blueprint

[pure walrus]

ok thats false i mean obviously

how would we travel ? 😄
its called 3rd newton law

fart in space u'll advance

was it clear ? i can be more precise

[bright frigate]

I'm thinking something so I'll let you know 🙂

[pure walrus]

just wanna make sure u know how to use modulo

so u dont code thing unecessary

[bright frigate]

I'm thinking to divide by the total seconds (the base unit I'm using to track time) divide it by 3600 to get the hour (or just use the hours value) and multiply it by 30 to get 180 degrees, yes? That should work

[bright frigate]

yea that's no problem, in my time manager bluepring I'm using it to get hours/mins etc. so I don't even need to divide by 3600

[pure walrus]

im not sure there is severam path to it, as long as u use modulo to get transformation 29h -> 5h u should be good

[bright frigate]

although problem is, my time is tracked in military format (24 hours) and the degrees will be going to 360 which only corresponds to 12 hours

[pure walrus]

i know there is no air in space
isn't it why they call it space

[bright frigate]

well space is just the emptiness, no air = vacuum

[pure walrus]

again modulo not 24h but 12h

[pure walrus]

thanks xd

mister hoodie think we go to Mars by aiming correctly from the earth !

[bright frigate]

if you really want to be accurate, there is actually some sort of "air" in space, as in, molecules of gas, but the density is ridiculously low

[pure walrus]

u dont need the ground

this is just physics im sorry !

u eject matter u have a force in the opposite direction

i cant justify it except by some adhoc argument like energy conservation

im not debating with u xd

[icy dragon]

But you did it anyway. Stop lying to yourself.

[pure walrus]

alright

one day u will know how spacecraft works hopefully

[fiery glen]

okay, I can't tell if you are arguing about the specific term or saying that spacecraft literally cannot propel themselves in space

[pure walrus]

dont listen to him lol
ofc u have rocket physics in space, u just dont have frictions which makes things actually easier to simulate

[pure walrus]

idk thats the first guy telling me spacecraft cant go to space

i perfectly undestood u
u think we need air to propel spacecrafts

which is the dumbest thing ive heard today but the day just started

u still got time to pb

[tawdry basalt]

a

[pure walrus]

u seem to enjoy speaking about things u dont know

good day anyway !

i see no insults

but ok !

[icy dragon]

Anyfuckingway, you could take the Flying BP template, add some scifi effects, and work your way up from there. The default template isn't that snappy for gameplay purposes, so you should make some adjustments to it.

[pure walrus]

bad advice imo

space physics is simple enough he can do it from scratch

[obtuse herald]

Great weather today

[icy dragon]

Is realism even matter for scifi space games?

[pure walrus]

just making sure your bs doesnt go through xd

imagine saying something true tho

[maiden wadi]

There is a fantastic thing that people came up with in the 90s when the internet started to be a big thing and people were acting just like this. It's called a mute button. Please use it. This place is meant to be constructive.

[fiery glen]

no need to be rude

[pure walrus]

i dont mute anyone

i just demonstrate how stupid they are if necessary

and it was here

since he's misleading another member

[fiery glen]

okay, go have your awesome discord slapfight elsewhere

and prove your awesome victory there

[pure walrus]

i was on my way anyway

no but thats funny saying a spacecraft doesnt work in space

imagine

anyway

[icy dragon]

Check my DM.

[pure walrus]

fine

all good

[bright frigate]

ok I'm not sure why but it's not working as expected.

If my start time is 15, then it should go into the true branch, which it does.
15-12 = 3
3 x -30 = -90 degrees on the X axis. But instead of pointing to the 3, the hand is pointing to 6.

[surreal peak]

Are you taking into account what 0 is pointing at?

[pure walrus]

try manually put -90

[bright frigate]

doing this is pointing it at 4 lol, strange. The start positions of all the hands are 0 (so all are pointing to 12)

[surreal peak]

How is the clock oriented?

[pure walrus]

i see a relative rotation

[surreal peak]

Seems weird

[bright frigate]

Makes sense now because with 0 they are pointing to 1 lol

[pure walrus]

ah

[bright frigate]

that's odd, why are they pointing to 1 at 0 relative rotation? Do I need to deal with pivots yet again?

[pure walrus]

the parent is offset for sure

[bright frigate]

I made sure they were all aligned.... ughhhhhhhh

[surreal peak]

No idea about your hierarchy

[bright frigate]

hmm

[surreal peak]

So can't answer that

[drowsy flame]

Hello, can anyone explain what exactly does
To Direction And Length
(2d vector) Do?seems like it just compares two cordinates with eachother to see which one is bigger?

[bright frigate]

no even after unparenting them, 0 still points at 1

odd

[pure walrus]

then the axis are shift ?

have u tried world rotation ?

world rotation 0 should give u 0h

if not then the axis of the arrows are not aligned

[bright frigate]

lemme see

[surreal peak]

It gives you the length of the vector and the normalized vector (direction)

Or what do you need to know?

[bright frigate]

Still has the 30 degree offset 😂😂

[icy dragon]

Also I think modulo equations will do the same job fine.
Something like
ClockRot = (Hours % 12) * 30

[pure walrus]

perfect !

check the axis on your mesh

[pure walrus]

u better in math than physics

[bright frigate]

It's perfectly fine here 😦

[bright frigate]

Thanks will try

[icy dragon]

Well, I did get poor grade for math at school.

[pure walrus]

when u set world rotation 0 every frame u dont have it straight like that ?

[drowsy flame]

Can you explain what it means?
when I print it it looks like it compares X with Y and if they are the same it returns 1.0 and 1.0
but if x is 2 as big it returns something like 1. and 0.5

so the length is the distance between x and y or what?

[obtuse herald]

My attempt would be (Hours/12 * 360)

[bright frigate]

x 30 is for hours because hour hand has to move 30 degrees to match the number

[obtuse herald]

Which is essential the same

[icy dragon]

That's also an option.

[pure walrus]

his math are correct anyway

he has a axis problem

[bright frigate]

15/12*360 = 450

modulo works properly

[obtuse herald]

ue fixes that automatically

But yeah, modulo is the cleaner way

[pure walrus]

@bright frigate try change the mesh

[bright frigate]

When I was doing doors earlier, anything more than 180 or 360 would absolutely obliterate everything lol it was ridiculously complicated

[pure walrus]

it really should work

[bright frigate]

I'll send you dm with full code hold on

[icy dragon]

Not sure what your DCC tool is, but in Blender, it's easy to forget to apply transforms.

Also how about the clock hand mesh itself on its own?

If it's appear to point upwards in the viewer, in UE, that means the mesh itself is fine.

[pure walrus]

oh ye try ray casting along inner vector

ultimate test to see if it's that or no

[bright frigate]

3ds max

Here's an arrow lol

[pure walrus]

how do u know it is preserved in ue

i meant to battou

u should check

[icy dragon]

Try opening the mesh asset itself in UE.

[bright frigate]

well I didn't mess with anything, I just see if it imports properly. If it doesn't then I redo things in the DCC

[pure walrus]

ue can mess things for u

i hope u know that lol

[bright frigate]

seems fine here

[icy dragon]

Import settings can be screwed up, for one thing.

[bright frigate]

also, I know that if I don't do this set-original-position and just let it increment from pointing at 12, then everything works as expected. It goes from 12 to 1 correctly

[pure walrus]

im confused

i thought the arrow were tilted for relative rotation = 0

[bright frigate]

err scratch that, it starts from 1 as well lol

[pure walrus]

aight

[bright frigate]

so there's a 30 offset for some reason

[pure walrus]

even for world rotation

[icy dragon]

Do you have AddRelativeRotation node got executed after it, by chance?

