blueprint

[manic geode]

for example I found some tutorials about how to create the door

not sure which one i need and for buldable prop, or just anything will gonna work

[thin panther]

No you cant really just do anything, there are best practices, and also horrible ways to do things

[thorny glen]

Hey Guys,
I am having issue in my game with my mouse, It is not being captured anymore.

Here is my scenario,
I started my game, my player start walking and reach a point where he overlap with box, and UI will appear and I set "Input mode to UI and game", then I press some buttons in UI and then close the UI with remove from parent and I set "input mode to Game only" but now my character is not receive input from mouse anymore (means now mouse dragging is not working So my camera is not moving anymore, I can only move my camera when I click and hold left mouse button and drag.)

If anyone know how can I get my mouse working after setting input mode to game only then please let know.

[limber wing]

I love the idea of riddles

[urban compass]

hello all , is any one know how to auto save levels and when pressed continue in main menu loads the level that autosaved or any tutorial

[versed spruce]

How do i store data in a list and add all the data in the list together

Its so simple but seems impossible to do in blueprint

The lists data is added in real time is the problem. So data tables are useless

[trim matrix]

I'm not exactly Einstein or sure if it's suitable for what you want to achieve.

• But you could loop through an array if that's what you're looking for (using for each loop).
• Creating a variable "last result" which is value of the current index + last result, that stuff is set by the loop body.
• When the loop is completed you can use "last result" to do whatever you want with it.

perhaps I should create a visualization, that explanation was just to get an idea if I'm getting your question right + if I got the brain to answer it lol

[versed spruce]

The idea is i need it to add all the devices requesting power. Subtract that by available power and return the % performance its allowed to run at. If half the power is available 50% if there is more power then is being requested 100%. I got all of it coded except the part that adds all the devices power requests. I thought an array would work but couldnt figure it out

I need it to add all the values in the array together. And when a devices power draw is changed it had to update only its value in the array

I dont understand arrays enough to make it work

[icy dragon]

Array is just list of stuff of the same type

[versed spruce]

Right but when i drag out the array node there is no sum or add function

[icy dragon]

If anything data tables are pretty much static array of struct

[thin panther]

I dont see the issue here, cant you just for each and add the value into a variable?

[limber jacinth]

You will have to loop through the elements of the array and add them up.

[digital lantern]

Hey, I'm currently making a random item spawn system on 2 TargetPoint, except I have a problem, sometimes UE4 makes me spawn the same item twice and I don't want that to happen, how can I do that?

[versed spruce]

Like this? I didnt think this was right

Aw

[thin panther]

You dont need to get the value as the array element does that

You can just have an empty var and keep adding array element into it

[trim matrix]

Quick question if anyone knows :

• is there a way to get a reference to an asset by name ?
• similar to the open level by name node

[thin panther]

No

[trim matrix]

Time for a plugin

[versed spruce]

i was still looking at that

[thin panther]

Is there any particular reason you need to do this. Sounds a lot messier then other methods

[trim matrix]

Mh just playing around with some stuff. Basically importing a file and being able to reference it (rn, spawning a mesh)

[pine ledge]

Make 2 Array, 1 for "Things Not Spawn" and 1 for "Things already spawn". When spawning something, just remove from 1 to 2. Just randomize array 1

[trim matrix]

I noticed the "array element" output was not connected and got paranoid.

As brother-1 said, just connect "array element" directly to the plus input at the bottom

[digital lantern]

It's possible to make a short schema because I'm a beginner on UE4 and I still have a lot of gaps, please

[versed spruce]

I think i got it

The problem is i need this to fire every half second. So i need to find a way to reset the value before it recounts. I get just put a set 0 infront of the for loop?

[trim matrix]

you can connect "completed" to a set node for the "last value" and set it to 0.

That way it will start adding the stuff again and get an up to date version

[urban compass]

is any one know how to auto save levels and when pressed continue in main menu loads the level that autosaved or any tutorial

[digital lantern]

I'll try it, I'll come back to say if it works or not

[thin panther]

Auto save is just every x amount of time save whatever is needed

Save a variable that holds the last level, and make your continue button open that level

[versed spruce]

I connected right before exec to reset it and completed to push the update to the other devices and its working how i want now. Another part in the chain isnt working correctly however. but i appreciate the help. Ive spent the last two days trying to find a way to make it work. It doesn't seem efficient but it works now

[urban compass]

can i make that time for checkpoint and auto save for levels?

[thin panther]

Wdym

You can do it however you want

You just need to make a save system

However you want to trigger it is up to you

[thin panther]

Thats about as efficient as you get

Adding up a few numbers is not intensive

[urban compass]

@thin panther do you know any tutorial for this my brain is not working right now i would be appreciate

[trim matrix]

noice . What I noticed is that, since i tend to tank the amount of features when I create some systems,
creating some flowchart can be a good idea to get an overview what needs to work + how things are linked.

You can check Miro, free and good quality app

[thin panther]

I do not

[urban compass]

Thank you 🙂

[thin panther]

No problem, sorry i couldnt do anything on the tutorial front

[versed spruce]

Am i understanding how clamp works wrong. If the value coming in is above the max it is reduced to the max. Thats how it works right?

[thin panther]

Yes

[urban compass]

you dont need to be sorry thank you for everything mate 🙂

[versed spruce]

Well the team is just me. I have a staged strategy for what im trying to build. First step is a smart power grid but im new to blueprint so i have to learn 100 things first. Its going well tho

[trim matrix]

for the ''simple move to location'' node thats not on my main pawn but an enemy. What do I plug into the controller part? Does it NEED an AI controller for that?

[versed spruce]

oh lol, its working how i want it too. I forgot if you turn a 10W light above 10W on a power grid that only gives out 10W it doesn't get brighter

[manic geode]

Do I have to have a collision box on my door to make it open?

[versed spruce]

So i tried adding another light to make sure it scales and it doesnt.

Problem now is instead of adding together to 2 lights power draw its doing them separately

[manic geode]

What does that error mean?

[pine ledge]

It mean your Var is null and you trying to do something on that Var

[versed spruce]

it means the reference is bad

[manic geode]

Is it pointing to the wrong object?

[trim matrix]

not pointing at anything

[versed spruce]

No object i think

[trim matrix]

share the bp

[manic geode]

how

[versed spruce]

screen shot

[trim matrix]

🤔

is that even the right bp?

[manic geode]

thats the door

what is wrong with that?

👀

[versed spruce]

Figured my problem out i think

[trim matrix]

I dont think thats where the error is tho lol

[manic geode]

where else should I look?

[versed spruce]

click on the error where it says static mesh and see what opens

[trim matrix]

click on the error

[versed spruce]

"set static mesh"

[manic geode]

ah shi i already closed that box

[versed spruce]

Just rerun it

[manic geode]

darn

not interactable and not showing errors

[trim matrix]

its probably a bug where the reference goes missing

[thin panther]

Depends what youre trying to do

[manic geode]

Im trying to make a door like in Rust. You place it and then can interact

[trim matrix]

could do like an is is valid check so it wont give you the error

[manic geode]

no errors

is there any other ways to grab them

There

Where should i click

it says none

[versed spruce]

click any of them till it selects something

[manic geode]

there

👀

[versed spruce]

One of your references is pointing at nothing is the problem

What is build ghost set up too?

