[lyric basin]

lol

lightbulb moment

[olive yarrow]

it's 8:30, i've been doing this for a solid 12 hours now

[lyric basin]

it happens

try looking for your custom function

[olive yarrow]

clearly making more errors than progress now :/

[lyric basin]

or at the very least change it so its named something different lol

[olive yarrow]

yeah seriously lmfao

i added an !

[lyric basin]

dont have editor open atm, so not sure if the engine includes a Start Dialogue fucntion

that should do it!

[olive yarrow]

😂L

[lyric basin]

so does it work now?

[olive yarrow]

no lmfao, but it's definitely on the plug in side. I just wanna get this done so i can relaaaaxxxx

[lyric basin]

okay whats the next issue

[gritty palm]

Sorry

I did not ubderstand

Mqybr I did not make myself clear enough.

Im noy trying to use UI for the game logic

Im doing it in bp actors

[olive yarrow]

I seem unable to start the dialogue via the line trace on my NPC, if i try via me i get Plugin specific errors

l;emme snag em

[lyric basin]

yeah I understood what you wanted. I was merely suggesting that the entire thing could prob be done using widgets that are just displayed on the screen for the player to interact with. Of course, all of the logic would be handled through BPs

[gritty palm]

Thanks

I tried opening that

But for some reason it didnt work.

I give it another try and see how it goes

[lyric basin]

yeah just upload a ss so I can see what its screaming about

[lyric basin]

better thx lol

[olive yarrow]

my participants are set...

[lyric basin]

lemme see the array logic

pls

[gritty palm]

Ok

Thanks

So what is your suggestion?
Im not a programmer. Im lookijg for some clues so I can figure out the logic

[lyric basin]

a minute ago you said that the UE4 project didn't open for you. what was the error you got?

[lyric basin]

ah man you're using a pallette lol I haven't used those before lmao. I though you were using a string of BPs to make the array. okay gimme a sec to look at this

[olive yarrow]

naaaah, Not Yets plug in

[lyric basin]

when you play the game, does any of it show as firing?

[olive yarrow]

lemme check, a lot worked earlier that doesn't now

[gritty palm]

It says I need visual studio and when I press "yes" to downloaf and install, it will freezes.

I am doing it now again

This timr im going to give it much more time 😅

My unreal engine freezes alot

Still dont know why

[lyric basin]

try downloading and installing VS outside of the engine. not sure why your system and engine are freezing. Could be software corruption or hardware issues but thats a whole nother problem unto itself

[olive yarrow]

What exactly are you looking for to be firing? as far as i can tell everything is - i can get a print string from the interact via both my playter and NPC interaction

[gritty palm]

Thanks

Im not sure where and how to install it

I triee years ago and I kmow there are different versions to VS.

[lyric basin]

oh okay thats progress lol. well, I guess just tryna figure out why it thinks the participants array is empty.

How are you loading them in there? Can you share a ss of the Start Dialogue logic and how you are using it?

[olive yarrow]

That's where i'm at... didn't have this issue before until i had tried to launch the dialogue on the NPC via a line...

[lyric basin]

community version should be good enough for what you are trying to do.

[lyric basin]

right, lemme see a ss of that part of the BP

as in, when its called

[olive yarrow]

ask an you shall receive!

there's literally allit

[lyric basin]

awesome sauce lemme look this over

[olive yarrow]

i'll be here muckin' with things

[broken wadi]

On your line trace you dont need to check Does Implement Interface you can just call it because any actor that was hit that doesn't implement the interface simply won't do anything anways.

[lyric basin]

alright, question. do you have two monitors? I got an idea

this is how i troubleshoot lol

[olive yarrow]

sure do what's the plan stan

[lyric basin]

alright so launch the game, do whatever you do normally and then exit. but dont close out the message log that contains the errors, just click the clear button at the bottom. The put that into the other screen. launch the game again and then pay attention to exactly when the error occurs while going through the same actions. You can then isolate this to the BP and identify the node causing the issue

make sense?

this works 99% of the time for me in helping me identifying the issue

actually fixing is another story, but you gotta know where to start looking lol

[olive yarrow]

maybe? the error occurs the moment i attempt to open the dialogue - be it via interact or just an overlap collision

[lyric basin]

at least its not on start lol okay so then its probably the second section you have commented out

event begin play doesnt have anything in it that should cause the issue.

[olive yarrow]

i create the dialogue widget, s'bout it

[lyric basin]

you could also open the editor in a separate window on game play and have the BPs on the side so you can see then firing.

this is the section I meant that I think is the problem

[olive yarrow]

i'm listnin'

hell i may just delete all the BPIs for dialogue and interaction, blue prints too then restart :/

ok

dialogue appears

idfk why or how i moved a few things

and i can trigger it via line trace

dude that's it i'm gonna go play some friggen halo

[gritty palm]

I managed to install the visual studio and open the project. it is mostly in C++ that I have no idead of it. everything else that is in the bluprint, it sems to be the logic for mathcing gems. There is nothing about the moving parts and other things.

with that being said, do you know any other tutorial that I can use to make the move logic for now, I can figure out the rest later

At least a genral idea on what approach I should take. I tried creating a BP for grid and a blueprint for gem as master and then made like 5 child of it. Then in grid Bp, I made an array for the gems and stoired all those gem child BP in it. and spawn them to fill the grid. I managed to use click event and as a debug test, now Im able to move the individual gems off the grid (to the depth of the screen) but I need to move them left and right/up and down and swap them with other gems. I think Im getting at this the wrong way. I think I should store the gems in the the grid points somehow.

[lyric basin]

hey sorry had to make myself some food but glad it worked! Sometimes values get cached or whatever and a line gets crossed. starting over just works lol

[lusty oak]

Anybody know why there is a Hit Hit Bone Name and a Hit Bone Name on On Component Hit? Is this just an error in UE?

[olive yarrow]

Homie you were helping me for free don't even apologise. I'm just glad to put to rest an issue that started at 11 and snowballed into one greater 😂

[lyric basin]

you could use a nested array for this it sounds like, to store the X and Y values.

[lyric basin]

no problem. glad I could help lol

[autumn torrent]

is there a way to maybe duplicate a mesh IN an actor when a condition is met?

very specific but I'd like to know

[olive yarrow]

You could have one mesh hidden until a condition is met 🤔

Someone will probably have a better idea tho

[dawn gazelle]

When that new condition happens (ie. whatever is happening to trigger that condition to be changed) have that flow of logic add a new mesh component and set its mesh to the one you want to have duplicated?

[lyric basin]

could you be a bit more specific? What type of actor and what type of mesh? Are we talking like a body growing another arm or something? Or a building growing in size?

[lyric basin]

first thing that comes to mind is 'Spawn Actor from Class' specify the actor and then for the location make a call to whatever it is that you wanna create a copy of, reference the location and plug it into the location pin of the Spawn Actor from Class node. This should, in theory, spawn whatever it is you wanna duplicate at a location of your choosing. Or if you wanna spawn it somewhere else in the world, like right next to you or the actor or wherever, just specify the location manually.

by that logic, since you are creating a new instance of the actor, it will run and behavior based on whatever logic you've coded into it.

but you said mesh, so what do you mean by that?

[quaint ravine]

Could someone here tell me what I did wrong? I want to make a projectile come out when I click but it happens to me that when I make the first click many bullets come out (I want one to come out) but when I press again they don't come out with that time from point A to point B. Could someone help me?

[karmic pebble]

Well for starters, you are running your event on a timeline

Which means that every tick in that timeline you are firing that event for however long you are running the timeline

Lets start with, what is your purpose for the timeline? What is your goal here?

[autumn torrent]

Literally duplicate a model within the actor

[quaint ravine]

So I researched (tutorials on YouTube) to make an object take X amount of seconds to go from point A to point B, so I figured it could be useful there.

[karmic pebble]

Okay so the problem here is you are using a spawn actor. The movement from one place to the next would be done in that actor itself not within whatever you're using to spawn it

instead what you have done is spawn dozens of actors at once

You want to spawn one actor and get its current point and its destination point, then you can lerp between the 2 locations with SetWorldLocation

for which you would use the forward vector to calculate

or.... you just use a Projectile Component and be done with it, setting the speed within it

Much easier

whatever location and transform that you spawn the actor it will take the forward direction of the actor

and since its a top down and you dont need an up/down axis aim thats even easier.

[quaint ravine]

Of course, but when you put it, the projectile is not propelled and falls under the map

[karmic pebble]

sounds like something is blocking and/or spawning it incorrectly

maybe something with physics, I couldnt tell ya without seeing it but thats the purpose of them

[quaint ravine]

And how do I make it so that when the projectile appears it is propelled forward?

or to the location where the click was made?

