blueprint

[celest salmon]

Hey, I don't want to interrupt-- but I just wanted to ask for some help with making a 1 hour day and night cycle.

[exotic cradle]

Go onto youtube and lookup Ue4 day and night cycles. There are quite a few tutorials I myself followed and actually combined a few methods to make my days and nights how I wanted them, darker nights and prettier days!

[celest salmon]

Oh, I did-- but most of the ones I could find took about a minute to finish.

(As in for the day and night cycle to finish and start it's cycle again.)

[exotic cradle]

Send pic of BP

Im pretty sure you can adjust it accordingly

[unique harness]

And all you need to do is call AttachToActor and keep world transform

[celest salmon]

Well, most of the tutorials use this from the old ue4 wikia.

https://nerivec.github.io/old-ue4-wiki/pages/tutorial-time-of-day.html

The sun is moving way too fast!
The sun's speed is controlled by the "SunSpeed" variable in the blueprint you set up. Whatever value this is set to is how many degrees the sun will rotate in one second. For instance, if you have this set to 90, it will take 4 seconds to go through one day. Just reduce this value to slow it down.

I found this here, but when I did it, it didn't seem to work.

[exotic cradle]

ig Im not understanding. I just tried that it and it actually deleted the item and make this wierd movment with my pawn

[unique harness]

So if you have two objects on the screen and you click near one, what is supposed to happen?

[exotic cradle]

Ohh okay that was my bad from the beginning. Okay so when this level is opened a single object is spawned in the middle of the box collision that you need outlined in the gif I sent. What Im trying to do is take an item that I have selected on my hotbar, which I have working, and have that item attached to the other item I click on with my mouse. I have 6 sockets on each mesh since they are cubed.

[unique harness]

ok so in the gif, what is wrong?

it's just not actually attaching?

[exotic cradle]

Yes.

[unique harness]

ok is the spawned thing just going to be a mesh or is going to have logic tied to it?

[exotic cradle]

It will require some logic so it knows whether a socket is occupied or not so it can give the go ahead to attach if unoccupied

Ima save that question for after my first one gets answered lol

[unique harness]

i'm talking about the object you're spawning

you probably need logic so

the root of the object you're spawning needs to be at one of the socket locations

spawn the actor at the socket location

then call AttachToActor and specify the socket name and positioning parameters

store an array of 6 booleans, false means available, true means something is attached

every object after the first should have the root socket set to true in the array

[exotic cradle]

Okay. So what Ima do is within each child BP I have for the objects I am going to make logic for the sockets and see if I can get it to work from there.

[outer lance]

So I have a construction script in a placed blueprint, and wish to get debug info from it.. print string doesn't work :S What to do..

Hmm to answer my question I could f.ex. make a visible array of strings and add to it..

[tight schooner]

Have the construction script add a text render component? I do that sometimes

[unique harness]

there's a class setting to run construction script each time you compile, could try that

[paper python]

Hi guys! Sorry to bother with something probably simple, but I've been struggling for 5 hours with it now, to no avail.
If I have an object A (person), an object B (cat), and a vector offset that says where the cat should be (like, 2m behind and 1m to the left of the person).
What should I do with that vector offset? so it becomes relative to the direction of the person (always spawns behind the back, no matter where the person is looking).

[split ginkgo]

Something is moving my player up by 19 units, is there some way I could watch anything thats changing my players location and trace it back to the blueprint node, or at least the blueprint actor thats doing it

[dawn gazelle]

Something like this?
https://www.youtube.com/watch?v=13YlEPwOfmk

[unique harness]

@paper python just add a scene component to your actor and use that to set the cat's position

[paper python]

I just picked human/cat randomly, it's really about two separate objects in space.
Actually it's about hundred objects moving in relation to one leading object, but let's keep it simple.

[unique harness]

are the following objects at a static offset or slight variability?

if static, my previous statement still stands

[split ginkgo]

@paper python Idk if this will actually work, but you could invert the forward vector of the person, and use that to place the actor behind the person. The math will be like this: PersonLocation + (ForwardVector * 100)

100 is the amount of units that the cat will be placed behind the person

[maiden wadi]

Alternatively, just transform it with the main actor's transform.

[split ginkgo]

You would probably want that to be smaller than 100 though

[unique harness]

that would place it 100 units in front of the person, not behind

[split ginkgo]

Oops

You would have to invert the forward vector first

[unique harness]

or just subtract it

[split ginkgo]

I think you could probably just rotate it 180degrees

But theres probably a better way to invert it lol

[unique harness]

but still the more simple solution is using a scene component to mark your target location and do whatever interpolation to that position

[split ginkgo]

Yeah

But I feel like thats clunky

[paper python]

Hmm, not sure? It's a unit formation.
Each unit (small dots) can know its relative offset from the center point. Or it can know its vector from center point. Whichever works, I can calculate it when spawning them, store it for later use, etc.

But I cannot understand how to make them spawn if the Center Point is rotated.

[split ginkgo]

I don't really like to add components that could just be replaced by some simple math

[maiden wadi]

@paper python

[unique harness]

the scene components are always relative to the actor's rotation

can make some simple constructor variables to define number of rows, columns, and x/y offset

[paper python]

So.. ForwardVector * offsetVector? Damn I hope that works (I'll also hate myself for a week if it's that simple :D)

[maiden wadi]

The issue with components, is that they need updated every single frame if they're moving. This is fine with a few things or things that move very rarely, but if you use this method on hundreds of things, that gets very expensive to have a bunch of scene components being updated just for local space positioning.

[split ginkgo]

@paper python Make sure to rotate the forward vector so its actually facing behind you

[unique harness]

you would still have to do the same thing for the actors themselves when moving

[split ginkgo]

If you don't then the cat will be in front of you

[maiden wadi]

Simple Vector math is a lot cheaper than component movement.

[split ginkgo]

Yeah

Its also just cleaner

Less components on the player

[maiden wadi]

Like I said, not an issue with only a few things, but it's something to keep in mind if you have a lot of scene components on a lot of things in your game. This is why if you can put it in a normal actor component and use vector math relative to the owning actor, it's a lot cheaper.

[unique harness]

my point is that the math will have to be done eventually. rather make the components and attach the actors instead of computing the vector math yourself and then moving the actors yourself

[paper python]

Phew. ForwardVector works. I will hate myself for 3.5 days, because I actually tried that just before writing to the channel... but I used the BP node that just gives 0.0.1 instead of Actor's forward vector.
Before that, I tried all sort of things to do with triangles and circles and radius etc.
Bless you, guys, for restoring my sanity 🙏

[split ginkgo]

lol, np

I'm glad it works

[maiden wadi]

It's not just about the math. You have to factor in all of the calls and updates happening when a component is moved. Each and every component does this when you move an actor.

[stray island]

I have a hierarchical static meshes , is there a way to control instances meshes color say they range in three colors (array)

[unique harness]

which whether you have scene components or not, still has to happen to the attached actors

[maiden wadi]

You can see the issue if you profile a project with a few hundred AI moving, with a few extra scene components in them vs not having the components.

[unique harness]

We're not talking about AI, we're talking about having actors attached at an offset

[maiden wadi]

Then don't use AI, use simple actors that are simply moving constantly. Same thing.

[exotic cradle]

Whoops sorry replied to the wrong answer. My bad.How would I go about changing the 1 specific boolean related to the socket in the array of "isSocketOccupied?" booleans? Would I simply take the integer from the designated socket and remove it from the index?

[unique harness]

you're not removing it, just changing the value

whatever index you assign to that socket, that's the index in the array

but starting at 0 instead of 1

so if something is attached to socket 2, availableSockets[1] = false

[exotic cradle]

https://gyazo.com/29ea23411b1189ce48e1d6226dd7bd56?token=3f7df7564b59c3f32b976934b83107a9 Upon initial spawn.

