[tawdry surge]

#graphics is a better channel for this, but you need to change the tiling in the material or material instance

[wraith eagle]

if it was like a ""plane" you cant change tiling size?

[tawdry surge]

The shape of the mesh doesn't matter for this

[short pawn]

Add a texture coordinate into the uv of your texture and mess around with the u and v values untill it's the right ratio

I mean in the material blueprint

Does anyone know of a way to rename assets from the explorer without breaking them?

i want to rename this assets, but by doing so, i broke the reference to the editor and i can't import them later

[jade sedge]

Can someone help?

[mental trellis]

You really can't rename assets in explorer.

Anyone know how to save a grid inventory, I have create one and now I like to save or load. But I don't know how to get the items and position of evert grid because isn't like a normal inventor. I had create the inventory sistem of that channel https://youtu.be/4CjpBoKl6s8

Hi. You can write your own script in python or blueprints

[hexed ivy]

Anyone know why I can't move any actor in the viewport ?

using the arrows

[maiden wadi]

Most likely has a construction script setting it's location.

[hexed ivy]

happens for every single actor

and stuff I place in the world spawns directly on my camera, not on the ground

[maiden wadi]

That odd. Can't say I've personally experienced that. O.o

[polar narwhal]

[trim matrix]

Hi everyone! i need to spawn tiny bricks inside a sphere..
in houdini i would make the sphere a volume, and then use a pointFromVolume, and then packAndCopy bricks to the points..
Do you know how to do such a thing in unreal?

[prime berry]

DOES ANYONE KNOW A BETTER WAY TO DO THIS

I HAVE BLASTED MY HEAD OFF TRYING

[obtuse herald]

random unit vector * sphere radius + origin location

[polar narwhal]

I have a silly beginner question, I have a trigger area and I want it's blueprint to access a boolean inside these cylinders

when the cylinders enter the area

is this possible?

[obtuse herald]

yes, have a look at overlap events

[polar narwhal]

there's like nothing I can find online

[trim matrix]

wow! trying right now! thanks !

[polar narwhal]

I have that, I just don't know how to get the overlapping object's boolean

[obtuse herald]

ahhh

alright

[prime berry]

guys please tell me if anyone can help me out, not to sound impatient but my head is hurting, its so complex that i cant even explain the problem

[obtuse herald]

take the 'Out Actor' from begin overlap, cast it to your cylinder class and voila you can access the variables

[obtuse herald]

without no problem there is no solution

[prime berry]

the thing is, through this the meshes are changing but its stuttering during the change and thats annoying me, im trying to make a smooth animation using like 4 meshes, i just want them to interchange between each other and create a blocky animation kinda thing

im recreating mario, so ive made a voxel mario and im trying to make it walk. To make it walk ive made two meshes of 2 poses of walking and i want them to keep playing back and fourth when mario walks but its just not happening cause setting the visibility using tick is the only way i could find and its still not working. Is there a better way? Im new to this

Its very jittery and glitchy. And i dont know how im supposed to make animations using just 2 meshes

[polar narwhal]

um

like this?

[obtuse herald]

yes

[polar narwhal]

and what now?

[obtuse herald]

you can access the boolean via that pin

that is your reference of your controlled object

[polar narwhal]

hmmmm

it's not letting me do anything lol

Oh nvm

got it

bruh

[obtuse herald]

1. You could always change the mesh instead of changing the visibility for four meshes. 2. You could use a timeline instead for the animation.

[prime berry]

how am i supposed to change the mesh, does it not allow you to only change the skeletal mesh?

this isnt a skeletal mesh just to be clear

and how do i use a timeline to switch between meshes?

[obtuse herald]

something like this for example

[trim matrix]

it's working but i can't get "simulate physics" to be ON in the "Add instance static mesh"

any idea?

[prime berry]

THANKS SO MUCH LET ME TRY THIS OUT RIGHT NOW

and does the timeline track have to be even track, float track or vector track??

[obtuse herald]

instanced static mesh don't support physics

[obtuse herald]

in this case I used float track

[prime berry]

okay lemme try it out

thanks so so much

[trim matrix]

damn ok; good to know

[obtuse herald]

maybe particles are more what you want

[trim matrix]

but can i apply physics to particles?

and have alambic to be spawn from them?

[obtuse herald]

pretty sure yes

but I never really worked with particles (especially not with niagara) so I can't help you there

[prime berry]

so im using this now

and nothing is happening apparently

is there something wrong

[obtuse herald]

yeah 1. you need to connect 'BeginPlay' with 'Play' 2. you didn't set a static mesh anywhere

[mental trellis]

You havne't connected anything to the static mesh pins? Or selected an asset?

[prime berry]

OH HAHAHAHAH im so dumb okay

[obtuse herald]

and you also only want to play the walk animation if you're actually walking, that would be another branch

a wait nvm

you changed jumping to walking so you're good there

[prime berry]

wait

a question

[runic parrot]

yeah, i'm building that one but running into some problems to get the right index

[prime berry]

its asking me to connect something to target

should i connect the original staying still one

[obtuse herald]

yeah set your player mesh component as target

[prime berry]

okay

[obtuse herald]

and then set the static mesh to one you want there

[prime berry]

OMG

IT WORKS

[pale flare]

anyone know how to get the location of where the playera camera is looking

[prime berry]

THANK YOU SO SO SO SO SO SOS OSNAISHGPIOASEHRGIOU SO MUCH

this is so cool

i love this so much

[obtuse herald]

you're welcome

[prime berry]

if i have to enable jumping i just use the same thing right

[obtuse herald]

yeah

basically another branch before walking

[obtuse herald]

use a 'LineTrace'

[prime berry]

and then if thats false then i just continue the original code but if its true i set the mesh to jumping

[obtuse herald]

exactly

[prime berry]

thats so cool dude is it okay if i send you a friend request?

youve helped me out a lot man and that means a lot

[pale flare]

what line trace is it

[obtuse herald]

start would be: camera location; end would be: camera forward vector * 10000 + camera location

[obtuse herald]

[trim matrix]

Hey guys, how can i edit a BP's variable in a different BP?

[pale flare]

yes

so you can use "cast to (blueprint)"

im not the best to explain it so hol up

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/CastNodes/

[trim matrix]

awesome!! checking it out ! thank you!

[pale flare]

if you have any questions let me know ill help the best i can

[trim matrix]

ok so what i uderstood is i need to add a CastToBlueprint2.. all good, the issue is i can't plug the variable to share/edit in it

[pale flare]

can you show me what you have so far

[trim matrix]

i'm not sure what to put in object?

i need to put Pod Switch variable in object

but i can't

[pale flare]

so to change the variable you must drag off "as new blueprint1" and type set (your variable)

in theory it should show up, as far as object, that just depends what type of blueprint it is

[trim matrix]

yes!

[pale flare]

did you get it to work?

[trim matrix]

oh but wait. CastTo… has to be added in the BP2 that will control the variable of BP1 right?

right now it's in BP1 which has the variable i want to cast

[pale flare]

yes it should be switched

[trim matrix]

awesome!

the only part i don't get is "GET PLAYER CHARACTER"

how do you get that node

[pale flare]

are you casting to your character?

[trim matrix]

it's not a character.. just a switch

[pale flare]

hmmm im not sure what to use as the object reference

give me one second

[trim matrix]

thank you!

[maiden wadi]

You need a reference to the object to cast. GetActorOfClass, LineTrace, StoreReferneceSomewhereGlobal, Interfaces, etc. all get references but cast them as Actor class which is what you would have to cast to your BP

[pale flare]

get actor of class would probably work best right?

[maiden wadi]

Well. Interfaces don't. They're more or less lazy casting. But point is you need a pointer to the other object first.

Usually you get these based on the relationship between the two objects.

[pale flare]

i have to go but can you take over, im just a novice anyway :)\

[trim matrix]

it gives me an error when i GetActorOfClass a staticObject

[maiden wadi]

What is the relationship between these two objects?

Why does one need to reference the other?

[neon estuary]

How to drow a dative base on mouse position I got this graph and have no idea where to go next

[trim matrix]

well i have a loop that says; increment, and once you increment, i connect the loop number to the other blueprint. so each time it increment

[trim matrix]

in the other blueprint

or maybe should i try to merge the 2 blueprints?

ah well one of them is a UserWidget BP...

and the other one is an actor BP

hmmm

not sure i can merge that

[maiden wadi]

Do you plan to have more than one of the actor class in the level at any one time?

