[hollow pond]

I'm just thinking about the project I'm on at the moment lol

[lusty hedge]

oh haha

[hollow pond]

anyway what exactly are you trying to simulate

[lunar sleet]

Your names and avatars are too similar I thought it was one guy having a convo with self for a second there lol

[hollow pond]

who says we're not?

(misty quick type the same thing)

[lunar sleet]

Missed opportunity

[lusty hedge]

):

[lunar sleet]

@dawn gazelle current timeline is as such:

[lusty hedge]

im making a bunch of dots. and making an algorithm to draw a line that shows the fastest route to visit all the dots

as if the dots are location on a map

[hollow pond]

ah, travelling salesman

in that case you can probably just do everything in a widget

[dawn gazelle]

I'm not sure to be honest. I do understand what your desired result is, but I can't think of a better way to handle that kind of situation. I don't think manipulating the playback rate of the timeline will help get those summed values lined up in varied FPS as delta time is always about how long the last frame took with no information about how long the current frame will take.

[hollow pond]

then display that widget to the screen

that won't require any lighting stuff or even any camera

and it being a widget, it's all 2D

but then you have to deal with programming what you want to program in the context of widgets

which might be a bit tedious. you can make entire games in unreal widgets alone but still it's not the easiest way to work

you would honestly have a better time doing this in something like Godot or ditching game engine entirely. Python would work decently enough for this kind of thing

assuming it's just a hobby project and not actually used for something else

[lunar sleet]

Ah I c what you mean. I plan on further optimizing it, I just wanted to make sure machines with lower specs wouldn’t completely break the game (running at 120fps vs 60fps for example)

Hoping ofc the frame rate is relatively stable from one to the next but yeah, I can see how sudden spikes would break it

[slate hound]

did you see my solution to spawn the dots in #ue5-general ?

o.o caught cross-posting

[lusty hedge]

i gave in and went with a 3d thing

[lusty hedge]

does anyone know why debug lines clip ?

[modest tinsel]

Where would I put the clamp? could you show me how the code woulld work if you dont mind! sorry ask! 🙂

[lunar sleet]

I might have misunderstood your question there. Is this to give your players a camera sensitivity option or what’s the end goal ?

[modest tinsel]

So like right now I can move my character camera like my screen really fast but I want there to kinda be a limit to how fast it can move like your camera can only move so fast you know? 🙂

[woven pond]

Is it possible to get the player controller from who is clicking on the event ActorOnClicked within an actor?

as in get the controller that is clicking on an actor from within actor

[lunar sleet]

show the code where you set the camera movement

[lunar sleet]

I mean get controller should return you the correct controller anyways

[modest tinsel]

I dont have any code to set the camera movement yet I was asking if you knew any code where I could make my camera not be able to go really fast you know? kinda how you can adjust your mouse sensetivty

[woven pond]

might be because of how iu am imagining this but if i have a custom actor and am using event on actor clicked i was thinking of getting the player controller that clicked on the Actor but i may be approaching it wrong

[lunar sleet]

I mean #multiplayer is a diff beast but generally speaking if you do onClicked, get controller and plug that into the cast or w/e is on the execution path , then you should get the correct controller instance. If this is not multiplayer and you’re still think this way, then you’re def looking at this wrong lol

[lunar sleet]

Well how do you know it’ll be fast if by you haven’t set anything up yet? 😀

[woven pond]

was trying to look at it from a MP way

[lunar sleet]

Yeah, get controller does the job for you usually, but if you experience it differently ask in that channel

[modest tinsel]

Not sure someone told me I just needed a clamp or smt 🙂 sorry to ask

[lunar sleet]

You asked how to cap a max speed value hence why I said clamp

[woven pond]

will do

[lunar sleet]

But really you don’t need that, you probably just want a way to control the camera from what I can tell, at which point you’d have to expand on what type of game this is (RTS, FPS etc)

[elder lodge]

I've been using a Capsule Collision and Line Traces to make some magnetic shoes work for wall walking, but I'm thinking that a Sphere Collider underneath the feet would be better.
But it looks like only Hit events will generate the normals I need; is there a way to set the sphere collider to generate hits but also not block anything?

Right now in EventTick there's a line trace happening when they're on the surface

Feel like it'd be better in a collision/overlap event but overlaps cannot generate normals

[lunar sleet]

no, but what is the actual issue you're experiencing?

[elder lodge]

Honestly no issue fundamentally yet; I'm wondering if for "future" performance it may be better to have the logic triggered whenever the shoes are in range of a surface;
Right now I have a collision event with the bottom of the character which triggers a bool for the shoes to work; then while the shoes are working and on a surface, they continuously check the floor to make sure the player is still on it and hasn't walked off an edge.
That continuous line trace feels like it may be an inefficient way to do it. Begin/End Overlap could be useful triggers but there's no normal information, so I'd ultimately have to fire a line trace inside that trigger instead.

[trim matrix]

hey all so i have this widget feature showing (Collect) and im trying to change my previous feature where if you walked into the collision box it would destroy, i would like to now have my character press E in order to destroy the object instead, i have setup the IA_Collect as well as added the input to the IMC, so im just wondering if i can add the input into the object itself or i need to do it via the Thirdpersoncharacter

[hollow pond]

if you did it in the object, then multiple objects would be able to respond to that input at the same time. pressing E would collect all objects in the level at once.

it makes more sense to do it in the player character, using a line trace to only interact with what the player is looking at

[trim matrix]

it has a sphere collision, so when a player walks into the vicinity to that one singular object, it will show

[trim matrix]

but wouldnt that mean that if i walk into one object all would dissapear? that doesnt sound right cos they dont all dissapear unless its the correct answer that has been destroyed

[hollow pond]

you could use that collision to allow/disallow the IA_Collection from running its code, but you'd still be able to pick up multiple objects at the same time, assuming that you're overlapping with multiple

[hollow pond]

no, because each object has a separate collision sphere with its own overlap event

your IA_Collection input is something that all objects will be able to listen to at the same time

[trim matrix]

o

[hollow pond]

I don't think there's anything seriously wrong with handling it in the objects (assuming you still use that collision sphere to ensure that the player is within range), but I would not do it that way. I'd use a line trace from the player's camera

[short ivy]

why is this not rotating the camera correctly to the new checkpoint?

i am getting the correct checkpoint location

and it is rotating the camera

just the rotation it ends up with is wrong

not like inversed or such, just random kinda?

[lunar sleet]

it's the rInterp

it doesn't do what lerp does, it's more like some curve thing

if you want just a smooth transition between 1st rot and 2nd rot, just use a lerp and a timeline or such

[short ivy]

now i have it like this but its still off the target

sometimes it's kinda close but sometimes totally off

[lusty hedge]

any reason this might not work?

[lunar sleet]

where is the code?

[lusty hedge]

in an actor BP

[lunar sleet]

you need to enable input

[lusty hedge]

:/

[lunar sleet]

it's not enabled by default in regular actor dudes

[lusty hedge]

O

how would i go about that?

[lusty hedge]

on begin play?

[lunar sleet]

yep

[lusty hedge]

ty

[lunar sleet]

np

[thin panther]

its worth noting that proper input routing is preferred to that

[lunar sleet]

you're rotating the spring arm, try the camera maybe

[lunar sleet]

wdym

[thin panther]

(don't worry, the enable input node summons my presence :P)

[lunar sleet]

you signed up for Enable Input Google alerts? 😄

[thin panther]

routing enhanced input actions from the player controller via event dispatcher or whatnot

[lusty hedge]

still doesnt work

[lunar sleet]

oh yeah, def should use EIS normally, but I figured this is just prototyping @thin panther

[lunar sleet]

see the player controller pin?

[lusty hedge]

yes

[lunar sleet]

you need to feed it something

[short ivy]

nah thats not it

[lusty hedge]

but i dont have a player controller :.

[lunar sleet]

use the get player controller node

[lusty hedge]

im just doing a simulation

[lunar sleet]

there's always a player controller

else you wouldn't be able to control the actor

[lusty hedge]

works ty

[mental trellis]

There's no pc in simulation, is there?

It just runs the physics.

