This will get called before As AIC enemy AI is set

#

so you don't really want to access reference like this directly

#

instead create a boolean in your ANim Blueprint locally that is set from the value of As AIC enemy AI every Tick

#

See this example, we don't use Crouching directly from the reference, instead we set the IsCrouching in the Anim Instance

#

turns out I didnt need this I just had the wrong equation for my blueprint and was trying to account for nothing by using a thin Capsule

#

If you wanna know what I am talking about.

I wanted the animation to play only when within a certain rotation window to the left and right of the front of the blueprint box collision in the world (even if that collision is rotated). I got the yaw rotations in the world of character and blueprint and for some reason I had it adding them when character is negative rotation and bp is positive. How it is now is the right way

Sounds like something that could be done with dot product

Wait... Do I even need everything on the left? Can't I just plug the purple "Rotational region equations" straight into the branch on the right? It's all subtracting anyways right?

is there any way to store data which wont be reseted once a new level is loaded ? like i m storing some variables in my playerstate once a session is being created but it will reset once the new level is loaded. I wanted to access each player's player state from game state too.

gentle urchin
#

game instance is persistent

mental trellis
#

The game state has a list of all the player states.

gentle urchin
#

But those are not persistent

#

imagine client crashes during level change

#

then they will lose their data

#

if you save before level change, and just restore on map load this wont happen

gentle urchin
#

Yeah anything important id save tbh

Hi, I have datatable that consists actor and image. how to let system know that if I spawn Actor A only Image A appear in my widget, If Actor B Image B. Right now when I spawn actor A or B all Image A & B appear.

Hi, I’m having an issue with a widget system I’m creating to track consumable stats in my game (Wiki system).

I use two widgets (Wiki_Button and 1412, my Inventory). The system works fine when toggling the Wiki system using a button, but I want to move the widget initialization logic to Event Construct to avoid recreating the widgets each time. However, when I move the logic, the integer array values from my GameStats don’t update properly, and I’m struggling to figure out why.

*System Overview:
Wiki_Button Widget: Displays consumable info (image and integer showing the count).
1412 Widget: Creates 40 instances of Wiki_Button and arranges them in a grid. A custom function UpdateStats handles the updates.
Data Handling: The GameStats variable (struct with 40 integers) is pulled from my character blueprint, tracking how many consumables are used.
Issue:
When using a button to toggle the visibility of the Wiki, it updates Wiki_Button correctly. However, this approach recreates the 40 widgets each time, which is inefficient. I want to move the logic to Event Construct to just update the stats and toggle visibility, but when I do, the integer values remain the same across all widgets instead of updating correctly.
*What I’ve Tried:
I moved the widget creation and UpdateStats calls to Event Construct and used a visibility toggle, but the array values from GameStats don’t update as they do with the button click event.
Debugging shows that GameStats increments correctly when consumables are used, but the widgets don’t reflect these updates when initialized in Event Construct.
P.S.: The GameStats variable is working fine when debugged with print strings and tracks consumable updates correctly. Any guidance or suggestions would be greatly appreciated

I'm having an issue where a stat is not being saved despite me just adding stats that are saving yesterday. was wondering if anyone could maybe think of whats going on here.

#

As I add to the stat I can see that it is applying. but after leaving the game mode then going back in, it loads back to defualt.

versed sun
#

show where you are saving , the save node on last pic is clipped off

iron idol
#

the save system doesnt go anywhere after that. thats actually the load

#

the second pic is where its saving

#

it saves level, xp and health just fine but its not saving agility

versed sun
#

are you saving before the level change?

iron idol
#

yea

#

like i said the other stats are saving fine

#

as far as i can tell they are all set up the same which is why i'm confuesed

#

the level transition can be seen on the second pic after the for loop completes

versed sun
#

did you just add Agility to the CharacterInfoStruct? might be the BP struct bug

iron idol
#

i did just add it before implementing the rest of the save

#

i'm not familiar with the bp struct bug

versed sun
#

BP structs get finicky when you add members to them after you already have the struct in use . Like when you restart the project , anywhere the struct is might be broke with red pins

iron idol

its no though 🫤

Wanted to post this to raise awareness for those creators that may use BP generated structs and enums in your projects. TLDR: When you need to modify a BP generated struct or enum follow these steps Save your current work Make the change to the struct/enum (rename or add property/entry) Save the struct/enum Exit the editor WITHOUT SAVING any...

not sure if its your issue

also, the changing level on the same tick as saving the info...
Try a small delay between Loop Complete and Load

yea i actually just tried the last thing you suggested

no dice

hmm

put a 1 sec delay before load level

is the save a SaveGame ?

yea still not seeing the changes reflected. I've been at it for almost 2 hours and have no idea whats going on.

versed sun
#

no errors after restarting the editor

#

?

iron idol
#

no

#

and after looking at the forum post i'm not seeing any error reports in out log either

so i think theres something wrong with how the stat is being applied

#

nope nevermind. I thought it was but i tested another stat and that is in fact applying

Yeah, should be fine. Though I would maybe add them all, and then save to slot. This will cause a lot of disk writes.

iron idol
#

yea intend to clean things up along the way. just trying to get it functional at the moment.

#

I just added another stat to the struct and its loading and saving just fine

#

i'm so lost haha

#

I would consider it being because i'm pulling it from a component on the actor but im pretty sure some of the other ones that are bing pulled from there are working fine

Hello guys I was working on a first person game where character can also equip weapon so I checked some tutorials but most of them attached camera to the head socket which makes the camera shake when moving because of animation but I want stable camera. So looked furthur other guy did it but he made 2 meshs attached camera to 1st mesh and made it only owner can see and made another mesh for others to see. Is there any other way I could do it?

#

The thing is I don't know how to make the pitch rotation work if I don't attach the camera to work because the hands don't fixed but if I attached the camera to the mesh it shakes

#

I want the effect of dying light.

