blueprint

[rough warren]

it is creating an object in the scene though

oh yeah

i gotchu

[zealous fog]

N, its creating it in that instance

That gameinstance

[rough warren]

is there a way though to put that spawned object into a folder though

[zealous fog]

But gameinstances are destroyed when you quit the game

What are you trying to do

[rough warren]

true, but for organization when debugging

[zealous fog]

Or why do you want that

Not with blueprints

Anythings possible in C++

[rough warren]

alright

[zealous fog]

Dont know how much work it would be though

[rough warren]

can you convert blueprints to c++ ?

[zealous fog]

Dont know much about it

Yes

But you can't write this in blueprints

But for performance you can nativize blueprints

Will be deprecated in UE5 though

I cry cause it made my game go from 40 fps to 100 fps

[rough warren]

i mean UE5 is really optimized though

I'm spawning 250k buildings with like 1k+ verts in each and still getting good fps

obviously I'm gonna optimize it, but even unoptimized it runs really well

[zealous fog]

For graphics yes but the performance you gain from nativization isnt graphics

So I have a lot of projectile moving on tick

By nativizing that it gained a lot of performance

But yeah doesn't help a lot of games

Depends on what you are doing in your blueprints haha

[crystal crown]

Hello! i'm newbie

I have made a pawn plane with pitch, yaw, roll & acceleration, deceleration.

How can i make it so roll will return to world plane (level itself out) let's say if the angle is not more than 90 degrees.

Also i would like to connect roll and yaw but have so far failed.
I don't want to make this post too long, feel free to message me.

[glass magnet]

hm ok so hey yall

[undone wyvern]

Hey there, would anyone kindly be able to explain to me what i'm doing wrong? (Artist here, and a total beginner at BP.) What I'm trying to do is make my lights turn on when I press E inside of the collision box, and when I press E again they turn off, but with a slight delay or fade out (timeline)...

[glass magnet]

so last night i was here trying to figure out how to get an outline and i did get it! on a box, im trying to input this for a player character as well. Any suggestions?

this is what i had last night for the box inking

it basically has a black outline but when you hover over or click it will be red

[odd ember]

no? where would that be?

[glass magnet]

works well but doesnt work when i tried to translate it to my player character

[crystal crown]

search youtube for light switch.

[undone wyvern]

i did, haha thats what got me into this whole mess...

[zealous fog]

I'm just gonna send you this classic video about blueprint communication

[undone wyvern]

thank you! truly do appreciate any pointers... coming from blender here and wanna get my head straight into bp asap

[zealous fog]

Because I could look through this code and tell you what I think you did wrong (I did look I believe this is the light blueprint so you are using the event input e, but you are the player not the light, so it won't do anything) but the fact is that this is not a conventional setup so it's better to learn how to do it correctly immediately

And how to interact with objects in your world correctly

https://youtu.be/EM_HYqQdToE

It's a classic vid around here haha

[hollow vessel]

Guys I was wondering if c++ is better then blueprint. I have been making games using c# with unity for a year now and I want to learn c++ and I though unreal engine is the best way to learn it. Coding seems easier then blueprints in my opinion. I was wondering which one is better?

[zealous fog]

Neither is better, they can't both be used to make games very well, the recommended way to go about it is using both

That's what epic recommends

And also does in their own games like fortnite

They also have sample projects that use both so you can see how they do it

[undone wyvern]

@zealous fog Thank you mate

[hollow vessel]

How can you use both? It makes you choose one when starting a project

[zealous fog]

Epics got a bunch of documentation and samples on that

[zealous fog]

Oh

That doesn't matter

You can still add the other

[brazen merlin]

Choose bp then make a cpp asset

[crystal crown]

@zealous fog Maybe you can help? See above

[hollow vessel]

whats cpp asset

[brazen merlin]

Cpp... c++

[zealous fog]

As a newbie I'll first say making a plane is not very easy

[hollow vessel]

whats asset

[brazen merlin]

For auto leveling youll need to update the roll on tick or something with an interp. Youd probably want to allow it only when youre not affecting roll.

[crystal crown]

that makes sense

also nothing seems very easy 😄 have to start somewhere

[zealous fog]

True

I'll be honest I went into flying ai pretty soon lol

[brazen merlin]

Youve chosen hard mode by working with rotators right off the bat

[zealous fog]

Just warning it can give you headaches lol

[crystal crown]

editing character bp seems miles harder

[icy dragon]

How long have you used Unreal Engine, or gamedev in general for that matter?

[zealous fog]

I made it work

Don't expect it to look great though

I used a lot of illusion to make it look ok

[crystal crown]

i'm having trouble with connecting roll & yaw aswell. they interfere with each other at certain rotations and it goes crazy

[zealous fog]

Theyre not really flying as much as walking but with a higher z value lol

I would focus on 2 axis first

Get that working ok

Leave the z axis for now id say

Feel free to ignore me though

[crystal crown]

i followed a tutorial on yt and got the pitch, yaw & acceleration working perfect. now i need to combine the things but that's where the tutorial ended 😂

[tranquil abyss]

im trying to R&D a inventory and im wondering what the best variable is to store things

Is making an array of actors? maybe a way to do it

as a variable for the player

[brazen merlin]

Yep thats rotators. Default are eulers and youd probably work with quats for less headaches

[glass magnet]

hey conradd

[brazen merlin]

Struct

You can hold all data relevant to the item via array

[tranquil abyss]

those are not variables are they

[glass magnet]

hey conrad i have a question for you

[brazen merlin]

You can use them as vars yes

[brazen merlin]

Yeah go ahead

[glass magnet]

remember last night with my outlining issue

[brazen merlin]

Sorta

Is this graphics related.......?

[glass magnet]

im just trying to apply the outline to a player character

or an actual character class

i have it oulined but it isnt registering that i have my mouse over it

[tranquil abyss]

am I being stupid

The answer is yes, as always but

[zealous fog]

You can click on those structs

And then they're a variable

You literally have it selected 😂

[brazen merlin]

U need to make your own struct

Not the var. The struct asset

[brazen merlin]

Looks legit

[crystal crown]

So you mean that when they interfere with each other it's because of gimbal lock?

[odd ember]

yes in essence

-90 being the same as 270, 360, being the same as 0 etc.

[brazen merlin]

Gimbal lock occurs based on certain rotations, sure, thats more about rotation order. Like what CE is getting at, its that euler doesnt solve rotation values the same. Euler likes to take the shortest rotational route (usually) where as you can rotate in which ever direction in that direction as much as you want.

Its kind like Euler is good at setting rots but not over time rotations

[glass magnet]

ayo

[crystal crown]

so basically i need to set it to quaternions to make the yaw & roll work together?

