blueprint

[turbid pecan]

I kind of want no deviation if possible. Like.. I need to figure out the spacing eventually via blockout and stuff. But the primary goal is:

Each "square" on the "grid" is equal. Therefore if I go forward and it's a wall, itll let me come up to it, but go no further. Kind of like...

So pretend those are even squares and that I can draw

So you start at 0 - inert. You click W to go forward once, you're in sq 1, then W again to get to sq2 and then youre facing a wall. Pressing W again will not let you move forward

[neon lion]

is it possible to make my weapon type var into an enum that will still function like an integer for this purpose?

[turbid pecan]

@remote meteor i guess the other q would be - is it a sane option to set my collision to be as wide on x/y as a potential grid square. Like would this help ensure I always move and collide accurately relative to the size of the grid?

[remote meteor]

not exactly a good compromise, you want to trace with a square to know whether there is a full square available or not

or also to trace with your character collision capsule

so maybe square trace or capsule trace, instead of just a line trace

[neon lion]

i would say that you want to be colliding with the edges of tiles, rather than objects
your walls are essentially 2D in function, appearing along the boundary
this sounds like an application where you dont want to do collisions or tracing at all, just check variables in tiles to see if it should be enterable

[remote meteor]

you might want to create a enum, with how the weapon is "held", place it in the weapon class

from the class, get defaults, get which enum it is

[turbid pecan]

Well I intend to design the levels so that they are never mismatched in terms of size (IE no half squares or anything like that), I kinda just want to stop when theres no free square in front

[remote meteor]

and with this, you can use blend pose by <yourenum> instead

[turbid pecan]

or not go back if theres a wall behind me.

[remote meteor]

trace before move, if its empty, move.

Hi, I'm having some trouble with my approach to spawning actors. I have a bunch of Actor blueprints for cards. I want to spawn all the cards in the deck at the beginning of play. The spawn actor node works if I manually specify which actor to spawn. What I want to do though is build the deck from all actor blueprints with a certain tag. The only node I can find for get actor with tag though looks for actors in the world - how can I find all actor blueprints with tag that aren't yet in the world?

[turbid pecan]

So like I am doing here?

[remote meteor]

yes, maybe could be alittle more organized, and use a box/capsule trace instead, but yeah, essentially correct

[turbid pecan]

maybe could be alittle more organized
100%, I tend not to org until I know I got something correct, cause itll just get undermined by me fiddling with it again.

Im a messy boi

Thanks @remote meteor - I will try to fiddle with this and see what I come up with.

I might pester you later if I get stuck, if you don't mind

[pulsar vigil]

Hey , im buggued on something : i Have a BP_Area with a Box Collision and a BP_NPC i want to when the NPC overlap it, this specific npc fire an event, on his graph or wherever it need to be, and i was thinking about event dispatcher but the problem is that i need to target the only npc that overlap it, what would u do in that situation where *my event fired should be ?

[polar sphinx]

OnComponentBeginOverlap implemented on the BP_Area, and using Get Overlapping Actors to get the NPC object reference to then do something with it?

[pulsar vigil]

u mean make it a variable to use it anywhere i'd like ?

[remote meteor]

it depends whether you need any information from the Area or not
if there are more than just npc that the Area should react to, Area should be the instigator of the event

[pulsar vigil]

Just the npc for now but more later

[remote meteor]

then BP_Area should be the event instigator

[pulsar vigil]

i didnt thinked about promoting "other actor" from the oncomponentbeginoverlap

so i can reuse that variable is that not a bad idea ?

[pulsar vigil]

so yeah it need to be in the bp_area if its driven by the event begin overlap ?

[neon lion]

why cant i find my custom enum type, EWeaponAnimationType

[ocean crow]

Hey everyone, I'm new here so I'm not sure if this is the correct channel to be asking questions about replication, please let me know if I should go somewhere else.

I have a question regarding inventory replication, I'm making a spatial inventory system based of off Reid's 4 part series, but I need it to replicate and work in multiplayer. I have an issue currently where the server is correctly aware of the client's inventory, but the client constantly thinks it is empty. Is there something obvious I'm missing about replication here or is this not a replication issue? Let me know if you need more info.

[neon lion]

bleh i converted it to int and that worked

[remote meteor]

needs to be BlueprintType

wait

does it

🤔

yeah it does needs it

[lusty shard]

is it required still to "Add Mapping Context" nodes for enhanced input to work?

is there a built in way to use it by default?

considering old input system is being deprecated, this is kinda awkward

[neon lion]

that has worked!

[steady night]

refresh my memory im after "if either is false then do false

or rather if either is true then do true

should it be nor ?

[lusty shard]

you have "if either is true then do true"

[steady night]

erhm

oh right

my misstake >.<

[polar sphinx]

I have 5 cards that are child classes of 000_Card_Base. How can I spawn all 5 cards via blueprints without having to manually place them in the world?
I've looked at spawn actor node, but it requires I specify the class to spawn so I'd have to have 5 spawn nodes. Doable for now, but not when I have hundreds of cards defined. Any suggestions?

[versed sun]

I think this gives you "If either is False, then False"

[dark drum]

Create an array variable that is the class type of your base card. You can then add the types of cards you want to spawn. It would just be a case of looping through them and using the class as the type for the spawn actor.

[steady night]

@versed sun yeah ty

[polar sphinx]

Ok, how would I add the cards to the array?

[remote meteor]

isnt that just AND gate 🤔

[dark drum]

That would depend. You can dyanamically add them at runtime as needed or specify them in the var defaults.

[polar sphinx]

that's the problem I'm having though. I can't find a way to get a reference to them unless they are placed in the world. Get All Actors Of Class only looks at actors in world

[dark drum]

You would be specifying the class type (purple) not a spawned object. (Blue)

[polar sphinx]

Sorry, I'm not understanding. I've created an array variable of type class reference to 000_Card_Base. I'm still at a loss though of how to add the cards to the array.
I suppose I could use the event BeginPlay in the 000_Card_Base, cast to player, update player deck array variable with self.

Hmm, nope. That only runs for each card actor I've manually placed in the world

[dark drum]

Show what you've done.

[harsh wasp]

Hii,
I need some help with integrating a plugin into another one, if someone can help me, I would really appreciate it.
https://www.unrealengine.com/marketplace/en-US/product/character-interaction
https://www.unrealengine.com/marketplace/en-US/product/inventory-system-blueprint

[polar sphinx]

So I've got the cards, and each of these cards has a tag Card.Level1 which identifies them as cards needed for Level1.

An array variable in the player pawn which I want to act as the players deck. No default entries.

In GameState, off of Event BeginPlay I want to find all cards tagged Card.Level1, spawn them into the world and update the player deck array so I can keep track of them.

[dark drum]

You need to specify the cards using the class to know which ones to spawn. You then use the array of classes to spawn them in the world.

[edgy ingot]

That requires someone to dive deep into the plugin and then implementing the integration. We are talking about loads of hours here just so you are aware.

[thin panther]

It also depends a lot on the plugin and what you want

It's not something we can really help with

[polar sphinx]

Like this?

[main lake]

Is there a premade method for the nameplate on top of players to always face the camera of the local player ?

[lusty shard]

We (showing off lol) making an rts style building system

[dark drum]

Pull from the purple pin, promote to variable and then change to an array. Then add the card types you want to spawn. Loop through the array and use the class to spawn the cards.

[edgy ingot]

What name plate? You mean widget? Use screen space instead of world space

[main lake]

you're the best

[edgy ingot]

You will need to change the size tho based on distance

Well depend on your game but thats what i did with my player name

[polar sphinx]

Pulled from purple pin, promoted to variable, changed type to array. Unsure on how to do the next bit, add card types I want to spawn

[delicate anchor]

hey this os my first message here if i asked in anything in blueprints would you guys help me out and when do you be available

[dark drum]

Unhook the var from the spawn actor node. Pull from the class var and add a for each loop.

[main lake]

how ?

[polar sphinx]

Ok, done

[steady night]

hey im using this to rotate actor towards another actor it works fine

[thin panther]

Out of curiosity what was your scaling algorithm for it? I've been playing with a bunch and none of them feel juicy to me

[steady night]

however i would like it to move the shortest path sometimes it dose a full spin tips ?

[edgy ingot]

I just set a ranged map value based on the distance between the player camera and the widget in world space.

It does require some tuning but i find a sweet spot for my purpose.
Can show you in 10 mins, trying to rejoin the server on my pc atm

[steady night]

anyone got some tips for me +

[spark steppe]

% 180 (on the rotation delta)

[frosty heron]

@thin panther @main lake
Might not be the result that you want but I don't know a better algorithm. Would be nice to see how other people actually do it

[thin panther]

Yeah that's pretty much the same thing I did.

[frosty heron]

would be nice if World space just solve this scaling issue but problem is I can't get the same quality on the text and it's flickering non stop 😦

[thin panther]

I was trying to find the way billboards do it, but it's all hidden in the view matrix calculations, which makes sense but is annoying

[honest turtle]

Hello everyone! I'm struggling with a localization problem ...
I can't localize assets, I have 8 languages and I have compiled them like 10 times, but when I right click on assets, only the native language appears.
Can anyone give me a hand? I would be very grateful...

