blueprint

[lofty rapids]

execution ftw

[gentle urchin]

white thing -> Execution wire

[pearl lagoon]

Well that fixed the number not showing up

Now just the name

[gentle urchin]

without it, the code does not run

[tiny monolith]

how to create a timeline in widget

[hasty merlin]

is this what youre talkign about? found a YT vid about interfaces, he added 2 fucntions, on interact and interactable

[lofty rapids]

you use this function at some point to display the name ?

[tiny monolith]

how to create a timeline in widget

[gentle urchin]

patience

Widgets dont support timelines

[gentle urchin]

There's no get function here

open your interface

add a new function

which returns a text value

then call that 🙂

implement it in the target blueprints

[tiny monolith]

how do I create this

[hasty merlin]

cant you do a sequence for a widget to have one say fade to black?

[gentle urchin]

Animation, yes

[undone bluff]

widget equivalent of timelines is animations

[gentle urchin]

hardly equivalent 🥲

[tiny monolith]

how to play the code I wrote in the animation I want to increase a transform scale value over time

[undone bluff]

I'd say so, though feature set certainly differs

[tiny monolith]

I couldn't find a tutorial video etc.

is best bro glkhfgkhlşfhlk

[undone bluff]

use the window tab to show the animation window first

[cedar spoke]

Hey, I'm looking to spawn a BP on top of another BP. The problem is that the pivot point is in the center and I need to get the vector of the "bottom" of the spawned actor to align. What would be the "unreal way" of accomplishing that?

[tiny monolith]

yes

later

[gentle urchin]

get bounds

[cedar spoke]

Oooh awesome, thanks!

I thought about very overengineered solutions, I'm glad i asked here 😄

[tiny monolith]

how to increase the scale size of something in widget animation

[lofty rapids]

is this not working ?

[frosty heron]

@tiny monolith you can use widget timeline to replace timeline

[frosty heron]

This is not right, you need to use widget animation

Go to designer tab, add anim and do it there

[undone bluff]

https://dev.epicgames.com/documentation/en-us/unreal-engine/animating-umg-widgets-in-unreal-engine?application_version=5.3

[frosty heron]

Any widget anim video would go over it

[tiny monolith]

yes

[narrow pendant]

very confused question here

I'm doing a linetrace and checking for object type. why might this return false?

[undone bluff]

complaining about lack of tutorials when there's documentation 😌

[lofty rapids]

what is the print string showing ?

[frosty heron]

Tbh I find it hard to believe if I couldn't find a tutorial about animating a button

It should be on the top of the page

[narrow pendant]

(I clicked multiple times hence multiple prints)

[tiny monolith]

ah thanks guys

[frosty heron]

Check the class type then

Not an instance

[narrow pendant]

that would be Actor for the base class right?

can't I do a more specific check?

[undone bluff]

== should work like the c++ IsA afaik

[frosty heron]

Depends, don't you make a bp for your sound object?

[undone bluff]

I think this should work

[frosty heron]

It will be w.e the class of your bp sound base class is

[narrow pendant]

oh damn I confused parent class for the actuall class I think

[tiny monolith]

do I need to set this for each button or is it a subwidget

[hasty merlin]

yo cold, im trying out interfaces, for what im trying to do with a door that has 2 widgets (open/close), a chest with 1 widget, and a torch with 2 widgets (turnon/extinguish) this is how my fucntions should look right?

[frosty heron]

Indeed, I mean your sound class is of type actor, but you can go lower and check your bp class u create instead

[frosty heron]

I don't guide on system

Make simple interface, override function. Get a string from it

[tiny monolith]

should I make a subwidget that will have widget button animations everywhere

[narrow pendant]

yeah was being silly. thanks gonna check by class then

[frosty heron]

Once u can do that u can move on

[frosty heron]

Or just cast

[narrow pendant]

fair

[undone bluff]

yes

[tiny monolith]

too much casting bloats memory

[frosty heron]

Only applies to bp

[undone bluff]

this is already a hard reference

[frosty heron]

It's not the cast anyway

But the hard ref

[tiny monolith]

When using a subwidget in another widget, can I access the text inside the button in the subwidget?

[frosty heron]

U should cast to base class when ever possible

[frosty heron]

U can access anything, just need the ref to the instance

Get mywidget->get MywidgetButton -> do X

[undone bluff]

you can preconstruct the text from a variable

[tiny monolith]

oh yesss

thanks

[dry sleet]

Dunno if you've figured it out, but I believe this is the relevant setting

[pearl lagoon]

I still can't figure this out

Can someone explain it to me?

[tiny monolith]

how to put the subwidget button in an interface vertical horizonal canvas etc.

[dry sleet]

(constraints -> XYPlane)

[gentle urchin]

Doesnt really work

Not sure if it used to work, but certainly brings trouble these days

[hoary junco]

I managed to find a solution in the end, I had to use a physics constraint component

[dry sleet]

that probably works, too

I don't know if either solution is better than the other

[undone bluff]

no, you're right

[gentle urchin]

you dont need "IsInteractable"
you want

• OnInteract
• GetInteractionText(or Data)

[undone bluff]

this would work instead

[hasty merlin]

what is the get interaction text/data for? ist hat for widget?

[cedar spoke]

IsInteractable might be useful if you want to have a logic to disable the interaction (like the door is locked)

[hoary junco]

well the linear and angular dampening, they still allow movement but just put a sort of speed limit on how fast that movement occurs, the physics constaint system allows you to completely lock up certain aspects of movement and it's working great

[dry sleet]

yes, the thing I wanted to show in that screenshot wasn't linear dampening but

[cedar spoke]

I do have similar thing in my code to display the text, like "Open the door" when looking at the door but if you don't need something like this you can omit that

[hasty merlin]

i need exactly that

[gentle urchin]

its there to supply the widget with the data needed to show what the interaction does

[hoary junco]

yeah that wasn't working on mine... idk if it's because I was moving the object via a physics handle or what but it just refused to do anything.

[gentle urchin]

exactly this

[dry sleet]

huh

[pearl lagoon]

Nevermind im just dumb

[dry sleet]

pretty sure we use physics handle too and it works just fine

[pearl lagoon]

The name wasn't showing up because I never set it

[dry sleet]

well, unreal works in mysterious ways

if it works it works!

