blueprint

[gentle urchin]

^exactly

If the card is spawned it means it has been picked

no reason to check if ID picked is the ID that got spawned

[marble echo]

so i'd need some way to create the card based on the ID drawn, and all the effects would go after a on Created event?

[barren flower]

But in answer to your question, cast to the deck that created it, which should be a reference set on its spawn, and get its array of drawn card ID's, and then see if any match your own ID

Yeah, so do this

[marble echo]

so it wont be able to get that info from the card ID stored from the instigator?

[gentle urchin]

I'd still prefer going for a master_card class in this scenario and set it up that way. Should be really clean and simple to create child actors with overriding "play card" events etc

[marble echo]

as in, this wont work

[gentle urchin]

You can make it work, but it doesnt make much sense for it to be like that in the first place

[marble echo]

hmm i see

[barren flower]

Have the deck spawn a card, this card will just be a default, empty broken card. Have the deck, with its reference to its newly created card, then fill in all the relevant variables in the card

[gentle urchin]

Problem occurs when this is a special play card

[barren flower]

https://i.pinimg.com/originals/1d/16/3d/1d163d8c31d477a866e1ac3cc669595d.jpg

Spawn this

[gentle urchin]

playing this card has X effect

[barren flower]

Have the deck then send all this

[gentle urchin]

Unless ofcourse you wanna make yet another class for effects

[barren flower]

have the deck then add that card ID to an array variable it has

[marble echo]

this isnt a traditional ccg type game, cards are more like events in which the player chooses what to do

but prob doesnt matter

[barren flower]

Same thing tho

Cards should just be cards

[gentle urchin]

And the effect of the card?

separate class?

[barren flower]

If the card is then chosen, have the card send that information through and interface to whatever is running the logic

[marble echo]

i think i get you

just need to figure out how to pull the IDs or something then

[gentle urchin]

Doesnt sound very flexible/expandable if there's a common place for all this logic

Perhaps I'm overthinking the effects ofcourse, if its all just stat changes then it doesnt matter

[marble echo]

thats why i wanted each card to be a separate blueprint

[gentle urchin]

but as I understood you there could be very different effects on the cards

[marble echo]

dunno if this helps

[gentle urchin]

Is it just attribute / stat changes?

[marble echo]

this is what im trying to do

[marble echo]

pretty much yeah

and stuff that changes the widgets text

[gentle urchin]

then ID's and DB lookups is all you'd ever need....

[barren flower]

yeah okay so

Do you know what an array is? Basically just a dynamic list

dont be insulted people come in all levels of skill here, fyi

so

your game logic should be running all of that stuff

[marble echo]

yeah, the deck is an array

[barren flower]

Player clicks card

[marble echo]

im still understanding them tbh but yeah

[barren flower]

that should then shoot an event of card clicked to the game logic, and carry all the cards information

+1 to health and everything

[marble echo]

this is the deck BP

this is the old way I did the cards which i dont think is any good

[barren flower]

Okay so you arent getting what im saying, hang on

You are trying to have the card run all the logic of what the card does

which sounds like it makes sense, to a player

but, all the card really needs to do is be a glorified button, with its effects stored inside

[marble echo]

i wanted it to be easy to be able to create cards in its contained bp, especially for other people to add them and understand it, and i thought separate bps would be the way to go tbh

[barren flower]

The game logic blueprint should receive information from a card, and process it, not the other way around

[marble echo]

i hate to ask this but... why?

[barren flower]

Depends how flexible you want the cards to be, what exactly they change

Okay

So

Lets say some of the cards add 10 health to all the villagers in a city, and some of the cards take away 10 health

All you actually, under the hood, need to do, is have the game logic add the amount of health on the card to the villagers

you just need the logic to read the card

the card can just be a collection of variables. That also lets you add and change cards trivially

just create a list of everything you want the cards to possibly effect, and send whats relevant when selected

[gentle urchin]

Thats the expandable part.

If you keep the logic in the cards, you can do whatever magic you want. Why bother passing it to another bp/actor/object, for only to find it constraining you ?

[jade sedge]

I had create a grid inventory, and now I like to charge. But I don't know how to get items of the grid and later load it. Because isn't a normall inventory.

Basically I like to get items of the grid in a array , save and load it. But i don't know how because the base are item objects

[barren flower]

Think of it like an ATM, you dont have your bank card tell the machine what to do, the machine just reads the card, checks to see if the money you want is there, removes some amount from the card and dispenses cash. The card is totally passive, the machine does all the proccesssing

[marble echo]

I guess i just dont understand where all this information comes from?

[gentle urchin]

Thats a very generic analogy, with very fixed amount of variations to it

[marble echo]

unless i make a huge bp with all of it in

which is going to be awful to edit later

[gentle urchin]

Imagine trying to make Heartstone with a singular place for the game logic

New card pack? Lets expand our already messy switch on INT kinda thing

What's the benefit from localizing it that way ?

[barren flower]

Thats what I said, you need to clarify just what you want this system to be able to do

Hearthstone is very simple to do with that system.

https://cdn.hearthstonetopdecks.com/wp-content/uploads/2015/08/acidmaw-hd-300x429.png

This card is a collection of varibles

Cardname: Acidmaw
7 Blue I dunno i dont play hearthstone
4 orange
2 red

And a trigger to do [destroy] on [enemy damage]

If you want people to totally create dynamic stuff, like you never even considered the ability to scan the board for enemy damage, then maybe you need an individual blueprint for each card, but I dont see that system being remotely workable, just generating totally new mechanics, games dont work like that

[barren flower]

The answer to this question is probably a CSV file? Literally just an excel spreadsheet of card stats, very easy to modify

[gentle urchin]

It would definitely break the game if one allowed game mods to alter established effects or even worse, create new ones

[marble echo]

im not talking about mods for mechanics etc, but we have a team of 3 and i want card creation to be smooth for them

as in just changing and ID number and adding it to the array

[gentle urchin]

well if its all stats up and down , then csv/db should work fine

[barren flower]

Variables, csv, literally just change numbers on a spreadsheet

[marble echo]

hmm ok

[gentle urchin]

all they'd need to do is add a row in excel, and ^change the numbers

[marble echo]

ill try figure it out

[gentle urchin]

and whatever displaytext is needed

[hollow gorge]

This isn't directly related to your current blueprint problem but I recommend reading this to better understand the concepts behind object oriented programming: https://www.geeksforgeeks.org/object-oriented-programming-in-cpp/
Understanding the basics to OOP principles may help your future thought process when working in unreal.
I only mentioned it because I saw your question to "Why work like that"

[marble echo]

alright thanks, ill check that out

[hollow gorge]

this would be be the answer why you should approach the problem the way as proposed previously

[barren flower]

But as I was saying, when that card is played, it should send all those things to the game logic, and it should.. I dunno I dont play hearthstone, deduct 7 blue for the cast if you have it? Deal 4 [damage] it looks like yellow is, to its target card, and survive 2 [hits]? Then it should also load the [enemy damage] tree and [destroy] [target]

[gentle urchin]

costs 7 mana to play, deals 4 damage and has 2 hitpoints ^ spot on🙂

[barren flower]

Right, so none of that should be logic in the card itself. That should either be running in the players logic or the tables logic

[marble echo]

so you'd have the player hold all the possible variable additions / subtractions?

[barren flower]

No

Id have the player hold the system of what to do with these things

The deck should load a CSV with all the different cards you have

[marble echo]

but where does the information come from? what do display as text and what variables to change?

[icy dragon]

I felt like the setup can be summed up in a turn based Japanese RPG

[marble echo]

right. ill look into csv

thanks for putting up with the questions btw

[barren flower]

Its just excel spreadsheet, unread can import them as a glorified array

thats totally fine

so like

road rules, right?

Do you store every single possible combination of road ever

do you know what the turnpike in albakurky looks like?

No, you have simple rules

if red light stop

turn left on green

The logic does that, but it just gets its information for decisions based on the variables stored in the cards

Have it start off with do damage, for instace. Get the yellow number from the card and do 4, apparently. Receive damage, is the attackers damage greater than 2? Then destroy the card. That sort of thing. Create a card system

[marble echo]

maybe this helps understand what im trying to do with it

[barren flower]

Then load something like this

https://i.imgur.com/t2YAdwr.png

Okay so you arent really creating a card system, you are creating a choose your own adventure decision tree

[marble echo]

im def trying to create a card system. i guess im just trying to bend my mind around these limitations

well, both really

[icy dragon]

That sounds lot like Dungeons & Dragons

[barren flower]

Wait wait, yeah you are

looking at the options

Yeah so

okay

[marble echo]

it has deckbuilding elements, as in cards are added during play

[barren flower]

All the flavor text should be stored as a string

[marble echo]

but cards is the best way i can describe it i guess

[barren flower]

and the like, gain gold, loose health, all that

that should be systematized

Every card should have a variable for how much gold should change

every card for how much health

that doesnt have to be displayed to the player

but the system should add 0 gold and -2 health

Is this the right place to ask about Widget Interaction Component and 3D Widget Components since this is for UI as well? (if not lmk)

I have a Widget Interaction Component that should be set up correctly according to several fourm posts.

