[icy dragon]

Question, how do you compile bespoke C++ class?

[faint pasture]

Roll back in version control and see what it was

or just roll back and merge back in

[marsh seal]

[Help] hey everyone, I'm havin trouble with a physics handle.. i can confirm it has a grabbed component and its simulating physics and stuff and i can confirm that my physics handle's SetTargetLocation is going to the right spot.. but i just CANNOT get the cube im trying to pick up to budge.. its simulating physics, obviously.. and it has the collision profile of PhysicsBody

[plain pewter]

Woah time out, now it does open without crashing, but my options for reparenting are super limited. The original class was a ACustomCharacter, I can't reparent it to my custom character class or a regular character.

[plain pewter]

It's just in my project. I can make new blueprints inheriting from that class but I can't reparent this blueprint which I am 100% certain was a child of that class

[icy dragon]

Are you compiling the C++ class whilst the editor is still open?

[plain pewter]

Nope, I rebuilt from VS then reopened the project.

Even tried deleting intermediate folders, no luck.

[icy dragon]

Hot Reload could be sussed out then.

[plain pewter]

Using Live Coding

[icy dragon]

Then more likely your BP asset somehow defect/corrupted

If you have source control rollback/autosave of that file, try reverting to it.

[plain pewter]

alas, i suck at using version control when im not at work.

Guess I'm out of luck

[icy dragon]

Are you deleting the Saved folder?

[plain pewter]

I can try that

[icy dragon]

Don't

Find the autosave file from within

[plain pewter]

there ain't one 😦

It's not the end of the world, it's mostly the c++ class with some assets assigned. I just didn't want to have to replace references to it.

serves me right for not committing in the past three weeks 👉 😎 👉

[jaunty jolt]

How do i add collision to my instanced static mesh in the construction script?

[mellow folio]

Click on the node itself

And look in the details

This is assuming that the static mesh file has collision set up within that file, of course

[radiant pawn]

I'm building a procedural character system and I have a tail spawning on a character (based on % chance), but I can't figure out how to allow it to have physics. Any ideas? It is rigged and has simulation set on the physics asset. (that's the tail sticking out of his head)

[jaunty jolt]

So that means i cant add collision at run time or in the construction script? This instanced static mesh is called StaticMesht10, so thats the file i need to edit and add in collision before run time?

[mellow folio]

I’m not sure what you mean by add collision. Are you trying to set collision settings, or define the shape of simple collision

[jaunty jolt]

my instanced static mesh has no collision. Its a sprite. In the game im moving it using vinterp to, but it always goes through other static meshes
so im trying to make it have a volume, so that it cant overlap others. i just dont know yet if vinterp to will allow that. but i read somewhere that its possible by checking Sweep x

[mellow folio]

You should be able to go to the static mesh file right now and add a simple box collision around it

[jaunty jolt]

and that will work in vinterp to?

ok i will try it. thank u

[mellow folio]

I suppose but that raises all sorts of other questions. Do you want them to run into each other and stop? Are you really sure you want to be using instant static measures that are moving around, This is not usually advised

How many of these are going to be rendering at once

[jaunty jolt]

yes i want them to not be able to overlap each other. but stop, maybe not stopping, but like going around each other. because as it is now they are overlapping and they sometimes go all in the same place, and looks really bad

[jaunty jolt]

thousands. why is it not advised? isnt it better for performance?

[mellow folio]

Maybe, the advantage with instant static meshes Is rendering them. Everything else is a quagmire. Moving them, colliding them, all messy

You might want to fully explain what you’re trying to do, it sounds like this whole system would be better as a Niagara system

[mellow folio]

Have you tried giving the tail the master of the body?

[mellow folio]

Anytime we're doing "thousands" of anything, we'll need to be pretty specific about getting the setup just right

but I'm not familiar with any efficient method for an ISM to "hit" another instance of that same ISM and interrupt movement logic

[radiant pawn]

This worked, but I'm having the issue of the physics spazzing out and flying off into space now lol

[mellow folio]

You're outside my wheelhouse now, sorry. There is an animation channel maybe they know

[mellow folio]

I assume you're using the BatchUpdate node to move them all at once

[sly forge]

Is there a way to actually spawn a static mesh? not adding static mesh component or things like that

[icy dragon]

Spawn Actor?

[sly forge]

an actual static mesh

not linked to an actor in anyway

like the way you drag and drop the mesh in the world

[fading oyster]

Hey, I've had this problem recently where I attach a weapon to the player. The weapon has a collider capsule connected to it, when the weapon is dropped I simply set the physics of the weapon to simulate but somehow the child of the weapon which is a capsule collider stays connected to the player?

Anyone has an idea on why this could be happening? Does simulating physics do something specific thing to its children?

[mellow folio]

You're a bit confused, there is no such thing as a static mesh in the world without an actor.

When you drag a static mesh into the world, it automatically creates an actor called "static mesh actor" which is just a default engine actor

[sly forge]

Yes the origin is actor, i meant the actor we create in blueprints

When i "add" static mesh components they stay rendered even if not in view when i do freezerendering

[jaunty jolt]

Im using Update Instance Transform and vinterp to. I can make them detect other objects by comparing distance on a tick. But something tells me thats not very good in terms of performance.

[mellow folio]

comparing distance to every single other instance?

so if it's 1000 instances, that would be 1 million comparisons right?

or maybe 500,000 if you write it well

https://tenor.com/view/math-calculate-confusing-figure-out-gif-6237717

[gentle urchin]

Atleast use the cheaper distance node :p

Squared one

[gentle urchin]

How is the VInterp looking? Did you do something to get high resolution paths, or do you have issues with clipoing in the terrain? Or did you circumvent this somehow

[jaunty jolt]

Isnt the On Begin Overlap node also checking on a tick?

[gentle urchin]

Ye but thousands of ism with collision would be relatively expensive wouldnt it?

[jaunty jolt]

maybe i should abandon my silly idea of trying to make it with instances. and just make normal static mesh actors 😦

[gentle urchin]

They will be crazy expensive aswell i suspect

But youncannsurely ease down on the ones far away, simplifying their collisions , movement, animation and so on

[lucid lynx]

I'm trying to use SetActorLocation on a timeline to animate an actor going from one location to another over a period of time. It works just fine with static meshes and simple actors like that, but if I use it on a pawn with a collision capsule it breaks if the pawn touches the ground. It's like the second the actor touches something they stop movement instead of sliding along towards the target location.

Is there something related to the collision capsule that would stop movement? I tried disabling friction, but that didn't seem to affect it.

[gentle urchin]

Try changing movement mode

Custom might be suitable for this ? Or flying

[lucid lynx]

Hmm, that was a good idea. It doesn't seem to affect anything though.

[gentle urchin]

Is it a pawn or a character ?

I imagine the cmc doing lots of trickery when hitting the ground

[lucid lynx]

It's a character.

[gentle urchin]

Im not sure if one can simply disable the cmc for a moment ?

Nor if its advicable, never tried it tbh

Worth a shot tho !

[lucid lynx]

Worth a try. Thanks!

[gentle fog]

@faint pasture @maiden wadi It's a node in the Control Rig graph which is used by this official guide: https://www.youtube.com/watch?v=Z8eqaFG7lZQ

[gentle urchin]

Im not sure official is any quality mark at this point

Walking through the Content Examples

Quite weird setups imho

[maiden wadi]

@gentle fogIt's basically a math equation to calculate trajectories of something. Given the context in that video. I assume that it gives that slight bouncy effect to the bones on the Z axis

[gentle fog]

What does the input target mean / do?

[faint pasture]

Yeah verlet is an integration technique that uses 2 positions instead of a position and velocity

Just google verlet integration

[vestal gull]

whats the difference between placing your character model in the world vs placing it inside a blueprint?

[gentle fog]

Yes thanks, I did already Google it 🙂

But normally it does not work like this. Normally you have a particle and the Verlet algorithm changes its position.

But in here I have a target and it seems the verlet is somehow following that target with an internal particle? At least that's how it looks like

[faint pasture]

Show the node and its tooltips, nobody here knows what you're talking about more than you right now proobably

[gentle fog]

ok, here:

[faint pasture]

It tells you what it does right there

[gentle fog]

Yeah so then what does the target do?

