blueprint

[gray lantern]

it's like a key right?

[lunar sleet]

It’s like an excel table

And yeah pretty sure it iterates over all of it or at least until it finds it. You can look at the source code to see exactly how they do it

[somber elbow]

@lunar sleet

[drowsy steppe]

Hey guys. Any idea why RVO avoidance is not working with my npcs?

[silent plaza]

Hey friends 🙂 I use the Third person Template with Enhanced Input. When I log the Enhanced Input Action IA_Move "Action Value X" I only have either 1 or -1 when I pressed Left or Right, but it never goes back to 0, and it doesn't increase progressively. Do you know why? Thanks 🙂

[frosty heron]

You are using keyboard, A or D will be 1 or -1. If you set your key as such. There shouldn't in between.

I think

[trim matrix]

what about a controller?

which isn't 1 or 0 or -1

[frosty heron]

Don't know, don't intend to plugin my analog stick to find out.

[worthy jasper]

Generally this is just the difference between controller and mouse and keyboard inputs

[frosty heron]

There's probably in between for analogs

[worthy jasper]

Controllers let you get smaller values

Mouse and keyboard is typical pressed or not

hence why movement looks different in games that support inputs

[frosty heron]

Yup

[worthy jasper]

And you can usually tell what input a player is using by watching how their character moves

Unless there is a specific problem I wouldn’t worry about it. It’s the difference of input. Keyboard and mouse are typically much snappier

[lunar sleet]

I’d have to see how your spawn time function works, can you show a screenshot?

[trim matrix]

why would you do once on begin overlap^???

[worthy jasper]

To do code once in an overlap?

[trim matrix]

it seems so wrong

[worthy jasper]

Well as with anything it depends on what your trying to do

But yeah on face value it’s probably not what you want

[trim matrix]

create a bool called, has been hit, set it to true when it's hit and you control it on your own

[worthy jasper]

That is another way to do it yeah

[frosty heron]

Depending on the context, I rather use do once node over branch

[lunar sleet]

@somber elbow also you can try using a Sequence node. On first pin, Do Once with everything up to the SpawnTile. On 2nd pin the rest of the nodes. Will need some testing but give it a shot

[frosty heron]

Don't feel like making extra variable when I don't need to.

[worthy jasper]

Kinda my thought too

And a do once has a reset

[trim matrix]

ooooof, setting the variable to false

[worthy jasper]

Speaking generally, Do once is used when you want the code to execute at least once

a branch is good if you potentially don’t want the code to execute at all

Or want to change how it’s executed

[worthy jasper]

What?

[trim matrix]

resetting in this case is the same as setting it to the opposite value

[worthy jasper]

Except with a lot less nodes

In your scenario you have to remember to set the variable before and probably after the branch

[trim matrix]

ofc

[worthy jasper]

For a do once it’s a single node that fires the code at least once

With the ability to reset it if you want it to happen again

[trim matrix]

sure

but that doesn't excist in C++..

[worthy jasper]

well I’m not speaking how to do it in c++ XD

You were asking about the blueprint node do once

[frosty heron]

Which is just a macro

[worthy jasper]

Mhm

[frosty heron]

Surely doable in cpp too but I don't know better

Datura would know

[faint creek]

Somebody could help me?

[frosty heron]

#gameplay-ai might know

[dawn gazelle]

Sure it does. It's effectively the same thing as creating a bool and setting it the first time through the do once and calling another function, and then setting it false if you want to reset it.

[faint creek]

Ah ok thanks

[trim matrix]

ew

I hate maccros

[lofty rapids]

i have not got into macros at all yet but they look interesting

[silent plaza]

Hey thank you 🙂 it doesn't go back to 0 when nothing is pressed ?

[dawn gazelle]

Yea it's ugly, but it works XD
You could absolutely set up something similar in C++ by passing around a couple of bools that you have on your class and pass in a function through to your DoOnce function, but then you'll end up with a ton of bools to manage something like this in C++.

[frosty heron]

How are you printing it?

[lofty rapids]

well your using enhanced input right ? if your going off triggered think about it, iit won't be zero

started, triggered

these happen when your using the buttons so they will have a value

you can use the old axis mapping and get when it's zero i thinkor maybe there is another execution comming out of the enhanced input ? i still use the old stuff

[silk bay]

Hello, I'm trying to remove the widget during some dialog. It prints the string but doesn't remove the UI. Any ideas?

[frosty heron]

From WBUI straight to the target

[lunar sleet]

No need for the cast node if you’re using spawn node in that tile function. Also try the sequence node I mentioned

[trim matrix]

Why would you ever remove it if you never added it to the viewport?

[silk bay]

that didn't work :/ I'm trying to remove one UI before loading another

[dim siren]

Not even on Completed? You could promote the axises to variables and set them to 0 on completed also.

[frosty heron]

You are trying to remove the UI that you just creates, which you never add to viewport either.

[lofty rapids]

why is that called master ?

[spring osprey]

Hi guys, I want to make a simple save inventory system for my character so when I load a new map the data from the previous one keeps in the new, could someone help me?

[silk bay]

ah ok, I see. I'm trying to remove a widget that's in a component that's always visible, but want it gone during a cinematic

[lofty rapids]

do you want it to "save" as in like a file so you can shut it off, turn it back on and load ?

[frosty heron]

Make it so then. You will need to keep a ref to every widget you create, and bring them forth when you want to do something with it.

[lofty rapids]

or just persist through levels ?

[spring osprey]

I would like it to delete when the game closes like a temporal save data

[lofty rapids]

save it in the game instance

use a bunch of variables

or structs ig, but you could just use variables in the instance

these will persist across level loads

pretty much the only thing that does that

[somber elbow]

Idk, it sounds cool

[lofty rapids]

whats the problem ?

the note probably says it's already that class ?

[spring osprey]

and how can I do that? im kinda new with ue5

[lofty rapids]

right click in content drawer, blueprint class, search for game instance

create that

then in your project settings, search for "instance"

and set the game instance class to the one you made

then yyou can get the game instance from just about anywhere

and now you have a ref that is persistent across levels

add some stuff and your all set you have a save/load untill the game shuts off

[somber elbow]

@lunar sleet It looks this way now. But now It stops counting after 1 and stops spawning tiles

And i have this error

[lofty rapids]

you don't want to cross exec lines like that

make a reference

and whats the do once all about ? you only want it to score points once ?

[lunar sleet]

Promote the cast return to a variable

[lofty rapids]

i would probably cast to game mode on begin play

unless it's going to change at some point

[lofty rapids]

for one thing you never reset the do once but idk exactly what your trying to do

what does spawn tile do ? spawn the next map ?

[somber elbow]

Here is the story of the issue

this

[silk bay]

thanks so much! This put me on the right track and figured it out.

[dark drum]

Remove the sequence and connect what called on the second pin at the end of the chain on the first pin.

[lofty rapids]

a couple things but first i would say make it work one way going up, and if you destroy it you should be good because you won't overlap it again, but if your using it in some other logic like tick or something then you may get accessed none after destroying it

[spring osprey]

so like this? (this is for the battery of a flashlight)

[somber elbow]

Im not quite sure which one i should promote to variable

[somber elbow]

Thats how it was in the beginning

[lofty rapids]

well you cast to the instance, set it to a variable, but your not setting any variable on the game instance, just returning something else

[dark drum]

What was the issue with it being that way?

[spring osprey]

so what should I do?

[lofty rapids]

this function is supposed to get the percent but you want it to persist across levels or when you load the level again still have the same values ?

[somber elbow]

#blueprint message

[spring osprey]

I want to make the game remember for example the battery the player had in the previous lvl

[lofty rapids]

you can think of in this case the game instance as your "storage" for stuff that persists, so you need variables and maybe even functions,events on there that you use in the gaame

if you just cast to the instance and don't use it then it's fairly useless

so when you cast to it, you pull off and get/set the values you want to store

in the case of a percent, instead of using the playerref like you did use the game instance and some variables on that

[lofty rapids]

so then what is the battery ? depending on what it is probably an actor with some settings ? are they default settings do you change them dynamically ?

different things would need to be "saved" in different ways

[lofty rapids]

your probably getting accessed none because your pulling from a different execution path

[spring osprey]

this is what I use for the battery, its just a light in the first person_character bp

[lofty rapids]

so you just use flashlight active, how do you know if it's picked up or not ?

but you could store the class name and just spawn it if it's an actor

[spring osprey]

picked up what? the battery or the flashlight?