[glass magnet]

i think i know the root of my problem but i still need help, does anyone know howe to make a character blueprint class clickable?

because the cursor over event only reacts to clickable interface

[brazen merlin]

Thats a different issue and will be one regardless

[crystal crown]

so i'm guessing auto leveling is even more difficult when the rotation is not tracked properly

or is that do'able

[brazen merlin]

Im sure its doable. Rotation math is just hard lol

[crystal crown]

i have searched about this topic everywhere i'm surprised that i found absolutely nothing

[brazen merlin]

Euler and quaternions are math related more than engine related

[crystal crown]

i mean't the auto leveling. I want to make something like EA battlefront starfighter controls

[brazen merlin]

Might be a different term

I dont know much of airplanes

[crystal crown]

i'm a newb so sure can be. no problem. thank you for your pointers and discussion

[glass magnet]

does anyone know how to make a character blueprint class clickable

because im tryin gto use event ActorBeginCursorOver but it needs a clickable interface

unless theres a different way to detect the cursor being over a character blueprint

[last abyss]

make sure these are enabled

[glass magnet]

would i put that into the value under render custom depth

that is what i musing

[last abyss]

I have never used custom depth before, so i'm not sure what to say. but your player controller just needs to have click events/mouse over events enabled to make your actor's cursor over/clickable events work

[glass magnet]

unless i did something wrong it didnt work but thank you for the help anyways

wait

[dusk ember]

i brought this up last time i was in here but didnt really talk about it much; i have a trail on a projectile but it only appears in client mode. anyone have a fix for this?

[last abyss]

by client mode, what do you mean? multiplayer?

[dusk ember]

yeah the client netmode

[last abyss]

you should probably ask in #multiplayer if it's multiplayer related

[dusk ember]

i mean i guess but i want it to appear in every mode

[icy dragon]

Why do you want trail particle to be on server?

[dusk ember]

i want it to appear on everything because i plan to make a multiplayer game. now i put the actual multiplayer part on the backburner, so now i want to at least be able to see the trails when i'm playing singleplayer.

[icy dragon]

You don't need to replicate particles on server, because as far as LAN Party / singleplayer is concerned, host player is still a client that just happen to serve the server role.

[dusk ember]

but why is it only appearing when i'm on the client netmode?

[last abyss]

it seems strange to have it work in client mode, but not in server/standalone mode.. I suppose maybe it depends on where the particle gets activated, or does it get auto activated?

[dusk ember]

its activated when the projectile is spawned i believe

if thats what ur asking

[last abyss]

yeah, is it being auto activated by the particle system or are you activating it in the projectile bp?

[dusk ember]

projectile bp

[last abyss]

can you make a snippet of what the code looks like, or is it just beginplay -> activate particle system?

[dusk ember]

the bottom part is the important part

[last abyss]

the projectile isn't being destroyed on spawn right?

[dusk ember]

no its being destroyed after 2 seconds of being spawned in or it hits an object

[glass magnet]

figured ito ut

kira you were right i did have to activate it but i also had to amke it so the capsule component actually blocks the mouse

before it was just going through the player

thank you for starting the snowball

[last abyss]

did you try to print string the event hit, just before destroying the actor to make sure it's not being destroyed on spawn?

[dusk ember]

its not getting destroyed on spawn because i can see it and when it gets destroyed in game. and this is only happening in the standalone mode.

[mossy mist]

Hi I cant open my project anymore. It fails to rebuild, then tells me to rebuild from source. However, this isn't even a c++ project and I don't have any visual studios files in it. So I try recreating visual studio files but it fails

[dusk ember]

so i made it print out when the trail would end, so its obvious that the trail is being made its just that i cant see it in singleplayer

[last abyss]

very strange how it shows up in client mode, but not in server (standalone) mode.. unfortunately I haven't used those nodes myself so I'm not sure what the issue could be

[dusk ember]

well i appreciate your help, i'll work on this later

[mild ibex]

#umg is prob a better channel

[proper umbra]

didnt even see that mb

yeah thats prob right

[mild ibex]

how would I move, say a cube, as the player character?
I have all the inputs and code and stuff id need to move it, but how would i say toggle moving the separate actor and then toggle it off?

[last abyss]

you would enable input on the other actor (player controller function), and disable it whenever ... happens (where ... is your logic)

[mild ibex]

this is what im attempting to try atm, is use an input to toggle enable input, rn im trying to get a print message to see if it even works and its not as far as i can tell

where Vp_Plane is what im trying to control

[last abyss]

if it doesn't print then either your VP_Plane reference is not valid or it is valid but doesn't inherit from VP_Plane (or isn't VP_Plane class itself)

[gilded venture]

is there any way to have a begin overlap event ignore certain actors/events?

[last abyss]

if you want a specific range of actors that all inherit from the same base class, you can cast to the base class
you could also add tags to your actor class, and on begin overlap using the other actor pin you can check if 'actor has tag' (you can add tags in the details panel of your actor)
blueprint interfaces are another way to do it, using the other actor pin you can check 'does implement interface'

[mild ibex]

with this, on cast fail it is printing

ive tried getting the VP_Plane and the plane pawn

its literally an actor blueprint with a plane inside it

thats all it is right now

[last abyss]

right, but the reference that you are plugging in as the object is not valid, where are you setting that reference?

[mild ibex]

its an object variable with the bp inside it

that

im assuming that by casting, my current object will no longer be controlled and only the plane will be, or at least thats what im trying to achieve

[last abyss]

you should probably change that variable type to VP_Plane, if the only thing the variable will hold is going to be a VP_Plane

[mild ibex]

which, im assuming i need to disable input on the current then enable on the plane

and once enabled it will allow the code in the plane bp to fire?

[last abyss]

Yeah... but is your VP_Plane's parent class pawn or actor?

[mild ibex]

actor

[last abyss]

right, then that is likely what u want to do yeah

[mild ibex]

seems like it worked, i pressed the button then it enabled input on the plane and disabled on the "player" and im assuming id just do the same setup, but in reverse for the player on the plane so it can throw control back

[last abyss]

yeah, actually since you're not changing what pawn you're possessing you can just do a 'get player character -> enable input'

[mild ibex]

😭

im using the vp plane which is this, as the target

and get player controller

[last abyss]

u have to set VP_Plane to be something that is valid in the world

for example, is your plane already in the level on beginplay or is it being spawned in?

[mild ibex]

its already placed in the level

so it should always already be there

[last abyss]

and your player is also in the world, or being spawned?

[mild ibex]

i do have level layers, but the player and plane are on the same layere

also in the world

neither is being spawned

[last abyss]

then you could set the VP_Plane variable to be 'Instance Editable' - meaning you can click, in the world outliner, on the actor that holds the variable (which i guess is your player?) and set it to be the plane

[mild ibex]

ohhhhhh, ok

i see,

now i just have to get it back to the player, which is just the same code you mentioned before

[tranquil abyss]

So I made a struc with 2 different arrays for my inventory, I want to know how to get and set values

if I want to get, set or check Device array index 0

Ik what it would look like in code but not sure in blueprints

Not alot of great stuff on google for this one either

[tranquil abyss]

Maybe it would just be easier to make 2 different arrays

[last abyss]

personally hate structs, but probably using 'Set members in ...' (where ... is your struct's name), unhiding the array pin and doing some voodoo magic

[fervent raft]

I see two nodes in the docs: "Transform (Modify) Bone" and "Set Bone Transform". I can find neither in UE5. Any ideas why? Pls ping if you know :)

[tranquil abyss]

Yeah why over complicate it if Im only doing 2 arrays,

just make 2 variables Ig

[last abyss]

it completely depends on what you're trying to do, like if you're just trying to get the disks you can just do this:

but if you're trying to set values in an array on the struct it gets annoying

[brazen merlin]

The point of the struct was to have it define all information about the inventory item - name, icon, actor asset, type, etc

[tranquil abyss]

the inventory I want to make is basically a List of Items

that happen to be actors

🤔

So you meant make a struct and use that struct to hold that data for each Item

In my case I dont think I need to do that, but for a normal inventory I think it would be almost necessary

[brazen merlin]

This was your original question. I suggested struct. For inventories that is common. Maybe your inventory is not of the norm

[tranquil abyss]

This is what im going for

ignore all the symbols and shit

[tranquil abyss]

yeah Im super new to Unreal and have no clue what im doing lol

[last abyss]

structs are fine, great actually.. just sometimes annoying for example if you did a bunch of things with ur struct, and decide that you need another variable on your struct anywhere that you did 'break struct' it will add that variable (in bps), even if all others are hidden

[brazen merlin]

Might want to look up a tut on inventory with structs as part of your R&D

[maiden wadi]

It's less an Unreal thing and more of a programming one. When you need to bundle properties together, you do so in a Struct. Instead of having two arrays, or maps with same lookup key, you define the entire item in one property instead of multiple.