[faint pasture]

Target is the position target

this is for a spring/damper interpolation

also use the other one like the tooltip says

[gentle fog]

The other one has the same level of documentation 😦

[faint pasture]

I mean there's nothing to it, it tells you what it does

picture a spring with a weight on it, and you're holding the other end of the spring and moving it around

your hand is the target

[gentle fog]

Ahhhhh

ok, thanks a lot! That makes a lot of sense now! 🙂

[faint pasture]

I used the other sping/damper system for camera movement inside a car. So if you got in a crash it would be like a whiplash simulator.

[vestal gull]

whats the difference between placing your character model in the world vs placing it inside a blueprint?

[faint pasture]

@gentle fogOld and crappy but you'll see how the head bobs around and follows inside the car and has momentum.

[faint pasture]

Everything

Model in world = just a skeletal mesh in the world, no logic to it

a blueprint can have a skeletal mesh and any other component plus logic

[gentle fog]

Ah that's so cool! And it gives me some more ideas on how I can use this effect 🙂

[storm vigil]

LEVEL BP
I have a question regarding level blueprints and how much can it handle to add all stuff.
Currently my game is using it all for all the events like when a door is open or close or someone passes by, it has an event dispatcher this then communicates with other events via the level bp, or when a puzzle is solved it informs the lvel bp, same with objectives and all. So is this alright?
I imagine that all that is happening in my game as it is a horror fps will be written down in the level bp as if it is a story book of all events. So it will be a large collection that i need to organize well.
Is this ok or are there better ways? Thanks

[gentle urchin]

Well it makes for a single location for all things atleast

And its unique per level, and has a requried sequence of events

you could've gone for some overall manager instead, but im not sure you'd benefit much from it really

each level must be set up manually anyways, so reusability isnt very high on the list

doors and such could ofc handle their own logic,

where the level (or another manager) just informs it if it can be opened (assuming it was locked)

or accepting the correct key

personally i'd prob do it that way

So keys have a signature that only fits to that single door

level bp would mostly just trigger events

[storm vigil]

You mean a sort of actor bp to hold the information? I was also looking at how game instance/mode also fits some logic in multiplayer games but in my case its only single player.

Most probably i will only have one level for the game area using level streaming.

[gentle urchin]

doors doing their own logic and animations, and key signatures using tags is prob a cleaner way to go tho

personally i dont like using level bp at all

[storm vigil]

Yup it is setup to use a sort of guid compatible between doors and keys, but once it is open it will have a dispatcher then on the level bp, i call that event to trigger or update some stuff or connect to the obj or some other eventd

[gentle urchin]

Sounds like a suitable place for setting up a global event bus with a dispatcher

[storm vigil]

Thank you for the information, its a simple fps horror game with quests, puzzles, interactive stuff, so i hope my current setup will suffice 🙂

[gentle urchin]

sounds interesting enough (Y)

[open latch]

Can anyone see why this doesn't function as intended

After setting the variable to 55 , it doesn't reset back to 10

[brazen pike]

put the destroy actor last

since its destroyed it cant do the rest

[open latch]

it is a pick up item, so it needs to get destroyed when interacted with ( not after 10 sec)

[brazen pike]

You could do the rest of the code in another BP which gets called. Probably in the gamemode though not sure how feasible it is. Or you could make it invisible with no collision to make it seem like its destroyed when in reality it's still there for 10 seconds

[open latch]

yeah that will not work since the spawned floor + everything on it will be destroyed after 5 sec

[brazen pike]

I mean that you would cast to the gamemode first in the sequence, then it will call an event within the gamemode which sets the point multiplier which goes down after 10 seconds. Then after that is called, the actor is destroyed second in the sequence

You do the destroy actor in the blueprint you sent a screenshot of

but the other code is done somewhere else, that way it can be destroyed and still do the rest since it exists somewhere else

[open latch]

lemme try it 😄

[open latch]

genius 😄

it works

[full mica]

does anyone know the earliest point (or event that fires) at when a widget can be added to a viewport?

[odd ember]

... after the widget has been constructed?

[full mica]

sorry, bad phrasing, earliest point of creating a widget then? there appears to be some game state calls that fire too early to properly add widgets as a slight delay will allow for the widget to spawn and be added correctly

[dark crow]

I can help you learn to take a screenshot if you want!

[polar pelican]

when I add the ocean it comes out red

[odd ember]

after a player controller has been spawned in

[maiden wadi]

Strongly advise you don't use gameplay classes for widget stuff. Best place to handle it is in your AHUD class. Most of the core framework is available by the time HUD's beginplay calls.

[trim matrix]

Hey, is there a way to get total GPU memory usage?

[odd ember]

possibly with the profilegpu console command

[full mica]

yeah I fully get that, makes sense, was just interested in the execution order of the various Unreal components on game start. have been looking for a graph but not found one yet. thanks for your help! 🙂

[odd ember]

there is one

but basically game instance is at the top of the hierarchy for games

actors don't spawn until there is a world

[maiden wadi]

The issue is that it varies based on networking or not. For most UI stuff, the only real things that matter is that GameState is available, and that the local controller is ready. AHUD is spawned by controller, and Beginplay never runs until GameState exists and starts the call to run it.

[odd ember]

and beginplay doesn't trigger before the game mode calls it on every other actor

[trim matrix]

Hello, I'm trying to dynamically change the lyra character's opacity, I'm doing this...
First picture is the blueprint that's run on game's start after team change color (inside B_Hero_ShooterMannequin)
Second pic is the M_Mannequin material
And I've enabled Opacity in all of M_Mannequin's material instances(third picture)
Idk what I need to do to make this work, i'm pretty confused...

The character has the opacity I set on the material asset beforehand, but I can't change it dynamically...

[odd ember]

you have to set it on the node if you're creating a dynamic instance material

[trim matrix]

What do you mean on the node,

[odd ember]

on the node itself, not in the details panel of your material instance

a dynamic instance means you're spawning an instance at runtime

it's not the same as having an instance asset

[trim matrix]

Yes, how do I create the instance at runtime tho, (The first picture is what I'm trying, but it doesn't work)

[low birch]

Anyone have experience with LineTraceByChannel and using Spawn System Attached instead of Spawn Emitter at Location?

[odd ember]

you're using a source material from the mesh itself instead of picking a material you want an instance of

[trim matrix]

this still doesn't work

[maiden wadi]

What is the goal?

[odd ember]

the it's probably something to do with the material itself. ask in #graphics

[low birch]

I was interested in seeing if I could use Niagara Effects (NE) with line tracing but NE wont work with the Spawn Emitter At Location node since it takes particles and not NE. So I came across Spawn System Attached which does take NE.

I've come across a few issues with location spawning and it isn't behaving in the way I want. Either if the line trace hits the world the effect spawns as it should but when I get a line on an actor the effect spawns else where or the other way around.

It's a bit funky atm so I'm just wondering if it isn't a convoluted system to work with.

[maiden wadi]

Not as familiar with Niagara Effects? Is that a new UE5 thing, or?

[brazen spear]

@grand valve Movie Render Queue worked!! Thank you so much for your help!!

[low birch]

Yeah it came with UE5 and we've been able to use it for a while. Just a new way to create effects instead of using cascade.

[maiden wadi]

Still not sure what effects means in this context. What is the difference between an effect and an emitter?

[low birch]

Mmm. Maybe I'm misunderstanding it myself here.

But from what I understand about NE it's a "system" that contains emitters and a few other things. So we are unable to use NE with the Spawn Emitter at Location node because it houses more than an emitter.

So that's where the Spawn System Attached node comes in as it uses a "system" or Niagara Effect.

I am silly and figured it out. Sometimes typing things out gives you the lightbulb you need. Spawn System at Location is what I was looking for. And then you would use NE as the System Template to get the result you want. Tyty.

[open latch]

instead of doing this (first image) is it possible to put all the actors I want to spawn in an array?

[brazen pike]

What are you trying to do?

[open latch]

I have various obstacles that I want to spawn but they should spawn at random at the same location

so currently I only have 1 obstacle (pumpkin) I want to have other obstacles to be spawned at those lcoations as well

[icy dragon]

So which obstacles are random, but they occupy the spawn points one by one?

[open latch]

I have created 2 other obstacles but they should occupy the spawn point but only one can be spawned at any given time

hence why I thought an array would make sense but I am unable to make an array of actors to spawn

[brazen pike]

Yeah, it seems like it would work. A strange way of doing it to me, but if it works it works

[open latch]

how would you do it ? since my method is not working

[brazen pike]

Where are you doing this? Because you're adding a child component when I'd assume that wouldnt be necessary

And how often do you call that ?

