blueprint

[zenith temple]

Thanks Datura!

[loud cipher]

anyone know how

i can get chromatic abberation in ue4?

Like get it to fade in

Ohhhhhhhhhh

Thanks

Yeah

[zenith temple]

is there a simple way to combine these, as for me the mesh is all 1 skeletal mesh so would be nice to just hide by bone only for yourself:?

[wild laurel]

trying to convert my project to top down where my char always faces my mouse cursor.. quick googl search shows this:

any other ideas or ways to accomplish this? I assume it has to be on tick unfortunately? Or maybe theres another way?

[timber knoll]

that's a solid method, depending if your camera is locked or not you can do it on input only (when you move cursor)

with tick, it also works if you move your camera

[spark steppe]

depends on your character, if you have turn animations you want to use control rotation

instead of force rotating the whole actor

[craggy turret]

how do I get a refference to the enemy AI?

It wont let me use the usual

[cold raft]

you have to pass a reference to the Cast to EnemyAI - the input pin is not connected

[craggy turret]

Ik, but it wont give it to me

it only gives me floats and boolean from the enemy ai

[cold raft]

When you spawn the enemyAI, save the object so you can reference it later. Otherwise - if you are calling this because the enemy hit your character, there will be a place you can get "actor causing damage"

[craggy turret]

im calling it bcs i want it to show the enemy hp

and whenever it gets hit it should deacrease

ill try that

[urban zodiac]

How do you calculate the look at rotation that is half way between two locations?
FindLookAtRotation exists and works.
p1 ------------ | ------------- p2
So basically I want to look at the halfway point of those vectors. I figured a simple lerp with 0.5 alpha would do but that didnt work

[lone cradle]

Hello, I'm having trouble with this AI node in blueprint. Is returning OnSuccess even if the AI has not reached the acceptance radius and there is no path on the NavMesh towards the player. Shouldn't it return OnFail?

I have allow partial paths disable on the project settings btw.

[lone cradle]

(p1 + p2) / 2

And you look to that point

[urban zodiac]

tried.. literally does nothing

which yeah.. i know

thats not how math works

[lone cradle]

I mean, yes, its literally how math works

[urban zodiac]

maybe its something with the FindLookAtRotation

[lone cradle]

You can add points in space, divide by two and get the middle point

[urban zodiac]

This will rotate the camera to exactly look at the impact point as if I did nothing

[craggy turret]

how do I save the object?

which kind of

variable

like this?

im trying to make a widget showing the healthbar

of the enemy

and im having trouble getting the object

[urban zodiac]

nevermind I figured out my problem I think. Should have saved a seperate vector instead of using get world location. Since that will be a vector perpendicular to the target locatio

[cold raft]

When you spawn the enemy, it will have an object output. Save this by dragging out the pin and choose Save as variable (though you may want to save an array of them)

[near yarrow]

im having some serious trouble with axis remapping

[craggy turret]

alright

yeah i still dont get it

[cold raft]

is it because you have the S key mapped to Forwards/Back as well as None?

[near yarrow]

no

ive been ressetting the ini to original in between tests

i just tried hooking it up a different way just to be sure it wasnt because the element was removed before adding

here is the result

the scale gets all screwed up now

actually in game that s was an e

lol

it doesnt make sense

this is happening inside of a widget

each widget is created for each input action and axis index

since axis mappings have index

i have hooked this up all day and no dice

that first s under forward back was e in game

i need to test input name and print them out to make sure thats not getting screwed some how

name is printing out fine

i have a feeling this is bugged some how

lol the keys dont even match what i put in

its like its changing inputs that it should not

id like to see a proper example of axis remappings. these videos on youtube all give similar issues

almost as if these widgets are screwing with each others input variables

cant print a key unfortunately

maybe its because the index changes after removal

omg

ofc

i need to update index some how

shit

[cold raft]

Is the key mapping being acted on in different blueprints? I had a tricky bug once - a mapping had events in both the player character and player controller

[near yarrow]

no

we just tested it

its the index number we pass in

once we remove the key the next index in line moves back 1

i would need to keep track of that or rethink everything

all that should be changed is those .ini files and the widgets themselves are changing it

all action mappings work fine

but the all only have index of 0

so no reason to pass in index for action widget

the axis widget needs that index to sort out multiple keys

[cold raft]

Your video shows you changing key bindings - post what those blueprints do.

[near yarrow]

ill make another one with robot font so i can pass in the name appended with scale

the scale of the input is passed in

file to big hang on

this is what they were

this is what i change them to

but the ini shows this

i only need the index when i create the list of the widgets

using that index inside the widget is a no no. i need to just pass in the original scale

im not sure how im going to get around it but i know why its happening now

i use the index when i create the widget and thats it. i create the input to be removed and replaced by the index then after that it works now

🙂

nvm

it only works if i change them in a certain order lol

but im closer

[drowsy ridge]

hey all what's the best method to check whether a player is moving forwards, backwards, left or right?

[near yarrow]

what do you mean? multiplayer wise or locally?

there is a thing called get last input vector

i use that to find out which way a player is supposed to boost

irc i had to replicate it for multiplayer

[drowsy ridge]

singleplayer

[near yarrow]

are you checking for input?

[drowsy ridge]

direction + input

[near yarrow]

this is how i do it

im using camera direction tho

you might want the direction the actor is facing

[drowsy ridge]

Gotcha

thanks a bunch!

[near yarrow]

heres one that picks inbetween capsule and camera depending or not if they are moving on the ground or walkable surface

just incase you need them to move toward the direction you want if they are in the air

camera based will slow them down the greater the angle of up or down gets

[gentle urchin]

Hows the states working for you? Regarding the overlap start location i think you'd need to either trace it or register to the overlap event (bind to event begin overlap on the weapon) altho it can be a tad tricky i suppose. I assume 'get overlapping' is updated by that specific event so it should be accessible

[quartz pawn]

hi, so I have this asset that works in UE 4.26 but not in UE5. now the error is "Access None trying to read property PMM Game Instance". whenever I try to reference it in a widget blueprint, it says "Cannot create components from assets in a non-actor blueprint"

[livid vessel]

Any Ideas, why On Mouse Button Up wont fire?

[tepid cipher]

anyone figured out the new bug with UE4 and dual screens? I have to restart it every few hours, the main screen does this dodgy see through thing for the blueprints and I can see behind it, I cannot rightclick or see what there, on the main screen, I'm running 64GB ram, 3090 and an amd 5950x.

Pic related is what happens when you right click, I have to restart the project, also I have to take a pic with my phone to capture it.

I do know the problem is fixed if I use a non-main monitor.

Also the pins when you drag them feel like it's software rendered for the main display, when I move them around they feel like they go 10 FPS, my second monitor is smooth.

It's an absolute bizarre problem that can't be really googled, I noticed other people had this issue.

When I stream it doesn't appear on the stream, but it does for me, same with taking pictures and things.

[formal wren]

What is better: 1000 components with tick enabled or updating all of them in a for-loop on the parent actor?

[tepid cipher]

I wouldn't bother with those bind events, the drag and drop is buggy as well, and has been since 4.18 I think it was.

[livid vessel]

Is there a work around like on Preview mouse Up?

[tepid cipher]

The problem with UE5 is that you don't know what works and what doesn't, it sounds like the game instance isn't set.

[tepid cipher]

well bind events are always on tick, so, what I did was make my own through event tick

it sounds like you're using it on UI

brb going to update my drivers

I can't stand this damn UE4 glitch

[livid vessel]

These two are also no workaround

[tepid cipher]

@livid vesselin the blueprint I have a boolean that has "isLeftMouseDown" and toggle that with a mouse click and hold, then on an event tick I trigger what I want through a function, that's how I manage to get the drag and drop to work like a drag and drop

I am going to revisit that though in the coming months

[livid vessel]

Also wont work for me XD

[tepid cipher]

let me have a look at that

that mouse pointer event you don't want to use

create an artificial one

I'll brb

[livid vessel]

how?

[tepid cipher]

reinstalling my GPU drivers

settings > create input

then use that to toggle a boolean

[livid vessel]

Ok i will test if this will work for what i want

[vast crow]

No way to move an event into another event graph of the same class?