[hasty merlin]

i need an OpenDoor and CloseDoor for doors and extinguish/turn on for torches

[hoary junco]

🤷‍♂️ just one of those things I guess

[gentle urchin]

https://tenor.com/view/stepbrothers-dont-touch-it-gif-13892029

[gentle urchin]

Thats the interaction otext.

you return interaction text based on the state of the interactable object

[hasty merlin]

okay how do i make it know what widget i need?

oh

[gentle urchin]

https://tenor.com/view/light-andre3000-andrélauren-benjamin-ms-jackson-song-bulb-gif-18917817

[hasty merlin]

so in the door bp, event GetInteractionData -> if doorclosevar == true -> createwidget opendoor

[gentle urchin]

I wouldnt create widget

i would simply r eturn the text the existing widget should display

hopefully the widget is owned by the player who's gonna see it

and exist somewhere in their context

[hasty merlin]

so keep this in fpcharacterBP adn just add to viewport?

[gentle urchin]

Nooo

this should be a single widget

where you simply change the text shown

and/or icon or whatever

[hasty merlin]

a single widget? how do i make sure the size of the widget always remains centered?

[gentle urchin]

centered to what

[hasty merlin]

to screen

[cedar spoke]

set pivot point (anchor) to center and 0,0 as location

[hasty merlin]

each text is goign to be a different number of characters so size willl change

Light Up vs Extinguish. extinguish will take up more space

and then there can be overlap with the E key icon

[gentle urchin]

Allign center center

Text center

Hbox center

[hasty merlin]

its all aligned to center of screen

[cedar spoke]

So you should be fine

Try changing the text, it should be centered with this setup

no matter the length

[undone bluff]

set your anchor in the details

[cedar spoke]

Put both icon and text in parent horizontal container

So the layout is dynamic

[hasty merlin]

its an image so it wont let me put in children

shoudl i be using something else instead of an image?

[undone bluff]

put them in a horizontal box

[cedar spoke]

I mean:

• Horizontal
  • icon
  • text

[undone bluff]

a box can have multiple children

[cedar spoke]

I mean:

- Horizontal
    + icon
    + text

Icon and text are the children

[hasty merlin]

still use the black bar as an image?

[cedar spoke]

Are you talking about the background?

[hasty merlin]

yea

im adding to horizontal box

[cedar spoke]

use "Border" and set the color or image as the brush

Instead of image

[hasty merlin]

to the horizontal box?

[cedar spoke]

In my case I have border with box inside

But maybe it will work the other way too 😄

[cedar spoke]

No wait, yeah Border -> Box as child

[hasty merlin]

im selected on horizontal box

[cedar spoke]

Can you show hierarchy?

[hasty merlin]

havent added the rest yet

[cedar spoke]

You need something like this

[gentle urchin]

And size to content.

You dont't want to staticly size dynamic content

[hasty merlin]

what kind of box? still horizontal?

[cedar spoke]

Yes, if you want horizontal content

Meaning, stuff is laid in a single row

[hasty merlin]

size to conbtent is checked

[cedar spoke]

Looks good, now remove the old background and use Border as a parent of your horizontal box

Same with light gray border of button but remember about hierarchy

[hasty merlin]

i ahve border now. which on on top?

in heirarchy

[cedar spoke]

Like in my example screenshot before

[hasty merlin]

missed that before

and to change the colour?

nvm

[cedar spoke]

As a rule of thumb to add some bg just wrap the thing in border 😛

If it doesnt support background iself

[hasty merlin]

imma use that from now on

how can i round the corners?

nvm

i was clicked on wrong thing again

[gentle urchin]

Wasnt there a new thing for that

[hasty merlin]

okay now to get the E icon and progress abr to overlap

[gentle urchin]

You want em to overlap?

Overlay in that case

[hasty merlin]

i just realized i could probs put the Key as the bg imaghe for the progress bar

now its just stretched and not full size

[stable fossil]

Does anyone know how to read control rig blueprint variables from a normal blueprint?

[hasty merlin]

okay so in my new interface i have oninteract with input interactingplayers-characterobjectref

and getinteraction text

[burnt obsidian]

how can I check if more then 1 bool (out of 4) are active and if so do something but if only 1 of 4 bools is true do something else?

I basically want it that only 1 out of these can be active at a time

[gentle urchin]

XOR

[hasty merlin]

i was going to say or bool

whats a xor bool?

[gentle urchin]

exclusive or

regular or is inclusive

[burnt obsidian]

hmm but how would I do this with 4?

[hasty merlin]

what does that do differently?

[gentle urchin]

3 of em

[gentle urchin]

it only returns true if exactly one bool is true

[hasty merlin]

you can make a XOR bool and add pins to have all 4 connect at once

[burnt obsidian]

so like this?

[gentle urchin]

OR
0 | 0 = 0
0 | 1 = 1
1 | 0 = 1
1 | 1 = 1

XOR 
0 | 0 = 0
0 | 1 = 1
1 | 0 = 1
1 | 1 = 0

[gentle urchin]

yepp

[hasty merlin]

you cant add pins?

interesting

[gentle urchin]

not to that one

its lame

[hasty merlin]

that is lame af

[burnt obsidian]

nice it works! Thanks @gentle urchin

[hasty merlin]

how woudl you write xor in C++

!| ?

|| is OR

[burnt obsidian]

I guess you could doubleclick XOR

and it would open visual studio if im not mistaken

[hasty merlin]

i dont wanna do that

[burnt obsidian]

me neither

[hasty merlin]

oh well

[craggy flicker]

is it possible to create widget blueprints inside widget blueprints? For example, in my inventory, I would like to create a "slot" widget I can just drag and drop into my inventory. This slot widget would have functionality, such as mouse hover over and such

[gentle urchin]

bool UKismetMathLibrary::BooleanXOR(bool A, bool B)
{
    return A ^ B;
}

[hasty merlin]

squize whats next? oninteract in object bp?

[gentle urchin]

yes, that's the way to go

[cedar spoke]

I guess it makes sense, to have multiple pins you need to have a loop and it will cost you performance

That's why xor is simple in BP

[gentle urchin]

On trace hit -> Does Implement Interace -> Get Interaction Text

[gentle urchin]

This trace would happen basically all the time right, whenever the player is looking at anything?

