blueprint

[jaunty solstice]

Thanks. yeah it was a scene component!

[vernal snow]

Hiya everyone, just trying to figure out if my current method of getting the player a weapon is good.

So for context its a weapon system taking inspiration from Call of duty, mainly the element of modding said weapons.
So currently i got a few bp types and just gonna go order.

Currently through a prototype got the Meshes to change and all that depending what is added via structures and datatables etc etc so nothing to worry about there for now.

BP_PickUPMaster > Adds a Skeletal Mesh Component Related to its weapon type (Firearm SKM / Throwable SKM etc) > Spawn BP_Actor_WeaponMaster which gets attached to the player.

So it adds a Skeletal Mesh Comp to the player its intention is to add in input to the player.
This SKComp adds a Actor which is the visual component and has varied data structures and the functionality which is referenced by the SKComp.

Not too sure if i explained the process correctly, or if it can really be answered, so far i got it where it works and attaches to the player.
But im still new UE5 i'd say so i might be missing a type of actor that can do all of this, i thought a Skeletal Mesh Actor might be a good attempt but it kinda bugs out when the Skeletal Mesh asset doesnt have anything in by default.

[lofty rapids]

i feel like it might reset

[lunar sleet]

prly a lot easier to not destroy it in the first place

[sick sky]

random thought :

does it "cost" less to UE to cast from A to B if there is "less in between classes" ?

for example
casting scenario 1 :
Actor to Character

casting scenario 2 :
Pawn to Character

is it equal in performance cost ?

[gentle urchin]

The cost depends on :

• is it already loaded?
• If no:
• how big is it
• what dependencies does it have
• what else must be loaded with this
• if yes
  • Move On

[hollow pond]

I'm trying to add breakpoints to nodes in a level blueprint, but when I switch levels, the breakpoints disappear. is that normal?

[sick sky]

its interesting, but it doesnt really answer the question

[gentle urchin]

It does

Number of classes doesnt matter

[sick sky]

okay

[gentle urchin]

Size and dependency does

[sick sky]

so if a class is a child of child of child of child of another class, it has a bigger dependency ?

[gentle urchin]

If MyPawn is a straight subclass of APawn with nothing new, their casting cost is ~Equal

[sick sky]

okay

[gentle urchin]

Only if you introduce dependencies

And/or assets

[sick sky]

what is a dependency in this case ?

actor components and stuff ?

[gentle urchin]

Hard references to other stuff

[sick sky]

okay

[gentle urchin]

If your GreatGrandPawn has a hard ref to BP_SuperBoss

Then BP_SuperBoss is also loaded

Along with its BP_SuperHammer and whatnot

You can right click any asset in the content browser and chevk the reference viewer

You can also check the size map of the asset

[lofty rapids]

yes because the level blueprint is only for that level

[gentle urchin]

Gives you some hints to whats going on

[sick sky]

okay ty

its interesting

[gentle urchin]

So when you cast

[sick sky]

i try to avoid that

[gentle urchin]

You want to cast as high up as possible

[sick sky]

usually when i have to cast, its to generic classes like Pawn

[gentle urchin]

Thats good

[sick sky]

i use 99% of the time interfaces when working on communication

[gentle urchin]

You can generally cast to player related classes as they're almost guaranteed to be loaded anyways

So the cast would be free

[sick sky]

true

wait thats great

[queen dagger]

im wondering why my button doesnt have an events category so i can put an on click function

[sick sky]

so casting to player isnt that much costy

[hollow pond]

yeah, but I mean that I create breakpoints in a level BP, switch to another level to start the game, then when I load the first level again, my breakpoints don't fire. open up that first level in editor again, the breakpoints have disappeared

[sick sky]

i thought that each time it was doing some hard work

[gentle urchin]

If its already loaded, no

[lofty rapids]

try to compile or save

[sick sky]

you are selecting the textblock

:)

[queen dagger]

still isnt showing

[sick sky]

set to is var

i tested and when disabling the events disapear

[lofty rapids]

interesting i just dragged a button in and it had the events

[queen dagger]

ohhhh

interesting

[sick sky]

by default "is var" is to true

[queen dagger]

would have never thought it had to be var

[sick sky]

untick and see the "events" tab disapear

[sick sky]

its kinda logic because basically those events are event dispatchers

[ancient heath]

Make it Variable

[queen dagger]

gotcha works now

thanks

and second question

probs a bit more tricky

[sick sky]

other random question :
is there something faster than another between :

• searching for <> by class
• searching for <> by tag
• searching for <> by interface

[queen dagger]

but ive gotten to the point where i want to have multiple players play so i need to spawn in characters that have seperate controllers where would i start on that

[lofty rapids]

i would hope behind the scenes that getting actors with tag would be a bit faster, because you would need only get all actors with tags, if they don't have tags np

[gentle urchin]

Its slower afaik

[lofty rapids]

#multiplayer

[lofty rapids]

interesting

[twin shale]

This is exactly what I needed to know, thank you. I realize I'm not architecting this data the "best" way but the alternative is lots and lots of code, checks, validations, and more work to make simple items. The way I'm doing it currently is far easier to use but that has a trade-off. I think I can live with this trade-off for the benefits I gain

[gentle urchin]

Its always a tradeoff

Storage/performance/memory

[little coral]

i am trying to keep track of the score, total noob so expect things being plugged to the wrong hole every now and then

Doing blueprints with gemini has no the been the easiest excersise

what is it that i should be doing ?

[lofty rapids]

i'm guessing it doesn't work ?

trying to play all these timelines on tick is probably not a good idea

[faint pasture]

Why is score something that's being handled on tick or timeline to begin with?

What are the broad strokes of what you're trying to implement?

When XXX happens, you want xxx and xxxxxx to happen.

[little coral]

its a rail shooter setup, bassically i have 4 locations on the map once the score reaches a threshold, move the player from the origin point to point 1, and on each threshold move to the next taregt point with each movement also a rotation, since the camera is looking at a certain part of the environment where the targets are laid out

[faint pasture]

OK so break it down.
Start with the movement part.
Event MoveToNextPoint

THAT will want a timeline or tick involved

timeline can work if you want to author it like:

Begin play -> ??? -> timeline -> ??? -> timeline ->??? timeline
if you want it to be more data-driven then you'd use tick

[little coral]

i am just relying on event tick because of the score, and becaue the whole experience is just this rail track so its not that expensive in the grand scheme of things

[austere ferry]

I would like to use Unreal Engine’s DataTable to animate. In the CSV, I have columns for Frame and Value. Could you advise on how to set the rotation value of a specified actor to 1 when it’s at frame 1? I’ve set up the nodes as shown in an image, but it’s not working properly.

[faint pasture]

OK so I'd set it up like this if you wanted to use tick for everything.

Tick -> interpolate CurrentTransform towards TargetTransform -> update Score -> did score cross some threshold? -> update TargetTransform

that'll be a catch all

"Each frame, move towards TargetTransform, update score, and set a new TargetTransform if some criteria is reached."

if you're already at TargetTransform, moving towards it won't do anything

[little coral]

hmm, i am gonna try that now and see what happen !
appreciate the insights

[lofty rapids]

wdym "rotation value" set to "1" ?

[austere ferry]

Thank you for your comment. I would like the first frame to have a rotation value of "1", and for the second frame, to update the rotation value to "2". The information to be updated is in the Datatable.

[lofty rapids]

frame as in in the foreach ?

i'm not understanding where you are saying "frames" ?

you have some data with a fram, and value

so in your loop

each one will be that value

[austere ferry]

I have managed to load the CSV. Currently, I am updating the "RoName" and changing the value in "AddLocalRotation", but it's happening too quickly.

[lofty rapids]

right thats typical foreach runs in one tick

[austere ferry]

Would it be good to add a delay after the Foreach loop? I have a feeling it might not be the best idea...

[lofty rapids]

maybe a timer

[little coral]

@lofty rapids is this what you meant ?
it is moving the camera from point A to point B but rotation is not being affected

[lofty rapids]

i mean the point is the indexes could be out of bounds

but i was specifically talking about where you +1 and + 2, 3

to the index

but either way you don't if it's valid

but don't try to do all that on tick

it won't work like that

[little coral]

So what sort of event should begin all this ? just a regular event begin play ?

