

On the component iirc

[sand yacht]

its greyed out for some reason

ah got it

had to tick is dynamic obstacle

thanks a lot!

[timber crystal]

hello you guys
YOU ARE THE BEST
every time i need help you help...
God bless you guys

Now i need a flying AI that trys to catch me when i overlap his trigger box

this dont work whhhhhhhyyyyyyy 😦

[gentle urchin]

Flying?

Nav aint 3d

Its 2d

Needs plugin for 3d

Or custom implementation

[timber crystal]

its a 2d game 🙂

ohhh but i do not set a nav mesh

its a 2d platformer game pixel art style

[gentle urchin]

2d platformer...

Sounds very much like it needs lateral movement

[timber crystal]

can you help me with that ... 😦 ?

cant find a good tutorial on yt

[gentle urchin]

Id probably start with basic vinterp

Towards target, on tick

[timber crystal]

okok to much for my litle coder brain but i can show you how i cheat that with a projectile movement 1 moment

[timid bear]

so clean rn

And thanks @lunar sleet, it worked for me)

[timber crystal]

the only problem now he flys at the begin of play not after i overlap the trigger box

its a projectile lol

the enemy just fall down after overlap the trigger box .... thhhhhhhhaaaaaaaaaats not a flying ai 😩

is there a way to say that the "Projectile(Flying enemy)" start his moven after i overlap his trigger box

?

[gentle urchin]

Yes

By (target) IsValid

Thats what it ment to do

So on overlap -> set target.
End overlap -> unset target

[timber crystal]

leeet me try thanks 🙂

[lavish rain]

Heyo! Thank you for the help, I figured it out!

[gentle urchin]

How did i help 😆

Glad it helped, whatever it was

[timber crystal]

is that waht you mean ?

[wispy badger]

Can I prevent BP_FirstPersonCharacter from spawning and instead spawn it manually?

Its a player controller from UE's FPS starting content

[lofty rapids]

you could set the default pawn to something else

and possess your character after

[wispy badger]

How would I do that after loading the level?

For setting default pawn, no problem. Just set this to None I assume

[gentle urchin]

On tick, not there

Before the vinterpto

[wispy badger]

❤️ will try that in a sec

[lunar sleet]

TIL Niagara Systems have a custom time dilation function 🤦

[zealous moth]

is there a way to select stuff through other stuff using the marquis?

[frosty heron]

Pawn possession via game mode is per level basis

[proud salmon]

Why does no one talk about the world partition system and data layers more? There seems to be next to no information on the subject and the information that does exist (like Unreal docs) is out of date and doesn't work.

Is there an updated version of this that can be used in 5.3?
https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/DataLayers/AddActorstoDataLayers/

If not, what is the "go to" solution for adding actors added during runtime to a data layer so you actually use the WP system properly? I know there are some hacky workarounds but there's gotta be an actual way to do this properly.

[spring walrus]

can someone help me with some issues i have regarding making a fps cap

[frosty heron]

T.maxfps X

[spring walrus]

i mean like making a main menu options tab then fps cap

[frosty heron]

Same deal

[frosty heron]

The command still the same

Not sure about the goal tho. Capping fps normally a shit show

Why not opt to deliver smooth experience instead

[spring walrus]

wdym

[frosty heron]

Why capping ppl frame rate? When they can go 144 but Ur like nah let's have u enjoy half of the fps

[spring walrus]

im not capping it im giving them the choice to put for example 30-60-144-unlimited like in most games

[frosty heron]

They will hit the maximum fps they can attain if you leave it be

[gentle urchin]

Max fps makes my gpu go hot

I prefer v synced

[spring walrus]

yeah but sometimes people have issues when its at unlimited and it would be nice to give them the choice

[gentle urchin]

Freesynced

[frosty heron]

I'm g sync

[gentle urchin]

Red team allows you to cap fps in the adrenalin suite tho

So i dont really care what the games offer^^

Not sure if nvidia allows that but i guess ?

[gentle urchin]

Can you cap fps from nvidia software?

[frosty heron]

No idea, never come across my mind

[gentle urchin]

Kk^^

[frosty heron]

Fps is king for me

Even if I have to lower the graphic

[gentle urchin]

I generally agree

But like league giving me 240fps on a 60hz screen

Only to churn my gpu fans to max

Gives me very little 😅

[frosty heron]

My eyes are not accustomed to 60 fps anymore. Kinda hate how all souls game capped at 60

But yea I see the point to cap fps

Never thought about fan running hot

[gentle urchin]

I went for early ultrawide so didnt get the 144hz

Never had the actual experience of it. Yet

Next upgrade is that tho.

[frosty heron]

Monitor gets cheaper and better, u will experience it on next upgrade 😄

@spring walrus assuming you have populated the screen res etc. What might you be looking for?

U can prob hard code it with an array of strings

[spring walrus]

theres a few things i need changed

[gentle urchin]

Screen res can be auto generated

From grabbing supported resolutions

[frosty heron]

Yea there is node for that

[gentle urchin]

Even unsupported ones

[frosty heron]

Don't know about fps tho

[gentle urchin]

Isnt that just console command

T.maxfps

[frosty heron]

I mean how to determine what fps the machine can tank

[gentle urchin]

Ah

Benchmark it

[frosty heron]

True

[spring walrus]

like the arrow becomes greyed out when you can't go more to the left/right and like fps cap so you can choose between the amounts i want

[gentle urchin]

I prefer loops

[frosty heron]

U r not able to do that with your scree res atm?

[spring walrus]

wdym

[gentle urchin]

If index == last index then disable right

[frosty heron]

U got Ur screen res etc already are u not able to chose between different option by selecting the arrow?

