[willow gate]

Hey friends. Anyone know of some comprehensive Android/iOS tutorials? I have found several scattered tutorials, documentation and other resources for making mobile games but I wondered if anyone here knows of any good tuts that cover things like interfacing with logging into Google play and the apple store and microtransactions.

[sand yacht]

looks like this is exactly what I need, however is there a way to use this in blueprint?

[lunar mulch]

Hey guys, im brainstorming some code idea where i want to Blend in a Visual effect as the player reaches a stamina Threshold. Made a prototype using Timelines where the timeline starts to blend in the post-process when stamina is below 50%. Blends out when hes above 50%.

This still requires me to set an arbitrary time for the timeline, so its basically just spitballing it.

Because of this i have a feeling like timelines are not the right approach for this type of stuff. But they are great for Blending in and out values slowly over time. Are there other Nodes can blend in values relatively simple similar to timelines?

[rugged sonnet]

Any idea why I can't get "Set Material Instance Vector Parameter"?

[versed sun]

you can set the timeline length to 1 and then before the timeline plays you can set the Play Rate
this setup would take 3 secs to finish the timeline , even tho its length is 1
not sure if this helps

[thin panther]

yeah there's built in functionality, or easy to access plugins for http post and get calls

you might need a secondary thing to get local coordinates.
also note you're probably going to have to draft a privacy policy for collecting geolocation data like that

[lunar mulch]

Hey thank you for the idea, this gives me some food for though! 😉

[undone sequoia]

guys if I am multiplying value for example speed by delta world seconds , its result is always very different as delta world seconds tick is always different how keep this number as smooth as I can?

because I display speed and see 58 60 56 60 62 50

its jumping like crazy

sometimes is delta worlds 0.02 0.03 0.025

[thin panther]

show what you're trying to do

you absolutely want to multiply something like speed by delta seconds

[undone sequoia]

I am printing speed of plane and i dont want its speed to be connected to FPS so I need multiply it before implementing

if I dont use speed * delta ms then someone with 20 fps will be more slower than me

but if I use delta ms * speed then everyone has same speed every frame

[thin panther]

yes exactly

[undone sequoia]

but outputs from this multiply is crazy you see 64 64 59 59 64 63

it cant be like this 😄

when you have constant speed

because my delta ms looks like this

its everytime different value

idk how to make it smooth

[sweet silo]

hi there how would you create a routine system with characters moving at specific times throughout the day ? thanks !

[thin panther]

a frame will take differing amounts of time to execute

that's just how it is

though in your above example im not sure why you're multiplying the result of the delta by 100

you definitely don't want that

[undone sequoia]

because its slow without it

[thin panther]

so increase the speed

[undone sequoia]

okay lets say I am not multiplying it by 100 , then result is this with constant speed, also very bad numbers it solve nothing 😄

problem is definitely not *100

[lunar sleet]

Probably an event dispatcher that is called at specific times of the day. You’ll need to implement some form of time system

[thin panther]

can i ask what your fps is?

[lunar sleet]

Isn’t it speed = speed * delta + speed? Can’t rmbr

[sweet silo]

ok cool yeah i see i already have a time system but i don't know how compatible

but thanks !

[thin panther]

nah.

speed is like you're per second amount of units you want to travel.
you want to multiply that by deltatime, so you get the number of units for that frame

[lunar sleet]

I mean you could use an event by timer to check what the current time of day is at certain intervals, and call the dispatcher if it’s above a specific time

[thin panther]

i.e. my frame took 1/50 of a second, so give me 1/50 * speed

[sweet silo]

great idea i'l do that

[lunar sleet]

Ah so just multiply it to make it not be tiny then?

[thin panther]

or just increase the speed :P

[lunar sleet]

Is it possible to do this with timelines? I’m having issues with them when fps drops rn

[thin panther]

the issue here though seems to be some very unstable frame times which hunts at poor optimization

[thin panther]

i mean you can access the frame delta anywhere with get world delta seconds

[lunar sleet]

Well on my end I’m using a Niagara 3D Flip template and let me tell you, that thing is fricken expensive lol

[thin panther]

whether this would work with your timeline implementation is improbable at best

[lunar sleet]

So what are my options? The timeline controls x and y values over a certain amount of time, not sure how else to do that reliably

[undone sequoia]

60 locked

hm idk what use there ah

[pulsar vigil]

Guys another weird question what get should i have here to cast successfully to this widget ? im trying to cast an animation blueprint to a widget lol maybe its insane

[lunar sleet]

You need to watch the blueprint comms video pinned here. Also that looks like an anim bp you’re trying to cast to, not a widget, and generally, you want to cast from the ABP to other stuff not the other way around.

[trim matrix]

To cast to a widget you need to either store its reference once it is constructed or use the (expensive) node https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Widget/GetAllWidgetsOfClass/

[pulsar vigil]

i want to use a play rate variable in the ABP to control opacity of an element in the widget, my cast is at the right place normaly, its to use an event dispatcher created in the anim bp

[lunar sleet]

He’s not casting to a widget tho

[trim matrix]

they could have named their widget like that 🙆‍♂️

[lunar sleet]

And idk what “my cast is at the right place normally” means

[lunar sleet]

If they named a widget ABP, I’m going to go to another channel lol

[pulsar vigil]

lmao

[pulsar vigil]

my cast is here to set the variable and use it to target the event ? does that make sense ? thats a real question im lost lol

cause that how i operated until now and everything work

[trim matrix]

is ABP_ShowNPC a widget?

[pulsar vigil]

no its not lol

Guys

I said i want to use a variable in an ABP to control opacity of an element in a widget via an envent dispatcher

i just need to know what should i get to cast succesfully

[lunar sleet]

ABPs are not meant to be accessed this way

[pulsar vigil]

i sure trust u cause i have some weird idea since i m a nooby but is it possible ?

[trim matrix]

they can be tho but why do you need to do it throught the anim bp?

that is the big question

[pulsar vigil]

are u kidding me i said it 2 times already

[undone sequoia]

when I fix fps of editor its fine because delta world seconds are always same but when fps are not fixed then its problem 😄

ah

how are people solving it?

[trim matrix]

they aren't meant to be used in this way

[lunar sleet]

Sure, it’s possible. I can’t rmbr how, but there’s some weird detour you gotta take

Or you can just do it right 😀

[pulsar vigil]

ok, do u know the way ?

[gentle urchin]

Get anim instance

From the char , returns the animbp

[pulsar vigil]

thats look like its a way but it stipulate a context i have to say i dont know how to "from the char"
im sorry it look basic but i dont understand the exact way

[gentle urchin]

You can see the implementing class below the function name

Thats the context you need

Character is a native unreal class that many utilize

For their player characters

[pulsar vigil]

i mean i may be slow

[trim matrix]

wrong node

[pulsar vigil]

whats then node name bro 😄

[trim matrix]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Components/SkeletalMesh/GetAnimInstance/

[pulsar vigil]

Oh so i need to put the skeletal mesh targeted ?

[trim matrix]

you need to obtain a ref to the skeletal mesh, yes

[pulsar vigil]

jesus

that look like the wrong way indeed

[trim matrix]

isn't there a way to get directly the anim instance straight from the character actor?

[gentle urchin]

I thought so but maybe memory fails me

Im not doing detour like this anymore so idk 😂

[trim matrix]

there should be smh

[trim matrix]

you can do get component by class

[pulsar vigil]

maybe can help

[trim matrix]

don't use that node with the context input

[pulsar vigil]

im probably doing atrocity

[trim matrix]

idk what that context even is suppoused to be

[trim matrix]

👆

[pulsar vigil]

im forced to get a skeletal mesh here ?

[trim matrix]

.

[lunar sleet]

You asked for this

[pulsar vigil]

ok, just for common knowledge u generaly dont use variable set in the abp in other bp ?

[lunar sleet]

Correct

Not the right place/way to do that

[pulsar vigil]

thx i will find an other way

[gentle urchin]

AnimBP is a slave

To the Character

Generally not used to provide any statefullnes to anything else i guess

[faint pasture]

Yes, think of an animBP like a shader

it SHOWS the state, doesn't decide it

[pulsar vigil]

perfect thx for the valuable information

[lunar sleet]

Good way to look at it

How’s the intercooler realistic physics system coming along ?

[feral ice]

How do i get the angle between my characters forward vector and my camera direction?

[faint pasture]

It's coming. Did you know that the math behind thermodynamics is pretty complicated? lol.

[faint pasture]

I think there's an angle between vectors node but you can also do a dot product then an atan

[lunar sleet]

Haha, yes I had an inkling

[feral ice]

yeah that gets me so far but i need an angle with - or + "How do i get the angle between my characters forward vector and my camera direction and if the players camera is looking at the left of the player it should be a negative angle? " Sorry didnt fully explain my problem

[feral ice]

i think you mean acos :P

[faint pasture]

negative implies there's an axis to rotate around

what axis are you using?

[faint pasture]

I'd check sign of dot product between camera.forward and character.right for that

[feral ice]

well im not there yet. I have been using find look at rotation and then substracting the z value with players rotations z but that didnt work

[faint pasture]

or you can just transform rotation to get the camera rotation relative to the char and do whatever you want with the pitch and yaw

[feral ice]

ah yeah true

[thin cradle]

hey, I have an actor base cpp class with a scenecomponent root created in it
I also have a blueprint inheriting from that actor class, as well as several blueprints inheriting from that first blueprint
I can change the type of the root component in the first blueprint, but I can't in the other inheriting ones, is there any way to make that editable in childrens?

some of my child blueprints rely on the root being a primitive with collisions but some of them are gonna have meshes and others just collision shapes, rn the only solution to that is for all BPs to inherit from the original cpp class but then I don't have a base bp class to set common variables and components in

[remote meteor]

is EditAnywhere used on the UPROPERTY specifier?

