[celest coral]

hmmmm

[brazen pike]

You could do a switch on visibility? maybe? So that if it is visible it would make it hidden, and vice versa

Although it's getting a bit much at that point so there's gonna be a better way to hide it again

[opaque acorn]

@brazen pike

[brazen pike]

if you hover over the outputs you should be able to see what they are

although as I said earlier, I think you probably need to break the container first

[opaque acorn]

do you mean the tag array?

then print string to what it has to get if the tag has been added or not?

I feel like Gameplay tag broken O__O or bugged

nope Im stil not getting how to break the container first

any guide video on how to use gametag

[brazen pike]

yeah maybe try checking whats in the array

if the tag you're looking for is there, then the check code is broken. If it isn't there then the code that sets the tag isn't working

maybe connect the success print to it as well

[opaque acorn]

I think tag is not added in the static mesh actor

can you tell me the proper way to add gameplay tag to a actor?

btw is the "tag" and game play tags are same??

[brazen pike]

What are you using them for

Are you checking for a specific bp

[opaque acorn]

to get a general way to trigger change in cubemap only when that big box overlap with character

tag can give a way to not manually add trigger box

[reef marsh]

No they aren't. You can't add gameplay tags to any object unless it has an ASC but you can add regular tags.

[opaque acorn]

bottom line i must convert gameplay tag to normal "tag"

yes ty for confimation

[reef marsh]

There are nodes for both so that shouldn't be hard

[brazen pike]

That'll do it

[opaque acorn]

ok checking it

[brazen pike]

But it seems like you should be casting anyway, this doesn't seem like the right place to use tags

[opaque acorn]

gameplay tag>> write on tag>> success

[opaque acorn]

no its not limited to chracter

any shiny object eg. a glossy wall

when goes near some particular static mesh

will cause change in cubemap

[brave hatch]

for the 4.27 experimental features, specifically the EQS, how likely is it to be fleshed out completely and not ditched? and how long roughly? anybody got any idea

[tawdry surge]

Eqs was built on for the ue5 mass system

Afaik it's not going anywhere

[brave hatch]

good to know, just concerned about building anything on top of it and then having it break in future or not be supported

on that note, how badly do things break in updates from experimental to finalised?

[pastel geyser]

hy everyone ,
im having here a problem with my random ai spawn code :
glad if i cant get some help

[brave hatch]

might want to go to #gameplay-ai my dude

[pastel geyser]

didnt saw that thx

[tawdry surge]

If you're building in 4.27 it is what it is.
For serious projects and indies, you don't generally want to change engine versions once you're in main development.
So if it's working on your version then you'll be fine

[brave hatch]

currently in 4.26 but it's demo/concept stages. we'll likely build the finalised version in the latest engine release at the time.

but thanks for the info my guy

[glass stump]

What would be the best way to have a system whereby there are multiple levers in a map and when all of them are 'On' it opens a door? I've been looking into this for days and can't seem to figure out the best way to do this.
It feels like something that should be simple but it's not.

[remote meteor]

i think it can be entitled under a Puzzle System

where you need a certain Puzzle State to unlock the puzzle

[glass stump]

Ooh, I've never heard of this in UE4 before, but that sounds like it'd exactly be what I need! Thank you! :)

[remote meteor]

😅 well cus you need to make it yourself

its just an idea

[glass stump]

Well yeah but nothing I do seems to work. XD

I have a lever currently and a door. The lever, when pressed, turns a variable 'IsLeverOn?' to true. But then I apparently need to make a reference to the door.

Which I think I did, but then I couldn't figure out how to check the variable.

[remote meteor]

the way i did it was

i have a Puzzle Manager Component in game state

and i will add Puzzle Node Components to the related actors

to both the "leaver" and "door"

the "leaver" tells the Puzzle Node Component that the node state has changed

Puzzle Node tells Puzzle System "i have changed"

Puzzle System will check if any "desired" state has been achieved and notify the related Puzzle Nodes

then the Puzzle Node will tell the actor that "x puzzle has unlocked"

then the "door" with the receiving puzzle node will open

[glass stump]

Ahh, I was thinking about looking into doing it in the game state, that makes sense! Thank you, I will try to see if I can make this work. :)

[remote meteor]

you can use the "Contains" node on string to check for invalids

or you can use Regular Expression, although i think there isnt a blueprint Regex (i forgot)

a regular expression is better for that

https://www.unrealengine.com/marketplace/en-US/product/low-entry-extended-standard-library

this plugin has it and some other useful tools

try typing regex in the node search

🤔

cant exactly remember which one

https://regex101.com/

[glass stump]

Is there not a simple way of just telling a door BP to initiate the 'Open Door' event when a lever BP is 'On'. I don't know why this is so complicated.

I'd save time just by making a massive BP including the door and the lever.

[remote meteor]

you can have direct reference

door referencing the leavers and vice versa

but that you have to manually assign them in level designer i guess

[blissful grail]

It's not complicated in the slightest. It's extremely straightforward. You're just too new to see the solution. Doesn't mean it is complicated; just that you're inexperienced.

As IAsaka said, have the lever reference the door. So add a variable for the door, make it instance editable. Then in your level, select the lever, you'll see that variable can be set. Click on the eye dropper and then select the door that you want it tied too. Now, they are linked together.

From here, you just call OpenDoor on the variable in your lever actor when you interact with the lever.

[remote meteor]

well i wont deny the idea i proposed above (the puzzle system) is slightly more complicated 😅 i did that since i want to eliminate direct references

[high sapphire]

So I'm trying to check if the player has between 1 and 99 of a given item
How should I do that?

[blissful grail]

Tryin' to keep it simple for the time being.

[remote meteor]

is that a structure of gameplay tag and int?

probably a for loop and check for correct tag

then check for amount

[high sapphire]

Yes, it is. That's how I was recommended to set up the inventory system, back when I was getting help setting it up

Is there also a clean way to iterate through all possible items? For the weapons I was able to get away with just doing a branch for each possible weapon because the player only ever gets 4. But for other equipment types, I can see that getting pretty messy depending on how many armors/etc end up getting added

(This was what I did for the weapons)

[remote meteor]

for each loop the array to check for tags

[glass stump]

@remote meteor Ah thank you both I will try it. :) Indeed, eventually I will get used to it, I'm sure. XD

[remote meteor]

you can make a function to return all item with certain tags

[high sapphire]

... Wait, I'm stupid. The player can't have 99 armors equipped. The absolute maximum of multi-equipped things is accessories, and that's 2, not 99

[remote meteor]

gameplay tags allow you to search by the hierarchy

[glass stump]

Yes, it worked! Thank you. :)

[neat prairie]

i added a metahuman to my project... and this broke? anyone know how to fix this?

[gentle urchin]

So then you should have the weapon reference there. The return value of spawn actor of class (weapon bp)

[pulsar path]

you need to plug a reference to the weapon actor that is in the level in the object node

[faint pasture]

What do you think casting is?

[cobalt gulch]

I cant really explain

It's like doing it from something

[warm sand]

sorry my question was a bit unclear so I'll reformulate :

how could I swtich between a camera and a character.... I tried that but it doesn't work properly
https://gyazo.com/4392d63e18b4b02143e2836f2d9b4138

The problem is that the player moves as the camera would. The camera works normally. So the camera and the player have a different controller blueprint. How do I say that the character should have now the controller class of the character and not the one from the camera?

[pulsar path]

casting is just getting access to everything inside the actor you are casting to, like variables and functions

[tawdry surge]

Close

[faint pasture]

Casting is used to go from a more basic type to a more specific type.

If you have an Actor, and want to do Character things to it, you don't know if it's a Character until you cast to Character. Then you can make it Jump or whatever.

If you already have a Character reference, you can do Character and Pawn and Actor things to it. But if you want to know if it's your specific subclass of Character, you need to cast to MyCharacter.

If you have an Animal, and you want it to Bark, you need to cast it to Dog to see if it's a Dog, because only Dog can bark, not all animals.

If it was a Cat the cast would fail.

[glass stump]

@blissful grail @remote meteor Just wanted to say thanks fellas, finally worked it out with your help, after days of trying managed to get it completely working! XD THANK YOU! :D

[pulsar path]

this is also true, it doesnt seem like they are casting to a child class though, but rather a blueprint completely seperate from the character class they are casting from

How can I check if an actor is not a pawn? Do I need to cast to pawn and check the on Cast Failed?

