[dry pecan]

How do I setup input axis? Same thing for input action?

[faint pasture]

but you may want to consider your weapon being an actor, up to you

if you want a weapon to be a bundle of mesh, collider, sound, abilities, particles, make it an actor.

[lofty rapids]

use the same event, can you move at all ? did you try the setting ?

[lofty rapids]

just use the event you had because it works, the x and y axis are correct right ?

when you press the keys you get 1, -1 ?

[obtuse minnow]

there is any way to call the player enhanced input from another actor?

[maiden wadi]

You enable input in the actor,.

[faint pasture]

On that same note, is there an easy way for AI to directly call input events? It'd save a layer of events that way.

[errant osprey]

Thanks for the replies, Adriel.

[obtuse minnow]

adding the maping context or?

[dry pecan]

I still can't, I think my blue print may be beyond saving, btw the character you used, was it a new player character?

[maiden wadi]

Partially. There are three things required to gain input into an actor.

You need the input mode to be Game or GameAndUI.

You need the enhanced input context mapping applied, this is just a filter basically. The real usecase is meant to allow conditional input frames on top of existing ones.

And you need input enabled on the actor.

For the last one, three classes are exception to this. The PlayerController, The Level Blueprint, and the player's possessed Pawn. All three of which are considered separately when building the input stack along with actors that have had input deliberately enabled via EnableInput.

[lofty rapids]

ya it was fresh character

i didn't used enhanced input, but it should work

it's not moving at all ?

did you try hard coding the values ?

[obtuse minnow]

Ty for the reply

[maiden wadi]

@obtuse minnow Since you read C++, this function in particular is useful to look at.

[dry pecan]

cant really code

[obtuse minnow]

thats pretty clear

[lofty rapids]

you may want to watch some basic tutorial on node and how they work, what events fire when, variables, functions stuff like that

[obtuse minnow]

its just pushing the input component into the stacks ya?

whenever you activate the input

[maiden wadi]

Correct.

[obtuse minnow]

and if it is null?

inputcomponent

I guess it crash

[dry pecan]

I think I should do a new character, this character is in too much of a mess

[maiden wadi]

It's managed internally to avoid that.

[obtuse minnow]

Thats nice

well somethimes I preffer that xd

[lofty rapids]

if you start fresh, disable gravity, set the gravity scale to 0.0, then set that setting i showed you, you'll be able to move up/down as well as left/right forward/back after you set the correct movement in the bp

just have to put it in the code, are you using a template ?

i just used a blank character in a blank level to test it, but it shouldn't matter

[obtuse minnow]

also, there is any way to get a value from 0 to 1 depending on how much you press the key in the action value. Instead a 0 or a 1

with IA

[dry pecan]

Wait but I was avoiding to code as I was going to do it all in blue print

[lofty rapids]

well theres no need for c, bp is fine, just choose bp

[dry pecan]

You said code though

[lofty rapids]

i mean it's code in a sense, but i see what your saying i meant blueprints code

[maiden wadi]

Usually an axis mapping. You use them for things like gamepad trigger keys and such.

[dry pecan]

Ah ok my apologies, can I see your Bp as a reference?

[lofty rapids]

it's suggested to use enhanced input system like you did i just did what i did for test

also you can use the up vector, and right vector

but here i just hardcoded the movements

and the scale is like it should be 1 or -1

[obtuse minnow]

but float mapping shouldnt also give that smooth values?

[maiden wadi]

Axis is the float mapping

[obtuse minnow]

oh ok

[obtuse minnow]

but then Im doing something weird

because action value never gives me something different from 0 or 1

[maiden wadi]

What key are you testing it with?

[obtuse minnow]

Shift

[maiden wadi]

Shift has no middle states. It's pressed or not.

[obtuse minnow]

oh

[maiden wadi]

The only thing on a PC with variable axis is usually MouseX and MouseY

For real axis usage, you usually end up on Gamepads with triggers, and analog sticks.

[dry pecan]

I did as you saw but the character wouldn't move, nor do I know to how to do up and down

Neither

[obtuse minnow]

but thats weird because in unity you can get the raw value from 0 to 1 in keycodes

maybe they are simulating that

with a lerp internally or something

[lofty rapids]

you character shows up tho ? or you dropped it in the level ?

[maiden wadi]

They would need to be. Keyboards aren't made with half states. Your keys trigger when you hit the actuation point.

[obtuse minnow]

ye they probably do that

thats why I was looking for that in unreal

but I can simulate it with the trigger time I guess

[maiden wadi]

You could probably extend the input component with a new setting for that. Or just turn it into some sort of macro that houses a local float to maintain the lerped state for an interp to

[obtuse minnow]

that could be a cool feature

[dry pecan]

Shows up

[obtuse minnow]

I will look into doing that

[lofty rapids]

ya see what a new character does idk why the add movement input just wouldn't work or what kind of settings you would need to change

but a normal character

you just plug that stuff in

like i said tho it looked like most of your stuff was working as far as the enhanced input goes

1, 0, -1 is expected

[wheat citrus]

So im trying to implement a beam weapon in a project and I'm using a line trace that shoots as fast as the engine will allow to see if the beam is hitting anything. The issue is that with fast mouse movements there is still a huge gap between the hits and if there were another player between them they would not be hit. You can see this in the video, with the red line traces. One thing I did to cover a bit more ground is to connect each hit with the preious and trace that as well (pink traces) to see if there was a player along the path that was missed. However that only works if that player was at the same distance from the shooting player as the previous and current hits. If they were closer or further away they would still be missed. Any ideas on how to solve this? I wasnt able to find any tutorials for beam weapons either.

[maiden wadi]

In general your choices are to use a sweeping capsule. As this would sweep along the moved path each frame.

Or you can save the last trace done the previous frame. Then in the next frame, determine your new trace, and then fill in the gaps from the old to new with some simple lerp vector math. Save the results of all of the traces, filter them down into single targets so you don't apply damage twice.

[dry pecan]

what should i do then?

[lofty rapids]

show what you have ? you still using the same thing ?

[lofty rapids]

i thought thats what you were getting from the axis values

so that part was correct

you just needed to get the input correct

do you have your own animations and skeleton for a fresh character ?

[wheat citrus]

So the lerp you're suggesting would look like the left one correct? If the two red ones are the hits I could lerp between them and shoot the blue traces? For the capsule sweep I dont quite understand how that would solve the issue. From what you described I understand that to perform the blue capsule sweep on the right example, but that would miss all the green space infront of the hits and all the space behind aswell, excluding the capsules thickness.

[faint pasture]

Although I'm not sure sweeps can rotate?

[maiden wadi]

The capsule sweep is not a really good idea. It would extend from the weapon to a very long length It would work, but you would need to save any swept movement each frame, along with a tick check to see if it's overlapping damageables, filter and apply and then clear the list. Bit messy.

But yeah the first one is what I mean about lerping the traces. You should be able to artificially fill enough space to make up for the gaps at least as far as a normal player would care for distance.

[wheat citrus]

oh yea I see what you mean with the capsule sweep, that would indeed be quite messy but also the most accurate

though Id have to test its performance

[maiden wadi]

It should be as simple as some basic lerping of the start and end direction vectors. Add as many sections as you feel necessary. Also remember to test this with t.maxfps 30 or so for best covered results.

[wheat citrus]

game is already bottlenecked by cpu frame time

[faint pasture]

how

everything is in BP?

[wheat citrus]

yea

[faint pasture]

lol

that'll do it

[maiden wadi]

Oof

[wheat citrus]

also using general movement component which is heavy on calcs

[maiden wadi]

Pick up some profiles. Best part of gamedev. 😄 Shaving off miliseconds and keeping logic intact.

[broken wadi]

The editor itself adds like 5-10ms so make sure to test perf using a packaged build. It appears as slate in unreal insights.

[maiden wadi]

Fun note, you can shave off most of the editor time by just minimizing it in the background. The majority of it is slate and extra viewports, which won't run when minimized.

[wheat citrus]

oh good to know cause in that case it wouldnt be a big issue, current frame time hovers around 9-12ms limited by cpu

[faint pasture]

oooof

[wheat citrus]

(in editor)

[faint pasture]

lets see the breakdown

profile with launched game, not as good as cooked but closer

you can just right click uproject and hit launch game

[maiden wadi]

Can also do it in Standalone.

[faint pasture]

I'm a perf nut for my systems, i got my 1D physics down to 0.1 ms/frame with 1,000 devices but haven't been able to test with a big mix of devices yet.

in editor

[wheat citrus]

actually standalone is broken atm cause of some settings, another team member is taking care of that so I have nbo idea how to fix it. But we did do profiler tests and the majority of the frame time was the General Movement Component plugin

[faint pasture]

how many pawns moving around?