[random ermine]

Hello. I'm trying to control the LOD level of a blueprint instances. My situation is that I am scattering a bunch of trees with LODs in the level with houdini engine using point cloud, then I bake the result as a blueprint. In the blueprint, I saw it was using hierarchical instanced static mesh. I want to be able to create some sort of volume. Then within that volume I can lower down the LOD level. I saw there is a "Set Forced Lod Model" node but it doesn't seem working to me. Any ideas?

[gritty elm]

you can use get actor forward/right vector values to verify this, also you can normalize or use vector length to check this

the other method is to see the values of input axis where you are adding input movement

[gritty elm]

there are many ways, it depends, for now you can use get actor of class or get all actors of class ( if there are multiple enemies ):
https://www.youtube.com/watch?v=XLwseuHI-wk&ab_channel=MathewWadstein

probably you have two classes in your project content folder with same name

[earnest tangle]

iirc if you want to change the antialiasing method being used you have to use one of the console variables for it

there's no way to change it other than that

yeah

[azure sparrow]

Hello i am recently getting this error wehnever i am adding a new plugin to my project

if the engine crashes that plugin fails to load

[terse latch]

I am working on a homing pickup or item magnet effect. If the item is placed in the level then the homing effect works. I made it as a pawn as it seems to work, kind of. But if spawned after a enemy is killed it does nothing and sits there. might anyone have any ideas?

[timber knoll]

do you use AI controller?

you should check if the controller is enabled on both spawn and placed (auto posses)

[terse latch]

hmmm no tho i can give it a try. I was using float movement with pawn sensing.

[gentle urchin]

You can also do it with a simple collision sphere + timeline

On overlap -> start timeline
Lerp from actor start location to player location , with alpha coming from the timeline

[timber knoll]

well not even a timeline

since that would move very close objects to you over same duration as a far object

[gentle urchin]

Depends on the speed setting

You could check distance for playrate

[timber knoll]

can just move it with a constant velocity

hmm yeah like that would work but a bit overkill imo

[gentle urchin]

But y, i agree :p

Constant velocity should be fine aswell

Many roads to rome

[terse latch]

I think I found it thanks!

[eternal ivy]

How do I pass a variable from widget blueprint to a character blueprint? I have this in my widget

This in my character blueprint

and this in my character animbp

I want clicking on ui buttons to change variables that will change animations in my AnimGraph

press 'x' triggers dance animbp state, press 'y' triggers bow animbp state, etc

[gritty elm]

from return value, you don't even need to cast, just type variable name that you want to get inside your character blueprint

do like this @eternal ivy

[trim matrix]

That wont really work for what hes asking.

[trim matrix]

You need to promote the returned Widget to a reference variable.

[faint pasture]

Dancing would be a montage. AnimState_Bow would be an enum

[trim matrix]

Thats assuming you want to get into using Anim Montages. (Which would be the correct way to handle that). It is a different direction then the one you are heading though.

[eternal ivy]

Thank you all

I will try

@gritty elm When I start playing, my UI spawns and it accepts the initial state of dance, which is false. When i click button_0 dance is set to true, but the animbp isn't triggered, How do i refresh the dance variable connected to the event start after i click the UI button_0?

[twin ibex]

Not to interupt the current conversation, but I'm new to unreal and I was wondering about good resources to learn blueprint basics to get started on basic 1st/3rd person combat

[trim matrix]

Like i said, What G33k360 wont work for what you need.

His solution didnt include anything for after the game runs begin play

In order to accomplish what you want, you need to make a widget variable.

Right after you construct a widget, you typicly want to promote the ReturnValue of the ConstructWidgetOfClass node to a variable

If you dont, you will never ever be able to pull data from that widget ever again

so what you need to do..

That will create a new variable for the Returned Widget

[verbal bobcat]

Hi everyone! So I have a problem on a disconnect button. when someone joins a server and then wants to quickly disconnect (maybe joining by mistake) they press the disconnect button at witch point it destroys the session but do I need to change level or is there another way around it so it cancels the connection process?

[trim matrix]

Then in order to retreive data from that Widget (Check if the button has been pressed on the Widget or not)

You would...

Something like that.

The important part is the Get Widget Reference.

The variable that was created might not be called Widget Reference.

[eternal ivy]

Do I put this part in the animbp?

[trim matrix]

So you are gonna have to type Get [Whatever the engine named that variable]

[eternal ivy]

it is now 😄

[trim matrix]

lol nice

yes this part goes...

https://media.discordapp.net/attachments/221798862938046464/891769957023645696/unknown.png?width=1139&height=311

this is what im reffering to

my recreation isnt the same at all but i hope you get it xD

The only things that matter in my recreation are the Cast to BP_Dialoge, then getting the Widget reference from it

Oh lol also.

That should be DB_Dance xD

You dont need that other variable. Dance to AnimBP

you can delete that variable and any code that uses it

sorry I got confused on which variable was which there.

[eternal ivy]

did i tangle this?

[trim matrix]

that looks perfect

although

[eternal ivy]

thanks so much, I'll give it a shot!

[trim matrix]

Like i was just saying, you can get rid of the Dance to Anim BP

you dont need it

delete that part

[eternal ivy]

ok great

[trim matrix]

let me know if its working for you

[eternal ivy]

T.T It's working!!

[trim matrix]

perfect

so yea.

the rule is basicly

After you construct a widget

promote it to a variable

So then that you can pull data from it later on

If you dont promote it to a varialbe, you will never be able to access that widget again

and it will continue existing in the game foverer and ever xD

[eternal ivy]

thanks a lot! Now it should be easy repeat this for all the other anim states.

[trim matrix]

Which also isnt good lol

[eternal ivy]

I'll keep that in mind 😄

[trim matrix]

good luck. Also keep in mind that Animation Montages exist

If you try to make to many animations using an the AnimStates and such...

It will become a nightmare

so at some point look into ANimation Montages

[eternal ivy]

I wanted to use the controller to control blending animations base on direction

[trim matrix]

Well then yea looks like that will work out for you then

and ikr

[trim matrix]

Theres a million things just on youtube about learning BP basics that revolve around that

I swear if you just search learn unreal bp you will find something usefull xD

so true tho lol

[twin ibex]

Thanks, that's what I was looking for. I reallllly don't wanna learn any bad practices this early on

Do you know of any youtube people or courses that show good and efficient processes of learning?

[trim matrix]

Learning about object oriented programming in general will help a lot as well. I feel like many tutorials around Unreal BP don't touch on the fundamental ideas behind it. Not understanding how it works is a sure fire way to lead yourself down into bad practice territory I believe.

Its been to long I cant remember anybody specificly

yea in the end its pretty much just a visualised form of line to line programming.

[twin ibex]

Yeah, I figured it would be something like Scratch, just a more visual programming language

[trim matrix]

well its alot more then that.

[twin ibex]

Yeah I found that out the hard way lmao

[trim matrix]

lol yea xD

[twin ibex]

Thanks for the help guys, I'll come back and ask for help if anything comes up that I can't figure out

[trim matrix]

Good luck!

[sacred estuary]

just wondering if anyone knows if there's a way to stop drawing a line trace after it's hit something? right now the line trace continues to its end even when it hits an object

[trim matrix]

Pretty sure the built in functionality for drawing a line trace is simply for simple debug purposes only. So not like theres a bunch of config options as those arnt needed for simple debugging. I dont think you can.

[quartz pawn]

hey anyone know how to make a good loading screen without a delay? like I want it to actually load the level up

[odd ember]

you need cpp for true loading screens

[quartz pawn]

why

[odd ember]

because

I don't make the rules

that's just how it is

[quartz pawn]

but theres goot be a blueprint way

[odd ember]

nope

you can fake it in BP

[quartz pawn]

plugin?

[odd ember]

but a real loading screen requires cpp

I dunno, there might be a plugin somewhere

I don't keep tabs

[quartz pawn]

i found one, is there a way to use a UE4.27 plugin for UE5

[odd ember]

no idea, I'm not on UE5

you can try

[meager spade]

Am I dumb or does the source angle on a directional light do next to nothing?