[thin panther]

you'd be surprised the number of people i see trying to use things like that for game code in stuff they want to ship. even more so with raw keyboard events. It hurts my soul because i love to remap keys :P

[lunar sleet]

yeah, I feel you. I just figure if they have to ask, they're not even in the same hemisphere as the shipping stage, so they have lots of time to correct their ways

[thin panther]

absolutely. i always find it handy to mention as the proper method so people know of it when they want to tackle it :P

there was a lot of bad stuff i stuck with for so long purely because i didn't know of the better thing's existence

[lunar sleet]

You are 100% correct, doesn't seem like it.😅

but I mean normal code still runs

which is weird because I have an AI MoveTo that works just fine in Simulate mode. Yet nothing will print on begin play or Onpossess for controllers for some reason

[lunar sleet]

yeah fair point

[thin panther]

I believe the ai controllers still work and everything, it's just because I believe the game mode is nto spawned in simulate

which handles the player character, HUD, controller etc

[lunar sleet]

but I mean

if I put a print string on the AICon's onPossess or Begin Play it doesn't fire

yet it'll do the move np 😄

[thin panther]

to github!

[lunar sleet]

fer what? 😄

[thin panther]

to look at the aimoveto node

[lusty hedge]

I DID IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i made a program to draw the shortest path to visit all the cubes!

took me 3 hours

[lunar sleet]

that's decent

[lusty hedge]

yeah

its not reeeallly the shortest path

but its the shortest path it can find

with x amount of scans

the algorithm SUCKS

it justs hits random cubes and measures the distance at the end

and saves the best result

so random isnt good when we hit say, 30 cubes

but im happy for now

[thin panther]

now the plot thickens, it definitely needs an ai controller

[lunar sleet]

look what you started @mental trellis

[short ivy]

@lunar sleet i just noticed sometimes when it's off then its exactly on the opposite direction

[lunar sleet]

you're prly over-rotating

like it's rolling over 360 to 0 or w/e

may need a clamp axis or normalize, can't rmbr which

do some debugging with print strings and manual rotation settings and compare results

[lunar sleet]

yeah, I can't figure out how to tie world delta to the play rate properly, so I'm gonna try what you suggested and just have it lerp between fixed values. Even if I have to use 3 timelines, provided it works, I'm good with it 😅

[thin panther]

I am now going to stop looking at ai controller code because my head is hurting how your ai move to is successful but OnPossess is not called

[lunar sleet]

lol yeah that's a rabbit hole for sure

[versed sun]

Wrap

[lunar sleet]

yeah guess that could work too

[elder lodge]

I mean
You didn't give yourself an "easy" problem. The traveling salesman problem is classically difficult

whole industries dedicated to it!

[lunar sleet]

We have Zoom now 😛

[lusty hedge]

it feels really good as a beginner to get it done. I think it maxes out around 12 destinations

thanks 🙂

i think instead of entirely random ill do the next version where maybe the "saleman" goes to the closest point. and has a 50% chance to go to a random one. i think that will speed it up

[lofty rapids]

from what i understand it's one of the hardest problems out there, not too many good algorithms that make a good path

[lusty hedge]

would it be unrealistic to save previous attempts ? so when its running paths randomly it doesnt repeat?

is there an easy way to save 200,000 attempts?

or even a million

[versed sun]

make a save game for each attempt

[lusty hedge]

im a noob so idk if youre trolling

[versed sun]

1/2 and 1/2 , more of, you could use a Save Game to save the results in an array
I'm not sure how many items an array can hold

i think it depends on how much data you are saving

[zealous moth]

max float probably or max int i guess

[trim matrix]

back to the earlier convo @dawn gazelle , That timeline works great, but I have to tackle the second part of the issue, start N amount of timelines where N is the length of the array, all running concurrently

For each loops are weird, they don't seem to work

[elder lodge]

Why reinvent the wheel? Go to the wikipedia and look at the heuristics algorithms that exist.
I think I saw something fairly recently that mentioned ways to do it using heuristics about the distance between nodes.
Offhand, I would never do entirely random. I'd do random changes from the best solution so far. You might wind up stuck in a local minima, but maybe there's a way to shake it up a few times.

[elder lodge]

Traveling Salesman is n-factorial I think

As an exercise I suppose it's fun to optimize on, though

[lusty hedge]

i was honestly just challenging myself without any research to see what i can come up with

how do i share code. my new version keeps crashing

not sure why

(blueprint)

[versed sun]

I have an answer for you, and its fun one...
Make your own "Timeline" Function, and run on tick
Make an Int Array that holds the indexes of your N timelines (Mine is Moving Pieces)
Make a Float Array "Alphas", each alpha(0 to 1) is going to be the % done you are with the timeline
Then make an Array for each value you need to use in the timeline (Mine are Mats, and Halfway Point)
Inside the function , For each Loop thru the Indexes , and use that to Get each on of your other Arrays
Increase the Alpha for each by either Delta (or some other math), and Set Array Elem back in the Alpha Array
Then do whatever you would do with the rest of your "Timeline's Update"
Once the Alpha for each Index reaches 1 , Remove that index from all the Arrays
Also, this runs each index independently of each other , you can start one "Timeline" then start another .5 sec later , and they would finish .5 sec apart

[elder lodge]

Yeah I get it
I did that with prime factorization back in the day

it's fun just to see how much better performance you can keep getting

[dawn gazelle]

Could you not just run one timeline and update all the values from the array? ie. update from timeline does a foreach over the array?

Or do they each need different speeds?

[lusty hedge]

ill probably do that when ive maxed out my current improvisations

Can i stop Unreal from saying "infinite loop detected"

im pretty sure its wrong

BECAUSE it works when i loop it less

if i ask to loop it 20000 times it thinks its infinite and stops it

[versed sun]

you can change the Infinite Loop number in Project setting , i think

[lusty hedge]

my new method seems more efficient but runs slower..

hmm

the first one goes completely at random. can run 100 thousand times with little delay.

the 2nd one has a 75% chance to go to the closest cube next and a 25% chance to go to a random cube

logically i thought that would do better.

its hard to say for sure without seeing hard data but i think its more effective but slower for each loop

https://blueprintue.com/blueprint/81fgrxd-/

can someone review why it thinks i have an infinite loop here?

or just review the code in general if they feel like

im a beginner

my new version seems to work in 2000-5000 scans

last version was up to 400,000 scans 🙂

not tooo bad

alright sorry for flooding the chat

thanks guys

[trim matrix]

Each need diff yeah

[trim matrix]

Oh so you do all the logic in that function, and use it in a seperate place by calling the functions?

[trim matrix]

Wait a minute, this function replaces the timeline?

[tribal gazelle]

Say I have a list of commands in an array (/cmd1, /cmd2) how would I go about showing them as a string, in order? Like: Commands: /cmd1, /cmd2

[trim matrix]

Here's the crux of the issue, pass in the index of the array, but make a new copy of the loop body's contents

[wicked magnet]

Does anyone know how to get multiple points on surfaces within a certain radius?

[modest tinsel]

Thirdperson naruto based pvp game

[dawn gazelle]

You can loop through the array and append the items in the array into a single string, splitting them up as you need.

[trim matrix]

OOC, how'd you get the straight lines?

Ohh is it this @dawn gazelle ?
https://www.unrealengine.com/marketplace/en-US/product/electronic-nodes/questions?sessionInvalidated=true

[trim matrix]

this is how you get the closest point on surface. https://docs.unrealengine.com/5.3/en-US/BlueprintAPI/Collision/GetClosestPointonCollision/ To get them points within a radius, you could do a multisphere trace and then iterate through each hit component and run the find closest collision point node where the Point would be the Impact Point of each hit result

[lilac storm]

hey there i am facing a crashes , all the time different crashes , nullptr crashes , invalid index crashes but log does't say where this crashes are happening ? is there a tool or something to try to catch this staff?

[trim matrix]

Is ur project bp only?

[lilac storm]

yes

[trim matrix]

might be some plugin

[modern radish]

what is a blueprint interface, how does it work, and should I favor that over event dispatchers (what I've been currently using a lot in my project)?

[faint pasture]

They are completely different things

Interface is a set of common functions (name and signature only) that can be implemented differently on different classes

dispatcher is a pub-sub model thing. Dispatcher is triggered -> bound functions are called

[modern radish]

Ah okay, got it. and how does an interface differ from a function in the blueprint function library, for example?

[lilac storm]

can i change texture quality for a build , for example 1 build for high gpu ,1 build for low gpu ?

[dawn gazelle]

When you define a function in a function library, any place you call that function will execute the function as you've defined it in the function library.
When you create an interface, you only define the potential function. When you call the interface, the target object needs to actually implement that interface and each object can have its own set of instructions when that interface is called.