[lofty rapids]

your input just switches back and forth, what if you don't have a flashlight, do you get none ?

i don't see where it knows if you have it or not

[spring osprey]

oh the player always has the flashlight

[somber elbow]

I have made just another collision box specifically to score points. And make it to be deleted after overlapping and counting. Exactly what you said

[lofty rapids]

so you want to save the batter life ?

[lofty rapids]

you can think of the game instance as just some variables that you replace the ones you use with the game instance variables instead

so your pulling from the game instance

because everything else reloads

first thing is to create a variable in the game instance

[dark drum]

Ah ok, I would put the spawn tile to after the first sequence path and the delay portion, leave on the second pin but swap out the delay for a retriggerable delay. I believe that should give you what you want.

[spring osprey]

I want to make the game to remember in this case what life/battery the player BP had in the previous map

[lofty rapids]

you understand variables ? your using a battery variable

[spring osprey]

something like this or

[zinc spear]

I have a pawn whose capsule collision simulates physics, im trying to get it to rotate with the floor angle but the constraints on the physics tab mess it up. Keeping it enabled prevents it from being rotated as needed, but enabling it causes the physics to have influence on it. anyone got any ideas?

[lofty rapids]

yes and then in place of your battery variable use the one on the instance, and when you load the next level it will be the same because your pulling from the instance

in order to get that variable you need the reference to game instance, then you pull off that get/set

i normally do the get game instance casting in begin play

use that reference and drag off of it to use variables, functions

[zinc spear]

this is what i mean; when disabling the constraints i get this, i just want the capsule to stay upright but still follow the floor angle

[spring osprey]

and how can I change the battery variable I had in my character to use the one in the game instance? like this?

[lofty rapids]

ya exactly, replace where you use the other variable with the game instance variable

it will persist

[spring osprey]

it shows this error and doesn't work the flashlight now

[lofty rapids]

you need to actually set the game instance by doing the cast that i showed you

thats just an empty variable

on beginplay get game instance, cast, promote to variable, then use that variable

or just use a set and use the one you made

notice when you had player ref, you need a ref to the instance

you must have "set" player ref at some point, it should be similar

[spring osprey]

like this?

[lofty rapids]

right and use that variable

when you pull out and get the variable

as long as the begin play is in the same bp

[spring osprey]

did that but the drain battery now doesn't work

it doesn't show any error tho

[lofty rapids]

so what does it look like now ?

it's probably something in the logic maybe your still using the old variable ?

[zinc spear]

kinda works but not really lol

[spring osprey]

tried changing the battery variable in the hud also to try to fix the error but now shows this error too, also added the max battery to the game instance

[lofty rapids]

your setting battery not the game instance battery

[lofty rapids]

your instance still isn't there for some reason was the begin play on the same bp ?

[spring osprey]

this one is in a widget blueprint for a progress bar in the hud

[lofty rapids]

so you need to get the game instance again with a cast when you set it

i would just put the whole cast thing in the function

or you might be able to use construct

how often does get percent run ?

[spring osprey]

okay did that and fixed the error but the drain battery still doesn't work

[tranquil lagoon]

I have this really weird bug. When I possess another actor, all of my UI, Post Processing, Interaction Traces (Actor Component) still seem to be firing.
For example, my trace I have set up firing on tick from the player manager camera, fires on the new actor now instead despite not having the components for it!

If I destroy the previous actor (with an Event Unpossesed -> Destroy Actor) then all of that dissapears and everything works like it should.

However, I want to keep the actor in the world for a while because I want ragdoll. So what is causing this to happen? 🤔

[spring osprey]

might it be because of this set battery here?

[lofty rapids]

notice how your setting a different variable

the battery one off the inventory your subtracting from

but your setting the one in your bp, not the instance

[spring osprey]

Okay did a set battery in the as game instance and now it works and saves in the next map : D

[spring osprey]

so for the inventory should I do the same as the battery?

[lofty rapids]

save a backup then try it and see

https://tryitands.ee/

it should work with any variables you want to persist

[spring osprey]

it shows this error :/

[lapis oracle]

Why i cant connect them ?

is there a way to connect it ?

[dawn gazelle]

You're trying to set the Inventory Map on self but it's expecting a GI_Inventory reference plugged into the target.

[dawn gazelle]

Not sure why you would want to multiply a transform. That's a lot of unrelated data that wouldn't make sense to multiply.

Location, Rotation, Scale.

Multiply all of them all at once?

[lapis oracle]

im following a tutorial

[lapis oracle]

also this is exposed but for some reason i cant get it

[lapis oracle]

Does this make sense ?

[spring osprey]

fixed that error but even though it just doesn't work :/

[lapis oracle]

Any ideas on how to fix my issue ?

solutions?

[undone sequoia]

how to get random location in the air ?

in some radius 😄

[lapis oracle]

idk

[lofty rapids]

if you want to set it then drag from the ref and set the variable it should auto set the target

but your target is most likely the game instance

but drag it out and search "set variablename"

you want to use that set

[lofty rapids]

looking online there is actually a formula for this

[lapis oracle]

Is there a dead end for learning blueprints? how much time will take to fully learn blueprints

[thin panther]

you never fully learn

you are always learning

[lapis oracle]

BPS?

[thin panther]

anything

to get comfortable enough to make a title to ship that has a chance of success, that generally takes over a year of practice.
To give a title a really good chance, people often gain industry experience and stuff first. Most of the indie games you've heard of were made by people that once worked in the industry.

Of course you don't need to, no one does, it just takes practice, which takes time.

It took me about a year and a half to get comfortable with blueprints and how to use them

[lapis oracle]

Why did it take a year? do you keep watching tutorials for a whole year?

[thin panther]

Nope, you just make things

[lapis oracle]

Learn and then practice ?

[thin panther]

it takes a while because it's programming, and thats hard.
You've not only got to learn engine specifics, but fundamental skills

[lofty rapids]

programming in general is extensive thing and unreal is complicated really like anything once you know it its simpler

[thin panther]

You've got to learn how to break down your problems, come up with solutions, express it in the simplest form, often times with no resource to guide you. On top of this, you've not only got to learn how to adapt things to what you want to make, but also learn what nodes do the job, and the various blueprint pitfalls. That takes a hell of a long time
once you do things enough you get a feel for it.

It's always important to know why you're doing something though. Blindly clicking through or watching any resource won't help you, you will learn nothing.

[lofty rapids]

but the basics of bp you can learn quick, i would say like most programming goes you can't really remember everything and there is always something new popping up somehow

and so many ways to do one thing really

[lapis oracle]

I prefer watching tutorials and understanding it over copy paste, is that a good thing or i should change it?

[thin panther]

it's a good thing, but make sure you are understanding it.
people conflate it working, with understanding.

if you watch an inventory tutorial have you actually learned what an inventory is at it's core? Have you learned why the tutorial author designed the system in a certain way. Can you spot things that weren't so great, like using hard refs to store a texture icon, or using a massive datatable for all the items in the game, again full of hard refs

[lapis oracle]

yea i have heard about hard/soft ref, its important and interesting

[lapis oracle]

The massive datatable is a bad thing?

[thin panther]

if it's full of hard refs yes

[lapis oracle]

What if it is full of soft ref

[thin panther]

when you reference on row of a datatable, it loads all rows and all dependencies

[lapis oracle]

ow

[thin panther]

Not bad, I still personally prefer Data Assets though

[lapis oracle]

every asset has its own individual data ?

im asking lot of questions 😅

anyways do you have any good source to learn bps

[thin panther]

a data asset is a specific kind of asset

[lapis oracle]

ow

[thin panther]

make small projects to completion, then if you need a reference, MathewW is great.

You're not in error, it's a correct image, my brain just refused to read it properly :P

[spark steppe]

yea, it could be phrased differently to be easier to read/understand on the first read

[thin panther]

I mean just to clarify that I understand it?

[sweet imp]

Hey guys, so I am trying to make an enemy move continually towards the player, I do this but rapdily firing off ai move to calls and this works fine as long as the enemy can reach the player. One problem I'm having is that as soon as the player is in a place where the ai can't reach, even just on top of a tiny rock, the ai will stop moving. I'd rather them still keep moving towards the player even if they can't reach them. I could probably brute force this with some logic that makes them go straight in the player's direction if the ai move to fails or something, but I just wanted to know if there's a way to do this with ai move to or some other node instead? Thanks in advance for the help!

