blueprint

[surreal peak]

You can also give that a parameter

In case you want to pass the Json stuff to whoever bound to it

Just delete the folders and package again?

[steady night]

same thing

a new build builds with an other v inside

super strange

[modern radish]

I have this so far, but I'm failing to understand how the event dispatcher I created in the gameinstance connects with all this

Ahhh, BindEvent?

or Assign?

[surreal peak]

It's the same. Assign just spawns an event on top. Just do Bind

[modern radish]

does that seem right?

I think it works, but just to be sure

[surreal peak]

Yeah the Create event node alles for a wireless bind

If you connect that to the red pin it will change a bit

There is then a dropdown you can select matching events and functions from

[modern radish]

Okay I see now

[surreal peak]

Yap

Then you don't need the red wire to the custom event and you can put that somewhere else

Or put stuff into a function

I would also just call that function on True

Instead of connecting the wires twice

[modern radish]

Okay yeah that makes sense.. then I would rename my boolean

is that what you mean?

do I need the Branch at all?

[surreal peak]

Yeah

hello everyone, i am trying to play the video in media player at specific time using blueprint in which i can speicify the start time and stop time of the video to play and stop but i donno how to do so ?
Can anyone help me out in this?
(i am using a single walkthroug video and i have multiple screen on which i want to play that video but according to that specific screen it starts from that specific time that i would set up in blueprint and my screens are in widget bp)

[spark steppe]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Media/MediaPlayer/Seek/

[worldly tartan]

i tried this but it is not working like if i have seek function in my bp then my video even doesn't play so how can i set the time there?

[spark steppe]

have you tried to call play before or after seeking!?

[worldly tartan]

after seeking i tried but still didnt work

[spark steppe]

there's also play and seek

[worldly tartan]

i tried that tooo

but nothing works

i am not sure what i am doing wrong?

[quasi nacelle]

Hi guys.

Is there any way to mark functions from BlueprintFunctionLibrary as UObject safe?
I found a way to use them in UObject (just drag and drop them) but they show warning about unsafe usage (i know i have to pass world context to use tem in safe way).
But i would like to use them just like cpp version of static functions from cpp BlueprintFunctionLibs (i can add them to uObjects from context menu).

Is there any way to do that? Or i have to rewrite them to cpp?

[remote meteor]

there is a way but it requires cpp to override the GetWorld() function where you can get it from the outer

then you can use BPFL normally in them

[quasi nacelle]

THX

[rare bloom]

new guy here, using the tutorials.
what now?

[upper badger]

there has to be a more elegant way of showing collisions in the editor, right? because this was all i found...

[ionic palm]

You can press the apostrophe in game and then use the numpad keys to reveal collision I believe it is num pad 4 in the apostrophe menu

[zealous scaffold]

Hey guys, has anyone worked with custom movement modes for the character movement component? I'm trying to implement one but i can't make the character move while in custom mode. add movement input is ignored both on standalone and client server

[ionic palm]

You can also see collisions if you double click on the original mesh or model and then show collisions there on the top left "show" menu

[ionic palm]

I think you need to use C++ to mess around with custom movement nodes I could be wrong though but it would seem like the sort of thing that requires scripting

[upper badger]

im testing overlapping BP actors. i know i can type show collision in the apostrophe menu, but i need to see it every time i test something, which is pretty often

[ionic palm]

I mean it's pretty straight forward what you have I dunno how you can make it more "elegant" other than adding the one node to visualize it on play haha

[upper badger]

i guess lol, i just thought there was a debug setting or something that i was missing

thanks :))

[zealous scaffold]

The functions are the same though

[ionic palm]

Nah I think you are doing it the best way you can. Np buddy best of luck 👍

[versed sun]

Compile

[finite flax]

Can someone please tell me how can I call a reference bp in easy step? The 2 pics below indicates what I want to achieve

[mental trellis]

It's a bit more than 2 steps

[feral parrot]

Does anyone know is there a setting of the spring arm when the player’s camera slides along the collision of a building when you get close to it?

[zealous moth]

that's actually perfect since I need blocks of time

[ionic palm]

Hi guys I am trying to figure out a way to stop weird physics when jumping or leaving the ground at all on my sailing ship.

You can see what I mean in the clip;
https://streamable.com/2ey1a0

My issue is basically the ship and characters velocities are combining and the ship is moving beneath them when airborne.

I had an idea to subtract the ships velocity from my characters overall as you see in my screen but I am unsure how to hook this up or where to look for similar examples.

[south lintel]

Hi, I’m a complete beginner to game development and Unreal Engine in general. I’m making a game where the camera can either face the left, right and front of the office the player is inside, I made the left and right click buttons move the camera to sides with “rinterp to constant” and event tick but this method is extremely basic and awful since it adds controller yaw input and instead of looking at three specific sides, it just continuously rotates either left or right. The idea is similar as how the attic night works in TJOC Story Mode but instead of rotating the camera to look behind, it does the same thing by looking at the sides (linking a gameplay of TJOC later in the message), how can I implement such mechanic, while also making it interpolate between the positions like in that game? Thanks!

https://youtu.be/07NcqTpaoNs?si=POZbzzDxuFwgZ6uj

[trim matrix]

Guys what is preferred Validated Get of variable / run Is Valid node?

[mental trellis]

You can turn off using controller input for a start

[south lintel]

So instead of controller input I’ll just rotate the camera?

[mental trellis]

Yeah.

You have a final transform, no?

Just lerp to it.

[south lintel]

So each button will set the rotation to the specific one and by using lerp the rotation will get interpolated from the original rotation to the final one?

[versed sun]

Use different methods depending on how you need it
The Function version (f) will return a Bool
The Macro version (?) will return a Branch style
The Convert Validate Get is a different way

[tawdry surge]

Validated get is 17% faster, so if you can use that one, you should

[south lintel]

I've been able to rotate the camera through set world rotation and the keys changing the rotation to the correct ones for each side, but now the lerp instead of interpolating the movement, it just rotates the camera 50% of the distance from the original angle to the final one each click instead of just rotating smoothly, I've probably messed it up or misunderstood the suggestion lol

[lunar sleet]

Que?! 😱 I had no idea 😅

[quartz stag]

Does anyone know why the inherited won't let me add any interfaces (never used this before)

[lunar sleet]

Because that’s where interfaces get inherited from parent classes

If you’re following some crappy tutorial be aware that in 5.0/5.1 iirc there was a bug where the 2 were accidentally reversed

[quartz stag]

So instead of putting the interface into the inherited, it would be the other one I put it into?

[lunar sleet]

Yes, now that it’s fixed, it makes logical sense

[quartz stag]

Thanks

[warped saddle]

idk if this is right text channel but i am creating inventory system and i have 2 indexes, source index and destination index, and like when i drag the item it print strings source index and when it drops it should print destination index but it prints the same index even tho i dropped it somwhere else. The draging and dropping works but i dont understand how is destination index becoming like the new index and how the drop actually works

it works but i dont know how is the new index becoming new, because when i print it it shows the same value instead of new one

[lofty rapids]

hard to tell without code

[warped saddle]

first is drag function second is drop and the third is in my inventory system

in the last picture it should print new index that i dropped in the slot but it print the old one

[lofty rapids]

maybe because you have or and the component is != so your indexes could be the same

[tight pollen]

hi

i use WidgetSwitcher, if something is hidden then not Tick?

[versed sun]

I didnt see a problem, but here's something handy to help de-clutter
When you have a Function , you can Get the inputs (can't set)
I think this would help you see exactly what you are printing

[warped saddle]

thanks guys i will try to do those

[remote meteor]

i would also give that get node a note that it is a param so not to confuse people 😆

unreal probably can improve by make a small visual difference to the get node to differentiate whether its a class variable, local variable or param variable

[fallow yarrow]

I'm working with a grid setup with instanced components on the actor, and trying to find a way to identify the components on linetrace, is there any way to attach data/info to a component that you can retrieve and use? For example an ID/Name to use later ?

[ionic palm]

I have something kinda what you are talking about to posses my sailing ship, provided what you are casting too is a pawn. I'm not sure about retaining it though in the long term

[ionic palm]

You could probably add the result to an index or something that is stored in your world blueprint

[fallow yarrow]

I don't see how it would work to identify the component that was hit. The problem currently is that the return displayname and objectname is the same for each instance component, not unique. I was going to make an data array with information, however don't have anything unique to identify each components

[versed sun]

yah , I wish there was a visual difference between Variables and local Variables
Local Variables could have a dashed morder or something

[kind willow]

I have capsule trace which activates when player tries to stand up from crouching, but when it looks for collision, it also detects triggers which have their collision set to "overlp" and not "block". How do I change this to make it only detect collision that blocks movement?

[versed sun]

Im having a slight brain fart , but one of these IS the index of the ISM that you hit

Just cant remember which one

[fallow yarrow]

Hmm, really? Because I kept getting 0 for them. Gonna do some quick test again

[versed sun]

well, 0 would be first index

IF thats the one your hit

[fallow yarrow]

As you can see, the results is always -1 and 0, I think it's more about the what is hit first, starting from 0 as you said.