[karmic pebble]

well propel forward will be easy but as the click part that sounds like thats your issue

its sending your projectile through the floor because of your click. You are feeding your click data to the spawn transform in the incorrect way

I cant say i do much with click position on UI, so I cant give you pointers there, but more than likely thats your issue

[quaint ravine]

mmm okay thanks for the help

Good Luck!

Video that shows implimentation. Its kinda crude for some of it, but it seems to work

[quaint ravine]

oh thanks, I'll see if it helps me with my problem

[lyric basin]

I need specifics. in theory, yeah, but that's if you're typing it out in c++. Tell me what you are trying to do so I can try to picture the bps

[autumn torrent]

A burger building system, where you can put as many ingredients as you want and they’ll stack up as high as the player wants

[lyric basin]

so if the player wants to put 100 pickles on the burger, you want them to appear, yes?

[autumn torrent]

Yeah, they’d stack up

Even patties

The game Citizen Burger Disorder had a system like that, although it was made in Unity

[lyric basin]

Are you sure they were just making duplicates like you said? From a coding perspective, if you wanted to make a copy of something (say an object) you would be creating a new instance of it. In UE, you would be creating a new instance of the actor.

So spawning a new actor whenever the player clicked a button is totally doable

[autumn torrent]

Either copies or actors, I dont know how they did it, as the patties always stayed in place

[lyric basin]

though I would use hierarchical meshes as they should be more computationally effiecient.

yeah, just use the nodes I mentioned. as far as staying in place, thats just physics. you can disable that and they would stack to infinity lol

spawn actor from class is what it sounds like you need. as far as the location of the actors (like how the pickles stack and stuff and the different layers) thats location and collisions you wanna look at.

at least, to me thats all what makes sense in my head.

[autumn torrent]

It sounds like it makes sense, yah

Thanks :)

[lyric basin]

Yup np

[outer quail]

why is it showing index 0 repeatedly? I'm trying to use addunique in component_name_bp so that it would display index 0 and index 1

[lyric basin]

do me a favor. try connecting the array element output pin to the to text(string) node.

see if it works and what it outputs

wait nvm

[outer quail]

T_T which one, I'm a noob sorry

[lyric basin]

its ok

could you explain what this is supposed to do? like, what is going on in the game and what is the end goal?

[karmic pebble]

Have you confirmed what is in your ComponentNameArray when that function funs for GetText? such as setting a break point on the ForEachLoop and hovering over teh output of the ComponentNameArray.

[outer quail]

I'm creating a system where it calls info from firebase, then it will display it on the UI

I managed to call the name from firebase

[karmic pebble]

@outer quail can you go through what I mentioned here above and take a screenshot of the array. Or we can hop in a voice channel and you can screenshare.

[outer quail]

on component widget bp

[karmic pebble]

Oh perfect

okay so this is working here it seems, its just not carrying through. Since you are getting it to PrintString for you

[outer quail]

I use get actor of class to prints the propeller and engine, so it means that the engine and propeller is in the array right?

[karmic pebble]

well get actor of class is actually a node you wanna stay away from.

they arent exactly reliable to always return the one you want.

it just returns the first one it finds

so if you have multiples it could return the wrong one, if you only have one ever loaded, then its somewhat reliable.

[outer quail]

I see, so if I don't use actor of class, is there any other way to pass the component name array from component name bp to other blueprint?

[karmic pebble]

How do you create the component? Is it part of controller or something?

Because you can pass a direct reference to it upon spawning or set it after spawning it.

[outer quail]

I call the component's name using a firebase plugin

[karmic pebble]

but more specifically i was wondering what this variable says when you breakpoint this.

okay so you just have this component on a BP and placing that blueprint in the world?

[outer quail]

yup

[karmic pebble]

only one of them yes?

so technically this SHOULD be okay, but if unreals garbage cleaning starts acting up, you could technically return an old object.

[outer quail]

only component_name_bp. in the mainscene, I use add to viewport

[karmic pebble]

and there is your widget. Okay. Yeah i mean that should work but there is some safer ways of passing your reference, but thats not the issue atm. Try the breakpoint from above and hit play.

Lets see what that array says when you hover over it. That will tell me if the data is making it that far or not

[outer quail]

what do you mean by breakpoint?

[outer quail]

this?

[karmic pebble]

Yes, so go ahead on the top part of that node and right click on it

Add Breakpoint

Then when you hit play

the whole editor will freeze

and take you to that node

at that point and time, you can hover over any executed variables in the previous path and see the data there. well... usually

[outer quail]

yea its freezing xD

[karmic pebble]

mhmm!

thats good

[karmic pebble]

now whats that array pin saying below

not there the 2nd arrow, hover that

This shoudl contain both Engine and Propeller if the data is passing correctly from your component

[outer quail]

so I click play and the editor freezes, then hover on the array right?

[karmic pebble]

correct when you hover over that output pin it shoudl show you

OH!

dont forget

at the top make sure that NO Debug object Selected

is dropped down to your Widget

outside of play nothing should be there

during play that should have one item in the list

[outer quail]

its not showing anything 😦

[lyric basin]

should be able to use the round node, which you have highlighted

[trim matrix]

But i want to round up, not round

like 5.1 to 6

[lyric basin]

try using ceil to integer64

[trim matrix]

oh, its called ceil, thanks

[lyric basin]

or just ceil

yeah np

[karmic pebble]

Well i dont see you hovering your mouse over the pin. 🤔 Lemme take a short video to show you, just to make sure since you arent yet too familiar with debugging. One sec please~

[outer quail]

I just noticed something new, I tried printing the get text that I'm using for my text block, it only print index 0

[karmic pebble]

well you are running this function on tick technically

[lyric basin]

btw for what its worth, the opposite is called floor lol. imagine that

[karmic pebble]

that might be part of this issue. but its going to be hard to troubleshoot this over pics. If you wanna hop on voice in a channel we can.

otherwise assistance at this point might be difficult.

Too many variables and minor things here in the setup.

[outer quail]

I'm at my office right now and I don't have mic 😦

or do you think that the loop is not working properly?

[karmic pebble]

well heres the thing. from what I am noticing you are trying to make a selection system to choose a product type then display all the subtype stuff right?

and it needs to be dynamic populated based on parent categories?

[outer quail]

yup

[karmic pebble]

click on engine and see all the brands

or click on propeller and see all the brands

etc

[outer quail]

yea if click on the engine you can see info etc

or I should not use text block?

[karmic pebble]

okay so then you are going about this a bit wrong then.

You need subwidgets

[outer quail]

I want it to list out here engine, propeller, etc

[karmic pebble]

you need to dynmically create subwidgets from your array information

correct

[outer quail]

owh

[karmic pebble]

this is like an inventory system for a game

[outer quail]

yess

[karmic pebble]

Mhmm. I could show you the dynamics of it in about an 30 minutes

but its gonna be hard to explain via text.

i would lookup inventory system basics tutorials

and it might help make the links for you

[outer quail]

its okay, i will try find a video about it

[karmic pebble]

🤔

yeah! exactly

[outer quail]

if you found a good one for beginner that would help me a lot thank you

[karmic pebble]

https://forums.unrealengine.com/t/tutorial-simple-inventory-system/1316560

This uses a uniform grid but you can swap for the Horizontal Box just the same

thanks I will take a look at it

[karmic pebble]

https://www.youtube.com/playlist?list=PL4G2bSPE_8umjCYXbq0v5IoV-Wi_WAxC3

and here is an indepth system.

Might recommend making a second project and following it, help you kinda make the connections and re-apply those to what your doing

but yeah essentially subwidgets are what your looking for

[outer quail]

got it thank you! appreciate your help a lot

[karmic pebble]

No worries! Good luck!

[strange carbon]

@outer quail i agree with Darinius about making a second project when following tutorial. Cause I made that mistake on one of my projects trying to mix it with what i had and had to go back to square one for my inventory. (Also Ryan L visited one of my zoom class's and is a very chill person lol)

[frosty heron]

Use source control

[gusty portal]

does apply damage node not pass the float accurately?

i have 2 attacks 1 light and 1 heavy
i put the dmg of light to 10 and heavy to 30 but both of them are doing same dmg

ok never mind it was just an issue with a threshold

i'm using the notify color to check which attack i'm doing and idk if that's the best approach. i'd like to know if there's a better way to know which notify is firing the recieved notify tick

[cold lion]

Hey im trying to add a delay here before the next line trace, I tried adding one but got an error as well as it not working, the following line traces are configured at certain rotation to give a "spread feel" I just need the delay to work?

[frosty heron]

You can't add delay in a function

[cold lion]

so how could I handle this? this is my rifle set up

[silent drift]

Is there a way to do "TODO" comments in Blueprint that I Can find later? I'm thinking of in VS Code, I can add a "TODO" and that is marked as a keyword I can later find easy in a list of TODO comments. Rather than me having to remember that I want to go back to something (Since I want to test it for a build and then fix it if players like it).

