[lime yoke]

I don't know if having an input of the class character could be considered equally to a "cast" to a Character class.

[zealous moth]

@lime yoke it is.

[lime yoke]

Thank you.

[lofty rapids]

i mean at some point when you call this, you need to cast to that anyway right ?

[zealous moth]

@sharp ferry you would need tonuse a material parameter collection and a post process effect.

@lime crow you can also type ~ to get the cmd prompt and type 'fps' and enter. Toggles it

[lime crow]

Ahh thats handy, thanks

[visual ember]

cast is a virtual problem. the reference to an asset iscan be a real one

[mental bobcat]

I have a stats struct that is in a Data Asset.

during runtime, I modify the stats struct when I pickup a power up.

The changes are persisting/updating the struct in the Data Asset even after runtime ends.

Is that normal or a bug of some sort?

[lofty rapids]

so you alter the data asset in runtime, and it changes the valueu when you go back to editor ?

[lofty rapids]

"Data Assets are designed to be read-only templates"

[mental bobcat]

only altering the stats held in the struct on a spawned in during runtime actor that has the data asset as a variable. and yeah the values are staying changed

[lofty rapids]

does it happen in PIE ?

[mental bobcat]

yes only tested in pie so far

excuse the spaghetti here lol

[lofty rapids]

right so i'm guessing you just want to update the stats during runtime and not keep these right ?

[lofty rapids]

what bp is this on ?

[lofty rapids]

you have stats on the weapon as a structure, did you set them to the values from the data asset to begin with ?

[mental bobcat]

yes only keep the stats during runtime. but I'm building out a bigger system for weapons in general.

the modify stats is on the weapon base

[lofty rapids]

instead of weapon data asset -> item, set the item from the character ?

[lofty rapids]

so your updating player stats here ? by the amount in the data asset ?

and you want the player stats to update but not the asset ?

[mental bobcat]

no... weapon stats

player stats are being added to the weapon stats

[lofty rapids]

instead of weapon data asset -> item, use weapon -> stats

[lofty rapids]

so your currently adding the data from the asset to the player stats, which you probably want the Stats variable on the weapon instead

and anywhere you reference the asset to get the data, reference the weapon

get the data from the asset when you spawn the weapon

and set the original stats

then use the variable on the weapon

[sharp ferry]

i crated it but i would like to make it more uniform

seems like i have too much lights. i tried to play with paramentres

i would like to make less posterizaztion and more darker i show u my material

[mental bobcat]

this is setting the stats on the weapon. not on the player. so its not quite what you're saying. I'm taking the players stats and adding them to the weapons stats then setting the weapons stats.

[lofty rapids]

this is actually setting members in the asset, this is the problem

[sharp ferry]

chat gpt was suggesting me only to set B6.0 AND ON divde 6.0 too. i had to increase because if i set 6. on both its totally dark

then it suggested me a ramp node but i've tried to add and i cant do a thing with it idk

[lofty rapids]

or wait i'm confused af, lol so weapon data asset is your data asset ? or your actual weapon reference ?

[sharp ferry]

sorry i should talk of this in material

i thought i was alrady

#materials

[lofty rapids]

by this i mean what is Weapon Data Asset here ? what is it refeerencing ?

the name is misleading if it's the actual weapon

[mental bobcat]

hmm yeah, I think its over complicated. I may just nuke some of it and simplify

[lofty rapids]

what you do is take from the Data Table, and put it in a variable where you can access it

then just use that variable

and it won't effect the original data

[mental bobcat]

don't want to use data tables but sure

[lofty rapids]

i meant asset

what is weapon data asset ?

[mental bobcat]

yeah, got what you were saying, just didn't want to use tables lol

[lofty rapids]

well you don't need tables i thought you were using already

it's not complicated, it's confusing what your saying

[lofty rapids]

i meant Data Asset

[lofty rapids]

i meant asset not tables

[mental bobcat]

my thought was to make a weapon base blueprint, store a Primary data asset in it that could be changed out as needed

[lofty rapids]

^...

[mental bobcat]

WeaponDataAsset = PDA_Weapon but I think, like you said, its the problem because its editing the main one, not a variable

[lofty rapids]

where do you set Stats on the weapon is that the only spot ?

[mental bobcat]

there and the modify stats function

[lofty rapids]

because your modifying the asset is the problem most likely

make a copy of it in a variable when you load the game

[mental bobcat]

I didn't know you could do that

[lofty rapids]

to use instead

[visual ember]

I was avoiding data assets myself, so know very little, but I don't think they get edited permanently when packaged, only when you run from editor

[lofty rapids]

ya i also read that

[visual ember]

I'd check packaged game first

[lofty rapids]

still annoying to mess with trying to play test

[mental bobcat]

is that an engine bug maybe?

[visual ember]

UE works in mysterious ways

[mental bobcat]

I have UDN/Epic Pro Support so I'd happily put in a ticket for it if it is a bug

[lofty rapids]

they are meant to be read only

so you shouldn't be changing them anyway

[mental bobcat]

technically only changing the struct haha

But I guess I can just put the struct in the blueprint

[lofty rapids]

use the data asset, to load data into somewhere else

then modify that value instead of the actual data asset

you could put it on the weapon that would be if you don't destroy it

if you destroy it, the data is lost

[blissful grail]

const-like data belongs in the data asset
runtime-like data belongs on an actor/object.

[lofty rapids]

i would probably have a map of weapon id to stats struct

and just alter those, probably in game instance

[blissful grail]

I have a data table that has the weapon stats themselves. Then a data asset with the row handle. Then I have buffs/debuffs that apply based on those. So say I have a buff that increases the my magazine capacity by 10%. The DT will still say 30, but when I am getting that value, I'll check for the buffed value. So GetMagazineCapacity() would return something like Row->MagazineCapacity * buff (how the buff actually happens doesn't really matter, that's why I wrote the pseudocode like this)

[mental bobcat]

hmm neat, the weapon stats only need to be changed during runtime

making a vampire survivors-like

[blissful grail]

So my BP_Weapon has a reference to the data asset that has all the other stuff (like the vfx, sfx, meshes, etc...). Then I access the row through the data asset.

To create a new weapon, I just need a new DA and new row in that stats DT.

[lofty rapids]

then just load em up with the data assets information

then stat lookup time is really quick with a map

O(1) ftw

[dusky meadow]

Hi why does my character still crouch while in the air ?

[high crescent]

What exactly are you asking? Why’s it crouching after you jump? Why’s it crouching when you’re falling? Give us more details. Why wouldn’t you be able to crouch in-air? It’s a feature in many games like Halo

Id assume your “Can Crouch” function has nothing blocking crouch when you’re in the falling state

Either way, we dont really know enough about your project to answer

[dusky meadow]

The can crouch is a stock ue4 function also the issue is i dont want the player to be able to crouch in midair

Also if I manually check that the player isnt falling or flying it works as intended so i dont know why that function isnt working

[lofty rapids]

i would just suggest using isfalling and call it a day

it could be a bug, or maybe it was designed that way, but the issue is doesn't work either way

did you try a reboot and it still doing the same thing ?

[dusky meadow]

Okay thank you for the advice and i will reboot now

It seems like that function is just bugged will use is falling instead

[sick sky]

because it simply doesnt check for it

iirc you can override the can crouch function on your character

so its not a bug, its just the default implementation

[dusky meadow]

Oh thats interesting strange they included it in blueprints without any options or warnings

[lofty rapids]

i'm trying to vinterp my camera actor to my player, basically this should take 10 seconds to get there, but it's just instead

i need to cache the value ?

it's supposed to be like a camera lag in theory

is it because i'm setting the location and this resets the current ?

[visual ember]

the actor location will be read first, then set, so no, it's not overriding in such way

[lofty rapids]

right so i thought i was using vinterp correctly

but it's not working

[visual ember]

any changes to location whatsoever?

[lofty rapids]

ya it's as if i just set them to the same

with no lag

[visual ember]

so it just snaps?

[lofty rapids]

correct

[visual ember]

tried lower speed?

[lofty rapids]

i think that was it i just had it to high

[lofty rapids]

thank you that worked

it's the simple things that can be a pain in the ass lol

https://streamable.com/tmp3lt

this is the effect i was going after

[faint pasture]

Why doesn't the DA include the stats as well?

[blissful grail]

Easier to work with in excel (DTs) and the hotpatcher so you don't have to deploy a new binary. You can just do a server update and the client doesn't need to download an update per say.

I used to put the stats in the DA as well until I learned about the hot patcher. Plus it does have the benefit of the one DT having all of the stats. So less jumping around when doing balancing changes.

