blueprint

[last peak]

if you create a new object collision channel for the enemies you could do something like this

[maiden wadi]

You still don't want to clear at the end of this one trace. This is one trace out of many that run during the montage. The hit array needs to persist through all of these traces.

[last peak]

Well each hit should deal dmg ?

[maiden wadi]

They are running these traces from a montage tick. Each swing is a montage. Each swing has many individual traces. So you don't want to clear the array each trace, but each swing.

[last peak]

hm but why tick ?

wouldnt a montage with a notify be better ?

ye if it runs on tick you need to keep the array

and clear once the montage ends

[maiden wadi]

Even if you set up multiple notifies on the same animation you wouldn't want to clear it until the end.

[last peak]

You would if each swing should hit all the actors

notify - hit everything infront - clear references
next notify - hit all actors

[wispy mulch]

Yeah so I made another interface function called sword attack end, called at the end of the ANS

all it does is clear the "enemies hit" array

and now it works!

thank you!

[eternal marsh]

Can anyone eli5 why I would use a blueprint interface or a blueprint component and why I would decide to use them together? I have probably watched 10+ hours on the subject and I feel like some obviously simple concept is not clicking.

Is an interface as simple as this happened and a component what do I do with it now?

[spark steppe]

that's a good first, and last, question for ChatGPT

the short version

a component is used to share logic between actors

a interface is used to... share the same interface between actors/objects, while the logic has to be implemented by everyone that wants to support a interface

[eternal marsh]

But they don’t have to work together. I think I am confused when I would use one, the other, or both.

I guess reusable logic is the component.

I guess if I am using a complicated component that can send and receive messages why I want to add a layer of interface to everything g as well.

[last peak]

Use the interface if you want to do something special with the object
Use the comp if you want to do the same thing

If you pick up a item you want to destroy it, always, for all actors
Pickup - destroy actor
This fits well into a comp

If you want to interact with it the interface is better
Interact with guitar - play sound
Interact with tv - turn on
Interact with Fridge - open

[spark steppe]

i think i can count on one hand how many times i've used an interface on a component

that's rarely necessary

[eternal marsh]

So let’s say I have a bullet hit an object

I want to
Effect health
Calculate angle of incidence
Determine if metal bullet hit rubber
Spawn corrrct sound and vfx
Determine if it should bounce again if it’s a laser.

Etc

I would structure that with an interface and logic it with a component? Sorry. I appreciate the replies.

[last peak]

No

[eternal marsh]

Ok. Maybe it’s the tutorial I watched that is slipping me up

[last peak]

Components always play the same code
While with a interface you are just calling 1 single event and then you have to implement your own unique code for each of these events

[maiden wadi]

At the end of the day, interfaces are only good for patching stuff that cannot be compositional or inherited. Things where you can't share a base class or put a component on it.

Interfaces are not systems. Systems have state. Anything that needs state should not be an interface but can use one.

[eternal marsh]

Yeah. In the video I watched they called the component functions in each interface function to complete the logic. It might be just over complicating the process

[maiden wadi]

Ew.

[eternal marsh]

Thanks for the info all. Much appreciated.

[wide beacon]

is there a way to have y bp spawned lock on circle not clip through the mesh? its a widget thats attached

[frosty heron]

You can render to screen

Instead of world

[true valve]

Which is better?

[sturdy sorrel]

does anyone know why the apply damage built in function would randomly change the damage number being fed into it into 0 after a few attempts?
basically all im trying to do as of right now is as soon as the player is overlapping the target it sets a timer = to the attack speed of the player and ever time the timer goes off it applies damage.
Then whenever the target takes damage it divides it by 10 sets the for loop = that number then iterates through the loop to spawn that many objects.
This works randomly from 0 - 10 times in a row then suddenly the apply damage stops working ive placed print strings everywhere and have determined the damage going in is always 100 the damage going to the object starts at 100 and suddenly switches to 0 which also causes the any damage event to stop firing however the timer is still going off on the correct interval so I am lost as to what I am doing wrong at this point

[crimson briar]

I don't see anything straight up wrong with this code. Are you sure damage is not changed by something elsewhere?

[sturdy sorrel]

yes I have figured out why its not working just trying to figure out how to actually fix it now lol. So I discovered it was breaking because its touching 2 objects at once the one im colliding with that spawns the other objects and the other objects themselves as soon as I touch both at the same time it will break the apply damage call because it cant handle the multiple object collision so im trying to give the player two collision boxes now so one only collides with my spawning object and one only collides with the collectable objects that are spawned however im still having troubles getting that to work properly

Ive gotten it to the point where the spawning code always works im just trying to get my pickup code to work again with the new collision box I am using

[crimson briar]

Oh, so it is the player damaging the boulders with an overlap.
One solution would be to make an array of boulders or actors if you don't need the boulder type. OnOverlap add the overlapped actor to the array, on overlap end remove it.
In tick or on a consistent timer call apply damage for each entry in the array.

And I'm not sure what do you mean by collision colliding with other stuff - you have a cast there, so objects of a different type shouldn't interfere with it

[sturdy sorrel]

yeah so basically if the player is in the boulder hitbox which is infront of the boulder because its played on a 2d plane but is 3d it starts the timer which is equal to the attack speed of the player which will eventually be upgradeable and what not but everytime the attackspeed rolls over it applies the damage to the boulder the boulder then takes that damage and determines how many pebbles to spawn which the player can then collect to raise their pebble count with that particular rock to buy upgrades sell to buy gear (all eventually trying to work out the core gameplay stuff first started on it today) etc etc.

so I got it to the point where it keeps spawning when im within the hitbox but now i cant pickup the stones like I could before which is what I am now trying to fix by using a second collision box on the player dedicated to just interacting with the pickups so that eventually the player could increase their pickup range

I was originally handling the pickup code of the pebbles in the pebbles event graph by checking if they were overlapping with the player which led to the issues of the spawning not working

now instead ive shoved the same code that was being called when the pebbles were overlapping with the player into a function and then check if the players new box is overlapping with the pebbles and if so I call that function which should increase my sandstone pebble score at the top by the value of the pebble and then destroy the pebble. however thats not working and i am currently trying to figure out why haha

now got it partially working now it appears to work in editor but im getting runtime error galore once i close the play preview about the pebbles being spawned trying to be accessesed but they arnt valid because they are pending kill or garbage

and fixed that with a simple is valid check before running the picked up function huzzah stuff works I can go to bed happy instead of pissed and confused lol

[crimson briar]

You shouldn't need two collisions for this, there are other ways to distinguish what overlapped with the collision - like changing the collision channels, adding custom channels, using a class comparison like IsASoft instead of casting (in case you don't need the custom actor functions and only want to call something generic like destroy or apply damage)

But if it works, great 👍

[sturdy sorrel]

I did add a custom collision tag so that pebbles dont collide with eachother and I just added that to the first collision that interacts with the boulder and I think overall having two might end up making it easier down the road when I want to increase the reach of the character and the pickup range of the character I can just scale each individual hitbox in size instead of check if objects are in the hitbox and within a specific range to attack boulder or to pickup pebbles

@crimson briar thanks for being my rubber ducky and letting me bounce ideas and consume solutions off of you

[crimson briar]

I didn't help much but no problem

[normal raft]

is there any reason why i should not add a custom function such as for loop with delay to standard macros ?

[dapper acorn]

what's the difference between binding an overlap event to a collision component vs right clicking and adding the overlap event? I'm struggling to find anything in the documentation. Attached are the two things that I mean

note that I renamed the binded one

[glacial forge]

Hi everyone

I have this mechanic of pushing cart around a spline i used warp motion than with a small delay attach component to component node to attach the player to the active location
From the video you can clearly see the problem i'm facing the hand kept swinging becouse of the walk cycle animation, how can i attach the hands to the handle??
Knowingly i tried using two bones ik node and it didn't work and also CCDK too
And thank you

[scarlet root]

None.

The binding binds an event (using CreateEventalso binding in external Actor) to the Delegate/Dispatcher
While the Event you add is the same Dispatcher/Delegate - automatically implemented /Bound

You normally use Binding to Bind the Event occurrence to an Event/Function in a different Graph - or different Actor, or binding multiple events to the same Dispatcher/Delegate, to fire all at once.
While the Event implementation is in the own Graph only.

[lethal pollen]

I want to make the speech bubble to face the camera always (maybe making its forward vector points to the camera always). I'm using the character from the TopDown template. How can I do it? I have tried this, but it doesn't face to the camera.

Thanks!

[scarlet root]

You calculate the LookAtRotation from the WidgetComponent World Location, to the Camera WorldLocation, and rotate the Widget Component accordingly - Every Player Movement and every NPC Movement (not in a Tick!!)

[lethal pollen]

So, my code is right or wrong?

[scarlet root]

I don't know the reason you get the child component of the camera.. since "Camera" should be the camera itself..

and you should get the WorldLocation of the SpeechBubble, not the Actor holdin git.

Since the Actor location can be different to the Bubble.

[lethal pollen]

This code doesn't make the widget to face the camera.

[scarlet root]

cause you set the relative rotation - not the world one..

[lethal pollen]

This code neither.

[scarlet root]

Relative rotation also takes into account the actor's/ parent's own rotation.. which offsets your rotation again..

World Rotation is always based on 0,0,0 - not manipulated by the parent/actor

[lethal pollen]

This code makes the widget face to the camera. Thanks, @scarlet root

[dapper acorn]

This is good to know, thank you
I only really ask because the binding version just didn't work for me and I have no idea why, ha

[dapper acorn]

but now in a completely new project it does work...

must be something really wild that I've done in the other one that's causing it to break

[scarlet root]

If you add the Event implementation AND binding inside the same Actor.. it sometimes can be confused and only call the event, not the binding..

[dapper acorn]

but that's the thing, in my other project, adding just the binding (with the overlap event attached to it) it just didn't work

I'll check it again to see if I've got another random overlap event that it's getting confused with

it's almost certainly a user error

[dense hinge]

Hiya! I have a loop of traces. Is there a way to get the end location of the last trace in case none of the traces hit anything?

Edit: Nevermind, got it. Apparently I just needed to say it out loud for my brain to figure it out. Got the end position location from the trace, and the filter out by the loop's last index

[scarlet root]

https://tenor.com/view/classic-youre-classic-thats-classic-haha-classic-so-classic-gif-4807968

[dark drum]

The one you create by right clicking on the component breaks if you ever call Unbind All on it. There's also no way to rebind it to make the node useful again during runtime.

I tend to go with the following, if an event dispatcher can be bound and unbound, go for a manual binding with a custom event. If there's no plans to ever unbind all, such as the overlap events. The other is fine.

[umbral venture]

Hey 😄
i started up my project after being away over the weekend and now every node added their own middle node (the dots you get by doubleclicking the lines usually) twice.
Did i click something odd or is this mayhbe a plugin?

[scarlet root]

maybe a plugin error of your theme-plugin, adding Reroutes...

[umbral venture]

hmm

[scarlet root]

once had this with electronic Nodes, too

[maiden wadi]

It's because your nodes have forcefields and it can't get through.

[umbral venture]

can i fast remove all the rerouts?

i rarely use them anyway

[scarlet root]

nope - one by one to not lose connections

[maiden wadi]

There's a hotkey for it.

Uhh..

[dapper acorn]

so hilariously the reason why my manual binding wasn't working was because I had put the bind node after a "true" section of a branch, which had a 50/50 chance of firing
I've put it before that branch and now it works fine (obviously)

such a trivial thing!

thank you very much for the use case explanation. That's also a thing I was wondering about (when you'd go for binding over just right clicking)

[scarlet root]

reroutes normally are used to route the wire in ways, normal bezier do not..
And to keep your very long wires rendered on screen edge, to not flip around when being rendered again

[lethal pollen]

I have all of these static meshes that I've placed in a level. Is there a way to create one blueprint actor with all of them?

