blueprint

[copper chasm]

oh, so the array is 3 separate strings

[gentle urchin]

Yeah

Each 'depth' of the gameplaytag

My.tag.is.deep
Becomes an array of 4 strings

So with a fixed way of serring up the tags, it simply just works, in regards to UI

Adding new ancestries just works

As long as you stick to your formatting

Create a bpfl function to do the ancestry formatting, and output them as very readable parameters

[copper chasm]

I didn't hit play to see if that would work because I'll cry if it doesn't

[gentle urchin]

It does

[frosty heron]

works

[gentle urchin]

Now bpfl it

GetAncestryFromTag

[copper chasm]

sorry man, thank you for the suggestion, idk if it was a communication error or me just being stubborn and dumb

[frosty heron]

I mean, I didn't give the right node either

out of touch with string manipulation

[gentle urchin]

I used it yesterday luckily

[frosty heron]

Squize saved the day, but yea don't see the use of enum at all in your context

[copper chasm]

you gave the right idea though, I sorted out the parse thing on my own but I didn't know what to do with the array

[gentle urchin]

More fan of text formatting but cant always just use that

[copper chasm]

and then at the end of the day I can just convert string to text (in theory for localization, which is so far removed from where I'm at, but)

[frosty heron]

you wouldn't want to drop all this node, everytime you want to parse the gameplay tag, so like Squize suggest, create a blueprint function library

will end up with much neater and readable codes

[copper chasm]

Yeah, I'll make a bfl for TagToText or something

[tight moon]

Quickly asking here : how do I attach a spawner to 2 different variables ?

[gentle urchin]

Either name it per 'part' of the tag, or genericly for the entire thing, and output all values as separate ones

[copper chasm]

My gameplay tag structure, I'll only really ever need the last part of a given tag

I'm trying real hard to do "Category.Thing.Subthing.Sub-Sub-Thing" etc

But i might as well get all the values, for future proofing

[gentle urchin]

This is to generic imo

As you lose touch with what exavtøy you're getting, except which 'section

Say you change your section in 3 weeks

You decide prefixing them with Mamal. Made semsd

[copper chasm]

I'm not 100% sure how to be more specific - I considered that, but what if I have longer tags or whatever

[gentle urchin]

And now you gotta run around in every bp that uses this. And update the section it uses

[copper chasm]

I do need to check against the size of the array to avoid accidentally getting a non existant index

[gentle urchin]

Instead of just going into your bpfl to fix the section id

Yes, ofcourse,

"IsValidIndex"

Add a bool for success

The entire point, imo, is to reduce the places you gotta fix it to as few as possible

Hopefully just 1

[copper chasm]

given that I don't know how my tags will be structured, how could I make it more specific?

[gentle urchin]

Just pick one now, and update it ( the bpfl function) whenever it changes

[copper chasm]

Just have the return node return every section?

[gentle urchin]

Or one specific

GetXFromTag

X being the specific thing ..

GetRaceFromTag

[copper chasm]

Ohhhh, I see

make multiple functions in the library for each yeah yeah yeah

[gentle urchin]

Ding ding ding

[copper chasm]

(I could make an enum called tagsections and have one function with a dropdown)

that was a joke

Instead of being specific to the type of tag (GetRaceFromTag) Couldn't I just make a bunch of functions called GetFirstSectionFromTag, GetSecondSectionFromTag

nevermind I'm sure I could, off to work

[lofty rapids]

GetFromTag("section")

[tight moon]

Any idea how to make the same vfx spawn from 2 different controllers ?

[gentle urchin]

You could indeed.

[visual ember]

be specific with those names. they are for readability. and sanity

"what was the 4th section again?..."

[copper chasm]

I mean, I'm calling the tag to reference and break apart, I'll see it

[visual ember]

if you have a literal on the spot, yes. if you pass it in, you don't see it

[copper chasm]

Is there a way around this specificity for the fact that each category may have a different tag structure tho? Like, for the races, it's race.nameofrace.nameofsubrace, but weapons may have weapon.ranged.typeofweapon.nameofweapon

[gentle urchin]

Weapons would have its own

[copper chasm]

I'd have a bfl for each category at that rate (I'm assuming I'm just dumb and wrong)

oh I guess I'm not dumb and wrong

[gentle urchin]

You can internally use whatever function you want

Like the first you suggested with just a section index

You can use that internally

[copper chasm]

but for ease of use, it would be best to be as specific as possible

[gentle urchin]

And just hardcode what each wrapper use

[copper chasm]

how come doing it correctly is so much more work 🥲

[gentle urchin]

2 sec, booting

[copper chasm]

is the return node on false just best practice

or did you do it for a specific reason

[gentle urchin]

3

if you dont return with explicit values,

they can be retained from last call

which is terrible to debug 😄

[copper chasm]

I just did this, and I'll do one for each tag "category"

[copper chasm]

I can reuse TagTitle

[gentle urchin]

as an example

[copper chasm]

I'll do the work now so in 3 months when I'm trying to update something, I'm not wondering wtf section was what

[gentle urchin]

Its very small work for the QoL it brings

Now

Id mark the internal as private access

To ensure its not used elsewhere

[copper chasm]

Just mark each function in the library private?

[gentle urchin]

Only the one that shouldnt be used elsewhere

In my case it would be the GetTagSectionAsString one

[copper chasm]

Ohhhh, I didn't use the generic function

[gentle urchin]

You dont have to

[copper chasm]

I probably ought to convert string to text in those functions too, seeing as how they're functionally just for UI display

[gentle urchin]

Makes sense

You can also ensure big first letter if you want

[copper chasm]

more formatting magic

yay

[frosty heron]

\Attributes: {Attributes}, Entity: {Entity}

[spark steppe]

why are the braces escaped?

oh wtf are you even trying to do xD

well, that's not even format to begin with, but make literal text

what is the goal with parameters within parameters?

wouldn't you rather want to escape the inner parameters, if any

i wouldn't use format text to make json....

use a json library?!

[thin panther]

Idk like to know this normal formatting too, because it's not in std::format, c#'s String.Format, token replacement, etc.

[spark steppe]

and this format text hackery isn't?

https://www.unrealengine.com/marketplace/en-US/product/json-blueprint

this is a bit cumbersome to use, but it works at least

idk, if there's a better, more intuitive one

jfc?

[thin panther]

Jesus fried chicken fucking christ

[spark steppe]

ofc it is

until your user enters {FuParser}

and your construct of entangled format text nodes claps it's cheeks

make a struct

use struct to json helper

profit

that's like 3 lines of C++

[woven spire]

how do i move the points in a spline? i cant figure out how to get their transforms or whatever im supposed to do. i just want to snap the end of it to a positon

[lyric basin]

So I am not sure if this is corruption or what, but I have a BP actor that contains a bunch of stuff, works fine. But the name is wrong. I named it Land initially and then later renamed the BP to terrain. The BP in the picture still loads and works, but if I remove it or open a new level and drag in a new instance, the name of the BP is Terrain and when I launch the game everything locks up. Any idea what this is?

I have already deleted Intermediate and Saved, didn't resolve anything

Again, as long as I do not replace this particlar instance of the BP, all is well, but I have to use this in other places so its breaking things when I try to launch

Currently running a validation

[woven spire]

nvm figure it out

[tight moon]

I have a little issue here : the line traced by the node is way too small, but attempts to make it longer (by adding a multiply to the forward vector) only render the debug stationnary. How do I give it a specific size while sticking to the direction of the mition controller (the variable linked here) ?

[lyric basin]

Multiply the output of forward vector node by like 500 and then plug that into the input of the add node

[frosty heron]

thanks for sharing

[lyric basin]

The multiply extends the length of the forward vector to whatever value you input

Currently, it's just spawning and stopping right at the beginning

[tight moon]

The issue is, that doing so locks the debug in a singular direction. I did that one before and that's what happened.

[frosty heron]

multiply by a float

you are only multyplying one of the axis

so what do you expect to happend

[lyric basin]

yeah, I should have specified that

use a double-precision float

you can right click the input node to change it

[tight moon]

It's working now, thanks !

[lyric basin]

if you wanna get really fancy, promote the bottom input node to a variable, make is visible on spawn, and you can edit it from the editor interface

but thats just me being extra

[tight moon]

Sounds fancy indeed, but I shouldn't need that ^^

[lyric basin]

yeah, no, definitely not lol. 99.99% of the time, you set up a line trace and put the values in and never adjust them

I found it useful when testing out different ranges on my firearms

[spark steppe]

xD

#blueprint message this isn't?

well, you came here with issues in that

it's probably not made to handle nested argument strings

and other than the json methods, it wasn't intended to generate json...

[maiden wadi]

What's wrong with the struct to json helpers?

[round geyser]

Hi all

Wondering if anyone could help me out? I'm trying to make it so when dialogue has ended (from a behaviour tree) something happens such as a work vanishes etc

I've already got the dialogue system working, I just can't seem to make things happen in the world based on the dialogue.

[maiden wadi]

I recommend checking out Flowgraph. It makes things like this a lot easier.