[hasty merlin]

yeah

[gentle urchin]

So basically on Tick

[hasty merlin]

every 0.1 seconds it runs again

[gentle urchin]

sure

so if implement interface, then GetInteractionText from the hit Actor

using the interace message

[gentle urchin]

you wanna use the reuslt of the does implement interface in a branch

after the hit branch

So you can store a reference to the target, or clear it

[hasty merlin]

got it

on true?

[cedar spoke]

You could also do cast as it has two exec pins, one for cast success and other for failure

[gentle urchin]

cast to interface , yeah that's true

i keep forgetting about that one

[hasty merlin]

cast to interface? isnt that kind of a nono cause its not resourceful?

[cedar spoke]

You will need cast anyway to call the methods in the future

[gentle urchin]

Just go with the flow

😄

Casts are fine in many yscenarios

just not all

[hasty merlin]

cool

[gentle urchin]

Drag and Drop operation does that already

[gentle urchin]

I'd also make an event Dispatcher

"OnHoveredInteractable"

in the char bp

right. Then tick is the way

true

[hasty merlin]

oh like a new function?

[gentle urchin]

gotta change the tick timing

pre physics or something...

[gentle urchin]

like an event dispatcher

below functions/variables... at the bottom there 🙂

you can try overriding Drop

[hasty merlin]

were talkign in the BPI_Interactable right?

[gentle urchin]

No, we're now in the Character BP

were we're hopefully doing our last implementation 😛

[craggy flicker]

hm when attempting this, I keep getting
"Internal Compiler Error: Tried to create a property Slot in scope SKEL_Inventory_C, but another object (ObjectProperty /Script/UMG.Widget:Slot) already exists there."

When compiling multiple of my "Slot" widgets

[hasty merlin]

got that. call it?

[gentle urchin]

"OnHoveredInteractable"

[hasty merlin]

yup

[gentle urchin]

Oh right

[hasty merlin]

i drag it in and call?

or event

or

[gentle urchin]

I prefer functions so i'd say wrap it in a function

the "cast to interface" and store that reference

and calling that broadcast

stuff it in a function

that returns a bool

[craggy flicker]

oh nvm just a naming error for some reason

[rugged sierra]

I tried but it looks locked too. Do u know if it is possible to build custom drag and drop in bp or is that only possible in c++? 🤔

[hasty merlin]

when i drag it in i get the options
call
bind
unbind
unbind all
event
assign

[gentle urchin]

ignore that for now,

create the function first

select the "Cast to InteractionInterface"

right click -> collapse to function

[gentle urchin]

you can do it in BP but im not sure you can fix how the buttons are bound... seem to be done in #slate for minimal flexibility 😛

[hasty merlin]

what do i name it? the collapsed cast into function

[gentle urchin]

"UpdateInteractable"

[hasty merlin]

got it

[gentle urchin]

Cast succeed -> Promote the interactable pin to a variable

(not local )

[gentle urchin]

open the UpdateInteractable function

[hasty merlin]

opened

[gentle urchin]

I think you missed the input pin

[hasty merlin]

promoted

just typed before going back. my brain is mush rn

[tawdry raft]

I'm trying to use this but the camera keeps moving off to some other location

[hasty merlin]

i need an object input

[gentle urchin]

make it 🙂 Actor reference

[hasty merlin]

actor reference?

[hasty merlin]

got them

ty for showing the input/output

[gentle urchin]

Not sure you actually need the output here, kinda depends on how you do the rest

[hasty merlin]

i got that setup

do i need the doesimplementinterface?

[gentle urchin]

nah

[hasty merlin]

or i guess the update would already right?

[gentle urchin]

correct

if the cast fails, it doesnt implement it

[hasty merlin]

so now it can tell whether its a door, chest torch etc

[gentle urchin]

in the different objects that can be interacted with yes

[hasty merlin]

now for the update text then?

[gentle urchin]

you implement the "GetInteractionText",

[versed sun]

If it doesn't have the interface , it return the Default Values and continues the Exec , i believe

[hasty merlin]

man i wish my school that im paying WAY too much for woudl actually teach us UE. our core engine is UE and all they showed us was to import shit and blueprints exist. then told us to ahve fun

[gentle urchin]

changed the function a fraction, as we dont need the bool return

so it's just this

We need to create the widget next, and store it somewhere sensible

it could be in the character, but that's often bloated already, so I'd suggest either PlayerController or the HUD class

[queen dagger]

does event hit node automatically detect all forms of character overlap? or is that something I would have toadd beyond that

[gentle urchin]

"all forms" ?

[hasty merlin]

my delete key just stopped working

wtf

[queen dagger]

so like damage events, character overlap

[gentle urchin]

close and open the bp

[hasty merlin]

weird

why does it do that

i hoenst to god though my switch broke so i was going to replace it

im getting an error for return value

[gentle urchin]

refresh the node, remove the return value

[hasty merlin]

Pin Return Value named ReturnValue doesnt match any paramters

[gentle urchin]

refresh

[hasty merlin]

refreshw orked

ty

for the widget i just need to create and set it right?

like this?

[gentle urchin]

where is this?

[hasty merlin]

its in my fpcharacter

ill remove everything later

[gentle urchin]

Do you have a custom playercontroller ?

[hasty merlin]

no

i created enhanced inputs

and added to imc default

[gentle urchin]

Gotcha

well

lets stick with what you got then

Name the widget generically

"InteractionWBP" or smth

[hasty merlin]

W_Interact

[gentle urchin]

sure thing

[hasty merlin]

create it the way i showed?

[gentle urchin]

Add it to screen, and instantly set its visibility to collapsed

yeah

[hasty merlin]

its gettign created its just not being shown

[gentle urchin]

Add to viewport

is what shows it

[hasty merlin]

ill connect it up alter

[gentle urchin]

aaaddd to viewport

directly after

and set its visibility to Collapsed

[lofty rapids]

or set it and then add to viewport ?

or would that not work ?

[gentle urchin]

probably works ?