Trace Channel: Visibility
Interaction Distance: 1500 (Note, widget is less 500 distance)
Interaction Source: World
Enable Hit Testing: True

And my actual widget located in the world:

Space: World
Geometry Mode: Plane
Receive Hardware Input: False
Blend Mode: Transparent
Visible: True```

Yet for some reason, my widget won't register user's input at all? My widget contains a button that checks for `OnClick` and `OnHovered` and neither trigger.

(Attached is the code checking for the reaction, and the code giving the reaction.)

[marble echo]

yeah, thats what i want ideally

its just elaborate way of numbers changing

[barren flower]

yes, it is

So again, you cards should just be storing this as a struct

[icy dragon]

Seems like redirecting him here is not in a good timing
I have no idea with world space widget interaction...

[barren flower]

and your game logic should do all the things one by one in the struct when selected

[marble echo]

structs are basically global variables it seems?

[barren flower]

I dont know anything about widgets, but if you are trying to do on click is Receive Hardware Input: False this not a problem?

Structs are a type of data, a structure of data, basically collections of variables

[marble echo]

it seems like i need to look into csvs to make this work then

ah i see

[marble echo]

that seems useful

[wind void]

it used to be on. But while googling, I saw a video explain that it's for ACTUAL hardware, otherwise if set to false, it's for imaginary hardware. And they made it work with it off, and it's defaults to false as well.

[marble echo]

i think the biggest barrier for me atm is just trying to figure out how to have each card hold this information and how to access it

[barren flower]

Laterally a generic card blueprint

with variables

Hi, im using the mesh merge example:https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/WorkingwithModularCharacters/
But my merged mesh doesn't simulate physics although all the added meshes have physics. as you can see my tank is hovering.

#legacy-physics, the channel.
Someone there might know more about it, as runtime skelmesh merge has little to do with BPs.

Question: If you use stat game in the console and you see BlueprintTime taking up a lot of time. Is there any way to drill into "BlueprintTime" further to see what is taking up so much time?

[icy dragon]

You can use Unreal Insights for CPU thread profiling. BP calls included

[brave quest]

I didnt' realize BP calls were in there. Thanks

[hollow gorge]

Just wanted to say thanks for this recommendation.
I really like the modular approach through components. 🙂

[foggy junco]

Is there a blueprint interface for nanite?

[charred flint]

Im trying to make a multiple choice option and have a user being redirected to a web page based on a specific answer he chooses.

I got this blue print done so far but miss the idea on how to get the multiple question involved in this

What im trying to do exactly is have the user click on something, then a question pops up with 2 answers, and the choice the user makes decides the interaction

[icy dragon]

ngl launching URL/webpage as a game mechanic seem dubious

You can use event dispatchers and have the question widget bind the response events for the options.

[charred flint]

Well let me explain the purpose of this first before you think its something sketchy

[wind void]

Use a widget? Just have multible buttons and depending on which one is clicked, runs whatever option.

[charred flint]

What we are trying to make is an interactive map (web based) in unreal engine and have users walk around, get info on certain topics or be redirected to a certain webpage

[charred flint]

hmm not a bad idea thanks!

[next robin]

Hey! I'm currently stuck at this. It's essentially a simple actor with a box collider, when a character begins overlap I want it to type in "success" (for testing reasons, in reality I want it to cast to another actor and run a custom event) but it's failing every time. Is this because of the connection with "Other Player"? I'm unsure at this point, would love any help

[hollow gorge]

Does it have to be a on component event overlap? Could try with "Event ActorBeginOverlap" instead and see if that works

[dawn gazelle]

OtherActor is in reference to the Actor that caused the overlap to trigger. I think maybe you mean to cast to your character class rather than the Parents_Door class?

[west wigeon]

is it better to freeze 100 objects(all invisible) or just destroy and respawn them

[tawdry surge]

Depends what they are. Pry best to use a particle system so you can use object pooling

[safe musk]

Guys, what is wrong with this timeline ? I set the hero location to start and set goal position, but when timeline do the lerp (vector) , the character don't stop in the right location ....

[dark crow]

Show Goal Vector

[solemn musk]

hello is there a possible way for me to generate and read from a text file
I wanted to make a file that stores random names on each line of the file and have the game chose a random one from any line

[dark crow]

Do you actually need it to be a text file? Cause you could go for a normal SaveGame too

Only use case I see would be modifying it externally with an actual text file

If you reeaaaally want a text file

Look into FFileHelper and FPlatformFileManager

You would need to write a custom C++ Lib tho

[dawn gazelle]

If you don't care to load it at runtime, you can import csv into a data table.

[solemn musk]

Ill just do a csv import, thank you

[novel rock]

How do i...

[main lake]

How to make a binded Event not fire every frame but only when I call it please ?

[dawn gazelle]

Don't call it on tick?

Or is this for some bindings you've done in UI?

[main lake]

I'm not calling it on Tick

This "IsMinigame" event is called every frame somehow

[dawn gazelle]

What calls Hour Chgnged Dispatcher

[dawn gazelle]

What calls to set your hours variable?

[main lake]

my function Calculate Hours

[dawn gazelle]

What calls calculate hours?

[main lake]

my timer

[dawn gazelle]

How often is the timer ticking?

[main lake]

depends on the variable ratio

[dawn gazelle]

Point being, whenever your timer is ticking, it's going to be calling that dispatcher.

[main lake]

how to make it only call that when the Hours variable change ?

[dawn gazelle]

Don't call it there.

You have to figure out where to put it.

[main lake]

I thought OnRepHours is called only when "Hours" variable changes

[dawn gazelle]

We've already had this discussion. #blueprint message

[main lake]

How to fix it ?

[novel rock]

how do i get a class from an array?

[dawn gazelle]

Probably by not converting to float. #blueprint message

[main lake]

I think I already tried that and didn't work that's why I got back to floats

[tight pollen]

are widget animations taking performance away?

[main lake]

How do you have those straight lines 😮

[dawn gazelle]

It's a paid plugin on the marketplace. Electronic Nodes.

[main lake]

argh, how much ?

[white field]

good reasons to use Maps instead of Arrays? seems like an extra layer of fluff

[white field]

get a reference to an array entry first then lookup the class

[mental trellis]

Maps are good when you want to search quickly by ID

[white field]

you can make the wires straight without a plugin afaik

[mental trellis]

They use hash buckets and such.

[white field]

hmm

isn't a Map just essentially two coordinated Arrays?

[mental trellis]

Yes, but it has the ability to quickly look up a key to find a data pair. With a regular array you'd have to search the array one by one until you find it.

[white field]

via the hash buckets

interesting

thanks

actually, on the same theme.. if I want a bunch of weapon stats, is there a better container than manually managing a bunch of individual arrays?

[dawn gazelle]

Data Tables/Data Assets

[white field]

not a Set?

ah Sets are all the same variable type I guess eh..

[main lake]

It keeps printing every time the minutes change (so multiple times per second) instead of when the hours change

[main lake]

?

[dawn gazelle]

Have you changed to using integers instead of floats for calculating the hour?

[dawn gazelle]

Print the output directly after the modulo, and again after your hour set.

See what values you're getting.

[main lake]

after the conversio nnode from int to float or before ?

[dawn gazelle]

Before

[white field]

are those tables read-only?

[dawn gazelle]

At runtime, yes. You can instantiate the values from the table into an actor and manipulate the values from there.

[dawn gazelle]

ok, and what about after the float?

[white field]

into a data table actor? or into an actor with corresponding variables to fill?

[dawn gazelle]

Into an actor with corresponding variables to fill.

Data Table can thereby act as a base where all your items can exist just as data. Then when you spawn your weapons, you can just use a base weapon actor, and feed in the values as needed.

[white field]

any way to automate the creation of those variables from within bp land?

[dawn gazelle]

You're going to be using a structure to create the datatable. You can juse create a variable of type <that struct>

[white field]

hmm

ok, thanks very much

[dawn gazelle]

So that's looking good there at least. Value isn't jumping around all over the place. Still getting it calling the event dispatcher though... Are you manipulating the hours variable anywhere else?