Eg. I can have an "Interact" function defined in my interface. In my door blueprint, I implement the interface and define the "interaction" function so that it swings my doors open. In my treasure chest blueprint, I implement the interface and define the "Interaction" function so that it opens an inventory. In order for my instructions to be passed to these objects, I must first have a reference to these objects, and then call the interface on them. So if I have a reference to a door, it'll call the door's implementation of the interface. If I have a reference to a treasure chest, it'll call the treasure chests' implementation of the interface.

[thin panther]

You don't need separate builds for that

Just use graphics settings

[modern radish]

Okay yeah, thanks a lot for taking the time. This was helpful

[true oriole]

hi, i am trying to create a projectile that have a sine/cosine movement. these nodes works but how do i control the speed of Y movement ? currently it's too slow.

[thin panther]

Don't crosspost

Read the #rules

[pliant sorrel]

what does speed do?

[true oriole]

i was referring to the speed of thunderball move from left to right and right to left

[trim matrix]

You mean you want to speed up the sinus movement?

Multiply the time you pass into the sinus

by some const

[true oriole]

yaya. that works. thanks. 🙏

[young meteor]

I'm doing a tower defense, and want to keep track of how many damage each tower has done, and combine that to a save file for unlocks and achievements as well.

After I implemented a save game function every time a tower hits an enemy I get small Hickups (lags), every time.

Do you guys thing I should look into optimizing the save game function (right now I save all variables when I do it), or is it simply not very realistic to save the game every time a tower shoots?

[versed sun]

are you saving game to slot each time ?

[trim matrix]

Do async save at the very least

[young meteor]

yes

[trim matrix]

Not the normal save to slot

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/SaveGame/AsyncSaveGametoSlot/

[trim matrix]

Is that code in a function?

[young meteor]

yes

[trim matrix]

Make it into an event

[young meteor]

In the event graph instead?

[trim matrix]

Right click on function in the list

[remote meteor]

why do you need to save game after every hits though

[trim matrix]

and select to event or something like that

[young meteor]

Not sure it is strictly needed. Almost certainly is not. Was just the first easy attempt.

[trim matrix]

like this https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTzqG9ds_l96JVpXk2abHZt8NXDPokZkGIcwzDXMrTzVPd-sc4mI6_yMMBEO62twsnOvm0&usqp=CAU but the other way around

(You click on the function instead of the event)

sorry for shit image quality

pulled this gem from google imgs

[young meteor]

Oh okay. Can't really see what it is.

[remote meteor]

not a good idea to save that often

thats for sure

[trim matrix]

It says "Convert event to function"

[young meteor]

Convert function to event

[trim matrix]

But when you'd right click on a func, it'd say that yeah

[remote meteor]

you can hold on to the save game object for awhile, save during a mapchange, wave, actually unlocked a achievement or what not

[young meteor]

Right. I think I should go about it like that. Just curious to learn what ssolve is trying to teach me now too.

[remote meteor]

async save is fine

calling it multiple times in a row is questionable though

[young meteor]

Only concern is people getting some loot or something they love, and then crashing.

Would make more sense to save in that instance though.

[clear sierra]

that is some ugly truth that happens, but you need to focus on fixing your crashes, instead of saving per second,
Does not make sense.

[young meteor]

Got it. Thank you. 🙏

[trim matrix]

you could add a simple retriggerable delay also to where it is about to save Nevermind, that would not make them save as instantly as before tho

[young meteor]

Right

The whole point of converting the saving function to an event was? 🙂

to allow for async?

🙏

[wise raven]

My project crashes when i tick weld simulated bodies, is this normal?

the vehicle mesh is a static mesh, the parent in heirarchy, and the mesh is a skeletal mesh under the parent static mesh, both are set to simulate physics

[thin cradle]

hey, right now the default character, when moving, instantly moves towards the direction added in AddMovementInput, and slowly rotates to face that direction
Is there any way without custom code to instead make it always move on its forward axis while still slowly rotating towards the intended direction?

I'm trying to figure out how to make a "Quit" button open up a Yes/No prompt for the player they must answer "Yes" to before closing the game, but I think I've been staring at this too long and the answer isn't coming to me. I've created a widget with the prompt in it, but I am spacing on how to actually return a true response to the "Quit Game" command branch when the player clicks "Yes". Any tips?

[thin panther]

im not exactly sure what you mean there

it's just Click Yes > Quit, Click no > destroy widget

[clear sierra]

have close button somewhere, But people can always do alt+f4 to quit, if you want to override that ?

[fringe coral]

yeah, you're right. I'm clearly too tired and need sleep. I was totally overcomplicating things.

[thin panther]

get some sleep, sleep is good :D

[versed sun]

Event Dispatchers in a Widget are your friend

[wise raven]

because both are simulating physics bodies, and i need at least the skeletal mesh to be attached ( welded ) to the parent simulatiung body without it flying away

[clear sierra]

are they already attached in component space ?

[wise raven]

looks like this

[clear sierra]

so you are saying when Mesh is simulating physics, it flies away ?

Maybe you should like into Physics Constraints

[trim matrix]

is there a way to set variables according to the skeletal mesh?

if the skeletal mesh is named Pistol Set variable to something

you can get the Meshes name , and Select on String

[zinc flicker]

Why cant i look around when using "set target with blend" even when i setup "Axis turn and axis lookup"

[crystal crown]

You mean the character can move but camera is stuck in one place?

[lunar sleet]

The new camera may not be tied to the controller/input

[zinc flicker]

Exactly its like only this 1 single angle i set with the camera inside.

https://youtu.be/gHJ4pHlqAzQ

I tryed to follow that step by step but it dosent accept my lock input

in the tutorial it works i am just not sure if that no longer works in 4.27 he maybe uses an older version ?

[trim matrix]

have you enabled input on your locker actor/pawn?

[zinc flicker]

No way... it worked, thanks i didnt use enable input since i use the Interaction Plugin... i was thinking the enable input is only to enable pressing "E" to enter.

Thanks a lot so i guess Enable input counts for every input even moving around a mouse

[zinc flicker]

I am required to Disable Input again on leaving or does that not matter?

[frosty heron]

Having input to actors you don't own, usually considered terrible

If you detect key press in your locker then I do suggest to scratch that and redo the input bit

Your locker or any intractable object don't need to know input. They simply have interacted function or event that get called

Eg , player line trace. Check if hit actor have interacting comp or implement interact interface. If they do run, interact event

[zinc flicker]

Ah i see so the Enable / Disable input is only bound to that specific actor so when i leave a locker he dosent need Input Enabled anymore.

[trim matrix]

It's sometimes needed though

[frosty heron]

Locker shouldn't even need to read input

That's terrible

Why do u have to run input logic on actors you don't own? That's gonna be hell to debug

U r just shooting your self in the foot

Don't have to take my opinion, try programming lounge or smart ppl

If your tutorial suggest doing that. Honestly just delete it from your Web history, actually very harmful

[trim matrix]

calm down please, it's just an input axis

for reading the mouse input 🙂

What would be better than?

A pawn?

or handling the locker state in the player?

[frosty heron]

I'm only reading this bit

If locker need to read input instead of the player then that sound really wrong

I wrote the most common approach with interaction.

There are better ways and there are worse way. Also there are way you shouldn't do. Having a locker reading your input is one of the things you shouldn't do

[zinc flicker]

I use the Input action only for the "Set Target Blend" so that i can look around inside the locker, without input it would be just stationary camera that looks in 1 direction.

[trim matrix]

It's the most straight forward approach I'd say

You could do that entirely in the player tho

[frosty heron]

Well in this case i dunnoe, if something is possessed in a sense then maybe it's okay

I thought it was for some sort of interaction system

[trim matrix]

@zinc flicker you already have a bool in your player for when the player is hidden, right?

[zinc flicker]

Ah no i just wanted to create an option to hide in a locker the "interaction system" is the thing that create the button he named it like that :D

[zinc flicker]

No i have it only set in the locker basically when you enter the locker your character existence is no longer there.

[trim matrix]

ah never mind, ima misremembering that tutorial i guess 🙃

[zinc flicker]

At least i figured it out but its good to know that "Enable Input" is not something that random stuff should have.

[trim matrix]

Yepp

[frosty heron]

Well if you need to drive the thing then

Just make sure to disable input when you get out from the car/locker imo

[trim matrix]

So you respawn the char?

damn thats crazy

[trim matrix]

Spawning stuff with BPs isn't exactly the most efficient

[zinc flicker]

i made him Hidden

[trim matrix]

Ah no you just hide them

[zinc flicker]

At least my AI no longer detects me when i do it that way.

