blueprint

[foggy tiger]

I tried to have a look at AISenseConfig but not much resources^^

[topaz gazelle]

I'm using a blueprint with a skeletal mesh as the root component (it's a rifle). I'm attaching that blueprint as a Child Actor Component to another blueprint (the character). I can't seem to find a way to access the blueprint's variables (rate of fire, damage, etc) since it's being referenced as a Child Actor Component instead of as an Actor.

[lunar sleet]

You can use the built-in friend or foe system, I believe it’s called IGenericTeamInterface but you’ll need a bit of cpp to do so. Same with gameplay tags. Also use #gameplay-ai for these questions next time.

[foggy tiger]

Oh thx a lot! Noted for the tag sorry for that!

[lunar sleet]

Np, only to say that you’ll get answers from more specialized people

[boreal crypt]

Is there an existing function in blueprint that can convert rotator degrees to be 0-360, instead of -180 to 180?

I can add one easy enough, but if there is an existing one that'd be preferred

[lunar sleet]

Clamp axis iirc

[boreal crypt]

ah! clamp! thanks that looks to be what I need

[lilac storm]

hey devs . i have downloaded asset from marketplace and starting to notice this type of strange variables , what is this ?

[lunar sleet]

Child actor components are broken af. Just use regular actor components

[topaz gazelle]

Need it as a skeletal mesh component, just trying to compartmentalize information where it makes sense. Might as well put information about the rifle where I'm using it to attach to the actor.

"Get Child Actor" and casting it works.

[outer quail]

how do I make it grab once it will +1 the SpeedCount variable? I'm doing a ship throttle, so when I grab once it will move the throttle to speed no 1, if grab again it will move to speed no 2, etc. For now without the SpeedCount variable, the throttle only move to turn on and off

[lunar sleet]

I don’t rly understand your question but I only see a Set SpeedCount to 0, no +1

[outer quail]

yea I want it to add up everytime the throttle is grabbed

idk how make the + counter that would change the speed count

[lunar sleet]

Set counter to counter +1

In other words, GetCounter, add node with 1, SetCounter with the result

[calm bloom]

Hey guys, is there any way to get the instance static mesh that is spawn by an actor using line trace?
So i have BP_Room actor that spawn in the walls which is instance static mesh and i want to detect the specific wall the line trace hit.
Currently it just return the room actor

[outer quail]

like this?

[lunar sleet]

You can also clamp it so it doesn’t go past a certain number if you want

[outer quail]

nicee thank you

[distant hollow]

Check if you have set up the collision in the static mesh correctly

Or if something has already blocked it before it hits the static mesh since it’s green

Also you have two traces running (two red lines) spit is kinda hard to tell if it’s resulting from the line trace behind your character

[calm bloom]

This is the current collision box. And the line behind the character is the same thing but just spawn by another actor. And the result is the one from the front which is expected

[distant hollow]

Try playing around with these

I would also get the name of the source of line trace just to be absolutely sure as well.

[topaz gazelle]

Why are you using Get Class if you want the specific wall it's colliding with?

[calm bloom]

was just following tutorial but it still return the room itself without class

[topaz gazelle]

Do you want the mesh that's being used or the wall that it's hitting

[calm bloom]

the actual wall it hit

This is the wall that get spawn by the room actor

ahh nvm im dumb. I forget to remove the collision on the wall themself. Im actually spawning in the wallCollision at the wall location

fyi im just following tutorial. Not sure if this is the best way

[topaz gazelle]

Easy to overlook.

[calm bloom]

thx anyway guys

Do bound events always execute in the order they were bound? So if you need one to execute before the other you'd need to bind them in a different order or have more events to distinguish more points in execution flow?

[echo storm]

For some reason when I capture the scene on all my SceneCapture2Ds using the Capture Scene node, my FPS drop really low and stay at around 10-20 FPS and the console gives me the following warning even though none of my SceneCapture2Ds capture every frame

[outer quail]

Hi, I'm making something like a cctv using render target. But when I attach it as material to a static mesh it becomes blurry/zoom in

[distant hollow]

It should probably triggered based on order of trigger event
So say if you bind event A and event B
But if you triggered EVent B then A then it should follow the latter

[wild crater]

Yea but I mean I bind several events to one dispatcher. Then I would guess they always execute in the order the bindings were defined?

[distant hollow]

Hmm

Then that I am not so sure

[wild crater]

I guess I'll have to test it. Would be cool if you could set a priority though. Ah well

[distant hollow]

"Event Dispatchers in Unreal Engine use a multicast delegate, and the order of execution is determined by the internal implementation of the delegate system. Each bound function (event handler) is added to a list, and when the dispatcher is triggered, the bound functions are called in an order that might not be predictable based on the order of binding."

If you need to ensure a specific order of execution for multiple events, you may want to consider alternative approaches:

Sequential Dispatching:

Instead of binding multiple events to a single dispatcher, you could create a sequence of dispatchers where one dispatcher triggers the next. This way, you have control over the order of execution.

Custom Logic Inside a Single Event:

If possible, you might combine the logic of multiple events into a single event handler and then trigger that single event. This approach allows you to control the order of execution within the event handler function.

Dependency Management:

If the events are dependent on each other, you might implement a system where each event handler checks for dependencies before executing its logic. This way, you ensure that certain events only run after others have completed.
Remember that Event Dispatchers are often used to decouple systems and provide a way for different parts of the code to communicate without direct dependencies. If the order of execution is crucial, consider using other mechanisms like function calls or custom signaling systems where you have more explicit control over the flow of execution.

[silent drift]

Anyone happen to know how I can "suck" the player towards a special point?

I want to create a projectile that stops at a location and then start pulling the player towards it.

[vocal spoke]

May I butt in with quick question?
Say, I have a ActorComponent that needs to perform a procedure at set intervals - what would be more performant way of implementing that, having the object tick with a reduced, manually set, tick rate, or have the object's ticks disabled and regularly setting timers for, say, 1s intervals?

[brazen pike]

Timers are typically used. That way you can set a handle and invalidate it at any time

Also allows you to use tick in the future for something else

[vocal spoke]

Sure, but assuming I am sure that this object does not need tick for any other reason, and thinking of performance only - is there any impact to either solution that should be kept in mind? I feel like being able to set the object as canEverTick=false is a gain, but then again the timer manager has to measure the time anyway somehow...

[distant hollow]

This may help

[iron kindle]

has anyone dabbed with making sliding fps mechanic like the slash from quake champions ? would love to be pointed to a tutorial or guide for anything remotely similar

[random pulsar]

hey mates,i want to make the character hit the simple block and to turn his phisics on and when he hits it again to destroy it,how can i do this?

[silent drift]

Thanks!

[random pulsar]

now he hits the block and it simulates physics but how can i check it one more time?

[cursive grove]

Anyone good with vectors?
I've made a spiral spline going upwards, but I want it to follow the main spline. Do I have to change the vector's direction at distance along the main spline? Or how is this done?

I think I just need to change the up vector to forward at every point in the spline

[outer quail]

I tried to use BPI if the right throttle is grabbed/activated. Then I tried to call it in Propeller blueprint where if the throttle is activated it would spin. But I'm confused on how to use the bpi

[spice viper]

The BPI has to be implemented somewhere, I'm guessing in your propeller BP. If you add the interface to that BP you'll then get the functions associated with "Throttle Activated" & "Throttle Deactivated" where you can implement your propeller specific logic like spinning or whatever

[outer quail]

so the bpi should not be implemented in the throttle? or I should add set in the class setting for the propeller too?

[spice viper]

Looks like inside an ABP, I'm assuming those are nested values inside structs? So in this case I'd assume the struct is "Swimming" and that struct contains a location variable or float variable named "Delta Location"

[spice viper]

Sort of, the BPI defines the concept of throttle. The BP (likely propeller) sets what the functionality of Throttle does. The BPI is like an outline, no actual logic happens there. On the blueprints you want to do something with that behavior is where you'll implement the interface.

Here is an example from my own project. I have an interface "Glowable" that says an actor can glow and get it's color. It's up to each actor to implement how that happens.

[trim matrix]

What's the point of multiple event graphs? To organize stuff, mostly?

[spice viper]

Pretty much, same with a "collapsed graph"

[outer quail]

Alright, I will try playing around with it, thank you

[heady burrow]

how do you create a variable inside your class of type function?

so when I create the actor I can pass a function as callback

cant find a way

or maybe there is a different way to do it

[undone sequoia]

guys how to make collisions for skeletal mesh which will copy its surface? like it s possible on static mesh but I have to use skeletal mesh because I had to animate it

[wide smelt]

hey here comes what might be a daft question. how do i rotate my lyra character from blueprint/code?
i've tried setting world rotation and using teleport
context: i possess another pawn and attach my lyra character to this pawn.
i then repossess the lyra character and want to have it face the same direction as the pawn.

[latent junco]

Hey, got a conceptual question: Does it make sense to split core game functionality over multiple BPs? Say I have a strategy game, do I want a ResourceManagerBP, a UpgradesManagerBP, etc. that handles only that, or is it better to consolidate functionality in as few BPs as possible?

[hot ibex]

Hello, I'm trying to apply a simple 0/120/0 rotation but Unreal recalculates the rotator to 180/60/180

Is there a way to avoid this ? I wanted to do an "animation" where it gradually rotates by an angle when triggered

I tried with both World and Relative rotation

[gusty junco]

Hi, not entirely sure where to post this.
Does anyone know of a way to avoid having to rotate decals by -90 degrees on the Y axis to align with meshes that have Z up? (the floor)
It's really frustrating having to deal with this when scaling blueprints with decals non-uniformly 😦

[spark steppe]

most likely, no since rotation is stored as rotator which may do weird things
also is your initial rotation really 0,0,0?

[distant hollow]

If I am not mistakened, if you repeatedly set Relative rotation on the same value it will rotate constantly.

[hot ibex]

yes it is 0,0,0

[distant hollow]

So it wouldn't matter if Unreal recalculates it

[spark steppe]

they are setting the rotation, so there isn't even interpolation going on here

[distant hollow]

Breaking it up is more scalable.

