blueprint

[lean schooner]

does using statetree or BT offer better ai performance than just designing exact same behaviour in a blueprint event graph?

[dark drum]

I would imagine it would depend on what you're actually doing. If it's pretty basic, there probably won't be much difference.

Is there a reason you're thinking of not using the built in solutions?

[lean schooner]

oh its just that i already designed a fairly robust ai system for my NPCs in blueprints , i am about to add quite a lot of functionality to it, so i was thinking that if i was going to swap to another solution, i should be done now

i am not finding my blueprint solution limiting right now, i just worry about performance once i have a few 100 of them running around a rather large landscape

[dark drum]

It's difficult to say as it would depend on what you're getting the AI to do and how you're managing the various checks.

The best thing to do is spawn 100 NPCs in that use your system and see what happens. Even if it's just them moving around and doing some basic actions.

[lean schooner]

yeah, i will spawn lots and see what happens! i have my population limit at 25 now and it handles that just fine. the npc ai i am discussing is a pawn that replicates a human mmo player running around a world, fighting monsters, looting, visiting shops etc

i have arrays managed by another BP which stores the locations of everything the npc would ever need to find so there is quite little they actually need to "think" about tbh. i will just keep working on my blueprint/smartobject system until i run into problems, it works good so far and i feel comfortable developing it

[fringe junco]

as you can see in the video the inventory mostly works but there is a slight rotation bug at the end with the payload widget. im not sure whats going on as previously the wrong widget would rotate (lol), but this is atleast a clue.

[dark drum]

That would depend on the var type, if it's an object you can check if they are the same object using the = node.

[tight pollen]

hi]

[wraith raptor]

Would anyone know how to return the level being used in a level instance? The name of the actor is different from the level being used.

[gentle urchin]

No you cant

[thin panther]

Tell us what you're trying to achieve. This sounds like a classic XY problem

[ebon olive]

hi guys what i did wrong here? 😦 why doesnt my "boost" got activated?

[gentle urchin]

You can pass around a pointer to a single object, yes

[versed sun]

try this, and -10 seem super high for on tick

[thin panther]

Simply. You don't. No has no concept of memory addresses

You have references, which are only uobject pointers

Other than that, everything is a copy

[ebon olive]

didnt work 😅 sorry haha. this is really hard 😦

[versed sun]

Crank the 10 , -10 down to like .5

[modern radish]

I have a simple question, does the Sequence node wait for the loop to conclude?

[gentle urchin]

Yes, as long as theres nothing latent, its all running on the same thread, in the logical order it can

[versed sun]

You can also just get the IA_Boost value and plug that into branc

[ebon olive]

ok so far i maanged to make it print a string! thanks, im getting there. but when i goes speed, it didnt boost, it just remain the same. so it got something to do with it

[modern radish]

Even if the loop is slow, iterating over hundreds of assets?

[gentle urchin]

All in the same frame, unless something is latent

Like Delay / async load etc

[lunar sleet]

Can’t use a delay in a loop because of that reason

[gentle urchin]

You can delay a loop tho

You just gotta manipulate the default implementation

[torpid juniper]

Is there a special way to create/add a component to an actor in runtime using blueprints?
Also, i have created a bp actorComponent but when in a blueprint i have a variable on actorcomponent, i can't find it to reference. Either by class or by object

Also, with inheritence. If i have a Primary Dataasset of Type Item and then a child of furniture and then child called TestGame. And in Furniture and TestGame i implement an interface. If i call cast to interface on that dataasset as an object. Will it go to the TestGame implementation of the interface?

[torpid juniper]

Tried that but didn't seem to work for me

[thin panther]

Define "didn't work"... Because that is how you do it

[torpid juniper]

As in i have a variable of type object and i passed in an actor component, i did cast to actor component then get class and passed it to that and it failed

[thin panther]

Show the code

[torpid juniper]

Just trying to rewrite it to make it clearer

[thin panther]

Sounds good!

[torpid juniper]

That seems to have gotten it working

I think my code was probs getting mixed up between variables as i had them too similarly named

ty

[lapis imp]

Question if you can help:

I currently have my line trace set up as shown below.

It's making my gun fire vfx go in the wrong direction client perspective; however, the damage logic works fine: https://streamable.com/xjafuz

Any tips on fixing the gun firing wrong way from other player's perspective?

[lunar sleet]

#multiplayer is a whole different beast

[lapis imp]

Ty, I moved msg there

[rose gull]

hey guys, i have used this custom buoyancy component to make a ship that floats. now i spawn an actor on the top of it and want to move it around on the ship. unfortunately when i attach the actor to the ship and keep it relative the actor doesnt move, when i dont attach and the character actually moves on the ship, it impacts the ships movement. do you guys know how i can work around this

[dry bramble]

Sup guys how can I use the gyroscope of an iPhone to steer a car wheel? I already have it ready and working for Android but it doesn't work in ios

[grizzled sparrow]

there's a way to make a projectile go to where the cursor is?

and...also how do I make the cursor visible in game?

[dark drum]

Get the player controller and enable show cursor. If you want to show it all the time you can enable it directly in your player controller in the editor.

[grizzled sparrow]

oh, thanks

even if I already looked up elsewhere

now is the first part the issue

want me to go in vc to show it?

[static shell]

does anyone know what "get player character" has in way of performance cost? is it the same as casting? is it worth while promoting it to a variable?

[dark drum]

Generally you would spawn a projectile and give it some velocity. Are you wanting it to move in the direction of the cursor when it's fired?

[grizzled sparrow]

yes

this is the mess of the code I did for it

[frosty berry]

I have a vehicle that can turn, rotate, etc. and travel forward. I have some "following" ojbects that I want to stay in the same horizontal plane a certain distance back and have them keep that distance as the main vehicle moves forward. The plain is the red line. What would be the best way to approach this?

[grizzled sparrow]

the projectile consistently shoots on the right and super above

[dark drum]

Get player character is fine. I'm not aware of any performance related increases from using it. If you need to cast to a specific character type, it would be worth storing a ref if you need to get it a lot.

[tight pollen]

how can i convert this: "text
text
text
text" to this: "text text text text"

in bp

[dark drum]

Replace node I believe.

[dark drum]

What happens if you plug the whole rotator from the find look at node instead of just the pitch?

[grizzled sparrow]

uh, I left some context out

I'm making a side scroller

[cyan drum]

Can you not just use 'GetForwardVector' on the camera?

[dark drum]

You'll probably still need yaw unless you want it to only ever shoot in one direction.

[grizzled sparrow]

uh, that would make it shoot to the camera

[dark drum]

The get hit result under cursor does a trace into the world and returns the location of where it hits something.

[grizzled sparrow]

still doesn't work

like

I face left, my mouse is at the left

it still shoots at the right

[grizzled sparrow]

why don't we just go to vc?

so I can show it

[dark drum]

Swap the start and target around.

[grizzled sparrow]

nothing

can we just use another method?

[tight pollen]

how

[grizzled sparrow]

maybe using the mouse X/Y axis?

[dark drum]

Well assuming the projectile travels at its forward vector, getting the look at direction is all you need.

Print the location it's giving you under the cursor to see if it makes sense.

[grizzled sparrow]

I'll do it another time

[ionic palm]

Hi guys I was wondering what's the best way to ensure only one tick of damage on a spherecast for melee?

Basically, each sphere trace applies its own instance of damage. For some reason, I can't seem to add a re-triggerable delay into this function either which was my first guess. This is an issue for both my enemy and player as they use the same logic

https://streamable.com/kem9zo

[lunar sleet]

Prly cause it’s a sphere trace

[ionic palm]

Thanks?

[lunar sleet]

Print the out hit hit actor

Also, what’s calling this function @ionic palm

[ionic palm]

Its on my AI tree it is being called I will send a screen

[lunar sleet]

If that hit function is called from inside the attack player task, I could see it going through it again within 1s

Try increasing the wait

[ionic palm]

Ok I will give it a go

[lapis imp]

Produces same issue

[junior prairie]

I'm trying work with the nav link proxy smart links to get my enemy type to jump up on to a ramp, and it's just barely able to land on the edge when jumping up, but gets stuck when jumping down:

the nav link proxy bp looks like this
and it just uses an interface on the enemy bp

which looks like this

[lapis imp]

What you can do is, have a gate that closes after 1 loop.

Once the sphere collision no longer overlaps, it can reset the gate 👍

[ionic palm]

Thanks for the suggestion Rico I will try this out!

[ionic palm]

I am not sure how to implement this into my BP, I have never used this node before I understand what you mean but I am not sure how to and where to plug it in here

[lapis imp]

Imma guess the logic order since I'm assuming you have an overlap event triggering the hit detect

For Gate node, have the logic start at Enter

On exit, have the rest of your git logic there. At end of logic, circle back and Close it.

That way it closes with just once execution

You can reopen it once character attacks again or when overlap ends. This could be done with an event ot something

[lunar sleet]

He’s using a sphere trace not an overlap

[lunar sleet]

What’s in your attack task, and did changing the wait do anything?

[ionic palm]

The logic is triggered by an animation event

The animation is triggered by the AI behaviour tree.