[thin cradle]

yup

like I said, the first BP class I can modify the root on but not the other BP classes that then inherit from it

oh also modifying the root is weird, I have to click on it and change the component class, I can't just drag an existing component onto it

it either detaches the component or doesn't do anything instead

[lunar sleet]

Children are usually allowed to change the default value not the type of variable

[thin cradle]

weird that it'd work when inheriting from the cpp class but not from the bp class

weirdly enough too placing a get root in the bp lets me change the type which doesn't sound intended https://i.imgur.com/nDKbHYR.png

[lunar sleet]

Why would you do this to begin with, what’s the use case?

[thin cradle]

I need a base class for my "puzzle objects" where I'll handle common mechanics ie saving data for that actor etc
I also have multiple type of puzzle objects that inherit from it, but they're all pretty radically different
some of them have a mesh, and that mesh needs to be the root because they're physically simulated and change scale dynamically, which for some reason only works if the physics enabled component is the root
some other don't change scale and aren't physics enabled, being either just static objects with collision or triggers, etc

back when all my blueprints inherited directly from the cpp class it worked fine but meant anything common to all of them needed to be implemented in cpp or be duplicated a bunch

[split rose]

hey anyone with a bit of free time to help me out on a small thing

i got a reset level function and im storing the player transform and camera rotation into the game instance, so when reloading the level the player stays in the same place, but somehow the camera rotation just doesnt get applied properly

any idea why?

[thin panther]

it might be due to the controller rotation

how are you setting the rotation back

sometimes, in certian cases controller rotation is always overriding it

[split rose]

im doing a set world rotation inside the player blueprint

[lunar sleet]

Can you make your base class include the static mesh with nothing in it as default and just change the static mesh?

[thin cradle]

wouldn't that mean any inheriting actor that doesn't need a mesh end up with just an empty static mesh component?

can that become a problem in any way

[lunar sleet]

Not really

[thin cradle]

I'll do that then

[lunar sleet]

It’s not tied to any assets so not rly expensive

[thin cradle]

there's no overhead from a staticmesh with no mesh? is it just treated as nonexistent or smth

[lunar sleet]

If there is, I’d imagine it’s negligible if it’s got no asset hard ref

[thin cradle]

oh also while that solves the type changing thing I still can't change anything on the component through the details panel

[lunar sleet]

How so

[thin cradle]

even with "editable when inherited" is on

[split rose]

https://blueprintue.com/blueprint/j4v-p0n7/

[lunar sleet]

Did you recompile both?

[thin cradle]

yup

nevermind fixed it

my earlier workaround of setting the type through the get node broke it

resetting the type in that fixed it even tho it's the same type

oh and I can change the type in child classes now too. go figure

[thin panther]

yeah, you'll want to be using control rotation, not set world rotation

or unposess, set those, then repossess

[split rose]

alright i'll try these thanks

🙏

[thin cradle]

although I need to cast to their respective type whenever doing anything not covered by scenecomponent for some reason

yeah I'm just gonna make the default root a mesh

[lunar sleet]

Prly needs it to access the specific functionality of said component

[thin cradle]

yeah it's just weird that the same blueprint where I already specified the current type of the root still needs to cast and isn't just aware of that

if it were all cpp I'd get it but BP tends to abstract away stuff like that

[trim matrix]

can i damage an actor?

[gentle urchin]

Sure

Apply damage

[zealous moth]

what do i need to do to report all my hits through several layers?

during the trace, i see a green

but i want to report all hits throughout

huh i guess trace by channel doesn't do it

but trace by object does

interesting

[thin panther]

all traces stop at the first blocking hit

[elfin hazel]

One thought would be to have a cooldown time. Timestamp when the player enters. If timestamp + cooldown < current time, then the logic can execute.

[thin panther]

multi traces will hit any amount of overlaps, but will also stop a the first block

[tidal marlin]

Hello. How do I fix the cancellation of Input at the moment when I click on the interface? As for example i hav this input and when i click on widjet buttons in my viewpot it cancle.

[zealous moth]

not true for objects if you do complex

[thin panther]

LineTraceForObjects will perform a collision trace along a given line and return the first Object the trace hits that matches one of the specified Object Types.

[trim matrix]

im trying to create an exploding veichle that i can shoot but it doesnt seem to take any damage

there is something i have to use like a collision box?

this is my current bp

[split rose]

you'd probably run that event whenever the bullet hits the car

[thin panther]

where are you applying damage though

that's receiving damage, which is great

but you need to apply it

[split rose]

also this ☝️

[trim matrix]

i think i know, my weapon hits only actors with a tag

[thin panther]

(just show the code for your damage)

[trim matrix]

i followed smart poly's zombie game tutorial

[split rose]

yeah if the object doesnt have the zombie tag it wont recieve damage

[trim matrix]

im working on that

[faint pasture]

multi line trace

[zealous moth]

I did do that, but it only works if you muti line trace (complex) by objects, not channel

[split rose]

maybe do another line trace with the same input that checks for the tag "destructableObject" or something and then apply the damage

[thin panther]

no?

read again what the multi line trace does

it returns still after the first block, but returns every overlap between

[split rose]

(my unreal knowledge is still small so I might not be as helpful) @trim matrix

[thin panther]

so set the trace channel on those things to be overlap

[zealous moth]

I dunno what to tell ya, i'm doing it

and it doesn't want to return it

[thin panther]

yeah that's not great

for a tutorial

[trim matrix]

i needed something to start and i wanted a game about zombies so, its at least something

[zealous moth]

@thin panther

it's all in there

but after first hit, it will not report the next hit

[trim matrix]

i've been using ue5 for 5 days so anything i can learn is useful

dont worry

[thin panther]

you still aren't reading what I'm saying 😭

a multi trace stops after the first blocking hit.
it reports all overlaps between.
so the objects in the world must overlap that trace channel.

you haven't shown me anywhere you doing this

[zealous moth]

I don't get it, why would the channel differ in results to the objects?

I literally plugged in the same params

and got different results

[split rose]

@zealous moth make the objects overlap the trace hit not block it

[zealous moth]

ah~

ok, I get it now

[lunar sleet]

Interface means something else here, just fyi. What key are you using for that input action?

[zealous moth]

well excuse me for not reading it right the first 5 times

ty

[lunar sleet]

Tbh I didn’t realize a line trace can detect overlaps, that’s nice

[thin panther]

no problem, if you result in issues like camera clipping from overlapping visibility, you may consider a custom trace channel for that

[zealous moth]

yeah i knew that part, but I completely forgot that most SMs block the channels all the time

so tracing by objects makes more sense now

[lunar sleet]

Custom collision channels/objects are also an option

[thin panther]

absolutely

though i'd only have one

and apply a series of modifiers based on hit object, probably via gameplay tag

[versed sun]

hmmmm...

should the amount of BP nodes you have on the graph make a difference on FPS, but only if that window is open ?

[dawn gazelle]

I've noticed that it can.

[versed sun]

I have a large BP, and if that Graph window is open , i get 10-20 fps
if the windown is closed/ on a different graph, FPS is 70

can a BP be "too big" ?

[dawn gazelle]

Probably not. Like, if you were to organize that into separate event graphs, then you may not see the same problem.

[versed sun]

or Convert to Function

[lunar sleet]

Usually better to break it down into functions if it gets too big

[versed sun]

i already have a few functions

[dawn gazelle]

Collapse nodes 😄

[versed sun]

ewwww

[lunar sleet]

I’ve seen people get lost in their own code cause they collapsed

[lunar sleet]

Other than sluggish response which can be annoying to code in, editor fps doesn’t really matter

[versed sun]

i get local variable errors when i collapsed things

[elder lodge]

collapse them differently
make sure the right varaibles are either scoped right or input/output correctly

don't collapse willy nilly

[lunar sleet]

Or just use functions/macros and call ‘er a day

[versed sun]

yup, didnt know if there could be an issue with too many functions

was driving me crazy that sometime when i play its 15fps, and sometimes its 70

[elder lodge]

Before I get too into the weeds on a zero-g platforming feature; for "magnetic boots" that will let me walk on any surface, what are the nodes that will help me with this? Probably some raycast out of the feet, right? Or should I also look into "welding" them if it was, say, a movable plane?
I just know if I have boots imparting force, I'll need extra logic if it's on a moving surface.

[versed sun]

Did you try the Directional and Planet Gravity plugin?
no clue if its any good...

[runic pagoda]

Any idea on this one? Pressing T triggers the animation no problem, but calling it from the Event -doesn't- play the animation.
The node still gets triggered (I put a breakpoint there, and the montage node gets triggered) it just doesn't play the animation, but pressing T does play it. I see no functional difference between the two though.

[lunar sleet]

Idk if you can extend that in bp but try #multiplayer

[lunar sleet]

Same goes for you

[dawn gazelle]

It's not a blueprintable class.

[elder lodge]

i've already got gravity implemented to my satisfaction so far, it's the flying/walking transition which I may have to rewrite

[dawn gazelle]

Put BlueprintType, Blueprintable in the UCLASS specifier, but i'm not sure how useful it will be as it doesn't look like anything within the C++ class is exposed at all to blueprints.

I suppose if you have your own functions and variables exposed in your own C++ subclass you can do some things with it in blueprint.

[lunar sleet]

Is that a function you were showing with delays in it?