[main lake]

To check if it's night or not

[dawn gazelle]

Ok so actually what I see in the above image as well is that it's only the sever calling the dispatcher. So the OnRep is still firing on the server, but not on the client and I tested on my end and I see the same behaviour with an OnRep variable. I guess that means you'll need to put a branch that checks if the hour is != the % output and if true set the hour.

[white field]

so you can't just create a table from within bp?

I don't really want to need to go out to a separate editor just for CSV

possibly over thinking my requirements but also just trying to understand the options and upsides/downsides

[dawn gazelle]

Once you've created a data table you can modify its contents, just not at run time.

CSV is helpful if you have a lot of data to enter in all at once, otherwise you'll be manually setting all those fields yourself.

[white field]

hmm ok that helps, thank you 🙂

[sharp rapids]

For some reason, data asset ref is not working in Standalone mode?
The Texture references are blank

First pic is In editor

Second is in Standalone

Sometimes, both textures don't appear in Standalone, but sometimes one of them does

[lofty ravine]

Hello I have a level selector with a combobox that works well on client side I am trying to expand it too server side anybody know how i can do that

[devout latch]

How are you loading them?

[sharp rapids]

I have references to Data Assets stored in an array, I loop through them, get the texture variable in them and set it as the image in UMG

This is the array

Checking the references, it seems one of them is just ...not there?

[devout latch]

What if you make both of them the one that works?

just as a test

[sharp rapids]

It works

[devout latch]

Are you doing any async calls in your for loop?

I remember having a similar problem awhile back because I wasn't handling my loops correctly with async calls.

[sharp rapids]

I have a For Each loop, but not any async calls

[dusk ember]

https://www.youtube.com/watch?v=94HpeqlgKAs&list=PL4G2bSPE_8um-3MIHOTwFwjWZdWO24S9O&index=12 so i used this tutorial and everything works, except for the fact that when i change the weapon being used in either slot, it uses the variables from the previous weapon. anyone know how to fix this? (i have a thought but i want to know what you guys think is a good solution)

[reef marsh]

I have my character spawning a projectile for the basic attack in a TPS. However, the BaseAimRotation from the pawn is a bit low based on the location of my camera/player aimpoint. I tried breaking the rotation out and then adding to the Z axis but that doesn't seem to have any real effect.. What might I be doing wrong or how should I approach it better?

[devout latch]

Can you load the pickaxe outside the for each loop? Hardcode it? As a test?

If you could show the blueprint, that would help.

[sharp rapids]

So, I loaded the Pickaxe later, And now both work?

The later one as well as the one in the loop, both work now 🤷‍♂️

I'm confused

[devout latch]

Yeah, that makes no sense... I wonder if it is something in the loop, though..

My issue is that it was going to the next item in the loop before it was actually loaded.

[sharp rapids]

Here's the BP
https://blueprintue.com/blueprint/vqx5ywsu/

[sharp rapids]

The bottom disconnected part is the hardcoded pickaxe

[lofty ravine]

can someone help me on changing my level on a combo box its only affected to client and not server please

[devout latch]

should there be an item amount to craft on all entries?

[sharp rapids]

Yes

[devout latch]

ok, so it didn't even make it to that code in the loop? Not even in the editor play?

[dawn gazelle]

This is on a widget?

[lofty ravine]

yeah

[dawn gazelle]

Are you replicating the change to the server through your player controller?

[lofty ravine]

i am trying too

but idk how i would go as of that

because i tried doing something similar

and just cant get it to work

i tried even doing a server command cuz thats all i found online

[dawn gazelle]

So with the combo box you're selecting the level, and then clicking a button to execute?

[lofty ravine]

yes

[sharp rapids]

It did. It makes it to the end.
Just that the texture ref does not seem to load

[dawn gazelle]

Can you show what you have currently for the button clicked event?

[lofty ravine]

yeah i will show you the code

[sharp rapids]

I have nested Data Asset references, might that be the reason?
I reference the Crafting Data Asset which references the Items Data Asset. The Items Data Asset is where I get the textures.

[dawn gazelle]

That's basically an infinite loop there...

But anyway... The idea being if you want the entire server to move to the new level, you need to be running on the server. Change your "Change Level" event to "Run On Server". From there, you should be able to do whatever sever travel you need to do.

Button Click > Executes On Server Event on Player Controller > Server does what it needs to do.

You'd also need to include what level you want to switch to on the event if you want the player to be able to tell the server what level to change to.

[lofty ravine]

ok tried doing that but it says infinite loop

[dawn gazelle]

This is an infinite loop.

Get rid of the blue one.

[patent plover]

I am following a tutorial. In that tutorial, I found this comment. I know how to make this in c#, as thats what I did in unity, but idk blueprint. Can someone tell me how to implement the comment in this code?

Instead of delaying 1 second each time before you regenerate which makes for a choppy regen I suggest multiplying the delta seconds times the amount you want to regen and adding that to the armor, much smoother

Here is the code:

most stuff is from the tutorial, and I have made some improvements myself

[lofty ravine]

what do i change to it

[patent plover]

I think they said to get rid of the blue node

[patent plover]

.

[brazen pike]

Delta seconds out of the event tick multiplied by the increase rate for health (or amour I guess)

[patent plover]

oh, thank you!

[lofty ravine]

yeah but do i leave it like that

[patent plover]

ig

[lofty ravine]

ok i left it liek that and nothing changed

[devout latch]

I don't think that's the case. Can you get the image data asset from the actual array element in the for each loop instead of the temp variable you created? It looks like this is what you do in the bottom code that works.

It should be the same but that's one thing thats different.

[lofty ravine]

i deleted this

[dawn gazelle]

Get rid of this node as well. This will make the client move to another level before telling the server to move.

This node is where you want to have your server do the move. There is commands to move the server and all connected clients, I just don't know them myself, but that is where you'd want to execute it.

[lofty ravine]

ok thanks for the help

[dire storm]

I'm making a button blueprint in which I can choose different type of Collision shapes (Selectable in the the child blueprint from editor) how do I make it ?

[sharp rapids]

Well since I added that Hardcoded texture, both widgets are working. I removed the code and they're still working. I closed and reopened the editor to see what would happen and they're still working.
I have no idea 🤷‍♂️
But I'll definitely try that If it happens again.
I'm thinking it was a bug, because it happened to both widgets, then only to one widget and now to none of them. The code is exactly the same as it was before and it works now.

[devout latch]

That's good to hear! I hate when that happens, though!

[sharp rapids]

Thanks for the help 👍

[devout latch]

No prob

[high sapphire]

Weird, it looks like it isn't finding the row. I guess that means I set something up incorrectly?

[gentle urchin]

Correct

Wrong row name usually

Print the row name variable

And compare

Im a bit curious after yesterdays discussion about where to put game logic. Is it some general practice to localize it into fewer larger classes that handles everything logic wise, and leave the actual ingame actors as pure player representation of data? (As in they hold no logic at all)

Whats the benefit of this, if so? And whats the drawbacks of having the logic spread across their "owning" classes?

[rough cedar]

Anyone have a tutorial link or something to getting the player to have a cursor point independently at stuff while moving. But not turn the camera or character? Also this has to work on both mouse and gamepad. I built one using "convert mouse location to world space" and it worked but only for a mouse, which doesnt help me.

[sharp rapids]

are you talking about having base classes?

[patent plover]

how to pass parameters to a blueprint function?

by using float variables?

[sharp rapids]

You plug them in?

[patent plover]

yeah but for example I have this func 'takeDamage' then how to add the space to plug them in? in c you do it with

Myfunc(float parameter)
{  
  //code here
}

so thats how you pass values

this is my function node

[sharp rapids]

Select your function (Name Pin) and in the 'Details' panel you will see Inputs and Outputs

[patent plover]

oh ok thank you

[sharp rapids]

You'll need to open the function

And Select the purple name node

[patent plover]

uh, and how to use a simple float? like i wanna add 0.05 as damage so can I do it without making a variable?

[sharp rapids]

What do you want to add to?

[patent plover]

nvm, sorry

[sharp rapids]

There's an 'Add' node you can use

[patent plover]

I figured it out

[tight schooner]

Not a professional. But I can add that... I recall Epic saying how they use a lot of "data only blueprints" in Fortnite. Thinking about how that game world is full of objects that generally have common modes of interaction (use a weapon or tool to damage it and convert it to resources, etc.) it seems to make sense. The difference between a tree, brick wall or rusted out car body may as well be a bunch if parameters. I also wonder if part of the rationale is to more strictly define areas of responsibility in a large team

[gentle urchin]

If that was a reference to this, it'd still be a master class involved for this, containing the logic

And I agree, that it would make sense to have some "damagable actor" master class, and use child classes with data only to make the differet types of objects, and what resources they provide

This is not the gist i got from yesterdays discussion about having some "central place" for the game logic tho. It sounded like having all the logic for damaging any object should be contained in a single class which is unrelated to the object in question

Appreciate the reply btw 🙂

[tight schooner]

I didn't see the discussion so idk the context. What would the central place be?