[hasty merlin]

yea i was just thinking add to viewport when i need

[gentle urchin]

i think you can also set it in the widget default values

[lofty rapids]

i'm just thinking maybe flickering

[gentle urchin]

so you wouldnt have to do it here

[hasty merlin]

and when not need romve from parent

[gentle urchin]

Nah just keep it in the viewport i'd say

[lofty rapids]

i put my widgets in the hud

[gentle urchin]

same but lets not use time on that xD

already using my entire evening on this lolol

[hasty merlin]

i dont wwanna fuck with HUD just yet

[hasty merlin]

im so sorry and thank you so much

[hasty merlin]

how do i set to collapsed?

[gentle urchin]

drag from the widget reference, set visibility

[hasty merlin]

collapsed not hidden?

[gentle urchin]

ye

[hasty merlin]

target? leave? or drag the widget

[gentle urchin]

widget

[hasty merlin]

done

[gentle urchin]

singleplayer ?

[hasty merlin]

yea

[gentle urchin]

perfect

open the widget blueprint

[hasty merlin]

graph?

[gentle urchin]

yepp

Event Construct is where we will bind to the delegate we created

[hasty merlin]

cool cool

[gentle urchin]

so

GetPlayerCharacter -> Cast to YourPlayerCharacter

Bind to OnHoveredInteractable

[hasty merlin]

create a new event?

[gentle urchin]

yeah

[pearl lagoon]

How would I fix the LMG firing as fast as you can click and force it to use the timer?

[hasty merlin]

the focused interactable what is taht connected to?

is that the get play character?

[gentle urchin]

You want to promote the casted character to a variable

that's what it would be connected to

we could ofcourse include it in the delegate directly, if we wanted to

but nah, not for now

[hasty merlin]

promote this to varaible?

[gentle urchin]

yes

[hasty merlin]

and set it righ then too?

[gentle urchin]

the input object to the cast is "GetPlayerCharacter"

[gentle urchin]

yes

[pearl lagoon]

Currently, this lets me hold down left click to shoot repeatedly, but I've found if you can click faster than the timer the gun will still shoot. How would I fix this?

[gentle urchin]

I see no timer

[cedar spoke]

When firing, assign current time to variable. When firing next time, check if enough time has passed.

[hasty merlin]

name it something like Playerref?

[tight pollen]

I need difference

[gentle urchin]

whatever , yes 😄

[pearl lagoon]

Its one of my variables

[honest bough]

for some reason my print string doesn't work, has anyone else had that problem before?

[tight pollen]

I have the game start time and the current time, how do I get how long a player is in the game?

[honest bough]

all i have is event beginplay, and print string

[hasty merlin]

im missing something ehre

[gentle urchin]

You're missing the return variable

open up the interface, and add it to the function definition

[faint pasture]

@pearl lagoonYou need 2 bits of state, whether or not the trigger is held, and whether or not the gun can fire from fire rate

[tight pollen]

I can't substract

[pearl lagoon]

Would I use Clear Timer by Function Name or Clear Timer by Handle

[gentle urchin]

well, what is "starttime"?

[honest bough]

Anyone able to tell me why this doesn’t work?

[gentle urchin]

there's a bug for that if im not mistaken

[hasty merlin]

OnInteract or GetInteractionText

[gentle urchin]

the string is empty

[honest bough]

its equal to the word "Boom"

[gentle urchin]

or the bp is not instantiated

[honest bough]

how do you instantiate it?

[gentle urchin]

Which one do you need to return a value?

[pearl lagoon]

So to do this would I put that in my GUN_PARENT or here in the player controls?

[gentle urchin]

drag it into the level

or sawn it

[faint pasture]

do this all from inside the gun

the only thing the gun should get from outside is the StartFiring and StopFiring events

[honest bough]

ohhh, thanks

[faint pasture]

whatever your base gun class is

[hasty merlin]

i tihnk get interaction text?

[honest bough]

do you always need to spawn blueprints?

[gentle urchin]

Correct

[hasty merlin]

so add an output

[pearl lagoon]

Ok, so which timer function should I use for this?

[gentle urchin]

blueprints , yes for them to execute

[pearl lagoon]

Cause theres a lot of them

[honest bough]

alright

[faint pasture]

Forget timers for now, get the logic right with a delay, you can later move to a timer

the point is you need a bool to represent whether the gun CAN fire

that bool is set false whenever you fire a bullet and set true after TimeBetweenShots

[gentle urchin]

I believe so yes

as we want to return something

[hasty merlin]

im missing how you got that node of target to focused interactable

[pearl lagoon]

So i need an extra variable on top of my FireRate float?

[gentle urchin]

Its from the player reference

[hasty merlin]

get foucsed interactable?

[gentle urchin]

or whatever you called it

[faint pasture]

Delay version:
StartFiring -> bTriggerPulled = true -> TryFireGun
StopFiring -> bTriggerPulled = false

TryFireGun -> if bCanFire && bHasAmmo && bTriggerPulled-> Spawn Bullet -> bCanFire = false -> delay(TimeBetweenShots) -> bCanFire = true -> if bAutomatic -> TryFireGun

[hasty merlin]

im not seeing the node

[gentle urchin]

check what you called it in the UpdateInteractable function 🙂

or in the variable section

Interactable something maybe ?

[hasty merlin]

new interactable

[gentle urchin]

right

so that's what you want in the widget

[hasty merlin]

i cant pull it out

[gentle urchin]

did you save it as the correct type?

[hasty merlin]

what shoudl it be? actor obj ref?

[gentle urchin]

No

[hasty merlin]

and i make it in BPI_interactable right?

[gentle urchin]

your character ref

[pearl lagoon]

maybe something like this?

[gentle urchin]

huh ? nono

[faint pasture]

not at all

[hasty merlin]

you had said in the interface

[gentle urchin]

In the UpdateInteractble function

is what i said

unless you're refering to something else

[hasty merlin]

i might have lost myself in tehre

cvharacter object ref?

[gentle urchin]

dont be afraid to post screenshots

its easier to know where you are...

[gentle urchin]

im just guessing that you understand me all the time 😛

[hasty merlin]

i thought i was tbh

[gentle urchin]

In here we dont need a return variable

close it, and leave it as is

[hasty merlin]

deleted ccmpiled and closed

[gentle urchin]

Inside the widget, we cast to our char

bind to delegate,

has new event

[gentle urchin]

grab char ref , check if there's a valid "AsInteractable"

[gentle urchin]

AsBPIInteraction*

my bad

[hasty merlin]

this then

[gentle urchin]

yepp

[hasty merlin]

ahhhhhhhhhhh

[gentle urchin]

ta-da

[hasty merlin]

thats where i was struggling

now the bpi interface does it need an output on gettext?

