blueprint

[trim matrix]

how can i change the shadow from the dynamic one the player mesh casts to a simple circle like how player shadows were done in sm64?

[thin panther]

disable the shadow and use a fake one.

Those sorts of shadows in old games aren't shadows at all

[trim matrix]

ik. but how would i go ab doing it in unreal? i already have the dynamic shadow disabled

[surreal peak]

I decal I guess.

[dreamy yacht]

Hey pls help me because I can't figure it out on my own. I need some old / classic Death Rally based powerup behaviour, where powerup shows up for 21 seconds, then the powerup image ( billboard ) starts to flicker for 7 seconds and then dissapears if not collected by actor within that time. When an actor picks the power up, the powerup doesn;t get destroyed and removed from level, but gets hidden for 10 seconds

And then respawns ( it's still there but the overlap behaviour is disabled for the cooldown duration )

I can't freakin figure it out

Because I guess the respawn logic has to be driven by the code "set timer by function name or so "

This is working respawn logic, but it's old and doesn't take flickering effect into account.
21 seconds pass - main billboard gets hidden
7 seconds pass - flickering material based billboard shows up and gets hidden after 7 seconds
everything is hidden until next 10 seconds pass ( respawn cooldown ), the overlap reaction is turned off
until cooldown is finished
not collected - everything is
visible

Slowing down the character gradually over time. The character slows down significantly over a period of 0.05 seconds. This is for initial wall running contact. It roughly mimics euler formula. It is very smooth. Roast me, I got time learn how to not be stupid.

• Custom Event fire when player touches wall
• Player is slowed over time.

[hollow prawn]

cant you just use a curve?

[crystal ridge]

A wat?

[shy matrix]

All those delay in a sequence are calling for this to misbehave. Better applying a force or modifying velocity on tick or timeline

[scarlet root]

Can someone explain me, how to prevent wrong rotation when a SplineMesh has a looping?

[crystal ridge]

How would you slow down the character over a period of time easing into it?

[shy matrix]

As said: over tick or timeline you want to reduce velocity

You can do that directly subtracting velocity during the ticking time or accumulating a negative force

[crystal ridge]

I don't understand. Do you mean a gameplay tick? I need to do it over time inrespective of the game

[shy matrix]

Oh you want it framerate independent

You can set a timer

Maybe there's better way for that though but not sure why you need it like that?

[crystal ridge]

Yeah, I didn't want to pair this with the frames of gameplay but time itself

I did try to use a timer but I couldn't get it to work.

[shy matrix]

There is a way to use substepping but I have never used it myself. Maybe worth looking into that

[crystal ridge]

Sub stepping doesn't working in UE5... Oh well.

[barren tangle]

Hey is it correct if i say :
Triggered = Started + OnGoing + Completed?

what do they mean by :

how can you cancel without completed the trigger?

[shy matrix]

But timer should work. I'm not sure it's a proper solution but...that is by definition independent of tick

[crystal ridge]

Do you have an example? I would love try a few more things with a timer if I had a bit of guidance on it utlization.

[dusky cobalt]

Set timer by event, loop, timer 0.02. On the 'Event' you plug, you add Vector by x amount. You also need Duration and Current Duration to ''stop'' the timer when it reaches full. If you want for it to last 1s, your Duration is 1s, when Current Duration reaches Duration, you clear the timer and set Current Duration to 0. Each ''tick'' you have to add 0.02 (can be promoted to variable).

[crystal ridge]

I remember struggling to use that node, I guess it is worth more struggle. I will struggle for a bit longer today. Thank you both.

[dusky cobalt]

Just imagine it's tick on demand.

[dreamy yacht]

Anyone ?

[kind estuary]

Whats the difference between these 2 bad boys 🐈 . They seem to accomplish the same thing.

[minor mortar]

If I'm storing a DateTimeStruct in my level blueprint, should I make an interface for the level blueprint in order to modify those values, or is there a more straightforward way of accessing that variable?

[dusky cobalt]

just cast to it, no point in using interface for level blueprint

[split dagger]

I don't know the differences but here's all the info on them: https://dev.epicgames.com/documentation/en-us/unreal-engine/BlueprintAPI/Physics?application_version=5.4

[shut lantern]

Hello, I'm Having issues with my player menu blueprint where pressing tab should bring up an equipment screen and Q and E are used to navigate to other pages. Currently when pressing tab the menu doesn't show. I am very new to this, and could not find tutorials based on the exact feature I wanted and have been piecing it together slowly from what I've learned so far, so any help would be great.

[wanton sedge]

Not rly Blueprint, more like UI, but someone got a quick solution for this? I selected "Size to content" for the container, which is a scrollbox (the text right in picture) which works good up until the point where I have 2 different lengths of texts for my options. How can I make the button with less text scale not as much as the button with more text?

[wanton sedge]

From what I can see in your screenshots, you're not adding the Widget to the player's viewport. Could be that you're doing that somewhere else though?

[shut lantern]

I don't think I did, there's a good chance I missed that. I did something similar with my health/stamina/magic, I'm assuming it would have to be called on this event graph since I'm already using my health one on BP_ThirdPersonCharacter right? Figured it out, thanks.

[dusky cobalt]

Fill it Horizontaly

[unreal island]

Does anyone know why this wouldn't be working?

I have my AI set to move to the player when they are not "within combat range" (determined by a sphere collider outside the enemy). If the player is outside this sphere, the enemy shoudl find the players location and move to it

Is there something wrong with my code here?

[mystic blade]

trying to launch a character like a pogostick. short distance forward. long distance up

no matter the values i put in the multiply node, going up doest work

[civic oar]

Can anyone tell me why my character is almost like elastically attached to the socket on the vehicle pawn, bouncing up and down when going over bumps?

[civic oar]

I'm a noob, but shouldn't that multiply node be an add node?

[mystic blade]

that did the trick alright

i got the solution from some random unreal engine forum post

im dog ass at math

[civic oar]

XD

[mystic blade]

kinda

theres also the problem of pressing space again in the air to get a double jump which is not intended. double jump disables jumping altogether

ok kinda fixed that

[ancient siren]

why is this widget offset? ive researched and tried everything, just not sure what the problem is

[granite frost]

Thats a plugin called "flat nodes"

[next hollow]

Turn off player viewport relative
Its what I do.

All I do

Convert, and project do the same exact thing BTW, so no reason to switch nodes.
But, there is no reason for that viewport scale stuff.

[scarlet root]

Good morning.

Anyone?: #blueprint message

[hard sinew]

why is this happening

[lime tide]

Hello, i have a quite difficult question.
im relatively new and idk how to approach this:
tldr; monte carlo neutron simulation

I want to "Simulate" neutrons in a reactor by distributing points in the reactor, moving the "neutrons" to a random position and get which component its on: e.g. if its on a fuel rod, it adds 3 new neutrons, for control rods it deletes the neutron

Does anyone know how to approach this?

[gleaming island]

Goodmorning all ... anyone happen to know how the heck I am supposed to get the world object reference into a widget blueprint ?
I am trying to get the current state of a data layer (unloaded, loaded, activated) and it's getting the better of me.
From Data Layer Subsystem, I can only SET states. There is a Data Layer Manager node from which I can Get Data Layer Instance Runtime State , but it needs a World Object reference.

[frosty heron]

World context object or world object reference? Show screen shoot

[gleaming island]

sure, give me a second as Unreal just crashed

Some more context in the meanwhile, I have a Data Layer called Truck, and I want to toggle it's Loaded/Activated state with a button from my Widget Blueprint UI

but any other way to get / set the state of a Data Layer (as long as it's in Blueprint) is fine (if I am doing it wrong, currently)

[frosty heron]

@gleaming island world ref is not exposed to bp out of the box.

I would check for example on how to implement w.e you are trying to do. What does epic doc has to say about it?

[dark drum]

I'm pretty sure 'get world' returns the world obj.

[frosty heron]

Ye but not blueprintable right?

[dark drum]

I might be thinking of get level. 😅

[frosty heron]

World is level

[solemn shale]

My ping value returns 0 all the time. How can i fix that? Score and player name is correctly working

[frosty heron]

I don't know about getting a hard ref to a level too. Sounds cursed as f.

[frosty heron]

In lobby or in game?

[dark drum]

Are you testing on the same machine? No latency if it doesn't need to cross the internet. 😉

[solemn shale]

in game, print string debug in playerstate shows the latency around 10 - 16 ms but i can't get the value in the second pic. it returns 0

[frosty heron]

And when do you update the ping on the 2nd pic?

[solemn shale]

im testing on listen server

[frosty heron]

You might be running it once and too early.

Why are you storing them in a struct?

Just get the ping when you want to access it.

[solemn shale]

to show in scoreboard

[frosty heron]

Have your scoreboard attempt to update ping every X seconds.

You might be getting the ping way too early, I dunno.

[solemn shale]

this might be right but im waiting 5-10 seconds to see if it gets the correct value or not

[frosty heron]

Why do you have to wait that long

[solemn shale]

and im setting in widget bp

[frosty heron]

But you are just updating that struct once?

Wouldn't update for anything

Every X seconds, get player state , get ping in ms. That's the value you want to use to update.

[solemn shale]

oh i think you ask the right question

im updating everytime player joins

i think i should more often

update*

[frosty heron]

Yeah and you might be calling that get ping in ms when it's too early and still 0

Perhaps you can just pass a reference to your user display widget. The ref to the player state.

And from there get the corresponding player state every X seconds and get the ping

[solemn shale]

im also updating scoreboard everytime i get score. it update the ping value when i get score

[frosty heron]

I wouldn't wait to update ping only when the player scored.

[solemn shale]

good idea thanks

[frosty heron]

it should be contained to it's own logic.

[keen robin]

why I do not have async load asset?

[dark drum]

They can only be placed in the main event graph with it being a latent node. (The thing calling it also needs world context, just in case you're using custom uobjects)

[keen robin]

ah ok, now it explains everything

[livid flare]

Hi how can be set the run input to keep pressing a button to sprint, like GTA
I only found this in C++
https://community.gamedev.tv/t/how-to-speed-up-character-by-tapping-a-button/159037/3

[dusky cobalt]

On click increase movement speed, set timer by event, set timer by event after 1/2s will reduce movement speed to the default one. Every time you click it refreshes the movement speed boost.

If you need it to slow down in time, then you need to activate another timer by event that will lower the speed over time(10movement speed every 0.1s for example)

[livid flare]

Hey thank you! I'm gonna try this out

[dark drum]

Something like this would probally work. (not actually tested)

[frosty heron]

no experience here but suprised if Enhanced input doesn't come with something that you can use on Triggered

[dark drum]

It does but they want it where each tap increases the max walk speed a little until it reaches the desired max walk speed.

[frosty heron]

oh

is this like the old GTA 😄

I don't remember having such mechanic in GTA V

[dark drum]

San Andreas lol. (The most iconic of the series. 😄 )

@livid flare Needed to store the timers so this is a revised version. (Tested)

I wonder if I can do a GAS version. 🤔

[dark drum]

A GAS version if that's something you're into.

All the functions used are the same as the events in previous image. This is just the setup for triggering them when the ability is first activated and if it's then triggered again (via a gameplay event) if it's already active. It'll probally need some tweaks if you want it to consume stamina but might be a helpful starting point.

