blueprint

[thin panther]

ah mb then didnt see min

read it too quick

in that case then yeah thats good, unless unreal's for loop has built in overflow handling

[tight pollen]

then what should it look like? some screenshot?

I'm curious about the second option

[thin panther]

like that i imagine

[slow pewter]

so anyone know what eaxctly is happening in Remove Index BP Node?

[maiden wadi]

Don't forget to -1 the NumOfItems

[thin panther]

ah yeah

there we go

[tight pollen]

thanks 😉

I'm only worried about performance in 40-100 positions

can it somehow be replaced so that it does not have a bad effect on performance?

[maiden wadi]

Unless this is running on a legitimate calculator, I wouldn't bother caring.

Even then I'm not sure I'd care. 😄

[thin panther]

generally you never have to worry about that

you could loop through it every frame and it still probably wouldnt matter that much

be a bit pointless

but theres a lot worse you could do

[maiden wadi]

Like sweeping character movement calculations. 😄

[gentle urchin]

Depends alot on whats done in the loop

[thin panther]

see this

[thin panther]

true, but just looping through an array is pretty light

[gentle urchin]

There is seldom use for just looping through it

😄

[thin panther]

i mean if thats followed up with like 12 get actors of class, and spawn 12mil poly meshes then it might get a tad problematic

i might put away the calculator for that one

unless its like a ti-84, it seems they can do anything

[tight pollen]

this loop i use only for UI

for Images

[gentle urchin]

reading textures then

no trouble

[maiden wadi]

The amount of loop filtering and checking, and such that goes into UI design would make some people cringe.

[thin panther]

UI design makes me cringe anyway tbf

[maiden wadi]

It is certainly a different way of doing things for sure.

[tight pollen]

so i don't have to worry about that? 😄

[maiden wadi]

Add about fivefour zeros before you have to consider worrying about it. -edit: Blueprint and all.

[gentle urchin]

Not untill it becomes a problem 😄

[tight pollen]

XD

ok, thanks

[gentle urchin]

I'm doing 1000 loop iterations per frame, no trouble x)

not even a dent!

[wide nimbus]

Anyone know why I can't assign Object references within a DataTable? It just skips the field in the row editor

[maiden wadi]

First curiosity is the name. Will test.

[wide nimbus]

Maybe it's worried about referencing itself? But I can still set the data manually in the CSV or something

[high ocean]

What are [EventActorBeginCursorOver] & all other click interface functions based on? I mean, a component could have it based on collision+raytraces (I'm guessing) - this one however requires the mouse cursor to be in an area roughly somewhere around the blueprint's scene root. I would need to use it since working around the components would be a pain, but idk how to make it's "hitbox" bigger/tweak it since idk what it's based on. What does the engine mean by "actor"? It's bounding box? Instructions unclear 😅

[maiden wadi]

Oh, wait, no.

You can't assign Object references as static data.

What are you trying to put there generally?

[wide nimbus]

Depends on the Itemslot, it'll be a Material OR a Static Mesh reference

or Skel Mesh potentially

[odd ember]

yes

[maiden wadi]

Hmm. I'd assume that it's an issue with assuming that uobjects can reference instances of things instead of static assets. You can change this to a SoftObjectRef though.

[wide nimbus]

lol it was working fine in the struct (I made it a map originally, but wanted to be make it a table so it doesn't have to live in my game instance or something)

[high ocean]

@odd emberThen, why doesn't the bounding box take into account the huge meshes the actor has as components? 😄

[wide nimbus]

perfect, thanks!

[maiden wadi]

Should probably be a soft object ref anyhow. 😄 Best not to hard pointer that stuff in static assets unless you really need to.

[wide nimbus]

You right 😄

[odd ember]

if it's perspective, maybe something is obstructing it?

[high ocean]

@odd emberfair point, i'll check. thanks!

[swift kestrel]

Get class default isn't passing my variable value to my inventory system. In my items they automatically get there info from a datatable and that information is stored into a variable which is accessed in the inventory by the get class default node.

The item detail variable is getting the correct data. I've checked it with print strings on the items and the correct information comes out. But when I access the variable in the inventory system using the class default all the data isn't there. If I manually set the data in the item details now it shows up.

Get class defaults also isn't showing the correct values even in the item class. Even though the info is going into the variable correctly without problems it doesn't show the data inside the class default unless I manually input it

[high ocean]

I'm fkin retarded - it was the fog sheets with collision on 😒 U saved me hours of pointlessly digging stuff online - again. Thanks! @odd ember

[native ice]

hey all, is it possible to create a bp spline with attributes to control how wide a mesh is?

[gentle urchin]

Yeah

[native ice]

i'm creating a pavement/sidewalk and need at times for the pavement part to be wider.

[gentle urchin]

but it can get pretty complex i suppose

if you want it to be just 1 spline atleast

[maiden wadi]

Wut? I'm confused, are you getting your data from a datatable or the item's class defaults?

You cannot edit the CDO in blueprint, and you should not edit the CDO even in C++.

[native ice]

hmm, i have seen you can have multiple splines in a single bp right?

[swift kestrel]

Im using that node to retrieve the item details variable but the updated data isn't showing up

[maiden wadi]

It doesn't get updated. You don't change CDO values except in the editor in the blueprint class.

[native ice]

nvm - i'm going to watch this https://youtu.be/wR0fH6O9jD8 - i think i'll find my answer here

[maiden wadi]

The CDO is a default object that is created and held in memory so that Unreal can copy it for quicker object instantiation. When you edit values at runtime on any instance of this class, you are not actually affecting the CDO at all. It retains any values it had when you start the game up.

[swift kestrel]

Im editing the variable in the constructor thought

[maiden wadi]

Construction script or Constructor?

[swift kestrel]

Construction script

[maiden wadi]

That runs on an instance after instantiation, not the CDO.

[winter garnet]

People, I have the image below describing a Widget Component I have in an Actor. Looks neat.

However, if I get far, this is what I get

What I want is to always have my Start Match \/ to look at the center of my mesh

This is the Widget component config:

I'm not exactly sure how to achieve that. Ideas? 🤔

[dawn gazelle]

It is at the center. It's just a matter of perspective.

[winter garnet]

It is, you are right. However, I'm not sure how to "bypass" this perspective to force the Widget to always feels like it's at the center, no matter what. Because what was shown above looks clunky.

[maiden wadi]

Not actually sure if you can fix that... Then again maybe.

Need a test environment.

[mossy valley]

Posting this again since no one responded.

Hey, so I am trying to tie the FOV of my game to the velocity of my first person character, but for whatever reason the velocity is set to 0 when I crouch, even when I am crouch walking around. This causes the FOV to just jump back down to the base value instantly when you crouch. Any ideas why this might be?

[gritty trout]

Maybe establish a point on the bell mesh and then raycast to the camera and place the widget in the midpoint of the raycast

[dusty elm]

Is there any difference in how you control the character when running vs crouching. Ie maybe if you were using forces to control when walking, but a fixed movement input when crouching?

[mossy valley]

No there’s no difference. I’m just using the base Unreal crouch and uncrouch functions.

[green turtle]

Hi, I'm new, I'm trying to figure out buttons for doors/animations but without using trigger boxes because as it is right now you can open the door from anywhere in the box but I want it so you have to look directly at the button, any thoughts?

[zealous fog]

Look into traces

[green turtle]

Sorry, i only just started coding this year, what are traces?

[gritty trout]

How would I edit my pawn movement speed from the Behavior Tree blueprint?

[odd ember]

that's cheating!!1

[green turtle]

Thank you

[maiden wadi]

I HAVE VICTORY

[winter garnet]

🤔

[maiden wadi]

This is a personal widget component of mine. But if you replace GetOwningComponent->GetOwner with a passed in variable of your actor that has the WidgetComponent, this math would let you point the bottom center of the CanvasPanelChildWidget at whatever you project to the screen.

May need raised a little with some Y subtraction, but it always points that V at the target.

Hmm. Just gonna go archive this into a blueprint function library in C++ now. Neat function to have.

[odd ember]

I read this in the voice of michael scott from the office 😂

[maiden wadi]

Close enough. 😄

[livid fox]

Does anyone know how to find ghost references to an enumerator? All I know that there are two references in a particular blueprint:
1. ExecuteUbergraph_BP_Character_Player
2. K2Node_ComponentBoundEvent_1

For context, I am trying to delete this enumerator

But every attempt to delete the enumerator causes errors because of existing references to it

And when I re-add the file, I can't find the reference at all

Uh, ok, it magically disappeared

😨

Just gotta figure out why my Blueprint Interface is still hanging onto it

Ok so. I figured it out, and this is dumb

I had to force save the file

Or make a random edit to save

[winter garnet]

So, I was experimenting with your solution and one question came up.

[winter garnet]

This is occurring inside the User Widget file, right?

[maiden wadi]

Yes. Everything screenshotted was in the UserWidget's Tick.

[winter garnet]

What I quite wonder tho

Is this a Static Mesh? 🤔

Or an Actor?

