blueprint

[meager spade]

Because it's not a new frame yet

[undone quiver]

I think we're not really disagreeing 🙂

[forest sable]

This Happens with this code

[undone quiver]

May I should say don't think of it as a snapshot in time

[forest sable]

The first time i enable that time line it kinda works ... after releasing and clicking again it freaks out as the rotation keeps ading to itself although the delta gives me 0

[spark steppe]

set the "old" value once before the timeline

or it will refer to the old value on the first frame (now all in my mind is time 😄 thanks guys)

[forest sable]

That Fixed the Wrong rotation at the beginning but the second click still freaks out

[spark steppe]

it could be flipping around an axis, not sure

you cant force that freak out on the first click?

[bright frigate]

I don't know why my brain isn't working anymore, but what am I supposed to pin into the wildcard so I can get the variable into my widget?

[odd ember]

the thing you want to cast

[bright frigate]

it asks for what MySunPositionBP inherits from, which is the BP_SunPosition

[odd ember]

it craves it

[bright frigate]

yea but I can't get it in the list, it only shows its variables not the actual bp like regular bps

[odd ember]

you have to add the communication for it somewhere

the cast node isn't a magic node that will get you what you need

[bright frigate]

I didn't say it was lol

[spark steppe]

most likely you'll do a get actor of class in the construction event and save the reference on the widget

[odd ember]

well the way you've set it up that seems to be your line of thinking here

[spark steppe]

pretty short line

[odd ember]

I think there is a pinned video on blueprint communication in this channel, I suggest you watch it

[bright frigate]

I decided to do all the stuff I was doing for day night into a separate class as recommended earlier, so I made a new class that inherits from the plugin class

I had a get all actors and promoted to variable as sun position object in the level bp, but now I've moved it into event begin play in mysunposition bp instead. Should I have done it in the level bp to access it in the widget?

[odd ember]

get all actors is a cheat code basically

it supercedes good architecture by allowing you to call things without connection

however, the level blueprint naturally has knowledge of all actors inside of the level

[gentle urchin]

^for a while thats what i used the level bp to (long time ago), connecting up relating bp's that didnt have any ordinary means of communication

[odd ember]

it's still valid to use for level specific logic

[bright frigate]

a while ago I was told that I should separate something like time from the level bp so that I can have multiple levels. While I don't need that now, I decided to try it out for learning's sake

[gentle urchin]

For level specific logic (i have yet to encounter something specific enough), I'd probably just hard reference it

[spark steppe]

where do you create the widget? can't you just pass the actor as reference on creation?

[bright frigate]

character bp

[odd ember]

IMO this is architecturally unsound

[bright frigate]

I followed a tutorial that was for a character-related HUD, so I'm kinda adapting it to this

[odd ember]

it also makes it really hard to maintain visibility of what is going on

[forest sable]

Nop, It always Plays right the first time ( sorry i was away )

[odd ember]

since you'll have to check every actor for specific things, on the actor

level BP exists for a reason

[gentle urchin]

True that. Not perfect in any way

Just feels dirty using level bp

[odd ember]

why?

[gentle urchin]

some comment some time ago that stuck with me that i cant recall

[odd ember]

it's way dirtier using hard references

[bright frigate]

ok so what's the suggestion?
mysunpositionbp is handling all logic for time
widget is being added to viewport in playerbp
I need variable from mysunpositionbp to bind it to the widget

[odd ember]

if you're doing hard references you might as well be doing get all actors of class

it's the same thing

just once deferred

[gentle urchin]

Well, you'd need some method of picking the correct ref with the get all method

[odd ember]

it also actively prevents you from creating good architectural setups

[gentle urchin]

so you'd need some unique identifier (tag) or something to get the right reference

[odd ember]

or just use the level blueprint

which was made for this purpose

[gentle urchin]

To connect a button to a door ?

as an example

[odd ember]

yes

[bright frigate]

guys 😄

[odd ember]

level BP even allows you to use delegate calls as events so you can have events for level actors directly in the level BP

[odd ember]

use the cheap GetAllActorsOfClass if you want it quick, or pass a reference on widget spawn and get up to speed on BP communications if you want to do it the harder (but ultimately better) way

[gentle urchin]

Guess i could open up about using the level bp for stuff, and avoid hard refs. I usually stay away from hard refs like that in general, for the same reason i dont hard code values in the code etc

as you point out, having to check X actors if their hard refs are correct is just a pain in the ass on a level thats bigger than the template-level

[bright frigate]

I just did this before reading this message. Is it correct?

[odd ember]

probably? if that's what you want?

I don't know

it's a line of code that makes sense

[gentle urchin]

^ Get it once, save it, and use that ref? This looks like a binding ..

[spark steppe]

yea^

[bright frigate]

I just wanted a reference. Normally it's pretty straightforward to get stuff done e.g. get player character -> cast to character BP in everywhere else but in widgets I've encountered this. I did widgets like 2 years back last so it's pretty much gone from memory

[spark steppe]

#blueprint message

[odd ember]

generally I stick to the format of having all level scripting done on a separate level

[spark steppe]

i told you 20mins ago what to do

[odd ember]

which is not the same as the persistent level

[spark steppe]

why don't you just use that as solution for now?

[bright frigate]

Missed it because of the other discussion that pushed it up

@spark steppe I have the reference saved in the my sun bp itself in this same get all actors method (I copy pasted it from level BP so I'm sure I don't need to do this anymore in this format)

this was in level BP before

so should I put this back in the level BP in order to get the object in the widget?

[spark steppe]

you just do the same in your widget

[bright frigate]

okay

[gentle urchin]

on event Construct

[wraith bay]

Is there a way to check if the player is in a specific level?

and make a boolean out of it

[spark steppe]

i think there is an "is actor in level" node or something

[odd ember]

not in BP I wouldn't think

you'd need a reference to the player globally

[bright frigate]

okie dokie, done, thanks

[odd ember]

in fact the only place I can even see that check being made is in a World Subsystem

[spark steppe]

yea right, you need c++ for that

[wraith bay]

cool thanks

[bright frigate]

giant trigger volume and begin overlap 😂 (don't do this I'm probably wrong)

[odd ember]

https://tenor.com/view/kendo-shinai-bonk-doge-horny-gif-20995284

[bright frigate]

+10 points for creativity at least? 😄

[spark steppe]

for something that 1 line of c++ can do?

bool AreActorsInSameLevel(AActor* actorA, AActor* actorB){
    return actorA->GetLevel() == actorB->GetLevel();
}

[gentle urchin]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Game/GetCurrentLevelName/

[odd ember]

level specific logic is generally off limits to BP because it requires access to World

you could perhaps query the player for their current level

however

[forest sable]

Okay I found Out If i click It and not rotate then realese and click and rotate it acts correct.. meaning that if the rotation of the object is not default (untouched ) then it will freak out

[spark steppe]

how do you calculate your rotation?

[gentle urchin]

This is in the Playercontroller, and atleast so far its working

[odd ember]

.

what I was saying is that you can't e.g. loop through each level inside a level

[gentle urchin]

Makes sense. My simple mind has not been exposed to multiple levels inside a level sort of experience.

[odd ember]

multi level management

persistent level knows its sublevels

world knows all persistent levels

[gentle urchin]

Ah. Nice to know. Will come in handy at some point

[spark steppe]

world knows all persistent levels? thought there could only be one at a time?

[spark steppe]

why did i ask... 😄

[forest sable]

lol

1 sec

[spark steppe]

yea you might flip at some point, can you print the rotation value to screen and see if it suddenly goes from around -180 to 180?

but then it would also happen on first run.... really weird

[forest sable]

The Yellow Box Ways the bloblem

[forest sable]

Thanks a Lot for helping me out ❤️

[odd ember]

all that for a can

[forest sable]

Yup xD

Look man I'm learning

[odd ember]

it's all good

[spark steppe]

well i like that feature, was going to try to reproduce it. glad you sorted it out

now i can copycat the nodes 😛

[bright frigate]

ok so seems when the time is in single digits (e.g. 09:05), it's going to print 9: 5 in the widget since of course, these are just raw numbers plugged in. What can I do to concatenate a 0 to the strings that are < 10?

Or am I supposed to have some sort of defined formatted counter thing I don't even know how to explain

[wraith bay]

I fixed what I wanted to do. Since im new to Unreal im still learning, essentially I made a timer for my game, but the starting area wasnt meant to have a timer. Since I made the timer in my player blueprint, i was dying after 30 seconds of being in spawn, I now moved the whole timer shit to another bp

Thanks anyways boys 🙌🏻

[spark steppe]

there are some nodes which take time as input and have a text output

maybe one of them suits your requirements

[open rose]

Thought id ask again because I'm still having the issue, I was wondering if anyone knew a fix to this problem, its been bugging me for a few weeks now but has gotten that bad in the past few days due to the addition of a car, I really need to fix this as its so easy to cause and effects gameplay hugely, if anyone can help, a response would be really appreciated, and thanks to anyone who even just reads this.

