blueprint

[glass magnet]

would it be a custom material?

ah well

im looking to draw out a space for these line traces and around the player

actually

could i use draw polygon and just trim off any parts the line traces dont reach

thats essentially what this person is doing but with triangles, at least thats how my brain sees it

[trim matrix]

wouldn't that work? can make a look with "Set Timer By Function Name" like this? (and have a check to clear the timer in the function)

i've seen a tut on udemy of someone doing it, but it's not working for me

[versed sun]

i don't think you want a looping timer calling a looping timer

[trim matrix]

if you mean the blooping is checked in the "Set Timer By Function Name" then i've tested it out without looping set to true

or you mean i can't do it entirely?

[versed sun]

sec , wife agro

[burnt canyon]

that is that self

that does not seem right

Won't the object it wants be a timer?

[dawn gazelle]

If you want to have your items separated out, then you'd should loop through your inventory and determine the types of items first and only add the ones you want to add to whatever categories. Right now it looks like you're looping through your inventory in your "UseItemList" and just adding all of your inventory, which may be part of the problem.

Here's how I would probably approach it for now:

Category Widget:
Contains a listivew for your items.
This should have a "Add Item" function for adding a new entry in your listview and the function should just take an integer input. The function will take the integer input and feed it into the Menu Item Object you are currently creating and then that object is added to the list view of this category widget.

ItemWidget:
Implements the ListViewUserObject interface and is responsible for reading in the data from the Menu Item Object. As it's now an integer, you just need to get the player's inventory array, a

Main Inventory Widget:
Contains your layout like you have above, (You have buttons for Items, Weapons Armors, etc.)
The buttons control a widget switcher. The widget switcher should contain a copy of the "Category Widget" for each category you have.
The main inventory widget on construct loops through your inventory array, reading the item ID and determining what Category Widget the tag belongs to and calling the "Add Item" function on that Category Widget, passing in the Inventory Array Index you are currently on. (ie. if an item in the inventory is Item.Consumable then you want to call the "Add Item" function on the Category Widget for the "Items" widget switcher). This integer will in turn be fed into your ItemWidget which can then read the contents of the array and display the necessary values.

[versed sun]

what calls your function the first time ?

[trim matrix]

left mouse click, it trace under crosshairs check if the trace item is interactive_item set it to player_physics_handle and then calls this function to set the location of the physics actor

[versed sun]

and what would trigger the stoping of the timer?

[trim matrix]

i was thinking of calling it again with bClearTime set to true, and branching it to see if i want to clear or loop the timer

the default value of bClearTimer is false, so it would loop if i don't pass it

[mild crystal]

anyone know why this isnt working?

[trim matrix]

i was thinking of making the set location on tick, but i only want to set the location 1/10 of frame rate. the tick will call it every frame

[versed sun]

so you want it to follow your mouse cursor ?

[trim matrix]

i have an ItemGrip UScene component attach to the camera in the player character class

and i'm setting the location to that scene component

[signal ibex]

is this an appropriate use of a pure cast?

I usually never use em and I'm just grabbing a value in this case

[versed sun]

what condition do you want met to trigger bClearTime to be true ?

[trim matrix]

it's kind of complicated to explain, but in short i've made it so the bClearTime is passed true when the FireButton (Left mouse button) is released

so the timer is cleared when FireButton is released

[versed sun]

oh, thats each, so you are just setting position while button is pressed, and stop moving it when you release

[trim matrix]

yep

altho there's a small delay (of 0.1 sec) when the FireButton is pressed to check if the player is holding down the button

[fervent temple]

ive been stumped on how to make a system like that

anyone know any good tutorials

[loud cipher]

Hello does anyone know how i can get a finish line working? I have a system where a ai and the player race toward the finish line and i want to be able to tell who gets there first

[loud cipher]

I have no idea how to figure it out though

[trim matrix]

as far as i know, pure just makes it so that the function is called when you need it instead of calling in on exec order. in other words the pure function is called each time a function that needs the output variable is called

[versed sun]

i would go more like this then

[fervent temple]

begin overlap?

[loud cipher]

Yes but how does it know who overlapped first or not

[fervent temple]

so its only 2 at most right

who could cross the line

[signal ibex]

I was taught that pure stuff should only be used for getting values or converting between types, and they should never be responsible for executing big gameplay stuff like spawning or destroying actors

[loud cipher]

4

Players

[trim matrix]

thanks i didn't knew that there was a "Set Timer by Event" node i would use that instead thanks!

[fervent temple]

make a sequence. so for the first time it gets overlapped execute the 1st place code
and then the second time it gets overlapped execute the 2nd person code so on and so forth

[loud cipher]

Ahh okay, how can i create the sequence, is there a node for this?

[trim matrix]

yeah use that only to get values. when you plug this pure function to multiple functions, you'll get different values for each function call as the pure function will be called for each of the functions separately

[versed sun]

hold "s" and click on graph to make a sequence

[clever lion]

im working on a game were the main way to get around is flying but i need help making a in air dive system

[fervent temple]

widgets are just a place holder

maybe u could use a widget to display a first place screen tho

[dawn gazelle]

Put a print string on the pressed. If you get nothing printing on screen, then you're probably not possessing the character that you've put this input action on.

[glass magnet]

nvm i figured it out

[prime stump]

Hi, im still having some issues with my revive system so im wondering if anyone can help, ive done the below and managed to get the desired behaviour that but it only seems to work on the server, if i use the client to revive the downed server player, when the revive is finished it just sets the clients own health to the revived health of 30 and doesn't get the server player up

it seems like when i pass in OtherActor into the OnRevive event its not actually doing the other actor and OnRevive is getting called on itself instead of the downed server player, i have no idea why that is tho lol any ideas?

[odd ember]

maybe ask in #multiplayer ?

[glass magnet]

Am i allowed to send a video example here?

[timber knoll]

Yes

[glass magnet]

my blueprint and the problem

the line trace seems to get longer or rotate depending on location?

also that rotator connected to the division node is supposed to be z not yu

i forgot to change it back after fiddling with things

[timber knoll]

well you are adding a rotated location to your current location

so as your location X, Y, Z components get larger

so will your end result

[glass magnet]

ohh

[timber knoll]

shouldn't you just have a simple vector with X=1

and rotate that, then add it to the actor location

[glass magnet]

also not me just now realizing that multiplying by 1 doesn't do anything at least not in a normal context

[timber knoll]

wait

why is that rotated on the pitch

and then another rotate vector

[formal wren]

Is it possible to get the source object reference when a event is called through a delegate?

[timber knoll]

can actually get rid of most of the top 😂

[glass magnet]

x.x hold on

[glass magnet]

i did this and it works

[timber knoll]

yeah but the pitch rotation makes absolutely no sense 😛

[dawn gazelle]

Pass along a reference to self in the event dispatcher.

[glass magnet]

1 sec

[formal wren]

How can I do that?

[glass magnet]

youre right

x.x

[timber knoll]

working as intended now?

[glass magnet]

yes yes

thank you eezeh

[dawn gazelle]

Same way that you added the "new param" to it.

Just change the variable type to be of your specific object and when calling the dispatcher, feed in a reference to self.

[glass magnet]

but the stuff i had before with the make rotator was working as intended

it was the same before and after i erased it

why is that

[timber knoll]

pitch is up and down

you probably just don't see the difference

no wait lol

you rotated on the pitch for degreePerTrace * traces / -2

which would basically be -180 degrees

[formal wren]

Thank you 🙂

[timber knoll]

which means, your traces were inverted

[glass magnet]

so it was rotated on the Z -180

[timber knoll]

the ones that were supposed to go forward, were going backwards, rotated on the Y

which visually doesn't make a difference 😛 and probably doesn't change a thing about your functionality

[glass magnet]

well i appreciate the help anyways

[dawn gazelle]

Well for one, you're not doing the revive on the server, you're doing it entirely on the client. You call a server RPC (Server_RevivePlayer) which immediately calls a client RPC (Client_RevivePlayer) and this client RPC then calls OnRevive which has all the code for your revive.

[hazy grail]

Anyone here familiar with timelines?

[runic parrot]

Hi! is there any way to get a data table row in a dynamic way?

i want to get a row from a table (both can change)

[gentle urchin]

dont think you can in bp

the table defines the struct used

[prime stump]

Ahh.. thats how the original tutorial i followed had it set up, what would be the best way to set it up to work on both?

