[fluid wraith]

Apply damage is an interface message, it doesnt really care

[slender quest]

So I made a print string on Triggered and then one on Completed, and you can see that it did a bunch of them in pairs > Triggered, then completed, etc, until the last one where it triggered but then did not print the Completed string

[lunar sleet]

That’s very weird.

[slender quest]

yeah! what the heck??

in the tooltip for Completed output pin it says this :

[lunar sleet]

Well

[slender quest]

could it be that it's not firing due to this situation of "trigger reporting Ongoing" on the same frame?

[lunar sleet]

Is it firing the cancelled though

[slender quest]

the cancelled is routed through the same nodes, so it should have fired the Completed print string too if it had happened

[lunar sleet]

Maybe, you can check if it fires ongoing then

[slender quest]

Alright, I'll set up a print string for that and see what happens

[meager spade]

I'm not the sharpest rn but depending on what they mean wouldn't a node that does nothing hooked up to the ongoing solve the completed firing all the time?

[lunar sleet]

Is this on RMB or what key aims

[slender quest]

I'm using left trigger on my controller right now for testing

[lunar sleet]

Maybe, TBD what actually happens tho

[narrow surge]

I Added a reload animation to my character animations recently and the aim offset seems to effect where the left hand lines up to slam the magazine, so if i look straight, no issue, if i look down, the hand is off. How fix/ what words can i lookup to research?

[lunar sleet]

I wonder if it’s actuating twice very fast

[slender quest]

ah hmm hardware trouble?

or maybe im double tapping it fast

[lunar sleet]

🤷‍♂️ perhaps, tho I’d expect it to complete and retrigger but idk

Can always test on a different button

[lunar sleet]

Your actuation threshold is half a second

Ongoing usually fires when the threshold has not yet been hit but still actuating

I’d lower that threshold as well

[thick flame]

ok so. If I wanted my enemy and player to die when health hit zero, what would be the best way to do so? I have a death animation that works great, but I want to prevent movement, attacking, etc. Should I do branches and a "IsLiving" variable? or is there a prebuilt state for this?

[slender quest]

seems like Ongoing is never firing from my current test

I think there might be some kind of interaction happening as well between other actions i'm doing, because If i just wander around and aim and release i can't replicate this, but if i start dashing and attacking while also aiming and shooting sometimes, i can more reliably replicate it

[lunar sleet]

Generally if you enable physics that stops it from doing stuff I think, you can also destroy it and replace it with a dead actor, etc

[slender quest]

i kind of want to take a video of the gameplay to see if i can find a pattern in what im doing that makes this happen, it happens way too quick for me to see

[thick flame]

ohhhh

[lunar sleet]

Could be, maybe it’s hanging somewhere

[slender quest]

ill try testing on another button first and playing with the actuation threshold

[thick flame]

the enemy just attacks and comes back to life, its health going into the negatives so it cant be killed again

[lunar sleet]

Ok, maybe just replace it with a dead version

[slender quest]

So with the "down" trigger, the actuation threshold appears to represent the amount that the button is pressed down, if i put it to 1.0, i have to pull the trigger all the way down, and with 0, it activates as soon as i pull it a little bit

[thick flame]

ok

[lunar sleet]

Oh interesting

[thick flame]

time to figure out how that works JKLFSD

[lunar sleet]

😀

[slender quest]

thinking about it this way, do i really need Down, maybe i can just switch it to Pressed and get the same result i'm looking for, gonna try that

scratch that, I do need Down

[slender quest]

tried out left bumper button and it does happen again. I'm gonna have to take a video and slow it down to see what actions im taking that makes this occur and then go from there

[lunar sleet]

Usually yeah

[sleek elbow]

Can anyone tell me how to fix this

[warped lodge]

Hello, I have some questions about tile movement in ue5 involving a frictionless ice mechanic. I wasn't sure which channel I should ask for help in, and didn't want to be rude with an "all" call, but if anyone could help me with the functionality I would be forever grateful!

[devout oak]

How would i code this as a bp https://i.imgur.com/nFCk308.png

[kind estuary]

Im spanning factions on a map. How do i make sure they are far away from each other uniformly? So like how age of empires 2 does it. When the game starts all players are more or less apart from each other.

i tried generating a grid. and assign players to its own space, but sometimes players get too close

[versed sun]

Make a random Location A
In a random Direction, extend out X Distance to find Location B

How many players?

[cunning vapor]

Got it working with this; thanks for the push in the right direction; a small follow on question; how do i set the actorbeginoverlap to work with different/multiple boxes

[lunar sleet]

Wdym

Boxes on the same actor?

It’ll stack

[cunning vapor]

Is there a way around this ?

[lunar sleet]

Just gotta make sure you have the right collision settings

[lunar sleet]

Around what, do you want collision or no collision

[cunning vapor]

was thinking of "if this close - play this anim" , "if closer -- play this anim"

[lunar sleet]

You want to check how close you are to another actor?

[cunning vapor]

yes

[lunar sleet]

Use GetDistanceTo

[cunning vapor]

tyvm!

[devout oak]

anyone know how i would throw this into a bp

https://i.imgur.com/HOA4HvQ.png this is what I currently have

just not sure how to implement the pseudocode into it

[foggy otter]

where can i change the parameters of the default physics volume of the world?

[slender quest]

I finally figured out the main issue, which is when i dash and aim at the same time, it seems to cut the aim action out instead of completing or cancelling it

[lunar sleet]

Nice

[slender quest]

to be even more specitic, if i aim, and then dash, and then let go of aim while in the middle of the dash, it does not cancel

BECAUSE, during my dash, i disable input...

😅

[lunar sleet]

You disable input during input?

You can Add and remove mapping contexts if you want to stop it from reacting to movement while dashing

[celest tangle]

How can I return something from calling a custom event set to replicate on owning client?
I start in a function that is run on the server --> need to access the UI (client event) --> UI data sent back to the same (calling) server function.

[foggy otter]

afaik you generally cant. split the functionality into separate events.

[celest tangle]

kk ty

[gritty tartan]

I'm using a random stream and setting it in the game instance. When I pull the variable from game instance in a widget, the random stream always returns 0 instead of the actual random stream variable (I'm setting text to update what the random stream numbers are, so I can verify what it's supposed to be). Not sure why it's doing that.

[light summit]

is it possible to make a console command that puts the player in a free cam and despawns the possessed pawn?

[slender quest]

oooh, i didn't know about this, i should learn some more about that

I was just using the disable input node because it seemed to get me the effect I wanted at the time, but i see how it's limited

The mapping context sounds like an important concept for me to learn

[lunar sleet]

Yes it’ll go a long way

[slender quest]

So I can just swap the mapping context using something like this whenever the Dash is active, so that there's no movement input included, ill try to exclude the aim too

or i guess i could just remove mapping context and then add it back after the dash completes

[lunar sleet]

Yeah have everything you want not to be able to use in one context and the dash with other stuff you want to still be able to use in the other. Then remove the corresponding mapping context while dashing and add it back at the end of it

You can also break the options pin to force it immediately and so on

But if that’s not smooth enough, you can always use a bool check isDashing? on the movement and look IAs, not elegant but it’ll work

[wicked marten]

hey guys.. just wanna ask how to screenshot in game including UI...

[lunar sleet]

https://forums.unrealengine.com/t/how-to-take-a-screenshot-including-ui-only-using-blueprint/538031/2

done that but screenshot shows blank

ill send u pic of my BP and output

Did you use the last response in that thread ?

[wicked marten]

wait

THIS ONE?

[lunar sleet]

Yes

[wicked marten]

ill do it now

[wicked marten]

Gee thanks

[lunar sleet]

I’m not sure if that’s sarcasm but 🤷‍♂️

[wicked marten]

nah realy i was going crazy for 3 days

finding this

my only problem is the filename

i transfered from unity

impracticing here

[slender quest]

It fixes the aim issue, but now i'm getting something weird happening with the dash-attack and the shooting, which seems to be firing twice for some reason, but I will investigate this further. Thanks for the input mapping context concept, a good thing to learn

[wicked marten]

naah, i appreciate the help

[lunar sleet]

Break that options struct

There’s a couple of options in there

Play with those on both the add and remove

[devout oak]

Hey neo would you be able to help me with this?

[devout oak]

im just not sure how to implement the pseudocode into the bp

or where to

[lunar sleet]

Do you know what pseudocode means?