[unique harness]

you probably don't need the is socket occupied variable

you need a set node off the array, not add

and no for loop, just assigning index 0 to true

then probably a method that says like AttachActorToSocket(AActor* ActorToAttach, int SocketIndex)

check the socket array to make sure it's available, if so attach it and set that index to true since it's now in use

[exotic cradle]

Would you be able to work up a quick example of your text? Im having a hard time understanding

[unique harness]

maybe, we'll see if the engine will open

[exotic cradle]

Yeah mines been acting wierd today and a few times froze at 75%

[unique harness]

I haven't had the editor open in like a year lol

[exotic cradle]

Oh jeeez lmao

[unique harness]

Don't deal with it in my new job 😦

[exotic cradle]

Luckily for you xD

[unique harness]

we should be converting our main product to UE this year tho which was basically the whole reason I was hired lol

[exotic cradle]

Thats always good lol

[unique harness]

@exotic cradle

Then in the child,

[exotic cradle]

Definitely was overthinking it lol

[unique harness]

😛

Place the master in the scene, only spawn the child and it should go pretty smooth

So when you spawn the child, you would call AttachActorToSocket on the the object in the scene

[exotic cradle]

So what happens if I delete the master item that is initially spawned when the level loads?

[unique harness]

You probably want a DetachMethod as well

and to store the attached actors

so you can detach them when the actor is deleted

so you could actually replace the AvailableSockets array with an AttachedActors array

[exotic cradle]

So say if I were to place 15 of them. Go to the first one that is initially spawned and remove it wouldn’t that cause issues with the other actors being a child of that initial object?

[unique harness]

AttachParent and AttachSocket are now expose on spawn

[exotic cradle]

Hmm. I dont have all of those Sockets as components for any of my bps

[unique harness]

Those are just place holders for how I added the socket locations

But that should give you a decent starting point to manipulate it to suit your needs

[exotic cradle]

Thank you for the help it is much appreciated

[exotic cradle]

Is that two different processes to doing it or one?

[neon sorrel]

Anyone know the best way I can disable a players input for x ammount of hours, even if they close the game? Any way I can use utc time or something?

[maiden wadi]

@neon sorrel What is this for? Like multiplayer punishment, or?

[neon sorrel]

A report system im using that sends reports / bugs to a discord server. Trying to just prevent users from spamming it

[maiden wadi]

I imagine for simple bug reports, you could possibly just utilize local savegame info to see the last time the player reported via UTC and lock it until then. Of course that's easily gotten around by just deleting the savegame which anyone that wants to be annoying will do. The only secure way might be some form of online check that can hold that, rather than someone's local data.

[neon sorrel]

Yeah, I mean I use dyanmodb already for player info and can use that. Just then it increases my traffic through the server and costs. so hmm

[vast lion]

Users can now access Control Rig data from Blueprints with the Control Rig Component. This enables users to drive Control Rigs with Gameplay logic in Blueprints, re-initialize Control Rigs to fit differently proportioned characters, and read or write other Control Rig data directly. ***Additionally, users can now attach non-skeletal mesh objects to the Control Rig hierarchy with accessors in the Control Rig Component.***

Anyone know how to do that last bit?

[robust jacinth]

Thinking of doing a "pipe mania" type puzzle for the mini jam over at itch.io. How would I store the game state in blue print? Is this a bad idea? Would C++ be the preferred way of doing it?

A big array would be a start I guess, but then I need to store the orientation of all the pieces, and check to see if the pipes connects between to points, and I can't visualize how to do this in blueprint...

[maiden wadi]

I'm not familiar with the game, but I imagine that the difference between C++ to blueprint would be fairly minimal. Likely comes down to what you prefer. But also depends on how you implement it.

For instance... You can either do a full data method and display that with blocks, by keeping a full array of data of the blocks, a list of which blocks they connect to, etc. Or you can make each block it's own self contained entity that holds it's own data for what it connects to and drive the game that way. But as for saving the state itself during gameplay, it won't be much different between C++ to Blueprint.

[native plover]

how do i make the trace go forwards a bit

from the socket location

[dawn gazelle]

Maybe this could help? Change the float in the multiplication node to increase how forward it is.

[native plover]

that's the end location of the trace tho @dawn gazelle

[dawn gazelle]

you're looking for what to place in your start of the trace, yes?

and you want that value to be a little bit ahead from the socket?

[neon sorrel]

Thank you for the idea, experimented with it and managed to use UTCNow and savegames to effectivly create a system for it. 🙂

[native plover]

yes

[dawn gazelle]

Ok, my example is "socket location" + ("actor forward vector (which is only a value that goes between -1, -1, -1 to 1, 1, 1" x "the float defined as a distance"). So it should just give you a small value ahead of where your socket is.

so long as you put a small float number into the multiplication box

[native plover]

ooooooo

i understand

why didn't i figure that out 😦

[dawn gazelle]

You were close in your example it looks like

[native plover]

thank you !

[split barn]

Does anyone know how to make the first person player simulate physics without having him move on his own?

I locked rotation and he shoots across the map in all directions

[true valve]

Is there a way to use select to pick based on a float variable that goes from -.5 to 1 or -1 to 2.

[barren flower]

Whats the easiest way to manage bulk data? Like, lets say I have a village sim with like, 300 villagers, each with their own attributes. How much money they have, color of their shirt, where they work. That sort of thing.

Ideally I would love to have them all stored line by line in, like, and excel spreadsheet sort of structure

But I also want to be able to bulk edit them. Lets say they all go to sleep in a barracks building. So the actual villager blueprint people disappear, and they only exist in this spreadsheet now.

But what if I cast some spell that kills every single villager with a red shirt? Or I delete the smithy? How do I search through for these values and either change them to unemployed, or delete the relevant row, respectively

Is this even possible out of the box?

Importantly, this data needs to be able to be rapidly accessed and updated in the game

or is the answer just literally hook a mysql database and be done with it?

[rotund basalt]

Just a tip: For those 2 booleans use an NAND gate then you can check if both are false (if they are you get true with a single compare)

[cold raft]

I am have a save game working but getting odd results when going to and from the loading menu (which is a separate level) - does the playerCharacter unload and reload when you do a openLevel? I am thinking it does due to spawn points

[plain flare]

Hey how can i storage info ?

I mean, for example i have an integer equal to 1, on the next level, I want to make this integer +1 (2). But when i moving into next level, this information doesn't increase

After second, On the next level, int should be 3, but it is being 2 if i wont storage that info

How can i save my int on whole game ?

[cold raft]

@plain flare - you can use the GameInstance to save info between levels (I believe)

[plain flare]

idk how to use it, but im gonna look tutorials. Thanks

[cold raft]

I made a new Game instance called GI_Sanct and stuck a single string variable in it - then get that data like above.

BUT - I am having weird bugs where my character isnt saving between levels, so shrug - may not work

[amber marsh]

is there an easy way that I can get the actor that owns a component? Like from inside the component itself

be able to quickly grab the actor its on.

[olive sedge]

can you not subclass widgets?

[amber marsh]

oh hmm I remember running into that same question

does not seem so

sad

[maiden wadi]

@olive sedge @amber marsh You can, but none of the designer widget stuff remains. You can subclass variables and code, the backend/graph part. But the look will be lost.

I do this in C++ for example, because I like to have specific functions I can call on any of my main widgets to pass information into them as I'm adding them to screen or whatever without casting to the specific widget class. So I have UUserWidget and then MyCPPUserWidgetClass, and I create MyInventoryWidget that inherits from MyCPPUserWidgetClass and also UserWidget class.

