blueprint

[trim matrix]

lol

[lofty rapids]

so then it's not set up correctly

you can test it with just the b key

right and search key b

scroll to the key b

and use that event just to test if it works

you'll have to fix your input setup if that works, because your keys are firing but the event not working

[trim matrix]

still nothing

[lofty rapids]

^

[lofty rapids]

well if you b key isn't firing off

then it's not the setting

it's the fact it's probabl in the wrong bp

because if you set the event b key

and used pressed

and it doesn't fire then for some reason your inputs are not firing

not really a matter of how your context is all set up

[trim matrix]

using the b key by itself didnt work

[lofty rapids]

did it print anything ?

^

because it realy matters what bp you put these on

[trim matrix]

no didnt print at all

[lofty rapids]

it really matters what bp you put those events on

so where did you do that ?

[trim matrix]

the events are in the same blueprint as the rest of the doors code in the door blueprint

am i just completely oblivious lol

[undone sequoia]

Anyone know how to add bullet trail effect for bullet?

[lofty rapids]

they need to be in the player bp

or the controller

[trim matrix]

so just copy them over?

[lofty rapids]

i would just delete and remake

but this time you don't need to get player

and cast, because now those variables are local your in the player bp

[hollow cove]

look in to the niagara system for doing that

[trim matrix]

ok so i got that to work so for the unlocking how would i do that? just get the doorblueprint then destroy actor?

[lofty rapids]

so you want to unlock it and the next time the collision happens don't show anything right ?

[wise ravine]

works flawlessly 👌

appreciate your help man

[trim matrix]

yes and save it like that so if the player comes back to the level later the doors still unlocked

[lofty rapids]

well thats a bit harder to do, so you want to save it on the actor and save that across levels

for one thing you'll be most likely using game instance

[trim matrix]

save it on the placed version of it bc i plan on placing multiple making them possibly for a hub world, or alternate paths in levels

[lofty rapids]

you want this unlocks to save when close and re open the game ?

[trim matrix]

yea if the game has saved, i was planning to impliment autosaving

but saving the game from a menu

[undone sequoia]

YE but i know nothing about 😦

[lofty rapids]

#niagara

[lofty rapids]

one way might be to give each of them an id, and then you can check an array of say UnlockedIDs

where you would just add to the array an id and it would be unlocked

but also a boolean on the actual actor

unlocked

[hollow cove]

what i like to do when i know nothing about an area of unreal engine is go through the documentation, page by page, making my own thing while going through their examples. i also take notes in obsidian so i can refer back and refresh myself if i get stuck. https://dev.epicgames.com/documentation/en-us/unreal-engine/creating-visual-effects-in-niagara-for-unreal-engine

[trim matrix]

i have a bool to check if its unlocked or not

[lofty rapids]

so it works but you just want to save it across levels ?

[lofty rapids]

^

[trim matrix]

how do i do that

[trim matrix]

i dont have that bool set up

im guessing id do it like this?

no, im wrong 💀

id add that after making the unlock happen?

[lofty rapids]

right once you unlock it flip the bool

and then run a branch on the overlap or you could event turn collision off

[dawn gazelle]

If you're modifying the index if you've found an item, and using the "First Empty Slot Index" if you didn't find the item on pickup then that part should be set up right. Your problem now probably has something to do with your dropping logic.

[lofty rapids]

you may even want to use the actual player collision for that where you can use other actor and cast to the item saving it in a variable and checking if it's valid so you have a reference, otherwise you'll need get actor of class and try to find the exact one wouldn't really work with multiples

[stoic ledge]

I have a game instance subsystem which only exists on the servers game instance. Then i have an actor placed in the world that trys to use a function in the subsystem, but it claimes it cannot find it. Is there an obvious reason that this happens?

[remote rapids]

i need help

i wanted to keep music between levels so i did that

this is a game instance blueprints

and in my main menu i did that

all works good
if now i go to another level the music is keep going all good
the problem is that for example lets say
main menu is A level
and the other level is B level

so i go from A level to B all good the music is good
but i have a return button to A level.
so When i am on B level and i want to go back to A level so the music, its sound like it duplicate it self and that not sound good.
how to fix that?

someone try to help me

[dawn gazelle]

We already discussed this.#blueprint message

[remote rapids]

but i didnt understand

oh yes its you

can you keep explain me pls?

[dawn gazelle]

You check if your "Audio" variable is valid.

[remote rapids]

i stuck here

[dawn gazelle]

That was answered for you too by someone else.. Use a branch.

[trim matrix]

it's fine, since the variable is still valid on that 1 frame, it's marked to be deleted to the GC

he should just set it and not get it afterward but yea I see that it's solved

[dawn gazelle]

If valid, don't create and check if "Audio" is playing, if it is, don't play, otherwise, play.
If it's not valid, create and play.

[remote rapids]

that good?

[dawn gazelle]

That is a branch yes.

[lofty rapids]

you saying if it is valid then create again ?

i think you want the opposite

[trim matrix]

he doesnt create it, he play it

the variable is prob set at compile time

[trim matrix]

not sure if you need to create the Sound 2d if you already have it, btw

[remote rapids]

so how to set it if is valid so dont play it

[lofty rapids]

so you just want to create it and play it once ?

[dawn gazelle]

You do understand the concept of something being true or false, yes?

If valid (ie. TRUE), don't create it. Check if it is playing, if not, then play.
If not valid (ie. FALSE), create it and play it.

[remote rapids]

okay, i have the main menu level
and i have the other menu level

i want the music to start when the game begin and continue when i move to the other level.
all work good like i did.
but the problem is if i go back from the other level to the main so that not good its like the music is duplicate

[remote rapids]

yes

[lofty rapids]

well unfortunately that variable will reset anyway

[remote rapids]

main menu

[lofty rapids]

if your loading a level

[dawn gazelle]

No, it'll stick.

[remote rapids]

game instance

[lofty rapids]

ok it's in the game instance

just do isvalid, and on false run it

[remote rapids]

i understand what @dawn gazelle but i dont know how to translate it to blueprints

[dawn gazelle]

It's a literal translation....

don't create. Check if it is playing instead.

if it is not valid, create and play.

You have the check to see if its valid.
You have the nodes you need for creating and playing

[remote rapids]

okay

okay

[dawn gazelle]

The only thing you might be missing is checking if "Audio" is playing, which should be pretty self explanatory.

[remote rapids]

i think its good now

[dawn gazelle]

Right on 😄

[remote rapids]

dont laugh if not...

that working now

[dawn gazelle]

What the IsValid does is basically seeing if the object contained in the "Audio" reference actually exists. When it's null, or pointing to nothing, then the reference is not valid, thereby you go ahead and create it, and then you're populating the variable with the return value from the Create Sound 2D, thereby making the reference valid, so in the future when you enter that function again and check if it is valid, it should be valid since you already set the value once before 🙂

The extra bit of checking if it is playing if it is valid is just to make sure in case you stopped it for some reason that if you do happen to return to the main menu it will automatically start playing again.

[trim matrix]

how would i set up the unlock?

[lofty rapids]

^

[trim matrix]

inside the door blueprint or the player blueprint?

[lofty rapids]

you want when you press a key right ?

[trim matrix]

yea when u press a key

[lofty rapids]

so one thing you may want to do is on your player when you overlap set the interaction actor to what ever you overlap, and on end just clear the variable, other than that i'm not sure how you would pull the variable on key press

i don't think get actor of class would work since you may have multiple

so i would set an interaction actor on overlap

where then when you press the key, you can get it's reference from the variable

[trim matrix]

so, add clear variable to the end of the door blueprint?

[lofty rapids]

one thing i probably already mentioned is you probably want a parent class for all these

and you can put variables on that

it makes casts a lot easier

[trim matrix]

its in a class of its own already tho i think

[broken badge]

Anyone know how I would automatically load all Blueprints within a content folder into an array. BUT without using the Asset Registry (because that apparently doesn't work in a packaged project...)

This is what I have now

[lofty rapids]

so in your case this would be on the player, and you would cast to you actor that your using with these doors

and then have your normal stuff on key press

but then also use the interaction actor reference so you can set it's variable

[trim matrix]

so move the code thats already on the overlap?