I have a melee weapon attack with hit result, I would like to have some kind of hit react on walls that cancel my attack

you could also check the actor class from the collision event and check if its the same class as the wall class

i think either way would work fine?

[hot lotus]

I guess I could have a child wall class also yeah, thanks

my timer is not working

20 second timer

it just spams this

[faint pasture]

Well yeah, because that's exactly what you told it to do.

[trim matrix]

?

[faint pasture]

You told it to print frame time - TimeReduction

which will be like 0.15 - 20

or 0.34 in your case

What are you trying to do?

[trim matrix]

im pretty 20sec timer is connected to string

[faint pasture]

That's not the problem. The problem is you're doing this.

20SecTimer = DeltaSeconds - TimeReduction

TimeReduction is always 20

Deltaseconds is always some small number

It's doing exactly what you told it to do.

[trim matrix]

timereduction is = 20

[faint pasture]

Yes, so do the math. What's 0.33 - 20?

[trim matrix]

ive set to -1 each tick right?

ah shit

so what do i do

[faint pasture]

What are you trying to do, count down from 20?

Just do

20SecTimer = 20SecTimer - DeltaSeconds

it wont work

it goes to -800 in less than 3 seconds lol

[slender jolt]

Does anyone by chance know why my sphere trace by component isn't working? There is no sphere being traced on my component. I'm getting the correct component. The cast isn't failing. The trace works when I add a trace start/end.

[mellow folio]

So what isn’t working

[faint pasture]

Where is 0,0,0 in the world?

[slender jolt]

There is no sphere appearing. Sec I'll get screenshot of how it looks when I setup a start/end

[faint pasture]

This is a trace against a single component. What are you trying to do?

[slender jolt]

^ Is what I want to see. I this by setting the trace start & end via socket locations

[slender jolt]

Have my magic staff component deal damage via animation notify state

[faint pasture]

You are tracing against the staff, and tracing from 0,0,0 to 0,0,0

so its trying to hit the staff

and tracing a sphere around the world origin

I don't think that's quite what you're after

You probably want to do a sphere trace by channel at the socket location

instead of a sphere trace vs a component at the world origin

[slender jolt]

Ok. I did try that earlier but the vector of the sphere was all over the place. I'll try to refine it tho

I can do start trace from the weapon socket location

[fast blaze]

hello!
does anybody know howto calculate axis gamepad key gradual pressure?

[slender jolt]

and then manually adjust the end trace

[faint pasture]

Yeah just trace from socket location to socket location. You want your hitbox to be a sphere right?

[slender jolt]

Well the thing is there's no end socket location

sec I get screenshot

[faint pasture]

What shape do you want your hitbox to be

[slender jolt]

I wanted the shape to be the staff itself, but I'm not sure that's possible. Which is why I was trying to do the "Sphere trace component"

[faint pasture]

You can trace from tip to tip

from one end of the staff to the other

[slender jolt]

Ok. Tip to tip via a capsule?

[faint pasture]

No, a sphere trace

[slender jolt]

ah

[faint pasture]

a swept sphere is a capsule

a swept capsule is a IDK if it has a name

jus sweep a sphere from one end to the other

you want a multi sphere trace by channel most likely

unless you want all your hits being blocked by yourself

[slender jolt]

Ok I'll try. Thank you for the help

[minor wolf]

guys i think im actually losing my mind here. im trying to do a line trace in the direction im looking. GetActorRotation -> GetForwardVector doesnt account for my looking up or down which i guess makes sense? so do i need to use the camera's rotation instead?

[desert juniper]

yup

CameraComponent->GetForwardVector

[minor wolf]

do you happen to know if this is replicated to the server at all for multiplayer games?

[violet wagon]

you can also do GetActorEyesViewPoint

[desert juniper]

it is, but to an extent. there is slight inconsitencies with accuracy that I've noticed in the past.

What I've done in the past is to perform a line trace on the client (to get the 'real' hitpoint), and another one on the server, to verify they are 'close enough'

I may have gone about it the wrong way, but that's what I had to do at least

[faint pasture]

Get base aim rotation does the yaw I think. You need to mess around with all the rotations but some combo is equal to the control rotation.

[minor wolf]

ye thats what im doing now. i posted in #multiplayer about my current issue so im trying a bunch of stuff to fix it lmao

[desert juniper]

yeah, multiplayer is.... HARD lmao

I've started to convert over some of my actions to GameplayAbilities since they handle lag, replication, prediction, etc

but that's also a whole nother animal

[wise tide]

Can I freeze the game/lower the FPS when tabbed out with just blueprint or do I need to use C++?

[high ocean]

I've been struggling with this for awhile... I'm spawning meshes to the right of a spline. Sometimes, the spline has a certain roll rotation, it curls and I'd like the meshes to follow that instead of ignoring the roll of the spline:

How would I go about that? I just need to spawn those spheres along an imaginary line which respects the roll of the spline - any ideas? 😐

[flat coral]

Why can't i put an event dispatch call inside a macro, when I can put it in a function just fine?

Shit, I can even have a function that's literally just the dispatch call and put THAT in a macro. What's the point of this?

[tight schooner]

Might have to get transform or get rotation from a length along the spline. Hard to say without seeing your BP. In my imagination, from the rotator, you can Get Right Vector and multiply that by your desired offset distance, and add it to the spline location vector to make your sphere location

[high ocean]

@tight schoonerTried all that, rotation from spline doesn't seem to return roll 😐

[tight schooner]

Huh.

[high ocean]

besides, i'd have to lower the Z of the spheres according to the roll angle of the spline & there has to be some not so complicated way of calculating that

[tight schooner]

If the rotator was correct, Get Right Vector would point in the direction you want

[high ocean]

yep, but since the roll of the spline is always 0, it always points straight to the right 😦

@tight schooner

I'm just using dummy actors now with spheres to see them properly, the point is i'll need the location points to generate procedural mesh

So i'd only use rotations to get the vectors i need

[tight schooner]

ok here's where it gets dumb. I knew encountered this problem in my own project and I dug around a little.

[high ocean]

@tight schooner

oh? 🙂

[tight schooner]

you can Get Roll at [whatever] Along Spline

there are nodes

[high ocean]

ya, tried that - what dodo with it? 😛

[tight schooner]

and then [some sort of math goes here] = a useful roll value

lol

sorry I'm not being super helpful, but splines have their own concept of roll

that you have to convert to a proper rotator or w/e

[high ocean]

ya, read about it, stil didn't find an answer since 99.99% of topics are peeps tring to move stuff along a spline

aaaand, it's probably made at design-time, mine is procedural, so it isn't so easy to just poke around at it and test fast 😐

[tight schooner]

unfortunately I gotta run... scheduled to do something in a minute... but the "get roll at" nodes are the key https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Spline/GetRollatSplinePoint/

good luck lol

[high ocean]

[calm citrus]

Hey guys is there an easier way to make it to where I can only interact with things that the player is looking at? Or would I have to make a "cast to" for every object I want the player to interact with. (Ex. Door, Weapon, food)

[remote meteor]

An interface will help here

[brazen pike]

Could use an event dispatcher, an interface or have all interactables be a child class of a parent "interactable" which you cast to. But probably go with an interface

[calm citrus]

this is my interface that I have what would I put in here?

This is what it looks like in my BP_door

[desert juniper]

Simpler method is to just create an actor component, and place it on all items that the player can interact with

then you can just cast to interactable
this has the benefit over an interface that you can define standard interact actions (Begin Interact, End Interact, Interact, Begin Focus, End Focus) etc, on the component, and the logic is already done for all the objects that have this component

[proper wyvern]

Can I send a newly created widget to the background? It seems like new widgets (Create Widget + AddToViewport) always render on top of the rest of the UI, regardless of the ZOrder

[calm citrus]

hmm Imma try these methods thanks

[proper wyvern]

Or do I have to add it to my other widgets instead?

[brazen pike]

I don't see why you can't do this with an interface too? Just do the logic on your player and its the same

[pulsar path]

you cant put logic in a interface, you can put logic in a parent actor and have the children inherit it

then the children can change it if need be, or just leave it as defaults

[knotty violet]

Anyone know why I can't remove instanced foliage with an editor utility widget? It just comes back after I reload.

