blueprint

[odd ember]

you dont want navmesh on your table

[proven river]

what if I want to be able to stand on the table?

[odd ember]

so you might want to look into your navmesh settings and cull areas smaller than x

are you an AI or do you move by mouse click?

[proven river]

VR teleport

so might as well be move by mouse

[odd ember]

I have no idea what that is

yeah but mouse click

as in, not mouse movement

[proven river]

yeah you click on a point and you teleport to it

[odd ember]

ah

[proven river]

if it projects to navmesh

[odd ember]

no

[sonic cipher]

I made it work perfectl thanks boss

[odd ember]

you dont need navmesh for that

[proven river]

ok it's weird the tutorial I was looking at was using one

[odd ember]

ah I see

yeah so if that's why you're wanting to project to navmesh then yes

correct

I had no idea that VR used navmesh for this but I suppose it does make sense

[proven river]

I didn't really either, I'm not entirely sure why

wait

I get it now, it's to make sure you don't teleport into walls

I had an entirely different system for that but I might as well have a navmesh if I'm going to be adding AI

[odd ember]

walls not so much but imagine you have spaces that are open that you dont want players to teleport to

you're in a forest and you don't want them to teleport over a hill etc.

[proven river]

yeah but wouldn't that apply to walls also? cause at the moment I can teleport into the surfaces of walls

which isn't really ideal

[odd ember]

sounds like your project to navpoint isn't working properly then

either that or your character capsule is too fat

[proven river]

I haven't tried it with the navmesh

I just meant like before the navmesh I could

[odd ember]

oh

[sand gazelle]

Wait, you're developing for VR?

[proven river]

adding that should fix it, hopefully

trying to, lol, but yeah

[sand gazelle]

Yo, same. Is it cool I add you? I'm ganna ask you some things later on

[proven river]

sure thing! just a warning I am developping in cpp, I just figured my navmesh question was better here, but they're pretty similar from what I can tell

[sand gazelle]

Haha ohh okay got it. Know anyone else developing on VR?

[odd ember]

you got a lot more space to operate in in cpp

[north bay]

Hi guys, anyone know how to get a reference of a game state of another player instead of my own?

[sand gazelle]

@odd ember would it be worth or waste to learn both cpp and blueprint?

[proven river]

it's still all the same stuff, just I type funny letters instead of using boxes

[odd ember]

what's your programming experience

[proven river]

I'm no expert but I'm pretty sure you can search by an actor name if that would help

[sand gazelle]

@odd ember very little C++

[odd ember]

ok but no understanding of architecture, hierarchies or principles?

[sand gazelle]

Oh yes, all of that

But not deeply

[odd ember]

how deep

dangling pointer?

generics?

[sand gazelle]

I know enough to make keyboard movement, and make a door that moves to the next level. (2D only)

[odd ember]

stick with blueprint

generally blueprint is the better choice because of the fast iteration time

[proven river]

plus when you do cpp you need to recompile like all the time it gets a little tedious

[odd ember]

but cpp has more depth and can be a preference later on

[sand gazelle]

@odd ember got it. I'm following unreal engine's learning path for VR developement and I understand very little about the code they just made me make. That normal?

[odd ember]

yea hot reload is sadly garbo

[sand gazelle]

@proven river oooh

The instructor isnt explaining as much of what these things are

[odd ember]

I mean if your code experience is literally "hey do this thing we tell you to do" then yes, it is normal

[proven river]

I tried that path and that's kind of why I stopped using it, they also just said "yeah use the default movement stuff" even though I had no idea what it means

[odd ember]

I wouldn't even do VR in that case

it really is its own can of worms

[proven river]

well I understand it all now, smh

I almost have full movement

almost

[odd ember]

that's just the first basic hurdle though

[sand gazelle]

😂😭

[odd ember]

not to demotivate you or anything

[sand gazelle]

Well in my case, I bought my pc For Vr developement

[odd ember]

just saying you'd get a lot more understanding from making a 3d project than from a VR project

I can't imagine you'll be shipping these games if both of you are doing this for the first time

[sand gazelle]

Oh I went through a level design class already with 3d

[odd ember]

a LD class... for VR? for 2D? 3D?

[sand gazelle]

I'm at this point and don't understand anything

[sand gazelle]

Oh level design for 3D Not VR

[odd ember]

not sure who'd be teaching those

[proven river]

hey I'll explain what I can if you need help understanding

[odd ember]

nobody knows how to do much VR LD yet, and even those that do certainly wouldn't be teachers lol

[sand gazelle]

Oh no no bot VR level design

I meant I had a college class called Unreal Engine Level Design

@proven river and omg plzzzz

[odd ember]

I see

[proven river]

impressive you have a college course for that, I'm just reading forum posts and hoping

[dawn gazelle]

Only one game state exists, and in multiplayer it exists on the server and replicated to clients.

[sand gazelle]

@proven river surprisingly in Kansas

[proven river]

I'm also in Kansas I just didn't look for game development schools because I'm a normie

[sand gazelle]

Daaangg

JCCC is where I was taught. But yes that darn code, you can explain in a DM if you can so while I'm working i can read when I can

[proven river]

JCCC is fantastic, especially for the price, I'm currently going to KU but I took some classes at JCCC to save money

[sand gazelle]

That's smart

[north bay]

@dawn gazelle What I'm trying to do is to get the coin amount information from the other player from the PlayerState (That should be possible right? 😛 ), Now I'm only able to get my own information from the PlayerState but not from another player.

[dawn gazelle]

How are you referencing your score that is correct?

[north bay]

I made a bind on the text,

This is the Coin Blueprint btw

and in the player controller this event is called

[quiet token]

@maiden wadi r u there?

[north bay]

Pherhaps I need to pass it in a way to the gamemode first?

[quiet token]

Mhh, someone else can help me maybe? Now i know the Problem better, but we still didnt found a solution and this is the last step before i can move on to the map design: When my player jumps forward and in air presses "left", he should add force to "forward + left". This must be easy, but i'm too noobish and stupid i guess

need this for strafe jump

and ofc he can do this to the right aswell. i can add the force, but its never relative to the players current direction

this is how the movement works right now

[lime fulcrum]

Hi!
Is there a way to round numbers to have less decimal points (float)

[maiden wadi]

@quiet token Here. If I understood correctly, you want to jump, and add movement input to the left of where the player is moving towards regardless or camera direction, or do you want that left movement to be in regards to camera facing.

[lime fulcrum]

instead of getting 0.002345 or 1.00452, to get like 0 and 1

[odd ember]

floor?

sorry

[lime fulcrum]

lol

[odd ember]

floor?

[lime fulcrum]

but I want it to be 0.02 precision, and not 0.023489507390549826

or whatever

or should I floor but then multiply by 10 or 100

🤔

[dawn gazelle]

I made this nifty function yesterday that might help.https://blueprintue.com/blueprint/xz_0sp44/

[lime fulcrum]

😮

[odd ember]

I want to love it

but I can't help but think it would be better converted to cpp

[dawn gazelle]

Probably XD

[lime fulcrum]

what does it do? 😮

[odd ember]

also tbh you could have gone for ultimate insanity and made it one long nested select string

[dawn gazelle]

Take an input, and it'll round it to the nearest decimal or value of your choosing. So input of 99, nearest 10, will round to 100. Input of 99.35, nearest .25 will round down to 99.25

[lime fulcrum]

Wow

[blissful lava]

Why can't you just multiply by 100, truncate, then divide by 100?

[lime fulcrum]

I was about to do so

[unique falcon]

just want to give a shout out to @atomic salmon for helping me solve a bunch of quite hard but cool issues with some stuff he posted way back in november 👏🏻 👏🏻 👏🏻 👏🏻

[dull tree]

I need help with that

is there any faster way to do it?

u made MainGhost and then child of them like here

[lime fulcrum]

What are you trying to do exactly?

[dull tree]

but when i am useing get actor fo class and then check Mainghost it only counts one

i have this

and only one child (ghost) have this boolean on true

i dont know why

i can send more ss if this will make this more clear

[lime fulcrum]

explain what are you really trying to do? Communicate with many blueprints at the same time?

[dull tree]

i thinks so

[orchid garden]

knowing the inaccuracy with floats did you try that to see if it works for getting the nearest floating point value? (0.35 etc)

[dull tree]

i think u made bad choice

i did 4 blueprint chillds for 4 Ghosts (to change colors :P)

[dawn gazelle]

It'll only work so well as the engine will let it.