[open latch]

inside a function in the BP that spawns the floor/ spawn points. It gets called every time the "pawn" passes a check point.

so this would be the logic for the single obstacle

[brazen pike]

I'd have one actor called "obstacle" which then has its mesh be an instance editable variable which is set in the construction script. Then that actor is created and the variable is set randomly from an array of static meshes in whatever BP you have there

Depending on if you want the randomness to change or not, that would be changed however. If it never changes and is always perfectly random then I'd just have the actor randomly set its mesh on begin play inside "obstacle".

If you want the randomness to be dynamic, then that wouldn't be viable

[open latch]

ok I will see if that works or is even viable for my game

[brazen pike]

Oh, btw you are going to want to change the "min" value to be 0. Otherwise it will always skip the first spawn point

[open latch]

to be fair adding an extra pin to the switch on int would work just fine.. don't know why I want to do fancy 😄

[open latch]

yeah I know I had deliberately done that so it doesn't spawn anything in the middle lane while testing 😄

[open latch]

see second image

[brazen pike]

Well it would be slightly more efficient to do it this way. If you ever wanted to add more objects, then you'd need to go through and add it manually, rather than just being able to add the new mesh into the array and the BP doing it for you automatically

[open latch]

yeah I guess so

would be like 4 obstacles max so it is not that big of a deal I think

[brazen pike]

Whatever makes more sense to you is probably the best way to go

[pliant cobalt]

I'm having an issue working out the best logic for this function, if anyone could help that'd be very appreciated. Squares are static meshes and circles are the materials. The numbers are how many should be in each row. All I'm trying to do is create a function that can generate this without me physically going through and creating a database or something with all the variations then to randomly choose one on begin play.

[trim matrix]

Hello, Is there any way I can reference the material of the body in blueprints?

[teal jasper]

hello i was helping a friend that was having a weird problem in blueprints where each node was way higher that it needed to be, i don't have a screenshot so i did a paint edit to give a reference of how the nodes looked like. do you know what could cause this? An Editor Preferences option?

i think they were even higher than this

[faint pasture]

Create array, shuffle it

[pliant cobalt]

Hero! Great shout

[past hazel]

generated a grid, tell me how can I draw lines between points?

[thin panther]

Please dont crosspost for no reason

[vocal loom]

Hi guys! im just trying to do a simple thing in a blueprint to control a niagara system. Everything compiles and all variables are linked up in niagara, but it doesnt work and i cant figure out why. Any help would be appreciated ❤️

[pliant cobalt]

Clearly there was reason, this is a bp issue so I posted it here after getting no response in general just makes sense

[thin panther]

You waited 5 minutes, be more patient

[odd ember]

have you read the #rules ?

[vocal loom]

awh guess ill keep on crying then 😦 😄

[mellow folio]

Try without the dot?

[mellow folio]

And how do you know it isn’t working

[cyan surge]

Possible to assign the bytes of an Enum manually in BP like it is in C++?

enum class Enum_Character_Action_Type : uint8
{
    // Zero placeholder...
    Null = 0                UMETA(DisplayName = "Null"),

    Jump = 246              UMETA(DisplayName = "Jump"),
    Sprint = 247            UMETA(DisplayName = "Sprint"),
    Deactivate = 248        UMETA(DisplayName = "Deactivate"),
    Activate = 249          UMETA(DisplayName = "Activate"),
};```

[odd ember]

happens automatically, you already have 256 options by default

[cyan surge]

Yes, is there a way to do it manually?

[barren sonnet]

Anyone know of a good way to scale a blueprint actor to the size of another actor ?

[last prism]

Would somebody help me troubleshoot why this Set Timer by Function name isn't working? The function is RandomSkybox, and it seems to me that the skybox would be resetting based on the timer, yet it isn't.

[odd ember]

do what manually?

[torpid hound]

Assign values explicitly, rather than having them automatically assigned to 0,1,2,3 etc.

[odd ember]

I mean you can't do that in blueprint

what you can do in move options up and down

[torpid hound]

So that's the answer to @cyan surge's question 🙂

[cyan surge]

Yep shame really should be possible :')

but I suppose most people wouldn't have a need for it

[thin panther]

Whats the use in having specific enum values rather than 0,1,2,3,4?

Not tryina sound snarky, genuinely curious

[cyan surge]

Because the number actually means something :)

and I have other Enum's with specific values taken you could call it Enum Inheritance haha

UENUM(BlueprintType)
enum class Enum_Action_Type : uint8
{
    // Zero placeholder...
    Null = 0                UMETA(DisplayName = "Null"),

    // 0 - 249 Custom actions, specific to the entity type.
    // See,
    // [Enum_Character_Action_Type]
    // [Enum_Titan_Action_Type]

    // [On Entity]    There is no action active on this entity,
    // [As Input]    Request no change to action, don't apply action input,
    No_Action = 250            UMETA(DisplayName = "No_Action"),

    // [On Entity]    DONT set on an entity,
    // [As Input]    Attempt to stop the current action,
    Cancel_Action = 251        UMETA(DisplayName = "Cancel_Action"),

    // [On Entity]    DONT set on an entity,
    // [As Input]    Attempt to continue the current action,
    Continue_Action = 252    UMETA(DisplayName = "Continue_Action"),
};

// Different types of actions prescribed for all characters,
// Effectivly inherits from [Enum_Action_Type] and expands on it...
UENUM(BlueprintType)
enum class Enum_Character_Action_Type : uint8
{
    // Zero placeholder...
    Null = 0                UMETA(DisplayName = "Null"),

    Jump = 246                UMETA(DisplayName = "Jump"),
    Sprint = 247            UMETA(DisplayName = "Sprint"),
    Deactivate = 248        UMETA(DisplayName = "Deactivate"),
    Activate = 249            UMETA(DisplayName = "Activate"),
};```

[thin panther]

Ah fair enough, that makes sense

[cyan surge]

There's an example of what I'm talking about :D

[thin panther]

Ohhhh i get it, thanks :)

[last prism]

So much activity here, my question is going to disappear quickly.

[cyan surge]

Because your not using it :)

[thin panther]

Its hard to tell whats wrong without seeing the RandomSkybox function

[cyan surge]

that gives you a refrence to the timer, it's the blue "return value"

[gentle urchin]

By using the data you used to create the grid in the first place

[odd ember]

being that there is no numbering for BP enums, I don't really see how you would make that work. add to that you're showing different enums I fail to see how this is anything but an elaborate hack. seems to me that maybe enums aren't really what you're looking for to use

[cyan surge]

If you don't understand you don't need to make a big deal about it bud

[odd ember]

definitely a good way to get help

good luck

[cyan surge]

🤣

[last prism]

Thank you, I'm not totally following what you are saying though. Is that the blue pin off the set function by timer?

[inner igloo]

How do I check if all booleans in an array are false?

[last prism]

This works as intended.

[thin panther]

Then whats the issue

[undone surge]

is there a way to pass different values based on conditons to the FABRIK

[cyan surge]

Probably but it depends what your goal is :)

[inner igloo]

Oh nvm got it

[last prism]

I just want that function to reset on a timer ... it's resetting the skybox.

[thin panther]

You want the timeline to reset each time the timer ticks?

Its doing exactly what youve told it to

Set the timer, rotate the skybox, then every second change the materials of the skybox

[last prism]

It isn't changing the materials, thats the problem. 🙂

[cyan surge]

Try that :)

Pull it into, "Play From Start"

but honestly seems like your timeline is already looped haha

[thin panther]

I dint think you understand the issue

[cyan surge]

I might not :')

I'm like 5% focus hehe

[thin panther]

Is that randomskybox function inside ofnthe sky sphere bp?

[cyan surge]

Okay so you wish to call "Random Sky Box" on the timer?

Then call it from Reset me on it's own

[last prism]

Thank you Lucian! That works like a charm!

[cyan surge]

The classic 5% victory haha

[last prism]

That's true, its why I was asking for insight. 🙂 Thank you! Problem solved. 😄

[last prism]

Roll d100 to understand Unreal Engine ... thanks for helping me make that skill roll.

[thin panther]

Well then lol

[thin cradle]

hey, if I create an actor class in blueprint or c++ that has some component , can I make child classes of that class that replace that component with another component that inherit from it?
ie I wanna make a "humanoid" actor with an inventory component that does nothing, and then 2 inheriting classes, one with an inventory component made for player characters and another made for AI characters, that replace the original class's inventory component

if not, what would be the proper way to do something like that?

