blueprint

[atomic salmon]

They can all be instances of the same BP each one assigned to a different "key" but yes

[narrow sentinel]

and I put this derived component within my ship actor where I need them

[willow gate]

Thanks. I'll try that

[narrow sentinel]

the way I have to do the attachment of it all is attach to component as it's not happy when I do it through construction etc

[haughty ember]

I'm spawning an actor (Fireball) and it seems to hit the instigator. I'm using Ignore Actor when Moving node, in both directions, and I made sure it happens before the hit event. What am I missing?

[fervent crypt]

@frosty heron Ok so in editor when I hit play runs as it should
Title screen>
Main menu >
Play> [play is where the new map loads and where the sequence is and does plays like it suppose to and the game starts]

In PiE is the same

But when I package it and try to run it in android and won't play.

When package on android

[restive raven]

Hello everyone 🙂
I have troubles with this blueprint. I want to disable the camera cut inside a sequence if I don't have a VR headset on. It runs as intended in editor and with the "laucnh game" option, but not inside a packaged version (from dev to ship). We tried to activate it even without the branch, and it doesn't work. The SQ cut returns its correct name in ship, but the camera cut still isn't disabled
Any ideas ?

[tight pollen]

is there a way to use projectile movement with physics so that the item normally reacts naturally to impacts rather than being stiff

it is always in one position when I turn on bouncing

does not rotate etc

[rare gale]

Is there a way to make the editor stop collapsing menus when editing inside of a component? I have a setup structure with structures inside it and just filling in an INT field collapses all menus and I have to reopen each one every damn time making it nearly unusable

[pulsar osprey]

you could just disable the projectile movement component on collision and turn on physics simulation

[faint pasture]

No, you could just have the tracer tell the Hit Actor "Hey I just hit you, and I hit this component" and let it sort it out from there

You'd want that to be an interface call most likely

Then each key could be a primitive component or bone within a skelmesh and the keypad can sort out which key component maps to what data like number entered etc

[willow gate]

I already set it up with separate instanced actors for each key. It's pretty clean that way since I can set up my functionality from the key actor class.

[faint pasture]

How do you make a keypad? Child Actor Component per key?

[willow gate]

Yeah. The Keypad actor BP has a mesh for the keypad housing. Then each key is a child actor component with a hit collider which captures interaction traces through and interface and dispatches an event. The actors that the keypad can activate are listening for that dispatched event

The values of the keypresses are manipulated by the server and OnRepNotify gives dispatches another event which the keypad widget is listening for, so that the digital display can display what the player has pressed and everyone can see it.

[faint pasture]

Networking and ChildActorComponent is a fun time

[tidal marlin]

This is the first time I've heard about this bug, or I don't understand what it's about. There was a similar problem with editing Default parameters from variable settings. In this case, the advice was not to edit Default from the variable settings, but use the class field.

[tidal marlin]

Yes. It's very funny.

...

[willow gate]

It seems to be working fine the way I have it set up because when the player interacts with it, it sends a reference to itself and then I call a server RPC from the interacting player.

[tidal marlin]

I do not know about replication in the current build, but in 5.1 it worked terribly, especially with complex structures. For example, Character Child Actor and other things.

[willow gate]

I'll expect problems then but so far my testing has show working results. There's nothing very fancy happening so maybe that's why

[tidal marlin]

You can remove the Projectile Movement and enable normal physics as an option.

[rare gale]

If I hit the plus on the last array "Objectives", it'll add the new index, but close up everything up to the root level. I have to reopen eadch layer to get back to what I just added and if I want to add a bunch, it's horrible. I noticed it's even worse if you use the Property Matrix. Even entering an Int in a field that already exists will close everything. I thought maybe it had to do with construction scripts trying to run (I'm not using any), but turning off that generation didn't seem to help.

[broken bay]

hi all, I am doing some synthetic video data generation. I am thinking to add a functionality to easily add more cameras pointing at an object of interest.
For example, I want to record an actor, then I can just click the actor in the editor, and maybe a button on the details panel can add a camera (specifying the direction and distance from the actor) to be spawned in the level.
How would I go about doing that? Just BP on the Actor? Or do I need something like Editor Utility?
Thanks!

[tidal marlin]

Unreal Version?

[rare gale]

5.5 currently, but I've seen this at least back to 5.3.

[tidal marlin]

Using Construction script?

[lunar sleet]

kinda looks like you're trying to use an Array instead of GameplayTags or...structs or something

[rare gale]

the component I I screenshotted is not, but the actor it is on does use some... I will try unhooking that to see if it helps. I sort of assumed it's just the fact it's a component?

[lunar sleet]

Well a Construction Script fires everytime you change something, so it might be causing a reset of the details panel

[rare gale]

actually, I was looking at the wrong one. This one does not use construction script after all

[rare gale]

Was that directed to me? I am using structs. Not sure how GameplayTags would work for what I'm doing. Maybe something to look into?

could you just use append to add the key pressed to the same dash setup minus one dash?

[lunar sleet]

ah...i c. Is the struct defined in cpp?

[rare gale]

No, I'm fully BP

[lunar sleet]

may want to start defining them in cpp. Idk if it'll fix the issue you currently have, but bp only structs tend to break for no reason and you could potentially lose all data inside them at any given time, which I would imagine will be 10x worse than having to reopen every index.

[rare gale]

Yikes... Got a good guide on how to do that? I've only ever worked in BP so I have no experience there.

[maiden wadi]

My favorite for BP structs is still the circular dependency. Always fun to see.

[maiden wadi]

The TLDR is check out the C++ channel. There are guides on how to set up Visual Studio and build your project from it. Past that it's just making a new .h file in your project's C++ files to add USTRUCT definitions to them.

[lunar sleet]

I think you can even preview the header for bp structs to see how to set it up in cpp iirc what @frosty heron said

[maiden wadi]

You can, but be a bit careful with that. They're written oddly sometimes.

[sick sky]

can i make a BP exposed func hide the player controller pin if placed inside a User Widget ? and call the GetOwningPlayer method ?

[velvet bobcat]

Could somebody please help me with making the settings menu? I have a pause and a main menu, and I need to somehow get the settings menu to realize when to go back to the main menu and when to go back to the pause menu. (if its even possible...)

[faint pasture]

You need a state machine or a stack

If it makes sense that the current state of the UI is a stack like:
Game
Pause
Settings
vs
Game
Main
Settings
then a stack will do it, you can do the same with a simple state machine too, just remember the last state and "back" brings you to that

[maiden wadi]

CommonUI ❤️

[velvet bobcat]

thank you, Ill try working out how to do it.

[rare gale]

Well, it's taken all damn day but I figured out the issue. For whatever reason, having an index added by default in the component's variable for the root of my giant struct chain was keeping the ones I added manually in the editor (exposed instances). Removing that default one made everything work just fine. No idea why that would be, but glad to have it working

[velvet bobcat]

Yeah, I still havent found a way. To give more context Ig: Right now I have each menu as a separate widget.

[frosty heron]

I stop using it after a bit, you just know most of the data type after going back and fourth a few times.

But it really does help me when I first start.

[maiden wadi]

You need CommonUI.

[velvet bobcat]

CommonUI installed.. (Im guessing u meant the plugin) What now?

[maiden wadi]

Need to learn to use it. It has a widget called CommonActivatableWidget. An Activatable widget is like a primary widget. I usually think of them as menus or HUDs. CommonUI tracks these when they're on screen and has a system to "activate" the leaf-most one. Usually meaning the top most on in the viewport.

That is to say that your PauseMenu, SettingsMenu, MainMenu, and the widget you use as your primary HUD when in game should be ActivatableWidgets. You can simply reparent them for the most part.

Activatable widgets do multiple things when they're activated. Primarily they will set an input mode for you. By default this is Menu, or UIOnly so that it'll disable gameplay controls. For your HUD you'll need to override the GetConfig function to return Game or All based on your usual gameplay.

There are back actions in Activatable widgets, which you can set up. Such as making the escape key a BackAction key. So that when you press escape, by default it will try to run the back action on the leafmost activated widget.

So if you are in the main menu and have the settings menu up, you simply hit escape and it'll close out the settings menu and your main menu will become activated. If you're in game, and you have pause menu up, and then the settings menu, and you hit escape, you'll close the settings menu and go back to the pause menu. If you hit escape again this would close out the pause menu as well for example.

How you place the widgets is based on style, but there is a widget call a WidgetStack. You can push widgets to it, such as the pause menu and settings menu. What the stack does is allows you to push multiple widgets to the same stack, but only the last pushed one shows. As you remove them, the next one in line shows, etc etc.

@velvet bobcat Forgot the tag. But it takes some learning, and getting used to. But it is a fantasitic system to learn for UI handling. And it also comes with the major benefit that if you have any plans on getting into Gamepad use. Either for PC or consoles, CommonUI has a toolset that allows you to maintain focus easily in menus as well.

[velvet bobcat]

Thank you a lot! If something, Ill just reply again.. Time to learn now.

[faint pasture]

If CommonUI ends up being too big for your taste, you can just have an array of widgets that you consider to be your "stack"

if you're in a menu and open another menu, you don't just open it, you add it to the array and open it, then you can go "back" to the previous one when you close that one

[humble flax]

Hi, I set this bool "dodge" to be either true or false. I want to access it in this other blueprint called block. How do i do it?

[surreal peak]

The Boolean is in a widget?

Only way is to get the reference to that widget.

It's not really common or adviced to have gameplay logic in UI. Might want to move the Boolean into the pawn/character

Hi everyone, I'm pretty new to unreal, but I'm working on project involving OSC controlled lights. I have a light blueprint that gets a set of values from an OSC server, but for some reason I can't figure out how to set both the intensity and the color of the light at the same time - I can't connect both the functions to one event, and when I daisy chain them, neither works (the light just stays black). Could anyone help me out please?

Hi guys( I ask these also here), I'm new in the Behavior tree; I'm trying to make an AI enemy behavior tree that have a specific patrol path, but when see the player it starts to chase it. However if the player is in the bushes, the AI moves to the lastknownlocation and come back to patroling.
I'm trying to find a solution for this system.
Somebody could help me please?

Is there a way to get the an instanced variable (class default) of a component value, from a component on an actor class in blueprints

Ie I have a variable inside a component. on each actor this component is added to, the value can be set in that actor, and I want to read the default value based on the actor sub class. or can you only get it from a spawned actor?