[pure walrus]

haha

thatd be great

[pure walrus]

can u make sure of that @bright frigate

if yes this is def a mesh pb

no need to look at your bp

[bright frigate]

yup world rotation was also producing same results

[pure walrus]

i would raycast alonf forward/up/right

[bright frigate]

I dunno what I can do with the mesh, it's all set correctly

[icy dragon]

Also another way to do clocks is to make it a skeletal mesh, but that's kind of a different topic.

[pure walrus]

im saying in ue

[bright frigate]

forbidden forest for now 😛

[pure walrus]

thats an overkill

unless u wanna do arrow physics

when u break it

u tried raycast in ue ?
if up is along the arrow tilted with worldrotation =0
i'd just kill myself @bright frigate

[icy dragon]

I'm putting suspect on the timed Event there 🤔

[pure walrus]

i suggested him to try every tick i hope he did

[bright frigate]

ok something is going on with the last node here

[obtuse herald]

disconnect the timer, try the rotation aain

[bright frigate]

I disconnected it and then setting 0 for X was correct

[obtuse herald]

yeah, you're probably not setting current hours when begin play

[bright frigate]

when I reconnected that -30 one, then it gave the offset

[pure walrus]

bad reference?

[bright frigate]

well Sun BP keeps track of hours, mins, secs
So at begin play I'm just pulling the value from there

[pure walrus]

JEEZ

[obtuse herald]

yeah but you have a variable called CurrentHours

and my guess is it is set to 0 when the event first fires

[pure walrus]

u are setting the relative rotation from the relative rotation
idk if it's that i just wouldnt

[obtuse herald]

and when you start with hour 15 (Sun BP) lets say, the branch will run

because 15 =/= 0

then it sets currenthours to 15

and rotates the thing

[pure walrus]

but he tried worldrotation = 0

[bright frigate]

I just tried to see what happens if I reconnect the modulo logic with the final node at the bottom disconnected
and that causes the hand to point to 5 lol

I'm gonna disconnect the timer to make things simpler first

[obtuse herald]

Set CurrentHours to the SunBP's hours on BeginPlay

[bright frigate]

but I'm not using current hours until I get into the timer

[obtuse herald]

yeah

but you get into the timer 0.1 secs later

[icy dragon]

A bit of suggestion, but I prefer going with a single float for total seconds, and do a bunch of non destructive modulo to pull the timestamp out of it.

So for example 30630 seconds would be 08:30:30.

[bright frigate]

now I'm not getting into the timer anymore, it's getting a bit complicated. With this, it should point to 3 on the clock, so why is it pointing to 5 LOL

[pure walrus]

try 0

if 0 doesnt work no need to complicate

[bright frigate]

yeah I have the float too, I can get that. In fact, "hours" comes from modulo operations on the seconds float in the sun bp

[bright frigate]

here's 0 which is correct

[obtuse herald]

try 6

should be -180

[pure walrus]

it should work now

all u have is a math problem finally

nice watch btw :>

[bright frigate]

it's back to it's pointing at 5 again rofl

[icy dragon]

Can the wristwatch die at any moment in the game?

[bright frigate]

haha thanks, I'll show you a real photo of it

[bright frigate]

nope

[obtuse herald]

timer is disconnected?

[bright frigate]

yup

[pure walrus]

how in the hell

90 ?

[obtuse herald]

no other actor runs the Update Time event?

[surreal peak]

You can imagine a Vector like a stick in real life

The Distance is the length of the stick

The Direction is where you are pointing it at

[bright frigate]

nope

this is so weird lol

[obtuse herald]

are you sure?

[icy dragon]

If the watch won't die/misalign at any moment, I think directly getting the time value every tick, without storing it in another variable would work.

[bright frigate]

yup

[obtuse herald]

the watch is broken

[bright frigate]

sure? I was avoiding tick since that's good practice and all

[bright frigate]

it is from the 70s afterall ...

I know that the sun bp time works flawlessly because I'm running the lights off of it too and they run fine. I'm running audio from it, which also run fine

[icy dragon]

Event Tick is fine in this case, since (assuming) you're doing the world time update somewhere else.

[surreal peak]

There is no comparison though, The math behind it is quite simple.
The length of a vector is sqrt(x²+y²+z²) and the direction is just a normalized vector (so a vector of length one), which you usually achieve by diving the vector with it's length (cause, you know, x / x = 1)

[pure walrus]

@bright frigate increment 1 every tick and print the transform while looking at the arrow
so u get the full picture

[obtuse herald]

It is, unless you really really need an update every tick (e.g. renderering, physics)

[bright frigate]

fuggin A look at this

if I use the float instead of the int hours, then the hand is pointing to 6 correctly lol

everything works fine now

lol

wtf unreal

[pure walrus]

why ??

[bright frigate]

wtf

[icy dragon]

Seems like something got lost in truncation

[pure walrus]

ye

[bright frigate]

yeah looks like it

[obtuse herald]

but what

[pure walrus]

nice one

2.99999999 = 2

[bright frigate]

https://tenor.com/view/panda-facepalm-oh-no-worried-anxious-gif-17616305

unreal makes me this panda

also maths

I did great in advanced maths but man simple maths blows my mind off

[pure walrus]

ffs

[bright frigate]

well anyway thanks brudders

[pure walrus]

i still unsure what happened

[bright frigate]

always good to talk, makes the brain go weeeeeeeeee

[pure walrus]

np c;

[bright frigate]

"my code works, I don't know why" 😄

[native willow]

well, its not unreal, that's how cpp converts floats to ints, use round instead

[drowsy flame]

I had to read it 10 times but I finally got it, thanks a lot

Have a very nice day Cedric!

[pure walrus]

it just blindly truncates ?

[icy dragon]

Truncation just omits the decimal numbers in float.

[bright frigate]

frack but the moment I add that last node back in, it adds the 30 degree offset again

so maybe i should use -x30 instead of -30?

[native willow]

well, thats the instruction that it was given, static cast from float to int, truncates the float, even if it is 2.99 it will still result in 2

[icy dragon]

Have you do the same with what's on the timed event?

[pure walrus]

i know what truncation is but here it is int -> float

why does it fuck up like that ?

gonna try

[native willow]

gimme a sec, I need to understand what are you guys doing here

[bright frigate]

I think I need to redo the rest ... the timer code should use the same float now instead of the others because things are being 'lost in translation'

[native willow]

print out the values of current seconds and hours on begin play and compare them

[bright frigate]

here's a refresher

[native willow]

I think the SunBP has a bug with converting from seconds to hours

[bright frigate]

no I think what's happening is, current hours (mins and secs too) aren't being set at begin play

they're being set in the timer

so at the start they are 0

when the values are different, the branch then assigns the new to the old

[pure walrus]

same

[native willow]

print them out and you will know

[bright frigate]

which causes the offset to take place

[bright frigate]

if I print them at begin play they will be 0 since that's the default value

these are local variables in this BP

unless you mean the sun bp's int hours

[native willow]

I do

[bright frigate]

that's printing 17 ... I dunno why, gotta check this out now

clock is set to 15 though (from the seconds float = 54000)

oh wait

haha

ok there are 2 int hours

one is the current hours being set in the bp as the time updates

the other is the one for the UI compass mesh of the sun bp component. Which does not change/update. It's just the slider value

this guy

so I was 'get'ing the wrong one

[pure walrus]

ouch xdd

[native willow]

that's why first thing you do is debug...

then you blame the engine

[pure walrus]

aight thats reassuring

gg

[obtuse herald]

nah nah, always blame the engine first

way easier

[pure walrus]

engine is only wrong half of the time

[bright frigate]

man everytime I do debug first, it's always fine ... reality is that the world is always gonna do the opposite 😄 😄

@native willow are these Floor nodes the culprits?

because even with the correct variable being 'get', it's printing 0 instead of 15

argh

[native willow]

deeeeebuuuuuuug

use print string or breakpoint

[pure walrus]

i dont like those delays

i mean the 1.5sec

why is it there ?