[remote girder]

What is the better way of binding events to event dispatcher between actors? Like, now I'm using Level BP as middleman between event holders and callback holders, but I don't know if it's right thing to do with Level BP. My main logic for using it like that: Level BP already has all hard refs for all level objects, so why not use it as middleman and call it a day, lol.

[lofty rapids]

so your setting up bindings in the level bp ?

[remote girder]

yeap

[lofty rapids]

how are you calling them ?

[remote girder]

That's the problem too, because I need to listen for some trigger events to trigger events from Level BP, etc. etc.
Like, I kinda don't want to do coupling between objects, but level BP is kinda bloated with that

So, I want to find a better way of doing that, hehe

[lofty rapids]

well what are you trying to do ?

[blissful grail]

In BP? Your options are kind of meh.

Is there any particular reason you don't just have your callback holder have a reference to the actor that it is trying to listen to?

Instead of having the level BP be the middleman?

[remote girder]

I'm kinda afraid of hard refs (as far as I see, binding needs a hard ref), heh. And I kinda would like to avoid a hard ref coupling between actors.

[lofty rapids]

idk of anyway to call the function\events from another bp in the level bp, i don't know how to get the level brueprint to access that

[visual ember]

if you are looking for decoupling and a form of pub-sub solution, then check Dispatchito on Fab
it's my first plugin. free for personal use, so might just give it a try 🙂

[blissful grail]

Why? What is the actual thing you gain from it in this specific scenario?

[remote girder]

I suppose less unexpected things in the memory loaded with an actor, who listens to other actor and other actors listen to another ones, etc. etc.
Doesn't it work like that with hard refs? I'm kinda new to UE. Or I'm a bit paranoid with it?

[faint pasture]

the class is loaded, and in your scenario, it would be anyways

at least do a message bus on GameState or something, not LevelBP

[lofty rapids]

"You cannot directly reference or call functions inside a Level Blueprint from other Blueprints" <-- your kind of stuck with this situation

idk how to get a reference to the level

[faint pasture]

Honestly just totally forget that LevelBP exists

it's a trap

[lofty rapids]

the first tutorial i followed showed it as an example

but it's pretty useless tbh

[faint pasture]

All tutorials are shit.
They really aren't, but you won't know the difference until you don't need them.

[blissful grail]

1. The map already has both actors in memory. So the first point is moot.
2. You're being overly paranoid, yes.

Hard references are bad if you are using them incorrectly. As are most things in programming. A keypad hard referencing a door actor to unlock it is perfectly fine. And many games (even AAA) are still being released with this kind of thing happening.

If you really don't want to hard reference anything, BP is rough with it. But what you can do is build an actor component that acts as your message bus. Put it on your gamestate.

Inside this component you have a few approaches you can take. You can have the component have the event dispatchers that you care about. Then your actors that were triggering their own event dispatcher, can now instead trigger this. Then other things would just listen to it. This works fine for smaller games, but can get hairy as the game grows and the component ends up having like a bajillion event dispatchers. THAT DOESN'T MEAN YOU SHOULDN'T USE THIS APPROACH. Just build with this in mind.

Another approach would be to build some approach that allows you to create event "channels". So people would only listen for a specific channel. People typically build the channels with gameplay tags.

[remote girder]

Wow, thanks!

Yeah, I kinda feel like I'm a bit harsh on hard refs.
Will try to be a bit easy on it and just do what works and not very ugly to use/see. Also, maybe try with some GameState stuff, because I totally forgot they are exist, hehe.

[visual ember]

Shameless plug again:
My plugin Dispatchito is an event system based on a subsystem and using GameplayTag as topic/channel. So a centralized solution you can subscribe or send to from anywhere, without knowing "who's on the other side". Nothing crazy, but it's exactly what Duroxxigar described.
https://www.fab.com/listings/33543080-3d28-4ca1-911d-bfe8c0c37e21

[blissful grail]

People get caught up with trying to do everything perfectly. Don't. That doesn't mean to just outright do bad things. But situation dictates. As long as you understand the why on advices, that is what matters. Because then you can correctly articulate why the dang thing is either applicable or not.

[snow halo]

what is this?

[surreal peak]

Looks like something isn't properly loading anymore. Did you rename, move or delete anything recently? Might want to try cleaning up redirectors in all folders.

[snow halo]

thanks

This abruptly broke

I have no idea why. They used to be able to be connected

Now it all kind of broke down after I tried to use a data table variable instead of all these pins

I quickly regreted and realized Ive made a big mistake

my thought was: hey I already have all this data inside of a data table

[surreal peak]

I don't think this can connect, unless the cast node you are dragging off of is of the type you expect.

[snow halo]

and there's a difference sometimes between item names the player sees, and item names my unreal engine data tables and blueprint sees

difference in names caused problems

because in my crafting menu I couldn't hava spaces between words

and_they_all_had_to_be_like_this

with_an_underscore_inbetween_all_words

[surreal peak]

Whatever you use internally to identify your items shouldn't be player-facing.

You always want an FText to be player-facing, so they can be localized.

In theory it's also fine to grab the Class Defaults of the Item and do it that way.

[snow halo]

i mean its a soft class

[surreal peak]

Another alternative is to utilize DataAssets (that's what most peeps would probably do).

So the Blueprint would not hold the data, but the Data would be in the DataAsset, and the DataAsset would additionally have a class pointer to the Blueprint.

That way youc an work with the DataAsset everywhere.

And potentially also use UEs "Asset Manager" to return you all DataAssets of a given Class (e.g. items).

But that's besides the point. You have a generic Soft Class Reference there.

You can try changing that input to be a soft class of the actual item Blueprint

And see if using the "ToClass" on that turns it into the right classe.

[snow halo]

would that be more simple?

[surreal peak]

That said, I'm not sure if that node actually loads the Asset, which means you could just get a nullptr acception, aka accessed none, when trying to read the properties.

[surreal peak]

Wouldn't say simple.

[snow halo]

the problem is this...

[surreal peak]

Just different. fwiw.

[snow halo]

any time I have to make a new item

I would have to write the name of that item

in sooooo many places

[surreal peak]

Why

Even if you don't use DataAssets. If you put your Items into a single DataTable, you would have access to it via the DataTable.

[snow halo]

so this is my inventory data table

this is my crafting items data table

[surreal peak]

Sure, btw that first property "Torch" doesn't seem to be an FText.

I would change that rather earlier than later :D

[snow halo]

row names hav eto have underscores

[snow halo]

what do you mean?

it works

[surreal peak]

What property type is the "Name" property?

The one that has "Torch" written in ti

[snow halo]

wow

looks like I cant even open my item blueprints

wtf???

[surreal peak]

Are you using C++?

[snow halo]

no

blueprint

[surreal peak]

You must have moved, renamed or deleted something recently.

[snow halo]

its just unresolved errors

that I gotta fix

[surreal peak]

Based on your reaction I assume you did not set up #source-control before starting on your project.

[snow halo]

nope

I couldnt

used perforce

[surreal peak]

If you lose that project and all your hours spent on it, it's gonna haunt you.

Anyway, I still don't see why you need to write the Item name everywhere.

[snow halo]

the problem was, showcase of item, and item in computer language was different, thats what caused errors

[surreal peak]

Also the name property I'm asking about should be in the Struct that you use for that DataTable.

[snow halo]

what version control would you recommend?

[surreal peak]

For a single developer that potentially doesn't want to spent any money ,probably P4 on a free Azure Server.

[snow halo]

is it

[snow halo]

but my project is really big

like almost 30-40 GB

and I think im losing my project

[surreal peak]

That's pretty standard size fwiw.

[snow halo]

oh

[surreal peak]

Not having #source-control is a really bad idea. If you corrupt the project by any chance, you can restart. Only thing you can otherwise do is hope there is a backup of some of the files in the Saved folder.

[snow halo]

wouldn't getting a 50 euro hard drive disk with 2 terrabyte size be an easier idea?

[surreal peak]

But let's stick with the project for now.

• I still don't understand why you need to put the name of the item everywhere. If you set it up once in the Item DataTable, then you can always reference it via that DataTable by using a DataTableRowHandle variable.
• Can you please tell me the type of the "Name" property.

[surreal peak]

Well of course, but 99% of a time I tell someone to use Perforce, they tell me they can't afford 5€ per month.

So I stopped expecting someone to set up a small mini server with some diskspace locally.

If you can afford throwing a few terrybyte into an old PC that can run next to your main one, then that would be the simplest for now. You can installt the P4 Server on that.

That thing can still go down the drain, but at least you have one layer of proper backups.

[snow halo]

ive heard that version control doesnt save your whole project

only changes made in it

aka blueprints

etc.