Basically similar to the GetClassDefaults node, but for the components of that actor class

[odd widget]

hey all, 4 years in uni as a design student but ended up as more of a tech designer, i know BP is already slower that base code but was wondering if there was any place that i could find out how intensive certain actions are

ive come out with games previously and luckily they dont have too many issues but i know its a good thing to be vigilant of and id rather catch these things before they become a habit

[odd widget]

could i ask for a little more info on this question sorry?

it sounds like youre close with the class defaults, but you may need to link it specifically to the variable rather than "self"

[smoky plume]

okay that new enhanct input comfusing me just trying me to make quake game hahaa wishdir style

[lunar sleet]

Bp is roughly 10x slower than cpp because it has to go through a vm. Depends what you mean by how intensive actions are, if you’re looking for #profiling tools, there’s a few but Insights is the crown jewel

[odd widget]

WAIT 10x

alright, ive never actually had bp performace issues

[lunar sleet]

Because with today’s hardware, it can be less noticeable until you reach scale

[odd widget]

mostly issues have been artists or inexperienced designers/coders

[odd widget]

yeah, thats what i was wondering, cause that seemed near absurd to me 😅

[lunar sleet]

Sec, I think Ari confirmed it very recently

Scroll down to bp perf https://dev.epicgames.com/community/learning/tutorials/l3E0/myth-busting-best-practices-in-unreal-engine

So not 10x slower overall, but the effect is cumulative with each node

[dawn gazelle]

Worst parts of blueprint from what I've seen/heard:
Loops - especially for each loops if you use a pure function that retrieves the array that the loop uses programmatically as it'll end up calling that execution every single iteration.
Complex Math - especially if you reuse earlier parts of the math later on as again, each pull from a pure node will recalculate everything before it.
Can't always pass by reference - Utilizes additional memory overhead by more often using copies of things, made even worse when done with large arrays.

Otherwise, as NeoExcidious has pointed out, it's usually a non-factor due to today's hardware, and these kinds of issues won't usually show themselves as issues until you start getting into hundreds or thousands of objects that could be running them.

[gentle urchin]

Bp cant really pass by reference iirc

Loops easily come to a stall/limit, and it gets exponentially worse for every node you call within that loop

[frosty heron]

can be way more than 10X, it depends

Python is slow too, but it doesn't mean people stop using it. If the overhead for the operation isn't noticeable, then who cares.

but certainly no one will make a Triple A game engine with python

[nova parcel]

I don't think so.. because I don't want it to be by any instance of the actor object but I could be wrong

So if you have a variable on a component, that variable is set to instance editable, then you add that component to an actor, and then inside the actor on the class defaults view of the component (within the actor) you change the value to something else. Can you get that value from knowing only the actor class that holds that component. Without having a spawned instance of that actor.
(Also note, I mean the value within the actor, not the default if you only opened up the component itself and got the value there)

I would expect it to be something you can do.. but maybe its not exposed to blueprints. The only way I've found is adding code to look through USCS_Nodes? But that seems convoluted / something I'm not familiar with

[lime cairn]

My way of going through an array and appending a string seems to be wrong but I can;t pin it down. Instead of it appending a list [a,b,c,d] as abcd, it appends it as aababcabcd or something like that

and my brain is currently not working well

[lime cairn]

Oh it's correct, I just forget to clear hte string after each loop

[narrow sentinel]

Anyone know how to fix it so when the camera frustraum isn't looking towards an static mesh it doesn't cull it out

at the moment when I slightly look away from the static mesh it gets culled and I can't remeber where the setting is to turn that off

Dungeon Generator Progress: I've successfully created a Dungeon that generates randomized Rooms and "snaps" them together so their doors join.

I'm using "Find Path to actor/location synchronously" to draw a spline from my avatar to wherever they need to go to show said path
The problem is, when I'm moving the avatar to interact with an object (like a chest or something), I can't draw a spline because there is no navmesh under the interactable object.
Is there any similar method to Find Path but for example also take into account the target's capsule or just some sort of "accaptable radius" ?

There isa lot of things that are wrong but first of all your cast node(s) are are impure, and impure nodes require flow in and flow out, you have only flow in

convert them to pure or re-organize logic flow

Okay, thanks, what else?

I converted them to pure cast

This is the link: https://www.artstation.com/artwork/r986eJ

[restive snow]

alr (here is the thing for context)

how would i make the BP actor to represent the map

I've made the Actor

[dawn gazelle]

You need to rethink what you're doing here....
Right now your steps are doing this:

1. Get Player Character 0, Cast to custom "BP_CombatCharacter_Player_GKnight"
2. Get all Actors of class "BP_CombatCharacter", loop through them, cast each of them to "BP _HumanoidEnemy" (Not even sure why you need this cast assuming your BP_CombatCharacter class would have the enumerator you're seeking)
3. Compare the enumerator from your PlayerCharacter and the enumerator from the last iteration of the loop as that's what would be referenced in your final execution path.

This is also potentially error prone. If the objects don't properly cast (object is the wrong class, object is invalid, etc.), you're still attempting to access the casted value which will throw errors if that happens.

What specific "BP_CombatCharacter" exactly are you trying to compare your player with? Right now your code only utilizes the last one in the array which may not be the one you actually care about.

[dawn gazelle]

You don't. What are you trying to do exactly?

You normally don't try to reference the map from other blueprints. It's not really possible, not great for memory, nor is it really necessary.

[restive snow]

ok

[gentle urchin]

I suspect this must be custom behaviour

erh,. ill move it to EIS channel, my mistake, i forgot that existed

[split wasp]

I would say you're in for world of pain if you try to copy camera mechanics from newer mario games, regardless of the language

and multiply that by x5 if you want to implement custom gravity elements from Galaxy

[glass hawk]

hay so i have these spline instances i made via blueprint but when they get merged down they start to shift very much
and i cant explain myself why they dont just merge down as they are

looks like this then

[maiden wadi]

What do you mean by merge?

[feral parrot]

How can I select the variables randomly and add 100?

[restive snow]

best rotator replacement? I want to make it move only Y axis like directly up and down.

[glass hawk]

so these are all spline blueprints writing into a instanced static mesh

[restive snow]

this is how the camera is (the yellow). I want it to go directly Y

[crisp sandal]

what is the difference between these two and any recomandations mostly write in cpp have done bps for a it but don t really like it because i don t know how all the thingies are called 😅

[maiden wadi]

Switch on Int

[glass hawk]

and since my level is so big i have like... 900 of them xD
so i want to have them all in a packed level actor so they get merged down into corresponding instanced static meshes
so instead of 85 of these blueprint actors i have like 7 instanced static meshes because im using different meshes on them

[restive snow]

ples

[glass hawk]

this is my setup btw

[feral parrot]

didn't get you sorry, I meant I need to select one of these, add 100 and set it.

[maiden wadi]

Makes sense. To some degree. Don't forget that if your level is large you get better performance by letting these stay smaller for smaller bounds that can cull out.

[maiden wadi]

This is the merging from all to one?

[maiden wadi]

Instead of Select. Switch. It has execution lines.

[glass hawk]

this is the construction script of the blueprint actors

it has a randomized scale and rotation

it then puts everything in a instanced static mesh
but when i merge these down so if i take 2 of these blueprint actors and merge them
they rotate weirdly like that
my hypothesis is that the merging down messes with the pivot orientation... which it shouldnt so then they rotate the right axis but rotated

[maiden wadi]

Can you show your merging code that is taking these from their BP ISM to the single one?

[rough pecan]

I'm having a weird issue where a line trace by channel is creating two lines, one is perfectly straight and the other follows the trajectory I want, anybody know why that would happen?
Here's the bp for reference
https://blueprintue.com/blueprint/w-7auq1h/

[restive snow]

how do i get this?

this is the larger image I am copying

[dawn gazelle]

If you promote the random int to a var, then you can do something like this... (Actually, it may work without the promotion of the var because the return value is feeding into the same node)

Alternative that Authaer suggested:

[glass hawk]

there is no code for that its just they get merged down via putting them into a packed level actor or batch merging them via the merge actor tool ^^''

[rough pecan]

if you grab the reference to your camera and pull it into your BP you can pull from that pin and search for "Field of View" at the bottom it will say "Get Field of View", that's the one you want

[last ingot]

Understandable. I'm not attempting to mimic the entire camera system and its mechanics as this is a small scale university project. But the default camera as it is, is not very pleasing to the eye. So I thought of making just a few mechanics at the very least the ones present in the link I put up above. But I'm facing problems with figuring out what exactly modifies or sets values directly to how the default CameraBoom (Spring Arm) and FollowCamera (Camera) works. Let's say if I want to simply interpolate the camera zoom-out to the CameraBoom's target arm length after obstructed by a wall, I can't find any means to interpolate whatever that value is, but rather it snaps back in an ugly way.

[last ingot]

yup I'm definitely not gonna implement gravity elements from Galaxy XD

any pointers or help is greatly appreciated.

[dawn gazelle]

One is the second edition, the other is the third edition, meaning one would be more up to date. Really though, they're probably both out of date.

[maiden wadi]

That's a bit odd then. :/ I'd be curious to know what is causing that if you ever find out but I haven't used that much, I tend to do things a bit manually. Judging the images at least, position looks relatively correct, but scaling seems to be messed up.

[split wasp]

camera boom is really just linetrace with small sphere at the end to prevent camera from clipping outside the map from small gaps, so replacing the functionality with your own is fairly simple

[glass hawk]

yeah seems like it but... i really dont understand it :/

that makes optimising my project basically impossible...

[proper flower]

quick question: how to block the rotation on a specific axis on a component? like the spring arm

[restive snow]

I'm not getting

[split wasp]

physics components have separate option for locking transformations, other components need to calculate their rotation from reference point

[restive snow]

I went on to my Camera reference but how do i pull it from PIN?

Now i got it!

thank you very much good sir!

[rough pecan]

Nice! Glad to be of help

[last ingot]

sorry to ask further, but where exactly do I find this line trace and small sphere and affecting its functionality? do i have to go to its class itself and change it in cpp or is this doable in blueprint within my player character's blueprint?

[split wasp]

I mean CameraBoom itself is just Linetrace + Spheretrace at the end, which you can do manually in blueprint too but you can add your custom behavior to it

[last ingot]

the thing is, I wanted to add interpolations when it moves rather than snapping to place by default, which sounds as straightforward as making it so that it goes back to target arm length smoothly, which is what I did, but I realize that's an unchanging variable

neither is its World Location, as its location is separate from its arm length, so its current to target are unknown to me, even then it still overrides whatever interpolation I set for it (by tick) and snaps like usual

[split wasp]

you mean camera snaps to surfaces? that is the intended behavior

if you really want something that smoothly slides through the objects in the event of collision, you gotta do the location math for the camera manually

[shrewd tiger]

Hey guys. I've got a character comprised of a camera and a static mesh component that's added in runtime, on possess event. then, the mesh is set - somehow it's not visible...