[bright frigate]

this prints correct, so no problems here

but if I print it here in the clock bp, then it prints 0

so I dunno wtf is going on anymore

other than real world timing that somehow beginplay is printing it before the value has been set in the sun bp

If I use Event Tick like this, then it's correct lol

[native willow]

where is this set?

on what event?

[native willow]

Tick fires AFTER the begin play

[bright frigate]

it's in sun bp on tick

[bright frigate]

ok didn't know that I thought tick would be first

[native willow]

here comes your answer

[bright frigate]

but how does that translate to the 30 offset?

should I just remove this timer stuff and use tick

[native willow]

I have no idea, im not following your code

[bright frigate]

ok

[bright frigate]

this did nothing ...

[pure walrus]

u checked mesh visibility and location at runtime ?

[echo salmon]

Hello and sorry for my stupid question , iam trying to understand Cast To . For the sake of this example i have created BP_Item1 BP_Item2 BP_Item1 has a custom event called Hello . If i want to access it from BP_Item2 with Cast To i should do as the follow screenshot ?

[pure walrus]

what could have make them different

dunno your code sorry

so it's not visibility

[pure walrus]

looks good why dont u try instead ?

i always havve an empty level to test those things

[echo salmon]

@pure walrus iam confused because we are already accessing BP_item1 class , why we cant acess its variables and events/functions etc direct after we got the reference ?

[pure walrus]

what if u attach a simple cube to it does it show ?

[pure walrus]

good question

actually u dont

need to cast

if u hover your mouse on the output pin it shows the type

[echo salmon]

What about if we have like 10 items from the BP_item1 class ? And we need to access one exactly ? We should filter it ?

[pure walrus]

resorry no u dont need to cast

[maiden wadi]

You don't need to cast, but you still should cast or check IsValid.

[pure walrus]

ye either u keep track of them with indexes or u put them as a variable instead

and set the reference

[echo salmon]

So basically if i have lets say 2 BP_actors (two cubes) and i want to access each other i have to first get its class and then cast to the actual BP_actor1 . So its a required that we have to Get All Actors from class if we need communication between two actors .

[pure walrus]

i would use reference instead it's more safe

i never used that node personally

[maiden wadi]

What is the use case for the two cubes? Are they placed in level and just need a reference to each other? If so, put an instance editable variable of the type, and set them in the level on the details panel.

[pure walrus]

and event dispatcher if u need every instance to respond the same way

[echo salmon]

Yeah , iam just trying to understand Cast to , iam not searching for the best solution . Thank you for ur kind help

[pure walrus]

hmm

can u change the snowman mesh easily ?

so u are sure it's not a custom mesh/material problem

oh

thats a difference between them true

worth a check

but u said the cube is visible normally ?

if u attached it to the mesh then rotation must be good

ye

ah

ok

ig u checked on wireframe

[maiden wadi]

@echo salmon Casting is much simpler when you understand the data you're handling. The blue variables like that are called Pointers. These variables do little more than hold a memory address in them. When you create a new object instance, that instance gets created and is placed in memory. Pointers point at that memory location. This is done to avoid copying around the object everywhere. Pointers by default are empty, this is why if you place a new one in a class and don't Set it, it'll be invalid. But like your GetAllActorsOfClass, this function iterates over all actors in the level, checks if they're that type or something that inherits from that type, creates a memory pointer and passes those back as an array.

Basic lesson over, the reason it is important to know what memory pointers are is because when you cast, you're telling the compiler what you expect this pointer to point to. This is a safety feature to keep you from accessing random pieces of memory. Say you create Item1, this gets stored at memory address 123412345. When you cast this pointer, you're not actually changing that. The pointer will still point to the same spot, you are simply changing what you expect to get from that memory location. If Item1 inherits from Actor, it also inherits from UObject. So you can successfully point to the same object stored at 123412345 location whether you cast it to Object, Actor, or Item1. If you try to cast to Character, the cast will fail, because Item1 has no inheritance chain to Character.

[echo salmon]

@maiden wadi thank you so much for you in depth answer about Cast To . Make sense now.

[pure walrus]

show collision ?

[maiden wadi]

Best way I started learning Casting personally, was to start thinking of it as TreatAs instead.

[pure walrus]

i see them as policeman checking ids

[fiery glen]

that's a good way of thinking about it

[pure walrus]

thanks

but it is on the visible one ?
then the mesh went byebye

so the cube would be floating here in the capsule?

if yes i would say the mesh has a problem not the component

can u set snowman mesh at runtime ?

i think u gotta check if the cube is attached to the mesh by shifting the mesh, it should shift the cube too
if it does that means the mesh is here but has no geometry somehow
if it doesnt move it may have been destroyed

lol

thats weird..

nice!

u are just setting the location here

no matter the shenanigans u do this should'nt tilt it

[hexed inlet]

Ahhh, I see. I missed that.. and almost missed your reply. TY.

[dawn gazelle]

I know you asked this a while ago, but I thought I'd have a crack at it...

[bright frigate]

Hey thanks, I just figured out the answer myself moments before you posted this

It was my logic

the rotator -30 = new rotator is flawed because it just deducts the angle regardless

the yellow highlighted part is the one that I should have done

because that properly takes care of the values on whether to move it or not

[pure walrus]

i said it lol

[bright frigate]

I didn't understand what you meant haha

but I think when you said it, this did flash in my brain for a moment but there were so many things going on that it just slipped at the time 😄

[pure walrus]

we did said a lot of things xd oh well u good to go now

[bright frigate]

don't worry I'll probably think of something else that will require brain frying hahaah

[undone otter]

Hey, does anyone know why my Blendspace 2D is not playing turning animations, it does IDLE/Forward/Fast but even though I have all the animations setup for left turn and such. It does not register the turns when the animation is played. I have setup the blueprint and setup the direction and speed variables and put them into the statemachine. It would seem they are not working. Anyone have any ideas what could be causing it.

[pure walrus]

does it show in editor ?

[undone otter]

Sorry the animation is not playing but AI character is turning

It swimming forward, but when it turns it does not show the turning animations.

I am using EQS system for navigation

[pure walrus]

so does it happen only at runtime or also in the anim blueprint (assuming thats what u use)

[undone otter]

At run time

the animation blendspace is working fine in the editor, its when run time happens, they don't play animation when turning,

[pure walrus]

and u have debug the variable u feed

[undone otter]

Yes, I have check to see if getting direction and it is

I have printing everytime it turns

[pure walrus]

have u check with a constant value to be sure its not a ref pb

[undone otter]

letting me know the values and they are between -180 and 180

not sure what constant value your refering too

[pure walrus]

value that ensures u dont get a static state

[pure walrus]

u only set the speed in begin play

[undone otter]

I swapped them around earlier

to see if that was problem

from Event blueprint begin play and Event update animation,

Swapping them around did not fix the problem

[pure walrus]

ok

the is valid should be in update too

oh u swapped the event

[zinc blade]

How would I be able to get a live reference of a spawned enemy to update its own Health bar Widget UI? Cause this is what I did but it looks and seems wrong.