So I don't leave the bad BP stuff in there. 😄

I guess BP comment KEYWORDS is kind of what I'm looking for.

[frosty heron]

What is it you want to do, I can't read from my phone

[cold lion]

the end goal is to have something when alt firing to make the line trace or traces fire in a horizontal line in order to simulate firing a gun side to side, covering a small area of effect

[sour warren]

Hello, I'm creating a VR installation and I changed the teleport to continuous walking and it works fine, and snap turning to smooth turning but sometimes when I turn left it gets stuttery and/or slower than right turning. In the turn input action the value type is set to Axis1D(float) being right +1 and left -1. What can I do to resolve this problem?

[frosty heron]

Not sure what you mean sorry. But in the case of firing automatic gun, don't use delay but timer instead. I never see any different solution when it comes to automatic gun. Everyone opt to use timer

Delay shouldn't be an option as you are not able to control the execution once a delay node is run

[cold lion]

Here is a video with a timestamp of the effect I am trying to get, if that helps, so a timer would work then? https://youtu.be/YfSKttKEgIs?t=140

[frosty heron]

I will deffinitly use timer for the continues gun fire

At basic level they are controlled with mouse press and release

[cold lion]

Ive got that down but im wondering how to either move the line trace horizontally, so setting a timer to trigger another line trace in another location relative to the horizontal spread might work?

[outer quail]

I managed to pass the array to scroll box, the array contains 2 index but in the scroll it only shows index 0 non stop multiple time. I want it to only show 2 name (Engine and Propeller)

[cold lion]

did not mean to react so sorry

[outer quail]

[frosty heron]

You are only getting the index 0

Also the casting is pointless because it's already the type

Refer to your first picture. That's where the problem is

[outer quail]

but the array is from other bp

[frosty heron]

Don't matter

U can just drag from the return value and get the array right away because it's already the type

No need for casting

It even tells you that in the log

Get rid of the get and cast for a start

[minor pollen]

Hey
I never had issues with that but now i do.
When i change some Class Defaults settings in my Blueprint, compile, save it and then reopen my Project all changes that i made to the Class Defaults are gone and everything is set back to the default settings.
Does someone have a solution for that?

[outer quail]

can't find component name array

I'm new to this sorry

[frosty heron]

Don't delete the get all actor

Just the cast and the get 0

Put the get all actor back, pick the right actor. The connect the return value to the component name array target

[outer quail]

ahhh

[frosty heron]

Ok now get rid of get 0

U don't need parse into array as well

Then show me the whole pic after u done that

[frosty heron]

P.s avoid get all actor of class in the future, there are better ways to reference objecrs

[outer quail]

any keywords I can use to search about it?

[frosty heron]

Blueprint communication video by Matthew is good example but let's focus on fixing the problem

Why r u printing engine many times?

What's the expected value here?

[outer quail]

idk its not supposed to do that

only to display index 0 and 1

or just any index available in the array

but it keeps on repeating

[frosty heron]

What is this get text function? Where did it get called?

[outer quail]

widget

[frosty heron]

Delete it, that's not the way

[outer quail]

dang alright

[frosty heron]

Add a vertical box under your scroll widget

Btw I know why u printing soo many engine, u bind it to the text

It just keep adding text every frame and only return the first one it found

[outer quail]

event graph

I tried to do it like this but its not working

[frosty heron]

You are suppose to add the text at run time

Not manually dropping it into the widget

I believe you wanted to get some data from your firebase api right?

[outer quail]

yup

so remove textblock?

[frosty heron]

Ok so you make them at run time, according to the data given

Yea delete the text block

[frosty heron]

Let's do some debugging here

, print string the array element from the loop body

[outer quail]

am I doing it wrong?

[frosty heron]

Print string the return value

We need to find out if the actor exist at all in the level

[outer quail]

does that mean I have to put print string at the end?

[frosty heron]

No, do it right after get actor of class

[outer quail]

like this?

[frosty heron]

drag the return value to the in string. We want to print the objects name

[outer quail]

ahh I see what you mean

didn't know you can do it like this to check

[frosty heron]

Ok now in the world you are in

Did u spawn component name bp

[outer quail]

yup

[frosty heron]

Or did u drag and drop one in the level?

[outer quail]

drag and drop on the level

[frosty heron]

It's grey, so it's dropped to the level

K click on that component name bp

Then look at its properties (component name array)

Screen shoot that

I am betting it's empty

[frosty heron]

Hmm

[outer quail]

I guess there is no problem with the array right?

[frosty heron]

Well we tried to print string earlier but nothing comes out

Let's look at it again

[outer quail]

yup weird

[frosty heron]

Show the code as much as you can

Oh wait we actually haven't print string

[outer quail]

widget bp

[frosty heron]

On for each loop, print string the array element

Then screen shoot the result

[outer quail]

this?

[frosty heron]

Yeah that

R u still getting nothing? Make sure to add a lengthy time to the print string duration

[outer quail]

yup

weird

[frosty heron]

Let's print the index instead

Connect the index to the print string

[outer quail]

T_T how do I do that

I usually just print string on the component name bp and it works

[frosty heron]

From the loop body, you see array index. U can connect the green pin to the print string

[outer quail]

owhhh

[frosty heron]

K where u are detached from the controller

Next to the stop button I think u will see an up arrow icon

Press that to eject from the character

Then go to the outliner and look for your bp component name

[outer quail]

okay this one

[frosty heron]

Then same deal, look into the array values

Yes that one

[outer quail]

detached

mb

[frosty heron]

🤔

I am puzzled why it print nothing

[outer quail]

do we have to use get array or something?

[frosty heron]

Not really, for loop with go thru every single element

Are there multiple component name bp in the world?

[outer quail]

nope only that one

[frosty heron]

K do this, on component name array. Drag from it and type length

Then you want to print that value. Do it before the loop body

[frosty heron]

For sanity check, can u add delay on construct

Before get actor of class

Just add 4 seconds delay

[outer quail]

hahaha alright

yooo it work

wth how

[frosty heron]

I think you modify the properties somehow

We can't be doing rat race as well. So I think at the start the value is empty

But then u fill it after u make request with your api

Which takes time for the data to be retreived

If we construct the text before that data arrive then we get nothing

[outer quail]

owh I see

[frosty heron]

Show me how you retrieve the data from firebase

[outer quail]

but if I use ontick it appears immediately but the problem is it repeat itself

I use plugin

[frosty heron]

On tick happend every frame, u don't want to use that either for this context

[frosty heron]

Now that u showed this. It all make sense......

K back to the widget, right click empty space. Create custom event.

Call it initialise data

[frosty heron]

Ok now connect that to the get actor of class

U don't need the delay or construct

[frosty heron]

How fast is your widget created btw?

[outer quail]

instantly

[pliant zenith]

hello, I have a question about how to set the maximum camera movement (so that you can't do a 360 with the camera on the spot without moving the character).

[outer quail]

on screen

[frosty heron]

Go here and create event dispatcher

[outer quail]

custom event?

[frosty heron]

You can use clamp to hard limit a value. You will have to figure out the code tho

[frosty heron]

No event dispatcher. Go to the variable tab, there will be event dispatcher section. Press the plus button

[frosty heron]

Not a function

[outer quail]

found it

[frosty heron]

Rename it to data_retreived

[outer quail]

do you want me to call it or?

[frosty heron]

On the retrieve function after the loop

So right after the completed pin

[frosty heron]

Drag drop, call

[frosty heron]

Do it on empty space

Connect from completed pin, not the loop body

U will be broadcasting the event prematurely

[outer quail]

got it

[frosty heron]

Now back to the widget

On construct get actor of class. Component name

From the return value type assign data_retreieved

[pliant zenith]

I've got something like this and I still have sort of inverted control when I move the mouse to the left the camera goes to the right and when I move the mouse to the right it goes to the left

[frosty heron]

Not like this

Disconnect after the bind

From data retrieved event you can get actor of class again then connect to the loop

[outer quail]

this?

[frosty heron]

If u got inverted control, maybe try to multiply the value by -1?

[frosty heron]

No

Event construct get actor of class. Bind data retrieved

Don't do anything else there

[outer quail]

just like this?

[frosty heron]

No u are still connecting the loop in construct

After get actor of class connect it to the bind data retrieved

[frosty heron]

K better. Now move the data retrieved event down and the for loop as well

[pliant zenith]

okay fixed thx

[frosty heron]

From data retrieved event, make a new get actor of class. Component bp name. Then connect it to the loop

[frosty heron]

Test it

Don't need the print strings anymore

[outer quail]

wait my ue5 crashed T_T

[frosty heron]

This is wrong , I didn't watch

U need to do the same as above

Get actor of class not get all actor of class

[proven garnet]

Hey there must be a super simple way of having a static camera as the player right? Imagine a game of jenga or something, the player just needs to be a static camera in a scene and the gamepkay is to click on objects in the scene. Can't I just make this change in the project settings somewhere?