[primal rock]

I have the following Problem:
When spawning my Players in my Multiplayer System only the owner seems to get possessed correctly. Any idea how to fix this?

[maiden wadi]

Where and how are you spawning the pawns that are getting possessed, and how is possession being called?

[primal rock]

This is in the PlayerController

This is in the gamemode

[olive sedge]

@maiden wadi yes,I only need common variables but got an error msg.. Anyway, they have a common config szruct now instead of a base class

[trim matrix]

Hi all, i was wondering if someone could give me a way forward on a problem we am having...

We have a MP game in the making and we need HOST ONLY Menu/Menu items. We are using the Node "Is Sever?" but this does not seem to be working as intended, it all works fine on the first set of rounds(When you create the server from the menu) but then after you have finished and all clients are pushed back to the main server lobby the host has no host menu at all? here is the "Is Sevres?" bit we are using.

[gentle flare]

is there a way to control the size of the widget for a scene node in the BP editor?

Here's my "doorbell" up close:

And here it is a bit back:

It's annoying my OCD

I'm using scene nodes to group like components in the BP hierarchy:

[south meadow]

@gentle flare whats the issue?

[robust jacinth]

Box should be renamed to Box0, all boxes must be in numerical order, and OCD absolutely has to be spelled CDO because it needs to be in alfabetical order! (If you ask me, which you didn't so I should just shut up)

[gentle flare]

I no wanna see this big yellow sphere where the scene node is

[south meadow]

thats just a scene componnet or whatever icon. you wont see it in game

[gentle flare]

yah, but I don't wanna see it here in the editor

I'm gonna have buttons everywhere

Do I have to play the game everytime I just want to see what it all looks like without them big spheres everywhere?

Tried pressing G how you do in the editor, no luck

[maiden wadi]

@gentle flare search for billboard I think. Something like billboard scale or something. In that component.

[gentle flare]

no joy

tried opening all the inspector groups and going through every property available 😦

[odd ember]

if you've set g to something else it obviously won't work, but look for game mode under the render settings in the view port

(which by default is G)

[gentle flare]

Sorry, I didn't mean G in game, I meant in the editor, when you press G for game mode where there no widgets

Doesn't seem to be a thing in the BP editor window

[odd ember]

in the BP window you can replace the root with an empty Scene component. I thought you were talking about in the editor viewport, not in the BP viewport

[gentle flare]

I guess I can just edit it ugly in the BP editor and check it in the main editor window on another monitor in game mode

[odd ember]

I gave you options

the above will get rid of the white circle permanently though

[gentle flare]

they're not roots

[odd ember]

is it button door 1 and 2?

[gentle flare]

hey, wait a minute

dammit

It's not the scene node doing it, it's the child actor... where there is a billboard scale prop

[south meadow]

isnt that a child actor? is there a root in the child

[gentle flare]

I knew it was an id10t error

[odd ember]

well that's why I pointed it out

so in the child actor class if you replace the root you wont have the issue

like I said

[gentle flare]

oooh

[odd ember]

or just dont use child actors really

they are the devil

[gentle flare]

I get it now 🙂

so wait

there's a better option than child actors?

[south meadow]

i dont agree with that

[odd ember]

there's always a better option than child actors, but it's not necessarily an easier option

[gentle flare]

well, my button has functionality in it, using child actors let's me copy paste as many copies as I need and they all got the same func bada bing?

[odd ember]

why aren't you just placing the buttons in the world and hooking them up that way? you're strongly coupling buttons with doors as it seems right now

[gentle flare]

I wanted the ship blueprint to be self contained so I could load it dynamically when required

[odd ember]

so every ship will have a button in the exact same place 🤔 you might as well just parent a button to the ship so you can move the button independently in the world while retaining it within the ship

[gentle flare]

Sorry, instantiate it

[south meadow]

theres gonna be a lotta explanation . without seeing the code... cant really say if its right or wrong. theres nothing wrong with child actors.. .. there is some bugginess with the editor sometimes with them but thats with structs as well and many other things

[odd ember]

generally child actors skirt architectural rules, they're a pain to debug properly and they are performance hogs

[south meadow]

hmm? that seems kinda silly since part of the reason to use an existing engine is things like physics?

[odd ember]

plenty of stuff in the engine that you shouldn't be using

all bp actors start with tick on and epic recommends that the first thing you do in a new actor is to go in and turn tick off

[south meadow]

and you think child actors and the entirety of physics shoudnt be used?

[odd ember]

child actors in my opinion should be deprecated

[gentle flare]

I'm trying to build some basic interactions for star citizen like gameplay, so the ships aren't really things that just sit there like a level design feature

that I can just heap stuff on top off in the main maps hierarchy

I want to spawn ships as dynamically, so they sort of need to be all packaged up in one thing that gets instanced

[odd ember]

I don't know what star citizen (or which part of star citizen) you're trying to make but for ships to work both as a vehicle and as a space you're going to have to make a lot of custom logic work it sounds like. definitely not something I would attempt in BP alone

[gentle flare]

mmm... I'm most the way there...

the little sleds were from a helicopter tute I did the other day

the flight model is pretty basic but it's mostly what I want

[odd ember]

but even so you could make it within a single actor and hook it up with scene components instead of using child actors for instance. or create hook in points where you spawn actors and attach them, completely without the massive overhead that you get from child actors

[gentle flare]

so... I can put my BP button in a scene node?

[odd ember]

a scene component is just a component with a transform. static mesh components all derive from scene components for instance

[gentle flare]

yah that's what I thought

[sharp fox]

Hello! Does anyone know how i can make when player holding d and press q then launch player to (d - right, a - left) ?

[odd ember]

so you could probably make a derivation from static mesh component and add logic to it as you want for instance

equally you could also spawn the actor attached like I said

[gentle flare]

so spawning in main map is much better than child actors? why is that?

that'd mean I basically couldn't preview the end result in the editor, I'd have to run the game everytime I wanted to see what it looked like :/

if you have to do it that way whats the point of having an editor?

[odd ember]

how do you not do that anyway right now?

like you cant test functionality in the BP editor

or even space use

[gentle flare]

ah, I just mean the look and design

[odd ember]

I do as well

your game isn't going to be played through the BP preview window

[gentle flare]

well...

here I am in the BP editor

I can see where my button is, I can see if I like it's placements size, how everything looks together

but if I do spawning, all I see here is a socket

[odd ember]

you can't see how it looks from the player camera

or how its relation is to the ground etc.

or indeed how the environment would affect it

[gentle flare]

this is enough of what I want here

for that stuff I'm happy to play (and for testing func)

but you dislike of child actors is obviously not coming from nowhere, what has your experience with them been?

[odd ember]

just be careful that you're not setting yourself up for unintentional shenanigans because you want to skirt these things

[odd ember]

I've given you very good reasoning for not to use them above

[gentle flare]

I meant specifically, you mentioned being a performance hog, is that 5 times slower, 10, 100 etc

cos I get the feeling I'll be fighting for frames at some point sooner or later

(don't we all)

[odd ember]

it's definitely more overhead than spawning an actor in world, but I can't tell you exactly how much. but if you're spawning a ship full of them then you'll notice it for sure

[gentle flare]

hmmm

[sharp fox]

Hello! Does anyone know how i can make when player holding d and press q then launch player to (d - right, a - left) ?

[gentle flare]

if I was a young person I'd be all like nah she'll be right and then regret it later lol

hmmm

[south meadow]

@sharp fox google "launch character"

[odd ember]

since you're going to be building ships I think you should put some thought into establishing a ship building workflow that is optimized for performance and usability

[sharp fox]

Yup but i wonna do when player HOLD D and press q then launch player to right

[gentle flare]

well, that's why I'm being so nosy here now 🙂

[odd ember]

which may require a little more than just being able to preview a ship with child actors in BP

[gentle flare]

most painful part so far is placing collision primitives everywhere

no wonder crates fall out of the ships all the time in star citizen

[odd ember]

to me a ship would seem more like the concept of a "blueprint", not to be confused with BP. as in, you're establishing where everything is in the ship, let the game build it, and then you inspect it

[sharp fox]

So anyone know how to do this?

