blueprint

[soft peak]

in animBP there you can debug directly in "Anim Preview Editor"-Tab
but is there a way to see this changes while playing too?
https://i.gyazo.com/d474fabdaf48b320bd02683ebc582b15.gif

[spark steppe]

yea play, open the blueprint and on top theres a drop down to select a debug object

if you select the active instance it should show what's happening

[soft peak]

i did, it opens up a new window, but it did not show what i was looking for, did i choose something different?
https://i.gyazo.com/05134e742e9e8825976a7599b5f58f94.gif

[spark steppe]

yea you did

might be hidden there

[soft peak]

😄
so i chose Debug->Blueprint debuger

ahaa

[modest monolith]

is that how you send big videos ? trasforming them into gif ? genius lol

[soft peak]

-.- really....

there we go:
https://i.gyazo.com/05134e742e9e8825976a7599b5f58f94.mp4

[spark steppe]

but that's what you've been looking for?!

[soft peak]

actually there was no debug in that arrow thing

[spark steppe]

huh

[spark steppe]

yea the dropdown

there you can select objects from the PIE when it's running

[soft peak]

oohhh...now i get it 😄
thanks ben

never had guessed that

[spark steppe]

the same thing also exists in normal blueprints btw

if you ever need it, now you know

[soft peak]

from ben to ben, thanks 😄

when working with animation states and transitions rules based on booleans
is it possible that it can stuck in a state?
(when i hitting multiple times the key it got stuck)

https://i.gyazo.com/d426f6a7a038ff94caf6a40cd27e3ab9.mp4

hitting the key, is setting the canEnterBoolean to true

which could solve that problem is, if we would have anode in the state where i can ask "is animation done playing", is that even available?

found it finaly: get relevant anim. time left

[icy dragon]

Why not use montages?

I mean, it's up to you if you really want to use state machine for one off anims, but montages would be infinitely better for such thing.

I can imagine how horrible that SM setup would scale as you add characters and whatnot

[cyan bone]

I have a bunch of stuff they need to happen when my character is moving. Things like some smoke effects and animations.
But i need them to stop once the character stops moving, so this is what im doing. I check constantly if the has velocity. Is this the right way to do this?

Something feels like this is not the right practice. Is there something like Event on Stop Moving ? Or Event on Start Moving?

[earnest tangle]

This is an entirely acceptable way of doing it. There is no builtin "started moving" thing

Depending on how you want it to work, you could use anim notifies as well to trigger based on animations

[cyan bone]

thank you. im so bad yet at character anim, you mean the one in skeletal mesh? so i guess i will just go with set timer event and a checker of velocity

this will also work in multiplayer right?

[earnest tangle]

Yeah if you don't need for it to instantly react then checking it on timer probably works well for it

Not really an expert on mp, but as long as you replicate things correctly it oughta work

[cyan bone]

yup the only thing annoying is that i cant use delay

[brazen leaf]

Im having trouble conceptualizing a solution for this, maybe one of you has an idea.
To let the player start a game action, I want to compare a list of required actors to a list of 'inventory' actors. Like if the player tries to begin baking a pie I want to be able to require they've put 2 Apples and 1 Flour in the oven first.
I get a broken brain halfway through implementing anything I've thought of.

I last tried setting up the requirements as an array of actor class references, like [apple,apple,flour] but couldnt find a way to get the class of the items in the inventory. Get Class gave me Actor, not Fruit_Apple (im not making a baking game, just examples 🙂

[desert juniper]

iterate through a list of required items and their quantities (Create a struct that holds an item class, and an integer for quantity)

then check to see if the player's inventory (or who ever's inventory) contains those items, and enough of them

[solid zenith]

I want to render sphere ahead of camera while button is held down ive got everything except moving sphere, tried several nodes couldnt get it to work, how do I connect these so it would run repeatedly?

[brazen leaf]

any idea why an actor wouldnt be getting Event Tick? Im watching one BP during play and the red line coming off it is constant and on the other its never firing. ('start with tick enabled' is active on both)

[scenic magnet]

Is there a shortcut in blueprints for making a value that follows a sequence through time. For example having an object scale up and down using a sine wave.
I would normally just keep a float var and add deltatime to it each tick, wrap back to zero once it's greater than 2pi, take the sin of that float each time around for the scale. I know how to do that but thought there might be an alternate way to do it with BPs.

[mystic bough]

timeline

[dawn gazelle]

You may need to select the instance to see it firing. While the game is running you can select the instance to monitor from the drop down beside where the play button is.

[brazen leaf]

That's a helpful feature I just figured out today but that's not it. I can see On clicked fire and when I just try printing on tick nothing happens either. I did paste it from another blueprint. Maybe it has some weird baggage. I'll try re-adding it tomorrow

[dusk cave]

I'm trying to spawn my pawn at my players location but it doesn't work. What am I missing?

[hardy merlin]

Not sure if this is the right channel, but is there a way to create a blank animation?

[brazen pike]

Where are they being spawned instead?

[dusk cave]

at 0, 0, 0

well actually

when I try to print the location, nothing shows

and the pawn is not shown in the outliner

but the game does switch to the camera that I'm using on the pawn

[brazen pike]

Well, first of all I can't see a reason why you'd need to set it on tick since it doesn't need to be updated every frame. You can just get rid of the variable and connect "get actor location" to it directly. Also I'm unsure what it is gonna do when you convert vector to transform, you could just split the transform pin and connect "get actor location" directly into the location pin.

[dusk cave]

i tried plugging it in but got the same result

[brazen pike]

Even when you split the pin?

[dusk cave]

let me try that

nope still didnt work

[brazen pike]

Can you send a screenshot of what you tried?

[brazen pike]

Hmmm, you're saying its always spawning it at 0,0,0?

[dusk cave]

when i try to print the location, after i spawn the pawn, nothing shows up

and the pawn is not listed in the outliner

so im assuming something's wrong with my spawn code?

[brazen pike]

Okay, I'd have thought this would work so my next suggestion is just a guess, but maybe try using get world location rather than actor location

[dusk cave]

nope

getactorlocation should've been at least one of the nodes I need not sure why its not working

[brazen pike]

Breakpointing possess and checking the value of the location gives you 0,0,0? just to be absolutely sure

[elfin wolf]

the problem is the spawnactor node or the drone BP itself

[dusk cave]

I don't have anything inside the drone BP besides the code to pick it up

[elfin wolf]

if you spawn it without possessing it what happens

[dusk cave]

hmmm i dont see it i think

yea its not there but I have a cube mesh on it

I can see the cube when I possess it

[brazen pike]

The drone hasn't been set to be only visible to its possessor right? (I forget the terminology)

[dusk cave]

it is still visible

i fixed that checkmark

[brazen pike]

okay can you try to print the location again? And show the code you use to print because nothing showing up means something is probably wrong with the print

[dusk cave]

i got it to print the location and it says 0, 0, 0

even tho i dont see it

[elfin wolf]

even if the location was 0 it would still spawn in the outliner

[dusk cave]

its not there

[brazen pike]

do you have to be exact with search? since the name is BP_drone

[dusk cave]

no

bruh i got it

If I change the collision to always spawn, ignore collision it works

i dont get that

[brazen pike]

Oh of course, damn I thought collision be it but wasn't sure. yeah its because its seeing the spawn location is inside the capsule component of the player and deciding it shouldn't spawn if its going to be blocked

you just have to tell it to spawn anyway

[dusk cave]

ugh that makes sense

thanks for helping me out yall

[elfin wolf]

lol it's always the simplest stuff you don't think about

[dusk cave]

exactly

[uncut salmon]

I have a custom channel which i use to track certain objects to break with 'destructible' which I have set to block. However, this doesn't take effect unless I put in this blueprint. Am I missing something to set this up in the sidebar without putting it into blueprints?

Hi all, I have a function with a return variable that might be none, which is ok because i handle that outside of the function. However, i receive an error about it in the message log. is there a proper way to handle that?

Btw is there any limitations on how many instance static mesh actors are possible ??

[dusk dust]

Hello. I am trying to get my quadtree to update based on player location. Currently it runs on construction script and updates when I move a point, represented with a vector variable. Adjusting this point updates the quadtree immediately

Now I am trying to update it based the cameras location rather than a point I manually move around

I can't access cam location in construction script so I need to do everything in the event graph

But there is a problem

The way my quadtree works is by creating a new master square, and then subdividing it by deleting the original square and creating 4 new squares

You know what

Nevermind

[opaque acorn]

?

[undone surge]

what is the best way to do an area of effect explosion damage? do i create a collision sphere after explosion ?

[opaque acorn]

Use overlapping event

Spwn a/ make a boolean like if x was done then sphere on begin overlap get actors

Then you can spwn impact effect/ damage/ impulse force etc

If you use tags or gameplay tag then you can specify whom to affect

[serene bramble]

I have a bunch of strings I want to access in the blueprints (story lines/their subtitles) but not sure how. I tried an Enum but it doesn't have a key->value type mapping. Any suggestions?

(Idea is to set the string in my code to "Storyline1" or something then the storyline is stored in another file (json maybe? {"storyline1": "This is the storyline"}))

do we have anything similar for Decal component?

