blueprint

[pallid nest]

well that makes me feel better and not that dumb hahaha , many thanks

thank you I will try

[hollow cove]

or if you're dumb like me and play everything on 2x speed because you're impatient, dozens of times

[lunar sleet]

I think the worst ones are the sped up ones, that have music, and you have to manually slow it down and listen to garbled sound

[pallid nest]

well I did x2 with the tutorial so that obviously increases the chances to do mistakes but with casting my brain goes that slow that I can't go 2x 🤣

[distant hollow]

Oh I hate those with music and minimal explanation

[hollow cove]

also, why does every tutorial on youtube start with "hey whats up guys" and make you have to turn it up 2x higher than everything else

"first were going to create our project and im gonna make you sit there for two minutes while i do that"

[pallid nest]

I thought it was just me being super impatient hahaha

there is one guy I love his tutorials because he is super quick, 1 min most of the time

[distant hollow]

Mathew?

[pallid nest]

Royal Skies, not sure about his name

[hollow cove]

i like those but they're too fast sometimes. mathew is about the right speed tho. i just try to be grateful that theres any information online at all and it brings down my stress a little.

[distant hollow]

Ah, not Mathew

[hollow cove]

cant imagine what it was like trying to learn this stuff back in the 90s or whatever

[distant hollow]

Textbooks

[lofty rapids]

i went through a tutorial and he kept messing stuff up, and fixing it at the end

[distant hollow]

That was how we used to learn

[hollow cove]

they had to actually read words printed on pieces of wood?

[distant hollow]

Yes lol

[hollow cove]

[distant hollow]

I started with BASIC in like… 1991-ish?

After that it was GWBASIC

[lofty rapids]

quick basic was awesome

[distant hollow]

Then C and Pascal in 97

No such thing as YouTube

Internet is kinda minimal

Those were the days lol

[hollow cove]

i feel like it must have felt more special to learn programming back then, being on the cutting edge. when im learning i just feel like im trying to catch up to kids who learnt what i have when they were like 14

[void sentinel]

So I have a question that I imagine the answer to is stupidly easy, but I'm having issues finding an answer to it

[lofty rapids]

people had big books that had all the stuff in it, bibles

[distant hollow]

Ngl it was fun

[pallid nest]

but I think he is also one of my favorites (you refer to Matt Aspland I assume?) with another one called Gorka. I recently discovered also a guy really like although his tutorials area reaaally heavy and long but I think are very good (Ali Elzoheiry)

[ebon olive]

ohh i see. so player 0 bascially means the main player character?

[distant hollow]

Yep that one

[ebon olive]

no. i just want to figure out what this do because in the future, i wanna add more characters then swap around 😄

[distant hollow]

Oh wait there was another one

[pallid nest]

again im not the best to ask as too noob here but to the best of my knowledge yes

[distant hollow]

Wadstein or something like that

[void sentinel]

So a few days ago I followed a tutorial which I thought I understood all of the things used in the video, but apparently I don't.

The issue is this, I have a component variable, but it's still returning as nothing.

I'm missing a step somewhere

but I don't know what it is

[lunar sleet]

You just possess them manually at that point. That’s for when something gets initially spawned in

You’ll prly want to keep that turned off for later additions so you can possess when ready

[void sentinel]

For some reason it doesn't allow me to select BPC_Inventory

[lofty rapids]

you mean it's not valid ?

[ebon olive]

oh okie! noted. thank you!!

[void sentinel]

Yeah

[distant hollow]

You need to set a default value to it

[void sentinel]

Yeah, but it won't let me set the default value to BPC_Inventory

[lofty rapids]

where do you set it ?

[distant hollow]

That’s not how it works
You need to have an uasset

[void sentinel]

Would a uasset be the actor it's attached to?

[distant hollow]

Not actor

An uasset in your contents

[void sentinel]

Ah, I don't fully understand what that is yet, would just casting be a better way to refrence this variable?

[distant hollow]

Are you using a plugin?

[lofty rapids]

what is that variable supposed to represent ? you need to set it's value somewhere

get actor of class maybe ?

or what parent class for bpc_inventory ?

[void sentinel]

So I was looking at the tutorial again, realized I'm an idiot.

and confused two things

ended up basically copying what they did for BPW_InventoryGrid and BPW_MainUI to communicate with eachother now, which is a funciton.

[ebon olive]

huh i dont get it

why this #include got an error??

it was working on my previous script before

[sonic crest]

Sometimes when I get problems with include I ignore them, after I build it works fine

Or I add ../ or just /

Not sure why it sometimes needs it

[thin panther]

well you don't really want to ../ much in unreal

[sonic crest]

It sometimes fixes the red squiggles

[thin panther]

Do you have EnhancedInput in the module your in

[ebon olive]

okie i will try that one for the time being. thankss

[thin panther]

don't

[thin panther]

The red squiggles are false though, and this is in Rider, which is good at knowing #includes properly

[ebon olive]

no but when i hover it, it says to add module to enhancedinput though 😮

[ebon olive]

ohh okie

[desert juniper]

Did you add the EnhancedInput module in the build.cs file?

[thin panther]

So add EnhancedInput to your module's build.cs, you need to do that whenever you want to use it elsewhere (because unreal uses sort of false include paths)

[sonic crest]

It fails to compile on my end :/
Visual Studio 2022

[thin panther]

if it fails to compile, find out why

if it can't open the include path, correct it.
A ../ or a / will never be the solution

[ebon olive]

nope

[floral stump]

Why i can't cast to Item Drag And Drop ?

[ebon olive]

ohh add onto that build? okok. thankss

[ebon olive]

okie i will take note of this asd w well haha

[sonic crest]

Include file not found
Putting ../ fixes it.

[thin panther]

again, that's rarely the solution

what file are you including

because there's nearly always a better way in unreal land

(except a few very very very exclusive situations for your own code)

[zealous moth]

what are you trying to do?

[sonic crest]

Some Enums and Structs but I haven't worked on the project in a while

[sonic crest]

Maybe you forgot to compile? Or are the stuff in C++ and not visible to BP?

[floral stump]

get Object Item Drag And Drop from Item Drag And Drop Operation

[zealous moth]

@floral stump is that a component, a scene component, a variable?

compile your other class you are trying to cast into

and it should appear unless it is private

or "Local"

[floral stump]

seems like you don't have experience with UI ?

in DragDrop we generate payload and assign it to DragDropOperation

[zealous moth]

did you cast correctly?

you wrote "DragAndDrop" but you cast in "DragAndDropOperation"

[floral stump]

its not even getting it in the list

[lofty rapids]

what are those circles all about, what kind of bp are those ?

[thin panther]

show the folder structure for them in #blueprint

[lofty rapids]

and it looks like they are seperate

[floral stump]

what i am doing in here?

[sonic crest]

Is the object input compatible

[floral stump]

that operation should get the drag drop class

[ebon olive]

helloodid add it and my inputactionvalue.h greyed out. is that right?

[floral stump]

ofcourse not, in other user widgets i can cast it

[zealous moth]

that should'nt matter, when she drags off the pin what she is looking for isn't there. I suspect it's the wrong cast

[lofty rapids]

i mean if it's a blueprint you can look at what your casting to

and check if it even has that variable

[zealous moth]

look at the names of her lists she had earlier

they are all named the same except for the suffix

and it's not what was originally asked

[floral stump]

this is from another widget

[floral stump]

yes

[zealous moth]

well wait if it works in the other

why not copy paste it?

[lofty rapids]

you can see it gets the payload and casts that, something your not doing in your code

[floral stump]

uff

yeah my bad

that payload was needed

thanks

can't believe how i missed that

😂

[faint pasture]

also you're adding torque 4 times per frame

not sure if that's what you want

[pallid nest]

I finally found the issue @lunar sleet @distant hollow @lofty rapids , such a silly billy sausage. The widget reference (ACMSkilltree) is created in a function that I was excluding from my BP character for testing purposes . Thanks again for the help ❤️

[abstract mango]

Not at all, I'm applying it max 2 times due to I'm basically having an input, multiplied by the torque strength, the poduct of that then is applied on button press, 2 times, one for y and one for x torque

[crude timber]

How can I get the previous index from a For Each Loop ? I'm trying to get a position of a previous index, so I can draw a path

[lofty rapids]

your not using index but maybe you can get index-1

or store the last whatever you need in a variable

that you can use on each loop

[thin panther]

Take the array index, - 1, ensure it's a valid index

[crude timber]

Ah ! Didn't tick in my brain doing a simple -1 and getting the array again after

will try, thank you !

[lofty rapids]

just make sure it's valid on 0 will be -1

[crude timber]

That worked perfectly \o/

[lofty rapids]

theres also storing it in a variable

[crude timber]

this did the trick for me

got a proper cable network with it :p

Do you guys have issues with Tags sometimes ? I feel like they're not reliable

Pretty sure I have it setup correctly and the Get all actors with tag returns me zero

Printing the length of the resulting array and it's nul

[desert juniper]

I’ll get called out for shameless shilling 😈, but rider is a phenomenal IDE. It would have warned you what the problem is, and included it for you.

[ebon olive]

it greyed out once i add enhancedbuild to the build. Stupid question sorry so greyed out means i can remove it yes? 😅

[desert juniper]

Greyed out means the IDE thinks it’s not being used/called. You can normally delete it, but every once in a while the idea is just wrong and it is in use

Comment it out and build. If it works, then delete the line

[ebon olive]

Oh so basically it's stored. Okok thank you so much!

