blueprint

[fast finch]

they are hidden in BP

[mental trellis]

Then good luck.

Unless...

[lunar sleet]

Are they?

[mental trellis]

Is the thing you're looking at always roughly at the same height as you?

If you don't have to think about gimbal locks, you're fine.

[fast finch]

at least it wont move for now

[mental trellis]

That isn't what I asked.

[fast finch]

i know to make the camera focus on a thing

just i want some freedom of movement while that happens

[mental trellis]

Something can not move and still be directly above you or below you. Or you can change position.

[fast finch]

ok you played skyrim or ciberpoon?

[mental trellis]

How is that relevant to the question?

[fast finch]

basicly when you talk to people the camera is locked into direction

but it has a burn area

so you can still look around

a person could be standing anywhere

above

below

right left

i need a solution for ALL those

[mental trellis]

Then quats it is.

[fast finch]

mh i am confused

i dont know what todo

[viscid viper]

hello im trying to get the mouse position on the world so i can move units there in a rts im building but for some reason the function it never return a value of where the mouse is when it was pressed
anyone know why ?

[barren dove]

do a debug sphere trace so you can see where it is and that should help you narrow it down

wild assumption is maybe something under the mouse is set to not block visibility traces

[remote meteor]

probably because the node hasnt executed as the SetLocation is on breakpoint

do a print afterwards and see

[pulsar vigil]

@remote meteor @lunar sleet https://forums.unrealengine.com/t/cast-simple-question/1373675/25 i explained more the thing and he found a suitable solution if u are curious for the exact thing i wanted to do

[lunar sleet]

So basically precisely what you were told to here

[mental trellis]

L2quats basically

[viscid viper]

print string print the exact same thing

[pulsar vigil]

Lmao sry for that if its the case i didn't understand exactly what u said then

[lunar sleet]

It’s ok, there’s more than one way to pet that cat, so we gave you several solutions, might have made it confusing

[pulsar vigil]

I mean i get what u said but i need several petting process with more delicate attention i may be slow lol (u can see my profile picture to understand it) (thats was my pfp before this)

[viscid viper]

the mouse is hitting the default map

[lunar sleet]

Maybe a mouse capture issue, altho if the debug spheres are showing , then not that

[lunar sleet]

Turn off trace complex

And also show where this event is being called

[orchid sierra]

Hey I have a question, let’s say I have a data table with lot of data such as textures etc. Let’s say now I am trying to get a row from that data table, I know that get data table row is getting a hard reference from this and it will cause hitch, or it will be loaded before nvm. I have made the type to soft reference. So theoretically when I find a row I will use async load. But the question is , if I am using before the node get data table row am I loading the whole table?

[lunar sleet]

Afaik yes

[remote meteor]

once you reference the data table, all the rows will be loaded

[lunar sleet]

DTs get loaded all at once

[orchid sierra]

Hm

[remote meteor]

so you are correct to move heavy assets like textures to soft reference

[orchid sierra]

Is there any better solution for this? Maybe data asset?

But still it will be loaded

Right?

[remote meteor]

soft reference only loads when you try to load it

[viscid viper]

i dont see the debug sphere and this is the where the event is called

[orchid sierra]

Or due to I made the heavy assets to soft reference it will be ok

[remote meteor]

when the data table loads, it knows it is a soft reference, so it doesnt actually load the texture

[orchid sierra]

Ahhh nice thanks for the info

[versed sun]

Sphere is too thin(0.0)

[orchid sierra]

I thought it will still load everything even if they are soft reference

[frosty heron]

it will load the soft reference (path to the asssets)

[orchid sierra]

Ok that’s good I guess

[lunar sleet]

Just a reminder there are also Data Assets

[viscid viper]

ok the sphere is in 0,0,0 not where my mouse is

[frosty heron]

your texture will only load and get hard referenced when you do async load

[lunar sleet]

So you’re not tracing to the map then

[orchid sierra]

I know but I guess due to I don’t have only textures but also animations etc I guess that data tables are better

[versed sun]

if you didnt Hit anything with Get Hit Results under Cursor, it will default to 0,0,0

[remote meteor]

you have to be thoughtful whether to actually needing to softload stuff

[orchid sierra]

Yes I know

[remote meteor]

texture is so far a must, mesh in second

animation i havent tried

[gentle urchin]

I tried softloading all my dialogue

Painfull to say the least

[orchid sierra]

I am using soft also for the animations due to they are almost 10gb of disk size and also I will not use all of them

[viscid viper]

but i clicked the mouse on the default map so why it says i didnt hit anything?
the map setting remains the same

[remote meteor]

10gb of animation..?

[orchid sierra]

Yes 😕

[remote meteor]

https://tenor.com/view/sweating-gif-7424342

[gentle urchin]

Theres anim compression methods avaliable 😅

Even a free plugin iirc ?

[viscid viper]

is there is something i can do instead of using the get hit result?

[orchid sierra]

Actually it’s 8gb but there are a lot

[lunar sleet]

Nothing that’s much better than that. I’d wager you have something wrong with mouse capture, maybe UI is consuming the input

[versed sun]

try turning Trace Complex off
Also, print the Bool return from the get hit result

[viscid viper]

the thing is i dont have ui ( the blue ring is a decal ) this is where i hit the mouse ( in the black circle)

[viscid viper]

the bool is false and i turn off the trace complex

[vernal snow]

Howdy all, so i'm giving a go on a visibility system - basically splinter cell's light meter where depending on how well light the area the player is in, the easier you are to detect.

So far i got what i think could mimic that with my current knowledge is:
a visibility Player float variable clamped to 0 and 1 with 0 being Hidden, 1 being easily visible
On the Light, a Collision sphere that are the same radius as the light (E.G Point Light's 1000 Radius unit) that upon the player entering will start a line trace every 0.2 Time to check if the player is visible from the light Origin.
If not, for ease of it the player isnt visible.
If its true, get the distance from the light to the player -1 with it and thats the visibility float variable after it goes through an Event that the player is referencing.
So far this seems to do what i want.

But i was wondering if there was something more under the hud or something that could make it easier to work with - Or any input on the matter.
I was suspecting to involve intensity in it but wasnt too sure - or something to do with that Attenuation radius value.

Or if thats could be under a different area, any input would be appreicated.

[lunar sleet]

Why can’t we see the cursor?

[viscid viper]

i think it cuz of the print screen

[tight pollen]

someone help, I have no idea how to change the size from the center using 1 float variable, when I move the right or left corner of the box, it changes the values ​​for Position X and Size X

[gentle urchin]

Is it hard to work with?

Multiple light sources can become problematic i guess

[undone temple]

For future reference, I solved this issue by disabling "Use distance-scaled camera speed" in the editor settings.

The issue is that Set Level Viewport Camera Info sets the viewport camera focus to the same position as the viewport camera. This makes the distance between camera and target 0, and if you're using distance scaled camera speed, your camera movement speed will then be multiplied by 0

[viscid viper]

i dont understand what the problem can be , i didnt touch the the level setting or have ui so why its not knowing where the cursor hit

[vernal snow]

The sphere collision makes sure to only "work" with the one the player is within said collision area.

I intend to work on it further so multiple lights won't conflict with it

[gentle urchin]

Multiple lights should contribute

With this method theres no bounce light tho

[vernal snow]

That's what I initially wanted but found it difficult and thought to work slowly on it to try and understand how it could work, so did a more simple approach.

I'm unsure how to do bouncing light or a form of ambient light.
Hence me coming around trying to see if others had input that might lead to a path to work on that'll achieve a ideal outcome.

[trim matrix]

what's the difference between invalidate & clear and invalidate timer by handle nodes?

[viscid viper]

does anyone know what i should do?

[lunar sleet]

Do you have any node like set input to game only or game mode and UI in your code anywhere ?

[lunar sleet]

The first one lets you return the handle, so it doesn’t completely get rid of it

[viscid viper]

yes to game mode and ui i believe

[lunar sleet]

Show that code

[viscid viper]

its in the player controller

[lunar sleet]

Add a set show mouse cursor in between those 2 and check it on

[viscid viper]

nope still the same

[trim matrix]

so if i had a non-looping timer in the code, i'd probably wanna use the clear and invalidate, right?

[lunar sleet]

Not really necessary for Non looping, I think

It only runs once

[trim matrix]

but i need it to stop while it's running

[lunar sleet]

Ah then yes

Tho idk how that would occur, like before it fired maybe?

[lunar sleet]

I’m not sure what’s going on there. Try setting input to game mode only for now.

[trim matrix]

if i have my timer setup like this, do i use the Time or Initial Start Delay to declare its duration?

[lunar sleet]

Time usually does it

[trim matrix]

cant test that now, as the code does some file operations

[gentle urchin]

Question is if you really need it

Or if its good enough without

[vernal snow]

From what im thinking - as its more so a proof of concept than a long term project - it would be neat to have and showcase.