[digital needle]

guys can anyone reference me some sort of tutorial or provide guidance on how can i replace the default maniquinn character to a custom character and use that character at runtime

[earnest tangle]

google for something like ue4 custom character model, ue4 mixamo character, or something like that

mixamo has a bunch of stuff you can easily import into ue4 so that query would probably get you a bunch of examples on how you can do custom characters

[signal hornet]

Hey guys, I'm currently trying to get player overhead name tags working. I'm trying to do it so that the player can set it from the main menu before joining the lobby, so I'm wondering what the best way to set the 'input text' to a 'user data storage' so it can be re-accessed and RepNotified upon joining the server? Thanks

[earnest tangle]

stick it in your game instance, that persists through level loads

[signal hornet]

Thanks!

[undone surge]

i have a projectile that is turning mid way like a rocket. how do i get the mesh of that rocket to also change direction to the same direction that its going . do i get forward vector and set rotation to that?

[solid zenith]

What I am missing here? Delay node works so position is fine I want my sphere to follow camera forward vector while key is pressed but with timer sphere just doesnt move

[maiden wadi]

Usually you don't affect the mesh at all. The mesh should be parented to the root component which is usually a collision component in a projectile. The PMC or code you're moving the rocket with should turn the actor's root component, leading to the mesh turning as well.

[tight schooner]

IsValid node

[tight schooner]

Can't set a timer on a function or event that has inputs. If you need inputs, then store the data into variables instead

[granite scaffold]

how does this help exactly? i dont care if its invalid, the problem is the return node seems to care

it seems to still return none as expected

but throws the error anyway

[dusk dust]

Ignore that whole thing

I was setting up a question and decided not to follow through

[solid zenith]

You mean function will work like that only?

[tight schooner]

You asked how to properly handle stuff so it doesn't throw errors. If some data could potentially be null, do an IsValid check first before doing anything else with the data. That's the common practice. You should strive to eliminate all errors and warnings.

[tight schooner]

Get the variables inside of the function, not outside. If you want to set a timer on a function, the function can't have inputs

i.e. no input pins on the box at all other than "target"

[mental trellis]

Game Instance isn't replicated

So if you want clients to be able to see it, you need to stick it on something like a player state (you can store it locally on your game instance, but when you get into an actual multiplayer map (i.e. coming from a main menu) you need to copy it to a player state)

[signal hornet]

Thanks so much, I was told to put it within a Game Instance but wasn't aware that it doesn't replicate.

[mental trellis]

And, to answer your other question, when you travel to another level, I think you're going to get an entirely new ui

So you will end up creating your nameplate again.

[signal hornet]

Yeah that's what the guy does in the tutorial aswell

[reef sierra]

Hello, anyone know a tutorial for making an AI destroy obstacle in his path? (if he is looking for me, but if there is a door,wall,ect he destroy it)

[surreal wagon]

I'm trying to remove an item from a tileview but this happens instead

[thin panther]

You havent connected your cast

[surreal wagon]

Yeah I tried to an it doesn't work, in the tutorial he doesn't need to connect it

As Cast to tileview in ue4 doesn't need to be connected

[past hazel]

to use Pose Warping do you need to use Root Motion animations without BlendSpaces?

[spark steppe]

that should only work if you make a childclass of list view

did he maybe do that in the tutorial?

[silk cosmos]

You never selected looping. If you want it to consistently move

[surreal wagon]

@spark steppe yes he did, but i cant right click- pure cast

[spark steppe]

that's quite the answer...

you dont have to cast if you extended list/tile view

so only one thing can be true

if he did a cast, he didn't extend the tile view widget

[surreal wagon]

I dont understand what you mean

https://youtu.be/mcBT7IKuHg8?t=592

Look he does a pure cast

the cast to tileview class does convert to pure cast tho

but it's not compatible

[surreal wagon]

I restarted unreal and now I can do a pure cast

ok

[cyan bone]

Whats the difference between these 2 badboys?
Is segment just a chunk of a line? It seems the Get Point distance to line is for an infinite line right?

Hello! So I have a grab mechanic in my game, and I am using a Physics Handle to do so. The problem is, using a Physics Handle you can only grab components, and not actors. My actor, that is a cube, has collider components identifying which face it corresponds in the cube, and these components are in the way of the mesh, AKA my players grabs the colliders instead of the actual cube

[serene pike]

Trying to reference one instance of a blueprint actor in a level, I'd done it months ago it seems, but I have no idea how I did it, how do I do another of these

[balmy vessel]

Is there a way to set Owner No See in the details panel or do you have to do it through blueprints?

[dire orbit]

Did you figure this out? I can't get it to work

[last abyss]

click on the actor in the level, then in level blueprint right click in the event graph and at the top you have the option

[trim matrix]

is it possible to move spline in the runtime? make it longer, or wider?

Wider?

[supple needle]

Hi all, happy Wednesday,

I have created an actor blueprint that is basically operating as an on off light, push and hold a key and it goes on, release and it goes off. The issue I’m having is if I copy paste the actor the key input only controls the most recently placed actor, what would be the solution to control many actors with the same key input?

[wide solstice]

Hey guys do the "playlist" of audio with concatenator loop automatically?

[brazen pike]

If you're putting the key input event inside the light itself, unticking the box "consume input" on the event might solve your problem, but to really solve the problem you probably want just one input which is handled within the player character and sent to any light the player is looking at / near

But of course, that might not even be your problem, so if it isn't then send a screenshot of the blueprint from one of them here

[supple needle]

Thanks Lemon, ill try this out, not currently at my computer but plan to dig in tonight. Just wasn’t sure where to start.

Will send a screenshot if i hit a wall again

[humble oracle]

How to do so, that game continues after playing the sequence where it was interrupted?

[rich jungle]

Failed to load /Game/World/TileDisplay/CartTileStruct1.CartTileStruct1 Referenced by CartGameMode_C

I did a big stupid and force deleted something because a type change was messing everything up (I couldn't replace the references because I was going from object>actor)

I keep getting this type of error when trying to run the program

thing is

I actually made a new struct entirely and replaced all references to it

but now I'm getting the same error I was with the old corrupted one

does anyone have any experience with this?

(of course the moment I ask I figure it out)

(the corrupted blueprint was a variable inside the "can't load" property. Even though I changed the variable to my new non-corrupted version, it was still bugged thinking that property was corrupted. I had to delete the variable in question)

[ornate hatch]

hey guys so I ran into an issue where the timelines are not reversing, instead stops!

[versed sun]

Reverse from End

[ornate hatch]

doesnt work

it still stops

other half of the function

ohh the bottom part in not connected to anything btw

[cyan bone]

https://blueprintue.com/blueprint/yorl7h2c/
Im trying to make a lerp Event function.
It works fine, but the issue is, its being executed asynchronously.
So it will execute everything after the event call before it is Finished.
So how can i make a function that makes a lerp with a timeline that waits before it finishes, like a function with a return would do?
Since i cant put timelines inside functions. What is the alternative here?

[tight schooner]

Not sure what you mean. Timelines have a completed pin. If you want to queue actions, I guess you need to make a queueing system that buffers the necessary data and waits for the timeline to finish before running it again with the next item

[cyan bone]

100%. But im making this function so it is reusable all over my blueprint. So sometimes the lerp ends and i need unit to rearm. Other times i need it to move then jump. See? So there are different outcomes at the end of the timeline.
Perhaps i could send in the event an argument for a reference for the next function to call after the timeline its done? Is this possible?

[versed sun]

i think Play from start Rotates from (Where it is) to 25,-10,-70, so the reverse is rotating from 25,-10,-70 to ....(Where it is), you need to save the default Rotation BEFORE you start moving it. and do the same for Location

[solid zenith]

What node would allow me to return between two vectors depending on boolean?

[maiden wadi]

Select vector

[solid zenith]

nice ty

[ornate hatch]

ohhhh yah!!!! i forgot about it, I AM SO DUMB

[gentle urchin]

The code you're showing isn't related to your issue , if im reading you correctly

Its like you want to wait for the timeline to finish before execcuting whatever was setup after Play timeline From Start

[cyan bone]

Sorry. Yes this is confusing. In my project i have a lot of timelines with lerps all over the place. So what i meant to do, is to create a function that lerps my character, and then proceeds with whatever it was doing. But maybe this is not possible and i have to just work with what we have, and just use timelines everywhere its needed.

If i could use a function that just lerps from a timeline. Then i could call this function/event from every other place. Instead of making 10 timelines, i would make just 1. That was what i was trying to do.

[gentle urchin]

Why save on timelines ?

having one or 10 shouldnt make any difference

assuming you're still gonnna do the same code anyways

[cyan bone]

ok i came up with an idea. I will post it in a bit.

This is what i came up with just now. So basically this can be reused for all context. I just say where this is coming from and it will then go back at the end. This way i can use this lerp in all places of my blueprint. What do you think? Is this good, or bad practice?

[versed sun]

can you put everything after the timeline into a function ? so new function would have input pins of: Instance, Destinations and Time. Inside your function you can get your Get Current Transform Instances, Get instance Count, the Loop, and Update instance transform

Also, uncheck Mark Render state Dirty for all but the last Index of loop. no need it updating more than once a tick

[brazen stirrup]

hey so question for you guys

im spawning some spheres, but cant add impulse to it

[cyan bone]

How do i do that? The timeline wont allow me to collapse to function, and its in the middle of the spAgheti?