[lime fulcrum]

You should use an interface and do a "Get all actors of class (Just the parent class) and send the message in a loop of such array

[maiden wadi]

@dawn gazelle @odd ember @lime fulcrum

[lime fulcrum]

😮 oh

[dawn gazelle]

XD

[dull tree]

can u help more 😛

im bigginer

[dawn gazelle]

does that work with negative values too Authaer?

[dull tree]

or any links to how to do it

[lime fulcrum]

Do you know how to use interfaces?

[dull tree]

i know to blue print but dont clearly know how they work

[worthy frost]

i recommend checking out the Blueprint Communications tutorial

before going any further

[odd ember]

a swiss army knife

[lime fulcrum]

Exactly

[dull tree]

ok 😄

[maiden wadi]

Actually I did realize an issue, it doesn't work perfectly with negatives, I'm fixing that really quick.

[twilit heath]

also wouldn't hurt checking a tutorial on inheritance @dull tree

[lime fulcrum]

Oh

[dull tree]

ok 🙂

[worthy frost]

also btw, you can use just one BP for all ghost colours

and have a enum that describes the colour

i would only create children if they have vastly different logic

[odd ember]

for a second I thought the concept of ghost colors was universal

[dull tree]

i didnt know how to change material so

but thank u for help 😄

[worthy frost]

well your material would have a vector param you override

for the color

you create it dynamic, and adjust that param based on the color you want the ghost

[atomic salmon]

Thanks, glad it helped! 😄

[dull tree]

good to know

[lime fulcrum]

Anyone have a formula to calculate the external speed of a "wheel" based on angular velocity?

calculate the most external extreme

[atomic salmon]

V = omega * R

[lime fulcrum]

was it something like ANgular Velocity * Radius ?

how do I get omega?

[atomic salmon]

Not something like, it’s exactly that

[lime fulcrum]

LOL

[atomic salmon]

Omega is the angular velocity

[lime fulcrum]

oh ok xD

Sorry

[atomic salmon]

In physics everything has a letter for it

Either Roman or Greek

[lime fulcrum]

yah, I haver studied that stuff. which I regret a bit

so, thanks 😄

[atomic salmon]

For more physics come to the #legacy-physics channel 😉

You are welcome

[lime fulcrum]

oh, right 😄

[maiden wadi]

@dawn gazelle @lime fulcrum Best I could do with the negative value fix.

[lime fulcrum]

Thanks again 😄

[maiden wadi]

Insane though, how hard it is to work with math in blueprint compared to C++. :/

[dawn gazelle]

That's definitely neater than mine. Well done 😄

[atomic salmon]

You can use a math formula node

[maiden wadi]

Could get rid of the boolean too.

[atomic salmon]

Makes it much more fun

[maiden wadi]

And that is also true, I keep forgetting those things exist.

[coarse marten]

i feel like this might be a C++ only thing but is there anyway to prep a level up? Kinda like level streaming, and might actually be level streaming but i'll explain real quick

Hypothetical fighting game with a menu loop that has..
a Title Screen,
a Stage select, and a character select, you pick your characters and you jump into the game with the stage you picked

Is there anyway i can tell UE4 for example to load the stage while the players are selecting their characters if it's already been determined where they're going to go?

[maiden wadi]

That would have to use level streaming. Any other map loading will destroy the current level, which is also where the players would be choosing their characters.

[coarse marten]

that leads to my second question then

how would i change the gamemode with level streaming?

because the main reason why i havent really tried to test it with level streaming is because... wouldnt the game mode have to be the same? Like if i had a menu game mode that was handling that the character select and i told it stream in, i wouldnt know how to tell to change game mode. If that makes sense.

I mean i could just load level and let its do its thing in the world override but, the thought only popped up in my head when I was modding SFV

i was doing a uni level design piece and thought it would be cool to mod into SFV, its a bit finnicky on certain things so i would get a game crash, but the game would crash as soon as it started loading the level, which was as soon as you selected it in the stage select

so it got me wondering "huh wonder if you could set something up like that with level streaming or something else"

[odd ember]

technically every level should be equipped to be handled by its own game mode

you'd have to handle the switching of game modes in the game instance, most likely

[coarse marten]

Wait you can SWITCH IN THE GAME INSTANCE?

there's too much stuff in this engine my lord

[maiden wadi]

@coarse marten It's possibly worth noting that level streaming is likely overkill for a fighting game. Normal map loading should be more than sufficient and very fast.

[coarse marten]

all the main fighters level stream in their maps in pieces from what i've messed with

Soulcalibur VI, Tekken 7 and Street Fighter V all stream in their levels from different map files, i just noticed that SFV did it in the character select

[odd ember]

SF has to do it since it uses live character models for its roster screen

[coarse marten]

Ah yeah i meant for the maps in general, especially for the Namco games

but tbf it looks like they're chunked for organisation reasons?

e.g

[odd ember]

it's pretty standard practice to use one map per role/discipline so you can work on it without impeding others

[coarse marten]

Oh yeah that's true!

[odd ember]

assembled all with the persistant map

which will function as a map manager of sorts

[coarse marten]

VI seems to have like.. Map data aswell in another file, which is.. not in the screenshot i took lmao

but that seems to handle proprietary stuff they made back in the PS3 days they're still using now along with over things. It's all really cool stuff i enjoy looking at 😄

[odd ember]

it does give insight into how stuff is made in larger teams

but this is universal

[coarse marten]

I appreciate all the help here though! Got some ideas im going to play around with now 😄

[odd ember]

#graphics @trim matrix

[trim matrix]

Oh whoops my bad 😆

[elfin girder]

Someone help me with Rotator math? I've made a teleporter, but I want the player to keep their control rotation on the Z axis relative to the teleporter after moving locations. Here's an illustration I made:

[coarse forge]

so.................................... is there a way to have a material dynamic instance in a blueprint? And..... If i wanted to make a weather system.. I can add the cloud volumes, directional light, sky atmosphere etc to one bp?

[odd ember]

you'd be better off with a subsystem than a blueprint I reckon. or a material attribute collection

or whatever they're called

but yes you can have a dynamic material instance in BP

[coarse forge]

hmm

Can you drop a BP that has those actors in it?

or.. do you have to place them and then manipulate them via the bp

or subsystem?

im familier with the subsystems

[odd ember]

you... have to place them, or give the subsystem room to place them

[coarse forge]

just nothing that would group all these things into one

[odd ember]

tbh there isn't a good way to centralize this

perhaps for good reason

[coarse forge]

lol

k

it would be tooo easy

to be like.. here are your 4 actors.. and.. here is a bp that changes all these things to make storms and day/night

hahah

[odd ember]

material parameter collection I reckon they're called

perhaps that is of some use

at least for the material part

for the remainder, lights etc.

you can always create an actor that has a skylight etc. inside of it

but you'll still have to select each component individually

[coarse forge]

I guess.. i could try the level bp

[odd ember]

normally I'd say yes... but what did you have in mind to do there?

[coarse forge]

let me give you a screen shot

one second

dont worry i made it in paint

so this is my title screen im working on

[odd ember]

... so you want all of this

[coarse forge]

and the clouds move, etc and the water moves.. etc

[odd ember]

just for a title screen?

I mean I don't think overkill even begins to describe it

[coarse forge]

but i'd like to have the sun rotate and potentially change the clouds like lighten them and show a starmap

for the night cycle

well............

ill use the same stuff for the real game level

title screen is key man!

😉

dont' worry.. i thumbed out the piano for the bg music for it today too

😐

[odd ember]

it's like you'll be setting people up for disappointment

[coarse forge]

so I mean.. the idea is.. a weather system.. that I could drop into any level

hahahah.

[odd ember]

best title screen, but no game mechanics

one of the features I'm planning for is a storm system

[odd ember]

not so much a weather system

[coarse forge]

i mean.. there are game mechanics

im at the part where I'm starting to tie things together

[odd ember]

but I'm planning to use (yet another) subsystem

[coarse forge]

hehehe

can you do a subsystem bp?

[odd ember]

nope

[coarse forge]

well oopse

hahahha

[odd ember]

but they are exposed to bp

[coarse forge]

sure

hmm.. but then.. i guess you'd use delegates to send changes to the stuff

or........!!!! is all that in the world

[odd ember]

anyway I think you'll have to figure out what the parameters of the weather system you want is

[coarse forge]

the light, etc

[odd ember]

like how is the weather created

etc.

