Like binding the "End ability" to a spawned actor is a bad practice?

Or is it an Unreal Bug?

[shy matrix]

No its neither

But you need to be aware that normally you can't reactivate an ability that has not ended

So if you delay the end of the ability

You are also delaying how quickly you can activate it again

[raw dragon]

Yes, I know. But even when the ability has ended, the issue remains.

[shy matrix]

Are you sure?

Try ending it right away and see if the issue is still there

[raw dragon]

Yeah.

If you want, we could hop into a channel real quick and I could show you.

[shy matrix]

Eh I'm on my phone and in bed now 😛

[raw dragon]

Ah okay, no problem.

[shy matrix]

But I'm quite sure your problem is there

[raw dragon]

I'm now ending the ability right after spawning the actor.

Oh wait.

[shy matrix]

Yes. Well everything you do after end ability won't be executed but yea this should work

[raw dragon]

One second, I'm testing.

It did not fix the issue, actually.

I still have to press it multiple times.

[shy matrix]

You're judging this based on how many actors you are spawning? Try to add a print string in the ability and see if that is printed consistently

[raw dragon]

I still have to press in rapid succession like here. But when I do, the ability fires off again on every second press in rapid succession.

[shy matrix]

Hmmm

Then im a bit at a loss

[raw dragon]

I also find it very confusing.

I think the issue is the mouse button press that is required.

[faint pasture]

I smell instancing policy

[dawn gazelle]

If the print string on the input is not printing, then something else is consuming input.

[raw dragon]

I just did this on activate ability.

And then it bugged again.

Or well, got inconsistent and required a rapid double press.

[shy matrix]

Yea that was weird indeed but then he confirmed that removing the activate ability the print was consistent

It still shouldnt be tho

Like it should not change a thing

[dawn gazelle]

Can you show how you are granting the ability and if you have any other bindings for input within the ability?

[raw dragon]

Yes, one sec.

This is in the player character.

This is a component attached to the player character.

[dawn gazelle]

<_<

Yea sorry, I just realized what I was seeing XD

[raw dragon]

All good.

Basically the ability is stored in a variable.

And this variable is set through the interface via the component.

[dawn gazelle]

Are you using anything like what GASDocumentation shows for input binding using enums?

[raw dragon]

I don't think so? How does that work?

[shy matrix]

It's a bit convoluted. But still i can't see how this could cause the issue

[dawn gazelle]

What happens if you change the input to a keypress instead of the mouse?

[raw dragon]

The thing is that I have the same set-up for Q E and R buttons and I don't have the issue there.

[shy matrix]

In general it sounds like your ability is swallowing input somehow

[raw dragon]

They work just fine.

[raw dragon]

I do that with other abilities. And they work without issues.

[dawn gazelle]

But what about this one specifically.

[raw dragon]

I'll test.

With another IA it works.

[shy matrix]

One thing you could do is start with a bare bone scenario where you have a clean, new ability assigned to that same input with a print string in it and nothing else. And confirm that this works. Then gradually port more functionality until you can isolate the issue

[dawn gazelle]

What about the same IA, but the IA itself is bound to a key input and not the mouse?

[raw dragon]

I'll try it, one moment.

Changing it to a different button on the keyboard also resolves this issue.

I set it to T for testing.

[raw dragon]

I did that by ending the ability as soon as I activated it without any other logic. The issue remained.

I think the problem is an interaction between Input Actions and Mouse Buttons?

[dawn gazelle]

Oof... This seems like its becoming a mouse hardware problem.... Are you able to test your clicking on some external application? Like https://www.clickspeedtester.com/kohi-click-test/

OR even setting that IA to use RMB instead?

[raw dragon]

My clicking is working normally.

RMB has the same issue as LMB.

[dawn gazelle]

How about using "Started" insted of "Triggered" on the IA event?

[raw dragon]

I've tried that too, has the same issue.

[shy matrix]

If this is true, the ability is doing something fishy

[raw dragon]

I don't think so. The ability is consistent as soon as I changed the binding from a mouse button to a keyboard press.

This is the only thing that has consistently worked so far.

Anyways, thank you guys for all your help so far!

[dawn gazelle]

Can you show what your details panel looks like in the ability?

[dawn gazelle]

This could be interfering

[raw dragon]

But how?

It's like that for every other ability too, and they all work fine.

[raw dragon]

Btw just for testing purposes, I used a different mouse and had the same issue occur.

I'll try to figure out a solution tomorrow or saturday and if I find something, or figure out what causes the issue, I can give y'all an update.

Thank you two for all your input, it helped alot!

[inland walrus]

Anyone know why the villager doesn't move to the 3D widget?

[faint pasture]

show your code

for how they know to go there

[inland walrus]

That's my bad, I thought I put it in the video

[inland walrus]

Sorry

[faint pasture]

Draw a debug sphere for a few seconds at that location when the order is given

[inland walrus]

like this?

[proven loom]

what's this mean?

"The window is ticking."?

[faint pasture]

Sure, give it a duration tho

just to make sure the spot you're telling it to move to makes sense at the exact time you're telling them to move there

[zealous moth]

From a conceptual standpoint, I have 2 dancing animations for the male and female dancers. However the meshes are not to size, meaning one is shorter than the reference animation. When retargeting, they are off.
What would be a better idea? Adding 2 bone ik and trying to fix the positioning or just use sequencer and either correct and redo it all?
I haven't used sequencer extensively but using blueprint to constantly correct animations has become tedious.

[wet nymph]

Your walking speed is not sync with animations

[frail pilot]

How would I make it so the camera will move in or move out based on the distance between the two fighters?

Right now it justs follows them currently and stays between them

[dawn gazelle]

Maybe if you had a spring arm attached to the camera and adjust its length based on the distance between the two fighters

[frail pilot]

Ah, I never thought of using a spring arm

[faint pasture]

Depends on your desired rule but a distance of 1.5x the distance between the fighters is a good start

[frail pilot]

Alright

I added a spring arm so now I'll figure out how to make use of it

[frail pilot]

Would I change the actual Y position of the spring arm?

When I try changing the target arm length value itself while playing, it just kinda skips to the left and is off from where the desired default location should be

[zealous moth]

use trig

using an equilateral triangle as a base or 2 right sided triangle, adjust the camera angle based on the distance + offset of your fighters

@frail pilot

[faint pasture]

no need

if you want a constant position on screen of the characters then just use a constant distance multiplier

[zealous moth]

well he needs to change the field of view angle no?

[frail pilot]

I don't think changing the FOV is necessary?

Because in the UFC/Fight Night titles, it seems like the camera just moves closer or farther depending on where the two fighters are

And I'm trying to achieve that effect for my mma project

[faint pasture]

camera offset being a multiple of distance between fighters will keep the angle between fighters constant

[frail pilot]

Alright

So would I or would I not use boom arm on camera still?

Because imo, the boom arm is really weird

[faint pasture]

You could but I only would for the smoothing purposes here

[frail pilot]

I'm not worried about smoothing tbh

[faint pasture]

ok then don't

[frail pilot]

Alright

[tough badge]

Is there a way of getting all of the options of an Enum in a blueprint? I'm a bit of a smoothie and can't figure out how

[dawn gazelle]

What is it you're trying to do with them all?

[tough badge]

I'm trying to fill out a right click context menu with buttons like in Runescape. When the player right clicks I get an interface that checks how many states an actor has and fills out the right click menu with whichever states the actor currently allows (like right click > open chest/close chest/search chest/blow up chest/etc).

I was thinking I could use an enum to list all the states and pass those off as a string or somethign to the button widget but I can't figure it out

[dawn gazelle]

There's a foreach for enums. There should be one for any custom one you made as well.

[tough badge]

Yea I tried that, but it returns 0 every time I run it

or at least as empty

Or is For Each loop different

[dawn gazelle]

For Each Loop is different

[tough badge]

That's exactly what I'm looking for lmao thank you!!

It feels like it's always something easy that I'm over complicating or missing lol

[gentle urchin]

this new ? 😮

cant recall seeing that

[cyan musk]

Hello, I'm trying to make player character look at his target every time he attacks. My Look At Target function is working if I call it in event tick but not when I call it in attack event. Does anybody know what why and how to fix it?

[gentle urchin]

RInterp requires tick

[fiery swallow]

this was like before 4.26 , dunnow hen it was released

[gentle urchin]

If you dont want the tick, you'd need to set the final rotation directly

[fiery swallow]

but ye it's oooold

[gentle urchin]

guess that just means im older , rip

[fiery swallow]

haha you're old 🫵

[cyan musk]

Thanks 😆

[dawn gazelle]

Been around for quite some time

[gentle urchin]

damn. guess i've just never had the need for it then

[lunar sleet]

Same but good to know it’s there

[cosmic wadi]

So say I wanted to create a ring that's safe on the inside and outside but damages the player if they touch it. How would you go about making a ring shaped collision? Or would you just build it out of smaller primitive shapes?

[frail pilot]

Still haven't figured this out and idk why

Ik it's not that hard but I just can't think of how to do it

I've tried ways but it's not happening

Idk maybe I'm just overthinking it due to this being my first day of UE4

[faint pasture]

distance

if overlapping and > innerradius

or 2 overlapping spheres

if overlapping 1 but not the inner

[heady reef]

I'm not sure where else to put this question: I'm working with an Xbox Series gamepad and have noticed that while play testing, in the background it appears to interact with the Unreal Editor, closing tabs, which I then have to re-open manually. any way to prevent interaction with the Editor?

[gentle urchin]

launch in standalone ?

[heady reef]

that's how I playtest, yes

[gentle urchin]

cant recall seeing anything like that tbh

[gentle urchin]

in viewport seem to work fine

gonna test standalone in a sec

[heady reef]

hmm, the gamepad just appears to be interacting with the Windows API. just now, while playing it switched the active tab from the StandAlone Viewport to VisualStudio

[gentle urchin]

using some plugin or something?