According to the debugging print i put there the SelectedNozzle integer cycles as it should

or should I just put the components there to begin with

[last ingot]

the other way around, the zooming out once moving away from a colliding wall (as the linked feature study above shows), so not through an object but rather after moving away from an object it interpolates back to its full arm length, regardless I did the location math, but the issue is to what exactly?

I tried with the world location, does not work, neither does the target arm length, it's just about what variable or component should I be affecting exactly

[split wasp]

oh I see

[shrewd tiger]

ok nvm i fixed it

[split wasp]

one way I could think is to detach the camera from the camera boom, add empty component to the boom end, then place the camera somewhere between camera boom location(which is its root) and the formentioned scene component

simply setting camera location between those 2 points with lerp function should give you like a camera rail effect

[last ingot]

will try it out, thank you

[desert stream]

Guys I’m having a weird problem where I’m not sure if it’s to do with blueprints, a third party addon I have or something else.

Basically some logic events will be ignored and skipped when the game is running on low fps, usually under 20.

Is that something common anybody could help with!?

[split wasp]

it's probably not gonna be what you had in mind, but it should be a solid starting point.
Just experiment different ways to place the Camera between those 2 points

[gentle urchin]

Editor utility tool can make replacing them easy work

Alternatively you separate the spline bp from the ism bp

And have some editor callable event in the ism bp, finding all spline bps, laying out the bricks on them

Ah I see it appears I have to have a sound attenuation affiliated with that sound. New stuff to learn then!

[frosty heron]

that's it

[rare gale]

What is returned if an array find node doesn't find anything?

[mental trellis]

If it's returning an index, thjen it'll be -1

[rare gale]

that's what I thought... thanks

[frosty heron]

if you hover over the green node when searching for index, it should say so

[thin panther]

indeed it does

[midnight field]

I'm planning to make a rail grinding system like that of a Tony Hawk game, but I'm noticing there's a difference between a SplineComponent and a SplineMeshComponent. If I'd designed these classes I might have the latter be dependent on the former, so both use consistent spline logic. But I'm finding that they seem entirely separate.

So I'm on the fence about which to use. The mesh is nice for including collision and such, but the basic spline component seems more flexible due to being pure data.
Those who are more familiar with Unreal's paradigms, which would be the better approach?

[glossy cloak]

Hey guys. I'm trying to make a painting system that does a line trace, returns the material SLOT of the static mesh component hit, then changes that slot's material.

I'm running into some issues with how to get that info. My collision response gives me a hit face index, but that seems to always return -1 no matter what I try.

I searched around a bit and saw that it might require a complex as simple collision so the collision data could return the face data, but that still doesn't seem to fix the issue and I'm still just returning a -1.

Any ideas?

^ I think I found the solution. I think I needed to trace complex.

Edit: Nope. Still not working.

[dawn dragon]

hi, i made a behavior tree for an Enemy that im creating. to test it, the BTT_ChasePlayer task just picks a random location and moves to it. I have the nav mesh and it has green in it. When i click play, the walking animation of my model plays, but they dont move. I put this in the Tick function of my Enemy so i can see its location, and it also doesnt change.

void ALightEnemy::Tick(float DeltaTime)
{
    Super::Tick(DeltaTime);
    UE_LOG(Enemy, Log, TEXT("%s"), *GetActorLocation().ToString());
}```
The animation is from a blendspace which is determined by the magnitude of the Charachters velocity.  But its not moving (log mesage every tick shows its location is not moving) so its velocity shoudl be 0?  but it has a walking animation playing so its velocity is also non 0?

TLDR: My Enemy is walking in place and not moving, despite its animation being triggerd by its velocity

[hoary summit]

I want to stop the AI from killing each other, and will also use it to prevent friendly damage in multiplayer. Humanoid Enemy is my enemy, both that and the player character are derived from the same parent, combatcharacter. I am trying to get a reference to which team is assigned. What is the best way to do this you think?

[normal ether]

Hey all, I had heard this was a known engine bug.

I add a new component called Interactor from a plugin to my pawn blueprint, however on reload of the project it somehow gets removed and the following error is shown:

Component class is not set for 'Interactor' - this component will not be instanced, and additional warnings or errors may occur when compiling Blueprint 'BP_ThirdPersonCharacter'.

How can I solve this?

I have tried turning off the plugin, restarting , and turning it back on.

I have tried regenerating the Saved/Intermediary/Binaries folder. and no luck

[ionic ore]

Can anyone help me out? First time using Unreal and blueprint, and I'm try to do something that should be simple but honestly I cant get heads or tails with it.

Trying to make a mod for a game where all I want to do is append new values to the modactor class, however I'm totally lost on how to actually do that appending part. Basically modactor called newblueprint5 has a variable called "a" with Name Type and Float type as its entry fields, and I want to add my own entries into this.

I have an event beginplay to get all actorsclass in another modactor that gets called on game load, but I dont know exactly how i'm suppose to add my own custom entries into the newblueprint5 "a" array?/map?.

Example entries that I would like to append to it:
“Key”: “drive”,
“Value”: 10.0

"Key": "burger",
"Value": 5.0

"Key": "batts",
"Value": 10.0

[round spruce]

is it possible to not make my actor component rotate with the actor ?

[dawn gazelle]

If you're sure there is only going to be a single "NewBlueprint5" spawned, instead of using "GetAllActorsOfClass", use "GetActorOfClass" which will return a single reference. From that reference you would need to get the "a" map, and use an "Add" node to then add your own key/value pairs to that map.

[tidal marlin]

Just rotate Actor, and then set up last rotate to your child component.

[faint pasture]

You probably need both

unless you want to grind invisible splines in the sky

The spline is the, uh, spline

the spline mesh is a mesh that conforms to a spline

[midnight field]

The spline mesh seems independent, is it intended to adhere to a spline component?

[faint pasture]

It's been a long time since I touched splines. It's either that or spline mesh component is a spline + the mesh conforming stuff

either way, you'll want spline mesh components

[midnight field]

Ah, hm... I have an idea about how this could work. Will need to experiment. 🤔

[trim matrix]

Does anyone here know if Lyra changed heavily BP-side between 5.1 and 5.5 ? I’m currently planning to convert my project to 5.5.

I know there was a Input refactor in 5.2/5.3 but it was minimal and more cpp sided so I think I don’t have to worry about that

But dunno about the rest

[ionic ore]

I see, I understand but im confused as to how I can get/target the 'a' map. I cant find the correct node to do so

what is the node speciifclaly called to Get/Target the map?

i cant find it in my list

[lunar sleet]

Stop what you’re doing for now. Google your first hour in Unreal and do that first. Then, watch the first video in the pinned links from this channel in its entirety. Then you’ll actually understand how these things work

[ionic ore]

okay i believe I found the correct node, thanks

[fading sail]

Saving arrays of BP instances?

I have a data-only BP class derived from just Object (not Actor etc) with some public vars that all have Save Game ticked. Also have a custom "BP_SaveSystem" class derived from Save Game which has a simple array variable (also with Save Game ticked) of the above BP class. Problem:

When I add a newly-constructed object to that array and save-to-slot, a subsequent load-from-slot will have the correct and expected array length but all the items are not-valid (null in non-BP-coding parlance).

What am I missing or doing wrong here? Do I need a different base class to be serializable? Is the Save Game checkbox not sufficient? Shouldn't it then be disabled UX-wise? Stumped & thx for any ideas =)

[tropic token]

guys, what does it generally mean and what to do with that?

[fiery swallow]

Don't put function calls that aren't threadsafe inside of anim instances because anim instances are ran on a separate thread

Set the value you're looking for in the event graph or somewhere equivalent

[tropic token]

I'm just not sure what to do with that. I need to see if tag is on the ASC, how to do it properly?

[fiery swallow]

^

Store it as a variable ofc

[tropic token]

But I need to update variable somehow, so it seems I need a delegate to do it

[ionic ore]

how would i go about finding the 'a' map with get all actors node? The get actor node didnt seem to work for my usecase, but i cant find the node that is compatible to get the 'a' map for all actors node

[fiery swallow]

Just take that same function and set it as a variable in the blueprint event graph

[tropic token]

Like where? In tick function?

[fiery swallow]

If that's what your game requires then yeah

[tropic token]

okay, seems like I need to do a delegate. it's not a big deal

[fiery swallow]

So long as you store the boolean as a variable, and plug it into the animgraph then yeah you'll be fine

[fiery swallow]

Foreach loop

You will still need a way to figure out which specific actor you are trying to modify though

[ionic ore]

like this?

[fiery swallow]

Get all actors of class is going to be very difficult for you if you don't understand instances and properly and how to reference specific actors

[dawn dragon]

Any reason why AI Move To would make my animation activate (which is a blendspace based on the Charachter velocity), yet it doenst acctually move? my dude just walks in place

[fiery swallow]

Is your blendspace actually setup correctly? I've seen cases where people setup a blendspace to move so long as the velocity is greater then 0

Which is not desireable

[dawn dragon]

even wierder, if i print out its velocity in Tick, its 0, 0, 0, so its magnitude shoudl be 0, but the animation blendspace is set up to walk when the speed is greateer than 0 so how is it 0 and non zero at the same time

[dawn dragon]

i believe it is, but either way printing out teh velocity is X=0, Y=0, Z=0, so the velocity is 0, ill show you my blend space

[sick sky]

Yeah there is a setting to enable for that

Google "ue5 ai moving with no animation"

[dawn dragon]

its the opposite problme

no moving but i have animnation

[sick sky]

I dont remember the setting name but its a bool to tick on the pawn/character

[fiery swallow]

Are you setting velocity -> vector length? If so you should print out the value of vector length and see if it's also greater then 0

[dawn dragon]

yes

[fiery swallow]

Print out the value

[sick sky]

Oh, is the AI blocked by some navmesh volume ? Or is it reachable

[dawn dragon]

i did that too in Tick, in my Behavior Tree task

it prints out velcoity is X=0, Y=0, Z=0

[dawn dragon]

yes

all flat ground

[dawn dragon]

i have more screenshots up her ein my earlier post

[fiery swallow]

I am not positive get velocity from actor is the same as get velocity from character movement comoonent

[dawn dragon]

as well as more detail

[fiery swallow]

Comoonent

[dawn dragon]

oh

any reason why?

