blueprint

[distant canyon]

Why do you need to create the asset for?

[wraith loom]

That Adriel fellow said I should do that to automatically create an array with a default values

[distant canyon]

Oh boy

[jaunty solstice]

Any users of Ultra Dynamic Sky?
Does anyone know of a way to toggle to Night mode either in editor or via Sequencer?

[distant canyon]

You can just create a variable on any blueprint

Use contructor script to set values

[wraith loom]

Yeah but don't constructor scripts run every time I start the game?

[distant canyon]

aren't you going to be getting the values from disk though?

[wraith loom]

I'm confused

[distant canyon]

Well, you could stream the relevant values from disk in the constructor script

You're not going to be able to have an actor with an array of 2bn vectors, it's just not going to happen

[wraith loom]

So how do you suggest I store the vectors?

[distant canyon]

What values exactly are you storing? Positions in space?

[wraith loom]

ye

[distant canyon]

and how are you getting those values?

Do you generate them or is there some list you're getting them from?

[wraith loom]

they're generated

with randomizers and a seed

[distant canyon]

Deterministically right?

[wraith loom]

What does that mean?

[distant canyon]

If you run the same generator function with the same seed and value you get the same output every time

[wraith loom]

yep

[distant canyon]

Then why do you need to store all of those values?

[wraith loom]

because I need to make a map, and I need a master array that everything references to

[faint pasture]

You need to make it at runtime if the map has to be able to zoom into a single star

GetStars(FVector Origin, FVector Bounds)

[distant canyon]

Just the map itself will be huuuge if it's a pre-generated texture with all of the possible stars

[faint pasture]

You can render the galaxy and use that, but it won't be very useful lol

That's like having an image of the entire world with a You Are Here pin on it

[wraith loom]

So I did this (dunno how to call it though). What now?

[distant canyon]

Even a really bad map where each single pixel represents one of 2bn stars you're gonna have a ~44721x44721 texture

[wraith loom]

I'm only going to be rendering nearby stars.

[faint pasture]

Then do that

At runtime

You won't fit all the stars into anything, don't even try

That's like saying you want to save 20 sq km of a minecraft map to disk

don't do that

generate it

[wraith loom]

You wanted me to make a new asset and put the array there, I was wondering why I can't put the array in an existing asset

[wraith loom]

It's all server side

[distant canyon]

The minecraft server still doesn't store the entire map to disk

It generates chunks and lays deltas over top

It stores the changes from what is generated, not the generated stuff itself

[wraith loom]

I don't see how I could do that though, especially in regards to the map. I need to get the nearest stars to the player... I can only think of ways of doing that using arrays.

As for the deltas, I was already planning to do it that way.

I just got a brainwave

I was going to split the big array into smaller arrays after the big array was generated, but for some reason I didn't think of placing the vectors into their small arrays as the vectors are being generated

I'm dumb

[distant canyon]

You'll have to generate the vectors per sector (however your galaxy is split up) and just use those

I'd use an octree but any 3d spatial data structure works

You can then store your delta in a separate octree

When you generate the data you check against the delta octree and apply any matches

And cache the currently loaded sector or something

Doesn't have to be octrees, that's just an example

[twin perch]

Hmmmmmmmmmm well i found out that unreal engine 5 doesnt like spawning in 10,000 actors at once.

Lol

[lunar sleet]

Done right, it shouldn’t ever need to

[tidal galleon]

So I have a math question. More specifically rotation.
I want to move this lever on the Z-axis in the direction the player is moving. So the lever moves with the player.
(Think Sea of Thieves and the anchor wheel)
I have provided an example of what I'm looking for down below.
I know it has something to do with getting the Forward vector. But translating that into the Z-axis has been a pain.
Any help would be appreciated

[faint pasture]

How does your data get generated to begin with?

[elder lodge]

Now you're going to search and sort thru the array of billions 😭

I think take some algorithms courses
You'll learn how to optimize for such ideas

[elder lodge]

Could you just tie its rotation to a player collision? Based on the angle of the players movement to the axle center you will know which direction to push

[tidal galleon]

Which nodes would I use?

Im coming from unity so Im still trying to figure out what nodes are what.

[elder lodge]

On collision overlap or hit event nodes
Break the hit results, find the hit location and normal
Which you can use to geometry out whether it's the top or the bottom lever
then add local rotation node.

Or you could hack it by just making the top and bottom collision boxes different and simply rotate left when overlapping the top one, etc. probably don't need the mathy version

[earnest vigil]

Hello I am currently using this to check if an actor is on screen or not, but I need to know if the object has something else in front of it like a wall etc. Any ideas on how to achieve this?

[tidal galleon]

Hmmm okay!

Its a first person game so it looks like this

So if the playing is looking that way the pole would rotate in that direction

[earnest vigil]

Seem to have achieved this by adding a second branch after the first one to check if "Was Actor Recently Rendered"

[elder lodge]

This is massively overengineered
Do a line trace to the object to test if there's anything in between
Then compare the angle between forward vector to the object and see if that is less than the angle of the cameras FOV

[elder lodge]

This

[silent citrus]

I want to use Object class for a one time event, is there a way to destroy it after I execute the event?

[frosty heron]

Get rid of all the reference to the object, it will be garbage collected

[broken lynx]

Im trying to make a simple elevator here, but this is causing the elevator to go diagonally to the side, rather than upward. Not sure what the issue is

lmk if yall need more info

[silent citrus]

makes sense thanks

[keen ore]

I'm just starting out with unreal and copying the pick mechanic from first person shooter starter cotent. I got stuck trying to figure what this weapon reference is referring too.

[broken lynx]

Hey I managed to figure it out, it was setting the default screen root as the target that was causing the issue. If anyone know why that is, I would love to know

[frosty heron]

You can read the type, it's a reference to bp weapon Co class

[keen ore]

can i just skip this step and include in base weapon bp

[frosty heron]

No idea what you mean

[keen ore]

can i just inlucde the code from the weapon refence bp and the weapon pick up bp in the same bp

[elder lodge]

Are there transformations between the elevator and the scene root or the world? Something must be rotated

[broken lynx]

The only thing that I changed was the scale and the positions

[frosty heron]

I don't know, what you are doing but an object reference is useless if you don't set it

[keen ore]

kay

[broken lynx]

I do know that I exported it wrong and that the origin point of each model is around 100 cm off from the actual model, but I didnt bother fixing it since im just making a temporary scene rn

I can fix it now to see if that was the issue

[elder lodge]

Definitely something like that
Can be worked round as you've seen

[broken lynx]

Thats weird...

I fixed it and it still happens

oh 🤦‍♂️ I never applied the transform in blender

uh nope, im not sure what the issue is then

[broken lynx]

Got it working now, seems like that was the issue and now I feel stupid, thanks for the help

[wanton prism]

How do i set it up to target only one type of the class?

[elder lodge]

Get a reference to the object

[wanton prism]

Works now but the closed event doesnt

[keen ore]

How do i actor get destroyed on the sever side

[solar badger]

How would you go about attaching a skeletal weapon to a skeletal character?

Is this something no one has done before?

I feel I may be breaking ground into a new frontier

[frosty heron]

U tell server to destroy the actor. Where ever you do it just make sure the server is calling destroy actor

[spark steppe]

you attach it the same way as a static weapon

[solar badger]

Can you explain this?

[spark steppe]

no

[solar badger]

Well

[spark steppe]

it's explained in 1000 tutorials

[solar badger]

If I pick up a static mesh

I can connect it to a socket

Easy

Done

[spark steppe]

same for a skeletal mesh

[frosty heron]

U can do that too with skeletal mesh?

[solar badger]

At runtime?

[frosty heron]

Sure thing

[spark steppe]

of course

[keen ore]

how would i tell the sever to destory the actor

[spark steppe]

you wouldn't

because that's the first thing going to be exploited by cheaters

and bad design

the server DECIDES what to destroy

[frosty heron]

You call destroy actor on server side

I mean like Ben said , shouldn't let the client tell the server what to destroy

The server have its own world and its the one that hold the truth so to speak. So let server destroy actor when it sees fit

[spark steppe]

also the pickup happens on server, not client

because i guess from the screenshot that you may also do this on the client right now

[solar badger]

You saying if I create a completely typical static mesh pickup setup but just use skeletal instead, it’ll work?

Because in past I have and get told by unreal that it’s not the correct type of actor

[spark steppe]

then you did something wrong

probably picked the wrong variable type somewhere or whatever

[solar badger]

I find it funny that every one of the 1000 vids there are

None of them try a skeletal mesh to skeletal mesh

[spark steppe]

because 90% of people are happy with static stuff, and cheats like WPO etc.for animated parts

[solar badger]

Kinda wack. Can’t do much with static

[spark steppe]

you can do a lot with static

and some shader magic

[solar badger]

Static mesh whip challenge

Alright jokes aside I’ll give it a shot Ben… maybe I’m messing up something else

I technically have it working

[spark steppe]

but also not

[solar badger]

But I spawn the mesh at begin play

And then transform it to the socket location on pickup

Which is not clean at all

So looking for like a not hacky way

[spark steppe]

actually i'm kinda convinced that one could make a better looking whip with materials and static mesh

compared to the deformation a skeletal mesh would give you

[solar badger]

They do end up pretty ug

But it’s all skill set at that point I guess

I’m more animator than developer that’s for sure

[spark steppe]

then good luck getting your whip behave like you want to 😄

[keen ore]

Well it works put just spawns a buck of cpies of the ak

[solar badger]

Well moving the thing right is easy

Getting stuff with bones onto a socket seems to not be

[keen ore]

nvm

[solar badger]

But idk maybe I was in a fever dream of dumb mistakes and it’s like a sec evident thing to do

[keen ore]

it my pick up code spawning the extra weapons

[solar badger]

No one on the internet has ever attached two skeletal meshes

So it’s not like there’s much reference

[keen ore]

not the destroy code

[spark steppe]

no one ever

[solar badger]

Like for real tho

Apparently I’m breaking new ground here

Completely new frontier of development

Never before seen rlly

[spark steppe]

https://tenor.com/view/your-brain-is-magical-making-the-cut-you-are-so-creative-your-mind-is-magical-the-way-of-your-thinking-is-magical-gif-22359300

[solar badger]

It’s a funny thing to not have a tutorial on is all I mean

Considering it’s like

In almost every 3d game

[spark steppe]

maybe no one bothered to make one because it's so trivial?