[round geyser]

I've heard about that, is that just for a dialogue system? If so, i've already got my dialogue system working

[maiden wadi]

I can do dialog. But Flowgraph is just simply put, a system to control gameplay flow.

[round geyser]

Is it a free plugin?

I'm assuming so

[maiden wadi]

It is. There's a discord for it as well. https://github.com/MothCocoon/FlowGraph

[round geyser]

Thank you my guy, I'll check it out now

[somber tide]

Hey guys, hoping someone smarter than me might be able to help with this vector math:
I have a vector variable which is acting as my custom gravity direction, I want to have my camera tilt to keep this direction as the percieved "down". The idea is to recreate the effect of Super Monkey Ball without actually rotating the whole stage. However, I'm struggling to figure out exactly how to translate this vector into the correct rotation for the camera. Any advice?

[round geyser]

I've not used github before, how do I actually download it ?

[frosty heron]

Is BT based dialogue actually done by any studio? It seems like a giant mess to me

[round geyser]

I saw a tutorial on it a while back and recreated it

[frosty heron]

Youtube tutorial are generally terrible as f

[round geyser]

It's actually really simple and works well, so I thought until I'm trying to make the dialogue choices affect the world

[round geyser]

How would one begin to learn it then ?

I'm still trying to wrap my head around a few things like, if you press choice A, the Ai runs off and does something and if you press choice B, the Ai does something else

[frosty heron]

You can learn from them, there are tutorials that serve better purpose, such as matthew videos because he goes over what node does.

Anything else like, how to make a game in 1 week or inventory and dialogue ones. You need to be prepare to unlearn them.

[faint pasture]

Right now, what sort of data represents a portion of dialogue in your system?

[frosty heron]

A better way to learn is to look at code done by actual devs.

Mostly the content examples

[round geyser]

Understood

[round geyser]

If I'm getting what you're asking, nothing

[faint pasture]

You don't have dialogue working?

[round geyser]

Oh yeah I have it working, one sec i'll show you

(ignore the dialogue options, they're place holders I was messing around with)

Thats 1 npc's dialogue

Fully works

it asks you something and you can reply

[faint pasture]

So you're making an entire behavior tree per dialogue?

In that case this BT IS the dialogue data, just put the ThingToDo inside it

[frosty heron]

Imagine another 20 more dialogues tho

[round geyser]

Yes technically, is there a better way of doing this ?

[frosty heron]

Feels like spaghetti he'll for me

[faint pasture]

Data table full of entries?

Do you imagine there being 100 lines of dialogue in this project or 10,000?

[round geyser]

I have no clue how to use data tables, this just seemed like the easiest way to do it for me

Yeah it's simple for me

Using BTs is a visual way of seeing your dialogue

you can click on the nodes and add code into them

[faint pasture]

If you're going that route just add the ThingsToDoWhenDialogueHappens into the BT

[faint pasture]

it's not scalable but it'll work

[round geyser]

I've tried

Let me recreate what I did and i'll send a screen shot

Basically, I was trying to make a wall be destroyed at the end of a dialogue option

1 sec

I'm assuming i'd put the nodes there?

My friend showed me what to do, i'll recreate it now

(it didn't work tho)

[frosty heron]

Does any node even get executed after the finish node

I highly doubt it

[round geyser]

Not sure

He told me to do this

Clearly, he was wrong

[frosty heron]

Do it before the finish execute?

[faint pasture]

put the thingtodo in the behavior tree the same as any other behavior

Sequence
Say"Fuck yo wall" Wait DestroyWall

[round geyser]

You can't add things like that too it

[round geyser]

Tried, it doesn't work either

[faint pasture]

yes you can

make a task

the task is to destroy a wall

or to call x on x

[round geyser]

Do you mean here?

[faint pasture]

If you're sticking with "I'm gonna make a bespoke BT per NPC and put all their behaviour in it" then keep that energy going

[round geyser]

I'm not that advanced with unreal I've only been using it properly for like 2 months, doing this was the easiest most visual way for me

So what would I use to make something happen ?

[frosty heron]

Make a new task

Your custom task

[round geyser]

Ahhh I get you

[faint pasture]

Start with a move to to prove it out

then make your own task which might be destroy thing

but I'd go more general, assuming you can parametrize tasks, just have it call YourInterface on ActorInQuestion

[round geyser]

I half get what you're saying thank you

How do I actually make a new task ?

[faint pasture]

instead of making a DestroyWall task, make a DoThing task and then you can reuse it for OpenDoor or HaltAndCatchFire or whatever

[faint pasture]

right click and search, same way you make a new anything

task is an asset

[round geyser]

I'll note that down ty

[round geyser]

Do I do it in the BT or in the actual object?

Because in the BT I can't make a new task, unless i'm doing it wrong

[gentle urchin]

Theres a plugin i use for this stuff... that feels so much better ( to me, hate BT dialogue trees for some inherent reason 🤣)

[faint pasture]

Task is a think you make outside

[round geyser]

What plugin ?

[round geyser]

I'll sort it now

[gentle urchin]

Dialogue nodes

[faint pasture]

I mean you gotta figure out how to make tasks and how BT work anyway

once you get it you'll understand why you'd want to make this more data driven

[round geyser]

Yeah with what everyone is saying I think I'll just switch over to a plugin

[maiden wadi]

The green Code button. Download Zip. Worth noting that I don't know if it requires a C++ project. I don't think so, but I've never had a BP only one.

Looks like this. Used in regular event graphs

[round geyser]

Yeah seems more customizable

[round geyser]

[round geyser]

Is the plugin you use free ?

[gentle urchin]

Sort of ? The creator have gone to other avenues and havent clearfied the licence in use..

Forum post suggest one thing, code comment something else

[round geyser]

So if you use it in your game they could sue ?

[gentle urchin]

[round geyser]

Got you, i'm probs gunna go with flow graph

[gentle urchin]

Makes sense

Its also quite aged at this point. Im not sure how different a codebase must be for no longer being under the originsl licence...

[round geyser]

yeah I noticed it's 2018

The game i'm making is really simple, it's just the dialogue affecting the gameplay is whats making this hard

I'm trying to with an undertale type dialogue if you've played that before, where based on what you do you get a different ending

[maiden wadi]

@round geyser We have some dialog stuff planned as well, and it will largely be the same. But I already laid out our new game's tutorial system using Flowgraph. Which is very similar to a dialog system in that it throws a widget on screen, waits for the user to input, then goes on to the next task.

This might be an okay example. It starts the flowgraph. Waits 1 second. Then runs the ShowTutorialPopup until the user dismisses the widget that shows up. That node has data you can specify on it.

Basically binds to the widget being dismissed, requests the widget to display and when suer dismisses, that output pin is triggered, which then stars the 0.1 second timer.

You can branch with it as well and wait for multiple tasks to complete. This shows a tutorial, waits til it's dismissed. Then listens for the player to move their camera in all four directions. The AND only finishes once they've done that.

[round geyser]

I'd love to know what game you're making and that seems way more simple and easier to understand

[gentle urchin]

This seems pretty usefulb

[maiden wadi]

That tutorial stuff is from https://store.steampowered.com/app/2805850/Atre_Dominance_Wars/

[gentle urchin]

Far beyond what it explains by itself lol

[round geyser]

I'm asumming you're using flowgraph?

Also is that your game ?

[maiden wadi]

Correct. What I just showed above is Flowgraph

We're also planning to create a mission/quest system out of it, and possible campaign dialog stuff.

It is an amazing tool as far as creating game flow.

[round geyser]

I'm getting this error when trying to load up unreal with the plugin

[maiden wadi]

[round geyser]

Wow nice! Thats impressive, looking at the game you clearly have experience. I respect that

I used to love playing games like that

[faint pasture]

Does having a colon in your game title hurt SEO?

🤷‍♂️

[round geyser]

I wouldn't

[round geyser]

I'm sorry with all the questions, but do you have any idea why this is showing when loading up unreal with the flow plugin?

[round geyser]

How do I do that haha ?

[maiden wadi]

I don't know if you can do a pure BP project with it. I know some plugins allow that. A C++ project isn't hard though. It's mostly just installing VS and starting your editor from pressing F5 in VS.

I'd encourage asking in their Discord if there are ways to do BP only projects with it.

[round geyser]

Okay thank you

Thanks for answering all my questions people, I appreciate it and i'm sure i'll be back 🤣

[somber tide]

Any clues on this? I have the roll working but not the pitch. Guessing I need the right value for one of the first two vector inputs but not sure where to get it from

[round geyser]

So i've asked in the flowgraph discord and apparently people are using the plugin in a BP only projects

[faint pasture]

Just knowing gravity isn't enough

Gravity defines your down

what defines your forward or right?

try lose the get right vector

that should preserve forward and allow right to "float" to be whatever it has to be to have forward be forward and gravity be down

if it doesn't work, use MakeRotationFromXZ

feed Camera.Forward to X and Gravity to Z

[viscid python]

Hello! I want to make several different enemy models freeze in place and turn blue (like being shock frosted) after using an ice weapon. Is there an easy way to turn an enemy blue or add something to its mesh/texture (maybe a decal?) or do I have to build a separate material?

