blueprint

[shell rivet]

but which should i choose?

emmmm, it crashed with defaults?

[orchid garden]

you can set all these in your class1 file so that they are defaults for class1:

[dark crow]

For example let's say you use ThirdPersonCharacter as your pawn when you play, in this case you would have ThirdPersonCharacter in Default Pawn Class instead of DefaultPawn

[shell rivet]

now, it's even worse

[dark crow]

You're trying to access the Candy but it's pending kill aka being destroyed

Probs from another actor

[orchid garden]

for instance, mine uses a custom character, MasterCharacter for the player pawn, so its setup like:

[dark crow]

So you're trying to Destroy the Candy from your Character?

[shell rivet]

how tf i make something like this?

here's the code of "candy"

[dark crow]

I personally don't suggest making other BPs handle something that itself should do

Like i would not want my Candy to be destroyed by the Character

But the Candy to have its own events to destroy itself under certain conditions

Even for organization sake

[shell rivet]

can you help me on pv?

with this?

@dark crow

[odd ember]

careful or you might incur the wrath of @torn kettle

apparently he's on the prowl today

[dark crow]

Well, the error seems to happen in the Character, not Candy

I think you're calling DestroyActor on the Candy from the Character when it's already destroying itself

[shell rivet]

there are only 2 things in character

[odd ember]

you're destroying your candy from your character though

[dark crow]

So it's being double destroyed

You don't need destroy in the Character

[shell rivet]

can one of you two help me on priv with that?

[dark crow]

Literally just delete Destroy Actor

In there

[odd ember]

I also see an OpenLevel node in the candy, I would strongly recommend to move that to game mode

[shell rivet]

but after several candy's touches the ground, the game crashes

[odd ember]

might have to do with OpenLevel being there

[shell rivet]

and it doesn't prints the "fail" string instead of hello

[dark crow]

Open Level is None

What is it opening?

[shell rivet]

menu

I'M DUMB

[dark crow]

Is your menu called None?

Cause yeah

That opens nothing

[shell rivet]

i didn't wrote the name of the level

• facepalm *

[dark crow]

It probs was messing with the GameMode too

Since it's Level specific if you Override

[odd ember]

again I would strongly encourage to move the OpenLevel node to your game mode

it's why you were crashing before

[dark crow]

If you want your GameMode to be the same in ALL levels

[shell rivet]

but when player touches 5 candy's, it still shows the game over screen

[dark crow]

Edit -> Project Settings -> Project -> Maps & Modes -> Default GameMode

[odd ember]

in your candy

your logic only executes when it hits a GameMode actor

[shell rivet]

do i set it to "class1"

?

[dark crow]

I think he's just accessing GameMode cause he has a variable in there that keeps stored the number of Candies that touch the ground

And yeh, if you want that to be the default for all Levels

[odd ember]

so basically

your counter increases

any time your candy hits anything

[shell rivet]

btw i store points in player

[odd ember]

including the floor

[dark crow]

That seems more like the collected candies

[shell rivet]

should i store them somewhere

[dark crow]

Than fallen candies

[shell rivet]

yes

where should i store them?

[odd ember]

you should gate off your candy collection

to only be done by your player

so before casting to gamemode

make a cast detecting which actor is overlapping

[shell rivet]

in candy

[odd ember]

yes

[shell rivet]

to who?

[odd ember]

whatever your player character bluepritn is called

[shell rivet]

and when it didnt casts, then cast to class1?

[odd ember]

is your character a game mode?

I don't think your character is a game mode

[shell rivet]

no

[odd ember]

so why are you casting to game mode

[shell rivet]

changed

[odd ember]

consider the actions you want to have happen

if your candy overlaps anything else but your character

you want nothing to happen

so if the cast fails, you do nothing

[dark crow]

You could have everything handled by the Candy too

If it overlaps and the cast fails means it's not a character so add one to Floor Touches
If it overlaps and the cast succeeds means it's the character so add a point

[shell rivet]

should it look like this?

[dark crow]

You gotta be careful with the logic

[odd ember]

yes

[orchid garden]

from my understanding if 5 hit the floor he wants the game to end

[dark crow]

You know how your games works

[shell rivet]

yes, to change the world to game over

or show the game over UI

[odd ember]

I see

[orchid garden]

game over ui would probably be a better option. you could setup retry button or quit button from that.

[odd ember]

I'd make a trigger box at floor level that eats coins

and increments a counter for each coin it eats

[shell rivet]

so...now what?

[odd ember]

well now test if your player collects 5 coins it wins the game

that part should be done

the fail condition you can make in any number of ways but I would not make that logic on the coin itself

or candy or whatever

[shell rivet]

i don't want the player can get maximally 5 points

[odd ember]

I dont understand what you mean by that

[dark crow]

Fail condition is if 5 candies hit the ground

[odd ember]

rihgt

[dark crow]

If 5 candies never hit the ground, the game will never end

[odd ember]

so what's the win condition

[dark crow]

Not losing i imagine

Lmao

[shell rivet]

there is no win condition

[dark crow]

You're a winner till you're a loser

[shell rivet]

you just need to get as high score as you can

[odd ember]

lol

[shell rivet]

y e s

[odd ember]

well like I said a trigger box is probably your best bet because it gives you the most control. I'd have as little logic in the candy as possible because it's an easy way to cause your game to crash... as you've seen

but if you want, you can remove the first cast again and that should work

[shell rivet]

which one? the selected?

[odd ember]

yes

[shell rivet]

or, can we do this "from start" again?

[gusty cypress]

sorry

[wide remnant]

In my opinion he is in the right channel

[gritty elm]

the sphere trace isn't hitting landscape, how to fix this

also event on landed not working

in character class

[amber marsh]

What would math would I need to do to make it so I ca get a weapon to do X damage per second regardless of its delay?

So if I want 5 different guns to do 10 damage per second. But each of them can have different rates of fire

[gusty cypress]

I have an event on begin overlap for a static mesh, when it overlaps I print "overlap" but it prints enough times to fill the screen, I even added a do once node to the event print and still fills my screen, should this be a concern?

[tight schooner]

@amber marsh 10 * duration of shot. So if it shoots once per second, it's 10 * 1. If it shoots twice, it's 10 * 0.5

@gusty cypress yeah it sounds like something is wrong

[odd ember]

sounds strange to say the least

[gusty cypress]

@tight schooner only thing I can think of is the trigger is a static mesh originally and not a trigger box maybe causing it?

[odd ember]

it could be if you're using complex collision

try using simplified collision shape components

[gusty cypress]

1 moment

@odd ember doest work unless its complex as simple, there are various triggers within my static mesh anything but complex doesnt properly work

[odd ember]

what i mean is use a simple collision component. using complex as simple is probably why you're experiencing issues here

[gusty cypress]

you mean not using my static mesh and instead using a different trigger

[tight schooner]

The thing about "complex" collision is each triangle in the mesh becomes a thin-walled collider... there's no concept of interior/exterior IIRC

so using that for overlaps can be kind of weird

[odd ember]

yeah

whereas simple collision is a math construct

[gusty cypress]

could adding a do once to my event solve this?

[odd ember]

unlikely

[gusty cypress]

darn

[odd ember]

why are you insisting on using complex collision like this though

it's like trying to fit a square peg through a round hole

[gusty cypress]

I've fully modeled the map including triggers and everything is perfect, going to each trigger and painfully sizing them to be similar as exact would be near impossible

[odd ember]

why would they need to be painfully exact?

[gusty cypress]

you're right but still an alternative would be easier as theres like 34+ triggers on my map and they are 2 static meshes making it much easier to work with

[tight schooner]

... you have 34 triggers but in two actor instances?