[main lake]

I think I just realised that it will create an issue when the player is behind another player or behind obstacles, so I guess I have to make it "World" instead of "Screen" ? 🤔

[frosty heron]

pros and cons

[frosty heron]

I can't get a nice render for world space

[main lake]

Like I'm trying to do the same way minecraft does it

[frosty heron]

Yea, for that. I kinda shoot a trace every frame and see if there's anything blocking the widget and the camera

[thin panther]

Couldn't you just rotate the widget component to face the player.

[frosty heron]

if there is something that block it, I will set the widget to be invisible

[thin panther]

Or coldsummers version for screen space :P

[frosty heron]

You can rotate the widget to face the player like Cupa said

[main lake]

That was my first question, if there's an already made to rotate the widget to the player like "LookAt" or something like that

[frosty heron]

but I kind of give up on doing world space widget atm 😢 . The widget keep flickering constantly. Skill issue I guess

[frosty heron]

There isn't but that's like a few nodes

on tick just set rotation

[dim agate]

https://www.reddit.com/r/unrealengine/comments/alzsqi/weird_lerp_behavior/ This might be relevant to your problem.

[thin panther]

Just set the component rotation with a find look at rotation

[sand spoke]

Is there a way to accurately set pivot offset?

[thin panther]

Yeah I've heard plenty of issues with them 😔

[remote meteor]

i rather make them screen space and check whether they should be visible or not

biggest issue is with clipping

[sand spoke]

Can I set pivot offset here?

[honest turtle]

Hello! Does someone know how to fix this?

[remote meteor]

have you tried, gather text, and compile text, and see if it shows up in asset localization menu?

[tough igloo]

I have a static mesh I want to move on an axis, my understanding is I can use "Set relative location" as seen in this tutorial: https://www.youtube.com/watch?v=exs1uMuqQSE

Attached is a picture of the blueprint that i set up.

However, when I tried this in my project, the static mesh is moving directly to world position 0,0,0 and then lerping to 0,0,-100. Its parent is located at 290,2050,60, so shouldn't it lerp from there to 290,2050,-40?

I tried using a print string, it shows its world position and relative position to be the same. Shouldn't they be different? I'm missing something here.

[fluid lagoon]

Was wondering if someone could point me in the right direction. Trying to get a camera to move when the button is pressed however it doesn't work, the button detects using the print that it's being pressed but then proceeds not to play the timeline. First image is the Widget button event and the second is the custom event I'm trying to run, if anyone could help I'd be very thankful!

[frosty heron]

perhaps your actor is sitting on 0,0,0?

Relative location is relative to the parent, so if your parent is on 2000,2000,2000 and your relative location is 0,100,0 . The world location for that component is 2000,2100,2000

[steady night]

How do i remove so using the Tab key dosent Cycle thru UI ?

[tough igloo]

Hmm... As far as I can tell, the actor is at 290,2050,60 - but when I fire this event it moves to 0,0,0 then lerps.

[frosty heron]

don't know what goes on your end but you can always print string to check.

there might be some code that you did to move it to the world origin too.

I suggest to add a break point at the time you are moving the box and see where that takes you

[opal pasture]

Im getting mad more - my montage does not play and blueprint execute is fine. Its equipping sword and hiding it on notify but montage does not play. I've tried vaulting over objects too but even that doesnt work.

[frosty heron]

check the montage slot and debug the anim bp. Also make sure the skeleton are compatible

[tough igloo]

Ah yeah, print string shows the world position and relative position of the static mesh to be the same, even before I move it. That's what I'm having trouble understanding. It seems the mesh should be at position 0,0,0 relative to its actor

[frosty heron]

the mesh can be in any position

Show your blueprint and print screen the components

[remote meteor]

you will have to disable it through c++, creating and overriding the UNavigationConfig by using FSlateApplication::SetNavigationConfig

[tough igloo]

I can add a "get world position" node and it works as intended, but I just am trying to understand why mine doesn't work like it did in that video.

In my map view, the instance of the box shows a position of 290,2050,60 and the child mesh shows a position of 0,0,0

[fluid lagoon]

Fixed it

[frosty heron]

@tough igloo Don't know what the video do or what you do on your end, but this is a simple way of moving the box relative to it's location

make sure the Alpha in your timeline start with 0 and ends with 1

[opal pasture]

skeleton shall be, cuz its same mesh and skeleton with bones. But this is weird. Cuz Everyting is executing but not animation. I've followed whole tutorial before with vaulting and my vaulting "worked" but without the animation montage too, checked code several times and matched 1:1 like in tutorial. I'm passing this slowly

[frosty heron]

Pretty sure Triggered run every frame btw

try to use Started pin instead

[opal pasture]

nah, does not work. Tried on every execute in IA

and tried to change on TAP in IMC

[frosty heron]

Forget your logic for one sec and play the montage using a key

see if that work

if a simple play montage don't work, I can only suggest to look at your anim bp

see where the montage slot is called and if it's playing at all

[opal pasture]

nope woknot - ill check that

[boreal wing]

hey, so i combined two BPs to get their features in one BP, they both generate spline meshes, but in one of them when i use the repeating spline mesh i get this result, i thought it doesnt work together but if not then how is the periodic is working fine? is it something simple i have to fix or do i have to search in the BP?

[steady night]

@remote meteor oh okey, in what class ?

[remote meteor]

i did it early in UGameInstance:Init

[steady night]

hm i dont have that one

is that your custom one ?

i have a custom game instance but its BP,

[remote meteor]

only in c++ since setting the navigation config is in FSlateApplication, which is a c++ only thing

[steady night]

yeah but my project is converted to c++ so i can acess that

u jsut need some default class that i can use it it i suppose ?

cant i put it in player controller ?

[remote meteor]

it makes sense to set in game instance since its something that you only need to set once per launch of the game

wherever its fine, just make sure its called before the first navigation is possible

[steady night]

i just put it like this or ?

[frosty heron]

🥹 you remind me the days I don't have Rider

[steady night]

he since i dont use c++ "yet" vs surfice work fine enough with c#

[remote meteor]

why is it vanilla like that though

you have to create your own CustomNavigationConfig first or maybe you dont, you just need to
FSlateAppliction::Get().GetNavigationConfig().bTabNavigation = false; and see if it works

[honest turtle]

Yeah I tried but it doesn't work 😦

[steady night]

hm ok so sounds like alot of work for a rookie :/ il just use nanother button i suppose

[frosty heron]

Try his suggestion?

[strong dome]

Hello .
I have a question about ice.
Well i want to make it that when i run up from 0° to 30°angle what do i need to do for my character to have -run speed slower and once i stop or i em not fast inaf ( with deley) the character starts falling back where i started. The base friction and deceleration is done of sliping ice. But the rest i have no clue. Tryed to find but nothing of that info.if you can help or some hints it would be nice. So it could be like one BP where i can place it down and boom the effect is there or it needs to be between the character and the bp interaction.

[vestal sapphire]

What do "Activate" and "Deactivate" nodes actually do?
I tried using them to temporarily disable the collision sphere component I have around objects, but it didn't work. Is there a function to turn components on/off?

[spark steppe]

they turn of tick afaik (which won't help you for collision i guess)

or hmm, maybe your issue is something else

is it possible that auto weld is enabled in the component?

then it get's kind of merged with your actor

[opal pasture]

Is that possible if i have a state machine, should i put montage there? Cuz i've put everything into character bp

[frosty heron]

wdym by if you should put the montage there

you should have a montage slot somewhere in the anim bp

normally right after the cached pose

[opal pasture]

i mean i was making every montage in character bp instead anim bp, maybe this faults?

[vestal sapphire]

Yeah, then they won't do me any good here. I'll use Set Collision instead. But weird that there isn't a "on/off" function for components.

[polar sphinx]

@dark drum thanks for your help. I eventually realised there was a drop down in the array default values to specify the classes. Now with those entries added I was able to loop through it and spawn them 🙂

[remote meteor]

those active and deactivate are the on/off, problem is epic did not make the Activate and Deactivate function to adjust anything in a UPrimitiveComponent

[opal pasture]

I am really dumb. I've delete "default slot" from abp and now it works

sorry for bother

[sacred canyon]

something that Ive been wondering, how do you even create like universal events? so for example Ive not been able to use the default Damage nodes since they dont have enough information on them, such as attacker, attack direction, push force etc so I end up having to individually cast anyway. but how could I make one node to use across any actor somehow?

and Ive also been needing some kinda generic "start" node, so I could call start on any actor then they would have their own scripts that get activated after that. not begin play, a start node that can be activated when needed, for like a trigger system or something

[frosty heron]

wdym by individually cast. What are you casting?
For damage, you probably want a struct that contains all the info that damage in your game need

@remote meteor Thanks for sharing, this work but maybe I can reduce it to one line? 😛 Gonna try to set the boolean without calling SetNavigationConfig see if that work

[vestal sapphire]

Blueprint Interfaces is what's you're probably looking for.

[sacred canyon]

ah, so that would be a custom function usable in other actors?

[frosty heron]

@steady night did u get it working?

[steady night]

nah

[frosty heron]

Asaka one line code work for me

@steady night FSlateApplication::Get().GetNavigationConfig()->bTabNavigation = false;

[steady night]

it worked for you ?