[lofty rapids]

i would probably make it a custom event, when do you want it to fire in a sequence, then fire again ?

you can make use of timeline finished to make them not all run at once i think

[little coral]

imma try then

is there a better way to add to the index and ensure it is within bounds ?

[lofty rapids]

you can clamp it

but in general you don't want to add a bunch to the index and use it

when it gets to the end your out of bounds

[steady night]

hey

the Gun aint playing the animation montage

tips on whats going wrong ?

[lofty rapids]

you got a slot in the animation bp ?

[steady night]

yeah

if u use the "play animation" it works

but not montage.

the 2nd montage works the "arms" wich is the parent

[lofty rapids]

maybe #animation might know better

[steady night]

this is just some ssilly problem

zzZZ

i mean this works -.-'

[graceful peak]

Not really sure what a good channel to ask this in is...butttt i had an idea for an interesting mechanic. Basically, it's an effect that's in superliminal but in reverse. But if you watch the video attached, I want to project a 3D object onto a 2D surface, such that you can't even tell that the 3D object dissapeared until the player moves and looks at the wall from another perspective. I managed to figure out the math to get the scale of the 2D project right, butttt rotation and perspective distortion seem pretty impossible to handle here. Just wondering if anyone has any ideas.

[bold cypress]

I need to change the orient rotation on movement for a mob, but the details for movement aren't showing up. Do i need to remake it or is there a fix?

[lofty rapids]

5.3 ?

[steady night]

am i thinking wrong ?

i want it to spawn at "muzzle location with the same rotation as the socket?

but idnno if it working

the Red arrow would be "Forward" Right ?

[bold cypress]

If you are asking me then yes

[lofty rapids]

ya if your details panel is completely gone you'll most likely need to remake it

or revert to a backup

i have seen this a bunch in 5.3, i have not had the problem yet

[bold cypress]

Its happened to me a few times already, but this is the first time its actually been a problem.

[little coral]

is there a cache that needs to be purged when target points get moved around in the map ? for some reason it moves to a position where nothing is at sometimes

[lofty rapids]

when do you popuplate the array ? on begin play or something ?

i can only imagine for some reason the target points array isn't getting changed but it could be anything

[bold cypress]

It seems like it has to do with the c++ editor. Everytime i see something that has the issue it will always be editable in c++

[little coral]

I am still doing it with event tick, nothing else moves things

[lofty rapids]

if you do a custom event instead

you can run it when you press a button to check it

create a custom event

instead of tick, go from the event into all the stuff

then you can call it whenever you want

but i think you probably want finished right ? you want them to run one after another ?

right now performance wise it doesn't look to good

right now if gamescore >= that get, it will start running all those on update idk how timelines would handle that i'm still learning

[little coral]

Yeah had that issue before it ran entirely or didn't run at all between custom event and begin play

[little coral]

Will try that as well

[lofty rapids]

if you make a custom event

and run that event on tick it's basically the same thing

[lofty rapids]

are you wanted to run one after or another, or change on score ?

[sonic fossil]

Hello! I have a very, VERY strange bug here. Can I ask for some help here that is related to UMG ?

[little coral]

On Score x move to point a and rotate and so on

[sonic fossil]

Oh just saw the UMG section, sorry about that

[lofty rapids]

so when you score hits a certain number, you want to move to a point ?

but your using timeline so your trying to move smoothly or something ?

first thing i would do is i usually have two functions change score, and show score

there you can use change score to check the score if its a certain value run an event

but i would have an array of booleans for each section

i would also link the rotation and location arrays by index

might be tricky to keep in order but if done right you can store multiple values based on an index

[little coral]

Exactly

[lofty rapids]

start with triggering an event when the score reaches a certain point

i would suggest making it low so you can test it quicker

i wouldn't be using tick

use an on change kind of event or function

then you could have an event where you pass it the index and it runs the timeline

i'm sure there is several ways to do it as there usual is

also structs exist but ig in bp they are broken so you should make them in c++

i have not done that yet

i have a struct and it works fine so far but i just made it and forgot about it

[hot lion]

Hello there, when i'm trying to test a collider event, or a line check it always work the first time but it detect somehow the same actor again the next frame and for some reason it dosen't consider it to be the same, any idea what could be the cause ?

literally not moving so hitting the same actor

[lofty rapids]

it's != so it's going to false like it should ?

the first time it's != is true and it sets it

next time it's false

but is it not the same actor or something ?

[hot lion]

huh yeah, i'm beeing stupid there, so the mistake lies elsewhere 😒 huh

[bitter star]

Hi guys, I' working on a BP to use a box collision to trigger a change in value on a material and I m getting an error pointing to the last node in the event graph. Do you know why?

[hot lion]

Nah yeah I got it. Thanks for the headsup, helped a lot my stupid brain

[queen dagger]

ok so is there a way to identify which sprites to use based on which character is chosen? like for instance i have a character with its base animation state, however if we select a different character is there a way to transition to using those sprites instead without needing to create a whole new child character with a new anim source and anim blueprint

[faint pasture]

sprites would be data on the data only character bp or in the data asset or in the row in the data table

A common pattern is to:
BaseCharacter
Ben
George
Judy
Where all the subclasses are data only

[queen dagger]

correct

[faint pasture]

but you can just as easily set values in an instance of BaseCharacter from a data asset or data table row

up to you

[queen dagger]

data table?

[faint pasture]

I like seeing them in 3d so I like to use blueprints AS data assets, so to speak

[tranquil lagoon]

I am having a very hard logical problem I would like help with solving.
I am trying to make a Breath of the Wild type Cooking System where players can enter any ingredients and the game would try and find the matching one to a list of recipes

How it works, is that:

1. I have a data table with recipes, inside each row is an arrays structs (RecipeIngredients) that keep a Resource type (Enum) and an Amount (Int)
2. I have an actor (CraftingTable) with an overlap, it contains 4 struct variables of type S_Recipe_Requirements (StoneAmount, WoodAmount, FoodAmount and SkinAmount)
3. Each time an item gets overlapped on the table, it will check and increment the corresponding variables amount by 1

I got this far along, this is where I get stuck
The problem I have now, is how would I build the logic where the player can put in any amount of items (recipes won't be longer than 4 structs) and the actor will find the correct corresponding recipe. I believe I should be using For Each loops to compare, but I am not exactly sure how that would work.

How would you approach this problem?

[livid axle]

Hello, I am trying to get a character to summon some mobs around him with EQS, but for some reason it just returns an empty array even though in game with the debugger I see it manages to find locations. Am I misunderstanding how this should work?

[faint pasture]

Loop over all data table rows, selecting the first recipe that the ingredients meet the criteria to

[languid wolf]

Hey, did you manage to solve the issue?

[faint pasture]

Assuming you have the foreach row bit:
For each row -> bool = true -> for each IngredientType -> bool = bool AND do you have enough of that ingredient on hand?
-> finished -> no recipe matches -> finished -> if bool -> this row is the recipe

[tranquil lagoon]

Yes I understand thats what I need to do, but its how it would look like that is the problem, I got this far and then realised I am probably doing it the wrong way since this seems highly ineficient to check all the different material types in each possible array slot to find the correct combination

[faint pasture]

It'll be 3 loops deep

for each recipe -> for each ingredient in recipe -> for each ingredient on hand

it'll perform better at an extreme scale with maps but it's the same idea

you choose the recipe where for each ingredient in the recipe, you have enough of that ingredient on hand

then you remove those ingredients and replace with the item or whatever

Make functions

CanMakeRecipeWithIngredientsOnHand, CraftRecipe, etc

stuff like that

if you want

it won't perform any better but it might be more easily tested and reasoned about

[queen dagger]

ok so

this is the senario

i have a bunch of jump nodes that are named character specific

i have the parent character

currently hard coded to a specific character is there a way to change this based off a character selection?

[lofty rapids]

jump to node is a plugin thing you are using ?

or it's a built in function ?

or you created it ?

[queen dagger]

plugin

it basically just a break where it forces an animation to play

but for instance theres a jump animation

[lofty rapids]

how do you have it "hard coded" ? in the target ?