[gentle urchin]

Id just modulo the index with the last index going up, making it loop 😅

[spring walrus]

i have that made but im talking about the fps cap the screen res option works perfectly

[frosty heron]

It's just going Thru an array.

Left side --index
Right side ++index.

If == length . Index = 0
If < 0. Index = last index

[frosty heron]

But it's the same logic for the arrow

[spring walrus]

isnt that for c++?

[frosty heron]

It's just algorithm. U can easily do that in bp

[spring walrus]

and how would i do that

[thin panther]

Read it and use the corresponding nodes

[frosty heron]

Well I can't show more, gtg to work but the logic have been posted above

Try it and if u get stuck, ask the peeps here

[spring walrus]

yeah alr well i dont really even know where to start so idk

[frosty heron]

Do you know how array works? I would start from there if not

Every single element in your setting use arrays

[spring walrus]

its hard to explain but idk where to put the blueprints or which

like for the blueprints i have already i started by clicking on on clicked

[frosty heron]

I'm out of time. If no one help, look at tutorials. Try to understand array. If you are still stuck, I will show u a simple code once I'm done with work

[spring walrus]

thank you

[frosty heron]

But I rather u do the handwork cuz if u don't understand array u will just get stuck again

[spring walrus]

ur talking about this?

[frosty heron]

Nah that's just the button

[frosty heron]

Break down Ur problem, talk to Ur self how u want things to be

If I click this arrow, then I want to display next element. If the element already the Max and i hit this arrow. Show the first element

[spring walrus]

i want it to be greyed out when i cant go any further and not clickable anymore

[frail onyx]

Anyone know how to make a like a singular BP that acts as a button i can press and it'll activate something, but have it so it's like 2 different things i can press to activate different things within the one button bp, kinda like a button panel with 2 different buttons on it

[gentle urchin]

Right button enable = currentindex < LastIndex

Left button enable = currentindex > 0

[spring walrus]

thats blueprint?

[gentle urchin]

In textformat,sure 😅

[spring walrus]

wdym right button enable arent i suppost to use arrays

[gentle urchin]

You are

Array for the fps limits

[lunar sleet]

if you're talking about a UI button, there's button widgets you can use, see #umg

[spring walrus]

not the buttons?

[frail onyx]

kinda similar to the functionality of that but like an actual physical button which uses a linetrace to see if im interacting with it

[lunar sleet]

so make an actor that looks like a button, place it in your level

[frail onyx]

i have that but i wanna make it so it looks like a button panel and when i look at different parts of it and interact it does different things

[gentle urchin]

Both... array of fps limits affect the widget buttons ...

[spring walrus]

what variable type

[gentle urchin]

Integer id say

[lunar sleet]

make more button actors or use multiple static meshes and line trace to individual components

can prly also use Child Actors, just don't use Child Actor Components

[spring walrus]

well im a very beginner developer so ig ill just wait till im better to make harder stuff

it wasnt really my main concern right now anyway it was just fixing the fps cap i made

[wispy badger]

Is it possible that custom GameMode disallowed the usage of these fields or did I mess something up?

[queen heron]

is it possible to replicate the Child Of constraint from blender into unreal engine?

if so, how?

[frail onyx]

do you know how i could modify my existing system to make this work?

[lunar sleet]

Sure

Just do what I told you

[frail onyx]

uh im not sure how to make it line trace for indiviual components exactly

i tried just switching the hit actor with hit component but that doesn't seem to work at all

[lunar sleet]

That’s exactly how

You cast to hit actor, then grab hit component, check if it equals the one you want, go from there

[sonic crest]

Modify your game mode stuff in your game mode class

[frosty blade]

Hey guys, i have a noob question. I need to increase a value inside a Gameplay ability but it doesnt seem to work. Does each input key call use a new instance of it? If so can anyone give a me a suggestion on how should do it. Im trying to make a combo system and each input should use the next montage animation

[frail onyx]

hmm i still couldn't seem to get it, i switched the hit actor to hit component on everything and it isn't working, im not sure im understanding it correctly

[lunar sleet]

Hit actor > cast to the corresponding BP -> get the component you want to check, == against the hit component, if True …, and so on

[wispy badger]

The gamemode class is an empty blueprint. There is nothing in it. Strangely enough it worked fine directly after setting the gamemode to my custom one but it doesnt want to work now

[hollow bane]

hey there

is there anyone who can help me?

i am recieving a value from touchdesigner, 0 or 1. i want to make a blueprint that allows me to "simulate" a mouseclick if the recieved value is a 1

how would i approach that?

[lunar sleet]

by not doing it. just call the same function the mouse click would

[hollow bane]

how would i do this? i am using an event to make a score on click on a specific mesh

[lunar sleet]

Add Custom Event SetScore

onClicked call SetScore. On whatever else you want to "simulate click", call SetScore

[hollow bane]

im sorry im very new, could you elaborate a bit more?
Maybe for context this is what i have so far from touchdesigner coming in

[lunar sleet]

you've been in this discord since 2022, what happened lol

[hollow bane]

i never did anything meaningful 😦

but i am trying to learn 🙂

[lunar sleet]

k, well I'm not sure how to explain this better but also idk what touch designer is.
If you want the same scoring logic to happen when you click as well as when you receive your touchdesigner msg:
Create a new event. Put the stuff that's currently in your ActorOnClicked event in it. Go back to the ActorOnClicked and call said event instead of having the entire logic in there. Call that same event on your touchdesigner msg side.

[lime basin]

am I doing it wrong? 🤔

[lunar sleet]

hard to tell based on what you've shown. #umg is more suited for widgets, but all I can say with what you've shown is make sure your return value is between 0 and 1

[tranquil wadi]

Hello there was hoping someone could help me with what I thought would be a super simple process. I have imported a Paragon character into my UE 5.3 world just for placeholder purposes. Plus I thought it would help teach me how to work and navigate Unreal. I have gotten just about everything to work however I cannot get the movement set up to work with WASD. Should I just SS the BP? Or is there a more better way to view it?

