blueprint

[trim matrix]

thank you!

[mental trellis]

If only they were still called that in cpp. 😦

[odd ember]

they are in HLSL!

[odd veldt]

but not with standard static meshes?

wantet to use primitive data on the meshes

[sharp fox]

anyone know how do i start moving immideatlly not smooth (sorry for bad english)

[plain helm]

Is there a way to show HUD smoothly when players starts to fight enemy and hide when fighting is done?

[odd veldt]

turn up acceleration to a high number

[sharp fox]

ui animations

[plain helm]

Other than Create Widget node

[sharp fox]

i know but i don't wont to be that when im in air

[plain helm]

Create Widget node make it appear instantly

Like in God of War 4

[sharp fox]

ui animations

create animation and change opacity

[sharp fox]

.

[plain helm]

Thank you

[hollow gorge]

when I'm trying to delete a blueprint(1), it tells me there are still remaining references in another blueprint(2), however blueprint(2) is totally empty. Is there a way to see the reference that's being mentioned when deleting?

as in a way to jump to the supposed location / node

[sharp fox]

did you save blueprint(2)?

and compile?

[hollow gorge]

compiled, saved and restarted editor. Same issue. There's no shared functions or interfaces remaining either

it should be a literally empty blueprint at this point

[sharp fox]

try maybe cleaning cache

[trim matrix]

can we execute console commands in production?

[sharp fox]

what do you mean by production

[trim matrix]

in a production package

not a debug

[sharp fox]

i think yea

i used to do execute console command when i was making options menu

anyone know how i can clean up this mess?

[mellow folio]

that's pretty low resolution...

but it doesn't look that messy, looks like a standard movement logic graph

[gentle urchin]

move things to functions , cleans it up instantly 😄

[sharp fox]

Thank you 😄

[sharp fox]

Because it is

[trim matrix]

Hi everyone! do you know where i can find a brickwall generator ?

[odd ember]

what is a brickwall generator?

[icy dragon]

Contact your local masonry

[trim matrix]

https://www.unrealengine.com/marketplace/en-US/product/3d-brick-builder-blueprint#

like this

but this one is not available yet

[odd ember]

well I would say here: https://www.unrealengine.com/marketplace/en-US/product/3d-brick-builder-blueprint

but it's not available

[trim matrix]

yeah...

well i'm trying to re-create a basic one... but i can have column x-y properly, but having issue adding the Y component...

[odd ember]

anyway this is a tech art tool. if you have the other assets you can make the functionality yourself

but it's not going to be cheap

[trim matrix]

i'm doing like thie

it's working fine if i have a basic grid X-Y

but not sure how to add a Z column, to be able to do tower of bricks

[odd ember]

isn't that just using multiple instances?

of the 2d version, that is

[trim matrix]

yeah

[odd ember]

so what's the problem with doing that?

[trim matrix]

well the

well i can't get a column of sphere

instead it does like a stair shape

[odd ember]

set whichever axis it does stairs on to be 0

[trim matrix]

i would need something more like this

[odd ember]

for that you'd need to do pretty complex math to get the patterns right

not sure why you wouldn't just use a material at that point

[trim matrix]

ok... let me see

[gentle urchin]

Isnt column laregly a top and bottom with an extra row/column ?

while the middle sections dont ?

seen from 2d it would be
ccccc
ccc
ccc
ccc
ccccc

[trim matrix]

yes

i would need even simpler

like

[gentle urchin]

So division reminder

[trim matrix]

ccc
ccc
ccc
ccc
ccc

[gentle urchin]

would get you started

[trim matrix]

so modulo?

[gentle urchin]

yeah

[trim matrix]

ok

[trim matrix]

WHAAAT

wheredi you find that?

[gentle urchin]

i made it

[trim matrix]

legend!

may i steal your BP nodes?

:p

or may i have a sneak pick of it?

[gentle urchin]

this is assuming uniform bricks

[trim matrix]

you rock

let me steal from you

thank you Squize

[gentle urchin]

Top or bot would be the Z layer = 0 or > Max - Z divisor

[trim matrix]

trying !

[gentle urchin]

Its getting messy here

but the walls

[ancient sparrow]

Is it possible for me to make a camera's clip plane visible for testing purposes?

[trim matrix]

love it

[gentle urchin]

having these one could add random destruction to them if you want some diversity

[gentle urchin]

removing a brick here and there

[trim matrix]

i might have miss something lol.

[gentle urchin]

not distributing X/Y properly it seem

[trim matrix]

what are X Y Z variable?

[gentle urchin]

grid locations /layers

X is Row, Y is column, Z is layer

[trim matrix]

ohh ok adjusting 🙂

[mental trellis]

There's an absolutely amazing plugin that does this sort of stuff. Shame I can't remember the name of it...

[trim matrix]

doing exactly like you

[thin panther]

Is it that proinstance or smthn like that

[mental trellis]

I honestly don't know. I don't even know if it's public 😄

[trim matrix]

oops found some issues

adjusting 🙂

working!! thank you @gentle urchin

[odd ember]

looks more like noisy than that from the image. like you would have

icci
 ci
 ic
 ci
 ic
icci```

[gentle urchin]

Agreed , was just to get them started

[odd ember]

and that's just for a column with 2 bricks per row

[trim matrix]

yes actually just saw that, does not work if i had more than 2 columns

2x2

[gentle urchin]

Mine works for any number of xyz

[trim matrix]

oh

does it has to be X = Y ?

everyti,e

[gentle urchin]

You got modulo all over the place it seem

I got modulo and division

X != Y

[trim matrix]

yes 🙂 i did adjusted it.. but seems to work if X and Y are equals here, which is not bad

[gentle urchin]

Then you got it wrong^^

[trim matrix]

oh oh

maybe because i'm not using the last index setup you have as i had to connect the one from the one i had.. 😦

[analog hazel]

some one messaged me yesterday about my camera issue but cant find it in the older messages...

[gentle urchin]

4x3x5

4x8x10

Not sure i'd call this clean by any measure but it's what i had time for @trim matrix

[trim matrix]

Legend !! Having a deep look!!

[analog hazel]

Yeah im unsucessfull with my camera guys...

[icy dragon]

Maybe being a cameraman is not the right gig

[analog hazel]

nah, my camera BP is what im having issues with still....

[plain helm]

https://youtu.be/vDBokIaxLM0

How to make animation hitstop like in the video?

[covert sparrow]

hey guys am i be able to run a custom event in persistant level from widget blueprint ?

[icy dragon]

As in the custom event situated in Level BP?

[covert sparrow]

yea, is it possible to use something like remote event for that in WB ?

[icy dragon]

Ouch, avoid doing that.

Level BP stuff is much more difficult to access from elsewhere.

[analog hazel]

So guys... With this move forward mapping, I need my camera to reset back behind the pawn.... And im having very hard time figureing this out...

[restive oracle]

Anyone know why my widget component isn't visible?

[icy dragon]

Also (my own) general rule of thumb is that widgets should do as less work as possible for actors.

[covert sparrow]

ah 😦 i just wanted to unload a level before loading another in visible but if i do that in the same level i am loading from, the next code won't run doe to current unloaded level

doesn't work like that

[covert sparrow]

mm, thanks for your answer

[restive oracle]

Ooops, it was rendering, it seems the widget was one sided lol

[trim matrix]

guys, do you know how to get back the defaultSceneRoot in a blueprint?

i "removed" it by mystake

[gentle urchin]

Ctrl + Z

Saves the day

[trim matrix]

well... i did it 2 days ago..

if i create a scene component could it do the trick?

[odd ember]

yeah it's just a scene component

[icy dragon]

Or just make a SceneComponent and make it a new root

[odd ember]

but you won't be able to get the white circle back

[trim matrix]

awesome, thank you guys!

[icy dragon]

DefaultSceneRoot is nothing but Scene Component, just with different name

[odd ember]

well technically

it's a billboard component masquerading

that's why you get the white circle

[summer jetty]

I have a question about reading/writing to savegame data files if anyone can help?

I'm using a savegame file to store data in the game that needs to be saved between levels and after closing the game. There are 3 game slots that can each have a character saved to them. When the player picks/creates a character via the start menu widget, it updates an 'ActiveSlot' variable in the savegame file to the slot number (1-3). I think that part is working ok.