[wheat citrus]

in the test I think it was two

[faint pasture]

what

[maiden wadi]

O.o

[faint pasture]

get a refund lol

unless you're on Intel Atom or something

[wheat citrus]

nope i714700k

[maiden wadi]

That's insane. I'd be vaguely curious to see those profiles.

But on that note, a few extra traces won't harm much.

[faint pasture]

yeah there's no way 2 movement components does that

[wheat citrus]

I'll try to get back to you on that but might take a few days

[faint pasture]

can GMC have movement physics defined in BP?

[wheat citrus]

not sure, but we turned off physics simulated movement and are using our own movement implementation with GMC

I think it can tho

[faint pasture]

I mean is the code that's running on tick to move things and trace etc written in BP?

when you say your own movement implementation is that BP?

[wheat citrus]

oh yea we use BP for everything

[faint pasture]

that theres ya problem most likely

the framework of GMC is probably doing almost nothing but your BP movement is eating you alive

[wheat citrus]

I did wanna look into cpp when the new Mover component comes out in 5.4. Hopefully that should solve it

have some cpp experience but none with game dev

[maiden wadi]

What is the point of GMC anyhow? Seen it a couple of times, never looked at it.

[faint pasture]

I think it's like CMC but more general and more exposed to BP

[wheat citrus]

it just takes care of replicated movement which can otherwise be a pain in blueprints

[faint pasture]

dunno, I just use physics for everything lol

[wheat citrus]

./impossibel to do in bp

[maiden wadi]

Cause XB1 and PS4 already can't handle CMC, lets add BP to it? O.o Nope.

[faint pasture]

I mean it's possible, for varying definitions of "working"

you could be an insane person and replicate the CMC in bp but that'd be silly.

[dry pecan]

wait I need a skeleton?

[maiden wadi]

I love BP. I do a ton of work in it. But there's some things that just don't belong. Like this wildly looping shit I'm doing for procgen maps. 😄 And Character movement.

[wheat citrus]

also this is all of our (dev teams) first project in game development so we all dont really know what we're doing

xd

its fun tho

[maiden wadi]

I'm also still traumatized by performance issues. We recently spent a year optimizing for consoles.

[lofty rapids]

well you need a character

[faint pasture]

I did my first draft of overlapping model wavefunction collapse in BP

it was..... uh, slow

now it can do a 100 x 100 in like 5ms, trying to cut that down though

[maiden wadi]

I catch myself doing things in BP I already cleaned up on the other project and cringe... buuuut, it's a prototype, we fix later, right? 😂

[faint pasture]

This prototype was all BP, I'm still trying to move it all over lol
https://youtu.be/Datugg_ZS3E?si=iKYObYAIbQjuwiZa&t=282

[dry pecan]

.....what if I told you I was using a cube

[junior quest]

Im trying to make a player controller with the enhance input system and this is working but I dont know how to adjust my walk speed

I tried multiplying the scale and the vector but neither changed it

[lofty rapids]

ig that works is that your character for now a shape ?

your movement should still work just fine

[faint pasture]

Move that code into your character BP

What you have can work but it's awkward

PlayerController =/= The Thing That Makes Your Pawn Do Stuff

[lofty rapids]

maybe actor forward * movementspeed ?

but normally i do that with set max walk speed

so that it still goes smooth from a to b

[faint pasture]

How are you trying to adjust it?

default settings on CharacterMovementComponent has very high acceleration, so it hits max speed very quickly

What are you after?

[craggy flicker]

Hey yall, how sensible is it of have custom functions in actor components, then use those components as identifiers for different actors (as opposed to having a cast to each time)

ty

[faint pasture]

yup that's a great way to go

I'd at least have the component do something

if it's just a tag then use a tag

[craggy flicker]

I've recently started using actor components about a month ago and they're a life changer for prototyping

[faint pasture]

yeah they're great, just about all I do in C++ is subsystems and actorcomponents

[craggy flicker]

subsystems are extremely helpful yea

[faint pasture]

I've literally never made a C++ actor For Real™️

[craggy flicker]

i use subsystems for networking logic

[faint pasture]

how

they don't network

[craggy flicker]

such as authentication

[faint pasture]

ah

Steam/EOS is good enough for me

[craggy flicker]

made one after looking at a few guides on epic games auth

yea, this one was in c++

anyways, ty

[faint pasture]

I use subsystems for engines or scenes.
ProjectileSubsystem, VisionSubsystem, stuff like that

[junior quest]

Im trying to learn how to make a player controller in UE using enhanced input mapping and then continue following an older tutorial, but I see that component on the character now

[faint pasture]

Input is automagically enabled on your possessed pawn, you can just slap input events on it

look at the template projects

[dry pecan]

It should?

[faint pasture]

note the shape won't be your collider

visuals only

CMC wants to use that capsule as the movement collider, full stop.

[lofty rapids]

ya you can just put a shape in there it should still move

something must have been set wrong or something with your character

a fresh one will most likely work if you set it up correctly

[dry pecan]

would it be a problem I used the character parent class or was that ok?

[lofty rapids]

i mean thats what you want a character, you could use a pawn otherwise

you want to control it so i would use one of the two

but a character works just fine

[junior quest]

These?

[faint pasture]

no just the startup template projects, 3rd person, 1st person, vehicle, etc

[junior quest]

oh that makes sense

ty

[round spruce]

how do i resolve this conflict i want to keep my tryroll version and discards main whato i delete and what do i keep

[lofty rapids]

what is tryroll ?

[round spruce]

a branch i made

merging it with the main

[lofty rapids]

this isn't #blueprint specific maybe a different channel

[faint pasture]

#source-control

[lofty rapids]

i was gonna say #engine-source

[lunar sleet]

That’s for modifying the source code

[lofty rapids]

makes sense i wasn't sure if thats what they were doing

[dry pecan]

question, would this be a problem? I thought this meant this this is the main player controler the character would use, not AI

[lofty rapids]

just hit x on that, set your controller in the world settings

and then the controller possesses the character that you have set

spawns it and posses it

using the controller you set

[lofty rapids]

i'm pretty sure thats if your not possessing it it uses ai, idk much about it

but you don't need it to make your character move

[dry pecan]

so for some reason my W takes me left and my S right

[lofty rapids]

well for one thing i would just start with one axis

[dry pecan]

I wanna figure out up and down

[lofty rapids]

because your using right vector

i'm guessing

[lofty rapids]

try the up vector

[faint pasture]

howd you do that lol

[dry pecan]

nothing , wouldnt go up

[faint pasture]

What is Vector Up?

[dry pecan]

you go up right?

[lofty rapids]

default land movement mode

set it to flying

[dry pecan]

well I can go up and down, but not left and right yet

I can float!

question, how do I set a level main camera?

like without needing it to be in a character

[faint pasture]

depends

There's all sorts of automagic stuff going on, I'd start by seeing what happens if you have a camera actor in the level and no camera component on your pawn

There might be some in-built stuff for camera selection that'll just grab it

if not, you'll need to set some camera as your view target

[dry pecan]

well I'm planning to have my camera be not part of the player character its gonna stay still while the player moves all around

for some reason it went full fps when the player had no camera componet

[faint pasture]

yeah defaults to actor transform

[dry pecan]

what do you suggest I do?

[lofty rapids]

will the camera always be still ?

[dry pecan]

yes

[lofty rapids]

so it won't be moving ?

[dry pecan]

yes

[lofty rapids]

you can set the location of the camera on tick

[dry pecan]

how so? in the camera actor?

[timber sable]

Is there a way to convert the 3d size of an object to its size in the viewport?

[pastel garnet]

hello, I have this actor (rock) in my scene that I want to move around and keep in its altered location after the sequence has elapsed. but it keeps reverting back to its default state (second image).

[lofty rapids]

there may be a better solution but that would work

[craggy flicker]

How should I adjust my "FindNearestRoom" function so all rooms are connected? At the moment I just use the Find Nearest Actor node

You can see the two rooms on the right aren't connected to the main dungeon

would i have to use minimum spanning tree stuff

[lofty rapids]

in your character

[dry pecan]

oh it worked :D, thank you so much

[maiden wadi]

In short, you take it's world space bounds and project each corner to screen space. Then use those points to get a min/max to make a Box2D out of.

[lofty rapids]

all tho that worked, if you run into any problems or want something more performant you'll have to do some camera manager stuff, idk how to do that i only know how to set it like that

[craggy flicker]

i'm a bit indecisive on this, mostly because it'll determine the flow of the dungeon. i currently have a "Connectors" int on my dungeon room component, should I just keep drawing paths to new-nearest dungeon rooms until the amount of paths equal the connectors?