[serene wharf]

screenshot is fine

do you have keyboard inputs setup?

[undone bluff]

you can share blueprints with https://blueprintue.com/

but screenshot should be sufficient here

[quiet coral]

I am using the ninja plugin and when the player walks on walls, the roll of the camera does not stay aligned with the capsule component of the player. What should I look or do to fix this error?

[tranquil wadi]

Here is the BP after updating it following a YT tutorial. It worked in the video but for some reason it's not working for me. Everything else from Camera movement, Melee, and Jump I replaced myself cause the video didn't show that all works great.

[serene wharf]

this code is for rotating your player camera

the "Add Controller Yaw Input" node (the blue one) rotates your camera

[undone bluff]

yea that's adding control rotation, you want to call add movement input

that is what the movement component is getting its input from

[tranquil wadi]

holy cow that makes sense, let me show you guys the movement portion then. I dunno why it never accured to me that the one in the "movement" box would be actual movement lol.

I been fiddling with the wrong section for well over an hour now. humbling indeed.

[undone bluff]

you can get your forward vector from control rotation Z

give me a sec

nah you can get the right vector from it as well just fine

had to try to make sure

what strikes me as odd is you are moving with the right thumbstick

[tranquil wadi]

Right let me double check the video real fast to make sure I'm not causing confusion. I been hard focused on the previous part without realizing it.

[undone bluff]

and the x and y axis might be switched around but not sure

so is this not working?

[tranquil wadi]

Okay here is what happen, I found where the issue started. He looked up this Event

However I don't have that showing on my end. That is a SS from the video.

[serene wharf]

that is an event the guy in the video made himself

[undone bluff]

yea that's the old input system and you set those events up in the project settings

you probably want to learn how the 'enhanced input system' works

it's much more convenient to work with (and not deprecated)

you can copy the setup from the third person template project for a start

[tranquil wadi]

I see, Well then I will go ahead and scrap using this Character. I will look up some Tutorials on the Enhanced input System. Can I add onto that system say for example Eventually I want to create a small ability bar using 1,2,3,4 then F to fire them off?

[serene wharf]

you can do anything man, thats whats so cool about making games

there is basicly no limitations

[tranquil wadi]

have no experience at all programing so was hoping BP could help me.

[undone bluff]

though keep in mind in many cases you might want to let the player controller receive input and decide what to do with it instead of the actual character

that's the most flexible setup

[serene wharf]

true

[tranquil wadi]

I appreciate that, am dying to try and create a game this is the only thing holding me back lol.

[undone bluff]

epic doesn't do this in their example content for simplicity

[serene wharf]

but in a basic game putting input inside the chacater is fine

[tranquil wadi]

I will have to look up how to do that too then lol. Let me make a list of what to do then.

[undone bluff]

don't worry about it for now, just keep it in mind

[serene wharf]

yea it can be frustrating in the beginning when everyting is new but when you get the hang of it the possibilities are endless

[undone bluff]

I can give you a very basic rundown for this

[tranquil wadi]

I will take any help offered for sure. I have a deep motivation to learn. I'm sure it's not just me but I have come and gone trying to do these things. I have tried to do these things on my own buying Udemy courses for mostly Unity stuff. I have finally reached a point where I just need to get involved with like minded people.

[faint pasture]

BP is still very much programming. It's basically a visual wrapper on C++. Just gotta take it slow, you are NOT going to make your dream game first shot.

Start with something super simple

[thin panther]

Yeah. Your first few projects are going to suck, hard.

And thats ok. You're learning, and being able to look at those first projects and see how far you've come is an amazing feeling.

Things take time, it can be a long journey, but good things take a while 🙂

[tranquil wadi]

Appreciate the advice I have already crashed that dreamship lol. It caused me to step away for a long time. That's why I figured just getting a Paragon Character up and rolling then working on its Melee, then skills/animations would help get me in the door. I seem to have started off wrong again, Which is why I just said enough and reached out to you wonderful people.

[thin panther]

Sorry for that ping, bloody mobile. Clicked your name and post at the same time 😆

[thin panther]

Definitely a lot to chew off first. Id break this up a bit.

Work on some combat things separately. Learn how to use animations separately, then learn how to combine them

My personal reccomendations for starter projects don't touch more complex things like that at all.

For example, taking something like a simple platformer from concept to final build can get you used to programming, level design, animation, and character integration all in a quite safe and easy environment

[undone bluff]

learn the basics of UMG/Widgets, create a slot widget, create in it a function or event for selection and deselection as well as a button prompt, you can make this a public variable that you set in the ingame hud or depending on keybindings.
Create a widget to house your ingame hud, create in it a horizontal box to keep all your slot widgets and store them in an array (you can create the widgets at runtime if the amount is variable), keep track of which one is selected and call their selection function so they can visually represent that state

now you need to assign abilities to slots somehow, this can be in the slots themselves as a struct array which stores slot and corrosponding ability

or you just store them separately just make sure they share an index

uh it's a lot

hopefully this helps you know where to start looking though

[tranquil wadi]

haha yea but I copied it to a notepad! So I will be able to follow along when I get to that point. I really do appreciate it from all of you. I didn't expect to get any responses so fast especially not this level of help. it's a lot to take in knowing it's not going to be a quick process. Wish I could of started this journey when I was in my teens when I had so much free time lol.

[undone bluff]

for the rest of the picture you'd need to use the native HUD class

[tranquil wadi]

Always wanted to make a game and live that life. But now im stuck working a press untill further notice XD.