[fiery swallow]

Also, why aren't you printing out the "speed" variable directly

[dawn dragon]

probably because idfk what im doing

[fiery swallow]

Lol

In your animation blueprints

[dawn dragon]

im following a youtube tutorila to makea behavior tree

[fiery swallow]

Just get thr speed variable here and call print string next to it

[dawn dragon]

my Charachter is C++ not blueprint

thats the only difference betwen mee and the video i think

that and the engine version but we are both UE5 so i think its fine

[fiery swallow]

Bro print out the speed variable the same way you printed out the velocity variable <.>

[dawn dragon]

okay oaky lemme try

wait here

plz

[fiery swallow]

Just drag the green pin into "in string"

[dawn dragon]

look good?

okay so

u are right

speed is going up

in the cahracther movemenet component

[fiery swallow]

There's your problem boss

[dawn dragon]

but not in in the thing itself

okay so please tell me the relation between the UCharcahter and its movement component

[fiery swallow]

It is moving, just so slightly that it's basically not.moving

[dawn dragon]

well when i print out the positoin every tick, it doesnt change

[fiery swallow]

It f*** blows

[dawn dragon]

so i dont think it moves at all tbh

[dawn dragon]

oh damn

that bad

[fiery swallow]

Realistically it's the best thing you're gonna get for free

[dawn dragon]

call me crazy but if i have a UCharachter and its MOVEMENT component MOVES the charachter should MOVE too?

[fiery swallow]

Outside of making your own

Character moves through the Character Movement comoonent

[dawn dragon]

so there is come kind of dicsonnect bwettn my UCharachter and the movements compentn?

[fiery swallow]

No, not really. Without seeing all of your code there's no real way for me to tell you what's happening

The character movement component has a lot to be desired, but it's good for free

[dawn dragon]

woudl you be down to look at it 😭 ive been at this for like 14 hours split across 3-4 days

i jsut want this dude to walk around 😭

[fiery swallow]

The quickest fix for your problem is to increase the threshold on your movement animation

[dawn dragon]

you can say no i wont be mad lol

[fiery swallow]

Anything above 0 is not a good condition to be considered playing a moving animation

[dawn dragon]

i have more screenshots up here

[fiery swallow]

Just raise the speed threshold from 0 to a reasonable number bud. I'm in bed right now eating fam

[dawn dragon]

its 2 am for me

tf does that mean

jit i never even used a game engine until a week ago

chagning the threshold for when the animation starts wont make him move tho?

he still gonna walk in place?

i fail to see how they are related. it is my understanding that the animation is applied to the model independly of how its moving, i just happend to link it to its speed

so changing at what speed the animation activates would not make my dude move?

right?

[fiery swallow]

If the speed is less then say something like 100, then play the idle animation, if it's greater then play the blendspace regularly, or you can just re add the same idle animation inside of the blendspace at a different speed

[dawn dragon]

also, my blendpsace 1d has an idle animation for speed 0, and at speed 100 it has a walk animatino

[fiery swallow]

Right

You can add a 3rd animation in there that's also idle

And set it to like a speed of tp

[dawn dragon]

okay but how does the blendspace relate to geting the model to actually phsyically move to a new location in the world?

[fiery swallow]

50

[dawn dragon]

the problem im having isnt the animation i dont think, its that the dude wont move

sorry if i sound like im repeating evyerthing

im just not seeign the connection here

[fiery swallow]

Thought the problem was that the animation was playing when you weren't moving

[dawn dragon]

no

the animation is fine

he just walks in place

he is idle and does thoe idle anitmation

then when AI Move To is called, he walks liek hes supposed to

he just wlaks in place

the model itself does not move

[fiery swallow]

What value was speed printing out

[dawn dragon]

the velocity is printed out during this time from the Animation blue print, and is non 0, and in the Behavior treet ask i print out the velocity from the charachter, not the movement component, and its 0

speed value was 600 during walking animation and 0 during idle

[fiery swallow]

Weird, the only thing I can think of without looking through your code is, movement mode is incorrect, the destination you're plugging in is causing issues, you're continuously overriding the AImoveto node. If you don't figure it out by tomorrow you can honestly ping or shoot me a message, I wouldn't mind calling and helping you

But I'm about to knock out for the night

[dawn dragon]

ive been working on this for days 😮‍💨

if you would be so generous as to let me dm you tomorow i would be forever in your debt

i am trying to learn this as fast as possible

i promise im not stupid i can do it

what time zone are u in, ill do my best to get a reasonable time for u

[lunar sleet]

Use Visual Logger to find out why your AI is not working properly

[gentle urchin]

when using float curves for things like level to damage curves , is level as "time" my only option?

seem alternatives are not bp exposed

nvm, I dont need it bp exposed. just EditAnywhere

seems like floatcurve is the only option , oh ewell

[ionic ore]

is this totally incorrect? Im unsure if the issue is the blueprint or if theres an issue elsewhere with what im trying to do

just trying to remove/add variables to the "a" map of this actor

but I dont believe its having any effect

[gloomy fox]

anyone know how the new "instanced actor" system works in ue 5.5?

[dry sleet]

If there are multiple instances of that blueprint in the world, that node will pick one essentially at random.

It's very rare for GetActorOfClass to be the best approach to retrieving a reference to an actor in the world.

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

Watch this video if you haven't.

[graceful cairn]

Hey everyone, I have a weird issue I don't understand, the CurrentlyDisabledNode variable always takes me to the Is Not Valid route even though I set it the first time the Event hit fires (when it is indeed not valid because null). It even tells me it is valid with the last print string there, how can this happen ?

[gloomy fox]

nobody? there's also no documentation to this apparently 🙄

[graceful cairn]

I figured it out myself, since the logic is tied to a projectile bp that is destroyed after firing everything gets reset the next time I fire 😅

[restive snow]

how do i fix my camera being in an angle?

this is the camera setting in viewport

hold up i fixed it

[spark steppe]

this seems new to me (5.5)

or never noticed it before

[dry sleet]

The Create options aren't new, they've been around.

[undone bluff]

yea I've seen it way back

[spark steppe]

god damn, i've always added them manually 😄

[undone bluff]

however issue is it will only set the variable type and name, not values

so I tend to copy them instead before pasting in the nodes sometimes

[spark steppe]

yea that makes sense, that can be important in some cases

[dry sleet]

Haha yeah you really live and learn with Unreal's many secrets -- I was equally surprised to find the option "Move to Parent Class" when someone pointed it out a while back.

That would have been really handy in the past for me!!

[spark steppe]

didn't knew that either xD

[dry sleet]

Two conveniences in one stroke!!

What a happy day

[gentle urchin]

Doesnt work for native parents 😦

That'll be a joyful day , if it ever comes

Unlikely as it is

[dry sleet]

It works alright for POD types.

If you declare them natively with the same name and specs, the BP compiler will simply start using them next time it loads the blueprint.

It's very nice. However, my big grievance is that it doesn't work at all for components.

Most of my issues stem from trying to move components to native code.

[gentle urchin]

Yeah thats my most frequent usecase ^

[willow gate]

Hey folks. I've been looking but I wondered if any of you know of any apps or websites that let you build blueprint flowcharts just for planning outside of the engine. Like flowchart software but for blueprints. Not a pastebin but a planning tool. Just curious.

[broken wadi]

https://blueprintue.com/ is the only one

[maiden wadi]

You may as well consider a generic programming planning tool. Blueprints in themselves are just blocks of logic and practically a planning tool. If you need something more, then your logic ideas need to go in more generic blocks, which will fit in any programmer planning layout.

[willow gate]

That's exactly what I do right now. It would just be nice to have visuals that matched UE if there was something like that out there. Nothing critical.

[willow gate]

Right. I use this all the time. I'm not looking for a pastebin. Just a flowchart tool. All good tho.

[maiden wadi]

Ah. I doubt it. In the grand scheme of things, Unreal is a tiny fish in the pond of programming, so it isn't really worth much to focus on it for something so generic.

[willow gate]

I figured as much but you never know. You know how it is. People sometimes dedicate insane amounts of time to make crazy niche tools. It was worth an ask. Thanks guys

[eager python]

Got a good tutorial for it? Last I knew, PCG wasn't in a good place for things like dungeon generation. I'm considering using it to place decorations / clutter though.

[maiden wadi]

O.o Who the fuck said that?

[sick sky]

i mean PCG can be overkill, but its legit the best tool for procedural generation

[eager python]

The UE devs in their Twitch stream around the launch of the PCG tool. I asked them directly if it would work nicely to create structures such as dungeons or rooms within buildings and was told no.

[sick sky]

its been more than 1 year

[eager python]

So, also old information at this point

[sick sky]

PCG is solid

[eager python]

But that's why I ask haha

[sick sky]

depending on the variety of your generation you can use PCG or just some regular actor spawning in a main manager

for example for my endless runner i am not using PCG

[maiden wadi]

Lol. That's sad. I mean imagine making a tool and telling people not to use it for it's primary purpose. 😂

[sick sky]

PCG is not easy to learn for precise stuff like rooms IMO

[eager python]

The "Rooms" in my dungeon aren't actors either. So I can't just put a bunch of Room actors into the tool and make it drop them.

[maiden wadi]

It's very good at precise things. They're just points. You make a graph that picks room placements and filters them out based on conditions. You could easily run the entire graph and then just place rooms on the spots. Can even run smaller PCG graphs after placing the rooms to decorate them.

[sick sky]

im debating on the learning curve

i know PCG is great

[eager python]

Does that approach allow interesting/randomized individual Room layouts, or do we end up with a bunch of squares connected by hallways? Any time we start talking about "graphs" I get worried.

[maiden wadi]

It allows anything you want. PCG is a generic tool. So you can do whatever you like.

[eager python]

I'll have to look into it again I guess. Was planning to use it to decorate anyways, so we'll see if it changes the way I want to do things.

[thick prairie]

Hey guys. I have an issue with my character. I was setting up all the constrains for my skeletal mesh and i think i messed up something with the root collision. Now every time i want kill a character and fire up ragdoll physics it gives me this error even though i BP, i have "Set Simulate Physics" enabled. It was working fine before i started messing with the physicsAsset

[round spruce]

what could make the break constraint node on physics constraint Not break it ? i dont understand

[open dune]

how can i make projectile collisions accurate? you can see here the impact of a projectile when it overlaps with me. i was not moving. it just looks really bad imo
https://cdn.discordapp.com/attachments/978053882905243658/1307041766838374503/image.png?ex=673ad740&is=673985c0&hm=3016cc9b489f1dcfbf863eac9fab0483964f86e0da96100252868cb0d7c5a673&
tried using CCD or Hit instead of overlap, makes no difference

[broken wadi]

Put the logic for what should happen after a collision happens onto the static mesh of the ship itself instead of a capsule collider. Also make sure to use complex collision as simple.

[broken wadi]

https://dev.epicgames.com/documentation/en-us/unreal-engine/simple-versus-complex-collision-in-unreal-engine

[open dune]

turns out i didn't have that option so i went into the static mesh and explicitely set as complex

[open dune]

ty

[lunar sleet]

Is that inside a function or event graph?