Oh, one minor tweak would be to check if the character is falling. This way we can avoid changing the max walk speed mid air. (I think it looks weird)

[oak juniper]

whats the best way to make object 3 invisible in an area that is created by object 1 and 2 overlap in screenspace? (object 1 and 2 are in random position, not nesesseraly in front or behind of object 3)
ive seen one solution based on the target that you calculate an angle to from the camera, but i want my overlap to be more intuitively adjustable, and have a custom shape.

i want to basically make a mw2019 scope but with more scifi shapes.

[scarlet root]

When doing SplineMeshes for a rollercoaster like track, Unreal does support ALL staticMeshes, but only Non-Nanite meshes can actually bend along the spline.
Does one know when this is possible or how to workaround that?

[livid flare]

hey @dark drum Thanks a lot man! I'm gonna try it rn

[frosty heron]

Anyone work with wind before? is the force always global?

[languid pendant]

Hello I have an issue with attaching an actor to a component on the player character. The first time it works perfectly but once I drop it and pick it up again instead of going to the position of the component it goes to the same place just like idk -50 underneath it. Does anybody know what could be causing this?

[livid flare]

@dark drum I'm in stage two checking why isn't working, I used 100 as Speed increment and not sure about the alpha value, currently when it reach max speed it won't decelerate when I release the key

[frosty heron]

if you simulate physic to a component, it will detach from it;'s root.

[languid pendant]

I tried doing this but it doesn't seem to fix it

[dark drum]

The speed alpha goes from 0 - 1 one so you're increase and decrease values should be less than one. I used 0.1 for increase and 0.01 for decrease in my testing.

How can I get the pitch value from the controller to go from -90 to 90 instead of 270 to 90. Having a blank moment. o.O

[dark drum]

I got it.

[livid flare]

Still not decreasing.. sure I missed something, I'm having a blank moment too 😄 I'll double check what I did wrong

[frosty heron]

Map range clamped?

[dark drum]

Share how you set it up. 🙂

[dark drum]

I got it it. Need to add 90, mod 180 and then subtract 90.

[balmy trail]

Anyone know what could be causing this error? I've been stuck on this for a few days now, maybe there's something basic I'm not understanding?

[merry mirage]

Hoi! Does anyone have any good resources on how to apply custom gravity onto non-Character actors? Is there such a thing, or would we have to apply force each tick to "simulate" additional gravity?

[dusky cobalt]

Just set timer by event and each tick increase gravity. By tick I mean the timer tick you set up yourself (how often you want it to update). If you want it to stop just clear timer.

[merry mirage]

I was specifically asking if anybody knew of another solution though, but I appreciate it :b

[pale obsidian]

Is there a way to prevent my bloated struct from displaying variables so literally?

Struct = (bool + struct(3 floats) x 4)

[dry sleet]

I would not use Unreal's collision for this.

It seems like you'll sum up to quite a few 'neutrons' and actual UE collision checking adds quite a bit over overhead.

Although... I guess it's fine as long as you just treat the neurons as points.

[solemn helm]

Im gonna throw this back out here. Looking for help with this issue, getting desperate haha. Not getting any responses on forums post is making me sweat: Unreal Post

[surreal peak]

I don't think that's usually a good sign if the starts expanding the Struct name.
Blueprint structs have often corrupted in the past, so be careful :P
Source Control and C++ Structs are your friends.

[surreal peak]

Well did you enable SimulatePhysics on the MeshComp?

[copper chasm]

I know this is more design related, but I like the answers I get here the best and it’s tangential re: actor components

I’m building the character for my Pathfinder based RPG, and I want to make sure the structure makes sense. I started with one big component for everything (the entire character sheet), but slowly realized there were certain things I needed to reference more often than others and it got spaghetti’d, so I’m refactoring.

What are the downsides to using different actor components for slightly related things on the same actor? Like, stats will not change nearly as often as hp or inventory, but hp max is reliant on a stat and the inventory may impact stats, etc

(sorry for wall of text)

[solemn helm]

This should do it should it not?

[surreal peak]

What makes you think that?

[solemn helm]

An assumption, based on the title that says SetAllBodiesBelowSimulatePhysics.

which I dont think is misplaced

[surreal peak]

Hm, I know that the SkeletalMeshComponent itself overrides SetSimulatePhysics.

And that that call already does what you are doing there. + a bit more.

So I would suggest you call that too or only that.

Specifically his only calls for Bodies

While SetSimulatePhysics also does things to the main BodyInstance

Not sure they contain oneanother.

[tired hollow]

Hey guys, I'm trying to replicate smooth but yet slow flashlight movement, but I thought this would work but it doesn't. How can I do this?

[maiden wadi]

I personally always think it's best to simplify this down into systems. GAS is a good example here maybe. It has an AbilitySystemComponent. The Component itself manages like your applied buffs, granted abilities and such and gives you a window to affect those things like activating abilities, or applying buffs. It also maintains AttributeSet subobjects that hold stats the buffs can affect.

If you weren't using GAS, I could see maybe making special components for related attributes if they make sense to group. EG Health, MaxHealth, HealthCap. Or MovementSpeed, MovementSpeedMultiplier. Etc. But I'm not sure I would advise putting the handling for those things there.

GAS does this kind of nicely where everything is picked based on the buffs applied and it tells the attribute set what value it wants to set. And the attribute set can allow or overwrite it. An example with Health. You're at 450 health. Your max is 500. You get healed for 200. The AbilitySystem simply tells the attribute set that it wants to set health to 650 now. That's all it cares about. But the attribute set gets to set the rules that health cannot exceed max health. So it takes in that 650, clamps it to 500, and only allows it to be set to 500.

You could mimic this with components I think. Where you have a primary component that accepts buffs, either instant or with duration, and tries to set values on your attribute components. And then your attribute components are more or less free to be bound in UI or elsewhere for gameplay effects. EG a healthbar can just listen to an actor's HealthAttributeComponent's delegate for OnHealthChanged, etc.

[dreamy mountain]

hey, trying to make a panel for arcade machine, when you press a certain button, the corresponding button on the machine presses
it currently doesnt do that, im using tags on a child actor to do that, but it isnt working

it prints nothing for the tags

[maiden wadi]

You need interpolation between current and target values.

[tired hollow]

Okay so timeline I guess

[maiden wadi]

No. Interpolation.

[faint pasture]

You aren't going to be diffing shapes like this, but what are you actually after here? Show a render of something similar

[maiden wadi]

FInterpTo

[tired hollow]

Doesn't work

It just rotates off screen

[maiden wadi]

For starts, ControlRotation is in world space, not relative. And you don't have the Target for Pitch hooked up.

[solemn helm]

I tried implementing this and got the same result.

[surreal peak]

If the skeletal mesh has physics enabled it shouldn't print the warning. I would suggest you check where the warning is printed in c++ and potentially breakpoint that to see what's going on

[dark drum]

🤔 Not sure, it looks right to me.

[livid flare]

Did you set something inside the input actions? Perhaps I have something interfering, I'll give a try on a fresh project

[trim matrix]

hey, not sure if this should be in here or in #enhanced-input-system but, how can i make my character's walk speed change depending on how far they have the stick titled? like have it be if a player uses a controller they tilt the stick the whole way to run and just a little to walk. but then keep the shift input for keyboard controls for running

[digital glacier]

how do i know whether im approaching/making blueprints the best way there, such as making it less cluttered or more optimized

[dark drum]

No, just a standard bool IA.

[livid flare]

I tried on a fresh pj and nothing changed, I'll keep you updated If I make it works thanks ❤️

[dark drum]

It's hard to say. Depends what you're doing.

[dark drum]

You might need to play with the BP in the background so you can see what's happening.

[dusky cobalt]

If they look nice, it's probably already good :D. Use comments. Separate logic for each step with comments. Use colors. Use functions for repeated code. Don't cross connect variables. Just make sure your code is easy to understand, keep the naming convention and just be consistent with standards that you set for yourself. There are general good practices for unreal, each team can have their own practices as well. But the questions is very general and would require probably listing like 50 things andsome of these can be personal (everyone does something on their own and it's not wrong if they are consistent etc.).
Avoid loop into loop in blueprints, these can get heavy (not saying you cannot use loop AFTER loop (on completed) but rather to not For Each into For Each etc.

[digital glacier]

thank you 🙂

really helpful

[dusky cobalt]

Also you can always post your code and let us judge it

[faint python]

In my animation blueprint off the event BeginPlay() node I was grabbing my custom character movement component but if I don't delay it a couple seconds it's invalid. Where would be a better place to get this?
Edit: Dumb fix my bad: #blueprint message

[dark drum]

https://tenor.com/view/minion-judge-gif-26165838

[dark drum]

There should be an ininitalized type event. On Animation Initialized (can't remember the name).

[livid flare]

looking good when debugging, I mean I see all the event properly fired

[faint python]

Ahh saw that one but In my head I read it as something else completely misunderstanding it haha. Thanks! I will move it there.
Edit: Dumb fix my bad: #blueprint message

[faint python]

So I threw it on there but still have the same problem where its not valid, but if I throw it in tick its invalid once then next time it is valid. Any other places I could get it? I don't love getting it in Tick aha.
Edit: Dumb fix my bad: #blueprint message

[faint python]

Figured out problem. I created a custom character movement component and set it as the default character move comp on character class. Then I also added a UBBMoveComp* property which I set to the character's move component in its BeginPlay(). This was causing it to not be set before the anim BP ran it. Removed property and just casted character movement component to my class and it works now. Dumb mistake my bad.

[celest trench]

In BP data assets is it possible to expose parameters only when a condition is met? For example make it so that I need to enable a toggle on a bool before seeing an option to select an enum? Or like a new dropdown list appears if the bool is enabled?

Or does it just have to always show every available option no matter what? It just feels messy

[worthy tendon]

it is possible in c++, not in BP afaik. pretty easy to do in c++ too. (just EditCondition and EditConditionHides meta properties)

[celest trench]

Thank you for the info 😄
So I could inherit from the C++ and it would work in BP visually to hide when I check/uncheck? I don't mind making the base class if that is possible!

[dry socket]

Hey all. I'm modifying the 3rd person template character into a dolphin, and struggling with the Character Movement component. The screenshotted script works as expected, but when I jump out of the water and switch my Movement Mode to "Falling", my player controller pitch (Y rotation, nose up/down) snaps to horizontal. When I fall back into the water, it snaps back to previous orientation.

It seems like both Falling and Walking states lock pitch at 0, but I can't find anywhere to change that.

[worthy tendon]

yes, i know two ways.
1- make the whole data asset in c++ inherit UDataAsset. with this approach you can't modify or inherit data asset from blueprint.
2- more flexible way is to make a simple c++ struct, then make a blueprint inheriting PrimaryDataAsset, in the blueprint add that c++ blueprintable struct variable. then you can create data asset of that blueprint type.

[celest trench]

Awesome thank you so much!

[worthy tendon]

there is a tool to quickly make the c++ struct too. then you can modify it.