[devout oak]

is it not just a simplified language?

for programming

[ionic cypress]

It is not a language. Just for you to write down your logic

[lunar sleet]

Not really a language,
More like a description of the logic 🥈

Is this a class assignment or something?

[wicked marten]

simplified logic

of the program

[devout oak]

yeah but ive never translated something like that into a bp

[lunar sleet]

Logic in layman’s terms as they say

[devout oak]

so im just unsure of where to even start

[lunar sleet]

Have you done any normal coding?

[devout oak]

nope

[wicked marten]

YOUR DRAFT

[lunar sleet]

Ok, it usually helps to understand programming basics, were you told to just do all of this stuff in Unreal blueprints with nothing to go on?

[devout oak]

the only thing i have to go off of is the photo that i had sent

we were told to attempt to figure it out

but thats it

[ionic cypress]

Probably you'd better to check some blueprint tutorial first. There're a bunch of videos online.

It is not that a magic but need to spend time in it.

[wicked marten]

go tutorial

@lunar sleet is possible to open OS File browser in game?

[frosty heron]

Yes

[lunar sleet]

Whether you should is another story

[frosty heron]

I used it to find paths to movie and image file

[wicked marten]

only image

open OS file browser > select image> Display Image on screen > screenshot it again. simple as that

i have a project game, a 2d game like tradewinds

im practicing the basics

[frosty heron]

I don't know a way to serialise it tho, so basically you are just getting the path to the image file. You will need to load the image everytime you start the game again.

So what I mean is , if your user delete the image then it goes bye2

[thick flame]

oh man.... so, i got everything working between my player and one enemy, but when i place more of my BC it doesnt work. They will swing at the player if they are close enough, but they wont path to them and cant be killed by the player

[frosty heron]

Opening file browser requires cpp, I wouldn't have a clue my self and use a plugin

[lunar sleet]

You’re placing more actors of that class into the world or spawning

[thick flame]

placing

should I use a spawn system isntead?

[lunar sleet]

No, just wondering

You said those instances wont path to your player, did you check they’re on the navmesh and not in or above it?

[thick flame]

they dont seem to be clipping the mesh

[lunar sleet]

If your attack happens onSuccess and your move fails, they will be invincible

[wicked marten]

the purpose of the screenshot is, it will be the save file. the image

[lunar sleet]

Put a print string on the move failed

[frosty heron]

Ye you can do w.e you want with it. The image will be saved in your .sav folder tho which is editable and accessible by user (delete or edit in photoshop)

[wicked marten]

thats the point ahhahahah

but that will be later on

i dont know if thats absurd

[frosty heron]

Well it's not a good thing for user to be able to delete stuff from inside the game

[thick flame]

would that be reutrn value here? or do i need to code something to check for a miss

[frosty heron]

Anyway the plugin is called file browser if you want the OS file browser

[lunar sleet]

No, that’s a trace, talking about the AIMoveTo

[wicked marten]

ue5 .3?

[thick flame]

ohhh

[frosty heron]

No idea. I used it in my old project 4.25

[wicked marten]

cuz thereis none

[frosty heron]

Marketplace

[wicked marten]

custom bp right?

aaaaaaaaaaah

wait

[frosty heron]

It ain't free haha

Afaik

[wicked marten]

nah. thats not a problem

ahhahahah

i have budget

[frosty heron]

Not expensive tho

[thick flame]

its failing every tick lol

[frosty heron]

Just hope it support your ue version

[thick flame]

so its a nav mesh issue?

[wicked marten]

i hope so

[lunar sleet]

Maybe. Try rebuilding the nav, adjusting the positions of the actors on the landscape, see if that works

If not, you’ll need to use Visual Logger to debug

[wicked marten]

this one?

[frosty heron]

No

[wicked marten]

i think i saw a bp tutorial at YT

[frosty heron]

The one I used expose the actual OS browser

[wicked marten]

i need is not the actual OS browser

a simple browser like this

https://www.youtube.com/watch?v=AtoyZ8Wci00&list=WL&index=2&t=472s

[frosty heron]

@wicked marten https://www.unrealengine.com/marketplace/en-US/product/openfilebrowser/questions

[thick flame]

i cant find any doc on vislog

[frosty heron]

5.2 Max I think

[wicked marten]

shiet i have 5.3

planning to do 5.4 if released thats why im practicing

[frosty heron]

I haven't finished watching your tutorial but it seems he hard code the paths

Kinda lame to ask users to type in the path instead letting them pick the file from the browser

[wicked marten]

yapp...

pick is better than typing the whole shiet

[frosty heron]

What feature are u using in 5.3 anyway? I'm just glad I didn't upgrade atm given the bugs

[wicked marten]

i dont know yet.... im still practicing yknow

i thought the preview version is the buggy one

[frosty heron]

Yeah preview and 5.3

[wicked marten]

ahh i know

[frosty heron]

I'm using 5.1 dunnoe about 5.2

[wicked marten]

the auto ai generated environtment

[frosty heron]

But I didn't hear a lot of complain for 5.1 or 5.2

[wicked marten]

thats the feature im planning to use

im using archviz back 2020 - 2022

[frosty heron]

Hmm I think you can still use the plugin if you have the source build. I'm not sure, might want to ask around

[wicked marten]

i work at a school back then creating architecture mock ups of thier buildings

i did not need to do heavy blueprint pro gaming

programming

[wicked marten]

ill try doing tutorials first

then ask if my powers cant do this shit

about scroll list, i want show the contents of the first coluomn

[lunar sleet]

This is an #gameplay-ai issue now, but go to Tools -> Debug -> Visual Logger. Record and then run the game. From there you can click on each frame and see what the log says

[thick flame]

ok

[wicked marten]

do i need to put it manually or can i import in inside

[frosty heron]

You can use node in bp to extract the name into the box

[wicked marten]

this one?

do i need a loop for the list?

[frosty heron]

Yeah get data table row names

[wicked marten]

while loop?

[frosty heron]

Not while loop

[wicked marten]

just the 2nd coloumn

[frosty heron]

Get data table row names. For each loop (name)

Out struct , just grab the name

[wicked marten]

wer struct?

i dont know how for each works

[lunar sleet]

It just iterates over each element in the array

But that will only have one row

So one element

[wicked marten]

i mean how it works in bp

do i have to convert the row to coloumn?

[wicked marten]

is there any way to automatically put this in scroll list?

ill go to uncle google and understand how it works first

[lunar sleet]

Yeah I haven’t tried that before, but I’m sure it’s doable

[wicked marten]

and ill ask help if i cannot understand it. so i will not waste anyones time

ill be back

[dawn gazelle]

In order for something to happen smoothly over time, it has to be triggered every frame, not just on the click.

Instead, try using a variable for "Target". On click, set the target to what you desire. Move the Set Relative Transform Angle to run on Tick. Also make sure your interp speed is not too high otherwise it may happen too fast.

[dawn gazelle]

I think there's an "Ease" type interp to node.

[gentle urchin]

Doesnt regular interp ease?

I think it does

[frosty heron]

it's easing at the start too tho, not sure if that's what you want

Slow in Slow out is the term in animation

[ionic cypress]

regular one is linear I think?

[deep void]

How can i get a HUD user widget to communicate a bool with an actor component BP?

I've tried;

• exposing the HUD variable and doing a object reference to the HUD (never changes the bool in the component bp)

• exposing the component variable and doing a object reference to the component (never changes the bool in the component bp)

• Casting to the component (read none error)

• Casting to the HUD (HUD does not inherit from user widget error (it is a user widget))

I simply want the actor object (with actor component attached) to behave differently depending on which UI button is pressed.

[frosty heron]

Name is just a name, what you want to do when casting is to check for the object type

User Widget is not equal/inherit/share the same base class with HUD, your casting will always fail

[deep void]

I don't really understand this part of casting, so what would be the object type for this to work?

[frosty heron]

So you need to check what your Hud Ref is

hover over the blue pin and you will see the Variable type of HudRef

from what I see, there is probably no casting required here. You simply have not set HudRef

casting is just a type check

[deep void]

i have set it to an object reference of my hud

[frosty heron]

then you don't need to cast

you are trying to get TFHUDWidget anyway

if you get access none then you simply have not SET HudRef

you are trying to access an instance that doesn't exist in memory

[deep void]

fair enough, then why won't this work?
I am changing testbool in the HUD, yet it doesnt change in this bp

[frosty heron]

because you have not SET HUDRef

for the 4th time 😄

It needs to point at something that exist

You can create a variable of MyPlayer in a bp. It will point at nothing until you tell the engine to, Hey Point the variable to this MyPlayer that just step into my trigger (for example)

Refer to your error here

[deep void]

i thought we just established that i had set it, to an object reference. You then said that i don't need to cast.