[versed sun]

I will mock one up for oyu

[cyan bone]

Uncheck state dirty? So i make an if statement to check if it is the last one?

[cyan bone]

thank you kind sir

[brazen stirrup]

can someone tell me what im doing wrong with my bps?

[desert juniper]

read the error in your console window

it'll tell you exactly what's going wrong when you try to add impulse

[brazen stirrup]

it says set physics enabled

but im already doing that

any ideas?

also, the target is the spawning actor

[rich jungle]

did you add a movement component to your actor?

[brazen stirrup]

i dont think so, its just a sphere

[rich jungle]

add projectile movement component

[brazen stirrup]

that didnt work

so , the spheres supposudly a volleyball

and i want to add impulse to it

[versed sun]

not sure if it works, but thats where i would start

[cyan bone]

I see that is nice. Thank you. It looks cleaner. But on the other hand i thought that putting the get all instance transform before would save a little bit. So it wont be preformed by all thousands of units each loop.
I will test now the last index dirty render.
But i dont know why this is necessary? Is there an issue in rendering all dirty? Wasn't it supposed to be better for performance because its dirty?

[versed sun]

i THINK if its true, then it refreshes all instances and redraws them,

[cyan bone]

Oh there's that issue, that with the lerp the get instance transform cannot be called every time you lerp, else it will increment the speed like crazy. That would be in Vinterp to? Or am i not seeing something?

[versed sun]

and yes , the the transforms before the timeline would be better

[cyan bone]

So this is cheaper. I didnt know that.

[gentle urchin]

its also a tad cheaper to bulk update the transforms

[brazen leaf]

Im trying to set up a top down camera that I can pan around by clicking and dragging, like you would scroll a map in most mobile apps (if the mouse clicks, then moves down right, the map should move up left at the same rate, and only while the mouse is moving)

I have the mechanics for getting the mouse cursor but Im not sure how to set up this movement

[brazen stirrup]

ok, got it fixed, the impulse was too low lol

[cyan bone]

I tried doing the last index mark render state dirty, and now none of them move. They just stay in the same place. What am i doing wrong?

[versed sun]

yah, instance count -1

[gentle urchin]

I would expect it to work, despite this?

since the loop also ends at count

even if the set index is invalid for the node?

well, perhaps not. It could be one of the first checks, and just quits early

[cyan bone]

-1 now it works. thank you

[versed sun]

Maybe Skip that and manulay check it true just to see if it works

[gentle urchin]

So if the index is invalid, the rest is ignored 😄

[versed sun]

oh, i think the Loops Last Index should be Instance count -1 also

[gentle urchin]

yepp

Still, bulk updating is cheaper, so i'd switch to that sooner rather than later

[versed sun]

batch

[gentle urchin]

yeah, mb

[cyan bone]

I was just working on that and got confused. So basically batch update is cheaper because it wont need a for loop, and will just update them with an array of transforms.
But in my situation i need to do a for loop anyways, because i need to get the Lerp new location inside that transform array?

Perhaps in this case it's that much better?

[gentle urchin]

From my tests it was marginally better , but still better

it's a lot more complicated to setup in my scenario with individual units who may or may not move etc

[versed sun]

Do the Loop part in the function, Save the values to a Local Transform Array, and after the Loops is finished, then batch update

[gentle urchin]

I'm considering a rewrite to benefit from it, but it requires swapping between moving and stationary ISM components

[cyan bone]

Is it possible to make Local Array?

[gentle urchin]

yes

[cyan bone]

The only one i see is that one with the pins

[versed sun]

yes

[gentle urchin]

This is also way faster in c++, about 1/8 of the cost in my setup

[versed sun]

Can you toggle seeing NavMesh at runtime in UE5?

[spark steppe]

guess you have to eject (F8) from the viewport, unless you meant standalone runtime

[glass path]

guys i have a problem with camera shake. When i stop moving, the camera shake starts blending out. So when i start moving again while the camera shake is in the process of blending out, it snaps right back into the start of shake. How do i make the transition smooth?

[versed sun]

ahhh, i didnt have NavMesh Volume tall enuff

[cyan bone]

So something like this? This is not working i dont know why. Its getting so spaghetti 🍝 i can hear the italian music

[versed sun]

Make sure you Clear the Transform array before every Loop

oh , i see it

I haven't used the Batch update yet , so no clue

[cyan bone]

https://blueprintue.com/blueprint/ixo339ch/
maybe @gentle urchin can see what im doing wrong?

[soft peak]

in animation blueprint, i know i can somewhere check a checkbox where it says something like that: "when animation is done allow transition out of current state"
but i totaly forgot where that was?! -.-

[gentle urchin]

Check the return value of the batch update , to see if it gets accepted (true)

[cyan bone]

it says false in debug

but it works with the old update instance transform. so strange

[versed sun]

maybe your Array Length != Instance count ?

[cyan bone]

yes that is the issue. so it must be exactly the same. im doing something wrong very early on

thank you

[versed sun]

being 1 off is so easy to do

[cyan bone]

I removed last index. But now the units might be going to the wrong index place

[versed sun]

remove first ?

or, Last index of your loop need -1

[sly sage]

Hi! New member here. I received this error when playing a level that I'm working on. Any idea on what I need to do to fix it?

[versed sun]

you should be able to click on the text after Node: and it will take you to the problem

[sly sage]

this is where it took me. does anything look off in the blueprint that could have caused the error message?

@versed sun

[versed sun]

yes, where are you setting "Armor"

?

[sly sage]

does this help?

[versed sun]

Is Armor a component or variable ?

[sly sage]

I apologize if I don't understand basic blueprint Logic. I'm a sound designer trying to learn some of these things

[sly sage]

I believe it's a component!

does this hierarchy imply that?

[naive stag]

any ideas why the heck this might be happening?

https://streamable.com/2wdyd6

Im using Move Component To equally both for sky and ground

but for some reason I cant use it on sky second time

While I can easily for ground

[sly sage]

nvm! I found that it's a variable

[supple needle]

the consume input was the issue, thanks!

[brazen pike]

You should really look into setting up inputs on the player character instead, as well though. Inputs really aren't designed to be used this way, which is why consume input is turned on by default. Additionally, if you ever want to do anything with multiplayer you'd have to completely redo this entire system, so it would be beneficial to learn now

[solid zenith]

is there any way to see in runtime how costly my certain blueprint is

like gpu stat or something

[supple needle]

Good to know, currently im using unreal as a virtual stage for DJ sets but anything I can do to make it expandable and more efficient is worth looking into

[brazen pike]

With that you won't have to worry too much about optimisation then. But it does mean if you make something else you wouldn't have to constantly repeat input code, so it can only help

[brazen leaf]

any vector math ppl on? Trying to figure out how to generate a vector for a new camera position given the difference between 2 other vectors.

More specifically, to implement click-drag camera panning, I am getting my initial click coordinate(A), the next tick mouse coordinate(B), then I want to move the camera (C) relative to the difference between A and B, so that I can move C to new location D (I think this will work but my brain breaks at vector math)

[crude isle]

uhh for some reason

when I spawn an actor

it spawns but it's not visible

normally it is visible

and I debugged to check if it was even spawning it and it was

help me lol

oh wait nvm

I found the issue

[naive stag]

What was it

[crude isle]

I was spawning the wrong actor

[naive stag]

Bruh

[crude isle]

wait nvm

it is the right actor

wtf

it's invisible

I can see the scene root

[naive stag]

Screenshot

[crude isle]

but I cant see the mesh

[crude isle]

lmao, there aint really a way to screenshot this

ah

there we go

I fixed it

[winged thicket]

yo, im trying to make animations using bp (i forgot what those things called) and i faced this problem
i have this component i use to.. ughhh.. you can see it in the vid, anyways i use that component to set the leg position
and now when im trying to set its world location it moves to the new location but its X,Y,Z dont change for some reason which make this weird movement, and also makes me unable to set the other things locations properly.

^

how do i fix dis

i just use simple setworldlocation

oh yeah and i do all that in construction script

[cyan bone]

I have a for loop that ends at distance count.
Instance count is 80. And I just push 1 element per instance into another array, final destinations.
I get 81. I only noticed this now because im trying to use Batch Update Transform. Until now i have done many many functions using Get Instance Count.
So...should i go back and and add -1 with get instance count every time i loop through an instance? I dont know why this never gave issues before.

[versed sun]

if your instant count is 80, and you loop from 0 to 80, it loops 81 times

so, if your Last index is Instance count(80) minus 1 (79), it will loop 80 times

[cyan bone]

i have like 40 functions all doing it wrong 😆

ok will fix it all

[sudden zephyr]

Jo.. Anyone know if you can modify chaos wheels at runtime? Can't find a way to access them in my vehicles. E.g. I want to at low speeds enable rear axle steer and no axle steer past some speed. o.O

[dusk dust]

is it possible to get the viewport cameras location? and is it also possible to get it through construction script like how you can get the locations of other objects in the construction script?

