blueprint

[thin panther]

i went into bp only knowing python and i could do it

but i did

the logic behind it is transferrable

[half tulip]

impossible without knowing the API references and what they mean. Each programming language has it's own library of references

[faint pasture]

I had never touched anything beyond a semester of java and I got some cool mechanics going on day one. You just need to know in general how programming works

[odd ember]

you don't need API references at this stage

[thin panther]

once you know one language it makes it easy to learn others

[faint pasture]

Blueprint is easy enough that you can just right click and search your way through pretty much any thing you want to do.

[odd ember]

you'll want to learn OOP and understand the principles behind it

[thin panther]

plus no matter how good you get youll likely need api references so moot point

[odd ember]

well, depends really. but languages that share paradigms, definitely

functional languages can still go f themselves

[earnest tangle]

Malbolge

[fiery ridge]

Gravity settings won't save on Project settings upon restart of the editor. Is this a known bug? Can't fix it

[half tulip]

That's like saying once you know French Spanish is easy to learn... makes no sense. They are independent languages with independent api reference libraries

[faint pasture]

That's true though. Spanish is very similar to french.

[thin panther]

SQL is apparantly a functional language so yeah screw them

[faint pasture]

Hell if you're fluent in French you can probably read Spanish enough to not kill yourself

[earnest tangle]

Yeah it actually works the same way with spoken languages

[thin panther]

you're arguaing with someone who has done this

[earnest tangle]

Spoken languages that belong to the same family are easier to learn once you know another one from the same family

[thin panther]

indeed

[odd ember]

but they are? french is easier once you learn spanish

[thin panther]

you're just throwin out buzzwords here, the point stands that anyone who knows general programming principles can achieve something in bp

[faint pasture]

In my case French was actually hard for me because I was able to sort of b******* my way through it, especially on reading. I did a lot better with Finnish since I had to actually learn it instead of just using Latin stems in my head

[river herald]

unreal automatically spawns a pawn and player controller at begin play, where do i find the function for this

[faint pasture]

Game mode

[half tulip]

not everyone is multilingual

[odd ember]

what is it with all these people learning finnish or having something to do with finland

[faint pasture]

You probably don't want to mess with the functions, but you can choose what classes are used for the pawn and player controller

[faint pasture]

My people are Finnish, that's why I did it.

[earnest tangle]

What even is the point you're trying to make @half tulip ? That you're the one special case who cannot learn blueprints properly? :P

[odd ember]

a programming language is still a language. and blueprints are still a language. so you'll have to become multilingual somehow

[frosty crane]

Got a question about mixing a blueprint actor with a data class. Hope I'm wording this right. For an inventory item, I have a C++ base class with all the data properties of an item (name, description, mesh, thumbnail). In the editor, I create a Blueprint extension of this data class filling in all the detail for a specific item (medkit). I then am creating a separate blueprint actor as the pick up actor in the world for item using the item data class as the main source of information. When I create the pickup blueprint actor, how can I specify the source data class statically on the class defaults so all instances of that blueprint are pointing to 1 single data object instance?

[thin panther]

your arguments now make no sense

you just said something cannot happen, but when someone said it can, you argue "not if theyre not multilingual"

i highly advise you just accept the advice from the people that have done this

[half tulip]

nothing with any significance will be acheived in BP without knowing the Blueprint API References

[thin panther]

sigh

[earnest tangle]

I don't know BP API references and I can make games ¯_(ツ)_/¯

[odd ember]

you're the second american here that has something to do with finland now

can't be a coincidence

🤔

[earnest tangle]

Finland is invading the world secretly through the internet

[faint pasture]

It all started with Linux

[thin panther]

if i know oop

in any language

then i can do oop in another language, after learning the syntax

its not that complex

[earnest tangle]

Many technologies that power today's internet have roots in Finland

[half tulip]

Yeah it's easy to buy blueprint assets from the marketplace but without being profecient in blueprint from learning the Blueprint API References and all the nodes and what they do it's probably going to be difficult to merge blueprint assets together without help

[grand valve]

here you go! https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/ 🙂

[odd ember]

that's... just not true. you can literally search inside blueprints for the nodes you need

[thin panther]

whether you do class x in c#, c++, java, blueprints. its the same priciples

[odd ember]

are you saying that you can't add two integers together until you know the blueprint API?

that's just silly

[half tulip]

java is nothing like C++

[earnest tangle]

@half tulip You really do not have to know the blueprint apis by heart. They are too large for that to be reasonable to begin with

[thin panther]

oh no this new language made me forget all of my vector math

[odd ember]

they're within the same paradigm. they follow the same rules.

[half tulip]

I'll pin them on my wall if I need to

[thin panther]

point is, i look at the java syntax, i can use the rules i know to make them

[earnest tangle]

If you find it helpful then go for it I guess

[thin panther]

even if the language is completely different

[thin panther]

you will 99% chance never know the entire bp library off by heart

you will still google

thats the point of an api reference

[earnest tangle]

This just reads like one of the conversations on #lounge when people are depressed about not having learned some skill when they were 5 years old :P

[odd ember]

a variable on the parent item class? you can also use UDataAssets

[thin panther]

ikr

[faint pasture]

What if we could Google.... Inside the BP editor? And nodes would just pop up? Wouldn't that be wild? Epic plz

[odd ember]

too much power

[thin panther]

i just dont get how theyre arguing with experience

baffles me

[odd ember]

we have to type in the names of nodes verbatim and just hope for the best

[earnest tangle]

What if... GitHub Copilot in BP editor

lol

[faint pasture]

That's c++ in notepad

[mild pine]

Hey guys, when a player is killed in my game it's causing the game to drop 5-10 frames per respawn. Would anyone be as kind as to see if I'm doing something tremendously wrong with my respawning logic? 😅 Been trying to fix this issue for a week now 🤦

[odd ember]

and people willingly do this

[thin panther]

but you see your c++ knowledge is useless here cause bp doesnt need semicolons

checkmate

[odd ember]

use the profiler. ingame you can use stat UObject to see where the drop is happening

[frosty crane]

Yeah. The Pickup actor base class has a class UItem* Item UPROPERTY. I want to set this on the blueprint extension to Pickup but have all instances point to a single instance of the data class (UItem).

[faint pasture]

@mild pine first of all after you destroy yourself, you don't want to have any nodes since you're pending kill. Does your respawn node even get hit?

[odd ember]

so... set it in the blueprint extension? I don't see what the problem is

[half tulip]

How long does it take to memorize the entire Blueprint API Reference library? I feel like when I do that I will be profecient enough in Blueprint to make a game without help with my logic

[thin panther]

you
wont

[earnest tangle]

you're just messing with us now aren't you

lol

[thin panther]

in one ear out the other

[odd ember]

lmao

[thin panther]

i give up

[faint pasture]

You f****** don't. You just start whipping blueprints up. It's really not that hard. You could have learned half of it by now

[frosty crane]

when I select the class in blueprint defaults and compile it just resets to "None"

[earnest tangle]

He's just trolling at this point lol

[half tulip]

I bet Tim Sweeney has memorized every node and reference

[faint pasture]

You could have had a number one seller on steam already but instead you're f****** around on discord LOL

[earnest tangle]

lol

[odd ember]

it shouldn't. that may be a bug.

did you hot reload?

[earnest tangle]

Tim is too busy climbing trees to memorize things

[frosty crane]

live coding

[faint pasture]

But has he memorized the typos?