[maiden wadi]

Select them and shift+delete

[scarlet root]

Select them all - and at the top, hit the Blueprint Button (3 squares with wires inbetween) and select Convert Selection to Blueprint Class

[umbral venture]

thx! that will work for me:)

[scarlet root]

alternative - Use Prefabricator
Free Prefab Plugin

[umbral venture]

i fixed it 🙂

[lethal pollen]

Thanks, @scarlet root

[spark steppe]

also important to use harvest components option

instead of the default, which creates a bunch of child actor components

[dusky cobalt]

You might also want to use WidgetComponent for that and display it on Screen.

[rich prairie]

Hello everyone. I am getting rather frustrated about destruction system. In ue4 it was so easy to destroy actors and spawn loot or whatever you wanted it to do, through blueprint. This is my best attempt, and it is horrible. It doesn't always destroy and I then need to walk into it, for it to fall apart. How can I do this in a better way?

[scarlet root]

I think the best is, to ask this in the https://discord.com/channels/187217643009212416/966517078834151484 channel.. since they are more specialized in there..

[rich prairie]

I will do this. Thank you 🙂

[dark drum]

Yea, functionally they're the same. Not sure if the hard bindings (you create from the right click menu) breaking with the unbind all is a bug or not. Its the only reason I choose to use them in different situations.

[floral stump]

where is the float param? 🤔

[frosty heron]

the custom rpc seems like passing a struct too not UObject. Are you sure it's the same function? try to re-drop the functioon call.

@floral stump

[floral stump]

re dropping fixed it 😄

[frosty heron]

out of date node.

You don't work with bp a lot? it's quiet a common gotcha.

[floral stump]

yeah I use it only for prototyping

99.9% c++

Working on vehicle already? is the shooting bit done?

[floral stump]

yeah figuring out that FGear Physics, its a complex system but very robust

it was made for UE4, I updated its API to make it supportive for UE5

@dawn magnet sorry to ping you, did you manage to get "Bone Driven Controller" to work?

[normal raft]

to get the little bird right i would lerp its vector to match that of the lorry

but yep you could just rotate on it on x/y or what ever to make it align in the first place

i try and avoid these types of mismatches in the axes

its only going to make your life more difficult later basically

put the mesh in the correct XYZ in the first place

[oblique wasp]

I'm wondering if anyone can help me with a strange issue. I've done something very simple: in the Construction Script of my Blueprint, I use an InstancedStaticMesh to spawn some spheres.
At some point in the game, I need the location of a specific sphere, so I use the Get Instance Transform node to find it. This is where the 'magic' happens. When I draw a debug sphere at that location in PIE, the result is wrong—the red sphere appears in the completely wrong place:

However, as soon as I eject from the Player Controller... BAM! The debug sphere jumps to the correct position:

I have no clue what kind of black magic is going on here. Any ideas?

[oblique wasp]

Ok - nvm - it only affect Debug Sphere for some reason. When I spawn actor there - everything is fine. There is something wird in DrawDebugSphere thou....

hi why is this happening, the "level" is all empty except for the foliage but im using 70/73 of my veruell dedicated memory ????

GB*

whats takin all my virutell memory usage O.o ?

just being idle in the editor takes a huge amount ??

[faint pasture]

Memory is there to be used

Don't worry until it's a problem

but yes the editor is a memory hog

[steady night]

but i can barely do stuff in the level since its "lagging" while doing stuff

[lofty rapids]

whats your landscape material look like ?

[tropic token]

We're creating a component BP_InteractableComponent derived from ActorComponent. We add a method called Interact to it.
Then we create BP_InteractableObjectBase, and add the BP_InteractableComponent to it.For different types of interactions, we'll make child classes from BP_InteractableComponent and override the Interact method in those children.

In BP_PointClickController we handle the InputAction PrimaryClick. We perform a trace under the mouse cursor, check if the Hit Actor has a BP_InteractableComponent, and if so — call the Interact method on it.

guys, does it make sense in case I don't wanna do interaction system based on interfaces?

[frosty heron]

Actor componenent most likely the most used method for interaction. It can hold state.

Its weird that you create interactableObjectBase

You can just attach the interactable component to any actor.

The whole point is you dont need to worry about the owner type.

As the system is contained within the actor comp.

[tropic token]

Yea. I guess it's weird. I was thinking about if I have doors I will make base door and attach door interact component to it and then make as many doors as I want. That sounds less weird? Or best way to go is to attach door interact component to every door type?

[frosty heron]

DoorInteactionComponent? Wut.

It should just be interactionComponent

Which work for any interactable object. Regardless of their type.

It can be attached to a door, a chest, a player character. Anything that is interactable.

[tropic token]

I'm not sure. But different object can have different state of interaction. That's why different components

[frosty heron]

No you are missing the point of components.

Think about inventory or equipment.

Any actor can have it. A chest may contain inventories, an npc may contain inventories.

A door may contain inventory.

The code should be seld contained.

[tropic token]

Where do I store state and do unique interaction logic?

I mean you interact differently with door and button

[frosty heron]

Your interaction component should have the method of being interacted.

The owner can bind to that function.

And just implement what its designed to do.

A door can open or close.

A button can be pressed.

An npc can be spoken to.

[tropic token]

So the door saves its own state and logic of interaction.

I need to see how to bind function of the component. Never did it

[frosty heron]

Your interaction component can hold states such as. BIsCurrentlyInteracting, or bCanBeInteracted. Etc.

[frosty heron]

Event delegate.

[frosty heron]

The door doesnt save the logic of interaction.

Door just sets its own member. Such as bIsOpened.

E.g

Overlap with a door -> get interaction component -> interact.

Door call its interact logic (an event that is binded from its interaction component) -> toggleOpenOrClose -> set door bOpen.

[tropic token]

okay, so I do it like this

[frosty heron]

Yesss

[tropic token]

okay okay

thank you

but still. like if I have many doors, with same logic and state, it's reasonable to create base class for them, right?

this is the way? xD

[frosty heron]

But its decoupled from the interaction system. Dont mix the two.

Your interaction componemt should be owner agnostic.

[tropic token]

Yea, okay. Got it

[frosty heron]

You can have child of some door, sure. But the interaction component remain oblivious to any of these doors.

The component is just there to tell the owner, hey you have been interacted.

The owner can then execute its own logic.

[tropic token]

What about health component? It can store health, right?

[frosty heron]

Would be better if you make attributeComponent.

But yeah sure thing.

[tropic token]

Yea but. It should have health or should take health from it's owner?

[frosty heron]

The health or attribute should live in the comp.

When you need to check an entity health you just go.

Get door -> get health componemt -> get health

[tropic token]

Yes okay. Sorry for silly questions btw. Many thanks for replies 🙂

[frosty heron]

Not silly at all. Gl

[floral stump]

🤣

today encounter 2 weired things in unreal in this plugin

😂

this is why never use bp's for complex stuff

[naive sable]

I am trying to debug lag over time in my game with unreal insights, and found out that it was being caused by wait for tasks increasing. However, I cant figure out what is making wait for tasks increase. Does anyone know how I can find this out? I can also send my trace if that would help.

[eternal sandal]

does anyone know of a guide for creating a interactable desktop/terminal in ue5?

[faint pasture]

Think of your actors as bags of components with a bit of glue

the health should live in a health component

if this specific owner does something weird (like explodes on death), it can bind to HealthComponent.OnDeath and do the extra stuff

[true valve]

Since you can't use soft for DataTable Raw Handle? Including them in struct are heavy

[scarlet root]

yes
But you can have a Soft Reference of DataTable and a simple Name-variable for DataTable Row in your struct.. which is less heavy

The DataTableRowHandle simple is a

TObjectPtr<UDataTable>
FName RowName

Nothing big of a difference - even worse than doing it by yourself using a soft-reference instead of a hard one.

Like:

TSoftObjectPtr<UDataTable>
FName RowName

[scarlet pumice]

I have a BP with an instance variable to a Level Sequence Actor instance in the scene. I am getting a warning about Spatially loaded (the BP) actor referencing non-spatially loaded actor (Level Seq Actor).

The LSA cannot be set to spatially loaded, but I don't want to make my BP non-spatially loaded, as there's no point in having it loaded when I am on the other side of the map.

Am I missing something? Maybe I should be spawning the LSA dynamically in the BP?

I changed the BP to Create Level Sequence Player instead of referencing a world actor, seems to work ok 👍

[near wolf]

I'm explosing a sun angle slider to my widget, but the sun moves in steps and not smoothly. Is there a way to make it move smoothly?

[scarlet root]

if you have a sun angle of 45 and set the slider to 60, it will jump from one frame to the next by 15°..
That's normal..

At runtime, you can use a timeline to interpolate the angle switch..
This timeline has to sit in an Actor, not inside a Widget..

In the editor, you kinda can.. but not recommended.. since it involves using the editor tick..

[compact hornet]

i'm having this trouble with lumen GI. basically it takes such a long time to update when I turn off a light source. Any way to fix this?
https://youtu.be/--D96NuMVf4

[scarlet root]

Is it intended to use Lumen in your Game? or do you just use it, cause it is enabled?

[frosty heron]

interpolate current value to target value.

[compact hornet]

i use it because I have so many interactible light sources

you think it would be better to bake? there are so many objects that are hit with more than 4 stationary lights at the same time no matter how I approach it

[scarlet root]

no.. but using MegaLights (even as experimental feature)

Alternative.. you can Execute a Console command with:
r.LumenScene.SurfaceCache.Clear

Clearing Lumens light cache on drastical changes (like switching lights on/off)

But i would not use Lumen if there is other ways around it..

[compact hornet]

ok

I've been experimenting with lumen and baked back and forth

it's said that megalights would help with the limit on stationary lights, but for some reason it seems to me like it doesn't really do it for me. but i guess i should deep dive into that

[dark drum]

Its realism. 😅 When you look at a light in real life and turn it off, you're brain/eyes take a moment to catch up leaving a light spot in your vision like its burnt on.

[scarlet root]

I remember there was a Lumen Update time setting - isn't it?

• Lumen Scene Lighting Update Speed
• Final Gather Lighting Update Speed

In the Global Illumination Settings of the PostProcess Volume

maybe you can alter that too, to get quicker response

[near wolf]

something like this?

or like this

still feels like it's "laggy" or moving in steps

while using almost the logic above with "Time of The Day" - the time of the day slider works pretty smoth

but the Sun Angle not

the Sun Angle is moving in a way that feels like my fps is dropping when using it, but the fps is stable

[scarlet root]

ok.. rule 1 in UI coding:
Don't use TICK inside the UI...

Short axplanation how to achieve this:

1st: in Your PlayerController, add a new Event called "UpdateSunRotation" with a Float as Input.
2nd: Add a Timeline to this Event and doubleclick it, to open the Curve.
3rd: add two keys, one at time 0.0, with value 0.0 - And one at time 1.0 with value 1.0. Close the curve
4th: Wire the Event with the Play from Start of the Timeline.
5th: In the Timeline Body/Update, add the Interpolation, with the current Sun rotation as A, the target Sun rotation as B (B is the Event Input), and the Timeline Float Output as alpha. Set the Sun Rotation to the outcome.
6th: On Finished of the Timeline, set the Sun Rotation to the Event Float - which finalizes it.

In your Widget, On Slider Value Changed, Get Player Controller, Cast to your PC, call the UpdateSunRotation Event.