The type of it I mean

[maiden wadi]

Actually that was an Actor, yeah. 😄 Not sure why I named it that. In that case it was the actor holding the WidgetComponent that the Widget is in.

[echo salmon]

How i can cast to a custom Actor class ? I cant get actor -> cast to my BP.

[maiden wadi]

Why can't you?

[winter garnet]

That's a neat function, indeed! Honestly, I've always had this problem I raised and never got the balls to overcome the issue myself. So I'd buy it if it was a Marketplace plugin 😛

Anyways

[echo salmon]

which node is it ? I have to get actor and then cast to my custom BP actor ?

[winter garnet]

My Widget is invisible 😦

Not invisible... Like, it goes off screen to somewhere over the rainbow I can't see

And I believe it's exact the same code?

This GetRepresentativeSceneComponent is just part of an interface that asks the Actor to pass which SceneComponent represents the mesh I want the arrow to point to

And the Wrapper is the equivalent to your CanvasPanelChildWidget

[trim matrix]

Hi Everyone,

I've been following this guide to implement a way of sending an URL via WebRTC/Pixelstreaming into unreal:
https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/PixelStreaming/CustomPlayer/

See the attached pictures showing my work against the example in the tutorial. As far as I see, the code checks out. But I'm not setting the affect. Does anyone know of a good way to debug this? Increase verbosity? writing to the screen/log file? Something, so I know what's going on unreal side 🙂

The URL is inject like this

[lime yoke]

I've got a question about the sequence node. Is this the same? (ignore the fact that in the first picture there extra nodes connected. This is just an example).

[gentle urchin]

Yes and no ?

[fiery ridge]

I'm looking for a node that returns true/false based on a list of strings. (eg if any of the string is found)

[maiden wadi]

If your Hierarchy is correct as in a Canvas and then your Wrapper in it, I'm unsure. this all looks correct, unless this tagged function here is causing trouble. Like not returning a valid scene component, or the world refs acting weird.

[gentle urchin]

Sequence will execute them in order, but not latently... if something hold up on any of them, the rest is finished immediately, so to say

[lime yoke]

That's what I wanted to confirm. Thank you very much!

[fiery ridge]

I know there is such a node just can't find it

[gentle urchin]

Given this scenario

the outcome is identical

but as soon as you add some latent stuff to it,

they will differ

In the first example, 2 bools will be set, then delay, then 2 next bools will be set

using the sequencer however , will set all 4 bools instantly,

and whatever is connected after the delay will be executed after the delay

the "Sequence" is asap firing off the next event

[winter garnet]

@maiden wadi This is the structure I have. Pretty close to yours, except that the Wrapper is not a VerticalBox but a SizeBox.

But I bet this wouldn't be the culprit.

[maiden wadi]

This should be fine. It's the CanvasSlot that matters.

I'd double check that other function first.

[trim matrix]

BTW if anyone can help me so this blueprint issue, there's a bounty

[winter garnet]

Yea I'm doing that right now... Let's see...

So, after some investigation @maiden wadi

This is where my Print String is

It seems correct lol

I need to dive deeper..

But your idea on how to "address" this problem is just shiny. 😄

[maiden wadi]

That's odd. I don't see anything wrong with your stuff.

Can you print before the SetPosition what is coming out of the minus node?

[robust kelp]

keeps saying manquin needs a skel mesh preview it does

trying to mixamo transfer

[main lake]

Is there a shortcut to focus on a node if your Zoom level is too low ?

[robust kelp]

f

[main lake]

doesn't work on nodes for me

[rotund fern]

in event graph, you can double click it

if it's a specific event you want to focus

unless i'm misunderstanding

[main lake]

No I want a shortcut to focus on all types of nodes

like for instance I have a branch I need a shortcut to focus it because my middle mouse button doesn't work properly (when scrolling)

so like the F button in the 3D Sceene to focus on objects

[dapper grail]

Hi all! Duplicating question my question from #cpp because don't know were exactly is my mistake xD
I have weapon c++ class with declaration of overlap events (it seems correctly because same code working fine with another actor) but overlaps for weapon never called. Where the mistake can be hidden, what BPs should I screen?

[robust kelp]

ok it works

[fiery ridge]

my WorldStatic objects can register overlaps but not hits? yes i've checked simulation generates hit events

[dawn gazelle]

Looks like you have the "Collision Enabled" option set to NoCollision. This at least needs to be set to Query only.

[runic urchin]

how would you check to see if a material is applied on a static mesh in an array?

I have this so far and can print out all of the names of the static meshes from the sharedroot but cant figure out how to collect the materials applied from the children components

[maiden wadi]

GetMaterials->Contains(WhateverMaterialYouAreComparing)

From the ArrayElement

[runic urchin]

I've tried that but nothing comes up when pulling from the array element.

[main lake]

Is there a shortcut to focus on a node if your Zoom level is too low ?

[runic urchin]

I do have Context sensitive turned on

[runic urchin]

ty

[maiden wadi]

Should work. May want to drop into a function if it's a simple bool check or retrieval of a single mesh component for early return.

[unborn compass]

can we ask nooby questions in here?

[maiden wadi]

Nah. They have to be entirely noob. No nooby halfways allowed.

[unborn compass]

lol

aight well this ones pretty bad so i'll see if anyone responds i guess lol

so i'm going to try to phrase this well.... I want to call a function from my gamestate to end a players turn, but I want to call it from a widget on the clientside player controller. It doesn't appear to do anything even though the player controller intermediary function is set to "multicast" or "runs on server"

any thoughts?

[dawn gazelle]

You cannot RPC to gamestate directly. Your widget can trigger an RPC on the player controller, and once running on server do the stuff on gamestate.

[unborn compass]

i'm going to research RPC and try again, thanks

[dawn gazelle]

So have a "Run On Server" event set on the player controller that will call whatever you want to do on the server in the gamestate.
Then your process would be:
Push Widget Button > Call that newly created Run On Server event on Player Controller > It'll end up doing what you want on Gamestate

[unborn compass]

thats how i have it laid out now

let me grab screenshots

lmk if you spot anything, i'm unsure what the gamestate function should be (multicast orrun on server)

[dawn gazelle]

Should be nothing. You're already running on server from this point.

[unborn compass]

lol

i think i might have spotted it.... i didn't connect that player index on the second image

lmao

i guess i'll use this as an opportunity to ask why this code works when i run "play as client" but not "listen server"

its kind of a mess though lol

[faint pasture]

@unborn compass You're always telling it to end player 0s turn. That is incorrect. If you have more than one player you'll have different indices. You should just pass over Self from PlayerController to EndTurn function in GameMode or GameState and let it figure out the index if needed.

Every player is Player0 LOCALLY but they have a different index on the server. Don't use indices until you're serverside.

[dusty elm]

Im having a problem with the new water feature, and I hope maybe you guys can help. I am sending out a trace of the projectile arc, which is fine, but what I really want to do is determine the firing angle from the end location, maybe using physics. What I am trying to do right now is to use the camera and a line trace (the red) to find out where in the water they are pointing the camera. The problem is that the line trace does not seem to interact with the water, it just goes right through. It works with the projectile trace though, just not the line trace by channel. Idk what to do. Also if you have any tips for this kind of mortar thing let me know thanks!

[unborn compass]

thanks for the response, this image is from the gamestate

and the 0 from the == is just to seperate when one player ends vs the other

essentially "is this player 1 or 0 ending turn, true is player 0 and false is player 1

Also the player controllers know their indices as i've had it sent to them earlier in the program

like i said, this works completely as intended when using play as client, but on listenserver something doesn't get sent at the beginning

[jovial elm]

I'm having trouble with checking for a gameplay tag on an object. Im using on actor begin overlap event and then checking of the overlapping actor has a certain tag and displaying a message if it does and message if it doesn't. I've assigned a gameplay tag to the actor and even checked if it's assigned by displaying the tag as a print message when the game starts up.

When the actor overlaps, the result always returns as false and I'm not sure what's going wrong.

[unborn compass]

i saw in a youtube video that you can see when the functions fire on the editor, like with those "bubbles" moving down the line of functions

anyone know how to do that?

[mental trellis]

That's just what happens in PIE. I believe when it's active, you can select the instance you want at the top of the bp editor

[unborn compass]

yeah it doesn't show the same red bubbly line for me when things are getting called

unless maybe it only does that for things that are happening constantly

[mental trellis]

Have you selected the correct instance

?

[faint badge]

The function you're using assumes your actor implements the interface: IGameplayTagAssetInterface which is not implementable in Blueprints. You'd need to make a base C++ class if you want to use that and implement the interface on it.

If you want to do it purely in Blueprints you need to either try to cast Other Actor to your class and then get the tag variable directly to compare or you could make your own Blueprint Interface and have that return your tag or a tag container

[trim matrix]

Hi all, so when the length of an array is counted does it start counting at 0 or from 1 ??

