blueprint

[candid geyser]

Where

I

I just tried that and

[icy dragon]

Not as worse as UMG/Slate when it comes to the most lacklustre part of the docs

[candid geyser]

Listen stop being smart okay

[icy dragon]

But I'm not 🥲

[candid geyser]

Considering im an idiot and you know far more about this engine than I do

Im pretty sure you're smart bro

yes

I don't THINK

I K N O W

[icy dragon]

Well, I'm suck at C++ and multiplayer stuff
||and XR stuff
and ECS stuff
and mobile stuff||

[candid geyser]

That's ironic because multiplayer/networking stuff is something I know a good bit in

[icy dragon]

Anyway I gotta sleep kthxbye

[candid geyser]

NO WAIT

[candid geyser]

one more ounce of assistance pls

i beg

the "final color" node is not there

[icy dragon]

It's already midnight on the far east

[icy dragon]

Well, read the snippet description

[candid geyser]

My material what

omg i did this to myself nvm you can go sleep now

[icy dragon]

nice

[candid geyser]

Hang on hang on I think I got it

Damn ADHD

I can't help but overlook things :')

[candid geyser]

you are free from your chains, good night

Looking forward to the day where I can be the one who helps instead of the one who asks for it

[vapid ibex]

The problem of returning to the project after some time not working on it... >_<
I somehow made player push NPC Character actors out of the way when walking instead of them blocking the way, and now I need to change that either back or tone down the effect, and I don't remember how I enabled it in the first place. Any advice?

[candid geyser]

Im just brand new to C++ and UE4, im coming from a background of Lua, and JavaScript

C++ is fairly different in comparison

It's weird being part of a community that all collectively works as a team

A really good kind of weird, but definitely not what im accustomed to

I guess we are all in the same boat, after all

This came to mind because I just realized Makoto made that entire snippet literally just for me

It was uploaded only like 3 hours ago

Aka around when I needed help originally

[gentle urchin]

Its a nice platform, hopefully i can provide some basic stuff to it aswell

Even if its just for my own library/sanity

[candid geyser]

H u h ?

[gentle urchin]

Its strange for me aswell, never been part of anything like this discord server before

[gentle urchin]

The new dev pages with community snippets

[candid geyser]

Oh yeah!!

It reminds me on how things like speedrunning communities also band together, sharing new tricks and secrets and what not

It's wholesome

[last walrus]

Hello there!
I'm not sure if this chat is the correct one but are there any means to render mesh above everything including UI? (and no, making my mesh a picture is not a solution because I need to rotate and modify that mesh)

[gentle urchin]

You could have a material with a mask

Sounds like an odd setup but oh well

[last walrus]

but will this mask help rendering my mesh above UI?

(and if it will help, "weirdness" doesnt matter, any working solution will be fine)

[gentle urchin]

Not 'above' but through, yes

Or you could make your ui world spaced, but that could get tricky

[last walrus]

can you show an example? I didnt hear about that kind of masks before 🤔

[last walrus]

that will break everything I suppose 😄

[hearty barn]

does anyone know why when I launch 8 missiles some return with the delta as 0,0,0 but some have numbers like 24,180,180? they should all have 0,0,0 since the look at rotation and relative should align after rotating the actor right?

[cyan bone]

Im using WPO in material to animate my spear up and down when im walking.
Then when i face the enemy i lerp it into the horizontal position.
So what can i do for the WPO to still understand that the Z is still the spear direction?
Or this is not possible?

No. Its an instanced static mesh of a plane with the material, the spear

[sudden zephyr]

Not sure but if I see right, you're checking 2 unrelated things, you're setting world rotations but print relative rotations. I think.

[cyan bone]

in my current batallion i have 80 spears. Each batallion has 80 spears. And i intend to have many batallions.

[hearty barn]

the relative and world print out the same and they are unrelated until the set world rotation which should set the capsule rotation to the look at rotation right?

[sudden zephyr]

Oh and 'since the look at rotation and relative should align after rotating the actor right?' We don't know, we see the look at variable but we don't see how it's being set so we can't confirm if that's actually the case. 🙂

[cyan bone]

So if i rotate the instance to become horizontal. And i do what you are saying it will now animate in the horizontal. But what if my enemy is a bit to the left or to the right? I could also control that angle?

[hearty barn]

they should align yes

[sudden zephyr]

Again, we don't know, all we see is that you apply the action, not what that action actually is.
In this case, yes, you are setting a capsule's rot to whatever it is stored in lookat var but you are printing relative rot which they are not directly related and we don't know what you are doing with that look at var so all I can say now that you are checking 2 different things and that yes, you are applying world rotation to an object. 🙂

[hearty barn]

I printed with world rotation and got the same values as relative

the look at var just contains the lookAtRotation values and so this works but what I don't understand is why the difference between lookat and the roations are not all 0 as they are looking at the rotation if that makes sense

[sudden zephyr]

Huh.... Right.

Not sure, sorry. 😐

Gah, this boggle my mind too now. xD

[hearty barn]

same it makes no sense as to why these don't equal 0 but some do like ?

[sudden zephyr]

Wait, is the rot instant? Cuz in previous print, you can see 0,0,0's too. If you interp, you might getting confused with that? Also, try on a missile to missile basis and see if one by one turns to 0,0,0.

Oh, wait, is the lookat only on 1 axis/based on 1 or 2 axis?

[hearty barn]

the rot is instant rinterp just flat out wouldn't work some would flip flop between facing the target or facing opposite of it

3 axis

[sudden zephyr]

Ah, ok then.

¯_(ツ)_/¯

[candid geyser]

Okay so I ran back into the same issue I had earlier

The Snippit Lerp plugs into "Final Color" which I do not have.

Aha! Solved it!

[gentle urchin]

All this for a simple flashy widget 😁

[candid geyser]

yeah :')

[gentle urchin]

I should study those materials one day....

[candid geyser]

Im very stubborn, so im dedicated to making it work!

Im pretty sure at least-

[gentle urchin]

🤣

You got this!

[sudden zephyr]

"simple flashy widget"
Jooo... xD We need some fabulousness in our dev softwares man. xD

[candid geyser]

Come on man gimmie some c r e d i t

[gentle urchin]

I wanna see the result first

[sudden zephyr]

I'm on your side dude. 🙂 ❤️

[gentle urchin]

Then I'll give you credit

[candid geyser]

Well first I have to bring the result into this world

[sudden zephyr]

GL and do show!

Man... Now I wanna make my blender pink. Someone stop me, cuz I'm pretty sure it ain't gonna help in actual modeling. LMAO

[gentle urchin]

Rip blender

Pink of all things

Electric blue lets go

[sudden zephyr]

I mean, combo green/magenta but... yeh

[gentle urchin]

I should just turn to modeling at some point

Stop pretending to program😅

But then id need to learn that...

I made this bulky chest many moons ago

Blender uninstalled me as a user

[candid geyser]

Okay so

I can't tell what's going on

But I can tell you it's not doing it

[gentle urchin]

I wonder if my delegate and function would've solved this an hour ago

[candid geyser]

SHHHHHH

[gentle urchin]

🤪 its ok

Gpu powers are the best

[candid geyser]

Okay actually im gonna try your method

[gentle urchin]

I did a blink effect on my nuke reactors a while ago

[candid geyser]

Actually hang on imma paste it down here

During stamina use, check for the condition
Launch an event dispatcher when stamina goes below your treshold
On stamina regen
Do the opposit
A single delegate with a bool should be enough
Below treshold, true or false :)

There

instructions ready to do

[candid geyser]

Okay so here, what should go in a function?

[gentle urchin]

Stamina use

Is a function

Or should be a function

DepleteStamina or whatever

[candid geyser]

Uhhh I kinda made it all on my own

So n o

[gentle urchin]

Well, good? 😅

[candid geyser]

Stamina for me is a float variable

Hmm I think we can still make it work

[gentle urchin]

Yes, it is

But to deplete it youd have a function ?

Atleast i would

Keeps it clean

[candid geyser]

Nope :')

[gentle urchin]

anyways

[candid geyser]

But I can collapse them into a function B)

Okay so for a start, how can I set the treshold?

[gentle urchin]

When depleting stamina, check after subtraction if you are below treshold

Well you can hardcode the value

Or make another float for it

[candid geyser]

Already part of the Stamina system, I think we're good there

[gentle urchin]

Right

[candid geyser]

Stamina values coming up and down are all handled

[gentle urchin]

So if newly below treshold, call the delegate

[candid geyser]

Oooh okay hang on

[gentle urchin]

Yes you need an extra bool for it ^^

[candid geyser]

Delegate is the pink box right?

[gentle urchin]

Erh, event dispatcher *

You need to create one for the stamina trigger

Name it usefully 😅

It should have a bool input

[candid geyser]

Yup yup working on it right now B)

Okay I have an event dispatcher out

[short reef]

So how do I properly replicate an attack collision/switching collisions on and off?