[undone otter]

Yeah i have tried lots of things to see if it fixes or breaks it more, see if i can find problem, but I clearly missing something

[pure walrus]

https://www.youtube.com/watch?v=sEcoWGrF1Hg

[pure walrus]

so by constant values i meant unplugging direction and speed and put big numbers in it
but i guess u already tried

[zinc blade]

so you mean I could use EventDispatchers on my Widget Blueprint?

[pure walrus]

why dont u put the widget as a variable of each ai ?

if thats the pb

or/and vice-verca

[zinc blade]

I did...?

[pure walrus]

then whats your matter exactly ?

[obtuse herald]

WidgetComponent =/= WidgetReference

[pure walrus]

i still dont get the issue :/

oh ok

[zinc blade]

spawned enemies have the same UI; even when their percentage values decrement due to damage dealt
it updates the same; loses some gains some

Hello. I created a project in 4.27 but have to use a plugin which is only working for 4.26. Now when I switch engine versions the map can't be loaded anymore. Is there a way to convert the map to another engine version or am I stuck in 4.27?

[native willow]

whats the map?

[pure walrus]

with the function u used so far

[pure walrus]

this ^

[light token]

It's my game mao

map

[native willow]

variable?

[light token]

No the project map.

With all positions and stuff in it

[native willow]

what is the project map? im confused

oh, you mean a world asset right?

[light token]

yes

[native willow]

jeez

[light token]

sorry, noob here

[native willow]

was confused with TMap container

[zinc blade]

here for reference sorry.
it can be too hard for me to explain it in words

[pure walrus]

@zinc blade this is the way to go with an event or a function
be aware that u set the type to "Widget" and not anything else
(im just paraphrasingg)

[light token]

Is there a way I can use that world asset in 4.26?

[native willow]

switch the engine version, I don't get the issue

[light token]

then it complains my world asset was created in a newer version of the engine

[obtuse herald]

Add a variable to your WidgetBP of <YourEnemy> reference. In your enemy, OnBeginPlay => get your Widget reference, and set it's enemy variable to self.

[native willow]

try to migrate it

[obtuse herald]

now you can use the bind function inside the widget editor to update accordingly

[light token]

Ok will try

Thanks a lot

Failed to open map file. This is most likely because the map was saved with a newer version of the engine.

This is the error I get

[pure walrus]

i would need your bp to understand more but i know its wrong to use "get actor of class"
u should call the widget function/event from the owner AI class
so u are sure everything is separated

[zinc blade]

so like this? @pure walrus @obtuse herald (EnemyBP)

and then like this (WidgetBP)

[pure walrus]

toyb was right your widget variable is a widget component

it should be a widget ref

[obtuse herald]

yes

now try it

[zinc blade]

I think it is a widget ref. Is this right? I set its Widget Class

[obtuse herald]

GetWidget retunrs the widget reference it currently draws

[pure walrus]

aight

[zinc blade]

THANKS

OMG

[pure walrus]

haha

[zinc blade]

thanks you guys @obtuse herald @pure walrus

[obtuse herald]

you're welcome

[pure walrus]

ez

@obtuse herald im unsure the difference between the 2 tho

[obtuse herald]

The WidgetComponent draws a widget inside 3D Space (often used for VR). The WidgetComponent thus creates it's widget but instead of adding it to the viewport it draws it inside the 3D space.

[zinc blade]

here's the result~ thanks again, so much.

[obtuse herald]

(technically it draws the widget onto a rendertarget and that gets drawn onto a plane)

[pure walrus]

can we say its a widget + scenecomponent ?

[zinc blade]

ow whoops I always forget; my mic was on

[obtuse herald]

yeah thats probably good enough

[pure walrus]

hm never did 3d widget

[pure walrus]

aight nice c:

Hi, I want my mouse cursor to snap to a world location on screen. But the cursor is always offset from it's target location. Any idea what I am doing wrong?

I notice the offset varies when rescaling my window

but I am kind off lost on how to take that into consideration

[obtuse herald]

try inputing a player controller

[formal wren]

yeah, already did that 😄

wasn't the cause

I uncollapsed my helper function to show my logic and the node was disconnected by that

[pure walrus]

isnt it the ceil part ? or it's a big offset

[obtuse herald]

I don't think we are talking about a 1px offset

[pure walrus]

that answer why they are int

ok

wait

[pure walrus]

arent they dpi ?

nvm

[odd ember]

it should be scaled by DPI

there's a function for this afaik

[waxen sorrel]

isn't possible to keep stored an array of components created in a BP ?

without the need of recreate these on the construct

[faint pasture]

You need to instantiate components. What are you trying to do?

[waxen sorrel]

I'm creating instance components

[fallen glade]

Can I use timers dynamically? Like having an array of timers doing the same thing with different parameters?

[waxen sorrel]

Inside a BP that are stored into a BP Array of StaticMeshComponents

at restart the editor the array is there as is visible

but the components are null

[faint pasture]

When are you adding them?

Hi all,
Attempting to get all Data Assets that derive from a C++ Type using the Asset Editor Subsystem "GetAssetsByClass" with "Search Sub Classes" set to true - what Class Name am I supposed to be entering? I've tried various formats (full c++ class name, without the U, with a /Script/MODULENAME.ClassName) but still not getting any results.

This is just in an Editor Utility Widget. Any help would be greatly appreciated

Hello. I have a simple logic in the level blueprint that allows me to activate and manipulate level sequences using certain keys.

However, since I am making an open-world game I would like to manipulate and activate this only in certain trigger boxes. Also, in the best-case scenario, I would have different children mechanics applied for different cases and level sequences. I would need better control.

How to translate the logic from the level blueprint to a separate blueprint
What is the easiest way to translate this level blueprint mechanic to apply in certain trigger boxes for example or in certain cases? Thanks in advance!

I tried to copy and paste the logic from the level BP to another newly created BP but nothing happens

[brazen pike]

that is super hard to read, any chance you can paste it into blueprintue.com and post the link here?

[vagrant flicker]

Yes, I am sorry. Didn't know that exist 😄 https://blueprintue.com/blueprint/tdlo4f9c/

[obtuse herald]

https://blueprintue.com/blueprint/tdlo4f9c/

I found it

[vagrant flicker]

Basically, I need to translate this into a separate BP I think and activate it only in certain triggers on my map... But have no idea how to do it

[round panther]

So im trying to make a really basic character changer and my problem is that when i change the animations, its not all the animations its just the idle animation does anyone know if theres a node i can use?

[vagrant flicker]

And as my game grows I sense there would be a smarter way to do this kind of mechanics instead of accessing them all through my level BP

[zealous meteor]

Hi, so I have been trying to make car controller similar to rocket league but I cant make it work. Has anyone an already set up car or maybe someone can help me make the controller arcady?

[brazen pike]

Yeah so that'll be because a BP can't access the same things a level BP can. This is one of those classic youtube tutorials where they tell you the easiest way of doing something to get the shortest video length, rather than the best way of doing something. There's quite a bit you'll want to do and learn, so it would actually take me a while to explain it all. Have a look at some more tutorials of how to do individual things first, then you'll slowly get a hang of all the different techniques to put them together.

So just some random concepts I'll through out are gonna be key inputs in project settings, trigger boxes, casting and object references. You're going to want to use those, if you just really want to do this right now

But I would recommend watching some more tutorials first

[faint pasture]

Level BP I'd ok for very level-specific things (tower falling in battlefield, etc). But I would make BPs for more generic things like buttons opening doors. You can make a door BP and button BP and link them up by tag.

On button press, Button looks for Door that matches it's tag and opens it.

Get actor of class with tag.

[vagrant flicker]

Thank you very much guys. I searched some tutorials for this kind of scenario, but wasn't able to find ones.
So, I need to make a generic BP and cast the sequence to the generic BP and transfer logic there?