[zealous moth]

Don't listen to him, he is shamelessly shilling for Rider. Notpad++ is the only true way to go.

[desert juniper]

Pfft. Speak for yourself. Real programmers use wordpad

[zealous moth]

can character BPs if you use C++ not have their meshes set anymore in 5.3?

[blazing kettle]

Has anyone tried to send a blueprint interface message from a list widget item? I'm trying to get information back to my player character but it seems to fire on the list item end but doesn't reach my player

[zealous moth]

show code

[zealous moth]

where is the pink window to change it?

[blazing kettle]

This is the widget initialization

And then this is the message code itself

I've checked and it does fire when selected

But doesn't send the message to my player

[zealous moth]

is it set to false somehow?

otherwise your target isn't loaded or in memory

[cyan tiger]

hey guys is returning to me how can i make it 24 hours not AM / PM?

[blazing kettle]

Ii've troubleshooted it and that branch does fire when the item is selected, and surely the object must be in memory if it's my player character?

[zealous moth]

try a hard reference

that or your player ref is never set?

print string it and see if it exists.

and either way if you use a single player ref, use the "get player character" or controller function

[frosty heron]

If you never load the soft ref, resolving it will just return null ptr afaik

[frosty heron]

Can , why not?

[zealous moth]

create a C++ project, brand new. Add in your folders a new BP of class "Character" and open it

can you edit the mesh's SK?

in the editor, not the construction script or through nodes

@frosty heron

mine doesn't appear to have it at all

[frosty heron]

Sorry I'm in bed, but will try tomorrow.

I have a project in 5.1 tho and I can edit the character mesh.

[zealous moth]

yeah i do too, but in 5.3 it's just elsewhere it seems

[frosty heron]

5.3 a bit cursed, I'm not gonna upgrade yet. There is a bug that wipe the detail panel in that version

[spark steppe]

there may be a format node, but not sure

otherwise it just picks whatever your system uses

[cyan tiger]

Ben my system uses 24 hours format... it is weird

[supple dome]

looking at the code, theres a param for which style to use, however BP always call the default style (from current culture ie. console command culture en)

[foggy basin]

how do I check if the player's inventory array has space left over before adding an item to the slot?

[fathom gull]

Hey, I’m trying to have walking and running speed in two fixed states with the analog stick. So that when the left analog stick is turned a little bit in a direction the character will walk in a constant speed, and when the left analog stick is turned a lot, my character is running in a constant speed. I have it working but only on 4 directions, I would like to have it diagonal (and any direction) as well, what’s the best way to do this?

[rugged wigeon]

@fathom gull read the X and Y axis of the stick. Length of the XY (think pythagorean theorem) is the speed. Round that off as you wish to be either 0, walk, or fast. Direction is just the direction of the unit vector of those two

[rugged wigeon]

compare length of the array to whatever you want the maximum to be. presumably you mean "in game max" and not "data structure max".

[still swallow]

Is there a way to not see and expose variables of an expanded node ?

I dont want Weapon Actor Reference to be visible, just like in switch node

Where unused conditions can be collapsed

[foggy basin]

I don't know if Lenght will work, because when you start the game you already have 6 slots (which is the maximum)

[rugged wigeon]

so it's an array of 6 slots then. You're not changing the array, you're changing it's components?

[foggy basin]

yep

[fathom gull]

How would I implement that when using this as input?

[outer brook]

Hello fellas. I have a question regarding "inheritance" in combination with "BlueprintComponents":

Let's say there is an actor "BP_Base" which owns a BP-Component "BPC_BaseComponent".

Now I would like to create a "BP_Special" which inherites from BP_Base. But I want the BP_Special's BPC_BaseComponent to inherit from "BPC_SpecialComponent". But I would like to set the reference between these BP-Components within the BP_Special without adding a new Component in in BP_Special. Instead, I would like to somehow set the inheritance of the component in another way... it's hard to tell what I mean but I hope someone understands me here!

How would you accomplish this? Is that even possible?

[lunar sleet]

No idea what you mean. If Base has the component, Special will inherit it, the end.

If you add a special component to Special, then it’ll have that too

[outer brook]

Yes but in my scenario, BP_Base has the BPC_BaseComponent attached, not BPC_SpecialComponent, which should stay this way. But I would like the BP_Special to change that without adding a new component to it. Instead, it should use the BPC_BaseComponent of BP_Base and change it's type to BPC_SpecialComponent.

I do not want to exclude the possibility that I misunderstand something or that I made some logical mistakes regarding inheritance, maybe?

[lunar sleet]

You’re trying to fight the inheritance system. If you don’t want it to inherit, don’t make it a child of it.

You cannot change inherited components, most you can do is change default values of inherited variables

Maybe don’t have a base component to begin with if you’re going to change it anyways. Otherwise, you can always just plug in variables into a function in that component, so you can change their values on each child as needed, rather than trying to replace the entire component (which is not possible if inherited)

[outer brook]

No wait, i do not want to "replace" the component. I would like the BPC_SpecialComponent to inherite everything from BPC_BaseComponent so I can use all variabls and functions in BP_Special AND (!) everything from BPC_SpecialComponent.

It seems like there is no other way then adding BPC_SpecialComponent directly into BP_Special from the start. I just hoped, I could somehow define the specialization of that component in BP_Special in reference to the parent's base component...

[rugged wigeon]

You want to make it a 2D axis input. two separate 1D axes.

[outer brook]

Anyway, thank you so far

[rugged wigeon]

@outer brook You definitively cannot do this.

Most likely your design has not utilized components correctly if you feel this is necessary.

[outer brook]

Yes, I am slowly coming to that conclusion too haha. It helped to talk/ask here.

[balmy kraken]

Say I have a class structure like this
NPC (with inheritable event called Die), Die does some basic action
--Bear_NPC (inherits from NPC), Die does some additional actions on top of parent actions
--Spider_NPX (inherits from NPC), Die does some additional actions on top of parent actions

and say I want to do call Die on NPC as I don't know what child it is at the time, how do I have them also perform the child Die event?

[rugged wigeon]

it will do so automatically

your grammar here is a bit confused though.

Bear is a subclass of NPC.

You have an instance of a bear.

Something kills the bear. It doesn't know it's a bear. It only knows it is an NPC. So it calls NPC->Die.

But it's still a bear. And bears call Bear->Die, not the parent class implementation, unless Bear->Die explicitly class the parent class implementation too

tl;dr you don't need to know the subclass of an actor to ensure it calls it's subclass' implementation of things. This is always the case.

[balmy kraken]

hmm, i must have done something else wrong then, as it didn't happen as expected. is this true in blueprints as well as cpp?

or maybe i got confused because the engine kept crashing without saving :/

[calm bloom]

Hey anybody able to help out why my spawn actor doesn't attach to my character socket but just get placed into the map only?

[plain ingot]

Is it because 'get onwer'? I am learning blueprints for 1 week now. Maybe you need to put a get actor instead?

[plain ingot]

I dont know for sure but i want tk know it so i can learn from it

[foggy basin]

yes, what do I do now?

[calm bloom]

ah looks like i was trying to fix it at the wrong location. So my item have collision and what happen is that once it spawn it collide with my character and it doesnt attach it the player

[plain ingot]

Ohh

Can you send a screen of the working blueprints so i can see the difference

I am just beginner, sorry

[calm bloom]

the blueprint is the same

[plain ingot]

Oh

[calm bloom]

i have to remove the collision type from my item

[plain ingot]

Oh i see

Ok

Thx

[calm bloom]

np

[fathom gull]

Okay thank you, I have it working :)

[rugged wigeon]

iterate over your list of slots in a for each loop and check if all of them are empty. If any of them are empty. it's not full.

[lime crow]

I am making a projectile bp, but i will be creating child bps from it, i want to expoe these variables but not sure how i can do it (its just one variable and setting using that one variable) any ideas? Thanks

[rugged wigeon]

yes. In c++ it's made a little more obvious because you have to specify that you are overrideing the function.

It's kind of hard to crash the engine with blueprints outside of things like infinite loops too

[rugged wigeon]

expose them to what

all variables of a BP parent class are accessible to its children class

they won't show up under "variables" but you will be able to see them in class defaults and you will be able to reference them in the blueprint.

[balmy kraken]

something else i may be doing wrong. i frequently crash from errors including video memory errors.

with the stater 3rd person level and only a few character bps

[lofty rapids]

how much memory

[rugged wigeon]

is your computer good enough to do this?

[balmy kraken]

32gb mem and 5700xt radoen card

just updated to the newest engine 5.3.1 i believe. crashed 5 times same error today

rtx is off

[rugged wigeon]

is it a laptop

[balmy kraken]

no

[lofty rapids]

does it crash in the editor or when you play ?

[balmy kraken]

when i play, but not compiled

played in viewport that is*

[rugged wigeon]

Is it slow as a potato when it runs

[balmy kraken]

not at all

great performance

[rugged wigeon]

dunno. that's hard to say.

[balmy kraken]

3.80 gigahertz AMD Ryzen 5 3600X 6-Core
Samsung SSD 970 EVO 1TB [Hard drive] (1.00 TB)

[faint pasture]

That should do just fine.