[calm willow]

So... i have a noob question 🙂
I'm transitioning slowly from unity, I am wondering how generic referencing works in BP, for example i have a BP that needs has an OnOverlapBegin event, however the collider in question is temporary, i don't want to go and redo the noodles later (ideally), so i would like such event to be on a variable collider (which is possible), however i can't assign the value of such collider to be an actor from the current BP.
What's the correct way to do this?

[quartz pawn]

anyone know how to take a UE4 plugin to UE5

[timid flint]

Is there no way to instantiate an object from a blueprint class in a construction script? spawn actor is not available there

[midnight ravine]

When travelling this error pops up. It only pops up when a client is connected however.

I'm not trying to travel to ThirdPersonExampleMap though.

[faint pasture]

Is that map set as the loading screen map or whatever it's called?

[midnight ravine]

The map I'm trying to travel to is 1

nah just a regular map.

[faint pasture]

Check your maps and modes tab of the project settings

[faint pasture]

There should be more there. Also, try doing the open with a console command and see if it does the same thing.

[midnight ravine]

huh

I just put some map into both fields and now this error doesn't show up anymore. Weird.

Thanks.

[faint pasture]

The client is probably not getting the travel and defaulting to default map which is nothing so maybe it tried to go to the last good default map which is deleted.

Does the client follow when server opens map 1?

[midnight ravine]

nah

There's no BP equivalent for this, right?

[somber fulcrum]

Hello All, newbie to BP and first time asking a question here, so if my logic doesn't make any sense please let me know. I have a third person camera and I'm manipulating the FOV value depending on if the player is aiming down sights, or speed boosting. I figure if the triggering of one is conditional on the other, then that means no conflict in the camera FOV. this almost works, but there is visible snapping when I release the boost button and press the aim button, & vice versa. Any ideas on what I can do to solve this??

[quartz pawn]

can anyone help me make a UE4 plugin work with a UE5 one

[calm willow]

save current fov, your calculated fov is the "target" you want to get to, lerp between current and "target" fov (by lerping, eventually current = target)

[quartz pawn]

i added my plugin to the plugins folder and it isn't showing up for me to enable?

[somber fulcrum]

that makes sense, but I'm not sure how to go about saving the current fov value

[calm willow]

create a variable, call it "currentfov", default it to the default fov, before going into Set field of view (after lerping) set it to the current fov you've calculated (the lerped value)

[quartz pawn]

anyone?

[somber fulcrum]

aaah okay, I was guessing that was what you meant. Thanks! I'll give it a shot....

[lyric holly]

How do you get a reference to an audio component? In the level bp i can simply select the audio actor and then right click in the blueprint and get it..

[quartz pawn]

how can you return something for a custom event? like I am doing this in my game instance and want to return a value

[burnt saffron]

Why wheni call attach actor to actor its transform changed?

[calm willow]

you probably want a function and not a custom event, the BP component return value should help tho

[quartz pawn]

alr, another quick question, my widget UI isn't showing on the client but is on the server (listening server btw). do you know how I can fix that?

[velvet dagger]

Bah,"Conflicted with K2_Node_Event_7 and was replaced as a Custom Event!"

Dunno what's happening

[tepid cipher]

Poor naming conventions.

Every custom event I add "CE_" before, functions I add "F_" macros "MAC_" .etc, I do this so I can identify easier, if I want to list my custom events I just search ce_ and easy.```

Had to code bracket because of the underscores messing with the sentence

[velvet dagger]

Lol :)

What's weird is that when I renamed it some gibberish and put it in the original name it worked

[tepid cipher]

people have a tendency to have "Add_Health" as a custom event and function and when you're trying to run the function it can be a nightmare, especially for multiplayer

[velvet dagger]

Oh jeez

[tepid cipher]

I got my coder mate on to that, when he was converting stuff to c++ and didn't adhere to the naming conventions and then created a bunch of chaos

[velvet dagger]

So I should rename it something else shouldn't I? :']

[tepid cipher]

imagine adding health and needing the custom event only to find it's running through a function that's not replicated

[velvet dagger]

Probably not good bro

[timid flint]

I have a scene component I add children to in Construction script, but in my BeginPlay they are in different order. Is this the intended behaviour?

[tepid cipher]

use my naming conventions, convert everything to it, avoid confusion

[velvet dagger]

Alrighty :)

I made a take damage event and didn't get an error, should I change the name?

[tepid cipher]

I would

[velvet dagger]

Alright alright

Thank you :)

[tepid cipher]

you have in gamemode start game and stop game

imagine if you wanted to create your own start game and you are using these terrible inbuilt engine ones

[tepid cipher]

beginplay only runs when you run the game, constructionscript is when the bp is created/updated/compiled

so the construction script is always going to run 'first'

[velvet dagger]

lol im getting warnings again :'p

[timid flint]

yes, but why are they in different order? in the construction script, after adding all the children to the scene component, I try to get the first child and it's correct. but then if I get the first child in BeginPlay it's the last one

[tepid cipher]

yeah something ain't right there

[velvet dagger]

I'm using an interface blueprint

I've literally put in pure gibberish and got the error

It's crazy :'|

[tepid cipher]

@velvet daggersometimes, UE4 bugs out and needs to be reloaded

[velvet dagger]

So you think I should restart it?

[tepid cipher]

I would

[velvet dagger]

Alrighty : )

Thanks for the help!

[tepid cipher]

it's ok

[tepid cipher]

hmm what are you trying to do? why do you need to get all children of a scene component?

[timid flint]

I generate tiles for my chessboard and have them all inside a scene component to group them and then reference them by index. Here I set the first child to invisible in construction script and then spawned an actor in BeginPlay at the first child (could not spawn actor in construction script)

[tepid cipher]

@timid flint Why wouldn't you use a blueprint for the square with details on it, and just spawn them in an array?

from memory I avoid scene components like the plague

a 2D array would serve you better from my understanding

[timid flint]

I thought there are no 2d arrays in unreal

at least in blueprints

[tepid cipher]

I would get creative

so through the power of structs, if you have used them you would do this

https://answers.unrealengine.com/questions/180534/two-dimensional-array.html

and vector 2D arrays as well someone said in the comments

but with a 2D array you would just be able to use the array position to move pieces, which would be simpler

[trim matrix]

You can also just use a single array and use some simple math to make it work.
Index = 0-7 is row one
Index = 8-15 is row two
That kind of thing

[tepid cipher]

that's true

[trim matrix]

I remember making a grid system like that once.

[tepid cipher]

you couldn't use that for moving pieces I wouldn't think

[timid flint]

that's what I do, but instead of having an array variable, I used a scene component. trying with variable now

[tepid cipher]

you could use 2 byte variables for positions of x and y

[trim matrix]

Why not with moving pieces?

[tepid cipher]

my smooth brain wouldn't math the move from 0,8 (0,0) to 3,11

[tepid cipher]

in a struct you want 2 byte variables, and a blueprint for your square then just make that into an array

[timid flint]

when I create an array of static mesh components, the editor crashes...

[tepid cipher]

that's what I'd do anyway, because i'm lazy

[trim matrix]

lol idk what you mean

(0.0) is index one

(0.1) is index two

each index is one grid space

[timid flint]

it's just y * sx + x. to store in 1d array. that's not my problem

[trim matrix]

nice then

[tepid cipher]

oh i mis read what you were talking about, I thought you meant x as 0-7 and y as 8-15

[timid flint]

it's kinda strange ue doesn't have a grid system implemented though. Or maybe I just missed it

[trim matrix]

nah it doesnt have one

Not really

Though there is paper 2d tilemaps

[tepid cipher]

you gotta make it yourself, much like a lot of things

[trim matrix]

and it sounds like to me...

your creating each square seperatly right?

each square is its own mesh?

[timid flint]

yes. I'd like to be able to change material on hover etc.

[trim matrix]

well tbh thats not nessicarly a good way todo grids

[tepid cipher]

you peaked my interest with this chess thing

[trim matrix]

Making each square its own mesh

[tepid cipher]

let me whip something up

[timid flint]

I thought I'd work with a single mesh and sockets, but it seems a bit complicated to generate them on the fly

[trim matrix]

A pretty good way I found todo grids, is to use a Paper 2D tilemap as the background. Then have create an array that only holds gameplay objects using this 1d grid and math thing.

