blueprint

[ruby egret]

I remember I did it years ago by setting something but I've tried googling and I can't figure out how I did it

[west yoke]

@leaden sun Yeah that sounds like something the constructor should be handling. Or BeginPlay if you don't need it at instantiation time.

[leaden sun]

Yeah for sure. Basically trying to make a Sound Cue component which grabs a static mesh from it's parent and plays some sounds based on impacts that the parent static mesh makes. I could instead make a static mesh component, attach the sound cue via constructor/beginplay, and then do all the logic inside that component instead with no "grabbing of references willy-nilly"

[leaden sun]

yup ^ I think this is probably what I want

I hate chucking comps in in beginplay, I love the visual nature of components in the hierarchy in the viewport but unfortunately it's not really possible here 😅

since I for sure don't want to be using child actor components 😛

[dawn gazelle]

It should appear in the variables section of the blueprint graph.

[ruby egret]

When I go into graph and click the eyelid it is not made public

Set brush from texture

Thank you

Fucking googled it for 20 minutes and couldn't find what it was called

[dawn gazelle]

There's a few other Set Brush From... options in there when referencing an image widget.

Texture I think is the one most commonly used 😛

[scenic swift]

I'm trying to figure out an ideal system for an "animated moveTo" in UMG, but neither seems to make much sense to me...

• in Animation Timelines, I can't specify a transform to an arbitrary variable xy point; just the same location every time.
• if I Set Render Transformer, it on'y allows instantaneous moves, and since widgets aren't actors, I can't have a "smooth"ly animated transform?

I feel like I'm missing something...

[hard charm]

Guys, a question, I want to do a mechanic to get sparks where my sword hits. My question is better to use the weapon's rayCast or use the weapon's collider and then take the point of impact. Thank you

[trim matrix]

at the end i managed to get a pretty good result with these two macros

[brazen pulsar]

So I'm trying to make it so when a person talks to someone, it changes the textbox to one made for the character. I have .pngs for each character's box, but switching between them is proving difficult

As in, I literally have no clue what I'm doing

[trim matrix]

you need to create a brush from the png of the text

and connect it to the return node

[brazen pulsar]

how I do that?

like what node creates the brush

[trim matrix]

it's a bit of a mess but i have the image that gets the variable i set

[brazen pulsar]

I just realized I haven't eaten all day. I'll brb

[brazen pulsar]

I realized it’d be way easier to do it another way, specific to the problem I’ve got, the second I stood up. So nvm

Basically each dialogue tree is a widget, and I already duplicated them like 5 times so I’m just gonna use different widgets for each character

[clever ridge]

Hey all, new developer here trying to get some help with a troublesome blueprint.
I have an actor that I’ve set the transform of in a function. Everything works great until I get down the execution line to a function call for a function in a separate actor’s blueprint. Somewhere between calling the function and executing the function, the transform of the actor I just set shifts by a couple units. This is incredibly annoying since I’m trying to set it to a very specific location that if shifted by a couple units makes it look strange. It’s not consistent either. Every time I try to debug the actor shifts differently and randomly.
I’ve used print string nodes to narrow down the problem to this specific function call, but I just don’t know what to do about it. I appreciate anyone who takes the time to help me with this.

Where the function is called:

the start of the called function:

I can give screenshots that show what it's doing in game too but don't want to spam

[solid needle]

hi all, i was wondering cuz i never used interaction widget, how to set the text inside it from the player character?

and set this, not sure how :P

[daring laurel]

Anyone could link me to a tutorial on how to script splines to randomly generate their point coordinate ? THANKS

[trim matrix]

the screenshots you showed unfortunately don't give much info on what could the problem be

show the insides of those functions

[sudden hare]

any chance you're spawning an actor (and have "adjust if colliding" set?)

could be UE trying to stop them colliding

[daring laurel]

Heyyyyyy ur a boss

I was trying to decipher this blueprint i found

https://blueprintue.com/blueprint/4ebxc8t_/

Lmao

[clever ridge]

No I'm not spawning any actors with my scripts. Everything is already in the level before I run the sim. Appreciate the suggestion though 🙂

[kind atlas]

Man we really need a channel for animations

[trim matrix]

#animation true

[kind atlas]

Yes that’s content creation not programming

Well shit that could be double meaning

Is it for showing off content or for creating content

[trim matrix]

It's for everything related to animations i think

[kind atlas]

Oh okay

[trim matrix]

some channels are kinda dead here tho

[daring laurel]

@solid needle Yo Harambe, it looks like ur technique is missing a keypoint

this blueprint does nothing for me 😦

[carmine scaffold]

can someone help me with this accessed none issue?

[solid needle]

uhh i assume you want to creat them, this one literally makes a point in a random area

[daring laurel]

Yes, the idea is to generate procedural villages

[solid needle]

ohh right, let me try find how to create them for u

[daring laurel]

I can make the spline to procedurally generate the meshes

but only from the Editor

I would like to script the spline to have different point cooridnate everytime the map is playing

[solid needle]

lol

[daring laurel]

😄

[solid needle]

harambe

[carmine scaffold]

?

[daring laurel]

I get a headache by looking at the picture only 😄

[clever ridge]

Here's my entire ReleaseCoin function excecution line after I got rid of all the print strings, but like i said the problem is right where the Update Scores and Scale function is called.

[daring laurel]

How comfortable are you with UE5 ? Would you consider yourself skilled enough to be paid for teaching ?

im looking for a genuine guy who could teach me

im ready to pay 300$

[solid needle]

i mean, im in uni for game designb ut i dont think i have a tutor skillset

[carmine scaffold]

its legit the only thing stopping me from packaging

[clever ridge]

I can show you the inside of the called function but print string nodes immediately at the start of that function print the shifted and incorrect location for the placed coin

[daring laurel]

I see I see.

My goal is to make a Procedurally Generated game where you need to harvest ressource and sell them to a scrapyard in a zombie apocalypse

[solid needle]

i am focused on the logic part of unreal anyways :P i probably dont offer much more than matt aspland tutorials do

[daring laurel]

you have a mobile base ( a bus) wich you can modify

I want to ride the hype of this new game genre : Lethal Company

created by 1 single man

[solid needle]

lethal was a single dev?

[daring laurel]

yeh

[solid needle]

crazy

[daring laurel]

as i heard of

[solid needle]

the best part of lethal is teh VOIP with being inside theres echo

and hear echo off walls

[daring laurel]

yes 😛

i would like to build a similar game but with zombies and a mobile base station

[trim matrix]

well... show that other function then

[solid needle]

sweet

goodluck :P

[daring laurel]

I am more of a 3d artist tho

I barely begin in programing 😄

[solid needle]

ah sweet, im opposite, 0 artistic knowledge

[daring laurel]

team-up with me and lets build this game and become rich by 2025

[solid needle]

i know how to use blender but i dont know how to make something yk, good?

[daring laurel]

[solid needle]

ah man, i got too much deadlines with uni to have projects

[daring laurel]

lol

i need more brain power

I dont understand your blueprint thing tho.. it doesnt work

[clever ridge]

Here's that function plus the GetPlacedCoinsTransform function at the beginning of it

[dawn gazelle]

I think you have references to your PlayerPawn variable within your animation states and you're not checking if they're valid before using them.
If this is the case, then ideally you would be pulling values into the animation blueprint from the pawn in the blueprint update event and then having your state read from those variables rather than directly from your pawn reference.

[solid needle]

it only creates a spline point

does look like you have generation or anything, it just makes a random point randomly in the world

drag it in the world as well :P

[daring laurel]

The generation seen in the video is a pre-placed spline in the editor

not a generated one

the generated one should be the empty spline shown

[solid needle]

yeah, it only adds one point lol

[daring laurel]

ok so this should be better

[solid needle]

no

dm me, lets not flood this chat lol

[daring laurel]

kk

[cerulean stratus]

how can i get the vertexID of the currently selected vertex while in modeling mode?

[trim matrix]

Anyone ever had it where the delegate even though being called and something binded to it doesn't seem to trigger

It's confusing me a lot and don't have clue what I'm doing wrong as it works fine if not in a particle situation

[lament ginkgo]

Maybe someone can help me - I'm trying to make it so that a player looks at a screen and hits Use, the camera then blends to the screen and if you hit escape, it blends back. Basically when you hit interact, I lock the controls, do a set view target with blend over X seconds, delay x seconds, then possess the new pawn and unlock controls. In the reverse, it's lock the controls, blend back to the original player character over x seconds, delay x seconds, then unlock.

The problem I have is when you return to your character, as soon as the blend is done, the view snaps up, rather than finishing with your eyes directly on the console. Do I maybe need to save the original camera data before doing the blend and then blend back to that? How would I even do that? Is there a better way?

Ends up looking like this.

Should note the console view, camera panning is locked (there'll be a UI overlay you'll mess with like a phone).