[gentle flare]

you might need to try and be a little bit more specific natixo, I don't really understand what you're trying to ask

launch: you mean jump?

[sharp fox]

how i can make when player holding d and press q then launch player to (d - right, a - left) ?

[gentle flare]

dude

just copy and pasting the same exact thing when I just said I didn't understand what you mean...

[odd ember]

lmao

[sharp fox]

when player hold d and press q launch character to right

[gentle flare]

ok

[sharp fox]

and this same on left side

[gentle flare]

so launch

what do you mean by launch?

[odd ember]

so like a side step

[gentle flare]

^ ?

[sharp fox]

yea but launch

[gentle flare]

https://giphy.com/gifs/thisisgiphy-reaction-audience-l4HnKwiJJaJQB04Zq

what. do. you. mean. by. launch.

[odd ember]

maybe the launch node?

just a guess

[sharp fox]

OMG Im using Launch Character and i must have launch character

[gentle flare]

https://giphy.com/gifs/mrw-help-tree-kGCuRgmbnO9EI

[sharp fox]

Maybe im stupid or im stupid

[gentle flare]

You're not stupid

You're just refusing to explain in more detail what you mean by "launch"

How is you "launch" different from a side step?

[sharp fox]

I have to do side step but not side step

side Launch

[gentle flare]

You sir

Are an excellent troll

Well done, you had me going for a bit there

[sharp fox]

xD

[odd ember]

in your character

there is a node

[sharp fox]

ok

[odd ember]

called something like Get MoveRight

[sharp fox]

um Get Move right axis Name?

Im noob at this

Where it is?

[odd ember]

yeah it might be get move right axis or something

can you show me the node?

[odd ember]

hmm never used arch vis so it might be called something differently there

try to look for get axis and see what comes up

what you're looking for is a node with a float output of axis value

[sharp fox]

get forward axis?

[odd ember]

get right axis

perhaps

[sharp fox]

nope

[odd ember]

the moving right

node

should be it

[sharp fox]

ok i get it

[odd ember]

can you show me your logic so far

[odd ember]

lol

so you haven't set it up yet?

with the Q button and launch?

[sharp fox]

i have

[odd ember]

show me

[sharp fox]

Wait i have this

[odd ember]

ok

and launch is set to Q yes?

just to be clear

[sharp fox]

yes

[odd ember]

cool

here's what you do

first

instead of using the capsule's rotation etc., just use GetActorForwardVector

and while doing that, also grab GetActorRightVector

[sharp fox]

wait i have to do q and w - forward, s - backward, d - right and a - left

[odd ember]

yeah step by step

just get those nodes first

[sharp fox]

i use it before and it make first launch is normal and second launch is HYPER SPEED

[odd ember]

that's fine

you will also need the MovingForward node

[sharp fox]

Moving Forward is my axis

[odd ember]

you got the MovingRight node before

there is a MovingForward node as well

[sharp fox]

so i use get moving right (as axis)?

[odd ember]

yes

both of them you will use

[sharp fox]

ok

[odd ember]

get all of the nodes in first

then we arrange the logic

[sharp fox]

ok i got it

[odd ember]

you'll need a vector + vector node and a normalize vector node

[sharp fox]

ok

[odd ember]

the normalize vector may just be called normalize

I forget

[sharp fox]

like this?

[odd ember]

just leave them unhooked for now. you still need the GetActorForwardVector and GetActorRightVector

[sharp fox]

ok so what i unplug

[odd ember]

everything

you'll need 2 vector * float nodes as well

[sharp fox]

like this?

[odd ember]

yes

the 2 conversion nodes you can remove

[sharp fox]

ok i have it

[odd ember]

so you have all the nodes now?

including GetActorRightVector?

[sharp fox]

yea

[odd ember]

show me

[odd ember]

ok where is GetActorForwardVector?

that's the last node you need

[sharp fox]

i does'nt have it

ok now i have it

[odd ember]

cool

[swift coral]

Good Afternoon, I know my request follows multiple topics - mainly widget, blueprint and material - but I think this is the most appropriate category. I urgently need help on this topic, because its for an artschool application, the deadline is approaching and Im stuck on an issue that worked a week ago. But, thanks to unreal-magic, my character customizer isnt working anymore in the way it should: as you see in pic 1, my thirdPersonCharacter has a groom with a material assigned to. In pic 2 you can see a part of the widget witjh HSV sliders to control the color of the fur. In the WidgetBP Graph you see, that on the event "ValueChanged", the value h,s or v is changed. In the EventGraph of my ThirdPersonCharacter, in pic 4, the widget is created and all its variables are "collected", I then create a Dynamic Material Instance for my groom and its material on every tick. Then I transfer the 3 variables via a vector parameter to my material, as you see in pic 4 and 5. The parameter is taking and trough some nodes, is converted to HSV and being used as the BaseColor. Its important to note, that a week ago, everything worked fine, the hair changed on changing the sliders. But after testing some things and pulling on some nodes, it doesnt work anymore. Can anyone spot a mistake in these screengrabs, or point me towards an area where the mistake could be located?

[odd ember]

@sharp fox here's what you do

use one vector * float with GetActorForwardVector * MovingForward and the other with GetActorRightVector * MovingRight

[sharp fox]

ok wait

[odd ember]

add both of them together using the vector + vector node

then normalize

[sharp fox]

ok

[odd ember]

show me how you've hooked it up

[odd ember]

cool

so now take this set up, and go to your launch logic

and plug it into the vector * float where you add the speed

[sharp fox]

OMG THANK YOU SO MUCH <3333

[swift coral]

Is this located here correctly or is it more useful anywhere else?

[odd ember]

I'd put it in the main channel as it has multiple areas tbh. debugging wicked problems isn't great over the internet though so I reckon you are largely on your own

[swift coral]

so you mean #ue4-general ?

[odd ember]

yes

[swift coral]

k ill give it a try, otherwise im really lost haha

[odd ember]

good luck

[swift coral]

thx

[deft snow]

Does anyone know how to offset the trigger frame for a blueprint based explosion effect in Unreal?
I want to use the explosion in the sequencer, but it always one-shot triggers on frame #1. The blueprint occupies the entire timeline, so I can't slide it down the timeline. I can't find any temporal offset for the blueprint.

[rigid tundra]

project crashes at 93% that is some asset error, but the thing is when I take out the broken files and then start it loads, when I put them back in everything works fine. If I want the whole package, there are a lot of errors in the blueprints that have to do with the plugins, but there are no errors in the blueprints themselves, only in the log.

[orchid garden]

well, just looking at what you gave, i'd make sure your custom Tick events are being linked to a timer so that they are being fired off.

[verbal bobcat]

I am really horrible when it comes to drag and drop inventory systems(or inventory systems in general) does anyone know any good tutorial or something that can help me?

[orchid garden]

https://www.youtube.com/watch?v=kP_g9WO-TpE&list=PLGm9gBuuMTevunNJbvq2PdjWGaCv19jxr&index=1

that one will walk you through all the various parts of setting up a working inventory, its a good learning source. you can make a fully functional inventory if you follow along and do what he does.

link should take you to the full playlist

[verbal bobcat]

Oh ok, yea I was confused at first with a 10 minute only video, but after I clicked on the link it gave me the full playlist, thank you!