[timid flint]

and then I'd need custom material with logic for hover

[trim matrix]

This way you wouldnt be generating the grid at all

The whole grid would be handled by the Paper 2d Tilemap

all you would be doing is just filling in which objects are in what spot using your array/

but thats a different direction then the one your heading

so only if you want to change courses a bit

[timid flint]

I tried playing with tilemaps. I think I had trouble manipulating the tiles after the creation

[trim matrix]

its a bit tricky since the variables are in the worst locations omg

Took me forever to figure out how.

Also things like,

Changine the material as you hover over the square..

you can just have one square thats moves as you move your cursor around

It can just snap to above whatever grid your cursor is currently over.

So for that instance you wouldnt be changing the tilemap at all

[timid flint]

hmm. and how does snapping work?

[trim matrix]

well you just program it in using a simple script on the MovingSquare actors event tick

Like EventTick -> GetGridCordUnderCursor -> GetCenterVectorOfGridCord -> SetActorLocation

along those lines

anyways again im just proposing a different solution then the one your going down. Up to you if you want to switch gears and go that way.

[timid flint]

ok, I might look into it if I have more troubles or when optimising for performance. for now, since it's just 64 squares, I don't think it'll be too heavy

[trim matrix]

Alright. If your generating them how you are rn. Then its prob just a random bug in the code somewhere

And try generating it during runtime

It sounds like your doing it during editor construction rn and not runtime?

Maybe a begin play would work better.

[timid flint]

yes, so it's visible in the editor

[trim matrix]

yea thats fine then if you want it to be visable. But it might be worth to scrap it and regenerate it during runtime as well.

Just make sure your system can handle that lol

[timid flint]

so, it worked when storing the components in an array. I'd qualify the inconsistent ordering in construction script as a bug

[trim matrix]

well just try not to use editor construction script for things that effect gameplay.

it has lots of wierdness

[timid flint]

oh, I remember another issue I had with the tilemap was flickering edges when panning in 3d

[trim matrix]

oh fun

well tbh the tilemap part can be replaced with any image

it could just a plane with an image on it

or for 3d

a generated mesh

you know

[timid flint]

I need to be able to generate it, so it could work with other variants like 4 player chess etc.

[trim matrix]

yea

[tepid cipher]

I was curious

now each of those are a blueprint, that blueprint can hold details

[trim matrix]

lol rip

[tepid cipher]

what pos they are, what is on them

that's the generator, it generates the BP then throws it in a struct, that struct holds positions, now that I think of it I could just use a BP array, but this is each tile and pos so it's better I think

also I couldn't think of a spawn code so I just flipflopped the colour change, lmao

[timid flint]

I use (x % 2 + y % 2) % 2

[tepid cipher]

I use smooth brain tactics

[timid flint]

although It feels it should be simpler

[tepid cipher]

%2 might be the way to go for that but eh

flipflops!

but yeah that's pretty much all of the code anyway

if you wanted to get what's selected, you can always do an linetrace to the blueprint and setup a selected blueprint in your player controller I think it would go

[timid flint]

another strange behaviour: if I play start when I'm in the event graph of my blueprint in the second window, the game starts normally at the level viewport. when I dock the blueprint editor as a tab and press play, it begin at blueprints origin (in both scenarios, if I press play at the level viewport it start normally)

[tepid cipher]

that sounds like how things are generating on screen

[timid flint]

if I could only disable the always on top feature..

[velvet dagger]

Would I be interrupting if I asked for help again? lol :'>

[trim matrix]

no lol

[velvet dagger]

g o Of

g o OD

(is this even possible?) I want a sound clip to start at the beginning, loop a certain part, then continue playing normally after a certain amount of time. How would I go about doing this?

[tepid cipher]

nah you got a few of us here

[trim matrix]

Not sure tbh i dont touch audio anything lol

[velvet dagger]

Awww

[trim matrix]

but 10000% possible

[tepid cipher]

@velvet daggerwell UE4 doesn't have a good audio engine, I found this out when I was creating my own "Banjo kazooie" style sound system

which I still have to implement for a client

because it's engine is basically a fetus, you have to create one

[velvet dagger]

Oh man

[tepid cipher]

good luck 👍

[velvet dagger]

I'm fairly new so uhHh

Gah dang

[trim matrix]

Then prob just dont think of it as possible xD

[tepid cipher]

I recommend creating like a sound master or a conductor blueprint, put that in the level and have it control everything

[velvet dagger]

I could just make different sound clips for the beginning, loop, and end

I get really worried would I have new things mentioned to me

I'll be doing this and that and there's MOST LIKELY a wayyy easier way

Makes me die

[tepid cipher]

I know I had to create my own sound player, with start/stop and what not, you have to actually reference a sound to gain it's controls, you can't just load a sound in and start/stop/play it or do speed things, it's a bloody nightmare

[tepid cipher]

welcome to game dev

[velvet dagger]

I think to myself that someday someone would look through my "code" and make fun of me

Understandable

[trim matrix]

Its gonna be you xD

in like a year

thats how it works lol

[tepid cipher]

i know I created a chessboard in about 10 minutes, efficient enough, while people struggle for days, not to toot my own horn but that's just experience and game dev in general, even I find easier ways to do things, but it's more "Oh, you're telling me I spent 3 days/60 hours only to find out garbage collection for UI's don't exist really?"

[velvet dagger]

Well, I gotta start somewhere and waist hours of my life to become a developer :')

[tepid cipher]

just do what I do, and always code badly

[velvet dagger]

Haha nobody will know until the game breaks B)

[trim matrix]

[tepid cipher]

unless it's polished code, and it works, and can be modular, and taken out with ease, then it doesn't matter

[velvet dagger]

I'm making my first prototype so I haven't been caring about that

[tepid cipher]

modulate everything

[velvet dagger]

I planned on making a prototype really sloppily, then rebuilding everything I've done

[tepid cipher]

that's called, causing your future self pain

[trim matrix]

bruh

[velvet dagger]

So it's a bad idea? :' D

[trim matrix]

I dont think he would even know how to write polished code

[tepid cipher]

https://tenor.com/view/oogway-my-time-has-come-gif-8019684

[trim matrix]

no your fine

this guy talking to you like you been coding for years

lol he just said hes new

[tepid cipher]

it's ok

[velvet dagger]

E c k

[tepid cipher]

it's why I said, it doesn't matter because you always find more efficient ways to do things

[trim matrix]

thats an amazing idea

[tepid cipher]

just look forward on learning time saving ways

and then realize pain

[velvet dagger]

For real or are you joking? xd

[trim matrix]

for real

If your trying to learn dont stress about it

writing amazing code

[velvet dagger]

Thankkk youuu

[trim matrix]

it will cause you more pain if you try and write amazing code while your learning

[tepid cipher]

@velvet daggerit's fine, prototypes are messy, and if you're learning that's what I did till i could rebuild, or throw the project away

I know i've remade projects

they turned out better because I can dump my experience in them

not just coding but gameplay too

then I realize my ideas were bad

[velvet dagger]

This is all UI elements built into the default 3rd Person Character in that template, just wanted to show that lmao :}

[trim matrix]

since if you spend 20 hours trying to make an super modular crazy system, while your still leanring basics. Then 20 hours later you will have learned new technique and all that 20 hours you spent was worthless.

[velvet dagger]

Besides the stuff on the right that's shooting and crap

[trim matrix]

lol we all been there xD

tangled mess

[velvet dagger]

My sister told me some people call it spaghetti coding or something

[trim matrix]

mhm xD

[tepid cipher]

oh

let me show you something to make you feel better

@velvet dagger

[faint pasture]

Does this pass the sniff test for the Gameplay/MenuUI control transition?

[tepid cipher]

sometimes mummas ravioli is unavoidable

[velvet dagger]

Spaghetti on fancy plates

[faint pasture]

Bruh......

