blueprint

[echo storm]

Or well, the parent class

[lunar sleet]

Well, no, not if it’s a diff PC each time

[flat summit]

Clueless

pcg its to hard for me

brain goes bomba

[heady crypt]

those videos should help you get it done in 25m

[echo storm]

And no I don't think so

[heady crypt]

what you need from PCG anyway

[flat summit]

the thing is that the videos that you sent make everything for a static map, and mine is a infinite spawning map so there is no way to make the pcg thing fit my idea

[heady crypt]

yea, make an actor

[flat summit]

maybe you know how but i dont lol

[heady crypt]

give it PCG

spawn actor

profit

you already have the actor

are you not spawning this actor infinitely for your Runner ?

[flat summit]

actor = coins right?

[heady crypt]

AActor = something that you place in the world

[flat summit]

yea but if i make it so the actor spaws on the ground thats the same, no?

[lunar sleet]

Or spawn

[flat summit]

i mean i dont want to dout you, im just asking

[heady crypt]

your ground is an actor though

make a spline, make a PCG Graph, tell it what to spawn, and you're done

then on construction, make a random float, that's your seed, and tell your PCG what it is

and you have RNG positions

[flat summit]

so, here i click add to create a spline

[echo storm]

If I do auto-possessing it works, but I wonder why the possess node doesn't seem to do anything

[heady crypt]

anything with that logo is of Blueprint type actor

[lunar sleet]

Disable auto-possess and do a get controller with print string on tick (just in case it’s not ready on begin play), see if that shows it’s being controlled already

[heady crypt]

yep, add spline, change it to fit what you want in the viewport, make it a closed loop, watch those videos how to make the PCG Graph, add it to your object, and you're done

then you're almost done on his video tutorial, and you can move onto things like score tracking, map spawning and camera movement

[flat summit]

whatever he does here should i do it on my viewport from my floortile? https://youtu.be/tJkbezOmAwA?t=131

[heady crypt]

yep

just don't drag the spline and graph into your map

add them to the segment

[flat summit]

so, instead of creating a new blueprint i just use the one that i made for the floor right?

[heady crypt]

yea

[echo storm]

Yes, it is printing

[lilac storm]

Is it possible to attach one actor component to anothe ? I got 2 ACs one is for all player abilites second one AC from marketplace which has flying ability staff , i don't want to attach 2 AC to my player , i want all ability related stafff in one place , what is the solution?

[lunar sleet]

What is showing ?

[flat summit]

i cant make the space where the coins should spawn bigger, its just like a stick instead of a circle, even tho i changed the size

[echo storm]

Just the "Hello" string on tick, or was that not how you meant it?

I put the print string on tick in the controller BP

[lunar sleet]

No lol, get controller and plug it in

[spark steppe]

no

[echo storm]

Ahh

My bad

[lunar sleet]

Do it on the event tick of the actor you’re spawning.

[echo storm]

It is showing my custom controller

[heady crypt]

click on the spline, and on the point selection tool, and you can click though the spline points and move them, alt+drag to make a new point, click closed loop to make an "area"

[lunar sleet]

This is with auto-possess turned off?

[echo storm]

Yes

[lunar sleet]

So, it’s working?

[echo storm]

The camera is also positioned properly, just the controls don't work

No it doesn't work

[lunar sleet]

Long shot but try using enable input

[echo storm]

On the character?

Doesn't work either

[lunar sleet]

🤔 Possess is tricky, I rmbr having a similar issue but it was an AI and I think I ended up just using a spawn AI node

[flat summit]

seems like the max amount of points i can have is 2, bc im clicking this icon and nothing is happening

[lunar sleet]

Disconnect your possess node and test it again with the print

[flat summit]

and the thing is the same

[echo storm]

Print what exactly?

[lunar sleet]

lol, the same thing as before, get controller and print its output

Point is to check if it’s already possessed

[heady crypt]

you can have as many points as you like, you just have to make more, you can click on one, in drag mode, hold alt, and drag it to make a new one

[echo storm]

Nope, doesnt print anything

[heady crypt]

tweak the densities

[flat summit]

i was missing half of your blueprint ☠️

[heady crypt]

and then start doing seed stuff

you'll see it all in his video

I'm just showing you how fast it is to make

[flat summit]

i think i know why i cant make it bigger

https://youtu.be/tJkbezOmAwA?t=212 the guy has that massive area, but i cant open that bc im in a blueprint

or can i?

[heady crypt]

you can make the spline as big as you want in your actor

[lunar sleet]

Where are you adding the mapping contexts and all?

[echo storm]

In the parent blueprint class of every character

[lunar sleet]

On begin play?

[echo storm]

That one doesn't work if I use the possess node as well

[echo storm]

Yes

[flat summit]

then its just iq diff lol

[echo storm]

And it works if I use the auto-possess option or set the default pawn in the gamemode settings

Just... the possess node doesn't do anything

[lunar sleet]

Begin play will occur before you possess it, see if you can do it on the PC’s onPossess

I’m checking out a vid about this tho, sec

[echo storm]

I have the controls in the character tho, not in the controller

[lunar sleet]

That’s ok, you just need to add the mapping context

Try this, after possess, get the EIS local subsystem and add mapping the context there @echo storm

[flat summit]

im going to cry

[echo storm]

Wow that works

[lunar sleet]

Yeah, so probably because you were adding it on BeginPlay but at that time it’s not Possessed yet

[lunar sleet]

Yep, that works, or you can also do it right after your spawn -> Possess

But this is prly cleaner

[echo storm]

Alright this is really good to know, thanks a lot for your help

[heady crypt]

^

alt+drag = make more points

[flat summit]

it has to be on?

[heady crypt]

it?

[flat summit]

nevermind

[heady crypt]

and then you can play around with how seeds work, and then refine your graph to more custom way you want it to look

if you want, otherwie don't worry about it

[flat summit]

nah but im going to an mental assylum next week after doing this

in game ofc

[flat summit]

how do i make that red set that you have?

[heady crypt]

the boolean? drag to BP and clik set, or drag to the exec node

2nd is alt+drag

[flat summit]

okay got that one

what about that one, mine has no target

[heady crypt]

yep now make an integer for seed, and make it random, and parse it to your PCG

make it default true for boolean

so everytime it spawns it should change seed

[flat summit]

XD

[heady crypt]

your img too racy

too much seggs

the bool really just there so you can drag the actor in the editor and see how your graph changes are going

[flat summit]

and whats this?

i mean i do right click but there isnt anything called pcg

[heady crypt]

click on add, add a PCG, click on it's graph and set it to your PCG Graph

[flat summit]

add on local variables right?

[heady crypt]

uh no

[flat summit]

where then?

[flat summit]

ah okay

[heady crypt]

and add your graph here

[true oriole]

how do i spawn enemy outside the screen/camera ? i don't want to player to see it when the enemy is being spawned.

[flat summit]

what are you editing there?

[heady crypt]

spawn them in, as default invisible, then check if they are visbile to camera if not make em visible, or make sure they spawn out of range

the PCG

[flat summit]

oh i was clicking this one

[heady crypt]

that's just a ref to the component

[flat summit]

okay

im just missing this

[heady crypt]

get the players forward vector, invert it, set a spawn distance, multiply by that direction, and then pick a random point and spawn them

they'll always spawn behind the camera then

as long as camera is locked to the player

[flat summit]

okay gotcha

everything done here

[heady crypt]

expose them by clicking the eye

closed eye = hidden/private

and set the boolean to default true, so it always changes the seed at least once

later you should make a stream and give it to the player state and then get random seed from stream and set it when you spawn it, but that's a later thing

if you want to keep using the PCG spawn

[languid widget]

alright fuck, has anyone used FVectorSpringInterp before? I can't figure out how the values correlate, my object just flies all over the place

[flat summit]

where is that ☠️ im lost

i know you hate me

[flat summit]

mine has no eye

oh wait

[heady crypt]

yea wides no good, ultra wides needed

[flat summit]

i stil cant find that thing

i have been 11 hours straight doing this omg

[flat summit]

but are we talking about this bp?