[mystic blade]

cant figure out how i can prevent the player from pressing space again while in mid air. my current solution of using a boolean to check doesnt seem to be doing anything

unless im using isFalling wrong

unless theres a better way to disable a single key input

[dusky cobalt]

i mean this event doesnt last long after you click it, and also you are checking if its failing and it might work at 3rd click of the input key if you are lucky, because 2nd jump will launch character, then set it to cant launch and 3rd jump wont actually work

just check if its falling at the start

if its not = let jump

if its failing dont do anything

[mystic blade]

that did it alright

thanks homie

i figured my solution was absolutely dumb as hell

theres always an easier fix

[solemn helm]

I got a pretty general question maybe someone here can give me a solid example of how to fix. So I have a melee fighting game, and its online multiplayer, im running collision calculations from the server, and multicasting the hits to the client, its all working fine. EXCEPT one issue, the client very visibly slightly lags behind(Which is something I expect is common just due to the nature of networking), my question is, is how to fix it?

Im running my windup and followthrough attack animations directly on the client and server at the same time, so that the client has a more seamless feeling for when they interact with a character(rather than having to wait on RepNotifies/multicasts).

[frosty heron]

Multicasting the hit?

Multicast only have a place for the special effect for damage.

Everything else don't need RPC

And aside from that. Get familiar with latency and round trip time.

Damage is server only so for client the attack came from the future.

So server have to allow some windows for client to respond.

How long is the Windows is up to you and your game feel.

I'm planning to have my limit set for 75 ms - 100 ms

[solemn helm]

Im calculating the damage on the server, and then multicasting an impulse for the hit, if I was unclear

[frosty heron]

That sounds like the wrong way to do it

Like 99% sure

Don't multicast anything stateful

You apply the impulse on server, it will replicate to client if you are using CMC

[solemn helm]

oh

now that I didnt know

[frosty heron]

I can't get that to work for pawn controlled by AI controller though

Still trying to work it out.

[solemn helm]

I do use a CMC

This shows both my approaches. the thing is that I want to setup a delay before the stamina regen GE

What's happening is:

First time:

Sprint ends
2 second delay works
Stamina recharges

Subsequent times:

Sprint ends
Delay is skipped/ignored
Stamina immediately starts recharging

I don't know why this happens. any idea?

[languid hemlock]

Should I worry about not clearing an actor reference from the arrays after destroying it? My actor exists in many different actor arrays. When it is destroyed, do I have to remove from all of them one by one, or will the garbage collector take care of it by itself?

[trim matrix]

how could i recreate a camera system like this in my game? https://youtu.be/-linPnvpX3U?si=zLqA5OTZ2HvnfDVL

[manic vessel]

In an attempt to get away from child actors I created a scene component that I want to be able to add components to the owning actor on a button press. But its not working in the actor BP when I press the button. what Am i not understanding.

[lime tide]

i have absolutely no idea how id even start, like how would i even detect on which elemnt an neutron is rn

[manic vessel]

Anyone see the issue with my editor events not adding components

[surreal peak]

You don't have to remove it but you have to be aware of the entry becoming null

[surreal peak]

Not sure if those nodes work outside of the ConstructionScript. I would simply suggest turning your Hand Mesh into an Actor and spawning that one. That still avoids the ChildActorComponent but will work a lot nicer

After spawning you simply attach the Actor to the one you are in.

[manic vessel]

I just got it spawning in the Scene , but cant seem to destroy them

[surreal peak]

Hm the DestroyComponent call in BPs checks that only the owner can destroy their components.

[manic vessel]

How does spawning an actor over using a child component actor differ

[surreal peak]

Your ActorComponent isn't the owner of the SkeletalMeshComponent

[surreal peak]

ChildActorComponents are the buggy shit

That's kinda all

[manic vessel]

k thanks for the feedback

[surreal peak]

Like they both spawn an actor but ChildActorComponents are known to be buggy and thus should be avoided

There is nothing wrong with spawning an actor in general though

[manic vessel]

I have been using them without issue, this was just an experiment to find if I could switch it to a sc

[surreal peak]

If you want to destroy the SkeletalMeshComponent you might need to move the DestroyComponent call into the owner

[manic vessel]

ok

[surreal peak]

Or change the owner to be the ActorComponent. But not sure that works.

It's a strange limitation of the DestroyComponent function they specifically coded for blueprints

[manic vessel]

think Is My goal is to turn these on \off in the owners BP scene for setting up hand positions and such

problem with actor component is I cant have many

[surreal peak]

You could simply set the visibility or HiddenInGame property instead of fully destroying them

[surreal peak]

Why not

SceneComponents get expensive, sure, but ActorComponents are fine

[manic vessel]

they are more arkwars to position on the owner

[surreal peak]

Hm

[manic vessel]

I will give that another shot

[frozen wren]

something about math...how do you balance odd numbers
example 3 by 2 is 1.5
i want to save this value so that one variable will set 2 and the other 1 instead of getting 1.5...if u understand what i mean
in more details i have 3 bots i want them to team up divided by 2....so A team will be 2 bots and B team will be one bot

[dawn gazelle]

You kind of need to decide that yourself what happens. Your best bet in this case is probably to look over the current number of any players in a team, and join the one with the least amount of players, if the number of players on the teams are equal, then you can either join team 1 or do a random between the two.

[frozen wren]

is there a way to get an exact nom

i do 3/2 i get 1

its an int

found a way

[dawn gazelle]

An exact number for what? Right now based on your example, you're diving the number of bots by the number of teams - which as you're finding you can't really use to try and equally distribute them. You'd have to convert to a float and then use either floor or ceiling then convert back to an integer again which is just kind of messy and not what you actually need to do.

The way to approach it is that if you have a bot that you want to fill in a team, you just check how many players are on each team and choose the one with the lowest amount of players, otherwise, just choose one of the two teams at random.

[frozen wren]

convert to float

so 5/2 equal 2.5

team a is 2.5 - .5 + 1 which equals 3

team b is 2.5 - .5 which equals 2

makes sence?

[dawn gazelle]

Again messy way to figure it out rather than just relying on the counts of the players in the team itself.

[dry socket]

Self-update: found the C++ code that's responsible, though I haven't worked with the code side of Unreal before.

[dawn gazelle]

0 players in the game... First bot joins, sees that both teams are equal... Joins team A.
1 player in the game (the bot on Team A)... Determines that Team B has less players, Joins team B.
2 players in the game (the two bots, one on Team A, one on Team B)... Determines that the teams are equal... Joins Team A.
You now have 3 bots "evenly" distributed between two teams without worrying about how many bots need to be divided by the number of teams there are. This can also scale in case you ever want to have more than 2 teams... It might be hard to figure out how 8/3 can equate to which team the bot should join.

[dawn gazelle]

Yea.. The CMC is meant more for handling bipedal characters... A dolphin, especailly if you're wanting them to be able to do flips in the air or something, doesn't really match too well with it.

[sturdy cove]

Quick question for those well versed in widgets and performance... I want HUD indicators of some set of actors. I can use Project World to Screen and dynamically add image widgets to the canvas and destroy them on the next frame, or update their position somehow, but this sounds very heavy on performance. Is there a better way?

[dry socket]

Honestly I've gotten about 90% of what I want out of it; the biggest unsolvable problem is the capsule, but I'm not being too precious about clipping geometry.

If I can turn off this pitch restriction while falling I'll be like 98%.

[dawn gazelle]

Things that need to update every frame so it's in the right spot need to update every frame. I wouldn't destroy and recreate them every frame.

[sturdy cove]

That's my intuition as well. Guess I'll need to figure out logic for counting the existing widgets from last frame and adding/destroying as necessary

Do you think using render targets would be a good idea? I have almost no experience using them

[dawn gazelle]

My gut says no, though I could be thinking that specifically because of SceneRenderComponents that are usually used along with them which are definitely taxing.

[dawn gazelle]

In order to do so with the CMC, you'd have to use C++ to create your own child component of the CMC so you can override that function and then create a seperate C++ character class that implements it, then reparent any blueprints you have to then use your new custom C++ character class.

[ruby cobalt]

hmm an BP with compile error will absolute not run at all, correct?

I got errors atm related to a missing class but that shouldn't affect what i'm doing and I want to bring back the missing class later..I don't want to delete the errors... what can i do??

[dusky cobalt]

unplug execution

[dry socket]

In Editor Preferences you can keybind disable/enable blueprint nodes (I believe they're unbound by default), and disable nodes you don't want to run in the short term.

[ruby cobalt]

i don't use keybind very much but i believe they won't work in any BP.. I think what works best is having this stuff in your pawn or in the game mode?

i use midi and osc the most so i don't really ahve to tackle this stuff

[dry socket]

it works in blueprints. I'm not a big keyboard shortcuts person either but adding to the right-click context menu is more complicated. But if your blueprint is throwing an error and you want to avoid that without deleting the nodes, you either need to disconnect them as Amberleaf suggested, or disable them.

[carmine scaffold]

hey im using common ui and enhanced inputs to handle my input remapping, i want to know if its possible to use icons using an image to show the input instead of using a text block?

[ruby cobalt]

ahh thanks

[ruby cobalt]

ohh thanks.. I realize now that I was discussing something else from another UE server here.. sorry for the confusion

[dry socket]

ah, I see - not like that. You need to go to Edit > Editor Settings and search for the keybind, like in my screenshot. (searching for "able node" will find both Disable Node and Enable Node)

[ruby cobalt]

yeah sorry about that!! haha

both discussion refered to key binding so i got confused

so disabling the node and unpluging execution are two really good solutions! thanks

[dawn gazelle]

Instead of destroying the actor, use the "Apply Damage" node and be sure to give it a damage value (it can't be 0 or it won't trigger). On the actor that would be receiving the damage implement the "Any Damage" event and then manage whatever you want to with the damage value you've passed through.

[obtuse violet]

Hiya! I'm trying to do some UI blueprint stuff to make an options screen that'll let you access a PNG that shows the controls and credits,

The controls work fine! But for some reason the game won't let me see the credits? Even though their setup is the exact same as the controls!

Could I get some advice please?

Wait a damn minute

That's embarrassing

[tiny tundra]

Hi! I want to do what is shown here, BUT keep collision/etc. Only want to control the visibility (so that nothing is being drawn) but I don't want that geo/etc to no longer be interactive.. make sense?

[frosty heron]

@tiny tundra iirc toggling visibility doesn't modify the collision. If that doesn't work, tick hidden in game instead.

[tiny tundra]

it does modify when you are selecting the level. I guess I gotta select all the actors from the level and perform an action on them

[unkempt valley]

hi! i need help making it so when my character's health reaches zero, it spawns a new character and becomes that one. I have a health system and the new character made. 😄

[tiny tundra]

this ended up working -

[sharp sable]

hi everyone, can someone tell me how cooked i am with this code ?

its supposed to : make sure i loose stamina while sprinting, verifie if im sprinting to not add stamina, make sure i cant sprint if i dont have stamina anymore...annnnnd idk , forgot

just made the code, idk if it works x) it look fun cause there is so much line xdd

[frosty heron]

Using delay to do something over time is horrendous in the first place. A timer would be a better alternative.

[sharp sable]

'timer' ? wdym

and actually it work, and i learn something interesting : if it works, dont touch it.

so i will not touch it again. never.

here is the 'final' code for this. it works, pls dont tell me to change anything

[pulsar osprey]

why post it if you dont want to listen to what people have to say?

[sharp sable]

bcs i posted it just to show it cause it looks hilarious how dumb i made my thing

can't i ?