You could use a bool check at the start of it

Well, so you want the sounds to queue after each other?

Have you tried #audio for this? There might be pre-built or obvious solutions

What is this protection you are talking about, define precisely what you want to happen if a player quickly makes 2 overlaps back to back

And why are you allowing this instead of doing what #audio suggested by using a distance check

Depends, I’m having a hard time picturing your use case

Alright

So you want to account for those players that go back and forth in the bunker’s door?

[narrow pendant]

how do I get all actors of class including child classes? I've got a BP_TreeBaseClass and multiple child BPs. I would now like to find any of those child BPs around an actor

[lunar sleet]

K well delays are usually the wrong choice. If you want something you can stop, other than using a coroutine plugin, your best bet is a timer by event

[lunar sleet]

Just sphere overlap or whatever you’re using, cast to the parent class

[proven garnet]

Hey I need some guidance from a nice person. I'm trying to update the score in the bottom right corner of the screen when I walk over the coins. I have set the coins to destroy on overlap with the player character but I can't seem to connect the coin BP to the UMG BP in any way. Just getting errors. I tried googling casting but tbh I don't really know what to ask for to get a good google result.

Appreciate if anyone could check this out and see what I can do to get this to work. I'm probably just missing something easy. Thanks a bunch!

[narrow pendant]

I see, thanks

[thin panther]

https://youtu.be/qc5WpNq7RFg

[cyan spire]

took me hours to understand why "cast to" does not work, figured out it does not actually cast into another blueprint but casts FROM another blueprint ffs damn naming scheme, im not a programmer 😁

[lunar sleet]

Neither of those is accurate

[narrow pendant]

oh there's a sphere overlap actors node, never saw that 😄

[thin panther]

i think you're confused.

because both of those aren't true

a cast is type conversion

taking a reference and seeing if it is of a more specific type

[lunar sleet]

A cast checks if a ref is of a certain class and if successful allows you to access its innards

[thin panther]

:P

[lunar sleet]

Yeah, add a for each loop on it

[narrow pendant]

yup yup I got it 🙂

[dawn gazelle]

https://tenor.com/view/fishing-rod-snap-cast-fish-fail-gif-17119887

[thin panther]

because it's called a cast

why rename the fundamental thing, that is used across languages, because people interpret a meaning it never had

[lunar sleet]

This is why I don’t like using this definition

[narrow pendant]

🧙‍♂️ because wizards

[lunar sleet]

Yeah, the hogwarts people will get confused and think it’s a magic wand

[narrow pendant]

"cast is a type conversion" did not help me back when my understanding of programming was in the negative digits

[lunar sleet]

Type conversion can make a rookie think you can turn any ref into some other bp

[thin panther]

so many people do it, because they jumped into a programming language without programming knowledge, which leads to false assumptions.

it's a common mistake, but pretty exclusive to unreal

[cyan spire]

Oh my god what have i done to this channel at night 😆

[thin panther]

yeah a type check is a better way to put it

[narrow pendant]

"Is This A and Does It Really Exist" is how I think about it (as in is it instantiated, because you might have the correct type of object but it might still return none)

[lunar sleet]

For one , use a cast instead of == actor, and second, I don’t see a call to change the number anywhere in your overlap

[thin panther]

that would be a good middle ground.
i still don't like renaming it tho 😭

[cyan spire]

Laura again, i thank you for your help, this is the one that actually makes sense for me

[thin panther]

it just returns a more specific pointer. its still pointing to the same thing

[dawn gazelle]

https://docs.google.com/document/d/17bEGQEC1_G5KQKAI3_ixbe4S0BIulEH5w4qS9b7fuqc/edit?usp=sharing

[lunar sleet]

A Google doc? Did you make this?

[dawn gazelle]

Some time ago, yea <_<

[thin panther]

Becomes also suffers from the issue that calling it type conversion does, where it also leads to the assumption that anything can become anything

[proven garnet]

I've tried to do it like this but I just don't understand how to get the coin BP to talk to the HUD

[lunar sleet]

Only issue I have is on mobile it seems like the picture resolution is garbage 😀

[cyan spire]

Holy, half discord is discussing about a single name, this wasn't my intention

[thin panther]

tbf the explanation is only 2 lines. the rest of it is practical examples, debunking specific examples of what it isn't, and an faq :P

[stuck sentinel]

how can i fix this? ive only been using locomotion until now

[narrow pendant]

it's a controversial topic just like math channels ducks

[lunar sleet]

Where is your widget created, in the hud bp?

[thin panther]

it's a pretty useful discussion though

[stuck sentinel]

its only when i run

[cyan spire]

As a beginner i gotta say naming scheme is what makes it extremely hard for me to get most of the things, and people say if you had a programming background it seems logical. But for me it does not

[proven garnet]

Yes, I have updates for health and ammo also but right now want to figure out score.

[lunar sleet]

Looks like a collision thing, did you move your capsule down or something ?

[thin panther]

unreal is a hard adjustment especially coming from nothing, indeed

[cyan spire]

Can't often guess what it would do, even with the most remote explanation i could come up with, it often has nothing to do with it

[narrow pendant]

most things are only half as scary as the big fancy word it's named after make them seem

[cyan spire]

exactly what i mean

[lunar sleet]

On overlap, get player controller, get hud, cast to your hud bp, call the function - provided this is not a multiplayer game

[narrow pendant]

I've struggled with understanding what a cast really is for a long time too I think it's a rite of passage for us non programmers 😄

[cyan spire]

Biggest problem was for me to grasp that there are multiple (like hundreds) of nodes which sound the same, have technically 80% of the same function, can be only used for certain things

[lunar sleet]

Blueprint comms video is the only thing that cleared up for me, mind you I hadn’t read Datura’s blog back then

[proven garnet]

Not multiplayer, just learning! Thanks! I'll try that, hopefully doing it the right way.

[thin panther]

an important thing to always keep in mind with unreal is that it's a AAA engine. a lot of the stuff, if you're just jumping straight in assumes experience.

[lunar sleet]

You’re not in Roblox anymore 😀

[thin panther]

the official guides for beginners and such help simplify that, but a lot of folks don't even know they're there

[tardy prawn]

i implemented an interface in a parent, then in a child i see that one interface function is grey color (function), and other is yellow (why, what is this) ?

[proven garnet]

Haha I'm too stupid for this. I don't know how to do anyof that. But thanks. I think I'll just watch some other tutorials on other stuff..

[lunar sleet]

What do you mean, I gave you the exact nodes

Just type

[thin panther]

they gave you all the nodes

[stuck sentinel]

there is no collision its just samples i downloaded

[thin panther]

damn beaten to it again

[lunar sleet]

They ? 😀

[stuck sentinel]

cant i make it not play the running animation during a y velocity between 0-100

[lunar sleet]

Did you move the capsule?

[stuck sentinel]

no i did not move anything

new project im just following a tutorial

[lunar sleet]

Follow it again from the beginning

[stuck sentinel]

he has the same issue but he doesnt show it

[lunar sleet]

Lol

That’s tutorials for you

[stuck sentinel]

thats why i came here can anyone her

help

[cyan spire]

Honestly, i learned stuff like 3DSmax,Photoshop,Vegas,Premiere,Illustrator,Painter (at release), and did custom models, animations and mods in general for CounterStrike:Source when i was 14 in 2009. But actually using UE with zero coding experience is the biggest struggle i ever had in my life learning anything.

[proven garnet]

I mean I don't know how to do that. I assume you mean here. But I mean going from this to what you said is like a couple of hours of digging through documentation. I've got like 20 hours into UE.

[lunar sleet]

Go back and read my message thoroughly

[stuck sentinel]

is two years enough to stop following tutorials and courses and instead start problem solving and googling your issues

[lunar sleet]

2 years?! You’re 1.7 years overdue

[stuck sentinel]

what do you mean

is two years too much or too litte

[thin panther]

You really want to tackle some of that coding experience. Learn some fundamentals

You can't use bp without em. It's a programming language

[lunar sleet]

I mean you should mostly stop following random tutorials that are not peer reviewed within the first 3-4 months

[blissful grail]

Too much. You're in tutorial hell. IE - your progress/growth is massively stunted.

Just build stuff

[cyan spire]

Im 700+ videos of Wadstein in, i guess im gonna do that when im through with him

[blissful grail]

Don't care for perfection

Struggling is how you learn

[lunar sleet]

Random tutorials and MatWadstein tutorials are not the same

[stuck sentinel]

yeah i am problem solving

[lunar sleet]

His channel is one of the exceptions ^

[stuck sentinel]

why is the guy still walking in the air thats not perfection

[minor dew]

Does anyone encountered here a bug when reparenting a user widget revert back to the previous parent after relaunch?🤔

[lunar sleet]

#umg for widgets

[stuck sentinel]

no no you guys got it all wrong i havent been two years on unreal im just asking in two years time is it enough to stop following tutorials and courses

[proven garnet]

I'm drawing a blank. I've read your message carefully now but yeah. Maybe I should do some other tutorials. I don't know.