Because obviously I want my weapons/actor hitboxes to only be active when an attack is going on, but clearly the method I'm using to go about it (using an anim notify state to turn on collisions for actor/weapon hitboxes) isn't working so well

[naive stag]

How can I trace multiple lines around the character to find any collision object?

[spark steppe]

just use a collision sphere?!

[hearty barn]

@sudden zephyr I think I maybe figured something out there's never a negative yaw returned from this but there is in relative rotation

[trim matrix]

Hi so i dont know how to castthe password and the username content to an actor that i need to connect to my tcp server?

[earnest tangle]

This looks so much like a random shitpost

lol

[trim matrix]

its my start screen i did

xd

[flat coral]

Why can't I validate a HitResult? This thing is empty sometimes and it's breaking my code

[earnest tangle]

It's pretty good

[trim matrix]

thx haha

[earnest tangle]

Is valid checks if an object is null, hit result can never be null. You need to validate the specific value from the hitresult which is null

I would assume that would be Hit Actor

[flat coral]

It really really looks like it's null

[earnest tangle]

pay attention to what it says, accessed none trying to access HitActor

[flat coral]

Ah wait I know the fuckin problem

[earnest tangle]

tbh this one is a bit confusingly worded as far as it goes with these

[flat coral]

I wanna stand on a huge rock and scream to the whole world that every coding language needs to have null-safe dereference operations.

Gimme my elvis operator, blueprints!

[sudden zephyr]

they should have replaced the accessed none with Accessed NULL. So much more obvious. Bugged me forever. -.-

[earnest tangle]

That operator is not much different from Is Valid or Validated Get in context like BP's I think

[flat coral]

The difference is when you chain dereference. With validated get, you need to validate each step of the dereference. But an elvis operator just returns null if any step is null, without throwing error on the next step

[earnest tangle]

I suppose so yeah

[sudden zephyr]

impossible xD

[candid geyser]

Hey, does anyone know what the object can be when casting to something?

[hearty barn]

I'm so confused why does this return true but not this

[candid geyser]

Holy shit can it be anything??

[earnest tangle]

It can, but you can't cast anything into anything

it needs to be the specific object you want to cast

[candid geyser]

Oh yes I know

[flat coral]

It's supported in C++, C#, JS/TS, PHP, and Kotlin will lie and say it supports it but it doesn't

[earnest tangle]

try having some other value than 0.0 in there and see if that affects it

[trim matrix]

How can I teleport my player to the cine camera using the sequencer? I tried to get the cine camera transform and plug that into setactortransform and my player just kinda... stayed where he started at

[candid geyser]

When casting to HUD, what do you think I should use as the object?

[hearty barn]

huh ok I entered in other values and that broke it this now returns false why? they match

[trim matrix]

My player doesn't teleport, can someone help plz?

[earnest tangle]

Sorry I meant the third value for the == node

[sudden zephyr]

Because I think you are comparing an old value to current values?

[trim matrix]

Ping me if someone answers me please

[earnest tangle]

You're comparing floating point values, and they are inaccurate sometimes, so you need to use a delta value like 0.01 to allow that amount of inaccuracy in the comparison

if you're comparing 0 == 0 then that tends to work without issues, but if you have values like 1.123123123 == 1.123123123 this can have problems because of how floating point numbers work

[hearty barn]

the values are so far off tho? only the pitch is dead on

[earnest tangle]

I'm not sure what the values you're printing are

[hearty barn]

I'm printing the relative rotation after setting it to that previous screenshot values

p=y

[earnest tangle]

No idea, either something changes the value or it's actually the same value but just represented in different range (instead of negative it shows it as positive or something)

[naive stag]

How can I make it so that I will find the nearest point of trace to my mesh in Multi Sphere Trace By Channel

[sudden zephyr]

What zomg said and to add, that's why you use delta so you can define threshold/precision easier. Like, if delta < 0.1 etc, xD

[hearty barn]

delta didn't work for me and nothing else is changing the rotation so I'm lost but oh well I'll just come back to this another day

[sudden zephyr]

Yeh, take breaks, they do help with stuff like this too.

[trim matrix]

Does anyone know how to get a variable from a widget into an actor??

[earnest tangle]

same way as getting a variable from any other object, you get the widget and read the variable

you can also do it the other way around if it makes sense, assign the actor into the widget and have the widget call a function on the actor to assign it

[naive stag]

Can anyone help me please. I’m struggling a lot

[trim matrix]

Ok guys I got my player teleported to the end of the sequence cine camera. How do I "ease" the cine camera to the player camera?

I tried Set View Target With Blend and set the blend time to 5 but it still cuts to the player camera

https://blueprintue.com/blueprint/0utiqidi/

[candid geyser]

Try adding camera lag

[trim matrix]

How do I do that?

[candid geyser]

Are you using FollowCamera?

[trim matrix]

no

I'm using the level sequencer with a cine camera actor

and an end event to teleport and ease the player

[trim matrix]

You can see here

[candid geyser]

Hecc

[trim matrix]

?

[candid geyser]

I know that adding camera lag will fix it, but I dont know how to find it for your cam

Hang on ill look around

@trim matrix Found it!

Is your camera attached to a Camera Boom component?

[trim matrix]

no

[candid geyser]

O h

Well the camera boom is how you add camera lag

There might be another way though

[trim matrix]

Oh wait

I just need to know the player's looking height

is there a way to figure that out?

[candid geyser]

Looking height?

What do you mean?

[trim matrix]

like the player's camera height from 0

the distance from the ground to the player's camera

[candid geyser]

You could always try to linetracebychannel from the camera to the floor

Maybe

Idk about that but that's my best guess :')

[trim matrix]

I might just go back to Unity

this cinematics thing is hard as hell

[sudden zephyr]

If it's a character where the the origin is where it hits/meets the floor, should be simple then.

[trim matrix]

Ok let me rephrase what I initially wanted to do

In cinematic sequencer, I want to move a camera with keyframes (I know how to do this) and then at the end, when its moved, I want to get the location and rotation, then set the player location and rotation to the camera's

but its not working right

https://blueprintue.com/blueprint/0utiqidi/

[sudden zephyr]

Not working correctly how?

And are you sure the cinematic camera is actually at a location where there's enough room for the character? As in, the camera is high enough so that the character actually spawns on the ground and not in it?

[trim matrix]

it keeps teleporting to the wrong place, normally inches near AND doesn't rotate the right way

I don't know how to tell how high the camera should be

[sudden zephyr]

Hm...

Oh, btw, why are you casting transforms to the actor itself rather then moving the reference?

[trim matrix]

?

[sudden zephyr]

There's a pawn on the level already, right?

[trim matrix]

There's a player start

[elder nexus]

Hello, when doing a line trace, I'm getting only 1 hit for one box, if i duplicate the box in the world i don't a hit on the second one, why is that ?
https://prnt.sc/uJfeq4bVu2l2

[sudden zephyr]

I'm probably wrong but I think--if I read the code correctly-- you are tracing for a reference.

[elder nexus]

Yes, i get the reference of the first box, but not the second one in the level

[sudden zephyr]

If you duplicate a box, it's a new reference, that variable up there with name Box that goes in target I think.

Yes, you get the ref for first box, but what about the second? xD

[elder nexus]

On the second one i don't get anything

[sudden zephyr]

How do you get the box ref?

[elder nexus]

actor component https://prnt.sc/r2Oguw7oBLHC

[sudden zephyr]

Wait, wheres the code located btw?

[elder nexus]

inside an Actor BP

[sudden zephyr]

Ah, ok then. Thought you are tracking a box with the player, but it's like a wall lazer. Huh... Should work. o.O

[elder nexus]

I spend 2 days trying to figure it out, I tried all the lines traces, nothing works

[trim matrix]

Ok I figured out my problem 😄 All I have to do is place the player start where my camera ends, is that the best way, or would you guys do it in blueprints?

[elder nexus]

I tried by tag, doesn't work, it's like it changes the name inside the level and only gets the first actor inside the level

[sudden zephyr]

Wait, how you know if and which one works?

[elder nexus]

It's the first actor placed in the world, that one works only, not the rest

[sudden zephyr]

Hm.. Asking all that because it's confusing as we don't know what, how or why you're tracking. Like, I see you're getting the actor but then track infront so we only at wild guess here of what it's meant to hit, if you know what I mean.

[elder nexus]

So I'm doing a trace to see if I hit the collision Box, but if i duplicate that in the level then it won't hit the second box https://prnt.sc/EC6FtpQnBhvE

[sudden zephyr]

So confused. xD
So you have a wall and you are tracing that wall from the player instead?
It's so weird as depicted here, sorry. xD
You sure trigger box wouldn't work here instead?