[tough badge]

The "Set Timer By..." nodes can do something every X amount of time you specify. So if you have an event "Subtract stamina" and set the timer to 2s, it will Subtract stam from your character every 2s until you tell the timer to stop

[sharp sable]

yeah i know but to be honest, im scared of this cause if it does not work im more then cooked

[tough badge]

You can just disconnect the pins on this implementation, move it to the side, and try out the timer thing

[sharp sable]

but lat's take a look , ill try

[tough badge]

if it doesn't work how you like delete it and reconnect the old way of doing things

[sharp sable]

yeah why not, you right

so you said, timer by event right ? but idk what exactly to do..

[tough badge]

lemme show a example give me a sec

[sharp sable]

okay thks

[tough badge]

I didn't copy all your variables but this is basically how they work

[sharp sable]

okay this looks pretty nice but what is the clear and unvalidate timer.. ?

[tough badge]

just stops the timer from firing

when you do the "Set timer by..." n odes they fire until you clear them

if you set them to looping

[sharp sable]

okay okay but with this node how does the game knows when to clear and invalidate ?

[tough badge]

Depends on how you have the sprint set up

if it's held down then when they release you tell it to clear the first timer

[sharp sable]

oh okay, im watching your screen, taking the time to understand all that

[tough badge]

when stam reaches max stam then clear the add stam timer

So I guess for you using the regular input system on released is when you invalidate the subtract stam timer

[sharp sable]

okay i see

thks sir

[tough badge]

np

[sharp sable]

the only thing is i use the input i made on 'projet settings' you know, could it work the same ?

[tough badge]

Ye it should

[sharp sable]

okay.. thks

[frosty heron]

You shouldn't use legacy input.. they are inferior in every possible way.

Anyone serious about their project should use enhanced input.

[sharp sable]

As you say “anyone serious about their project” but I’m a beginner in blueprint, even in just “programming” that why I do… dumb things, just cause I’m learning, also… idk what you talking about “legacy input”

[frosty heron]

Legacy input is what you are using. Beginner or not is irrelevant. It's just what anyone would advice when they see an ancient deprecates system being used.

You can follow epic doc to set up enhanced input. It's not hard to set up.

Even comes with example when you create a template project.

[nova grotto]

im trying to do a sphere trace on begin play and for some reason its not getting a hit but if i do it manually it works no problem is there something im missing abouit begin play

[frosty heron]

Show code

[nova grotto]

ok this is the game mode begin play

[frosty heron]

Are you doing multiplayer?

[nova grotto]

and this is the lockon code

[nova grotto]

will be but not there yet

[frosty heron]

Wdym by manually btw? Perhaps the hit actor wasn't spawned yet at the time of the trace. It's hard to tell.

Try adding artificial delay just for sanity sake and see if it's hit anything.

[nova grotto]

oh my b i set up a debug key

[frosty heron]

By "doesn't work" do you mean you actually don't get any hit trace or your lock on simply doesn't work?

Because game mode only exists on server.

So you are trying to do lock on on the server copies. This is probably a mistake.

[nova grotto]

i dont get a trace hit

[frosty heron]

Locking should be done locally imo. Not server initiated

Well no more idea at this point. It's too hard to debug without having the project at hand.

I can only advise to debug and perhaps try to do it outside game mode and do a test on single player. Purely with just actor and another actor and trace on begin play of the test actor.

[nova grotto]

ya im super confused on why this is acting the way it is

[nova grotto]

just tested that and got the same result

[frosty heron]

I will check after work

[nova grotto]

thank you

[tawdry osprey]

Someone possible help me with enabling and disabling the physical constrains node. I’m trying to achieve a wobble effect on weapons that are holstered. I have functions I can call inside my weapon blueprint, where the physical constraint blueprint is located, for equipping and un-equipping. I figured it would be as simple as activate and deactivate but it’s not seeming like that. I’ve tried setting the values to 0 and locked off the event for equipping and un-equipping. And still won’t work out how’d I like it. I’d like to have where when I have the weapon equipped the constraint isn’t active and opposite when it is holstered.

TLDR: how can I enable and disable my physical constraint inside my weapons blueprint.

Thank you

[autumn parrot]

hey anyone ever ran into this issue, my meshes are like scattered in the viewport, how do i put them together, its a building that i am adding to my game?

need like a shortcut or something

[true valve]

I added a cull distance volume. And I placed a static mesh barn actor in my map. I tried various setting but not effectin my actor. Any idea>

[uncut shale]

why does vinterpr just teleport? I have messed with both values for the past 2 hours, but nothing works

I want to move an enemy towards a stationary object, but no tutorial has helped me out thus far

[maiden wadi]

You didn't give it a correct delta time.

[uncut shale]

what would be the correct delta time?

i have conneccted it before with event tick, but it still teleports

[maiden wadi]

DeltaSeconds from the Tick node. To interpolate correctly, the math needs to know the time from last frame to this frame, which will be your delta seconds.

[uncut shale]

still just teleports

[maiden wadi]

Lower the interp speed.

[uncut shale]

huh that wasnt working before. Btw is there a way to only change the X and Y? the enemy keeps sinking below the ground

if not, ive literally just been messing with the Z value, its ok if that was the solution

[maiden wadi]

Hmm. You can do some stuff with breaking and remaking the vector with the original Z. Like after the Interp, breakVector and then MakeVector. Use the X/Y from the Interp's Break. Then break the GetActorLocation and it's Z value.

[uncut shale]

my next question would be how would I get my turret to face an enemy?

right now its just an arrow, and every time i want the enemy to come into range, i want the turret to look at that enemy and fire a bullet

[scarlet root]

Good morning.

Is there really no one who can help me here?: #blueprint message

[frosty heron]

break down your problem into smaller task first.

• Rotate turret to look at enemy
• Use interpolation to rotate so rotation doesn't snap
• Fire the bullet when the turret face the enemy
• Add offset to shoot ahead accounting for distance and velocity. Add some randomness so the it is not always 100%

starting from your first task, you can look up online ways on how to rotate an actor to another actor.

another countless tutorials but I would advise to just understand vector math.

[uncut shale]

honestly the bullet firing would be on a cooldown. I think if I get some sleep, I can come back tomorrow refreshed, as trying to get the enemy to move to the tower was the difficult part lol

[frosty heron]

Hold your horses on firing when your turret hasn't face the target yet

[uncut shale]

yeah

i know how to fire it, its the rotation that will kill me

[frosty heron]

the rotation isn't that difficult

there is even a helper function already

FindLookAt node

[uncut shale]

would that work with a component?

[carmine prawn]

I can't claim to know the answer, I have saw a few people over the years encounter this. I'd hazard a guess and say you'll have to add some kind of sanity check on your spline and check the rotation of each spline point using something like Get or Set Rotation at Spline Point. Like I said it's only a guess though. However, it may not be related to that, it could be something else.

[uncut shale]

@frosty heron gonna test tomorrow, but this is the blueprints I have. Every time the enemy enters the enemy array, and the turret is constantly "looking" at the enemies. After I make sure this works, I will have firing happen on a cooldown

[dark drum]

You're top spline point probably needs rolling 180 to maintain the correct rotations along the spline.

[scarlet root]

thought so, too
But no..
I think this happens because of the Up vector of Splines, not correctly dealing with Gimbal lock :/

[dark drum]

Rotate it in the opposite direction?

[tight pollen]

can someone help me?

what exactly is up with AssetThgumbnailPool? I've never had this happen before while playing

[scarlet root]

Nope - result remains.. it always twists at the point where the verctial-roll meets the up vector..
And it seems like this value cannot be changed that easily..

hmm...
Maybe i will go for predefined pieces, done in Blender.. Possibly easier to handle that in curves..

[kind willow]

I want to have a weapon that deals more damage the longer you hold the trigger, the issue is that you can let go of it just as the firing animation starts and the start holding it immediately again, allowing the player to charge the weapon while the gun is in the firing animation. Is there a way to reset this value or should I make a custom variable instead and zero that?

[dark drum]

FAssetThgumbnailPool is a class for managing thumbnails for assets. Whats the issue?

[dreamy mountain]

anyone know how to fix this when possessing a pawn?

[dark drum]

How do you set the camera position?

[dreamy mountain]

i dont set it?

just a camera already there

[dusky cobalt]

i mean you are possesing camera that is somewhere in the level and your viewport just goes there.. not the other way

[dreamy mountain]

so how would i fix it? i cant figure out why being close to it and possessing it doesnt set it to the camera

[dark drum]

Is the camera set to use the control rotation or anything like that?

[woeful pilot]

does anyone know if you can create level instances from a blueprint? Get all Level Actors Convert to Level Instance kind of thing

[dreamy mountain]

i dont think so?

[narrow sentinel]

anyone know if theres a way to get from the string a specific string

well part of it to pass through to the switch

I bassically want to strip out the found bit

leaving say if it says AudioSlider_Main it would leave Main to continue on

[dry sleet]

Not much help here with regards to Blueprint, but the function invoked by the context menu seems to be:

ENGINE_API ILevelInstanceInterface* CreateLevelInstanceFrom(const TArray<AActor*>& ActorsToMove, const FNewLevelInstanceParams& CreationParams);

sadly it doesn't seem to be exposed to Blueprint at all

It would probably be fairly straightforward to make a simple wrapper to call this function from Blueprint, but you'll need to ask in #cpp .

[narrow sentinel]

nevermind sorted it

[ruby cobalt]

I get this crash error when trying to open one of my BP:

Assertion failed: BoundProperty [File:D:\build++UE5\Sync\Engine\Source\Editor\GraphEditor\Private\KismetNodes\SGraphNodeMakeStruct.cpp] [Line: 398]

problem is.. D: drive is actually a midi controller lmaooooo

i tried getting rid of the D drive completely.. no luck.. what is this

[granite frost]

my line trace is working weirdly. For this specific item. Its hitting an object at mid here and showing that it has hit the item it was supposed to reach but the fun fact is that actor is set in actors to ignore. So it should not be hitting it. I want using it to detect if the interactable item is not behind another item.

its working with other actor

line trace channel is visibility

[vapid ledge]

How do I check if a parameter exists and use it in an if else statement in a material layer?

Is this even possible?

I'm trying to make a master material for my landscape but there are several different formats textures come in with depths rgb orm ordp etc..

Is this REALLY the meta for materials??...

No way to do this in C++ or something? this feeels so bad

[vapid ledge]

See how these are enabled with checkboxes? How do I get that variable "is enabled" from within the material graph?

[thin panther]

You don't, it just falls back to its default in the parent iirc.

Also material graph is not #blueprint

[vapid ledge]

What is it ?

[thin panther]

#materials

Blueprints are another language entirely

[dim agate]

Tilt your object and then add relative rotation.

[narrow sentinel]

Anyone know whats wrong here ?

I have set the Prompt text table thing to something valid but when I compile and save it moans that I need to connect something ot the get data table row which I have

my data table also has valid entries so

wait nevermind

I think I sorted it, on the get data table row I need to select the asset rather then using the variable

[high iris]

Say you're not planning to reuse your actor components on your ACharacter busclass, but you mostly use them to split up the main player class into smaller chunk that you can check out and work on separately. Do most people eventually get to the point where they have so many ACs on their player that it actually becomes hard to reason about what component does what?

[surreal peak]

Possibly? Dividing it too much isn't helpful either.

