blueprint

[gentle urchin]

No

It stops the instant it hits the return

[faint pasture]

The first time it hits a return, it's done.

[naive stag]

They are in the same array, and I need to get the first item out of them

[faint pasture]

So what's the difference. What are you asking?

You want the first valid actor ref. You got it. What do you need now?

[sudden zephyr]

Thanks for the info. 🙂

[naive stag]

Alr welp there might be an error in my blueprint that caused it not to work

Im gonna try fixing my blueprint because the function seems to be working

[faint pasture]

Show what you have right now

[naive stag]

My whole blueprint?

[faint pasture]

Just the function

[naive stag]

I just used this one

I think it works

Im not sure

[teal talon]

Question: I can not get my brain around this, after days. I have a Widget in a BP. I can't figure out why I can't easily get the Widget to only control the BP it's in. I go around and around with Guides but I can't drag anything in to this widget target actor ref (actor object ref) like the guides do. Please help me get past this. Right now everything works fine when there is one of them. But it there are more than the widgets change the ones they aren't connected to. I don't know why casting is so hard for me to understand.

[gentle urchin]

Update the reference ?

This setup does seem a bit strange, does it not

Wouldnt you want the BP actor to handle the reaction from the widget interaction ?

so instead of inside the widget you try to cast to some bottle type

the bottle already creates the widget or what?

[teal talon]

the bottle and widget are both in the bp

[gentle urchin]

exactly

[teal talon]

widget has all the code

[gentle urchin]

well

I guess it's fine

[teal talon]

other than the change style to change the mesh

99% of the changes are in the widget

The issue is I can't get the widget it cast to the bottle it's connected to

[gentle urchin]

You can but this is part of my argument really

the bottle already know about the widget

it has no way not to know about it, as it's the owner of the widget in a way

while the widget doesnt really know about the bottle (unless you tell it about it)

[teal talon]

hmm ok,

[gentle urchin]

Wouldnt it then be cleaner with Event Dispatchers in the widget

that the BP can listen to?

[teal talon]

But the widget is listening for the clicks and hover events not the bp

Sure how do I do that

Sorry I'm new

[gentle urchin]

You'd make event Dispatchers equivalent to your function calls in the actor

So for example we got the "Change Style" function

which has an integer input

So in the widget you can make an Event Dispatcher "SetNewStyle" or smth, with an integer input

So the widget would look like this

Dispatchers can be listened to by others

so in this case i'd say the bottle should listen to the widgets dispatcher

and react to it

this can be setup like this in the BP_Master_Bottle

[oblique elm]

how do I detect if a player joins a match for the first time?

[gentle urchin]

prob by some unique ID that you store somewhere

[flat coral]

What's the best way for the parent actor to pass a function reference to an actor component?

Like I want the component to be able to call a function supplied by its owner (to get things like dynamic pickup text that knows how many of the thing you have)

[versed sun]

Get Parent Actor ?

[teal talon]

Why do I need to create it when it's already a component. I'm so new to this, it's much easier for me to not do any dynamic stuff and have everything as components. But when I try and drag Widget component in to bind the target I can't.

I really hate this part of the dev. This doesn't make sense why it's so hard to pass info back and forth, it's the entire point of interactions.

[hybrid latch]

Is it possible to Finterp to backwards / inverse? If not are there any alternatives without the use of a timeline?

[faint pasture]

Sure, just Finterp to a smaller number then you're at already

unless you're trying to FInterpFrom which is weird.

[hybrid latch]

Target is a smaller number than current.. Just jumps straight to target and doesnt interp anything

[faint pasture]

Show your code

[hybrid latch]

Think I might found the issue.. 2 sec 🤣

[gentle urchin]

Its not that hard once you know how to. But you usually dont wanna tie every class together when it doesnt make to much sense

[gentle urchin]

The target is not the component but the widget that the component holds

"Dynamic Widget" in your case

[teal talon]

yeah I can't get those to connect

[gentle urchin]

did you make the dispatcher in your widget blueprint?

[teal talon]

I think I did it correctly.

[gentle urchin]

Dynamic widget variable, which type is that?

[teal talon]

I just made a variable of the return value at first but then went back and did a widget object ref instead. What should it be

[gentle urchin]

Promote the return value to a variable

so its the specific class that you're using

Thats why it wont connect

it doesnt know that your reference is that specific class , and thus has the dispatcher that you're asking for it to bind to

[teal talon]

ok something like this

Since I already have the Widget class in the component doesn't create wi widget wine widget make a second 1?

[gentle urchin]

Yeah, i avoid the default one

Not very usefull in the first place cumbersome to get the widget ref from it

[teal talon]

but if I remove it I don't have anything in viewport to work with and move?

[hybrid latch]

Thought I found the mistake.. I did not. Probably my own stupidity getting the best at me but here goes..

[gentle urchin]

The component still exist. And we're adding the widget on beginplay

[hybrid latch]

Shouldnt this be looping?

[gentle urchin]

Instantly , yes

You wanna spread it acoss several frames

[teal talon]

But I need to design the widget around the object in the view port. Can I assign it at construction instead?

[gentle urchin]

Prob works fine on construct yes

The binding may or may not

Id set that up on beginplay regardless

[teal talon]

create widget can't be used in contruction is says.

hmm, maybe I'll remove whats in the component on build

[gentle urchin]

Theres always loopholes, but id suggest reconsidering

[spark steppe]

try it, either it works or not

[teal talon]

I'll see how it works, Regardless, I thank you for your time and efforts. This solved my issues and my bottles and interfaces are working correctly now. You are a superstar! Can I follow your youtube?

[spark steppe]

but for your final BP you shouldn't do it in construction

[hybrid latch]

this answer for me?

[gentle urchin]

I should've started one long time ago , but never got around to it lol

[gentle urchin]

Yes

[spark steppe]

if it won't let you do it at all in construction, you can cheat that thing by wrapping it in a function

[teal talon]

oh np, any other way I can support you

[gentle urchin]

Thats the loophole

[hybrid latch]

I dont understand why that should be instantly..

[teal talon]

oh interesting. At this point it doesn't seem like it's duplicating the widget.

[faint pasture]

Yeah the lerp should be hit on tick, not in a loop like that

it'll all resolve in ONE FRAME

so it'll be instant

[hybrid latch]

Works fine when it is not in reverse..

[gentle urchin]

Because it executes everything within one single frame

[hybrid latch]

other way around is the issue

[gentle urchin]

This will not work, forward nor backwards

[faint pasture]

That logic is totally screwed up. What are you trying to do?

[hybrid latch]

Works perfectly when lerping towards smaller FOV

[gentle urchin]

Then its not the same logic

[faint pasture]

That's a fortunate accident then. Do it like this
Set FOVTarget wherever

On Tick:
Lerp FOV towards FOVTarget
Detect some state (bIsFocusing?)

[spark steppe]

or just use a timeline

[gentle urchin]

If fov != fovTarget -> lerp

[faint pasture]

Lerp anyway

[gentle urchin]

Or that

Just lerp forever

Doesnt matter much

[hybrid latch]

No timeline cause in function..

forwards that works aces

[faint pasture]

Is that on tick?

[hybrid latch]

same function

Not on tick

[spark steppe]

because you aren't creating a loop that runs within one function call until it reached it's target (that's just the answer why #2 works and #1 not)

[faint pasture]

How TF does it lerp over time if it's a one time shot?

[gentle urchin]

Its called multiple times

It must be

[hybrid latch]

Fark.. I know. There is a timeline running before this function is called, ofcourse

[gentle urchin]

There we go

😄

[hybrid latch]

https://tenor.com/view/that70s-show-kitty-drinks-drinking-day-chill-gif-16669162

[gentle urchin]

Devils in the details

[faint pasture]

That's basically the same as a tick. It's basically a temporary tick. Either way, that's how lerp works. You update something a little bit every time.

[hybrid latch]

I know..

[lime yoke]

Hello guys, got a question. I want to make an Enemy Spawner (Let's call it BP_Spawner) and I'd like to make a Box Collision where I can select random points inside it. What I'd like to do is having the box collision as a different blueprint where it can contains it's own parameters, such as monster type, monster difficulty, and stuff like that. The reason why I'd like to have the box collision in a different blueprint is because that way the level designer can add more than one BoxCollision inside BP_Spawner instead of making tons of Childs from BP_Spawner that are going to be used only once. Problem is, the only blueprints I can attach inside an actor blueprint are Actor Components, and Scene Components, and none of those have a viewport. If you used unity before, I'm trying to make a GameObject and put it inside another GameObject.