[gentle urchin]

Yes

[hasty merlin]

actor obj ref?

[gentle urchin]

Would that help us ?

What does the Name of the function suggest

[hasty merlin]

widget obj ref?

[gentle urchin]

x)

GetInteractionTEXT

[hasty merlin]

so just a text

[gentle urchin]

For now anyways

[hasty merlin]

i cant find a text obj ref if thats what im needing

[gentle urchin]

you just want the text...

[hasty merlin]

so this looks right

[gentle urchin]

yepp

Now IsValid -> Get Text -> Set Text (for the textblock you've added)

[hasty merlin]

rereferencing this

[faint pasture]

why does OnHoveredInteractable not give you the thing that got hovered?

[gentle urchin]

i mentionend it, but let it slip

my mistake

but now i wanna keep them focused on this next thing x)

would remove the need to store the ref, and drag the other ref from it, so would look a tad cleaner

[hasty merlin]

how i do that

[gentle urchin]

Go back to the Character blueprint

select the Event Dispatcher

[gentle urchin]

Add Input to it, of the type BPIInteractable

[hasty merlin]

character opbj ref?

[gentle urchin]

No

BPIInteractble

[faint pasture]

my man going from 0 to interfaces real quick

[gentle urchin]

change the type aswell

not Character

[hasty merlin]

actor right?

actor obj ref

[gentle urchin]

Noooo

xD

[hasty merlin]

text

[gentle urchin]

3 is the charm right

[gentle urchin]

Cmon...

that's not of the type BPIInteractble

currently the type is Text..

[gentle urchin]

🎉

[hasty merlin]

im slow today holy

[gentle urchin]

entire evening

i wasnt wrong lol

xD

then in the function

[hasty merlin]

do i need to set anything ehre?

[gentle urchin]

simply connect the variable

"AsBPIInteractable"

not from the Set nodes, but from a new fresh Get

[gentle urchin]

perfection

as if i made it myself

now back to the widget

[hasty merlin]

im back

[gentle urchin]

We no longer need to store the char reference

since we get the object directly from the event

you may need to update the custom e vent , (not sure if it does it automatically?)

[hasty merlin]

i connected the cast to bind event

[gentle urchin]

you still need to connect the pin from the Cast

good

Now, your TextBox for the interactable text

is that showing as a variable?

[hasty merlin]

no

[pearl lagoon]

I tried some things and got to this point. I still need assistance getting the timer to not shoot endlessly and also prevent you from clicking faster from it

[gentle urchin]

go to designer, select the text box,

up in the right corner mark "is Variable"

[hasty merlin]

tis a variable now

[gentle urchin]

So get a reference to it

drag from it and find "Set Text" (Not the tooltip one)

[gentle urchin]

Nothings unique in 5.3 vs before, the same concepts still work

Its just about setting up turn based, in general

[sage lagoon]

What about game mechanics?

[gentle urchin]

more or less the same, but now you can use GAS

[sage lagoon]

I did find a few links, but they seem out of date, since they focus on Unreal Engine 4.

[gentle urchin]

if you wanna dive into an existing framework

[sage lagoon]

GAS?

[gentle urchin]

Gameplay Ability System

[sage lagoon]

Huh. Never heard of that one.

[gentle urchin]

It's big, and hairy, so to speak

[gentle urchin]

connect it 🙂

you know where

All that remains

[sage lagoon]

You mean like this?
https://dev.epicgames.com/documentation/en-us/unreal-engine/gameplay-ability-system-for-unreal-engine?application_version=5.3

[gentle urchin]

yepp

[gentle urchin]

all you need to do now is implement the function in the interactable objects

[hasty merlin]

interface is implemented with the torch. ill try with one for now

[gentle urchin]

Is the function implemented?

this would be in the interactable object

[hasty merlin]

so in my case would that be in the construction script in bp_torch?

wait

hold on

[gentle urchin]

||No, it would be the interface function||

[hasty merlin]

yup

[sage lagoon]

What I'm thinking is...well, ever heard of games like Mega Man X Command Mission or Evolution Worlds or Wild ARMs? I'm thinking of 3D environments where random encounters occur without tagging any enemies and three or four party members take part in battles.

Example: https://www.youtube.com/watch?v=59HImqLlUBo&list=PLN9aWB4vculL46mdkK0lfSuSRLsCw0OWL&index=2 and skip to around 3:40.

Though the turn order part, I would like to approach differently.

[hasty merlin]

how do i edit in tehre?

[gentle urchin]

you must implement the function in all interactable objects

just like you implement the "interact" function

[gentle urchin]

like final fantasy

[hasty merlin]

not just the itnerface but also the functions themselves

[gentle urchin]

yes

you must implement the function

so it returns something else than nothing

[hasty merlin]

its not showing up

in here right?

[gentle urchin]

no

right under functions

[gentle urchin]

not sure if the template i got was free or not

i think it was

[hasty merlin]

right click add event?

[gentle urchin]

ye

[hasty merlin]

function or event?

[gentle urchin]

got a choise?

gotta be a function, as we want it to return something

[hasty merlin]

convert function to event isnt working. cant have output

so im assuming function

[gentle urchin]

yepp

[hasty merlin]

add to event begin play?

[gentle urchin]

No

just implement it

and return a meaningfull text

this is called from the interactable widget when necessary

[hasty merlin]

i am not following here

[gentle urchin]

you need to implement it

[sage lagoon]

Do you have a link to that?

[gentle urchin]

double click it

100$

heh

been a while, i guess 😄

[sage lagoon]

Yikes...

[gentle urchin]

100 may seem like expensive, but there's a few hours of work behind it 😛

[hasty merlin]

as for the state? i just grab my bool variabel of lit or or not?

[gentle urchin]

Sounds reasonable

[gentle urchin]

Perfect

test it

There's one bug i didnt consider, we'll see if you notice

[manic haven]

Hey all, hopefully this is an easy question. I'm trying to kill my pawn when it lands on the ground. It's not a character, so I can't use the "On Landed" event. The print string works, and I presume the variable is being set, but it's not spawning the emitter when it hits the ground. Can someone help me find out why?