[dusky cobalt]

Give some examples because if you can divide some logic into components and reuse it, i don't see a problem. Myself I don't think even 15 components is bad. Imagine you put that 15 components logic into one file and imagine digging that 😄

[desert juniper]

It may be coming from the extreme composition that some unity devs who watched the SO GDC talk like to push
a health component, a sprint component, a stamina component, etc

[dusky cobalt]

Once you start using components there is no coming back 😄 everything is a component xD

[languid hemlock]

GPT said that unless I remove the actor from the arrays, the garbage collector will not handle it and will cause a memory leak. I'm not sure if that's true or not. I am now removing it from the arrays to be sure though.

[frosty heron]

That's bullshit

But you don't want null unless intended ( maybe like a slot bars where the slot can be null )

[dusky cobalt]

There might be situation like when you have actor in array, it's destroyed and you might try to access it and it may fail. It can actually happen.

but just checking if it's valid should be ok

[surreal peak]

(: ChatGPT sucks.

If an Actor gets destroyed, it will get cleared out of the Array.

Or rather the pointer will be nulld.

It's pretty normal actually that you might have an Array somewhere that you don't actively manage, that could potentially have a nullptr in it then.

An AI could have a List of Actors that it has AggroValues for. If an Actor dies it would have a nullptr entry.
So in those cases you just check if the entry is valid before accessing it.

If you really want to you can always bind to Destroyed methods of actors you keep track of and clear their entries when that calls.

[narrow sentinel]

Anyone know what could be going on here ? I'm trying to open a level but have it where it blocks any further exection until it's loaded the level to then set the player location etc

at the moment it doesn't seem to be loading me into the level

i've checked and I'm giving it the correct level name

[bronze mirage]

hey dudes, anybody here using world partition w/ BP actors? how do you prevent world partition streaming from constantly firing off the construction scripts on actors in the editor? on my project pretty much every time somebody works on a world partition level they're getting revision control "unsaved assets" for actors that have re-generated and are now "changed" as far as perforce is concerned

[snow halo]

how do you do this ?

without casting

[dim agate]

Didn't work in what sense? Post your BP if you can.

[faint pasture]

you need to at least cast to Actor

you don't KNOW it's an actor yet

just that it's an Object

[snow halo]

but if I cast then whats the point of soft referencing?

I guess its something different if you use purple cast

[faint pasture]

I'm pretty sure you have Actor loaded lol

[snow halo]

and cast generically to actor

wait

[snow halo]

I dont have actor loaded yet

[faint pasture]

yes you do

[snow halo]

but this is async

[faint pasture]

you're saying there's zero actors in your entire game at this time?

[snow halo]

and its soft ref

[faint pasture]

Actor as in the class Actor which is the base class for damn near everything

you need to be sure it's at least an Actor, you don't need to know the specifics beyond that, because you can't spawn a Texture or a Connection or an Animation into the world, you can only spawn Actors

[snow halo]

oh i see

This is what a friend of mine told me earlier

Dude if u cast your foing thr opposite of a async load lol
...
...
Anytime you cast your making a hard ref to that. If you spawn actor, that is also naming a hard ref. Spawning from a soft class avoids the hard ref if you do it right but loads during the async load
...

[faint pasture]

A hard ref to Actor is fine, you're trying to avoid a hard ref to Actor -> ??? -> ??? -> YourSpecificActorClass

[snow halo]

true, I guess casting is fine If I just cast to actor then

[dim agate]

Which part doesn't work? The angle or is it not spinning/rotating?

[trim matrix]

i have this signpost bp made, and an interact interface added to it that displays a widget with an array of text assigned to it, but im having some issues im not too sure how to fix, when the player does interact with it, the text dosnt display properly, instead inserts a blank page after the final array, and then i cant reactivate the signpost after ive interacted once

[surreal peak]

Index must be less than length, not <=

And you probably want to reset the index back to -1 at the end

Also based on your video your index seems to start at 0 and you instantly increment it

That means you are skipping index 0

Array indices are from 0 to Length-1

So you want to set its default value to -1 too

[errant violet]

Unsure if this needs a really long complex answer but I am unsure how to effectively google this so I have come up with 0 helpfull results thusfar. I am mainly looking for a global/fundamental answer rather than super specific

For a gamejam my project will contain the same house except for different events happening, different item locations, and some stuff like that (Think 2016 Tattletail or P.T.). Initial idea was to create a level with the house, and then duplicate that level and make changes there to what I need it to be. Problem with this is that if I make changes to 1 level (let's say I change an entire room after testing) I would have to repeat this same change over multiple levels rather than just changing it in one place. How could I create this to where I only have to change 1 thing, but it updates everywhere?

[trim matrix]

so after i set the text set the index to -1 again

[surreal peak]

Set it to -1 when you close the widget

And its default value too

And change the <= to <

[trim matrix]

now the widget isnt displaying at all 😭

[surreal peak]

LevelStreaming

[surreal peak]

You mixed up the < condition

[trim matrix]

i see that now 😭

[surreal peak]

TalkIndex < Length

[surreal peak]

Your House can be in the persistent level, rest of the things that should change can be in various streaming levels that you can load and unload

[trim matrix]

the pages are now working, but i still cant reactivate the sign after i have read it once

[errant violet]

aaaah I see I see, interesting. I'll look into that then thanks! A direction is all I needed haha

[surreal peak]

It's because you aren't setting the widget to null after removing it from parent

The pointer is still valid so it calls set text on it instead of creating a new one. And since the IsValid checks skips the Add to viewport it will also not re-add.

So simply set the widget variable to null/none after removing it from parent should help

[trim matrix]

how do i set it to null?

[surreal peak]

Just set it without connecting anything to it

[trim matrix]

so just another set ui variable?

[surreal peak]

Yes

After the Set TalkIndex -1 or before it. But generally after the Remove From Parent call.

[sturdy cove]

Is there any reason a widget would invalidate a reference coming into it? I'm sending a BP_PlayerState to a widget and TeamID defaults to 0, and player name is empty. The player state is valid coming from the player pawn, where the event is called

For context, this is so players see the IDs of players on their team

[trim matrix]

oki ty that is now working, where in my setup would i add some logic to lock the players input to only the sign until they finish reading it that way they cant walk away with the sign ui

[surreal peak]

Depends on how you time this. PlayerState being spawned doesn't mean it instantly also replicates to the client. If you directly call an RPC it might still be invalid locally. And if it's valid then the second thing that can be is that you are setting the team id and then instantly RPC

In theory you'd need to wait for this stuff to replicate before doing anything with it

Which would be for with a RepNotify variable

[next kite]

hey guys, is it possible to use a cine camera during gameplay? (its for a pause screen)

[mystic blade]

so what im trying to do is increase the forward and vertical launch distance while the key is being held. default for forward is 100 and default for vertical is 300. i think its working the way im wanting it to but not entirely sure

instead of adding i changed it to multiply and it seems to be exactly what i wanted it to do

if anyone has a better solution, ill take what i can get

[trim matrix]

any idea why when i duplicated the blueprint for my sign the duplicate dosnt display the ui but all i changed was the mesh in the duplicated blueprint

Having issues with getting into and out of a vehicle.
https://blueprintue.com/blueprint/qhnz4du1/
Above is the code in the Character Controller/Blueprint (edited)

https://blueprintue.com/blueprint/jevpoomd/
Above is the code in the Civet Pawn blueprint. Below is what is happening. The character will not abandon its collision with the vehicle and so instead of being placed on the vehicle on the "Seat" socket, the character is placed above it. Finally, exiting the vehicle leads to the camera no longer centering around the character.

[trim matrix]

the original sign has the same nodes, and it works

[mystic blade]

how can u even tell what the hell is going on with that blueprint?

[trim matrix]

bc i just made it.. 💀 i havent had time to clean it up yet, my focus is getting it working lmfao

[mystic blade]

oh

[vapid sedge]

Hello, why is my Widget Object reference not visible in my data table?

[dusky cobalt]

I think if it's valid you are not adding it to viewport so when you try to remove there is nothing to remove?

[trim matrix]

but its working just fine in the other blueprint

[dusky cobalt]

how does your sign knows which widget belongs to it?

how do you call event talk?

[trim matrix]

bc theres only one sign widget

[trim matrix]

in my player bp

[dusky cobalt]

add break points and debug it, add print strings

[trim matrix]

the only thing its erroring is the remove from parent node, but the other blueprint has no errors

[vapid sedge]

?

[dusky cobalt]

try to change it to User Widget

[vapid sedge]

already did

think i found a bug 😭

[prime fulcrum]

I am trying to get an object to float up and down but it is moving to the end position instantly

[unkempt valley]

sooo im def dumb but this works perfectly for the host however not the other players, how can i fix this 😄

when you shoot the item that has the tag you take 5 damage. works for host, not anyone else

sorry here is full thing

[frosty heron]

Any idea how navmesh stops working in package?

For the creation type, i need it to be static.

[sturdy cove]

How can the array of structs be empty if I just added to it? (the custom struct is an array of BP_PlayerStates, and the code is being run on server in BP_GameState). The same behavior occurs whether Teams is replicated or not.

[frosty heron]

Why is client telling a server if "a player joins"?

Oh by join you mean in the context of team.

Nothing is plugged on the add node btw

[sturdy cove]

Oh what the absolute

[sturdy cove]

I can't believe I missed something so simple, for hours. Thanks

Oh no I unplugged that intentionally earlier. still doesn't work

[frosty heron]

You probably need to cache the index out of the random node.

It might be running per execution

So what you add and when you access may be different jndex

[sturdy cove]

"array is empty"

And playerJoins is being called from GameMode onPostLogin

Seems like this should work right?

[frosty heron]

Don't know but it's weird that you are calling server rpc

I don't know how player join is called

Game mode is server only already

If you want to handle it on server side then don't need any rpc.

You use server rpc when the client needs to tell the server something.

[sturdy cove]

Yeah, GameMode is calling that to the GameState. and the same behavior occurs with no replication

[frosty heron]

Print string the player state and the content of the struct after adding.

[sturdy cove]

I did a "get player name" which returned OK

[whole anchor]

hi all, i've been messing around trying to make a physics based floating capsule character in blueprints, but im having some trouble creating a good feeling spring-iness to the floating capsule at the moment. I'm basically trying to do the math described at the timestamp in this video here: https://youtu.be/qdskE8PJy6Q?si=Cbjdub5SrPTn6ckr&t=115, and I thought that the vector Spring Interp node would be what I'm looking for, but I'm honestly just not sure how this thing works. Does anyone have any info on this node?

[sturdy cove]

I'm iterating through everything in the array, and it doesn't see the added data at all. It's OK coming in, so the "Add" node must be where it's failing.

[tough badge]

Maybe the random node is getting called twice? Giving you a different team by the time you get to the branch node? Try doing a sequence where the random team and cache happen then on the second pin do the rest and see if that changes anything

[sturdy cove]

This function prints everything in the datatype. If that were the case, it would tell me

[sturdy cove]

And it's cached here

[tough badge]

The cache doesn't matter if the random node is called twice before it gets to the branch

[sturdy cove]

Maybe. But after inserting, there’s nothing in the array, random or not

[tough badge]

Yea that makes me think the array it's checking is empty, but your function prints an array that's full of info

makes me think you have two different arrays here, not the same one in a super position of empty and full

Print the index of the array when it's cached and print the index when it gets to the branch to make sure it's the same array

[sturdy cove]

Right after Add, I’m doing PrintAll with Teams

Maybe it’s adding to a copied array?

[digital glacier]

is this the best way to do this

[frosty heron]

No, stop using flip flop node outside prototype.

Even with prototype you can just use a bool

[digital glacier]

wdym?