I'll say that recently I've refactored (or whatever the correct term is) my current project so that all things related to damage-able objects are contained within a component that I can slap on a BP. All things related to enemy movement are a class hierarchy of components, etc. Things that are truly universal go into base actor classes. My goal was to make actor BP classes that would actually go/spawn into the world as thin and data-only-like as I could make them and that's worked out for me so far.

The downside that comes to mind is some of the base actor/component classes can get complex, handling a lot of possible use cases. (Say, enemies that have invincible bits, or enemies that have groups of components with different health pools, etc)

[gentle urchin]

Makes very much sense to me for it to be components, and to be stuck onto the actor you'd want to support the components functionality. I suppose this could mean a bunch of redundant code existing on every instance of the actor, instead of one singleton handling the damage functionality (with components only sending data to it), but that's the best reason i could think of ...

Yeah I've experienced some of the complexity myself aswell, having to provide functions for things you didnt even plan to provide functions for etc.

There's also options of sparse class data for saving some potential memory, but for mortals it feels like a stretch going that far (?), when the bottleneck likely resides in other areas than memory footprint ..

[tight schooner]

I've always wondered if code memory footprint is a theoretical consideration or an actual one for the systems that Unreal Engine 4 supports

[gentle urchin]

Yeah I'm not sure really. Would be interesting to know

[dusk nymph]

how can i get variables from a variable actor i will set on the event graph

[trim matrix]

Hey guys so im working on my multiplayer project but right now i have small glitches that i need help with
so the problem is : Character won't select so I have to press the button 2 times until it actually gets selected and spawns
not sure if problem is in this blueprint

[dusk nymph]

did you mean this ? the problem is the held item may not be the weapon1 for example

[graceful holly]

how can I clamp the falling velocity of a character? using the character movement component

[dusk nymph]

meaning that I have to create child blueprint class right ?

thank you very much

[charred flint]

I have made this teleport which works fine,

I am only wondering on how I can make the left end of the log only respond when being on that side (to teleport to the right) and vice versa for the other side if the player is on the right side of the log that it has to click on the right side to go to the left.

Most prefered even to have the player walk up to the log first.

Anyone has any suggestions?

[spice smelt]

Is there a workaround to call an editor utility blueprint actor function from a regular actor?

[gentle urchin]

Could you simply check players location relqtive to the log ?

Make a unit direction vector from log to player, dot product with the "forward" vector of the log, and determine from that which side they are currently on?

[spice smelt]

Epic's own virtual camera does it

[charred flint]

Sounds like a good idea I will try to find a tutorial for this ( I know alot about unreal engine but just always had this on and off relationship with the software haha) Sounds like a good suggestion! Another thing I was thinking was add a very small mesh on top of the logs on both end and add the teleport to that object instead, but then I would still need to figure out how I can avoid it to trigger when a player is at segment A to not have it activate on segment B)

I guess a bit like the way runescape handles those kind of click to teleport interactions

[fervent kelp]

hi guys, is it possible to add sockets on static mesh from blueprint . i have location vector array from vertices but can't find add/set sockets function in default? I know, it will be added manually from editor with "add socket" feature but is there a way to manipulate (create /add/delete/ transform) socket from BP at runtime?

[odd ember]

I don't think so since sockets are pertaining to a mesh. you could try and see if mesh operations are available. otherwise I'd use scene components for this

[sharp rapids]

Can you change the type of Rows in a Data Table?

Instead of FNames, maybe Gameplay Tags?

[odd ember]

only by changing the struct the table is based on

or do you mean the initial name column?

[sharp rapids]

this

[odd ember]

not in BP no

keep in mind this would also break stuff like the GetDataTableRows nodes

[sharp rapids]

i see

[charred flint]

I dont suppose we can crop meshes can we?

[icy dragon]

If you don't use runtime procedural meshes, no.

You could fake it with world aligned opacity mask in material

[graceful holly]

how can I clamp the falling velocity of a character? using the character movement component

[charred flint]

hmmm thats still to technical for me at this stage im afraid

What I have tried now is adding 2 components on the tree log and have them reverse teleport but one thing im really not sure is how can I make this work only when its within a X amount of distance from user? As right now if you click on it from a distance it will just teleport and also doesnt care on which island it is

Teleport currently looks like this:

[wicked osprey]

Guys, I have a controversial question. Which is better to use cast or interface? For example, I have 15 widgets, each of which should have a cast on a character. Wouldn't it be better to create 1 interface that will be called on the event construct on the main widget and run on all 15 widgets?

[restive oracle]

Apologies not sure whether to put this in the BP or CPP channel

[odd ember]

cast

you can save a cast variable

[spice smelt]

"Add component by class" adds a component to an actor. If it's a scene component it fets added to the root.
How do I add a scene component by class as child of another scene component inside the actor?

[odd ember]

or pass it to the widgets individually

and I would recommend not to think of interfaces as the solutions to problems

interfaces solve one very specific problem

and that is it

[sharp fox]

Hey, anyone have idea how to make a burger creating?

[high ocean]

why does having a widget displayed prevents [Event Keyboard "x"] from executing? I keep getting stuck on the silliest of things fml...
Context: Trying to implement a simple "esc" key (now bound to a letter) that would always call the ">>remove from parent" code of the last widget added to the viewport. The Controller holds an array of all open widgets, picks up the last added one and calls it's close code.

[sharp fox]

#umg

[charred flint]

We have so much people asking questions if someone would earn by answering he could make a living out of it 😛

[wicked osprey]

For every widget?

[high ocean]

@sharp foxnot really, no...

[odd ember]

you can have a widget hierarchy

[sharp fox]

what not really

[high ocean]

@sharp foxIt's a controller question rather than a umg one, so no, the channel is fine 😒

[sharp fox]

ok ok

[rapid bronze]

hi. what delta(rotator) node do? what the meaning of normalized A-B

[high ocean]

@rapid bronzehttps://www.youtube.com/watch?v=c5dPBJfMpKI&ab_channel=MathewWadstein
https://www.youtube.com/watch?v=GyJVYB3IzGA&ab_channel=MathewWadstein

[sharp fox]

Hey, anyone know how to make an burger making system? Like, you need to place bread first, then something and then something to make it work

[odd ember]

an array of actors and something that checks that array for consistency

so bun actor has to be first, not lettuce actor etc.

[sharp fox]

ok

[wicked osprey]

Widgets can't be inherited, can they?

[earnest tangle]

Okay weird issue... Why would this cause "Accessed None trying to read property K2Node_Event_DamageCauser"?

[sharp fox]

is there a node that can check it?

[earnest tangle]

Even if DamageCauser is None, this should just forward the None value into the function call so I have no clue why it's doing that here...

[odd ember]

no it's logic you have to write yourself

[sharp fox]

but im a begginer

[odd ember]

okay. well the good news is that engine doesn't really care what skill you are at, it still needs the same logic

[sharp fox]

but im in 8th grade bruh, im 13 yo

[rapid bronze]

Thank you. But they did not help. my question is about delta(rotator) node.

[high ocean]

@rapid bronzeoh, i'll thought you'd figure from the two vids

The description of the node is pretty self explanatory - it normalizes 0-360 to 0-1 (if I remember correctly)

[rapid bronze]

its same as normalized in vector?

[odd ember]

ask a teacher?

[rapid bronze]

i cant get normalized in this node

[high ocean]

@rapid bronzehttps://www.youtube.com/watch?v=8RPk3zldqAA&ab_channel=RATSGAME

[rapid bronze]

oh i get it

thank you

[high ocean]

@rapid bronzenp 🙂 gl!

[earnest tangle]

Oh wait I'm blind, it's using GetActorLocation on DamageCauser which obviously would be causing that error... the debugger was suggesting it was the function call node lol

@odd ember are you trying to be difficult on purpose? :P

He asked a valid question

[sharp fox]

bro, my Informatics teacher don't know how to use word, and you are telling me to ask him for help

i live in poland

[earnest tangle]

Your question about the burger thing is kind of broad, it can be done in very many different ways depending on how your game works

That makes it kind of difficult to answer

[wicked osprey]

I can't do widget hierarchy, can I?