[heady reef]

no

[gentle urchin]

RawInput or whatever it's called ? ok

[heady reef]

and there appears to be no interaction when there's no game instance active

it most commonly happens when I use the facebuttons (in my case the X, which in a way sounds plausible for closing tabs?)

[chilly sundial]

When doing a line trace for objects, I only want it to detect the door component, but not the collision boxes (they are only used to detect if the player is inside or outside).
I'm failing to set up collision response properly. Is this possible?
Or do I have to check the hit result and ignore it if it is a Box or sth like that?

[dawn gazelle]

You'd need to change the "Object" collision responses on the colliders themselves to not respond to the type of object trace you're hoping to use.

[cosmic wadi]

Thank you! I honestly hadn't considered that yet

[fiery swallow]

Distance. Find the center of both fighters, get the distance between the two fighters, the further the fighters are away from eachother, the further the camera should be "zoom out"

as the fighters got closer, the camera would essentially "zoom in"

there's a node to get the center of an array of locations but I don't remember the name

there's multiple ways to get the center of two vectors though

https://i.gyazo.com/0c68e36ccad5f3043906828cd4c985a5.png

nvm found it

https://i.gyazo.com/0fa9a0707f1e283a37681d6ab045c31d.png

I believe this will also get you the center if it's just two actors

[dark drum]

I would have the camera on a spring arm. That way you would move the spring arm location so it's in the center of the two targets but you can then adjust the spring arm length as well.

[prisma tree]

I have this really weird issue where suddenly a variable wouldnt save/load properly. After hours of debugging it seems that variable stopped working. I created a new one just like the old one and it works! I hate stuff like this....how can i know when it will happen again?
This is the savegame actor:

The test bool is the new one that works and the desrtintrotext is old one and doesnt save

The variables are identical in my savegame blueprint:

[manic vessel]

What is the best way to have a base actor that can be either a skeletal or static mesh. Currently I have one for each and thought I would try to combine it on to a single base actor, It works But I noticed the root is not the mesh 😦 and any other additions in the child actors wont be attached to it.

[crisp sandal]

how can i make sure my player doesn t fall threw the map when respawning

fixed it dunno if this is the correvt way tho

[gentle urchin]

Setroot?

Cant you do that dynamically?

[manic vessel]

Nope cant be done in BP. I talked it out with GPT and decided to abandon this method.

[gentle urchin]

Bypass it and spawn replacement actors of the same class 😆

[crisp sandal]

how can i set the die location but at the same time reload the world ? so the dead enemies come back

[little moat]

Can someone help me with doing a line trace?

[gentle urchin]

you can specifcy component attachment tho

[little moat]

I'm trying to do a line trace with a 3rd person character and from my AI so I can't use the camera

And honestly I'm clueless how to do a line trace in the right place

Like in front of the character

[gentle urchin]

GetActorLocation + GetActorForwardVector

[little moat]

Tried

[gentle urchin]

it is correct

so

just make sure you dont let it detect yourself

[gentle urchin]

multiply by float

not by vector

[little moat]

Oh.

[gentle urchin]

you want to multiply the entire direction with a length unit

[little moat]

So I just split it?

[gentle urchin]

no

right click, and swap the pin for "float (single/double precision)"

[little moat]

Like this?

[gentle urchin]

yepp

perfect

distance > 0 😄

[little moat]

But wouldn't it now multiply xyz

[gentle urchin]

yes

that's what you want when you have a direction vector

[little moat]

What the fuck

💀

[gentle urchin]

you're going from mesh,

which is mesh pivot

[little moat]

Yes

[gentle urchin]

dont go from mesh

go from actor

[little moat]

What should I go from? I don't have a camera

[little moat]

oh.

So this?

[gentle urchin]

yepp

dont really need to cast to NPC BP but whatever

[little moat]

Yeahhhh

[little moat]

Oh yeah true

[gentle urchin]

you forgot the start 🙂

start is actor location

[little moat]

Shit

Sorry I'm a bit tired

A bit

[gentle urchin]

now the question is why your mesh forward is high up like that

makes no sense

[little moat]

Fortunately nicotine exists

[gentle urchin]

it can be fixed tho

Normalize2D

[little moat]

Yup

[gentle urchin]

before multiplying

[little moat]

Like this?

[gentle urchin]

yeh

this ignores Z

so it should now go straight

[little moat]

Well it didn't really change anything...

[gentle urchin]

that cant be right

print the start and end vector

[maiden wadi]

Multiply 500

[little moat]

StartTrace, StartTrace + Camera->GetForwardVector() * 500.f

    const FVector StartTrace = Camera->GetComponentLocation();```

[gentle urchin]

LOL

[little moat]

This is what I use for my cpp

[gentle urchin]

• !=

should be multiply yes

xD

[little moat]

Wait what

[gentle urchin]

yees

[little moat]

Oh it's a +

Not an x

[gentle urchin]

multiply the direction with a distance

[little moat]

FINALLY

[gentle urchin]

you're eyes are sharper than mine

didnt even consider it being a + xD

[little moat]

Now it works

[maiden wadi]

😄 Been staring at a lot of vector code lately. Been messing with geometry script stuff.

[little moat]

Yeahh neither did I

[little moat]

Thanks a lot tho

Now I just have a question

Is tracing a valid option for npcs detecting obstacles? Or is there some other system?

I wanna detect moving things so line trace works but I thought AI could have some built in mechanic for it

[maiden wadi]

Obstacles for what?

[little moat]

I mean like if my npc is walking and then another character goes in front of it

I want the npc to stop

[maiden wadi]

Unsure on the stopping part. Most times to have AI avoid each other you'll use the detour crowd control and they'll just steer around each other.

[little moat]

Is that a plugin or some built in thing?

[shy matrix]

There is no inbuilt tool for this afaik . But a trace should work

[little moat]

I mean yeah avoiding would be smarter tbh

But this is a prototype

I'm tired of being a perfectionist

Still I wonder if line trace is a viable option

[maiden wadi]

I haven't used it much but it's engine default. If memory serves it's mostly making their ai controller a detour controller maybe. There are a bunch of guides on it though, it's pretty common.

[little moat]

Why is the line trace there tho

[shy matrix]

Detour is for avoidance. And you need a lot of manual tweaking to get it to work right. If you want to stop and repath a trace is good enough in my experience

You can try asking in #gameplay-ai though

[little moat]

So it should be a viable option too?

[shy matrix]

If you want your agents to avoid each other while continuing their original path yes

If you want them to stop when they face an obstacle then not

[maiden wadi]

I know that it is for avoidance. I literally said that.
Unsure on the stopping part. Most times to have AI avoid each other you'll use the detour crowd control and they'll just steer around each other.

[little moat]

I ment that is tracing a good option for that

[shy matrix]

Sorry man I missed it

[maiden wadi]

If you want them to just stop moving if something is in front of them traces are fine. But it's a complex issue. What happens when two things walk in front of each other at the same time, facing each other? Which one moves out of the way to avoid a standstill? You also add on code to maintain a state machine of stopping and moving.

With avoidance you simply set it up, and let them go

If you would like avoidance more, it's less work. If you want the stopping, there are a lot of issues to solve.

[little moat]

Oh yeah true

I could stop the movement then add a delay and re enable it again and choose a different path

Like in GTA V

Npcs usually stop for a while then they change path

Or run you over...

[last jacinth]

if i move too far from where the player starts i get this error... anyone can help with this?

[shy matrix]

share ze code

[little moat]

Can someone help me understand why is this not working?

I want the npc to move to a new location if it hits something and then continue moving to it's original destination

[last jacinth]

so, i'm using Openland for landscape deformation this is where the code seems to break

[shy matrix]

where are you calling this function?

[last jacinth]

here, its used to move a render target

it runs just fine, but when i get too far from the start location it breaks, if i go back it runs again, its confusing :/

[shy matrix]

i dont understand your setup. where is this function running? on the player? on another actor? need context

is it called on tick? on a specific event?

[last jacinth]

its called on tick, i didnt make this, i just took it from the Openland plugin, its open source, this is the link for the plugin
https://github.com/GDi4K/unreal-openland
i'm using it to make footprints in the desert and i honestly don't know how it works exactly but it uses a render target and it moves it with the player i think

and this is the effect i get from it

[chilly sundial]

For some reason, this doesn't work. I set WorldStatic, WorldDynamic and Pawn to Ignore, but it still responds...
Also, this breaks the component begin overlap, which I need.
So I'd like to detect an overlap of my character, but it should not respond to a line trace from the character. Is that even possible?

[shy matrix]

the only thing that comes to mind is something related to world partition and getting to a point where somehow the cameramanager is despawned (even if i dont even know if that is possible). Are you using world parition?

[last jacinth]

i think so, since i'm starting with the open world map just changed the landscape isn't by default enabled? but if the camera manager is despawned why i still play normally? it just stops making footprints

but the map isn't large its only 2km

[shy matrix]

as said, to me is quite weird that camera manager despawns because it should be always relevant. but, you could try increasing the loading range and see if that makes a difference

also check that the camera manager moves with your player while playing

[last jacinth]

how can i check if it moves with the player?

[shy matrix]

if for some reason it is detached from the player and stays in one place, then perhaps it is picked up by WP and destroyed

[last jacinth]

i was watching the coordinates for the camera manager and they change while i move, so it is moving

[shy matrix]

play the game in editor, move around a bit, shift+F1 to get mouse control and check in the outliner that the position of player and camera manager are the same

[shy matrix]

ah ok good

then i dont know 🙃

[last jacinth]

do you think Hlods have anything to do with this maybe?

[shy matrix]

i highly doubt it

but it does sound like a WP-related issue

[last jacinth]

the numbers don't seem to match, did we find the culprit?

[frosty heron]

Why would they match? Also controller doesn't really exist physically. Sure you can specify location on controller, but they kinda meaningless

[last jacinth]

WP = world position?

[frosty heron]

if you want to check the position of your player then get the player's physical representation. Normally a pawn.