[queen dagger]

but like 26 of them depending on the character

the parent character is currently set to narutos jump as thats just a place holder

[faint pasture]

don't talk to animation from code whatever the equivelent of "play montage" would be

[queen dagger]

?

[faint pasture]

IDK anything about Paper but the general form is that the animation READS state, it is not written to

[faint pasture]

The skeletal animation version of that would be the animBP noticing that the bool bIsInAir is now true and it'll switch its state machine from walking to falling with a jump animation transition

[queen dagger]

yes

[faint pasture]

animation knows about gameplay code
gameplay code does not know about the animation

[queen dagger]

jump to node is just the code to force a transition to a state

[faint pasture]

yes that should be RESPONDING to the pawn state, not told what to do

unless that's some unavoidable thing

[faint pasture]

does the state machine have node names that are character specific?

are you making 1 state machine per character?

or just 1 with the sprites as data

[queen dagger]

yes

so lol

[faint pasture]

why

[queen dagger]

i have one complete state machine

[faint pasture]

I mean do they all do the same thing or are they very different

[queen dagger]

and i am wondering if there is a way to do it without having to make multiple of them

the only difference right now is character sprites

[faint pasture]

There certainly is normally but like I said you're like the 1 person who uses Paper so it might be different

[queen dagger]

lol fair enough

[faint pasture]

instead of "Play HeroCharacter#2JumpAnimation" it'd be "Play MyJumpAnimation"

and MyJumpAnimation is just data, it's just a variable you can set somewhere

[queen dagger]

ok im sorta tracking

so in the character bp

i should assign a character variable

based off that variable itll load the sprites that pertain to that character

from a repository of some sort

[tranquil lagoon]

I think I get this, but currently all my ingredients at hand are just 4 seperate variables, should I put them in an array?

So it's like this?

[faint pasture]

what is the structure of S Recipe Requirement

[tranquil lagoon]

Resource type and amount

[faint pasture]

That's kinda redundant, I'd just have an array of ResourceRequirements

WoodAmount:
enum = Wood

bit redundant

Just have an array like:
Requirements:
Wood, 3
Stone, 12
Bananas, 43 //you can do this now as you can just have any old thing

in fact those probably shouldn't be an enum, but an FName or GameplayTag, but enum will work for now

What's the structure of S RecipeInfo?

[tranquil lagoon]

Sorry for asking so many dumb questions but I am relatively new to this.

[faint pasture]

no problem

[faint pasture]

ok I got you, yes this should be an array

an array of RecipeIngredients just like in the RecipeInfo

Array <RecipeIngredients> IngredientsOnHand

you'll probably later want to lose the recipe language and just make them items but it'll do for now

[tranquil lagoon]

Okay so on the CraftingTable actor I just created an array called IngredientsAtHand with 4 indexes (one for each type)

[faint pasture]

The simplest item system would just be
Array<ItemStruct> BackpackInventory
Array<ItemStruct> CookingInventory

ItemStruct:
Icon
Name
Count

And a RecipeInfo would just have its required items

[faint pasture]

nah, use an array of RecipeIngredients

instead of blindly adding, make an add function or event that can check if there's already one with matching enum (or tag or FName), and just add the count to it

[tranquil lagoon]

RecipeIngredients is not a structure, it's just what I named it. It's an S_Recipe_Requirements

[faint pasture]

whatever this array is

hell just call it item

[tranquil lagoon]

Yes, that is what i created

It's the same!

[faint pasture]

then later you can have recipes like

Sword + FirePotion = FireSword

or whatever you want

[faint pasture]

yes, S_RecipeRequirements is what you want an array of in S_RecipeInfo AND in your crafting table

[tranquil lagoon]

Yes! That's what I have now

[faint pasture]

TArray<S_RecipeRequirements> IngredientsOnHand

probably rename it but good luck renaming BP struct, have a backup lol

[tranquil lagoon]

😭

I am on source control

[faint pasture]

aight then yolo

[tranquil lagoon]

So like I said I created 4 indexes to represent all the 4 types of resources on the IngridientsAtHand array

[faint pasture]

are you trying to constrain yourself to this seperate from any other items in the game or is this it for items

[tranquil lagoon]

it's specific items only

resources basically

[faint pasture]

but is there another whole item system?

[tranquil lagoon]

yes

[faint pasture]

is Wood a thing that can be dropped

[tranquil lagoon]

Yes

[faint pasture]

or otherwise treated as a normal item

[rugged sonnet]

How can I make my clamp to smooth in using a curve? Thanks

[faint pasture]

Yeah I'd make 1 encompassing system

[tranquil lagoon]

So basically I have pickup objects and they have all one resource type on the actor that I read in

that part isn't a problem, I can detect them and increment values on the Crafting Table

for me the biggest problem was just finding the correct recipie

[faint pasture]

Yeah that'd be 3 loops nested, you succeed when the last loop has a match on all ingredients

[tranquil lagoon]

Especially since arrays care about indexes right, I can't just compare two arrays if they are in different orders

ah

[faint pasture]

you need to compare the elements

Make functions, stuff like HasEnoughOfThisIngredientOnHand

[tranquil lagoon]

But should I then in every recipe just put in every element in the correct order, and if a recipe doesn't utilize a specific resource I put it at 0?

Or is that not needed

[faint pasture]

no just leave empty

if it just needs wood then jsut add wood

[tranquil lagoon]

Right

[faint pasture]

depends on your metric

Recipe1 takes 2 wood 1 stone
Recipe2 takes 2 wood 2 stone
you have 2 wood 2 stone
what do you make?

[tranquil lagoon]

Recipe 2

[faint pasture]

how do you decide that?

[tranquil lagoon]

It should check for exact match on both material and amount

[faint pasture]

if recipe2 didn't exist, could you still make recipe1 leaving 1 stone?

[tranquil lagoon]

no

[faint pasture]

ok so only exact?

[tranquil lagoon]

I want it to need exact

[faint pasture]

so yeah easiest way might be to have 0 count entries

there's a lot of ways to go aobut it but that'd work

[tranquil lagoon]

And I assume they need to be in the correct order as well

the indexes

[faint pasture]

#blueprint message
You would instead make a function HasExactlyThisMuchIngredientOnHand

order shouldn't matter

all you care about is that you have the exact amount of each ingredient

see how complicated a simple system can get? Welcome to game dev.

[tranquil lagoon]

😭

This is the spear, it requires 1 Stone and 1 Wood

and just to pretend, I have 1 stone and 1 wood at hand

[faint pasture]

You'd loop to the stone requirement, checke that you have exactly 1 stone

then loop to the wood requirement, check if you have exactly 1 wood

[tranquil lagoon]

Huh, but how would I know that the index is the same?

[faint pasture]

bool = true -> for each recipe -> body -> for each ingredient -> body -> do you have exact amount? -> false -> bool = false
-> finished -> failed -> finished -> if bool -> return recipe

you don't care about the index

loop

for each

[tranquil lagoon]

Like this?

Oh wait

[faint pasture]

first make the inner function

input ingredient, output bool

do you have exact amount

HasExactAmountOnHand
Input -> for each ingredient on hand -> body -> if Ingredient = InputIngredient -> return true
-> finished -> return false

that'll return true if it gets 1 match or false if none

that answers the question, do you have that specific ingredient satisfied

do that for all ingredients, if it ever returns false, then the recipe doesn't work

[inner sandal]

Hey guys, sorry to butt in (ignore if need be) , I'm looking for some input on a potential project idea.

I was going to generate an entire train track and surrounding scenery from a spline with a BP, now part of me thinks I should use the terrain tools for this, but do you think it's even a good idea to do all of this in the BP with clever shaders and so forth? It's less about making a whole world and more about generating a "scenic voyage" just from 1 spline, so yes you'll likely see into nothingness at parts but I kind of like the "all consuming power" of being able to do it in one BP.

It's primarily to build up my tech art BP abilities and get used to materials again in Unreal after coming from Unity, but does it just seem like a bad idea and it'd make sense to use the landscape tools instead?

[faint pasture]

It's doable, run time or design time?