[spice lynx]

Define "a dynamic way"

[dawn gazelle]

Not sure, the code you have is a bit hard to follow, but you probably want to run any of your revive code while running on the server (so off of the Server_RevivePlayer) and maybe just do a multicast call for the montage to play.

Normally when you have an ability you'd have Player Input > Server RPC > Server RPC does checks and sets states, Performs Required Action > Multicast any visual results

[mild crystal]

How can i only play a animation once while in that state instead of doing a lot of times with anim notify?

like i made this simple punch 1 state

[icy dragon]

Why not went with montage and anim notify?

[mild crystal]

yes i just dont know how to do it

i know that i need anim notify

but idk how can i use it

[icy dragon]

Make an anim notify in the anim montage asset, and you're off the races from there.

[brave ridge]

so this is my current binding for my HUD for round timer.. its ok for a single preset time but on my lobby menu ive added a timer selection and the array in image is the different times but im stuck on connecting it all together so it works. the basic idea is if the player selects 10 minutes the HUD will show 10 .. same with 15 minutes etc. slowly getting my head round it but guidance would be very much appreciated.

[icy dragon]

Fairly old tutorial, but this goes into using montage and anim notify for attack anims.

[tropic pecan]

Hey there, can I ask anybody who knows a way to select one of the maps first by keys and then values at the end? How I'm attempting to make it work is by selecting one of the keys then choose it's value at the end to transfer to the return node and it seems the way for using the find and get is not working so far.

[dawn gazelle]

Maps have a find node. You feed in the key value, it'll pop out the associated value.

[tropic pecan]

Could you show or explain that to me more?

[tropic pecan]

You do mean this right?

[tropic pecan]

I've tested it and I think it may have worked. Though I may have gotten a unknown error, it seems to be giving the different reactions so far. Thank you for some of the advice.

[loud belfry]

Trying to put these into the render queue. How could I manage an alpha output?

[odd ember]

tender... queue?

[loud belfry]

Hah trying to make it tender to myself 🧘‍♂️

[odd ember]

do you actually have access to the render queue in BP?

because I'm not sure you do

[next vector]

Hello! Hope yall are doing well. I am struggling with unreal engine right now. I am trying to record x, y, and time coordinates into a table. I will attach pictures of the code i have right now. I want the table to be filled with the coordinates as the game is running. But the coordinates are not being put into the table unfortunately. Thank you in advance.

[dawn gazelle]

Tables are read-only at run time.

The closest you can come is by using a Map of Name > Vector and then saving it in a save game if you need it to persist between sessions of your game.

Or sorry, map of Name > Your custom struct

[vocal bobcat]

Hello, Is the blueprint character Event Possessed different from c++ Character::PossessedBy()? I'm noticing calls to Super::PossessedBy() within c++ Character::PossessedBy() trigger my EventPossessed BP event. Since my BP character class inherits from my c++ character class, I was expecting to be able to call Character EventPossessed BP function -> call to parent function -> run c++ Character::PossessedBy but this isn't the order i'm seeing when debugging 🤔

[next vector]

If i want to store the coordinates, should i use an array instead? I would like to have the coordinates so i can import them after the game ends

[lofty ravine]

question is it possible for a render target to work on another level trying to get a dice roller working in a different level and be shown through a widget thanks!

[tawdry surge]

You can only have one persistent level open at a time

[dawn gazelle]

Depends on if you want to access them by index or if you want to be able to look them up by a key/value pair.

[dawn gazelle]

There is the concept of having unreal engine having a separate world and doing something like this, but it can't be done in blueprints alone, there's definite C++ work required there, and I don't really know how to do it myself, just that I know that is how it would be done.

[lofty ravine]

dang that sucks

only work around i know is putting multiple render targets above worlds and make a dice roller

do you have any other ides how i should do a dice roller

[tawdry surge]

You got a link or anything for the multiple "worlds" concept?

[lofty ravine]

not really

do you know any workarounds on the dice roller

[tawdry surge]

I don't understand what you're trying to accomplish.
Dice roller is basically just a random int in range behind the scenes

[lofty ravine]

Yeah

But like 3d object on a widget

That rolls

Like a dice roller on a widget sorry

[tawdry surge]

You could sequencer out the 6 possible rolls and then play the clip according to the random int in range

[lofty ravine]

Hmmm might do that sucky thing is i have to d4-d20

[tawdry surge]

Oh then I'd key out one or two rolls in sequencer and swap materials to make it look like it landed on the proper number

[vocal bobcat]

why not just render it out of view?

[cinder stratus]

Hey, I've been working on a bubble speech feature for actors, just as training, and it actually works pretty well. Problem is that as of now, it's an actor component that has to be added as subcomponent to another actor, is there a more efficient way to do it?

Like I have an Actor Bubble component that dynamically creates a Chat Bubble when I go near the actor it's inserted in

[tawdry surge]

Way heavier performance wise and not typically good to use physics for something like rolling dice

@cinder stratus add the component to your base character class and all children will inherit it

[cinder stratus]

Yep, but like, is this a good way to do it or there's a better way?

I'm learning, that's why I'm asking

Also I'd probably want only NPCs to inherit

[tawdry surge]

Then you can apply it to your base npc class.
But thats about the most efficient way

Add it once and everyone who needs it has it

[cinder stratus]

Okay, thanks!

[dusk dust]

how can i have each section contain the same scaling when it comes to calculating height?

[neat stratus]

Super noob here. Can anyone point me into the right direction of maybe a youtube video that shows how to create an in-game button to toggle on and off static meshes for an archviz project? I cant find anything on it.

[bleak swift]

Doe's anyone know why my Game when running on a client won't Control a Pawn or Display UI

Completely new Project just with new Widget's

[dawn gazelle]

Did you change the default game mode or game state?

[bleak swift]

Nope

Work's fine when running on Server

[dawn gazelle]

What is the netmode set to?

[bleak swift]

I've tried all 3

Standalone works fine
Listen Server only let's the Server see the UI and Control a Pawn
Play As Client doesn't allow any Instance to Control a Pawn or see the UI

[dawn gazelle]

Are the pawns still spawning for any clients?

(other than the listen server)

[bleak swift]

I don't know how I could tell

But I don't think so

[dawn gazelle]

Usually when you do Play As Client you'd see your pawn in front of you, no?

[bleak swift]

No Pawn just the camera placed below the floor

[dawn gazelle]

Can you show what your world settings look like:

[dawn gazelle]

How many player starts do you have placed in the level?

[bleak swift]

5 Of Them

[gray chasm]

This seems like something obvious, and I'm missing something. If I want a character to rotate to a particular direction when you click with the mouse, but also set orient rotation to movement to true, how do you do it? Just setting the actor rotation sucks because it 'teleports' the character to the rotation, instead of smoothly rotating like Add Movement Input does...

Is there something like Add Movement Input you can use to smoothly rotation to a direction without actually moving?

[tawdry surge]

VInterp or lerp and timeline

[dawn gazelle]

My last basic guess may be that you don't have ThirdPersonCharacter set to replicate.

Though I'm doubting that is the problem either as that doesn't change anything on my end....

[tulip mason]

When you click? Like top down mouse clicker? If you click to move with orient to movement, wouldn't that just happen?

Or like they would just turn to the direction you clicked? Cause you'd need some sort of turning timer thing that finterps to the rotation or something. But yeah just setting actor rotation is basically a teleport thing.

[gray chasm]

No, because I'm not using mouse to move

Only to shoot

Yeah, a lerp with an interrupt appears to be the best solution.

I was hoping like a scale factor of 0 or something like that would work on Add Movement Input... but no.

[dusk dust]

anyone know the answer to this? let me know if you need more info

[trim matrix]

I no understand that

also, I have a reference built to it tho

[dawn gazelle]

GameStateRef no set

[trim matrix]

but I have a reference tho

[dawn gazelle]

Do you actually get the gamestate and cast to it or something?

Then set that value in the GameStateRef variable?

[trim matrix]

that is the gamestate reference

[dawn gazelle]

And that's happening after you've called those two functions

[trim matrix]

wait what?

so I need it before?

[dawn gazelle]

Yep, hook it up to 1

er 0 sorry

[trim matrix]

yay

my man

or woman

thank you

[tulip mason]

Would probably help if you explain the context of your game to figure out what you're trying to accomplish, cause hell if I know. First person? 3rd person? Top down? Sidescroller?