[undone bluff]

it's something instantiated by the gamemode

and it's where you should be managing your hud widget

you can get a reference to it from the player controller

[turbid pecan]

Hey why would calling "length" on an array tell me theres one member, but if i then loop over it i get nothing..?

Like I am using a get node for the array and if i do a print on the length before the loop, itll say "1", but when I loop, its like theres no array members

[tranquil wadi]

Ah okay copying that down too then.

[undone bluff]

in the player controller you'd have the enhanced input action for, say, slot 1, and on input started you'd use a blueprint interface function with an integer as input to tell the hud class to switch slots to the corrosponding index

[tranquil wadi]

I'm also gonna look into doing this thank you for suggesting this route.

[undone bluff]

and the hud class would manage the actual hud widget and handle switching the slots from there

I think this is all probably super overwhelming for someone starting out

you can get this working much easier by not caring about flexibility and scalability

create hud widget in the player character, cast to it and get a reference to the slots that way for example

don't get demotivated by doing things properly

[tranquil wadi]

It's hard to wrap around but I trust you and know that I do not know nearly as much so I'm copying everything down and going to google an read every bit I don't fully understand XD I don't get this kind of 1 on 1 in a tutorial video. I'm all for this.

[undone bluff]

just get them working first

most tutorial videos and assets are setup in a way that would immediately fall apart if you tried to put them in any larger game

learning to do things nicely is the endgame

if you're doing a small one year project none of this usually matters

[tranquil wadi]

Yea I think I understand that now. I thought if I could get at least the Paragon character to work it would boost moral and I can add on the skills I got a VFX pack free from the market place I was gonna use for fun. Sadly that all fell apart. I wouldn't mind getting a small adventure game going with creature AI and a few game mechanics but I think even though from an outside perspective that seems miniscule but I think I'm being humbled and learning it's still quite a lot of work.

[undone bluff]

but it's something to work towards for that one big passion project you maybe want to make one day

or if you plan to work with other people/in the industry

[undone bluff]

create a new project from the third person template that comes with unreal

it has the enhanced input system setup

[tranquil wadi]

there is a soft and main end goal soft goal would be to get hired in so I can stop working in a factory setting and put my college degree to use. Main goal is to create a game that I would want to try and see if others would enjoy playing.

[undone bluff]

try to understand how that works with some guides and use it as a starting point

[tranquil wadi]

So the Third person template would still be a good place to start? That cuts out a lot of the beginning work which is always a plus.

[undone bluff]

definitely know how it's setup so you can do it from scratch, that's a huge boost to confidence

it's relatively well done

even has leg IK

the only thing that's an issue is the character movement component

you kinda just hand it input and it does its thing including replication and client side prediction

and it's some several thousand lines of c++

scary thing haha

I heard it's getting replaced with something nicer in 5.4 though

[tranquil wadi]

Lol, yea I have seen C++ code before. I tried to take C# classes for Unity but that kinda died off.

[undone bluff]

once you are very familiar with blueprints getting into unreal c++ will be a breeze

you'll already know 90% of what you need

[tranquil wadi]

That's good to hear. I quite enjoy blueprints. I dunno why it works better but visually connecting and reading everything just works for me.

[undone bluff]

yea I enjoy it a lot too, depends on what you're scripting

it's not one or the other either, you can use both according to your preferences and needs

[tranquil wadi]

Oh see that is good to know cause I thought you had to choose one or the other since when you start a project it asks you to select either or. I thought about using AI to help me code through C++ but eventually decided I need to learn or else what's the point.

Would, in your opinion feel a course from say Udemy or Skillshare would be a good choice? I understand everyone is different but it's something im not afraid to invest in. Especially since I want this to be my future.

[undone bluff]

eh no

there's some advanced courses that are okay, paid beginner courses usually suck

you probably want to start here

https://dev.epicgames.com/community/unreal-engine/learning

[undone bluff]

I feel like this also holds true for assets, I bought several 100+ bucks assets with professional presentation that turned out to be very poorly set up. on the other hand I learned a lot from free ones especially open source plugins

always look at free options first, sometimes they are genuinely the best there is

[tranquil wadi]

I didn't even know this even existed.. I will look into this. Awesome, thank you for this site. So far I have not dumped anything into Assets. I have a strong grasp on Blender and can model at a basic level. I even learned Maya, Zbrush, and Subpainter in college. However It was not the best taught way. So I only have a grasp of mostly basics. But most of what I know is through Unity due to a professor teaching us in that.

I always come to this cliff of realization.. I can make all the models and assets I want but nothing is done without coding. So I found out about BP and here we are lol.

[undone bluff]

blueprint communication is an overlooked essential

it's the basis of everything you will be doing scripting wise

try to get a good grasp of that as soon as possible

[tranquil wadi]

For sure I understand just how important it is. I envy you guys for knowing this stuff. Truly is incredible you can actually make your own games.

[hard smelt]

hello, I'm trying to use an animation montage on the starter third person mannequin. the animation plays on trigger, but the feet are fixed to the ground. I have the slot set to "FullBody". Anyone have ideas on what the issue could be?

[undone bluff]

you are probably applying leg IK after your animation montage

[hard smelt]

yeah, so maybe it's the ABP_Manny_PostProcess ?

[undone bluff]

yep

that's the issue

either put the slot afterwards or make another slot

[hard smelt]

I tried putting it to the very end of the animgraph for the postprocess, and still get the same behavior

everything is default with the anim graph aside from the slot

this is the pose I want. the upper body poses correctly, but the feet are planted center like IK is being forced.

before using the anim montage, I was just using the anim sequence, and playing it directly from the blueprint class.