[frosty heron]

yes

show me your code

[steady night]

where did u put it ?

[frosty heron]

where you put it don't matter, but like he said, when you want to do something once then On Game Instance init is a good place

[vestal sapphire]

It's basically an event that can be triggered from another blueprint. You can add whatever values you wish to pass through.

[frosty heron]

for my case I also did it in game instance init

[steady night]

yeah well since my game instance is BP i cannot put it there

or i could use the parent game instance .O ?

ofc

[frosty heron]

Ofc

you can do it anywhere as long u call it before u are inside your widget

[steady night]

yy

so where would i put it inside the class

[frosty heron]

I would say just make a cpp game instance class and reparent your BP game instance to the game instance class you created

Have u make the game instance?

[steady night]

my custom game instance bp class is a child of the c++ Gameinstance i can just use that one ?

[frosty heron]

Nah don't touch engine stuff

make a child of GameInstance

[steady night]

oh ok

ok

did that

[frosty heron]

Show code

[sacred canyon]

I can call the function within another blueprint, but how would I make a blueprint receive that function?

[frosty heron]

For something like damage, you can use interface

because you probably want to hurt something other than enemy

A barrel for instance

[sacred canyon]

yeah, I made the interface

[vestal sapphire]

You create the interface, create the function within the interface, then in Class Settings add the interface to the actor that you want to interact with. Then compile and double-click on the function and it will be add to the blueprint as an event

[frosty heron]

and you make functions in the interface? Once you done that, you just need to override the function in the class that implement the interface

[steady night]

@frosty heron cant get anything to work <:< to rookie with cpp trying to replicate your sc but no luck

[sacred canyon]

I still just get the option to call the function and nothing else

[frosty heron]

@steady night I can try to run it through with you

just show the code

[steady night]

derp

[frosty heron]

Header file

have u override the Init?

btw u just need this one line
FSlateApplication::Get().GetNavigationConfig()->bTabNavigation = false;

[steady night]

ok

have to override the init idnno i just wrote what yours said x)X

[frosty heron]

Show me your GameInstance.h file

[steady night]

oh

[frosty heron]

in your public section
You want to override init
virtual void Init() override;

[steady night]

after generate body

=?

[frosty heron]

Add this
public: virtual void Init() override;
after generated body

[frosty heron]

Now back to the .cpp file

Show me the code

[frosty heron]

Make sure to call Super

Super::Init();
above the FSlateApplication::Get()

u have capital V for the void btw

also you are using my Class name

wait let me try to write the code for you

[steady night]

yeah pls >)

[frosty heron]

void UCustomGameInstance::Init()
{
Super::Init();
FSlateApplication::Get().GetNavigationConfig()->bTabNavigation = false;
}

@steady night

[sacred canyon]

so now what, I have this in the actor but cant do anything with it

[frosty heron]

you need to feed the target, also this is not the right node

get the one with the message icon on the top right corner

[sacred canyon]

oh I had that already

[frosty heron]

you are missing include

#include "Framework/Application/NavigationConfig.h"
Add this below #include "CustomGameInstance.h"

@steady night

[sacred canyon]

is the documentation even finished it says you can use it for damage but then just doesnt show how https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Types/Interface/

[frosty heron]

you can use it for anything you desire

[steady night]

ok there we go ?

[frosty heron]

gotta make your own function

[vestal sapphire]

The interface nodes should look like this

Message you send, and the event you recieve

[frosty heron]

@steady night can you select that and screen shot

u are getting fake error messages

[sacred canyon]

yeah, thats what I need on the right, but I dont know how to make it an event

[frosty heron]

hmm never mind, I don't use visual studio for unreal. You should change it to only see the output log somehow

anyway

try to build the project see if it compile

[steady night]

did not

[vestal sapphire]

go to class settings of the actor you want to interact with (it's on the top of the bp), and add the interface you created. It will appear in your blueprint list of contents, and you just double-click it.

[sacred canyon]

double click does nothing in 4, dragging it over gives me this

oh wait

there was a right click option

ok thanks, that should be it

[steady night]

@frosty heron ideas xD ?

[frosty heron]

@steady night not compiling?

[frosty heron]

give me a sec

@steady night Show me your header file and cpp file

[cosmic kiln]

gentlemen i am here to request assistance related to camera shakes on 5.3

[frosty heron]

looks like u have linker error

[cosmic kiln]

it seems something is broken about them in 5.3, compared to 5.2

for context: i have idle and walking/sprinting camera shakes set up that work as intended in 5.2

simply switching to 5.3, ON THE SAME PROJECT with the same camera shake settings breaks them

they become very very unnoticeable

[frosty heron]

@steady night select that

[cosmic kiln]

i have no clue what's causing this

[magic crown]

@dry sleet Just thought I'd let you know an update about that Palworld question I had with Harvestable Foliage... I did some deep digging and found that they use Actor BP's for EVERY single foliage in the world.... No wonder the game runs poop. Only 30,000 actor tree BP's to load!

Definitely not taking the route they did lol

[cosmic kiln]

how does that happen?!

they didn't know that UE has dedicated stuff for foliage?!

[magic crown]

Foliage Instanced Static Mesh isn't so easy to make "interactable"..

[spark steppe]

the asset they bought didn't 😛

[magic crown]

So they resort to BP's

[spark steppe]

and foliage does support actors afaik?!

[cosmic kiln]

it does, i'm literally using them

wait no actually

i'm not lmao

i'm using static meshes

but i think it does support them

[remote meteor]

you dont have to set it again, you just need to set the public var inside from the get

since we are not overriding it completely

[cosmic kiln]

y'all know what could be happening btw?

[spark steppe]

i think palworld running like poop, is most likely due to the whole world ticking the whole time, but i could be wrong

[frosty heron]

Yup, the one line code you wrote works. Ty again 🙇‍♂️
FSlateApplication::Get().GetNavigationConfig()->bTabNavigation = false;

[cosmic kiln]

this is my code

this is run on Event Tick (YES I'M GONNA TRY TO FIND A WAY TO GET IT TO RUN ELSEWHERE)

[magic crown]

All foliage is one big instance. It gets technical with having to deal with one of the instances out of the bunch and start giving it health, items to give, etc.

That's why they're doing that stupid Actor Foliage BP garbage. It's definitely do-able through instanced static meshes. They just need to put effort into it lol

[cosmic kiln]

why's it work perfectly on 5.2 but it breaks on 5.3?

[magic crown]

And looking at the files of Palworld. Most of it is showing to be marketplace assets

[cosmic kiln]

it also just seems like a chore to place, man

[steady night]

@frosty heron send u a dm*

[cosmic kiln]

if it's manual actors, they had to have hand placed each one

[magic crown]

@cosmic kiln They're using the foliage tool to place thousands of actors down quickly.

[cosmic kiln]

i'm not sure which is worse..........

[frosty heron]

@steady night Change it to build only
then build again and see if you get any error

[cosmic kiln]

the fact they know about the tool and used it to place thousands of actors, or the fact they didn't do static meshes

[cosmic kiln]

if i can find a fix for this issue it'd be a tremendous help

[magic crown]

Now I don't know exactly how good they can make an actor perform really well in massive amounts... But they could really tone it done and basically make the Actor dormant in every way possible until players are up close. That may be their way around it

[cosmic kiln]

i intended to move to 5.3 to speed up workflow especially related to skeletal meshes and stuff but if i can't find a fix i'm sticking to 5.2

[cosmic kiln]

give the actors a triggerbox the player has to be in to "enable" interactivity?

is that doable

[steady night]

@frosty heron

[spark steppe]

it comes down to the same

[magic crown]

Well. Nothing really runs until they interact with it.

[spark steppe]

i don't think that some tree actors are their main problem

[magic crown]

It's just that apparently having so many actors in a level is very demanding, but there must be lightweight alternatives to have so many actors.

[cosmic kiln]

can't they use level streaming or something?

is there a reason why that can't be done to alleviate performance

[magic crown]

Actors are actors. They always exist, unless destroyed.

[cosmic kiln]

ah

[magic crown]

But yeah not to mention, using tree actors, that means each tree is a draw call. Yikes.

[spark steppe]

no

[magic crown]

Instancing ftw.

[cosmic kiln]

i'm aware 5.3 changed some things about the camera

added orthographic

[steady night]

@frosty heron ideas :/

[cosmic kiln]

but why's that break my shakes

[cosmic kiln]

and they can't merge them because they all need to be uniquely interactable

yikes

[magic crown]

Like said. It's all possible in Instanced Static Meshes. They just gotta figure it out

I keep hearing that the Devs behind the game had no experience before palworld with development.....

[frosty heron]

@steady night start to run out of ideas and this seems to be unrelated but try BlueprintType in the UClass macro in your header file

[sacred canyon]

ok Im already lost again

[cosmic kiln]

bruh

and they went straight for Pokemon ripoff?

[magic crown]

They knew what they were doing.

[sacred canyon]

they had money for marketplace

[dreamy elm]

How can i create async function in c++ and expose to blueprint? like a delegate with OnEnd event?

[frosty heron]

@steady night can you press Ctrl B to build and click on the play button afterward

[sacred canyon]

trying to call the damage function on a hit actor but now I have to idea how to reference specifically that actor because the only target input is the function itself (which is somehow "self"?)

