blueprint

[crimson briar]

Each ISM component is a separate thing. DOesn't matter if they have the same meshes or different ones

[dusky cobalt]

so it's literally jsut for visual objects and cannot be used if I have something that can be clicked on etc.

each actor should register itself, display it's static mesh in ISM component, but have separate logic for something that detects the collisions for clicking on it? maybe this Instanced Actor will be what I need

[crimson briar]

Depends how you build it. I made a simple mine with HISM at one point (it is an expanded version of ISM, allowing for some individualism on the meshes) - eahc block in the mine was an instance of the HISM and I was passing to the actor holding them a reference to which one was hit, and the actor was holding all the data what was supposed to drop from it

[dark drum]

Sort of yea. You can do a little with it but one method I've tried before is swapping out an instance for an actor when the player is looking at it.

I believe the Instance Actors does something similiar based on distance. (Not looked in to it though)

[surreal peak]

I mean, if you end up with just 1 instance per ISMC on each Actor, then you might as well not use an ISMC here. So having a central Actor with a central ISMC that allows adding/removing instances would be the better way.

Iirc UE does already convert some meshes into ISMCs when cooking/packaging, but don't have a source at hand.

[dusky cobalt]

that's rough since imagine top down game with a building, you want the player to see reaction exactly as you hover over it's mesh, right? not some collision that isn't exactly the building shape or is smaller or bigger?

[dark drum]

I think you're right but only for the 'static mesh actors' you get when you just place just a mesh in the level.

[surreal peak]

What does that have to do with ISMC though?

They still have collision and Materials allow per instance data.

[dusky cobalt]

so the actor still can access the instance it added to the ''manager' actor that has the component?

[surreal peak]

So it's not like 1 ISMC means you always interact with a solid piece that consists of all instances.

[surreal peak]

Well yeah, you gotta code that boilerplate setup of course.

That Manager might also want more than one component and add/remove them dynamically, as one component means one mesh asset.

[crimson briar]

I believe OnHit event has a value for the index of the ISM part that was hit if you ever need that

[surreal peak]

Yeah it does. One just has to then route that back to the right actor.

[dusky cobalt]

oh that's interesting, i have to test that then

[surreal peak]

And for hover effects, or outlines or stuff like that, one should be able to use the per instance data in materials.

But I'm not a material person.

[dark drum]

Just be aware adding and removing instances can change the indexes so you can't normally store them.

[dark drum]

I've done this by having a hover actor that gets the mesh from the ISM and places it in the same place.

[dusky cobalt]

I also can have 1 manager ith like 3 instances component and then each thing find the component it needs to 'add' itself to?

[surreal peak]

If you have a Mapping between Mesh Asset and ISMC, sure. Again, up to you to code the boilerplate for this.

[dusky cobalt]

okay

thanks for help, will try to do something with that

[dark drum]

I think I have an old tutorial that does this. 😅 Granted I'd probably do it differently today but it might give you some ideas if your interested.

[dusky cobalt]

Ill take a lot, thanks!

[surreal peak]

Relatively sure they added something for that.

I would need to read the code once more but there is a mapping between the index and Ids.

[dark drum]

If you get a moment to point me in the direction for that, I would be grateful.

[dark drum]

Let me just find it.

[dark drum]

This one, it's for a maze generator but you should be able to ignore that part. Again it's old and I would do many things differently today. (Using soft refs for the keys for example)

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

[dusky cobalt]

I guess half of this api is not avaliable in blueprints?

I managed to quickly prototype just adding instance of X static mesh at X location (each actor calls to manager), but how can I somehow return the instance reference back to the actor that requested adding it to manager?

[dark drum]

The stuff eXi shared looks like its C++ only.

[dusky cobalt]

Okay, so before I dive into that. I'm gonna be able to do that when this Instance got hit by something(line trace let's say) to call to the Actor that added that instance in the first place?

[dark drum]

You can add an output on the AddInstace function that returns it. Just be aware that it might not line up to the right one if an instance is removed.

[dusky cobalt]

yeah I would probably create some TMap with ActorRequesting - Static Mesh Instance so they it can be pointed toward the c orrect one, but is this even possible what I need to happen?

[dark drum]

Possibly, you could have an array that stores the relevant actor at the same index. If you remove from the ISM, you remove the same index from the other array.

[dusky cobalt]

Hmm, other way would be maybe to add the mesh to render under the ISM component (in manager), but have collision of the shape of the mesh so it works 'on actor' ?

I guess my question would be if having Static Mesh but render Hidden In Game makes it not have draw calls?

[crimson briar]

Huh. I think in my mine project I was storing the data related to the instance in the Vector -> Struct map, where the vector was the location of the Instance. So I didn't even know you can't rely on the IDs when adding/removing lol

[dark drum]

Being hidden means it won't be rendered. (no draw call from it)

[dark drum]

I've done something similar before but as an int vector to help mitigate floating point errors. I never liked this method though. 😕

Kevin has been slacking. 😅 I love finding this type of stuff. 🤣

[dusky cobalt]

gg then, it's gonna be exactly what I need

render in manager, leave logic in the actor

[dark drum]

Whats the end goal? As in what are the actors and what would they be doing?

[dusky cobalt]

So they are resources in rts game, so you need to be able to select them or click on the to send workers etc.

and I will probably do the same with buildings but just have buildings manager

[last peak]

Its so much fun to create rts games

Very satisfying when the ai does what its supposed to 😄

[dusky cobalt]

do you have experience with that? 😄

[last peak]

Just with prototypes
https://www.youtube.com/watch?v=rjAjsPCga4w&t=1

A few years ago i created a prototype for every genre that interested me and rts were the most fun to make

[dusky cobalt]

omg im dying hahah, the voice lines

love it, would play 10/10 😄

[faint pasture]

Your code is saying to not apply a radial impulse of radius 0 to nothing

the rare triple negative

it's doing nothing in 3 different ways, at least.

[timber onyx]

I was playing with the nodes, here is the latest version

[faint pasture]

10 is a tiny velocity

assuming the strength = velocity change with those settings

10 is 10 cm/sec

not very fast

try 10,000

then turn it down if that's a bit much

btw draw debug point at ImpactPoint to make sure it's even hitting where you expect

[timber onyx]

i did this and the cube disappeared Xd

okay, i guess it works now.

thanks man

My goal is to trigger the fracture in fractured meshes but i think this is not the way it seems.

[faint pasture]

AFAIK strain is what does the fracturing

Never done destruction but I've done a ton of rigid body physics

[timber onyx]

I've got this physics enabled cube that can smash through fracture

and I can push it with impulse

but impulse does nothing to the fractured objects

[timber onyx]

say, is there an alternative way to maybe do this without destruction

I'm doing a stress-relief type of game where you can smash the office props

[faint pasture]

nah destruction is what you want for that

[timber onyx]

hah alright!

[faint pasture]

Back up and get the basics down, make aiming at a thing and clicking the button bust it apart

[timber onyx]

I can throw the cube and it can smash through anything. It seems i'm close to the objective :-) Thanks!

[barren tangle]

Is there a way to know why that node fail ?

[crimson briar]

In blueprints - I don't think so. From a quick look C++ PathFollowingComponent has some more stuff but I don't see a way to access it via blueprints

Also I'm not sure if it would be visible in the AI Debugger but you can try to open it during PIE and look if there is any relevant information there

Can anyone give some advice on this problem? seems so simple but its making me crazy

[urban creek]

Hey everyone. I have a random but important question that is related to Unreal Engine. I've been using the engine for almost a year and I freaking love it. As I learn, I've encountered one major obstacle that's been the bane of my existence. I don't know how to program and I was drawn to Unreal Engine because of Blueprints. I love that about the engine but I learned that if I use any plugins that have C++ classes, I can't package and compile a project. This has really limited me and I've tried for months to figure out how to properly install and connect Visual Studio for Unreal Engine but it's been difficult, to say the least. YouTube videos and other people on forums haven't been that helpful and I know it's a lot to ask, but it would be amazing if there is someone who is willing to guide me with the set up of Visual Studio for Unreal Engine. I want to do so much with this engine but the technical and programming stuff are not my strongest suit.

[abstract obsidian]

Hey guys quick question, anyone or have experienced this thing? : i added double jump to my character and its working without problems, the only problem is that if my character walk off from a ledge, the jump max count go from 0 to 2 without let me do double jump
I dont know how to fix it

[brisk pine]

happened to me once, and got fixed on its own after I restarted the unreal editor, if that doesnt work removing the navmesh and adding a new one should work

[barren tangle]

nothing, restart, delete

nothing solve the issue

[hidden pecan]

So I've run into this weird thing where I can plug my component variable into destroy component but not into "play animation" are there any nodes I could use to plug my component into play animation?

[spark steppe]

you would have to change the variable type to skeletal mesh component

right now it's likely a actor component or scene component variable (which is why one node accepts it, but not the other)

[hidden pecan]

Yup that fixed it got that part working 👍

[odd kiln]

Hey all !

I'm trying to call the same event with a "Delay" to Destroy Components

But each time I call the "Delay", it stops the preivous one..

Anyone knows a way to "Delay" multiple times without overriding previous ?

(I need to pass the "Component" parameter)

I mean it's like I want to "stack" some events and execute them one by one after a delay

For example : If I press "U" fast, multiple times, it should executes an event each time I pressed the "U" key but each one after its own delay without interrupting the previous ones

I don't know if I explain it well

[sand shore]

Make an array of components to destroy. When you want to destroy a component, add it to the list.