[lofty rapids]

leave everything the way it is

just add some stuff to your player bp

[trim matrix]

but what is the new overlap from? or is it the one from the other bp

[lofty rapids]

its just so you can get the reference to that item

so you can set it's variable

because when you press the key the event is on the player

you need a reference to that specific item so you can set it's variable

[trim matrix]

but what am i doing to get the new overlap nodes in my player blueprint?

found it

so make a new variable thats interaction actor?

or promote to variable

[lofty rapids]

or you can promote to variable on the begin, then just do an empty set on the end

or you can just create an actor object reference

[trim matrix]

i had a reference to the actor already as a variable

[lofty rapids]

so now you just gotta check if stardoor is valid when you unluck, and if so set it's variable

[trim matrix]

which input do i need to add the is valid to?

the unlock

[lofty rapids]

right because you want you unluck to set that variable so the next time you over it doesn't set ui and run

[lofty rapids]

ok now at the end use a stardoor variable, and drag out and set the variable

[lofty rapids]

definately not

[lofty rapids]

do a get not a set, then drag out ans do "set is open"

[lofty rapids]

there ya go, are you using that variable in a branch on the other actor ?

[trim matrix]

i need to be, i hadent had it set up

[lofty rapids]

make sure it's still working the way it should be

it's just that it won't be unlocked yet

and will just keep popping up

[trim matrix]

so where am i putting that branch in the other actor?

[lofty rapids]

do you only want this to work on this particular actor ?

or is it going to be reusable ?

[trim matrix]

i wanted to be able to place multiple in levels and have some of them be different values

[lofty rapids]

think about it for a minute, you set the variable to is open, now when you goto overlap you want to stop execution based on that boolean because you set it to true now, so use a branch and run it on false so when it is true it doesn't run

similar to when you did the movements

when that event fires

run it based on a boolean value

[trim matrix]

im confused

add it here?

or in here

[lofty rapids]

hmm

you want it not pop up so add the branch before the code that pops up the message

[lofty rapids]

what does dismiss prompt look like ?

[lofty rapids]

should work ig

when you change levels it will go back so you'll need a way to save that and load them up again

like i said probably give each one an id, and have an array that is all the open id's

it involves a loop but if you don't have a ton then your fine

[trim matrix]

how do i give them ids?

bc i may use some for a hubworld that may have a few, and will have some with different values needed for stars,

[lofty rapids]

the different values need i think you covered with the required stars variable thats on the door bp right ?

[trim matrix]

yea

[lofty rapids]

you can just create a variable on it called id and name them unique names

[lofty rapids]

even use a count lik item1, item2 etc...

and require stars is expose on spawm, instance editable ?

this way when you put them in the world, you just edit the variable for each one if it's set correctly

[trim matrix]

it is set w those now

[lofty rapids]

ok, so now place another one down

and when you do that, check in the details if it has required stars

you should be able to change that and then it will unlock with that amount of stars

[dusky cobalt]

Is it possible to set Param and then use it like that?

[trim matrix]

yea it worked

so now all i need is the door to become hidden and the collision set to disabled once unlocked?

[lofty rapids]

maybe #materials ?

[open crypt]

I can't find this on the damn graph to disable, clicking on it does nothing

The blueprint won't compile and is being a dickhead - nothing was broken I've been using this MC for the past day fine

[sour cliff]

I have a character blueprint in map as my main character , how do i swap it with a child actor of it

[lofty rapids]

are you spawning the character or did you set it in override ? you should be able to set your game mode override pawn

[trim matrix]

Can anyone explain to me shortly how a drag system is made? with the mouse clicking and dropping an image..

[minor creek]

is this the right node to replace with?

[high iris]

Assuming a first person view, what happens when I rotate my currently possessed character? It doesn't look like the camera itself gets rotated with the character, so I assume the camera and the mesh are now out of sync, pointing in different directions?

[mild rapids]

how might you shoot a ray in the direction the gamepad stick is facing? e.g. if I push the joystick up, it shoots directly above the player and if it's facing left the ray also shoots left and if the joystick is facing diagonal the ray also shoots in that direction.

[trim matrix]

how can i make another prompt pop up when the player dosnt have enough stars but tells them how many they need, i made the widget and a reference to it,

[lofty rapids]

i would probably set text like you did with the stars required, but do it for the actual prompt, then set it before you add each time

[lunar musk]

This are my dropping logic

[mortal cradle]

I'm in a process of swapping my entire communication from casting to interfaces. And I wanted to know, is there any other known issue with a large amount of functions in one blueprint interface other than potentially less clarity? As far as I know performance impact is minimal.

[dry sleet]

Not really, add as many as you need.

[dawn gazelle]

This sounds like a bad move. There is nothing specifically wrong with casting and interfaces are less performant and make it harder to trace your code. There is a time and place for interfaces but just outright not wanting to cast is not one of them.

[flat coral]

What's the right place for a "singleton" style reference, for something that there's exactly one of per level?

Specifically, in this case, a map camera pawn

Actually wait I'm dumb I can just flip it and have the pawn populate itself into the gamemode or whatever

[mortal cradle]

I will be casting sometimes, I unnecessarily said "entire communication". Now I want to avoid casting to the player which I've done a ton and made a lot of the BP's ~300mb when they should've been in kb's. When there was something that would be accessed by a couple of scripts, I would place it on the player, eventually I got to this massive memory issue.

[broken sluice]

I'm trying to set up a ladder climb mechanic and all of the tutorials on YouTube show how to swap from walking to flying when within the collision box of the ladder.

This is fine although it prevents jumping off the ladder. Is there any way to enable jumping while in flying movement mode?

[dawn gazelle]

That could potentially be fixed by changing your player to have few asset references in it (like no sounds, no meshes, no materials, no vfx, etc.) but create a child class that has the assets in it that you actually use for spawning. This way you can pass around your player class reference that has few assets with minimal impact to other blueprints.

[high iris]

What's the best way to let designers using blueprint know which of the variables are internal state which they shouldn't need to worry about, and which ones are variables they should tweak to their heart's content in order to modify the gameplay as they see fit?

[faint pasture]

don't let them see the ones they aren't meant to care about

[high iris]

Does that typically mean to not make them instance editable?

[sour cliff]

I didnt find an override pawn , where do i find that option

[lofty rapids]

world settings, game mode override, then you have to pick a game mode, you can create an empty on for now if you don't have on or not using it, then you can change the pawn

default pawn class

[sour cliff]

Yes but then how do i change that pawn at runtime using bp

I want to be able to change it to a bp_child version of it

[lofty rapids]

ok so at runtime

then you want to possess it

you can possess any pawn i'm pretty sure

[sour cliff]

Even if its not spawned yet

[lofty rapids]

no, it's needs to spawned then you possess it

[sour cliff]

But would it override the existing pawn I'm using or destroy it

For example the main character is Superhero pawn and i want to be able to switch between batman and superman at runtime

[lofty rapids]

it won't destroy it

but you won't be possessing it or moving it

so if you want them to stick together thats a whole other thing

[sour cliff]

Nvm thank you so much i used an array variable with different pawns and i am switching based on index

[lofty rapids]

why are you using two widgets ?

and the second one you added is an invalid reference based on the error

[trim matrix]

so make it apart of the other widget?

[lofty rapids]

so make the text that appears a variable like you did the last, and set its text the same way

but this time set to the proper one for the proper branch

so that you have a text in the widget, and when you cancel and want to show the other message you just change the text

you may want to empty out the required text as well

[flat coral]

Am I doing something wrong here? This event IS setting the arm length to radically different things, but the camera never moves

Oh of course I figured it out the moment I asked... Needed "Tick while paused"

[open crypt]

What a stypid game engine - you can't even restart a streaming level without manually deleting everything in it

[lunar musk]

@dawn gazelle Can u help me with this?

[faint pasture]

Editable, visible, whatever you need.

[dawn gazelle]

This whole series is concerning.