A lerp works, but then you need an alpha, which would still require something to drive it so the alpha changes.

I guess this is what an aiming state is for in situations like that so the rotation is more finely tuned to your control rotation.

But shit for all I know it's a hockey game.

[dusk ember]

i was curious; can i use curves for something like damage?

[dawn gazelle]

Yep

[dusk dust]

Can someone help me with this?

please let me know if more information is needed

[midnight wedge]

Is there any way to promote these values in a timeline to a variable? I'm trying to create a smooth zoom in and out function, but the starting point differs depending on whether or not the player is aiming so I want the starting float to just be the current arm length and then automatically blend to the correct one

[forest timber]

Does anyone know why sometimes code just...stops working? I'll load up a project and some things stopped working properly

[icy dragon]

You can use Map Range Clamped and have the timeline float go from 0.0 to 1.0.
Admittedly it's kinda hacky but it should work.

[midnight wedge]

hey, any help is appreciated!

I was also wondering if there was a way to use finterp, but my experimentation with it was meh

granted a refusal to use event tick prolly doesnt help

[icy dragon]

Event Tick is not as bad as some people want you to believe.
It's just that one can abuse it and put unreasonable instructions that took up lots of frame time, like Get All Actors of Class.

[midnight wedge]

I know, but for my purposes I don't think its neccesary

[pulsar rampart]

Guys I want to do something and i need help so i want when a player join a server it says "Player Name" Joined the game So anyone know how can be that possible or send me video that illustrate this Thanks 🙂

[gentle urchin]

For a smooth zoom, tick is more or less mandatory, or atleast something very close to tick

Its very visual animation so if anything is allowed to tick, i'd say this is one of those things

[midnight wedge]

I found a lerp and timeline worked well

[gentle urchin]

Timeline is tick 🤫😄

[midnight wedge]

True but its not constant so Im fine with it

Event tick is always firing

[gentle urchin]

Yeah timeline handles gating internally so its easier to use

[loud belfry]

No it doesn’t seem like

[pine pivot]

Hello,
I'm making a minimap and what I'm trying to do is to hide the minimap when I press "M" so that it shows a big map instead. I have no problem showing the big map but my problem is that I can't hide the minimap in runtime (set visibility to hidden). Selecting the hidden property in the widget itself before playing works, so it has something to do in runtime

do you guys know how to fix that?

maybe a setting to tick

Thx

[gentle urchin]

Probably not on tick🤷‍♂️

[pine pivot]

I mean to tick true of false

[gentle urchin]

Seems like ur nesting is suboptimal

You could try a widget switcher instead

[pine pivot]

yes

but the event there was just to test

[gentle urchin]

Right but toggling visibility on the parent surely affects the child

[pine pivot]

i could not call the hide feature from my character bp so I tried with events

it seems like the whole widget (even the parent) can't be hidden

[gentle urchin]

Surely it can

I would consider nesting it in a widget switcher tho

As they seem to be mutually exclusive

The map vs minimap and player ui elements

[pine pivot]

I'm gonna look into that thx

[spark steppe]

beside of that, rightclick you UI Map variable, and select "convert to validated get"

and replace those ugly isvalid nodes with that

[maiden wadi]

Seeing a single blueprint variable being drug to multiple nodes bugs me.

[gentle urchin]

Surely adds alot of spaghetti that could easily be avoided^^

[maiden wadi]

Ever since I started writing C++, I tend to stack my blueprint nodes together as much as possible. Much easier to read through and not have to backtrack through reroutes and such.

[gentle urchin]

Same 😂 i also tend to make c++ functions for almost anythimg so bps stays nice and readable

Just a bunch of function calls

[maiden wadi]

Ton of my single input stuff looks just like this. Targets on top, function call, argument on the bottom. So much easier to read through when you have ten settings to do in a single execution line.

[spark steppe]

yea but your order of nodes on the bottom bugs me 😄

[candid nest]

Hey i have an actor which spawn when game begin i want to spawn some static mesh with that actor but random meshes as there are many and with perfect transform how can i do that any suggestions

[maiden wadi]

Not sure what you mean by with perfect transform?

[candid nest]

Like i can change that location and scale in future if i want to change

[icy dragon]

I can't even read it without punctuation marks, lol.

[spark steppe]

where did you add them? because i still have a hard time grasping it

Hey i have an actor, which spawn when game begin. i want to spawn some static mesh with that actor, but random meshes, as there are many and with perfect transform. how can i do that? any suggestions?

that's the best i came up with, but still...

[maiden wadi]

I think that an example might be easier to help with. Unsure of your end goal intentions with this. Like, spawning a mesh in an actor is easy, add a static mesh component and set it's mesh to the randomized one. Save the pointer and you can change it's local location to that actor or scale it. Have a feeling that might not quite be what you're after though?

[candid nest]

Actually i am making a endless runner in which i am able to spawn the floor but can't able to spawn side of world so i am thinking if i can spawn that in an easy way

[spark steppe]

are you using google translate?

[candid nest]

No

[spark steppe]

maybe you should...

[candid nest]

😂

[spark steppe]

yea sorry, but it's hard to understand what your actual problem is

[candid nest]

Did u play any endless runner game till now

[spark steppe]

does super mario count?

[maiden wadi]

Stuck on side of world. Not sure if meshes directly to the side of the running track or mountains in the distance.

[candid nest]

I made a path on which my player will run but i want that the side world also should be spawn which is not spawning so far

Side world is static mesh

[maiden wadi]

Sounds like you just need to reference where you're spawning floors, and use their transforms to spawn meshes to the side of the track.

[candid nest]

Yeah quit a bit like that only

[gentle urchin]

Id switch them to minimize crossing wires 🙅‍♂️

[maiden wadi]

Personally. I'd consider going with a prefrab route. Make an actor that can be spawned along the track and that one actor picks it's own track obstacles, floor, and side meshes. Much easier spawning code.

[candid nest]

Yeah i want to that only but i am not able to do that quite noob

[icy dragon]

Show us what you have got so far.

[gentle urchin]

Seeing the code is more helpfull.. 😅

And seeing something of the desited outcome can also help, if its hard to put words on it

E.g. does any game have what you want? If so, a screenshot or smth would be nice

[halcyon laurel]

good mornin , i am stuck trying to possess another character with another game mode and controller , i want to make it through a button in a widget its function is to possess to the other character , i hope some one can help through this , and thx in general

[gentle urchin]

With another game mode ?

As in world / level game mode ?

[candid nest]

Yes subway surfer have this i want exactly like that

[gentle urchin]

Walls?

[halcyon laurel]

yes with another functionality and inputs too

[candid nest]

Ye s

As u can see i have the middle path i want the side world i am not able to do that

Like house tree i make them into a singal mesh and i have 20 mesh like that i want random 20 mesh spawn sideways

[tawdry surge]

@halcyon laurel you can't change game modes without loading a new persistent level. If you're other character is set as default pawn for that game mode, you'll possess it automatically

[trim matrix]

pretty sure there are ton of tuts online on this very topic, maybe start from there? and if you're stuck on anything you can always come here and ask us

[maiden wadi]

He's looking for how to create the non gameplay visuals on the side at runtime dynamically.

[candid nest]

@maiden wadi yeah

[trim matrix]

yeah this is a great start, first make a system that spawns meshes on the sides, randomizing them is easy

[candid nest]

@trim matrix but i will surely look for this

@trim matrix yeah i thought of watching this but i think it will not be helpful but i will surely watch this

[trim matrix]

for an endless runner, you need to have modular meshes, spawning them and randomizing them on runtime is pretty straight forward

[candid nest]

Yeah

My project will have signs I want to translate in several languages and I want it to be in a "subtitle" style as seen in the above picture. I'd appreciate any advice on the topic, maybe even a tutorial?

[tawdry surge]

You'd just have the sign pass it's text to a widget when in range.
Localization would pry require a datatable or some sorta list of the various versions of the text

[viscid python]

Thank you for taking the time to answer! I already use datatables for translations but didn't know how best to approach the close caption issue, thanks for the advice 🙂

[trim matrix]

does "Set Timer By Event" not work with 0 as timer argument?

this is not firing the function

[trim matrix]

ahhh

[gentle nebula]

I'm trying to get a mouse click event on a text world widget, any advice on how to achieve that?