The animation event triggers the logic in for the sphere trace

[lunar sleet]

Idk much about animation but does receive notify tick fire on tick or just once after it’s received a notify

[ionic palm]

I'm not sure tbh

I know it is open for the duration of the animation notify

[frosty heron]

There is begin notify and end notify

for Anim Notify State

there is also tick inside the Anim Notify State

[visual crest]

How do I spawn a static mesh at run time? I was using a Instance static mesh but I can't get it to react with physics right because a ISM can not simulat physics any more

[frosty heron]

if u don't want a component u can just Spawn Static mesh actor

or if u want to go with the component route

select your add static mesh component node and change the variable from the detail panel

[lunar sleet]

He’s using Receive Notify Tick

How often does that fire

[ionic palm]

I commented on your video the other day asking about the parry mechanics your project is really cool man!

I dont suppose you have a system in your game for applying one tick of damage per swing?

I am struggling to apply consistent damage per attack as it applies damage with every new sphere-trace

https://streamable.com/kem9zo

[frosty heron]

I dunnoe, every frame I guess. He can print string and find out

[ionic palm]

I'll try this

[visual crest]

I am trying to add a static mesh for each item in a stack along the spline the ISM worked but it just falls through the floor when its parent has its simeulat physics active. Wich method would be best?

[ionic palm]

It does seem to be applying every tick

[lunar sleet]

Well then you’ve found your issue

You’re sphere tracing every tick

If only I had mentioned testing for this earlier 🙃 #blueprint message

[frosty heron]

I never work with spline and I am not sure what your end goal is. I only know how to spawn the static mesh.
You can hack your way with spawning an actor/object that Spawn the instanced static mesh, that way the owner is not set to your actor that have Physic enabled

[visual crest]

for that, I would likely add an equipped item that causes damage every tic and add time to it every time the sphere trace hits

[ionic palm]

I want to sphere trace every tick to ensure I reliably hit the character.

What I want is to limit the amount of times the damage can be applied during the attack window

[lunar sleet]

Then use a Do Once

On the damage part

[ionic palm]

That make sit literally do it once and it doesnt refresh

[lunar sleet]

Reset when animation ends or w/e

No, let it sphere trace constantly, just do once for the actual damage

Not ideal to be using that many sphere traces but if it works…

[ionic palm]

I tried this initially but it doesn't work at least how I ahve it setup

https://streamable.com/4mp2sp

[lunar sleet]

What doesn’t work? And what’s printing hello?

[visual crest]

So when actor is hit you would check if act has damage item equiped, if not equip one on him. If so check a integeron the item for how long it last until it unequips then if below a set amount add time.

[ionic palm]

Well no damage is being applied at all and the print is from checking the notify tick

[lunar sleet]

Bro your damage is set to 0

Connect all the things

Connect the reset

Fix the damage

[ionic palm]

Literally never touched it while I have been tinkering I have no idea how that changed

[ionic palm]

Connect reset to what?

[lunar sleet]

Prly end of animation notify. Basically whenever you want it to start working again. Also your apply damage should prly be after it, else we’ll just keep going in circles

[ionic palm]

I understand what you mean spawn the set damage item on player but how would I know what damage to apply based on what hit him?

[visual crest]

O my bad I thought you wanted a damage over time effect like a fire burn. You want a only hit once thas easy you just add the actor hit to an array and every hit checks that array if the actor all ready exists it ignores the target. then every swing you just clear your array

Do you understand?

[ionic palm]

I think so I am still unsure how to set it up though.

I need to get the out hit as a variable which I have done

Then I make an array of actors to ignore.

But I am unsure how to convert these into the function you have shown me

For example your function allows you to reference and plug in the LastHit actor but I can't seem to replicate that if I make my own function

[visual crest]

"on trace hit" is your "last hit" variable.

just dif name

you then make an array of the actors hit

then when applying damage you check if that actor has already been added if so don't do damage

then at the end of the animation, you clear your array using an anim notify

Actually looking back at my work I just remembered that actors to ignore would be the ones you hit

[short ivy]

whats the node to get the pawn of a player controller?

[frosty heron]

Get Controlled pawn

[modern radish]

any easy way to convert a collapsed graph into a function?

[lunar sleet]

What’s a collapsed graph

[modern radish]

I see if I right click there's an option to promote to function, will that turn all variables into local variables?

[lofty rapids]

undo: ctrl-z ftw

[lunar sleet]

I don’t think it’ll force them local

[grim sand]

No, if you created them in the event graph, then they will stay as variables available throughout the bp

[visual crest]

you are also going to want three or four sub-traces like this so your weapon does not just straight through the target with
out hitting it

[modern radish]

Cool thanks, then I will recreate it as a function

[lunar sleet]

Ctrl+Z for undies 🙃

[grim sand]

Yea if you want to be extra safe, you can always uncollapse the graph and then select everything to promote it to a function

sometimes UE doesn't like it when we try to skip steps in the 'intended' user flow

[lunar sleet]

I would hope that if they added a promote to function on it, it would work properly 😅

[grim sand]

haha, I would hope so too, but you never know

everything in my brain is screaming that this is a bad idea, is it?

[lunar sleet]

I mean nothing’s plugged in so…

[grim sand]

Haha, yea, didn't want to waste any time in case this is inherently bad practice

[frosty heron]

what's the context?

[lunar sleet]

It’s not usually ideal, but what are you going for?

[frosty heron]

nested loop are necessary sometime

Man I spend whole week making my bp pretty, now I am destroying all of them because of refactoring

[lofty rapids]

you could have an array of strings that you turn into an array, and want to forEach over

[lunar sleet]

Haha refactoring is life, we can only embrace it

[lofty rapids]

since theres no 2d array right ?

[lunar sleet]

It entirely depends on the context

[frosty heron]

I didn't plan to do it but I noticed I had to move all the BP stuff into the base C++ class 😦

[lunar sleet]

How come

[frosty heron]

not planning through

[lunar sleet]

Is it too slow in bp?

[frosty heron]

Nah, just inheritance problem

[short ivy]

this is getting called each time a player joins or leaves. It adds a player arrow for each player. The problem is that is local player controlled kinda only checks if it's you who joined. So when a different person joins for example my minimap gets updated (and adds 2 arrows although it shouldn't add mine) and the one who joined doesn't get arrows added on his minimap at all. Now i am asking here because i think the "Is local player controller" node is wrong

[lunar sleet]

You can usually just make an extra parent

[lunar sleet]

These questions are best asked in #multiplayer

[frosty heron]

prob should have thought about it

[grim sand]

Alright, so I have an array of vectors the tower can fire an arrow from (separate physics actor). However, I need to check from each one of those if they can reach any of the units that are within attacking range (as in the flight path of the arrow isn't blocked by anything). I save the indexes of the units that are indeed in attack range and can be reached from any one of the arrow firing locations.

I can't think of any other way to run through each arrow firing location, and check for all the units that are in range

[short ivy]

but it could be a node problem

[frosty heron]

Sound like a slow operation if you do it in bp but I can't really tell

[lunar sleet]

Everything in blueprints is a node, but #multiplayer is a whole other beast with different rules.

[grim sand]

Gotcha, but perhaps this means then that I should indeed make it a nested loop?

[frosty heron]

my brain isn't working and I don't think I can give u advice on this matter, maybe Neo can 🙂

[lunar sleet]

I’m thinking hard 😀

[grim sand]

No worries, thanks mate.

I might just have to rework the system so that every tower arrow module only has 1 point it can shoot from? That might simplify the system a bit

[frosty heron]

So the tower have multiple shooting point?

[grim sand]

Yea

[frosty heron]

and how are you calculating if the tower can shoot

[grim sand]

Im using capsule instead of line to account for the arrow mesh thickness

[lunar sleet]

Yeah I mean if you need to make another array, on the first loop add unique to a NewArray and then loop over that one on completed

No need to nest

[pulsar pulsar]

So i'm having a little issue where i'm having a very hard time swapping slots when drag dropping in my inventory. I'm setting OriginalWidgetIndex when Drag is detected, i get the widgets index from the UGP and then I set it into a holding variable but when i then try to apply this variable it always manages to set back to 0. I've done prints and I can see that the holding variable is indeed getting set to whatever new slot i'm hovering over with the drag drop content but for some reason when I drop it, the second item always defaults to 0...

[lunar sleet]

Best to ask #umg when it comes to widgets

[pulsar pulsar]

fair

[frosty heron]

is Autheur gone? 😦

need our UMG specialist

[grim sand]

This is a good suggestion. Im gonna refactor the system anyway though, I can only see more and more issues down the line if I continue to make it this complicated. Thanks for the help @lunar sleet @frosty heron

[lunar sleet]

He has been for a while now, might be taking a break

[frosty heron]

u can do it in bp first till it work

prototype is faster in bp

u won't get performance hit unless u hvae many many towers imo

[lunar sleet]

Yeah, should be fine.

[grim sand]

It will stay in bp either way, because I am putting off learning C++ 🫠

[frosty heron]

Don't be, what's not exposed to blueprint you need to code it your self

even just tiny bit can help you long way

[silent drift]

Not sure of this belongs here somewhere else but I have a question about how to save certain player data that I can import to the engine and see how the the player played. For Unity when I was using it I saved the data into a JSON.

I saved the player position once every second to be able to see how they moved.
I saved the death position

This JSON the user could then agree to upload to me (or not) and I would be able to import this into the correct level (the file name said which level it was from) and it would create a white sphere for each player movement position and a red sphere for each death that I then could see in the level.