[spark steppe]

outline material

or custom depth stencil

[faint pasture]

I'm pretty certain the typical approach is to build all this into your master material in some way

if you wanted something that has to be in the surface domain and not just a stencil or post process

[viscid python]

Hmm, the thing is, I have several different enemy models with different materials and textures (some use several materials). So I do not have one master material or anything. I thought about maybe some way to add a large decal or is there a way to replace all materials of an enemy with a single material or the same material (maybe some transparent, refracting ice material) that I can apply to any enemy model?

[spark steppe]

if you want anything translucent/volumetric, you HAVE to implement it in the main material

there's no way to do that in postprocess or overlay

[faint pasture]

Just found out about Overlay, neat

What is that just a 2nd draw call you pay when that's set?

[maiden wadi]

This may be my mistake. Try this.

• Delete the plugin from your project's Plugins folder
• Then go to https://github.com/MothCocoon/FlowGraph/releases and download the top one, "Flow v1.6 - UE 5.4". You're looking to download the Flow_v1.6_5.4.zip
• Unzip the Flow_v1.6_5.4 folder into your project's Plugins.

[faint pasture]

Material instances

[round geyser]

Will that work on version 5.1 ?

[faint pasture]

In the long run you'll be better off just having a couple masters and many instances than many masters

Then you can put FrozenNess as a parameter in your master and anything will respond to setting that value

[maiden wadi]

Oh, same steps, but scroll down the list to Flow v1.6 - UE 5.1 and download the zip there.

[faint pasture]

Or you can use overlays, might be simpler

[viscid python]

@faint pasture Thank you. I am still on Unreal 4.27.2, but still.

[round geyser]

Thank you, I'd install it here? C:\Program Files\Epic Games\UE_5.1\Engine\Plugins

[maiden wadi]

No, to your Project

[somber tide]

Hmm disconnecting the right vector throws everything off and gives me weird diagonal angles, and using MakeRotationFromXZ gives me the exact same roll-only result as before

[faint pasture]

That's to be expected, you're telling it to preserve your forward facing so the only option it has is to modify roll

HOW do you want it to work?

[maiden wadi]

@round geyser EG My project is on a D Drive, in a folder named Projects. And the project folder is PluginTestProject. So D:\Projects\PluginTestingProject\Plugins

[faint pasture]

Try use Gravity as Up and Cross(Forward, Gravity) as Right. Swap the inputs to the cross product if it seems backwards

[round geyser]

Ahhh thank you, i'm loading it up now with the plugin

[maiden wadi]

Should be able to right click content browser and see if it worked immediately.

[round geyser]

Nope it's not working. In the flow plugins folder this is all I have in unreal

And there is no flow section when right clicking

[maiden wadi]

Can you show your windows explorer folder? Where you put it in the project?

[round geyser]

yes 1 second bro

C:\Users\kaneb\OneDrive\Documents\Unreal Projects\Dreams\Content\Plugins

[maiden wadi]

Need to go back one folder.

Plugins will go in the root of your project.

[round geyser]

Put it in the plugins folder you've highlighted ?

[maiden wadi]

Yeah. If the folder isn't there, just create it.

[round geyser]

Ohhh I see

Okay i'll make one now

ty

[maiden wadi]

Should be Dreams/Plugins instead of Dreams/Content/Plugins. 😄 Yeah

[round geyser]

My heads working a little slow today i'm too stressed 🤣

OMG it's working!!!

@maiden wadi Thank you so much!

[maiden wadi]

Now you can be even more stressed learning it. 😄

[round geyser]

Don't know what this guy from the flowgraph discord was trying to do lol

[round geyser]

I won't let scope creep win put it that way

🤣

[maiden wadi]

When you compile, it builds binary folders. But the plugin 'should' already have them and does if downloaded correctly. I guess the main page one doesn't. 🤷‍♂️

C++ stuff

[pulsar geode]

If I wanted to get an actors location with a delay, how would I do that?
I want to get the location of an actor where they were 1 second ago, but I need the information instantly.
I cant simply ask for the location then wait a second so it is offset, I need the request to receive the old location immediately.

[round geyser]

Possibly yeah

[maiden wadi]

Save the location 1 second ago.

[round geyser]

Seriously though, thank you for your help, like I said, I will be back with more questions im sure of it 🤣

[pulsar geode]

How would I go about that? I tried saving it as a variable but it doesnt save cleanly. If the one second delay just started, it waits the whole second. Whereas if it is near the end, the position is very close to the actor rather than the right distance.

[somber tide]

Still seems to do the same thing unfortunately. This is how it looks currently, what I want is for the camera pitch to reflect the forward/back gravity tilt in the same way the roll currently reflects the right/left tilt.

[maiden wadi]

What is this for exactly?Because the usual case for this is like.. Saving an array of vectors every 0.1 or 0.05 seconds or so with timestamps. Then just picking the closest one.

[pulsar geode]

It is for enemies targeting player position. I need them to essentially follow the player with a slight delay, so they would be moving where the player was rather than where they are.

[round geyser]

@maiden wadi Sorry back again, are there any tutorials on the plugin ?

[maiden wadi]

I'm not sure. I just kind of muddled my way through it. I think Mothdoctor did a youtube video on it somewhere though?

[round geyser]

I've watched that video, i'll rewatch it again

[maiden wadi]

Essentially, it is createing a component on an actor which houses your FlowAsset and playing it. Very similar in regards to an AI running a BehaviorTree.

You make a FlowAsset, you put a Flow component on an actor and run the FlowAsset.

You can make custom nodes to do things and trigger outputs that you can place in your FlowAssets.

[pulsar geode]

Huh, I will have to look into FlowAssets then, as this is my first time encountering that term. Thanks for pointing me in the right direction

[maiden wadi]

That was to TooMuch. For your issue it's hard to say. The array of locations thing still applies though. Simply start a timer for 0.1 seconds. Make it populate an array with the current location. If Array.Length > 10, remove index 0. When you want to get the location from 1 second ago, just grab the last index. There are some more elegant ways to code it, but this is a quick and dirty way to test it.

@pulsar geode Honestly though, this is a really rare case for targeting. Interpolation is much cheaper and might be easier.

As in simply interpolate current target position directly to the target. But since it's interpolated, it'll take time to reach it.

[round geyser]

Thank you, I'm playing around with it now

[vestal copper]

hi, is there a way to know in BP that if the EQS succeded or not?

I have a system which uses two movement system one with EQS and one withone eqs (nav mesh volume) and I want to only use EQS when close to the player and fail (which it automatically does) when not close to it. is there anyway to check if it failed or not? and then do some stuff from there?

Not sure why Im struggling to get a correct read from this dot product. Trying to compare the up vector of a scene component to the forward vector of the spline and just getting -1 on print or zero

[maiden wadi]

Are you looking for the spline component's rotation, or the rotation of a spot on the spline?

[manic vessel]

Nvm I dont think the SC is giving transform , just tried it with a Motion controller and itr reading , but think I might try a different method

[iron idol]

does sequence wait until the first line is complete to fire the next? or are they fired pretty much at the same time?

[abstract schooner]

Not sure if I should ask this here, but is it possible to play like an intro videoo after I press Start New Game and have the Loaded game paused in the back ground?
I have a rendered MP4 I want to play in this moment. But I'm not too sure how..
Most of what I see oonline is the starting videos from unreal itself which starts way at the opening of .exe that not what I'm lookking for.

[abstract schooner]

the latter, pretty much the same time. The Sewuence node does not know what comes behind it.

[iron idol]

bummer. thats what I figured. I hate that functions dont allow delays

[gentle urchin]

just use an event 😄

[iron idol]

like a custom event?

I mean I have one that fires in the event graph, but the problem is I need the rest of the code from the function to fire after the event

how does the pin at the end of poison damage in this example work? I take it its like a sequence, it fires the code simultaneously and continues on? It's within a function

[wanton goblet]

So I'm still learning how to get foreachloops to function the way I want, I've got this system, which spawns a spike cluster that is supposed to grow and rotate slightly, with a timeline driving a lerp, however it only ever runs on the first item in the array, when I want it to run on all of them simultaneously.

[empty marten]

Try putting the timeline in after the ForEachLoop before the Grow and get rid of the sequence node.

Cos going off that, what you're telling it to do is go through the ForEachLoop and then only once, use the timeline.,

[wanton goblet]

@empty marten just tested that, it's still only operating on the first index of the array

Not sure what I'm missing

[empty marten]

I think you're not randomizing the rotation and vector so all of them are in the same exact spot.

[wanton goblet]

they're different spikes, so that would be noticable

it's only operating on the relative rotation

I can see the other spikes, they just aren't scaling

[empty marten]

So something you can do is use a print string node quick to see how many times its looping through that array to see if its only get 1 result or all of them.