[earnest tangle]

He just pays Gabe Newell

[frosty crane]

but i'm restarting the editor after rebuilding

[odd ember]

head to #cpp and ask

[thin panther]

plot twist of the century

[mild pine]

Oh yeah, the respawn gets hit, the Destroy Actor was after the Respawn event before I swapped it around

[earnest tangle]

Gaben made Windows 1.0

[odd ember]

@mild pineagain, you'll know more if you actually profile it

[earnest tangle]

This is an actual fact btw

[thin panther]

Gaben created the concept of Life and Death

[mild pine]

Is that made to pop something up on my screen? I typed it into the console and got no feedback

[thin panther]

wait rlly

[earnest tangle]

Yeah he was in the team that made Windows 1.0

[thin panther]

if this is late april fools imma cry

[earnest tangle]

Of course he didn't make it alone but in any case

[odd ember]

yeah you should see all active UObject derived classes give some indication of their performance

so all actors etc.

[thin panther]

nah mans a machine, they had to make up extra people so it didnt look shady

[odd ember]

no it's true

Gabe worked at microsoft before he made valve

[thin panther]

bill gates = secret angel investor?

[thin panther]

well evan is dming me now

[odd ember]

I mean if you work in the seattle tech scene you make bank

[thin panther]

time to move to seattle 😎

[odd ember]

set DMs to private

one of my former coworkers moved to cali for a nice $140k job. I'm still a bit envious

[earnest tangle]

140k in california probably means you still have to live with a roommate tho :p

[odd ember]

true, it's mid LA

[thin panther]

make that 12 lol

[faint pasture]

My buddy is at M$FT making big bucks, low level supercomputer stuff

sounds boring but a paycheck is a paycheck

[odd ember]

just to be clear this is still in the games industry

[thin panther]

ive never heard someone mention supercomputer so casually

[odd ember]

and a design position no less

[faint pasture]

That's not bad at all

Although working on someone else's game.... blech

[thin panther]

thats why you get a janitorial position and overthrow the ceo

then you get your own ideas back

[odd ember]

that's exactly how the games industry works

[faint pasture]

Then make the same game 5 times

E L D E N R I N G

[odd ember]

employers need QA people, but eventually the QA people revolt and overthrow the CEO, making it their company

the board of investors is OK with this of course

[faint pasture]

Nah I'm Indie or bust, I don't love programming or any of the work of dev, just do it to make the damn games

[thin panther]

you see i love making indie games

[faint pasture]

Prolly bust but it's whatever. Better shot than music is

[thin panther]

but i do like programming

so CS degree and some software job here i come

[faint pasture]

You mean you don't wanna get a GAME DESIGN degree from Fullsail?

lmao

[odd ember]

I mean you may as well get a games industry job

lol

I got a game design degree

[thin panther]

well techinically its a computer science for games

[odd ember]

the most I learned was from one elective and from my own dissertation

[thin panther]

but so far its been more general CS

[odd ember]

I also got a CS degree to be clear

[faint pasture]

I make more money in engineering than I'd make in the games industry. I just do this on the side and we'll see if anything comes of it.

[odd ember]

the GD was just icing on the cake

[odd ember]

more than 140k?

[thin panther]

damn 2 degrees how long did that take

i mean engineering pays absolute bank tbf

[faint pasture]

No but juniors with zero experience or CS degree don't make that either.

[thin panther]

if youre good

[odd ember]

6 years?

[thin panther]

bruh

my 1 degree is 6 years

;-;

[faint pasture]

I'm a BP bitch that dabbles in C++, probably not employable above poverty wages in the actual industry

[odd ember]

fair enough

[thin panther]

eyoo same

[odd ember]

I mean I work as a designer

or rather, did

[thin panther]

i use std library all the time but unreal c++ terrifies me

[odd ember]

now I just manage them

[thin panther]

the macros, the horror

[faint pasture]

I have visited Epic though. Just showed up and looked around while I was on a job nearby lmao

[half tulip]

Do I need to re-join Highschool and learn Vector Math before I can learn Blueprints with Unreal Engine?

[river herald]

How do i let the server know the client has loaded the level?

[faint pasture]

You can get in a lot of places with a work truck and a hard hat

[odd ember]

yes

[faint pasture]

Yes, come back in 4 years.

[thin panther]

actually unreal engine pre requisites require joining pre school again

if you dont youre in violation of the eula

so sorry bout that

[odd ember]

by asking in #multiplayer

[thin panther]

books are for NERDS

[faint pasture]

Not anymore they don't, boomer.

[half tulip]

I'm a Highscool drop-out maybe that's why i don't understand Vector math references

[dark crow]

bonk1'=??

[faint pasture]

I get my math knowledge off Tiktok

[faint pasture]

Just learn what a vector is and how the cross and dot product work and you'll be fine.

[thin panther]

pfft i get mine of seedy bathroom walls

[odd ember]

https://tenor.com/view/quick-maths-mans-not-hot-gif-11163522

[half tulip]

Can I use a calculator ?

[thin panther]

only hand built mechanical

[odd ember]

use an abacus

[thin panther]

even better

[faint pasture]

I just can't learn unless it's robotic TTS with someone poppin and lockin in the background.

[odd ember]

using calculators kids these days smh

[half tulip]

Ok i'll buy one...

[thin panther]

i mean i learned matrices while breakdancing on the ceiling

[dark crow]

Clculator??

[half tulip]

I don't understand Vector math concept at all

[odd ember]

#neverforget #career-chat message

[dark crow]

Fancy lines

[mild pine]

Hmm, Im getting nothing returned, do I need to be in standalone? Watching some tuts and talks about profiling atm

[faint pasture]

@mild pineSo do you get chugga chugga between death and respawn?

[thin panther]

vectors are just essentially directions

[odd ember]

it should work in PIE. are you sure you typed the command correctly?

[thin panther]

multiply your direction with speed, you get movement

[odd ember]

https://docs.unrealengine.com/4.27/en-US/TestingAndOptimization/PerformanceAndProfiling/StatCommands/

[mild pine]

The chugga chugga happens right when respawn occurs

[half tulip]

blueprint is all about Vector math?

[thin panther]

dot product can be used to see if 2 vectors are perpendicular, or can be reshuffled to get the angle between 2 vectors

[half tulip]

Any other type of math used in blueprint

[thin panther]

cross product gives you the normal vector

[odd ember]

discrete maths... but we don't talk about those

(we're trying to give them their privacy)

[faint pasture]

Why are you multicasting Death?

[mild pine]

Oh wait, i was typing uobject, not uobjects

[thin panther]

very important to remember

[faint pasture]

If the actual pawn is destroyed, respawn should be handled by the Gamemode. A pawn shouldn't respawn itself

[mild pine]

the BP is murdering me 😉

[thin panther]

you dont give em their privacy and before you know it your doing calculus down the back alley of tesco

[odd ember]

looks like your gun is killing you

quite literally

[thin panther]

smh just turn it around

[mild pine]

Hmm yeah, good question. Let me check why I did that

[half tulip]

Why call is visual scripting if it's math based, may as well call it Vector Math based Scripting...

[faint pasture]

Psst..... you lookin' for some limits? I got some double integrals too, good shit.

[odd ember]

it's not math based lmao. it's logic based.

