better in terms of optimization. I know, micro optimizations are a one way ticket to hell

You'd need something that convert any non-numeric characters in the string to a number. You can use a free plugin like Low Entry Extended Standard that can convert strings to bytes which you can then work with.

This here is an example of a recursive function that should take a string of any length, and continually compact it by summing the values of each string character until only 4 bytes remain (the size of an int32). The array of bytes can then be used to convert to a number.

Though I wonder if you have a string long enough if you'd always end up with the same seed

[keen widget]

thank you!

[dawn gazelle]

Point is, you need to convert the string to a numeric value to work with, once you are working with numbers you can use math to do whatever you want to get your seed.

You could do it a bit differently, like say, if you have letters and numbers, you could make a MAP of character (string) > value. Then parse through your string's characters look up the value, and then just add them up to a total.

Okay I know that AddForce is the per-tick one, but on my life I can't remember what the OTHER one is called, the one that's a single big push?

[short bramble]

Hello! Is there a way in BP to get the optional level name of an instanced level? Not the outer>level, but the unique instanced level name of an object is part of that sublevel. Thanks!

[short bramble]

U might want to check both Launch and Impulse.

[frosty heron]

@wispy badger game mode if u want to spawn your character with the game mode.

Game mode base if u dont

[flat coral]

What's Launch I'm not seeing that one

[frosty heron]

Drag from character movement component

[wispy badger]

Hmm. I'd want to spawn my character but manually after some UI animations (Start Game -> Info about the story, etc. -> screen fades -> spawn player)

Would I be able to spawn player via BeginPlay from GameMode or how would it look like?

[flat coral]

Oh I'm not using that for this pawn it's all custom movement

[frosty heron]

You can, I think game mode base is a stripped down version of game mode. I haven't really use it my self.

Alternatively can always override the spawn function and just do your own spawn logic there.

If u want to spawn later then begin gameplay is not the place. You spawn it after Ur story is finished

Hi, I just wanted to share a fundamental knowledge that I missed from UE documentation regarding how Trace Channel works with Block and Overlap settings.

Trace channel on a collision object (static mesh, collision shapes, etc.) must be set to Block for the TraceLineByChannel to pick it up. It will not work if it is set to Overlap.

On the other hand, channel set to Overlap will work with Multi Trace Line By Channel, it will also work for when set to Block. The difference here is that Overlap allows the trace to pass through, reporting the hit, and potentially reporting other hits along the trace, up until an object set to Block is hit - this stops the trace.

I have read through the docs few times and I was unable to locate it, and I figured it out by trial and error. If at least one of you finds it useful, it was worth the effort (doing the screenshots 😉 ).

[wispy badger]

So a custom event would be best I guess?

[wise zodiac]

Hi I have a question, I want to use loading page till all shaders and texture are ready , but it seems that it always fire the event before all loaded .

[frosty heron]

Yup

[frosty heron]

How do u even detect it in the first place?

Streaming is what make the loading faster

[flat coral]

Does BP have a verison of "Final" for methods? That makes them so they can be called by child classes but NOT overridden?

[frosty heron]

I would check what's available on pawn movement. Not sure what's on the menu, only used cmc soo far

[lime basin]

why its so rare to see collapse to node?

its almost never being used by people

[flat coral]

Because why not just collapse to function instead?

[lime basin]

is there something wrong with it?

idk looks better

?

[flat coral]

Honestly I find it collapse to node makes the graph LOOK better, but the price is that both the outer graph AND the inner graph are harder to work with

Collapsed nodes occupy this weird in-between, where they're SORT OF their own function but also not, and it ends up being the worst of both worlds in my opinion.

[wise zodiac]

I tried some plugins and follow after videos

didnt find the way that work

[frosty heron]

No idea with plugin. Gl tho

[pastel skiff]

is there a way to check if the collsion box overlaps with an actor ? and i dont mean evnt begin overlap i mean like if box overlaps with character do something

[frosty heron]

That's what begin overlap is?

[flat coral]

Okay so I'm making a system where a pawn tries to jump at the player, and basically turns into a projectile until it hits something. The problem is that the pawn starts off touching something, whatever surface it's currently on, and my "on hit" just instantly collides with whatever that starting surface is. How do I fix this?

I've tried adding the currently-colliding actor to the ignore list for collisions, but sometimes there are multiple actors involved (EG a floor with a carpet on it, it could hit either). I've considered making it wait a moment before enabling collision, but the jump is pretty fast so dialing in that wait time is really tough and can result in bad behavior too, where it feels like it SHOULD have hit something but doesn't.

[frosty heron]

You can use is overlapping actor node to check

If a comp overlap with something

[pastel skiff]

whats the node called?

[frosty heron]

U r reading it

Isoverlappingactor

[pastel skiff]

dnag im stupid thnaks will try

[soft plinth]

Hi!
How can I rotate the spline section like this...

Because...

[flat coral]

Is this seriously the best way to check whether an actor has a component? Or am I missing a cleaner function?

[supple dome]

theres no better way, although testing if an actor has a component seems counterintuitive (unless its a component that only works on a specific actor)

then you could do what character do, and create a function to get its component, or an interface

[flat coral]

Basically this is a little bug that jumps at you and explodes. But if it misses, it goes back to crawling around. So it needs a way to know what's a potential victim and what's just a wall it hit. I do that by checking whether the impacted actor has my health component, meaning it can take damage

[supple dome]

ah its a different actor, not self

yeah seems ok

[gentle urchin]

Tags?

[flat coral]

I could use tags but this is easier

[gentle urchin]

Let your health component add a health tag to owner

Win win win

Well if you've made up your mind then...

[random pulsar]

please can someone give me a video from youtube how to set up curency system ,i want to spend and add money from different events and the money need to be the same on other levels

i searched in youtube and didnt find

this is not what i need

[gentle urchin]

also you'd usually just do isvalid on it

[gentle urchin]

Custom collision channel

[dawn gazelle]

I'd use an IsValid check on the component rather than checking if != null.

[random pulsar]

maybe the request is not good enough

[gentle urchin]

is it just in-game currency or real life etc aswell ?

if its just copper,silver,gold in-game it should be fairly easy

[flat coral]

Wait but that wouldn't work because the wall it's jumping FROM would be a valid landing spot if it was jumping TO there

[gentle urchin]

Its always nice when details are added after an attempted solution is presented

[random pulsar]

did you ask me or no?

[gentle urchin]

You can have no collision for the first ~second or so? to get off ground

use a smaller collision volume so there's no colliding elements

[gentle urchin]

nobody else is talking about currency atm ^^

[random pulsar]

))

[soft plinth]

Help...
#blueprint message

[random pulsar]

so it will be a simple type of coin,when you exit the game it will not save it,when you go to another level it will save,i want to have a shop where i can buy abilities,skins,and to be able to spend and earn money from different events

[gentle urchin]

show code. Bet you're not setting rotation according to rotation at spline point

you gotta do that for it to follow

[flat coral]

This is what I'm trying first, we'll see how it goes. The problem with this thing is it realllly doesn't respect collision normally very much at all lol but that's it's own issue.

[random pulsar]

@gentle urchin

[gentle urchin]

sounds like you want a currency you can trade with real money

they would be two very different concepts...

[soft plinth]

Thanks...
here...

[gentle urchin]

i believe you need a set rotation aswell

[hoary ore]

What is the most versatile spot to perform calculations between stats and multipliers to affect things like gameplay abilities? What about the most performant spot?

I'm more comfortable with blueprints but if there's a simple way method with C++ I'm happy to try that too.

[soft plinth]

Done, but I need the previous and latter points lo rotate as well but with less intensity to bend it a little without separaring the meshes.

[gentle urchin]

Soo... add that ? 😄

[soft plinth]

Come onnnnnnnn....
This happens....

[gentle urchin]

personally I'd probably use ISM's for this

[lofty rapids]

c++ will be more performant, thats for sure especially if your doing a lot of calculations

[gentle urchin]

not a big fan of the spline meshes

[lofty rapids]

but bp can handle most stuff

[soft plinth]

Alright, can you help with an example using insranced static meshes?

[lime basin]

am I doing it wrong? My progress bar isnt updating but i tested return values of all of them and they work just fine

[hoary ore]

Thanks, I don't know a clean way to handle something like that yet, especially with C++. Wondering if there's a semi-standard data structure/blueprint type to use.

[lofty rapids]

the event is firing ?

[lime basin]

it is but widget progress bar isnt updating

i put print string at end of percent

it fires everytime

[gentle urchin]

sounds like MaxHealth is 0

I prefer passing both current and max with these events

ensures that the calc is correct,

and not relying on secondary stored variables

[steel shadow]

Hello, I'm wondering something how can I make an AI backpeddle for like 30m ?

Does it have to do with

[lime basin]

that just tells you a a direction actor is facing i dont think thats it

[steel shadow]

that worked

if anyone is wondering

[jagged violet]

hello guys I would ask you what it the best course for Beginners in blueprint It doesn't matter if it's paid or free

[spark steppe]

https://dev.epicgames.com/community/learning/courses/3ke/your-first-hour-in-unreal-engine-5-2

and then there are some more by epic with example projects etc.

[gentle urchin]

plenty of learning content

||I think if you pay Ben, he might give you lessons aswell||

[lofty rapids]

you ever programmed before ?

[queen valley]

guys, how do I make it so my actor attaches to the socket? It just stays floating mid air if I disable simulate physics on the fly when its already spawned

why is that?

[jagged violet]

no

I'm 3d artist

[sonic arrow]

ok, so lets say I want 15 guns in my game, what is the best way to implement them with blueprints that doesnt take up much storage

do I put them all in the player? or do I make seperate blueprints per gun that the players blueprint can access?