1. You're calling to spawn the actor from the inventory component but later on you're running something on the server.
2. Your widgets should not be updating themselves based on the drop, instead, the drop should signal to the inventory component that something is requested to be happening, and then the inventory component manages what happens and the widgets can update themselves based on the new state of the inventory. You're clearing the item info of the slot, again before running on the server to actually modify the inventory. You should only be updating the widgets based on their actual state.
3. You're allowing clients to send the "item info" for the item to remove - your clients could potentially spoof this and doesn't actually indicate to the server the actual index of the slot that should be removed, so then you don't know what the server may be doing.

Your widgets should have a reference to the index of the slot of the inventory they care about.
You can have an event dispatcher on your inventory component that your widgets can bind to in order to and call it when the inventory array gets modified so the widgets then know when they should update themselves based on when the inventory is changed.
Again, just because you requested to drop the item, you shouldn't have the widget assume everything is good and visually remove the item info
Don't rely on the passing the item info around. If you're using a slot based inventory based around an array, then use the array indexes to refer to the slot in the array that the widget cares about, this allows you to notify the inventory component of the specific slot you're trying to manipulate. You shouldn't need to store the item info in the widget at all - you just read the info in the array of your inventory component.

Basically.....

On Drop > Notify Inventory component the index of the slot that was dropped > Inventory Component can RPC that to the server to request the drop with the index of the slot that was dropped > Server validates what is in the slot and spawns the actor and removes the item from the slot > OnRep of the inventory array should trigger which you would then use to call the event dispatcher > Widgets that are bound to the event dispatcher would fire and can then read the inventory array at their assigned index and refresh what they shoul be displaying, if there's nothing in the slot then it can clear the visual, otherwise, display what is now contained in it.

[ruby cobalt]

I have a value that I interpolate but it's not linear.. most of the effect happens between 0. and 1... but I need to go all the way up to 20.. how can I change that curve? to make the transition more linear?

aka: i suck at math

oh that might be a good one for ai

i don't ask ai about unreal stuff usually because it's so misleading

but this is basic math

[lunar sleet]

More #game-math than #gameplay-ai

[ruby cobalt]

ah i didn't know about game math

i meant asking literally chat gpt about the problem

[lunar sleet]

You can make curve assets

[ruby cobalt]

oh that's a good idea...

I'm sure there's a node with a basic math function that can get me close though.. but yeah custom curve is more intuitive for me to do as I don't know much about math

[stoic ledge]

i can count, and i tilt my head.

[green lotus]

Hello, I'm trying to make a procedural Dungeon generator but I keep on getting an infinite loop with the following function and I'm not sure how to fix it.

This function simply creates a new collision box that should spawn where a new tile would spawn and check if another tile exists in that space. If a tile does exist, then it will append it to an array. The array is later checked to see if it is empty or not and will generate a new tile based off of that information.

Currently, from testing, it seems like the spawned collision box keeps colliding with one particular room infinitely for some reason and I'm not sure how to fix it.

The log print statements prints the box that it spawned and any members that it collides with and the latter is always constant before crashing from an infinite loop.

Here is the function that calls the function above

[stoic ledge]

i dont get it

[green lotus]

what

[stoic ledge]

is the box not moving?

or is there something in the space?

[green lotus]

I managed to generate this much and paused before crashing

I think it's claiming that there's something it's overlapping with when there shouldn't be any

[stoic ledge]

is the next spawn trying to fill the middle space at the top?

[green lotus]

I don't know where the next spawn is trying to place as the collision box actor for some reason doesn't appear in the outliner

[stoic ledge]

im just guessing, it might not like being wedged in. seems it works to a point

[green lotus]

what does this mean?

is the box too big?

[stoic ledge]

is your collision box set to the maximum area size?

[green lotus]

collision box is slightly smaller than the actual tile size

[stoic ledge]

i donno, make it small enough to see iftheres an issue there?

[green lotus]

I added a cube to the collision box actor and it looks like the reason it's crashing is because the actor isn't being properly destroyed?

[stoic ledge]

What does it mean!

[green lotus]

There should only be 1 cube at a time, yet there exists 3 here

It crashes right after multiple are spawned at the same time

[fiery ridge]

are you having an infinite loop?

[green lotus]

it says it's an infinite loop

because the previous actor isn't being destroyed

despite having a destroy actor node

[fiery ridge]

the loops do everything in one tick

[fiery ridge]

so actor needs to be destroyed

[green lotus]

it is being destroyed

[fiery ridge]

and then the loop starts?

[green lotus]

it's being destroyed after it's finished being used within the loop

it's created and destroyed once per loop

Less blurry version

[fiery ridge]

i dont see the loop here

[green lotus]

loop is here

too big to put in 1 picture

recursive loop

[fiery ridge]

looping without forloop nodes?

[green lotus]

it's a recursive loop

think of it as a while loop but as a function with conditions to stop it

[fiery ridge]

you have 2 delays there. loops and delays are very prone to crashes

[green lotus]

theoretically the loop shouldn't cause an issue? which it doesn't seem like it is? but the main issue I'm seeing right now are the actors not being properly destroyed

[green lotus]

crashing due to infinite loop

[fiery ridge]

add a breakpoint to the destroy actor node

[green lotus]

I added the delays so I could see what was going on before it instantly crashed

[fiery ridge]

see if its firing

[stoic ledge]

it seems like the main issue

[green lotus]

It is firing

it is firing until right when it crashes

[stoic ledge]

try to narrow down with some prints to see the destruction happening.?

[fiery ridge]

does the editor crash or just ingame?

[fiery ridge]

yea

[green lotus]

now im getting nullptr exception (I think?) for some reason

[stoic ledge]

now u did it

[fiery ridge]

wait, why are you appending a room if there's a room there already?

[green lotus]

what

where

[fiery ridge]

"If a tile does exist, then it will append it to an array" do you mean empty tile?

[green lotus]

No

If the array is empty, it indicates that there is nothing overlapping, therefore it can generate a new tile

[fiery ridge]

ok and when do you need to destroy actors?

[green lotus]

so if I append it to the array if it exists, then it inidicates that there is an existing tile there, so you should not generate a new tile

[green lotus]

I'm creating a new collision box to check if the tile it wants to generate already is overlapped by another tile

so after it finishes checking, it is no longer needed so it should be destroyed

[fiery ridge]

why not line trace ?

[stoic ledge]

...

[green lotus]

idk

im new to unreal

[fiery ridge]

im working on similar dungeon myself but there's no need to create a new actor just to check for collision

[green lotus]

was following this tutorial and was trying to optimize it

[stoic ledge]

"so after it finishes checking, it is no longer needed so it should be destroyed" so it should create them until it satisfied, then destroyes the boxes?

[green lotus]

tutorial was suggesting creating an entire new tileset and then checking, and then destroying the entire tile again, which would prove tragic on larger tilesets

[stoic ledge]

also i can see those boxes phasing through the wall..

[green lotus]

it should create one box, check if it is being overlapped, if so, append to array, if not, do nothing, and then whether or not it did anything the actor should be destroyed

[fiery ridge]

look at this loop. the actor checks if there's no collision in 4 directions (grid movement)

you can do the same logic

[green lotus]

the thing is it's generating multiple at a time

[fiery ridge]

in my case, it's 300 units exactly away

what's your tile size?

[green lotus]

400

wait

I might be wrong

[fiery ridge]

ok so it's much better to linetrace

[green lotus]

i have it scaled 10x the original size on the x and y axis

for the floor

[fiery ridge]

how many units away is the center of the tile to the next one?

[green lotus]

uh

[green lotus]

1000?

[fiery ridge]

ok, so what you do is you Line Trace from the center of your current tile, to adjacent directions with 1000 units away

and return the line trace bool true or false

if true, create a room

you can use a vector array for 4 different directions like this

im assuming you want to create rooms in 4 directions (grid based)

[drowsy anvil]

Hello, how do I make a blueprint that copies my player's rotation for another character?

[stoic ledge]

i think you would just apply the rotation from one to the other.

[fiery ridge]

GetActorRotation

[green lotus]

What if I want to append another room to the existing room that is larger than my current size?

the main reason why I'm using the overlap boxes is so that I can create a bigger room using more tiles and just append it on there

[fiery ridge]

you mean you have a bigger room and you want to create a smaller room next to it?