[hybrid latch]

As I said.. My own stupidity got to me

[faint pasture]

Are you meaning to drive bIsFocusing by FOV or the other way around? is focusing the "zoomed in" state?

[hybrid latch]

Focusing is zoomed in yes... I think I have a easy solution now

[gentle urchin]

The spawner can have a public array of volumes

[faint pasture]

Have BaseSpawner at begin play make an array of all its BoxCollision components then iterate over them later.

Subclasses of BaseSpawner can add more volumes if wanted.

[gentle urchin]

More dynamic

Go public,

Bind to the events you need

You can make a separate box actor (and use that class in the public spawner array) with your own parameters and stuff

Would suffice for pokemon spawning

[faint pasture]

Is the box used for collision/overlap or just as a place to mark out where monsters come from?

[gentle urchin]

With non-rectangular areas

Or multiple areas in general

[spark steppe]

you are looking for the child actor component

[gentle urchin]

shivers

[lime yoke]

Just to mark where monsters are going to spawn. Each box collision should have properties to tell which type o monsters can or cannot be spawned. For example, if I have a tower, I'd put a box collision with the properties that only monsters of type ranged can be spawned.

[spark steppe]

even tho i don't think that this whole approach is saner than having multiple instances of the spawner

use a array of structs

and the struct defines your spawner properties

[gentle urchin]

If its hidden spawns like pokemon

[faint pasture]

But you want multiple boxes per spawner?

[gentle urchin]

Its prob not nvm

[lime yoke]

Yes.

I'll try to illustrate quickly in Unreal.

[spark steppe]

it's pretty clear imho

[faint pasture]

I get it, just trying to sort out how it'd be easier then just copy pasting a spawner around

[spark steppe]

but you are overengineering it

[faint pasture]

ballpark max how many boxes for a spawner?

[lime yoke]

I'll explain in a second why I can't put many spawners.

[spark steppe]

i'll explain in 2 seconds that you can

[faint pasture]

I would probably do it with 2 actors. One to designate areas, and another to do the spawning logic. Just plop the boxes all over the place, then have the other one get all actors of class at begin play and do all the spawning.

[spark steppe]

yea that sounds better, if you want to control spawn within the same actor

[faint pasture]

the actor doing the spawning could also just be a component on Gamemode or whatever but it's no biggie. That's how Epic does things (navmeshbounds volume, lightmassimportance volume, etc.

that way you can have some global parameters too (max monsters total, etc)

[spark steppe]

also you can edit them in the level

[faint pasture]

Hell even the Chaos solver is an actor I'm pretty sure.

You end up basically replacing what you're thinking of with box actors that spell out what can spawn there, and a global spawning actor.

[lime yoke]

In this scenario, the EnemySpawner is placed in the center of the room.
When the player enters a room, and overlaps the white box, this will work as a trigger and will close all the doors in that room. The player cannot exit the room until all enemies are defeated. In this room, the level designer decided that around the center, only Heavy Armor enemies are going to be spawned (Red Box), while in the rest of room on ground level (Green Box) only Medium Armor enemies can be spawned. There's also a high walls (Blue Box) where only enemies of type Ranged can spawn.

[spark steppe]

one manager with a bounding box, which encapsulateds the whole spawnarea that he should control

3 actors with the spawn settings

[lime yoke]

In order to have a tool easy to use for the level designer, I wanted to know if was possible to use an Enemy Spawner, and be able to add a component like this, where I can make multiple box collisions, each with their own properties.

[spark steppe]

manager gets it's overlapping actors and manages spawns

that way you can also handle intersections

[lime yoke]

I see, I suppose that's a way to do that.

Thank you for the help, guys. I really appreciate it!

[teal talon]

Now that I have this working, I've been struggling to decide where to store the Collectables Unlocked Data, do you have a suggestion of a easy way to store basic RPG style data like this?

[serene bramble]

How hard would it be to make some kind of "wind noise" that plays? I don't want or need actual wind so not buying anything to do it; I just want some gust sounds playing while outside, and for them to stop or maybe dull down when inside

[faint pasture]

Starter content has a cue with that.

[calm cargo]

How can I obtain the biggest float (the limit) value?

[solid zenith]

How could I check how long key was held down last time? Get Input key down resets to 0 before check comes through can I store it somehow and reset only after its pressed again?

[calm cargo]

Oh, do I have to type it in manually?

[soft plinth]

try

[icy dragon]

Depends on how much fractional precision you want to have

[calm cargo]

Anything close enough would do I suppose

I was hoping for a predefined thing, I suppose I can make a re-usable BPFL for those but it wouldn't be as future proofed

[astral fiber]

Is this the preferred way to iterate trough a map?

[sudden nimbus]

I've not seen better, but you usually can safely skip the branch assuming you aren't in an event context and using delays (and thus the list can change underneath you)

it's definitely safest to keep it though

Ive thought about making a macro for this assuming I've not totally missed a built in one

[cyan bone]

Im animating my material up and down. Now Im trying to stop animation of just one instance. So i use Set Custom Data Value. But its not working. What am i doing wrong?

the return value prints false

Okay i found out the problem

[sudden nimbus]

There is only one path that returns false, the conditions are pretty easy to understand.

[cyan bone]

Its because its dynamically added. It needs Num data custom floats.

[vast widget]

@lean summit if you're on PC, hit ctrl + r that'll reload discord

[lean summit]

Anyone see why this would only set the Pressed icon? Hover and Default still show the original icon when I call this on my button on press, but Pressed works.

[lean summit]

worked thanks

[cyan bone]

thank you @sudden nimbus

[sudden nimbus]

because you are always first setting it to Normal, then Hover, then Pressed no matter what

[lean summit]

Explain, I'm trying to set the Image for all 3 states, I'm not setting the state to anything

[sudden nimbus]

You are setting it to all three, in sequence. You only see Pressed, because thats the last one

if you changed the order, whatever was last would be the one you saw

you need some kind of conditional here

[lean summit]

Changed the order and it's the same, no change in behavior

This code isn't setting the button to pressed hovered or default and it's not supposed to

[sudden nimbus]

I don't think you changed the order I meant

What did you change it to, curious?

[lean summit]

It's setting the icon on all 3 structs

[sudden nimbus]

Ohhhhh

[lean summit]

I changed the order of the states being changed from default->hovered->pressed to hovered->pressed->icon and obviously no change because that's not what this is supposed to do

[sudden nimbus]

Yeah I see now

Well I wonder if its using one of these other styles for Hover/Normal

i know little about slate 🤷‍♂️

there is a dedicated #slate channel

[cyan bone]

I was told here that Material animation is cheaper than vinterping instances. So is material animation more performant than any type of animation?

[lean summit]

I know little about slate either unfortunately :( Normally at work I literally never leave visual studio but the last couple days I've had to extend UMG into a full UI framework with data views and toolbars and dialogs and whatnot and it's been very, very frustrating

[sudden nimbus]

oh my

i dont envy that

[lean summit]

Like it works and it's fine it's just a game of constantly fighting against whatever UMG wants to do and then wanting to do a belly flop off my balcony when it fights back

[sudden nimbus]

"more performant" is simplifying it a lot. When you animate in a material you are shifting the compute involved in the animation from the CPU to the GPU. However, if you are passing the animated values in from a blueprint or C++ you are not shifting that compute to the GPU. In that case, the cases where you'll have appreciably better performance by animating that material (ie using a custom parameter) are much more narrow. It may be faster, but you wouldn't want to do it by default over using a simpler path, especially if you don't have a performance bottleneck you are trying to solve

[sudden nimbus]

if you havent dug into input handling for this prepare for more pain to come

When you animate in a material you are shifting the compute involved in the animation from the CPU to the GPU.
This can be a bad thing too. Your GPU, while being powerful, is limited. If you need to be "highly scalable", meaning you need to support a wide range of GPUs from "bad to amazing", then over-reliance on animation directly within materials at scale (meaning lots and lots of instances of these actors etc) could even perform worse, depending on the hardware

The GPU still has to render everything after all

not just do animations

[lean summit]

Fixed it by just switching out the button... lol it isn't great but it'll do

[sudden nimbus]

first hack of many im sure hehehe

[lean summit]

Manyth hack of many

I usually take pride in the fact that I work nights just to clean up the codebase fairly often and hold a pretty high standard for no hacks when reviewing code

But this entire UI framework on top of a game hud UI framework on top of a UI framework is a hack

[sudden nimbus]

is it a hack if its packaged nicely into a custom button or component or whatever? ehhh

if it works for the budget....

