blueprint

[lost hemlock]

Do you think the problem is in that function?>

[dawn gazelle]

Check your inputs first in the GetText0 function.

Also these conversion from soft to hard refs you're using aren't good to use...

[warped juniper]

Thank you for the in depth explanation. I'm currently using Ints for the values given a strict design choice but it should be convertible to floats in UI for interpolation purposes...
I appreciate the thorough insight on this very much!

[lost hemlock]

Im putting a break point here but this get text 0 is never getting called

[dawn gazelle]

Put the breakpoint on the next node within the function

If it doesn't break there, then you haven't set up the binding on the text to call GetText0.

[lost hemlock]

okay, but im still getting nothing

[lost hemlock]

Im now having a break point on the second node in the fuction

[trim matrix]

dumb question. but i have a game idea where the player has two screens (vertical but was also thinking possibly some horizontal) and can travel from one screen to the other for things like, digging under an obstacle or enemy, falling down a hole in the top screen and being stuck in a new area thats on the bottom screen, etc. kinda thinking like how ds/3ds games are layed out ig is a way i could describe it, is there a way i could do something like that in unreal? (image just for layout reference)

[dawn gazelle]

In 5.5.1 when I breakpoint on a node within a widget binding, it forces my view to where that breakpoint is when I run the game, but it doesn't show the big red arrow.

[lost hemlock]

Mine is 5.4.4, but why are the breakpoints not working?

[dawn gazelle]

Gettin same behavior in 5.4.1, so it's something on your end.... Maybe try restarting the engine? Re-set the bind?

[warped juniper]

Question about performance / organization
I have a system where enemies have 3 body parts each with a Condition (CON) value
Attacks target 1 or more conditions.
To deal damage to them, I'm trying to access the according variable for that part (Ideally also supporting some form of damage modification to be added later down the line)

What would be better:
A) Single switch at the start that changes the Set nodes based on what is getting damaged
B) A system with Select nodes that pick variables based on Enum

[dawn gazelle]

At a fundamental level, selects are better for performance as it's a "non-branching" style of logic but I'm not sure how well that applies from blueprint logic. In reality, the difference between blueprint branching and selects would be absolutely negligible in the grand scheme of things unless you have literally thousands of these things running the logic every frame.

In terms of organization, if the logic required for each of them is all similar but just what variables are being manipulated are different, then selects are usually the way to go since they can produce less node clutter overall, but also have the slight disadvantage that it can make the logic slightly harder to follow, especially by those who don't work with selects all that often. If you end up having lots of select nodes as things vary between what is being selected for, that then can make it very confusing.

[lost hemlock]

Still, doesnt work

[warped juniper]

Got it. I'm not sure if there's a way to change the Set with something other than a switch at the very end... Or is there a select variable to set node workaround?

[dawn gazelle]

Set by-ref

You'd end up selecting the variable to use based on the enum, and plug the output into the set by-ref target.

[dawn gazelle]

Are you actually clicking Play or are you simulating, or..?

[warped juniper]

Thank you very much!

[lost hemlock]

clicking Play

But I can scrap the tick-binding all together and make it something more efficient

Something like this

[warped juniper]

Alright I revamped the code and it works better, looks better. Thanks!

[lost hemlock]

https://tenor.com/view/modern-problems-solutions-dave-chapelle-gif-13450651

[dawn gazelle]

Sure.... Ideally you'd use an.... Event dispatcher... Which your UI can bind to and you call when your inventory changes... Then your UI can just update itself when it receives the message. But for now... This will do so you can at least troubleshoot your problem if the binding isn't working for whatever reason.

[lost hemlock]

But now it's all blue @dawn gazelle and it's all unchanged like 3/5, blue color indicating that something is affordable, and 3/5 indicating no change on the binding. Also Im still not getting it called... even tho i have breakpoints

https://tenor.com/view/star-wars-obi-wan-kenobi-thats-not-how-it-works-thats-not-how-this-works-that-is-not-how-that-works-gif-25837746

[dawn gazelle]

With the game running, look for this drop down near the play button when you have the widget event graph open....

[lost hemlock]

oh wait, im also never using the binding

I mean the newly exposed variable

[dawn gazelle]

If you click on it, can you select an instance?

[lost hemlock]

New

[lost hemlock]

click on what?

Still... No change, and no break-point call either.

The numbers stay unchanged

so in conclusion I've taken out of the tick-binding function that block of code, and i've put it on the construct of my widget and have it connected to a recurring timer that connects to a custom event that finally connects to this block of code in purple and then at the end of everything I've connected this logic at the end to set the text because now im trying to use an exposed variable rather than a widget tick-bind

[dawn gazelle]

When running the game... Click on the Drop Down near the top where the play buttons are.

Select the first instance.

[dawn gazelle]

This means you don't have any of these on the screen

[lost hemlock]

I do have it on the screen

[dawn gazelle]

I don't see any.

[lost hemlock]

oh you mean the ingredients list

[dawn gazelle]

It's this side you're conerned about, right?

[lost hemlock]

But I dont see anything, they seem idle

[dawn gazelle]

Click on the C7 instance.

[lost hemlock]

those white cables are supposed to visualize the transmition of electricity

[dawn gazelle]

Wait. It should break point on it.

[lost hemlock]

Im on it rn

No change

[dawn gazelle]

put a print string immediately after the timer event.

right here

check in the output log for the name of the widget where the log is coming from.

[meager spade]

Did you create your own set tool tip text function or are you calling the default one?

Target is Widget makes me think what you are really doing is setting the text that will appear when you hover the border/widget, no?

[lost hemlock]

No this should update automatically every single second (almost)

[lost hemlock]

thats a good idea

[meager spade]

Sure, but aren't you setting the wrong thing here?

[lost hemlock]

It's not printing anything

[lost hemlock]

what do you mean?

[dawn gazelle]

You're setting the tooltip text, not the text box text.

[lost hemlock]

Even if it's setting the wrong thing, it still doesn't work

in the first place

the events dont work at all

[dawn gazelle]

We don't know that.

Just some odd behavior is happening.

[meager spade]

Can you show the widget hierarchy of the Widget that has "Wood 3/5"

[meager spade]

Instead of calling Set Tooltip Text Call Set Text(Text)

Also, I have no idea if this will help or not, but save the return value from the timer. Not sure if blueprint will prevent it or not by not saving the handle but I would consider it good practice

[lost hemlock]

no change

[meager spade]

Then it's the event not firing, but it's the correct function I can assure you that

[lost hemlock]

Earlier I was doing something like this, so instead of an event, it was a function, it would have the ability to change stuff within the 3/5 number here, but we would not be able to have Unreal Engine force my view to where that breakpoint is when I run the game. And that was crucial because I needed that to debug why the numbers weren't working properly

[dawn gazelle]

Out of curiosity... if you go to here... and change the class.... Do you have two different WB_IngredientSlots classes?

[lost hemlock]

I just changed it, I guess I'll also refresh this node now because i got all these input errors

Everything went on panic red alert mode as soon as I did that

I guess I'll just refresh the node

[lost hemlock]

This is how it looks like now.

so now it created more of the same ingredients clone widget or smth

[dawn gazelle]

The real question is whether or not you have more than one WB_IngredientsSlot classes.

[lost hemlock]

By default it's Slot

i changed it to WB_IngredientsView

[dawn gazelle]

When you click the drop down, do you see more than 1 WB_IngredientsSlot in the list?

[lost hemlock]

Yes

oh wait

you mean WB_IngredientsSlot ?

[lost hemlock]

no

[dawn gazelle]

The only thing I can chalk it up to is corrupted blueprint. There's no reason why you shouldn't be hitting the breakpoint in there, nor is there any reason why the print string isn't printing from the timer.

[lost hemlock]

Damn it🥲

[lost hemlock]

Should I remake just this blueprint?

anyway at least now we know it's something to do with that blueprint 👍

[dawn gazelle]

Why not try simpler first... Create a very simple blueprint that has a timer in it that prints... add it to viewport somewhere... Test it out... See if you can get a breakpoint to fire in it.

Maybe even try adding a WB_IngredientsSlotWidget on its own somewhere?

Feed in some random data.. see what happens

[autumn pulsar]

In a singleplayer game, what's the way to get the current player?

and the class of the pawn?

[dawn gazelle]

Current player what? PlayerState? Character? Controller?
Do you really need to get the class of the pawn?

[autumn pulsar]

I'm trying to get data off the actor component off of my player character

[dawn gazelle]

What kind of blueprint are you trying to pull this data from?

Like a widget?

[autumn pulsar]

yeah

[dawn gazelle]

Get Owning Player Pawn > Get Component By Class > Select the class > You can now access the contents of that component.