[lunar sleet]

Stop with the tutorials lol

[proven garnet]

I think I need tutorials, I'm very new

[narrow pendant]

learn.unrealengine.com

no youtube

[lunar sleet]

What you need is reading comprehension and more than 30s of patience

I’m going to tell you how to do this again

Pay attention

If this overlap code is on your coin, delete the player char node, the == and the branch

[thin panther]

You don't really want to be following tutorials still after like 6 months maybe

You should ideally be able to start learning in other forms

[lunar sleet]

From other actor cast to your char bp, then on success (not failed pin the other one) get player controller, get HUD, cast to the HUD bp, then from its return value call the function that increases your coins

Follow these instructions to the letter

“More tutorials” is rarely ever the answer

[cyan spire]

Not wanna act like its a good idea but would be awesome to have a newbie bp channel in this discord where we can discuss the most basic bottom stuff everyone should really know and one channel for actual questions

[lunar sleet]

#ue5-general

Or here, it doesn’t really matter

[feral ice]

is there a costum switch on where i can switch on costum values. Like if i have 10, 25, 30 and i have value 10 it should be the first output. What am i looking for?

[lunar sleet]

You mean custom switch? Maybe like a select?

[trim matrix]

https://media.discordapp.net/attachments/728552296908193843/1173677065703268432/image.png?ex=6564d2f2&is=65525df2&hm=4ae26bf967e91c5a3f6b77be1a162f8b4657a933e8f02bdf123d8546387d0917&

wtf is this code

[lunar sleet]

I’d prly put it at the beginning of the function. Promote the handle to a var and check if it’s valid. If not, run the timer, if so, clear and invalidate it

[trim matrix]

It apparently outputs 2/3 somehow

I'll test the shit

[proven garnet]

Something like this?

[blissful grail]

I don't believe that it removes 2/3rds. It removes more.

[lunar sleet]

What does the warning say

[blissful grail]

Just hover over the node and there will be a little button you can click at the top right of it.

[lunar sleet]

What class is your UMG HUD made from then? 😁

[proven garnet]

Widget Blueprint

[lunar sleet]

Test and find out what works best

[dawn gazelle]

What class stores your UMG Player HUD reference you want to use? In what blueprint did you create it in?

[lunar sleet]

HUD class is supposed to extend from HUD

Np. Use branches not flip flops

[blissful grail]

Ah - maybe that is messing with it then.

[lunar sleet]

Click on the node, hover right above it

You should see an ellipsis

That’s not what dyslexia is but ok

I believe it means you read blueprint as blpreutni or such, you can google to find out for sure 😛

[trim matrix]

you both don't know what dyslexia is

[lunar sleet]

Hence the disclaimer

[noble ledge]

Is it possible to set defaults to a BP struct somewhere?

[trim matrix]

defaults tab

in the struct

asset

[lunar sleet]

You can try going to your hud class that’s not a hud, hit file, reparent and select HUD. That might fix your problem, unless of course you put stuff in it that’s only meant to work in widgets, in which case you’re going to need to redo some of this

[noble ledge]

Ah ok thank you!

[blissful grail]

I forget the exact specifics - I'm not in BP that much these days 😅

[proven garnet]

Yeah I'm only using widgets in the UMG thingy and it was super easy to build and implement the HUD through that. Following this UE tutorial but wanted to try some stuff in my own project instead of just downloading their project and redoing everything they do.

https://dev.epicgames.com/community/learning/courses/l3p/unreal-engine-your-first-hour-in-umg/bLqe/updating-our-user-interface

[prisma cedar]

Like in Elden Ring for example

[trim matrix]

What the fuck?!

This does work

[lunar sleet]

That is what I said yeah

[trim matrix]

https://tenor.com/view/bubsy-explode-shatter-gif-24249692

[lunar sleet]

With what array size

[trim matrix]

The array size is determined by the actors array gathered by get all actors of class

It is 2/3, just tested it

Its unimportant

[lunar sleet]

Did you test with any other array size?

[trim matrix]

here's what i did

[trim matrix]

the last index changes when removing the elements (??)

isn't that set array suppoused to be cached?

It keeps returning the current last index instead of what it was at the time that node was executed

the first one is the index of for loop

the result is the same as if the last index was gotten like this

the same occurs for other var types:

arrays aren't cached

that makes sense actually

i think the person who made this had no idea that usually vars get cached besides arrays, or was trying their hardest to make this look unreadable

[lime basin]

I have made 3rd in c++ I have added new Enchanted input action here are a few questions and issues I am facing for the life of me I can't figure it out.

Why is the event graph in BP_ThirdPerson empty? I understand it's partly due to the code, but can you clarify?

I get that there are transition variables in AnimBP that control transition between animations but how does the Code know when these are activated? I don't see them in the code, or I don't see inputs in the Blueprint Evenet graph so how?

I added a custom action detected in CharacterBP Event Graph and set up a state machine and bool in AnimBP to control transitions. It should activate when I press RMB and return to idle. However, I'm unsure how to get it to work. In the Event Graph, I see no way to reference the bool that controls the transition in AnimBP. Can you provide guidance?

I am way to used to Unity animations so this is a little bit of challenge for me wrap my head around

[wary acorn]

Hi! I'm fairly new at this, I hope I'm in the right place.

I'm building a respawn system for a school project, where you destroy the actor to trigger the respawn. Theres a 2 second delay there, and during that period my camera view weirdly flips to the side. It goes back to normal once the new actor spawns.

Any advice or tips on how to fix this would be greatly appreciated.

(I've seen other similar posts suggest to use set target view with blend, but I didnt understand)

[fiery swallow]

Are you properly sending or setting that information to the animbp? Beginners usually do this by retrieving the variables from the character and then setting it in the animbp every frame. There's lots of tutorials on this

[dark drum]

Does anyone know if it's possible to make a component only visible in the editor when the actor is selected?

[fiery swallow]

Youre destroying the character you were using? If so then you could use a view target blend, or you could setup a spectator pawn

[fiery swallow]

https://youtu.be/uW86ZGxesmc?si=4XgsdpWgG9fU-LRp

[lime basin]

I am sure I do I just dont know how to use that bool that controls transition of animation in AnimBP for my RMB input action how do i link them together

[fiery swallow]

Oh you already have the variables setup properly in the animbp? If that's the case you just need to plug it into those little transition circles. You can open them by double clicking it lol

I forget what they're called... but you can see them in the picture you posted, it's the little circles next to the transition arrows

I'm on my phone so I can't really show it

[lime basin]

yes everything is set up and enchanted input action is set up, I have added animations just dont know how to link this bool to Input

[fiery swallow]

Not when it's selected. You'll need to use variables for this.. usually something called like "debug show components". And it's logic lives in the construction function

[fiery swallow]

You can probably have some logic for when it's selected through c++ but nothing like that is exposed to blueprints

[lime basin]

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, meta = (AllowPrivateAccess = "true")) UInputAction* AimAction;

[fiery swallow]

This should work, if it doesn't there is a logical error.

It's not being set right. You can use a print string to see if it's properly updating

[lime basin]

It does work but I dont know how to set up AnimBP to use this action

that isAminingBP to connect it to this Property in blueprint

[lime basin]

I will try this

[dark drum]

I thought that would be the case. I'll just have an editor function to set their visibility in the editor.

[lunar sleet]

If you’re destroying the actor when respawning it and the camera’s attached or it, it might be going to 0,0,0

[wary acorn]

Thank you! Ill check this out

[fiery swallow]

Yeah just to clarify, after watching the video. You want to change the camera just before the actor is destroyed

[proper wyvern]

does anyone know if there's a way to print the name and triangle count of all visible meshes?

[frosty heron]

In your anim graph, on event anim update. Set the isaimingbp of your animbp to isaimingbp of the owner of the anim instance

[ocean gate]

Any tips on how I should approach making a flexible toggle switch system in UE? I want to make it as flexible and modular as possible, so I'd rather not hard code in any specific actor classes it should work with. For instance, I imagine having two actors, a switch and an actor of some kind (a moving platform, a light, a door etc.) and I can assign the switch to the actor I want inside of the editor itself without having to enter the blueprint. Then when I toggle the switch it'll pass on to the target actor that it should be activated. Is this possible?

[elfin hazel]

The switch is an actor with an actor variable that is instance editable. You can now select any actor in the scene for that variable.
The switch has some method to be interacted with. When that happens, it calls an Enable or Disable interface message to the actor.
The platform actor implements the interface and responds accordingly. Something like that?

Or, the switch can be a component. It's location and rotation is set to world. When interacted with, it gets its owner and interface calls. Now that component can be attached to any actor in the scene, or in a blueprint.

[ocean gate]

Ah!! Interfaces seems to be the way I'm thinking of. Thanks so much for your help!

yep that did the trick perfectly, thanks again!!

[storm shale]

Does anyone knows how to create widget and add it to viewport without creating a hard reference to that widget?
I have a multiplayer project, where there is a login widget, and that will only be created when entering the lobby.

Once that's done, it won't be created again in the actual game, which is a different level alltogether

The issue is am creating the widget from Player Controller, so that causes it to always be loaded with Player Controller regardless.

[versed sun]

once you change the level, dosnt the ref reset ?

[storm shale]

I thought about creating the widget in the Level Blueprint, but since it's an online project, Begin Play and Event Tick only fire in the dedicated server

[lofty rapids]

what would be a soft reference ?

[storm shale]

yes but the reference to the blueprint still exists, like the Class and blueprint. The widget no longer exists but all their code or whatevs is still loaded, in case u were to create them etc.

[storm shale]

I tried that but they still are treated as hard references, so now idk what to do.

[lofty rapids]

i'm asking because i don't really know the difference

hard/soft idk

are you trying to not create at all ? or not even be able to create ?

[storm shale]

I saw this post about them https://medium.com/advanced-blueprint-scripting-in-unreal-engine/object-references-in-blueprints-4c0df7f4dc1d But it seems to be partially misinformation (or most likely outdated) cuz it doesn't work in practice

creating soft reference variables still loads them as if they were hard references

[storm shale]

You can test it in a new project. Create 2 objects, Only create a variable to the second object in one of them, as a soft reference.