# visual ember just don't attach to socket then?

If I don't attach to socket then when I rotate in pitch it don't align with the spin movement and face appear in front like camera is inside the face. If I remove the rotation part I don't know how to make the hand gun holding position absolute with respect to camera pitch rotation

Hey folks, so I have a multi sphere trace on tick, and I need to fire an event once every time a new actor is hit by the trace, and another event when a previously hit actor isn’t being hit anymore.

#

Currently I have this. The new actor hit event works, but the actor not being hit doesn’t. Any ideas what’s wrong?

How can I stop this sphere from damaging other spudbugs? this is in the supudbug character blueprint

#

I am assuming the problem lies here, I don't think I am referencing it correctly

image.png
#

I would have assumed saying don't damage self would include others of the same blueprint, but that is not the case

visual ember
#

one way would be to use collision channel that excludes the bugs specifically. less performant option would be to check on collision if the hit thing is a Spud Bug. if not, then proceed to damage it

is there a way for an actor to know if he is getting hit by rays?
lets say im casting a ray on tick from the character's camera and sending a message through an interface. is there a way for the actor to know when i look away?

simplest method would be
Sphere overlap -> for each entry -> if entry cast to SpudBug fails -> damage it

you're casting SELF to spudbug, that's redundant

Hey guys, I'm trying to implement a bolt action sniper rifle that uses procedural animation for its bolt-sliding mechanism after each shot so that the animation lands accurately on the bolt. I'm using this because I have dash and double jump animations that will cause the bolt-sliding animations to be inaccurate.

Has anyone done this? I tried using control rigs but it doesn't work really well. It's really hard to get the character to always target the bolt while playing the bolt-sliding animation. The hand is always placed either too low or too high

rugged wigeon
#

You should very rarely need to use the play animation node.

#

basic ongoing animations based on the character state should be handled by the animation blueprint. One off purposeful animations should be triggered as a montage.

if i put an enemy (blueprint) into my world

is there a way to save the world location into a variable?

to keep that position as reference?

crude pike
barren tangle
#

but it's during the code. i was more thinking about a variable that is automatically set based on the actor location. maybe on the constructor... but not sure if it make sens to put it there. or maybe on event beging play to set the location

crude pike
#

ahhh

#

yea that's probably the best bet then, if you only need to set the value once then you can just fire it in the EventBeginPlay and not worry about it later

#

Idk how anything about the performance cost of doing it in the Construction Script but if you need to access the variable in the Editor directly, then yeah you can do it there

I have a "Call in editor" function that spawns a bunch of child components, like spline meshes, child actors, static meshes, and attaches them to the actor from which the function was called.

It works fine, but whenever I move the actor, or reload the level, all those child components get destroyed.

#

Any way to prevent it?

#

The construction script is empty

#

So it shouldn't override the call in editor function

visual ember
# trim matrix Any way to prevent it?

C++
Here's a piece I made that allowed me to add components like that. RegisterComponent and AddInstanceComponent were necessary IIRC. Though I was adding component from another component, so you might want to play with it and see which combination works for you.

mental trellis
#

To get all static mesh actors? To get all static mesh components? To get all static mesh assets in the content browser?

distant grotto
#

for a line trace target

mental trellis
#

Not really. If it has a unique bp you can use that as the actor class, but that's not a good way.

#

You would need to save a reference to the actor somewhere.

distant grotto
mental trellis
#

It's actually relatively quick because all teh class instances are hashbucketed.

#

But it's just not really extensible and prone to bugs. What happens if, in the future, you want to put 2 of them in the level? Or you accidentally spawn 2 of them and then wonder why your code doesn't work?

distant grotto
#

oh right

#

Well I know theres just going to be 1 in this case

crude pike
#

actually just on that topic real quick, does UE have a way of making sure there's only one instance of a BP (and never any more than 1) in a level?

Star Engine has a GUID thingo you can enable on Entities to make sure that there's only ever one of them in the scene (e.g only ever one instance of the Player, or a specific cast member). So if you try to place another instance of that Entity in the level, it throws an error because there's already an entity with that GUID string. Does UE have that?

How can I uncap the FPS? I have a project that is capped at 30fps and I want to uncap to see how well it runs.

fiery swallow
#

I think 0 completely uncaps it

noble ledge
#

Didn't change it

#

Its bouncing like 30-31. Like its capped at 30 or something.

fiery swallow
#

Think you might genuinely be getting 30 fps, I'm almost positive it's t.MaxFPS 0

#

In the console

#

Try t.MaxFPS 15

#

And see if it drops your frames

visual ember
fiery swallow
#

Console commands override that I'm pretty sure

noble ledge
#

oh wow. 15 did lower it

fiery swallow
#

They override everything

#

And once you setup a console command, the engine cannot re override it with lower calls

visual ember
#

but t.MaxFPS 10 didn't change it for me either, so I bet in @noble ledge case it's just a poor performance

#

or magic

any one know why Get ref is not there ?
I need to mess with the original items and not a copy with this one

#

Because it's an array of references, if you copy a reference it's still a reference to the same thing

#

The only reason to get a ref in this case would be to change the array element to a different reference, but at that point it's just another way to set an array element

how do I pass a variable to a child from parent? (i.e. gun damage to the bullet class it spawns)

high iris
#

How does one decide between using the concept of owner vs concept of instigator? Is it fair to say that if it's an item on a character, like an equipped weapon, "owning" the weapon makes a tad more sense than the character being the "instigator" of the weapon? But otherwise if the character shoots the weapon, the character is the instigator of the action of shooting someone else?

fiery swallow
#

Actually, I'm pretty sure multiplayer is "owners" intended use

rugged wigeon
# fiery swallow I agree with the instigator part but owner plays a crucial role in multiplayer a...

is that true? that doesn't sound true. I haven't done replication stuff in a long time but why would the it matter which actor spawned an actor? Off the top of my head I don't think this owner is related to whether the server or the client owns the actor. I'm pretty sure that's just a function of whether it was spawned on the client or the server (and 99% of the time you just want to spawn any non-trivial actor on the server)

Does anyone know why when button is clicked it is not adding to viewport? I suspect it's due to the sort order

rugged wigeon
#

I take it back. I guess it calls GetOwner() repeatedly until it finds a playercontroller.