[flat summit]

mine is not like that

ah i think i know why

[heady crypt]

lol

you made them local

[cyan bone]

Maybe this is something obvious.
I need to scale the landscape to be bigger. But when i do, the textures all become too big.
Is there something im missing?

[heady crypt]

you can't expose a variable if it's local

[cyan bone]

or this is done in the material, by getting object scale and * multiplying?

[heady crypt]

change your UV Tiling

you're using a material instance right ?

there are videos online about auto scaling textures, I didn't try them though

[feral parrot]

spawning the spheres I need them to block one another when chasing me, how do i do that? in my case I set the collision to block world dynamic and set the type to WolrdDynamic as well but it is not working

[heady crypt]

how are you moving them? MoveTo() ?

MoveToActor() ?

[cyan bone]

i see. so if i make the landscape larger, i need to always adjust the UV scale too in the material

no im not using an instance

[flat summit]

yea bc when i right clicked i didnt have anything called like yours

[cyan bone]

its the main material

[feral parrot]

simply like that so far

[heady crypt]

in the main, make some UVs scalers, make them parameters, then make your landscape material an instance, and you can edit the details without recompiling the material

I can't think of needing to rescale a material after scaling up the landscape though...

[heady crypt]

right, you'll need to do collision volumes and overlaps, and everything, Or just use MoveTo() or MoveToActor()

and it'll path find AND prevent collision with slef and others

you'll need a NavMeshVolume in your scene though

you could give them a capsule component at the ground 0,0,0 and let their mesh be higher and animated so they fly/float, and just tweak your NavAgent bounds like height and radius so they spread out as much/little as you want

[gray cradle]

The cube overshoots for a single frame when setting it to the location of the cell.
Overshoot happens in the direction the cube moves to.
Physics for the cube are disabled and I made sure its location isn't set anywhere else.
Any ideas how to fix it?

[heady crypt]

Is it just a visual issue with Unreal Temporal?
I'd Lerp it from A->B not Snap it to B myself

Are you dragging? clicking?

[gray cradle]

Im dragging the mouse, then the tile fires a "cursor hovered" event and sets the cube to its location.

[heady crypt]

I think it's just a visual thing with Unreal Temporal

like Laura said, turn off motion blur

[gray cradle]

Yes, it was motion blur. Thank you @heady crypt and @toxic jay

[heady crypt]

next you should learn about Lerping 😉

any examples of a game you think snapping would be better than fluid motion ?

RTS placement ?

you don't slide them around without a Lerp though

it's just the spawn point or swapping the mesh from Placement->Normal

yea I guess if they going for a low tech cartoon vibe

[gray cradle]

Actually Ill try a very fast lerp, havent thought of that. Im trying to convert my 2D Godot Protoype to UE - a tower defense game.

[heady crypt]

idk what it is about Unreal but snap movements are very noticable, Camera, objects

you name it

[gray cradle]

Yes, disabling motion blur fixed that. But Im gonna try lerping from a design-perspective. Might give a better feeling when placing buildings.

[heady crypt]

if you want a cool cartoony spawn in feeling, you could create a timeline and make a curve go from 0.8->1.1->1.0 to make it look like it's being enlarged and shrunk

have the update of the timeline set the actor scale

lots of mobile and 2d games have a more exaggerated interaction feel to their stuff

[gray cradle]

Good idea but I was going for an animated spawning

[cyan bone]

it needs. else my grass becomes so big my soldiers look like ants 🐜

[noble quiver]

Hi guys, just wondering if there's a way to display CPU and GPU Time in a widget. It'll be for easy debugging with a build.

[cyan bone]

thanks @heady crypt

[heady crypt]

[heady crypt]

https://www.youtube.com/watch?v=jSlrJDiuiF0

This video was really interesting, if you want to have it dynamic auto scale, instead of manual tweaking

I wouldn't use it for anything other than rocks/landscapes

[heady crypt]

you want a display histogram like POE for computer performance in your UMG Widget?

[cyan bone]

ah object radius * moddifier

[heady crypt]

it's an interesting thing to use for sure, but it's limited to things like rocks and ground that use completely tiled materials

[noble quiver]

Just the frame time would be fine but a histogram would be cool!

[heady crypt]

maybe a spline PCG wall graph

[cyan bone]

i think this also works

[heady crypt]

Laura might know if those variables are accessible, I know that Unreal does track a lot of that for it's own internal details so you can figure what's using how much CPU/GPU/RAM/File Size

[noble quiver]

Yeah I don't nessessarily need a histogram per say so even just raw numbers would be good. I am familiar with the profiler too but my boss wants it displayed in game so if it's possible, many thanks

Willing to use C++ also if that makes things easier

[heady crypt]

I've not looked into if those variables are exposed so I'm not sure

[late dragon]

How do I create an editor extension to generate child blueprints?
is something like that possible?

[supple dome]

explain more

[flat summit]

how is this called or how can i make it

[heady crypt]

Array of Vectors

looks like anyway

[true oriole]

🙏🙏🙏🙏 thx it works!

[dawn gazelle]

That's an Array Add. Drag from your array you're wanting to add to and type in "Add" and you should get the node.

[narrow pendant]

how would I get the name of my level's UWorld?

[lunar sleet]

There seems to be a UWorld::get world function in cpp that might help.

[narrow pendant]

yep I'm in a BP project unfortunately

[lunar sleet]

Then why are you asking about UWorld?

[narrow pendant]

because the world partition commandlet needs the name of the world

that part is not documented though as far as I can tell

[lunar sleet]

Try #packaging , they’re prly familiar with this

[narrow pendant]

will do thx

[proven garnet]

Hello! Practicing BP's and learning by doing basically. I've made a door interactable so I can open and close it. Opening it works fine but closing it doesn't work. I assumed using the return exec in "Move Component To" would return to start position but maybe it's the flip flop that needs to change? Anyone able to give some pointers?

[willow gate]

Hey again smart people. I have an actor with several static mesh components. I set their static meshes from an array of possible meshes and I would like to stack them side by side dynamically. I wondered if there's a way to do this, perhaps using component bounds to find the edge of a box extent and then placing the next mesh next to that box and moving down the chain like that?

[fringe junco]

you need two move component to's one for each angle of the doors position (open and closed)

[dawn gazelle]

If I remember right, Move Component To's return only works if the component is still in motion. You'll need to use some other interpolation system like a timeline.

[fringe junco]

or a timeline

[proven garnet]

Ah okay I've checked timeline a bit but can't really grasp it. I'll try with another move component node, thanks!

[fringe junco]

timelines u just need to double click on them to go into the timeline, and set keys

right click on the graph to set a key

and then u can move the key around to the appropriate place

i have 1 key at 0,0 and another at 2,1

so when its 2 seconds into the timeline, the value = 1

[proven garnet]

I think I've set it up like you have but now it's not even opening

i must be missing something

[thin panther]

show what you've setup

its very easy to miss things when you're staring at it all the time :P

[proven garnet]

So it's not a curve. Maybe I'm missing something here

[thin panther]

it not being a curve doesn't matter. show how you set up the node graph

[thin panther]

thought so

[lofty rapids]

0 to 0

[thin panther]

you haven't set your B rotation

[proven garnet]

Of course!

Haha

We just built a door people!

😄

Thanks for the help 🙂

[frosty berry]

I have an "enemy" that is chasing the player (not using Behaivour Trees). Should the "AI" movement/decision be updated/adjusted every tick, or have its own custom event that has a Delay(.02) then self loops?

[frosty heron]

putting delay on the loop doesn't do anything

Delay happend in one frame

so what happend is after 0.2, you get callbacks every frame from there on

just use Behavior Tree!