[daring laurel]

This is looking sick, idk how to help you. But this is my question to the chat:

Hello, I am generating scripted spline and I wonder if anyone has an idea on how to build the spline in a way where it wont intersect

this is the spline code so far

or bp if u prefer

[wary skiff]

hey is there anyone here who might be interested in taking a crack at a system implimentation problem. I know exactly what i want to do and the logic behind it however not sure how to actually make it.

More details

Building system with a simple support mechanic

need to be able to check to make sure object is supported, attach to object, inherit support value if building vertically or support value -1 if building horizontally.
before building would need to make sure support value is greater than or = 1 at least

i have more details but to anyone interested in helping either @me or DM me

[daring laurel]

maybe if you offer some buckaroony people will be tempted more 😄

[wary skiff]

im open to paying as well

[daring laurel]

Good luck, i'm a fellow noob

[ruby egret]

Anyone know how I can access a public enum I had on a widget blueprint from an On Drop event? I have the enum inputted to the event as the tag. I can print the enum that comes out of the On Drop Operation as a string but I cant use it in my interface.

[versed sun]

you can get it from the Payload

err, make your own Dar Drop Operation

Inside the Operation, make a Enum, Expose on spawn

[dawn gazelle]

you were right here. You can pass in the widget into the payload of the basic drag and drop operation.

[versed sun]

Set it on your Drag Started

and grab it on your On Drop

[ruby egret]

My only options for the payload where I create my drag and drop are textures for some reason. I'll make my own drag drop with enums instead of textures.

Thanks

[versed sun]

like nyahhh?

[dawn gazelle]

Yeah that'd be if you fed the widget in... That's why I deleted what I did as you were explaining using a custom D&D operation

[versed sun]

its been a while since I used them

[stray halo]

is a mutligate supposed to do all out comes on each pin or just one?

[ruby egret]

Got it working! Can finally push this to my repo and go to bed.

[true valve]

Anybody knows the fix for the City Sample? When I try to drive the car, it goes flying. Probably collision issue or destruction issue.

[floral patrol]

Getting an error when I possess/unpossessed a vehicle. I have a foliage interaction system set up in the level bp and am getting accessed none when I use the vehicle. Not sure of the best way to fix it. If anyone has any tips or can point me in the right direction I'd really appreciate it.

[dawn gazelle]

Get Player Character tries to return a literal "Character" reference which your car probably isn't.

You could try changing that to get player pawn

[floral patrol]

Thank you!!!!!! It worked!

[dawn gazelle]

Also just a suggestion for some optimization, rather than always ticking and checking what the game mode is, on begin play you could start this actor with tick disabled and if the gameplay is the one you want, you can enable it, allowing the tick to do its thing. Additionally, it's not great to use a string comparison. You're better off getting the class of the game mode and checking that directly.

[floral patrol]

Thanks, that was just a blueprint I had found to incorporate the brushify foliage effects.

So what impact do you think that has had on game performance the way it's set up? Jw I'm still learning

[edgy ginkgo]

I am having trouble implementing something into my game, it is multiplayer but it's done with blueprints and is local multiplayer. I am attempting to make a character select where upon game start four input receivers and four local players are spawned and are set to possess all of the input receivers. The input receiver simply detects a player pressing the start button and spawns a character and lets the player controller possess it.

Sadly I have an issue. Regardless of the controller I use the first player is spawned upon pressing start but no additional player controllers are spawned. I will post the blueprints used bellow. If anyone thinks they can help I really need it. Thank you

Game Mode Blueprint that spawns the receivers and possesses them.

Please help!

[dawn gazelle]

It's minimal overall, but it's something to keep in mind when using tick. You can turn it on and off rather than just running it always and gating it with a boolean like that. It's definitely more of a performance save if this was happening on several actors in the world, but seeing as this is your map blueprint there'd only ever really be one map.

[floral patrol]

Oh I see, I changed it like this

[loud cipher]

Whats the difference between using a blueprint interface vs a custom event in the same blueprint

[frosty heron]

If u are using interface in the same class you are probably not using it right

Just call the event directly?

[dawn gazelle]

Interfaces are meant to be a means of declaring a function that can be implemented across different classes.
Eg. I can have an "Interact" interface function that I implement in a door and a light switch. My implementation in the door causes it to open, where the implementation on the light switch turns on a light. All I'd need to do to call it is have a reference to either a door or light switch and call the interface with that reference and they'll do what they need to do, and it doesn't even need to be casted - as long as the reference you have contains something that implements the interface then it'll work (ie. if you have an "Actor" reference storing reference to a "Door" it should work). If the referenece doesn't implement the interface, then nothing happens.

An event being declared in a class means your reference needs to be of the exact type (or a parent of that has the event) in order to be able to call it, so you may need to cast to several different classes if they don't share any common parent in order to call events across several classes to do something similar to an interface. Eg. I could have a "CauseDamage" event declared in my "HeroCharacter" and in my "Door" classes, but these classes don't really share a common parent - in order for me to call to the "CauseDamage" event on either of them, I'd need my reference type to be "HeroCharacter" or "Door".

[edgy ginkgo]

I take it no one has leads

[elder lodge]

i think your problem is just too involved to get a quick forum answer

at least for me, maybe someone else knows the instant answer

You should go to #multiplayer

[dawn gazelle]

I'm not sure why the double loop here.

And then here you're creating a controller, but not using it and getting controller by index instead, you should be able to feed this directly into the possess node.
Also I think you need to hook in the return value from the create player node into the Player Controller Array at the end.

[mild basin]

if you want you can take a look at my example project on GitHub : https://github.com/Thor110/ABC-UE5 I also have a UE4 version and a UE5.3 version, all of which have multiplayer support and everything is in blueprint, though it's not very fancy or finished.

[edgy ginkgo]

so the first loop sets the array element by the number of the array it is currently on, the second loop uses that array number

[edgy ginkgo]

let me try this I think you mgih be onto somethign

in order to make sure the array matches the spawn name (basically to make sure the player spawns at the correct place) the first loop sets it then the second loop runs through all values until one matches to spawn it

[elder lodge]

can't you just use that index number directly? do you use it again later?

[dawn gazelle]

I think it's to make sure player 1 starts at the player 1 spot, player 2 at player 2 spot etc.

[edgy ginkgo]

correct yes

and all of these input recievers do spawn in in the correct locations I confirmed this by giving them meshes

I think the issue is that they are not all being possessed or when one actor spawns all controllers are unpossesed

since any controller can spawn player 1 but then all controllers controll player 1

[edgy ginkgo]

tried these changes but it seems to be more broken now

player 1 now will not even spawn

which seems odd since I think doing the method this was makes more sense

the error under further inspection is from this node

it says it is getting node from the get player controller return value

[dawn gazelle]

Just directly call it from the create player node, no need for the ID#.

[edgy ginkgo]

before it had this error appear two times (which may be because I only have 2 controllers plugged in) but now it appears 4 times

oh

let me try that

even when doing that player 1 does not spawn in

[edgy ginkgo]

my thought is perhaps index is not being set correctly

[dawn gazelle]

Well, part of the problem could be because player 1 already exists?

So player controller 0 doesn't require the creation of a local player.

[edgy ginkgo]

correct but in my game defaults there is no player pawn for it to control, as those are spawned in this way so it still needs this blueprint to posess

but maybe create local player fails

that's a good point

[edgy ginkgo]

okay so I have been testing things, I went back to the original code for a second after saving my changes since that seemed to be a bit closer to working I turned on split screen and have confirmed only 2 inputs are being possessed

[edgy ginkgo]

this issue happens if we plug in the create local player return value but does not if we do not as if possessed uses the ID from index it will always possess even player 1

I put this back to default -1 to see if it fixed anything and it did not

the difference is If I use -1 for create local player it makes 2 split screens and if I use index it makes 4

not sure why this is the case

wiat

hold up

https://blueprintue.com/blueprint/c1zt5kww/'

with my blueprints set up like this I am no longer getting the possess error which means all my players are possessing correctly

Unfortunately this has not fixed my problem, so I believe the problem lies in the player spawning in that case

[haughty egret]

Does anyone know what causes this in blueprint diffs?

[edgy ginkgo]

I have found as a follow up what is not my problem

all input recievers are possessed by players

but still only one spawns

also when I spawn in one layer it shows the other players are still possessing the input recievers

is it possible both of my controllers are player 1 for some reason

[mild basin]

you could print string the player id from each controller via a button press?

[edgy ginkgo]

let me try that

good call

[mild basin]

😇

[edgy ginkgo]

sadly it's not printing for an unknown reason

I now know the reason

so yes both controllers come back as controller 0

that would be the issue lol

[mild basin]

at least you know for certain now though

[edgy ginkgo]

now just need to figure out how to fix it

that did help I really appreciate it

[frosty heron]

????