[shy matrix]

partition 🙂

[frosty heron]

WP for world partition maybe

[last jacinth]

now how can i disable it, and check if this is the cause?

[shy matrix]

i think it would be easier to just increas the loading range a lot if it is just to debug

hold on

world setting tab (Window->WorldSetting if its not visible already)

[last jacinth]

okay its working!!

[shy matrix]

now you can see i didnt activate windows....

[last jacinth]

i increased the loading range to cover the whole landscape and it works

[shy matrix]

😛

yet

[shy matrix]

yep good, then the camera manager can be despawned by world partition

somehow you got a big offset between player position and the camera

[last jacinth]

won't this hit performance hard after i populate the world though?

[shy matrix]

yes yes dont leave it like that

you need to fix the offset of your cameramanager

[last jacinth]

lol i don't know how to do that

[shy matrix]

well something is causing it. try to look into your character setup, other possible bps or code in general that is setting camera position

you gotta dig in

[last jacinth]

aside from all this, what other alternatives should i look for, to make footprints?

@shy matrix also thank you very much for the help

[shy matrix]

wouldnt know. I remember a plugin from prismatica that mmmaybe could do for you but honestly not my cup of tea

[shy matrix]

no worries!

[last jacinth]

i'll check that out thanks!

[last jacinth]

actually, its not the camera manager that gets despawned, its the blueprint that moves everything together, so i just need to figure out a way to make it follow the player 🙂

[shy matrix]

ha, it sounded weird that the camera manager would be setup to be spatially loaded by default indeed

[last jacinth]

is there anyway i can check an actor to be persistent no matter what?

[shy matrix]

IsSpatiallyLoaded on the actor in the Streaming category

uncheck that

[last jacinth]

that did not fix it unfortunately

[shy matrix]

you mean the bp is still loaded but the issue persists?

aaanyway, id focus more on that offset between camera and player

it cant be good, unless you mean to have it

[last jacinth]

its the default unreal 3rd person blueprint i doubt its a mistake

[little moat]

Can someone help me understand why ai move to isn't working?

This runs on tick btw

[crisp sandal]

why won t you make a behaviour tree?

[little moat]

Can behavior tree avoid dynamic obstacles?

And also this is a task on my behavior tree

[crisp sandal]

yeah

[little moat]

Mind telling me how?

[crisp sandal]

it detetcs the objects and move around them in a nav bounds volume

[little moat]

Yeah but how

[crisp sandal]

can hardly show have i have done it since it is quite some code lol

[little moat]

yeah but you kinda need a task for a behavior tree

I'm doing my code in a task for the bt

[frail pilot]

Alright I’ll try it out

[fading snow]

Hey guys, been playing around with translucent sort priority in a top-down 2D game and having trouble with tile maps. I have a map with translucent material, and I feel like I should be able to set each map layer's sort priority...but the setting isn't there. So, my player character is always in front of everything on the map. USUALLY that's what I want, except when, for example, the player walks under an arch that's "above" him. Can this not be done? Do I need to take those elements out of the map and make them regular sprites instead in order to control their sort order?

[jolly jolt]

How to get the blue dot position in order to adjust the "Narrator:" top padding?

[frail pilot]

Alright this achieved the same effect as my normal code, so I'll just try messing around and seeing what'll happen to get the desired effect

[young blaze]

Why does this print "Blueprint" and not the assets actual class like Character for example?

[crisp sandal]

do you guys see any problem in trying to save the location wanna spawn the player there when he dies

[faint pasture]

Are you sure open level doesn't kill this object?

your code might end right there

[faint pasture]

You should do that in gamemode, there's a function to select where to spawn the players pawn at

override that

Even if your current code works, it's just moving the playercontroller. Probably not enough

[crisp sandal]

but how should i do that then simply don t understand why it can t get the vetcor when it is saved and how does gamemode then work?

[faint pasture]

Loading the level probably gets rid of everything, including WBP_DeadScreen which is trying to do stuff after loading the level

either that, or your code works, which only moves the playercontroller. PlayerController is not Pawn

[crisp sandal]

yeah it removes the deadscreen that is true but how does gamemode then work cuz been trying this for the whole day😅

[faint pasture]

do you have a custom gamemode class?

[crisp sandal]

probably not

[faint pasture]

Do that first and set it to be used in Project Settings. in the gamemode class you can choose what pawn players should have and theres functions for choosing where to start etc

then you won't need the pawn on the map, you can place a start spot

gamemode is what spawns the pawn for a player. By default it spawns them at a PlayerStart actor

[faint pasture]

now upen that Gamemode BP up and look at the functions you can override

[crisp sandal]

can t see wich one i can override

[faint pasture]

click the spot where it says override

[maiden wadi]

You need C++ to get font sizings which you then need to convert with the widget's scale if any. That way you can get the pixel height of a single row, based on it's largest font sizing by iterating over the charcters and their styles before the wrapping break. It's not fun, and it's really prone to issues.

That said. What I recommend instead is simply using same font and sizing for name and text so that it lines up anyhow. You'll get a lot of UX issues with multiple font sizes. It's much easier for people with vision or reading disabilities to follow along with same font sizes even if they're bolded in some parts, or different colored than it is to follow different sizes. And there are several cases for aesthetics as well.

[jolly jolt]

I've tried by working with FSlateFontMeasure but I guess I will go for the second option

[maiden wadi]

Yeah, you would need to get every decorator that the text in your rich text is using. Then you would need to iterate the rich text block's datatable of styles for those decorators to pull their FSlateFontInfo. Then iterate through those font infos to get the largest measure.

This will mostly work, except for the text wrapping. You need to filter any decorating styles that characters ONLY on the top line are using.

[jolly jolt]

Yea it will be very expensive in a performance sight

Thank you for helping me figure it out

Anyone have a theory as to why modifying data for my interactable actors would work on cubes and wouldn't on a door?

[maiden wadi]

First thing that comes to mind is construction script, or runtime added components on the door.

[rose vortex]

idk but ironically i just made a functional door lastnight

[maiden wadi]

Doors are such interesting things in gameplay code when you also add multiplayer. They're so.. simple. Yet so much complexity issues arise from them in networking code.

[restive snow]

how do i get RenderTexture2D on my landscape?

[remote schooner]

Construction script is empty, there is no code inside the actor

Techinacally after a bit of testing i came to a conclusion that this is happening on all components that are added via blueprint vieport, like inside blueprint. If i add a component via level viewport, it works just fine

[shy matrix]

I think your best bet is the visual logger

[static turtle]

Hi everyone,

I'm new here and running into a strange problem with Unreal Engine's Animation Blueprint. During runtime, my state transitions seem to skip the set durations entirely, but they still transition to the correct state. I’ve been scratching my head trying to figure this out.

I’m not sure if this is a bug or something I might have missed in my setup. I’ve linked a video showing the issue in action. Any insights or suggestions would be greatly appreciated!

[little moat]

Wdym visual logger

[little moat]

Probably because you did animation select

[dawn gazelle]

Because you're using a soft object reference which means you're referencing the blueprint asset. You want to use a soft object class reference

[shy matrix]

It's a built in tool to debug various systems. It captures a lot of logs and show them in a friendly way. You can enable/disable categories to filter for what you're looking for (eg. Pathing and NavSys). Just google it. It there is an issue with moveto node some warning is most likely logged there

Friendly I mean visually, for most things. But you also can check written logs of all sorts thete

[dawn gazelle]

Ok, you see how it says "Object Type" "World Dynamic"? That's the type of object and influences how the object will respond to "Object Type" traces. If you're tracing for objects of type "World Dynamic" then this object would respond to it.

[static turtle]

well you can see it switches correctly it just doesn't do the duration. there is no way for it to actually switch to and from walking without that state machine. should i not be using an int to set the name and then using the name to switch the state?

[static turtle]

it also seems to work fine with my other animation blueprint for a bike to spawn and its referencing the same exact variable but that one does the animation duration blend when switching which is the weird part

[quiet forge]

Are timelines not useable in widgets? (sry, not sure if this is BP or UI related...)

[dawn gazelle]

No. Timelines are actor components.

[quiet forge]

Oh, I see, is that why I couldn't use them in functions?

or is that a different reason? Oh and thank you for the fast response.

[thin panther]

Latent actions are also forbidden generally

In functions that is

[quiet forge]

I see ^^ thank you so much guys!

[inland walrus]

Any idea one why this wouldn't work?

he's not sensing the player at all

[quiet forge]

I do not understand. If a variable equals "false", you set it to "false"
Also, do you really need that boolean if you have the Event "On See Pawn" already?

If "he" is not sensing the player, the event is not fired? Did you check that? And who is calling this event btw?

Also you should avoid using Tick for whatever you are trying to do

Try to do things Event based that only should happen once a certain time

[lunar sleet]

Also don’t use pawn sensing, use ai perception

[vital cave]

Anyone ran into problems with meta sounds and sound mix class override? The sounds turn off, dont turn back on though.

Ah, thanks for pointing me

[tulip bough]

what would be a simple way to establish whether or not a wall is climbable?

Currently my character can climb everything and I'd like to be able to mark objects climbable or not.

I tried box colliders but they mess with the mantling system. Is there a simpler way to mark if an object/wall can be interacted with?

[dawn gazelle]

You can use tags, or PhysicalMaterials (basically letting you define materials as climbable)

[frosty heron]

You can use the widget designer timeline

If you need alternative. It does the same job.

[old cypress]

Hey everyone! Did anyone encountered a weird bug (?) in UE5 where connections get randomly removed in a file you didn't even touch? For example today after restarting the computer, on the next UE5 editor launch, all the windows that were open in the previous session were closed. All the code stopped working as intended. After investigation I found that in one of the functions in a static library blueprint had some connections removed (including the execution), so I had to restore them. I look at the git history of the file and no changes were made for like 2 weeks to that file, so it definitely wasn't me.