[wanton goblet]

sure, one sec

[empty marten]

So after grow just put a print string

[gentle urchin]

You'd want the loop in the timeline

not the other w ay around

Timeline -> ForEachLoop ->

For each timeline tick you want to loop and modify all items in the array

[wicked wraith]

Man Timeline -> ForEachLoop

[empty marten]

I think these guys have a better answer than I.

[wanton goblet]

@gentle urchin that's what I had set up previously, but it didn't work either

[wicked wraith]

But for more elegant way, you can just get the array variable and attach in the "target"

[gentle urchin]

no you didnt

this is not it

[wanton goblet]

Can you clarify please?

[wicked wraith]

Add the For Each Loop here

[wanton goblet]

Would that run off the update pin?

[gentle urchin]

yepp

[wanton goblet]

ok, let me try that

thank you!

that worked!

[gentle urchin]

i know, we're brilliant like that

we just post working solutions

/joke

[wicked wraith]

Do you understand what happened for work now? 🙂

[trim matrix]

this guy is terrible lol

[gentle urchin]

we've all started somewhere

[trim matrix]

sure but this is ...

[gentle urchin]

someones starting place

You should've seen my first snippet

following some youtube pleb

"oh yeah this is easy!"

anyhow

[empty marten]

Wait, I'm confused as to how switching around the timeline and the foreach was the solution?

[trim matrix]

it would loop and start at frame 1 at all time

[wanton goblet]

@gentle urchin @wicked wraith thanks for the help

[trim matrix]

starting at the starting point and never moving

[gentle urchin]

especially when "play from start" was used

[trim matrix]

thx

[wicked wraith]

Because you are starting the Timeline multiple times setting the For Each until the timeline

Think the ForEach will "play" multiple times (following the length of the array)

[gentle urchin]

reading it out loud it sounds like it wouldnt work ..

"For each element in my array, start timeline from the start , do something based on the timelines position on it's curves"

[empty marten]

Oh ok. I get it now. I opened MS paint and draw a line to represent the rotation so as it goes round it set the vector.

[pseudo fulcrum]

Any way to have a string map to a byte array than just byte?

[gentle urchin]

huh

guess you'd make a function for it if it doesnt exist

could check LE Extended

there we go

[trim matrix]

this is for data saving?

[cosmic aurora]

my character keeps doing very small "twitches" left and right, when following my mouse movement (yaw rotation) and I have no idea why, is there a way to debug this?

[tawdry walrus]

Is there a way to create a dynamic enum?

[maiden wadi]

O.o Why the rudeness?

Oh. You. Nevermind. Carry on.

[storm obsidian]

hi have a probably stupid question but
any way to multiply (or do any other math) with every single value in struct?
in my case struct contains only float values

[gentle urchin]

foreachloop -> *

wait, no

is it a c++ struct

comes down to making a function for it anyways im afraid

[maiden wadi]

Pretty much.

Some functions like Vector have special handling functions already made, but if it's yours, or there is no function, then it's up to you.

[gentle urchin]

In a quest system, would you think it's necessary to store anything beside the static data once it's completed ?

perhaps a timestamp and whatnot if it's that kind of a game, but otherwise not important right?

not even sure what this extra data would be tbh

branching quest chains are simply different quest chains

so..

[maiden wadi]

Depends on the game type I guess. And what you want to display.

[gentle urchin]

probably just that it's completed

quest log could still show each step,

perhaps if some tasks were optional, they'd show that

[heady lantern]

Anybody have an idea how to properly center the pivot point? There are an odd number of pixels, and I can't set the pivot point to decimals. When I rotate the wheel from blueprints, it wobbles because it's not properly centered. 'Center Center' Pivot Mode produces this same result.

[maiden wadi]

Like after it's finished, It's rare to need much more than the ID, Status(Failed/Completed), and a timestamp. Timestamp sometimes is overkill unless you want to do like non backwards compatible achievement granting and stuff.

[wicked wraith]

Create a widget add your image and your functions (if have) and add the widget in your main widget

[storm obsidian]

me too, but seems like i should to do that

[wicked wraith]

You can set the pivot point as .5 too 🙂

[gentle urchin]

Right, exactly what I'm thinking

[maiden wadi]

Be careful with displaying images in non whole pixel counts. Unreal will blur it by mixing the pixels.

[gentle urchin]

this looks like some design problem

powerof2 is a rule for a reason when it comes to textures @heady lantern

[heady lantern]

It autocorrects it to the nearest whole number. It won't let me input decimals.

You're saying to make a new object, and make the Sprite object a child of that, and rotate the parent object instead?

[maiden wadi]

It really is better just to make a p2 texture for anything. If you need it that same style, then linearly scale the image, and offset it by one pixel. Then you can display it in Unreal using mips and it'll look better.

[cosmic aurora]

haha I fixed it, I had "use controller desired rotation" on! Half a day wasted on this lmao

[heady lantern]

I've not heard that reference before, p2 texture. Not sure what you mean by that. All of the game logic is done for the vehicle in blueprints using Sprites and Sockets, so if I were to change these to non-sprites, I'd have to change the blueprints quite a bit.

I suppose I could multiply the resolution by 4x, scale it properly, and set the center to the middle of the 4 center pixels, but I'd rather use pixel perfect source textures, mainly for the asset creation workflow.

[gentle urchin]

p2 = Pow(2)

power of 2 size, 2,4,8,16,32,64 etc etc

in your case 32 by 32 would probably work well

32 by 32, can hardly tell the difference

[heady lantern]

Ohhkay, I gotcha now. I see what you're saying.

Much appreciated everyone!

[maiden wadi]

If you have a 31x31 texture and you scale it linearly to 62x62. That's x2 size. Add a pixel on each side. You now have a 64x64 image that will display exactly like your 31x31, except that you can offset it by perfect center now. And Unreal will still display it identically because even though it's 64x64, you can scale it to 32x32 and it should look the same as what you started with. Except centered.

[gentle urchin]

the extra pixel must go somewhere 😛

[heady lantern]

Perfect, I gotcha. I kind of figured that might be the solution. I wanted to avoid modifying assets after import as much as possible, to streamline the process. But I should be able to have a separate import profile for the tire assets specifically to automatically scale them, that way I don't have to modify the assets I've already creeated, or change my workflow. I think my confusion came from other game engines having different pixel pivot modes, such as Godot you can pivot from pixel center, or from pixel corner. With the Unity system I was using before, it would ignore the pixels for the pivot system entirely and give local coords. That would be a nice feature to add if they ever updated Paper2D, lol.

[gentle urchin]

(cant you here manipulate pixel size or something to get the desired effect?)

found it

turn that off to freely set the pivot

under Advanced

[heady lantern]

In Unreal? Probably, but I'm least familiar with Unreal. I'm making the basics of the game in Unity, Godot, and Unreal to get a feel for which of the modern engines I like best. Obviously a pixel art game isn't the best use-case for Unreal, but I really just want to learn modern blueprints and stuff.

WOW

[gentle urchin]

but power of 2 texture is still better 🙂

[heady lantern]

Yeah, that'll work for now at least. Didn't realize that was a setting. It's basically the same setting for Godot that I was looking for initally, lol.

Thanks everyone for the assist! 😛

[sinful pawn]

Hi, i have a question you know is some countries the car when you pass your driver license have shared control over the car like the driver have the full setup and the monitor can also like break etc... how can i achieve this sort of thing in unreal having two players controlling one car (pawn, character or actor i don't know what to choose.).
If you have some idea on how to make this i would like to hear it ^^.

[maiden wadi]

Make a car that has basic controls. Turn, gas, brake. Etc. Make some form of pawn. Most people do this via "seats" since they also attach the old character to them when they enter the car. The player possesses the seat, which is attached to the car. And the seat uses it's inputs to push inputs to it's attached vehicle.

[copper chasm]

I'm gonna put my head through my monitor messing with this ui

[sinful pawn]

So since I don't need them to exit the car i just make pawn that are attached to the seat and make custom event for each input like gas brake etc... and in the pawn i called those event ?

[maiden wadi]

You could just make a Car. And then make a Seat. In Car's beginplay you spawn two seats and attach them to the Car. Then get both players, and possess the seats.

In the Car you'll make custom events for Gas, Brake, Turn.

In the Seat class, you can put your inputs there. Gas, Brake, Turn. And you'll get the Seats's attach parent, cast it to car, and call whatever correlated Gas, Brake, Turn you need off the input event.

[maiden wadi]

What UI? 😄

[copper chasm]

well, because I am not happy unless I'm struggling, I decided to flesh out the character creation ui before I redid the code, so I can test it as I go

and, because I am as dumb as an upside down blender, I am entirely befuddled by the concept of anchors

I set up the canvas panel, I set it to view as desired on screen, I position the things where I want them, I hit play, and they are not where I thought they would be

[sinful pawn]

That sound exactly like what i want i will try it tommorow thank you for your help

[maiden wadi]

What are your anchors and such?