I am having an issue where my array thay have item 0,1,2 when I go through and I do a check if less then or equal to item index in array against length of array it not working

I either have it not do last item or it adds an additional item to end

[mental trellis]

An array of length 5 has indices of 0, 1, 2, 3 and 4

[pine trellis]

can anyone else see the pictures people uploaded to the unreal engine forums? everytime I click on a blueprint it says page not found https://forums.unrealengine.com/t/line-trace-hit-normal-when-tracing-on-edge/388491/2

then I cant see the blueprints people use, it use to show the pictures

[trim matrix]

So when I check if equal or less than it would be wise to minus one from my array length so I get the right length that matched the 0, 1, 2 etc ??

Or would I start my index number on 1 by default

[mental trellis]

Or just use less than instead of equal or less than

[odd ember]

there's also LastIndex which is length - 1

[trim matrix]

So instead of length I can just do last index and check that against the index number

I would prefer the length to match with the 0123 etc then length starting at 1234 etc

[trim matrix]

Would using this allow me to do that

[mental trellis]

So you want length 0 to be 1 item at index 0?

[trim matrix]

What would you advice

Would it be better to start my index on 1 so it matched with what the length would return

[mental trellis]

It would be best to use arrays how they are meant to be used :/

[trim matrix]

Like

[mental trellis]

If you want to check if your index is valid: >= 0 and < length

[trim matrix]

So basically I want to check when I have gone through the total number of array items

So I do something add one to the index and grab next item then do a check and repeat

Until the item grabbed is greater then length of the array when it will do something else

[faint badge]

Is there a reason you're not doing a For Each loop? That will go through each thing in your array and then has an execution pin for when it's gone through everything

[sharp rapids]

If I save a static mesh variable in a Save Game Object, will it save all the mesh data (vertices, tris, etc.) or will it save a reference to that asset on the disk?

[quasi relic]

Is there a way to get only a location in the red area and not in the orange/yellow area? To get a location in the yellow area and not the red area?

[jovial elm]

If I wanted to stick to blueprints, wouldn't there be no difference really if I were to use regular tags instead of gameplay tags? My understanding is I cast to Other Actor and then retrieve the tag info from it, convert it to a variable I can use locally within the current actor and then use that to check? I feel like this defeats the whole purpose of gameplay tags as a whole. Please correct me if I'm wrong

[sharp rapids]

Well, if those areas are circles, you can check for distance from the center and decide if the position is in the required area or not

[quasi relic]

Ok I'll try that out, thank you

[gilded elbow]

Hey there. I'm a bit new to sockets. Any reason why this is spawning and immediately falling to the ground? Thanks 🙂

[sharp rapids]

Maybe it has physics enabled on it?

[runic urchin]

I have bp exposed to cinematics but the keyframes I have set in sequencer are not rendering in movie render queue, anyone see this behavior before?

or know how to fix

[gilded elbow]

@sharp rapids aha! That was it. Thanks!!

[quasi relic]

I want to have a deployable bipod system in my game. Players will be able to deploy their bipod on surfaces of different heights. Should I handle this by using different animations of the character's knees at different heights(seems like a lot of anims) or can I use IK to bend the knees to a degree depending on the height of the surface?

[tight schooner]

Sounds like an #animation question. Arma III had a stance system like that. If I recall correctly, they had multiple leg positions for different ranges of height, such as dropping to one knee, full butt-on-ground sitting and then finally prone. So it was a blend of different animations and IK; it's a milsim so it's simulating what a person would probably do.

[tawdry surge]

Ik

Power ik plug in is free and pretty good

[cursive path]

I have question about node does save game exist no need to cast or anything to use this it will follow the default path on game contet right even if level persistent is different right?

[bleak swift]

Does anyone know why the widget doesn't remove from parent whenever I press escape with the menu already open

[gentle urchin]

Replace destroy widget with remove from parent,

Also dont create a new widget if the reference is valid, jjst add to viewport

[bleak swift]

I mean I legit just have remove from parent in that function

[gentle urchin]

And swap your bool with the integrated is in viewport check

[gentle urchin]

Couldnt possibly know that 😅

[sharp rapids]

How do I access a BP in a Level instance that was loaded using Load Level Instance?

[bleak swift]

Don't see that

[sharp rapids]

I tried using Interface on the level blueprint, but it simply does not work, There is no way to access the level blueprint on a spawned in Level Instance

[gentle urchin]

What are you trying to do?

[sharp rapids]

I'm trying to divide the map into chunks and then load them in as needed, (like Minecraft)
I have a base level that I'm using as a chunk. I create instances of it at runtime. That base level contains one actor that is the placeholder of the chunk mesh. I want to access this actor after the level instance has been spawned in.

I tried using an interface on the chunk level bp that return the chunk actor. But calling that interface on the loaded level instance does not work. Load level instance returns a 'Level Streaming Dynamic' reference, which, after some testing, does not implement the said interface.

It seems you need the 'Level Blueprint'. But there does not seem to be a way to get a ref to it from the Level Instance object 🙁

[bleak swift]

@gentle urchin I did everything you told me and it still no work ඞ

I am the NeonContext person btw

[gentle urchin]

Would it not be easier to just spawn the actor itself?

[gentle urchin]

Guess ypu gotta show more code then. Both the destroy widget funcrion, and event construct in the widget

[sharp rapids]

Yes. But I wanted to do it this way. for the added benefit of unloading the chunks (and everything in them)

[gentle urchin]

You would still do that, by destroying the chunkmanager(which destroys everything in the chunk)

[gentle urchin]

Set imput mode ui only is your issue

[sharp rapids]

Streaming levels have instant Garbage Collection, that's why I thought about doing it this way

[gentle urchin]

If you really wanted to, you could trigger it manually. Altho i'd rather try and reuse the chunks, but that may not be possible

[sharp rapids]

I might switch to a single level if this does not work out
But my question still stands, is there no way to access something in a sublevel?

[gentle urchin]

There is, but you need some methodto reference it. Be collision, trace etc.

The easy way is often just a simple manager

Which you let the actors register themself to on spawn

[sharp rapids]

The Chunk is a single mesh BP with data such as Tiles, what occupies each tile, etc.
Every chunk also registers the items that were dropped by the player when the player was in that chunk
When the player is far enough, The chunk saves all the data and unloads itself
When simply destroying, The actors get destroyed, but they stay in memory (which pile up after a while and cause one big hitch in the gamplay)
When level streaming, the actors get emptied from memory at that instant

[gentle urchin]

If nothing is referencing it, it gets gced on the next gc trip (usual worst case would be 10 minutes)

Minecraft monitors this and unloads by what appears like an interval and if memory exceeds designated memory

[sharp rapids]

The gc used by level streaming and regular gc are the same ones, right?

[gentle urchin]

Anything else would be double work^^

Ans as mentioned, you can trigger it manually if desired

Altho i wouldnt worry much untill you know the memory footprint of your chunk

[bleak swift]

Make's sense thanks

[bleak swift]

Seem's to be working now but the widget still won't remove

[sharp rapids]

Yeah, I was thinking about that.
But idk why, Level streaming just seems more performant to me than destroying and gc-ing manually
(I haven't tested it though)

[gentle urchin]

Check what code is running. Do some print strings

[gentle urchin]

Premature optimization. I love doing it, but its often a curse :)

Fixing theoretical problems etc

What if ... And if... and then this...

[sharp rapids]

I feel attacked, lol 😅

But yeah, I do that a lot

[gentle urchin]

Not my intent😅

[sharp rapids]

Oh no, I was joking

Wasn't aimed at you

[gentle urchin]

I was just assuring 😂

Anyhow

Id have a high level chunk manager, which all chunks obey,

And a low level one which internally handles the actual chunk

[bleak swift]

It plays all the code

[gentle urchin]

It can't, unless its working :p

Also

Ur not setting the variable

"Pause Menu"

[bleak swift]

What?

[gentle urchin]

You're just creating the widget

[bleak swift]

Pause Menu is just a ref to the widget

[gentle urchin]

Not setting the pause menu ref

[gentle urchin]

You could wrap the widget creation/getter in a function

[sharp rapids]

I do have both of them. The High level Chunk Manager tracks the current player location and decides which chunks should be loaded and unloaded. And then there's a single Chunk BP, that contains all the data about that chunk.
I was split between choosing whether to use Level Instances for individual chunks or just spawning them in the persistent level

I'm gonna go with the second option for now. Will optimize later if required 🙂

[gentle urchin]

Sweet !gl

[bleak swift]

Why would that matter?

[gentle urchin]

Easier maintainability usually

Especially true for branches and stuff like that really

[bleak swift]

I just need it working

[unborn compass]

has anyone ever heard of a for each loop just skipping to completed? The array i'm using is not empty and the for each loop works when its called the first time, but after that as i'm stepping with the debugger it just goes right to completed without doing the loop body

i'm completely bewildered

[gentle urchin]

So save your created widget to your variable, and it will work

[gentle urchin]

Sounds like its empty the second time around

[unborn compass]

there isn't anything that modifies the array after it is set

its an array of player controllers on the game state and the for each loop only changes variables within the player controllers

[gentle urchin]

Guess id ask you to show code then

Theres little reason to suspect it being an issue with the array iterator

[gentle urchin]

Print length of array before stepping into the array

[unborn compass]

i'll try that

yeah so its showing as the array being empty.... i have no idea why though

that "firstplayerturn" is only called once from the gamemode

[gentle urchin]

Getallactorsofclass is not considered good practice either

[unborn compass]

its only on setup and called once so its should be fine

[gentle urchin]

Its called twice already

Ohh nvm

Didnt see

The second event

[unborn compass]

this is all of the code in my gamestate

i just dont get why the array would empty

[gentle urchin]

It seems the array is only set on server tho

Not replicated

So clients wont have access to it

[unborn compass]

its gamestate so it should only run on the server

right?