[gusty cypress]

yea... is that insane

[tight schooner]

normally each trigger would be its own actor instance

[gusty cypress]

I mean its worked great for me so far

[tight schooner]

does it all trigger the same thing? I don't get how it works

[odd ember]

sounds completely unnecessary

[gusty cypress]

sure, the game is a platformer with different stages. Each stage as a floor trigger if the player falls and it calls "stageFail" which resets the player. There is also a door trigger which calls "nextStage" and spawns the player at the next stage. I think this has made it vastly easier as theres not a bunch of individual triggers but 2 "doors" and "floors" and the secret to it working is when the "door" is triggered it adds 1 to current stage, then a switch on int allows for the new spawn.

so essentially two triggers with 2 call events vs 34 triggers

[odd ember]

considering you could copy paste the triggers and their logic this doesn't sound ideal

[tight schooner]

did you do it that way because you're doing level design within some external 3D package? (Blender etc.)

I mean yeah, it's not the normal or ideal way to do triggers but I'm just asking

btw if you want to define simple colliders within your modeling software, it's possible https://docs.unrealengine.com/en-US/WorkingWithContent/Importing/FBX/StaticMeshes/index.html#collision

but otherwise doing the level design within the UE4 editor -- placing 34 triggers and whatnot -- is the normal way

[odd ember]

I mean I do whiteboxes via blender and import them, still using UE4's native colliders for triggers

[hearty gazelle]

Is there a specific node that allows an actor to go in an arc?

Like a parabola movement

[tight schooner]

Sine?

Get Time Seconds into Sine

will produce a -1 to +1 wave over time

[odd ember]

suggest arc velocity or some such exists

[gusty cypress]

Used blender, will look into change collision there

[gritty elm]

is there anyway to change the skeletal mesh pivot point?

or adding scene component to skeletal mesh

[static charm]

ue4 has new modeling tools that let u edit pivots

but not sure its for skeletal mesh yet, might only be static mesh only

[gritty elm]

because when i rotate skeletal, the center point doesn't correct

[static charm]

but yes you can add a scene component and then move the skeletal mesh under it

[gritty elm]

it doesn't works

[static charm]

okay

add a new mesh to a new scene compoennt

and then make that old mesh blank/none

(its locked because it's a character class meaning it has predfined component list)

[gritty elm]

@static charm can i send you video?

here is this issue that i have

when i try to change pitch or yaw value, it doesn't rotate from center point

anyone can help appreciated

[static charm]

yes so once u have it put under the scene component, move the mesh so that the mesh is centered on the scene component

then you have to rotate the scene component to adjust the mesh

its a hack/trick lol

[trim matrix]

Please, what the node "Remove from Parent" does exactly ? I don't understand... I understand it is for removing a widget but I don't understand what widget it aims exactly...

[static charm]

It basically destroys/removes the widget from the screen

if you call the node inside the Widget's graph, it will remove that widget.

If you call the node in some other blueprint, you need to plug in a widget reference in order to remove that widget

[gritty elm]

thanks from help

[fair magnet]

So... If I use 1 Actor compoments which stores lets say health and 2 identical actors and I wanna use a blueprint interface to get Health from Actor B but not from Actor A how would I achieve that ?

[trim matrix]

@static charm Thanks. I think it's exactly what I did but it does'nt work 🙁 I have created in my GameMode BP, on a begin play event : a "create widget" node (which call "IntroLMDB" - see below) then "add it to the viewport". In the "IntroLMDB" widget, I did this (in short : the widget plays a video and when the video is end, I close the video with the widget :

But at the end, the media is still on the viewport and stucked on its last image

[orchid garden]

get a reference to the actor, then get a reference to the component attached to that actor that stores the health and then get or set the health variable.

[fair magnet]

but how would I get a reference then... I can't just use a variable or smth like that since it would get the other actors aswell :o

[trim matrix]

@static charm Though, the "Remove from Parent" is in the widget BP that I want remove. So... I don't know...

[static charm]

Lafourmi, you can try using Destroy Component or whatever node its called

[orchid garden]

@fair magnet that would depend on what your doing.

[fair magnet]

These Actors are supposed to be characters

[trim matrix]

@static charm Thanks. I'm gonna try this (UE just crashed btw 😆 )

[orchid garden]

@fair magnet let me rephrase... for what reason are you trying to get the health value?

[fair magnet]

Well to deal damage heal... all that stuff :o

[orchid garden]

so im guessing your using a line trace or sphere collision to detect the actor your attempting to damage / heal?

[fair magnet]

That's the plan

and I prefer using Blueprint interfaces since casts are pretty performance heavy

[static charm]

https://www.youtube.com/watch?v=G_hLUkm7v44

this 5 minute video might answer ur questions

[trim matrix]

The more weird is that I did it in the Level Blueprint just before (the code I put in the GameMode ("create widget" and "add to viewport") and those I put in the widget, were all grouped in the Level Blueprint) and it worked 🤔

So it looks like Level Blueprint works better for this... But really I don't know...

[orchid garden]

@fair magnet if your going to use a interface to heal a actor you'll just need to pass the information for the heal / damage process via the interface then handle the healing / damage on the receiving actor.

if its a multiplayer game - you should do the heal check on the server then run a multicast to update the effected players health.

heal/damage

[fair magnet]

I usually use RepNotifys to do that :o But thanks anyway ^-^Appreciate it

[prime wyvern]

Made my first ever BP

it's a bit shit to say the least

but it partially works

[static charm]

congrats

lets get you fixed up

[prime wyvern]

I tried to make it sweep (slide? I think its supposed to slide if it sweeps) but I have no clue what I'd have to create in order to get it to work

Any recommendations on how to improve the BP? (Please explain in simpleton terms as I'm no too smart when it comes to BP stuff, I once thought you could have infinite Event Ticks)

It's supposed to be a slow sliding door

[static charm]

So there's a bunch of ways of doing this.

do you want the door to close?

[prime wyvern]

not really

just want it to open

[static charm]

well i would just use a Timeline

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Timelines/Examples/OpeningDoors/index.html

you don't need the Reverse part

[prime wyvern]

ok

[static charm]

To explain a ltitle, basically Begin Play is only called/fired once.

so thats why the block just moved up all at once for you.

[prime wyvern]

oh

so would I have to use something like an Event Tick's Delta or something such as that to allow for slow movement?

[static charm]

Event Tick is called/fired every frame, so 60 times a second!

i suggest a Timeline here because it's Update output pin on the right side is basically a Ticking function and constantly updates for the length of time you select inside the timeline and then stops at your predetermined value/time.

if you use only Event Tick to move the door, then you have to fiqure out when/how to stop it, otherwise it will keep moving up.

[trim matrix]

The only "destroy whatever" nodes I have are these :

🤔

( I am in a widget BP )

[static charm]

I guess Destory is for outside the widget only.

But yeah Remove from Parent should be working

you can try asking in the UMG chat

[trim matrix]

Nope, Remove from Parent doesn't work 🙁

Ok, I'm gonna there 😉

[ornate cairn]

Hey, is there a way to make a physics object act as a non physics object to another physics object? In my project you can pick up physics objects and move them around and drop them. The problem is you can hit and move other physics objects with the item in your hand. Is there a way to make it so that if you hit another physics object, that one doesnt get affected?

[static charm]

well you can make them overlap and not block eachother

in the collision settings

but then those objects wont be able to interact

unless you only make it temporary while you're handling said object

like change it's collision profile or whatever while handling it

[dreamy ice]

do most people not use a full player model in first person and just show arms for the client

[ornate cairn]

the problem is if they are overlapping once you release the object it like clips out, which is kind of a problem

[static charm]

yeah you would change it back when releasing.

Nash, depends on the game. Some do full body and zero out the head/hide it. Some do arms only because they don't need or want feet.

[dense tulip]

is it possible to reorder variables in the Variables section of a blueprint ?

[odd ember]

yeah you can just drag them around

[dreamy ice]

Okay thanks 🙂

@static charm To do the hands my actor would need to consist of hands and a player model correct?

[static charm]

not really sure what you're asking. but it might be easier to just follow along a First Person Tutorial for UE4

[ornate cairn]

i know, what i mean is that if you set collision to block while they are inside each other wierd stuff happens

[static charm]

then you'll either need to add a check if it's overlapping an object and offset it before turning it back on. or maybe turn off physics for all objects near the object you're holding

like an overlap sphere 3x bigger than the object you're holding, and on sphere overlap, turn off physics for objects you're not holding, then on end overlap, turn physics back on.