It looks like the problem

[manic geode]

Build Ghost is the green sillouette of the building block you are trying to place

[versed spruce]

I understand the intent but it isnt point at anything to tell it what to target

[manic geode]

👀

[versed spruce]

Go to its variables

Its set to point at a actor type. Not a specific actor

[manic geode]

Yes

because I have multiple actors

like walls , etc

[versed spruce]

I learnt this recently. Its very annoying how it works

you have to tell it to look for a specific actor that currently exists in the level. Which for your case sounds like it doesn't exist

[manic geode]

why? I have the door in the menu....

[versed spruce]

I dont know why it works this way. Its frankly stupid to me but its how it is

I dont know enough about components but i can show you how i solved it

[manic geode]

what should I fix? it works in the tutorial for some reason...

[versed spruce]

your problem is a bit more dynamic then mine

This is a button i made to turn on and dim my lights

you can see reference light and light_2

On the side where it says default value you can select a asset to tell it to target

but it doesn't let you do it in blueprint

this is the same button in the world. It lets you change its default value

I selected the lights you see and now it knows the specific light to target

Otherwise i get the error you were getting

There are a few other ways to get a valid target

If you dont care what one you are targeting which you might not in your case

You can use get actor of class

Which gets the first actor of its type it can find

[tawdry surge]

You should get comfortable with getting references without setting them directly in the level.
It works well in a few cases but most of the time you'll need it dynamically

[versed spruce]

They only ways i know to get them is as i showed. Cast to and get class

if you know more ways please do tell

its convoluted and ass

[tawdry surge]

Manager classes and ID variables are common
Traces, overlaps, and hits all return a reference as well

Event dispatchers are also helpful for interacting with multiple things like light switch to lights

[thin panther]

Yes but the issue here isnt an actor reference, its a reference to a component in the same blueprint

Thats a component variable

Which gets made automatically when you add the component

[tawdry surge]

To a component i don't see

[versed spruce]

I know overlap and event dispatchers. Which also need a reference to work themselves

[thin panther]

In fairness the component tab is not expanded

[versed spruce]

Well i haven't fucked with components yet. but if i was getting that error i would know that would fix it for me

[tawdry surge]

Overlap doesn't and dispatchers can be called from a global object like the game mode or controller

[versed spruce]

See i want more global objects. I haven't played with game modes yet

Do you know a way to make a actor be a global reference? Or a variable it has?

I looked up manager classes and ID variables and didn't find much. Maybe you could link a doc about it so i can find it?

[tawdry surge]

If you only have one you can do get actor of class
The game mode/state/instance, player controller ,player pawn, etc.. have global getter functions

The general jist is you make an actor class and make a custom event with an input for a reference to the objects you want it to manage. You then add that reference to a list and you pass the array index back to the object so it knows which reference is theirs.
Then in the object on begin play you can get actor of class for the manager and call the register event you made along with a variable to hold the ID (array index)

If the manager class is in charge of spawning the objects too then you can just register then on spawn and pass the index at the same time. All you need to do for that is make sure the id variable is marked instance editable and expose on spawn

[wicked osprey]

Guys, which type of shooting is expensive for a computer line traces or physical bullet? Can there be problems with physical bullet at low fps

[tawdry surge]

Line trace is way less expensive. Depends how many bullets and how low the fps

[versed spruce]

Im no expert but pretty sure shooting physics enabled bullets is much worse then invisible hit scan

[left fulcrum]

I got a weird thing happening where I get errors when adding the widget to the viewport if I don't cast to the controller, even though I am not using it for anything on begin play

Not really sure why but if I remove it, I start getting errors again

[trim matrix]

whats the error?

[left fulcrum]

It says accessed none trying to read property, and says the issue is when its triggering add to viewport

PIE: Error: Blueprint Runtime Error: "Accessed None trying to read property CallFunc_Create_ReturnValue". Blueprint: Human_Child Function: Execute Ubergraph Human Child Graph: EventGraph Node: Add to Viewport

[rose elbow]

anyone know why this is happening

can't connect it even though its from the playerbp

[versed spruce]

Its a classic problem

[tawdry surge]

Widgets are added to the viewport which is owned by the controller
By casting to the controller you are loading it into memory so the create widget function can find it. You could skip the cast and just plug the get player controller into the create widget node

[versed spruce]

Which is more performant: interfaces or event dispatchers?

[tawdry surge]

Basically identical
They work in opposite ways tho

[left fulcrum]

Thats what I had originally, I was using the get player controller but it wasnt working, I had to use the cast. I get the same error when I use the get player controller so I was worried maybe I was misunderstanding something. And its still adding the widget even though I am getting the error

[versed spruce]

My other question is in this set up. If the same device calls the interface again will it add to the array or replace its all variable. And how do i make it replace if it doesn't?

[versed spruce]

They seem about the same but was unsure. Thanks for the tips

[wanton galleon]

Hi, I'm looking for a way to solve that problem, but can't find one
I've a custom event "Fire" which is call and internally launch that PlayMontage. The problem is that I want to early exit animation when there is more action pending, the early exit works well, but it means that maybe 4 secondes later, I'll have the OnCompleted firing... When i'm in another call of this "Fire" event...
It is a way to solve this ? But for example stop the current execution of the event ?

[tawdry surge]

@versed sprucein that image it will replace it

If you want to add to it each time you need an add node from the array section

[versed spruce]

How do i know it works that way. To me it seems like it would make a new entry since it doesn't pass any identifying info

[tight schooner]

Compile your player BP, then try deleting and remaking that function call node in your screenshot

[tawdry surge]

Your making an array of 1 element and then looping through.
Every time it will make an array of 1 element and loop

Unless you save the array to a variable and add to it, it will just replace element 0 with the new value

[rose elbow]

omg as if it was that simple

thanks man

[versed spruce]

Oh shit, i plan to have many devices call the same interface. How do i make each unique device call them and replace their old entry but not effect others?

[tawdry surge]

It will only effect them and not the other instances

But if you interact with the same thing multiple times this set up will not add new elements to the array. It will just overwrite the first element

[versed spruce]

Yeah i need it to add a new for one each unique device calling it

[white elbow]

Is there a nice and simple function that turns world location into a pixel location on screen?

[tawdry surge]

Project world to screen

[white elbow]

thanks

[tawdry surge]

You wanna use add or add unique

You'll need to save the array to a variable though so you can reuse it

[wanton galleon]

#blueprint message
Nobody have an idea about that ? I'm quite stuck

[tawdry surge]

Are you stopping the montage?

Or "interrupting" it

[wanton galleon]

Stopping the montage

Don't pay attention to the commentary, tried to understand what's going on

It is branched on the normal sync execution pin of the animation montage

[faint pasture]

Do you have a need for physics-driven bullets?

Is that what you mean by physical bullet or are you talking more general, with a projectile that flies over time.

[tawdry surge]

I'm confused are you using an anim notify to trigger this?

Cuz if this is happening then the completed shouldn't still fire

[wanton galleon]

Yeah it is here

Branched on OnNotifyBegin and OnNotifyEnd

actually the Completed is not fired, but the OnInterrupted is fire, and then there is other loop pass in the delay thing

[tawdry surge]

Well then that sounds like it's working as intended
Not sure what you mean by "another loop pass in the delay"

[wanton galleon]

Ok I think I got it

I forgot to reset the "Listen for early exit"

[urban compass]

is any one know how to auto save levels and when pressed continue in main menu loads the level that autosaved or any tutorial i am stucked and i cant find any tutorial for autosave

[teal gull]

Hey, I have a question I can't figure out. I am trying to play a fire anim montage but it just does not work.
I have my slot

I have tried these 3 functions and does not work

tried this on the anim bp

the only one that works is but does not trigger notify events

[teal gull]

i have been playing with that too

[faint pasture]

You are playing your montage on DefaultSlot. You are then in the anim graph using MainSlot, which is not DefaultSLot

[teal gull]

forgot to change it back

doesnt play it

[granite pebble]

Hello I just joined I got a question if willing to answer

I have a float and i only want my HUD to show unless the float value is changed this means anything health up down air meter etc.