You wanna use timer nodes for this next part. When you first add a component to the list of comps to destroy, start a looping timer with your desired delay. Each time the timer event goes off, take the first component to destroy out of the array and destroy it. Check if the array is empty, and if it is, you can cancel the timer.

To cancel the timer, save its handle to a variable. If you have the handle as a variable, you can check the timer handle when you add a component to be destroyed- when it already is valid you don’t have to set it

Try your hand at this setup, and share the implementation in this channel if anything isn’t working

[ancient iron]

guys i am new to ue can you tell how i can use motion warping to get the rotation facing my enemy

i want this for my character blocking state help me

some time it work and somtime not

ignore background music 😅

[lunar sleet]

Watch 2nd pin video to learn how to use bp comms and set refs properly

[ancient iron]

bro i want that motion warping thing can you help please

[dreamy sail]

does anyone know why I have this issue with replication:

If I have a character BP enemy that turns into a ragdoll when I shoot it, after I shoot it a couple times once it's already a ragdoll, it's position won't replicate when it moves around from being shot, but if I grab it and move it around it will replicate perfectly

if I have an actor BP, with the same exact logic, it will replicate perfectly

is there a specific difference between character bp and actor bp when it comes to replication?

[crimson briar]

Maybe someone on #multiplayer could answer better but I think replicating physics is a separate checkbox on the components? Maybe you don't have it set up properly.

[dreamy sail]

all the checkboxes and settings are exacty the same. I posted in multiplayer, thanks, I missed that channel

[dusky cobalt]

try to Build -> BuildPaths or click P and see what is happening with your nav mesh

[barren tangle]

It’s the same

And the message is also with the P

[dusky cobalt]

did you try to remove ravcast mesh and nav bounds? and the P is just for displaying nav mesh so if you don't see it as green over landscape it means it's not generating

did you maybe change some collisions with landscape?

[barren tangle]

will check but it's just a normal cubes

[dusky cobalt]

they should block pawn I believe

[barren tangle]

it block everything

it's the first time i have that error

i alsways use normal UE block

to build the map, and it the first time the nav bound give me that error

[dark drum]

Sometimes the navmesh just dies. Delete the recastnavmesh actor that should be in the level. (Keep the nav mesh volume) Once done, rebuild your paths. This should generate a new recastnavmesh.

Just be aware that the recast nav mesh will use the default nav mesh settings.

[barren tangle]

thanks!!!

[pure gyro]

there is a plugin that links visual studio directly to UE otherwise you can directly open the project in Visual studio

[urban creek]

That's good to know

[serene marten]

guys pls explain me what is this bp? or how to get it

[thin panther]

you make it

that's calling a custom event called "headbob" on the character bp

[serene marten]

how to add a custom event?

[faint pasture]

just right click in the event graph and you'll find it

[serene marten]

where

or how to add a custom event here

i can only add a new graph

[faint pasture]

right click here

[serene marten]

then?

[serene marten]

this&

?

[faint pasture]

sure

you have made an event named CustomEvent and now can call it whenever you want

[serene marten]

but its other bp?

[steep oyster]

So you need to cast to it

Or set up an blueprint interface

[serene marten]

look, its a blue and text in bot

[serene marten]

oh idk how to do it

[steep oyster]

Type it in again in the sesrch bar

[serene marten]

type what?

[steep oyster]

The name of your Custom Event

[serene marten]

but i dont add this yet

because idk how

[steep oyster]

You already added it?

Right there

The blue things task is to trigger red thing

[serene marten]

yea i added but i deleted it bcs its not similar that bp in photo

[steep oyster]

"Headbob" isnt a function

You have to programm it yourself

In UE you have the ability to create these blue things and fill them with your own code

[serene marten]

but i checked a video in yt where is guy explain how to add a camera shake, then when he opens first charachter bp it already have a 2 blueprints

[last peak]

Its a custom made function, he made this off screen

[crimson briar]

It is what it is. Everyone can make a tutorial, even when they are not good at it

[last peak]

Probably the video was recorded as part of a series

[dark drum]

If you want a realistic head bob just attach the camera to the head bone. 😅 (There are pros and cons to this)

Alternatively, you can use camera shake objects and have different ones for idle, walk and run.

[polar barn]

I have this Widget BP where when the Intger Reaches X number it opens the next level it works for that part
but it ignores the has ticked Boolean and open over & over again
I know the Has Ticked? Boolean works because if I switch out the Open Level (by name) for a Print String it will only fire once
so is there a way for the Open level to only be fired once using the event tick

[crimson briar]

By default everything that is part of the level is destroyed when changing levels. So most likely you changing the variable doesn't transfer over to the next level, since the Widget is remade from scratch.
Also don't do critical logic in widgets.
You already have the variable on the GameInstance, why not handle level loading through the game instance?

[polar barn]

I already had the To Text setup where it shows the intger number on screen but if the level switching part will work somewhere else i will try that
Thank You

[crimson briar]

It can work in widgets, but a good practice is to leave widgets out of logic and use them only for displaying stuff.
The problem here though is that you use a variable from the GameInstance - GameInstance is special because it doesn't reset between levels - and then use it to determine level change in the widget that is reset each time level loads.
So the Set HasTickedOnce basically doesn't do anything.
And since you use the value from the game instance, the next time this widget is created and ticks, the value in the game instance is the same but the HasTickedOnce is back to being false

[obtuse mulch]

little math question

[crimson briar]

I'm not sure I understand what you are asking about here

[obtuse mulch]

well the timer value desides projectile speed

the lower the tick the faster it goes

i just want to make it easier to use

because Speed base value is 1

i dont want to invert the upgrade process

like 1 +10% is 1.1

makes Timer go actually slower

[dusky cobalt]

1 - (1*10%)

or x - (x*10%) if you always want to take current that you apply 10% to

[obtuse mulch]

way too long since i did any math 😆

ty

[dusky cobalt]

<@&213101288538374145>

[obtuse mulch]

the problem now that the value goes to 0

if upgrade is 100%

after 0.001

[dusky cobalt]

100% cooldown reduction is 100% cooldown reduction, no? 😄

you can clamp with it beeing 0.001 if you want

so it won't go to 0 but won't go even less

[obtuse mulch]

nah its like proj speed is 1 , and 2 isnt the max

[dusky cobalt]

if you take 1 (1- x % ) always and x% is 10% then it's gonna take 10 reductions to go to 0

[obtuse mulch]

need timer to go 0.0009

meh whatev ill figure it out the hard way

[tight pollen]

hi, someone can look at #metahumans

[faint pasture]

Time = BaseTime / Speed

if the thing is meant to take 5 seconds and you have a speed of 2 (100% bonus) then your time will be 2.5 seconds

if you intend your stat bonuses to be as percentage, i.e. 30 bonus speed is a 1.3x on your speed stat, then do it like:
Time = BaseTime / ((1 + Bonus)*0.01)

I'd normalize everything to a 1.0 base.
A speed of 1.0 means normal speed, unmodified.
Then it can just be Time = BaseTime / Speed

[crimson briar]

I'm still not sure what he tries to do, but here is my old fire rate script, maybe it will help. The return goes into a timer as well

[faint pasture]

You can display whatever you want but at the end of the day the Speed stat should be some float from 0 to infinity

[cunning vapor]

Nice scam

Hello 👋
I hope someone can help me out as I cannot find a solution to my issue.

I have a packaged game on Steam which has co-op elements.
I am currently running into an issue where I am not able to normally start up a round in coop with 2-3 players.

Loading into the lobby works fine for host and clients. As soon as I start the gameplay map, either all players or all except the host receive a "Fatal Error" message and the game crashes.

I think it used to work fine but does not work anymore nowadays, even though I believe I have not touched anything regard the multiplayer logic in BP.

Could someone help me out? It would be greatly appreciated!

I launch the game here when the host presses the launch button.
Image 2: Here is the Server Travel logic.
Image 3: This is the game manager in the new map which then does logic stuff.
Thanks!

Hye guys, is anyone else having problems downloading android studio? I cant open the link. Does anybody know how to fix this|
https://developer.android.com/studio

[storm solar]

Any idea on this one?

[maiden wadi]

You can make a parent ABP with the events you need.

But you can also just make the ABP itself bind to Character's movement mode and callbacks for Landing or Apex Reached, etc. Your Actor shouldn't have to tell the ABP what to do usually. The ABP should be able to bind stuff it needs to function independently.

[maiden wadi]

The crash in question would also be helpful. Not immediately obvious what the crash is about. It may not even be related to the code you've shared.

[zenith ocean]

Yeah, I am not able to find the crash logs. Since it is already distributed on Steam I have no idea where it is.. I thought maybe appdata but the logs folder is empty.

[maiden wadi]

Is this a 3D world space widget, or a screenspace one?

[maiden wadi]

Check your game's installed directory's saved folder too.
EG
steamapps\common\Atre Dominance Wars\DominanceTOE\Saved\Crashes

[storm solar]

Do you have an example? Im not able to get anything in this blueprint / owner pathing to bind to animation apex.

[zenith ocean]

Maybe this? However it is not in the steamapps folder.

I have this in a crashes folder in appdata, but this does not tell me much

[maiden wadi]

Check the XML. Search for a <CallStack> and hope it has something there.

[zenith ocean]

Does not make much sense, they all look similar

[maiden wadi]

I misread this as being the jump apex, not an animation. what is your use case with this? I'm still leaning towards the template animbp.

[storm solar]

I have an anntack animation that casts a spell (projecticle object) when this notify is called with a notify. It needs to know what mesh/ animation to play when the notify is called. As of right now, it only works for one type of model/ mesh.

