nice

im in debt with you

[lofty rapids]

no your fine lol

i help people all the time, its no big deal sometimes i just give the code

its easier then explaining

[spice cradle]

god bless your heart

[atomic solstice]

How do you sort object arrays (alphanumerically)? --or is my strategy just wrong?

Trying to load arenas that cycle through an array i.e. arenas 1,2,3,4:

• top image: Get All Actors of Class for level instances gives me a scrambled array (2,1,3,4. not 1,2,3,4)
• mid image: converted to a string array so I can use Sort String Array to sort it by display names (arena_1, arena_2, etc.)
• bot image: there's no Unload Level Instance (by Name) 😬

[maiden wadi]

You could map the instances using their name as a key. Pull from the map to unload them.

[atomic solstice]

perfect solution works now! thanks.

[normal furnace]

If I'm making a blueprint-only actor component, is there a way to override a function on the actor that owns that component from within the component blueprint?

[frosty heron]

You can fire a delegate instead which can call function on the actor level

[frosty heron]

@normal furnace here is example, you have a delegate in the actor component.
In any actor that has the component, you can select the component and fire a function when that delegate is called.
Any actor that listen to the delegate can fire their own respective function.

I think that's what you are after because owning a component can't magically override the owner method.

[hardy merlin]

Don't forget that you can add input variables, and I strongly recommend including a pointer to whoever broadcast the event for the first variable.

[frosty heron]

not sure if that's related

[maiden wadi]

You don't need that for components so much.

[frosty heron]

you already have the ref to the component anyway, you have access to it's properties

[maiden wadi]

Depends on the component. Some maybe if you're doing some generic component manager. But in this case you know what component broadcast too due to the way they bind in the actor.

[frosty heron]

@hardy merlin were you asking about how to manage camera the other day?

[hardy merlin]

Yes.

[normal furnace]

Thank you! Much appreciated.

[hardy merlin]

I speak from experience. If you're suddenly binding multiple things it becomes a problem tracking them. I just always include a source pointer as a baseline so I dont have to change the signature later.

[frosty heron]

I think ultimately if you want custom behavior you can just override the event in the camera manager. That will be what you are seeing.
Not into this deep my self, but I manage to yoink Lyra Camera.

The way they do it is they use gameplay tag to switch to different camera mode.

What ever the camera mode is, ultimately the UpdateView is what the camera sees. So you can override that and have any custom logic you want.

[hardy merlin]

Noted. I'll begin investigating.

[frosty heron]

this might not be related if you are asking for temporary control for cinematic or something like that but Lyra implementation to address clipping issues on the corner is an absolute life safer for me because I wouldn't be able to come up with the logic my self for a long time.

tldr: it works where spring arm doesn't.

[maiden wadi]

That reminds me. I need to check out that one sample project with PCG and the camera thing.

[hardy merlin]

Anyone know why I have a "-1.00" at the origin of my empty scene?

[maiden wadi]

O.o

[frosty heron]

👀

Nothing on the world outliner?

[hardy merlin]

Sounds like something a teammate might have done.

[frosty heron]

Editor stuff that draws on screen perhaps

[hardy merlin]

From within a widget, how can I get the player controller that owns the viewport of the widget?

[maiden wadi]

GetOwningPlayer

[hardy merlin]

Cool! The last thing I need is that when I click the Resume button I am hiding the menu but I also want to have the game view re-capture the mouse pointer. How can I do so?

[maiden wadi]

For like a shooter?

[hardy merlin]

Third Person template, yeah.

When I click Resume, the menu hides but the mouse is not captured so I have to click an extra time.

[maiden wadi]

Should work with a SetInputModeGameOnly usually.

[hardy merlin]

Ah, I see.

I'll have to work out how best to manage the different modes.

[maiden wadi]

CommonUI is usually a better way if you have the time to learn it and adapt to it. It's activatable widgets swap input modes for you.

[hardy merlin]

Is CommonUI official or a marketplace plugin?

[maiden wadi]

It's in engine

[edgy field]

is this some engine bug, or it's normal that setting collision profile to MyProfile turns it into Custom instead of MyProfile ?

help please

it happens sometimes, not all the time

which is why I'm asking

[edgy field]

bruh, channel is so dead

[opaque wagon]

or ur issue didnt happened with others.

[edgy field]

I mean, in that case people could reply : it's potentially an engine bug

[lofty rapids]

The change happens when you make a manual modification to any of the collision settings on a component, such as a static mesh, in the Details panel. Even if you've already assigned a named collision preset, any individual overrides will switch the displayed preset to "Custom"

this is what the googles says about it

It is completely normal behavior for a component's collision profile to change from a custom preset like "MyProfile" to "Custom"

[lofty rapids]

does it just switch to custom when you click on it immediately ?

like you click the profile and it auto switches to custom ?

[frosty heron]

That sounds like an A.I

By google do you mean gemini?

[lofty rapids]

yes it was just what came up with the google search

[frosty heron]

Treat A.I as guess at best

[lofty rapids]

yes i've known it to be unreliable

thats why i mentioned it was "google" not me saying this

[edgy field]

Yeah Apparently it was that #cpp message
Though, the weird thing is that the Print call is right after the SetCollisionProfile .. and it returns "Custom" often .. which is why it was not easy to guess the issue

So yeah its solved now

[maiden wadi]

I hate that the first thing that pops up on Google now is AI shit. It's never correct for me either.

[lofty rapids]

prompting ai is frustrating lol getting it to help with blueprint stuff is usually a real hassle

1000 prompts later i get something that works hopefully

[blissful grail]

I hate how every so often, Google will pop up with a modal asking you to try more AI things and you have to close it to get your Google result.

[boreal basin]

Wait

Tmrw I do want to improve on my Unreal Blueprinting skills, mainly with moving my current movement system from the Character Blueprint onto GAS + Build up said Character’s Player State/Player Controller.

[lunar sleet]

I like how they’re saving money by asking you if you want AI to get you a summary after the first few searches where it’s automatic

[junior robin]

how do i become as smart as you

[lunar sleet]

Perseverance

[junior robin]

no seriously

do you just grind unreal engine vidoes on yt or smth

[modern horizon]

i have a problem to where whenever i teleport my skeletal mesh somehwere and walk backwards, it starts spazzing out. and its done the same when i used a cable component instead of a skeletal mesh, i don't believe its something to do with my code (i can show it anyways but someone already said the codes fine), but i believe its something to do with something in the details panel.

[maiden wadi]

Watching a bunch of videos will give you a vague understanding of things. But you need to learn to learn. Dig in, make things, understand the numbers and concepts. Don't just watch.

[frosty heron]

not smart at all, takes a decade to just be where most people are in a year.

I don't even touch a lot of things I should have. Common UI and asset manager being one of them 😭

[edgy field]

probably do a lot of small 3 days game projects
and try things .. without being afraid of making mistakes

[frosty heron]

I did and there is a point where I unlearn a lot from what I see in youtube.

[modern horizon]

anyone know why?

[frosty heron]

the smart people don't really grind youtube tutorials. They have problem solving skill and read what they need to know.

[lofty rapids]

"something in the details panel" <-- you would hope this is the case, your using physics handle ? idk what sort of setting your using, but i think i saw the code the other day. You were setting a variable in multiple places and then now your not right ? and it only happens when you go backwards ?

it looks like it's fighting for position or your setting it's location more then once

[modern horizon]

it also happens when you go side to side

and i was only setting the variable twice yesterday, technically.

[lofty rapids]

also i would try #animation like i mentioned, just to valid your using the animation stuff coreectly

[modern horizon]

its not a animation because this exact thing happened with a cable componenet i used instead of skeletal mesh

[lofty rapids]

so your only setting it once now ?

[modern horizon]

no, the other part where i set it is for grabbing objects

[lofty rapids]

show the two spots where your setting it

[modern horizon]

and that doesn't even get executed until i grab something

[lofty rapids]

right but your grabbing the ground ?

[modern horizon]

yes

it still does this when i grab objects.

i thought it was something to do with camera lag, but apparently not?

[lofty rapids]

and if your holding something it doesn't do it right ? so did you try to set the target location to grab point when you grab the floor ?

[modern horizon]

yes

found something, even when im not grabbing a object. it still spazzes out in a subtle way

so it has to be somewhere outside of the event graph

[lofty rapids]

idk what you keep saying in the details panel, your saying physics handle component has a setting that fixes this ?

[modern horizon]

what is it?

[lofty rapids]

I'm fairly confident its something with your animation and the target points

especially if it does it without using the grab point variable

[modern horizon]

well it was happening with the cable component, so i don't really think so. but can you try explaining what you said about the physics handle?

cause that makes sense if its the physics handle messing something up.

[lofty rapids]

idk what your saying, i was asking you a question

[lofty rapids]

so show the way you set this its a bone transform on a boolean right ?

show where you set the boolean

[lofty rapids]

ok so one sets is grabbing, when is the other one running ?

[lofty rapids]

when do these run ?