I don't think that would work mostly because there will still be a very good chance of room clusters being disconnected. How can I ensure that each room has a possible path to one specific room? Maybe A* stuff?

[dry pecan]

I just need to figure out how to do invisible borders

[lofty rapids]

so your character doesn't go out of the screen ?

[dry pecan]

ye

[lofty rapids]

will you always be that distance or can you zoom ?

[dry pecan]

same distance

[lofty rapids]

just put some shapes around it

the character will bump into them

this takes a little bit to get right

you got to really work on setting the camera and everything just right

and if you want to change it your f'd

[dry pecan]

guess I need to figure out then how to have certain objects pass said shapes

[lofty rapids]

well i would probably go ahead and spawn them in

calculating based on distance of camera

probably some magic numbers will get you a good box

this way you could zoom in and out

to get your view just right

or you could do some maths

and clamp the players location

[dry pecan]

well I guessI could just have them spawn in, after all its simply just flying objects that hurt upon touching

Actually need to ask, how do I set a default animation to a character?

[pastel garnet]

any suggestions guys, I would really appreciate

[lofty rapids]

i usually make an animation bp that has a state machine for movement

so you can have other animations

but i think you can just set an animation if you just want one

i think you need skeleton for that stuff

[dry pecan]

Yeah that's what I'm trying to figure out, I'm giving them an idle since the model I'm currently using is also used for a bunch of animation assets I have

[lofty rapids]

is it a skeletal mesh ?

[lofty rapids]

in the details

under animation

in your animation mode

pick use asset

[dry pecan]

it worked!

[lofty rapids]

but idk how you would go about changin that dynamically

i would suggest an animation bp

you can do some wild stuff with one of those

[desert juniper]

MST would be good

[pastel garnet]

that might have to be #cpp try and ask if anybody can help

[desert juniper]

you can combine delaunay triangulation with an MST graph

[bitter star]

How do you find the "set found list"?

[desert juniper]

you can set that up with delegates

Side note, creating a binding is typically not a great practice. It runs on tick, and if your value doesn't change, the UI still has to redraw

in both cases, delegates are predered

that's why I said side note.

[pastel garnet]

Then delegates (event dispatchers) are the best case. you can use this resource https://www.youtube.com/watch?v=r20VEPH_e0o

[nimble wasp]

Working on a Simon Says like game. I want to store the Simon's sequence in an array. I know to clear the array first - but how do add specific numbers to it? For example, if the first index = 3 and the 2nd = 5, how do I store that?

[pastel garnet]

are you looking for something like this?

[bitter star]

I have a light that turns on red when when overlaped. I want it to turn blue when overlapped and if a switch has been flipped. How do I do this? Gate?

[pastel garnet]

i believe it does

unless you have some sort of delay

[desert juniper]

no it is not guaranteed

[pastel garnet]

really, i haven't encounter it not happening in the same frame. (i might be wrong tho)

[nimble wasp]

Thanks! I'll try this.

[desert juniper]

yeah, it's' not guaranteed.

[pastel garnet]

good to know, thanks for correcting me

[pastel garnet]

well you could use a bool bSwitchOn to detect when the switch is on or off

[bitter star]

Thanks for the reply. Its actually a bit more complicated than this. I send commands through OSC. When I send the value "0" I want the actor begin overlap to trigger the custom event A (red). When I send the value "1" I want the actor begin overlap to trigger the custom event B (redblue). How can I achive this?

[desert juniper]

not sure i understand your question entirely
but your event dispatcher can take in a variable as an input

can you ELI5 what your end goal is? without explaining what your process is

[desert juniper]

what if instead of making InteractionRange a float var, you make it a function GetInteractionRange

and in that function you calculate what the interaction range is, and output it as a float

yeah, each actor overrides it

Make the function virtual. i don't know if you explicitely need to make it virtual in BP. one sec

oh nvm i see the actor needs to calculate it, not the component
well, you can do so via a interface

not easily lol

it's the equivilant of dumping and redrawing the entire UI each frame

if you want the equivalent, just calculate it on tick?

unless you can just calculate what the interaction distance is on the AC, then an interface on the actor is probably the best way

which seems more anoying, because in each actor you'd have to implement this function

would it? you can code some generic things
like distance from pawn to actor
actors health
actors mental state and well-being
and have boolean checks to see if it should consider these in the final calculation

like an interface? 😉

[pastel garnet]

i have never use the function pointer in c++, how does it work?

i think im going to look into it. might make my life easier

so the function that is dynamically determied by the class has the return the same type

i am just realising how many situations that would have helped me 🥲

thank you for the explanation

[nimble wasp]

Figured it out

[bitter star]

@pastel garnet does this make sense?

[pastel garnet]

well I can tell what your trying to do so I think it makes sense

[bitter star]

lol I meant how would you achieve this?

[dry pecan]

hello, I'm currently trying to replicate the shooting done in the game, I was thinking ray cast but I'm not sure if thats the best way, any suggestion on what I can do? https://youtu.be/cWiT-VuPgMk?si=OWEXlmuNq-r0dEKh

[undone bluff]

get hit result under cursor

spawn projectile at the gun towards that location

[dry pecan]

should I make the gun a seperate actor?

[trim matrix]

Hello, I tried to replicate the WASD movement from thirdperson template on a new project. I've set up gamemode, created BP_PlayerCharacter and have its enhanced input cast to playercontroller. All done in PlayerCharacter BP. I've checked IMC setup and InputAction as well.

The movement works fine, but the pawn does not seem to rotate when pressing wasd accordingly. anyone know what I am doing wrong?

[undone bluff]

well, I never had any need to make a weapon an actor

if what I see in the video is all you want I don't see a point in that

I have an inventory system so my weapons are uobject with a soft reference to a mesh

the weapon specific stats are also in there as referenced data assets

without the inventory you can skip straight to just the data asset

[dry pecan]

can I ask how I can achieve this?

[undone bluff]

it's straight up a node in UMG

[pastel garnet]

@bitter star keep the code you already have and have a bool that tracks the switch state then perform the RED code or BLUE

[undone bluff]

actually it might even work outside and just use the player controller

not sure atm

yea, pretty sure that's the case

not on unreal right now

[pastel garnet]

ideally yes as it make it easy to make other gun types

[dry pecan]

umg?

[undone bluff]

unreal's ui designer

[dry pecan]

wait its not a blueprint node?

[undone bluff]

it is

I was wondering if it was an UMG specifc function for a moment but then remembered it's part of the controller

so you can use it there or in your character

[undone bluff]

in what way would it offer an advantage

[undone bluff]

yea it's a linetrace but it traces from the camera to whatever is under the cursor

you'll probably want to just do it by channel though

[dry pecan]

why's that?

[undone bluff]

well, I assume you want to just shoot at anything that blocks the visibility channel

[light flower]

Hello friends! Is there any way to limit the gameplay tag choices in editor ui for params when writing a blueprint, as we have with UPARAM(meta=(Categories="abc")) in c++ ?

[undone bluff]

not just at specific object types

[dry pecan]

yes, while holding projectiles will shoot forward

[nimble wasp]

How do I set a text render to display the entires in an array (integer array, so I want to display a string of numbers). I did a for each loop, looping through the array and printing each array element - but the text didn't change.

[undone bluff]

you are setting the text to every entry sequentially until the last one in one frame

[dry pecan]

can I ask how I would use the other inputs and outputs?

[undone bluff]

you will need to append or add text widgets (one per entry) to a vertical box or something

[undone bluff]

break hit result for the data inside

it'll give you a location

it's a struct

[nimble wasp]

What would I do here? I'm looping through and saving each element as text in a new array. I want to then display (set Text) all of the text, in order from the Text Array.

[pastel garnet]

having a separate actor (base class) allow you to define common functionality all guns will have like firing, reloading etc. and you can define animation montages to play when firing and reloading or basic locomotion animation blueprint that gets swapped out when that weapon it active (being held). there are other cases where you would like a separate actor it depends on the project which is why i said "ideally" you would want that.

[pastel garnet]

try this out

[undone bluff]

I feel like logic related to weapons should not actually be in the weapon itself, particularly reloading and firing are character functionality, though I can think of more extreme cases where it would make sense.

[dry pecan]

thankfully there's no amo

[undone bluff]

As for data having it in an actor is unnecessary and less convenient to work with

[pastel garnet]

well the character will be the one calling said functions in the weapon like firing, but i get the reloading part. still it all depends on your game

[undone bluff]

Yea, and I gotta say the actor setup is the most common I've seen

[nimble wasp]

I can't enter the string array into the text render. The text render only accepts text not strings. :/

[pastel garnet]

convert from string to text

[nimble wasp]

No luck. The text just disappears.