The timeline gets called each time you update the slider and starts from the beginning.
It only proceeds the whole second and finishes, if you leave the slider.

You can adjust the play-Rate of the Timeline, to make the interpolation quicker (higher rate) or slower (lower rate)

[near wolf]

ok i'll try it now

[dark drum]

With you using UDS, I would just add a new function to it that allows you to set the 'DesiredTime' and 'DesiredSunAngle' and then UDS handle lerping the current values to the desired values.

[near wolf]

you mean to to that inside the UDS blueprint and then expose it to the widget?

[dark drum]

Yea, you're widget should only really need to call one function and specify a value. Everything else should be handled by the day/night cycle system. (UDS in you're case)

If you don't want to modify UDS, you can always create an actor component to act as a middle man you can place on the UDS actor.

[near wolf]

Not sure which one would be the least painful as I'm not really a blueprint guy haha

[dark drum]

Something like this. It would be easier to put it in the UDS system but both should be fairly straight forward either way.

The below method should also handle quick changes by the player.

CurrentTime would just be what ever variable UDS uses.

[near wolf]

Ok thanks, I'm just a little confused which one of that should be added to UDS and which one to the widget?
Also in which part of UDS as there are a lot of functions and stuff going on. Sorry for my confusion

[dark drum]

All added to UDS. The widget would just call the 'SetDesiredTime' function.

[near wolf]

ok let me try and see if I would mess up haha

[near wolf]

Not sure if I am using the wrong nodes here?

the sun angle variable is the original from UDS, the desired angle variable was made by me

[dark drum]

If the 'CurrentSunAngle' is a variable in UDS, it shouldn't have the self pin. Try removing them and dragging them from the variables tab instead. (I believe its trying to set the one in the widget which might not actually be needed any more)

[near wolf]

ok wait. I think that one is from my widget

[near wolf]

Here, but somthing is not working yet

nothing happens when I move the slider

ops one sec I forgot to pin that node

Ok it's actually moving now, but it still moves in that slow steppy way

let me record a quick video

[near wolf]

Look how smooth "Time of the day" works, but "Sun Angle" is so slow and steppy even after I used the way you told me

I'm starting to think that maybe it's just UDS issue and moving the sun angle is too heavy for performance? But my FPS is not dropping

or maybe I messed up the nodes somewhere

[dark drum]

So it could be down to the angle value itself and what it expects. You might need to lower the threshold on the nearly equal node (perhaps 0.0001) and possibly play with the interp speed.

[near wolf]

I Tried that, it moves faster, but still in a laggy and steppy way

[dark drum]

Print the angle values to see what it gives. I can't see anything wrong with the setup but it's worth checking.

[near wolf]

from 0-360 . Not sure if I connected it at the correct node, but I guess it is, if it shows those values

[compact hornet]

Thank for the help. yeah I've trested those kinds of settings as well but it mostly hurt performance without makig ut much better. I'm exploring if I should go back to baked lighting instead

[spiral rune]

Hey ! I have A problem, I reopen my project today, I was able to launch it once, but when I recompiled my build file, I got an error; when I click on "jump to node," nothing happens.
The error is :
A Child Actor Component's class cannot be set to its owner! 'dialogCharacter_C' is an invalid class choice for '/Game/PestoQuest/BP/dialogCharacter.dialogCharacter_C:dialogCharacter_GEN_VARIABLE'.
IDK whats is it, i don't have any error in any node of my bp...
If someone can help me it can be crazy

btw here is my components

[pale idol]

I think I found a bug in Unreal 5.6 blueprint:
Undo doesn't work as expected after adding components through Blueprints AActor::AddComponentByClass despite using the Transact system

Bug description and uasset reprocase can be found here: https://drive.google.com/drive/folders/1aCCedol7Pu7HQoE9gO8ssmY3kVu1xH5h?usp=drive_link

2 things I would like if possible:

• if it looks like I am using the node wrong, I'd like to know.
• if anyone has encountered this issue before, what workaround did you use?

Thank you!

[crude marlin]

The bp is corrupted bcs i last saved it in UE 5.7 and now opens the plugin with the same blueprint in 5.5. And i need to find a way for them to be agnostic of version or atleast a way for me to quickly override versioning so they open so i canr recompile and save where im working for the moment.

Hi, I have a car animation sequencer that has x and y transform key frames. I wanted to get the Z value based on the roads/terrain. The cars have physics enabled, and in the sequence, they have the static mesh component simulate physics. I was hoping on hitting play, the cars would get to z value based on collision with the road and continue moving along, but that is not happening. They hit the road and bounce a bit and stop. How can I fix this?

[frosty heron]

I strongly advice to not use child actor component. It is the most cursed entity in unreal engine. Even epic staff says to not use them outside transiet stuff like sfx.

[eternal sandal]

how can i create like a desktop on my pc that i can interact with? Please send a yt guide if possible because i couldn't find any.

[last peak]

what ?

[eternal sandal]

like doki doki literature club

[pine carbon]

Do you want it to be a physical thing in your world or just a screen?

The one in DDLC on Console, which I assume is what you mean, is just fancy UI that's made to look like a PC.

If you mean the original release of DDLC . . . that's a little trickier. Salvato was a clever bugger with how that game was made. There are no "tricks" to how that works, it's actually using your computer's filesystem. You can learn how to do it but it's not gonna be an Unreal thing.

[pine carbon]

Why does it exist?

The ONLY thing I ever hear about Child Actor Component is that you shouldn't use it.

[frosty heron]

Fail product

[pine carbon]

Eh?

[frosty heron]

Full of bugs, dont know what else to say.

Many features are abbandoned but left for backward compability.

[pine carbon]

What was it intended for, though?

[frosty heron]

No idea, probably for prefab like workflow just like unity.

[pine carbon]

Hm. Neat.

[thin panther]

it's intent was probably exactly how people use it, it was just poorly made

[pine carbon]

I don't know how people use it though. I have only ever heard it brought up in the context of "do not use this."

[thin panther]

generally speaking people don't

the only safe usage is for purely cosmetic things that have nothing that need to be serialized

but that usage is few and far between, and even still alternatives exist

[dark drum]

My attempt at trying to understand how the construction script works helped highlight why child actor components are so buggy. 😅

[sand shore]

@pine carbon

Well, speculatively, the intention may have been that you would use CAC to implement “ItemSpawner” type things- you hand place what you want spawned into the level and you can see it in editor, you can customize all the properties it will have when spawned specifically from that spawner, all that cool stuff, and then you can spawn the real actor when you want to, programmatically.

But there’s tons of ways it can break so the general advice is “hey don’t use it” because the real answer is somewhere closer to “beware the dragons you must fight” and a lot of folks just aren’t ready to take those dragons on, the dragon of reimplementing the result yourself is often smaller, and especially so if you limit the scope of what your thing does

But it’s devious as to newcomers it seems like something that solves the problem and is endorsed until they ask anyone about it

For anyone who read that and thinks “oh so if I’m really comfortable with the engine I can make CAC work” you ought to be really comfortable with engine debugging in C++ and willing to make local changes

Like a custom build

Like I would just manually make what I need and not take any chances haha

[maiden wadi]

And by the time you get it working like you want you'll realize it a was a shit idea to begin with and you'll be writing an async customizer that can read an actor's component list and mimic them with async loading and time slicing. 🤷‍♂️

[sand shore]

AND you’ll benefit from learning to do all that and feeling like a smartypants for getting it all ergonomic and “better than epic”

Like there’s no losing when you ignore CAC

[sand shore]

Ok but the real answer for “why isn’t it gone” is probably back compat

[shut blaze]

hey guys, how does one create a debug panel, to get information like player location, time of day, and also add commands like set time of day, without creating hard references or using interfaces?
(in other words: how should I do it?)

[sand shore]

You could make your gamestate able to do this. One possible way is you can make a struct that contains two string fields, and you can make an array of those structs on the game state. Every frame the game state clears the array and then every actor / component can add properties to that array, like the player could add “PlayerPosition”: GetActorLocation.ToString()

And the widget just displays them

That’s not optimal but it’s a really basic way to do this while minimizing references and interface use

[shut blaze]

I'm a bit stupid so I wanna make sure I understand right
ArrayStruct: String A and String B (idk how to label em)
Tick: Clear array
Player Tick: Cast to GameState, set array string elem

I think I got something wrong

[shut blaze]

.

[sand shore]

https://tenor.com/view/rickandmorty-showme-gif-7658980

[shut blaze]

I've got nothing dude, that Is why I'm asking

[sand shore]

Ok

It seems like wht I suggested

What is confusing?

[tropic token]

my good guys, I have cine camera actor on level, like a bunch of them. designer already configured. I want to replace them with my own type that is derived from cine camera actor. the problem is that when I replace actor, all properties are sent back to defaults. is there any way to conveniently migrate all settings from one actor on the level to the other? there's a property transfer tool but it works for assets in asset browser

[shut blaze]

"Every frame the game state clears the array and then every actor / component can add properties to that array, like the player could add “PlayerPosition”: GetActorLocation.ToString()"
I've got no idea what you mean, so every frame just cast to the actors I am interested in the information
I want a Widget panel to display all info I want, such as a player panel, world, AI, command panel etc.

[sand shore]

I mean you had it.

Every actor or component that has stuff you want to be in the widget, they each on their own fetch the gamestate and each calls a function to append a separate struct to the array in the game state

The gamestate only knows about its own array member and to clear it

Each actor only knows about its own stuff it wants to add to the list

The widget only knows about the list

You can call the string members of the struct RowName and RowValue

Does it have issues? Probably! The GameState needs to tick before any of the other actors, and the widget should tick after all the other actors

[shut blaze]

sooo I should add a bool "IsDebugOn?" so that actors know when to actually give information?

[sand shore]

Well if the game state has a function that the other actors call, that bool can be handled inside

Otherwise yeah it would save some computation for the actors to skip making strings

[shut blaze]

ah, sooo,

1. Create Debug Component
2. GameState > ComponentFunction Get Info > Game State > Widget

[sand shore]

Yeah that seems like a possible modification of wht I proposed

Do you know how to change tick groups?

[shut blaze]

that could work, but, how would I call the component from each actor

[shut blaze]

nope

[sand shore]

Darn

Idk, using an interface sounds like a much better fit

[shut blaze]

honestly

yeah

if else, then screw debug menus

[sand shore]

Why did you wanna avoid em?

[shut blaze]

heard can be a hastle to debug or scale

idk why tho

just label each function DebugMenu_Something

[sand shore]

Well ok so I like having the row structure

We can keep the row structure

[shut blaze]

GameState > EventDebug(fromBPI) > Game State > Widget

[sand shore]

Make an interface thats something like HasRowStringDescription.

The interface makes a function that returns an array of those structs, called MakeDescriptionArray.

The widget can use GetAllObjectsWithInterface and can append all these descriptions together into one big array and then it can spawn inner widgets for each row

Nothing on the game state

Nothing on random actor ticks

AND if you ever wanna reuse the interface for stuff like item inspector widgets in game, it wont feel like as much of a hack

Now, GetAllObjectsWithInterface is SLOW its really awful

But it’s perfect for debug tools

Does that idea make sense?

[shut blaze]

I think it does
so a widget that does it all
Get all objects and when you wanna update them just call the event in them

makes sense

[tropic token]

I wonder, how would you implement CanInteract on InteractableComponent?

[faint pasture]

Does CanInteract mean it can interact right now or interact at all?

[tropic token]

right now

[faint pasture]

a bool in the component

[tropic token]

okay, owner anyways know about the component, so nothing is wrong with it

you can't really decouple it further 🙂

hey how do i disable shadow culling ? when i zoom out shadow dissapears :/ ?