Also is the Widget added to viewport, or is it in a WidgetComponent on the actor?

[trim matrix]

yeah

i want the BP 1 to be the main conductor.. so i'll have 2 other BP changing stuff too, driven by that main BP

[trim matrix]

widget component

[maiden wadi]

In your actor's Beginplay, you want to get that component's pointer. Drag off of it, GetUserWidgetObject, Cast that to your widget class. Make a function in the widget that takes in the actor's class. And call that function from the beginplay of the actor and pass self through.

[trim matrix]

ok! trying that

[maiden wadi]

Actor.

Widget

Basically you're telling the widget what the actor is. Now that widget can use MyActorPointer to access anything it needs from that actor.

[trim matrix]

fantastic! doing that!

🤞

hay so im working on a multiplayer fps game and im using UE4's shootergame template as the base and im testing out the multiplayer and I can figure out how to start it does anyone know

Hi I have this parabolic jump right here a vector. I want to control the end point location from a parameter. Im new to timelines, how can I make that vector a parameter?

[maiden wadi]

Ah. Not sure, haven't tested Shootergame in multiplayer. Chances are you just need to package it.

[waxen knot]

IDK I should just be able to start a lobby in the editor

[maiden wadi]

Probably. But sessions won't work in the editor.

[waxen knot]

there should still be a button

[maiden wadi]

It's probably a map if it exists.

[waxen knot]

ya im in it

thats what I mean

and I cant find the widget its in eather

[maiden wadi]

Not sure you can edit timelines like that. Most times people go for stuff like a 1 length float or vector and just multiply it to their dynamic needs.

[mossy mist]

ah ok ty

Hi everybody! is there any way to change the sorting used for the items show on the editor?

(content assets)

[coral lance]

Right now i have the blueprints set up for when pressed the gun would be equipped and on release of the button it wont be is there a way to have it toggle instead of on release?

[dawn gazelle]

Use a boolean variable called "GunEquipped". On your button press, check if the value is true. If true, do whatever to unequip, then set the boolean false. If false, set the boolean true, then do whatever you do to equip your weapon.

[coral lance]

thank you i will test this out and update

Hi! this sprites are created from one big texture, is there any way to assign a new texture reference to each one?

[neon estuary]

Ok ill try again I need to setup the mouse cursor in 2d map I got this graph and It won't show my sprite on the map

[maiden wadi]

Viewport Position != world position. You need to get the local controller and project the mouse location from screen to world, then probably do a LinePlaneIntersaction(Origin&Normal) with the plane being your 2D world's side direction.

[neon estuary]

ok thx'll try it.

[coral lance]

i tried some version of what you said but it didn't work is there anyway you could provide an example i can work off of

[coral lance]

OMG THANK YOU i will implement this rn and update

[coral lance]

question what is the last node. sorry im REALLY new to this. this is my most ambitious project

[dawn gazelle]

I just put those in as place holders.

Whatever you do at that point is whatever code you have currently to equip or unequip your weapon.

[wicked osprey]

Hello guys. What is the best place to create a pause widget? Character or controller or another?

[glossy drum]

Has anyone used Movie Render Queue from blueprints?

I am getting an error "Cut State: uninitialized"

[minor wolf]

so im trying to Get MySubsystem in a UObject blueprint but its saying its unsafe and that the Context Object pin needs a connection but there is no context object pin?

[dawn gazelle]

Best place to create the actual widget is in the HUD class, but the pause system should be controlled by the player controller.
Eg: You have an event dispatcher in your player controller that can signal when the game is paused. Anything that specifically needs to know when the game is paused (like the HUD) would bind to it on begin play. When you press the pause button on the player controller you can call the event dispatcher. The bound event on the HUD should then create and display the widget. On leaving the pause menu, the HUD can remove the widget.

[torpid hound]

Context object is a hidden pin, generally used to help the underlying cpp find the World. What is the type of the blueprint parent and what kind of Subsystem is it?

[minor wolf]

blueprint type is UObject (its actually Outfit which is a UObject but doesnt override any functions), subsystem is a WorldSubsystem

[torpid hound]

I don't know for sure but you might not be able to get a Subsystem from that context. Your blueprint won't necessarily have a world to reference, which is why is saying it's unsafe

[minor wolf]

hm. it seems that UObject::GetWorld just does an outer call to GetWorld. in this case i think its the gamemode that creates it? either way. maybe ill switch to AInfo. UObject is giving me quite a few issues

[torpid hound]

Yeah, an actor or an actor component will definitely make your life easier

[wicked osprey]

Thank you🙏
And if i want create widgets with health, ammo count, and another I must create them in Widget, which i created in HUD?

[earnest tangle]

Well found a very nice gotcha 🤔

You would think this worked... but guess what... nah. It does the same thing as if you used a foreach loop to do this :P

[dawn gazelle]

It's not a matter of must - you can create a widget anywhere.
It's just usually best to create in the HUD class - this can help you keep your widgets separate from your game logic, so if there's any major changes to how you want your HUD to behave, or to how you want your other classes (like player controller) to behave, you're not necessarily going to have to completely rebuild the functionality of both.

[wicked osprey]

Thank you😁

[pale iris]

When I drag and drop a character into the level the movement works fine but if I spawn an actor into the level it does not move. Under Auto Possess AI I have Placed in World or Spawned so I dont know what the issue could be

[dawn gazelle]

Do you have an AI controller class defined in the class you're spawning?

[proper depot]

does anyone know why a Get Socket Transform in world space would be returning a transform in the parent bone space instead? The target is a skeletal mesh attached to a bone on my character's mesh. I put together a simple reproducer outside of my project and Get Socket Transform in world space does work as expected, so I think it's something I've toggled off or missed in C++ code.

[vast urchin]

Hi, im trying to implement a BunnyHopping type of movement into my game and i have a start by following this guide http://adrianb.io/2015/02/14/bunnyhop.html. But i am very new to ue and have hit a roadblock and have no clue how to debug my error
Its written very poorly but this is my 1st attempt at something like this. At the moment it just moves my character up when i press w, down when i press s, and moves me left and right but at astronomical speeds, the speed also never disappears. Literally any help would be appreciated. dm me if needed or @ me

[pale iris]

Yes I have an AI controlled class that is running a behavior tree

and the AI is spawning as well when the actor spawns

also sorry Im a noob lol

[dawn gazelle]

Do you have a valid nav mesh where that actor is being spawned?

[pale iris]

yes it looks like it could it be a collision issue like maybe it's stuck in the ground or something?

[zealous fog]

Have you used the AI debug screen?

While playing press the apostrophe key

Look at your spawned character

Press 4 to activate the pathfinding view

On your numpad

Probably also works on the regular 4 but I always use the numpad so not sure

You can then see if it has the right controller, is using the move to task, and what it's currently trying to do pathfinding wise

(Look at your ai then press apostrophe)

[pale iris]

That is a very useful tool thank you! I found something interesting. When I drag and drop an actor onto the level the movement works fine and it says that the movement mode is walking like you can see below.

But when I spawn the actor the movement mode is set to falling instead like you can see below.

[hardy fable]

In order to make UObject derived classes be able to use all blueprint nodes that require a world, you need to override GetWorld in c++. since you have a subsystem i assume you are using some c++. Uobjects have some magic that allows them to know if that function has been overridden, and once it is those errors go away. the fun part then becomes providing your get world function with something valid. depending on what your doing it isn't that hard. if your UOutfit contains a pointer to any other object, you can just defer the call to it instead.

virtual UWorld* GetWorld() const override
{
  if (!IsValid(SomeOtherPointer)) return nullptr;
  return SomeOtherPointer->GetWorld();
}

returning nullptr probably isnt the safest, but it its worked for one of my classes so far at least.

i needed to do some async loading in a uobject class and ran into your same problem

[main pollen]

I made "get hit result under cursor for objects" node sensitive to a custom object type but it still gets results from other object types. How can I prevent this?