[lean summit]

lol, i guess as long as you never have to interact with the hack underneath, it's not a hack

[sudden nimbus]

thats right, until someone wants a (conditional) halo around that sucker

but i do recommend #umg and #slate as you continue that project

way more specialized advice in there

even if it might take a bit longer

[lean summit]

Long term I want to build out a way to render Qt widgets within Unreal, or better, Unreal viewport as a Qt widget, because for what I'm actually doing that's probably the best choice of tools overall, but this is the way right now and I will satisfy it until my boss approves putting more resources on this for full production

[sudden zephyr]

So probably a weird question but I have some child actor that relies on parent actor (for bone placements) and I was wondering if there's a way to actually apply/see the animBP results in the actor BP itself?

[sudden nimbus]

this is doable using render targets and some c++ glue

or possibly handing unreal a hwnd or so but no guarantees

just can't ship with the editor code though but yeah I'm sure you know the license

[cyan bone]

Sorry i dont know if i understood well. So basically material animation can be more performant if not done by passing the values ? You mean passing the values like when you activate the animation in a blueprint as opposed to ?
This is what im doing ^^^ . Just a loop that tells material "Hey its on". Now the material will just move up and down. So its passing the value just one time? Isnt this super performant/cheap/awesome? Or i was fine just vinterping all instances all day?

[sudden nimbus]

if you set it only one time, yeah thats approximately as good as not passing anything from the CPU

seems like itd be fine, but I assume youll then start adding more capabilities to these soldiers

One thing you might consider is collision-- are you intending the soldiers to have collision? If so WPO isnt going to translate to that

[cyan bone]

well observed. the collision is treated in a different way, by batallion, not by individual instance. Individual instances dont have any collision (to be cheap 🙂 ). However this animation is just a smooth hopping, to simulate the soldiers are walking

[sudden nimbus]

ahhh ok

So there's going to be a lot of these I'm guessing

Also sounds like you already were vinterping and had performance issues

which wouldnt be surprising if you were vinterping on tick for each one or so

[cyan bone]

No i didnt have issues with vinterping. I was just old "hey dont do this, do that, is more performant". So now im doing this 🙂

[sudden nimbus]

That's fair, and if you just want to animate them up and down in a walk, its a fine way to do it especially if collision or other factors are handled externally

I think your current path sounds fine- but since the GPU is a limited resource, its not like material animation with WPO is a silver bullet that should just be used for all types of animations

Everything has tradeoffs 🙂

[limpid bronze]

Where do I go to ask a navigation mesh question?

[cyan bone]

ok i will keep the old lerp function. So just in case, later on when i test a big battle,
and there are issues, i try the lerp. Thank you @sudden nimbus

[sudden nimbus]

#gameplay-ai 😍

[grave apex]

does anyone know how to locate what specific print function is printing a string during runtime?

[twilit heath]

its also printing into your output log, but with source blueprint mentioned

[grave apex]

ah, im seeing some of them here

is there a way to jump to the specific node?

from here?

[sudden nimbus]

nope

and it's not always exactly right, but at least it's something

[solid zenith]

Sorry but how does introducing delay node here creates infinite loop

actually I remember now something in unity c# called coroutine cause you couldnt delay in any loops due to some reason if this is the same issue what can I change this into, press button > set float to 1 > immediately start reducing float until it reaches 0

[thin panther]

while loops need to execute in 1 frame in bp

when they dont do that it throws infinite loop error

one of the advantages of c++ is this doesnt happen

[sudden nimbus]

think of it like it just continues while the delay is waiting to continue execution

[thin panther]

^

what you want is a timer, or a tick event

looping timer, increase the index you look at each time

[sudden nimbus]

while loops need to execute in 1 frame in bp
btw its so much worse than that (i mean bp's so called "infinite loop" detection)

[solid zenith]

I use couple of them was looking for better solution

cause thats a lot of stuff to do for something like this idk

[thin panther]

that is a better solution

[solid zenith]

if timer is best solution thats disappointing lol

[thin panther]

if the correct way of doing things is disappointing then idk what to tell you

especially seing as delays arent great in the first place

[sudden nimbus]

why wouldnt you delay the whole loop

[thin panther]

frame rate dependant, if you want time based things, use the time based methods

[sudden nimbus]

it would be the same

[solid zenith]

you mean put delay before loop node?

[sudden nimbus]

uh huh

[solid zenith]

what the hell does that even mean

[thin panther]

the correct implementation here would be to move to a timer or something

if thats disappointing then idk

[solid zenith]

ya and I said thats a lot of work for simple thing like this

and that was my disappointing part

[sudden nimbus]

a timer might make more sense, i cant tell from the screenshot i guess

[solid zenith]

not the oh no! correct solution! how disappointing

[thin panther]

ah

[solid zenith]

I will move to timer thanks

[thin panther]

timers workflow aint that bad when ya get used to it ;)

if your delay is gonan be really small like .01 then just go for tick

otherwise timer

[sudden nimbus]

i guess you want it to be delay 0.2 + another delay 0.2 + another delay 0.2 and yeah timers

or delay + invoke an event and take an item off of an array (pop) with a recursive event

either way youll need state so

but at least the delay + invoke an event recursively would not require ending the timer

[dusk cave]

I need help figuring out how to get my animations to work again after repossessing the character.

It was working until I added widgets for some reason

[sudden nimbus]

if you save the controller in your anim blueprint and don't deal with it changing, that would do it

widgets are highly unlikely to matter but you can write any code you want so not ruling it out

[summer pewter]

hey guys i have a set of weapons that all inherit from the same class. they all scale damage with the player speed. it all works fine except on one of the child classes. nothing except the values are changed between classes - they all share the same logic. i have a Base Damage and Max Damage value. it works on all of the child actors except the SMG which lerps from the Base Damage variable down to 0, instead of Base Damage to Max Damage. this is making my head hurt

[sudden nimbus]

ue4 or ue5

[summer pewter]

ue5

[sudden nimbus]

imported from ue4 or ue5 native

[summer pewter]

ue4 native to the EA to 5.0.1

sorry no

this code was redone in 5

[sudden nimbus]

any c++ in there? maybe a c++ base class for the weapon?

[summer pewter]

no just BP

[sudden nimbus]

ok

it's the SMG that doesn't work? because sounds like that does add new code, it's not just class defaults changing

[summer pewter]

that's what i thought, but it just uses inherited events and functions that all call back to the base class

[sudden nimbus]

is the damage applied zero or just not scaled to speed

[summer pewter]

it is scaled to speed but improperly. as i get faster it gets closer to 0, instead of closer to the max dmg variable

[sudden nimbus]

show the blueprint for the smg where it scales the damage

[summer pewter]

this function is called on tick on the player character and is part of the weapon parent class

[sudden nimbus]

what's the SMG specific code?

[summer pewter]

this is all there is

all the parent call on the begin and end fire do is just set a boolean

[sudden nimbus]

except the SMG which lerps from the Base Damage variable down to 0, instead of Base Damage to Max Damage. this is making my head hurt

so I guess you set max damage to zero then?

[candid geyser]

Quick Question: Can I make it so I can set something to decrease a certain amount per second?

(Not using a timeline specifically)

[sudden nimbus]

in blueprint? only by decreasing it yourself using a timer or on tick

[summer pewter]

you can set a timer for an event or function that calls every second to decrease a value by a certain amount

[candid geyser]

Ahhhh well I guess ill have to work with timelines

[dusk cave]

how do i save the controller in the anim bp?

oh never mind im dumb

[sudden nimbus]

I meant that having it not work anymore would result because you've saved the controller, the fix is to make sure that saved controller gets updated on repossession

[candid geyser]

The problem is that im trying to set up a stamina system, with a default value of 100, that decreases by 20 every second

That would be easy to accomplish with a timeline if it wasn't going to be possible to raise your max stamina

[sudden nimbus]

don't just fetch it every time either

that's a no no

I think it will even yell at you

[summer pewter]

something like this might work

[candid geyser]

Here's hoping! Thank you in advance

[sudden nimbus]

so where is the reverse behavior for SMG where it goes to zero instead of ramping up to max damage

[quick ember]

Hey everyone! I am working on a game and I need my character to grind on railings like this one https://youtu.be/yjKJ_oUMQ4Q?t=7 I am creating in Unreal Engine 5. If anyone knows how to create this please help me out.