[flat coral]

I'm working on a keybinds menu, and that means I need on some level to map from ANY possible key to a texture of an icon for that key. What's the best way to do that?

I could make a bigass map of keys to textures and store it somewhere I guess but that seems like a Big Awful and I'm hoping there's a smarter way

This is what the textures look like

[maiden wadi]

Not sure how you would map keys to icons without a map of keys to icons. It'll get more fun when you consider consoles. Cause you'll need a data set for each console.

If you're serious about this, I'd recommend CommonUI. It already handles this.

[pulsar geode]

anyone able to help me figure out some math here?
i have a value coming from a lerp (V), that i need to find the difference of between its current value and its last value.
i thought i could just have my V minus a temp number (T) who's default is 0, to get the answer, with T being set to what V was after. so next time it was run it would be a larger V number, minus T which was the previous V, giving me the difference (N).
the problem is the code seems to be executing in such a way that T is being set to V before anything else happens, ending up with it just repeatedly being V minus its current value over and over as you can see in the print screen inside the red square.
Does anyone know a way to correct this?

[next hollow]

I mean, its right there. 😛
Your setting that temp speed multiplier before you do anything else.

You'd wanna do that at the very end, or at least after you do stuff with it

Cuz, you set the var, then print the var.
You'd want to print, then set.

[pulsar geode]

so just set it as far back as i can in the logic chain?

[next hollow]

Pretty much

[pulsar geode]

still getting the exact same error, its behind multiple different things in the timeline update, and still its being set before the subtraction is happening somehow.

[next hollow]

Hmmm.
And, your using, or caching the appends output?
Not, just dragging its line like a mile to the right?

[pulsar geode]

its was actually almost the opposite solution. i promoted the lerp to a variable but had the temp set to the lerp variable beforehand. since the default for the lerp is 0, it would always be one behind in the cycle.

[next hollow]

Is that not what you want?
The previous value, and thus the difference?

[pulsar geode]

thank you for the help though, once i knew it had to do with the ordering of what was being called, i was able to narrow it down

[pulsar geode]

yeah i was able to solve it by reversing your suggestion, thanks for pointing me in the right direction

[thorn crown]

Thats the old version, he has an updated version as well V2. which covers 5.2 to 5.7 https://www.fab.com/listings/e5f036a3-c476-40bc-9eaa-531e9617c0c5 @frozen wren INCASE your wondering about an updated version

[crude marlin]

Hello Gang, does anyone know how to solve when some blueprints seem to be breaking bcs of Unreal Versions.
I need to make sure all my demo blueprints works on any Unreal Version 5.4-5.5-5.6-5.7
But i can not find any documentation on how to solve this:

I have multiple projects and my plugin submoduled so i need to be able to test and save new changes in any Unreal version.

```The package 'MY BLUEPRINT' was saved with an newer version which is not backwards compatible with the current process. Min Required Version: 214 Package Version: 0````.

https://dev.epicgames.com/documentation/en-us/unreal-engine/versioning-of-assets-and-packages-in-unreal-engine

[frosty heron]

Use source control and create a branch for each version.

You cant have a project that just work for all version.

The plugin will depend on the version its compiled in.

[scarlet root]

CommonUI.
Since CommonUI includes the Common Input Data, which is literally what you are looking for.. Icons mapped to Keys..

[brave hatch]

I'm still new to blueprint but can anyone tell me what I'm missing here?

logic I'm trying to achieve:
get static mesh component > get relative rotation > if relative rotation Z is equal to 180 return true > AND bool so I need all three to fire at the same time > branch condition achieved for true

achieving the rings correct rotation of z 180 doesn't even hit a break point on the and or the = =

[crimson briar]

First thing you would want is to swap == with nearly equal. Not sure if there is nearly equal for vectors, but there is for floats

In general you shouldn't use == with floating point numbers

Depending how you rotate the objects though the rotation can still jump over 180

[scarlet root]

180 is veeery specific - unreal has floating errors and almoist never hits the float exactly.. So as VeraelHasta stated.. change to a NearlyEqual Condition, that has some threshold.

Next is the 180 itself.
Maybe your 180 is different to the Unreal 180.

Rotations in Unreal are not 0-360, they are -180 - 180

[brave hatch]

it's checked against the viewports mesh rotation, it's 180/360 on Z. but I'll give it an error margin

[scarlet root]

alternatively, you could Round the Rotation.Z before checking.. So you deal with integer values then.

[brave hatch]

I think the main issue is that the 'get relative rotation' is not changing it's values at all during play

and I have 0 idea why

[scarlet root]

is the mesh rotating INSIDE the actor itself?

[flat coral]

I've heard that, but would you import CommonUI just for that one function if you've already got an entirely working UI system otherwise?

[brave hatch]

I would say so?

[scarlet root]

relative means, that the rotation is based on the whole actors own rotation.. and from there, in what difference the mesh is to

[brave hatch]

rotation logic

[scarlet root]

RingTarget1 - 3 is set somewhere?

[brave hatch]

actually there's an idea use the integer instead of the mesh.

nevermind, off to mess with it more until I hit a brick wall

[scarlet root]

You should use CommonUI no matter what single function you need.
It's a recommended update to UMG and fixes some UMG problems by just being there.

CommonUI is not replacing your UI.. I don't know where this obscure rumor is coming from.. CommonUI IS Umg.. just extending it.. not replacing.. you keep your UI as before..

I also recommend using this function in a BlueprinrFunctionLibrary:

UFUNCTION(BlueprintCallable, BlueprintPure, Category = "CommonInput")
    static void QueryKeyIcon(const UObject* WorldContextObject, const FKey& InKey, UTexture2D* DefaultTexture, FSlateBrush& OutBrush, UTexture2D*& OutTexture);

void U<YourBlueprintFunctionLibrary>::QueryKeyIcon(const UObject* WorldContextObject, const FKey& InKey, UTexture2D* DefaultTexture, FSlateBrush& OutBrush, UTexture2D*& OutTexture)
{
    const UCommonInputPlatformSettings* PlatformSettings = UCommonInputPlatformSettings::Get();
    if (!PlatformSettings)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    if (!WorldContextObject)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    const UWorld* World = WorldContextObject->GetWorld();
    if (!World)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    const APlayerController* PlayerController = World->GetFirstPlayerController();
    if (!PlayerController)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    const ULocalPlayer* LocalPlayer = PlayerController->GetLocalPlayer();
    if (!LocalPlayer)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    const UCommonInputSubsystem* InputSubsystem = LocalPlayer->GetSubsystem<UCommonInputSubsystem>();
    if (!InputSubsystem)
    {
        OutTexture = DefaultTexture;
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    bool RetrievedBrush = false;

    const FName GamepadName = InputSubsystem->GetCurrentGamepadName();

    if (InKey.IsGamepadKey())
    {
        RetrievedBrush = PlatformSettings->TryGetInputBrush(OutBrush, InKey, ECommonInputType::Gamepad, GamepadName);
    }
    else if (!InKey.IsGamepadKey())
    {
        RetrievedBrush = PlatformSettings->TryGetInputBrush(OutBrush, InKey, ECommonInputType::MouseAndKeyboard, FName("Generic"));
    }

    if (RetrievedBrush)
    {
        OutTexture = Cast<UTexture2D>(OutBrush.GetResourceObject());
        OutBrush.SetResourceObject(OutTexture);
        return;
    }

    OutTexture = DefaultTexture;
    OutBrush.SetResourceObject(OutTexture);
}

This is a simple function to gather the Icon of a Key from your CommonInputBaseControllerData.

[brave hatch]

alright this doesn't work either .-.

[scarlet root]

I know.. it's c++.. But CommonUI is not the easiest to deal with in BP only..

[brave hatch]

and yes I know that's a -180 and not 180, just trust me that I changed it after the first. (because my rings rotate at -60 per activation)

[scarlet root]

again.. are the integer values set correctly? (checked with a print)

[brave hatch]

print shows they're correct

[scarlet root]

and printing after TRUE does not print anything?

[brave hatch]

this is printing after the rotation tick function, it's not even getting past the branch in the event graph.

[scarlet root]

In this pront.. there is no 3-times the same value in a row... which should happen to make your branch being true..

[brave hatch]

pardon?

[scarlet root]

180
-180
-180

or

-180
180
-180

Not the same ...
All 3 have to be the same value to return TRUE on the AND

[brave hatch]

they do not rotate independently at the moment, they all rotate at the same speed/intervals/direction

[crimson briar]

Add ABS before comparing to 180

[umbral venture]

i am making a helix made of cubes in a square shape.
is this wrong?
https://blueprintue.com/blueprint/scpsv9gi/

[brave hatch]

what is ABS

[scarlet root]

It might also help if you use a PrintText and a Format text Note to it.. using
Name of Entity {OutY}

So it prints the Y value with a name.. to make the print not a magic number..

[crimson briar]

Absolute, it removes the minus signs from numbers

[scarlet root]

{Name} creates a wildcard Input Pin in the Format text, where you can plugin any value..

[scarlet root]

ABS = ABSolute = returns the absolute positive value of an equation or number

Example:
ABS(5-10) = 5 ,even the equation is -5

[brave hatch]

that just goes right over my head I'm afraid

anyway adding absolute does nothing either.

maybe I should just give up on the = = method and just go for an overlapping collision

[scarlet root]

ok...
Print this with a PrintText and a FormatText linked into its text Input:

Ring1: {OutY1}
Ring2: {OutY2}
Ring3: {OutY3}

So you know what Ring is off rotation with your prints. Cause your current PrintString does not give much of information..

[brave hatch]

I only needed the print to show me the value, I know it's rotating

I've got a lever that activates a 60 degree turn based on which ring it's attached to, I've got all three rings able to rotate a full 360 loop without issue, I've got a random integer at begin play so the rings are always random between their possible points (this is meant to be a trivial alignment door puzzle) i just need to get the damn thing to register my desired conditions to vector the whole thing to the side

[scarlet root]

yes.. but you don't know which of the rings is off... cause your prints do not have identification informations..

And there is one off.. else you won't have -180 and 180 mixed

[brave hatch]

ignore the misalignment of the mesh, it is 180, it's just the basic cylinder mesh for UE5 is off center for whatever reason

[brave hatch]

no. they all rotate the exact same direction.

[scarlet root]

maybe visually.. but as your prints return.. one is wrong

[brave hatch]

no it's not

[crimson briar]

It is not wrong, the number can flip between + and - when it is on 180

[brave hatch]

that's all three rings on a different position and there is no negative in it

[crimson briar]

Due to how Unreal handles rotation

[brave hatch]

it's on relative Z axis

[scarlet root]

shitty gimbal lock 🙂

[brave hatch]

even so, you guys said an absolute would disregard the negative

[scarlet root]

So the setting of RingtargetX should be:
RingTargetX = abs(round(RingX.RelativeRotation.Z))

[brave hatch]

well, I have an absolute

[crimson briar]

Yeah, comapring it to be like ABS(-180) is nearly equal to 180 should return true for both -180 and 180

[brave hatch]

and using the integer that controls the rotation value should be no different, if anything - more accurate, than using the relative rotation value

[scarlet root]

or in a more BP way:

RingX.RelativeRotation.Z -> Round -> ABS -> SetRingTargetX

[brave hatch]

ring targets are already being set. that's how they rotate.

I appreciate you're trying to help but it does kinda feel like you're not really reading what I'm saying.

[scarlet root]

No.. i am just thinking that all of this is kinda overcomplicated ^^"

[brave hatch]

lever activates (custom event first image) and dependant on it's number it activates the corresponding number

event tick fires bp function 'rotation tick' for designated ring

final image is rotation tick logic, grabs static mesh component and updates it's rotation by the integer values

[brave hatch]

how would you have done it then.

[scarlet root]

You have an event that you trigger by the lever..
Whenever this event fires, you want the rings to rotate to the next corresponding rotation..

So you want to create a Gimbal-Lock with Z-Oriented Ring rotation.

The rotations are in 60° increments and each lever switch pushes 60° on the ring rotation.. letting the ring rotate per switch on 0...60...120...180...-120...-60...0

correct?

As this:

only with Z-only

and if all 3 rings align, you want to fire a True branch

[brave hatch]

if all three rings are rotated correctly and align, yes.

then the entire mesh moves to the side.

think skyrim ruin door.

[scarlet root]

alright..
Scrap the tick then...

On Eventtrigger activation, you know what ring to rotate..

So you need 3 float variables
Ring1Target
Ring2Target
Ring3Target

They should be float, since they target the next rotation step.

So if you trigger the event, f.e. for Ring 1, you set:
Ring1Target = (Ring1Target + 60) -180

The -180 is because of Unreal's gimbal -180...+180

So you then know the target rotation..

Now.. add a Timeline.. and link the Play from Start right after you set Ring1Target.
Double-click to open it, to allow the adjustment of the curve keys.
Bets name the curve "alpha". Add a Key (right click line) at time 0.0 with value 0.0
And a second key at 1.0 with value 1.0
Close the Curve editor.
In your timeline Body (the update), you use a simple Float Interpolation
As Interpolation alpha, use the timeline alpha
As A-Input, use the Ring1.RelativeRotation.Z
As B-Input, use Ring1Target
From the Output of the Interpolation - MakeRotator > SetRelativeRotation of the Ring1

Add a new Event called "CheckupRingAlignments"

On Finished the Timeline: SetRelativeRotation of the Ring1 to be Ring1Target. Then all CheckupRingAlignments.

In CheckupRingAlignments check for:
(abs(Ring1Target) + abs(Ring2Target) + abs(Ring3Target)) / 3 ≈ 180
(maybe need to loop on specific positions so it rotates around)

The ≈is the NearlyEqual .. as Error Tolerance choose f.e. 0.1

And branch the output.

You can use 3 timelines, one for each ring. On such a construct, it's not that big of a problem.

A timeline is an internal timer object, already aligned with DeltaSeconds.
It runs through 1 time and drives your alpha curve automatically, so you simply interpolate from that.

---

This not only is an Event driven approach, getting rid of the nasty Tick Event (which you should use as sparingly as possible).. but also checks the ring rotation after rotating them completely.. making it error safe to not activate the branch before finishing rotation.

You also can change the speed of Rotation, by setting the second key of the timeline curve being later, or using the Timeline Reference variable and changing the play rate.

Good morning..

I will sleep then.

Work tomorrow.

[normal raft]

i am have a bit of trouble ratifying this small bit of logic.. (seems daft i know possible brain fog / reality filter issue)

the result I keep getting is that the ai pawn will climb from below min fly height .. and then once it reaches the height it starts fighting the other boolean which makes it fight the condition causing it to climb by 10 or so units then get pushed back down to min fly height

I want it to climb to 5k then continue to be able to climb to Max fly height then decend to min fly height

it may be able to climb simply because the distance to ground changed

[dark drum]

I'm not understanding. So you want it to go up until it reaches max and then at that point, go down until it reaches the min? But whats happening is it gets to the max, goes down a little and then go back up before reaching min?

[scarlet root]

What is the purpose / target of this Code?
An enemy flying up and down?
Actual climbing?

[normal raft]

yeah essentially that... but it still needs to climb if it got a new vector/or ground height changed and or somehow it got back bellow the min again,
i know i might of hurt my self by trying to do this in the the handling of it

[dark drum]

Oh so the min/max is the range it should stay above the terrain? So if its in the range, it doesn't need to change altitude?

[normal raft]

yeah

it doesnt need to change if its range (did try playing inRange(float))

[dark drum]

instead of returning a bool, i'd return a desired velocity (or float). The issue is you have 3 states but only using a bool which only has 2.

[scarlet root]

wouldn't it make sense to trace from the ship.WorldLocation downwards for (let's say) 10K units..
Check the distance between Hit Location and Ship.WorldLocation.
If > Max = Lower ship altitude (f.e. return -1)
If < Min = Raise Ship altitude (f.e. return +1)
Else = nothing (f.e. return 0)
?

so.. as patty states.. return just a value of 1 or -1 to change the altitude on the return

(or -speed / +speed of the change)

[dark drum]

So something like this. You can then use the int to modify the Z velocity.

Edit: You'll need to swap the 1 and -1 on the return values. 😅 I put them the wrong way round.

[normal raft]

💎

thanks guys i will look at this approach

i was playing to have it as enum state ultimately

but wanted to see it working raw first 😄

[dark drum]

You could probally just replace the 'Select Float' node with the output of the function. (have it return a float instead of an int)

[normal raft]

yep ngl that little bit of is kind of scarey

[dark drum]

Enums are just sequencely named ints so you could easily swap it in an enum if you wanted.

[normal raft]

ah but first the most important thing moar coffeee!

[normal raft]

yep that did it.... I went for the enum in the end.. and just 3 distinct logic paths.
now it works like that we could put the float auto select stuff back in easy as well

not that easy to see really but yepit decended from 15k

[normal raft]

nice needs a bit a tuning... but at least it no longer is having serious aviation accidents in my little city 😂

[lilac pasture]

hello everyone, how would one go about attaching a newly instanced object to a premade spot (component)? i tried using attach actor to component, but it straight up doesnt work lol. would appreciate some help greatly!

this is the setup if it helps

Hand Spot is the empty scene component attached to the player

[normal raft]

you need to give it a socket, or a provide a existing bone name

then snap to location

[lilac pasture]

is this possible if i dont have bones?

[normal raft]

yeah just open the mesh and add socket

[lilac pasture]

i'll look into it then, thank you for the help!

[dark drum]

It doesn't need a bone or socket. If one isn't found it'll just use the components origin.

[dark drum]

Two things jump out.