[pale iris]

@dawn gazelle @zealous fog Thank you so so much I just got it to work! You all are lifesavers 🙂

[frank salmon]

hello, does anybody know how I can use the ease nodes with tick function?

seems like there is always a snap when using them without timeline

[main pollen]

So it seems that it gets the result correctly but the problem is that even if there is an another actor with a different object type getting in the way of the cursor, it ignores that object and gets the result from the actor that has the custom object type anyway.

trying to make a wide range spell but it only damages one actor at a time

anyway to make it damage any actor in its collision

without the delay it works perfectly

but does way more than 100 damage

[trim matrix]

is there any way to spawn the subtitles according to the time i set in blueprint

[dawn gazelle]

Ok, there's nothing sticking out in your GetClosestPlayer function. I'd recommend trying to break down your ResetAI event into smaller pieces so you can see where it may be going wrong. Like, what happens if you use only the first AIMoveTo and on Success add a call to Reset AI - basically disconnect everything before this branch and then just call Reset AI again.

[small halo]

Okay let me try that now

[coral lance]

i am having a weird bug. Would someone be able to help?

ill make a video so you dont have to download anything

[dawn gazelle]

You can do a GetOverlappingActors call, set the target to the specific component (R1) then loop through the actor list to apply the damage to all the actors. If you want the total damage split between all actors, then you'd want to divide whatever the total damage is by the Length of the Overlapping Actors array then you'll get the damage per actor which you can then plug into the apply damage node.

[coral lance]

https://youtu.be/tH3Fo_4MlFU

[small halo]

it works when i disconnect and add reset ai after

so no issue is there

[pale flare]

it still does over the damage i set, i think its repeating

[dawn gazelle]

Ok, so what does your Combat? function do

[small halo]

https://gyazo.com/663c93c85b0a87c61a27779ed7a91f64

[coral lance]

would someone be able to help me I am very confused

[dawn gazelle]

I'm starting to think the logic here is all ok. Is there any where else that you're using code that is moving this AI?

Perhaps, something that is working with your strafe enumerator?

[small halo]

https://gyazo.com/97da4527f1b7ded9e64101628a446d09

thats the strafe function

the ai works perfect when im next to it but when i go away sometimes he still maintains to work but some other time he will just stand still and if nothings happens he will break and endlessly walk backwards but if i was to go near him as he standing still he will reset and continue to work

until he stand still again.....

[dawn gazelle]

Is this is an AoE sphere that applies damage every second to those in its overlap, effectively allowing the actor causing the damage to exist for a little while until it expires? Is it a one-time hits everything like an explosion and then the actor causing this damage disappears?

[pale flare]

i want to make it a one time hit

[dawn gazelle]

Ok, so then whatever is going to trigger your hit (likely your overlap right now) after you apply damage, you'd also want to destroy the actor.
Instead of looping through the actors in the overlap event, instead consider using Apply Radial Damage - this will trigger damage on any actors within the defined radius of the blast.
If you want to go a bit more advanced, you can use Apply Radial Damage With Falloff - this will automatically reduce the damage the further away the actor is from the epicenter of the damage.

[pale flare]

thank youuu

[dawn gazelle]

Where are these values actually used?

[small halo]

which values bro?

[dawn gazelle]

The strafe values

[small halo]

nowhere

they are just called and set in this function

and i am called that function here

https://gyazo.com/19ea8ebe0acae4f22dae4fd65731b2fb

[dawn gazelle]

Nowhere except that you're using them on tick to drive adding movement input 😛

[small halo]

xD

[dawn gazelle]

So in this image, you have a bunch of branches, and the booleans on them are definitely being set true when your AI is detecting the player, but I'm not sure if they're being set false anywhere - and if they're not set false, especially the has target or is strafing, then it's going to continually move in whatever strafing direction it calculates.

[small halo]

My ai is a boss so i want it to continuously to move/strafe around the player

i unlinked all the bools in the event tick so it goes straight to valid node but still bugs out

[dawn gazelle]

So I'm guessing you still have the Add Movement Input connected?

That's where the issue lies.

You're constantly feeding an input into the pawn to move. If you never stop it, then it'll just keep on moving.

[small halo]

ur right.....

i unlinked the add movement input node and now its no bugging out

but i want him to constantly strafe so where would i deactivate it

[dawn gazelle]

Do you want him to constantly strafe when the player still exists but is nowhere near him?

ie. Are you turning setting the Has Target boolean on and off anywhere?

[small halo]

well im spawning the ai in when i enter the room

and the room closes off so the player cant escape

so yeah i guess constantly strafing as the room is also small

[proper depot]

in case anyone hits something similar: I had a loop that was setting the master pose for all child skeletal meshes to that of the parent mesh, I'd forgotten to exclude the mesh that was being attached from the items.

[dawn gazelle]

Sorry, this is getting a bit more advanced than what I can really help with - the issue you were having, namely that your AI was randomly moving backwards forever - is what I was trying to help you with which we have discovered with that movement input. I can't really help you program your AI to perform strafing for you.

[small halo]

no worries

atleast u helped me with my issue

[naive grail]

How i can add a transform to another transform?

[vestal plinth]

you compose transforms by multiplying them
the two operations are compose or make-relative-to
and the order of composition is important

so A * B is not the same as B * A

I think the actual node is "compose" though

[mental trellis]

The "child" transform should be your first input. E.g. component before actor

Is there a way to Line trace from the 8 points of a Actors Bounding Box?

Or is there a way to get each of the 8 points from a Bounding Box?

[foggy escarp]

You could calculate it.

[willow cedar]

How could I do that? I would need the Vector of each of the points

[mental trellis]

Get the bounding box size

Use that to calculate the 8 points and then apply the actor's transform

[foggy escarp]

Can't remember the nodes off the top of my head, but you could use half of the size as the offset in either direction.

[hardy merlin]

Not sure if this is the right channel, but what is the best way to handle a dodge-roll ability for a character? Most examples I see use an animation but I don't have the ability to make or edit animations. I have a few from Frank's Fighter Pack but they're pretty low range.

Well, you have to use anims, so either you make them yourself or buying a better animset.

[hardy merlin]

Can you recommend any?

[mental trellis]

You could use "magic power dodge" and just move your character to the side.

Add some sparkly effects

[hardy merlin]

Question would be how I ensure the character moves in the correct direction overtime without going through walls or launching.

I guess I'll have to disable character movement for a time

[icy dragon]

Or just do a capsule trace sideways and move actor to furthest possible location

[hardy merlin]

Wouldn't want it to be instant

And they would have to roll for the same period of time even if they hit a wall

[obsidian ridge]

Can I do a overlap trigger using a cable component? For example if the end of the cable collides with an actor it triggers something?

[sharp rapids]

Is it possible to Load Streaming Level Instances asynchronously?

There is a Create Instance node but it isn't async

There's also a Load Level Instance, but it also isn't async

[obsidian ridge]

Are cable overlap collisions possible?

[obtuse herald]

Asset gets loaded async anyways afaik

Level asset

Pretty sure I saw an async call in the cpp file

But he can try ofc

If it makes a difference then screw me ig

[plucky fractal]

Have a weapon that has some particles enabled on it for visual effect, but when in equipment menu and equipping the weapon, the particles dont play in the little character preview I have set up.

Tried enabling tick while paused (since the game is paused while menu open). But no dice! Any suggestions?

Cheers

[plucky fractal]

Solution - Add a point light to the particle as a child of it. No idea why this works, lol.

What is the correct way of getting the SaveGame folder? Is it the GameAgnosticSavedDir node?

[odd ember]

I don't know of any BP way to get that. GameAgnosticSavedDir probably refers to /Saved/

[full mica]

Yeah c++ is probably better, any idea there?

[odd ember]

I'm not sure that's exposed to BP. if you have level instances you could try through there but the functionality is limited in BP

[odd ember]

#cpp

[neat stream]

Yo guys is their a way to generate a GameplayTag from a FName or FString?

[odd ember]

did it in cpp

[vague birch]

Anyone got any clue why the right controller and most of left controller prompts don't show up here? I can bind it through the Project settings input menu just fine, but can't call the button directly inside a Bp.

[vague birch]

Someone in here was my hope

[odd ember]

there's #virtual-reality specific for that side of things

[grave relic]

Anyone that can help me with a bit of problem solving? Right now i have a turret that can shoot, it has a fire rate, currently i have to fire rate set up like this. The problem is that i want it to be when my turret has a higher stat in the fire rate, i want it to shoot more frequently. But as how ive set up the sytem if i increase the fire rate it puts a bigger delay on the shooting.