[trim matrix]

Keep in mind that they still can block your ai

[zinc flicker]

Ah you mean the Capsule?

[trim matrix]

Yepp

[zinc flicker]

So probably best to make the Collision go away too.

Basically like this right?

[trim matrix]

I guess

[zinc flicker]

Thanks again for the help =)

[distant garden]

My camera has no pitch value, even though i can pitch my camera

How do i fix it

[feral ice]

i want to have directional roll depening on camera angle and where player is facing. And im doing this by using calculate direction and it works how i want it to work when the player is still but once i am moving and roll again it will always go in the direction the player is moving because thats where the velocity vector is pointing. How do i make this work even though the player is moving?

[crystal crown]

Did you even search for tutorials?

[feral ice]

yeah if i did. Cant find a one where it depends on your camera

[zealous moth]

is there a way to get the distance along spline closest to a vector?

[crystal crown]

you want it to roll where the camera is facing?

[feral ice]

yes and i want my key inputs to also have an inpact

[distant garden]

make another vector

[feral ice]

here i am looking sideways but holding d which makes the player go backwards and also roll in that direction. The same as using blendspace @crystal crown

[crystal crown]

well my dodge is the same as in the tutorials cuz i'm using controller rotation. it's the same in dark souls. It doesn't make sense to turn your camera away from the enemy just to dodge

[feral ice]

have you played the wicther, they have that feature there

[lunar sleet]

https://tenor.com/view/goodbye-wiktor-goodbye-wiktor-gif-21120394

here is what i mean

[crystal crown]

Not sure how to do that. Maybe someone smart can help

[chrome pumice]

yo dudes i cant foliage brush anymore for some reason, i seleceted paint but my mouse curser is keep displaying as a "+"

any idea how to fix? i had this for days now

[lunar sleet]

Try #level-design maybe

ahh aight

[sharp crane]

Hi, got a general UI question. Is it better to have 1 HUD widget with a lot of functionality, or multiple small widgets that spawn/remove from parent as needed?

[carmine palm]

Trying to make it so if you are in range of a chest (overlap of volume) and also looking it it, it outlines the object:

Currently have this (thought I saw this online for checking if an object is looking at another object)

But I'm not sure what it wants for object type array

[fallow elm]

Hey guys, does anyone know why this could happen? My subtract node is straight up not subtracting (resulting in 0)

[carmine palm]

oh wait I got it

you have to makearray lol

[trim matrix]

store a vector from both input axis and add into onto the camera's forward vector 💁‍♂️

[feral ice]

yeah i see what you mean but how do i do that?

[trim matrix]

Is there a get input axis value node in BPs?

If there is, you could use it to construct the vec

[lofty rapids]

the chances of the subtract node failing are slim

[fallow elm]

I know right, what's weird is that it works when its output is hooked up to a node in the execution

[random pulsar]

guys i want to connect here like i drew but when i do this the 1st select disconnects

[random pulsar]

how can i connect both of em?

[fallow elm]

When it's hooked up to a print string it's subtracting, when it's not it doesn't

[lofty rapids]

well tbh either way it's subtracting

[lofty rapids]

the print string shows the correct value then it's working, something must must be wrong with how your using it

[fallow elm]

But when its not hooked up to print string, the Lerp (Rotator) node is receiving a zero, which makes it not work

I dont know how I'm "using" the subtraction node wrong I guess is what im trying to ask

[lofty rapids]

your sure it's recieving zero ? also where is the execution that goes to that ?

[fallow elm]

I unhooked it from print string:

[thin panther]

print the rotation instead

bp watch values are notoriously bugged

[fallow elm]

okay will try that

[dawn gazelle]

Just as you wouldn't build your entire game within your player character, you don't want to to build everything into one widget.
You want to make widgets that can be reused.

[dawn gazelle]

You can't connect both of them up as it wouldn't make sense. You can't set it to use a sprite based on one condition and then tell it to use another sprite with a different condition in the same node. If you want to combine conditions you can. For example, you can take your return value from the top select node and feed that into the False pin of the bottom node. The true value on the bottom node should be your "death" sprite. You'd then connect the return value from the bottom node to your Set Flipbook node.

After doing that, it would first check if the health < 0, if so, show the death sprite. If the health is >= 0 then it'll set the sprite to the movement ones based on how fast its moving.

[steady night]

Hey Guys

i need Advice on how to Formulate .

[random pulsar]

like so?

[thin panther]

formulate what exactly?

[lunar sleet]

A formula, obvi 🙃

[steady night]

Classic

no, this shit

this wont work

the problem im having is that i have "melee damage + -" and also melee damage +% - %

not a better way of compiling everything

need*

the main problem is basicly the final step when adding the damage with % plus or % subtract

[thin panther]

im not sure why you have separate values for those

to add 0.2 damage, + 0.2
to take 0.2 damage + -0.2

[random pulsar]

also the animation does not play i think its because it destroys the object once projectile collided with rabbit so i need to make a delay on nodes i think,but i tried and they didnt work well

[steady night]

wdym

[thin panther]

you have to variables for positive and negative damage

which you don't need

[steady night]

but i do :/ ? i mena this is a line of "buffs stats stuffs" some give - to flat damage some + to flat damage Some minus to % damage and somme plus to % damage so

thats why i need

[mental trellis]

Don't do math in bps.

[thin panther]

no you don't
a buff that gives positive damage is adding its damage
a debuff that gives negative damage is adding -damage

[thin panther]

also this

[lunar sleet]

You can + a negative value btw

[thin panther]

math in bp is awful

[lunar sleet]

Por que?

[mental trellis]

At least use the formula node or whatever it is node.

[thin panther]

spaghetti hell and lots of node jumping

[lunar sleet]

Ah

[thin panther]

prefer c++ or math expression

[lunar sleet]

Expression ?

[mental trellis]

Maybe?!

[lunar sleet]

😀

[mental trellis]

Yeah.

[lunar sleet]

I keep forgetting you strictly live in 5.4+ cpp now 😀

[mental trellis]

That's just my lack of bp knowledge showing, not 5.4 😛

[noble ledge]

Does anyone else run into an issue with the debugger just freezing for like 4 minutes because you accidently hovered over a pin?

[trim matrix]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/MathNode/ do you mean whatever this is?

[lunar sleet]

#blueprint message

[mental trellis]

Probably.

[trim matrix]

it sucks.

[mental trellis]

I mean you're using BP, that's the standard.

[lunar sleet]

I need to lerp something between x and x + y without it being frame dependent, any thoughts ?

[thin panther]

its far better than math spaghetti

at least it generates the spaghetti for you

and hides it

[trim matrix]

exactly

it still does the 🍝

[thin panther]

well you aren't exactly going to escape that in bp so it's a moot point

sure the spaghetti ain't great but tackling c++ for a single math expression is slightly overkill

[hollow pond]

oh neat

[trim matrix]

no, it's not neat

it sucks.

[mental trellis]

DeltaTime

Or record the start time and, when you resolve the value, work it out dynamically.

[hollow pond]

I can debug a math expression much more easily than debugging a nest of nodes and wires. even if that nest is neatly organised and laid out, it's still a nest.

and as ACT said I'm not gonna jump into C++ for one bit of math

[lunar sleet]

Yeah, I figured it included delta time but how to integrate it

[thin panther]

(granted it's ideal if it's a mega big bit of math, like path finding, or wave function collapse)

[lunar sleet]

Doesn’t exactly work with a timeline play rate ^

[thin panther]

but for applying some damage, just use math expression

much cleaner

[hollow pond]

oh yeah. I learned that the hard way.

somewhere on my computer there is a screenshot of my very broken A* pathfinding in entirely blueprints. it's easily the worst thing I've ever done

[thin panther]

but yeah, you find out pretty quick through profiling if your math is too much for bp

and it nearly never is, Fluid Ninja Pro is a bp plugin after all

[mental trellis]

More information required. What's wrong with a time line that updates every tick?

[lunar sleet]

Sec I’ll pull the message link

[thin panther]

i still opt for c++ because i don't like spaghetti hell, and the math expression in my experience can break with super large expressions
(i also just prefer c++)

[dawn gazelle]

Rather than destroy actor, try using Set Lifetime. This can make it so the actor disappears after the defined time.