Go to reference viewer

it's treated as a hard reference

[dawn gazelle]

It's all in how you are attempting to access the references. If you need a hard reference then there's no point in using a soft reference.
Creating a widget doesn't specifically require a hard reference to the widget class. You can have a soft class reference to User Widget. You can then set the value in that reference to the actual widget class you want to use when you go to load it, you'd async load it, but it would be a hard reference to the UserWidget class, but it wouldn't be a hard ref to the soft class of the actual widget class you want to use.

So then, this prevents this bluerpint from loading the actual widget class before it is actually required, but it still would require a hard ref to the User Widget class, which is more than likely going to be loaded anyway.

[lunar sleet]

Which part is not working? Also I said use branch not flip flop, it’s not reliable. Additionally, there’s an isValid node you can use, you don’t need branches for that part

[thin panther]

not in memory though

i mean you can look at that yourself

the implementation is not hidden

[lunar sleet]

If soft refs didn’t work it’d be a pretty big deal and we would know 😁

[thin panther]

a soft ref is basically an asset path

they're not going to add functions to asyncronously load them if they're just loaded anyway

sure, the path is loaded

but the asset isn't

[lofty rapids]

whats not working about it, is the sound playing ?

[storm shale]

When I open Size Map and set it to show memory it still shows that. I know that's how it's supposed to work in theory, but, imma share ss

[lunar sleet]

Ah what fun 😀

[storm shale]

I jsut created 2 objects, Atest and Btest, created a soft ref variable to B test, and it shows that.

[thin panther]

that's not in theory though.
that is how it works.
you can literally look how TSoftObjectPtr works in c++

the size map means nothing when thats how the pointer works

sure when the soft pointer is loaded it will take that

but not until

[storm shale]

then the size map is broken? I legit want to know, cuz ti's confusing when different sources say different stuff

[thin panther]

showing just the size of basically a string path wouldn't be much use in a size map

[storm shale]

perhaps it could be something that works in c++ but not in blueprints?

[thin panther]

no, they work in blueprints

[storm shale]

Is there any way that can be verified?, cuz ReferenceViewer and SizeMap both claim it's not working properly, as per the screenshots I shared.

[thin panther]

their long history of use and the fact that they exist because of the hard reference problem?

i mean i suppose if you really wanted to you could do some memory profiling with insights

but it's not worth it

[old orbit]

Hi! Im new to unreal engine, I need to make my cinematic camera into my players view when i start the game so i can have the animation of other things playing while the camera is doing its own animations. I assume this is a blueprint thing. Anyone know how something like this could be easily done? Thank in advanced. 🙂

[storm shale]

But both the tools provided by the engine to see references say they don't work. How come you be so confident and blindly believe they do XD. I just want to understand, if there's smth am missing... Like. I shared 2 screen shots one of sizemap and another one of reference viewer, They both show the soft reference as if it was a hard reference.

[thin panther]

How come you be so confident and blindly believe they do
Because there is literally 0 reason for them not to. From the source code. A soft pointer is not valid until loaded, thus it is not a valid pointer. The hard pointer gets made when you load it

it would defeat the whole purpose if it was an always loaded hard ref

the size map you are probably seeing is from the internal weak pointer it keeps

which is not valid

[lunar sleet]

It also helps having been around for longer than 2 weeks 😀

[dawn gazelle]

If you have a reference to an asset, it needs to know about that asset otherwise how would you be referencing it?
If you have a soft reference to an asset, it still needs to know about the asset BUT it doesn't need to load the actual asset. That includes the soft reference definition itself - if you're referencing it as the asset, then it must know about that asset, so of course it will be loaded.

[lunar sleet]

Telepathy 🙃

[thin panther]

thank you, for having the editor open to demonstrate it :P

[versed sun]

Here is what I came up with, but I'm not sure what you are doing with Volume Multiplier = 0
Also not sure what float AC Ambient Sound Vol A/B do
but , this plays 1 sound for 2 sec, then stops it
if you try to play a 2nd sound ,it waits untill first sound is finished before playing 2nd

[lunar sleet]

What’s the current behaviour?

[versed sun]

here ya go
bail on Flip Flops unless its quick and dirty testing

np, When there is a branch choosing between two similar paths, you can Usually find a better way
makes it easier to read imho

Okay so I am new, and I have this emissive material

And I want to infinitely shift the color of it all the time

The goal is: Switch the Material To the emissive material, then have it last 10 seconds then go back to the previous material

Its like an invincible state so is there any way I can infinitely shift the color over and over?

To replicate the code its just start a new 3rd person template, and put the code at the end of the third person blueprint event beginplay

[spark steppe]

you can do all of this within the material

I am trying to set up a blueprint for a UI Button where when you click it, you create a session

[carmine palm]

Are there built in things for interaction? or do I need to add blueprints to every object in world that is interactable and check closest actor and give them the ability to press E or whatever to use

[dawn gazelle]

Actor Components & Class Heirarchy

Biuld the logic once, reuse it 🙂

[oblique ibex]

Can you tell me how?

[rancid crag]

I am having an issue with my bitmask enumerator. Every time I close my project the enumerator I assigned to the bitmask gets reset to "None" even though I make sure to compile and save beforehand. Does anyone know how to solve this issue?

[carmine palm]

Yea I know about re-using. I was just curious if theres built in functions for doing it without me doing it the long way. or if I need to do from beginning: IE object>getClosestActor->send the E ui>highlight the object somehow>etc

[dawn gazelle]

Well, there's nothing built in to do that specifically. If you create it as an actor component then you'd only need to build that kind of logic once, and then just attach that component to whatever actors you want, preferably at the lowest level class that can support it so that any children of that class will also have that component implemented and you don't have to keep adding it to more and more actor classes.

Then if you ever need to make changes to the logic, you do it in the component and it'll update for all instance of it.

[carmine palm]

Yea thats what I did on an earlier projectfor a "pickup" function for attaining points from different objects

and just had it check object type that was stored on a struct on the objet

object

Okay I'll make a base class

[hexed wharf]

I've been racking my brain over this for past few hours I need some help

I have my BP_Player Blueprint, and I want to be able to make a reference to it so that I can access the variables inside of it, but I do not want to use a hard reference (so no cast to BP_Player).

I want to use a blueprint interface, but I don't know how to attach my BP_Player as an object reference and then use that Object reference in other blueprints to access the BP_Player reference itself (kind of like cast to BP_Player) and get variables stored inside BP_Player (kind of like as BP_Player).

I've tried adding the ouput of my interface to be the Object reference of BP_Player, but that does not seem to work, and I'm kind of confused.

A picture would be nice, or a video (I've already looked at many YouTube videos on blueprint interfaces, so please don't send me those).

[dawn gazelle]

If you want to access variables of a spawned actor, you need a hard reference to that spawned actor.
If you want to access the class defaults of an actor class, you need a class reference (which is still a hard reference technically) and you can get defaults from that.
Interfaces only allow you to feed in references and attempt to execute the interface on the object that implements that interface and how that object implements it. It doesn't allow you to just get something from no where.

The closest I can think of what you're trying to do is maybe make a Blueprint Function Library and create a pure function in it that:

1. Gets Player Character 0
2. Casts to Player Character 0
3. From the cast, reads some values that you want.
4. Returns the values.

This would then allow you to do something like...
GetPlayerHealth
and it'll give you a node that takes no inputs, and is pure, and only returns the player's health value.

[hexed wharf]

So a hard ref is inevitable

[dawn gazelle]

Example here I've done in a blueprint function library. When I call to GetPlayerHealth in another blueprint, there is no hard reference to Character or AbilitySystemComponent in the actor it's accessed in, however, there is a hard reference in the function library, so in the end, when it loads the library during game time, it will have to load these assets - luckily they're common ones anyway so they're most likely already loaded.

But otherwise, yes, if you want to access variables of something, that something has to exist in order for you to pull values from it.

And you need to somehow get a reference to that something.

[elder lodge]

any tips on getting a camera and the parent of the camera to counter-rotate so that the view doesn't change but the body does?

My camera LERPs from relative rotation to 0
But retrieving that in the world rotation for the parent to rotate works-ish but for a longer move squiggles a bit; I think it may be due to the variables updating as it goes

I could set it to snap and call it a day for now, but just throwing it out there...

[hexed wharf]

woah... looks complicated I think I'll just cast then

[jagged cipher]

Hey all, is there any way to set just few values of a structure without affecting the rest of it? I have a structure that can be later on expanded so just doing simple hooking up all the pins might cause issues later on if the struct will expand.

[dawn gazelle]

Set members, then you can pick and choose which to set.

[jagged cipher]

Thx

[dawn gazelle]

Has to be done by ref though, so if you're accessing it from a copy it won't work.

[oblique ibex]

Could someone help me with this? I'm new to UE5 and UE in general

The person who replied said it's all possible in materials but i don't know how?

[lunar sleet]

For that side of the engine you want to ask in #materials

[prisma cedar]

How do I make the player run in a circle when holding left/right?

Like in Elden Ring for example

[modest tinsel]

How can I limit the camera rotation speed so I cant just spin my camera a million miles an hour?

[charred berry]

@prisma cedar

ignore above not intended, need this https://forums.unrealengine.com/t/tutorial-blueprint-spline-locked-sidescroller-e-g-klonoa-pandemonium-style-game/8396

[prisma cedar]

This will help me with making the player run in a circle?

Why is a spline needed?

[charred berry]

yes, the ex isnt specific to that, but you can shape spline to be a circle

Its one way of doing it.