[remote meteor]

StaticMeshcomponent?

I supposed they should show up as instancedstaticmeshcomponent if they were instanced

[fallow yarrow]

InstancedStaticMesh, yeah

[gentle urchin]

They're all instances of the same component, right ?

And not 800 components.......

[remote meteor]

Can you show how you spawn the instances?

[fallow yarrow]

Yeah, I wanted to avoid making a lot of actors and use instance instead

[alpine monolith]

The debug is saying you are hitting StaticMeshComponent, not Instanced one. Do you have proper collisions on the ISM? Aren't you perhaps hitting the ground underneath?

[remote meteor]

Oh yeah

[fallow yarrow]

Oh? I bloody well hope not... but at the same time I do, because it might help haha

[lofty rapids]

i was going to ask that because it didn't have hit blocks it looked like

[remote meteor]

The hit debug point isnt shpwing up either

[fallow yarrow]

Ohhhhh, you right! let me see

.... ffs

[remote meteor]

It happens dw 😆

[fallow yarrow]

Ah thanks a lot. So much testing and trying different things, just for a damn setting not being set right earlier haha. At least learned some new nodes haha

[tight pollen]

is it possible to set variables by creating a widget (Child) for Parent?

do I necessarily need to create new variables in Child Widget and then set them in Parent Widget

?

[fallow yarrow]

And @versed sun , did get the correct index now 🙂

[versed sun]

which pin ?

[tight pollen]

someone?

[remote meteor]

Hit item

Element i think is for material index

[gentle urchin]

#multiplayer

[remote meteor]

Dont quite understand the question. Parent child as in class inheritance?

[fallow yarrow]

It was the Hit Item, seem it gives different numbers now

[tight pollen]

yes

in the Details panel I can set values ​​for these variables in Child

but I want to set these variables when creating the widget

[remote meteor]

Oh those variable

You can tick exposed on spawn

Then should be visible when you do CreateWidget

[tight pollen]

how?

i know, but how do this for child

all variables is in Parent

[remote meteor]

They should be visible as long the variable itself is marked "exposed on spawn" on the details panel of the variable

[versed sun]

^Once you compile/refresh

[remote meteor]

ah yes..

[tight pollen]

are set

[versed sun]

They will show up

[tight pollen]

on Exposed on spawn

works

I have no idea why this didn't show up before

maybe I chose the wrong widget 😅

[remote meteor]

The class selected on the createwidget is important

It bases of that

If its a variable, it depends on the variable type

[sick fable]

LOL

My character movement component

Just wiped itself

Again

Bruv

wt

f

Anyone know how to fix?

[sick fable]

actually everything in my character wiped

what

now my character is just a floating camera

with all blank details

[lofty rapids]

[sick fable]

bro how do I set up backups

because this happened 2 days ago

[sick fable]

I am right now 3 hours into the video you sent me lol

[lofty rapids]

not bad right ?

[remote meteor]

did unreal editor crash or something

🤔

[sick fable]

nope

just happened

I pressed play once and everything was fuced

[lofty rapids]

i saw somewhere around here thats a bug

[ionic palm]

Does anybody have any idea how I can get my character to exit my ship reliably with a transform lock on a delay or exit animation or something?

I'm having a lot of issues due to it being a moving surface.

https://streamable.com/sz5l6r

[sick fable]

Ye its good but I will skip all the manual coding for C++ parts of the video because I don't know about that lol

[ionic palm]

Are there better options than event tick for the exit sailing logic?

[sick fable]

bros making sea of theifs

[lofty rapids]

are you also controlling the boat ?

[ionic palm]

I'm trying to get the boats to work the same at least

[ionic palm]

Only when I posses it

[ionic palm]

It seems fine when I spam it but anything longer than a second at the helm it seems completely random as to where you end up

[warped saddle]

fixed it thx

[alpine monolith]

Greetings! I have a custom C++ AActor with a few components. When I look at the BP version of that class, in the Class Default details panel, there seems to me quite a mess, every property from every component visible and shown (image1). It that normal behaviour? When I create BP-only Actor and add some components through BPs, the Class Defaults seems clean as it should be (for example no transforms for every component) (image2).

I dont think that this is the proper behaviour, as the BP-only version just behaves differently with the Class Default properties shown. Anyone have any experience with this?

[tawdry surge]

No, that's normal

works the same when making a static mesh actor bp or character bp.
Anything declared in c++ shows in the defaults, anything added in bp doesn't

[alpine monolith]

Damn, it's just a mess in the class defaults, hard to orient in that with c++ classes. But at least now I know that it is supposed to be that way, was worriying I messed up some settings or smthing.

[stone dirge]

can ayone help me with fps weapon switching like I don't know how to do it. The only thing i can think of to keep the position of the weapon meshes is just having a lot of arms but thats inefficient so any better ideas? I'm pretty new so Id need a decent amount of health. Also this system had dual revolvers so right now i just have two identical skeletal meshes which are child two the respective hands of their arms.

[fleet lichen]

Hi, am new to Unreal Engine, and am trying to make a light that will turn off or on when the player is near them. But it doesn't work. Anyone knows why?

[lofty rapids]

whats with the branch to just true ?

quick way to switch between them maybe ?

[lofty rapids]

you probably want to set it false on end overlap

[lofty rapids]

is it turning on ?

[fleet lichen]

it is, i think

[thin panther]

Yeah that would turn on. Your issue is you're never evaluating a condition to turn off

That branch will always execute true because you've told it to

[fleet lichen]

oohhh

this one right?

so i need something that will say player is not near and turn it of

[lofty rapids]

you want it to turn off if not overlapping ?

[fleet lichen]

yep

[lofty rapids]

there is an end overlap where you can set player is near to false, and run that event again

[fleet lichen]

can i just connect "on componet end overlap" there?

[lofty rapids]

i mean technically you could plug it into the set player is near to false

[fleet lichen]

ohh i think i get it now

give my a min

this could work?

YES IT DOSE

Thx for help guys

[thin panther]

The branch in both cases is completely unnecessary and should be removed

[fleet lichen]

oh, true. thanks again

[thin panther]

No problem :)

[tight pollen]

I need to get the absolute position of a widget located inside another widget. How can I do this?

someone can help?

[lofty rapids]

I mean can you get the outer top left, then add the inner relative ?

or maybe there is a node for that idk

[cyan bone]

maybe this node can help you

get local top left is the position of the widget

do this to the parent and then do this to the child

then get the relative position

but im not sure. maybe someone knows this better

[lofty rapids]

is it #umg ? maybe might know

[drowsy steppe]

Hey guys, noob in need of help here!
I'm trying do make a mesh rotate when i press the letter A, and I got it working with this logic, but I wish to do it in a way where when i keep pressing the letter A the mesh keep rotating and in a smooth way, since right now it's not smooth at all. Any suggestions? Should be quite easy but can't figure out how to do it

[cyan bone]

you need to use rinterp for that

and the tick event

[drowsy steppe]

thank you for your help. i wanted to use it, but it's being used by some other logic, how can i bypass that?

[lofty rapids]

you can still use it, just put it at the end

or make a sequence

[sick fable]

Ok finally

just finished fixing my character by making a new one and changing everything to match it

Where you the one that told me about something about source code

so I can have project backups

for if this shit happens

[lofty rapids]

probably not, i never used source control, i could have suggested it idk

[flint wind]

Hey guys. I have a very extensive question, I basically need some guidance. Is it okay for me to post the entire thing here? Thanks!

[frigid swallow]

I have this issue where whenever I move my mouse, it just turns the camera without moving the player character at all. Any help?

[lofty rapids]

"source control" is definitely a good idea if you want to revert back from some error, i just use backups i'm not that sophisticated yet.

[sick fable]

ok how can I make backups lol

Just duplicate the project file?

[lofty rapids]

i just duplicate rename the folder, when you hover over the project just check the folder because it will say same name

can be a bit confusing but you can also rename them it's just a hassle

[sick fable]

can I see anything cool you have made

@lofty rapids

because you seem to know a lot

[lofty rapids]

i have not made a lot yet, still messing around, i only been using unreal for a few months

[versed sun]

Whats the general highlights about your question ?
Anyone that is around and is familiar with it might help

[lofty rapids]

i have a pretty long programming history so bps kind of click for me

[drowsy steppe]

thanks! I can't find the right "add local rotation" it gives me one with a purple dot and not three green ones like yours

[versed sun]

Right ckick the purple dot

You can do this for i think all structs

[drowsy steppe]

thanks! I didn't know this

[sick fable]

how can I recalculate my nav mesh

[minor dew]

Hey guys,
I've create an inventory system that based on a Map of Int: Uobject.
The system works and everything works great.
I forgot the maps aren't replicated.
Should I rebuilt the system base on arrays or can I continue as is and using server events ?

[drowsy steppe]

I did it like this, "rotazione" is being called by eventbeginplay, but it is not working, what did i do wrong?