Would it be possible to do something like this for Unreal?

[fiery swallow]

it's not that this is bad practice, people do loops inside of loops all the time, it's just slow af in blueprints 😮‍💨
you could add a loop w/ delay to the first loop, and then loop through the second one in a single frame

[frosty heron]

Im using character generation and I need to rename all of the material slot in the editor.
If I don't know some cpp, i would have to re-name every slot hundreds of times.
Using utility editor widget and a tiny bit of code saves me hours/days in the end

My old Project in Unreal 4, I do everything in bp, all hard reference, more than 100 NPC. It's tanking at 144 fps 🙂

In unreal Engine 5, with 2 NPC, Im already hitting 90 fps withotu lumen

there are things that I would worry about more than slow bp

[grim sand]

Right check, not sure if I understand what you mean with loop w/delay. Won't the forloop just hit the delay node x number of times, with the delay node only firing once at the first index?

[fiery swallow]

custom foreach loop

[grim sand]

Yea I really need to be learning it. Tomorrow I shall learn 😄

[jade lintel]

yea

[lunar sleet]

Ik there’s JSON nodes in UE iirc

[jade lintel]

they suck tho

use varest

[lunar sleet]

Ah that’s what I couldn’t rmbr

[jade lintel]

i had to rewrite all my json and api call code because the beta plugins were unstable while packaging (what a shocker)

[silent drift]

Ah. Cool. Thanks I will use varest and look into how I can make something similar. 🙂

[grim sand]

Ah right, I will look into this, thanks!

[jade lintel]

best of luck!

[silent drift]

I think the import will be harder than the saving, based on this. :

[jade lintel]

it should be pretty straight forward

[fiery swallow]

https://gyazo.com/a00002268046d18ff0886b85506a39e9
Made a quick video to show you how to do it

0.0 would be essentially waiting one frame

[grim sand]

That is super kind and very helpful, I was definitely struggling trying to understand how it would potentially work

[fiery swallow]

so the first loop would have a delay, the second loop would not (it would just be the default foreach loop)

[silent drift]

Thanks!

[fiery swallow]

for sure man, don't be afraid to customize the nodes UE provides, you can do a lot with them

just don't edit them directly

[modern radish]

thanks mate. I'm trying it now, but is it impossible to have Custom Events inside functions?

[grim sand]

and is it guaranteed for a forloop to finish running through its array within one frame? Or is this only a concern when dealing with very large arrays? In my case the max number of entries would be 61 at any point

[modern radish]

I'm trying to use VaRest to Call URL

and it requires a Callback

[grim sand]

It is indeed. There is a fancy word as to why that is, something to do with functions always returning a result within the frame they were called in

[thin panther]

It is guaranteed. The thread is blocked until completion. BP will crash at more than 1k iterations though

[grim sand]

Gotcha, this is all really helpful

[modern radish]

Is there a workaround for this?

[thin panther]

You can increase this amount, but it's generally not reccomended. Even 1k iterations is slow

[fiery swallow]

if you use the delay loop, it won't crash but I wouldn't recommend looping on 0.0 delay all day

[grim sand]

Awesome, thanks for letting me know, I definitely will keep this in mind and ensure that I never enter a scenario where I am running through that many iterations

[thin panther]

If you are ever at that point, you're at the stage where you might want to pick up a little utility c++ :)

[fiery swallow]

it'll be fine when you get into cpp, Pretty sure you can loop through like 10k just fine

he's beating me to everything lmao

[grim sand]

You will probably need to split up your functionality into multiple functions to do what you are trying. As far as I know functions need to have very specific purposes to make sure they remain optimized and useable. If you just want to keep your bp readable a collapsed graph is probably easier

[remote meteor]

and in extreme cases, you can multi thread the operation so it doesnt block the game thread if thats viable

[thin panther]

Hell even 100k loops are perfectly doable. And depending on what you do you have access to threads.

If threads aren't an option you always have the option to frame slice. I.e. split the loop across frames.

[grim sand]

Any recommendations on good resources for basic UE C++? I find that some resources dive very deep very quickly, which makes it difficult to keep following along

[modern radish]

The problem is that I would like to use the same functionality to read from multiple URLs, then the processing logic thereafter is the same

[jade lintel]

what are you trying to achieve here

[modern radish]

I guess I will do that part in the Event Graph

[thin panther]

Honestly, just learncpp.com and the source code to the engine

[modern radish]

It's a function, and I can't use a custom event apparently

[thin panther]

Once you can understand c++ it's fairly trivial to use unreals api

[jade lintel]

are you making a function for a http request?

[fiery swallow]

https://youtu.be/6485d5Zoc_k other then learncpp.com This video is insanely good for people who already understand code from blueprints

[thin panther]

BP nodes are nearly always 1:1 and can be easily looked up in the source code, and more complex functionality can nearly always be spotted in the engine

[modern radish]

It's a node in the VaRest plugin, Call URL

[thin panther]

You just need that little kickstart of knowing regular c++

[remote meteor]

you can use Create Event and point to a event or function

[modern radish]

Not inside a function

[remote meteor]

with the same signature ofcourse

[jade lintel]

Avoid using call url

use apply url or similar instead

[remote meteor]

Create Event, not Custom Event

[grim sand]

You people are awesome @fiery swallow @thin panther Literally going out of your way to help me get much better 🙏

[modern radish]

Oh that's interesting!

[midnight tree]

am i allowed to ask questions about an error here ?

[jade lintel]

yup

[modern radish]

But seems to be Latent, I cant use inside a function

[jade lintel]

This covers pretty much everything you might need for a http request

[modern radish]

can you run that inside a function?

[jade lintel]

this is in a macro

[sand slate]

Hey I try to load a level and open it when its loaded. I have this two nodes behind eachother, does this make any sense or am I doing it wrong?

[jade lintel]

let me check if its function compatible

[remote meteor]

no its not function compatible because of the latent ApplyURL

[modern radish]

Got it.. I think I need a function because I would like to reuse the logic and read from multiple URLs

[remote meteor]

just use create event to handle the Callback

[jade lintel]

Just make a macro library

[modern radish]

I tried creating event to handle it inside a function, but got error

[jade lintel]

functions dont support latent actions

[modern radish]

But Call URL is not latent.. why is Apply URl better?

[midnight tree]

well actually i am getting an error i am pretty sure but i dont see it bc i made an day and night cycle via tutorial i am pretty new to all of this but it used to work i followed every step checked everthing what i could have done wrong but i cant seem to find it, its that the cycle doesnt move anymore anyone who knows about that stuff?

[remote meteor]

i dont have varest with me but this is the one im talking about @modern radish

[modern radish]

I got it, but then should I make a Custom Event?

[jade lintel]

i'll be honest i dont know

[modern radish]

Create Matching Event? It doesn't seem to work inside a function

[jade lintel]

i read that while scouring the forum

[frosty heron]

You can select create matching function/event

[modern radish]

It errors

[frosty heron]

the event don't need to be inside a function

[remote meteor]

copy that event to an event graph

[modern radish]

But then I need to pipe in two Exec nodes, seems weird

[frosty heron]

Do you not have any dispatcher or callbacks in your project?

[modern radish]

well the Call URL node is inside the function, then I make a custom event for the callback, then I need to pipe the exec again into the function to continue the logic?

[remote meteor]

you cannot do that

the callback with be a separate exec

ideally if you can just move the rest of the execution to the event graph

you cannot continue a latent in a function, functions are immediate

thats the whole restriction of no latent in a function in the first place

[modern radish]

Indeed. I will have to resstructure things

[frosty heron]

I mean it's kinda obvious tho, think of callbacks like "DownloadComplete", "UrlLoaded" etc

[remote meteor]

must you use a function in the first place?
if not, if you can make some flow control to make sure calling the latent, more than once before one is completed, that you would handle it properly

[frosty heron]

you want to only run your Downloaded Logic after download is complete

[remote meteor]

they can just be in event graph

[modern radish]

I would like to use a function because I will reuse the same logic multiple times, after reading multiple URLs

[jade lintel]

macros might help ya

[modern radish]

how about local variables

[jade lintel]

you can also try using "Process URL"

you can use that within a function

[modern radish]

but that doesn't return a JSON object?

[remote meteor]

my way of doing it is to have a varest request object so i can separate the instances to their correct callback functions

the other way is what devboi suggested, by macros

[modern radish]

Sounds interesting, can you elaborate a bit?

[remote meteor]

when it comes to api calls, whether if you want your calls to run in parallel when multiple of them are called or not
i have a helper to make varest request object and stored in a separate custom object for each call, if there are any necessary data needed when the callback is done, it is also placed in the request object. whether the request should block the game(shows a loading screen), cancellable or not, maximum concurrent request, are also defined in this helper. when the request is done, the callback is fired to the function/event we assigned during the construction of the object, ofcourse, with the custom object as the parameter

[modern radish]

Sounds a lot like some of the things I would need as well

[remote meteor]

basically i made a wrapper around the original varest request object that handles abit more data

[modern radish]

and are you using Call URL for your needs?