[undone bluff]

I have no idea how the template AnimBP is set up, but I don't get why you put the slot in the post process

[hard smelt]

it works!

thanks

I thought there were 2 ABP's, and they were chained together, so I put it in PostProcess thinking it would be last

ABP_Manny and ABP_PostPorcess . I guess the PostProcess is just a sub reference and actually ABP_Manny just calls it?

[undone bluff]

it should be a linked animbp

[tranquil wadi]

@undone bluff Gonna let you go, and head off and do some reading an watching of the dev link you sent me. Appreciate all you have done. I'm sure I'll be back fairly soon lmao. I don't have much time before bedtime for work in the AM so gonna take this time to work on some of this stuff. @hard smeltGlad you got it working, congratz!

[hard smelt]

actually, I was lost. the reference viewer connects them to 2 different SKM's. They are not connected in any way I think

[undone bluff]

I honestly haven't had a look at the template since they updated it in UE5

and before that it was a single ABP without IK

but ABP_Manny probably accesses the post process using an anim layer interface

[hard smelt]

yeah, just trying to familiarize with UE5. I've dabbled since UE3, but never really commited to a project. now I'm trying to spin up a basic prototype as a hobby to remake a legacy game

[worn tartan]

I am looking to interact with this tub. I want to be able to attach it to my character when I approach it from the side in the screenshot, press a button to attach it, change the animation to the push animation, and be able to run it around the screen. Then I'd like to be able to detach it when I press the same button. There will be several types of objects that the character will be able to push around the screen but I want to start with this one to learn. Do you know of a good solution/tutorial I can follow or some basic guidance you can give me?

I know there are some tutorials out there where it shows you how to push an object but I need to steer it left and right as well.

[vague dome]

I have a camera attacked a spring arm on my character, and i want to find a vector location (green dot) that is based on a variable distance (red line) from the player horizontally. The point should always be the horizontal forward vector of the camera (blue) but the distance needs to be fixed from the spring arm root (yellow point), independent of the pitch of the spring arm.

I am struggling to figure out a decent way of doing this where it's not leading to wierd offset issues

i do not have any spring arm lag, but it still seems to offset wierdly when i rotate the springarm

[gentle urchin]

Break it down into tasks..first interact, generally. Interface or component. Id lean towards component as we're already needing statefullness (pushing tub)

Steering is much like regulae steeeing really. Id probably have an animation blendspace for the steeringneffect, and skmoly apply some delta rotator while steering.

Next would be updating the anim. This might be its own anim state, or overlay. Reading out the steering delta

[worn tartan]

Ok awesome thank you! I will make note of this and give it a shot

[spring walrus]

can someone help me on how to make the buttons greyed out when you cant go any further

[lunar sleet]

I think you need to disable them, ask #umg

[spring walrus]

Thanks

[ashen compass]

Are object references in the vars of a BP nulled out automatically when the BP is destroyed?

[lunar sleet]

good question. Maybe not until it's garbage collected but trying to access that bp will give you a pending kill error anyway so it's kinda moot

[normal crow]

Has anyone used a modular character (multiple skeletal meshes) and gotten ragdolls to work? I can not tell what I'm doing wrong here (I'm using the Set Leader Pose Component).

Obviously, the legs are not ragdoll-ing correctly. has anyone had a problem like this or have any idea what I might be doing wrong? (I'm pretty sure I'm not missing any meshes when I apply things, I copied them all from the components window).

This is Unreal 5.2

[uneven coyote]

im pretty sure this is something simple i just can't figure out but i have a jump scare with the end point with the navmeshboundsvolume but yet when the trigger is triggered character will only run in the same spot?

[wispy badger]

Any help?

[frosty heron]

Define what doesn't work?

[wispy badger]

I cannot change default map fields. They are locked for me. I changed my default game instance to an empty BP class for other purposes and strangely it worked then. But... it broke or I messed something up

Is it possible that a BP messed it up or not?

[frosty heron]

Not sure if the problem correlate with each other

Bp game mode just responsible for spawning the player

And doing more stuff behind the bg

[wispy badger]

So, why are the settings locked?

[frosty heron]

What settings

It's prob a better idea to post a picture along with the question

[wispy badger]

Well I did post it but here ya go: https://media.discordapp.net/attachments/221798862938046464/1209242988300210246/image.png?ex=65e6364b&is=65d3c14b&hm=c2b2af65c62c9256e16506af63f5ead3d144672e6cf990070cda53adf8a1b8d2&

[frosty heron]

Where exactly is this

It would help to see the window

[wispy badger]

Project settings -> Maps

[frosty heron]

K u don't change it there

If u want to change the default values, edit it in your game mode class

[wispy badger]

I could change them just fine with default (or non existing?) gamemode, hmm.
The gamemode is a C++ class. Would I need to make a custom BP class for this too?

[frosty heron]

You generally want a bp version of any cpp class you make

But regardless this is the wrong place to change it

Make a bp class out of your game mode

Then open the game mode bp class and change there

For what game mode to use , you can set it on per level basis

Via world settings

[wispy badger]

When I create a Gamemode BP class, would I have all related settings already in there or no settings at all like in GameInstance?

[frosty heron]

Apple and Orange. When you create a fresh bp, it will just inherit w.e default values the base class has

[wispy badger]

Hmm, so GameInstance inherits nothing then?
Okay, will try that with GameMode

[surreal peak]

Wdym with Inherits Nothing

There might not be much exposed to BPs, cause that's an extra step. Doesn't mean the Class itself doesn't inherit anything

[gentle urchin]

Picks up network error / travel failure at the very very least

In bp

[wispy badger]

It doesnt make anything visible to you I meant, sorry.