[mild basin]

at a guess, given that you don't have a server structure, it would be something along the lines of not checking and assigning the relevant player id when they join in the first place. As something needs to keep track of that

[frosty heron]

Local multiplayer is not really network by nature unless a support is given

It's the same as single player

No server what soever

Unless u want to support remote play

[mild basin]

Right, but I think the actual problem for them is that all connected controllers are possessing id 0 and therefore spawning at the spawn point for 0

[frosty heron]

Also what is that playerindex? Your made up int?

[edgy ginkgo]

not quite, the others refuse to spawn since they both only control player 1

[frosty heron]

I don't know about local multiplayer, not something I want to venture. But obviou step is probably to figure out spawning controllers and saving their references then knowing how to map inputs

[mild basin]

ah, well I haven't followed the problem in it's entirety and generally prefer to give methods and thoughts that might direct users to discover problems for themselves as opposed to outright solving them for them.

[edgy ginkgo]

player index is the number that is passed into the input reciever by the game mode on spawn. it essentially tells it what number it is

[frosty heron]

I don't know that Playerindex variable doesn't even follow unreal naming convention so I bet it's a variable u declared

[edgy ginkgo]

I mean you've helped I appreciate it, just clearing up any misconceptions about the full issue!

[astral orchid]

Quick question, it is possible to give an ABP, or more specifically the AimOffset, only when you give the character a property?

(Like, a character will only get the AimOffset when it has the gun, or sword, etc)

[edgy ginkgo]

it is declaired but it should change for each controller as it's a number that differs depending on the number being possessed

[astral orchid]

Hold on rq, what are you trying do to here?

[mild basin]

glad to be of some assistance, best bet is usually just to go through everything again and re-think the problem through, as troublesome and time consuming as that can be.

[mild basin]

definitely possible.

[edgy ginkgo]

I mean this is just a snapshot of where I am getting one variable

https://blueprintue.com/blueprint/c1zt5kww/

here is the full thing but this is the part that works

[astral orchid]

Then what is the best way? I don't want to do linked anim layers, cus it sounds like a chore. I feel that changing the ABP itself when the weapon is given will be too cumbersome

Is there a weapon to just impose the AimOffset once the weapon is given?

[mild basin]

perhaps try tracing out the array index of the player start array and checking everything when joining the lobby, but in part what you do next to solve this problem all depends on how the entire system is setup.

[astral orchid]

I mean, what is it you want it to do?

Like, what's the end goal here?

[mild basin]

the best way? no idea.

[astral orchid]

damn, is there any that is like this?

[edgy ginkgo]

I am trying to spawn players, however both my keyboard and controller are apparently assigned to player 1 and so I cannot spawn any additional players

[astral orchid]

keyboard?

I mean, if you're trying to spawn players, i'm sure there's a better way then that

[astral orchid]

isn't the input component supposed to be on the character?

[astral orchid]

So, is there just a way to apply the AimOffset to the character only when it's given to said character?

like applying a weapon mesh

completely seperate from the original mesh

[mild basin]

really depends how you have everything setup, realistically you are going to require a check to see if they have a weapon equipped that requires an aim offset variation.

I'm not certain on the specifics tbh, you just asked if it was possible, to which the answer is almost always of course heh

[edgy ginkgo]

it works since it does spawn 4 players and they all possess properly, the problem is a controller issue, I just need controllers that connect on different player inputs...

[astral orchid]

are you playing as "standalone" or "as a client"

[edgy ginkgo]

this is non online multiplayer so I am playing standalone

[mild basin]

might be worth making a new project and just setting things up to tinker with separate from your main project

[astral orchid]

Let's say theoretically, I have a character's ABP and it doesn't have an AimOffset. And I have a weapon class that will apply an AimOffset to the character.

So what should happen is that the AimOffset from the weapon should "overlay" or "override" over the original ABP; it applies the AimOffset on top of the ABP.

[astral orchid]

Ok, why don't you just skip the Integer Index variable, just use the Array Variable directly.

[mild basin]

I hardly dabble in animation blueprints tbh perhaps check : https://www.youtube.com/watch?v=jHM7JzsNyvQ or some other similar tutorials

[astral orchid]

And the array is an Array of Player Controllers

[astral orchid]

Alright, thanks for your time

[mild basin]

gl

[edgy ginkgo]

well found out something

turns out this version of unreal just assigns both controllers to 0 regardless

[astral orchid]

I guess update to a better version

should fix it

[edgy ginkgo]

can you change your default project's version by updating to a new unreal version or will it just cause issues

[astral orchid]

it shouldn't usually

you could do a rebuild

like, delete the binaries, .sln, intermedieates, etcs

and then starting the project again

it should give the option to choose which version to build it in

[edgy ginkgo]

I am kinda deep into this project actually, unfortunately this is one of the last features I need, I might just get a new controller...

[astral orchid]

you're not gonna delete the whole thing

just the data files, keeping the sources, content and config and uproject files i think

[edgy ginkgo]

oh I see

[astral orchid]

then open the uproject file, and it should allow you to build the thing in a different version

you'd still keep everything

[edgy ginkgo]

I'll try updating to 5.3.2 then

[astral orchid]

just remember

do your research

make a back up

i'm not gonna be responsible if you lose your project

[edgy ginkgo]

yeah no worries I appreciate your help

[silent kestrel]

Kinda frustrating issue: I'm following this (https://www.youtube.com/watch?v=17D4SzewYZ0) guide on a custom movement system. One of the last steps is to attach the new custom CharacterMovementComponent to a pawn, however i'm at a loss for how to do this, and he kinda glazes over it in the video. Asked around in another server and nobody there knows either, google couldn't bring up anything. How exactly can you do this?

[frosty heron]

I am not gonna open the video but why do you need to "attach" cmc? If you gonna use cmc you should derive from character in the first place which already have cmc.

To replace your cmc to your custom one simply go to the detail panel

[silent kestrel]

That's where i'm running into the issue. For some reason, mine isn't showing up in the dropdown in the detail panel.

[frosty heron]

Ur cmc class is in cpp?

Make sure it's compiled

I have no issue with extending cmc

[silent kestrel]

Yep, it successfully compiled. I tried restarting Unreal, refreshing the visual studio project, and nothing worked.
Header (https://hst.sh/eceherudor.cpp) and cpp (https://hst.sh/alodovaqar.cpp) files for the movementcomponent are here, and here are the ones for the character: (https://hst.sh/liwakidogu.cpp) (https://hst.sh/alodovaqar.cpp)

[frosty heron]

Can u share image file

[silent kestrel]

Sure, one second

[frosty heron]

Check if you derived your cmc class from cmc base class

I just opened the turorial and for the record, I am following the same one

[silent kestrel]

I think that's the right base class. These are my character classes as well:

I wish there was an error message or something, anything is better than it not working without giving any reason why

[frosty heron]

Might have to rematch some of the steps and perhaps asking in #cpp. Can't help u now as I don't have editor on me but I got it work on my end

[silent kestrel]

I'll try that then, thanks

[edgy ginkgo]

as an update that fixed it

needed a second controller

(don't mind the messy camera lol)

[woeful yoke]

Is it possible for BP object to not receive decals? I seem to find no answer to this

[toxic summit]

Not for a "BP Object", but any PrimitiveComponent-derived component has a ReceivesDecals setting you can uncheck.
In other words - go to the mesh component (and any other rendered components) of your BP and uncheck ReceivesDecals

[edgy ginkgo]

New problem

now up to four players will spawn in the game, however they will all only control the first player character

[edgy ginkgo]

I fixed it too

it is working

hey, in our 3rd person game we have a camera setup where each possible camera is on one or more several springarms with different positions, rotation and length setup
this handles wall collisions for individual cameras fine, but we're also lerping between these cameras depending on player state in the PlayerCameraManager and when that happens there's no collision check and thus the camera can go through walls while moving from camera A to B
is there any solution to this that won't involve remaking our entire camera setup again? like some way to do additional collision/avoidance calculation in the PlayerCameraManager when calculating the final camera angle?

[mental trellis]

Instead of having multiple springarms, have a single springarm that lerps between different positions.

[thin cradle]

We'd still have to redo the camera setup as each camera is a child of each springarm and also one of our cameras chains 2 different springarms so that wouldn't be covered

[potent wedge]

Hey guys, i'm trying to create an ammo system with blueprints, does anyone have on i can borrow or possibly look over so i see where i'm going wrong?

[mild basin]

there's an entire firing system provided in the existing sample projects from unreal. Perhaps you need to go and start with some basic tutorials first.

[potent wedge]

Alright cheers

[mental trellis]

Springarms are what do the collision checking. Lerping between them involves no checking. So either do it manually or lerp using a springarm. Those are your choices.

[crystal epoch]

Hi!
Does anyone know how can I sort (and update) the elements of an array based on a stat? I want to make a turn based combat where the speed determines who attacks first, but i'm failing to properly sort the array based on the stats, any clue or resource that I can check? Thank you in advance 🌸

[noble crescent]

Currently Making an RPG and each Party Member has a lot of Data to save.
So I'm wondering if the best way to handle this is to create a structure with everything that needs to be saved.
Then, within the Save Game Object, create a Map with a String and Structure. The string being the Member's name.