I'm really just checking stuff - I can do break points.

[pastel garnet]

is there any item in the array?

[nimble wasp]

...that's the thing. It doesn't appear there is. Ugh.

I'm trying to add a specific number to a specific index point.

But that isn't working I guess

[pastel garnet]

is notes played -1 a valid index. I would suggest adding print statements everywhere until you spot a problem

[undone bluff]

more importantly you cannot set an array element that doesn't exist

[nimble wasp]

Notes played starts at 1

[undone bluff]

you will need to add what you want to the array in order

or populate the arrray with placeholders and replace

[nimble wasp]

Gonna try that. I think I was getting confused because I was storing integers in the array and was worried it would return the index not the element

[dry pecan]

though I do need to make an actor for the bullets at the very least

[pastel garnet]

hit scan weapons you don't need that but projectiles yes you do

[undone bluff]

yep, you could just have particle effects for visuals only

for this type of game probably the right choice

[dry pecan]

but I need to aply damage

[undone bluff]

you are already hit testing for the location to shoot at

you are getting an actor and component reference right there

[nimble wasp]

@undone bluff and @pastel garnet you two rule. Thanks. That did it - just using Add instead of Set Array Elem worked.

[dry pecan]

wait really? but I want to apply damage only if the bullets are hitting and the bullets still come out even if an object isnt being hit

[undone bluff]

if the player places their cursor over an enemy and clicks, do you want that to be a guaranteed hit?

or should they be able to miss if the enemy moves away

[dry pecan]

can miss

[undone bluff]

yea, you will need the projectiles then

[dry pecan]

should I keep what I'm doing? will the channel thing still work?

[undone bluff]

yea the point of that is to determine where to shoot

[dry pecan]

what about my projectile BP?

[undone bluff]

that'll be actually dealing the damage then

[dry pecan]

so all the bullet will have the apply damage, spawn sound and fx

[undone bluff]

yea, though muzzle vfx and sfx don't need to be in the projectile

[dry pecan]

what can I do though for getting the bullets from point a to b?

[undone bluff]

well moving something is kinda gamedev basics and extremely widely covered

but unreal has a projectile movement component you can use if you want

[dry pecan]

oh right this

[undone bluff]

yea, every frame linetrace towards the target location by the distance you want to move per second in cm multiplied by deltatime, if nothing is hit move there

that's all there is to it

I'm off now, good luck

[eager narwhal]

is this where i can ask for help if im stuck on something?

[zealous moth]

Is there a way in UMG to create an animation object to give to any selected component?
For instance, I am making things pulse using a simple scale x,y from 1 to 0.9 and back to 1 over 1s.
Rather than create a million animations for each components, can this be streamlined?

[main lake]

depends on the type of help you need

[eager narwhal]

im having an issue with a damage system I just implemented. I have health setup and its working and I have it where both the player and enemy will take damage but no matter what value I put for my damage it just dies in one hit. If someone could help me that would be amazing

[main lake]

Why my characters spawn properly but i can't control it and my camera is on the floor ?

[main lake]

You need to show your code aka the default value of your health, how much damage you deal to your player and where the "death" logic is and how you coded it

[silent drift]

I'm struggling with a starting point for this so hopefully someone here could give me an idea.

How would I do an ledge hang check the best way? Since I need the player to only grab edges of platforms and not in the middle I assume I might need to or even three checks?

E. G.

1. So there is nothing above the ledge
2. Another one checking where the ledge is
3. a third that the player aren't on ground

I'm not sure if this is the best solution?

[gentle urchin]

Crossposting is against the #rules, avoid that please.

[main lake]

Sorry, But i have this issue for 2 weeks now and nobody can't help me 🥲

[gentle urchin]

Its been new things all the time.

Every step you take is a new thing

Still no reason to crosspost

[azure crater]

Is there any way to access the skyatmosphere settings inside blueprints? For PostProcess you can make settings, but the SkyAtmosphere is not allowing that?

Im very confused how to change the properties at runtime._.

I might be slightly dumb but you can just easily set each individual value.

[gentle urchin]

Not so dumb afterall ™️ 😄

[crude dew]

Not sure about this maybe someone can answer me xD I,ve been doing UE for a little while now and I cant see why this isnt working lol its so simple i think

So on BeginPlay i run Custom Event to set IsAttacking to true simple right.

[gentle urchin]

Sounds ok so far

[azure crater]

But it isnt True?

[crude dew]

Not setting to true

Default is false

[azure crater]

can you highlight the one in the outliner on the top right?

[crude dew]

I have highlighted the Variable in the Editor when playing

[queen heron]

am I doing something wrong here?
I can't get the event dispatcher to fire from the anim notifies

neither Event nor Binded return any tick

[crude dew]

Nevermind worked it out for some reason when I "lock" the editor to show a specific details tab it doesnt seem to update when theres any changes after i unlocked it and reclicked on the actor it showed updated values, I thought it updated in real time. So seems you cannot see a variable value change if you lock the details tab on an actor, seems weird.

[main lake]

Guys what's the node to get the active camera please ?

[crisp geode]

Need some help from you guys. Trying to create a tcg like mtg arena. Is there a way to create an array of data table's rows?

[crisp geode]

There is a node called Get Player Camera Manager, which returns a Camera Manager reference. This allows you to get and set certain values of the Active Camera tied to the Player Index, regardless of whether or not the Active Camera is part of the player referenced. (Took from internet)

[random pulsar]

hey

i want to make a clip on a white background appear images one by one with alpha effects ,can i make it in unreal or do i need an editing software?

[main lake]

Already check that but there's no "Get Active Camera" or something along those lines

[dark drum]

What are you trying to do?

[main lake]

Just to print the name of the active camera because I have an issue for 2 weeks now that I can't solve (check #multiplayer convo if you want) 🙂

[dark drum]

Datatables are pretty much a static map with a name for the key and a struct for the value.

[dark drum]

As an FYI, there's a tick delay before a possession is finalized. If a player joins the game and creates its own character and the same tick you destroy what they currently possess and have it attempt to posses another character, it'll fail. If you character already has a pawn and you destroy it, you'll need to wait a tick before you can have it possess a new pawn. 🙂

Edit: I assume this is the issue you're trying to resolve.

[main lake]

How to solve that issue / wait for 1 frame ?

[main lake]

Let me find the beginning of the convo so you can see the whole issue I have for 2 weeks now

[dark drum]

pretty much yea. It's only really an issue if the controller has already attempted to possess a pawn in the same tick which can happen when they first join a game and a character is automatically spawned.

[main lake]

#multiplayer message Here it is 🙂

[gentle urchin]

Longest convo of the year

[dark drum]

Yea what I've described is most likely the issue. If you have to destroy an already possessed pawn, you can call a timer by event for next tick and have it call a function that creates the new character and possess it the following tick.

[gentle urchin]

How is that even a thing 😅

Worth a shot at this point

[main lake]

So i do that in my "Spawn Player" function ?

[dark drum]

The only reason I know is because I was working on something a few months ago where as as soon as the player character was spawned, I unpossessed the default pawn, created an AI controller, made it possess the now unpossessed pawn and had the player controller possess a generic pawn. It ended up where both the player controller and AI controller thought they possess the same pawn. (which of course isn't possible lol)

[dark drum]

Most likely yea.

[gentle urchin]

Lol thats pretty weird . Well good note to make i guess

[dark drum]

Not sure if this will help but this is what I did when I experienced something similiar. Not multiplayer though and this was just in the character BP.

[dark drum]

Yea it is. Took me a good day to figure out, it was driving me insane lol.

[gentle urchin]

Glad we have simple pawns and pawn setup 😆

[main lake]

I'm not sure to follow how to do that on my side as my spawn logic is in a function 🤔

and you're using "Delay Until Next tick" which isn't available in functions

[gentle urchin]

Move it out

[dark drum]

you can use a 'Timer by Event for Next Tick'.

The hardest bit you would have to deal with is getting the character ref as you won't be able to return it on the initial function you have.

Edit: having said that, i don't think you actually use the return value anyway.

[main lake]

but I can't link an event to it as I can't create events inside a function, so that's what i have currently

[gentle urchin]

... move it out already

Convert to event

[main lake]

Like so ?

[dark drum]

Something like should work.

[main lake]

i already converted the function to an event, is that good ? 😄

[dark drum]

This would probally end up failing if you have multiple player controllers that need a new pawn.