[tranquil abyss]

I'm thinking the structs would be much easier in code

I know cpp pretty well but for some reasons try to code for this is

well lets just say i try to avoid it

[maiden wadi]

No doubt. But I would get used to structs in Unreal whether in BP or C++. You'd be surprised how much of the engine exists inside of structs.

I've done an entire inventory system in BP using structs before I started learning C++. Just get used to how to modify them with SetMembers macros and don't try to modify copies expecting it to change the array and you'll be fine.

[tranquil abyss]

Or I could be a masochist and make a variable for each spot in my array

Kidding

[remote meteor]

Struct for the inventory information

Separate the item actor entirely

[maiden wadi]

@mild ibex That is a material. #graphics question. But this is what you're looking for. https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphics/Materials/CustomizedUVs/

[mild ibex]

tysm

omg i feel so dumb, literally just search customized in the hecking panel, im so sorry

[empty needle]

Hi, when we're seeing the Flight speed of a pawn. What is the unit of measure for it?

If I see a value of 100 units, I'm thinking it would be something like 100cm/m?

or 100cm/ s?

[maiden wadi]

As in a movement component's Velocity value?

[empty needle]

yeah

[maiden wadi]

Semi sure that is units per second.

[maiden wadi]

In default it'll be cm/s

[empty needle]

Thanks

[gilded venture]

I have an overlap event triggering off of the parent component

uhhh

nani the frik?

[maiden wadi]

Definitely need more context. 😄

[gilded venture]

sorry, so

I'm making a Zelda-like, and the Sword attaches to the PlayerCharacter via a socket

so it spawns, is attached to the socket, and then the rest of the logic lives in the Sword object. In the sword Object there's a Component Begin Overlap that casts to the other actor

it's failing all of the casts, so I did a print string of the other actor to determine wtf it's triggering off of

and it's triggering off of the sword object

[cold sedge]

Looking to build an attribute/effects/ability system, has damage, DOT, status effects and rules to which effects can be on you (CD's), with some action combat elements such as block,riposte, roll/evade. Wondering what are some good resources to look into? Thanks in advance!

[brazen merlin]

Multiplayer?

[cold sedge]

not this project

[brazen merlin]

Hmm still might be worth using gameplay tags

[cold sedge]

just proto-typing and wanna see what I can do

[brazen merlin]

They sorta need cpp. Havent done much with them but so far i havent had to touch cpp with them

[cold sedge]

I've found thousands of hours of them, just not sure who's good. Curious if anyone knows what might be good

[brazen merlin]

Its a big system to make so i dunno, might be hard to find an all-in-one tut/series but maybe they are out there

Is there a game you can reference that is similar?

[cold sedge]

I"m not looking for an all in one, I just need a good base to work off of that doesn't limit me. Some of these use assets that fix you into a corner it appears

I guess a good iso rpg

[devout latch]

I'm making an iso-like rpg - but in full 3D. I have all those things you are looking for.

I have most things in structs and I use a gambit-based system for the computer AI.

[cold sedge]

Thats what I want to do lol

[devout latch]

My gambit system uses about 2 main conditions for my "battle units" and 2 global battle conditions.

Based on the conditions, it attacks...or cures, or whatever.

[cold sedge]

makes sense

Do you have any good resource recommendations?

for learning

like who's the guy

[devout latch]

Is your question how to do it or how to do it in UE4?

There are tons of articles like the FFT BMG which will tell you what you need to do.

Then you'll have to translate that into UE4

[cold sedge]

im in the blueprints sectioni

xD

Just asking who's a good teacher for making a bp rpg system

[devout latch]

There's one by a Tom Looman but it's Blueprint and C++

one = YouTube video

[brazen merlin]

Technically theres alreadty an all in one rpg project on marketplace

Youd have to purchase it obviously...

Or else try looking into the action rpg sample project

[cold sedge]

How much of a worm hole is GAS? I'm pretty green at UE4, just coming back to it right now

[brazen merlin]

Its another dimension

But what you need is what you need

[cold sedge]

I found a video by Reubs on youtube and everyone's raving in the comments about it

[brazen merlin]

Check out all thatd available to you

[cold sedge]

https://www.youtube.com/watch?v=Yub52f4ZUU0&t=264s

[maiden wadi]

GAS is fantastic. But personally I'm waiting til they iterate on it a little. The setup for it is absolutely stupid.

[cold sedge]

I want to get to the level design part so this is a means to an end, I'm leaning into biting the bullet and spending some time on it

[brazen merlin]

GAS is what the action rpg sample project uses

Looks like hes using the same project (i seriously cannot type right now)

[cold sedge]

He is, I just don't want to get into the c++ part of ue4 right now I want to build levels but I want a system in place before I build. I just dunno if GAS is going to divert me for too long

[brazen merlin]

GAS kinda needs cpp 😛

[cold sedge]

I get that, but the amount of time I save creating a system so I can build is what I'm curious about

[brazen merlin]

if i knew the kind of game you were going for, it would help to recommend the right tools

[cold sedge]

arpg

status effects

iso

loot

[maiden wadi]

Don't really need GAS to level design though.

[cold sedge]

You're not keeping up with the convo, all g

[brazen merlin]

i mean.... like neverwinter night? baldurs gate? diablo? dnd? wut

[cold sedge]

diablo camera

action combat

[brazen merlin]

action combat like diablo?

or like dark souls?

[cold sedge]

dark souls

i guess ya, I'm stoned my bad

[brazen merlin]

lol

just saying it would help to know which parts of games would be where

[cold sedge]

Ya I listed it earlier when I was talking to lord

[brazen merlin]

diablo inventory is a bit different than dark souls inventory, for example

can you relink to it?

[cold sedge]

"Looking to build an attribute/effects/ability system, has damage, DOT, status effects and rules to which effects can be on you (CD's), with some action combat elements such as block,riposte, roll/evade. Wondering what are some good resources to look into? Thanks in advance!"

was just grabbing :P

[brazen merlin]

no i read that

[cold sedge]

so a cc system, movement

knockup, knockdown, parry, block

[brazen merlin]

that's still rather vague to direct you, but i guess i can give vague directions

or rather, i have

[maiden wadi]

If you are sticking full BP, you'll have to make your own system mirroring GAS using your own UObject classes and manager components.