[modern horizon]

the other one is when it cancels

first image is when it cancels

second is when it turns on

[lofty rapids]

wdym "when it cancels" ?

and wdym "when it turns on"

[modern horizon]

first image, grapple on = off. second image, grapple on = on.

first image, when you let go, second image, when you start grabbing

[lofty rapids]

at the end of tick on your character

print this boolean

is it is grabbing ? is it flip fopping ?

see if its working correctly

[modern horizon]

its always printing true

but that doesn't matter as that string will only print when i pick up a object

and my problem is outside of that

[lofty rapids]

geez

[modern horizon]

my problem is outside of animations

[lofty rapids]

ok...

[modern horizon]

as it spazzes out while it hasnt even moved or extended a bone

as seen here

[lofty rapids]

that proves nothing

it defiantely could be the animation

and your not checking like i would of hoped

obviously not at the end of a bool restricted thing

heres a better option

but the print string at the beginning of the tick

do that instead

and see what it says

[modern horizon]

ok

true when grabbing ground and object

false when not.

[lofty rapids]

do you see these warnings ?

i would fix that

looks like your collision doesn't have physics

this could definately be an issue

[modern horizon]

what does this mean

it takes me to the event tick

[lofty rapids]

accessed none

this means the value is empty

click on where it says print string

[modern horizon]

i already deleted the print string

so its all fixed probably

[lofty rapids]

wdym all fixed ?

you should show things in order

don't show old shit

[modern horizon]

im confused

i didnt show you anything old

[lofty rapids]

is it "already fixed" ? or its been throwing this error ?

[modern horizon]

don't know, i deleted the print string before sending that but didnt compile so who knows if thats a old error or not

but that error has nothing to do with the issue

[lofty rapids]

you should know

and yes it does

it breaks everything

it could be the problem

you keep saying its in the details panel

but i don't even know what that means

you have to fix your erros

and debug the problem

[modern horizon]

details panel

[lofty rapids]

you should know

[modern horizon]

theres most likely something here breaking it

[lofty rapids]

what in the world makes you think that ?

[modern horizon]

how am i supposed to debug this?

[modern horizon]

maybe because i said already that this happened with a cable componenet i used instead of a skeletal mesh, and the fact that it spazzes out even when im not grabbing anything

its not related to the event graph or animation.

its outside of those.

[lofty rapids]

ok, good luck

if you really think it's in the details panel just mess with all the settings

but it's probably not tbh

but you do whatever you think is right

[modern horizon]

then what is it,

[lofty rapids]

i'm just debugging

[lofty rapids]

could be many things, you have to debug, this is very common and how you fix problems

it's very rare that a problem happens and you just say, this is the solution

debug the thing

you have errors

fix those first

before you do anything

and the warnings

and you might see this will fix it, if it doesn't go to next thing

[lofty rapids]

the same way you debug anything, step by step make sure everything is working correctly

but just assuming its in the details panel is not a good way to do debug

lol but it could be a setting you might be correct, but you need to go down the list

[modern horizon]

its outside of the event graph still.

ive already said how it is,

[lofty rapids]

saying this is just not how to debug

you do you

tbh, i hope you figure it out

[onyx tapir]

engage is telling you to debug from the beginning, because even if the problem lies in the details panel or not you can come across many other issues or not from a full debug.
Prints and Breakpoints.

I'd start by solving the two warnings in your log. Both of those could most definitely cause the "spam" issue.
You never know, just try.

[modern horizon]

Ok, I fixed it in the details panel

Was a problem with tick settings 👍

[lofty rapids]

cool

glad its fixed

[thin acorn]

Is this the correct way to do this? It feels off...

[maiden wadi]

Right click GetChildComponents and at the bottom ShowExecPins

Other than that, Not sure. Maybe? Not many people use ChildActorComponents much anymore.

[lunar sleet]

Is CAC not borked anymore?

[thin acorn]

Is there a better way to cast the children to an object to call a function in them all?

[maiden wadi]

Not really.

[thin acorn]

Going with this, works fine enough

[lofty rapids]

cache the array

that node runs foreach one of the loop

because it's pure

[maiden wadi]

Pop out them exec pins!

[narrow sentinel]

is there a way where when one physics actor hits another the mass of them equates into whether the one being hits gets any impulse or anything from it

I bassically have a turret firing projectiles at astroids but I don't want it to be the projectile causes the astroid to get sent off

espically when the projectile wouldn't have that much power

[steady night]

Hey Anyone know how to use PS4/5 controllers D-pad as button inputs ive got the rest working but all tutorials jsut wanting to use the value inputs from it i just need them as buttoon inputs (Using Raw input IPlugin)

[potent bear]

Does anyone know how I can unbind from an event through blueprints?

[lunar sleet]

Same way you bind, just select the unbind

[potent bear]

but what node do I pass in as the event? Is there a node like the "Create Event" but just for retrieving an event?

[lunar sleet]

The create event node is just a shortcut so you don’t have to plug in the actual event node

[potent bear]

So this would unsubscribe it?

[lunar sleet]

Yep that should do it

[potent bear]

Got it

thanks

[stone field]

So if BP_WrongPlace has a function I want to move to BP_RightPlace. And that function has already spread around to dozens of places. Is there no way to cleanly move it without having to do a copy, and go through all the nodes and update them manually?

To anyone who has worked on this before: https://github.com/Narxim/Narxim-GAS-Example/tree/master

I'm thinking of applying my Movement Controlls to GAS, but I'm unsure where do I start + mainly on if its possible to do so. If it is, how would you guys do it for GAS?

Also I need help setitng up Player Controller/Player State(mainly for future plans, but I just wana set it up early for my Single-Player game first).

[digital glacier]

if we forget about the "preventing cheating" aspect, why shouldnt i have vitality levels like hunger/thrist be calculated on the client side

if youre thirsty enough, you slow down. if youre too hungry, you'll die, but this can all be handled on the client no?

i dont see a reason to have the server aware of these levels

is my reasoning correct?

[maiden wadi]

Server saves the game. Has no idea wtf Client's values were at savetime.

[digital glacier]

mm, youre right

but if we werent considering that as well, would it still be okay to run on client

just checking to see whether my understanding of "what things should be replicated" is correct

[maiden wadi]

It's also a general state management. Consider if you want to put a character in like a hunched over tired looking state when starving. For the server this is simple replication. For a client you'd have to be constantly telling server what the values are anyhow so that it can tell every other client.

In a nutshell. It just complicates things to not simply do it on the server and let clients be a peeking window into the "real" world.

[digital glacier]

ty

[hardy merlin]

I havent used Narxim but I am prettt comfortable with GAS.
The key thing would be creating attributes that would modify movement, and then overriding the Character Movement Component's various functions to use those attributes. For instance, I have move speed and turn speed multipliers as attributes.

[hardy merlin]

What kind of help do you need with player controllerm

[boreal basin]

Will share both my Character Movement and my Player Controller after my Japanese language classes, so mind me for the delay currently.

[hardy merlin]

Character Movement will require C++

[frosty heron]

for multiplayer, yes.

single player you can use blueprint to further degree for cmc

[proud bridge]

hi, is there a reason that this code is not working in a standalone game?

[atomic solstice]

Is there a reason why audio only plays after I release my movement keys (WASD)?
initially thought it was just firing play constantly so i never get to hear it but the audio should stop still when no movement?

[modern horizon]

Hey @lofty rapids (sorry for the ping, but i think you'd know this), im trying to teleport my cord to the object so i can grab it, but it goes to the center and not where i grab it (im trying to grab it at a corner/edge), and ive tried numerous combinations of follow camera +/x/\ grabbed component, and for some reason i cant figure out how to do this basic stuff.

[lunar sleet]

Well for one you’re looking for an exact match to a float

Floats can be like 0.00000000000089 . So it may never reach actual 0.0. Try near equal instead with a low margin of error

[modern horizon]

might be to do with grabpoint, since thats where i grabbed it actually

[lunar sleet]

Get world location will usually give you dead center of the object

You can try line tracing to it for more precision

[modern horizon]

i am, but thats not in a event tick.... should it be?

i just put it in a event tick

it works

but it is now sliding and not anchoring onto the object

hence why i did get world location

[lunar sleet]

No need to put it on tick, you line trace when you aim at the thing and press the button

Then you get one result, not 60-120 results per second

[modern horizon]

yeah, but then the arm will stay in one place to whereever i grabbed it.

and not move the object around

[lunar sleet]

That’s more of a physics issue now, not so much about where you’re grabbing it

[modern horizon]

uh what? the place where i grabbed it is just not being updated

hence why it wouldnt move my hand to the object

[gentle urchin]

EventTick -> "IsGrabbing" -> UpdateGrabPosition

OnGrab -> IsGrabbing = TRUE;
EndGrab -> IsGrabbing = FALSE;

sounds like something one would do in the animbp

like ADS

[little agate]

guys, for damage number widget, on screen render should be more performance friendly right that world (widget component) ? is it worth for screen render implementation than world considering performance. or actually it is not a big deal

[surreal peak]

Widget Component itself is shitty expensive if you need to draw a lot. They will all count as an extra transform to update. You shouldn't use them if you want performance.

Have a Widget with a CanvasPanel and use a custom ActorComponent that can register to some manager that returns the world location of its owner.