[main lake]

Oh

Let me redo the thing to be like your last example

[dark drum]

Slight revision. Needed to handle the is not valid pin lol

So esensially, it'll handle destroying/unpossessing old pawns first, and then the following tick, create and possess new pawns.

[main lake]

What's the purpose of your "Pawn Required" array ?

[gentle urchin]

Its in the name

[dark drum]

It's an array of the player controllers that need a new pawn.

[gentle urchin]

Pcs without pawns

[gentle urchin]

is the set timer by next tick a 'called once' thing ?

so its automatically unbound after the call ?

I guess it is

[dark drum]

Yea, just called once.

Checking if the timer is valid probably isn't needed though with it being called the next tick.

@main lake The suspense of waiting to see if it works is killing me. 😛

[gentle urchin]

xD

not in blueprint

lucky you can get it at all 😛

best of luck x)

[main lake]

Now everything is broken in everly level 🤣

[dark drum]

What happens?

[young meteor]

Maybe a stupid question, but how do I make a this arrow mesh not rotate along with the character?

Right now it follows the movement of the character, but I want to control the rotation independently.

I can't seem to just drag it above the capsule.

[dark drum]

You could change the rotation from local to world on the arrow.

[main lake]

No character is spawned nor controlled 😄

[dark drum]

Does the create pawn function get called?

[young meteor]

Where would I do this? Don't see an option for it under details.

[dark drum]

Turns out you can't. o.O Odd you can't set it's transform like other components.

[young meteor]

what component can you do it with? Could just make it a child of such a component if that is a thing.

[dark drum]

You can add your own arrow component.

[young meteor]

Don't see an option for local/world rotation even for that component.

[frosty heron]

If the actor rotate, it will probably rotate still

Since its a child of the actor

[young meteor]

Ah, that is how you got it. That can be done directly for the mesh.
Testing..

[main lake]

the function "SpawnPlayer" is being called and the print "SpawnPlayer" is being printed but not the last print "End SpawnPlayer".

And I guess it's because of the IsValidtimer Handle being false as the first time it's null

oh my bad

that's my mistake because your example was using the "false" output

[dark drum]

I was just about to say that. 😛 But yea, if it's on true it would never start the timer.

[main lake]

Ok for the Host, it calls both "SpawnPlayer" and "Create Character" however i can't control him

On the client however I'm still in the ground and no character is being spawned

[gentle urchin]

Resign from multiplayer

😄

[main lake]

https://tenor.com/view/no-donkeys-shrek-gif-16041065

Here are the prints on the screen

[dark drum]

How do you add inputs to the player? on begin play in the character? If so, it probally needs to be moved to 'OnPossessed'. (with a check that it's been possed by a player controller)

[main lake]

Yes in the beginplay, that was like that when I created the project, i didn't touch it

[dark drum]

Yea so when the character has spawned, it won't have a controller until its possessed so it would fail. Move it to the on possessed, that should solve the no control issue.

[dark drum]

As for this, I can only assume, it attempts to possess the character on the client before it's actually been created.

[main lake]

Now on the server I can control the character and move around without any issue (but my health red hearts aren't there anymore), and on the client I still am in the floor

[dark drum]

Assuming the data for the hearts is stored on the player controller, its probably being initialized but its been possessed again.

As for the client, I'm not sure other than having the client spawn the character and then possessing it but I'm not sure if thats best practice. It'll probally be best to ask in #multiplayer for that one.

[main lake]

Nope the data for the hearts is stored in my BP_ThirdPersonCharacter

[dark drum]

Show how you handle it.

[dark drum]

How do you set PC Core?

[main lake]

What part ?

[dark drum]

On the 'OnRepHealth' you check if PC Core is valid. How do you set this in the character?

[tepid willow]

Hello, is there an easy way of printing out any struct as a string? I remember seeing a plugin that converts any USTRUCT in JSON format, but I can't recall the name

nvm it's a default UE JSON plugin

[main lake]

The PC_Core has the BP_HUD which is the HUD containing the widget called BP_GameHUD which contains the healthbar that i call the dispatcher for so the Widget can receive that dispatcher

[dark drum]

That doesn't answer the question. How in the character do you set a ref to the PC Core?

[dark drum]

And is that done on begin play? 🙂

[main lake]

yes

[dark drum]

You need to move it to onpossed.

[main lake]

so should I switch that to on posses ?

alright

[dark drum]

Yea, anythng that gets the controller should be moved to the onpossessed.

[worthy jasper]

To be honest you should probably move a lot of that logic to a “run on owning client”

That’s possibly why your server is working but your client isn’t

Get player controller for example will act differently if you call it server side as opposed to client side

[main lake]

I'm kinda confused I'm not gonna lie 😄 Because putting it in "Event On Possess" which is already in PC_Core, it doesn't make sense to save that in a variable in the PC_Core itself 😄

[main lake]

how ?

[dark drum]

Sorry, to clarify, anything that gets the controller on begin play should be moved to the on possessed.

[main lake]

but OnPossessed is only inside PlayerControllers 😄

[frosty heron]

OnPosses runs on server side too

[main lake]

there's no Event on Possess in ThirdPersonCharacter

[frosty heron]

well you generally want to bind input in controller anyway

[worthy jasper]

And TBH anything you expect should be running locally (like binding inputs) after that event that was just posted if follow it up with a run on owning client

[frosty heron]

that runs on server only. For the binding to work, it must be run in the targeted machine

[worthy jasper]

Cause that will only fire server side

So you wanna then fire anything client on its owning client

[maiden wadi]

That was a local function variable that was a copy of the struct.

[main lake]

oh it's just called "Possessed" instead of "On Possess" 😄

[worthy jasper]

And that might be where begin play is tripping you up. Begin play fires server side and client side and it doesn’t look like your making a distinction when your trying to bind input

[main lake]

So like this ?

[frosty heron]

what the heck is that

[worthy jasper]

Your gonna wanna pull off from the new controller, you already have it don’t need to get it again

Event possessed tells you the player controller that possessed it

[main lake]

I understoood nothing 😄

[dark drum]

Yea but as Cold said, it only runs on the server so you'd have to call on owning client. So when that calls you know the server has possessed the pawn and can then call a function on the owning client to add the UI.

[main lake]

oh

So like this ?

[worthy jasper]

There ya go almost

[frosty heron]

I used OnAcknowledgePossesion from controller which is an event that run on client side. On top of that, the pawn is guaranteed to be ready

so that's where I do the binding

[worthy jasper]

Make a function now that “runs on owning client”

And then setup your input, hud ext

[frosty heron]

Don't see why you need to cache or cast

[frosty heron]

I'm soo tired after 13 hours of work but maybe you can try this if you don't want to use OnAcknowledgePossession

On Possesed -> Run on owning client -> Bind there

shouldn't even need to touch the controller

[dark drum]

Do we have access to that in BP?

[frosty heron]

nope

[dark drum]

That explains why I couldn't fine it lol

[frosty heron]

Don't know why tho

a lot of things are not exposed

[dark drum]

Yea, it sounds like it would be useful.

[gentle urchin]

Welcome to unreal

We have all the delegates you need, but we only expose a few 😄

[remote meteor]

its called RecieveControllerChanged 😅

[frosty heron]

😅 good to know

[remote meteor]

i believe its new at ue5 though

dont remember seeing it in 4.27

[maiden wadi]

Probably wasn't. The game instance delegate was there, but it was still C++ only.

[true crater]

Hello Guys, firstly sorry for my bad English.
I want to make a Chaos based choppable tree system. I don't think I can achieve this using Foliage. If I create a tree in the form of BP_Tree instead of Foliage Tool and use them in my open world game, I may experience a significant performance loss. What is the best solution for this?

[maiden wadi]

It's really hard to do in BP only. I did this by subclassing the foliage HISM component in C++ and made a system that spawns a BP to replace HISM instances when they're interacted with.

[dark drum]

When you go to chop a tree instance, you replace it with a BP version.

[dark drum]

I wouldn't say it's hard, just a lot of moving parts so it's easy to forget something lol.

[maiden wadi]

Not sure, I had a reason for needing it in C++. I wanted to use the normal foliage painter to place it in the level.

[dark drum]

I did it through an actor component. Paint as normal but on begin play (or even in the editor) add the special component to the actor it creates (with all the ISM components in it) Just a case of having a list of what BP an instance needs to be replaced with when looking at/interacting with.

[gentle urchin]

Cant you simply replace the hism instance with an Actual™️ actor?

[dark drum]

I never finished the system I was working on but this was the main part. The top branch is for instances that should be swapped out for a BP. The bottom one if for a generic item pickup. I have maps that use static meshes as the key (not totally happy with this) and the actor it should be replaced with. For the pickup, instead of an actor, it uses the item object that should be added to the interactors inventory.