I have two methods for it so im not too bothered if i cant, a rather simple and easy line trace - and the one with distance involved.
Just wanted to try and make it feel better i suppose

[gentle urchin]

Theres a plugin that does it like thief does it, if thats to your liking

Something something octahedron something pixel light sampling something

https://github.com/MatthewZelriche/UE4-Light-Detector

[vernal snow]

oh i see, i presume thats the name of the plugin?
I think Thief is similar to splinter cell so should be to the liking
Regardless thanks for the input on that matter

[gentle urchin]

Ah, nvm wasnt even a plugin. But an example non the less

[rugged wigeon]

I'm trying to implement some driving movement (not realistic) such that objects are generally moving forward at a high with some influence on the left/right and forward back movement to a small degree.

I'm trying to do this with floating pawn movement.

I'm really yearning to just set the velocities, but am finding that I need to do this goofy process of determining the desired velocity, scaling it to the maximum possible speed as a value between 0 and 1; applying that fraction to some normalized vector of the desired velocity, and then relying on the max speed of the movement component being set correctly to make this work.

Is there a less dumb idea here?

[lunar sleet]

Vehicle movement component ?

[tulip patio]

Guyz. Anyone know how to add collision on a skeleton mesh like we add on static mesh.

[lunar sleet]

I believe you need to use the physics asset

[versed sun]

Have your normal movement , and have a separate Scene that holds your Meshes
the Scene Hovers and moves around on the main actor

[rugged wigeon]

i messed around with that and concluded it won't work. I'm looking to do multiplayer and have curved tracks which introduces a lot oddities

although I think I was just being dumb about setting velocity

is there any downside to directly setting velocity on floating movement components? replication issues? anything?

[rugged robin]

Phys asset or primitive collision. other too difficult

[random pulsar]

hey guys ,when i move to another scene my character should be destroied and there will be an gameover ui ,but the character is in the scene and the ui from the player also is there but shouldnt be

[dawn gazelle]

Check your World Settings on the game over level. The game mode you're using may be wrong or you have defined classes you don't intend to use.

[random pulsar]

and that whould i do with this ones?

[dawn gazelle]

That's what it is set to on your game over level?

[random pulsar]

absolutely

[dawn gazelle]

Ok, so you'd probably want to define a game mode and set it up so you have No pawn class.

And set up whatever other classes as you need.

[viscid viper]

ok but what should i do next?

[lunar sleet]

Did you do that?

[viscid viper]

yep

[lunar sleet]

So whenever you mouse down, it stops tracing down to the map. But it works normally? Where are you calling this custom event ?

[viscid viper]

im calling the event in the controller when the mouse is pressed i set the custom event

[lunar sleet]

So you haven’t tested it when the mouse is not pressed

So the issue prly has nothing to do with that

[viscid viper]

i try to test it whout hiting the mouse but still doesnt work

[random pulsar]

nice it helped appreciate it

[tropic marlin]

In my blueprint, I'm unable to get an AI controller for a character that has one defined. Here's a screenshot of the blueprint as well as the AI controller on the pawn if that helps

[rugged wigeon]

check auto possess ai @tropic marlin

under class defaults

[tropic marlin]

It's set to "placed in world", and this is a character that exists alreadyu in teh scene when the game starts. I tried changing it to "Placed in world or spawned" but that didn't help either. Still getting a not valid on my getai controller

[waxen fog]

can you use a switch on an enum in bp?

[trim matrix]

yup

[waxen fog]

how?

when i drag off of it and type switch nothing comes u

or if i try to plug enum into int switch it doesnt work

[trim matrix]

you mean switch as in?

[waxen fog]

yes

[trim matrix]

no, what kind of switch are we talking about here?

[waxen fog]

nevermind i figured out how to cast it

[trim matrix]

to get the first one you simply enter "switch on <enum name>"

in the node adding window thing

@waxen fog

[waxen fog]

thank you

[lunar sleet]

@trim matrix https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/Paths/GetBaseFilename/ for your previous question

[trim matrix]

... i know i've said i found it

although thanks for ur efforts

[lunar sleet]

Oh, may have missed that

[trim matrix]

this is why i deleted the messages

[waxen fog]

for some reason this doesnt show up for me. was there some property u needed to check in the enum?

[trim matrix]

what's the name of your enum?

@waxen fog

[waxen fog]

nvm got it working

thank you for the help

[trim matrix]

may i ask what was the problem?

@waxen fog

[waxen fog]

well i created the enum in cpp, and I needed to add a flag that said it could be used as a blueprint type i guess UENUM(BlueprintType)

[trim matrix]

ah, kk 👍

[modern radish]

I can't figure out what I'm doing wrong here. How to get rid of this NOTE?

I can't turn off Pass-By-Reference in the Event Dispatcher

[lunar sleet]

Hit compile

[modern radish]

This is after compiling

[lunar sleet]

Mmm

This dispatcher you’re calling, it’s in the same blueprint ?

[modern radish]

yes

it seems to be a bug with Array Inputs on dispatchers

[lunar sleet]

So why the need for a dispatcher then

Yeah, I haven’t tried to pass arrays through dispatchers

[modern radish]

Sorry, no The dispatcher is in this BP, and then I bind it on another BP

[lunar sleet]

Ok, well maybe just try to pass the value rather than an array, if the use case allows

Otherwise you’ll likely need to try another form of bp comms if it’s a known issue

[modern radish]

I really can't fathom how this can be a bug, there's people complaining about this exact thing since 2015

Unless I'm making something wrong.. shouldn't I be able to disable pass by reference? why is it grayed out?

[nimble talon]

hey, i have this main menu i'm working on, and i want the snake in the background to always move in the direction of the red sphere (physics are enabled, it uses physics contraints for the other segments)

how would i go about executing this?

[lunar sleet]

Prly because it’s an array

[nimble talon]

the red sphere is an actor BP class

[lunar sleet]

Again, before you go down this rabbit hole ask yourself if you really need to be passing a whole array

[lunar sleet]

Does that red sphere get moved around by the mouse or what?

[nimble talon]

no

it just rolls around

its just supposed to be something in the background of the main menu yk

[lunar sleet]

Right, but is the green thing supposed to move to it across the map?

[nimble talon]

yeah

[modern radish]

Thanks, yeah I will work arroud it for sure

[lunar sleet]

Idk I mean I’d say use a navmesh and AI movement but idk if that’s worth it for a main menu

[uncut condor]

hi, how to access "Anim BluePrint" variables through a BluePrint?

[trim matrix]

cast to it

[lunar sleet]

Mmm… I think you’re supposed to do it the other way around

[uncut condor]

is it possible?

[lunar sleet]

Afaik you need to do things in AnimBP and access the character from there not vicerversa, so yeah

[uncut condor]

k will try

[tardy prawn]

can anyone screenshot your default blueprints node settings in horizontal and vertical ?
cause i made it not correct and can't return to default

[nimble talon]

theres no easier way to do it like making the head always face the sphere and always move in that direction?

[trim matrix]

I have a few questions regarding the save game object.

1. Is it a "good idea" to put functions inside a save game object?
2. Do ALL variables from the save game object get saved, or only the ones marked as Save Game?

[uncut condor]

maybe there is a link video? will be much appreciated 😃

[viscid viper]

does anyone know what to do ?

[trim matrix]

to get the dir vec facing the sphere do (sphere.worldlocation-head.worldlocation).normalize

[lunar sleet]

Or just find look at rotation

[trim matrix]

and what do you then do with it 😀

[lunar sleet]

Set rotation

[trim matrix]

and?

[lunar sleet]

And then you’re facing it

[trim matrix]

it won't make it go in that direction

[lunar sleet]

.

Did that involve movement?

[trim matrix]

also im pretty sure you wouldnt be able to see the rotation changes on a sphere

[trim matrix]

yeah, you can add that to the current loc

[lunar sleet]

Eh, arrow component, next 😀

Tbh the “simplest” way is prly a BT

It has rotate to face and move to tasks out of the box

It’s just a lot to learn to just make a main menu if you don’t already know how AI works

[trim matrix]

🥺

[lunar sleet]

1. Probably not

[trim matrix]

why

[lunar sleet]

What is the purpose of saving a function?