If im not setting HUDref to an object reference of the HUD BP, then what would i set it too?

I get the logic of your sentence, but how do i "point" a reference in blueprints?

[frosty heron]

We never established that you had set it

hence the error

This is example

Using the variable as is without setting(pointing) will result in runtime erro , Green is SET. Now MyActor points at the Actor that I spawned

if I get MyActor->DestroyActor
It will destroy the character that I spawned

[deep void]

i understand getting and setting an actor, int, bool etc for the purpose you mentioned.
But that's not really what i want to do, or at least i don't see the connection.

I am setting a bool in my HUD, i want an actor component to be able to read that bool.
The bool in the actor component BP never changes
Even when it is changed in the HUD

[edgy ginkgo]

is there any way to allow a player to use the foliage brush in game in unreal?

if not would there be any way to simulate it?

[frosty heron]

You are making it really hard to help you. You can forget about setting or getting member variable when the variable it self is not set yet. Hence the error

You have not set your HudRef hence accessed none. I can't tell you more than what I've told you already

[deep void]

But how do i set a variable to a blueprint, in your example you're linkning spawn actor into the set. All im asking is what do i link into my set

[frosty heron]

With c++ anything is possible

[frosty heron]

I've given example, in your case you need to set the hudref to the hudref that exist within the world and that you want to use/access

If you have trouble with that, try to watch blueprint live communication video in this channel. That will help you understand

[deep void]

that's what I'm trying to do, i get you're saying i need to set hudref to my HUD or ill get the error.
But what im asking is how do i set it to my HUD? What goes into the set pin?

I thought setting hudref to an object reference of my hud was doing this, but i guess it isnt, so how do i set it, how do get my HUD onto the BP so i can plug it into set

[edgy ginkgo]

if only I knew enough c++ to help

[frosty heron]

You need to set the hudref to an instance of hudref that you want to access. I give up at this point if you still don't get it. Refer to blueprint live communication video to brush up on the basic

[gentle urchin]

This is just defining its type

So its a pointer to your hud type

But its a nullreference by default

It knows what type of object instance it can point to

But doesnt actually point to anything yet

Hud is accessible from playercontroller

If the owning actor is pawn you can set the hud rer like this:
Get owner -> cast to pawn -> get controller -> cast to playercontroller -> get hud -> cast to myhud

Then you set your hud reference to the output object of that cast

When that is done, you can access the hud directly from that varoable, assuming all casts succeed

[deep void]

I dont know how else to say this, again i get it has to be linked, I understand the logic, all I was asking is how, as in what node goes on the blueprint for this to work. I'm checking out the video, cheers for the link

[deep void]

Thank you so much for explaining it clearly and providing instructions, its greatly appreciated 🙂

casts mostly worked, only problem being is that all my logic is handled on a user widget on my HUD. There doesnt seem to be a get user widget node available from HUD

[gentle urchin]

Where are you creating this widget, and storing a reference to it ?

[deep void]

on my main hud bp, and it has a reference there.
(I'm pretty new to this and followed a tutorial for this hud set up)

[gentle urchin]

Right

So you wanna cast to main hud bp

[frosty heron]

UserWidget is not your HUD,
Go to your world setting , check the HUD that you use

cast it to that, then get MainHudWidgetRef

[gentle urchin]

And not the widget direvtly, as thats not a valid type conversion

[edgy ginkgo]

is there a blueprint to adjust cursor speed?

[frosty heron]

Don't think you can do anything with hardware stuff with BP. the most you can do is adding sensitivity for Aiming your weapon and the likes

but mouse speed in widget is OS dependent afaik

[deep void]

cast to pawn is failing

[gentle urchin]

Well

Who is the owner ?

A random actor?

Owner being whoever "holds" this component

[deep void]

its a component bp on an actor bp, so i assumed target self is fine

[gentle urchin]

Actor bp...

[frosty heron]

when in doubt, print it

[gentle urchin]

So owner is not player

Or player pawn

[frosty heron]

Get Player Controller -> Get Hud probably works

[gentle urchin]

This logic feels like its way off

Whats it supposed to do ?

[fading plank]

https://imgur.com/a/f9jGIsP

[deep void]

this worked, thank you

[fading plank]

For some reason the timeline just wont reverse when the button is released, it stays at the max value. What am I doing wrong?

[gentle urchin]

You cant set a replicated value from a client

Not the reason it doesnt work, but another issue

[tame pecan]

you can, just wont work as you expect

😄

[gentle urchin]

Yeah :p

It only works locally

[deep void]

its working without the cast to pawn, thanks heaps for your help.

Its for a building simulator style game, with placeable objects, objects that can be selected (logic in the actor component bp)

However i noticed when you're placing objects on the grid, you can sometimes accidently click and highlight / select objects.

So ive made a 'select' button on my hud user widget, I just havent been able to get it to change a bool in the component bp that says "yes you can click"

[fading plank]

Tsk. I'll need to figure that out some other time. Right now I'm more worried about the timeline not reversing

[dim flume]

Hello! I took some a project that was using the Angelscript version of UE (the one from Hazelight) and I wanted to convert all my Angelscript classes to C++. I did that with no issues but then the blueprints that had those classes as parents have lost the parent and are showing None as the parent. I thought I would just reparent them to their new C++ type but all of those classes are not shown in the filter when reparenting... and that's weird as they are all derived from either APawn of AActor. I though I would give a try with CoreRedirects and point the old classes to the new one there but nothing to do there either. Do you have any suggestions?

[frosty heron]

I Don't use enhanced input but im pretty sure cancelled is not what you want

try to click on the drop down arrow and see your options

[gentle urchin]

This sounds very backwards

Selection, currently selected etc should live in the pawn or playercontroller

Id go with pc

[frosty heron]

maybe completed?

[deep void]

ill see about moving it there, i was just adding to the existing logic from a yt tutorial, which is all in the component bp on each placeable actor

[gentle urchin]

Ugh... tuts

[fading plank]

That did it!

[gentle urchin]

Check out cropout

Didnt they also have building selection

[deep void]

will do, thank you so much 😁

okay now I am facing a bit of a complex issue. In my game players click and drag on the map to spawn trees this fully works in the level however when the level is loaded from the main level the cursor is still visible but is no longer able to click and make line traces

though the cursor is visible the cursor appears as a cross

[versed sun]

across from what ?

[spark steppe]

have you changed the input mode in the main menu?

you'll probably have to set the game input mode to game or game and UI

[edgy ginkgo]

I have not

[spark steppe]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Input/SetInputModeGameAndUI/
https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Input/SetInputModeGameOnly/

try those on beginplay in your level blueprint

or in your player blueprint if it is a character

[edgy ginkgo]

thanks for the help

it almost works!

so the click works now

but now regardless of the setting for that node the mouse cursor locks when clicking

ah I fixed it

thanks for you help

Is there a way to add an actor component via construction script and have it visible in the actor component hierarchy?

[gentle urchin]

doubt it

[restive rose]

[versed sun]

Looks like you have one of these in your ALS_Player Controller that doesn't have a Class pugged in right

[maiden wadi]

Not really. It doesn't really make sense to edit a component added from the construction script. The moment you edit it, the script will run again and rebuild the component. The point is to edit them from the script itself. If you want extra components that you can edit on an instance in a level but not make it part of the defaults, just add it to the instance.

Need some help, currently trying to increase a sizebar called Stamina Bar Reducer that will shorten the green bar before the end of the total bar but as you can see in the video there is an issue where it's not working. Is there anyone around that can help?

[random solar]

It's still doing the same issue

I am doing a cast to where it's made but I'm having it be hosted in another BP if that helps

[maiden wadi]

If you increase the sizebox's size in the designer, this works fine, right?

[random solar]

Yes, adding 15 to the width overide works fine

[maiden wadi]

Is your cast successful? Is that a valid reference?

[random solar]

Hmm, it comes out as failed actually

[maiden wadi]

Did you set the property that you're trying to cast from?

[random solar]

I'm pretty sure I did user widget object reference for the variable

If that's what you were asking about anyway

[maiden wadi]

What blueprint is this logic in?

[random solar]

It's in my top down character

[maiden wadi]

One consideration would be, why does your character care about this widget? The widget can get your character much easier.