[faint pasture]

K the schtick is old now

[odd ember]

math is just the arithmetic used for the logic to succeed

if you want true math based stuff, look at HLSL in teh material graph

[thin panther]

you got any of them... 23 bit mantissa's

[half tulip]

can't we use another concept for the logic to succeed

[odd ember]

and wrap your head around how to do boolean logic with numbers only

[faint pasture]

1 x 0 = 0

[thin panther]

1 x 1 = 1

there we go boolean done

1 x 2 = 2 if you like tribits or smthn

[odd ember]

now consider the math is executed every frame

and has to be valid when executed every frame

[thin panther]

just doOnce() lmao

checkmate

[odd ember]

DoOnce doesn't exist in HLSL 😔

[faint pasture]

I hope UE5 has DoTwice()

[odd ember]

well there's DoN

[half tulip]

the universe is built on Maths

[thin panther]

not very high level of it then is it smh

[half tulip]

I just realized this

[thin panther]

pretty sure its space goo

[odd ember]

are you still with us Evan

[faint pasture]

https://tenor.com/view/mind-blown-amazed-explosion-space-omg-gif-10279314

[odd ember]

or are you too high to communicate

[thin panther]

he went a while ago

[faint pasture]

BRIT DETECTED

[thin panther]

hes absolutely blazed

found the calculus i left behind tesco

poor guy

great now i wanna replay fo3

[odd ember]

maybe I should print out the blueprint APi as a book and sell it at a premium 🤔

[faint pasture]

3 was ass, NV is where it's at

[thin panther]

your sole customer is evan

save his printer

[half tulip]

But riddle me this... if the Universe is built on Math. Where did Math originate from?

[odd ember]

I dunno. if one fool falls into the trap, others can't be far behind 🤔

[thin panther]

i play em both at the same time

this post was made by TTW gang

[thin panther]

Time turtles

[mild pine]

https://gyazo.com/24c7e5c5324056c85d9aefe9be9590d7 - showcasing the issue 🤦

[faint pasture]

How far down do they go?

[half tulip]

What came first the chicken or the math?

[thin panther]

probably at least 3

[thin panther]

gabe newell

[mild pine]

But yeah, I removed the multicast. Didnt cut on the performance though hehe. Event AnyDamage is only run on the server anyways right, so theres actually no need to run the death event on server? @faint pasture

[faint pasture]

@mild pineBruh your FPS goes UP when they're dead

wtf are you doin on tick my man

[odd ember]

make it a feature to show that senseless violence is not the right way. that's a good message for a game

[thin panther]

death stranding 2?

[half tulip]

only genius know cpp

that's what I come to realize

[thin panther]

why thank you

[faint pasture]

The world's second Strand-type game

[odd ember]

lmao

[thin panther]

puttin that one on my cv

"Certified genius as confirmed by EvanX"

[faint pasture]

Evan who's your weed man

[thin panther]

yeah hook a brother up

[odd ember]

the gun sights. literally seen it when they did the state UObjects screenshot

[mild pine]

If only we could make people lag in real life 😅

[thin panther]

have you ever seen the vids of birds being stationary in flight,

same thing rlly

[faint pasture]

@mild pineCan you put your entire character and gun BP on this?
https://blueprintue.com/

[odd ember]

bird are real now?

[thin panther]

nah

thats why its in a video

[faint pasture]

It's a conspiracy by the mudmen

[thin panther]

video = electricity

bird = in video

bird = electricity

[mild pine]

The character BP is built upon an Epic asset, so not sure if thats okay 😅 But I will check out the Event Tick for sure
The asset didnt come with respawning or death as a part of it, starting to understand why 🤔 😆

[odd ember]

infallible logic

[faint pasture]

If it's from anything on the epic store that you didn't buy it's fine lol

[odd ember]

it's the gun. check the gun

[faint pasture]

they're totally open

Trust me nobody's gonna copy a 30ms BP

[thin panther]

does this mean bird && video && computer == 1

[half tulip]

I will cry myself to sleep wishing I knew what I was doing with blueprints Blueprint API Reference we are at war...

[mild pine]

Seen birds fly backwards, now that's a good watch

[faint pasture]

Did you just reinvent quaternions?

[thin panther]

birds are weird

[thin panther]

that word scares me

[mild pine]

Its purchased 😛 But yeah, I'll check the gun

The gun is doing spread on tick

[odd ember]

how do you feel about the yang mills existence and mass gap then?

[faint pasture]

Wait till you find out about Octonians

[half tulip]

When I mastered blueprints I will be so proud that I will buy myself a badge that says "Game Developer" and wear it

[thin panther]

ive never irrationally hated Euler more

[thin panther]

AAAAAAAAAA

[faint pasture]

quats are just an extension of complex numbers that happen to have properties really nice for rotations. If anyone tells you they can intuit about them though they're full of it.

[thin panther]

quaternions are my topic next year and it terrifies me

the diagram is scary

[odd ember]

only reason complex numbers give rotation anyway is because of the property of i being converted through square roots. it's all fake

[faint pasture]

i don't believe it

[half tulip]

I want my game to have a DRM

[thin panther]

what about a DMR

or a DNR

[mild pine]

The gun is setting a spread per tick.
It feels like when the character is killed that some parts of the character is not properly terminated, i.e maybe the gun? 🤔

[odd ember]

makes sense. the gun is a separate actor. you're not killing it manually are you?

[half tulip]

I'll build the DRM logic into my game

[faint pasture]

That shouldn't cost anything

Just show the full tick for both actors

something is costing a ton

[mild pine]

Its being destroyed in the right section there

[thin panther]

lemme know how fast someone cracks it plz

put it on speedrun.com

[odd ember]

perhaps they aren't?

[faint pasture]

@mild pineShow the tick. Your whole setup is like 30ms, I don't think death has anything to do with it

[mild pine]

Well visually I see them disappear, but who knows, maybe Im actually just spawning thousands of them under the ground 😆

[half tulip]

it will be uncrackable

[thin panther]

well still keep me informed

just dont lose the timer

that would be sad

[mild pine]

Ops, wrong

[faint pasture]

The ramblings of a madman ARE a tough nut to crack

[half tulip]

can i implement a DRM using a 100% blueprint project?

(please tell me yes)

[thin panther]

if youre being serious its a pointless effort, otherwise its only applicable in F# unfortunately

[odd ember]

did you make that gun or did you buy an asset?

[mild pine]

This is the only section of the character thats running on tick:

[thin panther]

the easiest drm you could do is probs steamwork api

[faint pasture]

None of that looks expensive. You can just Get Delta Seconds though, no need to have float spaghetti all over the place.

[mild pine]

Its an asset

[thin panther]

but that is stinky online only game business

[odd ember]

okay it's pretty terribly done

[mild pine]

True, everything thats on tick there is from the asset itself

[half tulip]

if someone can't afford internet connection they can't afford my game tbh

[faint pasture]

Is that like 20 child actor components I spy?

The only uncrackable game is an unreleased one. Q.E.D.

[mild pine]

Yeah, master component. Could that be the issue?

[odd ember]

20 child actor components?

[thin panther]

why dont you also add $200 microtransactions to prove your game is truly upper class

[odd ember]

...20

[mild pine]

They should be destroyed when I destroy the actor though?

[faint pasture]

IDK, doubt it. You need to do a profiling run and open it in the actual profiler

[odd ember]

child actor

components

[thin panther]

CE has been triggered

take cover theyre gonna blow

[half tulip]

Maybe I'll just release my game for a $30 price tag to give it the "perception" of being upperclass? 😉

[odd ember]

@mild pinedon't use child actor components

[thin panther]

30 dollars would get you a nice upper class platformer

[odd ember]

almost guaranteed to fix your performance issue

[faint pasture]

@mild pinehttps://docs.unrealengine.com/4.26/en-US/TestingAndOptimization/PerformanceAndProfiling/Profiler/
https://docs.unrealengine.com/4.26/en-US/TestingAndOptimization/PerformanceAndProfiling/StatCommands/

stat startfile to start recording, stat stopfile to stop

[mild pine]

Hmm, how would I go about setting up a modular character then? Compile the whole thing into a combined mesh with some magical code? 🤤

[faint pasture]

then open in profiler

and figure out wtf is so expensive

[odd ember]

you attach actor to actor like a decent human bean

child actor components are performance hogs

and come with massive issues

[mild pine]

Are all assetpacks doing a bad practice or what? 😆 This is like the third character pack I have that uses that method haha. I'll remove them and test out! 😛

[mild pine]

Gotcha!