[balmy kraken]

thanks for looking anyway. i was on 5.1 then upgraded cuz of the crashes, still happens

[lofty rapids]

5.2.1 runs great for me

[balmy kraken]

oh wait, new drivers. let me try that

[lime crow]

i see what you mean, the issue is its all one variable.

[rugged wigeon]

what do you mean its all one variable

your problem was wanting that one variable to be accessible in children, no?

[lime crow]

sorry for not being clear, i need to use separate variable to expose them all in the child blueprint, but im setting multiple particle spawns from one variable

[rugged wigeon]

I'm not sure I parsed that correctly. But I think what you're trying to do is track multiple particles and have them be accessible in th child class. But you don't want to make a unique variable for each particle.

The answer is probably to make your particle variable an Array of particle objects, rather than just one.

[faint pasture]

What are you actually trying to do, from a mechanics perspective?

When x happens, you want y to happen

[foggy basin]

it worked perfectly, thank you so much you are my savior

[lime crow]

I want to have exposed variables on a child blueprint. But because i am using one variable to set multiple particles in the parent blueprint, it wont work. I need a way to expose the variables for the different particles

[lime crow]

i think thats the way

[pastel skiff]

is there a way to make a delay in fuction?

[rugged wigeon]

No

[gaunt burrow]

howdy, anyone here familiar with cases of the event graph 'skipping' functions, potentially related to the bind event to onclicked function?

[crude timber]

Damn I just reactivated the Flat Nodes and the engine graphs feel way smoother for some reason

[gaunt burrow]

if so, I have a post up on the Unreal Forum here: https://forums.unrealengine.com/t/my-event-graph-seems-to-be-skipping-sections-but-not-always/1591683
where I've tried to lay out my issue. (that way I'm not clogging the chat up)

[rugged wigeon]

This is not really readable

At least not on mobile

[gaunt burrow]

Yeah, I'll see if I can get a cleaner pic, the single attachment limit was kinda rough

though, any version would require a lot of zooming, since I'm essentially trying to fit a large portion of my event graph into a single image

[rugged wigeon]

I see some binding, bear. Are you remembering to unbind?

[acoustic tundra]

Hi, I got a quick question on which I've been lost for some time. I created a hotbar with 3 slots. Each of these contains a border with an image. Whenever I pick something up in-game, the icon gets added to the image slot, but the background color of the image slot changes to the same color as the border color. So say the item is in slot 2, and I got that slot selected, the background color becomes yellow (same as border), but when slot 2 is not selected the background color is black (same as border). How can I make the slot's background color consistent so that it doesn't update the image color to the border color?

[lofty rapids]

how are you highlighting ?

with a yellow image ?

you only change border and it changes the whole thing ?

[acoustic tundra]

No, I have a int variable in my playercharacter called selectedindex, which I feed into the function of the widget. This is the code that updates the image slot

Then here I change the border color of the highlighted index and reset the color of the other 2

[lofty rapids]

what is border ? is it the whole thing ?

instead of a border ?

[faint pasture]

use select node

and probably an enum instead of an index but it depends

[heady burrow]

is it possible to configure a decal to ignore certain objects but not others, like, discriminating by actor name or type.

[acoustic tundra]

The border is the green line, image the blue one

[lofty rapids]

does the border change that whole inside black part ?

could be going behind the image

and is the icon transparent ? and that's what your seeing ?

[echo dirge]

WASD key navigation in widgets.
Does anyone know what onKeyDown override function I can use in Blueprints to make the navigation go Right for D keypress and Left for A keypress for example?
Is there a Node I can call on that will move the navigation Right Lefy Up or Down in the Widget?

[acoustic tundra]

this is what happens

[lofty rapids]

ya it looks like the border is actually the whole thing

so when you put an image in there the transparency shows the actual background

you could probably fix it by putting another square behind it of a solid color that you want to use

[acoustic tundra]

but how does the slot stay as gray when there isn't a texture assigned to the image?

[acoustic tundra]

so at the start

[faint pasture]

What are you actually trying to accomplish? The variables are exposed already. What end effect are you trying to achieve?

[lofty rapids]

i think you set all that in your details

are they images ? or what are they ?

[acoustic tundra]

They are images yeah, and I have given them a color in the details pannel

but what I find weird is that at the start the border goes around the image, but when the image is updating the border fills the image

[lofty rapids]

probably because you gave it a color

and then you switched it to an image

[ancient siren]

does anyone know how/where (if there are any) tutorials on how to make a spline that you can customize in game?

[gaunt burrow]

ok, updated the post with some better pics I hope

https://forums.unrealengine.com/t/my-event-graph-seems-to-be-skipping-sections-but-not-always/1591683

ok, made one last tweak because the first image still seemed a bit wonky, still works best on pc though

[lime crow]

All good bud, i need to use arrays i think.

[midnight field]

Is there a way to retrieve a parent actor from a state tree's task blueprints? I'm having trouble locating any such function.

[lunar sleet]

You can add components at runtime if that’s what you want. But yeah, otherwise use 2 separate components or modify variable values.

[lunar sleet]

#gameplay-ai for these questions, more specialized help

[midnight field]

Fair enough.

[solid needle]

how can i generate a random int without repeating the number

[thick glacier]

Hey gang, I'm messing around with game templates for the first time in ue5.2, I'm having a issue with changing my third person character mesh. when I change skeletal mesh in viewport details it does not change in game mode. any tips on what i'm doing wrong?

[hoary junco]

if I have a camera that's separate from the player character, how do I make it so the player character's movement direction is in the direction of the current camera angle rather than the world direction?

[frosty heron]

random int in range is a pure function, it will always output a random int in the range everytime it is called

[solid needle]

without repeating

[frosty heron]

you can cache the number then

from the out value, promote it to variable. Use that variable instead

[finite hearth]

What is the advantage of using a trigger box vs. a collision box? I need to fire an one-time event when something enters the box. Should I use trigger or fire an overlap event of the collision box? Is it the same?

[native canopy]

how to fix the item is over the box?

[frosty heron]

use uniform grid panel for a grid panel

[native canopy]

the item pile up

[mental trellis]

Why is there a random top knot?

[native canopy]

?

[native canopy]

that character hair

[mental trellis]

I see.

[native canopy]

my problem is the item pile up

i know the problem but idk hwo to fix

if pickup new item the item icon is moving column

[mental trellis]

Add brushes to every slot that have no image / transparent one / set to invisible. Add those images to an array. Position them on your UI.

Then simply set teh right icon in teh right slot based on the index of the array.

[native canopy]

not liek that

[mental trellis]

Shrug it's a perfectly workable solution.

[native canopy]

this using horizontal box

[native canopy]

i want make like this but using unoiform grid box

Horizontal box is not a good idea.

Try a grid?

[native canopy]

this using unofrmgrid

[native canopy]

@mental trellis this is using gridbox, but the item not change their column when add new item

[mental trellis]

That looks very much like you're adding them wrong.

When you add a slot to a grid it defaults to 0,0. You need to set the row and column when adding it.

[frosty heron]

have you assign the row and collumn?

[native canopy]

every add item that in 0,0

[frosty heron]

Then, what do u expect?

[native canopy]

i dont knwo the code if add new item the column add 1

[frosty heron]

You know what a row and collumn is right?

[native canopy]

when add new item the column add 1

[native canopy]

ms excel have that

[frosty heron]

You need to fill them up

say you have 30 slots, add 30 Empty slots to it

like an empty item that is represented by empty icon

[mental trellis]

You could even add the image widgets in those slots to an array so you can access them sequentially.

[mental trellis]

Like this ^

[native canopy]

i get that

[mental trellis]

Also #umg !

[native canopy]

i know, make an image alpha 0, when add new item change the image fill

[mental trellis]

So design your UI in the umg editor, don't make it dynamically.

[native canopy]

but i dont knwo how to make the code -_-

[mental trellis]

Code to do what? You design the ui in the wysiwyg editor.

[native canopy]

when pickup item the image change

idk how to do that with 8 image

[mental trellis]

Expose the image widgets and set their properties from your hud variable.

See the pins in #umg to learn how to do these things.

[native canopy]

ask in that?

[mental trellis]

The pinned messages in that channel

So I made (followed a tutorial xD) a building system where I want to implement a delete building system, but apparently it destroys multiple objects, not just the building, how do I fix this?

[frosty heron]

Your floor probably has BuildItem Tag too

don't really like the tutorial tbh, I would handle deleting on the building it self. Have a function to delete in the Building.
Player can then just tell the actor to call the delete function

[proven dune]

Ohh you are right! ( I didnt follow the tutorial for the deleting, did it myself, but thanks for the correction! 😄 ) I'll try that!

What Class should I cast to though?

[proven dune]

The floor doesnt have a BuildItem tag btw

[frosty heron]

print string the actor befor deleting

see if the floor gets printed

if not it could be another code somewhere

[proven dune]

Good idea!

ill try

Ah I see, here comes a plot twist

It doesn't print anything

[frigid jetty]

Is there a good way to connect an array element pin to a fallback struct structure pin from a For Each Loop to a Create Widget? I'm pretty new and have been following this tutorial. It works if I rebuild it by replacing the Create Widget and then compile it but for some reason it breaks when I close the editor and reload the project.