[mental trellis]

Sure, why not?

[noble crescent]

Just wondering if it's fine to have all of that data, confined to one variable.
If it'll cause any issues.

[mental trellis]

Nope.

[noble crescent]

Thanks. 👍

[shadow holly]

Hey, does anyone know what the most optimized way of creating floating damage numbers are? I'm currently creating a widget with an animation on, which then updates it's location on tick so it looks smooth. Just wondering if there's a better way of doing this performance wise? As it can start to affect performance when my game gets quite hectic. Thanks

[mental trellis]

There's a plugin on the marketplace that gives you access to all the sort by predicate and stuff.

[crystal epoch]

Sad to hear it 😦 I'll try to do so, thanks!

[crystal epoch]

I've tried one but does not sort precisely how I need, or at least didn't get it to work properly

[mild basin]

you could potentially make the array that of a blueprint class, which contains say an information table, that you would then need to pull and compare according to the specifics of the way you want things to work.

[elfin inlet]

hey im back at doing some ue stuff after working fullstack web for 2 years, im brainwashed

is this the correct node for moving objects in world space

i inferred that this one is just a shortand for current location = current location + delta loc

[trim matrix]

yep

[trim matrix]

yep 2x

[elfin inlet]

one more 😄

do any of these exec pins trigger like tick

[versed sun]

top Triggered

[trim matrix]

Doesn't that just trigger once

[elfin inlet]

so much changed, i'm basically learning ue from scratch

[trim matrix]

Ongoing should execute stuff as long as the input action is pressed

[elfin inlet]

(so that was why my mac10 was shooting 9000 freedom per second)

[trim matrix]

not really, what was the unreal version you last used?

[elfin inlet]

i used the latest pre 5.0

[elfin inlet]

i tried 5 when it first came out but didnt do a lot

[trim matrix]

uhh don't think so

see what it says once you hover over them

the pins

[elfin inlet]

is this VR specific or the new input system is based on this

[trim matrix]

But I'm not sure (still stuck in UE4, i haven't really played around with the new enhanced input actions sys in ue5)

[versed sun]

i think VR or not, no difference

[elfin inlet]

yes, triggered is on tick

im liking the new stuff so far tho

when are we getting Copilot for blueprints

[trim matrix]

Triggered: The action was triggered. This means that it has completed the evaluation of all trigger requirements. For example, a "Press and Release" trigger is sent when the user releases the key.

lol

the desc are so confusing to me then

[elfin inlet]

i wish i could just type "get forward vector of the hmd camera and add delta location to origin based on facing direction"

now i gotta fiddle with nodes X)

[trim matrix]

c++ is always out there

[elfin inlet]

yes i'll try it soon

last time i used c++ it was terrible DX

my good ol i7 6700 didnt help though

im doing VR stuff for the first time

i've had my headset for like 4 years lol

one of the reasons i got a vive was to do VR stuff in unreal

took me 4 years

but the performance and graphical quality of ue 5.3 is basically nuts

i tried unity for some time, c# is very nice but when you try building a UI or input system, its a nightmare

ue just looks gorgeous out of the box

unity's hdrp is such a hassle

im baffled by this again, lmao

[tame pecan]

join us at unrealsharp (Soon™)

[elfin inlet]

iirc laura dreamed of c# and ue

[tame pecan]

im working on it, packaging and delegates left

[elfin inlet]

im gonna try something crazy

gonna paste BP nodes into chatgpt

wth, it almost worked?

[trim matrix]

You'd be better off just explaing the logic

[elfin inlet]

im just trying to rotate the 2D input vector in a way that it is aligned with camera's forward vector instead of world forward

its trivial but i've been awake for 24+ hours and havent done math in a long time lol

[remote meteor]

RotateVector with camera's Z rotation

[elfin inlet]

yep it worked

with some weird additional steps tho

probably my input axes are wrong

[versed sun]

did you Swizzle them ?

[elfin inlet]

it should work tho

maybe its something with the crazy nested vr pawn

[idle notch]

Hey guys, can someone help me with something?

I have a few characters that are rolling initiative in a turn based game.

How can I arrange them based in their rolled number?

[vestal jolt]

Hey. I want Blueprint compilation fail if some of the data is incorrect. Can I do that?

[lunar sleet]

Why?

[trim matrix]

most likely possible in c++, but not in BPs themselves

hold on, I'll try something stupid tho...

[edgy ingot]

Define "incorrect"

[trim matrix]

I know how to make the engine lag out and then crash with BPs only if it'd be wrong 🙃

[vestal jolt]

I have a c++ class derived from UUserWidget and a blueprint that is derived from it. This is basically a custom Table widget. The Table class has the layout of the table that must be filled. But there may be some inconsistencies like forgetting to set the CoulmnType. I want every time I use this Table and forget to set the column type for compilation to fail

[lunar sleet]

Something that can prly be done with #cpp , doubt you can achieve that within bp, whether you should be doing it this way is another story

[edgy ingot]

Dont understand this compilation error wishlist thingy. All you have to do is just check the value of column type?

Sounds like a simple check to me why are u overcomplicating stuff

[trim matrix]

I'd just add a screaming debug print on constructor

[trim matrix]

are those two bools the exact same one?

[tame pecan]

yes

[untold cave]

I have a problem, I launch my project but I can’t play with my character, can someone help me please😭 🙏

[edgy ingot]

Check your game mode

Add player start

[untold cave]

okok thanks you

[vestal jolt]

Found the solution. The UWidget::ValidateCompiledDefaults does what I need

[stray halo]

some one im begging im trying to shut all lights off with a array of light actors but when it goes through anything to do with time its only using one actor

[lunar sleet]

Wdym “anything to do with time”? Are you using delays in a for each loop?

[stray halo]

so like when i used timers it would work but if i hook a RandomFloatInRange to the time on it, it would choose different numbers in the range to turn off each individual light, same with delays

[lunar sleet]

Show code. Also for each loops by default are meant to run in one tick, so introducing latent actions such as delays will instantly break them

[stray halo]

i was just about to run this string not sure if it works yet but its what i have set up now

turn off power is ticked on right side now just noticed them if you were wondering yourself

[edgy ingot]

U r not even looping

Also i dont understand what it is u r trying to do

Just bare in mind that loop happend in one single frame

[stray halo]

when the power is back on i want it to run a randomized time to turn it back off

[faint pasture]

For all lights or per light?

[stray halo]

all lights

[trim matrix]

How do you want it to turn off? Like how should the delays happen and stuff

[stray halo]

this is how it currently shuts down

well right now i just have test times set up to it but i want it to take a range of 45 secs after to 1min 30

[faint pasture]

Describe what you want to have actually happen. You press a button, and then what happens in the world, and then what happens after that?

[trim matrix]

@stray halo correctly

[stray halo]

Press power switch, turn on lights, then when lights are back on have a delay for the lights to turn back off in a set range of time so it doesnt happen right after the lights are back on with the range also being random

i want all lights to turn off together, i managed to get all lights to turn on together but because i set power off up to timers and ranges it scatters the lights turning off at different times

[lunar sleet]

@faint pasture Are you excited about #game-math ? 😀

[faint pasture]

Press switch -> for each light, turn it on
Done -> delay (random time) -> for each light, turn off

To reiterate, press the switch, turn all the lights on, delay for a random amount of time, turn on the lights off.

[stray halo]

sorry if this may sound stupid but how would i go about getting all lights if they are in an array

i did what you just said but i have an issue with it picking only one light out of the array and turning it off

[thin panther]

Then you aren't looping through it

[thin panther]

The for each is a critical part of that

[stray halo]

that seems to have fixed it so far

[ebon olive]

Does anyone know the difference between select node and branch node? like when is the best time to use either of those if they both works similar 🤔

[stray halo]

Thank you all so much bro ive been going through so much just to do it on my own but i didn't think i could make something so simple that complicated i appreciate all the help

[compact vapor]

will event begin play fire off in an actor if I spawn the actor in a level?

[edgy ingot]

They serve completly different purpose, not even compareable

[edgy ingot]

Ofc

[compact vapor]

even at runtime?

[edgy ingot]

Only at run time

It doesnt fire in editor time

[compact vapor]

yea, I guess that was kinda a stupid ass question lol

[edgy ingot]

No question is stupid, just ask what u dont know

[compact vapor]

are there specific uses where a data table should be used over a struct?
trying to understand both a little better

[edgy ingot]

They are not the same thing.

You use data table normally to read static data

Like a libary of anim montages for example

Or item infos

[compact vapor]

what If you needed an index of each item (a name / description / icon for UI)

would this be for a struct?

[edgy ingot]

Your data table will require a struct

Make the struct FItemInfo.

It can contain , name , desc, icon.
Create a data table and use FItemInfo.