[odd ember]

well yeah, you've made it inversely proportional

[grave relic]

Yeah, but tbh right now my mind has a major brain fart, and i cant figure out how i should redo the system

[odd ember]

multiply it with Deltatime instead

and see how that works

you also have to be aware that you cannot reasonably have an update time lower than DeltaTime

timers always update per tick

[grave relic]

You thinking like this? Or with an event tick?

[odd ember]

so if you have something that is lower than that, you only get more updates per tick, not more ticks

[odd ember]

try that

[odd ember]

also save your handle so you can stop the timer when you need to

[grave relic]

Yes i do, i have a breaker when the turret dosent have a target

It enables fire when it has a target

[odd ember]

sure but not clearing the timer is not good

[grave relic]

Clearing the timer?

[odd ember]

yeah so the timer runs constantly in the background if you don't clear it

[grave relic]

ah ok, so use the "Clear and invalidate timer by handle"?

@odd ember This had the opposite effect så when the attackspeed number is bigger it shoots less often

[odd ember]

2 things: save your handle to a variable on the same execution thread. don't drag pins to operate on different execution threads than they are meant for
wasn't that the first issue you had with the first instance? how can both cases be the same?

[sharp rapids]

That's actually how it would work though
When attackspeed is bigger, it will pass a bigger value into the 'Time' hence shooting the timer less often

[grave relic]

Have it in another function, this is so it was easier to show. I tryed attack speed at 1 and attack speed at 20. When it was at 20 it shoot less ofthen then when it was at 1

[grave relic]

Yes exactly ^^ Need to figure out a way to make it the opposite tho

[odd ember]

the opposite is the inverse. but you said you had the same issue with the inverse?

1/x means the bigger the x, the lower the value gets.

if it works, what's the issue?

[grave relic]

Oh, no i dident mean the opposite that is / meant to opposite of the effect i wanted

[odd ember]

so what effect do you want? because right now I understand it as 1/x gives you the same issue as x * DeltaTime?

[grave relic]

Yeah, i was just dumb, i had x/1 insteed of 1/x when i tested it again, that gave me the wrong results

[odd ember]

in your screenshot you had it correct here

anyway if 1/x solves your issue, I would encourage you to use a max node so you get something like max(1/x, DeltaTime). this will ensure you're never dipping below delta time

[sharp rapids]

You can also have a 'Max Attack Speed' variable and subtract your 'Attack Speed' from that before multiplying it with DeltaTime
That way, when you increase Attack Speed, your firing rate will increase

[grave relic]

Yeah should probly do that, also reduces the possibility of breaking the system

[rotund fern]

I'm really unsure on how to do some things that might seem basic but, then again, i'm not that good at UE5

first, how would one create objects, instances of a bp class, without needing to spawn an actor of said class.
For example, i have a "PlayerAttack" class which has an "Activate" event that does whatever. I can't use the function itself unless i first make an actor and call the event from it...

[remote glacier]

Does anyone know an alternative way of doing this?

The 'get current montage' node isn't showing for me and I've tried to make my own 'get current montage' but have no idea what input and output to put.

[odd ember]

animNotify?

also your animBP shouldn't be referenced in your character or controller

it should only reference them at most

[icy dragon]

Well, spawning the actor is one way to do it.

[remote glacier]

@odd ember what do you mean?

I'm doing exactly what the lecturer is doing and for some reason get current montage' isn't available t

[icy dragon]

In UE5, there's a thing called Modular Gameplay, but I'm still sticking with UE4, so I'm going to assume Spawn Actor is really the way to do it.

[odd ember]

I wouldn't trust a lecturer that serves this kind of code

ask your lecturer for help

[rotund fern]

i would assume that concept is also ported to ue5. could you tell me more about it?

[odd ember]

if you're new to programming and unreal I'd suggest learn.unrealengine.com

[icy dragon]

Spawn Actor -> Save it as reference
Get the reference -> call some function

[remote glacier]

@odd ember tried emailing him but he never answers unfortunately

The only issue I have is "get current montage' I have no idea what input and output type to use

[odd ember]

I can't help you there. I imagine it might be somethign context sensitive or similar. but the code isn't where it should be and is configured in a way that sets you up for fail

so if the lecturer can make sense of it, ask them

[remote glacier]

@odd ember in what way, I'm using this to equip and unequip the weapons, the code isn't complete like I'm future lessons, I've just had to go back to see it

The only get current montage comes as a float and has no return value

[odd ember]

@remote glacier

[woven saddle]

got an interesting bug here, when I link my Anim Notify to a node (in this case, Spawn System) it works just fine, but when I link it to one before (LineTrace) it doesn't fire at all, is this some weird bug or me not functioning?

when I put a breakpoint in the LineTrace it doesn't fire the breakpoint as well

very weird

[remote glacier]

@odd ember I see, just really weird considering it works for him

[odd ember]

that's why I'm saying ask them

[remote glacier]

He's one of those lecturers that provides no support😅 @odd ember

[woven saddle]

I put a print string after the notify and it does fire that, this is very weird, it's like it refuses to do the line trace?

[odd ember]

then I would suggest remaking your code

and follow someone else

[icy dragon]

If you get penalised for remaking the code even if it works, ask for compaint for the lack of support

[remote glacier]

@icy dragon it's not like that, it's through Udemy so not deadlines etc.

I'm so close to the end but it's just this stopping me now

[icy dragon]

Ohhhh Udemy
Now it makes even more sense.

[remote glacier]

@icy dragon sometimes you get support, other times.

[icy dragon]

Quite a few of people said Udemy sucks arse, so yeah

[remote glacier]

@icy dragon it's very good, most of my courses I get a lot of support, just this one is frustrating.

[versed sun]

Is your Udemy course using a different version of UE4 ? i have a Get current Montage node, its just a Pure node

[remote glacier]

@versed sun that's also what I get

I suspect it's an older version

[versed sun]

and you pluged them in and it dosnt work ?

[remote glacier]

But I can't use that node because there's no way to attach to the set

There will be no way to attach it to is valid

That's why I'm asking if I can get the same result but a different method😅

[versed sun]

and you cant do this ?

[remote glacier]

@versed sun I'm trying this as soon as I get home

Been stressing 😂

@versed sun get player character is equivalent to get character ref?

[versed sun]

i think in this case , yes

[remote glacier]

Awesome, thanks! Really close to being done with this course 😅

[versed sun]

I just used it because I didn't have your Ref

[remote glacier]

@versed sun what about the Exec option

Should I just directly attach it to the event?

[versed sun]

they probably changed it in some UE4 version to a Pure node

yes

[remote glacier]

Actually all I need is the return value type and I can create the same function, will have to fiddle when I'm home.

Thanks!@versed sun

[robust harness]

Hey all, I've changed (in CPP) the type of a component assigned to a pawn. In the inspector it's details panel is now empty even though the appropriate UPROPERTY values are set. If I create a new blueprint that uses that pawn type, the component's details panel is displayed correctly. Is there a way to re-load the blueprint?

[icy dragon]

Are you using Hot Reload?
Or compiling C++ code without closing the editor?

[robust harness]

Nope and nope

[odd ember]

#cpp though

[rotund fern]

does anyone know how to stop a ProjectileMovement-based actor? the Deactivate() function of the component doesn't seem to do anything

[odd ember]

the activate/deactivate functions aren't really working in UE

[rotund fern]

Activate works without issue

deactivate doesn't do anythin :/

[robust harness]

Will do

[sharp rapids]

Its pure from 4.27, it seems
https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Animation/GetCurrentMontage/

[versed sun]

I think i remember running into this issue before with bow and Arrows, i wanted the arrow to stop moving when it hit something. I believe I spawned a separate arrow mesh and destroyed the projectile

[odd ember]

this is probably the best way to go about it

everything is smoke and mirrors

[rotund fern]

i see 🤔

[versed sun]

Also, maybe try Stop Simulating, or limit velocity

what to adjust on it

[obtuse herald]

oh

[timber knoll]

In the collision settings on the weapon, set Camera to Ignore

[dusk nymph]

i did but the same issue

[timber knoll]

Then either your Camera is using a different trace, or you have more than one collision on your weapon

[graceful holly]

Working on a platformer right now. What's the best way to approach jumping and dashing mechanic in Unreal? I'm already using the chara component with he built in jump funcionality

[gentle urchin]

Dash -> add force?

[odd ember]

I'd set location over time. that way you can also maintain velocity at balance the speed towards exact values/distances to cross

[sharp rapids]

'Add Impulse' from the character movement component works perfectly for dashing

[graceful holly]

thank you so much!