And fwiw the widget that should be drawn.

Then do the math to place the widget on the CanvasPanel yourself

[little agate]

ah, thanks man, now I am sure then to not using it. yeah I consider it because damage number is dynamically added to world and a lot of them, so I have doubt using it, but screen render will have another complexity to implement. if it is worth, i will go there

[real cedar]

try using socket

[lofty rapids]

so you have it grab in the center, you want it to grab on the side or corner ? Maybe use a line trace like suggested, and just put the hand where the trace hits. Do the trace when you press the key, and put the grab point to the trace hit location ? this will grab wherever your trace lands. Do you want specifically a certain side of an object ?

[static flame]

Guys, I need help on how to make it so that when I press the pressure plate, the wall goes up? I can't find a normal tutorial and I can't do it myself

[lofty rapids]

wdym "press" ?

[lofty rapids]

probably just a door tutorial and instead of rotate move it up

if press you mean click it's easier then pressure like you put stuff on and the weight has to be something

[faint pasture]

Get a thing to print hello when you step on it.

Get a thing to move up when you tell it to.

Have the plate tell the thing to go up.

[floral stump]

What will be the best way to implement animations for +100 types of weapons?

Situation:
1: Weapon animations don't rely on IK bones.
2: All weapons has unique set of animations for upperbody pose: Base and Aim Offsets :: [crouch, prone, stand]

What I'm doing currently is?
:: Have a single anim bp class in which all the animations are implemented which is i think not the best way since i can have multiple anim classes which will be set by the weapon to the owner which is a the character.

but doing separate animation classes needs extra work like transiting the character to the old pose after setting the new class.

example:
Currently in AKM crouch mode
Switch weapon to m416 the character will transit to the stand pose with the new animation class which can be solved by a sync loading the new animation and set the old state crouch before setting it to the character.

[boreal basin]

I do have GAS Helper(the plugin) if that helps, since I'm new with C++

While for my Blueprint, I've put them all on the base BP_ThridPersonCharacter within the EventGraph as shown here: https://blueprintue.com/blueprint/bec2xiy-/

While the important components for said movement system as listed -

GA_Dash: https://blueprintue.com/blueprint/75qb8u4q/
DoubleInput: https://blueprintue.com/blueprint/6erq20kq/
DirectionToDash: https://blueprintue.com/blueprint/1illz9rr/

The main idea is to port all of my movement inputs as GAS Blueprints, for modularity reasons. Also I want to learn how to handle GAS effectively myself beyond RPG stats IMO.

While with Player Controller/Player State, its mostly setting them up in a Single Player context(so that I can use them for future MMORPG plans), moslty from here: https://forums.unrealengine.com/t/player-state-vs-player-character/319281

[faint pasture]

Weapon should carry references to the anim assets it uses.

[jagged moss]

why cant i convert enum value to name to get datatable row name, but i can convert the enum to string and string to row name and it works?

[floral stump]

Exactly this is what I tried, which reinit animation class on switch... means lost the old pose untill re notified or a sync load and set the old state and set to the character

one thing i didn't tried is make all anim classes derived from my base anim bp

not sure if it will solve it, but i think the base bp will have the old state and will just auto notify the child bp on switch

[floral stump]

enum values are uint8 internally, an integer index of a state

[faint pasture]

Name shouldn't be used in code

[spark steppe]

enum as rowname sounds like a painful life decision....

[jagged moss]

i use enum as its a fast way to grab the 6 rows i need in a specific situation

What i didnt understand was the difference between these to options

[spark steppe]

yea but i'm 99% that a gameplay tag would be the better choice to begin with

print the result and compare them?!

[jagged moss]

i printed and the print shows the same

[spark steppe]

https://tenor.com/view/side-eye-dog-suspicious-look-suspicious-doubt-dog-doubt-gif-23680990

[faint pasture]

Not 100% sure but might just not work at all in shipping.

Enum is a tarted up int. Don't rely on the name.

[jagged moss]

also the enums are numbers and row names are numbers

[floral stump]

DataTables expects a string as the name of the row not the integer

[jagged moss]

when using print string it also converts to string ofc, forgot that part, thats why i was confused

[fleet prism]

Hello, I'm having some trouble. You see I'm trying to get all parts of the wall to move currently when I press the button only one part moves not all. I've tried parenting and using children but that didn't seem to work at all still only the one moved. I've tried some other methods too but nothing seems to be working any ideas?

[floral stump]

@spark steppe

   public enum Status
   {
       Active,
       Inactive,
       Pending
   }

string rowName = Status.Active.ToString();
DataRow row = dataTable.Rows[rowName];

[spark steppe]

do i want to open rider now....

no

but i did anyways

TMap<FName, uint8*> RowMap;

[lofty rapids]

did you try grouping them ?

[floral stump]

yeah this should also work

if (DataTableAsset && ensure(DataTableAsset->GetRowStruct() == FOurLinkedStruct::StaticStruct()))
{
    for (const TPair<FName, uint8*>& RowItem : DataTableAsset->GetRowMap())
    {
        const FOurLinkedStruct* rowName = reinterpret_cast<const FOurLinkedStruct*>(RowItem.Value);
    }
}

[spark steppe]

fugly, but ok

[fleet prism]

yes, and still only one moved

[quick sigil]

Hi, not to be a wierdo, i'm new here and I was looking for developers to contact and your idea kind of caught my eye. (And yes, I did scroll all the way up because I have nothing better to do) I would love to assist you on your project, I just want to work. I can write and make music. I don't expect any pay. I have sent you a friend request. If you're okay with this, please accept it, but if you like to fly solo, you can just ignore it.

[lofty rapids]

you should be able to double click and switch between single and the group ? thats weird

[topaz goblet]

Been in a bit of analysis paralysis. I have a combat component on my actor for a tick based combat system.
It feels like I'm having it do too much, but it's making the component reliant on other components being on the actor, which seems bad. Like... needing to have health component, needing to have a weapon component, etc.
Has anyone done similar and ... am I approaching it poorly? My thought was... any player or NPC with the combat component can participate in combat. Combat component would be where I put ... calcs for hit, calcs for damage, mitigation, current target, who is attacking current player, etc.

[next hollow]

I'm currently in the process of something similar.
I would say, maybe it not NEED those, but make it interact with those.
Like, a combat component can still do combat, and if theres a health component, then it does damage.
Same thing with the weapon component.
Maybe combat can have a base like 10 damage, but if theres a weapon component, then do that much damage.

You could use interfaces to remove hard refs, or do abstract classes (1 BP file that has all the functions and vars created)
Then, a 2nd BP file that has the actual completed code, and filled vars

[topaz goblet]

Awesome, thanks for the input!
That's kind of the route I was going but started to feel like I was making the component do too much. Guess I'll keep at it and see what I need to refactor or whatever, when I get to it.

[next hollow]

Yeah, so far i've been keeping my components somewhat simple.
maybe a bit too simple, but it also removes 1 class that does like 80 things, when I really only need like 2.

[topaz goblet]

I was thinking about init of the combat component and then doing a 'get component by class' and if not valid, throw an error that the actor needs a health component, weapon, etc.
Similarly, I sometimes feel they're either too simple / not as needed, or make them overly complex. hahah

[next hollow]

Maybe needing a health component might make sense, but a weapon component doesn't sound needed.
But, that also depends on your whole game.
To me it would make sense to not need the weapon component, cuz maybe I wanna just having something fight, with a static value that isn't necessarily a weapon.

But, then to me I could split that into a couple components, to make it a bit more modular to me at least (but, like I said, I might be going a bit too far with my split up code)

[topaz goblet]

Oh for sure! It was one of the things I was stuck on. Because my NPCs have a different setup. Like, the player has an equipment system component that handles weapon, armor, etc. But, the NPCs just have a base weapon / 1 special attack'. Like... "claws, 1-10" or something simple like that.
For sure hearing your stuff helps a lot! Much appreciated

I'll have a default 'unarmed' simple damage

[next hollow]

Yeah, my current setup (while perhaps a bit much. 😛 )
Is I have an animation handler (for the replication of animations, and general handling)
Then, in the context of my game
The weapon component just handles the input, and cooldowns (since my inventory stuff handles the model being held by the player)
The NPC component is just an extension of the weapon component, but with more vars, for automatic attacking and the such.

Then, both of those components just detect anim notifies, specially related to damage, and then functions are called on them, about dealing damage.

[topaz goblet]

That sounds like you've done a lot!

[next hollow]

But, it also helps, cuz apart from the NPC component, the other 2 can be re-used.
Such as the weapon can be used for static mountable weapons, cuz the component just handles input, and cooldowns, no actual relation to like a weapon being held, or etc.
Its just told to send an animation request to the animation handler.

Then, the anim notifies handle dealing damage, or shooting projectiles.

But, thats also a big thing for me, personally.
Keeping stuff re-usable.
I don't like having a ton of 1 use components, or 1 component doing like 20 things.
When, 3 different components keep it split, and not require everything all at once.