[gentle urchin]

I believe thats gamemode

Gamestate is replicated iirc

This is more #multiplayer tho

[unborn compass]

gotcha

[gentle urchin]

Saved/stored it now? Did it work?

[main lake]

Is it possible to disable Overlap Event on a Box Collision for a moment to enable it later again ?

[gentle urchin]

you can disable collision

and you can alter its response on channels

[main lake]

I'm already disabling collision but it keeps generating the overlap event somehow

oh wait

[violet wagon]

SetGenerateOverlapEvents could be what your looking for

[gentle urchin]

in this setup, "Pause Menu" will be forever empty (nullptr) because we're not setting it to any instance

while if you set the variable like this ; it will work

However I would suggest setting it up something like this instead

[main lake]

I disabled the collision on the actor containing the box collision because using the box collision it has an event called "Set Collision Enabled" and with NoCollision preset it does work like intended, but the other parameter to enable is Query only or Physics Only or Both and I think it doesn't work properly with the player

[main lake]

I just tried that and it still can generate Overlaps somehow

at least on the client

[gentle urchin]

Or even like this

[gentle urchin]

cant you just filter the event anyway?

If its not ment to react to overlap, simply blocking it would suffice ?

[gentle urchin]

Read above for example^

[main lake]

and printing my player state containing booleans where if player overlaps one of the trigger it puts to true a certain boolean (so each trigger has it's own boolean) and those triggers need to be enabled only at certain time (24 hours system), and using the Generate Overlap Events node it keeps printing true, so I don't know if printing the player state is client sided or server sided or both

[main lake]

how ?

[gentle urchin]

Simply check if currenttime < endtime and > starttime ?

On overlap -> branch (CurrentTime < EndTime AND Currenttime> Starttime) ->

Something along those lines ?

[main lake]

I wanted an easier solution

a question I have what the box collision is at on the collision by default between all of theses states ?

[gentle urchin]

Really not seeing how its easier how you've done it but oh well 😅

all the time its not working 😛

i think query is from traces and such ? while physics is .. well physics collision

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

[sharp rapids]

That is usually set by you on the box component

In the 'Collision' settings

[main lake]

Oh yeah thank you, it's Query Only by default

[bleak swift]

Anyone know how I could replicate this? So that the flipbook is set on server so other's can see it

[gentle urchin]

#multiplayer

[main lake]

I need to know if the player state has 2 versions 1 client and 1 server ?

[gentle urchin]

yes

[main lake]

how to get the server version ?

[gentle urchin]

by doing it on the server

Likee, if the event is executed on the server, it will get its local version (Server version)
while if the event is executed on a client, it will get its local version (client version)

[main lake]

so I messed up somewhere then

[gentle urchin]

The potential complexity of MP games is mind numbing... 😛

[main lake]

But like It prints the overlap on client and server on the first one at the right time, and the others only on client so all of that is good, but printing the booleans it keeps telling me those are true when I overlap triggers that aren't supposed to be active (even if it's not printing the overlap on server when I overlap them)

[gentle urchin]

Server should do all these checks

[main lake]

Is it possible to always have the player state of the client be synced with the server one ?

those checks are done on the server

[gentle urchin]

Doesnt sound like it

and are you really sure

this is easier ? 😄

[main lake]

this print is in the BP_Character printing the boolean of the player state, so it's on the server so it prints the server sided player state

That's the Playerstate with the custom event "ValidateTask" being server side too

the only thing not being server sided is the "Begin Overlap" event of the Box but I don't know if you can make it server sided

[fast escarp]

Is this a bug?

[main lake]

maybe using the HasAuthority node ?

[fast escarp]

or just strange semantics?

[gentle urchin]

c++ interface?

Oh

damn 😄

[fast escarp]

yeah it's just uhh

weird

[main lake]

It's fixed with the HasAuthorityNode

(first time using that node)

[gentle urchin]

that'll ensure it only runs on server

[main lake]

yup thank you

[trim matrix]

Is there a way to hide unconnected pins from all nodes across all blueprints? it's messing up my search results

[gentle urchin]

sounds like a very unique scenario, so i'd bet no is the answer

[obtuse herald]

At the top bar in BP Editor there should be a button called 'Hide unrelated'

[gentle urchin]

does that filter them out of search tho?

[wicked osprey]

Guys, how can I implement inventory logic with items that have custom variables (weapon ammo, sword strength, etc.) How would I best implement methods like 1) Equipment (as I understand it, we must first understand what type of item we take in our hand, based on this, get custom variables looking for the object we need and assign them when spanning) 2) Reset item 3) Pick up (as I understand it, we need to understand what item we should pick up, and based on this, take its custom data, create the desired object based on this and add it to the inventory)
I had a way to implement all this logic through Enum, based on the type of the item, already perform some actions, but wouldn't such code turn out to be too cumbersome? You will have to prescribe your own logic for each item and action. Or is this the only way to implement such logic?

[gentle urchin]

Enum for type, Map for attributes (Ammo, strength, damage value, whatever)

Single player ?

[trim matrix]

hey guys i have little problem with object reference does anyone know how to fix ?

what do I use to get same result?

[gentle urchin]

This is what you're after

the function header tells you its target

[trim matrix]

oh im so silly... thank you I fixed

[fair zealot]

for that first one i guess just drag it out and look for 'get player controller'

[restive oracle]

Hi guys, I'm working on putting in an export movie cinematic sequence at runtime function. So far I can easily output a sequence of images but I am trying to use the AvidDNx encoder plugin to output a video but when I do it outputs a video per frame (e.g. 600 frames = 600 videos rather than 1 video that is 600 frames long).

Does anyone know how to get around this?

[sharp rapids]

What if Ammo is an int, while Strength is a float?
Can a single Map store them?

[gentle urchin]

then you've created a problem^^

Strength would typically be an int in my book

if you need some decimal to it (1?) you can always have a 10x on the strength int,

reduced when displayed

so 501 strengt is actually 50,1

[gentle urchin]

But you are correct, a single map cannot store two different data types.

[sharp rapids]

I have a bunch of different variable types. So, I can't store them in a single map.
I have 'Tools' which have 'durability'.
'Clothes' which have Material Instances, 'display name', etc.
'Placable' items which have different conditions for their placement.
Currently, I have to create separate classes for all of them. There's no generic way to store all those variables in a single class

Maintaining all of them is a pain in the ass 😅

[gentle urchin]

There's always a way, but if its worth the effort is another question :p

Material instance path could be looked up from a string and loaded that way 😋

Placeable would have actor class references

But I wouldnt advice this 😂

[sharp rapids]

Yes. But different items have different placement conditions. Some would require there to be a coal tile, others would need a plain tile, etc.

The current approach has a lot of flexibility in that regard, where I can just overwrite a single function and define the conditions there

[gentle urchin]

Yepp, that's how i'd probably do it aswell

even if it means a realtively large struct ..

with persistant durability etc it almost sounds easier to just save them as Actors or Objects and keep them in the level... almost

[sharp rapids]

I am storing them as Actors 😅

[gentle urchin]

Heh

well there we go x)

[trim matrix]

When I have used a loop in the past its just run through. I'm doing this way because player has control of when to move on to next item in array.

[gentle urchin]

It's hard to give good advice without proper context^ Knowing your codes intention helps in this regard

[trim matrix]

So I have text that appears on screen

Instead of having it all there I have a button which set the text to the next text. I am currently each time the bind event is called to update text

I am checking if the text index is less than or equal to the length of the array. So when there's no more entries I simply remove the widget

So far I think my issue is I'm used Less than or equal to so its adding an extra index where there is no entry

I would be better to do less than, as length starts at 1 but index array starts at 0

[hollow gorge]

A question about widgets: Would it be better to remove a widget from parent or to hide visibility for when it's not needed? (i.e.: player wishes to close inventory or map but will probably open it again soon).

[gentle urchin]

Just hide it

Avoids a few pitfalls

[hollow gorge]

Okay, thanks.

[next robin]

Hey, I have this box collider on a door mesh that on begin overlap it creates a widget and adds it to the viewport, on end it removes it from parent. Right now the whole concept works at times it bugs, as if it doesn't read that I left the box at all, the widget stays on screen regardless

Here's a more thorough explanation

Any ideas?

[gentle urchin]

What happens on Interact

show the code

[next robin]

It seems to work as intended but

[gentle urchin]

You're not showing the interaction code

the code that actually opens the door

[next robin]

but the code that opens the door has nothing to do with the widget

[gentle urchin]

Suddenly it does

[next robin]

okay

lemme show you

It's a custom event that plays a flip flop connected to a timeline. The time line sets the value of frame at 0 to 0 and at 1 to 90 so it rotates. That's it

[gentle urchin]

And your collision volume in relation to your pivot?

hm

alright

so you're not flipping around the volume

and you're not altering collision,

which is good

[next robin]

yeah

[gentle urchin]

Is this really all that happens when you interact tho?