[surreal peak]

That's half-true.

It does save a base-version of the file.

And then it saves further revisions to it.

How exactly this is done is more complex than one would think, cause there are a lot of things to consider when trying to store data efficiently.

[snow halo]

that would mean that it could go really easily up to 100 GB or more

what if you bring in a lot of models too

autosaves folder is like 10 GB right now

[surreal peak]

Assets are probably the biggest source of space, yes.

[snow halo]

and autosaves only keeps a few files saved everytime I make a change

[surreal peak]

But mostly everything else will barely take space.

I think after two 1-2 years of working on our internal project, we got to like 19.3GB on the Git Server (won't be much different on P4), vs the 5.12GB footprint of the project on my disk.

And this doesn't scale the same way, so 10GB project won't be 40GB on the Server. Only because you have 5GB more in the project doesn't mean it will produce another 15GB of revisions.

And that includes a bunch of source files. You should just make sure that you don't bombard your project with FAB/Marketplace assets that you upload but never use.

[surreal peak]

This message is still open btw.

[sand shore]

Of note, if you sync from source control at a specific CL, you DO get the entire project as-represented by that specific CL. It’s more like automatically saving thousands of versions of your project instead of manually saving a dozen versions.

And it scales much better than a full backup would

Anyone know why my stamina system isn't working? Basically, I made a stamina system that drains when i start sprinting, and when it fully drains, it stops sprinting and regenerates, this works as intended, however theres a weird issue where if i keep holding down the sprint key, it drains but also regens at the same time, allowing me to sprint endlessly, because it never actually fully drains.

[trim matrix]

hi, i have this camera bp that tracks the players movement but if the player walks into the trigger in a way thats rotated (like dosnt line up with the camera) the controls dont rotate to match along with the camera, in the clip im still pressing wasd in the same way each time after hitting the triggers but the controls i wasnt sure how to get them to follow along, rn i have it slightly working w locking camera input in the player bp when the player hits one of the camera triggers and that helped with another bug i had but this one is now left. just didnt know what i should do to fix this one

[faint pasture]

why the delays

[trim matrix]

wrong screenshot the first set iscameralocked should be true

[faint pasture]

You can do that much simpler.

Tick -> do any bools need changing? if so, change them -> update stamina and movement speed based on bools (select stamina regen or drain rate)

Input -> set a bool

The bools you'd have are bWantsToSprint and bIsSprinting

input sets if you WANT to sprint

on tick, if you want to sprint and you can sprint (stamina > 0), then you are sprinting

Stamina += Select(bIsSprinting, NegativeNumber, PositiveNumber) x DeltaSeconds
Speed = Select(bIsSprinting, BigNumber, SmallNumber)

[ancient dagger]

ok, i think i solved it, its working as intended now, thanks

[uneven crest]

I dont know why no AI Move function is working. The actor was spawned into the world. In the class setting I have a the AI controller set to spawned, and their is a nav mesh

[spark steppe]

your acceptance radius is very very very small

characters often have their origin in the middle of the skeletal mesh, so you would either subtract the capsule half height from your destination z value

or increase the acceptance radius

try with 200 radius, to check if it's that (because there could be other reasons, too)

@uneven crest

[uneven crest]

Ok thank you, I’ll try that in the morning. I’ve been losing my mind over it

Is AI move to the best option or a different one @spark steppe

[snow halo]

Hi im having a problem

This is the logic that I think is problematic

This old system was always working, but it abruptly stopped working recently, idk why 💔

The problem with it is that its always gonna break one item image

so right now the image that is breaking is "axe" image

but if I connect this data to the Item ID Row Name, then ALL of my images will break, not just one

And this Row Name thing needs to be fed some data

Ok this one seems to be almost a good fix for now, only one item didnt have its image load, which im going to inspect now 🔍

[frosty wadi]

[novel goblet]

Anyone done emission adjustments on decals with blueprints before? I can't seem to get it to work Temperature is the name of my scalar param

this is just a dummy test to see if I can make it brighter or not

[lofty rapids]

are you using the instance, or the original material ?

[novel goblet]

I Tried both, didn't have any luck.
I went and redid what I needed with just a material attached to a plane and it works fine so its something weird with Decals as far as I can tell. I tried doing Material Istiance -> Create dynamic -> set scalar _> set new decal material etc still no luck just couldnt' get it to adjust

works with the normal material just fine though

[sharp ferry]

the % of usage of my GPU while im working on the game is the same % of the final product?

because i have pretty lowpoly assets and not much

but % during the work is higher, probably is ray tracing or smth?

[sick sky]

editor consumes always more

depending on how you optimize your game this varies

[lofty rapids]

have you packaged yet ?

personally i just check the task manager in windows while the packaged game is running

this gives mea good estimate of how much it's taking up

[lofty rapids]

ya i would think this would work, and your sure the material has this parameter name that matches ?

[sharp ferry]

nope

[sharp ferry]

i have nvidia up telling me temp and all %

but it changes when u pack?

[lofty rapids]

well think about the overhead of the editor

[novel goblet]

yeah i double checked everything. Like I said I swapped it to being a material on a plane instead of a decal and it worked fine. So it must just be something weird with decals

[lofty rapids]

interesting, whatever works

[sharp ferry]

how do I enter in wireframe mode

[novel goblet]

yeah I'd like it to work with decals but for what I need right now its good enough

[sharp ferry]

yesterday i started to work on the accessories and products

[lofty rapids]

in the editor you can wireframe

thats also a good question for google

google is essential for stuff like this, try to google small things like this as people tend to help wiith things, but don't want to help with every little thing (usually imo)

[sharp ferry]

true yea

thanks

[lofty rapids]

did you solve this ?
https://streamable.com/nsqtud

[frosty heron]

I would entirely not use set view target with blend.

Imo if i were in your shoes i will make the camera movement logic from scratch.

[lofty rapids]

tbh i used a seperate camera actor and it works pretty well

[frosty heron]

Meh

Imo for the reference video, you just control the transition with timeline and curve

With some math

Take full control of the camera manager

Do the logic on update view (tick)

[lofty rapids]

i just interp the camera character to selected character position

keeping the rotation the same

but i think the curve idea is good for the jump

which i didnt include

[frosty heron]

Yeah you cant add custom behaviour like the jump with set view blend

It just interpolate all axis probably

[lofty rapids]

that was my first thought (svtwb), but interp with seperate camera is what i landed on that works

[frosty heron]

But you cant dictate the jump since it just interpolate from current view to target view

[lofty rapids]

either way you need a seperate camera

[lofty rapids]

^

[frosty heron]

Not how I will do it

Just one camera

All you need to know is where the position of the camera should be

[lofty rapids]

same, i'm saying seperate from the characters

[frosty heron]

The curve cant be applied to set view target with blend, so at the end of the day you cant get the result you want imo.

Going. From location a to location b with z offset shouldn't be a hard task

But then again camera is very tricky and not easy to solve

E.g when hitting the walls

Spring arm = shit camera

[lofty rapids]

how would you input someething into a timeline to curve from one to another ?

or woould you use the returned vector as like a offset ?

[icy mango]

hey, i need help. the objective system i've made works when i play in engine but doesn't after packaging (the text doesn't change) 😭 i tried adding delay and tweaking some settings, it still doesn't work

[frosty heron]

Timeline for z curve, rest is on tick.

You will have control with curve like ease in ease out, etc for the jump

Actually you dont need timeline

Just curve and tick

Variables you need is start time, end time. Starting location, end location and z offset.

Doodling with pen and paper is my best friend when thinking on what to do.

[icy mango]

@frosty heron can you guess what the problem might be

[frosty heron]

No but you can do some debugging

Try to break point or print string all the parts where they meant to be triggered

Then work your way forward

[icy mango]

yo i just checked again and got to know that if i turn on settings ui the objective ui doesn't work but if i don't it works properly

[lofty rapids]

https://www.youtube.com/watch?v=-a4To_QQoc8

@lofty rapids @frosty heron Just saw the messages. Thanks! looks very helpful. I'll definitely go through this later. Was very busy the past week so couldn't get around to this. My initial solutions did include set view with target blend and I did have issues since one solution incorporated delays because I wanted to possess the pawn after the blend was completed to not have a camera jump cut and the method @lofty rapids had that moved the camera back to starting position after possessing and then blending back to the possessed pawn.

After skimming the new replies, a custom camera is probably necessary. Can't wait to test these ideas out later today or tomorrow.

Thanks!