It’s not like it disappears whenever you reload

[trim matrix]

i dont want to save a func

i just wanna have it in there

[lunar sleet]

That’s what save game object is for

To save things so they can be brought back to life post-exit

[trim matrix]

i want to have it in there so i can do my save-specifc logic

[lunar sleet]

I see what you mean but given that you have to create it, I think you should look at it like it’s a widget

As in don’t keep logic in it if you can avoid it

[trim matrix]

:/

[lunar sleet]

Rather do that stuff in GM

[trim matrix]

i'd like to have my save game as self contained as possible (uhh working in a team, something, something, least amount of dependencies)

[lunar sleet]

Have you read this yet? https://docs.unrealengine.com/5.3/en-US/saving-and-loading-your-game-in-unreal-engine/

[trim matrix]

just now 🙃

didn't help at all

also they could have at least updated the text

[lunar sleet]

Yeah, get used to that

[lunar sleet]

You have blazingly fast reading skills 😀

[trim matrix]

thanks

🙆‍♂️ guess i'll just have to look at the cpp code

ok, forget all the things i've said here

got my crap figured out

[dreamy vigil]

I have a tank that is rigged to have two bones, one for the main body and one for the turret atop the body.

I want to follow the mouse movements and have the turret turn so the shooting bit is always facing the mouse location (it is an overhead shooter game).

How can I rotate the bone in the tank Pawn's Controller? At the moment I convert the mouse position to world position during the Tick event, but I can't seem to be able to get to the tank's bones so I can turn them/calculate the angle needed to have them look at the mouse position.

How can that be done in a BP?

[viscid viper]

does anyone knows why i cant get mouse position in any way?

[lunar sleet]

You know how to use a breakpoint?

[trim matrix]

what would be the best way to store constant values for bps? I saw some manics do that with structs (set default values in the struct, they will propagate to everywhere you make said struct)

[lunar sleet]

Constant values? What are you trying to do?

[trim matrix]

have constants shared between classes

[lunar sleet]

For what purpose

[lunar sleet]

@viscid viper this was for you

[viscid viper]

of course i do i tried to debug it but there is no reason as to to why the get hit result under cursor by channel wont only return 0 and the bool return false

[trim matrix]

so they could access the constant values without the need to modify them in every bp class

[lunar sleet]

Ok so does it stop on the breakpoint ?

[viscid viper]

yes

[lunar sleet]

And when you hover over the values after you passed the node that’s when you get 0,0,0 and false?

[viscid viper]

yes

[lunar sleet]

🤔

Let me check my proj

[lunar sleet]

Just use variables with default values, OOP will handle it

[trim matrix]

have you read my message?

🤔

[lunar sleet]

I did. Maybe I’m misunderstanding what you’re trying to achieve

You seem to be trying to use cpp functionality in blueprint, so far though it seems like you’re just complicating things for no reason, like with the save game thing, but then again idk much

[trim matrix]

does anyone know how i can make an UI generate from a data table that i already got

[lunar sleet]

Did you turn off trace complex yet?

[viscid viper]

yes its turned off

[trim matrix]

i want to have a constant, which can be accessed by all bp classes. i don't want to go through the effort of making said constant in every bp class that uses it, because if i wanted to change it at some point i'd need to go through each one of those bps classes and modify it there.

global constants

[lunar sleet]

Put it on event tick and see if it works anywhere on the map, unless you said you tried this

[lunar sleet]

Afaik, constants are cpp only territory

Couldn’t find anything indicating otherwise

[viscid viper]

event tick does work

[lunar sleet]

In that same spot too?

You could always ask the #cpp crew to confirm @trim matrix

[viscid viper]

on the screen ? i am always trying several diffrent spots the event tick give the values for them but not the event when i click

[lunar sleet]

Right, so it works fine everywhere normally. But when you click it doesn’t

Show your mouse click event

[lofty rapids]

that condition will most likely always be true

because your dragging from a set

thats to true idk if thats the live value

if you release before the delay, what would happen to that value ?

[lunar sleet]

And also, did you try it on press instead of released ?

[stable wedge]

what numbers would I have to put in the last two range and greater and less than to make one of them be for upwards rotation and one be for downward rotation

[lunar sleet]

No idea. Who made that get forward movement and what’s in it

[stable wedge]

get forward movement is controlling the character up and down movement

[trim matrix]

what kind of insanity is that?

[lunar sleet]

Ok, well that’s a non-answer but I’m guessing they’re using dot product ?

I don’t really want to speculate as to what the input should be

[stable wedge]

Idk ask my professor

I think I found out the problem with it but need to add controller input to test more to see if it breaks with that

[trim matrix]

hmm... tbh i've seen bps that were much worse

my old bps.

[lunar sleet]

Your professor made that random function that we are not privy to?

I guess they do say if you can’t do, teach

[trim matrix]

might post a glorious screenshot of them 1 day here

[lunar sleet]

Structs masquerading as DAs and no variables to speak of? 🙃

[trim matrix]

you guys totally should see how i made a randomizer

[lusty oak]

2 questions. 1. how can I trigger something on my level blueprint via an On Component Begin Overlap event on my player character blueprint? and 2. Should I even be doing that and if not what is the better way to handle it? For some context, I have a collision box around my player and if an enemy gets close enough, it triggers combat. The combat is somewhat similar to pokemon, but takes place on the same screen. Player does not move character during combat but instead issues commands. I need the level blueprint to manage combat.

[trim matrix]

1. don't use level bps. 2. don't use level bps, try doing it with a game mode instead. Or anything else, just not the level bp

[lusty oak]

Ah ok, I don't have much experience messing with game modes. But, I guess based on the name that makes more sense. Thay said, could you point me in the right direction for how I would trigger something like that? I'm still a little fuzzy on how some blueprints interact with other types of blueprints.

[trim matrix]

🤔 maybe it would be best to do that in the player actually

and from the enemy bp call an event on the player

@lunar sleet What do you think 🙃 ?

[winter tiger]

This might be a silly question but is it possible to watch when a function in a bp is called when you have a component attached to it, without using a dispatcher or interface?

I have an actor component, I'd like that component to know when a specific function with the actor it is attached to fires. If it is possible to not edit any of the code in the primary actor that would be ideal

[trim matrix]

for an event, you could bind it

for a function, rather use an event dispatcher

[lusty oak]

I feel like you're right that the battle system should be handled by game mode as it will be switching player controls, moving the camera to a battle position, handling UI, etc. I'm just not sure how to actually trigger the battle since it's based on proximity between the player and the enemy. Unless the On Component Begin Overlap on the player could simply trigger the game mode to switch to battle mode, and then the battle mode OnBegin would be able to grab the data it needs from objects near the player and setup the battle... that might work.

[fiery swallow]

no

[winter tiger]

Ok, that's kind of what I figured. Thanks

[lunar sleet]

Should definitely watch the bp comms video pinned here if you haven’t

[lusty oak]

Oh cool I dind't know those videos were all pinned there! Thanks!

[noble ledge]

I have a node for "Create XXXX Widget" and it has pins to different members of that widget. Is it possible to add/remove pins to it to other members?

[lunar sleet]

no idea what you mean, maybe show code

[noble ledge]

This widget has more than just those members. I wanted to add more to this so that they can be set when created

[lunar sleet]

those are not normally there, they just show up because whoever made the widget exposed a bunch of variables in it

so if you want more to show you have to go to the widget, create the new vars and expose them

[noble ledge]

Ah i see

i get it. Thanks

[lusty oak]

Is it not possible to change game modes in the same Level while playing?

[mental trellis]

Don't think so.

[lunar sleet]

Not afaik either

But changing the actual game mode seems unnecessary

What’s the use case ?

[mental trellis]

You could do different modes within a single game mode by using a game mode itself as intermediary between other mode handling objects. Something like components which you can switch control to.

(and game mode can have components, it's just an actor)

Tbh I have a lot of random game ideas like that. I should make them one day and put 'em on the marketplace.

[mild ibex]

Why does the Add {whatever} Component only add one component, shouldnt it add multiple? Im checking the number with the get num children node coming off self.

and is there a way to add multiple components?

[lunar sleet]

why would it add multiple?

[mental trellis]

Run the same node multiple times?

[mild ibex]

well the title of it makes me assume every time the node is fired it adds another component to the target

unless you put a do once in front of it of course

[lunar sleet]

it adds one component per execution, not sure what title you're looking at

or what that text 3d component node even is

[mild ibex]

the title of the node, and the node itself is just the add component, at first i was using add component by class, then saw there was just an add [existing component] component node

[mild ibex]

that doesnt seem to be the case for me, either in editor or at runtime, when I fire the custom event it only ever adds 1?

[lunar sleet]

how many times are you firing the custom event?

what's calling it

would prly need to show the rest of the code

[mild ibex]

right now nothing technically, the custom event is shown in editor, where I can fire it, then in play mode, i just select the actor and press it there to fire it, and that custom event goes directly to the add component so nothing is between them either

[lunar sleet]

press what there, you have like a button widget or wdym

[mild ibex]

for custom events the Call In Editor option

[lunar sleet]

oh, that sounds like some blutility thing, not sure that's even meant to be used like that, but maybe

you can always put your code on tick and run, see if it starts spamming components 🙂

[mild ibex]

will try, I saw something similar on the Forums relating to blutility, thought it was handled different when in game but let me check.