[topaz goblet]

I recently watched:
https://www.youtube.com/watch?v=i_7p8-DE15g

And it had me thinking about a lot of different aspects of my project that need to be refactored and improved.
But, it also got me in the analysis paralysis mode. hahah! For sure helps hearing other experiences and how they're implementing.

[next hollow]

Yeah, it also helps to have a ton of prior experience, with the opposite of this. 😛
1 file that does like 500 things, and trying to wrap my brain around it, or work around it, when I only need like 5 things.

[topaz goblet]

haha, wow!

[candid osprey]

Is there a way for a sphere cast to ignore a object on the other side of a wall and get blocked

[dusky cobalt]

So when you detected some things with sphere, then you can do 1 more check for all of them with a line trace from origin.
Only when nothing blocks that line trace the actor will get added to ''detected array''.

1. Detect All Actors with Sphere
2. Check which ones I really see with Line Trace By Channel, make walls block that channel.

[modern horizon]

well, if i do that using the line trace i already have that only shoots once and use the grabpoint, then the hand just wouldn't move. if i use a line trace in my event tick function, then it wouldn't stay on the object and just disappear when i move it off the object

so i would probably have to do something like grabbed component world location x grab point/distance/impact point

[lofty rapids]

you can trace from a point outside the item toward the center and use that as the location

[modern horizon]

"outside the item" can you explain what this means?

[lofty rapids]

so you get the first point where you grab onto it

and the problem is it comes off of that point ?

[modern horizon]

yes, that would be grab point/impact point from when i first touch something.

[modern horizon]

the problem is, it doesn't move with the object

which is why i need to do something like grab point/impact point +/x/\ get world location of grabbed object

[lofty rapids]

so your grab point stays on say 0,0,0 but your holding the item and it's not moving with it the item is moving and your hand is still on 0,0,0 ?

tick would probably solve this issue i would guess

[modern horizon]

a line trace in tick means the cord wouldn't anchor, and just keep shooting and moving

[modern horizon]

ill show a video of what happens if i connect the grabpoint into the hand location.

[lofty rapids]

and on tick what happens ?

i can see because you never adjust the grab point

so it wouldn't work

it will just stick to the point

this makes sense

[modern horizon]

ill show a video of what happens with that,

i assume you mean event tick, right?

[lofty rapids]

yes, set the grab point to the location of the object on tick

that should put it in the center

and then you just want to offset that

[modern horizon]

well i want it to grab wherever i actually grabbed it, such as a corner

[modern horizon]

this code worked for me, distance of object being the distance variable from break hit point

but its not actually anchoring onto it

which is why i need to incorperate grabbed objects world location into somethling like this.

[lofty rapids]

start by grabbing onto the center

don't do whatever it is your doing in that video

it's a mess btw

[modern horizon]

physics handle > get grabbed component > get world location > anim bp grab point. boom center

[lofty rapids]

do the original trace

[modern horizon]

that was the event tick line trace

[lofty rapids]

just as you did

do the original trace

as you did

but on tick

[modern horizon]

uhm, wdym?

[lofty rapids]

set the grab point to the center of the grabbed item

[modern horizon]

how can i update that on tick

[modern horizon]

eh why?

[lofty rapids]

easy on event tick -> update value

get that working

then you can offset it

[modern horizon]

wouldnt that just be
physics handle > get grabbed component > get world location > anim bp grab point

[lofty rapids]

yes

most likely

[modern horizon]

alright, but that doesnt do what im trying to do.

[lofty rapids]

make it do that first

then you can offset it

i can type it a hundred times

lol

[modern horizon]

im setting the grab point to the center of the object.... can i just make a new variable, and set it to this

inside the tick.

[lofty rapids]

idk why you need a new variable ?

but you can do whatever you want

it's your code

[modern horizon]

i use grab point for grabbing the ground

ok

do i set the variable inside the tick, or when i grab.

[lofty rapids]

you set it on tick when grabbing == true

[modern horizon]

ok.

[lofty rapids]

ok so now you'll want to decide how you will offset this

do you want to hold it on the left, right ?

[modern horizon]

not specifically anywhere, just wherever the the point you looked and grabbed at

ill show a video of my old code and what it did. it might help

ofc it didn't anchor

but you could grab it anywhere on the object to grab it

[lofty rapids]

ok you maybe calc the offset by getting the center of the object and subtract the hit result and save that, and add that to the location 0

[modern horizon]

calculate the offset.... like the distance of me and the object?

or of where you grab it and the center

[lofty rapids]

"getting the center of the object"

"subtract the hit result"

and i think add it to location 0

[modern horizon]

center of the object would just be get world location.

i believe.

so it would be that - grab point?

[lofty rapids]

yes its close enough it should be the center

although it may be depending on your objects the bottom

but either way this should work

[modern horizon]

teleports the hands more behind me,

[lofty rapids]

don't do that on tick

[modern horizon]

alright

[lofty rapids]

get the offset
when you trace

then use the offset

[modern horizon]

i put that code after the break hit result/trace

[lofty rapids]

is it after you set grab point ?

[modern horizon]

yes.

[lofty rapids]

and did you set it to a new variable named offset or something ?

[modern horizon]

No... i just kept the same one

since im not setting it anywhere else

[lofty rapids]

it's a new variable

you want a new one

you want a new offset variable

geez

[modern horizon]

is offset a variable type, or do i just use vector.

[lofty rapids]

it's the result of the subtraction ffs

[lofty rapids]

vector

[modern horizon]

i don't understand why i would need a new variable for something that would have the same code?

[lofty rapids]

i can see that

[modern horizon]

am i editing it later?

[lofty rapids]

are you reading my writings ?

read what i wrote

[modern horizon]

Yeah i just don't understand...

ill make a new variable, still don't understand. what happens with location 0 after that?

[lofty rapids]

exactly what i wrote already, read it

[modern horizon]

and what happens now?

[lofty rapids]

the difference is one checks against the grab point for every tick
the other just does it from the start, and not when you move does that make sense.
you keep moving the grabbed the object this offset will keep changing if you do it the other way. you don't want that

[lofty rapids]

your doing this after the line trace ?

[modern horizon]

after the grab point is set, yes

[lofty rapids]

ok on tick add the offset to the world location before you set location 0

[modern horizon]

just to be clear,

offset 
                    >          location 0
world location

[lofty rapids]

world location - offset = location 0

basically it's current location minus the offset

[modern horizon]

wait, subtract or +

[lofty rapids]

try both

add first

if it's the wrong direction then subtract

[lofty rapids]

you definately want to add

but something wrong you are not grabbing that thing ?

it looks like the offset worked but you didn't drag the item ?

shouldn't you be holding that thing ?

[modern horizon]

i was, it was just a heavy object

i can show it again

[lofty rapids]

you really got to check your erros

you got an accessed none

and you've had the same warning for every time i seen your videos lol

[modern horizon]

wonderful

i think i fixed it actually

i just removed "get grabbed component/physics handle"

and plugged hit component

[lofty rapids]

whatever works

[modern horizon]

awesome.

thank you.

[cyan wren]

the way it generates cause the line traces to generate in a square

is there a way to make the spread circular?

i might just say screw it and go with the hurtbox shotgun method

[thin acorn]

I've got this event but I don't think it's working the way I think it should
PlaceWellScenery is an expensive function, so I only want it to run once a tick

PlaceWellScenery increments CurrentHeightStep, but even if I move the increment to the end of this chain it doesn't work.
If I print out CurrentHeightStep at the start of each LoopBody is just prints 1

[lofty rapids]

is place well scenery in the same bp as this one ?

[lofty rapids]

whats with the delay ?

i think that might fk it up tbh

[thin acorn]

All in the same BP
it works find without the delay, but the issue is it's justo too expensive so it hitches, so the delay is supposed to split up the expensive part into chunks

it seems While loops cant use delays tho...

[lofty rapids]

this is an offload to c++ thing i believe

you can make a function and run it through c++ this will solve your problem most likely

but a while loop is like that, blocking

[faint creek]

Hi guys, is there a way to rotate AI sight smoothly ?

[thin acorn]

try lerp rotator, from current rotation to desired rotation

[modern horizon]

so im trying to get a specific variable that will be inside several different blueprints/items. how do i check/reference a variable from several different bps
do i just do branches and keep casting until i find which one is the one im trying to reference?

[lofty rapids]

how do you not know which one ?

your looking if the variable exists ?

[modern horizon]

im just trying to explain it simple because people don't know what im doing, you know how im grabbing objects? im trying to get a value from the object im grabbing

problem is, there are several different objects that i can grab with a variable.

[lofty rapids]

you can make them all have a parent, and then they will have the parent variable

[modern horizon]

how do you do this?

[lofty rapids]

make one blueprint called PickUP

add the variable inside there

and when you want to make a new item

[modern horizon]

alright, ill try this when i can

ty

[lofty rapids]

right click and create child

then use the children as your pickupables

but you can just cast to the parent, and get the variable

because each child is of the parent, so you can cast np

but thats what i would do cast hit actor to parent

[faint creek]

Like this?