Tried destroying the actor, removing the instances by index, all of those things, always comes back

[brazen pike]

You'd rarely want logic in an interface anyway, with a lot of these cases each thing that implements them would have different uses (open door is of course going to be different to pickup weapon, for example). And, even though I've never done it that way, a component would probably be very similar in that the specific logic would still be defined in the individual BPs. So it ends up being basically the same, just now they have a component rather than an interface on them

[teal nexus]

I am having brainfart here..

So I have Z min and Z max (let's say -80 and 1600). I need to get Z in the middle, Z at 1/3 and Z at 2/3 between those values. How do I do that ?

[tight schooner]

Lerp node with alpha between 0 and 1

[desert juniper]

I'm not saying you can't do it with an interface. I'm just saying that another approach (and a more generally accepted one) is to do it with components

Separate out logic into components, rather then have one monolithic class (player class) that handles everything
it's the first principal of SOLID
Single Responsibility Principal

[thin panther]

personally i have seen the opposite with interaction done through interfaces being the more accepted approach

dont think i have ever heard it be component based

unless it's unity where it has to be by nature

[brazen pike]

okay man I be questioning my entire experience haha

[tight schooner]

I'm no industry professional but I've done it. If you need an interface with built in logic, components are the way to go. In BP communication, one BP simply checks if the other has a component, and if it does, calls a function on it or whatever.

[desert juniper]

I'm not saying it's the right or wrong way. but the way the engine is designed (as well as unity) is to separate out as much as you can into components.
it's the whole composition vs inheritance thing

[tight schooner]

... Then the component does stuff internally and has some event dispatchers.

[thorny hornet]

is there an easy way to convert an Array of Bytes into a String?
upd: nvm

[tawdry surge]

Unreal is built oop af..
Components make sense in some situations but inheritance/polymorphism is expected to do most of the heavy lifting.
For an interact event where the expectation is that you will be overriding the functionality in every class it's called on, inherited interface makes more sense than a component

[thin panther]

thats what i thought

an interact is gonna be different for everything

npcs interact may open dialogue or a shop, but tiems may go into an inventory

[faint pasture]

Component + dispatcher is what we use

[thin panther]

is there any inherent benefit?

[faint pasture]

Component is there so interaction can have a location and also so it's stateful

[tawdry surge]

Can you elaborate on that? I'm not following how that's unique to component+dispatcher vs interface/inheritance

[thin panther]

me too

[tight schooner]

I'll just say that in my use case, I needed an interface with built in logic/data that can be applied across different branches of the actor class family tree. It used to be a BPI, but I found myself copy-pasting the same override code but with different SFX/VFX at the end. So a component made more sense, with some event dispatchers so the host actor can apply its own cosmetic events.

[wise tide]

Can I freeze the game or lower the FPS when a player alt-tabs out of my game with just blueprint? I know you can with C++

[tight schooner]

Hate to say it but need C++. BP can't tell (last I checked) if the game is "focused"

[wise tide]

I see. Do I necessarily need to do this? My game feels pretty unoptimised and trying to do other tasks when tabbed out is slow and laggy.

Maybe I could avoid freezing when tabbed out by just optimising elsewhere

[thin panther]

the inevitable task of needing to learn c++

[tight schooner]

... You can find some code snippet. Personally I stole a function from "Rama's Victory Plugin" and stuffed it into my own C++ library.

[thin panther]

thief!

insert skyrim reference

[tawdry surge]

I feel like you could have just put the repeated code in the base class and simply overridden the vfx/sfx assets

[wise tide]

I see. I will probably check it out then.

As for optimisation is there a better channel for it? My game is pretty intensive but it is extremely barebones so it shouldn't be this bad. Not sure why it's like this

[golden frigate]

The event begin overlap for things does that apply if players collide with the actor?

For some reason it wasn’t triggering for me when my door which opens with rotation transform slaps the player

[tight schooner]

I already said it needs to cut across different class hierarchies. I mean sure, I could have some omega base class that everything in my game derives from, and put the sometimes used, sometimes not used code there, but...

[thin panther]

not a specific one so id chuck it in general

profile ur game, check size maps, and check shader complexity

you likely have some massive size maps hiding somewhere if you havent used soft ptrs

[tight schooner]

Yeah, look into profiling tools. It's a deep art

[golden frigate]

I’m basically trying to make it so when I open a door using rotation transforms, it will stop if u bump into the door as it opens

[thin panther]

event overlap does nto trigger for collisions

hence the existence of event hit

[golden frigate]

I’ll try a special even hit

[thin panther]

you will need to enable simulation generates hit events though

[golden frigate]

Just want to prevent players clipping the door

[thin panther]

just make it so all moving doors crash the game once bumped into :P

[golden frigate]

Ah yes makes sense

[desert juniper]

One thing I'd like to add is that with a component based system, there doesn't need to be a base class
Any actor can be interactable, as long as they implement the component.
It's more along the lines of the Composition vs Inheritance (and when to use one vs the other) paradigm

[golden frigate]

Also I implemented doors with keyholes interestingly idk if it’s the right way to do it XD

Basically I made a child of the door and added it to the door as another actor

[thin panther]

no way of knowing without an explaination

child actor component!?

[golden frigate]

Both the door and the child r “interractor” children

Which r targeted by line traces when u click

So the line trace will hit the keyhole bounding box and trigger an interaction event to set a flag

The door constantly looks for the flag of itself or the flag in its child actor

[desert juniper]

not saying one way is right or wrong, but generally, i see the trend to shift towards composition, and programing principals like SOLID

[golden frigate]

If it finds it it resets the “interacted with” flag

[thin panther]

could you just do that as normal components

like have ur keyhole part of the door

and a box collision on

[golden frigate]

I wanted to make it so my click detection will detect if u click the door or the key

And do diff things

The line trace from the FirstPersonBP returns actors it hit

So diff actors made it more flexible in my case where there will be things called “interactables”

A door is interactables and a key / handle is also

But so would be like a remote or a light switch etc

The difference being the child actor has its own functions that just do event tick if flag is true

Maybe there is a way to do an event when the flag is set to true tho idk

Not sure how to go from a parent class custom event to trigger a child class custom event

[icy dragon]

||did you mean Oblivion?||

[golden frigate]

Without saying a very specific name associated with a specific BP

[thin panther]

you trigger it on the parent

[golden frigate]

Ya

[thin panther]

this is why you use interfaces or whatever

[golden frigate]

So the line trace casts to BP interact which is a parent

[thin panther]

trigger the interaction interface on whatever is hit

if it has one

or that component

[golden frigate]

I like being able to have a blueprint for things that u can interact I feel like a seperate interface would get out of hand

[thin panther]

||potentially||

[golden frigate]

And I also don’t want to have to edit code somewhere whenever I add a new type of thing u can interact with

Which is y I went with the parent system

And I don’t want things u interact with to have an interface in game im just going with a screen overlay

Stylistic choice

[thin panther]

ye thats not what an interface is btw

an interface in code is different

[golden frigate]

Ah yeah is that in blueprints?

[thin panther]

yes you can implement them inn bps

[golden frigate]

I’ll see if that will work

[thin panther]

do some research into them

[golden frigate]

Might make things more efficient than checking flags every tick

[thin panther]

interaction is either done with an interface, or as i have recently learned, component with event dispatcher

[remote meteor]

Will*

[golden frigate]

I’ve used event dispatchers before

[thin panther]

yes it will make things more efficient

[tawdry surge]

@desert juniper it depends how base the functionality is.. components imo are good for encapsulating a particular set of functionality.
Making a component with an event dispatcher for a general interaction mechanic is too broad for a component and is literally the ideal situation for an interface.
Would make sense for a specific type of interaction like the widget interaction component.

[desert juniper]

yeah, can see how it depends on the use case.
as it stands, my InteractableComponents are a child of UWidgetComponent. This is helpful to me so that I can have player affordance built right into the interactable component (display a world space UI when OnFocus is called.
Lots of delegates are fired off that the actor can respond to events, or simply override the default component behavior

[golden frigate]

oh ya much better XD

[tawdry surge]

Yeah that's a particular type of interaction. You're popping up a 3d widget for the player based on the object selected. It's not opening doors, and turning on lights, and grabbing pick ups, and npc conversations, and 10 other random things

[golden frigate]

how would i do the door knob now tho?

ig i need the hit component

[tawdry surge]

You want to animate turning the knob?