[warped forge]

Hi! I've been trying to attach an apple mesh component to a tree mesh component into a socket, using add static mesh compoent node and attach component to component node, the later node's return value is true

I've created the socket, the apple appeared in the right place, but when I try to get attach socket name on the apple , I always get None
Also, when i call get all children components on the tree mesh component, I always get no children.

am i doing anything wrong?

what i'm trying to do is when the apple mesh got hit, the apple will be detached and new apple will grow in the detached socket

[spark steppe]

no, i think your code should be fine

can you show the other nodes where you try to get the child components and the socket name?

it's possible that the whole socket stuff only works on skeletal meshes

since for static meshs it's just a... static transform

[warped forge]

Sorry I am away from my computer
I tried two places to print apple mesh's get attach socket name
1.right after the attach component node
2. In the apple's on hit delegate

Both of which output None

[lapis oracle]

Why i cant connect them?

The tutorial im watching

[spark steppe]

search for compose transform

[warped forge]

If this is it, does that mean I have to turn the tree into skeletal mesh?
Maybe I should try some workarounds like turn the apple into BP and store the socket name into variable, but this feels so cumbersome

[spark steppe]

i would rather create a Map on the Tree Blueprint, which stores a reference of socketname <> mesh component

it's a bit more work since you have to add/remove the apple mesh mappings every time you add/remove an apple, but i would use that approach over a skeletal mesh for sure

[warped forge]

Good idea, and I'll manage the map

[spark steppe]

static meshs are way more lightweight for rendering

[warped forge]

Thank you so much

[lapis oracle]

wait i thought that was a multiply XD

Tysm

[spark steppe]

also since you watch a tutorial... connect them exactly like the author did

since the order of operation is important for composing transforms

[lapis oracle]

this for some reason doesnt connect too

[spark steppe]

because you have a mesh reference

you need a skeletal mesh component reference

[lapis oracle]

i exposed this but for some reason i cant search it

[spark steppe]

hold CTRL and drag the variable on the graph

[lapis oracle]

where do i get that ?

[lapis oracle]

its in other bp

[spark steppe]

you wont get variables from other BPs, unless you have a reference to an instance of them

guess there's a bunch of tutorials ahead of you 😄

[lapis oracle]

fr, any good tutorials ?

[spark steppe]

[trim matrix]

NICEW!

[steel star]

hmmm. sooo, are there blueprint class 'instances' that exist as assets so that i can assign them to properties in the bp designer without having to find some place to allocate them? what i want is just the bpclass with its default values

right now im doing some annoying shuffling by having the property be a class ptr, then allocating the actual object in the construction script

[lunar sleet]

afaik, only if you place them in world manually

otherwise instances don't exist pre-runtime

[spark steppe]

doesn't get class defaults work on a class reference? (i think it does)

@steel star

[lunar sleet]

that's what he's doing currently no?

[spark steppe]

no, he is currently creating an object instance from the class

[lunar sleet]

ah

[spark steppe]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Class/GetClassDefaults/

[steel star]

ive done both.

the team keeps some state that isnt really safe to be in the default object though, im pretty sure

like a TArray<AShip> of all that teams currently living ships

[spark steppe]

oO

[steel star]

er. UTeam is the thing ive been talking about with Class vs Object ptr

and actually uteam will ultimately need to be an actually replicated object

so this is all kinda just a short term hack how i have it atm

well, how it was

now that i am allocating a real object that gets held onto by the gamestate, it actually should be fine, imma just not touch it again until i have to

[lethal ocean]

Hi! I'm having this weird issue where I'm trying to set the global time dilation to 0 and pull up a widget right after. For some reason, the Set Global Time Dilation node is being completely bypassed. It runs the blueprints before the node, and creates the widget right after, but dilation still isn't getting set. What's going on?

[lusty shard]

How might I go about making it so an actor contains its own buttons and adds them to HUD element when selected. Already have selection working and when buildings are selected, they all have Cancel and Recycle option. But I want one garage building to have "Make Vehicle" option for example.

[faint pasture]

is 0 a valid time dilation really?

[lethal ocean]

Yeah, I was calling it before but needed to move the code to its own function/custom event

It's only stopped working after I moved the code

[lusty shard]

How might I go about making it so an actor contains its own buttons and adds them to HUD element when selected. Already have selection working and when buildings are selected, they all have Cancel and Recycle option. But I want one garage building to have "Make Vehicle" option for example.
potential to have unique button options for each building.

[dawn gazelle]

In your base "building" class have a function called "GetSelectionOptions" which returns some values you can use to then generate the options after you've clicked on the building.

You can override the function in each class if there's different logic required for what appears as well.

[faint pasture]

How does the widget talk to the building? What's the code path?

how do you tell the building "Hey, recycle"

[lusty shard]

Is there a best way for generating buttons from within a BP? I imagine id have to have a button as a widget compoent in the blueprint and duplicate that component for each option? Jus tnot sure how to go about this.

When building is clicked I spawn this BuildingInterface BP at the selected actors location, and store that selected building as the widgets owner.

Then, depending on the button clicked, within the widget event graph, I do things.

Widget owners could be several buildings.. so im allowed to have 1 widget placed at center of all selected actors. Click Recycle once, and that tells all those actors to destroy themselves.

[faint pasture]

so how will a widget call MakeVehicle?

You might want to encode it more as data.
Building.PerformAction("Recycle")

[lusty shard]

Good question. this is where im at though. Somehow this widget needs to be aware of that option that has been added to itself.

[faint pasture]

I think you want an enum or names or tags for actions

Then you'll have the array of things to pass to the widget

[lusty shard]

hmmm

[faint pasture]

and you'll have the data to pass to the building in PerformAction, then the building can switch on it to do whatever

[lusty shard]

I could also store all the options here...

oy

[faint pasture]

I'd maybe use GameplayTags

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Tags/

[lusty shard]

alright thanks

I will have to look at this... There has to be a way to have a button contain its own actions... similar to how a component can contain its own logic. but I'll see how tags can work too.

off for dinner. thanks!

[faint pasture]

Building holds tags
Buttons for building are made using the tags
Button calls DoThing(tag) on building when clicked
Building switches on tag to do the right thing

How can I activate an ability till user pressed key and deactivate it on release using gameplay ability system?

[dawn gazelle]

Within the Gameplay Ability, there is a "Wait Input Released" node you can use, but it requires some additional set up if you're not using the antiquated binding system.

When Released -> End Ability.

[upbeat jasper]

Ok I'll try this thanks

[cyan spire]

Hello i have a question, is it possible to add my own logic for the context menu somehow?

Im tired of renaming it to local every damn time to not loose track

[lunar sleet]

not unless you modify the source code

[cyan spire]

Damn, so i need C++ for this right. already thought that

[lunar sleet]

and the engine source if you don't have it

[remote meteor]

you dont really have to, unless you are modifying it, function parameters can also be get-ed as though its a variable

[lunar sleet]

this is true, local is not really needed ig

[maiden wadi]

I do this with a set of data assets. Their class has some functions on it that are ran on each asset when things are selected and passes in the selected actors. Does different things when you're selecting multiples or singles, like some actions only show if you have a single thing selected. Only actions that affect all of the selected things will show when you have multiples selected.

Once that list of assets is filtered down, the remaining ones are sorted via a priority and then passed to a listview. OnClick an action function is ran on the asset by passing in an array of the things to affect. And since they're assets, I can gather them all easily through the asset manager. So all I need to do is make a new asset for a new action and set it up and the system picks it up.

[faint violet]

Is there another way to pass through spawn data with blueprints? Because I have to use a delay, as the bp interface call takes 1 tick to activate.

[frosty heron]

I don't see why you need the delay there at all.

You want to destroy the actor when the damage occur anyway. As for your Spawn Params, you can expose them on spawn if you need the data to be readily available.
There is also Spawn deferred afaik

[lusty shard]

You just said so many things that made me feel like a noob at unreal.
1.) what do you mean by "once the list of assets is filtered"? I am not aware of any list at this point.. you mean the list of actors that have similar action functions vs not? List view?! Your exporting actors into a list?
2.) Clarity on Action Functions? Is this different from a usual function?
3.) Since (things to affect) are assets, you can gather them all easily through the asset manager? Is this the same as world outlined?
I need screenshots or something lol feels like you're talking about an entire section of unreal that I don't know about.

Probably better to DM me on this if this is long winded. We are friends already I believe

[maiden wadi]

It's nothing complex. Data Assets are just classes meant to house data. But they can also have functions on them. And the AssetManager has functions that allow you to pull all assets of a type without manually specifying it into some array somewhere.

The Data Assets are meant to contain the functionality for an action. In one class, I have a function that takes in an array of actors which checks through these to make sure it can affect all of these actors. If it can it gets passed to the Listview.

Listview is a widget that creates a widget for an object. You can do the same thing with a vertical box and making a widget to put in it. Listviews just handle easier and perform better. Recommend checking them out.