[green lotus]

or vice versa if the space allows

[fiery ridge]

ok then you just change the line trace distance

instead of 1000, you trace the center of the bigger/smaller room

[green lotus]

is line tracing more efficient that overlap boxes?

[fiery ridge]

so if you're in a small room, and the big room's center would be say 5000 units awya, you do 5000 trace

[fiery ridge]

absolutely

but also, use more For(Each)Loop

since you're dealing with many arrays

[stone obsidian]

Hey yall im using UE5 and followed a tutorial for inventory and items, I made a health item that restores the players health when used from the inventory however I want the item to not be consumed if the players health is full any idea on how to do this? I tried creating a branch with the condition of if the players health is less than 100 then true into the heal effect

[fiery ridge]

got any screenshot

[stone obsidian]

yeah one sec

when consuming a item is the assigned effect

[fiery ridge]

where's the branch for if player full hp

[stone obsidian]

one sec

[green lotus]

how would I get the direction to spawn the line trace from the exit point? would it be the get world rotation node?

[fiery ridge]

you mean how to trace from point A to be?

B*

[green lotus]

yes

[fiery ridge]

i assume you want to trace in 4 directions?

[green lotus]

just 1 direction

I'm generating 1 room at a time

because I am blocking off some rooms

[fiery ridge]

yes but does it know in which direction to spawn?

[stone obsidian]

originally I put the branch here but that wouldnt make sense cause the player could still consume

[green lotus]

yes

there is an arrow pointing in the direction

red arrow

[fiery ridge]

then put GetActorLocation on Start and add 400 units to the End

400 units depends on X or Y

you're not using Z i assume cause you're not building vertically

[fiery ridge]

run a print string on FALSE and see if its firing with player max hp

[fiery ridge]

wait

[stone obsidian]

yuh

[fiery ridge]

your checking to see if its LESS than 100, which means it has to be 101 hp

replace that with <= node instead of just <

[green lotus]

how do I get it to do it automatically figure it out?

it's giving me all 3

axis

[stone obsidian]

lemme try that

[fiery ridge]

make a vector array like this:

this checks all 4 directions

leave Z 0, dont touch it

[green lotus]

but how does it know when to use which index?

[fiery ridge]

it will use all of them

and give you true/false for every item in the array

and them, you use only the one that returns true

[stone obsidian]

it says I accessed none tho the variabe is set as the bp of the character🤔

[green lotus]

it keeps on giving me 3 axis with the multiply node

[lunar sleet]

How did you “set” it ?

[stone obsidian]

object ref as a single

[lunar sleet]

In details panel?

[fiery ridge]

Right click and make it float single

[stone obsidian]

wdym exactly?

[lunar sleet]

This is not how you get a ref. You’ve taken an empty bottle and stuck a 7UP label on it, now you’re trying to drink from it.

[stone obsidian]

W

ok erm

cast to player?

[lunar sleet]

If you want to get your player char ref, use get player character function

[stone obsidian]

gotcha

[lunar sleet]

At some point you may wanna watch bp comms live training pinned here

[stone obsidian]

🫡

[green lotus]

Would something like this work?

[stone obsidian]

im new to bp stuff but im tryin

[lunar sleet]

Ik, but that is a very good resource to understand this stuff

[stone obsidian]

no for sure I getcha

ill look into it

[lunar sleet]

Basically what you were doing is just saying this empty variable will be of this type, but you need the actual instance of the player

[stone obsidian]

lemme try getting player and see if that works

[fiery ridge]

Not sure why you need actor scale

[lunar sleet]

So get player char -> cast to the player char bp, and SET that as the variable you created, to save the ref in it

The cast will also ensure your player is actually there and loaded so you won’t get that error, it’ll just fail silently if it must

[green lotus]

so I can automatically determine the size of the tile through its scale and multiply it by 100 to get the distance i need to trace on bigger/smaller tiles

[fiery ridge]

i need a clearer picture. are you making a randomly procedurally generated room tiles adjacent from a single room?

[green lotus]

yes

[fiery ridge]

ok and whether the next room is small or big, is also random?

[green lotus]

for now it's the same size, but I'm planning to make different siezes

sizes

[stone obsidian]

does the set need to be before the ref is called in the branch? cause this doesnt want to work either

[fiery ridge]

I'd say finish the small one first. then you can add a variable in the bigger rooms that stores the distance. then in the loop, you use that distance instead

[green lotus]

would multiplying by actor scale not work?

[stone obsidian]

im sorry if this is babys first bp and im just dumb lmao😭

[fiery ridge]

theoretically yes not sure if it's the best practice

[fiery ridge]

is this multiplayer

[stone obsidian]

no

[fiery ridge]

why these nodes

[green lotus]

tried this and immediately crashed for infinite loop

[fiery ridge]

the forloop isnt connected

[green lotus]

oops

[fiery ridge]

Exec>Loop body

[green lotus]

Still crashed for infinite loop

[fiery ridge]

make sure the Exit Point is at dead center

[green lotus]

exit point is dead center on the edge

[fiery ridge]

this means your code is going wrong elsewhere

[stone obsidian]

So the video I was watching was setting as server and stuff for multiplayer I just kept the name sake for ease of following along

[fiery ridge]

this loop only fires 4 times since there are only 4 items in the array

[green lotus]

It's complaining about the function

[fiery ridge]

yeah absolutely not, leave multiplayer alone, its a completely different ballgame, especially for beginners

i cant stress that enough

[stone obsidian]

yeah I wasnt trying to do multiplayer but the "best" tutorial or one of the most popular one is of a guy setting that up I tried to do most of the same stuff just not doing the multiplayer stuff he did

[fiery ridge]

most tutorials are not that reliable

they usually show "bandaid" solutions,

and they dont scale well

but in your case, i would suggest blueprint interface

[green lotus]

It still crashes for infinite loop after generating ~2 rooms

[stone obsidian]

A brothers gotta learn some how and its usually youtube tutorials for me, I started learning unreal towards the beginning of this year

[fiery ridge]

try to refactor most of your code, try to simplify it with this ForLoop method i showed you

[fiery ridge]

my biggest personal advice would be to stay away from multiplayer. that shit is hard even for intermediate developers. but it's your choice

[stone obsidian]

Im really not trying to do multiplayer rn not until I understand a lot more, it just so happened I needed to code an inventory and the tutorial had some multiplayer elements

[fiery ridge]

inventory is also hard with blueprints. try making a simpler inventory with arrays

[stone obsidian]

I have done three inventory's now and god damn it is the worst. I dont mind coding with bp but yeah this one seems to work the best so far. Idek where I would start with arrays😵‍💫

[fiery ridge]

it is indeed hard

[stone obsidian]

I wanted to do it first tho with this project im working on because I knew I was gonna need to do it at some point and would rather get most of it out of the way now

[fiery ridge]

i'd say to do the other way around. finish your fundamental mechanics of your game

[stone obsidian]

https://tenor.com/view/gulp-cat-gif-27257259

genuine reaction

[fiery ridge]

your problem with doing inventory now is that you don't know how it will scale later on with your other stuff

you might end up refactoring everything

modularity is key to good "code"

[ornate apex]

Does anyone know how to deal with this I've tried everything.

In use pin <Unnamed> no longer exists on node

Its an error that causes packaging to fail. I've tried refreshing nodes, deleting and remaking entire blueprints, validating/fixing redirectors. No idea what else to try at this point

[fiery ridge]

find the node, post a screenshot

[stone obsidian]

very true, I just wanted it to be simple use item, item does thing with hotbar that lets you equip said items but idrk what im doing

[fiery ridge]

know anything about blueprint interface?

[stone obsidian]

I would like to think I know some yes

im kinda just picking things up here and there as I go on

[fiery ridge]

interface is good, because you just build the logic on the item itself and it does stuff whenever you use that item

[fiery ridge]

like "this item will heal for 27 hp whenever its used".

[fiery ridge]

are you also making multiplayer?