rugged wigeon
inland walrus
#

Thanks dude

fiery swallow
#

It is a crucial part in unreal engine multiplayer replication

#

If you don't understand how ownership works you will quickly find yourself confused on why some RPCs work, and some do not

rugged wigeon
#

this is a dumb question but whats a common example of an owned actor, that is not the possessed pawn, needing to trigger an RPC on the server?

fiery swallow
#

Controllers and possessed pawns, another example would be having a gun in a shooter game. If all the logic was inside of BP_Bazooka for example, and trying to fire the gun required Server call. You would not be able to do it unless you had ownership

#

This is why other players cannot force you to jump or fire your weapon for you, or reload and etc

#

Even though they have a direct reference to your character

rugged wigeon
#

But I guess my mental model for how most people code things is you have some sort of antecedent character action, like firing the gun; and the firing action would occur on the server which would in turn cause the gun to shoot and replicate that.

#

although yes I follow your example

fiery swallow
#

The firing part always occurs on the server, but someone has to tell the server to actually fire the weapon

#

And that can only be done by whoever owns the actor

rugged wigeon
#

what I mean is I feel most setups would have the client tell the server that the CHARACTER wants to do the firing animation, which in turn triggers the shot to actually occur

#

in his case it doesnt really matter who owns the gun, right? Because the player ownership for establishing who has the right to begin the firing sequence was respected.

fiery swallow
#

I think we might be getting too specific with examples. At the most basic level, who ever owns the actor is allowed to tell the server what to do. 😄

#

If no one owns it, no one can tell the server to do anything with it

rugged wigeon
#

yeah I think I'm fine

fiery swallow
#

Also implies that the server owns everything by proxy, so it always has the right of way

#

Glad i could help clear it up a little

I just ignored it 😔

iron idol
#

I'm at a total loss here.

frosty heron
#

not sure, but let's hear it

#

maybe someone else have clues

iron idol
#

yea i've run it by a couple people yesterday but everyone seemed to think it shouldn't be happening

#

oh man i dont even know where to start

frosty heron
#

Goal and the obstruction toward the goal maybe

iron idol
#

so i have that save system. i'm building a leveling system where i can let the player choose a stat on level up. I'm going to say this bit because i saw something about a bug in UE, though i'm not convinced the bug is an issue. I used an enum to decide what player has leveled up then direct it to the proper widget

#

from the widget the player then can select the stat and it adds to the stat

#

but the stat is not saving

#

to make sure it wasnt the process or the struct, i added another stat to the struct and hooked it up. that one saves.

#

so lemme show some code

frosty heron
#

unfortunately, my brain shutdown when looking at other people code. I can only help with the basic of save and load

#

For simple setup, you probably want to load from main menu and use that save game object to save and load

#

I think rather using enum you can pass the actual character that level up?

iron idol
#

so this save system is actually to go between different game modes

#

maybe though i'm not convinced the enum is the issue.

frosty heron
#

yeah, I think the save system it self should not coupled with the game mode at all

#

unless by design for specific reason

iron idol
#

i got it from Ryan Laley, and its because of the way my game handles game mode transitions and how to party is controlled

frosty heron
#

for a start you should never fallback to a delay, especially for a save system

iron idol
#

that was added after

frosty heron
#

you want to broadcast at the end of your sets in the save game object that the saving is completed

iron idol
#

while trying to figure out what the problem was

#

i can just delete it

#

i was making sure the save actually finished before the transition which wouldnt have made sense anyway since its off the complete of for loop

frosty heron
#

yeah, that's fine but for production, make sure to have a callback when the save game have finished saving

#

rahter than hard coding a time

iron idol
#

this second picture is where i am setting the stat

#

i thought this might be the issue. but then i added a new stat to the struct and that one applies and saves fine

#

which doesnt make sense

frosty heron
#

What's the actual issue?

#

something doesn't save?

iron idol
#

a single stat is not saving

#

despite adding an additional stat the exact same way and the new one saves

frosty heron
#

which stat? but the rest are fine?

iron idol
#

yea

#

even the one i added after is fine

frosty heron
#

not sure without thorough debugging

#

have you tried deleting the .sav file and start a new one?

iron idol
#

yea multiple times

#

i kinda have to to test it

#

since its on level up

frosty heron
#

Nothing much I can say sorry, If I were you the only step I would take is to add a break point and see the code line by line

iron idol
#

the only other things i can think of as to why this specific stat might be different is its 1. in a component attached to the actor, but i have others that are set up that way and are fine. 2. I'm using the stat for a timer thats paused durring application

frosty heron
#

perhaps a print string, Checking if the value that is being saved is correct, then making sure the value is set in the save game object, then finalyl checking if save game object is saved to slot

iron idol
#

man this ones actually got me nervous

frosty heron
#

would start by checking if the value is correct just before save game to slot

iron idol
#

yea

frosty heron
#

if you ain't getting a correct value to begin with, the save ain't gonna be right

iron idol
#

theres a print string in the screenshot

#

thats to check that the value has been applied

#

it does reflect the change. but then i have a print at the start of next combat and the value is back to default

frosty heron
#

just check if the SaveGameObject->TheVariableYouWantToSave is set correctly

iron idol
#

hmm. i dont think it will make a difference but i'll try it there

frosty heron
#

because if that's correct and you succesfully save it to the .sav, I don't see any reason you wouldn't get the same value when you load the object again

iron idol
#

so the save happens on another widget after this widget has closed

#

i should put a print with the stat right before for loop?

frosty heron
#

Right before SaveGameToSlot

#

just check the value of the variable you are saving

iron idol
frosty heron
#

not there

iron idol
#

the second one?