[snow halo]

hmm, thought i was losing my mind, but not i'm just perplexed. I have a circle of instant static meshes and i'm using a look at rotation so their face faces the center:

works perfectly in blueprint viewport

in editor level viewport, wtf:

all my rotation happens in the construction script

what in da world goin on?

something must be using world space, just not sure what ...

im dumb, i fixed

[static charm]

the world view looks cool though

[radiant ore]

I want to make this puzzle with blueprint

Can I have some advices or how to do it?

[neat frost]

@radiant ore I would suggest storing piece data in some sort of structure

And having each puzzle be a structure that contains something like it’s dimensions

With triangles, it would be more complex

I hope this helps

😉

[amber sand]

How can I detect when an object(using Apex Destruction) has been shattered?

[upper linden]

i need to spawn my character inside a sphere collision, but it returns no overlap

on another project it does

what's missing ?

[hollow drift]

how do you spawn it?

What do you mean by: it returns no overlap

[upper linden]

it spawns at the start of the game

i mean it returns no result

but when my character spawns outside and i move in, there's a result

[hollow drift]

define "it"

collision box?

so your pawn spawns in a collision box and you want to read from your collision box overlap result that your pawn is one of the objects inside of it?

[upper linden]

BP actor with sphere collision component

[upper linden]

yes

[hollow drift]

ahh ok...

both are in the same bp?

[upper linden]

no

[hollow drift]

ok

send me screenshoot of your collision preset

[upper linden]

on both ?

[hollow drift]

yes

[upper linden]

my Character

Gravity BP

[hollow drift]

set pawn block

[upper linden]

where ?

[hollow drift]

block generates hit result -> there where you want to generate for your collision box a "hey i collided with you" event

the checkbox

[upper linden]

on my character you mean ?

[hollow drift]

your characeter is of the object type pawn

you want all pawns to be hit with your collision box

so your collision box needs to generate a hit event when colliding with pawn

this works only when you activate it

for example:

[upper linden]

there is a partial response

[hollow drift]

good, half way done then.

[upper linden]

print string works

but the interface isn't triggered

[hollow drift]

does the collision box has the interface?

what does this function do actually? never used it

[upper linden]

the interface is in the character BP

[hollow drift]

reminds me of zof...

[upper linden]

zof ?

[hollow drift]

nevermind. a unreal game which had issues with collision

back to topic

[upper linden]

interfaces are functions you call on another BP without casting to the said BP

[hollow drift]

oki

i could help you so far just because i had today the same issue but i have not touched interfaces yet

[upper linden]

thank you

[hollow drift]

no prob

[upper linden]

what bothers me is that it works ok if i enter sphere from outside of it

[hollow drift]

if you leave you need to add on end overlap

so game knows you are not inside of box anymore

[upper linden]

i did, it works fine

[hollow drift]

kk

if y ware inside

just add a delay of ,00001 or so

this does sometimes the trick

[upper linden]

delay on beginoverlap ?

[hollow drift]

delay before it spawns in for example your pawn should work too

i am not shure, but i had similliar issues before, whereby for example the game already calculates stuff despite it has not yet generated models

[upper linden]

it worked with delay, what the hell !!

[hollow drift]

this has been actually fixed and stated in a previous bugfix but well... as you can see... its not realy fixed...

orr...

something else i missed

[upper linden]

i have no idea

i wasted 3 hours for nothing

thanks for the help buddy

[hollow drift]

i read some post about it, cant remember which one but this was already a ongoing issue

[upper linden]

if you need help on interfaces let me know

[hollow drift]

would love to

shall/can i add you in discord?

[upper linden]

add me

[trim matrix]

Can anyone suggest an advance tutorial about cameras. I'm making a TPS game and need some complex camera systems. I want to separate the camera logic from the code base

[fading raptor]

Im having trouble figuring out how to destroy an emitter, but not keep it destroyed

I want to call the destroy component function when the branch is false, but when it is true, i want the emitter to spawn

My problem is it works fine once, but if i trigger this line of code again, i get an error that basically states my emitter is destroyed and i cant spawn it

How do I basically temporarily destroy an emitter

[hybrid ether]

Any idea what can cause this? 😄

[white plinth]

not sure but it ls kinda funny 🤣

maybe you should check the simulation physics?

[gritty elm]

can anyone explain how to setup xbox controllers mapping in unreal

for just moving third person character, mouse movement and jump

[white plinth]

https://www.youtube.com/watch?v=YA1r_gwS9yg

isn't this what you looking for?

not sure jumping is included

[gritty elm]

thanks, for unreal what kind of joystick should i buy?

like xbox controllers, or ps4 controllers

or basic joystick

[trim matrix]

Anybody experienced with PlayerCameraManager?

[spiral vessel]

I believe you are looking for the activate/deactivate functions. This will turn on/off the particle emitter without destroying the component itself

[white plinth]

enreal can set the action mapping both ps4 and xbox. so you have to buy up to platform i guess?

about this, i am not so sure but it says like that

[grizzled garden]

can someone please expain to me what is this matriela i just donwloaded?, coz it is souppsed to be a particle system. but this is a static matreal that does not change or animate or anything.

[grizzled garden]

help?

[dawn gazelle]

It's a material I believe you put into a particle system.

[grizzled garden]

how?

may u help me @dawn gazelle

it should be a particle system, but its not, if i create a new p system and put it in the required tab it wont show as it should be.

[maiden wadi]

@grizzled garden Nothing about that material is supposed to animate. It's just a mathematical function on pixel data that makes a neat pattern. In the end, the last node under ParticleColor may as well be a black and white mask texture. This is also either a #graphics question if it's about the material, or #visual-fx if you're using Cascade, or #niagara if you're using NIagara.

[grizzled garden]

then what do i do now? how to make it run in particle systems?

[grizzled garden]

Help

[dusk basin]

ik this seems like a basic question but for whatever reason my camera rotation for lookup and turn is not working on my custom player controller i did some testing and it works on the default player controllers but not my custom one

[faint pasture]

Is that mouse input in the controller or pawn?

[dusk basin]

its in the pawn @faint pasture

im trying to figure out if there is something else blocking or consuming inputs but for now i have no leads

fixed

[lean plover]

I'm trying to open level in a blueprint library, so where do I get context from?

[faint pasture]

@dusk basin What was consuming, the new controller?

[fallow creek]

Ig it is only for look around for that particular pawn 😅

I just started learning blueprint so if i say something wrong please don't mind me

[dawn gazelle]

you can just do get world context:

[lean pawn]

How does one restarts a blueprint?
I need the node so the character walks into a collision box and restart a specific blueprint

[green briar]

Anyone know why the particles wont spawn? The whole blueprint works, I just can't get the particle emitter to spawn the particles. I'm following this guide, too. https://www.youtube.com/watch?v=pq77asEjRaQ&list=PLL0cLF8gjBpqA8DcrhL_O9kD4jsUqhDR6&index=7

[dusk basin]

@faint pasture i knew something was off with me putting the rotation in the character so i put it in the controller and boom

[lean plover]

@dawn gazelle, Really appreciate your help, but I think because I'm calling from RemoteControlPreset it doesn't get set? My call just has no effect (I get a 200 OK response, but the funciton deos nothing).

[green briar]

IDK why but deleting the emitter node and reusing it fixed it

[lean plover]

Is there any point in using UE4's WebControl over something like VaRest?

[dawn gazelle]

As far as I'm aware there is no "restart" for a particular blueprint. Based on that, you have a couple of options:

1. Have a custom event that fires that resets all values in the blueprint back to their defaults, and have it link into where your Begin Play starts (if you want any of those events to fire)
2. Destroy your existing actor/component/whatever that blueprint is and respawn it and reattach as necessary.

[dawn gazelle]

I think the web control is for building a web-based interface into the engine, where using VaRest is just a means to communicate data in and out.

Not sure of the interchangeability, but I'd imagine at the very basis of them, they are just tools for getting data in and out.

The Web Control does require a server running to handle the commands, where REST can be done serverless.

[orchid garden]

am i going about this wrong for a widget? cast fails every time.

could of swore it was working before...