I have a box collision on the pawn that is set to overlapAll

[sage lagoon]

Apparently. If only I knew how I could imitate that or put a twist or two on it!

[hasty merlin]

i want to confirm this looks right?

[gentle urchin]

test it

does it work ?

[faint pasture]

how is it moving?

[hasty merlin]

yes except the widget doesnt go away

[manic haven]

I am dragging it with a physics handle and throwing it in the air

[faint pasture]

ok turn on Simulation Generates Hit Events and use Event Hit

that's your trigger, defining "ground" is up to you

[gentle urchin]

guess it's time to debug then

[hasty merlin]

alreadya dded

[craggy flicker]

i think blueprints are aiding my OCD problem 🫠

[gentle urchin]

Dont do that

just call the same function, but without an input

[hasty merlin]

why not?

if nothing is hit visibility is 0

[gentle urchin]

the widget handles that

Just call "UpdateInteractable" ,

but with no input 🙂

[hasty merlin]

so liek this then

[gentle urchin]

perfect

[hasty merlin]

yayyyyyyyyy

now to fix the widget

[gentle urchin]

still one bug

[hasty merlin]

ill fight that later

[gentle urchin]

but i guess you didnt notice

[hasty merlin]

i need a break

[gentle urchin]

so it's probably fine 😄

[hasty merlin]

oh?

what is the bug?

[gentle urchin]

text doesnt update after you interact with it

unless you look away, and look on it again

[hasty merlin]

oh yeah my interaction just isnt working atm

how do i fix the interact no widget issue?

after interact wont the line trace timer loop get it again?

[gentle urchin]

Actually it will in your case

Since we dont look for difference in interactable

[manic haven]

Do I have to define the ground? What if I want it to die when it hits anything while traveling at that velocity? I changed it to Event Hit and it's still not spawning the particles or printing the string.

Or should I enable the simulation generating hit events on the mesh and not the box collision

[hasty merlin]

got it back to working perfectly

squize you are an amazing human being

ty so much for losing years of your life to help my dumbass

[gentle urchin]

😆 it was an experience

You got there in the end

Way cleaner than it was

[hasty merlin]

so much cleaner and i gotta go implement with everything now

[gentle urchin]

Make sure to take advantage of inheritance where you can

[sage lagoon]

If I had the money for that, I would have at least bought it for analysis to see how I could mimic that. Sure, I could experiment without tutorials, but I don't have any idea on how or where to start in making battle sequences.

[gentle urchin]

If you have many different torches, having A parent torch class is sensible

[gentle urchin]

Main reason i got it aswell

Its basically a fixed scene with some camera rigs

[hasty merlin]

the school im in advertises that we learn UE but they didnt teach us anythign past importing fbx and textures, making materials and blueprints are a thing. luckily i only have 1 type of torch. my chests though are a parent class and children bps

[gentle urchin]

Dynamic switching and moving on the camera rails

[gentle urchin]

Your school should pay me to teach

[hasty merlin]

apply at vcad

maybe the lawsuits agaisnt them for false advertisement will diminish

[manic haven]

Fixed it. The collision wasn't attached to the mesh, so it wasn't moving when I started dragging the pawn around. Thanks for pointing me in the right direction!

[orchid pollen]

Hey I have a tree view and I want to remove elements in it from a button in my elements widgets. I have tried to pass my root widget by a variable exposed on spawn (mega parent) but when i try to get it in my child widget it return NONE. What am I doing wrong ?

My child bp :

[rare juniper]

I'm trying to create a pause menu but when i try to press p in game nothing happens, could someone tell me what's wrong?

[craggy flicker]

I would create the hud on event play after you create your regular hud. Then, set the visibility of your pause menu to false via the visibility node. After that, change your input functionality to get the "NOT" of your current "isPaused"

So after you press p, check if the not of isPaused is true, then set it to visible and do your pause menu logic

[round spruce]

is there a way that i can make ++,+= etc etc operators in bp and make it as a template for any type to pass or have to make seperate ones for each type

[craggy flicker]

For ++ why not just do the add op + 1?

[frosty heron]

Shorter, neater, more readable

[craggy flicker]

Okay but wouldn't it be just one node anyways?

[frosty heron]

Still have more benefit

Also less error prone

[craggy flicker]

I guess you can make a custom C++ script to implement those operators by yourself

[frosty heron]

There is operator overloading in cpp

[craggy flicker]

but I dont see the benefit of doing that compared to just the add op

[round spruce]

yes this is a psossibilty but i wonder if there is <T> type in bp

[craggy flicker]

you could make a function that just takes an input and outputs the input + 1

[frosty heron]

U can do fancy stuff that needs custom implementation with operator overloading, but increment by it self is already a nice touch.

[round spruce]

so i cant to a temp type in bp this is your answer? XD

well c++ then ig

[craggy flicker]

wait what

[frosty heron]

Don't know

Never tried it in bp

[craggy flicker]

that seems completely different from your original ++ and += question lol

[round spruce]

how ?

[nocturne basalt]

halo! Was trying to make a lift. Thanks to Ryck0Shae made it. But the 1st attached code doesn't have door opening animation. As I had added it (screenshot 2) everything broke: the lift goes down as soon as it reaches the top and animations play at the same time.

Q: how to make timelines act one after another? At screenshot 2 they act at the same time

[round spruce]

" ++,+= etc etc operators in bp and make it as a template "

[craggy flicker]

oh for any type to pass, my bad just read that part

didnt read "any type"

[frosty heron]

There is wildcard, but I also never touched that

[round spruce]

yea i thought so XD

[round spruce]

never heard of it gonna check it up

[frosty heron]

How you gonna increment something when the type is not known?

[round spruce]

casting wont work ig? XD icant cast to flaot or int types ? ik casting is gonna be bad anyway mm

[frosty heron]

Casting is not bad, it is necessity. And in cpp land it's free since there is no hard ref produced

But then what would be the point?

U do have to cast to every possible object type that u want

Making template useless? Imo

U can cast to int and float , but what are u casting?

[round spruce]

for int and floats it will genertate the corresponding funcs inc++ for rot and vec idk i could make sth eles that use those 3 times and call it a day

[frosty heron]

@round spruce it's probably a trivial question in #cpp I don't know enough to comment.

Don't c template being useful tho , from my beginner pov

[round spruce]

i cant understand this wdym ?