You can then start adding item infos in the data table

[compact vapor]

so if the player picked up a weapon and I need to see what weapon that was and what data was associated with it, would I just look it up in the data table at runtim to see if an (id for instance) mtaches?

what if 2 guns are instances of the same class but have different amounts of ammo left?
would this invole storing an instance of the struct in the data table?

[edgy ingot]

I would setup weapons and items more coherent than that. But im not good at explaining. Maybe others can help.

But in a case of weapon and items, i will use both data table and classes.

Each weapon can look up its default value on weapon data table, but it would also have a class that defines the weapon.

So the damage of the weapon can be read and write beyond what the data table offers

I dont know what you mean by storing an instance of struct in data table. Data table is read only entity (at least in bp) and i see it as static object .

Dont see what instancing got to do in this context

[compact vapor]

i understand, although I guess an instance of a struct would have to be stored to some degree to store item specific instanced data for inventories/
(how else is the Minecraft sword supposed to display half durability once you pick it up?)

I guess I'm thinking of this in terms of an inventory.

If you had an inventory object that stored each item the character had, would you use a struct to hold each instance of the item?

[edgy ingot]

My inventory would be an array of item struct

[compact vapor]

I had an idea a while back that my inventory would be a map of int's pointing towards items

0 > item instance
1 > item instance
ect ect

and then you would have a "none" item type that way you could handle blank inventory spaces.
doing it this way would be i guess a type of array but gives you the flexibility of using indexing because the map contains that functionality.

does this implementation have big flaws?
it seems like the right way to go about it.

[edgy ingot]

I have no idea what you mean sorry. What is number greater than item instance even mean

[compact vapor]

?
where did i type that, can you be more specific?

[edgy ingot]

0 > item instance

Oh you mean pairing index with item instance using map

[compact vapor]

yes

the map starts with its first index (imagine only one thing in the map)
the key is an int ( 0 )

value is BP class i guess

[edgy ingot]

I dont use map for inventory so i dont know. Doesnt seems like the right approach

Normally just struct with guid and other infos

I took inspiritation mostly on dynamic combat system from market place

[compact vapor]

actually, with a array, you could just remove an element and it would auto adjust.
so dropping an item out of your inventory would almost adjust sutomatically.

with a map, you would need to loop through the entire thing to re assign each element to one less index.

I didnt think of this, arrays might actually be the only way to go...

[edgy ingot]

Weapon and inventory system can be a daunting task. When not done right , life is a little hard.

Im still learning my self and i dont think i could come up with better method than others. Hence why i look into other projects to see how things r done

[compact vapor]

same thats exactly what im doing, im using a community template

[edgy ingot]

If u dived with guts alone, chances are u might end up redoing the system

Thats just my opinion but i can vouch thst for most of us. We always end up redoing our system everytime on new project because we discovered better ways to do stuff

[edgy ingot]

K as long its not youtube tutorials

[compact vapor]

lol what else you got for references? lol
i got nothin

[edgy ingot]

I would say look at epics or some credible project

I used dynamic combat system and still stuck with it atm. Working on new multiplayer project tho, and i will have to figure out my inventory system too eventually

[compact vapor]

Well I'll definitely think more about this.
Perhaps we could get a larger discussion going in the discord server? about different data types and their advantages / disadvantages with creating an inventory systems.

all are welcome to contribute!

it seems to me, by my estimation,

Maps are the go-to if you need built in advanced indexing (and will absolutely acell at blank inventory spaces and / or inventories where some indexes are more important than others, especially in a UI)
Arrays are the go-to for when specific indexes are not any more important than other indexes, (and arrays are god tier at sorting and auto adjusting size)

[edgy ingot]

I dont agree with whats written but if u need real answer, maybe ask in #cpp . The people there have brains

[trim matrix]

why is it still white?

[edgy ingot]

The material used is not the same

[trim matrix]

thx

[tidal marlin]

Hello. Faced with the problem that the player pavn without a player controller is destroyed after a some time. Please tell me, is this a problem of the engine or my code?

[dawn gazelle]

It's part of the player controller's code in APlayerController::Destroyed() as it calls APlayerController::PawnLeavingGame() which destroys the pawn.

[elder lodge]

Is GameMode's beginplay guaranteed to fire before everything else? Is that where I should instantiate my manager classes or in GameInstance?

[remote meteor]

depends on the scope of the manager classes
GameMode begin play fire on each level opening
GameInstance initialize fires once on the game startup

[elder lodge]

I have a Manager class that runs the gravity on the level; gravity objects sign themselves in with the manager class in an array when created and when destroyed. It also has some gravity constants and logic.

I'm getting some race conditions where some actors at the beginning load before the gravity manager is properly loaded, so I'm trying to figure out how to best arrange this without just using a bunch of delays. Event Dispatchers?

[faint pasture]

What is the manager, just an actor?

[tidal marlin]

No, it turned out that the engine considers the Character irrelevant when the motion component is disabled, physics is disabled and visibility is disabled, after which it removes it from the Client side.

Fixed Always Relevant.

[elder lodge]

Yep, just an actor that holds an array, a constant, and Event tick logic to propagate the gravity forces.

[tidal marlin]

Thank you

[faint pasture]

Is it spawned at runtime or exist on the map?

[elder lodge]

I had it existing on the map and on its BeginPlay, it assigned itself to the GameMode's GravityManager variable so that from the GravityEntities they could ref GameMode > GravityManager.

[faint pasture]

Why is it not just a component on GameMode?

[elder lodge]

Because that idea didn't occur to me 😂

[remote meteor]

i suppose if they dont need transforms they could just be an UActorComponent on the AGameMode

so they would initialize together with the gamemode

[elder lodge]

The abstraction of components and GameMode, for some reason I didn't consider that.

[faint pasture]

The correct approach is probably a subsystem but a component on GameMode or GameState is good for the BP version

[elder lodge]

It's a good idea. I had been trying to figure out how to expose the GameMode's variables such that I could assign the GravityManager from the editor, but that makes sense as what I was trying to do.

[remote meteor]

depending if such system needs to stay after doing a level change, if no need to change, then it should be a subsystem

[faint pasture]

your race condition is probably between the manager registering with gamemode and the other actors looking for it, they all fire on begin play so who knows which is first

I'd go with a component tho

GameState if it's meant to be multiplayer

[elder lodge]

Such a simple solution, thanks.

[surreal juniper]

probably a dumb question but right now im finding the right speed for the player based off of a bunch of booleans

surely theres a better way to detect if the player is sprinting and moving forward

or like moving backwards

anyone have any good ideas

like, i really dont wanna have to do this for prone and crouch too

[serene condor]

How do I change the colour of a Text block in the Blueprint of a UI widget. Like what do I add to the ‘In Color and Opacity’

[grim sand]

Right click it, and it should allow you to break it, which allows you to set a colour

[grim sand]

Alternatively you can drag out from it and type "Make Color" like so:

[serene condor]

I have make slate color.

Doesn’t give me the option of make color

[grim sand]

Don't worry, dumb questions don't exist. I assume sprinting is a user based action right? They press a button and then the characters starts sprinting?

[grim sand]

Which type of BP are you in?

[serene condor]

User widget

Target is a Text Block

[grim sand]

Ah check, that makes the difference. Then slate colour is indeed what you want 🙂

[serene condor]

Yup. It works

Thanks

[grim sand]

Does anyone know if function local variables can be seen in the blueprint debugger?

[surreal juniper]

aye, so i have a couple states. sprint, crouch and prone. When sprinting, if the player is moving forward theyll go faster than moving sideways

[trim matrix]

how can i create a macro that works like this?

[frigid narwhal]

Anyone know how I can lerp transform between skeletal meshes?
So I am tring to blend out of physics control in a hit reaction. Someone suggested to use 3 bodies, 1 for physic simulation, 1 for kinematic and 1 that is not hidden that will lerp between the other bodies. Anyone know hot to do that?

[grim sand]

Gotcha. So you probably would want to check on a timer (set to 0.1 or something), the forward and right vector of the player. Based on the value coming out of it, we know if we are going forward/backward and left/right in your context.

Then based on that you set 2 booleans: bMovingForward and bMovingRight. You set these based on the result of the timer.

Then I would make a generic "UpdateMaxWalkSpeed" event, that I can call for the sprint, crouch, and prone, and based on the earlier set bools, you can now set the max walk speed.

You could switch on an enum for the different states you have to make it a little cleaner on the last step 🙂

[surreal juniper]

hmm thats basically what im doing for the stuff except enum

damn was hoping for a cleaner way

[idle notch]

Hey gues, quick question.

If I use the insert (array) node to insert something in an index that already has something else in it, what happens to the original object?

[grim sand]

I mean, alternatively, you can just disable the sprinting when the user is moving in any direction other than forward. That would cut back the bloat

[surreal juniper]

yea but i wanted like different speeds for side walking, forward and side movement and so on

im thinking im just going to have to do the tree thing :(

[grim sand]

Right, then yea I think this is the way to go. I would highly recommend making a generic update event to make sure you don't copy the same code 3 times

[surreal juniper]

aye ill do that then

thank you!