[solar badger]

Well there’s tuts for static meshes lol

So I guess it’s even easier than that!

[spark steppe]

make one then, spread the word

[solar badger]

I’ll report back if “just use skeletal” solves my problem with using skeletal meshes

[keen ore]

so i think issue is with the client telling the sever that client already has a weapon

[frosty heron]

You Do the pick up and verify all on server side

Client just reflect on the state

[spark steppe]

you shouldn't make a multiplayer game imho, or watch a lot of tutorials, guides, books, whatever...

[frosty heron]

Like make the weapon variable a repnotify

I would not make a fps multiplayer with bp only, that's for sure

[spark steppe]

the server is the authority in a MP game, your clients pretty much render poop

[frosty heron]

You have to deal with a lot of technical stuff

[spark steppe]

and ask the server if they can do certain things

the server decides if a request to do something can be fulfilled or not

[keen ore]

I'm not planning on making a pvp thing just for co-op

[spark steppe]

server = mom, client = children

[frosty heron]

Even for co op and even if you don't care with cheating, if bp is your only option consider not doing fps. At best you can do turn based game

[earnest vigil]

Got a weird issue. I am rendering this bounding box and some points to show the 8 points of the bounding box around an object on screen. The picture that is working correctly was taken with a regular camera, but the picture with the objects way off from their bounding boxes was taken from a cine camera. Any thoughts on what might be happening here?

The points and green boxes are being rendered using the current screenspace for reference

[keen ore]

I figured it out

[serene sail]

i have a road spline blueprint setup that does not have collision can someone help please ,the simple collision for the mesh is already present and working when i put the static mesh in the scene

[crystal flax]

hey there i want to rotate this cylinder always but i am not able to do so i use physics constrant but not working i dont want to use event tick if there anyone could help me really appreciable

[thin panther]

Why don't you want to use event tick?

You want something to move smoothly across time. That is tick

[marble tusk]

Are you enabling collision on the spline mesh? I think you can in the details panel of the add spline mesh component node

[crystal flax]

i m making this project for mobile and it will be endless spawnner that is why it will lag

[thin panther]

No it won't, and you can't possibly guess that.

A single event tick rotating something will not meaningfully harm performance

If it is revealed that is the cause through profiling, then sure. But you gain 100x speedups by just not using blueprints if this is your concern

You're in BP land, the things you make there aren't a performance concern

You can also rotate it through materials of it's purely visual, or use the rotating movement component

[glass blade]

Anyone used ue5 blueprint header preview to nativize blueprints?

is it better than plain rewriting BP in C++?

[thin panther]

It's a useful start, but it isn't going to get the important bit, the logic

Writing the header is the most minimal bit of a translation

[lunar sleet]

Still waiting on Eren

[glass blade]

I get that it won't do all nativization work automatically like in UE4's BP Nativization.

[crystal flax]

okay i will try that

[dark drum]

It's more about what and how much you do on tick. Updating the rotation of a cylinder in most cases would be fine. Updating the rotation of 10,000 maybe not.

For what you're wanting, I would just use tick or do it through the material if it's just visual (collision doesn't need to update with the rotation).

[crystal flax]

okay as it is for endless i at real time only 5 cylinder will be rotating not more then that and i cant use material bcz i want feel also like player fall don if not made a balance

[crystal flax]

https://www.youtube.com/watch?v=61r5hHrKu10&t=187s

in this video it is moving without any force i just wnat like this

[dark drum]

If you want it like in the video, follow the tutorial. 😉

[crystal flax]

i am following but my is not moving

in starting 4 minutes only it shows how to do i did exact same but mine is still at one lace only

[shut compass]

I am still trying to figure out the works with blueprints. Feel I am lacking some fundemental understanding of the data types. How would I add a new attribute to my PCG points? I have imported the PCG data collection, specified which pin to grab the information from. Running through a quick loop to store per point the index relevant to the point. I am then getting the value I want to store in an attribute on the point based on that index. But what node do I use to store the attribute?

[marble tusk]

That might be a #pcg-framework question

[keen widget]

why this works, but this does not ? 😦
making litera string and plug it as value works
but typing in the "default window field" does not

[onyx vale]

Hey everyone! I ran into a gravity issue.
I have a regular character with a regular movement component. When I jump, the character jumps to a certain height.
When I double the gravity scale for the character, using the character movement component, the character still jumps to the same height.

Any ideas? Thanks!

[onyx vale]

Also, all gravity related checkboxes I could find are turned on - Apply Gravity While Jumping etc.

[silent stag]

Hey , i want to cancel firing while the inventory winget is open. How can I check whether the widget is open or not?

[dark drum]

They should function the same. How is it used in the macro?

[dark drum]

How are you handling the jump?

[onyx vale]

The character's jump method

[dark drum]

By cancel do you mean stop the input key from firing?

[silent stag]

Yes

[young meteor]

If you have a reference to your widget already which I'm guessing you do since you opened an Inventory (widget), you can probably use this node and input your widget?
I'm no expert though so test if it works. 🙂

[distant hollow]

This is on my BP_Door
My BP_Door is spawned on my BP_DrawnWall on load structures
The Door and the Wall did not change positions
Why did this still get triggered?

[onyx vale]

If you're using the enhanced input system, you can override your input mapping context when the inventory is open

[dark drum]

Assuming you're using enhanced inputs (which you probally should be), you can have two input context mappings. One that contains the inputs when the inventory is open and another which is the default input.

When you open your inventory, you can just add the inventory ICM and remove the default one. When you close add and remove the relevant ones.

[dark drum]

I'm not sure why it would be behaving differently. It should work the same as far as I know.

[dark drum]

Odd, I've not had any issues changing the character gravity on the movement component.

[silent stag]

Thank you for all answers

[dark drum]

Overlaps can trigger by something spawning inside the volume. It's not just based on movement.

[onyx vale]

I'm working with paper2d, so the character is a sprite, and I'm calling the jump method through GAS. These are the only changes that come to mind

[distant hollow]

But this is an Exit, not entry.

[dark drum]

O yea, i miss read that. Print the name of whats leaving, it might point to whats happening.

[proud mauve]

Hey guys, how can I sort my array by the substring? It's just a 2 digits number^^. UE 4.27

[steady night]

hey how would i geed the speed only based on the forward vector *

since when i "sidestep" now i still get speed

[dark drum]

Multiply velocity by forward vector then get vector length?

[steady night]

could it be that simple xD

well no

[dark drum]

What does it give you?

Hmmm, it looks sort of right. You move the camera a lot so its hard to tell.

If the character is facing along the X and is moving on the X, X is preserved. If they're moving on the the Y, the Y is zerod out leaving only the velocity that's along the forward vector.

It might not be what you're actually after. What are you trying to achieve?

[steady night]

ok ill show u , i have 2 modes kinda first one is w,s,a,d run towards that direction but when entering "zoom" mode then w,s is back forth a,d is left and right based on camera and since its messing with my Anim Blendspace since its giving speed when sidestepping (wich it should really) but in this case i dont want it to give speed when A,D

@dark drum

https://gyazo.com/d2fbf9057142af18738c8b2799a9fd8d

[dark drum]

The values are cut off in the video. Also, on you're print string, enter a key value. 😉 It'll cut down on the print spam and make it easier to read. 🙂

[steady night]

aye but u can ignore the values really

altho

i could just check for if W,S is down then calculate speed

[dark drum]

You can't, if the value is correct then its an issue with how your using it. Or you're needing something different.

[steady night]

yeah

[pulsar vigil]

guys how do i filter the result and select only one component from a get component array return, that would permit me to not use event tick in so many bp, a game frame changer

[frosty heron]

I have doubt your frame will be affected.

[pulsar vigil]

oh i see

[frosty heron]

You are just accessing a bunch of pointer

Any reason you need to do it on tick regardless?

You can just grab one from the list and promote it as variable

[pulsar vigil]

but u dont have the full picture, i use event tick set actor,skeletal and component set for many bp,if i have this get working i can get it from specific event

[frosty heron]

Not that tick is evil, there are things that only belong to tick

Why do you need to set actor qnd skeletal mesh on tick?

[pulsar vigil]

thats what i want but im a nooby

[frosty heron]

It make no sense to me that you have to change those assets every frame

[pulsar vigil]

thats right but because i dont know how to do it another way lol thats why im asking this

[cyan bone]

Im using Begin Overlap to start combat.
But then I have the option to still retreat, or move the unit away.
That works when i click away. But if the player clicks in the direction of the units attacking itself, it will overlap the enemies.
How do i prevent this?

[pulsar vigil]

i need to sow u my bp but i have only one hand to type and screen my cat is on me

[manic crane]

Not sure if this is the correct place to ask for help, but here goes nothing:
I tried implementing a grab feature in my game, it works fine when I move forward or move the object around in the air, but as soon as I go to the left or to the right, the object I'm holding does these very sudden and noticeable jumps, any ideas how could I make it smooth like in Gmod for example?

[frosty heron]

Take your time to learn object oriented programming. That's what bp is.

Things to know to get you started on building game.