[faint pasture]

Do you mean you want the HUD to disappear when nothing is changing, like Dark Souls?

[icy dragon]

Have something that controls the main HUD widgets to hide them on demand.

[faint pasture]

And that thing should be the HUD class or some other wrapper

[granite pebble]

i am not sure a floatchanged node or something exists but I need it to be called on all changes of that float.

[versed spruce]

Do sequences wait for the chain to finish before firing the next in the list?

[icy dragon]

Why not change it when player is damaged or something event based?

If player is damaged (or healed), do the damage and at the same time show the health bar if hidden.

[dawn gazelle]

Sequences don't really wait... Everything will be executed in order though.

[granite pebble]

Here is my Update Health Function

this changes all values in the health bar

[versed spruce]

If sequence one takes a long time could that cause sequence 2 to finish before 1 does?

[icy dragon]

Sequence isn't affected by latent functions.

Delaying on Then 0 won't stall the execution of Then 1, and so on.

[versed spruce]

Looks good

Hmm alright, not really a sequence then. Just a fire order

[icy dragon]

Somewhere before You Died check, do the thing where you show the health bar.

Personally I'd have it as interface call, and the HUD class with implementable event of it show the health bar.

[granite pebble]

so in my UI Widget I have a Show Bar (XXXX) and Hide Bar (XXXX) Custom Events

Show health is connected btw

i think this impossible due to the fact the float is updating constantly waiting for a change in value A>B wouldn't necessarily work

[lime moat]

Anyone know if its possible to have a "set timer by function" ignore a paused game?

[junior hedge]

Why do your bps look like that lol

[faint pasture]

How does your health bar know that its value changed?

[junior hedge]

Just connect your hide health to the false and combine to event tick

If I understand you correctly

[faint pasture]

@granite pebbleAre you using binding or otherwise notifying the widget to update?

[teal gull]

flat nodes and electronic nodes

flat nodes is free

[junior hedge]

Ic

[granite pebble]

Current Health and Max Health floats drive the bars this is the binding

[faint pasture]

K so you're using a binding. IDK if bindings can call out or not, but that's an idea.

Otherwise, just notify something whenever HP is changed. You already have the HP change event.

[junior hedge]

@granite pebble what is calling out to do the show health event

[naive stag]

How can I do it so that the execution pin will wait until another execution pin gives signal. Or something like that. I’m trying to make a system where only by a timer will loop be able to do each loop body

[desert juniper]

timer by event

[naive stag]

Bruh

How do u think this will even work

[faint pasture]

I mean the binding itself could maybe choose whether or not to show/hide the widget

Not sure how capable bundings are, or if they're a real function.

[desert juniper]

exactly as i described?

[urban compass]

is any one know how to auto save levels and when pressed continue in main menu loads the level that autosaved or any tutorial i am stucked and i cant find any tutorial for autosave

[faint pasture]

it's not that simple

[urban compass]

how can i find a tutorial there is no tutorial about this and i got stucked i dont know what should i do

[faint pasture]

Is my name not a strong enough hint?

Start small, start by saving ONE thing, like the position of the player.

[tawdry surge]

If you learn how save games work it shouldn't be hard to load the last one you saved

[faint pasture]

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

[urban compass]

@faint pasture i dont need player position of player i just need save the level when continue pressed at main menu the level loads just this

[faint pasture]

Is the state of the things whithin the level saved or just what level they're on?

[urban compass]

i am really dont know how to do that really a noobie

[faint pasture]

Is it like Mario where it remembers what level you were on?

[urban compass]

yeah just remmembers which level i am

[faint pasture]

Same idea, you'd make a save game that only stores a reference or the name of the last level completed.

Read that documentation i linked

[urban compass]

yeah i need name a of the level just completed or the level just started

[tight schooner]

I don't know offhand. But if you need an alternative you can make a BP tick while paused and sort-of make a timer using the system time or something that isn't affected by time dilation.

[lime moat]

I'm using a button class which doesn't have options for BP tick while paused 😦

[urban compass]

i read that documents but i think thats only saves player name not the level of the player

[thin panther]

it does, you need to learn to adapt things to your needs

you wont find examples for every specific need of yours

it teaches you how to create and set up a save system, and the functions needed for saving and loading, it is up to your to figure out how to adapt that

you aint gonna be able to do much in the engine if you cannot learn how to adapt examples to your requirements

[urban compass]

this specific you mean every game does this its not a specific in every game when you press continue it will loads your last level

[thin panther]

not every game does this

point is

you need to learn to adapt things

if you cannot figure out how to change a save system to save a level name instead of a player name, then you should be learning more of the basics

[urban compass]

yeah your right i need to learn but this is the last part of the project you want me to go start learn from basics?

[thin panther]

it being the last part of the project has no bearing on this

no ones saying delete the project

im saying you need to learn how to adapt things to your need

if you arent wanting to preserve the exact state of the level, then saving only the level name, and making a button utilise that in your ui is fairly simple

[urban compass]

hmmm i think your right i dont know the basics i have to learn,
yeah its simple but i cant do that 🙂

[thin panther]

the only way is up my friend :)

i reccomend looking at various other examples of saving

then breaking down what you need to save

if its just to reopen a level, losing current progress in the level then you only really need to save 1 thing

otherwise you need to break it down a bit more into what is needed

[urban compass]

its just to reopen the level i mean player quits the game in last part of the level five if he backs to game and press continue player will play from start of the level

[faint pasture]

Yes that's easy. Just follow the doc I posted and go from there.

A rough outline

Main menu
Does savegame exist?
If so, read it, load that level
If not, you're on level 1

etc

On exit/back out
Make save game, fill it with the current level name/ref
Save it
Go back to main menu

[urban compass]

oh thank you let me try it i hope i can handle it

[glass stump]

How do I do this but make it choose a random target point out of a selection?

[faint pasture]

Somehow get your hands on an array of target point actors and get a random element

GetActorsOfClass(TargetPoint) -> GetRandom will do it

However you want to choose which actors to consider

[glass stump]

Ah, thank you, I'll try it out! :)

[hard lily]

Trying to add a inventory system to this game, Ive got it opening and displaying the cursor however it wont close after being opened and after exiting theres an error (Following a tutorial video went throught it 5 times so far everything looks same and no comments on it with a fix)

Anyone have any idea? xD

[prisma stag]

One thing that I did when I had this issue, was to just set the visibility of the widget. This works because when you not only hide the widget, but set the input mode to game only, you won't be able to click on it.

[glass stump]

Nice, this worked! :D Thanks! :D

[hard lily]

I dont want to be able to click on it though when Its not open? @prisma stag

[prisma stag]

Sorry, not being able to click on it is what it does.

[brittle raptor]

Potentially a silly question, can I filter by class when in a utility widget when doing get selected assets?

[tight schooner]

@brittle raptor out of curiosity I googled it and there's a node for that https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/EditorScripting/Utilities/Filter/FilterbyClass/

[teal viper]

is there where i can ask a question about widgets? cuz i rly need help with smthn asap

[frigid mesa]

I have a widget that I call 'get user widget object' on in the beginplay of an actor component on the same bp class, but it returns null unless I put a delay in front of it. Is this a lifecycle ordering thing where the actor component beginplay somehow fires before the component is actually ready?