[cold sedge]

That's really good to know, cheers

[brazen merlin]

so @maiden wadi whatcha been working on recently?

[maiden wadi]

Amusingly, the topic of this conversation.

[brazen merlin]

oh yeah, which part - learning GAS? working with GAS?

[maiden wadi]

I like GAS. Don't care for the implementation yet. I'll have to learn it at some point, but I'm just making my own simplified ability/affect system.

[brazen merlin]

thats what i ended up doing since i never touch cpp

[cold sedge]

Seems to be the way to go lol

[brazen merlin]

its rather simple though 🙂

yep, works for what i designed out

there's not real inventory though - i did a test with that and i just didnt find it fun for how the game plays

so its all just "on" the player avatar 😄

[cold sedge]

make sense, inventory I'm gonna skip too

[dark crow]

Adding an Attribute to GAS is a a full blown adventure, lmao

[brazen merlin]

yeh....

[maiden wadi]

With spike strips.

And fireballs.

[dark crow]

No one said a pleasant one :p

[jaunty horizon]

Hey everyone I'm kinda new to unreal and I followed a tutorial for wall running but can't implement double jumping off a wall for the life of me. Anything that could be done? I can provide a project file if need be

[jaunty horizon]

Actually I might just restart this whole thing lol

[brazen merlin]

not sure if you're trying to do a custom double jump, but the character class have a jump count which allows multiple jumps while in air

[jaunty horizon]

Honestly I think I should learn the fundamentals of blueprint first

Any tutorials or courses y'all would reccomend

[last abyss]

https://www.youtube.com/watch?v=EM_HYqQdToE pretty much the go-to

[brazen merlin]

A classic. And also any other epic live training is well done. Other tuts are great, but I like how much they explain the concepts and clarify things like: "this is how we intended it would be used" or "do it this way since you can do it wrong"

[glass magnet]

i feel like you sent that earlier kira

[gentle urchin]

You mean who has bound to a given binding?

If you need to know that, perhaps rethinking the design is in order?

Half of the idea is not having to care about who recieves it

Why do you need to know anyways?

[remote meteor]

yeh if you need to know who binds it

its better to redesign it to (probably something like storing interface array and call them from the guy who needs to know it)

[topaz badger]

is there any way to get a reference to an anim bp's owner if its not a pawn?

[remote meteor]

usual get owner node

[topaz badger]

would you use self to cast to an actor?

since get owner's target is actor

[remote meteor]

technically it is possible to know who binds the delegate in the c++ version, there is an UObject Array of who binds it in the delegate, but 99.99% of the time the usage of delegate wouldnt required so.

get owner node in abp should return you the actor it recides in

you can cast to that actor

[gentle urchin]

I figured c++ wasnt an option anyways^^ but yes

[topaz badger]

only option is using actor as a target but ABP doesnt inherit from it

[topaz badger]

ah thanks a ton, weird that searching get owner didnt suggest that

[remote meteor]

if you just need the skel mesh comp

you can use get owning component instead

unreal naming scheme sometimes 😂

[topaz badger]

yeah lol, thanks again!

[eternal furnace]

guys you don't have any experience?

[topaz badger]

check your collision settings. If you need to disable collision to pick it up/attach it to your pawn, instead of disabling collision globally, set it to ignore your pawn

[remote meteor]

hit/blocking collisions only resolve for the component that the moving component is handling

if you need ur "pushing box" to push other stuff

you may need to look into physics collision instead

[topaz badger]

ah thats why it just "worked" for me, ignore my last response

[agile wren]

So I have a physics handle, but whenever I grab objects with it, it clips through walls, and spins freely no matter how much dampening I put on it. Any solutions? Please ping me if so.

[woven ermine]

morning all

or hey 😄

anyone knows of a way to change a material parameter from a static mesh that's in a blueprint at runtime ?

i.e - when it's night i want to increase the emissive value on my material, instead of changing the material to a new, emissive one

I can do this for my actors to change the material -

and it works like a charm with a few of them. but when I have to add like 1000-2000 or so on my map, changing the material on all, at runtime, freezes things a bit

so i was thinking that instead of changing the material to an emissive one, i just increase the emission on my current one; but how ?

not to mention if i have too many of said blueprint and try to change material on them via that function I get this :

[gentle urchin]

Just wondering

Doesnt ISM make sense in your case?

Same material on all of them..

And just one material to update

@woven ermine

[maiden wadi]

Also 2000 loops won't break BP to trigger an infinite loop detection.

[woven ermine]

ISM = material instance ?

[maiden wadi]

Even before the fix for it, which was in 4.26 I think, it took a nested loop of over 5,000 X 65,000

[woven ermine]

if i have a few of them it doesnt trigger that, but as soon as i spawn a ton of them(i spawn the blueprints via the foliage tool), and try to change it at runtime, it gives that

[woven ermine]

i got 5.0

😄

[gentle urchin]

Its not number itself that triggers the loop detection

Its also time

[maiden wadi]

Could be the issue. Try upping your loop detection count in the engine settings.

[gentle urchin]

Foliage actor is just regular actor

You should make an instanced static mesh for this imo 😄

So you place them like you do now in editor,

[maiden wadi]

I still find it hard to believe that updating materials for 2,000 actors causes that. O.o

[gentle urchin]

But a second actor (ism generator) gets all actors of class, creates an instance at the location of the actor), and destroys all of them 😄

[woven ermine]

i can stream if you want

[woven ermine]

its also much less than 2000, i said ill need 2000 at most, but atm im just spawning a few 000

[gentle urchin]

True, it sounds a bit wild. But we dont really know much about what else is going on here :p seeing this raises a few flags, atleast for me

[maiden wadi]

Also UE5. Potential issues with nanite integration having to change underlying code. Who knows.

[gentle urchin]

Yeah anything can happen in ue5

[woven ermine]

this is how many I got when it triggers the infinite loop error

[gentle urchin]

Downloading ue5 source next week to test it 😅

[woven ermine]

but with half of that, im not getting it

any ideas ?:D

[gentle urchin]

Ism ;)

Its the solution to everything these days

That and gameplaytags

[woven ermine]

i need to learn about Instanced Static Mesh i know nothing about them

https://tenor.com/view/thanos-thanos-confused-eefar-thanos-scarlett-witch-scarlett-witch-gif-16041254

[gentle urchin]

You want a new bp that does:
GetAllActorsOfClass(BP_MyPole) -> get transform -> Add Instance(ISM with same mesh) at world location -> destroy actor(bp_mypole)

Collision should be handled in the material aswell

The fake collision. Using one of the custom primitive data fields

Where basically a value -1 to 1 translates to -90 to +90 degree bend on the pole thingy 😄

[woven ermine]

ok I think this will take a while 😄

[gentle urchin]

Focus on the first part first 😄

Ism in new actor, making it replace all actors in the scene

[woven ermine]

i`ll keep you updated

Hello , i want to ask the Unreal developers about their opinion in blueprints . Are the blueprints mostly for artists ? Iam already in game developing worked with Unity and Godot , but am looking to give a try at Unreal Blueprints .
And my second question is, have anyone tried the following courses from udemy and what is he/she opinion .
Unreal Engine 5 Beginner Blueprints: Make your first game!
Unreal Engine Blueprints - The Ultimate Developer Course
Unreal Engine Blueprint Game Developer (bestseller from ben)

[spark steppe]

i think the mix of BP/CPP is optimal

if you want to make advanced things you will hit the limits of blueprint

[echo salmon]

@spark steppe Ty ben .