[spark steppe]

function (haven't checked if it would work in event graph)

[lunar sleet]

Oh yeah, I’ve used create local before I think

In fact I’ve used both creates but only when copying var nodes from another bp into one where they don’t exist yet

[lunar sleet]

The local only shows up in functions afaik, but you can still use the other one in normal graph

[austere orchid]

Hey,
does anyone know what "Include Only On Disk Assets" does?
does it include only on disk assets with assets that aren't loaded in memory, or is that misleading?

[proven loom]

anyone know how to show a compiler warning when a certain condition fails?

i want the compiler to remind me to set something up correctly if i compile it

[spark steppe]

for BP custom validators

and/or unit testing in general

https://www.youtube.com/watch?v=ovpiYkYFlPM&t=428s

[proven loom]

omg ty

[proven loom]

dude this is incredible

[frosty heron]

This is gold mine 👀

[spark steppe]

yea the whole talk is worth a watch

some nice things covered

[frosty heron]

Can't believe it's soo easy to customise the detail panel. Like adding slider, button or anything from slate

I don't know how modules work in terms of export though. I've only made one for my project.

What if I want to share it on a repo? I don't suppose they can just copy the folder and build?

[spark steppe]

you can pretty sure slap it into a plugin

[frosty heron]

Is it possible to make editor only plugin?

Without wrapping everything with #if with editor

Oh wait we can put modules in plugin 👀

[spark steppe]

like half of unreals engine plugins are editor only 😄

[fiery anvil]

Anyone know why this happens? i am level prototyping and i have it setup so when you step on that block it will use a level sequencer to move up like an elevator, but my character starts freaking out when i do that.

[digital palm]

is there a way to hide all bones except hands?

[versed crypt]

quick question, how can I cast this to player controllers actor/pawn? (so player can use any different pawns and this will still work?)

This works but looks wrong...

it would activate if it overlaps with anything, so i want it to activate if player stands on it and not random object falls on it

[broken gazelle]

You can check if the other actor is equal to the controlled pawn

You want the controlled pawn, not the controller itself

[versed crypt]

oh mixed up nodes. yes, thanks alot! 😄 simple answer...

[past jungle]

Hello!
How do I do predicted custom movement in blueprint? (Not in the face, please)

[thin panther]

Short answer: you dont

[past jungle]

What's the long answer?

[thin panther]

You can, but it's not going to be fast, and likely will have have stutter.

BP just isn't built for that kind of thing, you would do it in C++

C++ ends up being a necessity for anything but the simplest of multiplayer games

[past jungle]

Ok, are there any decent plugin options? I've heard people talk about the General Movement Component a lot. I'm using GAS with some blueprint plugins at the moment, but I've also heard that those two don't play nice together.

[thin panther]

General Movement Component is a lot more bp friendly afaik, but I haven't used it.

I'd bite the bullet and learn c++

[past jungle]

Maybe I will someday, on that distant horizon when I can open a brand new project in Visual Studio and simply click compile without it imploding on itself.

[thin panther]

You can do that

Unfortunately though you don't have a choice for remotely complex multiplayer

you either write it, or find someone who can, or build everything from MP plugins pretty much

[faint python]

I don't spend to much time in blueprint so I havn't figured it out myself but if anyone here understands I would love to know haha. How does the 'q' shortcut to straighten lines work for which one is moved? I know I can just right click the output/input and straighten from there to match the selected one, but how does Q pick what one is to be moved? It's been driving me insane because I think I figure it out and then nope next node is different aha

[lunar sleet]

depends on which node you select first

[past jungle]

Just to make sure I'm covering my bases, none of the new 5.4 / 5.5 shenanigans with motion matching or whatever address this shortcoming?

[lunar sleet]

it always aligns second selection to the first one @faint python

[frosty heron]

Gmc is 650 dollars even then it's not entirely pure bp friendly

[lunar sleet]

well there's always Mover 2.0 tho idk if will do what they're looking for 😄

[frosty heron]

Mover 2.0 require cpp too

[lunar sleet]

ah then gl hf

[frosty heron]

There's no bp solution for network movement

Afaik

[lunar sleet]

makes sense, doing networking in bp is a bad idea to begin with lol

[frosty heron]

And when using cmc, some people just keep brute forcing their way and fight the system with blueprint only.

None of them ever work

[faint python]

Ahhh I only ever use box selection when doing it but thank god this way aha I can't believe I never tried that

[faint python]

THANK YOU

[lunar sleet]

Yeah I usually just click 1st node, shift click second node (or shift+drag for multiple) and hit Q

[inland walrus]

multiple NPC's all moving to the same destination, how to make them not forcing to walk into each other? or perhaps making the npc's part of the navmesh

[lunar sleet]

you can use an EQS Query Context for the goal location for instance, so they each get a point in a circle around the target

[inland walrus]

Can you dumb that down for me a little 😅

[lunar sleet]

not really. you need to research EQS and EQS Query Contexts

and AI in general

[past jungle]

Assuming I get into C++, how difficult is it to make custom predicted movement? On a scale of 1-10
where 1 = creating some child classes and copy/pasting some lines, ChatGPT assisted
and 10 = spending 5 years in a monastery meditating on the engine source code, until my visual cortex processes the color of a rose in hexadecimal.

[inland walrus]

Alright

[frosty heron]

Chat gpt not gonna help you, look at delgoodie cmc tutorial for breakdown and examples.

But you will have to learn basic cpp syntax. Give your self time to finish learncpp.com

[thin panther]

Depending on your network skill, I'd say probably around a 7-8

that's due to the complexity of the topic though, not the language

[thin panther]

[eager thicket]

I want to smoothly interp between two floats based on a bool, how would I do this?

[thin panther]

what do you mean based on a bool?

[eager thicket]

well i guess a bool would be true or false

so if 1, it stays as one float, but if 0, it smoothly changes to another float
back and forth

[past jungle]

Thanks for the input all. Maybe I'll pay a visit to the freelancer boards 😆

[eager thicket]

the use case is im trying to change an animation blend depending on a bool

based on the silence im guessing it's either too dumb a question or not possible 😭

[lunar sleet]

I mean Select Float and Bob's your uncle

[lunar sleet]

just need a lil more patience is all 😄

that's for 2 floats, but ig if you need to run an interp, then just use a normal branch

[eager thicket]

what would a smooth interp look like based on the bool?

[eager thicket]

didn't know about this node, thanks

[lunar sleet]

well idk that much about animation, but you can use a timeline with a lerp for a smooth transition. There's also FInterp tho I don't use that often

use Near Equals if checking floats though, else you'll have issues with your branch returning unexpected results

because 0.0000000001 is not exactly 0

[subtle shoal]

I'm modding a game and found an event that's outputting a value that I need to trace back to it's source. How do I go further upstream from this custom event?

[inland walrus]

Any ideas on why the enemy counter on the right is always short by 1? There are 7 npc's and it's only registering 6, a delay fixes it but also causes a different issue

[lunar sleet]

Just find all references that’s the fastest

But if it’s called from too many different bps you can always use the blueprint debugger and check the stack

[subtle shoal]

I must be misunderstanding you because that just shows me references in the current Event Graph.

[lunar sleet]

Ugh UE4. You should see binoculars in the search results window, click that after

[subtle shoal]

Thanks.

[subtle shoal]

Well, poo. That went literally nowhere. It has a singular reference.

[hoary nest]

I'm trying to make a blueprint interface event into a function. What is the best way to do this if the event has no output? I know of the following methods, but they all have downsides.

1. Call a function from event
2. Add output that I simply don't use
3. Add output, implement as function, remove output (Editor still says the function is an event when hovering, so this is pretty sketchy)

The reason why I want to make it into a function is that I prefer using sequences rather than long lines of nodes, so I want to be able to return at any point

[copper chasm]

number 1

[hoary nest]

I guess that's the normal way to do things. I've kinda settled on number 2. Since I want to return at any point (on failure), it makes sense for my function to have Success boolean parameter regardless of whether I use that or not

[inland walrus]

bump

[lunar sleet]

Look for Call OnZoomFactorChanged

[subtle shoal]

I don't know how that's different than what I just did. A call and an instance of a node are the same thing, right?

[lunar sleet]

Not for event dispatchers

Tho to be fair that looks more like an override

[lunar sleet]

Those are 2 refs btw. One is a bind the other is the event

Did you 2-click the second one?

[subtle shoal]

That is the event which pulls or creates the value I'm interested in. Zoom Factor can have three values, 1, 1.35, 2. I need to change them to 1, 2, 4. A I don't understand how a user keypress is changing that value, yet I can't find the key event that does so.

[lunar sleet]

go to where it's being called to see what input it is getting

That ZoomFactor float needs to be fed from somewhere

and if it's nowhere in any of the blueprints, it may very well be called from C++

also check if it's not in a function. Pretty dumb of them to bind an event to a function with the same name but eh, I've seen others do it

[subtle shoal]

I'm afraid that may be the case, but another modder already did nearly the same thing that I did, adding another zoom level while leaving the two original values there.

[subtle shoal]

Find in Blueprints searches functions.

[lunar sleet]

go to the ZoomFactorOffset, it prly has a diff name where it is being fed

assuming they're not completely different things that is

if not, it is highly likely onZoomFactorChanged is being called from a cpp file

you can search the solution in VS for that function

[subtle shoal]

They appear to be different variables.

[lunar sleet]

yeah, figures

Set a breakpoint on that onZoomFactorChanged, go to Debug -> Blueprint Debugger or find it in tools, then run the game

when it drops you should see the execution stack

it'll prly show native C++ calling it at which point you'll know for sure

[subtle shoal]

Before I do that. I have to say that I have yet to simulate the game through the editor. My mods were so small that I just packed and ran each time I needed to test. Which option should I use?

[lunar sleet]

selected viewport

[faint pasture]

Select feeding into an FInterpToConstant

[dawn dragon]

@fiery swallow hi! are you still willing to help out

[inland walrus]

hey, this is on event tick, any idea why the progress bar isn't matching the health?

The set text works perfectly

[lunar sleet]

Define: "isn't matching"

also have you learned how to use breakpoints yet?

[inland walrus]

I don't believe so

[lunar sleet]

right, so it's the other way around. Your hp doesn't match the numbers

Your SetPercent is looking for a number between 0 and 1 not a number between 1 and 100. Divide by 100 before you plug it into the SetPercent.

[inland walrus]

Great thanks I'll try that now

Now that you point it out it seems so obvious lol I feel dumb

[lunar sleet]

Nah, everyone falls for that, I did too the first time around

[fiery swallow]

sure

[dawn dragon]

awesome! will you be available in 5 minutes?