I don't think run time terrain modification is a thing but you can certainly add meshes etc

[inner sandal]

design time really, just to make it in editor, fuck about with a spline to make a pleasing path, generate and then build.

[faint pasture]

Sure, should be doable

[torpid hearth]

if someone has the same issue, i solved it by installing a plugin named WMFCodecs

[faint pasture]

splines can deform landscape at design time I'm pretty sure

look at ContentExamples for the roads

[inner sandal]

I'm just curious if it's even a wise idea. I know splines can deform terrain but I'd kind of like to make my spline BP system quite smart, to set points that are bridges or stations etc.

I get a feeling I might build it all and then employers will go "oh that's fuckin' stupid"

[tranquil lagoon]

Is this correct?

[faint pasture]

I'm pretty sure you could just compare struct to struct but that'll work

[tranquil lagoon]

I couldn't find a node for that

[faint pasture]

you can't do an == on a struct?

[tranquil lagoon]

nope

[faint pasture]

ah

i make all mine in C++ and implement that so maybe never noticed it

anyway that should work

[trim matrix]

operator overloading

[faint pasture]

I wonder why it wouldn't jsut default to the obvious if you have properties that are able to be tested for equality

[tranquil lagoon]

Does this look correct?

So this is inside a function called CalculateValidRecipe

https://blueprintue.com/blueprint/3axlyioy/

[lofty rapids]

i would probably get all the indexes if possible

[tranquil lagoon]

Thank you by the way @faint pasture for all the help I am really sorry for bothering with this

[lofty rapids]

if you looped through and saved all the indexes that matched what you have on hand

you would have a list

[lofty rapids]

as a side note you shouldn't cross execution lines like that

it's not a pure node, it needs execution to run

[faint pasture]

If any ingredient fails, fail the recipe

If any recipe succeeds, return it

[tranquil lagoon]

You mean just create a new variable?

[faint pasture]

Sure, it depends on how nesty you're gonna get with it with early returning

If it's all needed functions then you don't need the bool.

[tranquil lagoon]

God I am sorry I really don't understand this at all

I really went over my head here

I don't get what I should do now I don't understand the flowchart you linked

[nimble citrus]

i have this collision box for enabling/disabling input but whenever i overlap with it makes my player go through the mesh for the rest of the gameplay. what's causing this? thank you very much

[weak thicket]

Hi, it happened like this, what I need to do for fix it

[lofty rapids]

is that a bunch of seperate floor pieces but all the same bp ?

[weak thicket]

yes, my gf just send it to me to fix it, she says that she just changed the name of event so thats why it happened

[lofty rapids]

so double click the bp and look inside of it

the compile have a question mark next to it ?

try to compile and look for the error

[weak thicket]

kk thank u for your help

ah solve it, thank u m8

[chilly gazelle]

with AI perception, what leads to an unsuccessful sense? I'm using sight, but none of the characters that should be sensed are being successfully sensed

[lofty rapids]

you need the perception on one, and the simuli on the other

atleast thats how i remember trying

[chilly gazelle]

so they are registering, its just when i get to that bool check so i can set the target, it fails the bool check for succesfully sensed.

[tranquil lagoon]

Okay I just sat down and tried to understand this part by part and it now works perfectly. Thank you so much and once again sorry for being such a bother!

[lofty rapids]

i feel like you have one to many return nodes

not sure you want to return on false there

🤔

[lofty rapids]

what "bool check" ?

[chilly gazelle]

for 'successfully sensed'

man this is so odd. I've checked that the otherBotSensed is valid and the right class, just no dice.

[trim matrix]

the way that you are doing it is wrong

you should probably enable/disable input by using the cast node

and the get player controller (correctly)

why
the 'enable input' is connected with the Player Controller pin
and the disable input node is connected with the Target???

[wise ravine]

@nimble citrus yeah your input's are inconsistent

[nimble citrus]

the tutorial i followed connected them in that way 😅 but i'm not having any trouble with the inputs tho, can this my input shenanigans cause my play to go through the object?

same happened with the other lower box collision (it compares tag's the destroy objects and keep track of them, nothing to do with player controls) whenever player overlapped with that box it also made me go through the object. i changed the collision setting to ignore pawn and it solved for that one. but ignoring pawn on the playerdetector collision doesn't work since it also ignore the input system

[trim matrix]

well, we are just telling you that the nodes are not connected together correctly
You might be lucky that it works right now but will not, later on...

I suggest you to fix it or to actually understand what it does at least... because something is clearly wrong

@nimble citrus

[wise ravine]

What tutorial are you following?

[lunar sleet]

No, input has nothing to do with collision

As for the “well the tutorial guy did it that way”, there’s a lot of bad content creators out there, most tutorials are created by people that don’t actually know wtf they’re doing, just doing it for the views. But something as obvious as plugging in the player controller into the player controller pin when using 2 opposite nodes should be fairly easy to realize, even for someone with little to no understanding of the input system

Also your collision is set to OverlapAllDynamic, it’s not blocking anything, so the things going through each other is the expected result. Doubt it has anything to do with the overlap events themselves, assuming those are even firing

[trim matrix]

true lol

[nimble wasp]

I want to make an array of static meshes. Both the array and the meshes are in the same BP. How do I do that? Would I - on begin play - add each mesh to an array?

I guess, what I'm asking, is there a way to do this in one node or do I need to do this.

[chilly gazelle]

I have a BP grenade that is set to block all, and my terrain is set to block all, but my grenade is going straight through the terrain. How do i fix this?

Grenade is set to worlddynamic, terrain is worldstatic.

[sage lagoon]

I've barely started making a blank map with a floor and I've moved the camera so it faces the player from a side. So now, the player character goes up and down when I try to push left and right; and he goes right or left when I push down or up. I know it's the camera, but I still need to set the input buttons accordingly. Besides setting input keys in Project Settings (which I tried, by the way), what would be an effective way to set the controls according to the camera's position? I'm not sure if using Set World Rotation to modify Game Controller would work in this case.

[main lake]

In your BP, where you array variable is click on the little eye next to it to make it instance editable. Compile, click on your variable on the left panel and now on the right you can see that you can press a "+" button to add items to that array, add 4 elements and drag and drop your Sphere, Cube, Cone and Plane 1 by 1 to each of the 4 elements of your array.

[main lake]

In your character BP, play with 1 of these 3 poroperties that should do the trick

[sage lagoon]

Oh, I see. So that would let the player move up and down the planes, too.

This will be for a beat-em-up action RPG, so let's see...I could imagine the character moving like this during fights but not while exploring. So I wonder if I could have the character face north or south when going up and down when not fighting.

[main lake]

You can modify those through code at runtime to switch them the way you want them 🙂

[sage lagoon]

Hm, okay. I guess I can look at those and play around with them, then make a variable in the game instance that controls whether or not the character can face north or south.

[sage lagoon]

Though the player still moves left and right when Up and Down are pressed; and up and down when Left and Right are pressed.

[main lake]

Mhhh 🤔

[main lake]

Which setting did you modify in the ones I showed you above ?

[sage lagoon]

I only checked the Yaw, but it only makes the character stay facing left/right when moving up or down. I tried to modify the input on Project Settings but it doesn't seem to work, either.

[main lake]

Try the "Pitch" rather

[sage lagoon]

Same as before. I know it has to do with the camera position, but I'm not sure if setting the camera rotation for the controller will work.

[main lake]

Then i don't know sorry 😬

[sage lagoon]

Here's how it looks.

[main lake]

did you check youtube tutorials ?

[sage lagoon]

Hm. Well, I can put the camera in front of and on ground level instead.

Okay, got it.

I just moved the camera to a better position.

[sage lagoon]

Speaking of tutorials, would you happen to know of any relating to beat-em-ups?

[main lake]

Nope, sorry 🤷‍♂️

[sage lagoon]

You're good.

Still, thanks for your help.

[undone bluff]

are you working from the third person template?

[sage lagoon]

Yes, and I figured out how to get the movement controls to work properly.

I just moved the camera behind the player and above the ground.

And some distance away, too.