[cosmic kiln]

not educated on what changes, other than adding orthographic support were made

[steady night]

@frosty heron can find any blueprinttype like that only "EBlueprinttype"

[cosmic kiln]

i can't see anything in the settings for the camera that could indicate some sort of difference in how shakes are done

[frosty heron]

Dont worry about the drop down, just type BlueprintType

[steady night]

k

[kind willow]

I'm trying to check whether the name of a bone ends with a specific word. Can I insert a wildcard into my equal check or is there a different way?

[steady night]

same error

[sacred canyon]

like how are you supposed to add the actor

[frosty heron]

@dreamy elm best to ask in #cpp , while I have no idea and they probably have the answer. If i have to guess, you can probably do async action with Laura's coroutine plugin

[cosmic kiln]

i believe this is a classic case of messing up the Blueprint Interface

check again that you implemented it correctly, it seems you need the right input

[keen ridge]

does anyone know of a way to slice a procedural mesh at runtime in a voronoi pattern?

[sacred canyon]

thats there by default

[cosmic kiln]

yeah cuz you didn't add anything i bet

you're meant to add the input you need it to be in the interface

like if you are trying to reference an actor, add an actor input

[sacred canyon]

yeah but THEN what

I tried that, and cant do anything else with it

because its just a variable input, not calling it on an actor

[frosty heron]

convert to string or text and use what function they have

imo

[cosmic kiln]

you plug the actor in there

[sacred canyon]

yeah it did nothing

[past compass]

You’re not calling the message and are calling it on the actor that has the interface instead of calling it from the hit actor ref

[cosmic kiln]

oh yeah i forgot you can mess up like that

yeah what he said

[sacred canyon]

oh my god, it was hiding the message option because of the context checkbox

[cosmic kiln]

i'm still waiting to see if anyone knows how to fix my camera.......

[sacred canyon]

ok thanks, that was the problem

[kind willow]

That'd slow down the game significantly, since strings are pretty hefty to compare, but I think I'll do that if I won't find a better way

[dry sleet]

colour me surprised...

[magic crown]

Yeah man..

[frosty heron]

it won't

try it on tick or w/e

you won't lose a frame

[noble ledge]

Is "Unknown" equal to nullptr?

[frosty heron]

afaik the watchlist is not that reliable

just print string imo

[noble ledge]

got it. thanks

[frosty heron]

if it's not valid then it's nullptr

[cosmic kiln]

"Post-process settings from camera shakes and camera animations are now handled as overrides, rather than base world values."

i'm unsure if this is related to my issue

found it in the 5.3 patch notes

"Refactored camera shakes' time management"

what the hell's that mean?

AHA I FIXED IT

the blend in timing was changed

i lowered it

now it works

[polar sphinx]

If I get an array by casting to the blueprint it's defined in, then editing that array, am I editing a local copy or the one in the blueprint in which it's defined?

[lofty rapids]

i believe the one in the bp, i have used variables where when i change them, they update in the bp

[polar sphinx]

Thanks, I think it's working. Not sure if marking the array as public was needed, but I did that as well. 🙂

[remote meteor]

you need to add Slate to your Build.cs as public dependency

just uncomment also works

[lofty rapids]

i usualy tick expose on spawn, instance editable

think instance editable is what you want in order to use it

[cyan jetty]

in debug Simulation nothing happens when i click on the Player (it should switch the camera to the player i clicked)

[frosty heron]

Don't use simulation?

[cyan jetty]

debug option

im new in UE5...

[frosty heron]

Select Play In editor instead simulate

in Simulation mode you are not attached to any character

hence if u have logic there, it's not gonna get called because u wont have a character

use Selected Viewport to start your game

[cyan jetty]

dosent work

[frosty heron]

you are still simulating

[cyan jetty]

i hav

[frosty heron]

then the next step is to ensure that your click event actually firing

you can print string to check if the event fired

[cyan jetty]

nope

[frosty heron]

well that will be a place to start then

[dry sleet]

You're just activating the camera component -- does that really make it the active view target?

I recall a node called Set View Target with Blend or something like that.

ah but if it doesn't fire then of course first attend to that

[surreal peak]

If the Actor is already the ViewTarget, it would instantly flip to the Active camera

[dry sleet]

gotcha

[surreal peak]

Otherwise it wouldn't have an effect

ViewTarget is the Actor

Camera is mainly an Offset to the code +- some visual stuff

[primal crown]

i feel stupid what could i be doing wrong im getting no overlapping actors? and yes my mesh is there that could i be doing wrong? does it matter if mesh is inverted lol "it shouldnt be visible anyway"

[flint vault]

I've setup a CharacterSelectMenu widget and having an issue. It requires a target, what should I target?
The logic for cpp:

void UCharacterSelectMenu::OnCharacterButtonClicked(int32 CharacterIndex)
{
    APlayerController* PlayerController = GetOwningPlayer<APlayerController>();

    if (PlayerController && CharacterIndex >= 0 && CharacterIndex < CharacterClasses.Num())
    {
        UClass* CharacterClass = CharacterClasses[CharacterIndex];
        if (CharacterClass)
        {
            FVector SpawnLocation = FVector::ZeroVector; // Set your spawn location
            FRotator SpawnRotation = FRotator::ZeroRotator; // Set your spawn rotation

            ADynaPrimeCharacter* NewCharacter = GetWorld()->SpawnActor<ADynaPrimeCharacter>(CharacterClass, SpawnLocation, SpawnRotation);
            if (NewCharacter)
            {
                PlayerController->Possess(NewCharacter);

                // Re-enable player input
                PlayerController->EnableInput(PlayerController);

                // Remove the widget from the viewport
                RemoveFromViewport();
            }
        }
    }
}

Any suggestions?

[edgy ingot]

@flint vault the target would be character select menu. W.e that is

[flint vault]

This blueprint (self) is not a CharacterSelectMenu, therefore ' Target ' must have a connection. @edgy ingot

[edgy ingot]

@flint vault yup thats what its saying

W.e blueprint you are in is not characterselectmenu thus you cant use self and must feed the target with a pointer to characterselectmenu

[flint vault]

That's odd, because it is that blueprint haha

[edgy ingot]

Look at the class at the top right

[flint vault]

User Widget. Oh so should I cast it maybe?

I'll remake the widget under that class. I get it now

[edgy ingot]

Just reparent it to your cpp widget

[flint vault]

Yes, I did that. Thank you

It works

[edgy ingot]

@flint vault go to class setting and select your cpp widget as the parent class

[remote meteor]

when you need to untick context sensetive to find your node, its time to doubt

sum ting wong

[frosty heron]

@remote meteor sorry to bother but I got this curiousity.

std::shared_ptr<Player> FrankShared{ new Player {"FrankShared", 33, 294842}};
std::cout << FrankShared->Name << " " << FrankShared->xp << std::endl;
*FrankShared = hero;

If my shared ptr points to another ptr, what happend to the object that was allocated when I create the shared ptr? Do I get a memory leak or does it get deleted automatically?

[remote meteor]

with a shared_ptr(TSharedPtr for unreal), the lifetime of that object is kinda managed, so it gets deleted automatically

with a raw pointer then you need to be more careful

[frosty heron]

Thank you

for raw cpp that's the case too I suppose?

[remote meteor]

i dont really know about smart pointer until i reach unreal, but yeah smart pointers are created mainly to solve these issues

they are kinda the same thing, just TSharedPtr has some unreal magicary wrapped on it

[frosty heron]

in cpp they get deleted automatically when out of scope and I can use .use_count() to check but if I change the pointer, I am not sure how to check anymore 🥹

[remote meteor]

im guessing std::shared_ptr and TSharedPtr are supposed to behave the same 🤔

[lusty hedge]

does anyone know what that museum like project on the marketplace is called

the one that shows examples of nearly every unreal mechanic

[zealous moth]

how would you make it so that when 2 pawn units touch each other, they can push each other by continuously walking?

[primal crown]

im really trying to understand overlapping actor because i cant get this to work it doesnt find anyactor or am i doing something wrong?
i want the triangle mesh to Detect stuff so cant really use a box collider

[frosty heron]

I would love to know this too 😭

[zealous moth]

I tried RVO and depenetration (not deep) and neither worked

[frosty heron]

just finished Nier Automata, gotta love the controls and how it pushed NPCs away from my path when i bump into them

[remote meteor]

pushing each other = apply force on collision

pushing only from 1 party = ignore actor when moving

[frosty heron]

🗒️

[sand yacht]

For anyone planning on making a big game someday... Make sure to keep track of your references so you dont end up with a memory load of 12 gigs

[frosty heron]

use soft reference

[sand yacht]

Yes I figured 😂 We're about to rebuild the entire game as this is just completely messed up

[obtuse mulch]

many of us been there

[zealous moth]

@frosty heron
I tried:

• CMC RVO
• CMC depenetration
• CMC physics force

But none seem to work :/

[frosty heron]

😔

maybe apply force ?

