blueprint

[cyan bone]

ahh exactly

but that means if i move the camera around

then the thing will be off right?

it wont fade in against the background

[versed sun]

thats part C

I was thing a 2nd check in Event disparcher that can fire a "Retake Photo" that when the angle changes too much

[cyan bone]

I see but there must be somthing of a fade into the background. Like in photoshop when you cut the background and then do a gradient into the transparent

the issue is the sky

if green (grass) goes into the sky then its over

if i could take a picture of them without background as a png

else it will need many pictures ticking

and thats not good

[astral stratus]

love having to scrap my entire inventory system and start over 🙂

[versed sun]

is it top down ?

or more of a floating camera

[cyan bone]

you mean if i can roam around like in Total war or if its more like Age of Empires?

[versed sun]

yes

[cyan bone]

for now its more like age of empires

but you can zoom in a lot

im still undecided on this

because the total war style gives more fancy zooms

and you can look in the horizon and so

[versed sun]

then you might need to retake pics when the angle changes too much

[cyan bone]

i made a blueprint that makes a solid out of a convex hull from my soldiers batallion positions. So it takes their wrap, then converts it into a solid. A procedural static mesh.

[cyan bone]

yup i think that will be messy

because of the sky

and the grass. It would need a tick picture. And if i take a picture, then the soldiers must be there anyways, right?

so maybe the idea of the cube would be better in this respect?

[versed sun]

or... Top down Scene Cap Pic, put on a Decal ?

i dont know the scale of how far things are

[cyan bone]

its a huge battlefield. I tested 50k+ units the other day

thank you ryckoshae

this brainstorming was very important

[versed sun]

You got some htings to think about and test

Maybe even a particle system? i havnt used them much but just a thought

[ripe pier]

Hello everyone, want to make a custom blueprint where I can change the colour of the new default UE5 car. How can I go about it?

I know that I can change the material colour with the tint feature on the body but I dont know how to implement that into a UI with blueprints

[topaz badger]

Anyone know why Im getting this error? It started happening ever since i move to ue5 but will go away and come back randomly. If i restarted it would compile fine.

[echo mist]

Can I add "TriggerBase" as a component into BP?
I want BP_A to have reference to BP_B trigger collision, but the only thing I can add is Sphere/Box/Capsule Collision component and I didn't find a way how to reference default Collision component no matter the shape just like TriggerBase can contain Box/Sphere/Capsule Trigger

[faint pasture]

Why would gamemode have anything to do with this?

Just have some variable on pawn or on playerstate with a repnotify that adjust the material parameter or swaps the material out

[lime moat]

Hey ya'll, i'm having an issue trying to get a SetText component to update its text in the editor. I am simply wanting to know what index each item is in editor. Heres a screenshot of what I have in my construction script. Currently, the setText is rendering out the last index for all of my BP actors I have in the map. I can see each item's index in the exposed variable, and in print string on begin play, so it's odd that setText isn't updating correctly.

edit, figured out my problem. I wasn't using the RenderText from the array

[glass stump]

How do I save the 'state' of a BP?

I guess there must be a variable for it I guess.

[lime moat]

make a new BP of the save type class. send any variables you want saved to that save class. Then you can use node "create save game", and then "save game to slot"

[worthy carbon]

Hey everyone i have an inventory system in my ue5 project but i'm missing the part where i click on 1/2/3/4 or 5 the item has to attach to the character... how do i set that up?

[glass stump]

Would I need to use an array variable to save the state of each instance of the object within the level though?

As there's multiple of these objects, each with a different state which changes depending on the players actions, and I thought that if I do it straight up like this it'll just change all of them to the same thing, but I might just be misunderstanding how it works.

[lime moat]

You can save array elements, i'm not sure if that's what you'll need for your project though.

[lime moat]

if your states are all saved in an array, you should just be able to send that array to the save class

[glass stump]

ah, i wasn't sure because i used an array system to load (or rather not load) destroyed enemies today and that worked fine, been trying to update it to set the state of these other BPs too.

but i just realised i can actually directly create a variable of the exact state variable in the savegameobj, didn't know i could do that. XD just need to figure out how to set it to load each BP in the state set by the player in the game when saved atm.

[lime moat]

If your array is accurate, using a for each loop to set whatever values you need on begin play should be good. You can cast directly to save game to access the array

[glass stump]

Ah, thank you I'll try this out! :) I felt like I was missing something so hopefully this is it. :)

[lime moat]

Good luck! 😄

[tawdry surge]

I'm having a hard time pinning down an issue with some widget components.
I have two widgets in world space I'm using for interaction spots. They work fine but in the level (And only in the level) they render black (top picture)
BP editor viewport, widget editor, and material editor all look fine.(bottom picture)
Anyone have any idea why this could be happening?

[elder mango]

what's the best for good collision?

[tight schooner]

There are tradeoffs. Collision primitives like spheres and boxes and capsules are inexpensive to test against. Complex collision is expensive. If you're going to have A LOT of collisions on a complex surface, it might noticeably impact the game thread

Sometimes you need the precision of complex, like on a spline road that vehicles will drive over

But otherwise use simple when possible

[pseudo wedge]

im trying to get ureals top-down template to work using the other event tick method, but the player literally doesnt move at all and just stands still

[viscid hinge]

why is it flickering what do i work on

[pseudo wedge]

im a huge fucking dumbass nevermind

[tight schooner]

@viscid hinge is your hit location exactly on the boundary of a grid snap?

Maybe offset the hit location by the hit surface normal

[viscid hinge]

Well I kinda fixed it but there is a problem, when I trace from a certain side the object gets placed inside the existing object

[tight schooner]

How did you fix the original issue?

Asking in case the new issue is related to that

[viscid hinge]

I broke the hit loc to a 3f and snapped each invudal one, but now there is a new problem

Il show you one sec

[tight schooner]

Hmm. My thinking is the hit locations you're getting are straddling the line between two grid points and you need a way to disambiguate that

Adding the surface normal of the hit to the hit location should be enough in my imagination

Cuz that'll offset it away from the traced surface

Which is where you actually want the new block to go

[viscid hinge]

hope this helps

i want a way to snap it to a face? is it possibke

[tight schooner]

Yeah try my suggestion above

Hit location + hit impact normal

Then vector snapped to grid

If it doesn't work try multiplying hit impact normal by 10

Or use a Draw Debug Sphere node to visualize what's happening

[viscid hinge]

like this?

it works well but there is a new problem

it works well tho

can you please also explain to me what this did to make it work? thank you

[tight schooner]

A "normal" vector is a vector with a length of 1 that points in a direction. For example, the "actor forward vector" in your line trace screenshot is a normal that points in the direction the actor is facing

The impact normal... If I recall correctly... Is what's more commonly called a surface normal

It points away from the surface

So by adding the surface normal to the hit location, you're offsetting the location away from the surface by one Unreal Unit (cm)

And that's enough to disambiguate the grid location you're looking for

[viscid hinge]

what ab this problem

i mean, its good for now i do thank you alot, i wish it wouldnt snap to corners tho

[tight schooner]

Corners? Jeez. I don't have a great solution for that off the top of my head

Other than doing a whole lot of conditional line traces to test whether there's

1. a surface near the cursor

and 2. an empty grid space on the backside

[viscid hinge]

allright no problem thank you for your soultion

btw again, is there a way to snap objects to box collisions on Static meshes instead of grids?

[tight schooner]

Like place a thing on a surface without snapping? Basically do the same line trace and "impact normal" offset, but skip the grid snap part, and have to figure out how much offsetting off of the surface you need. If you have a spawned object, you can get the "bounds" of the object, which'll help you figure that out if the placable objects aren't all the same size.

If they are the same 100³ size then you basically need 50 offset.

[digital palm]

Hey, I'm trying to create a bed actor. This purpose is just let the character sleeping. I want to change also the input. I would like to only have the 'e' button could be pressed to exit the bed, and then if 'e' pressed, it gives back all inputs. How can I do that? I tried to disable input but it's disable everything (oh and its multiplayer)

[viscid hinge]

Is there any video that can help me with this or doc

[tight schooner]

Sorry I don't have one offhand. I never tried making this type of game @viscid hinge

[viscid hinge]

What can I search up tho, I found nothing useful

[tight schooner]

Idk the proper jargon either 😅
Building system? "Minecraft"?

I know there are a lot of "make minecraft in UE" type things on the web. Can't vouch for any of them though.