[gentle urchin]

The events are there

You just gotta grab 'em

[queen heron]

even tho the return value returns true, the camsocket mesh doesn't show any animated movement from the socket bone

I'm tryna make the camsocket mesh to be both affected by the spring arm and the animated bone called "TPS_Cam" so that when the player is in third person, the camera wouldn't be just static

I'm using a bone because the camera shake system doesn't have the options I need

[gentle urchin]

Class == Class runs true for subclasses aswell ?

nvm, ClassIsChildOf exists

[silent drift]

Is there a way to make a Component have a "choice" of components? E.g. I want to have a BPC_Health_Base that has all events, and so on and where I can add several events, but for enemies, I want to use either BPC_Health_Enemy_Standard or BPC_Health_Enemy_SpecialHitAreas that has the same things as the base, but with the actual logic as well. And Ideally I want to add the BASE to the Enemy Character Base, so that I can assign all events there, and then for all "children" based on that I can choose to use either Standard or SpecialHitAreas.

[queen heron]

alright, I'm getting close to what I want
now the last thing I gotta do is determine the forward vector so the camera doesn't start approaching the character when the rotation is different
tho idk how to do that one

ah, alright ok, turns out I actually need "Get Socket Transform"

so that the vector of the selected socket is Relative

tho I still seem to be missing something

X and Y still swap out depending on actor's rotation

ah, there we go, the target which I was transforming with the socket had its rotation set to world

had to use the print string to see what the Current TPS_Cam Vector variable was giving

and the values were ok

[gentle urchin]

Not easily no

You can make a component have it all, with configurable parameters for all the desired effects and generic event delegates that carry on some identifier for the specific event

But the main component must then implement all the special hit area logic

And trigger the delegate if something hit corresponds to the config of hit areas

Wether thats multipliers or weaknesses or...

The actor itself ( or a manager/factory) is usually the composer of components tho, and not a component ..

[silent drift]

Mm

Figured that out after some googling. 😄 Thanks for the answer.

[gentle urchin]

Sounds like you want some composition structure

[arctic elm]

Hello.
I want access values from a data store using a string as key. (preferrably in constant time)
This data store is a serializable file that other people can edit.
What's the best way to do it with just blueprints ?

[thin panther]

Does this data store need to be edited outside of the engine

[arctic elm]

it should be editable within the editor like a data asset by other devs.

[magic mica]

I am moving my character in the X-Y plane on a surface that varies plus or minus 25 in Z, but the transform places the character under the surface geometry every time. How do I set it to land on top?

[thin panther]

Just use a map of string to whatever, contained inside whatever you want

[stuck sentinel]

yo guys

i made an event begin play to play sound ok

then i create a collision to transport me to a new level

when i enter the beginplay sound plays

why

like everything in event tick and begin play plays again when i enter a new level

how to disable

[steady night]

hey

how would i make it so if a class string is empty it skipps that space in the text

anyone :/ ?

[normal crow]

Issue is caused by the by the parent mesh (ie the 'Leader Pose Mesh') either not having the bones or ragdoll collision of the lower half of the body.

Fix:
Ensure basemesh has all bones in the Skeleton and PhysicsAsset; use a material that does renders as invisible or has no alpha (HiddenInGame or Visible doesn't seem to work, probably due to engine optimizations or more likely I'm doing something wrong.)

[versed sun]

I think this may work
Add you Class String 1,2,3 to an array
If text is empty , it dosnt get added

[steady night]

cool

ill try it

I'm currently looking at an issue on one of my projects where the camera goes through walls. I've tracked the issue down to moving the camera (local position) away from the end of the spring arms it's attached too. As this offset is still needed, I was thinking of using a second spring arm to control the offset but this would require some additional math to calculate the rotation and length of the spring arm and camera rotation based on the desired offset. Does anyone have another other suggestions before I go down this route?

[gentle urchin]

Do manual collision testing

Thats what the springarm do anyways (on that part)

But with local offsets youd probably get interesting scenarios if you got zoom etc

[sand yacht]

Hi, I have a system where the player can rotate and drag the camera around using their mouse as shown in the picture. My issue now is that the cameramovement directions get messed up when i rotate the camera, since it still moves in the X direction regardless of the rotation of the camera

fixed, shouldve used add local offset ofcourse

okay not entirely, the X directoin works now, but up and down becomes zooming in and out after rotating

basically i want to lock the movement to a flat plane

[wispy badger]

should the gamemode be a subclass of GameMode or GameModeBase?

[steady night]

@versed sun ey

how would i change so it would add on a new line each input ?

like so ?

[lyric rapids]

When i spawn enemies at runtime they dont want to move at all on the nav mesh

[steady night]

@lyric rapids

its on placed in world by default

change it

[dark drum]

Any thoughts on how I might approach this?

[gentle urchin]

Id probably predict trace locations based on the current offset direction and verify before allowing movement there

[dark drum]

Multiple the vector you're adding by the cameras forward vector.

[dark drum]

I'll give this a try. I've got it to work with a second spring arm but the camera stutters a bit so going down this route might be better.

[sand yacht]

I managed to fix the movement on the axes, however my camera is attached to a spring arm. I also have a zoom function by scrolling the mouse wheel which extends the length of the springarm. Is there a way to increase the length of the springarm along the red line instead of on a flat plane?

this is what happens now if i double the length for example

fixed it! juts had to rotate the springarm instead of the camera in the viewport

[steady night]

What could cause this value being -50 and its not reacting to Less the 0 ?

[lofty rapids]

the code should work as you put it in

if it's less than than the branch should be true

[dark drum]

It turns out I'm an idiot. 🤦‍♂️ The spring arm has a socket offset which I should use instead of setting the local location of the camera.

[steady night]

well its not :/

[lofty rapids]

you print string the number before the branch ? and then some prints after the branch ?

or maybe breakpoints to see where it goes

[steady night]

well i am and its printing as if thje value is positive

but the print says its negative

[lofty rapids]

well the logic usually works as programmed

i can't imagine they f'd up the branch somehow

[dark drum]

Are you printing the actual value to see if it's actually less than 0? You might be assuming it should be when its actually not.