[surreal peak]

#umg

[teal viper]

i mean it involves blueprints

[surreal peak]

Don't ask to ask then

Just post your question

[teal viper]

So im trying to have a black screen fade out on Begin Play

[surreal peak]

Could totally be that the widget component hasn't created the widget yet

Check if a delay 0 helps already

[teal viper]

so what I did was On BeginPlay, play the animation where a large blank black screen fades out

[surreal peak]

That's a frame delay

[teal viper]

works fine

[frigid mesa]

delay 0 works

[surreal peak]

Yeah then it's just the order

[teal viper]

but because the screen is overlapping other widget components like buttons and stuff

and is on top of them

i cant click them

[frigid mesa]

do I maybe need to put a fn on the actor component and call that from the main bps beginplay then?

if I don't want to use a delay

[surreal peak]

Communication between 2 components is not so nice in ue

[teal viper]

i suppose i could set the black screen's position off-screen once the animation ends

All I need is to have the black screen click-thru

do u know how I can do that

[surreal peak]

Fade to Black is usually done via post process or not

Which sits below the UI

[teal viper]

True

But what if i needed to know this for anything else

like how can u have a purely-decorative image

there has to be an option somewhere i just cant find it

[surreal peak]

Set the visibility of the widget to collapsed or hit test invisible once it's fully faded out

[frigid mesa]

ok if I put a 'event construct' node on the widget and log something maybe I can figure out the order? Think I'm on the right track? That the only reason 'get user widget object' would return null is if it hasn't been constructed yet?

I just don't want to use a delay and then have some weird race conditions

[teal viper]

I just checked where u said

[surreal peak]

I can't recall when it is constructed by the widget component

[teal viper]

There is a "No Hit" visibility option

Thank u ❤️

[surreal peak]

But if both components use BeginPlay

Then one will do it before the other

We only have one game thread after all

In CPP you can ask if an actor has begun play. Not sure about components

Either way, you could also try to let your actor tell the component about the widget

[frigid mesa]

I was under the impression that all things would be constructed before any beginplay, maybe the widget component's beginplay has to run before 'get user widget object' will work? I'm tilted... I'll debug it tomorrow since the delay works

thanks

[surreal peak]

Just check the CPP of the compoent

Component

And see where it creates the widget

[frigid mesa]

whats a good way to find the cpp for the widget component?

[surreal peak]

It's totally up to the programmer when they want to create the widget and BeginPlay makes a lot of sense

[frigid mesa]

I wish the docs directly linked to github lines or something

[surreal peak]

Easiest would be to have a solution for your project

But if it's BP only project then you would need to check GitHub I guess

[frigid mesa]

you mean visual studio solution?

[surreal peak]

Jop

[frigid mesa]

its a bp project but I do know enough cpp to maybe figure it out

the widget component is just the builtin thing added via the blueprint 'add component'

and I assigned it a widget bp class

[surreal peak]

Yeah

[frigid mesa]

alright thanks m8 I'll look into it tomorrow, i'm too annoyed now

[brittle raptor]

Thanks for checking, before asking I tried that along with several other methods, and what I tried didn’t work because it’s expecting an object and not an asset and so the asset says it’s class type is just “class” instead of what it actually is

[tight schooner]

@brittle raptor there appears to be another variation for actor references specifically... https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Utilities/Array/FilterArray/

But yeah I misread you

I thought you were selecting stuff in the level editor

Idk about editing assets outside of the uh, batch editor thingy

[brittle raptor]

No worries, It's an issue I've never run into

[frigid mesa]

couldn't help myself, yea the widgets object is constructed in beginplay so its just a beginplay ordering issue

Ok so I'm designing an inventory system for my FPS game similar to Destiny where you have a "current weapon" "Stowed Weapon" and a "utility" which is just a combat knife that the player can never drop and has infinite ammo. I have a master weapon class "BP_Weapon" and I intend on using object references to refer to the children (the individual weapons).

My questions is how would I best setup the containers "Current Weapon", "Stowed Weapon" and "Utility"? Would I use a data structure? Actor component that has it's own inventory system? A Set of variables on the character?

[trim matrix]

wtf is this node?

[cedar remnant]

Anyone have any ideas. Anything welcome

[trim matrix]

Can have an array of BP_Weapon object references called EquipedWeapons. This array can have 3 indexes.
Index 0: holds reference to primary weapon
Index 1: holds reference to seconday weapon
Index 2: holds reference to utility weapon

each index is where you will store a reference to that equiped weapon

You can then have an intiger variable called CurrentWeapon. This int will keep track of which weapon is active.

If CurrentWeapon == 0, that means you are holding the primary. etc

when you press Y, check the value of CurrentWeapon. and switch to the correct weapon.

I suggest using an array to store weapon references because later on in your game, you may want to add more weapon slots. Using an array now will make that easier later.

You could use a map as well.

[tight schooner]

I'm hesitant to brainstorm cuz I never made such a system... But if you want an top-of-head idea... If you had a custom struct that represented all possible data about a weapon (class, ammo count, is loaded with ammo, has these mods attached, whatever else) then you can represent the weapon inventory as an array, and this array can go into Game Instance or a savegame etc for carrying it between level loads. I'm sure if you Google you'll find a million examples of actually functional UE4 inventory systems to take some inspiration from...

Cuz you're just making a thing that has fixed slots and limited complexity, a lot of different approaches can work

[trim matrix]

Yes there is a billion ways to do what you are asking.

[tight schooner]

(I guess total ammo count would necessarily be a separate array if you're doing it boomer shooter style)

@limber parcel What's your opinion on what to do in my situation?

[limber parcel]

like i said before, make a solid plan for game, find some friends who like your idea and have skills to make it happen, then you can start making a company (preferable outside of argentinia, russia, north korea etc...) and take ur game to kickstarter

if you make models and animations its always good to have something to show off to convince people to join u

[limber parcel]

guess best way to go would be starting a modding community around some popular game to find talented people

[cedar remnant]

So this event exists on my player character. On "Begin play" I attempt to set the inventory of my player character by passing in children of my Parent "BP_WeaponBase" into the "Equipped Weapon Array" where I then get index 0 (what I want my equipped weapon to be) and attempt to equip it. Problem is i'm not getting anything out. I tried printing my "Equipped Weapon array" but nothing happens.

Is it possible to store child_BPs (Such as a weapon) as an object reference on a character and then give them to a player?

[mental trellis]

try using breakpoints and see where the data gets lost

[mental trellis]

You can always send them crypto. You lose a bit in the conversion, sure, but still.

[limber parcel]

you lose more in crypto than in normal transfers in most cases

[trim matrix]

can I somehow keep the original array ive made so when I add or remove indexes I can still have an original copy? Do I just make it another variable?

[limber parcel]

yes just save it to a variable on start

But it will work pretty much anywhere to anywhere.

I get paid via wise

add variable

[trim matrix]

im being dumb lol

drag it out and select set

yea yea I get that lol

but the array starts empty

stuff gets added in a loop

[limber parcel]

then save it when the loop is completed

like this? lol

[limber parcel]

exactly

[trim matrix]

so messy

oh well

[limber parcel]

you can get another copy of that var if you dont like the spaghetti

[trim matrix]

yea but how? its in a loop tho?

[limber parcel]

its basically just a reference

btw ure working on same shit as me rn xD

btw, if you cast to a parent class it all the children can go into it?

ah nice!

[limber parcel]

no

[trim matrix]

im not sure what append and to array does tho lol

[limber parcel]

if you cast to a base class then u can only access the information thats in the base class

[trim matrix]

but what if I cast to the parent class?