[crisp urchin]

Gosh i have to convert that plugin to cpp for my projects,

[lunar sleet]

#blueprint message I need this to happen without having to feed it precise vectors to lerp between every time and regardless of current fps

[mental trellis]

Use your timeline as an alpha with values between 0 and 1.

[lunar sleet]

I did yeah

Datura suggested that

[mental trellis]

Define what 0 and 1 mean somewhere else.

[lunar sleet]

It still seems to be affected by frame rate tho

[mental trellis]

Then when your timeline ticks, set whatever your value is to 0value + (1value - 0value) * alpha

[lunar sleet]

Oh ?

[thin panther]

my condolences

[lunar sleet]

Where does the delta time come in then?

[mental trellis]

It doesn't.

It's handled by the timeline.

[lunar sleet]

Oh ok

[mental trellis]

If you say "go from 0 to 1 over 5s" then it will handle the calculations.

[lunar sleet]

I see

I’ll try that thx !

[mental trellis]

If you want to get fancy, you can also feed the timeline output into a curve which remaps it to a new 0-1.

[keen widget]

how to switch this to another int? like Do stuff if int is - "596" ?
when i press Add pin its always get incemented by +1

[trim matrix]

idk what your goal is, but you're probably doing it wrong :/

[keen widget]

i want to do stuff only if integer is = to 1 or 2 or 20 or -999
in other case do Default logic

[mental trellis]

You could create a map of int -> int.

[copper hawk]

what would be the best spot to put this code? I want it to show after you click the button to be put into the dungeon. It is a "blobber" game and I want it to show only once you enter the dungeon

[mental trellis]

Map your required values onto the input of the switch node (0, 1, 2, 3, etc)

[copper hawk]

FYI: i am using an asset from the asset store, I am modifiying it and expanding upon it though.

[keen widget]

i like your idea 🙂

[copper hawk]

Currently what it looks like. (everything is a placeholder, including the AI Art) I want it to only show once you click the highlighted button.

I would assume when you click the button it fires an event?

[lofty rapids]

i don't see a button ?

[copper hawk]

even though this already exists there, so I would need to add it after?

[copper hawk]

I circled it. Second attachment.

[lofty rapids]

the dialogue is part of the widget ? or that's going to run before/after ?

[copper hawk]

After you click the button that says "ENTER DUNGEON" I want it to kind of be like a story that shows once you enter the dungeon

[lofty rapids]

so that is running where ? when you add to viewport ?

[copper hawk]

the code that makes it appear currently? it runs when the game is started. Just put it there to test

[lofty rapids]

there is an event for clicked of a button

you could do it at some point when the level loads

[copper hawk]

Yep, it is here. Already being used. I did try to put it after, but that didn't work. Will try again and update

[lofty rapids]

you can do it when something loads like your controller or level or even character beginplay, this would carry on to other levels

but i like to store the widget in the HUD

for easy acces

[copper hawk]

Would I need to add a delay?

I see, it doesnt even get there. Bizarre.

it doesnt print creating

so that means it isnt even getting there

nvm, it is. printed again and it works this time

updated code, it prints all it needs to print. it just isnt appearing

[lofty rapids]

open level most likely stops the code and loads everything fresh

[copper hawk]

Hmm

Maybe youre right

[trim matrix]

almost definitely even

[copper hawk]

sorry, I am new to Unreal

[lofty rapids]

you got to put it somewhere that loads when the level loads

[copper hawk]

Understood

sorry

[trim matrix]

no need to be sorry smh

[lunar sleet]

😭

[copper hawk]

ok, thanks guys. It just does it four times now. lol. I know the reason, just don't know a solution.

hmm

[lunar sleet]

Wanna tell us the reason?

[copper hawk]

i put it in here. (First image) and it does it four times because it loads that 4 times. (third image)

[copper hawk]

i was typing it, lol

[lunar sleet]

Get player char, cast to your char bp

[trim matrix]

bad place to store that i think anyways

[copper hawk]

Yes, I agree. I am thinking its best to place it somewhere that runs when you click play and doesn't do it in a widget.

[trim matrix]

i was was referring to the other guy 😅

[copper hawk]

oh ok

sorry

[trim matrix]

@copper hawk where have you placed the code now?

[copper hawk]

Here. I will show

[trim matrix]

👍

[copper hawk]

didnt move it yet. was trying to find a more suitable place

[trim matrix]

could you explain what is what and where is there?

[copper hawk]

Sure

[lofty rapids]

you may be able to use the hud, will there be multiple levels ?

[copper hawk]

yes

[lofty rapids]

i would store some sort of status in the game instance

[copper hawk]

ok, so you start the game. it puts you in a dungeon. This Widget is the widget that shows on the bottom left corner of the screen. that clones 4 times, or based on how many heroes you have, which is 4.

[trim matrix]

what is wbp bottom dialog box?

[copper hawk]

The dialog box that appears at the bottom. This is all the code in it, and this is the image of what the Widget looks like

Yes, I am using a plugin to do a typewriter effect. easier then writing my own code lol

[trim matrix]

ok, when does it need to be created?

[copper hawk]

After you click this circled button.

which cant be used. Because that is what loads the first level

[trim matrix]

You could do this either in a Game Mode BP or the player controller/character

on begin play

[copper hawk]

Ok, will try

worked, thanks! Now does it show everytime I die or what

[trim matrix]

if you've placed the logic inside the player character, and you destroy it and then respawn it, yep

[lofty rapids]

pretty much game instance you can use to keep data across levels

so you could have a variable that holds the current status

[trim matrix]

no we're talking about displaying a widget

upon entering a level

[lofty rapids]

i'm talking about because it reloads like that

you could hold a status in the game instance

so when it loads checks the status thats where your at with it

kind of base the display off of that, and theres multiple levels so it would load when you load another level also

[trim matrix]

i would do it in the level bp if it's for just 1 level

[lofty rapids]

you could create it in the HUD, store the status in the instance, you would be able to keep track of where your at

thats if the thing works when you add to viewport which i would guess

[trim matrix]

@lofty rapids i still think we're talking about 2 different things...

[lofty rapids]

if your just going to use it as an intro in that one level ig the level bp.
but what if you wanted to re-use it and say stuff at other times

[copper hawk]

What do you mean "Level Blueprint?"

[copper hawk]

Yeah i found it haha, but thanks anyways

Yep, it works perfectly. Thanks guys! Really appreciate it. 😄

[trim matrix]

You generally don't want to use level bps as their code isn't reusable

but it works in this case soo

[copper hawk]

thanks guys, i really appreciate it

Ok, new issue. When i click, it makes a copy or something?

[mental trellis]

If you want some feedback, I don't think your portraits suit your game very well.

[copper hawk]

All placeholders. They are AI Generated

[mental trellis]

I dunno, from the text, I was expecting more pixel art stuff.

[mental trellis]

Fair enough!

[lofty rapids]

wdym, did you check your click events ?

[copper hawk]

will show what it means in a video

just need tor ecord it

it like shows itself multiple times

[lofty rapids]

are you clicking in that video ?

[zealous moth]

I have a map of int::vector3
It's an index to location map.
I want to add an index with a new vector in between 2 indices.
How would you do it?
I use the following with some private variables:
https://blueprintue.com/blueprint/171-rd39/

[copper hawk]

yes

[copper hawk]

whenever it gets a little darker is when i click

[lofty rapids]

you only create it and display it in the level bp ?

[copper hawk]

believe so, dont know where else it would be be getting created

[trim matrix]

Tools->Find in Blueprints just to be sure

type the widget name there

[copper hawk]

ah, it was. thanks @trim matrix didnt know that tool existed

very helpful tool

[trim matrix]

remove it from the other places 🙂

[copper hawk]

yep, works flawlessly now

thanks guys

[dawn gazelle]

That's not really how maps work. They're not stored as an ordered list like an array. Could you not use an array in this situation to begin with if all you're doing is using an index associated to the vector?

[zealous moth]

no, because it is a real index :/ I have to refer to the vectors using that index in other logic

like there's an order to it

[dawn gazelle]

Could you not look up the vector by the index it is in, in the array?

(If you were to use an array instead)

[zealous moth]

looking into it

[zealous moth]

Assuming I could add it in the array, how would i add it in between indices?

[dawn gazelle]

I believe it is "Insert"

you feed in the new index and the vector you want to put in there.

Everything else should shift down.

If you were to insert at 2, what was at index 2 would shift to 3, 3 to 4, etc.