Thanks for the assistance guys! 🙏

[odd ember]

I would never ever trust an asset pack with BP code

that's a recipe for failure

[faint pasture]

I did that when prototyping my FOV system and found out that the math was taking everything up. Moved just some math to C++ and went from 8ms to 0.04

[small halo]

right now this is working and the dragon is going to the location. But i am struggling with setting its rotation to the point he is going to

[faint pasture]

Just turn on "Orient Rotation to Movement" or whatever in the CMC

[odd ember]

rotation = (new location - current location).normalized

[small halo]

i have it on

[faint pasture]

Does he look at his destination while moving?

[small halo]

no he is just still

[faint pasture]

Is he moving?

[small halo]

yeah he is moving to the location

but always looking forward

[faint pasture]

Wait a second

you're manually moving it, NOT using the CMC?

[thin panther]

this sounds like something that could maybe benefit from a behaviour tree

[faint pasture]

Any particular reason why?

he doesn't need a behavior tree, he's moving it manually but has a CMC which makes zero sense.

[thin panther]

bevaiour trees make ai nice and clean

[thin panther]

ik im just saying if the dragon gets more functionality then it would be nice

[mild pine]

Okay, frames actually went up by 20 when I got rid of the 20 child actors, but the respawning issue is still there. Will profile 🙏

[faint pasture]

There should be some node called AI Move To or Simple Move To, just call that when you pick a new spot

you already have a movement component, you do NOT need to be moving him manually

[small halo]

struggled with bt as eu4 doesnt have a 3d nav

[odd ember]

20 frames difference lmao

[faint pasture]

OK so it's in 3d, is it actually or is he hovering?

[small halo]

can u further elaborate on this pls

https://gyazo.com/3ab43535ba114b99c2285893925fbf1d

[faint pasture]

Your dragon has a character movement component

you're not using it

you're manually setting position on a timer

[small halo]

first time doing a flyable object so it was very confusing

[faint pasture]

Start with calling Add Movement Input on tick and see where that gets you

[snow jolt]

is there a way to know how many of a certain class i have spawned (to limite the number of enemies)

[faint pasture]

You could get actors of class and get the length of that array but why not keep track in the spawner?

[odd ember]

yeah you'd usually want a manager class that spawns your enemies and keeps track of them

but sure get all actors of class on tick will work too

[faint pasture]

Does that crawl ALL the actors in the world or is there some sort of registry or map?

[small halo]

like that?

[half tulip]

Hi Gurus... ELI5: What's a "Transform" ?

[odd ember]

it's not as bad as people think, but not cheap enough that you want it running on tick

[faint pasture]

@small haloSubtract your position and normalize it

[odd ember]

it's still some O(n^3) in performance

[faint pasture]

you want the direction TO the target point from where you are

and that will aim at a different target point every frame. Might be a little spastic lmao

[half tulip]

Explain Like I'm 5: What's a Transform in relation to blueprints?

[faint pasture]

It's a position + rotation + scale

position rotation and scale all rolled up into one

break it, and you get the 3 components

break those, and you get THEIR 3 components

[half tulip]

is there a node for just position + rotation ?

[faint pasture]

Nah, just make a transform with scale 1,1,1

[half tulip]

why that numbers

[faint pasture]

that's a scale of 1, the default

if you put bigger numbers, you'd make the thing bigger

smaller numbers, smaller

[small halo]

what am i subtracting the dragons position from

[faint pasture]

0,0,0, it goes poof

[thin panther]

indeed

[half tulip]

oh i see

[faint pasture]

Target position

[half tulip]

it's for a checkpoint system for a character

so I assume scale wouldn't be needed

[small halo]

https://gyazo.com/8a466d2208da8d68c59bf41a2a153de4

like so?

[thin panther]

i eman checkpoints you could just use savegame to save and load character position

[faint pasture]

@small haloSwap them

that'll make you fly away from the target

[small halo]

what should the tolerance be

[faint pasture]

Whatever you want, probably pretty big for a dragon

oh wait for the normalize

leave it

normalize just turns 100,0,0 into 1,0,0

normalize makes a vector of length 1

[half tulip]

save/load system is not implemented yet

[small halo]

uhmm

the dragon is infinitely going up

[mild pine]

Whew, what am I even looking at 🤯

[odd ember]

ship it

[thin panther]

its like a 2 min job for checkpoints, would be better to do now rather than later

[half tulip]

implementing a save system is not a 2min job lol

[thin panther]

for just saving and loading player loc it is

just create savegame object

handy dandy bp class

[faint pasture]

start in gamethread

[odd ember]

some terrible netcode, apparently

[faint pasture]

Show what you have

[small halo]

https://gyazo.com/952c1abf97aaedce8dc06db6c290f6ed

just this

scrapped the other code

[faint pasture]

@small haloJust have him aim at one for now

that'll change targets every frame which is prolly not what you want

[half tulip]

dude this is not a 2 min job it could take me a week to implement this into my game: https://www.unrealengine.com/marketplace/en-US/product/easy-multi-save

[thin panther]

nah you dont need that

[half tulip]

I do

[thin panther]

just use the savegame class built in

[odd ember]

imagine paying for blueprint assets

[small halo]

dies of cringe

https://gyazo.com/6dab58ca942182e288bbc53f1b1f6b8a

[half tulip]

not everyone is a BLUEPRINT GURU

that mastered blueprint and learned the API library

[thin panther]

hes onto us, quick hide the api reference

[half tulip]

p.s don't hate on the marketplace

[faint pasture]

@small haloDo this for now, does he fly at point 1?

[half tulip]

it gives us the non-guru noobs HOPE

or should they just call us script kids?

[brazen pike]

It's also a time saving thing. Some people would rather spend time on evironments or weapons than making a complex weather and lighting system. So they pay $20 and buy one to save a week researching how to do it and writing it

[faint pasture]

You won't really be able to tell what marketplace assets are worth it until you don't really need them.

[small halo]

nah he doesnt

[snow jolt]

ok thank ill do that

[faint pasture]

Although I do use some stuff like LE Standard Library etc cuz aint nobody got time for dat

[thin panther]

but the point is for a checkpoint based game the system takes a few mins to implement

[small halo]

https://gyazo.com/02e30b144027f50d41fe3f92e115f180

literally thats all i have

[thin panther]

no one is saying marketplace doesnt have its uses

[small halo]

hes not even going to the point

[faint pasture]

Where's he going? Do you still have your old timer setup that is setting position?

[odd ember]

the most I'd buy from the marketplace would probably be animations

[faint pasture]

But they don't match MY skeleton

I'd buy sounds maybe

[odd ember]

retarget

[faint pasture]

if I can get raw wavs

[odd ember]

nah I'd get a sound designer

[half tulip]

@odd ember You're on the naughty step for insulting our most cherished marketplace

[odd ember]

it's not expensive to get something like that commissioned

[faint pasture]

I have all the gear to do that but I'm not about to set up a mic and clop around like an idiot

[small halo]

no, all the other code is unlinked. He is just doing 360s and flying up

[faint pasture]

Although I do have to record some exhaust system impulse responses. That'll be fun

[small halo]

like this

[half tulip]

I don't think many indie games would even be released without help of blueprint assets

[odd ember]

sure, just not other people's blueprint assets 😂

I'll use my own

[faint pasture]

Meshes and materials maybe. I'd never use asset BPs tho

[half tulip]

there would be 75% less UE4 indie games released without blueprint assets

[thin panther]

you see im big brain, instead of buying a £50 gun sound pack, imma spend £90 getting my firearms certificate, a further £200 for a safe, a further £2000 for ammo and guns, and a further £500 for recording setup

then remember i cant do audio

[odd ember]

instead of chancing finding a marketplace asset using 20 child actors

[thin panther]

thats perfectly reasonable

[faint pasture]

Sir I live in America, I'll just go get a gun from the corner store and record it on my phone

[thin panther]

is what id say if i was dumb

[odd ember]

#blueprint message

@small haloCan you DM real quick for a stream?