[dawn gazelle]

If you're using an int to represent the minutes, then when you're converting the int to text, you can click the little triangle at the bottom to get some additional settings. You'll want minimum integral digits set to 2, then it'll always output an extra leading 0 if necessary

[open rose]

Also not sure if this affects the issue I'm having but its to do with rotation so I thought id attach it, this is how my looking up and down works, idk if this is a bad way to do it or not though: (also oddly enough i tested it and the cast always returns as false even though the cast works perfectly, not sure if that's good or bad)

[bright frigate]

Ah, excellent! Thanks. I had opened the nodes up earlier but didn't read that lol my bad

[open rose]

better example of the issue:

[earnest tangle]

This is pretty hard to say, but if it gets screwed up when you enter and then exit the car, that seems to suggest something in your pawn is not reset correctly

For example if you have any roll rotation that could affect it because character movement comp and the mouse aiming logic hates roll and doesn't make any attempt to work correctly if it's not 0

[open rose]

is there a way to reset it after exiting the car? also ive had this issue before when my character walks down a slope, but its not happened for a while so idk if its fixed, but the main issue is the car, so if you know how i can make it reset itd help a bunch (also sorry about the ping i forgot to click the un ping button)

[earnest tangle]

There's no real "reset pawn" function so you would have to figure out what value gets messed up and just manually set it back

If all else fails, you could try destroying the old pawn and spawning a new one

[open rose]

the issue with respawning my pawn is im pretty sure itll also reset all ammo and health values, and i know that the pitch is the value that messes up, i just dont know how to make it set to 0

i have this on an event tick but i feel like it does nothing

[earnest tangle]

Is skeletal mesh the root component?

Because most likely the root is what's got the wrong roll if that's the issue

[open rose]

ngl I'm not sure which one the root is, I'm assuming the capsule component but I'm not sure (also idk why i have 2 meshes, the skeletal mesh is the only one that does anything)

sorry about me not knowing any of this btw, im really new to unreal

[earnest tangle]

Yeah root component is the component which is the "topmost" one in the component tree, so yeah the capsule in this case

[open rose]

i think resetting the roll of the capsule component every tick worked, not too sure tho, ill test it more, thanks for the help

[stray lodge]

Ok folks, I got a super dumb question here. I'm fairly new to UE and I'm just trying to do a simple thing here which is - debug/print string when a key is pressed.
I have tried changing blueprint classes, used Input mapping, but nothing works. There is nothing in this project except this BP which is a component of a plane. Hello gets printed when I start the game but no key input is being printed.

[earnest tangle]

If that fixes it, you most likely can just do it once when you exit the car and not on tick

[open rose]

nvm its broken again, it fixes it the first time you get in the car, but if you keep getting in and out it slowly breaks, its really weird how it fixes it the first time but still breaks, also it makes my game drop to 0 fps when getting in the car and spawning for a second

[harsh hedge]

How do i disable blueprint temporarly i use blueprint just for prototype for c++?

[dawn gazelle]

What blueprint is this code in?

[stray lodge]

it is under Pawn class, there is nothing else in this BP. I tried using Character class too but same issue.

If thats what you are asking

[dawn gazelle]

So I'm guessing you placed this blueprint in your level, yes?

[stray lodge]

Yes

[dawn gazelle]

Ok, did you set it up so your player posesses it?

[stray lodge]

I'm sorry, I didn't get it.
There is no player in this project yet. I was working on another project where I was having issue and thought maybe other BPs are causing the issue. So I started with a fresh blank project, added a plane and directional light, created this BP and attach it to the plane. I'm sure I'm doing some basic mistake here.

[wraith bay]

Is there a way to hide a hud bp on specific levels?

health bar ^

wait i can make a boolean right

[dawn gazelle]

There's always a player. Whenever you start a game as a client, a player controller is created which is what takes your inputs and does things with the game. It doesn't exist as an actual character or pawn in the scene, but it is still present. Player controllers can possess pawns or characters which will route that player's controller's inputs to the pawn or character they are possessing.

When you set up the inputs on a pawn, all you're doing is basically saying "if I'm possessed by a player, and they press these keys, do these things..." Inputs are not automatically routed to any pawns or characters.

To get your player controller to possess your pawn quickly for testing, you can select your pawn in the world outliner in the top right of the screen, and when selected look under the details tab, and find the "Auto Possess Player" and select Player 0.

[open rose]

It reduces how much the issue affects the camera, but after getting in and out of the car the issue gets back to how it used to be, so setting the X of the capsule doesn't fully fix it, but the capsules rotation is the issue

[stray lodge]

Thanks @dawn gazelle for the quick explanation! I really appreciate it. I tried but I'm still having the same issue. Created an Empty Pawn, attached my BP to it and changed the "Auto Possess Player" setting as you said, still I had the same issue. I have also added ThirdPersonBP feature pack, changed setting in the ThirdPersonBP's setting but still the same issue.

[terse latch]

I was messing around with max limits and noticed something. tho it might be obvious but the numbers like to snap to the limit at a certain point. So is there a way to tell where the limit is before overflow? like with floats I hit the flow limit I think of 9223372036854775808 (overflow?) so here are a few thought i hope to get working.

1. take the idle game idea and have insane values.
   or
2. set a cap limit but I am not sure where that limit is before it jumps to the overflow and breaks alot of things.

[dawn gazelle]

Attaching a blueprint to another actor doesn't route the controls to the attached blueprint. In your scenario, your controls would be routed only to the ThirdPersonCharacter

[terse latch]

I thought that which is odd as that is not the limit i am getting. Unless there is is something that is a 64bit int somewhere blocking it. hmmmm welp going to mess with numbers and try and mess with the numbers.

[stray lodge]

YOU ARE THE BEST!
So basically I will add a pawn and edit its on blueprint for Input. right? My understanding was I could create new blueprint and attach it to the pawns or characters and that will work just fine.

[dawn gazelle]

Not really no, as it doesn't make a lot of sense attaching a pawn to another pawn or character. What is it you're trying to accomplish by doing so?
(I should say, there are cases, but usually it'd have to do with putting a character inside of a vehicle as an example)

[stray lodge]

Reusability. Create a blueprint with various variables which can be used by different pawn or character with some custom tweaks.

I know that's not the way, I just thought maybe that was possible.

[muted halo]

Hey guys does anyone know how to change the duration in seconds into FPS? Im trying to get a print string to print every frame instead of second

[meager spade]

I know it's possible in cpp since you can provide a key to the debug message. I don't think it's possible in BP

[muted halo]

Ah okay thanks @meager spade Im trying to get my string to output 30 times every second and doing 0.033333 will cause problems for me, later on cause its not gonna line up exactly

[meager spade]

If you can do it in cpp just provide INDEX_NONE in the first parameter in printdebugmessage

[bright frigate]

why is my timeline jumping from 0 to 12 and then carrying on as normal?

I'm doing a separate timeline for setting the seconds because I can't seem to figure out the maths from the original timeline maths for hours and minutes. So a jank thing once again, but it works perfectly fine if every minute = one second, but if I double it (every minute = 2 seconds) then it goes out of sync like this

[odd ember]

are you doing some kind of rotation

[bright frigate]

just updating the hours, minutes and seconds fields in the sun position bp

right now the curve is set for 2880 duration (2 seconds per minute, 1440 minutes in 24 hours, so end point of 2880 has value 1440).

If I set the duration to 1440, so every second = 1 minute, then it's all fine

[odd ember]

make your hours be in floats

I'm pretty sure it's because you're dividing integers

which can't be rounded

[bright frigate]

but the inputs have to be ints

the sun bp only takes ints

[odd ember]

I don't see any issues with you truncating minutes from float to int

[bright frigate]

sun and sky takes floats and is a lot easier, but it has no connection to sky sphere which means night time is completely dark which is why I'm stuck with this version of the sun bp

[dawn gazelle]

Not the greatest way...
You have a few options:

1. Create a "base" blueprint (can be character, pawn or whatever you need) that contains everything you could possibly need, including any functions, inputs, variables etc. Once created you can create child classes of that blueprint and override anything you need to such as inputs and functions, and you can then create child blueprints of those blueprints which can override things further. Along the way you can add any additional variables and functions in children as well.

2. Create and use Actor Components - these can be added to any pawns or characters, and can contain functions and logic in them, but not direct inputs - you would have to route the inputs from the pawn/character to the component in order to use its logic, or read values from the component in your character.