[zealous moth]

hmmmmmmmmmmm i am trying to figure out if i can make it into an array only

[carmine palm]

Question because this is working but now how I want it lol. Its not working for player facing the item. Its working if player is in line with the item no matter direction.

Highlights loot object when player is within range of it (IE overlaps) and on end overlap dehighlights, but I want it to only highlight if player is looking at it, and if they change direction away from it then it unhighlighs

So not sure how to properly test looking at object

My line trace is currently just checking if they are in line

[trim matrix]

for end do camera location + (camera forward vector * maxInteractionDistance) 🤠

for the start, just the camera location

[carmine palm]

so other actor->get camera or whatever-> get location for start

yea do did actor->getComponentByClass(Camera Component)->getWorldLocation

well in BP but yea

[trim matrix]

GetPlayerCameraManager->GetCameraViewPoint, use the location from that as Start. From the rotation do ->GetForwardVector * 1000 <== 1000 is the max interaction distance. Then add together the multiplied forward vector with the camera location from view point, and plug that into End

[plush hornet]

evening all, How would I save a players rotation when entering a new level. For example if he is facing up how do I get them to still be facing up when entering the new level. My charecters a 3rd person actor btw. I presume you would save the info in a game instance? Thanks

[trim matrix]

GI, yep

[dawn gazelle]

If you want to be able to turn on and off the post process based on whether the player is looking at the item, you'd need to use Actor Overlap Begin, Acor Overlap End, and Tick.

Assuming this is a single player game...
On begin overlap, you can verify it's your player character overlapping by casting other actor to your character class, if so, set a bool named "Player Overlapping" to true.
On end overlap, do the same but set the bool false.
On tick, check if the Player Overlapping bool is true and if so, you can perform your trace logic. After the true on your trace, you want to do something like the below. The "Target" in this case would be the player charater. The dot product should be > 0.5 if the chest is "in front of" the player character, so you can plug this into a > check and branch it. If true, set your post process material on. If false, set it off.

[carmine palm]

yeahighlight works just fine

its just 3rd person and want to make sure player character is facing it

so I need t break the hit result then

and make sure its my chest yea?

[fringe coral]

I tried removing a child widget with "Remove Widget" but the buttons on the parent widget keep needing an extra click for some reason. Why is this and how can I remove this nuisance of a UX problem?

[lunar sleet]

Are you looking for remove from parent ?

[fringe coral]

Yeah, sorry. That's what I meant.

[lofty rapids]

mabe you didnt focus the widget ?

[trim matrix]

show code

[plush hornet]

Can you eloborate please, the way im doing it isn't working

[lunar sleet]

Get the rotation before you change level, cache it in a var, set the rotation after level load?

How are you doing it ?

[plush hornet]

Getting the control rotation from my player charecter and saving in a rotator variable in game instance, when level loads, getting variable and setting my actor rotation

Its not working though

[lunar sleet]

Debug. Use breakpoints or print or watch value to see what actually comes through

Idk if it’s control rotation you want tho

I’d imagine world

[trim matrix]

you too should show code 🙂

[fringe coral]

shouldn't that be in the C++ channel?

[lunar sleet]

Blueprint visual scripting is also code

[fringe coral]

I'm an artist so I just find it hard to see them as the same thing.

[lunar sleet]

Also #umg might be able to help if you still have widget issues

[lunar sleet]

You’ll get used to it

[plush hornet]

The important parts Iv'e highlighted in Red

[lunar sleet]

Are any of your casts failing?

Are those prints working ?

[plush hornet]

This is what im getting

[carmine palm]

ugh

Its facing that way every time lol

[plush hornet]

it doesnt seem to be saving the variable

even though it says true?

[lunar sleet]

See docs on control rotation, try it with get actor rotation instead

[plush hornet]

tried doesnt work

Not sure if its because im using a papersprite actor?

Control movement works pretty much the same though so unsure whats going on

[lunar sleet]

Maybe, but your get control rotation appears to be returning 0,0,0

You can double check by setting a breakpoint on that set player rot then when it drops to it go and hover over the output of get control rotation

[lofty rapids]

get controller, get control rotation

is what worked for me

[ornate kraken]

Hello. Does someone know if a node like create material instance but with render targets exist in BP?

[carmine palm]

fixed the trace but

for some reason its not detecting the collision on the static mesh according to he uh

[plush hornet]

Thanks, doesn't work for me unfortunately. I think its more because my actor is a 2d sprite, the movement is slightly different

[carmine palm]

any idea neo

[lunar sleet]

You really need to finish your sentences lol. Then you have a collision issue

Also you’re using == so idk if that’s returning false

[carmine palm]

can you not collide with static mesh components?

[lunar sleet]

You can

You just have to set the collision properly

[carmine palm]

oh

[lunar sleet]

And use casts not ==

For the actor side anyway

[carmine palm]

what collision would it need

Need player to not be able to walk through it, but need the line to hit lol

[lunar sleet]

You can make custom collision channels and set your Collision to custom so you can block the ones you want

[brisk merlin]

Anyone Know if it is possible to use or PILOT a ( Camera actor ) in game as the main playable character. In the editor you just right click and can pilot the camera, I would imagine that it would have to be manually configured to do this for "ingame." if so how?

[carmine palm]

yea im looking at that now

what is the line trace considered for collision? Do you know?

[hollow pond]

replace the player character with a Pawn that uses FloatingPawnMovement. set up the controls right and it should work just like piloting a camera in editor does

[brisk merlin]

That's what I thought, thanks for the quick tip! and verification

[dawn gazelle]

Just going to put this here for @carmine palm

[carmine palm]

thanks brudda

are event ticks heavy (optimization wise)

[dawn gazelle]

If you want to be able to detect if the player looks away, you need to use tick.

[carmine palm]

Figured

[dawn gazelle]

And for something like this, it's not very costly... And it's turning tick on and off when needed.

[carmine palm]

oh so you are only turning tick on while in overlap

I see it now

didn't know you could do that

Bruh

I know why

It wasnt working

I had hitactor instead of hit component.

atleast I think thats why

[ruby tendon]

if i cast an action to an enemy that is a parent, does the child also take that action

might be a really dumb question

[plush hornet]

I figured it out🤗

Same principle as get charecter rotation but you have to use the Vector 2D variable instead

not a rotator variable

Not sure if this is what you mean but ......Use a post process volume and set it to unbound so it covers the level. Mess with the options below in the volume. It will fade everything in the distance but keep everything around the player clear.

its the easiest way ive found tbh

[dawn gazelle]

You don't cast actions. You call functions.
If you have a reference to an object that you know is a child class, but are casting to the parent class and are calling a function that exists on the parent, it will execute whatever you've defined in the child class to execute.

If you don't override the function in the child class, it'll execute it as defined in the parent.

[carmine palm]

success lol

now I just have to do your tick thing

[gentle steppe]

does anyone have a template for free or anything which has a pickup system with some items, which when you look at them, it has an interaction widget which says something like “[E] Apple” or whatever keybind and item. i’m trying to remake one from DayZ but i don’t know how to get a border to be the same length as the text of the item

[lunar sleet]

For the first part, no, you’ll need to write your own code. For the widget border thing, try #umg

[carmine palm]

not sure if this is visible enough

New laptop. Used to 49 inch monitor lmao

Just figred out these reroute nodes. They are so convenient lol

how do you add comments or the border behind code

[lunar sleet]

Press C

[carmine palm]

thanks bruh

[reef badge]

i'm wanting to attach a point light to my character, and add particle effects to a double jump, similar to what is pictured. Only I want the light to be tied to a health/stamina bar. Tips on how I could get started prototyping something like this?

[versed sun]

Break it down into parts
Do you have a Health system made?
Do you have a Light setup and what are you changing about the light?
Do you have a Character?
What do you have so far besides an idea ?

[timid rune]

Does anyone know why when I check to see if my forward vector is -1 it will always return 0 even though it is prints the correct value in a print string

[lunar sleet]

How are you checking it

[faint pasture]

why would a vector ever be -1?

that doesn't make sense

[timid rune]

im splitting it into each axis and it prints -1.0 in the printstring

[faint pasture]

show your code

what exactly are you checking?

[versed sun]

try nearly equal

[carmine palm]

how the fuck

is your node boxes square

are*

[timid rune]

That seemed to work thanks!