[subtle shoal]

I don't think I have the resources for that. It's been loading since your reply and I'm at 29%.

[lunar sleet]

Oof

[dawn dragon]

if yout still down to call and looka t it we cacn join one of the VCs whenever your free

[subtle shoal]

Do I need to change a setting somwhere? I am well above the recommended system requirements for this game (it's 5 years old) so I should have any issues.

[lunar sleet]

Well depends how big the game is ig

[fiery swallow]

I can help you through parsec or teamviewer. I'm not into saying "click here, click there, do this, do that" lol, also check your dms. no need to talk here

[dawn dragon]

okay, id ont have any dms rn tho lol

[dawn dragon]

i just figured i could show you the code and stuff so you could see it better, or i could SS and send u, since oyu said you needed to see everythign

i just need a direction to go in bc i feel like ive tried just about everything i can think of

[fervent crypt]

Hey guys, is there a way to change editable text box when enter on android. when it pops up on android it set done but then it won't move on to next screen on mobile. or how would i change it to it can be used as enter.

[proud salmon]

Does anyone know if it is possible to use a blueprint to modify or create an actor and then save that actor to the world? Not at runtime, in the editor. In the same way I can just drag a new actor into the world and then save the level.

[dawn gazelle]

Do you mean having something programmatically place or modify actors in the current scene?

[proud salmon]

Correct

[dawn gazelle]

[jolly epoch]

how could i make this so it cancels if the mesh in unrendered again?

[lunar sleet]

Does the false pin fire when it’s been unrendered?

[jolly epoch]

i honestly have no idea what that even means, im still really new to coding

[lunar sleet]

Drag from the False pin of the branch, use a print string node. If it prints it fired

[jolly epoch]

yeah it does

i kind of want to make it though so that the delay is more of like a counter for staring at the thing for 2 seconds

[frosty heron]

Where r you from? First time I see someone with my name.

Btw what do you use the interface for? I rarely have use for it.

[jolly epoch]

so it dosent tp away if you look back before the delay is done

[jolly epoch]

To explain that better I want the code to be so if you are looking at it FOR 2 seconds it will tp away, not if you look at it and still are 2 seconds later

[frosty heron]

I don't think was component recently rendered is any use in practice. Pretty sure it's too unreliable for what you want to do.

I know what you want to do, but I don't think it will cut it

Anyway, you want to run a timer or accumulate float on tick

Where time = time + delta time

If >= 2.0f do something

Or if the bool works, ( which I'm pretty sure it doesn't) then you can try using retriggerable delay instead.

[chilly crane]

obviously this isn't going to work. I want to access the array "Widget Stack" that exists in another blueprint, to add elements to it here. This is for a UI, so I'm not sure what to put into the object node for the cast

[faint pasture]

what BPC Equipment System does this widget care about?

[chilly crane]

so the Equip system contains the code for handling the removal of widgets from the screen, as things like the Escape key can be used to go back on multiple widgets. However I need to know what widgets are currently active, so everytime a widget is opened, it needs to be added to the array

[faint pasture]

You should probably tell each widget about the equipment system instead of having it try to figure it out on its own

[jolly epoch]

what event would i connect to the timer? and how would i measure the time looked at the mesh if i dont use the rendered function?

[chilly crane]

and how should I do that?

I can't add the reference like I normally would with a player controller

[frosty heron]

If you want to just check if it's align with the camera you can do dot product, and some traces to see if anything block the line trace.

[crisp sandal]

what is the best way to let the cave teleporter know the location to the start teleporter?

wanna create a reference but seems like i can t

[jolly epoch]

so would the trace point checks have to be done in the player character?

[frosty heron]

You gotta work the logic first. Make sure it make sense to you

[faint pasture]

Add a scene component to that teleporter actor. Move the scene to where you want it to be in the world

[faint pasture]

And you don't want that code

That will teleport Player 0's character the split second ANYTHING overlaps

which is presumably not what you want

[crisp sandal]

yeah i know first part is for the plate 🙂 so it goes down slowly 🙂

[jolly epoch]

it def does not make sense to me rn lol. i might just have to leave out the random teleporting on the enemy it seems way to big brain for the amount of experience i have rn.

[faint pasture]

then why teleport them every frame while it's going down?

[frosty heron]

A pebble overlap with the collision and the player got teleported 🐱

[faint pasture]

teleport them when it finishes

[crisp sandal]

i just wanna use my other teleporter for this wich is the starter of and then i can later implement ui to choose wich one you want

[jolly epoch]

thx for trying to explain it to me tho

[frosty heron]

Well take your time. Learn dot product and some vector math. Then see how traces are used.

I don't think the code to check if something is in view is an easy problem to solve

Even with what I suggested it's not perfect and have draw back.

[timber knoll]

How can I knock back a character?
Launch is only applying the Z (I have everything set to override) even if I change the accelerations to 0 for a brief moment

[crisp sandal]

make a calculation for the vector and apply it and add the right animation 🙂

[timber knoll]

Not quite an answer to the question 😅

[crisp sandal]

i have it implemented but sure you do you 🙂

[timber knoll]

Never said you didn't, my question was rather why the other components of my vector aren't having the effect I'm trying to achieve

Even if I set the X and Y components to something like 50000

[faint pasture]

how much is the Z?

What happens if you launch with 1000, 1000, 1000

[timber knoll]

300

If I launch with some reasonable values it's pretty much only the Z being applied

[faint pasture]

Show a clip launching at 1000, 1000, 1000 with no inputs

do you have a lot of air friction or air control?

[timber knoll]

Hmm yeah with just a simple launch on non moving dummy it's as expected

[faint pasture]

with those settings as long as you're in the air you should fly like a projectile really

on the ground is another story, ground friction will slow you very quickly

[timber knoll]

Yeah that's what I figured and why I added a small Z to my knockback

The affected characters are airborn for quite some time, but not really flying as I'd expect 🤔

[faint pasture]

300 ain't much, its less than a jump

[timber knoll]

Maybe it's just visually because I'm literally teleporting around and should just test my logic in a stationary way

[faint pasture]

your jump is 420

[timber knoll]

https://medal.tv/games/unreal-engine/clips/j6NeL5Cdc2vsd7yjl

This is 1000 each

[faint pasture]

looks about right

that's 10m/sec

[timber knoll]

Okay lol on this stationary target I'm just yeeting it away

With my actual knockback ability

So it must be something with the movement breaking my launch

[faint pasture]

how are they doing the moving

[timber knoll]

AI MoveTo with the player as target 🤔

This would be expected result
https://medal.tv/games/unreal-engine/clips/j6NqBHuAng48CmVwq

Knockback with more force applied to the ones close, works fine with these values on stationary test dummy

Would just need to figure out what I need to change on the movement component to get this result on the other ones too

[faint pasture]

Does that go through CMC?

[timber knoll]

Stunning them for a short duration is no problem at all

[faint pasture]

I mean is the CMC/Character even walking really or does it bypass all that

It's probably at least navmesh walking which might be a different movement mode

Try have them just add movement input towards player character, so they're walkign the same way the PC does

[timber knoll]

Yeah that's a fair point, let me try

[timber knoll]

Aha yeah you're right

It's working as expected with just an add movement input

Thanks for the help 👍

[pseudo valley]

hey, i've been trying to implement a missile that flies in zero G using AddForce (forward vector * some amount as force).
Desired Velocity takes in a vector calculated using GetVelocity + VelocityChange (a vector that commands a change in velocity). In this function, it then calculates how it must rotate to reach that target velocity vector while mitigating momentum as much as possible.
The issue i'm facing is that when the velocity vector is nearly same as the desired one, it keeps rotating (like oscillating) in circles to stay on the path, instead of simply angling slightly, which means it cannot thrust forward any faster as it keeps rotating to cancel out its own thrust). Could it be because I thrust at the end instead of at the beginning of the sequence?

[runic parrot]

Has anyone noticed INSANE fps drops with 5.5? (From 5.4)

[inland walrus]

Does anyone know why when I ask an NPC to follow, only 1 NPC follows, no matter who I ask to follow it's always the same NPC

[runic parrot]

Probably your interaction UI is always targeting the same Pawn

Instead of "village" use the Display name of the actor and see what you are targeting there

[inland walrus]

Inside the widget?

[runic parrot]

yeah, where you are setting the text for "villager"

you most likely have an AActor reference inside that widget

[inland walrus]

It's always targeting the default

[runic parrot]

get display name of that actor and show it somewhere on that UI

[runic parrot]

that, check if the UI is targeting always the same one pawn

[eager thicket]

is there a way to ensure a timeline always finishes once it starts?

I've basically hooked a timeline up to a float value, but sometimes it will prematurely ends because of the nature of the float.

[inland walrus]

Instead of doing a ref to the villager should I try do a cast instead?

[runic parrot]

You have a "finished" pin

[runic parrot]

Okey, there is your problem.

The widget is always getting the same villager ("Get Actor of Class" will return you the first match)

where are you creating that UI (the widget)?

[inland walrus]

Okay okay, and in here

right that makes sense

[runic parrot]

Is this on the Character pawn or the villager?

oh nvm

get a ref to self and put it on "owning player" of the widget

or your "villager reference" make a exponse on spawn and plug your villager when you create the widget (Use this one)

[inland walrus]

It won't let me compile when I expose on spawn

[runic parrot]

What error do you get?

[runic parrot]

check this one

[inland walrus]

yep

[inland walrus]

"plug your villager when you create the widget (Use this one)" where should I plug the set villager ref?

[runic parrot]

2. Plug the villager to the variable when creating the UI
3. Remove the setter of the village variable "OnConstruct" on the Widget
4. When you are setting the name of the vilager on the Widget, do a "right click" on the villager ref and click "Convert to validated get"

here, refresh the node and you will get a variable "villager ref" below "owning player"

[inland walrus]

Step 2 like this?

[runic parrot]

yeah

[inland walrus]

step 3

[runic parrot]

remove that, you already have your village variable set

[inland walrus]

just the set? or the get actor too

[runic parrot]

both, you don't need to get the actor either

[inland walrus]

Alright

[runic parrot]

Your widget already knows what villager you are pointing to, you already passed it when creating the widget

get used to do 4) when you are using references, otherwise your game will have increased chances of crashing later if those variables are not set

[inland walrus]

Got you okay

[inland walrus]

and step 4 good?

[runic parrot]

yeah, that's it

[inland walrus]

Dude thank you so much

[runic parrot]

np

[inland walrus]

I've been trying to figure it out for hours, you're a life saver

[runic parrot]

This discord is a blessing, if you don't know something just come here and someone is going to help (given that you explain your problem correctly xD)

[inland walrus]

xD this discord has saved my ass a lot hahaha, it's also kept me motivated knowing that if I literally cant figure it out I don't need to give up

[livid flare]

Hi! I'm trying to figure out how to handle character collisions when on board on a moving vehicle like a bus, so he can walk around without messing up with the vehicle collisions/physics, any help?