[gentle urchin]

separate bp's

what storage are you concerend about

most storage comes from assets used

not the bp / script files

[sonic arrow]

oh okay

yeah no I was just tyring to keep download size smaller

since the overall game is a smaller game

[gentle urchin]

use low vert meshes, low res textures, etc

[sonic arrow]

so how should I connect the BPS to the player?

[sonic arrow]

im using 1024x1024 textures for the environment and probably lower res for guns, the games going to have a comic book look

but thers going to be a upgrade system that gives the players new guns as they progress, so they can spend points to upgrade, how should I give the players the next gun?

[random pulsar]

did anyone have this issue with foliage?When i re open the level or open another level and then this,foliage disappears,it says failed to load

[gentle urchin]

Its just a matter of placing a bunch of ism's at decent distances along the spline

[sonic arrow]

hey so for the gun blueprints, should I put all the variables of the gun into the gun blueprint or player blueprint? things like mag cap size, animations, audio?

[gentle urchin]

In the gun bp

in the master_gun bp

[sonic arrow]

man now im confused what do you mean master gun bp?

[gentle urchin]

you'd want to use inheritance to avoid doing the logic several times

so there's gonna be commonalities between all guns

All of them can "Fire"

all of them can "Reload"

all of them got some projectile type

etc etc

all common things go into a parent blueprint

[sonic arrow]

okay? next question do I make the blueprint a pawn or actor?

[gentle urchin]

all specific things (common things specified) goes into child

Actor

It's not directly controllable (as a pawn would be)

[sonic arrow]

okay, and the master gun BP is basically a template to copy paste?

[gentle urchin]

pawns and characters are ment to be possessed by players

[gentle urchin]

not copy paste. Avoid copy paste 🙂

you create one master gun

[sonic arrow]

yeah?

[gentle urchin]

and all other guns are a child of master gun

and if they need some unique things, they simply override what the master gun provides

[sonic arrow]

how would that work? would it all be in one bp or many BP's?

[gentle urchin]

many bps

[sonic arrow]

okay so how do I make child bp's?

[gentle urchin]

so 16 bps for 15 guns

1 master gun
15 child of master gun

Right click the asset -> Make child blueprint

[sonic arrow]

okay, so in the master bp make all the variables, then in the child bps put assets like the model, animations what not, make sure they are children of the master gun?

[gentle urchin]

yepp

master gun also provides a default implementation for the basic events

like Fire
Reload
StopFire
ChangeFireMode (?)

ADS. who knows 😄

only you know

[sonic arrow]

there is going to be ADSing, ill tell you if I Run into any issues

[gentle urchin]

no need to tell me

tell #blueprint

[sonic arrow]

okay

[sonic arrow]

wait one more thing, how do I link sounds and animations to variables?

[gentle urchin]

you create a variable of the correct type in the master_gun,

can leave their defaults to nothing

then in a child bp, you simply select the asset in the details panel

[sonic arrow]

what would be the correct variable type for a animation / sound effect exactly?

[gentle urchin]

AnimMontage

USoundBase perhaps

[sonic arrow]

how do I communicate that the player clicked left mouse button between the gun and player scripts?

[gentle urchin]

Player BP has some variable for the current gun

which is connected to the LMB click event

LMB -> If Gun.IsValid -> Gun.Fire()

[sonic arrow]

so how do I get the script to tell the gun when to fire? do I have to use a event dispatcher or something

[gentle urchin]

You simply call the event on the gun reference

[sonic arrow]

also how do I get the gun in the players hands to begin with? do I just drag it into the playercharacter bp?

[stoic root]

Hi! curious if someone could solve my issue. Im trying to get an object to follow a spline path, and while it does that, it always moves to zero world location when in play mode. Even though i set the spline path at specific points in the environment. Any suggestions?

[gentle urchin]

This really is tutorial material

[sonic arrow]

wdym?

[gentle urchin]

look up a tutorial

for the things you want

[gentle urchin]

any thing peculiar about these points

My car runs smoothly, but it's a rather short track

[stoic root]

theres a spinning blade that should move along the path, however when i go into play mode the whole system appears to move to the 0 world location where the cube is. For clarity, the blade does move and rotate .. its just in the wrong world position, not where the points are on the path.

[sonic arrow]

I actually cant find any tutorial on implementing multiple weapons into a game

I just need to know how im supposed to attach the gun to the player and get the scripts communicating with each other

and then how to switch through guns as the game progresses

[gentle urchin]

is the ref valid ?

[gentle urchin]

you get that from any gun tutorial

[sonic arrow]

wrong

errrr

I just tried watching one and it straight up had no possible way to do multiple guns, the m4 that the tutorial was showing was linked directly to the player, there was no blueprint connections, both the arm and gun models where just part of the controller

im so irritated and I dont know what to od

[gentle urchin]

also watch the pinned link for blueprint communications

[stoic root]

yup, appears to be.

[gentle urchin]

And the distance is within the limitd of the spline?

[gentle urchin]

You're using local vectors

Not world

You want world

[pulsar geode]

Is it possible to reverse the direction of the fade on a niagra beam? Currently the origin is solid with it getting more transparent towards the beam end. Ideally I want it the other way around.

[gentle urchin]

Cant you do a 1- to it

[pulsar geode]

Are you talking about within the material itself?

[gentle urchin]

In niagara, or in the material i guess

Im sure niagara can invert materials

[pulsar geode]

I've searched through the whole Niagra system and I couldn't find an option for it, however, the material already had a 1- in it. Removing it solved it. Thank you.

[golden kite]

I'm building a closed captioning system by spawning Text3D components (for reasons) - 1 for each word - but then after a full line has been built, I'd like to animate the entire line to scroll it upward.

My question is how would you structure this so that you don't have to animate each word individually, but just animate the whole line as an entity. Would you group them (programatically in BP) or parent them, or merge the meshes? What's the simplest approach that lets you transform the entire line as a unit?

[undone bluff]

is there anything else in the actor besides the captions?

you can just move the root component

if not then you attach the text to a scene component that is not the root and move that

[golden kite]

The caption actor spawner has to handle multiple individual lines. Like 3 at a time. So it needs to remain fixed.

[undone bluff]

yea so 1 scene component per line

[golden kite]

I'll need to figure out how to dynamically create these "parent" components (and then destroy them later so I only have like 4 at a time). Is there a base kind of dummy container that's best suited for this?

[undone bluff]

you just add component by class, grab your array of text then attach every index to the scene component you just made

however

you will probably want to make an actor per line or create components you spawn in and destroy to manage individual lines

in blueprints your only real options to animate the upwards movement are tick events and timelines

you cannot make a timeline at runtime

[golden kite]

I like the idea of making a "line" component that you spwan in dynamically and then have a kind of addWord() function that dynamically attaches the word and positions it correctly.

[undone bluff]

yea make a caption manager that spawns caption actors per line

it will make your life much easier for the movement

[golden kite]

I was really hoping to avoid hand-bombing the animation using tick events. Since the movement will always be a fixed distance (like up 100 pixels), I think I can create that timeline and then maybe attach it programmatically...? Never tried that before

Can you just attach various actors to a timeline when you want to animate them and then detach / dispose of them when the animation is done and reuse that timeline for the next ones?

[sonic arrow]

I still am lost trying to setup guns in my game, I am trying to make support for upwards of 15 guns

[undone bluff]

all the timeline does is scale a value over time using a curve

[golden kite]

Or maybe your original idea of moving the whole dang text spawner - it will just get higher and higher but that's prolly ok, since I will be destroying the lines once they should not be visible anymore....

[undone bluff]

you can do that with event tick too, (in fact it's often the better approach)

but the issue is

you need to animate the lines independently

oh wait

only one will move up at a time right?

forget what I said then, silly oversight

[golden kite]

no, your instinct is right. It's kind of a "rolling" 3 lines of text....

[undone bluff]

ah

are they all moving at the same speed?

[golden kite]

The next challenge will be - how do you create a "window" that clips or crops the lines so that when they go outside the window they are no longer visible....

[undone bluff]

yea this is simple

[golden kite]

(don't forget I'm not doing this in UI but as Text3D actors)

[undone bluff]

this is a good usecase of event tick

move all your scene components up a bit every frame and check if they exceed a certain value on their z position, if so destroy them and the attached text components

[golden kite]

hand-bomb it is then

Yes, that is a good approach. The only thing is that the text should get "cropped" by its "window". Like you move the text up and then the tops of the letters are cut off and you move it up some more and more of the letters are cut off and then when the letters are no longer visible you destroy the line. Rinse and repeat. I just don't know how to achieve that 'crop" effect.

Think of scrolling through a web page on your mobile phone or web browser.

[undone bluff]

that has to be done with a shader

[golden kite]

ah sheeeit

tutorial time lol

[undone bluff]

it should be fairly simple though

[golden kite]

You've given me a good start. Appreciat ethe time and the advice

[frank viper]

Hello,
A quick question.
I watched a tutorial on keep persistent information like color material choices stored in variables in the Gamestate and in a GameInstance.
I just dont fully understand why the info would be split up between the Gamestate and the GameInstance.
Why not keep all the info stored in either the GameInstance or the Gamestate?
Does anyone know the answer to this? 🙂
TY 🙂

Does it matter?

I am using event dispatchers to pass on the info to a gamesaveobject.

[undone bluff]

gamestate is just a kind of global gamemode for multiplayer games.
gameinstance is a class that persists from the moment you open the game to the moment you close it, it is where you handle things like saving, loading and level transitions.