So when you select actors, you gather up the Data Assets that represent your actions. Recycle, Cancel, Build Vehicle, etc.

Iterate through them by passing in the array of actors selected to filter them into a new list. EG if you click on something that doesn't build a vehicle, it would return false so would not show in the list.

Once you have all of the available actions, you pass them to the listview or the vbox and make widgets for the actions, probably buttons usually. The assets can contain the text necessary.

When you click on a button, it passes the array of selected actors into a second function in the selected data asset which does the actions. EG you click on recycle. This would try to recycle the buildings.

It allows you to create expanding lists of actions without the need to do any sort of hard coding or mass amounts of branch switching etc.

So in the end once the system is set up all you need to do to make a new action is.. Program the action itself to work. Using recycle as an example you'd program that into your buildings of course. Then create a Data Asset class for the Recycle command. Override the two functions. And now recycle shows in the list of actions once you create an instance of that asset.

[lusty shard]

You've just given me homework for a week. I have so many questions.

Thanks!

[lunar sleet]

I didn’t realize DAs could be used for this

[scenic stump]

Hello, Im kinda stuck trying to trigger AnimNotifies to toggle a bool to trigger mirroring of an animation. It prints ItsWorking! but never LeftAhead! or RightAhead!. The animations triggering this is in a blendspace. Im assuming Im missing something silly.

[maiden wadi]

You can use basic UObjects too. But not in BP. At least not without instantiating them manually into a list. In C++ you could get their CDOs to run the logic on and pull data from. But DAs are a bit more BP/scripter friendly in this regard.

[frosty heron]

Can I ask how to get the CDO in cpp?

Static class is not CDO?

[maiden wadi]

SomeClass->GetDefaultObject()

[frosty heron]

Ahh okay

[maiden wadi]

Worth the warning. Do not set state on any CDO that you plan to create instances from. The instances will be affected by this as well and it's considered bad form. The only useful thing I've found to change on a CDO a UWorld pointer, so that you can use World required functions in a BP child of that class. Like...

SomeClass->GetDefaultObject()->CurrentWorld = Getworld();
SomeClass->GetDefaultObject()->SomeBlueprintNativeOrImplementableEventThatMightHaveNeededPreviouslySetWorld()

[frosty heron]

Totally sound like static class that has static variable. I know it's not but I am just a little confused as I'm very new to cpp.

But I will keep that in mind. Tyvm

[scenic stump]

Testing an notify bp class instead. Seems I cant cast to the linked anim graph that plays the animation. I get fail on first cast and success on second cast.

[maiden wadi]

ABP Movement isn't a parent or child of the Character ABP then. Where did you specify it with the expectation that it would run on the character?

[scenic stump]

ABP_Mov is child(linked anim graph?) of ABP_PlayerChar, the events in the screenshot earlier was defined in Abp_move so I assumed they would fire from the animation that abp_move played that had the notifies defined. If I use tag on Abp_move and cast in the notify_bp it works.

this gets Abp_move success triggered.

Id love to understand what I was doing wrong with the first case. Should the events be defined in the parent of the linked anim graph?

[faint pasture]

What is a linked anim graph?

I'm not sure that's a subclass

[frosty heron]

it's a node in anim blueprint

[scenic stump]

Whats the workflow to trigger notifies here? so far using cast with tag was the only thing that worked in the notify blueprint.

Okay so putting the events in the root anim blueprint seemd to work.

But then what the heck are these supposed to do? They are set to off for me. confused

the checkboxes for notifies from linked etc.

TLDR: the Notifies in the walk animation played by the linked anim graph gets triggerd by the Animation blueprint that has the node for the linked graph, no matter what settings the linked graph has for animation notifies. They are NOT triggered in the linked graphs events. I have no idea why. shurgs Posting this if someone else has a simliar issue in the future and searches.

[surreal lotus]

HELLO ALL!

I've a very stupid replication issue I believe, I am following a simple tutorial to do a line trace that uses Apply damage function on the server.
I've attached the very simple bps

But now when I compile and run on a 2 mutliplayer setting (New editor window or standalone game)

When I do the line tracing, I get the error, No owning connection for the actor: Function Server_ApplyDamage will not be processed (ive attached the screenshot).

can anyone please let me know what is it that I must do different or anything

Thank you all!

[frosty heron]

Why would you use legacy damage system

Anyway your issue seems to be related to ownership.

You can't call RPC as client on actors you don't own.

Hence the error msg

Multicast is used 95% of the time for the wrong reason btw.

Only thing you should multicast here is the anim and the sfx

[surreal lotus]

I see, thank you, I saw similar threads regarding ownership so I will try that

[frosty heron]

As client you can only call rpc on what you own. Eg your controller, player state, and your pawn.

You can pass ownership ( set by server ) but let's not go over it. It's not really good practice afaik.

If I can give my 2 cents, don't use legacy damage system. It's ancient and meant to be removed in 5.0 but got delayed

[surreal lotus]

Thank you for your advice, really appreciate it, I’ll knew that in mind

[frosty heron]

@surreal lotus btw from reading the code, seems like all you have to do here is to pass hit actor to the damaged actor

Unpin that hit actor cast, and plug the hit actor to the damaged actor. See how that go.

[bright hamlet]

Cold, I’ve sent you a DM when you have time if you don’t mind helping me with a question or two 😅

[frosty heron]

Ask here mate, so others may help you as well.

I mostly only pretend to know something.

[bright hamlet]

It’s regarding that old system you talked about, which one did you mean the AnyDamage or?

Dumb me don’t know what’s “old” and what’s new haha 😂

As I’m quite new to this field overall

[frosty heron]

Unreal has this legacy damage system. The one where you call apply damage.

That goes as far as unreal tournament afaik, most people don't use it anymore. I prefer to roll my own as well.

2 things I won't use are the legacy damage system and the legacy input system.

[bright hamlet]

Enhanced inputs yes but as far as dealing dmg you go with GAS or?😅

[frosty heron]

GAS

But I just start my self

[bright hamlet]

The nightmare for a non coder 😂

[frosty heron]

No AI, no combat

I'm working on aiming system

[bright hamlet]

Which is what I need 😂 but so far doing it without GAS

[frosty heron]

GAS is too good to be ignored. Especially if you are doing multiplayer game. It has in built replication stuff.

It is the system used for fortnite

[bright hamlet]

Oh I know but the tutorials for it are so 🫠

[frosty heron]

At best you can make turn based game with blueprint, is my opinion

If my only tool is blueprint to make multiplayer game that needs to address latency, I will give up and make single player game instead.

I'm in tutorial hell my self, currently watching Stephen ulbardi multiplayer tutorial in udemy

[bright hamlet]

So far the combat (directional) is working but there’s so much more to add 😜

[frosty heron]

Did you test with latency?

[worthy jasper]

was watching a video on a game releasing on steam that’s multiplayer, mostly blueprint from what he’s saying and wasn’t a turn based game

[frosty heron]

With blueprint you can't extend character movement component.

[worthy jasper]

Blueprint isn’t all bad lol

[frosty heron]

You also can't do server rewind

[bright hamlet]

Only “playing” with myself and AI (as client/server) but not with other players

[frosty heron]

The lack of feature is just make it impossible to make smooth fast pace action game

[worthy jasper]

I’ll disagree tbh

[frosty heron]

Well that's not how to test mp

[worthy jasper]

Yeah some things you want C++

[bright hamlet]

It’s not gonna be a fast paced, not like mordau or chiv and def not like slow ass Mortal Online 😂

[bright hamlet]

Enlighten me Master!

[worthy jasper]

Use blueprint for what it’s for. Prototype and get it working. You can convert to C++ later if it requires it

Keyword IF

[frosty heron]

Add players when playing in pie and add latency using the console command

Net.pktlag 400 or something like that

[bright hamlet]

Players like randoms to test it or just more players (that I control)?

[frosty heron]

Players that you control

[bright hamlet]

How many? 😅

[frosty heron]

Play the game with multiple clients

Normally 3

[bright hamlet]

I usually do with 3

[frosty heron]

1 listen server and 2 client is a good test

[bright hamlet]

But without the latency thing

And combat is 🙏

[frosty heron]

Introduce one otherwise its fake multiplayer

In real world there is no 0 latency

[bright hamlet]

I usually keep 1-2 besides the client I run to make sure things replicate and works for server and client so just add the latency and test it again then

[bright hamlet]

Im gonna have to do that to make my own server build thou I suppose but not yet, I need a tutorial for that as well as the one I followed I can’t find anymore 🥲

[worthy jasper]

Dedicated servers? Not even. It’s one file

[frosty heron]

My only regret is not learning coding earlier. I'm only a few months in but happy to achieve what I can't in blueprint

[bright hamlet]

For the project not the server

[bright hamlet]

The server thing I can manage but somehow I can’t figure out how to compile my project to a c++ like I did before 5.4 (in 5.3)

[worthy jasper]

Yeah for dedicated you will need a source build

[bright hamlet]

Which I have 😅

[worthy jasper]

Half way there then XD

Like converting it to c++ or compiling it?