[next robin]

well

there is the

[gentle urchin]

"Key input" -> Open door?

[next robin]

FP pressing the key input

[next robin]

this is in the door BP

and in the FP BP there is

[gentle urchin]

right ok

Make the collision volume visible

uncheck "hidden in game"

in the volumes details panel

[next robin]

Yeah yeah

It stays there

[gentle urchin]

heh

i noticed something

[gentle urchin]

Drawback of crossing wires in exec streams!

[next robin]

Since it's not parented to the pivot

[gentle urchin]

You're creating two widgets

[next robin]

[gentle urchin]

which is the issue..

[next robin]

right

so on leave im actually creating a widget to remove?

[gentle urchin]

Exactly

Its good practice to save the widget refs 😛

Or have it exist in the char, and save it there so only one interaction widget is ever needed

If you were to create the widget on beginplay instead

and just alter its visibility on overlap

this would work flawlessly 😄

Alter visibility or add / remove from viewport , up to you ofc

[next robin]

I see

hmm

okay lemme check

hmmm so altering with visibility didn't really work all that well so i instead just did the adding/removing from viewport as follows

[remote glacier]

Hi all, I have four ammo types and the lecturer only uses two. Would this be the correct way of doing this?

[gentle urchin]

Fair enough, removing it should be pretty safe in this setup

[next robin]

It works, works well but uhm having some minor warnings that are just not fun

[gentle urchin]

Its because the event is fired again

[next robin]

[gentle urchin]

just check "is in viewport"

before adding to viewport 🙂

Not sure why it triggers twice, perhaps the overlap is a tad to small

[next robin]

yeah probably

[next robin]

I was doing that, just thought of a follow up

[gentle urchin]

so then your warnings are gone, yes? 😄

[unreal quail]

I'm trying to remove an EditorOnly referenced asset in some BP that had messy assets everywhere but I can't for the life of me find where is the reference, anyone has any tips?

[next robin]

Yup! Works perfectly now. Simply had it set to true or false when adding / removing and checking on each to make sure nothing slips in that shouldn't

ty

[gentle urchin]

what, setting to true or false? 😮

[unreal quail]

the more time passes the more my hate on the previous dev goes up exponentially

[gentle urchin]

This should be all you ever need

[next robin]

made my own variable

[untold mist]

"clean up redirectors" maybe

[unreal quail]

nah it was because of a get node

🤦🏻‍♂️

there was a disconnected Get Sphere with an empty target which had to be connected to a BP_EnemyProjectile

[scarlet pumice]

Is it possible to take an object from the world and convert it to a class type?
Similar to right clicking content browser, create Blueprint and then setting various parameters...?

say I add an actor to the world, derived from AMyActor.
Then I set some EditAnywhere properties on the instance.

There's no way to convert the Instance to a class type / prefab type thing?
I have to manually copy the properties?

Yeah I was just hoping there was a way to convert an Instance to a PRefab using the Unity terminology

it's quite nice for artists to build some of these objects in the world, but annoying to then convert it to a BP for re-use

I just want to make a new BP type from the same class as the instance and copy the EditAnywhere params

what do you mean manually? copy/pasting the properties?

yeah fair enough, thanks for the clarification

[marble echo]

i have a game that uses multiple 'decks' and the player is able to click on them to draw a card from them. However, with multiple decks in the scene, it seems to pull the card from a random deck instead of the one being clicked. Can anyone see anything wrong with this? I think the problem is around here somewhere

[gentle urchin]

Wouldnt a cardpick like this usually involve some sort of trace?

[marble echo]

how would it be able to know which one is picked?

[marble echo]

how do you mean, sorry?

[gentle urchin]

How does the player interact with a cardstack?

Mouse click? VR Controller? Eye direction?

[marble echo]

just a mouse click

[gentle urchin]

Right,

so you already have a trace

which means you dont need get all actors of class at all

[gentle urchin]

the trace will return the actor currently hovered when clicked

[marble echo]

so what would the target be in the bound event?

[gentle urchin]

Also there's a Get Player Character..

Target would be self, if self owns the dispatcher( which it appears to do)

In this case the card stack

[marble echo]

so these are 2 different blueprints

the deck and the card itself

each card is a separate blueprint

[gentle urchin]

Card stack would normally represent all the cards in the stack,

and have some array of their data/classes

On clicked, The Stack would spawn a new card from this array (remove card from the array),

and give that to the player who clicked it

[marble echo]

the array just has the card 'ID', which it compares when drawn

[gentle urchin]

We're back to the comparison huh

[marble echo]

hm idk

maybe this isnt the right way of going about this

[gentle urchin]

Let me toss up an example..

[whole viper]

If you have a pure function with multiple outputs.

Is collapsing it to the a function a good way to cache those outputs so it doesn't run each time you use output?

or is there another way that doesn't involve creating this new funciton

Seems a little silly to create a new function to get around this

[gentle urchin]

Actually it appears the built in events are pretty bad for this setup

Instead of picking up the overlap/click in the actor, i'd do it in the playercontroller , and forward it from there with an interface

[marble echo]

yeah think you're right. might just scrap this and try again with a different approach

[marble echo]

thanks for looking at it

[gentle urchin]

In the playercontroller, using BPI_Interaction (which just has an interact function with instigator reference (Actor))

then in the carddeck all you need to to is implement the interaction event

which tells you who clicked it (so you can send data in return)

[marble echo]

there will only ever be 1 player in this game, but multiple card decks

its just about the game knowing which deck is clicked and acting accordingl

ah i see

[gentle urchin]

Completing the roundtrip with the implemented interface event in the playercontroller

[marble echo]

so this is all happening in the player blueprint?

[gentle urchin]

playercontroller *

Both playercontroller and the CardDeck has this BPI_Interaction interface

[marble echo]

does this mean each card can still be a different blueprint?

[gentle urchin]

Surely

in this example its just an ID , since that's what you said it was

but it could be a card class

[marble echo]

so how does your event dispatcher have an instigator

[gentle urchin]

I made it, in the BPI Interface

[marble echo]

and i cant seem to make input events in the player controller

[gentle urchin]

Its not a dispatcher

its a blueprint interface

[marble echo]

oh i see

never used those before

[gentle urchin]

Ah

they have their uses

you have to add it to both the PlayerController and the CardDeck

[marble echo]

alright, i'll mess around with this. thanks very much for having a look

[gentle urchin]

No worries

[robust kelp]

trying to set a movement speed multiplyer so when a mount is equipeed move speed increases.. started following https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/HowTo/CharacterMovement/

[gentle urchin]

Get player Char -> Get Movement Component -> plugin to MaxWalkSpeed

[robust kelp]

do i need a variable for player char?

[gentle urchin]

didnt realize you were in the char bp

Just the char movement component

[robust kelp]

wow thats all i was missing?

awsome thank you.. just started UE4 again on new adventure so all new to me again

[gentle urchin]

Wouldnt advice hardcoding the speed multiplier like that tho

typically you'd probably want to get that from the vehicle/animal you're currently on

Or simply attatch the pawn to the vehicle/Animal and let the animal do its job 🙂

[robust kelp]

which is why the variable? so the animal/.mount can change the speed multiplyer?

this is all new to me.. and im getting sick of tutorials not explaining so im figureing out oipn my own with little help.. so yeah........... bound to do thjings wrong i guesss

[gentle urchin]

No worries, you'll learn as you go along

[robust kelp]

oh your saying let the mount manage its own movement

[gentle urchin]

Exactly

[robust kelp]

ok what aboiut shift to sprint?

[gentle urchin]

Then its also easier (and cleaner) to implement things like horse sprint, slow walk and whatnot 😛

you'd temporarily either possess the mount , or atleast enable inputs on it

[robust kelp]

okie dokie

would this way work if i wnat to change my shift to sprint variable later? or is there a better practice?

[gentle urchin]

Yes it would

[robust kelp]

like boots equipment speed?

[gentle urchin]

the horse would then implement the sprint event

You could allow player stats influence horse speed, sure

Horse would know about player on the back, and could fetch the current speed multiplier from the player

[robust kelp]

okie dokie

blue lines ok ort should i bring out a new variable node per action?

i really need to find a better way to learn this stuff lmao.. so many fine details no one talks about

[gentle urchin]

Cleans it up quite a bit by just moving this to a function

Not sure why you divide by 100 ^^

[robust kelp]

to get the %

[tiny frost]

anyone know how to do swinging?

[robust kelp]

big difference between max walk speed 800* 150 or 150%(150/100=1.5)

[gentle urchin]

yeah but why 150 in the first place

instead of 1.5

[robust kelp]

because im complex and was my brains way of figuring out

yeah probably right why the extra step

thank you

[gentle urchin]

sprinting would now look like this

Probably using variables aswell instead of hardcoded values 😄

even encapsulating it further could make sense

[robust kelp]

oh to make it more reusable?

or just cleaner?