[remote meteor]

any of the function are okay, i did not use call url, since i have the object, i bind the appropriate delegate, and just the apply url without the latent (i forgot the name)

[modern radish]

Thanks so much for the info mate, I'm only beginning to use VaRest so still trying to wrap my head around how it works. But how do you have the object prior to calling it/reading from the url?

or you mean the Contruct Json Object?

[remote meteor]

let me see if i can still open the project..

basically, if i need a request, i construct the wrapper i made

[ionic palm]

I get what you mean but I can't figure out for the life of me how you set it up

Like I mentioned earlier I promoted the hit variable and made an array but I am none the wiser as to how to make the function

[modern radish]

Okay yeah, I think I understand what you mean.. I'm also replacing the Call URL I had, seems to work with Process URL

[remote meteor]

bind before calling the process

process should be the last

i need to reinstall 4.24 to check

i forgot the name of the function

[modern radish]

but that what I did worked 😄

[remote meteor]

just incase 😅

best practice is to bind first

before calling anything that possibly will do the callback

[modern radish]

like this? but will this work?

seems wrong lol

[frosty heron]

seems right

the previous one look wrong

u just got lucky that it took some time

had the process been faster, u wont get any callback because u bind after

[remote meteor]

connect the request object to the process url

😅

[modern radish]

got it

[remote meteor]

thats a macro..?

[modern radish]

it's just inside collapsed graph

[remote meteor]

ah okay okay

😅

[modern radish]

but that's the thing, I wanted to make a function, so that I can ask multiple URLs

or maybe a macro then

[signal perch]

I’d like to pause the game when it’s not in focus by the player. For example alt-tabbing or minimizing would trigger a function that stops the time until the window is back in focus.

How can this be achieved, preferably in BP? I can’t find a function that returns if window is in focus or not. Best idea I have is to have a transparent widget cover the screen and check if that is in focus. Any advice?

[modern radish]

let me know if you can find it, would be really interested to study it!

[remote meteor]

https://blueprintue.com/blueprint/t8pnwyy_/

blueprint ue dint show it properly, the function signature should be like this

an example if you need to insert a highscore to the api

[lofty rapids]

so your adding to the array in a function, and using it another ? did you run the first function to populate the array ?

or it's working ?

[heavy linden]

Hey @jagged cipher im sorry to bother you but can i ask how you where planning to make spells work because i cant figure it out :')

[ionic palm]

Not quite,

I tried to simplify it for my own purposes as it was spread over like 4 different BP's/AI Tree's so now it works like this first is the Behaviour Tree

Then it moves onto the Attack Player Task, in this task I set the Attacking bool to true

Then it plays the attack player function where it plays the animation and once it is finished it sets Attacking to false

Then hit react is called by the animation event

Then in hit react I have my hit actor added to actors to ignore after the first application of damage. Then it checks if attacking is false before removing the hit actor from the Actors to ignore array.

I feel like I have over complicated this but I also feel like I am close now as it only applies one tick of damage it just isn't resetting as I expected

https://streamable.com/xwbh5r

I missed the attack player function screen

[tight pollen]

how can I add Array to Map variable? only for each loop?

i want convert 2 arrays to Map

i have Keys and Values

[fiery swallow]

@tight pollen I want to help but I can't really understand what you're asking. You only finished what seemed like 2 out of 4 sentences.

if you have an array of keys, and another array of values then yes you would need to use a for each loop

[tight pollen]

poor in terms of performance :/

[fiery swallow]

Assuming your indexes were lined up correctly between "Keys" array and "Values" array you could do this

https://i.gyazo.com/7f9d37e9960e7142516db2c3dab82747.png

Although I'm not sure why you would want to do this, it doesn't really serve any kind of purpose

[ionic palm]

Can anyone recommend a tutorial series or blog post etc. about setting up melee with one instance of damage like I am looking for ?

Basically I want each landed hit to do an allocated amount of damage and eventually stamina drain. All the tutorials I have found show you how to do sphere trace for objects but it normally stops there.

ATM I can only get them to apply damage for every sphere trace hit per swing or do one instance of damage and being unable to reset this effectively after the attack.

[tight pollen]

The Map variable is not replicated and I need to send this data to the server

[fiery swallow]

figured it had to be for replication

well there ya go

[lunar sleet]

Did you fix your values and connect your reset pin yet?

[ionic palm]

Look at my last post I laid it all out what I have changed and exactly how it flows now in my logic its not far if you scroll up

[lunar sleet]

Why are you setting the hit actor and adding to the ignore array twice

[ionic palm]

I'm not, unless I am mistaken it adds the hit actor to the ignore array if attacking is true and removes it if its false

Add > Branch > Remove?

[lunar sleet]

You’re not adding it twice mb, you’re just setting it twice tho

You already have it set, so just use get

[ionic palm]

True I will do that but I dont think it will change the logic

[lunar sleet]

No, just makes it less confusing 🙂

Far as I can tell you went back to running this on tick

With no do once or gate, so running multiple times I imagine?

Tho that branch should make a decent gate

Where are you setting the bool to True tho

And back to False

[ionic palm]

I am still confused by the do once and the gate the examples I found online for do once aren't clear on how to reset it which is why I tried this more primitive method

[lunar sleet]

Ok, forget those then

Let’s just do branch

[ionic palm]

It is set to true before anim and false after anim

[lunar sleet]

So what happens

[ionic palm]

I get hit once for one tick of damage as intended but then it never resets and does no damage after that

[ionic palm]

https://streamable.com/xwbh5r

[gentle urchin]

Hopefully you send it from the server

[lunar sleet]

Put a breakpoint on that branch. Run the game. When it drops, hover over your Attacking bool to check its value, then resume game, see if it drops again. If it does, check the bool again

[gentle urchin]

Maps are O(1) in lookup 😄 arrays are O(n)

[ionic palm]

It triggers once and then never again when watching the simulation but the AI tree is cycling through Chasing>AttackPlayer>Wait so that should include ressetting the variable to true when the next attack player task is called

[fiery swallow]

wait I'm confused, wdym by that

[gentle urchin]

Maps are superior for lookups

When you have the key

[lunar sleet]

Move the breakpoint to the first node in the function or the function call node and see if it’s ever being called again

[lunar sleet]

O = worst case scenario Omega = best case

[fiery swallow]

oh really? I see, didn't know that but does make sense

[faint pasture]

how big is your map?

[gentle urchin]

Biggest

[fiery swallow]

Guessing it's due to not having to loop through the entire thing to find the value?

[faint pasture]

I don't know for sure but I'd bet you'd have to have over 20-30 elements before a map got faster than an array

[fiery swallow]

Figured it'd be relatively the same thing

[gentle urchin]

Iirc maps were im general faster to iterate than arrays

Weird as it sounds

[faint pasture]

well yeah at large N

[ionic palm]

Basically it gets to here after the first cycle and stops working which infers that my character is not being removed from the ignore array I believe after the first cycle

[fiery swallow]

gotta do some research on that, I have a pretty massive array I'm looping through a lot so maybe it's worth converting

[gentle urchin]

Doesnt make sense to me 😅

Iteration should be iteration?

[faint pasture]

oh for iteration I'm not sure

I can't think of how it'd be faster

[lunar sleet]

Sry, big O is the worst case, Omega is the best case. Runtime complexity stuff can be a bit confusing but it’s useful to know when to use a certain algorithm based on the amount of iterations it’ll have to do for example

[gentle urchin]

Its been a while since i tested but i vaguely recall like 30% increase

Dont quote me on it tho

[fiery swallow]

I'm literally trying to get to the bottom of this right now

[lunar sleet]

Actually, that likely infers your cast failed. Put a print string on that cast failed pin to test

[fiery swallow]

I'm like a crack addict when someone tells me about iteration gains

[modern radish]

Thanks a lot mate, I will try and have a look!

[modern radish]

the thing is that I only ever want to read values, and not send anything over to the URL

[fiery swallow]

Our game suffers from iterations loops the most

[gentle urchin]

I ended with TQueue

[fiery swallow]

delays come second

[ionic palm]

Yeah you are right it is failing but isn't it failing because my actor is being ignored?

They aren't missing me I can see the sphere trace go through my character after the first cycle of damage

[lunar sleet]

It means whatever your sphere caught is not that actor. Print the hit actor to find out what it catches

[faint pasture]

I'm bout to test array set and map

[ionic palm]

Do you mean like this?

If so it's not printing anything

[fiery swallow]

Spill the results pls

[gentle urchin]

spill the beans.. or else

||https://tenor.com/view/yoda-gif-25697311||

[fiery swallow]

TQueue? I'm learning a lot today

[lunar sleet]

Connect the actual execution pin first

[ionic palm]

To what? Wont disconnecting anything break the chain?

[lunar sleet]

In between lol

[gentle urchin]

yeah it tries to avoid unnessesary memory allocations

so it's a circular buffer

[ionic palm]

Simpleton moment mb haha

[ionic palm]

1st hit is my pirate 2nd is nothing

[fiery swallow]

Is that faster then findbypredicate? I heard in some situations that could be fasted then iterating... but again I don't get how. Seems like just an extra step

[gentle urchin]

It's not ment for finding anything

[lunar sleet]

Yeah, so 2nd hit is not detecting it…. lol I just rmbred you’re adding that actor to the ignore array…for some reason

[fiery swallow]

Hmm 🤔 time to look up some documentation

[ionic palm]

I add my character to the ignore array after the first hit it's then set to remove it from the ignore array once the attacking boolean switches to false

So that it applies one tick of damage and then shouldn't be able to apply another until the next attack as the actor should only be removed from ignore after the animation has finished

[gentle urchin]

I use it to compose a list of all the 'workers' that have requested something from the manager
from there i Dequeue however many i process that tick

[lunar sleet]

You shouldn’t need it at all. If Attacking is set to True properly, it’ll never get that far

[ionic palm]

I'm not sure what you mean, if I add myself to the ignore array surely I have to remove myself at somepoint if I wanna be able to take damage again?