It's still messy in my head. Maybe if you suggest me some particular tutorial for this cases.

[obtuse herald]

https://www.youtube.com/watch?v=6IOgkWv1lEY

[brazen pike]

Yeah, you also should go to 'project settings', then go to 'Inputs' and add some custom inputs. Little bit easier than doing a key input every single time. It's also better when you get a little further down the line

[vagrant flicker]

Oh thanks! I am going to hit that books now 😛

[zealous meteor]

Can someone help?

[gusty shuttle]

@zealous meteor You can create a new project and select the vehicle option for the starting assets

Assuming you didn't already know that

[zealous meteor]

I want to make my own car

[gusty shuttle]

But that vehicle controller might steer you in the right direction

Well you gotta learn from something, might as well learn from the base line vehicle pawn they provide. You don't have to use it, but learn from it

On my end, I'm trying to figure out how to get the text in my enum to a string or text variable haha

[atomic salmon]

@zealous meteor ask in #legacy-physics, there is quite some expertise and similar ongoing projects

[obtuse herald]

tostring

[gusty shuttle]

Aye, it just returns the number that enum was set to. All good, ima run a ForEachLoop and get the index number

Unless there is a diff way to go about it

[unique wyvern]

When you have a for each looping through a class struct array variable, are each of the elements passed by value or reference

[gusty shuttle]

@unique wyvern Are you talking to me or someone else?

[unique wyvern]

asking a seperate q

[obtuse herald]

there are 2 functions, they look the same but they return diffrent things

[obtuse herald]

you want this one

<@&213101288538374145>

[gusty shuttle]

My god...you're right @obtuse herald That's exactly what I needed! Thanks!

[torn kettle]

:no_entry_sign: Klavs#8135 was banned.

[gusty shuttle]

Dude, that just unlocks so much more potential haha. Why did I not know that?

[obtuse herald]

you're welocme

[zealous meteor]

Thanks

[obtuse herald]

for each loop passes you a copy

when you double-click the node, you can see it for yourself

[unique wyvern]

aight ty

[faint pasture]

You need to first learn what casting is. That's not a sentence.

[obtuse herald]

(references always have these diamond shaped pins)

[burnt trench]

How is this an infinite loop?

Initially the for loop is fired at beginplay btw

[maiden wadi]

Completed, start loop again.

[obtuse herald]

Delay nodes don't delay the ForEachLoop

[maiden wadi]

It's not that. WasKilled is never set in the loop.

[wise mantle]

i got an actor i wanna turn visibility on, when its not on screen. i tried this setup that i found online. it gets the location of the actor and converts it into a 2d point on your screen. with this blueprint, the game knows when i dont look at the actor. problem is that, when i look at the actor, but i place a wall inbetween, the game still thinks the actor is on the screen. how can i check whether theres an occluding object in the way?

[burnt trench]

ohh the delay node doesnt, I see. How can I handle this situation then

[maiden wadi]

Wait. No. I confused myself. I thought those were checking that the same.

But yeah. If you call that with WasKilled false, it'll infinite loop.

[obtuse herald]

I'm sure DoOnce can help

DoOnce -> Play Montage -> Delay -> Reset

It would actually still infinity loop

[burnt trench]

inside for loop?

yeahh

[obtuse herald]

What do you want to do?

Play an animation after the other?

[burnt trench]

yes

in a loop from the array

until the AI was killed

[obtuse herald]

aaaaa connect the get node with the index

[obtuse herald]

I don't know why you wanna do this but you can always line trace it and see if there is an occlusion, or even better, use the 'WasRecentlyRenderd' node

wait no the node aint work because the visibility is off when you're cehcking thus no render recently

[wise mantle]

yea exactly xD. but i can try some line tracing

but how will i got about doing that. can i shoot a line from the camera to the actor, and then check if the line hits something on the way? i havent worked too much with tracing

[obtuse herald]

Yeah

[vagrant flicker]

Okey guuuys, so fast question again if you have 2 minutes.

I made the transfer from the level BP to generic BP which holds only the needed information for the game mechanic.

I set ActorBeginOverlap to play the function, but I had a bump there too. So basically everytime I enter the trigger the sequence will play only 1 time. I need when I enter the trigger NOT to activate the BP but provide me the opportunity to play it on input keys as it was in the level bp.

https://blueprintue.com/blueprint/qduj2bfi/

Any advice is highly appreciated!

[obtuse herald]

It only checks the origion of the actor tho, so if it's large things might not worke out perfectly.

[burnt trench]

gotchya. I was making a new macro for a for each loop with delay built in as a solution haha

[obtuse herald]

that ofc works aswell

[wise mantle]

ok. with the location to screen node, i just added multiple points to hit, so its withing the threshold-ish, if that even makes sense. no matter what, i think the trace solution might work. ill be back

[wise mantle]

this setup seems to be going through walls if im correct. should i use another linetrace function?

[faint pasture]

Uh, what exactly are you trying to do here?

[wise mantle]

@faint pasture this

[faint pasture]

Trace to your target actor by channel

That trace you are showing there is tracing from camera location to plane, and only hitting the plane. That doesn't make any sense

[wise mantle]

so you use trace by channel if you wanna include other object in the trace too?

if that makes sense

[faint pasture]

Yes. Trace by channel traces from start going to end point, and tells you if it hit anything the blocks that channel. The channel you probably want to use is visibility, one of the built-in ones

Like you could have your walls block visibility but not your glass

[wise mantle]

ok thanks. i got a bit confused with all the trace functions

[faint pasture]

But remember it only traces to a point. Depending on what the actor is, its location might not be where you want to trace two. If it's a character, you probably want to move the point up to like head level instead of tracing toward their feet

[wise mantle]

ok. in this case, its just a static actor

or else you would plus with a vector3?

[tiny vale]

How would i go about doing a 3d widget that stays the same size even if ur distant from it?!

[obtuse herald]

try it like this

this is the function

[faint pasture]

I think on the widget component you should have an option for screen space

That is, if it's a widget component attached to an actor, not a widget added to the viewport

[obtuse herald]

Note that Screen space widgets will never get occluded

[tiny vale]

any idea why it doesnt show on the edit viewport?

[obtuse herald]

cause it's screen space

[tiny vale]

its working but its not on the position i want am i doing anything wrong on the actual widget? ** **

[sacred elm]

So I'm trying to make a simple AI character that walks on the x-axis towards my player, but it won't move with physics enabled. And I need that to perform attacks on it that knock it back. This is what I have for its movement now:

it's running on event tick

[spark steppe]

there seems to be a lot of issues in that node setup

[sacred elm]

yeah, I'm just guessing at this point T_T

[spark steppe]

unless it should really only working when on the positive side of the x axis

[obtuse herald]

dangerous

[sacred elm]

for right now, yes

is there a better way to do this?

because it's getting frustrating

[spark steppe]

if yours is not working, yea sure theres a better one 😄

the one which works

[sacred elm]

lmao

[spark steppe]

or use nearly equal zero (which is the same but a bit more compact) 😛

and you might want to negate the output

as it actually would only move when it's at 0

[sacred elm]

oh, I wanted it to basically stop if it was in the air

like stop moving left/right

[spark steppe]

oh i see

but then use the z-axis (which is the up axis in unreal)

[obtuse herald]

that would be Z axixs then

[sacred elm]

omfg

I'm so dumb

[spark steppe]

nah, beginner mistakes

and it would really only work with flat terrain then, so you may wont to improve later on this

[sacred elm]

okay, so it stopped moving when it's hit up. But now it won't move to the side lmao

[obtuse herald]

we've been all at the point were we thought that y axis would be up/down because we all've played minecraft before

[spark steppe]

could use a line trace to detect the distance to ground

[sacred elm]

yeah

is ai movement normally this hard?

for like zero reason?