[gentle urchin]

Less work if you wanted to change it

If you went for the first method

using this directly

and after a while you've suddenly decided to change the sprint speed

you'd have to search all your code for wherever you manipulate this

When its stuffed into "Sprint" , all you need to do is edit it there, in that one singular place

Perhaps the most correct way would be to have it as read only variable instead

so it'd be part of the class defaults instead

[robust kelp]

yeah i wanna be able to change it with gear and skills and potions etc if i want. i like modularabilkity like that being able to change anything in future if i need to.. will look at the custom event thank you makes sense now

gota go get son ready fo rschool thank you @gentle urchin

[slow pewter]

Okay Guys got now Headache i couldnt solve my Array Problem, like, I have an Arraym, i remove Indexes, with Remove index Node, If i have 1234567, i remove 345, ITs like The begin Work, but the Last Indexes are get copied, so I have 1-2-7-7- , When i Remove in that order 543, it works, than 1 -2- 6- 7, anyone could have an Idea, what is this Messed up?

[gentle urchin]

Are you removing while iterating?

[slow pewter]

no

[gentle urchin]

show code 🙂

[slow pewter]

I can but it wont Help that Much, because I just Communicate directly with Savegame Array, Each reference Sets Each Information, and the Index Creation is assigned at Creation Time, like When i Press button , + 1 Widget and +1 Integer [aka Index] is created, So than from the Savegame it loads the Information and gets the Stored Index and Expose it to the Loaded Widgets, So i didnt touch anything about Index , The FUnny part is if i would fake Delete , like just Set them Hidden, it works flawlessly, but when i REMOVE Index, i dont know its like it does something Wrong with the Array Indexes, because i can look into my Savegame all Information are stored Correctly, only what i can See that the Last one have all the Same Index Saved

also that the Remove is super Simple -> https://puu.sh/IKMmD/783724546d.png

[gentle urchin]

there's a tendency of information being left out when people explain what they do insteadof showing what they do

Mostly because they explain what they think they do (or intended to do) and not what they're actually doing

[slow pewter]

I show u the Important Part ones, because its not that much i Only Communicate the msot with SG directly

[gentle urchin]

Well what you showed me doesnt appear to have anything obviously wrong so

[sharp rapids]

What is that cast node? Never seen before

[gentle urchin]

macro

indexes will go out of sync tho

1,2,3,4

Removes index 2

1,3,4 remains

Removes index 3

1,3 remains, when it's 1 and 4 that should've remained

[slow pewter]

but how i can fix it?

[slow pewter]

Simple Macro, so i can C/P ist

[gentle urchin]

find the correct index that the object is located at.

this array is BasicGameplayFeatureDataInformation struct, right?

clearing and repopulating the list would solve this

[slow pewter]

Yes in the SG directly

[slow pewter]

but thats more Work, and for what i want to use it it could be an Huge amount of Reordering Work

[gentle urchin]

So instead

you must implement a find method

So you find the correct index to remove based on some variable

[slow pewter]

Yeah but i Remove like its Stored when i Remove Actor 3 with Index, 3, ITs all Assigned Correctly, So ,

it should work Correctly

[sharp rapids]

You can try using a map

🤷‍♂️

[gentle urchin]

Not when indexes fall out of sync...

When you remove an index, you shrink the array

[sharp rapids]

Having indexes as keys would work, wouldn't it?

[gentle urchin]

yeah that'd work

[slow pewter]

Yes, i understand that ,

So there sno Simple Sorting Method?

[gentle urchin]

So then you understand the issue ^^

[slow pewter]

i never worked lots with Maps tbh

[gentle urchin]

All you need to do is loop it, find the first instance with matching X, and remove that

[slow pewter]

so you mean not the Direct Remove Index Node, more than Check array, For Each LOOP; get the Index, and Remove the Item ?

instead of remove index?

Sry im more Artist then Code ppl, still learning it

[sharp rapids]

It's similar to Array, Just that you don't have indexes, you have keys
In an array, you have a value at index [0], In a map, you have a value for the key [0]

You can remove a key and it wouldn't affect other keys

[gentle urchin]

Something like this

I just used a random struct

[slow pewter]

THanks bro i will try it !

[robust kelp]

thes macros?

[gentle urchin]

Functions

[graceful holly]

How can I clamp the falling velocity? Doing so I get errors

[brittle spade]

is it possible to set some values in the create object node?

[gusty shuttle]

@graceful holly Perhaps changing air friction based on time falling?

[graceful holly]

mmmmm, not exactly what I want I guess. But I dunno

[hollow gorge]

What's considered "good practice" to handle the persistent parts of a player's inventory?
Should GameInstance handle the main data to persist from level to level and then save/load progress to/from SaveGame to carry over from previous sessions?

[robust kelp]

whats the blue one above player charactor?

[patent plover]

I have a problem with this. If the player is walking in the colider the first time, it works and the player takes damage. However, it doesnt work the second time I walk in the colider

[hollow gorge]

Please also send the "take damage 5%" part of the code.

[patent plover]

yes, just a sec

this is the code

[hollow gorge]

I personally find it a bit weird to handle armor and health this way.
Try adding various "print string" nodes within your code and see up to which point your code gets executed.

[patent plover]

oh ok

[hollow gorge]

Don't forget to change the text within the print node so that you know which one fired.

[sharp rapids]

What values

[slow pewter]

Ok @gentle urchin my Problem was that i Was thinking that my Object Index stays always the Same, after Removing Index, after Index Remove, my Array Index 2, was Object Index 3 etc, now i Assign everytime the Object Index Based on the Array Index, now works flawlessy

[robust kelp]

omg imn so happy my movement works :).. now to get animation to work

[gentle urchin]

The character movement component. A component within the character template

[robust kelp]

is what it allows me to do doesnt let me use im assuming multyplayer indexin?

[gentle urchin]

Pretty much what i said all along , isnt it? :p indexes coming out of sync

[slow pewter]

so Map would be like array, and when i remove SOmething it wouldnt, get Reorderd , and Index 4 stays at 4 even when 3 is removed?

[gentle urchin]

Anyways, glad you found a working solution

[slow pewter]

Yes Bro exactly

[gentle urchin]

Map is key/value pairs that can be randonly ordered

But you will always get the same value for a given key

Untill the value for the keynisnupdated, ofc. Or pair removed

[slow pewter]

Ok but i guess for what im use the Array is the Perfect Case, i just doesnt need an Object Index, bc u always have an Array Index

[jade sedge]

Some Help?

[slow pewter]

U have an Specified Row, and Column, for that Position

u mean something like Grid Panel or?

[patent plover]

@hollow gorge This regeneration code is causing problems. It is basically regenerating the player as soon as it has damage.

so how to make it regenerate after sometime it was hit?

nvm I got a solution myself

I cant find the delay node tho, it is not apperaing when I rightclick

[hollow gorge]

to find the delay node, just type in "delay" and you should find it right away

[patent plover]

oh, ok, looking at some issues tell me that we cant import delay node in functions

[hollow gorge]

Yes, you can't use delays in functions. Use them in the event graph if you need them

[hollow gorge]

Something else: In general I'd recommend avoiding event ticks where possible and use an event driven design approach instead to save performance. That way you probably wont need a delay either

[patent plover]

oh. But I would need a delay if I want to start regen after 1 secs of when the last time the player got damage, right?

[hollow gorge]

The way your armor currently works also bugged me for a while, do you intend it be more like a "shield/absorb" effect? Because you always set it to a reduced value after taking damage. Just wondering.

[patent plover]

no. what I am doing is making only the armor regenrate not the health

I have like 2 health bars

[hollow gorge]

Yes that's probably a good use for a delay. Also make sure you have a way of checking if you're currently regenerating (maybe add a boolean) that way you don't regenerate multiple times.

[patent plover]

thats exactly what I am doing

tho I cant get this visual scripting to work, cause I switched from unity and I am used to coding in c#

@hollow gorge how to access a variable in another GameObject?

[icy dragon]

GameObject?

[hollow gorge]

DM me directly and I'll look at it more, let's not flood chat lol

[icy dragon]

What the hell is GameObject?

Was it an inherited class from UObject?

[hollow gorge]

A Game Object is probably the equivalent of Actor in Unreal Engine but I'm not sure

[obtuse herald]

https://docs.unrealengine.com/4.27/en-US/Basics/UnrealEngineForUnityDevs/

It says "Actor, Pawn"

[icy dragon]

Can't found it even in C++ classes

[hollow gorge]

it's from unity not unreal engine 🥲

[obtuse herald]

it doesn't exist in ue4, he's using unity language

[obtuse herald]

Anyways, I don't know how stuff in unity works, but in unreal engine you need a reference to an actor (game object) to access it's variables

[icy dragon]

Oh... So it's from Unity vocabulary...

[hollow gorge]

Wrong reply, it was @patent plover who was asking

[obtuse herald]

aaaaa

I'm getting confused

[icy dragon]

Being so used to UObject being the supreme class and not necessarily for gameplay, "GameObject" felt weird

[obtuse herald]

yeah, I know

[echo salmon]

Is there any website explaining BP nodes in details. (except unreal docs) ?