[frank viper]

I see

So no disatvantage if I have variables that store info in either or?

It seems you can store it in both

[undone bluff]

well if the level is unloaded so is the gamemode/gamestate

[frank viper]

Or is one better for this use than the other one

I see I have only one level

So if I have only one level in the game it shouldn't matter right?

[valid frigate]

Just wondering.... whats the best practice for having blueprints communicate with each other? Creating a function? so for instance i want up and down buttons for an elevator. The elevator will only go 2 floors. one button on the bottom floor, one button on the top floor and 2 buttons in the elevator. now for this should i be creating blue prints for the buttons with instances or do i make the buttons in the elevator blueprint?

[undone bluff]

I don't know what you are doing, but the color choices, that I presume are dynamic material parameters, should only be relevant to the actors in which they are used

if you want saving/loading then the instance and those actors will be relevant

but I don't see how the gamemode or gamestate are

[frank viper]

I have a customization thing going where the player chooses matrials and colors it builds in a structure.

I see so the game instance would be a better choice to store all those variables in then?

[undone bluff]

yea then the structure should keep its colors, if you, say, have a wall, and you make it red, then that only concerns the wall

it should be keeping its own color

[undone bluff]

for saving and loading yes

[frank viper]

I see ok that answers my question thank you

[undone bluff]

but you'd not really store it there, just use it to manage them

they'd be stored in a savegame object

[frank viper]

Yup I am storing them in the game instance and then it fires over to the savegame object via event dispatchers

So I am using material interfaces

As outputs on the event dispatchers

[undone bluff]

you can probably make the whole elevator a single actor, if that works for you. If you want separate actor buttons you'd use a blueprint interface function that sends over an integer with the floor the button is on to tell it to move there

though if the buttons are only ever used with the elevator and you don't want them for anything else

you can really just cast

have an elevator reference as a public variable on the buttons as well as the floor and you're good to go

the buttons in the elevator should be part of the elevator

[frank viper]

Thanks for the input appriate it 🙂

[valid frigate]

I'm wanting to figure out how actors can interact with each other for learning purposes. honestly i want it to only work when the power is activated and then work from buttons on each floor.

The buttons in the elevator are part of the elevator BP but its hard to figure out placement for the ones outside. I really just want to figure out BP interactions

[undone bluff]

if you have like a power generator, give it an array to store all the things it powers and if it is shut on or off you can use a blueprint interface or event dispatcher to notify the connected blueprints

then they can store whether they are powered in a boolean locally

or you can go the other way around and make everything query if it has a valid power source

https://docs.unrealengine.com/5.3/en-US/blueprint-communication-usage-in-unreal-engine/

https://docs.unrealengine.com/5.3/en-US/how-to-use-blueprint-communications-in-unreal-engine/

[valid frigate]

TY i've checked it out but its a little greek to me, i learn much better when having guidance and asking questions

ADHD brain

[undone bluff]

what isn't covered here is actor components

they are also a vital communication tool

[valid frigate]

I'll read it over again after my class

[undone bluff]

because you can pretty safely hard reference those

kinda like interfaces but you can handle implementation

[valid frigate]

I'm doing druid mechanics courses on udemy and a few courses on youtube and GameDev.tv

It's nice having so many different ways to achieve things. but its a bit overwhelming lol

yea it takes some experience to know what to do when

[jolly cipher]

Hello!

New to Overlay materials. I was trying to simply set an Overlay material via blueprint using the mesh as target.
Nothing seems to happen.

So I manually add the over material on the mesh, still nothing.
If I add an index in the Overlay Materials and then add it, that seems to work
Just not sure I understand why / how to make it work via blueprints

[valid frigate]

I did some stuff for functionality of a basic elevator for my level design class because i've only been working with box collision triggers. he told me to use flip flop instead of = for up and down

[fleet sigil]

One of my bps never seems to leave the unsaved state. When I close and save all it does not lose anything but once launched it's unsaved again. Should i be worried?

[slate fable]

I'm trying to make a d20 physically in the game. I want to be able to roll the dice In a 3d space but also have it calculate a number for combat

Kinda specific because it needs to be able to be rolled to tabulate a few different things

[silk cosmos]

Question for anyone familiar with the Common UI plugin. I have 3 common activateable widget stacks for adding and removing different menu types (game, menu, and modal). When I trigger my button to open my pause menu im pushing a common activateable widget to my menu stack. This all works fine. Im running into an issue however where in my pause menu I have a button to open my settings. I was just going to push another common activatable widget to my menu stack once the button was pressed, however for some reason its displaying it behind my pause menu (the activatable widget I had already pushed to the stack). I was under the impression the last pushed widget of a stack would display on top of the other widgets in the same stack? I can deactivate my pause menu, but then you get the weird fade in and out transitions from the activatable stack for both widgets when you close the settings menu (which I want, just not in this specific situation as it looks weird).

[silk cosmos]

I was pushing it to the wrong stack. I even checked it like 5+ times too. Thats an hour I'll never get back

[cold lion]

Is there a way to prevent the CharacterMovement Component from randomly corrupting? I am in UE5 and this keeps happening

[valid frigate]

oh really?

[frail onyx]

Anyone know how to go about making a pressure plate that works with a physics simulated cube, not with playing a timeline on the cube hitting it, but like actual physics when placing the cube on the pressure plate itll weigh it down which will activate the door at a certain point and when you lift it the pressure plate will rise up as your lifting it. I tried looking for some tutorials about it and coundn't seem to find anything

[empty mural]

Is there a good way to add additional collision spheres to body parts or weapons to block characters from phasing through walls? I can get a static sphere to block movement, but I can't attach it to anything and get a good result.

[frank viper]

Anyone tried to set Chat GBT up to do repetitive coding in BP?
I have miles of code I have to do with saving and loading in UE4 and just wondering how I can create some kind of "macro" that just changes variables but repeats code in BP.

A lot of it is copy and paste but I have to change variables and a few nodes here and there.

[lunar sleet]

No. Chat GPT is crap at UE

If you have to repeat yourself that many times, you should prly look into learning inheritance, bp function libraries, and so on

[frank viper]

Your'e right I should use more functions.

Prob is there is so much change I have to do with each repeat that it would create massive functions with so many variables that I might as well just code it without a function.

I knew this when I started the project though I was one the fence weather I should create bigger functions or break things up into more "sections" of code.

[undone bluff]

yea, I do lots of physics stuff like that in my game, including proper pressure plates

unfortunately I could never get those to really work 100% reliably

the force actually exerted on it can vary a good bit

and I was never able to calculate what to set the physics constraints to based on target weight

[molten yew]

Where are public variables in a level blueprint located in the editer?

[undone bluff]

I'd think nowhere

there isn't really any per instance editing for levels afaik

[molten yew]

hm, is there any point to making a variable public in the level bp?

[undone bluff]

no, not really

though I don't think there is any point to make a variable in the level bp at all

[lunar sleet]

Refactoring is life

[dusty flint]

does anyone know how is this node called?

[frosty heron]

Increment @dusty flint

If you are looking for the opposite , that would be decrement

[dusty flint]

OMG!! thank you so much <3

[frosty heron]

Shouldn't even use level bp 99% of the time

[undone bluff]

I only found out about increment in blueprints recently

immediately went to replace all my add 1 > set nodes

[molten yew]

What should I use to mess around with my directional sunlight?

[frosty heron]

I would make a bp with a directional light component

And just drop it to the level I want

[undone bluff]

I like putting all the sky and atmosphere stuff in a single actor

like coldsummer suggested

but you can make a separate manager too

[molten yew]

Man I'm dumb completely forgot you can do that. Prob cuz unreal just has it built in the level

[frosty heron]

Less nods is soo much better. Bp become spaghetti monster fairly quickly

[undone bluff]

which is why I still don't get why we use get nodes

control rig did away with them mostly

[frosty heron]

I actually have 2 directional light for my purpose. So I make a bp that also tell my directional light to be rotated according to player control rotation for my need.

Saves me time copy pasting logic by having it in a single bp. I just drop my custom directional light bp to every level

[molten yew]

Yea that's a good idea. Thanks!

[dusty flint]

Hi! i have one question, could i end a simulation with a node?

[frosty heron]

Simulation is just playing without possessing any character

You can exit play with a bp node

[frail onyx]

https://www.youtube.com/watch?v=WiDWeb89W58&t=111s anyone know how to make a item slot system that generates an output when the item is in the slot like the one shown at 0:13 in this video?

[gentle urchin]

Did world space fix it ?

[viscid flower]

I am using this BP to throw a ball and to trigger ragdoll to the actor that gets hit. The ragdoll only seems to get triggered when the character walks into it, but not when it was hit by it from the throw :/ Anyone know why?

Throw:

I tried having the collision set up to ragdoll and block all. Still have the same issue. It doesn't work when it's hit by the ball. Only when they hit it by walking into it.

[queen heron]

I've made this little blueprint setup where I get the angle distance between two rotators
it works ok, but the issue is that the values only go into positive

I need to make it go to positive and negative depending on the rotation direction

[queen heron]

make sure the actor that is hit has "Simulate Hit Events" enabled

same for the thrown actor

[viscid flower]

yeah I have this checked

oh maybe I didn't for the thrown actor

[main lake]

First you have to watch a tutorial to learn how to do the system where you can pick objects in front of you. For the slot, it's easy, it's just an actor with a collision box in it that checks (cast) to your "cube" actor when it begin overlap with it, if the cast succeed that means you put the right actor, then you can call your logic to open the door

[queen heron]

maybe if I multiply the acos result with the right vector?