However, during the game various level maps/widgets need to read/write to the savegame file and obviously it should only be the active slot being played. So first I have the event (for example, clicking a button on an NPC dialogue to accept an invitation to join a Guild A) do LoadGamefromSlot by getting the value of variable 'ActiveSlot' from the SaveGame_Custom file (where the data is stored). Then CastToSaveGame_Custom and set the variable 'Guild' to A. However, it's asking for a Target when I tell it to get the ActiveSlot value. I'm guessing this is because I need to save the ActiveSlot value somewhere outside of the SaveGame file during the game in order to use that value to read the correct GameSlot in the first place? Or am I just misunderstanding how loading/casting to game slots works?

[odd ember]

you can't write to save files in BP

your save data is stored inside the project's own binaries

[analog hazel]

OHHHH i Almost got it actually... but one other thing is... my camera ref I have set behind the camera, is actually making it look completely top down on the reset

[summer jetty]

Really? How do you save/update data between levels/games?

[odd ember]

use the provided nodes. save files means you would have to save to disk, which isn't exposed in BP

(for good reason)

[analog hazel]

with my camera reset being an arrow on my character for the reference its taking my camera all the way up and pointing straight down, which is not the correct location

[summer jetty]

'provided nodes' - sorry, what do you mean by that specifically?

[gentle urchin]

The bp exposed save functions

[odd ember]

the ones you mentioned

[gentle urchin]

SaveToSlot, DoesSlotExist, LoadFromSlot etc

[worn galleon]

why i can not set projectile movement gravity scale in rutime ? after my collision begin overlap ? i want set projectile movement gravity equal 0 , but not apply

[analog hazel]

any help guys? i almost got it working...

[summer jetty]

Ok, that's what I mean by 'savegame' files. I thought save game files were like the template (which variables to include) and then Slot1, Slot2, etc were versions of it where the data is?

So I don't need to Cast to SaveGame_Custom. I can just Cast to Slot1, Slot2, etc?

[odd ember]

slot is the location

[summer jetty]

And read/write the date from there

[odd ember]

but ideally you should just have one custom save game class

[summer jetty]

I have others with just fixed (read only) data for things like item info, etc. But only one that is character specific and needs to update the variable values in the slot.

[odd ember]

well you can't cast to the slot

the slot isn't a "thing", it's a location

[summer jetty]

so whenever I need a On Clicked event to read/write to the variables in the slot, I can just Load Game from Slot x and Get or Set the variable?

[odd ember]

no, you'd need to cast

[summer jetty]

You said I can't cast to the slot? I'm confused

: /

[odd ember]

you can't cast to the slot, but you can cast the object that exists in the slot

the slot is like a pocket. it's not really anything, but you can put something into a pocket

and you can take something out of the pocket

[analog hazel]

please guys my code working now but my camera reset reference in the character PB is pointing it straight down for some reason? but its same location as the camera and direction...

[odd ember]

#rules #2

[summer jetty]

So OnClicked(button name) > LoadGameFromSlotx > Cast To Variable n > Set Variable n to (whatever new value)

[odd ember]

cast to <your save game object>

then get <your variable name>

[analog hazel]

rule 2 got it

[summer jetty]

Ok, that's what I was doing originally. I have OnClicked(button name) > LoadGameFromSlotx > Cast To SaveGame_Custom (which is the name of my savegame file) > Set Variable n to (whatever new value)

By 'file' I mean the name of the blueprint file in the Unreal Editor

But I need to get the Slot Name to load from the ActiveSlot value that's stored in the slot

So I'm guessing I need to store the ActiveSlot variable somewhere else that I can pull from?

[odd ember]

you'd typically have a manager class that handles this

[summer jetty]

I can't just save it somewhere like the thirdpersoncharacter blueprint during the game?

[odd ember]

you can technically do it anywhere, but keep in mind that for it to load, whatever the manager class is, it has to be loaded. so if you handle it in the player, then the character has to be loaded. this would also means for menus etc. the character would have to be loaded then

you could try perhaps handling it in the player controller

or in the game mode

[summer jetty]

ok, I'll try that

thank you! 😄

[analog hazel]

ill try back tomorrow... sorry guys for breaking rule 2

[gentle urchin]

Did you post any code ?

What exactly is the issue?

[analog hazel]

I got my code working way Id like at the moment but the camera reset position isnt working as intended....

I have the camera reset position reference where the arrow is but its not going back to that, its going way up high and pointing my camera straight down...

[gentle urchin]

Arrow is following camera

So

Its not gonna stay put

[analog hazel]

Is the code....

Moved it to the mesh which fixed that thank you, Still a Snap which timeline isnt helping much..

[gentle urchin]

Thats a code issue

[analog hazel]

Yeah... I cant find it though..

[gentle urchin]

Using a manager might make this... less messy?

Where you could expose your own functionality for setting a new view location for the camera

[analog hazel]

I tried camera manager couldnt get it to work probably wasnt just coding it right though

camera manager - root component get world rotation is doing same thing, takes it way up and points it straight down.... Thank you for giving me a hand...

[mental robin]

Crashes every time I try to remove the instance. Here's what confuses the living balls out of me...the instance is valid...it exists at that index..but yet removing it crashes. What could be wrong I do not know

[spark steppe]

show how you get the index (also it would be nice if the screenshot was better readable, try to not zoom out that much)

[fervent raft]

how can i rotate a socket

for bones there is transform modify bone

[spark steppe]

should be the same for sockets?

or doesn't the socket show up in the list?

[fervent raft]

it doesnt show

[mental robin]

But I am doing the valid check and it passes true....if it wasnt there then why would it crash it doesnt make sense

[fervent raft]

theres this but it doesnt seem right

must be something else

[mental robin]

ive literally neevr had a problem removing an instance before because I always always check for it to exist

[fervent raft]

@spark steppe I think I need to rotate the mesh attached to the socket in case you were wondering

Seems to work

[mental robin]

It turns out it was ADDING an instance mesh in its place after was causing the issue

[molten yew]

hey how can I simplify this blueprint code?

[slow pewter]

I would remove all Get All Actors of Class, because thats Expensive.

[summer jetty]

@odd ember (or anyone else that can help). I tried adding the variable ActiveSlot to the game mode. But I'm now getting new error messages when I try to reference this.

[thin panther]

You need to create a save game object

Oh wait

For the gamemode

Get gamemode

?

[spark steppe]

make an foreach array that iterates over a classes array, and make a static array which holds the 3 classes

[molten yew]

@spark steppe I attempted to do that but I can't connect the "add impulse" to it

[analog hazel]

@gentle urchin I cleaned up my code if your interested in checking it out. its now on the Tick event though.

[summer jetty]

When I create a character it should update the ActiveSlot variable in game mode, but it doesn't like that. Then the second part should read the ActiveSlot variable in game mode and use this value to update a different value in that game slot.

[thin panther]

Yeah

Ik

So do what i said

Youre casting with no object

[summer jetty]

In the first blueprint?

[thin panther]

And in the second screenshot you are getting a variable from another claaa without specifyong the object

Yes

[summer jetty]

ah ok

[thin panther]

And you still need to hook up your reference in screenshot no. 2

Cause you havent got a target there

[summer jetty]

ok, tat fixed the first bluprint

[mental robin]

I keep getting this error if (!ensure(RenderInstanceIndex < NumRenderInstances)) ..I just dont get it..I have significantly more complicated blueprints involving instances that is replicated as well that works fine..why this is giving me treouble for something so simple

[thin panther]

So either save the result of that cast into a var, or cast again, before your active slot in sc no 2

[thin panther]

It seems like youre trying to access an invalid index? Maybe post a screenshot of the error and some code

[tight pollen]

I use SphereTraceByCannel to pick up items and for each item I added a SphereCollision. I would like SphereTraceByChanel to have Overlaping with this SphereCollision, How can I do that in addition to an Item that is set to Block for Interaction, i would like also causes overlaping for the collision that is attached to the item (SphereCollision)

sorry for english

I don't know if I wrote it right

[thin panther]

Why not just monitor if you overlap the sphere collision

[summer jetty]

hang on, shouldn't that just let me connect get game mode as the reference too?

[thin panther]

Rather than sphere tracing

[thin panther]

Might do, might not

[summer jetty]

ok, it doesn't : /

[thin panther]

Depends if it returns a general game mode ref or a specific one

Ok so do the cast

[tight pollen]

how

[thin panther]

On component begin overlap event

You havent explained well

What ur tryina do

Why do you use a sphere trace

[tight pollen]

Sphere trace is for Looking for Item

when Character look at item show Interaction Widget

[thin panther]

Ok

[tight pollen]

i add also SphereCollision to Items

with i want Overlaping this SphereTraceByChannel

Items is set to Blocking SphereTraceByChannel, but SphereCollision is set to Overlaping SphereTraceByChannel

Item is in SphereCollision

I do not know if you understand me 😅

[thin panther]

So you only want the sphere collision to interact with trace, and not the player

[tight pollen]

I only want the sphere collision to Overlap with SphereTraceByChannel

SphereCollision - which is in the item

[thin panther]

Yeah so what i said

So set the sphere collisions collision to block whichever trace channel you are using, probably visibility, and overlap the rest

[tight pollen]

and the other way around?