1. Variables, references, structs
2. Functions , custom events
3. Casting, blueprint communication
4. Event dispatcher/delegates
5. Inheritance

After that you can move on to
Data tables, data asset, interface, components etc

[pulsar vigil]

im already using all of that and i learned it, i understand how it work im just asking how u isolate a component from that get cause rignt now i set the component i want directly on the trace event that is obviously on event tick cause i dont know how to extract it, if u tell me i need to learn array its ok but if u have a quick answer i take it
i also have no time and only learn by practicing, especialy since concept are cloisoned in bp anyway

if i miss a fundamental piece ill go find it and sorry to be blind

[cyan bone]

Oh i know what im going to. Its a sphere trace in the direction im moving. duh

[frosty heron]

You can always use get node from the array return value but you will need to figure out which of the components in the list you want to grab.

[pulsar vigil]

ok i try that thx !

[frosty heron]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Actor/GetComponentbyClass/

There is also this btw. This one will just return the first object found that match the filter

[pulsar vigil]

thx!

[elfin lagoon]

i got this warning for the static enemy pawn (tower), which dont have any movement instructions
its because of Movement Component of this Actor, or i miss something else?
and how to fix it anyway

[thin panther]

Click the collision cylinder and set it to moveable

[versed sun]

In the Details , change the Mobility to Moveable

[elfin lagoon]

it dont need to be movable

[thin panther]

Except it literally does, because it's telling you

[elfin lagoon]

it says "if you`d like to move"
i dont

[thin panther]

But you're trying to move it

That's why that warning is appearing

[elfin lagoon]

thats why i'm asking
i dont try to move it

[thin panther]

But you do

There is something somewhere moving that

We don't know where, but there is

You have to find it, and remove it if you don't want to move it, or set it to moveable if you do

[flint blade]

Hi - I'm trying to create a blueprint event that is triggered by the sequencer. The intent is one the trigger occurs in the sequencer, then the blueprint will loop throguh all static meshes within the blueprint, and transform their position by an amount. The intent is for the animation from the original position and the transformed position to be smooth , with each object also animating concurrently, though with a delay between each element. This is what I have so far, but it is very "jenky" and not really doing what I am after. Looking for a smooth effect as show in this video https://www.youtube.com/watch?v=k2lfuiYmT0w&ab_channel=V5D. Thanks

[frosty heron]

The warning comes when you try to move it.

[elfin lagoon]

its obviously
but i dont move it
and i need to understand, where is this movement instruction can be

[versed sun]

do you Set Actor Location? Add Offset? anything like that ?

Rotation

Change Scale?

having a Movement Component or not has nothing to do with Mobility afaik

[elfin lagoon]

actor is procedurally spawned, do u think its a reason?

[versed sun]

yup, set your Default Scene Root to Moveable

[elfin lagoon]

can anithing go wrong, if i have it Stationary ?

[lyric rapids]

How do you refrence somethign from your level blueprint in another blueprint

[surreal peak]

You don't.

You generally avoid using the Level Blueprint.

Why? Cause for one it's not accessible from outside in BPs. And then, if you need the code somewhere else, you will start duplicating, which is bad.

[proud mauve]

@lyric rapids For referencing you can also use "All Actors of Class" - Node. But NOT on tick^^

[surreal peak]

That is still a somewhat ugly fallback

There are several ways on how one can design a system that properly references other actors.

[dark drum]

'Get All Actors of Class' node should be avoided where possible which would be 99% of everything you do.

[surreal peak]

One way would be having a Manager on some easier accessible Actor, such as GameState.:
That Manager can be an ActorComponent.

And since the GameState is easy to "Get", one can use the BeginPlay and EndPlay of a given Actor BP to get the GameState, get the Manager and add/remove themselves to an Array.

GetAllActorsOfClass is fine'ish. It's using a Hashed Map and is not as bad as most people make it seem.

I just don't like it if people use it everywhere instead of learning better alternatives.

[pulsar vigil]

thx for ur answers that debloqued my understanding, it work now 😄

[dark drum]

Thats pretty much what I do. I have important actors register themselves into a map (Name/Actor) which I can then easily get stuff by name. (assuming im not making a specific manager for them)

[dark drum]

I would imagine it would depend on how many actors you have in your level. A few thousand it would probably be nothing compared to a few hundred thousand.

[surreal peak]

It's hashed by class

So it's somewhat fine

[mortal palm]

how to get a Get node for a variable with valid/invalid branches? (instead of doing get/branch/is valid)

[dire frost]

get the var, right click it and choose "convert to a validated get"

[mortal palm]

thank you

[silent stag]

Hey , do you know any proper aim down sights tutorial ?

[mortal jay]

Is there anything here in my quest object that would prevent me from saving an array list of it? I have all my player data saving fine up until this list. I have all the data types, including the array itself, marked as 'SaveGame', but I'm seeing an odd issue where it saves fine if I leave the game running, and do a load without closing. But if I open a new game after saving, the quest info only does not re-populate (while other player data still does). I'm 99% sure that I'm not resetting my quest data anywhere else.

[brazen pike]

If thats a struct, I believe you need to mark all the struct's members as save game

[mortal jay]

Yeah, all 3 of the structs here also have all of their individual values marked as save game

[brazen pike]

Hm. Then I'm not sure. Access the save game and see if the problem is serialisation or deserialisation

[mortal jay]

So I put print statements to spit out how many active quests are there on save (it showed 2, correctly). Then I did a load in game, and the print statement showed 2 loading from the file, correctly. Its just when I start a new game that it doesnt seem to pick up the quests anymore.

Looked through all my code and couldn't find anywhere that I might be resetting it by accident, so I'm a bit stumped now

[brazen pike]

Whats in quest info?

I know JSON has a hard time serialising sometimes. You can't really serialise objects or actors afaik (in terms of references, you can of course save whats in actors/objects)

[mortal jay]

Ohhh. That might be my problem then. The object in my screenshot above is an actor

[brazen pike]

Well thats probably not the issue, you can save whats inside actors. I just don't believe you can save an actor as a whole (like you can't save game a reference to a spawned actor)

[mortal jay]

I'm trying to save this array of a blueprint class that contained that data,

[brazen pike]

Ah yeah you'll struggle to do that

[mortal jay]

Ok, thanks. I'll switch things up with that then and see if I can get it working with another datatype

[brazen pike]

Do they need to be actors

If they just have data on them, would be better to make them structures

[mortal jay]

Not really. I did it because I had some events specifically for them. But those can be moved elsewhere and I can just convert it to a struct

[lyric rapids]

why am i getting these errors

[brazen pike]

hmmm delete them and get the reference again? BP can be weird sometimes

[lyric rapids]

yeah that worked so is that just an unreal issue

[brazen pike]

did you change the class in "get actor of class" without changing the variable name

that might do it

[lyric rapids]

no

[brazen pike]

Hmmm then weird

Unreal likes to make assumptions about variables based on how you get them, so sometimes if it gets confused just delete them and get it again to give unreal another chance

[rich locust]

probably a stupid question, but is there ANY way to delay construction script execution?

[jaunty solstice]

Need some Blueprint feedback. I am trying to edit BP_NightMode in the CitySample project so that in editor night mode is active.
I know I need to move some logic into the Construction script but not sure exactly what is needed.
In the attached you can see a Custom Event 'Set_nightTime' and at the end of the node network a Boolean SET for Is Night.

[brazen pike]

You probably need all of it? I can't quite read it but it looks like that code darkens the skylight, fog and something else before making the sky itself darker. The "IsNight" boolean is probably just for other blueprints to know when the rest of this code has already been executed

[brazen pike]

What do you mean?

[forest spade]

Hey guys, whats the rule on promoting event inputs to variables if they'll be used later in that event? In this example, the inputs will be used in a function on the anim blend out which can be like 4 to 5 seconds after the event is triggered. Should these be promoted to variables at the start ideally? Seems to work fine, but wondering if its good practice to promote. Thanks!

[rich locust]

i mean literally delay construction script execution

[brazen pike]

What do you need to delay it for? I've never seen that done but there might be another way of doing the same thing

[brazen pike]

Unless passed by reference, each variable will be the same as when it was executed.

[rich locust]

well, i have an object distributor that works by line tracing against PhysMat of the world, and thing is, on level load, apparently PhysMat isn't being loaded yet, but line trace already begins, so Trace gets wrong physmat information, and spawns objects incorrectly (like grass on a concrete road etc)

[brazen pike]

Can't use begin play? or wait until everything is loaded then execute it?

I always just use an actor then on beginplay

[rich locust]

if i use begin play i won't see the result in-editor

i need to see if everything is spawned propely and isn't clipping into things

i tried doing multiple "safety-counts" before looping for like 5-10 times if it doesn't get the physmat it needs, but that also didn't help

[brazen pike]

hmmm there's almost certainly a bool you can check against. Similar to pre-construct has "Design Time" in UMG

[rich locust]

i'm guessing ActorTick wouldn't be it?

[brazen pike]

If you can't find anything else, you could move everything onto a function then label that function as "call in editor". Then you'll have a button to call it in editor to check if anything is clipping

[rich locust]

yeah, i already have a "proxy rebuild" but i'd have to do it manually for every instance + when i bake level out, it runs CS like if the level is just loaded so result is kinda negated

i was thinking maybe moving it to PCG, but i'm not sure if it can allow for per-instance assignin of meshes n such?

[brazen pike]

Is every instance inherited from a base class? if so you can create a "manager" to get every actor of class and call that preview function

might be slow but you're not looking for speed in editor

[rich locust]

every instance IS the same class, i mean every instance that is placed on a level

[brazen pike]

then it would work then, no?

[rich locust]

manually updating all of them every time i load a level isn't exactly excitin tbh

[jaunty solstice]

Hoping someone here has experience with the CitySample project.
In particular migrating to an empty project to reduce size.
You can migrate just the SmallCity level to an empty project and cut the total size in half.
The problem is some functionality, ie especially BP_NightMode, is broken.
The editor always crashes when I try and open.
Tried migrating just BP_NightMode but no difference.

I'm having difficulty getting the On Begin Cursor Over event on a static mesh to fire. Mouse over events are enabled on the controller. If I try to run a begin cursor over event on an attached actor component on the owner actor, it works fine.