[lunar sleet]

afaik blutility is for using tools during editor time (construct)

[mild ibex]

still doesnt work, replacing the custom event with a simple Num 5 for input does the same thing in play mode

if I uncheck manual attachment I see the number go up like its supposed to and I can see the names of the children, but I cant see them in the viewport :(((

which was the same for custom event

[lunar sleet]

haven't used that node before, not sure

[mild ibex]

All good, just gonna keep at it and see what works

[waxen fog]

Hey is there a way to access a static version of a class in bp?

[frosty heron]

Get class default

[waxen fog]

is there a way to do this with a pure function?

[red berry]

Is there a way to have actors have their meshes visible in the editor, but when the game starts, they are loaded asynchronously?
Currently the player and NPC all load their meshes async, but its not visible in the editor and its hard to iterate and know which NPC looks like what
Edit: Is there an Editor Only node you can put?

[frosty heron]

It's already a pure function

[waxen fog]

i mean a pure function inside the class, is there a way to get the return value of that without needing an instance

[dawn gazelle]

You mean you want to create a static pure function within a blueprint class?

[pulsar moss]

I'm writing a save/load system that includes player velocity (like if they were falling). It's not working and I'm not sure why.

Upon level start + load I set the player's velocity (which I logged out and verified as saved)

but it seems like teleport, then set velocity, doesn't seem to work

[dawn gazelle]

From what I understand, velocity on the CMC is a calculated value, not something that you can impart on to the character.
(Guess I'm wrong about this!)

[pulsar moss]

it's definitely something I can set from my testing. This works, for example

[dawn gazelle]

Doesn't like it on the Z axis though.

Set movement mode to falling.

Then it'll take a Z value.

[pulsar moss]

ah so I need to save the movement mode as well

but still, setting velocity, adding force, does nothing

impulse velocity works 😐 but the values are wrong

@dawn gazelle that was it thank you 🙂

[dawn gazelle]

Did this as a test on my character, seems to teleport & impart the velocity on to the character (looks like they jump sort of) whenever the button is pressed.
Tried doing it on Begin Play too and same result.

I learned something too, so thanks 😄

[pulsar moss]

movement mode had to be set correctly, even teleporting to mid-air

otherwise the set velocity does nothing

it does pollute my save game state a bit, oh well

[red berry]

Why does setting a Primary Data Asset variable from object to soft object cause a crash?
Edit: nvm it doesnt crash if I close every other tab somehow.
Edit2: now my whole project crashes if I try to run the game

[lunar sleet]

I would move this post to #audio

If not, #packaging

Whats the best way to manage an array? I'd like to be able to edit and extract the array in different Blueprints.

I'm using an array to manage my decklist. I'd like to be able to have a draw function call the deck list, and remove the top card from it (index 0). But right now, my array is just a variable in a single widget blueprint.

[lunar sleet]

Prly put it in the GM or somewhere easily accessible

[solemn basin]

I have a working soft object reference and async loading for my items, but I want to also see their mesh in the editor. Will the construction script get in the way of async loading? If the construction script works, then why do we even need the async node?
Edit: I tried making a macro that does Async loading, and try to call that from the Construction script, but its not working

Should we even have soft object references for static meshes for items? Its either I have good runtime performance with async loading, or fast and easier prototyping in the editor. I can't seem to have both.
I dislike how every unreal expert says to always use soft object refs, but if I try to include them in my code, I get clunky code that is hard to prototype with

[elder lodge]

how can one profile blueprint performance, # of calls, time per call, etc?

[lunar sleet]

Async loading is for runtime, not editor time

Construction script happens during editor time so trying to async there is pointless

You don’t have to soft ref and async everything, but it’s good for heavy asset loading while the game is running, because otherwise you’ll get hitches

Especially useful when programming for mobile and similar low spec devices

[lunar sleet]

See #profiling

[red berry]

Then how do I have async loading in runtime, but I can see the object in the editor?

[quartz spoke]

is there a way to get the location of the points on a spline? They aren't showing up in the blueprint debugger :\

I'm adding the points at runtime fwiw

[red berry]

I think I figured it out. Simply add your normal async loading functionality for the static mesh for the item actor. This is with the Mesh Component's mesh set to nothing.
Then give the item actor an empty Editor only Static Mesh.
Then in the construction script for the item, check if "isPackagedForDistribution" and if it isn't (its assumed to be a development build), set the mesh for editor only, and hide it in game.
I havent tried yet in a live build, but I'm sure that this development code wouldn't run, so it won't slow down the production build. And we get to see the preview for the items in the editor.

Edit: In the dev builds, I'm assuming the async loading code is pointless because we cast the soft object ref to an actual (hard) object ref, so its forced to load synchronously on object creation. In this case, the async completes almost immediately because the object is already loaded.
In production builds, this shouldn't happen and it should load the objects async properly, where it could take a few miliseconds, because it hasn't been loaded prior.

[mental trellis]

I've you've got the asset referenced in the editor or you're looking at it or clicked on teh asset or whatever, it's probably already loaded it into memory.

That doesn't happen at runtime because there's no editor there to give you freebies like that.

... I may have misread what you said, but still.

[coral star]

When I export the texture file from the unreal engine via "Export to Disk" node I got tiny little black image... but after opening the texture in the engine exporting again I could get the correct image.. Does anyone know how to fix this problem?

[mental trellis]

Loading the asset may take more than few milliseconds if it's a large one.

[red berry]

Thanks for the clarification. I think my code still is beneficial because if you suddenly walk into an area with 1000s of items, the game will stutter as it tries to load the meshes in the main thread (this is how most people implement items normally, without the use of soft object references). My code aims to prevent that as it will async load the assets slowly over time while allowing the player and everything else to render (I think). At least the player will still be able to move around

[coral star]

How can I wait untill load is done?

Should I uncheck the async option?

[mental trellis]

That's definitely a good approach.

[dawn gazelle]

If you keep async on, I imagine you can hook up an event to the on Complete pin like this and that'll probably trigger when it's done.

[coral star]

And call the export to disk again?

[dawn gazelle]

If the things are already loaded into memory then async load doesn't really help and when you say 1000s of items, I imagine that many of them are duplicates of other things or would have assets that are shared among them.

If you have an actor that is beginning play and you haven't loaded one of them before, then that actor typically already needs most of its assets ready to go, so there's little benefit in async loading its assets that are needed immediately if you are spawning that actor anyway.

Where soft refs and async loading shines is when you have a class that may need to reference an asset, but not necessarily going to be using that asset immediately, or has a reference to a data table (which can hold hard refs to assets forcing them to load which means you should use soft refs in data tables), or data assets (same), which again you may not necessarily need them loaded at the time the actor is loaded, if at all. You're then free to load the assets only if absolutely necessary.

What you're attempting to do sounds more like something that World Partition may be able to handle for you, in which case you don't load all the actors placed in your game all at once, only sections of the world need to be loaded at one time, and it can even be used during editor time from what I understand, so you only need to load parts of the map that you're working on.

[dawn gazelle]

I'm not sure what you mean by calling it again. You'd call Export To Disk once, and if you hook up that event like I showed, that event should trigger when the export is finished and you can do whatever you want from there knowing its finished.

[coral star]

The problem is that the image is not exported properly until I opened the image inside the engine

Before opening the image as you can see above it gives me a tiny black image

I fix this issue just forcing the editor to open editor view and then close it.. I don't know is it right approach.. anyway it works now

[trim matrix]

i think changing the image format in the export node fixed it

The image saving to a black square i mean

[coral star]

Oh what format should I use?

currently I am using Userinterface2D

[trim matrix]

oh wait nevermimd, i looked at daturas pic

[red berry]

Which approach should I take when it comes to "switching" between a static or skeletal mesh component, for an item actor?

1. I keep static and skeletal both separate, when I need to disable one, I'll just remove the mesh ref (keeping the component), and move the hitbox to the other one.
2. Same as 1, but each has their own hitbox, so I don't have to move it around.
3. I put Skeletal underneath the Static, that way their positions are in sync.

If I do 1, there's a chance that the items won't be aligned together in their position. Only 1 will be visible at a time anyway, but its possible in rare cases that just as the static gets swapped for the skeletal, there can be a physics impulse, which can ruin the trajectory of the item. i.e. the item can be thrown somewhere (impulse to the static one), but then halfway takes a 90 degree turn because some other physics effect was applied to the skeletal one

[tribal gazelle]

I have a pawn which is a ball that rolls. Is there a way to detect if it is actually rolling/moving?