[small halo]

yeah

[half tulip]

the isle of the unreal marketplace is as familiar to me as my local supermarket

[thin panther]

now youre just making sense and thats not ok

[thin panther]

good luck finding soup there smh

[half tulip]

my diet is mainly ramen as most of my income is spent on assets...

[odd ember]

😂

maybe I should setup a side hustle making shoddy blueprint assets

sell them at a premium

throw in a link to the blueprint API as a bonus

[brazen pike]

$50 "Advanced Gunfire System" just a linetrace

[half tulip]

I've actually bought one of those before 😆 literally just a linetrace

[odd ember]

plus one or two arbitrarily placed child actor components

[half tulip]

and a gun that looks like a turd

with a really shoddy animation

Do you know picking good marketplace assets is an art of itself?

[trim matrix]

Any reason why the print is not printed in the event above?

[sinful ingot]

I'm probably doing something dumb, but I have a BP with Instance Editable variables. Several instances of this BP exist in a parent BP. I simply can't find where to edit those instance variables on of the child BPs. The when I click on each instance in Parent BP Viewport it only points out what class the child BP is.

[odd ember]

either the cast fails, the game mode doesn't exist, or the execution beyond the screenshot never happens

[trim matrix]

the cast works because the actor destroy is called

the gamemode does exist because its able to print the values from it somehow

like the enemies remaining one

wish i could record

[odd ember]

use breakpoints

see what happens

[trim matrix]

alr

well idk if these help, but these are the errors that are displayed

oh

maybe it doesnt exist?

weird

[odd ember]

the game mode isn't set

so of course it isn't going to be called

[trim matrix]

oh

its set correctly

ah the weirdest errors

[odd ember]

that's not where you set the variable. the variable has to be set independently. it doesn't matter what your project settings are. that only matters for which game mode is active

you can try using the GetGameMode node instead, and cast it to your game mode type

[trim matrix]

oh wait

lemme convert this file

[trim matrix]

Basically why do the newly spawned charcters not come torward me?

The node is properly setup so its able to achieve it

[surreal peak]

Is the one that does run towards you placed into the level?

@trim matrix

[visual vigil]

Guys is BP packaged in to PAK ??

[trim matrix]

yes

the ohters arent, im trying to make the others run torwards me also

im using the spawn actors stuff to do this btw

[bright frigate]

papisssss what are your suggestions on setting up a true first person camera? Use the third person mannequin and modify that? Or use the first person and do stuff there? Are there any more "less hacky" ways? I've been spending lots of time looking for and reading on stuff online but these are the two most popular but both of them are rather hacky

[last abyss]

in the details panel on the right, there's an option for 'Auto Possess AI'. Make sure its set to Placed or Spawned in world.

[plain jay]

Is anyone here familiar with apply skin weight profile? Im working on a dismemberment system and I wish to remove the influence of the detached limb from the character, is this something that can be done with skin weight profiles?

Simple Wheeled Vehicle Movement Component any idea why i cant find this component under Pawn class?

[dreamy yacht]

Hi, could someone help me? I am following this vehicle tutorial since beginning ( 5 parts so far ), but I am stuck A.F. at 1:59 and then at 3:47 when I try to set MAX LAPS

https://www.youtube.com/watch?v=trdAsxgSGJY&list=PLZlv_N0_O1gYdhCvvMKGpCF6LCgBz9XeS&index=5

[maiden wadi]

What do you mean by under pawn? Are you looking in a pawn's Component list?

[dreamy yacht]

it show up set max laps no matter what I do

And in my case the default player controller is PlayerController, not the MyPlayerController ( 4.27.2 )

please help

I am totally stuck

[echo salmon]

@maiden wadi yes

[maiden wadi]

What engine version? I can see it fine on 4.27.2

[dreamy yacht]

4.27.2

[maiden wadi]

Was asking Clickys.

[dreamy yacht]

ok

[maiden wadi]

But what code do you have that is setting your UI?

[echo salmon]

@maiden wadi 5 version

[maiden wadi]

No idea then. May be removed, may be in a plugin. May be just messed up.

[echo salmon]

I got a ready assets from synty store , specifically a car. And iam trying to move the car with spline , but the wheels are not rotating . And iam trying to figure out how to rotate the wheels when the car move .

[dreamy yacht]

hey there, can someone help me?

moreover, when I look into the video at 3:31 I see, that the Controller Reference he created is of array type

mine is of controller type or smth

[maiden wadi]

What code do you have that is setting your UI?

[dreamy yacht]

Could you clarify ?

[maiden wadi]

You have a widget somewhere that is displaying the lap count?

[faint pasture]

This is exactly why following tutorials is a bad idea. The second you're not quite sure exactly what you're doing and why, you should stop and review. You're way ahead of yourself right now.

[dreamy yacht]

nope

not yet

[dreamy yacht]

You have a widget somewhere that is displaying the lap count? The lap count is based on the amount of checkpoints cleared by pawn actor ( in this case a vehicle )

it will be done in the last video from this series or so

[maiden wadi]

Then where is it always showing the max lap count?

[dreamy yacht]

the code for it is not ready yet

the variable is done

but the full code is a result of full series of tutorials from Time Attack Racer

this is not the issue, from what I think

the problem is - the engine has problems to cast to player controller

what may be the cause ?

1:59 of video

[maiden wadi]

Ah. You didn't promote the variable of the correct type I'm assuming.

You can't get this, right?

[dreamy yacht]

yes

[maiden wadi]

You have to follow exactly what he does at 1:59. You have the wrong controller type as your variable.

[dreamy yacht]

I' ve tried

from what I've seen in the next video, he has a PlayerController in his project inside the blueprints folder

https://youtu.be/gp92v_iVGSQ?list=PLZlv_N0_O1gYdhCvvMKGpCF6LCgBz9XeS&t=78

there is no PlayerController file in my project

[faint pasture]

Or just put the project down and do something small until you know wtf you're doing. This is like following along with a surgery tutorial but you keep reaching for chainsaws and wondering why it's not working. Get the knowledge to even notice where the mistakes are first before going in the deep end.

[maiden wadi]

Realistically, I hate saving refs in classes for things that you can get globally. I think the idea is incredibly stupid and just creates unnecessary upkeep. Framework GetWorld getters are not expensive.

[faint pasture]

I thought I looked at it once and it was like O(n). For get actor of class anyway. All actors might be a bit spendier

[maiden wadi]

"Why is my widget getting the wrong pawn's health? 😮 It shows fine until I respawn"

[obtuse bronze]

How can I change the camera's position values like xyz without the engine resetting its values? Thanks

[icy dragon]

[context needed]

[obtuse bronze]

Okay, the camera I am referring to is the SideViewCamera which is created when creating the side view scroller project in UE4, I just want to be able to change one of the transform values x y or z using blueprints, the issue is that the camera gets reset to the player every frame by the looks of it and so is there any way I could decouple the camera from the player so the camera stops resetting itself to where the player's position is?

It's attached by default when creating the project

"is there any way I could decouple the camera from the player so the camera stops resetting itself to where the player's position is?"

I don't know how to hence why I'm asking 🙃

[dry laurel]

1. Can I iterate over all children of a gameplay tag in BPs? E.g. select Stat and iterate over all stats.
2. Create tag from FName without exposing FGameplayTag::RequestGamplayTag myself?