[autumn pulsar]

https://i.imgur.com/zL7EyFV.png

[autumn pulsar]

awesome thanks

What's usually the best way to sanitize an overlap event so I only grab the player character?

[frosty heron]

The player character class or specific player character?

There could be more than 1 player character in the world depending on the game.

[autumn pulsar]

it's singleplayer so just the player character class

[frosty heron]

I will go with casting

Player character will always be loaded anyway

[dawn gazelle]

Can always do Other Actor == Get Player Character 0 if you don't want the hard ref too.

[autumn pulsar]

well I'd hope it's loaded if it's generating an overlap event

[frosty heron]

If you want to always grab the character the player possess, you can do what datura says. Get player character 0

[autumn pulsar]

yeah I'd prefer to do it that way since I plan to make a few versions of the player character

[dull crest]

total noob question, what's the correct way to have a blueprint thats just a basic class?

I want to define a data type that TLDR stores a float, but also features a bunch of helpful functions for converting other forms of data to a float.

Basically what I'm trying to achieve, is have a centralized place to transform between various definitions of rotations to.. what I can best describe as "screen space", i.e. imagine an origin at the center of your monitor, with the "0 degree" definition going upwards vertically from it, with positive angles going clockwise.

This has been elusive since my main use case for this involves deriving this angle from mouse movements, but by default (atan'ing the delta of the mouse) defines the zero-degree axis as going horizontally left from the center of the screen

[autumn pulsar]

Actor Component

[dull crest]

i assume this is schizophrenically hard to interpret. What i'm trying to achieve is basically like

class AttackAngle {
  
  public float angle
  
  public AttackAngle FromMouseInput(float deltaX, float deltaA) { 
    ....
  }

  public AttackAngle FromControllerInput( ...) { ... }
}

[dull crest]

I see that this still brings with it a bunch of stuff regarding lifecycle etc, is there truly no way to get basically a struct that has functions?

[autumn pulsar]

it lives and dies with the actor afaik

[dull crest]

is this just how UE handles garbage collection? I'm not super familiar with C++ yet

[autumn pulsar]

I think if you want something persistent you'll need to make a manager actor

[dawn gazelle]

I'd think the functions themselves would probably be best suited in a function library if you intend to just be able to use these functions anywhere, and then you can feed them whatever float value.

[dull crest]

hmmmm I might be approaching this wrong to begin with tbh; thanks for answering, I think you've given me the "right" answer

[autumn pulsar]

Oh yeah there's function library

don't think it stores variables though

[dawn gazelle]

They don't.

[autumn pulsar]

You can make structs with datatables

err

[dull crest]

Maybe this is a wiser approach. I'm just somewhat wary of using singletons/static helpers over objects due to it bloating the namespace but thats probably an unreasonable concern in this case

[autumn pulsar]

structure class

[dull crest]

I think maybe you're right and I should just add util functions and store the actual data I need with primitive floats

for context the problem I'm dealing with is that I'm finding myself "handling" the differnet axis definitions in many places and am certain im gonna end up repeating myself

[autumn pulsar]

function library sounds like what you want

[dull crest]

like it's already making maintenance a headache, I'm trying to experiment with changing how I define the initial "angle" being dealt with and its cascading and busting a whole bunch of other stuff

forgive me for being vague btw i am kind of sick with covid atm and im struggling to communicate

i appreciate your help a lot guys

[autumn pulsar]

no worries

[dull crest]

(all of this is made way harder by me not having version control btw 🙃)

still havent quite figured out how to set up p4 without building an onprem server or pay for cloud hosting xd

(nevermind how much p4 itself costs, absolutely struggling to find that info)

but thats off topic

[autumn pulsar]

Version control? what's that?

[dull crest]

fun fact I left Roblox dev for Unity because i couldnt work without version control anymore

then Unity did the thing so now im a UE dev

and now i dont have version control again

[autumn pulsar]

I've never actually worked in a proper version controlled environment

Data hosting is so expensive

I ought to version control locally

Wrapping my head around doing doors

[dull crest]

ive only ever used git, genuinely life changing stuff

its so good

[autumn pulsar]

I think I'm overcomplicating it

[dull crest]

doors?

[autumn pulsar]

I'm trying to make a door base

but when you try to open one, a door can do many different things

slide up, slide to the side, etc

[dull crest]

oh literal doors LOL

[autumn pulsar]

yeah lol

I guess I'd be better off with an interface

[dull crest]

intuitively I'd say you actually just need a base class right

[autumn pulsar]

A wall is just a door that doesn't realize it yet

Was thinking maybe a door container BP that has the visual door BP

[dull crest]

Door -> SlidingDoor, SwingingDoor, VerticalDoor

class Door {
  
  bool currentlyOpen

  default void toggle() { }
}

etc

[autumn pulsar]

C# is so ugly lol

public static void

[dull crest]

yes

c#

😬

[autumn pulsar]

even worse

C++ is a dumpster fire as well

[dull crest]

i think theres multiple ways to slice the door onion, personally I'd probably give it state ("open?") meaning i'd use a base class

rather than an interface

btw for extra thoroughness I WOULD give it an interface for player interaction though

[autumn pulsar]

Well, I have a button

and it could open a door

or trigger something else

so I want to use an interface for that

[dull crest]

I_PlayerClickable

that has a function onClick or something

that then is overriden on the doors such that it routes to the door's open() method orwhatever, y'feel me?

[autumn pulsar]

yeah that was my plan to have an interaction interface

[dull crest]

sound plan as far as I can tell 🙂

what are you struggling with? were you venting or did you want my 2cents?

[autumn pulsar]

feels weird to have an interface for one thing though

[dull crest]

one function does not mean one implementation 😉

ive been doing professional SwEng for a bit now and I can tell you that the more things an anything does the more i hate it

personal take tho

[autumn pulsar]

Mostly just trying to figure out a sane way to do this

I think the simplest would be a double BP

one to handle the IO and then the other for the visuals

[dull crest]

dont forget theres more than just visuals

they kind of have a state

open or closed

and that im guessing has physics implications for your scenario

[autumn pulsar]

well my doors are planned to be kind of cinematic open and closing

[dull crest]

i cant say that i remember the last time i programmed a door though so grain of salt etc

[autumn pulsar]

physical doors

[dull crest]

do blueprints support multiple inheritance?

googlable question my bad

[autumn pulsar]

you can put BP inside BP

but my main goal is to let the door do its thing, then I can just cast any interactions to its parent

[dull crest]

you've lost me here

i suspect at this point im making the situation worse rather than better

[autumn pulsar]

I've lost myself too don't worry

I'll eventually figure this out

[maiden wadi]

If you want an okay source control, you can always use Azure DevOps, along with GitDesktop. Free and fairly easy to use, reliable source control.

[lost hemlock]

So I duplicated the same thing, and somehow now this works, ( not the function though )

[maiden wadi]

And no. Nothing in Unreal does really. Interfaces sort of are, but you can't put variables in an interface.

[lost hemlock]

I think it would be more efficient if all the updates were being done inside of the same Update event that resides in the main menu as well.

[dawn gazelle]

So yea.. Some kind of corruption or something then.... At least now you have some breakpoints you can use... Check the inputs on there during the breakpoint and see what those values are.

[lost hemlock]

Like a centralized update system, rather than tick-bindings

[lost hemlock]

Im thinking about this

[dull crest]

Does git play well with UE? Seems everyone uses P4, isn't the reason for it something to do with large files/binarization in a way that Git LFS cant handle?

[dawn gazelle]

Fix your current problems first.

[maiden wadi]

I use the setup I recommended for my personal projects outside of work. I've never had issues with it so far. 🤷‍♂️

[lost hemlock]

I think there still might be something wrong with the update though, it looks like after I destruct the menu widget, thats when the break points start to wake up. Maybe Im wrong

The Item Amount Needed seems correct

[dawn gazelle]

What about the inputs

[copper chasm]

I feel like I am overlooking something very simple: When my gamelog prints an entry to my UI, I have a text block that will capture a timestamp in a datetime structure. But as I print more entries, the time on ALL of them updates to the time on the most recent one

[dawn gazelle]

Ok so right now your WB_IngredientsSlot widgets are showing 0/#, right?

[copper chasm]

I got it, don't turn the ints to a string use a datetime function

[lost hemlock]

yes exactly, it works somethign like this, the name displays the name from the thing which you pick up

numerator/denominator <-------- Only the **denominator **changes, but the denominator shouldn't change

It's actually the opposite, and I did all this by following everything the person in the tutorial did, and still came out wrong, so it looks like it should be the opposite, **denominator **should be fixed, and **numerator **should be affected every time you pick up something.

[dawn gazelle]

That' not what your problem is right now.