[young blaze]

thanks for the explaination

[pulsar osprey]

have you been using live coding at all?

[old cypress]

nope, don't really have the need for it

[outer sparrow]

Excuse me, can I ask for some help?

Im doing a character select BP

3 characters to choose from

The chosen var is 0 by def until I choose

[outer sparrow]

My Game Mode BP which changes the def pawn (currently none)

[outer sparrow]

And my widget buttons bp

The thing is that despite clicking Paladi or Elf (not Wizard) it will always think I chose Wizard

Basically, Chose var never changes from 0

[dawn gazelle]

Calling "Open Level" essentially removes every object you may have loaded, including your gamemode.

[faint pasture]

Game mode isn't surviving the open level

Simplest approach to what you're doing is to put the char selection data in GameInstance. That persists.

[outer sparrow]

All right thanks!

[old cypress]

wait, I just noticed that all editor settings were reset, so live coding got enabled. Is it the reason?

[pulsar osprey]

not unless you're using it

if you dont do any c++ it has no use

i wouldnt disable it regardless

[old cypress]

why's that?

[pulsar osprey]

disabling live coding enables hot reload which is infinitely worse

[old cypress]

I disabled it because I feel like without it after compilation of my code, I know there won't be any weird glitches

[pulsar osprey]

you close the editor to compile right?

[old cypress]

no...

should I?

[pulsar osprey]

ruh roh

unfortunately in unreal to properly compile you have to close the editor

[old cypress]

I mean, I noticed that if I change anything in my headers I usually have to restart the editor

[pulsar osprey]

if you don't you either are using live coding or hot reload

hot reload is known to corrupt blueprints

[old cypress]

wow, I didn't know that

[pulsar osprey]

live coding can if you have reinstancing enabled and arent careful

if you disable reinstancing, live coding is pretty safe for changing minute things to test them

still have to close editor to properly compile though

[old cypress]

OK, I'll give live coding a go

[frail pilot]

I'd handle combat controls and playing the animations in the third person BP correct?

Alrighty

Thanks

[old cypress]

thanks for the info. Although I'm surprised that live coding is the preferred methond of compiling

I kinda got an impression that its' purpose was to make compilation time lower

which is not really an issue for me, since the project compiles fast enough with the hot reload

[proven loom]

why would a dynamic multicast delegate not be hit in blueprints even though it's being called in C++?

    DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FCharacterDied, ABastionCharacter*, DeadCharacter);

    UPROPERTY(BlueprintAssignable)
    FCharacterDied OnCharacterDied;

    UFUNCTION(NetMulticast, Reliable)
    void Multicast_JustDied();

void ABastionCharacter::Multicast_JustDied_Implementation()
{
    OnCharacterDied.Broadcast(this);
}

when i put my breakpoint on OnCharacterDied, there's nothing assigned to it. it's like the BindEvent is not happening, but I've confirmed it's being hit in BP

[frosty heron]

@old cypress https://landelare.github.io/2023/01/07/cpp-speedrun.html

Is the delegate binded in the target machine?

Probably much to do with the networking logic

@proven loom try binding and broadcast without multiplayer?

Then you will know if the delegate simply wasn't binded into target machine

[proven loom]

it's standalone

i made it a function and a BlueprintImplementableEvent and now the issue is gone 🙄

not sure why the delegate was not being bound

[frail pilot]

What would I do to make it wait for the animation length before allowing other animations to play on button press as well as going back to the idle animation instead of freezing at the end of the animations and no longer playing the idle and walk animations?

[maiden wadi]

That == check looks sus.

[proven loom]

it was getting hit 🤷‍♂️

[maiden wadi]

The == or the code after it?

[proven loom]

after

[maiden wadi]

You have the same check in the BIE? What's it checking against?

Cause in the above image, It's asking if something == nothing.

So unless you passed the bottom pin a null pointer, it can't run true.

[proven loom]

😮

i don't know how i missed that! thank you! i'm using a BlueprintImplementableEvent now and dont' feel like going back but i'll keep it in mind for next time!!

[maiden wadi]

Yeah. 😄 BIEs are nice. But do be careful using them. They can very quickly be anti patterns.

[proven loom]

for sure! makes sense. i really only used it this time to get over this problem and move on

[maiden wadi]

A good example is, you need a widget, the character, some manager, etc all to do something when the character dies. Using a BIE, the character has to know about all of those things rather than those things being able to simply bind the delegate from the character.

[maiden wadi]

You need some sort of state machine or variable, or ability system. GAS for instance could run an ability with inputs that would play the animation and finish the ability when done, you can't rerun it until it finishes and other things could interrupt it using tags and such. You could also make a state machine that enters that area when you start an anim and won't allow you to leave or enter it until it's done. Or last you could maintain a simple boolean of something like "is playing animation" and check it before allowing another, and unset it on anim finished.

[frail pilot]

Ok, so would I put my animations (the boxing ones) into the same state machine as the movement state machine?

Wait nvm I'm using an animation BP for the movement

Not a state machine

[maiden wadi]

State machine isn't always animations specifically. It's just a tree of logic that allows you to enter a different state based on conditions.

[iron idol]

can you not use plane cut on models? I made a cut but when i exit modeling mode the cut is no longer there. When I go back into plane cut it seems to remember where I cut it. Am I missing something?

[frosty heron]

You essentially forfeit your anim blueprint when you use the play animation node.

Look into montages instead for animation like firing or slashing

[lunar sleet]

Hit accept changes before you exit it

[frosty heron]

You are probably talking about fracture tool and you only view the representation of the model when it's fractured.

[iron idol]

I did hit accept. And I'm talking about the plane cut feature in modeling mode

[lunar sleet]

Also make sure if you select keep inputs that you move the old version away

Beyond that I would just restart UE 😀

[iron idol]

I have 🫤. It should be working. like when i got back into modeling mode the cut is there. i try to cut again, accept again and exit back out and there is no cut.

its as if the engine knows I made a cut but is not applying it

Or at the very least the cut is there, but it only shows that its cut in modeling mode.

[lone garnet]

Is there a way to measure distance between 2 seperate mesh component sockets. So for example a gun with a socket on its iron sight, then on a separate red dot mesh with a socket on its red dot. Measuring the distance between the socket on the red dot and the socket on the gun iron sight. This is so I can adjust the gun from looking down irons to looking down the sight with a simple offset

cannot use world space either

[frosty heron]

why not?

Math totally not my thing, but maybe you can just subtract the 2 component location then get it;'s length

try using the result to offset your view

[lone garnet]

Cant use world space because changing the direction im looking impacts the point of measurement for some reason. Meaning the slight changes make the sight not centred.

Ill see what your suggestion reveals

Im assuming you mean world location?

[gentle urchin]

Does it center itself a bit late ?

A frame late by any chance

[lone garnet]

The issue i have mainly if i dont constantly tick its offset, is that the offset is a tiny bit different if i look up vs down vs straight ahead.

[gentle urchin]

Ah ok

[lone garnet]

I fully dont understand why this isnt a common problem for fps games. I have no idea how they dynamically sdjust based on sight

[shy matrix]

Did you maybe cut an engine shape/mesh?

[eager thicket]

Is it possible to do something like a "named reroute" on this? I basically want to clean up my code from this node without explicitly creating a variable

not a reroute but something that's functionally similar to a named variable

[lone garnet]

@frosty heron Result is the same as what I had previous. I should elaborate as well now I think about it. The issue is that I have the adjustment on tick to account for the slight differences in offset for a more accurate position, but alongside a procedural recoil plugin, the tick adjustment is causing issues for the procedural recoil. So Im mainly wondering how I can have the sight offset not happen on tick

[frosty heron]

never heard of anything like a named reroute but why does it have to be messy like that?
Make more reroute node to clean up

[dry sleet]

If you don't have any latent actions that need to be in the Event Graph -- just make a local variable.

It's what they're for.

Named reroutes in other graphs end up being pretty much the same thing, the overhead is 0.

[last ingot]

Hello, I'm trying to make like a circular fade in and out transition using widgets, except I want to use my own mask. The issue I'm currently facing is that I created the material and the opacity mask is working to the shape I wanted, and is controllable with a parameter, but when scaling down the image it scales to the top left rather than center wise.

this is the material

and this is how it appears at full scale

scaling it down goes to the top left rather than center, help?

[trim matrix]

I'm not exactly an expert with materials but I believe from past experience the centre point will be the width and height halved. If you're using 0,0 that might explain why it's going to the top left (I believe that's considered the origin)

[last ingot]

Yeah, I already done that

[crisp sandal]

is there a way to clean 100+ bps nodes all at once have depricated movement in there from the free enmies pack for ue5

[dense schooner]

Use this console command au.3dVisualize.Enabled 1

I mean in blueprint at runtime.

[ionic ore]

how come i cant do this compared to the other picture?

[lyric kelp]

Hello,
I have created a Widget for my Archviz Project
I would like when i click on one button to apply a trigger volume to hide others objects.
I would like to know how to set my trigger volume.
In the second ScreenCapture i duplicated an already existing event. The things is the section view in this case is depending on a box (poi selected). What i would like is to avoid chosing a POI and assign an existant trigger volume in my viewport
Any suggestion/help?
thanks

[ionic ore]

figured it out

[dense schooner]

So you want to hide and unhide objects in the level when selecting a button?

[lyric kelp]

exactly actually its working
poi needs to be set on POI Filter then following instruction once you clicked on the POI you can activate section view mask

[dense schooner]

Try this

each group of actors should have the same tag

[lyric kelp]

i'll try it,
in case my meshes are bigger than the size on a floor (exterior structure) i guess then all the mesh will be ihidden?

that's the actual event when i click on the image for section view.
I thought creating a new poi called POI_section
Once you select this type of poi you only have to choose the trigger volume and then may be just add a not visible material in game but once you click on the widget it calls the trigger volume and mask all the object inside the trigger volume
(trigger volume is linked with a MPC_SEctionMask material set on all my object)

[dense schooner]

Yes, it will hide all actors and mesh components together

[dense schooner]

Using a material is another solution, the solution that I suggested is much simpler and hide the objects immediately

So in that solution you select the level 1 button for example, you get all actors with Level1 tag and unhide them after that you get all actors with Level2 tag and hide them, same for Level3 and Level4

[lyric kelp]

perfect, i'll try it asap, and come back to you, thanks!