[frosty heron]

Just make a bp with a camera and assign it as the player

[proven garnet]

That's what I'm not finding, where to set the camera as the player

I've chgecked in project settings but maybe I'm blind

[frosty heron]

Player controls a blueprint class, it can be what ever. In your case it can be a basic actor class which have a camera

[frosty heron]

Create new bp, actor class.
Name it for example my player

Then just add a camera component from the component tab

[outer quail]

😦

[frosty heron]

Instead initialise data , use on construct

[proven garnet]

Yes I've done that but where do i set that BP as the player camera?

[frosty heron]

You mean how to set the default player as that player?

You can look at the world setting panel

Unreal basic frame work, you have player camera manager, player character , player controller, player state, game mode, etc

U don't need to play with camera manager for simple game imo. Simply make a new actor that has camera and assign that as your player via game mode

[proven garnet]

Camera is a BP. How do I make that camera my players view while playing the game?

[outer quail]

every time I run this it crashed my UE5 T_T

[frosty heron]

Well I suggest to create a bp which have a camera and assign that as your player via game mode

Don't know what else to say

[frosty heron]

Let's see where you call data retrieved

[frosty heron]

Show the widget again now

[proven garnet]

I have created a BP, that's the camera in the pic. This is what I see in the game mode. Where in here do I change to that camera?

[frosty heron]

U gotta stop thingking about camera. U are assigning the player which have a camera

Possessing the player will auto activate its camera

See where it says bp first person character? Change that to your newly created bp that has the camera

[frosty heron]

The top get actor of class shouldn't access component name array

Remove that

Then move the entire loop to align with data retrieved event

[proven garnet]

Tried that, there's no BP_Camera that I can select there. I can't selkect the BP_Camera in any of the menus in the game mode

[frosty heron]

Mb it has to derived from a pawn class

You can reparent it or just make a new one

[outer quail]

select none or remove get actor of class?

[frosty heron]

Don't remove it

We just don't want the component name array on the top section

[outer quail]

owh

[frosty heron]

The construct just needs to bind to the event

[frosty heron]

Ok but wait

Save the work

[outer quail]

it crashed xD

[frosty heron]

Ok do the same again but let's just print string from the data retrieved event. Print hello is fine

Don't go through the loop

[frosty heron]

Dont

From data retrieved event just print string

We don't want to commit to the loop

Trying to check how many request is actually made and if it's the cause of the crash

[frosty heron]

From print string disconnect

The right hand side pin

We do not want to commit to the loop

[outer quail]

owhh

only this

[frosty heron]

Yes

Save and test

[frosty heron]

K

[proven garnet]

Had to be a pawn but also had to check player 0 as auto posses

[frosty heron]

If u want to drop it into the level then yes

There is also a way to posses a static camera

Get player controller -> set blend view target

For games like what u describe, that might come in handy

[frosty heron]

Show the whole picture again

[frosty heron]

Add a delay then connect to the loop

[frosty heron]

Try delay until next tick instead of that

[outer quail]

alright

idk how but without the delay it crashed my UE5

[frosty heron]

I almost have no delay in my project

It's a bandaid most of the time and not a true fix

But in your case it's fine imo

[frosty heron]

All good now?

Clean up maybe. Get rid of the print string and the delay with the number

[outer quail]

alright all goooood

thank you so much

[frosty heron]

No worries, gl next

[outer quail]

there's so much to learn

[steel shadow]

Hey I'm wondering if someone knows how to do that : Basically I want a box trace to tick once I trigger an animation for the duration of the animation. So is it possible to have an event tick that activates only for a couple seconds and how would you do that ? Thanks !

[lyric basin]

The box trace by channel node accepts and exe input so you could trigger it by almost any input. So you could probably just put the box trace node after your animation node.

[cedar sky]

Why Both Possessed and Unpossessed Events are firing when Possessing Pawn?

Possessed Event also seems to fire when Pawn is Spawned

[thin panther]

Possessing a pawn first unpossesses it

[cedar sky]

whoops

forgot to disable autopossess

[neon lion]

i renamed the blueprint of my character (I think that's what caused it) and now the controller isn't spawning the character when i hit play
how can i debug this, where can i check and reinsert the character

[atomic salmon]

@neon lioncheck the GameMode. Strange because it should have been auto-renamed.

[neon lion]

what am i looking for here?
I have been editing the controller's code, but the character, not the controller, is what i renamed

[zealous moth]

fix redirectors?

[atomic salmon]

DefaultPawnClass but it also depends where you spawn your character from

[neon lion]

how?

[zealous moth]

select all your folders, right click, fix redirectors

could be a cache issue

[neon lion]

hmm, putting the hero in there fixed it, odd. thank you!

[lusty elm]

Is there something i could use here rather than getting the player by index? This is the function that gets called when an enemy is clicked on

Set Interact Target is a function that in the Player BP, it moves the character in range of the enemy then interacts with it

But i heard getting player characters by index is not ideal. Since i'm using onClicked i'm not sure how can I link that click to the player character

[untold fossil]

What is the best way to push a character back (ai enemy) when they get hit? I have a punching mechanic and I want the enemies to be pushed back (smoothly but rapidly) when they are hit. I've tried many many things like adding impulse, launching, setting velocity, nothing gives me the desired effect. The closest I've gotten is an impulse that pushes them back, but this happens instantly, like they are teleported back which is very ugly and not what I want. I need help 😦

Ai enemies are characters that use the character movement component (which is most likely the real culprit, that thing is a b*tch to work with, excuse my french :P)

[dim agate]

"The closest I've gotten is an impulse that pushes them back, but this happens instantly, like they are teleported back which is very ugly and not what I want."

Can you add a lerp between the beginning and end locations?

@untold fossil

[dark drum]

Does anyone know of any resources for making AI and Player controlled characters function the same? I'm currently looking at making an interaction system where it functions the same for both the player and AI but struggling to connect all the dots lol. It would be nice if there's any examples or reading material that go over any do's and don'ts.

[dark drum]

When you say it's not what you want, what are you wanting? Impulse is normally enough but if you're wanting something more fancy, sometimes you might need to use montages with root motion where they step back.

[gusty portal]

guys how to load save data? i am opening the level in game instance bp and i need context of if it's through a load game or if it's a new game

[dark drum]

Unless you're making a local multiplayer game, using get player character is fine. The alternative would to not use the 'ActorOnClicked' event and create an actor component you can place on your player character that handles clicking on stuff.

[gusty portal]

is there something that i can do with the options string?

on open level node?

[dark drum]

If you're handling it via the game instance, you can bind to the on level loaded to trigger stuff to load their data from the relevant save game objects and initialize the data.

[gusty portal]

so i shouldn't/can't use open level by name node?

[dark drum]

You could but if you change the name of the level, you'll have to update the string you enter. 😉

[gusty portal]

well i can't because open level doesn't give me a level reference

and load level loads the level into a sub levels list or something apparently from the tool tips

also i need to change the reference either way in this too right?

[dark drum]

Ahh my bad lol. Alternatively, you can create an actor component that handles saving/loading. Actors that need to save an load register with this actor. When it's loaded in the level, you can have everything else do it's thing.

[verbal wren]

I am a bit stuck trying to swap between player pawns, I have tried a couple different set ups but always get a version of "can not find or access" my Emily_BP. These are the two relevent blueprint functions as I swap into the new pawn

[untold fossil]

I just want a fluent / smooth pushback rather than an instant telelport-like push back really, not much else. Doesn't have to be super fancy.

[untold fossil]

The problem is that you can't force the location when an actor is using the character movement component. It's quite aggressive and takes over everything. Even disabling it still causes it to somehow block a lot of movement related stuff you're trying to do.

[gusty portal]

the issue i have is i need to be able to differentiate between if i opened the level from one event or other of the game instance bp

within the opened level bp*

i guess i can use a bool?

[dark drum]

Try adding some Z on the impulse, I've found not doing so results in the actor dragging on the floor which means you have to use move force to have it move. Alternatively, you can manually set the actors location using a curve.

[dark drum]

How come?

[gloomy pike]

Quick question as newbie , my level default player controller wont load if i switch from different level. But it loads if i open it directly

what is causing this ?

Couldnt find anything online

[fluid lance]

is it possible to edit a blueprint class via editor utility bp? Im trying to make a tool to replace all static mesh components inside a selected actor for an extension of static mesh component

[thin panther]

you should be able to pass whatever you want into the options string and parse it on the other end

[gusty portal]

well the main menu level has the main menu widget
where i have 2 buttons(i'll simplify it to 2 buttons although it's slightly more complicated)
1 button is to start a new game
2nd button is to load a save game
both will fire off an event(i didn't yet code the new game code but this is how i'm thinking it will work)
in the game instance bp to open the level in two different events
so i guess i can just have a bool in game instance class called isNewGame and in beginPlay of the level blueprint i can just check that bool and load the save

[supple dome]

You probably should use redirectors for that

[dark drum]

Each level uses its own gamemode so check the level you're loading uses the correct one.