[dawn gazelle]

I think they mean Begin Play > "Do Some Stuff" > Delay 0.2 > Go Back to Do Some Stuff

[frosty berry]

Yes, EventA --> do stuff --> delay .02 --> call EventA

[lunar sleet]

Doesn’t really change anything. If you put this on tick, it’ll break

Use the right tool for the right job

[dawn gazelle]

inserts joke about using level blueprint for AI

[late rapids]

Anyone know if there's any difference between these two implementations of interface messages?
They both (appear to) work just fine
https://i.gyazo.com/c1106f4418bc1bad0bea922213f46a46.png

targetting the interface vs targetting the actor / specific object

[frosty berry]

Datura got it right, Begin play calls the event, then it loops itself on a delay.
Have not dug into Behaviour trees enough. (need to)>
Its vehicle navigation based on a target goal....have no clue at this point how to do that in a BT

[lunar sleet]

One calls the function in that bp, one calls the interface

[gentle urchin]

If its a one off thing, bt might not be the tool for the job

Might be better with a temporary car auto-drive component 😄

[lunar sleet]

So, the AI makes one decision and then ciao-s ?

[frosty berry]

Just vehicle chase steering and speed.

[dawn gazelle]

One would require you have a reference to the actor it exists in (The one that says "Target is Player2D Player") the other you can throw whatever reference you have into and it'll attempt to call the interface.

[late rapids]

is there any actual difference between these two? I would have expected calling the interface to do nothing but it does not

[late rapids]

I'm pretty sure that's supposed to be an interface "message" and not whatever this is no?
like if I drag "other actor" without casting it shows something different

https://i.gyazo.com/2eb48367c7c194936dcdb6bcd2f9eee2.png

[frosty berry]

Each "loop" check target location ans adjusts "steering" to stay behind and chase.

[lunar sleet]

The envelope is the message kind, yes

[dawn gazelle]

Yea you're right. I'm not actually 100% sure why the one with the yellow pin exists.

[late rapids]

but between these two, are there any difference?
https://i.gyazo.com/dbd8512fee7f9c7cff7f8f6fa6b2ac17.png

[low venture]

How would you do this with UMG? I want to make something like a "information dialog", like in Windows. "Files have been successfully saved" or something like that. The length of the text can be anything. Now I want the following:

1. the dialog's aspect ratio is e.g. 1:2
2. a dialogs maximum width e.g. 500 is set
3. if the text does not fit into the dialog with aspect ratio 1:2 and width 500, you should be able to scroll it
   I really tried a lot of, but did not get it to work...

[lunar sleet]

Loops and delays won’t jive

[late rapids]

hovering over them shows nothing sadly

well, nothing useful I think

[lunar sleet]

The target basically

[low venture]

The thing with aspect ratio in size boxes seems to be totally broken...

[lunar sleet]

Did you try the appropriately named #umg channel? 😀

[frosty berry]

I call it a "loop" but actually a recursive method/event. Delay is there because I have seen that practice "out there" to do this away from the event tick.

[low venture]

No, but there will be nobody in this channel the most time @lunar sleet :/

UMG is not popular enough

[late rapids]

I mean, is there any difference in changing the target, since I'm assuming we're either targetting the actor, or the interface implemented inside the actor, which should both lead to the same outcome?

[lunar sleet]

Happens when everyone that’s supposed to go there doesn’t, so then no one can help each other because channel is dead

[lunar sleet]

Did you implement it as an event or as a function?

[late rapids]

function

lemmie implement it as an event and see if there's any difference hmm

[lunar sleet]

Yeah, interfaces are a tad weird, when you implement you basically get a call to the interface itself within that actor and a call to the event or function that was implemented as part of the interface

All that being said, I don’t think it makes much difference which one you use, aside from the message/no message version

[late rapids]

ye I understand the message/no message version differences

I guess I'll just use the actor reference until something doesn't work and try interface reference after that

[lunar sleet]

I think I always just used whichever the context showed first

[gentle urchin]

If you need it on tick, use tick

|| ||

[lunar sleet]

Delay on tick? Mad man 😀

[gentle urchin]

Delay on tick gates it, but its not a good use of tick :p

[lunar sleet]

https://tenor.com/view/chaos-gif-26401569

[gentle urchin]

But yeah no reason for the tick in the first place.

Beginplay -> set timer by event -> BrainTick

Increase during chase

Decrease otherwise

[frosty berry]

hmmm.
So far its in tick ( no delay, just running) and no performance issues. But its just me playing in editor right now with only 5-6 "chasers".

Basically, what is the best practice assuming I am not giong to use BT?

[gentle urchin]

Whats it doing on tick if i may ask ?

Like, whats it having to check every single frame?

[frosty berry]

Gets target Location. Calcs distance, steers towards and adjust speed to then stay X amount of distance behind, and a branch in there to see if it should shoot at the target on occasion.

Thats pretty much it for now.

[gentle urchin]

MoveTo does that for you

[frosty berry]

Yeah considered that, but I add in some banking, swerving, etc as its adjusts.

[gentle urchin]

Guess its not the worst use of tick then

[frosty berry]

🙂

[paper gate]

validate check failed everytime ??
even i already add it in viewport

[lunar sleet]

That’s now how you get a widget ref normally. Did you create widget anywhere ?

[versed sun]

Delay untill next Tick after Begin Play

[paper gate]

yes worked thanks

[proven garnet]

Hey! Watching a YT tutorial on timelines and I'm not getting this menu to pop up when right clicking a point on the timeline. I can only double right click but that brings up the "rename" and "delete" menu. Any idea what I'm missing here?

[frosty heron]

On begin play too. I smell a rat race

[low venture]

Even the size box can resize to the border's or text's size (only aspect ratio is set), it doesn't. How to fix that?

Border is horizontally/vertically stretching.

Text too.

[plush ridge]

If I have the rotation value for the red object, how do I mirror it to get the rotation value for the green object, from my POV? If this pattern continues, the colors would flip and when red points down, green points up.

Basically, I already have the red, I want to create the green

[barren dove]

interesting

will that work? it seems like it should require an axis

my assumption was to have a line from the center to the left/right, measure the angle and then multiply by -1 / new angle

[plush ridge]

invert could work but one of the axis should not be inverted (when the line leans towards camera here, both lines should lean towards camera)

[kind estuary]

Whats the difference between using instanced static meshes and foliage in terms of performance?

[plush ridge]

I think you're right, though

it's not just a 180 flip

[barren dove]

okay so
180 degree flip minus the amount from the backplane to the "up" direction?

tough without axis's labeled, lol
I still think measuring it to a known axis (the vertical or the flat plane) then redrawing on the other side makes more sense

there's probably some fancy math way of getting what you want but measure and redraw is for lunkheads like me 🙂

[plush ridge]

some more context: the lines are swords, and it's in 3D ofc

It's in VR, and the idea is that I have a dummy opponent that "mirrors" me. When I point my sword to my top right, he points it to the bottom left (which from his POV is bottom right, hence my image above)

[lunar sleet]

Perhaps you could use DOT product then, tho I guess that takes location vectors

[barren dove]

um, instead of doing lines, if its a skeleton mesh couldn't you just mirror a socket location over the mirror plane and you're done? :x

i have done zero animation stuff fyi

[plush ridge]

it's a static mesh,

I was able to mirror the location/vectors correctly, but the rotations are stumping me

[barren dove]

oh i'd just try to mirror the locations and draw the lines between them rather than come up with that

[plush ridge]

oh interesting 🤔 will explore this

[barren dove]

you know, socket a -> socket B , you have a start and end location, measure and rotate so that the limb does what tis meant to do

[plush ridge]

actually,

it might get weird when the positions swap across the center point, without rotating

the line drawn will produce a new rotation, when it shouldn't

[barren dove]

hm

this shouldn't be this hard

[plush ridge]

I know 😅 couple of us went at it thinking it would be basic but it tripped us up

[barren dove]

okay lets say the plane is the X axis

[versed sun]

the plane is the x axis

[lunar sleet]

The plane is the..

[plush ridge]

the plane is

[lunar sleet]

X axis

[plush ridge]

plane

[lunar sleet]

✈️

[barren dove]

we can get any location to the x axis, and then draw it on the other side , we just can't get the rotation of those locations, so how do we resolve them without involving the original

we know the actor will be facing the player and probably make a few other assumptions

[versed sun]

If you want to Mirror a sword, can you get the Relative rotation, and apply the Invert on the dummy ?