Your function isn't returning values.

the inputs were important to check because we needed to make sure you were passing legitimate values to it.

I wanted to verify what you're seeing... You should see 0/<whatever value is required for the craft>

which should change at least once from the original value of 3/5 (the default text you had in the field

SO.. the problem lies in your inventory system.
So now you need to check how items are are searched for in your inventory, and that items are properly being added to your inventory.

[lost hemlock]

It seems like this function node is also called down here

So this function has a branch which seems more like an airport security, but this security lets all the data pass anyways no matter what happens

(This is from my InventorySystem Component blueprint)

[dawn gazelle]

So the very first item doesn't match, it'll return anyway.

disconnect the false execution to the return node and run it again.

[lost hemlock]

So they are all "Names" now

but why is this not changed?

All my items names are literally names of type name

where's before here I was using string type. Comparing it to Name Item ID..

So now on this function im comparing Name to Name

[rugged junco]

new on here and have been doing reworks on my project. how do i notify when the character hits the ground once they finish a jump? i want it so the character cannot dodge in mid-air and i've been trying to use gameplay tags to do this, but can't seem to have it so it removes the tag after the character lands. any advice?

[autumn pulsar]

types are weird like that

[lost hemlock]

oh wait I think it's a different struct

[dawn gazelle]

Text values are supposed to be something that is localizable. So when you have text you want displayed, that's when you use Text as if you ever want to release your game in different languages you'll be able to easily replace the text with a localized version.

Names are effectively "named values" - in the background names are stored as numbers but are human readable otherwise - this is part of the reason why it doesn't convert from text.

[lost hemlock]

should i change everything to text instead?

or everything into string

[pulsar osprey]

names very efficient to pass around! you can explicitly convert them to text iirc

[dawn gazelle]

Of course, you're not prevented from doing some monstrosity conversions, but those end up costing more in the background to do...

And no, you don't want to just convert all to one or the other.... You want to use the appropriate type for what it is you're trying to do.

Name = Good for IDs for things.
Text = Good for displayed text that can appear in UI and the like.

For an item definition, you'd want to probably use both. One as the means to identify, the other as the displayed text whenever you need to display it to the user.

[maiden wadi]

Converting Names directly to Text. 🤢

Localization is such a brutal thing to learn.

[dawn gazelle]

If you're using the character class, you can add this event

[autumn pulsar]

Finally got my doors working in a sane manner, so proud https://cdn.discordapp.com/attachments/755254770301665290/1319526011599065199/UnrealEditor_zmuTnrbT8H.mp4?ex=676647dc&is=6764f65c&hm=2114aec43bad79cbb4d9b89f06ee389a87706a68e4811b8c84118e78f5701bb7&

[lost hemlock]

This works !

Kinda

[dawn gazelle]

Bytes | Type

16 | FString
12 | FName
24 | FText

[lost hemlock]

It seems like it's aware of when it should let me craft and when not, but seems now only the number display is the last missing piece of the puzzle

[lost hemlock]

Is there a difference?

[nova grotto]

is there a way to constrain a springarm to a plane?

[dawn gazelle]

Yea it's all to do with how they're stored.
FName is smallest because it's not really storing the name as a string itself... it's storing a value associated to the name.
String has to store a series of characters. I'm 99% sure it can actually go beyond that 16 bytes for how long the string actually is.
FText is set up to store a table and ID so that it can locate the appropriate text to be used with the particular field. It doesn't normally directly store any text.

[rugged junco]

thank you so much! exactly what i was looking for!

[lost hemlock]

I found out that by connecting these, I no longer have the color indication of when I can afford to make something

but now by connecting this cable, you get back the number indications

they are working fine, only thing is they are in reverse

*So now you're getting no color indication, it always stays red, and the numbers get passed on the *denominator

numerator/denominator <----

denominator should be fixed at /1, numerator can be any number over zero.

[dawn gazelle]

Are you sure about that.... Usually it'd be indicating current amount in inventory / amount needed for craft

[gentle urchin]

I never realized this was the crafting menu

Thought it was an inventory lol

[lost hemlock]

yes but I feel like they could be stored into the wrong variables, so they could be reversed somehow right now. But then the other problem remains that zero is never getting away. That would be explained if HasItem? was always false, but thats not the case.

[dawn gazelle]

That's a pretty big assumption. Look at what the flow says and that will tell you where the problem is.

I'll give you a hint. It has something to do with this variable.

[lost hemlock]

Earlier I tried to pass the Quantity straight to the >= but that didn't get me very far either

[dawn gazelle]

That's definitely part of it.

But why is it part of it?

[lost hemlock]

because it should be connected

thats passing the values directly

to the ingredients calculator system

from the inventory

[dawn gazelle]

You're running the IsItemInInventory function which returns true if the inventory has the item, and also the quantity of those items in the inventory but you don't have the quantity hooked up anywhere.
Right now, what value is being passed into the text display?

[lost hemlock]

Oh wait I think I know why, maybe its because I didnt have this connected earlier. Maybe

[dawn gazelle]

Ahhh!

There you go 😄

[lost hemlock]

But it still looks reversed

wtf

[dawn gazelle]

It's not reversed. Your branch there doesn't look right.

You're checking if Quantity in Inventory >= Item Amount Needed.

[lost hemlock]

This comes from here

[dawn gazelle]

You're only proceeding with the logic if this is false.

You want to proceed with the logic if it is true...

[gentle urchin]

The branch would mostly be a color selector, and first false disables craft button?

[lost hemlock]

So perhaps this branch would be crossing it's legs there?

But it still doesn't work

no change noticed

[gentle urchin]

Theres also a ton of data being pushed all over the place

[dawn gazelle]

That's because that's not what I was saying at all.

[lost hemlock]

the 2nd branch?>

[dawn gazelle]

See this one here/

It's only executing if false.

You want this one executing when true.

[lost hemlock]

I did try that one as well.

[gentle urchin]

You want it on both, dont you?

[dawn gazelle]

Not "as well". Only.

[gentle urchin]

True = has quantity

Or am i looking at the wrong branch?

Yes i am

[gentle urchin]

Ignore me

[dawn gazelle]

You know you have the item in the inventory.
Therefore, you want to know whether or not you have >= to the required number of items in your inventory, and IF TRUE set the colors and use the appropriate formatting for the text.

[lost hemlock]

yes but its not working

[dawn gazelle]

Let's see what you have for your screenshot currently.

Sorry for my confused wording.... I've been fighting a headcold since early morning yesteray.

[dawn gazelle]

So now back to breakpoints. There's probably something wrong in your inventory that it's not returning the correct numbers.

[gentle urchin]

(Dont think the last branch is necessary really.. quantity should return 0 if item wasn't found ...)

[dawn gazelle]

ALSO... Going to suggest this... Disconnect the completed pin from this return node. Add a second return node and leave it all disconnected except fro the execution path from completed to it.

[gentle urchin]

You also shouldnt be using the same return node

Always use explicit return nodes when using fast tracked returns

[lost hemlock]

I dont have a function

Im using an event

[dawn gazelle]

I'm talking about in the IsItemInInventory function.

[lost hemlock]

oh you're right

[dawn gazelle]

That won't fix the problem, but it's makign sure you're not returning values that shouldn't be returned.

[lost hemlock]

Empty?

[dawn gazelle]

Yea, connect the completed pin to that empty one.

[gentle urchin]

Is items unique in inventory?

If not, this function is wrong

[lost hemlock]

not always unique

[dawn gazelle]

Well, right now he's not even registering any items at all, let's see if we can at least get him a number to be displayed.

Hit play, gather some rock or wood or whatever... bring up your crfting window where it's displaying the items needed to craft, then put a breakpoint on the for each loop in that funciton. You should then be able to inspect the contents of your array there.

[autumn pulsar]

Is it possible to tag triangles in collision?

to make special collision cases

[dawn gazelle]

No they are not.

[lost hemlock]

But I see them being added

every time I open the crafting menu

[dawn gazelle]

You have 5 wood in your inventory but it displays 1 on there.

you have 4 rock, but it displays 3 there.

[lost hemlock]

Thats a different play run-time

[dawn gazelle]

Well part of the problem is this.... Why is your inventory saying item amount needed based on the contents of the iventory?

How is this even updating... I don't know.

[gentle urchin]

😆

[lost hemlock]

https://youtu.be/utiJIU35ow8?list=PLrudBLqLfaTQHKmoVmSDqq0__GMYlJpxP

[gentle urchin]

Amount required should come from the recipe

[lost hemlock]

He shows the result of each video at the start, at first on the first few seconds of the video he gives an explanation for what its gonna be about

[gentle urchin]

Current Quantity -> is requested from Inventory

Required Quantity -> is requested from crafting recipe

[lost hemlock]

Im trying to fix this part where the names and numbers and color indication is displayed properly, no need to worry about the update

because the update will get taken care of in the next parts

on part 9 he says is where he guides through the update

but I can't move on with the update if I first dont fix the other more basic stuff

[dawn gazelle]

But the numbers and color indication won't work correclty if you're not getting the values right.