#

gotcha

frosty heron
#

yea second one

#

@iron idol Btw the one that you failed to save

#

it's not the XP right?

iron idol
#

no thats an old variable i just have not cleaned out yet

#

i changed where the xp was located

#

so i cant retrieve the variable the same way in the save system

iron idol
frosty heron
#

remove from parent doesn't even destroy the widget

#

Widget gets destroyed when it's unreachable

iron idol
#

yea i didnt think so but im just grasping at anything

I was under the impression that when that call "item picked up" Node is run, (it's from an interface blueprint) that it will trigger that event "Item picked up" node from that same interface blueprint function, in the second blueprint

lunar sleet
#

Your current node isn’t sending any message (envelope icon)

gaunt cypress
#

And how do I set the target if you will

lunar sleet
#

Iirc for one make sure only the receiving actor implements the interface (the sender cannot implement it if you want it to work)

#

Then, use the Message version of the node to send the message

gaunt cypress
#

Interesting, that is probably the problem then

#

Yeah I had it implemented in both

There should be set resolution and apply setting in the game settings object

i asked chatgpt but its settings are not even there in Unreal engine .. maybe for older versions it showed data i guess 😅

Er, just took out the implementation in the first blueprint, not sure how I'm supposed to use that function now though

Does anyone know how to duplicate an item in an array? I tried SetArrayElement in 2 different indexes but it only shows up in one ( It's an inventory )

Anyone know how to fix the camera jittering when using the lock-on? When unlocked, there's no issue, however the way the lockon is set up it constantly tries to stay focused on the target, for normal play and movement this is fine, no issues, but I also have a function where when the player throws an attack with a locked on target, it attempts to rotate the player to face them, this also attempts to rotate the camera as a component of the player with them, causing the two functions to fight and create this jittering effect as the rotation moves the camera and the lockon nudges it back on target

May need to size to fit

pallid gorge
# warm grove

If the array has no existing space at the supplied index set won't work as there's no entry to set, you would need to add a blank entry and then set it or add directly to the array

warm grove
#

it's like this, im dragging a bomb to another slot, and i replaced add item with add 2 items , the second one at the next index, but it doesnt show up

pallid gorge
#

Checking the size to fit option should solve it but you may want to define your size elsewhere if it's an inventory

gaunt cypress
#

Yasss I got it working tysm @lunar sleet

pallid gorge

warm grove
#

when i add +1 to the index and i do a normal AddItem, it ads it to the right slot to it

pallid gorge
#

But on the grid is it just top row is 0-5, 2nd row is 6-11, etc?

warm grove
#

yes

pallid gorge
#

What's the for each index node doing in this scenario?

warm grove
#

the thing is, i think the item becomes 2 slots

pallid gorge
#

I think you're gonna have to back out your scope here if you want help, a lot of what's going on here seems to be happening in other places we can't see how it functions

warm grove
graceful sage
#

Probably best to learn what it's doing first

pallid gorge
#

^

#

Can't really help diagnose if we don't know the intended chain of events to begin with

graceful sage
#

Right click and find references and you can go through the code and study it

warm grove
#

I just wanted to know what's the normal way to duplicate an item in an array

graceful sage
#

It's kinda contextual

warm grove
#

Like is that SetArrayElement is normally supposed to do it?

graceful sage
#

It's a way to I suppose but without knowing what the loop macro is doing can't say

warm grove
#

So the macro function is OnDrop, after I dragged and released an item

#

Its on the InventoryGridWidget

#

It checks for space before

#

It normally adds it

graceful sage
#

I'm talking about for each index

warm grove
#

ok lets see

pallid gorge
#

Also a problem you can probably avoid now is you don't seem to be duplicating that space check for your additional item, so if the first space is clear, it would potentially just overwrite anything in the following needed spaces

graceful sage
#

You're probably overwriting indexes

#

Lol yes

pallid gorge
#

But again, without knowing how it's checking space to begin with might be the culprit of why it's not working anyway

warm grove
#

ok im gonna show it

graceful sage
#

Yeah so the first time it does index 0 and 1 second 1 and 2 overwriting the duplicate etc

warm grove
pallid gorge
#

What is this "top left index" variable? Is it being set by something? Otherwise wouldn't it just always be 0 if you're using linear indexes? The indexes shouldn't care about the grid factor unless they're not linear

warm grove
#

Its the top left index of each item

pallid gorge
#

What does that mean?

graceful sage
#

It's an input which I'm guessing is doing a for loop

pallid gorge
#

I get that but I'm saying it's odd to me that it's labeled top left because 1. that implies it's checking 2 factors to get top and left which wouldn't be accurately represented by an integer, and 2. I haven't seen anywhere where this actually gets tracked so either it's not hooked up when it's supposed to be or it should just always be 0 anyway

warm grove
#

so this is for each index

pallid gorge
#

What is this function? It's multiple loops that run into each other and output multiple times to what end?

warm grove
#

it's one of the macros of the InventoryComponent

pallid gorge
#

So this is the literal For Each Index function

#

But... that outputs 2 X and Y integers and the function you showed in the other screenshot outputs a Tile struct

warm grove
#

yea you can break that struct

#

into x and y

pallid gorge
#

It's still odd to me that it doesn't create that struct anywhere in the function but okay, we'll run with it

warm grove
#

so each slot has x and y

#

when i test the index, it shows O O

#

0 1

#

0 2

#

until 4, then 1 0 i think

#

each slot is like that

pallid gorge
#

4? What is the significance of 4? Your inventory is 6 slots wide, and supposedly linear.

warm grove
#

oh yea until 5 then, i thought its 5 slots wide

pallid gorge
#

The image you showed is 6

#

It would read as 5 I guess

#

But that sounds like your indexes aren't actually linear then?