[timid rune]

What causes that? Just Curious

[versed sun]

-1.0 is rounded

[timid rune]

@carmine palmChange the Images in the folders: C:\Program Files\Epic Games\UE_5.2\Engine\Content\Editor\Slate (Graph and Old)

[versed sun]

its actually -1.0000001

or something

[carmine palm]

oh nice

ty

[versed sun]

Use Nearly Equal with floats to save headache

[timid rune]

@carmine palmIf you want i can send the folders I already changed so you can just drop them in

[carmine palm]

Sure that would be awesome

[timid rune]

Just messaged you@carmine palm

[carmine palm]

Thanks bud

[timid rune]

NP

[carmine palm]

How can I remove the Target[self] shit from my function

oh pure function

sick

[reef badge]

@versed sun I don't have a health system yet. what i'm wanting to change about the light would be the attenuation radius and the intensity, as well as mayble the particle sphere radius. but i'm sure i could find a video on how to setup a health bar, and try to figure out how to make the light work with it.

[crystal crown]

How can i access animbp's without casting

[mental trellis]

Why wouldn't you want to do that?

[crystal crown]

i don't want them to be loaded all the time

[mental trellis]

Add an interface.

[crystal crown]

i have

[mental trellis]

Cast to the interface.

[crystal crown]

didn't know i could use interfaces for animbp, mb

[mental trellis]

They're all uobjects.

[versed sun]

Ok, I would start with a way to Lerp from the Dimmest to Brightest light settings you want so...
0 would be dim/min
.5 would be halfway
1 would be bright/max

[lunar sleet]

Once loaded, it stays loaded tho

I don’t think interfaces will change that?

[mental trellis]

That's not true.

If it stops being referenced, it will eventually get unloaded.

[lunar sleet]

As opposed to casting?

[mental trellis]

A cast will tie the two bps together, which potentially ties whatever bp he is talking about to the assets in teh anim bp.

[lunar sleet]

Ah I c what you mean

That’s interesting, didn’t know you can use interfaces like that

[mental trellis]

That's kind of the main use of them in bp

[lunar sleet]

Nice

[thin panther]

A cast to an unloaded object in BP does load the CDO though, which is retained for the duration of the play session

The downside of this is if the BP has asset refs, as they will remain loaded. Base classes make this a non issue.

Casting in c++ is free from this issue, as the CDO in cpp land is loaded anyway. Which is also why you don't asset ref in c++

[mental trellis]

Of course, if it's the main character's anim bp and it's the main character class, it matters not a sausage.

[crystal crown]

nah i'm trying to keep my character and vehicle separate

[proper vigil]

Duplicated this MetaHuman code to run different dialogue when the Objective Text is something different. Different vars and a different new text for the Objective after the second event run. The one that says Test Text is the second one and the one that is first has the text change to Visit Cemetery. For some reason, they both result in the objective becoming Test Text.

[mental trellis]

That's probably a good idea, Extile.

[versed sun]

Once you have the 0-1 lighting working , your health works in a similar way...
0 is no health/Dead
.5 is %50 health
1 is full health
then you can change the light settings whenever you change health

[carmine palm]

For this function is there an array function that is just get object (index) so I dont have to foreach?

[fringe coral]

Ok, so forget "remove from parent" for right now. My question for this little experiment I'm doing is: how can I destroy a ui widget using only blueprints? If "remove from parent" is the only way then how do I remove all effects so that interacting with underlying widgets doesn't require an extra mouse click?

[proper vigil]

Here is the function that makes it become Test Text.

The one above is the Visit Cemetery one.

[versed sun]

are you asking for this ?

[verbal kayak]

why cascade particle AnimTrailData does not work in unreal 5.1?

[carmine palm]

I cant even see that ryck

[versed sun]

2nd pic

[carmine palm]

I have one player (single player game). Just need to get the overlap actor

yea get

that works

[versed sun]

yes, Get(0) will work

[carmine palm]

ty

All working now

It's all pretty now lol

[versed sun]

where's the Uncommon ?

[crystal crown]

How do i make this into an interface?

[faint pasture]

Why are you talking to the animBP instead of animBP just reading from the actor?

[crystal crown]

I probably don't understand your question but i need the character to open the vehicle door before it's possessed and toggle handik on/off before/after possession

[faint pasture]

what class is this code in?

[crystal crown]

vehicle

[carmine palm]

Through BP is there a way to end the on overlap event from being called

found it lol

[crystal crown]

also i don't want to cast stupid stuff like this

[carmine palm]

Question again

Going to make this a function/bp I can just drop on multiple chests and just have a variable on them to change gold value/treasure array

Is there a way to get whatever collision component self has?

more so. is there a getComponentByClass that can have a group of objects as a class type/filter

sloppy but got it lmao

[magic kite]

I don't understand how enhanced inputs should work in 5.3 followed the guides and tuts online most of them out of date and do not work any more and the client doesn't get the local controller enhanced input added for some reason? what am I missing thank you 🙂

[crystal crown]

#enhanced-input-system Also set inputs in player controller

[edgy ingot]

Its still the same ever since it ckme out. if it doesnt work, chances are you didnt do it correctly.

You mention client, so you probably doing multiplayer.

And chances are you are mapping in begin play, which is TOO EARLY for client. You want to map the input on posses not begin play.

Thats why it work for your server and not client.

[carmine palm]

Another noob question lol

So I had made that bp on my object

but I want to make it usable as a drop on bp for all my chest objects so I don't have to re-write it for everyone, and then have an exposed array I can just change loot on.

and I have an interact interface on the object, but I can't add it to my new BP (guessing it cant have interfaces)? and also if not can I grab the interface from the object and grab the event

[edgy ingot]

If your new bp is a child of a bp that has the interface, it will inherit the interface

[carmine palm]

issue is

the bp I need to call the event

to use my other functions

[edgy ingot]

I dont see the issue

[carmine palm]

do I have to add the bp to the object first

before it will show up then?

[edgy ingot]

Not following you sorry

You are making an interactable object. Keep it straight forward

Make a base class for interactable objects

Make a base function called interacted

[carmine palm]

BpChestSmall - has the mesh/trigger box on it.

Want to make a base BP to just be able to drop on it.

[edgy ingot]

You can then have different functionalities if needed in child classes, eg chest or door

Or even light switch

[carmine palm]

on the player?

[edgy ingot]

Not sure what you "dropping"

[carmine palm]

interact class

?

[edgy ingot]

Child classes inherit their parent functions

And events and interface

I will still suggest the same thing

#blueprint message

[carmine palm]

okay

I see now

or not

yea I got it now ish

[magic kite]

thank you I had a feeling I needed to do it on possess thank you very much

[dense jacinth]

If I make a base_enemy bp, and then make all enemies a child bp of the base_enemy bp, how would I check if a reference to an actor is a child of base_enemy? I know there has to be a way to do this easily in BPs but it has somehow evaded my google searches

[ionic crescent]

get class and if its = to base class

[dawn gazelle]

You can cast the reference you have to base_enemy.

If the cast succeeds, it's a base_enemy.

[radiant cape]

New to programming/visual, trying to understand all of these words in seeing in tutorials...

If you have a parent class that's never used in the world called Pawn, and 2 classes that are its children that are spawned in the world...
Is the parent class in this case what programmers call an abstract class?

blueprints is probably a bad introduction lol

[dawn gazelle]

An abstract class is something that you can use as a definition for child classes but not actually spawn or "use". Pawn isn't technically an abstract class as it's not defined as such in its UCLASS() specifier:

UCLASS(config=Game, BlueprintType, Blueprintable, hideCategories=(Navigation), meta=(ShortTooltip="A Pawn is an actor that can be 'possessed' and receive input from a controller."))

If it was abstract class, it would say "Abstract" in there.

[dense jacinth]

Ah it works that way? I didnt realize children classes = parent class

ty 👀

[edgy ingot]

I would suggest to look at key component of object oriented programming. Inheritance is parts of it

[edgy ginkgo]

making a three player game as seen here with 3 spawn points. Currently with 3 spawn points players randomly spawn at different points how can I make the spawn point determine which player spawns there

[autumn bane]

if i have a blueprint Set and i destroy 2 of the actors inside it, whats the behavior once GC runs?

do i just have 1 element (null) left?

[marsh pilot]

https://blueprintue.com/blueprint/dvn-rvhl/
Anyone know why this nested for loop is giving me an infinite loop?