[trim matrix]

ikr

[timid flint]

I like to think there are 3 major versions in every project. The first one is a mess of a spaghetti that just barely works, but it does the job, although it's not modular. Then you need more features and you refactor almost everything which gives you the features, but end up with a ton of bugs. The third version is optimisation and bug fixing of version 2.

[tight schooner]

There's a get axis node iirc

[tepid cipher]

can't condense it because of free look

[trim matrix]

Something called functions or even colapse nodes

[faint pasture]

Get Axis Value

[velvet dagger]

What does modular even mean?

[trim matrix]

lol dw

[tepid cipher]

I like to have my insides hanging out tyvm

[faint pasture]

Once you know what you're doing you can make BP very easily readable.

[tepid cipher]

or when you've finished it you can section it off into a hazard zone

[trim matrix]

make things straight

and use comments

and give nodes proper space

[velvet dagger]

Satisfying

How long have you been coding for?

[faint pasture]

Wait till you see my BP Pacejka tire model

[trim matrix]

Well prob like 5 years

[velvet dagger]

Ohhh I have a question about online gaming

So

I also planned on making everything for my character, and once I'm finished add the online elements and stuff to it. Is that an ok ideaaa?

[trim matrix]

Oof well.

Online is an entire other can of worms

[faint pasture]

Start from Day 1 testing in multiplayer

but if you have to ask

[tepid cipher]

expandable code, or code that you can remove and it doesn't break everything, when you leveled up enough, that's all how you code, another project i'm on we did this from the get go, added like a year or 2 of development but, made the transition to C++ a breeze, made it so when we polish the code everything just works

[faint pasture]

don't do multiplayer for your first attempt

[trim matrix]

yea xD

Its litteraly like 3x complicated

and more to

[velvet dagger]

YouTube tutorials shall pave my way B>

[tepid cipher]

No pretty colours?

[velvet dagger]

Probably a bad idea

[trim matrix]

yea you gotta seriously take some time out and learn it

no colors are distracting

[faint pasture]

No, fuck that. Youtube enough to learn what the classes do and general concepts then do it yourself

[trim matrix]

makes it less readable

[faint pasture]

following tutorials will lead you astray IMO

[trim matrix]

xD

mhm

[velvet dagger]

Oh god

Well

Uh

That's what I've been doing for the most part 😔

BUT

I've learned a lot

[faint pasture]

Make sure you know all of this
https://youtu.be/QcXHEsR0xHI

[velvet dagger]

Yeah I really need that

I was confused when some guy started talking about classes

[faint pasture]

Then watch some of the Wadstein WTF is series for specific functions

and just make something TINY and complete. Like super tiny, like Brick Breaker

[tepid cipher]

@velvet dagger so multiplayer, is building the single player with "replication", replication is it's own thing http://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf multiplayer must be implemented from the ground up in design and code, or you shall feel great pain.

[timid flint]

since we're on the topic, I had trouble organising stuff myself, so https://ue4.style

[faint pasture]

The great thing about UE4 networking is that if you do it right, your project should work just fine in single or multiplayer.

[atomic lake]

If there is a possibility that your project might need multiplayer features at any time, you should build all of your gameplay with multiplayer in mind from the start of the project.
https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Networking/Overview/

[trim matrix]

yea

[faint pasture]

Honestly if you're new don't even think about multiplayer, or you'll spend a year making something that doesnt even work

[trim matrix]

[velvet dagger]

Dang man

Wanted to make a shooter lmao

That's what I've been working on too x d

[timid flint]

that's why I've gone with chess for my first game. Only a bit more complex than tic-tac-toe xd

[trim matrix]

multiplayer hard

not ez wins

[tepid cipher]

run custom events, have server client in mind, replicate everything and test as you go, forget to replicate something? then it's going to cause desync issues out the wazoo

[velvet dagger]

Yeah it's a mess

[faint pasture]

Don't quite replicate everything, just replicate what's needed.

[tepid cipher]

everything that's needed*

[trim matrix]

[velvet dagger]

Lmao

I'm gonna be struggling for a while 😅

[tepid cipher]

fun story, because this other project we didn't design multiplayer correctly, it cost us a years worth of dev time

[trim matrix]

lol it will be ok as long as not multiplayer xD

[faint pasture]

I started off with zero experience and jumped into multiplayer from Day 1. 7 years later and I have 4-5 unfinished projects in various states of playability.

[tepid cipher]

well you past the test of all of us hounding you, and bombing you with information, you'll be ok

[velvet dagger]

You serious?

[faint pasture]

Make something small and complete it. Everything from main menu to win condition to game exit.

[tepid cipher]

it's how I speed learned on how important design was with multiplayer + UE4

[velvet dagger]

Alright alright

Is it ok if I work with 3D tho lol?

[trim matrix]

yea

2d honestly less obvious with unreal

alota wierd things with it

3d just makes sense tho

[velvet dagger]

I'd just use Gamemaker instead

I've used it before

[tepid cipher]

after you complete projects for your confidence, filling your head with little victories, then you might have the resilience to deal with multiplayer

[velvet dagger]

Kinda gave up

[trim matrix]

rip

[velvet dagger]

Lmao

[tepid cipher]

i was a monogame/xna dev before unreal

[velvet dagger]

I appreciate everything you guys are telling me :)

[trim matrix]

gl

[velvet dagger]

I'm gonna need it

[faint pasture]

When I say something small, i mean like this small.
https://www.youtube.com/watch?v=1O05fOBfUGM

I never even finished this tho lmao

[tepid cipher]

i was lucky enough to be tutored and bought up to speed with UDK/UE4 and everything game related, then 5/6 years after of game dev everyday I still feel like a scam.

[trim matrix]

nah its ez wins just throw your head at the wall till it works

no luck needed

[tepid cipher]

luck isn't going to help, motivation will

luck is a scam

[trim matrix]

lol scam

[velvet dagger]

Sometimes I just slap things together and surprisingly (more like hopefully) it works

[velvet dagger]

Pretty much this right?

[trim matrix]

yup

[velvet dagger]

Unreal in a nutshell I guess :)

[tepid cipher]

especially when you have fun on why your UI isn't working, you only created it once, then learn that garbage collection for widget is garbage

[velvet dagger]

Making UI is where I have the absolute most fun

[trim matrix]

Ikr

[velvet dagger]

I love making little animations

[trim matrix]

So fun

oh lol xD actualy?

[velvet dagger]

Yes :)

[trim matrix]

the animations are fun tnh

tbh*

[tepid cipher]

I am envious, I been doing UI efficiency stuff for a year

[trim matrix]

widget hurt me tho

[velvet dagger]

Fr

[tepid cipher]

I hate everything UI

[trim matrix]

so tedious to setup

ikr

[tepid cipher]

I hate widgets

I hate the fact there's no child parent

[trim matrix]

xD yea

[tepid cipher]

i hate the fact they run like dogballs

i hate everything about them

[velvet dagger]

Trueee, but I really love designing things to be arranged really nice, my coding surely doesn't show that though

[trim matrix]

well you can use children with widget, they just wont keep the Widget elements

[velvet dagger]

I'm new to UI so I most likely don't understand your guy's hatred yet

Like

I don't even know how to make a popup

[tepid cipher]

i hate the fact if you destroy a widget and it's not referenced, it still acts as if it's referenced because you needed to recreate it but it grabbed the one pending delete from the garbage collection, so you have to ass about on why the hell your UI isn't working at all or updating.

[trim matrix]

just dont do widget

my fav thing todo

[tepid cipher]

lol

[trim matrix]

leave that till i have to

then sad for awhile

[velvet dagger]

Are there other methods besides widget?

[tepid cipher]

a texture on a 2d panel and have it 3d?

[trim matrix]

not really anthing ue4 has built in for ui

other then widget

not like some other ui system

[velvet dagger]

I was asking cuz of this l o L

[trim matrix]

oh lol xD

[tepid cipher]

paper 2d was a bit of a nightmare too

[trim matrix]

well I meant i just focus on other things most of the time

[velvet dagger]

Ohhh

[trim matrix]

then slap the widget together and call it good

[tepid cipher]

don't get me wrong, I am now a widget master

[trim matrix]

not fun

[velvet dagger]

Whenever I can't get something done I just go and make some UI details and animations

[tepid cipher]

the pain to learn things is what builds your skill

[trim matrix]

You enjoy ui more then programing game stuff?