[lean plover]

@dawn gazelle You're right. I'd previously used a UDP listener running on UE4 alongside an external Rest provider, but I was hoping 4.26's WebControl API would be easirer. I need it in packaged runtime though, and experimental docs are frustrating.

[dawn gazelle]

Appears to work alright on my end when using a cast to "Character". What class does your MasterCharacter inherit from?

[orchid garden]

character class... thinking i have a a bp hickup again, i could of swore it was working and suddenly it started failing. it seems to be working on the other widget thats in the same panel so ... yeah... probably a bp hickup, just gotta figure out what...

[faint pasture]

@dusk basin Remember that all those nodes do is modify the ControlRotation. What that drives is up to you. There are options to use it in the camera, spring arm, character movement controller, and many other components.

[lean pawn]

Good Datura, I will go with the respawn option, thx

[orchid garden]

um.... could someone explain this error? lol

[dawn gazelle]

trying to access an out of bounds index in an array.

[faint pasture]

@orchid garden the last index in an array of length 23 is index 22

Starts at index 0

[orchid garden]

doh... so basically its telling me the array is only 22 slots?

[faint pasture]

It's 23 slots

[dawn gazelle]

No, you have 23 slots, but you're trying to access index 23 which doesn't exist.

[faint pasture]

Starting from slot 0

You should be doing a for each loop probably, that'll automagically hit them all

[orchid garden]

fixed ty 🙂

sorry for the no brainer question, my brain doesn't seem to want to work today lol.

[trim matrix]

Hey, how would i go about getting hh:mm:ss time based of sun angle?

I made a blueprint that changes time of the day by changing sun angle overtime but im not sure how i can convert that angle to a real time value i can use for other things

[dawn gazelle]

https://docs.unrealengine.com/en-US/BuildingWorlds/LightingAndShadows/SunPositioner/index.html

[faint pasture]

@trim matrix you should definitely drive it the other way. Given a time, set the sun angle

You also need lat/long/date

[orchid garden]

@dawn gazelle and if you don't want to use plugins?

[dawn gazelle]

You'd need to do a lot of math.

XD

[faint pasture]

If it's just for simple gameplay make an actor with a couple scene components to get the inclination right and drive it with solar time and latitude.

[trim matrix]

Alright, i will try that and if that doesn't help then i'll try to do what @faint pasture said, that's a smarter way of doing things

[faint pasture]

That's how I do it.

My outdoor lighting actor has a sky light, scene component pitched at 23.5 degrees with a directional light attached. I use site orientation to rotate the whole thing, then latitude to angle the first component, then time to angle the 2nd. Time also drives the sun and sky brightness and color.

[orchid garden]

couldn't you always just kinda cheat on the position using a timeline?

[faint pasture]

Ya that's how I drive it. But an input parameter is latitude which changes the sun yaw rotation plane. Also site orientation which yaws the whole thing to move North around.

[orchid garden]

this is what handles that ones yaw:

it was really just a attempt at making a day/night cycle on my part.

[trim matrix]

Hi I have 6 types of meshes, each a type of wasp nest. I'm designing a game where players can place these nests manually. I have a widget corresponding to each type of nests and when players click the widget, I want them to see several dozen 'ghost' locations for the corresponding mesh (or could show only those within a certain distance). When I click a different widget button I want all these old 'ghost' meshes to disappear and a new set of ghosts to appear corresponding to the new type of mesh. What would be a good way to do this that does not involve communicating to every single nest mesh in my game (may be up to 100)? Can I somehow tell the player character to only see meshes of a certain type (A, B, ... , F)?

[orchid garden]

if you make them separate actors couldn't you use a get all actors of type?

just a guess

[ornate cairn]

Is it possible to add an object that simulates physics but cant get pushed by the player or other physics items?

[orchid garden]

i know you can change the collision on the physics model to ignore the actor, but i don't know about other physics items.

[ornate cairn]

wait, so it is possible to have them collide but only affect the physics of one of them?

[faint pasture]

@trim matrix you got a couple things going on at once here.

@trim matrix you def. want a data table

[trim matrix]

I'd like to know how I can set mesh cull distance? if possible

[feral ice]

i want an actor to not affect the nav bound volume

how do i fix that

[faint pasture]

@trim matrix Why not just have an instanced static mesh component with instances at all the placement points within range.

[trim matrix]

sounds equally complicated

also I want to press say 'place unit A' but you can subsequently move around the level and decide a spot, but you only see possible placements that are close to you (so it's dynamic)

I guess I could just use LODs lol and have LOD1 be empty

[orchid garden]

can someone tell me why im getting this log error? The character doesn't even use the ThirdPersonIdle, so im at a loss...

[maiden wadi]

Hard to say without seeing everything. I'd go through any animation blueprints or whatever that are assigned to actors with skeletal meshes that use that skeleton. It may also be a ghost reference. I'd go through and compile and save your actors with skeletal meshes, and also do a Fix Up Redirectors on your whole content directory.

[orchid garden]

hrm ghost reference? been through the animation bp and nothing in there refrencing the thirdpersonidle, its just a very basic animation graph, idle/run + jump

their all pointing to the characters animations

[maiden wadi]

Hard to say. Are you playing any Montages, or PlayAnimation stuff from inside of any actors? The log is oddly vague. It implies that it was logged from inside of an actor class blueprint that is getting a reference to that animation somehow.

[orchid garden]

no montages, just that very basic animation graph

hrm... maybe something ghosting from the master blueprint to the child?

only reason i can think of, cause my master has the maniquin in it:

[maiden wadi]

And the child is overriding that skeleton with a different one and a different anim blueprint?

[orchid garden]

yep with a different skeleton, meshes, and animation

[maiden wadi]

Could be the reason. You could possibly test without breaking anything by just nulling out the parent's skeletal mesh. The child blueprint should still be fine. If the error goes away, that's probably where it was. Being just a warning though, It looks like something that's just auto corrected at cooking time, shouldn't pose a real issue.

At worst case, you could go to the ThirdPersonIdle asset, and check through the reference viewer to see what all it's connected to, that could connect to your assets.

[orchid garden]

hot diggity, yep its because the master had a anim. bp setup in it.

oddly it cleared two mesh loading warnings too.

just removing the animation bp from the master

[maiden wadi]

I suppose it likely checks that in the event that for some reason the child's skeleton is messed up, it might default back to the master. Which it would mess up on with the wrong AnimBP Override.

[orchid garden]

back to zero warnings/errors in the log 🙂 ty @maiden wadi

[orchid garden]

found the cast issue, i when adding the hud at 'event possessed' it caused the cast to fail, but when adding it to the 'event beginplay' the cast works normally.

[dawn gazelle]

Excellent

[dusk basin]

anyone know a good way to speed up falling when a player is lets say skydiving i already have a function for skydiving but i want the speed up to happen only when the user has pressed W or forward looking in a down direction

[orchid garden]

i thought event possessed came after the character had been added to the game?

@dusk basin when W is pressed check for falling, and actor facing direction, if both true, add X forward velocity?

[trim matrix]

Is it a generally preferred practice to embed another blueprint in a blueprint? Another solution I can think of is to add the same functionality as a component. Does anyone have information on what should I pay attention to?

[odd ember]

embed how?

[trim matrix]

with child actor component

[odd ember]

child actor components are generally no bueno

[trim matrix]

What is bueno?

[odd ember]

they're no good

most of the time

usually you would want to use components or blueprint communication instead

but I don't know your specific case so I can't tell

[trim matrix]

I'm not sure it can be a good practice, too. Probably I will use components

I will implement a rain system

[odd ember]

child actor components are never a good practice in general. it's symptomatic of attempting to hack around your code. you can spawn an actor instead and communicate with it like so instead

[orchid garden]

o.O

[odd ember]

yes?

[orchid garden]

"actor components are never a good practice in general."

[odd ember]

they aren't

[trim matrix]

I am not agree with you. Actor components are base of the ECS mechanism

[odd ember]

there is no true ECS in UE4

[orchid garden]

i disagree as well.