[round spruce]

gonna ask there ty

[lean compass]

the default variables in my character blueprint reset everytime i open the editor does anyone know why this happens

[hasty merlin]

how can i change which percentage variable my widget progress bar is using depending on the object

[hasty merlin]

any chance youre still online?

i just got a question about change my interact inputs to be apart of the BPI_Interactable and get teh percentage value to change

[faint pasture]

what the hell would rot++ do?

[twin perch]

So is their no way to access the row number in a data table ?

ive got a skill list, i want to have the skill be ain integer, i want to them have my code say "if skill number Find row in Data table"

So first value in the data table = 1

each row in the data table has a number, but it seems like there is no way to access it .

[rare juniper]

Hey, for some reason my main menu in my packaged game doesn't work. when i press the play button nothing happens but in the un packaged version it works?

[dawn gazelle]

You'd be better off asking in #materials or #umg for something like this as you wouldn't be doing it programmatically in blueprints.
You'd probably want to use a material that has a parameter that allows you to set the particular texture you want to have outlined so you can create a dynamic material instance and feed in the texture to use, and then do something like what is recommended in this thread. https://forums.unrealengine.com/t/outline-mask-texture/138867/7

[dawn gazelle]

This isn't the best way to associate a number to a skill as you can reorder the rows in the data table which may break any code that associates that number with a particular skill.

That said, you can use "Get Data Table Row Names" which would give you the array of names of the data table. You can then use the "ID number" minus 1 to then look up the name of the row from that array. Then use the row name found to get the data table row.

Would look something like this:

[wheat zodiac]

Does anyone have any good resources for working with multiple voip outputs? ie. I'm trying to have normal voip and also channel the voip through a radio or intercom or such thing

Thanks

[lunar sleet]

Maybe #audio

[wheat zodiac]

good idea, sorry about that

[twin perch]

cheers that helped, i know its not the most efficant but i think its fine.

[frank viper]

Hi,
I am working in Unreal 4.25.
Running into a problem I see on Reddit and other forums is pretty common.
I am saving out a custom-built space station with over 400 parts, each colored, mesh chosen, light color chosen, etc.
So, its a single "save" command that checks and runs through a LOT OF NODES.
Getting the "infinite loop detected" error.
I know about the max number of loops setting in Project settings and made that 2000000000 but that didn't work.
I am working on breaking the saving BP up into several smaller BPies so when the one is done the process continues on the next Save BP, so Save 1 to Save 2 to Save 3 and so on.
Anyone had this problem and know if my current plan would work on not?
Thank you 🙂

There is no actual loop I am very sure.

Apparently this is a "false" detection by the engine.

If you have a single process running through too many nodes.

I tried delay nodes but that didn't work either.

[frank viper]

The other comment I saw is that I should collapse all the nodes into a Function.

[gentle urchin]

You could frameslice it?

[gentle urchin]

Interact inputs?

[hasty merlin]

i need to get this math to work somewhere

and i need to rebuild this mess differently as the code works diffeerently now

before i had multiple inputs to tell the difference between torch,door and chest

now i think i just need 1 but i ahve to rebuild that one to check what the line trace hit is'

just thinking about it i could also use elapsed seconds form the enhanced input to be my hold number

[gentle urchin]

Are there different interaction times?

[hasty merlin]

there are yea

door is 3 seconds torch is 1 and chest i think is 1.5?

[gentle urchin]

So thats another value we wanna get through our interface

[hasty merlin]

i added this into the widget

[gentle urchin]

GetInteractionTime

[hasty merlin]

i dont need either of these right?

on interact we amde before

[gentle urchin]

We need OnInteract

[hasty merlin]

do i need any outputs or inputs?

[gentle urchin]

We wanna avoid that i think

So that the stuff going on during the interact may be latent

[hasty merlin]

okay

[gentle urchin]

We want an output for the GetInreractionTime

[hasty merlin]

float value?

[gentle urchin]

Ye

[hasty merlin]

cool its named squizeTime

lol

[gentle urchin]

The Inputs are handled in your character right?

[hasty merlin]

yea

[gentle urchin]

So Event IA Interact.Started -> GetInteractiomTime

[hasty merlin]

before that, i made an entirely new input. should this be a hold?

and started not ongoing?

i want the key to be held to interact which is why i though ongoing might work

[gentle urchin]

Thats why we fetch the InteractionTime

[gentle urchin]

.Started -> Get Interaction Time -> start timer by event -> Custom event Complete interaction -> Interact

[hasty merlin]

delegated custom event?

[gentle urchin]

Regular custom event

[gentle urchin]

'Delegated' sure I guess

Connect it, yes

Red wire

[hasty merlin]

yup done

and then interact?

[gentle urchin]

Yepp

[hasty merlin]

the bpi?

[gentle urchin]

Yepp

You're on a roll

[gentle urchin]

Target is AsBPIInteract

Same for the GetinteractionTime

[hasty merlin]

i tihnk its cause im more overtired than before that im not making stupid mistakes cause im ticked now that ive spent 4 days, 14-16 hours a day trying to figure this out

[gentle urchin]

(You shouldnt have to convert it)

If you draw from AsBPIInteract and search for the same event you should get the correct one...

[hasty merlin]

should be yellow though right?

[gentle urchin]

Yepp

Also, grab 2 of the AsBPIInteract refs

Avoid those wires all over thenplace

[hasty merlin]

okay

[gentle urchin]

It quickly adds up

[trim matrix]

Are there any tips for unreal engine blueprints

[hasty merlin]

dont spend 60 hours in 4 days trying to solve one issue

a meme response but still holds true

[trim matrix]

I have a bad feeling i would end up like Sisyphus when ut comes to unreal engine blueprints

[hasty merlin]

am i goign to need an event dispatcher?

[gentle urchin]

Yes

You're on a rolllll

Also we wanna promote the timer to a variable

[hasty merlin]

im learning

you are truly an amazing teacher

event dispatcher looking like

[gentle urchin]

HoldInteracted would have a float value

[gentle urchin]

Or two

Current and Max holdtime

[hasty merlin]

sorry one sec

[trim matrix]

Does anyone know how to make a slingshot? Like in angry birds

[lunar sleet]

Maybe using the cable system and physics? 🤷‍♂️

[gentle urchin]

Isnt it just a projectile?