[elder nexus]

I can maybe show you if you join the voice channel 😄

I'm tracing the wall from inside the actor

I mean the collision box

[gentle urchin]

Did you manage to complete the setup? Arriving at the pc now if not

[candid geyser]

I took a bit of a different path but yes! It is working!

[gentle urchin]

Damn. Betrayed at the finish line

Well good its working atleast!

[candid geyser]

Oh no I only changed a little bit :')

There were a couple of bugs I had to smooth out, but its all good now!

[gentle urchin]

Aaand the result can be seen... where? 😄

[ivory drift]

I'm following this tutorial for a inventory and I'm following everything correctly but I cant connect these. How do I fix this?

Im doing this in the Third Person BP

[paper galleon]

You're trying to connect an array to a single struct break. Wouldn't work.

You have to pass the array to a foreach loop

Then break each item in the array.

[modest monolith]

HELLO GUYS! Do you know if using Set Hidden In Game I can propagate to only one children and not all of them ? cause I have some stuff that I don't want to affect! Please thank you !!

[maiden wadi]

It's likely easier just to make a function that will set what you need hidden.

[candid geyser]

Oops hang on

Uhhhh how can I record a video to show?

[gentle urchin]

OBS ?

[candid geyser]

I surprisingly have that

Okay hang on

[candid geyser]

Keep an open mind though as everything is VERY early haha

75% of the animations are not permanent

[modest monolith]

I can't.. it's a macro in a macro library

[gentle urchin]

https://tenor.com/view/open-your-mind-mr-mackey-south-park-s2e11-roger-ebert-should-eat-less-fatty-foods-gif-21551170

[candid geyser]

Voila?- I guess :')

It's on its way

Very rough right now

But oh

[gentle urchin]

mkv ugh

[candid geyser]

Why did it

[gentle urchin]

mp4 ty

[maiden wadi]

Feels like something that should be a ticked uobject rather than a macro. Either way, you as passing self in from the character using it. You have access to the entire thing to hide or show specific components.

[candid geyser]

Hang on how do I fix that lmao

[gentle urchin]

under settings -> Output

Recording format

[modest monolith]

So I don't have to modify it from the macro library ?

[candid geyser]

Should I re-record it or did you already see it

[gentle urchin]

re-record 😄

[candid geyser]

Gotcha

Deleting the old one lmao

[maiden wadi]

Well. You would if you want to modify the macro. Your only other alternative is to make a new execution output on the macro and handle the hiding in the character there, call that when you want it hidden.

[candid geyser]

New one on the way!

[modest monolith]

I mean it's a dash where I disappear and blink so my mesh visibility goes off but not my rifle behind the back.. since I have two rifle one on my back and one invisible on my hand If i propagate to children i disappear with my rifles but then when my visibility returns on also my invisible rifle in the hand comes out

[gentle urchin]

well dang!

looks like something could be looping with a 10th of the length, but gj!

[modest monolith]

how did you send a video so long lol i struggle to make it less tahn 8 mb

[gentle urchin]

Nitro

[modest monolith]

oh okay

[candid geyser]

N i t r o

[gentle urchin]

50mB

[candid geyser]

Which expires tomorrow

But

[candid geyser]

What's looping?

[gentle urchin]

the animation could be looping

[candid geyser]

Which one?

[gentle urchin]

the staminabar?

[candid geyser]

Oh yeah it's kiiinda looping

A small portion of it is looping I think

[modest monolith]

Ok then

here's my video

[gentle urchin]

0 = infinity

Change My Mind

[paper galleon]

And beyond

[candid geyser]

Oh no it's not looping!

I always set them to 1 or more loops

What I did was I just made the Low Stamina effects go on for about 20 seconds

So that the animation doesn't end prematurely

[gentle urchin]

right . but it should end when stamina reaches 0 i would think 😄

when the player stops depleting stamina ?

[modest monolith]

here's my video then haha

[candid geyser]

Not quite

[candid geyser]

Nice!!!!

[candid geyser]

If I had it so the animation ended when the player stopped losing stamina, it would cause the animation to end no matter if the player was under 25% stamina or not

[modest monolith]

When you invest in mechanics and not in art XDD

[gentle urchin]

Well its up to you how you want it ^^

[modest monolith]

my game looks garbage

[candid geyser]

So I made it so that the animation would end when the players stamina went above 50 total

[modest monolith]

focusing 99% on the gameplay

[candid geyser]

It looks fine man! Just some polishing and it'll look awesome!

[modest monolith]

Yeah I need to find out how to fix this rifles visibility 😦

[candid geyser]

Right now what im doing is im getting the mechanics working, and then immediately polishing them and making them look nicer

[gentle urchin]

quick mockup

[modest monolith]

Yes .. my friend is just doing maps and stuff.. they look very nice but then the game it's just a mannequin that walks

[candid geyser]

Oh, you're getting help? :0

[modest monolith]

No.. he's doing them for his game

[candid geyser]

Ohhh

[modest monolith]

Amazing map but he did only that

Instead of focusing on the game

[candid geyser]

I care about getting the base mechanic working and THEN polishing it

[candid geyser]

Honestly, mine looks kinda messy

[modest monolith]

Yeah that's the proper way to do it

an MVP

[candid geyser]

I worry about polishing as soon as I can because I have ADHD and I know ill forget xD

[gentle urchin]

ok mine was inaccurate

final

[candid geyser]

What's that MAX program?

[gentle urchin]

its a single ended clamp

[candid geyser]

brain hurt

[gentle urchin]

same with min

[candid geyser]

Okay I think mine needs some cleanup

Because it's looking pretty messy

[candid geyser]

Something possibly worth mentioning by the way!!

@tight schooner ugly

If you cast to your actor, you can drag off and use the variables from there, in the widget

im sorry

[tight schooner]

lol

[gentle urchin]

and the regen function

[candid geyser]

Yeahhhh mine is...

messy-

[modest monolith]

Ok I did it .. I cast to the character in the bp and fuck it

[candid geyser]

What kinds of programs will cause performance drops?

Because I wanna make 100% sure that my game is well optimized

[gentle urchin]

loops

[paper galleon]

Don't worry about optimizations until you need to.

You'll waste time that way.

[gentle urchin]

Dont we love wasting time

Nah you're right

dont preoptimize

profile,

then optimize

if profiler showed anything

[paper galleon]

Actually we do. 😅

[gentle urchin]

we're both here, so yeah 😛

[paper galleon]

Right?

[candid geyser]

Okay so im going to temporarily break the animation so I can clean it up

[maiden wadi]

See you in a week.

[candid geyser]

Aye no

[gentle urchin]

Full speed ahead captain

[candid geyser]

I got this dont worry, I know what im doing now B)

[gentle urchin]

I didnt show you the binding,

but you got that one covered, right

[candid geyser]

Binding for what?

[gentle urchin]

the dispatcher

[candid geyser]

Eheh

That's why I had to change things up

But I think I know a way

[candid geyser]

TRUST ME BRO OKAY

i got it

probably

[gentle urchin]

||erh, i keep forgetting marking them spoilers ||

[maiden wadi]

Last time I said that at work, it took me a week to fix a five minute bug. :/

[candid geyser]

sh

[gentle urchin]

Thats all in the past

[candid geyser]

im cool

[gentle urchin]

i wasted a day on the UMG input

untill i just dumped it down to the relevant actor anyways

re-added the interface and it worked in 5 minutes

Now im wasting time thinking about my datatables

[candid geyser]

(Also, while im doing this, if anyone knows how to make a UI Material for water droplets, let me know)

[maiden wadi]

Would personally do that in the Niagara UI plugin. Probably just as easy with a basic material though.

People love raindrop material textures. I don't think they're any different when for UI, just less vertex manipulation.

[candid geyser]

Actually nvm

Hey. i am trying to create a widget blueprint which displays a progress bar that is bound to my BP_ThirdPersonCharacter's health variable. It is bound to it and it follows it, but the progress bar inside of the widget blueprint only goes to 100% (if the health variable is above 0.0) or 0% (if the health variable is 0.0 or below). Any idea of what might be causing this?

[wise tide]

I am using this event in the gamemode to handle starting behaviour for players (setting them to the intro camera, etc). However it seems to completely overwrite the normal starting behaviour as my players no longer spawn in.

What am I supposed to do so it continues as normal after finishing my custom BP?

[desert juniper]

Percentage goes from 0.0 to 1.0

what you're doing now is dividing their health by 10
100 / 10 = 10

try health / max health
that will get you the progress bar percentage you're looking for

[maiden wadi]

Likely need a call to the parent function if it's no longer spawning characters and you want it to.

[hardy hare]

ahh yes i see now. i multiplied by 0.1 instead of 0.01

thanks

[dusk cave]

I still need help solving this issue. After possessing a pawn then repossessing my character, my walk, run, etc. animations don't play anymore but my character can still move. How can I fix this?

[umbral ginkgo]

messing around with level switching and I cant figure out why this wont work.