[viscid flower]

I have it enabled on all of them X(

[queen heron]

try using the print strings to debug the functionalities

[frail onyx]

ok, i have a pickup system where it lets me pick up any object with physics, and i have a cube bp called physics cube which i have placed. Do u know how i can make it check to see which specific item actor is grabbed and then if that specific actor enters the slot bp collision it will automatically make me stop grabbing it and smoothly move it to the targeted spot

[queen heron]

hmmm, nop, didn't work

[frail onyx]

also this is the main code i have for my grabbing system

[half swallow]

Let's say that I have 9 separate Blueprints all placed into a level, all basically the same save for different static meshes; how much performance impact is it compared to having 1 single parent BP placed 9 times in the level?

[main lake]

When the object enter the "begin overlap" of the collision box, you :
0 - Cast to see if the actor who overlapped the box collision is your cube
1 - Disable its physics
2 - You set the boolean "IsGrabbingObject" on your player to "false"
3 - You get the reference of the actor who entered the box collision from the "begin overlap event" and you set its position to the final position inside the slot

[gentle urchin]

Nothing to ever talk about again unless some stat shows you that its an issue

It depends on the assets usedmim the bp, how they are loaded, and so on. Script in isolation takes up virtually no space at all

With that being said, im a fan of not repeating work so i'd have 1 placed 9 times.

[main lake]

You forgot to divide by the (mag a * mag b) https://youtu.be/WDdR5s0C4cY

[half swallow]

yeah same; i'm just updating some outdated assets in the team project i'm working on

just wondering if it's worth the hassle at all of asking the environment artist to make sure everything's fine after i consolidate the BPs

i'll still just do it; makes the workflow of updating the code in them much easier

[gentle urchin]

Worth the hassle almost every day

[queen heron]

there's no mag in blueprint

[rare moss]

im pretty sure its magnitude but im not sure if that node exists either

[queen heron]

its what I just said

[sonic crest]

What's the shortcut key to navigate to the content browser of the bp class that im currently in?

[spark steppe]

CTRL + B

according to the tooltip on the button

[sonic crest]

Thanks so much

Gotta remember that

I keep forgetting

[spark steppe]

just remember that there is a button right next to the save icon

[sonic crest]

Lmfao
I went in the editor settings and looked through the shortcut key and did not find any

And it was there the whole time

[main lake]

It's called "Vector Length"

[gentle urchin]

From forward vectors?

They already normalized

[queen heron]

all I want is to get the angle distance between the two rotators and also want the angle distance result to go negative aswell, not just positive depending on the direction which the control rotation is rotating to

[main lake]

In the video they don't use the "GetFowardVector" so maybe that's the cause of your issue ?

[gentle urchin]

You gotta add that manually

Wether its CW or CCW

[frail onyx]

ok thanks! I'm pretty sure i got it working good now, only thing is since i set simulate physics to false it will not let me pick it back up since it isn't simulating physics and i can only pickup objects that are simulating physics.

[main lake]

Then I guess don't disable simulating physics

[queen heron]

got it working nice and fine with this

[frail onyx]

the only problem is if i keep simulating physics on when it goes into the slot it kinda glitches out and pops out cause its colliding with the slot im putting it into a little bit, and i also dont want to be able the player to be able to knock it out by accidentally walking into it

do u have any ideas for a possible fix?

[queen heron]

you simply need to disable the physics when you don't want them to work

[frail onyx]

yeah but my cube can only be grabbed if it is simulating physics, so i wont be able to grab it again to take it out

[main lake]

to fix it you will need to change your code to let you pick objects even if they don't have physics on the first place like for instance by creating a parent class that will be the base class of all your pickable actors that you will derive from and cast to that class when you want to pick up that object and enable physics only when you release your mouse to release the actor

[queen heron]

you might need this

unless its that what you're using?

[frail onyx]

i dont think so im just using E key event when held down my objects is being held and as soon as i let go it drops

[queen heron]

wait, what are you using to grab the object with?

is it a character?

[frail onyx]

Yeah, and the code i have for it is in my FirstPersonBP

[queen heron]

and whats the slot?

[frail onyx]

is this code in its own bp with a few cubes to make up the model and box collision

[main lake]

Do what I told you to do 🙂

[frail onyx]

im not exactly sure how to make it so it doesn't need physics to grab it though, i watched a tutorial and it just says that it wont work if simulate physics isnt on for the cube

[main lake]

Do you understand inheritence ?

[frail onyx]

uh not really

[main lake]

Do you have other actors that you want to pickup besides your "Cubes" ?

[frail onyx]

no, well i originally had it so i could pickup any thing that i placed in my scene that had simulate physics on, but now its just an actor i have called BP_PhysicsCube and i might add more different ones that server different purposed like BP_PhysicsBattery which are batteries i can grab

[main lake]

Then do you know how to use tags ?

[frail onyx]

no

is it like the trace responses?

so if the trace response comes back as an item that is grabable then i can grab it?

[main lake]

kinda https://youtu.be/Zjh2sRWFAvI

You can use this and you put tags on your pickable objects and when you press E to do the raycast it checks if the actor it hits has the tag you set, if yes then you can call your logic like you're doing above, so that way you don't use physics as criteria to pick up objects

and this will solve your issue with the slot where you will need to disable physics

but with tags you will be able to pick it up again and then you will be able to enable its physics again

[frail onyx]

ok i added a tag to my BP_PhysicsCube and make it check first to see if the hit actor has tag and if it does then it will grab the component, but it still only seems to work if i have physics set to on

[main lake]

Enable the physics first before grabbing

[frail onyx]

wait where like after my 2nd branch node there?

[main lake]

yes on the true of the second branch

[frail onyx]

how do i get a reference to change it on my main bp?

or do i just drag out from the hit component or hit actor?

[main lake]

get the hit actor

or hit the component rather

as the physics is applied on the component if I'm not mistaking

the physics is on your component or the root of the BP ?

[frail onyx]

on the static mesh which is a cube so yah

nice it works now thanks!

only weird thing is i have a delay until i can pick it back up again

[main lake]

the slot part works too ?

[frail onyx]

im pretty sure yeah

if i get in range of the slot collision it smoothly lerps to the location

and then if i press e to pick it back up it lets me do it

there is just a short delay though

[main lake]

I have no clue what's the reason of the delay

maybe it's because you're enabling physics too fast as it's still colliding with the slot

[frail onyx]

could it be cause the timeline is 2 second long so it needs to finish that out fully before it can let me grab it

[main lake]

yeah maybe

[frail onyx]

alr yeah that was it, everything should be fully sorted out now, only thing i need to do now is make sure i cant put in an actor if one is already inside but i should be able to figure that out.

thanks for all the help!

[trim matrix]

Does anyone has/know a blueprint tutorial about inventory system with auto pickup instead of using button like [E]?

You know, just like minecraft when they autopick the loot

[main lake]

https://youtu.be/TcTxSyk8Vks

[trim matrix]

Oooh! That's good and thanks for that!

[gentle urchin]

Auto pickup is just entering the pickuprange and instead of presenting the option you simply try to add it to the inventory

[main lake]

General question : I keep seeing on most (if not every) tutorial about inventory, that when they're displaying the items in your inventory, they always clear the whole inventory icons before adding the icons back again with the new added item. Is it the only and best solution to do inventories ?

[gentle urchin]

No

Its lazy

But its also 'safe'

In case you failed updating some slot somewhere

There's no issues doing delta updates

@main lake in case you wanted a tag

[dark drum]

It depends what you're doing. Event dispatchers are useful in enabling you to only update a single slot.

[main lake]

yes please I like tags, what are "delta updates" ?

[main lake]

How ? Do you need 1 event dispatcher per slot ?

[gentle urchin]

No, just a dispatcher with slot id

Delta - only update the things that changed

The difference

[dark drum]

Have an 'OnSlotUpdated' event dispatcher on your inventory component that is called when a slot is updated. Make it have an input of the slot id.

When you create the slot, have it bind to event dispatcher. The event it calls should check the updated slot id, if it matches it's assigned slot id, it can then call a function to update the slot.

Something along those lines.

[gentle urchin]

^ i just let the inventory bins to it

Then route it to the correct slot

Avoids x amount of bindings

Saving that performance 😎

[dark drum]

Yea, still early for me lol but yea, if you have a slot container, you could just have the slot container bind to it and call the update slot function on the relevant slot, assuming the container is keeping track of the widgets and its slot.

[gentle urchin]

Both methods are imo superior to clearing and recreating the entire inventory everh time

[dark drum]

I would agree. Unless you actually need to update a large portion of the slots, updating only the slot that changes is much more efficient and allows for a more responsive UI.

Having said that though if you only have a small number of slots (a handful) you might as well just clear them all haha. This probably isn't the case for most games though.

[gentle urchin]

I suppose thats fair

No need to over enginneer a 4 slot inventory i guess

[wild crater]

I have a really strange issue. So I made a some BP structs (I know it's recommended to make them in C++, but I did it anyway for now) to be able to have a map of maps. The key value of the map is a struct with 2 enums. Whenever I set something to "None" which is the first value of that enum and I compile the BP, it's being set to "Metal" which is the last enum value...

yea pretty sure I found a bug in the editor... (4.25)

[dry sleet]

sure sounds like it

are the enums also bp?

[wild crater]

yes

I'll probably try to reduce the nested structs first and if that doesn't work, declare everything in c++

[dry sleet]

Yeah, no clue with 4.25, sorry

[wild crater]

lol I seem to have found another bug. By making a map of those types straight up (not putting the map in a struct). Now when I add a second element to the map, save and compile. It suddenly only has one element lol.

pretty astounding

it only happens when one of the enum values are "None"

[dry sleet]

I guess it's related

If the enum seems to lose track of itself like that it makes sense that it'd also happen when used as a key.