[grim sand]

This would be how I would do it.

[trim matrix]

thanks man

[outer garden]

So I have this set up for trying to get one widget to bring up anohter. This is meant to trigger a text to come up when the button is clicked in the first, but the button clicks are doing nothing. I'm using the widget switcher. I'm definietly missing something, I just dont know what.

[edgy ingot]

Thats not how you use widget switchrr

U r just creating a new widget

There are tutorials covering how to use it

Look at matthews video

[outer garden]

I've created a a pause and start menu already, fwiw.

Mathew is...who? idk who mathew is

[edgy ingot]

Nothing to do with how to use widget switcher

[hasty sable]

Should you put input actions in the player controller or character actor?

[edgy ingot]

Type widget switcher unreal in google. it will be the first video

[lunar sleet]

Depends

If it’s a character driven gameplay, most of them can prly live in the character

[crisp urchin]

Anyone experienced with invalidation boxes (?

[lunar sleet]

For some things, like making an RTS, playeCon might be better

[edgy ingot]

Whats that?

[outer garden]

Okay, so it turns out i dont have a widget switcher, thought i did

but either way, i think the issue lies in that the second widget isn't getting called somwwehere

and i dont know why

[edgy ingot]

You should follow some basic tutorials. Right now u are assuming a lot of things

[outer garden]

I have been following them.

Like i said, I made two others sucessfully

[edgy ingot]

Anyway if u want to create widget, and want to display it. You need to add it to viewport

Creating them will not display the widget out of the box

[outer garden]

okay, adding to viewport, that makes sense yeah

[floral patrol]

Trying to get my vehicle to make my ai character ragdoll/ get damaged after being hit. Any ideas how I'm doing this wrong? I set this up in the vehicle bp, cast to the child ai bp

[grim sand]

Does the zombie enable physics? What is the actual issue you are running into?

[floral patrol]

The car just runs into him and the zombie doesn't do anything. Kind of like I bumped into a building

[edgy ingot]

Print string or add breakpoint to see if the simulate physic code is run

[grim sand]

Ah because you are not simulating physics on the skeletal mesh. You are doing it to the capsule component instead

[floral patrol]

Like this?

[edgy ingot]

Also orint string at the top after simulate physich

U shouldnt need to simulate physich on thr capsule

Just the skeletal medh

Also check if you have an actual physich assets on the skeletal mesh

[floral patrol]

What do you mean by this?

[edgy ingot]

Its literar

Drop a print string after the simulate physich node

If it never get called then ur simulate physic node never ran

[edgy ingot]

Ye and i will suggest to look for resource on how to debug your game

[floral patrol]

Will do, I've been trying to find any forums/ youtube videos regarding any of this but haven't had much luck.

[outer garden]

remove from parent is apparently what i was looking for lol

but now i gotta figure out how to only get one text box and not all of the text boxes from the other one in response

[edgy ingot]

What a mess

[outer garden]

Wow.

Thanks for the kind critisim.

[grim sand]

Alright this is definitely not how you would want to do this 😅

[outer garden]

i just want to make it work :( darn it

[lunar sleet]

I believe there are dialogue plugins you can get btw

[serene condor]

How can you communicate between a UI widget and the Player. I tried adding a custom event in the player blueprint and tired to get message in UI. But it wouldn’t show up and when I turned off context sensitive and found the Custom event message node. I could get the reference to the player character and the message working. I tried Blueprint interface. And that didn’t work. Is there any other way?

[outer garden]

at this point im just trying to get it to let me didsplay something from a clicked button that isnt a second button

[edgy ingot]

With how things are setup from your end. You will end up scraping the whole thing anyway

[outer garden]

Dude, if you have nothing kind to say, then just don't...

[edgy ingot]

Im not being mean or kind

[sly vine]

Hello!
I have made a WorldSubsystem blueprint which has an intermediate cpp parent that will only register the subsystem if it has IsInBlueprint = true (ShouldCreateSubsystem override).
It works pretty good except that to get it to be registred I have to open the blueprint (then the ShouldCreateSubsystem is called for it). If i don't do that the GetSubsystem will be null.
Any idea how I can have it auto register so I dont have to open the blueprint everytime I restart my project?

[outer garden]

I appreciate critisim and people's responses when they're meant to help and not be a jerk but...
Really? That's not negative at all to you?

[edgy ingot]

I just say my honest opinion

Where am i being a jerk?

[lunar sleet]

Btw for widget related stuff, you should ask in #umg

[grim sand]

I would highly recommend following some kind of tutorial on widget switchers. Widget switchers are meant to switch between widgets that already exist, generally speaking.

But if I assume what your context is (displaying responses from shops/shopkeepers) you just want to have one dialogue widget, that gets created and hidden at the start of the game. Then once the player interacts with the shops, the widget gets set to visible, and you change the text (through a text variable), to show different responses 🙂

[edgy ingot]

Dont even understand why u feel attacked

[lunar sleet]

May need to expand on what you’re trying to achieve

[outer garden]

that makes a lot more sense than what im going for yeah, i had kinda just based this off the start menu and it seemed to be going okay

[lunar sleet]

Prly best to let that one go

[outer garden]

I'll ask there from her on

[dark drum]

I made this a few months ago if your wanting a dialogue system. A lot of people said it really helped them understand a lot of concepts. It might get you going.

https://youtu.be/88xikHeYQDA?si=5160QKEsLRytBGif

[floral patrol]

Hmm no print string popped up.

[outer garden]

i think i saw this earlier yeah

[edgy ingot]

Then work from there i guess. Make sure ur hit event actually triggered

[outer garden]

And "it sucks so bad you're probably gonna need to toss it!" is like. disctintly not positive. Honesty can actually be mean, i've been in that camp before and learned how to tone it back. That's all i'll say on it, i'll probbaly take a break rn cause ive been working on this for a couple horus and probably could benefit from it lol

I'm gonna take a look at the other options ya'll mentioned tho

[lunar sleet]

Dialogue systems are not easy afaik

Hence the plugins out there

[outer garden]

the irony is i can code this in c++ easily and im good at that side, but this side of things im struggling hard

regular c++, not with unreal lol

[lunar sleet]

It’s def an adjustment

But #cpp can help in that regard

[outer garden]

True! I've scrolled through there a couple times.

[carmine palm]

So opening inventory UI and setting it to input mode ui only, but then I obviously cant use i to close it again. Any ideas on what I could do? Need no char movement/input but want to be able to use same button to close inventory lol

[edgy ingot]

Have some input in the UI

You can use listen for input action or
Override on key pressed

[carmine palm]

listen event in the widget graph?

[edgy ingot]

There is a node in widget graph called listen for input action

You can bind the key to some event

Eg calling your char to close inventory

[keen girder]

why are items (an index) being added to the struct? i am just taking an item and changing a single value. what am i missing here?

[edgy ingot]

Are u gonna use set member or set array element? Chose one

[keen girder]

oh boy... 🤦‍♂️

yeah thanks for taking your time

[edgy ingot]

Thats not the answer to your problem

I mean w.e bug u have

[keen girder]

ah no... it is still happening

[edgy ingot]

What do u actually want to do?

[keen girder]

just saw it... so i just want to add the mesh instance to eachh existing struct but i keep adding a new ones

[trim matrix]

this will get always the center of the game in any monitor right?

[keen girder]

struct loop > get every item and at a mesh instance to the existing item

[edgy ingot]

Where is this bp? Is this for run time or editor utility widget stuff?

[keen girder]

this bp is a level actor which is called by an editor utility widget

[edgy ingot]

K i cant comment on editor stuff

Not sure how its serialized

How do you actually populate the array?

Might want to clear it first before adding

[keen girder]

EUW part is running fine as the struct is being created and fed with its initial data correctly. the screenshot above is from the level actor BP which should just add data to its own struct

[edgy ingot]

Show how you populate the array

[keen girder]

EUW sends data to actor BP... only new items are being added and its running fine... just the screenshot above is adding items

[edgy ingot]

The screen shoot above shouldnt add any items

As far as i can tell

I could be wrong but nothing indicate adding an element into an array in that function

Hence my suspicion with how the array is populated

[edgy ingot]

I think just try to clear level editor mesh right before the loop

Other than that i have no idea

[keen girder]

EUW is not able to create duplicates this way. only if i set members/set array element

ok i ll give it a try

[edgy ingot]

Set member doesnt add element to your array

An array element gets added either by the add node or set array element with size to fit box ticked

[keen girder]

yes i know, ive done it this way before... but as soon as i connect "set member" i am getting dupplicates

[edgy ingot]

Unconnect and see what happend

And by duplicates u mean ur leveleditor array size increases?