When I'm in level 1, I want pressing e to switch you to level 2 and vice versa if that makes sense

[maiden wadi]

For extensibility, it's still safer to just divide current by max. Even if max is 100. Good habit to make when making bars for stats of any kind.

[maiden wadi]

Because you're removing state when you open level. That will always be whatever the default value is after opening a new level.

For more clarity. OpenLevel tells the current world to tear down and rebuild a new one. This destroys nearly everything except for GameInstance. This means that the blueprint you have these controls in is also destroyed and recreated.

Two options to fix. One, save state in the GameInstance. I don't advise this long term, but it's easy for beginners.

Other is to call GetCurrentLevelName and compare the string with your level's names to load the other level. Potentially better extensibility depending on your end goals.

[wise tide]

silly question, but how do I do that? The parent is Gamemode Base but I am unsure how to call the handle starting player function in there from my BP

[maiden wadi]

Right click on the red node. There should be...

[wise tide]

ah, thank you

[maiden wadi]

That should make it run old functionality before the override, and then your set view target code.

[wise tide]

Yep, my issue is gone. There are other issues but they are multiplayer specific. Thanks for the help

[hardy hare]

gotcha

[neon spear]

So im watching a blueprint video and when he opens a widget blueprint the border of 1920x1080 or 180x720 is automatically outlined in blue for him but when I open a widget blueprint there is no outline and I cannot figure out how to add one

his looks like this

[maiden wadi]

Add any widget to the hierarchy.

No widget.

Any widget but nothing hovered.

Hovered widget.

[neon spear]

Thanks

Also a weird thing that happened

I added a progress bar and It was massive and locked in place

but I added a canvas panel first and then the progress bar

and it let me move it around

[maiden wadi]

Widgets will try to take as much space as their containers allow them usually.

[neon spear]

so the canvas panel first is kind of necessary?

[sly forge]

How do you check on which "Text Box lets say" you dropped an item on?, like i want the OnDrop only take actions if the item is dropped on a text box inside my widget

[maiden wadi]

When you add things to a Canvas, they're slotted as a CanvasPanelSlot. CanvasPanelSlots have sizes, and positions. Other slots like VerticalBox or HorizontalBox will only take up as much space as the child requests. SimpleSlots like a userwidget's base will stretch the contents.

Some slots have settings to stretch or not.

[maiden wadi]

Fair question. You could probably math out the pointer operation for where mouse is, and the widget's desired size/screen position. But I wonder if the Hovered check returns true there? Honestly I rarely use Text for hit testability. Usually if I need that I wrap it in a border and set the border's draw to none for invisible.

[sly forge]

I think that will require a lot of math for it to work correctly for every situation, i was hoping if there is a way to return the object that the item was dropped on be it text box, border, canvas panel or anything

[dusk cave]

Why does everything in here work except playing the animations after repossessing the player?

[trim matrix]

I have an NPC that randomly roams around. I have a dialog system set up and I want the NPC to stop moving completley when Im in dialog mode with them. I used Set Movement Mode and set it to None, he doesnt move location but he still keeps rotating to where he wants to move, how do I stop him from rotation as well?

[neon spear]

thanks

[neon spear]

is there a node called set rotation mode or something?

im only just learning so that might sound dumb but from what ive looked through and messed around with it seems like there are movement /rotation variations of alot of stuff

[trim matrix]

i used set rotation rate and set orent to rotation to dont rotate/0 rotation and it doesnt work

[umbral ginkgo]

Would you care to elaborate on the second method? How would you compare 2 strings?

[neon spear]

weird idk then sorry. I barely understand how I just made this healthbar work so IDK. I figured it was worth a shot suggesting it. Sounds like it would work atleast

[trim matrix]

Does anyone have any idea or resource where I could learn to make a procedural rope object of some sort, where I can modify it's length or on the fly? I've been using the cable component for a minute, but it doesn't have physics collisions

[earnest tangle]

You can enable physics on cables but they can be janky so YMMV

I think another method is to have some kind of skeletal mesh for the rope, but I'm not really sure if/how you'd go about having a dynamic length for something like that (eg. you'd probably need to add new bones)

[trim matrix]

my unreal is being a piece of shit. I have a roaming npc and i set only roam if DontMOve is set to false, if DontMove is set to true from class default he doesnt move, if i set it to true through a cast node when i initate dialog itll print to say its set to true but he still keeps moving

Cable physics doesn't seem to work, it goes through stuff.

[trim matrix]

Yeah that's what I'm resorting to most likely

[earnest tangle]

I think there's some paid cable plugins on the marketplace. I would hope they work better than the builtin cable comp lol

[maiden wadi]

Sorry, stepped away for a bit. In your case, you could likely just == to one of them. It should more or less be as easy as this.

[earnest tangle]

What is === ? This isn't javascript, how does that differ from ==

lol

[maiden wadi]

Haha. I think that is the Equal Exactly, including case.

[earnest tangle]

Ahh right it's a Name and those are case-insensitive by default

[cyan bone]

Im confused. I have been doing my whole game using 3 ISM per soldier. One for the soldier itself, and another 2 for shield and weapon.
So i can animate each one separately.
And i LERP them all when i need to move the whole soldier.
But recently i discovered how to animate materials with WPO. So now im considering doing just 1 ISM with 3 Materials and animate the materials.
So should i redo everything?
Whats best for performance?

[maiden wadi]

I feel like if you're trying to go with the TotalWar style soldiers, the new Niagara skeletal meshes thing might be a real way to go if you're worried about performance. I have yet to test it personally, but supposedly it can support several thousands of "soldiers" in a view at a time

[cyan bone]

I have seen it. Its a bit hard to implement. However i didnt go for it, because i want to maximize performance and downplay graphics and animations. So im not even doing the soldiers 3d, they are just planes, and they look alright. So that was my option.

Should i reconsider that? If i make them 3D, then i will also have to make them with fancy animations. As it is right now, i only move them around and move the weapon back and forth. I tested it today and it can handle many batallions.

[maiden wadi]

Fair enough. Out of curiosity though. How do you animate individual soldiers in an ISM? I deal too much with widgets. 😄 Less familiar with gameplay graphics implementations.

[surreal peak]

There are multiple ways to do that

You can animate hismc actually through vertex shaders iirc

With ue5 and CPP it would probably be a good candidate for #mass

[sly forge]

How do you get the parent widget? i have a widget inside another widgets canvas panel but GetParent returns the canvas panel not the widget

[surreal peak]

Easiest way is to pass the parent as self to the child on construct

[cyan bone]

I use update instance transform.

[sly forge]

i'd like to know the harder way xd

[surreal peak]

I do not know how to get the parent you desire as the parent is not just the userwidget hierarchy

You could ask the parent for the parent etc until you reach your wanted widget

[sly forge]

You mean multiple GetParent nodes until i reach the parent i want?

[surreal peak]

Theoretically only one

[sly forge]

Depending how nested the widget is i guess?

[surreal peak]

No

Make a current Widget variable

Get the parent of it

Save it to current widget

Check if it's the one you want

[maiden wadi]

You 'can' bubble until you find the parent you're after, but generally with eXi on this one. Passing the parent you might need to the child widget is much easier and cleaner. That or store the parent somewhere globally that the children can get from World like a HUD class if it's that important.

[surreal peak]

If not, get the parent of current widget and set it again

That way you move up the ladder

[sly forge]

Yea i was thinking of doing it without having a pointer to the parent, i think i managed to do it sometime ago with i believe either Multiple GetParent nodes or GetParent node with some other nodes but i can't make my self remember how i did

[surreal peak]

Multiple get parent nodes is def the worst solution

[maiden wadi]

I wouldn't rely on that. It makes me cringe not knowing what the pointers I'm using might be. Correct framework is too important in UI for several reasons and the forefront of that is simplicity of use.

I'd be too sure someone would come along and add another canvas or other widget somewhere and break the whole thing.

[surreal peak]

The proper solution is the pointer to the parent being set by it

[maiden wadi]

Namely me in 6 months when I forget.

[surreal peak]

I have not walked upwards in the widget hierarchy to find a parent in very long time

[sly forge]

I think i'll just scrap that for now, my main goal was to get the widget under the mouse when dragging an item because IsHovered doesnt work when btn is down

[surreal peak]

But if you want to search anyway it something like this:

1. CurrentWidget = self
2. if (IsWantedWidget (CurrentWidget))
   2.1. true -> done
   2.2. false -> CurrentWidget = CurrentWidget->GetParent()
3. Go Back to 2.

That's why you only need one GetParent node

You just update some pointer to the current parent you are looking at

[maiden wadi]

I have a memory that I did something with that using DragOperations. I know I did something similar to that with them for magicky ui particle visuals when dragging a widget from one inventory to another.

[surreal peak]

And replace it every iteration

[maiden wadi]

Maybe I was relying on MouseEntered. Can't remember. Will run a couple tests.