[maiden wadi]

Rough. Not sure what causes those to show. But you'll need to find a callstack somehow for the crash.

[maiden wadi]

You mean like a hit montage? React to the projectile hitting them?

[zenith ocean]

I have this one which says true in isCrashed, but it just says GameThread. Not even sure if that reallly is the issue.

[maiden wadi]

You're looking for things more like this where you know what the last function was that caused the actual crash.

[zenith ocean]

I fear I somehow don't have that. Maybe I disabled logs in the settings.

[zenith ocean]

I now included a reporter but this one also does not tell me anything lol

[maiden wadi]

You may need symbols installed. I'm not sure if that also helps with cooked crashes.

[surreal peak]

@zenith ocean Btw, crossposting isn't allowed. Please don't ask the same question in multiple channels next time.

[zenith ocean]

Ah, sorry about that! I figured I posted in a not so fitting channel, which is why I posted in the other one. Noted!

[surreal peak]

Since you are using a Shipping build, and that over steam, there is probably a high chance that you have no pdb files (especially if this is a BP only project) available when it crashes.

I would suggest you create a development build and try that. Doesn't even need to be uploaded to steam.

Good chance that will crash as well, and then with a proper callstack.

[zenith ocean]

Alright, I'll try it tomorrow again and check. Thanks for the hint. Will try a development build 🙂

[surreal peak]

Usually, Widgets are cleaned up upong travel. Not sure what the rules are around Hard vs Seamless-Travels, but you would usually want to use the MoviePlayer module to play a "Movie", which allows specifying a Widget.
That's C++, but there should be Plugins for this by now.

[surreal peak]

I'm looking at it and I question it myself.

Actually, I guess the idea is that you can use FRuntimeFloatCurve if you don't want to make a new UCurveFloat asset just for one single usage case.

But then again, the EditorCurveData isn't even exposed to BPs...

[cerulean mortar]

So I use the RuntimeFloatCurve when I want to reuse the same actor with a different curve for each one in the level?

[surreal peak]

Hmhmhm looking at the usage of the Editor part, I think they are using FRuntimeFloatCurve if they want to manually edit the FRichCurve EditorCurveData in C++, but allow the user to supply an override via their own UCurveFloat asset.

[surreal peak]

Na, I'm just throwing out ideas. I think for Blueprint users it doesn't make a difference tbh.

[cerulean mortar]

Oh I see, thank you!

[surreal peak]

I think it's solely for C++ to have a base curve and then the optional "External Curve" that a user could specify.

So if you are in BPs, just use the UCurveFloat directly.

[dark drum]

Curve is just a wrapper to get the runtime float curve into the control rig BP's I believe. If you break the 'Curve' var type it'll say something like 'Rig VMFunction Anim Rich Curve'. This naming convention is normally related to the control rig stuff.

[cerulean mortar]

So In a normal blueprint they'd be basically the exact same thing?

[dark drum]

I would imagine so. A 'Curve' has a Runtime Float Curve inside.

[cerulean mortar]

Okay thank you! :)

Hello, trying to make a PawnMovement Component - followed a brief tutorial on it to get some bearing.
In terms of CPP, all I did was taking code from CollidingPawnMovementComponent.CPP From Quick Start Guide to Components, made a FVector and float for max speed, and put it in TickComponent.

Basically everything other than gravity is working - which is being done in the Pawn Actor Blueprint.
I have tried instead of this custom Vector, putting it to velocity but that didnt make a noticeable change.

The link to the video i followed:
https://www.youtube.com/watch?v=W5fXxSZUIfs
Quick Start Guide to Components, for the code i put in the custom component, Part 5:
https://dev.epicgames.com/documentation/en-us/unreal-engine/quick-start-guide-to-components-and-collision-in-unreal-engine-cpp#finishedcode

My screenshot of my BP Code and a video of what happens, which is basically it just floats.

[dark drum]

How is desired movement this frame used?

[vernal snow]

it is used by the Ramp Movement Component in the Header and Source file.

In the blueprint, its just trying to say "hey, if true .z Do nothing / false .z move down"

In the Source file, its literal a copy paste of what was from Quick Start Guide - aside from setting the DesiredMovementThisFrame as a variable in Header and float MaxMoveSpeed.

void URamp_MoveComp::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
    Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
 
    // Make sure that everything is still valid, and that we are allowed to move.
    if (!PawnOwner || !UpdatedComponent || ShouldSkipUpdate(DeltaTime))
    {
        return;
    }
 
    // Get (and then clear) the movement vector that we set in ACollidingPawn::Tick
    float DesiredZ = DesiredMovementThisFrame.Z;
    DesiredMovementThisFrame = ConsumeInputVector().GetClampedToMaxSize(1.0f) * DeltaTime * MaxMoveSpeed;
    if (!DesiredMovementThisFrame.IsNearlyZero())
    {
        FHitResult Hit;
        SafeMoveUpdatedComponent(DesiredMovementThisFrame, UpdatedComponent->GetComponentRotation(), true, Hit);
 
        // If we bumped into something, try to slide along it
        if (Hit.IsValidBlockingHit())
        {
            SlideAlongSurface(DesiredMovementThisFrame, 1.f - Hit.Time, Hit.Normal, Hit);
        }
    }
}

[dark drum]

From what I can see, you extract the Z into its own float var and then override the desired movement this frame with the movement input stuff.

I can't see where the Z movement is ever added back in and used.

Adding to this, it doesn't look like there's any logic to handle acceleration/deceleration, terminal velocity etc... that would normally be required.

[vernal snow]

Yeah, I see that logic. we dont use the Z movement in the Cpp.

The z Movement is being moved in the Pawn's blueprint, via the ground check.
I just followed the video. It did worked for floating pawn movement Component, IE the Blueprint stuff.

But when following the steps for Cpp it didnt work, messed around a few times trying to figure out if something else was overiding it.

Don't have much an answer for acceleration/ terminal velocity, havent changed that in any capacity.

[dark drum]

The Z movement isn't being moved in the pawn BP. What you're doing is setting the desired movement. These changes are then disregarded in the movement component.

In the C++ class, you need to add back in the Z value after you've applied the input movement stuff.

I played around with some custom gravity stuff for physics actors where I had to apply gravity myself. Let me grab a few screenshots. It might help point you in the right direction.

Its on oldish project so go to wait for shaders to compile. 😅

[dark drum]

Just checked and it won't help. 😅 I just use the add force function.

[vernal snow]

Right, okay.
Thats fine but no, you regardless helped me.

I did what you said, works now. It was a silly oversight of missing a line.
Thank you for helping.

[merry shell]

Can Anyone make EQS for me in which NPC investigate the last known location of seen\heared target in a realistic way like find around hiding spots where target can hide so the npc find target on that places only. Please anyone help me

[last peak]

eqs?

[merry shell]

Yes

[dark drum]

Enviroment Query System

[last peak]

oh

[merry shell]

Please help please

[last peak]

thats not that easy

[dark drum]

What is considered a hiding spot?

[merry shell]

Like behind the walls and any hiding spot around last known location

[last peak]

are the hiding spots actors ?

[merry shell]

yes like walls and others

[dark drum]

You need to be a little more specific at defining what a hiding spot is. Behind a wall is pretty much everywhere.

[merry shell]

I don't understand please make it clear??

[last peak]

You will have to work with perception

Ryan Laley has a good video on Ai perception, what you have to do is get the players last location before the ai lost sight then you make it walk to all hiding spot actors in that area
https://www.youtube.com/watch?v=bx7taRBjJgM

[merry shell]

is hiding spots eqs available in this

[dark drum]

All the red dots (any many unmarked) could be considered hiding spots if the only condition is behind a wall.

[merry shell]

Consider nearest distance & handle context of eqs I don't know help plese??

[last peak]

How can we know if you yourself dont know 😛

[merry shell]

I Know but i am not able to understand others

[dark drum]

You need to be more specific about what you would define as a hiding spot. Behind a wall is too generic.

[last peak]

put it in chat gpt and let it explain the text to you

[merry shell]

Ok i will try

[merry shell]

I am trying to implement a realistic AI investigation behavior for my stealth game using Blueprints and Behavior Trees, and I would appreciate some guidance.

My goal is to create an AI that feels more intelligent and less predictable, inspired by realistic scenarios (like in Money Heist).

Current Setup: My AI can successfully see/hear the player and chase them. When it loses sight, it correctly gets the player's Last Known Location (LKL) from the Blackboard and moves to it.

The Problem / What I Need: When my AI reaches the LKL, it just stops or idles, which is very unrealistic. I want the AI to actively and intelligently investigate the area around the LKL.

Here is the detailed behavior I want to achieve:

Trigger 'Search Mode': When the AI reaches the LKL (or near it), it should switch from "Chase" to a new "Search Area" state.

Use EQS for Hiding Spots: In this "Search Area" state, I want to run an Environment Query (EQS). This query's job is to find potential hiding spots (like corners, closets, under desks, behind crates) in a 10-15 meter radius around the LKL.

Get Multiple Points: I want this EQS query to return a list of the best 5 to 6 investigation points, not just one.

Systematic Investigation (The Loop): The AI should then systematically visit each of these 5-6 points one by one.

My Questions:

What is the best way to set up the EQS Query to find these "hiding spots"? (Should I use "Actors of Class" with a special tag, or just "Points" with context tests?)

[merry shell]

now??