#

Its separately defining rows and columns

warm grove
#

yes

#

you can just set the number of rows and columns in the component

#

and it changes it

pallid gorge
#

So, if I'm understanding this system correctly, I think we're back to where is the "Top Left Index" variable getting defined for use in adding the item?

warm grove
#

looking for it

#

found it

#

so the isRoom function takes it from here

#

and

#

So actually this is the function that is called to check for available space

pallid gorge
#

But this still pulls it from this "Dragged Item Top Left" so we still aren't seeing what it's actually getting from this variable

warm grove
#

yes just a sec

#

ok so this one is big let me see how to take screen

pallid gorge
#

Honestly I think you're better off scrapping the entire "add2" approach and moving your attention before the space check happens and figuring out a way to just tell it you need to run this check multiple times on different indexes, otherwise you're going to get into a pandora's box scenario where your function no longer works for adding 3 or 4 or so on

#

What i need is when i drag from a stack isntead of an item

#

to leave the original item there(the stack and -1 to the stack) and also bring it to the new spot

#

that was the idea

pallid gorge
#

So what does this have to do with adding 2 items?

warm grove
#

because i wanted to add 1 in the on drop location, and 1 in the original location of the stack

#

and just set the correct stack numbers

pallid gorge
#

Well you shouldn't need to add 1 in the original location, I'm assuming these stacks already have a variable defined for their count?

warm grove
#

yea so thats the problem, when i drag from a stack to somwhere else , the dragged item doesnt show up

#

actually it becomes part of the dragged item from

pallid gorge
#

Just -1 the stack and then create a duplicate item when you drag it instead of dragging that item itself

#

With 1 as the quantity for the duplicate

warm grove
#

yea the stack -1 but the new item just doesnt show up

#

the slot is empty and it actually is part of the dragged from item

#

thats why i tried to add 2 items

#

it only adds 1

#

functionally the new location becomes part of the initial stack

#

when i drag others on that ghost slot, the original stack increases

pallid gorge
#

But what happens to the original stack?

warm grove
#

however i tweak it, either the original stack dissappears, or the new location item dissappears, but actually they merge

#

functionally they become 1 item

#

with 2 separate spots

pallid gorge
#

Are you dragging the original item or making a copy?

warm grove
#

im using that add item at function

pallid gorge
#

That has nothing to do with the drag/drop operation

#

Your drag and drop is literally 3 separate items, the location you can drag items onto is an item, the item occupying that location is an item, and the item you're moving around when you drag them is another item

#

It's 3 separate entities passing information to each other with each action so what you need to do is figure out what's actually happening when you drag it

warm grove
#

yea im working with those spots, its OnDragDetected

#

When it drags it calls a drag drop and then remove from parent

#

i tried to remove the "remove from parent" node, but then the new location doesnt work, it become ghost slot

pallid gorge
#

Yes, so you don't want to remove from parent when you're dragging off a stack, you want to have a way to execute a separate function that just -1's the parent and creates a duplicate with 1 set as the quantity to drag instead

warm grove
#

yea yea

#

thats what i kept trying

#

the -1 is easy

#

it just cant seem to duplicate

#

it becomes 1 item

#

with the 2 both slots

pallid gorge
#

You'd have to see what is happening in the drag operation and what data is being transferred when you do that

#

It's likely referencing an object directly so if you take out the remove from parent, it's just not removing it from that slot, but everything you do to the object still affects it

#

Hence, you need to make a copy

warm grove
#

yea like how do i make a copy

#

so this is currently OnDragDetected

#

omg is it that i didnt return the operation on true???

pallid gorge
#

It's not executing anything for stackable items at all right now it looks like

Hey folks, so I have a multi sphere trace on tick, and I need to fire an event once every time a new actor is hit by the trace, and another event when a previously hit actor isn’t being hit anymore.

Currently I have this. The new actor hit works, but the actor not being hit doesn’t. Any ideas what’s wrong?

rugged wigeon
#

looks like new hits is empty at the time you're checking if it contains things

#

assuming its a local variable

true sierra
#

At first it is empty yeah, then it skips the first check and proceeds to the next one

#

Which will add new hits

rugged wigeon
#

is it a local variable

true sierra
#

It’s not

rugged wigeon
#

is it because you're testing with just one unit and this entire thing doesn't do anything if nothing got hit

#

you're also removing an element from an array while looping over the array which is going to break things

true sierra
#

I shall try then updating the arrays after completing the loop, instead of on each loop

rugged wigeon
#

are you testing with more than one unit

#

because your code won't do anything if the only unit in the area isn't hit

#

there is no reason for this

true sierra
#

That branch just checks if anything is being hit, if false it doesn’t do anything. My multi sphere trace checks for anything being hit by that trace channel so it can return multiple actors in that initial array

rugged wigeon
#

and thats wrong

#

because if you have one unit in new units and it is no longer hit; you want to do something.

true sierra
#

Ah

#

Makes sense

#

That could be it

#

Gonna test it asap, thanks

Hi everyone👋🏻

#

I have a problem that i cant think a solution of. So i have a character blueprint and i scale the character ,the game is about scaling. And the problem is that the camera is also scaling ,and its weird when the character has a big scale

image.png
#

so its like this when scale is 1

#

how can i fix it

spark steppe
#

the solution is math (trigonometry to be precise)
or cheap out and try your luck with find look at rotation

I have a template asset from MP where AI Enemies attack my player

However when i add many enemies they all come at once and trap me where theres no escape

How can i make them attack like 2 at once or just 3 not all

random pulsar
spark steppe
#

ofc it is

#

you have to adjust the camera rotation

#

or position

random pulsar
#

i heard of camera manager,and that its more flexible than having the camera in the player

#

am i right?

spark steppe
#

i doubt that this will fix your issue

random pulsar
#

how would you fix it,if being in my place

#

oh

#

nice

#

i have an idea

spark steppe
#

with math

#

as proposed before

#

or aim at component, not sure if it would work in that case

random pulsar
#

what if i add a value to the target arm length when he is scaled

spark steppe
#

sure, add 42

random pulsar

yeah adding a value to target arm length helps

@spark steppe Do you use spring arm for your game? It never become a solution for me. Especially when hitting corners.

The camera penetrative feeler from lyra saved the day tho... and my camera movement doesn't look crap anymore.

Gonna repost from reddit if that's ok:
"Currently I'm using an input action, doing some checks for things like not crouching, jumping, swimming, things of that nature to make sure the slide is possible, then I'm using a timeline to shink the capsule collider, change the mesh Z location, and change the speed over time.