You're doing this bit on construct, that means it'll set that value one time.

But then you're saying you're seeing it increment the "Item Amount Needed" each time you pick something up....

HOW can it being doing that if you don't have logic changing it somewhere else?

[gentle urchin]

There is only one answer to this riddle

[dawn gazelle]

Do you still have a bind set up on that text field?

Are you setting that value somewhere else?

[lost hemlock]

no

actually i do have a bind on it

but it doesnt work, right?

[dawn gazelle]

If you ahve a bind set up , the bind would end up taking precedent since it executes every frame.

[lost hemlock]

im setting it, but am I incrementing it? Incrementing would Imply that Im using a ++ node before the connection to that SET

[dawn gazelle]

I didn't say you were incrementing it somewhere... just that you're seeing it increment.

[lost hemlock]

true

[lost hemlock]

are you asking how am i Incrementing this?

or where am I incrementing?

[gentle urchin]

Lol

This is the correct function to use

Im confused why you have the other one at this point

Especially since it returns what looks like quantity. But its really "QuantityInFirstFoundSlot"

[dawn gazelle]

Where are you setting this variable in the WB_IngredientsSlot2 blueprint

other than on the construct of the widget

God my spelling is so bad right now too @_@

[lost hemlock]

Here

oh wait thats not a set

[dawn gazelle]

OH... You're deconstructing the widget entirely?

[rich coral]

why im only can get the state weight (cover walk left)? but i have cover walk right or idle too

[lost hemlock]

Im never setting it

only once

[gentle urchin]

This sets the exposed variables. You dont need to update itemAmountNeeded on construct

Remove that chain of logic

[dawn gazelle]

concerned

[lost hemlock]

This is no longer in use though

[lost hemlock]

This chain? I get that I gotta remove the last SET, but the whole chain? ⛓️ ⛓️‍💥

[gentle urchin]

The last two nodes are bs

[dawn gazelle]

Yea you don't need these

Then replace this function with "Get Item Amount From Inventory"

Remove the first branch. The second branch true goes to top, false goes to bottom.

Then it should work.

[gentle urchin]

Wellll

maybe

I share your concern, to put it thah way lol

[lost hemlock]

This is almost fixing it

But right now I've picked up more than 4 rocks and some wood

but no response

[gentle urchin]

It disturbs me that you use hand typed identifiers for items

When gameplaytags exists

A silly typo would break this setup

[dawn gazelle]

And I'm wondeinrg if that's happening because you're using conversions for the name field

[lost hemlock]

ok I think you're right, I could use actor has tag to make a comparison and then work with them that way? @gentle urchin

[dawn gazelle]

GameplayTags != actor tags

[gentle urchin]

^ sad truth

Very very sad

[lost hemlock]

I already had problems earlier when I tried to change "Rock" name to "Stone" and the color indicator thing didnt work on the rock but everything else

[frosty heron]

Comparing hard coded characters in 2024

[jaunty jolt]

Can anyone explain me why the random changes twice ?

[frosty heron]

The moment you need to rename it you will have to go through dozens of bp as well

[frosty heron]

It will be evaluated per white pin

If you want to use the same result, cache it

(Promote to variable)

[jaunty jolt]

so each white pin it executes all the code before????

[gentle urchin]

Pure nodes connected to it.

[frosty heron]

You might want to read about pure nodes

[jaunty jolt]

though i cant do that because im in a Collapsed Node

[gentle urchin]

Undo the collapsed node

Make a function instead

[frosty heron]

That's got nothing to do with how pure node works

[jaunty jolt]

ok will do that

[gentle urchin]

It was for the cachimg part with local vars

Collapsed are still just regular event graph, so no local variables

[jaunty jolt]

so collapse nodes have this flaw

[frosty heron]

Oh yeah, local variable would be a available for function

But you will lose the ability to do latent action

Pros and cons I guess

[gentle urchin]

I never ever do collapsed 😆

[jaunty jolt]

its great

[gentle urchin]

If i need it latent, i use macros

If not, i use functions

[frosty heron]

I did in earlier days, now I don't do anymore logic in bp

Only prototype stuff

That bp corruption experience terrifies me

[gentle urchin]

Gotta burry the axe with it

[frosty heron]

But only happend because I did cpp stuff I guess

[gentle urchin]

Stay safe with backups

[frosty heron]

Never had problem when I did bp only

[gentle urchin]

Coming from the guy with 0 backups

I have to much faith

[jaunty jolt]

macros also dont allow local variables?

[frosty heron]

Back up doesn't help when it break silently

🥹

[gentle urchin]

They do but they're different

[gentle urchin]

Stay alert ! 😆

[frosty heron]

No source control 👀👀

Nooo way

[gentle urchin]

Nada...

[frosty heron]

I can't believe it 🥹you out of all people

[gentle urchin]

Only 1 of my 4 active projects got source control

[frosty heron]

I see

[gentle urchin]

Which ofc is bad

Stupid as hell

Its what happens if you drive your car 2 million miles and you never have a flat tire

[frosty heron]

Stepping on a minefield is a wakeup call

[gentle urchin]

You start trusting it

Untill it rips the floor from beneath you

[frosty heron]

Yup, until the day it break 🤣

[jaunty jolt]

sorry to interrupt you guys. but how does a macro get local variables

[gentle urchin]

Right click in the graph

Local integer/float or smth

Afaik locals in relation to macros isnt really locals

They're just hidden member variables

[jaunty jolt]

so only function will work in this situation

[gentle urchin]

No, it will work for a random node

Also

In 5.X they added an option to convert pure nodes to unpure ones if im not mistaken

[jaunty jolt]

this seems to be what you are referring to

[gentle urchin]

Set by ref

Yes

[jaunty jolt]

amazing

though there is no Local Name

unfortunately

[gentle urchin]

Thats prob true 😕

Prob local string tho

If you really wanted to..

But

Youd save the local index

Not the name

And get the name from the name array with the index

[jaunty jolt]

ahh i can just use the integer of the first array

[gentle urchin]

Peeersonally, unless latent, id put this in a function instead

Macros are like.

Code templates.. when you use it you 'paste' the code template into the code where you use it, resulting in more code to compile and execute

Compared to a function which only exists in one place in memory, is compiled once, and is reused every single call

[jaunty jolt]

okay thanks

[gentle urchin]

Only caveat being functions are required to return instantly, and thus cant be latent / delayed in any way

[jaunty jolt]

though this set by ref var is amazing

[gentle urchin]

Its usefull for maany things

That along with a select node can be pretty powerful in terms of code cleanliness and readability 😄

Also GameplayTags are worth getting used to. Predefined hieriarchal list of tags with a bunch of utility functions and typo safety !

[jaunty jolt]

im on it 💪

[jaunty jolt]

it seems these are like some sort of global bools

[frosty heron]

Global bools? That would be material collection param but global is pretty bad in general.

Nothing to do with gameplay tag though. Gameplay tag is basically FName on steroid.

[lost hemlock]

Yes but it's already converted

Oh wait

This is my struct

[frosty heron]

Why is the rarity a byte 🫠

Also hard reference in data table is bad.

You will end up loading all the icon/image on the entire DT.

[gentle urchin]

I use them for IDs of almost anything

Stats, quests, npcs, scene cameras, you name it, i got a tag for it

[lost hemlock]

All I did was to change this one, and everything is broken

I'll put it back 👍

[untold fossil]

Hello. Is there a way to find out how much seconds have passed using the time nodes? I want to include a timestamp into a spawned actor and then I want to later check the actor's timestamp against the "Now" node to find out how many seconds have passed. How would I do this?

Would this work?

[gentle urchin]

On spawn -> save now to a variable

Yepp

I thiiiinkn

It returns the full thingn

So youd need to combine everything bigger than and including seconds

[untold fossil]

ah right

but wait

[gentle urchin]

Unless theres a seconds node avalible

Directly from timespan

[untold fossil]

how about this?

[gentle urchin]

Yepp

[untold fossil]

👍

Will test if this works, thanks

yup it works perfectly

noice

[tiny tundra]

is there a way to check if an actor doesn't have any tags?

[normal raft]

array length

[tiny tundra]

yeah just figured it out. if length == 0. But thank you

[frosty heron]

Is empty()

[gentle urchin]

10 ways to skin a cat plushie lol

[kind estuary]

I have a function in one Widget called Deliver Medicine.
So when i click on a button in my widget it delivers medicine.
But then i need this function also in another widget and in a character.
So i just copy pasted it in 3 places.