The class isn't loaded meaning the actor never actually gets spawned.
or
The cast fails so it never gets to the attach node.

Are you able to confirm the actor gets spawned? If so, does it get to the attach node?

[lilac pasture]

it does get spawned, the cast works as well

this is what the outliner looks like

during runtime*

but it doesnt follow

[dark drum]

Ok, what I would do then is change the rules to 'Snap to Target' and check to see if it's at the component. Sometimes you get get some strange offsets.

[lilac pasture]

i already tried to do this earlier and it didnt change anything then, but suddenly it works??? 😭 thank you very much, though!

[normal raft]

yeah i was morely thinking he wanted it to snap some where specific

[dark drum]

I tend to set the relative transform after its been attached. I believe Keep Relative is supposed to convert its world location into the relative location but I get mixed results.

[white parrot]

Did you check the location? (might be 0 in world)

Hello Blueprinters, Is there a way to switch Game Instance file, perhaps with a Editor Utility widget, in the editor, without opening the project settings?

[dark drum]

The game instance that is used is defined in the DefaultEngine.ini so I'd imagine you'd be able to modify that. Not sure how easy it would be from BP though.

[primal hare]

Hmm..I was hoping we'd have a console command for this?

[white parrot]

Console command for something that isn't bound to change throughout the entire game?
You could write one if you need it

[spark steppe]

kinda doubt it, the gameinstance exists once and is loaded during startup

[primal hare]

Yes, only want to change while in the editor before launching the game

[primal hare]

How would one go about it? Do you have one?

[storm aspen]

Hi, I need help with my ladder system in Unreal Engine (Blueprint).

Problem:
When I press E near the ladder, the character starts climbing automatically
and keeps moving up/down without pressing W or S.

What I want:

• E only to enter/exit ladder mode.
• W to go up, S to go down.
• No automatic movement when entering the ladder.

Here is my current Blueprint (screenshot attached).
What is the correct logic to handle this?

[white parrot]

Actually on second thought, it wouldn't work with a console command too since it requires relaunching the editor.
If it was possible it would require C++

[dark drum]

You'll most likely need C++ to handle it.

[fluid flint]

Hey, guys! I am new in Unreal Engine I am learning it 3-4 weeks and I am really disappointed because I see blueprints and I really cant understand them a lot. It's seems very hard for me to understand and create a logic for example that I want.

Is there anybody that is able to help me?

[dark drum]

What are you struggling to understand? Specific nodes or something else?

[fluid flint]

You know in college we have to translate a unity project logic to unreal engine with blueprints and I don't know where to start. I just started creating UI like the title menu with press any key to start text and I don't really know what to do exactly right now just got confused.

I have no experience with blueprints at all and it seems very difficult to me

[white parrot]

If you have coding experience, C++ might be easier.

[fluid flint]

Yes blueprints is the issue here cuz we have to translate strictly with blueprints

not a programming language

Maybe is there a course or something

[dark drum]

For me, I'd start by creating the same classes -> create functions (add desired inputs/outputs) -> Assemble logic.

A branch node for example is just an If statement. Where ever you see an if statement, add a branch and then connect the variable (bool) it uses. This could be from a function if the function returns a bool. Just like C++.

You have to remember, BP is just a node that encapsulates some C++ logic. (for the most part)

[last peak]

Blueprints are a programming language 😛

[white parrot]

Try writing some pseudo-code then, the logic is the same for C++ and blueprints, just the difficulty of playing the "guess the name of the node" game in blueprints

[last peak]

Its code with a picture ontop

I feel like blueprints are super intuitive for easy stuff

[dark drum]

or 'Remember the name of the node'. 😅 There's been a few times i know what the node is and what it does but not the name. lol.

[last peak]

You want to set the location of a actor ? ofc you would use set actor location ^^

[dark drum]

Do you have a short code snippet? We might be able to provide an example.

[normal raft]

@dark drum with the brain fog / reality filter thoroughly reset by a good dose of caffeine + reality check we have this

[frosty heron]

Tbh if you know how to program you dont really need to learn blueprint. You would know your way around it. Like whats the issue? Aint no different calling a function in cpp with drag and dropping node in blueprint.

[normal raft]

i was reading how you can make your own editor tool the other day

so you basically get a icon/menu slot

[frosty heron]

Theres plenty of way to extend the editor. But if blueprint exclusive then the only option and limitation is probably editor utility widget.

[ruby shard]

Guys so I have an arm that comes up with Two Bone IK is there a way to make it so the arm doesnt get affected by walking anims?

[frosty heron]

Filter by bone

[normal raft]

hrm interesting the whole issue of the logic fighting came back 😅 .. but yep i was hoping to avoid to do some thing like making the AI Input Locked out of of the altitude calculation

each state has to know its locked out for now

[crude marlin]

I think you miss the point, the point is that i want to create a flow that allows me to have my bluprint wok on any version.
Compiling the plugin is not a problem. its the reason.

Submodule the plugin to a new project for each Unreal Version. Great now i can use that to build the plugin on all thos eversions.
Ooups i saved a blueprint while testing in 5.7 now it wont work on 5.4 (This is the issue)

Solution: downgrade assets. if they got saved in a new version, and use the cicd to verify that they are not broken.

[normal raft]

with this as a reference its always happy patty, never seems to crash or any thing .. but i am never there to see it lol.. but some how i have still found it a few hours later at absurd fly height and refusing to descend then when i debug it i can see both the logic branch's triggers at the same time .. its kind of weird i must say ..

i was curious if the way the original poster did things .. is going to mean that the each time the vector comes inside the BTT function and calls its children functions that the target vector might need to be adjusted some how ? ... because the behaviour tree is just going to keep hammering until its satisfied as well right?

[dark drum]

Remove the sequence. With it the bottom ones will never call because the return node stops the function. The false pin on the first branch should connect to the other branch node so it can perform those checks.

[normal raft]

just for good measure i made the take off height slightly higher then max height so it can drop into the logic better 😄

maintaining 10K which is what its programmed for

now we something to tell it to stop doing that

you reach 10K ignore all other logic just keep decending to where god told you its ok to fly

yes in the ST/BT make it so it gets bored and the can override that function alltogether

[humble ravine]

Hello guys,

hah it cut it off but yeah can update it actor transforms

I want it so that when the correct widget is visible in the Widget Switcher and the confirm button is pressed, it gives the currency. But if the wrong widget is showing, pressing confirm does nothing. How can I do that?

let me know if you need it better explained

Swap your sequence pin connections around. The bottom one is being triggered first which would randomise the widget before doing the check.

[queen dagger]

im trying to get player names loaded onto a text box in the hud however im having issues loading names for anyone but the host

[ornate trail]

sounds like you might need to multicast the names from the server?

[faint pasture]

player array should be in sync

[faint pasture]

WHEN is this thing constructed?

[ornate trail]

why tho? cause it lives in the player state?

[queen dagger]

good question we do server travel load map, change controller to the game controller and in the event begin play on the contorller it calls a function to show hud

[faint pasture]

Player Array lives in GameState and while it's not literally replicated it is kept in sync

[hollow mural]

Hi I have a question regarding optimization...

I have 100 bp sound actors into the game, they're crickets 🔊 they only enable during the night 🌃 🌜 ....

My day and night cycle is in my level blueprint....

Is it too many calculations to use Get All actors of class?

Something like this...

Or should I only save into an actor array variable only those spheres that the player is currently overlapping? 💾

For example, crickets start singing at night, chickens stop signing at night, and they start clucking during the day 🔊

[ornate trail]

calculation wise it's fine but instead of looping you could just use an event dispatcher

[hollow mural]

You mean dispatch from the BP_Cricket audio actors, or from the bp_levelscriptactor ? ⚙️ 📨

[queen dagger]

is timing here important? as far as i know these names are saved in the main menu of my game. and are available in the game lobby, is switching between gamemodes what may be screwing it up

[ornate trail]

you would call it from when your day /night changes. Any actors subscribed to it would run the appropriate actions

if say your crickets and animals are of the same parent class you could call a dispatcher with a time variable. Then depending on the time passed they could do different things.

[faint pasture]

The player array is not persisting across a map change unless you're doing something fancy

[queen dagger]

hmmm

[queen dagger]

well do i need an array to call the pl;ayers name if i only want to show the name of the the one player

[normal raft]

maybe less calculations with actor tag?

[wispy mulch]

How can I minimize this effect where the camera spins around like crazy when an enemy is too close to me

[normal raft]

rotation velocity in character movement

if your cameras all directly tied to that stuff

usually its absurdly slow from i recall

but yeah just set that it will stop all that wild rotation

[faint pasture]

What owns this widget?

[fluid flint]

Hey, guys! I have a question. How to rotate my player character (capsule), when rotating the camera?

They both have to rotate at the same time and I was just wondering how I am supposed to do it.

[rustic rover]

Hey everyone!
First time writing here, I hope I'm not doing anything wrong... 😅
I'm a little lost about collision-related setups!
I have a prototype here nearly working well, where I select cubes, then click/touch a destination tile and the cube move there automatically.
The problem I'm facing is that I have this box collider around my trees, which I need for internal thinking, like for my pathfinding to be aware of those trees while doing the line traces, etc., but I'd like to be able to clock this red tile even if it's behind the tree's box collider... (for now I'm rotating the camera until the path is cleared!)
I'm kind of lost about if I have to play with the trace channel from my player controller (sending rays from camera) or if I need to tweak the properties of the tree's box collider, or both, and how and etc. Eheh!
If anyone have any comment to enlighten me, I'd be forever grateful + 1 day!

[normal raft]

the red tile is the mesh collision

the pruple is collision box/sphere/etc

[rustic rover]

Yes. I want my trace from my camera to be able to go through the purple one to be able to hit the red one.
But I still want for the purple one to be hit by other traces, like my pathfinding checks.
I think I haven't been able to explain clearly yet! 😅

[normal raft]

no i get you

i do the same with my space ship that is made up of multiple parts

not sure if a custom object channel or a trace channel will be best

[rustic rover]

Neither am I eheh!
I think I'll just stop for now and digest some collision-specific tutorials!
Even finding the solution here won't mean I'll understand it, so...

[normal raft]

like i alawys think of it like layers of a horrible onion

but yeah to walk through one layer

you need to consider the next

but yeah in reality the game engine does it for you when you do it right

[rustic rover]

Yes eheh I think (I'm sure) the problem lies here: Me not doing it right!

[dark drum]

Id say custom trace channels but hard to say without knowing more about how some of your other logic works.

[rustic rover]

I have those cubes.
When selected, I can first click anywhere, and a path appears from the cube to where I clicked (or the closest possible tile if unable to reach)
The pathfinding algorithm check with "line trace by channel" node to find the path, and when checking, it looks for anything around each tile, include atm my trees. And it's working fine.
If I second click the same tile, the cube moves, if I click another one, the path is updated.
I'm also using trace by channel for clicking (but with cursor position), and I'd like for this one to ignore those trees. Or better, ignore everything that is not a cube or a "walkable" tile, or to just consider them...

[normal raft]

ok so lets say your made a object channel called purple

then you block purple in ever other trace/channel

its easy to debug 🙂

block or ignore those custom channels/traces either way

if you want something else then do it inside

i think the limit is 84 or something

not to bad

[rustic rover]

Thanks I'll have a look at that!

[hollow mural]

why would be calculations less with a tag?

its already getting only the actors of BP Crickets Class

[normal raft]

yeah fair enough

not sure what the true saving would be there anyway

i know using has tag does save allot of time from the out set checking if things are valid in some outsets

[queen dagger]

what do you mean own?

[faint pasture]

Who creates it and holds a ref to it?

[queen dagger]

the palyer controller

[faint pasture]

playercontroller knows about its corrosponding playerstate

have the playercontroller feed a ref to that playerstate or even that name to the widget

[normal raft]

also good luck casting to every thing with out a tag

froma generic actor and such

[dark drum]

Id go down the route of using an event dispatcher. Personally, I'd have a global clock manager that just managers time for the game. On the transitions from day to night, have it call the event dispatcher.

If you make it as an actor component it can be placed on the game state and be easily accessed by actors. You'd get the component from the game state and bind to the event.

[hollow mural]

can I just do event dispatcher withotu doing the global clock manager thing?

[dark drum]

Not from the level BP.

[hollow mural]

not like this?

[dark drum]

No because the other actors would need to be able to get the level script actor (level BP) and cast to it which isn't possible in BP.

[dark drum]

Yea you can get it but you can't cast to the specific level BP. (I couldn't find a way the last time I looked)

[maiden wadi]

Not a specific level no. You have to have some foresight with that and put a new LevelScriptActor in your levels that has the stuff you want to get access, and then you can set it or override it in the level BP.

It's fucky. Don't advise. But possible! 😄

[dark drum]

You can technically add an actor component to the Level BP and use the get component by class on the level script actor to get it.

[maiden wadi]

Yeah, that as well if you wanted to go compositional, for sure.

[dark drum]

I don't think you can cast to your own child of the level script actor though which is a shame.

[maiden wadi]

Cast no. But the autocast of the GetActorOfClass will still return it at that pointer level.

[dark drum]

Interesting, I never thought of that. 🤔

[cinder helm]

do you guys know why my Get doesn't have the same inputs and outputs as this unreal tutorial?

[maiden wadi]

Right click it and convert to validated get.

[cinder helm]

whats the diff?

and thank you

[maiden wadi]

One serves as an IsValid node and a getter. The other one is just a getter.

[dusty spruce]

love a recursive function in blueprints

[viral cradle]

General bp question:

When I drag a pin out how do I get a list of only the "relavant api"?

For example here I have a data table