[sudden zephyr]

Hm...
https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Development/Editor/GetLevelViewportCameraInfo/

[dusk dust]

i searched this up and its not there

[sudden zephyr]

It might require this in a world BP/level BP or how it's called and then try take the info from there. ¯_(ツ)_/¯

[dusk dust]

oof

i cannot do that in this case

[sudden zephyr]

Why not?

[dusk dust]

my blueprint isnt a level blueprint

[sudden zephyr]

Ofc not.

xD

[dusk dust]

yes

i cannot switch to level blueprint

[sudden zephyr]

What i mean, you can implement something to take the info inside level BP and then pull the info from your actor BP.

Duh xD

[dusk dust]

hm how

[sudden zephyr]

That's what I mean.

Well...

[winged thicket]

yo guys this corner looks very cute in my question up here ^^

[sudden zephyr]

Not sure about that one. Wasn't working that much with levels tbh. Mostly working on actor BP, so, sorry, all I can do in this case is point you in the direction. GL! xD

[dusk dust]

thanks

[dusk dust]

hmm

[winged thicket]

yeah its a pretty cute corner, you should totally go up and see the question :D

[dusk dust]

i did

though I do not know the answer

which is why i did not answer

[winged thicket]

but fr bro everyone who clicks on this channel needs to go up and see this question

[somber dove]

anyone have much experience with editor utility widgets? i'm trying to trigger something on mouse movements, but am only able to capture the mouse movements when they move over the widget, and i'd like to capture the movements when the mouse is on the viewport. any ideas here ?

[faint pasture]

#editor-scripting

[somber dove]

thanks!

[tawdry kernel]

Anyone knows how can I make so that the main char camera dont change when possessing another pawn? Cant find the solution to that

[earnest tangle]

there's an option somewhere to not automatically switch camera when possessing

might be on player controller or player camera manager or something like that

[austere vapor]

I'm trying to create a flashbang effect. I have tried using an actor-owned PostProccessing component, along with UI widgets to create the effects, and while they have both worked, both methods also trigger the person who didnt get flashbanged to get blinded. Does anyone know how to make sure only the target is blinded if they share a class? This needs to works for both online and local multiplayer

[faint pasture]

Show your code

[earnest tangle]

create a dynamic material instance of your PP material and assign it into the camera's PP mat stack

[lavish sphinx]

https://www.youtube.com/watch?v=-WmhLaU8HoU any idea, how can I do that?

[earnest tangle]

as long as you correctly trigger it only on the player in question it should work that way

[earnest tangle]

which thing out of the more than dozen things happening in that video might you be referring to lol

[grave apex]

does anyone know how to jump to where an asset is specifically being used within another one from the reference tree?

I cannot find where that voice clip on the right is being played in the MyButton widget

[austere vapor]

I'm away from my computer atm but it's the simple "create widget -> add to viewport"
with the widget removing itself after the animation is over

[crystal torrent]

that point, how to make that point launch the strokes and make them collide with the walls.

[earnest tangle]

🤔

Might be a particle system of some variety

Although it also looks like the debug lines you get from linetraces

[tawdry kernel]

Yeah but does not work properly. When you disable that and possess another pawn the engine creates another camera on the middle of the possess pawn

[earnest tangle]

I don't think you changed the correct setting, there's one which just stops it from doing anything with the camera when a new pawn is possessed

Unfortunately I don't remember where it was specifically or what it was called, but I'm fairly sure it was somewhere in player controller, the camera manager, or other classes related to those

[sudden zephyr]

Should be rather simple me thinks. It runs the camera separate from character. You set the cam location manually and to ensure the smoothness, I'd even detach the camera on being play. Then set the camera with lerp/interp at what ever distance in the direction the char moves, have a line trace at feet level + bit above that (floors and what not) in a 360 circle and stop updating camera movement for that 'direction' that it hit just to ensure smoothness or if you'll have some 'environment' stuff that moves eventually in game. Don't just stop camera movement. Hope you good with math tho, gonna need a bit of it to pull off but should be rather straight forward. Not saying easy or simple, but very straight forward. 😅

[sudden zephyr]

?

Perhaps this?

[tawdry kernel]

this on the controller?

[sudden zephyr]

Actor itself but might have override settings on components too so, here's a nice trick

xD

So, just search the component too and see if there's a cam posses setting and uncheck it. ¯_(ツ)_/¯
GL! 🙂

[earnest tangle]

    /** 
     * True to allow this player controller to manage the camera target for you,
     * typically by using the possessed pawn as the camera target. Set to false
     * if you want to manually control the camera target.
     */
    UPROPERTY(EditAnywhere, Category=PlayerController)
    bool bAutoManageActiveCameraTarget;

try this one, it's on Player Controller :)

[sudden zephyr]

Thought so... I assumed a character component would have an override for sure.

[tawdry kernel]

Im using blueprints, but I will try that

[earnest tangle]

Yeah it should be available in BPs too

You just need to create a custom player controller class if you haven't done that, and select it as the default

[tawdry kernel]

ooh yeah, Ive found that bool

it does not work the way I expected

it still creates an Camera attached on the possessed pawn

[sudden zephyr]

Did you also disable the one on actor itself too? Just in case.

[tawdry kernel]

that bool is ony avaible on the controller

available

[solid zenith]

Alright what is wrong here I dont get it bruh first sound deactivates perfectly fine but second one suddenly throws error that apparently sound is pending kill or garbage whatever it means while the sound is still playing

bottom white line is on E key pressed top one is on released btw

[sudden zephyr]

I remember having some issue with that too with character/vehicle bp's and what I did ultimatiely was get the position of cam before switch and on begin play detach the cam and set the location to the previous cams location. So... Yeh. xD

[manic osprey]

How would I create a lottery winning scratch card system where the player can scratch cards ?

[tawdry kernel]

a way that Ive found to somewhat fix my issue was using a camera maneger on the player controller, it does not change the camera, but when I move my cursor the camera dont move

when I possess a pawn

[mossy abyss]

Hello all, quick question, would anyone have a clue as to why multiple timelines would proc when they are on separate events in the level BP?

[sudden zephyr]

Dunno what you're trying to do and hence we don't know which one might be the best solution. However, I think camera manager is so to speak an interface, it's done by you, you're basically telling the engine 'don't let components or actors interact with camera unless I want them to.' I think. If someone could confirm. Haven't played around with it in a long time so...

proc? 😅

[tawdry kernel]

what Im tryng to do is controlling a submarine inside of the submarine, its a firts person game

but I wanna be able to move the submarine without changing the main char camera

[sudden zephyr]

Well, did you actually do anything with the camera manager/player controller or did you just make new PB's and connected them and that's it?
Cuz now you gotta tell trhough player controller which pawn should take input from which pawn and what not.
Again, the entire point of it is so you have absolute control over it.

[mossy abyss]

Sorry for poor nomenclature, out of 10 timelines that play the last two seem to also trigger prior timelines in tandem.

[sudden zephyr]

Unless somewhere in code the event re-triggers because of changes done by those timelines, those timelines don't activate them otherwise.

[mossy abyss]

this is an example of the second to last timeline, it boggles me because like you stated it shouldnt be happening.

[sudden zephyr]

I didn't say it shouldn't be happening, I'm saying that on the SC, no timeline can possibly re-trigger anything by themselves as seen there. So that chain is fine. However, if something, let's say a piece of code somewhere that checks the actor location triggers that timeline chain, right? If the timeline chain does something to make that prior code trigger the timeline chain all over again, then there's the issue.

So what you could do as test is, add a bool to the event with whatever name you think appropriate like DONE? and make it true by default and if true and add a branch just after the event that gives you issues. after the branch set bool to false and make that bool set to true after the last timeline should finish.
If you get the idea.

Although you should definitely check what causes it and fix it, sometimes some things also need this be default no matter what. It's based on what you're trying to do. Some actions can retrigger and this makes sure that the first action finishes before it let's it do another one. Normal stuff honestly. So, depends on whatever it is your coding. Hope this helps and GL! 🙂

Oh, and the names are trademarked, you can't use them 😛

[mossy abyss]

I appreciate the suggestion, and will be sure to credit you for your assistance, as this is an academic project!

[sudden zephyr]

Please don't LMAO xD

[mossy abyss]

I shall honor your request.

[mossy abyss]

Implementation is a bit different, but it worked like a charm. if you were curious though its a rail shooter so timelines were easy.

[dawn gazelle]

When you press E, you're spawning a sound, then delaying for almost a second before creating the second. On release, your code shows that you're trying to toggle them active. If you press E and immediately release before the delay is up, then the second "Toggle Active" won't have a valid reference to the second sound you're spawning.

To fix this, you may want to store the references to those sound components as variables and you can use a validated get to check if they are valid before attempting to toggle active, just in case it wasn't created.
It's also generally a bad idea to take references across execution lines for just such a reason - you're making an assumption that the return value is going to be valid when that part of the code may not have executed yet.

[sudden zephyr]

Isn't spawn sound playing automatically?

[dawn gazelle]

Yeah but the "Toggle Active" node can stop the component I believe. So press E, it's probably supposed to play the sound, and on release of E it ends up stopping it.

But if the sound component isn't created, then he'd get the messages indicating that it's not a valid reference or pending kill.