[edgy ingot]

U got a cursed pin that goes all the way back to the loop

I never go full circle with exec pin

W e u do workout your logic without cursed pin

[marsh pilot]

Ah okay, I suppose I don't know how a nested for loop works in blueprints apparently. I'll do more digging into that

[edgy ingot]

Its not about nested loop

But the way ur pin goes

[marsh pilot]

Oh I see what you mean, thank you

[dawn gazelle]

Override ChoosePlayerStart in the game mode and use some logic to determine which player start should be used. You'll likely need to do a "Get All Actors of Class" and select the playerstarts class, which then gives you the array of playerstarts. If you add tags to the playerstarts, you can use those to help determine which one you're referencing specifically.

[west yoke]

Since we can't iterate over sets, is it better to just use an array and AddUnique and Remove Item or use a set and conver to array to iterate?

[slate fable]

quick question! When I make a blueprint>Character, why is the capsule component halfway in the ground? is there a way to fix this to where the whole capsule is above the ground?

[tawdry surge]

@west yoke it depends what you're doing. Sets are faster at look ups, so if you just need to check if something is in the container use that. If you need to iterate then just use an array

@slate fable No. The capsule root is in the center and you can't move it

[slate fable]

@tawdry surge is there a reason its stuck like that? I don't think its supposed to be like that? did I mess something up somehow? 😕

@tawdry surge I tried adjusting the halfheight to try to fix it but im at a loss at this point, it just makes the capsule taller instead of bringing it up

[elder lodge]

it's fine

[slate fable]

in this case I just put the mesh I'm going to use inside the capsule under the ground level? will it affect anything in the game? I'm using this character as a monster and will be attempting to give it some AI like chasing attacking etc.

[zealous moth]

@dawn gazelle that solved it!! 😄

[slate fable]

i think i got it figured out to some degree thanks @tawdry surge @elder lodge

[fallen drum]

GREETINGS
can someone explain to me why my selected option is not being set? i essentially just want it to display the resolution of the player's screen in the combo box before they select a resolution

[modest tinsel]

Whats causing this error? sorry to ask! 🙂

[fallen drum]

i want this to show the resolution (int text) when the game starts before the user selects a resolution

[dawn gazelle]

You're attempting to access the hit result through an RPC which didn't actually run the trace. Don't cross execution paths.

[dawn gazelle]

You need to add it as an option to begin with.

[modest tinsel]

So how would I fix that I think I know what you mean

[fallen drum]

oh yeah my bad i did yet it still doesnt work (sorry for not showing initally)

[dawn gazelle]

Either
A) have everyone run their own trace in the multicast event to get their own reference to the actor.
B) pass reference to the trace actor's hit results through the multicast (add a property to the event and pass it)
Mind you I don't think you can have component movement actually replicated like this... I'm not sure calling stop on clients would work.

[dawn gazelle]

When did you do this? You're doing the set option on construct.

[fallen drum]

so i have to put the set selected option after i added all the options?

[dawn gazelle]

If you don't add the option, you can't set the option to it if it's not in the list of options.

[fallen drum]

ohhh i see now i figured it out. i used the viewport size which wasnt in the list so i switched to get user settings and got the resolution from there

thanks for the help

[elder lodge]

this seems to be zeroing the velocity instead of inheriting it after detaching from a body; am I misunderstanding the flow here?

[carmine palm]

Having hard time mathing

what would you do to get a position in front of player say 10 ft with trace

forward facing vector * something?

[modest tinsel]

Are my anims playing twice?

Why do these play twice in client?

[elder lodge]

Yeah, the forward vector

[carmine palm]

my start works. I just cant get my end

I have actorForwardVecotr * MaxInteraction (val is 300)

which is not working obviously

[dawn gazelle]

ActorLocation for start point.
(ActorForwardVector * Distance) + ActorLocation for end point.

[carmine palm]

my hero

[dawn gazelle]

Notifies shouldn't require replication like this. The montage itself can trigger the notify locally when the montage is playing on any clients which can then be used to playback the sounds or whatever you want from that notify.

[elder lodge]

I found that also "Draw Debug Arrow" helped me figure things out a lot

[hazy dock]

Ok, I don't know where else on here to ask about this. I'm trying to automatically do something after a Bink video finishes. So I'm loading it up and then registering the On Reached End event. The problem is it seems to trigger just before the player actually starts playing instead of at the end of it playing... I've read through the C++ and this is where it's causing it:

{
    // Check for if we should issue the reached end event
    if (bnk && !reached_end && !IsPlaying() && !IsPaused() && !IsLooping()) 
    {
        OnMediaReachedEnd.Broadcast();
        reached_end = true;
        //MediaEvent.Broadcast(EMediaEvent::PlaybackEndReached);
    }

Anyone run into this? Any ideas how to keep it from ending before it begins?

this is basically the blueprint code:

I have a lot of stuff going on around that code to set up things like brushes for the UI, load various other things while it's going to be playing, etc., but that's the code I'm running on the bink media player

[livid olive]

hello! I've been studying Unreal recently. I'm trying to use voice chat within Unreal using Discord. Where can I find that information?

[hazy dock]

Well... for anyone interested I found that if I set it to looping true and then delay a bit after the event set up and set it to looping false again it works... pretty bass ackward, but it's working... Anyone have a better way around this or know what I'm doing wrong to make it so that I have to do this? I assume it's something I'm doing...

[hazy dock]

seems to be a plugin: https://www.unrealengine.com/marketplace/en-US/product/game-sdk-features?sessionInvalidated=true

[wise raven]

does "ignore actor when moving" node disable collisions between two actors?

[surreal peak]

@hazy dock fyi that's not for sale and mostly deprecated from Discord s side

[hazy dock]

ooh, was just trying to help quickly, but looks like you are out of luck, at least with the GameSDK

[digital palm]

I would like to draw a line from the center to the middle of one side. I know I can use actor bounding box but can't resolve it. Any example?

[thin cradle]

is there any blueprint event for when 2 objects stop physically colliding? like how hit is called when they start colliding

power?

all good

[serene crater]

Is there a parituclar reason why a BP with parent class APivotTransformGizmo can't be spawned as an actor in the world?

[halcyon vapor]

If the get node is plugged in to an empty array what is the output?

ah so if a few hundred run every 0.5 seconds, is it noticeable?

alright nice

but as long as there aren't many instances active at the same time it's good right?

alright, the code I'm making is highly unusual, so I couldn't expect it any other way

I'm afraid for my very specific case that won't be possible, however functions that run on tick are rare and small, so that's as much as I can do

[wild crater]

Yup, it's called switch

[unreal berry]

Guys im finally done with my beginplay logic💀

Now i still needa do some event tick logic wish me luck

[wild crater]

I would suggest splitting up your code more into functions and trying to see the patterns to avoid duplication. If you can, replace any two (or more) pieces of similar logic by making one function and settling the differences with parameters, then call the function 2 (or whatever the amount) of times with different parameters.

[unreal berry]

Yeah but these are mostly already functions called in a diffirent collapsed node

Like movement is done somewhere else

[versed sun]

Just a FYI, if that graph is visible when you are playing , you might get a FPS drop

[unreal berry]

Yeah true, its pretty big

Would i need to use more graphs for the loose functions?

[versed sun]

nah , just make sure you are on a different BP or tab

[edgy ingot]

Look for select nodes as well

The return value will depend on the input value

There is switch and there is select nodes, both have different usses

Say u want to play sound depending on an enum or int. Then select is the obvious choice

[nova oxide]

is there an easy way to make async loaded actor classes persist in memory?

[mental trellis]

Assign the class to a variable in an active object.

Someone mentioned the yesterday that cdos stay in memory perpetually? Idk

[nova oxide]

currently tested that did not work:

1. i added the reference to a map as a key only in GameMode
2. i added the reference to a map as both key and value in GameMode
3. i added the reference directly to a variable in GameMode
4. first one but in an actor on level
5. second one but in an actor on level
6. third one but in an actor on level

all of these got lost after waiting for garbage collection

[edgy ingot]

Try game instance?

@nova oxide

[nova oxide]

i suppose also relevant is that this only happens in a build, not in editor

[edgy ingot]

Because in editor once loaded always loaded

But in build when you transition level, a lot of things get destroyed and gced

If your outer is a presistence object, eg game instance. You should be fine

[nova oxide]

they're fine to be destroyed when changing levels, but they are currently getting destroyed without as well

[edgy ingot]

How do you load the class?

If they have valid outer, they shouldnt be destroyed

[nova oxide]

https://i.gyazo.com/4a34cd35babce0649c9f5be9cdd58e0b.png

they're valid for some time, but then they get cleared out

[edgy ingot]

R u loading class or asset?