[bright hamlet]

Like I told my hobby dev friend, I don’t need the server and a lot of stuff yet but I rather have them working right away 😂

[frosty heron]

That's nice, I can't figure out how to make dedicated server yet

[worthy jasper]

Yeah I hear ya

[bright hamlet]

Converting it so I can thinker with it in Visual messed around in 5.3 when I touched Gas

[worthy jasper]

Dedicated servers are pretty easy to build

It’s just a diff build target

[worthy jasper]

Oh ok, yeah just need to make a c++ class in the engine

[frosty heron]

Ye but I'm trying to wrap my head on how to execute the .exe in the game then connecting to it automatically.

[bright hamlet]

That’s all? Not remove the saved and intermediate files? In the project or that’s after it’s compiled but before you generate the files

[worthy jasper]

You don’t? Unless I’m not following

[worthy jasper]

Nope, just make a class

[frosty heron]

My idea of dedicated server is to let player host the game as dedicated server.

[little cosmos]

Crash! What's this?

[frosty heron]

I'm not opting for Web services, no money for that

[surreal lotus]

Cool, I’ll try that and see if that works and let you know

[worthy jasper]

Oh. Well then they would just download your dedicated server and run the exe

Port forward and what not be up to them

[frosty heron]

No one wants to do that lol

[worthy jasper]

That’s how it’s done

If your putting it on the players

I guess you could make a fancy auto find thing

In your game

[frosty heron]

I want it like l4d and they can chose dedicated instead of listen

And the only sole reason is because animation breaks in listen server

Otherwise I won't even bother with dedicated

[worthy jasper]

ah so your trying to just within game launch a dedicated server in the background?

Interesting

[frosty heron]

Yup pretty much

[worthy jasper]

Unconventional but hey why not

[frosty heron]

There is always a way, I just feel like I'm jumping too early

Rather focus on the gameplay for now

[worthy jasper]

TBH I’d just do what most games do

Package the server with the game

And add a launch argument in steam for example

Palworld is the most recent one that comes to mind

They have multiple play options

[frosty heron]

0o

[worthy jasper]

One of them launches a server the other launches a client

Then in game you just enter an IP

[frosty heron]

What the heck

Surely they have server browser?

[worthy jasper]

For official servers yeah

[frosty heron]

I see

[worthy jasper]

And there is a setting they are testing for auto discover

So like if a player hosts there dedicated server they can choose to add it to that list

[frosty heron]

👍

Oh well my plan is still to use steam, run dedicated server headlessly without the console and have the player joins automatically after the server is made.

A problem for another day

[worthy jasper]

Yeah def doable

😄

[frosty heron]

Just have to sacrifice more grey hair

[worthy jasper]

I mean that’s basically what unreal does when you hit play as client XD

[spiral kite]

When I activate set simulate physics, my character goes into the ground, does anyone know what is the reason for this?

[frosty heron]

did you disable collision anywhere?

[spiral kite]

no

[frosty heron]

then I don't know

I'm gonna guess that your skeletal mesh collision is not enabled

when you move around by default, you are using the capsule component collision

[spiral kite]

Im gonna check it

ty

[frosty heron]

but when you simulate physich on the skeletal mesh, you should enable the collision for the Skeletal mesh and let Physic assets collider handle the collision

[spiral kite]

I activated it from here but it still enters the ground

[graceful sage]

check the collision of the actors in the level also. and the characters mesh

[frosty heron]

Check your Skeletal Mesh Component

[frosty heron]

If you read, it says no Physich collision Enabled

[surreal lotus]

Just tried, this and it worked like a charm

thank you so much

But can you maybe elaborate why it worked this way im still a bit lost

i get that i cant call an rpc on sth i dont own

[frosty heron]

Remember that Server RPC is the only way for client to communicate with the server.

So as client, you want to execute server RPC, passing the data (eg the actor you hit and the damage caused (self))
Server then receive the Data -> Applying damage to the hit actor that you pass.

Behind the scene, the server will call Event damage on Damaged actor which runs on server. In here you can set the health or w/e. And since replication work from server to client, the Health of clients will be updated on the next network update

so what you are missing in your earlier screen shoot, is you didn't pass the damaged actor to the server

this way server doesn't know, who to apply the damage to. (Which is required for the event damage to be called on the damaged actor)

[surreal lotus]

Perfect, this clears so much stuff!!

Thank you so much again

[frosty heron]

also in the event Any damage, pretty sure you need to set the health variable of the character that have its any damage event executed, not the damage causer health 😄

but perhaps you already fixed that

[surreal lotus]

oh yes yesi think that part was missing in the screemshot, but its there

the updates are happening as i want

!! thank you

[last pier]

Hello!
I'm trying to implement a voice system with VOIP but I'm having a lot of trouble, would anyone know how to adjust the microphone sensitivity please? I've tried with set mic threshold and several commands but without success...

[dreamy mountain]

Hey, so I'm trying to make it so my ai enemies can fall off of ledges, how would I do that? They're set on an AI MoveTo set to my characters location, but when I jump off a ledge onto a lower ground, they have to use stairs; how would I make it so they too can just walk off this ledge

It's got a nav mesh which is on both the high and low areas, and there's nothing to stop them walking off physically, they just prioritise stairs, and if there's no stairs, they freeze and can't get to me

[gilded jewel]

anyone know of a way to add a branch referencing each array element, so as it loops it will do a different specific action based on a bool of each ?

[real notch]

I have a physics constraint that spins (wheel). How do I add some friction so it doesn't spin for eternity?

[real notch]

Foreach loop body pin, the array element is the element. So loop body to branch, array element's bool to branch as well

[gilded jewel]

thanks, only problem is the array isn't bools

Ive got seperate bools for each to reference later

[real notch]

I don't know what you mean. I see a bool in your screenshot, and it's attached to the branch.

And the branch is in the loop body

So it'll run for every element

[gilded jewel]

oh yea, but that is where im stuck, i want to set a variable for each array element, but its different for each one. so true at the end would set a bool for free flight btn, or hover course btn ,, dependant on which one was in focus

so i kinda want to reference the array position i guess ?

[real notch]

Idk if it's a language barrier or something, but I have no idea what you're asking sorry

The position is Array index

[lofty rapids]

so you have seperate booleans not attached the elements in the array that you want to use ?

[gilded jewel]

yea, relevent to each array element

[real notch]

So, that's also an array?

Then array index

[lofty rapids]

you could just two arrays and the index to match them

so index 1 would link to index 1 of the boolean array so you would know which one to use

you would need them to be in a specific order

[gilded jewel]

ah.. i can easily set the same order .. im not quite sure how to set this up.. one sec ill try before asking lol

[real notch]

This makes so very little sense to me :p

If you need a different chain of operations for each, don't use a loop

Or, if they're actors, give them an interface to implement

That way you can just call a method, and each of them can implement their own logic

[lofty rapids]

interface ftw

[gilded jewel]

i think your right, my method is a little convoluted , they should each be checking and running this within themselves really

it was a quick easily solution, until i started to add more to it

[lofty rapids]

an interface would work well most likely because you just call a function on the item in the array, and you can handle them all seperately in there own bp

[gilded jewel]

i did this, but is there actually a way of setting a bool from here, without a direct reference to it

Yea i think ill have to backtrack and do it that way very shortly

[marble tusk]

Even better you could just plug all 4 refs directly into the function and it'll loop over all of them automatically without needing to use a foreachloop

I think as long as there's no return value

[trim matrix]

Anyone know how I can have it so I can select a box collision like you do with the pickwhip thing ?

I have that actor

Sat within another actor and I want to set the box collision to the one thats in the parent BP you could say

[real notch]

What's a pickwhip

[trim matrix]

so like if you have instance editable variable say on an actor in the would you can click the pickwhip and click valid object in the world

[real notch]

I googled it and I still don't know what a pickwhip is

All I find is after effects stuff

[lofty rapids]

if it's in the parent bp, can you not use an event for when you overlap that box ?

i would think the child would be able to have an event for overlapping that box ?