[fickle quartz]

You can either manually input a combination of box, capsule, and sphere collisions in the skeletal mesh's physics asset that roughly conform to the skeletal mesh, or turn on the "Enable Per Poly Collision" box under Skeletal Mesh -> Advanced. Per poly collisions are very expensive, though, so I would only recommend it for low poly assets.

[distant hollow]

Input/Outputs on the function

[hot ibex]

ideally I want to use a lerp to have a smooth rotation, but applying 120 again would not make it rotate

apparently it only recalulates for X/Y , incrementing on Z is fine,
I think i'll just rotate my initial mesh and use Z 🤔 , weird but might work

[heady burrow]

no I mean, to create an actor and as a one of the exposed variables to have one of type function that I can use as a callback later on conditionally.

[distant hollow]

I’m not understanding you. Give an example scenario?

[heady burrow]

Sure, in my game there is a tile system where some actors would exert influence on them, meaning, the tiles will be marked in a way that when other actors exist inside such tiles, something should happen.

Sort of, the actors would listen for other actors when they put a foot on specific tiles.

[distant hollow]

Sounds like Binding and Event Dispatcher

[heady burrow]

Yeah I've read a bit about that, it sounded a bit convoluted, passing a function as a parameter looks cleaner. At least thats how I implemented it in my previous engine.

So I was surprised when I didnt find a way to have a variable as type function.

maybe in C++ is possible?

[distant hollow]

Never heard of a variable with such a Type before

[heady burrow]

its very common to have variables of type function.

[distant hollow]

Well personally I have never came across one, can’t help you there

The closest I could think of is having a dispatcher call and trigger the event on the other side

[heady burrow]

yeah Im not very familiar with how dispatchers work, maybe I should look into it

are they related to delegates in any way?

[distant hollow]

The Dispatcher can always carry an input to pass itself over to the Binding side

[distant hollow]

Delegates like in Unity? Yeah probably similar

[heady burrow]

no in-engine.

[distant hollow]

I did a bit of reading up on Delegates, it may sounds like what you were actually looking for

[brisk rain]

quick question, i realised counting every tick up by 1 makes the result vary, but if i have:
every tick: variable = variable + delta time
will it count the same in every device? (like after 10 seconds the value will be the same not depending on frame rate)

[heady burrow]

yeh

[distant hollow]

Yes, DeltaTime is meant to take out the tick differences

[brisk rain]

alright thx

[fickle quartz]

I'm making a game where you play as a mosquito and I want the player to be able to land on various AI creatures (humans, ground animals, birds, etc). I want all creature types to be able to move around the environment and change their behavior if they become aware of the player.

I tried making the first AI creature a Character BP to take advantage of CharacterMovement, but the mosquito was unable to walk on it... I think this because of the properties that Characters come with by default? I also tried making a basic Pawn BP with the same skeletal mesh and was able to walk on it, but I can only use FloatingPawnMovement on that BP, which is much more limited in functionality.

Is there a way to make it so my mosquito can land on a Character BP, or do I have to find a workaround with the Pawn BP?

[spark steppe]

try the "Can Character Step up on" setting in the actor blueprint of your character

set it to "yes"

[trim matrix]

why my while crashes my game?

[spark steppe]

because it never exits

remove the whole while loop here

[trim matrix]

so do i need to connect something to the complete?

[spark steppe]

no

you need a condition which will change it's state within the while loop body

[fickle quartz]

I tried that, no luck 😦 I set it so the capsule isn't blocking the player pawn at all, and the mesh can be stepped up on, but I just keep bouncing off of it

[hollow cove]

hey guys why would loading game from slot cause unreal to freeze. doesnt crash just freezes up.

[fickle quartz]

The mesh has properly configured collisions from a physics asset btw

[sturdy thistle]

Are you async loading or sync loading?

[hollow cove]

sync loading, but it should be fast to load this is the totality of the stored variables

[sturdy thistle]

It does sound like something is holding up the load time

[spark steppe]

maybe you got to change it in your mosquito, too

[sturdy thistle]

Maybe try with a async load

[dry sleet]

But if it freezes the blocking load entirely then async will just hide that issue, probably

I assume you mean it freezes completely, not just hitches?

[hollow cove]

yeah, cant click or do anything. havent tested past a minute if it unfreezes

[sturdy thistle]

Ah okay then its an entirely different issue, I assumed you mean a minor hitch

[hollow cove]

im checking if it exists to see if thats the issue, made sure all the variables have default values...

[dry sleet]

You're sure it's the loading operation, not some processing you do afterwards?

[hollow cove]

absolutely just the load game from slot node. removed everything else

[dry sleet]

huh!

And you're not opening a new level or anything in the process?

Sounds strange

Neither the Load from Slot nor any casting done afterwards should cause it to freeze.

Is everything pure Blueprint?

Could it be I/O?

[hollow cove]

just checked nothing in the widget was causing it, not that either

[dry sleet]

If something is preventing unreal from accessing the object on disk I guess that could result in some strange behavior.

[hollow cove]

i did move some files around recently, could be that i guess but i cleared all the saves and made a new test one since then

[dry sleet]

Hm, sorry, beats me -- sounds like nothing I've encountered before.

Maybe try remaking your SaveGame object from scratch and making sure a new copy exists on disk.

[hollow cove]

where would it be stored in saved folder?

[dry sleet]

SaveGames, I believe?

[hollow cove]

yeah its there

the logic

this is printing

[brisk rain]

yo guys, how do i make it so it restarts the level whenever the character falls into the void?

[dry sleet]

Easiest way I can think of is to a) Teleport the player back to spawn, or b) Open the level again.

Depends if you want it to be fully from scratch or persist some of the level state.

[brisk rain]

yeah i wanna open the level again, how do i do that...

[dry sleet]

[upper badger]

I have a character BP and a gun BP - I want to keep all the shooting logic of the weapon in the gun BP. The gun BP is a child actor component of the character BP. When I put the IA shoot event in my character BP, it works fine. But when I move it to the gun BP it does nothing. I tried to create a "shoot" function in the gun BP so that I can call that in the character BP, but it's not showing up. What am I missing?

[dry sleet]

I would advice against using the Child Actor Component for starters. That is the general recommendation.

For ex-Unity developers it often feels like a "prefab" substitute, but it's janky and causes issues.

The reason being that it's not really a blueprint in a blueprint -- rather a component that spawns an actor and attaches it at some point.

It is much better to spawn the actor yourself using the Spawn Actor from Class node and attach it any way you want.

The reason the "shoot" function doesn't show up may be related -- when you get a reference to the Child Actor Component, you're not actually referencing the Actor it has spawned -- only the component itself.

You need to use some node to actually retrieve the Child Actor. I believe it's called something like GetChildActor or the likes -- it's been a while, I don't use it anymore.

[lunar sleet]

Yeah it’s get child actor but like you said, CAC is caca

Also the FPS template shows you how to use a regular actor component for a gun

[fickle quartz]

It seems I needed to set both the capsule collider and the mesh of the human AI to "Can Step Up On," even though I'd told the capsule collider to ignore pawns so you can fly onto the mesh. Thanks for the help!

[upper badger]

goddammit i didnt think to check there. thanks!

[hollow cove]

does loading from a slot crash if you do it within a function?

did it directly from the widget and it works

[dry sleet]

It certainly shouldn't!

Where did you do it previously?

[hollow cove]

ah ive figured it out

ive got a while loop thats bugging out

[dry sleet]

Ah right, yes, that sounds about right

Nice!

[empty marten]

Hey peeps,
Need help with something that I honestly can't explain at this point. I have a cube (test object) which has a tag of 1 on it (for testing) and has collision of block all. I have a pawn camera actor that I posses (unposses thirdpersoncharacter and then posses camera). Whenever the line trace from the camera hits the cube, even though it has the tag of 1, it doesn't set the text in my UMG and I've no idea why. Might it have something to do with the fact that it is casting to the UMG on an event tick through the line tract code and its just crapping out or am I missing something here?

Something I've just noticed as well, if I leave it for a minute or so it does set the text but there is a delay for some reason even though there is no delay node. It takes a few minutes but will then set the text. WTH is this code doing XD

[lunar sleet]

No idea, you didn’t show all the relevant code, you’re talking about “casting to UMG” and I don’t see any casts

[empty marten]

Sorry. Should have set "get all widgets of class" instead. 2nd image.

[lunar sleet]

Use breakpoints and step through the code to see exactly what’s happening

[empty marten]

did that. everything gets executed and it still doesn't set

i just re-did it incase and noticed that it gets stuck between 2 nodes

it switchs back and fourth i'm assuming cos its on event tick

so its not actually getting a chance to proceed forward now

[dry sleet]

Stuck between which nodes?

Unless you're doing async logic, which I don't think you are, there's no possibility that the code "doesn't have time" to finish.

Code and Blueprint graphs always finish.

[empty marten]

between Character Details execution node from the get all widgets of class and the character details custom event.

So last node in 2nd image and 1st node in 3rd image.

[dry sleet]

Then that would seem to imply the Get Widgets of Class node returns nothing.

Are you sure the array isn't empty?

[empty marten]

Would a cast to the UMG widget be more suitable in this situation over the get all widgets node?

[dry sleet]

Honestly I don't know where this code is running.

[empty marten]

Image 2 is a pawn actor. Image 3 is a UMG Widget

[dry sleet]

Then you should definitely retain the UMG widget you created previously (as a variable), rather than attempt to fetch it with that node.

[empty marten]

OK. I will try that then and see if I get a different result.

No difference.

This is so weird

[dry sleet]

Is this the only place you're updating the widget text?

Or have you used Binds or something?

There's a SetText function.

[empty marten]

Used binds

As the text for them is retrieved from a data table

[dry sleet]

Better to use SetText in this case, because binds update every tick, which is unnecessary if you have a good entry point (like your CharacterDetails event), and don't need it to update every frame.

Might not be the issue, though.

Again, step through your code and see if everything is valid.

Add some DebugPrints to see if the various parts are even reached.

Anything in the Output log?

[empty marten]

Nothing in Output log.

I'll keep playing and hope for the best

I might just create a new widget with just a simple text in it and just see if that pings. If not then i'll try some other things

[dry sleet]

Good luck!