[thin acorn]

The Alpha is basically how fast to go from A to B, so 1.0 is instant
Try something like 0.1 or even smaller for a more gradual change

Also, you probably want ShortestPath to be true. Whenever to rotate, theres always a long way and a short way, and usually you'll want to rotate the short way

[faint creek]

I'm trying but it does not work

Could be maybe to turn in "Set actor rotation"?

[thin acorn]

Did you plug the cast in or is it just floating like that in the Blueprint?

[faint creek]

yes

[faint creek]

I've put it in teh EnemyPatrol Task of the BT, should I put it in the BP_Enemy with a Event Tick?

[modern horizon]

hey, so im trying to figure out if what im picking up is the specific mesh that is the actor bp, but it keeps printing false.

[stray halo]

this is just a general question to just gauge my terrible blueprint skills how long should it take someone (who has bp knowledge) to make a Minecraft style inventory with all the same mouse movements like splitting, single items, quick moving from inv to chest(all the goodies pretty much) also completely replicated ?

[thin panther]

There's not really anyway to gauge that.

It depends on your skill level, how much you've planned out, how fast you work, if you've ever done anything like it before, etc etc

Any amount of time is fine (as long as it's not for work), because that's just how fast you work

[stray halo]

understandable cause its taken me a little over a month and i don't know if thats bad or not, but you're right appreciate the response!

[thin panther]

The only time I'd be concerned is you're a month in and you've got nothing, or little to nothing so far. And only for the reason that you may find it more productive to start with a smaller thing and work your way up to build more foundational knowledge before you burn out. It's easy to get trapped in tunnel vision and end up burning out on something because you maybe weren't as ready as you thought yet.

If you're making progress, slow and steady progress but progress none the less and it's not just been a month of bashing your head into a wall just to have some empty boxes on screen, then I'd say refocus, take a break and try to figure out where you're struggling in particular

[next hollow]

Guess i'll put this here?
With the Download Image node.
What sort of usage do the images have?
Are they 24/ 7 in memory, and essentially a virtual texture worth of size?
Or, some weird like saved temporary to disk?

[maiden wadi]

I can't be fully sure. But assuming I'm looking at the correct code, I don't believe that it saves to disk. It looks like it just creates a Texture2D out of the received data. There doesn't seem to be any caching or anything either. So it's up to you to store it so it doesn't get garbage collected.

[next hollow]

I'm more curious about memory usage, or etc.
If I download like 100 images.

I just wasn't sure if it did some weird temp caching, in some files

[maiden wadi]

This would be like the same as loading up those 100 images from your content browser. They'll stay loaded as long as you keep a pointer to the image(this includes like putting it in an image widget since that internally keeps what it's displaying alive).

The single point of difference is that instead of having the image data in your project, you're receiving it from a download. Both end up putting data into a UTexture2D essentially.

[next hollow]

I just wasn't sure how textures work.

Don't actual texture files read from the file every so often, to update texture maps?
Or, are full files, also just 100% pushed into memory?

I also just wasn't sure if the dynamic ones had overhead, since they legit ONLY exist in memory

[maiden wadi]

Normal textures it depends on their settings. If they're not allowed to stream, they have to be 100% loaded from disk to memory before they can be used. I'm not 100% sure on the streamed ones, but I'm under the impression that they just give you a fast Mip0 that you can use immediately and then stream in the higher level mips over time. I'm unsure if they dynamically unload mips as you go though. My experience is usually UI where the mips don't really change much even if you use them cause they're based on screen space and that doesn't change usually.

[boreal basin]

Hope this explains it.

[atomic solstice]

Any ideas why "Destroy Actor" isn't destroying my controlled character actor and respawns leaving behind a copy?
Odd part is it still triggers Event Destroyed (and "Respawn Player") correctly

[ivory epoch]

I'm trying to set my CameraComponent to 0,0 by changing it in the Details settings. But the Details option doesn't show up for me?

[hardy merlin]

Put a breakpoint on the Branch node and see what you're actually comparing.

[hardy merlin]

Oh, looks like the top is getting a component while the bottom is getting an Actor (get owner).

Have Grabbed Component call Get Owner to compare actor to actor.

[desert flint]

still prints false

[hardy merlin]

Tried the breakpoint thing?

[desert flint]

this is a actor blueprint

[hardy merlin]

You can still put a breakpoint.

[desert flint]

okay, what would this do though?

[hardy merlin]

And manually inspect what it's actually comparing.

When you hit a breakpoint you can mouse over the blue output pins and see what value they have.

[desert flint]

how do i do a breakpoint?

[spark steppe]

rightclick the node

[onyx tapir]

Or f9

[boreal basin]

Where do I start?

[severe coral]

Thank you for the advice. Sending message to the game state is indeed very easy, I'm just using 'GetGameState' and sending it with an interface. But what about updating values in widgets from the game state? I created an interface function with inputs, but I still need to use 'GetAllWidgetsOfClass', right? Is this optimal?

[barren tangle]

Is there some people that use the motion warping node ?

The Warp Target Bone Name?

do you know if it move that bones to the location?

if it's not empty?

[lofty rapids]

Did you mak a parent class ? You can cast for this

[lofty rapids]

are you switching names ? wdym not alts ? are you doing the exact same thing as someone else ? wtf is going on here lol

[narrow sentinel]

asking in here as well as this issue seems to happen when doing it through pcg and not pcg. So I have my spline and if I do 90 degree corner the spline mesh gets twisted and I can't see to get it to fix unless I put it slight off 90 corner

[rose crest]

Event destroyed is called frame before destroy. You have some gate there. Maybe it block destroy event

You can try to print actor self on event tick and see if it's valid, also breakpoint. Also maybe just call event on controller on destroyed/death

I'm mean for game mode. Not from character that's about to die

[lunar sleet]

You should not have code after destroy is called, for starters, that’s prly what’s causing it. Use visibility to hide it if you need to run stuff first and then destroy when you’re completely done running code

[faint pasture]

Everything but the UI is piss easy

the UI with the dragging and dropping is the most work

[faint pasture]

I'm doing a quick and dirty prototype with abilities as actors, all subclasses of BaseAbility

What's the simplest way to map inputs to ability instances in a generic fashion?

Right now when I spawn the ability actors from an array of classes I just do a cast chain to set up MySprint and MyJump and MySuperPower etc, feels dirty tho

[maiden wadi]

They're actors?

[topaz goblet]

I have a base class that I used to have a mesh for, but converted it to a base class / abstract. When I did that, I cleared what was in static mesh, but it's still showing up in the content drawer.... what should i check? Do I just need to refresh something?

[faint pasture]

Yeah just for simplicity + to have timelines in them

[maiden wadi]

What do you mean by still in the content drawer?

[faint pasture]

It's a quick and dirty single player thing

[topaz goblet]

Base and dummy showing the mesh. But no mesh applied to Base

[maiden wadi]

Can't you just put the inputs in them directly, like implement the IA in the ability actors. Like IA_Jump goes in MyJump. Then you can just loop them as the base class type and EnableInput?

[maiden wadi]

Ah. Thumbnail didn't update. Can't recall how to cause that to refresh. Compile with the viewport actor or save?

[faint pasture]

https://tenor.com/view/batman-thinking-gif-18107621495886085895

That's a pretty slick idea

Although mapping it to AI driving these things around would be a bit weird too

maybe gameplaytags

[topaz goblet]

Ah, okay. I thought it might be a thumbnail issue not refreshing. I've closed the editor, restarted, recompiled, saved all, removed child actors from the scene, etc. Eh, not a big deal, just thought there might be a simple button i missed.

[maiden wadi]

I think that's how GAS does their stuff kinda. I've never looked how to map IAs to their input keys you use. Lyra does it for GAS somehow. But yeah activate by tag would be a good one if you need AI activation by type.

[faint pasture]

I'd just like to make AI able to query to figure out their bodies capabilities

"Do I have a way to move fast?" etc

yeah tags might be it

[desert flint]

i have 2 accounts here, one was my previous. this ones my new, but im still using my alt so sometimes i forget which one im on

just ignore it.

[desert flint]

well one of them is my actor (where this code takes place) and im casting it to my character bp.

so how would i do a parent class thing?

[lofty rapids]

you want a variable on all the things you can pick up that you can access right ?

[lofty rapids]

^

[desert flint]

well what im doing is, making it so theres a variable in my main character bp, that all object bps will cast to, and add their value to that variable if they get picked up

[celest oar]

having a bit of an issue setting values in a dynamic material in runtime

it prints the correct number but its not setting

what am i doing wrong here?

[lofty rapids]

idk what that means

[desert flint]

alright wtv

so

how do i fix the = sign thing

thats my issue.

[lofty rapids]

you created the material instance, but did you assign the material instance to the mesh ?

[lofty rapids]

cast to the parent
i'm not going to keep repeating just read it

[celest oar]

i assumed it would assing automaticly since you drag it fro mthe mesh node

also the material shows up in the mesh

so it should be there

[lofty rapids]

ok well you have to assign it because you created a new instance

so just assign the material onto the mesh and it will most likely work

[lofty rapids]

it's not the same instance

your creating a new one

[celest oar]

just tried it, thats not the issue

[lofty rapids]

that is definately the isue

show what you did

you cant just create an instance and it magically works with a mesh

you need to assign it

set material node

plug the instance into it

[desert flint]

what do i plug in object?