[lunar sleet]

I mean you shouldn’t need to do any of that

The bool check should be handling the “gating”

But anyways, simple thing to test for, check the value of the ignore array on the 2nd breakpoint hit

If it still contains your actor, you know why your trace is failing

[fiery swallow]

we were planning to do something like this to limit how many inventory actions the server is allowed to process per frame. You might've just helped big with that

[ionic palm]

How can I print the array? or check it in simulation can I just hover over it?

[gentle urchin]

glad to be at service. Ill bill you in the morning

[fiery swallow]

brings me back to "$100.00 an hour starting now"

[lunar sleet]

Just hover.

[ionic palm]

I see my pirate is still in the array

[lunar sleet]

Problem solved, next 🙃

[ionic palm]

But I still don't understand why as the boolean should remove it with the setup no?

[lunar sleet]

Because that should prly happen while attacking is true not false

[ionic palm]

If I switch the branch to true instead of false I have the same issue of damage every tick

[lunar sleet]

Ugh lol

K, let’s make this simpler

[ionic palm]

It feels like it really should not be this hard lol

[lunar sleet]

At the very beginning of your function

Have the branch checking if is attacking

[ionic palm]

Ok

[lunar sleet]

Hang on

[ionic palm]

Here is the full chain.

It seems way too convoluted

[lunar sleet]

Well yeah, #animation is involved. I don’t think using that receive notify tick should be what’s triggering this

Realistically all that should happen is when your attack is called, the animation is played and separately, the trace is made and the damage done

You linking it to the anim’s tick is what’s making it all fire multiple times and having to gate it that way

[ionic palm]

I know what you mean but I dunno how else I could get reliable hits without dumbing down the collision and just using a box volume to do a set amount of damage or something

[lunar sleet]

I’m confused as to what that has to do with it. This isn’t precise anyways because you’re only letting it do this once

It’s not like your trace is doing anything throughout the animation

[lunar sleet]

Aww, not pico ? 🥲

[ionic palm]

https://streamable.com/xwbh5r

Look at the sphere cast it is drawing a line through the air where the attacking arm is.

It only applies damage once yes but at a specific spot on the player and at any point the player appears in the arc of attack.

Without a spherecast what else could I do other than like I say dumb it down to a box collider?

I am just going to have to find a course or tutorial on it as I have ended up with a jumbled mess atm from several tutorials

[fiery swallow]

testing the other 2 things I'm guessing?

[lunar sleet]

Ok I see what you mean

[fiery swallow]

hang on so this is equivalent to just getting "0" from an array and removing it everytime lol

[red berry]

If I am creating a UserWidget, why do I have no option to bind an event to an event, like OnDragCancelled? It seems like I have to create a custom Event Dispatcher in the UW, and then when I create it, I can bind to that custom event. I find myself going:
Event On Drag Cancelled -> Do Stuff -> OnDragCancelled2 (Event Dispatcher) -> Do stuff in parent
Is there a way I can just bind to the event, and not the custom event dispatcher? There's no option to do so

[gentle urchin]

You could do this manually by only resizing the array if the element amount exceeds the count. You'd also have to track the tail and the head

it's probably less efficient that way

[gentle urchin]

20k plz

[fiery swallow]

no I'm pretty sure you create your own event dispatcher for that

the only reason there's default event dispatchers is because they're already declared in the cpp parent widget

[faint pasture]

ok so wtf

Why does array lose at a million

[gentle urchin]

Damn

It had such a lead

[faint pasture]

This is just summing random integers

[gentle urchin]

And then just fell so hard behind

[gentle urchin]

TQueue next?

Then we're done

[faint pasture]

    Accumulator = 0;

I just bought this as its £16 rather than £50 with a fresh Udemy account so hopefully this is more than enough for my needs

[fiery swallow]

this test also takes into considering setting, I was only looking forward to the getting portion

[gentle urchin]

This suggests that my array iteration was not very good tbh

[faint pasture]

no the set isn't timed

the set takes forever, a million random numbers is pretty rough lol

[lunar sleet]

Most tutorials out there are crap, def shouldn’t be spending money on any but up to you

[primal veldt]

can anyone help me setup some simple wall procedural genration, kinda like a maze but more spaced out?, ue5

[gentle urchin]

Resize with random int initializer 😄

[unborn sigil]

Feel like I'm missing something obvious, but why would a blueprint class in my project not be appearing as an option to cast to within a separate object's blueprint?

[lunar sleet]

Bad ref

[fiery swallow]

ah, don't understand why the map took longer and longer each time then if it's O(1)

and why did 1mill make the difference lol

[gentle urchin]

Iteration != lookup

Or find... rather

Iterating an array should be faster as thats just mem displacement

While the tmap has some fancy magic

[fiery swallow]

 for (const auto Element:TestMap)
    {
        Accumulator += Element.Value;
    }

ah yes I'm just an idiot

he's looping

[gentle urchin]

Find in a TMap is far faster than Find in a TArray

[faint pasture]

yeah i'll do finds next

[gentle urchin]

Find in TMap is equal to (or very close to) the same as Get(MyInt) from array

[faint pasture]

it is, at a certain point

hashing isn't free

[gentle urchin]

True

[ionic palm]

I mean where else would I learn lol?

I have exaughsted all of the free content on youtube and searched the docs and my issues on google independantly and asked in forums I feel I have tried everything else haha

[lunar sleet]

Well we were still working on the issue

What happened when you added the branch at the start ?

No breakpoints, just normal run

[ionic palm]

Nothing it just functioned the same.

I appreciate you taking the time but without me just sending you my project and having you dissect it we could be here forever and I wouldn't expect you to waste that much time and effort on it.

I think the issue was me using a rudimentary AI tutorial as a foundation for an increasingly complicated melee system so I think I will be better off going from A-B with a more complex system over 15 hours of content.

[lunar sleet]

I watched an 11h tutorial as my first and most of it was a waste of time and bad code, but I mean give it a shot ig

[ionic palm]

Well same haha

Hopefully, a course not aimed at complete noobs will have more applicable systems for my project needs

[unborn sigil]

I'm not seeing anything abnormal in Reference Viewer though

[lunar sleet]

It wouldn’t show as anything abnormal

Bad ref as in you might have given it the wrong object and searching context sensitive. Show code

[fiery swallow]

the better you get the more challenging problems you'll face and ultimately the less likely you are to find help for it. You should see it as a good thing. We all had to go through that. You'll figure it out so long as you don't give up 🫡

[primal veldt]

can anyone help me setup a procedural wall generation placement method on a plane? basically a spaced out maze of sorts

[fiery swallow]

probably

[primal veldt]

i have to go for the moment can i dm you when im back?

[unborn sigil]

apparently I was foolishly trying to cast from a BP in my main content folder to a BP located in a plugin folder

[fiery swallow]

Respectfully I'm gonna have to decline as there's no gaurantee I'll be able to help you with your problem specifically. What I meant by probably was that if you asked a more detailed question, the community could probably help you reach your goal.

[ionic palm]

Thanks for the encouraging words Moxie!

I understand what you are saying. Unreals so dam straight forward until it isn't I just wish there was a more gradual middle ground haha

[faint pasture]

K so it looks like 10k is your break even point at least with tiny data

[fiery swallow]

thanks for that, some good information

[fringe junco]

I have an inventory system thats currently borked. im certain its the On Preview Key Down Func and the correspondign Refresh Item event call being incorrect but can't sus it out.

[trim matrix]

alright so, im having a problem, where im the text render isnt aligned the way it needs to be and facing the incorrect direction. its suppose to be like in the last image as the last image is the actual blueprint itself? and the middle screenshot is the blueprint as a child of the parent blueprint its in, any ideas on how to fix this?

[oak fable]

hey there
i made a simple ai that moves to a location i gave to hem with one speed like he runs all the way to the location
so i need to adjust the speed based on the distance
i can get the distance but i dont know how to make hem change the speed for when he gets closer to the target

[fiery swallow]

You should be able to have it face the correct way by dragging the text component under the red square's component

[fiery swallow]

Are you trying to decelerate the closer you get to the target?

Essentially coming to a smooth stop?

[oak fable]

yeah

[fiery swallow]

There isn't a simple way to do that, you need a movement system made for that. Or you can try to make some hack on tick or on a timer that changes the characters max walk speed based on the distance of the target

[oak fable]

like run if its more than 200m jog if its less than 200m and walk if its less than 50m

[fiery swallow]

So every 0.1 seconds or every tick check the location between the character and the target, and gradually decrease or increased based on some math formula

[oak fable]

i was thinking about that
i made it but in the move to target function and the issue is it wont work unless i press or give hem new destination

[oak fable]

yeah exactly

[fiery swallow]

Set max walk speed

In the movement component

AI move to respects it at any time

If it's not working you should show your code

[oak fable]

okay let me try

[trim matrix]

what do you mean?