[modern radish]

I want to trigger some animation when I delete a UMG child from a scroll box.. I'm using the Remove Child node, but that doesn't seem to trigger Event Destruct

[steady night]

Hey Guys Question

i got this variable changing somewhere at the begining of the game , but i cant use find referense on where since its changing from somewhere else

any advice on how to locate where its changing ?

[trim matrix]

In the docs they say event destruct only gets called when the widget is no longer referenced (eg. gone from screen)

Consider using a delegate or calling a function on the widget to firstly play the animation and then after the delay of its duration run the remove from parent node

[trim matrix]

In ue4 there was a rolling ball template. To check if it is rolling you could get the vector length of its velocity

[dreamy vigil]

I have a tank that is rigged to have two bones, one for the main body and one for the turret atop the body.

I want to follow the mouse movements and have the turret turn so the shooting bit is always facing the mouse location (it is an overhead shooter game).

How can I rotate the bone in the tank Pawn's Controller? At the moment I convert the mouse position to world position during the Tick event, but I can't seem to be able to get to the tank's bones so I can turn them/calculate the angle needed to have them look at the mouse position.

How can that be done in a BP?

[tight pollen]

someone?

[jade lintel]

what are you trying to achieve

[steady night]

Hey Guys Question

[trim matrix]

what is the question?

you are doing a trace downwards in front of the actor

@steady night

[steady night]

yeah

drew a picture

so now im casting a distance at facing direction

how would i cast it in a random 360 degree

instead of facing direction

insated of the "Get actor forward vector"

i would get random degree 360 something

no i mean there will only be 1 ray

the picture is just indicating that it would be random

so only do 1 cast at random degree angle from actor basicly

[trim matrix]

random float in range 0,360

plug that into make rotator Z

And rotate the forward vector by it

[steady night]

from the forward vector ?

huh :/ ?

[floral stump]

is it possible to spawn projectile on muzzle location and move it toward the place where the cursor is aiming?

[jade lintel]

Yes

Line trace > Get rotation towards the trace end > Use the rotation to spawn projectile

[bleak summit]

is there a way to make this widget component not be hit by 3dWidget trace channel?

[trim matrix]

get yourself a random float in range node, in it make the range to be from 0 up to 360

then get this node https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Math/Vector/RotateVector/

Break the rotator in it and plug the random float into z. Then get your unmultiplied forward vector and plug into the rotate vector. Finally multiply it by your constant to extend it and use it in the same way you were using the forward vec before

[floral stump]

can you show me a basic pb code for this?

[gentle urchin]

pb ?

FindLookAtRotation(Muzzle Location, Target Location)

[floral stump]

bp *

[trim matrix]

@steady night

idk how i could break this down even more tbh

[steady night]

@trim matrix

yeah no this is a simple problem tbh way below even me 🙂 but when your brain overthinks stuff everythings impossible😅

[jade lintel]

Here

assuming you meant you meant crosshair with cursor

How it works: It makes a line trace, if it hits, it get the rotation towards the hit point from the trace start, if it doesnt hit, it just takes the trace end and gets rotation towards it from the trace start. Then it spawns the bullet actor with the rotation it calculated

[floral stump]

so it will spawn a bullet at the crosshair even if my crosshair is not at the center of the screen?

[jade lintel]

it uses the camera so it will always spawn it at the center

you can add an offset if the crosshair isnt centered but that might take a little tweaking

[floral stump]

yeah my crosshair is isn't at the center

[jade lintel]

add some offset at the camera location vector

[floral stump]

i will play with it to replace the camera with the crosshair attached to the camera

[jade lintel]

is the crosshair 3d?

[floral stump]

it is a widget containing image for the crosshair

[jade lintel]

If it isnt offcentered on the image itself then it should be fine

[bleak summit]

Why does my aicontroller not get reset when i reload a streamed level?

[tight pollen]

I'm trying to achieve what I wrote, I just want to be able to resize the box by changing the value in the float variable, and the box must resize from center

[jade lintel]

you want to change the size x on runtime

?

[tight pollen]

yes

but so that it is even on the right and left sides

[jade lintel]

did you try using this

just change the x value and leave the y to 1

[tight pollen]

i don't want scale

[jade lintel]

then what

[tight pollen]

it must be a combination of the values ​​in "Position X" and "Size X"

[jade lintel]

set alignment

then you wont need to change the position

[tight pollen]

I forgot about alignment

thanks

[carmine thunder]

can we reference an object present in a scene to another object present in the same scene?

I mean reference this `UPROPERTY(EditAnywhere) AActor* refActor'

[steady night]

@trim matrixhmm dosent work :/ whats wrong ?

[trail wyvern]

Is there a way to batch multiple Async Save Game To Slot triggers? Use case: we have different events that can trigger a save and want to avoid a potential race condition by either batching or queuing the saves.

[trim matrix]

what happens?

is it not a straight down line?

@steady night

[trail wyvern]

Yeah - possible. Change the macro to this and then you can select the actor from the dropdown in detail section when selected in the outliner.

UPROPERTY(EditAnywhere, BlueprintReadWrite) 

[north lynx]

Hi!
I'm trying to close the widget on click of the button, but for some reason, everything works except for removing the widget from player's vision
Can anyone help me with this? For me everything looks ok

[carmine thunder]

did this and tried to assign the actor. It still stays none

[trim matrix]

why are you removing it directly after it gets added?

[heavy lion]

Anyone know how I can set what is inside a named slot in UMG?

[carmine thunder]

want it like this

[steady night]

@trim matrixhm i dont even se the line trtce whattahell

[trim matrix]

draw it with persistent set as the debug line duration

[steady night]

yeah i do i cant se it

[north lynx]

Like, idk
I learned that if I don't want the log to go red as heck I need to check if var is valid and then go for removing from parent

[trim matrix]

don't remove it in the same exec flow line as it gets constructed

[carmine thunder]

can someone help me with this

[trim matrix]

there's no point in doing that

[north lynx]

Ok, I'll remember

[trail wyvern]

Share some surrouding code / blueprint where Scene Actor is being defined and used for context

[north lynx]

Still, the note is not removed from the view and I don't know why

[carmine thunder]

not using it anywhere yet.
I want it to get ref

this is how i have declared it

UPROPERTY(EditAnywhere, BlueprintReadWrite)
    AActor* sceneActor;```

[trim matrix]

you need to add it to viewport

after it gets constructed

[floral stump]

works perfctly, thank you very much

[trail wyvern]

You see nothing in the dropdown when expanding (in the outliner)?

[north lynx]

But...
I have the working code for adding the note to the viewport, this code above should close the note, but is not removing it from the view
That's my problem

[carmine thunder]

i see thing but when i select it it still remains null. Even when I have selected an actor

[trim matrix]

How are you adding it to viewport?

Maybe you are doing it multiple times

@north lynx

[tough atlas]

Thoughts on using mass amounts of blueprint classes with static meshes for a destructible voxel like landscape? Is there a way only have actors active or turned on within a radius of the player to save performance

[trim matrix]

Why are you setting the ref in 2 different places?

[trim matrix]

if the widget is valid here it will duplicate it onto the screen every time that event gets called

[north lynx]

I have Interact system that works inside of actor
This code for opening note is in the actor class and works only if player interact with it. That adds the widget note to the viewport of player
The code for closing it is in the ThirdPersonCharacter Blueprint because I need to get input for closing, anytime

At least that's my logic

[trim matrix]

you should be adding the widget only when u create it

[north lynx]

And that how it works i guess, when I interact, I'm checking if the REF exists, if not, it creates one so then if exists, I'm adding it to the viewport

[trim matrix]

no, do it ONLY after the construct node

Not anywhere else

[north lynx]

And how the construct node works?

[trim matrix]

Sorry, i meant the create node

[trim matrix]

If the widget is already being displayed, this code here will duplicate it when it gets executed

[heavy lion]

https://docs.unrealengine.com/5.3/en-US/BlueprintAPI/UIFramework/SetNamedSlot/
I cannot find this node in blueprint at all.

[north lynx]

So how can I get this NoteREF in ThirdPersonCharacter Blueprint from Note Actor?

[thin panther]

Holding the reference to the thing in the thing is pointless

Store your note ref elsewhere

[trim matrix]

@thin panther all they need to change is that part

the widget can be added to screen multiple times if it existed already

[thin panther]

There is a fundamental lack of understanding on what casting and referencing is displayed in that screenshot

[trim matrix]

I still don't get why would you construct a widget and NOT display it on the screen

[trim matrix]

.

[trim matrix]

move that AddToViewport to where you set the widget reference

in both places

[north lynx]

Okay, somehow I resolve my problem
Thank you for your time 🧡

[pulsar vigil]

hey guys insane simple question for a noob : how u limit a value in an array with one indexc like i want it to not go sub 0

[lunar sleet]

Arrays do not go below 0 index unless there’s nothing in them

Technically they don’t go 0 index at all

[pulsar vigil]

not the index the value but its great knoledge

[lunar sleet]

But find will return -1 if no results

[lunar sleet]

Then what

Yeah, if you mean each element 👆

[pulsar vigil]

yeah that look like the answer

[lunar sleet]

At that point you might even just set to 0 if you do the < check

[pulsar vigil]

yeah true

thx guys i come back if i fucked up

[dark drum]

have an array input on the macro that's pass by ref.