[orchid garden]

np, good luck! 🙂

@verbal bobcat he has a discord channel too, so if you get stuck on something you can ask questions there: https://discord.gg/pAaRF6Km

[verbal bobcat]

oh nice this might come in handy

[kindred mountain]

hello guys , i am new here. i want to ask you a question . i work with the UE4Duino Plugin but the last upgrade only works on Unreal 4.23 Does anyone of you have a version that works on unreal 4.25 or 4.26

[exotic cradle]

Yeah you right lol. Didnt even consider it

[stoic palm]

[weary jackal]

In the open card functions, return those card value strings

[stoic palm]

One message removed from a suspended account.

[stray island]

Random integer in range chooses from 0 to 2 randomly

What if i want 0 then 1 then 2

As sequence

[weary jackal]

Use for loop

[stray island]

Not expensive?

[weary jackal]

If you want to make a different random card pack and don't know how many cards it will be. Then you can make an array and append it every time you open a pack

[weary jackal]

Nah

[exotic cradle]

So whats the difference between the two Attach Actor to Socket blueprints you showed me besides the obvious of one being boolean and another an actor reference

[stray island]

Only random in range working but i dont want it random i want it to respect the list order

[weary jackal]

Oh. Use counter

And after each execution, increment the value

An integer starts from 0 and at the end of execution add 1

[stray island]

Cant find a counter node

[weary jackal]

No, make an integer and set its value to 0

So first time it will get 0th index

Then after add +1 to it

[unique hollow]

I've been thinking about making a fall damage BP for my character

and I want to avoid event tick

I wanted to use "On Landed" for it

problem is, if I check for Z velocity of my character

when the "On Landed" event fires, will it detect the velocity at which it fell from

[stray island]

Then how would it stop at number 2

[unique hollow]

or will it detect it as 0

[unique hollow]

just tested

it does keep the value from how fast I fell before landing

[weary jackal]

Check if it's not == 2 then add +1 else set it value back to 0

[weary jackal]

If you ever need to take a screenshot of your screen when you're on windows

Oh this worked

@weary jackal thanks!

[slate apex]

any freeware plugin available for dialgoue trees?

I can afford it, but i'd rather not since money's tight.

So even some youtube tutorial's dialogue would be fine.

cause man, i suck at it

[zealous moth]

@slate apex honestly, the dialogue plugin is the best thing ever. I have it and it is amazing.

[slate apex]

how much..?

[slate apex]

i swear if its like 200 euros

[zealous moth]

I have this one https://www.unrealengine.com/marketplace/en-US/product/dialogue-plugin

[slate apex]

yeah

i had my eye on it

[zealous moth]

it is frankly amazing - works out of the box, the documentation is solid, and it's like a 10 min yt video on how to use it.

[slate apex]

is dialogue and UI already built in?

like cast to viewport.ect?

[zealous moth]

yeah, the ui is super basic but he has documentation on how to modify it

[slate apex]

well

yeah, so long as its using widget

it shouldnt be that hard.-

[zealous moth]

the best part is that conditions and triggers are built in so you don't have to rework it

[slate apex]

I've been video editin before, and its basically identical.

WAIT NO WAY

FUCK

Now i wanna buy it

but man.

65 is quite an asking price for a hobby with no guarantees

[zealous moth]

you can set your own conditions and the dialog will do a check or if you talk to someone and want to open a door, it will open it

[slate apex]

hhhnngh

[zealous moth]

welp, it's about 3h of work so take that into account.

[slate apex]

bro i spend days

[zealous moth]

cheaper than to make it yourself

[slate apex]

trying to figure out normal dialogue

[zealous moth]

yup and this is out of the box

[slate apex]

my dialogue and interaction system is a mess

lemme show

it isnt as convoluted as it was then

this is bout 2 months old

but

still represents it

[zealous moth]

i made a few attempts at it and it's a pain.

the plugin was well worth it

[exotic cradle]

Who thought attaching two objects with sockets would be so stressful lol

[odd ember]

I mean if you're not making a tree out of linked list classes, then what are you doing

[stoic palm]

One message removed from a suspended account.

[exotic cradle]

So you don’t want them in an array but each their own seperate variable?

[odd ember]

this sounds like an interesting problem. what is it you are trying to do? as in, in the game

[stoic palm]

One message removed from a suspended account.

[exotic cradle]

If he made an array and added to it from the string selected from the for loop he would have an array of seperate strings

[stoic palm]

One message removed from a suspended account.

One message removed from a suspended account.

[exotic cradle]

But it would give you 3 seperate strings

[odd ember]

so go through what happens up until that point

[exotic cradle]

You can also use a format node and type in Card{number} in the box and attach a string that way it will be formatted as Card 1,2,3 etc

[stoic palm]

One message removed from a suspended account.

[odd ember]

show me what's before that get

[stoic palm]

One message removed from a suspended account.

One message removed from a suspended account.

One message removed from a suspended account.

[odd ember]

so... why are you using a map here?

[stoic palm]

One message removed from a suspended account.

One message removed from a suspended account.

[odd ember]

you could do that with an array

[grave relic]

Could someone help me, i have this in the level blue print, when ive picked up 2 parts of a key and go into the trigger the sequence should play(it does) but then for some reason it resets to its starting posision

[odd ember]

an array has an index, if you find something by that index, it's going to return the card that you want

now

because you've set RandomCard as a variable

and you pull a Get from that

it's always going to give you the same card

if you want 3 random values, use the random directly on the get

[stoic palm]

One message removed from a suspended account.

One message removed from a suspended account.

[odd ember]

in that case use the loop as has been suggested before

[stoic palm]

One message removed from a suspended account.

[odd ember]

anything on the right of keys can probably be deleted and you can place your loop there

[stoic palm]

One message removed from a suspended account.

[odd ember]

anyway your BP is kind of a mess so it's a bit hard to read in places. I'd just have the card pack be an array htat you loop over 3 times, picking a random index each time, and add that to a secondary array, kind of like you have done

then

using the secondary array, loop over that to create separate string entries

you'll have to have some container created already in your widget that can display those 3 separate strings

so e.g. a text box or what have you

that should be it

[dawn gazelle]

Also instead of getting length and doing -1 to it, you can do Last Index on Arrays which will return the last valid index in the array.

[odd ember]

yeah that will be safer as well

[dawn gazelle]

And if you're doing a multiplayer game, you may want to avoid using Maps, as they cannot be replicated unfortunately :/

[shell heath]

Hey you guys, I am trying to figure out how to make a card in game but not give access to it immediately.
Anyone know how to do this?

[gloomy linden]

can you elaborate?

[odd ember]

no one will have access to a card unless you allow them to have it

[dawn gazelle]

Creating a shuffled deck of cards (using an enumerator of suits), and a structure of the card suit and value, including the ability to set how many decks you'd want to use.

Example of pulling a card from that deck

[gloomy linden]

are card games hot right now or is this just a coincidence?

[unique harness]

I just changed the logic inside the function and was showing you the new version

[orchid garden]

hrm... i wrote a couple card games in flash... im sure the coding for that wouldn't be hard to convert to blueprints....

[exotic cradle]

Ahh I was confused because some of the nodes I tried to connect wouldn’t and so now I mean it spawns the item, snaps it than deletes the previous object lol

Like the Detach it doesn’t let me connect the parent actor node and for inside the Attach Actor to Socket it doesn’t let me Attach to Socket as the target I can’t change

[shell heath]

Ok, let me change the scenario I guess.

So If I want the player to start the game with a certain character and they can unlock more characters laterite choose from. I have a problem where I can just choose to use ANY character I have made.
So how do you make conditions so that those characters are not visable or in the menu?

[exotic cradle]

Can use character? = 0

[odd ember]

make a character "inventory" array where you store the names of characters available and hand that to the player

[orchid garden]

make a array for the player that contains booleans, and if the boolean is true, enable/add the character in the list, if its false, disable/remove it.