[dusk cave]

im still confused so how do i get the animations to play on that controller

[sudden nimbus]

big enough and broad enough of a question to be actual work, see the hiring channels

[candid geyser]

Also. Has anyone found a fix for the flickering screen? When right clicking I mean

Bringing up any menu eventually just causes it to flicker and disappear

[sudden nimbus]

the animations don't play on a controller, they play in response to the controllers state

[candid geyser]

And then I have to restart UE4 to fix it

[sudden nimbus]

the way you feed that state into the animations is via the Update Animation node in the event graph of the character's animation blueprint

If the animation blueprint fetches the controller and saves it to a variable in Init Animation event or whatever, then it's not going to be right if you repossess

it would need to be updated whenever the controller changes

I'm pretty sure the stock content does this sort of stuff

[summer pewter]

that is what i was wondering also

i should be able to figure it out

[sudden nimbus]

maybe a quick video of that might help to know what it might be

[half portal]

how can I make it to dash in the direction player is moving in

[summer pewter]

override the xyz on both i think

[candid geyser]

I already restarted UE4 so ill just try to explain it best I can until it happens again

[half portal]

sadly didnt work

[summer pewter]

and also try using Get Actor Forward Vector

instead of rotation to get forward vector. might be the same thing but the latter always worked for me

[half portal]

Should have mentioned tho, my character often moves opposite where they are facing so the direction they are facing doesnt equal the direction they are travelling

[candid geyser]

After a while of using UE4, I could be in a blueprint for example, and right click to create a custom event, but after a while, the menu will immediately close after opening. I can still use the menu, and even click stuff, I just can't see it

[half portal]

didnt work :/

[summer pewter]

hmm. not sure sorry

[candid geyser]

So if I wanted to create a new action for the blueprint, I would just have to guess and hope I typed it in right

Same happens when dragging out a variable, the Get and Set Variable flicker away, but I still click on them

[half portal]

I have that exact same issue

The way I deal with it is save all when closing and restart

[candid geyser]

Same here

I just wish I didnt have to do that

[half portal]

Tell me more about ahhaa, had it for ages

Its not a blueprint issue tho, smth with engine and the pc system

[candid geyser]

I looked it up a while back and I heard it's apparently something with Nvidia drivers

[dusk cave]

okay ive been trying to update the variable to the controller but its not working

[sudden nimbus]

what hardware? (for the flickering menus)

[half portal]

heard that as well, some mysterious unreal forums user knew exactly what the issue was, but never got a reply when asked for a solution lol

[dusk cave]

no i mean the player controller

[sudden nimbus]

sorry meridian, other Convo

[dusk cave]

oh sorry i thought u meant me

[half portal]

[dusk cave]

This works when I press play but not after I try to repossess the character

[candid geyser]

Hey, is there a reason the Exec for Set Time has nothing connected to it?

Wait nvm I have an idea

[summer pewter]

because idk what event you have to set it up

[candid geyser]

Okay, was just making sure

[summer pewter]

cool

[candid geyser]

I wasnt sure if I should have left it blank or not haha

Okay! Did a little adjusting and its working!

[graceful sparrow]

How would I go about detecting floor using a line trace? I'm trying to prevent spamming the "launch character" action when falling
I did try checking with "is falling" and a "do once" but after doing the attack when jumping then falling and landing I can never do it again

Line trace at the moment stretches all the way to the floor and i'm wondering if i'm able to limit how far it goes

Main goal right now is to only allow launching in the air once until you land/touch ground, and is there a way to prevent speed stacking while using launch? Because right now I have a button based jump (like marios) and the amount of height you get from the launch changes a lot sometimes it will be a short launch and sometimes you just get launched to a huge height depending on the button press

[dusk cave]

you would limit how far it goes by changing the End Vector

[icy dragon]

Try disable window animation in Editor Preferences

[candid geyser]

Already off

[dusk cave]

if anyone can help me figure out how to get my animation bp to detect the player controller after repossessing my player, that'll be great 😦 about to get off

[dusk cave]

I don't think getting the controller is the issue because my player can move its just the animations not playing

This is inside my first state

[limpid bronze]

How do I set the game instance of my project?

[sharp fox]

Where i can post a world/material question

[icy dragon]

Project Settings -> Maps & Modes -> Game Instance Class

[wicked osprey]

I mean, if static mesh was not a root component and simulated physics, then the root component in the world would remain in one place

Yes, but I cant rotate it in BP class

[foggy escarp]

What is the problem? You can rotate and move bp actors in many ways.
Yes, if your root mesh is the default scene root and you have a static mesh component, the actor would stay in place. To prevent this just drag it into the root mesh to make it the new root.

But you could have always moved the static mesh component instead depending on your use case...

[gentle urchin]

If the mesh is the root mesh, its just about setting the world transform of the actor

if you need a new root, do as stinger suggest, and fix that

[foggy escarp]

I think the issue was its simulating physics and not root

[gentle urchin]

rip

i hate physics 😄

#legacy-physics #chaos-physics i guess

[foggy escarp]

Gotta embrace the jank

[wicked osprey]

I also told you that if I simulate the physics of mesh, then the scene root component will remain in place in space and if I want to save the actor location, then it will not save the mesh location, but the root component location

And if I make static mesh root
the root component, then I will not be able to change its rotation through the properties in the editor?

[foggy escarp]

That's not true

[topaz escarp]

Excuse me, I've got a project with an animation blueprint with a good few ik features in it. But, everything's based around the hand_r, I was wondering if it would be possible to hire a freelancer to change it to make the root the ik_hand_gun, as I haven't really found any tutorials or methods on how to actually use the ik_hand_gun in animation blueprints, especially in conjunction with ik.

[wicked osprey]

If I have such a hierarchy, then when simulating the physics of the static mesh, the acene root component will be in place

[foggy escarp]

you will have to make the mesh the scene root

[bronze hill]

If i set Input in character and place two instance on level and i possess one of them, then how input work? both them follow my input?

[wicked osprey]

But how will I rotate it in the mesh properties?

[foggy escarp]

Just give it a try, it will work

[wicked osprey]

If only through the code

[foggy escarp]

So you want to rotate in blueprints?

[wicked osprey]

Yes

[foggy escarp]

after setting the mesh as the new root, you can use the node for setting or adding actor rotation.

[bronze hill]

it will work, doesn't?

[candid geyser]

Okay, I have everything working as I want it to, is there a way I can take a box trigger and tell it to increase a float variable by a certain amount?

[gentle urchin]

sure

[candid geyser]

By that I mean increase a float that is in a different blueprint

[gentle urchin]

OnOverlap or whatever -> Other Actor -> Cast to myActor -> call the "increase float function"

[bronze hill]

maybe through interface?

[candid geyser]

I'll try this!

[wicked osprey]

Then you will have to do set rotation on construction script.

[gentle urchin]

i'd make sure its a function for it, so you dont go around messing with other bp's variables directly

[foggy escarp]

Why would that be?

[wicked osprey]

It turns out in my case only this way. I thought there was another method, but thanks anyway

[candid geyser]

Right!

[bronze hill]

I am confused about where to process the input. i can place input both playercontroller and character

[gentle urchin]

and in other actors too!

Be carefull tho,

it easily gets messy

[bronze hill]

yes that make me much more confusing

i place input all over actors

[gentle urchin]

there are many ways to do things with this level of freedom

I would try to limit the inputs to few actors/characters

[bronze hill]

i can move other actors unless i'm not possess that

[candid geyser]

Okay, so, when casting to my actor, it's asking for an object. Suggestions?

[gentle urchin]

"Other Actor" from the overlap event

assuming thats the event you went for

[bronze hill]

then what is th point of possessing?

[gentle urchin]

you can possess pawns, which are your main class for player representation

you can temporarily bypass the pawns inputs in another object if you wish to say.. open a door

Or you can use an interface for the interaction between the pawn and the object. In such case the pawn still handles the input, but calls an event on some "targetInteractable"

[bronze hill]

Thank you for explaining. I'll try to understand the subtle differences.

[candid geyser]

I think im blind or something, I can't find the increase float function

[bronze hill]

I know how to do it, but it's hard to understand the concept that Unreal intends.