[gentle urchin]

Never tried runescape so wouldnt know how they do it. But if its ment to be something like clicking the mesh ports you to the opposite side, then my suggestion would work pretty nicely :)

As in one side would be < 0 and the other side would be > 0 as dot product value

[odd ember]

why not? a widget is a class just like everything else

[odd ember]

well I don't know what you expect of me. I'm not your teacher

I would expect if you get an assignment to do stuff you can also ask for help about doing stuff

[earnest tangle]

Why are you being so hard on him? It's just some kid trying to figure shit out

[odd ember]

I'm not being hard on them? I just think there's a different expectation from them than I can support them with

I've given them the way to do it

[wicked osprey]

No, widget class can't have child class

[odd ember]

🤔

[gentle urchin]

Since when?

Im using child widgets in 4.27 atleast

[earnest tangle]

Yeah and they pretty clearly said they didn't really understand how to do it from your high level explanation, after which you were basically just talking down to them

If you don't feel like explaining it in more detail that's fine, but you know you can just say so

[odd ember]

it wasn't a high level explanation. I told them keywords that are available in the engine

in blueprints even

an array exists in blueprints

you can create logic to check order

[wicked osprey]

Damn, why didn't they add a button to create a child class☹️

[odd ember]

I'm also not at all talking down to them. I'm just not in a position to be a teacher for them

which I think is fair

[gentle urchin]

But there is ? In the content explorer, right click the parent widget -> create child?

[odd ember]

it is true you cannot inherit from UWidget in BP, but you can inherit from UUserWidget

[gentle urchin]

Huuh

[wicked osprey]

Hmm, but it turns out I still have to do casts to all widget, don't I?

[gentle urchin]

Not really, as long as your ref is of the parent type and the parent type has all implementations you need

[odd ember]

I think you're putting a level of expectancy here on me (and people who help out here) that isn't really valid. I'm trying to help with what I can. I can't sit down and write a system for someone

[wicked osprey]

Aaaaaaah, i can do cast in main widget and create child widgeeeett

Thanks guys

[odd ember]

bingo

[earnest tangle]

I'm not expecting you to do so, I'm just saying you can just say so instead of arguing with them about how you think they should be asking a teacher about it instead of asking about it here - which already is a pretty unfair assumption that a 13 year old even has a teacher who even knows what unreal is lol

[odd ember]

it sounds like they're doing it for class. I'm giving constructive suggestions for what they could do

instead of just saying "lol figure it out yourself"

but feel free to help them out yourself

[earnest tangle]

honestly your messages read like "go ask someone else"

[odd ember]

I've given the advice I could give

I don't know what else you can expect

if you have more advice than that to give, feel free

otherwise you're just here criticizing me for being constructive

[wild crater]

I figured the blueprint debugger "watches" would display the watched values at runtime but they don't. It only works during breaks?

[odd ember]

yeah sadly

there's also a window where they'll show up that I can't remember the name of, but it's accessible from the window menu

maybe blueprint debugger?

[wild crater]

yes that's what I was trying out

I figured it would display watches at runtime

as it doesn't do that, I suppose the only advantage is that you can watch values from different blueprints in one window. Which is still pretty neat I guess

[odd ember]

yeah it's not great. I think printing values is still the best way to iterate over numbers. watches can sometimes help expose variables outside of scope

[wild crater]

yes

thx

[slow pewter]

Which is the Best Way to Have different Widgets Stored?; an User Widget Class, Array ?

[odd ember]

stored how? what are you intending to do?

[slow pewter]

Dynamically Created Widgets like an Dialogue Creator, and there are stored different Widgets in a Row, if all would be the same its easy i would take an Normal Object Widget Array, but because they are different Widgets gets more Complicated i guess

and than Im saving all of them, like all Widgets get Stored in Savegame// and loaded correctly

[unreal token]

is there a such thing as one box trigger to open up all the sliding doors, individually? or do i have to make 12 box triggers and 24 on-overlap bp?

[quick imp]

Hey im just trying to make sure this is the best way to setup key remapping for users within their settings?

[gentle urchin]

Cant you do a common dialog widget and just feed data to it?

[odd ember]

sounds like you don't necessarily need individual widgets, just individual widget parameters? like text, size, options?

[slow pewter]

Yeah but its more i want to learn how to do stuff like this, like Different Widgets in an Array, and let them Loaded Correctly

[slow pewter]

in theory yes, and Image Size, but thats lot because on Some i have Size boxes and desired Sizes and on Some Fill Panel

[odd ember]

but holding widgets in an array isn't really a thing that's good to do? it's not an architectural pattern eitehr

you want to separate data from containers

[slow pewter]

Im Storing Structures, but i want that Widgets Array for an reference so i can create with For each LOOP; that Matching Object Widget

[odd ember]

so I'd have perhaps an array (or a data table) of WidgetParameters that then contain whatever you need. then you can expose parameters on the create widget node

and feed them directly

that's the "elegant" way of doing things

[slow pewter]

im Also Saving only the Struct, that Array would just be for, an Reference at Which Array Index gets which Widget

[odd ember]

then you can just have the struct array determine the order

[slow pewter]

my Plan was an user Widget Class, and trying to Add, Widgets Object CLasses into it, thats working, but If i try to Branch it, and like is this That Widget, it always fail

[odd ember]

yeah but why make it determined by the widget?

it's the struct data that matters

not the widget itself

now for all of this, if you're making something like a dialogue sequence (or tree or graph or whatever)

you might need a more flexible structure than just the array

[slow pewter]

Yeah i get your Point

probably if i only Create an Enum and an Array of it, should work too

[odd ember]

why the Enum?

[slow pewter]

with my Features Tool im just used the Object Index an Custom Integer that worked very well

[odd ember]

right but you're entering territory where structure is really important

[slow pewter]

Yes feeding data is not the Problem, but Like Normal Dialogue// 2 Choices, should be different Arrays, and it Should be on the Same order

[odd ember]

and where architecture can have a big influence on how everything works

[slow pewter]

I have an Structure and my Plan was , saving the Reference in that Structure, as an Widget, and because there are different Widgets i needed to Use, User Widget Class, otherwise i only could add one Object Widget Reference

[odd ember]

what I mean it's not a struct as the type of data

[slow pewter]

Yeah thats true, thats why im asking, and thinking, of Something like this

[odd ember]

but structure as in system architecture

i.e. a tree or a graph

or however you want your dialogue system to work out

a struct is a data container

[slow pewter]

Basically Tree

[odd ember]

right

so for a tree you need nodes

a node is a class

in this case, each node will contain data (which you probably already have in your struct)

and will point to towards other nodes that are below it in the tree (the child nodes)

[slow pewter]

Yes

[odd ember]

so a node can be subclassed as well

so you can have a node with 1 option, with multiple options etc.

depending on how flexible your system needs to be

then in your data you just need to specify how many options you expect

and the node handles the logic for it

[gentle urchin]

Choises are fed in aswell, widget dynamically creates the widget according to incoming data

[odd ember]

keep in mind the tree only has the data at this point still

at any point you just query the tree to get the next node to create the widget with the data parameters

[slow pewter]

Yeah but, so i shouldnt Use, Classes like that?, was just thinking of that, in theory it would be useable for me like i wanted it

[odd ember]

you are using classes, but an array is too simple of a way to hold data here

the way you contain the structure is that each node knows all of its child nodes

and only that

[slow pewter]

yeah i understand that

[slow pewter]

Im still beginner at this Code more Artist side, but it sounds like the Best Way to do it, im try it, but sitll have an Structure and it Worked for Tools like Features/ Character Entries really good and dont want to Delete all i will look into it

Thanks Bro

[odd ember]

the alternative if you don't want to do it this way is that you will be doing manual work and manually linking up everything

if you rather do that for every dialogue option feel free

but you're going to run into difficulties if you don't set it up correctly

[gentle urchin]

How would you avoid having to link up a branching dialog ?

[fair sun]

is there a implements interface node for class? This does not work 😦

[gentle urchin]

At some point it must be defined , even if it means linking two nodes

[odd ember]

you can't avoid linking it up, but you can avoid manual links for every single option for instance

[sharp rapids]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/DoesImplementInterface/

[odd ember]

you can also avoid actually structuring it in order

[fair sun]

this is for an already spawned object, I want to check the class reference

[slow pewter]

good point

[gentle urchin]

Hmm, not sure how that'd be done really.

Havnt spent a tremendous amount of time on it tho

[odd ember]

the tree would handle it as part of the structure. the tree breaks down e.g. every data table entry and creates nodes accordingly

every entry only references the child entries

[gentle urchin]

Oh lol

I totally missed the tree part.

Makes sense then !