[odd ember]

don't give them the master roster lol

[orchid garden]

if your doing like a streetfighter type selection, just disable toe button that lets them select the character if the boolean is false.

[shell heath]

Can this be simplified please?
I’m new and don’t understand what you’re saying.

Also, these characters can have multiples (like a hatch’s game).

[odd ember]

I gave you the simplest solution

how do you store the chaaracters currently?

[edgy halo]

how do i disable collisions for specific actors?

[shell heath]

Ummm, I am using the CCG toolkit currently but I’m not sure how it stores cards.

[odd ember]

so... can you show off your logic?

[edgy halo]

I mean that I have a class called player, and it is a multiplayer game, every person playing the game gets his own actor from the player class, but i want to disable collisions for a few of those actors temporarily

[odd ember]

#multiplayer is probably better to ask about which things replicate and which things dont

[edgy halo]

its not multiplayer as of now

i dont need anything related to multiplayer help in this

[odd ember]

but if it will be you need to ensure that it works in multiplayer too

which is not a given

[edgy halo]

i will handle that later 🙂

[odd ember]

yikes

well you do you

SetCollisionEnabled is a function

[edgy halo]

i first need to get the basic game setup...its my first game so...

but i want the collision to not work for only two objects

[odd ember]

so... set it on them?

[edgy halo]

or one object

no what i mean is

@odd ember by chance have you played bomberman

[odd ember]

sure

[edgy halo]

just gimme a second

https://youtu.be/AuZneFxtl10?t=139

@odd ember as you can see in this video at this time, the person is standing on the bomb

[odd ember]

yeah so you place the bomb without collision and just give it collision once they exit

[edgy halo]

I need to disable the collider while there is a person standing on the bomb

[rough wing]

This is basic collision profiles

[edgy halo]

only for that person

[rough wing]

You can manually set object collisions to ignore each other

[odd ember]

use a profile per player yeah

[edgy halo]

but anyone else shouldnt be able to walk through the bomb

you mean collision channel?

[rough wing]

Yea

[odd ember]

but also I would double check what replicates and doesn't replicate if you plan to do this multiplayer

[rough wing]

Is it multiplayer

[odd ember]

because multiplayer is not something you "do later"

it's something you need to have in mind from the beginning

[edgy halo]

hmm, ok

but i guess there's nothing much to do for multiplayer

[odd ember]

there's plenty

you'll find out

[edgy halo]

i can test around whether i should replicate to server or not

ok ill keep that in mind

[odd ember]

go to the multiplayer channel, have a chat with them folks

[rough wing]

Testing will take 90% of your time

[edgy halo]

thanks 🙂

[odd ember]

and theyll tell you

[rough wing]

There is a networking compendium or something

[edgy halo]

alright

[odd ember]

yeah

[rough wing]

Search it in google, it will help

[edgy halo]

but before that i want to get familiar with the engine

[odd ember]

probably those same people can link you

well youll have to do both

[edgy halo]

and this is my first projec

[odd ember]

if you want multiplayer

so now is probably a good time to decide if it's worth it or not

[edgy halo]

ill do that too parallely then, but first i just need the bomb spawning to work

[rough wing]

@edgy halo Although you can learn networking on the go for your first proejct. It's gonna bother you a lot and you're going to keep deleting your half made projects/

You should start single player imo

[odd ember]

yea pretty much

[edgy halo]

can you assist me in implementing what you meant?

[rough wing]

No :d

[odd ember]

I wouldn't recommend multiplayer until you're years into game dev

[edgy halo]

Hmm

[odd ember]

and even then only when you understand how much work multiplayer truly is

[edgy halo]

but its a basic game and i just need to choose whether to make the objects to replicate locally or server right?

[rough wing]

If you just do it like that its gonna be laggy and buggy

[odd ember]

it's not just that

[edgy halo]

what if i make it local multiplayer?

that's not harder right?

[rough wing]

Thats something else, thats basically singleplayer

[odd ember]

yeah

one instance is fine

[edgy halo]

hmm, so can you just tell me what you meant

[odd ember]

it's when you start having multiple instances of the game

[edgy halo]

so @odd ember i just disable the collider for the components which are overlapping?

[rough wing]

How many players do you have in the game, is there a limit?

[odd ember]

well you'll still need to do a lot of the same notions, just you dont have to care about server replication as your game mode essentially becomes your server

[edgy halo]

8

or 4

still deciding

[rough wing]

If there is a limit you can simply create different collision channels for each player

[odd ember]

start with 2

yeah that's what I said

[edgy halo]

hmm but its limited to 18 right

[odd ember]

you're not going to be using 18 collision channels

[edgy halo]

is it possible to do something like have overlap and block on?

[rough wing]

I think it should be alright for 4-8 players

There are 3 types -ignore-overlap-block

[odd ember]

apart from the basic channels you need 1 per player and that's it

[dusty ibex]

Is there a way to see blueprints that inherit from some class? In editor or in gameplay

[rough wing]

Find references maybe?

[edgy halo]

hmm but what exactly is the advan\tage to do that?

[rough wing]

It's easy

[odd ember]

that you can handle bomb ownership easy

[exotic cradle]

Ohh so the Boolean was old version and actor was the new version

[odd ember]

reference viewer

[rough wing]

@dusty ibex

[edgy halo]

hmm but is there no way i can tell unreal engine that

ohh block this object

and ignore this one

during runtime?

[odd ember]

you can do that in many ways, but this is the simplest

we're giving you a solution that is easy to work with

for your first game

not sure why you are looking a gift horse in the mouth here

[edgy halo]

i just wanted to learn more sorry if it seemed like that😅

[odd ember]

if you want to learn more go through the docs for collision

don't be a help vampire

[edgy halo]

i did but there's lesser to understand from there related to my issue

[exotic cradle]

Also tutorials on YouTube as well

[rough wing]

Help vampires suck

[edgy halo]

sorry apologies from my end

didn't mean to seem like that

one last question😔

[shell heath]

So when I make this card it is a Ali able in the game already.

Should I just make this project from scratch so that I’m not confused by all the already made systems in this game?

[edgy halo]

how can I change the collision responses during runtime?

[odd ember]

SetCollisionEnabled

[exotic cradle]

A lot of stuff you just gotta watch tutorials semi-related to how you wanna do things than make an attempt to do it than if you can’t figure it out that’s usually when I come here. I’ve been here a lot recently though because there is little documentation at all for what I’m trying to do but I have found great help here

[odd ember]

I already told you

[edgy halo]

ohk sorry to ask again

extremely sorry for the bad ettiquete

[odd ember]

yep

[rough wing]

@shell heath I like studying other projects. When there is stuff I don't understand I usually start creating my own project by learning from the example and adding on top of it.

[exotic cradle]

It’s all good I got reemed by a mod earlier this week lol

[odd ember]

keep the other project as a reference

but don't build on top

[edgy halo]

reemed?

[odd ember]

put into place

[exotic cradle]

^

[odd ember]

but like

square peg into round hole like

[edgy halo]

oh my bad

[unique harness]

yes

[exotic cradle]

The is socket available is just a pure function to see if the socket is occupied

[unique harness]

correct

[exotic cradle]

So how is the socket set to occupied for the child bp?

I’d probably set that after the object is placed and the two sockets are attached

[unique harness]

I would do that in the OnAttach method

[dawn gazelle]

On your bomb, this would give you the absolute basic ability to place your bomb where your player is, but then you couldn't overlap with your bomb once you step outside of it. The thing is, any other players could also step on to it while your player is still on top of it until someone finally steps off of it, after which it will block everyone.