[frosty heron]

Ctrl F , type destroy actor then hit the binocular icon

determine which one cause the floor to be deleted

[proven dune]

Oh wow, never seen that before

lets see here

I see! The delete system isnt what deletes the floor

Ill debug a little

I think i see where it is coming from

[frigid jetty]

Oh wait I figured it out. I had to set my widget to active.

Lets go!

[proven dune]

How could this be?

[frosty heron]

Don't think so, this makes no sense what soever

so if it's not valid destroy it? I mean you can;t destroy nothing

[proven dune]

Yeah that makes sense

I've got this blueprint

https://blueprintue.com/blueprint/w66__fej/

[native canopy]

can i use this for RMB? without LMB

[frosty heron]

No, afaik that's a callback when widget is clicked (with LMB)

[native canopy]

have other way to maek RMB for ui

[frosty heron]

You probably want to store hovered widget every frame.
Then On Right Mouse Button Released -> Check the hovered Widget -> If Widget == This button, then do X

[native canopy]

?

check hovered widget?

[frosty heron]

actually can't get the hovered widget

there is, IsHoveredWidget however

OnRightMouseButton Released -> If This Button is hoevered -> Do X

[native canopy]

working but need double press

[clever rose]

Hello, I'm having issues with my character movement. I was following a tutorial that was setting up 8 directional locomotion and it works fine for him. However, if I hold down W, my character is stuck moving in one direction no matter which direction I'm facing. The same goes for A, S, and D. Can anyone help me out? I know this is a dumb question but I'm pretty new

[frosty heron]

How so?

you probably don't have focus if you need to do it twice

on hover -> Set Keyboard focus

[native canopy]

typo

i mean that working but need double press

[frosty heron]

#blueprint message

[native canopy]

how game use unreal like apex when using item need to press ui with RMB

[frosty heron]

No idea, don't have their source code

if their code is leaked, someone can just make a copy of the game

I would make a base Widget that have the functions I described

that way you can make a right clickable button as many as you want

[hoary junco]

is there a way to restrict a character's movement so they can only move within a navmesh? Or is the only way to restrict movement using things like walls and blocking volumes?

[dark drum]

What type of game are you making? Ultimately, only characters controlled by AI can fully use the nav mesh. (You could use the simple move to but it's limited)

[hoary junco]

it's an isometric puzzle game set in cyberspace, so the level is built of a bunch of platforms sorta freefloating since that's the aesthetic. The character can't jump so I've already turned off their ability to go off ledges but even when I do that the character model is kinda half hanging off the ledge when I go to the edge, I'd like it to stay fully within bounds so I was going to use a navmesh for that

[hoary junco]

the white box is supposed to represent the character model when it's dimensions are done, and as you can see it's kinda hanging off the edge

[dark drum]

Does the character move by the player clicking where they want them to move to?

[hoary junco]

no, WASD movement

[clever rose]

Hello, I'm having issues with my character movement. I was following a tutorial that was setting up 8 directional locomotion and it works fine for him. However, if I hold down W, my character is stuck moving in one direction no matter which direction I'm facing. The same goes for A, S, and D. Can anyone help me out? I know this is a dumb question but I'm pretty new

[dark drum]

I'm not aware of anyway to use the nav mesh in the case then. You might need to implement your own ledge detection system. The one built into UE uses the capsule center (hence why it overhangs the ledge).

[dark drum]

You'll need to provide more information about how you move your character and the 8 directional locomotion setup.

[hoary junco]

if I were to add a box collision is there a way I could make the existing ledge detection system to use the outside of the box collision?

[dark drum]

You could just put an invisible collision around the ledges but that sounds like effort when you change things lol. If the player is walking into a wall you wouldn't need the ledge detection.

[hoary junco]

I know but my first platform is octagonal in shape and I was trying to add blocking volumes but it was an absolute pain in the ass

[dark drum]

Yea, a custom ledge detection system would probably be better long term. It would just be a case of doing line traces down at the edges of the characters capsule component. Trace from the bottom and then end the trace that's slightly larger than the step height. If it doesn't hit something, it can't go that way and adjust the input movement accordingly.

[hoary junco]

I have no idea how to do any of that 🥲

[frosty heron]

There are climbing mechanic on youtube. You can draw some ideas from there

[clever rose]

I followed this tutorial https://youtu.be/PtuT6R4WM6Q?si=banyLwWDLgBbiG61

[timber crystal]

Hello friends
I'm really at my wits' end when it comes to a flying opponent

So now I'm just trying to program a projectile movement so that it moves in the air in my direction.
My question is, is it possible to tune a projectile to move as soon as it sees me, i.e. with Pawn Sensing?
i upload my Bp image
Because the problem is now taht it moves in my direction but not if he sees so at the begin of the game he starts to move

(I know that's not the right way for a flying opponent, but I'm still far too new to unreal to be able to do everything without being able to see the whole thing in a video or picture)

[bold flax]

So I am working on a spawn system for my multiplayer game and trying to get a reference to the player controller from some logic I have in the level that runs on begin play. How might I do this? I am not wanting to put the logic on the player itself becasue I only want this spefic logic to run when the player loads into this specific map. Each map handles spawning differently.

[main flume]

Hey there

I want to check if my bool has changed from the last two seconds (if the player doesn't move the mouse for 2 seconds, the cam resets). I made a function for checking if the mouse is moving but I can't seem to find a solution for the timing thing...

[versed sun]

A Retriggerable Delay might help, but it has to be in an Event , not a function
You could use the Triggered of of your mouse input @main flume

[main flume]

Oh okay, thanks, how would I use the event there then?

Sorry if its a basic question, I switched from Unity to Unreal a week ago

[versed sun]

I think you are on the old Input system, so you would add it in Input Event LookUp and LookRight

[main flume]

I am using the enhaned input actions

[versed sun]

so, whenever the mouse moves , it resets the Delay
if you don't move the mouse, the Delay is allowed to finish

ok, so in main graph, add your inputs

[main flume]

Where can I find the delay though?

[versed sun]

you wont see Delay nodes inside a Function

[main flume]

ohhh

[versed sun]

has to be in the Event graph

[dark drum]

Something like this.

[main flume]

Like this?

[versed sun]

nope

[dark drum]

Why do yo square the input value and then square root it straight after?

[versed sun]

Under your tick , right click and type LookUp

[main flume]

only positive values

[dark drum]

just abs it.

[main flume]

Ah thanks for the tip!

[versed sun]

there you go, plug both Triggereds into the Retriggerable Delay, and unhook it from Tick

[dark drum]

Is there any reason you're using two sperate input actions for looking around?

[main flume]

Currently not really

[dark drum]

It might be worth putting them into one to help simplify things.

[main flume]

Ill look into that! Thanks

[dark drum]

The project templates use just one if you need an example.

[main flume]

This still doesnt seem to work

[dark drum]

Using a timer would be the best option. (look at my example above)

[main flume]

Oh I found out

I need to put it into started instead of triggerewd

since triggered is tick based

[versed sun]

the Code after the Delay will fire after 2 sec after no input

[main flume]

How would I set the mousenotmoved there?

[main flume]

Yea my mousemoved is a bool though

ah oh nevermind

[uncut seal]

how can I smoothly update an objects transform? i tried the following, but it was still very jittery) I also attached a video showing the jitter that I want to fix (starts at approx 20s)

[dark drum]

Yea so you have a bool you set to true when you start moving and then set it to false when they stop. The other stuff is just to reset the cam after 2 seconds which is independent from the looking bool.

[dark drum]

is it being updated on tick?

[uncut seal]

It is.

[dark drum]

O you'll need to swap out the vinterp to the constant one if the end location moves. It jitters because it's trying to smoothly interp the values but the following tick the end location has changed which messes up the smoothing it's trying to do.

[main flume]

Now the cam instantly resets after I stop moving my mouse

[dark drum]

then it's being called somewhere else.

[main flume]

This is how I use the variable in the cam

[dark drum]

Move your camera movement stuff off tick and add it to the triggered on the input action. Some of these checks can then be removed.

[main flume]

They need to be on tick though, cuz I got some camera movement, based from the speed

[dark drum]

Triggered calls each tick but only when the player is wanting to move the camera. (pressing the input button)

[uncut seal]

it still seems to be jittering, and increasing the interp speed only makes the train slower. yes, it will be smoother, but i need it to be fast

[main flume]

Yea, but the car still has a speed even when the player isnt moving the cam

[dark drum]

What are you trying to do with the camera regarding the speed?

[main flume]

Basically if the car is going faster, the cam is moving upwards

[dark drum]

So this should only call when the player hasn't move the cam for x amount of seconds?

[main flume]

Yes

and the normal camera movement should be called otherwise

[versed sun]

This should be all you need
You can read the Is Moving? on tick if you need
And 2 sec after not moving Reset Camera will trigger
You should learn timers , but they are overkill for what you need atm
Simplify and build from there

[main flume]

oh thanks

[dark drum]

In which case, create a new bool called 'bShouldResetCam?' when you call the 'ResetCam' function, set this to true. In the function where you check if the cam is moving, check if it's false and should reset cam is true.

[main flume]

Thanks alot, this works perfect

[main flume]

Yea the other solution from @versed sun worked perfectly though

Thanks for the help!