[sly forge]

MouseEntered is for the whole widget and doesnt work when dragged as i remember

[maiden wadi]

Maybe. Though yeah, I was using it for inventory buttons. Which were their own widget class.

[surreal peak]

That algorithm is basically the one you use to walk a linked list where you only know next or previous element.
It's a good idea to get to know some basic algos from time to time :P

[sly forge]

Thats what im trying to avoid, separate widgets for everything, becuase im sure i will have a messy project

[maiden wadi]

Don't avoid it. Seriously. In UMG and Slate, embrace it.

The simpler and more reusable you make your widgets. The easier life gets.

[surreal peak]

Preferably you create yourself a reusable library of widgets:P

[maiden wadi]

I have a bunch of parent UserWidget classes in C++ that I make BP classes out of to add UI elements to. BP is for little more than the widget hierarchy changes. Functionality mostly lives in the parents, and all I have to to to make a new window is inherit, throw some new UI in, style, do specific window functionality, and done.

[sly forge]

But if you have a widget with alot of features and buttons inside you'll have to break it into alot of separate widgets, is it really the good way?

[surreal peak]

Can't count how often I have coded a button with text, a horizontal combo box, a tab manager etc

[silver bolt]

Hey folks, I'm trying to create a procedural mesh where I place cylinders in a circle. Do you see a way to make this distribute the cylinders evenly in the circle? It seems that I'm doing the calculations wrong because they're clumping up in an interesting way.

[surreal peak]

Yes at least for widgets you use more than once

[surreal peak]

Hehe you should write down what your math does

That way you learn the best what is going wrong

Your first iteration gives you 360 for the angle

The second 180, then 120, then 90 etc

Not what you want

[umbral ginkgo]

Thanks for taking the time to help!

[surreal peak]

You want to divide 360 by your count and save that value before the loop

And then multiply it by the index and use it as the angle

So if your count is 6, it will be a step size of 60, so first is 0, then 60 then 120, then 180 etc.

Which should be what you want

@silver bolt

My phone seems to dislike "your"..

[maiden wadi]

Consider one simple point for this question. Someone created both a Vertical and a Horizontal box. These literally are the same thing with some basic math differing. But in the interest of keeping ideology basic, they are two separate, very reusable container widgets. The same idea applies to Grid and UniformGrid. UniformGrid could easily just be grid, except with differing sizing math from a checkbox. Make small simplicities are a good way to keep stuff much cleaner. The more you stack onto singular classes, the more likely you're going to end up in places where you want to split them apart anyhow because one needs to do something in one place and one doesn't. And the branching just gets too much.

[mental trellis]

That's your problem!

[silver bolt]

Yaaas, thanks @surreal peak

I wonder if we can make a houdini-like reusable operations thing for procedural meshes in UE. Imagine you publish an operation and other people can use it in their procedural meshes.

I'm not sure how Houdini reuses behavior in their node graphs though

[wise tide]

I have a base character which has 3 children. I think built into UE4 when a character is possessed it automatically changes the view target to it.

I don't want that to happen on a specific child. Is it possible to overwrite this within BP?

If it matters I am trying to make an intro cinematic in multiplayer, but when the character spawns in then it forces the view target to them and away from the cinematic. It is ugly to just wait for them to spawn before setting the camera because it jerks from the spawn point into the cinematic.

[sudden nimbus]

https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Game/Player/SetViewTargetwithBlend/

and on the PlayerController, there is

[wise tide]

oo, that screenshot is interesting. let me try it

[sudden nimbus]

It means you might have to set the view target yourself in some cases

But its how you turn off what you want to turn off

[wise tide]

yeah I use set view target with blend, but the issue is I set it and then the character spawns and re-sets it

[sudden nimbus]

yeah

[wise tide]

this option should fix it tho

[sudden nimbus]

Yes, but again, pretty sure it will just not set the view target on first spawn too, if thats fine, then cool

If it's not, you'd need to add some code to make that happen when its appropriate

using set view target wtih blend

[wise tide]

Yeah I manually set it anyways. It works perfectly now, I am glad it was just a checkbox and I didn't need to mess with C++. Thanks for the help

[sudden nimbus]

np, i just read the code

didnt know about this flag until now

[serene bramble]

How do I import a megascan texture?

[teal talon]

Advice: I'm making an arpg game and would like to dedicate host it like ark does. Where should I store the data for stuff thats unlocked to read it between maps and game loads? I setup easy multisave but I can't get my brain around where to put the data. I wish I could just use a simple ini file with all the collectables listed and if they are unlocked. I tried putting it in a save bp but struggling to cast to it to write/read the data. I just need a simple place to store basic info

[pulsar kraken]

hi, set render custom depth works perfectly fine on PC but on mobile, it won't work. Should i have to enable any other options or any other issues ? thanks for answers

[summer crest]

noob question, anyone know what the blue green node is called ? is the blue node LinearColor ? (from a screenshot on the internet)

[ember basin]

@teal talon generally Game Instance class, as it exists for the duration of the game instance (across maps).

[sly forge]

Hovering over it might help tell you what it is

[summer crest]

its a screenshot on the internet unfortunately https://img-blog.csdnimg.cn/20190531160038335.png

[marble tusk]

Looks like a node which converts a vector 2d to a vector. They're using it to set the z of the vector to 0

[summer crest]

yes that's it! thank u very much 🙏

[gentle urchin]

Thats one conversion alright

I usually just multiply vector by vector

VectorA*(1.0,1.0,0.0)

[solar bison]

if I reparent my BP to a C++ class with same function names, will my blueprints get corrupted/crash?

[gentle urchin]

Yes

Personally i added prefix for them

To separate it

But it can become quite messy

So AddToInventory became cAddToInventory

But it also ment Inventory became cInventory...

Never bothered cleaning it up after my conversion was done. Lazy me i guess

[tawdry surge]

It usually renames the BP functions for me, but I delete them anyway once the c++ functions are implemented

Id be more worried about the actual reparenting of the BP class having an issue

[solar bison]

yikes

[short reef]

Is there any way to set up an array filled with a blueprint's components in the editor that can be iterated through for various purposes?

Trying to set up a weapon with multiple points for sphere tracing

[gentle urchin]

I've had nothing but success reparenting any class that i convert 😬 not sure if i was just lucky

If you straight up use the same fn name it complains about it already being used iirc

Renames it aswell perhaps

[solar bison]

yeah????

this is good to hear. I might just try this now

if my blueprints crash/get corrupted I will cry

[gentle urchin]

Its always fixable 😄

Thats why i went for the safest approach tho

Prefixing 😅

Structs etc has to be remade in cpp aswell if you intend to use them(and didnt already make then in cpp)

[solid zenith]

Any way to add float only to one axis in vector3?

[elfin wolf]

just right click on it and press split

[solid zenith]

aa ty

[short reef]

So I tried using sockets for spherecast positions on a weapon and it works so much better than manually creating the actual points in the blueprint, since it makes it easy for the weapon to be inherited

It also results in much more accurate collisions on fast-moving animations

[gentle urchin]

Sweet.

[hallow compass]

Hi all, I’m having trouble restarting a level when the player dies in a packaged version of my game. The restart code works perfectly in the editor, but if I package, it just doesn’t fire. Anyone know how to fix this?

[shadow holly]

So I've got an item pool with each item having a rarity enum and it picks one based on chance on each level up. Just wondering if anyone knows the best place to store this, on the game mode or game instance or something else entirely? Cheers

It currently gets all the items from the data table and sorts them into arrays, just wondering where to store the arrays so they only need to be fetched once

[calm cargo]

How can I find out the type of structures defined in the editor? e.g the padding structure? I want to define my own. I realize that may just be a vector 4, but there are others, and I need a general way to figure the types out

[coarse orbit]

Is there a way to get complex Hit or Overlap events through Blueprints or is it C++ only?

[winged sentinel]

Is there anyway I can change a variable on an instance editable and expose on spawn variable? Basically everytime i change the variable, I want it to run an in editor custom event.

For example if I change the weapon class var in the details panel while selected in world outliner, I want it to trigger this custom event.

[versed sun]

Read your variable in the construction script, every time the variable is changes , the construction script runs

[maiden wadi]

Generally speaking, I wouldn't worry about the fetching it multiple times in most cases unless you're doing this nearly every frame. Datatable lookup is fast. If you really want to store it somewhere though, I would probably advise GameState. GameMode usually shouldn't have a lot of actual data in it, it should largely be for safe server side processing. If you go multiplayer, this makes it so that players can still see the state when it's replicated.

[maiden wadi]

I'm not sure how you'd handle that in BP. In C++ you can override some post edit functions. If construction script runs after property edit, you could maybe use that.