[steady night]

this is weird as hell

https://gyazo.com/ca4a99528b597ce86b65d93c089c8c06

[lofty rapids]

where is the log that shows -50 ?

the fact is it's not > 0 if the branch isn't true

unless there is some sort of bug, which i'm doubting

[steady night]

how can i get it to print on the log

[dark drum]

tick the print to log check box on the print string/text

[steady night]

aye it is

-59

50*

[steel shadow]

Hello, I'm wondering how I can make a projectile get the target place in the world so It shoots to it and not in a wall if the target is placed higher than the shooter

[steady night]

@steel shadow trajectory u mean ?=

[steel shadow]

for example when the guy on top shoots

the projectile goes straight

but not at the player "height"

Makes sense ?

[steady night]

not really

is it aiming for hes root ?

[steel shadow]

Well the projectile goes over the players head

for now the AI just rotates to the player and shoots

[steady night]

oh

how are u shooting ?

linetracing or projectile ?

[steel shadow]

Projectile

[versed sun]

you want to shoot downhill parallel with head height?

[steady night]

u need to calculate trajectory or set homing missile

[steel shadow]

I want to shoot downhill yes

[steel shadow]

hmm

[steady night]

add gravity to the projectile ?

[steel shadow]

nah that wouldnt really solve it

does homing missile locks to target ?

[steady night]

u have to spawn the projectile with the rotattion towards the target thats what u want

[steel shadow]

all the way ?

[steel shadow]

yeah

but not the target rotation

[steady night]

when u spawn the projectile just set look at rootating

could probably use this

[steel shadow]

hmm

[steel shadow]

so the target would be the player right

[steady night]

yes

or no

target is the projectile

start*

target the actor your aiming at

shooting at

[steel shadow]

Okey 'ill try something

[sand yacht]

how can I save and load a spline?

[steel shadow]

Works

aha thx ❤️

[steady night]

np

we all been there

[gentle urchin]

Oh yeah. Theres that too 😅 i forgot it existed

[dark drum]

One of the many things I forget UE already does for you haha.

[steady night]

https://blueprintue.com/blueprint/j0uuac88/

ok whattahell

it works on the 2nd one themana but its exactly the same ??? or am i blind ?

[lofty rapids]

theres no values in the > <

[steady night]

aye theyre 0 on my end..

its the site that buggs

[lofty rapids]

print string the value before the > check @steady night

it's probably not > 0

branches don't just fail for no reason

[short reef]

So, how does one get the current length of a spring arm?

[lofty rapids]

target arm length

[short reef]

No I mean the actual length of the arm at any one time

[narrow pendant]

trying to read a json file in BPs, is my file path correct like this?

Game/Content/Data/data.json
/Game/Content/Data/data.json does not work either

an online json validator tells me my json is correctly formated

[lofty rapids]

ya the target arm length

[narrow pendant]

get your character, get the spring arm component and then get the variable target arm length

[short reef]

No, that's literally not what I want, that value doesn't change

[lofty rapids]

i change it all the time

wdym yours doesn't change ?

[short reef]

No, I mean during gameplay

[narrow pendant]

if it is changing it should reflect in that var, it is what you want

[lofty rapids]

i mean target arm length is the spring arm length

you can change it during run time

like zooming in/out

[short reef]

That's not what I want, I want a value that adjusts if the spring has to shorten if it collides with anything

[lofty rapids]

you want to know if the spring arm had a collision ?

[stuck sentinel]

everything in event tick and begin play plays again when i enter a new level
how to disable

[lofty rapids]

make a boolean or some sort of variable that will branch of to do stuff for different levels, store it in game instance

[short reef]

No, it's more that I'm sending out a line trace from the camera and I don't want it to extend more than a specific distance past the player

[gentle urchin]

Distance(Get socket location , get component location )

[narrow pendant]

so you want a camera system, not just the length of your spring arm?

[gentle urchin]

If theres no current length avaliable

[gentle urchin]

They want the current adjusted armlength

Adjusted by collision

[narrow pendant]

that is target arm length, no?

[gentle urchin]

No

Lies in the name

target

Not the same as current

Or actual

[stuck sentinel]

how do i make a boolean level specific

[short reef]

Yeah, target arm length is the desired length, not the actual length

[narrow pendant]

does it not update? I might misremember

[gentle urchin]

It doesnt update from collisions

Its just a "this is the length we try to keep"

Not the actual current length

[lofty rapids]

right so what i'm saying is the game instance is persistent, so you could use some variables in there

at the end of the first level, switch it to second level stuff

honestly i like to use strings and branches

but you could use an enum also

some sort of state for your player

where you can check the value of the variable and branch accordingly

[narrow pendant]

apologies then, I was misremembering the camera stuff. sorted my json problem btw, promoting the file input to a var makes things a lot easier 😄

[short reef]

Thankfully, distance vector is a good enough workaround

I'm actually surprised there's no actual length value for spring arm, though, at least from what I can find

[gentle urchin]

Probably not bp exposed

Thats a returning theme

In this engine

[short reef]

Epic really needs to expose more values to BP

[stuck sentinel]

so i move everything to the level blueprint?

[lofty rapids]

i wouldn't do that

[stuck sentinel]

i dont understand then sorry

[steady night]

@lofty rapids they are printed before check ... they are negative O.oO.oO

[lofty rapids]

you have used game instance ?

[stuck sentinel]

no

[lofty rapids]

you know about variables ?