Obviously this is not a good practice

What should i do here. BlueprintFunctionLibrary sounds too much and not necessary

[frosty heron]

the issue is why the function lives in the widget to begin with

widget just read and display info, the sooner you accept this workflow the less stress you will have.

[kind estuary]

because its called from the widget

https://tenor.com/view/idiocracy-electrolytes-idiot-gif-5371704

[gentle urchin]

pastamaker will make pasta

[frosty heron]

called from the widget doesn't mean deliver machine need to live in widget...

get a ref to an actor that is actually RESPONSIBLE for delivering the machine

Widget->GetTheDeliveryMan->DeliverMachine

stressing this again
#blueprint message

[kind estuary]

okay so i put it in the character and then cast it then deliver medicine

[frosty heron]

well does it make sense for the player to deliver the machine?

really depend on the context

[kind estuary]

can also create uobject

ah

[frosty heron]

or just an actor manager

[kind estuary]

uobject, create uobject, MedicalStuff->Deliver

[frosty heron]

again, depending on the goal....

[dark drum]

Adding to what Cold said, doing it this way, you'll also find you wont need to repeat functions in different BP's any where near as much. It helps keep things more consistent and less prone to bugs. (Granted you'll still have plenty of bugs lol)

[frosty heron]

like if you have a BP that can edit rooms and have functions like deleting walls or adding props.
Then widget just go ButtonClicked->BP_RoomManager->DoIt'sThing

@gentle urchin I'm gonna try to attack the dot product today

#blueprint message

[kind estuary]

yeah just need to pass reference to the blueprint of my Character. which is a bit annoying

[gentle urchin]

you got this champ!

Meanwhile im doing stupid shit with my cameramanager

inflicting pain and suffering on my pc

[frosty heron]

no pain no gain

[dark drum]

Does anyone know what I'm doing wrong? The cursor is on the stump but the trace hits the ground to the right. (The cursor doesn't show when I do a screen grab lol)

I thought I might need the position scaled by DPI but it gives the same result.

[gentle urchin]

can't you just get hit result under cursor?

does all this crap for you

[dark drum]

Making the window smaller makes it worse. (cursor still on the stump)

[gentle urchin]

they're always so sneaky

GetHitResultAtScreenPosition is what they use in c++ 😄

not bp exposed, ofcourse

who'd ever need such a thing

internally they seem to be what you're doing in the end

        return GetWorld()->LineTraceSingleByObjectType(HitResult, WorldOrigin, WorldOrigin + WorldDirection * HitResultTraceDistance, ObjParam, FCollisionQueryParams(SCENE_QUERY_STAT(ClickableTrace)

[frosty heron]

just went thru the function, it looked like it does exactly the same thing

[gentle urchin]

only differencei can see is mouse position

if (LocalPlayer->ViewportClient->GetMousePosition(MousePosition))

[dark drum]

I find it funny how we all went and looked at the player controller class. 😅

[dark drum]

Yea, that's what I noticed. I'd love to know what the difference is with what i've done.

[gentle urchin]

//BP node:
FVector2D MousePosition = FSlateApplication::Get().GetCursorPos();
FGeometry ViewportGeometry = GetViewportWidgetGeometry(WorldContextObject);
return ViewportGeometry.AbsoluteToLocal(MousePosition);

// cpp :
FIntPoint MousePos;
Viewport->GetMousePos(MousePos);
if (MousePos.X >= 0 && MousePos.Y >= 0)
{
    MousePosition = FVector2D(MousePos);
    bGotMousePosition = true;
}

so BP gets it through slate

while cpp gets it from viewport

which uses some CachedGeometry

[dark drum]

Using the wrong 'Get Mouse Position' node it seems haha. You know because there's 3 of them. o.O

[gentle urchin]

Haha yeah

let's givie them options lol

[frosty heron]

does it work now?

[dark drum]

Yea lol.

[dark drum]

They do like to throw some red herrings in there. 😅

[gentle urchin]

keep it spicy 😄

[dark drum]

Pick you're poison.

[kind estuary]

i realized why i didnt do it that way before. its because this is part of a dialog system. So you are talking and then there is an option in the Widget to Give Medicine. And others like Bye, and others. So this is why its in the widget

Because after you Give Medicine, there's a new dialog message, and this is called from the widget

Cant be called from the character

[frosty heron]

there is no reason for any gameplay to be in the widget. Only logic widget should contain is the logic to display the info. E.g, go to next page, etc.

If it's part of the dialogue system, then make the function in the dialogue manager.

then Get the dialogue manager and call it to do it's thing

[dark drum]

Event dispatchers are great for things like this. It can allow for the UI to do things without it ever knowing about the thing it's caused.

[dark drum]

If it helps. If you add an event dispatcher to a widget, it's like giving it a specific sounding bell. Then you can tell things to listen for that specific sound. When the widget rings the bell, anything listening to it can choose to do something.

[kind estuary]

i think i will pass the widget itself into the function in my character, and that way i can deliver medicine and then keep going with dialogue after

[frosty heron]

no comment without knowing the architecture

[wide beacon]

Hello, im creating a point and click adventure game for my uni project, im struggling finding a way to create a simple inventory system that stores the items, so when i interact with a pedestal at the end it takes those items and completes the game. i was wondering if anyone could guide me in the right direction when it comes to using blueprints like this. thanks!

[thick flame]

Hey! hoping to get some advice here. Im trying to make it so the player can "push off of" surfaces in a zero gravity environment. It mostly works at the moment, but sometimes the player will just start moving in a circle rapidly. Is there a way to make the movement only a straight line?

[dark drum]

I tend to include initialization functions with delegate inputs for event dispatchers. When you create the widget, you can call the initialize function and decide what event should trigger when it's called.

[dark drum]

Are you wanting to be able to view said items? drop them or anything like that?

[thick flame]

have you looked into Data tables? thats how ive seen them handled. You can have the data structure contain all the important info for each item, and all your game systems can reference the table or the structure

[lost hemlock]

Does anyone know what this is?

[wide beacon]

so the idea is to collect 3 artefacts and have them seen on the screen as you keep exploring to find them. once you have all 3 in inventory you return to the pedestal that sent you to find these, then ypu click it an it places all 3 on there and takes from inventory.

its not meant to be complex but im just so new to all of this

[thick flame]

to iterate- afaik it would be best to have two data tables, one that contains all the items in the game, and then one that is the players current items. The second one would point to the first for information about each item

[wide beacon]

which finishes the game

[dark drum]

I'd go down the uObject route. Pt 1 - 3 in this series. You can probably ignore the other parts. Part 4 might be useful as it shows you have to display the data in the inventory.

https://www.youtube.com/playlist?list=PLcwVLBaUNnHoujbPwOAdMgNtq1ShoHIGc

[wide beacon]

okay thank you very much!

[dark drum]

That's assuming you actually want to learn how to make an inventory system. With what you've described, you could probally just get away with an array on the player character using gameplay tags.

[wide beacon]

yeah im not trying to create an advanced system, my lecturers said keep it simple due to the time frame, how would i go about this array? i think its to create more of a trick as the inventory wont ever be accesible its just there to display what you have.

[frosty heron]

Can I see your data table?

Data Assets are prefered majority of the time.

[thick flame]

I havent actually made one 😅 not for an inventory system, ive just seen it in videos

[frosty heron]

the pitfall with data table for most new comers is they use hard reference on their DT

and they end up loading the items in the entire game when they just need to display a few

[thick flame]

last DT i used was for a camera position table

[frosty heron]

Youtube videos are notoriously a bad trap for such important system

[dark drum]

Actually, just follow pt 1 - 3 lol. I've just thought you'll need to have the other data such as icon images and possibly the mesh to display and other things. It should only take you about 90 mins to watch the first 3 parts. 🙂

[thick flame]

ive found its very hard to get any information on unreal, tbh

[frosty heron]

written articles are normally a great source of info

youtubers tend to copy other youtubers

wrong information passed around

[thick flame]

it sucks that the official documentation is so outdated

[frosty heron]

we have victims saying oh don't use cast use interface on daily basis

@gentle urchin sorry to bother you, what would be the range for the dot limit?

[thick flame]

ive heard that too- ive been trying to get away from casting, bc like a lot of beginners i used it for everything. I just saw interfaces but havent used them

[frosty heron]

You shouldn't get away from casting though... You can stay away from interface, you can live without them.

@thick flame https://dev.epicgames.com/community/learning/tutorials/l3E0/myth-busting-best-practices-in-unreal-engine
If you are looking for a well documented info about common myths prepetuated by bad actors.