[supple dome]

if you just want to replace one class for another

[gusty portal]

idk how to "parse it" idk where or how i would pull those options string

[gloomy pike]

Each level has its own game modes and those game modes has their own controllers. So if i load the levels manually their corresponding blueprints loads. But if i switch levels it wont. I did print texts to see if it loads or not. I does not.

[supple dome]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/ProgrammingWithCPP/Assets/CoreRedirects/

[thin panther]

You can parse that string via a game mode

[fluid lance]

hmm but that would replace all sm components in the project, right?

[supple dome]

depends on what you specify, you can probably filter for a certain class/package

[gloomy pike]

So if i switch level from Boot to main menu. My widgets wont be added because player class wont load.

if i open the level manually it works.

Pc_Mainmenu

[winter pebble]

What's the difference between the left and right versions of 'IsCrouching', and when can/should you use one vs the other?

[gusty portal]

so when i'm opening the level, the character is not being possessed again

[gloomy pike]

So basicly when i switch levels my game mode wont load, any idea why ?

it does load when i open the level by hand

[gusty portal]

nvm my issue was that i needed to also change the input mode back to game only but now the mouse isn't gettting hidden although i did also set show mouse cursor to false

[cedar sky]

Why the propeller is getting stuck?

Pitch doesnt go past 90

seems i have found out the reason. only Roll can spin like a propeller. other values only accept 90 to -90 values

[severe siren]

Is there a way to check if the foreach loop "broke"? Or will I have to add another event before I break the loop?

[gusty portal]

why do you need to check it?

just do the logic you want to do right before you break the loop since you already have a check when you need to break it

[severe siren]

Trying to make my blueprints clean and readable, just asking if there is a way

[gusty portal]

calling a function/event is the only way

afaik

apart from what i said which you'll still need to do call the event/function right before you break the loop

you can also collapse the logic into a node

or a macro

[celest trench]

Hey everyone! Is there a simple way to "shuffle" keys in a map like you can with an array? Or anything similar. I'm just trying to get the keys in a random order in the simplest method possible while still having access to the values.
I know I could do something like get keys, shuffle, search map for that key to get value, but is there a method that requires less nodes?

[severe siren]

Good idea 👍

Thank you

[dark drum]

Entries in a map are unordered and generally appear in the order they were added. Getting the keys and shuffling the array is the only way to get a shuffled key list but this wouldn't affect the map itself.

[celest trench]

So if I do this I would have to set a new array and then shuffle? How would this function in regards to the map? Do the key value pairs stay and the map does get shuffled, or does it only shuffle the array of keys which are stored nowhere since they are directly from the map?

[thin topaz]

How to add an output pin to a multiply operator node?
For example here to x, y, z:

[gusty portal]

map doesn't get affected

only the array is shuffled

[celest trench]

You change it to output as a vector3 and then you can split it into each float

[celest trench]

Thanks 🙂

[gusty portal]

just pull the pin to the other nodes

you can't have multiple pins but the single pin can give multiple lines

[gusty portal]

oh he meant like breaking the vector

[celest trench]

That's what I thought he meant at least, not sure

[gusty portal]

yeah unhook the pin right click on the pin and change it to vector then break it again by right clicking it again

[thin topaz]

thanks! it was not intuitive as it only gave me 2d and 4d vectors when i right clicked.
But somehow by accident got it as I wanted:

[gusty portal]

It's a bit finicky. Usually i just make the node again without changing its type fron vector multiply to vector output then only converting the input after hooking up everything else to not mess with it.

[dim agate]

What causes the camera to move up along the z axis like this? It doesn't seem to matter what I parent it to.

[gusty portal]

Maybe something in code is changing its transform?

Or maybe you locked it's z position?

Somehow?

[dim agate]

Location is relative to the parent, which at the moment is the mesh.

[gusty portal]

Don't parent it to mesh

Usually not a good idea

[dim agate]

So it shouldn't move relative to the mesh as far as I'm aware.

[gusty portal]

With all the animations and stuff

The the mesh the root?

Change it back to capsule because as i said the transforms might get weird with animations.

[fiery tiger]

I've got a noob question that I'm having trouble getting a straight forward answer from google. I want to set an int variable & feed that into a random stream variable. I'm utilizing both of these variables in other blueprints for PCG & a weighted array. Both of these are needed at runtime and I'm noticing that the seeds aren't always producing the same result each time. My hunch is that it's because I'm not setting the variables in the right place/time so I'm having some things load/populate with a different seed before the value is set.

My question is... where is the best place to set variables that are needed before a level loads?

[dim agate]

I've tried parenting it to the collision capsule, same effect.

[gusty portal]

I can't help much without more information

[dim agate]

Not much more to give. All the transform values are relative to the parent. Changing the parent from the mesh to the collision capsule results in the same issue.

[gusty portal]

Try deleting the camera and adding a new instance

Camera component*

[dim agate]

I have, same issue.

[gusty portal]

If it's not a setting you messed up in camera component, and you are not changing anything in code, and the parent is also not affecting it... Then what else can it be?

[dim agate]

Seems to be just what the camera does normally; this in a fresh template.

I mean, I'm hoping it's just the mesh and the way it's animated when standing/walking on the slope changing its height relative to the ground and camera while the actual height of the camera relative to the floor is actually remaining consistent.

[gusty portal]

Could be the ik

But it shouldn't be that much different. It should still be in the same range.

[gritty wraith]

Asking the experts here, what would be the best format to save a machine which is a 5x5 grid of different classes inheriting from a class Unit as well as inputs which can be rotated? (units have non-relevant rotation)

[lofty rapids]

a way i like to save data is in an array of strings, where you parse the string with a delimiter like , : | etc...

kind of like an array in an array
so you could have something like ClassName,Rotation,Somethingelse

[neat wagon]

does anyone know how I would dynamically get the checkbox that was checked, as an axis? Terrible phrasing so let me explain.

1. You have a location.
2. You want to set the location of an item based on the checkbox that was ticked, using them as axis.
3. You have 3 checkboxes, X, Y, Z. Any combination of these can be set to checked.
4. So if I have X checked, then I want to set the location to be added to the current location + X. If I have Y and Z I want to use both of those axis.

I know I can literally do all this in long form (create a branch for every different combination, but that ends up with 6 different combinations. In programs like maya I can use python in a way like the below (sudo code):

checkbox_x = (False, 'x')
checkbox_y = (False, 'y')
checkbox_z = (False, 'z')

my_checkboxes = [
    checkbox_x,
    checkbox_y,
    checkbox_z
]

for i, checked, axis in enumerate(my_checkboxes):
    if checked:
        set_actor_location(f'{axis}.the-value-of-that-axis')

If you're responding, please reply or @ me so I see it ^_^
I'm open to simply using theory, or if you have examples, I would gladly take that.

[gritty wraith]

json is a possibility too

[lofty rapids]

also a good way to store data

[gritty wraith]

i just dont know how good

i mean i do have a file manager plugin for bp

[lofty rapids]

maybe there is a plugin for that ? i don't know if it's out of the box

[gritty wraith]

actually, no, i'd have to parse it or something, i'd have to make multiple new classes, json is not good for UE bp

[lofty rapids]

i like splitting them up like arrays, kind of gives a 2d array

[gritty wraith]

the worst part is how specific this is... like, i have multiple classes that don't need rotation and than theres one that does...

[lofty rapids]

usually for something like that i just put empty setting

className,,,,,,

[gritty wraith]

i mean i would ask chat gpt but we all have our fair share of experiences about asking it... anything...

[lofty rapids]

you could create a complicated data structure

and save the game, load the game to get the data

[gritty wraith]

at the same time i could just save the objects... an object list...

[lofty rapids]

you want to store it in a file also ?

[dark drum]

Would any be able to explain whats happening with this? So you would assume that as shown in the image, you would get the original AI controller as at the start of the chain. However, this returns the original player controller that first possesed the pawn despite having them unpossess and the AI controller posses the pawn. I'm a little confused.

[arctic cloud]

Hey everybody, anyone got an idea of how I can get a Controller Disconnection Event, or a event being called when a controller is disconnected, through blueprints?