[gentle urchin]

This sounds like a strange design choise

Would the player vs ai inventory be different? In what way if so

[faint pasture]

Yeaj that sounds weird. Why different?

[rapid mortar]

Can someone explain to me the process to take a web app designed in unreal engine and be able to use it with a website and application from playstore or Appstore

[torpid hound]

I just 30 mins ago saw a tweet showing that this is now doable with the CharacterMovementComponent in UE5, via a drop down in the blueprint defaults. Might be worth looking there

[thin cradle]

somebody in another discord ended up suggesting having a reference to the inventory component in the base class rather than the component itself
then the child classes would have their versions of the component added, and the reference set to that

[thin cradle]

the player inventory would be part of the save data and would generally be more complex than the AI inventory

think players vs NPCs in dark souls
both human characters with the same base character controller & logic but their inventory work mostly differently

[faint pasture]

Then make player inventory a subclass of ai/chest inventory

I prefer just one component though.

[barren sonnet]

Does anyone know how you can have a construction script show up in the details panel when its inside a component on a blueprint?

[gentle urchin]

Not sure you can

[odd ember]

how would you have it show up?

[barren sonnet]

Ah dang...

normally if you check the call in editor box it shows up as a button in the details panel.

[odd ember]

... yes?

the construction script already runs everytime you move an actor or change a value

[barren sonnet]

issue is if you make it a component instead of a blueprint and added it into another blueprint the property doesnt show up unless you make another construction script that casts to the component.

that is the case for most but it seems like the editor apply spline action im using doesns't work like that.

[odd ember]

it should

[barren sonnet]

It doesn't automatically paint the terrain as I move the object around

oh interesting. hmmm.

[odd ember]

I don't know what you're making but it sounds like you're trying to do something that's not allowed

[gentle urchin]

Painting realtime at editortime sorta thing

You can play in editor,

Detach,

[odd ember]

with splines though?

[gentle urchin]

And paint by calling the function

I painted with splines 😄

[odd ember]

I can understand making a landscape brush

I just don't know where splines fit into that

[gentle urchin]

It was for rts road

In my case atleast

[barren sonnet]

yeah in my case I'm trying to make a component that lets me paint dirt on the terrain around builds using splines.

I have the spline in the building blueprint so I dont have to make the spline every time.

[gentle urchin]

So you only need the building extents, and follow along that^^

But same idea anyways it sounds like

Paint along a given path

[gentle urchin]

Be it a spline, a line or something else

[spark steppe]

is there a way to predefine the datatype for arguments in the Format Text node?

[odd ember]

hook in a literal

[spark steppe]

e.g. i want ${FOO} to always be an integer node

well thats one way.... i hoped for a solution like in the math expression node where you can force data types

[gentle urchin]

Wrap it in a function

:) not as nice but nice enough :p

[spark steppe]

yea i guess datatypes are not the idea of that node 😄

as it seems to be a exposed feature of FText rather than a standalone node

[odd ember]

it's an analogue of how you do text in code

first time I hear someone not liking generics though

[spark steppe]

i use it to generate an SQL query, so it would have been nice to define the correct data types :>

[odd ember]

why not use build string then?

text is for formatted text

string is the type you want to use for cultural invariants

[spark steppe]

build string seems like a mess, with the format text node i have the whole query in one line which makes it more readable

[odd ember]

normally good practice for SQL queries is divide them up into several lines

[spark steppe]

well, i'm not too much of a fan of any of the solutions in BP either

but also not motivated enough to port it to c++ for now

as i don't even know if i want to keep it SQL related

[odd ember]

I mean really if you're doing something like calling SQL queries I'm not sure why you aren't working in cpp

[vocal loom]

sorry for the lkate reply! ive put a breakpoint, it hits it but it isnt affecting what im trying to control

[spark steppe]

that's some old relict of my project, which was before we had rider on linux 😄

and therefor no suitable IDE

[odd ember]

sounds like you're hellbent on shooting yourself in the foot 😅 I have no answers to that

[floral zenith]

hi, does anyone know of a way to make a sphere collision able to pick up multiple instances of an actor? I got a character with a working function that reveals hidden objects inside a huge sphere collision. I want it to reveal all the hidden object inside the circle at the same time, but it seems it only picks up one at a time.

[odd ember]

show code

[floral zenith]

it works, but it only picks up one object at a time

all of those actors have the same function w/the particles

[lusty rune]

How can i make to always check branches?

[odd ember]

okay so. I'd delete everything after the cast

is this inside the player character?

[floral zenith]

no, this is inside the actor blueprint

[odd ember]

explains why you're having issues

[floral zenith]

the sixth sense is just a bp with a sphere collision that attaches itself to the player character

[floral zenith]

how could i fix that

[odd ember]

well you're enabling input on each of them, but realistically it would have to either fire on either all of them, or just the last one. and I think in this case it will only fire on the last one.

you kind of have to think about it differently

instead of having a separate actor for the collision, I'd just have a collision component directly on the player character

any time that collision would overlap with one of your objects, I'd add it to an array

inside your character you already have free access to input events. you could then use the array that you have to consider what you want to do with the bulk of the objects

do you want to do something for all of them? for just one of them? for a specific subset?

[floral zenith]

I want them all to show the particles whenever the player is pressing F/Y/Triangle to indicate that he can interact with it

[odd ember]

how does the player know which one they are interacting with?

[floral zenith]

there's another collision box for Interaction, he stands beside it and a widget pops up to show what he needs to press and how (press, hold, mash, etc.)

[odd ember]

okay so all you want to do is some activation

how does the second interaction work?

I'm asking because right now the code that you showed enabled interaction too

[floral zenith]

The activation for the interaction works when the player collides with the interaction collision, a gate opens that enables him to press X, then he presses and the function is called

[odd ember]

yeah but it was on the same event

so the same collision

[floral zenith]

they got two

[odd ember]

okay but you only do the logic on one event

not two separate events

[floral zenith]

i got two events, top one with the Sixth Sense collision activates the particles when pressing Y. The bottom one with the Interact Collision activates the actor function when pressing X.

the problem lies with the top one

[odd ember]

like I said, your approach is flawed

I would avoid using enable input

and handle input in the player character instead

then you also only need one event

and none of this spaghetti gating

[last abyss]

disable that

[floral zenith]

okay, sorry about that, I got confused. So remove the enable disable inputs, and every time the character collision overlaps with the object's collision, add it to an array?

Sorry for the spaghetti codes, im kinda new to this

[odd ember]

yes, an array inside your player character

then you have your input actions, hint and interact

also in your player character

now you have an array of elements you know are nearby (inside of your sphere), so you can do things with them

let's say you want to interact with the one the camera is facing

you can now do that for cheap

meanwhile, if the hint action is affecting all of them, you loop over the array and activate the hint on each of the objects

[floral zenith]

oh

i think I understand

I'll do that then, thanks a lot CE 😄

[flat coral]

I've got a bit of AddForce on a weapon fire and of course most of what I hit isn't movable, because it's just level geometry. What's the cleanest way to check if a hit actor or component is "Movable"? I can't find a method that supports it

[odd ember]

another thing: I notice you have some delay functionality. I'd advise for you to make a hint event inside of your objects that handles any delay activation and deactivation

much simpler

then from the player character blueprint, all you do is call that function, and the object itself knows what to do

[floral zenith]

will do, thanks for the help

[floral zenith]

yeah, i think learning through youtube might've caused me to adopt a complicated way of doing much simpler things :C

you're a lifesaver

[odd ember]

youtube tutorials are a very easy way to paint yourself into a corner

it's people who don't understand programming who are the first to put videos out

so it's the blind leading the blind

[faint pasture]

Any ideas on how to implement an item system that leverages GUIDs?
That is, an item system where every item is unique, that would enable a lot of gameplay regarding insurance, registration, investigation, linked items (phone contacts) etc.
GUID in the item struct at creation is a given, I'm more wondering about how to implement an ItemActor or Item lookup given GUID, for gameplay purposes (tracking an item, messaging from one phone to another, etc)

[flat coral]

Also what's the difference between "is simulating physics" and "Is any simulating physics"?

[odd ember]

isn't there a GUID system available in cpp? otherwise it would probably not be difficult to make one based off the asset name

[flat coral]

There's GUIDs built into UE4. But if you wanna do it between different devices, things get considerably more complicated

[faint pasture]

Yeah you can just generate GUIDs all you want. I'm talking more of the registry or backend or whatever you'd call it. Some sort of global master data serverside that knows where every item is (what inventory it is inside or where it is in the world) etc.