[keen girder]

exactly

[glossy cloak]

Without using a spring arm, how can I create an offset for a widget component to float over my character's head? It just snaps to local 0

[carmine palm]

How do I make sure the input is "I"

i key*

[edgy ingot]

Have you tried clearing the array? Before the loop

[glossy cloak]

Do you just want to run a function when the I key is pressed?

[grim sand]

You could attach it to a scene point

[carmine palm]

Its for when my inventory is open, player loses game input and gets mouse input only. (Besides specific ui commands like i to close inventory)

[edgy ingot]

Go to proj setting, input. And add an input actuon mapping

[carmine palm]

I have my IA map

[edgy ingot]

Name it something and assign a key

[carmine palm]

My I key currently opens inventory

[edgy ingot]

Just make the key the same as your IA map

Ok so use I then

[glossy cloak]

Ugh. I tried that, but I was using an existing scene component in the blueprint that might have been being moved to 000 for some reason? I added a new one and it's working fine... Thanks. lol

[carmine palm]

wait so make another input?

Another input action map

[edgy ingot]

If you go with listen for input action route u are using old input system

[carmine palm]

oh

so that will trigger my I button on player?

that I have?

[edgy ingot]

On your widget

[glossy cloak]

If you just type "Inventory" or whatever you named the control mapping it should give you an input action event.

[edgy ingot]

Not your player

[glossy cloak]

Oh, this is on a widget?

[carmine palm]

yes

[edgy ingot]

If u want ur player to trigger then u need to set game and ui for input

Instead UI only

[glossy cloak]

There's a couple ways to do this on a widget.

1. On your player or player controller where the inventory button is pressed, grab your widget reference, check if it's valid. If so, call a "close" function, if it's not valid, create it to open your inventory.

2. On your player when the inventory button is pressed do a dispatch call. On your widget, on event construct, grab a player char reference and bind an event to that dispatcher so the widget can run logic on the button press

[glossy cloak]

Yeah. And this.

[lime basin]

i have set up input bool value via code but im getting this error when im trying to read that value of isAiming no idea why its failing

[grim sand]

Whatever the target variable is, it does not exist when you try to read something out of it

[grim sand]

If you right click it, at the bottom of the context menu you can click "Validated get" which will help to avoid the error. However, your real problem is why the target variable is nothing at the time when you try to access it

[lime basin]

yea idk why is setting name of my project as target variable it supposed to be player no

[edgy ingot]

Thats not the right place to set target and char too

[lime basin]

im just testing i know

its a dirty prototype

[edgy ingot]

Do tell me where you should set it

[faint pasture]

your ref setting code here is doing nothing

[edgy ingot]

Cuz i dont see why u want to set it every frame, prototype or not

[lime basin]

im not here to argue or anything just trying to learn

[edgy ingot]

Im not arguing either

[faint pasture]

Frame -> is stored ref valid? -> yes -> proceed
-> no -> try get it -> set it -> proceed

getting pawn owner and casting every frame won't kill you right now tho, that's fine for prototyping

[edgy ingot]

Im telling u how to overcome your error

Because they should be set at the start

[lime basin]

i just to get it to work then i will set up a start of scene

im weird like that

in Initialize animation

[lime basin]

i want my player just to play animation when bool is true

[edgy ingot]

You need to set target

U havent show us where you set "target"

[lime basin]

thats the only part of BP where target is mentioned

[edgy ingot]

Well if its never set , then thats the problem

Target didnt point at any object in the world

[lime basin]

I was hoping that my casting to BP_ player would do that :/

[edgy ingot]

Casting is just a type check

[lime basin]

men i suck with blueprints

[edgy ingot]

U need to actually tell target, which object in the world it is suppose to point to

[lime basin]

i see and i will just have to google that to see what i can use

thanks

[edgy ingot]

U mentioned baiming?

Thats probably what a player character or pawn would use

[lime basin]

so isAiming? is controlling animation transition and isAiming is reading input value

[edgy ingot]

Anim instance job is just to read values from its owner

And reflect the value to formulate which animation it should be playing

So right now, your bp character have a variable called isAiming?

[blissful dome]

Hey! If anyone can help with a quick hiccup I’m having that would be great

[lime basin]

yes my Animationblueprint has variable isAiming? and my Blueprint of character has a bool value in code called isAiming (thats input action value )

[edgy ingot]

Ok so u just need to set ref to your character

On anim init. Try get pawn owner. Cast to your bp character then promote that as variable

[lime basin]

im using starter 3rd person player so its already set up

[edgy ingot]

Do that and i will guide u to the next step

Yeah just show the part where you set the character ref in anim bp

[lime basin]

i did promote as variable in the photo i showed

[edgy ingot]

@lime basin u didnt connect it

Fix it and show new screen shoot

[brazen pulsar]

So, I have a system where the date changes, and I'm hoping I can make changes to the actors for different days. I figure it'd be easier than duplicating each level and switching them out depending on the date. Trouble is that while I can change the date, the sleep function isn't updating the actor. I think it's just b/c I don't have the sleep function connected to anything, not sure what I should do.
Basically, the sleep function should work like a refresh button

[edgy ingot]

See the pins of the promoted variable? It is left unconnected

[lime basin]

ohh one sec

[dawn gazelle]

Your first image is calling an interface called "Sleep". You need to pass in a reference to the thing that you actually want to call sleep on.

Right now, it's calling it on "Self"

[edgy ingot]

Add a new pin on the sequence node

[brazen pulsar]

Yeah, what do I reference? Cause 'sleep' is just a function built to refresh everything after the player sleeps

[lime basin]

Okay

[edgy ingot]

There on empty space you want to get bp third person char. Then from the blue pin drag snd type IsAiming

[lime basin]

okay then to connect isAiming and SET isAiming? to animationBP

I need better names 🤣

[edgy ingot]

Yeah you basically get the reference of the character, get the value of is aiming from the char and set it to isaiming jnside the anim bp

[lime basin]

like this

[edgy ingot]

Yup

[dawn gazelle]

If you wanted to call it on an instance of a "milktoast1" actor, you'd need to feed in a reference to that specific "milktoast1" actor. If you want to call it on many actors, you need a reference to all the actors that implement it and feed them in to the target.

[lime basin]

yay no more errors but it wont transition in animation

i will figure that one out thanks men

in unity its so much easier for me to set animatiosn via just code

🤣

[edgy ingot]

Show me the transition rule if u want

[brazen pulsar]

I think I understand

like a reference to all Actor class

[dawn gazelle]

What you probably actually want is an Event Dispatcher. You can create that in your game instance, and call that dispatcher when you want things to sleep.
On begin play of actors that you want to listen to it, you'd get your game instance, cast to your custom game instance, and bind to the event dispatcher.

[keen girder]

i ve put the function 1:1 into construction scrip and it is running fine

[edgy ingot]

The circles between idle and aimstate. Double click the circle on the left to get in then screen shoot

[brazen pulsar]

Completely lost

[lime basin]

the one on left

when bool is false to return to idle

[brazen pulsar]

how do I event dispatcher?

[edgy ingot]

Dont think it work the same way. Im just not sure how euw is serialised, have u actually clear the array before the loop?

[edgy ingot]

And the one on the right?

[keen girder]

i am not sure if clearing is an option as i may want to keep "old" SM in the array

[edgy ingot]

U r potentially creating duplicate if the data presist. But if u dont want to try then i dont know what else i can say. Thats prob the first thing that come into my mind when i looked into your function

[edgy ingot]

Show pic of the update anim again. Make the picture a little bigger

Then also show how you changed isaiming on bp third person char

[edgy ingot]

Looks allright. And i take it aim state already playing some aiming anim?

If thats already checked. All thats left is to check if isAiming actually altered in tps character

[keen girder]

its running fine in construction script and not creating doubles as it should. clearing the array before dropping initial data is avoiding duplicates as well

thanks for taking your time

[brazen pulsar]

ohhhh

[lime basin]

xmm im not sure what you mean by tps character

[edgy ingot]

Third person character bp

[lime basin]

ohhh

[lime basin]

nah bp is alright i set up in as hold and release i think thats the issue

in input action

[edgy ingot]

Show

[edgy ingot]

I think just remove that

The hold and release bit

[lime basin]

and replace it with what

[edgy ingot]

Nothing

[brazen pulsar]

I think I miscommunicated. I'm not looking for a system that makes all the npcs sleep at once or anything, I'm just looking for something that can change their positions based on the date. Like, the player hits the bed, wakes up the next day, and milktoast isn't in the scene, that kinda thing.
Does this work for that?

[edgy ingot]

Dont need modifiers

[brazen pulsar]

oh, or suddenly it's raining

[lime basin]

haha it needs it that constantly changes state it looks funny

[edgy ingot]

You can set is aiming to true and false using started and completed

[dawn gazelle]

Event dispatchers are a means of communicating from one thing to many. You are "listening" for that event to be called in an actor that wants to care about that event.

[brazen pulsar]

oh, ok, perfect then!