[zealous moth]

in cmc? it's enabled

[frosty heron]

make the player the boss that push everyone based on the direction he is going :D, I dunnoe

[zealous moth]

I want both

[frosty heron]

i mean, I have no idea. eventually I need to do the same thing

would really love to know how it's handled in big games

[zealous moth]

I'll keep working on it and update you @frosty heron , personally I am looking for a built-in solution otherwise it'd be a tick event on overlap but I really don't want to go that route

[frosty heron]

Thank you! I will appriciate the update 🙇‍♂️

[remote meteor]

onhit fires on every tick you move that collides

use that to apply force

[frosty heron]

[cosmic kiln]

how do i overlay a camera onto another camera?

like do a viewmodel on one camera

got no clue how to do that rn and i gotta do it so the FOV doesn't change the weapon position

[thin panther]

you don't get camera layers like that in unreal

[cosmic kiln]

ah ya don't? alright then what's a way i can make sure the FOV of the camera doesn't affect the weapon position?

[silk cosmos]

You would need to adjust the world offset position in the material I believe. I've always just copied one from a marketplace asset that I own so idk the ins and outs

[cosmic kiln]

.........what?

what material? what's a material got to do with this'

[silk cosmos]

You don't get camera layers in unreal. You can use a material to offset the mesh's position/size to handle FOV adjustment and overlay over other meshes

[noble brook]

Hey all, I am creating a designer placed camera system. We call the placement blueprint objects “camera nodes”. Then we have a camera node manager object that finds all camera nodes within its sphere collision and sorts this array of camera nodes by distance from pawns location.

Our goal is to place camera nodes around the world and have the cameras blend to each other based on the players position to them. I have tried many things but I think this is more math heavy than I am capable of working out. Any ideas?

My main thought is to find a value that represents closeness percentage to a target node by further sorting by distance and direction, then averaging the three nodes data with each other based on this alpha value. Again, I’m not sure how the math would work out though even if I’m right.

[cosmic kiln]

how the hell does a material do that?

materials wrap around meshes, how does it change a mesh's location?

that's not possible

[silk cosmos]

Same way you can use a material to bend grass with the "wind". World offset position. Search for fps/weapon clipping on YouTube. There's quite a few tutorials on it

[zealous moth]

@frosty heron the only way so far is to enable physics and give it a mass however this breaks any movement capability... maybe on hit, enable physics and slide it... still working on it

[frosty heron]

I don't think I can enable physics on my character 😭

[zealous moth]

you can lock the axes and enable friction for a bit

otherwise launch it

[marble yew]

Why view documentation is not clickable ?

Did i forgot to install something ? I just want clickable web link to docs.

[zealous moth]

@frosty heron nothing built in works, this is the only solution

[frosty heron]

Ty 👍

[faint pasture]

depends on how they're moving to begin with

[zealous moth]

it doesn't matter, the only way to make it work with physics AND CMC is this

[faint pasture]

I mean you said pawn so you left it open

my pawns use physics only so it just works

[neat lava]

How do I get reference for Character(Enemy_Charactor) which the AIController(Enemy_Controller) is Controlling, someone help please ?

[vapid edge]

i have a bp like dis with a sphere collision.....is there any way to remove the collision after the 3rd person char collides with it 1 time ? i feel im doing something wrong i can only destroy everything not just that 1 thing..as i want the audio and cube object to stay and not trigger anything after

[vestal sapphire]

You can do "Set Collision Enabled" node, and select "No collision"

[vapid edge]

thank you so much 🥺

[pliant kernel]

Anyone know if SaveGameObject arrays are meant to be specified in lenght? I have a working system, but the first run the amount of items I stick in the array defines the "cap", and I cannot stick any more items in the array on subsequent runs 🤨 🤧

[cosmic kiln]

alr thanks

[void flax]

Hey guys, I am trying to calculate the vertical angle between my character and my enemy, do know if is under him or not?
Any idea how to do that pleeaseee 🙂

[frosty heron]

What caps? pretty sure the caps is like millions of entries for array. Could be wrong tho on this

[pliant kernel]

the cap could be like 4 items in the array, whatever number I save into it the first time. When I run the game a second time I can only overwrite those 4, and not create new ones. If I created 20 on the first run, I can save into those 20...

[frosty heron]

wdym you can't create new ones 👀 , share your code

you can most deffinitly add and remove elements in array to your heart content

[pliant kernel]

yeah, that's what puzzels me. one sec

[frosty heron]

@pliant kernel what's the goal here?

you seems to set an array to it self a few times

when you want to add just use add node

and remove to remove

that will update the array

[frosty heron]

What's the goal here? do you want a fixed number of slots?

or player can just keep adding forever

[pliant kernel]

the reason I do it this way is that the save UI is populated from the array, with forEachLoop. And I wanted the items to appear in the same order as in the UI

yes, adding forever

[frosty heron]

Do you need to display the empty slots then? if you do, you need to determine the logic on how you want to display the empty slots

eg, adding 1 - 2 empty slots after displaying all current saved file

[pliant kernel]

I just add one extra (empty) slot if you are in save mode.

[frosty heron]

You should have a container that contain all the save data

which for obvious reason should be a save game object too because you need to retreieve that data

So I will have 2 Save Game Object class here.
One to hold all the save Game Files
And the other is the SaveGameFile for the game it self (the slots)

When you open your save Game widgets

1. Get SaveGameFiles -> For every slot, create widget and add to vertical box

2. On Completion, add N number of empty slots

[frosty heron]

you probably don't even need slot ID imo

[pliant kernel]

that's my current

[frosty heron]

the Slot ID will be the index number of the array

i mean , what happend when you have 24 slots. Numbered from 1 to 24 then suddenly u delete slot 3?

[pliant kernel]

the ID won't affect how they are added in the UI. so IDs can be missing

[frosty heron]

Get SaveGameFiles -> Get the Slot Widget Infos -> Populate the widget with it

[pliant kernel]

it's used for identification and to load other data. and I use that to find slots that have changed, and save to them

[pliant kernel]

yes

[frosty heron]

Whenever you add a new save game slot, just add it to the SlotWidgetInfo array in SaveGameFiles

You can use FGuid to give a unique ID for each slot

[latent ridge]

im having a bit of an issue you see i have two projectile actors both have the same parent actor. i program both actors to spawn different actors but for some reason only one of them is spawning but the other one is not. i thought i could use this blueprint and remake it in the other actor but its not working i have it connected to on component hit event and connected to other actor

[pliant kernel]

That's what I'm doing, no?

[frosty heron]

@latent ridge this part not gonna run because you destroyed the instance of w/e class u are in

[pliant kernel]

In the section "Event Update widget"

[frosty heron]

I would have 2 SaveGameObjects. One to contain all of the SaveGameSlot and one for the SaveGameSlot it self

btw I can't really read other ppl code, especially with only a screen shoot. just throwing ideas

[pliant kernel]

I don't understand that. just to clarify, I'm allways saving to the same "slot" in the save object, I never change that. My UI "slots" are, like you say, just created for each SlotWidgetInfo array item

[pliant kernel]

No worries, I apreciate you throwing them

[frosty heron]

@pliant kernel You are loading your .sav file so if you have 4 slots, there should be saveslot_1, save_slot2, save_slot3, save_slot4
And when you want to load slot 1, you load saveslot_1

[pliant kernel]

hmm I could do that, so actually using the slot function on the .sav instead. Then I can change the savegameobject to a single value instead of an array.

[frosty heron]

well I guess it depends on the design of your game

[pliant kernel]

but I won't have a handy array to make the UI from

[frosty heron]

for me, I just create a .sav file for every slot

UI job is just to read stuff

as long you have the data then it's easy

[latent ridge]

this one works for only the first actor, i want it to destroy the actor, sorry if im sounding confusing you see the cold is suppose to spawn one actor at a time which i applied into my projectile blueprint and sorry about that i thought it would be readable but i was trying to fit it all in the blueprint. i thought if i could recreate this same code in another projectile blueprint different from this one it could allow me to spawn a different actor but for some reason the actor isn't spawning at all.

[frosty heron]

This is my Save game, SGC is the save game collections, it contains all the name of the save slots. For every slot, I create a widget

[pliant kernel]

ah, so a new saveGameObject for every "UI slot"

[frosty heron]

for every SaveGameSlot, UI job is just to read

that;'s how I do mine anyway, i never have formal education

so not sure how others do it

[pliant kernel]

so you don't bother with this slot functionality right?

[frosty heron]

but it's all about reading data, you can ofc only use 1 SaveGameObject if you want

[frosty heron]

that's necessary to load the .sav file

I save and Load just the same

[pliant kernel]

oh, yes, but I mean you just stick the same in there, never change right?

[frosty heron]

Can't draw anything from those pic alone, sorry. Can you forget your bp for one sec and tell me what you want to happend

@pliant kernel kinda how i structure mine

SGC simply contain the name of the .sav files

[latent ridge]

ok sorry again for the confusion, i want to have two types of projectiles one that can spawn a block on impact the other can spawn a circle on impact both have a limited number of objects it can spawn at a time so the can't continuously spawn those objects the first one can spawn 6 if the spawn anymore than the oldest one in the list is destroyed while the second projectile can only spawn one at a time

[regal tapir]

right: bed bp
left: AI tress asset
I'm trying to make ai if I hide while he is chasing me and get to a box collision (yellow or blue) can throw me out. I made a interface in focuse and make event for interface in asset but not working what am I messing?
why my Interface not working?