[stone obsidian]

I have it set up rn so I can pick up item go into the inventory use item and then according nto what effect bp I have made and set for that item it will do different things

[ornate apex]

yeah but its not related to packaging

[stone obsidian]

I use milk it heal player but I dont want player to be able to consume milk if players health is full

[fiery ridge]

one simple way would be to have a MaxHealth variable and use a boolean to fire false if HP is already at max

[stone obsidian]

ill give that a shot

[fiery ridge]

HP var and MaxHP var, if HP => MaxHP, do nothing

else, heal

and then on your player BP, whenever you get healed, check to see if your healing has exceeded your MaxHP

so you dont want to get healed say from 97 to 122 or something

you just reset the HP to current MaxHP

[stone obsidian]

ok ok

got it😎

[fiery ridge]

sorry friend, i dont do multiplayer, maybe someone else can chime in

[outer terrace]

so i have 1 WidgetComponent that does not save parameters.. specifically i need to reset it from world to screen space every time i restart the editor regardless how many times i try to save it.. is it a corrupted blueprint or like.. how can i fix this? its driving me crazy

[craggy flicker]

What would be the best way to hide and show items from a hotbar inventory? I already have actor references to the inventory, but I'm trying to decide if I should just set them as "invisible" or spawn new ones

like imagine you're using the scroll wheel to switchbetween items

ok now that i read from text, probably just hide them

[stone obsidian]

After my whole character mesh broke and caused my game to shit the bed I have fixed the health thing kinda

the player still consumes the item but the effect is not working when the players hp is full which is good

[stone obsidian]

can anyone help im trying to set a certain item effect as the condition for the true on the left branch but im not sure how to get it

second picture is kinda shitty but its the last row whihc is item effect which is a class

idek if its possible to put a ref to an item class into a true false but I would assume so?

this looks like a mess but is working😭 I can not use a consumable with the "heal player" effect if my health is greater than or = to my max

[sacred parrot]

so im making a random pickup system using an array, randomly select an int and use a select node to select which class. i wanna make it so once a class is picked up, if that class has already been picked up, make the ammo count to be max ammo. whats the best way to do that?

[heavy plinth]

Hey guys I'm having a bit of an issue: I'm having the aiming animation play whenever the player zooms in or ADS but when the zoom goes away I can't get him to go back to the regular animation blueprint behaviors

[dry sleet]

I believe for things like that the choice is usually "Play Montage".

Montages stack on top of your existing ABP.

[heavy plinth]

I think I figured that part out actually. It ended up being that I needed to set the animation mode to animation bleuprint at the end of my break aim

I really appreciate the help

I'm still trying to figure out how to get the character to follow the crosshair when I'm aiming down the sights. As of now, when I ADS the character won't follow the camera's vertical movement

[dry sleet]

I still think it's worth looking into Montages :)

Will make it easier to combine animations such as crouch aiming, walking while aiming, etc.

But maybe for a later day!

[heavy plinth]

Yeah I think I've tried it out for my first cutscene but I didn't think to do that here. It's probably a lot more efficient

[simple thunder]

How can I make the material changes driven by this actor component immediately visible in the editor viewport without having to guess and click the function button in order to see them applied?

[hazy bramble]

Hello, how do I enable custom depth pass using the console command?

[frosty heron]

This is a custom component from some plugin?

[simple thunder]

an actor component I am putting together myself. Blueprints only

[frosty heron]

But that adjust material button you clicked, I never seen it.

Is that something that is added on latest version?

[simple thunder]

If you check Call in Editor in the function details panel you get the button

[dark drum]

BP only no as actor components don't have a construction script type event we can override. If adding the component to an actor, you could have the actor call the function from the component on the construction script but this would mean you can't just drop it onto any actor and have it work.

[dark drum]

Call in editor functions have been in for a few version now. They're pretty useful. 🙂

[frosty heron]

Pretty sure I know how to do this in cpp with PostEditChangeProperty

Don't know if you can in bp tho

[simple thunder]

What a pity. It looked like a clean way to add simple extra features with ease.
So another option to have non distructive material instance parameter changes on a static mesh actor basis could be to create an actual bp actor to drag and drop in the scene, bind an SM to it and control dynamic material instance parameters from there?

the goal here is to create the easiest possible way for arhcitects to adjust material offset and base color adjustments witohut messing with the original master material or material instances

[dark drum]

There might be a way using editor utilities BP. I've not used it but from my understanding, it allows you more control with this sorts of changes in the editor. It allows you to create you're own custom UI (editor only) for stuff as well.

[cerulean mango]

Hey, I have problems when I run my game in standalone with array not initialized which doesn't happen to me when I debug with the viewport, it's as if my initialization instructions didn't go fast enough in the initializing my gamemode. Is there a way for everything to be done step by step?

[dark drum]

Where is the array?

[cerulean mango]

@dark drum He's in the gamemode, but my gamemode calls all my spawners of my map to init this array

[dark drum]

Show you're code.

[cerulean mango]

@dark drum The first pic is what my gamemode is calling and the second and third one is what my spawner are doing ( sorry for the wire it's still my test environment , i didn't include all my spawners logic because it's really long).

FGM is my gamemode

@dark drum This is what i have in my viewport on simulating vs this what i have when i launch in standalone ( i'm suppose to be in front of a 3dmodel

[dark drum]

So the normal order things load is the game mode is created before things start to load in the level. This means when you use the get all actors of class node, what you're looking for don't exist yet.

When you play in the editor, the level is already loaded (assuming you're not using level streaming) which can give slightly different results.

You could probably just add a tick delay between begin play and the function you call.

[cerulean mango]

So right after the begin play i setup a short delay so everything has enough time to spawn and are ready to be setup correctly ( this is the first time i work with such a big map so i never had this issue ! Thanks @dark drum ! Everything works perfectly

[tiny sigil]

hello guys

i don't way my animation was sciding

[winged holly]

is there any way to save the result of a BlueprintPure function without using Variable ?
I want my node to be called once

something as temporary variable

[untold fossil]

check blend in times. If using blendspaces, check target weight interpolation speed

[thin panther]

No, the point of a pure node is exactly the opposite of that

[tiny sigil]

ohk

[winged holly]

@thin panther
yea but i want to store the result of that pure function, or what ever but not as a memver variable

[tiny sigil]

like wht was the best value you think

[untold fossil]

A pure function should only be used to **get **values (the result of passing variables through a function or retrieving private variables from outside an actor for example)

[thin panther]

Again, you don't have a choice, unless you're in a function

You want to store the result of something in the context of the graph. That is by definition a member

[untold fossil]

Setting non local variables inside a pure function is a very bad practice.

[winged holly]

can we make a pure function to non pure ?

[untold fossil]

Yes

Just uncheck pure

Then it becomes a regular function

[winged holly]

its not my function

[tiny sigil]

wixz ?

[untold fossil]

It depends on how fast you want the change in animation states to be. I usually opt for something towards 4 for my movement animation blend spaces. But something like 10 would work better for a snappy animation response.

[tiny sigil]

ohk

[untold fossil]

The higher, the faster

[tiny sigil]

ohhk🫡

[winged holly]

man i mean its native function from Engine like RandomRange and ...

[steady night]

hey i need help with a formula

so it always spawn in the arc depending on arrows

(doing a multishot obviously)

[obtuse mulch]

should be on the loop body

[steady night]

https://blueprintue.com/blueprint/gun9ncg3/

yeah well i know that part

its more

[obtuse mulch]

then using forward vector just add some rotation

[steady night]

how woul i constraint it to a -45/+45 degree angle

each time

[obtuse mulch]

clamp i guess

[steady night]

yeah but thats the formulathingi im looking for help with

how would i clamp it

or rather

depending on arrows lets say 6

needs to be divided with the -45/+45 angle

each time

somehow

[obtuse mulch]

ah ok let me think

[broken badge]

Anyone know what I'm missing here with data tables? Every tutorial I've double checked with shows that the blank headed column (A) in Excel should be hidden on import, but it always appears as "Row Name" for some reason...

(Not sure if there's a better room to ask this)

[storm swallow]

Hi! does anyone knows if SetFont in UE5 is working? because I want to create a text and set font/color on runtime and is not working for me L:(

I do this and I keep getting same Arial size 18 white

[steady night]

@obtuse mulch any ideas 😛

[obtuse mulch]

maybe this , but i dont have a chance to test

[steady night]

Ok i can test

[obtuse mulch]

but multishot arrows should be always even

wait ill send again, this one aint right

[obtuse mulch]

this better but still not 100% sure

[steady night]

okok

hm well it causes infinit loop

yeah cuz setting arros before loop and then extensing it

the eternal multishoot

epwpewpepwpepwwpewp

@obtuse mulch

[obtuse mulch]

ah yea

sec

like this?