[limber parcel]

i meant parent class not base class

[trim matrix]

oh

hm

thats annoying

I guess ill just use BPI's

[limber parcel]

the parent has no access to information stored in its children

but children can access all in their parents class

its like reverse parental control lol

[trim matrix]

thats what I meant tho, if I have a parent class called enemy with a speed stat, if I plug in a child class like idk. fucking goblin or something. Can I acces the speed stat

oh why bother bpi's probably work better lol

[limber parcel]

yeah basically u want to avoid casting at all cost lol

[trim matrix]

wuuut

mind blown thats cool as fuck

[trim matrix]

lol

[tawdry surge]

You do not want to avoid casting at all cost, that's a fundamental misunderstanding of why cast can be a problem
Second unless there is a significant difference in the way enemy types behave, the functions, and variables then you do not need different classes.

[limber parcel]

then where would i use casting (except for things where you have no other choice) instead of using an interface, component or delegate?

[tawdry surge]

If I know the object exists, and if I have only one specific thing I want to talk to are the main situations

Passing a hard object reference through an interface is actually worse then casting
Components are good for encapsulating specific functionality but making a communication component is a lil dumb since the point is plug and play functionality. Making them dependant on other components sorta ruins the design concept a bit

[trim matrix]

does array length 0 means the array is empty or it has 1 in it?

[tawdry surge]

Empty

[trim matrix]

hm odd

did I do something wrong?

I feel like it should work

but it ends after 2 loops

theres 3 in the array im sure

nvm it works fine lmao

[manic viper]

From within a component, can you get the "Event hit" of the parent without putting code inside the parent blueprint ?

[trim matrix]

Is there a way to make only one socket change rotation?

For example, head turning

[tawdry surge]

@manic viper you can "bind on hit" and plug in a reference to the owning actor

[manic viper]

Thats the path I thought, but I must be doing it wrong cause its not triggering I'll mess around more down that route

thank you so much

[gentle urchin]

Yes you can, since goblin would be an extension of your enemy class

Thus it inherits all functionality and variables the parent has

You dont need to cast to the parent class either ^^

Since we're already lower on the inheritance tree:p

[wintry geyser]

Also Casting isn't bad, it's just badly used. But that really goes with any way you can call something. Know when and how to set references, how often, and which type of calls are best for which scenario. Doesn't mean Casting itself is bad just because someone wants to cast at the beginning of an event tick 🤣

[tawdry surge]

Interface call on tick isn't any better either

[gentle urchin]

The workarounds are usually worse

Atleast those i've seen

[gentle urchin]

Then again like 80% of the tutorials spread this false information so no wonder people think its true

[gentle urchin]

Thats some next level flow control

[wintry geyser]

I do everything on event tick with sequences

[gentle urchin]

No timelines on tick? Sad

[wintry geyser]

I never write Functions, because then I can't use Flip Flop or Delay. Always use Delayed Flip Flops

[gentle urchin]

Or nested loops with getAllActorsOfClass

Id hate reading that blueprint😅

[fiery swallow]

The best one so far

[wintry geyser]

Don't even, I saw that too lol

[gentle urchin]

Holy damn

[junior hedge]

Hi neon

My agent is cooler though

[manic viper]

ok so the next step, is whats the best way to get the linear velocity of an owner component from the actor component. Ideally this thing should be able to be put on any object with a mesh

[gentle urchin]

Owner componemt of actor component? What?

[manic viper]

lol

sorry terrible phrasing

i created a blueprint to integrate FMOD audio events to get dynamic audio and physics based impact sounds and sliding/rolling

i am trying to convert that to an actor component that I can place on any physics actor in the world

[tawdry surge]

@wintry geyser you know macros allow latency (aka delays) and a flip flop is just a banch that sets its own condition to the opposite of the pin that last fired (true sets false->false sets true)

[manic viper]

so right now inside of the component, I get the owner actor, set it as a variable and then bind to the owners on hit event. Then I run my code in there. the problelm is, when I created the blueprint I was doing it ON an actor to test.

[tight schooner]

@fiery swallow https://blueprintsfromhell.tumblr.com/

[wintry geyser]

@tawdry surge I know it was a joke

[manic viper]

So im trying to figure out how to get the linear velocity of the components parent.

[tawdry surge]

Just checking

[gentle urchin]

Im still A wee bit confused. Why wouldnt this still work , binding to the owning actor?

[fiery swallow]

Lies

[manic viper]

because linear velocity needs a primitive component object reference

and im trying to build this component without being attached to anything so that I can drag and drop it onto whatever we need.

https://i.imgur.com/Hy8Jj7s.png

this is my current attempt at figuring it out

[gentle urchin]

Ohh

You could add the primitive component dynamically ^^

But maybe that defeats the purpose

[tight schooner]

Does the hit event struct contain the impacted components?

[manic viper]

omfg

of course it does

[mental trellis]

This actually looks like a weapon effect.

[manic viper]

oh BUT i alraedy have the owner actor

it doesn't have the self component, just what it hit

the hit struct contains the actor but not the component

hmm and its actually NOT tracking the hit impulse

from the parent

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

disregard that last part. I'm dumb and forgot to generate hit events off the simulation. But the linear velocity is still iffy

[fiery swallow]

The first one took me out
Someone should make a top 10 blueprint meme list

Event tick -> get all actors of class (actor) -> destroy actor 👍

[gentle urchin]

That one would be over really fast :p

[manic viper]

I figured it out. Thank you @tawdry surge for leading me down the right path!

I finally have a component that i can place on any object to simulate physical impact noises and sliiding + rolling sounds

( with Fmod integration)

I'm trying to randomly generate a 64-bit integer, but it seems to always return zero, but I can't seem to figure out what is causing it. The given range is between -9223372036854775808 and 9223372036854775807

[icy dragon]

Use this but randomly multiply by -1 or 1

[maiden wadi]

So. Fun fact. The Randomization code for integers is... interesting. Suffice to say, it doesn't really handle negative mins very well Also generally try to avoid using the upper limits of ints by a couple points. You're usually much better off just getting a random positive integer and as Makoto said, randomly multiplying it by -1 or not.

Amusingly, It handles floats really well. 😄

[civic notch]

Fair enough. Is there a specific reason why unreal struggles with this?

[maiden wadi]

Ancient code most likely. Never updated. Possibly never will be due to a few factors. First anyone who needs it on a scalable level just makes their own. Second is that it is used on older projects that would break if it's changed and Epic isn't going to deal with that fallout.

[civic notch]

Seems fair enough. I could probably write it myself in c++ instead then, seeing as it seems to be a bit unreliable

[forest crater]

Hey, I got a couple of questions:

1. Is casting on Begin Play and saving the cast to a variable, and then using it as needed more efficient than casting each time? Or is this the same action, just shorter?
2. Interfaces are better than casting, but realistically, how much should casting be avoided? Like is there any good practice to differentiate when to cast, and when to use an interface?

[tawdry surge]

1.) Yes saving and reusing is better then casting or interface everytime.
2.) Interfaces are different not necessarily better then casting. There plenty of situations where casting is better then interface and vice versa.

Use casting when you know the other actor exists and you only want to talk to one specific thing

Use an interface when you want to talk to one of many things or the object may not be loaded

Use a dispatcher when I want one thing to talk to many

[forest crater]

Nicely explained, thank you so much!

Have you tried just using instance editable variables marked expose on spawn? You can just pass the values you want on construction that way

[faint pasture]

Spawn actor

[cedar remnant]

Won’t that just spawn it into the world? I’m trying to equip it to my player character and his inventory

[faint pasture]

Good luck creating an ACTOR that's not in a world.