[spark steppe]

however, they are a good place to start to get familiar with the engine, and imho they are also pretty neat for prototyping

[echo salmon]

@spark steppe what do you think its the best way to get into it ?

[spark steppe]

no idea

just start 😛

[echo salmon]

[trim matrix]

Is it possible to create a game like this in the unreal engine?

[gentle urchin]

With the right resoruces, sure

Annoying flickering tho. Would just do fog of war kinda thing

[river pine]

HI there, i have a hud progressbar, but i need to set empty 0 and full progress is 30... somehow cant do it. only goes o empty full 1

[zealous fog]

I can recommend the gamedev.tv courses

[gentle urchin]

Out range 0 to 1.

[wild turret]

Anyone know how to get a random socket from a specific bone on a character mesh?

[subtle isle]

Save the sockets from the specific bone into an array and grab a random one from there?

[river pine]

Hi do you know where to set it up?

[spark steppe]

in your map range node

[river pine]

teh rangge is 0 to 30 which i need

[spark steppe]

just change the out range A to 0 and out range B to 1

[subtle isle]

I got a little problem on my end as well, this had been working up until now

I used to be able to move camera up and down but ever since I made a main menu it stopped working and the camera only now moves if I move the camera while holding down the mouse button

[spark steppe]

you probably changed the input mode of your player controller to something weird

[river pine]

i set it now its stoll 0 emptz 1 full

[subtle isle]

yeah I think it has to do with this node

but I am unsure how to set it back

[spark steppe]

@river pine make a screenshot with the setup now

[subtle isle]

after he is out of the main menu

[spark steppe]

set it to locked include initial mouse down or something

when the menu is closed^

[subtle isle]

only got these options tho

[spark steppe]

@river pine in range B has to be 30

[wild turret]

Struggling with the first bit... (novice blueprinter here...) I can't find how to get a specific bone to be able to feed into this node (which is what i think I need to do) :S

[river pine]

tried that too... wierd dont work

[spark steppe]

and your possesion int goes from 0-30?

[subtle isle]

Im in the same boat as you friend, in theory I think that's how you would do it but I am not sure how to set it up exactly

[spark steppe]

now you would need to know their parent bone, look if there's a node like "get socket parent"

[river pine]

yes

or do inend to set up the int somehow too?

[spark steppe]

no, it should work

[river pine]

strange

[spark steppe]

put a print string on your int, to check if the value is correct

[hoary spruce]

hi

[river pine]

yes i have its counting everytiem 1 up if i press spacce @spark steppe

[hoary spruce]

Can Anyone Help Me?

[trim matrix]

Hello, I'm making a VR project and i have a wheel that i can grab the handle and turn. but i cant figure how to convert how much i turn it to moving an object along a spline. like if i turn it in one direction the object moves out the spline. and vice versa... i hope it makes sense

[subtle isle]

I was silly, didn't know there was a node called set input mode to game only mb

[hoary spruce]

Can Anyone Help Me?

[subtle isle]

Whats your question?

I asked a question just like yours a few days ago and I was sent this link xD https://dontasktoask.com/

[hoary spruce]

I designed an AI for the horror game. The monster has to wander around randomly and follow me when it sees me but the beast never moves

@subtle isle

[storm vigil]

Hi there. may I ask what is the logic or nodes needed to determine if the player is looking down or looking up? Thank you

prob get the controller pitch?

[icy dragon]

Get Control Rotation, if you fetch from character.

[gentle urchin]

So its working ? 👍

[storm vigil]

yeah thanks got my player camera manager and its control rotation.

[river pine]

nope its fill up full when gets in 1

[gentle urchin]

And your ranges is now 0-30, 0-1?

[hoary spruce]

pls anyone help me

[hoary spruce]

pls

[timber knoll]

also "designed AI"

[trim matrix]

Would anyone know how to implement a really non performance intensive sorting algorithm to sort an array in blueprints?

Like solely blueprints, not C++?

There is no built in sort node?!

If there was I wouldn’t be asking lmao

[timber knoll]

there is for all base types

[trim matrix]

Wait the fuck do you mean

Was this added recently?!

I’m so confused, I don’t have this in my event graph even with context sensitive off

[timber knoll]

oh no it looks like that's just a common plugin for blueprints

but really if you're looking for something performant, you have to go C++

[trim matrix]

Oh I can’t use plugins as I am modding a game

Yeah but I can’t use c++, or any plugins

My Limitation is to only be able to use pure bp

How, and is this faster than bubble?

Huh ok

[odd ember]

🤔 🤔 🤔

[trim matrix]

Yeah lmao

Good for small datasets tho ig

[odd ember]

I've always been a fan of mergesort

but maybe that's just me

[trim matrix]

Ok well would anyone know how to implement this new sort thing?

[trim matrix]

Oh back when I studied CS that was my fav too lmao

How 😂

That’s like saying “You can bake a cake, by baking a cake.”

But alright 😂

[odd ember]

well no they actually give you the instructions on that page

in pseudocode

[trim matrix]

Oh shit

Wait really?

Zamn

[trim matrix]

everyone ignored me

[trim matrix]

Calm child

Alright well thanks guys 🙂

[trim matrix]

why did you call me a child? I did nothing

[trim matrix]

Impatient child tendencies lol - but it was half a joke so chill lmao

[odd ember]

what's your opinion on mergesort

[trim matrix]

thanks at least you didn't curse me for no reason

[odd ember]

uhhh perhaps

I'm not so familiar with the std framework

good to know

I've never heard of introsort

but I like that it switches based on the data

sounds like a good candidate for a PQueue sort as well? kinda?

[faint pasture]

True Chads use bogosort

[odd ember]

what a PQueue is?

🤔

well yeah but then initial sorting for a PQueue is still a sort

afaik usually insertion sort

I don't know, I've never used any of this for wobsites

I have used PQueues before though

it is a priority queue

just shortened

to 🇵Queue

fair enough

[stiff raptor]

Get random reachable point radius is always returning the same value, radius is 100, origin is the location of the actor itself. What can be the problem?

[odd ember]

maybe there is only one point in reachable radius? what is the value?

[stiff raptor]

the value isn't fixed for everytime. Everytime I run the game, the character at first moves once and then the value is same as the location where it moves so the character isn't moving anymore. After moving once it stops.

[stiff raptor]

yea, I'm using an event. On both success and fail the event is being called once again. On runtime, I did checked that it being called again.

now dat ya said timeline, I might try dat.

[mortal cradle]

Is it a good or bad practice to check "isValid" before casting on overlap? So the cast would happen only on the first overlap

Sure but the point is to avoid an unnecessary cast if the reference is already present

Oh wait

you mean that in the cast there is already isValid check so it won't really cast again?

[zealous fog]

If the reference is already present, its already loaded in so the cast won't load it

[mortal cradle]

Got it, thank you

[zealous fog]

Casting isnt bad

It's there for a reason and used a lot

Just easily abused

I narivize my BPs so it shouldn't cost more then or does it?