[lofty rapids]

wtf are you even doing ?

[desert flint]

🤷‍♂️ you said cast to parent.

[lofty rapids]

so alien egg is your parent class ?

[desert flint]

more than likely

[lofty rapids]

you don't need mesh plugged into target, what bp is this ?

[celest oar]

its just an actor derived from a custom c++ class

[lofty rapids]

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

[lofty rapids]

dont drag out from mesh, just create dynamic material instance

[celest oar]

behaves exactly the same

[lofty rapids]

so is the default material working ? set the material to something like the grid

then set this material

is the basica thing working with no setting changes ?

[celest oar]

default material works fine

[lofty rapids]

is it applying ?

is the question

as far as works fine, you want to test to make sure the material is being applied

first thing

[faint pasture]

The thing you want to check if it's an ALienEgg or not

[lofty rapids]

if it's being applied then your probably not setting the correct param name or something

[faint pasture]

You 100% sure your parameter name is correct?

looks like aMount

[abstract locust]

Can anyone help, everytime I try to delete this variable from my player bp it try’s loading in all the referenced actors to it and ends up crashing. Is there anyway I can change this variable so that it’s empty before I delete, because even if I change it to a bool or something it still gets all the references

[lofty rapids]

you can try the option to replace all references when you delete

[lofty rapids]

i'll say it again ig, check to make sure the instance is being applied

start with the grid material

create the instance

set the material

does it change ?

[abstract locust]

How do I do that

[celest oar]

got it to work, it was an issue with the default value of the variable i was using to set the value

[abstract locust]

This variable isn’t being referenced in the actual bp I’m trying to delete it from

[lofty rapids]

so show what you see when you delete the variable

it should say theres a bunch of references

does it mention you can replace ?

maybe actually i'm thinking wrong window

[faint pasture]

debug that, there's a render debug scalar node

[abstract locust]

No it just shows loading referencing assets loading bar

And then takes forever and eventually crashes

[celest oar]

its working now, sorta

[lofty rapids]

right click, and do: replace references ?

[lofty rapids]

well thats not good lol

[lofty rapids]

you don't want ==, the cast is the check

you should watch the video i sent

[lofty rapids]

^

[safe sigil]

Why is the delay not executed? Does anyone have a solution?

[dusky cobalt]

how do you know it's not? it's 45s delay

print something before Ferting function call

[sick sky]

or add a breakpoint

[safe sigil]

I know because a video is playing

[sick sky]

?

[safe sigil]

it's just the delay that doesn't work

and a 2 second delay works

=/

[dusky cobalt]

every time you click that button it starts that delay over again btw

[safe sigil]

i know its a Start button

[dusky cobalt]

are you maybe deleting that widget that this delay is inside?

also i'm not sure if you can open level from the widget, you should make this call to GameMode probably

[maiden wadi]

That only happens with RegriggerableDelays. Normal Delay just ignores you til it finishes it's original timer.

[safe sigil]

yes but I think I have the problem you are not allowed to tab out

[dusky cobalt]

so create delay + open in gamemode, and call function on gamemode from widget

[safe sigil]

okay i try

[lofty rapids]

at this point use set timer by event, thats quite a delay

[safe sigil]

I've already tried it, it doesn't work either

[maiden wadi]

Lol, I didn't even see the time.

[desert flint]

so it only executes this code if it is casting? or what.

[lofty rapids]

if the cast succeeded then it will run

[maiden wadi]

What do you mean by "if it's casting"? Cast is just a type check. If Owner is an AlienEgg,then this will print.

[lofty rapids]

it does work, print string hello on the timer

[safe sigil]

it does but the delay dont

[lofty rapids]

what ?

i don't know what that means

the print string prints ?

[safe sigil]

yes

[lofty rapids]

so then it's working

[safe sigil]

but the timer dont work

[lofty rapids]

your not making sense

[safe sigil]

i know

[lofty rapids]

show the code @safe sigil that isn't working

[modern horizon]

Is get owner the correct thing for it? As I feel like I would need to do something to get the mesh that I’m picking up, or the actor. Something other than owner

[lofty rapids]

probably not the right thing

what bp is this in ?

[lofty rapids]

the print string is before or after the delay ?
put it after the delay as well and check it goes off

if you restart the engine

and it's still doing it your probably doing it wrong

[safe sigil]

let me try one thing

[lofty rapids]

try many things

lol

[safe sigil]

XD

[safe sigil]

okay i found it it's UE5 fold

sorry

[topaz goblet]

Hmmm, trying to build a small test area that is an empty open world. created a small thing, went to env light mixer after, added sky atmosphere and sky light. But... everything is black. After adding those, they appear to be above the landscape I added, but nothing is being lit...

The prebuilt open world thing works well. But, it's huge. Just wanting a small one to mess around with.

[desert flint]

the actor one

[lofty rapids]

what actor ?

i would do get grabbed component -> get owner ?

not just get owner

if anything

[cobalt pelican]

Is there a way to set a property binding up for a new member you have created from a blueprint?
Would like to have something exposed on my blueprint like what a slider does for some other UI widgets I have created.

[sick sky]

you shouldnt use bindings in widgets

each tick the widget will get and apply it

[faint pasture]

and why is that a problem?

Binding is fine if you only got a bit of UI, and it's probably the best approach if the data is updating often like regenerating health

You wouldn't want to bind for WoW or EVE but it's totally fine for a couple health bars

[sick sky]

usually its abused so i would ban it

unless its something updated very frequently i would always make an OnMyPropertyUpdated function and call that when a value changed

[topaz goblet]

Is there a way to see if a UI has bindings?

[lofty rapids]

I tried to interpret on binding and it didn't work so I wonder why that is ?

[maiden wadi]

Lol... If you've ever scripted Lua for WoW addons.. Trust me.. You'd want BP bindings after that shit. 😂

[topaz goblet]

Feel like I'm doing this really wrong. lol. What's a better way of doing this?
it works.... unpause timer once I stop running, pause timer when I'm running. For stamina regen.

[faint pasture]

show more

when is this code ran, and what's that bool

[faint pasture]

Why do you go through all this trouble instead of just changing staminaregen based on if you're running or not

[topaz goblet]

Haven't found a better place to put it yet, that functions as needed.
I was just eyeing the movement area of my setup, possibly doing it when transitioning from running to walking. But, I think before I ran into issues of just standing still ,caused it to not regen. Or, if I transition from running to stopped, it keep draining.

This was a hacked together solution for the time being. but, decided to get back to it.

[faint pasture]

TimerFires -> are you running? -> yes -> no stamina for you
-> no -> ok here's some stamina

unless you really want the stamina regen ticks aliasing and pausing like they will with your current setup

[topaz goblet]

Is there a check for 'is timer running' ?

Ah dang...

[faint pasture]

if not you can make a bool, but you're overcomplicating it

[topaz goblet]

is timer running. haha

Thanks!

Oh, for sure I had a feeling I was overcomplicating it. Late night ... "I'm gonna make this MF work!" hahah.

Thanks!

[kind estuary]

is it bad to pass a struct by reference in Blueprints?

Im getting this warning:

and also, i get a super weird crash, like ive never seen before

[maiden wadi]

Passing a struct is fine. The warning is just telling you that this interface function will not affect this struct.

It's essentially warning you that the interface is a const FMyStructThing& StructName. It's by ref, but const. You can't write back to it.

[kind estuary]

[covert ingot]

hi, im doing a widget blueprint and am doing a gamemode container box using a data asset and i cant figure out whats wrong. Does anyone have any experience that could help me out? Its very simple at the moment i guess its just not clicking for me.

[warm hare]

So my character just randomly stopped sprinting. I did a key check but it still doesnt work. All the character will do is sprint when you initially press the left shift, but then nothing. I haven't even touched the sprinting logic, because it has been working as intended up until this moment.

[topaz goblet]

What's the purpose of that bottom branch?

I don't see anything in that logic that would be a cause... maybe somewhere in the IA key stuff?

[graceful sage]

Prob never passing the first branch cause its not set true unless already true

Prove it to false

Move

has anyone been able to get plugins that are not mac compatible to work?
i saw you can force it by changing some text files and adding mac to the whitelist but have't had any luck with it

Hey if anyone could give insight into why my Material Preview is completely black it would be super helpful. Findings in the post below:

[crude spruce]

I made a 2d array struct in c++ and cant help but feeling weird using it in blueprint compared to perform unflattening operations on a 1d array.

curious on if people prefer one way over the other for those of you that dabbled in both?

[hardy merlin]

Is there a way besides Nav Modifier volumes to annotate the nav mesh? I want to be able to define 2D areas of the nav mesh as "territories".

For AI purposes.

[crude spruce]

you can do that with nav mod volumes

or rather, you have some agency in the volume purpose

[mental trellis]

Depends if you need to resize each array. In a 2d array, each sub-array is separate memory and you can reallocate much easier.