Actor being exactly the thing that's not letting you do what you're trying to do.

[limber parcel]

why dont you just spawn it?

[tawdry surge]

You can spawn and attach an actor in the world
You can add a component or just reassign the settings on a component you made on the player character

[cedar remnant]

Hmm

[limber parcel]

you can literally just do this

[cedar remnant]

Right but it needs a transform

[limber parcel]

just make a new transform then

[kindred remnant]

Hey people, in my level i walk into a trigger box, I have to press E and i've got some level sequences happening. Do you know how i'd activate a Post Processing Volume to start when I press E?

[limber parcel]

its just this

[cedar remnant]

So it won’t look stupid when the weapon flies from across the map at 0,0,0 and then attaches to a specified bone on my player?

[lucid current]

but I want to make it spawn a lot and walked along with my zone graph 🥲

[cedar remnant]

Hmm

[tawdry surge]

@cedar remnant spawn it at the transform of the socket on the player you plan to attach it to

[lucid current]

may i know where is the instance editable variables locate ?? im sorry this is my second day using ue5 and blueprint im not so sure about all these things

[cedar remnant]

Yeah ok

Just seem janky 😭

[tawdry surge]

Click on the variable
Its the 3rd option down in the details panel

@cedar remnant well I have a component on my character and just assign the mesh and values I want when I equip/unequip a weapon

[unreal marten]

is there a way to handle movement that allows for full collision without removing the scene root of an actor?

[foggy escarp]

You can add a collision shape without setting it to the root mesh.

[lucid current]

this is what i mean,,, is there anyway i can just let my character appear without clicking the play/simulate button ?

[foggy escarp]

You can simply add it to the level

Search for it in the place actors panel or just drag it from the browser

[lucid current]

but add it to level i have to one by one and add keyframe for all my character...

[trim matrix]

whenever I set the player pawn transform it doesnt work and just faces where the camera is facing?

Any ideas?

[unreal marten]

you can but floating pawn movement only checks collision on the root, same with interp to movement

[foggy escarp]

What's your limitations with not being able to change the root?

[cedar remnant]

So you made a separate actor component that handles your inventory?

[tawdry surge]

Physics collision uses the collision of the root
You can use set location and get sweep results to deal with collision instead if you want

[foggy escarp]

Your setting the world rotation here.
What's your intended result?

[unreal marten]

its 2d game using flipbook for the model, if I set the flipbook to the root then collision works fine but it makes any sort of rotation tedious as I have to account for the initial rotation of flipbook (can't find a way to bake in a starting rotation) and then any changes I make to the flipbook like scaling will affect anything attached

[trim matrix]

@foggy escarpchange the pc's location and rotation for a turn based battle style

[foggy escarp]

You mean orientated where it's walking?

[trim matrix]

no like stationary

just facing a certain direction

but its stuck on where the camera is facing

i guess theres a setting to not follow camera rotation?

[foggy escarp]

There's a node to get look at rotation. You can use this and plug it into the transform

[trim matrix]

i mean it should just be 0

[foggy escarp]

This would spawn it facing the right direction

[trim matrix]

cause thats what I said its transform too

but something overrides it

[tawdry surge]

@cedar remnant you could do that, but I was just talking about the equipped items' mesh and properties.
For the weapon, if the player will always have one, I would just have a skeletal mesh or static mesh component. Then swap the mesh and any other values I want.
For general items or if the weapon is more dynamic, I'd probably spawn them in the world and attach simply because if I drop or throw them it's easier to handle.
As for the inventory itself, you can just have a datatable of all weapons and their related base info. Mesh, attributes, etc.. and then make an array or struct to hold the ones that the player has. Whether you wanna encapsulate that in a component or if you want to build it into the player character class is up to you

[kindred remnant]

Hello - i'm trying to get a post processing volume to start on a button input. I want it to look like this - https://gyazo.com/d478e71e1a4e24b00de3a8635889a62b

However mine looks like this https://gyazo.com/c19d01ed791cefa1de8c418c9064558d and I can't get the "target" node to appear. Anyone know where i've gone wrong here and could help please?

[cedar remnant]

If I'm already handling the properties such as ammo count, fire rate, fire type (auto semi auto) inside of my parent BP_BaseWeapon and then adjusting those values on the child, I don't need the database do I? Is that what you were using the database for?

The rest makes sense thank you

[tawdry surge]

@unreal marten you can set the scale to use absolute world instead of relative and that will stop things from scaling with the parent.
Also you can get the class defaults value. In 2d you're usually at 0 or 90 to start so you could just hard code that as a constant or save it on start and use it for whatever you need

[unreal marten]

Id still recommend the datatable, it'll be easier to track and supply the stats for each gun.

[strange pike]

interesting question: is it possible to set casts initially as pure in editor settings? 🤔

[tawdry surge]

@cedar remnant I use the datatables for storing all the default properties so when I spawn a new one I have those to plug in
Then the item would handle it's own data from there.

[unreal marten]

experimental, default to using pure cast nodes

[tawdry surge]

This is because I don't have 30 weapon classes. I have more general classes and pass in the data I need to make it work for the one I want

[faint pasture]

I would use SOMETHING with collision as the root for anything meant to have collision

[strange pike]

thank you

[limber parcel]

and what u did before doesnt? xD

[limber parcel]

you can set the default data in blueprint

[cedar remnant]

That's fair I'm just trying for best practices

[tawdry surge]

That's gonna be more of a case by case thing.
You wanna shoot for having as little extra data loaded as possible and keeping things as self contained and independent as you can.
Static data like tables and assets and BP structs are cheaper to hold, pass around, and access, but not as great for data that you plan to change. So for your example current ammo count would be a variable on the weapon. Clip size, or max ammo count would be static data

[limber parcel]

what about actor components?

i use them alot

i put all the health and stuff into an actor component because its easy to access

no casting or interface required

and if ure lazy to make the nodes u can set up a macro

for each component

[teal talon]

Use just the head of the skeleton mesh by hiding all other bones.

[limber parcel]

just hide all bones and then un-hide the head?

[teal talon]

Hmm, Does it need a delay to next tick or can I hide unhide in same tick. I tried this but must have done it wrong.

Thank you for feedback

[limber parcel]

i messed with that today, i had to make an abomination to get it to work

[limber parcel]

this

[glass stump]

how do I get everything, pretty much, in the level to reset after the character respawns?

[trim matrix]

use the reset node

[glass stump]

ah, thank you! :)

[lime yoke]

Hey guys, I'm kinda stuck here. My character blueprint has attached an actor of a sign (first picture). It looks good here. The problem appears when I rotate the character (Second picture).
What I want is to keep the sign on the same location despite the character rotating.

[tawdry surge]

What do you want it to do?
Cuz if its attached then it's generally gonna move with you

[lime yoke]

Found it. The solution was create an arrow component and put there the sign.

It flickers a little bit when moving, but that's a problem for another day.

[glass stump]

Is there a way to use the 'Reset Level' node that doesn't cause spawned PlayerCharacter actors to get deleted?

[shy yew]

Hello, I have a big problem on a program and I can't find out where it comes from.
The goal of the program is to generate a maze. The tour of the wall is done correctly, the problem is what comes after, I have the impression that half the time the program thinks that a vector is not in the array whereas it is there. The problem is that walls are built where they should not and block the passage (which is annoying for a labyrinth).
If you can see where my mistake is I would be extremely grateful.

[faint pasture]

Same RELATIVE location or same WORLD location?

If it's world location..... just don't attach it?