[keen wedge]

Anyone got a better way of achieving this? Each time I look at the wires it feels like sticking pins in my eyes...

...basically, based on a thing happening, determine which type of thing, then increment the count for that thing... wondered about having one function, but effectively the ++ node is that...

[mental trellis]

That's remarkably neat. Hi5

[keen wedge]

lol...

thanks! 😄

I still hate myself tho! 😄

Is your avator "Orco" ?

[mental trellis]

A neater solution might be set a list of directions in an array and use the enum as the array key.

[odd ember]

or just

a select node

really

[mental trellis]

Mine? It's black mage from 8bit comics. I believe he's based on some FF character? Idk who.

[keen wedge]

(Masters of the Universe - Orco - https://www.google.com/search?q=orco+masters+of+the+universe&sxsrf=APq-WBtH1ABLTCyPF-UiGSylxFFGkJnGMA:1645454794571&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiXwpjkhJH2AhWWiVwKHYD-BSMQ_AUoAXoECAEQAw&biw=1920&bih=977&dpr=1 <-- really similar!)

[odd ember]

not a weeb reference, unexpected

[keen wedge]

how to get the +1 increment using that though?

[sharp rapids]

It's actually beautiful to look at 🙂

[odd ember]

the same way? reduce all your spaghetti down to 1 execution path

[mental trellis]

@keen wedge you're the second person to make that link. Sadly not though. 🙂

[keen wedge]

Like that?

[odd ember]

yeah and hook in your struct

[keen wedge]

(my childhood)

[keen wedge]

like this?

[odd ember]

yep

[keen wedge]

omg... sooooo much nicer!.... thank you! gunna have to get over the fact that one of those two central nodes will be higher than the other in a moment... I'm trying... I'm trying... 😄

[odd ember]

now that should work, but because you're working with structs and setting values inside of structs you may be in for some issues. you'd have the same issues with the switch though

[keen wedge]

oh really? what issues?

[odd ember]

select both the struct and the select node and press q

[odd ember]

structs in BP aren't meant to be written to really

so writing their values might prove difficult

but try it first

see if there is an issue

if not, do nothing

[keen wedge]

ah, ok... I was doing this in a previous project and it seemed to work for that... I assumed they could "contain" data etc?

[icy dragon]

I guess He-man copied Final Fantasy's Black Mage

[odd ember]

you can select the reroute nodes as well and press q

if you select the select node

[odd ember]

pretty sure he-man predates final fantasy by decades

[sharp rapids]

So, you also have OCD about node alignments?

[mental trellis]

Reroute nodes are the best.

[keen wedge]

hehe, no, I just meant that one of those two boxes was always gunna be higher than the other... its fine, I can live with this compared to the previous chaos I had!

[odd ember]

fair

in either case it might be worth pointing out that reroute nodes aren't free

so having less is generally better

[keen wedge]

I will confess to liking things to be tidy/organised, and yeah, tend to use the grid to align things, and get annoyed when I can't position the re-route nodes actually on a grid crossing or in the centre of a grid square... AND... I get annoyed when I zoom out and then all the wires move, and when I zoom in again they dont always retain their straightness....

...so, erm, yeah... maybe a bit 😄

[sharp rapids]

I wouldn't call that Chaos really
Take a look at these (Warning)😅
https://blueprintsfromhell.tumblr.com/

[icy dragon]

I know jackshit about He-Man (apart from that singing and skeletor meme)

[keen wedge]

ooh... not free... do they make calls to what they are attached to or something then? but effectively dont do anything?

[odd ember]

afaik they copy the data the same way as a pure node does

so you get an additional call to the data for every reroute node

[keen wedge]

O.M.G! 😄

[icy dragon]

Wait until you get into situations where the variables have to cross path with each other

[sharp rapids]

Like writing a Macro

No get nodes for local variables 😞

[odd ember]

I'm still of the belief that macros should be shot into the sun

but apparently they have uses

[keen wedge]

hmm, that's good to know... annoying, but good to know... thanks

[icy dragon]

Least it's more used than collapsed node

Also latent functions work in macros

[odd ember]

the loops can stay

[dusk nymph]

thank you i didn't know that every mesh has collision it works now

[slow pewter]

Hey Guys im removing an Index of an Array, then try to Load that Array again, but looks like that Removing Node fucked up everything, when i look into my Savefile its Fine, but looks like it does something strange with that Array

[keen wedge]

I never use them, or at least, I never create them myself.... not keen on stuff that feels hidden. I know you can double click to view etc... but dont wanna...

[icy dragon]

Either you have to deal with it or pay like $15 or $20 to make the splines look like electronic circuit

[odd ember]

very good point

it goes against readability

[icy dragon]

(personally I'm against paying up for something that only end up in the editor only, having no runtime benefits at all)

[sharp rapids]

Which don't look that good either imo

[icy dragon]

Felt like it's not worth the price just for purely cosmetic gimmick as well.

[keen wedge]

Kinda a shame that these aren't features that are just part of the editor... not wishing to screw over the people that make the plugins etc, but if its popular, and useful, feels like a little win to have it as an option at least in the editor... with some customisation...

[keen wedge]

When I saw the electric circuit one I wondered what would happen if someone else opened the project that didn't have it... and if they committed it all back in (having perhaps "tidied" up the wires) - what I'd get again using the plugin afterwards...

[icy dragon]

Or make it (actually) free open source (not just honeypot repos for docs or issue tracker) with paid version in marketplace as a donation.

[odd ember]

just learn #cpp and you'll see your troubles disappearing

[jade sedge]

Anyone know how to save a grid inventory, I have create one and now I like to save or load. But I don't know how to get the items and position of evert grid because isn't like a normal inventor.

[icy dragon]

Teach me how to foolproof asset loading in C++ then

(Except I won't, I'll just let BP handle the asset loading for me)

[keen wedge]

Definitely where I need to be... have years with .net, and c#, ran through a course for C++ a few months back, had always been a bit "scared" thinking it was a lot more than it actually, was... I was pleased to see so many similarities, but the bit I'm not familiar with at the moment is the kinda decorators that Unreal Engine requires to use C++ with Unreal... would love to return to visual studio and leave Blueprint behind me to be honest... probably spend as much time tidying up wires as I do adding nodes! 😄

[sharp rapids]

There's this thing that might be useful, i don't know. It allows straight lines

Double tilde

Working in C++ is okay

[odd ember]

you'll still have to use blueprints, but most of your code can be well designed and tucked away neatly

At least because I mainly touch with C/C++ and not other languages

[mental trellis]

You can go fully c++

[sharp rapids]

Epic LOVES Blueprints afaik

[odd ember]

you can, at the cost of your sanity

[mental trellis]

You don't have to use any BPs

[icy dragon]

It's just that it's the masochistic version of doing things in UE if you don't know exactly what you're doing

[mental trellis]

Learn then. 🙂

You'll benefit from it in the long run.

[sharp rapids]

I wonder If you can actually make a Full Project from start to finish just with BPs

[icy dragon]

I'd rather make my own engine, thank you very much

[keen wedge]

I asked a question about employability with a head of engineering during a web conference thing recently and they suggested the BP was ok for prototyping, but wasn't so useful as C++ when it came to optimisation... thats about as far as the conversation went, but when I look at job ads, most seem to want C++, I dont see very many that even mention BP...

[mental trellis]

@sharp rapids of course you can!

[icy dragon]

If I want truly low level control, might as well go naked

[icy dragon]

Absolutely.

[sharp rapids]

I feel like at some point, you're bound to run into limitations with BPs.
The more I'm trying to go deeper, the more limitations I'm finding out about BPs, which makes me think a full project (a considerably sized one) might not be possible

[icy dragon]

Like thousands of UE4 project before you.

[sharp rapids]

Good to know 👍

[keen wedge]

Funny, it was the "low level" phrase that made C++ feel/seem scary for me originally... seemed to be more talk about memory referecing than I'd ever come across in other langauges etc... henec steering clear, until now.

[mental trellis]

BPs are great if you want to use the engine in the exact prescribed way that Epic wants you to.

If you want to deviate from that, you need c++.