[shadow holly]

Okay thanks. Yea I only had it on a level up screen that pauses the game so maybe I should just leave all the functionality on there and sort the tables each time

[maiden wadi]

Yeah. I wouldn't bother unless you're doing some Diablo level stuff where you kill 100s of things on screen and they drop stuff based on those tables a lot. 😄

[shadow holly]

Yea definitely wont be using it that much haha. Although I'm thinking of adding an item shop into the game as well which would work similarly, would I be better off storing it in the gamestate then just so I don't have to code the fetching and sorting on multiple menus?

[maiden wadi]

Maybe. At that point I feel like you should consider looking into DataAssets. Datatables are nice, but they're static and have no functionality besides just holding data. DataAssets can both hold your datatables as properties, and also have functions in them that can pull sorted data, or whatnot. And you can get them globally from anywhere since they're static data.

I love Datatables for data entry. Their ui makes it much easier to do. But DataAssets make sane UI data handling possible. 😄

[shadow holly]

Oh that does sound much better actually, I thought it was weird that there wasn't really any functions to work with data tables and that must be why haha thanks for the help

[trim matrix]

Hey guyz, what's the node to draw the complexe collision on runtime?

[winged sentinel]

Good point I think it might, unfortunately tho u can’t spawn stuff in construction script

[icy dragon]

You can't spawn actors in Construction Script, but you can create components.

[gentle urchin]

You can spawn with editor functions tho

And probably loop around the construction script limitation by stuffing the spawn in a function aswell

The usual loophole

[earnest tangle]

It sounds like a recipe for a disaster tbh lol

[maiden wadi]

They actually fixed that in.. 4.26 or 4.27 if I recall. 😄 Cause, y'know. Fix the stuff people mean to do intentionally, not the stuff that actually needs fixed.

[winged sentinel]

I thought of putting it in a function but I didn’t want to jerry rig it lol

[gentle urchin]

😆 damn

[quaint fog]

Say I have an open world survival game. What would be the better implementation of the world's subsystems? A separate actor placed in the world for each system? (audio, weather, Day&Night, etc) or should I make a single actor world manager that has all of the things listed above as components? Or maybe it shouldn't be an actor at all? and should be managed in the game mode?

[maiden wadi]

If you're blueprint only, then maybe a component on GameMode/State might be better. Depends on what it's managing. If you're using C++, then a literal WorldSubsystem would be good for a world subsystem. 😄

Nothing really wrong with dropping an actor into map too if you want, but it's tedious to have to remember if you have multiple maps.

[quaint fog]

I am blueprint only, c++ is too much as of now hahah

Got it, thanks, i'll lkely do components on the game mode

[maiden wadi]

Maybe the component. If you ever go C++, it'll be an easy translate to a real subsystem.

[quaint fog]

aye, thank you 🙂

[mortal cradle]

Do I understand it right that if I have a custom event with let's say 15 nodes in it and I call this custom event from a different BP then it fires the event and moves on immediately without waiting for those 15 nodes from event to finish?

[maiden wadi]

Depends on the nodes. If they're not latent, then no. In computer logic, everything is one by one in order of logical operation. Latent nodes like delays start a timer and only continue after that timer and the timer isn't evaluated until next frame. So any non latent node will run in order until it's done.

Case one for non latent.

And with latent.

[turbid fractal]

Why i cant insert blueprint into that type?

[glass stump]

I've made a simple proximity door, however the player frequently leaves the box collision area before the door has finished opening, meaning it doesn't trigger the 'door closing' event went the player leaves the collision area. Any ideas how to fix this?

[worthy tendon]

use Interface Class instead of the actual interface.

[mortal cradle]

@maiden wadi Hmm... that's interesting, I was reading how we can't know when custom events finish, that we only know when they start, but from what you are saying it seems like non latent functions will always follow the order. That's a bit less headaches, thanks for helping out

[turbid fractal]

thank you

[worthy tendon]

hmm, you cant use interface it seems. but you can use class.

[maiden wadi]

I think that might be a badly phrased point, or just someone who doesn't understand, I don't know. It is true that you can't always know, because you don't know if someone can latent it later or not. As someone who authors the entire logic chain though, you can absolutely know. If you need that form of security, you can just make the event a function too.

As functions cannot take latent nodes.

[maiden wadi]

Either start closing the door immediately. Or when the door finishes opening, check if a player is in it's range and start closing it there.

[glass stump]

Is there a node to check if the player is in range?

Oh wait I found it, thank you! :D

[trim matrix]

Hi everyone, do you know how to plug in 'ignore' input an array of StaticMeshComponent?

[gentle urchin]

Its actors to ignore

Not components

Component != Actor

You'd need to filter that yourself

[neon spear]

The issue is it is doing true regardless of that boolean being true or false

[broken wadi]

I highly doubt that. It's more likely that you think its set to false when its actually set to true. Try adding a breakpoint and stepping through the nodes one by one confirming the values are what you expect them to be.

[last walrus]

hello guys
can you help me with vector maths? everything I want is some ray from X point that goes by red pointer then greent pointer and stops at blue dot

[trim matrix]

how can i filter that ?

[bronze hill]

When i switch Gamefeatures into active, it just activate dosen't it? but it doesnt 🥲

and "ChangeBundleStateForPrimaryAssets failed to find NameData" what this means?

[mental trellis]

Do you have the starting position of the red vector, the red vector itself and the blue dot's location?

[last walrus]

1)start - yes
2)red vector - yes
3)blue dot - no. thats what I need to get

[mental trellis]

So how do you know where it should stop?

What is the logic for saying, "yup, this is where the blue dot should be" ?

[neon spear]

just went through everything I know to try. I tried having the game set the booleans to false at beginplay. I tried it where I had the default value as false I tried having the boolean inside my character and out and regardless it always executes true and I am not sure why

[last walrus]

I want length of green vector to be ~1000 of whatever UE measures distances

[gentle urchin]

Apply your filter on the hit array

[icy dragon]

I think there is a node to get the reflection vector/rotation, not sure what it's called

[mental trellis]

So green vector is always -1000 in X direction?

[broken wadi]

Add a breakpoint (F9) and step through the code (F10)

[neon spear]

on the branch?

[bronze hill]

i want to test lyra's PROTO inventroy feature, i did activated this features somehow accidently last time but now i did try it again, it dosen't work. and i can't figure it out how this turn on.

[broken wadi]

UE doesn't just randomly think bools are true when they are false and vice versa. The problem has to be that you expect it to be one value but its actually another.

Set the breakpoint on the start of the event, just anywhere before you are checking it on the branch.

[neon spear]

Thanks

fixed it

[last walrus]

direction on the screenshot is just for example
I want to know how do I make some vector turn left/right/upwards/etc after some distance
like on this screenshot

[icy dragon]

Add the vector with a forward vector from a rotation?

[mental trellis]

RedVector (normalised) * distance to corner + Rotate(RedVector (normalised), Rotator(0, 0, 90)) * distance left to travel

That would rotate it right 90 degrees

-90 for left

Your red vector might be ActorRightVector or whatever the name is

(for right) ActorRightVector * -1 for left

[gentle urchin]

If you know the vector points (like from navigation) it is quite easy to trace along the path

[last walrus]

well... looks like I fucked something up... can you tell me whats wrong? I really dont get it...

[mental trellis]

You rotator should be on Z, not Y

Other than that, no idea!

[last walrus]

when I set it to Z the problem remains
and I want to rotate in all 3 axis

[sacred canyon]

why am I still getting an accessed none error, even when using an IsValid check? how can it physically be wrong? and nothings even wrong in gameplay, I just want this error to shut up

[split crescent]

I'm making a character creation screen and want to store relevant info such as an array of character classes to choose from.

Should I store this in the level blueprint or in the game mode?

[gentle urchin]

Single or multiplayer?

[split crescent]

Single player atm but curious how it would differ in multiplayer

[desert juniper]

would be a good use of either data tables, or Data Assets

you could add all associated trait modifiers
such as humans have 1.2x speed, humans have 0.8 charisma, etc

then when giving the user a selection, just load up all available the data table/data asset, and automatically apply all character trait modifiers

[icy dragon]

> atm

So it will be multiplayer later on?

[bronze hill]

i found out something weird bug, when i start lyra game it dosen't proto feature on despite of activation

but i press save actionsets , it suddenly features turn on

i just press save, then it working now on. but after restart editor i should do it again.

maybe it conflict with EnhancedkeyMapping, but i don't know.

LogAssetManager: Warning: Invalid Primary Asset Id LyraExperienceActionSet:LAS_InventoryTest: ChangeBundleStateForPrimaryAssets failed to find NameData

and this one is also i can't figure it out

[split crescent]

Yeah let's just say it's multilayer

[icy dragon]

I mean, it's something that has to be decided early on. Multiplayer will be more picky in the workflow..

[split crescent]

Yeah that's true but it seems like a lot of different things to calculate when the user switches classes. I have a lot of their stuff set up as data tables/assets in each respective blueprint instance so it seems to make sense just to switch instances

[mental trellis]

Converting from SP to MP can involve rewriting your entire game and all your animation assets if you do SP badly.