[fiery swallow]

Drag "TextRender" into "RedDoor"

Once you do that it will be like sort of a child of red door and will inherit from it

[trim matrix]

the text iokay i will try that

[fiery swallow]

Then whenever way the red door faces, the text render will be relative to it

[trim matrix]

the thing is, its suppose to change to unlocked and the red door is suppose to dissapear thats alll

[fiery swallow]

That wasn't the initial problem 😅

[trim matrix]

and even tho its inside the red door now, its messed up

[trim matrix]

yea the problem is the text render is messing up with the parent blueprint its inside and i dont know why

[fiery swallow]

Based on your images, it looked like you were changing the rotation of the red door rather then the entire actor

If that's not the case then I don't understand why your text render was facing the wrong direction

[trim matrix]

so this is it in the blueprint, this one is the open-close blueprint (text render looks fine in this screenshot), but in the blueprint Equation (Parent Blueprint) i have the Open-Closed blueprint as a child inside the viewport now the text render is messed up and isnt facing the correct direction or in the right position

which is the problem im facing

[fiery swallow]

Have you checked that the relative rotations are all correct?

[trim matrix]

let me look

[oak fable]

okay i tried this way but this work only if my waypoint is spawned and i do destroy it once i got the location so what should i do

nvm i found i way for it

[trim matrix]

figured it out, turns out a few things werrent hooked up

[oak fable]

okay i have another issue
whenever i hold the move to location key and the waypoint appears if it get near the ai or me it move to the camera location and stuck as the shown in the picture
why is that and how to fix it

[red berry]

Quick question, how do you put a literal enum as a value for a string? I dont want to set a variable, just pass an enum from an enum, into a string
Edit: found it. Literal enum node

[lunar mulch]

I have 2 landing animations where a widget is created and removed when the Landing animation completes. However 1 of the landing codes doesnt properly remove the widget. The codes is nearly identical. Why won't it remove the Widget on the bottom Code? ( i checked with print strings, and it's properly reaching the "Remove from Parent" node.) It's a repost, but at this point i wanna know. (Both codes are using the same widget)

[lunar sleet]

Is this code in separate blueprints?

[lunar mulch]

Nope both inside my character bp

It's so weird, it get's past the remove parent node, and it doesn't give an error. So technically the widget should have been removed. But it stays there.

[lunar sleet]

So both of your hard fall and your soft fall use the same hard land blur widget?

[lunar mulch]

yeah

i copied the code from the working one to be 100% sure nothing iffy is happening :p

[lunar sleet]

Try using another var

Yeah, except in programming copy pasting is usually the wrong approach but regardless

[lunar mulch]

i mean it was original code at first

didn't work, so i copied to double check

What do u mean with using another var?

(Sorry wanna make sure i understand correctly)

[lunar sleet]

Make a soft landing ref instead of reusing it

Like on create widget for the soft landing promote to a new variable and call it soft landing

[lunar mulch]

hmm will give that a try

[lunar sleet]

And on your remove from parent just use get

Once it’s set there’s no need for spaghettios

Cleaner anyways

[lunar mulch]

Bummer, but no bueno :/

Ah well, off to bed. Thanks for trying tho Neo, much appreciated

[uncut vigil]

Does anyone have any good suggestions for limiting the movement of a player controlled camera or spectator pawn to a specified area? Something like a collision box that prevents actors from leaving it instead of the reverse where it prevents anything from overlapping it?

[remote meteor]

the only difference is the GET and PUT request, they are otherwise similar.

[vast kindle]

Hello everyone - by any chance is there any way to send a struct worth of data into the payload of a Gameplay Event?

I am trying to pass a couple different relevant pieces of information over to a gameplay ability but not quite sure how to send it through.

[remote meteor]

there are different ways to do it, optional object as the first, or though a custom EffectContext

ofcourse, the optional object needs to be replicated beforehand for it to work over a networked multiplayer

as for effect context, you can read more about it here https://www.thegames.dev/?p=62

[elder fjord]

Does anyone know what logic Unreal uses to expose pins on blueprint struct nodes? I have a USTRUCT defined in C++ with like ~5 properties, for example, and when I create a "Make FooBarStruct" node in Blueprint, it seems to only display the first 2 pins. Not a big deal, since I can just expand the node, but it seems a bit arbitrary

[vast kindle]

Hmm... challenge of an object is that my values exist atm as a struct variable, I'd assume that the only way to make that viable would be loading it into a component of some sort and passing that as the optional object?

As for custom effect context, this is definitely interesting - but I'd assume it isn't possible to do this with blueprints alone is it?

[remote meteor]

a normal UObject as the payload is fine

custom effect context indeed requires c++

[vast kindle]

How would I get the struct loaded into the UObject to attach, hm..

[remote meteor]

luckily, nowadays we have something called InstanceStruct

you can make an UObject with a property member of InstanceStruct and set within

if the struct doesnt change across different gameplay events, the UObject also can just hold that specific struct instead

[vast kindle]

Instance Struct? Thats a new one

[remote meteor]

InstanceStruct allows a variable to hold any type of struct, however, the code needs to know exactly which struct to break to at the other end when you want to use it (similarly to a getdatatablerow)

making it useful for stuff like "payloads"

[vast kindle]

Hmm, trying to find stuff on it - not having too much luck yet.

[remote meteor]

this variable type

you can make a uobject that contains the variable

you can construct the uobject that contains the payload

[vast kindle]

Hmm... I am not seeing Instanced struct as a variable, nor am I able to get it to pop up when right clicking in the event graph

[remote meteor]

which engine version are you using?

it is only available in UE5 if i remember correctly

[vast kindle]

5.2.1

hadnt moved over to 3 yet

[remote meteor]

none of these? 🤔

[vast kindle]

Hmm... none - is there a plugin I need to enable?

Ah, "Struct Utils" experimental

[remote meteor]

Oh it is a plugin 😅

[vast kindle]

Nice 🙂 - Gotta head to bed, but I'll dig into all of this tomorrow, I think this can help on a lot of things

Thank you again for the help 🙂

[modern radish]

Thanks! But it’s true I might need it later, some sort of leaderboard. How do you handle that, where do you store this info? Some database?

[surreal bridge]

Having a bit of issues with mobile controls.

I have the enhanced input set up to use a click control when the player left clicks but also for touch 1

It works fine on the PC but on mobile the event is never fired

[short phoenix]

In the graph view for a widget blueprint, I am trying to listen for the tab key. The event doesn't seem to come in from there. I see it if I add it in the character controller logic. Is it even possible?

[glossy cloak]

I just came across struct inheritance and my gears are turning... is this available via blueprints/the content browser? Or is this CPP only?

[short phoenix]

I saw I could override key down and work off of that, which means some cross-communication anyways, so I suppose I'll just keep the main logic for the key in the character controller and set up an event for it instead.

[glossy cloak]

You could bind to a dispatcher that gets called on the controller when the player presses Tab

I suggest doing this with a blueprint interface.

Or if you have a direct reference to the widget on your controller/character, then you could just call whatever function you want when it's pressed.

You typically don't want to detect input in widgets since it's input and most input should be handled on the player controller/character

[glossy cloak]

I think tha'ts a cleaner route that will make it easier to debug in the future once you've long forgotten how you set this up. Lol

[short phoenix]

I lost how I had the logic in the character controller (I guess I didn't actually save the blueprint when I committed to git) so I have figure out how I was getting a handle to the widget again

[red berry]

Whats the best way to refactor a specific funcition, thats used in multiple different classes? These classes inherit from different parents, so unless you can inherit multiple parents (which I think you can't in unreal), then inheriting won't work.
Should I just put the function in the GameState and just get GameState and call it? Every object and class can get a reference to GameState

[short phoenix]

How would I plumb the menu widget to the character controller? I'm editing it through the content browser itself versus in the level and I've never assigned a variable that way.

Can that even be done?

[glossy cloak]

Do you mean that you've basically rewritten the same function in multiple classes*?

Why not create a blueprint function libarary and put it in there, then call it from all the classes?

That way you only have to modify it in one place and it can be called from anywhere in the project with no reference to the game state and no casting.

[glossy cloak]

How are you creating the widget and adding it to the screen at runtime?

[short phoenix]

Uhhh I was doing something that apparently never got committed to git so now I can't tell you. :p Previously, I was instantiating the widget in the character controller.

[glossy cloak]

And no. Since widgets and all actors, for that matter, once spawned into the game are individual object instances, you can't set a direct reference to them until they've been spawned.

[short phoenix]

Ok I guess I need a one-time create and work off of that.

I think I got the mechanism back.

[glossy cloak]

Typically on begin play in your controller or character blueprint you'd create a widget, then promote it to a variable so you can then modify it or remove it later in your code.

Or you could do it in the game mode. Wherever makes the most sense, really.

[short phoenix]

Well promoting to a variable is a new one.

[glossy cloak]

If it's a score HUD then it would make more sense to be stored and modified via the game mode. But if it's the character's HUD with health and such, then the character should own it.

[short phoenix]

It's the main menu

[glossy cloak]

Obviously you'd want to create your own widget. I just grabbed a random one from the list since I don't have any widgets in this project yet.