[empty marten]

Might it have something to do with text being text and the variables I'm setting being strings?

[dry sleet]

Probably not, but I would replace the mysterious Bind functions with intuitive SetText calls if I were you.

Then I would also suggest having those character details be text instead of strings, because pretty much all user-facing text should be Text.

[quick imp]

Has anyone set an animation blueprint in a datatable and then pull it from that datatable and set it to the skeletal mesh in a character blueprint?

[empty marten]

I will make the changes then

[oak wind]

Hey guys. I’m trying to get the enemy to chase me when it sees me, and keep roaming around when I hide from it’s sight and it stops seeing me. However, it’ll only do one or the other. If I leave the End Overlap(LineOfSight) connected and the BeginOverlap (LineOfSight) connected, it’ll completely ignore me even if I’m on it’s line of sight, however it DOES detect me as the “I see it” print string shows up, it just doesn’t chase me. If I break the pin link from the End Overlap, it detects me and chases me, but it won’t ever stop chasing me even if I’m out of its vision (line of sight). The behaviour tree also won’t switch branches. I’m still very new to unreal and I have no clue of how to fix it, I’m kind of going insane! if anyone knows what’s going on and how to solve it please lmk.

[trim matrix]

guys how can i make a simple zoom effect on my camera changing the fov?

a gradual transition

[empty marten]

I made the following changes as suggested (stopped for dinner so took a while XD) and now I get this in the log so there is defo something wrong when it tries to get the info from the data table lol

[candid gorge]

What do I use for this since my begin play is already being used for something else?

[empty marten]

Heard of the sequence node?

Very useful

[candid gorge]

I haven't

[empty marten]

It's useful for splitting off events from 1 event but make sure you put things in the right order when using it.

[dry sleet]

Hold S and click

(in the graph)

[candid gorge]

So it splits it in 2?

[empty marten]

and more

If you hit add pin, it will add another execution pin

[candid gorge]

Thank you

[random pulsar]

how to set up invulnerability?

when character is hit

this is from my character

and this from enemy

[obtuse mulch]

just dont apply damage 😄

or new bool on character

[random pulsar]

i tried the bool but how do i change the flow

[obtuse mulch]

what flow

[random pulsar]

where do i set the bool to false and where to true?

[obtuse mulch]

do the invulnerability bool

if invulnerable false set HP

if true dont set HP

[random pulsar]

yeah but where do i set them manually?

[obtuse mulch]

how does your character get invulnerability?

its a skill or smth?

you set it when casting a skill

on button press or custom event

[random pulsar]

he doesnt have anything,thats why im asking

[obtuse mulch]

so first you have to make a way for it

or just do it on button press or smth

its up to you

[random pulsar]

ok,i have an idea to,disable enemy collision and after x time to enable it

i changed my mind,i will disable player collision

holy shit ,character fell throw the floor😂

[royal vale]

How can you set a variable of a child actor in a BP?

For my example I have a blueprint called "BP_floor" and that bp has a child actor component called "LavaFloor" , I want to set the variable called "LavaDamage" .
I want to set a variable that resides on the child actor component in game via nodes , but unsure how to access that setter.

cant find the right thing to plug into the target of the set node

when i try to plug in the child component i get this incompatibility message

[random pulsar]

omg,its so simle ,just disable and enable collision channel

thats it

lmao

no need of branches

[trim matrix]

guys is there a way to make the mouse cursor exit the screen?

or like make it move infinitely?

[random pulsar]

set show mouse cursor disable

[trim matrix]

not really what i need, have you ever seen the amnesia game item system?

where you can rotate the item in front of you

[random pulsar]

when you need the cursor
set game mode to ui or game and ui and show the cursor
when you dont need it
set game only and hide the cursor

[trim matrix]

my cursor is always hidden

the main problem is that it stops spinning when the cursor reaches the limit of the screen

[royal vale]

solution

[random pulsar]

well i am not that good to help you,hope others will help

[trim matrix]

no problem, thanks anyway

[hidden timber]

Why in the world is this not working? Works fine on every other blueprint

[dry sleet]

That's the solution! But I wonder if you won't encounter issues if you continue working with Child Actor Components!

Unfortunately it's not very good

A lot of people end up using it to replicate Unity's prefabs, but Unreal's CAC is a very janky thing.

The reason is that it's not really a matter of nested blueprints -- a CAC is a special component that spawns a Actor and attaches it automatically.

[leaden sun]

I'm aware of an actively using GameInstance and GameMode, but is there a way to create effectively "sub game instances" that can house grouped bits of logic? E.g. a specific game instance manager for certain bits of logic, rather than dumping it all into one massive game instance?

I could throw XManager actors into each level, but its just a bit annoying to have to do that

[dry sleet]

But because you don't handle the spawning yourself you're at the engine's mercy for a lot of things. The spawning template thingy is very strange, for instance -- and if you want a SaveGame system further down the line, it's very common to run into issues with your CAC:s (because they're not persistent).

[dry sleet]

https://docs.unrealengine.com/5.3/en-US/programming-subsystems-in-unreal-engine/

Subsystems, I suppose.

I've never created one myself (used a fair few though) -- and it's C++ only.

[iron bone]

how can i move a pawn from within my level blueprint? I've tried making a reference to the pawn but it isn't responding

[leaden sun]

Yeah I was worried it'd be C++ only :/ - any other alternatives you can think of?

I was thinking of making actors and just spawning them at runtime through my gameinstance

[dry sleet]

Using the GameInstance and not worrying about logic grouping!

Create some categories and be merry!

[leaden sun]

fair enough, I will throw my worries aside!

you've given me the confidence I needed to thrive haha

[dry sleet]

Haha I'm the same way, I love the idea of some managers -- but I surrendered to convenience.

[leaden sun]

Yeah. I guess one thing that's nice about distinct managers is that I could have some little helper BPs that say getFunkyManager, or getCheekyManager, and then only be able to call specific bits of logic on each

this way anything is possible, but alas categories is probs fine

[dark drum]

You can use actor components and place them on the game instance or game state.

[dry sleet]

The game instance can't have components, can it?

[leaden sun]

How?

[dry sleet]

At least not via the BP editor -- maybe again C++?

[leaden sun]

The component route was my first idea but I could not work out how to (assumed it wasn't possible)

[dark drum]

When you create a new BP select actor component. Then just add it as a component as you would in any other BP.

Edit: it might just be on the game state though.

[dry sleet]

But I don't believe the GI editor has the components field?

[leaden sun]

I'm talking about the game instance here though, which isn't a typical actor/BP which lets you add components

[twilit inlet]

no matter to what value i set the move speed variable, my newly created cube on this blueprint moves at the same speed, can someone tell me why?

[random pulsar]

what nodes do i need to connect in play and reverse?i want this lerp to repeat in loop

i thought about tick and 2 custom nodes

but i think thats not it

[dark drum]

You can probably get away with using the game state which you can add an AC too.

[dry sleet]

Just a little extra unsolicited advice! It looks like you're maybe creating a whole boss arena in one Blueprint? In a Unity prefab that'd be a good approach but Unreal's Blueprints are meant for smaller (single-purpose) things. Many interconnected systems like that are better suited to place in the level directly and reference together instead. If you want to be able to duplicate the Arena (drag 'n' drop style) you could look into the new Level Instances system, it's a little closer to Unity prefabs IMO, although still has some annoying limitations.

[leaden sun]

is game state persistent between levels, like GI?

[dark drum]

No, its created when the map loads.

[dry sleet]

go on, give into using the game instance

[leaden sun]

lmao

I think it's a done deal

[leaden sun]

not enjoying the scrolling though 😂

[random pulsar]

this does not work

[dark drum]

What are you needing to persist between levels that can't just be stored in a save game object?

[dry sleet]

haha ouch but you can at least collapse the categories!

[random pulsar]

@dark drum how can i play this timeline constantly?what play and reverse events i need?

[dry sleet]

I don't see any reason that shouldn't work.

[random pulsar]

cuz i used to make timelines with triggers but now i dont need triggers

[dark drum]

Make the curve so it goes from 0 to 1 and back to 0 again in the timeline itself so there's no need to reverse and then just set it to loop inside the timeline

[random pulsar]

also no events will be used,oh i remember this detail

thanks

[random pulsar]

it does not loop

[dark drum]

Tick the diamond with the line next to it and call play on the timeline.

[hidden timber]

Nothing seems to want to fit in task owner, so I'm really confused right now

[random pulsar]

also no

[flint blade]

Hi all -I have a simple one that I'm sure I am making way harder than it needs to be. I have a float value (call it health) that is being set by a for loop every second. So at second 1 , Health = 0.1, and second 2, Health =0.2 and so on. I have this linked to a widget, with a progress bar displaying the float value. How would I smooth out the progress bar, so even though I am only calculating the float value every second, it is being displaying every tick, with the values interpolating smoothly over the duration. I assume It has something to do with every tick @ 30 fps will mean need to update the value 30 times per second, or there is a function that will achieve this?

[dark drum]

Use the finterp node to set the percent on the progress bar.

[flint blade]

Thanks for the quick response. This is what I was trying, but clearly I am doing something wrong... 😄

[dark drum]

It looks ok but if the target does change, you might need to use the constant version for the finterp.

[faint pasture]

What are these managers?

I'd make components on GameState probably

[trim matrix]

is there any way to change post processing of a camera with blueprints?

like depth of field

[leaden sun]

Just bits n bobs. Sound manager, manager for specific groupings of stuff that I have in my game, etc.