Just a heads up!

[quartz parrot]

hey guys ! I've been having this issue quite a while and even tried different AntiAliasing methods and disabling Motion blur but nope. I get this weird looking effect on every Emmisive Material

havent found a solution on the forums ;/

[mental trellis]

Looks like temporal AA

[quartz parrot]

tried it, and TSR as well

TSR gives me good results overall, but this kind of emmisive rotating and moving stuff gets glitched

[vapid ibex]

How can I run multiple copies of an event with a delay node in it? I can't turn it into a function (cuz of the delay), and I can't simply retrigger it since it might not finish by the time it is triggered a second time.

Context: It is a function that triggers a list of other actors in a scene with delays. In this particular actor, there's two lists: one it starts at the beginning of it's function and another that it triggers at the end of it.

[teal talon]

Then on save I save the game instance data? and on load replace it back in?

[dawn gazelle]

Short answer is you can't. Long answer is that you can add a component that manages each individual delay that automatically destroy themselves when the timer is done.

[vapid ibex]

Damn, that sucks. Though, maybe good actually, for now I'll modify the logic so that the second targets will begin triggering only after first were finished (the actor will remember that they are to trigger)

[gentle urchin]

You could sequentialize them in an array, and only start unique countdowns

[limpid bronze]

hey

for the character controller

why does it teleport anytime I change a parameter?

[maiden wadi]

Character Controller? Sounds a bit like you did some movement setup on the Construction script and it's running on property change.

[limpid bronze]

Like when the game is running in editor

and I change a variable in the character movement

they just teleport

[limpid bronze]

here's an example

[undone surge]

is there a way to stop a delay while its playing

[maiden wadi]

Yes. But not in Blueprint alone.

[undone surge]

aah'

is there a workaround in bp ?

[maiden wadi]

Using timers instead.

You can use a timer's handle to stop it.

[undone surge]

ok thankyou

[limpid bronze]

there's nothing in my construction script.

[blazing kite]

Hey, is it possible to import a material inside another material? Or do I have to convert the 1st material into a material function?

[maiden wadi]

Hard to say. Definitely looks like some sort of post edit reset. Hard to guess beyond the construction script.

[limpid bronze]

Weird, I thought if it would reset; it would have sent it back to the player start.

[tight schooner]

Better question for #graphics. Not sure what you mean by import. You can make material instances (static or dynamic). You can render a material to a target and use that target as a texture.

[limpid bronze]

Does anyone know what I should be editing for the character movement variables; I want my player to be harder to turn but still stop normally.

because currently all I can do is lower the friction, which does make him harder to turn, but also makes him act like he's on ice whenever he tries to stop.

[tight schooner]

The crux of the issue is transparent materials don't contribute to the motion vector map, which UE uses to retarget previous frames into temporal AA, and to do motion blur. The result is that motion ghosting you're seeing. Not sure what the workarounds are other than make stuff opaque or don't use temporal AA. Ask #graphics.

[blazing kite]

Thanks, I didn't know where to post.. What do you mean by "render a material to a target" ?
And by "import" I meant get the output of the material inside another material (to tweak base color for example, and add more functionalities)

[tight schooner]

Idk the process in detail but you can make render target assets, and use Capture components to render perspectives into it. Idk offhand if there's a version that renders materials into textures alone.

[blazing kite]

Oh yeah I see

[tight schooner]

You can add parameters to master materials in the material graph, and then create material instances of that where you can adjust the parameters

(in addition, in blueprint you can make dynamic instances if you want to set or animate the parameters during gameplay)

[blazing kite]

Thanks, I think I'll convert the material into a material function because I would like to keep the base simple

[tight schooner]

@blazing kite https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphics/Materials/HowTo/Instancing/

[blazing kite]

Yep I know this stuff thanks ^^

[vagrant oracle]

Dose anyone know how to do a lock on system like zelda?

[quartz parrot]

thank you very much!

[tight schooner]

Not entirely. I imagine you have to do some [shape] overlap actors thing to produce a list of targetable enemies in view, sort the targets in some fashion to select the most likely one the player wishes to target, and then use the Find Look At Rotation node to make the player face the target. I'm sure there are a lot of game-feel subtleties involved too in making that system feel nice. Override turning with strafing. Highlight the targeted enemy. Switching targets. Etc

[vagrant oracle]

Ok thanks for the info.👌

[undone surge]

is there a way to remove an actor from an array without providing index ?

[blazing kite]

Yep, just use the "remove item" node

[undone surge]

yes i found it thank you

[crude isle]

yo

for some reason

my line trace doesnt end directly in front of the camera

How can I fix

[gentle urchin]

how do you expect it to ?

[crude isle]

wdym

[gentle urchin]

how do you expect it to end in front of the camera?

you're not providing the camera location

[crude isle]

but it got its forward vector

[gentle urchin]

yes?

added to the actors location

so its directly away from the camera

[crude isle]

tf

well I want it to start at the actors location

and end directly in front of the camera

[gentle urchin]

in front of, or "on" ?

for the latter, just provide the camera location

[crude isle]

in front

[gentle urchin]

if you want it in front of you can invert the camera forward vector, multiply it by some number fractionally smaller than whatever cameraBoom length you got

[crude isle]

my brain hurts

[gentle urchin]

just do *-1

on the forward vector of the camera

and multiply by camera boom length

add that to the actors location

= Profit

[undone surge]

how do i make an actor not be able to go into the array again of get all overlapping actors after removing it.

[gentle urchin]

add it to some ignored list

[undone surge]

is that a function or node in game or will i have to make one

[gentle urchin]

you need to make it

and remove them from the list of overlapping actors if the actor also exist in the ignored list

[undone surge]

i c

thnx

Does anyone have an Idea how to cast an String from a Widget to an Actor?

I dont know really how i can explain this. But basically i need to get a Variable from an Widget to the Actor because in the Actor theres my tcp client

[ember basin]

Yes ... of course there are other ways and multiplayer considerations if applicable, but the class is intended to handle data across maps.

ah iknow why

you mean when i receive it put it in a variable first and then make stuff with it?

yeah it does it when the actor spawns

hello, in this tutorial he uses a function called vector * float that i don't seem to have. its tooltip in the vid is Scales Vector A by B and Target is Kismet Math Library. I found it listed online but idk why i can't use it

[trim matrix]

I got a plugin from the marketplace called tcp client and server. Thr problem on the String to Byte thing is that i cannot connect the string pin to anything bc its put there as an output lmao

[mental trellis]

If you put UPARAM(Ref) before the FString parameter, it will fix it

(in the c++ source)

[trim matrix]

the problem is i cannot open it. Its saying reading c++ symbols but nothing more

[mental trellis]

Shrug

[trim matrix]

is there a selector in the options where i can select visual studio version?

[mental trellis]

Or, tbh, just make it a const FString&

Just edit it with notepad

It's a quick edit right?

in the plugin folder?

yeah

its not in the plugin folder..

[mental trellis]

Your project/Plugins?

oooh

nah its not there

aah i got it xd

[mental trellis]

Find the function signature and change it... assuming it's meant to be an input parameter.

[trim matrix]

i got 2 folders

[trim matrix]

got it

[mental trellis]

Change FString& to const FString& (both there and in the header)

[trim matrix]

okay

nah its still there

[trim matrix]

i dont know why its not working

[mental trellis]

Did it recompile?

You migthj need an IDE for that.

[trim matrix]

ugh eh

can i simply put it into visual studio?

[mental trellis]

You should be able to generate the solution files from your project file

And then open that with VS.

[tight schooner]

Not sure, but experiment with world and local space. Usually issues with things not tracking or being unexpectedly offset arise from that. Your "get transform" node has a world/local toggle, and you can set world space transform instead of relative (local). Play around with that.

[trim matrix]

that one?

[mental trellis]

In explorer

[trim matrix]

nah still there

[mental trellis]

Yeah, that.

[trim matrix]

still not working

[midnight ravine]

is there a blueprint node (or other way) that allows you to check if the currently running game instance is a packaged game?

alternatively, any way to check which build configuration the current instance is using?

background: I've got some logic I'd like to run based on if it's being played inside the editor or in a packaged game/standalone version.