[tawdry surge]

If you mean you wanna click on a 3d widget placed in the level, you need a widget interaction component on the character or controller

[gentle nebula]

i have that, and can interact with it, my problem is that the text umg only got these two events

Is it possible to add a mouse event to it?

So i'm thinking about declaring an event on the c++ files

[tawdry surge]

Not to the widget itself. You add it to the character or controller and trace to the widget and do what you want from there

[gentle nebula]

for some reason, the hitresult stop working when i'm over the widget

maybe because i've set it to capture input ?

The world widget didn't worked without it

[tawdry surge]

Can you show your code? It should just be a trace from the mouse to world space and then if it hits the widget, you fire whatever event inside it..

[gentle nebula]

I'll screenshot it

so i have these two world widgets

the one from the left

with this one i cannot interact with the text

the one from the right, have "recieve hardware Input" enables, it recieve text properly, but when i put the mouse over it, there is not red dot

didn't found another way to allow the text to recieve input

[formal dagger]

hey guys, i've got a question. I would like to let the player choose a folder path where his/her music is located to be played IG (like in sims or space colony), is it doable in BP ? Or do I have to pre-create a folder where to copy the musics ?

[spark steppe]

@formal dagger for file access this might work: https://www.unrealengine.com/marketplace/en-US/product/blueprint-file-sdk

but i dont know about the audio part

[sly shore]

https://www.unrealengine.com/marketplace/en-US/product/runtime-audio-importer this maybe?

[gentle urchin]

Wouldnt it be ok to just let the user play their audio from outside the game ?

Implementations tend to be limited anyways..

[formal dagger]

the one i use, yes ^^

[formal dagger]

thx i'll try

[pine trellis]

I made a blueprint and added a static mesh and some capsule collisions to it but when I stretch out the mesh in the world, the capsule collisions dont get stretched out with the mesh

I tried to attach to both the default scene root and static mesh with same result

[versed sun]

try dragging you capsules onto your static meshhttps://www.screencast.com/t/6g7hX0YQdC

[pine trellis]

tried that still doesnt stretch them out

[maiden wadi]

This isn't really a use case for collision objects though. This kind of thing is something you'd export with the mesh.

[gentle nebula]

Anyone know why would a world widget won't recieve input ?(i have widget interaction component) For example, the buttons does receive hover events, but not click events, and i can't interact at all with texts.

[pine trellis]

@maiden wadi but I need to test the collisions

[odd ember]

nice alliteration

[odd ember]

something about having to enable mouse click events in the player controller?

[gentle nebula]

maybe? i'll check

[maiden wadi]

WidgetComponent itself needs to block real collision channels for the WidgetInteraction to hit it, sounds like you have that. Widgetitself still needs to be hittesable. Sounds like that's fine with the hover. There are also issues with the interaction component requiring specific IDs set up for multiplayer stuff.

[gentle nebula]

Any idea how do i deal with that?

[gentle nebula]

seems ok i think?

[maiden wadi]

Not sure what you mean by this. Collision components are meant to be simple shapes for simple gameplay use. If you need more complex collisions for a static mesh, either generate it on the mesh in the static mesh viewer, or import it with the mesh itself.

[versed sun]

do none of them stretch , or they stretch incorrectly ?

do you need different collisions per area of the box or are you trying to make one collision that covers all edges ?

[runic parrot]

Hi! does anyone know if "while loop" node condition is evaluated first of after completion? (the first run checks the condition?)

[maiden wadi]

@gentle nebula Player controller settings are irrelevant to widget interaction. Chances are you're not using the Interaction's interaction functions.

If you're not, you're looking for PressPointerKey, and ReleasePointerKey functions.

[gentle nebula]

Are these necessary?

[maiden wadi]

That's just how you use the interaction component.

[gentle nebula]

My bad.

Does it support full keyboard interaction? for example if i set it up currectly, would i be able to ctrl+C inside in a text umg?

[maiden wadi]

Uncertain. I've never went quite that far with it. I've only used it to make basic interactable widgets for actors like a hologram display.

[gentle nebula]

I appreciate all the information so far, thanks!

[mild crystal]

how can i check if in the moment im not clicking in any button?

[versed sun]

maybe

[mild crystal]

i cannot found that function can you tell me where you found it? @versed sun

[versed sun]

you need a player controller , or turn off Context Sensitive

[gritty elm]

GetPlayerController and then from player controller reference, search for IsInputKeyDown

[mild crystal]

Btw can i set a boolean inside a state in anim bp?

[gritty elm]

Yes. on EventUpdateAnimation, store into bool and then get variable inside state machine

[mild crystal]

can you do a exemple pls @gritty elm

[gritty elm]

https://docs.unrealengine.com/4.27/Images/AnimatingObjects/SkeletalMeshAnimation/NodeReference/Events/event_updateanim.jpg

Did you ever used this event?

[fresh magnet]

Hey guys I am a bit in a pickle reason being that I am trying to make a material instance that can be applied on an object that the transform can be manipulated in any way the material will still look the same, I manage to use a world position_with_scale node and it works semi-successfully because as I rotate the object the material instance does not rotate with it 😦 any fixes or nodes I should try?

[mild crystal]

and how do i say to a animation start on a certain point. I only wanna play last 20 frames from my animation. how do i do that?

[tawdry surge]

I don't remember what it's called off the top of my head but there is a way to scale the UV's with the object size.
Iirc they use it on the automotive materials provided by epic

[fresh magnet]

ah thanks will take a look

[maiden wadi]

Basic UMG needs more setting options for some widgets. :/ Kind of bugs me that progressbar doesn't have a set from timer function. But whatever. Wrote it into my own wrapper.

[timber knoll]

You are asking so many different simple questions, I would advise to do some more self learning and look up stuff on the internet.
People aren't going to keep helping you this way, as it feels a little low effort from your side. Just being honest, don't want to be rude.

It's okay to come here ask for advice or something that you can't figure out yourself,
but you should generally have already tried something out, we aren't google 🙂

[odd ember]

probably a good question for #animation

[fresh magnet]

Hey @tawdry surge are you referring to this

[tawdry surge]

Probably but it's been years

It's was part of an epic online learning course about materials.
The one leather with eyelets material has it for sure

[fresh magnet]

Ooo Might know where to find it, yet again thanks for the help

[odd ember]

this is probably more of a material question than BP question. you can handle it entirely within the material. I'd ask in #graphics on how

[fresh magnet]

Ok sorry

[versed sun]

I'm thinking of remaking a large project that I have been working on for over a year. Everything works fine with no major bugs but I know there is a better way of doing some tasks. Would someone with cpp and Blueprint knowledge be able to video call with me so can show them how I did things and pick their brain for any improvements? I hope it would take less than 30 min and could be done now or later.

[odd ember]

oof

sounds like something you really want to pay someone to do

[versed sun]

i was thinking of that

thought I would ask first

[mild moon]

Hi guys how can I implement the different speed based on the surface type?

[odd ember]

physics material afaik

[mild moon]

I tried

[odd ember]

welp

[mild moon]

But i dont see any improvments

[odd ember]

have you tried a tutorial on them?

[mild moon]

I created the surface type in the project settings and then i created a physics material

After in the material of the surface i add the physics material

[odd ember]

you can always try and break down some of the systems you're using. I'm happy enough to assist here but I'm not up for video calling

[odd ember]

@mild moon

[mild moon]

I can't found a tutorial based on it

[odd ember]

🤔

https://www.youtube.com/watch?v=_QO4rJoBsWc

literally second result on a google search

first results were the docs

[mild moon]

I was serching the wrong key name

Thanks

[versed sun]

The main thing is: I have a ton of BP structs that are being written and saved to a save game, and I believe that's bad ?

[odd ember]

if it works it's not bad. but BP structs are copies and are generally meant to be read from, not written to

[versed sun]

how would I know if it DOSN'T work? I havn't had any problems yet

[odd ember]

your values are nulled out

[versed sun]

ok, so far so good

[odd ember]

it could fail silently in that the project works without issues, but certain things just don't load

[waxen gull]

This Is My LevelBlueprint

[odd ember]

cool

was there a question?

[waxen gull]

I have no World composition activated

yea

why are there 4 levels in my game ?

[odd ember]

where do you see 4 levels?

[waxen gull]

nowhere

have only one

[odd ember]

well I don't see them either

so how did you come to the conclusion that there are 4 levels in your game?