[last peak]

If the hiding spots are actors you can just look for all hiding spots in an area around players last location then let the ai visit each one of them, if every wall is a possible hiding spot and hiding spots are not actors things get more complicated
You would then have to find all spots where line of sight is blocked and visit them like that

You could also just make it randomly search an area no matter if there are hiding spots or not

[crimson briar]

I believe there is a function to find a random navigable point in radius? Or something like that. You could make a loop to use that, then use a trace towards the found location - and check if the trace was interrupted - meaning the locaiton is behind something, so go there. If the trace is not interrupted, look for anothe random navigable location in radius

[dark drum]

Do anyone have any ideas why setting a soft ref inside a data asset from an editor widget doesn't actually get saved? When restarting the editor, the value is cleared. If i manually set the soft ref, it persits during editor restart.

[crimson briar]

As to making it "intelligent" well it is your job as a designer, isn't it?

[merry shell]

it returns all reachable points but I want only points where a character can hide himself.

[dark drum]

And from those reachable points, what would define it as a place the character can hide?

[wild moth]

Hello,
Simple question but is it not possible to make the Blueprint regular OR/AND behave like a regular || && where for example in OR if the first condition is true the others won't get evaluated?

I mean I just tested it and setting the first pin as true keeps executing the second one which sucks :/

[last peak]

What?

[dark drum]

Short answer is no. Its because of the CommutativeAssociativeBinaryOperator flag the function has. This allows it to have the 'Add Pin' functionality but means that the order doesn't matter.

[wild moth]

ah I see, bummer

[last peak]

How would the order matter in not blueprints ?

if (a > b || b > a)

[wild moth]

in c++ for example if you do if (A || B) if A is true then B isn't considered

that's what I'm talking about

in Blueprints it doesn't respect that, it'll test all of them

[last peak]

And what is the benefit of that ?

[wild moth]

if for example A is a super quick and cheap check and B is a more expensive/complex check

[dark drum]

You could have an if statement that checks if an actor is valid, and if it is then check a value from it as well. In C++ if the actor isn't valid (assuming its the first thing checked) it will fail the check without then trying to check the value from the (invalid) actor.

[wild moth]

that as well yes

in Blueprints I always have to check for validity first

[last peak]

ah so you could do

If(a > b || strlen(string) >b )

So the first option is cheaper

and strlen would never get called if a > b

[wild moth]

Your example is a bit weird but yes x)

and @dark drum makes a better example with validity which is easily done in a clean way in c++

but in blueprints you have to check for validity first

I mean it's just cleaner in c++, I can still use 2 branches in BP but yeah

I can make a macro I guess

[dark drum]

This is an example in some of my code.

[gentle urchin]

yeah manually serializing the checks is the way to go in bp

this is especially important to consider with a bunch of pure nodes with calculations in them

since every path is always executed, regardless

[wild moth]

I've been using UE for a long time and never checked these things lol like for example I know Pure nodes get executed on each pin connection but what about regular nodes

still the same?

[gentle urchin]

regular nodes cache the output

so they're only calculated when executed

today you can convert pure nodes to non-pure if you want a cached value

that came in 5.Something

[wild moth]

what do you mean? like per call?

[gentle urchin]

yes

[wild moth]

I see

Pure nodes are cleaner than non-pure though 🙉

[dark drum]

They are but there are also times you might actually need something to always be reevaluated. (like getter functions for example)

[wild moth]

absolutely yeah

[gentle urchin]

basically always consider it 🙂

[wild moth]

I just cache when I need to now tbh, if it needs it

[gentle urchin]

especially heavy calcs

two bool checks isnt whats gonna throttle you

[wild moth]

haha

very true

[dark drum]

Depends whats behind the bool. 😛 (A few get all actor of class nodes and a few distance checks)

[gentle urchin]

yes but then its the thing behind the bool check, and not the check itself 🥲

The ugliest stuff i've made is doing 6dof with directional checks

[dark drum]

Very true, but I know there are some people who would do that and then be like 'Why is checking these 2 bools tanking my frames?!?!'

I wish the height and width on the tile view widget was treated as a minimum size.

Like how am i supposed to know how big my entry widgets are going to be. 😅

[gentle urchin]

wait what

cant you just set min size ?

[dark drum]

Not that I can find. :/ Just these.

[gentle urchin]

ohhhh tilevieiw

[dark drum]

And its pretty much a hard set.

[gentle urchin]

you're using that huh

[dark drum]

I'm currently reconsidering. 😅

[gentle urchin]

unless you plan on 100's you probably dont benefit to much from it

[dark drum]

I don't want to have to handly my own widget pooling though. :/

[gentle urchin]

do you have so many that you need to ?

[dark drum]

There could be, I currently have 37 I'm testing with.

I might however just group them.

Does anyone know if Primary Data Assets created in the editor (BP) work with the asset manager?

I ask because I can't get it to work or override 'GetPrimaryAssetId'.

[white parrot]

Should work

Do you have is a blueprint class on? In the asset manager

[white parrot]

And they don’t appear in the audit I assume

Just overriding getprimaryid and forcing refresh should be enough to make them appear in the audit
Sometimes it was for some DAs but not all

[dark drum]

They don't no. I've also tried adding _C at the end as well. I'll see if I can force a refresh to see if thats the issue.

Ahh, i got it. I needed to untick 'Has Blueprint Classes' and add the _C.

Thanks for the assist.

[white parrot]

Forgot about _C
And was about to suggest turning off blueprint classes

Glad you got it though

[dark drum]

Its always the little things. 😅

On the plus side, I now know what the budle stuff is for primary data assets. Its a shame its C++ only though. :/

[maiden wadi]

No, its when you want to trigger a binded event, it's ABP dependent and not agnostic.
He explains it better in this video, in the dispatcher section on what the exact issue is.

[abstract obsidian]

Guys how you make blob shadow/drop shadow for platformer games in UE? what do you think its the best method?

[merry mirage]

If you want something that'll just kind of work, have a linetrace from your character straight down. Where it hits the ground you either

A. If you do not have a decal: Spawn a decal.
B. If you already have a decal: Move the decal to that spot.

If you want the shadow to change size depending on distance to ground you can set up a variable in your decal's material and then change that to be equal to the distance between the TraceStart and the HitLocation.

If the trace does not hit anything, hide the decal.

[merry mirage]

Hoi!

Does anyone have any cool resources on how to create a "OnActorEnteredSpline" event? I've seen some variants by creating a lot of colliders between the points, and that could work, but I want to see if there is a less clunky way out there?

I'm not afraid of using C++ if it can achieve a better result!

[left carbon]

Hello! I'm trying to make a bluetility that edits some of the assets I select. I use the GetSelectedAssets function to get the selected assets. But when I try to run the bluetility, it gets selected, and only the tool itself is included in the list of selected assets.

How do I run the bluetility with assets selected from another tab?

[abstract obsidian]

Hi! Thanks for the suggestion! Wouldnt be bad for performance to do the linetrace control each tick? Just for curiosity , I'm new on this

[merry mirage]

A single linetrace on tick is negible. If you're doing 100s or 1000s every tick I would start considering other options. But especially since you're new to this, I would say stick to what's simple and deal with optimization when it becomes an issue.

[abstract obsidian]

Perfect thank you so much!!! This boosted my confidence not going to lie , I everytime panick too much about performance

[merry mirage]

When in doubt think about the KISS principle of programming:
K - Keep
I - It
S - Simple
S - Stupid

It's easy to start worrying about performance about things that will realistically never be an issue. Fix them when they start becoming an issue, not a second before! I know some very experienced people that also needs to hear that.

[maiden wadi]

Are we talking about a flat, or relatively flat spline, like something you could place along a landscape? And you just want to know if you've entered it's X/Y area?

[merry mirage]

oui

I only care about the X/Y

[maiden wadi]

I would maybe do it with mesh creation. If you sample along the spline, and make an array of points, it's fairly easy to convert that into an extruded mesh. Then you can just do overlaps maybe. Specifics might require more of the usecase.

[merry mirage]

using the dynamic mesh component or something different? Because that sounds promising

[maiden wadi]

I used that at first. But I swapped out to ProdeduralMesh at some point. I don't recall specifics, but I had some runtime issues in cooked builds with DynamicMesh stuff.

[merry mirage]

hm, I'll check it out! Thanks a lot

[abstract obsidian]

Hey Cal I'm not understanding why my decal isnt appearing, i set my material translucent and deferred decal but when i put the component in my character it doesnt show at all

Its not code problem, its something about the blueprint itself

With the default decal image (the one that's displayed when you create the decal in the bp) it works but when i set my decals it doesnt

[merry mirage]

Might be that the decal is rotated wrong, I've had some issues where I would need to change the rotation of the.. Y-axis (?) for it to show, alternatively set the decal material to "two-sided"

[cunning vapor]

I'm trying to add an "idle animation" ive got the standard idle animation but these are random events i want to happen every once a while (IE the random integer in range -- (would be a lot higher if not testing)) How much am i overcomplicating this ?

The "sitting" animations are loops that i want to play for 2 seconds; the "standing" are one i want to play once (no loop)

Boolean checks are on tick

[gentle urchin]

I used an ISM and just mashed it along the path x)

game me the colliders I needed

along with nav modifications

for unreals pathfinding

[abstract obsidian]

this seems very weird but i did exactly as the video show: https://www.youtube.com/watch?v=MbLXOiNIIno

but i dont get my decal to show up , it stays invisible..

i dont know what i'm doing wrong , is a bug of the version i'm using? im currently on 5.1

[maiden wadi]

We do that with some other things. But for the spline volumes specifically I did them special because I needed them to match the spline's geometry. Plus ISMs will have issues with generating nav stuff if you do too much of it at once at runtime. Creates a fuckload of physics stuff, one for each ISM instance. Still fighting that because the SplineNavComponent is trash in cooked versions when it comes to runtime generation.