It totally works, but I'm wondering if a timeline is the best case for this. I want to be able to make the slide time, slide speed, and slide "friction" variable, which doesn't seem to be possible with a timeline.

I found the finterpto function, however that requires a tick, and would be wasteful for a slide mechanic.

Does anyone know how to better implement this?"

Hey this is my animgraph and you can see I have a layered blend per bone node which I play montages through to blend with my standard locomotion, however when I play montages it's not blending per bone... my character comes to a locked stop while playing the montage until it's over. I thought layered blend per bone was supposed to let you move while playing the montage?

#

This is my settings for the node

It was working before, however my motion matching PSDs somehow got corrupted, so I just remade my entire motion matching system and now suddenly I can't move while playing montages

Can we open levels with a given gamemode?

soft lion
jolly oracle
#

Well, if I have 3 different gamemodes that I need to progress through this is fine then?

soft lion
#

Yeah if you want to set up a function that opens a level in the game mode go for it why not

#

Put it on the player controller, inside the player, inside a level transitioning component does it matter

#

As long as you know the game mode in your current level gets destroyed, and the game mode for the next loaded level is created

jolly oracle
#

I should clarify:
Server: Picks a 3 random maps.
Server: Will also need to choose 3 random game modes
Server: A, "match", would be the progression through each of the maps, each with a specific gamemode.

soft lion
#

Oh you didn't mention it was multiplayer

jolly oracle
#

--and I just don't know about it.

soft lion
#

How can you pick a random game mode? You have to set the game mode in the level settings before you package it. How do you set the game mode for a specific level at runtime?

jolly oracle
soft lion
#

I think it's no problem opening random levels, but they need to have defined game modes

#

So sure make capture the flag, team deathmatch, extraction, battle royale mode all their own maps, or hell even make multiple copies of the same map with different game modes

jolly oracle
#

I didn't know that had to have pre-defined gamemodes as the gamemode only exists on the server? So that's why I was curious.

but look where are you gonna put this logic that players should never touch? Character class default info? No way clients are deciding their character class info. The server is the only thing that has a connection to which enemy spawners spawn what and tracking all the enemy kills and player scores. Also specific overrides for PostLogin, PostLogout those specific times that logic doesn't exist anywhere else like it does on the GameMode.

GameMode.jpg
jolly oracle
# soft lion but look where are you gonna put this logic that players should never touch? Cha...

I haven't gotten that far yet. Right now...what I'm doing as a place holder is putting all of my "server tasks" in a blueprint class that's created alongside the game instance. I'm guessing I'll have to write some sort of manager class that keeps track of a "match" as the game goes on.
UNLESS there's some ThInG that the engine has for this functionality.

I haven't really poked around in the gamemode class itself. If there's an option to just leave it as one gamemode class but change the rules between levels. That's fine too.

soft lion
true sierra
soft lion
#

The game mode can change its values at runtime, but I'm really not sure how you could do like making it where the server selects a set of rules for the next level's loaded map because the game mode for the current level is destroyed before the game mode for the next level is created. They have no way of communicating and there's not a way for you to say "Ok game on your next level load use these settings in the future" and then you generate a game mode class with those loaded settings

jolly oracle
soft lion
#

When the GameMode is created on level load it always loads default values then changes what it needs to while playing

#

If you need different default values between different levels the only way I see it is different game modes

jolly oracle
#

--with different maps.

Hmmm....tricky busines.

I'mma dig around. And see if I can't come up with something before work. DX

soft lion
#

What if

#

hear me out

#

What if you had a settings struct or something that existed on the GameInstance instead

#

you could make it where after the game mode is created you could get the game instance and retrieve those values and set the settings maybe

#

The game instance lives for the entire session the game is open

#

So like make a function the server can decide a set of rules in a struct that you define, and then it packages one up, sends it to the game instance and then waits for the next level to load?

In my Stand In Server class:

Manual loop through a list of map names add random 3 to a set. 0, 1, 2 <---Return
Manual Loop through a list of gamemodes....with string aliases...add random 3 to a set 0, 1, 2 <----Return

call this function from the game Instance through my constructed BP.
Convert the lists to arrays pass in (0, 0) to the open level node appending (prepend?) the Gamemodes aliases with, "Game=", <Alias Name>

Each level and Gamemode rattles off a lil message on each of their begin plays!

Man I BELIEVE you. I've damn near come to hate Unreal Engine.
I am not writting code for each independently yet.
But that fighting with every damn part of the engine the entire way...almost convinced me I can afford another monitor.👊

But I just don't know what the f the engine is doing between modules.
And while I'm also learning c++...well I just gave up with unreal plugins.
And this seems to be my problem.
Epic announces some feature I think it would be nice.
I try to make use of it (as good faith towards good practices) and it just doesn't work somewhere along the way.
Something just Does. Not. Work.

My initial thought of approach was to have the server set up so I can prototype in a more "live" setting but Epics solutions literally just drove me to the point of...
hate. I couldn't manage the EOS (And the entirety of that hot mess of naming stupid conventions)
So I tried the SDK. Everything was fine...Up to a point.
After that. I just said Fuck it.
Went to steam...Paid the 100 bucks. (Jumped the shark a bit)
Grabbed the sdk.
And it just....worked.
Just toying with it out of the box.

It's documented and I'm sure there's thousands of people that have real working products you could reach out to for help.
UE5, an aftethought now. I don't know if I even have any singular game in my steam library that uses THIS version of the engine.
And as far as I'm aware. I don't know any games that have launched with this version of the engine.

But yeah...I feel what you feel but a few floors down.

Found the fix: Make the sphere the default scene root, apply transformations to it till it is normal and then delete it

#

seems like the default scene root will inherit the properties of what was deleted to create it

Hello! I am having a very weird problem.

I have a system setup to simulate realistic collision with the default VR Template hands using physics constraints. Now, the problem is is with the colliders that are attached to the finger bones.

When moving your hand around and colliding with objects, they work and stick to the bones perfectly! However as soon as you bend your fingers, it just floats.

I attached a YouTube video showing what I mean.