[opaque acorn]

is there any option to render scene 2D in downsampled form ? or I need to use C++ for that

[spark steppe]

just decrease the resolution of your render target!?

[native canopy]

There is a way to call non thread safe functuon in tharde safe

[spark steppe]

there is not

if you are talking about AnimGraph methods, you can make them const (may even work for non-const methods), and when bound to a property they will be executed in the PreAnimTick to cache the data, but they will execute on the main thread

[native canopy]

In GASP 5.5 what happen if i disable thread safe

[spark steppe]

what is GASP?

[native canopy]

Game animation sample

A short title

[spark steppe]

🤷 you provide little to no context, so i have no idea what you are trying to do (or i'm just not getting it...)

[native canopy]

You know game animation sample tempalte in 5.5 right?

[spark steppe]

barely... guess it's the thing with the "500" animations?!

[native canopy]

https://www.unrealengine.com/en-US/blog/game-animation-sample this sampel using thread safe in blueprint, what happen if i disable that

[native canopy]

Yes

[spark steppe]

then you most likely wont get multithreaded animation updates

i don't know the example in detail

but the Animation system can run multi threaded when it can get it's data from thread safe functions (or under the circumstances noted above)

[native canopy]

Hhmm, there is an idea to use non thread safe function in this condition

Like 'GetSocketTransform'

[spark steppe]

depending on which mesh you want to get that transform from it's pretty much undefined behavior in a multi threaded animation update, as it could be the transform from the last frame OR the current frame

also this whole topic rather fits into #animation

[inland walrus]

Any flip flop alternatives? My flip flop is doing the same function twice when it starts before functioning as it should

[maiden wadi]

A FlipFlip is just a macro of a branch with an internal boolean. You're setting a boolean which looks like it should be picking your state right after the flipflop, so you could probably use your own branch instead as well.

[lunar sleet]

You should avoid flip flop anyways, beyond very basic prototyping, because you can get false positives depending on how and when it is called

[untold fossil]

Since when is this not possible anymore? I did this is my project pre-migration and it worked fine. Now it gives me this error on the exact same code? I also have no clue whatsoever it's complaining about? I can't set a datatable row from bluerpint? Why not?

Wait nvm, had to recompile the parent blueprint

[ocean current]

so Im doing a tutorial that during it they blend the upper and lower half of the body but it actually break other animations. i tried using the blend on bool but I don't know if i was doing it right is there a way to have it play one state then the other based off a bool or something else. here is my original and the changed to. The first pick is the one i want to branch

nevermind I figured out what i was doing wrong on the blend pose by bool

[latent basin]

Hey guys, Is Interface inheritance in ue blueprints a thing? Im trying to create a child blueprint from a BPI but the results are wanky and the child class does not appear in the implement interface menu. If it's not a thing, is there a better solution than normal Actor inheritance?

[lunar sleet]

It is a thing yes, inherited interfaces will show up under the respective category

[latent basin]

What do you mean? How do I create and implement them?

[lunar sleet]

…you create an interface, implement it in the parent and the child will inherit it

I just noticed the part about you creating child interfaces, no that’s not a thing, why would you even want that

They’re not objects

[latent basin]

I guess I just want to make a hierarchy of implementation structures without specifically assigning them to actors or such...

Also I don't need to add any variables or components to that hierarchy

But Ill do fine with plain class inheritance. Thanks a lot anyway!

[lunar sleet]

Mb for misreading the initial post and giving you false hope lol

[tulip bough]

Is there a numeric range type node?

I have this set up to play an animation based on the speed of the character falling. But right now its <=

I'd like to set it to a range of numbers. That way I can have multiple animations.

Is there some sort of "numeric range" node? I can't seem to find something similar

[paper gate]

A general question from a newbie. Is there a way to trigger an event when a variable's value has changed, preferably without having to check for its value each tick?

[thin panther]

No. Easiest way is just make a setter function. Sets the variable to whatever you need, then invokes the functionality afterwards

[dawn gazelle]

Closest thing I think you can do is a Compare Float node.... This then gives you >, = or < comparison.

[thin panther]

Sounds like you could use animation choosers for this though

That's an example from the patch notes using different damage ranges and strengths to choose a hit animation

[deep lagoon]

anyone know where i can find documentation on the Json Blueprint Utilities

[paper gate]

How would I do that?

[thin panther]

make a function

set the variable

do what you want after

instead of setting the variable directly, call that function

[paper gate]

Okay, I get it now. My brain didn't work for a second there. Thanks

[faint pasture]

in multiplayer (and I guess technically singleplayer in BP) you can use Repnotify

IDK why UPROPERTY doesn't just have an auto OnChanged delegate built into the system

[paper gate]

I found it quite strange, to be fair

It is what it is though

[inland walrus]

Sorry for the delay, thanks dude!

[tulip bough]

This looks like an interesting solution. Thanks

I feel kind of dumb. How do I add bitmask values in Blueprints? I have an int with a bitmask checked and linked to an enum. I'm trying to add bits with the Or operator but I'm getting incorrect values. I feel like I'm missing something simple

[twin shale]

I think I got it.

[faint pasture]

[inland walrus]

Any idea why my tick isn't getting passed "Do Once"?

[faint pasture]

No clue, the answer involves the rest of that function

do you know that reset is ever being called?

but what are you trying to do here?

you trying to do something every 0.2 seconds? Don't get tick involved

[inland walrus]

The tick is to check if the night is still active or not

[inland walrus]

This is on tick in the widget

This is working but I need it on true instead of false

but on true it doesn't work

[versed crypt]

quick question, do I need to cast to custom game mode to get its reference inside pawn/actors event graph everytime i need it... cause get game mode gives you base object reference and it doesnt work with my custom gamemodes variables/events etc... OR maybe i can cast to custom gamemode and hold its reference as variable or something in Event begin play and use it across event graph in any place i want without casting it everytime.

[wind rivet]

Yes you need to cast if you have a custom game mode and want to access any functions or variables you've defined there. holding a ref in a variable is a good idea

[versed crypt]

so can i hold it as varialbe and set this var in the "event begin play"?

[wind rivet]

yes

[versed crypt]

oh... theres choice, didnt knew that, still learning blueprints coming from c++, thanks

[floral stump]

begin play will cast it on Server/Client both
and when you want to use it everytime check for IsValid node and if not valid cast it again

[versed crypt]

hm, I suppose it can get messy if you have multiple gamemodes across project so IsValid node good idea, havent went into Server/Clieant part, probably thats another big topic to discover (multiplayer)

[floral stump]

you can make a helper function which returns a valid game mode

this way you don't need to write cast-> node and other things repeatedly

[versed crypt]

how would any pawn/etc... would reach such helper function (cause i dont think you mean adding this function to every blueprint) ?

[floral stump]

add this to the base blueprint and override in child classes

[versed crypt]

havent went into base blueprint logic, how would you override a base blueprints logic, you mean editing gamemodebase?

[floral stump]

nah, suppose you make a pawn class in your project, call it MyBasePawn. add functions to it
right click on this class and create a child actor, call it MyVehiclePawn, create another child of it call it MyCharacterPawn

now MyVehiclePawn and MyCharacterPawn can access anything which is existed in the MyBasePawn class

[versed crypt]

oh... havent thought you can do these kind of stuff in blueprints, blueprints for me looks very limiting but I guess its only to find out what it can do

[floral stump]

you can do 99% of C++ things in blueprints

just few things limited to c++ which is very advanced stuff and not everyone uses those things

[versed crypt]

Im kinda doing mashed potatoes, so its c++ and blueprints (cause it makes sense for me more in c++ than blueprints and some things looks easier in c++)

[floral stump]

easier and fast

but again it depends on task

like dealing with UMG in C++ you have to use slate

[versed crypt]

but i heard few games were fully made in blueprints and pretty big ones, but i heard if its true, blueprints arent really efficient so you go c++

[floral stump]

which is super fast in performance but takes 50x + time consuming compared to bp where you just in few clicks make an advanced UI

[versed crypt]

yeah, i looked at slate and said "hell nah aint got time for that" coding a c++ into UI 😄 but found bind c++ and blueprint kinda a good mix

[floral stump]

yes possible

yeah slate takes too much time

[versed crypt]

is UMG blueprint editor is advanced like blueprints, i havent deepdived into UI stuff but i wanted to make modern menu and it wasnt going so well, is editor for it limited and for some more advanced things you will only do it in Slate or no?

basically Slate vs UMG GUI editor

[floral stump]

nah you can do anything in UMG blueprint

but its hard to get some refs to C++ classes from UMG blueprint

you will have to base them from C++

and design in blueprints

[versed crypt]

yeah thats what I did, i based UMG from my C++ with binds

[floral stump]

this is more freedom

[versed crypt]

I guess i just need a good deepdive into UMG to understand how editor works

[floral stump]

you will explore it with time

or start something big with like a very big advanced UI project

[marsh sonnet]

Hey y'all! I think this is a simple fix: I want to launch character along an arc. I know how to make a curve... but not how to implement that curve. Can someone point me to a good tutorial, etc.? I can't find what I need

[versed crypt]

is github the only good source for UMG examples or is there good Epic games provided ones, I checked lightweight ones and it was just simple play button

[floral stump]

i guess you have to find tutorials for each task like
settings menu
player list menu
character slots menu
umg particle menu
inventory menu

and combine them in one UI

[versed crypt]

I checked Lyra project but UI was full of parent and child nodes in UI and they used CommonUI all over the place. Is CommonUI a new meta?

[floral stump]

and here the channel #umg is also a good source to learn

[maiden wadi]

Parent and child nodes?

[versed crypt]

i meant references not nodes heh

but thanks for tips 🙂

[maiden wadi]

CommonUI is a newer concept that fills a lot of holes that default UI implementations in Unreal don't solve for common games. It largely helps with gamepads, but some of it's stuff is really useful even for Mouse/KB only.

[versed crypt]

so if my first project to touchscreens, not really worth it unless for self learning?

[maiden wadi]

I've never really done Mobile personally, but I don't think it'll do a ton there outside of allowing you to switch control modes if you make your game touch and mouse or gamepad. But I imagine I would probably still use it. It's button class is far superior to the default UButton and activatable widgets are still nice. I also heavily use CommonGame which is a plugin in Lyra as well that allows generic pushing of menus to defined layers, which uses CommonUI's stack widget.