It's absolutely Un-fucking-real™ how much stuff in this engine is editor only and has to be cooked into a level to function.

[lofty rapids]

you want random idle stuff to happen while your idle ?

[maiden linden]

n00b here.
Where would be the best place to house variables for managing the current phase of a game that would be refrenced/changed by different actors. Level blueprint, game state?

for reference this is for a turn based game with different phases all within 1 level.

[dark drum]

The level BP is pretty much one way so you can't use that. I would say on the game state though.

[dark drum]

You can do this fairly easily in the animBP itself. I believe there's a random ani sequence node.

[abstract obsidian]

i've found my problem, my surface where the player walk is with an emissive material

so i'm trying to understand how can i poject a decal on an emissive material

[maiden linden]

Would it maybe be better to use an empty actor to store the variables keeping track of my game phases. Any insight is appreciated.

[dark drum]

I would use an 'actor component' placed on the game state.

This would make it a lot easier to get from most places.

[surreal peak]

+1 AGameState(Base) and optional UActorComponent on it if you want to keep the data a bit organized.

[faint pasture]

game state

a part of the state of the game is what turn phase it is

[lost hemlock]

is this the right way to get GUID from actor? Because I print this string and it returns me nothing...

this is how im trying to print it..

[dark drum]

The 'Actor GUID' is editor only. I don't believe anything spawned at runtime will have one and is only used for actors pre-placed in the level.

If you need a GUID, you'll need to create your own variable for it.

[lost hemlock]

all my actors are pre-placed in the level

[lost hemlock]

like this?

[dark drum]

Yes but I would use the 'Actor GUID' one instead of the instance one.

[thin panther]

That won't matter, as pattym said it is editor only. Actor GUID is not something that gets included in packaged builds. If you do find it, it's not safe to use. If you can't find that variable, it's exactly because of that reason

[cunning vapor]

Yes - for paper2d flipbooks

[lost hemlock]

but im able to generate it on Construction script for every time.. and now it works.. Will it not work on packaged build?

because im testing this on a small test project, I'll actually make a package build to test it right now, if it works on package

[merry mirage]

You can do it, I do not have experience with that issue so I cannot help you Im afraid

[abstract obsidian]

Oh dont worry

Tried to look up online but found nothing about or atleast anything that worked because the dbuffer option doesnt show up in my version of unreal

so i guess once i completed this project i can try to use that method on a non emissive materials project xD

[thin panther]

you might just get away with your method as the construction script shouldn't run in a package

[lost hemlock]

shouldn't run in a package?

so construction scripts will not execute during the package?

[lost hemlock]

also, another question, why is it dangerous?

[thin panther]

no, they will be baked in. Your variable will still be there and populated, but none of the code will run in the package, it runs once beforehand

[thin panther]

if you were to directly use such a variable in an event graph (shouldn't be possible, but can't verify directly), that would be something at runtime relying on something that doesn't exist at runtime

[distant grotto]

why would this validated get be returing not valid even though it is returning a player controller in the eatched output value ?

[next hollow]

Having a value, and being valid, are 2 different things

Connected/ similar-ish
But, not the exact same

[lost hemlock]

so that means it should work, right?

[thin panther]

Give it a shot

See if it does

[dark drum]

Just to add clarity (as I tested it myself). You can make a copy of the Actor GUID using the construction script, however, this would only work for those that were placed in the level via the editor.

The construction won't run again on pre-placed actors, only newly spawned instances at runtime. In this case, the actor GUID will be invalid.

I've used a similar method for generating GUID for world items by checking if the actor GUID is valid, if it is, I use it. If not, I generate a random one. (Used for saved data) I've also tested in a build and would as you'd expect.

[distant grotto]

hmm the only time i set it is at begin pplay and im not doing anything to the player controller

[next hollow]

Would need more context, but hard to directly say.
You aren't doing a valid check on the get controller
(I recently myself found out that casts don't do valid checks, simply just null value checks.)

and, begin play is a bad place for get controller, cuz its actor creation.
Doesn't mean the player is controlling it yet, or etc.

[distant grotto]

I also do it on event possessed i just noticed

[next hollow]

Yeah, its hard to say, without much context.
Are you logging out a player, or re-connecting, or what.
Cuz, such an action would cause the "issue" your running into, possible.

[distant grotto]

no nothing like that which is why i have no idea how to figure this out

the error i get is accessed none, even though i see a value in debug view

[next hollow]

Yeah, its like I said.
The value is marked for destruction (not replicated, destroyed, or by direct choice, or etc)
Hard to see why/ what is causing it in this exact instance.
Try to print string end play on the PC graph, see if it fires, and if theres a reason perhaps

[distant grotto]

thing is, the player controller variable is valid in other places on the same blueprint

is it because im using an interface message wrong maybe?

[next hollow]

Oh, wait...

Its obvious now. lmao

At the exact time of running its invalid.
But, the value might become valid like a half second later.
Break point the validated get, or/ and the print string node.

Or, just print string the value. 😛
(this is why I kinda hate the BP debugger.)
Can just peer into shit at any time.
So, while your watching the validated get, your actually watching that entire variable, so if its set like 0.1 seconds later...

[distant grotto]

pc decided to restart for whatever reasn lol

but yeah it is returning empty when i print the validated get

but the same variable works in the sprint function at the same time

[next hollow]

So, yeah.
At the time of whatever that it, it is in fact no value.
But, some half second, 0.1 seconds later it gets set

Such as.
If this is on tick.
For like 10 ticks, there is no player controller.
But, after 10 ticks or whatever amount of time.
The character gets possessed, and thus has a valid controller ref.

Hence why this is invalid, but sprint is not, cuz its after whatever amount of time.

[distant grotto]

that doesnt really make sense in my case though. It fails when the player character overlaps with an interactable object collision, which triggers an event in the character bp via interface. i cant see any reason why it would be cleared only on the exact frame that the player overlaps with a collision

[next hollow]

Are you spawning next to an interactable object?
Thus, it would make sense.

Or, is this a constant issue, whenever trying to use one of your interacts, even if you've been loaded in for a bit?

[distant grotto]

ok maybe its not the player character reference, the error message might have been wrong. i replaced it with a cast and now its saying that it cant get something from the player character, which makes more sense

[distant grotto]

constant issue, not spawing in a collision

[distant grotto]

although it shouldnt have been printing none for the validated get anyway so idk

well this fixes it even though its a terrible way to do it

[next hollow]

I think that indirectly fixes it, cuz the 2nd cast, acts as a valid check, cuz the error you get is it being a null/ none'

[distant grotto]

youre right, it just wasnt executing the sync node 🤣

[gentle urchin]

This is some setup

Why the interface at all at this point

Not like you've avoided coupling

[brittle garden]

Hello, I'm working on an FPS but I'm having a problem with my projectiles. When my character moves, the shots seem to be fired differently from the player, which makes aiming difficult. I can't seem to fix the problem. My projectiles are Actors that I spawn.

[crimson briar]

What do you mean "differently"? What would you want to happen with the bullets?

[brittle garden]

I'd like my projectiles to be "straight" when fired, like in an FPS game where bullets always fly straight. I don't know if I'm being clear, sorry, this is my first Unreal Engine project and I'm a beginner.

I wondered if I could fix the problem with a Trace Line and a particle effect for the shot, but I don't know how to set it up.

[crimson briar]

They do fire straight though. You are just moving

They appear like they are not straight due to the speed of the projectile relative to the speed of your character. In most games projectiles are almost instantaneous so there is no time for the character to move between them spawning and disappearing

[brittle garden]

Okay, very good, thank you, that's clear. I wasn't 100% sure about my projectile.

[crimson briar]

You can always test it by addind a debug draw sphere on the projectile tick for like 5 seconds. Then in PIE detach, pause and look at the trajectory from a different angle

[sick sky]

@subtle hare ask here

[subtle hare]

i will

just not right now

[sick sky]

usually you spawn a projectile on the pawn on input, the projectile would be a new actor you spawn

[subtle hare]

yeah i know that i just dont understand how to make the projectile travel in a straight line

[sick sky]

constant linear velocity

manually or using the projectile component and a sphere component at the root

[last peak]

If you want a hitscan you dont need a projectile at all

A linetrace is enough

[spiral meadow]

Hey Guys, i am fixing some bugs and i got one from flashlight in hand socket, anybody know how to fix this i am stuck here for a long and thus doing other things too but didn't get this one

[maiden wadi]

You never told it to unequip whatever is already there.

[spiral meadow]

Okay, i will do the unequip one and can u tell me what's the problem with the movement after equipping the flashlight or any equipment in hand socket

[maiden wadi]

I'm not sure what the movement issue is? If it's stopping you from moving in a direction, then chances are it's collision. I'd probably disable collision on the spawned actor before attaching it.

[gentle urchin]

Does it ever make sense for an actor to collide with an attached actor ? Perhaps something like shield surfing but other than that? Even then its probably easiest solve in another way ..

[north bobcat]

anyone know why my colours arent matching up?

[maiden wadi]

Not without more info. What are the zero? Textblock?

Are they tinted? In a border that tints child widgets? Using a material that affects color?

[pulsar monolith]

if you're using a Text Render Component, try this method

[tropic torrent]

In terms of optimization I have a question.

I have created a 'dash' function, when it is triggered the actor will have an increase in movement speed, immediately be launched, and be intangible for the moment.

[north bobcat]

it is in a border

[north bobcat]

nah its ui

its a widget

[tropic torrent]

If I make a bunch of dash abilities, would it be better to copy this function into each of them, and only have them be referenced when selected
Or
Leave the base dash in the player character, have the input come from outside and the output go to outside?