However if I want the begin cursor over event to fire on just the static mesh, nothing is happening.

This is on the actor I want to hover over:

And these are the collision settings:

Am I missing something?

[oak fable]

hey there
so im trying to make a turn in place system
my movement is driven by root motion and i locked the character to always face the same direction as the current view, it rotates with my mouse by other meaning
the issue is i dont know a good approach for this i tried to do it this way as i showed in the screenshots but the thing is it would play it twice when switching the bool is done
so do anyone knows a good approach for making it
thanks for the help in advance ❤️

[quartz tapir]

nvm I think I figured it out. Collision wasn't setup correctly on the sphere component.

[olive yarrow]

Y'all... I've spent the last 5 hours messing around with tuts, blueprints and the Mountea framework and i'm having the damndest time just getting a simple bloody dialogue system going. I feel like a damn novice. Anyone got anywhere they can point me so i can just get this garbage done with and move on?

or is this #game-features-system ?

[fair magnet]

Why exactly is my character not moving like I would expect him to?
I've copied all settings from the third person template and yet it's still not rotating.
Any ideas?

[runic terrace]

Set use controller yaw to false in character settings

[fair magnet]

that's looks indeed better yea :) Thanks

[quartz tapir]

So I'm making a basic tower defense game - this is on a widget blueprints event graph. Button gets clicked, spawns a tower, tick function tracks where the tower is, then when it's placed, it sets it to the last known posistion. Should this be in the Widget BP or should it live somewhere else?

[runic terrace]

It's usually better to keep game logic outside of widgets

[quartz tapir]

So, better to make an interface and call it from the widget and have the implementation happen on either the character or the controller?

[runic terrace]

Yes, the game logic is easier to keep track of when the code isn't scattered through multiple widgets

[faint pasture]

The widget should just tell something "hey spawn a tower"

widgets should be an interface with logic, not logic itself

[zealous moth]

yeah i usually put overhead continuous logic in the game instance and have my widget tell my game instance what to do. Like save game for instance

widget logic is just "make my button blue and when i press it do that"

[faint pasture]

Basically make the code work without the widget, then just have the widget call into that code

[quartz tapir]

Yeah that makes sense, sounds good!

[north rain]

I’m not sure where exactly to put this is, but I’ll start with here.

Question: I am working on an algorithm that will sort 2d rectangles into a 2d rectangular container. I believe I have a good general idea as to how to accomplish this except for the first step. The first step involves detecting every corner in this container. I have to do this after every time a box gets placed into the container and the corners of the container change because of the new box. I was wondering if anyone has a good way to detect the corners in the scenario. Thanks!

[runic terrace]

Is this for UI like an inventory screen of some sorts or for a 2D game, it depends on what you're trying to achieve

[north rain]

In this game, there is essentially a truck bed and I want it so that every time the player either takes a box out, or puts on in, the truck bed will organize itself so as to make as little wasted space as possible. The boxes will not be able to be stacked on top of each other, so I’m trying to treat it as a 2d container and boxes, but they are comprised of 3D objects

[pallid gorge]

Does anybody know an easy way to weight an EQS test for the sides of a target rather than the front or back?

[runic terrace]

Are the sizes of the boxes identical?

[north rain]

No, I’m treating it as if it’s random

[fluid flare]

How the hell does Pose Caching work in the UE5 Control Rig? It doesn't make any sense to me

[north rain]

I have a video that kind of demonstrates what I’m going for

https://youtu.be/iKfPHCmpYJE?si=GiUH57dTOF2fP4bA

[runic terrace]

So you need to get the corner coordinates of the truck bed?

[north rain]

Yes, but also the coordinates of new corners made of the truck bed and the previous boxes placed in it

[runic terrace]

Does the truck bed expand or shrink? Why do you need the new corners
You can convert world coordinates into local coordinates by using the inverse transform nodes, you could add a scene component to the corner of where the truck bed is supposed to start and get the 3d coordinate from that, just ignore Z and you have your coordinate. Add width & length to get the other corners

[spark steppe]

just use a "collision box" and disable collision of it, then get the component bounds

or a invisible cube mesh

[north rain]

No, it does not change sizes. I need new corners because the truck bed reorganizes every time the contents change, which means I need to re-detect corners after each box is placed so that I am able to place the remaining boxes too

[runic terrace]

Oh I see

I don't know how that algorithm works so now assuming the newly added boxes kind of subtract space, creating new corners, right?

[north rain]

One friend of mine who’s an artist suggested possibly using the normals of the boxes to see when they’re perpendicular to each other, but then I’d have to account for whether those two faces are actually touching each other and where that point is.

[north rain]

Yes, that is correct

[runic terrace]

I think in this case the 3D Boxes should just be for visuals and not be included in the algorithm logic

[atomic salmon]

This class of algos is known as 2D rectangle packing

https://github.com/TeamHypersomnia/rectpack2D

Among the applications is texture packing for videogames

[north rain]

Yah, I’m trying to treat it as a 2D problem to figure out the 2d positions and rotations of the boxes, and then once the algorithm has found all of them, they I’ll go and place the 3D boxes into their locations

[runic terrace]

You just need dimensions of the boxes, won't their position be handled by the algorithm?

[north rain]

That does look promising too

[lusty shard]

Hi! Making a drone racing prototype using checkpoints (CPs) Screenshot is a CheckPoint BP of a drone passing through. I am trying to prevent triggering any events if the drone tries to enter the CP backwards. To do this, Im trying to compare the difference of global rotation values between the "OtherActor: Drone" and the CP. IF the CP and drone are close to facing the same direction (acceptable threshold), trigger countdown timer of next CP. If greater than x(difference in rotation), do not trigger. How should I compare rotation?

I have tried GetActorLocations and GetForwardVector... but GetForwardVector node is giving me weird decimal x,y,z values and z does not seem to represent world z rotation. Not sure how to use it for this.
GetActorLocation, when comparing (subtracting) gives unpredictable values, even when forcing to absolutes.

I think this math is really simple and I am overthinking it probably.

[runic terrace]

What if they just move backwards while facing forwards?

[atomic salmon]

@lusty sharddot product between the drone forward vector and the checkpoint forward vector

[north rain]

The algorithm also needs the dimensions of the boxes to check if they’re overlapping and check the distances between the boxes.

[atomic salmon]

or normalized velocity vector of the drone if you want to check the direction of movement

[runic terrace]

Won't using both forward vectors for dot result in a false positive if they're facing exactly the other way?

[atomic salmon]

@runic terraceyou need to look at the sign as well as the magnitude

Positive signed they are oriented along the same direction, negative sign they are oriented in opposite direction

Best in this case is to use the normalized forward velocity vector, assuming there is movement

[lusty shard]

there is movement

[dim agate]

Anyone have a clue as to why swapping mapping contexts would cause a camera to get stuck when lerping between two positions?

[atomic salmon]

so check the dot product between the normalized forward velocity vector and the allowed go through direction of the checkpoint. if the sign of the dot product is positive and the magnitude is, say, > 0.5, the drone has gone through the checkpoint in the allowed direction. If the sign is negative and the magnitude is, say, > 0.25, it has passed it in the opposite direction

[lusty shard]

ok so maybe somehting went over my head. you said to compare the velocity to the forward of the gate?

Do I need a compare node then?

[atomic salmon]

You need to safe normalize the velocity vector of the drone before feeding into the dot product

[runic terrace]

That looks correct, just normalize the velocity

[dry sleet]

Static meshes will be cheaper I'm pretty sure.

[lusty shard]

Alright, so I am getting decimal values from much more smaller ranges but not sure what I was expecting or how to use it. for example, the dot product is giving me this. IS it worth considering that the checkpoints arent in a straight line, also rotate to create a circuit.

all decimal values which is nice I think, compared to before where I had values ranging between 500 and -180 lol

[atomic salmon]

with normalized vectors the dot product will be between -1.0 and 1.0

assuming your gates' forward vector is along the direction you should cross them, a positive sign of the dot product means you went through them in the allowed direction

a negative sign means you want through them backward

[lusty shard]

so perfectly aligned drone and gate would have a dot produc of .00001?

[atomic salmon]

Nope, of 1.0

If the drone goes through along the exact forward direction of the gate, you will get 1.0

[lusty shard]

oooh nooo..

alright. so default forward for unreal is x correct?

[atomic salmon]

red vector (X)

[lusty shard]

so I have to rotate my gates by 90?

[atomic salmon]

Or use the right vector if they are already rotated that way

Means the allowed go through direction is the right vector (green axis)

the logic of the dot product stays the same

[dim agate]

https://blueprintue.com/blueprint/2v8ld5hg/ So this gives me a smooth camera transition in both directions.

Meanwhile this has the camera get stuck on the player head when going back to 3rd person from 1st

https://blueprintue.com/blueprint/k0yhjhmk/

[lusty shard]

this is awesome. I switched to right vector and getting -.98... haha but i see it! thanks a lot!

[dim agate]

Difference between the two is disable and enable input has been swapped for changes in mapping context.

[atomic salmon]

@lusty shardinvert the sign by multiplying the normalized velocity vector by -1.0

You will get 1.0 for the proper direction

[oak coral]

https://www.youtube.com/watch?v=14wmGdbhLOA&pp=ygUUdW5yZWFsIHNhdmUgYW5kIGxvYWQ%3D is there an efficient way to make a save and load system for every variable in every blueprint? The tutorial seems only tailored toward a few variables.

[lusty shard]

Thanks! instead of having more math nodes that might cause other teammates to scratch their heads, I will fix the gates rotation to use x as its forward axis.

[frosty heron]

No, you will have to be the one that decide what goes to your save file

[lusty hedge]

the print strings are firing but the setting doesnt happen

[dim agate]

Does the "trigger" setting for an input cause funky stuff when that same input is affected by a mapping context swap? I fixed my problem above simply by going from "triggered" to "started" because I noticed the flip-flop in the BP was firing off several times from one button press.