[versed sun]

Time

.01 is smooth

[drowsy steppe]

right, dumb me, thank you

[versed sun]

and make sure the Delta Z is set to small, like 1

setting to 1 would rotate 100° a sec

[flint wind]

Well, I'm creating a "dynamic and flexible house building system", and with the first two words I mean that I'm not using a grid or modular assets so what I'm trying to create is indeed very complex. The main obstacle are walls. I want them to have variable height, inclination and curvature. In many scenarios, I need to accurately move individual vertices of these walls, which as of right now I only know how to do by using Procedural Meshes or Skeletal Meshes with a bone in each vertex (which is very resource wasting), and for windows and such, I thought of using the Geometry Script Plugin or slicing the wall to create some sort of frame. As I said, I don't really know how to explain this without writing too much. Thanks a lot in any case!

[drowsy steppe]

it is not rotating at all

[versed sun]

Plop a Print string on the RotateItem event so see if it ticks while A is pressed

[drowsy steppe]

print string doesn't execute

[versed sun]

and pressing A fires if you add a print on the A?

[drowsy steppe]

yes

[lofty rapids]

You changed your time from 0.0 ?

[drowsy steppe]

yes

i have to go now unfortunately, i greatly appreciate your help kind man

i will try to fix it later

[versed sun]

Well, I love Dynamic and Procedural gen and might be able to help
What do you have so far?

What value?
Setting Visibility has a built in check for all children

[flint wind]

Would you mind if I contact you later? I have to get off for some hours

[versed sun]

sure

[cyan bone]

Im trying to do map boundaries on my game.
From the videos i have seen thats done using box collisions on the 4 edges of the map.
But my map is not exactly a square.
Its more like a sphere shaped map, with mountains around.
Should i just brute force some box collisions inside the circular map?
Or there's some other way?

Maybe do something like this though it feels like such a waste of space

[desert quarry]

What's the best way to stop my character from moving during an interaction?

[ebon olive]

I cant delete a certain link that is connecting the two nodes. Anyone know why? 😦

its so weird. this is from state machine. I cant delete it off. Like i press Alt then click like how you normally do but it wont remove. I press delete even but it wont go away

[lofty rapids]

which one are you trying to delete ?

you can click the circles and hit delete if it's one of those

if it's one comming out of stunned or out, right click and hit break this link

hopefully that works, i tried in an anim bp and that seemed to work

[short phoenix]

I thought in the Blueprint Communications demo that there was a demo of a button that has an instance of a specific class as a variable, and it's able to call functions on it that become events inside the other class' blueprint code. Is this actually a thing?

[fleet lichen]

How can i connect custom event to two nodes?

[lofty rapids]

like two binds ?

[fleet lichen]

i need to connect the event to the two down timelines but idk how.

[lofty rapids]

you can run a custom event

just type it's name in and you can just plug that into exec to run it

[fleet lichen]

i need it to be the one up there

SEQUENCE

[lofty rapids]

wdym sequence ?

[fleet lichen]

the name of the node i needet to do it

[frigid swallow]

I have this issue where whenever I move my mouse, it just turns the camera without moving the player character at all. Any help?

[lofty rapids]

oh ok i was not getting it, you just want to run the bottom two as well ?

[fleet lichen]

i need to run the bottom one as well but at same time

if i plug them after the first timeline then it get delayd

Ok, there needs to be a better way to do it.

Am trying to do auto-opening garage doors but it look...not good

[zealous moth]

@faint pasture @lunar sleet in the end for a timer, even following your discussion, I put this on an interface binding:

as long as a starting time in seconds exists, you can subtract the current to get the delta seconds and extrapolate time

[zealous moth]

if you have a character, you can set the rotation to follow the camera

[zealous moth]

you cannot sequence timelines in the same event. Your best bet is to use 1 timeline and use math with the alpha to update multiple things at once

[cyan bone]

anyone know what i can do for a map boundarie if the map is circular?

[fleet lichen]

...to advance shet for me

[zealous moth]

capsule collider or sphere collider?

[zealous moth]

it really isnt. Your timeline is x in f(x). Use a graphing program to see how you can influence it.

[fleet lichen]

yeee, idk wahts that

[frigid swallow]

How/where would I do this?

[lunar sleet]

What do the 3 timelines do

[fleet lichen]

2 are for cloasing (rotation) and the other two are for positioning the doors

but its ok now, i realized i have bad pivot point

It's finaly wrok.

[cyan bone]

but how, unless i could inverse it.

like a inversed sphere collision

like this

or like

[spark steppe]

you just need a large cylinder without ends

unless you have flying units

[cyan bone]

or like this

[cyan bone]

yep thats a cylinder. yep no need for sphere. good point

ahh

i know what i can do

it doest need to be a circle

it can be a octagon

so like 8 box collisions

so something like this is not bad

[gentle urchin]

Hexagon that is

Octa - 8 - has 8 sides

[north lynx]

Hello!
I have a some sort of stupid question, I remeber that I can make movement of the player camera using timeline, but I completly forgot how to get X Y Z camera referances (those green outputs in timeline)

[fleet lichen]

they are just 3 separate timelines named "Camera X, ... Y, ... Z"

[north lynx]

Oh yeah!
I remember now, thanks 🧡
Sometimes I have goldfish memory...

[fleet lichen]

Me too, don't worry

[spark steppe]

oO what the actual heck

just use a cylinder with collision set to complex as simple

[fleet lichen]

Does anyone know why it's happening?

[limber parcel]

is there any way to display custom data in details window when using uobjects?

kinda hard to debug without seeing what the items actually are lol

[lunar sleet]

Use print strings or right click and watch the values at runtime. Debugging is 50% of development, it's important you learn how to do that

[fleet lichen]

i know now why its happening, but still dont know how to fix it

[lunar sleet]

why is it happening

[fleet lichen]

Sorry, English is not my main language.

[fleet lichen]

When I go inside the collision box, I trigger a "on component begin overlap", and that starts the opening of the doors, but when I leave the collision box, that triggers "on component end overlap" and that will start the closing of the doors. If I do both too fast, then it don't know what to do first.

[feral parrot]

Why is the camera not following the spring arm direction?

[lunar sleet]

ah, makes sense. Tricky. You could gate them with a boolean check but then you'll prly end up with the door not closing cause you left too fast

[lunar sleet]

you mean the rotation?

[feral parrot]

yeah

[fleet lichen]

yee, already did that

[lunar sleet]

rotate the camera itself.

if your camera is attached to your spring arm it'll rotate with it tho

[feral parrot]

it is a part of it but it doesn't rotate with the spring arm

[feral parrot]

it was a bug, working now

[feral parrot]

ah I got it, it behaves different when this setting is enabled, but I need it ti bo enabled, at the same time I need it berotated with a spring arm

[lunar sleet]

Which one, camera lag?

[feral parrot]

use pawn control rotation

I can't set it 45 angle

[lunar sleet]

It shouldn’t be affecting rotation, sec

Oh right it does, I forgot

It says it’s because it maintains its position relative to parent

Why do you need it enabled?

[feral parrot]

what would you recommend doing if I need to rotate the camera by Y axis when I stand close to a building? it should like sliding or something like that

[lunar sleet]

just grab the spring arm and rotate it

[feral parrot]

and i should see the character mostly from the top view rather than 45 angle

automaticly in the play

[lunar sleet]

there's a top down template if you want

[fleet lichen]

I just want to close my door. 🥹

[lunar sleet]

why don't you time gate it, so it can only close after a certain amount of time has passed

maybe even remove the close from the end overlap

just close it automatically if x seconds passed and the character is no longer overlapping (use getOverlappedActors + for each loop + cast to check)

[fleet lichen]

That's what am trying to do this whole time

[lunar sleet]

you were using onEndOverlap

do what I said above

[fleet lichen]

Am new to unreal, so i didn't even know something like getOverlappedActors exist

...

[lunar sleet]

Now you know 🙂

[fleet lichen]

Now just figure out how to use it

XD

[pseudo anchor]

guys is there a way to get forward vector of an rotation in world space? or a way to convert it to world space

[fleet lichen]

...ups

[cyan bone]

how does that work? if i make a cylinder that doesnt make boundaries

? or am i missing something

just like you cant just make a cube

you must make 4 boxes to define the cube

[red berry]

How do you call the constructor or begin play from a simple blueprint that extends Object?

[tawdry surge]

Pretty sure objects don't have a begin play function

[red berry]

Then what about a constructor? I know UObject has one, but the blueprint version doesn't? In every other language, every object/class has a constructor, but somehow in unreal it doesn't

[thin panther]

it does, its just not exposed to you iirc

[lunar sleet]

Drag from the array element and cast to your character. Also watch the pinned blueprint communications video in this channel

[red berry]

I'm trying to setup a grid based inventory system like tarkov. A BackpackComponent might have multiple groups, e.g. 1x1, 2x1, etc. I'm trying to use the Object class for each of these groups, so the backpack will have an instance of "BP_StorageTiles" setup with a 1x1 array, and another one with a 2x1 array.
If I don't have access to the constructor for the BP_storageTiles, then how do I setup the size of the array? It makes no sense that I would do it in the BackpackComponent because all it does is manage and look over the groups.
And I've read that maybe Actor is better for serialization or multiplayer stuff than Object? But I don't need a 3d transform for inventory objects

[frigid swallow]

How would I cast an object (lets say gun) to a character's arm?