[random solar]

This widget is the stamina bar. The stamina bar is affected by a few mechanics such as movement states (How fast it's moving) and how much stamina is consumed by the character

[maiden wadi]

The widget can get all of that state as well. But that's maybe a topic for another time. Usually you don't make a gameplay class care about your UI like this.

My original question was just if you set the pointer. I assume since it's failing, that it's a blank pointer of a type. You need to get the widget somehow and set it in that pointer.

[vernal pelican]

why is my cast not working

[random solar]

In the widget, I have this

[maiden wadi]

Because Actor is either not set to a specific actor, or that specific actor is not a DOOR.

[vernal pelican]

how do i set it to a specific actor

[lunar sleet]

Get a reference to that actor

Through an overlap event for example

[silent ledge]

Hey people, I am currently having an issue with Unreal, when working in my current project, sometimes when I close the game to continue editting blueprints, the engine freezes and crashes quickly after, the Crash Reporter keeps giving me the following:

Assertion failed: Index>=0 && Index<NumBits [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\BitArray.h] [Line: 1265]

I am unsure what is causing it. Does anyone know anything that could help me?

Thanks in advance!

[slender quest]

I played around with a bunch of the options but it didn't really fix the double input, though one configuration brought back the original issue. I'm not sure i totally understand what the options are doing. However, I did fix the problem by adding in the attack and shoot buttons to the new mapping context, so that they get "carried over" so it doesn't trigger them twice anymore. Thanks for all your help!

[snow rapids]

Hello you lovely people! I can not figure out how to move an actor to a point from pcg. Can you help?

[faint pasture]

However you want. How do you WANT this code to choose which actor it cares about?

[mental trellis]

You'd have to install the editor debug symbols to glean anything from taht - they're 80gb and probably won't help, though.

[fallow dune]

Hi! Does anyone know how I can set on which display my game is on? Thanks!

[silent ledge]

hmmm okay, thanks!

[mental trellis]

Does it happen every time you stop your game?

[silent ledge]

not everytime, about once every half hour so I would say 1/20 times, but there doesnt seem to be a pattern for whats causing it

[fallow dune]

im having the same issue

[lunar sleet]

What engine version

[fallow dune]

altough for me it seems to freeze permanently

[fallow dune]

ue 5.3

[silent ledge]

same here

[fallow dune]

yeah

[lunar sleet]

Try updating

[fallow dune]

it didn't happen before

[fallow dune]

I can't see the new engine version in the launcher

do i need to get it off github?

[silent ledge]

thing is I dont think its my version, Ive been using 5.3 for about 1.5 months now and it only started happening earlier this week

[lunar sleet]

No, you should see Update

For 5.3.1

[silent ledge]

but I will have a look anyways

[fallow dune]

I did a while back, but nothing changed

[lunar sleet]

Weird, no clue tbh

[fallow dune]

yeah, i've seen they fixed a couple of bugs that i've been running into with the new version

so i'd be worth updating

[gentle urchin]

Update launcher

[keen hedge]

Is there a way to get a viewport in a SceneComponent subclass?

[fallow dune]

where?

[gentle urchin]

Settings/options

[lunar sleet]

A viewport? What are you trying to do ?

[keen hedge]

Create a actor component (scene component) w/ its own actor component hierarchy, so w/ a mesh etc etc

[lunar sleet]

Components can’t have components, they can however be roots for other components. Not sure what this has to do with viewports

[keen hedge]

Yeah, that is unfortunate. The viewport I was asking for would be an attach-relationship, like how you attach scene components to other scene components in an Actor

Not sure why this isn't possible for scene components themselves

I mean I guess it is possible by manually creating and attaching other scene components - but why doesn't the Editor just give you a viewport to do that ugh

[lunar sleet]

If you meant the viewport tab that’s specifically there to see and fiddle with the mesh

[keen hedge]

Well yes which is exactly what I want to do in my SceneComponent subclass 🙂

[lunar sleet]

A component cannot contain a component. The attachment relationship is merely platonic, it’s only there to affect transforms and give you access options

[keen hedge]

Dunno why epic didnt just implement "components containing components" by components NOT containing components and instead having whatever actor the main component is added to be the owner of other components, while allowing you to actually use the editor to create these relationships/attachments. Of course I'm talking about scene components specifically here
Oh well

[lunar sleet]

You can attach actors to actors if you want to

Dynamically

[keen hedge]

Yes but my point is I cannot create a reusable scene component that will have other components attached to it other than doing so manually at runtime

[lunar sleet]

Just make a base class

And extend from that every time

Use inheritance

[keen hedge]

Yes that is exactly what I want to avoid

Instead of having composability as a choice, you're FORCED into inheritence like its 1999

[lunar sleet]

Lol

[keen hedge]

And OOP is the shiny new thing 😄

[lunar sleet]

Rule #1: don’t fight the engine

Inheritance is OOP

[keen hedge]

Yes, and it was shiny in 1999 (well more like in 1979 but still)

Ok rant over, sry for that

https://giphy.com/gifs/billions-season-3-showtime-B1pANeU1BTfhsERKQS

[maiden wadi]

Nothing wrong with inheritance. Also nothing wrong with composition. But if you want a decent project you really need both and to not choose one over the other. Like any other tool they have their uses.

[golden pewter]

if i were to make something to detect when im placing an item in my level to match the direction of a wall, would i use a widget or an actor in my level
some sort of panel that detects mouse hover and changes the rotation of the item accordingly

wall is just a background image

[faint pasture]

@keen hedge you're doing modular building right?

You want to have a thing which contains things which contain components

[keen hedge]

Yes, ideally that's what I'd want

I guess I'll settle with child actor components that (al least so far) seem to be working better than in 4.27

[faint pasture]

Yeah CAC will do the job but I don't use them, it's all just actors in my project. Can't visualize a thing made up of the actors at editor time but there's ways around that for me

For context I'm doing modular vehicles

[keen hedge]

Well I know that Tom Looman, in one of his talks, as a workaround decided to create his elaborate actor as an entire Map/Level

So he can visually see what he is doing when creating elaborate setups

He just parents everything under the main actor BP in the level hierarchy and then streams the "level" in when he needs to load and use the actor

[faint pasture]

Yeah that's an approach

My game centers around a vehicle editor so I just use that to make the pre-built vehicles

[keen hedge]

Just seems kinda overkill

[keen hedge]

Curious, what are your "ways around that" 🙂 ?

[faint pasture]

My game revolves around player built designs so I just use the vehicle editor I already have. The entire vehicle is baked down to a "recipe" struct which is used to spawn it.

Basically my editor is in the game.

[desert briar]

is it a bad idea to have a blueprint variable that is an array with 300 960x540px textures?

[faint pasture]

Nah go for it

it's not really an array of textures

it's an array of references to textures

[desert briar]

awesome, that saves my ass

[faint pasture]

I gotta ask, wtf are you actually doing tho

[desert briar]

😂 i think you're nice for not asking this the very first thing

[faint pasture]

flipbook animation?

[desert briar]

i'm adding tutorial videos, to be displayed in UMG. the built in mediaplayer stutters on looping. the electra plugin crashed on me after playing for 10 minutes (and i got no idea how to debug it, so f that). flipbook animations can't be used on images in UMG

=> i've written an own flipbook player in umg. dynamic material with a texture parameter - update texture index with delta time and swap out the texture

turns out my own flipbook thing uses 100mb less ram than the electra player

[maiden wadi]

Default Meda Player in Unreal is really bad. If you want a media player, enable the Bink plugin and use that. It's infinitely better. Less runtime resources, better compression for file sizes, and also runs on most all platforms.

[desert briar]

Thanks so much! I’ll try that next time

[maiden wadi]

Also not sure I'd use it for flipbook stuff though. Maybe. Depends on the context I guess.

[desert briar]

This flip book thing is only a workaround because the video players sucked. Would have been so much better to just throw my video in there

[maiden wadi]

Ah. If it's for a real video than 100% the bink player. The only real downside is that you have to open media via a relative path to the project root. And you have to run your media through their converter to "bink" it. But neither of which is really painful to work with for the benefits.

[worldly oar]

im trying to highlight a button in the widget blueprint (in ue5) and added an animation to it. The animation is the opacity goes to zero and an outlined box appears on clicked and then i want it to return to its original state. I used event on clicked for the highlight and on released to reverse the animation. The blueprints i used were the event to play animation with the ref to the animation in play animation. any ideas how i can return the button to its original state when clicked again?