[random pulsar]

Hey,can someone explain how can i do an avoidance 2d system ,like of the player is near enough to a rubbit ,the rubbit runs from player and stops somewhere?

[barren dove]

I was thinking he could break the rotator and pull out the Z so up is up on the other side of the mirror, but thats not going to fly because its not world Z its going to be a combination of things

[barren dove]

can you already move the rabbit around with ai or whatever?

[random pulsar]

No its a flipbook that just stais on place

Stays*

[barren dove]

mmm, okay
so you could try something like add a sphere to the rabbit
OnOverlap -> get all actors that overlap -> you're looking for the player actor
then get the direction and move the rabbit actor

then whenever the player enters the invisible sphere, the rabbit does what you told it to do

[random pulsar]

Ok ,so i paste this collider in actor blueprint ,from the side where i eant the rabbit to run from,or detect the player and then run?

[barren dove]

you're on the right path, its up to you, wherever you put that sphere, is going to trigger when it overlaps the player

[random pulsar]

Thanks

[barren dove]

add an onoverlap event -> get all actors of class and add the player class, then print, so you can see it print when it triggers
once you have that working then mess around and figure out what you want it to do 🙂

[paper gate]

why event tick didnt work in widget when i set visibility of widget to false ??

[barren dove]

there is a setting somewhere that disables widgets when not visible but I dont remember where it is >.<

[random pulsar]

it moves strange,and i know why ,it needs lerp or smth?

[barren dove]

let me see

so what you're doing on overlap, you're getting the actors of class, but not doing anything with any of your outputs, you're just getting the actor and not doing anything with ti

[random pulsar]

adding 5 units to x

[barren dove]

yep yep slow down, let me explain

what you probably want to do is get the location of the player actor, and the location of the rabbit, and then move away from the player, instead of just always moving towards the x, right?

[random pulsar]

yes

[barren dove]

you're probably looking for the "branch" component that lets you set a true/false path for your blueprint

so in this case you can go -> on overlap -> (is the overlapped actor the player?) -> true -> get players pawn location -> get rabbit pawns location -> then things are going to get tricky, you're probably wanting it to move away from the player but stop at the wall, but you're just raw teleporting it right now with set actor location

getting the AI to move stuff for you and obey things like obstructions is something i'm learning right now still unfortunately

[random pulsar]

jesus christ,its hard

[barren dove]

if you're just trying to keep things real real simple, you could do something like another branch to "check overlap" on another actor, like a carrot, then if that is true, the rabbit doesn't run away, if it is false ( no carrot) then you move it

[barren dove]

you can do it, its just thinking of those white lines as a flow and finding the right blueprint objects.
like its doing what you told it to do, on overlap, its moving the rabbit to the right, now you want it to do something more specific so you need to tell it 🙂

[random pulsar]

but for what i need the branch?For example its true,its the player that overlapped ,it will do the true and that's it,if not it will be static as if no branch was in this logic

[loud tree]

anyone know what causes this? Can't seem to figure it out. The buttons all turn into a little white box when hovered like earth is in this SS

[frosty heron]

The image doesn't say much

If your button changed when hovered then open your umg, look at the button brush when hovered

[barren dove]

the problem is here
when the area is overlapped, you move to the right, the "get actors" isn't doing anything at the moment with its output
so if, for example, the rabbit walks over to some other actor, its going to move to the right, if there are two rabbits, they'll run off, lol

so the branch will let you check if one of the "get actors of class" is a player, and if it is, then continue on, if the actor is not a player, then the rabbit wont run away 🙂

since you're making a decision, usually branch is the way to go 🙂

[loud tree]

There is nothing other than the placement and color set up or changed. I've placed them similar to other ui I've made. This has been the first I've seen it.

[barren dove]

so you want to check if the "other actor" on your overlap event is a player , and if it is, continue with your blueprint, if not you can just leave false empty and it'll stop right there

[frosty heron]

Describe your problem again

Your button get hovered and it change to white box?

That it?

[gentle urchin]

Very strange for the GetAllActorsOfClass to be there imo

Seems like a strange strategy

[loud tree]

Yes

[frosty heron]

It's obviously wrong 🙄 he just didn't know what to do I guess

[random pulsar]

oh ,now it makes sence ,thanks

[frosty heron]

Then I reiterate my self for the last time.

Go to the detail panel of your button. Look for hovered selected etc. Change the brush to be the same as the normal brush

@gentle urchin I manage to keep the widget alive during map transition

Using Tsharedptr in gameinstance subsystem

[gentle urchin]

daym

nice job!

but it's static, right?

during load

[frosty heron]

Hmm like the widget?

[gentle urchin]

ye?

[frosty heron]

Can have animation

It's just normal umg

I look at lyra do it if I dechiper it right they also use umg

No idea how they load the level tho

[gentle urchin]

right , i just suspect it to be blocked during level loading

so you couldnt easily play an animation there ? would be my guess

[frosty heron]

I use async load. Animation play smoothly

[loud tree]

I get that. I'll ask elsewhere since I suppose that was "the last time you will reiterate yourself"

I know the normal and hovered are different. I'm confused because I have set up like 12 other buttons the same exact way, not touching the hovered section, they don't do that. I know i can get a work around. I am trying to better my general understanding.

[frosty heron]

Still don't know if I will get lag when loading big lvl but looks Gucci atm

[gentle urchin]

niice, then it'll work yeah

[frosty heron]

Time will tell 🥹

[frosty heron]

Who are they?

[gentle urchin]

I'd suggest making a single wrapped button for your button, to avoid setting up 12 the same way

[barren dove]

yep, you'll get there, 🙂

[loud tree]

Different buttons in different UI.

[frosty heron]

Make a button with common functions that set the style

U can use that button anywhere in different widgets

Oh, I'll have to take a look into that. Thank you.

[gentle steppe]

(I'm not a bot, i just made a reddit post and it got removed so i copy and pasted the posts text, i also just posted onto the ai chat but i think that was the wrong place to say this) I'm trying to make a Zombie AI which is like the World War Z Zombies but a little dumber. I still want them to be fast, climb and sneak up on the players but I dont want ones where you literally cannot survive them. I have looked everywhere for tutorials but I can't find any. I have found some where they aren't as smart and can't climb and are just basic zombies but never anything too smart. I tried using behaviour trees and that was good, but I could never get it just right. Also, I need the animations to stop if the player moves away too quickly because what I had before was a zombie still playing a hit animation like 5 seconds after the player has run away. I'm using blueprints btw

[lean widget]

Hey, I am trying to make a tower defense game, but am new to unreal engine. I understand some basics, but have no idea on how to set this project up or where I can learn how to. I am looking to setup a simple wave system of enemies that head down a path to destroy an object. Any help or direction would be much appreciated.

Im not opposed to learning, just not sure where to find any documentation on this setup.

[supple dome]

break it down
-> How to spawn pawns, how to make pawn follow spline, how to trigger damage when touching something

after you get that working, setup your spawns using ie a table, with enemies classes and delay for example

adjust as needed

[lean widget]

Okay, that helps. I will look into each one of those. Thank you.

[keen girder]

epics cropout sample project is using this formula to scale the mouse cursor based on distance... what is this?! why is vector length subtracted by 9000 and divided by 5000? what is this calculation based on?

[jovial magnet]

it doesnt destroy the actor

shouldnt be equipping atm

it does nothing basically

[lunar sleet]

You’re using interfaces

[jovial magnet]

no

[lunar sleet]

Then no need for an interface

Just make an event

And then call it

[jovial magnet]

uh

[lunar sleet]

Add custom event

[jovial magnet]

can i equip weapons from event though

it should be destroying atm but it equips in full version

btw im pretty new

so sorry

[lunar sleet]

I’m confused. If you want to destroy the actor, just do that

[jovial magnet]

mm

full code destroys the actor, adds the weapon to your hand or something along those lines

[lunar sleet]

Instead of an interface call, just drag from the element, cast to BP_Item, destroy actor on success

Ok, well we don’t know what this full code is supposed to be, if it’s an attach actor to actor or what your tutorial says to do

[gentle urchin]

your guess is as good as mine

harcoded values for FOV + distance?