[desert juniper]

have youj tried watching some tutorials on anchors?
it's a pretty simple concept that shouldn't take more than 5mins to understand really
https://www.youtube.com/watch?v=hIz9Ft6a4mY&pp=ygUOdW5yZWFsIGFuY2hvcnM%3D

maybe better to take a step back and learn / understand how the ui system works may help some headaches

[copper chasm]

I'm just whining, I'm sure it is (like most things I whine about) much easier than I'm making it out to be, and I'll have it sorted in a half hour or so

[maiden wadi]

TBF, anchors take some mindbending for some people. UI layouts in general do. I had it easy when I started doing UI in Unreal, because I had fun making WoW mods. All hand edited XML files that make you get good at visualizing things. Meanwhile Unreal actually visualizes it for you. 😄

[desert juniper]

maybe it's because i come from web dev where I'm already used to creating reactive UI

[maiden wadi]

Ugh. Web dev. Makes me happy I ditched college for that when I started. I'd need a padded room by now.

[desert juniper]

what? web dev is great! you just have to install all these dependencies, and frameworks. anod then you have to just simply install and configure transpilers. oh and then theres typescript so that you can write typesafe code! you just have to sometimes look at SO to figure out the correct types to import / use
it's great!

[maiden wadi]

[copper chasm]

tah-dah D:

i just have to sneak a button in there for the base widget

I was setting the brush image without setting the image size, so the image was warping all weird, and I was trying to fix it in the vertical box or something so it was then stretching

idk man, I just be clickin' buttons sometimes

it also just looks weird, because I expect the canvas panel to be the "viewport" and so when the widget is outside of it I get confused

[copper chasm]

I'm having a brain fart - I have the above widget, each box is the same widget, just using a different gameplay tag to populate data from a DT to fill it in. I'm trying to set up an on button hovered event in the master widget (the button is the picture) to display info about the hovered ancestry. On the "hud" widget that is showing all 8 buttons, do I need to make an array of the individual buttons to check for the onhovered event?

[surreal peak]

No, you expose an EventDispatcher/Delegate for the UnHovered with the Widget that contains the Gameplay tag as a parameter. Then you bind to that Dispatcher in the outer widget

And of course call it in the inner one, passing self along for the param

[copper chasm]

ohhh, I wasn't passing any data along with the dispatcher

that would do it

[copper chasm]

I think I might have done it backwards, but the only way I'm getting it to work is to get all widgets of class (the box class) in the code before I bind to it, that may just be how you do it I'm not sure

It IS working tho, lol

[surreal peak]

Aren't these widgets inside of the widget that wants to bind?

[copper chasm]

so there's a widget called AncestryBox that takes the gameplay tag and builds itself off a datatable, grabs the picture and the name, and then there's a widget called CharacterCreation that has 8 instances of AncestryBox in it where I've set the tags up so it makes the above window

I've named all the instances of AncestryBox (DwarfBox, ElfBox, etc) - I can manually set each individual one's onhovered, but that seemed incorrect

[surreal peak]

Where do you want to listen to the hovered event?

In charactercreaction?

And are the AncestryBox widgets inside some grid ?

You shouldn't need to get all widgets of class

If you want to bind in the CharacterCreation widget then just grab the 8 AncestryBox widgets

If they are in a grid, grab the grid and loop over its children or so

Or manually pull them into the event graph and add them to an array on Construct

[copper chasm]

Yeah, there's a textbox in charactercreation that I want to display text stored in the same datatable the texture/name is in

They're in a vertical box with 2 horizontal boxes

I can make an array in preconstruct easily enough

[surreal peak]

Put them into a geid

Grid*

And loop over the children

Vert + 2 Horizontal boxes is just a grid with 2 rows

Replace the setup and you can use the grid as your container that you just need to loop over to bind to the delegate

+- casting to AncestryBox of course

[surreal peak]

Or that fwiw. Grid is cleaner though

[copper chasm]

I just had to fix my positioning on stuff, but I swapped it to grid

Fair enough, that works, and will save me headaches when I add more ancestries

thanks

[maiden wadi]

CommonTileView is best. 😄 But that requires data objects.

[ancient moth]

how gut I get a listeview entry list item widget and call a custom event on it, or just tell the listview to redraw it?

[elfin gull]

I've run into an odd one, that I wasn't expecting... Working on some helpful Blueprint Function library stuff, and doing debugging/logging at the moment. I create a function "LogMessage", and I have an ENUM that has message types. Depending on the message type, there is a prefix added to the message, and then the date/time is added, and finally the message. Great, simple and sweet little function. HOWEVER... It only prints to the screen. It won't print to the console log.

If I copy the exact node setup into a specific BP in a function in said BP, for example, "LogMessage", and use that, it works fine printing to the screen and to the console log. Anyone else run into this weird issue, is it a known thing? Or is there something causing this with purpose? It's driving me mad and I've wasted too many cycles trying to figure it out, heh...

[molten pike]

I've got some actors in world space displaying text render components above them as navigation aids for the player. Any idea how I can get the text to render "through obstacles" such that it's visible on top of everything except the player? It's already set up for rotation and scale, just need to be able to see it through the trees.

side-quest, what's the easiest way to make the text lit so that it shines through shadows?

[elfin gull]

It turns out it was a context issue... Not sure how to resolve that elegantly, but a hacky way was to make a "LogMessage" function in my custom GameInstance, and copy the node setup in there for the logging function, and use the Blueprint Function Library version to just pass the message through to the GameInstance function.

Since GameInstance always exists and has a global context, it works... But it feels wrong.

[elfin gull]

The quickest solution I can think of, is using a custom depth pass. You could also move over to UMG + materials, and then you can have at it concerning making the materials used for elements unlit and even emissive.

[molten pike]

Is UMG a blueprint component?

[elfin gull]

It's the UI system in Unreal Engine

[olive yarrow]

why in allahs name will this static mesh not launch? It's on an Actor so i can't use launch character 😦

[elfin gull]

Text render components are good for quick and dirty testing and other stuff, UMG is for UI/HUD and what not. But you can also use UMG for elements in the scene, such as a health bar floating above an enemies head, waypoint markers, etc. UMG is a complex part of UE, but something definitely worth breaking ground on

Is the mesh physical and all that?

[molten pike]

Cool. Right after I got everything else about it working 😂

[frosty heron]

try add Impulse?

[molten pike]

Yes, the mesh is physical inside the BP, but the mesh is optional to allow for Navigation labelling areas as well as things

[olive yarrow]

no dice, thanks though 😦

i coulda sworn this was working last night... the joys

[molten pike]

I'll give that a look. Thanks!

[olive yarrow]

i didn't check velocity change

sigh.

[fickle lichen]

~~Update... So in regards to my waypoint system that is not changing its units properly I've come to realize that the distance to player system part of it is broken. 🤷🏾

So I guess that is what I will have to fix.~~

https://tenor.com/view/the-princess-bride-inigo-montoya-meaning-are-you-sure-of-that-gif-7536490

[humble matrix]

yes it does

oh god

it froze

what happened

i had to get task manager lo

l

[runic parrot]

Hi everybody!
Any idea on why this static meshes are not generating navigation?

[lunar sleet]

Generating?

That checkbox makes holes in the navmesh it doesn’t generate one

[runic parrot]

So what should i check so that the static mesh is viable for nav generation?

I have this other plane and it generates okey

Not sure what is the difference, the plane also has a "static mesh"

[lunar sleet]

I mean normally you just put a navmesh volume but if you want runtime generation use an invoker (they can be expensive afaik)

[runic parrot]

I do have an invoker on the pawn already, it works okey for the plane

but not for the hexagonal tiles

(First picture)

[lunar sleet]

It’s not usually a good idea to do that (invoke navmesh on a pawn)

[runic parrot]

I can make it more efficient later, like when zones are created, spawn an invoker that covers all the zone and do it while the screen is loading

that's not my problem at the moment

navigation is just not working at all in the tiles : (

[lunar sleet]

Is this fully proc gen?

[runic parrot]

The first picture, the ones with the Hexagonal tiles, it's just spawned actors with a static mesh

They are proc generated, yeah.

[lunar sleet]

Ok but I imagine the floor or at least the level exist

[runic parrot]

Actor:

[runic parrot]

Yeah, the actor is the hexagon and it has a static mesh for "graphics" and one for walking "Floor".

The floor is supposed to be the one for navigation, just a plain flat hexagon

[lunar sleet]

Ok, so just drop a navmesh volume on it, no invokers needed

But as far as your tiles go, you might be having issues due to step size or if character can step up on is turned off

Try #gameplay-ai if you can’t figure those out

[runic parrot]

oh, that sounds like a better place, thanks!