Probably on the UE marketplace as well

[viscid hinge]

Building system has only 3 proper tutorials, once is something I don’t want, second has a part of code I can’t do/ add wish if you could help me with it it will help bec he shows how to snap to boxes,

And no I’m not making “Minecraft” it’s a realstic sandbox building game, not close to mc but inspired by it

I will show you the part I’m stuck at

https://youtu.be/Z8u1EUJxfOI

5:10

I can’t find anything called set camera

[desert juniper]

Building system has only 3 proper tutorials
the series has 37 videos
https://www.youtube.com/watch?v=AgXbXoSRqyI&list=PLGm9gBuuMTeuLQythBu61WK7qO31RRH7l&index=1

[viscid hinge]

Yes I’m talking 3 as 3 Creators they have proper vids

[desert juniper]

The camera they're talking about exists on the BuildComponent

it's just a variable of type Camera

if you don't have one, then you forgot to create it whenever he did

[viscid hinge]

Thank you I will try

[astral stratus]

hey guys im following a tutorial on youtube how do i find this node?

https://gyazo.com/627df8bbe0be1f96a1f5b0b8a5bc0847

[tight schooner]

Set by ref? Might only be available inside a function graph but not sure

In an event graph you can just set a variable directly

[astral stratus]

im inside a function graph right now and cannot find this for the life of me

[viscid hinge]

is there a way to make the flying not slipery like that, like when i stop pressing to go up it stops instead of gliding

[tight schooner]

@astral stratus does your function have a "pass by ref" input? Try dragging the diamond shaped pin out and search for "set"

[astral stratus]

im actually not sure why im not seeing that node

this is the tutorial im following in at 5:54

https://www.youtube.com/watch?v=cqiZ7x02Jds

any ideas?

[pulsar path]

idk but just a 'set variable' (that is of type integer) will work just the same

oh thats interesting

it might be a struct thing, you can try dragging off the struct?

[astral stratus]

so drag off quantity and try to set the integer ref?

from the struct break?

[pulsar path]

'set by -ref var' is what its called

yeah

[astral stratus]

you are a king ❤️

[pulsar path]

np

[astral stratus]

any reason why i couldnt find the set ref though from typing it?

[pulsar path]

you actually can
i only just found out about this
its just called set by -ref var and it changes to whatever type of variable you plug into it

[astral stratus]

ohhhh ok interesting

ty again

[pulsar path]

on released, set velocity to 0. you could do this to just set the vertical velocity in case the player is still moving horizontally when they stop going up

i believe that should work ™️

if not you could just grab the velocity, and apply an impulse thats the opposite of it, effectively stopping movement

[viscid hinge]

thank you

[astral stratus]

love how helpful everyone is in here

[pulsar path]

its weird being on the other end of it, i got a lot of help from here when i was still learning

still kinda learning tbh, always gotta be learning

[astral stratus]

yeah im learning as I go this tutorial im following explains everything fairly well

[foggy escarp]

Oh I had no idea you could do this.
I guess it's similar to setting any other stuct variable by ref.

[gentle urchin]

Isnt this the macro node set integer?

[fervent bramble]

Not entirely sure where to ask for help with this.. I'm trying to recreate a similar camera system to this, I already have a system setup to switch between cameras, I'm just not entirely sure how to have the camera sorta float with you as you go down a hallway if that makes sense? Any help would be greatly appreciated

[surreal peak]

You can do that using splines for example

[rough warren]

Hey guys, I'm just wondering how I might change which direction my attach to socket is

Is there a way I could create a socket attachment on the item and then just attach socket to socket maybe?

[surreal peak]

What stops you from just rotating the socket on your skeleton?

[rough warren]

I rotate it and it just doesn't change

[shadow sentinel]

Hello everyone. My friend has just finished another year of programming at a university and he's looking around for a good place to start learning Blueprints so that he can eventually make his own, small souls-like clone. Does anyone know of any decent tutorials that would be a good place to start for someone with no prior UE knowledge? Thanks! 😄

[rough warren]

Also, I don't want to rotate it on the player because I'm going to have multiple items

[surreal peak]

I mean theoretically you just need to make sure your times follow the same orientation

But if you want to use this you can just use the second socket on the item itself to drive the offset params on the attach node

[worthy carbon]

Hey everyone i have an inventory system in my ue5 project but i'm missing the part where i click on 1/2/3/4 or 5 the item has to attach to the character... how do i set that up?

[rough warren]

Would you by chance know how I might set a delay for "swinging" or clicking?

[umbral merlin]

Hi.
Me and my team trying to make a FPS game to shoot words as bullet.
Is there any ways to input Python output (Or Array or just print() ) to UE4's blueprint? Because we use Python to recongnize audio and convert to text

[icy dragon]

Don't use Python.

[umbral merlin]

I am a new guy who joined UE4 and programing.
I just want a function can recongnize audio and transfer to text. (Japanese as main)
Any suggestions?

[icy dragon]

Use speech recognition library that's made with C/C++, then integrate it to Unreal C++ as plugin

(Make sure the library is not under copyleft licence like GPL - they're not compatible with Unreal's licence)

[tight schooner]

https://learn.unrealengine.com

[umbral merlin]

I appreciate your comment. It woud be awesome If theres any tutorial video or document about how to use speech recongnition library. We must rush if we change python from C or C++.

[icy dragon]

Integration depends on the library you'll end up using. Check the docs on what function to call, then call it from Unreal C++.
There's also Third Party plugin template when you're making a new plugin, it shows how to hook a third party lib.

[oak ember]

See i have the FPP melee animset ... i want to use it with alsv4 i know how to play anim montages in alsv4 and i am able to attack but ... i want the animations to function only the upperbody i want to know how to blend layers in alsv4..... any tuts??

[shadow sentinel]

Thank you!

[open latch]

Does anyone know why this doesn't work properly on built ? It does work as intended in the editor, but when packaged it doesn't function

[umbral merlin]

Thats a whole new part for me. I will have a try.
Many thanks

[jagged stone]

Given a location, a rotator and a distance. How can i calculate the ending location? This is what I came up with i think it works:

[dreamy yacht]

Hi, can somebody help me? I have followed this tutorial to make a simple outline for objects ( like here )

\

I want to start outline for A.I. cars when they are in certain range from player's camera, but as test object I chose the simple box static mesh\

( maked on the image in red circle )

*marked

The problem is: the game engine finds the box and shows the outcome with print string

but looks like the engine can't find the tagged test object

and no outline is visible

looks like the engine can't find the searched actor , although it has the tag

[marble tusk]

You're not inputting anything into the traced actor pin

[twilit lion]

Hi. What's the class name for getting Material Instance? I tried "Material Instance", "Material Instance Object Reference", "Instanced Material".. If I try "Material", I get all materials, except for the Material Instance ones.. Anybody know what to type as class name to get the Material Instance assets?
I can get all assets, and then filter out, but it'll take more time to get the array than if only materials.
EDIT: After getting all assets, then filter by name, I was able to retrieve the asset class name from the material instances that it found, and printed to a print string.
Short answer, "MaterialInstanceConstant" is the class name. 🙂

[dreamy yacht]

okay, looks like the searched, tagged actor is found

but still no outline is visible :/

damn, looks like there'is an internal error in material code

gimme 5minutes to fix

[dreamy yacht]

seems 2be workin' now

THANKS 🙂

[dreamy yacht]

another problem - the detection range is set for 250000 units, but the outline rendering range is very short ( like 20metres in front of outlined actor )

I mean the range, where the outline starts to show up is very short like 20m

[versed sun]

can you make outline thicker ?

[dreamy yacht]

that doesn't help

I have to make the outline visible range wider

for now it's like

and I want to force the engine to draw the outline sooner

and I don't know if it's related to LOD of the car or not

The wanted function is: when A.I. car moves away from player car ( player camera ) , the A.I. dissapears in dense fog ( disabled at the moment of testing ), then only the A.I.'s car outline is visible

do you know how to change the outline rendering range ?

do you think, that outline rendering range is stored inside the outline material itself ?

[dreamy yacht]

okay, I found it

[glass stump]

If I wanted to save the state variable from a BP into a save game obj, would I create a variable in the save game obj of the varaible type 'BP state variable' (directly referencing it) or would I create a new state variable, or maybe even a bool variable?

[maiden wadi]

Your state is nothing but a number of some kind. All you have to do is copy that number into the savegame object, and be able to read it from the savegame object.

[glass stump]

And then I can load it back when the level starts so it assigns the correct last states to each object and implements the appropriate conditions?

Hmmm, so I guess a integer would be best.

thank you!

[quick grove]

sorry guys, how can I check if an "Input Chord" variable is empty?

I mean... if key is set to none

[zenith trout]

get key name i think

[quick grove]

maybe "Get Input Chord Display Name"?

[zenith trout]

most likely

[quick grove]

ok thanks let me try

[zenith trout]

i dont remember the exact name

[ornate trail]

'fallback struct structure'? why would a create widget revert to this? Caused issues with my inventory and took a while to trace

[remote meteor]

refresh the node and recompile the bp

[ornate trail]

refreshing the node and reconnecting fixed yeah.. but more concerned as to why

[quick grove]

it works now!