[solid zenith]

thx for response but I fixed it with using "is valid" node on key released and if its valid just deactivate that sound lol

[sudden zephyr]

Toggle is a bad way of doing things that need specific start/stop

The whole thing is weird, that's why I'm wondering.

[solid zenith]

how do you play sound then

but be able to cancel it

anytime

play sound doesnt let it

[solid zenith]

aaa thx will try that

[sudden zephyr]

Basically, no need to spawn it before you want it to actually play, uneccessary I think. So you can just spawn it at the "toggle" part and stop it there, that way you don't need to store references, less variable clutter, however, you do need a validate in case the sound finishes before it should call "STOP"

Especially if you have the "auto destroy" checked.

This is what I mean:

No need to store references if it's very temporary. Again, depending ofc and assuming by the pic. 🙂

Oh, to make it easier, basically, literally replace the toggle node with the validate and stop node as shown

What you're basically doing is, 'if the sound exists, stop it, otherwise it's already done, move on in the exec chain.'

[solid zenith]

lemme try real quick

tho where would I connect on key released

to stop the sound

[sudden zephyr]

Literally replace the toggle sound with the valid/stop nodes

[solid zenith]

oo

I do that already then

[sudden zephyr]

Should work then. xD

GL!!!!!

[solid zenith]

is valid? branch if true stop it

ya Ive got I think harder one more question

tho lemme screen record rq

[sudden zephyr]

the is valid should go in stop, the no valid should go to branch or whatever the next node is

[solid zenith]

ya it works like that tho u mentioned something its a bad way

actually nvm

u said toggle

lol 3am here

[sudden zephyr]

Nah, nvm, didn't comprehend at that moment. xD

4:30 here. B)

[solid zenith]

Look at this those particles will be position my character gonna teleport to, Im almost certain half of teleports will end up inside objects cause it doesnt avoid them, rn im doing it with line trace and camera forward vector but without adding tons of spaghetti and like 12 more line traces and math I dont know how to make it avoid all holes like this

[sudden zephyr]

Should not be that difficult actually.

[solid zenith]

Ya cause I probably do it the stupid way

[sudden zephyr]

No, not really.

[solid zenith]

well my way I only imagine shooting into all directions more line traces and push position accordingly

and I even idk how it gonna run cause its on event tick

[sudden zephyr]

basically, shoots a line trace from camera forward, and on the impact shoots another one upwards until a gap is found within a threshold. If it's clear within that threshold, have an offset from the (edge) and shoot one last line trace upwards that checks if there's enough room for the character. That's pretty much it, I think.

[solid zenith]

actually u gave me better idea

i just shoot down and up if even one is not enough just show u cant teleport there lol

[sudden zephyr]

One think I'd say to first do to make it easier to check what it's doing is to have it change color, like red no teleport and green teleport and it's gonna also make it easier to see what the code does/thinks is valid. It might be janky when it doesn't find suitable teleport location but you don't care for that as long as it's not janky when it does.

I'm assuming the teleport only works on surfaces the character can actually stand right?

[solid zenith]

actually I dont know how it would work if I do that inside those white cubes from video it would hang up shooting up and down unless I misunderstood

ya

[sudden zephyr]

Let's say a pole? Like the street lights in Dishonored.

[solid zenith]

oo it doesnt mean it can stand there

he can fall or whatever

just to not teleport inside small hole

[sudden zephyr]

No, I mean the initial teleport should allow thin geometry or only wide ones, that will determine the ledge depth threshold

[solid zenith]

in simpler terms if u can lmao

[sudden zephyr]

Literally just needs 3 line traces, however, the threshold implementation is the issue. xD

[solid zenith]

My character just has simple default capsule hitbox nothing fancy

if u talking about that

[sudden zephyr]

That's not really important.

No, the threshold of if there are 2 possible teleports close to eachother and you want the player to be able to select them.

[solid zenith]

aa you thinking something hard

I just want position to get out of hole

2 possible teleports shouldnt be a thing

[sudden zephyr]

Wait, is it something temorary or is teleport part of the main gameplay loop?

[solid zenith]

temporary press E see position u will tp to release E teleport

its a skill in the video im holding e all the time

[sudden zephyr]

Nvm, you don't get what I mean.

[solid zenith]

Alright I just checked out your big words and my stuff is definitely main gameplay loop

first week in ue5 tons of weird names for everything dont really understand ue5 slang yet haha

[sudden zephyr]

Ah, np. Asking because it it's temporary, it's easier to do with triggers for ledge detection, but if it's main loop and should be dynamic and not rely on assets with triggers or other info, then what I said earlier, 'detect ledge' will be first hurdle and easiest, you got it almost down anywa, but you'll have some trouble with the detection threshold what I call at least, not sure if there's an actual name. What I mean by that is this: Old vid/old project in UE4 btw. If I find the project, I'll send the code but I doubt that. T.T
https://streamable.com/nosmbp

If you notice, theres 2 poles close enough, now you want that 'what I call threshold of which to pick in close proximity'

That one was a PITA xD

And yeh, I borrowed a hunter from HL2 xD

[solid zenith]

your teleport is very different of mine but anyways I will leave this for now gonna come back to it when I understand more haha thx

[sudden zephyr]

Actual shame, had a fully ported hunter and strider. T.T

The point is not the teleport however, I just interp and you won't. But yeh. GL!

[solid zenith]

this right here

I can assure you with certainty

I dont need that

and u use video as the visualisation of what you mean

[sudden zephyr]

Oh... Then it should be really easy no? Literally just 3 line traces lol

I'm guessing ofc. o.O

[solid zenith]

I cant imagine just 3 line traces would cover all cases

[sudden zephyr]

Well...

I mean, is it a multi orientation teleport or just teleport on top of things?

[solid zenith]

u will always teleport with current orientation just position has to be pushed out of any holes where you wouldnt fit in

[sudden zephyr]

Yeh, hense 3 traces, 2 for ledge 1 for height/hole if char can fit.

[solid zenith]

alright u shoot one forward hit 90* wall shoot one up hit wall too, shoot down hit wall too, its a hole

what do we do

[sudden zephyr]

A 90 degree wall is a floor but yeh, if you have a location on your level to show, that'd be easier. 😅

[solid zenith]

how do you get position just outside of this box as simple as possible

that would cover any hole

[sudden zephyr]

What you mean outside? On top? On bottom? What's the priority?

[solid zenith]

actually good point I cant say nearest possible position I would fit in

but it could be behind it for all ue5 cares

towards me

ig

[sudden zephyr]

It should be based on where the player is looking.

IMO, your choice however.

Theres 2 possible approaches, one is harder (i did that) and one is slightly easier. One includes triggerboxes that you can place manually to tell the teleport system where it can and cannot teleport, one is the harder where it needs to recognize that by itself.

[solid zenith]

trigger boxes would be fine I think just gotta look up how it works

tho I dont see any tags system like in unity

in unity i did something similar

just said ignore certain tag

like shoot through it

all the complex shapes were in it

could hit only basic no problem shapes

[sudden zephyr]

Trigger boxes are pretty simple to setup. Basically you put a trigger box with custom channel collision for 'can teleport' and place it where you want, then one sphere trace shoots out of camera and if it hits a triggerbox, it enables the teleport. That is the 'static' way of doing it. AKA how Dishonored does it, i think. A more dynamic way, like in Dying Light for instances uses a fully programmatical approach instead for obvious reasons.

Ofc it can be a combo as well. 🙂

[solid zenith]

Could I place those boxes

and they would act like hits

[sudden zephyr]

I think so

[solid zenith]

ya its good then will do them

[sudden zephyr]

LMAO, where is the add objects now in UE5? I didn't even get to place a single box yet and dunno where it is. xDDDDD

Oh, and by trigger box, ofc I mean, you setup a teleport channel in project settigns collision, you make a actor BP and add a trigger box in there and set it's collision to teleport channel. Then a sphere trace by channel to hit the teleport collision channel.

And you can even add a custom thingie that denotes a teleport box ofc and you should do that from the get go, thank me later. 🙂

[solid zenith]

Ya thx

[sudden zephyr]

Basically any triggerbox should have a specific mark or you'll be crying later. I know I did. xD

Oh, to avoid confusion, in actor BP, you're looking for box collision and billboard for custom viewport 'icons'. If someone wonders. 😅

[trim matrix]

any idea how to set the bounce angle of a projectile?

[sudden nimbus]

let physics do it

[trim matrix]

how?

[sudden nimbus]

if you configure the projectile to collide with the target, it will do it on its own

if you are not seeing that, it's probably missing the collision because it's too fast. CCD (continuous collision detection) is one way to address that

it's not enough for all use cases, but worth looking at

[trim matrix]

I'm trying to recreate pong and the problem is that if a projectile collides on a perpendicular surface it loses all angle and just bounces across one direction

Whereas normally you'd want to add a 45° angle to whatever angle it bounced at

[sudden nimbus]

you mean it hits at 45deg, bounce in the 45deg angle with the inverse of the surface it hits

pretty sure it should do that fine. Are you applying a force on hit or something?

here's an idea, are you modelling the 2d circle as a sphere ?