[marsh sonnet]

Hey y'all! Is there an easy way, not using tick, to run one node (an animation thing, using paperzd), until the character movement is no longer falling, and THEN run the other node? Without a timer, something that I can put in there to temporarily watch it until it changes, then stop watching?

This is for an enemy: I want it to not implement the "HasDied" logic until it finishes the animation that pushes it across the screen

[spark steppe]

why on earth would you do that in the first place?

hard coded asset paths are prone to cause issues at some point

[ionic ore]

debug

[spark steppe]

you can just pick the class from the dropdown?!

[ionic ore]

mod

[spark steppe]

or promote the softclass to a variable

[ionic ore]

i dont have the class

i was grabbing it on game runtime

[spark steppe]

is that for your own game or another game?

[ionic ore]

another

[spark steppe]

then i would bug them about providing a decent modding API

because they clearly don't

[ionic ore]

its fine how it is

dw bout it

[austere scarab]

I have been working on an equip function for my character and for the life of me I can not figure what is wrong. When I press my equip key, the anim montage twitches and then cycles through its animation but is in the corect position once its played through its cycle. my character changnges animations properly as well to idle with weapon, walk with weapon or no weapon etc. Its just the equip and unequip anim montages that are the issue. I put this together based on some tutorials and forum posts, so I am sure that's the reason why its so jank. Any words of wisdom would be appreciated

[proven loom]

following up on this: yeah BlueprintAssignable is now starting to break randomly in other blueprints. i started a new project and wanted to lean heavier into blueprints but i'm going to pivot back to cpp since it's more reliable. i made sure that the comparison was correct in this case and the blueprints were still not getting hit with BlueprintAssignable. so that's that

[maiden wadi]

I would maybe check up on that. In the years I've done this, I use delegates a ton. I'm heavily against BIEs for a lot of things unless it's specifically only a hook for the child class. But I do a lot of UI work, so it most often is necessary to have a delegate. If your delegates are not running then simply put they are not bound to the object broadcasting them. Either you bound to the wrong object, broadcast on the wrong object, or you unbound the delegate somehow on accident such as an UnbindAllEvents call.

[hushed panther]

I have been trying to create an inventory system for my game for some time now. I have created a structure to hold all of my variables. in my inventory system I can double click on the slot to equip the item if equip able. I can alos pick up enemies by clicking a button and creating a line trace. When I equip a wepon I attach it to my character. But I dont want to be able to pickup an item thats already in my inventory and equiped. I need to know if I can set a variable from my struct in the slot widget to do this. I can post more pics if needed

[frosty heron]

using bool like that is pretty nasty imo

a sword or weapon can be reference and you can just check if it's null to deem that something is equiped or not

Also if you don't want to pick up an item that is already in your inventory or equipped, then just a function for that.

IsItemEquipped or IsItemInInventory.

[lyric kelp]

@dense schooner works wonderful thank you very much, you legend

[frosty heron]

I would refactor what you have atm. Sword, potion and shield should not be a bool.

[hushed panther]

Im kinda new so how would I would I check if this instance is in my inventory for the funciton

[frosty heron]

pretty sure everyone would use component as well for inventory. Make it more generic so it works beyond the player character like that. No casting should be needed

anyone should be able to use the inventory so don't tied the code with the player character

well you wouldn't just have 1 item in your game right? So you will need a list (array) of items.

[random schooner]

hello I'm completely new to unreal engine or game engines entirely I've been watching a lot of videos and I'm trying to make a "building" mechanic. the goal is to just place basic objects but for some reason every tutorial that i watch i seem to always mess up the line tracing (most recent) and the object mesh wont spawn in general or if i does its off in neverland clipping. any advise would be amazing.

[spiral kraken]

Fun fact of the day!

Did you know that if you create a function with a Struct input variable inside of a BP, create a child of that BP, and then try and override that function in the child you will essentially lock that particular struct from being edited (adding, removing, renaming or changing the types of variables), causing the editor to instantly crash out whenever you try and make changes in that struct? I found out the hard way.

Anyone else ever had that issue? Or is my setup just broken?

ALSO, did you know that Unreal do NOT like it when you try and dabble with arrays of text? I also found that out the hard way.

Until next time!

[frosty heron]

Don't use blueprint struct if you do, they are broken and will stay that way

as for arrays of strings, I have no issue with them

not that I used it anywhere right now but in my old project, things work as is

[spiral kraken]

Broken in which way? The structs work flawlessly for what I use them for and never had any issues, EXCEPT for that scenario with an override...

I misspoke, it was supposed to be arrays of text hehe. I had to redo like 3 days of work to utilize strings instead of text.. Was troubleshooting for like 2 days straight before I found the issue, UE 5.4 didn't want to add anything to the text arrays, so they always turned out empty

[frosty heron]

Blueprint structs broke in many way. It's flawless to unsuspecting victim until they stop working. You can just look up search history in this discord and type blueprint struct.
One of the most common error is unknown struct error, and some error leads all the struct values to be defaulted. Things break easily especially when you add or remove a variable from your bp struct definition.

The best way to use struct is to declare them in C++, they don't come as a minefield. I was a victim of bp struct my self and had to re-do a lot of my work.
Switched to struct declared in cpp and I never have to look back.

[proven loom]

yeah i'm unsure why they're breaking. to be clear, i've also used them extensively in my previous project with a client/server infra. this new project is a standalone project.

interestingly, completely by chance not intended, i happened to fix one of the broken cases with this code:

    AsyncTask(ENamedThreads::GameThread, [this]()
    {
        OnCharacterDied.Broadcast(this);
    });

so maybe the issue is that the broadcasts are not executing on the game thread... for some weird f'ing reason

[native canopy]

why the gun not attach to the hand when i disable simulate physic? i already use AttachComponentToCOmponent

if i diasble physic from obejct detail the gun attached fine

[frail pilot]

Ok I've made two iterations of how to make a movement system by changing a string name then increasing the max acceleration but none of them seem to work. It only prints a single string and doesn't go through them. Am I overcomplicating this?

[frosty heron]

don't do this

[frail pilot]

How come?

[frosty heron]

using string is a terrible idea

[frail pilot]

Ideally this would be for a boxing game, so I wanted to have three different movement options

Oh ok

I mean I am starting to see that currently

[frosty heron]

GameplayTags or Enum

[frail pilot]

Oh ok

Thanks

[iron idol]

is there a node for spawning in a static mesh?

[frosty heron]

You want to spawn a static mesh component or a static mesh actor that has a static mesh component?

[iron idol]

idk. just a straight up static mesh. i've realized that i can prolly make an actor BP, add the mesh to the BP and spawn that though

[frosty heron]

if you don't need anything custom, just use the SpawnActorNode and spawn a static mesh actor

if you want to spawn a static mesh component from an actor , you can use the add static mesh component node

[iron idol]

Yea, I tried that at first and the mesh wasn't showing up. It's fine though, like i said I just made an actor BP with the mesh.

i been using unreal for like 2 weeks lol

so you can use AIMoveTo

and you need to put your shit in a NavMesh

[limpid thorn]

thanks

[lone garnet]

what am I doing wrong?? 3 days ive been trialing and erroring aim down sights. I have fps arms with an aim animation that lines up the irons to the center of the screen, all I need is to lower the animation based on an attachment. But it needs to be dynamic because the same sight could go on multiple weapons and the system has to apply to those multiple weapons. It should be as simple as measuring the distance between a socket on my sight and a socket on my iron sights and offsetting by that amount. But it causes issues.

If not performed on tick to constantly adjust, small offset changes apply based on look direction so the sight no longer centers itself.
measuring between sockets of different meshes is something I cant do or am doing wrong. if done in world space, the value is too large.

is it something to do with my arms rig? could that impact things?

I feel like it must be something sooo basic Im not acknowledging. Or the world is gatekeeping fps aiming from me 😆

[frail pilot]

Ok, I'm having problems with this idea. I'm trying to use gameplay tags and watched Matthew Wadstein's tutorial on them but it never covered how to change it like this dynamically

I'm watching a yt tutorial on inventory system (Native Coder) and it seems that the actor won't get destroyed when i play as client. i kept rewatching the video and cannot find any missteps.

[frosty heron]

no one can say without knowing what the interface does

but in any case, that code will destroy the actor where that blueprint reside

I believe that's not intentional

[dense crest]

what do you mean by not intentional?

[frosty heron]

Read your own code and tell me if that make sense

If the input is in the player controller, then you are killing your own brain.

If the input is in the character then you are killing your character.

Not the item

[dense crest]

the code is written in the item with input enabled and did set ownership to the player

[frosty heron]

Oof, if that's what the tutorial do, I will be damn

Imo there are a lot of things to unlearn from youtube. Especially when it comes to multiplayer bp tutorials

1. Don't handle input in the item
2. Don't use legacy input.

This is pinnacle of shit code, no offence. There are soo many ways to do interaction in mp and this one take the worse possible approach imaginable.

[dense crest]

yeah, i did have a feeling that it was not the best way to do it

[frosty heron]

That's legit the worse way possible.

You don't want to give ownership most of the time. Only edge cases because this is vulnerability.

Interaction can be kept simple.

If you don't care about cheating and you trust the client, then let the client trace locally, then server rpc the object it hit.

Then server can run the interact logic. With the passed actor. Such as, giving item to the player and destroying the item actor.

[gusty crypt]

Hello, i want to make an double jump behaviour like in ghost n goblins, but i dont archive it exactly. First i let the player jump like normal, then with a flip flop, the second time the character gets launched. Works so far, but either the character only jumps up or to the direction i moved before, basicly i cant switch direction on the second jump. Can anyone help me?