[remote meteor]

blueprint struct sometimes are like that

especially when you modify an existing already being used struct

[ornate trail]

oi yoy, ok good to know. took forever to trace before I noticed some vars where getting passed as null

[jolly cairn]

hi all, i have this blueprint to move the players camera up close to the computer terminal i made. The position works fine but it's keeping the direction the same as what the player was facing

when all is said and done, i essentially want it to be like this

im not sure if it's the transform not working, or if im doing it on the wrong thing

this is what i want,this is what i get

[ornate trail]

zero out the rotator on the transform maybe?

[true folio]

ANyone wanna tell me why my object isnt rotating on pressing X?

[tawdry surge]

[lilac storm]

hey guys need your help , here is a screens of pivot exact same static mesh in Blueprint and on Level, why pivot is changing when i put bp into the scene? is this ue5 bug?

[undone surge]

is there a way to put a delay in an anim graph? like if i want to put a delay between these states?

[solar needle]

i have confusion

[keen pendant]

I'm losing my mind here. Anyone have experience working with the new Chaos System for Destructibles? My anchor field is constraining inside the box, and I can destroy elements close to the ground floor, but whenever there's any height involved, its just ignored and the projectile shoots through the walls.

[maiden wadi]

Not sure if you've solved this. But if you're moving the player's actual camera, then usually these are affected by ControlRotation. You would want to set that instead of the camera's rotation. However as another note for general design patterns I would advise not messing with the player's Camera at all and instead simply calling SetViewTargetWithBlend on this terminal actor. And then SetViewTargetwithBlend back to the character when done.

[lilac storm]

no ideas ?

[jolly cairn]

thanks i ended up cutting the mechanic but will be handy to know for future reference

[solar needle]

how to make spawned drone that follow the character. include the rotation. without using socket ?

[quick grove]

hi guys, I've just created an .html page where there's written only the current game version

how can I tell the game to go into that online page in background and check what's written using bp?

[solar needle]

nvm. how find look node actually work ? it just set mesh to look at the other mesh ? however it cuase the object. even in socketed mesh rotate whatever it wants

as long it find look at. i cant find constrain for it

i still didnt find how to anchor it

confused af

[gentle urchin]

If its attatched to a moving socket you need to apply the opposit delta rotation of the socket

**

[solar needle]

i repair my question

[gentle urchin]

I repaired my answer 😄

[solar needle]

i have my actor A set to look at other actor C with limitation of yaw only. so far so good. however, the actor attached to socket which is actor B. which is spaceship with all rotation. this cause the Actor A look at Actor C but didnt respec Actor B rotation like pitch and roll

which is pain in my head

despite being socketed

geez how the hell world of warship turret work like tht

[gentle urchin]

Wait, so you want actor A to follow actor B despite being set to view at actor C?

[maiden wadi]

Normally you would have a JSon or other structured container like that, that the webpage reads and displays. The game can access the JSon directly from a link as well. I don't know if BP has that functionality by default though. I doubt BP has the ability to parse HTML files though.

[solar needle]

i want Actor A to follow Pitch and Roll Actor B while it have yaw to see Actor C

[gentle urchin]

Follow ==> look at

Only set its yaw then

[solar needle]

yes. the problem that Actor A didnt like to follow the rotation of Actor B Pitch and Roll

[gentle urchin]

Read its pitch and roll

And set only yaw from the find llook at

[solar needle]

this cause the problem like i said

the turret (actor A) didnt have Yaw and Pitch follow Actor B

3 hour i cant find a clue

[gentle urchin]

Show some code

Easier :p

[solar needle]

i will show it

i feel 0 pitch and 0 roll need to fill with something

[maiden wadi]

The easiest method for turrets is usually to calculate and set Yaw and Pitch independently. The Base(Yaw) simply projects the target's location into it's own space and interpolates towards that on one axis and Pitch does the same. Applying clamped local space rotation clamps before setting the final rotation.

[gentle urchin]

You're not reading its current pitch and roll

[solar needle]

@maiden wadii follow this method

if it doesnt work i probably abandon project

[maiden wadi]

Part of the issue is you want to avoid Rinterp. You don't want a full rotator calculation. FInterp each axis independently.

The target point needs to be inverse transformed into the turret's local space. After that you can do easy assumptions like Zeroing Z out on the new local point to get a clean Yaw rotation. And it makes pitch easier as well. You remove the complexity of the ship altogether.

[solar needle]

what is F interp and R interp ?

[maiden wadi]

Interp means Interpolation. F means Float. R means Rotator

[gentle urchin]

You dont want interp tho

You want the other one

With something like const speed

Erh forgot its name 😂

[maiden wadi]

FInterpToConstant or something.

[gentle urchin]

Ahbyes. I mixed with lerp

[solar needle]

so Rinterp is changed to Finterp ?

ok

do i need to have socket ?

still causeing more bugs

what interpolation means ?

at this point i just need to know what is interpolation

[thin panther]

Blending between two things

[solar needle]

what blending ?

[maiden wadi]

You have a speed, and two points, and a current timeframe. With those numbers you can extrapolate a point between your two points given the time and speed.

[solar needle]

what is extrapolate ?

[thin panther]

Lets say yiu wanted to interpolate between 300 and 600, halfway through your timeframe you would be at 450

Extrapolate means to extract a piece of information iirc

Google could answer that one too

[maiden wadi]

"Extrapolation refers to estimating an unknown value based on extending a known sequence of values or facts. To extrapolate is to infer something not explicitly stated from existing information."

[solar needle]

so interpolate means information on middleground ?

[maiden wadi]

Interpolation - Estimating a value inside a set of data points.

[solar needle]

oh

it estimate between 2 point of data

[maiden wadi]

Correct. Your current rotation and your target rotation.

[solar needle]

yeah i have to redesign my project. again. it just that it cause unwanted bugs

[maiden wadi]

This small hiccup is causing an issue with your entire project? O.o

[solar needle]

changed to Finterpolate

the gun part didnt follow the main part

the R interpolate work fine

and the issue still unsolved

try to fix cause turret to jitter

i try to make turret follow the pitch and roll of the spaceship. it cuase the bug

[maiden wadi]

If RInterp works, and you're having jitter. Just set the rotation to the target rotation if it's within a margin. Should eliminate that.

[solar needle]

hm

lets try it

[maiden wadi]

When does the jitter show up?

[solar needle]

when it find the actual target

[maiden wadi]

Yeah. Just set it to the target rotation instead of interpolating then. It's causing it to over adjust.

There should be an easy nearly equal function you can use for detection of that.

[onyx violet]

so I'm making a system where in a 1st/3rd person game, turning with the mouse decelerates a player, I have a basic function setup to calculate it, there is a problem tho, changing FPS limit seems to make this equation more sensitive.

How can I factor in delta seconds from event tick to make this equation work the same regardless of FPS

[maiden wadi]

Usually it's just a simple multiplication. Not sure about your function, but most times you'll multiply a multiplier or a speed by Deltatime. So if you have a speed that does 800 units in 1 second. You multiply the 800 by Deltatime. This causes you with 13.33 at 60fps for example, meaning in straight linear you'd be able to move 13.33 units each frame for a total of 800 units in a full second at 13.33x60

It's probable you have a variable that dictates how much slowing to apply to reduce current speed. You probably need to multiply that by Delta before using it.

[onyx violet]

ok i'm gonna read this slowly to make sure I understand it but the way it works is the equation generations a multiplier number that's in range from 0.6 to 1.0, 1.0 just means you're not losing speed, while 0.6 you're going at 60% speed

[maiden wadi]

How are you setting the speed? Is this for lowering a max speed, or are you actively reducing current speed?

[onyx violet]

all i'm doing is taking the input axis value and multiplying it by this number that is outputted by the equation

[tiny meteor]

anyone know why this happens? I am spawning an actor and getting all child components, and it is returning 0

if it is placed in the world it returns non 0 value

[outer elbow]

Hi does anyone know how i can make this work in first person? Im following a tutorial on how to make a slide mechanic, but my project is a first person and their using an animation with a character, but I cant make a character because its first person and it would ruin it. Thats their blueprint with the animation (some nodes are cut off) And this is mine without the animation, how can i make the slide work without the animation?

[tiny meteor]

@onyx violet if you are applying a constant speed per frame then yes higher framerates will make objects move faster,

[outer elbow]

https://youtu.be/VfVu_KGKvAc

[tiny meteor]

you just multiply it by world delta

[onyx violet]

that's not what i'm doing...

it's not quite as simple as that

i have an equation that factors in mouse movement value and it's returning higher/lower depending on the players FPS

I guess I could just multiply that actually

i'll try messing around with that actually

[tiny meteor]

world delta is frame time, you just need to scale it by frame time

[maiden wadi]

Are you absolutely sure that this component's actor has any SceneComponents attached to the root?