Look at the link, it shows the player following the spline. The shape isn't a circle, so move spline points.

afa the key issue, not sure, prob;. fairly easy in blueprint

if keypress is chosen move player along spline

[rancid crag]

I think Joe is wanting a 3D camera system like Super Mario 64 or Ocarina of Time where if you hold left or right it will slowly rotate the camera in the direction the player is moving and hence you will move in a circle due to the camera simply rotating. I could be wrong though

[prisma cedar]

Yep but the player actually runs in a circle.

[charred berry]

same thing essentially, key press, turn character around, for that If I recall, you load character blueprint and add rotation

then yes what I said above

[faint pasture]

without forward movement input? That's really hard to do

[prisma cedar]

I just want to add an arc to turning

Which would also result to running in a circle when only holding left/right

[bold plover]

do you wanna have the same kind of camera as elden ring/SM64? If you have that kind of camera set up, then your movement direction can be scaled relative to camera rotation instead of relative to character position and thatll do it I think

[hushed heath]

hello guys i have a quick question: I have mulitple pawns consisting of 2 BP's BP_Player and BP_Monster and they both have different HUDs. But if i play my game now and i run this in the BP_Player it also comes up on the BP_Monster wich i dont want

[bold plover]

if you're switching which pawn you're possessing, I think you need to remove from parent first. But either way, make sure the widget stuff only executes when you actually possess the pawn, not on begin play if they are both in the scene

[hushed heath]

worked thanks 😉

[prisma cedar]

You are right. Are there any tutorials on it?

[pine hatch]

Hi i wonder if anyone know why i am getting infinite loop error when i try to add local offset to a colliding component using a box colliders event s

ok i figured out i have to add tags to the component i want to add offset to .. and has to call a has tag to check if the component has that tag in that way it only try to add offset to those components..

[potent wedge]

How do i stop character movement if a box overlaps with me? I'm trying to make it so the character just stops moving entirely. This is the code i've done so far.

[edgy ingot]

Try movementcomp-> stop movement immideately

It will zero the velocity

[potent wedge]

wdym movementcomp?

sorry i'm a bit new so i'm still getting the jist of it

[edgy ingot]

The character movement component

It has a function called stop movement immidieatly

See how u run stop active movement?

Try run stop movement immideately after that node

[pulsar pulsar]

how would I rotate the player with the camera? Like in CS, Valorant or Cod etc

yea I have that but it does nothing but spin the camera lol. "Use Pawn Control Rotation" yea?

oh shit, yea found it now, cheers ^^

[potent wedge]

i tried but all it does is start moving the player instantly after

i tried adding a delay but it keeps running the code

i want the enemy to stop moving for 5 seconds then charge towards me

[edgy ingot]

You probably should use behavior tree to run A.I logic

If it doesnt stop when you call to stop movement, it could be that you are running A.I move to somewhere after the call to stop movement was made

Use print string to debug

[potent wedge]

cheers

so it SHOULD have the range to be visible

Any help would be greatly appreciated

[versed sun]

I would do this then
The first time you play a sound , the AC Ambient will be empty, so it sets the Timelines position and plays from that point (Turning up the volume)
After that , it will play from start (Lower the volume, change the sound, raise the volume)

oh, add a anti-spam check in beginning

[fallow needle]

The reason why I had a flipflop and 2 variables for everything because i need 2 sounds at once during the crossfade so the transition between ambient sounds is seamless

[versed sun]

haha , i knew crossfade was next 🙂

[remote meteor]

dont really need a timeline

you can use FadeOut() and FadeIn from the UAudioComponent

if you want the audio to keep playing in the background, in the sound asset, set the Virtualization Mode to Play when Silent

[fallow needle]

how would we go about that?

[fallow needle]

ur putting in tremendous effort btw by creating the blueprint graphs for me i am greatly appreicative of that by the way

[versed sun]

make sure Volume Multi is 1 on the Spawn Sound

as long as you understand it

the sidetrack thinking of code resets my brain for what im doing (Sometimes)

[fallow needle]

no sound at all with this method, and vol multi is at 1

[versed sun]

hmm, now im not getting sound either after reloading...

NM, mine works
Did you set the Fade In/Out duration to 1 ?

or however long you want the crossfade

[fallow needle]

Yeah i set both to 3 duration

[versed sun]

whats your code look like ?

try Linear on the Fade Curves

[fallow needle]

ok so it plays the new sound, it fades in, but then it fades out instantly and then nothing

[versed sun]

mine works smooth, hmmm

[fallow needle]

it seems to be playing both the fade in and fade out at the same time on the same sound

[versed sun]

what UE version are you ?

im 5.2, doubt that they changed it...

maybe add a little delay in the middle ? ?

[polar wing]

In Lyra B_WeaponSpawner. Is there a way to specify in the blueprint which weapon to define instead of the details window? Right now the current spawner does not work when rewarding things through opening a chest by spawning the weapon spawner actor into the level since I can't predefine the weapon definition beforehand.

My workaround is just placing them outside the level and teleporting them with predefined definitions when the chest is opened.

[thin cradle]

is there an equivalent of onbegin/endoverlap for actual collisions? ie events for when something starts and stops touching something else

OnHit seems to only cover initial hit, not things no longer touching

[versed sun]

?

this way wont set the AC Amb until after the fade out

eww, spamming it keeps making more sounds...

[lunar sleet]

Good😈

[versed sun]

are you cycling thru songs or something ?

[frosty heron]

Seems like you are creating new ref everytime you call the function.

[versed sun]

odd, this way for me seems to work perfect

[polar wing]

nvm figured it out. In c++ changing BlueprintReadOnly to BlueprintReadWrite.

[versed sun]

np, glad you got it

[turbid ether]

Apparently, combo boxes changed during run-time are not easily localizable by default as they use strings for options rather than text. The solution I found was to just have a function to refresh them. But my Question is: Is there an event that fires in the blueprint when the language gets changed? I couldn't find any.

[carmine palm]

Quick question

How can you outline an object via bp

For doing interaction

Want looked at item to basically do wireframe around outside of mesh to show its object about to be interacted with

[turbid ether]

Set up your material as a Dynamic material instance, you will get a reference to it where you can set your Scalar Parameters, the rest is done in the material it self. I think #materials might be a better place for information on how you create a material with an outline.

[carmine palm]

Ty

[frosty heron]

Outline isn't equivalent to wireframe tho

And I think normally outline is done with post process volume with custom stencil buffer

Covered by tutorials widely

[trim matrix]

Hey all, I have a graph that is supposed to iterate over an array of MaterialParameterCollection's, and I basically want to iterate over each index and start a unique loop at a different speed, according to the Speed param. This doesn't work, and neither does a Set Timer By Event. The Issue with Set Timer by Event is I need to run that loop once, and start a unique loop for each, once.
Thanks!

[zealous moth]

1. do not ever delay inside a loop, it does not do what you think it does
2. You should pass the math from your macro inside of your material and just have an alpha value change instead. That would throw it onto the GPU and be more efficient.
3. Why not use a timeline? Is this supposed to be on tick?

[zealous moth]

they updated this a while back to avoid stencils altogether, i forget what it is called

@carmine palm ^

[trim matrix]

1. Gotcha, noted
2. This is a collapsed graph, so I could do that, but would it do anything?
3. Never seen a timeline, I just want to execute the same code (get scalar speed, multiply by other scalar and return) for each array element. I have a new revision here that works a little better, I can see it executing in debug, but it crashes, and won't work on anything but the first array element

[earnest swan]

Oh it could be that the loop is creating a bunch of timers, but the event you're firing wont use the objects at different indexes, since that isn't part of the loop

[trim matrix]

The part that makes this hard is that these scalars need to be added to slowly, it controls the opacity of the object. If it didn't matter, I could just keep the old one most likely, it needs to wait a half second after its called though, and continue at the same time. Get array element 1, branch off and start a wait, and while waiting move to the next array elem and do the same. The problem is moving to the next element while waiting

[trim matrix]

Yeah thats what I said in the message to lol, it only runs on the first array elem.

[zealous moth]

use a timeline

[elfin hazel]

It kind of looks like you don't want the loop before the "set timer by event", but have the loop after the event is called.

[trim matrix]

I'll look it up

[trim matrix]

It's a weird issue, the problem im trying to solve is starting N amount of loops at X speed based on N amount of MaterialParameterCollection and X from each MPC.

So I want to make all N loops at begin play and keep looping forever

and update X when it changes

[earnest swan]

It may be very very cursed but could you have flow pins loop back around and have a delay at the end? Essentially making your own while loop 😅. Remove the for loop node

[versed sun]

Here is a nice one i used a while back

[zealous moth]

@versed sun you can use blueprint ue share 😛 >>https://blueprintue.com/

[versed sun]

thx , always forget that site

[marble tusk]

There's also the snippets page on the dev site which is powered by blueprint ue https://dev.epicgames.com/community/unreal-engine/snippets

[earnest swan]

Oh damn, that's cool

[versed sun]

https://blueprintue.com/blueprint/3_gepyx7/

[zealous moth]

wow that is so restrictive

[trim matrix]

Infinite loop no? I would need a branch, that might work though lol, ill try it later

[graceful trench]

Logic Flow Question - I have a widget that is created when a level is loading and will disappear when "Is Loaded" becomes true. Right now it's on a tick. How can I use an "Is Loaded" that's not on a tick and will return true or false when the level is loaded?