[velvet dagger]

Yeahhh :)

[trim matrix]

nice

[velvet dagger]

Not gonna help me when I need to program tho 😓

[trim matrix]

they should just make ai that program our game for us

pls

[velvet dagger]

I have this question that sounds SO SIMPLE but I don't know what to do : (

So

[tepid cipher]

Ask away young dev

(also made a new emote)

[timid flint]

woohoo! now just waiting for the models to be finished

[trim matrix]

[velvet dagger]

I want to make some very simple dynamic music, just 3 sound clips. I want it where that when one sound clip is playing, all the others are silent, but there's something that triggers that sound clip to fade into the other sound clip and continue from where the first clip is at. Dunno what to do

Tried my best to explain it

Not the best at explaining :")

[tepid cipher]

that's part of a conductor you need to manually setup

[trim matrix]

you would have to create some sort of music manager bp

[tepid cipher]

yeah then manually play/stop on an event tick with triggers and what not, a hellish nightmare

it's not that bad but, it feels dirty

[faint pasture]

No, event/enum driven

[velvet dagger]

So would it just be an actor orrr?

[tepid cipher]

yeah but you would have to still get the player time and if a sound is finished or close to finished

[faint pasture]

We have dynamic music just driven by a Intensity parameter but that's a different approach

[faint pasture]

You have to learn how the audio system works before pulling this off. Start digging into mixes and concurrancy and cues and all that

[trim matrix]

yea

[tepid cipher]

yeah a BP actor, call it a conductor that's persistent in your level

[faint pasture]

But don't get too scatterbrained, pick one thing you want to learn and learn it for a few weeks, doing whatever it is in your game you want that uses it.

[velvet dagger]

I've dealt with concurrency a bit, I think I'm good with cues

[tepid cipher]

an intensity controlled audio is different from a continuous one too, haha

[faint pasture]

Well it is continuous and synced, just the mix changes based on intensity

[velvet dagger]

Wish I could just hire people but I'm broke x d

OOps

[tepid cipher]

that's no fun

[velvet dagger]

I guess so!

[trim matrix]

yea lol no fun

that cheating

[faint pasture]

I mean if I won the lottery I'd go on a hiring spree, but I haven't, so I wear all the hats.

[trim matrix]

xD well yea

[tepid cipher]

without pain and learning, you won't understand the suffering

[velvet dagger]

That's what I want to do, so it's like, while you're waiting the music is low, in combat the music increases, then once you're done the low music plays again. Is that what that is?

Oops forgot the reply

[velvet dagger]

a

There B)

[faint pasture]

Yeah we did that by a cue with each track driven by an intensity parameter

[velvet dagger]

Would I make each track a different cue or all in one?

[tepid cipher]

Going to reply to my issue if anyone else has had it

it's been a nightmare to dev with this issue

[velvet dagger]

Got a gamer setup

[trim matrix]

i remeber having issues like that

[tepid cipher]

if it's only 3 tracks, you can make 3 functions that have stop all music and play their own, with a fade system, I never finished my audio thing, it was rubbish anyway.

[trim matrix]

resolved itself tho since hasnt happened in forever

[tepid cipher]

the pin dragging thing really annoys me

i was wondering if my monitor is dying, it has gsync and it looks like gsync is failing or something

[trim matrix]

is it just that version of ue4 or something

[tepid cipher]

i didn't have it before i formatted my PC

[faint pasture]

This is our approach

[trim matrix]

idk then

[velvet dagger]

That seems super cool :)

I'm gonna go try that out right now

[faint pasture]

We use 3 layers of intensity and a low hp/danger track (the 4th one)

[velvet dagger]

The thing is though, I don't want the previous and current track playing at the same time

[faint pasture]

just change how the math works. I think setting mix volume to 0 pauses the track, thats why our min is 0.01

so you'd have track1 at 1.0 volume, when the thing happens, fade it to 0 and fade in track2, then reverse that when the thing un-happens

[velvet dagger]

Thank youuu

I'm gonna go test this stuff out

Sorry if you did that in the video, I didn't watch the full thing x ddd

[fiery swallow]

they should always start the conversation off with hello

[trim matrix]

well within each componet, you just need to get a reference to the other componet. If you need just a simple way todo that, you can use GetOwner which returns a actor reference to the actor which owns the componet. Then use that actor reference to find the other componet

[fiery swallow]

jokes aside what do you mean? They are in the same actor so all you need to do is drag the reference onto the blueprint board

[trim matrix]

another way,

On each componet, create a variable that holds a reference to the other componet.

Then on begin play in your actor

get each componet and set its reference variable to the other componet.

[fiery swallow]

they already have references to eachother... they're in the same actor

[trim matrix]

hes talking about from within each componet it sounds like

not on the actor itself

[tepid cipher]

Your reply was better than what I could come up with.

[timid flint]

Is there an easy to way to only fly with wasd with a mouse button pressed, like in the editor? I tried hiding/showing cursor on mouse button press/release, but it behaves strangely

[tepid cipher]

make a boolean that is "flymode" and have that toggle

if a flymode == true then you can fly around, have it on when you press a key

you would probably want to turn it into a function called 'F_FlymodeCheck"

then just run that on your keys since it's repeating

[timid flint]

I guess the answer is "no" 😅

[tepid cipher]

it's easy enough, it's a boolean in a nutshell

much like jumping or is in air for animations

[timid flint]

I thought it would be an existing option or something

since it's there for the editor

[tepid cipher]

nah i don't believe so

it's for your chess game right?

[timid flint]

yy

[tepid cipher]

yeah i know what you're talking about but that's all controls you gotta do

[timid flint]

I want the mouse to click on things, but it's nice to be able to fly around

[tepid cipher]

yeah just a boolean to enable what you want will do

[timid flint]

exactly like in the editor

[grave relic]

Anyone that can help me with some reference stuff? Im spawning an actor, in that actor i have a reference that is "my spawn point" the spawn point is a separate actor. I need that "my spawn point" reference to be set when the actor spawns

@grave relic

[quick summit]

Hi guys,
I have a very simple question:

On my screens in my set i have a color-bar placeholder texture which later gets replaced by live video. However whenever baling lights the placeholder gets baked into the reflection captures. I figured out turning the screen material to black makes it look better in the captured reflections but i want to keep the placeholder in editor for visualisation..
Is there a way to make the editor automatically replace the texture just when baking?

[fathom spindle]

Hi all, does anyone know if its possible to make an actor blueprint that just makes a realtime copy of the skeletal mesh component of a pawn? i'm trying to crossfade between two materials with different blending modes on a character and the only way i can think is to have a copy or copies of the mesh with the same animation to fade in/out over the top like so:

[fathom spindle]

put more simply i guess is there a way to have a skeletal mesh actor that simply recieves and mirrors all the bone transforms of the mesh thats driven by the game logic?

[half crypt]

make it an AI

[fathom spindle]

hi @half crypt do you mean all the stuff with behviour trees and stuff?

my logic is pretty simple

[half crypt]

yh, it should not be that complicated

[fathom spindle]

i see ok

was just attempting to script something

[half crypt]

airt

[fathom spindle]

like a for each loop to get all the socket transforms from my main BP and set them on my instance

[half crypt]

hun?

[fathom spindle]

i dont know what you mean

is that not possible?

[half crypt]

if am correct you want a character than can replicate every movement of the player?

[fathom spindle]

yeah so i have a skeletal mesh that has some simple ai and animations, plus a ragdoll death sequence, and I want to create a copy of it that can exist in the same space so i can layer translucent and opaque materials for a dissolve transition

this works

sort of

using a posable mesh instead of skeletal

[half crypt]

what about actions?

[fathom spindle]

it seems to follow the animation and the ragdoll

thats all i need

[half crypt]

i've got another idea

just try that

[half crypt]

that will be on the actor that replicates the player movement

then this will be on the player character

[half crypt]

does this help?

[fathom spindle]

ah yeah its ok though because this character isnt moving

but yeah that would be important if i expanded it

[half crypt]

you can also do the same for the move right event

[half crypt]

????