[weak widget]

If I have these two UFunctions in the C++ code for my first person character (the default template that i've modified), how can I access them from a blueprint?

[thin panther]

?

[thin panther]

BlueprintCallable

Also a question for cpp

But stick BlueprintCallable in that UFUNCTION

[kind estuary]

Im creating instances of static mesh using Add Instance. But then after, i need to move some of these instances. When i use static mesh i just add a tag to them, and get them by that tag. But using add instance doesn't allow me to add tags to the instances. So how do i access them?
Is there something like "get all instanced static meshes" inside blueprint?

[weak widget]

Alright

[tight pollen]

sphere collison - Overlap ///// Item - Block

In break HitResult is some Initial Overlap

but nothing happen, although I set SphereCollision which is in Item to Overlap

[weak widget]

Then this is how I would get that function in a blueprint right?

[thin panther]

I have no idea what you mean

[thin panther]

Wouldnt you cast to the c++ class you made

[tight pollen]

I'll draw it for you
😅

[thin panther]

First person character is a different class

Unless that inherits from firstpersoncharacyer

[proper veldt]

have everyone,
i want to test the actor sequence component, but cant find it in plugin list
maybe someone could help me find it?

[hazy sandal]

Do u guys KNow how to apply camera shake? Ive tried several ways, and it works only if the camera shake duration ist set greate than 0.

Is there a trick to it?

[summer jetty]

@thin panther ok, so I played around with what you suggested. Now have different error messages (which is progress). Created a variable in the blueprint called ActiveSlot so I can get the value from Game Mode and copy it to that. Then use the blueprint variable value to plug into the SlotName. It doesn't let me connect 'Get ActiveSlot' (from GameMode) directly into the CastToGameMode, so tried connecting it to the Set blueprint version of the variable. But doesn't like that either.

[tight pollen]

@thin panther

how can i achieve it? 😄

SphereTraceByChannel Blocking Item but not overlaping SphereCollision

[thin panther]

Whats the point in the sphere if its just overlapping

[trim matrix]

are you watching the keynote?

[thin panther]

Cast to the game mode youre using not the base class, you want the third person gamemode and then to hook that into your target

[tight pollen]

I want an additional widget to be displayed when Overlap with SphereCollision occurs

[summer jetty]

@thin panther It has 4 options to cast to: Game Mode, Game Mode Class, Game Mode Base, Game Mode Base Class. I chose just Game Mode. I'm not using any custom Game Mode, so not sure what else it would be?

[thin panther]

Oh ok, so set sphere to overlap all, and item to block all

Then for your widget just monitor when the player overlaps the sphere

[thin panther]

You are, you have ThirdPersonGameMode right in the bp above

[summer jetty]

aaaaah ok, that didn't show in the list. Ok, I'll reconnect everything to that and try again

@thin panther ok, that's working perfectly now!! Thank you so much for your help. That's been driving me nuts for days! 🍻

[thin panther]

No problem :)

[analog hazel]

Hey so got a mouse question.... How to detect if mouse move on the screen?

[hollow gorge]

maybe this?

[brazen pike]

Myabe just store the position of the mouse on tick and if the last position is different to the current position then it is moving

[analog hazel]

how would i do that? i got my character rotation on a mouse button but it rotates automatically on mouse down vs mouse down + movement if that makes since

[brazen pike]

Not sure what you mean but I'm fairly sure this type of thing would work:

[analog hazel]

oh that might do it let me try that

Trying to add something like that to that branch so like when I Click it dont set right away till their is some movement

[peak summit]

What could be used at runtime to create a temporary pothole in a terrain?

[brazen pike]

so where are you setting it?

[analog hazel]

The mouse? its my rotation movement to my character

[brazen pike]

No i mean mouse position

[analog hazel]

It just need detected that its Moving not really needs set but probably not bad to set it also, may break something down the road, its not being set no where at the moment

[brazen pike]

Yeah as it is now, it will always be true if the mouse is not at 0,0

which is majority of the time

and even when not moving, although you seem to only be firing it off when it is moving since you're doing through the character

which means you probably wouldn't need the code I suggested

[analog hazel]

Okay, yeah its on my controller, I use the mouse for rotation, movement, and interaction

Is that something I should put on the Tick node since im doing so much with the mouse location/rotation?

[ashen snow]

How does one get text floating over actors in the editor - not in game

I'm trying to make editor utility widget that can help me keep track of curves that are created with each entry to an array. But it's hard to know which one is which when it's just an array

They have names and I would like to print those names on top of the actor in the editor window

[trim matrix]

So since nativization is gone now is Blueprint faster in ue5 ?

[brazen pike]

Personally, I'd leave it on the turn event since I was assuming that you were moving the mouse on a widget or something and wouldn't have any specific event that fires off only when moving the mouse.

At which point I'd recommend putting it on tick which sets a boolean, but since that isn't the case just keep it on the turn event

[peak summit]

are landscape splines not accessible via BP?

[analog hazel]

Thank you ill check out the turn event

[analog hazel]

This is what I did, Get viewport size divided by 2 for setmouseposition node hooked up to mouse release, so when im done with mouse down it resets to middle of my screen works great for mouse reset

[brazen pike]

Is that what you wanted to achieve? I could have suggested that from the beginning haha

[analog hazel]

Its an improvement but not really what im after.... Still need to detect when mouse moves before the set control rotation accurse

If you look at the code, everything on the Seq sets the rotation with that mouse button down... but it sets before mouse movement is detected

[zealous fog]

Any BP improvements in UE5?

[native willow]

no, they are still poorly implemented

[faint pasture]

What's your suggestion to make them better?

[native willow]

first suggestion, stop copying literally everything, even if you take smth as a reference, it will get copied, not only it wastes time but also memory

[faint pasture]

Copying only matters if it's above 64 bits, and I doubt there's much being copied around that's over that size.

[ashen snow]

Anyone know how I can get selected components? I see in my utility BP that I can Get selected actor - but nowhere do I see how to get selected component

[mild pine]

Hey guys, I'm trying to make a gas cloud that originates in one position, and over time spreads in all directions, clamping at X distance. What's important is that this gas is supposed to hurt the player - does anyone have any tips or learning resources in order to make that system?

[faint pasture]

Depends on the context, do you already have some sort of grid?

does it have to collide or pass through walls

etc etc

[native willow]

it matters, when its heap memory, heap memory allocation is actually quite slow so copying an array with every function call actually slows down the system

[mild pine]

No grid. I might have to set one up though, as I want to arrange for multiple kinds of events like this. Fire propagation down the road, etc. Not sure how well that handles in a multiplayer setting, but yeah

[native willow]

also, literally almost every struct, and every array will get copied

[mild pine]

Oh it can pass through walls as long as it's within the X distance (sorry for the double ping)

[faint pasture]

TArrays are passed around by pointers my man

[native willow]

it is true, but it is only the case for c++, blueprints will copy it anyway

thats my case, that reference thing in blueprints is just fake, copy will still be done

[faint pasture]

I await your PR with bated breath.

[native willow]

there are tons of them, ignored by epic

[faint pasture]

If you can just ignore all collisions then just expand some collider and call it a day.

[native willow]

for years

[faint pasture]

If it must respect walls and flow around things, that'll be 100x more complicated

[native willow]

just visit their github mate

[faint pasture]

I'm on the github, can't find shit about this.

[mild pine]

Wow, why didn't I think of that 🤦 Game dev requires such a creative "out of the box" mindset 😆
If I expand a sphere for the collision to ensure damage, how should I best go about spawning the particles? They wouldn't look too great if I just scaled them, talking about a big area 🙂
Maybe spawning X amount of particles along preset locations on the sphere every X time?

[faint pasture]

Make a particle system that spawns particles in a box

or a sphere

with a changable radius

[mild pine]

Oh, and the size of the sphere would be a variable driving the size of the particle's bounds aswell?

[native willow]

big fixes

[faint pasture]

Well yeah there's a lot, where's the one about this BP copy stuff?