[maiden wadi]

I believe no in both of those cases. Only 50% on the first one. 100% on the second. Normally if you need that you'd just drop them into a container.

[dry laurel]

Thanks

[steel sequoia]

why can a delete save game fail?

like what causes might there be?

[stuck folio]

Hey guys. Needed a small help. I have a main menu widget, main level and a gameplay level.
Game start with the main level with main menu widget in front of the player. and once we click play, the gameplay level should open.
I have posted the main menu widget.
When I just have a remove from parent node, the menu disappears and black screeen (Main level)
But if I further connect the open level node after the remove from parent node, the main menu doesn't go away. but the gameplay level starts in the background of the widget

[steel sequoia]

i just open the new level @stuck folio because the widget will be on the old leve lanyway

[maiden wadi]

Most likely the save system isn't valid(not likely in blueprint) or the name isn't valid.

[steel sequoia]

level anyway*

thanks @maiden wadi

how would i fix it just being not valid?

[maiden wadi]

Check DoesSaveGameExist usually first.

[steel sequoia]

thanks

i run that on level open

then when you use the save station it opens a new level and transfers your stuff with you

but i want it so if you die you wont keep your stuff a second time

although i think ive found a work a round 🙂

[stuck folio]

I tried that, no difference

[earnest tangle]

I duplicated one of my test levels and a level script actor BP asset appeared in my content browser, should I be worried something broke lol

I've never seen this happen before...

[austere ingot]

ive got a blueprint that will attach an object to a hit result from a line trace. works great for floors and ceilings, but can't figure out how to get the correct rotation when attaching it to a wall

impact normal?

[earnest tangle]

normal should give you the wall's facing that was hit yeah

[quartz fossil]

Not sure if there's a proper place to ask about this, but, I noticed that when you package a game, the game automatically gets the native culture of the machine and switches the language in particular. Is there any way to prevent this?

At least when using the built-in system Unreal offers

[austere ingot]

what is the math for taking a normal from a hit result and creating a rotation so something will match the angle of the wall it hit?

[quartz fossil]

From blueprints? You probably just want to take Rotation From X or From XY, depending on what you want to do

[lilac rock]

helllppppppppppppp

does anyone know any good tutorials on aim offset that DON'T use blendspaces

[odd ember]

angle between hit and wall?

[austere ingot]

not really I guess. just trying to correctly rotate a mesh that normally lays flat to sit correctly on the wall

its almost working, but everything is upside down on the walls

haha

[unreal wing]

Hey guys! I hope someone can help me with this problem. Currently I have the player walking into a box trigger which will change the the players camera to the fixed camera on screen. However, when I collect the coins the camera resets the the players and then reset to the fixed camera. I can send in a video if it helps, im guessing it might be a problem with the overlapping maybe. Any ideas?

[jaunty summit]

the camera resets the the players
What do you mean by this?

[unreal wing]

I actually figured it out, I was originally using a player reference to call the trigger, but I have to use a pure cast. It works now, but honestly im not sure why it needs a pure cast

[odd ember]

this smells really bad, show your code

[austere ingot]

still struggle boating on trying to rotate an object when placing it on a wall. i have a torch that stands up straight on the ground, and if I want it to just stick directly out of the wall, as if it was still standing straight but off the wall, how do I do that? all of the 'Make Rot from X/Y/Z" have it aligned different, but none are correct at facing the bottom of the object towards the ground. all of tham would work if I could rotate it 90 degrees on one axes

This worked

[frail meadow]

hi 🙂 I'm working on nametags in my game and i have it setup but the widget component is set to screen space but i want it not to resize once players are too far away
but i cant find it anywhere

[maiden wadi]

Another reason why widget components are terrible.

[frail meadow]

ok but how do i this

[maiden wadi]

Generally speaking, when you get to a point where you need moving widgets on screen for your gameplay objects, a manager that ticks them on screen space is much better. Widget components are extremely limited outside of creating actual 3D UI like holographic displays and such.

[silk roost]

is making dark messiah spikes even possible in ue4?
https://thumbs.gfycat.com/CleanZigzagBluebottlejellyfish-mobile.mp4

[tidal marlin]

What was the name of the plugin that removes unused assets when bundling?

[maiden wadi]

@tidal marlin Unreferenced things shouldn't be cooked usually.

[maiden wadi]

Can it be done with 1s and 0s?

[silk roost]

idk what you mean by 1s or 0s

[small halo]

https://gyazo.com/6fe84dcd5a500be9753e264d52382ecb

try to make the fireball go to the players position

but its not working xD

[maiden wadi]

Computer processing is done in 1s and 0s. I was being a smartass. You can do anything you want to in Unreal if it can be programmed. Meaning that yes, you could do that spike effect in Unreal. Very easily in fact. There is a node named LaunchCharacter or something for characters. If your AI are characters, you can kick them backwards with this. If they fly into the spikes during this time, splat.

[maiden wadi]

Fireball have a ProjectileMovementComponent?

[small halo]

yeah the fireball is working

just going to the wrong place

[silk roost]

Problem is with spikes that penetrates enemies and still there is physical body simulation

[small halo]

i want it to hit where the player is

[maiden wadi]

You call SimulatePhysics on the skeletal mesh when they die with some constraints. Or hard code an animation.

[maiden wadi]

As in Follow, or just initially shoot towards the player?

[small halo]

just initial shot

doesnt need to follow the player

[maiden wadi]

Your look at rotation doesn't work when used on Rotation of the actor spawn?

[small halo]

no it didnt work unfortunately

[maiden wadi]

It should. How is your PMC set up on the fireball? It shouldn't be anything but an initial velocity in the X direction.

[small halo]

https://gyazo.com/7da2b3042ab45ec9b6f166601afa3f34

its going near the player

not on the player

[maiden wadi]

What all have you done to the PMC?

[small halo]

https://gyazo.com/0cd1128a3dab2fccdab0a3ae4de9bae2

just that and changed the initial speed and max speed to 2000

[maiden wadi]

Oh. I think I see your issue. Had to watch the video a couple times.

For your LookAtRotation, use the spawning location, not the dragon's location.

Also for an easier lifetime, all actors can simply call SetLifetime and will destroy themselves after that time. Useful for projectiles.

[small halo]

so the initial point the dragon spawns at?

[maiden wadi]

No, The same thing you're plugging into Spawn Fireball Location.

You're discerning the fireball's trajectory based on the dragon's location, which is way off from where the fireball spawns. Need to start the FindLookAtRotation from the same place the fireball will spawn.

[small halo]

https://gyazo.com/01b662580327aa91952c0ee12b92abf1

the ball is still not hitting the player

its closer now but not exactly on the player

[maiden wadi]

Is it aiming at the player now though, and just falling short of hitting them?

Your directional aim should now be correct, no more left/right issues. Gravity is still an issue regarding that though.

[small halo]

oh i see

i turned off gravity and now it works!

thanks

[cobalt gulch]

does anyone have a generic ue project where a character with the ue4 rig is holding a gun in first person?

[silk roost]

why you just don't create new project from launcher ?

[cobalt gulch]

because the rig doesn't have a body

[thin panther]

There is a free anim pack that contains third person weapon anims

[cobalt gulch]

do i just place this over the first person character?

[thin panther]

No cause the first person character doesnt have a body

Youll need to set it up yourself

Shouldnt be thaaat bad

[dreamy yacht]

Actually I think, that most of our UE4 knowledge is being gained through tutorials. Maybe I am too stupid to finish such tutorial, or not.