[fathom spindle]

im not worried about player input and movement

i dont have that

just working on an effect atm

[chilly jetty]

Hi there, sorry to bother anyone but I have a question

is there a way for me to set the value of a custom depth material value I am using to change the custom depth value of an actor for them to match certain mats?

I have the actor

I want to know how to set the value for the texture

[manic wigeon]

hi guys, i have an issue seems like my main menu ruined the whole circuit of the arc viz (game). in the main menu my cursor is not showing. also the buttons all seemed to stopped working and if they sometimes do work its not letting me move or turn my mouse but just shows the spawn view of the character

can anyone help me

and when i open the main menu the cursor seems to not show anymore

which is wierd because mouse cursor is still on

i had previously changed location of the main menu widget node from the main menu to the fps character bp instead as someone recommended it for a cleaner workflow but i am not sure how i can retarget all the on clicked from the main menu bp to be called in the character bp

[grand hawk]

Here is two actors. The one is a raft which is simulating physics and another one is a paddle to control the raft but, it doesn't simulating physics. Let me attach the paddle to the raft as childactor. Then, here is the problem. The raft is launched like rocket. It looks some physics error occurred by overlapping with paddle. And I've found there is a function called 'IgnoreActorWhenMoving' which ignore all collision each other. So i used the function like the picture and it doesn't work. What am i did wrong?

The function AttachActorToComponent's parameter 'Weld Simulated Bodies' working only on actor whose root component is PrimitiveComponent. Could this be the same problem?

[wise remnant]

Hi could anyone help me with how I could go about changing a value pulled from a weather BP i.e "March" and then taking that into some kind of array and outputting a new value based on that? i.e "Jan, Feb, March" from the weather plugin could be called just "Spring" for example.

[inner blade]

@wise remnant An easy way to do this is have each month of the year be an integer. So 1-12, then just specify the month ranges for each season. So if month integer is equal to 12 for example you are in Winter.

@manic wigeon Err.. I don't know who recommended that, but putting the widget on beginplay of the character is a little odd. Judging the style of the widget, that menu should likely be opened from the map blueprint of the map you load into for the main menu. There's no real reason for the character to care about that menu.

[wise remnant]

Awesome I thought as much but wasn’t sure, thanks so much for the help 🙂

Guys, how could I detect with a capsule colider that a sword enters me, for example, a weapon mesh?

[opaque blade]

multiple ways

• attach a collider to the swords actor and setup overlaps (trigger once it overlaps); disadvantage, only triggers once on enter
• actually do a capsule trace on current sword transform; can actually handle multi-hits easily
  • do capsule trace from last to current position to trace interpositions

hey guys!, I have a BP for zooming the camera on right click. however I also have a depth of field and thats not adjusting to the zoom, any ideas how to do that? here is my BP as it is (first person character event graph)

in the timeline node I have added a float track that controls the camera, but its rather new to me so I have the feeling it should be the same for depth of field i just dont know how to implement it ..

[opaque blade]

problem is that FoV does not change the camera location while DoF is position dependant

You would need to recalculate your DoF distance based on your FoV, easiest would be to try

fovScale = CurrentFoV / DefaultFoV;
dofdistance = DefaultDoFDistance X fovScale;

*X = divide or multiply iam not sure 

[little flame]

hey @sour slate! thanks for the quick reply! however I am not sure how that would look in blueprint? im really not program strong and especially not C++....

[languid lion]

Is it possible to attach a static mesh to another static mesh's socket inside an actor?

or can it only be done in the world editor

[opaque blade]

in Component Tree when the static mesh with socket is the parent of the new Static Mesh Component there is a "Socket Name" in the details, where you can input the socket and it is attached to it

[languid lion]

It just stays greyed out and I can't type anything there

I do have a socket and I was able to attach to it in the world editor

[opaque blade]

nothing specific to C++ there actually,

but you would have to wire up some logic in BP, a get the default FoV (at begin play maybe? depending on game and your other logic), the currentfov you just set it - so divide those

and to set the DoF Distance it is actually inside the postprocessing settings iirc - so that is painful to do in BP, but you can do it I believe in you 🙂

( Get Camera, Set DoF )

[opaque blade]

even when clicking the Spyglass it does not open a list?

Other than that, you can utilize the Construction Script for it, and just attach it to the socket there

Might be a static mesh socket thing that it cannot be set in the details panel that is usually how it works for SkeletalMeshes

And I did it for normal "sockets" ie. Programmatically added ones

[languid lion]

The magnifying glass worked

I feel stupid now

[little flame]

@opaque blade thanks! I think I still dont get it though haha. I will manage, but im astonished that I dont find any tutorials since it must be a pretty ususal encounter?

[opaque blade]

I usually "zoomed" by changing the position of the camera, as it does not change FoV - which makes it also look not "normal"

[lusty elbow]

How can I draw a circle around a moving actor? I could just add a very short and thin cylinder, but there must be a much cleaner way

[little flame]

@opaque blade aha like that can you show me how?

[opaque blade]

CameraPosition' = CameraOriginalPosition + (CameraFwd * ZoomIntensity)

[open crypt]

anyone know how to remove a media texture from memory (without deleting the component, like a UMG media texture)

[earnest mango]

@open crypt I think UMG widgets get garbage collected if they're no longer referenced -- perhaps this also unloads any assets they reference?

[open crypt]

It's been awhile since I've delved into GC - how can I confirm it's physically unloaded from memory?

[earnest mango]

I think there's some kind of editor tool that lets you watch memory usage in real time, but I've never used it. Can't do much for ya r.n. besides link this doc to GG and hope it gets you in the right direction -- https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/Objects/Optimizations/

What's the default value?

[valid knoll]

Hi guys

[open crypt]

It sounds like you just have it defaulted to zero on your variable that is on your widget

@knotty knot

[valid knoll]

Can i use Game ability System without C++?

My team dont know C++, and we whant try GAS.

[dark crow]

No

[knotty knot]

@open crypt How do i check what the default value is?

[dark crow]

You would need a plugin that exposes GAS to BP if you wanna go that way

[knotty knot]

Nvm got it

@open crypt Thanks that was it

[open crypt]

if you click on the variable name, a "details panel" should be visible - scroll down you will fine it - but I highly recommend you do this video https://www.youtube.com/watch?v=EM_HYqQdToE

You will learn more in that video than you will in a single month on your own.

[chrome fog]

Why can't I have the Delay node in a function?

it's there in the Event Graph but it's not available from my custom function

[dawn gazelle]

Functions aren't latent.

[chrome fog]

how do I do something after few seconds from a function then?

[dawn gazelle]

Have your function call an event.

Could even do something like this if you want the delay defined within the function:

[chrome fog]

cool, what i'm looking for, thanks

[solar dawn]

Hi sry go budge in, what's this function used for

[dawn gazelle]

The set timer by event node?

[solar dawn]

Yeah n also the create event, look simple but what for

[dawn gazelle]

Set Timer By Event lets you have an event or function fire after a defined amount of time, and as you can see, you can also set it to loop, so it'll continually fire that event. The return value is a means of referencing the timer in question which you can then use to pause or stop the timer, or read other values about it (screenshot below).

The "Create Event" node is a means of calling a defined event, so if you have a function or event in your graph, it can call it - however, as this is an event fired by a timer, it can only be passed to functions or events that don't have any input parameters.

So if you have something you want to do say every 5 seconds, you can have this timer set up with a time of 5.0 and looping true, it'll fire the attached event every 5 seconds.

[solar dawn]

I see, so such node can also being used for cutscenes right

[dawn gazelle]

I would imagine, if blueprints are being executed in your cutscene

[solar dawn]

Hmm I'm kinda relying on BP alot that's y i thought abt it

[proud notch]

hi,

how can I make this into a function? I need to repeat this code a few times in my blue print, so I guess is better to have it as a function but timelines cannot be collapsed to functions or macros.

[dawn gazelle]

You want everything firing off the same timeline?

Timelines are sort of their own beast - they are components that control their output. If you were trying to make a function with a timeline in it, it would be like trying to use the one timeline to execute everything.