[faint pasture]

Yes either sphere radius or box dimensions or whatever

[native willow]

why are you so aggresive to me?

what have I done to you?

[faint pasture]

I want to see an actual PR describing this problem, you said there's tons of them, can't find them.

[thin panther]

agressive?

theres no agression here

[native willow]

I showed you, 434 bug fix PRs ignored for more then 8 years

[thin panther]

but the point is none of them state this specific issue

[native willow]

improving blueprint system would require complately redesigning the system

im not up for that

[thin panther]

the point is you have yet to back up your claims

[unkempt terrace]

hey guys, any idea why this warning occurs ? cant find a single post about it anywhere:
LogLevel: Warning: Missing actor folder for actor StaticMeshActor_307_GEN_VARIABLE_StaticMeshActor_CAT_UAID_A4BB6DCD1023EF0101_1317213324
it happens on many staticmeshes of a blueprint and seem to cause the app to crash after some time

[native willow]

I dont need to backup anything, the copy thing is a fact, literally put a breakpoint in a copy constructor of TArray object and you'll see

and the fact that you Adriel are saying that I should submit a PR fixing that is a nonsense, someone asked about it so I answered, dont need to be so aggressive about the facts

[thin panther]

no ones being agressive

and we arent sying you should submit one

we are saying we want evidence the problem exists

[native willow]

literally read what Adriel said

[thin panther]

idk what im doing in source code, so it would be nice to see

[peak summit]

this always returns Default even if i set all my layer infos i paint on my terrain with a physical mat that has the surface type set to something else.. any ideas?

[faint pasture]

You guys are funny. I just wanna see a PR about this, you said there were a few already. Not being aggressive, just wanna see one and maybe implement it on my end.

[thin panther]

exactly i just wanna see the evidence behind the claims so i can go about fixing it

im not about to uproot my entire project if there isnt any evidence towards it

[native willow]

you wont see it, epic is already going into Verse, so new blueprint system will not come anytime soon

[native willow]

#blueprint message

[native willow]

good luck, blueprint system is actually really huge, there is a lot of stuff from kismet that havent been refactored

[thin panther]

i dont mean fixing the entire bp system lol

waaay outta my scope

[native willow]

funny thing is that all of the custom blueprint node classes start with the K2_ which is a convention coming from kismet

[thin panther]

i mean translating whatever i need into c++

[native willow]

fixing that copy thing would require you to do so

and that is something that Adriel is expecting from me for some reason

which is funny

[thin panther]

.

[native willow]

not talking about you specifically

its more to explain what Adriel is expecting

[summer jetty]

@thin panther I lied. It almost works, but not quite! Failing to cast to the SaveGame_Custom bit. Tried casting to a basic SaveGame, but that didn't make any difference.

[thin panther]

then it seems an issue with that active slot

[faint pasture]

Did you save a game to that slot with your custom savegame class prior to this?

[thin panther]

are you sure you have a save game in that slot

[summer jetty]

it should create one when I click on create character (the screen before the above one). The only way it would fail to create one is if all three slots are already taken.

So either way there would be an active slot chosen

[faint pasture]

Show where you save the game to the slot

[maiden wadi]

Have never once had that fail with a correct string input. If it's not loading the savegame, it definitely doesn't exist. So either your creation failed for some reason, or you didn't save it after creating it.

[summer jetty]

ok 2 mins...

[maiden wadi]

Where is it being saved though?

[summer jetty]

SaveGame_Custom I thought? (or one of the slots that uses that to be precise)

[maiden wadi]

Nothing here is saving it. You're creating a SaveGame object. But never serializing it to disk with SaveGameToSlot

A SaveGame object is just a basic object that holds data variables in memory, that won't actually serialize it.

[summer jetty]

oh hang on... that's at the end

ah my slot name is different to the slot #!!!

i think that's why

[summer jetty]

set this up over 7 months ago

[maiden wadi]

Yeah. 😄

[faint pasture]

Glad to be your rubber ducks

[summer jetty]

damn it!

😄

[faint pasture]

btw you can see the savegames

in file explorer

to check if anything funky is going on

[summer jetty]

yeah, they were showing up in my save game folder when i first tested it way back then

ok, I'll do the walk of shame back to my blueprints! thank you all 😄

[maiden wadi]

Time to go see how many bugs I can find in UE5.

[dawn echo]

Hello everyone! Is there a way to save the socket the actor is attached to? So when I saved the game I can "snap" the actors togehter?

[faint pasture]

Sure, your savegame would hold some list of actors, their attach parents, and the socket name they're attached at

[south pier]

I'm having trouble understanding why my interact key doesn't open a door inside of the BP for the door, but it works if I have it open a door inside of a level blueprint. So here is my door BP

This is my level blueprint

In the door BP, if I set it to open upon entering the collision component, it works fine

[thin panther]

you can only take input in possessed things

you'll need an enable input node in that door

[south pier]

like so? Cause that works now

[thin panther]

ye smthn like that, its not an ideal solution but it works

[south pier]

It just seems like a pain to create an animation for each door I need to open in the level blueprint

[mild pine]

Hey guys, yet another nooby question from me here 😆 How should I go about making the player Jump move slower than the character's sprinting speed? Right now I can jump along a path at the same speed as someone thats sprinting. Could do a delay reset, but would be more realistic making the jump lose part of its movement maybe. I want the player to keep his upwards velocity. 🤔

[faint pasture]

You talking jumping while sprinting or jumping then trying to move?

@south pier make an event Interact or better yet, an interface

[mild pine]

Jumping then sprinting - I mean, having the jump speed somewhat replicate the actual movement prior to jump is needed, but right now its at the point where you can spam jump and move as fast as if you were running.

[faint pasture]

The character calls Interact on the door

[faint pasture]

Have event landed drop the speed a bit

So you carry speed through the jump but lose some on landing

[south pier]

And then this?

[mild pine]

That sounds great, thanks! To the rescue once again haha! 🙏

[faint pasture]

@south pier how are you opening the door? Like does the player press an interact button or what

[south pier]

Yes. E to interact.

[faint pasture]

Ok so press R -> figure out what you're trying to interact with (line or sphere trace, whatever -> call InteractInterface.Interact on it.

The thing implements Interact interface and does whatever it does. A door opens, an item is picked up, an ally is revived, a button is pressed, whatever

[south pier]

I don't think I am doing this right.

[storm dove]

is there any speed improvement for blueprints in UE5?

[south pier]

It's not even recognizing that I am pressing E

Okay. I found my issue. Interface works. Thank you for your help!

[rose elbow]

anyone know what the issue is here?

[maiden wadi]

@rose elbow Dedicated Server cannot create Widgets.

[rose elbow]

oh, whats the fix then?

[maiden wadi]

Generally this is the reason you don't create widgets in gameplay classes. AHUD should be used, which only exists on clients.

[leaden meadow]

@rose elbow in what blueprint is this? Is it in the player character or the map?

[maiden wadi]

It's in the player controller.

[leaden meadow]

Put it on the player blueprint

[maiden wadi]

Don't put it in the character. Put it in AHUD. Don't spawn widgets from gameplay classes.

[leaden meadow]

for exmaple the "TopDownCharacter" or in your chase probally "FirstPersonCharacter"

[rose elbow]

what is AHUD?

[maiden wadi]

Look in your GameMode. Where you set your default controller/pawn/etc. There's a class for HUD

[mental trellis]

That's the way AHUD AHUD I like it, AHUD AHUD.

[maiden wadi]

You can create one same way as a custom Controller in the content browser. Named HUD in BP

Local version of the player controller spawns and maintains an AHUD actor for that controller's player. One AHUD per player per machine. In non coop, that means one AHUD instance per PC that isn't a Dedicated server. You can get the HUD instance via GetPlayerController->GetHUD

[rose elbow]

Yep that's done it, thanks alot!

don't think i'll be running it on a dedicated server anyway I just had that option selected but these seems a better way to do it anyway

[maiden wadi]

Yeah. You could have done a IsDedicatedServer->Not->Branch. But you'd be doing that anywhere you create UI. Better just to have the local client spawn their own UI in the HUD class.

[summer jetty]

Back again! The cast to SaveGame and save new variable now works (yay). And it's also creating a new saved game file in the Unreal folder when I log out (also yay).

However, I realised I need to have some sort of preventative measure to stop the player repeatedly clicking the button to keep assigning a new random value to the game slot.

So I've added a branch to check if the variable value is the default of 'None'. If it is, then it should let a randomly assigned value be saved over it. If it isn't 'None', then it means the player must have already clicked on the button and assigned a value and therefore nothing else should happen.