[dark drum]

Something like this maybe. (not sure if it would actually work)

[spark hound]

help somebody pls

how to use the source git hub thing

how can i undo the last thing i did in the project

i cannot open it if i dont undo it

pls help

i put the material as the landscape material and it crashed

[lunar sleet]

You can usually discard that specific change

[spark hound]

how

[reef bloom]

5.3.2
Trying to disable collision between players and the props on the map (StaticMeshActor) by pressing a button (Z), I can see them in the print string but I still have collision with them

[lunar sleet]

Not sure about GitHub desktop, VSCode has a button next to the file name. Maybe check with #source-control or Google

[lunar sleet]

1. You should check if anything else on your character (like a capsule) is set to block them.
2. You might need to do it both ways (another ignore while moving with reversed inputs)
3. That node says “while moving” so if those actors aren’t moving that won’t work. It’s usually used for projectiles. An alternative is set collision response to channel node and ignore the channel your character is in, (pawn might work or make your own custom one )

[reef bloom]

It was the first one, when I changed it to capsule it worked. Thanks for the help

[glossy aurora]

Is there a way to get all buttons in a user widget to iterate over?

[dawn gazelle]

"AIController" is a custom variable, so whatever you happen to store in it is whatever you've stored in it. It's also a bit redundant to get a controller, to get its pawn, to then get its controller again.

If you were to print the "AI Controller" display name it should be the same as the response at the end of your chain.

[dawn gazelle]

If they're all within the same containing widget, you could get its children.

[dark drum]

The AIController var is of type 'AIController' and yes the example is redundant and was done to track down a bug. It appears that despite having a player controller unpossess a pawn and have an AI controller take over. The pawn still thinks it's controller is the player controller for some bizzard reason.

[glossy aurora]

Which function?

THis one?

[dawn gazelle]

Depends on the type of widget they are contained in.

Something like this

[rocky rain]

anyone know how i can get my kart controller to rotate along the normal of a surface, this is so the player can always land on the wheels smoothly, right now i just have it rotate to 0,0,0

[dark drum]

I'm still trying to figure this weirdness out. So I possess a newly spawned pawn (doesn't do anything) and possess it with the player. When this happens, i then spawn an AI controller that then possesses the recently, unpossessed player character however, when I get the controller on both the Character and Ghost pawn, they both have the player controller. o.O

Does anyone have any ideas?

This is the possess/unposses logic on the character in case it helps.

[dawn gazelle]

What does your "AI Controller" display name print as?

[pliant zenith]

who should get which controller

[dark drum]

The character should be controlled by the AI but the player controller keeps track of who it passed control too.

[trim comet]

Hey, I'm wondering if there's an easy way to choose an execution path/outcome based on a matrix of conditions. For example, if I have 4 conditions I'm checking against, it would be great if there was a way to do this through some kind of matrix analysis rather than doing a bunch of Branch node chains for each possible combination.

[mortal nacelle]

how do I change the background music?

play sound 2d does not return any object that i can call stop / fade out on

[pliant zenith]

so the player controller should be displayed next to the ghost and the AI character next to it?

[dawn gazelle]

Might want to look into bitmasks

[dark drum]

Not sure if this helps. Top two are the names for the AI controller and Player controller. The next two are the pawn/character and what it's controller is. The second 2 are what the two controllers control.

[sweet swan]

I'm encountering an issue where small physics actors sometimes fall through the floor and this article (https://forums.unrealengine.com/t/landscape-physics-items-eaten-by-floor/675478/2) says I should be able to increase the thickness of the landscape but I don't see that option. Am I missing something?

[cyan bone]

Im doing a very simple rts. So basic collision -> Combat.
Though friendlies are overlapping.
What should i do in this case? Make them stop when they overlap?
Let them overlap? If i let them overlap then 100 units can be in the same place and becomes a mess

[hollow cove]

this may be a dumb question, but do parents construction scripts finish executing before their childrens

[dark drum]

The issue is, despite the player controller possessing a new pawn, it still thinks it controls the old character. Adding to this, the character still thinks it's controller is the player controller despite being possessed by a new AI controller.

[hollow cove]

i assume the answer is yes

[cyan bone]

yeah

[sweet swan]

depends on a lot of things

[dark drum]

They call when you call the orange call to parent node so you can have it before, after or inbetween.

[cyan bone]

then you execute your code

[hollow cove]

using spawnactor while casting to the parent from the child as the class input pin

[cyan bone]

or can execute code before and then call the orange node

[dawn gazelle]

Are you sure you meant to set the "Player Controlled" to true at this point? The idea of possession being lost should mean that this actor isn't player controlled.

[dark drum]

That's more to show that it was (at some point) controlled by the player.

[pliant zenith]

That's exactly what I was asking about xD

[dark drum]

slams head on the table
This makes it work. o.O what the.

[dawn gazelle]

This logic flow seems bit strange as well....
You've just possessed this actor with a player controller, then you're having the player possess another actor.

[glossy aurora]

They're in a user widget

[dawn gazelle]

Which would likely explain why this delay until next tick fixes it.

[dawn gazelle]

But they would be contained within something within that user widget. Like in the example I gave, I used a Vertical Box... There's different types of containers and some have different ways of getting their children.

[dark drum]

I would have assumed the possessed event would fire once the possession has completed but it appears to happen before it's completed.

[glossy aurora]

Oh, so like the canvas

Okay 😄

[cyan bone]

anyone got any tips?

i think i will let them overlap and then separate them sometimes idk

[dawn gazelle]

Maybe make them collide as well, but check if they are friendly or hostile and only engage if hostile?

[cyan bone]

well thats setup already. they are not fighting friendlies. The issue is they are overlapping the friendlies

so if they overlap it looks weird if they are 100 on top of each other

on the other hand if you send one unit and it collides with another, and you stop it, it breaks the flow of the units

so if you have 10 units moving the ones in back that touch the front units will halt

[thin raft]

Hi, I'm new to unreal and have a quick question. I made the third person camera get closer when crouching, but I also want it to get lower. How would I do this with blueprints?

[cyan bone]

you must move the camera in the Z

[thin raft]

But how do I get the z axis blueprint node? I want it to only move down when crouched and return to it's original place when standing up

It's probably very simple, I'm mainly an artist, so I dont know my way around yet

[cyan bone]

Set World Location

Camera ->

[thin raft]

Thanks!!!

[cyan bone]

ur welcome

[glossy aurora]

Why is the self reference node always present on my custom functions?

[cyan bone]

thats normal its the reference of the actor it belongs to

so you could call the function of another actor from this actor

[glossy aurora]

Docs said could use gt array size... it's not there 😭

[boreal crypt]

I want to attach a blueprint component to an actor, and have that blueprint component be able to find the first collision type object the actor has, so it can add some additional events on it.

Is there a common interface or tag that all collision types (box/sphere/capsule) share that I could use? Or do I need to look at each type separately?

[lofty rapids]

what you want the length of the array ?

[glossy aurora]

searching issue

[glossy aurora]

Yeah 😄

Figured it out lol

[dark drum]

Thanks for your help earlier. And yea it is a little strange. I'm trying out an idea I had where the player character is controlled by an AI controller and the player controller passes it's inputs to the AI. So using the player controller as a proxy for the AI. With this issue fixed my idea seems to be working now but time will tell what unforetold issues I might encounter.

I ended up simplifying it to this which seems to be working great now.

[boreal crypt]

Figured it out, needed to look for ShapeComponent

[main lake]

Is it possible to create a component outside of a blueprint ? Like I want to create a Main Menu component to be able to use it through multiple projects in the future instead of recreating it everytime

[unkempt warren]

I might sound like a novice when I ask this but, what's the proper way to destroy an actor?

Because I do this: Using the Interact interface..

And although it works.. If I tried do the interaction in same spot where it "was sitting" before it was "Destroyed" it throws an error claiming its "pending garbage or deleted item"..

[main lake]

You need to use interfaces.

[unkempt warren]

Uh, I thought I was? Did you look a the picture?

[main lake]

Oh my bad. The thing is you need to check if the hit actor with your raycast does implement the interface or not, and if yes then call its method "Destroy"

[thin panther]

You can do it however you want, in this instance that is perfectly acceptable to have the interactable handle it's own destruction

[unkempt warren]

I have done that already inside of the Linetrace function..

[thin panther]

You don't need a specific interface for ddestruction or anything, and who handles the destruction depends largely on the thing in question

Though to reiterate, in this instance it is perfectly reasonable to do it this way

(I'm assuming you're going to be putting your actual interaction logic before the destroy)

[unkempt warren]

Yes, its just I come across this bug saying the actor I am trying to interact with isn't valid. If I try to interact with the "Goldbar" again after I already destroyed it.

The Error message acts like it still there even though it was suppose to be deleted..

[thin panther]

show your line trace function

[unkempt warren]

https://blueprintue.com/blueprint/-3td3nhg/

[dawn gazelle]

You can author your own plugins. You'd create your plugin with whatever bits and pieces you want, then you can reuse that in your other projects.