[unique harness]

which is passing the attached actor and the socket it was attached to

so you should be able to interpolate which socket on the child is now in use.

You will probably need an OnDetach method as well

[unique hollow]

I've been working on my health system

it's a bit messy

but should work

[exotic cradle]

Okay yeah I also realized I don’t have my socket locations even referenced in any of the blueprints

[unique hollow]

this is a trigger that hurts you

should work

[unique harness]

The scene component is to store the socket location

[unique hollow]

damage causer is self, damaged actor is playercharacter

[edgy halo]

Yes I had done that, but I want to allow anyone to go through

Is there anyway I can check actor's name, and then choose whether he should collide or overlap?

[unique harness]

Looking good, you should consider adding a method called something like "Modify Health" and do this logic inside there and calling it off the Event Any Damage. You can also add a OnHealthModified delegate for use in the UI.

[exotic cradle]

“Get display name”

[odd ember]

you can but it's going to be buggy

the collision profile solution is less buggy

[edgy halo]

No but it should then choose whether to collide or overlap? I got the name part

[edgy halo]

Ohk, but if it is a larger game for example, then how would one approach this problem?

Ah nvm

[unique harness]

Collision Profiles is what you want

[edgy halo]

Im being a help vampire now ig

[edgy halo]

but its limited to 18 right

[exotic cradle]

Yeah was about to say collision profiles are your best bet

[unique harness]

It is unlikely you would ever need that many

[edgy halo]

yeah but for a larger game for example?

where there's maybe more than 18 people...I was thinking of developing a battle royale from this

[unique harness]

well think. Fornite is made in UE4 and doesn't have an issue with 18 profiles

It sounds like you're overthinking how they work

[edgy halo]

that was exactly what i was thinking

[unique hollow]

here

is a mega weird thing

when I run the game in a separate window

or when cooked

my UI is fully fine, a long with all its widgets

use the main viewport and

not sure where to exactly put it, probably in UMG?

could be just a general problem

[unique harness]

yes, your positioning settings in UMG are a bit off

[edgy halo]

maybe, you should change your camera's aspect ratio

[unique harness]

That's not the issue

[unique hollow]

yea it can't be

[unique harness]

Your health text should be parented to the gray background

[edgy halo]

the editor's view is longer so it can be

[unique harness]

well the camera doesn't affect UI so it can't be.

[unique hollow]

ok the borders behind it had wack anchors

fixed it now

[unique harness]

Nice, would you mind showing how you're updating the health text?

[unique hollow]

it's a simple bind function, here

[unique harness]

That's what I was afraid of. You don't want to use the bind functions because they are executed every frame. Your goal should be to create what is called an "Event Driven" UI.

So even when your health isn't changing, this code is being executed

You want to only update the text when the health changes

[unique hollow]

can you toss me a tutorial for it then or an example

I'm not sure how I'd be able to update the text when called

[unique harness]

Yes a simple way is using Delegates or Event Dispatchers as they're called in BP

https://docs.unrealengine.com/en-US/InteractiveExperiences/UMG/HowTo/EventBasedUI/index.html

Example 3 talks about it here

[unique hollow]

alright, thank you

[unique harness]

Doing this will make your UI really performant and optimized

Simple little change that can go a long way for performance

[unique hollow]

yee, ty

[unique harness]

no problem

[unique hollow]

I'll add it in rn

[unique harness]

cool, feel free to ping me once you get it working or have any questions

[unique hollow]

hmm

[unique harness]

That's a variable that was created to store a reference to the player character

[unique hollow]

yee

[shell heath]

Okay, so I tried to watch a video but there are too many options for me to understand what each one is.

So I am starting by making an Inventory. How do I begin to make an inventory tho?

[unique hollow]

is it just

a normal Actor Reference

[unique harness]

It should be PlayerCharacterGL

[unique harness]

Well that depends on what kind of inventory you are making

[unique hollow]

I did try that but then

mine vs tutorial (docs)

[unique harness]

it looks like you created the health dispatch on a different class than your player character class

[unique hollow]

lemme look into that

oh yea I did

I have two separate player classes, one is deprecated

I am making cards that will be placed on a board. So I assume the “inventory” would just be a list of all the available cards in the game?
And then I would create another “inventory” for the specific character in which they start the game with?

[unique harness]

You should only need one "inventory"

you can reuse it if needed

[odd ember]

any inventory will just be a pool of whatever you have. a board state is "inventory" too

just the board's inventory

[unique harness]

I would start with making a UMG Widget BP called inventory, and another UMG Widget BP called Inventory Slot

Inventory Slot would be the representation of the card

[unique hollow]

I got the health stuff set up

it now only calls when needed

[unique harness]

Inventory would be a Horizontal Scroll Box with a dynamic number of Inventory Slots

Then an Initialize function in the Inventory BP that accepts an array of cards and creates a slot for each card and adds it to the scroll box

[unique harness]

Awesome 😛

[dusk basin]

Anyone have Any idea how i can replicate this wormhole effect? the blueprint that contains this is a spectator pawn with the "wormhole" attached and i want this animation to happen to all players when the host presses start

[unique harness]

Might want to ask in one of the content creation channels

[dusk basin]

@unique harness what channels in specifically?

[unique harness]

I'm not sure, I'm a programmer :P. Probably #graphics, #virtual-production, or #visual-fx

[shell heath]

So Inventory slot would basically be “view card” so you can look at its stats/effects?

[dusk basin]

its more of a blueprint based thing though the animation is already triggered with a interface and is already setup

[unique harness]

Inventory slot would be the visual representation of the card

You might have another widget that when you click on a card, displays a more detailed version of the card with the information

I can show you an example in a second

@shell heath

So this "whole" image would be the inventory widget

each card would be a slot widget

when you click on a card, it displays a larger one

so you can read the text and effects

[shell heath]

So I only need the UMG widget BP for the card and then the UMG widget BP for the cards to appear correct?

[unique harness]

yes

[dusk basin]

this is my logic for the wormhole effect when the host presses start game my question is my main menu visuals are driven by a render target thus when removing all widgets itll display the wormhole in theory is there a need to use the possess node if this animation happens automatically

[unique hollow]

I'm having a problem with this mess

I'm using a print string for debugging

and it wants to deal 98 damage for some reason when I enter the trigger

OH

[dawn gazelle]

It's outputting your health - the damage

[unique hollow]

I just realized why it happens

yeah

I used to set the health to that equation

now I realize the problem

I am terrifyingly dumb

[shell heath]

Thanks, I’ll start on figuring this out and I’ll comeback if I get stuck. Appreciate it very much

[unique harness]

No problem, good luck

[unique hollow]

now it works properly

[dusk basin]

can anyone answer my question if there is a need to use the posses node if A the animation happens automatically and B the wormhole is the default pawn in the main menu

im assuming not as i dont need any input driven to the wormhole itself but i just wanna make sure

[dawn gazelle]

possess is meant to transfer a controller to a pawn. if you have a default pawn set, then technically any players that spawn in would get their own wormhole.

[dusk basin]

ok then that answers my question thank you '

[trim matrix]

Is this new or did I just not see it before 😆

[dawn gazelle]

That's been there for a long time 😛

[trim matrix]

Welp

[dawn gazelle]

Save you a couple of nodes there 😉

[dusk basin]

Anyone know how i would get a refrence to my default pawn aka my wormhole? for each connected player

[unique harness]

GetPlayerController()->GetPawn()

[dusk basin]

in blueprints

[unique harness]

same thing

[dusk basin]

ok

[unique harness]

^

[dusk basin]

im assuming id have to use that to cast to my portal

to then use as a ref

[unique harness]

yes

[dusk basin]

ok

[unborn maple]

how can i go about removing the main menu once i click on the button to open a new main menu? i cant seem to remove the menu after clicking on button

[unique harness]

you probably don't want to remove it, just hide/unhide it

[unborn maple]

even when starting a game?