[glossy cloak]

Yeah. Personally I'd spawn that in the game mode, but it's not a big deal if you do it on the controller.

[short phoenix]

Heh I just want it to work once and then I can rearrange the furniture . . . after I properly preserve it in source control this time haha.

[glossy cloak]

Ctrl Shift S is your best friend.

[short phoenix]

But I did the same stupid thing I did the first... five times I've tried to use an interface and made the interface implementation in the blueprint be a call to the interface instead of an event matching the signature.

I thought I had done the save all!

[glossy cloak]

Lol It happens to the best of us.

[short phoenix]

Huh I think I need to add the interface to the widget blueprint but I don't see an interfaces section.

[glossy cloak]

What's the interface for?

[short phoenix]

Toggling the main menu GUI. No params. Just a kick. The main menu has the logic since it has a return to game widget inside of it that's dealing with getting out too.

[glossy cloak]

If you have a direct reference to that type of widget (which you do when you promote it from that specific class like you're doing) then you don't need to use an interface if you'd rather not. You can just make a function or a custom event in the widget, then call that from the widget reference you created.

[short phoenix]

Ehhh that's true

But just cuz', how do would I cram that in there? I am just surprised there wasn't a section for it. I'm guessing I can't use an interface?

[glossy cloak]

There is.

Click that, then it'll show up in the details panel in the graph view.

[short phoenix]

Ohh ewww it's not there by default?

[glossy cloak]

It is. You just have to go to the settings.

[short phoenix]

Yeah I saw it and groaned lol

I can't remember if I did that previously but juuust enough time has passed.

[glossy cloak]

Class Defaults are the variables and Class Settings are additional options for each class.

[honest ember]

Hi I have a question.
So I am using a timeline to change some material parameters over time and for some reason the values I am lerping between increase. So I have some waves that move at speed x and I want to change it to y. (x=high speed/y= slower speed). Whe it goes from x to y right before the transition ends the waves start to move backwards like the value would reverse and when it goes from y to x it incresese their speed while transitionig and then they slow down when the timeline ends.
Any idea what could cause this and how I can improve it?
Any advice is appreciated.
Cheers.

[dawn gazelle]

Yep, it would be a database of some sort, the API would just be a means of requesting or sending the data over HTTP.
Just be aware, that if you allow players to host their own servers (whether dedicated or listen) and expect the servers to update your leaderboards, it will be insecure and tamperable, so be prepared that the leaderboards will likely be filled with junk at some point due to malicious players figuring out how to send spoofed requests to your API.

[short phoenix]

@glossy cloak thanks. I'm actually writing that down this time and hoping I don't smack my forehead into that one with interfaces again. I use them all the time with regular old programming but Blueprints puts them here and there and I feel like a kid trying to learn C again by hunting and pecking the crazy function names out of a book.

[glossy cloak]

Can you send a screenshot of what your timeline graph looks like?

[honest ember]

yes it is very simple.

just goes from 0 to 1 over x amount of seconds

right now is set to 10 sec but I also tried with 1 min and I still have the same result

[glossy cloak]

Are you triggering it to reverse at some point?

Try printing the alpha value coming from the timeline to see if it actually goes 0 to 1 or if it goes back down?

I feel like the problem has got to be something to do with triggering/retriggering/reversing the timeline.

Timelines typically just end and then they're done. They don't reset or reverse unless told to, so unless you've got more functionality also lerping these values somewhere else or more functionality modifying the timeline/triggering it, then I have no idea. :/

[honest ember]

I am triggering it by mouse input and using a flip flop to reverse it

[frosty heron]

FlipFlop, delay and timeline

what could go wrong

[honest ember]

idk to be fair as I am new to blueprints

[frosty heron]

It warrants bug at first glace if I can give my 2 cent

[glossy cloak]

Is this UE4?

[honest ember]

yes

4,27 if it matters]

[glossy cloak]

Huh. You're like the third dev I've seen this week using UE4. Plus me! lol

[frosty heron]

My old proj still sitting on UE4

[honest ember]

hahah

[frosty heron]

UE4 100+ npcs, hard reffing everything 144 Fps

UE5 , 2 NPC. capped at 90 Fps without lumen

I dunnoe if it's just me but I'm still struggle to find ways to increase fps

[glossy cloak]

Huh. I was considering upgrading to 5.3 to save performance with Nanite. Guess not. lol

[glossy cloak]

So.

My first guess is the delay on your reverse flip flop.

[frosty heron]

Don't quote me, that's just my personal experience

[glossy cloak]

Does it work the first time you click?

[honest ember]

so the first time I click right before the transition ends the waves move backwards like the value would go from 1 to -1

[glossy cloak]

That delay is definitely going to cause some problems. If you click, then click again, the delay will wait, even if you click again, then trigger the reverse even if the timeline is meant to be going forward at that point.

[honest ember]

when the timeline ends it works properly

[glossy cloak]

Why are you using a delay?

Also is that a 10s delay?

Or a 1.0s delay?

[honest ember]

i used the delay to give a bit of time for some things to dissaper before the transition starts as this is part of a dynamic weather system but I could remove it

[honest ember]

is 3 sec

[frosty heron]

Imo FlipFlop have no place in end product, it's okay to use for prototyping.
Problem with flip flop is that it always remeber the previous state, this make it not scaleable and can cause a lot of issue.
Switch to boolean. In your case you might want to do a check if Changing the weather is commited but not yet completed.
In which pressing the button does nothing until w/e u want to do is completed

Delay shouldn't be used either in this context

[glossy cloak]

Either I'm blind or the screenshot resolution is just awful. lol

I guess I can see the 3 if I'm looking for it. Lol

[frosty heron]

Why do u want the delay?

get rid of it?

cursed as f

because no matter what after 3 seconds it will execute the code after completed

[glossy cloak]

Yeah. If I were you I'd use a gate and reset the gate on complete.

[frosty heron]

When u want to "Toggle" between states, you can use play the timeline and reverse

[honest ember]

i got rid of it

[glossy cloak]

I wouldn't even use a bool, tbh. I'd just add a gate with a custom event to "ResetWeatherGate" or something and then call that on timeline finished.

[honest ember]

so I removed the delay and I still have the same problems

[glossy cloak]

If you do want to use a bool you can use one of these.

[glossy cloak]

Try right clicking on the flip flop node and add a "breakpoint"

[glossy cloak]

Press play and test it. It'll stop your code and bring you to the blueprint. Hit resume in the top menu (green play button)

And see if the flip flop triggers again without a click.

[dawn gazelle]

Does this X to Y transition "reversal" only happen with the water material or all the others too like the clouds?

[glossy cloak]

And does the reversal happen within the time of the timeline, or after it completes?

[honest ember]

on the clouds I don't see any problems

only on the water

[glossy cloak]

Ah. Okay, so it's likely a material issue.

[dawn gazelle]

Then your issue is likely in your water material.

[honest ember]

after it completes

[glossy cloak]

Oh. If it's for sure after it completes then maybe not.

[honest ember]

oh sorry

i missunderstood

so the problem where the waves move backwards happens right before the timeline ends

[glossy cloak]

Okay.

Then yeah, it's an issue in the material.

I like your boolean state setup better though, so it was worth the code review. lol

Maybe make a material instance of your water material and try setting those values manually to see if it performs as expected.

It sounds like when you break a certain value, the material is reversing.

[honest ember]

yes that is what I did and it works properly

after the timeline finshes the material again behaves as expected

I only have that weird state for a sec before the timeline ends

[glossy cloak]

Huh.

[honest ember]

what set-up you mean? the one that Cold Summer sent?

[dawn gazelle]

Like, it could just be a combination of the changes you're using that it ends up appearing like it's moving backwards
Flow Strength, Flow Speed, Flow Density, Flow Panning, Mesh Distortion and whatever else you may have... Combining these things together may give the appearance of moving backwards when changed together and once the timeline is done it can just continue.

Especially since the values would interp at different rates since they're varying values

[honest ember]

this could be possible yes cause I have no way to adjust these manually all at once so I can't really test it

[glossy cloak]

Oh my bad. I thought you posted that. But yeah. There's nothing wrong with a flipflop, but you'll need to gate it if you don't want players spamming the input and causing some weird results.

[dawn gazelle]

You could make a test UI slider that transitions from 0 to 1 and sets those material parameters

Then you can just drag it around and see how the material behaves

[honest ember]

i see. Yeah I will probably change it to what he sent if it is better. I am new just learning blueprints so I don't know what it would be better over a certain thing

[glossy cloak]

Game development is so frustrating. You struggle with an issue for hours and hours only to find out that it's just the result of a visual phenomena that you can't even change without rethinking how you did the entire system.

[honest ember]

the player wouldn't cause any problems cause this system will be tyriggered by another custom event

the mouse innput is for testing

[honest ember]

yeah

[glossy cloak]

You could do something like this to prevent spamming.

I prefer this sort of setup over making a bunch of boolean variables.

[glossy cloak]

Oh I see.

Then yeah. The gate isn't necessary.

But keep in mind that the flip flop might get a bit sketchy if you save states between sessions or change levels or anything like that. Maybe a boolean to determine if it's storming or not would be best. Or whatever this is for exactly.

[honest ember]

i see

thanks for the help

Hello there, i was wondering if anyone could perhaps just inform me the difference between each method of interaction.
One being a cast to a master class and using the interact event on Child Blueprints or a interface.