[flat coral]

Oh man you've asked the right guy lol but it's not Blueprints at all

What you need is like a REST API with a backing datastore of some sort

[faint pasture]

Global as in per server instance, not global as in the entire game across servers.

Could just be a map of GUID to.... what? I'd think InventoryComponent or InventoryID but that doesn't cover the "in the world" case

[odd ember]

I don't think that's a question for #blueprint. if you want it to sit deep in the core, there is no way but use #cpp

[flat coral]

So if I'm getting this right you've got a central registry that can say "this item is on the ground, coords XYZ" or "this item is in the inventory of Player 3" or whatever?

What happens when that disagrees with your world state?

[odd ember]

crash to desktop

no trial

[flat coral]

https://tenor.com/view/jail-right-to-jail-right-away-parks-and-recreation-parks-and-rec-gif-16177531

[faint pasture]

Yes exactly. I moved to #c++ but "This item is in X inventorycomponent or is instantiated as X Actor" is the basis.

[odd ember]

someone gets the reference 😎

[flat coral]

I mean blueprints have full GUID support as far as I can tell. But I'm still curious, you want to make a secondary tracking registry for things which are (in theory) already tracked.
Like if an item is in a level, the game knows that. If a character interacts with it, and it's removed from the level and added to some inventory list, the game knows that. But you want it to know it twice, in two different locations.
Why? What happens when they disagree?

[faint pasture]

Moved to #cpp since its kinda in that purview.

[flat coral]

Oh interesting. You can defs do that all in BPs. You just need to define a top-level abstract object all your items are going to inherit from. And probably a "Activate in world" and "Activate in inventory" function

[flat coral]

The cellphone use-case is a great example actually. In theory "activating" a cell phone in my pocket and one lying on my desk does the same thing, it rings and I can answer it right? But in practice, the "hows" of that interaction, how do you display that it's ringing other than the sound, how does the player interact with it, how do you message that interaction potential to the player, those are all completely different on an in-world item and an in-inventory item.

[cobalt gulch]

How could I make it so variables stay the same when switching maps?

[earnest tangle]

You have to store them somewhere between level changes

GameInstance is usually the only thing which doesn't get destroyed during that

[cobalt gulch]

oh

So I put the variables in gameinstance?

[earnest tangle]

If they need to persist between level loads yeah

Level streaming is another option, in which case some actors may not always be destroyed between streamed levels, but it has its own complexities

[cobalt gulch]

The variable im using is to show the cash the player has, would I need to save this to a file somehow?

[earnest tangle]

Well if it's just one variable it's pretty easy to store it into the game instance temporarily during level loading

[cobalt gulch]

Could I make it with a save file?

[dark crow]

You could save it in a save file indeed if you want it to persist after closing the game and coming back

Indeed

[cobalt gulch]

Is there an easy way to do this

[dark crow]

Just save? :D

There are nodes for it

[undone surge]

how would i make a projectile type for a shotgun in which there are multiple meshes that spawn out in a cone shape?

[maiden wadi]

You're looking for SaveGame Objects. You should make your own class for it and then you can CreateSaveGame, LoadGameFromSlot, and SaveGameToSlot

[dark crow]

https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/SaveGame/

https://www.youtube.com/watch?v=_4usRrTiqak

[cobalt gulch]

Thank you

😛

[flat coral]

Why can I set default variables for a child actor in the BP editor, but not in a scene?

[faint pasture]

Use your normal projectile system, just spawn 9 of them instead of 1

[undone surge]

aaah

is there a node to repeat it 9 times? @faint pasture

[faint pasture]

For loop

[undone surge]

ok thnx

[faint pasture]

make sure you give them a slight variance each loop or else you'll spawn 9 projectiles in the same place with the exact same direction. Not really what you're going for I think

[undone surge]

yes

ill use random

[winter kettle]

is this blueprint node the some as this option in the details panel?

[undone surge]

@faint pasture i managed to get multiple projectiles spawning but now what nodes do i use to tell it to orient them to angles after they spawn from the muzzle ?

[dusky topaz]

I'm at my wit's end here, I'm rebuilding a project, and I can't seem to get the same usage of interfaces working in the new project. First picture is an example from the old project, just a reference to a generic Game Instance, and using an interface message from that. The second picture is what I am currently struggling to figure out why it doesn't work, it's the same type of setup, generic Game Instance and an interface message, but the second one isn't going through. Anyone have an idea of what the issue could be?

[brisk sinew]

Does your game instance implement the interface and know what to do when it receives a save data message?

[faint pasture]

Spawn them pointing in slightly different directions

[undone surge]

how do i specify the angle

like rotation node ?

set rotation or smth

[faint pasture]

yes, a transform is made up of location, rotation, scale

[undone surge]

ah

[faint pasture]

so combine the rotation of the muzzle with a rotation with small random pitch and yaw values and it'll be MuzzleRotation + SomeSmallOffset.

[undone surge]

ok thank u

[dusky topaz]

It does, this is what I have setup in the Game Instance

[scenic kindle]

i know this is a somewhat dumb question but... how do you open level blueprint in ue5?

[maiden wadi]

Pretty much the same way you did in 4.

[scenic kindle]

?

[undone surge]

@faint pasture i have this one transform pin i think orange do i add a node in between that and the socket transform to specify the angle ?

[scenic kindle]

ooooh that's what that is. mine just has the icon. thanks

[thin topaz]

Can someone kindly tell to a beginner, what is this blue icon here in the blueprint node?
(I'm trying to re-do my schoolwork but I don't remember what I did for this to appear and I did not find any in documentation or by clicking on it)

[dusky topaz]

Ah, of course, I had forgotten to specify which Game Instance class to use for my game mode 🤦‍♂️

[dusky topaz]

It's showing you that you're watching that value, if you breakpoint in the blueprint, that should show the value of the input directly in the graph

[thin topaz]

Thank you for this fast help. I totally remember now!

[brazen pike]

if you break the transform connection (alt + left click) you can right click and split the value into smaller parts. That will give you rotation specifically. Then you feed everything else in normally but specify what you want

[undone surge]

@brazen pike i got to that part , how do i randomize a rotation? im running a for loop i want to set it to spawn at a random rotation evey iteration

this stuff is after the loop

i just want to know how to tansform the random node to rotation

[brazen pike]

What do you want rotated, just the Z axis?

[undone surge]

like i want it in a cone

[brazen pike]

so it is looking left/right a random amount

[undone surge]

like a spread

[undone surge]

and up down

[brazen pike]

Okay well you can use the "make rotator" or you can split the rotator again. Then you can feed in a random float in range to the values you want randomised

So you'd want the Z and Y axis randomised but not the X axis otherwise it will spin

you probably want to feed the X axis from the get socket transform into the new X axis

[undone surge]

i see

but how do i get it to get a random rotation ?

[faint pasture]

Why would you use integers

[brazen pike]

use "random float in range" rather than "random integer in range"

[undone surge]

ahh

i see

i think i got it

[brazen pike]

You could use integers, but only if you wanted them to be whole numbers or specifically within 90 degree variations or something

And then connect it to both the Y and Z but have the X be taken from the get socket transform

[undone surge]

did i do it right

[faint pasture]

No because the muzzle rotation never factors in to this

[undone surge]

oh

[faint pasture]

combine your random rotation with the muzzle rotation to get muzzle + variance

[undone surge]

i see

ill try that

[gentle urchin]

The value is added to your watch list, which you can then inspect without having to step through all the nodes in a bp 🙂

[brazen pike]

Oh this is a gun

[undone surge]

how do i combine ?

[faint pasture]

Have you tried? Just drag off a rotation and type combine, you'll find it

[undone surge]

oh ok

[maiden wadi]

I use blenders. Much quicker.

[faint pasture]

huh

[undone surge]

@faint pasture @brazen pike am i missing anything here. its working but just in case im making any mistake

[maiden wadi]

Logic is very literal. It's unlikely you have a mistake if it's working as intended.