[spark steppe]

thats not even ai movement

[obtuse herald]

no, normally you use a character movement component

and nav meshs and stuff

[sacred elm]

I've got it on an actor because add movement input wasn't working

and I don't need like crouch or sprint or anything on it

[obtuse herald]

If it works it works

[spark steppe]

well, those can all be disabled in character movement component

[sacred elm]

it doesn't lmao

[obtuse herald]

but it's not the usual way

[spark steppe]

just be aware that there are other methods that are usually used to let AI wander around

[sacred elm]

I guess I'm just trying to figure out why the character refuses to move lol

[obtuse herald]

are the forces enough?

also you're just accelerating the collison capsule

[sacred elm]

I guess not? I mean i've got it at 1000

isn't that all I needed to move?

[obtuse herald]

just add a zero an see if it does the job

[obtuse herald]

depends, if your mesh is not attached to the capsule collision then it wont move

[tiny vale]

does anyone know what am i doing wrong?

[sacred elm]

oh it is attached. And the zero didn't work. It just straight up will not move side to side

[obtuse herald]

that looks good, where is the problem?

[sacred elm]

I was gonna say, that's great, dude. Very visible

[tiny vale]

i can't see the item tho after a long distance

only the widget

[obtuse herald]

debug print it what the branch executes

[sacred elm]

I mean the widget was covering it up was it not?

[obtuse herald]

thats what screen space does

[sacred elm]

oop. that's what it is. it's just not adding any force

[obtuse herald]

hahaha

[tidal marlin]

Hello. Who, by any chance, knows how to get the get global settings node?

[obtuse herald]

This?

[tidal marlin]

no

[sacred elm]

okay, it's working now. Thank you guys so much ♥

[obtuse herald]

yeah then I don't know what you mean

[obtuse herald]

you're welcome

[tiny vale]

im trying to recreate something like this , now i think they are not using screen space

[obtuse herald]

They probably are, just the pivot of the widgets are at the arrow-head

[faint pasture]

That's in screen space for sure

[fresh charm]

yoo

somebody know why my line traverse this object ?

[wise mantle]

ok i finally got it working exactly as i wanted xD. i had some trouble with multiple objects to trace to, but it finally works! thanks for the help @obtuse herald and @faint pasture 😄

[pure walrus]

gonna guess collision is set to physics only or no collision

[tawdry valley]

How does the Combine Rotators work

I thought it would add the two together but it doesn't seem to work

[pure walrus]

order matters

[pure walrus]

try switch

[sacred elm]

another problem :)

[sacred elm]

How do I reference the blocking volume I'm using for the ground? Like if my collision capsule is touching the ground, I wanna do _____

[pure walrus]

best to check at runtime

[fresh charm]

wdym

you want print if object have colision ?

[pure walrus]

print collision object type

[fresh charm]

ok

[pure walrus]

to be sure

[pure walrus]

visible in ray tracing ?

[fresh charm]

ok wait

i send you some pics in DM

its weird

[faint pasture]

If it's not hitting then that object isn't blocking whatever channel you're tracing against

[pure walrus]

i think he was tracing against self

[fresh charm]

yeah

just uncheck

[plush swallow]

is it possible to store an object class in an array instead of its reference in BPs?

or actually just a class object variable instead of a reference

lets say i spawn an actor but the actor instance variables changes throughout the game and i want to save it as a variable with all the variables but then i delete the actor and i want to spawn it again with all its same variables it had when i saved it

[maiden wadi]

Oof. The Savegame wall.

[plush swallow]

i meant storing the object as it is

if i spawn a class of it all of the variables will be set to default

[maiden wadi]

Usually you just store what variables you need to save somewhere. Either on another object or in a savegame object, then reset them after creating the new object.

[plush swallow]

so u have to manually store the instance variables in a different object then set them all of them when u spawn a new actor?

kinda seems too tedius especially if u want to save different classes of objects

[maiden wadi]

Are you talking about saving things in the same game, or saving things, closing the game, starting the game and loading all state back?

[plush swallow]

saving things in the same game
lets say i spawn an actor instance with hp 50 but then the instance gets hit and has 25 now
lets say i want to store that instance that has the variable hp 25 and then i want to clone the instance so now theres 2 of them with 25 hp

basically saving the actor class with all of its variables

[maiden wadi]

Not saving. Creating a new one and copying variables.

[plush swallow]

so i have to get set for every variable the instance had?

[maiden wadi]

Sure. Structs will help with that. So will a decent hierarchy of objects if they're going to get complex.

[plush swallow]

but what if i want to store different class objects in the same array

or do i have to use c++ for that

[maiden wadi]

Lower level class pointers.

C++ won't help much with that. It has the same restrictions. If you want a lot of different types in the same array, they need to inherit from a common place and be stored as that type.

[earnest tangle]

inb4 voidpointers

[spark steppe]

or byte arrays

if you want to save objects, use a 3rd party plugin which allows for object serialization

[plush swallow]

i mean they are all actors but they would be inherited child actors

[earnest tangle]

...but yeah those might be signs of poor architecture

...huh? 🤔

lol yeah

it sounds like you'd want an event dispatcher?

[maiden wadi]

Also, you've been on Youtube too much, that is not what casting means to do.

[maiden wadi]

@trim matrix

Casting doesn't actually have anything to do with communication. It just tries to allow you to use a pointer to call a specific function on an object.

Calling the function is communication. Calling a function is making a phone call. Casting is knowing when to use the country or international code.

[spark steppe]

casting is like calling someone and asking him if he identifies as Dog

@trim matrix Confirm that the idle breaker index is getting set to the random number as you think.

mmmh

where exactly cause I think I might of broken something

the issue is here???

@faint pasture

@faint pasture #blueprint message

[tiny vale]

i have a question that i always got confused at, how do i set that uplink widget texture thats blue to be like red for example if its the other team's actor and the material but thats a stretch

on a multiplayer game

[faint pasture]

Do you already have the functionality to change the color? Not to drive the change, but the raw functionality?

Like a dynamic material or widget tint or whatever.

[tiny vale]

yea

a Material Instance

that has a color parameter

[faint pasture]

If you do, then you need to come up with some function to drive it. If you already have a Team variable living somewhere, then use that.

Just give the actor a Team. Then if Actor team = local player team, set it blue. Other way around, set it red.

[trim matrix]

@faint pasture did you watch the vid

[spark steppe]

https://tenor.com/view/disco-dance-dance-dancing-gif-10516145

[faint pasture]

No I'm on a phone and can't see s***. But if you can confirm that the index value being read in the anim BP is correctly being randomized the problem is going to be something else past that.

[spark steppe]

are the animations set to loop?

[tiny vale]

but how do i set it blue if its a world widget

[faint pasture]

The widget sets itself blue

[tiny vale]

but won't it be blue for the other team also?

[faint pasture]

It's a widget component on a world actor rightm

No, you don't replicate the color. You just replicate the team the widget belongs to

[trim matrix]

@faint pasture

[faint pasture]

It does that work as expected?.

Test it at the last place that variable is used, in the animation blueprint. If the integers random as expected, then that's not your problem.

[trim matrix]

yes the number keeps changing

but the animation wont play

unless its 0

so the problem is not there I think

Its somewhere else

what about here?

[faint pasture]

Are you sure the other animations plugged into that player or even valid?

[trim matrix]

I think yeah

this is so that the character can walk or run even if the idle breaker animation is playing

[spark steppe]

are they set to LOOP?

or play when becoming relevant

does anything play if the index is not 0, like the first one?