[coarse forge]

yeah I have that

[odd ember]

is it a die roll?

[coarse forge]

make clouds thick.. add rain.. add wind.. make the water crest more

its already sorta there

[odd ember]

oh

[coarse forge]

but.. i think it should also sorta control my day/night cycle

since I need to adjust clouds etc during those times too

[odd ember]

I mean try looking for a tutorial

[coarse forge]

i did

[odd ember]

you seem to want a lot more from yours than I need from mine

[coarse forge]

lots of 2014 stuff that wasn't it

🙂

well i guess the day/night stuff can be sep from the weather system

ill start with the day night

thats pretty easy

i think

tick.... rotate directional light

[odd ember]

statistically you'd be wrong

[coarse forge]

hahahha

5/4 kids are bad at fractions

[odd ember]

but yeah I think rotating your direction light might be it

[coarse forge]

for day night yeah

[odd ember]

now you'll have to figure out the conversion rate between how long a day or night is in game compared to real life

[coarse forge]

okay.. let me spin a bp up and see if it can access the directional light from there

[odd ember]

you can do it in level BP

[coarse forge]

i feel like Authaer is going to make my day.. hes typing a lot

[maiden wadi]

If you want a self contained system, why not just do it all in the same class that you can drop into level?

[coarse forge]

^

thats where I started...

[odd ember]

I mean sure if the components are there go for it

I just don't think everything is exposed

[coarse forge]

my q is.. can you put directional light.. height fog.. sky atomosphere skylight and volume clouds in one class

I think.. they are all actors...

[maiden wadi]

Skysphere is just a mesh and a material, Sun is a directional light.

[odd ember]

is directional available in BP as a component? I forget

[coarse forge]

alright.. ill start there

to cpp I go!

thx

[coarse forge]

magic leap is what i was hoping for

[odd ember]

I still wonder if anyone's using that

[maiden wadi]

I don't even know what magic leap is.

[odd ember]

or why it is enabled by default

it's a company

that managed to lay off quite a bit of staff pre corona as well

yet made it into the default package of unreal

some sort of ar device

or vr

anyway directional light and meshes, you can handle materials for clouds etc. dynamically

[coarse forge]

yeah i have the mat already

[odd ember]

you could also attempt to implement the logic for how you want different weather to appear

[coarse forge]

sure

[odd ember]

you can just make it random

[coarse forge]

yup

[odd ember]

but I imagine you'd want each weather type to have a duration

[coarse forge]

well after its working ofcourse

[odd ember]

and a start/end phase

I think the long dark does it well in this regard

[coarse forge]

right now i want to focus on day/night

so I'll start there

well packaging those 5 things under lighting

since that will exist on every level

the water settings wont

[odd ember]

well the water isn't part of the weather

unless you want to count cases like tsunamis, but those would have to be separate meshes anyway

[maiden wadi]

Hmm. I need to do a day/night system as well. I'm also going to need to tie it into my foliage replication system, which I need to work on a bit more.

[odd ember]

oof that sounds complex

[maiden wadi]

Funny enough, the foliage replication was very easy. I subclassed the foliage HISM component and used that for painting. Easy level design. Then made a second class as a manager that is the replicated one. That manager gets all of the subclassed foliage components, and I simply add to a replicated array, that is an array of a struct which is the component's mesh type, a compressed location and compressed yaw for rotation. It replicates that, and each client just removes that mesh instance at that location until that array entry is removed. And I get to keep the HISM draw call performance with harvestable replicated foliage.

[coarse forge]

nice

[odd ember]

not sure where level design factors into that but yeah

probably not that difficult to tie into a day night cycle

unless you count weather in that too

[maiden wadi]

You can use the foliage painter to simply paint new foliage into the map. So the level designers job doesn't change at all except to simply select a different thing from a dropgdown menu.

[coarse forge]

things ill have to deal with later

[odd ember]

ah like that

[coarse forge]

most likely when I add wind...

[maiden wadi]

FoliageInstanceStaticMeshComponent is the default one. Just adding it to the list of meshes, and changing that mesh's component to the CInteractableFoliageComponent allows the foliage to be interacted with.

[odd ember]

I don't think I'll do day/night simply because the increased workload that I have to consider for e.g. lighting a level twice

the storm system will be fun though as its seeding will be based on the actions of actors and the player in the level

[coarse forge]

@odd ember are you on 4.26?

[odd ember]

no

[coarse forge]

ah

its neeto

[odd ember]

not switching until it's stable

[coarse forge]

lol

well... im using it

you literlly.. just rotate the directional light

[maiden wadi]

I want to use 4.26, but that interface bug kills me. :/

[coarse forge]

😐

oh with the bp

[odd ember]

I mean it's not about the directional light rotation

[coarse forge]

yeah

[odd ember]

it's that during night time you have to consider different lighting

and ideally you'd want your gameworld to respond to the fact that it is night

[coarse forge]

sure.. emmisive control

on your clouds

[odd ember]

so essentially you're creating 2 or 3 or 4 levels per time of day, depending on your granularity

[coarse forge]

and try a soft wide light for stars or moon

[odd ember]

that's only one your directional light

[coarse forge]

ill let you know how it turns out

[odd ember]

what about manmade lights etc.?

[coarse forge]

i mean.. turn em on

[odd ember]

that's a big point to consider

[coarse forge]

im in like 3000-5000bc mesopotamia

[odd ember]

fair

[coarse forge]

not super woried about nightlights

[odd ember]

so for you it's probably a bit easier

[coarse forge]

one does hope

[odd ember]

that kind of stuff is exactly what I'm talking about

I usually wait for .1 or .2 hotfixes to come in before switching

[maiden wadi]

I feel sorry for people who have a lot of engine changes, that upgrade. That's brutal.

[coarse forge]

eh.. i was on 4.24 making water.. then ran into a problem trying to merge splines and planes

so i started upgrading then

to use the new water system

yeah.. i am going to try as much as possible to not do engine changes

[odd ember]

yeah I don't do engine changes. if I would I'd separate them out in a module that is my own

[night wolf]

Hey so I have a simple ai that follows my character, and it is given authority by the default navmesh bounds volume, and it works fine when I play it in its own level in the editor, but when I start by opening a menu level, and then the level that actually has the ai (from a button on the main menu) the ai no longer chases the character, I’m wondering why? I think I’m in 4.24 btw (sry for long message)

[odd ember]

are you spawning the AI or is it in level?

[coarse forge]

double check the navmesh bounds volume

4.24 gave me random fits where I had to move it up 1 then back down 1 sometimes

there.. is a button to make it show green

so you know its active

[odd ember]

I managed to skip 4.24 entirely

[coarse forge]

O.O

[night wolf]

It’s just in the level

[maiden wadi]

P in the editor will show you the navmesh.

[odd ember]

but had my share of issues in an old project on 4.23 that instantly got resolved jumping to 4.25

[night wolf]

Alright

[maiden wadi]

I think 4.24 was my first version. I started right about the time it was released.

[coarse forge]

i started in March of last year

[night wolf]

Last time I checked the green thing popped up in the right places when I pressed p

[coarse forge]

not sure if 4.25 was out yet

double check the center of the actor.. make sure it isn't in like the ground some when spawned

my pigs had that issue too

[night wolf]

I was wondering if maybe anyone thought making an entire ai logic and blackboard or something like that

Or if it’s another issue

[maiden wadi]

Check the character reference from the AI first, make sure it's still getting the reference fine.

[night wolf]

Alright thanks

[odd ember]

@night wolf you can also use the SHOW navigation command in console

[night wolf]

Ooo I haven’t tried that yet

Thks all 👍

[maiden wadi]

@night wolf I find that most things that break when you move from PIE to loading into one level and then another, is often race conditions. How are you telling the AI to follow the character?

[night wolf]

Yes

Oh wait whoops

Read it wrong

It’s just “on see (pawnsensing) move to and then it is attached to my character (third personcharacter)

Not sure if there is more (I’m not at my pc right now ) but I’ve been over it a couple of times and I think that’s it

[maiden wadi]

Hmm. Might not be that then. 🤷‍♂️

[odd ember]

I'm thinking you're right with the race condition

and it might be that it's somehow not coupled to the AI controller correctly

[dusk basin]

I have a multiplayer question when a player joins my multiplayer menu I want a player to spawn on player login and despawn on logout only issue is the event on player login is counting me the host as a player therefor spawning a player when I don’t want it to be spawned is there anyway to exclude the main host of the server from triggering this event

[trim matrix]

I want to cast to third person character, but I used up the thingy before, how do I make more room?