[uncut seal]

I just realised that the locomotive doesn't lag at all. this is being updated in the tick function, but all of the others are actors which get spawned in by the locomotive, do lag. I think this is because they are being updated in a for loop, meaning they get updated 1 * number of cars times slower. ill do some testing to make sure this is correct, and then i may need some help

[dark drum]

I'm not a fan of the ambiguity in the vars such as 'IsMoving' being true for an additional 2 seconds even though technically it's not. Just be careful as you continue to add stuff as you might forget there's actually a delay in the IsMoving being set when they stop.

Here's the other solution in case you have issues.

[dark drum]

Are you not attaching the additional actors to the locomotive?

[uncut seal]

no, im not sure how to do that

[dark drum]

When you spawn them, attach to the locomotive and they'll move with is so you wouldn't need to manually update their locations and rotations.

[uncut seal]

but wouldn't they be in a straight line? the rotation is based on a spline and it has curves which is why i did that

[dark drum]

If the base locomotive rotates, so will everything attached to it.

[uncut seal]

thats the problem. the cars at the back of the train shouldn't rotate when the front of the train does, because it isn't up to that part of the track yet (where it curves)

[dark drum]

Ooo, i get what you mean. I thought the jittery carriage was the front of the locomotive lol.

[uncut seal]

no, the front is perfectly fine, but somethings up with all the rest

[dark drum]

You could try having the front carriage controll how much the back carriages moves forward. So if the from carriage moves x forward along the spline, all the other carriages move x distance along the spline. That way you can remove the interp as you wouldn't need to lerp it.

[main flume]

Thanks!

[uncut seal]

ill give it a shot, thanks

[lyric rapids]

im trying to make it so when the player steps on this actor it will change its material however its not working does anyone know why?

[frosty heron]

Print string the other actor, make sure it gets called

[humble tulip]

hey developers, im trying to call an event in a blueprint from a blueprint but for some reason im getting some errors.

thanks in advance!

[frosty heron]

you are trying to access BP Lamp Gas station when it's not set

it simply doesn;t know which BP lamp gas station in the world you are pointing at

[true pendant]

Hi guys, I made a switch between camera, the first one is on the character, the second one is attached to a socket on a weapon (to create an aim down sight), the one on the player works fine but when I switch I loose the pitch control on the weapon, I can look left or right but not up or down. Anyone has an idea ? (I have an anim off set that works on the player I though it would follow with the other camera?)

[humble tulip]

the only thing i have is this variable thta has a type of the blueprint

but how can i set it?

[frosty heron]

using the set node

[humble tulip]

like this?

[frosty heron]

Nope, this is very wrong, you are setting it to it self

So nothing to nothing is nothing

[versed sun]

how are you choosing what Lamp to use?

[frosty heron]

XD That is such a perfect pic

[humble tulip]

i know its wrong but i didnt know what to do

[frosty heron]

Well which BP lamp Gas station do you want to Turn State?

there might be 1 - 2 - 3 or hundreds of BP Lamp Gas station

[humble tulip]

every BP lamp Gas station placed in the world

[frosty heron]

you need to set the Variable to one of them

[versed sun]

You are pressing E to use it , so i assume you are looking at it/ mouse over it / close to it?

[humble tulip]

no, its a switch, where the switch turns off/on all gas station lamps

[frosty heron]

Then you want to make use of arrays

but if you don't know how a single pointer works, an array can probably wait

[humble tulip]

something that points to the memory location of variable right?

[frosty heron]

An object reference (Blue pin) is a pointer

BP lamp Gas Station pointer, points at a BP Lamp Gas Station Instance

[versed sun]

This would get all

[frosty heron]

^ That will work to turn off all the BP lamp gas station but you better off learn how to use array later because there are times where you don't want to turn off every BP lamp gas station in the world

[versed sun]

This would get what you are moused over

This would get Lamps close to you

[humble tulip]

wow

[dark drum]

Eww... Get All Actors of Class. 🤮 lol. Yea it definitly would work but not recommened. 😛

[dark drum]

Assuming the lamps are placed in the level by yourself via the editor and not spawned at runtime, create an array var of type of your lamp on your switches and set it to instance editable. In the level with the switch selected, you'll see the var in the details panel. You can then add each lamp you want the switch to control that is placed in the level.

When the switch is toggled, you would just loop through the array and call the Turn State function.

[versed sun]

or..

[humble tulip]

The first part i understand but on my world i have spawned 4 lamps with same blueprint BP_LampGasStation, and now on the details panel when im selecting the lamps that i want the switch to control, i only select the BP_LampGasStation right?

[frosty heron]

Lamp(s) will require the use of array

A BP_LampGasStation variable will only point to one instance

[frosty heron]

Cool, how do you fill the elements? did you pick from the level?

If that's the case all you have to do is just For Each Lamp -> Turn State

[humble tulip]

no, i just clicked in dropdown and choosed the BP_LampGasStation, i assume thats not the right way

[frosty heron]

Show me the variable type, Did u select class or something

[humble tulip]

i select class, is the object?

now it worked

[frosty heron]

it should be object ref not class

[humble tulip]

now appears the lamps

worked!!!

[acoustic tundra]

Hi, I want to fire off an event in BP_Item_Flashlight from my playercharacter. I made a variable in the character of type BP_Item_Flashlight, but I can't make a reference as you can see on the right. Does anyone have a clue why?

[frosty heron]

Because there is no BP_item_Flashlight in editor time. It needs to point at an instance of BP_Item_Flashlight.
The Level is unreachable in the BP class because at editor time, the level is not spawned yet

[acoustic tundra]

Yeah usually I would assign the reference in the details panel outside of blueprint mode, but since I don't have the character placed in the level I don't know how I can assign it

[frosty heron]

Plenty of ways, but it all depends on your design

How is the flashlight spawned?

[acoustic tundra]

Currently it's just placed in the level

[frosty heron]

and how do you want to grab it?

[acoustic tundra]

Interacting with it (which already works)

[frosty heron]

ok show me your interaction code

[acoustic tundra]

it's early strokes, but this is it basically

https://blueprintue.com/blueprint/2iu6640h/

I got info about the items stored in a struct called ItemInfo

[frosty heron]

I assumed you get error here?

when did you even set flashlight

[acoustic tundra]

yesh but i was expecting that

accesed none trying to get flashlight

but i'm unsure how to set it, since i can't get a reference to the flashlight from my character

[frosty heron]

I'm assuming you want to Spawn the flashlight in that code?

if that's the case, you can get the return value from the Spawn actor node. That will be your flashlight (or w/e you spawned)

[acoustic tundra]

not quite, since that's the actor that gets dropped when I already have something else in my hotbar on that index, it just drops it (which is what the spawnactor is for)

but the actor that gets spawned from there I don't use, it's just dropped in the level

[frosty heron]

Then you should expand your interaction system

pass in the object ref of the item that is being picked up

that will be w/e u pick up. Including the flashlight

[acoustic tundra]

in the struct i assume you mean?

[frosty heron]

Create a new Input, call it Item_obj

in your pick up logic , pass in the object you are picking up

[feral night]

is there a simple way in blueprints to rotate a single bone in a mesh?

[acoustic tundra]

In thos one right?

what should the type be, since it could be anything that I pick up

[frosty heron]

It should be the base class of Item

all of your item should derive from that base class. FLashlight, food, weapon w/e

[acoustic tundra]

ah right makes sense

[frosty heron]

Yeah you can Set the bone transform in anim blueprint. That's how I make an NPC head to look at my player's head

[feral night]

Ah so I need to set up an anim blueprint?

[frosty heron]

Well for my case, I have to. Not sure with what you want to do

[feral night]

Ah ok thank you. 🙂

[acoustic tundra]

And from the class, I can then make it into an object target?

[frosty heron]

not sure what you mean

How are you picking up the item? By pressing button that do overlap checks?

[acoustic tundra]

so i got the class, how do i make it so it's a single pointer target

[acoustic tundra]

yes

[frosty heron]

what ever method you do to obtain the item, pass in what you are picking up along

[frosty heron]

An object ref is a pointer

it only points at an object

[acoustic tundra]

Yeah but I have the class input coming out of the event.

[frosty heron]

change it?

altough I don't know why u want the item

How I would do it is

Pickup Item -> Get the Item Info -> pass it to Player inventory -> Destroy the pickup item

Player use a weapon -> Spawn the weapon for the player

[acoustic tundra]

Because I want to run a custom event in another bp for which I need a target ref

[frosty heron]

yeah but why do you need that object you picked up on the floor. The object you pick up can just contain information about the item. If it's a flashlight, what hp and so on.
What I mean is you want to handle equipping in the Item Class

but anywayyyyy

you can still pass the object ref if you want

it's just not something I would do

@feral night This is the node btw

incase you need it

[acoustic tundra]

So in my case, I just want the flashlight to light up. I got a BP_ItemMaster and a BP_Item_Flashlight which is a child of it. Would I make the functionality of the flashlight in the BP_Item_Master then?

[frosty heron]

So BP_Item_master will have template events / function.

Such as Equipping/Use
Drop
Remove
Trade
etc etc

Each child (BP_Flashlight) or BP_Sword can handle the Equip Function differently

like Use on Potion will regenerate HP while Use on Flashlight switch it on

[acoustic tundra]

I see, and the bp_item_master would take the object class? Or how would it know what item should be used?