[tiny meteor]

yes, I have the same actor placed in the world and it returns 3 child components

when its spawned, I can see the components in the editor view, it has components its just returning 0

[maiden wadi]

Really odd. All of that should definitely be valid at beginplay. :/

[tiny meteor]

yeah, idk why its nor working

could be cache issue

[barren sonnet]

Anyone know if there is a way to instance a blueprint on a spline instead of a mesh ?

[gentle urchin]

Sure, just spawn the bp actor along the spline

[normal dew]

sorry noob question, is there such a thing as a flip flop node but with 3 outputs? i want to have 2 inventory systems, pockets for small objects (batteries, meds etc) and large objects (fire axe, flashlight etc) can only go in the hands and can be swapped between hands or dropped

3 way flip flop node would be for swapping and dropping hand inventory items

[gentle urchin]

Just do a switch on int

Or switch on enum, if that could make sense in your system

[valid bolt]

anyone know how to move preview assets without moving the socket it is attached to?

[onyx violet]

I'm making a system in a 1st/3rd person game where turning with the mouse declerates the players, there is a problem where lower FPS is making the turn deceleration more sensitive, meaning they slow down more. The problem is that because they are getting less frames, the delta seconds is bigger, which makes multiplying by that makes the player slow down more, does anyone know how I can address something like this?

[flat raft]

Hey Hey! What asset type is this?

[unborn maple]

muzzle flash not spawning where muzzle is located it spawning underneath it

also tried get socket location

[flat raft]

unhook the rotation and see if the position is in the right place, first. Then you know if the rotation is off

[unborn maple]

yea it still underneath the socket

i added the muzzle socket as an extension to the barrel

so it might be because of that

[flat raft]

hmm.. it should still know where to put it. You muzzle asset might have an offset. Spawn a sphere or something instead of the muzzle and see if it's in the right place

[unborn maple]

will try that.

[ivory light]

does Download Image work with .jpg? i can't get either success or fail out of it

[unborn maple]

cube is spawning undermeath me too

[faint pasture]

Show your current math

[cobalt gulch]

How can I add post processes to a widget? I need this to only effect a part of the screen

[onyx violet]

this is what I have, I'm going to try using the character movement component and use the rotation rate

[faint pasture]

Either do it in the widget materiel or mask

[small shore]

using UE5 and AI perception hearing is giving off this stimulus location

[faint pasture]

Divide by delta seconds. But you really oughta precalculate a turn rate. Also functions are better without branching, just make it a pure function.

[flat raft]

add a socket to your hand to see if it spawns there correctly. Basically, start removing stuff to see where it works correctly, then procced forward slowly and see where it breaks. That's what i do.

[faint pasture]

MovementMultiplier = SomeFunction(TurnRate)

SomeFunction probably just being a map range clamped on TurnRate

[faint pasture]

MovementMultiplier = MapRangeClamped(AbsoluteValue(TurnRate))

[cedar sparrow]

Is there something that I can use to notify all blueprints on the board? Specifically, I have some units on the board and some of them regenerate health at the start of the "upkeep" phase of a new round. In my game mode, when I switch to the upkeep phase, how do I send out a message to all blueprints that "upkeep" has started and they should trigger whatever their upkeep events are. Or, do I have to do a "get all actors" and run that event if it exists?

[onyx violet]

what do you mean exactly by precalculate a turn rate? would using the character movement component rotation rate be a better alternative than this?

[faint pasture]

Depends on if you need turn rate for anything else but just calculate it earlier in the frame and then you have it

[faint pasture]

Dispatcher

Your game controller, wherever that is, can have a dispatcher to notify everyone what turn and phase it is

Everyone who cares binds to it on begin play

[cedar sparrow]

you mean like a player controller? or whatever class is "controlling" the game?

[onyx violet]

I apologize to keep asking questions I know it can be annoying but when you say calculate it earlier in the frame, what does that mean exactly?

[faint pasture]

Or you can just get all actors with interface

[faint pasture]

Yeah, and it shouldn't be playercontroller. Either gamemode or gamestate I'd guess

[cedar sparrow]

Ok thanks, ill start looking into dispatchers

appreciate it

[faint pasture]

For a turn based game this would be fine as you won't be doing it hundreds of times per tick

Interface would be simpler

[unborn maple]

just did attach emitter and made a scene component that work better then doing a bone

[gentle crest]

hey I had a quick question, do you guys think I should only use one player save bp for each person?

[faint pasture]

You mean for multiplayer, should there be 1 save file per player?

[gentle crest]

yea

[faint pasture]

Yeah I think that's a good idea for serverside saves, that's how Minecraft does it

1 save file per world and 1 per character

[gentle crest]

ok cool

thank you

[drowsy nexus]

multiple weapons

one that is fully automatic
one that charges up and explodes on impact
one that is semi automatic

i want to be able to switch between these weapons at will, they will have different models

is there any guides or things i can use as reference to do that?

[faint pasture]

Any super basic weapon tutorial would go over that but how far along are you right now? Do you have a weapon actor that is able to be equipped and fire?

[drowsy nexus]

i have a character who can switch between 3 guns (all identical just different colours and when i shoot text is displayed (3 different texts) but not shooting occurs )

[faint pasture]

Do you have 3 different gun actors or a gun actor with 3 different modes or is this all built into the Character with no gun actors at all?

[drowsy nexus]

there is an adult gun and 3 childs

[faint pasture]

Do you mean you have a Gun class and 3 subclasses of it?

[faint pasture]

K that's good

So you said you can already swap between the guns?

Make a StartFiring and StopFiring events in GunBase.

[drowsy nexus]

yeah with the mouse scroll wheel

[faint pasture]

In the child classes, implement the logic on StartFiring and StopFiring

[drowsy nexus]

i am just nor sure where to put the shooting code? do i put it on the individual guns

[faint pasture]

There's a million ways but yes for now, just have each gun fire in a different way

The base class just has the StartFiring and StopFiring events, so in your character it can be like

MouseButtonDown -> Get CurrentGun -> StartFiring
MouseButtonUp -> Get CurrentGun -> StopFiring

and they'll behave differently

[drowsy nexus]

so in the specific guns i would have

Gun 1: event start shooting---fire bullet

then for my fully automatic gun i would have the start stop

[faint pasture]

Then for your chargup you'd have a different bullet and you'd fire on StopFiring, passing some info to the bullet about charge

You could make a function in BaseGun called FireProjectile which takes a class for the projectile and does all the math on where to spawn it and what direction it shoots in etc.

But do it all seperately first

[drowsy nexus]

makes sense.
currently I have nothing but the shooting stuff just using the default gun and character models etc. once i have the 3 guns down should i then get all the scaling correct? maybe replace the preset gun models with some bad models i make

in prior projects i have had ammo stamina health etc sorted so they could be my next step

[drowsy nexus]

@faint pasture so i have this for my fully automatic gun but it is still semi automatic

[faint pasture]

FiredBullet /= FireBullet

[last briar]

guys i was trying to make a vaulting system from this tutorial but it isnt working and idk what to do

i dont really know what to do

bruh

[faint pasture]

Back up and do something smaller if you're lost.

[zealous moth]

@faint pasture terrible advice in fact you should add more features until it works

[tight schooner]

@last briar if you're serious about making that work, you need to debug it by

1. Understanding what every part of that node graph is supposed to do
2. Determining if every part is producing the output you expect by using breakpoints, print nodes, and debug shapes

If the tutorial didn't convey point #1, then it's a bad tutorial and you should instead learn BP generally until you can make your own vaulting system

[outer sandal]

Hi, can anybody explain to me, why does the node keep coming out like this

When the code is like this

Shouldn't return anything
And the input parameter... should be as an input, like honestly...

UFUNCTION(BlueprintCallable) ofc

[dawn gazelle]

Using an & on the variable type means it'll return a pointer, no?

[thin panther]

There isn't much point us trying to help when you have done little debugging past, "it doesn't work". It would be more helpful to understand where specifically it doesnt work, and if you dont understand even what the code does and it was blindly copy pasted, then you need to understand what you are doing before you can "fix" it

as seanny said

[outer sandal]

Well, technically it shouldn't return anything, but it should interact with the Input directly through reference/Pointer

So I'm just asking if the editor just handles it like that or if I'm doing something wrong

Ofc, I may be completely wrong

Basically trying to figure out the whole blueprint workaround

[dawn gazelle]

Putting the & on a variable type on a function parameter makes it return that variable, even if your return type is set void. You're basically declaring that variable to be of a pointer type, so if you set its value within the function, when the node is executed the output will be whatever its value was set to.

I think if you remove the & it'll behave as you expect.