3. Attach Actors rather than Pawns or Characters Pawns and Characters are meant more to be moving objects in the world that can be possessed by players and AI. Actors can be objects that are not possessed. An example of this could be something like a gun - when you attach the gun actor to your character, the character could hold the gun appropriately, and when you press the "Fire" button it passes info to the attached "Held" weapon, and then the weapon can then do its thing. Similar to the Actor Components, you'd have to pass values back and forth between the attached Actor and the character.

[bright frigate]

then it just makes the seconds also move at 1 second per 2 real world seconds

i.e. minute 1, second 1, minute 2, second 2, etc.

[odd ember]

it's not going to change your logic

[bright frigate]

and so that leaves the sun still moving in a jarring way

[odd ember]

but it will show you the error

[bright frigate]

this is how I understand it so far:
if I have one minute change for every 2 real world seconds
then I need to change the seconds field from 0-59 within 2 real world seconds

this is why I used another timeline to span 0-59 within 2 seconds

it works if my first timeline (for hours and minutes) is using 1 second as 1 minute
but that's too fast
so for 2 seconds for 1 minute, it goes out of sync

ever so slightly

so the sun is kinda moving back and forth

hope that made sense

[odd ember]

do you want it to work

[bright frigate]

as I mentioned, if I hook up the minutes to seconds directly it does not work

[odd ember]

I'm not asking you to hook up minutes to seconds

I'm saying make your hours a float value

[bright frigate]

so what did you mean here

[odd ember]

that you are already doing it

[bright frigate]

from which node?

the timeline is putting out float until I divide it

which gives the int

[bright frigate]

you want me to make that into float and connect that to the seconds?

[odd ember]

no

read what I said

or actually just put down breakpoints and see where it breaks

that will find the issue easier

but it's almost certainly a rounding error

because you divide

and only use the whole number

[bright frigate]

but there is no problem with the hours and minutes part of the code

[odd ember]

so where is the code with the seconds?

[bright frigate]

sorry I thought I took the shot properly but I missed it out

that timeline is for separately calculating 0-59 within 2 seconds, which is jank I admit

[odd ember]

yeah so it is a rounding error

you should be calculating alphas inside of timelines, not real values

then multiply the alpha with whatever number you need

then you also only need one timeline

[zenith trout]

how can i make an event repeat?

so repeat always

[odd ember]

a timer @zenith trout

[zenith trout]

huh

how should this work

[odd ember]

drag the red pin out > create event

then pick the event you want to repeat

and look up google how it works otherwise

[bright frigate]

any suggestions on what kind of an alpha range I should use? Regular 0-1?

the issue really isn't the return values it's the duration that is causing my head to spin lol

[odd ember]

0..1 is the alpha range

[bright frigate]

giving me high school flashbacks where I would get headaches from these time-calculations in maths classes lol

[odd ember]

the duration and the last keyframe are probably not synced up either

if I had to guess

[bright frigate]

I tried both enabling disabling use last keyframe and it didn't seem to make any noticeable difference (except when duration was set for 1 minute per second)

[odd ember]

your last keyframe should be set at the end of the duration

[bright frigate]

yea it is

[odd ember]

how long is the duration

[stray lodge]

So, basically I have to create a pawn or character which has all the inputs or base functions, variables. Then create child blueprints or actors who can access those inputs and do something.
Now, going a bit off topic and I'm not sure whether this is even relevant to this. I used to create something like GameManager in Unity where I would keep inputs or global variable like say health or player state, etc which were further access and set by other classes. Now, I see UE has PlayerController which I can create with custom GameMode. Is it an ideal way to create all the inputs or other variables in PlayerController Blueprint which is further accessed by a player or npc character or any actor component?
I know I'm jumping guns here but just want to have clarity about the ideal practice with UE and BPs.
Thanks @dawn gazelle you have already made my day, not sure how long would I have been stuck on this. I really appreciate your help in this!

[bright frigate]

2880 real world seconds

I'm now thinking how to map the alpha range to the 24 hours/minutes/seconds

[odd ember]

you multiply the alpha value

and handle calculations outside of the timeline

or even better, lerp values

that solves your issue with truncating results

[bright frigate]

24 hours = 1440 minutes
120 seconds = 1 game hour (if I want 2 seconds to be 1 game minute)

[odd ember]

use lerps, to lerp between (hopefully) integers

that should work

[bright frigate]

so no timeline?

[odd ember]

so that will be 3 different lerps from the same alpha

no you need the timeline to supply the alpha

[bright frigate]

ok yea

[odd ember]

actually that's a lie, you'll need 3 alphas. but not to worry, you can create them all inside the same timeline

so one for hours (in real seconds), minutes (the same), seconds (the same)

so one hour should be 120 seconds in the timeline, a minute would be 2 seconds, and a second would be 2/60, which is just about 2 frames.. about 0.033 second

[bright frigate]

does this make sense

[odd ember]

yeah but why would you want to do it like that

[bright frigate]

I dunno just the most obvious thought in my head lol

[odd ember]

I just told you

try to lerp ints

[bright frigate]

I did this just before you wrote your new message

[odd ember]

ok ints aren't lerpable

[bright frigate]

ya mon

[odd ember]

so you can do it without the multiply node

also what's with the 6 am?

[spark steppe]

that's some weird math going on there^

[bright frigate]

just want the level to start at that time rather than midnight/dark

[bright frigate]

don't I need to multiply to get a whole number e.g. 0.25 x 24 = 6

[odd ember]

so.... set the timeline to start at 0.25 play length

[spark steppe]

your float value goes from 6 to 24, why don't you just truncate the result of the timeline?

[odd ember]

otherwise you won't ever get to see 00:00 to 06:00

[bright frigate]

I was thinking of going from 0,0 so that I can use the same track for minutes and seconds rather than those starting from 0.25 as well

[bright frigate]

For this I did this bit of genius 😛

the original only plays once and then goes to the new one for a complete 00:00 to 24:00 loop

i know TOTAL JANK

[spark steppe]

actually, why do you use a timeline at all?

[odd ember]

just... why

[bright frigate]

😂

just you know

16 hours awake

have to do something

[odd ember]

it's like you had a resevoir of clean water next to you and you decided to walk 5 miles to get water from a dirty river

[meager spade]

😂

[bright frigate]

that's missing out the obvious fact that I don't have feet and am stuck in a spaceship

[spark steppe]

don't question my life decisions 😄

get some sleep maybe?

like a lot

[bright frigate]

like I don't have super well rounded knowledge so I'm working with what i'm seeing in tutorials/whatever I know etc.
if someone offers a better solution then that will add to my knowledge

[odd ember]

there's a reason people say start small

[bright frigate]

I try to but these days I'm having night terrors so it's kinda rubbish quality sleep

[bright frigate]

isn't this small enough

[odd ember]

if you're in here asking questions every single step of the way? no

[spark steppe]

yes

i think you are overengineering your problem

you want to map realtime to gametime, right?

[bright frigate]

I'm not asking every single step of the way I'm asking when I'm encountering problems,

[bright frigate]

I want 2 seconds to be 1 minute in the simplest words

2 real seconds to be 1 game minute

[spark steppe]

gametime since launch * 30 = ingametime

done

[odd ember]

this is like the second or third step where you're asking. if you're sleep deprived it's not helping either. nobody is going to do math well at that point

[meager spade]

https://www.youtube.com/watch?v=qWSu2C4ANE4&list=PLDnygpcOYwFW2XtNyiandrLDG__OAZs7Q&index=6 This is the video I got my in game time from. Honestly don't remember exactly how he did it but you should be able to scim through it and get some knowledge

[bright frigate]

I am primarily an artist so all of this is a lot more gnarly for me even if I understand the theory fairly well. But working with game engines means one needs to become very familiar with someone else's logic (the people who wrote the engine, the ones who developed the API and rules). Considering how intricate the engine is, there are a lot of 'rules' to playing the 'game'-engine, pun not intended

[spark steppe]

that issue is unrelated to the engine

[bright frigate]

there was a time 15 years ago I could do all this in C++ without much of an issue, but again, that would be me writing from scratch and setting up everything myself. This is a different scenario

[odd ember]

the rules are very similar between engines, and between most programming. this engine is no different. the big difference is that it unfortunately makes some end user friendly concessions that end up teaching people without the knowledge the wrong things

[meager spade]

Check the video I sent, he doesn't do some stuff in a very good way but for the real time to ingame time stuff you should be able to get something

[bright frigate]

thanks I'll check it out

[spark steppe]

as said, thats a simple multiplication and you have your ingame time

idk why you make a big deal out of it

[bright frigate]

how am I making a big deal out of it lol

I'm just asking for feedback / better solutions that's it

[spark steppe]

you came up with a timeline

😄.