[frosty heron]

No the BP item master would just have the template function like mentioned

SO when you grab a BP Flashlight -> Use
It will run the version in BP Flashlight

[fringe junco]

Hmm so i am attempting to setup a camera for third person in an RTS, similar to the men at war series. I have most of the logic down but can't figure out which value to use to drive the aim rotation such that the camera mouse xy values drive the aim of the controlled pawn. any thoughts?

[rugged wigeon]

@fringe junco PlayerController->Get Hit Result Under Cursor By Channel

[fringe junco]

this is unfortunately not what i need. I need to drive something like the control rotation. the issue is that i dont have possess the pawn im controlling, as my controller posseses a camera pawn instead

[surreal peak]

Is that only one pawn you control

Or more RTS like where you can select pawns and tell them to do something?

@fringe junco

[rugged wigeon]

It is still probably what you need. Your units will need to have ai controllers that you will be passing indirect commands to.

[fringe junco]

theres both -- you have the overhead camera and the direct control camera

i have switching between both

i just can't figure out how to tie the player controller control rotation to a non-possessed pawns control rotation

which sounds obvious that u shouldn't be able to do this but

we'll see if theres a work around lol

[rugged wigeon]

it needs to be possessed by an ai controller

because it's going to be doing things when not possessed by the player

[fringe junco]

i have an AI controller setup cuz i have movement logic going

[rugged wigeon]

Ok, so have your player controller send cursor data to the ai controller which in turn uses that to determine where to look

[fringe junco]

like the basic feature set rn is:
0verhead rts camera with pan orbit and zoom
Third person camera with movement and animation
marquee selection and deselection

ah okay

the ai controller eh

[rugged wigeon]

My system has the player controller sending "Unit Order" structs to the AI Controller which reads the queue and executes them one by one. orders such as "move here" or "aim here" or "interact with this".

I would say you should probably do the same.

[fringe junco]

yeah an order queue is a good idea

im very early on, just trying to make a prototype

[rugged wigeon]

its going to be a big thing. Pick one or the other of RTS vs. controlled and just implement one on its own for now.

Although personally I think the whole "RTS where you can be a unit" just won't ever work conceptually as a game design thing.

RTS units don't fight in an interesting way. They sort of inevitably stand still and attack or kite and attack. Humans don't have the micro to handle things otherwise. It's too much. So if you imagine possessing a unit, it's really hard to imagine what the enemy ai should be. If it's dumb like RTS AI then it's going to be really bad FPS gameplay.

[odd kiln]

Hello all ! Does anyone know how to pass another float variable to the event "Apply Damage" please ? For example for a "Stun" amount

[fringe junco]

yeah fair lol

[rugged wigeon]

My thing is like a real time squad thing and my basic takeaway is that if you're asking people to control multiple units in a setting where you expect to do real time positioning, people will struggle to handle 3+ units

[fringe junco]

yeah, the only time this whole direct unit control thing worked for me was in like 4 player plus multiplayer coop matches where u split units

and thats specifically in that men of war series, idk if they have good ai or smth but its not so bad

[rugged wigeon]

You can just make your own apply damage

[fringe junco]

u are right tho, i think the micro makes it difficult for sure

[odd kiln]

Do I have to create an Actor Component ?

[rugged wigeon]

maybe. I haven't seen that game

[odd kiln]

I thought I could work with "Damage Type" tables but I don't really understand it

[rugged wigeon]

@odd kiln Probably this should be an Interface. An interface is a set of functions that you can say things implement. Like "Receive Damage"

[odd kiln]

Ok I'll try this, thank you !

[rugged wigeon]

Start by making a "Damage Interface". Give it one function called Receive Damage that takes, say, a float for damage and a float for stun.

Then on all the actor classes that you want to be damageable, go their settings and mark them as implementing the Damage Interface

[odd kiln]

That's what I'm trying to do

[rugged wigeon]

Then finally, you need to actually go into the bp and define what "Receive Damage" does for that actor class

[odd kiln]

Ok great I just have to replace my "Event AnyDamage" to "Receive Damage" event

[rugged wigeon]

yes

[odd kiln]

But I have to replace also my "Apply Damage" right ?

[rugged wigeon]

Yes, you would replace it with TargetActor->ReceiveDamage

[odd kiln]

Thanks a lot for taking time to help me ^^ I'll try this right now !

It works great, thank you very much !

[feral night]

Ah thank you very much! 🙂

[bold flax]

Got a question, wondering if its possible to hand the server over to another client if the server disconnects. Hope this makes sense?

[frosty heron]

#multiplayer but afaik. no.

if the host leave, everyone auto dc

[bold flax]

Thanks

[frosty heron]

Listen server is not the norm anymore anyway. Now days people use dedicated server

[rare shore]

Hi! I have an array that holds 3 elements inside when i save the game. I have it all on print string so i can follow it. Then i load and i see that those 3 elements are still there as they should be because there is no node in between that resets or sets the array to something else. The only node i have that is touching this array is ADD to the array, so nothing can ever get deleted right? So as i said when i load my game and the elements are still there BUT if i load again and again and again, it will stop working sooner or later. SO without dooing any changes to the code, after loading a few times ( sometimes after 2 loads, sometimes after 5+ ) the elements in the array just dissapear. I see it because my print string no longer shows them and they are really gone. What could possibly cause this? How can elements of an array just dissapear if they are once saved to slot? Everything else works, enemies, ammo, guns, etc.. i made it all work but this is giving me nightmares.. 😦 please help. thx🤘

[unkempt warren]

I'd just have a dedicated server instead of a "user" being the server.. So you don't have that issue..

Then any/all players that join connect as a client and you could have like an admin login UI or something..

[bold flax]

Thanks. Just looking to save on costs.

[ruby cobalt]

hello!

I want to send a duration in seconds and control a interp node with it.. not sure what the formula is

[bold flax]

Thanks. Just looking to save on costs. This is just a hobby project that I would love to be able to run on its own. I found that its possible and called host migration. Looks lilke there is some stuff on it.

[unkempt warren]

Sounds good, hope the best works out for you bud.

[bold flax]

Thanks man! I am seeing a pretty good solution that is for 5.1. So at least its possible.

[frosty heron]

players have to be re-connected even with that plugin

but I suppose that still an option

better than dc all together

[bold flax]

Thats okay. Having them reconnect is fine.

[visual crest]

What would the best way be to go about wounding a stat? Like lets say health's max value is 150 but you take 10 wound damage and now its max is 140, but that wound can be healed latter so max health will eventually be 150 again.

[frosty heron]

I would attach a buff that reduce the player's max hp

[visual crest]

Can you elaborate?

[frosty heron]

applying a buff that reduce player's max hp. There are many ways to do buffs, in my old project I use Dynamic combat system from marketplace, it already come with it. For my new project
I would probably use GamePlay Ability system GameplayEffect to apply buff

[visual crest]

Oh I see you mean just reduce max health by 10 then increase max health by 10 when removed? That won't work because I want to show it on the health progress bar as black or for mana as brown

[frosty heron]

I don't see why not, you can represent the black area as the penalty

A buff is just something you can apply to your system, it should be able to do anything code wise.
You can probably use component. Have basic features like if the buff is stackable, removeable, etc

[latent ridge]

Hello! I'm new here and encountering a problem with Unreal Engine 5.2. I've managed to spawn an actor at the point of projectile contact, but it's creating multiples at repeated points of contact instead of destroying the previous one. Attempts to destroy the extras haven't worked, as it doesn't validate their existence. Can anyone assist?

[remote meteor]

i suppose this is in the Hit event of the projectile?

are you spawning a new projectile each shot?

if so, the variable could not be the same, hence Last Perimeter BP wouldnt be valid

[frosty heron]

@visual crest Actually Gas already do what you probably want.
You can see the modifier on the Max health as well as the base

this one have duration, but it can be changed to infinite. And can always be removed with Tags (To remove the wound effect for example)

[latent ridge]

yea it's in the hit even and no im trying to spawn ad different object with when it hits another object and oh thats why so how could i make it valid

[visual crest]

I don't use Gas I made my own version of it.

[frosty heron]

well I can't re-invent the wheel (a worse version) , that's why I'm trying hard to understand this system

[visual crest]

Yea probably should of done that but I like knowing exactly every line of code does in my project lol

[remote meteor]

you could move these logic into the "firearm" or have the Last Perimeter BP variable saved somewhere else(maybe the "firearm") so you can check and remove it.

[fleet lichen]

Hello , Should I learn how to code, or are blueprints enough?

[frosty heron]

sure but there are times when you want to use abstraction. Some components of the game just take forever to make.
Imagine making our own movement system instead Character movement component for example.