[undone bluff]

yea I can explain what the issue was

so the movement setup there should be using the right vector of the control rotation to determine the axis along which to move left/right, similar for for- and backwards

the control rotation is something that is changed by the Add controller Yaw/Pitch Input nodes

the camera then by default follow the control rotation

I assume you simply disconnected IA_Look?

then moved the camera to the left of the character but the control rotation still starts towards the front

The best and most versatile solution here would be to get the rotation of the camera instead of control rotation

when you get your vector to add movement input towards

then all your movement would be relative to the camera

[deep void]

Can anyone explain how I can wrap my head around this error?
Its in a BP pawn, that has a camera on it, I simply want to take a screen shot from that camera, but am getting this error and cant find a solution online.

[undone bluff]

did you drag a camera from the add object menu onto the level?

so cameras in unreal are components, and the node you have needs a component reference

when you place a camera in a level it needs to be wrapped in an actor

because components can only exist attached to an actor

you essentially have a reference to that wrapper actor

and you need to get the actual camera component inside

you should be able to just drag off and get it

[deep void]

no I added the camera in the components section of the pawn BP.

[undone bluff]

ohhh

seems like I had it the wrong way around

[deep void]

so i dont have an actor, I was hoping to use the camera on the pawn

[undone bluff]

the node wants the wrapper

and you have a component

[deep void]

I've tried get owner on my camera, but still get an error, cause it wants actor.
Was hoping there was a way around it without having to make another camera and actor

[undone bluff]

yea the owner of the camera is the pawn and not a camera actor

you will probably have to spawn a camera actor for the screenshot then

[deep void]

fair enough, thanks heaps for chatting it out 🤝

[undone bluff]

np, probably look around to make sure this is the proper approach to take a screenshot for your usecase, I can't help much on this topic

[deep void]

that's all good, appreciate the reply.
I'm hoping there is another way, so I'll keep searching,
The pawn has a camera that the user can possess and look around, so i want the screen shot to be exactly what the user sees when possessing the pawn, that's why I wanted the screenshot to happen from this camera in the pawn.

[undone bluff]

my first thoughts are to either use the HighResShot console command or a scenecapture 2D if you intend to do anything with that image in game

(Execute Console Command node works in shipping build)

[dark harness]

anyone have a problem with Level BP Diff not showing anything in 5.3?

[primal hare]

Hi, The jump animation gets stuck for a second before landing

it was working fine before updating the animations

the animations themself aren't that long

the jump loop just seem to get stuck longer than it needs to

[gentle urchin]

Is it a transition issue ?

[primal hare]

seems like

[gentle urchin]

Should be able to verify by viewing the animBP

Looking at the statemachine

[primal hare]

I'm just following tutorials

[gentle urchin]

Be a scholar, not a follower ^^

[primal hare]

but tried making trantiions longer shorter, didn't work

steps and time 😉

[gentle urchin]

But is it stuck in transition?

Does it stay in JumpDown while this bug happens

Or JumpIdle perhaps

[primal hare]

please see the video

[gentle urchin]

In the anim graph...

Vid doesnt show that

If thats the case then your transition rule might be wrong

[primal hare]

how do you see that while the game is on?

[gentle urchin]

Just open it in a new window

[primal hare]

I have both pie and bp > locomotion windows open, but there is no indication in the bp window while playing

[gentle urchin]

You may need to select the object instance in the top menu while it plays

[sick sky]

Hello! Is there a BP node for "Happen only in development build?" or something like this?

I want to add some more debug information for certain areas of my game, but ideally this should only be done inside of a development build and not in a shipping build. So I would like something like a bool that I can use and say, if in dev build do X, but if shipping ignore.

[gentle urchin]

You do any cpp ?

@silent drift

you can use this in bp

/** Unknown build configuration. */
Unknown,

/** Debug build. */
Debug,

/** DebugGame build. */
DebugGame,

/** Development build. */
Development,

/** Shipping build. */
Shipping,

/** Test build. */
Test

these are the options

[spark steppe]

there's a whole option to toggle nodes to development only mode

somewhere in the editor settings is a keybind

https://youtu.be/mP8HJkccCzw?si=KN5h20vnlKS5k-67&t=132

[gentle urchin]

Ohhh right there's that doo

[silent drift]

Oh, need to look into both, and I'm starting to move over to CPP, but I don't feel too comformtable with it yet. Thanks @gentle urchin and @spark steppe

[gentle urchin]

so you can even mark specific instances of the function as developent it seems

or disabled... im amazed

weird that this isnt a right click option

Feels like a drag creating a new editor module for this

https://forums.unrealengine.com/t/how-do-i-make-a-plugin-to-add-to-the-node-actions-list/355084/2

[primal hare]

thanks for your help. The issue was the animation itself it seems, rexporting and reimporting solved it

[silent drift]

Thanks again! That is great! And I need to move over more and more to CPP (because I also want to get back into learning it, I used it like 7 years ago, but then stopped since I started working for a company doing only level design without any coding what so ever), so I think it will take me a bit to get into again.

[silent drift]

ANother thing I'm wondering with BP (this might be a CPP only thing, so maybe I just need to start with this sooner rather than later, I'm just scared of getting to slow on my project), can I add console commands through BP? For example, I want to add "TurnOnGodMode", and if I write this, it will turn on god mode on the player, rather than having to add a new debug widget or Key (since I will soon run out of good debug keys).

[gentle urchin]

Not directly,

you'd need to make your own fake console I think ?

nvm

[silent drift]

Yeah, that is what i suspected as when I googled it, all answers talked about Cpp. 😄

[silent drift]

But that says process console commands?

Doesn't look like I can create a new command? Or maybe I'm missunderstanding something.

[gentle urchin]

Its a pretty odd example

as LevelBP is the one place i wouldnt want to have this XD so how would we target any class

[silent drift]

Yeah, looks like I really just need to bite the bullet and start with Cpp... I'm just scared of breaking the game as soon as I start with it again. 😄

I mean I will break the game, I just hope I can fix it.

[gentle urchin]

break it ?

nah It'll be fine 😄

https://tenor.com/view/trust-the-process-emi-rahul-hinduja-global-esports-prakriya-par-vishwas-karen-gif-4853425731637184423

[silent drift]

Haha

Sorry for asking, but do you know if there are any good C++ good example projects for me to look into the basic setup? Just as a starting to point to see how a character is setup and all again. 😄 @gentle urchin

[gentle urchin]

There's quite a few, with their own quirks and crude corners

ActionRPG, ShooterSample, CropoutSample,

If you're diving into GAS , GASDocumentation from Tranek is a starting point, Naxrim, Lyra (perhaps overly abstract)

[silent drift]

Thank you! I'll start grabbing ShooterSample and ActionRPG!

[sick sky]

it could be a good thing to have a "go to" in function to avoid big white lines

[thin panther]

Also quite messy. For the same reason you don't use it in C++

It breaks the flow. You can no longer glance to understand things

If you want clean code, that ain't bp

[sick sky]

true

you got a point

[gentle urchin]

I disagree with the clean code aint bp part*

Visual scripting can attain clean code aswell

In fact id argue it often can be far easier to have a good overview in visual scripting compared to pure text ones

A goto: is always horrible to read imo

[neon acorn]

Nope, I will be trying to utilise this https://www.youtube.com/watch?v=A9dp3cmCFtQ and see if I can get things working but right now, my VS version causes issues with UE 5.3 so I am paused until 5.4 launches in GA to try it out. I will make a blog post once I get things working in my RTS so maybe look forward to that?

[languid wolf]

Thanks for the reply, good luck with your RTS

[weak iris]

Hi, i've been following matt aspland door and key system tutorial here https://www.youtube.com/watch?v=Bcle9sSS4Oo&t=69s
It works fine but only if i have the key already lying somewhere on the level in order to match it with the door i want to open..
How would i go on doing this if i want to spawn the key instead of it already lying on the level?

^i need to be able to pick the door from the blueprint instead of from the level/outliner.. anyone have any suggestion?

[thin panther]

You can't. How would it know what to pick.

In that menu 0 to infinity of that blueprint exist, and so do 0 to infinity of your door, because it's not in a level.