[livid vessel]

Is it possible, that get mouse position on viewport will always give out the last point, where a for example a click operation started and while performing these always choose the start point and not the current location?

[proud notch]

it is a possibility to control all with just one timeline.. but I love to have 2, one for the fade in and another one for the fade out. but if that complicates things a lot, one timeline will suffice.

[thorn fiber]

Store the initial mouse click position in a variable? Not sure I understand

[dawn gazelle]

Do you want all the things you are trying to control all at the same time though?

[livid vessel]

I do but I want a second one, which updates while draging to store a move value between them

[proud notch]

nope, things happens at different times... it is a virtual tour with teleports, so fade in and out on each teleport point.

[dawn gazelle]

So then you can't use one timeline. You'd have to use multiple.

[proud notch]

so no practical way to convert that to a function since you actually need a timeline for each event?

[dawn gazelle]

Correct

[proud notch]

😦 well.. thanks for the clarification.

[dawn gazelle]

Best you could do is maybe feed the output to a functon that can specify which object you're wanting to manipulate

But if you have overlapping events firing, then things will get messed up

[proud notch]

mm I think I leave it as is, there aren´t a lot of events/triggers in the tour anyways, I was just trying to clean up a bit my blue print.

[livid vessel]

This override will also only give me the initial location of the cursor when left clicking and draging

I found something in the forum about this problem but could not solve my problem because I dont see the pictures from everynone explaning his answer. https://forums.unrealengine.com/t/mouse-position-not-working-while-dragging-with-left-mouse-button/99266/9

Anyone know a clean way to unload a media texture cleanly? this is a window capture plugin, but I get crashes when I exit (and it doesn't have a stop/deactivate that I can find)

[soft scaffold]

Hi! I have a timeline which is controlling my projectile movement. Unfortunately the timeline stops when I shoot another one. Any idea how can I make it to works with multiple projectile shoot?

[dawn gazelle]

Your projectile itself should have its own timeline within it, rather than having it in whatever object spawned it.

[gray hare]

It's not possible to set a scene component variable to a scene component at blueprint compile time is it?

Not a TSubclass, a raw pointer to an instance. I'm guessing it's not possible, but if there was blue dark magic that made it work, that would fix my current bug.

[earnest mango]

@small quartz Yep! Have OnInteractionStart exec into a FlipFlop, where A execs into SpawnActor (and then banks the spawned horse as a var) and B execs into DestroyActor, called on that var

[small quartz]

cheers ill try it out!

[iron umbra]

I'm having an issue with Groom Assets and specifically setting their Groom Binding at runtime. It seems to function differently when "Set Groom Binding" is called then when if you just set the groom binding.

Example: Create a character BP, add a character mesh, add a groom component to it, set the groom asset, set the groom binding. It works, looks good, is bound.

Now do the same thing, but call "set Groom Binding" on begin play, with the same exact binding as was used in the editor, and the hair now appears at the middle of the character.

It's a problem because I want to be able to change the groom asset and groom binding and have it properly bound at runtime.

Any ideas?

Btw, seems to affect metahumans as well.. I tried with them.. same thing. If I set the groom and groom binding in editor, works fine, if I call "Set Groom Binding" even to the same binding, the groom moves down. Although just a bit not to the middle of the character like with mine..

Any ideas?

[odd ember]

probably order of execution

if you breakpoint it you might be able to see which gets loaded in first, and with which values

[iron umbra]

I've tried every possible combo of order of execution, including with delays etc :/. The weird thing I just noticed is, this always happens when you spawn a new groom component. Same if you use a blank groom component attached to the character mesh. BUT if you use a groom component that has a groom set, it seems to function differently.

Blank Groom - > when you set groom and then set groom binding, teleports to center of character

Groom asset set but no binding -> now when you set a groom (even an entirely different one), and then set it's groom binding, it seems to work

In theory there should be no difference between a blank groom and a groom that has a groom asset, when you set a new asset and new binding.. but I suppose not. I guess I can just set one for now and have it invisible and work around that. But still a bit weird

Or I'm just not getting it, but been on it a while 😛

Momtages, if you have a lot of anims.

And that's interpolation BTW

The Content Examples Advanced Blueprints Level has a demo of scattering static meshes but there is no minimum distance between each so they can overlap.
How would I modify this so that there was a defined minimum distance between spawned static meshes?
How would I modify the demo so I could spawn on a publicly defined target mesh or plane instead of in a circle?

[icy dragon]

My idea would give them a sphere collision so that if one overlaps with each other, it'll try relocate somewhere else.
Not exactly elegant if it goes continuously tho

[open crypt]

Similiar to what hoodieguy is saying, you can get a random point in the box, and then compare this to a range of a vector, and if it falls within the range, you loop back through the array until it is empty (make sure you have a failsafe in case the box is too small to contain everything or you will get an infinite loop

[atomic lake]

alternatively, consider using a low-discrepancy sequence to generate positions (https://en.wikipedia.org/wiki/Halton_sequence)

[jaunty solstice]

Probably a dumb way, but was thinking scattering on a grid, but randomly offsetting each by a certain amount.

[cold raft]

Is it possible to add a socket to a static mesh through blueprints? I want to join 2 bits of wood and have the nail position spawn sockets on each of the meshes to allow them to be connected

[open crypt]

as long as your random offset exceeds the size of your meshes, that should be fine

[open crypt]

You don't need to use sockets for this, just use "attach" -

But you need to try attaching the wood to the nail, that way the nail's position is used, not the wood (otherwise it will attach to the origin of the wood)

[cold raft]

Thanks for that - will give it a go

What causes the ragdoll body to move around?

[narrow kelp]

ragdolls use a bunch of colliders with constraints that simulate physics

[true valve]

So what are some of things that needs to be turned off so when in ragdoll after char's death, the body doesn't jitter?

[narrow kelp]

yeah ive been working with unreal for years and still can't answer that 🙂

best thing I've found is to tweak the colliders and constraints

let me know if you find anything useful

just disabling ragdoll mode should do

or stopping physics

What's the best way to implement attacking with weapons, and all the stats that go-along-with that?
I've watched a few tutorials, and all of them handle the shooting in the character-BP, but surely it'd be better to do it in the weapon's BP instead, to keep the various stats separate.

yea, you would catch the hotkey on the character and forward it to the weapon

Anybody know what would be the easiest (or any) way to recreate "Eagle vision" from assassin's creed?

I'm not doing exactly like it is in Assassin's Creed, but my main issue is I can't seem to find a way to make everything black and white EXCEPT certain objects which should glow a different colour. My immediate instinct was to create a post process material (which would be a glowing outline) and enable that alongside changing post-process volume settings to make everything black/white but the effect does not show any colour since the settings apply to the material as well.

I've been using unreal for a couple months, so I feel I have a solid understanding of blueprints but this has always evaded me. Is there any concepts I should look into, or is this something which might be a little out of my skill level?

Anyone heard about the issue where the details for a component declared in c++ doesn't show up in the blueprint of the actor it is attached to? Does anyone know a fix other than renaming/rebasing? (as those only temporarily fix the issue)

@rotund pilot What are the specifiers on the pointer's UPROPERTY you're storing it in?

[azure smelt]

Hey there good people, I need help with setting up this "Foot IK" for VR in blueprints. Background information is, I download this project https://github.com/kvoeten/ExampleIK I copied the blueprint nodes exactly for the "BP_PlayerPawn" and for it's Animation Blueprint and it works except for 1 feature which is the "Foot IK". In the exampleIK project when you crouch IRL so does the pawn and if you move to the side the character walks to where you moved IRL. In my game the only difference is that my character is C++ created and in the "ExampleIK" the character is purely blueprint made. Why isn't my Foot IK working?? can someone please help i've been stuck on this for days

Is it possible it has something to do with my hierarchy of components? I'd really appreciate some help.

[rotund pilot]

It's also a public field

[maiden wadi]

I'm not sure what the EditAnywhere does on that. But usually on pointers to default components, you want them BlueprintReadOnly, VisibleAnywhere. Cause you don't want to edit the pointer, but edit what the pointer points to and that UPROP is to the pointer.