[trim matrix]

no so the logic is on the door actor itself

[lofty rapids]

but idk that for sure

[trim matrix]

the child actor at runtime I want it to grab the box collision thats been set and bind to it's on overlap

the bit I'm stuck on is how I can expose the box collision variable in a way where I can set it from the parent BP to the box component I want it to be

[dry sleet]

I assume eyedropper/pipette in this context.

[trim matrix]

thats the one

[real notch]

Half of the stuff I see in here is unreadable to me. Yet somehow people seem to understand each other. It's wild

[dark drum]

I feel like that when I go to the c++ channel lol.

[quartz field]

Hi, are there any side effects I should watch out for when using the 'collect garbage' node? Using it solved an issue where an input function was still triggering in my widget BP even though I 'removed from parent' and cleared the reference to the widget, but i'm wondering if 'collect garbage' might have some unwanted consequences

[real notch]

That's a whole different level of illiteracy: nerds

[real notch]

I think you need to just disable the widget instead

Remove from parent and forcing GC after is a bit of a nuclear solution I think

The unwanted side effects could be a stutter, depending on how much garbage the engine collected

[quartz field]

gotcha, thanks!

[sharp python]

😦 Every time I restart UE5, it blanks the contents of some data table properties in my character class. Because there are about 20 child classes, this gets really annoying to fix every time. What is going on?

[real notch]

Are you using c++? Does the restart happen gracefully? Is everything saved in between restarts?

[sharp python]

I don't know if everything is saved, but I think it happens whether or not UE5 crashes. I'll test this, because I can't remember when I last shut it down without it crashing. This is a blueprint class with some data table properties in it...

[real notch]

Lastly, maybe it's just corrupted and the best thing to try is create a new one from scratch and see if it still happens

These are all the reasons it has happened to me before, but there may be more.

Oh, yes, one time I forgot I had changes and reverted VC but that hardly counts.

[sharp python]

Replacing the base character class might, uh, take a while. 😦

[real notch]

I believe that

Don't you have a working version in version control you can go back to?

[sharp python]

Yes, but I don't think this happened recently

Update: it happens every time I close and restart the editor, and ONLY with the data table properties in the base class; the ones in the child classes are fine. 🤔

I'll try copying those specific properties...

[real notch]

I've had corrupted blueprints before. Nothing worked for me, except recreating it

[sharp python]

😭

[real notch]

It also happened because I was using c++ and live coding

Two separate things

Maybe it's not it though. I say stupid shit a lot

[spring osprey]

Hi, can someone help me on why my outline post process volume doesn't work?

[lunar sleet]

Live coding = good. hot reload and reinstancing = bad

[sharp python]

Status update: I made another property similar to the ones that failed to save, and set it, and this one survives a restart

So I just need to replace the properties, not the entire class... 😐

[swift kiln]

Hey I want to make a simple system that works like this: When certain actor is in a specific collision box, a timer starts lets say counting to 10. I was thinking to make code in event tick so when the actor is in the collision box, timer goes on, but when it goes out of it, timer saves and when actor enters it again, the timer continues from when it was left on

[pine moth]

im trying to make that after player picks 1 actor all enemies start chasing the player so im using get all actors from class but dont know how to do it

[real notch]

I have definitely had issues with live coding. I just recompile from my IDE now.

[real notch]

Have fun 😄

[swift kiln]

It cannot be that difficult right?

[lunar sleet]

If those 2 options are checked (they are by default), then yeah LC will trigger a HR. But either way if you’re changing cpp classes you should do it from IDE with editor closed

[real notch]

I run the editor from my IDE, so changes is just shift+f10

Big brain move right there

[lunar sleet]

Prly the best way to run it anyway

[real notch]

Sounds pretty easy

Should something happen when the timer reaches 10?

[lunar sleet]

Simple

[real notch]

In any case, you don't even need a tick

[lunar sleet]

Will the actor ever spawn inside this collision box?

Or always enter it

[swift kiln]

No it wont spawn in it, it can enter and exit out of it whenever

[lunar sleet]

Ok then easy

OnBeginOverlap set timer by event, delegate to custom event, increase integer. Promote timer handle to a variableOnEndOverlap, clear and invalidate timer handle

[real notch]

They weren't challenging you to do it, let them figure it out themselves lol

[lunar sleet]

The int will be saved.

[lunar sleet]

Generally people come here for advice

Not necessarily to announce they’re doing something

[swift kiln]

Yeah thats what I did

Anyways, thank you

[real notch]

See, then ask a question. That wasn't a question 😂 I give up

[wild laurel]

Begin overlap will not work as u expect

[swift kiln]

Well I mean I came here for something I didn't want to be just cheered up

[lunar sleet]

You can do it with tick too but timer is prly better in this case because you don’t need to run it 120 times a second

[wild laurel]

U should do this on tick in conjunction with a set timer by function imo

[lunar sleet]

Also nothing wrong with using overlap events, collision is just a tricky lady and some people give up on debugging too early

[wild laurel]

Just make a function that increments by 1, then set timer by function off begin play to loop every 1 second, then on tick check to see if actor is inside ur collision box, if not then stop the variable handle timer

There is something wrong with overlap if u enter and leave and enter too fast it doesn’t keep up

Needs to be on tick to function properly

If u test overlap enough you’ll realize it should only be used for things that only need to overlap once then die essentially

Such as a bullet or something to that effect, imo it’s not for things to go in and out over and over again

[lunar sleet]

There are ways around that.

[wild laurel]

Tick wil never fail, and ppl overthink performance. Ur entire game is a tick.. u need to use it

Especially since it sounds like a critical component to his game

[lunar sleet]

This isn’t about perf but alas if memory serves arguments are pointless here

[grave relic]

Hi!
I'm following a tutorial on the internet from a guy, and he has the "ADD" option on Inherited interfaces and I don't, is this a bug or not? I'm sure I did all the steps correctly. For my part, the two options are reversed!

[lunar sleet]

What engine version ?

[grave relic]

Latest

[lunar sleet]

I’ve seen that before, it’s a graphical glitch where the 2 are swapped. But I could’ve sworn it was fixed as of 5.3

Oh right that makes sense

His engine version is older

You would not normally ADD an Inherited interface

It’s inherited

But back in 5.1 or 5.2 the wrong one had the button

Only aesthetic tho, the Add does the correct thing of adding an interface

[twilit granite]

I am trying to load a asset from a PrimaryAssetId, why it is not working?

[lunar sleet]

Yeah the button is just in the wrong spot on the UI on his engine version, but it’s the same thing you have

Yours is displayed correctly

[grave relic]

Oh, so it's the good button, it's just inverted by mistake

[pine moth]

how do i make boolean enabled for all enemies with get all actors of class

[lunar sleet]

✅

[lunar sleet]

For each loop Set Boolean True

[pine moth]

for some reason it gives every single error on delay note on the enemy blueprint

and says infinite loop detected

[maiden wadi]

Event Destruct can be used to remove inputs in the widget.

[maiden wadi]

Can you show the rest of the code to the left?

[twilit granite]

I just moved it to cpp, but it would be equivalent to this

[lunar sleet]

You cannot have delays inside regular for loops

[pine moth]

i fixed it

[pallid nest]

hey guys, basic and newbie question... why can't I add this variable to make an array when these are the same parent (character)?

[lunar sleet]

try creating an array variable with class type parent and then Add/AddUnique each of those to it

[pallid nest]

I tried so but for some reason it won't allow me to add any characters (it is greyed out)

[lunar sleet]

Not from there

Drag it into the graph

Then add those 2 refs

And hit compile first

[pallid nest]

mmm but how can I add these into my new variable (char)?

[lunar sleet]

I just told you

Drag the array into the graph

[pallid nest]

yes but I didn't understand sorry, none of these are compatible input/output :/

[lunar sleet]

Drag from Char, type Add

[pallid nest]

ohhh bless you

[lunar sleet]

Hopefully RPig and RDogo are not empty variables and you actually created those refs somewhere, otherwise this is a bit pointless 😀

[pallid nest]

would this be correct or do I first need to set char variable before adding a new one?

no no , it has a ref from a cast so it shouldn't be empty

[lunar sleet]

The char variable here is just an array, so you don’t need to set anything. But the 2 refs you are adding should be actual instances, and they are from what I can see

[pallid nest]

thanks for your help really appreciate it ❤️

[vivid quarry]

Does anyone have advice or sources for implementing something like this? It's very simple and intuitive on paper but I am encountering some roadblocks, the biggest two being making a charge-up animation revert to idle if the key is released early, as well as separating input for long and short holds (short hold begins charge animation, long hold sets charged state and primes attack)

I'm not sure what (if anything) to put on the AnimBP vs on the character BP. Typically I do all the attacks on the character BP as montages, but I'm not sure if it's worth making a state for the charge animation loop

[lofty rapids]

looks like a state machine, maybe use some booleans

i love me some booleans

[faint pasture]

how is the tap detected? Through inputs or through the montage?