I thought I'd set it up ok, but it's just ignoring the branch and letting me click repeatedly to get new values. Is there anything obvious I'm doing wrong? The default value for that variable is definitely 'None'.

I have a variable in the blueprint that it should copy the game slot value to. It then compares this value to 'None'.

[dark crow]

Try checking against nothing instead of none

[summer jetty]

That says 'already assigned', even on the first go (when nothing has been assigned yet)

[dark crow]

Even if you delete None and leave it empty?

[summer jetty]

Yeah, I checked it against nothing at all (which returns as 'False', since it will be the default value of 'None' and not nothing at all).

[dark crow]

Then check what it's returning from the SaveGame

It doesn't randomly do it

[summer jetty]

it's returning 'None'

ok, so it's spitting out a random value when I click the button, but not actually saving that value to the game slot. : /

So it stays as None every time. Even though I'm telling it to Set that value to the variable in the SaveGame slot.

I can't see what I'm missing.

[granite stratus]

has anyone else tried to use float math in the 5.0 release yet, it doesn't work for me

[marble tusk]

You have to right click the wildcard pin and convert it to a float that way. At least that's how to get around it in P2

[icy dragon]

They broke floating point math ops since P2

[dark crow]

Do you actually save after?

[icy dragon]

Expect at least 5.1 for that to be fixed

[summer jetty]

what do you mean? sorry, I haven't used savegame stuff before

[dark crow]

Well, to actually save the value, you gotta save :D

[stray wren]

Hi! So I've create this enemy with a laser attack and I'm trying to add some sort of offset of the laser vector and move it horizontally with a timeline to create a "sweeping" effect. How should I go about that? Here's the pastebin for the enemy linetrace and attack as well: https://blueprintue.com/blueprint/mkov28cn/

[summer jetty]

Isn't that what 'Set' does? I thought SaveGameToSlot was just when you create a new one and save all the variables you want to use? I'm only changing one of those variables in the above blueprint. If I use SaveGameToSlot, won't it overwrite all the other variables that I haven't changed here?

[dark crow]

I don't remember exactly, but I think Load is just for loading the values

[granite stratus]

maybe choose a start and end point and lerp between them with a value from the timeline

[dark crow]

You still gotta save them to disk after setting iirc

[summer jetty]

ah ok, I'll give that a go

I don't have many values added yet, so if it wipes them all it's not a big deal

[dark crow]

Not sure if you can use the returning value from Load to Save it or you gotta Create Save Game Object again

Documenation is very lacking regarding it from what I remember

[stray wren]

okay cool I'll try that if i can figure it out lol still somewhat unfamiliar with blueprints

[dark crow]

So experiment with it

[summer jetty]

yeah, I couldn't find a definite answer in the bits I read/saw

will do

cheers!

[granite stratus]

something like this

[stray wren]

oh okay! thats easy enough thank you so much : ))

[granite stratus]

np

@stray wren an extra little tip that I do with setups like this is also to put the timeline duration to 1 and modify the play rate of the timeline so you can have a variable that sets how long the attack is

[coral lance]

I want to make a throwable bola and grapple hook with rope physics but I don't know where to start

[stray wren]

ahh okay and my basic understanding of that is just so you can more easily tweak the attack duration instead of editing the timeline?

[granite stratus]

yeah

and you can vary the time based on different instances of the character or things like that

[stray wren]

right okay like if its being combined with different attacks or whatever

[granite stratus]

works better if you just have a simple timing curve

[stray wren]

makes sense

[outer hedge]

any blueprints for sekiro/dark souls like combat?

[granite stratus]

whys it on tick if you only do it once

[unreal wing]

Hey guys I had a question if anyone could answer it for me that would be great.

Is there a way to prevent the camera to not move while jumping?

Ive seen this is some games that uses unreal. I didnt know if it was root motion or something else. Any ideas?

[thin panther]

i mean you could keep the z value constant on tick ig

[small halo]

so the condition is always being checked

and i fixed it dw

[granite stratus]

got it

[unreal wing]

maybe

[stray wren]

https://blueprintue.com/blueprint/8tcvvz2l/ this is what i've come up with, just trying to figure out how and where i need to connect everything up. i took off the play rate for the time being just until i can get the timeline to work as is

^^^^ also wondering what i should put for the return value on the lerp vector node

[granite stratus]

probably want to put it over here

and feed the output into your trace end

determine your start end positions before you get to this point

with what is hooked into there now

[stray wren]

ohhhh okay

lemme try that

[flat coral]

Is there any way I can make a scene component with no children visible in editor? I just wanna make sure scaling is moving it correctly

[undone surge]

is there a way here where i can make this FABRIK node only execute only if this branch condtion is true otherwise connect the animation directly

[granite stratus]

pass a boolean into the blend

"Alpha"

[undone surge]

@granite stratus blend is the FABRIK node right

just like the alpha pin

or will it be in the separate animations

[granite stratus]

yeah

if the alpha is set to 0 or false it won't apply that pose to your final pose

[undone surge]

aaah

ill try it thnx

[granite stratus]

np

[undone surge]

so the alpha value takes 0 and 1 ?

[granite stratus]

0 through 1 yeah

so you can do 0.5 for halfway between

[undone surge]

what would be the input of the branch node here be though

[granite stratus]

you can't do branches in the pose graph

[undone surge]

aoh

[granite stratus]

i dont know why it lets you even spawn one

[undone surge]

oh

[granite stratus]

you basically replace what would normally be branches with blends

[undone surge]

i did this fabrik thing to allign the left hand to gun but now it messes up the reload animation so i wanted it to use the fabrik if i wasnt relaoding and direct one if i was reloading @granite stratus

how could i get around this

[granite stratus]

in theory it shouldn't mess it up if the alpha is 0

so you should be able to just flip the bool on when you need the hand to stick and false when you dont want it

[faint pasture]

Reloading should be a montage playing in a slot (UpperBody)

[undone surge]

Thank you

[cobalt gulch]

hi guys

how can I find a specific word in a string variable?

[faint pasture]

What are you trying to do is what i'm wondering

[cobalt gulch]

Create a variable for the type of sight the player wants to use

So i can find what they selected and put it on screen

[faint pasture]

Yeah nah

don't do that

unless it's a typing game

[cobalt gulch]

How could i do it?

[faint pasture]

Use an Enum or Name or something of the sort.

[fallen glade]

UMG tab is a bit dead, if you have any experience with it could you have a look at this? #umg message

[cobalt gulch]

ok

[faint pasture]

@cobalt gulchDescribe the mechanic, what does the player do and what happens on the screen

[cobalt gulch]

They click one of several widget buttons to give them a specific sight on their hud

So I would need to somehow find the word "1.5x Sight" in the name variable

[faint pasture]

OK so make a ButtonWidget with a texture variable and text etc. The outer widget (Settings menu I guess) would have multiple of those buttonwidgets and when pressed, it can pass the texture to whoever needs it (Set ReticleTexture on PlayerController/Pawn or whatever)

[cobalt gulch]

Could I not just show the specific widget element

I think it would be better because it's in a specific place

I just don't know how to find the words within the name variables

[faint pasture]

don't do that

They have some menu to pick their crosshair right?

[cobalt gulch]

yea

[faint pasture]

ok so that menu contains a few buttons that hold the different crosshair textures OR an enum (ECrosshair::Normal) or whatever

[cobalt gulch]

im not sure

[faint pasture]

Press button -> pass texture or enum or whatever to what needs it (PlayerController, crosshair widget, Pawn, whatever)

You can pass the texture itself OR an enum that's used to choose a texture OR whatever else you want

[cobalt gulch]

I have no idea how to do this lol

[faint pasture]

Your crosshair is a widget right?

in game, during gameplay

[cobalt gulch]

All of the crosshairs are in a single widget yea

But seperate from the button which is another widget

[daring oar]

Guys how do you come up with new game mechanic which never be create before?

[faint pasture]

Just think real hard and it pops out

Hurts sometimes

[daring oar]

hahaha nice one

i have one day to do it xd

is for my uni work and deadline is tomr

[faint pasture]

Well then start a-thinking

Here's one for free,

PLAY RISE OF KINGDOMS TODAY

[fast blaze]

hi all maybe somebody can help me while I'm moving character to certain position, the camera is flying from the PlayerStart default position in the scene, how can I set it immediately in the same place as an actor? thank you.

[daring oar]

is see thank you

[reef marsh]

Why aren't you setting the location of the component you want to move?