[gentle urchin]

drag out from the "casted" actor reference, and search for it

if its not there, the method is either not public, or you're in the wrong class^^

[bronze hill]

you can simple create add float function using add float node

i think add float node itself is function

maybe not

[gentle urchin]

you usually dont want to manipulate other objects variables from externally, directly

[candid geyser]

Im trying to make so overlapping with a box trigger will change a float variable, but the variable is in a character blueprint

Im definitely doing something wrong

[candid geyser]

Thank you :')

I got it now!

And it's working!

[gentle urchin]

Ofcourse 😄

[bronze hill]

get playercontroller index 0 always mean myself?

[gentle urchin]

yes, the local playercontroller

if you're doing splitscreen, it gets worse

[candid geyser]

Hmmm, could I by chance make it so that the box can trigger more than once?

[bronze hill]

i'm studying multiplay, it also confusing😅

[gentle urchin]

like, tick over duration?

[candid geyser]

As in if you overlap with it again, it triggers again

[gentle urchin]

There's nothing blocking this from triggering again

[candid geyser]

Oh then time to bug fix B)

[gentle urchin]

show code 😄

[candid geyser]

Oh never mind it works!

Im just really tired and wasnt paying attention I guess

[gentle urchin]

Ah 😛

[hot lotus]

• Calling it on the Listen-Server will return the Listen-Server's PlayerController
• Calling it on a Client will return the Client's PlayerController
• Calling it on a Dedicated Server will return the first Client's PlayerController

[bronze hill]

Very Clear Thank you!

[hot lotus]

I suggest you the eXi compendium on unreal multiplayer. Some slides on the general concepts!

[gentle urchin]

That one is great

[icy dragon]

There's also that one YouTube video that goes into Unreal's networking system

Had pretty good explanation

[bronze hill]

thank you very much i will check right away!

[gentle urchin]

I have a little brainblock about a datatable setup. Imagine theres a specific shoe there with a specific UIC for that shoe in that size and color. In my scene i want to be able to have this shoe, and be able to switch the color and size of it. This would mean i need some way to reference the new rows with the new specific shoe with the color and size selected...

[bronze hill]

actually i usally study through youtube haha

[gentle urchin]

Sounds incredibly troublesome to add the relative row name for each possible combination?

Perhaps i could manage with only 4 links, (color up, color down, size up, size down) but then id block myself from keyboard input for the sizes or mouse input for the colors

Any suggestion for a better setup? This feels like a dumb one :p

Guess i could ass a second identifier, only used to identify shoes that are the same but a variation... then i could loop the datatable(or have a linker) that puts this all together...

I think that'll work!

Two DTs essentially

[icy dragon]

Ah, found it

[trim matrix]

Hi folks, anyone experiencing problems with boolean operators not working in ue5 animBP? I've had == returning false when 2==2 or a couple of true in AND returning false. Same strange behaviour with OR. And I could not find a way around it.

[worthy carbon]

hi! i'm using ue5 but how to let everything looks realistic?

[gentle urchin]

This check would be more suitable in the pawn that runs this , and just give a bool for the animBP to read

[minor thicket]

So is this a known issue? Im using a OnMouseButtonDown override event for a ui button but there is this weird input delay

[gentle urchin]

Turn on lunen, nanite, download a bunch of ultra realistic assets, place them in the scene, and whatch your gpu burn

[gentle urchin]

Overriding button down on a button handler?

Are you overriding on mousebutton down when clicking a umg button?

[minor thicket]

yes im overriding when the right mouse button is down

[gentle urchin]

How long is the delay?

[minor thicket]

and just a weird delay. like once i click it it wont run the override again for about 500ms unless i spam it

super bizarre

[gentle urchin]

Could it be trying for doubleclick

[minor thicket]

im thinking it might have to do with the actual check for the function is mouse button down

[gentle urchin]

Check doubleclick first

0.2 sec is the default value for it

[minor thicket]

no not double click

i changed the value to 0 and no change

[gentle urchin]

Is the button getting the click?

[minor thicket]

yes its getting the click

[gentle urchin]

Theres very varying experiences with override + button

I dont believe they're intended used together

[minor thicket]

but i have a ui to select spells and have to use a mousebuttondown override event to use right click. it works but there is a delay before it will run again. if i rapid click twice it will only go through once. if i spam it, it will run with less of a delay

you cant use right click with on clicked can you?

[gentle urchin]

How about ditching the button

And doing your own click handling in a new spellwidget?

[minor thicket]

well the button is created with each item added to the array i have. the plan was for left click to equip/unequip a spell to my left hand and right click to equip/unequip a spell to my right hand but the delay with right click really bugs me

[gentle urchin]

Overrides+ ubuttons always bugged me 🤣

[minor thicket]

this is what the event graph looks like

even with just this there is still a delay

[gentle urchin]

Test it

Without the button

And see 😄

Add a new temp widget , sizebox + border/image

And override click

Print

[minor thicket]

idk why there isnt a on right click event for buttons. or even just a click event that allows you to set which input will prompt it

yeah ill try that and see if theres still a delay

[gentle urchin]

Its an ancient button :p

Pre-historic

[twin pine]

I have an actor variable in my blueprint but I can't set a default value. It only allows me to set the variable with actors in the same scene. I'm guessing it's because on of these?

[gentle urchin]

If its a reference it must exist before you can set it

You cant set a default value to a ref

You could let this class spawn a new class and update the var that way tho

[twin pine]

It seems easier to just do this in c++

[gentle urchin]

Afaik you cant set a default value there either

[twin pine]

But I've managed to do this before in c++ by just adjusting the UPROPERTY

[gentle urchin]

If you say so

[twin pine]

and then set the default in blueprint

But I might be mistaken

[gentle urchin]

Pretty sure you are :p

But i wont bet on it 😅

I dont have a full grasp of all the c++ powers there are

Usually you just link these up at runtime tho

[twin pine]

Because this works( tho it is a niagara system and not an actor)

[gentle urchin]

Ye, not an actor

[twin pine]

yeee no I was mistaken

I'll just have to use the stuff in the scene

[gentle urchin]

You prob have to spawn the item again before using it :)

[pale blade]

Let's say you have an attack animation for one character
Is it better to play particle effects and sound via BP when the character attacks? Or is it better to add it in the animation notify?

[gentle urchin]

Anim notify sounds more natural

[pale blade]

When is the case you should add sound effects and VFX in anim notify? What case would be better via BP?
Assuming relating for things regarding animations

[trim matrix]

Wat's the difference between tick space geometry and cached geometry? seems like cached used tick as well?

[gentle urchin]

Very few, if any, imo. AnimBP is also just a bp tho

[trim matrix]

Anim notify sounds more natural, afterall for every swing you want to play a sound

[gentle urchin]

Its just... for me atleast it makes sense for animation related things to happen in the animationBP

[maiden wadi]

You may have better luck in #packaging with this. Launch being similar to packaging with a few small differences. Haven't had that problem myself, but I use Niagara a lot, so no intention to disable it 😄

[round basin]

Yeah that's right, thanks!

[strange blaze]

Hey I need help with something, I need to make a gate with 4 inputs, how do I make it so it fires only if 3 or 4 of them are active?

[trim matrix]

a gate with 4 inputs? wdym

can you post screen shoot of your bp

[maiden wadi]

Generally you just save state for it. A gate is nothing more than a branch with an internal boolean.

[gentle urchin]

Just check 3-4 bools for it

[strange blaze]

Hm okay ty

[gentle urchin]

Or state, as suggested

[trim matrix]

I don't know how others would tackle it, and I don;t know what you mean by gates that takes 4 inputs, You mean 4 different events going into the gate?

For the condition, I would make an array of boolean then do a for loop check to get the number of True bool. Then you can just do if statement if it's bigger than 3

[maiden wadi]

Well, bools are state too. 😄 Depends on if you need specific keys to be known.

If you need to know that key3 is active and key 2 is not. Then multiple bools, maybe an array of them for extensibility. Else you can just do an integer check.

[gentle urchin]

Int check ftw

Inc/decrement int on keypress 😄

[minor thicket]

okay after some testing on a new widget. still same issue

[gentle urchin]

Dang

Thats unfortunate

[trim matrix]

@minor thicket Why not try Listen for Input action?

[minor thicket]

I dont get it. It seems to be a problem with override

[trim matrix]

You are just trying to detect right mouse button?

[minor thicket]

when its over the widget yes

[potent laurel]

There is an override function for that no?