[crude spruce]

good call

i love this answer i will keep the thing and flatten it where it makes sense

[hardy merlin]

My apprehension is that I might need a more complex shape than a box or cylinder. Am I able to check if a given nav point is wihtin a specific nav modifier actor?

[hardy merlin]

Working with arrays in BP is a big pain. I'd go with some kind of boxed array object.

Then you can make your own interface.

[crude spruce]

ask this and know you can do any thing

your approach most likely depends on the usecase and more specifically the system that enables or warrants the usecase

for any actor to know where they are they need some sort of local knowledge, if navmesh can pass that via custom volumes i have no clue

if the game is wholly 2d, you can do lots of other cheap stuff

[hardy merlin]

Sure. My use case is I am making a dungeon-crawler game and need to be able to mark sections of the navmesh as territories. My AI characters will be assigned to a territory and their AI will change when they are inside or outside it. They will also have an Inner territory and an Outer territory, where if they exit the outer territory they are forced to run back until they are back in the inner.

The game is 3D.

[crude spruce]

but it can be as simple as switching local knowledge enums with triggers volumes that are unrelated to navmesh

[crude spruce]

i ment 2d as in the topology/level design/architecture does not enable actors on multiple stories as an example

[hardy merlin]

Topology wise it can have multiple stories.

[crude spruce]

either way think of the simplest solution. if we assume your crawler is proc gen for layout, look at your smallest common piece of dungeon layout, how do you refien those? can you add "territory volumes"?

[hardy merlin]

It's not procgen.

This will be authored.

My concern is: making complex shapes, being able to recognize some quantity of volumes as a group, and being able to manage it all.

[crude spruce]

Ok so 1st thing i would do is to look into nav mesh volumes and see if they can act as behavioural switches

what is a complex shape?

[hardy merlin]

I just had a realization: The number of volumes that actually overlap are going to be very low. Almost all will be edge to edge, barring some sincerely complex shapes.

One with concave edges.

[crude spruce]

or rather, why would a territory shape need to be complex

[hardy merlin]

True. If I imagine a square room with 3 corridors leading out I can represent that with four boxes.

[crude spruce]

also if you try to name the component of the design for what it does, it usually helps in its conception

territory volume, behavioural switch volume, etc etc

@hardy merlin also would it makes sense if the ground was managing the information? just to present an alternative that doesnt require extra management to the level outside populating existing aspects with extra data

[hardy merlin]

Unlikely. I'd have to annotate every prop the player could walk on. The navmesh already does that for me.

[crude spruce]

fair

[opaque wagon]

So my character just randomly stopped

[dense hinge]

Hello, Is there a way to set the landing point on Predict Projectile Path by Object? So that if it's between 0 - 1000 it'll hit any object inside that range?

[crude spruce]

break it down a bit. what value is between 1 and 1000

[dense hinge]

I'm making logic to allow a character to jump between ledges. I'm using predict projectile on path to find the ledges. 0 is in front of the player, 1000 is the max distance the player can jump

[crude spruce]

im not familiar with predict projectile path. do you already have it working to some degree?

[dense hinge]

Yeah, but it tends to overshoot for anything that's not at the correct length. So, anything that's closer to the player ends up ignored

[crude spruce]

which aspect is being ignored? collection of actors in the path?

[dense hinge]

Yes

[crude spruce]

What is the simplest usecase for the prediction? what are the inputs and the expected return?

[dense hinge]

Input is movement velocity, and the expected return would be to find any tagged object so it would snap to it. I've added a video. The first jump should have landed, since it's in the range

[crude spruce]

without knowing how it works at all but looking at the green spheres, it looks like the capsule midpoint hits in the edge of the shape and slides away.

this looks like a miss if im interpeting the visuals correctly

and the collision points looks like they hit the edge

what is the snap logic?

[dense hinge]

This is what I want it to do.

• Green is the usual jump path
• Orange is max jump distance
• Black square is any ledge / beam
• Blue is jump path adjusted to the beam

[lofty rapids]

you may want to predict many paths and use the one with a hit at that height

[crude spruce]

ye

or trace in the prediction

its a complicated intention

[crude spruce]

im assuming orange is 0 to 1000 ?

whats missing here is how you jump. Is the jump an action product from the prediction?

[dense hinge]

No, I'm jumping and calculating afterwards using the predict projectile path

[crude spruce]

how would you alter the current jump trajectory to fit a new path?

or rather, override the current trajectory with a new one

[dense hinge]

That's why I wanted to see if there's a way to calculate trajectory using the landing position

Even if it's using a different node to launch the character

[lofty rapids]

Doesn't predict projectile path require a force?

[dense hinge]

Yeah, a velocity input

[lofty rapids]

theres also custom arc

[dense hinge]

Oh, ok. i wasn't aware of the custom arc suggestion. This might be what I'm looking for. Thanks a lot

[severe coral]

Hey Im wodnering why sometimes when calling interface there is word and symbol of message and sometimes its just like function? If I turn off context sensitive there is always option with message. What is the difference

[broken wadi]

Interfaces allow for blueprints to communicate to one another without casting. Say for example you have a door that you want your character to open. You can implement the generic sounding "interact" event on blueprint "door" so that whenever its called by another blueprint it can perform the logic to open the door.

Then on the character blueprint you can have an event setup that does a linetrace and whatever actor it hits it can send the "interact" message to.

Once your character is setup to "interact" with actors in the level, you can simply make a new blueprint for weapons or items and implement the "interact" event on them to perform different actions.

The benefit here is that when the linetrace hits something it doesn't matter if the target actually does anything with the "interact" message its being sent. It's like a fire-and-forget type of behavior that doesn't create a hard reference (because there's no casting or variable reference) thus keeping your memory usage in check.

[severe coral]

ou you misundertood me, bnut thank you for clarification. What I meant is why sometimes there is no (message) when typing interface name like in screen above, and I have to uncheck "context sensitive" to see it

[true cedar]

Hey everyone,

I’m trying to set up a resolution settings list in my UE5 Blueprint UI. Here’s my current BP setup for populating the resolution array (snippet below). I’m using GetSupportedFullscreenResolutions, but for some reason it always returns null; and thus goes into the fallback mode I added..

It seems like the array from GetSupportedFullscreenResolutions is always empty or the function fails, even though I’m testing on real hardware (not a VM).

Has anyone run into this before on Linux (or generally)? Is there something I’m missing, or do you know any alternatives/workarounds to get supported resolutions reliably?

Thanks in advance!

[broken wadi]

When you drag a pin from another actor you can call any message using the blueprint interface

[final mortar]

I've got some noob question, I am trying to revert a Rot variable from my character to a vector 2D, basically to be able to have X Y variable as inputs

[maiden wadi]

Need more context maybe. Not following what the rotator needs to be converted for the 2D for.

[north lynx]

Hi all!
I'm trying to setup some interaction system using VR Template and this tutorial: https://www.youtube.com/watch?v=peQq9f_EtrE
After I set all up, lever is working, but it is super sensitive to the movement of the hand, like even the slightest movement drops it all the way to the other end.
Any idea how to change/adjust it?

[maiden wadi]

That's interesting. I've never seen that fail before. But I've never tested it on Linux. Is there any chance you have a Windows build to try it on?

@spark steppe might also have some insight here if he's ever tested anything similar. I know he's a Linux user.

[spark steppe]

no idea, i'm not targeting Linux (only using it for dev)

[final mortar]

It's a bit hard to explain but basically I'd need to revert some Rot into X and Y action value

also, I am only using Yaw Value (Y)

[lunar sleet]

Lol

Not sure if that’s even possible, but why are you trying to do this? Maybe there’s a better way

[lofty rapids]

"revert a Rot variable from my character to a vector 2D," ?? "as inputs" ? huh ?

[opaque wagon]

can u give whole bp code screen and more detailed about ur idea. i think we need more info

[lunar sleet]

He’s trying to turn actual rotation into action values which are very different things. @final mortar if you print out those action values you’ll understand what you’re trying to do is not feasible. But there’s likely a better solution for what you’re trying to do, you’ll need to explain what that is tho

[lofty rapids]

i still don't know what that means, the rotation controls the action value ? for instance is it 0 rotation to 360, where 0 and 360 are something like 1, and 180 is -1 ?

[lunar sleet]

Yep

Least that’s the way it’s coming across

[lofty rapids]

"The cosine function naturally gives you this mapping" -AI

perhaps if its just one angle like z the math would be pretty easy

[lunar sleet]

What does that give you exactly?

[lofty rapids]

cos(0)    = 1
cos(90°)  = 0
cos(180°) = -1
cos(270°) = 0
cos(360°) = 1

idk if thats exact what they want but theres math for all sorts of mapping

[lofty rapids]

then you can offset by whatever to have your start angle and get your range

cos(angle (- or +) offset);

[north lynx]

Any ideas on this topic? 🙏

[faint pasture]

no tick or interfaces
100 hz timer

that tutorial is ass

[north lynx]

Literally there is no other way
Every tut that I found uses that way

[spark steppe]

because they probably all copied from each other 😄

set the lever position to the initial hand/controller location when the interaction started?!

so that the movement "in VR" maps 1:1 to the virtual world (i think it's what they trying to do)

[north lynx]

Yeah that's kinda f* up

[north lynx]

That's what I'm doing I guess

[spark steppe]

yea, looks like it, but apparently doesn't work!?