[bright frigate]

I didn't come up with a timeline

I watched a simpler tutorial which used it

[spark steppe]

3 timelines 😄

yea another problem with that end user friendly engine is that there's a bunch of tutorials which teach crap

[bright frigate]

and I couldn't figure any other way to make the bp plugin work, the other solutions of my own I tried on tick for example would kinda sorta work but not really

[bright frigate]

just jank to go through it quickly and see before I optimise things

[spark steppe]

or people don't understand why the person is doing something that way

[bright frigate]

the tutorial was fine because it was just like a proof of concept if you will. It had no real requirements like I do where I want the time to be slower and I want the seconds incremented as well

the original tutorial had the speed quite fast, 24 seconds for a full cycle (basically mapped 1 second to 1 hour) which means the sun was moving fast enough to not be jarring

I only realised I needed to increment seconds as well once I slowed everything down to the usual pace of day night cycles in games

I would use the sun and sky bp that uses solar time as a float value, so just 1 value making it really easy and simple, but for some bizarre reason Epic decided it won't use the sky sphere and doesn't take any, which means at night there are no stars and it's pitch black, so I can't really use that

[spark steppe]

you can use a night scene capture for the sky sphere

they decided to not force anything on the developer

[bright frigate]

no I mean the sky sphere does not work together with the sunandsky bp at all

they don't communicate and can't

so if I recapture the sky sphere, it doesn't recognise any sun that it can use

because the sun in the sun and sky is nested within the overall plugin, which the sky sphere can't see

the older sun bp that I'm using right now does work together

[spark steppe]

i have no idea what you are talking about

is that a specific plugin or example blueprint?

[bright frigate]

ok so there is a plugin called "bp_sun position"

this will work with the sky sphere and directional light in your world

there is another plugin called "Sun and Sky"

I believe this is the 'new' one

[spark steppe]

both from epic?

[bright frigate]

default in the arch viz template

[bright frigate]

yes

but this one has a directional light and another thing nested within it, as components

but it does not work with the sky sphere

so if you want starry nights, you have to use the older one

[spark steppe]

well, you can't take anything out of an "asset" and expect it to work the way you want it to

[bright frigate]

the older one uses separate values for hours, mins, secs
the newer one has one value called solar time, which is a float, from 0.0 to 24.0

so it incorporates mins and secs within that one value

[spark steppe]

you should rather try to understand how those blueprints work, rather than trying to adapt your game to their requirements and limiting yourself

[bright frigate]

for this new one, it's really easy to just hook up to event tick, delta seconds x whatever speed I want it to increment and plug it into solar time more or less

[bright frigate]

there is almost zero material out there for me to read or understand in the first place

there is literally only 1 tutorial which I used and that is the timelines one

for the older sun position bp

[spark steppe]

the sunposition is just rotation around the world, isn't it?

[bright frigate]

yea but it's geographically accurate

with lat, long, north offset, timezone, etc.

location

date

everything

and I need those

[spark steppe]

😄.

[bright frigate]

so you see :p

cause the reason is that I've made a place as accurate as possible, a real place, as it was in a real point of time in history

so the lighting needs to be correct as well for that time, which the bp offers easily

[rough blade]

Is it possible to change an actors movement mode in runtime? Whenever a player possesses an actor id like to switch it from navmesh walking to walking but as far as I can tell it doesnt update (same weird interactions during navmesh walking)

[spark steppe]

sure, just set the movement mode on the movement component?!

what kind of weird interactions?

[rough blade]

Thats what I do - walking through walls, vehicles freaking out when they stand on them, ect. none of which happens during normal walking

[spark steppe]

you could try to disable the component before setting the mode, and reactivating it afterwards

but this somehow doesn't sound like an issue with the CMC (tho im not sure)

[rough blade]

hmmm ill give it a shot - thank you!

[spark steppe]

get array A, set array B and plugin the array a as input of the set node

what's the data type of the array?

they should just copy over to array b

oh

you want to compare 2 arrays, sorry, i did misread your question

iterate over one of the arrays, and check if the item exists in the other array, if so add it to an temporary array which holds the duplicates

there's the "contains item" node for arrays which you should use for the check

[trim matrix]

anyone knows why in packaged when trying to change resolution in fullscreen my screen flickering?

like trying to set resolution but cant

should i try with command instead set resolution node?

[zenith trout]

what should i do?

[spark steppe]

you should explain what you want to do

because the node setup doesn't really provide any informations

other than that you want to set somethings location when something got hit

[zenith trout]

if i hid the obj (pad) i want to change th location of the "blockrunter"

[spark steppe]

and blockrunter is what? some other actor?

[zenith trout]

yes

[spark steppe]

do you have a reference to it on your pad blueprint?

[zenith trout]

no

[spark steppe]

does blockrunter exist multiple times or only once?

[zenith trout]

once

[spark steppe]

then you can use a get actor of class node

and set the class to blockrunter

and use the output for your target

[zenith trout]

thanks!!!

[winged sentinel]

i cant get my replicated health to appear on my hud, it never updates. How can I fix this?

this is my health component

could i just make health a rep notify or something and cast to my hud to change the text

it does in fact change on the server correctly because this shows my the correct damage being taken

[dawn gazelle]

Yep

[winged sentinel]

hm okay is that efficient tho? I was always under the impression that casts are expensive

[dawn gazelle]

Casts are only bad once you get into the 100000s of them per second, and even then, it's minimal impact.
If you're worried about it, you could also set up a bind which is effectively making it update the value on tick - which again, takes literally hundreds of binds to actually see any kind of performance impact - so long as you're not doing some complicated math with them and just using them to display the value, then it's not really a problem.

[winged sentinel]

i see thank you for that information

[dawn gazelle]

You could also do the reverse - have your OnRep call an event dispatcher which your UI binds to - then you only have to cast once to get reference to the object where your health is and bind to the dispatcher - the event can then update your health value in your UI

[winged sentinel]

i will try what you mentioned above as this doesnt work

i have it inside of my rep nootify function for health

is it maybe an issue with how im replicating it? do i have to make it run on client as well?

[prisma stag]

Curious as the why this isnt working. I added a breakpoint and it executed but the Item Quantity never changes.

~Thanks

[spark steppe]

the foreach loop might give you a copy, not a reference to the real struct

[prisma stag]

Ah, so its not setting the actual value that I need to be set.

[spark steppe]

actually you are filling the array with copies

[prisma stag]

Darn. Is there a workaround to this?

[spark steppe]

make a function where you pass the struct as reference, and call it for each struct

but you have to set the argument explicitly to reference for it to work

at least that's the cleanest way i could think of right now

[prisma stag]

So the function would be what is the loop body? Then the input to the function is the struct?

[spark steppe]

no, you would screw of the loop + array

it would only do the addition and set the result

[somber crypt]

Anyone had any issue when you add a startup movie? Game runs perfectly without a startup movie. When I add the UE4 logo movie the game starts and....
Assertion failed: IsInGameThread() || IsInSlateThread() || IsInAsyncLoadingThread() [File:Runtime\Slate\Public\Framework/Application/SlateApplication.h] [Line: 225]

TheGame!FPreLoadSlateWidgetRenderer::DrawWindow()
TheGame!FPreLoadScreenSlateSynchMechanism::RunMainLoop_SlateThread()
TheGame!FPreLoadScreenSlateThreadTask::Run()
TheGame!FRunnableThreadWin::Run()

[prisma stag]

Im still a little confused. As you can see in the picture, the function is only called once so there is no reference to input.

[spark steppe]

you would make another function which gets called for each struct by the one with the red arrow

however it looks like your logic is somewhere earlier messed up, as i think you could avoid doing it for each item type

[prisma stag]

Hm. I cant see where as each struct has its own item quantity that needs to be set.

Im just trying to avoid this.

[spark steppe]

that's why you should make a function which takes the struct reference as input

that function only does your addition and set the value to the struct

you'll still have a function call for each struct, however it's not as messy as what you posted 😄

[prisma stag]

Oh, that makes more sense. Sorry a little tired 😂. Let me give that a try and then see how to loop the function.

[spark steppe]

no loop for you 😄

[trim matrix]

Is it possible to reference a material inside of a blueprint, if so, how would you do it?

[spark steppe]

you would create a dynamic material instance

[obtuse herald]

To reference a material, you need to create a 'Dynamic Material Instance' in runtime and set it as material on your mesh.

Or you use 'Material Parameter Collections'

https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphics/Materials/MaterialInstances/

https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphics/Materials/ParameterCollections/

[trim matrix]

What if it is a post-processing material though, it would not have a mesh.

[spark steppe]

you know you can put <> around links so that it wont create previews?

[obtuse herald]

oh really?

[spark steppe]

try it, and edit them 😛

[obtuse herald]

damn

thanks!

[trim matrix]

I have Player Blueprint, and the camera has a material post-process material, and what I am trying to do it reference it so I can change the parameters.