[main lake]

But I'm not familiar wiht plugins. I wanted to create a component for my Main Menu but Components could only be added inside BPs and I'm not sure if Widgets can have component children

[thin panther]

Then get familiar with plugins

if there's a thing you want to do, and a system that solves it, go learn it

[thin panther]

Hm, that's an odd one.
I'd start debugging. Get some breakpoints and step through the nodes to make sure it's not referencing or calling through to anything you don't want

[unkempt warren]

So, I think I might know what it is.. So, the goldbar actor is a child of another BP.. could that be the issue??

Cause the code to interact with it is inside of the masteritem BP and not the goldbar BP which are both actors

Nope that didn't matter.. imma start debugging like you suggested.

[frosty heron]

The child will inherit its parent function. So Goldbar will have and run interaction function as the parents would unless goldbar specifically override the function

[unkempt warren]

It does not. Everything should be inherited from its parent like you stated.

[scarlet hedge]

Is there an easier way to contro a niagara system thru a UI widget ?

to me this feels convoluted, as I have to set up a BP with the niagara in it.

how can I just call to the niagara itself ?

[dawn gazelle]

"Actor Components" are only meant to be added to objects that are a child of the "Actor" class.
If you want to make a full on menu system as something modular you can "plug in" to another project, with a variety of widgets, player controller and HUD class all built in, then a plugin is what you make, and you'd extend from the base classes provided by that plugin to customize it as you need for the project. A single actor component wouldn't be able to fulfill what is required.

[main lake]

Alright, tahnk you 🙂

[thin panther]

Plugins are super handy. But a slippery slope :P.

Be careful you don't fall into the trap of modularizing everything into plugins and then you never actually end up making your game :P

[unkempt warren]

Fixed it, I added a branch to check if the actor was blocking the hit.. if not then don't do the interaction..

Not sure why the interact BPI is being ran to an actor that was destroyed though.. Why?

[main lake]

Is there an issue with using OpenLevel (By Object Reference) over Open Level (By Name) ? Most tutorials use ByName for some reason while By Reference looks better as it references your created Levels directly so it avoid easy typos.

[runic terrace]

I think it just comes down to preference and habit

[runic terrace]

Before calling the interact function, put an is valid node for the target actor.
My best guess would be that you're saving the hit actor to a variable but only when the hit actor is interactable. So when the hit actor isn't interactable it still tries to interact with the previous actor.

Try interacting with the table before taking the gold bar, if it returns a "accessed none" error that must be the cause.

[unkempt warren]

Not understanding it for sure but, checking if the actor was blocking the hit or not is what fixed it.

I did the try set, but not after it was destroyed. That might would work also.

I think "Destroy Actor" node doesn't get rid of the garbage collection or resource collection in the engine system until later on.. Like a couple of ticks or something..

[lunar sleet]

Destroy actor does not garbage collect automatically no

You can however call a garbage collect function if needed

[solemn agate]

quick question? why would the Set Constrained components not attach to the bone on a skeletal mesh. nothing seems to wrk

[misty patrol]

Anyone know the best way to go about using IK to stop my pawns hands from clipping through the floor?
Use case is a giant slamming into the ground and I want to prevent the hands from clipping into the floor but I'm not good with IK. I could use some guidance so if anyone knows how to and would like to help let me know, I'd really appreciate it.

[twin perch]

ok im using blue print interfaces and i need to return a value. however because ive got a return for some reason i cant make it into an event like my others ?

[finite hearth]

Go into the actor you want to return the data, double-click from the interface list under Functions, it will open up a graph where you can add logic. Plug in whatever variable you want to return for Current Level Spawn State into that return note.

[twin perch]

hmmm

[lunar sleet]

You’d have better luck in #animation

[twin perch]

that might work but i am having a second issue @finite hearth i appreicate your help btw thank you.

to get the target actor ... i am doing this this is the only way i know i can get the actor ... but i try doing this ... and the interface ONLY wants to keep self ...

i think ive figured it out

i had a few things screwy with my code, but i needed to click call in editor.

cheers for the help too that worked well.

[unkempt warren]

Eh, I fixed the issue by checking it doesn't hit the actor.. idk if that's a good solution or not.. but it worked..

[dawn gazelle]

Events can't have return values.

[twin perch]

its been solved sorry

[dawn gazelle]

All you appear to have done is convert your interface into a function present on the W_Spawn Level In World which wouldn't necessarily be the interface being called.

[lusty hedge]

how do i set a variable that is inside a struct

i break the struct. expose the variable . then what?

[timber sable]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Variables/Structs/#settingmembersinstructs

[lusty hedge]

its not working

This is driving me crazy

im adding 2 to the current value of the int "Amount"

i made it so when i hit f. it executes. and prints the result.

since the original value is 1. it should come out as 3.

AND it does!!! but if i hit f a 2nd time. its still 3!!!!

I dont understand

https://blueprintue.com/blueprint/4t8qk-00/

here is full BP

[remote meteor]

because ForEachLoop gets a copy of the struct, you will need to change it to get by ref by duplicating the original macro in your project

changing the get node to "by ref"

this way, changes to the struct within the loop will be propagated back to the original struct

why until now Epic hasnt added it by default is beyond me

[lunar sleet]

Maybe they’re protecting us from ourselves

[proven garnet]

Hey I'm having trouble with cast to but I'm not getting any error messages.

I want to click this BP and cast to BP_Score to start counting points. Problem is when I click the BP nothing happens. The BP is not destroyed and no sound is playing. Sound and destroy happened before I put in the cast to node. Also nothing is happening in BP_Score.

The actor reference on the cast to node is an actor object reference variable as the BP_Score has parent class: actor.

What am I missing here?

[lunar sleet]

How/where are you setting that reference

Also a cast wouldn’t rly throw an error but your cast failed pin should fire

Just to clarify: you can’t just create a variable of a certain bp class and use that as a reference.

I haven’t touched the procedural side of Control Rig tho what you’re describing sounds like a local vs global space issue. Maybe #animation can help more

[minor jackal]

Thanks

[proven garnet]

It's a reference in the BP. Guessing that's the issue then.

Is there a simpler way of just activating an event in another BP? Or is this the way to go?

[lunar sleet]

Well is what your clicking on an instance of BP_Score or something else?

[lunar sleet]

Cast is the simplest form of inter-bp communication. See 2nd to last video pinned in this channel to learn and actually understand how they all work tho. Lots of people misinterpret what casting actually does

[proven garnet]

It's another BP. I'm clicking on BP_PinScore (a cylinder) where these nodes are. And want to calculate the score in BP_Score

[proven garnet]

Yeah I've tried looking it up but a lot of the times it's just "thirdpersoncharacter" and that's not helpful

[lunar sleet]

Generally you prly wanna keep score in something centralized and easy to get like the game@mode or player controller

[lunar sleet]

I don’t understand what you mean. Did you watch the video?

[proven garnet]

No other videos

[proven garnet]

OKay I'll try gamemode

[lunar sleet]

Yeah, no watch that one when you have some time. It’s a bit long but you’ll finally understand how casting works.

[lunar sleet]

That’s only part of your problem

You can’t just set a variable class

You need to get that instance

So if you put it in the game mode, you need to use something like GetGameMode and plug the return value into the cast

A cast is a type check

It doesn’t magically talk to another bp, it checks the ref you gave it and if the instance is of the right class it lets you access it

Instance being the key word here, you need the actual object at runtime

[proven garnet]

Yeah I got it to work in another project while using game mode to cast to. But what's the difference here? I can get game mode but i cant "get class"?

[lunar sleet]

If you want to keep it as BP_Score, if and only if you’ll only ever have one BP_Score and it’s present in your world, you can cheat and use get actor of class Bp_Score. But in most cases you want to get the actual precise ref to that object

[lunar sleet]

No, GetGameMode gets you the instance of your current game mode that is spawned at runtime

You would need a function that gets you the instance of BP_Score, which like I said you can use get actor of class if you’ll only ever have one of them and you placed it or spawned it in your level. Better to use centralized stuff that is easily accessible for score and the sort, i.e. GameMode

And watch that video

Else you’ll keep stumbling through every time you want to talk to a bp

[proven garnet]

I'm going to watch that video but man THIS felst SO good:

It just worked

Haha, I know I don't know how complicated I might have made stuff for myself down the line

But this felt so simple

I'll watch the vids

Thanks!

[proven garnet]

Just a quick question in the instance of the BP. The wildcard object ref in the cast to node, why can't I just reference the instance there? The BP_Score is not searchable.