[fleet lichen]

Like this?

[thin panther]

you wouldn't

you have a fundamental misunderstanding of what a cast is

it's type conversion. checking if a general type is a more specific thing, i.e. "Is this Actor a Gun, if so let me shoot it"

[lunar sleet]

Yep

[fleet lichen]

So now i just connect it to the end of opening the doors?

[devout oak]

Can someone show me how to put this pseudocode into bp? I have tried many ways but just cant seem to understand it. https://i.imgur.com/4S06WNj.png

this is what I have so far https://i.imgur.com/G4Fxj8q.png

[lofty rapids]

are you just using an array of values, or do you need something like an object ".cost" ?

[slender quest]

general question about best practices for Timers, is this really the best and right way to do this? Just type in the name of the function I am trying to call?

[devout oak]

I have multiple orbs with a range of value from 0>1000 and im trying to have it where it shows the highest value above the orb when holding down the "1" key to find the highest

[lofty rapids]

so they all have a variable cost ? or where is this value ?

[devout oak]

so this is the bp for the orb

https://i.imgur.com/4wkqwfu.png

this is the bp for the sidescroll character

https://i.imgur.com/uh9CS7Q.png

[lofty rapids]

ok so a float cost

and that array your looping, it is of all the orbs ? actors ?

[devout oak]

correct

[lofty rapids]

so foreach and out of array items try to get cost

see if that works

just drag out of the array element, and type get cost

hopefully you don't have to cast

[lofty rapids]

Your going to need a variable of type actor to set as the highest

then you loop through checking cost, if it's the higher/lower set that variable to the array element in the loop

[devout oak]

I have a local variable CurHighest set to the BP_Item

[lofty rapids]

ok

so that foreach loop is looping through and you are getting the cost

so you want to check that against the highest

drag out from cost and type >

to get the greater than node

[devout oak]

okay

[lofty rapids]

you need another variable

that is the currentHighest

a float

so you can check against the cost

[devout oak]

Would it be another local variable or a regular variable

[lofty rapids]

you can use local

because it strictly for this function

[warped saddle]

Guys, In widget blueprint, i have description for an item and when i hover over the item i want to display item describtion but i want to dispaly it in some kind of a background, like border or vertical box or whatever, do you now how to do it

?

[devout oak]

https://i.imgur.com/o0KhsHh.png

so like that

[lofty rapids]

ya and for now do a branch that if that is true set the highest cost to that cost variable

[sonic crest]

Isn't there a node that already does that?

[devout oak]

https://i.imgur.com/ZIl08rU.png

[lofty rapids]

well you don't want to return yet you have some stuff to do

out of the true set the HighestCost to the cost value

[sonic crest]

You need to break on true and return that array element

But why not do it in cpp tho?

[lofty rapids]

why would you want to break

[frigid swallow]

Thanks for the clear-up. I guess what I meant to say was, how would I get the gun sprite to be attacked the a character’s hand?

[meager spade]

No, you have to loop through the entire array every time

[sonic crest]

My bad

[devout oak]

Well the value varries so I dont have a set value on each item

[lofty rapids]

you want to set that local variable HighestCost

to the variable you got out of that array element, cost's value

[sonic crest]

Just on true

[devout oak]

so like this

https://i.imgur.com/aZdHVff.png

[meager spade]

And set Cur Highest to the loop element

When it's true

[devout oak]

so i need a 2nd Set CurHighest?

[lofty rapids]

now move that set at the beginning to the end and plug in the array element

[lofty rapids]

well you have a float, and an actor reference

[sonic crest]

Yeah, you don't need to clear it first tho as it'll be replaced anyway

[devout oak]

So get rid of the current set CurHighest and move it to the end?

[lofty rapids]

the first one you can get rid of it's not doing anything or needed

then on completed return it

[meager spade]

Depends on where it's used tbh, is this inside a function then yes

[lofty rapids]

yep

and plug in the array element

[devout oak]

Ive gotten lost somewhere

what do i connect my output on the Set HighestCost to

[lofty rapids]

so what is your code now ?

[devout oak]

https://i.imgur.com/jQSUTVu.png

[lofty rapids]

you don't want to return there

drag out of completed

and return there

or just plug in the exec from complete in the return node

[sonic crest]

On complete

Return on complete

[lofty rapids]

your returning on the first go because your in the "loop body"

or atleast the first true

[devout oak]

https://i.imgur.com/FwbUdiG.png

[lofty rapids]

now you just need to do one more thing

[devout oak]

well its not dragging from the Set CurHighest to the return node

[thin panther]

you can just attach it to the socket :)

[devout oak]

@lofty rapids im not sure what the one thing i need to do is

[lofty rapids]

here you can see the loop body runs for each element and you set the reference to the one that is higher than highest, so it will be the highest on completed

get the ref, and plug it into your output variable

[devout oak]

so use a get node?

[lofty rapids]

ya, you can also just grab the variable from the left and drag it onto the graph, click get

[devout oak]

so like that?

[lofty rapids]

looks legit, give it a go

[devout oak]

doesnt work

[lofty rapids]

is it running ?

or how are you running it ?

[devout oak]

i pushed play

and held the 1 key

[lofty rapids]

so when you push the 1 key it runs this function ?

[devout oak]

oh just kidding

it working

so I would basically do the same thing but instead of the > i would use < for the lowest correct?

[lofty rapids]

yep

make sure you default the lowest to something rediculous high

so that when it runs the first time it's not something like < 0

[devout oak]

So I have the same code for the lowest

changed the variables that I needed but its not showing the lowest

[lofty rapids]

what does it look like ?

[devout oak]

https://i.imgur.com/5UyGeIk.png

[lofty rapids]

what is your LowestCost default value ?

[devout oak]

0.0

[lofty rapids]

theres the problem

[devout oak]

so would i need to change that to 0.01

[lofty rapids]

No change it to something that would be higher than the highest cost value

[devout oak]

so I would want it higher than the max value?

[lofty rapids]

right, think about it if your looping through and checking if the cost is < 0.0

it will never be true

you want the default to be higher than max so that any value works

[devout oak]

okay

i set it to 1000

and that worked

so I just set it to the max value

Ty so much for the help

[frigid swallow]

The thing I’m trying to attack is going to be a pickup-able item. How would I do that with blueprints?

[floral stump]

what are these yellow color interfaces?

when I double click them nothng happened 😄

[limber parcel]

yeah because ure using outdated engine version 🤦‍♂️

[edgy ginkgo]

I am trying to have a game over camera that rotates around the level on a spline so I followed a tutorial but the camera does not move position

anyone have advice?

[zealous moth]

there is a node that returns the world location at a distance on spline

and vice versa

you can get that location

and increment it

[edgy ginkgo]

what would that node be called?

@zealous moth I am having trouble finding that node, is it in 4.3?

[weary imp]

likely this

[weary imp]

so he's saying you could use the node i screenshotted above to determine world locations by incrementing the distance param

[edgy ginkgo]

I guess I am still slightly unsure how to go about that from this number

[weary imp]

basically you could use it to "keyframe" your camera animation if you know the total length of your spline, if im understanding it correctly. however that doesnt necessaryily explain why your camera isnt moving at all with your current setup. let me take another look

[weary imp]

is your "Spawn?" and "End Location" the same point? like a connected circular spline?

[edgy ginkgo]

no they are two different points

I am using these since it seems simpler but they are not moving still

[weary imp]

i think it needs to be on the tick event if you do it this way, im new myself so take it with a grain of salt

[edgy ginkgo]

it is on a tick

[weary imp]

and the end game boolean is staying true?

[edgy ginkgo]

I made sure that is happening and the game tells me it is

currently nothing else is happening on game end

[weary imp]

at this point id do a print string on tick for the "end game?" var and both location return values to at least make sure we're getting something valid

[edgy ginkgo]

I did one after the branch which works

and I did one after the set world location which works

so it is seting the location on tick it's just not a new location

[weary imp]

just for curiosity's sake, what happens when you set interp speed to 0

[edgy ginkgo]

it does not change how things work it spawns the camera at the correct initial point on the spline but does not move

I cranked it up as well with no results

[weary imp]

0 should teleport it straight away, so that helps narrow it down a little

[edgy ginkgo]

is it a camera or spring arm setting I am missing?