[gentle urchin]

I take it you're not aware that CMC has double jump integrated

[gusty crypt]

uh, no :S

but still, doesnt solve my issue

[quiet forge]

does it work for material parameters?

[ruby glade]

Hello everyone, this is the noobest math person in this forum 🙂 I want to check if a variable is increasing or decreasing over a period of time. I did the coding for getting if the value goes up or down but I'm have no idea how to check it if the value is increasing in a period of 2 seconds. I want to trigger an event if the value goes up for 2 seconds and another event if the value goes down for 2 seconds. Is there a tutorial or if you could spark an idea that will be awesome. Thanks.

[maiden wadi]

Not entirely clear on what you want. You have a float that is changed constantly, and you want to know if it goes up for two seconds, and stop the time if it starts going down, and then start a time for it going down for two seconds. And if it manages to go in either direction for two full seconds, trigger an event?

[ruby glade]

Hey thank you for responding. I have an gravity/physics moving object. If the object is falling, my variable value is decreasing and If the object goes up, my value is increasing. I want to trigger an event if my value is increasing in a timespan of minimum 2 seconds, if so, the trigger is activated. Same, if the object falls for minimum of 2 seconds, another trigger is activated.

[maiden wadi]

What is the object in question and where do you need the event to trigger? Also how many objects in general?

Initial thought is to just get it's velocity each tick and track a LastFrameVelocity of your own.

If current frame velocity Z is near zero, set a float to current game time. You'll use this float to track when the object started to go up or down. CurrentGameTime minus this float gives a value of how many seconds passed since this object started moving in a direction that you'll set when it starts going one way or the other.

For directions you'll need to track last frame's velocity. At least it's Z value. You'll Sign this to current frame's velocity Z value and the last frame's Z value. If they're both the same then it has been going in the same direction. If it's not then you set the float you use to track time. If the object's velocity is moving, then you don't do anything. If it is moving then check that time float against current game time to see if it's > 2. If it is then trigger your event.

[ruby glade]

Thank you for this Authaer!

Level streaming not working while in spectator mode. Do I need any extra setup ?

[fading raptor]

hello everybody ! i'm trying to do a simple system in which the enemies are spawned then they start following the player but even if they spawn (and despite having a navmesh in my level), they never start following the player, does somebody can help me ? here are the screens of my code : (since those screens at tried firing the chase player on begin play of enemy & target actor is now get player character)

[storm solar]

you have to debug the ai move to.
Do they move to player if they are spawned by the event, or put in the level scene?
What debug info is in the move to data?
https://youtu.be/ma2BtPOVN-g?list=PLNBX4kIrA68lz8GSxTQKX_0B23tHP6Bl9 this playlist has a lot of info about AI and tracking.

[ruby cobalt]

hey i'm starting to like the draw debug stuff aesthetically.. if i get rid of the Development Only mode of the node they will work in the packaged exec, correct?

[mental trellis]

Depends on the node.

It might just be editor only... and for good reason.

[ruby cobalt]

i guess i can rebuild similar stuff using GUI

i don't know the gui editor well enough and I'm having trouble placing it properly in space

[gentle urchin]

They're relatively slow once you reach a certain amount

[ruby cobalt]

the debug stuff?

ok good to know

[thin panther]

yeah the debug stuff tanks frames.
Put it this way, drawing a persistant line trace each frame for a couple of minutes slowed me down considerably with noticable stutter.

[ruby cobalt]

are there ways to switch between orthographic and perspective? and like interpolates the views?

I,m using cine camera and it doesn't have ortho

[keen crystal]

Hello! I’m facing a rather specific issue:
I want a name above my character’s head in my game, so far so good, but:
If I set the widget component to screen space instead of world space, it doesn’t display on certain clients (whereas in world space, everything works fine).

To be more precise: everything works fine for the clients— they all see the nametags —but the server doesn’t see the clients’ nametags.

[hexed owl]

Is there a way to switch between a static or skeletal mesh in the heirarchy?

My issue is I have skeletal frames for things like bi-peds, but then I have static meshes for the tank bodies.

[mental trellis]

Add 2 components, 1 static and 1 skeletal.

[frosty heron]

From memory, you can get the value of the timeline, so you can use the float for anything including setting float material param

[lavish elm]

To be specific, you're using a Listen Server host and the Host is unable to see Client name tags?

[silent stag]

A component on a vehicle is not working properly after possessing the vehicle with a character. What could be the reason for this?

[keen crystal]

exacrly

whereas when i use « world space » everyone can see every single nametags

the problem seems to be with screen space

[frosty heron]

Nu uh, I use screen space for nametag and no issue with client or listen server

[hexed owl]

Yeah, I tried that method, but then I have to duplicate each of those children starting at the static/skeltal split. No worries, I just cheated and eliminated the static meshes that I have for movement components. 😄

reparented the BP back to character, and will move forward from there, no need to be fancy at this point in the game 😛

[lavish elm]

@keen crystal yeah I agree with @frosty heron with what I've heard so far, i can't think of any inherent problem with screen space that would prevent it from showing on ListenServer host.

Do you have any screenshots of logic for your widgets?

[frosty heron]

Widget is local anyway, how you display it got nothing to do with networking. Only attaining the data is part of networking.

[keen crystal]

well it started not working since i switched to 5.5

it worked in 5.4

[restive snow]

I'm trying to get the game to know where the mouse cursor is clicking on the landscape, I am using a Texture where each RGB color is a tile. (In my database)

[frosty heron]

debug, actually find out what's missing

it's most likely something that you do imo

[keen crystal]

well as i said i didn’t change anything, it started not working when i switched to 5.5

[frosty heron]

@keen crystal find out what's missing in the first place?

check if the server getting the data it need

see if the client's name reach the server and is stored somewhere then check if its being displayed

at this point you are just deducing instead of figuring

90% of the case people complained about engine bug ends turns out to be their own doing, just saying.

[keen crystal]

i tested with no names or else, just a default widget with a text in it that displays « Text »  and still its invisible for the server

ill try to look deeper but i tried everything

[frosty heron]

I mean the client and server both using the same engine version

and the node they are running is the same

it really has nothing to do with server vs client tbh

it's probably what you do in the server instance. Check if the component is visible for the server

Event tick -> Has Auth -> Get Name Widget -> Get vissibility, get hidden in game, etc

anyway gotta to work, gl

and maybe post what you got in #multiplayer

[graceful gust]

2 issues:

1. why is the cast failing?

2. the line trace doesnt collide with the enemy

it worked before i changed the mesh of the enemy

[lunar sleet]

Take better res screenshots and also it means whatever you hit is not the right actor so figure out what comes through

[silent sand]

Hey guys, apologies if this is either the wrong section or just a really stupid question but im trying to make a first person character that sits inside of a rocket, it needs to be able to rotate on any axis while the player camera is also able to look around while keeping whatever rotation the rocket is in. So far i can either get the camera to lock onto whatever rotation the rocket has however its stuck in place, or i can get the camera to free look but it doesn't follow the rotation of the rocket. I've tried pretty much every combination of settings with spring arms, use pawn rotation on/off, inherit pitch/yaw/roll etc, if anyone has any ideas i'd be much appreciated (lemme know if you need screenshots of the blueprint)

[sweet frigate]

Nothing is connect to ==

nevermind

[gentle urchin]

You probably just want to cast

And ignore the ==

As thats instance specific

[graceful gust]

what about collision?

the trace goes right through

[gentle urchin]

Wrong channel/collision setup then

Missing collision volume ?

[graceful gust]

like this?

[gentle urchin]

Yes

[graceful gust]

where do i check?

[gentle urchin]

On the mesh

Or in the bp class if theres other volumes in it

[graceful gust]

where exactly

looks like this in the blueprint

if it matters i changed it from a static mesh to a skeletal

[graceful gust]

got it working. set collisionpreset to blockall

[mild galleon]

Hello!
"Trace Under Mouse" doesnt work with Multiplayer.
I think its because i have many controllers.

[fiery vortex]

Has anyone had issues with getting SetText in UMG to work in 5.5? Mine refuses to update the text but works in previous versions.

[maiden wadi]

We haven't moved to 5.5. I tried to update but ended up getting some critical check crashes in AI nav code. But I don't see anything changed in Textblock code that would affect that for the 5.5 release. :/

[ruby cobalt]

i'm trying to spawn instances and remove them shortly after.. but doing this crash the editor.. i must not be doing it properly..

i need about 10 of them.. maybe I can just toggle visibility and move them around instead of creating/deleting?

[tepid fox]

Anybody knows a way to use different geometries for a Widget Component? I want to make some sort of warp

[crude dew]

Can someone tell me why my character juust keeps floting up when i press F please ?

Its almost like the Stop Jumping doesnt trigger and make the character fall back to the ground again

[dawn gazelle]

What's your Movement Mode and gravity settings?

[crude dew]

I figured out it was due to some settings on the Character Movement Compoennt 🙂 thank you for the reply! 🙂

[ruby cobalt]

i'm spawning planes where my line hits.. but I want to rotate them to be perpendicular to the normal.. not sure how

i tried addig 90 but somehow i can't use that node

[pale obsidian]

Can you store BP logic inside of components? For example, when equipping a weapon, add/remove that logic as needed. Feels weird having all this empty weapon logic in each of my characters.

I want modularity

[dawn gazelle]

That's what actor components are. Logic you can attach to an actor.

[heady radish]

Hi everyone. Not sure if this is the right place to post but I have a game where the player character sticks shelved with items at the end of their shift and I was wondering how I would go about doing this? I already have an interaction blueprint system I just need to know how to build the shelf system and item storing.