[maiden wadi]

Sounds kinda like you'd just play the animation in reverse?

[worldly oar]

yes i changed that in the play animation node

but you mean create another animation in reverse

[maiden wadi]

No. You can play the same animation in reverse. You've already played it forward, so that's where the state is, so if you play it in reverse, it will go backwards to where it started.

[worldly oar]

yes thats how the nodes are

but when its clicked again

it doesnt reverse the animation

[lofty rapids]

you probably want a boolean or flip flop

[lofty rapids]

"on released to reverse the animation" <-- this didn't work ?

[worldly oar]

hmm ok

doesnt work

was thinking might be the released node that needs to be switched

[lofty rapids]

I'm not understanding, on released doesn't "reverse the animation" ?

[lofty rapids]

"On Pressed happens the moment you click on the widget. On Clicked, on the other hand, triggers when you release the mouse button."

https://forums.unrealengine.com/t/widget-scritping-difference-between-on-clicked-and-on-pressed/129493

[maiden wadi]

Yeah.

Swap Clicked for Pressed. You only used Clicked when you want a specific Down and Up press event.

[worldly oar]

thank you!

[night trench]

I saw in tutorials that this should work to add upward movement to a ThirdPersonCharacter, but it's doing nothing but control how intense the forward movement along the ground is, can anyone help?

[maiden wadi]

Is your Pawn a character?

[night trench]

Yes.

[maiden wadi]

It needs to be in Flying MovementMode for this to affect it like that.

[golden pewter]

what actor can i use to detect mouse hover in my level
and in relation to this topic i cant get nav modifier volume to detect my mouse
hover or click

[night trench]

Perfect! Thank you.

[onyx token]

is there a way to detect if an actor is no longer 100% overlapping a collision?
there's ActorEndOverlap - but that only triggers if it's completely outside
i need something that triggers when it's only just poking out

[night trench]

And, if I wanted to create a custom pawn controller to do this? (aka, one without a character movement controller)

[maiden wadi]

What do you mean by "Controller" in this sense? The Controller technically doesn't have much to do with movement. I assume you mean the CharacterMovementComponent?

[night trench]

Apologies, I meant 'character movement component'

[maiden wadi]

In that case it depends on your movement component. Normally the usual go to is the FloatingMovementComponent, which will basically act the same as the CharacterMovementComponent in flying mode. The ProjectileMovementComponent isn't really meant for being controlled so much outside of maybe affecting it's direction for like a guided rocket.

If you created your own custom MovementComponent, then that would be entirely up to you, based on how you choose to interpret the input direction and scale.

[night trench]

I think that has given me enough to google to move some steps forward. Thank you very much for answering the basic questions, it means a lot.

[maiden wadi]

Generally speaking, if anything is network related, it's usually best to hack up the CMC in some way.

Singleplayer? Doesn't really matter as long as it moves how you want it to.

[faint pasture]

Why videos?

Why not just sequencer

[trim matrix]

Any best practices that I need to know for doing global project constants? (Actually, I'm using .ini files)

[desert briar]

because it's 1000 times easier

[thin panther]

Using UDeveloperSettings is generally decent

[zealous moth]

@onyx token no you would need to use multiple detectors inside and out.
What's the use case?

[onyx token]

i figured it out, i decided to use multiple detectors

[zealous moth]

Hah nice

[onyx token]

I wanted to make a detector that won't let me build a building outside of my countries border in a lil strategy game

[faint pasture]

That's pretty hard to do

[onyx token]

well-

[faint pasture]

What are the shapes, arbitrary?

[onyx token]

i decided to always make them rectangles, add lil collision bodies to each corner and work with OnActorEndOverlap

fug it

[zealous moth]

Oh nice

You can do dx/dy

Might kill your cpu on tick

[faint pasture]

What shape is the outer collider?

always the same or arbitrary

[onyx token]

that ones basically arbitrary, made of a bunch of capsule colliders

(if you build an outpost, it increases your borders by a smaller radius than the town center, etc.)

[faint pasture]

You could just do a distance check

is it effectively 2d?

[onyx token]

ye

[sick fable]

can someone link me a video the basics of blueprints It was like an hour long someone linked it before but I forgot

[faint pasture]

yeah you can do distance checks

[onyx token]

but then i would have to distance check every corner of my building, with the nearest object, dependent on their radius.

And if an enemy builds an outpost next to your border, your border gets shifted by the difference between your outpost & their outpost

[frosty heron]

Blueprint live communication by epic

[onyx token]

and im already getting a headache

[sick fable]

thank

[onyx token]

i wanna use the colliders

unless it actually does kill fps

which it might

but i hope it wont

[steady night]

how would i use a BP struct efficiently

since if u make the slightest change in it it resets all vars related to it -.-'

[onyx token]

be happy it doesn't brick your project anymore.

Which it did.
In the past.

[steady night]

wdym ?

brick?

[sick fable]

actually anyone got a recent link

for unreal 5 in depth blueprint

tutorial

[onyx token]

if you changed something in a blueprint struct, and it was in use, sometimes (i had it happen once), your project got completely bricked.

as in

ded.

shit stopped working, you better be usin git levels of ded

so it turned into a nice, useful brick

[lofty rapids]

you know anything about programming ?

[sick fable]

well I know about about python

I have a decent grasp on blueprints

[lofty rapids]

ok so this is a real long one i have not been through it all myself

[sick fable]

but I have no idea about construction scipts and stuff

[lofty rapids]

https://www.youtube.com/watch?v=6UlU_FsicK8

but after the landscape part he gets into blueprints

[sick fable]

I will watch this whole video for 11 hours straight if its good

cuz I got nothing better to do

[lofty rapids]

i been picking at it stopped awhile ago have not gone back

i'm like 4 hours in

[sick fable]

ok

[lofty rapids]

but it helped a bunch

[sick fable]

thanks

can always rely on you

😆

[frosty heron]

You just dont

Use cpp struct. It's easy to declare

[spark steppe]

you save everything before you modify the struct, then you modify the struct and save it, then you quit unreal and when it asks you to save anything else you DONT save that

then restart the editor

[frosty heron]

Let's say he saved it by accident tho

If he used the struct in 40 bps. He has to recompile all those 40 bps

[spark steppe]

and they are most likely broken

[frosty heron]

I would use cpp struct any day over going thru that

[spark steppe]

if he can even open them

but that's what sourcecontrol is for...

commit before such changes which are likely to screw over your whole project

[cunning vapor]

If an actor is launched (Launch Character node) and hits another actor; is there a way of transfering some of that velocity/launch ?

[frosty heron]

In what way?

You can just apply the velocity to the other actor upon collision

[cunning vapor]

How would i specify that exact collision and not any others ?

[frosty heron]

Get the collision component that overlap with the other actor?

[steady night]

@spark steppe oh that will not reset ?

[spark steppe]

depends on your changes

but it's the most safe way to modify a struct

[cunning vapor]

thanks! just trial & erroing what nodes to use now 😛 will let you know once i get it

[frosty heron]

Select the specific collision volume you want to use. Then click on event begin overlap

[cunning vapor]

sorry; just tried but am a tad confused;
There is a horde of zombies; when one is kicked (player hitbox) they are launched but stop dead in their tracks when they hit another zombie; if i set it to overlap capsule (for the zombie) and do cast to zombie - launch; won't that launch everytime they walk into each other?

[lofty rapids]

most likely yes

maybe you can check for amount the zombie is moving if it's above a certain amount then do the hit

[barren kestrel]

Hi guys, I wanted to make a calender for my game that is accurate to the one in real life any idea how i would do that

i.e I know about the get now or today nodes i just want a way to convert those digits into the date like Tuesday 12 february 2029

so that no matter when the project is viewed the date will be correct

[spark steppe]

if you break the datetime struct it will give you all those data

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/DateTime/BreakDateTime/

and there's a format text node which does more iirc

[barren kestrel]

yeah i know that but the problem is it returns integers i wanna convert that into a string i.e 06/10/2023 to friday 6 october 2023

[barren kestrel]

even using that i cannot determine the sting equvalent of date and month

[spark steppe]

there's some stuff in cpp https://docs.unrealengine.com/4.27/en-US/API/Runtime/Core/Misc/FDateTime/GetDayOfWeek/

eventually you are lucky and theres a plugin on the marketplace which exposes those to BP

[barren kestrel]

@be thanks i will just have to try figure in bp i am not good wit hc++

[maiden wadi]

@barren kestrel Do you have the ability to even make a very basic C++ BlueprintFunctionLibrary?