[dark drum]

I would probally get the look at rotation from the lever base and the hand position. Locking the rotation to a given axis. Interp between the current and new rotation and it should look pretty good.

[spark steppe]

maybe the issue is that you map the offset to the rotation

i would suggest to slap a map range node between that

then your output range is -60 to 60

and the input range you gotta play with (or calculate :P)

[north lynx]

Works, but the lever just flicks between two end points...
And when I have my hand in the air above the lever, it wags like a stray dog

[primal locust]

hello, i need help, I'm making car drivable in ue5.5, in that i have make it drivable but my car is drifting a lot. please help me to make it run smoothly like a real one.

[spark steppe]

also adding the existing roll to the value might be wrong

[spark steppe]

#chaos-physics is a better place for this

[primal locust]

i have use chaos physics still it get drifting.

[north lynx]

Between where exactly?

[spark steppe]

instead of your clamp node

and eventually don't add the existing roll, because i feel like this may be the main source of your flickering

[north lynx]

Alright

Bout to test it out

[north lynx]

I guess

[spark steppe]

yea wait i've interpreted the thing wrong at first, sorry

[primal locust]

brother this is for my problem?

[spark steppe]

does grabbing the lever move the GrabComponent?

[primal locust]

i have make it in bp_car?

[north lynx]

GrabComponent is part of the whole

[spark steppe]

you have to learn the english language, i told you that the channel #chaos-physics is better suited for your issue

[north lynx]

Now it's only waging like stray dog all the time from one end point to the other

[spark steppe]

ok, i have an assumption about how this is supposed to work, revert to the original node setup

and get sure that GrabComponent is located at the end of the lever

[topaz goblet]

In terms of 'Pure Functions' I saw the whole can't set variables thing. Does that apply to local variables as well, or just no modifying anything outside the function itself?

[north lynx]

It is now

[topaz goblet]

Like, if I need something in the function to run a total of items, but use a local variable to store them

[spark steppe]

also their code expects that the lever movement is on the Y axis, is that the case for your setup?

[spark steppe]

that's fine

[north lynx]

I made sure that my axes were working correctly, even if they were different from those in the guide.

Cuz it is taking rotation from the lever (in axis I want it to move) and location axis I want my hand to move while holding the lever

So in my case it's Y location and X rotation

When grabbed, lever should follow position of the hand by Y axis and rotate itself in X axis

[spark steppe]

so did moving the grab component change anything?

[north lynx]

Don't know cuz the meta quest need an update so I'm waiting

F* meta

Hate this stuff, but can't afford anything better

[spark steppe]

oh my condolences for working with a quest...

[north lynx]

Yeah

[faint pasture]

you SHOULD be using tick.

You want the thing to be in a valid location per frame

per frame = tick

[spark steppe]

i think it doesn't matter?

[north lynx]

I have timer

[spark steppe]

since it just maps the relative location to a rotation

[north lynx]

That works only when grabbing the lever

[spark steppe]

and the quest will likely not hit 100fps anyways (guessing he runs native) 😄

[faint pasture]

so multiple updates per frame

it's not the problem but it is a problem

[true cedar]

I just found a thread on Reddit; where a user mentioned that games on Linux with fullscreen; actually use windowless borders.. It wasn't related to game-dev; more gamers in general.. but I now opted for checking OS name; if not Linux proceed. On Linux just insert a default resolution range. Thanks for the reply 🙂

[faint pasture]

A pure function should return the exact same result given the same inputs, and not change any state anywhere.
BP lets you do all sorts of busted stuff in a "pure" function but that's the intent.

[spark steppe]

yea, max once per frame should be ticked

[faint pasture]

at that point it's just tick with extra steps lol

without the ability to choose per or post physics

[spark steppe]

it won't change anything tho behavior would be the same with multiple ticks per frame

[topaz goblet]

Ah okay!

[faint pasture]

all that math is goofy. Just cook up a relative rotation to point at the thing, then restrict it on whatever axes you want

inverse transform position, find look at rotation, then limit

[north lynx]

Yep, it flicks to one side and then freezes

Like literally can't make it move

[spark steppe]

is the lever placed in the world to move along the y-axis, too?

[north lynx]

Yep

[faint pasture]

Because that math is wrong

[north lynx]

Idk 4 tuts using this and it works

What if I use PhysicsConstraint?

[mental trellis]

Tutorials don't always show you good practice... Or working code.

[faint pasture]

physics constraint will do the job if you want it to be physics driven

[north lynx]

I mean, I would like to snap the hand to the handle and then move along the axis

This tuts aren't what I'm looking for either way

But I wanted to check how it works

[faint pasture]

You want to snap the hand to the handle or the other way around? Seeing your hand go where it's not in VR would be kinda silly

[spark steppe]

the half node is a break vector node

would try something like this maybe?!

[faint pasture]

All of that math is fucked, not at all worth even considering

[spark steppe]

i have a hard time twisting my head around it right now

yea, mapping the linear movement to angular rotation like this is... wild

[north lynx]

But there is no way to make angular clamp

or anything like that?

[faint pasture]

If your goal is "handle points towards hand" then it's this simple.
Convert hand world location to relative location in the reference frame the handle is in (inverse transform location)
Cook up the target rotation using FindLookAtRotation
Break it up, only using the pitch or yaw or roll that you want

Of course you can do an angular clamp

If FindLookAtRotation doesn't work for you (it might not depending on which axis you need to be the free one), then RotationFromXY or any of the varieties will do it

[north lynx]

And pin it to event tick or what?

Cuz now it looks like that and literally don't work

[faint pasture]

You're mixing up world and relative coordinates there

I was remoted in to my home computer so the mouse is a bit jiggly

[north lynx]

Still wags like stray dog

[north lynx]

Whoops Motion Controller should be GrabComponent but you wouldn't guess it
Now it stays in one end

Forever

Idk basic mechanics always don't work for me
I managed to program flashlight that charges when shaking all by myself, but can't make F* lever to make it's thing 😩

Idk maybe it's because you are on FP Project and I'm working on VR

[tribal gazelle]

Here is a tip I worked out when referencing stuff. Create all of your references (character/mesh/capsule component etc) inside a single actor component and reference that component in all other actor components instead of having to create all of those references over and over again in each component.

[faint pasture]

Shouldn't matter, show what it's doing

[faint pasture]

huh? How would that work?

why do that? Are you doing like:

Get component by class -> get the refs?

[tribal gazelle]

Inside your actor component, get the owner of component (pawn reference) and cast to character then get component by class and use a single reference component.

Then get your character, controller, mesh and capsule component references inside that component. Even the anim instance etc.

This way you are referencing a single variable - not repeating those variables over and over in each component.

This is assuming your features are broken down into actor components. I do everything in them.

Also, you can easily access it via the get component by class node and totally avoids having to cast to the character.

Like I have my main UI inside an actor component. Much easier to access.

Once you start storing variables in the character blueprint, you now have to cast to it to access said variables. Unless that variable is in an actor component then you bypass having to cast to character and just get component by class.

[faint pasture]

I mean casting isn't a problem here

Either way the character class is getting loaded

[tribal gazelle]

Casting to character etc. is fine as they are already loaded onto memory. I mean your BP_MasterCharacter.

[faint pasture]

Yes, and they are already in memory because they're being referenced by your component

[tribal gazelle]

Once you create a character class, it's now a hard reference which is not loaded onto memory. If you do your actor component references correctly, you just use the base classes like character and player controller and you have enough to do your functionality.

This way you can attach it to any character to add said functionality to it.

[faint pasture]

Yes, or just cast to BaseClass. It's all the same memory wise, you're not saving anything.
It might be more expensive doing all the get component by class queries if you're doing that at high frequency

[tribal gazelle]

My point is doing the cast once, in a reference actor component. Not having to do those references again and again in each actor component.

And referencing that single variable. Not making heaps.

[tribal gazelle]

You store the reference component to a variable on begin play for each new actor component.

Then you have access to all types of references. And you do those references once inside your reference component.

And if you need to use just the get component by class node, like for begin overlap events, you're only referencing a single component - the reference one.

And if for some reason you need to access a class, like BP_ThirdPersonCharacter, you just use an interface with the base class reference. In this case, character.

I forgot to mention, all of the other actor components are referenced in the reference component, giving you access to all other features/components.

Considering each feature is done in individual actor components.

[tribal gazelle]

I'm pretty sure they are already loaded onto memory by default as they are C++ classes.

I mean, Character > Player Controller etc. but BP_ThirdPersonCharacter for instance isn't.

[fleet prism]

Hello, I have a platform that moves up when you press the button once. But id like to know what I need exactly to make it come back down on its own without me having to press the button

[tribal gazelle]

Try this. Make a custom event called "ResetPlatform" then off the finished pin of the timeline call that event. Then plug that event into reverse pin on start of timeline.

Oh sorry, off the finished pin do a delay then call event