[dawn gazelle]

just drag another wire off of it?

[trim matrix]

off what? the set speed? because that'll just add to the connection

it won't make a new one

damn- anyone here?

[dawn gazelle]

you've already casted to third person character in your screenshot. You can drag more wires from the reference on that cast node. "Thingy before" is not very descriptive, and "make more room" doesn't make a lot of sense in this context.

[trim matrix]

ohhhh okay

thanks

[rugged wigeon]

@dusk basin Switch has authority sorry ignore that. Do a check on the player controller. The listen server will be player 0.

[edgy halo]

Hey how can I store the value I take as input in the umg and transfer it to the next variable?

[rugged wigeon]

in the event graph of the UMG widget, create a variable, and set it to the current value of the umg input

[atomic prairie]

hey, I've created a widget which is linked to my interaction object to display the button or key to use, but this one follows my character, is it possible to make him follow the camera rather than the character?

here is my BP, but I can't find a similar one to GetActorLocation for the camera

Ohhhhh find!!

[quiet token]

Hey! I have a vector variable with an offset wich is always at the same place relative to the character. When i jump i want to add force into that direction. The force part is working, but its not relative to the players position. maybe u can help?

all happening in fps character bp

[tight schooner]

Get actor forward vector?

[quiet token]

ah i only have forward vector

ure right

dude i'm so dumb

good to know, but its still not workin, doenst make me feel better hahaha xD

[tight schooner]

Well, I'm not sure what your BP script is trying to do

[quiet token]

i'm tryin stuff

cuz no one can help me with strafejump here

so i want to add a force to that relative point infront of my char

[tight schooner]

Are you trying to make the "left offset" relative to the player?

[quiet token]

yes

it is

when i rotate player it moves with him

[tight schooner]

Rotate vector node... Rotate the left offset with the actor rotation

Or you can get actor right vector

[quiet token]

mom

i try to understand, im pretty new

back in one min

[tight schooner]

(and use Negate Vector to turn the right vector into left vector)

[quiet token]

i dont understand sry ^^

too confusing

[neon sorrel]

Is there any other good way to destroy a actor without getting a pending kill error? Im trying to use a randomizer script to destroy the actor if it is a certain number, and that works but I get pending kill errors after for some reason and it glitches the actors. (Im currently using just the destroy actor node)

[tight schooner]

@neon sorrel set lifespan to 0.01 seconds can be a quick and dirty solution, but it depends. Pending kill means some script is still trying to manipulate a "dead" actor

[neon sorrel]

Its for a item my player picks up, so im thinking maybe I just have to add isvalid nodes to the pickup code. 🤔

[quiet token]

@tight schooner like this? Its kind of workin, but i dont know why and if there are problems later, this was what u ment?

[tight schooner]

@quiet token if you're trying to get the left and right vectors of an actor, you can use the node Get Actor Right Vector (if I recall correctly). If not, you can Get Actor Rotation and feed the rotation into the node, Get Right Vector

@quiet token in your screenshot I was thinking of Get Actor Rotation

instead of converting forward vector into a rotation

[quiet token]

ok u helped alot, i try out a little, need to learn this shit so i dont have to ask everyday ^^

[tight schooner]

@neon sorrel yeah isvalid might work

[vocal urchin]

Is it possible to line trace to the water mesh actor? I'm having some issues doing so, but I can clearly see it's a mesh.

[neon sorrel]

I fixed it, thank you guys for the help though. Had to do a bit of a workaround but made it work

[graceful hamlet]

Is there a good guide on detecting gamepad events (like plugged/unplugged) via blueprint?

[maiden wadi]

@modest prairie If you mean for stopping the character from moving into things, then no. Other things can interact with those collision shapes, but they will not stop the character. The only singular component that matters for character movement is the RootComponent, in character's case that's the Capsule.

Pretty much ever movement component does that because they move by sweeping the root component of their actor. To get any other results, you'd need to build your own movement component.

[little dirge]

Hi folks, back with another basic question/problem!

I created a blueprint that inherits from Object, and another data-only blueprint that inherits from that.

Then in a UMG blueprint, I'm trying to create a variable that would contain the data-only blueprint. My assumption is that it would act like an instance of the parent with those properties set. However, if I set the Variable Type to "MyType" nothing shows up in the asset browser, same thing for the data-only type. If I set the Variable Type to "Object", I can drop either in.

Am I misunderstanding how to do something like this? Do I need to do this in the graph with something like "Construct from Class" instead?

[little dirge]

Found "PrimaryAssetType" and tried subclassing that instead, since it feels like that's what I'm going for, but it didn't seem to do the trick either..

Edit: Ah, that was correct! I just had to create a Misc->Data Asset instead of subclassing from the primary asset blueprint. 😄

[high frost]

I want to implement a pick up system for actors in such a way that a player can only pick up a character when they see (meaning with respect to camera) it and the actor is within some range like 1-2 meters. Also players must observe information about item before they interact with them, i.e. an item name should pop up above it when it is reachable
What is the best way to do it? So far I have only 2 ideas:

1. In the player character add a long collision box on a springarm on eyelevel so that it moves with camera and to handle begin overlap events with interactable actors. This approach would also require me to handle blocking obstacles so that the player couldn't interact with an item throgh a wall and I'm not even sure if that is possible
2. Somehow use LineTraceForObjects or a similar function to actually trace all items. But that would require me to execute trace functions in the tick event or via timer so I'm not sure if that's a good idea neither
   Also I've seen implementations where interactable items just had their own collision spheres spanning pretty wide so that player could interact with them when he is within a radius of the sphere, but I don't really like this approach as it would require to make big collision spheres even for very small interactable items like coins etc

[hollow dust]

When I use “Get Actor of Class” > into Impure Function that affects it, I can only manipulate the components of one actor through the blueprint. How would I manipulate the components of all the actors of that particular blueprint?
I tried Get All Actors of Class. It returns an array, but I cannot call the specific functions I’m trying to call because it’s an array

[tight schooner]

@hollow dust For Each Loop

https://youtu.be/3A5PjUycPI4

[dawn gazelle]

You would need to loop through said array and call the necessary functions.

Any idea on how to put a water body custom from the new water system at a specific height ? It appears that when packaged the plane/water body will be at 0

[fickle remnant]

what would be the cleanest way to pass a structure to another class in a blueprint? In c++ you could use a pointer thus saving memory

[fickle remnant]

Maybe have a different sensitivity for ADS? Usually games give you the option to assign both

[violet wagon]

Hey @fickle remnant you gave me an idea that fixed my problem! Instead of having my axis value for mouse inputs a 1/-1 I put it at .1/.-1 and it picks up very small mouse movements now! Thank you!

How to check if a Blueprint code has finished loading? e.g. an array has been filled and so on?

Hi! Can I spawn an actor on both the client and the server and then correct the client actor based on the server status?

I'm trying to fire a homing missile but only replicating won't work, it stutters like mad. So I was figuring I could shoot it on both server and client and have it update according to the trajectory on the server

[trim matrix]

I would use an “is input key down” with a branch

[trim matrix]

how do i tell ue4 to place a mesh procedurally
like placing maze assets to create a maze

[tall pine]

i figured it out myself afterwards and managed to do that, only thing left now is fixing the stopping of the sound when i hold two buttons, and release one which leads to the sound not playing despite walking

im quite stuck with that one

[trim matrix]

I could have a fix... add a branch with “input key down (shift)” and if it’s false remove audio but if it’s true add another branch with “input key down (W)” and if it’s false disable audio

Something like that?

[tall pine]

i dont think shift is on focus here, more like when I hold W and A for example, then i release one and it quits the zimer

should i do a branch to vheck if w is held down

[trim matrix]

Oh I thought it was run/walk

[tall pine]

nah running and walk transition works

[trim matrix]

Ok so while holding two buttons if u release one all the audio stop?

[tall pine]

yeah, it breaks the timer by function name if one button is released

i think it would need tons of variables and branchws to set up

spaghetti code check ifs

[trim matrix]

Yea I don’t like use a lot of code in BP...