[slender garnet]

Named Reroutes are awesome in Material graphs. Is there any similar ability for blueprints?

[golden frigate]

i will eventually animate the knob but for now i just want to know if they press knob vs anywhere else

doing it so if u press the knob w/ the right key it toggle lock state basically

[tawdry surge]

Then yeah get hit component

[desert juniper]

It's simply calling Interact.
It's up to the actor to impliment the event, and choose what to do. simple as that

[golden frigate]

ya works great

havent used interractors b4 so didnt know they were a thing

just went about however i thought it could be done XD

[desert juniper]

The component stays minimal, and the actor that is supposed to handle the interaction picks up the rest of the work

so ALL interactable actors have this single component. They can simply choose not to show the 2d widget, or any other affordance (like an outline)

[golden frigate]

how do u do an outline?

thats with interactors?

[desert juniper]

post process material

and a custom render pass

[golden frigate]

ok its a different thing then

this was my approach for getting a screen overlay when looking at something interactable

idk if its ideal since there is a cast

[desert juniper]

casts are fine. even on tick. just don't overdue it

[golden frigate]

Draw Interaction just uses a HUD to change the texture

same hud as the first person hud blueprint

but i could also add to that code a highlight call for the thing u look at

to say hit component

[desert juniper]

if you want I can share the code/material for highlighting the actor. I do it in cpp, but don't see why it can't work in BP

[tawdry surge]

If the component is carrying dead code for many of the actors then the only real bonus is you don't have to think ahead about your hierarchy

[desert juniper]

it's just a simple virtual function. can be overwritten like with any other base class

oops wrong reply

[tawdry surge]

@golden frigate unless your hud class is gonna change you can just get that on begin play and skip the cast on tick

[desert juniper]

This is a bonus that I really enjoy.
with how buggy UE can be about reparenting blueprints, this was a big plus for me.

[golden frigate]

i think UE5 changed how to do the highlight

cause blendables isnt a field for post process volumes

[desert juniper]

Turns out, super easy in BP

The outline is pretty ugly in UE5 though. UE5 doesn't like something in my material

[golden frigate]

set render custom depth only works if u have an outline highlight

i couldnt find the material or where to plug it in

[desert juniper]

in the post process volume

[thin panther]

you make the material and set it as a post process material

then add it to the blendables in ur ppv

[golden frigate]

is there a default material?

thats all that comes up for blendables

[thin panther]

yes

[desert juniper]

no you have to make it

[thin panther]

so you make the material and add it to that slot there

[brazen pike]

There are dozens of highlight materials you can find free online

[desert juniper]

I'll need to find one that works better with UE5 than the one I have now

looks like it got hit by all the jaggies

[golden frigate]

how would i turn the outline off when not looking at it 🤔

should i event tick turning it off or is there a better way

this will turn on the stencil outline of the thing i look at which is interractable

[icy dragon]

As in not in view, or directly in the center of the camera?

[golden frigate]

well not in the parameters defined here

it shows a highlight if the mesh is hit by a line trace

aka if u clicked it would interact

how should i go about turning the outline off

because when the line trace does not hit something i wont be able to reference that something

[icy dragon]

Just disable custom depth on it if line trace is missed?

[golden frigate]

how tho

this event tick is from the First person character

it wouldnt be able to disable the depth on the thing it didnt hit

:/ i guess i could do like an integer timer?

if collide set var to 2, on tick decrement var, if var is 0 turn off outline

i just dont know if its bad to event tick turn off outline + set depth

[brazen pike]

Set a reference to the actor you are looking at. Then the next time it fires have it check that the actor being looked at matches the actor being referenced. If it isn't the same, check if the reference is valid and turn off the highlight on the reference, then clear it. If it is the same, then do nothing.

[golden frigate]

thats a pretty good idea

basically before setting something to outline check if the last one is same

ideas to fix this? it works btw

[brazen pike]

Send a screenshot of the broken code?

[golden frigate]

i could maybe do a validate get?

[brazen pike]

Yeah check if it's valid first.

if you aren't looking at something it's going to be invalid

[golden frigate]

yeah the code i wrote there looks organized and clean but i think to avoid the error i need a diff order

more messy

[brazen pike]

also, do you need to set custom render depth true/false if you're using stencil? Tbf I haven't used that system in a while but from what I remember you can just set stencil 0 to be nothing but 1 as the highlight material. Then anything you want to be highlighted has render depth on by default and you don't need that extra node

[golden frigate]

i can probably just change the stencil depth

but idk if things with custom render depth have extra load

i would imagine that even if its values does nothing it needs to pass through the ppv

weird i still get the error using this:

[brazen pike]

I'd guess so. I wouldn't know if has much of an impact, we use a different system now in my project that I don't really understand since I didn't write it. Would be interesting to find out

[golden frigate]

the logic here is validate, if valid test if same, if not same set last outlined off, and set last outlined to the hit component and turn that new thing on

if not valid, just set the thing and turn it on

idk how it would read valud of none

oh wait

i see the issue

[brazen pike]

Yeah, if last outlined isn't valid AND you're looking at nothing then it will try to set it as nothing and then set render depth of nothing to true

[golden frigate]

ill need more states here XD

oh im not turning off the prev thing

here is the blueprint in working form if anyone wanted to see it

[golden frigate]

thx for the help https://gyazo.com/b3f8b8564b92215eae718d3c06ea81cc

[minor lynx]

is there a way to recover when this happens to a blueprint?

the editor crashed and now i cant open the bp

[sage shale]

I'm a beginner so sorry if this seems silly, but I've got a trigger box in my level and I'm trying to get a random point inside the component bounds from it to get a random point in the bounding box but whenever i try and connect the trigger box to the get component bounds bp it says

and I have absolutely no idea what that means ;-;

[thin panther]

So thats a reference to an actor, that wants a component in an actor

[sage shale]

what ado you mean it wants a component in an actor exactly? I'm a tad unclear on that exactly-?

[runic parrot]

Hi! does anyone know if there's a dynamic way to add a static mesh component?
I have a pool of different static meshes, i want to add one of them randomly.

[sage shale]

I assume you mean a component as in it's position, or mesh, or just some part of the object?

[thin panther]

Components are thinfs you add to actors, yk like staticmeshcomponent, or charactermovementcomponent

[thin panther]

Just set the static mesh component to a random mesh from your pool

[sage shale]

ahh okay, so- erm- when it's asking the component bounds it's asking the static mesh bounds?

[thin panther]

Its gonna get you the bounds of whatever component you put in there

If its a static mesh, a box collision etc

[sage shale]

welll- okay how exactly would i get like the bounds of a TriggerBox then? (or is there a better way to do what I'm looking for?)

[thin panther]

Typically i make my own bp for that

But i imagine you can get the box collision from trigger box

Id typically use my own bp that has a box trigger that spawns x amount of ai in it

[sage shale]

i just looked up "Get Box Collision" and in the way like while looking it up I see "GetActorBounds" that... hmmmm ;-;

I wonder if by chance that's exactly what I'm looking for-

[thin panther]

It will be

But if you plan on having more than ome of those zones this implementation wont work

[sage shale]

oh? How not?

[thin panther]

Cause you are referencing that specific trigger box

You would have to copy pste the code for each kne

[sage shale]

ohhh okay, I heard something like adding a for each loop and adding the specific instances of the zones into an array for the code to be executed on?

[thin panther]

Hence why i use my own bp for it, that handles all the spawning on its own

No

Thats a terrible way of doing it

Just have the spawn logic in your spawn zone

Then each spawn zone automatically does it

You would benefit from taking lessons on unreal and basic oop principles

[sage shale]

I know OOP principles I've just never had to do this thing in specific- never done much with 3d games like this :,)) I should also say it's late and I think you and I were talking about different things lol i meant for having every zone happening at once-

But yeah I really should take lessons on unreal, right now I'm just learning by doing random sh*t and figuring my way out from there :p

by all means though if you've got a good tutorial that you think teaches the proper/best practices then by all means, I'll watch it :]

[thin panther]

The best place i can offer are the official unreal tutorials

[sage shale]

I've seen a few like hours long and some random vids about various blueprints but not ever actually any genuinely comprehensible things that teach them

[sage shale]

dooo they happen to be in visual form? I'm a visual learner so like hopefully videos??? :,>

[thin panther]

Yup

[sage shale]

ayeeeee okay where can i find those then???

i have somehow not even heard of their existence 💀

[gentle urchin]

This could be done with a manager class and a dispatcher , informing the spawnzone bp's

[sage shale]

😃 I will openly admit I have 0 idea of anything you just said! : D

[gentle urchin]

A manage is just a class that manages other classes. Usefull whenever you want to control many actors in some fashion

Like a group of swat AI

[sage shale]

interesting- hmmmm good to know, I'll have to look into them :000

is that many actors of the same type or many in general?