[regal tapir]

Holy moly

[frosty heron]

are you trying to do object pooling or something?

[round grove]

Guys I need help trying to move a platform in an "U" shape. Essentially go some units in z axis, then some in x axis and finally another z axis movement.

I am using a timeline and I would like to be able to reverse that movement

[frosty heron]

If you want to destroy the oldest one, then you need to store those projectile in an array. Add to the array every time you create a projectile.
Then define when you want to do the check to destroy the oldest projectile in the array.

[lunar sleet]

What the heck is “ai tress asset” , and what’s in that player controller index? Is that a graphical artifact or did you put * in it

[frosty heron]

When ever you want to create the projectile, check the array size. If it already reach the number you want the max projectile to be, then don't spawn a new one

[pliant kernel]

Ah, thanks. I'll see if I can rework mine

[lunar sleet]

So use the reverse pin?

[round grove]

I cannot seem to get the same sequence in reverse

[regal tapir]

nice question I really dk put message target to where, I mean AI behavior tree asset

[lunar sleet]

Show code

[latent ridge]

that's what i thought i was doing in my blueprints but for some reason the second projectile the spawns the circle lets it spawn alright but the first projectile doesn't spawn at all and only spawns on top of the circle when its spawned into the game that is the issue im trying to solve

[lunar sleet]

That looks like a BT task. I’m confused as to why you’re trying to use an interface call from inside a task, what’s your goal here

[regal tapir]

I am making a horror game and I made AI chase and focuse on me if see me, I have hiding spots, I want If AI is chasing me and focuse on me and also while it is doing these things I hide, it can throw me out

[frosty heron]

if u are spawning them on the same location in a for loop, they are probably stacked againts each other or not spawning at all depending on the spawn rule

[lunar sleet]

You should go and watch the 4th pin video in the #gameplay-ai channel,

It teaches you how to actually use BTs properly

[round grove]

I get the foward sequence of what I want but using 3 timelines doesnt seem to be the most efficient

[lunar sleet]

You should only be using one

[regal tapir]

You mean this?
https://www.youtube.com/watch?v=iY1jnFvHgbE

ok tysm homie

[latent ridge]

it more like the square won't spawn anywhere else unless its on the circle

[round grove]

How do I go about using one to lerp between 2 sequenctial vectors and get a reverse sequence?

[lunar sleet]

I see exactly 0 lerps in your code

You’re using the track as a common denominator and just changing the factor by which they’re multiplied. Why not just swap and put those numbers all on the track

[warm cloak]

when calling DestroyActor() in BP, any references to that actor becomes invalid ?

[lunar sleet]

Yes

[warm cloak]

ty

[latent ridge]

thank you again for helping me out on it i was able to figure out what you meant and fixed the issue

[tropic peak]

okay I don't even know how these are called so I'm just gonna ask here. how do you make these

[edgy ingot]

Double click the line. Its called reroute node

[tropic peak]

ty

[austere ingot]

is there a way to get a static meshes nanite settings in blueprint?

trying to make a checker that will test if actorsbeing used have nanite enabled but cant seem to find a way to do it

[marble tusk]

Can also hold the R key and click the graph to place one without a wire

[round grove]

ia there a way to mask out points in a timeline that you dont want in the track?

[orchid pollen]

Hi ! I have a problem to give a parent reference to my entry utility widget. Self node give None and I don't know why

[astral geode]

Hi i have tried to make a settings page where you can change your resolution but when i tried it out in a standalone game it doesn't change it feel free to ping me if you know why this could be happening ty

[edgy ingot]

U didnt connect the apply

Afaik set resolution dont work in editor

Package the game and try there

You also have to make sure u r in full screen mode

I think there is full screen, windowed snd borderless window

Set resolution wont work if you are in borderless window iirc

Also instead doing it like that, make option that populate all supported screen resolution

[astral geode]

lemme try them out 1 sec

[edgy ingot]

Its 6 am here. Im gonna sleep. Do your best, if you cant figure it out, you can ping me. I will share my code

[astral geode]

oh alright thanks for helping

[tropic peak]

I want to simply rotate a mesh in Z axis using timelines, what node should I be looking at?

[molten yew]

Anyone know how to fix the buggy movement in the top down template. The one where if you walk behind something you character shakes and rotates. (I'm still in the navigation box, only happens when I try to walk behind something)

[warped juniper]

Hey, what are your suggestions for making an actor jump in a fixed arc?

I wanna create a pretty specific type of physics behaviour but using simple add force isn't helping

[lunar sleet]

Idk what you mean

[warped juniper]

I think they ask if there's a way to make it so X points in the timeline have a value of 0?

[lunar sleet]

Yeah insert a key frame and give it a value of 0

[warped juniper]

Could also do a simple code setup to override the current value to 0 at certain given values

[visual crest]

this is not launching the projection forward like I think it should. What am I doing wrong?

[versed sun]

I use a Function that lerps between 3 Vectors to animate a smooth arc movement
https://blueprintue.com/blueprint/auohmy61/

[warped juniper]

Ah, interesting... But that doesn't seem to use physics...

Like would it collide?

[versed sun]

you can stop the timer when a collision is detected

[hoary nest]

I have a section in a blueprint that adds all sphere components of the actor into an array. I thought it looked ugly so I tidied it up a bit. What do you guys think?

[versed sun]

Looks cool, if that's what your asking
Could be codded smoother/quicker

[hoary nest]

I felt like I was committing a war crime. I didn't know there was a make array node. I guess I'll use that one then. Thanks!

These are actually static mesh components so sadly I can't do the get component by class, or I would have to add a part that skips unnecessary static meshes

[versed sun]

I think we have all been there, doing things the long hard way before learning something better exists

[versed sun]

sure you can

how many sphere do you have in the actor? and what do they do ?

[hoary nest]

ahh, didn't think of checking the mesh. I was just thinking of doing a check using the name of the component which I wanted to avoid. Cheers!

There are 14 in total, and they are options that the user can select. I'm making a 3D UI. (One of the ovelapping box-sphere sets will be hidden)

[versed sun]

ahh cool

[celest island]

Anyone have any tips for stopping the overall scene lighting leaking through? I have inviisble walls that are working fine with direcitonal lights, , but there does seem to still be leakage with the level lighting. Feel like im missing something

[lunar sleet]

#lighting

[celest island]

oh ty

[warped juniper]

Do you reccomend using Components for making a Health system across actors?

I know it's a quite basic thing but I was wondering if that's the better practice

[lilac junco]

Hey everyone! Seeking resources for learning Advance Locomotion Systems for characters in Unreal Engine 5? I need step-by-step guides, starting from basics to advance. Any suggestions? 🤔

[leaden sparrow]

Hi all, I've got a fairly basic bit of Blueprint logic that has worked without issue up until this point, and I'm unsure why. The basic idea is when this moving wall hits the character they should die, however what is actually happening is they sort of just phase through the wall and nothing happens. There is an exception in that if the character is walking when they get hit with the wall they die, but not when standing still. I've tried remaking the wall, slowing the wall down, making the wall thicker, changing On Actor Hit to On Actor Begin Overlap, and nothing has worked. I'm extra confused as I've used a very similar process for my last two levels with no issue.

I want to add that I have not messed with collision settings it is just a cube that should kill the player if it comes into contact with the player

[fallow umbra]

Try using the debuger on On Actor Hit or just add a print right after the event and check the value for Other Actor

If you don't get anything while standing still, your character might be in "sleep mode" or how ever is called

[leaden sparrow]

No activity from the debugger

[fallow umbra]

Go your actor and click the Class Defaults search for sleep

and search for sleep in the details panel

here's an example from chaos vehicles, the 3rdPersonChar should have something similar

[leaden sparrow]

Got it, this seems neat but what would it be used for?

[fallow umbra]

I think the engine disables the tick for actors that are not moving or performing any logic

[leaden sparrow]

so i have a sleep threshold value for the mesh and the capsule component, set them both to zero but the problem is persisting

[fallow umbra]

Try to set the sleep family to custom

[leaden sparrow]

just did, same result

trying sensitive

still no luck

[fallow umbra]

in order to use the Custom Sleep Threshold Sleep family has to be on custom, perhaps try negative values? - to be hair I have no idea how it works and what's the proper way to prevent actors going to sleep

personally I manage to reduce it for chaos vehicles - but that doesn't apply to you

[leaden sparrow]

set it to -100 just to be silly and still not working

switched to custom too like you said

i also noticed its moving the player back before phasing through like its pushing him a foot backward

[fallow umbra]

Then I have no idea how to fix it unfortunately, just search more about character/actor sleep (or dormancy)

or perhaps someone that knows how to fix this will reply

[leaden sparrow]

thanks for your help anyway! had no idea this setting existed

[sour moat]

😳 What's the problem? It crashed when I was working and crashed again and again if I reopen it, but other projects do not have this issue.

[warped juniper]

Hey there, I have a question about arrays.
I have a camera with settings to control if it can rotate, and how. The array of booleans checks for locks on XYZ. However, for clarity when working, how can I make the array display the X Y and Z?

Instead of "Index"

[unkempt warren]

Do you have "Simulation Generate hits" checked in the details panel of your wall?