[faint pasture]

You don't need to split the pins on combine rotators, just combine the rotators as purple pins

[undone surge]

o i thot i had to do it because i was gonna leave out x

if its 0 then it will leave it out regardless right

[unreal quail]

is there any painless way to keep a bunch of variables queued with a delay?

all I want is to say call an event 3 times, which has different parameters every time and then keep the parameters while it's going through delays

[gentle urchin]

you can always add it to an array

and iterate that manually, in whatever delayed sequence you want

[unreal quail]

I want each to have different delays though

[gentle urchin]

right so thats a parameter

[unreal quail]

I thought delays were linked to the event instance calling them

except this gets overriden every time it's called with a new value

[gentle urchin]

Yeah you'd need more sophisticated logic than that 😛

[unreal quail]

https://media.discordapp.net/attachments/603649974042886296/804409299517571092/image0-19.gif

[gentle urchin]

Array is the que

On first entry, start the delayed loop

[unreal quail]

how does that Delay work when it's called multiple times btw?

[gentle urchin]

Ignored while "active"

[unreal quail]

https://media.discordapp.net/attachments/603649974042886296/804409299517571092/image0-19.gif

[gentle urchin]

so keep them in a list,

first entry is read directly,

next entry is read after a variable delay from the first entry

something that says something about the first entry's duration i suppose

[undone surge]

im trying to blend this bone depending on the bool but when i do the animation my character just stays still. is there a way i can get it to stop blending for the duration of that bool being true?

[lament geyser]

is there a way to make programmatic curves in BP? I'm basically trying to make a curve where my keys are variables

[unreal quail]

ah yes

blueprint

[bold shard]

I have a FString var on my character, and I set it to some text in my BP, but when I try to use it I always get an empty string. I don't know how to fix this.

[barren sonnet]

Anyone know of a way to trigger a construction script on any actor in the current level that has a specific tag ? Tried this but its giving a warning and isn't working

[bold shard]

According to your warning, your spline comp is not an actor, so the cast will always fail. You probably have to do GetAllActorsWithTag->GetComponent->CastComponent

My data seems to be disappearing between getting and using it. Anyone have any ideas?

[faint pasture]

When that print is hit it'll get again

[bold shard]

I think I am doing something wrong, but I am not sure what. I tried setting the value right before calling this print string, it still comes up as empty.

[barren sonnet]

That worked, thanks @bold shard !

[potent laurel]

how are you trying to use it

[trim matrix]

hi guys

i have a question

[potent laurel]

😄

[trim matrix]

guys how do i create an ai i have been strugling to figure it out

[thin panther]

Theres an ai quick start guide on the docs

But it all depends what ai youre tryina male

Make*

[trim matrix]

just one that walks around for now

[thin panther]

Then look on the docs for the ai quick start guide

[trim matrix]

and i dont wanna use a tut bc i wont learn from it

tutoirals = for morons who want to copy ppl

[trim matrix]

ok ty

whweere do i find the docs?

[thin panther]

Just google ue documentation

[trim matrix]

ok

[remote belfry]

Does UE5 still have a level BP? Google is garbage lately, and I can't seem to find it. As well it's probably right in front of my face and I'm just blind, stupid, or both. lol

NM

[trim matrix]

I am both blind and stupid. It's the new BP icon

[trim matrix]

im blind

[thin panther]

Just google ai quick start guide and youll find it

[trim matrix]

ok

[bold shard]

I am spawning my character then trying to use it as a key to a data table.

[trim matrix]

i think i found

[potent laurel]

could you screenshot the flow of events

[bold shard]

PortraitName is configured on my character BP

[potent laurel]

are you sure the return value from the spawn function is going to the set name function? it looks like its passing through under to something else

[bold shard]

The value of PortraitName is set on the BP, the Name I am setting there is just for the UI in my gym.

[potent laurel]

also you could set the "name" function in your character class to "expose on spawn" that way you will have an input node on the spawn actor function

also it looks like there should only be an a and b node

(should have crossed out c)

[bold shard]

I was just using that " | " as a way to separate a couple of inputs

And sure, I will try exposing it on spawn, but doesn't that defeat the purpose of configuring my blueprint?

[potent laurel]

its the same thing no?

[bold shard]

Not really.

Configuring my BP lets me use the same data package everywhere I have my spawners.

If I need to give my var the ExposeOnSpawn tag, then I will need to configure my spawners to handle my different character types, and pass different PortraitName vars in each case.

[potent laurel]

does the logic on the pawn have functions for that?

[potent laurel]

understand

what class are you spawning the character from?

[bold shard]

My spawner class

[trim matrix]

wait a sec guys i have a question

how do i make a better aiming then my current one?

let me load it up rq

ill send a ss

[potent laurel]

ok, i see you set the playerchar as a variable omn the TEMP_addchar event, could you set that variable straight after spawning it instead

[bold shard]

Its like none of my character's data is persisting after spawn

[thin panther]

thats a very open ended question

define better

[trim matrix]

i can explain better when i get the screen shot

wait just a sec ok

breh my map makin skills are just 👍 😉

[bold shard]

I could, but this leaves me with the same problem of "How do I define which portrait to use?" If my blueprint data is being reset after spawning it, then how am I supposed to know which portrait name to use? Any data I set on the BP to set my PN will be reset as well

[trim matrix]

by magik

[potent laurel]

then you set it from the player char variable you made

"get"

[bold shard]

The data is being defaulted when I spawn the character, so that won't work

[trim matrix]

here

[bold shard]

Any data I try to access off the return is whatever the default value for the variable's type is. String and names are empty, data tables are null, etc etc

[trim matrix]

instead of just set fov to - interger like how do i get it so it aims down sight?

[thin panther]

can either be done with animations or an ik setup

[bold shard]

You probably want to set that bool to true on press

[thin panther]

ads either requires you to make an animation that brings the gun and arms to the center of the screen

or you ccan use an ik setup and do it programatically

[trim matrix]

ik?

[thin panther]

inverse kinematics

[bold shard]

[trim matrix]

oh

i have 3 brain sells

would it work with this model sort of

[thin panther]

well ye

[trim matrix]

thats what im workin with lol

[thin panther]

but youd have to set it up

[trim matrix]

bc ik how to do that 😉

[thin panther]

you need to either animate it, or set it up for the ik process

[trim matrix]

f*ck animations

too hard for meh

[thin panther]

if you wanna make games you better get used to em 😉

[trim matrix]

well

not when i am have 3 brain sells

also one last thing

oh no 2

1: when i shoot the front of the guns goes to the left slightly

do ya know why?

[thin panther]

probably an animation thing

looks like you're following underscore's tutorial

[trim matrix]

who da f*ck underscore?

who?

[thin panther]

youtube tutorial guy

uses a similar looking set up for his fps tutorial series

[trim matrix]

ye

[trim matrix]

f*ck me

most fps tutorials do

[trim matrix]

true

[thin panther]

but anyway

[trim matrix]

i can legit change the gun to my own one i made in blender

rn

brb

[thin panther]

better aiming is either gonna require you to learn how to animate, or do some not-so-easy math with ik

[trim matrix]

im rly gud at mmath 100%

how do i stop my bullet bouncing?

[thin panther]

uncheck bounce in the projectile

[trim matrix]

ok

nothin there

[elder mango]

how can I make it so the fps template uses my own mesh instead of the default one?

[trim matrix]

ez

[elder mango]

and the animation still works

[trim matrix]

click on the thingy

[thin panther]

ther will be something in projectile movement for bounce amount

[trim matrix]

then the otherone

[trim matrix]

ok

[elder mango]

bc when i change the mesh the animations stop working

[bold shard]

Your mesh probably has a different skeleton than what the anims target

[elder mango]

so do i need to add the default mesh skeleton on my mesh?

[bold shard]

That idk, I don't work with animations. I've just had the same problem before, so I know what a potential cause is

[trim matrix]

holy i just made my reload so much beter

[flat coral]

Uh so is there no BP function to filter an array by any condition OTHER than class?

[dark crow]

Well yeah, if it's a different mesh with a different skeleton you need your own AnimBP or if it's a similar skeleton type you can retarget the animations

[elder mango]

how do i retarget the anim

i have the same skeleton

[trim matrix]

wait

so guys

iv added a grenade to my game

tbut could i

You can iterate over the array, and filter out the elements you want in the loop body

[flat coral]

"Max Grenade" is my new gritty action OC

[elder mango]

lmao i pressed control z too much and ue crashed

[trim matrix]

e?

[flat coral]

What do you mean by "max grenade"

[trim matrix]

like

so you can only throw like 3

and you cant use anymore

bc rn u can just spam c and crash my laptop

[bronze hill]

hello can i ask something about blueprint in here?

[dark crow]

Yes

[faint pasture]

It's #blueprint so, yeah.