[frosty heron]

I mean what I write, don't use flip flop node

Just use boolean

[digital glacier]

is that not what it does behind the scenes

what difference does it make

[frosty heron]

Sure but you can't access the internal bool

The difference is the state is locked

Let's say you crouch with flip flop

How can you save the state of crouching?

If you still gonna use it at least know its limitation

If you don't know how to flip boolean, just set it to its own value but flip it with not boolean node.

[uncut shale]

for some reason, whenever an enemy enters the collission sphere, it adds 2 to the array, any reason why this would be the case?

[frosty heron]

Add unique won't add the same reference anyway.

You should check the content of your array

[uncut shale]

i have 0 clue why its adding each enemy twice

@frosty heron would it add twice because its a sphere?

because i have 0 clue why it is adding it twice, when its only one enemy

[frosty heron]

Maybe you overlap something that has matching tag. Enemy or not.

[uncut shale]

the only thing with the enemy tag is the enemy

its printing the same enemy twice

[sturdy cove]

I think I need to get Teams[x], add Player to that array, and assign Teams[x] with the result. So the player is explicitly added. Sanity check anyone?

[uncut shale]

ah yep thats what it was, the object inside the actor was generating overlap

[frosty heron]

It's most likely you have 2 actors that check for the overlap

Append the string with a reference to self.

[uncut shale]

nope, the object inside was causing overlap

[frosty heron]

Just print string self along the reference

[uncut shale]

anyway, im struggling with the logic of my firing event

I want every 10 seconds for the turret to fire, but idk how

loops only do it for a set # of things, but i want the turret to constantly be firing

[frosty heron]

You will have issues too if you don't know how many actors you expecting to check.

[uncut shale]

I already fixed the issue

[frosty heron]

I will strongly advice you to print a reference to self on top of the print string

[uncut shale]

the issue is fixed bro

[frosty heron]

Add unique does not add the same element

[uncut shale]

DUDE

THE ISSUE

IS

FIXED

the issue was that the object inside of the enemy was creating collision events

[frosty heron]

And I'm showing you a way you can easily check this

But what ever

I don't want to argue

[uncut shale]

I was already checking it

i want this to constantly be looping, but every single time i try, unreal freaks out and says it creates an infinite loop

how can i go about making this repeat constantly

[frosty heron]

By knowing how to use timer

Look on any video online

You got nothing hooked to the event

Also you are calling it self every frame

Hence infinite loop

A function that call it self is generally no no for this exact reason

[uncut shale]

oh ok

@frosty heron what does delegate do exactly?

[frosty heron]

Connect the red event delegate to a function.

When the timer reached 0, it will fire the event you connect.

[uncut shale]

so the event Fire will happen every 10 seconds then with this logic?

[teal tendon]

So guys could you help me out with this one? I wanted to implement a mechanic where a player would have a telescope that could look into the sky, stars and constellations. If he looks below the horizon he would see the zoomed land perspective from where he is looking and while looking up in the sky he would see stars and constellations. The thing is I was thinking of implementing it not on the sky dome but rather locally inside the telescope to save performance and effort. So first of all I want to ask which option which would be better projecting inside sky dome or the telescope for the current scenario and second how could I implement them logically in Unreal 5. And if there is better method than both of them , please help me out here

[wicked violet]

Does anyone have any resources for creating a turn circle/fixed turn radius for an animal character in UE5? Preferably in such a way where the movement is oriented to the where the camera is pointing if that makes sense

[wicked violet]

Nevermind, finally found a great tutorial for this https://youtu.be/KZvGTbYQlyI?si=_uqW8FSfFxh9Ss30

[dark drum]

I feel like a post process material might be the best option. Possibly using the stencil depth to control where it should overlay the constellations.

[leaden peak]

im getting a there can be no null modifer but i havent gotten any null modifiers here so im confused

[frosty heron]

show the error log

[frosty heron]

are you sure this is the whole Mappings?

[leaden peak]

yup

[frosty heron]

So you don't have anymore binding? Just IA_Move?

[leaden peak]

yep thats it

[frosty heron]

can you collapse it and take a picture of the whole assets

the only way I can reproduce your error is if I add a mapping with null Input action

[dusky cobalt]

either this error is already outdated (happened when you deleted it) or just try to restart editor and see if it still is there

[frosty heron]

collapse this and show more

[leaden peak]

so its saved when i pressed save all

like in editor hang on im restarting editor

its fine after editor restart bit of a strange error hope they fix this soon

[dusky cobalt]

it showed probably for a second when you didn't have modifier yet, after you click save all it doesn't refresh the errors or make them go away, they will persit in the error log until you clear it, even if they are not existing anymore

[granite frost]

Hello guys. I am facing a problem with combing blueprints I learned about child actor component and I can use it to add blueprint as child of another blueprint but Now I am facing a problem with it. First I can't seem to edit the components of the child actor. Its becoming hard to do so since I was gonna edit those components for each different blueprint so then I thought of using vairables and making them instance editable but I can't even see those properties in the editor, even for stuff like actor references that I am supposed to refer in variables of those child actors. I can't see the variable and thus can't fill them too, they're visible in the blueprint viewport and not on the editor but I need to fill them on the editor

Is there a way to tackle these or the only way ia to make a setup function of sort and get all those values by making another variables in the main blueprint and then pass them on?

[frosty heron]

I would advice to not use child actor component at all. They are broken in nature and never been fixed for a decade.

Even Epic employee says to not use child actor component. It was used as far as to spawn special effects in fort night but it will never have place for important gameplay.

[dreamy mountain]

anyone know how to make this replicate?

like what settings do i need enabled for the material, and the blueprints to replicate

the joystick and buttons are all their own bp

seperate from the machine, but are child actors on it, and the screen is just a material over a plane

[dusky cobalt]

Don't use child actor component. Also if you want to even access the variables from the class of childactor you would have to Get Child Actor Class and then cast to the class you need (after you assign it in the details panel). You can also Set Child Actor Class, and then access that class. Generaly from what you are writing it doesn't make sense and 100% you can make what you need with components or with something else.

I am trying to merge 2 different blueprints. To make it act as one. So its easily to move them around and treat as a single entity.

Is there no option to merge 2 blueprint's?

Is inner heirarchy really not possible?

[dusky cobalt]

If you are forcing some things it means you are probably using wrong tools for the job that needs to be done

Find the right tools for what you are trying to achieve

[granite frost]

I don't understand. What do you mean by tools?

[dusky cobalt]

Why do you need to merge 2 blueprints?

[granite frost]

Redundancy.

[dusky cobalt]

Find other way / workaround for what you are trying to achieve

You are trying to fight redundancy with trying to merge 2 blueprints?

Sounds like job for Actor + Components with functionality that needs to be ''merged''

[granite frost]

Basically. I created an actor. And I have a special case where I need to use more than one. To be specific. I am creating a table and its drawers.

It has 5 drawers all of them interactable to be opened. I created a class for items that can opend and make all 5 drawers as that blueprint and now I want them as part of table. As single unit

I don't want to define same like for kitchen drawers, table, cabinet, almirah as so on which has varying number of door and orientation to open.

So I created an opening blueprint and want them as doors and be part of the whole furniture blueprint.

[dusky cobalt]

Sounds like you want 1 Static Mesh for a frame of the table with 1-5 static meshes for the Drawers. When you click each Static Mesh, it opens (Add Offset with Interpolation). If you need additional things to happen you need to somehow make each drawer have ID or just use Drawer as Key for TMap and then for example access TMap [Drawer][Struct with Data (items)]. Probably other ways to do it as well but would need to know what you really need, because if it's just for click - open and show widget with items inside then something like above would work with a bit of adjustment to what you already have (where you store info about items in that drawer etc).

If you want to literally just put things into the drawers, just need proper collision so these things will move together with you opening the drawer.

[dreamy mountain]

any ideas on this? ive set everything to replicate but it doesnt replicate any movement or material stuff

most look like this

[dusky cobalt]

https://cedric-neukirchen.net/docs/category/multiplayer-network-compendium/

Good luck 😄 and also #multiplayer for these questions is right place

[dreamy mountain]

didnt know that existed

discord hides channels

[granite frost]

In any case, I have made it work. Just what exactly is broken about child actor? Please let me know so I can weight up my advantages and disadvantages?

[dusky cobalt]

I recommend doing your own research, its easy to find info about it in unreal forums and examples how people wanted to use it and were told to use something else.

[livid flare]

Hey @dark drum about the run input code you posted, can you please check if you had something on tick?

I'm still trying to figure it out why isn't working 🙂

[maiden wadi]

In short, map serialization. You won't get a clear answer on this because not a lot of people use them, and even fewer people deal with file saving. But they have problems with being saved into maps. EG you put a child actor component on an actor, place tha actor in the map, and then save the map. Known bugs are that occasionally the actor doesn't spawn anymore. Other times it spawns multiple of the same actor in the same place.

I use ChildActorComponents at the moment, but I'm only using them as a temporary measure until I finish writing my actor customizer. And I only ever spawn them at runtime, they are 100% never, ever, for any reason serialized into maps or savegames.

[dark drum]

No, nothing on tick.

[silk cosmos]

This is where you would fine use in something like an actor component as an alternative to an actor. I would create an actor component called OpenAndClose and move this logic to exist in there. You can assign tags to your drawer meshes and fetch a reference to those meshes and cache it on begin play inside of the actor component. Add a component for each drawer and you don't need the head ache of child actors

[granite frost]

I see so in short the answer is to create a component. I see thats a good solution. I am idiot for not realising it sooner. Thank you guys, actor component would fit my need perfectly!

[ruby cobalt]

I need a system that can receive either a static mesh or a skeletal mesh. I'll use something at construction or at beingplay to cast it and handle it properly. I'm thinking of doing this instead of making two very similar child classes.. the same class can handle both.

What kind of component i can use as a variable to set the asset i want

[dark drum]

I believe both static mesh and skeletal mesh components are a child of 'MeshComponent'. Not sure if you're referring to the asset itself though. If you're on about the asset itself, i believe that's 'UStreamableRenderAsset' but not sure if that available in BP.

[solemn shale]

Guys, after my respawn event my Healthbar and ammo UI not updating correctly what might be the reason for that. I created my UI in character BP beginplay and im handling the deathevent in Event Anydamage

[trim matrix]

hi i have made a ui health widget that appears when the player takes a hit or gains a health point, but i want it to then go back to being hidden again until the player gets hit or ups their health again, but im not sure how to make it go back to being hidden after a few seconds since i cant use a delay in my function (first bp is in my player, second is in the widget)

this is what it does rn

ignore the audio fully forgot obs is capturing it too lmao

[surreal peak]

Just use SetTimerByEvent.

That works inside functions just fine

[trim matrix]

how do i use that? just like where i would put the delay normally?

[surreal peak]

Yes

But you connect an event to it that gets called instead of the exec pin being the delayd call

Make a function or an event that has no parameters and no return value, e.g. "OnHideHealthBar" and then drag the red square pin of the set timer node out and search for "Create event". That should give you a little node with a drop down that lets you select the function/event you wish to call when the time finishes.

The returned TimerHandle can be used to cancel the timer in case it's running and you get healed/damaged again

So it's usually useful to save that to a variable so you can reuse it

Fwiw setting the timer again will simply reset it. So the timerhandle isn't always necessary

[trim matrix]

should i do this in my player or in the ui itself

[surreal peak]

UI

[trim matrix]

so like this?