[maiden wadi]

Check the tints on the textblock and the border. Make sure they're both pure white.

[tropic torrent]

if they choose "ice" for their dash they'll have invincibility + might freeze an enemy or smthn

[pulsar monolith]

for example, when you change orange to blue, what happens?

maybe it's about sRGB convertion

orange turns to red

[north bobcat]

nah it aint that

the border colour tint is white

its the text with a bind

[crimson briar]

For optimization it doesn't matter that much, it is more about ease of use and expanding.
You could make an actor compontn Dash. Then add it to your character and call the dash function from it whenever you want.
Then you can inherit from the Dash and make Dash_Ice component. So when the character has the ice dash, you remove the normal one and add Ice one.
As to designing the dashes - you can have multiple events on the Dash component. Like "OnDashStart" "OnDashEnd" "OnEnemyHit" - they don't even have to have code at first. The main function for dasahing uses them and triggers related events when needed.
But what are they for? For the children ofc. The Ice Dash could overwrite an event or several of them to include some additional behavior in the normal dash.

At least this is how I would attempt something like this

[maiden wadi]

What happens if you pass back the color in that binding without the property? Like hard coded?

[north bobcat]

what

im in the slackers vc if you wanna join I could show you

[maiden wadi]

In this. If you disconnect Orange, and hard code it.

[north bobcat]

that aint the issue I think its the border

because the border being white changed it to red

[tropic torrent]

ahh, I still need to learn actor components better, thank you
You think that'd be better for performance too? Trying to make the game light weight if I can

Also, if doing it like that, how do I make the ice dash overwrite the event?

[north bobcat]

wait I fixed the colouring thanks

[crimson briar]

Code weight is negligible. Until you add models, audio or textures etc - everything else tends to be very small, especially a component or an actor without any meshes

[tropic torrent]

damn okay lol

I was also told the main significant thing in code weight is whether or not it is referenced by player or gamemode

[storm stream]

Anyone know how changing values in Data Asset will perform in packaged project? It need to be saved (savegame) and always read default values or everytime if i start build values will be changed like in runtime?

[tropic torrent]

seems like that's the only thing that really matters

I'll tryyy to get the art team to keep it light weight then

[crimson briar]

If you want to know what is the weight of an asset, you can right click an asset in the asset browser and open the size map. There is also a reference viewer to see what is loaded with this asset

[maiden wadi]

Not 100% following this question. Are you asking if you need to save a data asset's values in a savegame between game sessions?

[pulsar monolith]

how you fix it?

[storm stream]

Im asking if i need to do so in packaged project, or it will reset to default values or works like in runtime (its saved in data asset)

[maiden wadi]

The data asset will reset to default when it's loaded. This may happen when you start the game, or when you let it be unloaded by losing references to it and then reload it some time later.

So if you need it's changes saved, yes you'll need a savegame. Though you may also be able to make them Config properties. That may or may not work to save them to and read them from an INI file. I've never tried that with a static asset though.

[north bobcat]

anyone know why this is highlighted red?

[storm stream]

So its not work like in runtime, i need to save all modified item data and load it on game start again?

[maiden wadi]

It works like any other class. When loaded, it has it's default properties you've set in editor. If you change those in the middle of the game and want that to persist they need to be stored in a savegame or ini and reloaded later.

[storm stream]

Of couse, its has default properties i set in editor, but if we talk about Data Asset, its can be changed and its saves itself in data asset in runtime, so i was wondering if it happens in packaged project too

[dusky hemlock]

I'd like to add some things to what VaraelHasta wrote.

First of all, I'd like to throw in GAS (Gameplay Ability System) which is made specifically for what you described what you want to do, the main benefit is that you don't have to work with multiple components, creating objects and destroying them when they are done or changed. You can create Effects which lets an enemy be stunned or gain invulnerability for example.

Second of all the size map likes to "lie" because some things will always be loaded in the context of the object, like the main player character for example. So if you have an objects that is referencing the player, the player and all it's references will be shown in the size map, meaning you often don't really see the actual size of the object you are looking at

[storm stream]

So for be 100 % sure, its doesnt, yes?

[maiden wadi]

If by runtime, you mean PIE, then no. The issue is that PIE is still editor. You can edit things from PIE accidentally and then save them unintentionally.

DataAssets are normally static data containers not meant to be altered at runtime. You can't save them in packaged no.

[north bobcat]

??

[crimson briar]

I should have clarified to look at the SELF in the size map, my bad.

[storm stream]

I want to make upgrades on items, and one of the idea is to change value in data asset and then save it on savegame but i think it will not work if data cant be altered

[maiden wadi]

This is usually handled by a runtime instance. Or some sort of multiplier. For example if you have items with a price, but one player gets a 25% discount, then that would be more like a BarterCostModifier related to the player set to 0.75. The static price in the data asset stays at whatever it was originall. Say 50. But when you 'buy' the item, or show it in UI, you multiply it by that player's BarterCostMultiplier. So you get OriginalCost*BarterCostMultiplier=BuyValue

Alternatively if you're trying to alter the 'original price' of one instance of the item you wouldn't do to that on a data asset but it's runtime data container which should be a UObject or a struct.

The data asset remains static and never altered.

You save the player's stats like BarterCostMultiplier and the items in the game so that the runtime state can be reloaded.

[north bobcat]

why

[storm stream]

It will works too, but i using DataAsset as my pickup item, and upgrades works "globally", so if i updated item i want all kind of that item have altered values, of course i can copy-paste code to whatever bp i need, but its messy

so i was looking for someting better

I can also duplicate x times my item and then changes values to what i need, its also some type of solution xd

well i can also create some sort of macro/function in 1 place and then calling it whetever i need xd

ye, that will do

[maiden wadi]

The issue with relying on the data assets for your data like that is that if you ever decide to need that data per person. An AI player, a second in game player, whatever. Suddenly you cannot change the data asset. Right now you're backing yourself into a design corner by altering what should be unchanging static data.

[storm stream]

i was thinking about creating a copy(instance?) of that item and using it as my free-to-change object

but idk if it possible

[maiden wadi]

Could work. But I would strongly recommend just doing a struct or uobject with the changed runtime data. Even if you store the data asset in it for lookup for static data.

You get better clarity of who owns that item because that data has to live somewhere related to the player. Like a component on their pawn or playerstate. Data Assets exist kind of globally and that causes confusion about ownership.

I'm also semi sure that you'll have replication problems if you ever went multiplayer. As the asset wouldn't have an actor as an outer like a normal UObject.

[storm stream]

Its singleplayer, and its only inventory for main character

or not exacly, i also have it in some containers that need to be altered too

well, i need think about it more

[frigid quartz]

Hey guys, is there some node like select, but for execution pins? I want a node to which I can wire multiple execution pins and select value based on which execution connection was executed

[tropic torrent]

Okay I'm making my very first bluepint component, would anyone like to help me :3

I copied and pasted my dash function, but now all the references are broken 🙁

I'm just reinputting the objects, making it start with a custom event with an input "Dasher" that referenced BP Combat Character

[frigid quartz]

So I basically want something like this, but generic:

[sand shore]

Arrays can be kind of tricky, but if you add/remove an element from that array, then it should work ok.

If you need to change an existing element, you still need set array element or to specifically use “get (by ref)”

[knotty scarab]

thats not what im doing

[sand shore]

Ah so you’re wanting to use it from a different exec wire path, one that never calls that set node?

[knotty scarab]

Im just asking if its needed for me to place a seperate GET node to retrieve that array, instead of using the output of the un-executed SET

ie the old value

[sand shore]

The output of the set node is actually a Variable_Get and it always gets the current value of that variable

[knotty scarab]

good to know

[sand shore]

Unlike other nodes, that output pin isn’t stale

[knotty scarab]

thanks

[tropic torrent]

Chat I'm so lost lmao

I got desperate and used get all actors of a class 🙁

[unique bronze]

Hello, I cannot figure out how to invert this to start thick from origin and become smaller.
Really appreciate any help with this headache 😅

[tropic torrent]

okay figured it out, had to add it to the character! ^-^

wait can I chain BPCs to each other or do I need to use cast to

[lost hemlock]

Hi I have an issue with this... Im trying to save & load the sun transform direction

The problem is... this event dispatcher doesn't work...

but it doesn't make sense, because im always doing event dispatchers and they all work

[lost hemlock]

It doesn't need a target, it never needed a target before so I assume it's not gonna need target now, and I can prove it

this is how im doing my sleep... So this event dispatcher works

[crimson briar]

Do you have a return node inside the loop above the dispatcher call?

[lost hemlock]

in which dispatcher call?

these are the 2 that aren't working

I just made them

[lost hemlock]

what do you mean?

[crimson briar]

Maybe let's start with something else - by the dispatcher not working, do you mean it is not being called, or is the bound event not activating?

[lost hemlock]

both

same thing

[crimson briar]

Well, no, it is not the same. One is a problem with the binding, the other with the way you call it

I see you call the SetNewSunDireciton dispatcher inside a function, and it is on completed pin. A common mistake in situations like this is using a Return Node inside the loop itself

Which causes completed pin to be ignored

[lost hemlock]

so both of the binds get activated, but they never get called once they're activated

[crimson briar]

And this works?