[gentle urchin]

Event dispatchers (or delegates) is like a subscription service

Whoever has "bound" to the dispatcher will recieve the event call when the dispatcher is called

[gentle urchin]

More often than not many if the same , but its not a rule

[sage shale]

I hate and love how I understand none of what you say, because on one hand it means that I know next to nothing about Unreal, on the other hand I already knew that and it just means there's more for me to learn hehehehe

[gentle urchin]

Dispatchers dont care about who gets the event , so the caller doesnt need a specific target

You know how subscription works right?

Like you subscribe to a magazine, and you get it every week/month

[sage shale]

uhhhh slightly? oh- i thought with the code it was just whenever the event was triggered not nessicarily just time based

[gentle urchin]

True, it is not time based

It was just an analogy for the principle

Actors must subscribe to your dispatcher

They must put themself on a list that the dispatchers goes through whenever the dispatcher is called

So whoever is on the list, gets the event

[sage shale]

So- okay I can understand the manager class to manage all of the zones but how would a dispatcher help?

[gentle urchin]

Dispatcher would be used to tell all the zones to spawn

Or despawn

If thats what it was about 😂 ill admit i didnt read far up

[sage shale]

Wait why wouldn't the manager class do that

[gentle urchin]

It easily could

[sage shale]

I thought you said a dispatcher recieves an event and does stuff with it not gives the event? Lil confused

Not like recieves it

But on the subscription it gets called because of the event and stuff yada yada

[gentle urchin]

When called, all subscribers recieves a corresponding event

[sage shale]

Right, so all of the zones would spawn the little enemy inside of them. But wouldn't it be the dispatcher that gives that event?

[gentle urchin]

Could be , yes

Keep in mind theres always like 57 ways to a goal

10 of them is prob alright, the rest is probably not 😄

[sage shale]

Hah fair point- My goal is just to learn at least one of them though and i currently do not know them 😭😭

[gentle urchin]

Id check out dispatchers early on

They are very usefull

[sage shale]

Dispatchers and managers then?

I'll add that to the checklist of stuff to check out after i watch an Unreal tutorial :))

[icy dragon]

Dispatchers allows for event binding, e.g. telling other actor to do something

[gentle urchin]

Id prob skip the manager for now , i dont think you really need it for this

[sage shale]

Well not just for this example but i mean it sounds useful for the future so why not learn it :p

OH ALSO pls where is the Unreal Tutorials?? Like the official ones 😭😭😭

[icy dragon]

#ue4-general message

[runic parrot]

Hi! how would you go about making a 1 to N structure of static meshes?
I want to map one Static mesh to N amount of other static meshes and have multiple Row of this.

Oh Dt makes perfect sense.

[sage shale]

THANK UUUU and same for you Squize veryyy much appreciated :)))

[round dock]

is there any precedent for using livelink "locally"?

like, do the face capture and display the driven skeletal mesh on the same phone

rather than porting that data from a phone into an editor

I figure it's possible, since you can track + display the default arkit tracked face mesh on the same phone

[runic parrot]

Hi! is there any way to call one actor function when the game is running from the editor?

[round dock]

like, only run a function if the game is being played in the editor?

[runic parrot]

One actor has Method X with parameters.
I run the game, i spawn one actor, i select the actor from the editor and i call that actor method X

[round dock]

iirc there is something for that but idk where/what it is

one workaround is to have a public bool bFlag in the actor, that you set in the world explorer. have tick check for that to be true

[runic parrot]

Okey so there's a "call in editor" flag on the events, that one does the work.

[runic parrot]

One question! i'm doing a procedurally generated tile map.
Do you think it would be too much to use one Actor (With one Mesh) for each Tile
Or
One Actor with multiple Static Mesh components (The tiles as meshes within the One actor).

Assuming your regular rogue lite map size, i'm not sure how hard it would hit the performance using actors, but i'm tempted to do it in this way to gain functionality on each Tile.

[trim matrix]

There isn't any functionality you would be missing out on if each tile was not its own actor.

Id imagine the greater percentage of tiles are just static anyways.

[plain helm]

Why Enemy HP Widget showing too above head?

[gentle urchin]

Show the widget

[gentle urchin]

Id prob do ism, and just keep an array of tiledata. Then the holder of the given array has any functionality you desire, and can apply it to any tile

[icy dragon]

Mark the function as Call From Editor?

[icy dragon]

Try setting draw size to 1920x1080

[runic parrot]

I did this with the hexagonal map version, prob going for that one same, ty!!

[runic parrot]

I was using it but it didn't work. the problem was that the event can't have parameters.

[opaque acorn]

Is this statement valid? If so then a custom function made in a function library and then put in a macro will be complied every time? Or it will for once

[undone surge]

if i am setting a varaiable in my level blue print like day or night, how would i be able to reference those variables in ohter blueprints

[opaque acorn]

Actually i have a big function

And I don want to complie it multi times per actor like the statemnt in post. But i have to put it inside a macro as function dont support multiple execution pin

Otherwise one have to put branch node manually after the function which may look a bit hassle

To straight my question if i put a custom fun made in fun library then put it in macro , will it complied once or for each macro

[icy dragon]

In C++ multiple execs are just UFUNCTIONS with enums as exec pins

But I digress

[opaque acorn]

I hvae just started cpp so i will not understand

But ofc final goal is cpp

But for prototyping im using blueprint

[plain helm]

really man?

[plain helm]

thanks, solved it

[icy dragon]

Yes.
Draw size in screen space is basically the widget space on screen viewport

[plain helm]

See?

[opaque acorn]

@icy dragon can you put light on the issue i mentioned above

[icy dragon]

How do you assemble the widget?

[icy dragon]

FWIW for prototyping that kind of thing shouldn't be much stopper of a concern.

[icy dragon]

Consider wrapping / replacing the overlay with a Size Box.

[twilit lion]

Hi. I have a string variable, and have multi lines. How can I get a specific line?
Like, Variable.GetString[5] or something like that to get the line at index 5 , but with blueprint.
Thanks

[gentle urchin]

It cant have params, but it can use params

[dull kraken]

Hello, i have made a simple system for head and rear lights it works fine but the thing is when i click play the light is already on when it should be off. however when i use the lights they turn off and then i can turn it back on and off. here is the blueprint

[brazen pike]

Can you zoom in a little bit? haha its really hard to read

[dull kraken]

sure. there u go

oh never mind, such a stupid but simple mistake, i just turned the visibility off hahaaa

[keen saddle]

Heylo Folks. when drawing a debug sphere, is there a way to draw it as an xray or on top of geometry(meaning rendered last)? Maybe i'm missing something. In most case it's fine as is. Though if i have a complex scene, large geometry can occlude the debug sphere and visualizing it is a bit tricky. Making the debug extra large is not desirable. Any input is appreciated.

[serene bramble]

How would I write some kind of knockback? I want to have an obstacle where if you walk into it, you'll be pushed back

[icy dragon]

If player hit the collision, add impulse against the mirror vector?

[serene bramble]

I don't really understand what you mean by that

[plain helm]

Is it possible to use Anim notify state blueprint in actor blueprint?

Is it even a good practice?

I use GAS and it should send weapon hit tag when hit enemy.

I want to implement damaging the enemy when I throw the weapon

How can I achieve this?

[gentle urchin]

A throwable actor with a mesh representation ?

With a projectile component?

[fluid reef]

Has anyone had a problem using the new IK Retargeter and getting your IK bones from the UE4 skeleton to transfer to the UE5 skeleton properly?