[lusty hedge]

when i get a function to print the key name it comes up as 'None'. it only works when i hit the interact key

[frosty heron]

Trigger runs every frame

[lusty hedge]

Before and after hitting F

[frosty heron]

Avoid cross pinning

[frosty heron]

It will give undesired result

[lusty hedge]

is that just a bug

[frosty heron]

This is a problem

No

[lofty rapids]

well when it runs it will try to get that key

[frosty heron]

U r not suppose to do that

[lusty hedge]

the first pin is from begin play

[lofty rapids]

use get

[frosty heron]

Again you can't cross pin like that

Get rid of the sequence that sets the variable

That's a no no

[lusty hedge]

does this still count

[frosty heron]

That set keys not gonna work or at least cursed

Yea it's still the same

[lusty hedge]

):

[lofty rapids]

what are you trying to set it to on begin play ?

[lusty hedge]

i want to set Interact key to, the interact key

so i can later display its name

right here

[lofty rapids]

you getting that key from an input event though

[lusty hedge]

but it comes up as None. up until i updated unreal by hitting the interact key

[lofty rapids]

so when you cross the wires like that it's not pulling the key because there is not one, the event has not fired yet

[lusty hedge]

i need to get the key from an input event

i want it to display what the player has binded their interact action to

[lofty rapids]

but your on begin play, that interact event has not fired yet

so i'm not sure what key your looking for

because that would be triggered most likely on a keypress or something

[lusty hedge]

i see

so it doesnt hold the data until its pressed

so how do i get the key information

[lofty rapids]

it's output from the event

use get, but at the beginning it will be empty

because there is not key that interacted

[lusty hedge]

then i have the same problem

the text will show as 'none' until the player hits the key first

[lofty rapids]

so don't show the text

[lusty hedge]

so dont make the feature im trying to make

surely theres a way

i need to show the text so the player knows how to pickup items

[lofty rapids]

i see what your saying

you define those keys

[lofty rapids]

you'll have to map some data to what your keys are

[lusty hedge]

i could i suppose but then the player cant bind their own controlls

[lofty rapids]

right i see the problem

[lusty hedge]

its tricky

maybe i can save them as text in the settings menu

before the game starts

[lofty rapids]

you could do that, and when they pick a new key save it

and just have defaults

[elder lodge]

I have this BTTask that I want to be able to accept either an actor or a vector
While this works just fine at Runtime, it blows up the log when the Key doesn't point to an Actor
Is there a cleaner way for me to organize this such that it doesn't attempt to access the Actor's location when it's null?

[dawn gazelle]

Check if the actor is valid and only proceed to execute if it is valid.

[elder lodge]

I guess then I'd have to just make a second line trace node for when it's a vector after a branch, which is what I considered but just seeing if there's any way to do it without repeating myself there.

[remote meteor]

Move the get location into a pure function, then resume as normal. Within the pure function, branch if actor valid, return accordingly.

[elder lodge]

perf

[royal vale]

Not sure exactly where to post this question. But my project has been built fully with BPs

my packaged game intermittently receives this error on startup after playing the game for a bit , closing the game and then opening it back up.
When the error pops up , it stops the game from being started.
Error: "Cannot Flush Async Loading while async loading is suspended".
The game uses save states , so I'm assuming the error is linked to that.

If i delete the save file , and reopen the game the error goes away.

Ive tried googling this error but not finding any luck , any one got any direction or advice on why this error is occurring? ty :0

[finite hearth]

I would appreciate some advice on how to improve my ai logic.

I am using DetourCrowdAIController and for the most part it works okay. The issue I have is when I assign three dudes to attack the same target actor; often one of my dudes will get stuck trying to path around the other dudes (see video).

I am thinking of writing some interface functions among my dudes and adding logic where dude A & B might make space for dude C; but I'm wondering if there is an easier or better way to improve pathing.

I am using the "Move to Location or Actor" with the target actor as the goal pin.

[edgy ingot]

Because there is no instance of it?

You have to construct them at run time then you can get a ref to it

Use construct object to make one

[trim matrix]

Oh, its an object ref

[crimson saddle]

does anyone know how to fix a blueprint with the error Overriden function is not compatible with the parent function <None> . Check flags: Exec, Final, Static.

nothing is being highlighted in the graph so I dont know what to do

[finite hearth]

check your object parent's graph/functions for conflicts

or its children

[crimson saddle]

its a problem with the child, but there is nothing highlighted in the graph

I think its being forced to implement and interface that should no longer exist

[kind estuary]

why do you say that the editor Struct variables get bugged/corrupted? I never had any issues with them... Though because i was told this, i try to create them in C++

[wanton prism]

i am having trouble making a puzzel where the player needs to switch / press certain things in order for it to work. I just dont know how to set them back to false if the player presses the first then third but it to not do that if only the player pressed first so ie its a puzzel where you need to click the correct ones in a certain sequence but dont return false if they have been pressed but they havent pressed another button.

Came up with this but i dont think it is efficent

[wanton prism]

Made a working version but its kinda bulky but allows me to use multiple?

[frosty heron]

Because they are broken and many people have become victim. My self included

Anyone that say otherwise just haven't step into the mine yet

[livid lichen]

Hi !
Atm i try to setup a behaviour tree for my enemy who should either try o chase me or get to a house destination which is lit on fire.

I set a bool variable called IsOnFire to true if my bullet overlaps with the house.
Now i go to the BehavourTreeTask and want to somehow get access to this variable to check which house is on fire.
I tried first to just Get Actor of Class of my BP_House but already there the value isn't set to true if I check it with the mousover the node even though in the debugger if I check on the variable the IsOnFire is set to true to one of the houses as it is supposed to be.
So i then thought it would makes sense to get all actors of my BP_House and then check with a For Each Loop if the IsOnFire value is true or false. But on this step I can't access the variable from the array element.

I tried to play arround with GameplayTags too but this didn't seemto work too.

Is there soemthing else I am missing or do I have to try another approach ?

[lunar sleet]

We have an #gameplay-ai channel btw. 4th pin video in there is very useful to learn how to use BTs. Using gameplay tags within a BT requires exposing IGameplayTagInterface to BP using cpp

[livid lichen]

Oh my bad should have taken the #gameplay-ai channel.
Since I just need to check on 1 thing gametags might be a bit more than needed anyways. I now even tried to check if my object has the tag I did add earlier today and it works like a charm now

[leaden helm]

any idea why my actor tag isnt getting set? or, doesnt seem to be?

[wraith loom]

Is there a way to "un-cast" things after I'm done with them? Because the description for casting in Unreal makes it sound like casted stuff stays in memory forever.

[leaden helm]

shouldnt stay in memory forever. should just be for standard variable lifecycle/GC afaik

[wraith loom]

what's GC?

[lyric basin]

just seeing this but you could make a function in which it sets whatever variables you want and then just call that function whenever you need them changed.

that way its a one and done kind of thing and makes your code look a lot neater.

[lyric basin]

It doesnt stay in memory forever. it just goes on the stacks, the call is processed, whatever values are returned are done and then the code moves on.

[lyric basin]

I cannot remember where I saw it, but in c++ you have the ability to take input from the user and assign it to variables. inside of the editor you have the option of changing the value of an input action key when it is selected on the right hand side in the details pane. I would imagine that it can be rigged up to take input from either a button press or a drop down or something and then assigning that to the action you want completed.

[paper smelt]

How do i apply dammage to my NPC it does not seem to be working

[silent stag]

Hey , i am trying to crouch smoothly here but it working only one time

[elder lodge]

Play From Start
Timeline does not reset unless you tell it to

[trim matrix]

then it will not be smooth lol

[wraith loom]

Does log string work in functions? For some reason I can only print to log from the event graph.

[silent stag]

It worked thank you so much

[frosty heron]

Crouching in multiplayer requires you to change the flag in cmc. You will need cpp for this.

Multicasting states for movement == ngmi

I just add interp values to the crouch anim to not make it snap

[silent stag]

What is flag in cmc

It's working properly without cpp now

[frosty heron]

U need to test with lag

Also on top of that, I don't think multicast belong here at all. Late joiners and players outside relevancy won't pick up on the changes

Same goes for sprinting, proning, etc. Should use the system like how they intent you to use it imo

[silent stag]

So i change that to on server right

[frosty heron]

For me there isn't an option but to dive to cpp for this case. You need to change the byte flags. Cmc already have the architecture, afaik u just need to override existing functions

Would recommend delgoodie video on cmc if you are interested

[silent stag]

I am not able to use c++ how can i test lag

[frosty heron]

Open console and type net.pktlag 150 something like that

Don't have editor on me

But add that and you will find out that bp multiplayer videos on YouTube are scams

[waxen jolt]

if this cast fails, will "Current Speaker" be set to null? The idea is to null check elsewhere through IsValid

[silent stag]

It's look fine for now

[frosty heron]

R u testing with server and client?

Server have 0 lag

[silent stag]

Is there any command to show lag

[frosty heron]

Not sure

[lunar sleet]

GC is garbage collection in this context. And ignore the description it’s just a heads up for people that make very big games with thousands of actors, but it scares rookies instead. casting is fine

[lunar sleet]

Not necessarily, it would be set to whatever ref is plugged in, could be a different object

If you want to force it to null on cast failed use another set with nothing plugged in

[waxen jolt]

that's unexpected but I suppose it's better to be explicit with my intent. Thanks!

[wanton prism]

yeah but also the code is kinda broken it only fires once if you get it correct i mean its only going to be used for that purpose i guess mission failed successfully?

[silent stag]

It's working fine both server and client but thanks for all advices anyway

[stoic nimbus]

Anybody know how to make a HUD only show up for a specific character? I have my HUD showing up for all my characters, but watned to give each a unique one? Any fix to this?

[frosty heron]

Need more info, show some picture

When I select the class I want, it applies the HUD to all characters.

[frosty heron]

U r not even adding any widget

Define everything, you are doing networked game?