[obtuse yoke]

Any idea why the input isn't getting disabled? I checked and the OtherActor returns the correct actor.

I also checked that the overlap actually works

[fast blaze]

I need to select a root component of the character not a pawn and move it?

[faint pasture]

What exactly is the problem, you are moving the character and the camera isn't instantly moving as well?

[reef marsh]

Yeah, I'm not understanding what the issue is here. If you're needing to move hte camera, move it. Is that not working? If you're moving the pawn, the camera should go with it.

[faint pasture]

Maybe he has a spring arm component with camera lag and when he yeets his character to the other side of the map, the camera has to swoop over

[reef marsh]

ah yes, good thought

[devout condor]

with the array get node, what is the difference between get copy and get reference?
the description describes that you can make changes with a reference, but would you not have to make the same steps with a copy?

[thin panther]

an array reference makes changes to the original

[mental trellis]

If you get a copy and make changes, you will need to update the version in the array

with a reference, you do not

[thin panther]

if i set index 0 on a copy to 3, and do nothing else, then my changes are lost

if i do the same to a reference, then they automatically reflect in the original

[devout condor]

how is it 'automatic' do you still need to use the set node?

[thin panther]

yes

any changes on a copy, need to be manually reflected in the original

not so much so in a ref

[devout condor]

i'm still confused, you would still need a set node in both situations if you want to change the value?

[thin panther]

yes

[devout condor]

they sound like they are the same, I can't discern any difference between them

[thin panther]

one copys its values into a separate thing, the other basically tells the code "hey whatever you do to me, just do to the original instead

[mental trellis]

If you plug in the reference node into a set struct members node, it should update the value in the array

Rather than updating a separate copy

Or a set value node, w/e

Probably.

[thin panther]

imagine you copy paste an asset, and you change some things in the copy, it doesn't affect the original <- this is your copy node

now instead, change the original <- this is your ref node

[devout condor]

yes, but the change the array element you need a set array element, right?

[thin panther]

yes

[devout condor]

are there other ways of changing a array element?
cause (as far as I know, and clearly I don't know that much) both give you a number and if you want to change that number you set array element?

[thin panther]

thats how you change an array element

its just with a reference, that changes the original, with a copy it doesnt

[devout condor]

I'll have to figure this out latter, I'm working on a horrible headache

[thin panther]

i highly reccomend looking at programming principles, the concept of reference and copies is an extremely common one, especially in c++

[vocal bolt]

What type is this? I can't remember :S

[thin panther]

gonna need a littttle more context than that

[daring oar]

can samone help me to re create this mechanice ? https://www.youtube.com/watch?v=6TUfORLKXJs&t=301s&ab_channel=LogicLeo

[vocal bolt]

I'm trying to remake something I made as my starter project, this was months ago though and I can't access the original files. I've done everything apart from this one variable but I can't remember what it was.

It's something to do with a widget, but that's all I got. I can probably work out what it was if I know what that symbol stands for

[thin panther]

the rest of the video appears to explain what he did

[thin panther]

ah yeah thats a slight problem

what was the variable used for?

that might help

[vocal bolt]

This appears to be the only use of it (that I took a picture of)

[daring oar]

im stupid and new so cant undestand what he done

[thin panther]

he shows you the code

if that can't get you started, look at something simpler

[thin panther]

it seems tray could be something like a panel, horizontal/vertical box then

[vocal bolt]

That's what I assumed, but the symbol is different, could it be possible that they changed it between 5.0 EA and 5.0?

[thin panther]

what is alert cache

what does it look like, what's it used for

this sleuthing is fun

[balmy light]

does anyone here have knowledge with the water plugin

[vocal bolt]

Sorry, terrible at explaining things 🙃

It's a simple notification system:

-Alert Tray is a widget that gets placed on the main HUD
-Alerts can be sent to the Tray
-Caps out at 5 (on-screen)
-Any Alerts past that are stored in the Cache
-After X time or being dismissed, Alert is removed and the next one from the Cache is added

[thin panther]

ok but do you remember how alerts were layed out, cause this can help

[vocal bolt]

What do you mean "layed out"? Like actual layout on-screen? Or where stuff is/was in the BPs?

[thin panther]

the former

how is it on screen

[vocal bolt]

Ah, not done that part yet.

It should be a fairly blank Horizontal Box that gets placed on the main HUD, then the Alerts (Panels with some pictures) get added to the HB list

AHA

Found it, dunno why I didn't check that first

Thank you for letting me talk that one out

[daring oar]

how to make a bind event to Warped?

[thin panther]

damn you didnt check my suggestion of horizontal box?

that would have saved some time lol

[fervent raft]

What is the "Player Controller"? Is it something I can edit?

Also when I'm making a new project do I need to enable ray tracing from the getgo or can I add it in later

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Framework/QuickReference/

[fervent raft]

That helps somewhat but for example in the default third person game I can't find the player controller actor

[faint pasture]

It might not use a custom one

What are you trying to do where you need a custom player controller?

[fervent raft]

Nothing in particular I'm just trying to understand everything that is controlling the player in the example game

For example I don't understand what is causing the mannequin to spawn in when I run the example

Likewise I don't understand what the controller is... maybe it does not exist as a separate actor and is only referenced in nodes in the character blueprint?

[faint pasture]

Controller is an actor spawned at runtime. Read up on the core classes GameMode, GameState, PlayerController, PlayerState, Pawn, Actor

[faint pasture]

For that specifically the GameMode gives the player their PlayerController and Pawn (mannequin dude).

[drifting socket]

Can anyone help me with this? For some reason its colliding with my character but not the world, which makes no sense.

[fervent raft]

I understand both now thank you

[faint pasture]

The PlayerStart is just used to choose where to spawn.

It doesn't do any logic

It's just a marker really

[reef marsh]

Right, stated incorrectly by me

I was about to elaborate and say that if you have a PlayerStart, it'll handle the spawning automatically but it needs that actor to do it automatically

Or correct myself more than elaborate I guess

But thank you

[dusky jewel]

hello 🙂

i got a question about widgets

[bleak swift]

Graph wise?

[dusky jewel]

well i made a widget with buttons but they only work when i make the widget world space i was wondering if there was a way to make it work in screen space....

[bleak swift]

Show code

[dusky jewel]

im pretty sure its not my code.... im using blueprints... not sure what ud like to see----so i got an actor with an actor child component that has the widget,, when u get close its set to visible but unless the widget is set to world space my widget interaction component dont work.... so it could b a setting on the widget interaction comp or idk something im missing... i can show you some code but im not sure what ud like to see first =\

[brazen pike]

If its a widget that isn't applied to the viewport but instead attached to an actor (for instance a button on a wall) then I'm pretty sure it HAS to be in world space as it isn't 2d

[reef marsh]

You can put a widget in screen space as an actor component

if that's how this is being done

[brazen pike]

Then disregard what I said 😅

[reef marsh]

😄

[dusky jewel]

well i had some info i wanted to pass on to a widget from an actor but i couldnt so i attached a child actor component with a charactor to take the info and pass it into its widget to display... so yeah 🙂 i guess its not gonna work.. its more about the look of the widget cuz i could do it in world spacve but it looks horrible haha xD

[thin panther]

child actor components are notoriously bad

also you could always expose some variables on spawn, and then pass in the data when you create the widget

[dusky jewel]

haha yeah but im pretty sure its not the problem here lol

mmmmmmm

[thin panther]

wel no, but its still an issue that needs to be resolved

[dusky jewel]

soo

how would that work?

[thin panther]

for your widget you could do this

pass it in when you create widget

it adds the variables as inputs on the spawn node

there, owner, start speed, and instigator are exposed on spawn

do something similar with your ui

then you can just do the usual get close > make widget, get far > unmake widget

[crimson saddle]

I am doing some damage dealing in my game and I am using the DamageType system. I want players to be able to combine damage types, though. What is the way for that to be done?

[thin panther]

ideally to save performance you would not create and destroy each time, but instead hide and unhide

[thin panther]

what do you mean, like a weapon could do both fire and electrical damage?

[dusky jewel]

hhmm ill look into it thankz 🙂 ill b back lol

[thin panther]

no problem, i likely wont be on, cause its very late in my country, so i wish you luck :)

[crimson saddle]

Yes exactly

[thin panther]

so the way id just have multiple damage types listed on an actor

so say id have variables that say i want this weapon to do 12 fire damage and 5 poison damage

then for each of those, apply the damage of that amount and type

[crimson saddle]

I am using unreal's built in damage system, which only ever seems to pass one damage type per attack

[thin panther]

exactly

so you attack multiple times

the numbers for fire and poison are gonna be separate

so you just damage the thing twice

then do your standard weakness detection or whatever in your anydamage

[crimson saddle]

I was thinking of that, but then stats dont really stack in as fun of a way.