[faint pasture]

Yeah a component on GameState or GameMode is what I'd do if Subsystems are out of the question

[flint blade]

Well... now you put it like that, thanks 😄

[faint pasture]

and put the speed to something non zero

the speed is in percent per second

er

it would be if this was finterptoconstant

the speed will be faster the further away it is with FInterpTo

FInterpTo = Constant Time to get there, goes faster the further away it is.
FInterpToConstant = Constant SPEED

[flint blade]

Ok - this make much more sense. I thought it was "how many ticks to get from A to B"

[faint pasture]

It's how many ticks to get halfway from A to B or something like that. If A and B are further apart, it'll take the same amount of time

the constant version will change Current towards Target at up to Speed

[flint blade]

Awesome - thanks for clarifying

[faint pasture]

FInterpTo = Ease In
FInterpToConstant = Linear

[stoic nimbus]

Hello, I needed help with this blueprint related to player stats. I was following the tutorial linked below and he started using a Dynamic Material for his HUD images, like the health, thirst, and hunger. But I was just using a background and filler image for my HUD. So I got to the part of 31:42 / 38:07 in the video, but I was not sure what to connect (me not having a dynamic material). What should I do here so that it updates? He puts Update with Value, but I don't have access to that node because I'm not using a dynamic material. Any ideas? If it's a complex process, is there a tutorial out there that allows me to create stats, via a component?
https://youtu.be/M6feAf2Qh1o

[dull glade]

Hey guys! I've been looking around for a while for making a randomly generated map, with premade meshes for the rooms (to make the generation more strict), but the tutorial landscape for this is non existing it feels like, any advice?

[true valve]

Anyone knows about smart objects?

[fluid crescent]

guys i moved playerstart around and now this happens, what do i do

[flint blade]

Would anyone know how to create a dynamic widget that looks something similar to this? Intent would be to input from a blueprint a start date and end date and the widget would automatically size, show each month etc

[stoic nimbus]

For stats what better; To put stats in functions in the characters BP, or to put them in a component?

[thin panther]

It depends

not all stats belong in either

[stoic nimbus]

What if its just for stamina, hunger, thirst, and health?

[thin panther]

I probably wouldn't bother making those components unless other things need those

If this was for something like a survival rpg, i would be handling all of those through GAS

otherwise on the character

[stoic nimbus]

What if its for a survival type game?

[thin panther]

there's a difference between a general game with survival mechanics, and a survival rpg

the latter being incredibly more complex, and something you'd likely want to use GAS for anyway

[stoic nimbus]

Whats GAS if you don't mind me asking?

[thin panther]

Gameplay Ability System

it's the engine's framework for using abilities, which often affect things like health and whatnot

as to whether you use it or not, it depends on how in depth you want to go with things, and whether you plan on shipping the game

[stoic nimbus]

In what scenarios would I use functions for stats and components for stats? (Sry im kinda new with the stats stuff in UE)

[thin panther]

Components are really for when you want reusable behaviour.

If you weren't using GAS, but has other things using health, you could slap a health component on whatever, and have it handle health related things for you without needing to remake it. having them tied to the thing itself as just variables is more for just occasions where you don't need to repeat anything. I.e. I know for me, only the character would have thirst, so I wouldn't bother doing anything component based

[stoic nimbus]

Just to clarify the part toward the end, you mean if I only want those stats to effect one thing I should use functions?

[thin panther]

You'd be using functions in any case. The important thing here is making it modular or not.

If it's only affecting one thing, just tie it directly to the class. If it's going to be used in many places, you may want to consider extracting it into something like a component

[stoic nimbus]

What would you recommend for a beginner with stats and survival aspects (stamina, hunger, thirst, health)?

[thin panther]

Either are fairly simple and good to learn..

Id start really basic and play with them on the character while you're learning the ropes. but for a game you want to release and have a chance at doing well, look into better design practices

You won't be making anything complex at this stage, so go with the simplest route of just making each of them variables, and adding the functionality in the character

[stoic nimbus]

Awesome, thank you! Also does adding lots of functions within a character affect performance?

[thin panther]

Not really, there's far easier performance gains than that.

Always make sure to profile your game though. That will let you identify the main problems slowing you down.

(Also remember if a function gets too slow in your game and you've done as much as you can to optimise it in bp land, c++ is much much faster)

The main issue with adding tons of functions is readability

It can be quite hard to alter things and find what you want

[stoic nimbus]

You think in UE5.4 they'll fix this? Or add better performance?

[thin panther]

Thats not an engine issue, it's an issue with the way you've made things

[stoic nimbus]

Ohhhh, I see!

[fluid crescent]

yo when op fixes his problem can yall adress me then for a sec

[stoic nimbus]

Thank you for your help!

[thin panther]

Imagine it like covering your desk with 10,000 pieces of paper. It wouldn't be the desk's fault you can't find the piece you're looking for :P

[stoic nimbus]

XD Thats a good way to put it!

Do you recommend any good ways to learn BPs in UE5?

[thin panther]

The pins in #ue5-general, after that just keep making things

[stoic nimbus]

Awesome, thank you!!

[thin panther]

(and avoid bp structs)

You'll know what that means when you come across it

[fluid crescent]

hey can you help a extremelly noob fellow for a sec

[thin panther]

Only thing I can suggest is delete and re-add it.

There is little reason that should be doing that, and it might be a case of a somewhat rare engine bug

Alternatively ensure basic things like a valid game mode setup, the player start is in a good place etc.

[stoic nimbus]

Ok, thank you so much for your help!

[thin panther]

Failing that, give the engine a verify

[fluid crescent]

ok thx a lot imma try that

[thin panther]

No problem! Good luck on your journey

[stoic nimbus]

Thank you!

[fluid crescent]

yeah this is embarassing but may i ask how you re-add stuff??

[rose helm]

This currently works with pickup interaction, how would I add physics though

Simulated physics on the world model didn't work nor does it really make sense since it'd probably just fall out of the origin of Pistol_Pickup anyway

Unless blueprints themselves actually have no transform or any locational data which seems to be the case and I feel extremely stupid for not thinking about it until now

But my point still stands, "Invalid Simulate Options: Body (Pistol_Pickup_C_0.ItemMesh PistolCombined) is set to simulate physics but Collision Enabled is incompatible"

[visual crest]

I have a pretty advanced question. Is it possible to live update the numbers this blueprint displays? https://blueprintue.com/blueprint/iszyq3h7/ I want it to add any numbers added together as long as the particle system is still active. If I was using plain text such a thing be easy but this setup is a bit beyond me, tho I really love the looks of it compared to normal text.

[lyric basin]

What do you mean, re-add stuff?

Did you delete something and want to undo that?

[lyric basin]

You're talking about a rolling total, like damage over time but continuously updated as damage is applied, yes?

[visual crest]

like you take damage right on top of each other while particle is still active. Instead of spawning a whole new system I want to update the current one with the new total of the old and new added together

[visual crest]

Yes basicly

[wanton prism]

Could someone help me with my objective system i followed a few tutorials and then tried to have a crack at it myself its not updating it?

[lyric basin]

Is there any more to it? Like, what feeds into this? It's taking values from somewhere. I have an idea but not sure

[lyric basin]

What's it's doing vs what you expect it to do?

[visual crest]

This is my current setup. As you can see the numbers overlap two 12s right on top of eachother

[visual crest]

Just the numbers

[lyric basin]

You'd need to manipulate how it's called. Cause each call is gonna display new numbers. Perhaps have the total collected and then fed into the function after a half second delay.

[lyric basin]

Can you record a short clip showing me how they spawn?

I'm on Mobile so can't recreate it right now

[visual crest]

Yea thats what I thought I'd have to do

Was hoping to update it live because I think that be cooler

[lyric basin]

Definitely would be yeah

I'm thinking

Is there a destroy system node?

[wanton prism]

its not updatin the text

[visual crest]

Naw I have it auto destroy

[lyric basin]

What is that little note on the cast node?

[lyric basin]

Right, but what if you had it destroy on receiving new input and the new input be the new total

[wanton prism]

its just saying im already casting to the object

[lyric basin]

Well, try removing it if it's a redundant node

[visual crest]

Then it be the same as what I have already

[lyric basin]

Okay I'll get to me editor

See if I can recreate it

[wanton prism]

Didnt work and got this error

[visual crest]

do you need the numbers and Niagra systems?

[lyric basin]

perhaps

[lyric basin]

most of the time, when I see issues where on screen text or prompts arent updating as expected, it has to do with the desired value either not being captured/stored/called correctly or not being passed at all.

[wanton prism]

any suggestions?

[lyric basin]

what you can do troubleshoot this is either recreate the BP from the tut you followed and look at whats different or start using print nodes to see where it breaks

personally, I have multiple monitors, so I just put the editor on one screen and put the player on another and watch the nodes fire in real time while I play

[wanton prism]

i think my puzzel isnt calling the update correctly

[lyric basin]

try what I suggested if you have two screens. otherwise just put the windows side by side on one screen

[lyric basin]

when the text is supposed to update, you can watch the nodes to see if they are being called and firing correctly at all

[lyric basin]

thanks

why a zip?

[visual crest]

👍

Smaller?

[lyric basin]

wait did you upload the project?

[visual crest]

naw just the numbers and nig effects

the project is like 15g lol

[lyric basin]

eh not really sure I can use this but let me see. I dont have a dummy project. one sec

[leaden plaza]

would there be a way to connect an actor with a connection point to another actors connection point after the game starts?

or what would be the best way to do this

[wanton prism]

For somereason this works?

[visual crest]

I understand if you have a fast internet 😛 https://github.com/LordMaddog/DarkSouls-Like_CombatSystem-UE5

[lyric basin]

oh ive got gig speeds. fast aint an issue lol

im recreating it

[visual crest]

ok

[lyric basin]

straight forward and simple

[lyric basin]

sockets?

[leaden plaza]

alright

[wanton prism]

should i just add that to the puzzels code

[ionic holly]

hey, I'm messing around with the starter content. I deleted the C++ parent class of a BP, created a new C++ class, and decided to reparent it, but the BP with the original class can't find my new C++ class

the weirdest thing is that, if I create a new BP class, I can see my C++ class just fine

(name of the new C++ class is FirstPersonController)

[lyric basin]

yes. Once you have the system working and functional, then you can expand on it.

[ionic holly]

I've also noticed that list is a different size (~200 items on my new BP, and ~400 items on the old BP that can't find the new C++ class)

[lyric basin]

careful doing this. you can brick your project. for some reason, I get the feeling you copied code you found online, am I right?

[ionic holly]

I didn't copy code online. I'm copying code from the starter project if that makes sense (I'm just re-writing to see what the functions are)

[lyric basin]

okay, yeah makes sense. there is probably something thats tying them together. why do you wanna use the default bp with your new c class? if you can create a new bp, then why not just use that?