[waxen gull]

look at first screenshot

the node setup

can only print once

[odd ember]

that doesn't mean there are 4 levels in your game

[waxen gull]

it does

[odd ember]

if there were, you wouldn't see it print 4 times, you'd not see it print for the other levels

[waxen gull]

cause i add 1 to a variable repeat

sure

but begin play is fired 4 times

and it does not use updated variables

[odd ember]

spoopy

[waxen gull]

you have any idea why it is that way ?

[odd ember]

not on top of my head. if you're switching game modes maybe?

but equally I can tell you there aren't 4 different levels

[fervent jolt]

Hey, whats this type of node called? the purpley sort of general node type? Thanks

[odd ember]

function

[fervent jolt]

Thanks @odd ember

[waxen gull]

right on screen there is a function drop down you can override it

so i have only one gamemode

and its not changing anywhere

[odd ember]

the only other thing it could be is that the level is loaded 4 times somewhere else

so if you're loading the level somewhere, check that code

[waxen gull]

i have pretty basic level setup

nothing with changing any levels blueprints etc.

[odd ember]

I don't know what "basic" means in this case

if you open levels anywhere else

that's likely where there's an issue

[waxen gull]

i am only loading in one level

at start

and i did not setup anything else with loading levels ...

[odd ember]

is this PIE?

[waxen gull]

PIE?

[odd ember]

play in editor

[waxen gull]

happens in Play in Editor and Standalone Game

Is there an Event that is fired when changing Level ?

or loading level again ?

[odd ember]

BeginPlay

[waxen gull]

hm

When loading in a New level all other Events should be Stopped right ?

[odd ember]

how do you mean?

[waxen gull]

Like

[odd ember]

like what?

[waxen gull]

Added this

so when loading in a new level

this even should fire?

[odd ember]

yes

[odd ember]

if you load that particular level

with that particular logic

[waxen gull]

you said there could not be several levels at once

[odd ember]

I didn't say that

I said that if you had several levels you wouldn't get this behavior

[odd ember]

that's on tick

[waxen gull]

yea

[odd ember]

that gets updated every frame

[waxen gull]

but each number is there 4 times

should only be printed once

[odd ember]

do you have any level streaming volumes?

[waxen gull]

no in world Outliner

[odd ember]

hard to say then. maybe if you had four separate instances of the same level loaded somewhere, like 1 server + 3 clients

[waxen gull]

ohh

4 several levels

but why ?

[odd ember]

.

[gentle nebula]

I'm trying to make Widget interaction work, but after setting press pointer key, nothing seem to happened

[waxen gull]

can't be several instances

[odd ember]

well you've just proven that it is

[waxen gull]

https://cdn.discordapp.com/attachments/221798862938046464/942486730450301008/unknown.png

4 times same game instance

[odd ember]

there's 4 separate instances here

[odd ember]

doesn't matter?

[waxen gull]

4 different levels tough

[odd ember]

the same game instance can run 4 separate instances of the same level

[waxen gull]

ok

[odd ember]

don't conflate things

[waxen gull]

do you know where levels are created ?

[odd ember]

.

[dawn gazelle]

Well when a momma level and a pappa level love each other very much....

[waxen gull]

the game is not meant to be multiplayer

https://docs.unrealengine.com/4.27/Images/InteractiveExperiences/Framework/GameFlow/GameFlowChart.png

[odd ember]

can you screenshot your play settings?

[mild crystal]

can i have multiple event tick? how do i create a event tick

[odd ember]

no

1 event tick per actor/component

you can create timers using delta time

that do the same

[mild crystal]

ah ok

[waxen gull]

you can do this

so since i have several levels on same Game Instance, these Levels must be created somewhere

[odd ember]

.

[dawn gazelle]

Just a silly question, but have you tried restarting the editor?

[waxen gull]

This ?

[odd ember]

looks like there's only 1 client and it's single process, so that checks out

maybe try the restart editor advice

[zealous meteor]

Hi! I have trouble at replacing tick event with something else in order to optimize the performance

[waxen gull]

restarted my Computer, Problem persists

[odd ember]

show code

[zealous meteor]

Yes, Im making the screenshots now

[odd ember]

hard to say what's wrong then. if you're not having any code that has to do with opening levels anywhere then I'm drawing a blank

[waxen gull]

can i search for code somehow ?

i would have a look where levels are created

[zealous meteor]

The order if from down to top

[odd ember]

if you haven't made the logic yourself and you're the only one working on the project, there isn't going to be specific level loading code

[zealous meteor]

So basically what I want it to do is when the player grabs the interactable object which is called pill, a countdown of 10 secs starts

[waxen gull]

just created a new blank level

dont have the problem there

@zealous meteor You can bind a Event on Pickup

[zealous meteor]

It normally works with event tick but the problem is I want to add a prompt when the player looks at the interactable object

[zealous meteor]

Can you give more details?

[waxen gull]

thats pretty rough:

not binding event tough

should work too

[iron bone]

Hey everyone, I'm trying to make an enemy in an auto-running game and wondering what's the best way to make the enemy object follow and float around the player character as they run? I've tried attaching the actor to my player but it's not working as I had hoped

[dawn gazelle]

I saw your question so I wanted to answer it: Set the interp speed to how fast you want it to go.

[mild crystal]

thx a lot mate

@dawn gazelle like this?

[waxen gull]

@odd ember If the Game Instance that is running on my Computer runs 4 times the same level would make me thing that it is running everything 4 times...

begin play function on other actors only outputs me only once hello by print string

why is it not running everything 4 times ?

[dawn gazelle]

Using a delay on tick is probably not the best way.... If you want something to go up every 0.1 seconds, you may as well use a timer and the input controls the timer. This assumes the value starts at 0, the increment will make it go up to 10, then 1 back up to 10 again.

[mild crystal]

because i want create something that will check how many times i pressed left mouse button in 1sec but after that sec it will back to 0

[odd ember]

there was only 1 game instance

[waxen gull]

so the levels are not holding the actors they include ?

[odd ember]

they are

but one game instance can have multiple levels

[waxen gull]

i have 4 times the same level in my game instance

[odd ember]

no

your level gets loaded 4 times

[waxen gull]

no

[odd ember]

yes

you're conflating things

all you know is that the same level gets BeginPlay called 4 times

[waxen gull]

tick function is fired 4 times every tick too

so there must be 4 levels running at the same time

or do the other levels are not rendered ?

[atomic iris]

Quick question, how would I spawn an actor without changing its scale?

[odd ember]

exactly what I said here

so yes you have 4 instances of the same level loaded for whatever reason

[hybrid ether]

Best way to make progress bar 0% to 100% smooth with float time (crafting time)?

[waxen gull]

so my CPU makes 4times more calculations than needed ?

[dawn gazelle]

That's completely different than the problem you posited XD Here's something that can count the number of clicks in one second.

[odd ember]

this has nothing to do with your CPU. why are you talking about these things? focus on the issue, not everything else

[mild crystal]

thanls

thanks

[waxen gull]

lets say i would be fine with that issue, and fix it by not using the Levelblueprint, i am unsure if since there are 3 other levels if they get calculated too

bad english

[odd ember]

whether you use the level blueprint or not

you have an issue where 4 of the same levels get loaded

[waxen gull]

which is a problem for performance ?

[odd ember]

potentially? I'd say consistency in terms of gameplay is probably a bigger issue than performance

but yes performance as well

[waxen gull]

well ... that will be a fun issue

[odd ember]

if you don't have this issue with other levels

move your actors over to a new level and start fresh

that's the best advice I can give you

I don't know your project

[waxen gull]

yea

[odd ember]

I don't know what caused your issue

so I can't tell you how to fix it

[waxen gull]

lets hope that the issue won't come back

[maiden wadi]

I have a vague memory of someone else having that issue with level blueprints at some point. Two beginplays running and such. Only fix was a new level.

[odd ember]

if it does you can backtrack and figure out what's wrong based on what you added to e.g. the level blueprint

[waxen gull]

@maiden wadi had a quick look on that one too

@odd ember yea thing i will do that

Can i drag and drop actors from outliner from one editor to another ?