[obtuse herald]

like that

[trim matrix]

Alright, I will try this out, thank you so much!

[prisma stag]

You're not talking something like this are you?

[spark steppe]

yes

[prisma stag]

oh

[spark steppe]

but you have to set that input to reference

in the details

actually you are passing a copy, so it shouldn't work

[prisma stag]

It works now.

[spark steppe]

but it shouldnt 😄

[prisma stag]

😂

the many wonders of coding.

[spark steppe]

until it breaks

i would still set it to reference

just to be safe

[prisma stag]

Yea, once I ticked the Pass-by-Reference, it started to work.

[spark steppe]

it's one checkbox, you can click it, DO IT

ah i see

well ok

[prisma stag]

Ok, so now it makes sense 😂

[spark steppe]

yes

[prisma stag]

Thanks for the help.

[obtuse herald]

also maybe you want a loop instead of pasting the same function 10 times >.>

[prisma stag]

Oh thats true, I could just create an array of the structs, and then the loop body would be the new function. Let me try.

[spark steppe]

no

[obtuse herald]

yeah, don't forget to use 'get (by ref)' instead of the normal loop element

[spark steppe]

your array wouldn't hold references

[prisma stag]

aw man, back to this.

[spark steppe]

unless you can set arrays to hold struct references, i'm not sure about that

[obtuse herald]

pretty sure they would, you just need to get them by ref

[prisma stag]

Which we set for the input of the function ^

Ill give it a try and let ya know.

[spark steppe]

but if that works, you can screw the function you made, and return back to your old setup 😄

just with references then

i was under the assumption that arrays cant hold struct refs

[prisma stag]

No, you're right.

[static charm]

they can hold object references

[spark steppe]

yes

[static charm]

not sure about pass by references

[prisma stag]

Doesnt seem so.

So is there a way to loop the function for each struct or is it just create a long train?

[spark steppe]

yea, don't hold them in separate variables like that

make a map with name as key and struct as value

[prisma stag]

I have tried this before, but found no documentation on how to access each structs value.

[spark steppe]

then i wonder where you looked at 😄

[prisma stag]

. . .

[spark steppe]

https://www.youtube.com/watch?v=cf25ekO-AFs

[prisma stag]

Oh wait. OMG

I didnt even watch the video yet.

🤦‍♂️

Ok, so I havent put any values in the struct for the map variable, but would this work for what I want?

[obtuse herald]

interesting, it says it's by ref but it isn't

so nope, you can't loop it.

[prisma stag]

oh

[obtuse herald]

or that

[prisma stag]

So then what could I do?

[obtuse herald]

when you're using a map, you can just set them by name

[prisma stag]

I need this to happen for all of them.

[obtuse herald]

like that

The map hold the names (key) and their corresponding structs (value), and since we're looping through every key, we can change the value of every key (without needing a ref)

[prisma stag]

Oh, so we are changing the value with a copy, then using the add, to override the values for that key?

[obtuse herald]

exactly

[prisma stag]

Ahhhhh.

So now I wont need a struct variable for each item, but rather add it to the map, and it will loop and override by itself.

[obtuse herald]

Yeah

[prisma stag]

Gotcha. Now I just need to figure out how to bind certain struct map values to a widget.

[dawn gazelle]

Your health component is on your player controller?

[winged sentinel]

No, it’s on my regular character. I casted to the controller because that’s where I reference my widget

So I made a custom event that checks the health and prints it. I made on that is on a replicated rpc and a non replicated custom event. From there I see that server is returning the correct health, and that client is returning 100 health still even if my character is hit. Is that something to do with it?

[dawn gazelle]

That's not how casting works. Casting is taking a less specific reference (like an Actor) and making it more specific (like your character) so you can access the functions and variables within the more specific class. It doesn't convert between classes, so you can't cast a reference that would be your character to your player controller.

On the OnRep, do a "IsLocallyControlled" branch. On the true, get the owner, then get the owner of that, then cast to your player controller and proceed as you were... Pretty sure it'll work from there.

Eg.

[mossy vessel]

How do you put bps in different sections like this?

[obtuse herald]

via category

(details panel of bpf)

[last abyss]

additionally you can use ' | ' to subcategorize, for example; UI | Text or; Stats | Resistances

[gray chasm]

Is there a nice way of a having a 'marker' on an actor? Like, for example, with a vehicle, I want the character pawn to spawn next to the vehicle when they exit the vehicle. Currently I'm just using an offset, but its fiddly be nice to be able to visually edit the various spawn points.

[tame haven]

I hope i'm not in the wrong thread - if i am then sorry. I have a little problem with widgets. I'm adding widgets to main widget via User created category (i'm using widget switchers and i thought it would be the best option). Widgets added this way does not contain any information. They are visually okay but progress bars are not filling up. Does someone have any idea how to make it right ?

For clarification: When i add widget via normal "add to viewport" they are working perfectly fine.

No help needed anymore.

[opal totem]

is there a way to get a random item in a Set?, similar to the way you would get a random value from an array (generating a random index, for example)

[gray chasm]

? Can you not just use RandomIntegerInRange?

[obtuse herald]

Scene Component?

[gray chasm]

oh perfect~

I didn't realize that was a thing.

[obtuse herald]

you're welcome

[faint pasture]

Scene component or a socket on the mesh

[opal totem]

@gray chasm I know I can do that and access an array, to get a random element in my array. However I was wondering if there is an equivalent way to do the same thing with a "Set" instead of an array. I can convert a Set to an array. but I was hoping to avoid that step and be able to somehow randomly access the Set, and get a value.

[earnest tangle]

@opal totem if there is a node to get an item from the set by index, you just need to create your own function which generates a random number between 0 and set length - 1, then get the value from the set

[gray chasm]

There isn't. Weirdly, despite the fact it's implemented in TSet (ElementType& operator[](FSetElementId Id)).

uh.... I guess you can't without writing some C++ to pull the index out. nfi why it's not part of BlueprintSetLibrary.h

I think 'To Array' is as good as it'll get in pure BP.

[opal totem]

I appreciate the feedback, not going to spend any more cycles on it. 🙂 arrays will work fine.

[lucid lynx]

Is there a way to clear a mesh or set a mesh to null?

Specifically trying to clear the actual mesh, not just set it to hidden.

[lethal yew]

yes, call setmesh and just don't add a reference, leave it blank

[lucid lynx]

lmao, thanks. dunno how I missed that.

[jovial prairie]

hey how do i make it so the buttons switch when i click on them? Atm they just print string for debugging...

couldnt find any good tutorial for what im trying to make

The buttons are being displayed on this tablet and here i would like to switch between the options

[opaque blade]

Switch in what way? Change color / texture?

[jovial prairie]

like in going to the next page and back

like an option menu

[opaque blade]

You can look into https://www.youtube.com/watch?v=7Mbe-hQl0Yg

There are tons of ways of doing it though

[jovial prairie]

https://www.youtube.com/watch?v=RZlCqZhI9Nc&t=46s&ab_channel=Uisco

atm tryign this but idk

but ill check that one for sure

[faint pasture]

I use an enum driven State machine.

On button press...
UpdateUI(UIStateEnum)

Then I swap widgets around etc based on the new UIStateEnum

[jovial prairie]

i made this

[feral shale]

Hey guys, I'm having an issue that I cant really get my head around.
I want a certain object to change material etc. on every rendered frame, so normally I would just put it in the tick function of my object and then just render the sequence out using the movie render queue, however because I'm using subsamples in the render preset to give me better raytraced results, the ticks are firing on the sub steps(16 substeps pr. frame) - is there a way to make a function thats fired every frame and not on the substeps?

[lethal yew]

interesting problem....

i don't know, but as a worst case, could you change your logic to take a parameter for how many substeps between changes?

[spark steppe]

have you tried to set the tickrate to match your frame rate?

[feral shale]

Not running fixed framerate, since there is no "fps" when doing the pipeline render as far as I know

[spark steppe]

hmmm, i thought it would still be framerate bound even when rendering for movie

then i would just add an integer which increases to 16 and gets reset then while switching the material

[feral shale]

I mean, I think all internal things are done with a calculated tick, but as soon as temporal samples are above 1, it fires multiple ticks to get everything to blend together

[feral shale]

What I've been doing so far, but it doesnt work with temporal sampling. So I guess I have to get stray away from using temporal and only spartial

[spark steppe]

ok, i dont know about that stuff, maybe someone else comes up with a solution

maybe virtual-production or something is a better place to ask

[trim matrix]

How to run UMG widget on the plane mesh of the Actor?

[icy dragon]

As in triggering the widget to spawn on screen or spawn the widget in the world space?