Mhhh

Sorry I think I can’t help you

@tight schooner @dawn gazelle thank you very much ❤️

Hey all, I'm trying to find out how could I make this happen:
for my VR_Pawn BP I want to attach a plane on the ground with Foliage (grass) but I'm having hard time find a solution to attach foliage inside a BP
I want to make something like a flying carpet as the user moves on this patch of grass in space. any ideas ?!

[odd ember]

gotta admit I have no idea what you're looking for

[tight schooner]

@hollow drift My gut reaction is "that shouldn't be happening"... I've never seen Completed fire before Loop Body. But if that's really happening I suppose the only thing you can do is use a Delay node or Set Timer By Event to literally delay the execution of the rest until the next frame. But it still strikes me as odd and you should try some general bug fixing to see if what you think is happening is really happening.

[odd ember]

if you do this off of anim notifies this will be handled automatically

[blazing vale]

@odd ember let's put it this way - I want to attach a patch of grass (foliage) to my blueprint as a component. (the blueprint will be moveable)

[wild moth]

Hello everyone,
I just upgraded a MP C++/BP project from 4.25 to 4.26 and if I try to open 2 instances in Offline (now Play In Standalone) I get a crash with the main stack:
Assertion failed: !GIsPlayInEditorWorld

Any ideas?

[odd ember]

use a mesh or a billboard? problem solved?

[odd ember]

do you have a postprocessing volume with GI enabled or some such?

[tall pine]

you mean these notif keys used in TP characters?

[odd ember]

in the animBP you can get events for when an animation reaches certain points

[wild moth]

No but isn't that G Is PlayInEditorWorld?

[odd ember]

e.g. when each foot hits the ground

[tall pine]

yeah i know that feature my player doesnt have a model neither an animbp

[odd ember]

no idea. could be either

[odd ember]

I see

[tall pine]

its FP

[odd ember]

best thing you can do is have something that affects the time scale, like a multiplier

so normal speed is x*1.0 and e.g. sprint is x*2.0

you can probably make this a function of your movement speed

and a sine node

[tall pine]

yeah i also thought of that

[odd ember]

the sine node especially is helpful as it will maintain intervals

[trim matrix]

how do i do procedural levels? o.o

[edgy halo]

How do I create a reference to an actor in BPs?

[viral torrent]

@edgy halo Create a variable and fill it using GetAllActorsOfClass for example

[rare hemlock]

I'm learning about anim linked layers, and I noticed that you can send other data types, not just an animation pose. Can this be used to send calculated values like speed and direction from AnimBP_1 to AnimBP_2, and, if so, how do I set those values in AnimBP_2?

[hollow drift]

@tight schooner I have a grid by 13 x 13 fields. Each field type gets generated with a boolean. Those fields have collision boxes. The pawns gets generated after the field has been generated. Those pawns interact with the collision boxes. They read from collision boxes on which field they are standing on. The information is generated in the loop and filled into an array. But this is "already kinda a common issue" since other people have experienced the same. If collision box spawns at the same time as the pawn. the event for the collision box does not fire in time to register the pawn inside of it.

Generally to avoid it i wanted to use something better then a delay for 0.0001 seconds. since this game gonna be a mobile game too, i want to avoid such issues with a smart code. Also what i am looking for additionally is a script to make a level loading which also checks if everything is loaded. i did it over level streaming

so loading and aknowledging is a big topic right now. any ideas or suggestions are welcome 🙂

[cold raft]

No reason why you shouldn't be able to do that - the camera on your character can be moved and rotated so you could move it around as you like (though it might be tricky to get it right with blueprints - maybe have separate cameras setup manually and switch between those) ?

[hollow drift]

I gonna try the set time by event. But generally loading is huge topic. cant find good tutorials since all people are cheating with a loading screen and a delay. what if the device is slower and the delay is not long enought?

[unique hollow]

I'm talkin bout these

[cold raft]

Ah, not sure then - that's developer mode so doubt if they would work in end user games anyway

[unique hollow]

unless you ship your game with developer mode like Mordhau does

and an alternative profiler mode build in Betas like I do

[cold raft]

does https://docs.unrealengine.com/en-US/BlueprintAPI/Game/IsLevelLoaded/index.html help?

[hollow drift]

i saw this already

love the documentation of unreal

what it does, no one knows. what it says it should do i guess?

think we tried already out

replaced it with

[rugged wigeon]

Without having done this before, I would assume you need to pass the Return value output of that function into is Level Loaded

[hollow drift]

so we can manage different levels

dump quick question

[cold raft]

could you make the fields generate the pawns themselves, and then start the level after the pawns are finished? I mean take control of the entire spawn process and do it all in a series of steps where at the very end you enable collisions for the fields

[hollow drift]

how to not do a event tick but check still if it updated

[rugged wigeon]

Throw it on a timer or a timeline. Probably a timer makes more sense.

[hollow drift]

thats what i want to avoid in the first place

a proper level loading as you see in every game

[rugged wigeon]

Then use tick.

But you shouldn't

[hollow drift]

i also thought to make a check object at the end of the spawn queue and ask if it exists

but this is haphazard

there must be a better way

level loaded e.g.

@cold raft good idea

[rugged wigeon]

timer != delay. Timers and timelines can be used like temporary ticks.

[hollow drift]

what if the device is slower? a mobile?

this is just bad practice

[rugged wigeon]

Timer wait a bit, check condition, if loaded, start the game, else restart the timer.

[hollow drift]

also even tick = bad

it goes on every frame

what if your framerate is lower

ill use

or anything better if someone knows

[rugged wigeon]

Your points only apply if you're trying to guess which frame or time the level will be loaded by. You don't need to. You can just check at regular intervals

Yeah, that probably works presuming your event is set up correctly and cancels the timer.

[hollow drift]

this already works 🙂 just general question if there is a better way

[steady minnow]

hi there. I am learning how to build shaders and was wondering: what is the logic behind Camera Position - Absolute World Position ?

Isn't the Camera Position already based on absolute world coordinates

[rugged wigeon]

https://forums.unrealengine.com/development-discussion/rendering/1519060-absolute-world-position-what-exactly-is-it-anyway

[steady minnow]

its a MF to get a Gradient mask from the camera position (used for displacement/tesselation)

ahh so absolute world position is a similar to a "Pixel Depth" but for ALL pixels on screen ?

• for every pixel on screen using this material

you're in the wrong channel technically, #graphics is where you want to go

blueprints are not the same as materials

even if the editor looks similar

actually he's in the right channel, hes trying to pass a variable with the proper information from a blueprint to a material. Showing what he's doing with the material so that perhaps someone can help him get the information formatted in the blueprint to pass it to the material.

Hey everyone. I'm trying to improve my checkpoints with an Animation that plays only on the last activated checkpoint and deactivates the animation of the last one.

[verbal magnet]

how can I get mouse position relative to center of the viewport?

[desert flame]

My character's camera lag just stopped working when i changed the "Max Distance Speed" from default then back to default.

[orchid garden]

i believe default is 10 but it may reset to 0 when clicking the arrow.

[odd ember]

since the position is coming from top left, try and multiply the vector by .5 or divide by 2

[plain flare]

Idk, is there right place. But, my text is showing like that. It is wrapping because auto-wrap is active. But it is so much, and auto-wrap value is 0. Why is that and how to solve ?

[orchid garden]

here's the defaults for camera lag:

[odd ember]

make your text box bigger

[worn nebula]

Does anyone know why my mouse doesn't disappear straight away? https://gyazo.com/dd4de03facebd2136b4c5f9391491fb3

I click once and it removes the widget, but doesn't go back into playing the game

[plain flare]

@odd ember how can i ?

[verbal magnet]

thanks, I used a get viewpor size and divided by 2

[orchid garden]

im assuming the text block is inside a holder, so if you anchor the text block to all 4 corners it should wrap in the full container (be sure to set the values for position/scale to 0 after anchoring to all 4 corners)

[odd ember]

it's your widget that you placed. surely you know how to resize a widget?

[plain flare]

I mean, there is no scale text @odd ember

[odd ember]

player controller doesn't work while the game is paused. I think you have to allow tick while paused in the player controller to make that work, but I can't remember if that was enough

[plain flare]

@orchid garden yes it is inside somethings

[zinc spoke]

Hi everyone. Can someone recommend a good tutorial for Pawn Movement Techniques with Blueprint?

[worn nebula]

How can I allow tick while paused?