[shy yew]

Which gives this:

[amber hill]

Guys, Does anyone know how large of a plane you can make UE5s water system to have as much effect on low performance as possible ?

Open question I know

[hot ibex]

does it loop without the condition ?

[shy yew]

me ?

[hot ibex]

No Hamilton sorry^^'
without the Charge value increment

[white elbow]

I just forgot to change the timeline length lol, sorry abt that

works as intended now

[hot ibex]

oh right it was you

the pic disappeared haha

[white elbow]

How do I make a progress bar that fills with rectangles, like this?

[hot ibex]

I'd say with an HUD component and a loop

[white elbow]

I've only found a percentage progress bar

[tawdry surge]

If you look in Lyra they have this type of thing for the player health bars. Its way more involved then a simple progress bar tho

[hot ibex]

Hey ! I have a problem with something that worked on UE4 and doesn't on UE5

Basically, I can't make an Interface Array to reference actors anymore, here is a very simple case :

• Two kind of Door actors, implementing a "Door" Interface (so they get the same Open event)
• A button that contains (as variable) an array of these Doors (so i know which targets which)

In order to target both kind of Doors, the Button's variable isn't a Door array but a Door Interface array, so I can reference all actors that implement this Interface with no additional check nodes

It works fine on UE4 and absolutely not in UE5 ,
it'll work if a use an array of Doors, or generic actor but not interface

[trim matrix]

U think I can give a decal projector some movement?

[faint pasture]

Start with a material that can be driven by a parameter

[faint pasture]

For example this is from our WIP UI, the bar material just has parameters for number of divisions and value

You need to get comfy with thinking in UV and think about how the material knows what color to output based on UVs.
In our case, we choose which color based on distance from the segment divider. Something like:

if Abs(Pixel.U - Round(Pixel.U * 4)/4) > 0.01, choose one color, otherwise choose the other

[glass stump]

Is there a node where it like exempts a particular actor from an event?

[faint pasture]

What are you trying to do?

[hot ibex]

are you in a loop ?

[glass stump]

I've set up a system whereby my player respawns when it dies, however the enemies and items in the game stay the same as when the player died, but I want them to reset.

So I'm using 'Reset Level' because if I restart the level completely it won't save checkpoints.

I assume.

Unless I create a save system.

[faint pasture]

Save Checkpoints in a savegame or GameInstance

if you want ResetLevel to be how you reset the level

[glass stump]

are there other ways?

[faint pasture]

I mean you can manually have everything to back to how it was on begin play but that'd be a lot more work

[glass stump]

performance-wise it'd be worse do you think?

[faint pasture]

Depends, don't worry about perf right now

IDK if resetlevel does a full nuke and reload or not

[white elbow]

make a rectangle of some sort and repeat its texture as many times as I need? that's the only thing that comes to mind besides making separate rectangles and turning them on/off separately

[glass stump]

Ah, okay, well thank you I'll look into this and see what I can do. :)

[faint pasture]

Yeah he could do this too, have the segments be in a texture and just progressbar the texture. A million ways to tackle this.

[faint pasture]

Does ResetLevel happen pretty fast right now? I've never used it.

[glass stump]

yeah it seems to be pretty fast. i was just trying to out now and really the only problem with it is it also deletes spawned player characters for some reason.

[faint pasture]

The reason is that it resets everything. IDK if there's a way to keep the character from being reset other than using a multi-level approach

You have a persistent level the character is in, then can reset the streamed level

[glass stump]

Yeah I was thinking about that too. I thought Level streaming might be the way to do it, but thought it might be a lot of work to go back and separate levels into multiple levels, but if it's the best way it might be worth it.

[faint pasture]

I'd at least experiment with it but it all depends on what you wanna do really

[glass stump]

I think I'm just trying to find a shortcut to avoid having to use a save system. XD I've tried to implement one multiple times but can't seem to get it to work, didn't realise it's be so complex and should've started it right at the beginning of making the game, now I guess it's too complicated haha.

[faint pasture]

What all would you need to save?

[glass stump]

hmmm, mainly the Current level, Checkpoints (or just PlayerTransform I guess), variables saying which switches are on and off.

I wrote a list somewhere.... maybe i can find it

[faint pasture]

So Dark Souls style

[glass stump]

Yeah, I guess so.

[faint pasture]

Yeah that'd be easy. Just make a struct with all the info you need then make a savegame with that struct in it and you're in business

Save on death, load on restart

[glass stump]

Would that also save this if the player exits the game and comes back? (doesn't matter if not just curious)
But thank you so much, I'll try this out and see if I can finally get this to work! XD It's probably way simpler than I'm making it....

[faint pasture]

Start with making a Save and Load function and trigger them with buttons to test

Save, change stuff, Load, see what happens

then incorperate reloading the level on another button

then tie it all together with exiting and dying etc

[broken geyser]

Hi there, is it possible to spawn actors in editor (not runtime)? I know that there's a EditorBlueprint or you could set a "Run in Editor" flag but that doesn't work if I spawn an actor in a construction script via Blueprint or C++

[glass stump]

ah, thank you!! i'll give it a go! :)

[fiery swallow]

There's a lot a lot of ways you can do this, you would need to be more specific on what you want. Because if you just want it to simply fill up with squares then you'd just need to create an image with a bunch of squares and then set it as the fill image.

[tawdry surge]

@broken geyser afaik you can't spawn actors from the construction script.
You can for sure spawn components though

[broken geyser]

@tawdry surge Thats Ok for me, but my question is, is it possible to spawn actors during designtime? I need this for procedural level generation in editor

[autumn comet]

Hey, is there a way to construct or preload an actor that I can tweak its variables on runtime and then make instances of that preloaded actor later? Construct Object from Class doesn't seem to do that

[tawdry surge]

@broken geyser Ok, cuz you said the only problem with the two methods you listed was they don't work if you try to spawn in the construction script

[broken geyser]

@autumn comet Looks like a prototype factory pattern. Why not just spawn an actor (hidden) change the properties to what you want and call a custom "Copy" function. This function spawns a new actor with all properties from the prototype actor

[autumn comet]

prototype factory pattern? Is that a specific thing?

and when an actor is spawned I need their veriables to be tweaked before beginplay or tick events are triggered

which seems to happen even if I try to set their variables right after I use the spawn actor from class node

[broken geyser]

You can expose properties for construction script if you want, depends on the properties you want to change

[tawdry surge]

Yeah expose on spawn and then use those values in the construction script

[autumn comet]

I've never used the construction script of an actor before, I guess I'll look it up to see if it does what I want then. I need it for stuff like an explosion instance that I need its damage to scale with the exploding actor's damage before it can collide with an enemy

[broken geyser]

Sorry, Properties which are set "Expose on spawn" will be visible on a "Spawn Actor From Class" Node

[autumn comet]

ooooooh that's exactly what I needed! I just saw it

[broken geyser]

Ok, that means you don't have to preload or spawn an hidden actor, you just have to expose all properties for spawning and set it directly. Should do the trick for you?

[autumn comet]

yeye, thanks for the help!

[crude iron]

Does anyone know why finding an item in a text array won't work? Didn't have issues with this until upgrading to 4.27.

https://gyazo.com/1aec564e0c506b231db7e48041ff13f0

[cyan bone]

Also, how do i detect collision with a lerp? Should i check every lerp iteration if im overlapping someone?

[paper galleon]

I'm guessing that entry is not in the array then. Have you printed the contents and confirmed that the test you want is actually in the array.