All in all, I'd probably still use it for mobile, just because of a couple things that I'd end up implementing myself. But it is a learning curve. Some people find it steep, some people find it "overengineered", but then they turn around every other day and complain about not having something it would help them with. 🤷‍♂️

[versed crypt]

hm, can you give one example of what CommonUI can do what normal cant? Something that is found in many current games and is often used

[maiden wadi]

Global escape key that backs out of menus without having to implement it in every single menu or maintain it in a Parent of your menus.

CommonButtonBase's OnClick callback returns the button. So you can register an array of buttons for the same OnClick handler, and switch on the button pressed easier.

Using Widget Stacks, you get cached reusable menus that don't have costly creation code or major garbage collection. Which you would have to maintain yourself without them, and all you have to do is simply add the menu to the stack container, nothing extra.

Most multi control games have differences for touch, mouse, and gamepad. CommonUI tracks the latest input and has a callback for when input mode changes.

Activatable widgets manage your InputMode (Game, UIOnly, GameAndUI), so that you don't have to maintain a state machine or have crappy switch cases to pick the right input mode when backing out of or adding new menus. It's tied directly to the ActivatableWidget that is foremost on screen.

Platform specific input icons, both for gamepad and KB/mouse

Auto focus restore for gamepads, so when you switch to gamepad from KBmouse, or you open a menu or go back to some other menu it'll automatically make sure a correct widget is focused for your gamepad navigation.

[versed crypt]

it seems that it doesnt really add anything new and groundbracking as in new UI stuff, but its just easier to maintain as you dont need to add same logic to lots of items etc?

[maiden wadi]

There are some new widgets, the button class which also doubles as an easier stylable checkbox. The attachment container allows you to attach a child to something without requesting more than a pixel of space so that it doesn't make it's parent's size larger even if it is. There are a few new containers that solve issues.

But no they don't really add new widgets a ton as much as fix a lot of handling ideas around them.

Realistically I wouldn't make a project without it again. I've went from default UMG in a released project and converted it to CommonUI. And I've had to work on projects that don't use CommonUI after that and it feels like hell.

[faint pasture]

Just don't use UI

[fading garden]

Can anyone explain to me why this isn't changing to the gold version?

[dawn gazelle]

Gold = Implementable Event, Grey = Function

[fading garden]

Yea it's supposed to be an interface that I implemented. I think

[dawn gazelle]

It would only be an implementable event if it did not have a return value. Because it has a return value, it is a function of the interface..

[fading garden]

Hmmmm

This is what I get for looking for a simpler tutorial.

I think I need to go back a video or 2. Thanks for the help

[quartz tapir]

Hey guys - I'm working on a system where as the player move around, nearby objects in the direction the camera is facing are highlighted (to eventually be interacted with/start combat). I wrote this and it works but for some reason I feel like this is a complex function for what I'm trying to do. Guess I'm just looking for reassurance there isn't a simpler way to do what I'm doing (this function is running on tick btw) https://blueprintue.com/blueprint/dimrvt6f/

[fervent crypt]

Hey guys, is there a way to change editable text box when enter on android. when it pops up on android it set done but then it won't move on to next screen on mobile. or how would i change it to it can be used as enter.

[hoary nest]

Finland 😂
I am making the interface for actors that my user can create (kinda like a CAD software). Not sure if the interface will come in handy, but it might since I'm making json serialization functions into it now.

[dawn gazelle]

It looks ok, the only thing I'm not sure about.... Is this running on the server, and then you're RPCing to the client to tell it turn the outline on and off?

[quartz tapir]

Heh that bit is from a fab resource I'm using to prototype. This would be a SP game regardless.

[dawn gazelle]

Ah ok. Then yea, it looks like it's fine for what it's supposed to do.

[quartz tapir]

Danke

[wicked cairn]

OH! That would probably be very helpful! I’m a little frustrated because last time I messed with the plugin, you couldn’t run the wfc during runtime 😭 and I’m trying to make a dungeon system that can do that so I was hoping in 5.5 they finally touched the plugin again lol

[hushed fox]

You need to enable root motion on the animation montage, it’s a setting

Root motion moves the capsule with the animation

[faint pasture]

https://www.youtube.com/watch?v=guIauFrpe7s

It's not ready for primetime and will ONLY be for generating the raw WFC data but it's for dungeon/map generation using the overlapping model

[hushed fox]

I recommend watching a tutorial on YouTube for root motion, it has a couple settings that need to be set for it to work.

[wicked cairn]

WHAAATT THIS LOOKS SO COOL??? I can't wait to see the finished product!

I think what I'm going to try to do for now is mess with the plugin code and make it so I can call the collapse function during runtime, I've already made some assets and a model for generating a test example 😭

[faint pasture]

I have no idea how the PCG stuff works but I think it's not the overlapping model

What I like about overlapping is being able to hand make example maps

[wicked cairn]

I forgot to ask but what do you mean by the overlapping model?

[faint pasture]

https://github.com/mxgmn/WaveFunctionCollapse

[wicked cairn]

OOHH this

gotcha thank you!

Hi. I have been trying to make a space ship in VR and am using 2 levers to rotate it but when I do rotate the ship the levers are a child of the lever script breaks. More specifically the rotation of the lever. This is the script to rotate the lever at the moment.

[idle vigil]

when looping through an array of structs, if i remove some of the structs as its looping does it mess up the loop or is it smart enough to handle that?

[gentle urchin]

its not smart enough

by itself

never remove elements in a forward moving loop

[idle vigil]

ok ill just keep tab of which structs ill remove from the array and then do remove item after the loop is complete

[gentle urchin]

or ReverseLoop

[idle vigil]

oh yeah that works too thanks

[faint pasture]

why do you have a 100hz timer

where did you get the idea of a timer that fast from? I'm genuinely curious, I've seen a lot of newer people doing that and I bet it all comes from one video or one content creator person

[marble brook]

How can I change the text of a ui widget element at runtime?

[gentle urchin]

SetText for textblocks

expose them as variables, if not already

read the thing you want to read on a delegate bound up in the widget

[marble brook]

Im trying to do that but I can't seem to get it to work

I've set the text block as "Is Variable"

[gentle urchin]

now whenever my Healthchanged is called, i get the update in the UI

[marble brook]

My problem seems to be actually gettng that text box to set the text of it

I understand checking "Is Variable" on the text block

but I can't seem to get a reference to it

[gentle urchin]

drag from the variable (which is names the same as in your widget editor)

and search for SetText

only works if the underlying type is correct ofcourse

so if you've selected a "border" as a variable, it will not have text properties

[marble brook]

Do I have to do this in the blueprint for that widget?

[gentle urchin]

That's the smart place for this logic to be

[marble brook]

👍

I figured it out then

Thank you 🙏

[analog heart]

almost all of the the vr lever tutorials on yt that don't use tick do it that way 😅

[gentle urchin]

they're mostly wrong then

😄

[kind estuary]

The save game system is better done at the end of your project, right?

so you completed your game, and then you had the save game functionality

so that you can save all the variables and everything

[gentle urchin]

atleast then you know the actual scope of your variables

using something like ESG should trivialize that part

[kind estuary]

🫡

thank you senpai

[kind estuary]

ESG ? never heard of it

was googling

u mean EGS

[gentle urchin]

easy savegame or smth

EMS*

Easy multi save

https://www.fab.com/listings/49f745a1-cbdd-4b18-8278-22ae1075d91d

[faint pasture]

They are 100% wrong.
When do you want the lever to change its rotation?

It makes sense that you'd want it to be at the latest correct rotation every frame right?

[kind estuary]

though 💰💰

https://tenor.com/view/cat-cattitude-fun-cat-cat-fun-cat-funny-gif-5683118938279006051

[gentle urchin]

It was free a while ago

not sure what the price is now

[analog heart]

Whenever it is being held

[gentle urchin]

but according to 'rumors'

its gods gift to developers

[kind estuary]

yeah it looks like it makes it so easy

though i prefer to suffer and learn to do it by myself

[analog heart]

yes

[faint pasture]

That's tick

Tick is the thing that runs every frame. Put per-frame logic there.

[analog heart]

Aight'

[shy matrix]

You can check out SPUD. It's free and quite robust. For some reason I can't post github links here but you can find it with a simple search

[gentle urchin]

Oh yeah that's the other one

people seem to like

Hi guys, recently i noticed a big problem with skeletal meshes exported to ue5 from blender, for some reason the exporting makes it so that the rootbone of a skeletal mesh is sized 100x, does anyone has a solution for fixing it? I tried 1 method in blender which requires me to apply armature in the mesh, but i cant do it since i have shape keys.

[empty hare]

Anybody know if im able to set it up so when packed and in game im able to record a 2d scene capture from a keybind

and save it somewhere as an accessible file

[eager meteor]

Need some assistance. I am using an "Actor" reference that is set through an interface into another Actor. I want to get a bool within a certain BP that is of the "Actor" Class. When I try to get said bool it gives me an error because the Target is obviously just an Actor and not a direct cast to the Actor that has this bool. How do I get a bool of an specific actor via an interface WITHOUT using a Direct variable for it.

[marble brook]

I notice stuff like Apply Damage, Point Damage, Radial and Radial with Falloff, does this imply there is a health system already in place or do I still have to make my own? If there is one already in place how do I get this health value

[kind estuary]

thanks bruh thats a great tip

i really dont like setting save game

so many variables and shit that i can miss

[dawn gazelle]

The variable type defines what is stored and what is accessible from the variable, but only at the level of that class - sub classes of that type will not allow you to access their variables and functions until you cast the reference which then gives you a reference to that class which you can use to access those variables and functions. If you don't want to cast or utilize a variable of the appropriate type that has access to the variables, an interface that returns values is the only other option you have.

[dawn gazelle]

It is just a generic set of functions built into the actor class that you can implement as you see fit. On the receiving actor classes you'd implement "Any Damage" for example and then you can define what happens when damage is received.

[shy matrix]

It's a very old and common problem. The only trick I could rely on is this

https://forums.unrealengine.com/t/tutorial-skeletal-mesh-blender-to-unreal-engine-scale-and-bone-rotation/1414234

But, if you are on recent engine versions, to save you headaches, I'd recommend you to add bones in-editor

Then you can still export the fbx to further edit in blender where needed

[shy matrix]

There is none. This is a built in actor interface to move damage values around with the added bonus that it already handles impact physics for you, if you want.

Well it's technically not an interface

Hello, house, please anybody have idea about unreal engine 5.5 pixel streaming

[tulip bough]

How would I go about changing the camera position based on the direction the character is facing?

Currently have a 2.5D setup, and would like the camera to be a little ahead of the player (in the direction they are facing)

[lunar sleet]

Use controller rotation checkboxes on the camera

May need to have said camera on the char as a component