[lofty rapids]

my original solution was a bit hacky, i found it better to use a camera character, then just vinterp it's position to the selected character, much better and not so much a hack, also fairly simple

[lofty rapids]

this... and just switch the playerOne Reference

[wild pumice]

question on that. Since I will be using a camera actor now, once it reaches the new character, do I have to attach it to the spring arm of the pawn? I haven't messed with cameras too much but aren't there a bunch of springarm settings available in the components when you use the default third person camera.

[lofty rapids]

soo i made an empty character as my camera actor

which has a spring-arm and camera

it's just empty no character

and then i interp the location, to the selected character

so i'm actually possessing the camera actor

not the character

[wild pumice]

I see. Cool can't wait to test all this out.

[lofty rapids]

the way i set it up, you just set player one

so much better then view target with blend and trying to mash the alignment

[lofty rapids]

^and this and it's like magic lol

this only works btw if you have a parent class you can use

so hopefully you have a parent class that has all these characters as children

because switching the character on interp, you need to have the variable the parent class

so you can just set it to whatever is a child, else you need probably seperate paths and it'll be a mess

[sharp ferry]

it is a difficult thing to add audio to my scene?

like ambience room, walking?

[lofty rapids]

it can be as easy as the play sound node

there is also 3d sounds, and custom stuff

[lofty rapids]

for walking do you have a walking animation ?

i'm going to assume yes, and say you can trigger the sounds when you actually step

great for walking sounds

[zenith pond]

Do you think there's a faster way to voxelize an area based off collision with just blueprints? It's fast enough with the 20^3 volume, but becomes a crawl at anything much larger

[lofty rapids]

unfortunately blueprints is just not built for loops

make a BFL in c++, and offload this to c++ you'll see a significant difference

[zenith pond]

I figured, just thought it was a fun exercise and wanted to make sure I wasn't missing anything that might help

[lofty rapids]

https://www.youtube.com/watch?v=V707r4bkJOY

[zenith pond]

Like a better way to check collision or instance

[lofty rapids]

hmm i'm not sure what your doing in the pic, your doing a ton of loops ?

i cant really read the pic, it's not very high quality

[lofty rapids]

what are you trying to do create this sphere ?

[zenith pond]

Oh if you tell discord to open the image in a browser it should be readable

I want it to work with any geometry so I based it on collision checks

[lofty rapids]

what is it doing ?

your createing the sphere right ?

[zenith pond]

I just have a hidden sphere thats within the volume, but I want it to work for anything

[summer frost]

Is there any way to generate a custom error at blueprint compile time?

I have a subclass of Actor with a member TSubclassOf<MyThing> that can be edited in blueprints. I want to ensure that the user remembers to set this in any blueprint-derived class, and a blueprint compilation error seems like a great way to do that

[blissful grail]

I don't think so. Maybe using an asset validator.

That's the only thing that comes to mind for something like this.

Otherwise - C++ land.

[thin panther]

Or add a log into the message log, the standard practice for using unset references

[summer frost]

I'm fine working in C++, just don't know how to trigger C++ code after a blueprint compile

[blissful grail]

https://zomgmoz.tv/unreal/Testing/Validating-assets-with-IsDataValid

[summer frost]

IsDataValid() gets called as part of blueprint compilation and is exactly what I was looking for, thanks

Hey everyone, I’m trying to migrate the vehicles from the City Sample project by Epic into my own project, but I’m running into issues.
I migrated the "City Sample Vehicles" subproject separately, Works fine but its don’t include the destructible meshes .

Has anyone successfully migrated the City Sample vehicles with full functionality (e.g. destruction, physics)?
Is there a proper way to bring everything over, or am I missing some critical references from the main City Sample project?

Is there a way to get the Water Body Components to act like when using a Physics Volume and enabling Water Volume? Or do I have to put physics volumes everywhere my character can swim, ontop of the Water Bodies? The player's swimming only ever actually functions when using the Physics Volume, but when overlapping a Water Body it doesn't.

Hi I am reading some strings from a database and I need to breaklines at some of the variables. what is the correct "simbol" to do that?, I tried \n or {\n} with no luck. one solution is to find the \n in the input and conver it to shift+enter (see image) but I am wondering if there a more direct solution. or what the shift+enter character is? maybe I can save it directly to the data base without the need to convert it later.

[lofty rapids]

does this work ?

[proud notch]

apparently yes. but I am wondering if there is a better way.

[remote girder]

I kinda don't know which channel topic this problem is (if it's not appropriate to this channel, I will move it to UE4 channel): my custom player controller is SET inside my custom game mode (the setup is on pic 2) with all stuff, BUT input is not working and it spawns default camera (player BP has a camera inside btw) and for some reason it's NOT ENABLED on start no matter what I do (pic 1). Like it's been spawned, but just ignored or something like this.
Why it does that? I never touched it's lifecycle or enable/disable it anywhere, so I'm very confused why it does that. Maybe I mess up some settings somewhere, but I don't know even where it can cause it.

[lofty rapids]

the character is being spawned but not possessed ?

can you see the character in the world while your flying around ?

[lofty rapids]

do you have a player start ?

Hello!
Does anyone know if there's a way to save / load render targets to a save game object in Blueprint?

[steady night]

question

if i add "melee rank2" as a Unique bool an an array bool

will it just fill as a "bool variable" or as the specific bool

if i add melee rank 1 can the array tell them apart ?

not from the order they got added by ther identity*?

[dreamy marten]

In an array of bools, adding a "unique" element will either overwrite any "True" bool or any "False" bool. There is no way to specifically identify one bool (unless you give each bool a known index and only modify that index)

You may want to look at Maps if you wish to associate one unique identifier with one bool

[steady night]

hmm aye thanks

[frosty heron]

Whats the goal? Like saving a picture maybe?

[spark steppe]

an bool Array can only have 2 unique entries

true and false

[lofty rapids]

the don't have any identity really other then the index in the array

[faint pasture]

What are you trying to do here

What does this array represent?

[steady night]

yeah nothing really, i solved it i was just thinking loud.. (like ive never used an array before... lel)

[ivory vapor]

Hello everyone!

Maybe not directly blueprint related/feasible only with blueprints but I'm unsure where to post it to be honest.

I'm looking for a tutorial on making something like this https://youtu.be/SEk51GQdeag?feature=shared&t=455 (the landscape block building system. The video is already timed to start on it) or looking for an available ressource/plugin that already provides something similar ready to use. Would anyone know if such ressources exist somewhere?

Thanks and have a nice day!

[sudden briar]

I'm using GASP. I have made the camera first person. My problem is the turn in place is slow so the player is able to see into itself if they spin the camera quickly, anyone know of a fix for this?

[shrewd mural]

Is there a way to cut connections/links in a BP graph by interacting with the connection/link itself?

[zealous moth]

@shrewd mural alt + click?

[shrewd mural]

That does the trick, thank you!

[zealous moth]

@ivory vapor there were a few on the marketplace but apparently the landscape tool can do this if tweaked properly.

[ivory vapor]

I guess past tense means there is non currently up to date on fab? (I'm using 5.5)

Do you know any ressource on tweaking the landscape tool for this?

I have tried looking up for landscape block building system but only stull I found is how to make IN GAME block building like minecraft etc.

[zealous moth]

@ivory vapor last I checked there is a grid based one but otherwise there was another made public on git and there is this guy that is making a pokemon clone in unreal that made it work.
The problem with that last one is that he didn't code it in a friendly manner and you will need to reverse it to get it to work.
For the landscape, trial and error. It's not the most obvious.

[ivory vapor]

Would you have the names of those three? Whatever I look for doesn't seem to find them

[past jungle]

Hello!
Sorry for the delay. I allow the player to paint the landscape at runtime by applying brush strokes to a render target that controls a blend mask in the landscape material. So now I need to save / load the state of that render target whenever I save / load the world.

[frosty heron]

In this case, I am not sure then. Im assuming you probably have to serialize the data (r,g,b?) Arrays to the disk then load the array back when you need it.

Probably not a blueprint territory, but it's all assumption since I never try to do anything similar.

If what you need is to export the target data as texture, then theres already the function in blueprint.

[spark kestrel]

hey guys, just got into the server i have been running into an issue with my climbing mechanics in a 3rd person project. All of the mechanics for climbing seem to work fine except for whenever i approach the wall and call onto the climbing code it will teleport the actor back to the spawn location. Any ideas as to how to fix this?

[surreal peak]

You'd need to share your code. Otherwise quite impossible to know.

[spark kestrel]

im happy to do that what would be the easiest way for me to?

[surreal peak]

Screenshots of the parts of your graph that contain the logic you are talking about.
Or blueprintUE website, but I'm usually more in favor of the screenshots. Could do both fwiw.