Show a picture of the characters with the hud

[frosty heron]

Use the crouch function from character movement component. It will offset the mesh

[lunar musk]

I tried to use it, but i can't replicate

[frosty heron]

It's already replicated by default

Afaik

How do you use it? It should just be cmc-> crouch

And for your anim you can use cmc-> iscrouching to play the crouch anim

[boreal crypt]

I'm trying to use the control rig from within a blueprint of my actor. I have set it up, done the preinitialize mapping, and then in my event tick I am updating the transform of a control, but that appears to have no impact.

If I pull the value of the transform and log it (or render a debug sphere at that location) it is properly updating, but the mesh itself does not move/update.

I have tried setting the animation mode of the skeleton mesh to custom, to a blueprint that just evaluates the control rig and sends the result to the output pose, but it doesn't appear to update at all.

I am using the Control Rig Samples Pack from Epic, and just trying to modify the cannon_ctrl control in the mech to adjust where the turret is aiming.

I must be missing something, but the documentation doesn't really have anything, and pretty much all the guides/videos I can find, involve setting up variables on the control rig, and updating those in the anim graph, instead of directly manipulating the control rig controls in the actor blueprint using the control rig component. I want the latter, as I think it is much cleaner, but so far I've had no luck.

Any suggestions?

[silent stag]

You can use like this

[frosty heron]

If you are already in your character bp which has cmc then don't need to plug the target. Pretty sure that function will try to do what it needs to do to the cmc

[lunar musk]

Not working.

[frosty heron]

Define what's not working

[lunar musk]

My character not crouching

[frosty heron]

Print string the is crouching value

See if it changes when u crouch or uncrouch

U should show collision too

Check if u are actually crouching

[lunar musk]

Always false

[frosty heron]

Then Ur not crouching

[lunar musk]

Yep

I know

[frosty heron]

Print string after the crouch node see if u actually call it

[lunar musk]

Yep

It's called it

[frosty heron]

Don't have editor on me, can't debug more than this

Go to cmc and see if there is a bool cancrouch

If there is, tick it

Other than that I have no idea

[lunar musk]

You got it

Thx dude

[frosty heron]

Doesn't make sense to use static mesh for skinned assets. Are you making roblox? Just use leader pose comp imo

[frosty heron]

I would use leader Bose component for any clothing that goes on my character

[silent stag]

My character starting game with trying to turn right when i did not touch any input when i move forward it's turn back to normal. What could be cause that

[wanton prism]

it doesnt work trying to make it so if the player interacts they pick up the cube

[spark steppe]

pass the interacting entity (your player) as parameter of your interact interface function

and for grabbing something it needs to have physics enabled afaik

also you are using the wrong component for the grab component call i think

never used that node

but i guess it should be the static mesh component of the cube

Hi everyone, I have encountered a problem while making sliding doors. When the player walks into the trigger box while the door is moving, it interrupts the door's movement and it 'breaks' it. This is my blueprint for the sliding door. I was wondering if anyone could provide some guidance on this.

[versed sun]

[winter pebble]

I have an issue with some weird boolean behaviour where it's registering as true for the sake of gameplay logic but not for animation or when debugging it in my project. I wrote up a quite comprehensive post on the forums cause it was a bit long to put here but it's not had any traction, so hoping it's okay to post here in case anyone has any idea what's causing this: https://forums.unrealengine.com/t/character-not-entering-sliding-state-on-second-slide-after-a-jump-weird-boolean-behaviour/1624579

[forest crater]

Use lerp to update the location

[scarlet root]

Maybe one knows this.
The GetRandomReachablePointInRadius sometimes returns a Point, that is below the Ground or inside of an obstacle..

Currently, this is a flat plane... and some cubes..

so i currently tried to have a Loop that checks for the reachability of the Random Location, if false.. redo the code.. if true.. proceed to a spawn..

But still, sometimes, the Code spawns the item below the Ground or inside of a Cube...

Is there a better solution to make sure, the Player can reach the Item location?

[gusty portal]

anyone knows why the IA_Look logic is not working in my top down template?

[dire frost]

do you want us to take a guess...or are you gonna share some info so we can help

[forest crater]

You can just use a 1,1,1 vector and multiply the values by a random values in range -200 to 200 (1 to 200 for Z).
That way you will just pick a spot in a dome above ground

[scarlet root]

Yes.. but what makes sure, this location is reachable?

[forest crater]

Ah I understood it wrong, sorry, I thought you only have a problem with things spawning under ground.
Have you tried using the GetRandomPointInNavigableRadius node?

[scarlet root]

not available..
Maybe cause this function is not sitting in an AI Controlled Blueprint.. but in the PlayerController

[gusty portal]

what info do you need?

i copy pasted everything from other template which is used to rotate the camera

[scarlet root]

More than just "Why is it not working"
Like.. your code..

[gusty portal]

yet the viewport in this top down template just doesn't go into focus(i guess input only mode as it's known)

[forest crater]

Hold on I might be trolling

[dim agate]

Is this in your character or controller BP?

[gusty portal]

character

controller only has imc setup

[dim agate]

Does your camera have pawn control rotation enabled?

Or does the spring arm have it enabled?

[gusty portal]

no and no

ok i enabled it in spring arm

but it's still weird because it's only taking it when i click it

why doesn't the game view go into auto focus?

[dim agate]

What do you mean by auto focus?

[dim agate]

Add to the begin play event a set node for "show mouse cursor" and set it to false.

[gusty portal]

like my mouse is always visible in this project unlike in other templates where mouse disappears

[forest crater]

Weird, idk then.
There might be a better solution for it, but you can also check for overlap with objects before spawning, and
cast a ray up and check for whatever you're using as ground, and just shift the spawn point up above it if it's detected.

[dim agate]

The "set show cursor" to false should be in the controller BP that controls your pawn @gusty portal

[scarlet root]

hmm.. maybe i need to learn some EQS to get this working right..

Even with try Adjust location, it spawns underground or withing walls..

[gusty portal]

but in the other templates there was no such thing

[dim agate]

I know, but try this and see if it fixes your problem.

[gusty portal]

it works now

[dim agate]

I can't check now but it might be a project setting you can alter instead of telling the game to do it through BPs.

[scarlet root]

Seems like a good start...

[gusty portal]

ok can i somehow lock this rotation to only limit it in a circle around the player(no rotation on y axis)

(or x i guess only z rotation)

ok never mind

thank you

[dim agate]

Remove the add controller pitch.

[gusty portal]

i got it

[dim agate]

No problem.

How do I go about storing arrays of arrays in Unreal? I'm heard people say to make an array of structures with arrays in the structures, but I don't know how to do that. Also, if I do it that way, will the entire array be loaded into memory if I just want something from a sub-array?

[frosty heron]

Do exactly that. An array struct that contain arrays.

Wdym by loaded into memory with your context?, if you are talking about object ref they will be created on runtime so it will always be loaded to memory anyway

If you want to store hard references like static mesh, skeletal mesh etc. If you don't want them to be loaded to memory, you must use soft object ref

[remote meteor]

why are you new

[marble tusk]

If you do go with putting arrays inside a struct and making an array out of that, then it's worth mentioning that the default ForEachLoop macro gets a copy for the array element. You need a ref to the array of structs in order to set stuff in the arrays inside the structs. I've actually made my own ForEachLoop variants which get by ref instead of copy for stuff like this

[remote meteor]

There are many instances where you would want to use "ForEachLoop-byRef", you can make your own copy by duplicating the engine's and changing the Get(by Copy) node to Get(by Ref)

[young meteor]

Anyone have any guess as to why I get wrong viewport size with the "Get Viewport Size" node?

[remote meteor]

any chance your windows scaling is not 100%?

[marble tusk]

Yeah, there's also a few other things you can modify to make ForEachLoops faster, like storing the array length as a local variable instead of calling it every loop. Also making a version which saves a copy of the array as a local variable for cases where you'd be plugging pure nodes into it

[young meteor]

Is that in project settings? Or where do I find that?

[remote meteor]

your windows display setting

[pallid mauve]

I am trying to set up a very basic UI blueprint, where when the user clicks a button on the UI, the view changes to match the camera actor associated to the button clicked. I have set up a number of camera actors in the level already, but cannot figure out how to link the cameras to the blueprint. In the HUDRev screenshot the camera actor references actually do work as desired, but I cant save because 'HUD.uasset: Graph is linked to object (ObjectRef) in external map' .

[young meteor]

Seems like a 100% like you.

[remote meteor]

is it on PIE?

[remote meteor]

if so then the Viewport Size is actually Resolution * Viewport Scale

and Get Mouse Position on Viewport is getting it relative to just the Resolution

so you might want to do some scaling before comparing them

[young meteor]

Just tried in standalone game and function actually worked there.

Surprised by that since it did not work when I packed it to a "shipped" game.

[heady burrow]

do I get line plane intersections if I set the planes to be hidden in game?

[young meteor]

Thank you for your tip. Dividing by scale seems to work. Both prints cap at 1080 which is what I wanted.
Assuming that is what you wanted me to do. 🙏

Hi I have what should be simple but have been banging my head against the wall for a few hours now. I have tried lots of different options but nothing works. I am possesing a vehicle in first person view. I want to be able to look freely around like you can in real life but clamped to certain pitch and yaw relative to the front of the vehicle. Right now if I look at one point and steer the car in a circle my point remains the same. Any Ideas?

For example I want to look out to the left window but if I turn the car to the right I Want the camera dragged along. Not for the players neck to break lol

[wraith loom]

I tried making this, but I think "array element" on the output should have a diamond instead of a circle connection point. How do I do that?

[tidal marlin]

Hy. Does anyone have problems that when you put Game State in Gamemode, the game stops completely?
I already know how to solve it, I'm interested in why?