[faint pasture]

Yeah plug the first animation into all three sockets and see if it works for any random number

[trim matrix]

ok

so for some reason

I remembered my friend put that value

and now it works

can someone explain to me how

[spark steppe]

you sure it wasnt your dog?

or you?

[spark steppe]

what transition is that even? in or out of the idle breaker?

[trim matrix]

😏

[trim matrix]

lol

bro I slept 5 hours

idk wtf is going on

well since im already in the animation

idle breaker time remaining = means the next time before the next animation

so since the time remaining is currently 0

0 is smaller than 0.2

idk if I got that right

@faint pasture you get it?

[spark steppe]

yea 0 is smaller than 0.2

all the other things, not sure about that 😄

[trim matrix]

jeez

I need to stop sleeping so late

lirely have a headache rn

[tiny vale]

is this bad code for setting up different color for players based on team?

Also it only works with a keyboard input for some reason, if not it gets called 3 times

[sacred minnow]

hello everyone i have a question im trying to make a button that changes the resolution, i dont know to explain this very well but, everytime i click the button it changes to a higher resolution, then loops back to lower resolution

[spark steppe]

that sounds awful

[pure walrus]

id do a checkbox with 2 different res image

[sacred minnow]

oh sorry i said this completely wrong

its to toggle between fullscreen and windowed

[pure walrus]

u mean size

ok

i would still use a checkbox with 2 images

[spark steppe]

you could also make a button that picks a random resolution 😄

i would just make a combo box to switch between the modes

[pure walrus]

or put a transparent border and collapsed it to have the other fullscreen

in a horizontal/vertical box

[sacred minnow]

i made this at it seems to work

[pure walrus]

u meant the res of the game

okay xd

well good

[spark steppe]

isn't there also windowed fullscreen?

[sacred minnow]

oh yes

but how do i make a loop for the 3 modes?

flip flop is only for 2

[spark steppe]

get the current mode as enum, switch on that

and offset them all by one

e.g. if it's fullscreen set it to windowed fullscreen

if i's windowed fullscreen set it to windowed

if it's windowed set it to fullscreen

or use a enum select node, to specify the new enum value

which is the compacter solution

[last walrus]

what event is called after ALL scene is prepared for work?
in multiplayer looks like players are not created instantly after the "begin play"

[spark steppe]

beginplay

[last walrus]

look closely
it's already called in beginplay

[faint pasture]

Learn to use an enum driven State machine, once you do it, there's no going back.

[spark steppe]

yea, but beginPlay can fire in arbitrary order, thats why i removed that comment

[last walrus]

and... how do I make it to execute after everything is done? maybe theres another function saying "hey dude, game is ready, you can play"

[spark steppe]

maybe beginplay of the level blueprint? 🤷

or is your event already in the level blueprint?

[last walrus]

I'll try this
1 sec

[spark steppe]

also don't move your whole logic

just add an customEvent to your game master manager actor

[last walrus]

nah
doesnt work

[spark steppe]

and call it from the level blueprint

hmm, how many players should be there?

[last walrus]

in this example - 1 (server is not counted cuz it doesnt have a possessed pawn)

the window in right - player camera

if I make this screenshot right after the launch - screen is black - no player yet

[spark steppe]

is the first player client also the server?

[last walrus]

no

[maiden wadi]

@last walrus I know this isn't exactly perfectly helpful, but realistically there are no perfect events for something like that. Pretty much all events are considered unsafe to rely on for order in multiplayer. This is one of the biggest reasons that C++ is so highly useful in Multiplayer coding. For instance it would be very easy to use PlayerPawn's Client side Possessed version to send an RPC to server, telling server that client is ready after possession. Store that character in GameState as an array or something. On number reached, do game start code. In blueprint, you're going to end up relying on the locally controlled pawn's beginplay to do this same thing, not quite as nice in the end. Ends up with networking checks and fusses up what should generally be used for state setup for actors becoming relevant.

[last walrus]

looks like this is the only solution
I thought about it too but relying on some variables/other actors... Ill think of other solutions, without calling after all actors are spwaned

[undone otter]

is it true you can't change a mesh size/scale at runtime?

[proper umbra]

At the moment I am trying to add impulse to an actor (Another character). However, when I turning on simulate physics (which allows add impulse to work, the character ragdolls. Any other way to push an Actor.

[spark steppe]

no

[faint pasture]

Have you tried it? It's totally doable

[rocky falcon]

So what's everybody use these days for blueprint unit testing?

[faint pasture]

Is that a thing?

[rocky falcon]

I've heard Rare has had some success with it

Dunno if there are others who also have done it

[faint pasture]

I could maybe see unit testing GAS stuff with it but otherwise I don't really see the point.

Most other BP should be fairly simple

[rocky falcon]

Rare sees a point to it. And I do too. Just wondering what's everyone currently using for it

This looks cool

https://github.com/DaedalicEntertainment/ue4-test-automation

[faint pasture]

I doubt more than 1% of the people here are doing any sort of automated testing. That test suite looks awesome though, might be worth it for like an open world game or something with a lot of required coverage.

[pure relic]

If I was looking to have a camera focus on an object, and the camera will only pull slightly in all directions using the mouse, anyone know I can incorperate that? The focus would never leave the object.

[dawn gazelle]

On tick:

[dawn gazelle]

At least I think that may be what you're looking for.

[pure relic]

I think thats it, thank you so much @dawn gazelle

[stone canopy]

Hello. I'm using a paragon character, now i want it to shoot, but these characters have the weapon mesh integrated in the body skeleton, what could be the best way to work this?

[icy dragon]

Depends. Do you want them to shoot their own weapons, or other weapons you want to provide to them?

[odd ember]

maybe just find the gun socket

on the skeletal mesh

and use that as the location where you spawn projectiles/trace from

[stone canopy]

their own weapon

[icy dragon]

That would be up to the animation, and do either hitscans with fake projectile (most TPS games do this), or actually launch projectile from weapon's socket location.

[stone canopy]

i wouuld be shooting the projectile just when the character fire animation starts

thx @odd ember will research how to do this

thx @icy dragon

[odd ember]

you can use anim notifies to figure out the exact timing you want to fire your gun at

within an animation

[icy dragon]

Though unless it's a special ability shoot, the firing logic should be done the moment player pushes the button.

[stone canopy]

yeah, i know that despite i didnt use much

at first i think the only thing i need is the socket where to spawn the projectile, coz observing the shoot animation seems that the right time to spawn

at the beginning

[icy dragon]

Often times devs prioritise more instant shooting feedback and "bend" the animation to it, at least for regular shots.
You can still use anim notify to wait for special shooting animations.

[odd ember]

that's a design decision

[stone canopy]

ok

[trim matrix]

where can I find this window

its not there for me

[dark crow]

In the BP

[trim matrix]

#hire-a-freelancer

[trim matrix]

yeah

[trim matrix]

how can I make a normal sprint system with a custom made character

[faint cloak]

Just change your character max speed everytime you press a button

Create an action named sprint, call it on your blueprint, then get character movement and set max speed everytime the action is pressed and return it back to normal when release

Guys i want to create an inventory system with stackeable items, i saw the umg ui inventory series on the unreal engine's youtube channel and i already have that structure done

But idk how to configure the slots to make them stackeable

Any help/advice you guys can provide please?

I can show my structure if needed

[faint pasture]

What does your inventory components representation of the items look like?

Just an array of item structs?

[faint cloak]

That's the structure i have

[faint pasture]

Can't go digging into all that. At a fundamental level what is your representation of the contents of an inventory? An array of structs or a dictionary or what?