[ionic holly]

yeah, I can always make a new BP. I wanted to see how easy it was to recover from stuff like this

[lyric basin]

to me, it isnt. rooting around with default classes and stuff, esp the c++ stuff, I usually leave alone.

Or at least, create children of it to play around with and leave the default base stuff alone.

that way if I mess up, i just create another child class

[wanton prism]

It gets right there at the red then it stops working?

[lyric basin]

something to do with the cast then.

[lyric basin]

where does this code live? is it inside the FirstPerson BP? or somewhere else?

[wanton prism]

yes but the thing that calls it is in a seperate thing

[ionic holly]

got it, so it's generally not easy to recover.

I'll commit my changes before messing with it next time so I can revert if things go bad

[lyric basin]

lol yup thats the safest thing to do. good thing about the starter content is you can just reimport it into the project without messing much up.

[lyric basin]

alright, i got it working like you have it. slick system. so the numbers just spawn to the right of the original numbers. lemme try getting it to update

[visual crest]

Cool

[lyric basin]

alright, I got a solution, but I dont know if youll like it

you basically need to split your niagara effect into two systems. one to spawn the number and the other to do the floaty thingy

then plug them both into a sequence node.

[visual crest]

0o

[lyric basin]

the first fires and puts the number on screen, totalling up and all that jazz. after a set delay (pause between attack), the system destroys and the second node fires making it spawn the numbers and floating them away

[visual crest]

how good does it look?

[lyric basin]

if you time it right, you can make it seamless

oh i didnt make it lol thats just what I came up with. its based on how the niagara system is set up. it handles spawning the numbers and making them float. I cant interupt it and change the number since it all happens together.

at least, not that I can see how to.

sorry, ui and effects arent my thing really.

Im more about mechanics and getting events to trigger and stuff.

but i gave it a crack

[visual crest]

Ah I see you use text then convert to efects

[lyric basin]

sure, just spawn the numbers like you do right now, but as soon as its destroyed, spawn the same numbers with the floaty effect

that way, you can have it show the total damage (rolling or static) first, and then it floats away, regardless of the number

and if the player attacks just after the delay lapses, its treated as a 'new' attack, adn a fresh cycle begins

[visual crest]

I see

[lyric basin]

thats how it works in my head

to me, splitting the effect into two should be okay since you got this far

[visual crest]

could you post the code to past bin?

[lyric basin]

um sure, I can try

I dont have it mocked up

lol just closed my editor

[visual crest]

lol

[lyric basin]

i need to put a number system into my game eventually, but I leave UI stuff for later. working on my map and design atm.

[visual crest]

I understand the principle of what your saying but it would likely take me two + hours to do lol

[lyric basin]

the effect or the code?

[visual crest]

the code

[wanton prism]

I went and made it a event in bp_firstperson still not working though?

[visual crest]

Well both

[lyric basin]

that means that nothing it being passed to the function when its called

[wanton prism]

How do i fix that?

[visual crest]

Put it before the destroy maybe

[wanton prism]

ok

[wanton prism]

but its not destroying the actor though?

still didnt work?

[visual crest]

What that event look like? and do a isvalid on the player before you pipe it in and put a print string on the false to see if your player is even valid to begin with

[visual crest]

Yea your reference to the player is not valid

[wanton prism]

how do i make it valid?

[visual crest]

how are you getting and setting it?

[wanton prism]

im getting mission widget and then getting player and then starting the event

[visual crest]

no how are you setting the player in the picture where you are destroying stuff

[wanton prism]

the destroying the actor isnt part of player bp thats part of a differnt blueprint il show you i remove the destroy

[visual crest]

that player reference is not valid. Also for future ref show as much code as possible if you are asking for help.

[wanton prism]

so should i just remake it?

[visual crest]

No that different blueprint you refer to that is calling the event can't call the event because the player variable you are using is not valid.

[wanton prism]

so how would i make it valid?

[trim matrix]

I am working on a project due in 48 hours and need to build a plugin interface for Unreal Engine. I don’t need the plugin to have any functionality, but ideally I would be able to use drop down menus, radio buttons, and sliders.
I understand that programming something built into the interface of Unreal is an endeavor that can’t be done in a few hours. But a better solution might be to use Unreal Menu Widgets, build the menu, then simply open it in a game level.
The problem is, I can’t get the menu to show in the viewport when everything is compiled correctly. Here’s a screenshot of my node graph (is that the right term?) and of the test menu.
I understand you probably think I know next to nothing, which is true, but any help is appreciated.

[visual crest]

Cast to the player and set it or pass the ref through to it when you spawn it then set it

[visual crest]

you see here I am setting my character/player

you have to get that reference and set it on any BP that is not your player if you want to use the player in that blueprint

[wanton prism]

?

[visual crest]

is the owner of that blue print the player? if not then you need to use get player node

[wanton prism]

ok

[wanton prism]

it works

thank you brother

[visual crest]

That node will work fine if you aren't using multiplayer but if you use multiplayer you will have to get an exact ref to the player you want

[wanton prism]

Yeah i havent taciled multiplayer yet

[topaz gazelle]

I made a variable with the type as an actor blueprint, I can't seem to edit its default value.

[unkempt warren]

It is best to start with multiplayer and not try to implement later or you will hate yourself. You can ask in #multiplayer chat they will all tell you if you make a game it is like 10 times worse to make it multiplayer then to make it from the start as multiplayer.

[wanton prism]

not in the project

this

i just meant i havent made a project with multiplayer

[unkempt warren]

Oh okay, I was just giving a heads up. So you don't screw yourself.

[wanton prism]

all good

[glossy kraken]

Im having an Issue, where I want to check if the mesh is on the Ground or not

and when the game starts its working perfectly. But as I apply Force to the mesh to move it, the endoverlap event still gets triggered, even tho its still on the ground

anyone knows whats up ?

[unkempt warren]

Isn't there a IsMovingOnGround function built into the character movement component? Does that not suit your needs for this type of thing?

[glossy kraken]

technically yes, but this aint no character

[unkempt warren]

Maybe run a linetrace from the feet of said actor for like 5 units and if it touches something then set Is Touching ground?

[upper badger]

I'm trying to study the FP template - it says that the BP_Weapon_Component is supposed to be used by the BP_FirstPersonCharacter and BP_Pickup_Rifle but I don't see it in the component list of either BPs...?

[glossy kraken]

line trace would be too thin for my taste, I want the Character to be able to jump even if hes a bit too far from the ledge

[lunar sleet]

So shape trace

[glossy kraken]

but why is begin and end overlapping not working tho ? 😄

[lunar sleet]

Are you spawning this guy inside the overlap zone?

[glossy kraken]

nope

hes is falling on it

[lunar sleet]

Then check your collision settings

On both ends

[glossy kraken]

thing is he IS colliding

but after a bit of movement hes not anymore

except for the place where he started falling

wait a sec

[lunar sleet]

BeginOverlap fires once

Not on tick

If you want to check he’s still overlapping getOverlappingActors on tick or on a timer, after begin overlap fires

[glossy kraken]

thats a good point !

imma try that one out thanks

Thanks, that does work !

but now im checking and setting every frame...

Best case for me would be to make this event based

and heres the issue that i was having with the event based system

it is kinda off, cause the end overlap gets triggered, even when moving on the platform and not ending the overlap

[dull glade]

Hey guys! I've been looking around for a while for making a randomly generated map, with premade meshes for the rooms (to make the generation more strict), but the tutorial landscape for this is non existing it feels like, any advice?

[true valve]

Can you play anim montage on AnimationShared Character?

[jolly hedge]

hi guys, where do you guys look for information about something you want to implement?? is there any specific good sites for this? for BP of course. Do you just search up on youtube or? Like say for example i want a BP_Character to jump. do i just search up on youtube or do you guys have other good websites?

[fiery swallow]

youtube

asking here is also a great way to learn things

[jolly hedge]

well where does youtubers get their info? do you get me?

[fiery swallow]

pretty much youtube and any discord/forums for unreal

[fiery swallow]

they got it from someone else who taught them. From what I can tell 95% of the tutorials you'll find online are written by someone who is still learning themselves. Expert programmers are most likely too busy to be making actually good tutorials. That includes Udemy courses.

But there are lots of documents posted by unreal as well as unreal programmers

https://docs.unrealengine.com/5.3/en-US/

This is where you'll find a lot of helpful unreal engine related documentation. Finally, many things that aren't documented on the website (and there a lot of things that aren't documented on the website) can be found in the actual c++ code of unreal engine

Epic games does a pretty good job of commenting on the code and systems built in unreal

After a while of practice, trial and error, etc. You just start to learn how to do things on your own.

[fiery swallow]

I'm not sure if you can have a randomly generated landscape. However it sounds like the term your looking for is "procedurally generated" levels. I'd recommend searching from there

[dull glade]

I have tried that, but someone on reddit said I should look up wave function collapse

[fiery swallow]

never heard of it, are you trying to procedurally generate a landscape, or the contents of the landscape?

like the tree's, where houses spawn, etc.

[dull glade]

not landscape, but more like a dungeon

[fiery swallow]

yeah, in that case, I would recommend a sort of tile system for randomness similar to the way dead by daylight does it

[fiery swallow]

You'd make a bunch of different standalone actors or something called a tile, and each tile could have it's own layout, as well as things that spawn inside of it. For example you could have one tile which contains, a chest, an enemy, and some dust particles, a different tile might contain something else... In the code you'd pull a random integer from stream to figure out which tile should spawn in the location you designated.

[dull glade]

do they know if they overlap and stuff etc? or is that something I'll have to blueprint in? I saw someone say they do, but not sure haha

[fiery swallow]

Does what know? Usually when making something procedurally generated there's an algorithm you create to ensure what is, and isn't possible, as well as what must be present

[dull glade]

yeah realised that it was a stupid question haha

[fiery swallow]

haha, it's up to you to create an algorithm with a strong set of rules to ensure things play out the way you'd expect

goodluck

[dull glade]

sounds scary

thanks haha 🙂

[fiery swallow]

It's a lot easier then it sounds I promise

just take it one step a time

[dull glade]

thats good to hear haha

[dry sleet]

Unreal has an experimental plugin for WFC just so you know!