[keen girder]

thhought they havve a great solution to keep a cursor scaled at distance

[sweet silo]

hi there what wold be your favorite way of activating this radio ? and playing sound on it ?

i've set up an interface but the desk is filed with stuff so i'd rather use a line trace

this is for a first person

[gentle urchin]

What does it actually do? constrain movement within some hardocded bounds?

[faint pasture]

both

line trace to detect what to call the interface on

[sweet silo]

ouhhh sweet

hmmmm how would that work

[faint pasture]

if you're after the fallout style approach, you'd line trace on tick, setting CurrentlySelectedActor

then when you press E, call Interact on CurrentlySelectedActor

[sweet silo]

i have this for now

oh ok really nice

[faint pasture]

idk why you called it pickup

[sweet silo]

yeah no idea

it was for picking up stuff as well but that's a mistake

[faint pasture]

Start with this:

E -> line trace -> call Interact on hit thing

[sweet silo]

or is it ? because i want to use E for picking and interacting

[keen girder]

the pawn is represented by a "mouse cursor icon" and it is just following camera movement. this part just scales the cursor based on distance (which is what i am looking for)

[faint pasture]

Interacting with a pickupable IS picking it up

the reciever of the interact call can decide what to do

[gentle urchin]

the part in the snippet only scales movement based on some stuff, not related to cursor scale?

[sweet silo]

i have this for the door

[sweet silo]

oh yeah yo are right my bad

[keen girder]

d'oh

[faint pasture]

Go ahead and rename that to Event Interact, and also add a parameter to it to send over the InteractingCharacter

so the thing getting interacted with knows WHO is doing the interaction

then it's trivial to do pickups etc

[gentle urchin]

opening project..

[keen girder]

no needd

i should read better

you where right. its the constrained space

[lunar sleet]

So like map size?

[gentle urchin]

yeah

[lunar sleet]

Makes sense

[gentle urchin]

this be the scaling

[lunar sleet]

https://tenor.com/view/calculation-math-hangover-allen-zach-galifianakis-gif-6219070

[sweet silo]

i know it's really dirty and not working what am i missing here "if you're after the fallout style approach, you'd line trace on tick, setting CurrentlySelectedActor
then when you press E, call Interact on CurrentlySelectedActor" i tried doing taht

[gentle urchin]

not seeing any scaling at all tbh

[sweet silo]

@faint pasture

[gentle urchin]

what cursor scaling are you refering to exactly ?

[sweet silo]

i can already hear the screams becausee of that get actor of class

[gentle urchin]

the one i found, or something for the cursor widget itself?

Dont do dirty plz

This doesnt logically make sense

[sweet silo]

that's better

[gentle urchin]

Radio should do what radio wants to do, when interacted with

No

infinite loop

HitActor is presumably self

[gentle urchin]

there's a bug when you drag in cropout

circle keeps being offset from , and chasing towards the mouse location

[sweet silo]

yeah but how can i compare the hit actor ?
Like the line going out from the character shows he is looking at the radio

[gentle urchin]

fun times

[gentle urchin]

what are you comparing?

you dont need to compare anything

Locally on the player you might have a hit actor

[sweet silo]

but how do i tell him that i want it to interact only when he is looking precisely at the radio ?

[faint pasture]

no

what happens when there's another player or another ai character

[gentle urchin]

Radio handles the "i'm currently the hovered/looked at target"

Personally I separate the interaction

and the "hover/lookAt"

into 3 different functions

Interact is for a hovered target

[sweet silo]

hmmm ok i see

[keen girder]

what do you mean by that? and man, sorry for taking your time. totaly misread the blueprint function

[gentle urchin]

not ment to you

And no prob

[sweet silo]

yeah right

[sweet silo]

yeah i should do that do

and also i'm trying to get a sound to play when the radio is interacted with of course

but it's doing the sound on every tick because its linked with the event tick on the thrrdperson charcater

but i guess i should go to sleep haha

[noble ledge]

If I have a node with a target pin but 3 targets pointing to it, does that node get ran 3 times? One for each of the plugged in targets?

[lunar sleet]

3 targets ? Like what

You mean input pins ?

[gentle urchin]

if its a pure node, it'll run one time for each -non pure node its connected to

[noble ledge]

this

[tawdry surge]

Each target will run the function once

[red berry]

Quick question, what colors do people choose when picking colors for comment nodes? Mine are all in grey, but I see people organising in various colors like red, green, blue, etc. What would you need to organise a function in multiple colors for? Whats the convention? Do you have multiple colours for a convulted event graph, and just 1 color for a simple function? Do you setup colors for different things, like logic and UI?

[hybrid hare]

hi, i'm generating with BPa text files saved in a local folder on user PC. I'd like to be able to tell (in BP) the system to replace the or update the txt file is version number (done in BP) is different from the current version in the saved file. Would it be possible or only doable with c++ ?

[lunar sleet]

Entirely up to you

There’s no convention for that afaik, unless you work in a team where they’ve established such rules

For example, in one project I have green for movement related stuff, red for attack, orange for selection. But it doesn’t really matter, it’s more of a visual aid for you

[versed sun]

I like having a color for Temporary code/ Junk test code

[broken wadi]

I use yellow for player inputs, teal for client rpc, light blue for server rpc, dark blue for multicast and default white for regular events. I also use red for when something is disabled or put on hold for now but I haven’t quite decided if I want to delete it or not.

You can also drag the color to the top of the comment details panel and it saves it as a color swatch for reuse later with other comments.

[pallid nest]

hi guys, is it ok to ask question regarding issues you facing with your BPs or is it against the terms?

[lofty rapids]

https://dontasktoask.com/

[broken wadi]

Might be against the terms of what? If the company you work for has a policy that prevents you from sharing code in public then that could be a problem…

[pallid nest]

oh many thanks. I meant terms of this dc to make sure I am not breaking any of the rules of this dc!

[broken wadi]

Seems like you haven’t read the server rules. Maybe give them a read?

Not saying you’re doing anything wrong but it’s always a good idea to at the very least read the server rules.

[pallid nest]

i did, but I couldn't find anything about where to post questions (it just says to be patient)

[broken wadi]

Okay and have you checked out what it says about this channel’s description? 😉

[grave apex]

is there a way to use pointers in blueprint?

[lunar sleet]

But also, just ask

[lunar sleet]

Blueprints use pointers already

Anytime you have a ref to something, that’s a pointer

I obviously read it so there is a reason why I asked it, but thanks.

[lunar sleet]

Ok, but what is the question lol, we still don’t know

[broken wadi]

Seems to me like you have a blueprint related question about some issue you’re facing and are asking to ask if #blueprint is the most appropriate channel. I can’t even…

[pallid nest]

lol one min, I need to get the code etc 🤣

[lunar sleet]

Can you maybe elaborate on what you’re going for?

[grave apex]

I mean like this

if I wanted to set CurrentMeshBeingSwapped to point to Hair Mesh's address

so i could effectively change hair mesh at any time via changing CurrentMeshBeingSwapped's value

this is what I mean by that

is that still possible?

[lunar sleet]

you might be looking for set by ref / pass by ref

[grave apex]

oh!

I am currently using a template for my game (https://www.unrealengine.com/marketplace/en-US/product/advanced-platformer) and basically the issue I am having is that my player start is not working as for some reason the player spawns at a different location (and I can't figure it out how to solve it).

I checked and it seems somehow the issue is related with the last node of my a load game BP (setactorlocation ; concretely, the last node at → https://blueprintue.com/blueprint/_5n0swz6/ ) because when I disconnect sectoractorlocation it goes back to the playerstart.

I believe the issue might be related with a cinematic. As that specific node I created is linked to my level BP (https://blueprintue.com/blueprint/u68i73xq/) and the whole load game BP was part of the template I linked above (which it was working fine prior to the animation).

[trim matrix]

How can i create child of a Data Asset blueprint?