[lost hemlock]

Yes ✅

[north bobcat]

why is this red??

it isnt in anything

like its not in a border or anything

[lost hemlock]

https://tenor.com/view/tired-beat-exhausted-tcm-headache-gif-26366550

@crimson briar event dispatchers are very confusing

[north bobcat]

so is this

😭

[crimson briar]

I'm assuming it is a Level Blueprint. Are you sure it is binding to the correct character?
It can be tested by printing the display name of the character here and in the character itself to compare

[lost hemlock]

I only have 1 Char

[faint pasture]

those redirect nodes are a smell

[lost hemlock]

But I have other interfaces in that same level_blueprint that work fine, and communicate to exactly the same character

[faint pasture]

what the fuck

burn it

[knotty scarab]

no

[faint pasture]

You can just put another getter, it's literally the same

[crimson briar]

Bro is building a racing track inside his blueprint

[faint pasture]

It's more readable with literally the exact same code

[knotty scarab]

?

for what image 🙏

im getting confused

[faint pasture]

They are literally the same

except one is readable and one is not

[knotty scarab]

okay but im using local vars

[faint pasture]

you always gotta keep the pins that shoot off out of view in mind

[knotty scarab]

inside a macro

[faint pasture]

same thing

[knotty scarab]

?

its not gonna be the same variable

[faint pasture]

is it a local variable or a macro input?

a macro is just copy paste

a function has its own scope and can have a local

[knotty scarab]

something like this wouldnt work

[faint pasture]

swap min and max scale

[faint pasture]

Sure but if you're making big code like that you're really barking up the wrong tree

[knotty scarab]

ill do anything to squeeze out a few bytes of disk space

[faint pasture]

all your bytes are spent on textures and audio, BP logic is approximately zero

[knotty scarab]

textures are for nerds

BPs all the way

DownloadImage for all the textures

thats the method

[faint pasture]

You may not like it, but this is what peak BP looks like lol

[knotty scarab]

meh

one straight execution line

talking about sins...

.>

[faint pasture]

it does what it says on the tin

at a glance you can tell that's a special case

then you can zoom in on any executable and see all the data it eats right there

This is a tire model so it represents a lot of number crunching, most of my stuff isn't this crazy

[tropic torrent]

I made a custom event and

[tropic torrent]

BRO

[knotty scarab]

as long as it works

[tropic torrent]

I made A custom event but I have a question about the object coming out of it

[faint pasture]

Hell no, whoever made this is fired, yesterday.

[faint pasture]

hit it

[tropic torrent]

When I call the custom event, I can obviously put an object in the input

But from the custom event, the red one, I have to set a specific object

[knotty scarab]

promoted to lead developer*

[faint pasture]

show code

[tropic torrent]

Is there any way I can make it so I don't have to set a specific objectm

[faint pasture]

and remember these are object references (pointers really but whatever)

[tropic torrent]

Dasher references BP_Character

[faint pasture]

is Self a BP_Character?

win shift S btw

[tropic torrent]

what I'd like to do is make it so self can be any 'self'

[tropic torrent]

School computer no discord

Using the lab

[faint pasture]

What actor has the N input?

[tropic torrent]

Better computers than at home

it works with the player

that works

but I want to make the custom event not be player only, if it's possible

[faint pasture]

What is the type of Dasher?

[tropic torrent]

so when I drag in self on the enemy, The custom event can have the enemy dash

[tropic torrent]

BP_Combat_Character?

[faint pasture]

and is enemy a subclass of that?

it should be

[tropic torrent]

Enemy is it's own blueprint I think

I'm using the combat preset

[faint pasture]

k so that's the problem

[tropic torrent]

If this is possible it means I don't have to make a new dash BPC for every type of thing that dashes

[faint pasture]

You probably want this sort of class heirarchy:

Actor
Pawn
Character
YourGameBaseCharacter
PlayerChar
Enemy

you should put the bulk of your code in YourGameBaseCharacter so PlayerChar and Enemy both share it

fundamentally the only difference between PlayerChar and Enemy can be as simple as material or mesh, they can otherwise literally be the exact same thing

[tropic torrent]

bp_combatcharacter and Bp_combat enemy are both characters

[faint pasture]

they need to both be BP_YourGameCharacter

[tropic torrent]

Is there a built in pawn or would I have to make one?

[faint pasture]

whichever one has the most work in it, make that the new base, and extend it to Player and Enemy varieties if you want

[tropic torrent]

there should be one, no?

[tropic torrent]

would they be child blueprint classes or something else?

[faint pasture]

Here's what you have:
Character (provided by Unreal Enginer)
BP_CombatCharacter
BP_CombatEnemy

Here's what you want:
Character (provided by Unreal Enginer)
BP_YourBaseCharacter (put most if not all of your custom code and variables here)
BP_CombatCharacter (changes can be as simple as different defaults and mesh etc)
BP_CombatEnemy (changes can be as simple as different defaults and mesh etc)

[tropic torrent]

okie, what would the BP character/enemy be? Children?

[faint pasture]

yes, child classes or subclasses

[tropic torrent]

are those the same thing

[faint pasture]

just like how their parent right now is Character, their parent should be BP_YourGameBaseCharacter

yes

[tropic torrent]

AH In class settings

[faint pasture]

I would recommend just turning one of your classes into the parent one and reparenting the other

[tropic torrent]

yeah I see where to change it

[faint pasture]

I'm assuming you haev most of your stuff in BP_CombatCharacter, just make that the base

the subclasses can basically be data changes only if you set it up right. Set up your character to not care at all if it's being driven by a PlayerController or an AIController

as a bonus, you'll be able to play as any character in the game and also have ai drive any character in the game, if your game is something where that'd be useful

[tropic torrent]

that's pretty cool

[faint pasture]

The only difference between Master Chief and a Grunt is that the grunt has different stats and a different mesh and animations. Fundamentally they all have the same core

[unique bronze]

hey thanks for your help, if I do that, then this happens

[tropic torrent]

Wow

Parent would have no mesh, right?

[faint pasture]

Is this all you did?

[tropic torrent]

anything that both player and enemy can do should be in the parent, and player/enemy specific things should be in the children

[faint pasture]

nah it'd have one

[tropic torrent]

it'd still be replaced?

[faint pasture]

could just be a T posing default mesh or whatever but it has one, Character has one so you can't not have one

[unique bronze]

yup

[faint pasture]

this is a spline + spline mesh components right?

[faint pasture]

show more of the code

[faint pasture]

CMC and mesh etc come from Character, the stuff that'd come from YourBaseClass is the stuff you added like bDashOnCooldown

also you'd put your dash component in YourBase etc

the final subclasses could have literally zero additional code if they aren't meant to have unshared functionality

[jovial bramble]

Hello, can someone tell me how to deactivate the option so my character doesn't get it's speed to 0 when he looks down or up please.
thanks

[faint pasture]

show how you're adding movement input

I'm guessing you're adding it in the control rotation or camera direction

so when you look down you're telling it to move down mostly, which it obviously can't do, so the x and y components of the direction you're telling it to move in are smaller

[tropic torrent]

So for example, let's say enemies only move and attack, those two would be in the parent (Base class)

Then in the player I have input, while on the enemy I have AI?

[faint pasture]

What can the players body do that the AI's can't?

you can put input in the base, AI just won't call it

[tropic torrent]

Move their camera and let's just say jump for the love of the game

[faint pasture]

I'd just put everything in base for now

[tropic torrent]

more for understanding

kk

what stuff would you put in player/enemy only?

[faint pasture]

Player presses mouse button -> call Attack
AI just directly calls Attack

[faint pasture]

Stuff that's meant to be exclusive to them, not much tbh. I prefer it to be nothing

I really like systemic games though so all my stuff has the player's pawn be nothing special, it's just a pawn that the player is driving around

[jovial bramble]

okay

[faint pasture]

if you break control rotation, then make a rotation using just its yaw, and get that rotations forward and right vector, that'll do it.

basically removing pitch from the equation. That'll work for the usual 1PP/3PP control scheme

[tropic torrent]

so let's say I want to add a select spells system, player has at most 4 spells

[faint pasture]

can AI have spells?

[jovial bramble]

i see now, thank you

[unique bronze]

yup its a 2m long segment on a spline component

[faint pasture]

Or rather, are spells something special or could you consider BasicAttack a shitty spell

[tropic torrent]

set spells yeah

[jovial bramble]

so i jsut use X and not y, but do i have to add something esle ?

[faint pasture]

I'd probably reformulate the math to cook up the scale based on total time along spline instead of the integer math stuff

[tropic torrent]

yes

basic attack is a shitty spell

[faint pasture]

That's the way I like to formulate it but it all depends on how crazy and generic you're trying to go

[unique bronze]

so not use Get Number Of Spline Points? What would you suggest? Get Scale At Spline Point?

I have to take the end scale of each segment as a start scale for next one though

[faint pasture]

Scale = Lerp(MaxScale, MinScale, Distance / TotalDistance)

[unique bronze]

Alright, Ill try that, tyvm!

[faint pasture]

just make sure that alpha value goes 0-1 or 1-0 along the spline end to end

[unique bronze]

Just clamping would suffice?

[tropic torrent]

Wizard of Legend is my inspiration for this project so ye, basics are spells

[faint pasture]

when you're setting the data up for one end of the spline mesh component, assuming you have a correct Distance and know TotalLengthOfSpline, just use that ratio as the input to your lerp to cook up the scale

You're cooking up a distance here, so assuming that's correct then you can use it for cooking up the scale

[tropic torrent]

could you show me how I'd do a set spell system? I don't plan on making the spells or limited slots for now, just curious how it'd be in the parent but different per child

[faint pasture]

It can be as simple as just having 4 events in Parent which are overridden in children to do the thing, assuming 4 is the max anything would have

or you could have an array of MySpells which are actors

or they can be components

or use GAS

[tropic torrent]

How would you do it? Actors seems to make sense

[faint pasture]

just make an actor Ability which has events StartAbility and StopAbility

maybe it has a reference MyCharacter so it knows which character owns it

begin play of Character -> spawn the spells and save refs to them in MyAbilitiesArray or MyAttack and MySpell1 etc

You'd subclass Ability per spell type so you'd have BP_Ability_Fireball and BP_Ability_BasicAttack

ability can hold stats like its damage or whatever, and hold which anim montages to play on MyCharacter

Say you made Jump an ability

BP_Ability_Jump

Event StartAbility -> call MyCharacter.Jump
Event StopAbility -> do nothing?