[trim matrix]

Yea it's a normal static mesh sphere

With a projectile movement

no friction, no gravity, 1.0 bounciness

[sudden nimbus]

try constraining it's z axis, even though I assume you are doing an orthographic 2d camera, it would still matter

[trim matrix]

z axis is not an issue because it floats above the ground and has 0 gravity

[sudden nimbus]

that doesn't constrain physics. There is properties for constraining physics in particular dimensions as well which would be even better

kind of sounds like the Z of the ball is going crazy, and maybe you don't notice because of the orthographic projection?

on the other hand maybe if you started from a 2d template all of that is handled /shrug

[trim matrix]

I mean if I spawn a simple ball, give it a projectile and initial velocity, 0 gravity / friction and point it at a wall at a 45° angle

shouldn't it just bounce back at the same angle?

[sudden nimbus]

I'm suggesting that things are happening in 3d that you don't realize, so "45deg angle" wouldn't have a meaning without some kind of reference axis

but again, if you started from a 2d template to build this pong, I'd imagine constraining things the right way wouldve already been there. I've never built anything 2d in engine

[trim matrix]

Figured it out

it was the friction set to 1..............

But why would friction kill any angular momentum?

I thought it was normal behavior so I spent 2 hours developing custom bounce logic relative to the angle and position of the racket

-_-

[sudden nimbus]

I feel satisfied that I nudged you to make the physics engine work for you, rather than reimplements the physics engine :-D

even if that's completely not the place I suggested to look, ahem, it's fine psssh

[gentle urchin]

Close enough!

[sudden nimbus]

close enough is 5.0.2, PSA: problems with ue5? update to 5.0.2, there's 300 fixes in there and you should have them. I for one am weeping with joy

[gentle urchin]

Where does the umg listen for input locate on the input stack? Is it equivalent to an actors 'enable input'?

[grim lantern]

How do I create an array of Transforms on the fly in Blueprint (Without creating a local variable)

[gentle urchin]

Make array

Why not make a local variable?

[gentle urchin]

holy , thats one big update

[oblique shore]

Does any have tips for making a 3D fighting game like Tekken or Soul Calibur?

[gentle urchin]

Those games feel closer to 2d than 3d

[jagged stone]

How would I check if an actor (for example "Other Actor" from a overlap event) is a player character? Do i try to cast it and check for failed?

[fiery glen]

Sure

[worthy tendon]

no need for cast, just use GetPlayerCharacter node and compare it with Other Actor using == node and a branch

[jagged stone]

But I mean it can be any player character (so in my case 4 local players)...it would seem ineffient to loop through all 4 and compare?

[gentle urchin]

On overlap, would you care which one tho

Casting solves this easily

If you care which one then youd probably be easier off having some integer for them, and read the int from the character that overlaps

[jagged stone]

Is this an acceptable way to do it?

[brazen pike]

Yes

[jagged stone]

So if someting not castable to that overlaps it just ignores (it doesn't throw errors somewhere?)

[brazen pike]

It would execute the "cast failed" line, which if you have nothing there does nothing

[jagged stone]

ok thanks

[still rain]

spline went pink and not editable, has anyone encountered this before/

[winter cradle]

Hey there, I'm having troubles with setting a custom data value on a HISM , can anyone pls help me understand why am I getting false here? It should be very straight forward but the value isn't set

[serene bramble]

Any help?

[icy dragon]

Plug in a static mesh getter on that

[serene bramble]

Odd that I've never had to do it before but thanks

[tame pecan]

Yes you have

[serene bramble]

Well it's worked fine w/o it for a while

Maybe I am remembering wrong

[gentle urchin]

Any intel on this? I suspect something is catching my input before i want it to, but not sure... 😅

[sudden nimbus]

#blueprint message

it's hairy

[gentle urchin]

It doesnt explicitly say , ugh

Hairy indeed

It worked like 2 iterations ago, but stopped working during refactoring 😅

I suspect an actor is added to the stack after the listen event in the widget

[sudden nimbus]

yeah that seems possible

as I mentioned in that thread, I've let the player handle global events and it's worked for my use cases, but the person particularly was looking to handle things like main menus where there is no player controller in action

[tame pecan]

Yes you are, there’s no way it works without a target

[maiden wadi]

@gentle urchin UMG gets input via focus If not in the focus path, inputs in UMG aren't processed.

[gentle urchin]

Even with Listen for Input?

I was sure i just used it without it being in focus, but now that you mention it, I did some changes there

[maiden wadi]

Oh, the new UserWidget stuff?

[gentle urchin]

Relatively new yes

[maiden wadi]

Let me double check but if I'm not mistaken those are just InputComponents, same as any other actor, yeah. They'll get put to the top of the input stack, so would stop other input depending on when they were pushed to the stack.

[gentle urchin]

Thats what i was hoping/fearing 😄

Is there a way to see the current input stack?

[maiden wadi]

Hmm. Maybe. Would be easier with a C++ source build. But lets find out.

Well. It is easy to find it in a breakpoint in Player Controller.. but reading through that is annoying.

Lets try something else.

[gentle urchin]

Is it an accessible array or smth in the playercontroller?

[maiden wadi]

It's CurrentInputStack

It uses that to build the stack in the BuildInputStack function.

[jagged stone]

Does anyone know how to get the value from the "Morph Target Object Reference" (I'm looping through the "Get Morph Targets" node which returns an array of morph targets)

[stone flume]

How on Earth can I get the local ip address in Unreal Engine?

[jagged stone]

But how to do get the value from the array element?

[maiden wadi]

@gentle urchin If you just need a vague overview of the input stack. You could run this in your player controller.

for (TWeakObjectPtr<UInputComponent> LoopInputComponent : CurrentInputStack)
{
    if (LoopInputComponent.Get())
    {
        UKismetSystemLibrary::PrintString(this, UKismetSystemLibrary::GetDisplayName(LoopInputComponent->GetOwner()));
    }
}

Remember that this is backwards. 😄 So bottom would input fist.

[gentle urchin]

Hmmmm

"Showdebug input" in console

Forums still have gold in them

It appears to be sorted here

[maiden wadi]

I'm not sure if I'm a fan of the inputcomponents in widgets or not. I Can see some uses maybe. Feels a little weird. Maybe it's to allow better BP access to controls in widgets?

[gentle urchin]

I agree

im gonna move away from it again

just iterating on setups, and getting new directions along the way

picking the road of least resistance 😄

[maiden wadi]

I dunno. I admit I'm too used to the current way. I like that Slate/UMG can completely override gameplay aspects. Make popups and full screen widgets much easier to handle.

I do wish Epic would make a BP pass for some simpler helper functions though. Not sure why flush input keys is strictly C++ only.

[gentle urchin]

Weird how when i move it to the actor it instantly works

So it appears it was at the top of the stack

But still blocked by something. Tried enabling / disabling focus etc to no avail

Oh well, actor it is !

[vivid vapor]

Anyone else run into the issue where you can use a controller in the editor to move the camera. But when you enter PIE you can't move the character?

[gentle urchin]

Not sure what you mean

Theres a huge diff between editor and ingame

Only natural for they to differ?

[vivid vapor]

Yeah sure but the default character in the third person template has mappings for controllers.

Doesn't seem to detect it properly though

[maiden wadi]

Sounds like the editor has gamepad handling, and your game code does not.

[vivid vapor]

I changed nothing and suddenly it detects input

So something was weird with unreal. I didn't even restart the editor.

[maiden wadi]

Viewport focus issue maybe.

[gentle urchin]

Common

[maiden wadi]

Viewport might not have been processing the inputs until you clicked on it or something similar.

[gentle urchin]

I get that all the time

Annoying as hell

[vivid vapor]

ah yeah that may have been it 🤦‍♂️

Ive used unreal since 2014 but I have never used a controller in anything I've made 😛

[gentle urchin]

Same lol

And now i hate every minute of it 🤣

[maiden wadi]

Good luck when you get to UI stuff.

[gentle urchin]

Ui is the worst

For keyboard/controller navigation

[vivid vapor]

Not making a full game thankfully. But I am very familiar with the hell that is UMG.

Thanks for the help guys

[maiden wadi]

Just keep in mind that Unreal was designed around the idea of simplistic FPS/TPS games. You do anything else and you're looking at quite a bit of framework.

Also. Fun tip. You'll notice that most Unreal applications don't refocus the game after alt tabbing. Easiest fix in the world in C++.

[gentle urchin]

Annoying how focus doesnt follow hovered state of buttons. And the navigation seem... half auto?

[maiden wadi]

That's also an easy fix. 😄 OnHovered, set focus, and in the style, add a || IsFocused to the IsHovered check for it's display.

Need your own UButton for that though.

[gentle urchin]

Yee

[maiden wadi]

I did that with my inventory. Modeled it a lot after ARK's. Hover sets focus, allows the button itself to catch keyboard events just from hovering.

[gentle urchin]

And theres no delegates for when the default button recieves/lost focus

Custom buttons solves this

But i dont get why hover/focus is not equal

Why would they differ

[maiden wadi]

I think it depends on the scenarios and designer. Personally, I wouldn't differentiate them in most cases.

Some people want hover displays without focus changing though for mouse users.

And 80% don't even understand what focus is, so..