Just curious if one was more beneficial than another in a general use.

[thin panther]

For interaction you would generally use an interface. Interfaces are for class agnostic functionality. Everything that can be interacted with cannot feasibly share a base class, without horrific to manage inheritance trees.

Since interaction can happen across a range of base classes, that's where an interface steps in

[glacial sierra]

Not sure if this is the right place to ask, but are these modellingtools can be scripted / exposed somewhere? Where do I start to look at it?

if all enabled

now im breaking the forloop when one is false

but its not working

[gentle urchin]

You need to store the result

Since you're breaking

If you wrap it in a function you can do the same branch and simply return false.

And if it completes, return true

[versed sun]

I would try this

Hi!
working on the VR template UE5, I need some help please.
I tried to looks it up but I couldn’t find anything that can help me do this:
Widget with text and/or photos in a trigger box.

I want the virtual player to step into a specific point to see images and information.
** My workflow:

1. Created the UI widget , created the actor (blueprint class) , added widget component and then added my previously made widget.

2. Placed the trigger box and inside it , I placed the actor (now i can see the text on the screen)

3. In the event graph of the actor:
   OnActorBeginOverlap> create widget > add to viewport
   OnActorEndOverlap> get all widgets of class > remove from parent.

I previewed in the VR:
The text is there but it doesn’t appear or disappear, it is just there even when I am out of the trigger box.
What is that I am doing wrong.
Also, if you have some tutorials on that, please refer to it

[steady night]

@versed sun i just noticed since the function dont have a breake and the complete is set to "all enable" wont it always be All Enable ??

[versed sun]

nope, the For each loop will stop and NOT do Complete if you Return in the loop

[steady night]

oh

[tight pollen]

i load Data from save game object in server and send it to clients, but this data is too large and i have this Error: LogNetPartialBunch: Error: Attempted to send bunch exceeding max allowed size. BunchSize=114657, MaximumSize=65536

[versed sun]

So, the loop stops running and it returns on the first False

[steady night]

aye dident know that 😛

s,art

[lunar sleet]

What exactly are you saving that’s so big?

[lunar sleet]

Show the actual code of how you’re adding and removing the widget

[tight pollen]

1000 arrays of string, texts, integers etc

is just big

how can I split an Array into parts?

[lunar sleet]

Make smaller arrays. Strings and texts and ints are not usually that big but sure

[tight pollen]

also i have in this structure Classes, Vectors 2D, another Arrays of string

[sonic meadow]

I unfortunately don’t have access to the laptop until Monday (I work on university devices)
I will send again everything I did w/pics

[lunar sleet]

Yep, just post again on Monday ig. Remove from Parent is the node that removes a widget

[sonic meadow]

Thanks! I will post again on Monday

[tight pollen]

is there a quick way to split an Array of Structure into parts?

[lunar mulch]

Your tip worked, appearently you need to have a seperate variable for evert widget creation 🤷‍♀️ after a week of fiddling finally managed to get that Landing Event solved.

[lunar sleet]

Nice

[steady night]

@versed sunoh right now i se the problem

@versed sun thats true when u said if its false it stops the loop, but thats now working in my case since im checking if Any of the 4x indexes is true

its not looping to the next one since it returned already

so im testing something like this looks fin e ?

[versed sun]

If any are true

[steady night]

oh right thats simpler 😛

[versed sun]

Make them Pure , too

[steady night]

huh

wich ones ?

[versed sun]

the functions, they can be Pure

[steady night]

oh cool

what dose that do :/ ?

oh i can hook it directly into a function

[frosty heron]

read the name 😄

array of widget only

it's checking if all the widget is enabled. You can grab the widgets you placed and add them to the array

[lunar mulch]

I have some code here that slows down movement speed. However, the Variables don't seem to work. It does slow down movement speed, but only for a milisecond and i cannot adjust the duration and how much its reduced. Eventho the code is set up to do that. Any idea what i could have missed?

[tight pollen]

someone give me idea?

[lunar sleet]

Are you changing max walk speed anywhere else?

[frosty heron]

Don't make much sense to me

[frosty heron]

Declare empty array struct, Do a for loop and add the element to the array

though I can hardly see a use case

[lunar sleet]

Apparently he’s saving so much crap it’s throwing him an error

Idk what splitting the array of structs will do for this but 🤷‍♂️

[tight pollen]

I will send smaller Arrays from the server to the client

[lunar sleet]

So this is nothing to do with saves and you’re trying to send a heap of data from server to client, for some reason

[tight pollen]

but of course they will all be loaded only with a slight delay

[lunar sleet]

You need to go ask #multiplayer if what you’re doing is completely wrong

What you’ve described so far sounds like something chatGPT would say

[tight pollen]

this data is displayed in widgets and the widgets are not replicated

so there is no other way to send all the data to the clients

[lunar sleet]

Yeah, you’re probably approaching this wrong tho

Ask the experts in that channel

[tight pollen]

if these were actors, it would be different, the server loads everything and the players, when they are close enough to these actors, are replicated

[lunar sleet]

Server is not supposed to overload clients with data

[echo storm]

How can I access this variable of the Anim BP in my Character BP?

[blissful grail]

Get your skeletal mesh. Get Anim Instance from that. Cast to your ABP. Now you have access to it.

But that isn't the way data should flow. Your ABP reads from your character, not the other way around.

[dark drum]

whats the data?

[lunar sleet]

Ya got your donkey and your cart mixed up there laddie

[tight pollen]

Titles, Vectors 2d, Arrays of string, description etc.

all is in Structure

[dark drum]

Where does the data come from?

[tight pollen]

data is loaded in GameMode from SaveGameObject, if player join then get this data from GameMode

[dark drum]

How does the data gets saved to begin with (as in where does it come from)? Whats it for?

[tight pollen]

From PlayerState

in PlayerState i stores this data

and if Server click SAVE, then i get all PlayerStates and save this data in SaveGameObject

[frosty heron]

Wut 😄

I don't think the player should care or know anything from the Anim BP

it's the other way around

[lunar sleet]

Duro beat you to it

[frosty heron]

Just read 🫡

[tight pollen]

this data is there to be displayed in widgets

[dark drum]

but what is the data for? You say for displaying in widgets but this is a very generic response. Is it just health values? A collection of assigned quests? Total enemies killed? etc...

[tight pollen]

I have multiple widgets in the viewport and each has its own title, description, image, etc.

[frosty heron]

What's that gotta do with displaying it on widgets tho? If you store the data in the widget you need to rethink the choices you made

[frosty heron]

Store the title description image or anything that needs to be send over the network anywhere but in your widget

Like player name can be just in the player controller.
When someone join, server send RPC that update the widget while passing the playername

[dark drum]

Another generic response. 🤦‍♂️ As cold Summer has said, data shouldn't be stored in a widget and should have some sort of handler that it gets the data from. Making suggestions beyond this is going to be difficult with the details your providing.

ask in #multiplayer for optimised approach. Mp questions are tricky and should be asked to those that are doing it

Yeah im using it in another function...Hmm..

Is there a simple way to get around this or is this a huge headache?

I need it in the other function

[lunar sleet]

Well my point was is it overriding the value you’re setting here

[thin panther]

its going to be a headache somewhat. basically you only need to change it in one place.
Other places can apply a modifier to it, but really only one place changes it.

so you might have whatever executing it that says "add 200 to the modifier"

so it will use basespeed + modifier as the new walk speed. which would be 600 + 200
then something else comes in and goes "remove 50 from the modifier"
and at that point the speed is set to 600 + 150

how you manage that is up to you

That makes sense, thank you

[lunar mulch]

Im using it for this code so i suppose i am yeah :/

[lunar sleet]

See what cuppa told you

Timeline node is tricky.
Isolated a bug in my logic to my Timeline node which is 'stuck ' on Paused so Update only fires once instead of continuously.
Does anyone know why this happens and how to solve?

[lunar sleet]

Show the rest of the code, seeing 2 execution paths coming in, bit sus

[thin panther]

don't trust the watch either

[verbal lotus]

you need to plug in to "play from start" instead of play

if you just keep playing its never gonna reset

could be other issues but thats the most common

Hi all, little query...

I have a series of box collision volumes which, on a specific event attach an actor to themselves (e.g. if there are 8 box volumes, 8 actors are attached, one to each).

Under a certain condition I need to remove all again (the actors, not the box volumes).

I'm having difficulty finding the correct node. There's a GetAttachedActors, but thats all of the actors attached to any component on that actor. I'd like to be more specific and say "Get me the attached actor to this component".

Any ideas?

Hello 👋🏻 I’m in need of some guidance on data handling. Here’s my situation: I’ve got a substantial dataset in Excel, complete with columns for Key, ValueA, and ValueB. Now, my goal is to read this data based on the provided Key and, subsequently, pass it to a UWidget for the display of ValueA and ValueB. To put it another way, I’m looking to create something akin to a file or a global variable that can house a collection of objects, each with properties like Key, ValueA, and ValueB. These objects need to be accessible within a Blueprint, allowing me to perform actions like GetDataByKey. The dataset is quite extensive, comprising hundreds of items. Importantly, our UE project is entirely Blueprint-based, without any C++ involved. Your input and expertise would be greatly appreciated!