I would like to see all blueprint exposed functions which are members of that data table, not the entire blueprint library.

Essentially I just want the functions that are in the h file

UPROPERTIES would be nice too

[next hollow]

From my beginner-medium experience.
While that is a great want.
Its a bit impossible because the functions don't have to be defined in the same type/ var file.
Say DT's for instance.
None of there BP functions are in the DT file I believe.

[sand shore]

Well it’s kinda that “context sensitive” checkmark. Theoretically you should only find things in that current list which might be able to operate on that context

[viral cradle]

yeah I just want to be able to restrict the context what what is really relevant.

Like remove the data table part entirely

I have an object

It has UFUNCTIONS and UPROPERTIES

I just want to see those.

Like I get with intellisense with rider in this screenshot

The thing is this is actually probably the single biggest point of friction for me with BPs
It sounds like its not supported though.

Like I want to see the library sometimes, but most of the time I just want to call a function on the thing I'm using

[viral cradle]

I get it, but context sensitive includes tons of things which are external libraries which include hundreds or even thousands of functions, and buried in that pile are the actual functions my object owns.

[sand shore]

The next closest thing is https://dev.epicgames.com/documentation/en-us/unreal-engine/blueprint-namespaces-in-unreal-engine

But I doubt all the existing code has logical namespaces

It’s really more for your own BPs

[viral cradle]

Its not a solution, but this is useful, thank you for taking to time to humor me, I appreciate it.

[dark drum]

Putting functions and vars into categories helps. (And sub cats) You can just search for the cat then.

It looks like some changes weren't pushed and never got merged.

[raw latch]

how to fix it?

[dark drum]

Is it just yourself that's been working on the project?

[raw latch]

2 people.

the art brunch got merged with coding one after this it happening

[dark drum]

So you could see if anyone hasn't yet pulled the main branch that has the missing files. They can push and merge with main.

If not, you'll have to try getting the missing files from the previous branches.

[raw latch]

I recently pulled it . after that this happens

[normal raft]

you might want to .. git diff <local branch> <remote>/<remote branch>

[cerulean mango]

Hey everyone,
I’m working on a multiplayer game using Steam and ServerTravel between my Lobby map and my main Game map
What is currently the best way to implement a proper loading screen in this setup?
I’d like a loading screen to appear between the lobby (where players connect) and the game map
I’m using ServerTravel, not OpenLevel
I'm using both cpp and blueprint !
Any advice ? 🙂

[maiden wadi]

Pull CommonLoadingScreen out of Lyra.

[cerulean mango]

Thanks ! Is that hard to integrate ?

[white parrot]

It's just a few lines of code in 2-3 files

[civic quartz]

Does anyone have an idea what could cause the Blueprint Editor to not allow any operations on nodes (add comments, copy/paste/delete)? It's happening with shortcuts, but also via context menu (see screenshot, options grayed out). Closing and reopening the BP helps, sometimes also just starting a PIE session. Compile and save almost never helps. And this state seems to be persistent when not reopening or at least takes minutes to resolve. This is happening so often (basically every time working on blueprints), that it really is very annoying. Being on 5.5.4.

[maiden wadi]

Not sure if you've already looked. But you literally just need to grab the plugin and put it in your own project. Then in the Project Settings under CommonLoadingScreen, you pick a widget class. After that most of the map travel cases are taken care of for you. And you can also make uhh.. forget the name. LoadingScreenTasks.. or something like that, which keep it up when you want. Like if you load into a map and need to do a bunch of setup work before dropping the loading screen.

[maiden wadi]

This has been a bug in the latest few versions. It used to only happen on purpose when you had a PIE session open. But rarely some BPs will get stuck like this even with PIE closed and you can't do much besides a reopen/reload.

[civic quartz]

Hi, thanks for the reply. Well, it is not rarely in my case, I almost can be sure that I run into it during a blueprint edit session. Means, every 5 minutes, being stuck. But, anyway - must live with that.

[meager igloo]

Is there a way to paint directly on a texture of a skeletal mesh in runtime?
Or are there any good plugins for that?

[normal raft]

not sure but collision of the character mesh isn't blocking the axe ?

[normal raft]

So i found out why my altitude system was having so many dramas that made no logical sense what so ever

hitting both surfaces

not sure if that can be prevented

[normal raft]

yeah that is problematic for sure because i cant afford to ignore planetsurface when i am on a worldstatic structure as they are also classed as a surface

[normal raft]

this is the core logic if any ones got any ideas/advise

[dapper acorn]

quick question
I have created a new pawn to be my default player character, and then made a new game mode class so that I can make it the default pawn

to make my input actions work, in OnBeginPlay I had to add the EnableInput node

is this standard practice? When I look online it keeps suggesting that EnableInput is for enabling input for other actors. Does this imply that for the default player character I should be using something else?

[normal raft]

might be the auto poseses pawn stuff

[dapper acorn]

I just want to make sure I'm not doing something wild

it works fine but that's also because I don't know any better! 😄

[normal raft]

yeah if you look at your pawn.. you should see the settings that it will get possessed by either being spawned or placed in the level

then you get the event onPosessed

[dapper acorn]

does any of that affect default input? What I'm trying to say is that is there a way to designate a pawn as the "player character" that has input enabled by default, without needing to set all the input up within OnBeginPlay?

doesn't matter if there isn't a way, just want to make sure I'm not missing something obvious

[normal raft]

well yeah because you can assign the pawn its own input mapping

if you didnt it would just use what the last mapping was for input

this is how i possese the spaceship for example with a different input mapping

[dapper acorn]

You mean the input mapping contexts?
Am I right then in thinking that you have to add a mapping context in OnBeginPlay? There isn't a setting somewhere that states, "default pawn input mapping" that handles things at compile time or something

[normal raft]

not neccesarly you can have a interface or other event like onPosesess to take control of the mapping and enable/disable the controller input

[dapper acorn]

that's all good
it's as I thought it was then
thanks for the help!

[normal raft]

yep basically your not doing any thing wrong 😄

https://www.youtube.com/watch?v=jfctzoxrD6c

just a little walk around of whats trying to go on

[dense hound]

Hello can somebody please help me with Unreal physics, im crying out here. Basically i have items which have Physics enabled, i interact to pick them up, turn of collisions and physics and then attach them to a scene component in my Player. But for some reason the mesh wont move and is basically stuck. Only the Pivot point attaches to my scene component. If i check the items in level, physics and collisions are turned of after i picked them up. My inventory array works correct as well .

[ornate trail]

attaching won't set the location for you if you leave it to keep world. If that's the way you need it set the location too

[dense hound]

I did snap to target in the node

[ornate trail]

oh ha. I'm blind, so it's not snapping?

[dense hound]

no it only works if i completley disable physics for my actors, but as soon as i turn physics on, everything is stuck.

[ornate trail]

well your player normally doesn't need to simulate or have physics collision enabled. normally idk what this game is. but just doing what you have should work...

might be the attach, try just attaching the component to the player not the entire actor

[dense hound]

well im just trying to set up basic mechanics like picking up items and dropping them. If i have no physics you cant throw around the items and i have to teleport them on the ground.

[ornate trail]

just enable collision and simulate when you drop it, that's pretty standard

[dense hound]

so just keep simulation turned off from beginning, got it

[ornate trail]

or disable it when you pick stuff up. either way

[dense hound]

yes thats what i did, and it didnt work at all

[ornate trail]

it might be failing. attach return a bool, you can log it to see if it worked. try just attaching the component to the player not the entire actor

[dense hound]

the funny thing is it returns true, like always

[ornate trail]

what is the actor setup?

[dense hound]

just a scene comp as root and a static mesh

[ornate trail]

yeah that should work. but in your graph your looping through your inventory and attaching each item?

also why are you trying to disable physics on the class and not the actor? that wont work

[dense hound]

yes inventory works fine, i turned of simulate physics in my actor and it works much better now, item just attaches weirdly after first drop, i think ue5 has a problem when i turn on simualte physics from the details panel

[dense hound]

no i got the static mesh from that class, and disabled physics for the mesh

[ornate trail]

what I mean is get the actual mesh, what ever it is called in your item

yeah thats very strange, get the mesh directly

your item should have a base class where the mesh always has the same name, you cast to 'my item class' and once cast you can get that mesh directly

[dense hound]

you can choose "static mesh" in get component by class, then it just gehts the static mesh for the class the actor has, which im picking up, but yes casting works as well

[ornate trail]

yeah you can but not really advised, if you ever have 2 Static meshes its an issue

I would say take it out of the loop, setup a debug key 1 and try attaching that way first. simplify the debugging

press button -> attach something

[dense hound]

okay now it works, because of physics, the item mesh and the pivot had an offset, which left the item attached on the ground after i dropped and picked it up again. Issue was turning on simualte physics in details.

[ornate trail]

if you need offsets use a socket in your mesh

[dense hound]

yes my character kinda doesnt have a character mesh, i just addet a scene component which i attached the item to, didnt want to bother with animating the body

but thank you for your help, was going crazy

[ornate trail]

no problem, even just a cube with a socket will work

keep things simple and dont loop at first

[dense hound]

oh didnt know you could add sockets to meshes, thought i need bones and stuff

[ornate trail]

static meshes have this tab

[dense hound]

okay ill check it out

[torpid acorn]

hey i need some help how would i make a wall splat happen for my charater fyling into a wall i an a beginner in ue5 and im lost on how to do it?

[deep wyvern]

hello! im currently having an issue with a Begin Overlap function

I want to enable a postprocess volume whenever the camera's box collision enters the volume's bounds (in this case, water). The camera box collision is set to overlap all channels, as well as Generate Overlap Events.

So in this case. when i jump into water, once the camera enters the bounds, the screen tints blue as it should

however, ive found that the overlap event only occurs once the player character takes any kind of movement input, or moves at all, like the camera box can be overlapping the postprocess volume, but the change only occurs once i begin to walk or do an action. the same goes for the End Overlap event.

so in this case in the video below, im standing completely still on the ledge with water below, and when i move the camera within the water's bounds, the change doesnt take place until my player character takes input.

so i know the overlap event is detecting my camera's box collision, but i just dont understand why the event only fires once i start moving.

ive also print string debugged the camera box collision's world location to verify it is in fact moving with the camera

[torpid acorn]

so far this what i've come up with

[lofty rapids]

what is this supposed to do ?

[torpid acorn]

a wall splat

when your character hits a a wall when either filying/ swinging to long

[maiden wadi]

By wall splat, you mean like a visual of where you hit the wall?

[torpid acorn]

Yes

[maiden wadi]

I'd probably start with a decal. Simple enough to place using the hit location and normal

[torpid acorn]

Im very new to this so ididn't know

[torpid acorn]

actually can you all help me improve it more? this is the current iteration of the code of the wall splat

the only probublem is that it will trigger when on top of buildings since im going off height abovove 0.5

[queen dagger]

Thats my original idea, but i feel like im missing something for identifying which player state to use

[frosty heron]

So you have a bunch of player characters and you want to display their name which lived in player state?

[queen dagger]

Yes

[frosty heron]

In that case,

PlayerCharacter-> getPlayerState

[queen dagger]

I’ll try that now

[frosty heron]

Dont use get player character with index that just gonna give you a random one at best.

You need to pass the character to the widget.

E.g createWidget->InitData (pass the character)

[queen dagger]

?

why character? i assume that the player state is tied to the controller

[frosty heron]

Refer to my msg above

[frosty heron]

Client only know their own controller.

You cant access anyone else controller as client.

[queen dagger]

correct

[frosty heron]

Exactly...

[queen dagger]

thats all you should need right?

[frosty heron]

So you understand why we shouldnt get the controller then?

Read the pinned material in #multiplayer

[queen dagger]

but i dont need everyones name, i just need the name of the character that is being controlled, i would assume i can pull from my player state bp from the controller unless that cant happen

[frosty heron]

Being controlled by whom?

Context matter here

Maybe you can run this over from the start. Since game start.

How the name and stored and how you want to display them.

I was under the impression thst you want to see everyones name.

[queen dagger]

sorry no each player will only see their own name

[frosty heron]

As in player 1 character showibg player 1 name, player 2 charscter showing player 2 name and so on.

#blueprint message

[queen dagger]

yes

[frosty heron]

I gave you the solution and reason why you cant involve controller for this.

If you cant do it then read the pinned material 12 times, is the most common advice.

SpawnWidget->initData(pass the character-> get character plsyer state -> get name

---

Widget bind to the player state delegate when name is updated.
Player state OnRep Name -> broadcast

Widget run a function -> set text (name)

If it isnt clear i will reiterate.

Client only knows their own controller and no one else.

So when a client run the code to get the controller->getplayerstate on a controller that is not their own, it will be null and your code breaks.

[queen dagger]

that part makes sense

[frosty heron]

Player state is replicated, meaning every client have copies.

Player state is also reachable from the character.

So dont overcomplicate this.

When you create the widget, pass the character or the player state of the character.

Then simply pull the name from it.

I would suggest doing with delegate and on rep above though because you will need to address race condition if your widget is created before the player state is valid.

[queen dagger]

i know it should be simple and what you say does make sense, im just probs making it too tricky

[faint pasture]

the playercontroller knows about the playerstate for itself

[queen dagger]

then it should be as simple as get player controller get my bp player state that i made and get the name right?

[frosty heron]

No read what adriel is saying.

It only knows the player state for it self. But the client doesnt know anyone else controller. No copies exist in their machine.