[copper chasm]

So I've got my grid of 8 buttons, I make my array from the grid, I assign onhover functionality to display information outside the grid

I'm trying to set it up so that when I click on one of the buttons, it changes tint, and any other button that may currently be tinted loses its tint, but I think I have a fundamental misunderstanding of foreach loops. I can make them tint on click, but I'm not sure how to untint the rest

[frosty heron]

so like just "deactivate" all the other buttons then "activate" the button that is selected

my button widgets have states

when they are active (selected) and when they are not

On Button Click -> Get all the buttons -> Deactivate -> Get the selected button -> Activate

[copper chasm]

I just had to run another foreachloop on the click event, i got it

[frosty heron]

You run "deactivate" state on each of the button you want to deactivate

[copper chasm]

I like that "activate" sound

Yeah, I was just using the loop incorrectly

or rather, not using it correctly, lol

[frosty heron]

perhaps there's a better way if you have hundreds of buttons

which is possible if it's something like items

actually you don't even need to loop...

just store a reference to the last selected button

Last selected button -> Deactive
Current selected button -> Activate

[gentle urchin]

This is the way

[frosty heron]

@copper chasm exactly what I did for my widget

[frosty heron]

lol I must have got a brain fart when I suggest the loops

[gentle urchin]

If lastbutton != none -> deactibate last .. etc

[copper chasm]

this works right now, but I'll try and chip it down to the function to just check against the previous clicked button

I like how I was absolutely zooming along on the data end, and then made a detour to make the ui look a little nicer and now it's been two days and I haven't touched the data 🙃

[frosty heron]

I would be against doing the loop

if you look above, the code can be much simpler

actually all other buttons are irrelevant

only the one you select and the one last selected matters

Think about other use case too, where you want to play animation on button Unselected

u don't want to run that animation on all buttons, just the one that is last selected

if you don't need to loop through all the buttons, don't

[gentle urchin]

Far better 🤓

To avoid it

[copper chasm]

well you know what they say, ask 100 developers the same question and you'll get at least 50 different answers 😛

i'll fix it

[gentle urchin]

Nobody (but Cold) would suggest a loop 😂

[copper chasm]

this discord channel has been one of the most illuminating and frustrating experiences of my adult life, insofar as education is concerned 😂

[versed sun]

im thinking you should use GAS

[maiden wadi]

Yeah... It has that effect. 😂

[copper chasm]

and like, the stuff I'm doing isn't stuff people usually make low level youtube tutorial content for, so it's just me doing it poorly until it looks right, asking here, and slowly retrofitting and re-parsing and trying not to belittle myself lol

[copper chasm]

funny story, I was originally using GAS for my turn based grid combat, but then I hit a wall because I couldn't figure out how to apply a turn based timer to my GE's without a ton of extra coding just for that, so I stopped going down that road, and then like two months later someone was just like "you could just make the turn manager in BP and use infinite GE's that you toggle on and off" and I unplugged my PC and went to a park

[maiden wadi]

Lol, yeah. 😄 We're using GAS, and all of the gameplay mechanics are designed as turns even though it's technically realtime. As in a turn takes so long and every so often the game "ticks". What we have though is an ability on the GameState which runs when that happens. That ability basically drives the backbone of the gameplay systems.

[gentle urchin]

Interesting approach

[frosty heron]

hands up whos using GAS 😄

too good to not be utilized imo

[maiden wadi]

Wait, how do I have three hands?

Gotta figure out how to deal with this license thing on the heavily modified dialogue plugin im using...

Unclear license is no good

[maiden wadi]

Email the creator. 🤷‍♂️

What license though?

[gentle urchin]

Creator went a-wall

Moved to china, pursued other interests

Licence for use /modification?

[maiden wadi]

Yeah. Which one is it?

[gentle urchin]

It has none specified

Documentation says all rights reserved

[frosty heron]

@maiden wadi would it be very important to use tile view? I never venture there but I do plan to display hundreds of items at a given time.

never feel limitation as I am working with very small data atm

[gentle urchin]

Its an optimization

Basically recycles only the visible amount of tiles

[frosty heron]

Yeah, just hope I don't have to refactor a lot of things

if turns out I need to use tile view

[gentle urchin]

Thats a big refactor

You can manage this yourself with some cheating and creative handywork

Without being forced to uobjects

[frosty heron]

for multiplayer items, can I just use structs :P?

i mean sure can, but maybe UObject still better

[gentle urchin]

Uobjects have many benefits 🙂

[maiden wadi]

It's not such a major refactor. You're creating widgets and passing them data probably. If that data is not already wrapped in a UObject, then make a new UObject. Make the UObject instead of the widget, give it the data. Then just give all of the objects to the tileview.

Go to the display widget and add the interface, override the object set function, cast to the passed in object to get data, set up widget as you were already doing.

[gentle urchin]

^ yeah thats pretty straight

Just wrap it in uobject on its way ti tileview

[maiden wadi]

You don't have to change the using system entirely to UObjects at the start, just use them to wrap data for now.

[frosty heron]

Right, but you would re-create those UObjects from an array of item struct I suppose?

[gentle urchin]

Smart move Auth

[maiden wadi]

Pretty much. And you can pool them if you're worried about object limits.

[gentle urchin]

Instead of itemwidgets, youd create uobjects to wrapp each struct entry

[frosty heron]

Ahh yeah, that sounds great.

thx

[maiden wadi]

I hate displaying struct inventories. Converted enough struct based stuff to tileview/listview. 😂

Im still on struct inventory 😦

But !

I made my first replicating uobject a few days ago

So the future is bright 😁

[maiden wadi]

Nice. 😄 UE5 made the handling with that so much smoother.

Like you don't even have to do the complicated stuff anymore. Just make the object and add it to the replicated subobject list.

[gentle urchin]

And set it to be consideredfornetworking?

Or is that redundant now?

IsRelevantForNetworking or whatever it was

[maiden wadi]

Ah, yeah in the object itself, you still need the override for that

[gentle urchin]

And also add the bp GetLifetimeReplicatedProps

Aaaand if you want RPCs (i dont, yet) there was another thing to setup

[maiden wadi]

I wonder if they'll ever fix up the outer issue for replication.

[gentle urchin]

What issue is that?

[maiden wadi]

If you Rename an object into a different outer. Like I was doing to transfer one item from one inventory to another. If the original outer is destroyed, item kapoofs. Cause despite being outered to the new object, and added to the new owner's replicated subobject list, it's actually still networked through the original owner.

So to transfer, I started to copy the items into the new outer instead of trying to use the old one.

[gentle urchin]

Interesting

Did you remove it from the old inventorys replication list?

[maiden wadi]

Yep. Uhh...

This is my basic remove/add code.

[dark drum]

I believe there's a free plugin for replicating uobjects.

[maiden wadi]

This is the buggy code using rename.

[gentle urchin]

Does the item remain on the server ?

[maiden wadi]

On the server it's fine. If you destroy the old outer, Server stays correct. But every client loses the item from the new outer. 😄

[gentle urchin]

Does it change net id or something when it get renamed?

Hmm interesting tho

Maybe ill give it a shot 😂

Is outer changed on clients aswell?

[maiden wadi]

No idea. I didn't dig deep enough into it. Last thing I need is a tunnel into networking code. 😂 I have enough shit to do and learn as is.

This was my eventual "fix" for it. Just duplicate it into the new outer as a new object.

I need to add more logging to my stuff. Just gonna go bloat classes someday with FFrame::KismetExecutionMessage and FMessageLog("PIE").Error()

[gentle urchin]

Seems i was on the right track

[maiden wadi]

Hmm. I feel like that was a slightly different issue though? Cause I do have an OnRep that does that.

I don't remember what bug this was for. But this doesn't help the item changing hands on the server.

[gentle urchin]

Imagine the onrep not being called

Or was it ?

Should only happen for nulling the old pointer i'd think

[maiden wadi]

It is. This specific issue isn't a rename issue on the clients. This is the server no longer replicating that item at all. So client loses the data to it. Like when I was testing it, both server and clients had the correct outer. Everything seemed perfectly fine. New outer had the item in it's replicated list. Old outer did not. Delete the old outer and it remains on the host, derps on client.

[gentle urchin]

Ah ok

Deleted old outer , the inventory comp (or whatever container it was)?

[maiden wadi]

The actor it was on, yeah. I think I had just some replicated box actor.

The use case was drop actors I think? Like loot everything and the actor is destroyed.

[gentle urchin]

Guess ill need to test that scenario

Rename sounds convenient

First id need to rework my inventory 😂

[maiden wadi]

Hopefully they fix it. 😄 But I don't mind the copy. My inventory items are tiny objects anyhow. Literally basically an object with a pointer to a definition and a struct that has an array of Pointer/Floats

[gentle urchin]

Pretty much same as my structs 😆

[maiden wadi]

🥳 Primary weekend projects done. Refactored my plugins into a single plugin with multiple modules and got a good start to a game settings menu that uses the GameSettings plugin from Lyra. Styling is terrible still.

[gentle urchin]

Woop woop! Well done !

Wish i could do such work in a single weekend lol

I gotta spread it across weeks due to time constraints 😂

[maiden wadi]

The above took me ~4 hours. I could probably do it again in about an hour now though. I think the original took me about two days because I was pulling stuff from Lyra and trying to make it more modular without needing Lyra itself.

[gentle urchin]

Once my plugin is done im gonna need to find some volunteer for some feedback om it 🤣

Dont trust my own approval for my own stuff , kinda biased I think 😆

Just gotta complete the refactor and check that it actually works

[maiden wadi]

Oof. The fun part.