[wild crater]

Do you think moving it to C++ would solve it?

[dry sleet]

I'd say chances are good but not guaranteed.

At least you have the enum and struct clearly defined in front of you, not relying on some BP autogen mumbo jumbo

[main lake]

If we unpossess a character and destroy it, and then later spawn a new one and possess it, would it reset to default all the variables on the player or will it keep the values of the variables on the player ?

[wild crater]

true

I'll try it, it's my best bet

[sonic crest]

I started with Structs in C++
Felt much better, now working on my project from BP to C++
It's going great for now, previous stuff that didn't really work as expected, worked well in C++

And much cleaner

[dry sleet]

If you destroy the character and spawn a new one, the new one will be set to the defaults from the archetype.

Unless you save it somehow.

[wild crater]

I generally prefer C++ but I'm working in an old BP project and am the only one on the project that knows C++ so I can't just put everything in C++.

[main lake]

So I guess that's where PlayerControllers and PlayerState come into play ?

[dry sleet]

It's also very nice not to have to worry that you'll need access to the struct in C++ much later on in the project, and have to refactor.

[wild crater]

yup

[dry sleet]

I haven't worked much with PlayerState since our game is singleplayer. We save the player state using SPUD (https://github.com/sinbad/SPUD).

[wild crater]

something else: Whenever I edit a map like this, it collapses all of its elements which is annoying. Is there a way to disable this?

[dry sleet]

That drove me nuts too.

[sonic crest]

Same here. Been working on this project for 2 years, but I just wanted C++
Because, stuff felt like, laggy? And idk. BP is great but C++ is better. Ifc nothing for everything. And I'm working alone as well. Learning quite a lot

[dry sleet]

I haven't found a reason to edit pure maps for a long time, though. Used Datatables or Assets for most things as of late.

[sonic crest]

Exactly, I'm redoing my Structs and enums and other static data in C++

Handling them in C++ and other places where they remain in BP.

[dry sleet]

When compiling the BP graph takes a second or two it feels so... icky. BP is great for some things but having a C++ base gives me peace of mind.

[sonic crest]

Not much fan of DataTables, since they're read only. Sometimes I kinda wanna tweak that value, but resulted in just using the Struct.

[dry sleet]

I don't like DataTables either since they're binary blobs, instead I prefer Data Assets (the new hot thing).

[wild crater]

I'm making a data structure that stores the impact sounds by material pairs (sounds of 2 material types colliding). So the key value is a pair and then the value is 2 sounds. This I'm putting in another map keyed by item type. Is that something you'd put in a DataTable instead?

[dry sleet]

But you can use the base values from the Data Asset and populate a map automatically, that you can then tweak.

[sonic crest]

Exactly. I did a base c++ class for my player and my enemies. Easier to deal with. Redoing functions in C++ and just hooking up things in my player.

[dry sleet]

Doesn't always work, but sometimes it does.

[wild crater]

Yea I like Data Assets. But seemed more like a thing you'd use if you want more than one instance of it?

[sonic crest]

Never had a chance to use Data Assets. But more and more I kinda wanna start using it

[dry sleet]

Ah, cool. I don't know, actually, maybe having a DA system would just overcomplicate things.

The way you're doing it sounds fine.

Apart from the bugs!

[sonic crest]

DataTables are just general tables where it just defines something for an object. Like weight or anything else that won't be edited anywhere

[sonic crest]

That's what I like to do know. I've seen some videos about Data Assets but I just can't find a place where to use that

[wild crater]

Yea I kind of understand the use case. But whenever I considered using them there was a missing feature or like you said the fact that it can't be edited

[dry sleet]

The common "first use case" is inventory item definitions.

Like how you can define all the parameters of an item using the DA.

[wild crater]

I've been using Data Assets for content creation. For instance we have shop recipes that determine how the shop gets populated, the different recipes are in data assets which makes it easy to create content in separate assets and refer to them.

[sonic crest]

And can be edited?

[wild crater]

Not at runtime

[dry sleet]

It can't be edited at runtime (or at least shouldn't).

[wild crater]

Afaik the intended use case is to create content

[dry sleet]

Usually you create some container to hold a reference to the base DA, then any metadata that should be unique to that instance.

[sonic crest]

So, I have weapons 13 of them. All different usages

And I'm handling their data in a struct. When I need to fire, I just call that struct and get the, let's say Ammo Type or Trave distance or Ammo Amount... Etc, there's quite a lot of stuff. Plus these values can be upgraded or changed.

Is it fine??

Now I have an Inventory System and I think Data Assets with me are the best for that system.

[trim matrix]

Anyone know a tutorial for making list-based inventory system? I always find slot-based instead and since I new to this I can't modify or convert the slot-based to list-based

[wild crater]

Though a use case I've tried is to have some data that doesn't exist at runtime. I have an editor widget that can toggle debug settings at edit time, I store these in a data asset so I don't have to toggle everything when I run the game, just once when I launch the editor.

[sonic crest]

ListView?

[trim matrix]

Kind of like only the item name, like in many JRPG

[sonic crest]

Also, if I have 13 weapons, some of em just small differences, like damage for instance.

Is it worth having 13 Data Assets for that?

[dry sleet]

The main advantage of DA over DT here is that you don't have all your weapons in one big chunk. Say you have another person on your team that also need to edit item definitions. If you have a DT you need to check out the whole thing and only one person can edit it at once -- but with a DA you only need the item definition of the specific item you want to touch.

[wild crater]

You could put the struct in a Data Asset. This is where you would create the content. Then in gameplay you can just get the struct from it and use the data. Any data that changes though, you'd have to store separately. Like whether it's upgraded or not.

[wild crater]

Yea and maybe linking BP's to data by referencing one DA. I guess if it's in a DT, your BP still has to extract the correct data from the DT no?

[dry sleet]

Yes, and you need a reference to the correct DT somehow, too.

[sonic crest]

Hmm

[dry sleet]

Unreal has a wonderful thing for DA:s called PrimaryDataAssets.

That's definitely over to #cpp territory, but the gist is that you can request them by name.

You give the data asset an ID which you can then use to load it.

You can also load it asynchronously very easily, and what's more you can request Unreal to also load all soft references contained within the DA if desired.

Ah, maybe too in-depth, but it's a very nice thing to look into if you're interested in a more data driven system!

[dry sleet]

(the idea being that if you only want to show some text from a DA, for instance in a inventory screen, you don't need to load the meshes for it -- but if you want to show the entire item you can automatically request them to be loaded at the same time)

[sonic crest]

I'm sorry, I'm still blank about Data Assets.
I created a Primary Data Asset
Added the Struct. If I have 13 weapons, do I have to have 13 PDA? And how would I retrieve that information?

[dry sleet]

Sure, have 13 instances of that PDA.

[sonic crest]

Ehh

[dry sleet]

You create them using the right click menu (Create Advanced Asset -> Miscellaneous -> Data Asset).

For instance here's some junk DA:s from our game.

[wild crater]

Well. If the weapons also still have their own BP. Maybe this isn't the best use case? Unless you want the DA's to get data for your inventory without having to instantiate the BP's?

[dry sleet]

The item definition can include the base class of the item to spawn.

[sonic crest]

Weapons do have their own BP yes. I was thinking mostly of the weapon data like damage, range, traces... Etc

Maybe you're right, not the best use case for Data Assets. Will definitely use it for my Inventory system tho.

[dry sleet]

Every usage of a Data Table is better suited as a Data Asset.

Don't need a PRIMARY data asset in this case.

Just create a DA property on your weapon that you can slot a weapon data definition inside.

[sonic crest]

Got these. Apologies for phone picture, I don't have discord on my laptop

[dry sleet]

You'll need to define your data asset format too.

With a class that inherits from I believe UDataAsset

Then inside that, just like a DT row struct, you define all your damage stats and such

[sonic crest]

Create it in C++ then use it as the base in BP

[dry sleet]

Exactly.

Maybe we should jump to #cpp ? :)

[sonic crest]

No no im not using DT. I do NOT have my weapon data as DT. Just as C++ struct.

[dry sleet]

Aha.

[sonic crest]

Slipped a bit there.

[dry sleet]

Well, the Data Asset is just like a slottable struct.

That you can create and edit separately from the BP it resides in.

It can be nice, in your case, perhaps, if you want to have many weapons that share the same stats.

[wild crater]

When I think of DA's, I think mostly of cases where the only difference between objects is data. I guess the way you propose to do it @dry sleet is to put the base class for the item in the DA as well and then when a weapon is instantiated from a DA, it populates that base class object with the data from the DA? So you don't need a separate BP for each?

[sonic crest]

They do share the same states, maybe 90% same 10% different. Some have BP some don't.

[wild crater]

Also this!

[sonic crest]

Mostly damage, range

[dry sleet]

That could be a way of doing it. We do it that way when spawning inventory items. That way you can have a lot of variations that just edit some aspects of the weapon.

But it's equally fine to just have BP:s with slots for the DA that can be queried for damage stats :)

[dark fox]

Created 13 different Data assets for weapons is same is creating 13 rows in Data table you can't avoid that but I am guessing you don't want to put shared values (for example sounds) in all 13 of them separately. You can do this by creating a separate Data Asset specific for Gun sounds and put a variable for it in your main weapon structure for Gun Sound asset. This way you can share some properties. Like here I can share Abilities and Cosmetics in my weapons.

[sonic crest]

I see

[dry sleet]

Haha, I got a little carried away in this discussion and I should probably get back to work, but holler if you have any DA questions and I can maybe answer them later. Also the folks in #cpp love discussing DA:s :)

[sonic crest]

That would be a lot of data assets then.