[gentle urchin]

Me included lol

Started toying with it yesterday

Seeing what works out of the box

Somehow some nearby buttons work out of the box

While further away were ignored

[maiden wadi]

How so?

[gentle urchin]

No clue yet

[maiden wadi]

As in focus navigation?

[gentle urchin]

Almost like theres some internal distance check for a focusable widget in the aproximate direction

Yeah

[maiden wadi]

Most of it is based on containers. Much easier to navigate in grids/hbox/vbox sort of things. Canvas are eh. Usually better in canvas to override the escape functions to specify specific widgets.

[gentle urchin]

This was in canvas, which is why i was so surprised

Had 0 expectations to it

[maiden wadi]

I would definitely recommend checking out the escape overrides. They'll make gamepad/keyboard arrows nav insanely easier.

[quaint nova]

How do I make the player max speed go up when an integer hits a certain value?

[maiden wadi]

Run a function when you change the integer. If Integer is value you want, change speed.

[quaint nova]

alright, thanks

[past hazel]

how to select a skeleton for several animations at once?

[cyan bone]

@gentle urchin I think you told me yesterday that using mark render state dirty only in the last index is better for performance in the Update Instance Transform. But in the Batch Update Instance Transform i should tick it right? Because there is no way to do it only for the lasT?

[gentle urchin]

Yepp

It handles it internally

If you batch updated several timed in a frame tho, youd only check it on the last call

[cyan bone]

thank you

[gentle urchin]

Hows the perf looking? Stress tested it yet?

[signal hornet]

Hey guys, I've made a 'Set Overhead Nametag from Main Menu' System. The host can type their name in from the Main Menu, hit start server and it'll load the level and be displayed correctly clients side. However when another player types in their name and hits joins server it overwrites the hosts 'Player Name' with their own text and both the host and client can only themselves as the set 'Player Name' while the other players are unset (which should be a replication issue). Do I need to use an integer to differentiate the players by hooking it into the Save Game Slot & Load Game Slot nodes to make them unique?

[cyan bone]

Its looking good. I will stress test it with a lot of units soon and show it 🙂

[gentle urchin]

#multiplayer ?

[signal hornet]

True

my bad

[shut fiber]

I'm trying to do exactly this. Does anyone have any suggestions?

"Set Editor Property" seems to only be for assets, not actors.

[gentle urchin]

Bulk edit via matrix ?

[shut fiber]

No I need to do it in an editor utility

[gentle urchin]

Guess theres the c++ road then

How do I get the bounds of a mesh when it's rotated? Currently when I get the bounds of a rotated mesh it creates a bound box around the mesh that is still oriented in a 90 degree field.

[shut fiber]

That's just how bounds work - I've had the same issue

[foggy escarp]

Hey, I'm wondering if somebody could point me in the right direction.
I'm developing a physics-based build system and one of my sought-after features I'm planning on including is saving and loading prefabs. These prefabs would include the combination of components and/or child actors. They'd be constructed and assembled in runtime.
Everything is already based on structures and I plan to use data tables in the development.

[untold fossil]

https://gyazo.com/d244965078f088e8a6519fcbc3d99f72

So there is no way to get the correct rotated bounds?

That seems kinda silly

[foggy escarp]

But my question is about how I'd save and load them.
I was thinking about a possible solution of using save objects but im unsure.

[shut fiber]

I'm not very good at vector math but you could maybe store the unrotated extent and then rotate that as the mesh is rotated rather than using the "Get Mesh/Actor Bounds" function after the rotation has taken place

[untold fossil]

hmm yeah could try that

im bad at vector math as well though 🥲

[foggy escarp]

From the static mesh actor itself, you can create the rotated bounds.

one, sec i found something on this a while back

[untold fossil]

@foggy escarp do you mean this? https://gyazo.com/8e8eeb14b3a7a73a53c622191dc8dad7

But what do I do with min and max? o_O

[foggy escarp]

min and max are your extents of the bounds

[untold fossil]

aha

ok lemme try something then

[shut fiber]

Would that not have the same issue though?

[untold fossil]

wait a sec

may have found a solution

[foggy escarp]

https://forums.unrealengine.com/t/oriented-bounding-box-from-getlocalbounds/241396 here's the forum post i used.

There's are multiple ways.

This one is what i used.

[foggy escarp]

You can use the bounds of the mesh or even the imported bounds and orientate by rotation

[shut fiber]

Nice, thanks for sharing

[foggy escarp]

np

[untold fossil]

found it

sharing solution in a sec

https://gyazo.com/699580d833d5871c557e4d69e279ba90

So what I did is indeed first save initial bound extent. Then when rotating I use the live origin of the mesh, the old (saved) extent and the live orientation

[thorny rover]

Hi. Question about level streaming. If you have a Persistent Level and Sublevels under it. For example a ground is in persistent level but houses are on different sublevels. How would you access variables of sublevel elements during runtime (e.g. when the ground is the persistent level but you would need to access a variable about one house)? Ideas would be helpful

[thin panther]

Just as you would any normal bp

If you are talking about communicating between level blueprints im not sure if thats a great idea

[thorny rover]

I would rather avoid using level blueprints

[thin panther]

Well then you can just go about regular inter bp cimmunication

Once you have a reference, cast to it

[opal rampart]

Hi people, I'm trying to teleport my character if he gets stuck falling mid-air, like in Elden Ring (where it kills the player). In the image above, I placed character movement, is falling and teleport. But I don't know how to put a timer, or something like that, that tells the blueprint to teleport the character if he is falling for x seconds. Does somebody know how can I do that?

[wicked osprey]

Guys, how can I rotate an item if it is a root component? I need to select rotate for some items that I will throw away (for example, rotate the weapon by some angle, and leave the first aid kit in the same position, for example).

[earnest tangle]

to rotate the root you rotate the actor

[wicked osprey]

But i have root static mesh, and it simulate physics

[earnest tangle]

so?

[trim matrix]

I have a really annoying issue.. sometimes sporadically my MaxStamina Value here somehow gets evaluated as zero which breaks this logic (division by zero):

It gets fixed when I change anything in this blueprint -> compile -> rechange it and compile again. Why does this happen?

[foggy escarp]

You don't have anything on construct?

[trim matrix]

Its derived from a C++ class and both in construct and begin play it is set to non-zero.

[wicked osprey]

@earnest tangle If I simulate physics with static mesh, then the root component will not simulate it at all and will remain in one place

[earnest tangle]

you're saying that your root is a static mesh which simulates physics

but you're also saying the root will not do that

so I'm not quite sure what exactly it is you're doing

[foggy escarp]

Is your root mesh a static mesh?

if so, then things should work as expected.

[brazen leaf]

Can I make a library function that just takes a generic/wildcard input like Array?
I want to make a helperfunction like Print Array that doesnt care what the type of the object in the array is

[earnest tangle]

you can do it using a macro library but that's about it... it's possible in C++ but not trivial there either

[solid zenith]

This should run on key released but from atleast printing the number seems like get input key down resets to 0 before check comes through how can I fix that? Should make something that holds time then resets and starts increasing only after key is pressed again, idk what to use tho

[quaint nova]

i have this function that should add 600 to max walking speed when my points hit 100 but it just begins accelerating when points are not at 100

i'll try adding it in another bp

[desert juniper]

delete the sequence

sequence just means
'Do this, once you're done, do this'

[quaint nova]

oh

i tried to use it like a splitter so i could use the same block for 2 things

[desert juniper]

yeah, there are no 'splitter' nodes

[quaint nova]

yes

oh my goodness

i did something and now it works

well how do I get more milestones than 100

[desert juniper]

?

[quaint nova]

so in the code currently when my points get to 100 it adds 600 to max walking speed

so if I want to add 600 again when I hit like 1000

should I just continue the set max walkspeed node

[desert juniper]

you could use a select node

https://www.youtube.com/watch?v=lcN-hRux4cU

[quaint nova]

thanks

so if I use the select node with integers, and plug an array with all integers I want it to add 600 to max walk speed with, would it work?

[desert juniper]

know what.

i lied. sorry

[quaint nova]

it is ok

[desert juniper]

an Switch on int node is what you'd want

actually i don't know if you can set specific values

[sharp fox]

where can i post a world/material problem

[quaint nova]

I am watching a series from Virtus covering the endless runner game I am currently trying to make, but he had the speed increase by every tile but I wanted it to be like by hitting a certain amount of points

[gentle urchin]

I'd suggest making a function in the player bp itself to handle the increase

[desert juniper]

after some googling, people suggest a ugly way, of converting the int to a string, and then switching on that

[gentle urchin]

Your issue now is the sequence node, and the consequential flow control of it

[quaint nova]

it is currently in character bp

and the sequence has been removed

[gentle urchin]

Its bypassing your branch, so the branch serves no purpose

If its in the char, why do you get player char and cast to self?