[tight pollen]

hi

how show audio occlusion

i need debug it

because it is not working properly

[steady night]

@obtuse mulch works like a charm!

just had to add the character yaw roation also but yeah works

[dark drum]

Here's an alternative solution for you.

[steady night]

@dark drum thanks abit to late X ) but ill save it for later so i can se if it works elsewhere

[dark drum]

I don't believe the other method would give an even spread. And mine missed a bit haha

[steady night]

hehe

well ill try it also

[dark drum]

He's my version fixed. In case you need it. (Just needed to divide the spread angle by one less the number of shots)

[steady night]

perfect

[haughty snow]

is it really not possible to multi-select variables in a BP panel

[foggy sundial]

did you handle mixed blueprint and c++ defined components?

[trim matrix]

anyone able to help with saving variable to a save game object

when the player changes the audio sliders on the options menu I call this

which adds the new value their setting into the map overwriting the corrosponding value

However when I end session and start a new play session it seems the values some how have not actually been set

[broken badge]

How are you saving it to the save game blueprint?

[trim matrix]

I call across to my game instance a function which saves the save game object to a slot

[broken badge]

I presume you've already checked that SaveVolumePos is correctly calling the save function?

I can't actually see you setting the new map in the save game anywhere

[trim matrix]

yeah

there is a function that is called when the slider pos changes and the new value for that slider overwrites the value in the save game object

[broken badge]

Is it supposed to be automatically saving every time the slider moves?

[trim matrix]

so I was going to do that but then decided I set the values in the save game object and then the save game button does the save game to slot

unless I'm not understanding how it works

[broken badge]

At the moment, it looks like you're assigning the new variable with the Add node, but you aren't updating that in the save blueprint that I can see

[trim matrix]

would that not be the same

that Volumes data save game is the save game object I get the sound volumes from it and add to the map which overwrites the values in this case as designed

[broken badge]

No, so what you're doing at the moment seems to be:

• Loading the stored Map out of the save game
• Updating it to the new setting (locally).

And that's it. You aren't then saving the new variable back into your save game blueprint.

So every time you load the game, it's just going to reset to the default value

[trim matrix]

thats what the save game button does

[broken badge]

The SaveAudioSettings event?

[trim matrix]

the save audio settings event is called when the save settings button is pressed

feel like i'm doing stuff in wrong way here but not sure how

i'm doing what I believe is correct from what I've looked at online etc

[broken badge]

I feel like it's to do with the Add node, I don't think it's actually writing the new amount back into the save blueprint. Try dragging out from your VolumeSaveGame and use a Set node for the map instead of Add,

[trim matrix]

thats all I have when I look up Set

so I've also just tried removing the specific element and readding it obvs with new values

something isn't working right as I've just done a check where after pressing save button the values printed are those

which are wrong cause the slider for master is at 1.0 and player_SFX is near 0.0

actually thats correct image but still wrong, they are 1.0 and don't seem to change

[lofty rapids]

so your adding the volumes to a map ? are maps keys unique ?

so in theory if the key is the same, adding should update the the value ?

[trim matrix]

yeah

i'm bassically adding to the map with the keys matching what I'm wanting to update

my thinking and what the tip thing says is if a key already exists it will be overwriten rather then a new one being create

[lofty rapids]

makes sense

check the values before you save

pull out from the saved thing and try to print the values

[trim matrix]

well i've checked after saving and the screenshot for that is above

both values for both keys sit at 1.0

even though the value going through to the map isn't 1.0

[lofty rapids]

and what were they to begin with ?

1.0 ?

[trim matrix]

interesting

so what your seeing there is the bottom before save

and top after values save game to slot etc is all called

[lofty rapids]

so the value is updating, it's just not saving correctly ?

[trim matrix]

it's like they are being altered but when I go through calling the save to slot etc their being reset back to 1.0 which is the default for both values in the save game object

[trim matrix]

appears so

[lofty rapids]

are you using the right variable i see one says Data and one doesn't

[trim matrix]

Thats the save code

[trim matrix]

where sorry

[lofty rapids]

your isvalid says data in the name

idk why that would be just added

i feel like they are two different variables

[trim matrix]

it is correct

you mean that one

[lofty rapids]

ya is says VolumesDataSaveGame

the one you use other place doesn't say data

[trim matrix]

it's on the game instance thats why

the W_Menu has a ref to the save game object and the game instance has it's own ref to it

[wise ravine]

If I want to destroy an actor, but theres a possibility that the actor is not always in the level, how do I avoid an error message?

[lofty rapids]

isvalid

[trim matrix]

what I don't get is why the value is correct before the save to slot is done but after it's going back to 1.0

[lofty rapids]

ya thats a bit odd

[trim matrix]

up to this bit on the game instance things are okay

[wise ravine]

just like that right?

[lofty rapids]

looks legit

[wise ravine]

aight thanks

[spark steppe]

rightclick the current back train output pin, and click "convert to validated get"

that makes it a little more organized

[trim matrix]

is that code correct cause that seems to be where things are going wrong

[gray ingot]

Hi, i am working on save/load system for options widget, and when i save to slot, ue5 gives issue whet i am setting value MainVolume as "None", what can be the issue?

[trim matrix]

something your accessing is null void

you'll need to trace through until you find the thing that is null and then correct that

[gray ingot]

What could it be in this code?

I have set it in my SaveGameClass

[trim matrix]

it's your code so

[lofty rapids]

the erros usually say acces none trying to access whatever is empty

click on set main volume link in the error

[gray ingot]

It get's me to here

[lofty rapids]

save game here is empty most likely

[gray ingot]

But how if it makes sure it does exists

It is on event construct

[trim matrix]

this is frustrating me now on why when I do the save to slot thing it's giving me back same values

is this the right way to do it cause I've checked

everything up to that event in the game instance is correct

after it completed that event is when I do another check on the values and I seem to get the 1.0 for both keys

[wise ravine]

How do I make a script that 'fills up' this array randomly with different blueprints of my choosing?

[lofty rapids]

you want it to be at runtime ? or in editor, idk much about in editor haven't even tried it yet

[haughty snow]

if I have a bunch of all UPPERCASE strings, and i want to format them to be Capital Case, do I have to basically split the string into an array, to toLower on 0< index and then recombine?

[trim matrix]

out of interest are you able to even save to slot from the game instance ?

[lofty rapids]

makes sense, i would doubt thats a built in function

[haughty snow]

rip alright thats what i figured

maybe better to just change the original values in my package then to avoid unnecessary shit like that

ty

[lofty rapids]

a function could do the trick

since string manipulation can be slow i've heard, i would probably make it in c just to have be faster

[wise ravine]

at runtime

[trim matrix]

something defo not right

[haughty snow]

yeah im honestly just gonna change the original values to be the case i want, save time lol

[lofty rapids]

for one thing this array is classnames right ?

[trim matrix]

even when loading a new session the values for are their default 1.0

not what they were saved as in the last game session

[lofty rapids]

i save all my stuff manually so idk much about the save system

but its weird that your values print correctly, you save it, and the values are reset

[lofty rapids]

you want to create a list of class names ? you may want to use a list of all that can be used, and then keep getting randoms from it, will there multiple of same class name ?

[trim matrix]

Anyone know why this would be happening right ?

if I add a break point the break point never gets hit

the flow is running though if I put a print string for instance

[lofty rapids]

i usually trust a print string over break point

[wise ravine]

I want to get a collection of BP_Stations and randomly fill up the array with them at runtime
E.g.

1. BP_Station6
2. BP_Station2
3. BP_Station1
4. BP_Station6

[trim matrix]

well i'm trying to get this issue fixed with the save thing

[lofty rapids]

so there can be multiples of the same one ?

[trim matrix]

I've narrowed it down to regardless if I've saved on previous play session this seems to always load the default values for the map

[wise ravine]

yes

Or would it be easier to set the stations (array values) in the editor and then just use random int in range?