[spark kestrel]

ok one moment ill get the screenshots

[spark kestrel]

i also get this in the Output log when the respawn happens

LogScript: Warning: Script Msg: A null object was passed as a world context object to UEngine::GetWorldFromContextObject().
LogScript: Warning: Script Msg called by: BP_ThirdPersonCharacter_C /Game/ThirdPerson/UEDPIE_0_Lvl_ThirdPerson.Lvl_ThirdPerson:PersistentLevel.BP_ThirdPersonCharacter_C_0

[surreal peak]

That MoveComponentTo node is sus

You aren't actually giving it a component

[spark kestrel]

in which line?

[surreal peak]

Ypu only have one of them or?

When you start climbing, at the end

Try to give that the capsule component and if that still doesn't work, try to set location and rotation of the character directly for now

[spark kestrel]

in all honestly i had been working on it for a while running into issues of it not registering the walls correctly so i looked up the issue and followed a video from like 2 years ago and it all worked great except the repawn happening so i wasnt sure what it was all about but i didnt want to break the code by trying to adjust it too much. This is my first full project so im still learning one step at a time.

[spark kestrel]

ill try this and see if it works

[surreal peak]

It's not respawning. You probably just have the spawnpoint close to 0,0,0 or stuff like that. You might also want to print the location you are passing into that node

[spark kestrel]

im using default spawn for now which i believe is 0,0,0. The Capsule Component into that MovementTo got rid of the warning in the output log but didnt stop the teleportation

[surreal peak]

Then try to set the Location and Rotation of the whole Actor directly and see if that helps.

If that still puts you to 0,0,0, then the location you are passing into that node is already wrong.
Start printing it across your code to see where it goes wrong if that's the case.

The MoveComponentTo can be replaced with a Timeline or similar, so it's not so crucial atm.

[spark kestrel]

i fixed the teleportation. i figured out one of my "get actor rotations" was plugged into where it was supposed to be "get actor location" so it was reading the rotation and translating it to the location where i was being sent

[surreal peak]

Ah yeah that wasn't visible on my phone. I see it now

[spark kestrel]

but now the issue im running into is after i changed that the rotation is no longer locked in place so as im climbing my character is "spinning" and clipping through the wall and effectively not reading the solid wall in the line trace so it drops the "climbing" structure.

[surreal peak]

I think it wasn't meant to be GetActorLocation

I think you wanted to use SETActorRotation

While you are using SETActorLocation.

The code looks like it was supposed to rotate you towards the wall normal.

That's the bad one

[spark kestrel]

well great after i "fixed" that i no longer teleported lol

[compact heath]

Good morning! I have a question about motion matching and manipulating it for top down controls. Am i in the right place for dialogue?

[robust belfry]

Idk why my quality options don't save just the text of combo box

AND OTHER

only volume save but idk how i've watched a tutorial for it and it's using savegame bp etc

[tawny hedge]

any recommandations for an advanced targeting system tutorial/course, has to include single/multi targets, lock on, skillshots ( projectile, trace, aoe )?

[past jungle]

Exporting as a texture could work as long as it could be imported again. I see nodes for exporting to texture, but they're editor only and I would need to be doing this at runtime as part of saving / loading the game.

I thought about serializing the rgba data. I don't know how smarter people than myself might do it, but that would be over 1 million pixel values to read / write in blueprint, even for just a 1k texture. Doesn't seem viable.

[frosty heron]

1 million pixels? I mean isn't a render target data is just one single static image.

[past jungle]

Yeah, 1024 x 1024 is 1,048,576 by my count.

[frosty heron]

I see but in any case it should be a cheap ass operation

if your computer can draw and update in real time, then your computer can easily store the bits.

[past jungle]

Couldn't hurt to try I suppose. I figured there was some kind of optimization wizardry being done that I don't know about.

[frosty heron]

I wouldn't try to optimize it yet, just try to serialize the bits and load it first.

it's a one time operation anyway. How bad saving a 1024x1024 can be.

formats

[lofty rapids]

is the only way to change to windowed mode using the console command ? there are no project settings ? i looked in windows section of preferences it doesn'tt have a setting

i mean in a packaged build

[frosty heron]

Have you checked GameSettings?

I can switch between fullscreen/windowed/borderless in package using that.

[lofty rapids]

where is this ?

[frosty heron]

right click on empty space in a blueprint and type game settings

should show you something

That's where you can change screen resolution, scalabilities, screen mode, etc.

[lofty rapids]

i got get game user settings, but no set

[frosty heron]

GameUserSettings -> Set Screenmode or something like that

should give you an enum option where you can pick between fullscreen, window mode and borderless.

[lofty rapids]

got it thanks,

i was looking for a straight set to windowed node, or a set game settings node, had to use get game user settings, then set node

[frosty heron]

you need to find the code that actually does that. With blueprint, it lives in the GameUserSettings.

can't pull a node out of thin air, it has to belong to some class, somewhere.

unless it's a static function I guess.

[lofty rapids]

makes sense

it would be nice if this was in it's own node though

set game settings, or set fullscreen mode

i mean you can always make a function to simplify this, but this would be convenient

[visual ember]

no, because you are not overriding the settings object

you get the object and act upon it

to set would mean to have second settings object and set it as a value

but not sure how consistent engine is with this approach 😛

[frosty heron]

Ehh, there's probably only one user setting object

I have my money the object is a singleton

Get Game User settings should return you the same object reference, where ever you call it.

you can test it with print string

No time to experiment my self.

[lofty rapids]

where would you put this for optimal switch time so thats it set and doesn't full screen then go back down at any point, the game instance runs first correct ?

[frosty heron]

Do you really want to force the player to always run on windowed mode?

[lofty rapids]

yes i do, untill there is settings i want to test it in packaged build and i want it to be windowed

so i can open multiples and test some stuff

[frosty heron]

Dunnoe if this is available in blueprint but I used GameInstance::Init to do stuff.

[lofty rapids]

it is available, thanks i'll try that (works great)

[lofty rapids]

how do you adjust timing in a packaged build ? as far as whats loaded and when ? i have a few ideas about it but the loading order is different in a packaged build ?

[visual ember]

I think standalone has the same order as packaged

There's also chart in here. Not sure if there is an updated version:
https://dev.epicgames.com/documentation/en-us/unreal-engine/game-flow-overview?application_version=4.27

[past jungle]

Turns out there's an export render target and import file as texture 2D node that are not flagged as editor only. I'll see if I can use those for my purposes. I haven't yet found a way to delete files in blueprint though, which I'll eventually need to prevent save game folders from filling up with unused textures.

[frosty heron]

There is, I pretty much save photos I take from the render target to a folder, then just load every image as texture when the game needs to load my picture library.

but that doesn't address the part where you convert texture to a render target.

this is not blueprint territory imo and you may get better help in #cpp

for what you are doing, I wouldn't even use texture.

just serialize the bits then load the bits when you need to restore the state.

I guess 1. Find a way to store the bits in format of your choice.
2. Find a way to load the bits back to a target render target

[past jungle]

I would prefer that, but the blueprint nodes exposed for render targets are weirdly limited. There are functions for reading pixel values, but not writing. There's even an operation for converting an entire render target into an array of structs made up or RGBA bytes, but no node as far as I can tell for writing to a render target using that same array of bytes.

As far as converting the texture to a render target, the "import file as texture 2D" node outputs a texture 2d, which I imagine I can use in a material parameter and then draw material to render target.

[frosty heron]

blueprints are made for designer not programmers

if you want to unlock the true potential of unreal then do what you have to do.

or live with the limitation

[past jungle]

I'll see if those export / import png nodes work for me. deleting unused files manually will be fine for prototyping purposes. Thanks very much for your help!

Hi I seem to be having a problem with a widget.

If a slot has an item, then clicking doesn't work.

The only way it works if when I double press fast.

But when a slot is completelly empty, then it works any way. Single press works only on empty black slots.

I dont want to double press fast on a transferable item slot to get it to move to the other side, that's kind of confusing, I would to have more consistency... Empty slots work with a single click

This is the slot im using

[sick sky]

seems like the item is blocking the hit

[snow halo]

true

but thats just an image though

[sick sky]

well image blocks hit i think

just open your item widget and see the visibilty value of all elements

[snow halo]

IMG_Icon is inside of this overlay

[sick sky]

by visibility i mean the visibility enum in the details panel

each UI elemnt has one

you need something like Visible & not hit testable

[snow halo]

I've set this overlay to non-hit testable and I've also just set it to all children

still same problem

[sick sky]

put this on all elements

to test out

(not on the slot)

[snow halo]

I've put it on all these selected ones

But this will cause an unexpected side effect which is not really wanted

which one specifically should I set to non hit testable?

which one is specifically causing the problem?