[outer sandal]

Just thought if that would be the case, it would function in the blueprint just like a "set <variable>" would, aka that FGBAbilitySet_GrangetHandles being both input/output

[outer sandal]

I mean, Gonna try if it's gonna actually remove abilities wihtout the reference to it, you're right, should try everything

[dawn gazelle]

and failing removing the &, put a * in its place... I'm not super great with the syntax yet myself XD

[quiet shuttle]

Im wondering if there is a way to call functions or events on certain points of a music/audio track. I have a couple different actors that I want to light up in sync with the music they play. Would something like a sequencer be able to do this?

[outer sandal]

Works great without any reference or pointer... Alright, Blueprints just don't give a damn about anything and just doing direct referencing themselves

Anyway, thanks for the input, much appreciated

[tawdry surge]

You can do that with meta sounds in ue5, or by analyzing the sound file and saving the playback positions you want to fire events, either in a 3rd party software or manually

[iron bone]

Any ideas for why my character is teleporting to the "predicted location" instead of interpolating there? I've tried seemingly every combination of numbers in the two spots I circled

this is ue5 btw

[tight schooner]

Not sure. The InterpTo nodes are meant to be run on a ticked event though, i.e. on every frame

If you're only running it once, then you'll only see it move on that frame

It's interesting you're saving the start location to a variable though. Usually you see that in timeline-based movement where you directly interpolate between two locations...

If you have no idea what to do, try disconnecting that Set Actor Location node from the execution line, and reattach it to Event Tick (and enable actor tick in the class defaults panel)

Then you'll see it move around or something when you push the R key

[iron bone]

thank you seanny! Going to try this

[crimson saddle]

I have two small-ish questions:

1. What is the best way for an object to store a reference to a player in a multiplayer setting? (Potentially with Ai players) String id, direct reference to a pc, a reference to the playerstate, etc?
2. What is the best way to keep track of player resources or score in a multiplayer setting? (Also potentially with Ai) What object (on the server I assume) should be keeping track of all the players and their scores? (The first question kind of applies here too)

[crimson saddle]

Thought of a third question:
What's the best way to kind of simulate multiple owners to an object? I know it isn't possible to literally have multiple object owners, but I'm not sure how to best make a mechanic that acts that way. This is also kind of related to the first question because I assume I need an array or map of players in the object.

[faint pasture]

What specific mechanic are you thinking of?

[faint pasture]

PlayerState or Pawn for both.

Depends on your design

[crimson saddle]

If players could all "own" a stake in an object on the map. Essentially I think the object would just store all its owners in an array, but I'm not sure if that is the best way, and I don't know who the "real" owner would be in an underlying engine sense

[gentle urchin]

Would the real owner be important

I imagine not

[crimson saddle]

In a multiplayer setting it would just for calling events and functions on that object I think. Maybe I am thinking wrong though

[gentle urchin]

Is this a loot sharing mechanic?

[crimson saddle]

No it's more of like a plot of land sharing mechanic

[gentle urchin]

Yet you can have several owners?

Id hate to share my land with others 😅

[crimson saddle]

If a team owns something then multiple players could control the land

[gentle urchin]

Ah like that

[crimson saddle]

I just know that server calls don't work when called by a non-owner (I think)

[gentle urchin]

Id let some team entity own it i think

[crimson saddle]

Wouldn't my query still be applicable though? The entity has an singular owner technically right? How would I operate on it without actual ownership?

[gentle urchin]

True, it would

For access id just check if the player is part of the owning team i guess

[crimson saddle]

Would my server rpc calls still get through?

I was under the impression they always fail if not called by the owner

[crimson saddle]

Right so even a team entity needs to be owned by someone, if I wanted to operate on an object owned by the team I'm not sure what I would do

I guess I would have to start all server calls in the player pawn/controller and run that somehow through the team entity or just directly to my team-owned object

I'm not entirely sure

[gentle urchin]

I think the team entitiy would be owned by server, so only server can verify access to it ?

How one would go from there im not 100% sure about really

[crimson saddle]

I think anything that needs to be called on a team-owned object would need to start on a client so the server can do the rest

I suppose the team entity is really just holding an array of player states, and maybe a score or whatever

Feels a bit like a task that could be given to the game mode or game state

[gentle urchin]

Sounds reasonable

hi guys

my anim montage is not playing

its in character bp

i didnt changed any defaults in anim montage i created it and added it to character bp

can anyone help me with this?

[icy dragon]

Make sure your anim graph uses the slot the montage is using

[trim matrix]

i have this

and do i need to change defaultslot?

to attack ?

i cant see attack in slot names

[desert juniper]

in your anim blueprint

[trim matrix]

i added this

in that slot i want to change to attack? from defaultslot

right/

[desert juniper]

leave it on default

[trim matrix]

ok

still its not playing

anim montage also i need to leave as default?

[desert juniper]

yes

[trim matrix]

ya i set every thing to defaults

but its not playing

i added round one

rest is from ue5 default anim graph

[desert juniper]

should be fine 🤷‍♂️
is it that it's just not replicating?

Hey everyone! I'm making a character and trying to get it so that the skeletal mesh reacts to the world with physics (they don't phase through walls if outside collision) any ideas how I could do this? Thanks!

[wanton galleon]

Hi, don't really know where to ask that. My character is not affected when I set my Max Walk Speed, do you guys have any idea what could be happening ?

[quick grove]

did u connect it to "Character Movement"?

[wanton galleon]

Yeah :/ And even when I set it to 0 in the detail panel directly, it seems like it is not affecting the character... i'm using the simple move to location to move

[dreamy yacht]

I have problem, that sucks. A car mesh ( schoolbus ) with only base lod ( LOD 0 ) behaves in such way

When the camera changes then it looks fine

seems like LOD is the problem, but there is only base LOD ( LOD0 )!

wtf

the other car behaves in similar manner

[abstract mulch]

Hello! this is my first time posting and I hope this goes here?

I am trying to make an endless runner for my first game, but I dont want the player to run for ever I want the player to stay in place and make the ground and everything move past the player.

the problem is that eventoverlap fires twice. Always! It keeps spawning the tile twice. A ''do-once'' should do the trick but it doesn't fix the issue. I tried looking up online but people say delay is best way to fix it but I feel like I want to just make it work with out delays... If you need extra information I'm happy to provide.

Hi, does anyone have an idea how to set 1 camera in front of player on monitor 1 and another back camera of the player on 2nd monitor display?
Thank you any help in advance.

[quick grove]

guys do u know why the input selector key doesn't take the ALT and the CTRL keys?

[vapid grotto]

here result i need,
ignore ms paint my skills 😉

[spark robin]

Im rather confused here https://youtu.be/X0_Sm0kc95Y

Like I set the active pawn to be my "mainMenuManager", I iterate every tick to make sure that all camera components in my "mainMenuManager" except the correct one is inactive.

Ive done debug prints to make sure the correct actor owns the players viewport (so Im actually looking through the right actors camera, unfortunately it doesnt seem to be a way of ensuring you are looking through the right camera component other than disabling the other camera components of the actor)

Yet somehow, my view is located in a different location from the camera

The pattern is that the view location is offsetted by the location of the viewport when I start PIE. My first though was that the player controller must be doing something funny, so I double checked that its truly set to the default "PlayerController". Ive also made sure that y player pawn blueprint inherits from "Pawn" and not something else

Even stranger is that I can see the camera Im supposedly looking through - clearly being in a different location

[icy dragon]

You could setup a split screen viewport, but it might infringe a patent.

[vapid grotto]

hahhaha 😆

[crude fjord]

You can use nDisplay to handle multiple monitor setups like that

https://docs.unrealengine.com/4.26/en-US/WorkingWithMedia/nDisplay/

[vapid grotto]

thanks

[gentle urchin]

Why iterate every tick?

Sure theres an event for every time it should change

[glass stump]

Is there a step-by-step guide on saving and loading different types of variables in UE4? Like even stuff like saving the last state of each button, etc?

[crude fjord]

Is there a BP equivalent to the "Camera Position" material node? This works most of the time, but it does not always match with the currently rendering camera (for example when overriding the camera or when ejecting in the editor)

I would think it's quite common to want the current active camera position, but google seems to disagree as most people seem to use the above

[tawdry surge]

Well when you eject you're no longer possessing the player controller, pawn, or associated camera, so it makes sense it wouldn't work then.
If you change view targets or however you're switching cameras, it might not be updating the camera manager. Not sure why else it wouldn't work during regular runtime

[crude fjord]

It indeed makes sense, but I can't find another way to access the actual rendering camera

[gentle urchin]

https://docs.unrealengine.com/4.27/en-US/API/Runtime/Engine/Camera/APlayerCameraManager/

GetCameraViewpoint perhaps?