[dry sleet]

Not a problem. They're only loaded on demand.

And file size is teensy

Indeed, a DT with lots of structs takes up more memory when loaded because it must load all the rows no matter what.

[sonic crest]

I'll see what's best for my weapon. I'll mostly remain on the Struct. But for my Inventory System I'll definitely be using Data Assets.

Thanks Olaxan, take care)

[dry sleet]

Yeah, no need to refactor before you get the hang of it! Trying it on something new and then going back to use the newfound knowledge is probably best!

You too!

[sonic crest]

Will do 🍻

[rancid moat]

The issue occure because we have 2 sets of Logitech wheels, the G920 and the G25, and I want to set my IMC accordingly., so I get the Product ID to test things.

[wild crater]

update @dry sleet . I declared the structs and enum in C++ and now it seems to work as expected lol

pretty crazy that it's just broken though lol. But maybe not anymore in modern engine versions

[dry sleet]

A lot of things are broken in Unreal haha, but yeah, that's an old version for sure

[wild crater]

the more you try to do more advanced stuff in Unreal the more the cracks start to show

still an amazing piece of software though

[dry sleet]

Most of the modern systems feel fairly robust*, but some of the very fundamental things are janky

Like attachment

[thin panther]

Oh blueprint structs and enums are super broken and have been for years.

Epic like to pretend they aren't though

[dry sleet]

*) Exceptions apply

[wild crater]

component attachment?

[wild crater]

Yea i keep hearing it. But the only evidence of it I had seen was loss of data. I didn't know there were also bugs like these. And I guess the fact that structs can't have functions in BP sucks a lot too.

[dry sleet]

Yeah, comp. attachment and mobility.

[thin panther]

I've flat out had them irreversibly destroy a project (when I wasn't using source control)

[dry sleet]

There's a annoying bug where you can't edit mobility on instances of BP:s that are mixed C++ and BP added comps.

[thin panther]

Nothing like using a struct and boom, your project can't load anymore

[frosty heron]

@thin panther what could happen with enum?

[thin panther]

The amount of packaging errors can be insane too

[wild crater]

sounds awful

[thin panther]

Pretty much the same as structs, they are flawed in the same way.

You normally notice it less as people don't change it use them as often though

[wild crater]

lol now I'm trying to delete the BP structs and the editor keeps freezing, they don't want me to move to cpp

[thin panther]

Id like to point out that's only for BP ones, c++ ones are safe

[sonic crest]

Was working on C++
And it just suddenly doesn't wanna work anymore, lol. Had to get my backup.

[wild crater]

at least it's freezing consistently lol

[frosty heron]

I still use bp enums when I just want to make enums for my page since I do widgets in blueprint

wouldn't use it for any other purpose tho

cuz I can't access the enum from cpp class

but it takes no effort to declare them enum in cpp too 🤷‍♂️ . Should have done that I guess

[sonic crest]

Been there, but it seemed okay with it afterwards

Yeah I don't. I just copy paste backups. I know it's sucky but

I definitely will someday have version control tho. I used backups because my internet was garbage and sometimes it doesn't work

But thanks for the pin

[wild crater]

just do it man, you'll never go back

[thin panther]

You don't need internet to use git

[sonic crest]

Aha

[thin panther]

You don't have to have a remote on the cloud, your remote could just be another location on your computer

I'm pretty sure Laura uses a local remote right?

[sonic crest]

I'll look into it and set it up then

Thanks

[steel shadow]

In my case my source control somehow 'broke' midway through the project and idk how to get it setup again maybe in a different form

I had to disable it

[bitter wedge]

hey guys i have a question, for my internship i need to make a cube that moves based on if you move a slider. i have tried a couple of things but i'm actually giving up. I cant seem to get it working

this is my current setup but it just gives me this error: User
Blueprint Runtime Error: "Accessed None trying to read property ScalableCube". Node: Set Actor Scale 3D Graph: EventGraph Function: Execute Ubergraph Scale Control Widget Blueprint: ScaleControlWidget

[sonic crest]

Slide_69

Nice

How are you referencing your cube tho?

[bitter wedge]

i made a variable and i chose it as an actor in the variable type

[sonic crest]

Yeah but you need something to reference your cube from the world

It can't know which one

[bitter wedge]

i have a blueprint with a cube in it

and i referenced the actor in the variable type

[sonic crest]

You have the cube here, which is public or instance editable.

When you open your widget, show me how you're opening the widget and what cube you're passing through it

[bitter wedge]

i'm still new in all this. i usually work in blender

[sonic crest]

Send pictures

[bitter wedge]

okay wait

[thin panther]

Pins of #ue5-general if you're new :)
There's a learning portal with official materials to get you down with the basics

[bitter wedge]

this is one

[sonic crest]

No. How are you opening the widget

[bitter wedge]

double clicking the widget blueprint and then i go into graph

[sonic crest]

Create widget, where are you calling it

By node I mean.

Ok, when you start the game. Does the widget appears directly? Or when you press a button?

[bitter wedge]

oooh i put in in the first person actor

wait

[bitter wedge]

it appears when i click one time

[sonic crest]

Is that on an input ?

[bitter wedge]

yeah

[sonic crest]

Why

[bitter wedge]

on enhanced input action blablab

[bitter wedge]

i am not sure

[sonic crest]

If you want it to open once directly, just use your BeginPlay

[bitter wedge]

okay

i did that now

[sonic crest]

And, if there's only one instance of the cube is the world, GetActorOfClass and reference your cube

Back to your widget, click on your Variable cube, expose on spawn

Then back to your character, plug your GetActorOfClass Object into your Cube from the create widget

[thin panther]

#blueprint message

Just throwing this one here for visibility again

[bitter wedge]

okay im going to try this

[sonic crest]

Alright

[twin sedge]

Hey yall, kinda first time using animations in ue5, so i followed a tutorial and most things are working. My character just has a idle animation and a walking blend space. For the blendspace im using the speed and direction of the character to determine which animation should be displayed. Ive already checked if both variables getting changed, both do. The speed gets recognized, so the right animation for forward and backwards gets displayed. The problem is that the blendspace doesnt get the direction. In the animation blueprint the value of the direction is getting changed, but the blendspace somehow doesnt recieve it. Does anyone know why or could help me somehow? Btw i dont really get why the speed and the direction is zero while its not zero, as if the variable has two values at the same time. I think that might be the problem, that the correct value gets overwritten by zero, but no clue why that is happening.

[bitter wedge]

will this fix that my cube isnt scaling?

[frosty heron]

Check if you have more than one instance of w/e use that anim instance class in your world

[sonic crest]

It will get rid of your error

And will probably scale

[twin sedge]

How do i do that? I assumed the anim instance would instantly be coupled with my character

[frosty heron]

I'm saying you might have multiple character in the world, hence the existance of multiple anim instance

where one is having it's direction changed (because you control it with input for example) and where the other one is stationary, hence 0

Play in editor and check if u only have 1 character

[sonic crest]

One for Player one for other maybe?

Try adding to your prints (get owner)

[twin sedge]

I only have one, but the thing is the game is gonna be a local coop game so at some point there will be multiple characters, but right now there was only one

[sonic crest]

Hmm. Try adding GetOwner and see what it give you.

[frosty heron]

Go play in pie and go to outliner and filter it with your character name

screen shoot the result

or this #blueprint message

[twin sedge]

When i click on it nothing happens...

[frosty heron]

looks like there isn't multiple instance of the character. So no more idea at this point

best bet is probably to debug and find out why you don't get the values you wanted

[red cape]

does anyone know why the camera shifts like this?

[spiral swift]

Hi, I'm not sure it's cpp issue or blueprint issue.
I've registered a lot of abilities to the default character's character controller, including moving, jumping, and moving the view, and in game I'm trying to possess this controller to another spawned pawn via a key event, at which point the pawn loses all of previous abilities and is able to simply move via WASD/space movement (not triggered by ability), and so far everything worked fine.
But when I triggered the key event again, trying to re-possess the controller to the previous character, the ability to move/jump/move the viewp, etc., that it was supposed to have, disappeared, and I was unable to do anything.
What do you guys think this might be and any ideas on how to fix it?

[sonic crest]

Is your camera colliding with something?

[red cape]

nope

[sonic crest]

Your cam has no collision?

[red cape]

can't find any collision settings for mycamera only forthe camera boom

[sonic crest]

Why handling it in the Controller instead of your Character?

[sonic crest]

And it's set to NoColllision?

Where are you changing your camera location other than following the player

[twin sedge]

hmm okay, still appreciate the help

[red cape]

im not, its only following the player

[spiral swift]

because I want to move a temporary pawn like a movable camera. and I need keep character there but not change the meshes/location/etc..
so I possess the controller to the pawn I want to controll, am I wrong？

[sonic crest]

<@&213101288538374145>

Please don't click that link.

[sonic crest]

Try using your player state instead of contrôler

[spiral swift]

Could you please be more details? what should I do?

[sonic crest]

Test

Couldn't send messages for some reason

I'd ask in #gameplay-ability-system
I'm not good with GAS

But I'd use Player State for that.

[thin panther]

Yeah we already directed there from the #cpp crosspost too.

Heyo, I want to make it to where the player can remap the keys to anything they want, but I've watched countless tutorials and I can't get anything to work, nor understand how what works and what doesn't and why. I would love some help with this.

I already have an options/controls widget, with InputKeySelectors in it, and mappings for the inital keybinds, (enhanced input mappings), I'm just not sure where to go from here

My Straight to the point Question: I want to know how to allow the player to change their keybinds during runtime, and have them persist on a Widget and mapping context after exiting and opening the game again

Is there a way to resize behaviour tree nodes so that if i have large annotations they dont extend to the end of the known universe?