[lunar sleet]

I thought we’re talking about an actual slingshot

[gentle urchin]

Angry Birds 😅

I wonder if it would even work

[white oxide]

Noob question how do I create an object reference to my pawn child?

(Ball Pawn)

[lunar sleet]

You don’t. You get it from an interaction ideally

[lunar sleet]

I haven’t played that game in a long time tbh 😀

[lunar sleet]

Also what’s a “pawn child”

[white oxide]

My BallPawn inherits from a pawn

[lunar sleet]

So

Self

If you’re in the ball pawn bp

[white oxide]

No no

This is in another BP, it's intention is that it will restart the player when it collides with it

The original blueprint restarts itself but of course I do not want that behavior

[hasty merlin]

im back sorry, was in a meeting with my prof

[lunar sleet]

K well your cast was fine, what are you having issues with ?

[hasty merlin]

how do i add these again?

[gentle urchin]

Select the event dispatcher

[lunar sleet]

Ok so you don’t need the ball you need the restart object whatever that is

Is this just like an actor manager ?

[lunar sleet]

Are you going to have more than one of these restarts? Is it placed in your world? @white oxide

[white oxide]

It's the floor

I'm making a the Floor is lava game

And the floor restarts the player

[lunar sleet]

Ok so just one

There’s not multiple copies right?

[white oxide]

Just the floor, yes

[lunar sleet]

Get actor of class

Select the restart object from the drop-down

Don’t abuse this function, it’s not ideal for most things

[hasty merlin]

am i goign to need to cast again like i did with gettext?

[lunar sleet]

almost defeats the purpose of using interfaces 😀

[hasty merlin]

an interfaces are very fun lol

[lunar sleet]

They have their uses, but when you’re just starting out, a cast is easier to use

Makes your code more readable

[white oxide]

Still getting an error

[lunar sleet]

I said select restart object

Not ball pawn

[white oxide]

But why would I get the BP Restart when I'm trying to cast to my player object (ball pawn)?

[odd kiln]

Hi all ! Anyone can help me just a little bit with object type collision problems ?

[lunar sleet]

You’re trying to get the wrong thing. If on player died is on the bp restart you don’t need the ball

[odd kiln]

Both collisions have in "Object Type" = "Player" (a custom object response that I have created) and both are set to "Block" but they don't block each other..

[lunar sleet]

Show. And ideally they should be different object types and use a custom channel instead

[odd kiln]

So I set one object type to "WorldDynamic" and the other to "Player" and set both to "Block" but still

I'll show you

[lunar sleet]

Your cast is fine, but as far as I can tell your event dispatcher is not on the ball

[gentle urchin]

No need to cast,

You forgot to store the TimerHandle

[lunar sleet]

How are you checking for hits ?

[gentle urchin]

Its the output from the SetTimerbyEvent

[odd kiln]

My first Actor is my character and the second is another Pawn

I made these collisions "visible" to see if they block each other or not

[lunar sleet]

I mean what are you using

Event hit or what

[hasty merlin]

im not sure how to connect that

[odd kiln]

No I want them to be blocked physically like a cube a solid thing

[lunar sleet]

Oh lol that’s not the same thing

You need to have them Simulate Physics

[odd kiln]

So I need to set in collision enabled "Physics and query" ?

[hasty merlin]

do you mean like this?

[lunar sleet]

Yes and no. Literally search for Simulate Physics in the details @odd kiln

[gentle urchin]

Right click the output -> promote to variable

[lunar sleet]

Might have to go on the mesh component

[odd kiln]

But I don't understand, my default Capsule Collision of my player has not "Simulate Physics" checked and it collides with walls and Landscape etc...

[hasty merlin]

ok got it set

[lunar sleet]

Iirc that’s because the CMC has a bunch of things it does for you

[gentle urchin]

Perfect

[odd kiln]

CMC ?

[lunar sleet]

Character movement component. It uses the capsule heavily

[odd kiln]

Oh ok but it uses only the Root Capsule Component I guess

[lunar sleet]

Don’t get me wrong, block does what it says, but if you want stuff to like bounce off then you’ll need physics

[odd kiln]

I don't want bounce or something I just want a Collision around my player that blocks with another Actor collision

[lunar sleet]

if you want to test if they’re blocking each other use Event Hit and make sure generate hit events is ticked. That will tell you if it’s happening

[hasty merlin]

how do i set the value for current time? im assuming the max time i get to set in the object bps

[odd kiln]

So if the Event Hit is working it means it should blocks each other physically ?

[lunar sleet]

Yep

[gentle urchin]

Its set internally when you start it

So you can get elapsed time and the total time

[hasty merlin]

so no need to create an input on the function and connect it to the current time output?

[odd kiln]

Event Hit not working

Of course I checked the "Simulation Generates Hit Events"

I guess you're right I have to check "Simulate Physics"

[lunar sleet]

Event hit should work regardless

[odd kiln]

It does not

[lunar sleet]

Make sure your meshes have collision on them, or add extra box or capsule collision

[hasty merlin]

what is the next step here? is it to get elapsed seconds? if so how do i input that?

[odd kiln]

My meshes have collision on them and I added an extra Capsule Collision on both actors (as child)

[lunar sleet]

🤔

Collision is a tricky beast, maybe use alt+C at runtime to see the actual collision

Maybe they’re not close enough or who knows lol

[gentle urchin]

OnGoing -> Call the new dispatcher

[odd kiln]

That's why I made them visible lol I really don't understand

[gentle urchin]

Feed it SquizeTime and from the timer -> get Elapsed time

[gentle urchin]

Squize time is max hold time

[hasty merlin]

i also connected the bpi interactable

[gentle urchin]

Elapsed is current

[hasty merlin]

awesome and i can change squize tiem depending on what the actor is?

[gentle urchin]

Thats what we're doing yes

[hasty merlin]

awesome awesome

[gentle urchin]

Canceled you wanna clear and invalidate the TimerHandle

[hasty merlin]

cancelled and completed?

or just cancelled?

[gentle urchin]

Both is fine

[hasty merlin]

how do i clear and invalidate? ima ssunming is valid node

[gentle urchin]

Dont assume

TimerHandle is the context variable

[lunar sleet]

Drag from the handle, start typing clear