[gentle urchin]

Well its almost there now. Switching to Uobjects was less work than i imagined. Now i just gotta setup the correct and logical delegates for the clients

Nested uobjects but lifetimes makes it pretty unusable to have delegates on a per object basis

Which I only realized after i had them setup...

[kind lotus]

How to stop the sound if the sound is pressed again while its playing

to be exact the flash light has a double click sound

if i press too fast u hear 4 clicks
but i want it to be 3 ( like overrides the previous sound)

[maiden wadi]

Rather than playing a sound. Put a sound component on the character instead and use that to play, so that next call overrides the last on the same component.

[kind lotus]

this right?

[maiden wadi]

Sorry, wrong wording on my part. AudioComponentis what you're looking for.

[kind lotus]

TY!!

[proud bridge]

hey, the OnAudioPlaybackPercent_Event is not triggering even when the audio component is playing a sound. any help?

[maiden wadi]

Likely an optimization. I didn't look at code, but did test a bit in a more simplified manner. This works.

This does not.

[proud bridge]

so that create event "customevent" is the bottom custom event?

[frosty heron]

yeah, for it to appear, it needs the same signature.

you can select any events that have matching signature

[proud bridge]

doneeee!!! thanksss! ❤️

[floral stump]

why i can't delete a node?

this started to happen today

when i restart the editor, everything works, and after an hour or two, its like my mouse locked down

i can't move anything in world and can't delete nodes or move them

[sick sky]

i sometimes had this bug

reload the BP

(recompile the BP/edit/close/refresh it someway)

[floral stump]

restarting the BP fixes the issue only for BP class

the items in world/viewport still don't want to move

[sick sky]

thats some weird shit

honestly, at this point try to record when you dev, and as soon as your are stuck stop the record and rewind to see what could of get you stuck
do that multiple times and see if there is a common thing

[floral stump]

this happened when i hold lmb for few seconds on world items

but the interesting part is, this only happen when it need to, not all the time

[sullen moat]

Would anyone be willing to look at one of my functions for my inventory system? I'm having an issue calculating the size of the item versus the available size in the inventory container and pulling my hair out

[maiden wadi]

What determines your sizes?

[rugged wigeon]

Just post the code

[floral stump]

this is one of the reason i don't use bp for inventory component
this whole function could take just 10 to 15 lines of code in c++

[rugged wigeon]

Well… why are there two for each loops with no array to iterate over?

[sullen moat]

Those are meant to loop through the inventory container X&Y and ensure there's space in the container for the item,

[rugged wigeon]

But you are aware that they’re not doing anything right

[sullen moat]

yeah I know, multiple issues with this bp lol

work in progress

working by myself so I've been using chatGPT

[rugged wigeon]

We are in a cursed future

[sullen moat]

hahaha

[woeful pilot]

Does anyone know how to spawn level instance in a construction script. I’m trying to get them to spawn along a spline, i can get packed level instances to spawn but the level instances themselves won’t spawn in the construction script. Even more frustrating is that using the level instance variable when exposed for references only targets Packed level instances. I’m stumped

[rugged wigeon]

Start by breaking it up to little things. Make a function that returns true if the inventory is full or not. Make a function that tries to get the first open coordinate to put an item in.

[rugged wigeon]

You don’t do it in construction

[sullen moat]

Yeah I had this thing commented out but I don't think I saved it. I have bool that returns true if the inventory slot is occupied, if inventory slotX and slotY are < available slots in the slots array then it should be placed

also have stacking functionality

[woeful pilot]

Why and can you be specific because it works with packed level instances fine

[sullen moat]

After looking at the bp, here's my current issue. I'm trying to loop through the temporaryOccupiedSlots array to ensure the new item fits in the OccupiedSlots array, but my problem is I'm using a vector for the item size and I'm having an issue retrieving those values for the forLoops

[rugged wigeon]

Your loops still don’t make any sense. You’re saying for each item: for each slot: for each slot: set the value of item size to 0.

And then you pass this value of 0 to make a struct that does nothing

Like why are you looping over the slots, Twice, and not doing anything with the slots?

[rugged wigeon]

You’ll probably get weird life cycle issues even if you manage to force it to load level instances during construct. Note how spawn actor is disabled in construct scripts. Loading level instances is a much slower thing.

At most you want this logic to be callable in editor imo

[rugged wigeon]

I think that was me. But this shouldn’t be surprising really. A timer is a timer. A turn timer is not a timer at all. It’s a listener for turn end events. It could go forever.

[dreamy sail]

is there a way to find out what specs are needed to play a game that we created ?

[fickle lichen]

I'm not sure #blueprint is the right channel for this

So I'm setting up seamless travel, and I've read that it will bring the gamemode with it between maps. Given that this makes map-specific gamemode overrides no longer possible, how should I be defining map-specific values?

[maiden wadi]

Can't really do much more than profile and guess. Or test on actual hardware via testers or hardware you have.

[maiden wadi]

It swaps out the game mode. All gameplay actors are replaced. There's just a handoff that happens, like with PlayerState's copyproperties calls and such.

[fickle lichen]

When using seamless travel, it's possible to carry over (persist) actors from the current level to the new one. This is useful for certain actors, like inventory items, players, etc.

By default, these actors will persist automatically:

• The GameMode actor (server only)
  • Any actors further added via AGameModeBase::GetSeamlessTravelActorList

[dreamy sail]

thanks

[nova imp]

Would anybody happen to know a way to implement an array of world location into a material.(I am trying to make a pulsing effect on a laser beam that repeats at a certain frequency) I am currently using a sphere mask and moving the coordinates with Blueprints. But this method only works for one pulse per material. I have tried using a render target but cannot seem to get the value from the texture back into world space. A push in the right direction would be great thanks in advance.

[maiden wadi]

I'm unsure. I don't believe we did anything specific at work, and we use seamless. I fucking hate it, but we do. And we have a completely different gamemode in the combat map than the world map.

[maiden wadi]

This seems overkill for a pulse effect. You shouldn't need much more than a start/end point and to sine the pulses in between them at theintervals.

[nova imp]

Sorry I missed a part, the laser can then bounce of a surface creating a new Actor that needs to have the same rythm with the pulses

[nova imp]

Oh shit you're right I'm overcomplicating it thanks so much 🙏

[maiden wadi]

Could always go nuts with a niagara ribbon though too.

[wanton radish]

help, for some reason my pistol when droped doesn't generate hit events with enemy actor, but it does with my character actor.

[maiden wadi]

When dropped, are you simulating physics on the pistol?

[wanton radish]

yeah

and it flies, touched me (hit event), toches enemy (no hit event)

[maiden wadi]

Do you have this enabled?

[wanton radish]

now I don't have, but I had it enabled and same result

btw in which actor should it be enabled?

[maiden wadi]

It should be enabled on the component that is the root of the simulating physics.

[wanton radish]

so my pistol right?

@maiden wadi and there is weird thing, sometimes when I throw that pistol under enemy's feet and he starts bugging on that pistol it generates hit event.

[shrewd tiger]

Hi guys
Is there any smart way of getting a 2d isometric outline of a mesh ingame/in runtime?

[astral mist]

I think that's two problems in one, the isometric view is a projection technique in this case -- Then the outline is a material or post technique

[shrewd tiger]

Well I mean like a cross section

The outline of the isometric projection

[versed sun]

yes, do you need it as a texture2d?

[shrewd tiger]

Yes

[versed sun]

you want like a alpha, right?
like Star, or Heart?

or full color ?

[shrewd tiger]

Alpha

[versed sun]

you can use a Scene Cap Component2d, set to Orthographic
The Ortho width will be how big the Texture is (256x256)

[shrewd tiger]

Thanks a lot!!

[versed sun]

it will be a bit of setup , but it should get you on track

[wanton radish]

Help, when pistol collides with enemy it should generate hit events, but it doesn't. Why is that? It generates hit events with my player.

[iron idol]

This probably doesnt go here so I might need to ask somehwere else. I'm packaging my game but getting errors. I've read online that a good way to approach this is to migrate maps to a new project. The problem is people keep telling me that if I just migrate the maps I want it should move everything in use over, but when I open the new project after migration the maps are just empty. Anyone have an idea as to what I'm doing wrong here?

[maiden wadi]

What are the actual errors?

[iron idol]

Well the error itself is "unknown". But I think its because of me not knowing what I was doing when I started out. I added way too many assets and deleted a lot of them. I believe this is causing the error. But I would have a better Idea if I could figure whats wrong in my first message

[maiden wadi]

You should be able to get an output log of the packaging. If you can, post that in #packaging

[iron idol]

I appreciate it, but what I'm looking for at the moment is not packaging. I simply want to know why everyone is saying just migrate the maps and it will bring all depencies with it and mine are blank after migration

I would also like to just clean up my project

[maiden wadi]

Personally, I think migration is a bad idea. If you want to clean up your project, then do it. But even if you got the migration to work, the packaging issue probably still needs to be solved or you'll end up right back here just making a third project next time it happens.