[faint pasture]

Just select speed given points

[quaint nova]

sorry I am an amateur

[desert juniper]

kinda ugly, but is simple and it works

[gentle urchin]

Whats this fir

For

Looks like a bad idea

[faint pasture]

Fuck a switch, just select the speed. It's just a stepped function lol

[desert juniper]

he wants to apply different char movement speed based on number of points

it is a bad idea for sure. but a simple one

better would be map of points to speed

[faint pasture]

And when points are 101¿

[gentle urchin]

Or 99 again

[desert juniper]

100 sets it to 600 speed, and then doesn't care anymore until it hits 600

that was the intention

he doesn't want it continuous. just as an achievement

[quaint nova]

yes

[gentle urchin]

Hard to tell imo

[desert juniper]

when you hit 100 points, set speed to xxx, then when you finally hit 600 pts, set speed to that

[gentle urchin]

But then it'd work yes

[quaint nova]

oops I wrote it wrong

[desert juniper]

ugly I admit.

[gentle urchin]

Well

Alot of default outs

But does it matter

[solid zenith]

.

[gentle urchin]

Probably not

[desert juniper]

@quaint nova is added speed always going to be + 600?

[faint pasture]

As long as 100 is guaranteed to be hit, sure. We know nothing of his points setup though

You want a curve for this.

[gentle urchin]

I guessed point being health points, but if its accumulated points of something, then..

[quaint nova]

yes it is supposed to work like when you hit 100, the speed gets increased by 600, when it hits 1000, the speed is again increased by 600

[faint pasture]

And carrying on?

10,000?

[quaint nova]

yes

then 50000 and then 100000 and 500000 and finally a million

[faint pasture]

Why not 500?

If it's not a steady pattern then use a curve.

If it is then use math

[quaint nova]

well it is quite close since you gain points almost every tick

so it doubles so fast

[faint pasture]

Curve

[quaint nova]

yes

[gentle urchin]

You could hard code a formula but that'd be even worse than the switch 😄

An array of target points

[faint pasture]

The switch is practically guaranteed to never be hit, he said he has points going up on tick, there's no way I would rely on having points be exactly the value instead of greater than the value

[gentle urchin]

Lol i missed that part

thats horrible then

exactly, greater than

[quaint nova]

well

it does increase the speed on 100, but I cannot see currently clearly if it does it again on 1000, I will come back to this when I get some obstacles

[faint pasture]

Dude just do a curve. This is shitty and will break all the time.

Also why are you still getting player character and casting to third person character? Isn't this ON the third person character class?

[brittle garnet]

This is self-harm. Please stop.

[zinc flicker]

Question about "Groom" hair and enable/disable simulation.

Since groom hair take lot of performance i was thinking to make them only simulate when you walk over a trigger box and are near them so they got deactivated for the rest of the time.

The problem is in the image above the "simulation enable" from groom, doesn't work at all.

The only option i found for now that worked is just to make the hair "hidden in game".

Is there a way to tell the "groom hair" to disable and enable simulation or is the "hidden in game" way to go?

[quaint nova]

so do you mean float curve or? (I know this might be a stupid question)

[faint pasture]

Yup. X axis is score, y axis is speed

You can make it stepped and not smooth so it only goes up at the break points

[quaint nova]

yes I did that

How do I reference it in bp

or something

@faint pasture

[faint pasture]

Add a float curve variable to the BP, set it to be the one you made. Then sample it (Get Value at Time or whatever)

[lime fulcrum]

Hi!
Do you guys know why my Widget Interaction does not interact with the 3D Widget? I see the trace when enabling the Debug, it passes through the 3D Widget and yet it has collision. :\

I'm confused

[wise tide]

Very simple question but if I want something to happen on my gamemode begin play before the parent gamemode begin play I assume I put it in between here.

If I want something to happen after the parents begin play, do I need to add it to the parent BP or can I just drag from the last exec pin?

[lime fulcrum]

no, you add it afterwards

[wise tide]

Like if I drag from that last exec pin will it run that section of nodes after, during or before the parents begin play

[lime fulcrum]

Parent: BeginPlay is used to do stuff from your parent class like things you need to do for all sub classes

otherwise if you don't spaw nthat node it's like you wanna override all of that

it will run after

[wise tide]

I see, so stuff I want to run after the parents begin play, but only on this specific child, I just put after the parent begin play node

[lime fulcrum]

yes

🙂

[brazen leaf]

This is weird. I have an Actor Component class with these two variables set. I made a child blueprint and the child can only see the 2nd variable and define it, not the 1st. They have the exact same settings in the parent (instance editable, public)

I found one weird thing. under Variable Details, Advanced, there's CFF_DisableEditOnTemplate for the one the child can't see. I dont see where that came from or how to change it

Yes, I am able to do that

Right

I need to set it to Actor Class Reference

[solid zenith]

What would I need to use to make a float which would increase in my case from 0 to 1 +0.01 every frame or whatever but could be stopped before reaching 1 too and then come down to 0 -0.01 every frame

[brazen leaf]

I learned this last week but it didnt stick. Thanks @toxic jay !

[faint pasture]

Do you guys use data tables, data assets, data only bps, or some mix?

[earnest tangle]

I'm using increasing amounts of data assets lately as they are quite convenient for storing all kinds of data and configs, and they are resistant to having to recreate blueprints when they get corrupted :P

[faint pasture]

How do you discover them at game time?

[earnest tangle]

they can also be sometimes useful as they support polymorphism

[faint pasture]

Like how would I "get all possible items"?

[earnest tangle]

I just assign them into blueprints and the bp uses it as its settings source or such

I have a data asset which is an array of other data assets for that purpose in my other project

which is then assigned into some BPs that need a list of things

[faint pasture]

Ok so I could make a bunch of item definition data assets and then create an ItemDBDataAsset which contains references to the items?

[earnest tangle]

for example yeah

[faint pasture]

The ItemDBDataAsset would replace the DataTable sorta then

[earnest tangle]

you can also discover them through asset manager but it can be kinda fiddly sometimes so really depends on how you want it to work I guess

you certainly could use a data table too if that makes sense in your usecase, for example if you use spreadsheets for some usage

[faint pasture]

This is for defining hundreds of items, data assets would probably work.

[dense thicket]

to make a MP game for steam, do i NEED a lobby or is it just "nice to have" ?

[sudden zephyr]

The fact that that's a question nowadays is just fu imo but then again, I'm a boomer. xDDDD

[faint pasture]

Depends on if a lobby makes sense for the game

[sudden zephyr]

I mean... Games coming out without scoreboard now too so... xDDDDDD
🤔

[faint pasture]

Our game doesn't have a lobby but it's not a match-based game.

[dense thicket]

thanks, so i guess it does not need it 🙂

[faint pasture]

Can't see shit

[naive stag]

How can I do it so that In arrays, the first existing value will be picked up?

[faint pasture]

How do you have a non-existing value in an array?

array of what?

[naive stag]

References to blueprint

Actor Blueprint

[faint pasture]

Either do a foreach loop, saving the first valid ref to a function variable and returning it when done, or a while loop, bailing out at first valid ref or end of array. Depends on how huge the array is which is better, but I'd lean towards the foreach

Foreach Entry in Array
if Entry is valid and FirstValidRef isn't, set FirstValidRef = Entry
loop end
Return FirstValidRef

OR

ReverseForEachLoop
if Entry is valid, set FirstValidRef = Entry
loop end
Return FirstValidRef

both approaches will return the first valid ref, or a null pointer / invalid ref if none exists

Make it a translucent/masked material. Also, #graphics

[undone surge]

ok thanks n srry ill put it there next time

[naive stag]

Im having a hard time understanding that. Is there a way maybe you can send an image of it or something?

[faint pasture]

Start by making a function that returns an actor reference. Give the function a local variable FirstValidRef

[naive stag]

I did it already

[faint pasture]

K do you wanna do the foreachloop method or the reverse one?

[naive stag]

For each

If it doesn’t work

I would have to go with reverse

[faint pasture]

K so set that up and show what you got
Foreach -> branch -> set FirstValidRef

[gentle urchin]

||||

Oh sry, didnt realize you were doing tut content 😄

[faint pasture]

No, return after the loop is done. But that actually would work I think, bailing out of the for each loop early.

[gentle urchin]

Yeah, this works

[naive stag]

How is it gonna save the first variable?

[gentle urchin]

no reason to iterate further

[faint pasture]

Make sure you have another return after completed returning a null ref

[faint pasture]

or it'll shit its pants if the array contains no valid refs

yup

[gentle urchin]

Doesnt it return the default value if nothing else is returned? aka none?

but its good practice to do so, for sure.

[naive stag]

I have 5 objects that are valid as well

[faint pasture]

Not sure, I havn't pushed the limits of BP functions to see if they break

[naive stag]

I need to pick the first valid object out of those 5

[gentle urchin]

if you wanted to know the index,

[faint pasture]

Is this seperate from the array?

[gentle urchin]

and toss yourself an out aswell

[sudden zephyr]

Why not use for each with break? He's only pulling 1 ref. o.O

[faint pasture]

Function bails out anyway

so it breaks anyway

[gentle urchin]

this is functionally the same

with less wires

less clutter 🙂

[faint pasture]

If they're NOT in an array, make an array out of them and call the same function. Voila, you're reusing code. That's great.

[gentle urchin]

If you're not familiar with the method, i can see it coming off as confusing tho

It's 100% safe to use 🙂

[sudden zephyr]

Wait... Heh... The way the above function is set is that it's gonna itterate and push everything thorugh. So basically you call the function once but it's gonna push each loop iteration. No?