[sick sky]

example

there is also the "assign" node

yup

i have a good memory of where my assets are located :)

line an enum, is there a trick to make the existing names shown like this for a event name input?

[sinful forge]

i am trying to align my character to a wall hit by a line trace. right now i got him to face the wall by setting the rotation to be the Hit ImpactNormal * -1.f but how do i offset the location by a determined amount regardless of the side of the wall he is facing so for instance he'd be 45 units from the wall ?

[hearty sand]

Hit.Location + (Hit.ImpactNormal * 45.0f)

[hearty sand]

wouldnt -45 make him 45 units into the wall

[versed sun]

hmm... maybe ?

[sinful forge]

that's it thanks 🙂

[lunar sleet]

I don’t understand the question sry.

[versed sun]

wants to populate the dropdown box with the row names

[sick sky]

what i mean is,
when calling the event, make that instead of <screen> a list appear,

so i dont have to always see what is the exact name

like an enum, you can "pick" the value you want

[frosty heron]

Let's be logical here. What's the criteria for the drop down?

[sick sky]

i dont think what i am asking exist tbh, i would mean that the event knows what data table is used

[frosty heron]

It's a strange feature idea to suggest

Maybe you can use gameplay tag instead

That might have a drop down I'm not sure

If you need the name from the data table, just pull get all row name node

[sick sky]

yeah i see

[sick sky]

yup but if you use the row name as an input in some event it will loose the list

because it doesnt keep the context ig

[versed sun]

are you changing datatables ?

[sick sky]

no

[versed sun]

What UE version are oyu

[sick sky]

wdym by changing ? in UE5 with no plugins DT are static

[sick sky]

5.2

[versed sun]

didnt know if you were trying to do this

cause it dosnt like that

[sick sky]

no

you miss my question :)

but ty for trying

[lunar mulch]

I have an event that starts an animation, i want it to switch to a different one every time. ( 3 different ones) Now currently im using an Array with 3 Animations, using a get node into a Random integer by range. However i dont want it to be random. I want it to go like this 1-2-3 -1-2-3. Basically play all 3, and then start over from the start. I cannot find the right wording for what im trying to do so, so no google searches or documentation has found the answer for me. What nodes could i use to achieve this?

[sick sky]

btw this is possible

but you need an exisitng row

[lunar sleet]

Increment an integer from 0 to 2, then when it reaches 2, reset it to 0

Use that int to grab the index in that animation array

[versed sun]

Wrap (Integer)

[lunar sleet]

I didn’t know that existed 😅

[versed sun]

i learned of it a while ago after manualy doing it the hard way

[lunar mulch]

Hahah love the documentation as an amateur " Returns Value between A and B (inclusive) that wraps around

Target is Kismet Math Library"

[lunar sleet]

Hehe

[lunar mulch]

dafuq does wrapping around mean lol

[lunar sleet]

Pretty much what it sounds like

[versed sun]

if it more than Max, set to Min

[sick sky]

its like a "in range" ?

[lunar mulch]

okay thank you that makes sence

I guess the value is the value it changes every time its triggered?

So, value set to 1, it changes 1 step every time it is trigger?

Value set to 0 it doesnt change?

Or am i just a complete idiot

[versed sun]

this will cycle 1-2-3-1-2-3

[lunar sleet]

It will cycle 1,2,3,4

You want 0 to 2

We’re talking array indices

[thin panther]

we are also delaying on tick which is not great

when we could use a timer

[lunar sleet]

Ah hadn’t even noticed

[versed sun]

example for testing

[lunar sleet]

Ok, sorry misspoke what I meant was that’s not useful for array

You want to start at 0

Because array indices are 0 based

[versed sun]

oh yes , of course

but they asked for 1-2-3

get milk, and if the have eggs , get 6
comes home with 6 milks

[lunar sleet]

Right, but he’s cycling through an array, so 6 eggs means the 6th egg is index 5, first egg is index 0

It’s our job to correct him 😀

[lunar mulch]

Sow hat are you using as your value in in the variable?

[lunar sleet]

Yeah, def this too

But for them they shouldn’t need a timer or tick prly

[lunar mulch]

Nah

[lunar sleet]

Just increment every time you’re done with an animation

[lunar mulch]

Its just for a idle break animation

Im trying to understand the code he described

[lunar sleet]

Basically, start at 0, ++ , wrap int with min 0 max 2, done

And then just use that resulting value to pull the index from your animation array

[versed sun]

removed the tick

[lunar mulch]

damn, this is all just to get a code going from 1-2-3-1-2-3?

I didnt realise it was that complicated

[versed sun]

no no no

[lunar sleet]

It’s not lol

[versed sun]

ignore

[lunar mulch]

Ah okay, i am lost i was following those screenshots hehehe

[versed sun]

sry

[lunar mulch]

Okay so just a question, what is the value they want from me inside the wrap integer?

I understand the min-max

But i don't think i understand what the value is supposed to do. I thought i did, but i just tested my theory and it's incorrect

[lunar sleet]

It’s just the incremented value. The wrap just keeps it from going over the Max

It “wraps back around” to the Min when it goes over

0,1,2 , increment again, rolls back to 0

[versed sun]

i think you want this

[lunar mulch]

Hehe i was just about to post this, guess im on the right direction

[lunar sleet]

The min has to be below the lowest value?

[lunar mulch]

Just curious, why do we have to set the Animation Index?

Instead of plugging it straight into the get array

[versed sun]

i think so it makes it work

[lunar sleet]

So that next time you don’t start over

[versed sun]

keeping track of the previous index

[lunar sleet]

You want to cache the latest result

[lunar mulch]

Ah yeah that makes sence

[sick sky]

its cool seing many people trying to help a guy

[versed sun]

I hate "cache" cause I always read it Cash-A

[lunar mulch]

Yeah muchos gracias, im learning stuff here

[lunar sleet]

Read it as 💵

[lunar mulch]

Cash-ay

Like a fabulous way of saying Cash - Hey

[sick sky]

cash-array

[versed sun]

https://tenor.com/view/canada-day-john-oliver-mike-myers-raining-money-make-it-rain-gif-5598969

cash - ehh?

but anyhoo, did the Wrap -1 to 2 work ?

[lunar mulch]

Btw, this is brilliant but its not intuitive at all that the min has to be below lowest value :p

Im just imagining me in 5 hrs slowly figuring out these nodes by myself, but then not knowing that the min has to be below lowest value and spending like 2 days bug-testing that 😛

[versed sun]

need a c++er to see it it IS inclusive

[sick sky]

intuitive ?
programming: hold my kb

[lunar mulch]

hahaha :p

[versed sun]

i just search each variable type and got thru the nodes to see what exists

[lunar mulch]

Im just saying, u guys are a blessing and think of the things some new people in the coummunity would never think off.

[sick sky]

i dont remeber:
doest -1 as index gives the last index ? like in pythin ?

[lunar mulch]

Yeah thats what i was doing 😛

[versed sun]

ahh, and Wrap is at the bottom, you would have found it

🙂

I think Min is Exclusive ,but max is Inclusive....

[lunar sleet]

That’s a weird way of coding it

I just tested it

It’s weird, the first iteration gives 1,2, and then it goes to 0,1,2

[lunar mulch]

Yeah i did see it earlier, i just didnt understand what wrapping meant, im still learning the language of the unreal documentation 😛

[lunar sleet]

That’s with -1 Min, 2 Max

[frosty heron]

I prefer to do the idle in the anim instance

[lunar sleet]

I guess because my default value is 0 which makes sense

[frosty heron]

And not with a montage

[lunar sleet]

Yeah, if you do it this way and want the first animation to show up first, you’ll need your default index value to be 2

Because it always increments once before being used

[lunar mulch]

Id normally do it there too, but this is a very specific animation that only happens when trigger by a certain event, for sake of simplicity im just adding it after that event.

not your avg idle animation so to speak

[versed sun]

Start with Value of -1

[lunar sleet]

Or that yeah

2 would work too because the wrap

[versed sun]

ANY number besides 0 and 1

[lunar sleet]

Yeah

[trim matrix]

this is the thing you'all going on and on about

[sick sky]

i got a question

can i, when customizing my instance of a custom structure in a DT row:

decide a "var type" ?

for example:

for row1 i would like to use a integer, and the goal value is 3
for row2 i would like to use a vector, and the goal value is 20,0,99
for row3 i would like to use a boolean, and the goal value is true

the issue i also think of, is how to get this specific value when breaking the structure

i thought about using a object BP class or some other custom structures ?