[pale obsidian]

Can you add and remove at runtime? Im concerned with memory use as well

[fervent crypt]

It's kinda of long video but if any one help me with this bug I greatly appreciate it. (Idk if first upload work so please don't count it as spam)

[dawn gazelle]

Yes, but I wouldn't be too concerned with the memory footprint of actor components. Assets like audio, meshes, etc. are 99% of the time going to be larger than any single blueprint class in memory and there's a different means of managing assets being loaded.

[hallow saddle]

Is it possible to create a function where you can "collapse" the output variables like shown in the picture? I've seen that it can be done in C++ by changing the metadata but is there a way to do it with BP only? I have a function that I plan to put 10+ outputs and it would quickly clog up my blueprints

[jovial steeple]

Not in blueprints, you would need to do this in CPP with the method you described.

[crude dew]

Only thing i could possibly think of is theres a delay which I assume it,s using a network to populate the leaderboard, Do you do a check to ensure that the network is fully loaded before ? I,m no professional just an idea. (I,ve not done much android stuff personally in UE5, So shooting in the dark here in hope to help) xD

[jolly epoch]

im having an issue with collisions and i cant figure out why. whenever the enemy runs into me, it just pushes me around but when i walk into it the collision event works fine.

theres a video of it if it helps

[crude dew]

If you are using a Character blueprint I would check the collision on the Mesh component,, Capsule Component and anything else you have. Im not sure how the engineworks in detecting on who hit who first (maybe done by a velocity check but who knows?!?) I,ve had this sometimes too.

I usually end up creating 2 custom collision channels (Player and Enemy and then set them to overlap each other (unless you need to process a hit event))

[faint violet]

I know this is probably a common issue with easy fix, but I can't figure out the google search terms.

[crude dew]

Overlapping Actors are Actors the receiving node is expecting Loot Holding Actors

Im not sure if Get Overlapping Actors Class filter is "Find me all X Class" or Filter out X class's

[faint violet]

guess it uses a generic actor ref instead of updating the output pin; and idk a workaround, so I guess I will have to redo the stuff in inventory handler

[crude dew]

https://dev.epicgames.com/documentation/en-us/unreal-engine/BlueprintAPI/Collision/GetOverlappingActors (Odd it does say "Returns actors of a specified class" but you can see on your node it says Actors are not Compatible with Loot Actors")

[faint violet]

ya

is there no way to transform an ouput or refilter?

bruh

[pallid dagger]

you can create another array, filling it with Actors each casted to desired type, tho this whole situation looks weird

[crude dew]

I would probably go this route

Not tested this but it takes all your overlapped actors attempts to cast to your class and if valid it,ll throw it into the new array of "Your Class"

but give you the general idea of how i would approach it.

@pallid dagger I agree not sure why the Class Filter would not return Actors of the Class you specified :S

[pallid dagger]

I guess it's better to filter original result manually by success/fail cast

[crude dew]

I think my bp code might work but someone more experienced than me could tell you 🙂

[faint pasture]

Because it returns an array of actors

It's probably technically doable to template it to change the output type but that's probably more trouble than it's worth

[crude dew]

@faint pasture Why does it say returns actors of specified type on the UE Documentation I would guess it,s a bug or not implemented properly, But its not too hard to convert them anyway to your specified class as you said 🙂

[fiery swallow]

but it does exactly what it says it does

I think it's just an english interpretation thing

because it does only return actors of that class or subclasses

it just returns it as an AActor

[iron idol]

How would you remove a specific item from an array without removing all duplicates as well

[fiery swallow]

remove index

[iron idol]

ah, i think i see. thanks

[jolly epoch]

turns out i just had the collision capsule set to block pawns instead of overlap so thats why i was getting pushed. atleast i wont make that mistake agian probably

[chilly crane]

I need an opinion, is this a good implementation of DLSS3.7? It's my first shot, and I'm still new to UE. Any thoughts on doing it better are welcome!

https://blueprintue.com/blueprint/jdndwdfj/

[faint violet]

@crude dew@pallid dagger Thanks for the help. Turned it into a sadly hardcoded libmacro. It seems to work, as my delete interface can delete them from the world.

[faint violet]

edit: forgor to clear it. but it works.

.
Does anyone know how to do an input variable based cast?

[frosty heron]

wdym by input variable based cast?

[frosty heron]

What is this and why? I feel like there's no need to make the macro at all

not to mention you hard code a string to convert something

[faint violet]

I don't need it, but it makes it easier, and I don't have to add another junk variable/function/macro to whichever actor I need to do it in.

[frosty heron]

make easier for what though? You already got the filter class if you want to filter the overlapping actors

[faint violet]

oh ya, these dont work for this #blueprint message

[frosty heron]

I see but resorting to macro with a hardcoded string is not ideal imo

[faint violet]

I cant think of anything, because interfaces dont support wildcards.

this might be one of those c++ moments

[frosty heron]

in cpp you can use template

[maiden wadi]

By their definition, interfaces are wildcards. you run them generically on any object and that object handles it's own thing.

If you want to generically call a function on an actor that will have very different logic per actor, and you don't need state, use an interface.

If you want to generically call a function on an actor that will have different or identical logic on separate actor types, and may or may not need to maintain state but don't want to do it on the actor itself, use a component.

[native canopy]

is this efisien for performance?

[gentle urchin]

No

If you want to let the weapon track the ammo count (for whatever reason), you'd want to setup an event dispatcher that the UI can listen to. You obv dont wanna fetch Ammo on tick , as it serves no purpose being there

so whenever a weapon is swapped you want to unbind from the old dispatcher, and bind to the new one

[silent stag]

When possessing an actor class with a character, the owner remains the character, but relevancy doesn't work correctly. How can I solve this issue?

[true crypt]

Hi, some weird things are happening in my animation. The loop section is supposed to loop and it does, but the anim notify AN_Stop heal is being triggered during the loop while being obviously out of it. Does anyone knows why?

[heavy lion]

Let's say I'm using an interact interface for multiple different types of actors. Doors, pickups, beds and so on. That is working fine. But then I want to get some information from the actor I'm interacting with. How would I go about doing that without a cast

A bed for example. I will use the player controller. Which interfaces with a function on the bed. The bed will have a comfort level for example. I want to get that information in the player controller without casting or creating a link.

The bed doesn't know about the player

[restive snow]

what is this?

I forgor I'm sorry

dw i found

[empty badger]

i am using the multi sphere trace for objects node
i believe due to multiple collisions its hitting the same actor multiple times and add it to the out hits array
i would like to change this so that it would only add a uniqe actor to the array
how would i accomplis this

[restive snow]

how to connect these two?

It won't allow me to connect

[gentle urchin]

It shouldnt be the controllers responsibility to house the code for what some X interactable does

It should be the X interactable itself

Or Usable or whatever you wanna call it

[trim matrix]

you could check object names of existing hits 🤷‍♂️

Or multi trace with overlap

I think that only logs an objects once on hit

[gentle urchin]

AddUnique

[empty badger]

ahh ty add unique did the trick

[olive yarrow]

I don't really understand Enums or Structs - and how i can use them to create my weapon inventory.

Right now i'm inefficiently using bools -_-

Any body got leads on a tutorial (i checked out our tut thread)?

[thin panther]

enums are just named integers
structs are just a collection of variables

[faint pasture]

interface call with a return

[faint pasture]

Imagine if bool had more than one state, and you could rename the states

bam, that's an enum

[olive yarrow]

Cuppa, mornin' good to see you again!

So the struct would hold all my integer variables stored in the enum..

I'm guessing i should add the item struct variable to the weapon blueprints? Heck even after that i'm a little lost

[faint pasture]

no

[olive yarrow]

the imagery genuinely does help the envisioning

[gentle urchin]

This is gonna end with a superblueprint doing everything

[thin panther]

Your item struct would have everything that you need to define an item.

Perhaps an icon, a class to spawn, a durability value and a stack size for instance

[faint pasture]

An item struct would look a bit like this

[thin panther]

enums you can use more easily to define state. Say you had a weather system. Weather has different states, so you might control the current weather with an enum
The enum might have values such as Clear, Rain, Snow, Clouds, Thunderstorm

Then in your weather system you can do different things based on that enum

[olive yarrow]

oh word, don't need nunna that. So i can focus on just structs?

[thin panther]

Yes.

Have you ever used a line trace?

[olive yarrow]

I use those now!

[thin panther]

You know that hit result you get?

this lil thing

[olive yarrow]

i've got it broken currently

[thin panther]

Yep, just want to know you're familiar

it's a struct

[faint pasture]

Struct is just a wrapper on a bundle of variables

[thin panther]

It just contains a bunch of information related to what a "hit" is

[olive yarrow]

OH!

[faint pasture]

You know how a vector has 3 floats in it

struct

[thin panther]

"breaking" a struct just means taking it from the dark blue pin, and showing all the variables inside of it

so you're already familiar with how they work, you just didn't realise it :P

[olive yarrow]

hell yeah!

So from my Hit Actor when i connect with an equippable item - currently i'm using tags and bools so it's messy and long. How would i implement my struct and my varying weapons into that (or is there a tutorial somewhere if you've not the time this will likely take me to grasp)

[thin panther]

so you want to take the hit actor, take it's item information and put it into your inventory system?

just to clarify what you mean here

[olive yarrow]

Yeah, sorry - contextually it's a bare bones FPS (two weapons at a time) - currently all my weapons are seperate actors/children from the baseplayer.

my brain just froze.

right now i use a hit actor to check if hit actor has tag - actor is then spawned onto my player actor - if no it goes on to check the next tag/bool.

I thiiink i can figure out how to limit it to two weapons but

crap

lost my train of thought again

[thin panther]

It's ok, take your time

Is it a game where you can pick up items into a classic inventory (like Minecraft)
Or is it 2 weapons. If a slot is free, put weapon in that slot, otherwise drop weapon and replace it with picked up weapon, like CoD

[olive yarrow]

Ah! like COD

i am seriously so sorry, you've been typing for awhile

[thin panther]

ah! now we're getting somewhere.