[alpine plover]

Hey everyone! First thanks for reading my post and I hope you have a great day! I'm not new to the engine but am still new to blueprinting so maybe one of you can help me out here. Right now I'm getting actor bounds of my canvas actor then finding a random point in the bounding box. I'm wanting to add a certain number of points to an array of transforms to hold the transform information BUT I want the random point to only go into the array if it's at least a certain distance away from all other points and I'm struggling with figuring that out.

Right now to make it easier to visualize I'm spawning an actor with just a billboard image so I can see it and the only way I've been able to figure it out is to find 200 points (to visualize it spawn 200 actors) then delete actors that are to close to one another but that doesn't seem very efficient.

The purple box in the first image is where the second image is. If you have any ideas or if I'm doing this all wrong and there's a better way I would very much appreciate it. Right now I'm running into issues where there are times that all of my landscape stamps are clumping together and that just doesn't look very realistic haha. Thanks again

[marble tusk]

I don't think that matters as a macro (macros act like you're just pasting all those nodes in the graph you place it in), but also I've noticed inconsistencies here and there with pins which are still being passed by ref having a circle pin

[wraith loom]

oh okay

[marble tusk]

One example is using break nodes for structs. Those I think always seem to have circle pins, but if it's not a copy being plugged into them, then they still are by ref.

[marble tusk]

Actually, try going to File -> Refresh All nodes. That might fix the pin. I'm looking at mine and it has the diamond pin. I think it's just a visual thing though

[wraith loom]

I refreshed the nodes and restarted the editor and it's still a circle

[marble tusk]

I don't think it will effect how it works, but if you really want it to be a diamond you could probably drag off the GET node's diamond pin and drag it onto the output node. That should create a new pin with a diamond pin

[wraith loom]

Ah that worked, thanks.

[marble tusk]

Also, something good to know is that while this works for Macros, Functions on the other hand can't have outputs by ref

[wraith loom]

OK. BTW is there a way to make a macro available to use with other assets?

[marble tusk]

You can make a blueprint macro library asset

[wraith loom]

okay

[marble tusk]

I think the default ForEachLoop is in one as well, but you probably don't want to edit that one

[wraith loom]

Yeah I tried searching for the Standard macro library in the content browser and couldn't find it

[lofty rapids]

double click foreach

[marble tusk]

Oh yeah, to make one you can right click Content Browser -> Blueprint (the folder one under create advanced asset) -> Blueprint Macro Library

[wraith loom]

I think you told me that already

but thanks

[marble tusk]

Just making sure where it was. At first I checked by just trying to make a blueprint class, but it's its own special menu option

[boreal crypt]

Still struggling to get my control rig to actually update from a blueprint when calling SetControlTransform, in debugging in the control rig window I do see the control as moved, but the rest of the rig does not update, so now I'm really confused.
Attached is what my blueprint currently looks like, and in my EventTick if I render a debug sphere at the control transform location, it renders properly, but the rig will not update.

Also attached is the animation blueprint, which at the moment just executes the control rig and passes that to the output pose

I'm just completely at a loss as to why it will not update during play. If i drag the control around in the control rig editor, everything works. This is a procedural generated rig from the epic games sample control rigs pack (the mech),

Can I update the controls in the rig in this manner? Documentation seems to show so, but I don't see any examples calling Set Control Transform, and pretty much everything I see updates the rig itself to not use a control, but use a variable to adjust locations and such,

Add an event dispatcher that you call when the button is clicked. You can then bind to that event dispatcher in anything that has a reference to that widget.

In my parent ?

Ohh okay thanks i see !

I'm looking for "orbit" an actor around another with blueprint

[hollow cove]

how can i get the bounds of a landscape, always returns zero

[hollow cove]

https://math.stackexchange.com/questions/260096/find-the-coordinates-of-a-point-on-a-circle

use this math and move the actor on tick around the circle by increasing the angle each tick

[lyric basin]

I got a system I can share. one minute

[odd kiln]

I thought I should use the "Rotate Vector Around Axis" node maybe ?

[lyric basin]

possibly

my system uses math. sins and cosines and then updates the actor location in real time. doesnt run on event tick

I will share a video one sec

[odd kiln]

Oh ok great thank you, if I don't have to use th event tick it's better I guess

[hollow cove]

how do you update the actor in real time without using event tick 🤨

[odd kiln]

maybe with an event loop or timeline loop ?

Hi guys. I can't find any info, how to do it cleaner.
I tried to use Set Animation Current Time, but as function description says it don't change state.
Any ideas?
I just wan't widget be in end animation state

[hollow cove]

are you adding the directional vector youre multiplying to the original vector

[keen ore]

Could pls clarify what you mean?

[lyric basin]

timeline loops

its for my planet system

[hollow cove]

you have location say 100, 100, 100. you have a directional vector which equals one, say 0.5, 0.5, 0. you're multiplying the direction by 100 to make it 100 units in that direction, so 50, 50, 0. if you have the start at 100, 100, 100 and the end at 50, 50, 0 its not going to point from the location in the direction itll point to where that direction is in relation to zero, so you add 50, 50, 0 to 100, 100, 100 so the end is 150, 150, 100

the direction would be the forward vector from the camera here

[hollow cove]

i mean that works but it depends what resolution you need the movement to be at, if its an actor you're close to instead of a slowly moving planet it makes sense to do it on tick

anyone have a solution to getting the bounds of the landscape?

[odd kiln]

Did you try to use the "GetActorBounds" node ?

[lyric basin]

this is what i meant

[hollow cove]

yeah, it returns zero. tried doing component as well

[odd kiln]

That's exactly what I want but on the Z axis

[lyric basin]

yeah I can change it so it moves around whatever axis I want.

I looked up orbiting planets and found something that worked

[odd kiln]

And with the same distance between the 2 actors if possible

[odd kiln]

Do you use "Rotate Vector Around Axis" node ?

[lyric basin]

nope

[supple dome]

do you have C++ in your project? theres some functions GetLoadedBounds and GetCompleteBounds in c++
you can create a BP node with
return InLandscape->GetLoadedBounds()

[lyric basin]

two timelines, two set actor locations, and a good number of math expression nodes

[odd kiln]

Why two timelines ? For each axis ? X and Y ?

[lyric basin]

no, one just loops the location of the actor and the other loops the rotation to keep it in the same pitch

[hollow cove]

only using blueprints right now. is there no way to get landscape bounds outside of c++

[supple dome]

those two functions doesn't seem to be exposed

only if theres another way

[hollow cove]

looked at get complete bounds and it returns the bounds of landscape proxy, so i did this and it worked

[paper gate]

what is Data is ?? which data type is this ?

[lyric basin]

Is your socket name correct? It is case sensitive and it needs to be attached to a socket, not a bone

[odd kiln]

Ok I guess I got it but I don't know why when my actors are far from each other the orbit speed is not the same as if they are close

[lyric basin]

can you share a video?

[lyric basin]

if you are using the same logic for both actors, then their speeds and positions in orbit should be the same, provided they fired off at the same time

[lofty rapids]

you can check if the event is actually being triggered with a print string, but it looks like your trying to pull from a place that is running on a different event.

[olive yarrow]

ugh, good call.
on a side note, if i completely remove the whole widget and just have the collision event start dialogue - it works. Is this due to the isPressed being called from a different event? (if that's what you mean, sorry )

[dry sleet]

It's an array of some struct

If you want to see what, you can pull out from the Data pin and select "Make Array" to create a node which has a single instance of that struct

Then you can pull from that and select "Make XXX" (where XXX will be the name of the struct in question)

I do believe you have responded to the wrong person

[olive yarrow]

i love this place

[lofty rapids]

the circled part is data that your creating on a different event. Most likely you don't want to keep creating the widget but just display/hide it ? In which case you would have a reference to it that you can use if that event is firing.

[dry sleet]

It's generally not a good idea to pull data directly from nodes (other than variable getters) in different events.

[olive yarrow]

You are correct - show and hide when capsules overlap!
when you say reference, you mean one stemming directly from my sets as the target? and referencing my widget yeah?

[lofty rapids]

reference the widget, create the widget somewhere and promote to variable, then you can access the reference instead of pulling from another event lik that

similar to the other one you are remove from parent

it's a reference i think

[olive yarrow]

i believe you are correct, just made a variable for wb_interact, i''ll plug it into the booleans and see!

OH! Should i ahve my ia_interact be casting to my playerBP? 😂

no no it got angry.. hmmm... still not firing (or at least no print string is happnin'

[lofty rapids]

so you put a print string on the interact even and it's not showing ?

how did you do your context ?

[olive yarrow]

I'm assuming it's from my interact action... maybe it's not registering whether or not it's my player pressing E?

But i struggle with how to use the interface so i can send the message at all to another blueprint WITHOUT any previous actor reference? Can anybody help?

so in short the event cant fire because i have no target for item equip hat (message), and i want my target to be the blueprint actor.So how can i choose a blueprint as target?

[olive yarrow]

have you attempted either a variable for the playerBP to plug into the target, or to reference your character? (this sounds right in my head but i'm not too hot at this yet)

How do i comibne these two animation

I figure out

thanj you

your still creating one, probably want to use the same reference. But if your print string isn't showing then something is wrong the event isn't firing

I'm having a couple issues though. 1. some times the blood decal spawns on the enemy. 2. most of the time it's not spawning decals at all, even when the niagara system occured. I've supplied my bp, but I actually am curious if this is possibly a problem with the physics asset? maybe it needs adjusting to be more accurate? https://blueprintue.com/blueprint/4ie02ev3/

may be obvious but if i put IA interact intro my playerBP it works, just ... not in the person i'm tryna start my dialogue with

Any of the "Get All Actor" nodes are slow so it's best to only use them once such as on Event Begin play as long as the blueprint actor you're using it with isn't going to be spawned in multiple times. So for example its okay to use this on something level placed like a door or a car, but bad to use it on something that might keep spawning and then getting destroyed such as a cannon ball. Also never run that node on tick. The slowness of the Get All Actor nodes depends on how many actors you have in your level, so as your level grows in complexity those nodes have to search through more and more actors looking for the specific ones which match.