[weary imp]

this may not be the overall problem, but i think you need to loop the distance var on the "get location at distance along spline" node and increment it

[edgy ginkgo]

how do I do that? confused by the meaning of that sorry

[weary imp]

otherwise its just always using the beginning of the spline as the current point

lets try this:

so you spawn your camera, get its world location run that to the "current" pin of the vinterp to node

then we just use a single get location along spline node at your desired distance, in this case that would be the length of the spline i think

[edgy ginkgo]

I tried using the spline length as the distance to get the zero to full length but this doesn't fix it

[weary imp]

i think your "current" pin on the vinterp to node is the issue

because youre telling it your cameras current position is always the start point of the spline

which you wouldnt want to be the case as soon as your camera moves, so that pin should be the actual world position of your camera

[edgy ginkgo]

I see that makes sense

let me try that

[weary imp]

good luck!

[edgy ginkgo]

now it does move!

[weary imp]

lets goooo

[edgy ginkgo]

but it only goes one way and stops

[weary imp]

well we're getting somewhere

[edgy ginkgo]

thats huge though

[weary imp]

the next thing is incrementing your distance

because right now youre just sending it to the send

to the end*

so some "x" amount of time you need to give the "get location at distance along spline" node a new distance

so youre basically plotting points along the line, rather than just telling it where the end is

because right now your setworldlocation node doesnt care about your spline at all. youre just telling it where the end of the spline is so its sending the camera over there

the distance variables plots points along the curve and youll interp to those

[white veldt]

is there a fsr3 plugin for ue5? (not mobile)

[remote meteor]

Not yet

Public it is

[dawn gazelle]

Whatever your Get Inventory Manager function is returning is not a valid reference.

[trim matrix]

oh, thanks

[radiant cape]

if i need my ai/player controller to know when OnDamage/PawnSee happened to its controlled pawn... would i use an interface to message to the current controller?

if so, is it practical to send a message from the pawn, to the player controller, and then to the HUD class in that order?

because i need my UI to also know the stats of the currently controlled pawn

[dark drum]

In the controller, you can get the controlled pawn and bind to the on damage events.

Regarding the pawn sense stuff, you can get the pawn sensing component using the get component by class node and bind to the relevant events as needed.

This will prevent the pawn from needing to communicate directly with the controller.

[radiant cape]

THANKS!

best to keep with this listener approach for the controoler/pawns?

[dark drum]

I would say so. It makes swapping stuff out easier. If you make different characters it means you wouldn't need to set the stuff up to communicate with the other stuff.

[radiant cape]

my player camera pawn is just an rts camera, all pawns can be the player or ai so this sounds perfect tbh

[pulsar pulsar]

So i made a fade in effect for my respawn widget but for some reason it keeps applying to the alpha even when it reaches 1,0. I'm confuuuuused.

Sorry, First pic was bad.

Floaty Alpga was just for seeing the value on screen. It does stop on 1,0 but still continues to add to it

[velvet turret]

How to do that?

[agile prism]

Ah I can't quite remember now, but the way most people do it is create another widget bp and then have that display as a dropdown

[dark drum]

In your timeline, adjust the length to match the last key frame or tick the use last key frame option.

[agile prism]

That way you can edit the particular selection boxes within the drop down if you link it to a individual widget bp

[modern radish]

Hey man, sorry to bring this up again, I was hoping you could explain me what you meant, how can I avoid connecting it twice?

[surreal peak]

• Instead of connecting the Event directly, use CreateEvent
• Instead of connecting the TRUE Pin of the BRANCH to the FOR EACH loop, simply call "JsonIngested"

And fwiw, you can also make that Array an Param of the EventDispacher

And pass that along when Calling it

Then your JsonIngested Event already gets the Array

[cyan bone]

https://www.youtube.com/watch?v=gGqeX8gvqeg
Well thats how i handled it.
Dont know if im reinventing the wheel. But its working.

[pulsar pulsar]

I did tick Use Last Keyframe but still the same issue.

[surreal peak]

May I ask why you use a Timeline if you are already in a Widget?

[pulsar pulsar]

Here's a clip of what's happening

[pulsar pulsar]

I couldn't figure out a way to fade in the widget inside the widget itself

[surreal peak]

Given a Timeline is a Component, that also means you are driving it from outside the Widget

[surreal peak]

Widgets have Animations

[pulsar pulsar]

oh

[surreal peak]

You can literally make an Anim where you set the Opacity or whatever over time

[pulsar pulsar]

i will have to look into that

cheers

[surreal peak]

Animations are created via the Designer Tab of the Widget, at the bottom/bottom-left somewhere

Once you made your Anim, you can find the Anim as a Variable in the BP Tab of the Widget under Animation Category of the Varibles List.
You can then drag that out like a normal variable and call Play Animation on it

[modern radish]

Okay, is this what you mean in the first part? Awesome to know, I will try to fetch the Array alongside it

[surreal peak]

No

Gimme a minute, I'm gonna wire it

Takes less time

[modern radish]

Sorry man, really appreciate it, It's confusing to me

[surreal peak]

That's also with the Array being part of the event

[modern radish]

cool, in my case it's a struct, but I can just swap it

should I pass as reference?

[surreal peak]

Yeah that part was offscreen on your screenshot

When you click on the Event Dispatcher in the GameInstance, you can add Inputs with the + at the top right

I used a random Struct type, so just ignore that.

[modern radish]

sure, yeah. I got that working.. but what is confusing to me is thy does it look like it's an Input when I call it on the second BP? I would have expected it to be on the right side, coming out as output?

here is my logic in the Game Instance BP, where I parse the JSON

(will rename things later)

[surreal peak]

Not sure what you mean with the question. Where do you expect it to be an Output?

[modern radish]

ahh okay, I think I understand now, it appears as output in the Custom Event

[surreal peak]

You sure?

There are no outputs involved here

@modern radish

[modern radish]

I just thought when you told me I could pass my data with the Event Dispatcher, I thought it would look different, but I think I understand now

[versed fulcrum]

Does anyone knows why i can't delete the StaticMesh inside a Blueprint?

[surreal peak]

EventDispatchers/Delegates are Lists/Arrays of who to notify when Calling/Broadcasting it.

In C++ the EventDispatcher is just a Variable. The BPs its a bit more fluffed out with custom nodes.

The Variable, internally, has an Array of who to notify and how. E.g.

[0] Object1, MyCoolFunction(Param)
[1] Object2, SomeOtherFunctionName(Param)

With "BindEvent", you add an entry to that List. You can also unbind it if you wish to no longer be notified. Binding multiple times is also possible, so it's wise to unbind after you are done with whatever you had to do.

For you that would be

[0] YourObject, OnJsonIngested(STData JSONDATA)

When Calling/Broadcasting the EventDispatcher/Delegate, it will go over the list and simply call those functions on those objects, passing in the Parameter.

The list of Parameters on the Function you bind has to match the signature (Inputs) of the Delegate. In C++ there are some more options available, but that's the gist of it in BPs.

So your OnJsonIngested function just has an Input. There is no Outputs involved here.

[surreal peak]

Pressing Delete on your Keyboard also doesn't help?

[versed fulcrum]

no work.. what i did is just copied a static mesh from anther actor in the level

and pasted into the bp

[surreal peak]

Have you compiled and saved the BP already?

[versed fulcrum]

yeah

[surreal peak]

Hm, can you try restarting the Editor?

[versed fulcrum]

yes, thanks

hmm. seems still won't be able to delete. I found this, but these static mesh are just inheriting the StaicMeshActor class, not a BP

[edgy ginkgo]

I have a spawner that is supposed to alternate between two types of trees, only one of them is spawning, even if I just have it spawn the second one it spawns the first one

they aren't even in the same class

[surreal peak]

Hm sorry not sure then. Either a bug or something obvious that is missed :<

[versed fulcrum]

OK，thx man

[surreal peak]

If it spawns the first one even if you only connect the second one, then your issue lies somewhere totally else :P

[edgy ginkgo]

that's true I suppose I am confused where

oh Im dumb

nvm found it

[dark drum]

what advantages do data assets have over just using a uobject?

[remote meteor]

Asset registry

I think

[dark drum]

i'm doing a bit of work on my dialogue system to add audio and montage support and currently debating on making the selections their own object of sorts for the data. (Dialogue, Audio, Montage and ResponseOptions) Not sure if I should even bother and if I do, if I should just use a uobject (I can just get the default values from the class) or use a data asset for it.

[cursive cloud]

When I kill the NPC he ragdolls and dies (good) but an invisble version of him appears and will follow me when im in radius and attacks me:
Im not sure what im doing wrong

when I shoot at him I see the blood particles as well but it doesn't die its an invisble god

[dark drum]

That would be the capsule component that the mesh would be attached too (before you ragdoll). When the NPC dies, you need to stop any behavior they might have if using a Behavior tree.

[remote meteor]

a data asset is also an uobject

what you could do with an uobject you also can do the same on data asset

[dark drum]

Yea, im not sure if there's much point the more i think about it. If a conversation has 7 pieces of dialogue, then that would be 7 uobjects/dataassets that would need to be created. If there's 100 different conversations, that could be around 700 uobjects/dataassets that would need to be created. Just thinking about naming them gives me a headache haha.