The functions you're looking for already exist in engine. They're just not BP exposed.

.h

UFUNCTION(BlueprintPure)
static FText DateTimeToTextFull(const FDateTime& InDateTime);```
.cpp
```cpp
FText UAuthaerTextLibrary::DateTimeToTextFull(const FDateTime& InDateTime)
{
    return FText::AsDate(InDateTime, EDateTimeStyle::Full, FText::GetInvariantTimeZone());
}

[barren kestrel]

@maiden wadi thanks never attempted to do it but I should be able with your example thanks

[maiden wadi]

Good step to take. 😄 Even a library will open a lot of doors in the engine for you.

[trim matrix]

can someoen hlep me out with the eidtor utility widget? i feel sooo stupid cant make even a simple button to work the way i want to :( if anyone could help me on voice chat or knows a good tutorial i would really appreciate it

(basically i have a blueprint with bunch of objects, cameras and lights in it, and i want to make presets sorta say to work in editor, with a custom menu i make with editor utility widget, so when i click on option 1, everything except cube 1, point light 1 and cmera 1 gets invisible, same goes with option 2 and 3 and etc) on paper it seems easy but i cant seem to figure it out on my own and cant find any proper tutorial on it) an y helps would be highly apreaciated

[barren kestrel]

What exactly have you tried right now

[spark steppe]

now have fun figuring out the name of the day

[barren kestrel]

thanks guys It really helped I made the c++ function library as @maiden wadi showed and I also learned there is a AsDateTime node in BP that converts the result from the now/today nodes to text and calculating the day of week from there is easier

[maiden wadi]

Other downside to the BP approach is that you have to relocalize everything. Including the date format.

[trim matrix]

ok its really reallu stupid but i made just 2 set ups to be changed with boolean, it works on blueprint on its own, i wanted to see if i can make it work with buttons and unfourtinately it didnt

thats for utility

thats for the actual BP

[lofty rapids]

when does the construction script run ?

[trim matrix]

it...always?

whenevr i click on the boolean itself it works fine

when i bring the utility menue i made, it doesnt work

[trim matrix]

something here needs to change

[barren kestrel]

is your casting correct

[trim matrix]

what you eman by that?

[barren kestrel]

Did you create a variable and the assign it as your BP object refrence without casting or do you use a cast to node

[trim matrix]

without casting

[maiden wadi]

He means your BPReference in this picture. He's asking if it's valid. If it's setting the boolean correctly on the intended instance.

[barren kestrel]

then ithink most likely it is ot valid

[trim matrix]

i dont think its valid cuz its not working

[maiden wadi]

Chances are you need to set it to something. This is an editor utility, right?

[trim matrix]

yes

like set it to what?

you mean inside the BP itself right to set it?

[maiden wadi]

The instance you intend to alter.

[barren kestrel]

Yeah you need to get the parent of the BP when the menu starts then use that to cast to your actual BP and set that as the BP Object Ref

[maiden wadi]

You can usually use these to gather actors in an editor utility for example.

The left gets all of them, the right gathers what you have selected. If you loop over them and cast to your BP type, you can affect it that way.

[barren kestrel]

what @maiden wadi is saying works as well

[trim matrix]

my knowledge of blueprints is really really low, i genuinely cant fully understand what you mean, do you know any good tutorial to explain these on a beginner level?

[barren kestrel]

https://www.youtube.com/watch?v=DBIlsxj5quA

[deep yarrow]

If i want to ask a complicated question regarding some blueprint code i made, do i just ask it in here?

[maiden wadi]

For example. Replacing your button click code with this.

[maiden wadi]

Probably.

[lofty rapids]

a break would work well to cut down on the iterations if your only using one in that foreach

[trim matrix]

ok something really weird is happening

in the detail panel of the blueprint i see its working, its getting on and off

but nothing is changing to the actual object

wish i couls send a video to show it

[maiden wadi]

Construction scripts may not run editing properties this way.

[trim matrix]

like

[maiden wadi]

You could move the code in the script to another function and call it both after setting the bool in the editor utility and from the construction script.

[trim matrix]

this is getting ticke on and off

but the actual BP is not changing but when i manually tick it on and off then it changes

[maiden wadi]

Right

[maiden wadi]

Do this

[deep yarrow]

Ok. I have a video here where i am showing off the problem i have with my code:
https://youtu.be/GV2GrP3JZF8
I am working on a teleport system for a platformer game, but for some reason, the end location isn't in the correct place. The teleport system works where you can chain teleports while holding down left mouse button and pressing the WASD keys. When you press the keys after each other while holding down the mouse button, it adds the teleport locations to an array and when you let go of the mouse button, it loops through the array and teleports to the locations. The orbs that spawn are the teleport locations. The problem is that, the intended locations would be orthogonal to the player, and would simply be the previous teleport location plus 200 in the new teleport direction, but it doesn't end up in the correct placement.

[trim matrix]

you mean to movve this code into custom function?

[maiden wadi]

Right. And call that after changing the boolean and from the construction script.

Er

Sorry, no, not that.

[maiden wadi]

This code in this image.

[barren kestrel]

where does it end up

[deep yarrow]

Can you see the orbs in the video? those are the end locations for each teleport when i press a key

It seems to me like the previous location isn't added properly to the new location, but i don't know what to do about it since the math in the blueprint seems correct.

[barren kestrel]

okay do you have a snipet of the math

[lofty rapids]

the videos kind of long, normally if you can shorten things down to the problem area it helps

[deep yarrow]

The first part of the video should just show the problem with the teleports

I'll find a snippet of the code, 2 sec

The rest of the video just looked through the code and showed some solutions i tried

This should be the math part of the code

The input vector is just a vector that has either 1 or -1 in one of the coordinates and 0 in the other. The output list is looped through afterwards and then used as coordinates to teleport to

[lofty rapids]

i'm guessing you want them to go straigh in a line when w, then a/d move to the left/right of the one your on and wasd supposed to work like that ?

[deep yarrow]

If i understand you correctly then yes.

If you chained W and then D you should end 200 units in front and 200 units to the right of your starting location

You end closer to 100 units in front and 200 units to the right

The teleport distance variable is 200

[barren kestrel]

then you should add to the last teleport location rather than player location

w will give 200 units upfront then d will add 200 units right of w

[deep yarrow]

That is what i want

But it doesn't actually happen for some reason

At around 20 seconds in the video you can see the result of pressing w and then a

[barren kestrel]

if you press w and d the vector is not normalized its wont give perfect 1 on both x and y axis hence when multiplied by 200 it wont give perfect 200 distance

[deep yarrow]

I multiply the d vector and the w vector seperetly and add them together afterwards.

i first calculate the W vector, which is normalized, then multiply it by 200. That is stoed in a variable. Then next run through, i calculate the D vector in the same way, then multiply it by 200, then add the W vector afterwards

[lofty rapids]

that math is supposed to figure out if you want to go forward/right ?

oh i see if it's zero

then * 0 should just have it set to zero ?

[deep yarrow]

I don't think i understand what you're asking

At first i define a vector depending on the direction i want to go. Then i multiply the different coordinates with the corresponding direction vectors for the players rotation

That should just make a unit vector that is foward in terms of the player if i press w, and the other 2 vectors become zero, since i don't move along those axis

If that's what you're asking about

[barren kestrel]

none of these increase by 200 even in a straight line thats why i thought the vector might not be perfect 1 to multiply by 200 and give you 200 out

[trim matrix]

thank you so much it works, but for some reason i have to click the buttons twice to make it work properly first time clicking it changes it in details pannel and second time actually changes it, any idea why?

[deep yarrow]

They should increase by a vector of length 200

[trim matrix]

if needed can send a picture as well

nevermind fixed it

had to move it a bit further

[lofty rapids]

did you try using the last location instead of actor location like suggested ?

[deep yarrow]

What do you mean?

[trim matrix]

@barren kestrel @maiden wadi thank you guys soooooo much, if you guys ever needed help with textures/materials or anything related to environment design ill be more than happy to repay your kindness and help you out❤️

[deep yarrow]

Like instead of adding the last vector and then adding the actor location, simply adding the last location?

[lofty rapids]

also are you sure your inputs are comming in correctly ?

[deep yarrow]

Yes, i'm pretty sure, i have tried writing out the inputs and it seemd correct. Also the first teleport is always correct, so that should be right

I have also tried something where i instead of adding the last vector and the adding the location, i simply added the player location, and all the teleports went the correct amount in the correct directions. That method just doesn't actually think about where the last teleport ended, so it doesn't work to end up in the correct location