[earnest swan]

yeah you'd need a branch

[elder lodge]

Is this right? It works 99% of the time but occasionally wigs out, often when I'm upside down

[versed sun]

check that Shortest Path

that stops 99% of my wigouts

then you're 99.99% good

[wind spire]

do i need to run load settings every startup(in menu level or game instance) or it runs automaticly?

[elder lodge]

This? Output?

[elder lodge]

Or is it like a gate?

ooooooo

Seems gucci t hanks

[lunar sleet]

That resolution tho 😀

#cpp still, you may have some missing flags or something

[civic shadow]

oops, my bad. I will ask there

[zealous moth]

anyone got a good runtime blueprint plugin or something to make BP nodes at runtime? I can make my own nodes but at least the base

[lunar sleet]

What’s the use case, jw

[zealous moth]

an point and click/drag drop to solve puzzles using nodes

[thin panther]

if there was, it wouldn't be shippable

per the eula you can't ship editor code

you'll have to come up with your own node graph

[feral ice]

there has to be a better way of doing this right? I am checking if the rotation is between two values and if its 87 degrees it rounds it to the closest out of [0,45,90,135,180,225,270,315,360] and that should be 90. There has to be a better way of doing this. Can i put [0,45,90,135,180,225,270,315,360] in a list and then use a funciton that checks what value that its closest to?

this is the way im doing it now

[fallow needle]

yeah just get value / 45 and truncate

then * 45

[feral ice]

ok

yeah thats true jesus thankjs

hahah

[thin panther]

you want to round not trunc tho

[feral ice]

its not a memory i want to keep

[thin panther]

no

trunc means sever the decimal place

aka it's always a floor iirc

[mental trellis]

It's right there in the name.

Truncate: (of a leaf, feather, or other part) ending abruptly as if cut off across the base or tip.

In the function too.

[mental trellis]

Depends what floor does with negative numbers. Floor(-1.5) might be -2.

[lunar sleet]

Sounds more like pruning but I guess that was already in use 😅

[zealous moth]

no no, not editor code, I don't want to reproduce UE5 BP at runtime, just the interface where I can link nodes that do stuff

[thin panther]

that's a very fair point

[zealous moth]

for instance, Input color -> add red

[thin panther]

thats editor code

[zealous moth]

?

[thin panther]

you will need to make your own

[zealous moth]

yeah I get that

[lunar sleet]

There’s blutility stuff too

[thin panther]

even just the graph that you can add bp nodes into is editor code

[zealous moth]

blutility?

[mental trellis]

If it's in an editor or developer folder, it's offlimits.

[zealous moth]

i would use widgets

[thin panther]

you can absolutely make your own visual graph based language, like blender nodes or whatever.
but this is not bp. you are not making bp nodes

[zealous moth]

I meant, is there a solution out there already made that mimics BP logic with meatballs and spagghetti

[thin panther]

https://www.unrealengine.com/marketplace/en-US/product/open-logic-editor

it says you can use this in game, but by the same token it looks to be using editor slate code in some of it's examples

if that is stripped then it's all good

[unkempt fjord]

I have a collision box that I to trigger spawning a piece of geometry. I want only the AI to trigger the collision box and not the player. My AI is BP_AI_Npc, how do I set this up for the input object in the is valid node?

Another version I have is for only the player and not the npc and it works when i connect 'get player character' into the 'is valid' input object. Just not sure how to get the BP_AI_NPC in there. Any idea?

[lofty rapids]

usually you can get other actor and cast it

[unkempt fjord]

what do i put into object for the cast to node? I'm expecting I want something like capsule component or mesh from the bp_ai_npc but its not coming up as an option that i can find

[lofty rapids]

other actor most likely

are you trying to see if that thing overlaps ?

i also don't think you need is valid

just if the cast succeeded or failed

[unkempt fjord]

Other actor worked! thanks a lot engage

[thin panther]

you should watch the blueprint communication video in the pins on what a cast is

its a type check. "is this actor of this more specific type"

i.e. "is this animal a bunny, if so let it do cute bunny things"

[wicked cairn]

Anyone know a good article or tutorial on how to keep track of where the player is during their progression through a story/rpg (text dialogue and completion of a quest with the quest's id)?
I was thinking of using a bunch of booleans with data assets, but unsure if this effective or if theres a better way to put the system together

[molten tinsel]

can someone explain me why this simple line trace doesn't work? Is it because the cube is inside the same blueprint as linetrace? But it doesn't make sense

[lunar sleet]

It works fine, you just don’t have collision set properly on that wall

[dawn gazelle]

You could technically store just reference to the data assets themselves in an array indicating their completion.

[molten tinsel]

Isin't block all supposed to block linetrace?

[lunar sleet]

It is

But upon reviewing your question and video you might have had it right the first time

Why are you tracing from a wall instead of from the char?

Is the light your “ai” ?

[molten tinsel]

Well I want to trace from the center of this sphere to the player. But it ignores everything inside the blueprint what is in front of it.

[lunar sleet]

Well yeah if that wall is in the same bp, you’d need to turn off ignore self for it to pass through it

[wicked cairn]

Oooohh wait you're right thank you

[molten tinsel]

oh ur right, I didin't know it's global across entire BP

I thought it ignores start/end point only

[lunar sleet]

Nah, self means the whole actor

[molten tinsel]

it still refuses to work with or without for some reason

[lunar sleet]

Are all those lights instances of the same bp?

[molten tinsel]

yep

[lunar sleet]

Take me through your line trace code. You have this in the light bp but it’s set to start from the char’s root component and end at the cube (idk what that is on your map)

[molten tinsel]

There is really no code. The blueprint is just no collision cube which represent crystal, a test wall to test line trace and collision to start the line trace when entering

[lunar sleet]

What I’m asking is, why are you starting a trace that’s meant to start from the character from inside the crystal bp

You should ideally be tracing from actor to actor (not component to component)and not have the wall be part of the same bp as that crystal thing, and your trace code (nodes are also code) should be on the character itself.

[molten tinsel]

So, my goal is when player enters the blue zone, we make line from crystal to player and there is smaller collision sphere which represent the radius (red one). I need the hit location so I can pull the crystal into this location and I wanted to try doing this with raycast, no vector lengths, math etc.

[lunar sleet]

Ah I think we had that discussion yesterday in this channel with another user. You prly want your trace to overlap the box on its way to the crystal

[lunar sleet]

A multi-line trace to be precise #blueprint message

[molten tinsel]

ill try checking it

[harsh tiger]

Hey, is it possible to have a DetailView widget in a EditorUtilityWidget display multiple assets details at once and edit them?

[faint pasture]

You need to trace the other direction to get that hit

[random pulsar]

hi guys,i just made a child of my character ,that will be the rabbit ai and the problem is in flipbooks,how can i access them and change in the child

this are things i want to change in the child

and this is the child

[modest tinsel]

Is there a way a can cap the max camera movement speed kinda like how you can adjust the mouse speed?

[dawn gazelle]

If the logic is needed to mostly stay the same, but some values need to change in the child, promote the values you want to change to variables.
If you want the logic to be different, override UpdateAnimation.

[trim matrix]

Finally back home, and it doesn't seem like this would help, could you explain why you think I should use one? I want to get from 0 to 1 over time, and then go to 0, and back to 1. Which is what my previous code worked, does a timeline just replace that?

[dawn gazelle]

You can define a curve on a timeline and have it output values as you need them over the course of the duration of the timeline.
They're easy to start and stop when you need, and can even loop if desired.

[trim matrix]

guys i created a simple grenade but it doesnt seem to do any damage

I am a newbie to blueprint programming in UE5

I am trying to test something extremely simple so I can implement this in my game:

I tried to follow this video tutorial:

https://www.youtube.com/watch?v=jvte8lNyNJ0&ab_channel=MBC

I ve an event writebob inside Bob BP.
As I understood the video you have 1 blueprint in which you have an event, and 1 reference to it
In my case Bob is the blueprint the custom event is writebob
So in the 3rd person character bp I ve a variable wherebob which is set as type
Bob.
So In my third person character bp. I access the wherebob and call on the function writebob that should write bob.

I thought I was calling writebob in this process but I must be missing something
blueprint runtime error: accessed none trying to read property where bob, node: write bob: graph, function execute ubergraph bp third person character blueprint: BP_thirdpersoncharacter

Any and all help, tips, guidances, suggestions would be greatly appreciated! thank you!

[dawn gazelle]

Single player game?

[dawn gazelle]

Accessed None errors indicate you have a variable that doesn't have a reference set in it. While you may have created a variable of the type "Bob" you haven't populated it with the reference to the specific instance of "Bob" you want to communicate with.

[trim matrix]

Hi all, im currently trying to setup a respawn system, so when a player hits a specific checkpoint, if it hits a collision box it will be respawned back at its current checkpoint that it last hit, but its not working for me.. im really unsure on how to fix this as i had just previously watched a tutorial but had to make changes as my game has different functionality 🙂

the respawning system does work, it just doesnt respawn at the checkpoint it last previously hit

[frozen spruce]

Hey guys, is it possible to detecte a front raise /
rising edge ? because when my condition is true, "Etapes" is incrementing by 3... I don't know if im clear enough (im french lol)

[carmine palm]

Does it just respawn at 0, 0, 0?

0 0 10

i mean

You're not setting the checkpoint_location as far as I can see

So its always 0,0,10

you'd need to set it in the trigger

[trim matrix]

Okay yeah! I figured it out, but I want it to reverse once it reaches the end. I could do 2 things here, just copy and paste my curve and make it fade out at the end so it appears to reverse when it loops, or I could try to fuck with the reverse input, what do you think?