Which is why in sticking with 4.27 until I learn C++

Performance gain was very significant

Well my game is pretty much unplayable without it so I'll take em

[trim matrix]

wait if I can create a game like this on unreal, how do I create it? does not have the blueprint "move window" in unreal

ok

[trim matrix]

Sorry to bother @trim matrix but would you have an example or something to do with this quick sort thing? As I am not familiar with it it is quite hard lmao

FCK

This one mod kit requires pure bp tho lmaooo

Hm

[gentle urchin]

https://forums.unrealengine.com/t/c-quicksort-algorithm-to-blueprints/117907

[trim matrix]

Hm

I don’t use macros anyway lol

Is it literal,y just this

Like is this the exact pseudo code

Huh ok I do have a CS background lmao - shouldn’t be that bad

Alr thanks man

[mortal pilot]

counter strike background always helps

[crystal crown]

anyone good with rotators?

[pliant tendon]

How should i play music tracks in order with gaps in between

I want ambience to be constantly playing, and music to play over it

But, track 1 should start instantly, then pause, play track 2, pause, play track 1

so on and so forth

[snow cradle]

Hello; is there a blueprint/c++ function to get number of triangles drawn in the frame? I notice that this is available in stat unit @runtime even in shipping build.

[odd ember]

what's your issue?

[odd ember]

you need to write your own system for that

maybe better to ask in #audio

[zealous fog]

Make a looping sound cue

Easy way to do it

[crystal crown]

still trying to figure out the auto leveling rotation

[odd ember]

I don't know what that is

[crystal crown]

i have a pawn. when i roll it i want it to return to starting rotation. i need to track it somehow etc

[odd ember]

what kind of pawn is it?

[crystal crown]

like a plane

[odd ember]

set the starting rotation to a value, do your rotation stuff. set it back to the starting value?

[crystal crown]

currently when i give input it stays at that rotation

[odd ember]

yeah so before you invoke the function, set the rotation you currently have to a variable

then you can use that rotation to return to later

[crystal crown]

hmm okay

could you make me an example. i'm still newbie

currently im tracking only the speed

not rotation

[odd ember]

just.... add a rotator variable?

click new variable > rotator > name it something (or don't) and add it to your chain of events

[pliant tendon]

I did, but how do i add pauses in between the tracks

[odd ember]

this is why I said you need a system for this. I think asking in #audio is your best bet. they'll know how to make music crossfade between channels appropriately

which sounds like what you want

[pliant tendon]

I asked over there, but no, im pretty sure crossfading is the exact opposite of what i want

i want them to have pauses in between

[crystal crown]

look at meta sound tutorials

[odd ember]

in either case you'll be wanting to speak to those people as they will for sure know more about how to make it work correctly. my understanding is that you need to remember where along the music tracks you are etc.?

[pliant tendon]

no

I want to have music tracks play, and have pauses in between

[zealous fog]

Look up how to delay in sound cues

[pliant tendon]

But delay adds a delay to the first time played too

[zealous fog]

You csn add a delay after too I believe

[pliant tendon]

it will look like this

Delay -> play track 1 -> delay -> play track 2

i do not want this

i want

Play track 1 -> Delay -> Play track 2 -> Delay

[earnest tangle]

You can just set the nodes in that order in the sound cue, no?

[pliant tendon]

No

[earnest tangle]

Why not?

[pliant tendon]

Because you simply cant XD

it wouldnt work for a looping sound

[zealous fog]

You can also just add delays to your .wav

[pliant tendon]

it would look like

[zealous fog]

If you wanna make it realy simple

[remote meteor]

question is

are those track fixed

[pliant tendon]

Play track 1 -> Delay -> Play track 2 -> Play track 1 -> Delay

[remote meteor]

or dynamic

[zealous fog]

You're missing a delay I think

[pliant tendon]

sorry i dont know whats dynamic/fixed

[odd ember]

exactly my point

[remote meteor]

because you can always just use

[pliant tendon]

because its looping

[zealous fog]

Otherwise you can just delay track 2

[remote meteor]

concatenator

[pliant tendon]

Holdup i don't think you guys are understanding

[odd ember]

if it's a single instance of these things you can make track > delay > track > delay

but if you want something that is changeable per level and replaceable you need a system for that

[zealous fog]

If you want this to happen delay track 2

Because you didn't put a delay between 2 and 1

That's why I said I thibk you're missing a delay there

But like I said, you can put a delay after

[pliant tendon]

Track 1 ->
->looping
track 2 -> Delay ->

[pliant tendon]

But then it will take the delay time to play the first time

[zealous fog]

...

I'll say it one more time

Put a delay at the end

[pliant tendon]

it will be

Delay -> Track 1 -> Delay -> Track 2

[zealous fog]

Instead of at the beginning

[pliant tendon]

But then it will play the delay again when you loop it

are you serious homie?

[remote meteor]

i dont think this is very hard to figure out

or to be precisely

[pliant tendon]

And now it wont pause when it loops. Between track 2 and 1

[zealous fog]

You want the delays to happen right

If you want a delay between every song

Except the first time you play the first song

[pliant tendon]

Exactly

[zealous fog]

Then put a delay at the end....

Think about it

[pliant tendon]

But you cant just put a delay at the end

[zealous fog]

Change the wavs

Like I said

Most simple solution

[remote meteor]

sry

[pliant tendon]

Oh now i get it, put a delay at the end of the wavs not BP

[pliant tendon]

Or this, thanks

[zealous fog]

You can do it in BP

But its apperantly hard for you to grasp homie

[spark steppe]

isn't there anything that fires when playing a track is finished?

[pliant tendon]

It isnt

[spark steppe]

putting everything through delay looks like a weird solution

[pliant tendon]

you just dont explain well.

Anyways thanks alot everybody

[zealous fog]

Ok

[thorny rover]

Hello! Does anyone know why rotation in level editor values are different than when printing them?
My rotation value is set to be 0;0;-130

but when i print them it says

CameraActor3
Rotation P=-13.388420 Y=-117.170578 R=-5.788363

i use "get camera view node"

[pliant tendon]

Not here to argue

[odd ember]

camera view rotation != camera rotation

[thorny rover]

oh no.. :(

[crystal crown]

i tried this but this sets the rotation based on world (resetting pitch and yaw aswell) or am i doing something wrong

[odd ember]

exchange it for a float variable and just take the roll value of your rotation

[zealous fog]

Yeah me neither so sorry if I was a bit rude but if I'm trying to help and if you're gonna be replying "are you serious homie" it feels like you don't want the help 😅

[pliant tendon]

Oh sorry if you took that as rude

Not very good speaker anyway and tone doesnt go good with text, my bad.

[zealous fog]

It's alright

Hope it works out

[pliant tendon]

Thanks

Good luck to you too 😁

[crystal crown]

woot i got it to work, doesn't reset pitch & yaw anymore

[odd ember]

amazing innit

[crystal crown]

now i need to make it return to position smootly, using lerp? currently resets instantly

[odd ember]

lerp and a timeline could work

FinterpTo or RinterpTo could also work

depends on your use case

[pliant tendon]

This works great, thanks alot

[shut thicket]

Noob here. can you use a auto material and procedural foliage spawner at the same time? Since the auto material is one layer i cannot seem to assign certain foliage to my layers. Not sure if there is a way around this. Thanks

[gusty axle]

this image can make you feel physical and mental pain and can traumatize you

digging through 4 year old project is fun lol

[simple moss]

is there a way to ignore the remaining function if the target actor no longer valid?