[odd ember]

graphs and trees are really cruicial for making systems like these that have discrete data

https://www.geeksforgeeks.org/introduction-to-tree-data-structure/

[sharp rapids]

Ah, sorry idk then

[agile hound]

I’m wondering if i’m asking this question in the right place, not too use to Discord :S anyone can help me figure out how to draw a line (not just a debug line) from my character to the enemy in my turned based RPG… similar to ffxii lines as shown on the picture. I’m pretty sure that i would need to make my own material for the line itself which is fine… my question is how do i create that line (probably spline?) lol

[odd ember]

https://en.wikipedia.org/wiki/Trie here's the type of tree that's really fitting for this purpose, stolen from stuff that makes your autocompletion stuff happening

[odd ember]

you'd need a mesh, a material, a spline and code

you can potentially do it without the spline

[gentle urchin]

I think so too

[odd ember]

but I think having spline tangents that you move around will be easier

[gentle urchin]

Mat offset

[slow pewter]

Yeah bro thanks nice stuff, but to get this good working in only BP, is i guess really hard

[gentle urchin]

Would solve the curve

[odd ember]

not at all. create an object subclass called Node. inside Node create an array of Node Objects called ChildNodes. create an entry for your data that you want the node to have

[agile hound]

The characters won’t be moving when the spline is drawn on screen… turned based RPG. I want the spline to appear as a target select kind of thing.
The mesh… would be a very thin cylinder??? Lol

[odd ember]

create another object class called Tree that then takes a list of Nodes as a parameter and organizes them when constructed

[gentle urchin]

Yepp

[agile hound]

What did you mean by mat offset?

[odd ember]

then you have your structs or data table entries that you use to spawn nodes that then are directly fed into the tree that then arranges them

[slow pewter]

That sounds very well and smart, but at my Guess like im still want to Edit it etc, and like assign Character Entries, and if i have One Array thats Stored and Work, like Index based, or Reference based , i do it more easier for that or? , as i said still beginner

Well now a lot time to think, Project is Compiling at Ue5 PW 😄

gg

[odd ember]

well you can't use "index" on a tree in the same way you do on an array, because you are not dealing with a linear structure. but equally once you've set up your tree you no longer have to concern yourself with the index, because the node you are on already has the only options available for the next node(s)

so as long as you have 1 node, you know what the options from that node are

they are contained within the node itself

[slow pewter]

Yeah but how exactly i would store the Data in it with SG? when i dont have an Index ? , and especially if I edit , remove entries, Nodes, i need the Index for Each Node, to communicate good with the Savegame

probably i think too complicated with that

[odd ember]

so instead of saying ArrayIndex++ you just do Tree.GetNextNode()

[gentle urchin]

Material vertex displacement

World position offset

[odd ember]

I don't know how this relates to a save game. what are you trying to do?

you want to save what dialogue option you are at?

[slow pewter]

Yeah like i said i want to create it dynamically not Only for an End User, its more i want to edit it, I create an Concept Programm, to interact Deeply with my Project,

thats why i need SG, to get all Stored correctly

[odd ember]

I'm not sure what this means

[slow pewter]

I create it at Runtime/edit an Runtime, not on Editor

[odd ember]

but you can save the tree object instance and the node you're currently on

[slow pewter]

Yeah i try to understand how exactly to ge tthis to work as u said, but , Its more Complicated like i need to create all Dynamically at Runtime, so i need to Edit all at runtime noo, not on Unreal Editor, and to edit and save them, for me its more difficult with that Method like u said,, for an Editor Setup i guess that Would work very well

[odd ember]

it's only as complicated as what you want to make. it's true that it's harder to do than other things, especially in BP. but if you're in the business of making systems these are fundamental structures you'll have to learn to support your gameplay or design intention

[odd ember]

like I said you can save them quite easily as object instances. it shouldn't be any different than saving an array. the tree is the array, the current node is the index

[slow pewter]

Yeah i understand that thanks Bro, I will try to get something like this to Work,

[gentle urchin]

[viscid python]

What do I have to add/change here to make the widget (equipment window) appear with all functionality in the world instead of the screen?

[odd ember]

you need a widget component

[viscid python]

I added a widget component to my actor but then the widget will not update, it's shown in the world but without any highlighting etc. when I hover over elements etc. Is there a way to set this up via blueprint? The widget works on the screen as it should 🤔

[trim matrix]

Is there any way to open .uasset/.uexp blueprint files from a game I've unpacked into a sample project?

I don't care if the dependencies are wrong / doesn't work - I'd just like to see the event graph and all that, even with multiple errors

I tried the copy-paste .uasset trick but UE doesn't see them, and I'm on the right engine version

[icy dragon]

You can't.

[trim matrix]

ok weeb, anyone else?

[icy dragon]

Go ahead. I'm sure you'll get the same answer as I said.

Packed assets from UE4 games are already cooked, in a sense that they can't be opened in editor anymore. Especially with Blueprints.

If it's your own project, it's a wake up call to make backups of your source files.

How do I access the speed variable of a third person character? I am trying to access the variable in my code, but it isnt working

[dapper forum]

The difference between this one and the one that's working is the timeline for the animation, could it be the cause?

[patent plover]

I am following a tutorial so that could be a reason

[odd ember]

you're in the animBP, not in your third person character BP

[patent plover]

yeah, so how do I access that?

[odd ember]

what do you want to access?

and where do you want to access it?

[patent plover]

I mean, I am using the template of 3rd person character, and I want to access its speed

[odd ember]

generally the animBP should reference the character, but the character should not reference the animBP

[odd ember]

if you look in the BP section of the animBP, you can actually see that speed is just the character movement component's velocity vector's length

[gentle urchin]

Not seeing any timeline, but perhaps?

Are you calling this from a timeline among other things?

[hollow gorge]

Open your ThirdPersonCharacter BP (If you have choosen 3rd person template) then go click "character movememt component" then you can find the variables in your details panel. You can change them within the ThirdPersonCharacter or outside, if that other object has a reference to your ThirdPersonCharacter (I believe).

[dapper forum]

Yeah, it's right before the function, you can see it's feeding the lerp alpha

[gentle urchin]

The loop iterator is by default something like 1mill

Yeah i figured it was something like that :p

What else is called on this timeline?

[dapper forum]

right now just this function

[patent plover]

oh ok thanks, I tried it before, didn't work, but this time it worked, idk how

[gentle urchin]

So unplugging it removes the loop issue?

[rare gale]

This is the event graph of your AnimBP

[patent plover]

oh ok

[dapper forum]

yeah, just tested it, the loop finishes but it breaks the animation

so I guess my question is, how do I use timelines with for each loops lol

[odd ember]

why do you want to use timelines with for each loops

that seems like a recipe for disaster

[dapper forum]

because I need to animate the positioning of my object

[odd ember]

okay but where does the foreachloop enter into that equation?

[gentle urchin]

Many objects

🤔

[rare gale]

Here's how I have mine set up. I run the function on the widget I cast to on BeginPlay then I can manipulate it on the Treasure Chest BP with that reference (PickupLabel_Ref)

[dapper forum]

it grabs all locations from my invisble grid and set all the objects to move to those locations

[odd ember]

why isn't each object responsible for its own movement?

[gentle urchin]

Premature optimizaton? 😆

Jk

[dapper forum]

because there are 36 of them, and their future location is randomized each gameplay

[odd ember]

nah in most cases people don't understand object responsibility. there are very few resources on that specifically when talking BP

[odd ember]

that's fine? they can still be responsible for their own movement?

[gentle urchin]

Random on seed -> win?

[odd ember]

all it takes to solve your problem is to move the timeline logic into each object instead of having it done in another object

[mossy valley]

Hey so I can't Character Movement Component -> Get Velocity on the client of my game. It really seems like my event tick never runs through the client version of my update slide function, despite the client being able to slide exactly like how the server does. Anybody have any ideas why? (This is in event tick)

[gentle urchin]

It is weird that 36 objects causes infinite loop detection tho..

[dapper forum]

I guess that makes sense

[odd ember]

a general rule of thumb is that each object is responsible for its own actions

[dapper forum]

I think it's because the timeline exec's an update istead of a regular exec

[gentle urchin]

Can you show the timeline?

For kicks

[dapper forum]

you're right, I'll do it like you said, thanks!

[odd ember]

timelines update at tick speed, so it may be it cannot tick through all of them

[dapper forum]

there's actually nothing much to see

[gentle urchin]

Odd for sure

[odd ember]

ah yes, New Function 0, the good old classic

[dapper forum]

lol i'd rename it eventually

thanks guys! have a nice day you all

[mossy valley]

Hey so I can't
Character Movement Component -> Get Velocity

[viscid python]

Thank you very much 🙂

[odd ember]

I'd ask in #multiplayer

[mossy valley]

Okay my b

[gritty trout]

I'm following this video https://youtu.be/gH88ZKB1_IE?t=2635 about Blueprint Task Trees and at 43:55 he pulls up the AI Controller with some variables in it. I do not know how to get the Blackboard variables to be referenced in my AIC like in the video

[charred berry]

following https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/Sequencer/HowTo/TriggeringSequences/ , and trying to get add on actor begin overlap, which I found 'assign on' at least ( not add on), but the 'triggerbox' isn't shown in that bp function, is this a change or is something wrong with my cinematic scene or ? TY !~!