[surreal peak]

Yeah, now you need to set the time to something other than 0.0 and you need to click on SelectFunction to select a function that you made that then hides the UI

[trim matrix]

oki i got that working now trying to make it if the players health is only 1 the ui for the meter will not dissapear and will flash instead until they heal, i made a bool for it and have it being set to true when the players health is equal to 1, and then set to false when they heal or respawn/die. but im not sure what to do for the rest of it

ok whatever i was trying broke it 💀

[trim matrix]

i have it slightly working now, but if the player stays in the damage hitbox, the ui goes hidden

[dusky cobalt]

If Health > 1 -> Hide Health

[trim matrix]

?

[dusky cobalt]

Your logic reads right now if the hp is higher than 1, hide health bar.

[trim matrix]

i want it to be hidden and only show when a health point goes up or down

but, when the players health is only at one, i want it to stay on screen and play the flashing animation, but then go back to how it was when they increase health

[dusky cobalt]

First of all, if you post a screenshot, you can also show your tabs so we know exactly which class the code is in (so we don’t have to guess).

Second, try to arrange your Blueprint nodes more neatly so it’s easier to read. I know you’re prototyping, but it’s a bad habit to just connect things randomly (look at your True/False pins crossing—it makes it harder to follow at first glance).

Third, get familiar with breakpoints and the editor debugger. You can see live what’s happening on the graph as you move your character, so you’ll notice things like:

“Wait, it’s already 0 HP but this got executed?”
“Why did this trigger if I’m at 2 HP?”
“Why did this execute so late when I’m already at 3 HP?”
Fourth, in the situation you have now, the event is set to execute in 2 seconds. So something might have happened at 0.5 or 1 second, but because the event already fired, it still gets executed with a delay. That’s why you’re getting the output you see.

Lastly, it’s really good to sit down and write a “recipe” in plain words, then go step by step, checking if each part is in your code or missing. Make sure your recipe isn’t just “Bake cake”; instead, it should be more like “Add flour, then mix; if mixed, add salt,” etc.

[trim matrix]

i have been going through my code tho, thats how ive gotten it to this point lol

[dusky cobalt]

It's funny you didn't even fully read what I wrote

xD

[trim matrix]

i did, but ok

[civic quartz]

Am I correct, that there's still no Blueprint only solution to read parameters from Project Settings like "Use Hardware Ray Tracing If Available", so I still need to make a C++ function?

[tough badge]

So I saw a tutorial on a guy who uses a procedural mesh to to make a grid for a grid-based game. I was wondering how a non-actor based grid even works? Does anyone know of any resources on the topic because I'm struggling to come up with ways of doing, for example, pathfinding on a grid like that

[dusky cobalt]

Non-actor grid is just lines, rows and columns, vectors, and a bit of math. There are 2 OK videos about it, although they’re very basic and you’ll have to build on top of them and adjust them to your needs:
https://www.youtube.com/watch?v=DwPHsLJv5Gw
https://www.youtube.com/watch?v=Q4AOmT9aOEM&t

The first video is part of a bigger tutorial about building placement. The second video is focused just on making a grid.

The concept of programming for a grid doesn’t stop at Unreal, and is probably well documented in other non-gamedev areas, so it’s also good to look at it from a math point of view. Good to see both sides (implementation in Unreal, and documents in other areas).

[tough badge]

Oo gotcha! I'll give those videos a look and see if I can't find more info on it elsewhere. Thank you!

[languid hemlock]

I’m trying to understand how Data Table Row Handlers work. I want to create an array variable to store my initial inventory items. To do this, I need to enter a Data Table Object Reference for each item. Does this mean that multiple Data Tables will be held in memory, or will only a single Data Table be referenced regardless of how many items I add? Shortly, i wonder if that affects optimization.
Sorry if this is a dumb question 😬

[dusky cobalt]

Good start to see how it's done. Your own implementation can use a bit of it and add to it make some changes. Also after you got it how it's done in unreal I would also even check how someone did it in other engines (because C++ C# will follow the same logic) and other engines / areas might have this covered in a more advanced way.

[tough badge]

Oh for sure. I initially got interested in it because of Epics Cropout sample project had a purely vector based grid and I had never tried that before

I appreciate your help!

[dusky cobalt]

Doesn’t matter how many times a Data Table is referenced for memory—it’s the same whether it’s the first or second time. What really matters is what the Data Table is referencing later on and whether those references are already in the game, or if they will still take up memory even though those classes are not yet spawned in the game.

[barren tangle]

hi, do you know if the Lerp is a function that to be executed inside a loop?

i need help i guess

when i press UP or Down i want to make a smoth rotation of my character

i try with a Timeline

but the issue that i have is if i put 3 timelines

the fact that they can be triggered at the same time (meaning before one complete) it's an issue

also i don't know how i can recenter my character, when i stop pressing the button

so for me it should go forward when it's pressed and backward when it's released but should act same with both direction

[surreal peak]

The issue is simple: When you take damage it shows the Widget, and the Timer of 2 Seconds starts.
When you take damage again within those 2 seconds, you only start the Animation due to being now on 1 HP.
You need to also cancel the timer that is still going.

That's what the TimerHandle is for that the SetTimerByEvent node give you.

Save it to a varaible and then Clear the timer when you start the Animation.

[trim matrix]

i fixed it a differnt way already

[surreal peak]

Oki

[trim matrix]

i made it so if the player has only one health, a bool is set, and it makes the ui always visible so even if the player hits a hitbox in the time the timer is going the ui will stay on screen, since the player wasnt getting damaged twice only the uiwas fucked

[surreal peak]

You'd need to handle this in the Tick function of your Actor.

[barren tangle]

it's a bad idea to try to do it with Timeline?

[surreal peak]

You can do it with a Timeline too, but as you mentioned you'd need to ensure it stays one Timeline.

Otherwise it can play multiple different transitions.

[dusky cobalt]

Probably the best way if you not plan on implementing more than 3 health, just make switch on INT and provide what exactly needs to happen on each int individually.

[barren tangle]

and that's not good

[surreal peak]

Yeah, but it should be fine using one Timeline, or?

Timeline just needs to spit out an Alpha Value that goes from 0 to 1.0

And the 3 different options you have then set a Start and a Target Value.

And then you lerp in the Timeline from Start to Target with Alpha coming from the Timeline.

[barren tangle]

ChatGPT told me that using the tick of actor it's not dangerous for those kind of calculation. is it correct? because it's to rotate the character, if i have 6 character doing the same? I'm not yet a profiler guy (when i try i don't understand anything)

so i try to limite to overload all tick even

[surreal peak]

Things that have to update every frame are totally fine to be placed on Tick.

Especially something as simple as the updating of some rotation.

The Timeline is also driven by Tick anyway.

[barren tangle]

yes but during some timeframe limitation, the timeline duration, that is why i lock the logic into a on time trigger event, instead of a loop

ok i will try again just with the alpha and lerp inside the tick

[surreal peak]

Again, you can do it with the Timeline too if that works better for you

I don't see the problem with the Timeline atm.

You shouldn't need 3 Timelines.

[barren tangle]

i don't find the logic with the timeline 😄

how many timeline should i have, how should i act with them

that simple process is difficult to handle 😄

because if i have 1 timeline for the 3

i will jump from up rotation to bottom rotation

[surreal peak]

Depends on what you want to do tbh. You have 3 direction, Up, Center and Down.
I assume you can go from Up to Center or Down directly, right?
And I assume you can change direction while the value is going from one to another?

[barren tangle]

yes, i just want to rotate smothly between the 3

[surreal peak]

Should the transition from Up to Center take the same time as Up to Down?
Should it take the same time if you go from Up to Center and in the Middle of that transition change it to Down?

[barren tangle]

if i rotate up and press down i want to go from the up rotation to the bottom roation

[surreal peak]

Right, then the Timeline is actually not the right thing I guess.

Then on Tick makes more sense.

It's pretty simple, I can show you how in a minute.

[barren tangle]

yes please

[kind estuary]

My collision when colliding with an enemy sometimes makes the unit go below the floor (physics)
Even though the floor has collision...

Is this a typical bug, or im doing something wrong?
It doesnt happen always only sometimes

[surreal peak]

@barren tangle

That should more or less do the trick.

Idk what values you want to set the Direction float to, so I left them 0.0 in all 3 cases.

But this should ensure that it interpolates from Current to Target, so if you change Target at any point it will start interpolating the current value to it.

And you then use the Current value to do whatever you need to do.

[barren tangle]

hooo

i try that 😄

i will try yours because it seems to be more easy to understand

[surreal peak]

Could be a typical bug. Physics is freaky. Idk if the "CCD - Continious Collision Detection" boolean still exists on the Collision components but if it does, try setting that.

Where did that #multiplayer question go?

[kind estuary]

the unit is sometimes projected below the floor, as if the floor is porous...

it only happens sometimes

but when it happens the unit goes forever down

[barren tangle]

Thanks it's perfect!! i didn't know that FInterp to Constant node!! it's really usefull$

[solar badger]

Hi all,

Orient rotation to movement appears to be set to true, use controller yaw is unchecked, yet in some cases my character does not Orient their rotation to movement.

Any thoughts?

[barren tangle]

print the rotation movement + print the the code that you think update the rotation

[solar badger]

The code that updates the rotation (to orient rotation to movement) prints true

But the character does not orient their rotation to movement

[barren tangle]

i had the same issue some moth ago.. but i don't remember how i fixed it 😄

and even today i have change my approach

but i saw that it was updated

don't think 360 was the default value

[solar badger]

Mine is set above 360. It doesn’t appear to be a rate of change problem.

[dreamy mountain]

anyone got any idea why this doesnt work?
https://blueprintue.com/blueprint/sbwq0sdw/ - check for direction

it was working fine until it wasnt

[trim matrix]

why does duplicating a blueprint break it? when the nodes are the exact same in each 😭 didnt change anything. and the original blueprint is working just fine with the setup there

[dreamy mountain]

im using it as a child actor component on the arcade machine base blueprint, i didnt touch shit and it just broke

all of that code was working beautifully like an hour ago

[dry hatch]

Hey I'm having this problem with a knock back system for my 2d pixel art game. I want the enemy to be launched backwards, but the way I set it up it will only launch them to the right side of the screen, is there a way i can get the direction of the enemy character to launch them the opposite direction? Any help would be greatly appreciated

[dreamy mountain]

i think i know whats broke mine, nevermind

[barren tangle]

a dash, there is the youtuber Cobra

that help to create a dash system with C++ for blueprint to launch character

very usefull

[cobalt plover]

Not sure of the best channel to ask this -- when using Gameplay Cameras, is there a way to get the current blend weights between a transitioning camera?

I'm looking to get them into the character BP if possible.

[dry hatch]

I'll try and find that video thanks!

[dusky cobalt]

It's the same thing as before. In your logic if your widget is already created, you don't add it to viewport. So there is nothing to remove. If it's valid you skip Add to Viewport. Also because you are cross using the variable UI from ''Set'' node, which in case of valid UI is not executed, means it's probably nullptr. Stop cross using variables. Copy and paste it. Rules is simple: new node, new variable node (even if it's next to it and it's the same).
So to fix your problem just grab Get UI and plug it to Remove from Parent.

Also you still didn't get familiar with editor debugger which would make things much easier for you to find ''Why''.