[hidden cape]

Could anyone help here? Thank you

[faint pasture]

the charge -> heavy path should be doable as a montage

Input -> held? -> play heavy montage
-> tapped? -> play regular montage
-> released -> tell the playing montage

[gaunt monolith]

Hey everyone, i followed this tutorial to get an interaction system going: https://www.youtube.com/watch?v=dkeVrlRFJDk
The problem is that i'm in a first person project, and now the player can interact with the object as long as he's inside the collision, even if he's not looking at the interactable object. Is there a way to add it so that the players also has to look at the object to interact with it?

[faint pasture]

yes

Are you familiar with the Dot product?

or line traces

[gaunt monolith]

I am with line traces, i even tried adding that but couldn't get it to work

[faint pasture]

First off make this decision, do you want to select the actor within some radius that the player is most looking at, or select the one that they are directly looking at?

Does kinda looking at something work, or do you need to literally be aimed at it like Skyrim

[gaunt monolith]

I want to be directly looking at it, for example with a door, i want the player to be looking directly at the door to be able to interact with it.

[faint pasture]

Then just line trace on tick or a timer, and if you hit something, set that as InteractionTarget

then when you press your interaction key, call Interact on InteractionTarget

[vivid quarry]

I wound up getting it all done in a sort of strange way, but it's all in the character Blueprint (I personally like using AnimBPs as little as possible)

The formatting here is still mess and it's missing bools I will need later, etc, but it's just to see if it works. The input is set to a hold action with an arbitrarily long trigger time (10,000 seconds). So everything is done via cancels

[faint pasture]

Tick -> line trace -> did it hit? -> yes -> InteractionTarget = HitActor
-> no -> InteractionTarget = Nothing

E -> is InteractionTarget valid? -> yes -> call Interact on it
-> no -> do nothing

do it all in BP until you feel comfy with the engine, then consider getting into the C++ side of it IMO

[lofty rapids]

a blueprint tutorial and along the way put the stuff to use worked great for me i had experiencing programming but not with node

https://www.youtube.com/watch?v=6UlU_FsicK8

the beginning of this video is pretty good

after the landscape stuff it's about bps and how they work

[cerulean igloo]

Is it common at later Experienced stage to fully do it in c++ rather than node/blueprints ?

[cerulean igloo]

Thank you

[faint pasture]

It's always a mix

You can sort of think of the C++ stuff as backend and BP as frontend but that's not a perfect analogy

[cerulean igloo]

Doesn't take ages to do simple stuff with node? I always thought programming through a GUI rather than text (writing code as we now it) is much more time consuming

[faint pasture]

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

[lofty rapids]

i would do whatever you can in bp, and when you hit something that is performance better or only in c++ then use it

ok question

in ordeer to make my animations change i use booleans but i need to replicated the booleans from the client to the server

this is what im thinking

but its not working

[pallid nest]

hi guys i am trying to understand why is my array not valid (the goal is to custom event - attract in BP_Cube Grab)? I am simulating a code (copy and paste) that is working perfectly with another blueprint, the only difference between this code (that doesn't work) and the one that works is that my variable reference here is looking at a blueprint that is an actor class (and in the one is working is looking at a character class instead), any ideas how can I make it valid please?

This is how I am making the reference (Ref_Cube) and also the other bp that works (3_2_9_2_Pig). Something I did notice is that when I use a reference (simply get ref_cube and plug in to the array of the "for each loop", instead of "make an array" from the reference) it will not trigger "for each loop". However, when I use the array it goes to "is valid" but then it fails and print "not valid"

[frosty heron]

Use montages....

you loop through an array or 1 reference?

Cooldowns and Timers: GAS allows for the implementation of cooldowns and timers for abilities, effects, or actions. This ensures balanced gameplay and prevents players from spamming powerful abilities.

Multiplayer Support: GAS is designed to work efficiently in multiplayer environments, making it suitable for implementing complex gameplay mechanics in online multiplayer games.

Modularity and Extensibility: GAS is highly modular and extensible, allowing developers to easily add, remove, or modify abilities, effects, and attributes without extensive reworking of existing code.

Data-Driven Design: GAS promotes a data-driven design approach, where gameplay mechanics are defined through data tables and configurations rather than hard-coded logic. This enhances flexibility and iteration during game development.

RPG Systems: GAS is well-suited for implementing RPG systems such as character progression, skill trees, and item effects. This allows for deep customization and progression in role-playing games.

Ability Combo Chains: GAS enables the creation of intricate ability combo chains where executing specific sequences of abilities results in unique and powerful effects, encouraging strategic gameplay.

[haughty iron]

Quick question regarding editor widgets. I have a data table that contains all my card information, I’m running asset tools to loop through and create / update a set of primary data assets, one for each card. This works fine, when data is changed inside the data table I can use my update function to update the correct data asset and save it. Now I created all my creature cards using a similar technique. However, I want to apply the data asset to the blueprint actor it’s related to example DA_card should be assigned as a variable inside BP_Card. There doesn’t seem to be a way to run through a loop of the BP card blueprint and set the variable inside to the Data asset. I could do this manually, I have 340 cards 😭 I’m just thinking is there a way to actually assign and then save it inside the blueprints using editor widgets ?

[dawn gazelle]

This doesn't sound right. Could you not just assign the data asset to BP_Card as a variable, and then read the value from the data asset in BP_Card when necessary?

[hardy magnet]

Working on the concept of a "main menu" for what is genuinely my first ever attempt at using unreal (trying to create a turn-based game). Long story short, I'm followed a quick tutorial and now I'm committing the cardinal sin of trying to integrate another tutorial I found into my project. When running without the main menu flow, game allows me to click on pieces, move them around, and it ends the turn when I have set it to.

When running with the main menu, the game appears to assign the "NetMode: Server" screen to the "Card_Table" level, but places the "Client 1" screen on the "Minimal_default" level. I think this means I am incorrectly playing the game, or have set up something incorrectly either in a blueprint or with setting the proper gamemodes. Some screenshots of my blueprints as well as the game world not loading properly when I click on "Start Game" in my menu.

[haughty iron]

That’s what I plan on doing however, the creature blueprints are children of the base creature type, each creature needs the variable inside it. I can open each blueprint manually and set the variable of the data asset to the correct creature but I was wondering if I could use the asset tools to do this using an editor widget like I have with the data assets

[dawn gazelle]

You shouldn't need a seperate blueprint for every creature. Your data assets are what could contain the data and even instructions or abilities of the card. You can subclass your primary data assets as well if needed to add more values and common functions.

Then you should only need 1 BP_Card, set it's associated Data Asset, and then you can run functions and read values from the PDA.

[haughty iron]

How would you handle creature specific abilities if there is only one base creature blueprint ? At the moment there is a for each loop inside the parent, it can read the data asset for the attack patterns of a creature. Using a switch on enum it fires off an add actor component for the attack pattern so each creature can have its attack pattern correctly assigned, having it as one blueprint seems a little complex for handling specific abilities within the attacks as they can differentiate between creatures using the same actor component attack style, bit confusing

[dawn gazelle]

If you have varying abilities you probably want them separate from the cards themselves, and then you can assign the abilties to the card.

[haughty iron]

Like these cards, I’d have to create a lot of actor components and assign them in the base blueprint ?

[dawn gazelle]

I'm going to guess there's likely a bit of overlap within the abiltiies of your cards, with maybe just some values changing. It'd be best if you were working in C++ to manage it as you can instance an object that represents what an ability can do and show and hide values for that particular object.

[haughty iron]

I’m meaning to get into c++ after just finishing my uni year, it’ll make life easier, I know c# so hopefully not too hard

This was how I built all the data assets using the create asset tool

[frosty heron]

Your component is set to no collision

[steel star]

i noticed that too and changed to queries only, and still no change in result

[frosty heron]

You trace with vissivility

Vissibility

[steel star]

😄

[frosty heron]

But your component is set to overlap on vissibility channel

Change it to block instead

[steel star]

yea, the other guy pointed that out and i changed

i ran out of ideas

[frosty heron]

Do a line trace to see if u actually hit the comp

[steel star]

well, i don't, that is the issue

if my cursor (where im tracing) is over the static mesh (which i have collision also for) it hits

but i have a 64x64 or w/e it is widget around it too, mounted to a center socket

which is like a reticule around the ship

[frosty heron]

My suggestion would be to do a line trace manually with draw debug. Then ensuring you are able to hit the component with a print string. If that's not happening then keep checking your collision settings imo.