[thin panther]

they do

in either way you are gonna be doing an amount of fire damage and poison damage

[dusky jewel]

wait ok so i recall why i did the child actor thing i cant actually create a widget for an actor so no way to pass the info on begin play or construct 😦

[thin panther]

what do you mean by create a widget for an actor

[dusky jewel]

so i got an actor BP and i create child bp from it for different items and i want to display the items dmg and stuff...but its an actor i cant create a widget from that bp

[thin panther]

ye you can

[crimson saddle]

In my case I'm also using it for bonuses, so I would like to be adding those bonuses together. For instance one damage type might penetrate armor. So you could have penetrating fire damage for instance

[thin panther]

you just need a ref to player controller

[thin panther]

this sounds like something that may benefit from GAS

[dusky jewel]

lemme try it

[thin panther]

gameplay ability system can be setup to work with status effects and stuff like that

[crimson saddle]

Scary

[thin panther]

very scary

but it sounds like the best solution

this sounds like a complex system

which is ideal for use in c++

[crimson saddle]

Is it a necessary evil for my project? On my end it's the equivalent of just adding +1 penetration and +1 fire damage to the same attack

[thin panther]

could actually reduce a lot of headache

you would either probably need to use my suggestion, or build your own damage system, or try a c++ implementation

its not a necessary evil by any means

but a reccomended one

would also help clear up bp spaghetti

[crimson saddle]

Hmm, so no way to do it with damage types? Sadly it's not just a contained system, I'm using plugins that need the damage types too

[thin panther]

ah

you can do it

like i said

you would damage multiple times

the penetration thing may be another can of worms

but

for different damage types you can just damage multiple times

[crimson saddle]

Maybe a blessing in disguise. I could have a system that combines damage if it's dealt in quick succession. Honestly that might make for an interesting system on its own

[thin panther]

but with GAS you could just say apply fire damage and apply some poison damage, and then have them take effect

[crimson saddle]

Penetration in my case is just a stat thing for calculating armor

[thin panther]

well then thats another thing

damage again with the penetration value

damage doesnt have to detract form health

[crimson saddle]

Yeah I could just hold it for a second and mix anything incoming for like a second

[thin panther]

if dmg type is penetration then take away from armor, and then handle weaknesses

[unborn compass]

So I'm following a guide that tells me to change something in "Global Post Process Volume" but my world outliner doesn't have that

anyone know if i can add it or how?

I can add "Post Process Volume" but i don't know if that will work the same

[tiny vale]

Has anyone used Lyra yet? if so what do you think of it?

[rough eagle]

Hello, for a skill, i'm disabling my character movement, and make it move "by hand" on a timeline. (with set actor location(sweep)). i would like to detect if that movement is hitting the floor (to play a floor hit montage instead of a wall hit montage). how can i do that ?

[supple bane]

How do I lerp from 0 to 1 in x seconds?

[rough eagle]

noha, use a timeline

[tiny vale]

timeline

[supple bane]

ty

[supple bane]

can I have the length of a timeline depend on a float?

[rough eagle]

i usually set the lenght to 1s, then change the play rate

[supple bane]

alright I will try that

[supple bane]

How did you get the Target for the 'set play rate'?

[rough eagle]

on your variables, "Components"

[supple bane]

Im not sure what the math would be for this next part but what I need is to have the lerp end at the same time as a delay. If my delay is 0.5 then I need my lerp to go from 0 to 1 in 0.5 seconds

[maiden maple]

How do I have a reference to a function as a global variable? I have an “interact” component that, even interacted with, should pass a reference to a function I can set in the editor. Also how do I add variables to a data only component

[supple bane]

I figured it out, I divided 100 by 60 to get 1.666- then just divided 1.666- by the delay

[maiden maple]

Would it be an “event”? I’m unfamiliar with unreal’s data types. I’m looking for the equivalent of an Action<> in c#

[reef marsh]

I'm not sure I understand what you're doing. Also, what kind of component are you trying to add variables to?

[reef marsh]

In the editor on the left under variables, click the + or you can use the drop-down under "Add" and choose variable. If it says it's a data only blueprint, just click the hyperlink to open the full editor

[maiden maple]

I have this Interactible component on my actor. This component should have a reference to a function in another blueprint. I want the player script to be able to raycast to an object, get the Interactible component, and get the reference to the proper function/method/event/whatever to call within this instance of that component, and call it

Im just not sure what data type that is in blueprint.

in c++, you can pass a Function<> as an argument in a method; I want something like that

[reef marsh]

What is that Interactable component type?

[maiden maple]

What do you mean? Actor component? Blueprint?

[faint pasture]

Nah fam you want a delegate

OnInteract

unless you're doing something fancy

[reef marsh]

What is that screenshot of?

[maiden maple]

an actor

[faint pasture]

He has an interaction component and wants the actor to implement OnInteract on behalf of the component i think

That could be an interface

But I just do it by an interaction component and delegate

[reef marsh]

I wondered if it was an interface but I don't recognize that stuff in the screenshot

[maiden maple]

oh thats because it's UE5 lol

[reef marsh]

Oh maybe that's why lol

[maiden maple]

okay, so I need to make an interface, somehow

[faint pasture]

You could make a delegate on the component so the actor can hook into BeginInteract and EndInteract

[maiden maple]

no idea what any of that means. Well, I know what a delegate is, sort of

[reef marsh]

Interfaces are easy to make and implement so if you go that route, it isn't difficult either. But that won't solve your current conundrum

[faint pasture]

Having both an interface and component is a bit redundant IMO, you can either add interaction to an actor by

1. Adding InteractionInterface to it and implementing Interact
2. Adding an InteractionComponent to it and doing stuff on InteractDelegate.

[reef marsh]

It just gives you something to call for any of your actors that implement it

[maiden maple]

Okay, I made an interactible interface and now I can implement that function in my Door component. Got it. Now, can I test if an actor has a component that implements that interface

[faint pasture]

Interface is simpler but we went with component so interaction can be said to happen at a location (Button, doorknob, etc)

[faint pasture]

Are you mixing up component and actor?

[maiden maple]

Also for context normally I work in C# and Unity

[maiden maple]

No, I'm raycasting for actors, and I want to see if i'm hitting one that has any component that implements this interface

[faint pasture]

What is your Doorcomponent?

Typically you'd do a door by implementing Interact in your DoorActor to run the timeline opening and shutting playing sounds etc

[reef marsh]

Why not implement it on your actor? So you can just call interact instead of checking the actor's components for the interface

[maiden maple]

Well some actors are interactible, some arent

[faint pasture]

You just add the interaction interface to those that are interactable

[reef marsh]

If the actor doesn't implement interact, no harm done by calling it

[maiden maple]

oh, i see

[reef marsh]

Adriel, if you were to call the interface function on an actor, will it call it on components as well?

[faint pasture]

No, that'd be cool as hell tho

I wish you could implement an interface on behalf of an actor, don't think it's a thing though. Not automagically anyway.

[reef marsh]

Had never tried that but curious thinking about it now

[maiden maple]

OH. okay. got it. I can make an actor blueprint inside the content browser.

okay got it

Pardon me i havent used Unreal Engine in years

so I have to remember how it works

[faint pasture]

For instance, this is how we do interaction with components instead of an interface

[reef marsh]

No worries! We're all here to grow

[maiden maple]

and then I do this in the player script. fantastic

[faint pasture]

So a generalized interaction system could be.

Choose Actor
Interaction interface call

OR

Choose Actor
Get component by class (InteractionComponent)
Call Interact

[maiden maple]

The reason I wanted to do a component instead is to have a more ECS based approach for flexibility

[reef marsh]

You can still use a component to handle it

Pass off the call to your component that handles the interaction

Or however you like

[faint pasture]

And on the recieving end, they either implement Interact from the interface, or hook into dispatchers. Here's our interactioncomponent, nothing to it.

[maiden maple]

I could do both, I could check if it has a component then call interact, and if not I could just call the interface. But then I'm back at square 1; how do I specify what the InteractiveComponent should do, because making a new component that inherits from the interactive component seems wasteful

[faint pasture]

I wouldn't do both

[faint pasture]

Do it like this with the dispatcher

That event is in the actor but from the component

the component says "Hey someone touched me" and the actor does its thing. A chest opens, a door opens, a weapon is picked up, etc

[maiden maple]

what am i looking at here

[faint pasture]

Here's what our teleporter does when interacted with

You're looking at the implementation of interact on the actor, from an event dispatcher in the component. All the interacting character does is call Interact() on the component

[maiden maple]

How do I dispatch a message to an object, then

[faint pasture]

You know all these things that you see when you have a component selected?