Actually I've managed to fix the problem - there were two ways for it - I could just simply cast to player controller directly ( you could just told me that, what would save me lot's of time ) , but I've also went back to episode 2 of series, which I somehow partially skipped, where the epic guy set all those variables and the demanded MyPlayerController

I've done it and here's the proof

[odd ember]

speak for yourself

[silk roost]

I think most ue4 knowlege is gained by doing stuffs, even if you make new project but every time you doing something now and experiment you will know some stuff eventually

[bright harbor]

i still need help on this if anyone has any ideas, i've tried checking if the player is closer to the end or the beginning of the spline, but that didn't work out super well, mainly because that takes nothing about where the player is facing into account

[odd ember]

base it on the dot product between the character's forward direction and the nearest spline point direction

[cobalt gulch]

Is anyone able to help with the project? I can stream it

[bright harbor]

a value of greater than 0 would be forward and below would be backward?

[odd ember]

correct

[fair magnet]

does this include double character's and white spaces?

[odd ember]

why not test it and find out?

[onyx token]

say @odd ember - could it be that the animation thread runs on a different tickrate than the game thread?

I've got some code that gives out a float in my character blueprint - and i wanna use that float in my animation blueprint to manipulate rotation values in my skeleton-

And it's all jittery as if there were half-frames or something missing
https://cdn.discordapp.com/attachments/847253861403197471/960216845074448434/UE4Editor_38tvvtgjzP.mp4

[odd ember]

show code

[onyx token]

hang on, lemme clean it

[odd ember]

and yes, threads generally are asynchronous

[onyx token]

do comments work on blueprintue.com?

[odd ember]

no idea

again, test it

[onyx token]

ye

[thin panther]

Theres plenty of guides on how to get a full body to hold a gun

[cobalt gulch]

could you link a simple guide which would work in multiplayer pls

[onyx token]

here it is, bone rotation code in my character BP
https://blueprintue.com/blueprint/kzkgd8qq/

also comments work, which is neat

[odd ember]

wait

you do this in BP

to use in the anim thread?

[onyx token]

yes

[odd ember]

yeah don't

use the animBP

[onyx token]

but why?

[odd ember]

at most

because it's running on the game thread

[onyx token]

ok wait, but i wanna use the animBP on both the player, and NPCs

and this code wouldn't really make sense on NPCs since they have no camera

[odd ember]

that's fine

then just don't use it for NPCs

we've been over this before

[onyx token]

you mean with a branch that says "only if it's the player" ?

[odd ember]

you also shouldn't base something on whether it has camera or not

that's a recipe for disaster

start over with this, and think about the architecture first

inheritance here is important

you can solve it in different ways

but if you're doing something that affects animations, it should stay within the animBP so it executes on the anim thread

[onyx token]

hm i see... i misunderstood then

so it's okay to put stuff like this into an anim blueprint that i will use for multiple things?

[thin panther]

You can find one very easily

[odd ember]

use TryGetPawnOwner once on beginplay

save it as a variable

post cast

[onyx token]

ok sure, i did that, i was just making sure it's clear what i'm doing, otherwise if it was a random variable it might not be 100% clear

i see, but the overall thing is okay... Thanks!

--
Also more general question-
I renamed the default ThirdPersonCharacter into "PlayerCharacter"

But this for some reason still spits out "ThirdPersonCharacter"

but when i try to make an if statement-
I can only select player character - the thirdpersoncharacter gets displayed as a redirector

[cobalt gulch]

could you link a simple guide which would work in multiplayer pls @thin panther

[grand valve]

find the redirector in the folder, right click on it, fix up redirector

[thin panther]

No

[wicked osprey]

guys, how to make it so that the first time you start the game, the sound is immediately loaded?

[thin panther]

Also dont focus on multiplayer if youre new

[cobalt gulch]

I need to for my game, basically I just need it so the character will work in multiplayer sessions, yeah im going to work on simple stuff but i need it so that it works properly if that makes sense lol

[thin panther]

Work on simple things first

Multiplayer is a complex can of worms

Think about multiplayer when you have more experience

[odd ember]

use casts...

[onyx token]

i did

[odd ember]

then if it passes the cast you're good

no need to validate extra

just save it into a variable

[onyx token]

wait wut

i'm confused now

[odd ember]

if the cast succeeds

[onyx token]

I cast once on begin play
And save whatever this spits out, as a variable

[odd ember]

yes

[onyx token]

so if whatever it spits out - happens to be the player - i want extra code to run

if it's something else - don't run the code

[odd ember]

potentially yes. but equally you may want to create a subclass of animBP for players exclusively

[onyx token]

awww i wanted to have 1 animBP class for all characters period

that way i wouldn't have to make stuff twice

[odd ember]

do you also just have one class for all your characters?

you don't

that's the whole point

[onyx token]

i have 1 parent class

and child classes

[odd ember]

inheritance means you never copy code

[onyx token]

oooh you mean i should have a parent and child animBP class

[odd ember]

sub class

and super class

yes

parent/child is a misnomer because unreal uses that terminology for other things too

super/sub prevents language mixups

[onyx token]

ok so this should be called super/sub

[odd ember]

yes

[onyx token]

i see... thanks!

[odd ember]

super is the "parent" class

sub is the "child" class

as it were

[onyx token]

Alright... So i'll make a CharacterSuperClass
And a bunch of CharacterSubClasses

[odd ember]

sure but you only need like 2 animBPs now

[onyx token]

sure, because i only have a player, and a humanoid NPC

[odd ember]

you may need more if you deal with different skeletons

[grand valve]

Doesnt overriding the parent AnimBP in Blueprint effectively stop you from editing the child blueprints animation graph except for the individual anim overrides?

I had the issue before when i would make parents and childs but i wanted some slightly different state logic for the child...

[onyx token]

i wish this server had like a karma feature... you're being so helpful!

[odd ember]

well you only want to change the logic for the animation in the super class anyway

but you can change the bp logic in the subclass

that's kind of the tradeoff

it's not perfectly oop

or there'd be a looser coupling between animation states and BP

[grand valve]

right, i got a bit tripped up on this before and tried using linked anim layers and stuff to make it a bit more modular.

[odd ember]

but I basically had to copy my animBP once over because I have two different humanoid skeletons

(m/f)

[grand valve]

right, so you couldnt actually share logic between the two skeletons in that case?

[odd ember]

I can share the logic, but not the animations

or well, some animations could be shared

but because of the tight coupling of the animBP between animation states and the BP part of the animBP there is no way to separate them out

so I had to copy it over

[grand valve]

yea ok just checking, had the same issue and did the same thing..

[odd ember]

if they would separate the anim states so they could hook into different animBPs that would be ideal

[grand valve]

agreed

[mighty crown]

I'm attempting to create a tornado with physics that's using the impulse code from the first person blueprint. Is there a way to debug the blueprint or view the collision events triggering in a log somewhere?

[odd ember]

breakpoints

[mighty crown]

oh I think I got it. Just enabled the debugger for the blueprint and it put me in my game. Awesome.

[random plaza]

i'm just now having my code peer reviewed by an experienced dev and im just realizing how convoluted it all is

[odd ember]

maybe I should do that as a side hustle 🤔

[gentle urchin]

Would be interesting to have it reviewed

[onyx token]

oh wait actually i figured out now why i did this instead of "on begin play"

[random plaza]

im doing it with a friend who is experienced in python, but she understands it all since it's blueprints

[onyx token]

because if i do it on begin play, every single time i test it, i end up with these stupid annoying 2 or 1 error messages

which then vanish once the variable is set

[random plaza]

why not have is valid?

[odd ember]

yeah but you dont want to do that

[onyx token]

but why?

[odd ember]

because that checks it every tick

and you don't need to do that

[onyx token]

hm. guess that's true

but the 2 error messages are still annoying tho... how can i get rid of them?