Fully blueprint capable, too.

[dull glade]

oh!

neato

thanks for letting me know 😄

[dry sleet]

You can enable it from the plugins manager, and there's a demo scene as well to show the setup

np!

It's a little janky but overall pretty neat

[dull glade]

I'll try it when I get home, thanks again!

[dry sleet]

Good luck! If nothing else it's really fun to play around with :)

here's a little city I got out of it

I created buildings with CubeGrid and "taught" it how to assemble them.

The intriguing part here is that it managed to create the road forming a continuous loop around the city just from the simple constraint "a road must be connected to another road"

But the main downside with WFC is that it's not guaranteed to succeed and also is slow. It can fail and then you have to try again until it does succeed.

Might be good to create a large assortment of predefined chunks of map instead of trying to do it live!

ah, found a pic from somewhat later experiments

[silent drift]

I keep having quite "unreliable" hit events when being sucked into something. Has anyone else seen this? I have added a video to see if anyone can help.

[steady night]

is there a way to set how many "loops" before turning off or do i need to do my own logic ?

[distant hollow]

Own logic

[steady night]

ok

[distant hollow]

What is "Shield"?

[silent drift]

Just a static mesh to show the shield

And if the player gets sucked into it, I want to hurt them, but unless I actually forcefully run into the shield, they don't get hurt.

[distant hollow]

Yeah where is this "Shield" on? The ball?

[silent drift]

It just a normal BP Actor, that I have two static meshes on.

[distant hollow]

Ok I see what you mean now

[silent drift]

And do some logic, so the player get stucked towards it and when getting "into" the shield part it should hurt, and but if they shoot the ball they will destroy the shield (None of this is final art if that isn't obvious). 😄

[distant hollow]

The entire thing is the "shield"

[silent drift]

Yeah

With just two components, one that can take damage and destroy it, and one that should hurt the player.

[distant hollow]

It's probably in the calculation of what defines the "Hit" event

Unfortunately I'm not familiar with this

[silent drift]

Okay, but thanks for trying! And I wonder if I should use something else to define it...

[pulsar vigil]

Hey guys i have a classic spring arm + camera in my bp caracter to control the camera, and i would like to as in the viewport when i press the midlemousebutton make it that the camera detach from the spring arm and u can move the camera in 2D lik u no longuer orbit around the character but u can move in the 2D space with ur mouse movement any suggestion ?

i just asked chat gpt3.5 he gave me a good answer lmao thats insane

[dark drum]

You can have a bool to determine how your inputs are handled. When true, update the spring arm location to move it around. When false, snap back to the starting location.

[sharp solar]

does anyone know how to make a slow mechanic ive been at it for 2 days and cant figure it out in the slightest

[frosty heron]

what do you mean by slow mechanic?

[sharp solar]

like ive got this slime and ive put a trigger box around it and have been trying to make it so when the player enters this trigger area they will be slowed

but only for while they are in the area

[velvet inlet]

howdy! I'm learning to make editor utility widgets. The first goal: a slider that controls the time of day parameter for the UltraDynamicSky which is in the current level. I did the Designer part, but I dont get the concept of how I can access the UDS value. Something with casting I assume?

any help appreciated 🙂

[frosty heron]

You can trigger a modifier (a buff preferably) that lowers the player movement speed

[sharp solar]

how would i go about doing this ( Im still somewhat new to blueprints )

[frosty heron]

In simple term, you just want to reduce the Player movement speed. But how you are applying and removing the effect will depend on how you design your game.
If I'm in your shoes, I would use GamePlay effect from GameplayAbilitySystem

[sharp solar]

would i find these in the world blueprint or create one in the content browser

[frosty heron]

GameplayAbilitySystem is what Epic uses for Fortnite game

it's available as plugin but it's not blueprint only add-ons

Are you having problem incorporating the system or you are not able to set the player movement speed to start with?

[sharp solar]

is it on the marketplace? tho with setting the move speed ive tried using the one already in the base blueprint but it wouldnt let me bring the trigger box into that blueprint

[frosty heron]

Not marketplace, it's available as plugin in the engine by default. You will need some C++ to set it up tho

[frosty heron]

Simplest form

1. OnPlayerEnter Trigger Box -> Get CharacterMovement Component -> Set MaxWalkspeed to X

2. OnPlayerLeave Trigger Box -> Get Character Movement Component -> Set MaxWalkSpeed to NormalWalkingSpeed

[sharp solar]

this is what ive been attempting but i cant seem to get the trigger box and player move speed into the same blueprint

[frosty heron]

You will need to get reference to the character in your Trigger Box blueprint

On Component Overlap or End Overlap have a REFERENCE to the actor that overlaps with the trigger box

Cast it to your PlayerCharacter and then you can access the movement component from there

[sharp solar]

like these ones?

[frosty heron]

@sharp solar freebie

if you want to make sure only your player character get it's movement speed modified, then cast it to your player blueprint instead of character

[sharp solar]

ah okay thank you so much ill give it a try now

[sharp solar]

where would you find the set max walk speed im struggling to find it

[frosty heron]

MaxWalkSpeed is a variable in the CharacterMovementComponent

[sharp solar]

ive got these

[frosty heron]

from other Actor -> Cast it to your Player BP- > From there you can get it's character movement component

Drag from the cast to get the class charactermovementcomponent

[sharp solar]

if i drag it out i can only set it the get is only one box

[frosty heron]

not sure what you mean by that

[sharp solar]

these are the only things i have

[frosty heron]

If you create those variable then you are not doing it right

you want the character movement component FROM your Character Class

You should learn references and casting before going further to do any gameplay stuff

1. From Other Actor -> Drag and Type Cast (Find Your Player Blueprint Class)

2. From the cast return value, drag from the blueprint and type Get CharacterMovement component

the rest is this #blueprint message

[winter pebble]

What's the best way to rotate something if I don't want it to "snap" to a given rotation, but move to a target rotation at a fixed rate over a set period of time?

[frosty heron]

interpolate to the target rotation

[winter pebble]

Sweet, thank you!

[thin cradle]

hey, is it possible to make blueprint save the content of a variable in editor even if it's not public? I have blueprints that in editor create other actors and keep a reference to them to avoid recreating them, but they only keep the reference if I set it instance editable (which I don't want to since it shouldn't show up in the details panel)

[haughty latch]

Has anyone ever tried loading a JSON file from Blueprints? I tried using both of these nodes and the result is empty. When investigating the value of the Success boolean output, the result is False. I wish to mention that the JSON is 100% correct because: a) it was exported from a Data Table from UE and b) importing the same JSON back into the Data Table via the editor interface works perfectly, therefore I can't understand why these nodes are failing to load it...

[versed sun]

make sure the path is correct

[distant hollow]

Any particular reasons for not wanting them to show up in the Editor?

[thin cradle]

they're being modified internally by the blueprint & editing them would break the blueprint's behaviour

[fiery swallow]

it's not really possible to do that

[thin cradle]

I ended up figuring out how to do it actually

[distant hollow]

You are sharing the project with someone else?

[thin cradle]

left instance editable enabled but also enabled advanced display

yes

[fiery swallow]

you figured out how to save actors in the editor on the next startup?

[thin cradle]

the variables weren't just being cleared when closing the editor btw they were being cleared every time the construction script reran

now it's fine

nvm the variables are still visible, at least they're in a subcategory

[distant hollow]

The closest thing I can think of is like maybe use a proxy

[pulsar vigil]

ty ❤️

[distant hollow]

Like set another public variable to its value and save that variable instead? iono

[thin cradle]

not sure what you mean, that public variable would have to be visible too

[distant hollow]

Yep, but you can probably communicate with the team to not touch anything on that blueprint or something

Wasn’t InstanceEditable and Public two separate settings?

[haughty latch]

it is, that's why I said I managed to import it in a Data Table via the Editor, using the exact same path, but the BP nodes don't want to do it for some reason...

[edgy elbow]

does anyone know how to get this to work? I want to assign each level a set value of an number, inegter prob, and then when in a certain radius of the sphere collision of the pawn it would play the music of the value the level has assigned (for example Fog Forest = value 0) essentually im trying to get battle music to play when in a certain distance near the enemy and have whatever battle music plays diferentiate depending on the level. Can someone please help lol im so close to figuring it out but im stuck

[empty marten]

Hey peeps,
I created a pawn actor called BP_Camera and its intent is to act as a security camera. You possess it, look around and then possess the main character again. I got the camera movement and all that sorted but for some reason it is starting possessed and initiating the following code even though I'm not possessing it. Am I using the wrong code here or missing a tick box somewhere?

[sand yacht]

hi, is there a way to render only one actor? I'm trying to make an in world jumpscare and want to have the monster do it's animation with a black background

but i dont want to use a video to keep the lighting the same

[wintry meteor]

hi, do anyone know any tutorial or documentation that explain on how to make trivia or quiz question game but through 3d widget not by HUD? i do really need it for my final year project

https://www.youtube.com/watch?v=rHo-DaooOvs&list=RDCMUClb6Jh9EBV7a_Nm52Ipll_Q&start_radio=1&rv=rHo-DaooOvs&t=15

or do anyone know how to implement this into actor? i tried manually change from HUD to Actor BP but seems function not work well.. but if through HUD its work well

[brisk rain]

Hey! I was just wondering how I can call a function from a player controller blueprint to a widget blueprint.

[late cosmos]

hello, how can i do an ai to stop moving when i see it? like scp173 or the colihead from lethal company, they told me to use the:Was Component Recently Rendered but i don't know where to start

[winter pebble]

I'm attempting to create a platform that periodically rotates towards a random rotation (within a given range). This is the code I'm using to achieve that and it works almost exactly how I want it to but the rotating movement is really choppy, and the speed changes depending on if I'm simulating, playing in the editor, or playing as a standalone game. Particularly interested in solving the choppy movement.

[verbal cloud]

hello. i just have a question if someone could please answer. if you create a variable array that's an object reference to e.g. a pawn blueprint, is the pawn it's referencing automatically added to the array as the first entry?