This is what will happen if I try to compile

its not letting me affect any change

[sick sky]

do you have some code runnong on construct ?

also, i usually have the item widget handle the clicks

and the slots doesnt

[snow halo]

oh yeah, I got this on pre-construct

its probably why its not changing

[maiden wadi]

Don't set it on every element. Set it on the root element and set it for not hit testable self and all children. So they everything else still functions as intended when this isn't blocking them.

[snow halo]

but this will mean, nothing will be clickable

[paper smelt]

Why am I able to move the object from side to side? I want to move it along a spline. It attaches and does move along the spline but the issue is When its following the spline it is still is able to move side to side if I move my hand side to side.

[maiden wadi]

I meant on the ones you don't want to be clickable. In this case your BRD_Border I think.

[snow halo]

do you mean to say that i should also be setting it via code to non hit testable

if row not found? etc.

[snow halo]

I fixed it

I actually had an override function - on mouse button down 🖱️ 🐭

the problem is that no slot has an itemID

but I also have a different kind of problem whigh might be related 🤔💡

I've made a duplicate of my slots

to distinguish character inventory slots from chest slots

so on begin play each itemID is going to have a unique name ID, im even setting in a variable at the end to save it 💾

but in the end when I go and make a click event 🖱️this itemID will no longer have data inside of it 🗃️📝

everything inside has been removed 🗑️

[snow halo]

This is kind of like a russian doll, each doll hides another inside, getting smaller and smaller. 📦 Box inside of box. 📦 Also a related fact about it is. Im passing the character reference like a baton here to validate it. 🏃‍♂️➡️🏃‍♀️ passed down like an Olympic torch of data 🔥... And so each thing will have the valid inventory_system_component actor reference which holds all the remove from inventory, add to inventory logic etc etc. But im not sure if this is going to be the right way to update the widget.. ⏲️ (But anyway thats another problem for me to handle later)

[chrome kelp]

Hey guys, is there a way to view return types of nodes in the material editor? In regular BP it's all color coded, but in the material BP graphs they are all white

[compact heath]

Okay im going crazy over here. I imported Motion Matching Animations to my project and I'm trying to manipulate it to be top down. Going for the "Seven the days long gone" vibe. The most trouble i'm having is getting my character to break idle root motion so as to turn in place when following the cursor. I've looked everywhere and I can't seem to find where the problem is.

Need help here #blueprint message

i will reply tommorow

[crisp moon]

so i have a widget it show that it is new.
after player clicks it in all instances it needs to disappear but i wasn't able to.
is there a way.

[midnight hound]

hi. i am working on timelines and need to fire specific event while middle of animation. how to check the track time and update animation in blueprint. tq

[last peak]

Just create a anim notify

[oak holly]

Hi guys, anyone know if there is a node like the Evaluate Curve node (in RigVM) in standard blueprints?

[last peak]

It would help if you explain what this node is supposed to do

[midnight hound]

need to do hide widget at specific time while animating between widgets.

[last peak]

So use a timer

[lusty birch]

yes, its got similiar name afaik

[midnight hound]

how to use?. im new to unreal plz explain

[lusty birch]

but curve asset needs to be external

[last peak]

https://www.youtube.com/watch?v=qc5WpNq7RFg

[oak holly]

I see, thanks @lusty birch , thats really helpful!

[lusty birch]

there are also nodes for curve table, so you can store all curves in one happy table

[midnight hound]

i can i use it in my case. i already have a timeline, just need to check the specific track point in timeline and fire an event. this is completely different i think

[sharp ferry]

Im planning to learn to make my character sit on a chair today. As first thing
Is it gonna be hard?

[blissful grail]

Not really

[sharp ferry]

So im gonna do now the animation first and with chatgpt that supports me i need to understand all nodes as well.

[sharp ferry]

For a total beginner in BP how difficult it is on a scale 1/10?

Total beginner in programming too

[blissful grail]

Don't worry about those things. They don't matter. Just work on doing it.

[sharp ferry]

I dont want to encounter tooo many nodes as first thing thats why, I need to undeestand them and connections

[blissful grail]

And you won't until you just start doing the work.

It is an easy enough goal. That I can assure you.

So go forth and be excellent

[sharp ferry]

Got it, im gonna try

Today i managed to add sounds, to the room, steps syncro and lights with chatgpt supports

[blissful grail]

Look at you. Already doing awesome. Just keep it up.

[keen atlas]

I do not get how these two values can even be None.. They are Widget of this blueprint

[maiden wadi]

Are you calling SetValues from OnInitialized?

[keen atlas]

No, but I believe I might as well be. I call it on the same frame as the Spawn I think..

[steady night]

hey im confused, im getting false on first branche if save game exists then i create a save game object then i cast from the load and it fails, what is the "load game form slot" getting the save from ?=

[next hollow]

Its gets it from the files.
Creating a save just creates the internal UE memory of it, you would need to "save to slot" to be able to then "load" it later.

[steady night]

ah'

so this basicly insteadf

[maiden wadi]

Make sure you call it after the widget has been added to a parent. The subwidgets aren't created until then which is why Construct or PreConstruct is usualy a better event to do init on than Init.

[next hollow]

Seems a bit redundent, but yeah.
It works

[steady night]

hmm still getting cast fail

[next hollow]

Check the savegame folder.
It may not allow the creation of a savegame that is blank/ 0 bytes of data.

Or, that string is blank.

[steady night]

yeah it was blank

my bad *

[sharp ferry]

im still trying to make my character interact With E key to the chair, it supposed until now to teleport on the chair because i added also a Hittarget on the chair. what am i doing wrong?

[steady night]

@next hollow how would i "clear" a save slot via blueprint ?

just "delete game in slot" ?

[maiden wadi]

You can just delete it.

[steady night]

ah ok

[midnight hound]

hi. i need to animate the widget inside another animation. it should have a fade in kind of effect. problem is i have a border in my widget and i am not able to render border using render opacity property. any idea?

[midnight hound]

thanks.

[faint pasture]

my guy just copy paste that save game object node, no need to have a waterfall of lines coming off it

it's all the same thing, just much easier to follow

[steady night]

ha yeah i know, im only doing some tests now x)

[sharp ferry]

can someone help me please

my character should be able to telport on the chair when im close with E

but its not

i dont even have errors below i dont get what is wrong

[faint pasture]

follow your execution line

[sharp ferry]

where is that?

[faint pasture]

the white

execution starts at your input event, and proceeds down the white lines

Nothing after GetAllActorsOfClass will happen, that's the end of it

[sharp ferry]

i dont understand, i have my Input that supposed to be E my first red node. i have the White line on pressed what should I move

[maiden wadi]

Look at the right of the GetAllActorsOfClass node.

[maiden wadi]

There's an unhooked white triangle.

[faint pasture]

white is the Do Things path

[sharp ferry]

print spring is triggerig nothing

when i get close

i see no hello

[faint pasture]

show your code as it is right now

if that bool is false then execution will stop at the branch

are you sure your input is even set up right? Have the input just print something

[sharp ferry]

turned bool true

and same

not works

yea

input is E

i sho wu

[faint pasture]

What class is this code in?

[sharp ferry]

BP_ my character

my main character

i made all the nodes inside there as i should

i also added the target and collision box to the chair

properly

[faint pasture]

Hook the input up to a print node, make sure the input is working

[maiden wadi]

Adriel (show your code) — 12:01 AM
show your code as it is right now

[sharp ferry]

the box colision is big enough

[faint pasture]

Let's see this again as it is right now

[sharp ferry]

yea it is

yes

[faint pasture]

show your code

[sharp ferry]

1 sec

doing

[faint pasture]

Does anything print at all?

[sharp ferry]

yes it prints Hello now

but as u said if i remove the first print the second is not

[faint pasture]

ok then either the bool is false, or there are no chairs to teleport to

[sharp ferry]

my bool is with the eye closed

[maiden wadi]

If it prints once, the bool is false.

[sharp ferry]

i turend also on the eye but same not working

i switched the eye to open and same

[faint pasture]

the eye doesn't matter

[maiden wadi]

Does it print once or twice?

[sharp ferry]

see

[sharp ferry]

i deleted the first print now

the second is not printing

the first was

[maiden wadi]

Cause the bool is false.

[sharp ferry]

i switched to true

is not working anyway

[maiden wadi]

Then something is setting it false.

There's nothing to stop that print besides that branch.

[faint pasture]

If the input works, either the bool is false, or there are no chairs

[maiden wadi]

Chairs don't matter.

That isnt' a for loop.