Also, why not do like a health damage type of deal then handle the player's death inside of the player?

[unkempt warren]

Its under collision

[leaden sparrow]

It's meant to be an instant kill, death logic is in the player but other actors can call the function

i'll try ticking generate overlap events and see what happens

still no luck

so the wall didnt have that hit events setting but the player does, tried ticking those and still nothing

[unkempt warren]

That's the wrong collision you want the wall itself selected in the actor bp when you look for generate hit events

[leaden sparrow]

Found it in the wall actor bp, ticked it and tested and still nothing

[unkempt warren]

Did you use print string to see what the actor is hitting?

[leaden sparrow]

just tried it with nothing being printed, but maybe i set it up wrong?

[unkempt warren]

Nothing is being printed at all?

That sounds like On Actor hit isn't even being called at all in that blueprint itself. How are you getting the On Actor Hit Event?

[leaden sparrow]

So as I said before, it will activate if my player is walking, I tested the printstring while i was walking and it printed the character bp, but if I'm standing still nothing happens

But to answer, i have the wall selected, then in the level bp I right click and get the On Hit Actor Event associated with the object

[wanton prism]

is someone able to help me?

[leaden sparrow]

i saw a response but its gone now

[unkempt warren]

Why would you do it in level BP?

I would do it in the Wall Actor itself.

[formal laurel]

Guys, can you tell me pls how to cast use interface from player controller to actor blueprint?

[unkempt warren]

Do "Remove UI (Message)"

might have to remove the "case sensitive" to find it

[leaden sparrow]

worked before, I'll try moving the logic to the wall actor

still not working

[unkempt warren]

Should have an evelope on it when you're talking to the Remove UI BPi

[formal laurel]

what need put in Target?

[leaden sparrow]

Try adding IsValid? before your branch

[formal laurel]

If I insert a reference from a blueprint into the target, how can I choose it in player controller?

[unkempt warren]

Can you show what you did in the Wall Actor bp itself

[leaden sparrow]

yea one sec

[formal laurel]

so many questions😅

[leaden sparrow]

I will note that I'm not sure I set it up right as every other time i've used on actor hit that bind even node never showed up but here it is

[wanton prism]

?

[unkempt warren]

That's binding events, you're going to want to select yuor wall in the bp and do "On Component hit"

[wanton prism]

for the cast? the cast works

Works fine here for some reason

[leaden sparrow]

Still nothing

[leaden sparrow]

so are you good or still getting errors?

[unkempt warren]

Weird.. Give me a second imma test it myself cause it should work..

Could you print string that though to see if its hitting stuff?

[leaden sparrow]

sure one sec

[unkempt warren]

Okay so mine works. So, there's something going on somewhere.

[leaden sparrow]

same deal, nothing when standing still, but when walking its working and printing that its hitting my character

[unkempt warren]

Does the wall move?

[wanton prism]

no the othere one is difernt code idk why it isnt working it for a differnt system being used in the same area for the puzzels

[leaden sparrow]

the wall is the only thing that should be moving

[unkempt warren]

How are you moving it?

[leaden sparrow]

in a level sequence

keyframes

[leaden sparrow]

would you be able to hop in fort fivus so i'm not flooding this with the same problem

[wanton prism]

fixxed now i just ripped the code from the other puzzel

[edgy ingot]

@astral geode u packaged the game and test?

[earnest vigil]

Hey it looks like my print string nodes have stopped working? I dont remember changing anything from today to yesterday that would have disabled them. It is all of them not just certain ones. Any ideas?

[warped juniper]

Hey there.
How can I up a boolean that returns true, if the overlapping actors of a component do NOT have a specific tag?

I'm using the GetOverlappingActors array for this.

[edgy ingot]

Are u in development mode? Did you type disable all screen messages?

[edgy ingot]

Get the actor, get the components, find tag

[warped juniper]

I'm using an array of actors though

[edgy ingot]

Tag is just an fname isnt it, pretty sure there is .find

[warped juniper]

The tags are part f the actor itself

[edgy ingot]

Dont matter

Sure, whats the problem?

[warped juniper]

Yeah but when I type tag from actor it doesn't show anything

[edgy ingot]

U get the actor then u get the actor components

Well depend where u place the tag

Just show some pic

Where do u add the tag

[warped juniper]

The tag is placed on the root

[edgy ingot]

So actor has tag then

[warped juniper]

Yeah

[edgy ingot]

Thats the node u can use

Loop thru the actor, for each of the actor check if they have the tag

[warped juniper]

Yeah I tried that

But that makes it so the last actor in the array is the only one that matters

[edgy ingot]

Show some code

U r doing it wrong

What u want to do is trivial

[warped juniper]

Of course I am doing it wrong

I'm a non coder doing code out of need

[edgy ingot]

K what do u actually want to do here

[warped juniper]

Whenever the collider ends overlap with another component, it checks all currently overlapping actors for the "pickup" tag

If there are no pickups, then it closes the Interface function I'm using to manage pickups

[edgy ingot]

Make a function call it CheckIfThereIsAnyPickupTag

It will return a bool value

In the function you want to get the overlapping actor and loop thru them

If actor has tag is true, return true right away

On completed return false

U can then use this function to check if there is an actor that have the tag in the pickup collider

[warped juniper]

Alright sounds simple enough

How do I make it return true immediatly and stop checking once it finds a true?

Just use a branch?

[edgy ingot]

In the loop do the branch check

If true return true. If false do nothing

The conditon being if the actor has the tag

[warped juniper]

Got it

Thank you for that

Wait a moment...

I feel so, so dumb

I could have just used a class filter...

[edgy ingot]

Depend on your purpose

[earnest vigil]

I think the issue was just some jank where I needed to restart

Thank you though

I do have another question though

I am trying to calculate velocity without using Physics and this is what I have come up with.

Event tick handles movement and the amount of time the actor has been alive and CalcVel is called onBeginPlay to spit out a velocity every second or so

It seems like this is pretty close but the issue is that the actor is always moving at the same speed but I am always getting a slightly different velocity when calculating

If anyone has any ideas it would be a massive help. Physics objects not being affected by time dilation has put me in a very annoying situation

[edgy ingot]

@earnest vigil pretty sure physic object are effected by time dilation?

Should be able to play around in template object with those blue physich boxes

[earnest vigil]

Sorry they are unaffected by custom time dilation

only global works

[edgy ingot]

Ye global will work

[earnest vigil]

I unfortunately cant use global since that affects much more than I have access to

[edgy ingot]

U can do custom time dilation on individual actor

[earnest vigil]

Yes, but I need to be able to use the movie render queue at runtime which is also affected by global time dilation

I dont believe I can change the time dilation for that though

[edgy ingot]

Well i never tried custom time dilation with physich object. Make it a bp actor and apply time dilation?

[earnest vigil]

It just doesnt do anything to a physics actor

[edgy ingot]

Well i never try so i dunnoe

[earnest vigil]

it is totally unaffected by custom dilation

oh wait

I think I see what you mean let me try that

[edgy ingot]

K googled it, u cant used custom time dilation for physich object

@earnest vigil

I think your only option is to do global and set custom dilation for things that shouldnt be affected or affected less

[earnest vigil]

Any ideas on the code I posted up top that I have to calculate the velocity?

[edgy ingot]

I cant do math soz

[earnest vigil]

All good thank you for trying 🙂

[edgy ingot]

My question is why dont u calculate velocity every frame tho

Delay there seems fishy imo

[lunar sleet]

Delay is almost always fishy tho tbh 😀

Btw we have #game-math for these questions now @earnest vigil

Where the scientists in the server live

[earnest vigil]

Oh thank you so much

I actually didnt have access to that channel before haha

[earnest vigil]

Without the short delay between when it gets the first and second point they will always be the same resulting in 0 every time. The second delay is only there so i only see it every second because it gets cluttered

[celest lotus]

is there any way to activate and deactivate Event Tick?

Like im making a game that has multiple levels, so in one level the character needs event tick to line trace and in other level it doesnt and its being a bother in that level so how can i solve this

[iron kindle]

has anyone seen any information about making quake movement like slash from quake champions ?\

[edgy ingot]

Set actor tick enabled

[celest lotus]

can i set that through game mode?

[edgy ingot]

Anywhere ur heart desire as long u have a ref to the actor

Assuming single player anyway

[main lake]

Is it normal when I run forward it runs smooth, but when running sideways or backward it start jittering (using the Third Person Template) ? https://gyazo.com/d3c66f480fdc231630d57a4c96cd7449.mp4

[edgy ingot]

Thats not how the template roll, u must have changed something

[celest lotus]

yep

[edgy ingot]

And no u shouldnt get any jittering with template

[main lake]

like what ?

[edgy ingot]

Thats not how the third person template even walk

I dunnoe what u did but theres no jitter for me if i start a fresh ,3rd person template

[celest lotus]

when move right the character will face the right

[edgy ingot]

Do you set something with replicated variable?

[main lake]

1 thing I remember changing what the "Use Controller Rotation Yaw" and check to "true".

[celest lotus]

u probably accidentally turned this off

[main lake]

nope that's still ON

[celest lotus]

show ur settings

[main lake]

it's too long, what part do you want to see ?