[gentle urchin]

Id prob have that class loaded to avoid async waits but yeah

Probably an already spawned actor tbh

[dark drum]

I used soft references so it wouldn't load 100+ classes even if there not actually in the level.

[gentle urchin]

100+ ouf

[dark drum]

scalability was in mind haha

[gentle urchin]

1 base tree -> swap mesh -> win

[dark drum]

The system I set up was for any instance mesh so it could be a stick, door, tree etc...

[gentle urchin]

Im just animating the ism instance 😆

Very simplistic luckily

Atleast for now

Prob gonna do VAT om them later

[dark drum]

It was pretty cool as NPC could intract with instances as well using the same system and pickup random items off the floor lol.

[gentle urchin]

Whevener inget back to that parked project 😦

Yeah thats how ive made mine aswell

everything is an ism really

Except buildings

[dark drum]

Why not?

[gentle urchin]

So NPC is ISM, which picks up item which is ISM etc etc

[gentle urchin]

Didnt imagine enough of them to care about the overhead i guess

[dark drum]

Just made me think of NPC's carrying NPC's carrying NPC's. 🙃

[gentle urchin]

Tried to keep things data driven aswell

So all new buildings/upgrades/new productions etc is just DT rows

[dark drum]

I need to start doing that more often. I tend to use use Maps where something like a data asset would probally be better.

[maiden wadi]

Use maps of data assets.

[gentle urchin]

DTs of maps of DA

[maiden wadi]

Yeeeeah

[gentle urchin]

Just for the extra indirection /j

I should get into DA's more tho on a serious note

I end up with DTs always and its .. well.. it is what it is i guess

[maiden wadi]

I love DAs.

We started to make everything that is a "thing" into a definition. Which is essentially a DA with a layer or three of inheritance. EG all things inherit from a core DA that has the basics like the name, icons, etc. Then more specific DA child classes for more specific things.

[gentle urchin]

Lyra inspired huh

Currently my DTs point to a Class which is 3 layers of inheritance, covering all scenarios up untill now

[maiden wadi]

Kinda. More datatable inspired. As in inspired not to have datatables, pointing to datatables, pointing to more datatables.

[frosty heron]

I never touched DA but seems like I can't avoid it anymore. How would you describe DA? Is it like a struct with static data?

[gentle urchin]

Untillllll now, were i need a meta item that can be added to other items

[maiden wadi]

DA is more like a static mesh. It's a static asset with static data.

[gentle urchin]

Spawning it to trigger their "use" feels weird and clunky.

[frosty heron]

So like struct that can't be instanced and hold static data?

[maiden wadi]

Kinda I guess. Never associated them with a struct in that way, but same manner.

[gentle urchin]

Soo... a DT 😆

A Map of RowNames and Static data

[maiden wadi]

Much better than a struct in the sense that you pass them around as pointers too, so you're not copying data everywhere.

[gentle urchin]

Can have pointers to DT Rows afaik

[maiden wadi]

Kinda. You can in C++.

[frosty heron]

Some ppl say there are bug associated with DT

[maiden wadi]

You can have a struct that has the datatable and rowname. Kinda the same thing.

[gentle urchin]

And for bp you'd just make a small getter

[frosty heron]

Borderline combative to use DT

[maiden wadi]

What's the bug?

Have never encountered any using DTs. I just find them very rigid and frustrating sometimes.

[frosty heron]

No idea, never come across it but Laura mentioned it multiple times

[plain egret]

Hello everyone im fairly new to unreal and am struggling with a big issue in relation to level streaming, i have a hub with level sequencing to move the camera towards specific places in the hub for settings menu, level select etc. When i load the first level from the hub it changes the camera view of the firstperson character controller to lower than what it is supposed to be(I believe this could be an issue with the camera manager). I believe this issue is coming from the angle and position of the level sequence before switching levels being at a different angle/height.
In the picture the left is the view in game and the right is the actual view we are wanting.
Ignore the high video memory my laptop isnt plugged in right now

[gentle urchin]

Probably BP struct related

[dark drum]

This probably caused by different resolutions for the windows.

[plain egret]

Nah the camera itself is at the top of the first person controller however the camera in the scene is lower than it i will send a photo of that when im able to

[near rapids]

is there a way to make the default capsule component of the character to be horizontal and not vertical?

[grave halo]

Hi guys I have this problem, this code are connected to Event Tick when I die, I want that my character camera follows a spline line to see my body dead from above, the movement works good but the camera never rotate, even if I connect the Along spline rotation or set it manually with set world rotation never rotate. The math logic of the rotation I have here is only a rule of three to gradually rotate it down until it reach the end of the spline but does not influence

[dark drum]

Is the camera set to use control rotation?

[grave halo]

how i know it?

[dark drum]

It's in the settings on the camera. I think it might be use controller yaw and use controller pitch.

[grave halo]

Yeah it was that. I checked all the camera settings but didn't see that, thanks ❤️

[dark drum]

If you want to keep it enabled, you can instead set the control rotation on the controller to update the camera.

[grave halo]

Nice to know, but I don't need it, this only activates when character dies so the game ends

[maiden wadi]

Hard to say initially. I'd assume it's a non trivial issue due to the fact that the capsule is the root. So rotating the capsule would rotate the entire actor, which would likely require some substantial edits in the CMC to account for the difference.

[coarse flame]

4.X had BlueprintType but not 5.X, should I just inherit from Object?

[maiden wadi]

Need context. What doesn't have BlueprintType in 5.X?

[coarse flame]

class BlueprintType does not exist in 5.X documentation

it is for struct exposed to BP

[maiden wadi]

It still exists

[near rapids]

why wouldnt it exist in 5.X anymore

[coarse flame]

I cannot find documentation of it nor can I find it on the menu to choose class to inherit for a new c++ class.

[near rapids]

well usually you put that in the USTRUCT Macro

besides, thats more like a #cpp issue

[coarse flame]

well I just need a way to use struct in Blueprint

[near rapids]

whats the context

just a blueprint struct?

[maiden wadi]

You mark the USTRUCT with the specifier.

[coarse flame]

ah.

I am sending some data from external process via UDP and need to receive it on Unreal side

the specific configuration of bytestream is not set at this point and I want to set everything else then define deserialization method on the struct

[bronze mirage]

dumb question- how does one add a post process blueprint for an animbp? I see that the default mannequin has one but I don't see any place to hook it up. in the character blueprint itself I see a checkbox to disable it but that's it... google is getting me nothing but post process volumes..

[undone bluff]

the 'post process' is just a linked animbp

https://dev.epicgames.com/documentation/en-us/unreal-engine/using-animation-blueprint-linking-in-unreal-engine?application_version=5.3

I think

I haven't actually looked at the new third person template haha

you can specify a post process animbp in the skeletal mesh so maybe they did that

so both ways work

[paper latch]

So I've got a blueprint that takes its world position, and uses that to mask out the "snow" in this material I have here in the screenshot. However, if I have two of said blueprints, it can only pick up one position at a time, as you see in the image. Is there anything I can do to have that mask/world position be added together?

[undone bluff]

the actual skeletal mesh asset, not the skeletal mesh component, to be clear

[bronze mirage]

ok yeah, nice! this is exactly what i was looking for

[idle moat]

I'm working on my character's jump charge. I want it so that when my character is falling before the jump is performed, the charge will be cancelled. My jump charge doesn't seem to be resetting itself?

[lofty rapids]

well you set it to 0.0, then set it again after the branch

so that branch is pretty useless as is

[undone bluff]

IA triggered executes every tick

[idle moat]

I only really know the bare minimum of Programming, a lot this was guess work

[undone bluff]

okay so scrap the tick here

on triggered do your charge increment

(after a branch that checks if the character is falling)

and multiply the amount you add to the charge by delta time but I assume you are already doing that

on the false of the branch you can then reset the charge to 0

elapsed seconds will give you how long the key has been held down, but if you want to cancel the charge if the player leaves the ground at any point then this is the way to go

[idle moat]

Ok Thanks I'll give that a go

[undone bluff]

ah, actually the other way around

is falling true > cancel charge, false > keep charging

[tropic peak]

If I create a BP that loads certain stuff to a data table - will I be able to preview it (the data loaded into the table) in real time when I start simulation?

[undone bluff]

or you can use a 'not boolean' node

[undone bluff]

you mean load a datatable from like a csv?, you can't 'load stuff into it'

[tropic peak]

i can't load a list of actors from a scene?