So you can get the player state from the controller on client ONLY for the controller it owns.

It cannot reach other machine controller as copies dont exist in their machine.

In other word player 2 doesnt know player 1, player 3, plwyer 4 controller. Thus it cannot get the player state through the controller thus the client cant get the name routed from the controller.

Need help with pause menu code

Is there an easy way to globally pause everything or do I need to do some legwork on individual blueprints to make sure no extra processes are running?

For instance, I've noticed a timer I've set in a widget is still counting down when the game is paused, and that makes me worry other stuff is also still running when I call "set game paused"

[last peak]

Eh

Maybe set global time dilation

[eager thicket]

does "set global time dilation" impact time based processes outside of event tick?

[maiden wadi]

The other issue is that you shouldn't be doing a countdown timer in a widget.

Countdown timer should be on whatever it's meant to be on. The widget should be able to pull the timer or start/end time of the timer, and display itself accordingly.

Hello does anyone know the solution to this while using post process outline material and custom stencil etc. The stencil here is 4 which should be white but some parts are green when look from an angle like this, green is another material but uses a different stencil value

[floral stump]

This doesn't applied in this context, its blueprint related not unreal, unreal is pure C++, bp was long post depricated and will be replaced with unreal new scripting language

[spark steppe]

the sky is blue, water is wet, missty talks BS

can you give a link about the deprecation plans?

or deprecation notice, since you said it's post deprecated since long ago

[hollow mural]

Hi I have a problem, im trying to play intermittent sounds on my actors, I dont want to use randomized timers on all my actors for sounds because that will be too expensive and it will have toooo many times all over the place if at one moment I have 50-100 actors all craeting those draw calls at the same time...

I have an audio component inside of all my actors

they're growling sounds mostly and other random sounds...

they are NPC AIs

is there a way to make this without having too many timers doing all these calls?

https://giphy.com/gifs/cat-loading-load-pVXyJy2k7WO1n49bGg

[frosty heron]

Timers, audio and draw calls?

[hollow mural]

yes isn't that creating too many "calls"?

[frosty heron]

Draw calls refer to rendering

[hollow mural]

oh I see

[frosty heron]

Have you profile and see if its a problem?

[hollow mural]

isn't there a similar problem similar to that?

[frosty heron]

Sounds like peanut to me.

You maybe trying to solve non existing problem

[crimson briar]

Make a manager and on spawn register enemies for audio privileges. And limit it to 10-20 at a time. You probably don't want 100 enemies making individual noises anyway because it will be painful to listen to.

[hollow mural]

they will not be all in one place, its an open world game.

4k x 4k landscape

my simple idea is to make a sphere collision over them and only have them work on these sounds when i overlap these spheres

[crimson briar]

Then it shouldn't matter. If you run into some performance issue with them you can pause the logic when the actor is too far away

[hollow mural]

I as in the player character

[crimson briar]

There is probably a system for that related to relevancy and/or LODs, but I don't know specifics, never did anything like that

[frosty heron]

For single player game with a single controlled character you can just care about the npcs that is around the character.

[solar needle]

urgent. i enable pawn sensing it doesnt show green lines

any help ? please :((

[austere orchid]

hey, can anyone help with this?
it appears as a little black box with squished widget, seeminly no matter what math i do

this is for a spectator screen

[hollow mural]

Hi I have a question.... im possessing another character in my game, and from that point, im not able to press inputs like left mouse button... But I can use inputs like jump, arrows, etc. I can use these things, I can rotate the camera etc,

I can not press left mouse button

[shut blaze]

well I mean if the inputs work
then, did you code for that character to do something when you press LMB?

[hollow mural]

my old character? yes, but im switching to a new character

I change and possess a different one what has no logic for what happens when you press LMB

[shut blaze]

if you have no logic when you press something, then you have no logic to run
The event still runs, but it has no code to run

[hollow mural]

no the run works, same for the jump

everything else works properly

[shut blaze]

but what doesn't work?

[hollow mural]

left mouse button event

[shut blaze]

show code?

you can try deleting and creating it again

[paper gate]

Got probably a dumb question, is there anyway to toggle this setting via code? Im creating a level design tool and I dont always want the 3D handles visable

[shut blaze]

1. try printing a string, if it works then it's probably a problem with your code
2. try removing and re-adding the node back
3. check your mouse

well, does it work?

[hollow mural]

I did use a break point and print string, none of them worked. I used Input Action as well as simple Left Mouse Button even. Also did the refresh thing you said. Nope

[hollow mural]

The input event is not executing at all

Input is being consumed by another Blueprint, either Old character, Player Controller, UI widget or Another possessed pawn 🖱️

[eager thicket]

where is a good place to handle pausing/unpausing the game?

I feel like it should be the Game Instance, but something tells me that isn't the right use. Can anyone confirm the absolute best practise for this?

[solar needle]

help ?

[ornate trail]

I usually put it where ever the input actions are, either player controller or player character

[maiden wadi]

I tend to find that the best place for the "state of the game", which paused or speed settings are, should go on the GameState.

In Atre we have a component on our GameState that handles our pause and speed settings. Little contained GameSpeedSettingManager thing.

[pine carbon]

When should you pass a Blueprint parameter by reference?

[maiden wadi]

A "Blueprint parameter"? Not specifically sure what you mean with this.

[pine carbon]

When should you tick that box.

[maiden wadi]

That's odd. Passing a pointer to a delegate by ref doesn't make sense.

In general you pass things by ref for two reasons. Performance, and because you want to alter them. But that being a pointer, performance is pointless there. And I'm 95% sure that will be passed as a const ref, so it can't be altered.

[pine carbon]

That's what I figured.

I wonder why it exists.

[fathom flint]

I need help.I'm creating a player slot widget using a player array with for each loop. There is a ready and not ready checkbox in UI. Inside the function, I get the character class variable (replicated) after BP_playercontroller cast to, and then I compare it with the `branch = empty character class. But I have a problem When player A selects a character, it shows as player B has also selected one. How can I fix this?

The same thing happens with character textures in 2D veriable :(

[maiden wadi]

For a start, you need to not have anything to do with the PlayerController here.

PlayerController exists on the owning machine and the server. If you have three players and one of them is host for example. You have nine characters. Three characters on each of the three machines. You only have five player controllers. Three on the server and one on each non host client.

Which means each OTHER client, will not have access to the other client's PlayerController.

Your PlayerArray should be an array of PlayerStates. Which you can also pull directly off of the GameState already. Each PlayerState can get their associated Pawn(Character). But really you should move this ready state to the PlayerState. Because it's the state of the player.

[frosty heron]

Is playerArray a bunch of player states?

Have the bReady bool in the player state.

[maiden wadi]

We have a whole LobbyState component on our PlayerState. Houses the things a player can pick in the lobby as well as their ready state since that is lobby related. Nice little contained thing to house all of the state for the lobby related to a player, and makes it easier to pull said data per player for gameplay initialization.

[eager thicket]

thanks

[fathom flint]

Chatgbt told me same thing. I tried it but got the same result. I think I made a mistake in RPC. Thanks for the information.

[true valve]

Since you can't use soft ref on datatable how do you load them on demand

[maiden wadi]

What do you mean by can't use soft ref on datatable?

[true valve]

datatable variable can't be soft ref right

i don't see any option . not like when i pick objects

[frosty heron]

You can but i dont know what you mean with when you pick object. Show us a visual of your attempt.

[frosty heron]

Always show code. Make it easier for people to help.

[queen dagger]

so each controller has a save game bp that i created, each just needs to get the name from its save game to show. should this not be as simple as get the player contoller get the save game profile and get the name from there

[maiden wadi]

#blueprint message

[queen dagger]

hmmm

so this will get the player array right

i just now need to identify which name to pull corrrect?

or more accurtetly which player state to gather the name from

[frosty heron]

Yeah and how r you going to associate it? We dont even know what sort of widget is this.

Is this like a name tag widget where the name appears pn top of character or is it like a list of players in the main hud widget.

Many codes r missing as well. At this point we dont even know if you already have the client pass the info from their save file to the server.

Where server replicate the changes.

[faint pasture]

Back up, what are you trying to do here? You got a widget, it's meant to show what?

[queen dagger]

right now it needs only to show the player name of that one player

[faint pasture]

What actor is creating this widget?

You mean "show the name of the LOCAL player" right?

On my screen it'd say Adriel, on yours it'd say vdmce

[queen dagger]

yes

[queen dagger]

yes, this hud is being created by a function on the player controller

[frosty heron]

Just break the ice, is it widget component hovering over characters head?

[faint pasture]

So why not this

playercontroller knows its corrosponding playerstate

[frosty heron]

He stated he wants to see other people name too

Like yesterday

In which case he cant involve controller.

[faint pasture]

Yeah just get player array in that case.

On my computer, the playerstate which is mine is the one where it is my local playercontroller.playerstate
Everyone's playerstate is in the Players array

[frosty heron]

He is struggling with associating the player array. He get the index and got stuck.

What he should have done is get the player state from the pawn. Which ive told like multiple times but no attempt on that part.

[hollow mural]

Hi, I have a problem... Im riding an animal... but the way Im doing it is because I dont currently have a proper animation, I just wanna add the character on top of this animal, like say horse 🐎 and make it invisible, and the only thing you will see is pretty much the animal you're riding. 🏇 ⚙️

This is how im doing the attachment to attach my actor on an arrow point that exists on top of this pig. 🐗 ⚙️

It doesn't work the first time

[faint pasture]

do you want to possess the mount when riding it?

[hollow mural]

But if I mount + unmount again, it will work ✅♻️

[hollow mural]

yes I am already doing that

But I dont understand why the first time the player charcater goes to chill at the corner xyz: 0,0,0 of the map...

[queen dagger]

Does not seem to be an option

[frosty heron]

#blueprint message

Implies controller class not your widget blueprint.

Also self refer to the instance of the object thats firing the code. You get that by right clicking on empty space and type self.

You need to make this clear though. If you want to see other player name. Stop involving controller, its futile.

[queen dagger]

i do not need to see other players names it just has to be the name of the player that is playing.

[frosty heron]

Then you just pull straight from your save game

But essentially you are saying that a player does not need to know anyone else name.

[queen dagger]

no

[frosty heron]

Is that really what it is?

[queen dagger]

it does not

[frosty heron]

Then do it proper way.

Have name stored in player state

Where its replicated and everyone have access to.

[queen dagger]

i have a struct that has that

[frosty heron]

Dont route from the controller but from the pawn.

@queen dagger i will run this with you on my phone for the next 15 mins if you actually answer the questions.

[queen dagger]

i am answering

[frosty heron]

How r u displaying this? Is the widget hover over the character head kind of name tag?

Or is it just a list of players at the corner of the main hud?

[queen dagger]

the text block is the player name

[frosty heron]

This doesnt say much. So you want a list of players at the bottom left?

If there are 3 players you will have like
player 1
Player 2
Player 3
Name on a stack?

[queen dagger]

i do not need to see other players names it just has to be the name of the player that is playing.

[frosty heron]

Loop through the player array -> is locally controlled -> cast to your player state -> get name -> set text -> break.

[queen dagger]

am i in the ball park

[frosty heron]

Yeah thats not correct

Loop through the player array

[queen dagger]

for each loop

[frosty heron]

Yes

Then check the element if its locally controlled

If thats not a function in the playrr state then you need to go

For each player state ->get controlled pawn -> is locally controlled.

This will filter the player state that belong to the local player.

[queen dagger]

closer?

[frosty heron]

Not instigator, get the controlled pawn

Actually that will assume each player already possess a pawn.

You can do this actually, get the controller from the player state.

If its valid check if its locally controlled.

If its invalid do nothing.

[faint pasture]

Because you're doing something totally off base from what you said

You said the PlayerController is creating this widget right?
OK in PlayerController:

Whenever -> create widget -> pass in self.playerstate

In widget:
read passed in playerstate -> pull out name

done

it's that simple

[queen dagger]

in here i would need to get the player state right

[frosty heron]

Yes, do you know how to make function with inputs?

You can pass the player state that way.

Well since the controller is already the owner.

You can also do, get owner cast to your controller -> get player state in your widget.

[queen dagger]

yes i do, should one of the inputs be the player state i created

so i keep running into the player state that is recommends is not the player state that i have created

[solar needle]

urgent. i enable pawn sensing it doesnt show green lines. unreal engine 4.27.2

[queen dagger]

so this one seems to be working, althopug i dont understand why completely

[frosty heron]

Because you need to address race condition when it comes to networking.

In otherword the data have to be readily available (e.g already replicated) before you create the widget.

If somehow you want to create the widget earlier then you will need to update the widget when the data is ready.

So if you create the widget and load your name save game file later. Then obvipusly the name isnt set yet.

You should never use delay to address race condition.

[hollow mural]

Hi, I fixed the previous problem. Now im trying to understand why after I unmount the animal, it will destroy it's wonder around logic, as well as it's begin play random intermittent sounds... Which is sad, it's no longer moving, it's like it got tired or smth from me riding it and then it becomes stuck in place. But I can still ride it again. It's weird tho.

After I un-mount the animal, im also restarting the Roam Around

This is my RoamAround

[crimson briar]

How do you unmount though? I don't see it on the screenshots. Unless the blue wire at the bottom of the first screenshot is a different pawn/character than the pig, but I can't know