[odd ember]

if you open up the levels window

you can create a new level as a sublevel, select all actors, move them to the new sublevel, and remove the sublevel

your sublevel stays as persistent data, but you can run it separately

just remember to save once all the actors have been moved

[waxen gull]

copy pasted from one editor to another

[odd ember]

okay well if you prefer it the hard way be my guest

[atomic iris]

I added a projectile movement component but it doesn't seem to do anything, even the gravity and initial speed gets ignored. What am I doing wrong?

[waxen gull]

@peak wedge

[atomic iris]

Wait what, the movement works I add a scene layer above it ... but the rotation doesnt

[lofty ravine]

ok so when I spawn an object into my landscape it just never stops and it keeps on moving

just never stops

[echo salmon]

This nodes in the picture is to torque the ball and move it to the direction that the camera is facing ( given the Controller ) how the get right vector helps to move to the controller direction ?

[weak zealot]

I'm having a really hard time understanding the question

[echo salmon]

Why do we use the controller right vector to move the ball at the camera direction ?

[lofty ravine]

when I spawn in a dice it keeps sliding off the landscape, and the velocity never stops is there a way I can stop this I tried putting up the friction

[dawn gazelle]

Imagine the red axis in this image is the forward vector of the sphere. If you wanted it to spin in the forward direction, you would need to spin it on the green axis.

That means you need to apply torque on the right axis.

[echo salmon]

Thank you for your answer iam try to comprehend it in my mind.

[dawn gazelle]

If you were to apply torque on the forward vector (again, being the red axis) then it would being turning the sphere left or right

[echo salmon]

true

I now got it

Thank you so much

my brain couldnt understand why lol

[mortal cradle]

Back then I made an ability system and I put all of it's functionality on the player character bp, it works very well and I'm wondering if in such situation there is any reason for me to now put most of it into the actor component (since this is how I see lots of people do it) or should I keep it in player character bp?

[echo salmon]

@dawn gazelle ty bro

[dawn gazelle]

It depends on whether or not you're going to have classes that would need that functionality that won't inherit from the class that contains that functionality. If you're planning on using that ability system with child classes of the one that has it, then you don't need to move it into a component.

[median monolith]

Hello. I'm struggling with a problem with ue4 that is making me crazy.
Simplifying the matter: let's say I have an actor with a light that turns on when it finds actors of the same class in the level. To see them right (lit/unlit) in the editor, I look for other actors within the construction script.
So I put actor A in a level, that starts unlit. Then I put actor B, that finds A, so it turns on and tells A to turn on too.
The problem appears when I delete A from the level, because B doesn't know that A no longer exists.
I've tried to use the OnDestroy event, but it doesn't fire on editor. ¿Any idea to deal with that? 💡

[trim matrix]

Left and right orc/troll are trying to get to the middle and they jitter as a result. Does anyone know how to fix this issue? What could be the problem?

[dawn gazelle]

They're all trying to reach the same destination and are colliding.

[gentle urchin]

Not much you can react to there. You can check the next time construction script on A runs if B still exist but beyond that... not much.. c++ might help here.. some odd scenario if im being honest but only you know your usecase

[trim matrix]

any way to fix this? make collision more smooth

[high sapphire]

What I ended up doing was just creating separate inventories for the different categories. However, the lists for the weapon/armor/etc. inventories don't show the items even though it's the same logic as with the consumable items. I'm not entirely sure why.
The consumable items also don't show the icons/names/amounts/etc
Not sure where I'm going wrong, I'll attach screenshots of my Blueprints in a sec (shame I can't make a thread so my screenshots don't clutter up the chat)

[median monolith]

And... do you know if there is a way to force the whole level to run their construction scripts. I mean manually, from a menu of the editor or something.

[gentle urchin]

You need some crowd manager , or bigger acceptance radius, or abort on collision

[high sapphire]

This is the Blueprint for the consumable item list. The other lists are the same as this one, but checking a different inventory of the player rather than "use inv".

[gentle urchin]

You can make editor utility functions

Or use a blutility with some getallactorsofclass , calling the same function as constructions cript does

[high sapphire]

This is the Blueprint for the widget that the consumable item list spawns

[high sapphire]

This is a snippet of the Add to Inv function (it's not done yet because I'm first making sure I set up the weapons part before copying it over to the rest)

[high sapphire]

This is off of the consumable items inventory. The weapon inventory one is exactly the same

[high sapphire]

After picking up three consumable items and three weapons

[dawn gazelle]

You're adding to your inventory, yet you're only doing so if the inventory already contains that item.

?

[median monolith]

Thank you, I'll try with that.

[fierce stump]

Got most of the health system set up, but there's the issue of everything being super accurate. Is there a way to change anything in the damage instigator or the health counter widget so it's rounded up to the closest decibel?

[mortal cradle]

@dawn gazelle Not sure if I understand, I do have classes that need abilities functionality in a way but those are AI's and widgets, AI is responding to the abilities but not really using them. And widgets store all the data, I think you meant that if I ie. had an AI that could use the same ability as the player then component is a much better way?

[dawn gazelle]

As in, if you're only using one base master "character" class that all your characters will use, including AI, then it can remain on the character as you would still be able to access the functionality of it in all subclasses of your master class.
If you're not intending on doing that, and have character classes that are not inheriting from the class that has the functionality, then you should put it in a component as you can then add that functionality to any other classes that need it.

Pick your poison

[dawn gazelle]

The logic you have doesn't really make a lot of sense to me. You're incrementing the value of an object if it exists in the array but at the end of the loop you're adding the item to the array again.
You probably want a function that validates if the item is in the inventory already and returns the index in the array that has the item so you can increment the value at that position only, and if it's not in the inventory, then you add it.

That means you'd likely need to use a Set Array Elem node that lets you directly set what is in the array at a certain index.

Based on what I'm seeing here you're also building yourself into a trap... Using arrays stuck into your player is not the way to manage multiple inventories. You're going to be redoing the same code over and over again for each different inventory you have - there is little point to that and makes it even harder to maintain. Create an Inventory component (a blueprint that inherits from Actor Component) - this should contain 1 array for the contents of said inventory, and all functions related to how that inventory operates (adding items, removing items, etc.). You then attach this component to your player controller or character, or whatever actor you wish to have an inventory. If you want to use multiple inventories on an actor to keep things separate, that's fine as well, but add multiple components to the actor rather than trying to add multiple arrays that you end up having to manage.

When you're creating UI to represent said inventories, then you just need to feed in the component into the main widget that represents the inventory. That widget should then be able to read the inventory, and create any widgets that represent the items in the inventory.

If you end up having multiple inventory components, then when picking up the item, you need to decide which inventory component actually receives the item, and call the "add item" function of that particular component.

The flow would then look something like:
Player Moves Overtop of Item > Player reads item data from Item > Determines Item has tag "Item.Weapon" > Player grabs its "Weapon Inventory Component" and calls "Add Item" function

[sand bloom]

is there a good way to stop characters from falling off ledges in the character movement component? I know you can make your capsule super thin but that messes with other collisions

[hazy grail]

@fierce stump you mean decimal. Yes to round up there is a ceiling node for rounding down it's called floor.

[sand bloom]

adjusting ledge check doesn't help

It's like the capsule is glued to ledges, I want it to slide off

[odd ember]

make your edges sharp enough for a falloff

[hazy grail]

@sand bloom have a line trace in front of the character. If the line trace traces further than a certain distance it doesn't allow the character to move forward anymore.

[sand bloom]

What do you mean? It can't get much sharper than a cube right

[sand bloom]

hmm interesting idea, although I don't need it to stop but to fall, but I could push it into the direction to make it fall maybe

If I can't find a better way i'll have to try a linetrace thanks

[odd ember]

if you slope it downwards it'll slide

but you would have to do that for every edge

[sand bloom]

Oh yeah I don't think that'll work for me but yeah I suppose that could help

Appreciate you thinking with me

[vague dome]

Im making a 3d widget for my crosshair, is there a easy way to have a worldspace widget (so that its masked by objects) that has a fixed screensize?

basically i want the widget to be hidden if it goes behind objects but also stays the same size based on distance

[sand bloom]

Got it to work ok with a linetrace thanks water 🙂

[high sapphire]

So would that look something like this, for the Add function in the component?

[dawn gazelle]

A bit more complex than that.