[undone bluff]

no you cannot store instance references in a table

they are static

you can store asset references and positions (not at runtime)

[tropic peak]

:/

[undone bluff]

I am not sure if you can write to it with some editor utility

but I've seen it done with external software

[tropic peak]

it kinda ruins my plans

[undone bluff]

like a blender scene written to a csv and then imported as a datatable in unreal

and then that data was used to place assets

[tropic peak]

tldr version, open world game, level has "delivery spots" that are placed in the level as actors, I wanted to load the entire list of "delivery spot" actors to a list and randomise one when the delivery is picked up

arrays won't cut it

[undone bluff]

that doesn't actually sound problematic

[tropic peak]

I mean - I want to load the list from the level when the game loads

I don't want to have it in the database as in I don't want to add those manually

[undone bluff]

I don't understand

what's wrong with making a table of potential delivery spot actors and picking a random one to spawn?

[gentle urchin]

At editortime you can

Even at runtime

[undone bluff]

runtime?

[gentle urchin]

Pretty sure yeah

Glorified TMap

Not sure why one would want it at runtime tho

Editortime i can understand

[thin panther]

im confused why an array isn't suitable for a list of delivery spots, given that a TArray is a list

[gentle urchin]

^

No good reason

[dawn gazelle]

This is even one of those times where get all actors of class would probably be good to use 😛

[remote meteor]

TActorRange 😉

[dark drum]

Have a delivery spot manager actor component on the game state then have your delivery spots register themselves in the manager. (Possibly a set to prevent duplicates) When ever you need to get one you can get the manager and get one.

[dark drum]

Never! Lol

[wild sage]

Hi, when I jump and switch characters in my game (possess other pawn), the last character is still in the air, how do I "force physics simulation" on the last character so that he can fall to the ground even if I don't possess him anymore ?

[tropic peak]

manager as in what exactly? a data structure of some sort or a bp?

[dark drum]

Actor component.

[tropic peak]

and how it would be stored?

each delivery point actor has a name and xyz coords

my approach might be flawed. im improvising a lot.

[lofty rapids]

a map of STRING VECTOR if you can

where your names mach up to the xyz

[wild sage]

i found a solution

[dark drum]

I would use a map and use the name of the delivery point as the key and the value being the delivery point actor itself. You can always get its world location from it when you need it.

[tropic peak]

thanks, i cant check that now as im outside but will have a look shirtly

[gentle urchin]

Map requires unique key:-/

[dark drum]

It does but it sounds like he's given them each names. If there are going to be duplicate names, I would just have each of them have a GUID which is used as the key. It sounds like there's just wanting to get them at random so would probally only need the values.

[tropic peak]

basically its a dropoff point for a parcel delicery. there wont be any gps system so the buildings will have their unique addresses

i mean im happy with any solution that just works

[gentle urchin]

Gotcha, ok thats fine then

[dark drum]

If you're going to be giving them unique names anyway, i would just use name as the key then. Gameplay tags might not be a bad option though depending how many you'll have.

[gentle urchin]

PostManager ->RegisterAddress (FName(or Gameplaytag), ActorRef)

[dark drum]

Beat me to it with the gameplay tags lol.

[gentle urchin]

Gameplaytags will be easy to sort

[tropic peak]

ill read about it as soon as i get home

[gentle urchin]

Region.City.Street.Number

Then you can ask for everyone in Region or Region.City

Etc

Using GameplayTag Queries and whatnot

You wont regret it

[white thicket]

Why the landscape is not giving overlap results

https://cdn.discordapp.com/attachments/846520322642411570/1227302705228156999/image.png?ex=6627e9b7&is=661574b7&hm=9cc63662b3be588e2bf64e4df1398b970d4895ab374982cdf52f237d23d705cd&

[lunar sleet]

Cause it’s set to BlockAll

Not overlap

[white thicket]

but then the character will fall through landscape

[lunar sleet]

Exactly

So why you trying to check for overlaps on landscape

[white thicket]

See what I want to make. When the boat comes on landscape instead of water I want to disable input for boat

[lunar sleet]

Don’t use the landscape for that

[white thicket]

otherwise boat will also be controlable on landscape

[lunar sleet]

Put a collision volume on the landscape

[white thicket]

so what should i use?

[white thicket]

But collision would be box or sphere whereas My landscape is curvey

[lunar sleet]

Doesn’t matter, just scale the box up

At some point the floor is too close to the surface for your boat to work anyway

Alternatively, line trace for hits instead of overlap

[white thicket]

yeah That I know For that I would also need the box around the corners as I didn't wanna generate line trace for every frame

[lunar sleet]

Line traces are not expensive

[white thicket]

Really?

[lunar sleet]

You could also make a box overlap, that when the boat gets in, it starts line tracing for precision

[white thicket]

I am making for mobile will it impact too much?

[white thicket]

yeah that i want to say above

[lunar sleet]

Doubt it. The expensive part is drawing the debug on screen, but that doesn’t make it into the game

[white thicket]

Okay I will try Linetracing then

[queen heron]

any point of advice to tell if the player is pressing the opposite move directions or if it let go of the movement buttons?

[dark drum]

Does anyone know what the Field Notify tick box on a variable is? Something to do with broadcasting it's changed. Can't really find any info on how to use it though.

[lunar sleet]

is that on any var?

[tropic peak]

as In tag for each of those?

I'm going to have ~50-100 points

[dark drum]

It looks like it.

[lunar sleet]

weird, I don't see it, let me check more

what's your var type

[gentle urchin]

then the hieriarchy is probably not that deep^^

[dark drum]

I'm in 5.3, i think it was added in 5.2.

[lunar sleet]

floats don't have it on my end

[gentle urchin]

but yes, a tag for each

[lunar sleet]

I'm in 5.4 so I win

[gentle urchin]

identification must be done anyways, so wether you type FNames once, or add Gameplaytags once, it'd be the same job

[lunar sleet]

I don't have it anywhere, what var is yours?

[dark drum]

Oh it's just inside widgets. o.O

[tropic peak]

but that's going to be manual labor for each of those, right

[dark drum]

Yea, is the name actually important?

[lunar sleet]

@dark drum

[tropic peak]

well.. kind of. the player will have to navigate by the name, there will be no markers on the map/gps

[gentle urchin]

FName or GameplayTag is manual labour

GameplayTag is then selectable from a list

FName is not

You can also import a list if you want

avoids typos and human errors

[dark drum]

Yea i've already found that, doesn't really tell me much about how to use it. However I found a topic on UMG View Model that mentions it but from reading through that I have a feeling it's not fully exposed to BP.

[gentle urchin]

I thought it was

atleast the major parts

[lunar sleet]

see if this is worth a damn https://youtu.be/wBWVbdVAR64?si=zCuNB57nQJH5gBO7

[dark drum]

I always forget about this but yea. It's a config file so can be edited externally to make all the names.

[gentle urchin]

guess that's it x)

[dark drum]

Yea, it's the add field value change delegate.

[tropic peak]

wait just to be sure (sorry, it's confusing, I'm pretty new). I will be able to place an actor in my level, give it appropriate tags and that's it?

[dark drum]

Yea, assuming you've set it to register with the manager i mentioned.

[white thicket]

Why this is not showing landscape but showing the water plane I am showing (when I am on landscape)

[dark drum]

Something like this but more specific of a use case and instead of using a name, you use a gameplay tag.

https://youtu.be/RygVokx-mzk

[tropic peak]

awesome, thank you

[lunar sleet]

because the water is being hit first. You can make a custom collision channel where only the landscape is colliding

[white thicket]

I am checking every tick so why it is hiting water plane even when on landscape

[lunar sleet]

draw debug, you're likely still hitting the water volume

[white thicket]

there is no volume. I am just using a plane with water material

[lunar sleet]

or plane

[gentle urchin]

You should too, you know 😄

[lunar sleet]

draw debug, screenshot, show

[dark drum]

Haha, I didn't fancy having to explain how to use gameplay tags. 😛 To be fair, I've used many things for keys in my manager components lol. GUID, Names, Gameplay Tags, even used Int Points, all depends what needs managing. 🙃

[white thicket]

Yeah I found One thing when I start from landscape it always show landscape string even when I go anywhere and same when start from water it always show water plane

[white thicket]

okay wait let me show you

[lunar sleet]

then you might not be tracing every tick, show the rest of the code

[gentle urchin]

INT POINT!? did you push your tiles to a actor manager 😱

[lunar sleet]

I only saw your trace on landscape, willing to bet you're never changing the start/end locations

[white thicket]

It is directly connected with event tick

[dark drum]

It was technically an inventory system so the item position in a grid lol.

[lunar sleet]

🤔 and if you start on water it does water the entire time?