[trim matrix]

Does anyone know what does message means ? At first i thought it was an error but everything is working well

LogScript: Warning: Script Msg: Divide by zero: Divide_DoubleDouble
LogScript: Warning: Script call stack:
    W_Healthbar_C.ExecuteUbergraph_W_Healthbar
    W_Healthbar_C.OnHealthChanged
    PlayerController.ClientRestart

[crude fjord]

Wouldn't that have the same issue as you're still accessing the camera in the player camera manager and not necessarily the render camera?

Also that one doesn't seem to be blueprint exposed, if it has to be done in c++ so be it, but I'd prefer a BP only solution

[crude fjord]

The warning is pretty clear, isn't it? You're dividing by zero somewhere. The reason that it might still work is that it probably has some fallback value which it returns when dividing by zero and that fallback matches what you'd want to see, but it's better to fix the math itself

[trim matrix]

It's from the Lyra code i did not touch anything 😄

[gentle urchin]

Even if so, it should be fixed imo 😄

[gentle urchin]

Perhaps. Not at pc so cant verify , but i seem to recall having similar issues as you are experiencing, and found a bp only workaround

But cant recall what it was (nor which project)

[icy dragon]

Could nDisplay be used for game? I thought it was just for virtual production, mainly large chained screens

[hybrid herald]

I have a savegame that doesn't read when its in a packaged game? Any clues what is going on?

or rather..its just a MAP-variable (string to string) that is not being read

other data loads just fine

[crude fjord]

I haven't used it myself, but it's a runtime feature, so I don't see why not

[crude fjord]

That's a shame, but good to hear that it should be possible at least

[spark robin]

To be sure its using the right camera component

The fix I found was rather strange: If I set the gamemodes default pawn & player controller back to default (so the player controller & pawn is no longer the classes I created that I want to be the player controller & pawn) and then instead set them to the correct ones on begin play in the player controller & pawn itself - the issue went away

You get the idea that the game mode would spawn a duplicate pawn or something - but according to my print statements that isnt the case

So... I did something... it worked... and I still have no clue what the issue really was, feels like an engine bug

[next carbon]

Does anyone know how to work with physical controllers? I'm creating a second local player controller but it's not picking up my second gamepad

[icy dragon]

I think there is a setting for that in Project Settings

[next carbon]

Hmm - do you have an idea what the setting is? It's mostly just input mappings

[gentle urchin]

Right, but checking every tick sounds very excessive 😅

[wanton galleon]

Hi, it is possible to get in blueprint the number of UV channel of a mesh ?

[mossy falcon]

Since I just started to really get into unreal engine I got a little confusion to clean up
does each 'Material' only got their respectiv blueprint or can I for example place two door. I want to leave door 1 as is. But with door 2 I want to change something in the blueprint. Do those changes affect door 1 or does each entity of the door have the main blueprint from wich they inherit everything and I can make changes however I want for each instance of the door?

[mossy falcon]

thanks, one confusion around BP less

[light harbor]

Does anyone know how to do a checkout that adds total prices and subtract from wallet, I am trying to make a supermarket/ shopping game where I interact with groceries by pressing E which then goes to a cart then I go to the checkout till which will show the total price to purchase etc.

https://www.youtube.com/watch?v=GuRZfr8ZeWI the only one similar that I have found online

[icy dragon]

Go through array of items in cart, accumulate the total price, and deduct the wallet with the total price.

[mossy falcon]

set total to 0
for each ITEM in CART
total += get item price
wallet -= total

this would be a basic pseudo code for what u want

[light harbor]

ok thank you for the suggestions

[worn gyro]

I have an issue here, whenever this pitch passes 90, it will go in the opposite direction

so if i add for example, current relative pitch + 46, first time it goes 46 fine, next time when it hits 90 it will drop back ddown to 88, 46+46 = 92 so 90-2 = 88

WTF am I doing wrong here?

Having some issues with a timer based on when a switch is on. It should calculate the time passed from turning on and multiplying it by a given variable and setting total usage. But it always reads 0, anyone know where I've gone wrong?

[faint pasture]

To start with, have one timer variable and have some function to convert it to hours and minutes if needed.

Just use some float for seconds or whatever

[mental lake]

why stop watching tutorials lmfao

[gentle urchin]

They're often very lacking ^^

And some even teach you bad stuff

[faint pasture]

Because they suck and every damn day there's someone in here who's into some tutorial way beyond their understanding and asking for help

Hey guys, I'm trying to create a mini game like repairing generator on dead by daylight like here (https://youtu.be/zV4gwFsazMs). Only inputs here are exit and qte actions(space for example). But I don't want other inputs to be executed like jump for space. Creating a new pawn, and switch during the qte is the best to acheive that?

[faint pasture]

The concept of following along and painting by numbers is an awful way to learn. You won't REALLY get it until you branch out and do something on your own. By all means, tag along for a little while, but you're gimping yourself. Once you sort of understand how the engine works, just go for it and make something on your own.

[mental lake]

I prefer Udemy because I can contact the instructors directly and the response times are relatively faster

Though I've used this before

[icy dragon]

Gate the jump function when QTE session is active

[icy dragon]

Okay Udemy promotor

[mental lake]

I do not disagree

[gentle urchin]

If you found some good ones, thats all well and good :p

Their pricing sucks

And I'm getting good at UE even with free resources

you are supposed to gather the information from all the object that you would want to save, say by a delegate or objects submitting themselves to game mode or such

then you set those info into the SaveGame Object, then we can save it

[fast thistle]

I tried : smiling_face_with_tear:

Can I be helped or I’m I too far gone

😭

[remote meteor]

are the stamina values printing correctly?

[fast thistle]

By that you mean ? ( I apologise)

I very new to this

[remote meteor]

do a print string after you set stamina values

check whether if the values are correct in the first place

[fast thistle]

Yea I think so

[iron bone]

I used a timeline to replace the "get world delta seconds" on the Vinterpto node and now it's acting like I want it to- Thanks again!

[remote meteor]

if you sure values are correct, then check your progressbar widget value binding, if its set to the correct function

[fast thistle]

This seems to be find remember my progress bar for stamina is not responding

Well I don’t think so 🥲

[remote meteor]

this one 🙃

[fast thistle]

That is the one

That’s in there

i cant change the value , is that right?

[remote meteor]

yeah if you selected the binding you cant change it

then do a print string within the GetPercent2() function and see what values it is getting or whether if its running or not

[fast thistle]

It works

I think I did something wrong 😑

[slim grove]

how can i loop through an array that starts with nothing in it

[hushed cobalt]

I'd say do a null check for the contents, and don't loop until there's something in it

[remote meteor]

drag the Stamina value into the String variable in the Print String Node

😅

[slim grove]

well i need to do whats in the loop to get stuff in it

[hushed cobalt]

What I mean is don't attempt to access or iterate through the array until it has at least one child. So you'll need to do a null check somewhere

[slim grove]

also how can i replace an element in it

[fast thistle]

🥲

[hushed cobalt]

reassign the index you're needing to replace to the new value

[slim grove]

wdym reassign

like whats the function

[remote meteor]

set array element

[iron bone]

Any suggestions for adding a second of floaty-ness to a character after being put into the air? Similar to how the jump makes you not immediately fall but I don't want to launch the character

[fast thistle]

The end result of that will be numbers right 🥲

( apologies)

[remote meteor]

yeah, we want to see the actual numbers that is being set

[fast thistle]

Yes Sir working and decreasing

[hushed cobalt]

I'm trying to get an actor to rotate to point at the location the mouse clicks on. This is just setting the actor to look in one direction. I also noticed that when I get the world coordinates of the mouse, it's way off compared to the location of the actor, even if I click on the actor.

Does someone have a way to get the actor to rotate to the x,y position of a mouse click based on the terrain?

[remote meteor]

gravity scale in the character movement

[fast thistle]

The numbers are working like the bar should be 🥲

[hushed cobalt]

I also tried using get hit result, but unsure how to use that tbh

[remote meteor]

you need to to a line trace from these values

[ornate dragon]

Hi. What would be the proper way to disable game input when mouse is over the widget and it's child elements, while still allowing game input to work outside the widget?
Example: When mouse is in the inventory window, clicking on item icon or inventory background performs actions with character.

[remote meteor]

actually never mind

[remote meteor]

use Hit Result Under Cursor in the player controller

[hushed cobalt]

So I was looking at that, but I'm not sure how to use these. I cant seem to get a location from result

Any advice

[fast thistle]

So the numbers increasing , decreasing, refilling , but the bar is solid grey

[remote meteor]

use by Channel, Visibility, break the hit result, get location

[remote meteor]

just for a sanity check, can you drag in a new progress bar and do the binding again and check the result?