[mental trellis]

Each row will use the same types.

[sick sky]

yes, but how can i make it possible to select what i want later on ?

[mental trellis]

You can't use objects in data tables.

[sick sky]

yes ill have to use structures

[mental trellis]

You could reference an asset, like a data asset, which has custom information.

[sick sky]

dam yes

ty man

[mental trellis]

Remember to use a soft ptr.

Np

[sick sky]

ptr ?

[mental trellis]

Pointer.

[sick sky]

ah a soft ref ?

why ? does it not work at all or is it a safe method ?

[remote meteor]

so you dont load the whole game when the game starts up 😆

[mental trellis]

Because you should always use soft pointers where possible.

[sick sky]

okay

[dreamy gulch]

Trying to call an event dispatcher to rotate target. Theirs action actor component on the character, and its child components are the separate actions, where i am calling rotate to enemy. The problem is that it only works with event rotate targeting the child components, not targeting the parent general action component. I have tried to custom event the call rotate so its called from the parent action component but the event on the characterbp) only fires when using the specific actions event. Can i have it fire related to the parent so i dont have multiple rotate to target events? It might be down to my component, ive already had to add each child i couldnt make it work with just the parent added

[floral stump]

is it possible to check if the impact point is out of range ?

[jade lintel]

what do you mean by out of range

[floral stump]

mean if it doesn't hit anything, incase if look at the sky what will be the impact point?

[jade lintel]

trace end

second from the last

[floral stump]

I have a laser which always point to the impact point

[edgy ingot]

Test it? Draw debug at location

[jade lintel]

yeah you can use a switch statement which toggles between trace hit and trace end based on if it hits or not

[jade lintel]

like in this example

[floral stump]

yeah this work for the spawn bullet, but I am placing the laser at the location where the bullet will be spawned

[jade lintel]

copy the part which goes into the Target pin for Find look at rotation

that value returns the last point of the trace either the hit, or the end of the trace

[floral stump]

for the laser setting the impact point directly works fine

I just need to limit it if the impact point is not in range just don't show the laser

[jade lintel]

oh

is the laser pointer a decal

[floral stump]

yeah

[jade lintel]

set its visibility to Hidden

a branch off of the return value of the line trace

on false > set it to hidden

[noble ledge]

Is it possible to find all usages of a struct?

[floral stump]

yes this works perfectly, thank you very much

so the return value is only true if the impact point is in range

[jade lintel]

yup

basically if ray hits something, it returns true, else its false

[floral stump]

great

[floral stump]

it hits a sky too?

[jade lintel]

nope

[carmine thunder]

here, one of the actor can be assigned but other cannot. Is there some property which doesn't allow an actor to get assigned?

[molten tinsel]

Can someone explain me what it does and if I need this in my character?
Because I want in player controller cast to character and use events like jump from there on some spacebar for example.

[lunar sleet]

It adds an #enhanced-input-system mapping context so you can use input

[molten tinsel]

hm, so it is required. So if I want to use it in player controller, I need to create it on begin play?

[lunar sleet]

It doesn’t need to be in the character, but that and the player controller are common places to put it in.

Yeah, or onPossess

If you’re making like an RTS or similar game where there’s no main character, player controller is prly the better place to put it in

Otherwise, character is usually the go to, as you want to add the inputs directly to it

[molten tinsel]

Well, I kill character and reposses on spawn and the cast to it breaks, so I thought ill move everything to player controller(since it will never get destroyed). But I wonder if there is difference between those two?

[lunar sleet]

You’re casting to the player controller not the character, so that won’t change anything

Try moving your code to Event Possessed instead

And also

On your character under auto-possess make sure it’s set to both placed and spawned

What could be happening is you’re never repossessing

[outer glacier]

Hey all. I have a blueprint lighting tool I made for myself andI am looking at putting it out on the Marketplace. Is there a way to lock a blueprint to prevent editing/copying of the contents? I am not too hung up on it, but I might like to make it a tiny bit harder to nick. I am aware of a couple of plugins for this, but I don't really want the complexity of being tied to another product.

[jade lintel]

there isnt

blueprint is made to be edited

[outer glacier]

Thanks for the quick reply.

[jade lintel]

it can be edited even in plugins too

if it exists locally, you can reverse engineer it

and this goes for nearly everything

[outer glacier]

Fair enough - just thought there might be a way to slow down casual copying but I don't want to make it a PITA for me or the user either. Thanks for the help!

[jade lintel]

you can always make the code intentionally unreadable but i wont recommend it 😂

[serene condor]

Is there a way to change the image in an image using blueprints? (The image is in a User widget)

[jade lintel]

yes

It should be set brush or similar

[serene condor]

Let me try

Oh my

Many options

Give me a moment

Yes. Got it. Thank you!

[serene condor]

How did you get all those settings

And I can’t connect any Set brush to my image

[jade lintel]

right click the brush pin

split struct pin

[serene condor]

Got it

Thanks

[jade lintel]

no worries 😄

[pulsar vigil]

Hey guys, how do u update a variable from a bp to his anim bp when u press a keyboard input ? what i can do for now is get the variable in the abp but not update every time i press my keyboard, and i would like to not use a delta or event tick

i tried with event and event dispatcher but i can't get it to work

[radiant bear]

this current logs the values but how log the values before decimal even if it's zero?

[lunar sleet]

Idk what you mean but also that branch is not connected

[radiant bear]

that's fine

[radiant bear]

the values looks like this 0.0000 something

i see .0000 but i also want to see 0.

[dawn gazelle]

Usually you'd retrieve values in the Blueprint Update Animation event in the animation blueprint that the animation blueprint then can use which is run on tick anyway.

[radiant bear]

this is from c++

i wanna compare this to a bp version hence i want to see the values before decimal even if it's 0

[dawn gazelle]

You're appending multiple floats which means you probably are seeing something like 35.6262.621677.7572

[radiant bear]

ohh i see!

[dawn gazelle]

Floats by default will always output at least one digit on either side of the decimal point 0.0

[radiant bear]

so the decimal is logged?

[dawn gazelle]

Yes

[radiant bear]

how can i give space between each other?

[lunar sleet]

Add a space

Another append pin in between with a space in it

[radiant bear]

got it

i don't think that added space?

[dawn gazelle]

Did you put a space in B and D?

Also that Make Literal String isn't required.

[radiant bear]

sorry mybad i thought it was a tick box

👌

[pulsar vigil]

tahts what i want to avoid im pretty sur u can update a variable without using an event tick in abp no ?

[lunar sleet]

You can, if you need to, but you don’t need to be afraid of tick either

[pulsar vigil]

yeah but that seem like an always win

[dawn gazelle]

It's usually best to let the animation blueprint do its thing on its own. Your actors shouldn't technically care about the animation blueprint, which means no force feeding it values, including events.
You could have the animation blueprint bind to an event dispatcher in your actor, then have it event driven, but it's not like you're saving performance doing so.

Animation BP must tick.

[pulsar vigil]

oh ok thx its look like it make it far easier, why does abp dont need those extra step when its better in any case apparently ?

[lunar sleet]

I may have read abp as “a BP “ 😅

[pulsar vigil]

im curious to know why it have to be on tick

to be fair i want to listen ur argument but the way i want to use the abp in my case is probably wtf

[radiant bear]

UKismetMathLibrary::SafeDivide(Speed, FMath::Clamp(GetCurveValue(FName("MoveData_Speed")), 50.f, 1000.0f))

could there be a delay from blueprint to C++?

[dawn gazelle]

It's not that it has to be, it's just that you're adding complexity by making something event driven and reading and setting a simple value on tick isn't performance hungry, since the animation blueprint has to tick anyway, there's no harm in it reading a value for its own use.
If you're doing some huge mathematical formula that you want to ensure is correct on an event and you don't want to have to keep recalculating that value every frame, then I could understand maybe wanting it event driven.

[lunar sleet]

Are you asking if blueprint is slower?

[radiant bear]

if cpp is slower

[lunar sleet]

No

[sick sky]

cpp is "slighlty" faster

[lunar sleet]

Bp is much slower, used to be about 10x slower

Now it’s a bit better tho I think

[sick sky]

cpp VS BP is the biggest asked question xD

[radiant bear]

the bp function fine but the cpp seem the get the values a few frames later

the curve values i mean

[lunar sleet]

Are you sending data from bp to cpp or what

[radiant bear]

no no

they are stant alone

[lunar sleet]

Ok

[radiant bear]

separate projects

[pulsar vigil]

its just an int justifying for changing an animation by pressing a button, in my case for sure its not a problem but i want to learn a good way to do so i dont saturate on tick thing like it seem to be a problem when thing scale

[radiant bear]

cpp

[lunar sleet]

I’d ask #cpp in case you missed something obvious, but also make sure there’s nothing slowing down that other project

[radiant bear]

bp

you can see the curve vale is a lot higher when when first value is 0ver 70

[radiant bear]

will try didn't get any answers for the past two days on #cpp

[radiant bear]

its speed, curve, then the devision

[lunar sleet]

I usually try to rephrase my question if I don’t get an answer, sometimes people will be like idk wtf that means and not respond

[radiant bear]

will try that now!