[faint cloak]

It's an array

[faint pasture]

Array of what?

[faint cloak]

Im going to be honest with you man, it's my first time using unreal and i just followed the tutorial steps

I don't have an idea

😦

[faint pasture]

Show where an item is added to that array

[faint pasture]

K so to do stacking, there's a few ways to do it. At a minimum you need to add a MaxStacks field to your item struct

Then there's a few ways to handle stacking. Simplest would be to also add a Current stacks field to the struct as well

[faint cloak]

Yes, i already have TypeOfItem string variable and MaxStacks Variable

[faint pasture]

K so when you add an item, first check if there's already an entry in the array with the same item and Current stacks < MaxStacks.

So if you're picking up a Potion and you already have an array entry with Potion, 3 stacks, 5 max, then just add 1 to current stacks.

If there is NOT already an entry with current < max, then just add another entry. That'd be starting a 2nd stack.

[faint cloak]

I do understand the logic but since it is my first time with unreal i don't really know how to do it with nodes lol 😦

I am used to work with code lines and i don't know the correct nodes to use here.

I'm pretty sure i can get the "TypeOfLoot" node from the variables I have and just set the MaxStack but in Unreal what's the node i have to use to compare the item im grabing with the entire array to check if it's just going to stack or if it is going to set into an empty slot?

[surreal delta]

Hey guys I'm just looking for clarification of how to describe what type of communication is happening with interfaces. Between event dispatchers and interfaces I mix up describing what is actually happening a lot.

So when I set up this interface. I am inputting a reference to the object variables into "Solved Trigger" part of I_Moveable.

With this action, in this case the "Sender" requires a reference to the "receiving" objects correct?

TLDR. Interfaces only need a reference to the object as the sender. The receiver only needs to wait for the trigger event and therefore does not need a reference - is this correct?

[faint pasture]

Exactly what kind of mechanic are you trying to do here?

[surreal delta]

Well the mechanics work i'm just trying to improve on my lingo when describing how functions work. I mix up the communication types. e.g. what and when object references need passed in.

This trigger basically toggles objects on and off when the button is pressed

so these are instance editable variables. I select the phasing object sets within the play editor

[faint pasture]

That BP snippet is calling Solved Trigger on whatever those objects A and B are

Interfaces just let you define functions that will be implemented arbitrarily in arbitrary classes. Interact is a good example, a door and a button will respond to Interact differently and shouldn't share a common base class. That's where interfaces can step in.

[surreal delta]

Right so interfaces allow for different mechanics to be implemented from the exact same signal

[faint pasture]

Yes

And without a common base class.

[worthy frost]

Interfaces get around the inheritance problem

You might have say InteractableActor, that you use for interacting with in the world

but what if now you want to interact with say another player? or NPC

interfaces make a contract, whatever implements this interface, responds to these functions and handles them.

[surreal delta]

Yes so I guess im just confusing up the 3 communication types for references that need passed in. Just to make sure i'm understanding how each works individually:

For direct communication, only the sender and needs an object reference
for interfaces, only the sending event needs a reference. The "event" in the blueprint does not, as it references itself by default (as an event)
for event dispatchers, receivers subscribe to a reference of the sender

[faint pasture]

@surreal delta those naming conventions are wack tho, I'd expect IMovable to have movement related functions

[surreal delta]

The objects in the game move when interacted with

[worthy frost]

Dispatchers are like, oh this just happened, anything that wants to know about it can be told now

(Dispatchers are just Events/Delegates that get broadcast)

[surreal delta]

dispatchers "subscribe" to the event basically. thats one way ive been told. Its like getting bell notifications on youtube - e.g. only the functions that are assigned to care about it will act.

[worthy frost]

you bind to them, and run something when its called, which can be in the future.

[faint pasture]

On that topic, is there any way to accomplish a global message bus with dispatchers or does it have to be wrapped up in an actor? I suppose a Subsystem could work too for easy getting

[static charm]

Direct comm, only needs sender to have the receiver's object reference.

[worthy frost]

in bp? not sure, in C++ you can make delegates static

[faint pasture]

Hmm Intredasting

[worthy frost]

tho if they are local stuff, you can route them through GameIntance or w/e

[surreal delta]

Ive come to learn my school will likely not teach us anything about the C++ end of UE before i graduate. wondering where I can go to learn that on my own. In a game designer program so more focused on level design

[faint pasture]

So I take it a global SomethingDied buss could be accomplished with a static delegate removing the referencing

[surreal delta]

didnt see anything in the learn hub for C++. Maybe a few things but no beginner stuff. I have a little background in C#

[worthy frost]

yeah tho, i do that via the GameState/GameMode

due it to being only valid during gameplay

[faint pasture]

Just dig in and try to make something small like a BP callable function library to start

[surreal delta]

do you need the VS version of UE to do C++ or do you just tell the project to run C++ files. not sure if prereqs are different

[faint pasture]

I suppose yeah that's no problem because when wouldn't GameMode or GameStaye exist, so no problem with the referencing.

I just like super loose coupling. Just want something to shout into the void that it died and then something else to react if subscribed.

[worthy frost]

yeah we do that via GameState

[static charm]

there's a few options for compiling UE4 c++ these days, but by default you need VS and a bunch of packages but it's all grouped in a simple UE4 dev package install when update/installing VS.

[surreal delta]

yeah thats the first thing i need to look into is that

weve only played with blueprints and thats all were gonna do until i get my degree

any recommendations for schools to get masters? Not sure if it should be in "game design" but after attending an epic games hiring seminar it seems likely I will need a lot of experience beyond school to even get my foot in the door

bit off topic but since were here, sorry lol

[static charm]

yeah you're going to need to ask that in another chat channel, no idea.

[thorny marsh]

@surreal delta Ask in #career-chat

[faint pasture]

Do computer science or just make games. Game design isn't worth much afaik.

As a degree. As a skill it's awesome, bit it's a lot easier for a CS grad to learn games than a game design grad to learn programming. Unless you wanna just do art you have to be able to do a bit of everything yourself. Depends on how big a place you wanna work at tho.

[surreal delta]

Yeah my mindset at first is that I wasn't too worried about programming and more so becoming the prototype artist for levels and mechanic implementation.. The degree is for computer science and we have done a bit of scripting outside of unreal. e.g. practice C# in VS but mostly focused on learning bps

[faint pasture]

This is a great read for general knowledge.

https://gameprogrammingpatterns.com/

[surreal delta]

awesome thank you 😄

but yeah hindsight what your just said is 100% right. I will need to push myself to learn this on my own and if I can find somewhere to learn more programming without drowning in debt that is probably the best

[undone otter]

@faint pasture Not yet, was wanting to learn how to do it., change mesh size at runtime?

[sharp rapids]

@undone otter you mean setting scale?

[faint pasture]

Set scale

[lapis helm]

I've changed the FTableRowBase of a data table, now I can't reparent it and it gives me this when opening it,

I can delete and make a new one just fine, but what if I wanted to change the RowBase of a huge data table? how do I change it properly so it wouldn't break things....

[earnest tangle]

Not sure but the fact you're hotreloading could be causing at least some of it :P

[lapis helm]

so should I close the editor before compoiling the changed data table?

[earnest tangle]

Yes, you should always close the editor before compiling unless you're using live coding

[icy dragon]

https://horugame.com/dont-use-hot-reload-in-ue4/

[fiery glen]

and even live coding can't do everything

it will get better though

[tidal marlin]

Hello. WTF is? How i can get it in blueprints?

I cant find it in....

[earnest tangle]

Hover over the Get Global Settings node and see what it says