[odd ember]

you can disagree however much you want

[maiden wadi]

I think cranz meant Child Actor Components, not basic Actor Components.

[odd ember]

ah yes

sorry

my bad

[orchid garden]

ah

[trim matrix]

😄 sorry

[odd ember]

because we were talking about child actor components

not actor components

which are obviously the foundation of EC

[trim matrix]

Thanks

[odd ember]

(but no S)

[maiden wadi]

All a child actor component is, is simply an actor component that spawns an actor and keeps it attached to the actor that the component resides in. By the time you use one, you may as well just spawn an actor via another actor and attach it directly and keep a reference to it.

[odd ember]

plus for some reason the child actor component is a memory hog compared to just having another actor, and it has been known to cause issues

[trim matrix]

Thats good explanation

It can be useful at some specific cases

[odd ember]

I wish epic would deprecate it tbh

[maiden wadi]

In most use cases with a Child Actor Component, you can usually do the exact same thing with a new class of Primitive Component.

You could possibly use them for stuff like turrets on a vehicle. But like I said, by the time you do that, you may as well just spawn it manually and keep it's reference pointer in the vehicle. All the component does is add an extra layer to go through by having to get the child actor component's child actor reference and then cast to it. As opposed to just keeping an already casted reference where you're using it anyway.

[pine trellis]

is there anyway to move an inherited component to another part of the character? I need to move my interaction mesh to my widgetinteractionR

[orchid garden]

far as i know inherited components can not be reordered.

[trim matrix]

Is it possible to change the Game Mode in game ?

I mean, create a input for example and on this input, it changes the GameMode...

How do i fix the error: Infinite Loop detected?

[dawn gazelle]

Doesn't look like it would be in this bit of code.

[orchid garden]

don't see a loop in that event.

look at whats calling it

[trim matrix]

that's what the engine tells me...

wait

[orchid garden]

its telling you where it failed on the loop, you need to look at whats calling it, the loop is outside of that event

[trim matrix]

oh ok wait the problem happens when i use an event tick

[orchid garden]

o.O how are you using event tick? shouldn't fail on that either.

[trim matrix]

huhh im new to unreal engine, that should be something like a broken light that turns on and off

[orchid garden]

show us how you have it connected up to your event tick

[trim matrix]

no i am not using an event tick, that's all, i said that the problem happen even if i use an event tick, but that's all the code i have in the BP level editor

[orchid garden]

(im guessing the loop is inside show)

can't really tell you though.... cause i donno if 'show' is whats calling your light event, your light event itself doesn't have a loop in it.

[trim matrix]

ok there is something wrong with my project, it says that the error comes from a trigger box (i dont have any)

[orchid garden]

which means whatever is calling the "Light" event is what has the loop.

[trim matrix]

WTF the engine is detecting a console command as a infinite loop, the console command is R.Streaming.Poolsize 8000

guys there is a serious problem now, i deleted my whole BP and it still says that there is a loop detected (i saved them in another project)

[trim matrix]

How can I read data from data assets?

[dawn gazelle]

https://www.youtube.com/watch?v=gLWXZ3FXhO8

[pine trellis]

is there anyway I can add another chracter to the line by trace?

[dawn gazelle]

If you're trying to line trace from two places, you'd probably want to do a separate line trace.

[dusk basin]

@orchid garden i tried to do what you suggested but i dont notice a diffrence in velocity at all

would i add velocity or would i modify stuff like max walk speed or Jumpz Velocity etc

[maiden wadi]

@dusk basin What are you using for movement?

[dusk basin]

@maiden wadi character or pawn class with the movement component

my question is anyone know a good way to speed up falling when a player is lets say skydiving i already have a function for skydiving but i want the speed up to happen only when the user has pressed W or forward looking in a down direction

[maiden wadi]

Well, how you affect the velocity depends on the component you're using for movement. But mostly you'll probably want to turn something like ControlRotation into a facing vector and use that to add force or change movement towards that direction, also affected by gravity and current falling velocity.

[orchid garden]

@dusk basin sry wasn't paying attention to discord, i did it like this to launch my character forward on a doubletap:

[maiden wadi]

I've had a few thoughts about recreating the skydiving from Just Cause. Quite honestly, I'd probably use a projectile component on the character that I could enable and disable for flight.

[orchid garden]

just cause skydive... that would be pretty cool.

[pine trellis]

im trying to make an array and connect more then 1 button press but its not connecting does anyone know how to get it to connect???

or can I use an input action?

[dawn gazelle]

That node doesn't take an array of inputs.

[pine trellis]

can I use an input aciton?

I tried but it didnt work

[dawn gazelle]

Sure, but you can't input it into that node either.

[pine trellis]

so how can I do it?

I have keyboard and VR players

[dawn gazelle]

What event is firing that leads you to that branch?

[dusk basin]

@orchid garden still dosent seem like its pushing me at all when im falling

[maiden wadi]

I have C++ library functions for that. Takes a FName for the input to get the action mapping, gets all of the keys that action can trigger on, and loops over them to check if they're currently pressed, and returns true for the first one positive, returns false if the loop finishes.

[orchid garden]

if your using the values i gave it isn't much force to be honest, you may not want it overriding either.

[dusk basin]

i tried with my own values and with and without override and still nothing

[dawn gazelle]

What fires the AExternalControlPanel event?

[pine trellis]

I think im just going to use an OR boolean

and copy and paste whats before t he branch

[dawn gazelle]

I just hope it's not being fired on tick.

[odd ember]

sad part is your thinking is correct it's just that unreal doesn't have a way to register something for an input action as opposed to an input key

I made my own functions to overcome this

[maiden wadi]

@pine trellis Try something like this in a library. Or even put it in your player controller class.

[odd ember]

yep

I run mine out of the player controller class because it's a good place to route all your inputs through

[orchid garden]

@dusk basin you could try something like....

that should just keep adding speed... um .... forgot flight fwd mod was so i could set the +10 value to the air control boost multiper (it would be changed by other things)

there i cleaned it up for you:

that was a working fight thing based soley off character movement, not sure how you'd handle the replication though.

[dusk basin]

ill worry about replication ima try this and report back thank you

[low marsh]

@trim matrix Have you squared it away?

[trim matrix]

Yea, I restarted the engine and it’s working now... it was probably a bug

[low marsh]

Good to hear, good luck!

[trim matrix]

Thanks

[dusk basin]

@orchid garden its not passing through the first branch had to breakpoint

[low marsh]

@trim matrix I don't believe you can do it mid-game without reloading the level. I believe you can create shortcuts to your defaultgame.ini or defaultengine.ini and use openlevelname to quickly swap over, though.

I'm probably wrong with implementation, and I'm sure someone smarter than me will correct it, but I -think- you can also control shortcut swaps like this:

[low marsh]

You can do that in project settings > Collision, by setting up a custom channel, and then defining behaviors on the actor in the collision tab

[ornate cairn]

@low marsh do i create a channel for the player or the object?

[low marsh]

I'd think it better practice to do it on the object, rather than player, as it gives you more freedom to utilize the channel across different types of objects

[ornate cairn]

but whats the specific setting so that the player doesnt affect the object

i havent been able to find it

[low marsh]

When you select custom, you'll get this dropdown

I believe that should be self explanatory 😛

There are some fantastic tutorials that will go much more in depth, as well, on youtube. This should get you in the right direction, though

[ornate cairn]

i dont think i made it clear what my inention is. Basically, i have a system where you can pick up objects and move them around and drop them. Ive made it so that the object you grab disables collision with the player until the object is dropped and not overlapping the player. I also set it so that once you drop the object its linear velocity gets reset. Right now there are two things i am trying to do right now. One is to keep collision between the objects and the player but not have them affect the object, as in when the player crashes against the object, i dont want the object to move. I dont want the player to be able to go through the object. The second thing im trying to do is the same thing as the first except with the item being held, as in i dont want the item being held to be able to push or move the other objects in the scene which arent being held.

I spent a lot of time googling and still havent found out how to do it

[maiden wadi]

Are your objects simulating physics or something?

[low marsh]

Does this need to be replicated?