[remote meteor]

essentially, you will need a system where it manages stats modifier/stacking
then a buff system for temporal buff/debuffs

and maybe percentile correction on Health when the MaxHealth is changed

[visual crest]

Yea your right I should probably used it but now I am to deep to turn back

[frosty heron]

Use Component for the Buff so you can apply it to not only your self but to enemies too.
On Buff Applied -> Do X
On Buff End -> Do Y

[frosty heron]

enough is rather broad. BP is enough to make a small scale game but you can hit the wall very quickly.
It's the trial version of unreal. The tool is made for designer

[latent ridge]

ok i'll try moving it some place else i wanted it only revolve around the type of projectile im using, but if thats whats causing the issue i could try making a BPI

[remote meteor]

for starters, i think you should localize this functionality to your HealthComponent, unless you can forsees you will need the same buff/debuff system for many other stats, then maybe think of a standalone Stats/BuffSystem
GAS localizes every stat you will possible need into the same Attribute system, so you could apply the same buff/debuff system to them

[visual crest]

I think what I am going to do is make a new stat for each health/mana/posture name it wound or degrade and then make its max stat = to its master and change its current stat to damage the max stat of its master. That way my health/mana/posture max stats can always be kept safe and no bugs that can permanently damage a max stat

[remote meteor]

essentially stats modifer stacking 😄

now i want to add a potion that will increase the MaxHealth by 50% for 3 minutes!

[paper gate]

Trying to orient the character to the surface normal, so that it's forward vector is pointing towards the surface. Currently running into an issue where -90 and 90 angles work, 180 and -180 degrees result in being rotated directly opposite to the surface and the inbetweens are, well, inbetween the two. Any idea if I'm even on the right track with my 'solution'. What am I doing wrong?

To get the 'vaultNormal' I am performing a line trace and taking the 'normal' parameter

I feel like I've scoured the whole internet for the solution, nothing though

[rugged wigeon]

You are trying to get your character to face the same way as the vault ledge, yes?

[paper gate]

Yeah, essentially. Something like this

[remote meteor]

you want to negate(multiply by -1) the normal then rot from x

[paper gate]

This seems to work. I'll do some further tests, but thank you

[faint pasture]

RinterpTo doesn't have a duration anyway

[rugged wigeon]

your speed should go to speed. Delta time from Tick (or some other time with delta time) should be an input to the function and it should go into delta time.

You don't want world time or anything like that.

you're just trying to say "I'm turning at x speed and it's been y seconds since the last frame so figure out how far I should have turned

[silk frost]

Hello everyone, I have a serious question about how to save the fact that when I picked up a flashlight, the save system would save it. I have already made a Save System and made it so that when you click “Save Game” it saves the “Player” data and when I click “Load Game” I teleport to save the player’s coordinates, this is of course good, but it does not save these things that I have already picked up please tell me how to fix this.

[sand arch]

I'm trying to recreate the cropout project that comes from the Unreal Engine example. But the enemies are crossing my building, does anyone have any idea what to do?
I'm using method AI Move To in Blueprint

[dapper galleon]

Hello! I can't figure out why this code doesn't remove the members from the array:

[broken wadi]

You're always removing whatever item is first in that array. Is that correct?

[rugged wigeon]

You need to… make some data to record the fact that you picked it up and save that too

[dapper galleon]

Yes, because it doesn't matter which item it is as long as the array is getting emptied

At first, I attempted to remove the exact item (the "Enemy" input on the event), but it didn't work either

So I switched to index, figured it'd work more reliably

But no, it just doesn't remove anything

[broken wadi]

Do you want to remove just a particular item or clear the entire array?

[dapper galleon]

Just one item per dead enemy

As the player kills the enemies, this event gets called again and again, and eventually, the array is empty, which triggers a second wave spawn

[silk frost]

That's the problem, I don't know how to do it 💀

[dapper galleon]

My only hunch is that like, I'm changing it but I'm not setting it?... But I don't know how to go about that, the "REMOVE INDEX" node doesn't have an output

[broken wadi]

yea you need to set the array again otherwise that node removes it but then keeps it in memory without actuallying applying the change back onto the array

[dapper galleon]

but how??

it doesn't have an output!

[rugged wigeon]

Well it really depends on your game. Does the game contain one flashlight like a Zelda game? Then maybe you just save a bool PickedUpFlashlight. If there’s a hundred different flashlights maybe you need to save a struct about all the items in the inventory.

[humble sleet]

???

the Remove node passes array by ref, so it directly changes the array rather than first obtaining a copy and changing the copy

hang on

nvm I think I misunderstood

[broken wadi]

yeah i think you have to set it again

[rugged wigeon]

Does the struct break provide values by ref though?

[humble sleet]

it's because you're operating on the result of a find node

[dapper galleon]

.....huuuuuuuuuuh.

[humble sleet]

this returns a copy

[dapper galleon]

Okay

So, what I need to do is

uh

[humble sleet]

so you need to set the value

map = key value pair

[rugged wigeon]

When you spawn a wave, store the current wave as a var

[humble sleet]

which you know since you're using one :P

[rugged wigeon]

I mean like yeah. That could work but generally speaking try to think of structs as immutable. Don’t edit things within a struct.

[humble sleet]

?

I use arrays of structs to keep multiple sets of data lined up properly

is that bad?

[rugged wigeon]

No

[dapper galleon]

Okay, that actually sounds like a really good advice
thank you

[humble sleet]

then I'm misunderstanding this

[dapper galleon]

Let me try doing this

[rugged wigeon]

I’m saying don’t edit content within a struct. Worst case create a new struct based on the old one plus a change.

[humble sleet]

ah

[rugged wigeon]

I mean I’m a functional programming guy but I think you should try to avoid mutating objects wherever possible.

Game dev requires otherwise but structs are going to be data and you can obey clean functional thinking there

[humble sleet]

OH I realised what I wasn't getting

rather than grabbing a book from a bookshelf, tearing out pages, gluing new ones in and putting it back

get the book, copy it with changes, put the copy back

[rugged wigeon]

Yes

[dapper galleon]

Oh my god IT WORKED

It worked, thank you so much

[humble sleet]

👍

[rugged wigeon]

Well for example right here we have someone getting confused because they were mutating an object that they thought was a reference but was in fact a copy

If you avoid functions that depend on something being pass by ref and treat it like data you’ll just have a cleaner workspace

To begin with I would try very hard not to have a stored struct (ideally immutable data) that has references to an actor (stateful stuff)

[humble sleet]

I realised some of that soon after I posted my message lol

thanks for the info :)

[ruby cobalt]

oh ok i didn't think there was a difference between delta time from tick and world delta..

[lament fox]

hello , this is the year integer but it looks like this. do you have idea how i can fix it ?

[versed sun]

year x 1000?

or, is it a comma for grouping

open up your Int to Text if you have it

[lament fox]

I think that will work 🙂

thank you so so much 🙂

I’m sure it’s in there or at least on a rich text box with some name in the same vein

[finite hearth]

Is there a way in BP to round floats to a nearest tenth? The only function is see is nearest int.

[humble sleet]

multiply by 10, round, divide by 10

you could even make a blueprint function library and make a pure function that can round to any number of decimal places

[finite hearth]

My very first thought

Ty so much

[slender dagger]

Can someone help me figure out a way to add and remove items from arrays depending on if they're spawned in or not? Basically I want to spawn certain power ups but not if they've already spawned in. And then add them back once they've despawned.

[humble sleet]

where are your arrays stored and where is the function that spawns your objects?

also show code if you have any

[slender dagger]

My array includes 4 power ups and are stored in my game instance, The event that spawns them is the death of a character in that blueprint. I'll post what I have in a sec

The array code is just off to the side because I wasn't sure how much space I'd need

[humble sleet]

well for starters I don't know what your random float in range is doing - that will always return true

[slender dagger]

I need to still plug the class in once I've found it, but I'm not sure which one I'm going to need. I've tried setting this up other ways and while I can get it to spawn the first time, It's spawning stuff with a different array

[slender dagger]

that's just for testing purposes

[humble sleet]

nvm then :P

I'm still trying to get my head around what you're trying to do

what is the desired effect?

[faint pasture]

If they currently exist or have ever been spawned?

[slender dagger]

so basically it has a x% chance to spawn a power up, when it spawns it, remove it from the array and add it back in after the power up ends.

[humble sleet]

ahh

[faint pasture]

Just for each class in your array, get actor of class, if it fails, there isn't one

[faint pasture]

When the power up is active, is the actor still around?

[slender dagger]

It's still valid yeah. Basically I only want the power up to be in the array if it isn't

[faint pasture]

Don't confuse an instance with a class

You have an array of CLASSES

[slender dagger]

the array is just in the instance blueprint. The array is made up of classes though

[humble sleet]

wrong kind of instance :P

[slender dagger]

oh wait

[humble sleet]

he means instantiated class

[slender dagger]

yeah i just realised lmao

[slender dagger]

wouldn't the get actor of class node in here deal with that though?

[faint pasture]

I'd do it like this.

Spawner:
PowerUpClassesArray

When you go to spawn a powerup:
For each class in array, add a copy to some other array if there's no instance in the world
That 2nd array is your array of allowed classes, get a random element and spawn it

[slender dagger]

lemme do a little mockup to see if I get what you mean

[faint pasture]

SpawnRandomPowerup -> for each element in PowerUpClasses -> get actor of class -> if not valid -> add class to AllowedClasses
-> finished -> get random entry in AllowedClasses -> spawn it

Don't do that on tick, just have like a 10s timer or whatever your spawning interval is

That's a quick and dirty way to do it

[slender dagger]

So I have power up and allowed power up arrays, Would the power up array be completely empty and the allowed one full?

[faint pasture]

no the first one stays full

the 2nd one gets filled every time you go to spawn something

you never remove any, just clear it after spawning

AllPossiblePowerups
CurrentlyAllowedPowerups

It can just be a local variable in a function

[slender dagger]

so something like this? The is valid goes back into the for each while the not valid just spawns the random from allowed.