[odd ember]

the errors tell you that something is wrong

so it's more about solving the underlying problem

[random plaza]

https://docs.unrealengine.com/4.27/en-US/API/Runtime/Core/UObject/TWeakObjectPtr/IsValid/

[odd ember]

is valid doesn't solve the problem

[random plaza]

i guess

[odd ember]

it'll make the errors go away

[onyx token]

the problem is that for some reason there's 2 animation ticks before beginplay sets the variable

[odd ember]

but it doesn't make your variable save

can you try and do a test a few times with a print string in both the animBP and your character BP and see which one comes first? and if it's consistent?

on begin play for both of them*

[onyx token]

so

The character bp comes first
then the child animbp
then the super animbp

[odd ember]

then on begin play in animBP plays last, which means everything should match up

is this consistent?

[onyx token]

well my problem is that
within 1 animBP
the update plays before the beginPlay for some reason

like 1 or 2 ticks

[grand valve]

which of these 2 are you using on the anim BP?

[onyx token]

first one

ooooh

ok the second one works

[odd ember]

there's like 2 other options for this as well

in the class defaults you should be able to untick "tick before beginplay"

or some such wording

and in the character, you can manually spawn the animBP

[onyx token]

oh i see i can do that

neat!

thank you!

[odd ember]

manual spawning is especially useful to retain full control over race conditions

as one class effectively becomes the "manager" of the class it spawns

and you can always assert that the manager will spawn first

this is also possible between player controller and character as well

[mighty crown]

hmm I can't seem to get a collision event to be triggered for my tornado.

I have collision turned on/have the generate collision event in my niagara system. Not really sure what I'm missing :/ Edit:Maybe I need On Event Hit instead of on Component Hit?

I'm using the impulse code from the ball in the starter FPS project

[analog hazel]

quick question.... In character BP, The camera boom should be the child to the camera not the other way around correct?

[spark steppe]

the spring arm? should be parent of the camera

[analog hazel]

Okay, that is what i was thinking after looking at my project the spring arm is the parent of the camera half backwards lol, but when i fix it, i lose my left mouse down free camera rotation

not sure what part of the BP you would need to help figure it out if some one dont mind

[crimson jolt]

Is it possible to have two instances of the same macro execute without interfering with each other?

I have a macro that is being executed at two places (two separate macro nodes) simultaneously, but the result is essentially the same as just plugging the two execution paths into a single macro node

[analog hazel]

my zoom broke while switching those around also,

[zealous moth]

a macro is like a function with some limitations. It will do what it needs to do as a separate set of calculations independent of each other.

[slow wyvern]

Is there a way to anchor the root bones pitch (roll) while having pitch enabled in the characterBP?

[crimson jolt]

That's what I thought as well, but it's not what I'm seeing right now in my graph

[zealous moth]

show screenshot?

[zealous moth]

character movement allows you to change the rotation rate. if 0, no rotation

[crimson jolt]

I have two separate execution paths with separate macro instances. In the macro I'm doing an interpolation that is being interrupted when the macro is executed again. The problem is that, if I execute one of the paths, it interrupts the other. Very strange

[zealous moth]

erm... interpolation in a macro??????

[slow wyvern]

I have 0 for X and Y on the rotation rate of the character movement.

[zealous moth]

macros don't do time

use a function, those can use timings

[analog hazel]

@spark steppe Hey also noticed something really strange with my camera after switching the camera and spring arm parenting placement...

[crimson jolt]

Isn't it the other way around..?

[zealous moth]

nope

[slow wyvern]

The problem is due to the fact that I have use controller rotation pitch enabled (a setting I have only on, bc I want my pitch to be replicated (using rpc’s creates a greater lag)

[zealous moth]

in fact, you cannot right click to get anything timing related in macros but can in functions

[crimson jolt]

This is inside a macro

[zealous moth]

is that a new feature in ue5?

[slow wyvern]

No functions don’t allow for time stuff, macros do

[zealous moth]

in ue4 macros can't do timings

holy crap you're right

[crimson jolt]

This is in UE5, but I think the same is true for UE4

[zealous moth]

i have mixed up the 2

nah you're right

then forget my red herring

[crimson jolt]

Aight it's fine xD Well, I still don't know what's going on in my macro

[zealous moth]

what is it like inside?

[crimson jolt]

I think this is the problematic part

I don't know why but the interpolation gets interrupted when ANOTHER instance of the macro fires

Maybe it has to do with local floats? Idk

[zealous moth]

typically what happens is that you have events repeating before the other one finishes

maybe use timer or tick with boolean check to make sure it only happens once

worst case, plug a debug breakpoint?

[crimson jolt]

Well, I need two firing at the same time

[mental trellis]

Can macros have internal vars? Are you tryng to fire off 2 of the same macro in the same scope and the internal vars are being reset?

[zealous moth]

macros can't iirc.

only functions

[mental trellis]

Well, they can use the variables of the containing object then. The same issue applies.

[zealous moth]

that or i need a break

[crimson jolt]

Macros can have "anonymous" temporary variables, but you can't name them like local variables

I think the local floats are being reset or something, but they are different instances of the same macro so they should have their own set of variables right?

[earnest tangle]

^very limited tho, there's only a couple of types that are supported

[mental trellis]

A macro will run in the external scope. So if you have the same object calling the same macro from 2 different places, it will use the same variables for both

Same object could be the same function on or the same instance of an object in the instance graph

[crimson jolt]

So if I have a pawn (the object), you mean that if I call two instances of the same macro at the same time it's essentially like calling one instance twice?

[mental trellis]

Pretty much. Macros aren't functions.

All those nodes inside the macro are basically not inside your macro

[odd ember]

how are you calling this? it smells all kinds of bad

[mental trellis]

The "macro" is just a way to tidy them up a bit.

[crimson jolt]

So it's basically just a collapsed part of the graph then, alright thanks for clearing that up!
@peak wedge I have two timers, each calling its own instance of the macro

[fluid lagoon]

Is there a way to tell the cast which controller is passing through?

The hud seems to spawn for the first player, but when another controller is present, the hud doesnt appear and the cast fails

[odd ember]

are you calling the hud on the server?

because it sounds like you are

[mental trellis]

What you can do is have 2 sets of variables, one for each timer - then pass the specific variable as an input parameter to the macro (macros have that, right?)

[fluid lagoon]

Its a local multiplayer

[odd ember]

doesn't matter

hud is always client side

[fluid lagoon]

Then no I dont think so

How do I call it on the server?

[odd ember]

you don't

you are already doing it

you should be doing it on the client instead

[fluid lagoon]

Is there a guide on how to call it on the client?

[odd ember]

have you tried google?

[fluid lagoon]

Yes, but message received

[crimson jolt]

Yes, that would work. I don't like cluttering my variables field with one-time use floats tho xD Well, I'll get back to fixing this up. Thanks!

[mental trellis]

Use an array? 😛

[odd ember]

use functions instead of macros

[crimson jolt]

I do whenever possible, but for things like interpolations that's not possible

[odd ember]

well macros aren't useful for interpolations either

if it's an actor subclass you can use timelines or timers

which both allow for function use

timers even work in components

[crimson jolt]

Well what about just using them to organize the node graph?

[odd ember]

you may as well use functions

or collapse the graph

apart from loops I avoid macros like the plague

[crimson jolt]

Right, so I take it a collapsed node graph is faster than a macro then?

[odd ember]

there is no performance increase

like you're not going to game the system

this is purely from an organizational standpoint

[undone surge]

is there a way i can attach the left hand bone to a bone of a gun mesh so that it sticks there on the gun

[crimson jolt]

Then why are you so hostile to these poor macros? xD

[odd ember]

because everything they do can be done better by either functions or just properly organizing your blueprints