[lime basin]

yea i did

[edgy ingot]

Have u tested the value?

Print string isAiming on tick in third person char

Or addonscreendebug messages in the binded function if you want to print from cpp side

[lime basin]

yea i did but i will fix this myself

thank you SO MUCH MEN

i learned something from you today

i will fix this on my own

[edgy ingot]

Good luck ser

Im off to bed

[lime basin]

thank you bro good night

[edgy ingot]

I think ur almost there

[lime basin]

yep yep 🙂

[autumn crane]

My brain is exploding. Any idea how to Cast To a static mesh actor.. say the wall in the default 3rd person map named SM_Cube6. So when I interact with an object, I can change something about the wall. I know how to do it via a blueprint, but I dont want every single object in my map to be a blueprint for this specific change

[edgy ingot]

Get a ref to the actor when you interact

Then cast away

Example, press E to line trace. Get hit actor, cast to static mesh, fo something

[autumn crane]

Thats what I am trying to get to. I haven't had any problems finding blue prints, but how do I get to where I can choose a specific static mesh actor that is currently in the world. Like a wall for example

[edgy ingot]

I just describe how

You can line trace

The hit actor will be w.e u hit

It can be a floor, wall or door

Everything u place in the level is an actor

[autumn crane]

Hmm.. Maybe I am just not understanding. i'll keep at it. The actor I am "hitting" is not the target I am trying to change. I am hitting the object fine, it is just not doing what I want because I am not sure how to get the reference of particular static objects in my scene

[edgy ingot]

Then do the change when u hit the actor u want to target

[lime basin]

@edgy ingot this was solution lool

[edgy ingot]

Get hit actor, cast to static mesh actor. If static mesb == wall then change material

Or you can check with tags

U define the rule

[autumn crane]

Oooo tags. That might work best lemme play with that

[edgy ingot]

Eg. Get hit actor . Actor has tag "specialwall", set material 0 to red

[autumn crane]

Got it with the tags. Holy cow. Lol Im such a noob. Thanks

[elder lodge]

if hitting the wall is supposed to change a different actor, might be worth investigating event dispatches too if that's going to happen a lot.
Or you can expose variables on the wall such that the wall contains logic for sending something to a specified target
a few ways to skin the cat depending on your ultimate goals

[carmine palm]

Man

I cant get this to work how I want

restrict to ui movement but be able to accept specific keys lol

[zealous moth]

so this is my tiles struct to determine by index what tile it is...

I am starting to think there is a better way

parse string?

[thin panther]

rip for that bp struct

[carmine palm]

Figured it out

Mind taking a gander cuppa?

[thin panther]

shoot, no guarantees i'll be any use

ui is not my style at all

[loud timber]

hi there - how would i go about geting one object to rotate around another object like this using a joystick?

[elder lodge]

there is a rotational movement component

With an offset available

[loud timber]

sorry i meant to add with a joystick

[elder lodge]

have the input from the joystick map to certain rotations of the object; I think there is an offset available somewhere in the transforms

[elder lodge]

lol what do you need to do with these?
Why can't you just have the tile have a function or a variable for what type it is, and to return that?

[loud timber]

would that blueprint need to be a character?

[elder lodge]

not need to no

[loud timber]

would it need to be a pawn?

[elder lodge]

don't think so

i have'nt dealt with movement applying outside of the character much but i'm assuming hyou can always map things to raw input

[loud timber]

i tried just getting inputs to an actor blueprint and at runtime unreal defaults to creating a player character

[elder lodge]

huh. idk!

[loud timber]

all good thanks anyways

[carmine palm]

Whats the uh

[solemn basin]

Can anyone help me understand Blueprint interfaces? I want to sent information from a widget (Hand) to another widget (InfoPanel). But idk how to set the target for the Call of the BPI.

[carmine palm]

BP paste sight?

[dawn gazelle]

Interfaces are generic functions that you can choose to implement in a variety of classes and each can respond to that function call in their own way. In order to call the interface on an object, you need a reference to the object you're wanting to call the interface on. If you're only ever implementing the interface in a single class or hierarchy, then an interface is probably not the tool to use.

[sonic crest]

[Deleted post out of embarrassment]
need to get my eyes checked

[carmine palm]

oh man

This website made it ugly

lol

woops

https://blueprintue.com/blueprint/m9fr6z0j/

Widget

https://blueprintue.com/blueprint/53co0n3k/

Just want to see if theres anything I should do to make it cleaner. IE un-necessary nodes/casts

[solemn basin]

It'll be used elsewhere but i'm just learning how to impliment BPI.

[thin panther]

first off that player controller cast is unnecessary there

[carmine palm]

Well its going from controller->playerController

object

unless there is a getPlayerController

[dawn gazelle]

Ok, so you need a reference to the widget you're wanting to call that implements that interface. There is no "easy" way of doing that if there's no good relationship between one widget and another.
One potential way is to use Get Widgets By Class, but that then would only work well if there's only one copy of that widget class currently existing.
Another way is if there is some kind of logical hierarchy to the widgets, like if the one widget is a child to the other in some way, then you could potentially get a reference through getting parent/child widgets.

Otherwise if they're completely unrelated and there's multiple of them existing, you need some better way of signaling something to the other widget, and an interface isn't well suited for what you're doing. An event dispatcher is likely better as you could create it in say, your HUD class, and call it from one, and bind to it in the other.

[zealous moth]

@elder lodge if int appear for that particular row struct array, replace default tile with that

I think I will use a string parser

[thin panther]

oh yep, you're absolutely right, missed that :P

[solemn basin]

thanks for the response, I'll have to look into each of those because i'm not sure how to do any of that.

[carmine palm]

nerd

😛

getPlayerController does it by ID, so as long as I keep it single player it would be fine

But the way I have it keeps it on whatever player object its on

[zealous moth]

@thin panther is the srruct that bad?

Otherwise I would do like A11A12T13

And parse it

Probably regex

[thin panther]

bp structs are always bad

prone to breaking a lot

[zealous moth]

Yeah.... afraid of that

[carmine palm]

^

They literally just got me to make cpp structs

[elder lodge]

I mean that sounds even worse for scalability

[thin panther]

Is this for an item id system?

[zealous moth]

a tiling system. I have a 0 to 90 indexed tile room, i want to assign it a specific pattern.
the default is an empty ground tile
by using a string code, i could make X tiles be this or that.

[floral patrol]

Getting this error when I drive my car into my zombie character, I've tried putting "is valid" on everything but it's still not working. Also here are my collision settings for the character idk if these are right or not. It does make the zombie character rag doll though when I hit it with a vehicle. I have to set the skeletal mesh to ignore/overlap vehicle or else it starts freezing up the game if I keep it on blocked. Any help or suggestions would be awesome.

[zealous moth]

I guess I could serialize it as an string like so:
[A:1,2,3];[B:4,5,6]

[thin panther]

You could also try your luck serializing it into something like a JSON object

[dawn gazelle]

You probably don't want to destroy the capsule component in the event hit. There's a lot of things that are looking to read from it until the actor is destroyed.

Quick question:

How can I add zoom feature

[versed sun]

do you use a springarm?

[carmine palm]

Si senor

[versed sun]

Set Target Arm Length

on the spring arm

the smaller the number , the closer it is

[carmine palm]

Would that have to be a new IA then?

Since my look is x-y based

[versed sun]

for Zoom? yes a float

[carmine palm]

ah float okay

[versed sun]

usually like mouse wheel up and down

here is my favorite method

supper smooth , and locks into zoom steps, so that you can count your clicks and you will be where you want

[carmine palm]

oh man

thats long lmao

[versed sun]

thats.... small

[carmine palm]

How do you grab arm length

from the ref

oh weird

I see it now

Wasnt showing up

[versed sun]

Spring Arm, bottom Left in graph

Effect is this
https://app.screencast.com/z6NdzTB9Zc2AA

make it once , and copy/paste it between projects

ill make a link

https://blueprintue.com/blueprint/s4ikoepc/

[carmine palm]

So my Timeline doesnt have an alpha node

Am I missing something?

[versed sun]

dbl click the timeline node

the colored title part

[carmine palm]

yea did that

Havent used timelines yet lol

[versed sun]

they are fun and handy

just a simple 0 to 1

[carmine palm]

interesting

this looks fun also

[solemn basin]

What is the best way to send the CardInfo to the InfoPanel whenever I Hover over a card?

all I can do right now is print the name of the card.

[carmine palm]

@versed sun what is spring clamp x/y node?

[versed sun]

a Vector 2d , and Split pins

[carmine palm]

Did you just do a set before that?

Or where did you get it

[versed sun]

just the default values 100-250000

[versed sun]

that works too

[carmine palm]

ah its backwards

lol

Know how I would flip it?

up is backwards down is inwards atm

and want to limit it to a certain istance

distance

[versed sun]

flip the input values

distance would be the 250000 number

Spring Clamp