[spark steppe]

just add an isValid node?

[simple moss]

it's in the pending execution list then the target got destroyed before it finished, so the error come up after I stop the play

[gentle urchin]

An actor

Cannot become invalid

During a function call

Either it was from the start, or it wont be in the end

[gusty axle]

isValid an ultimate solution

[simple moss]

is there a way to constantly check if the reference array is valid?

for now I only have events begin overlap and end overlap which isn't cover in some conditions

I need the custom event to check it

[gentle urchin]

Sounds like some logic needs fixing...

[simple moss]

I have no idea

[gentle urchin]

Stuffing isvalid everywhere sure gets rid of errors, but doesnt magically fix the underlying potential issue of the event calls

[odd ember]

defensive programming is not a solution

only use IsValid in cases where you cannot be sure 100% of the time that the value is null

[simple moss]

the value is constantly null

[gentle urchin]

Which is the primary issue

[simple moss]

why?

should I try to implement the default variable for the array?

[odd ember]

if the value is constantly null then maybe... ensure that the value isn't constantly null?

[simple moss]

it's supposed to be no variable because it's filtered list

[odd ember]

what are you trying to do anyway

[simple moss]

I guess the way out is just implement interface and notify when the condition met

[odd ember]

interfaces aren't magical either

[simple moss]

well I don't have alternative

[odd ember]

what are you trying to do?

[simple moss]

kill enemies and notify if it's killed

[odd ember]

can you show your code?

your kill code?

[simple moss]

the problem is pending kill

so I'll try to find a way to work around then, thanks for trying to help

[odd ember]

sounds like the issue is in your code then 🙂

[gentle urchin]

Sounds like destroy actor is called before doing more logic to said actor

[simple moss]

well I fixed it by using lifespan instead of just destroy, then set visibility off

[chilly geyser]

does get all actors of class include children?

[gentle urchin]

Exactly.

[subtle nova]

Hopefully quick question. Does anyone know how to reference an input binding? Trying to make the button prompts match what the binding is even if the player has modified the controls.

[spark steppe]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Settings/GetActionMappingbyName/

bottom right

[subtle nova]

Fantastic, thanks!

[spark steppe]

but i think they aren't all exposed in the property matrix

[chilly geyser]

How do I enable gravity but not physics? I.E. not have anything affect the actor except for gravity

[spark steppe]

there

they aren't all available in the property matrix for whatever reason

probably because most of them requires rebuild of LOD meshs which doesn't work through the matrix?! no idea

[zealous fog]

Gravity is physics

But you can check the enable gravity

And have the simulate physics uncheckdd

[chilly geyser]

I tired that, it wont move if I do that

I just want it to fall to the floor, without being able to move from that spot

[zealous fog]

Then you have another problem 😅

Just checked and that's how my character is setup

[chilly geyser]

ill try again

[zealous fog]

Probably your gravity is too high

So you are moving but accelerating extremely slowly

[zealous fog]

Or the character is too heavy

[gentle urchin]

Or a bunch of other #legacy-physics parameters

[zealous fog]

I say probably but I mean maybe

[chilly geyser]

it works as intended, but after the die lands, I want it to stop moving and only have gravity affect it, so when its reset, it goes back to start position and falls back to the ground, but i dont want anything to be able to move it while its falling

so fall strait down

regardless if something hits it while its falling

[gentle urchin]

Implementing your own gravity is also an option

[chilly geyser]

@zealous fog can you lock x and y movement on an actor?

[zealous fog]

Whenever you change the location, get current actor location, split the pins, and put those axis directly into the setlocation node

You can then adjust the Z-axis before plugging that one in

(or use a makevector node to make it look prettier)

Or interp instead of setlocation

[chilly geyser]

messing around with this to see if i can get it to work

it works but I need to figure out how to change it from 2 directions to just 1

[zealous fog]

Oh didn't know that node exists

[eternal reef]

Is there a simple way to increase the size of, lets say a Static Mesh Cube, along an axis only in one direction?

[versed sun]

i dont think there is a 1 node "simple", but you can adjust scale and then change the Relative Location to line up with what you started with

[tranquil abyss]

So I got multiple items in a array and im trying to display them all with a simple text widget

only the first String/text in the array is showing

[spark steppe]

that's because you return on the first iteration

do you want one long string with all the names?

[gentle urchin]

Scale in singular axis..?

[zealous fog]

Can someone help me understand how this works?

Output

all singleplayer btw

omg....

nvm

I just got it

I am an idiot

lol

[tranquil abyss]

ah, and For the time being just a
List
like
This

[eternal reef]

huh?

[gentle urchin]

Integer division is nice like that

Along with %

Modulo

[gentle urchin]

Just scale the mesh?

[versed sun]

https://www.screencast.com/t/YHXLcrAg Do you want this?

[eternal reef]

Sorry for the delayed answers, yes exactly that @versed sun

[versed sun]

this works on a 1m cube

and only for positive scale

[eternal reef]

Oh well thats definetely what I would call simple, thanks alot (:

[spark steppe]

you would do something like this

create a local string variable in your function named output string

in the loop body append to the string, and update it with the set node, and on completed you can return the output string (converted to text)

[versed sun]

replace the "Mesh Size" with how big your mesh is (Not the scale)

[eternal reef]

Ill check in a min whether it works on my particular issue

[final skiff]

Anyone know of a way to get Materials to Blur based on distance from the camera?

[odd ember]

change its pivot location

[odd ember]

probably a better topic for #graphics

[final skiff]

alrighty thanks

[stiff pilot]

Hello, is there a way to use editor thumbnail of static mesh as 2d texture? I've searched everywhere for that and couldnt find answer.

[cobalt gulch]

Hey guys

How can I use variables to check if a player is playing a certain operator/character

[odd ember]

there's a thumbnail edit mode in the asset browser

[zealous fog]

You set the current operator as a variable (Can be just a string text) and you can check if CurrentOperator == certain Operator

[cobalt gulch]

Ok, could I check this in a branch?

Or is it more like currentoperator == operator true

[stiff pilot]

@odd ember i meant can i use that thumbnail as texture 2D in widget, to be more exact can i get it dynamically either from object>static mesh or reference path

[zealous fog]

I would disable collision

And then add an impulse

[zealous fog]

Yes

[cobalt gulch]

Sorry if im stupid but I can only see the boolean innput

[zealous fog]

This is quite basic so what I would do is go to the unreal learning website and start going through material on there until youre comfortable enough with the engine to comfortably understand branches and bools

Can also look into how tags work

[cobalt gulch]

ok lol

Could you show me an example if possible

I think i'm just not understanding how to put it together

[zealous fog]

you can find lots of information on this online

[cobalt gulch]

I couldn't find anything 😦

[zealous fog]

those videos are a good starting point

[cobalt gulch]

Alright thanku

So it is possible to make a tag with a string

[trim matrix]

Here I just used min/max functions with my own logic to sort it. Now it can only be efficient with small-med datasets with no more than like 1k items (ig), but it is efficient in it's own way.