[thin panther]

only one I know of is Mathew Wadstein's YT channel

[dark crow]

Pinned in #ue4-general

[rare gale]

Have you tried using a timer? On damage, set a timer to the delay you want and then run the code you have there as either a function or linked event.

[robust kelp]

is this outdated? i cant fiund the node calculate direction one i find is green and doesnt hook up like this

[dawn gazelle]

Yes. You can use the green one just fine, it just doesn't hook up into the execution path, but can still be connected to your direction node.

[robust kelp]

ah okie

little things confuse me somedays

[safe musk]

hello everyone, can i delete those folders and keep this another's (green box) to "clean and reset" project status ?

[keen hedge]

Is there a way to expose Child Actor Component's child actor variables in the editor, when selecting the parent component that contains the child actor component?
I can only see the parent's variables in editor, and clicking the child actor component from the editor doesn't show its variables either, I can only change the child actor class there :/

[gentle urchin]

Also its probably risky to base jumping state etc on a keypress and not on actual state change (e.g. in air etc)

[robust kelp]

you happen to have a more upt o date better guide? im just trying to follow unreal doc learning etc

feel like im beating my head agents an outdated wall

[odd ember]

no and it's recommended not to use child actor components

you're better off attaching actors to actors

[keen hedge]

Thanks for the tip! I suppose there's no way to do so from the editor/blueprint editor, rather only via blueprint nodes?

[odd ember]

you can do it if both actors exist in the level

otherwise you can use Expose On Spawn for variables to expose them on the spawn node in the graph

[keen hedge]

Thanks!

[patent plover]

uh how do I access a variable in one game object in a blueprint script in another? (sorry for my unity jargon)

[odd ember]

those blueprints have to communicate somehow

I believe there's a pinned link to this channel on blueprint communication

[patent plover]

yeah, found it. Thank you

@odd ember, uh the vid is 2 hours long, and rn I cant give that much time. Could you tell me what is the problem here?

[odd ember]

you need an object to cast

casting doesn't magically provide you an object

[patent plover]

this is the error

[patent plover]

? Cant I just call the ThirdPersonCharacter class from another gameObject?

[odd ember]

nope. the reason the stream is 2 hours long is because it is going over the basic understanding of programming that you need in order to do blueprint communication

and I'm not about to repeat that

[patent plover]

oh ok

[odd kiln]

Hi all

How can I make my TPS camera not following my Capsule Component please ?

[rose citrus]

Hello. I posted this question in Paper2D, but I would like to ask here as well. I have a parallax camera that follows me around and it has been working fine for me. When I set up the camera on the level, I add all the objects per layer that I want to move slower or faster, and then on event tick it sets all of their locations. The problem I just found out I have is I can't get it to work on level streaming. It only works when I load a whole level by itself without level streaming/as the persistent level. I created a dungeon generator so it's very important that every room has it's own camera. What I don't understand is the camera on the streamed level doesn't have the actors I added to the parallax array, so when I play and close, it gives me an error that is accessed none. So basically, my parallax array that I set in the camera's details panel on the editor is not registering, or maybe it can't find the sprites? I don't understand why. I tried putting a delay on the camera's begin play in case if the camera loads before the whole room is loaded, but that didn't fix it BTW, If I load the sub level directly(without level streaming) the parallax works, that's the part that confuses me.

[marble echo]

anyone have any idea why I can't change the parent class for this blueprint interface?

[jade sedge]

Yes, like a grid panel, and I have columns and rows variables of each item. I know that I have to make and array but when I do, it don't obtain anything.

[vast urchin]

How would i go around setting a max velocity on an actor?

would it be a clamp?

[cursive path]

I set up the load game but i have problem with put time or date when the save file created and level of character

[unreal tusk]

Hey fella's, I'm trying to think of some better logic or a better way of approaching this.
I'm wanting to make it so that every 5 ranks the xp needed to get to the next rank is a specific amount.
Instead of doing this sequence where it just checks where if greater than 5 ranks, change experience needed to 2400, if greater than 10 ranks, change experience needed to 4800.
If instead I can setup an array? Or some good mathematical equation for this? You'll see in my second screenshot, if I could put a nice math equation here under the branch where every 5 ranks it makes the input true followed by the SET Var Experience Needed as another equation where if rank is X follow this array of experience needed?

Honestly just kind of spit balling, not sure how to approach this.

[unreal quail]

is there an equivalent to the meta UPROPERTY flag EditCondition in blueprint?

[safe musk]

There is this "warning" when build a project, but i don't have this object in my game, how can i find it and delete it ?

[unreal quail]

Var Experience Multiplier = Floor(Rank/5 + 1) * 2400?

[gentle urchin]

Change parent class? Why?

[bleak swift]

Is there anyway to detect if a user is on mobile like a bool?

[gentle urchin]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Game/GetPlatformName/

[vast urchin]

Anyone?

[unreal tusk]

the 2400 experience "multiplier" isn't really a multiplier so I don't think this would work.
Basically, ranks 0-1 takes 800 experience, ranks 1-2 takes 800 experience, ranks 2-3 takes 800 experience. This is the same up until rank 5. Which then ranks 5-6 takes 2400 experience. Ranks 10-11 takes 4800 experience, etc.

Used multiplier for lack of a better term to be honest haha

[unreal quail]

then if Rank >= 5 you can use my function else ExpPerRank = 800

[unreal tusk]

Right, I can do that for each step of the way, just was wondering if there's a better way than that.

If not that's fine.

[unreal quail]

If (branch) Rank >= 5 (true:) ExpPerRank = Floor(Rank/5) * 2400 else (false:) ExpPerRank = 800

[unreal tusk]

ahhh i see. Yeah I'll give that a swing, might be able to get something outta this.

[unreal quail]

your exp function is a little bit weird I would have assumed something that scales up somewhat linearly but your initial value of 800 is off here

if you could make rank >= 10 require 4000 exp it would be even more straightforward

[unreal tusk]

yeah, I'm doing an odd end system where, every 5 ranks you gain a level. Doing this since my game is based off of Dungeons and Dragons and I'm trying to stick pretty true to the rule set. So the max level is 20. So I want the players to have something inbetween each level since each level will take quite some time.

[unreal quail]

it'd be ExpPerRank = (Rank/5) * 1600 + 800

[unreal quail]

I see

and DnD doesn't have a formula to scale exp per rank?

[unreal tusk]

DnD doesn't typically have a ranking system, it's just levels 1-20. But since I'm going to have to drag those 20 levels out throughout the course of the game. Trying to spice it up with ranks inbetween each level.

Gonna tinker around with your formula there and I might make what I have currently a little more, exponential instead of specific.

[runic parrot]

Hi! does anyone know if this is a reference or a new array?

[unreal quail]

ah I see, but I rather meant exp per level in this case

I assume it depends?

[unreal tusk]

It kind of varies, there isn't really a linear experience scale. It's kind of random? ish? lol I can toy around with the numbers though, a simpler leveling system may help here. If you're interested I'll show ya what I end up coming up with probably with some variation to your formula.

[unreal quail]

as you wish 😁 the one I last gave you should be somewhat interesting I think but as a rule of thumb you can use Floor(Rank/5) to get the DnD "level" and then play around with it :p

[rose citrus]

I do Load Level Instance for level streaming a random dungeon. The problem is that when I load an instance of a level, a blueprint in the level doesn't keep the array of actors I set in the details panel to reference other actors in the level. It only keeps it if I load level, but then I can't load multiples of that level. Is there a way around this?

[maiden wadi]

Were all of the assets in the loaded dungeon a part of the same level?

[rose citrus]

yes

Every room has it's own camera, and every camera keeps an array of several background and foreground actors in the room for parallax reasons. The array doesn't keep the actors I set when I load an instance of the level. I kind of understand why, because if multiples of that level are loaded, how does the array know which actors it is referencing, the actors in level instance #1 or level instance #2 (if that is even how it works).

[marble echo]

i can't add the hit actor to the target, thought changing its parent from interface would help

[last abyss]

that is the wrong call anyways, you need the one with the mail icon

[gentle urchin]

The message one

Not sure what this one does really?

Is it like a local call of the implementation?

[marble echo]

it's the 'interface' call apparently, its the only one i can use

[gentle urchin]

Drag from hit actor

Interaction(message)

Might need to untick context sensitive

[marble echo]

ah yeah, context sensitive was it, thanks

[vast urchin]

Anyone Have any resources to help me figure out bhopping? besides this http://adrianb.io/2015/02/14/bunnyhop.html

[marble echo]

can anyone think of another way to go about this instead of the 'bind event to'? another blueprint interface maybe?

[teal talon]

How do I take something like Fog and be able to toggle active/visible/density from another blueprint?

[gentle urchin]

Whats up with the get class from instigator etc?

Make a return function in the interface to pass the ID back to whoever interacted with itn

I showed you a working example of this

[marble echo]

trying to get it to feed into that bind event, but since it doesnt know what's been clicked it wont accept it

yeah ive been looking at all of that, trying to set it up

[turbid apex]

Do some of you like to use Metasound?