Don’t mind the colliders rolling around I was just testing with one collider for now haha

https://youtu.be/irTKEX3nn2Y

I can provide any screenshots that anyone may find useful! I'm going nuts tbh haha

While this is using VR, I don't really think its a VR specific issue so I'm posting it here. Sorry if it's not the right place!

#

For what

barren tangle
#

or it's something to manage with the max walk speed an acceleration

gentle urchin
#

No, you cant include a curve

lunar sleet
#

Nothing to do with the move to node

gentle urchin
#

you'd need to append that logic manually

barren tangle
lunar sleet
#

That’s a CMC/ pawn movement thing

#

Maybe you can do something on the pawn movement component, but this does not tie into the AI much. The AI tells the pawn to move and where to go, not how fast, etc

barren tangle
#

but ok 🙂

lunar sleet
#

Nothing prebuilt afaik

barren tangle
#

ok 😦

#

so mixing that kind of movement with a behavior tree seems to be complex to put in place

gentle urchin

its mostly something like
OnTick -> ShouldMove? - true -> Accelerate_Clamped() - false -> Deaccelerate_Clamped()

and is there a way of doing pressing e to interact(it sends alot lines) but after collision happens it stops for a duration or stops for good till holding e again for interact

gentle urchin
#

why would you cast self to object

#

generally you'll never need to cast self to anything

#

everything that self is , can be accessed directly

#

Also, generally, I'd recommend to always make things a variable, and not rely on hardcoded values

#

in this case it would be a float "InteractionDistance"

crisp moon
#

ohh it works thanks

crisp moon
gentle urchin
#

this part

where you multiply by a hard coded value

you should multiply with a reasonably named float

reasonably named

#

is also important

#

Ofcourse, it only needs to make sense to you/your team

yeah yeah sorry for that i was just rushing to reply to you

but yes, like that, a variable

I am often running into the issue in unreal of not knowing how to best handle changing a value dynamically.

For example say I want to have a headtilt that happens when you move to the right or left, you need to smoothly change that variable constantly to either slowly tilt to the right, left or revert to the neutral position based on your input. But whenever I implement these kind of things they kinda feel.. bloated? I feel like there's a better way to do this. What's the normal way of handling stuff like this lol, I feel like this should be very easy but that i'm doing something wrong to make it feel bigger than it needs to be.

I think this is the cleanest I could get so far. This was for a flying vehicle which rotated a bit based on whether you go up or down

image.png
#

Is there like a easy common practice way I never heard of or is this pretty common

gentle urchin
#

I'd just do it on Tick

#

using things like Velocity, Heading direction, Target direction and so forth

#

the bigger the delta between current direction and target direction, the bigger the tilt..
or based on current rotation delta

sand bloom
#

Hmm so a tick function, I guess that would be cleaner and not too different in terms of performance loss vs this tween thing

gentle urchin
#

Im personally not a fan of having a ton of things on the input events themself

sand bloom
#

Me neither

gentle urchin
#

they serve to do and handle the inputs, not all the glossy extra effects

#

So it would be something like

Tick -> UpdateTilt(float Delta) -> UpdateFlaps(float Delta)
sand bloom
#

I'll go tinker with a tick function to kinda compare and see if that's easier for like organization sake thanks

gentle urchin
#

I'm also a fan of wrapping things up in functions

#

keeps them easy and 'separated', and lets the event graph largly work as an overview of the logical execution

#

easy to see "oh shit, i updated Tilt() before Flaps(), yet Tilt() relies on Flaps() final values !"

sand bloom
#

definitely agree on that, I could just collapse it in the event graph as a node thing which would work similar enough

#

but functions are just more convenient

#

and let's me find stuff relating to it quick

obtuse oriole
#

but I am more specific on what object that camera see, basically I want to recreate a robot facial system from some other game where they have a plane with shapes of the face and a camera where what the camera render with pass through some kind of post process effect to make it pixelated and slap it onto the robot's face

maiden wadi
#

You simply use a SceneCaptureComponend2D. This works similar to a camera. You can place one at the same place as a Camera if you want. This renders to a texture. You can then use that texture as a texture param in the material you're using as the screen.

#

The robot thing might be slightly different.

obtuse oriole
#

well I assumed that's how it worked since I saw exactly that setup in the playground mode the game has

#

just a flat plane on the world origin with the robot face and another plane above it of the rendered face with the pixelated post process applied

frosty heron
#

Just know that scene capture is expensive

How do I open the Blueprint Data window, the one that's open by default when opening your blueprint?

sand bloom
#

apparently structs are pretty much notoriously bugged for blueprints in unreal

tfw renaming a variable crashes unreal 😩

#

how do they expect you to do these things without structs is what I want to know because inventory systems need to handle a lot of data

#

Genuinely just lost when a basic feature of the engine is just broken

#

Do people just forgo structs altogether for some kind of alternative in blueprints?

#

I heard there's an alternative somewhere

dire frost

#

I read about that too but couldn't find a way to do it

dire frost

also you get to have struct function and can also define operators in there (like ==)

Hi all, I open a widget on tab button and want to close it also on tab button. For this I use Set Input Mod Game And UI, that would work keys in the inventory, because if the Set Input Mode UI Only is enabled, they do not work and therefore can close only on the widget button. And in Set Input Mod Game And UI I can close on the tab button, but if I clicked on an item in the inventory, I can not close until I clicked on a place outside the inventory. As I understand it, this is due to the fact that these two modes are turned off. How can I do it right?

#

Sort of annoying double work

But also.. they got native header previews now, so im sure they could make a struct editor that simply made the native struct directly. Would solve most issues

whats the easiest way you can think of to add an afterimage effect on a character? i tried using the snapshot pose node in BP, but to no avail.

rugged wigeon
#

probably a niagara system that leverages the skeletal mesh

I don't think I should fuck with c++ right now, I am not in equipped to learn all that stuff now. Maybe I can make a empty actor as janky struct alternative for my needs? we'll see

sand bloom
candid sentinel
rugged wigeon
#

that should be doable if you're generating particles off of the skeletal mesh

I suppose you could look into creating a render target image saving it and then turning that into a afterimage somehow but that might be convoluted..