[dawn gazelle]

Also, your array in your inventory does not need to contain all the data about the items. Just the item ID and the quantity

[foggy dew]

Not sure if this counts as a physics or BP question, but
Anyone know a good way to go about detecting overlaps for an expanding collision cylinder? (for a quickly expanding radar pulse)
As I understand it, collisions meshes don't generate overlaps when rescaled during runtime
I can definitely find some sort of spaghetti solution to this, but want to make sure I'm not missing some obvious solution

[icy dragon]

If you don't mind some inaccuracies, you can step through different size of sphere collisions.

[maiden wadi]

If they don't call overlaps when rescaling, you could set it's location again to the same location. Not sure if it's optimized to ignore that.

[foggy dew]

Thanks! Yeah, I'm probably gonna go for the step every few frames-solution, accuracy isn't that important
unless that set location trick works

[fierce stump]

I don't know if I've set things up incorrectly in either the weapon base or NPC base blueprint, but the test NPC I created refuses to take damage

[iron bone]

Is there a way to make an actor move towards a player without having to use ai? It's just a static mesh and not a character

[foggy dew]

Does the Any Damage event here run? Probably easier to solve if you can figure out exactly where it's breaking
Try putting a print string right after the event AnyDamage?

[foggy dew]

Probably the simplest way would be to make it find a player with something like GetActorOfClass, save it as a variable, and move the actor towards the saved actors location in event tick?
Not fancy but should do the trick :P

[iron bone]

Thanks! Which node would I use to move the actor in event tick?

[icy dragon]

Get Player Character -> save the reference to a variable

VInterp To on Event Tick -> Target is player character's location

[iron bone]

thank you!

will try both

[foggy dew]

(Don't need to try mine, that solution is cleaner, forgot about Get Player Character)

[icy dragon]

Don't use Get Actor of Class. It's much heavier than Get Player Character (or Get Player Pawn)

[trim matrix]

wait

what if you need to make a reference to something?

[fierce stump]

Doesn't run at all. Tried putting in the Print String, still no result.

[trim matrix]

or are you just saying in comparison?

[fierce stump]

I think it might be something in the weapon base blueprint:

[foggy dew]

Is the Line Trace by Channel hitting what it's supposed to be hitting?
Other than that, this does seem like it should work

[thin panther]

for getting a player character it makes sense to use the more lightweight get player character, than the very expensive get actor from class

[fierce stump]

It's hitting what it's supposed to be hitting, but it doesn't seem like it's hooked up to hitting a pawn/character; not sure how to do that, either @foggy dew

[trim matrix]

makes sense

[foggy dew]

So if you put in a Get Display Name -> Print String for the Hit Actor from the Hit Result, it gives the correct actor, but the Apply Damage event doesn't work?

because if that's the case, I have no idea :p

[fierce stump]

The Apply Damage event doesn't work at all, I'm afraid

Works just fine on the explosive barrel I set up, but not on the NPC

[teal oasis]

Hey guys. I create a crosshair for my thirdperson character, but when my character shoot a linetrace, is not in middle of a crosshair. how can I fix this?

[fierce stump]

you're kidding me.

Apparently all I needed to do was change the collision preset in the capsule component from Pawn to PhysicsActor

[zealous fog]

Line trace from camera

[teal oasis]

thanks

[zealous fog]

Np

You're crosshair is on the camera if you think about it

Not on your character

[teal oasis]

yeah but I need on my character

[zealous fog]

Your*

But its third person

So you can move the crosshair without moving your character

Your camera is moving

So you need your line trace to move with your camera

You can still have the bullet come from the character

Think about it 🕵️‍♂️

[teal oasis]

didn't understand exactly 😦

[zealous fog]

What part don't you understand?

[teal oasis]

I try to fix it with project world to screen but its not that easy. I need some math I guess

[teal oasis]

I need that line trace shoot from my character

[zealous fog]

Why

[teal oasis]

becouse I dont have a projectile and I show my arrows only with linetrace . this is the work limitation For

[zealous fog]

You get a trace from the camera

Then move the projectile from character to the trace hit

[teal oasis]

Yes I got it. but no projectile. I am limited to use only linetrace from my boss

😦

[zealous fog]

Then you perform a trace from the camera, and then perform a trace from the character to the point your first trace hit

It's a silly way to do it

But it should work haha

[teal oasis]

aha you mean my performed linetrace is camera but show character linetrace on the screen right?

[zealous fog]

The third option would be to have your character follow the rotation of your camera

Like the upper body

So that a trace from your character would always be the same as the trace for your camera

[unreal tusk]

Would anyone mind explaining what the blocking hit result is?

Greatly appreciate ya in advance 😛

unreal docs just says "True if there was a blocking hit, false otherwise."

[zealous fog]

Have you read the documentation on collision

I think it should be in there

[unreal tusk]

Ah I think i see, collision document says "Blocking will naturally occur between two (or more) Actors set to Block. However, Simulation Generates Hit Events needs to be enabled to execute Event Hit, which is used in Blueprints, Destructible Actors, Triggers, etc..."

[obtuse herald]

Afaik it's false if it was an overlap collision and true if it was a blocking collision

Like if you have an overlap sphere and you trace through it you still get a hit result but it's non blocking

But if you have a wall and trace through it's blocking

[zealous fog]

I dont think your traces are always blocked

With multitracing

You can set up certain objects to block

[obtuse herald]

Yeah

[zealous fog]

And tben use this to know if that's what happened

[obtuse herald]

It depends on collision settings and stuff

But a wall is usually blocking

Write your own physics basically

[sand bloom]

Yeah you could fake physics

idk about the best way but using lerp or movement input with a forward vector going towards the center of the tornado works for getting your object there

Once there you could use a spline making it rotate in a circle around it or use random clamped movement inside your tornado bounds pretty easily

[zealous fog]

If you're gonna be faking physics might as well put the effort into doing physics

[obtuse herald]

There was a node stimulate projectile path or something along does lines

Finterp the acttor to the tornado center

[trim matrix]

how come when I hit play and end it, it'll sometimes give me an error for a reference but then won't. I like replicate it each time and it will do this off and on again. but the weird thing is it still works the way I intended to work.

should I just make it better?

[zealous fog]

Technically that's physics if you got gravity enabled 😎

Should look pretty good too

[obtuse herald]

And after that finterp it away via the points returned by said node

[zealous fog]

@trim matrix are you using is valid nodes

[trim matrix]

what you mean valid?

like am I getting any errors within the BP?

[zealous fog]

I would recommend starting to go through the unreal learning website

There are a bunch of beginners resources that should get you started with these kinds of issues you'll run into when you start out

[trim matrix]

alright

[zealous fog]

Yeah not that I don't wanna help it's just that those resources will help you out much more than just solving the problem for you

[trim matrix]

I get that and I'm not taking it personally lol

I appreciate it my man

[zealous fog]

Where is that blue line going lol

It just disappears

[obtuse herald]

It goes to GetActorForwardVector

You need a start location for the LookAt node

But you're giving it a direction

No

Location of array elem

ye

[zealous fog]

Also, I wouldnt do this on tick

[obtuse herald]

Needs to be on tick tho

[zealous fog]

And I would cache the overlapping actors because using a for each loop on a pure function can be funky

[obtuse herald]

That's fine in this case actually

The output of that pure node will only change between frames

And the fir loop is running in one frane

You probably want to convert the rotation to a direction

And multiply that by some value

And use that as offset

[zealous fog]

True but it will still evaluate the pure function on every impure call

Which is quite inefficient

Especially in a for each loop

Which is basically a bunch of impure functions

You should really always use variables when looping

[obtuse herald]

I would rate it as overoptimising in this case

[zealous fog]

I dont know, if the tornado is big that array could get pretty big too

I dont know how it'll be used

Just pointing it out

Personally I would do an event based system, when the player overlaps the tornado you enable tick, and on tick you move the player closer. When the player stops overlapping you disable tick

[obtuse herald]

Well I mean if he would filter for actors I can see that

[zealous fog]

Is it really over optimising when it's just a good general habit also not that much effort just promote to variable and you're done

[zealous fog]

This is probably a good way too btw

[obtuse herald]

It depends

When you put every value you retrieve inside its own variable then you're most likely just bloating your actor

But for for loops it's fine

[zealous fog]

Just make a Other category and throw it in there 😎

[obtuse herald]

But there is also memory consumption

[zealous fog]

I would just say generally if someone is running a for each on tick its good to advise them to cache the result and clear it when you're done

[obtuse herald]

But granted you have to really try to make that actually a problem

[obtuse herald]