[dark drum]

Casting is fine as long as you're using good hierarchy. Over using interfaces can be problematic and make managing systems difficult in the long run.

[thick flame]

when i need to cast, ill cast. but ive seen other people in uni or myself in older projects casting with every action

[thick flame]

good to know

[thick flame]

gonna take this, ty

[dark drum]

Function only base classes that you then create children of is the way to go in my opinion. Casting to these types of base classes are pretty much free as they would most likely already be loaded.

[gentle urchin]

whatever you want it to be

-0.7 was suggested

goes from -1 to 1, in full range

[frosty heron]

sorry I mean, the value does it range from -1 to 1

ahh yeah, thanks

[thick flame]

bumping this

[dark drum]

How do you know this is making the character rotate?

[thick flame]

This is the only code within the first person character i've created. It didnt do this until this point. I had flying working with normal wasd controls

[dark drum]

It might be worth trying to add velocity instead of impulse. As a guess, I would say the impulse (if not being applied perfectly central) would impart some rotation movement.

[thick flame]

so that didnt help, but it definitely seems to have to do with collision. At certain angles, the player will start spinning around a central axis faster and faster, even without any input.

it could be that the when I look around, im clipping the characters hitbox into the ground? its a first person game so its a little hard to tell

[lost hemlock]

How is it possible that the top part is 5 and the bottom part is 1 and this is FALSE?

[dark drum]

From the screenshot it looks like it hasn't evaluated the >= node yet. You need to step ahead so it's calculated.

[normal raft]

how would implement this

not sure how to create a new BP_WEP_OBJ..

[dark drum]

What are you trying to do?

[normal raft]

create a array of weapons from a structure

[dark drum]

For what purpose? We require more context.

[normal raft]

First so i can define custom weapons in the graph

then so the player can switch between them in the game

[tropic token]

you don't need this set members. you aready created it with Make node

[thick flame]

very strange- it seems to be almost random angles that the character starts to shake or rotate around a point. not sure how to even go about fixing this

[dark drum]

It sounds like you should be using data assets or at the very least a data table. The weapon obj would most likely need to be a soft class ref so the relevant class can be spawned at runtime when needed.

[gentle urchin]

Let me know when it works lol 😄

[normal raft]

ok let me check into those two concepts

[frosty heron]

I'm trying to add a slider to an actor component atm, skill issue is on the way

[dark drum]

Slide to an actor component? Sounds interesting.

[frosty heron]

https://www.youtube.com/watch?v=ovpiYkYFlPM&ab_channel=UnrealEngine

just more editor utility stuff

[gentle urchin]

Ohh fancy that

I just left it as an input field

You can specify min max values there

[frosty heron]

yea I should probably just leave it as input field

[gentle urchin]

And it has built in slider

[frosty heron]

I don't know why I am even trying with this , pretty sure I don't even know how to save the value.

[dark drum]

Yea it's pretty cool stuff. I wish there was a way to make custom BP graphs and nodes without having to jump into C++. That stuff is wild haha.

[frosty heron]

There's some degree of support with editor utility blueprint I think

[normal raft]

ah and yep all it needed was "Add BP Weapon Component" noded to make it logical

[frosty heron]

kinda questionable

not that I have done my own weapon system

you probably want to create the UObject when you initialize an item from a data asset

[gentle urchin]

just dive into c++ and get custom nodes 😄

[dark drum]

It feels more like falling from the top of a tree and hitting every branch on the way down to make custom event graphs and nodes lol.

[normal raft]

yeah lol i had a little tour of that recently just slap functions in the h file and get nodes like @gentle urchin says

[gentle urchin]

just keep it simple in the start 😄

it's pretty awesome once they work

[dark drum]

I can imagine.

[thick flame]

it starts out so well....

[frosty heron]

got it working but I am really wasting my time doing something I don't need

[clever comet]

Is there a way to fix an actors capsule component inplace during a root motion animation? 🤔 So that essentially the root moves but the capsule doesn't

[pallid dagger]

What it does? I guess first vector is forward of owner, who is the second?

I don't have any logic yet, Squize is helping me out with the logic

[gentle urchin]

[frosty heron]

i'm trying to filter out targets that is behind my characters

[pallid dagger]

and how it goes?

[frosty heron]

[gentle urchin]

only because you're doing editor extension

instead of just doing the code 🥲

[pallid dagger]

https://tenor.com/view/red-panda-pumpkin-play-attack-fall-gif-3517702

always distracted

[thick flame]

heres a video of whats happening. I already tried selecting true on velocity, thats the same outcome.

[frosty heron]

not sure what the goal there

you want the player to bounce when colliding?

[gentle urchin]

Dont get distracted ! Stay focused !

[frosty heron]

brb 2 hours

[gentle urchin]

Its not a perpetual motion machine you're making 😅🤔

[thick flame]

the player bounces, and they can also push off the wall by clicking. but theres some spasming happening randomly and im not sure why

[manic orchid]

Hi chads! Just wanted to make a quick line trace function that checks if certain Interface is implemented onto an object.

My Idea was to pass interface reference as input parameter of the function, but this doesn't seem to work... Why is that? What type do I have to choose for it to be compatible?

[lost hemlock]

Why does this number always remain stuck?

[frosty heron]

Why are they in different order?

[gentle urchin]

But whyyyy u do this in cpp 😂

[frosty heron]

I'm using the same function..

[gentle urchin]

You couldve asked and i couldve sent you the snippet 😂

Im using it for my custom world space screen space widgets 🤣

Oh well wheres the fun in not making it yourself !

[frosty heron]

@gentle urchin having the visual... I kinda understand it more....

so one arrow that goes from -1 to 1 (clock wise)
and another arrow that goes from -1 to 1 (ccw)

[gentle urchin]

Yepp

meanwhile trying to implement my first pathfinding algo

wanna avoid copy pasting from the interwebs

so i truly have to grasp the fundamentals 😄

[frosty heron]

I never touched EQS in my life

is that something that you will need?

[gentle urchin]

not using EQS

I already have an array of my tiles (its a grid based game)

so it should be fairly simple to implement pathfinding really

[frosty heron]

@gentle urchin ty for the codes, I might have to ask you about tiles next time 😅 . I would need to use that for dungeon generation

[gentle urchin]

Im using DA for that

[gentle urchin]

Nice !

I got some easing aswell

Priority / Soon Irrelevant / No Priority

So basically 2 dot values to check for using it as an alpha for widget opacity

[maiden wadi]

EQS is fun. Wrote a bunch of that lately for AI.

[vagrant remnant]

trace ✅
differenciating wall and floor ✅
setting cube's position to impact location ✅
rotating it along the impact rotation thingy ❌

how can I get the needed rotation for my cube without making my brain explode of hard math?

[gentle urchin]

Oh yeah i bet, its just one of those things i havnt gotten to yet 😂

[maiden wadi]

They're surprisingly easy to write. Funny enough the logic they need is harder than the test code. Pathfinding ones get a little iffy, but like basic target selections and stuff are a breeze.

[maiden wadi]

Unsure what you're after?

[copper chasm]

Physics, I think? 😅

[vagrant remnant]

rotating the Red cube to make it fit to the trace impact normal

I am just playing around with the engine since I'm a newbie 😅 there needs to be a lot of fixing for this

[copper chasm]

I went alllllllll the way back to start to try and include replication for the gamestate and include a logging system I can use in game and for debug, might revisit your suggestions for grid generation - might actually make some headway

[maiden wadi]

You mean so that the cube will fit up against the wall correctly?

[vagrant remnant]

yep

currently I'm tracking the Location and the Normal of the trace hit

[maiden wadi]

Should be all you need, mostly. Just need to set the cube's world rotation to the Normal converted to a rotator.

[vagrant remnant]

sounds like it makes sense

what is the trace's normal btw?

is it the normal of the face it Hit?

I'm not on my pc currently

[maiden wadi]

Yeah. If you want something more normalized on a messy wall you would need to do more traces after the initial to establish more points to normalize against, but for an initial implementation the original normal should work.

[vagrant remnant]

nah this is just for fun and even if it was a game I would make extra hitboxes for it

[vagrant remnant]

for a messy wall some sort of "slime" that adapts to the geometry would look better though
New project idea :)

[frosty heron]

@vagrant remnant https://www.youtube.com/watch?v=A_3mvosV_oU
You will have a tough competition

[vagrant remnant]

that is so cool :O

[austere vapor]

Hi all! I'm working on a rail shooter where you travel through an endless maze, with each room containing enemy spawns, traps, etc. What would be the best way to go about creating a map that can fetch and spawn/insert these pre-made levels? Some of these rooms are themed, so I want to be able to select from a few at a time. I've seen a lot of different stuff like level instancing, level streaming, world partitioning, packed level blueprints, theres a lot! And I dont know which would be best for me! Obviously not looking for any grand tutorials, but which method sounds best for what I want?