[crude iron]

https://gyazo.com/91cd390333857dcb2f1de40683b92e4f

https://gyazo.com/1df100e1ccb13d7432e5ff471ec55bcf

Yeah it's there

[hot ibex]

🆙 , any ideas how to reference actors by interface in a blueprint array variable in UE5 ?

[dawn gazelle]

This bit here looks like you're trying to use a name to find the "ID" of the option. Using the resolution as the "name" of an ID doesn't make much sense to me.

Nevermind, I see it now... Just a bit confusing.

[crude iron]

I'm essentially creating a custom option box

[dawn gazelle]

Yeah, what happens if you print out the contents of the "Options" array?

[crude iron]

https://gyazo.com/8e8f38db38e106daa92fd524b72c203b

[teal talon]

Question: Hide all bones then unhide head doesn't work: What am I doing wrong. I even setup a bp just to test this and the head doesn't show up on unhide. I've tried root too, and neck_01 the entire mesh stays hidden. I Tried it will scaling all the bones too but I can't scale the body without it effecting the head.

[astral stratus]

does anyone know how i can differentiate what makes an Item food or water? I have this set up so far but not sure where to go from here

[crude iron]

You could use an enum

[teal talon]

Question: Can I clone a bone to another bone or in to another mesh?, so I could take the head clone and put it in the root hidden. Or in it's own skeleton?

[astral stratus]

@crude iron thank you I will look into that right now

[indigo bough]

Am I right in thinking you can't add blueprint components to variables? I wanted to make an array of static mesh components within the blueprint that I could then act upon, but that doesn't seem to be possible. Do I really have to drag out a reference to every component into the graph to interact with them?

[surreal peak]

You mean components that are part of your BP Actor?

You can just make an array variable, connect it to a make node and add the components once by hand. Call that in e.g. construction script or BeginPlay and you can use the Array from there on

[manic viper]

Ive got a physics object and im constantly reading the hit impulse on it. Most of the time it will do its initial run of physics and then stop generating hit events as its no longer moving. But every once in a while it'll stick on and keep generating hit events. Is there a way to stop that ?

[indigo bough]

Yeah that's right. Just trying to avoid doing that in the graph itself because I have hundreds of components to set up this way, and was hoping I could streamline it a bit 🤣

At the moment I've got a struct that carries the necessary information, and if it wasn't for the component reference issue it could all just live inside one variable 😦

No less work of course, just less clutter.

[tight schooner]

@indigo bough Get all components of class... Or some such node could also work if you don't care how the array is ordered

Get components with tag etc

Otherwise yeah gotta make array by hand at construction

[indigo bough]

Seriously thinking about tags, but yeah that's also not fun 😄 Okay, no problem thanks!

[dull tree]

I neeed help!!!! i accidentally deleted my MAIN BP, i cant get i back

what can i do?

[indigo bough]

Do you have source control set up?

[balmy apex]

Does anyone happen to know how I can use blueprints to get the player's spawn location to move a certain amount on the X axis each time they press a button that restarts the level?

[dull tree]

nope :(\

[indigo bough]

As far as I know, I think your only hope is to check the recycling bin, but I don't think stuff goes there at all

[dull tree]

😦

[indigo bough]

Everyone has to learn this lesson at some point 😄 It's a horrible thing to learn, but you need to set up some form of source control, or do regular backups

[dull tree]

yeah :/

[junior hedge]

Ue5 has an automatic backup

Check for backup in the folder of your project

I forgot exactly where it is (I'm not home)

It saved me, my entire level was deleted somehow

Simply pulled the level out of backup and was good to go

And the contents if you need them like I did

[manic knot]

Can anyone show me what Im doing wrong here??? Damage is only being applied to Client 1 no matter what I try. Running as Client

[faint pasture]

Start with thinking about what's even providing that spawn location to begin with.

How does your game mode decide where to spawn a pawn at? If you haven't done much changing, it probably just uses a player start actor right?

[balmy apex]

It's the character Blueprint Class

[dawn gazelle]

Can you show how you are calling the Apply Point Damage Server event?

Also, should be posted in #multiplayer

[faint pasture]

Yeah don't do that. The spawn location has to be stored somewhere that will survive the character being destroyed.

Why are you not using player start actors?

[balmy apex]

I'm not entirely sure honestly. Not sure how they work either

[dull tree]

i got it 😄

[manic knot]

Im calling it from a Function Set on a Timer at BeginPlay

[manic knot]

This is at the end of the Function that is on the Timer

[junior hedge]

alr

[manic knot]

I am getting the Target with a Trace like this:

[balmy apex]

Well, I've added a player start actor, but I'm still clueless about what I do now

[faint pasture]

Have you messed with the game mode at all or is it pretty much stock?

[dawn gazelle]

In this image it shows that you've marked the event as an "Executes on All" / Multicast function which you cannot call from clients.
Normally you don't want to let a client tell the server that they've hit something as it opens the doors for cheating. The server should already be running the hit detection itself, and then it determines the values and replicates what happens to other clients. If you had an exposed RPC like this, you'd effectively allow those with know-how basically kill everyone anytime.

[balmy apex]

All I have in that Blueprint is this stuff

[dawn gazelle]

At most, you'd want the client to signify that they've started attacking, and maybe a target.

[manic knot]

It was set to Server. I only tried Multicast to see if it changed anything

[faint pasture]

And does that work? If they die do they respawn at the player start actor?

Make sure to remove anything having to do with setting the character position on spawn from your character

[manic knot]

Ok the Client sets a Boolean when they are attacking. The Timer function only executes a trace when the Boolean is true

[dawn gazelle]

But that's not what the server would see. The server can only know what the client is doing if you use a "Run On Server" event.

[balmy apex]

No, they respawn where the Character class is

[dawn gazelle]

Example:
Client presses attack button > "Attack" Run On Server Event

Server sets a boolean true indicating the player is attacking (which you can then later reuse to prevent multiple activations), and the server runs the line trace. The server then determines who to deal damage to and uses the "Apply Damage" node.

Client releases attack button > "StopAttack" Run On Server Event

Server sets the boolean to false and stops the timer.

[manic knot]

Client is setting Bool via Server

[dawn gazelle]

Nope that's not good either. That's the client telling the server to set the boolean to what the client thinks the value should be. The server should determine what the value should be.

Eg.
If I was malicious, I could send a packet that spoofs that RPC at any time, and constantly set it true whenever I want to.

[manic knot]

This is in an Anim Notify

[balmy apex]

I don't think there is anything dictating that besides where I placed the character.

[manic knot]

So how then? I am setting the Trace as Server now, and it still applies damage only to Client1. Same as before

[dawn gazelle]

That looks better.

[manic knot]

How would I set the bool correctly in an Anim Notify? I mean, the trace and everything is happening, its just always damaging only Client 1

[dawn gazelle]

Perhaps your line trace isn't correct?

[junior hedge]

your branch isn't connected

dk if intentional or not

[faint pasture]

So you have a character on the map in the editor then right?

[limber parcel]

is there like a beta branch for UE 5.1 ?

i need the navmesh fix

[balmy apex]

Correct

I have a Character and now a PlayerStart both on screen

[manic knot]

Yeah I’m bypassing the branch

[faint pasture]

Delete the character instance from the level, and make sure that your character class is set in the GameMode

I'm saying delete it from the level

Don't delete the CLASS, just covering my ass here

[balmy apex]

I gotchu, but where in the GameMode do I set it

[devout geyser]

@faint pasture covering your ass? you wont get a lawsuit lol XD

[mint magnet]

I am trying to use a spline inside a blueprint in sequencer but it doesn't keep the amount of points I create. Anyone run into this?