BP_Ability_Fireball

Event StartAbility -> play some looping montage on MyCharacter -> play timeline charging up some float Power
Event StopAbility -> Spawn a projectile at MyCharacter.WandTip in MyCharacter.ControlRotation direction, give it damage based on Power

[tropic torrent]

you lost me here

[tropic torrent]

I understand this

[tropic torrent]

I understand this

[tropic torrent]

?

I guess I don't know how to do arrays yet, much less save refs

[faint pasture]

drag off Return Value and name it MyAbility

then you can talk to it later like when you press inputs

[tropic torrent]

make it a variable?

[faint pasture]

although this might be a bit much if you're brand new

[tropic torrent]

Nah it's good

Oh it sets an object

That's pretty cool

Do I want this to be an array?

[faint pasture]

not now

get 1 ability to work

then worry about having an array of them

MyAbility , then worry about MyAbilities (plural)

You can even not worry about using an array at all, just have MyBasicAttack, MySpell1, MySpell2, etc

[tropic torrent]

Hmm

can you explain the SpawnActor node? how is it doing the spells?

[faint pasture]

M1 pressed -> call MyBasicAttack.StartAbility
M1 released -> call MyBasicAttack.StopAbility
etc etc

[faint pasture]

it's just spawning an actor

your abilities ARE actors

they could be components, but I prefer actors since an actor can have timelines which are great for ability stuff

[tropic torrent]

how does it know which one to spawn if I have the children

[faint pasture]

Class can be a variable

so you can set what class MyBasicAttack should be in subclasses of BaseCharacter

[faint pasture]

but this code would be the same

the only difference between EnemyA and EnemyB could be which class they have for their basic attack

[tropic torrent]

ahhh, so drag out left from Class

says I need a transform

[tropic torrent]

I 100% get it

[faint pasture]

make sure the variable type of MyBasicAttackClass is BP_BaseAbility class reference (purple)

so only subclasses of BP_BaseAbility can go in it

you don't want your basic attack to be a landscape or a skybox

[tropic torrent]

ye let's do the jump for now

[tropic torrent]

👍

hmm

need the transform loll

[faint pasture]

just give it any old transform

where the ability is doesn't matter

[tropic torrent]

how xd

variable with nothing set?

[faint pasture]

make transform

[tropic torrent]

hmm

now I have this error:

Blueprint Runtime Error: "Accessed None trying to read (real) property Ability1 in BP_CharacterTest_C". Node: StartAbility Graph: EventGraph Function: Execute Ubergraph BP Character Test Blueprint: BP_CharacterTest

AM I SETTING THIS IN THE WRONG PLACE

I am

The PlayerCharacter has to set the Ability 1

And the execution of ability 1 is done in Parent

[faint pasture]

you might be overrideing BeginPlay in PlayerCharacter without adding a call to the parent classes BeginPlay

just add a parent call

[tropic torrent]

how?

[faint pasture]

right click the node you'll find it

[autumn pulsar]

Does the Uobject class have that much overhead?

[faint pasture]

or just delete the node if PlayerCharacter.BeginPlay isn't doing anything

[faint pasture]

relative to what?

[autumn pulsar]

I'm wanting to make something mimicking a traditional C++ class

[faint pasture]

it has an amount of overhead

What are you actually trying to do

[pulsar geode]

anyone know how to have an actor (A) tilt to face another actor (B)?
i have A always facing north, but i want A to tilt itself 30 degrees towards B on a button press without A changing to not face north. essentially no matter where B is, at an input A will tilt towards it.

[autumn pulsar]

A "Stat" struct with functions like "set max" or "set value"

[faint pasture]

make it a struct

[tropic torrent]

cast to?

[autumn pulsar]

I guess it'd be somewhat cleaner to just directly access the variables

[tropic torrent]

on the child or parent

[faint pasture]

AFAIK you don't get access to struct member functions in BP

in C++ you can do it

[tropic torrent]

damn auto suggest 💀

[autumn pulsar]

Yeah which was why I was asking about UObject

[faint pasture]

show your current PlayerCharacter.BeginPlay

[tropic torrent]

tyvm this definitely will change how I do things

[tropic torrent]

It was this

added the make transform

[faint pasture]

I prefer structs if it's meant to just be a data container with no lifetimes etc

[tropic torrent]

but then I disconnected it and did this

In the child

[faint pasture]

the child class shouldn't have to do anything rn

[faint pasture]

just do this all in parent class

[tropic torrent]

I'll make it the copy in a moment, just wanted to look through enemy and player to see who has more work

[tropic torrent]

I did and it wasn't working 🙁

[tropic torrent]

this error

[faint pasture]

right click this, add call to parent

so it sets up the ability for you then proceeds with whatever the child class begin play does

[tropic torrent]

then connect it to that?

[faint pasture]

Parent:
BeginPlay -> set up ability

Child:
Begin play -> call parent begin play -> do whatever else Child has to do

[tropic torrent]

👍

Imma remove the set

[faint pasture]

now lose all the abiltiy stuff here

[tropic torrent]

put it back into the parent

[faint pasture]

this is where you'd do setup stuff that's SPECIFIC to CombatCharacter, in addition to whatever BaseCharacter does

shouldn't be much

preferably nothing

[tropic torrent]

error is back

[faint pasture]

show base class begin play

[tropic torrent]

Blueprint Runtime Error: "Accessed None trying to read (real) property Ability1 in BP_CharacterTest_C". Node: StartAbility Graph: EventGraph Function: Execute Ubergraph BP Character Test Blueprint: BP_CharacterTest

same for StopAbility

[autumn pulsar]

if you do alt+printscreen you can take a picture of the current window and then paste into chat

[tropic torrent]

basically 2 errors per

[tropic torrent]

I know, I'm on school computers

[faint pasture]

show this again

[tropic torrent]

It's still that, nothing changed

I removed the set tho

[faint pasture]

delete anything to do with abilities there

[tropic torrent]

ye did it

just disconnected the execute line

[faint pasture]

you sure you compiled?

nothing in the child class should mention abilities at all in any way shape or form

the only ability change you should make in child classes is what the default for your ability classes is

[tropic torrent]

yes

[tropic torrent]

that's the problem lol

[faint pasture]

not changing the class on begin play, just setting the default. You need to show inherited variables

[tropic torrent]

it's just event begin play -> parent begin play

[faint pasture]

do you have input events here that talk to abilities or are they gone too?

[tropic torrent]

Gone

Everything gone, it's just those 2

The sequence is just 'set hp bar' which I'm moving into parent class after this

the default hp bar from combat

[faint pasture]

show the default value of the class

the ability class

[tropic torrent]

None

[faint pasture]

that there's ya problem

[tropic torrent]

(no default value)

[faint pasture]

you're spawning nothing

pick an ability

[tropic torrent]

isn't it setting the ability

[faint pasture]

you're saying it has no ability

give it one

just pick one from the dropdown

[tropic torrent]

"Editing this value in a class default object is not allowed"

or do you mean the purple one

[faint pasture]

purple one

[tropic torrent]

Oh

Yeah that'd do it

[faint pasture]

purple one is the class thats used to spawn the actor

[tropic torrent]

So on the children I'd set purple

[faint pasture]

purple is class, blue is object

[tropic torrent]

equivalent to name and action, ic

indeed works now

do I need a different purple for each child

[faint pasture]

do you want them to have different abilities?

[tropic torrent]

yes

[faint pasture]

you can set the default in the parent class and just change it in children

so everyone gets BasicAttack unless changed

[tropic torrent]

fire enemies have fireball, ice have ice shard

you get the point

A set?

[faint pasture]

whatever you set in parent class is the default

children can change it

jjust like how children can change teh max run speed in their CMC

[tropic torrent]

so they all can use the variable

[faint pasture]

or the mesh

yes

[tropic torrent]

don't need 100

that's awesome

Thank you, I really wanted to make something like this to make this much easier

Imma send one last screenshot then make everything the parent

This would be the drop down, right?

[faint pasture]

nope

[tropic torrent]

oop

[faint pasture]

set it in the actual variable

on the left

gotta show inherited variables

[tropic torrent]

In details

oh?

where are inherited variables

don't see em

in the case of a player where they can select abilities, would I use a set then?

<@&213101288538374145> seems sus

[tropic torrent]

okay I know now but you could've zoomed out a little XD

[pulsar geode]

anyone know how to have an actor (A) tilt to face another actor (B) without losing it's current direction?
i have A always facing north, but i want A to tilt itself 30 degrees towards B on a button press without A changing to not face north.
currently I can find the correct angle needed to have a debug arrow originating at A point correctly point to B's position (represented as the red axis) but am having trouble getting RotateVectorAroundAxis to use the y axis (represented as the green axis) to rotate it 30 degrees

[queen beacon]

Hello, I need help, I am making shader by tutorial and I don't know how to make this. Can someone help ?

[faint pasture]

how does something change its rotation without changing its rotation?

show what actor A's rotation should be in these situations