[odd ember]

it's probably your text justification settings then

[tidal venture]

I created a TArray of UObject instances for one of my blueprintable classes. Now I have the problem that I seem unable to assign anything to it in the editor.
TArray<UQuestTaskCondition*> Condition <-- this is the member
The editor allows to add members to the array but i cant assign anything. How would I spawn a UObject instance in the editor?

[orchid garden]

and you want it to fill the full container space?

[plain flare]

No, Im trying to fix auto-wrap

It is auto-wrapping so wrong

[simple sky]

In BP functions do local variables already reset to their default on entry?

[worthy frost]

yes

[orchid garden]

not really, its autowrapping properly

[plain flare]

1 minute

I closed autowrap

[orchid garden]

with how you have it the text widgets width is being scaled to the first word, and only expanding to the next word thats larger.

[plain flare]

and I want to get text like that

But also, auto-wrap important

because if my text so long, i need it

[orchid garden]

yes i get that, now listen, how much of the container do you want your text to be able to fill if its extremely long?

[plain flare]

.

which container, text block ?

[orchid garden]

the container that the text block is in

[plain flare]

full off can be fill

[orchid garden]

okay then you need to anchor your text block to all 4 corners

when you click on anchors its the bottom right achor

then set the offsets all to 0.0

then in your container, go to padding and add left, right, top and bottom padding for the space you want between the edge of the container widget and the text block

[plain flare]

what is anchor

where to set i mean

[plain flare]

got it

there is no anchor

[orchid garden]

on the text block

[plain flare]

on text too

[plain flare]

.

On this image, all of the pointeds

[orchid garden]

oooo ooo

its because its in a border

okay simpler then

set horizonal alignment to the last one for the text block.

[plain flare]

for text right ?

[orchid garden]

yeah

then down in apperance, set text justification to center

[plain flare]

Yeah yeah, it worked, thank you. You are rock !

[orchid garden]

np 🙂

you might need to adjust the padding in the border for really long strings of text.

Doesn't look like there's any way that I can see you can make a BP function work like this. You could do it with an array and a make node before it if you really wanted to and then loop inside the function.

[dawn gazelle]

What blueprint are you placing that Left Mouse button in?

This may be what you need? Construct object from class.

Does anyone know how I would achieve smth like instanced timers ?
I wanna apply Temporary Buffs and Debuffs which can stack upon each other...
For example you start out with 100 Health then receive a debuff which reduces it by 30
you have 70hp for as long as the debuffs goes... but If you then receive a buff which add 50hp you will have 120 until the debuff disappers and then it will be 150hp

Hi! I'm trying to set up Face Live Link in UE 4.26 and have connected my iPhone 12 Pro to the AR Sample project and it works just fine. However, when I try to add rotation it doesn't work. The reason why seems to be because the "Evaluate Live Link Frame" node's output from the phone doesn't seem to respond to any properties with the names specified in the documentation for face live link (headYaw, headRoll and headPitch). Is the documentation just out of date or have I missed something important?

tldr: evaluate live link frame node does not output any value for pitch/yaw/roll. Why?

https://docs.unrealengine.com/Images/AnimatingObjects/SkeletalMeshAnimation/FacialRecordingiPhone/LL_HeadRotEventGraph.png

This comes straight from the documentation: https://docs.unrealengine.com/en-US/AnimatingObjects/SkeletalMeshAnimation/FacialRecordingiPhone/index.html

Nevermind I hadn't enabled "head rotation" in the app settings on the phone

[gusty shuttle]

Quick, off the top of your head, what is that node in a sound cue that can change pitch and tone randomly. Is it Random?

[fallen tartan]

its modulator

[gusty shuttle]

To answer my own question it was Modulator

Aye, thanks @fallen tartan

[fallen tartan]

random select a random sound from the inputs

[gusty shuttle]

indeed, I would need a library of sounds, then feed it into a random. Modulator is just what I need, spanks!

[little cosmos]

I am experiencing the weirdest thing

Can't toggle visibility for static mesh of Lobby Actors array

But the one above is just the same with a difference actor.

Cannot access its static mesh . What's going on?

[dawn gazelle]

Do get Static Mesh first

[little cosmos]

first how?

Notice the one above works

[dawn gazelle]

when dragging off the loop, begin typing "Get Static mesh".

[little cosmos]

I have tried.

[dawn gazelle]

Ok, then the thing is, you need a reference to what component it is you're trying to toggle visibility of.

[little cosmos]

static mesh component of Lobby Actors

but im doing it just the same above and it works!

[dawn gazelle]

What class is the "Lobby actors"?

[little cosmos]

Actor

[dawn gazelle]

You won't have an appropriate reference then.

As not all actors have static mesh component.

You can cast the array element to the appropriate class.

[dawn gazelle]

Open up your "BP Lobby Entrace..." whatever that BP is, and take a screenshot of its components.

Example:

In my example above, I'm using an actor of class "BP_ALS_Minion". I can pull off for its "Static Mesh" component because the class has this particular component (as you can see in my screenshot above)

[little cosmos]

is it any different?

Take alook

[dawn gazelle]

Your Lobby Actors variable.... If it's set to class "Actor" it won't work as "Actor" doesn't necessarily have the static mesh.

[little cosmos]

The two actors do the same thing

one above works

I mean they're built the same

[dawn gazelle]

Hover your mouse over the array box on both. it'll tell you the type of variable.

[little cosmos]

WTF

It was Actor -.-

Fixed now. Thanks a lot dude

[unborn maple]

trying to check if the start round button is push and if the round begin timer has reach 0 to enable tick to listen for an input or should i use timer by event? as i need to enable in put in the blueprint for the key to work. so i dont want the key to be active when the round hasnt started

tick is still running when i hit play and doesnt stop like the tutorial i watch

[gusty shuttle]

Question: Do I 100% need to manually place a Level Sequence into a level, or does Create Level Sequence Player create that in the persistant?

[unborn maple]

never mind i found out why it kept going i didnt set the tick to false at the beginning of round

[dawn gazelle]

I think this should do the trick https://blueprintue.com/blueprint/o5ksg2r0/

[sand gazelle]

Any idea why you must use game instance to spawn a pawn rather than just creating a SpawnPawn event inside the game instance? A tutorial has me do both

[dawn gazelle]

You don't need to use game instance to spawn anything.

[solemn parcel]

@dawn gazelle Thanks looking into it 😉

[sand gazelle]

@dawn gazelle How would I spawn a Pawn that is not in my level already?

I have this as the base

[little cosmos]

What this means?

been gettings these lately when going back and forth my levels. not happening in packaged build

[dawn gazelle]

This can be used all over the place. It doesn't have to be done inside of game instance.

[sand gazelle]

Ahhh

I wonder why tutorial made me use it in game instance

it has me use that block in this one instead of the base that I just showed you

Like why put that last block in the base when I already have this. its all under game instance

[dawn gazelle]

Are you asking why does he put this in?

[sand gazelle]

yes

[dawn gazelle]

That's a call to this red event.

[dawn gazelle]

Do you have a level named that in your game somewhere?

[little cosmos]

Yeah I fixed that already

Had an old name reference somewhere

[sand gazelle]

This is a custom event I created in this same game instance

[dawn gazelle]

Events can be called whenever you need them to do something and are not fired by default. I'm not sure of the intentions of the tutorial as to why they are explicitly getting you to use specific areas to spawn your objects.

[sand gazelle]

ooh okay

well this one is on the unreal engine learning website and its the VR development course

the intention was to spawn the pawn but detect if you are using the headset or a controller

[sand gazelle]

So you must call an event to work it seems. I thought you called events by creating cutom event lol

Im learning 🙂

[dawn gazelle]

Well Game Mode is usually the place to handle spawning in players as you can also get a reference to when they are entering the game, so it makes sense that it would be there. You keep saying Game Instance but that's another type of object itself which is effectively above the Game Mode - it can store variables and do things that can travel between levels - for example, playing background music that isn't interrupted when the level changes, or in your case, the storing of the VR settings.

[sand gazelle]

ooooh

I meant Game mode

[dawn gazelle]

Game Mode can be the same between levels, but everything stored is lost when you move between them.

[sand gazelle]

thanks man!

[unique hollow]

I got a health system in place, I want to add healing to my game but I don't want it to ever go over 100

[dawn gazelle]

Clamp

[unique hollow]

the current way I have it is that it takes the heal value + current health then sets the health as such

oh

yep

that was easy

[dawn gazelle]

🙂

[sage urchin]

Anyone made keyboard focusing a WebBrowser widget work?