[lofty rapids]

like i mentioned, create an array with all the ones available, then just pull random ones from it in a loop to create the new array

[lofty rapids]

ya you could have just the list and pull randoms, either way you would probably need a list of available stations

that you can pull from

[wise ravine]

okay

[lofty rapids]

and your printing in this part those values and they are incorrect ?

[wise ravine]

There is one thing actually, I want repeats of 1 type of station (the default station) but not repeats of the other types

how would I do that?

[trim matrix]

so the values are correct

[wise ravine]

Could i not include that 'default station' in the array, and then randomly select between using the array and just a variable with that default station, would that work?

[trim matrix]

it's when the new play session is done the values reset back to the default 1.0 rather then the saved values which are pulled in that screenshot above

[lofty rapids]

you could also have a temp array that you pull from, and if you pull that class remove it from the array, so the next pulls won't have it, i only say temp array because you want it to be there afterward for the next pull

maybe even a local array that is in the function that is all the ones you want to pull from

so it resets when you run it again

[wise ravine]

I see

hmm

I'll try that, thank you

[lofty rapids]

but you don't want to remove while looping

so thats a problem, you can also use a count variable

but that involves checking each one and the count

where you would have another map of your max counts

and if that class was in there that amount of times then goto next one

but that will make the list different sizes which you would have to probably compensate for

so it's a little tough to do

[trim matrix]

Blue is values when saved from the map within the save game object

[high iris]

Say I'm grabbing physics objects in the world. Is there any benefit for me to dynamicyally create and delete the physics handle when I do, or can I just keep the Physics Handle Component on my player character actor and use it when convenient? I ran into this blueprint that someone recommended, where the dev dynamically creates / deletes the component, and I'm not sure if this is somehow a better approach?

In the past I'd just leave components on the player actor and not bother creating and destroying them.

[trim matrix]

I've noticed a odd

when I've changing the volume slider for Player SFX the master volume is showing

[lofty rapids]

so your save is actually working, it's resetting somewhere else ?

[trim matrix]

I might be tracing it down cause when I move player SFX slider obvs I shouldn't be getting master volume

[haughty snow]

ugly but she works lol

[trim matrix]

so question is why am I

[haughty snow]

gotta wait for my c++ eng to wake up to change the actual package but wanted to see if this would actually work

[wise ravine]

Is there a node that checks whether an integer is even or odd?

[thin panther]

Modulo it by 2

[trim matrix]

this don't make sense as to why I've getting Master_Volume being passed through

[thin panther]

if the result is 0, it's even, if it's 1, it's odd

[trim matrix]

when going into this function i'm passing Player_SFX

[lofty rapids]

so you only want to uppercase the first word ?

[haughty snow]

letter

i have a bunch of STRINGS but i want a String

[trim matrix]

this is actually getting me vexed now, how am I getting something different being passed through to what I'm actually doing

[lofty rapids]

this just lowercases the first word ? where is the capitalize part ?

[haughty snow]

it lowercases the entire word besides the first letter

[trim matrix]

So blue is after saved

[haughty snow]

if the index is 0, i just add it as-is to the temp array since it's already capitalized

the rest i do toLower

[trim matrix]

orange is when i've stopped and started play session

is this right, only other thing I could think is causing issue

ignore the logic in middle but the map on left and the values of it on right is that all correct for it to be correctly set etc

can you even set values that are on a save game object from outside of the save game object or does it need to be done on the save game object ?

[gray ingot]

So, i figured my Async Load Game from Slot gives me bool type named "Success" = "false", what does it mean?

[lofty rapids]

heres one way without a loop
https://blueprintue.com/blueprint/0om6njmr/

theres an extra to lower in it, but it's just to show how i would go about it then you wouldn't have to worry how the sentence was formed it would just lowercase and uppercase the first word

[haughty snow]

ooooooo this is nice thank you!

[wise ravine]

This should work right? Assuming index 0 on the array is the default station

[hexed bane]

i dont know where to ask, but did anyone know a great tutorial to make a gun system? I found MizzoFrizzo, but dont know where to start. and yes, i not new at developping, im a old Unity user

[lofty rapids]

what are you trying to do here ?

if it's even set it to zero ?

and your resetting anomoly# ?

[trim matrix]

finally i have got it working

I know know the issue

[wise ravine]

I forgot something. basically I'm trying to randomly switch between spawning the default station and any of the others

[trim matrix]

rather then doing the value alteration on the specific key I was finding the key and adding that was messing up the flow

now because I make the change to the map to the specific key at the point it finds the matching key from the one currently being looked at it's loading and saving fine

[dusky cobalt]

I need to spawn 500 actors, but it's crashing my engine. Is it possible to put some kind of delay inside function, so every 20 actors there is a small delay? Or how would I start optimizing something like that? Or If it cannot spawn 500 actors then my whole function is bad?

[lofty rapids]

are you using a loop ? and what is the error ?

[dusky cobalt]

Yes, not really errror, just it lags and level doesn't start

The loop is quite heavy, i'm trying to put some of it's parts to be calculated once

This is the loop, it ''creates'' location for each cell size.

and then what is making lagg is probably the fact, that every cell is shoting line trace by channel

and then if it hits ground, it gets location, and if Z <1 then it's places itself on that location

Made it a little bit easier to read, sorry for mess

If it's not possible I will try other approach to create grid but I need to populate huge landscape and will probably need to spawn thousands of these

[lofty rapids]

so your making a grid and linetracing, and dropping the grid cells if the hit is below a certain height

whats grid size here ?

[dusky cobalt]

Grid size is like the Whole Array Size 10x10 for example

[lofty rapids]

right but if it's a big number you'll get way more performance in c++

loops are just slow in bp

and if you got a huge grid it's just a tragedy

[dusky cobalt]

I need to spawn like 60000 elements lol xD

[lofty rapids]

ya thats just asking for c

but it works on a small grid right ?

[dusky cobalt]

but do you think C++ will handle that?

yes, it works

[lofty rapids]

and on a large grid it says infinite loop ?

[dusky cobalt]

No, it just loads, loads and boom game is not playing

[lofty rapids]

when you close it, it's not throwing any errors ?

[dusky cobalt]

I deleted line trace and it spawned 10k elements now

[lofty rapids]

i'm suprised the line trace is heavy like that

i thought it was a pretty lightweight feature

[dusky cobalt]

yeah, now it spawned 20k after like 20seconds

[lofty rapids]

right you'll notice a significant boost with c++

and it will handle it, worse thing that will happen it will hang like that

but bp usually craps out i'm surprised it's hanging

[dusky cobalt]

After the actors are spawned and if they are just spheres, they will cause perfomance issues ? If I have like 30k small actors on the map?

[lofty rapids]

https://tryitands.ee/

[lofty rapids]

did you up your max iterations ? so that it would go that high ?

[wise ravine]

What does stream do? 🤔

[dark drum]

A 'Stream' is a way of having random but deterministic number through the use of a seed.

[wise ravine]

ahhh right

interesting

[dusky cobalt]

I didn''t change anything but you can see grid is populated here. Maybe if I there was a way to spawn them before the game starts it would be better.

[wise ravine]

wait so does a 'Random int in range' without a stream use the same stream/seed every time it executes?

2. and If I were to input seed 5 for example, does that mean that the numbers generated will always be in the same order? (unless i change the seed)

[dark drum]

You have to connect a stream, and yes, if the seed is the same, it will pull the same set of numbers in order. (assuming you don't reset the stream)

[dark drum]

What does the 'BP Grid Cell' do?

[wise ravine]

I mean for this node, does it use a stream?

[dusky cobalt]

and has events on overlap but I guess these don't work until they are started

[dark drum]

I don't believe so.

[maiden wadi]

Yes. It gets any scene component whether it was added on a C++ class or BP class and copies them and their attachment hierarchy. Then I just iterated over them to set their materials to a see through kind of preview ghost.

[dark drum]

What's there purpose? I can see your setting the scale and material but why?

[dusky cobalt]

The purpose of cell?

[dark drum]

Yes.