[broken wadi]

Okay if i were you I’d setup some breakpoints in the blueprint code so that the game automatically pauses when they’re triggered then you can double check the values of your variables by hovering over them with your mouse to ensure they are what you’d expect them to be. Maybe the checkpoint location isn’t what you think it is for some reason?

[heady crypt]

make a new BP and click it as your option, you can click all classess and search for it by name

[trim matrix]

that doesn't work with data assets

that's for normal blueprints

[heady crypt]

the objects you make Data Tables out of?

[trim matrix]

my question is "How can i create child of a Data Asset blueprint?" There is no data tables?

[dawn gazelle]

Requires creating a data asset definition in C++

If you're hoping to create a child class of a data asset created in blueprints I don't think that's a thing.

[soft plinth]

Hi @lunar sleet .
I'm tring to spawn an actor on random locations on the surface of a Sphere.

[pallid nest]

ok thanks, I will try that. I think so as it actually spawns in a checkpoint and it is odd because it has already some points (so it is actually loading a game but I can't start a new game as it will do some kind of loophole)

[lunar sleet]

I mean is the sphere your landscape or what ?

[lunar sleet]

Try this: https://forums.unrealengine.com/t/get-random-points-on-a-sphere-surface-to-spawn-actor/116781/2

Hi guys! I have a custom movement system for a character and I was wondering if there was a way to change AddForce to reach the maximum linear velocity I wanted faster. Is there a way to clamp linear velocity somehow?

I would use SetPhysicsLinearVelocity but that causes some issues
A) Jumping while moving gets ignored because the linear velocity set is taking priority
B) Acceleration is too instantaneous

[neon gull]

if break happen does the loop go intoo completed?

or does it skip it

[heady crypt]

looks like break == break; and does your first hypothesis

[neon gull]

ty for testing

Direction * distance + location

My question isn't Blueprint specific but I am using Visual Logger within Blueprint...

I can't find in the documentation any reference as to what the red cone that is pointing down is. The one reference suggests it's the 'selected point on the timeline' which doesn't sound right.

I seems like it's the actor's world location which is doing the logging, is that correct? Do we have control over how this draws?

[trim matrix]

is there a way to set the visibility of a 3d widget per player?

[heady crypt]

#multiplayer need to do RPC and Multicast things

[kind apex]

sound mix not doing anything?
I set all gain to 0 to see if it was my hearing lmao.

doesn't effect any audio at all.

[heady crypt]

Haven't used it before, the location you're using it, is that in an active object in the world? did you put a print string to see if it's being called ?

[kind apex]

straight in the level blueprint

[heady crypt]

oh ok, you clicked blueprints and opened level map and added it there ?

[kind apex]

yesm 🙂

[frosty heron]

doesn't matter where you call it altough u shouldnt do anything in the level bp

Set before push

[heady crypt]

Pop and Push look super useful

assuming you know you would of put an audio mix at some time, pop it off

[frosty heron]

.

[kind apex]

ahh i see, i pretty much want it over every single sound in the game \m/

[frosty heron]

have u done the hierachy?

you can just push the master or base class

that will affect all the children

[kind apex]

so ive tried in the level, player & gamemode bp

no results so far

[frosty heron]

Bruv, I just told you where you call it don't matter

just set it up properly

you need to asasign sound class to each of your sound file

[kind apex]

so i need to do that with every single sound file?

[frosty heron]

You need to assign the sound class for each file yes

This is my Voice file, I assign voice sound class to it

And my voice is a child of the master

so anytime I need to change the whole audio in the game, I just change the master

[kind apex]

alright, so what do i do in this sound class?

[frosty heron]

1. Create a Sound mix and Sound Classes (Refer to the 1st picture, that is the sound mix. Assign the Sound class to the Sound Mix)
2. In your Sound Class, ensure to have proper hierachy. (2nd Picture)
3. Set to override modifier then Push to change volume (3rd Picture)

4. Assign sound classes accordingly to each of your sound file

This is my music folder, they all assigned AtherMusic as the group

[kind apex]

Alright perfect, worked that time \m/

thankye

Hi, I am trying to attach this simulated rope to my character's hand. It spawns but it doesn't get attached to the socket I've set to. What is the problem here?
Also when I move the character the rope just stays the way it is in the picture( it is not attached at all)

[narrow pendant]

you probably need to reference your character in the Parent input

[fleet cosmos]

added the parent, still not working

tried this with another blueprint class and spawns and attaches fine

but with BP_Rope it does not work

Here is the BP_Rope blueprint. Rope is an skeletal mesh that is simulating physics.

[trim matrix]

I need to smoothly rotate normal vector A towards normal vec B on Tick in a way that would also support an edge case where B is the negative vec of A.

How could I do that?

I am hoping to recieve an elegant solution.

[heady crypt]

are you trying to SLerp from A to B? Spherical Interpolation ?

or are you trying to normalize A to B ?

[oak fable]

hey there
i need help with figuring out why my character leg Collison activates behind the actual location of the leg as you can see in the video everything is setup correctly

[trim matrix]

slerp

[heady crypt]

This one ?

[trim matrix]

prob, had no idea such function existed

what about the edge case?

[versed sun]

Turn on some Global Time Dilation when you kick to slow down time so you can see
But it kinda looks like the red area is rotated -1 from your character

[heady crypt]

doesn't matter if A is - or B is -

[abstract mango]

I need quite a bit of help here...

[heady crypt]

it's just calculating A to B and you say it's at ALPHA stage

[trim matrix]

but will it SLerp correctly if B is the exact negative of A?

[heady crypt]

you could drive with a timeline, or drive with a timer, or use tick and just increase SlerpAlpa += Delta

[abstract mango]

So basically I'm almost completly new to UE, and I'm trying to replicate a Mod I've made for an old Doom Engine Game, but in 3D so basically a whole lot better than that old stuff

[oak fable]

yeah it kinda looks like it rotates but why is that ?

[abstract mango]

What I currently need help with is setting up the player controller and the first weapon ^^"

[oak fable]

in the last animation it works fine

[versed sun]

is it at your hip ?

[trim matrix]

@heady crypt do u know by any chance?

[heady crypt]

only used SLerp in Unity never tried it in Unreal

[oak fable]

what is at my hip ?

[trim matrix]

it's prob a similar algorithm (if not the same)

[oak fable]

you mean the start point of the leg collision

[versed sun]

yah

[oak fable]

no its at the knee

[heady crypt]

yea, most mathematical things are universal

[versed sun]

you could do something like this

will slow time while P is pressed

[oak fable]

i saw it it falls down behind the player
while the animation keeps going forward

[steady night]

what component is causing Shadows ?

is there a specific component or whats causing shadfows ?

[oak fable]

thanks you man
it was the anim notify i did start the left leg collision on both right and left anim notifies

[red berry]

While debugging with a breakpoint and simulating, is there a way to see the values of the variables? Or do we have to just add print message to see them?

[lunar sleet]

Hover over them

[red berry]

Wow I never knew that, thanks! This whole time I've been making a mess of my blueprints writing lots of debug nodes

[weary flame]

This is probably a silly question but what is the equivalent to get hit result for a widget instead of something in the world outliner?

I don't want to use the OnPressed or OnClicked event inside the widget.

[lunar sleet]

OnHovered

[weary flame]

That is still an event in the widget itself no?

[lunar sleet]

Yes. Why do you want to avoid this

[weary flame]

Interacting between widgets and actors is something core to the project. Lots of state changes based on that. I want to have a clickmanager that centralizes where the click input goes, who does what and what gets turned off.

[gentle urchin]

Doesnt that just cause indirections for widgets?

[lunar sleet]

I mean #umg is the best place for this, but you should prly look at CommonUI for the advanced functionality like input routing, widget stacking, etc

[weary flame]

Will do.