What's the preferred way to share logic between animation blueprints?

[gusty shuttle]

I have a question about level sequencers.

Do I have to place the actual sequence asset in the level OR can I just use CreateLevelSequence

[open acorn]

I'd really love to see a list of examples of things that go in game mode, player controller, and character.
For example:
Game Mode's list of example would start with "top score" and "game time remaining"
Player Controller: player's input actions like key presses
Character: Hit points... and now I'm not so sure because all of my inputs are in the character and not the controller...
Where's the giant list of where these things should go?

[odd ember]

controller is input and camera

game mode is your ruleset for the game

player character is whatever attributes your character has

[open acorn]

where would you put respawning in in a multiplayer game?

[odd ember]

you're in the wrong chat, try #cinematics

[dawn gazelle]

It's hard to define what needs to go where as where things need to go is dependent on your design, and what you want to store where. Rules of thumb:

Game Instance: Anything that needs to persist throughout the game between levels. Items here are specific to the instance of the game running and cannot be accessed by other clients.

Game Mode: Rules and Scoring that should not be replicated to clients. Items here are not replicated to clients and cannot be accessed by clients.

Game State: Any values that are not specific to any individual but may need to be accessed by clients. Values stored here can be replicated.

Player State: Values relating specifically to players that can be accessed across clients. This can be used to store things like a character choice, or what build the player is using. Each player get their own player state, and values stored here can be replicated to other clients.

Character: Movement controls (as each Character could potentially have their own movement settings). Characters can store their own values, but if they are destroyed (such as after they are despawned due to death) then those values are lost. Values stored here can be replicated.

Player Controller: Can be used for Menu control, though some movement could be done here as well. UI can also be stored here. Controllers are present only on the owning client and on the server, but not other clients, so you cannot reference other client's controllers from a client, only on the server.

[dawn gazelle]

Probably game mode.

[odd ember]

input should be handled on the player controller technically, whether movement is handled per character is irrelevant to input however

game mode has specific functionality to handle respawning (as long as you're not deriving from GameModeBase)

that is especially useful for multiplayer

[open acorn]

so game mode is not replicated? but respawning needs to be replicated, right?
Yea I'm trying to make multiplayer respawning atm

[odd ember]

game mode also has functionality that prevents race conditions and shows that the loading process definitely dictates controller to have control over input as opposed to character

[open acorn]

maybe talking in specifics would make it more clear... like in Rocket League the score board and time are replicated but I would have thought that would be in gamemode

[odd ember]

at least that is what epic implies by them

[dawn gazelle]

Spawning something on the server typically spawns on clients as well unless you're specifically spawning it only on server.

I think

[open acorn]

i can't think of anything that would be only spawned in on the server and not replicated to the clients.

but lets not get distracted

[odd ember]

I suppose that is why spawning should only happen on authority

[open acorn]

for example in rocket league -
the scoreboard and time "would be in" game state?

[dawn gazelle]

You want the score board and time in game mode, certainly, but you can then make a copy of it in the game state. The idea here is that you want your scoring and logic somewhere where the players cannot access. If you had it in the game state, players could access it and mess up things on their client.

[odd ember]

most likely in game state, as it gets flushed

but then it depends

[open acorn]

ok so game mode is replicated but it is protected by default because it is only run on the server?

[odd ember]

generally there's only a few classes that persist data across level transitions in both SP and MP, so you have to consider where you want to put them

[dawn gazelle]

No

Game mode is not replicated.

[odd ember]

I reckon #multiplayer would be a better place to ask really

[dawn gazelle]

It exists only on the server.

Anything gameplay related that players should not have access to should be stored in the game mode.

[open acorn]

we can continue the discussion over there if you want

[dawn gazelle]

So a "score" or "time" in the game should not be touched by players.

If you want the players to see the score and time, you can do that by setting a similar value in the game state, but do not use the values stored in game state as a means to determine when the match is over.

So they do not have direct access to the variables that are controlling the game.

[open acorn]

game mode is only run on the server so clients can't change it even if they tried

[dawn gazelle]

Correct

[open acorn]

lets go over to multiplayer

[empty laurel]

Anyone have a good reference doc or tutorial for triggering events from sequencer? I tried this in my last game jam and was trying to change levels at the end of the sequence and it would not trigger consistently.

[fading raptor]

Does anyone know how to change character Z rotation based on character velocity?

I want my character to slightly tilt when he is jumping

Kind of like minecraft foxes

[odd ember]

when you say z rotation do you mean pitch or roll

but also, generally changing the rotation of the character you're controlling is not a great thing

it's better to do this in animation so it just looks that way since anything you do with the character otherwise affects movement and could have side effects and bugs to resolve for little gain

[fading raptor]

I meant the pitch, but you're right about just making it an animation, however i dont think it would work if I added multiple jumps

[odd ember]

animation blending exists

[fading raptor]

true

[odd ember]

but anyway the point is that you don't want to make it based on the physical constraints

it's just something that is cosmetic

[fading raptor]

Makes sense

oh boy now i gotta create the animations 😫

[exotic cradle]

So Im trying to spawn one specific object in the middle of a collision box I call EditorArea. Now that part works well the problem is the item is spawned in according to my print string just not the mesh associated with it. I currently have a masterbp and a childbp as shown. What am I doing wrong? https://gyazo.com/0006129c9fe2624858ec03da49b3d76c https://gyazo.com/76d96f296f0abc20da0804ef5d8b98c2 https://gyazo.com/78c885cb6aced2b109096de79bd421d3

I have a feeling I didnt setup my childbps correctly

[dawn gazelle]

Relative transform would be the boxes' own position relative to its parent object.

[exotic cradle]

Yes. If I use any other location or transform it doesnt spawn the object in the middle of the scene. I tested it using another blueprint I have with a mesh associated with it and that got me the results I wanted

Im just trying to get the correct mesh I want spawned upon the level loading with the stats that I have given them from my data table.

[dusk dust]

Is there any way to access a materials output in blueprints?

[tight schooner]

Materials output? Maybe render it to a texture and sample the texture with a blueprint node?

I have some vague recollection of a node that samples a provided texture, getting the pixel color value at some coordinate ...

[rain horizon]

I've got this set up to automatically do a second jump once the first jump apex is reached, while the jump input is held down. Now, once the character lands, i want it to loop as long as the jump input is still being held. I've tried numerous options and i can't figure it out. Any suggestions?

[maiden wadi]

@rain horizon You're going to need to tie that in with OnLanded

In short, make your jump a function that both InputActionJump, and OnLanded can call.

Then in OnLanded, check if the keys for Jump are being pressed currently, if they are, run that jump function again.

@rain horizon Also, don't bind multiple times like that.

[odd ember]

@maiden wadi perhaps you've investigated this. I see wires crossing over from execs, and while it is certainly bad practice, is it actually going to have the variable saved off of the event node?

in the above screenshot

[maiden wadi]

@odd ember You mean from Key to IsInputKeyDown?

[odd ember]

yes

[exotic cradle]

So why would my children BPs not be able to display the static mesh associated with them? I ask because I just ran a print string for every outrow variable inside my children BPs and they all match whats in the data table for the item but the mesh is the only thing missing for some reason.

[sand shore]

@odd ember it sure will

100%

[odd ember]

cool

I mean don't get me wrong, I'd never do this myself or ask people to do it, it's just an interesting technicality

[sand shore]

it's also a bad practice in the general case

[odd ember]

natch

[maiden wadi]

Yeah, Events seem to save their arguments in local variables or something that nearly anything in the graph can use. Each firing of the event updates it.

[sand shore]

yup

[odd ember]

so in that case runtime that would easily break though

[sand shore]

It can break though, with a certain optimization

[odd ember]

since you could press jump while double jumping

[sand shore]

That's totally fine?

Yeah it breaks but the outcome is the same

[odd ember]

yeah

I see

[sand shore]

it's a very niche example where the broken state is aligned with a desired state

but if you were to enable a particular build option, this would break in a bad way

[odd ember]

that's what I was thinking

[maiden wadi]

It's worth noting that a lot of BlueprintCallable stuff does the same thing. For example, you can cast on one execution line, then run another execution line and get that same casted pointer to use.