[broken gazelle]

Don't you just need to add forward, right or left vectors to the last orb location?

[deep yarrow]

Well, what i'm doing is adding forward right or left vectors to the relative position of the last orb, and then adding the location of the player afterwards, which should do the same

[broken gazelle]

Is this what X * forward vector is doing?

Should it be (x, 0, 0) * forward?

[deep yarrow]

I don't think i understand what you mean.

The forward vector is caluclated by doing x * forward vector, where x would be 1 for forward, -1 for backwards or 0 for sideways movement

I've now tried to set direction sum to the player postion when left click is first pressed down, and then not adding it to the vector afterwards, but it doesn't work correctly so i might have done it wrong. Now it simply ignores the previous teleport and instead just teleports relative to the player position both for the first and any consecutive teleports

The code looks like this now for the math:

And instead i added this to where the teleport is initiated:

Teleporting with A and then D now gives these 2 positions:

Where the ideal would be the left one is in the correct position but the right one would have ended at the player position

W then A looks like this:

[broken gazelle]

What does A W A W look like

[deep yarrow]

With the new code, it looks exactly the same

The new code doesn't care about the previous teleports

[broken gazelle]

You're setting the actor location as the diration sum

[deep yarrow]

I tried doing it do it only happende when i initially pressed right click

I thought that was what the "triggered" part of the block did

I don't know where else i could place it

[broken gazelle]

Maybe triggered isn't the right one

[deep yarrow]

Is there an if statement in blueprint code?

[broken gazelle]

Branch

[deep yarrow]

Then i can just make an if statement, and while inefficient, i could test out if this concept would work

[lofty rapids]

i also added a set last after the spawn

[deep yarrow]

I got it to do it in a way where it only sets the position initially, but now it just works in the same way is it initially did, when i added it to the sum of the vectors from before. W then D now looks like this:

So adding the location to the first teleport, and then adding the location of the previous teleport during the next teleports gives the same result as adding the relative location vector of the previous teleport to the new teleport and then adding the player position afterwards.

[lofty rapids]

i would just set the forward and right, add them together, multiply it by the distance you want to go, add that to the last location

[deep yarrow]

I'll try that

[lofty rapids]

in the example i used 0,0,0 as the default to mean it's starting and get the player position

so to reset it you just reset back to 0,0,0

maybe a better way that was just what worked

[deep yarrow]

So like this instead?

And then after a teleport, you just reset Diration sum to (0, 0, 0)?

This code just does the excact same result as my code from before

[lofty rapids]

^ this worked

[lofty rapids]

you probably want to set it after the multiply

[deep yarrow]

But then i would also multiply the new values

They would just get enormously big really quickly

[lofty rapids]

idk about the other value your using

[deep yarrow]

What other value?

The multiply?

[lofty rapids]

the sum

after you add the three together, multiply by the distance and that's your next location

set that as your last location

and just add the new to the last

[deep yarrow]

That was what i did in the beginning

[lofty rapids]

but you were using actor location each time

not the last location

[deep yarrow]

I was adding the relative last location, and then adding the actor location afterwards

This one here

Or i was just using the last location in this one:

They gave the same result, and the same result as the one i do now

[lofty rapids]

any reason you want to use the actor location+relative when you can just set the current, will he be moving during this or something ?

[deep yarrow]

He might be, as this could be happening while he is falling

But i did it the other way around before, and it had the same result

The way like the last 2 images, where i only get the location once at the beginning

[lofty rapids]

again this way works just fine

[deep yarrow]

But doesn't that do the exact same thing as my last one?

The message with 2 images

[lofty rapids]

well i tried with using the offset like your doing and i'm running into problems

[deep yarrow]

What offset?

[lofty rapids]

your dilation sum variable

what is that supposed to be ?

the last location is not the added values, but the location of the last spawned or the total after you add to last location

[deep yarrow]

Well that variable is for the first run through the position of the player, and for the next run through it is the position of the last teleport location

The weird thing about my problem is that if i simply print out the vectors, they all look correct, so if you're just printing them out they might look correct, but when i actually spawn the spheres and teleport, it isn't the correct locations

[lofty rapids]

it's not though because you didn't add from actor location

set the last location after spawn, or use the character to start off

[deep yarrow]

If you look at image no. 2 in my last message, you can see that i added the location of the character to the variable

There is missing a bit in the image but i made a branch so it only triggered when the diration sum is (0, 0, 0)

So when i first press down left mouse button, it sets diration sum to the location of the character. Then when i make a teleport, it sets the new diration sum to the old diration sum plus the new teleport vector

[broken gazelle]

Set diration sum after you add the new pos to the array

[deep yarrow]

That shouldn't make a difference, should it?

[broken gazelle]

Not sure but looks like it does

Since you first execute the set

And then the value changes

And the array execution computes it again with the new value

(I think?)

[deep yarrow]

It didn't seem to make a difference. The result looks like this:

And the code like this

[lofty rapids]

set the last position after the spawn
get the actor location and set it there

[deep yarrow]

What is the spawn?

Spawning the orbs?

[lofty rapids]

i had a problem setting it after the math was complete, so i just set after the spawn

[deep yarrow]

So i should get the location of the orb, and set that as the last location?

[lofty rapids]

yep

i would tone down the space a bit so you can test it out make sure it's accurate

[deep yarrow]

What do you mean tone down the space?

[lofty rapids]

i mean the distance between spheres

just make it a small amount so you can see it working kind of hard when it's spaced far out

[deep yarrow]

It's just easier to see if the difference is a bit bigger, but i can set it down to 100

It seems to be working now, after i started using the orb locations

I think this looks right. This was W, W, A, A and then i rotated the camera to look at the distance

Those seem about the same distance apart, right?

[lofty rapids]

i mean just test it out a few times, adjust the distance make sure it's all the same

you can really see it when you change it, make sure it scales properly

[deep yarrow]

I think the distance you move forward and the distance you move left isnt the same, but it seems like for moving one direction the distance is consistent

[lofty rapids]

well i mean look at your inputs

are they correct or changing for left/right up/down ?

also what does it look like now ?

[deep yarrow]

The inputs should be correct

The code looks like this now:

And the output ingame like this:

[lofty rapids]

i mean it looks ok, are you saying it's different left/right ?

[deep yarrow]

No, left/right is correct

I'm saying it looks like The amount for W/S is different from the amount for A/D

But it doesn't really matter

[lofty rapids]

looks fine to me, i don't notice it

[deep yarrow]

Since now it is actually consistent, this is a really good result

[lofty rapids]

you don't need the check for 0,0,0 if you always set it back to the actor location when you mouse down

that was just a way to keep it in function and working off the bat, didn't know you had code running that sort of "sets it up"

[deep yarrow]

I can see that it was probably just perspective, it seems like A/D is the same as W/S

[deep yarrow]

I need to set it to (0, 0, 0) since i use that to make sure it only sets it to the actor location when i initially press down left mouse button. Otherwise it just keeps resetting it to actor location as long as i hold down left mouse button

[lofty rapids]

whatever works

[deep yarrow]

Yeah

It works now, so i'm all happy

I was struggling with this for like an hour and a half earlier today with the friend i'm working with on this, where out teacher sat with us for about 15-30 mins of it

And we couldn't get it to work

So thanks a lot for the help

[barren kestrel]

I made my own version though basically the same in princple end i just finish to find yours working🤣

[deep yarrow]

Damn

But thanks for trying anyways 🙂

[pulsar geode]

Does anyone know how to get when a player is moving diagonally? Specifically diagonally relative to the first person player view.

[spark steppe]

might be dot product of forward vector and velocity

https://chortle.ccsu.edu/vectorlessons/vch09/vch09_6.html

close to 0.707 is diagonal

[burnt heath]

Hi everyone, I'm new to unreal and can't find how to make it work:

This is the fonction of my UI button and I'm trying to start the fonction "ChangeTexture" that is on a different actor (Sofa). it look like the reference is not working and I'm a little bit lost on how can I make the link between this button and the sofa "change Texture" fonction that is on the sofa actor (each sofa have the InteractMenu Component so I want them to all individually have their own menu)