[ornate cairn]

yes

thats how i am currently checking whether i can pick them up

i want them to have physics, i just dont want them to be affected by the player

[low marsh]

Pretty sure a collision channel would do just that.

[maiden wadi]

Normally, it would, except that he doesn't want the player to be able to walk through them.

[ornate cairn]

exactly

[low marsh]

Block setting would stop that from happening as well, no?

[maiden wadi]

The issue is that players are kinematic. Which more or less means that they're a pill shaped 5000000 kajillion Kg object in terms of physics.

[ornate cairn]

but its already on block, so it wouldnt change anything

[low marsh]

I'd have it block, and tick can walk on to false, with a custom channel.

Pretty much Gandalf it

[maiden wadi]

That's just going to send the object flying when the player walks into it.

[ornate cairn]

yea

[low marsh]

If it's being "picked up?"

[ornate cairn]

were talking about the ones htat arent picked up

i feel like this should be something implemented into unreal, it seems like something that should be very simple, yet i havent been able to find how to do it

[low marsh]

I don't think I'm understanding your need

I'll let this alone, and hopefully someone can help ya figure it out

[ornate cairn]

understandable, i guess its hard to explain through text

[maiden wadi]

You might be able to get away with it by overriding event hit on the object and making it stop itself from moving.

[ornate cairn]

how do i do that?

so i should create a bp for the object?

[maiden wadi]

Possibly. You just need a way to override the Hit event for the object. I'm not sure if that'll work or not, I don't mess with Physics stuff much. It's usually pretty unreliable beyond cosmetics.

[low marsh]

This will open override hit

Just right click in your bp

Wherever you have your variables, etc

Will give you the it event node that you can customize

hit, not it

[ornate cairn]

right now there is no bp, so should i create a pickabbleObject bp?

[low marsh]

This should absolutely be a bp

[ornate cairn]

i plan to use this pickable objects for puzzles later on, but lets say there are multiple different type of objects in the puzzle, should i create different bps for each one and add this override on all of them?

[low marsh]

You can create a "master" bp that has the bulk of functionality, and create children of it that implement your special needs

[ornate cairn]

makes sense

[low marsh]

Right click your master, mine is called test, and select the tippity top option

[ornate cairn]

perfect

[low marsh]

Remember also that you'll be able to do things like overrides in the child, but you'll want to be careful and mindful, as, speaking from experience here.... It can get convoluted

[ornate cairn]

if i edit master after creating the children does it update the children?

[low marsh]

Yes

[ornate cairn]

perfect

[low marsh]

Your master, or parent, is the "brain," for the children.

[ornate cairn]

wym by making it stop itself from moving

[odd ember]

in general hierarchies and best practices exist to make it easier for you, not harder

[rough sinew]

Yes, but... sometimes if it is already placed in the world or attached to actors it could get weird

[low marsh]

A very common use of parent/child is with weapons (ie: firearms) where you build the basic functionality of the weapon, like projectile launching of a round, and create dynamic values with variables, such as amount of rounds that could be fired at a time, static meshes to use as display, etc. With them all being accessible in your child, you can swap things over and create "unique" weapons, just by changing a few values

[ornate cairn]

i see..

ive used parent classes in python before to make different types of pieces

same thing pretty much

[low marsh]

While not specifically applicable to what you're asking, I think it shows a decent idea of what sort of fun stuff parent/child heirarchy is capable of

This is a fundamental root of OOP 🙂

[ornate cairn]

i guess the next step now is to figure out what i need to override the hit event with

thank you for the help 🙂

[maiden wadi]

It may work to just zero out linear and angular velocity.

[low marsh]

While excessively simple...

If you want to ignore player, than true is where you tell it how to behave. If it's hit by anything else, it will say "Hey I was hit by an object that wasn't player" and from there you can apply whatever other logic you want

That would go onto the false

If you're making it as a parent, to implement children, you'll want a check state like this but with a lot more brain behind it, so you'll have more freedom in the children. You can determine from the false to loop through object types (ie: puzzle pieces, manipulatables, unpleasant inlaws) and create options that respond accordingly. Etc etc etc

The smarter the parent, the smarter the children

[rough sinew]

The only I would add is to avoid casting if at all possible. Dependency maps size can get out of hand quickly. Generally it is better to use blueprint interfaces.

[ornate cairn]

thank you so much @low marsh

you just saved me

this is what i put, but it still slightly moves when i hit it, it just stops immediately.

[low marsh]

@ornate cairn No worries, duder. Glad we could get it resolved somehow. I was super confused to the explanation at first of what you wanted, so I figured giving you a blank template to tag logic on would be at least somewhat helpful. lol

[upbeat copper]

does anyone know why my player turning speed is the same even if i change value of the turnspeed?

and also same on vertical axis.

It worked before on another project

I cannot figure out what is wrong with it.

[odd ember]

try increasing it to some astronomical number and see if it makes a difference

[upbeat copper]

It doesnt do anything.

even if i increase it to the maximum of Unreal Engine

For some reason setting default to the variable works but overriding it in instance defaults doesnt do anything

Do u know why?

[odd ember]

try using a different variable and see if you get the same results

[upbeat copper]

yes, i do get same result

engine restart also didnt do anything.

[odd ember]

could it be you're not using the right event potentially?

[upbeat copper]

How it could affect variable working when i set its default and instance default not working?

I dont think so.

[orchid garden]

my pins are connected differently but that really shouldn't be a difference... my base lookup and turn rate are 45

[upbeat copper]

My code also worked before in another project. that is really weird

[orchid garden]

4.26?

[upbeat copper]

yeah

[orchid garden]

try it in 4.25, might be a bug

[upbeat copper]

I dont have 4.25 installed so i would have to install it

I think i uninstalled it when 4.26 released

[orchid garden]

or some other earlier version, the add controller yaw/pitch hasn't really changed for a long time.

[odd ember]

yeah mine is similar to that, the naming strikes me as off

for @upbeat copper's

[maiden wadi]

You might also disconnect the multiplication and input manual values of different values to see if the spinning changes speeds. If it doesn't 4.26 might have some new clamp input speeds somewhere like the controller class.

[upbeat copper]

I'll try that

@maiden wadi The spinning changes speed. when i type 1 its different from 1000

It has something to do with the variables

[maiden wadi]

Does it print the correct value from them if you print them in the axis event?

[upbeat copper]

No. It print the default value and i have the value set to 360 in details panel defaults.

[odd ember]

have you ensured that your input axis isn't capped under project settings > input > axis mappings?

[orchid garden]

looks right other then you inverted look up, but you probably wanted that.

[upbeat copper]

yeah

i inverted it back in the blueprint

by multiplication

Might that be an engine bug?

[odd ember]

not unlikely at this point

[upbeat copper]

But then it was working on another project on same version of ue

I can reproduce it in clean blank project

easily

can someone other try to produce the same issue? then it would be clear if it is specific to me or not

really weird. if i print the variable in tick then it produres pattern from both default and instance override default.

[rain egret]

So I made a function for my procedural mesh that takes static mesh data and combines them all in one procedural mesh.
I now have a function called “make cube” that forms out of 3 premade static mesh. I am working on editable airships so I got parts like a basic cube a cube with slope etc. some of those parts overlap tho and you can see Z fighting on the normals.
What’s a good way to merge overlapping sections?

[upbeat copper]

like if my variable default is 40 and in instance its set to 0. then 40,0,40,0,40 you get it

It is really annoying but maybe i can work with it.

[maiden wadi]

Do you have two instances of it?

[odd ember]

try duplicating the class and see if it still happens?

last resort but maybe

[austere moon]

How do i make a destructible mesh only destroyed by projectiles instead of the player running into it too

[orchid garden]

so... im hearing people say do interface calls instead of casts... but in order to have the event fire on the item you want it to, you still need to do a cast to tell it where to send the interface call... or ... am i missing something?

i.e. if i want item A to fire off a interface call to Item B, im going to need a reference to item B to fire the interface call off on (target on the called interface call).

i'd really like to hear you guys explain how this is better.... honestly.... i don't see how.