Hmmm...

[remote meteor]

oh definitely not an object for each sentence

😅

i would do an object for each conversation..

[dark drum]

It would be the back and forth so not always a single sentence but it is still a lot haha.

[remote meteor]

until the day epic decides to finish up CommonConversation into a more robust backbone 🫠

[tawny summit]

Just a question, is there a cloak spell effect equivalent in eu5's blueprints like how the creation kit has one. What I mean by this is can you put a cloak effect on an actor (the effect can be anything) that would cause an effect on other npcs or the player if they get too close to its radius?

[dark drum]

If there was a way to have the function update the number of output pins based on the inputted uobject/dataasset, that would be pretty cool.

[thin panther]

No. The creation kit was designed with modding a specific few games. Unreal Engine is a general purpose engine. You would have to make this, most effectively with GAS

[tawdry surge]

@remote meteor more robust? Last I looked it doesn't even function

[minor dew]

I've set a default player pawn in the project settings, and the player controller that I created.
When I start the game, the controller doesn't set the view target to the camera of the player pawn, instead it put a camera in the mesh location.
What's the problem here? 🤔

[undone sequoia]

guys when I have output from pitch lets say -180 min and max 180 degrees and I want make from it min -45 max + 45 so output will be between these range what to use ? i tried clamp and put there -45 and 45 but its not working its giving me always 45 lol

[remote meteor]

supposingly they use it for fortnite, but they strip like 99% of it and ship it as a experimental plugin 😅

i somehow manage to get it "working", its very particular of needing the game feature plugin for its content...

i just liked the behavior tree alike editing

the other things,, not so much..

[tawdry surge]

I looked at the c++ for it a few months ago, and you couldn't do anything beyond assign a speaker and feed it a line. Most of the nodes didn't actually do anything and it didn't implement any of data arguments for dynamic conversations.
Didn't look like they touched in in months either.
Was just gonna steal the graph and roll my own

[random solar]

Got an issue I need help understanding, I'm trying to cast to a widget from the character blueprint. The issue is that the cast is failing when I create a user widget object reference when I put it in the object pin.

The only blueprints for the actual widget is me making a reference to the character from the widget.

[dark drum]

It looks like you've not provided the object ref it should be casting.

[random solar]

In place of that would be a variable that is the user widget object reference that causes the cast to fail

[dark drum]

With there being the yellow warning message, I would assume the object your plugging in can never be what your trying to cast it to.

[random solar]

My bad, didn't press compile but issue still applies

[dark drum]

how do you set the ref?

[random solar]

That's what I'm trying to find out. All the widgets are host on another blueprint called MainHUD. MainHUD is created in playercontroller and calls the HUD with all it's widgets in the second picture

So I don't think I have created a reference to the widget individually

If you think what ive explained is false then I will continue to look for it

[edgy ginkgo]

for some reason this is not adding +1 to the interger

[trim matrix]

hello guys, I have a problem with my blueprint.

everything works visually fine with 5s delay, but if I clicked twice sounds keep playing after 5s and giving this error

[north lynx]

Hi!
I have a question
I'm currently working on picking and dropping system, but I hit the wall
Using Interact Interface and the trail from players view idk how to know, which item to show the player
Every tutorial uses the collisions to pick the items, but I don't want another system for only picking and dropping items.
Idk what to do...

[modern radish]

That’s super helpful, man. Thanks so much again for your help, really appreciated!

[north lynx]

Idk if it will help, but you can add "Is Valid" node after the "Cast to..." node, like this

[trim matrix]

like this ?

[dark drum]

The 'isvalid' node after the cast is redundant, if it's not valid, the cast would fail anyway.

[golden pewter]

how can i prevent a widget from blocking an actor in my level?

[trim matrix]

yes it didn't work /:

[dark drum]

This issue is your stop audio node. It's pulling an input from a different execution line (which you should avoid). When you add an audio component, store it in a ref and when you go to stop, use the ref.

[trim matrix]

you're right, thank you. how can I add ref here to stop it

[dark drum]

pull from the retun value on the Add Audio Component and promote to variable. Then use this variable at the target for the stop audio node.

[trim matrix]

didn't work 😦

[dark drum]

On the topic of event dispatchers. Do you know (of the top of your head) if a UObject that has bound to an event somewhere will be garbarge collected if the UObject is no longer referenced?

I would assume, the binding would keep it loaded right?

[dark drum]

You need the set node to be on the same exec path as the add audio component. (Between the add and play nodes)

[edgy ginkgo]

I am so confused by this variable

for some reason it would add the plus 1

[dark drum]

whats the issue? If there's an error, you need to show it.

[dark drum]

hit the recompile button

[edgy ginkgo]

nvm for my issue

[dark drum]

Does the cast fail?

[trim matrix]

same error

[dark drum]

What var type is 'NewVar'?

[trim matrix]

just promote variable, didn't name it

[dark drum]

You need something like this.

[trim matrix]

system sound didn't recorded but after second click sounds keep playing

[dark drum]

your not setting the var thats connected to the stop node. You should set this to the audio component you create when you create it.

[thin panther]

why are you adding an audio component each time you interact? 🤔

[split sleet]

Hi, I've been trying to create a seesaw that trying to stay horizontal like in Fall Guys and for some reason Angular Motor stops at some point as shown in video (34-35 second). All I did was:

1. Create Actor Blueprint and add Cube
2. Set scale of the Cube to 4,25 on X and 0,5 on Z
3. Set the Cube to simulate physics
4. Add a Physics Constraint to the Cube
5. Set the Component Name 1 in the Physics Constraint to "Cube"
6. Lock Swing 1 Motion and Twist Motion, limit Swing 2 Motion to 70
7. Change Angular Drive Mode to Twist and Swing and check Swing in Drives and set Strength to 1

I tried:

• changing limit angle, component names and blueprint hierarchy attaching physics constraint to root component instead of cube;
• delete and add constraints again;
• reopen project; create new blueprint;
• use swing 1 motion and twist motion;
• change stiffness and damping;
• change angular motor strength;

I've noticed that it mostly happens when one side is slowly going upwards

[dark drum]

Just helping Boraniks, one step at a time lol. But yes, ideally, he should either add in via the editor (setting the sound) or add it on begin play and reuse the same component.

[trim matrix]

lol now this happening because of delay

[dark drum]

Make is so the play node doesn't go into the timeline. That would just make it restart after 5 seconds.

[trim matrix]

but you did here

now I disconnect play

but still coming sound after 5 second when I click twice

[civic citrus]

I wanted to create a very simple actor for representing cover (basically a mesh, collider, a variable indicating whether it's weak/low or strong/high cover, and a variable representing its durability). It's easy to toss these together in a blueprint, but apparently then I can't access the cover level and durability from C++ code? Is there a way to get around that? If not, what's the proper way to handle this situation?

[dark drum]

Move the add component to begin play and then add an event track to your timeline at the 5 second mark. That way, it'll only play the sound when it gets to that point. If it's stopped before that, it won't play.

[surreal peak]

Kinda sure that's a weakobjptr

[dark drum]

so it would get garbage collected?

[surreal peak]

Pretty sure yeah

[dark drum]

one less thing for me to worry about then haha.

[trim matrix]

how did you add play audio there ?

[dark drum]

add an event track inside the timeline, similar to how you add a float track.

[trim matrix]

now sound is always playing from start :/

I unchecked the auto activate, so now not starting on itself but it playing when I clicked

not after 5 sec

[frigid swallow]

How would I attach an actor to my player character’s arms using blueprints?

[north lynx]

Any ideas about that?

[lofty rapids]

is it falling at all? or are you just destroy actor it looks like it disappears

[thin panther]

you just use the attach actor to component node.

[random solar]

Anyone able to help with my issue? I'm available to show off my blueprints with screenshare too

[thin panther]

how could we possibly know? you havent shown us anything other than a video?

[split sleet]

So I find out that it happens when angular velocity gets to 0. But I still have no idea why it's stops angular motor when velocity is 0

[split sleet]

I find kind of solution - just add impulse every time angular velocity reaches 0

[pulsar pulsar]

I have now implemented this but I'm still having the same issue lol. I'm trying to figure out what's causing it though

Ah, it's happening without the animation aswell. So the issue lies somewhere where the sun doesn't shine it seems.

ah

i know now i think

The widget creation is being called each tick

yup that was it

[frigid swallow]

So I changed the mesh for the player character that's referenced here, and now I can't figure out what to put for "Parent" and "Rocket Name".

[near tundra]

How do I make it where a projectile will not collide with itself but still collides with other objects?

[lofty rapids]

are you handling the collision yourself or is it some sort of physics stuff ?

if your handling it yourself then just cast and do nothing, run the code on fail

[manic hamlet]

How do you guys tell your UI elements(i take Crafting menu as example) what the player is ? do you always "Get player character->Cast to PlayerCharacter"? or do you have a variable called like "PlayerCharacter" in your CraftingMenu ? is there a "best practice" for this?