[icy dragon]

That's where C++ come in. You can ENHANCE the BP ecosystem with BP callable C++ functions

[keen wedge]

Yeah, I have... even if only minor things... I wanted to access the "Line Spacing" property on a TextBox (UMG widget)... and it wasn't available.. so had to write a little C++ code to extend it and expose it...

[sharp rapids]

Memory referencing is exactly the limitations that I'm running into right now
I would Love to micromanage memory, but alas you can't do it in BPs

[icy dragon]

Memory referencing, garbage collection, that kind of stuff.

[odd ember]

if you want to use the engine to the limits established by epic's products*

[sharp rapids]

But then it isn't a BP only project

[mental trellis]

You could get around that by writing a separate c++ plugin and pretending, @sharp rapids !

[icy dragon]

But IMHO if I want to go full C++, again, I'd go with making my own engine from scratch.

(And I'm still wrapping my head around DX11 and 64KB demoscene)

[mental trellis]

That's a lot of wasted effort.

[sharp rapids]

I don't have to pretend
I'm fine with C++, just wanted to know if it's possible

[keen wedge]

garbage collection I was familiar with, from my .net days... but yeah, the specific memory referencing etc... seemed a bit alien to me...I also struggle with the need for all the special characters in front of things... kinda like VB.net and C#.Net for just being able to write "words" etc... reminded me of CGI/Perl... which I hated too 😄

[icy dragon]

64KB and less demo prods have been fascinated me, consider that achieving real time renderer in 64KB or less.

Obviously UE can't do that

Unreal is so frickin huge

it's easy to tinker with and get blown up

Guys, what is the best practice for call reload logic, cast on weapon or interface in weapon?

[sharp rapids]

We came from that all the way to now, UE5 😎

why would you want an interface?

can you reload NPCs?

yeah I remember when this came out

but also most of those games are glorified tech demos

[icy dragon]

If anything I felt .kkrieger is more of a proof of concept and not as good as the more fleshed out non-interactive 64k demo prods. (I think it shows)

[odd ember]

I mean it's there to show that it's possible

You can cast on weapon, It depends on what other items you have

But is it actually fun to play though?

No.

[odd ember]

you don't make a 96kb game to make it fun

[icy dragon]

Fun wise, there's not much to be found, but it's still impressive on technological side of things.

[odd ember]

I think it's more of a tech scene thing than it is a game dev thing though

it's just not got the relevance outside of compression algorithms

and perhaps streaming

[sharp rapids]

It might be more suited in the future as the device power increases and they can generate more intricate things, like procedural quests, etc.

[icy dragon]

Okay, snarky jokes aside, if you want to reload, you can cast to the weapon class and execute reload event.

The key is to try abuse the function you made in gameplay.

[odd ember]

there's too much focus on procedural content for what you get a return

hand made quests already are kind of not great

why do people think that AI driven ones will be better?

[icy dragon]

I doubt. It uses lots of CPU to generate all the assets, and eats lots of RAM like a mother to store them all.

Supposedly back then the demo game demands large specs for the time.

[wicked osprey]

Ahh)
I just heard enough scary stories about cast and tried to shove interfaces everywhere😅 😅 😅 😅

[odd ember]

interfaces are more expensive than casts

[icy dragon]

Nah, cast isn't really expensive for "one off" execution

Compared to doing it on tick, it's not bad.

[odd ember]

also really cast cost is only an issue if an object isn't already loaded

[wicked osprey]

But if i called cast on character in every slot in inventrory and other and other classes?

[odd ember]

but in far the majority of cases the objects in question is already loaded

[odd ember]

then yes, interfaces would still be more expensive

[icy dragon]

I'd just do cast on currently equipped weapon.

At least it's for reload event (which on player side, executed in reload action mapped input)

[wicked osprey]

So I did reload the weapon through cast, but then after all these stories I replaced it with an interface, and now I changed it again after your words😅

[odd ember]

is this a udemy course propagating this information?

or is it just because people misunderstand the costing of things?

[icy dragon]

Consider a lesson to profile first before believing into the stories.

And by profiling, I mean benchmarking your own setup

[wicked osprey]

Forum unreal engine...

[sharp rapids]

The latter one

[tawdry surge]

How do you figure casting to ever be less expensive then an interface?

[odd ember]

because interfaces don't exist in cpp

the way epic did interfaces was they made their own version, which is essentially a class hack

[icy dragon]

Also averaging from Unreal Insight if you want your own data

[odd ember]

it uses virtual functions which are always going to cost more for lookups than any cast logic, which is already heavily optimized

[wicked osprey]

Then in what cases is it best to use interfaces? For example, they are only used to interact with actors and to convey information for animation.

[odd ember]

the only case where you could argue it would be cheaper, is if you cast instances that aren't loaded

[tawdry surge]

Everything uses virtual functions in unreal

[odd ember]

but that is an edge case that is so rare I have yet to come across it

[sharp rapids]

Procedural worlds like Minecraft and No Mans Sky are decent enough to keep players occupied
It's not far fetched to think quests could reach a similar level in the future

[odd ember]

absolutely not no lol

[tawdry surge]

I have yet to open a cpp file in unreal and not see virtual all over the place

[mental trellis]

It's a matter of time vs reward. If you want to make something for fun, do whatever. If you're trying to make any kind of money, spending years writing your own engine and being well behind the technology curve isn't going to work.

[odd ember]

interfaces and casts aren't interchangeable in the sense you think. interfaces exist when you need similar logic across multiple hierarchies. so if you need a Use() function for a button, and a Use() function for an NPC, you'd use interfaces

[mental trellis]

I was kinda joking. 🙂

@odd ember I wish people wouldn't call those interfaces, though. 😦 😦

[odd ember]

you see one virtual function in a class and it's all over the place? I'd encourage you to go into #cpp and ask how often virtual is used and how much a virtual function costs vs other functions

[icy dragon]

I mean, I already point out that I'm making my own engine for either demoscene programming or boomer shooter engine

[odd ember]

as in there are better ways?

[mental trellis]

@odd ember No, it's just they aren't interfaces

[icy dragon]

at the moment I have no intention for matching UE for commercial games with custom engine

[odd ember]

as in, cpp doesn't have interfaces?

[mental trellis]

An interface as no logic. It is purely a set of pure virtual functions. They are named badly.

[odd ember]

ah right, the implementation

yes

[sharp rapids]

Ue would be by far the most powerful engine out of the public ones, won't it?

[icy dragon]

Aside CryEngine, yeah

[sharp rapids]

Why isn't cryengine as well known?
It just might be me though

[odd ember]

it is, it's just not as good as unreal

or I should say

it's very good at certain things, but not very good as a generalist engine

if you want to make crysis, it's the best engine

[icy dragon]

But even then Crysis like game is achievable with UE

No matter the heresy

[sharp rapids]

I'll keep that in mind the next time I make a game like crysis

[icy dragon]

Though I assume CryEngine supposedly shines when it comes to open world, compared to Unreal Engine. At least if Kingdom Come Deliverance is any proof.

Also I'd say CryEngine has some nice graphical features UE4 don't have, like SVOGI
(well, UE4 was going to have it, but replaced by LPV at like the last minute)

[slow pewter]

If i remove an Index in Array, like 2, Is The array automatically Resizing that means Index 3, is Now 2?

[odd ember]

have you tested it?

[mental trellis]

Using RemoveAt will shrink the array, yeah. (not necessarily the backing store)

[slow pewter]

Idk it all works nice but if i try to REmove an index, looks like all of my Indexes get Wrong Index Slot

[sharp rapids]

So, ue4 arrays aren't really arrays
They're lists

[slow pewter]

Cant find it in BP

[mental trellis]

How are you removing the index right now?

[slow pewter]

just with "Remove Index", and give the stored Index

from the Savegame file

[odd ember]

have a look at the back end if you're curious

[mental trellis]

That's probably it then.

[slow pewter]

When i just for [Test] Set members in that Array, it Works Good, like [Fake Deleted Name] but when i Removing the Index, its super weirdo, and its like all of my Indexes that are Stored are F up

[sharp rapids]

I'm scared it'll change my definition of arrays

[mental trellis]

Are you complaining that when you remove index #2, that index #5 is now #4 ?

Or that it isn't #4?

[slow pewter]

ITs more Like i have 7 test Widgets / , and its stored correctly at Beginn, [get the Index by Creation Time ] it Works flawlessy, so
1
2
3
4
5, bla bla, When i now Try to Remove 4, with Remove Index, , and save, and Than load again, its , the last 2 Widgets, have the Last Number of the Length of the Array indexs copied

thats super weird

and i cant good debugging my Array, because Ue4, at Debug is a Little Window only

[odd ember]

are you sure it isn't the save game logic perhaps?