[maiden wadi]

@orchid garden Interface events can be called on any form of pointer. So if you have Actor1 that is an Apple, and Actor2 that is a handgun, You could call the interface function on a reference of Apple that is either Apple, Actor, or even Object, without having to cast it to Apple to use that function.

[orchid garden]

again, explain how, Apple has a call to the interface "appleisfriend", Orange has a interface event setup, but its intterface event doesn't fire because Apple is sending the interace call to itself.

[dawn gazelle]

My custom game mode has an interface named "on Chat Channel Updated", I can also have subclasses of my game mode that also implement this interface. But, I can pass it like this, and it'll still end up getting to whatever the valid game mode is and implementing its interface.

[orchid garden]

here's a simple example of it not working....

it never prints the string.

[maiden wadi]

Use the message function in blueprints.

[orchid garden]

example?

[maiden wadi]

Honestly, I'm not exactly sure with the self reference, I normally just call the function directly if it's from the same class.

[orchid garden]

o.O isn't that kinda redundant if its in the same class? you could just call a event?

[maiden wadi]

If it's in the same class, it's pointless.

[dawn gazelle]

Use the (Message) one.

Interfaces are for cross-blueprint communication.

No point in using them within a blueprint.

[maiden wadi]

The reason that a lot of people use interfaces over casting is for two reasons. First is obvious, you need to do two different things in two different classes. Eat the apple, equip the gun, two different things with the same line trace maybe.

The other less known reason is encapsulation. You don't want your classes to chain load stuff. If your character has a weapon, that casts to a bullet, that casts to a particular boss, that casts to a specific spell, that casts to some AI, and those AI cast to other things... Well guess what all is getting loaded and used when you load a character?

[orchid garden]

i don't get one labled message:

[dawn gazelle]

Might need to unclick context sensitive

[maiden wadi]

Get a self reference, and drag off of that.

[orchid garden]

yep that showed it @dawn gazelle

[dawn gazelle]

Yeah dragging off stuff too seems to work for me a lot of the time XD

[maiden wadi]

It's because you need to cast the self reference to use the message function. It's the same as C++ and casting the pointer to the IInterfaceClass

[orchid garden]

still wants a target

[maiden wadi]

Self should be the target. It has to cast that reference.

[orchid garden]

doesn't fire the event with self refrence on anything but itself.

[maiden wadi]

What are you trying to call it on?

[orchid garden]

so again, i need a refrence to the object im trying to send it to...

widget to component

[upper linden]

which actor implents that interface ?

[maiden wadi]

Yeah, that's a pretty brutal one. Only way I know of is to pass a reference into the widget from the component.

[orchid garden]

so interface calls aren't as grand as they are made out to be then.

this was all in a attempt to avoid a cast, but nope.

[upper linden]

but you call an interface from another actor

not on the actor itself

[opal nimbus]

Not sure if this is the right place to ask but how can I copy this floor and connect them to eachother like so? I could've sworn there used to be a hotkey like Alt before but that isn't the case

[upper linden]

why are you calling it from its own actor BP ? you can just use a custom event

[orchid garden]

Explain to me how i fire a event on a actor component from a widget then @upper linden

[upper linden]

did you bind the widget variable to a function ?

[orchid garden]

eh?

[upper linden]

eh !! you don't know how to bind a widget to a function ?

what's the variable you trying to update in your widget ?

[orchid garden]

a widget inside a widget.

not a variable

[upper linden]

i can't help you if i don't see it

sorry

[upper linden]

i'll find you a good tutorial tho

https://www.youtube.com/watch?v=yxqSkFNAzE0&list=PL4G2bSPE_8uktjEdP4ZuRq5r2o4JMdZfM

best inventory tutorial i've seen

[orchid garden]

all i need to do is send a command to the actor component so that the widget updates. and i was trying to avoid casting to the character to get a reference to inventory component.

[upper linden]

hope this will help

[orchid garden]

no that one wont.

its a totally different inventory system

[upper linden]

by updating, what do you mean exactly ?

increase/decrease stack? change thumbnail ?

[orchid garden]

update the information for the item in the slot.

[upper linden]

ah ok, the tooltip

isn't description a text variable ?

[orchid garden]

the tool tip is part of it yes....

[upper linden]

so you have the title on top

[orchid garden]

all the slots are stored in the actor component as a array, the actor component when info is sent, updates the item in the array and sends the update to the widget.

[zealous moth]

@opal nimbus you are looking for "vertex snapping"; move the model and while in movement, hold the V key. The blue vertices will appear and you can snap them. Alternatively, if you need to snap a lot, look into spline meshing and more precisely HISM. Check this video: https://www.youtube.com/watch?v=ulb4escy8Yw&ab_channel=PendingKill

[upper linden]

the picture, the descriptio, weight spoil time and Right click text

looks like a struct to me

[orchid garden]

the information is stored in the widget component as a struct yes.

[dawn gazelle]

What I did for that, is create an event dispatcher in my inventory component "Inventory updated", and then have the event bound in every slot, which then looks at a reference to the inventory that was fed to it when it was created to see what the inventory has.

[upper linden]

you need to bind it to a function that updates the different infos

[zealous moth]

@orchid garden you should use master classes to store your struct info instead. Otherwise you will have to refer to it everytime and cast into it appropriately. You may refer to an older widget. This video goes over master classes and passing info: https://youtu.be/hOUdrom37-Q

[orchid garden]

@zealous moth the widget with the information struct is store in the actor component which is part of the master class.

[zealous moth]

ah it didn't sound like that based on what i read

[orchid garden]

@dawn gazelle that sounds like what i need.

[opal nimbus]

@zealous moth I mean the actual copy hotkey. Holding V just grid snaps my current actor (the floor)

[zealous moth]

oh you want to copy it? hold alt and then move it @opal nimbus

[orchid garden]

its the array thats stored in the actor component

[zealous moth]

alright, i am confused, what is the "actor component"? Your character?

[orchid garden]

its just that, a actor component, its added to the player character to store information, functions etc..

[zealous moth]

oooh i see

ok

i forgot we have those for a moment ^^"

[zealous moth]

yup

that

i know, my bad

[orchid garden]

🙂

[opal nimbus]

Lol oh my god

Now they're misaligned

[opal nimbus]

I JUST WANT TO COPY THE FLOOR LOL WOW

[zealous moth]

use spline meshing or grids

[upper linden]

bind button to the right @orchid garden

[opal nimbus]

I'm literally using the built in grid, what even

[orchid garden]

yeah i know how to bind parts of a widget to a function

[upper linden]

what's the problem then

[orchid garden]

but still your in the same boat, the function is in the widget.

[maiden wadi]

Please don't use UMG bindings. If you're going that far, just use tick.

[orchid garden]

gah ticks

[maiden wadi]

That's all bindings are. Except each one of them is individually called with extra overhead.

[orchid garden]

were getting off track of what i was trying to avoid though.

[maiden wadi]

In short, if that widget always casts to the same component, just cast to it. You're not going to save anything using an interface.

The only reason to interface that, would be to have the widget get the same style information from different classes.

[upper linden]

it's fine if you just show it for a few seconds

[opal nimbus]

Lmfao this is pretty trash ngl

Literally refuse to align with the built-in grid 😆 🤷

[maiden wadi]

I play Oxygen Not Included. You should see how complicated that game is. It's insane. Yet it runs beautifully. Right up until you open UI. Then it shits itself by half your framerate. UI optimization is serious. Bindings are the worst thing ever.

[zealous moth]

That may be because the size doesn't correspond to the grid

[orchid garden]

even when in top view?

if your copying more then 1 at a time, yeah they mess up the alignment to snap all pieces individually to the grid unless they are childed to the first piece.

[opal nimbus]

@orchid garden Happens on the first snap, I'm trying to snap these together to start making the flooring and it started happening immediately

Idk, either I am not doing this correctly or this is not very intuitive at all

[zealous moth]

look at my video instead of wasting time

[orchid garden]

i'll line up a set in a single row, move all of the others to be a child of the first one, then selct the last to the first child, and then duplicate, and drag the first one to the next position. your grid snap can mess you up too depending on the size of the mesh pieces.