[maiden wadi]

Initially sounds like a case for level instancing. Your main map would just be blank mostly and then you'd have logic somewhere that manages streaming in a level. When done with it you stream that level out and then put a new one in.

[normal raft]

hey .. i managed to get it working ... if any ones curious.. I just dont like that is not explicity a "new" instance the way that looks to me but let me know 😄

[maiden heath]

Hi everyone, a question in Unreal is it possible to modify the Physics of the "Skeletal mesh" in runtime?

[normal raft]

i think that comes under ragdoll physics stuff

[maiden heath]

Example if I enlarge only the hands of my Unreal mannequin how do I change the size from the standard to the ones I modified

[normal raft]

not sure i fully understand what you want to do but do you want to transform the bones perhaps?

I saw some stuff in the graph nodes about that comming of the SkeletelMeshActor

[maiden heath]

I would like to make a test that if I enlarge the hands or lengthen the arms of my metahuman the physics changes along with the modification

[normal raft]

yeh theres a bunch of physics stuff on skeletelmeshactor also

[civic halo]

I spent 2 hours creating a Dynamic Material because I'm trying to change the color of a mesh to tell it's attacking.

I have the Material but I don't know how to get the changing part

I have a Boolean (bIsAttacking) so I'm trying to sent a Event tick Branch = True but I'm not sure where to go from there

[maiden heath]

Ok where can I find to make sure to change physics in Runtime

[normal raft]

to get the nodes i am talking about

[muted socket]

Sorry I just started today with blueprints so bear with me.
I have a LP player in my scene and I added two buttons in world space on top of it, one for "play/pause" and one for "skip song".
I made an actor for the button and in there I have a variable to distinguish between them.
I want the player to be able to walk up to it, when he's close the buttons show up, and when he looks at one of the buttons and clicks the corresponding action gets triggered. To do this I trace a line every Tick out from the player camera, check if it's intersecting with the button, if it is get the button name, check which button it is and then either play the song or skip the song. It's working properly now but it just looks convoluted, so I was wondering if there's a more straight forward approach to this.

I guess what I'm asking is: is this normal for such a simple scenario?

[normal raft]

thats not too bad is it 😄

[muted socket]

I don't know, that's why I'm asking, since I'm learning on my own I want to get on the right path from the get go

[normal raft]

no i dont think so some of these graphs get kind of insanely large 😄

[muted socket]

ok thanks 🙂

[normal raft]

I swear unreal needs to allow us to zoom out more then -12

like i fear having to do endless if statement in graph i would absolutely be running the visual studio hills at that point

but the good thing about that in theory is you can just make the first condition in graph then go find that bit of code and implement in a c++ function node

[normal raft]

sounds like a job for event overlap / hit

[civic halo]

I have this here for Dynamic mesh

and im trying to create something like this to change the color

Butim not 100% sure how to do so

bIsAttacking comes from this

[north bobcat]

does anyone know how to make quake and halflife movement like air strafing and surfing in ue5 blueprints?

[maiden wadi]

You can remove most of this code and just change your update function. Then you just need to change the boolean and call the update function.

[dark drum]

Does anyone know why this would be triggering before I've released the button? My understand of the released trigger could be wrong.

[crude helm]

Any ideas on why I can't draw a rect on tick on this hud class? Sample I'm folowing is drawing a rect on tick of the hud class. Don't quite get why mine says it can't draw outisde DrawHUD event...

even if I have fixed values..

[maiden wadi]

The warnings at the bottom will tell you.

[copper chasm]

From what I understand, released causes it to fire started and ongoing when you press, and then it’ll be ongoing for every tick it’s held down, then it’ll be triggered when it’s released

Without seeing the inputaction node or the code, idk what it’s actually doing vs what you want it to do, but I’ve had my ass chapped by connecting started and triggered and making assumptions about how things SHOULD work 😅

[charred cobalt]

hey does anyone know if there's a way to get the max walk speed to not apply while in the air (I am very new)

[normal raft]

perhaps look at a gravity system

[dark drum]

Thanks for the explanation. I know what I've done wrong now lol.

[crude helm]

that doesn't help.
Even using the Event **ReceiveDrawHUD **it still spam the same warning

[dark drum]

You can change air control on the movement component.

[dark drum]

There's an event you override I believe.

[crude helm]

as far as I understand, this is the event that need to be used
Event receiveDrawHUD
It draws, but also spam gazilhon warnings

[maiden wadi]

It shouldn't. But Mouse buttons can be finnicky too given viewport capture and such. Try it with a keyboard key to see if it stops firing too soon.

[normal raft]

see this is why i dont get ue sometimes.. why is this being made so stupid! ... it so obvious and fairly trivial what i am trying to do... but it refuses to work .. as soon as you attempt to optimize any thing

[vagrant remnant]

thanks @maiden wadi <3

[dark drum]

It's ok, I was using started instead of triggered. 🤦

[dark drum]

Ahh, sorry, I was thinking of the one inside widgets.

[muted socket]

I'm trying to cycle through a list of sounds. It works except for a small detail, when I first click on the "next" button I have to click twice to reach the second song, after that it cycles perfectly. I'm guessing that it's because it plays the sound first and only then it changes the current sound index. How do I fix it?

[maiden wadi]

If you play the sound automatically, the starting index should be 1 instead of 0.

[muted socket]

I don't, the player has to move up to it and hit "play". Plus I'm not sure why it should be 1 in that case? It's still playing the first song in the array, right? But it does work if I set it to 1, I just want to understand why

[dapper fern]

I might be too burnt out to see it and I need help, it's a simple combo logic but I can't manage to go past the first anim montage I'm supposed to play

[maiden wadi]

When you click play. Do you set CurrentSound to 1?

[muted socket]

Wait no I see it

[maiden wadi]

Because your logic right now is Play. Which probably plays track 0. Then you cilck next. Which plays DefaultValue, and then adds 1 to that default value. If DefaultValue is 0. Then your next button causes it to play 0 on the first click before adding 1 to it.

[muted socket]

these two should be swapped in order

and it works

thanks

[maiden wadi]

Also an option

[muted socket]

it makes sense, first you change the index, then you play the sound

[maiden wadi]

InstancedPerActor or InstancedPerExecution?

[dapper fern]

The master is instanced per Actor but the child is instanced per execution (The parent being the Ability that holds the logic and the child, the one that holds the montages to play)

Ah fuck, thanks dude

[maiden wadi]

Parent setting doesn't matter. The child is setting it to per execution. Which means that it's a new instance every time. 😄

[dapper fern]

It was indeed the problem

[maiden wadi]

🥳 Glad it works.

[olive yarrow]

*big fan of the physics, less a fan of the player physics.

How do i stop the ragdolls from freaking out the player while still interacting with the player?

[maiden wadi]

What causes the player to jump and turn like that?

Is that an onhit/overlap in the player's BP?

[dawn gazelle]

In case 1, where "IsItemInInventory" returns true, you're using the value "ItemAmount" in your append. If you don't manpulate this variable anywhere then it's going to use its default value of 0.
In case 2, where "IsItemInInventory" returns false, you're declaring 0 as the value in your append, so therefore it'll display 0.

[vagrant remnant]

do blueprints not support hierarchy? 😭

[lofty rapids]

maybe give the thing some weight ?

[olive yarrow]

I'll give it a go! thanks

[dawn gazelle]

They do... I can create BP_Vehicle and make a child class of BP_Car of it. BP_Car will have all the same properties and functions of BP_Vehicle.

[vagrant remnant]

nono I dont mean inheritance

I wanted to check if the actor I hit with my trace was inside the SimulatedCubes Folder

[lofty rapids]

i would just make a tag probably or just make them all child of some parent

[vagrant remnant]

they are the child of the folder though

and I don't want to apply the tag to each cube manually

can I make cpp functions inside my blueprint?

[maiden wadi]

Folders are an editor construct for organization. They don't really exist at runtime gameplay.

[vagrant remnant]

oh

[lofty rapids]

ya you can run cpp and make a blueprint function library where you can nuse it anywhere in your game, but can you check for getpathname node ?

you can probably parse that

[vagrant remnant]

Authaer said that it won't exist in-game anyways so

are tags the only solution for this?

[pulsar osprey]

you can call c++ UFUNCTIONs in BP, but you can't define a c++ function in blueprint

[zealous moth]

you can also just use parent-child and test for the parent

[pulsar osprey]

that seems like a bad idea

[vagrant remnant]

why? 😭

[pulsar osprey]

that folder is just getting filled with different cubes that have nothing in common with each other

[vagrant remnant]

yea, so?