I don't think you even need the bottom half for bp but you might as well

Stupid Question of the Morning: I am attempting to get all actors in an array, and print the name of the first actor in the array. When I use BP_Bob (name Bob) it prints Bob twice, when I delete BP_Bob and only have BP_Steve (name Steve) it prints Steve once

image.png
iron idol
#

i might be wrong with this one since i have not done this

#

but put the array in a For Each loop?

copper chasm
#

Nope, that prints Bob AND Steve, and does it twice, lol

iron idol
#

Steve's are often problematic...

copper chasm
#

Oh huh, if I delete Steve, it only prints Bob once

#

So I assume it's doing something with the number of characters in combat, and not the actual list of characters in combat

#

I bet if I put in 2 Steves and a Bob, it'll print 3 bobs

iron idol
#

turn based combat yea?

#

I would think the for loop method should work here. but someone can correct me if I'm wrong. it might be a problem eslewhere. just my 2 cents.

rugged wigeon
#

shrug. You're welcome to a different opinion, but I would strongly voice that the gameplay of baldur's gate 3 was just not very good because it's based on the 5e system which is just not very good. Larian's previous title, Divinity 2, was much better in terms of gameplay.

promote the sound to a variable when you play it

cyan berry

nono it is a variable

#

how would i reference the variable tho

if the trigger isnt there to cast to

You'll just need to figure out something that makes sense to get a reference to it. Worst case being "Get Actor of Class"

but now its not letting me stop the sound-

drag off of get actor of class return value

you also shouldnt need to get actor of class and cast

oh

iron idol
#

actor of class should be enough

#

try dragging the return value into target

cyan berry
#

WHAT

#

i didnt know i could do that

iron idol
#

but i would think you should just be able to drag off return value and search for stop node

rugged wigeon
#

Your problem is that your grotesquely named "New Var 7" is a sound cue, not an audio component.

cyan berry
#

if i make it an audio component i cant reference my sound tho

iron idol
#

can you just destroy actor?

rugged wigeon
#

iirc calling "Play Sound" means you're telling to play and have no option to interact with it again

cyan berry
#

yk i actually didnt think of that

iron idol
#

just destory it all together

#

off the return value

rugged wigeon
#

if you want to make it something you can continue to interact with you should spawn it as an audio component

play 2d is also a good option for a one off sound

You should probably toggle their visibility after 3 sec instead

Hi guys! I have a question but hate to interrupt the flow of things, do you mind if I post my question? Or can you let me know the best way to post it?

jolly oracle
# frosty heron I would say yes, don't bother? Just use cpp and wrap it with the pre processor ...

I want to script server-side logic.
There's a few things I am not understanding when it comes to blueprints and Dedicated servers:

  1. What on earth happens with blueprints during the packaging process.
  2. What happens when blueprints are compiled?
  3. Do blueprints run on some virtual system during runtime? Or do they become c++ equivalents?

If I wrap a class with a preprocessor that is extended for blueprint Use:
What happens to the blueprint? 👀
Where does it go?🤔

So if Annnnyone wants to throw me a bone it'd be nice.

quaint fable
#

that makes sense lol. Well I have it so the level sequence possesses the Player character after overlapping a trigger. For some reason when the player spawns in, they automatically start at the start location of the sequence, rather than the player start. why is that?

opal snow
#

So I have a few TriggerBase blueprints in my game and they work as intended in the editor, but they don't work with the packaged built version. Other trigger boxes work though. What can be causing this?

quaint fable
#

I also have the character being un possessed when the sequence starts that way the player can't interact until the sequence is complete. How can I have the character be re-possessed so they can interact with the world afterwards?

frosty heron
#

In cpp it's as simple as adding #if server

If my memory serve me right

#

You can expose the function and code to blueprint from cpp but still wrap the actual implementation with the pre processor block so even if the class got packaged, the code is not

jolly oracle
frosty heron
#

I think you are confusing the concept

jolly oracle
frosty heron
#

It's like this if i make an online game

jolly oracle
#

Ok

frosty heron
#

I want some script to only exist in dedicated server

#

So when I package the game for my server using server target

#

Only that .exe have the script

jolly oracle
#

Right

frosty heron
#

When you build for client they won't have the script

#

If you just need to ensure the server does some things (not building related)

#

You can just check with the IsServer boolean node

#

So your script still get packaged to client but it won't run the script because of the conditional check

jolly oracle
#

interesting.

frosty heron
#

But since the script exist in the client, it can probably be hacked but you shouldn't make competitive or hard to cheat game if you don't have the man power or someone that knows what they are doing

#

I'm starting to learn Mp too, not gonna worry about cheating too much

#

That will just hinder my progress

jolly oracle
#

I mean...I am reading what you're saying but it's not making sense. Just between the whole packaging thing.

It's a super useful node, but it requires that you constantly save all of the BPs using it for the referenced class, which is somewhat of a source control hassle

Im trying to use the Two Bone IK node and I’m very new to animation blueprints so any help would be appreciated…I have a socket on a weapon (static mesh), how do I use my weapon socket’s location as the effector location for the two bone ik node? In other words, how do I set the two bone ik effector location to follow the location of the socket on my weapon?

It’s 100mb now? It was 2GB before I thought

Print string also make sure you set the reference.

If you get accessed none then that's your clue.

What would be the best way to check if an enemy is within a player's view?

Idk bout the best way, there are many ways, depending on what type of game you’re making

#

Line traces, AI perception system, dot product, etc

I'm assuming by players view you're not referring to them actually being rendered on screen

#

If so then dot product for sure

I'm thinking usinging a "Line of Sight To" check with the player, and then checking if it's within the camera frustum

Dot product is a cheap start

#

Well, an assumed camera function given that it's on the server and we don't know the player's aspect ratio

gentle urchin
#

Followed by an actual linetrace

fickle lichen
#

Yeah

gentle urchin
#

Or maybe 10 traces, idk

How would the dot product be used in this case