[tight schooner]

@feral shale is there a way you can differentiate a substep tick from a new frame tick? Like is there some frame number or timestamp you can get to make that distinction? If there is, you can maybe compare it to the prev frame data or something to produce a boolean and branch the logic off that.

[feral shale]

I found out the issue I was having was temporal substepping, no matter how I wrote my code to compensate it would also blur the frame with the one before and one after

[lethal yew]

Are you sure? It seems weird that it would work for one but not the other. Have you got the frame count right? It's temporal * spatial samples.

[feral shale]

Spatial samples doesn't fire tick

only temporal does

atleast thats my conclusion from my testing

[lethal yew]

Ahh ok yeah that would make sense. Was just trying to think why you would get blurring before and after still

[feral shale]

I think it's down to how AA works in UE

Temporal sampling where stuff changes from frame to frame will always introduce bluring between the two frames

[lethal yew]

Presumably you have disabled post process motion blur and temporal aa?

[feral shale]

yep

[zenith trout]

how can i make this repeat?

[earnest tangle]

Repeat what?

[zenith trout]

the event so that it always moves upwards

[earnest tangle]

Put it on tick

You can also use a timer, but if you want it to smoothly move, then putting it into tick would probably make most sense

[late cave]

What am I missing here? Why isn't Unreal showing me the real values? Just hovering on the lines doesn't work either...

[earnest tangle]

Because the BP debugging functionality is finicky

and sometimes just refuses to show you anything useful

[dim sun]

hey quick question, I come from Unity and was wondering how to reference a Camera (or any other object on a level) directly from a Widget, without having to have a GetAllActorsOfClass. Is that possible?

[dark crow]

GetAllActorsWithTag 💯

[surreal peak]

There is a stream pinned to this channel about blueprint communication

There are few classes that more or less only exist once

Like the GameState

Those are accessible from everywhere ™

So your actor or camera can always get the GameState on BeginPlay and add itself to it as a pointer/reference

Or to a component that you add to the GameState ( to keep things more organized )

Your widget can then get that reference from the GameState

[dim sun]

nice

thank you!

[dim sun]

lol

[orchid garden]

this seems backwards... ticks are frame based, timers are time based, I get more fluid movement from timers then ticks.

[earnest tangle]

Timers are not guaranteed to run at the exact interval

Ticks are indeed frame based, the common method to address this is to multiply movement or other such values by deltaTime

[orchid garden]

nothing that works with floats is guaranteed to work on exacts, as Unreal puts it 'Floating math is complicated'.

[earnest tangle]

sure if you wanna use timers then go for it ¯_(ツ)_/¯

it is additional overhead on top of ticking, and if your framerate fluctuates enough that a single frame takes longer than the timer interval, you will get jumpy movement

[orchid garden]

and as you said, you can always use delta time to adjust with either method.

[earnest tangle]

if you're going to use deltatime anyway then there's very little reason to use timers

[orchid garden]

not true.

[earnest tangle]

yes?

[orchid garden]

again with timers you have more control then with ticks. a timer can be setup, destroyed, paused. ticks can't.

[earnest tangle]

Ticks can be paused

[orchid garden]

the only real time to use a tick over a timer to be honest is if you want to use it for something thats constant.

[earnest tangle]

What do you mean by constant?

[orchid garden]

👀

[earnest tangle]

Like.. constant movement? Like when you want to move a character?

[orchid garden]

if your using a tick to control your movement your doing it wrong.

[jovial prairie]

how do i make it so i have a slide show? or a simple back forward system?

the tutorials online dont work for what im trying to achieve

[earnest tangle]

Cool, I guess all folks at Epic are doing it wrong then because literally everything related to movement in the engine runs on tick

[orchid garden]

time line animations?

[jovial prairie]

never worked with that

[orchid garden]

their animation graph yes, which is right, character movement in the bp no, which is wrong. I like how you misdirect, good job!

[earnest tangle]

Character movement component runs most of its logic on tick

Physics run on tick

[jovial prairie]

but to be fair this is also my first day with blueprints haha

cant i just add a node that tells it to move x amount of pixels up or down?

[orchid garden]

that'd fall back to this arguement the zomg is having with me, you'd basically want to use a lerp with delta time on a timer to move by pixel. he'd probably tell you to toss it on a tick.

[earnest tangle]

you can do it whatever way you want but let's not go claiming that it's wrong to do character movement on tick :P

[orchid garden]

no your taking constants and trying to use them as examples to prove your point to use ticks for everything.

[earnest tangle]

Where did I say you have to use ticks for everything?

You're the one who said that character movement should not happen on tick, and yet the character movement component (and all other movement components) run their logic in tick

so feel free to explain how Unreal Engine is programmed incorrectly

but stop putting words into my mouth :P

[orchid garden]

omg...

twist things some more

think im done talking to Zomg.

[earnest tangle]

I'm all ears, please do explain how I'm wrong

I'm serious, I'd love to not use tick if I don't have to

[orchid garden]

im serious as well, im done being trolled.

[earnest tangle]

lol okay

[earnest tangle]

This depends on what you want to do. A timeline would be a simple way to move the slideshow at certain speeds

[orchid garden]

again. ... wrong....

[earnest tangle]

Yeah that's a valid alternative

[orchid garden]

you know, UE made those learning courses for a reason Zomg.

[earnest tangle]

I'm agreeing with you, why are you like this?

[orchid garden]

just saying...

[earnest tangle]

Saying what?

All I said was I made a suggestion to use tick, and you're just gunning for my head now

[orchid garden]

no i just pointed out you were wrong about the speeds.

[earnest tangle]

No you've repeatedly called me incompetent at this point

Is suggesting to use tick such a giant faux pas or what?

[orchid garden]

never once used that word.

[earnest tangle]

You also suggested that I was trolling because I made the suggestion to use tick

Again for no reason

[orchid garden]

no i said you were trolling me. not because of a suggestion. you keep twisting things, common thing a troll does.

[earnest tangle]

Yeah you kept attacking what I said when it was simply statements about how UE works

[orchid garden]

lets agree to disagree.

[earnest tangle]

What's your problem with that?

You don't want to know how UE works?

[orchid garden]

here we go again....

[sleek tapir]

Hello, Im new to UE and I'm just getting into Blueprints. I have a problem where when the player enters a trigger box the 1st time its firing both the enter and exit nodes at the same time. it fixes itself when i exit and enter the trigger box again, am I doing something wrong?

[icy dragon]

Go on, I love watching bar brawls.

[earnest tangle]

Yeah I honestly don't know what his problem is.... I'm just trying to help people and he just starts attacking me :P

[orchid garden]

think you got that backwars zomg.

[sleek tapir]

Do you think maybe you guys can just let it go?

[icy dragon]

Not sure how that doesn't work...

[earnest tangle]

Character consists of multiple colliding comps so one triggers entry and one triggers exit?

Not sure tbh

[icy dragon]

Don't. I want to watch a bar brawl. I'm putting the bet on the last man standing.

[orchid garden]

do a check to keep the component from double firing:

doing something similar can keep you from getting a begin and end overlap at the same time.

[sleek tapir]

I'll give it a try. Should I just put those two nodes after each then? Like i said im brand new to BPs (just started yesterday)

[orchid garden]

what might be happening is if your actor is holding something / has a secondary component, that component while walking in may be going outside of the box as your characters triggering it. If you check for something specific when something overlaps / ends overlap that can prevent you from getting both a begin and end event at the same time.

this might help, a tutorial on doors by itsmebro:
https://youtu.be/oWHHjivvK2s

[sleek tapir]

Its just the default 3d person rig. The strange thing is it was working just fine, then I added a collision box to the door because he was able to run right through it. Do you think the door is interfering with the trigger box as it runs right through it?

*runs right through the trigger box

[sleek tapir]

also thanks for the video, I'll check it out. I was cobbling bits of videos together to figure out how to do this

[orchid garden]

if he was able to run through your door it sounds like your door itself doesn't have any collision or its set to ignore collision.

[gentle urchin]

I find using tick for movement is perfectly valid, as you point out so does epic, CMC and whatnot.

[sleek tapir]

correct, so I added collision to it by editing the mesh and adding a collision box. Thats when it started acting up.

[orchid garden]

yeah the videos a full tutorial series, should help give you a better understanding so you can make your own doors or even more advanced.

[earnest tangle]

@gentle urchin yeah, it is the standard way of doing it in pretty much every game engine I've ever used and in pretty much every game source I've ever seen

[orchid garden]

so your door is triggering your trigger and firing the end event then i bet

[sleek tapir]

thats what I was thinking, however it starts acting correctly once i enter and then exit the trigger box for the 1st time. I'll watch the vids, but if this is the case, do you think adding two different trigger boxes on either side of the door would fix the problem, or is it adding complexity for nothing?