[lofty rapids]

your trying to run that function and it's not working ?

[burnt heath]

yea pretty much

[lofty rapids]

the print string is happening ?

[burnt heath]

yea both work

[lofty rapids]

did you get the function from draggin out of the reference ?

[lofty rapids]

does that print happen ?

[burnt heath]

I don't think so, thats whats my problem, I don't think I know how to get the correct reference

[burnt heath]

nop

its definetly a reference problem

[lofty rapids]

how did you set the reference ?

[burnt heath]

tbh, I'm not sure a 100%, I was trying 20 different way since I wasn't sure how to do it but right now I think its just a variables created that have the variable type of the blueprint that have the fonction(I know it doesn't make sense)

sorry I think i'm not clear: how do we usually create a reference to a other blueprint to have acces to their fonctions (the fonctions would activate on the reference) for exemple here : I have a sofa that have a widget attach to it. I want to when I press that button, the button go on the sofa blueprint and activate the fonction change texture to switch his color

[lofty rapids]

i'm still new to unreal but i believe there is a couple ways

one way may be to get actor of class

[burnt heath]

omg I think I found it

I was getting it correctly but I wasn't getting the value

[lunar sleet]

Line trace usually

[lunar sleet]

That’s not always a good idea

[lunar sleet]

If you had another sofa to your game, that functionality will break

[burnt heath]

oh I see

if each sofa have their own widget , wouldn't work?

[lunar sleet]

Nope

It’ll get the first random sofa in the world

[burnt heath]

ahh I see

[lofty rapids]

maybe find the closest sofa

[lunar sleet]

Yeah

So use a line trace from your character and cast to the Sofa

This’ll also make sure your sofa is not in Africa

[burnt heath]

sorry I see Cast a lot but I don't understand exactly what it does

[lunar sleet]

And it’ll let you get a ref to that specific instance

[lunar sleet]

Take the time to watch the bp comms video pinned here

It’s a tad long but you’ll understand what cast does and all the other methods

[burnt heath]

oh wow thanks you, I will check that out for sure

I feel like finding unreal engine information to do anything is so hard (maybe beceause I'm not used to the vocabulary yet and I'm from unity)

[lunar sleet]

This place is prly the best place to find them. Along with the unreal learning portal

And MathewWadstein videos

[little pulsar]

how do make an arc trace be at the same place every time

[burnt heath]

good to know! will check that youtuber too

[lunar sleet]

Same place?

[little pulsar]

trying to make the arc ok the attack hit the same place evry time so the sword connect to the head everytime

[lunar sleet]

Could maybe put a collision box on the head and get its location and plug that in your trace, but it’ll need some testing

[little pulsar]

it did not work

[little pulsar]

found the problem and i fix it i think

[rancid oriole]

Is there any way to play a curve asset in timeline?

[ionic palm]

Would anyone have any recommendations on a better way to do this as my character gets punted half the time when exiting the sailing mode?

I think this is an issue with how the character interacts with my boat in general but is there a way to make sure the character is planted on the ground before I swap back from the pawn ship?

https://streamable.com/11s5d3

You can see what I mean here

[devout oak]

https://i.imgur.com/10mnILd.png

how would i write this in bp

[dawn gazelle]

Actually, probably not what you want, seeing as you likely have a structure of items that have a cost property.

[mental trellis]

That isn't what it's asking, though.

That sounds very much like a "I want you to do exactly this so you can show you know how to use loops and variables" type question.

[fiery glen]

looks like a task for a course

[zealous moth]

@dawn gazelle Create a function where using it on itself will return the negative of the original input.
Such that f(f(x)) = -x
E.g.: f(f(3)) = -3
or
f(f(-2)) = 2

You can use any programming functions at your disposal 😉

[eternal dirge]

how can i let the set velocity results in movement component to last for a period. Now I set the velocity it only appears for an instant.

[zealous moth]

@eternal dirge what are you setting velocity to? character? object? physics object? a car?

[eternal dirge]

player controlled character

[zealous moth]

if you use the movement component you can set the max walk speed

[eternal dirge]

Ummm. I just want to add some velocity to my character. Like in a velocity field, once you walk in to it, your character automatically get some static velocity beyond the movement input.

[zealous moth]

hm sec i got a way

ok, you know your movement input logic?

you can add that over a period of time

either on tick or a timer with high frequency

that mimics that

[devout oak]

Im unsure how to to put this into bp. I think ive gotten the rest of the code correct though
If Element.cost > curHighest.cost
Set curHighest to Element

[eternal dirge]

So, I cannot just set the base velocity for the character movement? But that's surely a way. Thank you, my friend.

[tawdry surge]

You can set velocity directly, but it'll be pushed back down in a few frames by the character movement component

[zealous moth]

yeah hence your best bet is to "add input" over X amount of time using tick or a timer or a timeline

[faint pasture]

CMC responds to force

Just add force based on velocity vs field velocity (if you're trying to do a conveyer belt thing

[dusky rain]

what could cause a timer to never ever fire, not even once? actor is set to tick, although I'm not even sure that's supposed to matter

never mind

[lunar sleet]

It doesn’t matter, that’s for event tick

[dusky rain]

yeah i thought so

my problem was my input action was repeating the input while holding, re-setting the timer every frame 😄

[lunar sleet]

Triggered pin has its own tick, so you would have to go off Started if you want to use a timer

[dusky rain]

i cant seem to figure out how to bind an action with enhanced input and detect pressed vs released

Started is meant to be called when the trigger has been started to evaluate, but not actually triggered yet

I read a suggestion about adding both triggers to the action, and then checking the value in the bound method

[lunar sleet]

No no

You leave your trigger on Down and run things off Started or Triggered and Completed

[dusky rain]

ok, ill go with that then

thanks

[zealous moth]

what's a good way to track time spent that isn't affected by frame rate?

Doing a race and I wanna record the time

[lunar sleet]

There’s 4 ways, one of them being get real time seconds

See this convo: #programmer-hangout message

[dense ingot]

How can i make it so for everytime the for loop spawn's the actor there is a delay right before so it doesn't all spawn as one big group

[jade lintel]

i use a custom for loop macro

its pretty simple to make

[lunar sleet]

That is disgusting lol

[lunar sleet]

Use Set Timer by event, make a custom event, put the spawn in it, then connect it to the timer using its delegate pin. You can set it to looping and increase an int on each loop. When your int reaches the right amount, clear and invalidate the timer by handle

[jade lintel]

Too complicated for a simple task

• you can use the macro elsewhere too

[remote meteor]

The macro is okay, but i will suggest making it with a break exec so you can control it atleast.

If we are making latent events, being able to control it is a big plus.

[remote meteor]

UtcNow()

To record start and end time

But pausing the game will have problem as this records real time.

Will need some additional calculation to support pausing.

But using delta time to calculate time is also fine

[modern radish]

what's the general workflow when I need my Level Blueprint or anyblueprint to wait for some data to be computed on another blueprint, like the GameInstance, for example?

[surreal peak]

Delegate in GameInstance, bind in AnotherBP. Broadcast when done.

[modern radish]

Ohh I think I read about that workflow, but I never implemented it

[surreal peak]

Also called EventDispatcher in BP

[modern radish]

so this will like only trigger once the action is done in the first BP?

[surreal peak]

You still need the reference to the instance that has the dispatcher to be able to bind

[surreal peak]

It triggers when you broadcast it

See it as a newsletter

[modern radish]

Even if the logic is attached to Event BeginPlay in the second BP?

I understand the concept, it's exactly what I need 😄 just haven't done it

[surreal peak]

If you can't be sure that the action isn't already done when the other BP binds, add a boolean to the GameInstance

Set the boolean to true when broadcasting

Other stuff can then ask if the Boolean is true

And if not bind to the delegate

[modern radish]

I have a boolean already, which enables when the logic is done

[surreal peak]

The create event needs to go into the other BP

Here you need to create an EventDispatcher

Bottom left below your functions and stuff

[modern radish]

ahh okay, missed that

[surreal peak]

Call = Broadcast

[modern radish]

and then in the first BP, what is required>

[surreal peak]

You want to Call the dispatcher

In the GameInstance

[modern radish]

Awesome

[surreal peak]

Correct

[steady night]

Hey guys ive got a weird issue when im building my project im getting 2 versions inside the folder a older version and the new version as a sub folder inside the old one ?
the build is succsessull>)
so weird
any advice on how to clean the slate or what to do ?

[surreal peak]

Now on the other side you get the GameInstance, check if the JSONParsed boolean is true or false, and then either call the function that you wanted to bind directly (if true) or bind the function to the dispatcher (if false)