[stuck sentinel]

yes

[lofty rapids]

well your variables are on your player will all reset when you load another level

pretty much everything resets except the game instance

[stuck sentinel]

what is the game instance

[lofty rapids]

i believe it's the "instance of the game"

i don't much about the flow of execution

but it's run at the start, and persists even if you load levels

[stuck sentinel]

okay then for this game i will continue in the same level future games i will use game instance

[lofty rapids]

well it's just a place you can store stuff that persists across levels

like a state, currentLevel information, stuff that stays across levels

[lofty rapids]

makes no sense, somethings f'd, branches don't just fail

all other branches are working correctly ?

[steady night]

yes

this is genuin crazyness

[lofty rapids]

it's not possible that its -50, and < 0 is false

code only does what you tell it too

unless there was a bug in the engine, and i doubt branch is f'd

[steady night]

yes i know enough to know that but something is bugged out

[lofty rapids]

show where you print string the value

[steady night]

yeah just remade verything so u can se everything

sorcery....

😮

found it

i removed them and replaced with new

then it worked

i knew something was bugged

[lofty rapids]

hmm

so the nodes were just f'd

[steady night]

suppose so

corrupted or something

[lofty rapids]

makes sense, if nodes not working try restarting it lol

[steady night]

aye

still supoer weird tho

thus i have occured stuff like this before so not suprised really

[mild valve]

Hey guys, I want to ask maybe someone knows why GetRandomLocationInNavigableRadius works with bug I think in 5.3.2? Just take a look at the code and short vid. Looks like node is taking offset based on the world 0.0.0 and I don't understand why it works like that. It should search radius based on actor location, not actor location + world offset?

[glass cipher]

hello, I was browsing through Lyra project and I noticed one thing, when you try to make a blueprint class it looks different. Usually it gives you choices between "actor" "pawn" "Character" etc... but in Lyra it looks like this

I wonder if anyone knows how to achieve that

[marble tusk]

Looks like that Random Location vector is in world space. The vector visualizer is in local space, so it'll look like it's being doubled

[dim agate]

I think those are custom blueprint classes. There should be an option in your own projects to create them.

[glass cipher]

yeah but I wonder how can make them selectable Under Common classes instead of "Actor" "Pawn" "Gamemode" etc like in the picture

[dark fox]

Pick parent Class window read a list of default classes from BaseEditor.ini file which look something like this

[/Script/UnrealEd.UnrealEdOptions]
; Class picker dialog settings
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Actor", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Pawn", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.Character", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.PlayerController", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.GameModeBase", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.ActorComponent", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/Engine.SceneComponent", AssetClass="/Script/Engine.Blueprint")

You can override this list in your project by modifying DefaultEditor.ini to this

[/Script/UnrealEd.UnrealEdOptions]
!NewAssetDefaultClasses=ClearArray
; Clear the original list
+NewAssetDefaultClasses=(ClassName="/Script/MyModule.MyClass", AssetClass="/Script/Engine.Blueprint")
+NewAssetDefaultClasses=(ClassName="/Script/MyModule.MyClass2", AssetClass="/Script/Engine.Blueprint")

I am working on a turret system in a multiplayer project, and everything is working fine. However, when there is a dead character, the turret gets stuck on them. When I use the 'if character is dead' bool, it stops the turret, and I can't make it forget about the dead character. Does anyone have any suggestions for this?

[gentle urchin]

If current tsrget dies, untarget them.

Dont alliw dead targets to be... targeted

[glass cipher]

ooooh, thank you,looks like exactly what I'm looking for, gonna give it a shot!

[mild valve]

thank you!

[glass cipher]

yep, it worked, thank you so much, very fast help, cheers :3

Hello folks, hope its okay to ask, can anyone recommend a channel/tutorial to learn the basics of character controller, animation blending etc? I'm a 3d artist trying to learn how to make my characters functional in UE5 Thank you in advance

[lunar sleet]

Idk what you mean by char controller. Have you read the docs on animation?

[summer sail]

Yes I've tried to read the ue 5.3 user manual but its so disjointed I find hard to navigate

Sorry Im not sure how to phrase it, create the structure that gets controller input to move the game character

[lunar sleet]

https://docs.unrealengine.com/5.3/en-US/animating-characters-and-objects-in-unreal-engine/

Use the left panel to move through the pages

[lunar sleet]

Start by using the templates and look at how they do it, input can be placed in either the char or the player controller depending on the game type

[summer sail]

I'll give it a shot but this manual branches so hard its really hard to know what I should be reading first

[lunar sleet]

This may also help, along with the other stuff on there:

[slate fable]

How would someone go about making a dice roller for a D20?

[keen widget]

how to use name(text) to get random seed number from it?
like when in games name of world is converted to seed for procudaral generation for that world

[ashen compass]

Are you just looking for how to get a random number 1-20 as if you rolled a d20?

[keen widget]

here i made it

[wispy badger]

is there a better way to do this? Im trying to make a BP functions that enables or disables a UI widget passed to it (if its enabled then its both enabled and visible. If its disabled then its both disabled and hidden)

[ashen compass]

That’s a lot more complex than needed if you just want to simulate rolling a d20- all that’s needed is a random integer node w/ max 19 and add 1 to the result

[jolly hedge]

hi, i am trying to create a trap. I have a box collision if a character goes on it. I utilize "On Component Begin Overlap ( Box )". THe problem that occurs for me is that if my character is still on the box and moves sightly, it registers again that it has overlapped. I want it to register, then wait like 5 seconds and check if he is still there. How do i do this?

[random pulsar]

hey ,i have a basic enemy ai setup and i want to make different behaviours for others,but this one is the base,can i like make childs of this one and change the mesh, anim class and other things .

do i better create child ?will it work?

[keen widget]

. ❔ 🥲

[lost wolf]

define better, if you think better means less nodes then no, there is no easy way to make it more simple

probably the only easy way to make it better is to use c++ instead of bp