[opal nimbus]

Nah I hard pass on all video tuts these days, hence coming to the Discord to seek support on the issue to begin with, as it was introduced whilst following a video tut 😆

[orchid garden]

alot of store bought pieces don't stick to uniform scale for the parts, i've had ones 198x204, instead of 200x200 or 195 x 205

[opal nimbus]

If you've some kind of explanation that is more respectful of my time I'd prefer that though for sure

[zealous moth]

nah, feel free to engage in newbie mistakes

[opal nimbus]

I'm just confused considering the guy in the video tut does the snapping perfectly fine and doesn't seem to suffer from this misalignment in the way that I do, despite us using the same content

[zealous moth]

it's a stepping stone

[opal nimbus]

I mean again you can explain it to me if you are aware of a solution or you can pop off with some pompous engagement tactic like that 🤷 you look like an ass in the latter case tho I suppose that's your prerogative

Has anyone successfully migrated a board engineers tank track system to their project? https://forums.unrealengine.com/community/work-in-progress/54936-assets-open-source-tanks-tracks-and-n-wheeled-vehicles

[thin cedar]

So I've managed to make my game crash consistently when trying to pickup an item

but I don't know how I did that

Can anyone here tell me what I need to fix with crash reports?

[odd ember]

rather tell us if you have some loops somewhere or if you're doing something on tick

[thin cedar]

No loops but I can check my event ticks

[odd ember]

if you crash on game start you're likely being forced out in some infinite loop somewhere

ticks, actors calling each other or themselves recursively

[thin cedar]

Nah its not on start

thankfully

[odd ember]

what you can actually do

is

go to your item pickup

and use a breakpoint on the event

that shouldn't crash

then follow the trail until it crashes

[neat frost]

@odd ember That's a cpp feature

I don't think u can use breakpoints in bp

[thin cedar]

I fixed it

somehow

Thanks for the help

[odd ember]

you most definitely can

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Debugging/index.html#breakpoints

[zealous moth]

@neat frost right click node, select "add breakpoint"

I just learned some 😉

[dusk basin]

Anyone know how I can speed up the falling speed of a character kind of like how in fortnite you fall drastically faster when holding down W looking down

I’ve tried modifying gravity scale world gravity etc and it does not feel like I’m going any faster at great heights

I’ve also tried adding input vectors on the Z scale and no effect

[desert flame]

Im trying to spawn random city blocks but even though im getting the print string working, and the level name working, it doesnt actually spawn the level in the world. Any solutions?

[last stump]

Not sure if this is the best place but is there a way to tell if the sub levels are all loaded with world composition?

Like i'm doing world composition right now and sometimes when i load in (from loading screen) after the loading screen it's still loading some textures, objects, etc.

This would only be for initial appearance within the world not while on-going but just when you initially enter the world i want it to take off the loading screen once it's all finished?

[hardy swallow]

@last stump What you're talking about is texture pop-in, and while this really isn't a complete answer to you question, it should help with the pop in https://answers.unrealengine.com/questions/343646/texture-streaming-pool-over.html

[last stump]

@hardy swallow is there something about all actors / static meshes?

Like i wouldn't be so worried about textures but there are sometimes like terrain isn't all loaded, objects, etc.

I'd rather just wait until the world composition isn't trying to load what it needs to load and it look all meh when the player logs in and have them wait a few seconds for things to even look right

[hardy swallow]

It's only about textures, not sure about the other stuff

[neon sorrel]

Does anyone know the best way I can make a door "explode". Its a static mesh and trying to figure out how I can get it to simulate physics and fly off its hinges when interacted with

Is there any easy way to enable physics at runtime on a static mesh?

[fallow creek]

Hello everyone I am new here just started to learn blueprint with minimumal knowledge of programming

[stray island]

Its easy work around but also I think there’s a free destructible plugin in the market maybe u wanna look it up

[neon sorrel]

Sorry for not updating things, I found out a way actually

I just added a impulse to the static mesh and set simulate physics right before with a 0.2 second delay in between

Yeah thanks seanny it was just being a bit wonky at first

[round dock]

is there a way to get a camera view from a scene capture component 2d?
this node here only takes an actual camera, and I can't find anything equivalent for a scene capture
or, just any way to get the view projection matrix of a scene capture

[brittle fiber]

this one is easy

[upbeat copper]

I have same issue that i had previously. This is the setup and it prints 40 even if i change the value of speed in instance details panel.

And it also happens on new blueprints and on new projects too.

And on all variable types for some reason

[grizzled garden]

guys help me why the heat effect is diffrernt when i play

[upbeat copper]

I think it is something on my side because it worked before and other people isnt having same issue. Or if i somehow broke my unreal engine 😄

[grizzled garden]

@upbeat copper can u help me

[upbeat copper]

I can look. i am not sure if i am able to help

[grizzled garden]

ok

[upbeat copper]

Do u mean that in editor it doesnt looks like this?

[grizzled garden]

the heat faze get weaker

when i play

[upbeat copper]

What those errors / and warnings are?

[grizzled garden]

nothing

ignore them

[upbeat copper]

okay.

[grizzled garden]

they are not related to the issue by anyhow

i still icant find what causing the heat

to be weaker

in the gameplay

[upbeat copper]

Are you using post process or what to create the heat?

[grizzled garden]

a simple matrieal

[upbeat copper]

I am not sure what would be causing it.

[grizzled garden]

me neither

[weak kindle]

how can l set my projectile followin only direction of camera and not rotation

?

[upbeat copper]

@weak kindle Do u mean like so it shoots projectile in the direction of the camera?

[weak kindle]

w8 l will send screenshot

[upbeat copper]

Okay.

[weak kindle]

l dont want follow that movement

[topaz iron]

Would like create event on projectiles overlapping/collision. Can't get it working. Any advice?

[upbeat copper]

@weak kindle So u mean that the projectile would follow the direction of the camera but not position?

[weak kindle]

yeah onnly left and right

[upbeat copper]

so not up and down?

rotation

[weak kindle]

yeah

[upbeat copper]

Have you tried to change the projectile object (blueprint?) Position to world instead of relative? If it is child of something

The little arrow left

[weak kindle]

l have only add a spin rotation

it fix

now its ok

[upbeat copper]

What u did?

[weak kindle]

get it off firstperson camera and set on blueprint setrelativerotation=0

so that will moved as capsule

[upbeat copper]

Okay. 🙂

[weak kindle]

how do i destroy a projectile properly after it has been spawned? this is my weapons and projectile BP
https://i.imgur.com/fQ1YBuD.png

https://i.imgur.com/iYq0NA2.png

[weak kindle]

l used event hit on my projectile

it works so good

[tall pine]

i need the projectile to despawn after a certain time as it's not hit based for me

[weak kindle]

causel can use and interfaces

then on ur input add call function

to call a custom event

and target ur projectile

[viral torrent]

@tall pine just put a timer in your BeginPlay Event

if the projectile timeout call destroy

beginplay event of your projectile actor

[tall pine]

beginplay works

[upbeat copper]

I resolved my issue 😄

[viral torrent]

also there is a property to destroy an actor after a certain time

[tall pine]

what is that property called?

[viral torrent]

@tall pine Initial Life Span

[tall pine]

thats better

[viral torrent]

and you can put your vfx (like explosion) if needed inside EndPlay

[tall pine]

oki

thx

[upbeat copper]

Anyone can help? Why i have two player objects when i play the game? I only have one in world outliner but as soon as i start the game then other player appears.

[dawn gazelle]

When the game starts your player is probably being spawned in - you shouldn't have to place one in the world.

[upbeat copper]

oh. Thanks 🙂

That was the issue.

that might also be the issue for that when i edited player instance variables they didnt do anything. If it spawned another player.

Thanks for the help 🙂

[formal echo]

I want to replicate movement speed as a custom event on the server, but I kind of need it to have an input. Now... I heard having inputs on those kinds of things is not a wise choice, is that true?

[viral torrent]

you use the Character Movement Component (CMC) ?

[formal echo]

Yep

Should I make my own system to do so?