[dawn gazelle]

You need a reference to the widget in order to call a function on it from your player controller. You get the reference in the return value when you use the "Create Widget" node.

[brisk rain]

I meant ThirdPersonCharacter instead of controller mb

[dawn gazelle]

No different. You need a reference to that widget in your player character if you want to a call a function on the widget from it.
Generally speaking, you're better off not having your game logic call into your UI. Your UI can be separate and just read from the actors it cares about, but this takes a bit of thought into how your widgets are associated to anything in the game. So your widget then would somehow need a reference to the character instead, and could bind to event dispatchers that you create in your character.

Check the pins of this channel and look at the "Blueprint Communications" video near the bottom - it's a long one but it outlines how to get references and how you can communicate between different objects in unreal.

[dawn gazelle]

You're sort of going backwards - the "Current" value should be getting updated every frame, not the "Target".
Not sure if that'll fix the choppiness.... Also a bit odd that you would use a branch with == 10 in there as that surely would almost never hit due to how floating point math works.

[late cosmos]

.

[winter pebble]

That fixed all of my issues, thank you so much. I can't believe I made such a stupid mistake 🤦‍♂️ 😅

[dawn gazelle]

No. When you are creating a variable of any "object" type, then what you're doing is creating an empty bucket that can contain references to multiple objects of that particular type. If you're referencing assets, those can be added to the array in the editor, but anything that needs to be spawned, like actors, need to be added during runtime.

[verbal cloud]

thank you

[dawn gazelle]

Very simplified, and probably not your end goal...
On your SCP actor's Event Tick > Was Recently Rendered (plugged into a branch) [true] > halt all movement (set a bool)
Movement Logic > Halt All Movement [false] > Proceed with movement code

[late cosmos]

thank you

[kind estuary]

I have this camera that is placed in the world.
And i make it the player camera by using this node Set View Target With Blend.
What if i have more players? Will this still work?

It seems it wont work because its Get Player Controller 0

[dawn gazelle]

If you have more than one player, whether in online multiplayer or local multiplayer, this wouldn't be the way. Online multiplayer you almost never want to use the Player Index getters as there's no reliable way to know which player is which.

If these camera actors are replicated, then you may want to consider changing them into pawns, and having the player controller possess them.

[kind estuary]

so make the camera inside the player pawn itself?

but then thats hard to move the camera

need to move the pawn itself

oh well

[dawn gazelle]

The HUD works pretty much just like any other actor, and the only potential difference I can think of is how you call to reference it - if you wanted to use an actor instead of HUD for example, you lose the easy "Get HUD" function, and that means you have to use something else to get the reference to your actor, like "Get Actor of Class".

[dawn gazelle]

If you're making an RTS, usually your units are all AI controlled. The camera is your pawn instead.

[kind estuary]

exactly

so in multiplayer as you said get player controller 0 is not good

so we do by ID?

[dawn gazelle]

No, there's no need for IDs. Your GameMode will spawn the default pawn and possess it with the player controller joining the game.

So in your gamemode if you set your pawn to your camera, and have your camera pawn replicated, it should work.

[mighty ravine]

Hi all.
I’m trying to find a way to detect the rate of change with a thumbstick/joystick, similar to unreals built in GetInputMouseDelta.

I’ve tried a method that came really close to working, but it produced unreliable results.

1. I created a Vector2D out of the joystick axis’s.
2. I got the Length of the new Vector2D.
3. Set the Length to a variable(CurrentJS)
4. Used a Delay node
5. After Delaying, calculate the same Vector2D Length again, and then Subtract it from CurrentJS.

I DO get a result sometimes, but only if I set my Delay value to something between .19 and .1

Even then, it’s not a true reflection of the rate of change, it’s just a subtraction of position values.

Is there some kind of math I could look into? Am I going to have to brush up on my Calculus to solve this?? Am I just missing some critical node that would make this easier?
(I have done an embarrassing amount of web searching trying to find a solution to this lmao)

[kind estuary]

got it. thanks @dawn gazelle

[celest pilot]

I need a little push in the back, I've done vehicles before but I'm stuck on an idea.

I want to make a mech that is not a Pawn/Character but a "Vehicle/Actor" so not using the Character Movement because of some reasons but I have no idea how I'd make it move forward/backwards/sideways (input only, rest I can figure out)

[late cosmos]

i can't find halt all moment, @dawn gazelle sorry for bother you, im making this right? (im seeing a tutorial cuz im new on unreal)

[dawn gazelle]

Halt all movement is something you'd need to build

Whatever code you're using to move, you'd make it stop, and prevent it from moving.

[late cosmos]

oh, ehm... how?😅

[dawn gazelle]

First you'd build something where the actor moves towards the player.
Then you'd throw in some code so it stops and prevents moving towards the player when it is recently rendered.

[late cosmos]

ok ill try, thx

[mighty ravine]

Gonna keep working on this later this evening.
May have found a solution, not sure, we’ll see.
If it ends up working I’ll reply to the post here.

[fluid crescent]

The fuck?

[surreal peak]

Any more info than that?

[fluid crescent]

What should i provide?

The controls get reversed when i die

W and s

[surreal peak]

1. What is teleporting you?
2. What do you do when it teleports you? (code)
3. How are controls set up? (proper screenshot)
4. How are the controls actively applied (code)

[fluid crescent]

Ok wait a sec

this teleports me

my movement

[late cosmos]

how i can make the ai stop when i see it? @dawn gazelle

[fluid crescent]

shiiit @surreal peak i played around VR camera some time ago thats the problem 100 %

i'm pretty sure this is the problem

hello can someone explain me why my character falls from the map and dosent start at the player start when i die before i reach a checkpoint?
when i reach a checkpoint and die everything is ok

[finite hearth]

Interface question:

I understand at a high level that an interface is just a shared function and in general is more performant than a "cast to". But I'm curious on best practices - specifically, when is it okay to use a cast?

Should I just be writing interfaces whenever I'd cast or is there some general rule that I can follow to determine if and when an interface is more appropriate?

[fluid crescent]

anyone know what i have to do here

nvm got it fixed

well now i have a second problem

i can only die once for some reason

[late cosmos]

you just created an hardcore mode

lul

[fluid crescent]

haha

i litteraly go into negative health

its so embarassing being a noob here

[late cosmos]

ik

[fluid crescent]

it reminds me of my little sister

i honestly think it's dumb not to know how to change minecraft gamemodes

[late cosmos]

ahahha

[faint pasture]

Don't use delay

just compare the vector with the vector from last frame (save it)

(Current - Old) / DeltaTime = YourInputVelocity

[faint pasture]

Don't worry about performance WRT casting, worry about dependencies and general code structure

using an interface implies casting behind the scenes anyway

[earnest vigil]

Anyone have any idea how to calculate the bounds for the OPP bounding box? It doest seem like unreal gives us any nodes to get that

[lunar sleet]

What’s OPP?

[earnest vigil]

Like the local bounding box of an actor. When you use the get bouding box node it gives you AABB box which usually shows up as blue and resises when you rotate the actor to fit because the box itself does not rotate. I need the local box that will rotate with the object.

[steel geyser]

hi guys tell me is "Our vector" is object of class Vector 2 here ?

[austere ingot]

can you use bp to mass edit a data table? not during runtime just in engine to update the names or another value in a data table in mass

How to stop sequence when loading another level

[floral stump]

packaging a game starts compiling shaders, is it normal?

[spark steppe]

isn't that 5.x UI? :>

[floral stump]

4.26

[spark steppe]

anyways i wouldn't be too concerned

it may depend on what render piplines you have enabled support for

and eventually shaders for packaged are more optimized 🤷

[floral stump]

i also have no clue about it

all the shaders were compiled when i was playing the game in the editor

starting packaging, it starts compiling shaders again 🤷‍♀️

[lofty rapids]

"focus part" ?

[willow cedar]

What would be the best way to send which Collision is being overlapped for Apply Damage? I need what happens to be different per what is overlapped (Damaged)?

[manic summit]

I figured out the issue

[lunar sleet]

Use the overlap nodes and cast to the class of object you want to check for

[manic summit]

But I have a "Power generator" that makes noise when "E" is pressed, but how do i make it when E is pressed again that it will turn off

[manic summit]

this is for my third person bp and the first ss is from my static mesh bp

[lunar sleet]

There’s prly a stop #audio node

[lunar sleet]

That was a hint for you to ask in that channel

[manic summit]

lol ok

[lunar sleet]

As for the on/off, you can prototype with a flip flop, but switch to a bool w/ branch to make sure it works properly every time

[manic summit]

ok thanks bro :)

[hexed scroll]

I'm trying to draw a grid on my UI for an inventory system using OnPaint Override in a widget, but for some reason the grid isn't being drawn. I've done some troubleshooting and can confirm that all the needed information is getting passed into my Draw Line node, but it just doesn't do anything with the information. Any idea what could be causing this issue? Here's a screenshot of my OnPaint Override if that helps!

[carmine peak]

im probably dumb but i have a widget blueprint and i want to set view target with blend and how can i reference the character actor?

its late and i cant find anything and help would be aprecciated

[manic summit]

it was so simple 😭

ive spent hours searching youtube and other sites

then i find some small looking forum that had all the answers i needed hahaha

[kind estuary]

Im spawning these buildings randomly in the map. Though its not very uniform. Is there a way to make them spawn uniformly?

[carmine peak]

oh come on

why now

[rugged sonnet]

Hi everyone, I have some lights that I'd like to convert to spawnable but during playtime (not with the sequencer). I can achieve this with Blueprints, but it's quite cumbersome. I have to manually position the lights, adjust the intensity to nice values, and in the end, to make these lights spawnable, I essentially have to recreate the lights in Blueprint from scratch and pass position, rotation coordinates, adjust intensity in Blueprint, which is very slow and time-consuming. Is there any function similar to Sequencer that converts an existing actor into spawnable? If this doesn't make sense, could you please explain why? Thank you.

[spark steppe]

there's an editor feature for that, but i guess you still have to position them when spawning them again

but at least it would save the settings of the existing light

https://www.youtube.com/watch?v=npiQhoAoOM4

get sure to pick harvest components instead of child actors

i think even the first one uses child actors (which are a recipe for disaster)

[rugged sonnet]

Thanks a lot Ben, will look into that.