Looks like there's only a way to do this in cpp for anyone else checking: https://forums.unrealengine.com/t/is-there-a-way-to-check-in-blueprints-if-your-in-standalone-game-or-not/284133/14

[tight schooner]

Yeah there's some built in node like "is packaged for release" or something

Try searching the node library

[obsidian dirge]

Hi guys! I‘m new to the discord and to unreal engine and i‘m having a hard time fixing an issue on my first game: i‘m working on an endless runner but i want the player to be able to fall from the plattform but i can‘t make an “infinite” kill volume so i iconsidered making the kill volume follow my player on a single axis so as the player moves forward the volume will always be bellow them and make sure they die if the fall… any sugestions as to how i can acomplish this? Thank you very much in advance guys

I’m also having the exact same problem with the player start so when they die they can respawn where they left off so if there’s a way to also get that to follow the character or having some sort of checkpoint on every tile that would be a huge help. I haventbeen able to find anything online that helps 😭

[fiery glen]

You could quite quickly create a blueprint node that does this

(of course, that would require a C++ UBlueprintFunctionLibrary)

[fiery glen]

the suggestion here is to generally make the world move around the player and have the player just look like they are running across it

[ember basin]

Free plugin with IsShippingBuild node and more on the marketplace LE Extended Standard Library

[obsidian dirge]

That makes sense but my character is just a ball with applied forces and getting pushed around by enemies so keeping the character static and moving the world may not give me the desired result. I already have spawning tiles and i was hoping something similar could be done for the kill volume

[fiery glen]

In this case it's more about not having them move forward towards the uh, direction the runner goes in

in case it is just one way

[obsidian dirge]

Here u can see a bit about what i mean

[ember basin]

You could just check your z position, if you are below the tiles respawn at a position slightly back in correct position

[fiery glen]

just hope you don't go more than a few kilometers or so out max to avoid floating precision issues

should be fine though

[obsidian dirge]

How can i do that? It sounds like what i’m trying to do, but when the ball falls i can’t kill it and the respawn is at the beggining of the level which gets deleted after a couple seconds

[fiery glen]

you could also track the last position the ball was in

[ember basin]

Yeah, just check the ball world location on tick, if the z value is below the track significantly you need to spawn it back on the track, or just move it to that location would probably work.

[ember basin]

If the track is flat, you can also store the position if it is on the track z position, then use that as the restart location

[obsidian dirge]

Thank you so much guys! I’ll look into all of these suggestions

[obsidian dirge]

Yes it’s a flat track and i’m trying to set up the respawn system to get the x position so it respawns on the world but for some weird reason nothing seems to work and it goes back to the begining of the level

Probably because i’m not familiar at all with coding so i must be doing something wrong

This is my set up to get the x location of my character

And the spawning set up

[keen anchor]

Performance wise, is there any good place to store a player BP reference that can be accessed globally?
Like casting to player in game instance once and getting the reference when needed instead of casting to player in specific BP's.
Would that reduce memory usage/increase performance or would it just be as bad/worse?

[dawn gazelle]

If it's single player, then just create a blueprint function library and create a pure function that gets player pawn and casts it and then returns the appropriate player BP you want to use. Then you can just call that function globally and get a reference to your player's character.

There's nothing specifically wrong with casting when you need to. Casting only starts causing problems once you start casting like 100000 times a second (eg. On tick, looping through a large loop where you're casting to get the player character on each loop, but why would you do that when you could do it before the loop and then you're only casting 60-240 times per second depending on frame rate).

[keen anchor]

Alright, excellent answer, thank you!
Will look into blueprint function libraries more, haven't worked much with them.

Not sure if i overuse casting, i try to use it on begin play everywhere i need it and store a reference, i just feel i used it in a lot of places and worry it might slow things down/use a lot of memory.
Some people seem to avoid it like the plague and say it's terrible for performance, hard to know what is what 🙂

Now that i think about it, is it bad to create the ref on begin play? Maybe it bloats memory with everything storing a ref to player (as that is a big class in my case)

[gentle urchin]

You should think a bit about which classes you tie together tho

[dawn gazelle]

Nothing wrong really with storing a reference to it, but then you have to make sure the value gets updated if it ever changes eg. if the player's character gets respawned.
A reference is merely a pointer to the data, not a full copy of the object itself in memory, so it's relatively small.

[gentle urchin]

Its also good practice to keep variables private, and have functions for modifying them instead, to give you easy troubleshooting/refactoring/adjustments later on without having to check a ton of other classes

[keen anchor]

Ah right, so reference could break if the player gets respawned and the level isn't reloaded since the object referenced would have changed? Never thought about that, thank you!

[gentle urchin]

It could break*. Depends on how you restart the level really. Other actors can bind to an actors on destroyed tho, so you can react accordingly

[orchid garden]

i have a bpi call to get a player reference, don't need it too often so it works well for me. only other place i store a reference to the player is in the manager component on the player, and for respawning I just pass a reference to the game mode from the character.

[gentle urchin]

Many ways to handle this^

Sounds reasonable

[orchid garden]

( i is tired, late night had to fix my repetitive typo lol)

[keen anchor]

lots of great stuff, thank you everyone! 🙂

[ember basin]

Use OnTick, not OnBeginPlay to collect the spawn position, at the moment it is only when you begin the game. Set the correct Y and Z values for the Spawn position as well, but just align the restart to the center of the track.

[orchid garden]

wouldn't on tick set the position every tick? if you want them to respawn at the death spot i guess that would work

[gentle urchin]

Cant you just fetch loc on death?

[ember basin]

Yes, at the death spot x value, but aligned to the center of the track. Preferably gate the tick with a check for the z value prior to storing the position

[pulsar meteor]

Hey everybody. Has anyone had an issue with aim offsets in UE5 jumping all over the place as if the offset is being reset and reapplied every tick?

[ember basin]

Wants to check if it has fallen off the track, check the z value. Just keeping it easy for a newbie

[orchid garden]

think it would be simpler just to get it on death like @gentle urchin said, so your not constantly setting a variable that you really don't need to.

[gentle urchin]

OnDeath-> GetCurrentTrackPosition -> save as respawn position

Is this mario kart like? 😅

Oh nvm ball rolling

Well i guess it could be a tick check. Id prob just use collision volumes

[orchid garden]

ticks going to give same result as a on death though.

best to avoid using ticks when its not really necessary.

[ember basin]

its just a quick way of doing it volumes work fine, but its their first game.

[gentle urchin]

Makes the tick approach even worse then, imho

[orchid garden]

thinks back to when i first started
If people would of told me the correct way, rather then the 'quick' way on things, I probably wouldn't of had to recode, recode, recode.

no offense... just saying 😉

[ember basin]

I agree you shouldn't use it needlessly, but in this instance its probably more useful than trying to explain setting up a moving volume for a small endlesss runner

[gentle urchin]

Not just that, but the programmer may not be aware of the potential cost of using tick, how often its executed, or why its bad to do getallactors on tick with a looping distance check and whatnot

Anyhow :)

[undone surge]

if i have a collision sphere on a character how can i see it in the game ? it there a way to make it visbible like sphere trace etc ?

[gentle urchin]

^ theres a setting, hidden in game

[orchid garden]

select the sphere - uncheck hidden in game, and you might want to change the 'draw size' from 1 to like 5 so you can see it easier in game.

[undone surge]

thank you

[ivory adder]

I have this connected to a event tick but it is being run multiple times instead of once, have can I make sure it only runs the code after the set delay to 5 once

[gentle urchin]

show more code

I would suggest using a Timer instead tho ^^

[ivory adder]

timer?

[gentle urchin]

yes

A timer can run every X seconds

[ivory adder]

im lost

[ivory adder]

what would that do tho

[gentle urchin]

run every 5 second

[ivory adder]

I want it to check weather a value is == 0 and when it is to send a message 1 time

but it runs it 2 times instead

[gentle urchin]

well show more code then

floats are inaccurate

so checking for 0.0 is usually not a good idea

why it runs twice, nobody can tell you based on what you've shown

[gentle urchin]

check if the delay is <= 0

[ivory adder]

i did that first

nothing

[gentle urchin]

thats the correct way of doing it , if anything

anything else modifying "Delay" ?

[ivory adder]

only making it smaller

[gentle urchin]

well based on whats shown, nothing can make that run twice

in one frame

[ivory adder]

yeah well idk either, when i put a print string after the set to 5 it prints it twice

[gentle urchin]

in two frames i bet

[ivory adder]

?

[gentle urchin]

need to see more of the logic

something is messing with your delay

resetting it at some point

if it fires twice

[ivory adder]

that is all the logic

[gentle urchin]

Well ok then

doing this on tick, removing 0.5 from a 5.0 delay on tick,

its gone in 10 frames

at 60 fps thats 16ms

[dawn gazelle]

Unless he's set the tick rate to 0.5

[gentle urchin]

Doubt it 😛 but could be, i guess

[ivory adder]

?

[gentle urchin]

Have you set the tick rate to 0.5 ?

[ivory adder]

tick rate for what

[gentle urchin]

the actor running this code

[ivory adder]

don't think so

[gentle urchin]

16ms @ 60 fps it is then

[ivory adder]

this?

[gentle urchin]

yeah

I'd suggest moving this away from tick in the first place

for two reasons

1. It doesnt seem to really belong to a "per frame execution"

2. It can become very costly to use tick if you're not sure exactly why or how often it executes, and deciding if your code is fit for such rapid execution

Hint: Most things are not fit for tick