[slow pewter]

i checked Savegame

the Stored Thingd are correectly

Only the Indexes, got F UP

and that makes no Sense i just removing Index, and dont , get in touch at any Index, again

[mental trellis]

What happens if you remove 3 elements?

[slow pewter]

lmao, than it works like it should, wth is that xD

removed 345

[spice smelt]

does anyone have any idea what I'm doing wrong? The actor gets successfully added to the take recorder, however the recording doesn't actually start at all.

[mental trellis]

@slow pewter try removing 2,3,4 and see if you are left with 1 and 5.

[spice smelt]

"None if a recording could not be started", no way to see WHY it could not be started 🤔

[slow pewter]

Nope, it copied the last one again in an deleted One [Left is The Index Indicator] looks like it F up
https://puu.sh/IKARb/831a89cd36.png

[mental trellis]

Are you doing anything to the array when you load?

[slow pewter]

Oh lol i figured something out

[slow pewter]

Yes, but When i Delete with that Order 2.3.4 its F up

but When i delete 4.3.2, it works
https://puu.sh/IKASv/0da10f56eb.png

that makes no Sense, i need a Break

[odd ember]

sounds like there's an issue with multiple reorders

[gentle nebula]

If i want to learn how the "Switch on enum" node was made, can i find it in the editor cpp files?

[odd ember]

probably a question best asked in #cpp but yes it's there somewhere

[gentle nebula]

Thank you, i wasn't sure where to ask

[remote glacier]

How can I change it, I'm still stuck and it won't register the 'return current montage'

@sharp rapids do I need to download an older version?😩

[icy dragon]

You can contain it in a BP function, turning it into a non-pure function.

[torpid hound]

UK2Node_SwitchEnum - fair warning it's probably not a easy entry point for UK2Nodes if you've never touched them before

[icy dragon]

As far as C++ is concerned, there's no difference. The only real difference between callable and pure function is that the latter is not executed on its own in BP.

[remote glacier]

When I create a function to match it, the return value sets at "get current montage" when I need it to return current montage

[cold cobalt]

So if I do AttachToActor() is bWeldSimulatedBodies supposed to literally weld the two actors together? Or is there something else I need to do to get that to happen?

[remote glacier]

it's blocking my equip and unequip function from working @icy dragon

[odd ember]

if the bodies are simulating physics you can weld them together using that option

[cold cobalt]

So in the scenario where Actor A and Actor B are both simulating physics... If I attach actor B to actor A, then in theory actor B should just follow actor A around? Am I understanding that right?

[odd ember]

there should be a point of attachment if I remember from the node. attaching one actor to another just means you parent one actor over the other

anyway it's nothing if you're not using physics, for which there are probably better nodes out there

[jade sedge]

Someone know that?

[astral epoch]

Can someone help me figure out how to add bullet spread to this?
I tried following a small guide that involved a lot of making and breaking rotators and transforms but it still ended up firing perfectly forward.

[odd ember]

probably something along the lines of GetRandomPointInRadius combined with (Player.Location - Point.Location).Normalize(), then trace from there

[astral epoch]

In radius for a linetrace?

[odd ember]

you do that before the line trace

and you trace per "bullet"

[astral epoch]

Actually yeah that makes sense now

Is GetRandomPointInRadius correct? Not coming up with any node results when searching

It is an actor component if that makes any difference?

[odd ember]

I can't remember the actual node, but it's something like that. worst case you can make it yourself by doing RandomUnitVector.yz * (Radius * RandomFloat(0,1))

[cold cobalt]

Yeah I'm not simulating physics unfortunately. So, I have a question (and this doesn't have to be specifically for you) what are my options for this specific scenario?

I've got a "drop pod" character that I am spawning in and possessing before it begins dropping down onto the map. Once the pod lands, I want it to open up to show the character in it, and then possess the character. The trouble is, I just don't know how to make this all "smooth".

I was thinking about just attaching the character inside the pod and disabling collision between the pawn & the pod. However, the character just does not stay inside the pod no matter what I try. And I have had some issues with teleporting the character inside the pod after it lands due to some difference in how fast location changes replicate vs. a possess. It causes some jittery camera changes.

[odd ember]

smoke and mirrors

don't spawn the character until it hits the grounds and opens

possess it at that time

in the meantime you can have your pod have a third person camera all the same

[astral epoch]

Tried that approach. Appears to be working, just need to set my arc to something a little more sensible.

[odd ember]

you can then use something like SetViewTargetWithBlend to seamless blend cameras

[cold cobalt]

Ok that makes a lot of sense. I'll give that a shot 🙂 Thanks for the suggestions!

[carmine brook]

Please can anyone advice me how can I reference an object in the BP default?

[odd ember]

just remember if you don't random the radius you'll only get max radius spread

[astral epoch]

0.1 spread

At about 1000 units.

[odd ember]

you can play with the values until you get the spread you want

[astral epoch]

Oh yeah forgot to add a random range

[odd ember]

the method remains the same

[astral epoch]

wait

No I didn't

[odd ember]

you didn't random the range

[topaz gorge]

Hey guys, trying to setup a custom configurator with the tools from the example project and I'm now getting this:

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetActor_ReturnValue". Blueprint: BP_Configurator Function: Call Variant Actor Init Graph: ForEachLoop Node: Branch

[odd ember]

whole point is to random the range so that you can get a variable spread per pellet

[astral epoch]

I used random vector. Hang on a sec

[odd ember]

yes

but that's just for the direction

you still need random for the radius

[thin panther]

you cannot set a default value for actor references

that would go against the point of an actor reference

you can for a class reference

[astral epoch]

Okay you lost me CE but I got something that works

[thin panther]

but not an object reference

[odd ember]

a unit vector is a direction

a circle is a direction + radius length, yes?

[astral epoch]

Right, I was thinking a different solution to what you were suggesting then

[odd ember]

so inside your circle, if you want a random spread, you first need a random direction, and from there a random percentage of the max radius of the circle

[astral epoch]

Mine was just taking the forward vector and adding a random value to the Y/Z

[odd ember]

that's not wrong it's just incomplete

[astral epoch]

Since X would be roll which would do nothing in this case

[odd ember]

no that's not the point

the point is that yz paints a circle perpendicular to the player character

from there, you get random points that you can then trace from

or I guess trace to

[astral epoch]

Okay I think I get what you're aiming for here

[swift kestrel]

Get class default isn't passing my variable value to my inventory system. In my items they automatically get there info from a datatable which is accessed in the inventory by the get class default node.

The item detail variable is getting the correct data. I've checked it with print strings on the items and the correct information comes out. But when I access the variable in the inventory system using the class default all the data isn't there. If I manually set the data in the item details now it shows up.

[trim matrix]

I'm creating a login system, does anyone know if I need to change something?

[carmine brook]

Thanks for reply. Is there any other option how can I set it up? Because after player death, or resting at bonfire the Quest giver would rerespawn and the actor reference, which I need for the quest to function would be gone.

[swift kestrel]

Get class default isn't showing the correct values even in the item class

[thin panther]

could you not have something on the player that records current quest, and when a quest is taken, populate it with the quest giver's reference

[swift kestrel]

Even though the data is going into the variable correctly it doesn't show the data inside the class default unless I manually input it

[slow pewter]

Yeah but the funny thing is, if i only fake Delete it[set it hidden]it Works, so the Index Assign is Correct, only on Remove index i got F up, and that it Works on inverted order , but on Normal order not is really an weird thing

[carmine brook]

I may try it and find out. Thank you 👍

[odd ember]

you can expose and set it in level? I'm not sure if that works for you

otherwise this sounds like a job for a subsystem

[carmine brook]

Yea in level I can set it up. But the actors would respawn during the game and the settings are gone.

[odd ember]

if you are talking about streaming or loading the references should remain as the level spawns with the actors

unless you are talking about killing off the actors and then having them respawn

in which case even then you could use something like delegates to set them up

[carmine brook]

I think I need something like this

[odd ember]

but in the latter case I would definitely recommend a quest manager

[odd ember]

I've never heard of that

is there an example?

[carmine brook]

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/ReferenceAssets/

just reading it...