Well actually 0 of either exist, because you're not in a game world

[weak iris]

i spawn the key from a barrel

[thin panther]

You'll need a different way of picking it

[dark drum]

Are you wanting it to automatically unlock the door when the key is picked up?

[weak iris]

well not really auto.. i still need to go to the locked door with the picked up key that spawned

[dark drum]

Ok. Well if the key needs a reference to the door, this actor manager might be of use to you. You can add the actor register component shown in the video to the door, give it a name and then on the key, use the get registered actor function, specify the same name of the door. On the key, you could add a variable name thats used for getting the door and expose on spawn. That way, when ever you spawn a key you can specify the name of the door it should unlock.

If needed, you can cast the fetched register actor to the specific class you believe it should be.

https://youtu.be/RygVokx-mzk

[weak iris]

okay thanks i will check it out

[gentle urchin]

Pretty handy! Slap the valid check in the bpfl aswell, and return a bool to ease it 😄

Guess it ends up the same. Didnt know you did YT content

[dark drum]

I tend to be selective with the tutorials I make but yea lol.

[gentle urchin]

Ultimate Dialogue, now that begs me to click it 😆

[dark drum]

Well it's received some high praise. 😛 It's not perfect but for most people it's better than most free systems you can find on YT. lol. (I have a personal V2 that uses modules 🙃 )

[spice viper]

For actor mobility, Stationary vs Movable. I get to change location you need movable, but can you change rotation on stationary?

[dark drum]

I don't believe so. Stationary means it doesn't move which includes rotation. You can hide an unhide but that's it.

[gentle urchin]

The youtube library of tutorials surely is not just gold, thats for certain :p

Personally Im using an open source plugin which feels quite nice to use, and gives pretty clear flow. The dialogue can there be implemented eithernin the NPC actor itself, or in an external actor if it's a conversation between multiple npc's and player

[dark drum]

I've seen a few nice dialogue plugins that utilize the behavior tree graph but I wanted a BP only solution that didn't require me to be staring at a datatable.

[gentle urchin]

I never liked those BT ones 😆

Feels like forcing something to be something it is not

DT is also suboptimal, As you say, both staring at, and tracking the convo is pretty hard

I prefer straight up Nodes with easy to see branching, rewards, decisions, etc

[dark drum]

Definitely. My system is all done in BP so you get the left to right flow which is nice. This is an example.

[gentle urchin]

The passthrough felt a bit weird to me 😆

But yeah getting them in a graph is neat

[dark drum]

Yea, I didn't like having to add it but it was the only way I could get it to work where it had to pretty much traverse the graph again. Otherwise, you'd have to give each piece of dialogue an ID of sorts which I really didn't want to have to do haha.

Having said that though, it gives you a way to trigger something when that piece of dialogue is displayed which is nice.

[gentle urchin]

Or latent nodes with callbacks ^^

The one im using also support:

• color coding of the nodes
• bp events anywhere
• custom runtime conditioning
• inline text formatting
• custom icons om the nodes

Makes it very versatile. Working on an export function so we can.. export it 😄 and possibly import it

[sick sky]

i guess its some private plugin ?

[gentle urchin]

Not really no, well , my edits are , for now atleast

[sick sky]

so you are using a marketplace plugin ?

[gentle urchin]

It didnt meet the marketplace criteria , so it never got there

Its called Dialogue Nodes

Open source

Wish they made a git repo for it

[sick sky]

me sad

[gentle urchin]

Using it on 5.3

No big issues

[dark drum]

Yea it looks pretty cool. I guess that's the advantage of using C++ as you have access to more stuff. I would have loved to have been able to have custom nodes in the BP only system.

[gentle urchin]

Yeah for sure. Took a while to get used to slate tho 😅

Adding the asset view at the bottom of the nodes was painfull coming at it with 0 experience

[sick sky]

is it very hard to add UI to the editor ?
i tried some stuff with editor utility widget, but it was "limited"

for example, i wanted to automate a part of this process

but, this means editing DTs and enums "at runtime"

[gentle urchin]

Cant edit enums at runtime afaik

DTs can be

[sick sky]

because for DTs, there is Fill Data Table From CSV String

[frosty heron]

make little sense too to me

[gentle urchin]

If tou truly desire it

You can simply "AddRow"

[sick sky]

isnt there a UE warper or whatever to edit in in editor ?

[gentle urchin]

Editor != runtime

Also why would job location be an enum

[sick sky]

thats why i wrote "runtime"

because, the editor is running, but not the game

[gentle urchin]

😆

Thats called editortime

[sick sky]

yeah mb

[sick sky]

simple : you can have a dropdown

[gentle urchin]

Gameplaytag

[sick sky]

i dont have to type the whole ID

[gentle urchin]

Is the winnner

[sick sky]

well there is no hierarchie so kinda no points now

[gentle urchin]

Sounds like it

Job.task

[sick sky]

yeah but there is to much to edit

for not much better

[gentle urchin]

Thats another story

[sick sky]

also, even if keys of DT can be gameplay tags, i still needs a custom structure

[gentle urchin]

But your current flow is very slow

[sick sky]

for settings up a job ?

or you mean the code running at runtime

[gentle urchin]

Setting up a job

Like 6 steps

[sick sky]

well its a complexe system with a lot of modularity so i had to make it this way

[sick sky]

(it takes 5m)

[gentle urchin]

Enums are not very modular/flexible

[sick sky]

the modular part isnt the use of enums

i just used enum for easier selected in details panel

[dark drum]

I would just use gameplay tags. They're pretty handy. You can copy the gameplay tag as name to use as a key in the datat table.

[sick sky]

yeah so kinda the same rn with enums

if i had to redo it i'll use gameplay tags

btw, is there a limit to gamplay tags count ?

[dark drum]

Not that im aware of. You can even have multiple ini files for the gameplay tags to help keep them organized.

[gentle urchin]

More than enum atleast

[dark drum]

I didn't realise there was a limit but I guess it would be what ever the max number you get get for an Int. Although it starts to get slow when you add about 30-40 entries to a single enum.

[sick sky]

and how much is enum

[gentle urchin]

Uint8*

255

[sick sky]

im fine

[gentle urchin]

for now

[sick sky]

the day i have 255 jobs i finished the game xD

[gentle urchin]

Im curious what that setup is for tho

Why store locations in dt?

[dark drum]

You'd be surprised. Jobs could easily turn into tasks. lol.

[sick sky]

im playing rn, when i finished i can share the workflow behind the jobs

[gentle urchin]

Got time for games? Lucky you!

[sick sky]

im in "vacation" rn

[gentle urchin]

Me too

[sick sky]

so i can play 2-4hours a day and work 4-8hrs and go gym

happy week

[gentle urchin]

Got no time for games either way

[dark drum]

Does anyone know if there's a way to move custom events and timelines to a new event graph without copying/pasting?

[remote meteor]

collapse into graph maybe, cut and paste is the only way though if you really want to move it

[sick sky]

the workflow is :

• i have a job
• for this job, there can be multiple locations
• for each location, there is multiple task to do the job

this is super practical for me because when assigning job, i am doing

• assign random job to player depending team
• for this job, assign a location
• let player complete or not the job
  (this way, i can control if a job location can have 1 player only or more)

then, each ABP that is from the parent job can have whatever adding values to the goal and try to validate the job

DT_PrisonerJobs - DT_JobLocations

[dark drum]

That's what I thought and ended up doing. Thankfully I only had to reconnect a couple of nodes.

[sick sky]

is the job location volume to have so extra stuff like a "location ping" widget, and control who can access the zone

[gentle urchin]

Wouldnt you want it to find the suitable locations dynamically ?

So each cell would have some identifier for... well .. Cell...,

and the Prison.Cleaning task would look for Cell locations?

through the JobTask manager 😄

"get all Cells" -> While (!bDirtyFound) -> Get Cell(index) -> IsDirty? -> bDirtyFound = true -> Assign myself to the cell

If you need several layers you can scope them to specific buildings and even specific floors if you wanted to

Or 'wings'

[sick sky]

to much work at runtime for no reasons

also, there is a lot of different types of job
so your idea would probably only work for generic stuff like the cells cleaning

[gentle urchin]

But not for ?