[lunar sleet]

Yes, it’s a neat little cheat but don’t start using that every time, you’ll just end up with more bugs. You usually need to be more precise than that, so you need to actually interact with the object and thus obtain that reference. For example, if you want your char to open a mailbox, you would have it overlap or trace to the mailbox, get that overlapped/hit actor result, and cast to see if it’s an actual mailbox, and if it’s the mailbox you want to open, not just any mailbox in the level (because that’s what get actor of class gives you)

[lunar sleet]

To clarify, an instance is an object of a class that is created in your world during runtime, you cannot search for it because the instance is not created until you hit play

And also that’s not how references work

If you want to see an example, hit play then go back to the editor and select the debugging object on one of your bps. You’ll see something like BP_ScoreC01 or such. That is your instance, and thus you cannot just look it up before it has come to exist

[proven garnet]

Ah okay

That makes sense

Little by little

It makes sense

[lunar sleet]

Takes time but that video helped me understand comms a lot better

[proven garnet]

I'll definitely watch it asap

In the meanwhile though:

[lunar sleet]

Add another BP_Score to your level and get actor of class immediately breaks, because you can’t choose which one you want to talk to

[proven garnet]

Oh I'll try that

[lunar sleet]

Cast is one of the greatest tools we have, once you understand it, you’ll change your own mind

[proven garnet]

Haha yeah of course, I just need to wallow in my own stupidity 😛

And yeah it breaks if I have another BP_Score in the world

Which also makes sense

But wouldn't I get an error message saying it doesn't know what to do?

[lunar sleet]

Most things don’t throw errors at you, they’ll just fail silently, and you have to do the other 50% of a gamedev’s job and debug

[proven garnet]

Haha fair enough 😛

[lunar sleet]

In the mailbox example I mentioned, get actor of class would just give you the first mailbox the engine finds in the world, so its uses are limited

[proven garnet]

Also makes sense

I look forward to the day I understand cast to. Gonna be a good day.

Thanks for the help!

[hidden cedar]

I have no details on my charactermovement component. how do i fix this?

[pallid swallow]

Hi guys ! I am kinda new, I want to update a textbox value in Widget value when a game instance event occurs why this doesnt work ?

[frosty heron]

Use set Text function , instead of changing the variable

[thin panther]

Revert in source control

[pallid swallow]

Thank you for your answer, may I know where and how ?

[thin panther]

If you haven't set it up, set it up now, and pray for an autosave hidden somewhere

Otherwise, remake the bp

[frosty heron]

get your text box -> Set Text

[pallid swallow]

In the game instance or the Widget ? I genuinely dont see the difference between what I have done and what you tell me

[frosty heron]

your TextBox

use Set Text Function

might not be the entire problem but it's a start

[pallid swallow]

Thank you !

there's a lot of Set text functions

It didnt solve the problem though I thought it was working but no

[frosty heron]

Setting a text is a very simple process

you get a reference to your text box

then you call the set text function

if that don't work you will need to debug and find out if you are calling the function or getting the right ref

[pallid swallow]

This is the problem I think. I want to create a widget, append it and set it text

[frosty heron]

Then create the widget, I see you are doing chatbox. I totally won't recommend multiplayer project if you are early in game dev business

[pallid swallow]

It's just a simple twitch integration with websocket

[frosty heron]

You create widget -> Set the text on the newly created widget -> Add it to the chatbox widget

[pallid swallow]

Do you know how can I get the ref of a newly created textblock because the step 2 is the problem. The item is added but without the value I provide.

[frosty heron]

well where's the newly created text block?

[steel shadow]

Hello, I'm having an issue where my root motion dodge animation is overwritten by a tick from a lock on, anyone has this issue and knows how to have the root motion have priority ?

[frosty heron]

I don't know what chat entry is

if that's where the text box reside then you can get a ref to the text box by getting a ref to the Chat Entry

W Chat Entry -> Text Box -> Set text

[remote meteor]

during the roll, you want to temporary disable the lockon, that adjusts the character rotation

[steel shadow]

Is there no other way you think ? Like forcing a root motion ?

[remote meteor]

how did you implement the lockon? on tick -> set actor rotation?

[steel shadow]

yeah basically

not tick but looping but same problem

[remote meteor]

you would want to keep the portion of the camera adjusting to the focus target

but during the roll, you want to temporary stop setting the character's rotation

[steel shadow]

Ok I think I may have an Idea

[remote meteor]

root motion will always follow the character's rotation

it doesnt override it

[steel shadow]

Okey thx, I'll figure something out then 🙂

[pallid swallow]

For some reason it (bp) still gives me the following result(screenshot)

[remote meteor]

ListView?

list view requires user to use its flow to setup from the object

[remote meteor]

you do not need to create widget manually when it comes to ListView

[pallid swallow]

What should I do because it seems that the widget is still created though

[remote meteor]

read the tootip already?

[frosty heron]

Just use a vertical box for chat imo

[pallid swallow]

Okay

[remote meteor]

if you have alot of message, ListView is good

its purpose is for that exactly, not to create 1000 widget if you dont see 1000 at once

[pallid swallow]

I basically have a Twitch chat so I will have a lot of widget, I was planning on having a fixed size and delete them when theres a new I dont know which solution is the best

[remote meteor]

The usage of list view is different than usual widget, you will have to create object for its data, and ask the ListView to present the data.

[pallid swallow]

Thank you for this, I will see what I can do, I managed to do it by replacing to Vertical box, but I might stick my nose into ListView because it seems more appropriate to my case !

[woven shore]

so if we have a rigged skeletal mesh like that shapes, the physic will do the collider right?
or we could have the regular mesh collider for skeltal mesh

[remote meteor]

if you have the time, take some time understand what is a ListView, and see if you would like to go that extra miles of making use of it.

[remote meteor]

a skeletal mesh gathers its collision info from its physics body, usually it is generated during the import of the skeletal mesh, but i know you can import it together with the 3d software you use.

you can edit the collision shapes in editor by going to its PhysicsBody asset

just for clarification, PhysicsBody =/= it runs with Physics

[woven shore]

yea right, it's just the physic collider would not be as well shaped as usual collider, the character may be hang if stepping into it,
how to get better collider for skeletal mesh tho

[pallid swallow]

Just a normal UObject ?

[remote meteor]

or any already existed objects that contains the data you would want

[pallid swallow]

And how did you manage to put such event ?

[frosty heron]

override the function, it's probably something from the tree list

try selecting that then look for the event

[pallid swallow]

I don't think so

[frosty heron]

I see it's probably interface then

[pallid swallow]

Is there any reason why it's called "object list entry" ? on his because mine is "user list entry"

[frosty heron]

you are not using the right class then

you want object list entry

https://forums.unrealengine.com/t/what-is-userlistentry-list-view-interface-for/625345

[pallid swallow]

I don't know why I am not using the right class, I created the entry according to the listview

[steel shadow]

This is an infinite loop for unreal and I don't see it does anyone know ?

[frosty heron]

Open WB_ChatEntry

look at the parent class

screen shoot it

[frosty heron]

@steel shadow cursed

[timber crystal]

Hello friends, can someone help me with a simple code, I'm too new for this...

I want a different animation to be played when the character is standing and shooting. Yes, I know I should use locomotion, but that's a different topic. I think it could also work that way, so if anyone wants to help me with that, I would be very grateful. I already have something begun

[steel shadow]

😦 There is still a way out I guess but the dodge branch is the issue then

[frosty heron]

i never use tree list but for a start, use UserObjectListEntry instead what you have right now which is UserListEntry

it should be the reason why u don't see the function that needs to be override

[timber crystal]

Can someone explain to me why this doesn't work? I want that when the speed is at 0 and the character shoots, a different animation plays...

But what's wrong with that, apart from the fact that I don't use any transportation

[dark drum]

I would imagine it's because you check if the velocity is less than 0 which unless it was moving backwards would never be true.

[pallid swallow]

I didn't know about that

[timber crystal]

yes, I thought of that too, what would you recommend?

[dark drum]

Check if it's equal to 0 or nearly equal.

[timber crystal]

i try it also with zero but same issue with both nearly and zero

[dark drum]

there's an node for nearly equal, its different to the equal node.

[timber crystal]

ok let me see thanks anyway if it works or not 🙂

[timber crystal]

same problem also with 0,1

[lofty rapids]

there is a chance you stand still, and the bool gets set to false, but true plays ?

for some reason i feal like the set for that boolean should be later on, not sure if it matters

[timber crystal]

u mean change the brach connections?

[marble tusk]

If that is the only place you're setting the Boolean, then that's why it doesn't work. If it's false then it won't ever go down the true branch to ever check if it should be true or false

[timber crystal]

ok let me check it out

[marble tusk]

Might not even need the Boolean variable and could maybe just plug it directly into the branch

[timber crystal]

GOD BLESS YOU

it works without the branch

haha nice THANKS!

[remote meteor]

this part could be infinite loop, you should use tick for these job though

oh im so late lmao

Parenting and a little bit of name more then likely

Bones, the skeletal mesh has bones. Some of the bones have parents. Actually all of them have parents.

Like your mom/dad has a parent which is your grandma/grandpa.. Kind of thing same for the bones.

[native canopy]

my code is simple, but why after actor translate the actor falling after a few second

set movement mode is not working