[white thicket]

Yeah

[lunar sleet]

run the game in simulate and see if you can actually see where the line trace draw debug is

[white thicket]

Wait I am showing you a new thing 😂

[lunar sleet]

yeah

why does it say Reference

is that your water plane's name?

[white thicket]

Boat is there but the trace is at player start. I didn't know what i did just now

earlier it was okay

[white thicket]

I think the trace is not attached to the boat

[lunar sleet]

prly cause of the get player pawn

put this on the boat

the code

and just use self for actor location

[frigid summit]

hi guys its been weeks and i still cant figure out how to create blueprint for spawning coin waves like subway could anyone help i just want to know how to implemet number of waves space between coins space between waves and random integer between min and max coins per wave

i even quit unreal because of this

[white thicket]

Finally worked with this

Thanks

[dark drum]

YouTube spawn actors in a grid. That'll get you started.

[frigid summit]

i followed every single youtube video there proplem is they spawn in tiles and i spawn them in open enviroment

i really hoped that i could do it like them

[dark drum]

Well it's a starting point. One piece to the puzzle. So what do you mean by spawn in open enviroment?

[frigid summit]

like this

[dark drum]

So all im seeing is a grid, 3 by X. (Assuming you want them on the tracks)

[frigid summit]

yea its 3 axis on left and right and forward for y

[lofty rapids]

you could just create a spawning function that creates them in a location in a uniform way, then just pass the location to the function it would build out , by wave do you just mean a few in a row ?

[frigid summit]

yea but random int for each wave

[lofty rapids]

wdym random int ? for what ?

[frigid summit]

i want to spawn them in waves

[lofty rapids]

you can do a for loop and just inc a vector a certain amount for each one

[white thicket]

Finally I am feeling like a developer😎

[frigid summit]

yea how do i do this

[lofty rapids]

it's basically just a loop with a step, you have a starting vector, loop x amount of times, and foreach one add to the x or y (whichever your using) keeping a running total as a vector

and just use a variable as a spacer

[frigid summit]

ok you mean for each loop right

[lofty rapids]

no probaby just a normal for loop

you just want them in a straight line ?

what about curves and stuff ?

[frigid summit]

ok and yes

[lofty rapids]

that will be more difficult maths for curves

[frigid summit]

na this is advanced

[lofty rapids]

it's not to bad you just x, y a certain amount you can simulate a curve

but i would start with just spawning them in a row

[dark drum]

This gets you this.

[frigid summit]

thank you so much

[dark drum]

Just to clarify, there's probally hundreds of tutorials that show you how to do this. 😉

[frigid summit]

btw what is size x and size y

[dark drum]

Int Point that's been split. Spacing is a 2d Vector split.

[white thicket]

what I can do so that if the hitting actor is landscape then do this or that

Branch?

[lunar sleet]

prly better to use a cast

[white thicket]

if hitting actor is landscape then true?

[lunar sleet]

I'd do hit actor -> cast to Landscape -> do stuff

on Cast Failed you can cast to your Water bp

if you end up nesting too many casts in a row tho, you may need to switch to an interface or a dispatcher

[white thicket]

Yeah it worked

[white thicket]

No i just wanna cast once

[frigid summit]

now this is what i call real tutorial trust me all the previous tutorials cant do it like this❤️

[marble yew]

is there safe mode or something? UE crashes because exception in construction script

[faint pasture]

You can maybe modify an ini file to load a map that doesn't have that actor on it

[dark drum]

Well if you liked the screenshot, I have some actual tutorials on my YT channel. 😉 The camera system might be up your street with the sort of game you're making.

[untold fossil]

Is it normal that in editor when you stop testing your game the destroy event of characters is not fired?

This seems a bit weird to me, as all other destroy events seem to be fired

What am I missing here?

[frigid summit]

can you give me your channel link

[dark drum]

Click on my face. 🙃

[lunar sleet]

That’s weird 🙃

[gentle urchin]

Damn, that's one nice bridge alright. Good fit, apparently!

[dark drum]

I'm not ashamed to say that went over my head. 😅

[gentle urchin]

2 years ago, on your sandbox channel x)

[dark drum]

Oh that channel lol. I decide to dedicate my time to something more important lol. (UE)

[gentle urchin]

Noted! ;P

[marble yew]

is there something like try/catch or something in BPs? i want to prevent crashing during compile of construction script

[dark drum]

I don't believe so.

[rotund barn]

this should have a simple solution, but im just too dumb and inexperienced. this is a movement system and i can only get it to work when oriented in one of the axis.

[lunar sleet]

Win+shift+S to take snapshots

Why are you using Get instead of just plugging in the action value

[faint pasture]

why are you breaking out those get forward and get right vectors

input to add movement input should be axis value x vector

[dark drum]

You need to connect all 3 of the values from the direction vectors (recombine them into a vector). When you split it, you're only getting the affect in a single direction.

For example, forward could be 0.5 on the x and 0.5 on the y.

[rotund barn]

oh, let me try that way. altough according to someone in yt comments, this is how its supposed to be done because its relative to my camera/vr headset. altough i dont see why it would differ from traditional camera

[dark drum]

I'm not sure what they're talking about. o.O

[rotund barn]

still not fully working, but atleast its now usable as i can walk forward and backwards into any direction, just cant strafe. would you have any idea how to fix that? tho that can be a problem for the future as strafing isnt a big concern for me this early on.

[dark drum]

The right vector is the one that would do strafing. Show your updated setup.

[rotund barn]

tried like this and also connecing the forward vector to both of them (and unlinking the right vector) neither worked

[dark drum]

Does anything happen?

[rotund barn]

nothing aside from what i mentioned previously. now it works going forward or backwards, but strafing doesnt work

[dark drum]

Check you've setup your input context mapping correctly. You might not have set it up for the right key.

[rotund barn]

already checked. other one is in oculus touch (L) thumbstick X-axis, other one is oculus touch (L) thumbstick Y-axis

both of them are axis1D float. and those should be all the relevant settings

[dark drum]

You probably need to use this one and only have one input that handles both forward and right movements. (The IA would need to be set to 2d)

[timber crystal]

guys ezy thing but why it do not work...

I want that when my enemy has 0 live and still collides with me he dont give me dmg

[latent venture]

I am using this in order to move the rotation of an static mesh (which is a door), but it doesn`t rotate, but I can go through the door, does anyone know what is happening exactly?

[maiden wadi]

Debug it. Make sure the boolean is being set with a breakpoint. After that breaks Breakpoint on the apply damage and make sure it's false on the same instance.

[faint pasture]

you're getting forward for both

get right for the strafe one

[rotund barn]

like this? cause now it only goes forward no matter what direction i point the stick

[faint pasture]

Read this code

you're saying "Move in Camera.Forward based on MoveY, also move in Camera.Forward based on MoveX"

when you should move Camera.Right based on MoveX

[dark drum]

Replace the direction vectors of the controller for your cameras direction vectors.

[faint pasture]

Yes this is a better way to do it since it won't try to move up when looking up

[dark drum]

Third Person Template. 😅

[rotund barn]

thank you guys!

[rotund barn]

wait where did you get the input x and y. with the 2d thumbstick axis it wont give me those.

[dark drum]

Right click on the axis value and split, assuming you've set the input action to be 2d.

[latent venture]

aparently if i switch my view to player colision, I could see the doors being rotated as they should, and if i switch back to lit, i see like on player colision, on the perfect rotation, why is this happening and how could i fix this?

[rotund barn]

i must be getting too tired. i just tried splitting it 10 times and didnt give me the option. i probably was not hitting the pin when clicking. my bad

[dark drum]

You need to mark the render state as dirty for the last instance you update in the given tick.

[rotund barn]

thank you so so much, its now working flawlessly

[latent venture]

and how exactly do i do that?

i will find it out

[dark drum]

On the update instance node, there's a tick box called mark render state dirty, tick it on the last instance you update. This will trigger it to update the visuals based on the new transform data you've set.

[latent venture]

like this?

ok

you were right

thank you for helping me, kind sir!

[agile moss]

Can someone do this and send screenshots, pls idk how to do it. Create interface>on begin play call that interface>the receiver prints string. My main problem is getting a valid reference

[dark drum]

Whats the use case? Why an interface?

[main lake]

Like this M

With this setup I can move around with the host but the hearts don't display properly, and for the client still same issue he doesn't spawn and his camera is in the floor ☝️

[latent venture]

but does that array index help ?
because basically when I am generating the room, I am adding the return value into an array, and I thought it would reference only that specific door, what do you think?

[dark drum]

There's no point storing the instance indexes as you can just get the index count from the instance mesh component.

[agile moss]

On each level loaded, it has specific information

Wanted to use casts, but the the reference is the problem

[latent venture]

how?