Personally, I'd start by making your item struct. For just a weapon I could think of a few important bits of information: The weapon class to spawn in, and possibly things like it's current ammo, it's ammo in reserves, etc.

The stuff that wants to stick around when you change weapons.
Now, lets say your player has an array of weapon info structs. It tracks the current equipped weapon by storing the index of the weapon info when you switch. When you pick up a new one, it tries to find the first empty slot in the array, and puts the weapon info into it. You can define what an "empty weapon" is, by say making a struct with all default values and no weapon class.

If all the slots are full, it instead resorts to replacing the current equipped weapon index with the weapon information.
Whenever you update the inventory though, you need to handle changing the current equipped weapon, if you've changed the slot you were holding. Don't want your inventory to say you're holding a Glock 18, when you've actually got a Barret .50. So, whenever we make a change to the inventory, we make a note of the slot in the array we changed. If that slot is equal to our equipped weapon, destroy the equipped weapon and spawn the new one.

When a weapon shoots, it checks the weapon information struct for the info it needs. I.e, if the current ammo in the mag is 0, reload, subtracting the ammo in mag from the total in reserves. Then when you switch weapon again, destroy the current weapon, spawn the new weapon. Because you're tracking all the persistent information in the weapon struct, when you switch back, it can "remember" the ammo it had in it's reserves and the ammo in it's magazine.

There are other ways to handle this that can certainly be a bit cleaner, but this should be fairly simple. The bonus is, it would be trivial to change the amount of weapons you can hold, you just increase the array.

Make sure too when you switch the weapons, you increment that current weapon index. That's how you track what weapon is being used. Otherwise, you'd just switch weapon to the same weapon.

Then, if you are at the final element in the array, wrap back around to 0. For 2 weapons it would result in Primary -> Secondary -> Primary -> Secondary -> etc...
For 3, it would be Primary -> Secondary -> Tertiary -> Primary -> Secondary....

[maiden wadi]

You usually need to sample a texture.

[thin panther]

As for the pickups, they can simply be a mesh and a weapon struct. Find an MP5 on the floor, it's not actually the MP5 you would shoot, but instead the MP5 mesh that has a struct that says "Weapon Class: MP5, Current Ammo: 12, Ammo In Reserves: 120". The actual MP5 weapon can then track the constant data, like "Max Ammo In Mag", and when you shoot, you take the current ammo in the weapon struct down by 1. When you reload, Ammo In Reserves becomes (Ammo In Reserves - (Max Ammo In Mag - Current Ammo)), current ammo shoots up to Max Ammo In Mag. When you drop the weapon, it simply spawns a new Pickup actor with the mesh of the weapon, and it's current weapon struct, then destroys itself and sets that index to empty.

[olive yarrow]

I love you.

I'ma read, attempt and update ya. I've got m struct set up and it added as an array variable in the player so far

[thin panther]

Sounds like a plan. There's a bit of implementation I've left out for you ti figure, but I have confidence youi'll manage. Ping me if you get stuck and, time allowing, I'll help out

[heavy lion]

So, I have an interaction trace which sets an actor as the "LookAtActor" variable.
Then I have an Input which calls Interact from the blueprint interface.
The bed actor I am looking at works, The door I look at works.
But I want to move the functionality of the bed to the player controller.

How do I let the player controller know its a bed they are using without casting?

Do I add a new interface to that bed actor and check if inherits "bed" interface. Or can I reuse the Interact Interface?

[olive yarrow]

I haven't gotten any further. after applying the start i'm not really sure what to do with it

[thin panther]

Might be an idea to start with your pickup actors and weapons, so there's something to pickup and shoot

Make some pickup actors, give them some meshes to represent their weapons, and a weapon struct that you can fill out.

[olive yarrow]

I've gotten weapons and their pickup variants made - with the weapons able to shoot reload yadda yadda

But currently i'm storing all this with bools

though not a weapon struct in them!

[thin panther]

lets start by revisiting the requirements.
We need:

• A pickup actor. This contains the information that needs to be transferred to the inventory, as well as it's visual mesh in the world.
• The weapon that can shoot. This contains the static information of the weapon that will be the same every time it's respawned. It also contains the stuff you need to shoot the weapon. It should also contain the modifiable data, like the current ammo and the ammo in reserves, which is initialised on spawning via the weapon struct, and copied back when switching.
• The player to hold an array of weapons. The amount of entries in the array should be the number of weapons that we can equip at once.
• The player to track the currently equipped weapon. This should be a reference to the currently spawned actor, so we can do things like call shoot on it, as well as retrieve the ammo information from before we destroy it and switch weapons. It should also be a index, to know which element of the array is our "equipped" weapon.
• The player to be able to switch weapons. This should involve taking the current equipped weapon, copying the current ammo and max ammo back into the weapon struct, destroying the current equipped weapon, then incrementing the current equipped weapon index, or subtracting it if you want to be able to do a "scroll up to switch up, scroll down to switch down" type thing. You should then be checking that this index is not greater or smaller than the array. If it's greater, snap back to 0, otherwise if it's less than, snap back to the last array index. Then we should spawn the new weapon, and initialise it's current ammo and max ammo, from the information in the struct

[olive yarrow]

moments being a visual learner ruin your day

[lunar sleet]

Hold on while we make you a YT video lol

[thin panther]

Another thing worth a look if you plan on using a fair few weapons would be to look into Soft References

[olive yarrow]

Do i have time to grab some lunch?\

[heavy lion]

This "works", I am wondering if there is a better way to implement this. Maybe in one interface? Maybe using tags?

[lunar sleet]

I’d say you have all the time in the world

[lunar sleet]

Yes

If the actor doesn’t implement the interface it’ll just fail silently

So no reason for the check

[thin panther]

This kinda defeats the point of an interface. An interface is for applying general functionality across a range of objects.

Instead, have a general interact interface. The bed might implement this interface to sleep. A chest of drawers might implement it to open. A door might implement it to open.

If you were going to do it this way, you might as well cast

[lunar sleet]

Aye, the bed’s Interact function should make it Activate the Bed

Your player doesn’t need to know about it

[heavy lion]

But then I am casting from the bed again which is what I want to avoid.

[thin panther]

but you're not fixing anything doing it this way, you're just reinventing casting but worse

How would the player controller know they are interacting with a bed or a door?

[thin panther]

they shouldn't care

an interaction is the same either way

[lunar sleet]

Because the bed and the door have different functionality

[thin panther]

The object itself handles the difference

To a player controller you don't care what it is, you just wanna interact

[lunar sleet]

Your goal should be to just call the logic, regardless of what is under the hood

[thin panther]

The bed cares about being a bed

[heavy lion]

The player controller has functionality which determins how long they should sleep for. It uses the player stats and the bed stats to determine this value, with some randomness applied.

[thin panther]

the bed can do that though

the player controller shouldn't care

[heavy lion]

But then I have to cast to the player controller

[thin panther]

from the bed, which doesn't matter

the bed should handle it's own sleeping using the information it needs from wherever

then you get to use the same interface to interact with a door, pickup a gun, launch a space shuttle to mars, etc.

The AI red panda is right - doing the same thing currently myself. Although in C++, I use an interface to implement an interact function, which is called when the player presses a key while its line trace detects something. Then each interactable implements the interface and handles its own logic in the function. Ie doors, elevators, picking up items, etc

[thin panther]

at least someone got the animal right this time 🥲

[trim matrix]

Couldn’t mistake an animal that cute

[heavy lion]

So using a single interface for interaction is more important than reducing casts?

[thin panther]

reducing casts isn't that important

[heavy lion]

I thought the point of interfaces was to reduce casting

[thin panther]

no

the point of interfaces is to apply behaviours across things that otherwise share no similarity

I.e. invoke behaviour when you don't care about the type of the thing that's doing it

[heavy lion]

Well.

Time to undo 😆

Wait, what if I can have multiple characters interact. Say an NPC and or player

The behaviour will differ

[thin panther]

Well you could pass in information based on what's interacting, or handle two different interfaces

Why is the playercontroller handling what happens when a bed is interacted with tho ?

encapsulate the logic where it belongs

It's ok for the bed to know about the character

character doesnt need to know about the bed , specifically

casting is fine when the interacting class is guaranteed to be loaded (not much of a game without a player character ?)

In such a scenario as the Bed I'd consider letting the bed take temporary control over the interacting Actor (PlayerCharacter) and controlling it's behaviour for a limited period of time. During this time the bed would have some timer or whatever, using its internally known comfort level to increase the Energy level of the PlayerCharacter

Cancel Drag & Drop still crashes editor after 4 years, whyyyyyyyyyyy

[gentle urchin]

mine doesn't 😮

[queen valley]

wait rly?

my editor just freezes after cancel drag drop

[gentle urchin]

editor, as in when played in editor (PIE) ?

[queen valley]

Yea, but the game doesn't just stop with errors, the whole editor crashes

[gentle urchin]

gotta test to verify now, so i dont spread lies without verification lol

[queen valley]

I saw people talking about this around 4 years ago

and it still happens

for me at least

k

[gentle urchin]

are you doing anything special while canceling ?

[queen valley]

nope, I detect if drag left the widget and then cancel it

[gentle urchin]

as in you call Cancel Drag & Drop, right?

[gentle urchin]

yeah im not sure i actually call that

[queen valley]

what do you do then?

[gentle urchin]

just leave the drop unhandled

so it returns here

[queen valley]

i need to cancel it cause if I close my inventory (remove widget) the drag and drop image stays on screen with cursor

[queen valley]

does it crash for you if you call this?

[gentle urchin]

Hm I did encounter a crash actually

right about here

[queen valley]

I can't believe something as simple as this still isn't fixed

[gentle urchin]

and now i seem to get your crash

OwningWidget seem to be not here

[heavy lion]

This is what I always assume is the case. But everything online is like "DONT EVER CAST!"

[gentle urchin]

ignore that

[gentle urchin]

apparently not big enough for it to be worth fixing

so it seems its not an issue many have