And this is Pure BP too, no C++ or plugin bs required 😄

[odd ember]

well at least n^2 + addunique cost. I'm sure it has to check for uniqueness somehow

[trim matrix]

I don't understand big O notation lmao

But what I do know is that it is scuffed, but I am only using like an array of 20 diff ints with a max value of like 1k

So it's really fine for my use case

For a pure BP solution aswell - it is more than adequite

[odd ember]

how did you study CS and not understand big O

[trim matrix]

I didn’t do it at a higher level

Noob question here, I am currently executing the loadlevel by name node - and I have a player start defined on the target map - wierdly the map loads and my player is flying through the abys

I did it in high school and at an a-level

[tawdry surge]

Big o is basic cs

[trim matrix]

do I need to set the player start or something on begin play on my target map ?

[tawdry surge]

Right along sorting algorithms

[odd ember]

your player might load before the object it is standing on?

or maybe it's collision settings

[trim matrix]

hmm

CE can I show you what I have ?

[odd ember]

can you test it first? with breakpoints?

[trim matrix]

I have 0 nodes in my target level

and my target level has a player start actor on the ground

[odd ember]

if you play the level regularly does it work?

[trim matrix]

yes

that is the target level

regular level

but the player literally spawns in the middle of nowhere

but the map is loading becuase I can print a message from it and I see that

[odd ember]

no idea. probably not blueprint related. I know people have had issues with this before

[trim matrix]

very weird 😦

@odd ember it was the BP - it is not Load Level but Open Level

[odd ember]

well no. that's just hard loading the level

[trim matrix]

ok

[odd ember]

it may get around the issue but it doesn't solve the problem

[gentle urchin]

Gotta love them bandaids

[maiden wadi]

Also should drag off of Introani and BindToAnimationFinished instead of using a delay.

[past jungle]

Hello.
I'm trying to create a player interaction system where every tick, a "Player Target" is determined, and when the player controller receives input, it notifies the Player Target so it can handle the input based on its class. I keep running into the same problem where I want the Player Target to be generic enough to accept any actor, but I want different types of actors to handle the player input differently. For example, one way I tried to solve this problem was to create an interface with functions for player input so that every actor subclass I create can override the function differently. But that didn't work, because I can't call the function without first successfully casting the Player Target to a class that implements the interface.

Probably, I could create a subclass of actor called "Interactable" or something. But I'm trying to use actor components rather than inheritance for behaviors whenever possible. Does anyone have any advice here?

Hold, please. I have to clean up my various failed experiments

Oh. I think I was trying to use the interface call node instead of the message node. Thanks! I guess I just needed a smack up-side the head.

[trim matrix]

If I had a really simple sorting algorithm that works like this (image 1): https://cdn.discordapp.com/attachments/927669839693234247/938140526450974740/unknown.png

How would I be able to go a step further and just sort an array of a struct which looks like this (image 2) https://screenshots.foxy.rip/ZmDmRzht ?

Like I would want to sort the struct array by kill count

Heh?

How

How would I do that?

Uh

Oh alright

Makes sense thanks, lemme try and see if I can accomplish that :)

💀

I am using like 4 elements in an array chill tf out

I was being like really precautious

But at this point, idgaf so it's fine lmao

Right brb while I implement it lol

I already know blueprint. Now I want to learn c++. Do someone suggest some tuorials or courses (like udemy course)?

Youtube

And only youtube, SO and shit

Never pay for things that are free lol

Start by learning the basic syntax outside of UE4, then get more advanced - and then as time goes on start to learn the C++ UE4 syntax after you have a grip of the syntax

[timber knoll]

youtube is fairly bad for UE C++ imo

[trim matrix]

Eh

Ig

But it will get you good on the syntax part

(before you go into ue)

And then there is the amazing UE4 wiki which kinda just replaces the C++ docs for UE4 lmao

Lorash

Would that be good to get the min struct item?

(based on the kill count)

Or would there be a more efficient way of doing it

I mean in terms pure BPs

Alright, stop there - that's all I want to know due to my limitations

Thanks

Is my thing which I am doing rn better than bubble sort?

Or would bubble sort be better

Why do you have to be so toxic 😂

Just bear my limitations in mind, and just understand that for what I am doing it really does not fucking matter lmao

[gentle urchin]

Why not sort it on the go?

[trim matrix]

What do you mean Squize?

[gentle urchin]

Nvm. Thought it was something else

[trim matrix]

Oh alright np

[gentle urchin]

Could perhaps be done tho

[blissful grail]

4 items, I wouldn't even bother asking if what you're doing is fine.

It's 4 items.

[gentle urchin]

Yee

Barely needs sorting

[eternal drum]

How do i make my bp rotate around an point istead of the center?(How do you change the location of the center?)

[trim matrix]

What's it to you

[blissful grail]

You can also change the pivot point temporarily

Chris Murphy (@HighlySpammable)

If you Alt + Middle Mouse click an actor in #UE4 you can temporarily change the pivot to rotate/translate it. Pivot resets when selected again. Super useful when trying to line stuff up and some artist designed it with a pivot for another purpose in mind! https://t.co/bMtr57uD5a

[eternal drum]

Ok but how would i change the point that it rotates on?

[trim matrix]

Lorash do you know why this doesnt work: https://blueprintue.com/blueprint/17_doh4r/

Thats what it is outputting

Default var values

It’s the same principle and design as my other code, just using structs

Like you said

Huh?

How tf

That’s an output node…

Bpue doesn’t show them well

Yh

Hm

I could use a for loop

But like

It should work anyway, right?

Hm

Alr

I’ll try and do it with a for loop using th last index as the array length - 1 then

R,right?

Alr I’ll test it in a sec

[odd ember]

what kind of monstrosity are we implementing today?

[trim matrix]

Lmao

Scuffed sorting of a struct for an inventory system

[gentle urchin]

Min from struct array?

Custom fn?

[trim matrix]

Min value of one of the values in a struct

Done that part

[gentle urchin]

Ah

[trim matrix]

Just need the sorting part tested and working

[gentle urchin]

One of the values sounds specific

[trim matrix]

Yeah…

Shit but simple to implement so idc

[gentle urchin]

Simple yet not working 🙄😏

As pointed out , manipulating array you're working on is not a great idea

[trim matrix]

Yeah dw gonna try out the for loop now

[odd ember]

oh we're still on that?

wouldn't it be simpler to expose a call to something TArray.sort()?

[trim matrix]

Well that doesnt fucking work either lmao

Uh

[faint pasture]

We still trying to sort around here?

[trim matrix]

No

No I need that for the whole basis of the logic

[gentle urchin]

Imagine if this was not simple to implement

[trim matrix]

The logic is that it looops for the amount of the array, and then the smallest items are removed one by one until there is one item left

Thus solving it

That’s the logic behind it anyway

[trim matrix]

I mean all of it works correctly when I do it with just an integer array

So why the fck does this not work 😂

Alright fine

[odd ember]

btw

[trim matrix]

I’ll do it with bubble lmao

[faint pasture]

What are you trying to do?

Classic off by N error

[odd ember]

cah-lu-a-sic

[trim matrix]

I have an array of structs and inside the struct it has a player name, kill count and max kill streak. I want to sort the array of structs by kill count and I can only do it in pure bp no cpp or plugins whatsoever

[faint pasture]

How many structs max?