[zealous moth]

I missed a bit, what do you have in that folder?

[pulsar osprey]

if you want similar behavior between them, make a baseclass, or use tags (which also aren't great)

also, that folder will no longer exist when you make a standalone build afaik

[vagrant remnant]

first person preset, just the cubes (StaticMeshComponents I think)

[zealous moth]

I'd go for a tag and if you have further interactions a BPI

[vagrant remnant]

I just want to get if the actor my trace hit is one of those cubes

[pulsar osprey]

then use a tag

[zealous moth]

or a parent

[pulsar osprey]

^

[vagrant remnant]

seems stupid for a project of larger scale

[pulsar osprey]

what

[vagrant remnant]

what do you mean by that?

[zealous moth]

reparent your cube actors to a common actor

[pulsar osprey]

having functionality based on filepath is maybe the least scalable option

[vagrant remnant]

that's what we did in roblox studio so I thought it worked the same here

[vagrant remnant]

what should this actor be?

[vagrant remnant]

like this?

[zealous moth]

create new actor of class actor, then name it something like BP_Cube_Parent and then in your cubes, reparent them to BP_Cube_Parent.
Then, in your trace hit, check if the actor is of class BP_Cube_Parent either as a cast or boolean

wait what

show whole hierarchy?

[zealous moth]

huh... ok, you meant in the level editor, i thought you meant in the general directory

then tags

you can select them all and add the tag

[normal raft]

man why does the undo history also have to be such a lag fest

[vagrant remnant]

big data

[vagrant remnant]

component tag or Tags under the advanced section?

[zealous moth]

i did a test on this, i think it's actor tags

you can try both and see which ones work

[vagrant remnant]

okay I see now how this works

yay it works

thank you :)

[lofty rapids]

i like the parent class approach it has other benefits but tags also works

usually if your children all have something in common you can make a parent

[olive yarrow]

made that sumbitch heavier but physics assets still make the player start breakdancing. preciate the advice regardless!

[north bobcat]

does anyone know how to make air strafing and bhopping in ue5 blueprints? dm me plz

[regal frigate]

you need Jumping Mechanic , true ?

maybe this will do the trick

[rigid bay]

I want to set up a character that can run and walk, depending on whether the alt key is pressed, or whether the movement stick is in a certain range. I already figured out how to do it, but the way I did it is pretty complicated, and doesn't work with the wasd keys. Is there a simple way to set that up?

[wide beacon]

does anyone here have any idea how i can reference this key to this door so it unlocks it? ive been trying for a while and have gotten no where.

[ruby cobalt]

hello. simple question.. just not used to do this kind of stuff in BP.

I want to modify a string.. discard any characters to the right of "_r"

solved, thank you

[dawn gazelle]

If the goal is to have the door be flagged as unlocked when you interact with the key, you're close if you're intending to set which door the key unlocks within the level editor on the key itself.
You'd have to implement the Pick Up Key interface in your BP_Door and that can set an "unlocked" bool to true which you can then plug into your branch.

[wide beacon]

thats exactly what im going for, i have an inventory system and im trying to make them work together.

[wide beacon]

i have it implemented, however i dont really understand how to set it as an unlocked bool.

[obtuse gale]

Hello, I'm trying to make a game, where player can throw grappling hooks at different objects and interact with them: move them around, switch levers, pull down ladders etc. I have several actors that share the same parent class and I'd like to specify a point/component where my hook should attach to upon collision. I was thinking about adding a mesh/component variable to the parent class, and select it manually for every type of actor, but I can't can't set it's value, since the list is always empty, even though actor has mesh components. Is there a way to reference a component in a class, or should i go for a different approach. I'm new to OOP, so sorry in advance xd

[velvet wigeon]

is there a way to rotate a 3rd person camera to a desired rotation within a single frame?
ive tried set control rotation, but it sets the camera's rotation the frame after, and ive tried attaching the point of rotation to a component and rotating that but the result is different from the camera's rotation when moving naturally

[regal frigate]

maybe it helps you

copy this go to unreal and click ctrl+v

that is door and key blueprint

[velvet wigeon]

nvm, ive found a workaround

[dawn gazelle]

You can't populate that variable with a default value as it's not something that can exist at editor time. Create a pure function in your parent class called "GetComponentToAttachTo". Override it in child classes and grab the component you want to attach to and plug it in to the return value. You can now call this function when needed on any of the child classes to get their desired component to attach to.

[dire vale]

I've looked everywhere and I'm sure it's something simple I'm overlooking. I can get screenshots once I'm back at the desk.

I've got a character that has a sash that is rigged. I've set up the skele for physics sim on those bones. Looks great in the physics asset simulation.

Added rigid body in the animation box right at the end before pose.

However the sash turns into a thin line but the constraints still look to be correct.

I'm thinking it's a scaling issue but I can't figure it out.

[faint pasture]

Why is pick up key an interface?

Start with the data

what does it mean to "have" a key?

WHO (which actor) has WHAT data

[obtuse gale]

Wow, thank You so much! I wouldn't have thought about that 😄 OOP is hard to get used to xD

[faint pasture]

That's a good fit for a component

you can make a custom component and have it do many jobs. The component is the thing that the hook is looking for, it's the thing you give an actor to give them hook interaction, and it can be the location/hitbox for the hook to hit

I'd subclass USphereComponent, you can do that in bp

you'll basically make a sphere collider with extra stuff (the hook grabbing bit)

[obtuse gale]

Would it be possible to parent this component to other component actor has? For example if I'd like to attach my hook to the "lever" part of the lever actor, that can be pulled, changing position of the attachment point?

[faint pasture]

yes it can do anything a sphere can, plus some (the bits you add)

you might want to consider what you subclass, you could subclass static mesh or whatever, depends on how you intend to do the pulling stuff

IDK if you're using physics or what

but this component can be how you add "hookness" to an actor, just plop the component on it, implement OnHooked (for what the actor does in response to being hooked), if needed, and voila, you're done

Just like how an HPComponent might be how you add Healthness to an actor, and Damagability

[wide beacon]

im not sure if this helps, im trying to make the door unlocked once the key has been picked up, could it be becasue im using an object and an actor?

[regal frigate]

To tell you the truth, I don't know much about blueprints, but I had such a code, so I thought I'd post it, maybe it would help.

[faint pasture]

What do you mean by "once it's been picked up"?

[obtuse gale]

yes it can do anything a sphere can,

[faint pasture]

does the act of picking up the key unlock the door, or is the door openable if you "have" the key?

is there only one key and door per level?

[wide beacon]

when the player presses lmb on the "key" it is destroyed and then should unlock that specific door. however it does not unlock the door.

[faint pasture]

That should be simple. Have a bool on the door actor BP that says if its locked or not, and have a Door actor reference on the key BP.

on pick up of key, tell door it is now openable

set the reference in the editor, basically telling a key in the world what door in the world it cares about.

KeyBP
DoorRef MyDoor //set this in the world editor
OnPickup -> MyDoor.Islocked = false

DoorBP
bool IsLocked = true
OnTryToOpen -> if !IsLocked -> Open

Done.

[wide beacon]

i really appreciate you writing that out, is there anyway you could visualise it for me, it helps me understand better.

[faint pasture]

start by making sure your door has a bool representing if its locked or not, and that your key has a door ref so it knows what door it cares about

1 variable each

[wide beacon]

?

[faint pasture]

you don't need 2

pick one and delete the other

[wide beacon]

okay

ive kept unlocked

[faint pasture]

sure

now make a variable of type YourDoor object reference in your key bp

[wide beacon]

ive got that already

[faint pasture]

@wide beacon

make it public so you can set it in the level editor

[wide beacon]

the door public?

or unlocked?

[faint pasture]

the door

so you can set what door a key cares about in the world editor

[wide beacon]

ive done that

[faint pasture]

k so show your current setup. Show the key bp, the door bp, how the character interacts with the key, and the fact that the key door ref is set on the key instance in the world

[wide beacon]

i think the problem is my key is an object type and my door is an actor, so i cant pick the door with key with that object if that makes sense?

does my key have to be an actor too or can it be an object?

[faint pasture]

why do you have a BP_Key object and BP_Key1 actor classes?

just do it all with actors for now

[wide beacon]

the actor was a test, i have other items. but if it isnt a problem ill use the actor version of the key and keep these other items on this separate thing.

[faint pasture]

you need to decide on what your system is

I wouldn't go straight into using UObjects if you haven't done a super simple actor based approach yet

what does it mean to have an item in your system?

[wide beacon]

youre so right, they are literally just there to be seen, as soon as you ollecet all items you place them down and this completes the game

im making a simple poiny and click adventure for a university prohect

[faint pasture]

why would they be UObjects then

you can't place a UObject down