[sharp ferry]

i have the BP_chair

all setted there

[faint pasture]

Show where the bool gets set

[sharp ferry]

is B is vicino a sedia

[faint pasture]

show how that bool gets set true

[sharp ferry]

i thought was on true?

im cofnused

[faint pasture]

You probably have some code in your OnOverlap that set the bool, unless you want to be able to sit in the chair from across the room

show all code that changes that bool

[sharp ferry]

showint that part now

i think yea i did smth wrong here

[faint pasture]

look at the execution pins again

[sharp ferry]

are off?

[faint pasture]

they are not connected

[sharp ferry]

i forgot to connect the white exe ?

damn

[lofty rapids]

is therer anyway to set a delay when you close the window ?

[sharp ferry]

was this the issue?

ok now is triggering Hello

but is not teleporting on it

it should teleport on the chair

[lofty rapids]

like if someone closes the window, i want to play some animation or something before it actually closes

i need to be able to pause it for a second

while i execute something

[last peak]

Delay ?

[maiden wadi]

By window, do you mean widget?

Or like PIE?

[sharp ferry]

I also have a sittarget properly placed on the chair

[lofty rapids]

i want to pause the unloading, i created a multiplayer game and i'm using the browser widget with php as a server, i want to send a command to the browser on exit

i could just put a close connection button, but i was hoping to automate it

[maiden wadi]

If you want to dip into C++, you can override uhh...

[sharp ferry]

i don't understand why is not teleporting my Bp character to the HitTarget i've placed on the chair

can anybody help me to finish the task

[faint pasture]

Use breakpoints and prints, figure out where it stops working

[sharp ferry]

i cant connect anymore Prints from there

[last peak]

Ofc you can lol

[maiden wadi]

UWidget::RemoveFromParent()

UUserwidget(which I assume is what your browser is a child of) will inherit this from UWidget. You can override it as it's virtual and do your animation and then call the super of this post animation or whatever.

[last peak]

print the result of get all actors of class, print the sit target then print its world location

[sharp ferry]

like this ?

[last peak]

you should probably try it

[sharp ferry]

it downst allow me to connect a string to the GET node

[lofty rapids]

ok, i was hoping to keep it blueprints

[sharp ferry]

i tried

is not triggering Hello

[last peak]

And why do you think that is ?

[lofty rapids]

you have no execution

the white lines are important

[sharp ferry]

i dont know how to execute a string from the GET one

i see only blue nodes

[maiden wadi]

No luck there I don't think. If you just want a message send, that's easy, do it on Destruct, that runs when it's removed from parent. But if you want anything that should remove this widget to do an animation before and then remove it, you have to override that so that it won't remove it before the animation.

[sharp ferry]

two print strings on row

think i got it

print string to print string

[faint pasture]

my guy, where does the execution go after GetAllActorsOfClass?

[last peak]

Into the nether 😄

[sharp ferry]

connected

im blind

is not saying hello

oh no its working hello now

so from there thres no mistake

[last peak]

So now we know that your execution works untill you print hello for the first time#

Whats next?

[sharp ferry]

yes

the problem is the Hittarget

i connnected another one to the last node

to set actor location

a print to execu set actor location is not saying hello now when E

[last peak]

Why should it say hello`?

[sharp ferry]

should say hello if the logic is working

in this case is saying hello

but still my character is not teleporting to that hitarget

and i connected the last print to the last node nothing happening

says hello but my character not moving to that chair

[maiden wadi]

Show your currrent code again.

[sharp ferry]

it says hello

when press E near chair but still no teleport

[last peak]

Ok where are the other print strings ?

[sharp ferry]

i removed bc was fine since behind there

[last peak]

XD

[sharp ferry]

the problem is from Hitarget

we checked before it was fine

what am i doing wrong?

[last peak]

You are trying to debug, you have a bug in your code now you need to figure out whats wrong
To do that you need to print everything to pinpoint where the error is

First you print the reult of get all actors of class - get 0 - print string to see if it even exists, then you print sit target to see if that exists and finally you get world location and then you print that aswell to see what location its returning to you

[sharp ferry]

ok 1s. is ok

seems like last one is not

working

set actor location

like this? is not working

this supposed to be last print check

[last peak]

You need to connect something to your print string or else its useless

blue pin into pink hole of your print string

[sharp ferry]

to my pink print what should i insert there from which node?

done

there were

a node execution not connected

the get all actor of classs not connected to the last one

finally

now i will add the anim

thank u

still not clear how to connect a print in such a situation btw

[sharp ferry]

whast that .

dot node

[last peak]

it converts vector into string

[sharp ferry]

and what message it pops out like this?

[last peak]

Well read the nodes and tell me what you think

[sharp ferry]

it automatically generated the display name to me too

In string?

should says in string maybe

[last peak]

you get all actors of class
Then you get index 0 which means the first one you find
Then you get its display name convert it to string and then you print it
For the second print you get its world location which is a vector x 100 y 100 z 0 then it converts it into a string and prints it

[sharp ferry]

why would u get its world location

i dont underttand

understand why x2 string here

the final one

[last peak]

if you want to teleport your character you need to know its location

[sharp ferry]

yea the first string isnt enough?

its already to get all actors

[last peak]

The first print will show you the display name which is
Bp_Chair

But if it doesnt work for you you have to go step by step trough your code to find out where the issue is

[sharp ferry]

i managed to add the animation but now the problem is she's inside the chair and if i move the Hittarget, pressing wasd movs she not stay blocked on the chair

[snow halo]

i have a npc skeleton imported from fabcom for my ue and to that skeleton body BP i have a lot of seperated skeleton meshes inside of it as componets, so head is a different skeleton, arms etc, but that blueprint follows on every skeleton the same animations, im just wondering how to use it because that seems kinda complicated, also it has a delay on begin play 10 seconds and then simulated physics on all but some stay up and never touch the ground or they move kind of weird when they are being simulated, like the skull stays up 5 meters or 10 meters above the ground

they dont fully touch the ground but they do fall down and they do have physics

[faint pasture]

Isn't the whole point of a skeletal mesh that it's 1 thing with many bones?

[snow halo]

idk?

[faint pasture]

Yes it is

That should be 1 skm

[snow halo]

whats cool about it I guess is that the skeleton seperates

[faint pasture]

You can do that with a skeletal mesh anyway

[snow halo]

I wont be able to get it to seperate its bones if I have 1skm

[faint pasture]

yes you can

[snow halo]

how?

[faint pasture]

just do it? Bones can go anywhere

[snow halo]

I mean I would have to go to blender to unite all these bones right?

[faint pasture]

yes

or whatever made the thing

[snow halo]

but when how would I seperate them again?

[faint pasture]

vertices are weighted to bones which can do anything

[snow halo]

I didnt make it, like I said I got it from fab.com, its not mine, so I wouldnt make it like this, but the creator who made it seems to be officially backed by unreal as unreal sponsored their content for free some months ago and the creator seems to be having a lot of star reviews on their assets

[snow halo]

so i imagined maybe im just too dumb to understand it but people tell me no, it's the creator who made this who made it in a dumb way

[faint pasture]

https://youtu.be/t1-vhWNlTMI?si=C-UT4eMvgM7E20fX&t=9

[snow halo]

yes but that is still only one skeleton

[faint pasture]

Here's a skeletal mesh being blown apart

What's your goal for the seperation, what do you need separation for?

[snow halo]

I dont but it looks very cool

[faint pasture]

I mean what use case, for death effects etc?

or do you permanently need just a skull running around for a long time

[snow halo]

yeah I think that would look very cool

[faint pasture]

You can totally do that with a regular single skeletal mesh

[snow halo]

not running around but should have smart ai logic similar to my bear or my chicken

although more like the bear which is a hunter type animal that chases you to kill you

[snow halo]

not a victim prey animal but a big bad guy (predator) actor npc

and I barely made the other things work

using state trees which I found kind of easier than behavior trees

and that after I realized that coding all the ai logic into bp would be superrrrr complicated, I tried it and code got sooooo big and complicated and didnt work properly

and realized ok instead of ai logic inside of the actor bp itself i must have it inside of state trees

but I kinda hate state trees because they're so complicated too

and kinda hard to understand

i have very simply state tree logic at the moment

[faint pasture]

ok so what's any of this got to do with the model being 20 skeletal meshes in a trench coat

[snow halo]

nothing, just an interesting death effect 😅 😂

Im just wondering btw... how did you do this seperate meshes logic?

you said it was skeleton mesh?

if its static mesh compoentns then I know how to do that too i think

if I show you how cool the skeleton death effect looks you'll think you wanna keep it too.