[near tundra]

I'm using generate overlap events on each object

i figured it out

I had generate overlap events on the arrow itself

-facepalm-

[lunar sleet]

Make a custom collision channel

If you want to block only a specific type of object

[lunar sleet]

You can cache and reuse a ref just don’t start doing actual logic in your widgets

[zealous moth]

I get player character and cast to it. There is nothing of value lost. The character is already in memory, you're just getting it.

[cold junco]

hello ,noob here , i have build a pressure plate , and put a cube on it , when i move it with my character on the plate , it does not stay in the state open (end overlap for the cube ) , i have try "is overlapping" to tell the pressure plate that i m still here , don't know what to do for the door to stay open if my character stay on the plate .

[manic hamlet]

I know about the references 🙂

Lemme explain my scenario:
Every UI usually needs variables or functions from the "root player":

• Clicking Craft in a crafting Menu needs a reference to the InventoryArray to add whatever is crafted to that variable.
• Clicking "Increase Stamina by 5points" in a Talent-Tree would also need a reference to the player as the Stamina Variable is there.

My thought was:
Do I give the Crafting menu and the Talent Menu widget both a PlayerCharacterRef variable that these buttons(Craft/IncreaseStamina) then refer to and get the functions from the player that way or do i do this(screenshot) each time I click the Button:

[lunar sleet]

For starters don’t use == or != for this

Drag from other actor and cast to the BP you want to check for

It’ll give you an execution and a cast failed

[manic hamlet]

See my comment above, just in case 😄

[lunar sleet]

Do you have to make these calls from more than one spot in each widget?

[manic hamlet]

I hope I get you right:
Yes, there is more than ONE crafting button and more than one Talent in a talent tree 😄

[lunar sleet]

Well yeah but they’re all the same blueprint or children of it right?

[manic hamlet]

I think the answer to that question is also yes.
e.g.:
I got a WB_TalentTree
and theres like 50 WB_Talent
in there

[lunar sleet]

That’s fine

So you should only need to get the char once and cast into it

At which point there’s no need to further save that ref

Basically, just get it and cast. I’d only recommend saving the ref if you have to reuse it several times in the WB

[sick fable]

Can I get help I am trying to get this audio to loop while the event is triggered

until it end

s

[lunar sleet]

Use the edit button

[sick fable]

I am not sure how so I didn't do it

[manic hamlet]

the thing is im trying to figure out if a reference makes sense even if i need it multiple times, as the child (the Craft Button) would need a reference to the parent each time anyway

[sick fable]

if you mean set it to loop in the file If I do that the event keeps getting called quicker than the sound can end

[manic hamlet]

imma prepare something, gimma 5min

[lunar sleet]

I meant edit on discord

[sick fable]

I need the sound to end when the even is called

oh

bru

[lunar sleet]

So you don’t have to add 1 letter 😀

[sick fable]

do you know how to help me

[lunar sleet]

You want to ask this stuff in #audio

[sick fable]

ok

[manic hamlet]

@lunar sleet @zealous moth
1screen: WB_CraftingUI
2screen: WB_CraftingItem

The WB_CraftingUI has a "foreach RecipeYouHaveLearned"(not real names,just making sure you understand what i mean xD) in it.
Now the Craft button doesnt know what the player is, and I have figure out 2 solutions to this problem:

Nr 1. Inside of WB_CraftingItem I do a GetPlayerCharacter->Cast to BP_PlayerCharacter and from there i do stuff like AddItemToInventory

The second solution would be: WB_CraftingUI has a variable of type BP_PlayerCharacter and inside the foreach I give the Child(Wich also has a variable called "Parent", Wich is the WB_CraftingUI, and then once i click the craft button it goes to: Parent->BP_PlayerCharacter->AddItemToInventory

My question basically is(as I am used to avoid "Cast to" wherver I can): Is it better to have that "layering" of variables in Example 2 or is it better to "Cast to BP_PlayerCharacter" EACH TIME a player clicks craft?

[lunar sleet]

Is it single player?

[manic hamlet]

No

[lunar sleet]

For #2, if you mean create a variable and select that BP, absolutely not lol

Show where it’s fired

[manic hamlet]

So casting each time would be the way to go?

[lunar sleet]

Also whoever told you to avoid casting is terrible at this, don’t listen to them

[lunar sleet]

Yes, don’t fear the cast

[manic hamlet]

self taught 😄 so some random youtube video many moons ago haha

[lunar sleet]

You say each time but really you only do this once, right?

Like once per widget

[manic hamlet]

Once per click on something UI related that needs player data

idk, you know PoE?

[lunar sleet]

Interp will change the value but it won’t call your entire function again, print the output value if you need to understand better

[lunar sleet]

Yeah that’s fine

Don’t worry about that. Lot of plebs making YouTube tutorials that have no clue what they’re doing and just saying random shit to get views. The tiny cost of casting is unlikely to ever be an issue in your game

[manic hamlet]

e.g. lets say i got 20 Talent points and all my talents would be:
4Buttons of 5+ Strength
4Buttons of 5+ Stamina
4Buttons of 5+ Dexterity
etc

so each of those buttons would do a "GetPlayerCharacter->Cast to BP_PlayerCharacter->IncreaseStats()

[lunar sleet]

Basically your interp starts but you’re only showing the value in that next tick

You’d need a timeline or like @edgy ingot said, on tick or a timer by event

[lunar sleet]

All of these buttons are in the same widget bp?

[manic hamlet]

UI_TalentTree
yes

[lunar sleet]

Yeah, so make one function

That gets the char and casts

And then call that function on each onClicked

So you don’t have to write it 50 times 😀

[manic hamlet]

well all these buttons derive from the same parent anyway,so i kinda got that already

[lunar sleet]

Ok good

Then no problem ? 🙂

[manic hamlet]

I just,until i realized that this is getting messy and then i came here to ask about it 20mins ago^^, did it the "parent way" as in:
I have a foreach->CreateTalentPointWidget
then each TalentPointWidget has a variable type UI_TalentTree and the TalenTree has the ref to the player so each time a player clicks it goes to the TalentPointWidget->GetParent(now were in UI_TalentTree)->Get Player Ref->IncreaseStats()

I was just realizing if i have like 200 talent points in the tree that would mean I have 200 of the same variable attached to them for no reason, wich i can easily solve by just casting to the playerCharacter

[lunar sleet]

Did you plug that into a tick or what

Yeah no don’t do that

I’ll explain how it works in layman terms

Interp changes a value over time

If you want to reflect that, you need to check that value several times during that time

So

try this

On clicked, set timer by event, set it to looping

Make a new custom event

Put your code in it

Delegate that event into your timer by event’s event in pin

Also add a branch to check if that value has reached the end of your interp

When it does, clear and invalidate the timer by handle

[lunar sleet]

...

why are you calling the event instead of calling the timer?

after this, you need to google set timer by event @odd berry

here's a mockup above, might need testing

[jolly cipher]

Hello!

This maybe a noob question, but im trying to add a mount system in this template. ( First time, trying to wrap my head around this ).

I created a separate blueprint for my mount actor. Created a overlap event so when the BP_PlayerCharacter overlaps, the player would attach to the mount and posses it.

After testing a very basic setup, as soon as I posses the mount I start getting spammed that it can no longer find the player's dependencies components.

Is there a way to attach the mount to my character without having to loose all my depencies of my main player?

The only way I would see maybe working would be to create a bool (IsMounted) for my animBP and create a blendspace for my mounted animation but I have no clue how to make my mount move and have it controlled by player or mirror its direction ... Does anyone have any tips or tricks to go around this?

[lunar sleet]

think of a timer by event as your own personal tick with customizable interval and that can be stopped

sec, gotta do some actual testing on it

this'd be much easier with a timeline but can't use those in widgets apparently

[pulsar pulsar]

so I made my project a C++ project because I thought I would learn C++ but I've kinda changed my mind as C++ is so darn messy to look at lol. I kinda want to change my project into Blueprint again but I'm afraid of what/or if I could lose stuff in the process.

[thin panther]

No need. You can still use bp

And still not write any c++ in a c++ project

But I have no clue what you mean. Unreal c++ is much cleaner than BP 😆

[pulsar pulsar]

I figured as much. But I think the basic stuff of the movement code for the ThirdPerson blueprint is all located in C++ form.

[thin panther]

You can still very much use the BP content pack

[pulsar pulsar]

As I'm only familiar with C# since before the Unity disaster, I find C++ to be horrendous for the eyes.