[simple echo]

How can I move an actor along a path? for example, If I have the formula of a circle, How can I get the actor to move along that path?

[spiral kite]

how can I assign skeletal mesh as variable. I want to set several skeletal meshes as array.

[thin panther]

why do you need the make array explicitly for that

just make an variable of skeletal mesh reference, and change it to an array

though you'll probably want a soft ref

[trim matrix]

what does 'soft' mean?

[wild crater]

Do you guys have different naming tendencies in BP compared to BP? You could argue that specifying arguments in your function name is obsolete, but the autocomplete in BP doesn't show you the arguments like it would in C++ so more specific names can be helpful. So I name my function something like GetArmorFromType, whereas in C++ you could argue that GetArmor(type) suffices.

[frigid summit]

hi guys why does the widget still showing event if i called the remove from parent in hud

[frosty heron]

the most obvious reason would be you didn't remove the target widget

[frigid summit]

thats how i removed it dkw it didnt work

[frosty heron]

debug

also make sure u don't have multiple timer widget created

[frigid summit]

you mean print string right?

[rancid moat]

the Get Registered Devices make my game crash
with a "Fatal Error" message on Package
and a "EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000070" error on Launch Game
There's, however, no issue while launching via editor.

I'm not really sure what the issue is tho?
The issue occure because we have 2 sets of Logitech wheels, the G920 and the G25, and I want to set my IMC accordingly., so I get the Product ID to test things.

[frigid summit]

it didnt print anything 😦

[frosty heron]

I can't debug for you from here, you have to figure out what u are actually removing and what actually stay on the screen

[frigid summit]

ok

[kind willow]

I'm trying to spawn a corpse on player's location when they die, but need quick saving/loading to still work on the corpse actor. How do I enable input on the spawned corpse actor? I tried this, but it didn't work

[frigid summit]

the proplem was the delay was in the enemy blueprint i put the delay on the hud and it worked

[lofty rapids]

so memory wise, if i get my game instance in several bp's, is that loaded multiple times in memory ? or bp handles that ?

will there be a copy for every bp that accesses the instance ? or will bp handle the reference ?

[spark steppe]

you will get a reference if you use the get game instance node

and all of those references will reference the same game instance

[lofty rapids]

that's what i was hoping, that it didn't make copies thanks

[lofty rapids]

the references i understand, but if i cast and create a new reference is this going to pile up ?

[spark steppe]

yea that will pile up references, but not game instances

[lofty rapids]

so if i cast to game instance on several objects, this piles up ?

or they can use the same game instance ?

i might need to look into interfaces, i have not got into that yet

[gentle urchin]

The refs pile up

But they all ref the same instanced GI

[frosty heron]

there is only one GI

[lofty rapids]

so it doesn't make a copy and store that again in memory

[frosty heron]

when ever u get, you are pointing to the same instance

[lofty rapids]

ok perfect

[frosty heron]

don't need to worry about a copy of a pointer

[lofty rapids]

so it won't load multiple of the same into memory

[frosty heron]

there is only one instance of GameInstance

[lofty rapids]

same for the player, if i cast in multiple objects it will just load the one into memory

and will use the same for the cast ?

[thin panther]

the casting causing loading causes the default object to be loaded,
there is only ever one, and it is only loaded once, for the duration of play

it incurs quite a penalty with asset references, or barely anything with properly set up classes

[short reef]

How do I disable the tab key from focusing widgets?

[raw orbit]

was there a 2d int vector struct? i forgot what its called, just wanting to avoid making my own if i acn avoid it

Turns out, I had to possess it first :p

[thin panther]

vector2d?

[raw orbit]

well they are floats but i suppose its not a big deal is it

[versed sun]

Actor A has a Hard ref to Material_A
Actor B has a Hard ref to Material_B
Actor C might be Material_A or Material_B
Is there any point to Soft ref Material_A and Material_B in Actor C?
(When I know Actor A,B, and C will be loaded)

[raw orbit]

oh its int point

[marsh pilot]

Currently having a strange issue where I'm trying to get my NPC AI controller to possess some NPCs. The NPC_BP is a character blueprint. Why is it not able to cast?

[versed sun]

Possessed Pawn>Cast to NPC_BP> set Pawn Ref

[marsh pilot]

Ah that did it thank you!

[gentle urchin]

No

[simple echo]

In Unity, you can create an "Empty" game object, which is effectively an actor without a mesh.

There are a number of different reasons one may want to do this, but for me, I am trying to implement a Boomerang mechanic Where the throwable weapon "orbits" around this empty game object.

Does something like this exist in Unreal?

[dim kiln]

I download the project on another computer and some blueprint parts are missing. My version control says there is nothing different. Any ideas what is wrong?

[gentle urchin]

Uobject

Or just an actor, without a mesh

Actor is more convenient imo

Even tho its a bit more overhead

[dawn gazelle]

Different version of Unreal possibly? Enhanced input is a plugin that needs to be enabled too in earlier versions.

[steady night]

this is probably a dumb question but is there any way to hide the variables from ?

from the details

[gentle urchin]

You can hide them under a category atleast

DONOTTOUCH is one ive seen before

[random pulsar]

when i cast to a widget what do i need as a object pin?

[gentle urchin]

A ref to the widget?

Always a ref to the thing

You're trying to cast

Cast is a 'type conversion'

Requires a valid but possibly wider scoped reference to an instance of the object in question

[steady night]

how would i hide it Squize :/?

[gentle urchin]

Category is your best bet. Or c++

[steady night]

hm mkey

[lofty rapids]

You cast "from" something "to" something

in this case a widget reference that you probably made when you created the widget

[lofty rapids]

why do you need to cast to widget ?

you should just use the reference

[random pulsar]

i have some widgets and they are all in main widget,from start they are collapsed,and here i want to enable a specific widget visibility.I always create a widget and this is simple but why to create if i can just enable the visibility of this one?

this way i create a widget , but is not good cuz this means i have 2 same widgets 1 collapsed other visible

of did u mean i create a variable with the type of my widget?

[verbal wren]

I am working on having an AI that will shoot a homing projectile at a target, right now I can get it to spawn, find the closest actor, and go that direction. However the homing is locking onto their feet, often missing, and im not quite sure why.

[frozen cairn]

Is there any way to prevent player bouncing on collision with enemy? And prevent main hero to jump on enemy?

I've tried different collision presets and if I need to use "sphere trace by channel" (for attack) I must use block preset between enemy and my hero.

[barren sapphire]

Hi!
I've an interesting problem waiting to be solved. Please help if you can.
I have a large amount of data saved float variables by tick
when I get those data I have this array:

I have it's time in milliseconds
my goal is to arrange those data to send them in correct time (as it was recorded)

[dry sleet]

You want to sort it?

[spark steppe]

you don't need to sort it

you use a delay and use the time

the delays will fire all at the same tick

and it will probably perform horrible

or you sort them descending, and each tick you evaluate the last element, if it should execute you do that and remove the last element

[dry sleet]

I would just sort the array, set a timer for the amount of ms specified, then pop the first element and repeat, I think.

If I understand the issue correctly.

[spark steppe]

i would just make an replay actor or component, and let it run on tick

after all, it's likely that there's a fixed interval so you can even adjust the tick interval of the actor to account for that

also overhead is quite smol if you just have to check one element each tick

[barren sapphire]

but there is a ctach for this method, in one tick there are many floats

[gentle urchin]

Id just pass the data with the timestamp

Sort it on recieve

[undone knoll]

Is there anyway to call an overlap the second any part of the mesh is overlapped, not just the center point?

[barren sapphire]

yes thank you but I how to sort it on recieve? I need to send those datas on tick to a graph

[random pulsar]

i have seted the coins in game instance and a boolean if the player can jump ,a store ui and debug jumping,it works,now how can i set up buying this things.For ex i will show the player by text how much both cost,but how do i buy it? i mean i compare on the button click event if there is >= coins than the price and if yes ,enable the boolean,if not do nothing?

[gentle urchin]

Sounds about right

[random pulsar]

forgot about the money,i need also to subtract the price after😄

[blissful moat]

heya, I am creating custom spawner for my enemies but I want to snap them to the floor when they spawn. They all have a different capsule size. Is there a way to get capsule size from a class reference?

Something like this

[lunar sleet]

Half height and height are not the same thing btw

[blissful moat]

I'll have to add the capsule height as a parameter in the class then I guess?

I can't access the components in that class

[lunar sleet]

It you want all of them to have the same half height why not just change it in details panel

[blissful moat]

ah no I want every enemy to have a different height

Eh, I'll make a parameter for it 😄

[lunar sleet]

Or trace to the landscape to determine the adjusted spawn location

[blissful moat]

Oh that sounds like a better idea

Hmm damn I still need the capsule size for that

the root is in the center of the capsule

[random pulsar]

i want to represent the text by the jump price integer variable how do i link em here

to change only jump price and see that the text changed

[lofty rapids]

probably bind

you can bind a variable to the text

[random pulsar]

nice and easy hah

thanks

i thought there is another way

[lofty rapids]

ya you can bind it, next to where you would normally set the text in the editor, there is a bind you can click and select the variable

then when you change the variable, it will change the text

[random pulsar]

yeah but i thought there is another way,not binding but in event graph to display the text as integer

[golden kite]

This is a basic question but I can't seem to find the canonical answer. I need a reference to a Level object inside my animation blueprint (for LookAt purposes). The object is a TargetPoint.