[trim matrix]

oh nvm

[gentle urchin]

Apparently slow

Like half a sec delayed

[potent laurel]

On hovered

[minor thicket]

i have an override but there is a input delay

[potent laurel]

Hmm

Weird

Is the widget that you are hitting at the front in "Z order"

Not sure why there is a delay

[trim matrix]

Try widget reflector to see if u are hitting the right widget (making sure no overlap)

no idea how to right click detection when hovering a widgeet tho

[minor thicket]

i havent messed with the Z order on it at all.

but i make a temp widget with only an image to test if there was still a delay on override and there was

[potent laurel]

Strange

[minor thicket]

it works perfectly but the delay makes it not really worth it

[potent laurel]

Are you using a print string on the right clicked event or whatever you are using

Could you provide some screenshots

[minor thicket]

if i spam it, itll run more frequently. like every .1-.2 seconds

yeah i threw up some screenshots a little bit ago but ill repost them

[trim matrix]

Someone did that

[potent laurel]

A default delay function is 0.2 seconds

[gentle urchin]

Theres also preview down etc

But not sure it helps

[potent laurel]

Must just be how the engine handles entering a widget

You might struggle with this

[gentle urchin]

The new widget you tested, there was no button there, right?

[minor thicket]

yeah im thinking the engine might have a delay or something for when the mouse button is no longer down

yeah the new widget was just an image

and same response

[gentle urchin]

Let me test

using a random widget and the override

[trim matrix]

Im testing it right now

if u right click once it's fine

but if u spam it

u can notice the delay

[minor thicket]

strange

[trim matrix]

Hmm lets find other solution?

dont use that function

[maiden wadi]

It's not a delay

Double click.

[trim matrix]

Well it doesn;t fire the print string

yeah maybe it;s trying to detect double click?

[minor thicket]

i set double click value to 0 and it was still the same

[maiden wadi]

Make a function that takes the same parameters as on mouse down. Call it in both OnMouseDown and OnDoubleClick.

[gentle urchin]

its the doubleclick

so as Authaer suggest

[trim matrix]

How to detect double click? can u share ur bp plss

[trim matrix]

Thank you

[gentle urchin]

Its just an override

just call the very same function with both overrides

"tryExecuteSpell" or whatever 😄

[trim matrix]

@minor thicket Yo they find tthe problem 😄

[maiden wadi]

Have had that problem in a few widgets. Very annoying that it's not easily disabled. But the override calling same function is at least easy.

[gentle urchin]

the double click also relies on being the same button twice

so if you do LMB, RMB, you can click like a hero with only single clicks

[minor thicket]

thats so weird that its automatically detecting double click

[trim matrix]

The function is always there

u are just overriding it

[gentle urchin]

the backside of the coin of convenience i guess

its a nice override to have, imo

but feels a bit backward when you dont need it, I agree

could easily be some config for this

[maiden wadi]

Imagine everyone starting timers everywhere in widgets for double clicks. 😄

[trim matrix]

I think Im using gate for double tap action

copied sum1 bp

not sure if that's proper

[gentle urchin]

Im using delays for double clicks

or i was, anyways

[trim matrix]

yea gate and retrigable delay

FF9 is sick btw

[maiden wadi]

I use GetRealTime comparisons with saved floats for it. But only in gameplay actors. In UI it's always double click overrides.

[trim matrix]

They do FF7 rmk, but i doubt they will do 8 rmk, maybe skip to 9

[gentle urchin]

would be nice

then I could die happy

altho, 9 is a gem as it is aswell so guess i shouldnt complain

[trim matrix]

7 is the best for me but i love 9, it has different aestetic

[gentle urchin]

was a shame that they lost the original bg's tho

[trim matrix]

I stop playing FF 10 onwards

7 - 8 - 9 is what i long for

[gentle urchin]

This might be the more proper way really

I dont like double click/tap functionality tho, since you have to block/delay the single click

[minor thicket]

okay so at least now i know and ill be able to find a way around this lol. probably just find a way without using an override

[trim matrix]

Nothing wrong with override anyway?

[gentle urchin]

just override both

[trim matrix]

just my 2 cent

[minor thicket]

yeah ill do that first and see how i like it

[gentle urchin]

They're the best ones for sure. I did enjoy 10 aswell, but after that it got meh

[trim matrix]

didn't expect them to ditch their engine for UE4 lol

[gentle urchin]

well, ue4/ue5 is coming up great imo 😄

[icy dragon]

Luminous is great, but more people use UE4/UE5

[minor thicket]

works perfectly. had to fix how i had it set up for unequipping spells, but that wasn't because of the override lol

[trim matrix]

Am i doing something wrong?

[gentle urchin]

Seems reasonable i guess ?

[trim matrix]

what?

[gentle urchin]

The setup, nothing obviously wrong to me there

Sure id stuff it in functions etc but thats just cleanup

[trim matrix]

But it doesnt save

[versed sun]

maybe set Save SubClass after you cast, and make sure its type SGBasic

and make sure your folder your saving to isnt Read Only

[trim matrix]

wait how do i set a folder for my saves anyway?

[versed sun]

default should be ProjectName\Saved\SaveGames

not sure how to change it

but if it saves , it should generate a file there

[trim matrix]

ok

[odd veldt]

Is there a way to connect this? (Actor is not choose able in Blackboard but I used Object -> Actor)

[ruby flare]

Heya, has anyone here tried using DataAssets as a place to write data to at runtime as well as read from? Good idea / bad idea? I want to have a sort of globally accessible, static place to store things that are currently all kept in a subclass of the GameInstance and have getters for various values which will do a quick lookup in a cache, then potentially do a slower calculation if the value's not found etc.

[ruby flare]

Cast to Actor?

Tbh, what I'm trying to achieve would probably be done better by writing a subsystem in C++ but the project is currently BP-only and I'm not ready quite yet to fight the battle persuading everyone to change that...

[gentle urchin]

Nobody has to know that you converted!

join the dark side

[ruby flare]

Hahaha

[gentle urchin]

Jokes aside, havnt played around with data assets yet

I went way above and beyond to get shared attributes among my ai

Only to realize a single data asset would solve it

Atleast to my understanding

[ruby flare]

🙂

[twin pine]

@gentle urchin Figured out what I wanted. I needed a class reference instead of object reference

[gentle urchin]

I was gonna suggest it but felt it was to obvious 😅

[twin pine]

Yeah I'm new to unreal, used to working in frameworks and some unity

[gentle urchin]

No worries, you'll get around, im sure

[short reef]

I'm currently pondering how best to handle hitboxes. I'm making a game with both melee and ranged attacks, with characters who use both body-based melee attacks as well as attacking with weapons, so I can't just stick some hitboxes on a sword actor or something, activate them during an attack and call it a day.

Ideally I'd like to do per-frame melee hitboxes ala traditional fighting games but it doesn't seem like there's a straightforward way to do that in UE.

[ruby flare]

Could you have a few hitboxes that get turned on/off at various points during the animation? Like on the fists/knees/sword etc?

[short reef]

And probably not the most efficient method outside of 1v1 fights.

Maybe.

I might have to give that a shot.

[gentle urchin]

Did i miss the section where you explain how slapping a few hitboxes on them doesnt work?

It sounds like what id do,

Using notifystates to toggle them on and off

[short reef]

Well I mean I can't just create a seperate object that handles everything

[gentle urchin]

The weapon would hold its own collision, fist fighting is also a 'weapon' just without a mesh

Ranged would be faked in whatever manner you feel fit

Anywhere from just linetrace to sweeping

[short reef]

Or just projectiles, which fortunately actually have a standard component

[gentle urchin]

Yepp

They'd be unrelated to per frame hitbox control anyways

[trim matrix]

ill check

[wheat niche]

Hi guys. can somebody explain my such a thing. A make a bool var. expose it to cinematics. animate it from sequencer. Make a brunch with a bool condition. And brunch always skip condition on 1 tick ....... why does it happen?

[cyan bone]

This node gets the closest distance between a point and a line. Is it possible somehow to get the point in my line where this distance is being calculated from? Maybe there's another node that i dont know of?