[thin panther]

You'll want to get used to c++. BP can't do everything, and you'll want some c++ in a game you plan to ship

[pulsar pulsar]

I'm not able to access some blueprint nodes it seems with a C++ project. Before I made the C++ project I had a blueprint project and I had Input stuff in the TPC BP but with the C++ project the TPC BP does not have these standard nodes

[pulsar pulsar]

I'm not really looking to do so atm. I want to world/level build and just create small things within them to build a portfolio. Hence why i feel BP would be easier to have for this

because I was following a tutorial on implementing swimming as I had no clue where to start so that's when I noticed my BP being different. So I drew my conclusion it was because of my C++ made project

[lunar sleet]

k, sry that took so long, had to work around not being able to use Timelines in widgets

you can adjust the update rate by changing the Time

sry I missed a step, sec

there, fixed

do you see kind of what this does, or do you want me to take you through it

so onClicked you set a new timer that "ticks" every <Time> seconds. Every time it "ticks" it calls that CustomEvent. That event lerps between value A and B which would be your start float and target float. If you hover over the Alpha it'll tell you 0% is A and 100% is B. Then from there you can plug that value into your Set Render Scale. Once the value's hit the max amount you give it, you stop the timer by clearing and invalidating its handle

[cold junco]

Thank you ! , did not help for my problem but still useful to know ^^ , here is what fix my problem

[lunar sleet]

Are you having actual perf issues?

you'd need to do some #profiling probably and maybe simulate it for mobile devices since those usually have less resources

[jolly cipher]

Im rethinking my approach. Im trying to see if theres a way to attach my main character to my mount but instead of possessing it have the mount mirror input from main character via Tick.
For example in my mount I would capture the MOveForward, MoveRight and Jump inputs from my MainCharacter. This way I would still be able to maintain my main character inputs and components
Would this make sense to anyone? Not sure if I have the right approach to this.

[lunar sleet]

that's not a good idea

[lunar sleet]

open the actual Message Log and click on where it's saying you're accessing None then show that code in a screenshot

yep

you can make them all floats, change the A and B around, and just change the Alpha to a negative value

I just put static values in there but yours can be cached in floats and changed as needed

[versed sun]

Does anyone else get a bug once and a while where you can't delete/cut/copy/paste/duplicate nodes?

everything is compiled , saved

[lunar sleet]

idk much about that #niagara might

[stable crystal]

Hi,

I recently tried to set up movement for a character but it isn't working. I copied exactly what's on the 3D character demo but it isn't doing anything. The block still won't move.

Custom Character Blueprint Class: https://imgur.com/a/ZnLRrMQ

Custom Game Mode: https://imgur.com/a/mVoBEFV

Custom Mapping: https://imgur.com/a/usAiI9W

InputAction Jump: Set as Digital (bool) InputAction Move: Set as Axis2D (Vector2D) InputAction Look: Set as Axis2D (Vector2D)

I know it's not very helpful to be viewing it all from screenshots but any help is appriciated. It's exactly the same system on the 3rd person baseplate level on the unreal launcher. I just copied stuff over manually

[lofty rapids]

well for one thing your ia_move isn't connected in the exec, it doesn't have any execution comming out of it

from triggered into the first add movement
also the add movement input at the end of your ia_look isn't necessary i don't think it's even doing anything

[versed sun]

Here is what I forget 90% of the time:

[lofty rapids]

is the mouse look working ?

[stable crystal]

No, nothing currently. It just sits there

[stable crystal]

Nice catch, thank you. Fixed that

[lofty rapids]

make sure you select the context in the add context

[stable crystal]

Yeah I didn't know if that was needed but I shall remove. I don't think it does anything either

[stable crystal]

Aha! Thank you. That got it working

Now I just need to see if I can smooth rotation because it's a bit choppy

[jolly cipher]

Hello!

So trying to wrap my head about creating a mounting system. I am currently building a shooter game and wanted to add a simple horse mount where you can still shoot while riding.

After looking at a few tutorials on youtube, i'm understnading the the fundamental system revolves around Attaching my main character to the mount character. I would then posses the Mount character to control it.

If im understanding this correctly, once I posses my mount character, I loose all my Main character's inputs and refs.

I assume I need to re-create all my inputs and rework some of my main character refs as most of my HUD ( Behind Tick events ) were based on Get Owning player. Once I posses the Mount character, my get owning player becomes the Mount and breaks alot of this logic ...

I could copy and paste my widgets over to the mount and rework my logics to swtich owning player base if player is mounted or not but just seems like there should be a better way.

Is there no alternatives to attach my main character to the mount but not posses it and still control the mount somehow? Im super confused lol

[stable crystal]

Actually it's not even rotation. It's moving left/right that's choppy. When I press the key there's about a 0.5 delay which causes it to jump in position. Same with going backwards

[frigid swallow]

How would I change the character’s animation/movement using blueprints? For example, when the player character is holding a gun, instead of running like normal, the arm that’s holding the gun stays still?

[oak fable]

hey there
i just bought this asset pack its the procedural turn in place
im having issue with the turn in place component it has many errors but what i need help with is this Steps structure array
it says Steps no longer exists on node calculate tun in place steps but its there
any clue why ?

also inside the function calculate turnInPlaceSteps i see this errors

[lofty rapids]

why does the second add to array have a different setup than the first ?

[oak fable]

i dont really know im trying to fix this asset

[stable crystal]

If anyone has any ideas on how to do this with all the info I've given, please let me know!! Struggling to work it out

[lofty rapids]

maybe #enhanced-input-system would know, sounds odd

[stable crystal]

Yeah. I'll try there. Thank you!

[lofty rapids]

what does it say when you hover over the error on one of the adds ?

[lofty rapids]

try to "refresh node"

[oak fable]

removed them

[lofty rapids]

your array has structures ?

you changed it somehow ?

[oak fable]

its not mine im trying to fegure out how its working and fix it

[oak fable]

no it the same as i imported it

[lofty rapids]

well theres a problem with that array obviously, something with the structure most likely

[oak fable]

okay wait a sec

[oak fable]

that the struc i believe

[lofty rapids]

what happens if you try to drag off the array now and re add the adds ?

or just try to drag out make an add see what happens

[oak fable]

for the duration it says float is not compatible with structure

[lofty rapids]

it says that when you try to drag into duration a float ?

[lofty rapids]

that probably means your dragging the wrong thing into it ?

[oak fable]

when i drag from duration to add

[lofty rapids]

i mean when you drag out and do an add, it shows up with no error ?

[oak fable]

i can join a voice channel and screen share for you if you want

[lofty rapids]

i just help in here sometimes in dm

[oak fable]

yeah from the local steps no error

[lofty rapids]

what are you dragging into duration ?

[oak fable]

its okay i mean so you can have better view

[versed sun]

Oh, you have to Split the Structs

[lofty rapids]

based of this picture you should e draggin the step duration output into there

[lofty rapids]

oh i c you were trying to plug it into the whole thing

[versed sun]

Copy/Pasting Split structs does that

[lofty rapids]

well that makes no sense it's still two different adds

i mean they have a different setup on each on, is this when you drag a new add node ?

[oak fable]

i didnt copy past any thing XD

[lofty rapids]

drag out from local steps and add a new "add" node, it should be the current setup

[oak fable]

when i drag new add node there nothing on it and i cant add anything to it

[lofty rapids]

hmm

haven't work much with structs, still new to unreal as well

[oak fable]

also local_steps looks like that in the local variables

[oak fable]

yeb me too

[lofty rapids]

where it says local_steps, are you sure your structure is selected and it's an array

weird it just shows the colored dot thing by itself

[oak fable]

i see now it was the local steps issue its bugged i added new one and now got the values

[modern radish]

if I spawn blueprints containing actors at runtime, I see them in the Outliner but I don't see them in editor.. Is there a way to make them visible?

[frigid swallow]

How would I change the character’s animation/movement using blueprints? For example, when the player character is holding a gun, instead of running like normal, the arm that’s holding the gun stays still?

[lofty rapids]

well your spawning them at runtime so they'll never be in the editor

[lunar sleet]

Well the 0 to 10 was an example

You need to plug in your actual values

Also

Don’t do 0.001 on the Time

That’s just how often to update

The lowest you should maybe do is 0.1

The values in your lerp should literally be your current scale value and the desired scale value (A and B respectively)

So 1.5?

Did you change A to 1 and B to 1.5?

Yeah cause your counter is too small

You set your float scale to something ridiculously small like 0.0001

It’s going to take forever to reach 1.5

Make sure to adjust your >= too as well

[oak fable]

i dont really know what is the issue with this structure
can't we no longer use the break node or let say how can i break this structure
im really stuck here

[lunar sleet]

Is it a bp struct?

[oak fable]

yeah it is

or i think it is i dont really know im just lost now 🙂

[lofty rapids]

it looks like it

[oak fable]

i can't see any break struct when i drage from the Get node

[lunar sleet]

Prly cause you’re getting a copy, but either way bp structs are bad

[oak fable]

i dont know but here i can't find any break nodes is that normal ?

[lofty rapids]

no it's not normal if it's an array of structures, i just tried it and i can break it off a get

[oak fable]

can you sent a screenshot please

[modern radish]

I understand, but I do see them in the world outliner, hence the confusion

[lofty rapids]

right so i believe the outliner is live so you can see them during runtime

[oak fable]

still cant find it

[lofty rapids]

what does your array variable details look like ?

[lofty rapids]

this window on your variable

[oak fable]

its there and i used it