[sick sky]

cant explain

the jobs are not yet implemented

[gentle urchin]

Patrol routes?

[sick sky]

any job

[gentle urchin]

Just slap thenroute in a bpActor that registers to the same manager. -> PrisonB.WingC.Cafeteria

Destination actor contains the spline to patrol along

Sorta like smart objects do

Smart objects control the logic at the interactionpoint iirc

[sick sky]

my beaytiful function to assign roles to all players (can wait to add AI inside )

[gentle urchin]

Ohhh right

I remember your game now

[frosty heron]

That's a lot of nodes, how are the roles assigned to players?

[sick sky]

i never talked about it if i remember

[gentle urchin]

The longest journey ™️

[sick sky]

appart from being a "prison game"

[sick sky]

you want screens ?

[frosty heron]

nah maybe a brief description how roles are assigned

like if it's done randomly

[sick sky]

basically, it get players, then filter between guards and prisoners

• then get a random job
• get a random location (if any)
• if the job is taged as "one player per location", remove this job location so no players can have it
• call event in player state to set some values such as displaynames and task goal

most magic happens there

[frosty heron]

this should all be done on server right?

client doesnt need to do any logic, assigning roles is server job

client simply receive it's assigned role

[sick sky]

its in game state, runs on server

[frosty heron]

or go to extra mile and only have the variable set in server

[frosty heron]

ahh ok, just saw a server RPC inside it so was wondering if it run on client too

[sick sky]

doing this screen shot made be realised i got a var that is used once, so ima remove it

the saving int of random

btw, when i do enum > name i always get issue

so i have to convert to string before

i think i adds a prefix like Enum before

[dark drum]

I've just checking I've not missed something in an update but I assume we still can't have delegates variables. (I know you get get them as inputs on a function/event)

[dark drum]

Enum as name is 'Enumeration_0', 'Enumeration_1' etc... Something like that. Enum to string gets the friendly version lol

[sick sky]

oh okay

thats why

[gentle urchin]

there were some bugs with the conversion tho wasnt there

or atleast, there could be

[gentle urchin]

not related but from our earlier convo

the pic i sent didnt exactly cover anything xD

And no, still no delegate variables :'/

[frosty heron]

how to conjure those colorful nodes?

looking neat

[gentle urchin]

#slate is your friend

[frosty heron]

Tried befriending it

I couldn't understand it

[gentle urchin]

Exposed most of it to the plugin settings

[frosty heron]

maybe one day 😛

[sick sky]

same here

would love to dev custom stuff, but, im scared of slate

[frosty heron]

just want a quick button I can click on editor to change map

like in Lyra

[gentle urchin]

that's the one you'd override

[frosty heron]

Editor module I suppose?

[gentle urchin]

yh

[tight pollen]

The fewer variables replicated, the better, right? so if something doesn't happen often it's better to use RPC instead of replicated variables.. Yes?

replicated variables are updated all the time? or only when there is a change?

someone can help?

[dark drum]

A replicated variable would only get sent across the network when it's changed so when comparing to RPC it wouldn't make much of a difference. But in terms of you're initial question, the less you replicate (that includes RPC) the better. There's only a finite amount of bandwidth so learning how to do more with less can be good.

[gentle urchin]

Altho bandwidth is pretty skyhigh these days ...

it can also become a big server strain

[tight pollen]

I have 100 skills, it's probably better to keep these 100 skills in a Map variable on the server than to replicate each one

[frosty heron]

@tight pollen replicated variables are updated on the next NetUpdate()

or something like that

how often depends on the frequency set

server RPC to update non replicated variable is not always the answer, it can work if you know what you are doing but you will need some extra steps to make sure that clients are sync all the time

[tight pollen]

and if necessary, the player will send a request to a specific skill

[sick sky]

?

[frosty heron]

100 skills, 5k widgets, thousands of actors :P, cmon man try to love your self

[tight pollen]

but if the only way to check a given skill is to send an RPC, there should probably be no problem with synchronization

unless you have something else in mind

[frosty heron]

there will be problem

Server RPC = run things on server

but since you don't want the variable to be replicated

u gotta update the client value manually

[tight pollen]

hmm

so, what will be best

[frosty heron]

I'm doing mp rpg too

but I don't know how far I can push it

gonna start as smalllll as possible

i seen people having trouble sending data over the network and they werent even sending much

the dude ends up breaking up the data

and send it overtime instead the whole bundle in one go

well best to ask #multiplayer experts

[gentle urchin]

No need to replicate the skill itself , only the avaliability of them

Anyhow 😄

[tight pollen]

but also the level of a given skill

[gentle urchin]

Thats the avaliability

Level 0 =unavaliable

[tight pollen]

ok, but do everything on the server or replicate the Array variable

[frosty heron]

I rest my hand in Gas

[tight pollen]

but, will it be something bad if I manage a Map variable only on the server and, if necessary, if the client wants to access a given skill, just send a Server RPC?

of course, at the beginning of the game it will get all skill data from the server

[gentle urchin]

Sounds like a troublesome setup

[frosty heron]

I will just use #gameplay-ability-system

[tight pollen]

only blueprints?

[frosty heron]

need little bit of CPP for the boiler plate

rest can be done in blueprints

[tight pollen]

I'd prefer do it without it

without GAS

[gentle urchin]

Preference goes out the window with your scope, sorry

[tight pollen]

ok, but if you were to do it only with BP, without any GAS, etc., how would you do it?

[frosty heron]

I wouldn't do MP RPG purely using blueprint. Wouldn't mind tackling chess game or horror game where I just collect items and do puzzles with bp only

don't take my words for it, the mod in #multiplayer and those that wrote MP compedium specifically call out blueprint multiplayer to be limited

[thin panther]

you won't be able to really make an rpg singleplayer or multiplayer in only bp

Multiplayer requires C++

[frosty heron]

oof my old game is single player rpg, using only bp

ngl the combat is trash

[tight pollen]

or I will just make everything saved locally and it will be prone to cheating

[frosty heron]

That's not even the issue

[tight pollen]

🙂

[frosty heron]

I wouldn't even worry about cheating at all in my game

just gonna do basic check on server and rewind

but not gonna put effort in defending the game from cheaters at my current level

[nimble wasp]

What is the best way to do this?
array of 4 entries
turn 1, get and print 4 entries at random
turn 2, get and print 5 entries at random
turn 3, 6 entries
turn 4, 7 entries
end

[frosty heron]

not like you can in blueprint anyway

[lofty rapids]

depending on the turns, i would just increment an integer that says how many to pull from the array

which i'm hoping is an array ?

[tight pollen]

BPs are not that bad, if I limit Ticks and call everything when it's actually needed, nothing happens..

[thin panther]

on turn, have a for loop, where the number of iterations is turn number + 3.
in the for loop generate a random number between 0 and last valid index, print output of that array's contents at that index

[thin panther]

It's not even performance that kills you.
It's lack of features.

Though performance will kill you when you get close to having a finished game

[frosty heron]

That's not the core issue for multiplayer

[frosty heron]

100%

think about it, you can't even make a smooth sprinting system with bp only for multiplayer

that's how fast you hit the wall

[tight pollen]

I know

https://www.unrealengine.com/marketplace/en-US/product/general-movement-component

[frosty heron]

you gotta do what you gotta do, if the goal is to make multiplayer game, start to learn cpp today >_>

[tight pollen]

can also use this

[frosty heron]

it's 350 dollars if my memory serve well

and it;s not really a silver bullet

though come with extra features

like having what CMC don't. Eg different shape for collision component

once you need to implement your own feature, u will hit the wall again

so best to get out of Unreal Trial version (bp only)

ooof 1k aud

[gentle urchin]

Released?

[tight pollen]

I won't buy it 😄

[frosty heron]

sort of, to secret society.
I'm still working on it

[tight pollen]

I'm waiting for this system from Epic

they're supposedly doing something

[frosty heron]

Mover 2.0 is out but I don't know how much you can do with bp only even if they pump new feature

[thin panther]

mover 2.0 is going to be very c++ heavy it seems

[gentle urchin]

How does one ||secretly apply||

[frosty heron]

failed game anyway

working on multiplayer project too for the mullah now. I made the graphic a lot better (I think)

[gentle urchin]

You walked into the MP trap aswell huh

[frosty heron]

blueprint only users are not their main target audience

the faster you accept it, the faster you will resolve your issue

[tight pollen]

but if I want a skill tree that contains 100-1000 skills, and I will do it in BP, is there anything wrong with it 😄

?