[trim matrix]

i sat here and breakpointed it. the only one that had an issue was the remove from parent 😭

[dry hatch]

Do you remember what video of his he talk about this? I can't find it

[trim matrix]

your fix, ive tried multiple times lol, and shouldnt have to fix since it already works perfectly fine in the other blueprint

the original sign is working, but copying it, even using new variables, dosnt change anything

[dusky cobalt]

Print some strings here and hereto see ifit's even getting called at all. and where did you add breakpoints?

[trim matrix]

i added them on the nodes after setting is busy to true

[dusky cobalt]

and its getting executed but gives error? and the widget doesn't dissapear or itdoesnt even appear inthe first place?

also show your current code and breakpoints

[trim matrix]

the widget dosnt appear in the duplicated one, but it works perfectly fine in the original,

[autumn pulsar]

Is there a way to make a widget invisible to the player that's possessing the pawn?

[faint pasture]

how is the widget created to begin with?

or do you mean widget component which shows a widget in the world

[dusky cobalt]

did you remove adding widget to viewport?

[trim matrix]

u can see what is there?

[subtle ocean]

Hi guys ! Is it possible to add notification to a niagara system ? (quite like there is in animation montages) ?

[dusky cobalt]

All I know that yes it's possible but cannot tell you how.

[past hull]

hello, can someone help me understand why my NPCs are falling trough the floor please ? I was playing around with the collision channels but I have broken them 😦

[autumn pulsar]

I have an actor component that spawns a widget component

https://i.imgur.com/jhFASFu.png

so it should be owned by the actor

and I meant a world widget not a HUD one

[dusky cobalt]

so get component by class, get healthbar widget, set visibility to collapsed?

[autumn pulsar]

well I guess where I'm struggling is getting the current player viewport

err

you shouldn't be able to see yours, but others should be able to see it

[dusky cobalt]

oh its multiplayer?

[autumn pulsar]

no, but you can swap possession

so I need to check if it's owned by the local player I guess?

[dusky cobalt]

so who is othersif its not multiplayer? 😄

[autumn pulsar]

Just kind of fumbling through the logic

I guess I'm not sure how to get the local player controller to see if the pawn is possesed by the current player

[dusky cobalt]

if you posses next things that doesnt change which player you are

[autumn pulsar]

yeah I get that

[faint pasture]

just do that or don't do that based on if owner is locally controlled

[autumn pulsar]

get owner doesn't seem to have the "is locally controlled" function

I guess I have to cast to pawn?

[faint pasture]

you already are doing a cast which at least includes pawn so just do the check after that

ARPG_Character is a pawn

[autumn pulsar]

I was going to do it in the health component I was adding, so I wanted it to be more generic

oh hmm, AI controllers also register under "locally controlled"

[dusky cobalt]

just so you know, if AiController controlls pawn, it's owner is not Player Controller that you plugged when you spawned it, i learnt hard way myself 😄

it overrides the owner and AiController is owner of that pawn

[sweet jetty]

hello can anyone help me i am making a multiplayer game i have multiple different character blueprints and want to spawn a random one when the player connects

[subtle ocean]

Okay I found a workaround ! thanks for helping, hopefully this knowledge might help you in the future (?) https://www.youtube.com/watch?v=aA_8NLzbUTA

[autumn pulsar]

You're kind of asking for the moon in terms of implementation, but you might be able to make an array of classes to use when constructing the actor https://i.imgur.com/uFrY70H.png

[subtle ocean]

The idea for me was to set up an "Export Particle Data to Blueprint" on particle spawn (my explosion). I then link it to my blueprint thanks to user parameters, then, when I receive the data package, I don't do anything with it but I just call the function I implemented.

This is is probably shady information but let me know if you want deeper explanation

[autumn pulsar]

maybe not use the spawn actor mode

[dark drum]

I believe there's an 'owner no see' option on components. I'd imagine widget components would have it as well.

I'd imagine just enabling it would do what you're wanting.

[dusky cobalt]

Thank you! That is interesting approach. You didn't find anything built in the particle or this is actually the way to hack it?

[subtle ocean]

Actually there is a cleaner way to do it with "Niagara System Data Channels" but it is also way more complicated, and is mainly meant to spawn new NS in case something happens for the first one (collision with environement for example). NSDC is a VERY huge performance gain (compared to spawn at location), but is also very low level to use, and require high knowledge of the engine and niagara data package (which I don't have after 2 months using the engine u_u)

NSDC is for communication between niagara system to an other Niagara System, but could also be used to blueprint and from blueprint to trigger specific event in the Niagara System implementing the NSDC

I don't know much about its utilisation though. It look super powerfull but also very specific and complex to use, which is why I prefer my workaround (my issue was only about my NS send a notification to his parent, not building a whole factory for a NS)

[dusky cobalt]

Haha, makes sense, good that it works 😄

[faint pasture]

override GetDefaultPawnClassForController in GameMode

[misty coyote]

Guys! need some help with ragdoll. Once my ragdoll is finished, I set the actor location/teleport to a new point.. It seems that during the ragtime the camera keeps moving. So when the actor respawns, there is a disconnect between camera and player

I tried to disable input on death, but this doesn't seem to fix it

[opaque mauve]

hello, anyone have any experiences with the mirror control function blueprint?

for some reason when i use the mirror control, my IK hand twisted in a weird way

althought it behaves like a mirror(the translation/rotation), but the starting position always inverted like in the picture

seems to be twisting other bone too

[autumn pulsar]

That was the first thing I tried

but it didn't seem to work

[sweet jetty]

im unable to move due to enchanced input mapping when spawned how do i fix this ?

[solid needle]

really confused

[bold sluice]

Trying to make a health bar progress bar (Or, rather, fix the one I've had for a month that randomly broke).

Using this code, for some reason, it keeps outputting the progress bar result at 1.0, instead of any other value, no matter how much damage the character takes, would anyone know any sort of fix?

[solid needle]

i make a convert seconds to day hours mins thing

the values print as normal

when i set it as a value, it completely breaks

just sets to 0

prints numbers correctly

when i combine it into a data time struct it goes to 0

i dont get it

[bold sluice]

I've checked the health values, those aren't the problem. It's just the UI that doesn't properly update

It was working perfectly a month ago, it just randomly broke when I converted the health variables on the BP_ThirdPersonCharacter to that of a component's health variables from the BP_ThirdPersonCharacter

[dawn gazelle]

A Date Time is a specific date. You may be wanting to use a timespan which is just an amount of time.

[solid needle]

right

so replace my "date time" with "timespan"

[dawn gazelle]

You may need to change your "Average Time" variable to a TimeSpan and you can also use a "Make TimeSpan" node to populate it.

[solid needle]

sorry forgot to thank you, thank you it works :)

[autumn pulsar]

If you clear and invalidate a timer, does the event it's supposed to execute not get executed?

[frosty heron]

Well you clear and invalidate it so it won't hit the event

[subtle granite]

So Ive been fooling around a bit with unreal, blueprints and such and getting familiar with the engine itself, I recently watched a tutorial and Ive edited the BP from the tutorial a bit but the only issue I have ran into is that the camera occasionally will go into a mesh, Ive tried changing a line trace to a sphere trace to see if that corrected the issue but it doesn't.I used breakpoints but everything seems to be firing correctly So I assumed it may be on the logic. I'm pretty knew to this and am really trying to get a grasp for how to go about fixing this. Any help would be awesome!

[frosty heron]

@subtle granite it seems you uncrouched when there is a roof on top of the character

go to your crouch function and do a trace to determine if you can crouch or not

[median plaza]

Hi All,

I am trying to record gameplay in LyraStarterProject using take recorder… I have added Player as a Source and recorded some footage. While the recording is being done, its failing to save the recorded sequence with the warning:

Warning: Can’t save ‘…/Takes/2025-02-18/Scene_1_25.uasset’: Illegal reference to private object: ‘StaticMeshComponent /ShooterMaps/Maps/UEDPIE_0_L_Expanse.L_Expanse:PersistentLevel.BakedStaticMeshActor_C_UAID_E04F43E623D4FEF700_1435396366.StaticMeshComponent0’ referenced because it is an archetype object (private object belongs to an external map).

Can anyone please help me fix this…

Thanks!

[subtle granite]

Wouldnt that be this though? Sorry for the extra questions Im just really trying to soak up any knowledge I can!

I originally had used a line trace by channel instead of the sphere trace by channel.

[boreal saddle]

I want to create blueprint system for summoning a flying mount from a third person character, does anybody know of any good resources for such a task?

[topaz condor]

can someone here help with something, i followed this guys tutorial https://www.youtube.com/watch?v=5nMKEKV0acI&t=203sstep by step on adding steam listen servers to my game and it works perfectly in PIE but when i go to stand alone and click create session it goes from main menu to thirdpersonmap back to main menu

[tropic token]

how do you add custom category for BP type here?

And maybe it's possible to hide some standard ones I don't need for particular type?

[surreal peak]

I had code for that once.

Needs to be done through C++ iirc.

@tropic token

[tropic token]

is it some kind meta information parsing extension?

strange that it's not standard thingy 🙂

should be very usable by artist folk

[burnt rose]

Hi guys, in UE5.5 there is no target arm length under spring arm details. May I know how to change target arm length now?

Oh I found it, my eye is blind 🙂

Never mind.

[dry sleet]

It is pretty strange, but yes, sadly it's C++ only. Here's a guide on how to do it:
https://zomgmoz.tv/unreal/Editor-customization/Custom-Property-Editor-Sections
An alternative might be to use this plugin:
https://zomgmoz.tv/unreal/Plugins/zomg's-editor-addons

The plugin does not allow you to add those section buttons, AFAIK -- but it allows you to sort the details panel so that your categories end up at the top.

As much as I like that plugin I don't think any option is ideal -- hopefully Epic will make it easier in the future because the amount of clutter in the details panel can get ridiculous.

[tropic token]

yea, it's very project specific. and for my project, for level designer, 100% of standard properties are junk for several common objects. it's painful to dig them out

[dry sleet]

yup yup -- I find myself using the Favourite property option more and more

but that, too, is a pain

[barren tangle]

what you show me yesterday is just amazing 😄

all of that just replaced by

lol

that's the issue with blueprint there are to much usefull blueprint that we don't know 😢

[cobalt lynx]

Any idea why I get empty texts on the random bot names? The Array has 100 entries...

[maiden wadi]

You would need to debug it. Not enough info here. If there are 100 entries in that BotNames array, and you are 100% sure of this, then you've done something wrong with it after passing it to that function.

[surreal peak]

Sort of yeah. It's an Editor Module on our project that calls FindOrCreateSection on the FPropertyEditorModule when it starts up.
And to make that configurable we added a DevSettings class where one can configure the Sections and set them up.
Works most of the time.

[tropic token]

but it's not open source I guess? 🙂

[surreal peak]

I would need to copy paste this all in here, as it's part of the project. You should be able to find similar stuff on the net.

[tropic token]

okay, thanks

[surreal peak]

It's really not much, you should already be 80% there with just the two things I listed.

[true valve]

I tried cull distance volume on my actors. How come it's not working?

I have actors with some static meshes.

[cobalt lynx]

Nope. Entries Exist and If I add a manually random string it also works correct

[tropic token]

works like a charm. thank you so much 🙂

[dry sleet]

Nice! Thank zomg :D