[plain helm]

yes it has mesh and projectile movement component in it

[glass stump]

How do I prevent my player from pulling a lever while the lever has already been pulled and is currently animating?
I've tried delays, disable input, etc, but the player is still able to interrupt the animation to restart it.

[thin panther]

at the start of the anim, check if a bool is false, set the bool to true, after anim, set bool false

[glass stump]

Ah, thank you, I'll try it. :)

[pastel rivet]

So is load stream level broken in 4.27?

The node

Because when I use it to load a level, it's all hidden in game? I can see the loaded assets in the outlined, but when selecting them they have hidden in game checked?

Level has to be visible under "levels" tab to be able to be visible by load without hidden in game.. Wow

[tawdry surge]

Yeah. You may want to start loading it into memory before you want it visible to the player

[native falcon]

Hi everyone! I deeply need some help with rotation logic. I'm trying to get this piece of blueprint from Lyra work in arbitrary gravity. Meaning I want to get the same yaw values whether I'm standing on the floor or a wall, ceiling etc. Any help would be greatly appreciated!

[glass stump]

Is 'disable input' the best way to prevent them from pulling the lever again? I have this bool set up but not sure how to actively prevent him from pulling it again (it's still doing it).

[hollow gorge]

what's the difference? Is the first one the window resolution?

[glass stump]

I realised why it wasn't working though, and I can get disable input to work, but I just wonder if there's a better way.

[teal nexus]

I need to spawn bunch of particle systems (once), in the Editor. I made construction script that does what it needs to do, except for spawning. Is there a way I can spawn things in the Editor and not in runtime, using construction script?

[fallen glade]

Every step my character make I spawn a simple bp with a sphere collision (for npc hearing) that destroy itself as soon as the footstep sound is over. I feel like this is bad, is it bad?

[fallen glade]

?

[teal nexus]

I am not sure it's a component

Isn't Niagara system an actor ?

[fallen glade]

can be both

[brazen pike]

I believe unreal has something that can do this for you, a node called make noise

[thin panther]

just stop them doing it if a bool is false

[glass stump]

is there a node for that?

[brazen pike]

branch?

[thin panther]

yes a branch node

[glass stump]

i'm using a branch, but it doesn't prevent the player from interacting with the lever again.

[teal nexus]

It will add particles to my actor-manager as components. I need to place standalone actors to the level.

[thin panther]

it does if you do it in the right place

[glass stump]

i mean it's pretty tight, tbf, they have to repeatedly press the interact button for it to interrupt and interact again so maybe that's just the best i can get.

[fallen glade]

look into engine blueprints I've never made one

[glass stump]

yeah, i'll move things around, i guess it should work.

[brazen pike]

Maybe send a screenshot of your bp?

[hollow gorge]

How would I get an event to play for when the user made changes the games window size manually by resizing the window?

[thin panther]

like in a settings menu

or by stretching the window

[hollow gorge]

by stretching the window manually

[thin panther]

likely in C++

[hollow gorge]

guess I can do a work around with viewport size

[brazen pike]

Is viewport size not what you wanted?

[hollow gorge]

I was initially wondering if such a function even existed, I somehow missed it.

[golden frigate]

Hmmm so the player has keys for doors, different keys

I was thinking it would be cool if there was a more difficult way to pick what key you would use but some methods i thought of have issues because currently when I turn my@head my 3rd person model just spins (I’ll need to change my animation later)

I think it would be cool if u kept the keys in ur pocket and u had to pull all out and click the one you wanted to use from ur palm, but that interaction would probably require like I lock Model movement or something

[gentle urchin]

Picking a key could be an ik target transform ?

[golden frigate]

not sure exactly what u mean by that but i wanted it to be like

press "button" -> reach left hand in pocket and pull out all ur keys in ur hand and hold it out

use mouse to select key u want -> grab key with right hand and put the rest back in pocket

and maybe have a loose IK for the right hand as u move around to pick one

(loose so ur hand doesnt cover the keys)

[gentle urchin]

So whats the problem^^

[golden frigate]

It’s first person

And moving the mouse moves the whole character

[gentle urchin]

Fixed when you make the cursor visible is it not

[golden frigate]

U mean make the player not able to move when doing this?

Or I guess make the mouse not turn the character model when ur doing this

But then u run into the issue of now u spin ur head 360 like an owl

[gentle urchin]

Lol does owls do that

Yes exactly, block movement while picking key

[gentle urchin]

Why would the head go 360 ..

Thats 180^^

Still scary lol

[golden frigate]

If I block movement but allow mouse the logic is the mouse still relates to ur head XD

So if they just try to turn around that’s what it’s implying ur doing

[gentle urchin]

Youd need to block that aswell

[golden frigate]

I’ll try to add some rotation limits on the camera

[gentle urchin]

So the viewport is fixed on the keys

[golden frigate]

Maybe like they press key and now they can still move with wasd

But u r limited in head rotation and head rotation doesn’t affect body

[gentle urchin]

Design choise , sure

Yepp

[golden frigate]

Ppl may be trying to get a key while running from something

[gentle urchin]

True

If its a horror game

They may want to stop looking at the keys and run lol

[golden frigate]

It’s mostly puzzle thriller with some horror

[gentle urchin]

Fun

[golden frigate]

Did lockable doors yesterday now I need the key inventory

how should i go about putting key meshes in random location on the hand?

i was thinking having a finite amount of fixed locations the keys can be on the hand and then randomizing what is where

basically like X sockets or mesh locations and changing the mesh when u pull it out

[gentle urchin]

Sounds fine

Prob wont have 50 keys at one time anyways

[golden frigate]

for some reason the anim montage isnt playing :/

i did this before but for some reason this one just aint right

[gusty shuttle]

Hey, is it possible to import a level into a level that has world partition enabled?? @ me if you know

[golden frigate]

disregard my message i had the wrong BP

might have to play around with FOV or something but its a start

[desert storm]

How do I control material opacity in a blueprint?

[tawdry surge]

You want to look up dynamic material instances

[lusty rune]

Hi i have a question

Why does it not work?

[desert storm]

Thank you

[golden frigate]

any ideas on making the freelooking stuff for fps

[lusty rune]

Maybe because an AI shoots it out?

[tawdry surge]

Probably because it's hitting the capsule before it reaches "player"

[lusty rune]

I tried the capsule too, it didnt worked

[tawdry surge]

If I'm doing something with an actual projectile I usually use overlap events as I find them more reliable.

I'd also just let the projectile worry about telling the player they got hit. Player just needs an event or function to handle the damage

[lusty rune]

If i turn on cast failed, it does well

So i think the problem is with the casting

maybe the FirstPersonProjectile what the player shoots and the FirstPersonProjectile what the AI shoots aren't the same

[cobalt gulch]

How do I play an animation but only for selected bones, im trying to allow the player to still walk with animations because when i play an animation through nodes it makes the feet stay still because of the anim

[tawdry surge]

Id check, and rename them if not

@cobalt gulch animation layers

[cobalt gulch]

With nodes?

[tawdry surge]

@lusty rune But that type of thing is why I wouldn't have the player handle it. If you have 4 or 5 projectile types then it'll turn into an issue with casting

@cobalt gulch montages can be played through BP if you're against the animBP/state machine route

Both allow layering

[lusty rune]

I have only one type

[tawdry surge]

Player and ai using the same one?

[lusty rune]

I think

yes

[tawdry surge]

Well if the cast is failing but works otherwise it seems like the class you're casting to is wrong

[golden frigate]

using a camera manager but for some reason my yaw is locked?

[cobalt gulch]

Is there a guide on this, I can only find blending anims, which is not really what im looking for

[tawdry surge]

[solemn crescent]

Thinking I can add a blueprint to a 2D card actor: on event, reposition card, facing and in front of the camera.

How can I query the cam position and project the card depth and scale?

Two days into Blueprints; only barely know what I’m doing.

[icy dragon]

Just use materials for that.

[golden frigate]

for some reason the pitch is just always 0 using a camera manager

https://gyazo.com/465df9f1929aa871a2f156d90e4c79dd

saw some posts on the forums but they go unanswered

[onyx token]

is there a trick to make a toggle from a signal without using a boolean?

[spark steppe]

flipflop

[coral sand]

i added this to the current level blueprint but when i press F4 in game it doesn't trigger it??