[earnest tangle]

You could calculate it with some trigonometry at least, maybe some other ways too

you basically have a triangle forming from your points

[short reef]

Though now I'm wondering how a notify state can tell an actor to active/deactivate a collision volume unless it's a very specific actor with a function for that purpose

[earnest tangle]

Or that lol

[cyan bone]

awesome. thank you. thank you too zomg i think i will go ryck0shae way, than going full math lady 🙂

[serene bramble]

Anybody able to suggest places where I can find reasonably good textures/materials for my game? After a couple wood and stone ones. Nothing 4K or stuff as it's too big for my project

[earnest tangle]

I'd just look on Megascans, you can always scale them down if they are too high res for you :)

[gentle urchin]

Well there are many ways really. Interfaces is an option

Depends on your setup really

Id just cast to my master pawnclass and call the activate/deactivate functions

Which would handle it accordingly, depending on whats equipped

[north ore]

Hi, I was wondering if I may have some help? I don't mean to interrupt, I apologise. I'm a beginner to unreal engine and I've been following various tutorials to create a first person melee combat system. I've got all the animations setup and working, I'm just currently struggling with line traces and actually getting the animation to apply damage. Each tutorial I've looked at seems like it does it a different way. Currently I've got a damage anim notify state blueprint setup, where I have the top and bottom sockets of my weapon skeletal mesh in the socket location, which is then connected to a sphere trace. However, I can't figure out how to get it working, when in play mode the sphere trace appears when swinging my melee weapon like it should, but is coming out of the bottom of my character rather than the top and bottom sockets of the weapon skeletal mesh which I want it to. I'm not sure how to fix this or if there is a better way entirely, I'm not sure what the best way to get line traces setup is.

[tawdry surge]

I usually just make a collision for the weapon and allow hit events only during the swing with a bool.
For your method it sounds like the values for the start and end of the trace are offset for some reason. Do you have a screen shot of how are you getting the positions

[sharp fox]

how i can detect "on exit event"

[short pawn]

@sharp fox you can set a boolean variable as true when you exit and check it with a branch

[sharp fox]

but what if user exit with alt + f4

[gentle urchin]

Then they quit

[sharp fox]

but i want to save the game before quit

One of the major problems with this is that there is no context for type of gameplay.

There is a large design implementation difference between a hack and slash fast paced game and a slow paced fighting game like say Kingdom Come.

Fast paced requires less precision and simply hides this with flashy animations and visuals. Spawn/use a large collider, test hits, apply damage, play FX, done.

Slower paced games require much more implemented designs. You need to know if a weapon is hitting something visually or it looks bad, most times traces can handle this on tick if you manage a decent fps target. More importantly, they require a heavier fighting system setup because of usual stuff like blocks or parries, and required animation state changes, etc.

colliders also work fine. But you really need to know what the enemies in front of you are doing to. If you're mid swing, you need to know what you might hit, if they're parrying, etc. It helps you manage animation state changes more smoothly. Looks a little less jarring.

[gentle urchin]

Isnt mesh component the skeletal mesh of the character and not the weapon?

[north ore]

Yeah that's what I was thinking, I think the mesh component is referring to the anim montage, which contains the animation of the character mesh swinging the weapon, skeletal mesh. Idk how or if I'm able to specify that the location of the socket is in the skeletal mesh of the weapon.

[gentle urchin]

Dont think you can, directly

Prob easiest going via the char bp

Or exposing the weapon ref somehow

[north ore]

Yeah I've followed many tutorials and tried that. I've got a weapon pickup system and I haven't been able to figure out how to get it working in the char bp alongside it. My issue is that when adding the skeletal mesh to char bp it adds it to the viewport, which I don't want, and adds the line trace only to that mesh. When I go into play mode the trace works but the weapon is attached to the viewport. I don't want the character to have a weapon by default, but be empty handed and so when picking up the weapon and swinging line trace works, the line trace also doesn't appear on the weapon mesh. I think it's because the weapon is a bp containing the skeletal mesh and collision which I'm using to for the pickup system.

[gentle urchin]

Single player?

[north ore]

currently yes, but I might test out with multiplayer in the future possibly if I get some of combat and that working

[gentle urchin]

The weapon should probably be a mesh/skel mesh attatched to the appropriate bone in the char when equipped

Char having a ref to the weapon actor

And being able to toggle its collision/damage state

[north ore]

How would I go about doing that? Apologies, I'm very new to this lol

[gentle urchin]

Id let the weapon handle the damage

So a master weapon class with some basic definitions and functionality

Which you then reference from the char (with a variable) ,

So that in the notify state you can do GetCharacter -> Cast to myChar -> GetEquippedWeapon -> Enable collision

Notify state begin would start it, and notify end would stop it

Thats atleast how id do it from the top of my head

[north ore]

I think I understand, I'm gonna try see what I can do, thank you!

[north ore]

What would the master weapon class include?

The pickup & melee attack system/ nodes

[gentle urchin]

It would include all definitions, variables and whatnot that you'd need in every weapon

It doesnt need the implementations, but it makes sense to at the very least toss you a bone with print strings if its something that must be overriden in a child class

And add any common implementation that you want every weapon to have

By definition i mean the decleration of functions really. So they can be called via the masterclass

[fervent kelp]

hi guys i'm using "material parameter collection" with "vector" value for storing level actor's world position. my problem is when i duplicate that actor on level, duplicated actor's vector position gone and stored new duplicated actor(it's working normal). how can i handle multiple actor's positions in parameter collection dynamically? afaik there are no arrays values type in parameter collection?

and afaik we can't add or delete values at runtime on parameter collection..how can i handle this?

[tame kite]

Hey, i was working on something and ended up running into some slight issues (i do have some ideas on how to move forward but that involves using a savegame so basically i was wondering if there is a better method around this).
So my issue is that i'm working on moving AI characters from a Lobby to In-Game. These AI characters will have data set on them when spawning into the lobby (Names, Stats, etc) but i noticed when i move between levels it does leave references within the array I tried storing Lobby players in but after moving maps it would destroy the map, the AI in the map and all the data connected to the references (i can check the array and see the index's are still there, but i can no longer get data from the destroyed AI from the previous map).

[finite flax]

Can someone please help a noob question here: like in this video, after I insert the tube within the socket, I want the "Damaged Optical Fiber Cable" widget to change to widget that shows normal cable (indicating it has been fixed)
What should I add in the blueprint?

I know how to do it if it was a material and I wanted to change the material I would simply add "Set Material" and do it easily, but with widgets I'm not sure what to do.

[north ore]

I'm quite confused, do you know of any tutorials that might show the process?

[gentle urchin]

Just start out by making the big broad strokes and functions in the masterclass

StartDamage, EndDamage, GetDamage,

Keep variables private, functions public

I can smack something together in an hour or two (or three)

Stuck babysitting now :p

[sharp fox]

How it is failing https://blueprintue.com/blueprint/sh499jxq/

[gentle urchin]

Wrong savegame object type

Print its displayname

[sharp fox]

not printing

it just print "it failed"

and on object name it just prints "none"

[gentle urchin]

Soo

What type of savegame object do you have in your settings?

None?

[sharp fox]

wait.. settings?

[gentle urchin]

Is it even valid ?

[gentle urchin]

The savegame object

[sharp fox]

in content browser?

[gentle urchin]

No, when you cast

Is the incoming object even valid?

[sharp fox]

i think so

its load game

[gentle urchin]

Check it.

[dusty sky]

have you used an is valid node?

[sharp fox]

in my life: yes
in this blueprint: no

[opaque acorn]

Guys im facing a problem , i just forgetting which set function to use to give another blueprint access to player controller.
I sae a video few weeks ago to use. Get player controller but I'm forgetting where to plug the return

[sharp fox]

i changed the slot name and now it works

[dusty sky]

W

[gentle urchin]

So the slot exists

But is not the type you think

Or is just broken

[dusty sky]

Life is easy. GameDev is hard

[sharp fox]

theory: easy
practice: hard

[gentle urchin]

You can check the folder for the file

And prob just delete it

If you struggle with corruption it might be worth adding some functionality to fix it aswell

If cast failes but slot exist, try to delete the slot, before making a new one etc

[last walrus]

hello everyone
I havent opened UE for like half a year and forgot almost everything...
I have a widget class "ArrayCounter", it has text block named "Counter". how do I access this text block? I'm trying to cast but looks like it wont work

[gentle urchin]

Ugh

CounterOnCube, is that a widget component or what

[last walrus]

yes

[gentle urchin]

So you need to get the widget inside the component

[last walrus]

I guess yes

[gentle urchin]

So...

GetWidget

Cast to ArrayCounter

[gentle socket]

is there a way to save data similar to how a data table is filled?