[abstract mango]

Can I get some help with this? ^^"

Additionally to that, my blendspace for the anim seems to work

but ingame it doesn't

in playtest

[lunar sleet]

It means you didn’t set whatever the Character variable is before trying to access it

[lunar sleet]

Try the #animation crew about that stuff

[versed sun]

If you click the Set Speed it should take you to the trouble spot
you have something called Character plugged into the Set Speed node

Idk what went wrong I redid the blueprint and it worked lol

maybe I had the character in set state instead of get state

[zinc cypress]

Hi, I'm new to unreal.
In my game, I have an input system where the player can type in and commit the text. I want the game to be able to check this message for certain type of keywords so it'll do something specific. For example, if the message contains the word "move", it'll move the player. The way I do this is creating a base prompt class (technically empty class with string/function not meant to be in scene) which is inherited based on different functions (prompt-move/prompt-help/etc with different keywords and different actions). I get this error while trying, could someone please help?

[versed sun]

If you click the Process Input it should take you to the trouble spot
you have something called PromptCheck plugged into the Process Input node

[zinc cypress]

Yes I do.
Here's the widget blueprint. I want to call the function in base prompt blueprint

[lunar sleet]

Funny how the simplest possible error is the one that comes up the most 😀

[lunar sleet]

Yeah, so where is PromptCheck being set?

[zinc cypress]

I haven't set it. I just created the variable and set its type to baseprompt. Since it's not in scene how can I do that?

[lunar sleet]

What is it?

[frosty wadi]

So my actors In the outline are unloaded. Fine, so I pin them to load them but then it says unloaded data layer. Is there anyway to find the data layer bc if I open the data layer outline there is nothing there but the items still show in the outline but not physically visible in the viewport

[zinc cypress]

It's supposed to just contain some keywords and a function on what will happen if the message contains that keyword. Here's the blueprint

[cunning vapor]

Heya guys, for my UI ih ave a switcher -- the switcher seems to be giving everything inside it a lower opacity, is this a known thing ? is there a check box im missing? thanks in advance

[lunar sleet]

Then why not make it an event or function in the same bp and call it a day?

[lunar sleet]

Try #umg

[zinc cypress]

Because I kinda want it to be reusable. This is supposed to be a base class different stuffs can inherit from it (with different keywords/functions but the structure should be the same) and I thought doing it in one same bp may be too much but i guess if there's no other way I can try doing that

[sweet silo]

hi how would you make this pendulum thanks ?

like rotate one side at sec one aand rotate reverse after

[lunar sleet]

There is another way, yes. But this looked like barely any logic

If you want to access a different bp you need an actual reference to it

So maybe put that logic somewhere easily accessible like the player controller for example

then get player controller, cast to it and call that function/event or grab whatever variable from it you need

[zinc cypress]

Ah okay thank you so much

[lunar sleet]

Prly a timeline with a lerp

[sweet silo]

ok thanks

but how can i rotate with a timeline wait i'll check

[flint wind]

Hey everyone, I've been wondering all this time if using multiple get nodes is any more expensive at all than using a single get node for several connections, like right (in the image below) being more expensive than left, because I believe I did read somewhere that it's better the less get nodes you use, but I try to think about how the same "code" would be in C++ and I feel like it would result in the very same amount of lines either way, so I thought maybe it doesn't matter but I guess it depends on how Unreal compiles blueprints. Would anyone know about this? I ask because trying to avoid using extra getters can make the blueprint very messy very quickly. Also, in case it's the same, is it also the same with the outputs of calculations and functions? Thanks in advance.

[sweet silo]

hi there where is the best place to set a reference to my character so i don't have to do it everytime i want' to cast it ? thanks

[dark drum]

As far as im aware it doesn't make much of a difference once you cook your game. (I could be wrong though) The only noticeable difference I've found is a slight (and I mean tiny) increase in the size of the blueprint files. Personally, I would say this is worth the trade off for readability.

[gentle urchin]

Micro optimization in a very unoptimized scripting 'language'

[dark drum]

In the place that needs it.

[flint wind]

I know, right? But I can't avoid thinking about this all the time so, if it doesn't really matter, I can at least stop ""worrying""

[sweet silo]

but isn't there a place like a game instance where i could do it once and for all ?

[dawn gazelle]

Your best bet is to create a blueprint function library and make your own custom pure getter function that tries to get Player Character 0 (assuming non-multiplayer) and then casts it for you. No need to worry about references being valid etc, just call the function whenever you want to get the player character. Casting isn't expensive and if you need to have a reference to the character in the blueprint you're using, there's no difference in terms of memory footprint of that class.

[dark drum]

But then you'd need to get your game instance and cast to it to get your character ref. 😉

If you need a character ref frequently in a BP, cast on begin play and store it for that BP.

[sweet silo]

ok thanks a lot i'll inquire into all this i didn't know about this

[gentle urchin]

Save yourself the brainpower 😆

[sweet silo]

ahha true

[gentle urchin]

It doesnt matter at all, leave it with that

[flint wind]

That's what I'll do, thanks to you both! ^^

[dawn gazelle]

1. Less nodes does save you in terms of blueprint file size in the editor (which is mostly a non-factor). Once packaged it likely makes 0 difference.
2. Less nodes can help with editor performance. Less stuff it has to draw on the screen = more performance, though it does take hundreds if not thousands of nodes on a single graph to start causing it slowdown. Again, this only matters at editor time anyway.
3. Organization and readability is much more important. It'd be much harder to follow a single node connection connecting to things all over the blueprint. Within a small space, it can make sense to use one node and connect to multiple things, but the farther and farther away it is from where it's being connected makes it much harder to follow along with.

[flint wind]

Completely agree about the readability part. Thank you so much for such an elaborate answer!

[lunar sleet]

Should also read the pinned pitfalls of blueprint to get an idea of what happens when using pure functions

[mental trellis]

It stands for pure performance !

[random pulsar]

Hi ,can someone explain how can i make an character ai to avoid the character(move in opposite direction when the player is too close)?

in 2d,so it will be easyer,only left and right

[gentle urchin]

Getunitdirection (playerlocation, ai location)

Gets the direction the ai should move in

[gentle urchin]

flip the inputs 🙂

since you wanna move away from the player

not toward it

[random pulsar]

and how can i connect the execution pin?

[echo storm]

what would be the best way to have this collision box only trigger its overlap event if i am walking from the ground up to the step?

As in like, if I am on top of the step and walk back down I don't want the overlap event of the collision box to trigger

I tried to use the vector to figure out the direction the player is walking towards but it seems very inconsistent

[faint pasture]

Why not put the overlap on the top? What's the actual usage here

[echo storm]

It is a step that the player can trip over

If you don't jump on top of it and just walk against it, you trip over it

That's why I want it to be possible only when walking against it while not already on top of it

[faint pasture]

Try use hit and not overlap

Then you can check velocity

[random pulsar]

ok,now something is working but i have no idea what to do next🙃

[eager rune]

Hey, does anyone know if there's a way to use Get Location at Distance Along Spline but with negative values to represent distance from the end of the spline? Or something similar?

[random pulsar]

not to print but to move somehow in opposite direction the ai character

[eager rune]

Currently I just get the start of the spline with anything less than 0

[faint pasture]

Just use math

SplineLength - SomeValue

[eager rune]

Duh of course

Thank you, I'm dumb

[gentle urchin]

😂

[echo storm]

How do I do that?

[faint pasture]

However you want. You can probably just get the velocity of the actor, assuming that the character movement component actually writes to that.

[echo storm]

Yep, this works perfectly, thank you!

[hollow cove]

where would you put stuff to do with widgets, if you need multicasts (for chat). i notice the HUD class is depreciated, should i shove it all in player state?

[frosty heron]

Very old Epic multiplayer video use player controller

but a reputable member in #multiplayer critisize the video a lot for giving plenty of wrong information so I dunnoe

[heady crypt]

HUD... deprec???