[carmine palm]

the new checkpoint location*

so your object world location

[trim matrix]

Like so, or I could do it the BP way, this feels a bit hacky, but if it works it works i guess

[trim matrix]

do you have an example you could show me?

by any chance

im a visual learner lol

[trim matrix]

let me look too

[trim matrix]

so would i just "get" trigger

or something

[carmine palm]

no

uh

lastCheckpoint is the object ref right?

[trim matrix]

https://www.youtube.com/watch?v=2X0nYIV9L70&t=267s its from this

but i believe its just a variable

[carmine palm]

See if you can do

in the bp third person

[trim matrix]

do what

[carmine palm]

oh wait

you dont even have your checkpoint in there

[trim matrix]

what do you mean

[trim matrix]

yes

[lunar sleet]

Does the overlap fire? Do you know how to use breakpoints, I can’t rmbr if we talked about that

[carmine palm]

Does last_checkpoint return anything

like does it return the object

in your 3rd person blueprint

[trim matrix]

like the if collided?

[trim matrix]

uhh

lemme see

[lunar sleet]

Yeah the red event

[carmine palm]

need to do last_checkpoint->getWorldPosition or whatever.

and set player location to that

[trim matrix]

it gives a print string (Working) when i hit the checkpoint

[carmine palm]

well yea thats just end of overla

overlap*

[trim matrix]

is this correct @lunar sleet ?

[carmine palm]

Right now you aren't feeding it a position from last checkpoint

so its always 0,0,10

[lunar sleet]

Work calls brb

[trim matrix]

ohh so where do i put this?

[carmine palm]

in ur 3rd person try doing last_checkpoint->getWorldPosition or whatever

not sure if last_checkpoint is a valid ref tho

and then set position to that

[trim matrix]

oh in the bpthirdperson game mode one?

[frozen spruce]

can someone help me ^^

[trim matrix]

like this?

[carmine palm]

yea in the game mode one

yea

[trim matrix]

and then do i connect it to thisd one or this one? or both?

Is there a way a can cap the max camera movement speed kinda like how you can adjust the mouse speed?

[lunar sleet]

A clamp prly

[trim matrix]

[carmine palm]

Nice. I just started college for dual major in comp science with focus in game development and also major in game design with focus in programming aspect

oh wow!! impressive, hope it goes well for you, im going into a graduate position in sales enablement in the cloud sector of the company im with, and it has absolutely nothing to do with game development lol

[lunar sleet]

Place your key frames further or closer along the time axis

[carmine palm]

[trim matrix]

anyone got tips on a good save system?

[trim matrix]

Yeah, but I want to make it dynamic, I would have to edit it at runtime, seems needlessly complicated

[lunar sleet]

What is your actual goal with this?

[lunar sleet]

This might help https://youtu.be/_4usRrTiqak?si=l7XauZiTUryn10qL

[trim matrix]

thanks neo i will give this a look!

[trim matrix]

This curve will control the opacity of VDB clouds, using a MaterialParameterCollection. I want to be able to make them fade in and out at different rates to simulate clouds forming. So, I want to control the speed using a variable in BP

[dawn gazelle]

Ok, only one other thing I can think of is that your actor that's supposed to be hit by the grenade doesn't respond to the visibility trace channel or something is blocking the trace before reaching the actor.

Otherwise what you have there should be functional.

[lunar sleet]

🤔 this might be done better directly in the material

Maybe apply the randomness by changing params on the mat instance

[trim matrix]

Yeah I used to use this, I just thought that it would be better to use the BP to control it

[carmine palm]

Watched video on how to apply a glowing outline on objects lol

just need to figure out adding post process effect via bp on approach

[lunar sleet]

I doubt it. Like I said, you can use bp to change a mat param tho, so you can achieve that randomness with each cloud

[trim matrix]

It would apply to every cloud though no? I can't say to apply to one or the other cloud, cause its all under the same material

[lunar sleet]

Every instance

[trim matrix]

Yeah so that wouldn't work

[lunar sleet]

Do you only have 1 cloud instance ?

[dawn gazelle]

You can set the playback rate of the timeline. So if you have your timeline as a 1 second timeline, all you have to do is divide 1 by the actual duration you want to get your timeline to play for the correct amount of time.

[trim matrix]

Dynamic Material Instances don't work on Heterogenous Volumes, so I would need to make like 10 materials, with 10 Material Parameter Collections, and make an array of them.... exactly what I was doing before with my for each loop 😂

[lunar sleet]

Ah damn I didn’t realize

[trim matrix]

Yeah it pisses me off that they don't work, but you can use MPC's for some reason, Heterogenous Volumes and SVT's are brand new though, might change in the future

[lunar sleet]

I guess Datura’s solution is the best one then, once again 😁

[trim matrix]

What would be great is if I could do it in the material, but idk how to make it random enough on a large timeframe, so im using the bp

[lunar sleet]

Speaking of, how would I make the timeline be frame independent, can I use this set playback rate you mentioned with like * world delta ? @dawn gazelle

[dawn gazelle]

I don't think so. Timelines update exec fires with the frame rate, so their position in the timeline when its called should be based on the current position + delta which is then set as the new current position.

[lunar sleet]

So you’re saying they should be frame independent to begin with?

[dawn gazelle]

I'd think so.

[lunar sleet]

It doesn’t seem like it, I am using a timeline to make some lasers move on a wall. And if the frame rate is lower, it seems to affect the end result

[dawn gazelle]

o_o

[lunar sleet]

Yeah, I’ve noticed this issue before with timelines, and I saw someone saying they’re frame independent before too but I seem to be getting the opposite result 🥲

[dawn gazelle]

Maybe it's because of the tick group?

[lunar sleet]

Oh

[carmine palm]

Neo any idea on this:

[lunar sleet]

That’s in the timeline settings? I can test

[dawn gazelle]

Yea it's at the top above the curves

[carmine palm]

so I have my post-process effect that I can set on object. and now I can set custom render depth to true once player is looking at it, which would make it use the post process effect. I'm trying to figure out how to add the effect to the object via BP

actually I might have found it just now

[lunar sleet]

Neither option nor the ignore time dilation worked sadly

[trim matrix]

Wait, how?
basically, 1/10 would be 10 seconds on a 1 second graph, but what do you divide by?

[dawn gazelle]

by the number of seconds you want it to be.

[trim matrix]

Yeah I get that, I worded that badly, I just mean like, what do I hook that up to in the timeline node?

[trim matrix]

OHHHHHH

I see

I didn't know about the Set Play Rate node

[dawn gazelle]

Oops, have 10 in the divisor but comment says 3 seconds...

lol

[trim matrix]

haha

[dawn gazelle]

Is there something you're doing to change the frame rate itself?

Like some console thing for testing?

[lunar sleet]

I tried both capping it with t_maxFPS and just having it happen naturally due to a very expensive, yet to be optimized 😅 Niagara system

Same end result

I’m using it to add x and y values over certain time intervals to the end of 2 line traces, essentially making it trace a square on the wall. But the more the fps drops, the more inaccurate the result is.

Like if my editor goes out of focus and it drops to 5fps because, idk windows optimizations, the traces don’t even end up moving much

[dawn gazelle]

That's probably why... If you're adding a value from the timeline, then the timeline won't always have the same amount added up.

[lunar sleet]

It won’t ?

I thought adding fixed values over a fixed time interval, that’s supposedly frame independent would mean I’d always get the same result. I guess I’m thinking of this wrong then?

[trim matrix]

Yo the only Set Play Rate node I have takes in a sequence as an input, what're you using?

[dawn gazelle]

Timeline works based on a input time interval and it outputs a value.
At 30 FPS, it'll try to read the next value stored at 0.032 seconds and output that.
At 60FPS, it'll try to read the next value stored at 0.016 seconds and output that.
At 120FPS it'll try to read the next value stored at 0.008 seconds and output that.

So if you have varying frame rates, it can't output consistent times from it, and if you're adding up those values to come to a summed value, it can't add up as it doesn't have all the same values.

Maybe a better way of looking at it:
At 120 FPS, you'll get double the amount of values output from the timeline that you would from 60FPS.
At 30 FPS, you'll get half the amount of values output from the timeline that you would from 60 FPS.

[trim matrix]

Blend space, or sequence

[dawn gazelle]

Grab the reference to the timeline component from the left hand side and drag it on to the graph, and from that do "Set Play Rate"

[trim matrix]

Gotcha that makes sense

[lusty hedge]

but i cant find a way around that

theres so many annoying features in my way i just want to code some objects

Ok, so it’s 1/FPS… which makes perfect sense now given the name 🤦‍♂️ . But based on that, could I not just adjust the play rate based on world delta to get consistent output values? 😅

you're using an engine purpose-built for 3d games with lighting, there's going to be some annoying stuff in your way if you aren't using it for that purpose

Maybe? That seems like not a great way of using a timeline. A better way would be to just have it output a value from 0 to 1 and use that to lerp between the starting value and the ending value.

damn.

Right, but the problem is I’m drawing a square using 2 line traces so I have x moving over the first interval and then y over second interval and then back to x. You thinking I should be using 3 timelines back to back instead ?

unreal is the only thing i kind of understand and im having trouble making a simulation

im trying to make a clean 2d workspace

[hollow pond]

you can use a postprocess volume to display the scene as Unlit if you're still working in 3D

[lusty hedge]

that helps thanks!

i can just use an orthographic camera too right

[hollow pond]

that won't change lighting

[lusty hedge]

but then its still making geometry for spheres

[hollow pond]

well... it might break the lighting lmao

[lusty hedge]

if its unlit how would it break