[dusky cobalt]

So basically I want it later to hold some informations like what is the type of cell, if it's empty etc. so then I can let player do something on some cells and not allow on others.

[dark drum]

Personally, I wouldn't be spawning 10's of thousands of actors for this. Actors can be pretty heavy to be used as just data containers. It sounds like you'd probably want to use uobjects. Create one for each grid section and store it in an array or a map.

[maiden wadi]

Depending on the case, even multiple maps of FIntPoint to Data can be better in a TMap

[dusky cobalt]

I'm still brainstorming that. I have 1 more approach to test with creating grid, but I just need easy clean access to each tile so I can set it's type, and also let's player even click on it so they get to see tooltips etc for each tile.
By Create one for each grid section, do you mean that instead of spawning ''cell'' actor, I just spawn UObject instead?

[dark drum]

uobjects don't exist in the world so you construct them as apposed to spawning them. When dealing with this sort of scale, you need to try keep things as data and then use static mesh instances to display it appropriately. You can then spawn actors based on proximity if needed to allow specific functionality.

The uobject would act as the data container that you would have a manager type class query when needed.

[hearty tartan]

Hello everyone, i'd like to open a webbrower page from the game, and retrieve a json response ( it's for an authentication ), i've seen un blue print that i can use "open url" and what to use to wait the answer ?

[dusky cobalt]

Can I create UObjects with blueprints? It's this one?

[dark drum]

The top one. 'Object' As an FYI, it's pretty bare bones.

[dusky cobalt]

Ok I see Construct as well. Can I treat it as Cell Actor I had before, just different ''type'' of actor? But it can hold the same logic and is lighter?

It would be cool to use these UObjects and spawn them, and they would hold DA_Cell (Data Asset), and then they would randomly choose from array of Data Assets if it's DA_ResourceCell or DA_TerrainCell, could generate some cool things I guess.

[merry chasm]

hi guys.
I render with mrq, deferred rendering,4k, 16 temporal, 10 spatial.
What is this ghosting? How can I reduce this?

License plate ghosting

[dark drum]

No, you can't treat them as just an actor unfortunatly. They don't have any context to the world so they are limited in what they have access too.

As an FYI, my machine can handle just over 7k actors before the frames dip to around 30 fps and that's with 16 cores at 3.5ghz. That is will collision, (which was you're intended use) I can have about 21K with no collision.

[faint pasture]

That looks damn good

the only thing that makes me think it's cgi is the road

[hoary ore]

Would it be more flexible to make "activation logic" using an actor component's even graph, function library, or something else?

Example: I have a door blueprint, a light blueprint, and a lever blueprint. I want to line trace to them and trigger their appropriate animations/movement when I press a specific interact key. I don't want to redo the triggering logic for every type of item like this.

[onyx gull]

why is this code removing a different element than the one it returns?

I've tried it without the local variables as well, that was actually the first way I tried it, and the local vars were an attempt at a fix

[lofty rapids]

you can try to cache the random value

[dawn gazelle]

Pure nodes execute each time you pull a value from them.

[onyx gull]

that's what I was trying to do with the local variables

[lofty rapids]

so pull from that the other two times you use it

i c it's already there lol

[faint pasture]

because random is pure, it's getting rolled twice

just remove the saved one, not another random one

[onyx gull]

fixed, thank you

[faint pasture]

But it looks a lot cleaner to just use the variable get nodes instead of dragging pins all over

[faint pasture]

makes it more explicit too

Set Out

Remove Out from array

return Out

[dawn gazelle]

Just a heads up too, this won't work as you expect if the input boolof the function is false.

You'd need to set the value before the branch

[wise ravine]

how would I repopulate an array at runtime?

[dawn gazelle]

Set the array with values

If your array is something that isn't object based, you can have a "Default" array that you don't touch but use only to SET back into an array that you do modify.

[wise ravine]

how would i randomize the repopulation or 'shuffle' the items in an array?

[dawn gazelle]

There is a "Shuffle" command you can run on an array.

[wise ravine]

oh sick

I'll have to try that

wait no that still doesn't solve my issue

[faint pasture]

What is your actual issue, what is the final end result you're after?

[wise ravine]

nvm I think I'll figure it out

[faint pasture]

You have an array of things. You want what from it?

[wise ravine]

Basically each item in the array is a level, and there are 2 types. 1 is the default level, and the 2nd type has some type of anomaly. There are multiple BP's of the 2nd type. Rn I have a script that randomly shuffles between an array of the 2nd type. However I realized I want a sort of difficulty system, where as the player progresses through the # of levels each level gets more 'eerie' (this is for a horror game)

So I think I'll just have to make a bunch of arrays manually without randomization

to achieve that result

[wise ravine]

^

There's nothing wrong with the code (that i know of) I just might want to change the goal of the script

[trim matrix]

im confused

[dawn gazelle]

Random Bool

You can even do "Random Bool with Weight" if you want it to be true more or less often.

[quiet pasture]

Does anyone know how to get world settings in BP? There's a node in UWorld, but no way to get it from.

[wise ravine]

really? Thats a big help actually

that cleared a lot of code. thanks 😄

[trim matrix]

i tried to set text but its still not showing

[wise ravine]

is there a node that gets multiple items from an array? or do I just have to use multiple Get nodes

[dusky cobalt]

For Each loop

[lofty rapids]

whats actually happening, and what is it supposed to do ?

[trim matrix]

i want it to have this other widget pop up when the player dosnt have enough stars, telling them how many they need still, but it dosnt do that, and the set text thing just dosnt show as an option in my event graph

[lofty rapids]

did you create the other one and promote to variable ?

[trim matrix]

yea

[lofty rapids]

so that you can use it

are you adding it to the viewport based on a bool

show the code

[wise ravine]

just like that?

[trim matrix]

this is where im at

[dusky cobalt]

Just use normal For Each node, and put the number of Last Index to be the last item of array you want, so like from 0 to 3 for example will take all items from array from 0 and 1.

[dawn gazelle]

Are you trying to append your array, (ie. keep current items, but add several more) or are you wanting to overwrite your array with the contents of another array?

[wise ravine]

overwrite

[dawn gazelle]

Then just do a "Set" of that array with the other array.

[dusky cobalt]

Try to rewrite all the steps that you want to happen into a generic language. First understand clearly what you want to happen step by step, and then try to change this into code. I know the blueprints can look messy, but there is happening too much for sure.

[wise ravine]

I would but I only want a limited number of the items in the other array

The 'total stations' array has every possible station

im just using it to store info basically

[trim matrix]

huh?

[dawn gazelle]

If you're trying to randomize things, then you could still set it, shuffle, then resize it to the size you want.

[wise ravine]

So lets say I only want 7 items from the 'Total stations' array, how would I do that? Should i still use a 'for each loop'?

[wise ravine]

I was gonna shuffle the items after

2 randomizations

[dusky cobalt]

How are you calling that function to happen?

[wise ravine]

this 1 ^ to ranomdize which stations im getting from the total, and a shuffle to shuffle the order

[lofty rapids]

so it looks like you have another reference i'm guessing i'm thats the new widget you want to show and you have created it somewhere like begin play

[wise ravine]

actually nvm i dont need the 2nd one

it should already be randomized

[trim matrix]

yea

[royal vale]

Hey Yall!
I have an issue with overlap checking.

I have a mesh actor that grows it's scale via a timeline , while that actor is growing I want to check if it overlaps a player.
The issue is that it only triggers the overlap if the overlapping player is moving , it will not trigger if the overlapping player is standing still.

Here's the code , and a video example. I know a workaround is to just slightly move the player back and forth via tick and location set and the overlap will work fine but I think that will present future issues.

Any one know why this happening or how to fix it?

[lofty rapids]

so you want it to appear when ?

[trim matrix]

when the player hits the doors box collsion im using as a trigger, but i dont want this one to freeze the player

i got the ui to appear now, but it dosnt go away when i leave the trigger

and the text binding isnt setup correctly, but its showing now

[dusky cobalt]

If you want to remove widget on overlap end, just get that widget and call Remove From Parent

[wise ravine]

ohhh sick

so does the resize node simply remove the unwanted items form the array?

[trim matrix]

ok yea i forgot ab that lol