[fast thistle]

Ok

[hushed cobalt]

you're a beautiful soul ❤️ If you don't mind, what exactly does "Break Hit Result" do? I'm new to the Unreal engine, but "break" has always meant breaking a loop, so this is a new context for me

[fast thistle]

It worked

You a. Genius

Thank you so much

[remote meteor]

when you see blue node, it usually means its a structure, structure can contains other variables.

breaking a struct in blueprint means a node that allows you to see all the variable in the struct at once

while making a struct in blueprint means you can make up a struct with a set of values

its like a container

[hushed cobalt]

Oh ok, I think I get it. So "break" in this context just means breaking the variables out of their structure?

That's sick. I appreciate it

[remote meteor]

🎉

[remote meteor]

if setting input mode game/ui doesnt fulfill then it can be quite hard to separate the inputs since they are both independent from each other

[glass stump]

If I have multiple doors in a level that are opened only when all of the associated switches with the door are 'On', how would I be able to save this in my SaveGame Object so it will load with the right switches set to on as when the player last left the game, plus whether the door was open or not?

I know I have to save the variable(s)in the object but how exactly and how do I reimplement it on load?

[remote meteor]

on load, you tell the doors here is you current state and update them accordingly

[slim grove]

how can i loop over an array of a struct and see if one of the struct's value matches another value

[remote meteor]

equals one by one, or you can make a array, add unique both struct, compare if return index from the add unique is -1

[glass stump]

when you say update them, does that mean calling the events that would correspond to each variable being on?

[slim grove]

i dont understand?

[remote meteor]

you probably have something similar in your savegame TMap<FName,EState>

on load, you can get all your doors, check if they have an already saved state in the save game, if exists, set them accordingly

[glass stump]

Ah, I see thank you I'll try it out. :)

[remote meteor]

whichever way you prefer, former is easier to make but not efficient and require exactly the same values, latter has more control

[slim grove]

the thing is i care only about one value and the input is an array aswell i cant execute the rest of the loop until a result is found

[remote meteor]

so we are finding duplicate "unique key" in an array?

[slim grove]

yeah i cant use a map because it needs to be replicated

[remote meteor]

i guess?

[slim grove]

wait no i dont need a dupe i need to see is any value matches another value and return the index its found at and if its found
ex:
array [["e", 1],["d", 4],["yeet", 9]]
and im looking for "e"
return: true, 0

im sorry

[remote meteor]

e matched with one of the e in yeet?

[hushed cobalt]

Back again, after using the get hit, which mostly works, it seems to be off a few degrees when looking anywhere aside from true north or south. Screen shot for example, I was clicking directly on my enemy

Is there some padding I may be missing? Or is this just a limitation of the "Look at" function and I should write my own..?

[remote meteor]

ahhh its time to maff

[hushed cobalt]

lmao so write my own, got it

[slim grove]

no i mean [[struct][struct][struct]]

and i need to check if one of the values in a struct is equal to an input and return the index its found at

[remote meteor]

because of the height difference

[remote meteor]

oh lol thats easy

[hushed cobalt]

I'll try compensating in my XY function. Thank ya

[slim grove]

thanks! that should work

also how can i make a function that can be used by any BP

without a cast

[remote meteor]

a function library

but minimum needs actors to access it

[gentle urchin]

Some rules to it, but you'll figure them out

Like you cant reference something from inside a bp etc

Must be an input to the function

[dim tapir]

This might be a more accurate channel for my question.

"Hi, new to coding and working on my first game. I'm trying to make my character take damage but I can't get it to work. It does the "damage applied" print but not the remaining health..
First image: Enemy BP
Second image: Character BP"

[gentle urchin]

Damaged actor

Is not connected

[dim tapir]

Umm, not sure how to call on my player for the damaged actor. I set a tag on him "Player" but my "has tag" doesn't go in that box

[faint pasture]

Loop over the array of structs and see if one of the structs values matches another value

[dim tapir]

Sorry complete beginner.. what?

[faint pasture]

How does your attack determine which actor it hits?

[dim tapir]

By using the damaged actor I believe

[gentle urchin]

Are you sweeping for hits?

Overlapping? Tracing?

Range checking ?

[dim tapir]

I would like it to be on overlapping

[manic geode]

Guys, can you help? Im trying to make a building system but these pieces (the transparent ones) are not interactable and I dont know hot to fix them. They were interactable when they had collision with the character, but when I switched that off - they became just fog

Damaged actor is the actor you're damaging. You choose that. Line trace, overlap, random actor in the world, self, however you want to do it.

Hi! I am trying to create a blueprint that will automatically create a material layer instance for the texture sets I import into the engine (Editor only). It seems that material layer instances are not exposed to blueprint? I can't seem to find a way to do it.

i am trying to make it so i take damage over time

like standing inside fire for example but when i walk into the zone nothing happens

Set a function or event by timer and use that to damage the character while overlapping

guys where can i learn BP thoroughly ?

i couldnt find any good channels on yt

[oak ember]

try official unreal engine youtube channel or read unreal documentations about blueprints

[flat bison]

i did that already

no luck

[oak ember]

documentations ?

[flat bison]

most of them arent written yet

[oak ember]

a channel named "astrum Sensie" his ARPG series helped me making a ARPG game and i got to learn a lot from that series

try that

[flat bison]

i'll check, thanks

[crimson saddle]

Does anyone have a workaround for trying to use map variables in multiplayer? I have just come to the sad realization that replication on them is not supported, for whatever reason...

[smoky rivet]

do for loops automatically detect whether the index should increase or decrease?

[thin panther]

Leanr the general programming principles rather than a hyperspecific tutorial series, from htere you can use MathewW's YT channel as a resource for various nodes
With a bit of knowledge in progammatic thinking, debugging, vector math, and built in functions, you should be able to break down your own problems into a solution

You wont find a compendium "learn bp thoroughly" course, because it differs for your need, and a lot of it is just knowing how to break a problem into a set of logical steps

[faint pasture]

I think so, try it

Just make a for loop from 10 to 0 and print the index. Remember the first thing printed is on the bottom

[tawdry surge]

I think for loop goes forward and reverse for loop goes backwards

Don't think it detects which way you're trying to move

[faint pasture]

You're talking about a raw for loop and not a foreach right?

[thin panther]

they should really have called the nodes
"for loop" and "pool rof"

[digital palm]

Hey, I changed the default character camera inside the lobby to have like in other games lobby. What should I pass to New View Target to the new Set View Target with Blend? How can I set the default character camera?

[faint pasture]

One question at a time.
The Set View Target with Blend, is that for setting the view target to the LOBBY camera or the gameplay camera?

What are you trying to do here.

[runic nest]

Does anyone know if it is possible to pause the custom rotator node in a material?

[faint pasture]

Does it have a speed parameter?

[runic nest]

Yes I have included a speed parameter but when setting it to 0 to stop the rotation the image is reset back to the original rotation (I was hoping for the image just pausing at whatever angle it happened to be at when the speed is set to 0).

[digital palm]

well ok. Basically the lobby is inside the same map as the gameplay. So What I'm trying to do first is to set the lobby camera in the begenning when the player enter the map. Then (where I said OnGameBegin) I want the default pawn camera, when players are teleported to the player start for game (not player start lobby).
So I tried to set the first view target with blend inside the level blueprint, because this bp is load for each client. I have another view target with blend inside my game, but idk what to put inside new view target.

Is that more clear x)

[faint pasture]

Maybe consider making a lobby pawn, which is your default

You log in and have the lobby pawn with the lobby camera

You choose your character

then you update the player pawn class and call restart player

To preview characters, you can spawn them locally

So effectively, at game start with multiple players, they all have an invisible pawn with just a camera at the same location and are all looking at different characters locally on their own machines

once they choose one, you set the pawn class for the controller and restart them. You'll need to adjust some of your functions in GameMode but it should be pretty slick and robust

[digital palm]

ok I'll try this. So posses the lobby pawn? When the game start, switch to character pawn right?

[faint pasture]

Depends on what you mean by the game starting, if that's using the gamemode's start event or your own

[digital palm]

yea a function to teleport players where I want, give them input mode game...

[faint pasture]

Look into the choose start spot and choose pawn for player and restart player functions in Gamemode, you can override a lot of them

[fast thistle]

Does creating a lote of widgets slow down performance

[digital palm]

looking good. Another point. In fortnite or pubg for example, in the lobby, the player always see his character in front of the other players. How to acheive this? because for now I only have player starts, and removing one when another player join

[sharp sigil]

Hi, I have a teleport ability which teleports the player (duh), but I'd like to move the camera smoothly between the two points. Any way to do this

[digital palm]

if the camera is attached to the player, I would say no. So maybe try to teleport the player smoothly

[sharp sigil]

If you mean interpolating the position between the two points, I was trying to avoid that due to potential issues (having to disable collision, networking problems possibly) but I'll look into it

[olive orchid]

Hey all, maybe someone here can help me out with a quick audio(?) blueprinting dilemma
I'm setting up a system that uses raycasts to determine the size of the space the player is in to adjust reverb settings. So far I'm just trying to find the average distance of the past 16(can change, just what I have it at right now) casts, each hit stored in an array.