[faint pasture]

just simulate physics on it

it's a ragdoll where the bones aren't constrained to each other

that's it

[sharp ferry]

i managed to do it and also block the wasd movts but hold the camera

i thought was more simple i need to re understand what i exactly used and did, but its done

[snow halo]

ok but check this out

[last peak]

Holy crap that are many skeletal meshes lmfao

Isnt that totally nuking your performance ?

[spark steppe]

the irony is that it could be one with many static meshes which use nanite 😄

i'll go back to struggling with the basics i guess... ||use a leader pose component!||

[snow halo]

nope

[snow halo]

why nanite?

I prefer to use LOD

nanine isn't really performative on small poly meshes like this one

I've been told by many professionals that nanite is even worse for performance if meshes are not very extremely high poly, like this skeleton, the components of it aren't that geometrically complex

edit: ok it's around 20 k per SKM component (it's kinda big in total)

i thought this would be much lower 💀

[maiden wadi]

I'd be curious to know their standpoints on this. Because my understanding of this is that this is false. Specially with virtual shadow maps which rely heavily on the nanite buffers to be quicker.

[last peak]

I thought thats common consens

If i enable nanite on a project with models that have up to 20k each i get a heavy performance drop

[snow halo]

20k isn't low complexity

[last peak]

Up to 20k is not something i would describe as high poly ...

[spark steppe]

that's all pretty irrelevant without context

[maiden wadi]

But have you profiled why? And what kind of scene are we talking about? The newer systems work together to perform better as a whole. They have a higher entry cost, but with any complex scene they'll be immensely lower cost than older systems without things like distance meshes popping in and whatnot.

[spark steppe]

you can't test nanite performance in a small scene, you must test it within a reasonable scene in your final game, and then everything possible should use nanite

[snow halo]

My thinking is, 20k by 20 SKMs

[last peak]

Well i looked up online why thats happening an pretty much every post i could find on the unreal forums and on reddit told me it comes at a insane upfront costs that only pays out if yo use super high poly models

Something like the city sample and that traditional lod's are almost always more performant by a lot

[spark steppe]

bullshit

[maiden wadi]

Super complex scenes. Not models. There are a lot of other considerations like massive drawcalls reductions and whatnot as well.

There is a higher entry cost. But it's more than worth paying for any game that isn't pong.

[last peak]

It seems to be the case for all my projects too, i have tried it a few times over the years and i never archieved higher perf with nanite enabled

Now to be fair my scenes were not ultra reallistic scenes with 1000000 triangles on screen

[maiden wadi]

Lol

1,000,000 triangles is nothing.

[spark steppe]

that's 2 1/2 skeletons for the other guy 😄

[maiden wadi]

Here, have a couple dozen trees. There goes your million triangle count.

[last peak]

What trees are you guys using?

if you use the nanite trees then sure .... mine have more like a few thousand

[maiden wadi]

That's like 300 trees or so. Now lets talk about the grass. And the rocks, and the mushrooms, and the characters, and the thousands of other meshes. It adds up quickly.

[faint pasture]

Nanite is basically a moderate base cost but kinda cheap/free scaling right?

[spark steppe]

i feel like dense non-organic areas also benefit because culling scales better

[faint pasture]

What about modular vehicles you think?

100+ meshes per player, plus the level

[last peak]

As i understand it at a certain point it can reduce performance costs drastically but that point is rather high

[spark steppe]

if you use lumen + vsm you are most likely always better with Nanite

[snow halo]

use a leader pose component!

I probably will not use that asset at all or I might use another one just for simplicity shake. But Im just curious for learning and knowledge sake, is ladder pose component a plugin?

i'll go back to struggling with the basics i guess...

Is there or has there ever been anything in Unreal or game development in the past that you "struggled" or "struggle" with that other people would find basic?

[spark steppe]

but after all, you got to test on your own in your project, in a reasonable scene

lucky enough it's not a big deal to switch between nanite and old LOD system

[last peak]

I would rather use Nanite and dont create Lod's if it would work reasonably for me 😄

[snow halo]

or use both ✅

[spark steppe]

use google, and don't search for "ladder pose component"...

unless you want ladders

[last peak]

I just never made it work

[faint pasture]

What's the approach to hard surface skelmeshes and nanite? You just have a skeleton and attach static mesh components or can it treat a skeleton with no weight blending as static and nanite it?

[spark steppe]

you have to attach them manually

i think since 5.5 there's also nanite for skeletal mesh support, but at least for me, there wasn't much performance difference yet, maybe it's better in 5.6 now 🤷

[snow halo]

I think you meant to say "Leader"

[spark steppe]

i said wrote that

[sharp ferry]

Tomorrow i will try to make her stand up always with E key

[blissful grail]

Higher upfront cost - wayyyyyyy better scalability than traditional methods

[maiden wadi]

Our current project has both set up. All meshes have LODs for non nanite uses and whatnot. RTS with topdown camera and some pretty highly detailed meshes and such. If I turn off nanite, my framerate drops by about 10-50% depending on zoom and content. It's never better without Nanite.

In fact, having it off also causes me a lot of heavy spikes from shadows. VSMs really hate non nanite meshes.

[blissful grail]

My games still perform better than if I had Nanite on. So it still depends on the project.

[limpid flicker]

can I see what ur game looks like? :3

[dull tiger]

Hello, does anyone know how I could create a setting in my settings menu to change audio output device during runtime? My game has VOIP and woudl like people to change their microphone

if anyones done this before, I'd be willing to pay for you to explain to me

[dreamy kindle]

Hi my weapon is backwards and no matter what I do in the actor rotation for my BP_Weapon it remains backwards.. any ideas thanks! https://cdn.discordapp.com/attachments/580659034546241537/1387991030384689283/image.png?ex=685f5ae1&is=685e0961&hm=69319356ec14cf4b2c9810cd3a0138ca1f89e5cebc78046ad99e1e367a7afc47&

zoom in of attachment of hands from the rep notify

[surreal peak]

@dreamy kindle One small note: Replicated Actor that get attached have Attachment usually already replicated by the Engine.

It could be that you are fighting that already existing replication path with your OnRep attachment.

Just something to keep in mind.

You are also attaching twice. It should be enough to only attach either the Actor or the RootComponent

And if you use SnapToTarget, you need to ensure the Socket is rotated correctly.

[dreamy kindle]

Ok I will try that and other things thanks 🙏

[dreamy kindle]

for now added a transform in code and it seems to work so far! weird issue..https://gyazo.com/c3027ab79170b925658dbbfaeffdfd7c

[surreal peak]

Can you show me the Socket on the Skeleton, especially its orientation (in 3D and the numbers), as well as the Weapon's MeshComponent (also 3D and the numbers)?

I feel like the Socket is just 180° off.

Or the bone it's attached to is rotated wrong in the 3D software already. Who knows.

[dreamy kindle]

whats weird is I tried rotating the socket inside the skeletal editor and it worked before as a non attached weapon item

only in code after attachment it seems to stick

[surreal peak]

Hm yeah, the problem will be easier to debug once you posted the additional info.

[dreamy kindle]

ok let me seek to do that, im still a bit new to BP but trying to learn thanks for replys

[dreamy kindle]

https://cdn.discordapp.com/attachments/580659034546241537/1388025983256494180/image.png?ex=685f7b6e&is=685e29ee&hm=aed50e29e1bd0b8d3d77a633c4c8630e5b4a9a8fd10b15e5e2a1ed2c9529f483&

[surreal peak]

How does it look like if you toggle that

And also show me the numbers in the details panel on the right please.

[dreamy kindle]

numbers for mesh

[surreal peak]

I just noticed I should have additional asked you to select the animation you are using when playing as a preview. My bad.

[dreamy kindle]

hm strange that the root is stretched

[surreal peak]

Can you select that specific Animation and take the 3D picture of the Socket twice more?
Once with Relative and once with World (the button I pointed at in the earlier picture)?

[surreal peak]

The bone to the back/right doesn't seem to be the root bone.

[dreamy kindle]

hm weird

[surreal peak]

The root bone should be where the 3D Gizmo is in that image.

[dreamy kindle]

I didnt make these anims but thats new to me its like that

yeah let me ask

[surreal peak]

All good, just trying to see where the rotation comes from

Can you please show me a screenshot of the actual Weapon Blueprint?

With the MeshComponent selected?

I want to see if it's additional rotated there.

So far, the Socket seems to already be wrong, as in UE the RED arrow is FORWARD (at least for now..).
Meaning the socket should be rotated 90° counter clockwise to point the red arrow to the "right" (right, based on that image).

But it depends a bit on the Weapon Blueprint.