[steel star]

hm. ever try to debug a trace call? like.. put a conditional breakpoint somehow for the specific widget..

well, wrong channel for that

[frosty heron]

I just print string on hit component

[lunar sleet]

I noticed the DataAsset docs now tell you to implement it in cpp and derive from it in bp. Is there a specific advantage to this as opposed to just creating those vars directly in a DataAsset bp?

[hushed orchid]

hello, i am trying to build Unreal source 5.3 with VS 2022 and having Windows 11. But for some reason, as soon as the build starts , maybe after 11 to 15 / 6000 , sudden bsod happens.
2. i tried to install older versions of nvidia driver, updated the latest updates from windows update, updated the VS too but still same result.
3. I tried seeing the logs in event viewer but i could find only repeated ones which i am not sure if its related to my crash with building UE source.
Any ideas on how to solve this ? thanks for answers

[lunar sleet]

try #engine-source instead

[hushed orchid]

thank you

[maiden wadi]

Nothing specific for normal data assets. PrimaryDataAssets have the extra AssetType stuff you can use. Can't see why they'd say that for normal properties though. But it is normal to keep your DA classes in C++ unless you're a BP only person.

[lunar sleet]

I don't mind putting them in cpp, was just curious if that is any different than creating a bp class derived from PrimaryDataAsset

[dawn gazelle]

There's some really fun stuff you can do with DataAssets in C++ that you just can't in BP, like showing and hiding fields under certain conditions or having fields limited to certain values (like gameplay tags only allowing tags from a certain hierarchy to be selected), or the best that I've seen, is having arrays that allow you to instance objects for the asset which then also allows you to give additional definitions of properties or behaviors for those assets.

[lunar sleet]

Interesting, thanks!

[quartz flare]

Can anybody tell me what the animation blueprint node that blends in your active montage is called in the pop-up? I have to keep copying and pasting it because I can't find it in the menu to create one from scratch.
First one usually says like "Slot UpperBody Group DefaultGroup"

[frosty heron]

While it can be used for blending, it is just a slot. You can just right click and select Add Slot Default Slot

you can then select the slot to change the slot to existing slots you declared in Anim Slot

[quartz flare]

Hmm when I right click in an ABP and type "add slot" there are no results, and looking through all the "slot" results I don't see a match

[frosty heron]

just type slot

[frosty heron]

Read above, those upper body slot don't magically exist. You have to define them in your anim slots

Upper body is just a name that is declared, you can make one with any name.

[quartz flare]

I have 7 slots defined

[frosty heron]

Screen shoot

[quartz flare]

Upper, Lower, Full, etc.

[frosty heron]

What is your actual issue? You can't find your slot? Or are you looking for blend per bone node?

[frosty heron]

U already have the slot

[quartz flare]

When I need one I go to an old ABP and copy it b/c I can't find how to add one from the pop-up lol

yeah but how do you reference it in the blueprint?

[frosty heron]

Just type slot

If u want to pull the node above

[quartz flare]

oh for f's sake

I typed slot and scanned that list like 100 times

[frosty heron]

I said that like 5 mins ago tho

[quartz flare]

yeah I have no clue why I did not see it

lol

I have been staring at this list for like 20 minutes trying to find it

It work well, my texture shows normals variation without issue. (img3)

Thing is, I only want that cam to see those cube, so I set them to Only Owner See = True and at that point, nothing show. (img 4 & 5)

Am I misssing something?

[dim siren]

I doubt this will do anything, but in your Ship_Base Components window, try dragging the Mesh on top of the DefaultSceneRoot so the mesh becomes the root component.

Had some problems with overlap events and traces not returning any values, but doing that for one of my actors fixed it. Not sure if it applies here, but worth a shot if you didn't fix it yet.

[tough creek]

I feel like I'm missing something simple here- I want to make a function that I can then re-use in several different other blueprints. I've made a blueprint function library with the function but the function doesn't appear when I search for it in another blueprint. How do I get my function library to appear in other blueprints?

[versed oasis]

I'm actually curious, how would someone achieve the Metal Gear Rising Blade mode effect inside of blueprints/unreal in general? Is it doable even?

[dim siren]

What does the Metal Gear Rising "Blade mode effect" do? 😛

[versed oasis]

https://youtu.be/E6pWNFCGBjY?si=jXd4Z1fgTWg2sV09

Pretty much this

It gives you a target which gets rotated using mouse while slowing time almost to a pause.
(Until here it should be easy to achieve)

However it then gives you this patterned plane (?) and once you slash, the mesh in front of you gets split in parts based on how/where you are aiming being able to slash it to even tiny pieces

[tough creek]

I only have the default filter by label function, not my custom one.

[versed oasis]

I'm assuming it replaced the mesh with 2 new meshes and then slashes those to even smaller pieces. Does unreal have a feature allowing you to slash meshes? In new ones?

[dim siren]

I see. It should be possible, but you're looking for a way to slice meshes specifically? It's easier if you break it down into manageable chunks, no pun intended.

There are some tutorials for mesh slicing using Blueprints.

[versed oasis]

I'm assuming it would be better in c++ but my coding experience stopped when classes were introduced in it back in my university years, and I would rather avoid it unless necessary as I feel like learning coding Is impossible for me since I have quite the bad relationship with maths

[versed oasis]

Definitely gonna look that up then

[dark drum]

They're nav link proxies. They tell the AI (when using the nav mesh) that they can go from A to B (in a straight line) even if it goes off the nav mesh.

ah ok

would i need to make that for each ledge?

[swift kiln]

Hey Im bumping this here because I think this is more of a blueprint question. So basically I created low poly water material that has 2 parameters - height and speed. Now I have a blueprint in which I basically tried to do water boiling logic (the parameters will increase smoothly). I tried creating dynamic material instance in the construction script, but that doesnt seem to help. Basically, the material is doing weird things where it just sets the parameters in instance to whatever it wants, but when I check it in editor (with that print string), it looks fine. Any suggestions?

[lofty rapids]

and i'm guessing you set the material somewhere ?

do the the initial values work if you change them to whatever you want ?

[swift kiln]

Yes they do

[lofty rapids]

oh i c you have the water mesh plugged in so it should go to that

[swift kiln]

Should I change the source material to the material I want or just set it in mesh directly?

I tried whatever it just doesnt work the way it should

the values are printing just fine, but the material doesnt behave how it should

[lofty rapids]

i think you should put the instance of the material in source ?

i have only used it a couple times but i think thats what you need for one thing

[swift kiln]

Tried that, still wont work

[lofty rapids]

i have only created, then set the material

[swift kiln]

And it works fine?

[lofty rapids]

i have not tried a water effect, but i used it to change a parameter

and i had no issues

i just created, then set the material on the mesh to the instanced one

[swift kiln]

Can I check the parameters in material instance in runetime?

Because values that Im checking look fine

so Im guessing its just have to be something with the material

[granite elk]

Has anyone had this error before and might know whats causing it? im not making any lengths checks

My game works as intended so im unsure where this is coming from.

[lofty rapids]

i'm guessing the length is less than 10 ?

you cut off the spot that shows the length

[granite elk]

sorry let me reproduce it

[lofty rapids]

well according to the error, if the length is less than 10 then your accessing out of bounds of the array

[granite elk]

yeah im just unsure why that is. if i remove an element from the array does this move the higher array indexes down?

[lofty rapids]

are you removing while iterating ?

and also are you using the index from a loop ? or i'm guessing it's just a variable ?

[faint pasture]

show your code

[lofty rapids]

but you shouldn't remove while looping over an array

[faint pasture]

or at least don't remove while iterating forwards, do it backwards so the removal doesn't make you skip elements

[granite elk]

thank you both im pretty sure that's the mistake I made

[dreamy mountain]

Hey, guys!
I have a blueprint actor that I place in level. I change the values on exposed variables and stuff on the components (Transforms, spline points etc.) on the placed actor in level. I want to apply all these changes to the blueprint class. How would I do this?

[thin panther]

you don't

you can't apply a change in an instance back to the default object.

[indigo stratus]

Hmm.. okay. thanks!

[faint pasture]

You can do it the other way around

place in level, then modify defaults and see the results

[indigo stratus]

That's the way I do it right now. But said blueprint has 10 very long splines in it, that I use for a simple race. It's very tedious to work in the blueprint and watching the result in the level.

[thin panther]

You'd probably want those to be customised on a per instance basis anyway

[indigo stratus]

Not really. I have the 10 splines and just move a target on the spline. I want to spawn them within the blueprint.