[frosty heron]

had to explained to my team that multiplayer is HARDDDDD

[tight pollen]

I will learn C++, but I don't have time at the moment

[frosty heron]

but they are like, It's easy man CMONN

[gentle urchin]

You'll likely sacrifice user experience just yo have it running

[frosty heron]

when im the only one that codes

made me leave unreal for months just to study programming basic

[gentle urchin]

Its easy to talk about lol

Hard to actually do

Same as my team 😆

"Lets just do this. Thats easy, right? Just A + B = C!"

[frosty heron]

They think it's the same as making warcraft 3 map

where all the networking stuff is served on silver plate

[tight pollen]

ok, I'll do everything locally, and the server will simply check the values

I simply need a solution only in BP, I am not interested in C++ at the moment

[gentle urchin]

Scope down

Heavily

5 skills , few players, see how it goes

[thin panther]

With what you want there is no "simply"
You're going above the scope that even most AAA projects do. Simple is not a word that exists with those requirements 😅

[tight pollen]

come on, I'll think of something and do it 😅

[sick sky]

its funny how everyone's first game is 95% of the time a rpg

[frosty heron]

I can't remember my first game, made countless "games" before I commit to my project

[gentle urchin]

Didnt we all

[frosty heron]

just want to complete a title, I stop worrying about making it perfect

[gentle urchin]

I got 40+ projects laying around

[frosty heron]

yup, don't we all 🤣

[gentle urchin]

Maybe 5 were serious attempts

Non released

[worthy flume]

Hello, I need help, tell me what is the name of this blueprint, please

[gentle urchin]

Not even close

[gentle urchin]

Multiply vector / float

[sick sky]

i dont want to break your dreams of making a AAA game, just dont overlook what experienced people say here

[thin panther]

based on the colour, looks like a single precision float too

[sick sky]

look at me, making a MP game in BP only (for now)

[sick sky]

i hate doing small projects, i prefer having a big scopes so i can test everything and learn from it

[thin panther]

I'd like to reiterate that C++ required doesn't mean all C++, you only use it where needed.
You can still be pretty heavy bp

[gentle urchin]

89/11 split works fine ^

[sick sky]

most of it are just containers of marketplace assets

[worthy flume]

Yes, the one on the right, thank you

[thin panther]

Watch out PrisonGame. You're not ready for PrisonGame

[sick sky]

im lazy (and dont want to pay money) so im using a usb stick to do stuff when not at home

i would love to have perforce on network

[thin panther]

Good news, source control is free

[sick sky]

i got it locally

[thin panther]

Git with Azure DevOps

unlimited and free

[sick sky]

im using bp a lot

[thin panther]

doesn't matter

Perforce only makes bp's better in huge teams

[gentle urchin]

Azure is life

As long as its free

[sick sky]

i checked git for BPs and support was kinda bad

[thin panther]

you don't need support other than push and pull

you're working on this by yourself, file locking is not a thing you need

[sick sky]

it was more about diffs

[thin panther]

the engine can diff bp's

[sick sky]

i guess i can give a try to git

[thin panther]

perforce can't diff binaries either

helix merge does not support that, it has no concept of a uasset

all the diffing is built into the engine

[sick sky]

oh

i was lied this whole time !

[sick sky]

so Azure DevOps has a infinite time free plan ?

[thin panther]

Yep, just don't use it's build pipeline, it's shit

Technically it's not "infinite" but it's a 250GB soft cap on the repo, and unlimited LFS space.

So it's more than enough

[sick sky]

do you push all Content in the "repo" ?

[sick sky]

thats fine

well ty for sharing

[thin panther]

You can choose what to do, I would personally and avoid LFS, but if you want you can setup LFS for your uassets

just the unreal .gitignore, an azure repo, set it up as your remote and away you go

[sick sky]

idk what LFS is

[crystal flax]

Hey guys I am facing one issue I made one character creation system in which we can customize our character from main menu and it will load in the map but the problem is that it is passing from the function but not loading what should I do . I know it is quite complicated as it is done by me but if anybody could give me any guidence really appreciated

[thin panther]

Large File System. Basically hosts your large files elsewhere, and in the actual repo, your file is replaced with a text file telling Git where to retrieve the real thing from.

so your main repo isn't super bloated

[sick sky]

so you use this

[lofty rapids]

wdym "passing from the function" ?

[crystal flax]

i ran the bollean print string which gives result says that true which means game is loading

[rugged sonnet]

How come my sphere always starts in the same location? Can somone help me please?

[crystal flax]

load function is working i mean to say that

[meager yoke]

Hello!
So i started learning UE5 3 days ago and I've been working on a personal project of mine.

I am trying to make a Random Number Generator Loop that gives random Float Values after every 5 seconds.
I've tried searching on YT and Forums but I haven't found anything yet 🥹 ... Asked ChatGPT but i didn't understand the instructions it gave.

[lofty rapids]

so you load the other level, and that has a load on begin play or something ?

or you use your character ?

[crystal flax]

i made one component where all the save and load function are store then in my both controller like the main menu controller and game level controller i called those function respectively with the help of component

[thin panther]

look into matheww's channel on how to use set timer by event.
then once you know how to use that, have your event pick a random float value in your given range.

[lofty rapids]

so the component is on your character ?

[meager yoke]

Thanks I'll look into that 🙇🏻‍♂️

[lofty rapids]

when you load a level all that stuff "resets"

it doesn't persist i believe

[crystal flax]

yeah it is in my both character

[crystal flax]

seem like this only so is there any way i can fix it or i need to start over

[lofty rapids]

you need to store the information in the game instance or something that persists

idk what persists except game instance

then use that data when you load the level

[crystal flax]

ohh i was using save game for that i am storing that in my save game and loading with the help of that like the character name is loading but meshes are not

[lofty rapids]

ok so your saving all the info, and on begin play of the character your loading it ?

[crystal flax]

i am saving the infor when my player click on start button in main menu and loading on the begin play of another level

[lofty rapids]

makes sense

and something is wrong with the data ? did you check to make sure your getting the proper data ?

[crystal flax]

i ran a print sting for that but i my main level i am getting the meshes which are defaul not the one which i have set

that is the problem

i think i digged my own grave i have to submit this tommoro morning and my main thing is not done is there any tutorial from where i can start and achive desire result in one night

like i have to make this from start i made earlier but on that we change mesh using arrow and integere and unit that works preety easily

but in this i need to specificly change mesh using images and buttons i can do this using multiple widget but i decided to go with one widget only

and there i messed up

[lofty rapids]

so the problem is the main menu isn't working as expected ?

the loading is working ?

[sick sky]

sorry to come back to you, where did you find the specs of free repos ?
the only fthing i found is this
i didnt find anything either of the project page

[crystal flax]

main menu is working absolutly fine everything 100% just data is not loading and i think i messed up some where bcz and now i am not gettign where did i meesed it up

[lofty rapids]

well i'm assuming in the save or load

since thats the problem

but maybe something with what you are saving is incorrect

[crystal flax]

yeah i am thinking that too but i ran print string they are also working fine

[lofty rapids]

so the data is fine thats a plus

[thin panther]

ooh god now you're asking lol.

That unlimited is the thing you should focus on.
I believe the 250GB soft cap was deep in a support article, and I believe the unlimited lfs was mentioned in a visual studio developer blog

[crystal flax]

yeah

[lofty rapids]

so is it just how your loading the data ?

because if the main menu works fine, its saving and loading correctly

the really only thing would be how you load it

[sick sky]

"unlimited repos", sad that we have no info on storage

[crystal flax]

i am using data tables and structs and for loading data i told you that i made one blueprint component in which i have my save and load function and in my main level pplayer controller on event begin play i am calling that function

[thin panther]

We do, like I said, it's just scattered

From official sources

I just don't have links on me because it was like 8 months ago