[frosty heron]

Anyway you can only send RPC from Actors

[hollow cove]

player controller wont work for me, each person has one copy themselves and one on the server, so multicasts from the server only effect the owner and server

[frosty heron]

There is a way around it if you want to use UObject

but at the end of the day you have to piggyback the Actor Channel

well it's best to ask in #multiplayer

only server can call multicast btw

and server have everyone controller

[hollow cove]

im just curious what people were doing for best practice or commonly for the main place they store widget stuff

[frosty heron]

I can only tell you what Epic does

they used player controller to send Widget Information

including chats

[hollow cove]

i looked back on my notes to make sure im not losing my mind

[frosty heron]

That;s more or less correct imo

I would save the picture from the compedium tho

[hollow cove]

theres no way to send a message from your player controller on the server and have it reach another client

[frosty heron]

There's a way

[hollow cove]

unless i start casting to player state or something else just to do that

[frosty heron]

unreal put their logic in player controller, im 100% sure

it's old video and im not saying it's best practice

all controller exist in the server

so server can do w/e

including iterating everyone player controller and telling them to update their widget

[hollow cove]

hm i guess thats possible

[heady crypt]

Client->Ask Server to send msg
Server->Auth it?->Send to all : scrap it and ban player

[frosty heron]

Player on Machine 1-> Server Rpc (Send Chat Msg) -> Server Iterate through all player controller Multicast (Update Text)

[heady crypt]

bruh, I don't see anything about this HUD deprec, not even on the 5.3.1 documentation

[frosty heron]

me too

You don't send anything from the HUD / Widget anyway in multiplayer context

send info from actors you own

[thin panther]

It isn't deprecated

[heady crypt]

and it's not in the source files...

[frosty heron]

Lyra is quiet interesting

you can't even find player controller there

[heady crypt]

lol really ?

[frosty heron]

Yeah

but I don't bother to take a look

Laura says it's only for AAA practices

[hollow cove]

so this

[frosty heron]

not for solo dev

She advice me to look only for the Loading Screen stuff

[heady crypt]

I was sure the video on Lyra ability ground targeting was doing Player Controller stuff, maybe I was as high as Olie

[frosty heron]

I haven't tap into Multiplayer game yet, but can't u just get all of the player controllers from GameState

[lunar sleet]

#multiplayer is the place to ask, but there is a player state array iirc

[frosty heron]

Nowhere it says deprecated 🤔

[heady crypt]

HUD uses UMG though, so...

[frosty heron]

Oh it does says that

no idea where the info is from tho

[hollow cove]

you can get an array of player states, idk about controllers

[lunar sleet]

HUD is not deprecated

Some random Reddit user saying “I know it’s deprecated” is not a real source

[heady crypt]

they pretty in your face about deprec stuff

[lunar sleet]

You can still use it, it’s prly just less popular now that the engine’s evolved a bit

[lunar sleet]

What does that prove?

[hollow cove]

theyre trying to say they're obvious about stuff like that

[lunar sleet]

Ah ok

[heady crypt]

if HUD was deprec, they'd have many things in engine and source files saying it

[hollow cove]

so i shouldn't trust random redditors, i've been tricked once again

[lunar sleet]

It’d be a sad day when getHUD doesn’t work anymore lol

[thin panther]

It's a very common misconception, one even I believed at some point

But no it isn't deprecated

Still used heavily

[frosty heron]

Anyway you can prob get actual guidance by #multiplayer guys

[hollow cove]

what is the most common place to store the stuff though if you need multicasts

[heady crypt]

[lunar sleet]

#multiplayer

[crude spruce]

Any tops on how to turn these types of traces into something that can get all bones it crossed rather than the first?

im currently excluding first hit actor and take the bone from that hit result

if i dont exlude the actor i get hit results for trace x tracepoints

[lunar sleet]

maybe multiple traces on diff channels?

[crude spruce]

hmm

perhaps

the result i want is some kind of cleave result

but i realise its very different from an initial hit calc

[lunar sleet]

Then maybe get overlapping components on a timer during the animation

[heady crypt]

maybe do it in the inverse? have the HIT/Overlap bones tell the player/sword it hit them ?

[lunar sleet]

That could work too

[crude spruce]

or maybe i can use the full trace cluster during the frame first line hits something

[heady crypt]

and give them a small lock out timer to prevent multi results

[crude spruce]

ill think about this in in a minute

[lunar sleet]

I think someone here was using multi-sphere traces for this

[heady crypt]

the punching and kicking one ?

[lunar sleet]

I can’t attest to the validity

[lunar sleet]

Idk, could’ve been a sword thing

[crude spruce]

im not very keen on using shape traces

[heady crypt]

I know there was a video from 2-3 hours ago of a martials arts punch and kick flip sick tricks with debug sphere overlaps

[crude spruce]

i prefer the details as i build around detailed hits

i guess i could do a custom shape per frame as well but whatever

[keen widget]

is there a way to Get NAME of the Varible?
(for example to compare it to other varible outside structer if they names match)

[lunar sleet]

The same way you would print it

[crude spruce]

since i do the trace line by line in a loop i could have the fully spectrum of hits after one iteration

[keen widget]

i dont undertand, please can you show what are u talking about ?

[crude spruce]

he wants to compare the variable name not the value it contains

[keen widget]

yes! 🥹

[lunar sleet]

Yes and ?

What type of variable is this

[crude spruce]

it feels like an unwanted solution tbh

[lunar sleet]

Hold on

Are we talking in editor variable name?

[crude spruce]

yes

[dawn gazelle]

You totally could in C++ and even expose it to blueprint, but not natively in blueprint.

At least not as far as I know.

[lunar sleet]

I don’t rly see the use case of this but yeah

[keen widget]

problem is this
i need to compare if varible in the struck are the same in the graph and set them

for example player type in the editeble window: "HP 20"
then my logic will see that varible name match his text and set 20 to HP

[dawn gazelle]

Yeah blueprint isn't great for something like this. You'd effectively have to have a branch for each variable name that could be contained in the "Match" field.

Or a switch on string.

[keen widget]

so there is no "get variable name" node ?

[lunar sleet]

There’s get display name but that’s for vars referencing assets

Hence why I mentioned the print

[crude spruce]

so for 1 frame i can detect between the 2 blue points. I could however. Reduce the loops per hit and reset the trace at that point but im not comfortable stacking a result outside an iteration.

or wait are the red squares the start of the trace?

[keen widget]

maybe this can help me? https://github.com/colory-games/UEPlugin-AccessVariableByName

[heady crypt]

they should be the hit point

[dawn gazelle]

Here's the thing, what you would you do aftewards if you could compare them? What would come after that branch?

[heady crypt]

red line to square = empty space, red square green line everything after hit point

[crude spruce]

are you sure? i think they indicate where it starts or ends

[keen widget]

then matched TEXT would be set as variable in the struct

[heady crypt]

so many naked stone boys

[lunar sleet]

Red squares denote Impact Point

[crude spruce]

hmm

something is off with the phys asset

[heady crypt]

they usually large capsules

[lunar sleet]

Collision capsule prly

[dawn gazelle]

What you have here isnt' even a valid comparison though. Like, how would you know what variable to set the value into?

[crude spruce]

im testing against phys assets

[heady crypt]

you can tweak them yourself if you don't mind doing it and adding more computation time on physics results

[crude spruce]

capsule not in play here

[lunar sleet]

Oh, then idk

[heady crypt]

PAs should be a whole heap of capsules

[crude spruce]

it is 🙂

[heady crypt]

hand, forearm/arm head, neck

[keen widget]

yeah maybe you right

[heady crypt]

stomach, spine, chest, pelvis, leg1,leg2,leg3

[crude spruce]

this is my intention and how i have done it. I just have the wrong override. mannequin. instead of one for the actual body mesh.

[lunar sleet]

I’m also concerned about why you’d have the player type random stuff in and try to detect if they’re talking about a specific variable you have in your struct, but that’s more of a design consideration

[heady crypt]

yours musn't be this close to the "skin"

[crude spruce]

i tihnk i just forgot to account for the changes in the model

however the this was more confusion than problem

[heady crypt]

lol

[crude spruce]

my characters are modular and introduced a heap of problems for detailed collision detection

i should probably pause the cleave result so everything is good atm 😄

reversing and reporting from the hit bones/parts is probably a good way to do cleave as well.

[heady crypt]

depends how performant it would be having them handle the hits done, but it would be the most accurate way to report what is hit and when