[flat coral]

I mean... that's probably its own separate set of problems

[bronze hill]

ah thank you! i wonder why event dispatcher Custom Event binding node has Execution pin?

[trim matrix]

yh but if i put a max cap on it

[bronze hill]

i know that when it called it fire custom event but why node itself has pin?

[flat coral]

You could also just put a cooldown on the grenade ability

[faint pasture]

Show screenshot of what pin you're talking about

[dark crow]

Cause it will execute the code when the listener is called?

If you mean the one coming from the red square

[bleak swift]

Easy way is make a variable and do a check before the rest of the code to check if the variable is above 0 and then -1 each time a grenade is used

Easy Way

[bronze hill]

here!

[dark crow]

Oh no no

That's to continue the flow of the code

Imagine if you wanna have 3 listeners for example

[faint pasture]

That just binds the event to the dispatcher then goes on to do something else.

In your case, you're binding the event then setting percent. If that's what you want to do, then great.

so, in your case, Set Percent will fire when the widget is constructed and whenever the UpdateHealth dispatcher is fired.

[flat coral]

Here's an example of when I'm using ONLY that pin

[bronze hill]

Thank you for your kind explanation. So the order doesn't matter?

[flat coral]

Well, it can, but to answer a slightly different question the order of binding does not influence the order in which the bound functions are executed.

[trim matrix]

how do i make explosion bigger?

[bronze hill]

ok i understand

[dark crow]

I think it's a blocking thread when setting the bind, so should be fine in any order

[faint pasture]

Scale stuff up.

[trim matrix]

e

[flat coral]

That SetupInputBinding function I linked is called on BeginPlay and happens instantly, and then the actual code is executed whenever the player presses the associated keys

[bronze hill]

As long as the event works, can it be placed anywhere?

as i understand?

[thin panther]

why do you just keep saying e

[faint pasture]

What do you mean "placed anywhere"? The only real structure to the order of events and nodes is the execution flow.

[dark crow]

Usually binds are set on beginplay / construct / init unless you doing something special

[trim matrix]

bc my brain hert

[dark crow]

Really depends on what the bind does

[bronze hill]

sorry for my bad english, I mean anywhere in execution flow?

[rare star]

Hi, just a bit stuck, how can i get the location of an object i just spawned? i don't know how to reference it

[dark crow]

I would personally place the binds at the start if you need them to listen asap

[flat coral]

When you spawn an actor there should be an out pin that has a ref to the actor spawned

[bronze hill]

ah ok thank you guys

[faint pasture]

I mean sure but things will happen in order from the entry point of the chain (whatever event is triggering it)

[bronze hill]

all of you have nice day!

[bronze hill]

i think that event dispatcher binding event only fire when it called?

[flat coral]

Yeah creating a binding is kind of like you're making a road from one thing to another. And then later on, someone can drive down that road, one or multiple times.

The idea is to mentally separate building the road from driving down it. They happen at different times

[trim matrix]

ahh i need help

[thin panther]

with what

[flat coral]

The questions you're asking so far have been a little too general for what people can contribute to, without like teaching you how all of UE works. It'll help if you can link some specific code you're having trouble making work

[thin panther]

^

[flat coral]

and being specific about what problems you're running into

[thin panther]

your issues so far come with a lack of understanding of the engine, and the tools that go with it

i highly suggest picking up a beginner course

[trim matrix]

nah i got this trust

[reef marsh]

has anyone run into issues with UE5 not using your PlayerState class?

[trim matrix]

i think i got this now

[reef marsh]

I'm using a subclass of PlayerState but it isn't being used, even though it's set in GameMode

I'm not sure what teh deal is

[dark crow]

Who knows with UE5

But how do you know it's not actually being used?

[reef marsh]

ok, so it's the game mode not being used

which means the rest isn't either

maybe the level is overriding it

[dark crow]

Did you override the GM in the World Settings or set in the Project Settings?

[reef marsh]

project settings

ok, that did it

geez

don't nkow why I didn't think to check that

I thought my PS was messed up

[dark crow]

We've all been there, dw

[reef marsh]

haha, thanks

[trim matrix]

i sleep now gnihgt

[faint pasture]

OK can someone tell me why I'd choose using DataAssets over DataTables?

I'm pretty firmly in the DataTable camp but I'm sure theres something im missing about data assets.

[mellow folio]

People are worried about memory

You basically never want to have hard references in any data tables

Because if you reference any part of the data table you have to load all of it

[faint pasture]

So what would the equivelent of AllItemsInTheGameDataTable be in DataAsset terms?

Can it just cruise to a folder?

[mellow folio]

So people like to use data assets instead so they Can load up some hard references that they want

Not totally sure, I’m also a table guy

[faint pasture]

I've seen a lot of stuff about data assets having functions but ew, OOP is gross.

[mellow folio]

I’ll take a look when I get back to my computer

[manic knot]

Any idea how I could get Trace 2 to Begin trace at the Impact Point from Trace 1 + x units With respect to the Walls Orientation instead of the player?

[faint pasture]

Hit Normal

[rare star]

thanks, issue is it seems to give me the location right after it spawns, but doesn't update on tick

[manic knot]

would this be how I get Hit Normal + 20 units away from normal?

[faint pasture]

Yeah, normal is away from surface tho so you'll want -20

draw a debug point there and look

[thin panther]

whats the difference there between impact normal and normal

[faint pasture]

Mouse over and it'll tell you.

I think they're equal for line traces

[thin panther]

ah fair enough, just not in ue right now

[faint pasture]

but ones the normal away from the surface, and the other is in relation to the shape that was swept

[thin panther]

that makes sense

thanks :)

[scenic kindle]

hey i have a problem
I'm trying to make a system where you can select a perk to use in-game using this gui.
However, when I try to save this specific perk, it sets the "has perk" value back to false.
It only happens for this 1 button. It doesn't happen for the first one even though the blueprint is the same, only the values are different.
is this a bug or something cuz i can't figure out why.
The issue happens after pressing the green button.
number 1: the value in the player blueprint before pressing the button
number 2: the value in the save game before pressing the button

number 1: the value in the player blueprint after pressing the button
number 2: the value in the save game after pressing the button

the blueprint for pressing the blue and green button (blue on top, green on bottom)

any ideas?

[potent laurel]

try promoting the created save to variable

[scenic kindle]

so i wouldn't have to create a new save game object?

[dark crow]

Seems like a lot could be wrong, be sure the values out of Player Data are correct in the first place

[scenic kindle]

they are, in the first picture, the value for player data is true, when i press the button, it sets it to false for some reason

[dark crow]

Show that logic of true and false

[manic knot]

Ah I got it now! Location + ( Normal * x )

Thank you!

[scenic kindle]

here's for number 1

and here's for number 2

[potent laurel]

it could be how your loading the save maybe

(after)

[scenic kindle]

the save is loaded at the beginning of the level. it's perfectly fine except pressing the button somehow sets the variable to false and i have no idea why

and it's only that button even though the blueprint is the exact same for the blue button also

[dark crow]

Cause PlayerData is false

[scenic kindle]

but is shows true in the first picture before i press the button

[potent laurel]

your exiting function after 1 loop

[dark crow]

But if you press the button and in text 1 it says false, means it's false from Player Data in the first place

So it's gonna store in the save false too

[scenic kindle]

from player data, it says true

when i press the button, it changes player data to false even though i didn't tell it to

[mental trellis]

You might be getting the CDO of the class, not your instance, where the value is false

[faint pasture]

Why is player data an actor?

[dark crow]

So it's something in Player Data then if it returns false in the first place

[mental trellis]

Doing "Get All Actors of Class" is very bad. You really shouldn't do it.

[potent laurel]

how many playerdata actors do you have

[dark crow]

I hope only 1 lol

[faint pasture]

I mean its not all that bad if you need to do it but this is not a need to do thing he's doing right here.

[scenic kindle]

i didn't want to store it in the player blueprint because I use different character blueprints and i want the same values for each of them

[potent laurel]

using for each loop is causing your problem maybe

[dark crow]

There's Get Actor of Class too for just 1 Actor in case

[scenic kindle]

just 1

[faint pasture]

Why is PlayerData not stored on PlayerState?

[mental trellis]

The proper use cases for it are so small though!

[dark crow]

It's not my code :D

[faint pasture]

It's good enough for GameMode, it's good enough for me.

[mental trellis]

Heh.

[mental trellis]

Then store it on a game instance or osmething.