[gentle urchin]

This part

[marble echo]

is send card to instigator another function of the bpi?

sorry its just all mega confusing. i should probably start a new project but i have so much other, working stuff in here

[gentle urchin]

Yes, it is ^^

The naming of that function was pretty bad, but i hoped to get across the gist of it

[marble echo]

alright, i'll try copy it out

sorry just another thing, what node is this?

[gentle urchin]

Its just a variable,

of type int

[marble echo]

ah i see

[gentle urchin]

Wait

there's a mistake in it ofc xD

You must use the "index to Remove" as the "Get" index, after picking a random!

otherwise they will not match

Like this

[marble echo]

got it, thanks so much again

[fair magnet]

I'm a little confused right now... if I want an event to run only locally (cosmetic event) do i still have to replicate from server to client?

[marble echo]

so I have this now, but still not sure how the deck is supposed to know when it's clicked like this?

unless the longer part is supposed to be on the deck bp?

[fair magnet]

I might be able to help you :o Would you like explain what your problem is in detail and what you'd like to achieve? ^-^

[gentle urchin]

Event Interact should be implemented in the deck, not in the player controller 😄

[marble echo]

it's a game where the player clicks on tiles and moves around a board, and every tile clicked reveals a card from a deck. i had it 'working' but it really struggled knowing which tile i'd clicked on so this is a workaround about that i think

[gentle urchin]

So the Deck recieves the "Interaction" message , does its thing, and returns an ID in the return event "Send Card ID to Instigator"

[marble echo]

i think im starting to understand it a little more now

having the card ID stored like that should be really helpful

i just tested it with 3 deck-tile-things and it recognises them each as seperate things which is great

[gentle urchin]

sweet

[fair magnet]

So essentially what you're doing is:
InYourController -> GetHitResultsUnderCursor -> Message Interface Function
which then executes the stuff you need on whatever you clicked on

[bold sedge]

can i add a custom depth pass to a terrain?

or do i need to apply it to the material?

[marble echo]

yeah, this seems like a good way to do it. before, it didnt seem to actually recognise which i’d clicked on and just picked a tile from random

[fair magnet]

I'd also recommend to not hard-code your input events. Players might want to change these

[marble echo]

oh for sure, this will be a mobile game eventually so it’ll be changed to touch at some point

[fair magnet]

Good Luck

[safe musk]

Guys, in my old and low configuration PC, the Unreal 5 (early access 2) i felt its was hard for my pc config. but i want to know if now in this new version is more optimized for low config pc ... tks

[gray quarry]

Hi guys! Can you give me some hints on how to spawn projectiles that move in a spiral outwards from the player?

[marble echo]

is something like this how you'd approach the cards blueprint? to check if its ID has been drawn?

[barren flower]

In a radius around the player?

[gentle urchin]

Not sure what there is to check?

Like... the card would just be told " You are card of ID 'X'"

[barren flower]

create the projectile attached to some spiral projectile blueprint, move the projectile away from center relative to the center of the blueprint internally, and rotate the blueprint in world space

[marble echo]

this is how I checked it before, not sure of a better way tbh

[gray quarry]

Oh, never thought of two separate motions, I am so stupid sometimes, thanks!

[barren flower]

I have one, how would you store multi block structures in a voxel world. So say I have a minecraft style world, how would I have a, say, water tower thats a few blocks wide, few blocks deep and like 8 blocks high?

So lets say I interact with the side of the tower, how do I store that in such a way that the game knows that block is actually part of a larger set?

[gentle urchin]

'But like.. why check? Why not spawn the correct type and let it be it .. ?

[barren flower]

nah, youre just thinking about how to do it in meatspace thats all

[hollow gorge]

Does anyone know of some "good" inventory system tutorials? Would appreciate any recommendations!

[fiery ridge]

Is there any way to find a variable named X on an actor and if found, do something with it? (like subtract int/hp)

[barren flower]

Dont do that. If you have to, there is, you can cast to it, but even asking that question tells me you need to read up on classes and inheritance. You should know what variables each class have

the best approach, and what I think you are trying to invent accidently, is is a blueprint interface

[fiery ridge]

Well, I'm trying to think of an automated system where a "bullet" fires a function and in that function, it will look for the target's integer variable (Health) and remove some of it

[barren flower]

Yup, absolutely not

Blueprint interface

[fiery ridge]

So interface is the way to do it?

[barren flower]

the bullet should just sends its damage and armour pen stats and whatnot through a blueprint interface at whatever it hits, and that should triggger an event in the target if it impements the damage interface, otherwise ignoring it

[fiery ridge]

yes thats exactly what i am trying to do. thank you for clearing it up. learning interface now

[hollow gorge]

Why not use the "actor overlap event" for the hitbox instead?

[barren flower]

You still need to do that, but on the bullet, not the target

if it overlaps, it should then send the interface message to everything it hits

[rocky plume]

Is there a way through blueprints to get a list of files from a directory?
I'm trying to get a list of .sav files in the savegames directory

[barren flower]

those things should then decide in what way they should react, if at all, to that information

[dawn gazelle]

This one is pretty long, but he does a pretty good job of explaining how to do it all, from picking up items, storing in your inventory and a slot-based UI.
https://www.youtube.com/watch?v=yxqSkFNAzE0&list=PL4G2bSPE_8uktjEdP4ZuRq5r2o4JMdZfM

[hollow gorge]

wouldn't it be better to check for player / npc that has been hit to avoid an interface?

[barren flower]

I dont think you understand what interfaces are, they are just blueprint to blueprint messages

[marble echo]

but where can I designate its ID in its blueprint other than backwards like this?

[hollow gorge]

Thanks, will give it a look

[fiery ridge]

no because i get this issue

[barren flower]

you only send the messages to objects the bullet is overlapping, not everything in the entire gameworld

[hollow gorge]

I always thought in terms of programming, interfaces wrap around the actual class, therefore using tons of interfaces could be bad practice

but maybe I'm mistaken, gotta look into it

[barren flower]

From the targets perspective, its just a custom event, with information passed along also

[fiery ridge]

@barren flower how about event dispatcher? Is it better than interface?

[dawn gazelle]

Using interfaces allows you to be able to send a signal to multiple types of objects without having to know their specific class, and having those objects react differently to that particular event.

[fiery ridge]

Okay that is exactly what I was looking for. Thanks

[gentle urchin]

The CardDeck would spawn the card, and tell it about its ID

[barren flower]

Event dispatchers are a horrible way to implement damage from a bullet. They have their place, but honestly I dont think ive ever actually used them in practice. The problem there is that every single thing needs to specifically be setup to do stuff, rather than just either implementing a damage interface, or not.

Like, if you want your walls destructible, implement the damage interface, and it will receive hits when stuff shoots hits at it, otherwise dont. Its class agnostic, which is its biggest strength, it doesnt care what it hits, it only care if its listening or not

[fiery ridge]

That's good to know, thank you ❤️

[barren flower]

So a player can die, a glass window can shatter, an energy shield can glow and shrink, a steel knights shield can dent, and the bullet doesnt have to know about any of that crap, it just sends its velocity, its damage and its penetration to anything that says it gives a shit when it overlaps

[marble echo]

but if i had 6 different bps, surely all of their events would trigger when any card is sent to instigator?

[gentle urchin]

Sounds like you'd wanna pass on a class instead of an ID really

a subclass of "card"

[barren flower]

No thats extremely wasteful, each card can have an integer value as an ID, theres nothing wrong with that approach at all

Just have a generic card class with variables for stats/images and whatnot, thats totally fine

[barren flower]

Are there going to be duplicate cards? Can I draw the same card with the same ID potentially?

and whos asking, who needs to know if the ID has been drawn?

Potentially you can have the card be aware of what spawned it when you create it, and add that information to an array in the parent object if its like a game table blueprint

Is it the deck blueprint? To see its remaining inventory or something?

Theres a few approaches potentially, but its really a game design question, I need a bit more information as to what exactly you are doing and what to achieve. I would approach a poker set very differently to magic the gathering

[fiery ridge]

@barren flower can I ask you, where do you think it would be best to store armor, damage, etc if they are meant to be changed (upgraded). Gameinstance?

[gentle urchin]

Depends on what they need the cards to do really

If its just stat lookups, then ID into a DB would work wonders

If its a lot of custom events, you'd need (want) custom classes to handle that

[marble echo]

yeah, i'd want it to be able to have duplicates in the deck. The card BP is asking the deck if its number has been drawn basically, and will do all the actions in that BP if it is. Ideally I want all unique cards to have their own BP

[barren flower]

In whatever needs those things, if its the player, put it in the players character blueprint. Dont worry about interactions between blueprints so much, the best practice is to just send events to everything and let them do what they may with the information

[fiery ridge]

Thank you

[gentle urchin]

The deck keeps a list of cards (either ID's or classes, whatever fits your needs)

[barren flower]

Im confused as to why this would ever need to happen, the card should be able to infer it exists by its existence, and should be told what it is on creation