I just saw the video, maybe what I was asking doesn't make sense but the idea was to have less clutter in the Outliner, so image I have a bunch of lights, if I convert them to spawnable, they will go away and only show in play.

[dry sleet]

I'm not sure entirely what you're after, but Level Instances might be a good option.

You can convert a selection of actors in the scene into an LVI, which you can then clone out into the scene just by dragging it.

(https://docs.unrealengine.com/5.0/en-US/level-instancing-in-unreal-engine/)

I think there's an option to collapse the instanced actors when viewed in the outliner, if de-cluttering is key.

[fluid crescent]

happens after i playtest the game, should i be worried?

Hey helping heroes, Quick question: How do I get to the PlayerState from the actor pawn. Always struggeling with this

[earnest vigil]

Hey all. I am trying to get the red/orange bounding box that is the local bounding box from this object, but the only node that unreal seems to have is to get the blue world space one. Any idea how I can get the local bounds of an actor?

[twin perch]

So i want to spawn some instanced static meshes into the world (tiles)
the first is the test,

but when i spawn the tiles in they appear, but i cant find the instanced static mesh component

are they stored somewhere else ? the tooltip says it assigns ownership to the actor this is called for, so shouldn't it appear underneath ?

the only way for me to delete the instanced static mesh once i create it is to delete the entire actor.

(i am createing these in the editor)

[hollow cove]

from a character or an actor? how is the actor spawned? if its a pawn you should be able to get player state node and then cast to it

[lunar sleet]

Just rmbr to switch that flip flop to a bool eventually

[quick imp]

Has anyone set an animation blueprint in a datatable and then pull it from that datatable and set it to the skeletal mesh in a character blueprint?

[fluid crescent]

can i delete the collision of this

so i can walk through it if the tree is upside down

ahhhh found it found it

[rigid tundra]

1 Image: Programming reference to the Collision Sphere in Metahuman

2 Questions:
Why is BP_ThePoliceman missing in example image 2?
And why is it duplicated in image 4?

Context:

The variable Conversation Sphere is set via Instance Editable & Exposed on Spawn
The variable GroupNPCConversation is a component added on the Metahuman

It seems that some references get lost during the set of the reference variable ConversationSphere

[wraith loom]

Simple question, I want to set off code in a default blueprint object class from another class. I got a blueprint interface, but I need a reference to the other class. How do I get that reference? I feel like I should know this but my brain is dead rn.

[fluid crescent]

how to make this string appear as long as i am in this box?

[wraith loom]

You can probably use the "actor end overlap" event to set a boolean to false

[fluid crescent]

ok thx

[remote wasp]

I have this flickering issue in my game when I set this actor to hidden
Anyone know if I can fix that?

[zealous moth]

is it double sided?

what i would do is make it disintegrate slowly instead of flashing it

[remote wasp]

it's a static mesh

it's either there or not there

and either way i'd have the same issue, the problem here is that the meshes that are out of vision are culled, and they don't reappear quick enough when they suddenly become visible

[deft tusk]

anyone know how to create a loading screen until level load is done when streaming levels? Prefreable with blueprints only no c+

[surreal peak]

If it's just streaming levels and not actually traveling you can just show a widget until the callback for when the level is loaded comes back. Pretty sure the nodes and classes involved have pins and callbacks for that

[wintry meteor]

for this part which is get HUD as you mention, what should i replace it with to get input and references of everything from actor class?

can anyone help?

[dawn gazelle]

Assuming you've properly implemented that interface in your actor, then you need a reference to the actor that you want to call that interface on.

[wintry meteor]

something like this?

or is there another ways to get references from actor

[deft tusk]

ok so what node would check for level load completion?

I dont do lot of programming

[dawn gazelle]

Something like this, yes... But what you have here is setting a reference to itself, and I doubt that you've actually got a reference to the actor. Look in the pins on this channel - near the bottom there is a "blueprint communications" video - it's a long one but it teaches you how to get and use references and communicate between blueprints.

[blissful summit]

Is there any function in UE that checks for corrupted blueprint?

Last time I had a corrupted blueprint the only reason i caught on as soon as it happened was because the light settings were bright as hell (it was a custom light BP)

couldnt imagine how i wouldve known if it was a none visual BP

[quick imp]

Has anyone set an animation blueprint in a datatable and then pull it from that datatable and set it to the skeletal mesh in a character blueprint?

[frosty heron]

yes

You are just reading data from data table, what's stopping you from assigning the Anim blueprint

My DT

[main lake]

Could someone tell me why this code produces a "None" value even if I used a validated Get and also how to fix the first error please ?

[fiery swallow]

if you're doing this on a dedicated server, then that's why

dedicated servers don't create UI

[main lake]

I'm not, the netmode is set to "Standalone". What's the proper way to do that then please ?

[fiery swallow]

it literally says "is not local player controller" bud

you sure you doing it in standalone?

[main lake]

I wrote the code in my PlayerController, could that be the reason ?

[fiery swallow]

no, listen servers are allowed to have widgets.

Are you like, joining a game and then creating this hud?

because even if you start the game as standalone, and then join a session, immediately it is no longer standalone

[main lake]

yes

how to properly write my code then please ? Becaues my game won't be on dedicated servers I think but rather on player hosting a game for everyone

[fiery swallow]

check that the controller is local before running the code

should be some node called "is local controller"

or something

[main lake]

wouldn't that make the host of the game not having UI ?

[fiery swallow]

local != client

so no

[main lake]

but I need the host to also have the UI

[fiery swallow]

my mans

the host will locally spawn it's own UI on it's own controller, and so will clients

[main lake]

then I'm confused by the error

[fiery swallow]

just check if the controller is local before running the code

local just means it's not networked to someone else

think of local sort of as "does this belong to me?"

[main lake]

which one should I choose ?

[fiery swallow]

is local controller should be fine

player controller is just a child of controller

[main lake]

Like this ?

[fiery swallow]

You can't get the owning player of a UI that doesn't exist

assuming you're doing this inside of a controller class

https://i.gyazo.com/b9a843de3414613fd280efaac3fba527.png

the true branch will only fire for the person who owns that controller

everyone else, including the server (if the server doesn't own that controller) will return false

[main lake]

so like this ?

[fiery swallow]

yes

[main lake]

thank you 🙏

I have another problem with my "Refresh" button, it always needs to be pressed twice before showing the available session, do you know why please?

[fiery swallow]

well first off all you aren't even using the "On success" pin

that's a delayed node, it could return the results sooner or later

so you need to wait for it to succeed first

[main lake]

You're the GOAT 🙏

[fiery swallow]

lol

[main lake]

Are you good a bit with stuff regarding "Character" rigging ? Because I need help on how to properly set up a character before importing it to unreal 😄

[fiery swallow]

sorry buddy I'm done with unreal source for now. my league of legends game is starting

[quartz kayak]

Could somebody please help me to debug an issue with my movement system? I'm using Set Actor Location with the sweep option enabled. The issue is that the behaviour is quite strange as the player is unable to move through a corridor even though it shouldn't be colliding with anything?

[main lake]

Alright, thank you 🙏

[wintry meteor]

i see, alright i try check it

[lethal pollen]

Hi!

I have a Blueprint class which inherits from a C++ class:

I want to re-parent the Hand Right and Hand Left components with another blueprint class (which inherits from Skeletal Mesh Component). Hand Right and Hand Left inherit from USkeletalMeshComponent.

How can I do it?

Thanks!

Hey , i can't call cast my tool in object class.
I'm trying to make a quest system here, but I can't reach what I collect with the tool in the object class.

[lunar sleet]

I don’t rly understand what you mean. Is the cast failing or what’s the problem

[silent stag]

It's not calling this hatchet cast

[lunar sleet]

Wdym it’s not calling it, why are you saying “call cast”

[silent stag]

because i want to reach this bool at the left picture

[lunar sleet]

A cast is a type check. It checks if the ref you fed it is the right class and if so lets you access its insides. It doesn’t call anything

So, is the Cast Failed pin firing?

[silent stag]

yes it's stop on cast

[lunar sleet]

Then whatever ref you’re feeding it is not the right object. Where are you setting that ref?

You can use breakpoints and hover over the input and output pins to see what object the ref is pointing at btw

[silent stag]

i used object parent class of hatchet

[silent stag]

I did not set anywhere on that object class

[lunar sleet]

Where is Tpequipref being Set ?

[silent stag]

Nowhere

[lunar sleet]

Good, now you know what the problem is.

[silent stag]

Should it be on that object class ?

or hatchet class ?

[lunar sleet]

It doesn’t matter if it’s the parent or the child, provided that the variable you’re searching for exists in both. But you need to get an actual ref to that instance and set Tpequipref to it. You can’t just create a variable of class X and try to cast to it, that’s now how it works

Usually you can get a ref by interacting with the object using line traces, overlaps, hits, etc.. There are other ways but some form of interaction is your safest option

[silent stag]

then i dont need to parent class

i will try to set hatchet first

[lunar sleet]

That’s fine, just get a ref to the hatchet and then you can cast

The 2nd to last pin in this channel teaches you how casting and other bp comms work btw, worth a watch

[silent stag]

Thank you so much man

[wanton prism]

Can someone help? I am making an objective system from scratch.

[silent stag]

engine saying you dont need to cast using already this ref with this way

[lunar sleet]

With which way?

[lunar sleet]

Define the problem, can’t read the spaghetti 😀

[thin panther]

of course. if your ref is already of the type you're casting to, then a cast isn't necessary

[wanton prism]

i didnt even call the object event

lol

[thin panther]

it's like saying
"Hey could you tell me if this car is a car?"
"......"

[silent stag]

yeah i now but we just talk this

anyway it does not work man

i set that in event

let me try parent class to set

and then cast from that

[lunar sleet]

I still see no interaction, how are you getting the ref

So far you just used Get and Set together which does nothing

[main lake]

Why this part of my blueprint keeps printing 9 when the value of "MaxHealth" is 19, while "ceil" is supposed to round upward and not downward ? 🤔

[wanton prism]

I have had this problem for every single time i have made an interaction system with objects?