Yeah

At least with pure functions

Especially with pure randomize functions

Who ever had the idea to make GetRandomFloatFromStream a pure function must be a devil

Not only do you get a different result on every call

You also internally change the stream variable

[zealous fog]

I spent 2 hours today trying to find a dumb reference to an actor that takes up like 1 gb

[obtuse herald]

It's pure hell

[zealous fog]

Turns out I had a variable type of that actor 😭

[obtuse herald]

1gb is eh

[zealous fog]

They should have that come up in searches lol

[obtuse herald]

A lot

[zealous fog]

Yeah I know I wanted to migrate my project and not migrate that actor

It was the skeletal mesh and textures

[obtuse herald]

Ahh

Yeah

That can add up fast

[zealous fog]

Silly me

It was in the interface too

Didn't make the search easier lol

Anyways I'm off to bed cheers

[supple bane]

So I have a rhythm game and the whole point is you can use any song U want and the game will make it for you, and I have an idea, instead of downloading the .wav file and using the audio there, you can use youtube link for the audio

Does anyone have a way to pull the audio from a youtube video and use it with synesthesia NRT's

[obtuse herald]

idk know about the second half but youtube-dl is a great library

However you can only really access it via raw os command calls

And I think that's only possible in cpp

[supple bane]

exactly

I found threads saying they found a solution and were even able to use the videos, but the link they provided doesn't work anymore

[obtuse herald]

I mean you could probably fetch it via http request from some yt to WAV converter Website or something

Or setup an youtube-dl API sever

[supple bane]

I could just use the website plugin to get the video, then get the audio from the video playing in the background

then I could have the video playing behind the game

[obtuse herald]

But ads

[supple bane]

yea...

[obtuse herald]

I mean ig it would at least be entirely legal that way

[supple bane]

yea

[obtuse herald]

There is also a way to script stuff in python in ue4

[supple bane]

really?

[obtuse herald]

But I don't know how limited you are there

[obtuse herald]

yeah

[supple bane]

I dont know much of python

Ill try the first option then come back

if problems arise

[supple bane]

tysm

[obtuse herald]

You're welcome

[supple bane]

it works kinda,

embedding it doesnt work for copyrighted music

so I try to not embedding it

but there are adds now

so if you want it to work you just gonna use an unofficial video xd

[small halo]

is there anyway to slow down a sound in unreal

[faint pasture]

Pitch control.

[small halo]

and is there any way to sync sounds with timelines bro?

i have a trap which is using a timeline and currently it syncing it with delays but requires perfect timing. is there an easier way?

[supple bane]

anyone know a way to get the audio from a web browser widget?

[tight schooner]

IIRC a timeline can output events too

[small halo]

IIRc?

[unique harness]

Show the timeline logic

[small halo]

fairly simple

https://gyazo.com/6f1f47d4986b0abaf878ce1c043a95ba

[unique harness]

That's the curve, what is the timeline doing

[small halo]

make an object swing side to side

[unique harness]

seems the correct way would be to use an animation and tie the sound to it

if that's not possible then you can check the value for the peak of the curve and play the sound at the start/end and peak

[small halo]

yeah thats what iv been doing

thanks

[unique harness]

If I remember correctly

What is the situation that you need to calculate this?

[unique harness]

https://math.stackexchange.com/questions/543961/determine-third-point-of-triangle-when-two-points-and-all-sides-are-known

seems from the first answer, it's not implied that it's a right triangle

[small halo]

https://gyazo.com/b1f95dd787d9b18b99c56b105df04b19

is this the correct way of using timers by event

if so its not printing hello every second

[tulip mason]

Something has to call test1 from somewhere

[small halo]

so begin play

if i want to call it every second from when the game starts

[tulip mason]

Basically

[small halo]

still didnt work

[tulip mason]

Then there was no begin play. That's how timers work though. Means it wasn't created in game for whatever reason.

[stuck hedge]

is your actor on the map?

[tight schooner]

If I recall correctly you can make an event track for a timeline, and thus have the timeline play audio at the moment of its choosing

Also timers should just work, otherwise they're not getting called, or they're getting repeatedly called which will reset the countdown time. (Or your game is paused, or time dilation is set to something weird, or the actor is getting destroyed, or...)

[obtuse herald]

Kinda eh late but you can convert the Alpha angle to a vector direction via cos/sin and multiply it with b (the side), then add the position of A to it and you got the position of C

[velvet dagger]

i hope i'm not interrupting anything, but when i use vinterp, it stays at the start location, anyone know the problem to it?

[obtuse herald]

How do you call it?

[velvet dagger]

im trying to make the object move towards a line trace hit

when i'd print the output of the vinterp, it'd always be at the actor location

[obtuse herald]

You need to call it every frame until it's at it end location. And don't forget to connect delta time with world delta time

Yes

Or the other way around

Yepp that should work

[velvet dagger]

OMG THANK YOU :)))

the problem was world delta seconds i had no c l u e i was supposed to do that

[obtuse herald]

You're welcome

[obtuse herald]

Ah right you probably want to rotate the direction vector

Cheap way is to convert some offset angle to a direction vector, add both direction vectors together and normalize it

[rough cedar]

Is it possible to store a spline from an actor on traced hit?

[rough cedar]

nvm i figured it out 😄

[lucid nebula]

How would I go about adding a ranked system that carries over with the player account

[timber knoll]

Save the data on the server, linked with a player ID or so

but that would be #multiplayer

[lucid nebula]

Thanks

Now time to figure out that

[timber knoll]

Actually I think EOS can also do this, but not sure never used it before

[lucid nebula]

I also gotta make it so it’s ONLY the rank and xp that gets carrier over

[timber knoll]

there's a seperate channel for #epic-online-services as well 🙂

what else would you carry over 😛

[lucid nebula]

Player health etc? Which I need to figure out if it’s possible for it to not carry over

[timber knoll]

That would be a very weird thing to save onto a server

[lucid nebula]

Welp that statement doesent help me at all

I gtg

[odd spade]

hi, is there any way to select gamemode at runtime? Like before you open a map? Or do i have to make multiple maps with gamemode overrides?

[timber knoll]

It might be possible through C++, but not blueprints.

[obtuse herald]

you can override the gamemode via optional parameters in the OpenLevel node

but I don't know the exact syntax

apparently it's ?game=/Game/PATH_TO_BP
example: ?game=/Game/Blueprints/GameModes/CaptureTheFlag.CaptureTheFlag_C

[odd spade]

Oh sweet, that works. Thanks alot 🙂

Looks like you can create shortcuts for the gamemodes in the project settings too.

[timber knoll]

Ooh I didn't know about those parameters 🤔 interesting

[chrome nymph]

whats the likely reason i cant use a macro i imported from my other project?

i imported the function library and macro blueprint library - i can access the fn lib but not the macros

[onyx wing]

Guys, I need an advice, which way should I make revolver reloading system? I need to make reloading variants with different amount of rounds that already in the revolver drum. For example, animation when there are two unshot rounds in drum, and we taking out one that we shot, and putting two new rounds for example. I mean there are huge amount of animations I need to make if there are not proper way of doing it
(sorry for my eng, explained as I could)

[obtuse herald]

depends on what parent you used for the macro lib and where you're using one of it's the macros

[timber knoll]

Sounds like something you want to use animation montages for, where you can choose to repeat an animation X amount of times or start at a certain point in the animation (which you could use for reloading the actual rounds back in)

Once reloaded, or you want to cancel reloading you could then jump to a next section inside the montage (to close the drum again)

[onyx wing]

how can I jump from one section to the last section of animation?

[timber knoll]

Notifies or so, you can read up on montages here: https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/AnimMontage/

[chrome nymph]

i dont think i have a paretn defined for the macro lib?

i just selected the macro i defined in my older project and clicked migrate to my new project

[onyx wing]

should I play character reloading movements animation and gun reloading animation as separate two animations or as a one?

[timber knoll]

Well you kind of have to make the weapon and character seperate unless you only have 1 weapon

[onyx wing]

hmm

and with those montages I can make differents variations of reloading?

You know, I need to make reload like in Insurgency Sandstorm for example

it's perfect in it

[timber knoll]

That's all up to you, montages just allow you to have different animations be split up into sections that you can repeat and notify when done/start from a certain section

[odd ember]

I don't get why people are so set on using montages where there's an animBP available for the taking with more than adequate functionality for this