Or would I have to create my own storage class

[gentle urchin]

The last one, yes

[gentle socket]

Not sure how convenient it would be to edit and save instances for that

Is it possible to give a BP an array of "wildcard" structs?

might be possible to load in data tables then

[gentle urchin]

No

Not easily done in c++ either

Wildcards, that is

[gentle socket]

hmm

For context, I have been writing a bunch of blueprints that are set up from the data from data tables

with different structs

I thought it would be nice to have an editable alternative so that users can change them like settings

[last walrus]

uh... can you explain what's wrong on my screenshot? I dont understand what you meant

[gentle urchin]

Ur getting the widget component. You need the widget inside the component

[last walrus]

I cant see it in the context meny...

[gentle urchin]

Get widget?

[icy dragon]

auto

[last walrus]

oh, yeah
finally
thanks

[lime yoke]

Hey guys, got a question. Not sure if this is possible (if not, it's not a big problem).
I'd like to know if it's possible to paint in gray Enemy Name (block user to open dropdown menu) if Random Enemy is true.

In this particular situation it won't be a problem, but I think it should help in future situations.

[maiden wadi]

It is. But not in blueprint I don't believe. At least I do this in some UWidgets in a plugin I have. You have to override the virtual CanEditChange from UObject. This lets you return whether this property can be edited.

[lime yoke]

Thank you! I'll take a look at that.

[maiden wadi]

A basic example might be this to give you a head start. I have widgets with a bool property named bIgnoreStyleData. When this is true, it disables BlurStyleData and enables BorderBrush and BlurStrength. When it's false, it does the opposite.

.h

#if WITH_EDITOR
    virtual const FText GetPaletteCategory() override;
    virtual bool CanEditChange(const FProperty* InProperty) const override;
#endif // WITH_EDITOR

cpp

#if WITH_EDITOR
bool UAuthaerColoredBlur::CanEditChange(const FProperty* InProperty) const
{
    if (Super::CanEditChange(InProperty))
    {
        static TArray<FName> InvalidPropertiesWithStyling =
        {
            GET_MEMBER_NAME_CHECKED(UAuthaerColoredBlur, BorderBrush),
            GET_MEMBER_NAME_CHECKED(UAuthaerColoredBlur, BlurStrength)
        };
        
        static FName ValidPropertyWithStyling = GET_MEMBER_NAME_CHECKED(UAuthaerColoredBlur, BlurStyleData);
        if (InProperty->GetFName() == ValidPropertyWithStyling)
        {
            return !bIgnoreStyleData;
        }

        if (InvalidPropertiesWithStyling.Contains(InProperty->GetFName()))
        {
            return bIgnoreStyleData;
        }
        
        return true;
    }

    return false;
}
#endif // WITH_EDITOR

[gentle urchin]

Meta specifier for this

To grey out /make them un-editable

[maiden wadi]

Is there one to do that?

[gentle urchin]

Ye

[maiden wadi]

Can you set that in BP through the categories or whatever it is?

[gentle urchin]

It even takes statements 😄

No, must be done from cpp afaik

[maiden wadi]

I might stick with the CanEditChange. Too used to it. 😄

[gentle urchin]

https://forums.unrealengine.com/t/usage-editcondition-in-uproperty/307893

EditCondition

[maiden wadi]

Huh. Will have to keep that one in mind. Certainly faster than a function override.

[gentle urchin]

I used it to interlock land/water buildings

So it couldnt be none, but either, or both

[candid geyser]

I tried getting this to work earlier, but I still havent succeeded. Im trying to make the stamina bar on my widget flash when the bar is under 25%, any suggestions?

For getting the actual animation to play of course

[gentle urchin]

During stamina use, check for the condition

Launch an event dispatcher when stamina goes below your treshold

On stamina regen

Do the opposit

A single delegate with a bool should be enough

Below treshold, true or false :)

[faint pasture]

I'd do it in the material myself

[candid geyser]

how would I do that?

[candid geyser]

I'll try this first!

[faint pasture]

Make a material that can flash and has FlashAlpha and maybe FlashSpeed parameters.

[gentle urchin]

Personally id find that way more troublesome 😅

Need to make dynamic material instance aswell then

[candid geyser]

Yeahhhh I tried the material method and got nowhere

[candid geyser]

Hmm, could you elaborate a little on checking for condition?

Also, do you think I should make it a function?

[gentle urchin]

Which part

Id do that yes

[candid geyser]

All of what you told me to do

[gentle urchin]

The widget would have a function

For playing the anim, and for stopping it, based on an input parameter

This function shall be bound to the pawns stamina delegate, which also has a bool 😄

[candid geyser]

Here, ill show you exactly what im working with

[icy dragon]

Well, I already linked you the snippet of the material, meticulously commented and all

[candid geyser]

Oh I forgot im sorry :')
I took a brain break shortly after I asked originally

Here lemme check my mentions so I can find that again

[icy dragon]

Though I should clarify, I prefer materials because it'll save some load on Game thread's part

[candid geyser]

As in performance?

[gentle urchin]

This very time limited operation shouldnt cause much of a dent tho

But many rivers small.. i guess

Extremely many micro rivers.. etc

😄

[candid geyser]

Ah! Found it! So, theoretically all I should have to do is substitute for the values I want to use?

[candid geyser]

I mean hey, and performance saved is good, right? :D

[icy dragon]

Yes.
The check is done in shader level, saving performance on the game thread, and all you have to do in game thread is just setting the percentage value.

[candid geyser]

Oh wow this looks

Overwhelming :')

[gentle urchin]

😂

[candid geyser]

So many actions im not familiar with

Such is the process of learning I guess

[gentle urchin]

Indeed

5 years, still learning

Trying to improve :)

[candid geyser]

A h a h

Im a little over a week in :')

But im intentionally taking on an ambitious project first, because, well, im very ambitious, and im also a perfectionist so, I know my brain wont let me stop until this stuff looks really good

The project is ambitious so im forced to work with more, and learn more haha

[gentle urchin]

Best of luck !

[icy dragon]

For context, the snippet in question
https://dev.epicgames.com/community/snippets/QkV/progress-bar-material-with-danger-pulsing

[gentle urchin]

Next zelda incoming

[candid geyser]

Ahah! You already know by my pfp it's gotten some inspiration :')

[candid geyser]

And yup! I have it pulled up, im just trying to mentally go over it all because it's turning my brain a little

Okay I THINK im kind of getting and idea

[gentle urchin]

I gotta check this out! Seem like a good snippet hub

[candid geyser]

Should I remove the flash animation from the widget itself as well or is this going to utilize it?

[icy dragon]

The material is all in one, really. You just have to apply the material into an Image widget

[candid geyser]

Ohhh okay nice!!

I see now!

Will update if it works!

[candid geyser]

Woah this is 874 lines of code long

[gentle urchin]

Yepp😅

[candid geyser]

Im so happy we have blueprints :')

It makes the process so much easier and faster

Hope you guys enjoy my company by the way, because im probably gonna have to come back here a lot :')

[icy dragon]

I'm sure manually typed HLSL code of the same thing could be way shorter
I just comment things a lot just to give clearer idea on what's going on

[candid geyser]

Oh you made all of this?

Well, there's definitely things in here that I have no understanding of :')

[gentle urchin]

Pro contributor

[candid geyser]

Are things like PulseSpeed custom params?

[icy dragon]

Well, I mean, who else in the site used Makoto Kikuchi profile picture? :P

[candid geyser]

I didn't pay attention to that- :')

[icy dragon]

Yes, just scalar parameters

[candid geyser]

I really wish all action blocks had some kind of brief description

I wonder if Blueprints or C++ are harder

my third eye has opened

now that

is quite ugly

no dont take notes

dont listen to a woman who owes me $5,000

[late gorge]

so a level that i loaded after 2 weeks is now suddenly failing to load with the error:

Error: Couldn't find Shader (TMaterialCHSFPrecomputedVolumetricLightmapLightingPolicyFAnyHitShader, 0) for Material Resource DefaultDeferredDecalMaterial!

i havent used the material

[candid geyser]

You spent two weeks loading it?

[late gorge]

i havent changed the levels

[late gorge]

-.-

[candid geyser]

you said after two weeks

[late gorge]

i haven't loaded it in 2 weeks

[candid geyser]

OHHH

i knew that

[late gorge]

no

[candid geyser]

Could I also apply this to my players health when it gets too low?

[icy dragon]

Yes

[candid geyser]

you are my hero

well you will be once i have it functioning

[gentle urchin]

Damn. Was hoping it was my turn

[candid geyser]

you are not yet