[hollow gorge]

Maybe you'll find the answer in the youtube comments.
Edit: ctrl + f and type in 43 that way you might find it quick.

[gritty trout]

I searched manually and then ctrl+f for 43 and I still haven't found anything relevant

[charred flint]

I tried changing it like this but that doesnt respond at all it seems.

Anyone that can help me out by any chance?^^ I am totally stuck on this

[hexed glade]

Is it possible to access variables from a characters' own animation blueprint without casting?

[dawn gazelle]

This tutorial assumes you're working in the level blueprint. After you've placed a trigger box in the level, you can add the relevant event like so:

[gentle urchin]

Not sure what im seeing

Hardcoded values is not great for this 😃

[charred berry]

weird, I was typing add on actor and it wasn't findingit, TY Datura I guess they should update the doc ;))

[hollow gorge]

Are you trying to make this log shortcut work like the one in Ardougne?
You could do something like: Player clicks on log, character walks up to it (player input is disables for the duration OR player input cancels action). You'd probably take the current player's location and destination location in a looped lerp node to make the character walk to your destination. By using a boolean or any other variable really, you could determine which side the player starts and which side the player ends on.

[keen widget]

How to change blueprint mouse navigation buttons?
how to **pan **with middle click
and disconnect nodes connections with right click

[gentle urchin]

You should prob do comparator for current char location^^

Get player char-> get actor location -> getUnitDirection

[tulip iris]

Trying to connect a wobbly physics flag (skeletal mesh) to my vehicles skeletal mesh flag socket. Attaching it doesn't work and the flag just flops to the ground. Any advice?

[gentle urchin]

Personally id have this logic in the actor itself aswell, so that its easily reusable

[charred berry]

OK I got it, by just right clicking on triggerbox in outliner then chose addon begin overlap and now its showing triggerbox,,all good , I'd forgotten one can do that, whew!!

[gritty trout]

I am still having this problem, I do not know what terms and context to search to find the solution

[junior badge]

Hey guys, I want to create a blueprint that does the following.

I have a master level with different sub-levels and 2 different character controllers, so what I want to do is

When the main level is loaded, check if I am on the main level, If I am not on the main level character controller 2 posses the pawn.
Already got the posses part working, but don't know how to validate which level I am

Can anyone help me please?

[swift kestrel]

Go into your ai controller and get the blackboard and then drag off that and search for "Set value as".

[wraith eagle]

Hi there!
Im trying to get AI healthbars to only appear when I mouseover them in a topdown game, but I must be doing something wrong?

[gritty trout]

@swift kestrel @rare gale
My problem is that I do not have the blackboard variables in my AI Controller like in the tutorial video.

In the tutorial video when he edits the AIC you can see there are variables that are References to the Blackboard values and in my AIC, set up the same way, I do not have these reference values.

I just noticed the "Make literal name" node

[high sapphire]

Oh, is it because I'm using the tags to try and find the row? Should I name the rows after the tags?

[dawn gazelle]

Yes

[gentle urchin]

Correct indeeed 😃

[dawn gazelle]

Those events are returning a reference to the component that was overlapped which wouldn't be a reference to your character. If this is within your character, then there is no need to cast anything.

[true valve]

Anyway to paginate this getting data from datatable? https://gyazo.com/91c2f8f98a1b38e35b1673c5a5754123

[swift kestrel]

You should probably watch a video on the basics of UE AI. Ryan laley and LeafBranchGames have good tutorials for that.

[wraith eagle]

@dawn gazelle this is within the NPC event graph

AI*

[novel rock]

how do i look up the class?

[gritty trout]

Thank you, I will check those out as well 🙂

[swift kestrel]

Theres also the updated AI tutorial by Epic. https://www.youtube.com/watch?v=iY1jnFvHgbE

[dawn gazelle]

Is it an AI Controller class, or is it a character class?

[high sapphire]

Hm, so now the name and description are properly updating, but not the icon or the count
And it's also only showing the health potion even after I picked up 3 magic potions too

[wraith eagle]

character

[dawn gazelle]

Then it shouldn't require any casting.

[gentle urchin]

So chech that you feed it a valid icon, @high sapphire

Also verify your addition logic for the inventory

[dawn gazelle]

Nice to see some progress on that inventory 😄

[gentle urchin]

Structs in a loop must be returned by ref to set member directly

[high sapphire]

Yeah, I took a few days to work on the options menu instead since that was giving me less of a headache, heh

[gentle urchin]

Regular loops return a copy

[high sapphire]

How do I do that?

[gentle urchin]

When you update thr icon

Simply print the icon refs display name

[high sapphire]

Is it because this is a soft reference?

[wraith eagle]

@dawn gazelle It works is I use On component begin overlap, then it shows up when I walk inside the sphere, but On begin cursor over does not work

[gentle urchin]

Likely, yes

[wraith eagle]

when I use*

[gentle urchin]

Have you enabled cursor over events?

[wraith eagle]

hmm where do I need to enable that?

[gentle urchin]

In the player controller

[high sapphire]

Yeah, it was because it was a soft reference, so at least that was an easy solution

[icy dragon]

Of course it will fall through, you're enabling physics simulation as a component. That is more used for static meshes.

[wraith eagle]

@dawn gazelle in the event graph or somewhere else?

[high sapphire]

And the amount not updating is probably because I'm not updating the datatable's amount, isn't it

[gentle urchin]

In the playercontroller settings , details panel

[gentle urchin]

Datatable cant be edited, so i hope the amount is not in there 😄

[icy dragon]

For wobbly antennae, best to simulate the springy physics in anim BP with anim dynamics (or chained tailing logic in Control Rig)

[high sapphire]

Ah
So I have to store the amount elsewhere, then

[gentle urchin]

In the inventory preferably

So the inventory struct would be a gameplaytag + amount

[wraith eagle]

Like this now @gentle urchin

[high sapphire]

Yeah, since I was told to set up the inventories as components attached to the player, the component's contents are an array of tags & amounts. Just a thing of figuring out how to pass the data off to the UI.
This is the widget that gets spawned in the list, MenuItemObject is a widget object that just passes info

[gentle urchin]

Yupp 😆

[wraith eagle]

well, still nothing happens tho

[gentle urchin]

Object response on visibility channel?

[gentle urchin]

Right, where it is stored matters very little 😄

[tulip iris]

There are a number of ways it can be done but surely connecting a skeletal mesh to another is possible correct?

[gentle urchin]

The widget has a inventory ref, correct?

[high sapphire]

Yeah

[icy dragon]

Just the attachment alone is not a problem

[white field]

https://blueprintue.com/blueprint/rc7t2awj/

sometimes it is useful to turn contextual node suggestions on or off

[tulip iris]

So you don't know how to attach to skeletal meshes simulating physics? (I don't either)

[gentle urchin]

So the amount is avaliable, yes?

[high sapphire]

Okay so the count is updating properly.. kind of
But it's not spawning a new widget for different items (I picked up 3 health potions and 3 magic potions)

[gentle urchin]

They are probably marked by the same tag?

What does your pickup object data look like?

[high sapphire]

As in the object itself that's being picked up, or?

[gentle urchin]

Ye

[icy dragon]

The skelmesh itself can do its own anim dynamics, not sure what's the hold up, especially with a simple attach job

[high sapphire]

I can probably remove the amount thing from that struct, actually

[gentle urchin]

Yepp

All but tag + amount

So basically just FInventoryStruct ^^

[high sapphire]

Oh, were you meaning the widget that passes info from one widget to the next?

Or do I only need to store the icon/etc. in the datatable and not the objects themselves?

[icy dragon]

I've been doing similar thing numerous times, because of anime models, so skeletal meshes can have its own anim dynamics while attached to another skelmesh or copy pose from parent skelmesh.

Only set master pose component that disable it.

[gentle urchin]

Exactly. Only in the DB

[high sapphire]

Ah

[novel rock]

it doesn't want to connect

[tulip iris]

I'll have to look more into it

[gentle urchin]

I generally dont like the listview widget, but how do you populate the listview itself?