Apologies if this is not at all what you're on about, never really done much arrays all that much aside from basic for each loops

ok I don't think that's worked. Ran into an infinite loop on the first spawn

got rid of the infinite loop

but it still keeps spawning duplicates

[lofty rapids]

why not just check on a timer if any are missing from a full array to respawn them ?

so have an array of all the powerups, remove from array when you destroy, loop through and create the ones that not valid

or they are all seperate classes ?

[slender dagger]

yeah they're separate classes

one is the parent so idk if that might help

I've tweaked it a bit so it doesn't duplicate but instead it just keeps missing one out instead

[lofty rapids]

so do you destroy the actor ?

[slender dagger]

so the power up spawns when one thing dies, you can choose to pick it up and when the power up is finished then it is destroyed

I'm just trying to make them spawn randomly and not duplicating it though atm

[jolly oriole]

Quick question - should I test for interfaces before trying to use them, or is that redundant?

For context, the above screenshot is executed when the interact button is pressed

[lofty rapids]

they all have seperate class names ?

[slender dagger]

yeah

[lofty rapids]

what if you kept an array of destroyed ones

so you could loop through that array to respawn

and just just empty out the array after

then add to it, when you destroy

[dim agate]

Anyone have advice on how to get this to continuously fire as long as the player holds down the input (right-click)? At the moment it just instantly turns the player character to where the mouse was when right-clicked, I want the player character to rotate to be looking at the cursor location while right-click is held down. I've considered event timers but wondering if there's a more efficient way.

[versed sun]

Triggered = On Tick

you want Started i believe

[slender dagger]

currently I have an array of ones that could be spawned at any given time.

[versed sun]

well, started for the Mappin Context part, Triggered for the Set Actor Rot

[slender dagger]

it looks like this atm

but for some reason it doesn't actually randomise

[lofty rapids]

what is the random connected to as far as the power

[slender dagger]

the output ref?

That goes into what's being spawned

[lofty rapids]

i mean on the execution it's in the loop body ?

[slender dagger]

both the not valid path and after remove go to the spawn which takes the random

[lofty rapids]

because your removing the element so if it's after loop body it will not work the array will be empty

[dim agate]

This seems to have worked. I was suspicious the answer was that simple, good thing I didn't waste time on event timers. Still a bit iffy when it comes to making inputs work how I want, thanks.

[slender dagger]

what would go there instead?

[lofty rapids]

are you removing if it's valid ?

you probably want to keep those classes of what you removed in an array

[slender dagger]

I've got the power ups and possible power ups, I was gonna remove them but neither of them work

[lofty rapids]

so you pick up power ups, and along the way you store them in array ?

wdym "possible powerups" ?

[slender dagger]

power ups that could spawn

[lofty rapids]

and that updates when you remove one ?

your possible spawns should be the ones that are destroyed right ?

[slender dagger]

I think? Whenever I've tried that it's not ended up randomising when I did that way

[lofty rapids]

show where you plug the random in

but you are removing items and trying to get random

but i don't see where that should matter, you remove the item, get a random, and then spawn

[slender dagger]

I also tried this one as well

[lofty rapids]

before you destroy the actor, save the classname in an array

that you can check and spawn whats in there

[slender dagger]

the actor isn't being destroyed for a while in this case

the power up is only being destroyed after it's effects have worn off

[lofty rapids]

right but you want to respawm it right ?

[slender dagger]

yeah but I don't want to spawn another one if it's already been spawned/being used

[fringe junco]

So im trying to setup a third person camera view switch in generally overhead RTS. the camera switch works fine, im just wondering how I can move the aim rotation of the pawn because i merely attach the camera to the pawn and dont possess them, but need them to aim lol

[split girder]

Hello im trying to create an execution system by playing another AnimMontage when the enemy is below 25hp, however if one enemy in my scene is below 25hp the animation always changes. Is there anyway to make this instance only, possibly with a trace? although ive tried to trace and couldnt work out what to do with the Out Result

[lofty rapids]

an array of needed to spawn would make sense, loop through the array and then clear it when your done

[fringe junco]

I have an aim offset set up an all, its just driving those pitch and yaw values. do i use the control rotation?

[fringe junco]

to use the out result you use "break hit result" and take one of the variables from it

[split girder]

I can get the instance and print it from the out result but im unable to get that instances health

[fringe junco]

hmm

[faint pasture]

why are you adding before checking if one is around?

Check, then add if there isn't one

[slender dagger]

that ends up giving me an infinite loop

[faint pasture]

Show current code

[faint pasture]

why are you going back into the loop?

[slender dagger]

to get another one that isn't valid

[faint pasture]

Do you know what for each loop does?

the loop body runs for each thing in the array

[lofty rapids]

do you have a variable on the actor ? or how do you store it's health

[split girder]

The Health is stored within C++ attributes file that the Enemy C++ class uses and then the enemy is a Blueprint child of that class

th health works individually

so i can kill different enemies and the health doesnt go down

[lofty rapids]

idk anything much about c++ or how you would get those "attributes"

[split girder]

but when i get a ref to that health in blueprint it is referencing all actors of that typ

type

[faint pasture]

show your code

[split girder]

thats the blueprint

[slender dagger]

so it randomises properly. Sometimes it spawns duplicates though.

[split girder]

but i see that im not referencing a enemy instance and rather the whole enemy class

but im not sure how i can reference a single enemy instance

[faint pasture]

That is referencing a single object

[faint pasture]

Show how Enemy Ref is set

[lofty rapids]

see how you sent attack type, send the actual enemy or just the health

if you can

[slender dagger]

is there a way to check the array every frame?

[lofty rapids]

yep

you could also put it on some kind of a timer though

[lofty rapids]

event tick ?

[lofty rapids]

that just gets the first one

[split girder]

I have 2 enemies, one 100hp and one 23hp in my scene, i want to be able to add a finishing move on the end of my combo if the enemy im fighting is below 25hp

But im not sure how to go about it tbh

[lofty rapids]

what bp is that ? character ?

[faint pasture]

@slender dagger

[split girder]

Thts in my AnimBP where my play Montages are done

[faint pasture]

Then make it be the enemy you're fighting, not just a random enemy from get actor of class

[split girder]

Im not quite sure how to do that

[faint pasture]

That's up to you

The enemy you just hit, the enemy you have targetted, whatever you want

In plain English, how do you know which enemy you're "fighting"?

[split girder]

targetted is a good call i have a target component on my enemy

[slender dagger]

Tested it a couple times, Randomisation works. But sometimes it just skips a power up entirely

[tropic peak]

Hey guys. I'm starting fresh with blueprints, and lets say I'm super new. I need a prod in the right direction. I decided to set a new task each week to develop a small functionality that won't really be used anywhere. I just need to create stuff so blueprints finally click for me. This week I'm making a "dice roll", and to determine what I rolled I figured I'd make a sphere at the top of each face, and the sphere that after rolling the dice has the highest X value would qualify as the roll result. (screenshot attached). If I wanted to add these spheres to an array, and compare their transform details .. how would I go about doing that?

[faint pasture]

Because they all are on the map

[slender dagger]

it will randomise 3 of them and only sometimes spawn the 4th one is what I mean.

[ruby cobalt]

not a pro here but here's how I would tackle it.. instead of creating the spheres manually, I'd spawn with an instance system using a for loop. I believe this would do the same as the array you're trying to build because you could fetch each instance via their index in a for loop or something

[split girder]

Ive set the last actor hit ref but now i cant access the variables?

[tacit rock]

Hello, when I make an open level it doesn't load my gamemode in the level because I can't control my character but when I launch the lvl through the editor it works.

[faint pasture]

That's an Actor ref, not a YourEnemyClass ref

You need to cast Hit Actor it to YourEnemyClass and save a ref of that type if you intend for it to always be of that type

[faint pasture]

Highest Z value, and just add them to an array on BeginPlay

[rugged wigeon]

Running with this design because of your stated goal… first off don’t do child actors like that. They’re kind of annoying and come with some baggage. Basically each “child actor” is more of a container so you’d need an additional node to get the actual out. For a task and implementation like you’re suggest use “scene components”, which are basically just transforms not visible at runtime.

[faint pasture]

Those aren't child actor components I don't think

look like meshes which are scenes anyway

[rugged wigeon]

Ah yeah. That’s more ok. But I would say use scene components properly to make it cleaner even for this toy example. No collisions ever. No visibility at game time.

[timber crystal]

@rugged wigeon i used now your way at it works!!! 😄 The AI ​​finally moves in the air. I've spent the whole day on it, but I would be very happy if you could watch the whole thing again over the next few days... since the AI ​​doesn't exactly move forward as soon as it sees me pounces on me from above but at least it's alive!!! 😄

I can then show you the new, functioning bp again; it would really just be a small finishing touch

But enough zzzz for today and thanks again for your tip 🙂

[rugged wigeon]

Anyway, since each of them is part of your class, you can reference them at any time in the BP. If you want to make an array of them you can do Make Array <whatever type> and then add pins adding your 6 elements manually.

You can use a for each loop on that array to iterate over each and track which is the furthest along your chosen axis on its transform -> location

[lofty rapids]

create the array on beginplay

you can just drag n drop