[orchid garden]

you could try.... setting the collision of the trigger box to ignore all except pawns:

[sleek tapir]

I'll give that a try

[orchid garden]

simple doors i just use a single collision box:

[sleek tapir]

yea thats pretty much how mine looks

[orchid garden]

my door never actually overlaps the collision box itself, the collision box is just slightly larger then the door for both closed and open positions.

[sleek tapir]

Yep, setting the triggerbox to only pawn seemed to fix the problem, so the door itself must have been causing the issue. Thanks for the help! and thanks for the vid!

[orchid garden]

im betting something like your handle was going outside the box 😉

[sleek tapir]

I had it enveloping the whole door by more than enough when closed.

[orchid garden]

more complex doors, like say.....

[dark crow]

Door simulator

[orchid garden]

your going to want to use the first method for begin/end events (checking against whats triggering it) rather then only using the collision.

[sleek tapir]

Yea, I'll have to figure out more of these nodes eventually. Unfortunately a lot of tutorials online seem to say 'add this node' but dont explain why or what the node actually does.

[orchid garden]

ItsMeBro is pretty good at explaining things along the way, only issue i have with his videos is they move abit fast at times 😉

[sleek tapir]

Cool, I'll try to check out several of his vids and see if they help. Thanks again for the help.

[earnest tangle]

That's interesting, I never had issues with components overlapping other components on the same actor 🤔 Good to know it can happen

[orchid garden]

seems more common with multi part static actors.

[late cave]

I'm very close to pulling my hair now, I think...

[dark crow]

Just a tip for that

Instead of Length - 1 you can use Last Index

[late cave]

huh... that's cool... still, I don't think that's why I'm missing 3 iterations 🙂

[odd ember]

is there any reason you're not using a ForEachLoop

[late cave]

yes? I want to run a very specific number of iterations, not once per item?

[odd ember]

you can also get that same behavior with ForEachLoopWithBreak

[dark crow]

What are you trying to achieve

[odd ember]

I'll be honest, I don't know how macros feel about having a variable inside of them that can be set out of their scope

[gentle urchin]

I also think you're better of temp saving the removed ones.

[odd ember]

so I would try passing the array as a parameter first

[gentle urchin]

then removing them afterwards.

[orchid garden]

are you sure the loop is only cycling 5 times? technically it should be cycling 9 (0-8)

[gentle urchin]

• last used index

[late cave]

alternative solutions are great, and I guess I'll try, but I'm super curious as to why I'm seeing what I'm seeing

[gentle urchin]

whats the incoming value?

[dark crow]

You are modifying the last index each loop, may explain it

[orchid garden]

you could very well be trying to remove a invalid index....

[odd ember]

it might be that scope thing I mentioned

[spark steppe]

what the heck is that supposed to do?

[dark crow]

What are you trying to achieve is the question

[gentle urchin]

Remove a fixed amount of indexes...

[dark crow]

That will give answers

[gentle urchin]

from a desired index

[spark steppe]

when you remove you have to run backwards on the array

[late cave]

the array is always 10 items, but a lesser number is often used... so I want to remove those which aren't (except the last one, which I always want to save)

[earnest tangle]

The array updates when you remove from it

[spark steppe]

and why do you start at 0 if you want to just remove a specific amount?

[earnest tangle]

So when you remove index 0, the index which was 1 now becomes 0

[spark steppe]

the range is quite given?!

[late cave]

yes, but I'm always only removing the indexes after the ones I'm interested in...

[late cave]

the for loop is for a specific amount, isn't it? however... yeah... it might be calculating where it ends "live" so to speak...

[orchid garden]

yeah like Ben said, run backward while removing the index with a set number of items you want to remove. rather from 0 to 8 you'd go 8 to 0 that'll keep you from trying to remove a invalid index.

[late cave]

let me throw a cache in there

[spark steppe]

don't go from 8 to 0, go from last index that you want to remove to the first index that you want to remove

[orchid garden]

well i was going by his sample pic ben

[late cave]

ok, cache worked!

my math is shit, but now I get the logic at least and can fix the math 😄

[spark steppe]

you can try hard to make this work or just pick the elegant solution xD

[late cave]

so reverse for each? but it adds a lot of nodes to count down, won't it?

[spark steppe]

also last index changes every time you run the loop body if you keep removing stuff, but im not sure if that contributes to your problem, because i dont even want to try to understand it fully 😄

[gentle urchin]

Not sure if this explains it very well but

makes sense really

Starts with array of 10, last index is 10-1, removes 1 from the array, and 9 elements remain

[spark steppe]

https://tenor.com/view/daddys-home2-daddys-home2gifs-stop-it-stop-that-i-mean-it-gif-9694318

[gentle urchin]

after 5 iterations, assuming in scope, leaves you at loop end.

[spark steppe]

cant recall if theres a separate backwards for loop or if you can just use a higher start value and lower end value to archive the same

[orchid garden]

you'd just need to make your own for loop, no backward running ones, original is:

[late cave]

I need some time to wrap my head around that one 😅

Mine does seem to work now though...

[orchid garden]

there is a reverse for each, just not backward for loop. only difference would be you'd subtract instead of add, and check to against first index instead of last index.

[gentle urchin]

Generally prone to errors when removing from an array you're using as the loop condition moving forward. Many pitfalls. fewer going backwards

Still i wonder if this dynamic approach in general has a gentler solution to it, but that's your call in the end

[late cave]

I totally get that, but note that I'm not increasing the index that I'm removing! I'm always removing the same index in this case.

I'm also not looking at any values in the array, because I don't care

[gentle urchin]

True, and i can only assume you validate the incoming index aswell

[late cave]

yes! (from a switch on an integer, always between 0 and 9)

[gentle urchin]

right, so even when starting later, you'd just quit sooner, so no biggie

[late cave]

well this was fun, thanks everyone! 🙂

[tame stream]

What's the best way to manager character customisation? think runescape character customisation kind of stuff, what i mean specifically is being able to change your legs, torso, stuff like that. I don't understand how you can split mix body parts to make a proper character.

I didn't explain that well. I'm just not sure how to seperate a character into seperate sections, torso,legs, arms etc

[spark steppe]

https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/WorkingwithModularCharacters/

[tame stream]

modular, thats the word I was after! thank you so much

is modulation a cause for performance issues? i imagine it would cause issues instead of being one solid mesh

[dark crow]

I wouldn't worry about it, sounds so minimal

[spark steppe]

the docs go into performance

[tame stream]

it's a VR project, so anything minimal tends to make a difference i find haha

[spark steppe]

scroll to the end, there's an overview

[tame stream]

depends how many players are in the area

[spark steppe]

also with mesh merge you pretty much get the same performance as a solid character mesh

[tame stream]

good point

thank you so much for the help!

[opal sinew]

Remove parent does not work here

Widget still appears

Any idea why?

[icy dragon]

Why not replace the branch with IsValid?

[opal sinew]

The branch works and the remove from parent is called

[opal sinew]

Though good idea

[icy dragon]

Nay, it's the best practice.

[dark crow]

Validate Get could work too?

And use the given ref directly

iirc it's more performant too

[winter kettle]

If I have a blueprint function that returns a value, but there are some paths in the function (like a branch) that doesn't return a value at all, and I call the function and it reaches the path that doesn't return anything, will the node that is executed/connected after the return-less function call be called?

[tame pecan]

Yes

[dark crow]

Yeah

[tame pecan]

And it’ll return the default parameters

[dark crow]

May be best practice to have a return for clarity anyways imo

[earnest tangle]

It's good design to make sure all your codepaths return a value so it's not unclear what is returned when

[worthy carbon]

https://youtube.com/watch?v=nc7F7IJLuik&feature=share (I tried this but i still can’t pickup my weapon) help me please

[tame pecan]

Yep

[tame pecan]

We won’t go through a whole tutorial to check where you did wrong. What goes wrong and show us the code where it goes wrong

[worthy carbon]

👍🏻

[snow halo]

hey peeps, are there any nodes to convert a color/linear color var to a hex string or somethin?

[worthy carbon]

i still cannot pick the gun up (Survival_Player = the character)

[earnest tangle]

@snow halo there should be a linearcolor -> hex node, if you drag from the color pin and search for hex you should find it

[snow halo]

Not seeing anything

[earnest tangle]

That's odd...

[icy dragon]

This.
I get quite annoyed when people ask other to watch through the tutorial and not directly showing the problematic code.

[earnest tangle]

Ohh sorry my bad, the function is from a color wheel plugin I have :P

[dark crow]

Are you testing on a server?

Cause that RPC is giving me depression

[worthy carbon]

no

[dark crow]

I bet it's not working cause Pickup has no valid ref

[worthy carbon]

okay, how should i fix it

[dark crow]

How are you setting Pickup

Let's do this to test first of all

Then press the Interact button

[worthy carbon]

oke i will test it

[worthy carbon]

i deleted the GET pickup node

so everytime i press E the weapon attach to the character

[dark crow]

As it should, no?