Im biased, ignore the first part 🤣

[high sapphire]

Yeah, since I'm still having it show 6 health potions in the UI despite having 3 health potions and 3 magic potions.. I'm assuming my mistake is something to do with this foreach loop

[gentle urchin]

Probably not

There probably IS 6 healthpotions in your inventory

Due to tag check fail

[high sapphire]

This is how the inventory component adds the items (trying to remember who helped me with this part, since I've had a handful of people on this server helping me by now)

[gentle urchin]

Theres a chevk for the tags

TagMatchesExact

Also, dont drag from the inputs 😄

Once compiled, you can get the inputs as variables inside the function

Looks waaay cleaner

Also

You dont have to break

After the branch, you can instantly add, and return directly in the loop body !

[high sapphire]

It looks like the tags are right, at least in the adding side

[gentle urchin]

Yeah but the match when they shouldnt i bet

Use DoesTagMatchExact

[gentle urchin]

TagMatch?

Cant recall if its just a bool on the match node

[gentle urchin]

Yes!

[high sapphire]

Yeah, it was a bool on Matches Tag

[gentle urchin]

Good

Use that for the branch

[high sapphire]

Still getting x6 health potions in the UI though

.. Oh right

-_- Might help if I connect the bool output

Or not, still showing x6

[dawn gazelle]

Same difference.

[gentle urchin]

The more one knows ^^

[high sapphire]

But yeah, it's still showing health potion x6

Knowing me, it's probably a mistake somewhere in a foreach loop

Or could this be the culprit? Should I be setting the variable to false off of that false branch?

Hm.. Well, that's closer.

Not sure why the health potions are showing up properly as x3 but the magic potions are showing up as three instances of x1

[gentle urchin]

Instead of break

Move whats on the 'completed' foind branch and move it to the loop body branch

Is this a local var btw?

[high sapphire]

No, it's not a local var

So move all of this into the loop body?

Where, exactly?

[gentle urchin]

Dont break on both true and false

Move it to after true

On the loop body branch

[high sapphire]

Looks like just changing that fixed it

[gentle urchin]

Show the final code

😅

[gentle urchin]

I guess that'll do

[high sapphire]

Thank you for your help! Feels good to have that finally working

[gentle urchin]

No worries! Keep making progress :)

[high sapphire]

Now I can go back to figuring out how to smack the saving/loading system into behaving, once I have some lunch

[twilit gull]

i've disabled print string output somehow how can this be fixed?

[gentle urchin]

Yepp ! Id still do a tiny cleanup of the function but it matters very little

[twilit gull]

not the checkbox in the printstring, they just appear in the logs

[odd ember]

it's usually on the node

[twilit gull]

the node is fine, but i see output only in console

[high sapphire]

Yeah, I can focus on cleanup once I get the functions well, functional. Studio (the class I'm making this for, which is basically my senior project) is all about minimum viable product now and polish/fine tune once you have the minimum viable product

[gentle urchin]

Ah

Sensible

Even at mvp i try to keep my code relatively clean/clear purposed, so that when bugs appear its easier to get back into it

Without the 50 crossing wires etc :p

[high sapphire]

Yeah, that's fair
And I imagine cleaner Blueprints also mean better performance, even if only slightly

[gentle urchin]

Your first bug will be picking up another item when you're at max stack amount :p

'Bug'. No overflow or amount check

[odd ember]

well it's print to screen that matters in this case. which probably means it's a console setting somewhere. I'd ask in #ue4-general or somewhere where console commands are known. maybe #cpp

[gentle urchin]

Disable all strings...

What was the command...

"disableallscreenmessages" in console

[hybrid hare]

Hi, I did a setup aiming at opening a drawer (I'll add VR actions later on, now it's only using a trigger box but it won't change a thing to my problem) but when opening it the draer, it just opens too fast. i played with the curve settings but it doesn't change a thing (curve has an impat though on roatating doors using a rotator,). Any idea ? I'd to open the drawer progressively not instantly

[vital aspen]

On Drag Detected, what sets the item getting dragged

[gentle urchin]

You caan use payload

Plug self into payload,

[vital aspen]

I never used it or needed it

[gentle urchin]

Then on drop get payload, cast to your widget type, and access all of its data

Makes the need for custom drag operations abundant

Unless you need something truly custom

[vital aspen]

No, just plain as I can get

Ok, so how what do I do

[gentle urchin]

Try payload then ^^

[vital aspen]

I never used it before.

[gentle urchin]

You dont need the first cast i think

Payload is just a container for the reference you pass to it

[vital aspen]

? that's the drag and drop cast

[gentle urchin]

Ye

You dont really need it

You can get payload directly

And cast to your widget class

[vital aspen]

I tried that nothing

[gentle urchin]

Check the drop input

The object you plug into your itemdeaganddrop cast

[gentle urchin]

Operation -> Payload -> Cast to your widget

[vital aspen]

Like this

[gentle urchin]

Is the widget you're dragging "UI_Dropbox"?

[vital aspen]

No.

[gentle urchin]

Cast to the widget you're dragging

[vital aspen]

That's on drop

[gentle urchin]

Ye

[vital aspen]

sorry, I new at this, I don't under stand

you mean cast to the widget I'm dragging from

[gentle urchin]

Ye

Thats the payload

[vital aspen]

ok, now what

[rain egret]

this might be a stupid question but how can i push another pawn? they both have floating pawn movement

[gentle urchin]

Now you can access all of its data @vital aspen

All the data that exist in the instance you were dragging !

[vital aspen]

Sorry, The last part I have no idea what you mean. The index isn't there. The itemName isn't there. I'm confused

[gentle urchin]

Probably wrong cast?

Are you not dragging UI_InventorySlot or smth?

[vital aspen]

I'm draging from the players inventory (UI_inventory) to the UI_Dropbox

[gentle urchin]

But ur dragging a slot, right?

Not the entire inventory?

[vital aspen]

This is an Object inventory So it's from an index.

or an array is what I should have said

[gentle urchin]

The drag is initiated from a widget

This widget must habe some representation

[vital aspen]

Yes, from my UI_Inventory

[gentle urchin]

So there is no slots in the inventory?

[vital aspen]

That's where I'm draging from

This is my inventory

[gentle urchin]

UI_InventorySlot is what you wanna cast to

Thats what you're dragging

Not the inventory.

[wanton knoll]

does anyone have any sort of tutorial on how to make an end game screen after collecting all of the coins with the time showing

[vital aspen]

That's why

[gentle urchin]

Yepp

[vital aspen]

last question, what sets the ItemName value in the On drag detected.

That keeps returning none

It should return the Name of the item it's dragging

[gentle urchin]

If you've ever updated it, sure

I would think its not updated/set

[vital aspen]

Yes, I know, That's what I can't figure out

[gentle urchin]

Check where you set it, use print string to verify

[vital aspen]

ok, thats where we are both confused it. Where do I set the ItemName at ????

[gentle urchin]

Idunno, up to your logic? 😂

How do you update/populate the slots?

[vital aspen]

when I drag it from the players slots. It should know what item name it's dragging from what I been told

See I'm not worried about updating the slots. My issue is when I drag from the players slot. There should be something that it reads to return what is getting dragged

[gentle urchin]

Payload is that something

Payload as it is now has a reference to the slot you've dragged

[dawn gazelle]

You need to imagine that each slot already would contain its own data based on however you set that data in the slot originally.
The below image appears to be the creation of your drag and drop operation. The Drag and Drop operation will contain whatever data you populate into it. The OnDrop on the receiving end will have an "Operation" pin that you can cast to your ItemDragAndDrop class and then pull the data out of the operation.

[vital aspen]

from what you told me, Yes that's what it does

Ok, this is what it should look like.

When I drag from the playersslots. The ItemName value should have somehing added to it. It doesn't, Other then the work None

[gentle urchin]

You dont need the index, nor the name as inputs

as long as using payload is fine, ofcourse

[vital aspen]

for some reason it looks like on On Drop doesn't run when I drop it

[dusk nymph]

how can i have rotation for my boxoverlapactors node

[odd ember]

what do you mean?

[dusk nymph]

i mean rotation for the box

[teal talon]

Inside my Landscape Materials I have this options for Rain Drops to show on puddles, How would I enable/disable this from a blueprint? So I can enable it when I fire the rain effect from my goodskys blueprint.

[odd ember]

rotate the actor that spawns the box overlap and see if that works? otherwise you could use a collision instead

[dusk nymph]

even if I did there is no place to enter the rotation

[main pollen]

guys I need help

follow camera is from a different blueprint and I don't know what is up with that target thing

I don't even know what to connect it

[haughty temple]

if its from different bp would need to cast to the bp that it is part of to pull the variable out

[dusk nymph]

@haughty temple do you have a solution please

[odd ember]

did what?

[dusk nymph]

rotate the actor that spawns the box