I thought the best approach was to create and expose a variable that takes a TargetPoint, and then just grab its world location and pipe that to the LookAt node.

The character (Actor) is a Metahuman, so the animBP is on the Face mesh. I'm trying to figure out where in the BP hierarchy I should create that variable so it can be seen when selecting the charaacter in my Level outliner.

The Character BP inherits from a "BaseClass" Blueprint, since I want this functionality on a bunch of different characters across various levels.

If I create the variable at the "Base Class" Blueprint level, how do I bubble it up to the "Inherited" Blueprint associated with the instance of that Actor in the Level so that clicking on the Actor in the outliner show that variable in the Details panel?

(When I first created the variable directly on the Face Anim BP, that doesn't really show up in editor. This is why I'm thinking it needs to "live" on the actor's BP (or better, its base class)

[golden kite]

Strange. If I try the same thing with a Boolean Variable (Create it on the Parent BP and then expose it), I can see the variable in Details when I select the character in the Outliner. But the TargetPoint object variable does not expose.... maybe I need to use a more generic variable type like Actor and then cast it.....

[frigid summit]

hi i want little help with this i want a thing like 4 enimes of the same blueprint placed in a level waiting and two attacking if the first two died the others can attack can someone plz help me

[viscid python]

The mesh of my character consists of 9 skeletal meshes (all connected via master pose component), if I put 4 of these characters into my map with this setup, performance tanks. Is there any way to optimise this? I only have the model in "modular" pieces, not a single mesh and need the 4 characters close together (it's a squad).

[earnest wind]

does your 9 skeletal meshes have their own Skeleton or they are all based on the same Parent Skeleton?

[viscid python]

They are all based on the same parent skeleton.

(all use the same skeleton).

[earnest wind]

Strange, I never ran any issue when spawning dozen of characters composed with multiple skeletal meshes, you should check the amount of triangles of your assets, one of them might be extremely heavy

[random pulsar]

now i can buy this abilities a lot of times even if i have them,how do i make it so i can buy it only one time?

[viscid python]

I have read somewhere that multiple skeletal meshes for a character cost enormous performance, not true then?

[earnest wind]

It actually cost especially when having a lot of vertices in your meshes but you should not feel it when spawning a simple squad of 4

[brazen pike]

Make an array of strings on your player (or where ever it makes sense) which is a list of skills that have been bought. When you buy the jump skill, add the string "Jump" to the array. Then when the widget is constructed, check to see if "Jump" is anywhere in the array of strings. If it is, then don't let them buy the skill again. If it isn't, let them buy the skill.

[frail onyx]

Anyone know how I make it so only one instance of the actor can be slotted at a time? The problem right now is if one is already in and i move my cube into the collision range and then back out it thinks that the first object left and lets me put another in

[viscid python]

What would be a lot in that case? All meshes together would be about 15.000 triangles.

[random pulsar]

ooooh sounds like something new to me ,nice ,what videos should i check in youtube to understand this?

[brazen pike]

Have a check to see if an item is slotted and if something is, don't let anything else be slotted. You seem to already have a bool "IsGrabbingObject", why can't you use that?

[brazen pike]

You can probably find dozens of youtube videos about arrays.

[frail onyx]

i tried something like that where i make a branch to check if an item is slotted and if so i cant put another item in the slot

but the problem is if i move another actor into the overlap collision and then back out it thinks i took the first actor out allowing me to put a second item in

[brazen pike]

Then have the variable be a reference to the item itself, allowing you to check what item just ended overlapping. if it's the same as your variable, execute the logic. If it isn't, do nothing

[frail onyx]

do u know how how i can get that reference?

[earnest wind]

Is it only when pressing play or even in editor when dragging Models to your scene?

[viscid python]

Only when pressing play. Otherwise I get 120fps.

[brazen pike]

At least, I'm assuming this is what you are trying to slot in

Whenever you overlap with the item, thats the reference

[earnest wind]

Check your logic to see if you thick something you should not, maybe something is called every frame

[random pulsar]

did i add it correct?

[brazen pike]

And it only happens when you have multiple characters?

[frail onyx]

ok, im not exactly sure how to use that though/what do with it to make it check

[earnest wind]

Because If you can afford a squad in your scene without playing It should have no diff when playing

[viscid python]

At least I can't see the performance dip with a single one 🤔 It gets wors with more, though.

[brazen pike]

You probably want it to be on the player's Blueprint so that it always exists. If you close the shop widget and the array is on the widget, then the array will be empty the next time you open the shop

[brazen pike]

What do you have running on tick with them?

[viscid python]

That sounds logical. Hmm. I don't get it. The blueprint I use for the characters is supposed to be super optimised. And it runs faster if I only attach one mesh, then there is no performance hit for four characters.

[viscid python]

They have an AI, the one from the Third Person Shooter Kit 2.1, it's a well-known asset that should allow countless AIs on screen at a time.

[brazen pike]

Make a variable that is an actor object reference (assuming every item is an actor). When you try to slot a new item in, get your variable and check if it is valid. If it isn't valid, then you have nothing slotted in. If it is valid, something is slotted in.

When you are going to remove an item, get the variable and check if the item you are trying to remove is the same as the variable. Use an = node.

[brazen pike]

try disabling the ai

just to see

[viscid python]

Alright!

[viscid python]

Same result but the characters just stand around like puppets now of course.

[brazen pike]

You should start checking the tick of anything that's running

or, you can slowly delete things until you find your answer

You can also use something called the session frontend, which will tell you exactly whats causing the issue. But it might take a second to learn how to use it

[viscid python]

Well it must be the models, as disabling the AI didn't have any positive effect on the performance.

So I will probably try to find a better asset.

[brazen pike]

Remove the skeletons from them

just make then an empty asset

If its the models, the fps will be normal

maybe the animations are problematic. You'll have to simply disable things and check if the problem stops happening

[slate fable]

still trying to create the dice roll mechanic if anyone got a minute 😄

[gentle urchin]

Is it problematic?

To make?

Rand(0,sides)?

[slate fable]

@gentle urchin yea difficult for me trying to use a d20 in the 3d space

[magic gorge]

I think he means actual physical dice

[gentle urchin]

Oh like that

[slate fable]

Wanting to calculate it

[gentle urchin]

Calc? How so?

Wouldnt they just fall as they fall?

[slate fable]

like physically roll a dice and have the result calculated vs another roll

[magic gorge]

I know someone used linetrace or normals i dont remember how

to see which face was

[gentle urchin]

Yeah

[slate fable]

premise of the game is to roll a d20 then whatever the result is, is what dictates what happens next

[gentle urchin]

Or add small colliders

To each side

Whichever is down, mirrored

[slate fable]

thats a good idea 😮 might do that and see if it works

didnt know if there was a way to get all faces and do a calculation on a print string

[brazen pike]

I'd be tempted to do it backwards. Predict the result then make the dice show that

I suppose there'd be an obvious point at which the numbers change

[slate fable]

@brazen pike would do that but it takes the visible mechanic out

[gentle urchin]

Would be hard to make that look natural wouldnt it ?

[slate fable]

yeaaaa lol im going to try the colission boxes on the faces and see how it does

[magic gorge]

https://www.youtube.com/watch?v=iqscP1aRmbE

[gentle urchin]

Small ones

[magic gorge]

this uses collision

[brazen pike]

hmmm if it spins fast enough, blur the material? then switch the numbers?

[gentle urchin]

Half the area across

[gentle urchin]

Well that could work

[magic gorge]

just search you find, even if its unity you understand the concept

[slate fable]

I've watched a few tutorials but none of em explain it very well

[gentle urchin]

You can also ofc just hide it under a cup or whatever

[slate fable]

its a tabletop game

[gentle urchin]

Yeah

Dont you use roll cups?

[slate fable]

nope 😛

[gentle urchin]

Pff

Gotta use cups

Avoids cheating

[slate fable]

Lol

[gentle urchin]

(And dices running off the table)

[brazen pike]

Hmmm calculating it mathematically using the rotation of the die would get tricky once you get to higher number sides

[slate fable]

I could use a dice tower I guess 🤔

I want it to feel as natural as possible

[gentle urchin]

Ah yeah, those too exist

Rarely see them

[brazen pike]

Invisible colliding boxes on each face? When it finishes rolling, do a raycast down to hit the top collider and check which side is facing up

might be a little more authoring but could work

[gentle urchin]

With colliders you dont need to raycast

Its simply whichever is still colliding

When it stopped

[slate fable]

so do a collision raytrace at each face using the bottom one to predict the opposite side (top number)

[brazen pike]

yeah but it might be a little rough to get the size right

[gentle urchin]

Depends on the size of the dice

[brazen pike]

I know I'd roll it and have like 4 sides colliding lmao

Id do half the width

[slate fable]

[gentle urchin]

If need be

Or you can ofc just

[brazen pike]

yeah, that'd work

[gentle urchin]

Check its rotation on stop

Should be an easy lookup table

20 rotations

[brazen pike]

I can see that getting so tedius though

[slate fable]

data tables?

[gentle urchin]

You automate it 😆

Auto roll untill tmap has 20 entries

[brazen pike]

didnt even think of that

[gentle urchin]

Im mostly kidding

[brazen pike]

I dont think I've ever automated anything so have no idea whats viable and what isnt lol

[viscid python]

That might be it, interesting thought!

The animations I meant.

[frail onyx]

i tried doing that but it doesn't seem to work, not sure if i did it correctly

[ornate trail]

Not exactly sure why this happens but if the control pitch starts negative the whole things lerps to -115 instead of 10

gimbal issue maybe idk. Basically when doing this ability I just want the pitch to come back up incase it was too low