[tame pecan]

First of all, don’t multicast spawn actors

[dark crow]

For sure, lol

But for now he's not testing on server, so shouldn't matter

[tame pecan]

I just saw the multicast, reading on my phone

Currently on a walk 😅

[dark crow]

Core of the problem is that he's using a Pickup Ref, but not actually using it

Probs not even setting it right

So validate failed

[worthy carbon]

oh oke

[tame pecan]

Many issues with this code. I’ll join in when I’m home

[dark crow]

Yeppp

[late cave]

This is fascinating... it works outside of the function, but not inside of it...

[tame pecan]

Don’t rely on the blueprint debugger

It’s incredibly buggy

[dark crow]

Trash the blueprint debugger

[late cave]

You don't say 😭

[earnest tangle]

Yeah breakpoints and stepping is the only thing that works sorta reliably

[late cave]

but... I am using a breakpoint...

[earnest tangle]

Hovering over pins to see their values shows nothing useful more often than not :P

So it's entirely possible the value you see is wrong

[dark crow]

I would use a print if you really wanna see the value itself, only reliable way i found, but gets messy, lol

Then remove it after you're done if it's just a one time thing

[tame pecan]

Yes, but hovering over variables is buggy

[late cave]

Unreal Engine... debug like it's 1985! Woo!

[dark crow]

Unreal, right?

[late cave]

Truly the future of interactive entertainment...

[icy dragon]

As if Unity did something different in this regard...

[tame pecan]

Just wait until you find out that airports still use systems from the 80s

[late cave]

I used Unity up until 2017... you could watch all values LIVE in the details panels there... here, shit just freezes up

[tame pecan]

You can with unreal too

And it works

Just expose the variable

[late cave]

no... again, not while stepping through a blueprint

[tame pecan]

Yea no

[earnest tangle]

Sometimes it works... I wonder if they've improved it for UE5

Somehow I doubt it

[dark crow]

Probs broke it more

[earnest tangle]

btw it works 100% of the time in C++ :P

[tame pecan]

Usually works better with anything else than references

[dark crow]

Did someone say Rider??

[tame pecan]

Vs all the way

🤓

[dark crow]

Notepad all the way

[icy dragon]

I think I misbehaved in front of one of the Rider guys yesterday 😂

[tame pecan]

I use VS because its industry standard and I got a license

And I like it

[earnest tangle]

lol

[dark crow]

It's a love hate relationship

[tame pecan]

C++ in unreal is not that annoying. Epic has macro’ed the shit out of it

[icy dragon]

Imagine saying "Sorry but I use Visual Studio all the time because it's free" in front of one of the Rider team member.

[odd ember]

there are worse things than working with cpp

like trying to help people in a BP channel AYOOO

[icy dragon]

Yes: working with Unity.

[tame pecan]

GOT EM

[wraith bay]

I have a blueprint for a trap i put in my game, however I placed 3 of those. Is there a way to get each instance of that class that is placed in the world?

[gentle urchin]

working on someone elses structured text code, where they used 99% pointers

[wraith bay]

Like, it's Trap_BP, but then there's Trap_BP1, 2 and 3, is there a way to get each one?

[odd ember]

get them where?

[icy dragon]

Get All Actors of Class

Just don't do it every tick.

[dark crow]

Do it on a timer instead

0,0001

[muted halo]

Hey guys, is there a way to end my scene after a certain amount of time in my level blueprint?

[snow halo]

what's da plugin?

[wraith bay]

I have a button which disarms the traps, however if one of the traps was already activated/destroyed, i get an accessed none error

[icy dragon]

Define "end scene".

[odd ember]

use the level blueprint

do you have a OnPressed Event in the button?

[muted halo]

I mean like when I hit the play button I can make it so after 10 seconds the scene will stop playing

[earnest tangle]

@snow halo uhh I think it's called color wheel or something, there's a couple of them but it's the free one

[wraith bay]

Sorry no, not accessed none, its "pending kill"

[wraith bay]

Yes

[dark crow]

?

[odd ember]

that means someone already killed it

[odd ember]

show me your logic

[icy dragon]

Are you referring to Level Sequence?

[wraith bay]

Yeah, if I trigger the first trap, the trap gets destroyed. if I then press the button, whch is meant to kill all 3 traps, it gives me that error

[muted halo]

hmm I dont know the right term for it but I mean when I try playing/simulating my scene. Im trying to set something up in my level blueprint so that the scene will end after a certain amount of time. Not any sequences or anything

[icy dragon]

"scene" is a vague term, as far as general logic assembly goes.

[wraith bay]

Thats why I was wondering if there's a way to check and only destroy the traps that are still active

[dark crow]

Check if they're valid?

But it all sounds like a design issue in the end

[muted halo]

Yeah sorry haha. Like when i click the play button next to compile and launch. I just want the scene to automatically end after a certain period of time

[odd ember]

make a check first to see if each trap is valid

and only kill them if they are valid

[wraith bay]

Yeah but how do I access 3 instances of the same class

Get all actors of class?

[odd ember]

show me your logic

[wraith bay]

sec

[odd ember]

there are many ways of doing just taht

[dark crow]

Just depends why you would want one instance and how do you want to get it

[odd ember]

get all actors of class is the cheat code

I don't recommend using it unless it's a quick and dirty prototype

[dark crow]

Overlap is a pretty straight forward way to get one instance

[tame pecan]

Subsystem gang

[wraith bay]

I placed the 3 traps like this

They're all the same blueprint

Idk im new to unreal 😩

[dark crow]

Wait

Is this in the uuh, trap bp?

[wraith bay]

no

Button

Thats where im disabling the traps

[dark crow]

Oh yeah nvm

So what's the problem again? Pending kill?

[wraith bay]

Ye

because on the video

if i get hit

and then press the button

it also tries to kill the 1st one

but its not there anymore

because it got destroyed when i got hit

[dark crow]

Well

[wraith bay]

I guess

[odd ember]

this is very no bueno

[dark crow]

Part of the problem is that you kno

[wraith bay]

xd

[dark crow]

You have it in BeginPlay

Just GetAllActors when you press the button

After the DoOnce

[wraith bay]

Oh that fixed it

[dark crow]

Cause if you get at BeginPlay, still holds a ref of the already destroyed one

[wraith bay]

wow

Yeah makes sense

that makes A LOT of sense actually

holy shit

Thanks

I only have 2 weeks in unreal so Im trying

Thanks boys

[dark crow]

Neato

You seem to be doing pretty well for 2 weeks 😄

[wraith bay]

I would send you a little demo but its too big for discord

😦

[dark crow]

Everything is too big for discord when you need it

[wraith bay]

Oh wait I can send it

[icy dragon]

itch.io or GitHub releases.

[wraith bay]

This is still really raw so bare with

The main goal is to have a Shifting maze

meaning whenever you die

it changes to another layout

but i only have 1 layout right now

[odd ember]

well, kinda... as long as you dont press the button 4 times

[odd ember]

or there are more traps in the level

[wraith bay]

This video was before the new traps I did this morning

[wraith bay]

Ahh idk then :((

[dark crow]

Aye, looks good for that amount of time!

[odd ember]

that button will continue to destroy traps in level

until it runs out of traps

[wraith bay]

Ahh I see

[dark crow]

Do you place the button and traps or are they procedural?

[wraith bay]

I place them

Wait as in

I placed them manually

[dark crow]

Cause you could make an Array of Trap Actors, Expose it on the Button and assign the traps to the Button Manually

So you have a hard link between instances

[wraith bay]

I wanna have 5 layouts for this "biome", and I want to make the first one really hard, so it forces the player to die, and cycle through to the next layout upon death, if the player keeps dying, it'll keep cycling through the 5 layouts until they learn it and get through to the next biome, which will also have 5 layouts, and so on

[wraith bay]

ooo

[odd ember]

which is a step above get all actors

[dark crow]

If they are manually placed like he said, it should be no problem if random generation is treated like prefabs

[wraith bay]

Yeah idk how to do that xd

[dark crow]

So your traps have a BP no?

[wraith bay]

Yes

1 BP

[dark crow]

In your button create a new array variable of the trap type

Literally create a new variable and as the type use your trap bp name

[wraith bay]

Bruh I gotta start somewhere :((

[dark crow]

Level BP nightmare

:p

[odd ember]

nah, people give level BP too much flak

[spark steppe]

and others overrate it

[odd ember]

level BP is arguably the best OOP way of doing it

[dark crow]

Burn the heretic Level BP

Burn on the stake

[odd ember]

self registration is ECS god tier

[wraith bay]

You mean like this? @dark crow