[odd ember]

okay that is a misnomer

also in truth I'm not sure how that is handled when streaming levels in

[carmine brook]

Yeah quest manager would sure be great. Wanted make the system I just made trough the Youtube tutorial work, but if it will not I will have to make something else.

[odd ember]

or how to ensure that you are only querying that object when it has been streamed in

[odd ember]

the best thing you can do is have a manager that ALL quest NPCs register themselves to

[runic urchin]

How would you go about changing the emissive intensity value on a bunch of static meshes in a construction script. I have bee trying to do it through a dynamic material instance but that is only controlling one object in the blueprint

[odd ember]

BP doesn't really have a great way to handle such an actor, which is why in cpp there are Subsystems. but you could handle it in e.g. game mode

[odd ember]

are the meshes part of the same actor?

[runic urchin]

Yes

[odd ember]

a foreach loop?

[runic urchin]

That should work but I do have static meshes in the scene component that don't have the emissive material applied

[odd ember]

you can check for if they have that material applied to any of their slots

it's another foreach loop nested probably but since you're doing this editor time performance doesn't really matter

[runic urchin]

Not worried about performance so the multiple loops should be fine

[odd ember]

so foreach (mesh in actor) { foreach (material in mesh) { if (material == MyEmissiveMaterial) { //do stuff }}}

[runic urchin]

makes sense, thanks for the help

[topaz gorge]

Hey guys, I can't seem to connect my Configurator blueprint stuff with the actual UI when i click play :/

[formal wren]

This has been asked 1.000.000 times, but how does one effectively make pawn movement speed frame rate independant? I am using FloatingPawnMovement Component and try to multiply ScaleValue by deltaTime but it does nothing 😦 Do I really have to set my Players tick rate to a fixed value?

[jade sedge]

Anyone know how to solve that? Alguien lo sabe?

[supple dome]

thats done when using the move input, in your movement code, for floating pawn thats already multiplied by deltatime, so its already independent

[formal wren]

It is not :/

On lower FPS my pawn becomes faster on higher FPS slower ...

[swift kestrel]

can someone help me with this?

[timber knoll]

This is rotation based on mouse movement?

In which case, mouse movement is pixel based and completely independent of framerate

[formal wren]

I get the world direction of the cursor and move pawn in that direction

[timber knoll]

🤔 well then the movement input literally does that, so you must be doing something else wrong

The scale value should be 0-1 and direction normalized, then it will apply the acceleration: direction * scaleValue * deltaTime

[runic parrot]

Hi everybody! does anyone know if there is any way to stack 2 enums and make a new one with that?

[odd ember]

??

[hollow inlet]

I'm not completely certain, but are you maybe not using a proper movement component? that would explain why things are not automatically working

[gentle nebula]

Is there a simple way to check how expensive things are? LIke adding a certain component, before and after?

[slow pewter]

that sounds wrong

[hollow inlet]

you can always just time how long it takes to add a thing, and print it

if it's just to check quickly, otherwise there are probably better tools built in to UE

[gentle nebula]

Can you maybe reference some?

Like if i want to know how much memory it takes(the component)

[formal wren]

I am using floatingPawnMovement component on my player pawn

[hollow inlet]

i'd just be googling also, i'm kinda new to UE, but for sure the tools exist

[hollow inlet]

maybe those enums should be arrays!

[runic parrot]

I have
Enum 1:
A
B
C
Enum 2:
D
E
F

i want one enum 3 to be Enum1 + Enum2

[odd ember]

can't be done automatically. you would need to manually convert them

[runic parrot]

damn : (

ty

[odd ember]

there isn't. the best way is testing and seeing what you get in return

[gentle nebula]

I am wondering when adding a component should be avoided, like if it's an expensive solution and if i should try to solve stuff in another way

[odd ember]

premature optimization is the root of all evil

[formal wren]

this does the trick:

[gentle nebula]

Are components relatively expensive?

[formal wren]

This maintains the speed I have at 60 fps over all frame rates

[odd ember]

have you tested with 10 fps ? 100 fps? 1 fps?

[odd ember]

depends on what components do. it's pointless to talk about this. you will not know until you test your case

[formal wren]

yes

At 10 fps my game crashes though xD

[native willow]

is this game about what I think it is about?

[white field]

any tricks to combine Actor and Child Actor arrays?

[odd ember]

nope and it's best to avoid child actor components entirely

[white field]

why

[odd ember]

they're buggy and don't perform well

you can just as easy get the same functionality by attaching an actor to an actor

[white field]

hmm

[odd ember]

which also solves your array problem

so there's that

[white field]

lol

well perhaps.. I have been using them liberally though heh

[odd ember]

I would recommend changing that if possible

[mental trellis]

They're probably great for building a bit of static scenery

[odd ember]

you can even attach actors to actors in a level

[mental trellis]

This is true.

Re-usable scenery in a BP?!

🙂

[white field]

why make it static if it's in a bp? 😉

[odd ember]

(you can copy the actor attachment around)

[formal wren]

It is 😄

[mental trellis]

@odd ember Maybe you want dynamic actor attachments based on a BP?! I'm trying to find a use damn it.

[odd ember]

I believe it was created as a crutch 😔

[white field]

well I just went around the whole issue with a tag check sooo

[slender bane]

Why isn't my cave which im creating with a spline not getting a collision? I can still run through it

[white field]

any particular places where they do or don't perform, what's the deal

[odd ember]

it's just overall. they hog memory

[white field]

o.O

[odd ember]

if it's not an issue for you and you haven't experienced that stuff like variables don't set correctly

you're probably fine?

[white field]

well.. it's been a bit complicated at times 😉

but I attach tons of things in various ways heh

it was the old method demonstrated for VR inputs ;/

[jade sedge]

someone know it?

[odd ember]

I mean I've seen people reference animBPs in their player controller based on udemy courses

so my trust levels of anything at this point are low

[mossy valley]

Hey, so I am trying to tie the FOV of my game to the velocity of my first person character, but for whatever reason the velocity is set to 0 when I crouch, even when I am crouch walking around. This causes the FOV to just jump back down to the base value instantly when you crouch. Any ideas why this might be?

[tight schooner]

Anything other than complex collision may scale weirdly when deformed by a spline. Beyond that, just normal collision channel debugging

[willow cedar]

Is it a Smart Idea to use a Blueprint Interface for items that can be picked up instead of Bind event/Casting? I'm just looking for any another opinion/more information on what other options I would have.

[slender bane]

idk why but its only enabling if im setting it at the actor

[gusty shuttle]

Brain farting here, how do I make levels "blueprint load only" style again?

I only want to load via blueprint level streaming

When I press play, all levels load in currently, that's not what I want

aka, how do I get this blue ball next to the name of my level

Also, I don't get that message for "always loaded"

[tight pollen]

will anyone give me an idea how to do this? namely, I have an Array with 40 items and I have a single variable (integer) that can be max 40 and I am using ForEachLoop, how can I make it so that when single variable is for example set to 20, ForEachLoop only does 20 items from the Array?

[thin panther]

Do a for loop

That gives you a max element to iterate to

For each will go through no matter the size

You want a for loop as you can control when you exit and enter

[tight pollen]

but i have 40 images

in array

[thin panther]

That doesnt matter

Why would that matter

[tight pollen]

ok wait

[thin panther]

that will go thorugh your array for however many times you have specified in the variable

[tight pollen]

ok, i understand

thanks

[thin panther]

no problem :)

[odd ember]

you can even use LastIndex which is made for this

oh wait nevermind

it's not an array

[thin panther]

it is an array, they just don't want to loop through the whole thing if i understood

which would make last index redundant

[odd ember]

well lastindex from an array is length - 1

which is the typical case for a for loop to use

[thin panther]

yeah but they dont want to loop thtough the whole thing, they wanted to loop through say 20, of an array of 40

so you just loop through for 20 - 1

last index wouldn't be used there

[maiden wadi]

Dunno. I'd still use it.

Best to say Min(20,Array.LastIndex), avoid some designer coming along and "hurdur don't need 30 of these things in this array no more.

[odd ember]

damn designers, ruining everything

[thin panther]

I still dont think you understand, if they want to loop through the first 20 elements, using last index has no purpose at all

we are going from 0 to 20, not 20 to 40

if that was the case then yeah last index would be perfect

but i dont think it is

[maiden wadi]

Min returns the lower of two numbers.