[onyx token]

oooh

thank you! @spark steppe

[remote meteor]

for some unknown reason,

breakpoint doesn't work on level blueprint

[coral sand]

no but i also had a breakpoint on the cpp function it calls

and it still didnt trigger

but it did whe n i changed it to debug key input

[viscid python]

Alright, I have a working pause menu but now I want it to appear as an "ingame" widget in the world (like a floating health bar if you will). How to go about this? I can show the widget in the world but it won't "work" or show any updates when I browse the menu.

[icy dragon]

Ignoring the fact that Flip Flop uses internal boolean, but I jest

[onyx token]

ye, but it lessens

da noodle

[golden frigate]

just tested it even on a plane old First Person BP starter, using a camera manager locks the pitch

found it its a use controller rotation pitch setting in the character that isnt set by default

but now the body model is gone ._.

oh because if u use pitch the mesh will rotate too

then how do i decouple those?

maybe i can lock the mesh's rotation somehow?

[solar bison]

Does remove Child remove ALL the children of that class in horizontal box? in BP?

[maiden wadi]

RemoveChild does not take a class as an argument.

[solar bison]

what's quickest way to get rid of all children in a horizontal box?

i'm looking for 1 node

[maiden wadi]

ClearChildren

[thin panther]

also please don't crosspost

[golden frigate]

any reason using a camera manager would make it so u cant adjust the pitch without making the whole Character change pitch?

[solar bison]

i won't...but it's really annoying that UMG is less active compared to #blueprint . I don't get a fast answer

[rich jungle]

Is there a way to set the default comment box colour?

I want it to be darker, without having to manually change it each time

[pastel rivet]

What you mean by this?

[icy dragon]

Please see #rules and don't crosspost unless redirected.

[slate orbit]

I didnt mean to crosspost

I realized there was a channel for blueprints afterwards

I can delete

[runic parrot]

Hi! I want to measure the distance from any point within this collision Box to the bounds of the box.
I have thinked on using a raytrace to check the distance, but i can't find how to make it collide only with the bounds of the box.
Any suggestion?

[golden frigate]

tiny question, if i make a UMG radial menu can I put it like hovering over my hand in 3d space, instead of just a screen overlay?

(if its possible)

[gentle urchin]

Like.. a widget component ?

[brazen thicket]

Folks, my procedural mesh compnent's collision is broken. It doesn't overlaps

[formal wren]

Hi everyone. Do you guys have an idea how I could bake out PBR textures from a material? The only way I can come up with is unwrapping using world position offset, set material unlit, color to current pbr channel and use a rendertarget to capture

This needs to happen runtime

[golden frigate]

yeah im not sure if the key in hand thing will be good, ill keep trying it a little bit, maybe theres a way to do an approximate linetrace?

like pick the nearest key u r looking at?

cause it looks like this when u are picking the key

the flashlight + ambient character bobbing may make it hard to pick if there is > 3 keys XD

[runic parrot]

Is LineTrace supposed to show on editor or only during play?

[blissful grail]

Depends if it is debug or not.

[runic parrot]

How do i specify it so it shows during editor?

[blissful grail]

Just turn on draw debug type

[runic parrot]

it's on, but i can't see the line on editor mode, only while play on editor.

[maiden wadi]

Exiting play flushes debug draws. To see it in the editor, you need to call it from an editor event.

[manic vessel]

Hi I am trying to set custom relative transforms for attached actors , So I created a map variable that picks the correct transform for the actor. But its not working 😦 not sure why .

[runic parrot]

The show on play mode, they don't on editor. I'm calling it from an editor event.
I'm not going into play and exiting, just trying it on editor mode and it's not showing up.
Works ok on play.

[zinc willow]

Am I missing something? Other 2 widgets were found

[rich jungle]

thanks :)

[golden frigate]

can u swap a static mesh out?

like i have a blueprint for a key can i swap what mesh the key uses?

@gentle urchin like for the keys in the hand i want to set the mesh based on what enum it is

but id prefer to just make 1 blueprint for a key since interactions will be pretty much all the same

[icy dragon]

#cpp

[trim matrix]

Not everything works in editor. The game is not running when you call logic from within the editor and much of the logic in unreal is meant to work during runtime. The main usage of running code in editor is to change the default values on actors in your world. Ex, updating an Actors starting position, changing an actors starting mesh, or changing an custom variable on the actor.

[icy dragon]

That being said, with some C++ work, it's possible to do things in Editor tick without having to play into runtime.

But I'd say only do it if it's absolutely necessary to preview things in editor over time.

[trim matrix]

"On see pawn" event, is this available in UE5? i can't find it

my Enemy AI is a pawn itself, should it be a Character instead?

[golden frigate]

eyyyy

i just made an event to change the mesh on the actor

[torpid mulch]

Guys, was researching something and wanted to confirm here. The ecquivalent of scriptable objects on Unreal are Data Assets? You create a Data Asset and then you can create instances of it to change the variables and configurations of it just like a scriptable object?

[earnest mango]

You can absolutely do that! I'd call SetStaticMesh in the Construction Script, feeding SetStaticMesh a Select node that selects on your EKeyType

[golden frigate]

yeah i got it working i just had to figure out how to get a reference to the thing

[tight schooner]

Roughly speaking yeah. They hold data and can have functions too (mostly used as getters). Mathew Wadstein has a couple YT videos on data assets

[earnest mango]

Oh, heh, didn't notice that picture showing the robot was also you

[golden frigate]

now for some reason when i use my wasd it just freaks out XD

idk wtf happened in between

my editor did crash for some random reason and i didnt restore the changes

maybe that impacted it

[trim pollen]

I have a blueprint that needs to reference a bunch of other blueprints. on my event beginplay, i have a long series of "get all actors of class" -> get -> create variable. Is there a better way of doing this?

[golden frigate]

https://gyazo.com/a9379feeb1875c43460f41991feb2b4d

it just goes wacko when i press wasd now

ok so for some reason putting a child actor caused this weird behavior

[icy dragon]

...are you using child actor component?

[golden frigate]

yeah

cause i wanted to put a blueprint in the hand XD

[icy dragon]

BAD

[golden frigate]

but i want to put a blueprint in the hand

so my interaction blueprint logic still applies

aka it highlights it when u look at it, and does things on click

[icy dragon]

Spawn the actor and set the attachment to the hand socket.

Much better that way

Avoid Child Actor component at all costs.

[golden frigate]

ok so spawn the actor and attach to socket is there a node for that?

[runic parrot]

Hi! does anyone know if there's a way to spawn one actor near another actor and clip it's location to "top, bottom, left, right"?
One should be beside the other, but not touching.

[icy dragon]

Yes, there is, conveniently named Spawn Actor from Class.

[empty needle]

Hi, is there a way to listen to a "Left Mouse" button event?

[icy dragon]

Then execute AttachActorToComponent (I think Spawn Actor itself don't do the attaching on its own)

[golden frigate]

yeah ill try that it just makes it hard to adjust rotation

if its off a little

can u preview a mesh in a socket?

[torpid mulch]

That’s awesome, what I needed tbh, can you link me to any of his videos?

[tight schooner]

Search Mathew Wadstein Blueprint data asset on YT

[earnest mango]

Yeah, but the approach is gonna depend on how the BPs relate to each other. If they relate hierarchically, like a Player BP that needs to reference the player's weapon, you could have the Player BP spawn the weapon and bank the ref that way (i.e. the Player "owns" the weapon). Interfaces are a good way for one BP to talk to a variety of other ones without direct referencing them (e.g. if you want different BPs to do different things when hit by the weapon, you could have the weapon send a HitByWeapon interface call to actors it hits, and then have your BPs implement that function to handle how it wants to respond to that)

[icy dragon]

Yes.

[golden frigate]

i found it

fixed it

[wise tide]

More of a math problem but I am trying to set a progress bar overlay to match my slider. The progress bar ranges from 0 to 1 (0.75 is 3/4 for example).

The following BP works when my slider ranges from 2 to 12, and I tried copying it for a slider ranging from 10 to 200 but it doesn't work.

The math doesn't work for this though, and I am not sure how to make it work.

[faint pasture]

Spawn actor from class -> Attach actor to component (option for socket)

[faint pasture]

Remap range clamped

You could just plug in 10 200 0 1 and it'd just work.