[odd ember]

a sort of inverse gimbal lock scenario

perhaps a

goldilock scenario

[odd ember]

I was aware of this, but the case for callables is much simpler since it requires execution before hand

it does not trigger execution in the way that an event does

[exotic cradle]

https://gyazo.com/9fef6b5f52a75a248664266273c0dbf1 So after setting print string for just about every variable and checking if the "mesh" was valid through a branch which sets ObjectTrue or ObjectFalse after validation I get that the object is valid but it still remains invisible in my scene. Inside each child BP https://gyazo.com/5bb9f672fa566986ce2bb63d55ab31f3

[sand shore]

@odd ember @maiden wadi Entry points and function calls both handle right-side-variables the same way

they should only be treated as valid only in the same callstack, but they technically work because the engine doesn't overwrite the params

[rain horizon]

sorry guys, just running through the responses. i'm pretty new to all this so i'm not 100% clear on everything that was mentioned. @maiden wadi what are you referring to when you say don't bind multiple times?

[unique falcon]

don't worry, it's okay to be new 🙂

[maiden wadi]

@rain horizon

Reset the notify per jump, but don't bind each time. Only need to bind an event once.

[rain horizon]

ah i see what you mean

[maiden wadi]

Hmm, odd. Onlanded calls too soon to jump again.

[rain horizon]

is that why that didn't work? haha

[exotic cradle]

Would it be possible that because of a box collision my item is said to have spawned with a mesh but due to the collision box the mesh is never rendered on the screen?

[maiden wadi]

@rain horizon This works. But I'd find a better way than a delay at some point.

[rain horizon]

i started with a delay but i scrapped it because if i let go of the input and pressed it again before landing sometimes there was delay before jumping again

i guess it wasn't in this form

but not ideal like you said

so i'm understanding correctly, the jump key pressed function is more efficient than grabbing the key from the inputaction event like i had it?

[dawn gazelle]

The thing is you could theoretically run into a condition where you don't have the key value from the jump input action set.

[sand shore]

this seems like trying to detect that jump is being held on any particular frame

the function could be called from anywhere, and if any jump key is pressed it would return true

[rain horizon]

hmm

i guess i don't understand that. if the key value isn't set wouldn't it be impossible to initiate the event?

[dawn gazelle]

That's why I said theoretically.... One such theoretical example - you jump, before reaching the apex you change your jump keybind, your function no longer works. Not likely to happen, but it can happen.

In the end, it's still not a good idea to cross pins across execution paths for just such a reason - it can introduce bugs and unintended behaviour.

[rain horizon]

oh you mean from one node to another

gotcha

[knotty dirge]

Question: Is there a way to visualize (and possibly use) curves in Unreal Engine? Not the kind of where you put your points, but through mathematical formulas, linear, quadratic, logit, ect

[dawn gazelle]

If you want to make up the math execution, of course.

[knotty dirge]

how? yeah I would provide a formula and I'm looking for a way to visualize it

[dawn gazelle]

One example? You can create an actor that leaves a trail based on where it moves over time. You would then have to feed in what position you want that actor to be in based on the time. Ex: Have your X as value. Y axis as time.

Then just move your actor to each point and you'd have a visual example of that curve.

Probably not the best way of doing it, but it is a way XD

[rain horizon]

thanks for the help/tutorial y'all

[maiden wadi]

@dawn gazelle @rain horizon You also run into issues where you may have more than one key for an event and you may want to simply know if ANY jump key is pressed. the one from the event only detects the exact key pressed that initiates it.

[exotic cradle]

Is there anyway to assign an overlap collision box to a mesh through bp?

[rain horizon]

that makes sense and is good to know

thanks

now if we just knew why OnLanded called too early to work by itself i'd be totally content with this aspect haha

this whole thing started because i wanted to use one of the triggers on my gamepad as the jump key, but obviously they aren't meant to be hit repeatedly

[maiden wadi]

@rain horizon Use Event OnMovementModeChanged instead Seems to call later. I think it has something to do with the jump count not resetting yet.

@rain horizon This seems to work well.

[rain horizon]

yup, thats what i got now, works perfectly! thank you!

i did include a check to see if the jump key was pressed after the DoubleJump event as well, so it doesn't just do a double jump automagically

[dawn gazelle]

🤔 is it ok to bind to an event dispatcher on a keypress and unbind on release?

[orchid garden]

i just did a little boolean check for double jump, set it on first jump if not falling, and do normal jump, then if first jump active launch the character for the second jump, unset the double jump check. seemed the simplest way to do it.

[sonic cipher]

https://gyazo.com/b73f6ce20a675f17bed0c5716036705e why the anchor by default is under the screen ?

[orchid garden]

well technically its not, its anchoring the top left corner of your widget to the anchor point.

just subtract the height of the widget for the Y offset, i.e. if your widget is 50 tall, put in -50.

[native plover]

Anyone can help me with IK? I followed this tutorial and im having this issue. https://www.youtube.com/watch?v=0-mkUKtYJbE&ab_channel=UE4TutsForYou https://i.gyazo.com/03cad8b0c920ebaa789e26738e96f26c.mp4

[umbral shard]

Is it better to have one AI Controller/Behavior tree for all enemies or should I have a Ai Controller/Behavior trees for every unique enemy type?

[sonic cipher]

thanks you 🙂

[orchid garden]

looks like its working right, its just the camera placement on the head is showing the arm when it moves over to the left, guessing your right arm does the same thing. probably the best way to counter that would be to tilt the head when the hand is moving. Note though, when you use a actual character model with that, its going to behave a little differently then the manniquin does.

[warm ermine]

Anyone know how I'd enable duel wielding? I followed this tutorial. https://youtu.be/0GlC4z7LIWU?t=955

True branches off to the execution mainhand 2s execution . I can physically dual-wield wield this way. The issue is my inventory and equipment. I cant transfer main hand 1 slot to main hand 2.

Probably has something to do with update equipment . Cant figure it out though 😅

[quiet token]

Hey! I would like to linetrace not just to my forward vector, i want it to have a offset to the left for example. Its kind of working, but when i turn around at some point its tracin on the opposite. Just imagine that i want the trace not to go to my crosshair, but for example -100 on the y. Any ideas what i'm doin wrong? Do i have to make somethin ABS?

[trail rampart]

Use Right Vector with negative value (so it is left) and combine it with forward

[quiet token]

sry i dont quite get it

mom i try a little

[supple dome]

you get 5 meters on your front by Forward * 500, to get 100 to your left you use Right * -100

then just add

[quiet token]

Like this?? isnt workin xD but i'm pretty sure thats not what u ment

[trail rampart]

you didn't plug the last vector

[quiet token]

ahhh nice thanks

Sry again ^^ I tought now i where able to drag my player to that point we're just made. But when i do this he's just pullin me to 2 points in the world

not relative to my position, but its the same value...

This is one of the moments u regret beein bad in math xD

[dawn gazelle]

I don't think you want to add in the world location * 100000 into the Add Force node.

[quiet token]

I want my player to get "pulled" to that point wich is next to him

the lower part works fine for the railtrace, but when i add force he's not doin it relative to me

[dawn gazelle]

When your character is standing still 0 force is being applied. If you applied force to his forward vector, he would move forward.

[quiet token]

its kind of that he's pullin me just to north and southpol

[dawn gazelle]

If you're wanting to get pulled to the line trace position, then you need to get the value from the line trace on its output.

[quiet token]

but istn the lower part, wich if feed into the "End" of the raycast the ending point i want to have?

i mean, this is the endpoint of the vector, this is the place i want to get drawn to

with the other output its still the same

[dawn gazelle]

You have Event Tick. This is one execution path. In your example, your event tick is connected to a line trace that starts from the camera position and is ending to wherever that math is point to. That's all that you're doing with that Event tick.

Then you have your E key input. You're saying forcefully move the character based on the math that you're calculating. It has nothing to do with the line trace.

[quiet token]

i know

i used the raicast to visualize the point

so i can see it

now i want to get drawn to that vector endpoint, wich i fed into the force

but the force isnt with me xD

now i tried to just put an collider at this place, without all the math

but he's still not draggin me to that location

maybe i have some issue with the force

[dawn gazelle]

Again, the point being, you're applying force to your character that contains the world location data. That doesn't make sense.

[sonic cipher]

can someone help please ? mmy HitActor doesn't delete https://gyazo.com/e4fdfa73bd82d692ed0fc8e1ea247e82

[quiet token]

ah okay

now i maybe get it

ahh, when i feed it without the world info its working