[olive yarrow]

wait nvm, only if the characters touch does this happen after removing the link from remove from parent to closegate

@lofty rapids check it playa, technically works... but i just need a way to check which dialogue to start in relation to the NPC.... not in relation to my variable...

[cyan spire]

Thank you, and what about the "Get Actor of Class" node which is more specific?

[faint pasture]

that gets 1 actor

the other one gets all of that class

[broken wadi]

It still has to search through the entire level of actors for that particular actor.

[odd kiln]

Finally I used the "Rotate Vector Around Axis" and I multiply the "Tick" by a variable and set it to the "Angle" pin of the node to set the speed of the rotation

The problem is that when the distance between the 2 actors change the speed changes too

Anyone knows why ?

[cyan spire]

So how am i exactly making a reference properly to the BP i want to send the message to?

[broken wadi]

If both actors are already in the level you can just make the variable public instead of private then just select it using the eye dropper.

Heyo, I have a question for anyone who has worked with PCG. I see that Static Meshes can be generated (via Static Mesh Spawner) via attribute (full path provided). But I don't see a way to spawn an Actor (via Spawn Actor node) in the same way. Has anyone messed with this? I'm currently digging around the source code, but that's not been going too well. I've been rummaging around online as well, but only ever see mention of Static Mesh Spawners doing this.

Any help would be greatly appreciated. Thanks

Or maybe an alternative, is there a good way to spawn an Actor into PCG and merge it manually into PCG. At this point I'll take either. I just need this item to be 'cleaned up' with the pcg via the "Clean Up" button (and by spawn Actor, I mean via a blueprint and Spawn Actor From Class node)

[cyan spire]

They are not in the level currently, and it doesnt let me

greyed out

[broken wadi]

If both actor A and actor B are in the level and you need to make a reference to actor B from actor A. You can select it using that tool you have in the screenshot.

[broken wadi]

There's no incoming connection for that pin

What are you trying to setup?

[cyan spire]

Just firing an event in another blueprint. So i have Blueprint A (Class Character) and Blueprint B (Class Actor). And i want to figure out how to fire off an event in blueprint B when i press T with its logic in Blueprint A. But i also need to pass through the mesh variable. So im using the interface for that. But the main problem is as you know the performance is bad with Get Actor of class. So i want to make a reference to the blueprint i want to send my message to

[broken wadi]

If the blueprint B is level placed such as a door or something, then you can just use Get Actor of class during the begin play of the character since its loading everything else during that time anyways. It's only bad to use that node frequently.

[cyan spire]

Yeah but there must be another way right? A more performance oriented way

[broken wadi]

But it won't make a difference because that's when loading occurs, at the beginning right?

[cyan spire]

I just need to find a way to "mark" that 2nd blueprint as my reference and pass THAT reference into the first blueprint

yes

this is pretty much whats happening in the 2nd blueprint

[broken wadi]

Plus you can use something like a Do Once node so it only makes the reference to blueprint B once during character on begin play. So if your character dies or something and you need to "restart the level" you can just teleport them back instead of destroying the actor and spawning in a new one then posessing again.

Oh so you're doing a line trace whenever you press T?

[gritty palm]

Hi

Where can I find a tutorial tovmake Match 3(like candy crush) game using blueprints?

I did aome google search and only found some old UE material

[broken wadi]

then just call the interface event on whatever actor was hit, that's the beauty of interfaces they are fire and forget you don't need to worry if the hit actor implements the interface or not

[cyan spire]

I know, i got it already working this way with a linetrace, but i removed the trace now to see if its also possible to do somehow without feeding in the hit actor, so just purely by class

[broken wadi]

Oh okay then you just need to use a reference. You can either use Get All Actors of class during event begin play of your character or if both the character and the actor you need a reference to are level placed meaning they are not spawned in during runtime then you can just use a public variable as the reference and use the selector tool to assign it.

[cyan spire]

how am i supposed to get that variable in the 2nd picture?

Just did what you said, set public and set default value, but cant see it in the context menu

[broken wadi]

If you want to press T so that a character can open a door. You make the door reference public and have it live inside of the character blueprint.

Then you just call the open door event via the referenced actor when you press T. There is no need for an interface.

[regal igloo]

Can someone help me. I am getting this error and not to sure why

Invalid property 'L_Mission1SoftRef' class, replaced with Object. Please fix or remove.

I did change the variable's type. after deleting the original type first.

But when fixing the errors i changed the type from object to new type which is base mission actor and now i am getting this error.

any ideas?

[broken wadi]

I think what's confused you is that you started working towards a solution using one approach then you asked for help with a different approach and are dealing with blueprint that's sort of halfway between both solutions.

[olive yarrow]

i am progressless on this interaction shtick

[broken wadi]

The easiest way to do basic interaction originating from input key press via a character is to perform a line trace then call an interface event on the hit actor. Then on your actor which you want something to happen when the character interacts with it you must implement the interface event then have it run whatever logic you want to happen. This way you don't care if your character's line trace hits an actor that doesn't have the interface at all because nothing will happen.

[olive yarrow]

I believe i'm pickin' up what you're putting down. I believe....

[olive yarrow]

can i keep buggin' you for further brainstorming?

[broken wadi]

Just ask in the channel and someone might read it and answer

[olive yarrow]

yeah fair nuff 😂

What exactly is calling an interface event on the hit actor in my player actor? I've done line traces before in Gorka's tut but i've been staring at a screen near 10 hours and can't giive up till at least this part's done

[wraith loom]

I'm following a tutorial and the custom function made by the guy in the video is green, while my function is blue and has a target input. Why?

[olive yarrow]

Do you have multiple Array Index choices when you begin searching?

one looks like a "set" and one looks like a "get". probably better word usage but that's all i got

[wraith loom]

No there's only one option

[olive yarrow]

hmmm.... look i'm not great but dammit i'ma try and help. Have you tried coming off a green node and entering what you're looking for?

[wraith loom]

just tried, still the same

[olive yarrow]

mind sharing the tut? Lord knows i could use a break from my junk

[wraith loom]

It's fine man I can wait and see if someone else knows

thanks for trying to help

[olive yarrow]

us rookies gotta stick together

or atleast i'ma rookie

[wraith loom]

I am too

[frosty heron]

One is a pure function

The green one that is. It doesn't have execution pin

[wraith loom]

ah okay thanks

[elder lodge]

right click to convert a function to a pure function

er, wait, no, it's a bool in the details panel

one of those, maybe circumstantial

[olive yarrow]

my uh.... target for interact is yellow. why no blue?

[elder lodge]

What's the variable type you set for the function?

it says "Target is BPI Interact"

[olive yarrow]

errrr? i'm following this D':

[elder lodge]

did you make the interact event/function? where did you define its inputs?

[olive yarrow]

I did! I have no in or out like in the tut

fudge wrong one

still no dice however

[frosty heron]

U r not pulling the right node

U want the one with the msg icon at the top right of the node

[olive yarrow]

Sorry?

https://www.youtube.com/watch?v=xAsOFNdO7E8 this is what i'm following, they don't have the issue

https://www.youtube.com/watch?v=veIJ5tfoUB0 ok ok this seems to have helped

[steady light]

Hi all, I've been doing some reasearch and troubleshooting and cant seem to find an aswer to this. Im currently live streaming weather into my environment through an api request. When I get the data it comes lowercase like "broken clouds, shower drizzle, clear sky"

I would like to find a way to set the text received as Title case. But I've just hit a dead end. One solution I thought about was just having a Branch for every possibility then if the string matches to manually set the text. This isn't ideal considering there are about 50 possibilities. Any suggestions/help is much appreciated!

[broken wadi]

https://docs.unrealengine.com/5.3/en-US/BlueprintAPI/Utilities/Text/TexttoUpper/ might be that one, but then again I dunno that might be all uppercase?

[celest trench]

Is it possible to get the name of a variable in blueprint? For example if an int variable is named BedroomCount, can I get the name instead of the value? Strange thing lol

[steady light]

Hey @broken wadi , thanks for the reply! Yeah, unfortunately its all uppercase when I tried that method

[olive yarrow]

now my character just floats wtf

and now the game crashes if i try and test

wow

what a day

[gritty palm]

Hi

Where can I find a tutorial tovmake Match 3(like candy crush) game using blueprints?

I did aome google search and only found some old UE material

[hardy swallow]

There is an official match 3 game made in UE4. That should give you all the logic you need, and you could probably recreate it using that reference.

[hardy swallow]

Pretty sure the Rama Victory plugin has what you need, and if not, this is great first C++ project

[hardy swallow]

You'll have to cut off the front, but this is one way of doing it

[edgy ingot]

You can break it down to individual char and only upper the first one and the char after space

This can easily be done with some formatting text logic

I suggest to look at sub strings and other format function available to you

[lyric basin]

what is the exact error you are getting? you can probably salvage the game, might just need to rebuild

[olive yarrow]

Salvaged, but now having untold errors with my Not Yet dialogue plug in 🙄 set back after set back today my friend

[lyric basin]

start at the beginning. are the errors on project load or when you try to run in editor?

[olive yarrow]

now, thankfully, my errors are more or less gone - it's only now while IN editor and attempting to begin dialogue

[lyric basin]

what you are looking to do is pretty UI intensive, I would suggest looking up tuts on widgets and the On 'whatever function happens' buttons that go with different buttons.

[lyric basin]

okay, whats the error. might be able to help you

[olive yarrow]

More so an array issue, my Start Dialogue has different variables than in the tutorial. Earlier i could get dialogue to start, but then i tried to make it start via line trace and oh man you've missed alot

need this

have this

[lyric basin]

the first one is a custom event inside of Third Person Character. The second is a function of the same name

Are they both inside of TPC?

[olive yarrow]

oh my god.

one IS a function

[lyric basin]

yup yup