[faint pasture]

if the thing you need is all actors of a class in the world for some setup, it's fine. If they're from the level loaded from disk, it's like, the only way to do it.

[scenic kindle]

another interesting thing is why only this one button is broken. why does the other one work fine? it's an exact copy

[potent laurel]

the other one is probably 1st in the loop, before you exit it

in the function i screenshotted

theres alot that could be causing this lol

[willow cedar]

Is there a way to change variables of Character movement component through another actor component?

[faint pasture]

Yes.

Just get the component, change the variables.

[mental trellis]

@willow cedar yes

[potent laurel]

yes, "get character movement"

[mental trellis]

Is too slow today

[scenic kindle]

i'll try saving it a game instance and see what happens

[dark crow]

Indeed, would make no sense to have more than 1 in the first place, and it's kinda bad that's it's an actual Actor

[willow cedar]

Thank you!

[willow cedar]

And you!

[willow cedar]

And you

[potent laurel]

😄

[mental trellis]

And my axe!

Or something

[willow cedar]

I had the idea right, I just didn't have the name to look up correct

[dark crow]

You have an axe? Cool!

[viscid hinge]

it keeps repeating

its getting detected twice any idea?

[potent laurel]

could be the event your firing it from

[dark crow]

Are you updating from a tick?

The Do Once makes me think that

[viscid hinge]

yes

[potent laurel]

can you trigger the entire thing from a different event

[dark crow]

Make it Event Driven instead

Like a Overlap to trigger it

[viscid hinge]

if i remove the do once it gets screwed up

il show you

[dark crow]

I know

Move it from a Event Tick

[potent laurel]

^

[viscid hinge]

idk why the collision is detected more than once

[dark crow]

Use OnComponentBeginOverlap

[potent laurel]

its not using a collision

^

or Event on hit

[viscid hinge]

that part is in c++, i did use Onbegin overlap and called it using an event in bp

even before i had the same problem

i sent here it

[dark crow]

Check if it overlaps the Pawn only

[viscid hinge]

what pawn, im using a charecter

[dark crow]

That works too, lol

[viscid hinge]

well it does overlap, it prints, its just doing it many times

watch the video

[mental trellis]

A Character is a Pawn.

[viscid hinge]

after one hit

[dark crow]

Are you still on tick?

[viscid hinge]

yes, thats what i have it on, thats the only way i can do it in c++ or generaly, how else will i do it

[dark crow]

Overlap

[viscid hinge]

yes

[dark crow]

Indeedo

[viscid hinge]

so whats the problem

[dark crow]

That you're using a tick

[signal orbit]

does anyone know how i could find the "physics" node when i right click and search?

https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/8/7/787791ef386dface7ab1fc9a3e49b67d7d885692.jpeg

(image was sent to me by a colleague, i'm trying to copy the code but i can't find the physics node 😦)

[dark crow]

Looks like an Actor

Just called Physics

[potent laurel]

@viscid hinge

[dark crow]

I always used the dispatcher button for it :D

[potent laurel]

wheres that lol

[dark crow]

Details

[potent laurel]

try get mesh

then search physics

[potent laurel]

ah yeah lol

[dark crow]

I think what's happening there is just a class that was saved named as Physics that contains a Skeletal Mesh Component that gets accessed from it and the Physics set on the Component

[signal orbit]

thanks you two, that actually makes sense. i'm creating a cinematic and one of my characters gets shot. i don't have any "death" animations to work with so i'm just trying to make the character ragdoll and add some impulse from the bullet.

[potent laurel]

yeah

[signal orbit]

i've never worked with physics before so i'm crossing my fingers this works.

[dark crow]

Physics is the Character then

Char ref

[potent laurel]

yeah, someone has made it confusing for you lol

[signal orbit]

😕

i'll probably find a way to call the event using sequencer's event track

🤞

[viscid hinge]

Bro I have this already but in c++ only different I’m calling it bu event which the event is on component begin overlap

[potent laurel]

ok

this is from ut4 lift

[eager agate]

anyone know if theres a way to convert text to static mesh? im trying to make it so that when the text box is committed a mesh will be set to whatever object is referenced.

[thin panther]

text and static meshes are 2 completely different things

you could maybe set the text attribute in a 3d text actor

but you cannot linearly ocmapre the two

one is words, the other is a group of vertices and a material

[eager agate]

i just wish there was a way, if the written text was the name of a valid static mesh

[thin panther]

can you not just make a list of valid actors to change it to instead

[dark crow]

DataTable / Map

Would work

[restive token]

Add a switch on string. Then you can make pins that say “cube” “sphere” etc, then on each pin, you tell it “set static mesh name” to the mesh you want, then connect all to that last node you have

[dark crow]

Pretty messy if you need to expand on it, Imagine adding a pin for every addition

Automate with a DT where Row Name is the Static Mesh name and have the Row hold the reference to the SM to spawn

[eager agate]

alr alr ill try that

[dark crow]

Text = Cube
Row Name = Cube

Row holds returning SM to Set

So you can make entries and in it and never touch the code for every addition

[scenic kindle]

Thanks to everyone who helped with my issue. I have concluded that it was in fact a bug because it worked as soon as I remade the entire blueprint. And thanks for the suggestion to use a game instance it is a lot better than storing the variables in a "dummy" actor

[potent laurel]

maybe soft reference?

[eager agate]

wdym?

[thin panther]

dw thats not how soft refs work

[eager agate]

kk

hmm is there a way to create a data table to switch blueprints 🤔

[thin panther]

a soft ref is like a normal ref, but instead of being a pointer, its a location on disk where the asset is, so to use them you have to manually load them, which reduces a bit of overhead sometimes

[thin panther]

wdym

[eager agate]

nvm

[thin panther]

all you need to do is use that text to get a row name

and then get the static mesh from the row

and use that in the add static mesh

[potent laurel]

never really used them, i thought thats what it was

you could just use a structure too

[thin panther]

nah basically it's a way to prevent loading lots of things

say if i have a data table, with 100 static meshes,
if i use hard refs, it loads all of them when i access the table which is big memory chunk.

soft refs mean you can just load the specific one you need and use it

[eager agate]

yup im using structures to make a data table

[thin panther]

soft refs would actually be really good in the case of what you are doing

[eager agate]

how could i do that

[potent laurel]

?

[dark crow]

When you decide the class of the SM there's gonna be Soft Ref

Cyan color

Object is Hard ref

[thin panther]

if you make all of the data table refs soft refs, and then when you get the soft ref in the bp, plug it into a load asset node

then that gives you a hard ref to plug into add static mesh

basically prevents you loading every single mesh in that table into memory when you just want 1 row

first time ive seen someone here that can benefit from soft refs ngl

[dark crow]

Be sure to use the Completed exec pin tho when you Set

Node is called Async Load Asset

It's Async so doesn't block the game thread

[eager agate]

this is all very confusing to me but ill search on how to do it more... i think i under stand what youre saying

[dark crow]

It's really the normal workflow, but you put the Async Load in between Getting and Setting

[eager agate]

okay

[thin panther]

yeah its 1 extra node really

and it will help you a ton

say if you decide to expand that to 200 possible meshes

the without soft refs, whenever you access the data table, all of those meshes, materials and textures get loaded into memory

which could be hundreds of megabytes of ram

instead soft refs just store the location on disk, which you manually load, meaning you only ever use 1 at a time

which would be only kilobytes

[dark crow]

Just don't use if it something is already always loaded no matter what

[thin panther]

yeah

[cobalt gulch]

How can I create items which players can have but without using many variables

[thin panther]

its mainly useful for data tables

[cobalt gulch]

Is there a list of some sort?

[thin panther]

that is a really vague question

why dont you want to use many variables

early optimisation is a no no

you gotta remember that most of these variables are like 32 bits, so its no biggie

[dark crow]

32 bits is like double of 16, that's a lot!

[thin panther]

obviously if your item needs 200 texture 2ds then there is a problem

[dark crow]

But yeah, depends on what you mean by your statement

Vague

[thin panther]

but you need to be specific, what items, do they go in an inventory, do they not, what do you mean by the player can have them, why are you avoiding variables

cause spoiler without variables you cant make things

[dark crow]

I already see the 100 variables manually added to an Array with Make Array...

[thin panther]

thats just good coding tho

youre just jealous smh

[dark crow]

I am, cause I don't have that level of patience :c

[thin panther]

(this was a joke for legal reasons)

(if i see you do that i will scream)

wow accidentally the same character number