I have a function made up to calculate the average array, which is the Float Array Average node. The issue I'm having is that the average value keeps rising, and never stabilizes.

Here's what I've got so far: (edited)

[faint pasture]

@olive orchidYou sure you need an array?

Each tick, can't you just do

Average = 15/16 * Average + 1/16 * Current

Or just filter it with a slow FInterpTo

That'll average it for you and is easily tunable

[olive orchid]

I was considering the possibility of just doing it with something like slow FInterpTo (I'm planning on passing the values into middleware) without the array
I think I'm mostly concerned about the accuracy in that case, though

[icy mason]

Hey, I have a pretty stupid problem, my cameras don't work when I get in the car, instead it puts me in the ground
Any idea ? I really can't find any solution

[zealous moth]

it's your controller, you are using the controller's transform at the root

[dusty coral]

Hello guys how can i do battle royale zone with different closing point? Like "first zone closing to bla bla bla location." tahnk you

[faint pasture]

If you're concerned about accuracy I wouldn't just be averaging 16 random traces

That won't be very accurate and also will be distributed weirdly.

[dusty coral]

i want to make zone closing like that with random points

[faint pasture]

Show what "get in the car" entails

[icy mason]

its pretty basic

BP_PlayerCharacter

[faint pasture]

@icy masonDoes it work fine if you just spawn it on the map and possess it?

Which camera is it looking out by default?

[icy mason]

The one of my character, But when i enter in the car, None of the cameras are set up to be on the floor, and the character is deleted so is not his cam (If we follow the logic)

[faint pasture]

Are you sure? Are you sure you're not looking through the 3rd person cam and collision is screwed up? What happens if you just possess the car on its own?

Also your logic for handling possession and deletion is wacky, that could be part of the problem. You should do that through the PlayerController or GameMode

[icy mason]

I'm watching this tomorrow, I'm working so I get up in literally 4 hours 💀

I will try to fix the problem myself, I don't want to disturb more with my problems

I gonna recode all logics possession and deletion in Playercontroller or game mode like you said
Thank you for your help, I appreciate it

Hello just curious, I am working on creating a parking lot where AI vehicle can park. Now, the lot will be "upgradeable" so is there a way to create a spline path for the vehicle to follow based on any open parking spots using a socket on the mesh?

[trim matrix]

Is it possible to have an array of maps?

Im trying to store multiple maps. Each NPC has a map for their morph targets and corresponding morph t values

store every NPC's facial keys on a save game

[icy dragon]

I think it might be better to just have a vehicle AI that isn't based on spline, just go to point B

[faint pasture]

Why are they sets?

[astral stratus]

@faint pasture followed a tutorial learning how it all works

[trim matrix]

So I can get their names and values

theres multiple/several morph targets per npc

[lavish tusk]

hey! I'm looking for some help with the projectile movement component. I want my actor to shoot out when triggered, and put back in place when a button is pressed. I'm having trouble activating the projectile movement component twice, though. I'll trigger it, and it'll fire off, but then when I reset its position and stop its movement, I can't activate it again. does the projectile movement component only fire once per instance?

[faint pasture]

Have you tried resetcomponent?

[faint pasture]

K so start by thinking about how you want the 2 main functions to work

1. Where and at what orientation are you trying to place the object
2. Can it go there?

[lavish tusk]

I don't see that node

[faint pasture]

Drag a pin off the component and see what's available to you. Should be something like reset

[lavish tusk]

I see reset interpolation for the projectile movement component, but it appears to do nothing

[faint pasture]

In your case, right now, your "can it go there" test is whether or not that box trace hits ANYTHING. If that's not the desired behavior, change it.

[astral stratus]

@faint pasture well it all works if i unhook the entire box trace. im trying to learn how to make it ignore the ground so it will allow it to build on the ground

[faint pasture]

SetActive is what you want maybe

[faint pasture]

You don't TOTALLY want to ignore the ground tho right? You want it to embed in the ground, not go right through it as if it wasn't there, right?

[astral stratus]

correct

and it all works until i hook up the whole box trace

[lavish tusk]

yeah, I thought so too. but if I deactivate it and activate it again, it's unable to be triggered for a 2nd time

[prisma stag]

Since this does seem a bit simpler, do you happen to know of a way to make the turning smoother since it will be based on just going from point A, to point B instead of a smooth spline curve?

[faint pasture]

You probably want 2 traces (if you want to keep the box trace). One box trace for intersections with other things, and a sphere trace for placement against the ground etc.

[faint pasture]

It all depends on your context. The simplest approach to making something smoothly move from where it is to where and what orientation you want it to be is to use a spline

[astral stratus]

@faint pasture I will look into that

[trim matrix]

^

[faint pasture]

Maybe in a structure

Or rather, using structures

but that smells

[icy dragon]

Angular acceleration and PID perhaps?

[trim matrix]

You can add arrays to structure through BP?

[faint pasture]

You can have an array of structs with a map inside them. I think

[trim matrix]

no you cant create structures through BPs

[faint pasture]

Your savegame can be a struct full of structs with your map in them

You're telling me you can't create a struct in BP?

[thin panther]

Yes you can

Not ideal

You can make one in c++ and expose it to bp as well

[faint pasture]

Also this could just be an array of structs

[trim matrix]

what? how do i create multiple structures from bp then save them all into my save structure?

[faint pasture]

Your save struct can have members which are structs or arrays of structs

[manic knot]

Im trying to use the HUD class. This doesnt add the widget and the variables remain invalid. Am I doing it wrong?

[trim matrix]

how do i set a member to be 'array of structs'?

[faint pasture]

SaveGame
-NPCDataArray
--BobData
---Shapekeys
--AliceData
---ShapeKeys

Although why the hell are you saving this stuff in a savegame, does it change at runtime?

You'd think your saved NPC data would be stuff like location and inventory etc

[trim matrix]

huh? i have none of what your listing

[faint pasture]

I was sketching out what your savegame could look like

[trim matrix]

how do i set a variable to be 'array of structs'

its to save the faces/appearance of npcs

so u dont lose it when u reload the save

Like im not sure what to put in membervar 20

[manic knot]

Nevermind I just needed a delay, or rather will need to wait until HUD is initialized

[trim matrix]

to get an array of structs

[thin panther]

your struct

then change the type to be an array

[trim matrix]

ohhh okay thank you so much

[ember mortar]

Hey guys, how do you change rich text block styles in runtime? Any ideas?

[tawdry surge]

Its probably a property of a struct on the text block. You'll have to make one with the settings you want and set it to be the one the block is using

[ember mortar]

Well it is as easy as I thought it should be. But I was getting the "accessed none" error while reading the variable which made no sense so I started looking for another solution.

Then I restarted the engine and it for some reason started working. Weird. Thanks for the help though

[raven pilot]

seeking help

lets say my character uses a melee ability on another character, and then i want the receiver of my attack to play a certain animation, how would i do that?

(but i dont want the enemy to play an animation every time i hit them, only with that certain attack)

[prisma stag]

Sorry to bother, but do you happen to know of some video or explanation of these methods for vehicular movement?

[icy dragon]

TBH I just know it from Rocket League bot engineering xD

[prisma stag]

LOL. Well at least I know it can be used 😂

[trim pollen]

Seems like there are two steps. 1. Play character animation when some thing happens, e.g. a button press. 2. Check if character received a hit, and if so, what type.

If you can do both of these then should be pretty straightforward

[raven pilot]

haha yea am struggling with second step

[trim pollen]

We need to see how you have designed things to help

[raven pilot]

yes ur right

[raven pilot]

here is step 1

[trim pollen]

I can't read that

Super low res

[raven pilot]

k

[raven pilot]

is this clearer

[trim pollen]

Ya

[raven pilot]

k

[spark steppe]

that's still awful low res...

[raven pilot]

(ignore the ability rotation)

[raven pilot]

how do i make better

am using snip it

[spark steppe]

don't zoom out that much

[raven pilot]

i try to zoom in as much without cutting out code

[spark steppe]

well, if you hide/resize the panels on the right, you would be able to zoom in further...

but now it's at least readable

[raven pilot]

hows this

[spark steppe]

perfect

if it was cropped 😛

[raven pilot]

lol

[spark steppe]

but now it's good readable, so 9/10

[raven pilot]

[spark steppe]

go for that in the future and it's more likely that someone will look at your "code"

[raven pilot]

indeed, note taken

[spark steppe]

because its highly annoying if you have to guess what is what

[raven pilot]

yea i can see that

[trim pollen]

Also not entirely sure how this snippet relates to your question