That's the components dispatchers/delegates

When I have my interaction component selected I get this list, the top 3 are custom added to the component BP

so the Actor can do something when that dispatcher is called on the component

Here's what the business end of my Interact logic on the character does.

[maiden maple]

Wait, so, when you interact with your teleporter, you are sending a message to the C-Interactible, which then sends a message to the rest of the actor?

[faint pasture]

Yes, the flow goes
E Keyboard Button -> InputAction -> Target selection function -> On Interact (which is a dispatcher in the interactioncomponent) -> Dispatcher in Component (automatic) -> OnInteract in TargetActor -> Whatever Interaction means for the actor.

All you have to do to implement interaction in a new actor class is add an Interaction component and implement OnInteract

A dispatcher is pretty close to your initial request of how to tell the component what function to fire when interacted with

in fact you CAN do that with binding but I just implement it directly

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/EventDispatcher/

[terse goblet]

I created 2 widgets and added to viewport
widget 2 is over widget 1
windget1::onMouseButtonDown prints string for test
widget2::OnMouseButtonDown returns Unhandled reply and also its visible

why widget1's (which is below widget2 that returns unrandled reply) OnMouseButtonDown doesn't get called?
doesn't unhandled reply means "pass input through?"
Asked in #umg already.. I ain't sure umg was enough tho. Sorry for double messaging

[maiden maple]

so like... this?

1. Player raycasting
2. InteractibleComponent
3. Door Actor (Implementing interface)

[unborn compass]

does Class == Parent Class return true? sorry if dumb question. If not, how can I return parent class of an actor?

[faint pasture]

@maiden mapleWhy you still using an interface?

[maiden maple]

That's the only way I could think to call an event on a non-specific object

[faint pasture]

Go in your door actor, select the interactioncomponent, scroll down to events, click the green plus next to CallEvent

[unborn compass]

found it, its "class is a child of"

[maiden maple]

ooh, ok. so the component has no logic at all then

[uncut smelt]

Random question - if I have a widget blueprint for example - and place 1000 sliders on this widget - change each slider to a different value - save the widget - than load the widget - do the sliders retain their value ?

[faint pasture]

Yeah no logic. You could presumably add some later if needed but prolly wouldn't be

[unborn compass]

Guys how can I set a an object variable to null?

just use a set node with no connection?

[spring kayak]

Question about Blueprint Interfaces. I'm trying to update the speed variable in an Animation Blueprint using interfaces and for some reason this setup isn't working. Any ideas?

Character BP

Anim BP

[maiden wadi]

You're calling the interface on Self. Which is the Character. To send that message to the AnimBP, you have to pass a reference to the AnimBP.

However, this is not a good use of interfaces. AnimBPs can easily poll their owner's velocity in their update function which is tick as well via TryGetPawnOwner

[glacial stream]

Hello everyone can anybody help me?

https://www.youtube.com/watch?v=ELtWNVfkx38 i try to make procedual building as in this tutorial and i have problem i cant find this node in ue5 and i try make multipy node but i dont see default bar when i compile it

[faint pasture]

@glacial stream show what you see when you drag off the index pin and type *

[faint pasture]

Bruh you have a multiply in your graph right there

Multiply is templated now, it's just a multiply.

[glacial stream]

Okay many thanks i use it now BUT i dont see default graph when i place my script at world

how i can fix it?

[faint pasture]

What is a default graph?

[faint pasture]

That's a variable, not a graph

You need to mark that variable as instance editable

[glacial stream]

here?

[faint pasture]

That's not "Length Of Mesh"

[glacial stream]

WOW WOW WOW

many many thanks man

[red fossil]

👋 Anyone know if there is an equivalent to the "add torque" node that applies to character movement instead of physics simulation? I need my character to physically roll and pitch but without physics sim

Maybe I could just use "set rotation"?

[stiff leaf]

Add Controller Yaw/Pitch/Roll Input?

[red fossil]

Could be it, but it just controls the camera. I suppose I could tell it to copy the rotation to the character capsule?

Ok, that works, but it's jittery for some reason

[urban haven]

Hi all, Variant manager question: Can I duplicate objects/Blueprints using the variant manager? Like I would want 2 or 3 cars instead of 1. Is this possible?

[white elbow]

how do you change the socket's position based on attached components? I want a different front grip placement based on the barrel (short vs long)

maybe make skeletons for barrels and merge them?

and the barrel skeleton would contain the socket

or maybe just add offset to the socket?

[spring kayak]

Thanks, I tried it that way and it's working now!

[urban haven]

Not an expert by all means, but if you have 2 different meshes ( long and short barrel) you can have different placement of the socket. It is also possible to offset your sockets, but that you have to google...

[fast escarp]

Is their a clean way to cast an array of base class to inherited class?

APlayerState -> AStatierPlayerState for example

[mental trellis]

Have you tried literally just casting the array var?

I guess bp doesn't support that.

[fast escarp]

yeah it looks like bp can only cast single objects

.<

I'll have to just write a helper function for it

[still rain]

I cannot find my custom function created in blueprint A in blueprint B

anyone could help?

had this addcoin function but cannot find it in another blueprint

[obtuse herald]

You're casting to the wrong type

Add Coin is in BP_FloorTile

[still rain]

!

thanks...

🥲

[obtuse herald]

You're welcome

[winter flower]

Anyone have any idea why "Event Recieve Smart link reached" won't fire? 🙂 Every tutorial i find seem to have no issues with it, but my character only walks around in circles around it indefinitively, and not triggering the print string message? Have tried massaging the end points, using simple links, changing scale and much more. Any ideas for troubleshooting would be accepted with huge thanks 🙂

[lusty wraith]

guys im really really stuck . Im trying to fire off an action only if the player has done something else beforehand (clicked on the mixing button inside a WB). Ive tried setting the boolean 'IsMixed?' after the button has been clicked (event graph on the left), and then calling the WB and bollean 'ismixed?' in my other BP, attaching it to a branch (event graph on the right). It just doesnt work. Anyone got any ideas? im guessing its simple, but i cant do it 😦

[brazen pike]

How is it not working? The boolean doesn't give you what you want? You are getting errors? What's going on

Ah I can see the problem actually

You're not setting the reference to the widget properly

so it has no idea what it is getting since it is getting a variable from nothing

[lusty wraith]

ye i thought that might be the case. how i tried to reference it is: created a variable, set the variable to my WB object type, as shown in the right event graph. Do you know what other steps i need to make to reference it correctly?

[brazen pike]

Do you happen to be creating the widget in the vending machine bp?

or somewhere else

[lusty wraith]

No, its created outside of the vending machine BP

[brazen pike]

Do you switch that boolean multiple times? Or is it a thing where it is false until its pressed, then it is true forever

[lusty wraith]

Nope, once the boolean is set once, it stays like that forever

[zealous fog]

Does your vendingmachine BP have the right value for the PC_IN_VB variable?

How do you get the reference

Because the default value is empty you need to set it somehow

You can print string and see if it has the right reference

[brazen pike]

Okay well, not sure if this is the best way possible but it should work. Find whatever blueprint creates that widget (I'm gonna call BP_X), then set the widget as a variable. Then you want to go to the vending machine bp and create a variable for BP_X and make that variable "instance editable", that is a checkbox on the right side of the screen. You should then be able to click on the vending machine and select BP_X in the viewport to set it as that. Then you can get BP_X variable, then get the widget from that, then get the boolean.

[brazen pike]

Its just an empty variable, hasn't been set

[zealous fog]

Where do you set it in your logic

Can you show that part of the BP

[lusty wraith]

The PC_IN_WB is where the boolean is. I referenced it in the vending machine BP by creating a variable in the vending machine BP to the pc inter_wb.

[lusty wraith]

Thanks for this, i will try and see if it works

[zealous fog]

You didn't reference it because its empty

Look in the bottom right

[brazen pike]

Yeah so the problem with this, is that you have told the variable what it SHOULD be (it should be this widget) but it doesn't know which widget you are talking about. Because there might be multiple on the map. You need to tell the BP which widget it should reference

[zealous fog]

You created a variable that can hold a reference to such a widget

But you need to set that reference

[lusty wraith]

yes youre right, here