[wise tide]

damn, unreal has some 5head nodes. ty

[gentle urchin]

Normalize : (Value-minrange)/(maxrange-minrange)
MapToRange : ((value-inMin)/(inMax-inMin))*(outMax-outMin)+outMin

Assuming value is clamped between minrange and maxrange

[wise tide]

yes, that's pretty simple compared to the mess I made. Makes me wish I paid more attention in maths lol

[gentle urchin]

Sadly school maths didnt teach me this

Remapping to new range is a tad extra but nothing crazy

[trim pollen]

thanks... i suppose it's sort of a hierarchy. Basically I'm using one blueprint's position to control the position of a few other blueprints. there are a few other functions called in other blueprints though

[runic parrot]

Anyone? D: i did a workaround,but it's shitty and long

[modest monolith]

I have a power up that makes my character run faster for 2 seconds. but sometimes it doesn't respect the delay and has speed buff for longer or sometimes when he returns to normal speed he goes soo slower. Why ?

[onyx token]

is this the correct way to use "Get all actors of class" if there's only 1 of them?

[trim matrix]

That works. There is also a node though called GetActorOfClass

[onyx token]

oooh that ones better, thanks!

[trim matrix]

Im not sure what you mean exactly

Clip its location?

For example, do you mean you want to spawn an actor X units left of another actor?

That should just be a matter of getting the actors world location and adding X units to it?

are these actors all different sizes?

Maybe your trying to find the leftmost point of an actor then add X units to that?

You could get the bounds of an actor to find that.

[trim matrix]

Nobody can help you answer that question unless we see the code that is causing the error

[faint pasture]

There's Get Actor of Class

[modest monolith]

Here we go

[onyx token]

thank you

[faint pasture]

Is your pickup getting destroyed before it can put the speed back to normal?

I wouldn't do buffs like that

just have the collectable add a buff (whatever form that takes) to the character and then its job is done

[modest monolith]

No

[modest monolith]

Oh wait maybe yes... probably the tile gets destroyed and so also the pickup

[trim matrix]

maybe the pickup should call a function on the player that handles super speed

[faint pasture]

Depending on how general you want to get with it, you can approach it a million different ways

Simplest method would be to make a buff actor that adds 1 to SuperSpeed when spawned and removes 1 at expiration

Whenever SuperSpeed > 0, speed is one number. Otherwise it's another

[summer jetty]

Anyone in here good with datatables/enums? I’m trying to pull data about items from the table to show info in a bag slot. It seems to work with some items and not others. But there doesn’t seem to be any logic to why some fail. The data in the table all looks fine. The blueprints for the working vs non-working items are copy pasted with only the bag slot changed. The bit that fails is getting item type from an enum. But it finds and returns one entry on the enum as a string ‘Weapon’ and refuses to find and return the other one as a string: ‘Misc’. I don’t understand why? Shouldn’t both fail if anything?

[faint pasture]

What other buffs are you considering? Or is the speed boost it?

[faint pasture]

Show your table and how you're trying to pull the data

[modest monolith]

Which kind of buff?

[faint pasture]

I mean is speed boost the only buff or are you trying to have others (jump boost, invincibility, whatever else.)

[modest monolith]

Probably in the future I'll add more but I won't have speed problems as they will give other buffs lol

for now the problem is that it slows me down

when it ends

or sometimes it doesn't end at all

[faint pasture]

Yeah because your logic is all fucked. I'd start by making a buff actor or a buff struct

if you do the actor approach, you just spawn the actor and it handles the logic and stacking etc.

[trim matrix]

Neither should fail, I am assuming that there is a issues with the code that gets the item type as a string, can you show that code.

[modest monolith]

It's an endless runner

So tiles behind me get destroyed

[faint pasture]

Yeah we get that. don't have the pickup handle anything beyond the application of a buff

[modest monolith]

Well.. the pickup applies a buff indeed

and nothing else

but doesn't work

[faint pasture]

No, your pickup is acting AS the buff

make a seperate Buff actor

[trim matrix]

Your pickup is acting as the buff yes, the BP that handles the buffing logic needs to be stable

your pickup is not stable as its getting destroyed

[modest monolith]

Oooh

[crude isle]

can someone help me #ue4-general

[faint pasture]

BuffActor

BeginPlay -> ApplyBuff -> Delay(float duration) -> UnApplyBuff -> Destroy(self)
ApplyBuff -> Do shit
UnapplyBuff -> Undo shit

[modest monolith]

And then If I pick up the powerup i have to cast to buff and call the functions ?

[faint pasture]

Do you know what casting is?

In your pickup it'd be like

[runic parrot]

Yeah, let's say i want to place one actor on top of the other one.
I want the new actor base to the The higher point of the first actor.
So there's one in top of each other. Like when you place 2 cubes in editor, but i only have the 2 objects mesh reference.

[faint pasture]

Event Pickup -> SpawnActorFromClass(SpeedBoost)

The end.

[modest monolith]

Aaaaaaaaaaahhhh

Well yeah that's the expert way to do it

[faint pasture]

the speed boost can handle all the logic that speed boosting entails

[modest monolith]

I would have do a spaghetti crap

ahahahaha

[faint pasture]

The expert way would be to use structs or wahtever but actors is the simplest and most flexible

[modest monolith]

This is a well optimized solution

[cobalt gulch]

How can I sort weapons and gadgets in a widget

[modest monolith]

buffs

wow

[trim matrix]

try this node

[modest monolith]

Now i'll do it !

Lemme try

[runic parrot]

I did a workaround that gets the upper bound of the first actor, looks for the lower bound of the second one, takes the height of the seconds one divided by 2 and places it that on top of the upper bound of the first one.
But there has to be a better way, it's insanelly stupid the way i'm doing it

[trim matrix]

how else would you?

[faint pasture]

For your first draft don't bother with handling stacking, just have it add 500 to speed on apply and remove 500 on unapply. Later you can do stacking logic.

[trim matrix]

There is nothing wrong with that way.

[runic parrot]

maybe there's a node like "clip to upper bound" that i don't know.
It sounds so common to me that i think there must be a node for that already

[modest monolith]

what's stacking logic ? you mean that I can stack mov speed ?

[faint pasture]

If you need it to fit tighter than the bounds, jsut start out above it and sweep it until it hits.

[trim matrix]

sadly not

[modest monolith]

I don't think i'll put it

[faint pasture]

Yeah do you want 2 speed buffs to be +1000 or just +500, that's up to you

[runic parrot]

this is actually really good, i can place them tetris style, Ty!

[modest monolith]

so ApplyBuff and unapply i'll make them functions or custom events?

[faint pasture]

Just custom events in the base buff actor

[modest monolith]

Okay

[tired chasm]

Sup yall, got a small question. I need to get the velocity that my character is moving at any given point. There's obviously this node, but this doesn't account for when the player is on top of a moving object. I was just wondering if there was an easy node that has this done before I start making my own solution.

I know it's an easy problem to solve, but I feel like Epic might already have a node for it, but I'm not finding it

[cobalt gulch]

How can I sort weapons and gadgets in a widget

[modest monolith]

https://tenor.com/view/amirite-hadesdisney-hades-gif-5584633

[modest monolith]

.

[urban zodiac]

You can try getting velocity from the movement component instead

[faint pasture]

Where is it getting the Character reference from?

[modest monolith]

from the character

as in the previous

bp

it works by the way 😄

and I can also stack them apparently

[faint pasture]

Ya that looks good

[modest monolith]

but still.. if the buff finishes I lose movement speed

[faint pasture]

Later you'll want to split it between a BaseBuff that does all the character getting etc and specific buff subclasses that do their own thing but that'll work

[faint pasture]

You're saying you go UNDER your starting speed?

[faint pasture]

like if you start at 1000, it adds 500, then it removes 500, and you're under 1000?

[summer jetty]

And that’s the table

[faint pasture]

All that name to string to row name stuff looks gross

[modest monolith]

My run speed apparently return to 1000

but I go slower

like half

slower

[faint pasture]

What is RunSpeed? That's not on the CMC, is it a variable you made?

[modest monolith]

Run speed I mean the variable and not the character mov

[summer jetty]

What do you mean?

[summer jetty]

Should they all just be string type originally instead of converting?

[tired chasm]

seems to behave the same way. I thought I've a node that gets the actual velocity or something but I must be miss remembering

oh well

[urban zodiac]