[edgy ingot]

I can only share my experience with 3rd person template. It doesnt jitter

[celest lotus]

this is how it works

[main lake]

Try to check "Use Controller Rotation" to see if does that issue

[main lake]

Wait that's not the Root component, which component is that ?

[celest lotus]

camera boon

[celest lotus]

set pawn control rotation on

this with the orient rotation to movement off

[main lake]

Where is "Orient rotation to movement" setting ?

[celest lotus]

character movement

[celest lotus]

this one

[main lake]

Problem solved, thank you 🙏

But I'm not sure to understand what was the issue in the first place 🤣

[celest lotus]

how it got solved?

[main lake]

I unchecked "Orient Rotation to Movement" on the Character Movement

[celest lotus]

oh

[austere patrol]

Hello, I want to know how people switch input.
For example when player open inventory widget, I want player to control inventory with arrow key.
For now, I wrote a Enum to switch right after InputAction, but it doesn't seems effecient.

[untold fossil]

hello. Does anyone know why the mesh in a character actor always resets to face a certain direction on non local clients? Everytime I move the mesh points towards the north for example. No matter what I do it always seems to override the rotation even when detaching the mesh on runtime from the character it still always rotates to the north. It's like the mesh is hardreferenced inside the character movement component or something and it's rotation is forced somehow? How can I disable this?

[celest lotus]

u prolly changed something accidentally im sure cuz its the other way around but whatever as long ur problem is solved it doesnt matter💀

[unkempt warren]

Create a demo thirdperosn template and copy camera settings from it.. Then change accordingly.

[olive yarrow]

So i've whipped up an inventory system buuuuuut every time i pick up a new item it overwrites the old item - so essentially i can only hold one item at a time...
Could someone help point to where i've messed up this blueprint?

[steady night]

how can this happen ?

in the Bp the candle is placed corrently but when i place it in the world

its offsett is insane ?

[versed sun]

is the Scale of the table or actor changed?

[steady night]

no

its so weird

[lusty shard]

make sure that the candles and paper within the table bp are using the same global or absolute location values

[lusty shard]

also try setting location to 0 for the "Doodas"

[steady night]

they are

[lusty shard]

they are what?

[steady night]

but i can set them to 0 then all of them would be ontop of eachotehr

[lusty shard]

would they be on the table though?

ooooh might be an issue in the world.. try dragging the table into the level again from the content browser

[steady night]

nah same problem i can put the table anywhere in the world but the candels are always spawned at that location O.o

[lusty shard]

oh really.. so no matter where you move the table the candles stay at the spot?

[steady night]

oh wait

i changed it from static to movable

cant have a child thats static on a movable object

then it moved

[lusty shard]

didnt know that

cool

so when you moved the table, you were getting warnings?

[steady night]

yeah since it was static then i couldent attach so be dufault got put in 0,0,0 i guess

nope

thats the thing

weird

[lusty shard]

very

[dark drum]

Can anyone think of any reason why adding a break point to a node (When debugging an issue) would actually fix the issue. o.O With the break point what should happen happens, if I remove the break point, it doesn't happen so I'm a little confused.

[lyric quiver]

Quick question, what does the default pin do here?

[dark drum]

I did find the bug to fix it but it was in a different BP. Just thought it was odd.

[lyric quiver]

k thanks

[dark drum]

I know what you mean, it doesn't happen very often for me but I've found its more likely to happen if I click and then drag instantly. Possibly a delay with it detecting the contents of the comment box.

Yea, just slow down, take it steady 😛

[hollow tendon]

why? not in scope just 1 node away

[tropic peak]

I have a platform blueprint, and in the hierarchy I have added 4 light blueprints on top of the platform. The light blueprint has some variables I would like to access, when triggering events in the platform blueprint - I want the lights to be switched on. Is this the right way of putting it together (parent-children components in platform BP), and how can I access the lights BP variables?

[thorny forge]

Hey guys, I'm a bit new to programming and I'm looking to see if there's a way to check "if any of these are true, proceed"

I've tried these two methods but they seem to rely on all of the objects being true or valid

Does anyone know a better way please?

I'm essentially trying to cut out all the errors I keep getting about accessing none because depending on which trigger I overlap, only some of the public fields have a reference in them and the others do not. Which returns an 'accessed' non error everytime

I was thinking maybe if there's some kind of 'AND/OR' condition I could use

[edgy ingot]

Or means if any of the condition is true, it will return true

So just do an or and add pins as needed

Then do a branch

[thorny forge]

ohh right ofcourse!

thank you

[hollow tendon]

Help

[hollow tendon]

.

[supple dome]

the unfortunate answer is that that is how it is

[steady night]

hmm im openineg my level from main menu level, as a presisten level how would i normaly put a loadingscreen inbetween there or how do you normaly do that stuff ?

tips ?

[edgy ingot]

Since you are doing multiplayer you can do a server travel once u are in the game.

But from main menu and when you open a level as a listen server, thats when a hard travel happend and there is no way around it

If u want a fake loading screen you can just slab a widget with static image. Add delay and start opening a level

[steady night]

aye that was my idea

[edgy ingot]

If you want a real loading screen then you have to use cpp

[steady night]

a fake one will surfice

hmm i think i know what to do

[subtle nova]

Hopefully quick question. I'm trying to have a BP listen to all my turrets and fail the player if they alert any of the turrets. Apparently you can't bind an event to a delegate in a For-Each loop though. It'll only apply one time.
Alternative ways??? Any suggestions?

[brisk rain]

Hello! I'm new here, why does this cast not work? It outputs no cast every time.

[hollow cove]

you can bind on a for loop. i've done it before with an array of buttons in a widget. something else is probably going wrong here

[edgy ingot]

You are getting a random actor from the world, it could be anything

[subtle nova]

Hmmm, I guess I'll keep digging then

[hollow cove]

have you checked the length of the array

[edgy ingot]

Get actor of class then chose your spawner class. U dont even need cast here

[brisk rain]

oh

alright thx

[edgy ingot]

Casting is just a type check. And the object feed to it needs to derived to what ever type your cadting to

[subtle nova]

Yeah, it's picking up all the turrets

[edgy ingot]

You can bind delegates with for loop. Doesnt really matter where u do it actually

[subtle nova]

hmmm, that's what I had thought, but it isn't working. So I guess somethign else is going wrong.

[edgy ingot]

Done it plenty of times with or without for loop

Print string the ref returned from your interface

Thats not even the right node afaik

Should get the one with the message icon

[subtle nova]

I've tried four different ways of accessing the alert component on the turrets to bind to the delegate. Consistently, only one (the same one) of the 9 turrets gets triggered.

Even though it's detecting all the turrets, and running through the for-each loop 9 times

[edgy ingot]

@subtle nova use the one with message icon. Then figure out how you set the return value

Clearly doing something wrong

Perhaps using things like get actor of class

[stuck dragon]

Hey guys, anyone know how to see if a side of an object is empty? For example on this I want to place an object on the left and right ends any methods?

[edgy ingot]

If this box r made from array then you can just check the index

[stuck dragon]

I was going to make an array, but I want this to be generated without any input so I want a way to check for the ends if that makes sense

[edgy ingot]

Many way to check, ur game ur choice

Think in plain english on how you can check if there is a box next to the box

One way you can check is doing a collision check

Project a box collision on each side of the box then check if there is the box collide with your cube

[stuck dragon]

thank you, i'll try this and see how it works.

[warm lava]

is there a simple way to check if a system file exists in the project folder

[frosty heron]

A system file in the project folder? like what for example

[warm lava]

need to see if this file exists: "K:/Drive/Whatever/UE/Project/Content/MDL/Functions/TEMPLATE.uasset"

[frosty heron]

@warm lava You can use File exist node but how does that gonna work in package

u won't see your typical uasset in shipping build

This to check if a file exist

[warm lava]

its for inhouse production, all editor stuff

[frosty heron]

ahh ok that's fine then

[warm lava]

thank you!

[frosty heron]

@warm lava if you need path to your project folder use get project file path

[warm lava]

thanks! I was able to get that far from previous help

[coarse grove]

Hello guys, Im looking to do an area damage around the player with some explosions, but I want to control exactly the distance from player each explosion will spawn. What would be the best approach to do it?
I was thinking to get forward vector and multiply by a distance, then rotate it around player, is there a better solution?

[hidden cape]

hey guys, not sure where to ask this...so just gonna ask here.. anyone know of any tutorials about using data assets for characters? I was told to add to my character for easy integration with different skeletons or something.

[steady night]

when i enter the game there is a brief 1-2 frames where it shows im guessing 0,0 point of the map before my Widgets are loaded in this case (loadingscreen) widget

is there a way to change where that screen will be :/ ?

[frosty heron]

@steady night for hard travel, u can't keep widget alive using BP

[steady night]

yeah i know

but its creating upon start

[frosty heron]

but you can with CPP :S

[steady night]

i jsujt want that first frame to be elsewhere

[frosty heron]

it's worth learning it

[steady night]

aye in time 😛

[frosty heron]

My loading screen always exist until the player character is possesed and ready to play

So I don't get to see the world origin even when im playing with lag

[steady night]

hmm yeah thats what i want obvi but its not the focus rn

i just want it fairly ok :/