[unique harness]

yes

[dusk basin]

so i was doing some debugging and apparently the cast to my portal is failing im assuming its failing because its not the controlled pawn but it is set to my default pawn class

any suggestions?

[unborn maple]

how will i hide it because i cant seem to get the widgetin game mode

to set the rule for it

[dawn gazelle]

What are you casting from? Spook?

[dusk basin]

from the controller to the get controlled pawn to the cast @dawn gazelle

[unique harness]

Typically I add all my main HUD widgets to the HUD class so I can access them from there.

[unborn maple]

yes i have one main menu with everything as hud class are you meaning interface?

[dusk basin]

the all player controllers array gets set everytime a new player joins

[shell heath]

So I thought that CCG toolkit would help me figure out what a “UMG widget BP” is but it uses a “data sheet” to store cards into.

So what exactly is a “UMG widget BP?”

The most I’ve done with widgets is create the main menu and move to different places (story, options, exit) with buttons.

[unique harness]

no there is an actual HUD class

[unique harness]

yes a widget blueprint

[unborn maple]

yes i have a HUD display

should i be casting to hud display to hide it

[odd ember]

heads up display, display

[dawn gazelle]

Perhaps portal doesn't inherit from Pawn?

[unique harness]

I don't think you're understanding me

[unborn maple]

lol cranz sorry im new

[unique harness]

i'm opening the editor, one second

[unborn maple]

this only my 3rd small game im making.

[dusk basin]

@dawn gazelle i would think its because the array only gets set on post login meaning i would have to test on built copy again correct me if im wrong

[odd ember]

there is a class

called HUD

[unborn maple]

yes i have that as a created class

[unique harness]

is it a child of HUD?

[odd ember]

badass metal band name tbh

[dusk basin]

@dawn gazelle its a spectator pawn so you are correct

[odd ember]

children of HUD

[unique harness]

lol

[unborn maple]

i dont know how can i check that

[unique hollow]

I wanted to make it so that when the player takes damage, the camera basically gets "punched"

how would I be able to do that

[unborn maple]

lol i just know i made a user widget

[odd ember]

camera shakes

@unique hollow

[unborn maple]

i just know i made a widget called main menu

[unique hollow]

oh

[unique harness]

@unique hollow

[unique hollow]

alright

[unborn maple]

so i believe it is not a child

[unique harness]

So what I'm saying is you can create a HUD class and store your widget references there

[unique harness]

as an easy way to access them

[unborn maple]

i have a hud already for the in game stuff

[shell heath]

user interface-> Widget BP
But how do I create a list of cards from the screen?

[unborn maple]

should i just tie it in to that

[dusk basin]

ok so get spectator pawn dosent work even though its set to portal

[odd ember]

as boxes

that you fill

with images

and text

[unique harness]

no, a HUD and the actual HUD class are different

[dawn gazelle]

Spectator Pawn still inherits from Pawn, so that's not the issue. A cast on my end works correctly. When you do a print string off of the cast failed does it display on screen?

[unique harness]

@unborn maple in your game mode class,

see the BP_MyHud

[dusk basin]

yes @dawn gazelle

[unborn maple]

yeah i have that as breakithud

[odd ember]

so it has to be a hud subclass then

[unique harness]

ok so in that class do this

[shell heath]

So every image will represent another card?
How would I explain rarity/stats to the game then?

[unborn maple]

ok.

[odd ember]

well first, you create a widget for the card itself. in there you can prop it up with all its attributes... that you can probably get from a data table

[dawn gazelle]

What is the Parent Class of BP_Portal?

[dusk basin]

@dawn gazelle

[dawn gazelle]

🤔

[unique harness]

@unborn maple now you can do this pretty much anywhere

[dawn gazelle]

Can you do something like this, and see what the controlled pawn is?

[shell heath]

So I need to make a widget for all the cards individually and then create another widget with them all in it?

[odd ember]

no that would be insane

[dusk basin]

@dawn gazelle

[odd ember]

you create widget template for your card

[unique harness]

Each card is represented by the Inventory Slot widget I was talking about earlier

which accepts your card struct to initialize the image and other relevant data

[dawn gazelle]

You have BP_Portal set as your Default Pawn in your game mode?

[dusk basin]

@dawn gazelle

[odd ember]

@shell heath this is the important part. but also, you can format that widget to be setup as a card, or have a child widget do that for you

if you have certain card layouts that you want to have for instance

the cool thing about widgets is

as soon as you make one

you can find it in the layout panel as an option for other widgets

so you can keep nesting widgets

then, each card will be an instance of said template, each with individual data

[shell heath]

Okay, so from the beginning.

New Project -> Delete all folders

What should I do first?

[odd ember]

I wouldn't delete all folders, although probably epic didn't think about including a board game template

the plebs

[vast lion]

Are SceneComponents as actor roots expensive?

[odd ember]

more expensive than roots without scenes but not ridiculously so

wait never mind

[dawn gazelle]

Just to make sure... You had it set up something like this, yea?

[odd ember]

scene is the cheapest

you can get for an actor

as a root

actor components are cheaper

but not rootable

[vast lion]

Right but if I have a skeletal component as a root vs as a child of a scene component root

How bad is that?

[unique harness]

probably shouldn't do that. You have a widget, BP_Inventory

[dusk basin]

yes

[unique harness]

all it is is a scroll box

then you have BP_Card

which is just an image

[odd ember]

is there any actual skeleton enabled for it?

[unique harness]

@shell heath in BP_Card you have a Card Variable,

[shell heath]

Well when I start a blank I just start with a floor and some camera/light options

[vast lion]

@odd ember yes

[dawn gazelle]

You must have some logic elsewhere that is making your player possess a different pawn.

[unique harness]

@shell heath BP_Inventory has a list of BP_Card widgets

[dusk basin]

@dawn gazelle are you sure the portal does not need to be reparented

[odd ember]

then yes. but keep in mind component cost isn't relevant to e.g. searching. so it's the same cost whether you have it as a root compared to in your component hierarchy

[unique harness]

@shell heath BP_Inventory has an initialize function that accepts a list of cards to show and this would be the logic.

[unborn maple]

thanks dirtsleeper that work

[dawn gazelle]

Yep, it's fine to be a spectator pawn as it inherits from pawn.

[unique harness]

@unborn maple no problem, glad it did

[split barn]

Is there a way to access objects outside of the blueprint? I want to modify the rotation of an object outside my blueprint but idk how to.

[dawn gazelle]

What's happening is your controlled pawn that your getting is not a BP_Portal.

It's a BP_MenuSpawnner

Which obviously cannot be the parent of your BP_Portal as your BP_Portal is parented to SpectatorPawn.

So the cast will fail.

[dusk basin]

but it needs to be a BP_menuspawnner otherwise my mainmenu will be broken

[unique harness]

@shell heath BP_Card initializes image based on card passed in when created.

[dusk basin]

so a reparent would be needed in this case

[odd ember]

would still recommend doing a card layout in widget instead of just parsing an image

[dawn gazelle]

No, your player controller is getting possessed into the BP_MenuSpawnner.

[odd ember]

as in, as a separate widget

[unique harness]

yes, i was just trying to make it as simple as possible

[shell heath]

How did BP_Inventory become BP_Card?

[unique harness]

it didn't, there are two widgets

[shell heath]

Ok

[dawn gazelle]

if you're saying your controlled pawn is supposed to be a BP_Portal, (as your screenshots indicate) and that is what you want your player controller to possess, then why is your player controller possessing a BP_MenuSpawnner?

[odd ember]

it should

are you by chance tryng to use it on a camera actor?