[iron idol]

I understand, but I made a lot of mistakes early on and my project is flooded. I force deleted a lot of stuff and just made a lot of bad noob mistakes. I have so many assets that going through it manually would be a serious headache. So i was just hoping I could find a solution to the mentioned issue.

[junior prairie]

Is there a way I can more gracefully handle falling through the map? Right now there's a bug in my game where when my pawn dies, sometimes the camera falls through the map and after that point, I can't input anything anymore. Is there some sort of event I can use that gets triggered when someone falls through the map so that I can run some logic to reset them?

[iron idol]

I mean if your character is falling through the map, is there really a graceful way to handle that?

Its a bad answer, but I would probably start with figuring out why the character is falling through the map

[junior prairie]

lol, it's really just the camera that's for some reason falling through the map

the character ragdolls and collides with the floor as it should

[iron idol]

maybe check collision>

[junior prairie]

I saw that the camera has gravity enabled so I'm giving disabling that a try

[iron idol]

settings in the camera. and maybe character as well if the camera is attached

[junior prairie]

because why would the camera need gravity

[iron idol]

yea. wasn't meaning to come off as rude, but in my opinion at least, dealing with the problem would be the easier solution

[junior prairie]

yeah for sure

I was just wondering because it seems like falling through the map and into the infinite abyss causes the playercontroller to like

stop taking inputs

so i thought maybe it had some weird properties to it

[iron idol]

The closest I've gotten to this issue is purposely jumping off the map before immediately hitting escape in case UE magically explodes

I mean the other solution might be a damage volume under the level, depending on the level. But it shouldnt be too difficult to figure out a fix for the problem in general

or maybe just a trigger box

When your character dies and doesn't fall trhough the floor is input retained?

[junior prairie]

Yeah it is

Actually I think all it is is maybe the pawn getting destroyed prematurely, so none of my logic runs that would allow me to continue playing the game

because I realized I can still pause the game and stuff, so inputs are still possible

[iron idol]

that could be it

[junior prairie]

normally when the pawn dies, a bunch of stuff happens before the actor is destroyed

I don't know how I would work around that though other than just prevent the actor from being destroyed prematurely lol

[iron idol]

can you share the code?

[junior prairie]

Which code?

[iron idol]

the actor dying

and being destroyed

etc

[junior prairie]

Oh shit

[iron idol]

there it is haha

[junior prairie]

LOL

[iron idol]

yea

[junior prairie]

I haven't looked at this code in like over a year

I forget why I did this

I probably had a reason

[iron idol]

you wouldn't believe how many times I had a problem that I'm sure I cant fix, and right when I'm sharing it realize something isnt set up right

[junior prairie]

I maybe did it so when the pawn dies, it doesn't block other players' movement and stuff

in fact I think that's exactly why

[iron idol]

well, i'm glad you figured out the problem

[junior prairie]

yeah, thanks for your help!

[iron idol]

Does anyone know why deleting a bunch of assets increased my project size by like 10 gb? Does packaging increase your project size if it fails?

[junior prairie]

Don't know the exact answer but I do know packaging increases your project size by like a gazillion

and the files get created through the process even if it fails

Try deleting all the files that get created when packaging

[iron idol]

it doesnt clean up the files on failure?

where are these files

[junior prairie]

I don't think so

Are you packaging on windows?

[iron idol]

yea

i saw a build folder

[junior prairie]

There should be a Windows folder in your game directory

[iron idol]

is that it?

[junior prairie]

nosir

[iron idol]

well windows is under build

[junior prairie]

yeah not that one

should be in your main directory

It should be a folder called Windows that has an Engine folder, a folder named after your game, an .exe for your game, and then a bunch of txts

my directory looks like this

[iron idol]

are you talking about the packaged game?

[junior prairie]

Yeah, when I package my game for windows all the files go in the Windows directory

[iron idol]

yea i dont have any files

in the package destination folder nor the project folder

Oh well. I finally got it to package, so I'll leave ths file size problem for future steve.

[junior prairie]

New question, what's the best way to design a skill tree system? Mainly looking for it to be easily extendable/scalable

All I can think of right now is having a data table to store the information necessary for the widget like name, cost, description, etc.

[iron idol]

The question is a bit broad. there should be a lot of tutorials that will teach you skill tree systems.

at least i would hope so

[junior prairie]

Yeah I was just about to add some detail, it's for an RTS style system where you have units, and the skill tree might upgrade stats on individual units

I'm trying to brainstorm how I can set up the system such that it's not too hard to add new skills to the tree that modify the units

but am kind of coming up with not much

if I had a data table, one column could be the blueprint class of the unit the skill/upgrade pertains to

but I would need a way to track on the RTS player's pawn what upgrades they've unlocked and I'm not sure how to store that

[rugged wigeon]

GAS. Each skill unlock is just a gameplay effect

[iron idol]

I really should have learned to use GAS

[junior prairie]

I was afraid someone would say that

[iron idol]

honestly do it

my game is heavily ability oriented and i should have learned it

[junior prairie]

same...

[iron idol]

it probably would have saved me a lot of time

[junior prairie]

lol

[iron idol]

i'm too deep now to go back

[junior prairie]

I have no clue how it works other than this random youtube tutorial I watched that went over the basics

[iron idol]

I feel so dumb actually having to ask this, but how would you go about making a widget that is a specific size and the text box inside will adhere to the total widget size

if any of that word salad makes sense

[rugged wigeon]

Text boxes have min desired widths. Use that to determine the size of the widget

[junior prairie]

Scale box is good for scaling to the size of a parent

[iron idol]

Where is that in details? This is actually what I was looking for

you would think it would want to limit the max width. How do you achieve this with min width?

[rugged wigeon]

You tell it to wrap text

Min desired width is more useful because your text might not be long enough to justify the space you’re telling it to use

Well actually I don’t really get your question. Setting min width will make it that width

I guess yeah wrapping text will stop it from going bigger

[flat raft]

is it possible to add a data asset, or swap a data asset during run time ?

[lunar sleet]

Idk about creating one but wdym by swapping

[flat raft]

if i have a dataasset that describes how a gun should fire, and then mu character picks up a mod, i want to swap that exisiting datasset with the one that represents the mod.

[lunar sleet]

Well how are you loading the DA at runtime currently?

[flat raft]

say the gun initally holds 6 shots, then i add a different dataasset that says the gun can hold 8 shots

[flat raft]

this is my question... can I ?

right now i can add a asset before begining the game

but dont know if i can add or swap while the game is running

havn't tried it yet... but I assume "Construct Object from Class" ?

i'll try that 😄

[fiery moon]

If a property hold that data asset, cant you just assign a different one to that property?

[flat raft]

that's what i'm asking

but at runtime

[visual ember]

you need a reference to DA. you have a reference to one DA now. you need to swap it to another DA. don't think there's anything magical to happen beyond that

[random pulsar]

hey guys

[gentle urchin]

Imagine creating one DA per gun per mod. Doesnt sound all that scalable

[shrewd sorrel]

hey there is anyone able to help me implement the player not being able to do a certain mechanic when its not grounded

[random pulsar]

here is my character blueprint
i have a component that has an event for healing
it works fine with self reference or witcher reference
but how do i make them both the target?
i created an array variable of type character and wanted to select them in details pannel but i cant
why i cant and how can i make the idea i described?

[shrewd sorrel]

i can show the code if needed

[visual ember]

the whole point of this discord is that you post your issue with as much info as possible, then hope someone knows the answer and responds. so... just post your issue

[shrewd sorrel]

will do

im currently working on a third person souls like mythology game and ive implemented dashing but whenever the player jumps its able to dash in the air and i would like to only have it dash when on the ground and i dont know how to implement that into my dashing mechanic

[visual ember]

you have to have a reference to an actor. and you cannot point from one actor to another from within - this is just a stamp for making actors, no other actor exists yet at that point

[gentle urchin]

Make a function -> CanDash
Include !IsFalling in the check

[visual ember]

would have to add a reference manually to this array

or arrange array on the instance in the details after placing in world

[shrewd sorrel]

thank you am i able to use my isjumping reference as i do not have a isfalling

[gentle urchin]

You have isfalling

You're subclassing Character

Its either directly on char, or on the CMC

[shrewd sorrel]

oh okay

[visual ember]

CMC = CharacterMovementComponent 😉

[shrewd sorrel]

the Nav Movement Component??

like this?

[random pulsar]

like this?

[shrewd sorrel]

wait no its not thats from my anim_bp not for character movement

[visual ember]

sort of. just don't add it every time before wanting to heal. unless you clear it as well at some point

[shrewd sorrel]

what do i add to my candash function to make it work

[visual ember]

CanDash was supposed to be a helper function to wrap that logic as a named piece of logic.

Now for the actual issue, look what you tried to do. You tried to SET the value of IsFalling. Does that make sense?

[shrewd sorrel]

sort off

[visual ember]

no, it doesn't

you want to check if the character is falling

[shrewd sorrel]

how would i put a check out for that