[south dagger]

I have to ask here, because im just not sure where else to post it I suppose. Im VERY NEW to programming in general, even tho ive dabbled in the past. Im really hyper focused on learning about blueprints as much as I can and surrounding stuff.
RECENTLY, I made a single Blueprint and made a pretty standard looking Archery Target for it. I gave the blueprint multiple blueprint components, in the hopes that id be able to use each component separately from the entire blueprint itself (IE 'Hit' Each individual ring and not the ENTIRE BP)
This is where im currently stuck and unsure how to target each component separately.

Im sure I can accomplish the same goal with multiple blueprints, but I would prefer to not do that if I dont HAVE TO

Im a stickler for clean looking blueprints

LOL

[lunar sleet]

For something like that I can understand

Just use separate collision shapes

Like capsules rotated on the side maybe

[dawn gazelle]

Here's a comparison...

Update on Blueprint Update Animation:

1. Set up animation blueprint to read value from actor on its tick.
2. Set an internal value in the anim blueprint (this is so it can utilize its separate animation thread)

vs. Event Dispatcher Method:

1. Mark your variable private so no other classes can modify it. (This is to ensure the event dispatcher is called so your anim BP updates)
2. Create an event dispatcher.
3. Set up your animation blueprint to bind to that event dispatcher on its init to then set the value internally.
4. Set an internal value in the anim blueprint when the event dispatcher is called.
5. Create a function on your actor to modify the value & call the event dispatcher.

This also ends up coupling the animation blueprint to that particular actor class.

[lunar sleet]

Then check hit on component rather than actor ^

[south dagger]

is that an option in the separate blueprint component itself?

[lunar sleet]

Yeah, you should see an override when selecting the component and scrolling all the way down in the details

Assuming we’re talking normal components not like actor component class

But maybe even then

[past compass]

is there any significant difference to "breaking vector" vs "split pin struct" ?

[south dagger]

I coulda had this done weeks ago, if this works, had I know this xD

[mental trellis]

I've heard split pin has some issues.

[dawn gazelle]

No, but be wary of using splits with custom blueprint structures.

[lunar sleet]

It depends on which break node

Ik you mentioned break vector but for nodes like hit traces, it’s better to break hit result than split the struct because it’ll let you collapse it once you’ve connected what you need

Doesn’t really apply if we’re just talking vectors tho 😅

[south dagger]

Being bad at this makes more questions than I know the answers to haha xD
even tho I ticked the box, I still dont know how to target just that component

[barren dove]

As a way around the issue for now, an easier way of doing this is probably doing an onoverlap event, then cast to the actor/component you're looking for, if the cast fails you cancel out with a branch, if it succeeds you continue on and do what you need to do 🙂 all you need is a capsule component on the offending component with the collision set to generate an overlap on the type of object that you want it to trigger

[south dagger]

As great of a work around this might seem, it doesnt really solve my base problem. Im trying to hit just the BP individual components. Adding more stuff to the BP wont help that and a separate BP defeats my original statement

I KNOW I can solve this with individual BPs, I DONT want to do that if I dont HAVE to

see where im getting at?

[barren dove]

yep, I'll try it out when I'm out of work but I'm pretty sure the process should be similar, I imagine yould cast to the actor and then the specific component but I'd have to try it

[south dagger]

let me know if you can figure that out! im not very good at this, but i have a feeling its VERY doable with the right know-how. otherwise... ick... multiple blueprints for 1 thing x.x

[barren dove]

oh for sure, I dont believe you can directly pull a component without first referencing the actor that was hit but I'll have to mess around a little to see

[earnest swan]

I'm new to using deligates in UE. I'm trying to fire an event when the class I'm 'subscribed to' fires its own event, but they're not firing even though the level manager is firing its own events.

[south dagger]

this was also something I figured

[dawn gazelle]

When you're saying blueprint components, you mean you're adding something like static meshes or the like... Here?

[south dagger]

exactly!

All in 1 bp

[barren dove]

if you slap a print screen between each of those components can you identify exactly where the chain stops and isn't firing?

[dawn gazelle]

If you right click on the component, you can get events for those components.

[south dagger]

O.O

I have some tests to do~

[barren dove]

oh I must have misunderstood I thought they wanted to put the event on the projectile and reference the thing hit not put a new event on each component :x

[south dagger]

honestly? I could probably use the knowledge for both

I wanna make some wacky stuff

[earnest swan]

I've ran print strings for the Level Manager's "Level Is Completed" event and "Start Level" event, so I know those are firing. I've checked the SetBellColourToRed and ResetBellColour, and both don't work with print strings

[barren dove]

hm, try and print out the reference to the level blueprint or actor or whatever it is and make sure its successfully "geting"?

[earnest swan]

yep, it's getting correctly

[south dagger]

You're my new unreal Saint! THANK YOU!!!!! HDRETGJRTHDEFGH

[lunar sleet]

This also works #blueprint message

[flat coral]

This feels like a stupid question, but I don't know the answer... if I've got a variable that's a blueprint type, like BulletDecalManager here, how do I open that BP for editing?

[lunar sleet]

Content browser

[flat coral]

I dont know where it is lol

[earnest swan]

you can search in the search bar

[lunar sleet]

Where you made it

[flat coral]

It seems crazy to type something out when it's already populated in editor

like, components you can right-click and jump to an edit window, that's all i'm looking for

[lunar sleet]

In some cases you can right click edit, but in this case you just gotta type a few letters

[earnest swan]

yeah

[lunar sleet]

It’s not really that big of an ask is it

[earnest swan]

it's good typing practice!

[flat coral]

Small in the grand scheme of things, but nonetheless bigger than it should be.

[lunar sleet]

Ctrl+space, select the content folder, start typing in search field

[barren dove]

I'm not sure why the event wouldn't be firing then, my only thought is maybe the change color on self isn't valid, but you've already dropped a print screen down there and it doesn't fire =/

[earnest swan]

yeah I'm confused as well... I must be misinterpreting what delegates are for because they just don't work for me

[lunar sleet]

Just don’t use level blueprint to begin with

Fixes most problems

[earnest swan]

it's not "the" level blueprint

it's a manager I made

which grabs information about a level I have stored, gives it to actors that need it and tells them to start

[lunar sleet]

Where’s the call, are you certain it’s firing?

[earnest swan]

yes, I'm certain it's firing because this starts the level

excuse my bad event names 😅

[lunar sleet]

I’m sorry I don’t see a Call anywhere

[earnest swan]

what do you mean then?

[trim matrix]

event event

[lunar sleet]

You’re binding events to a dispatcher

Where is the call

📞

📱

[earnest swan]

when you ask "where is the call" I'm not sure what you're exactly looking for 😅 I thought you meant "call" as "where is the event being called"

can you please clarify what you want to see?

[lunar sleet]

yeah, hang on, I need visual aids here

[earnest swan]

okie

[lunar sleet]

do you have that 2nd node anywhere?

[earnest swan]

is this what you're looking for then?

[lunar sleet]

no, that's just the bind

tell you what

go to blueprint communications pinned video here

watch it in full, yes it's like 2h

then you'll understand how it all works

dispatchers, interfaces, etc.

you'll prly need to rewatch some parts a few times tho 🙂

[trim matrix]

the host there tries to be entertaining so hard

[earnest swan]

oh...?

why is there two ways of calling the same event?

[trim matrix]

reminds me of that one microsft word tutorial

[lunar sleet]

you see the little envelope, that means message other blueprints

[south dagger]

Can you blame them? Dev videos arent always exactly the most.... entertaining.... xD

[lunar sleet]

He does a good job in this video tbh

[earnest swan]

ohh it works now! okay geez, I've learned something today

[south dagger]

noice!

[earnest swan]

envelope means it'll message others, gotcha

[lunar sleet]

you should still watch that video

[trim matrix]

they loose on quality if they try too hard to do that

[lunar sleet]

I didn't really understand casting until I did

[south dagger]

such a hard balance, it is

[lunar sleet]

even tho I told myself I understood it 😄

[earnest swan]

yeah I remember watching it a long time ago, clearly I need a refresher 😅

I like that guy

[lunar sleet]

I sometimes go back to it to refresh on interfaces

[lunar sleet]

idk, the profiling video host was very entertaining and yet so enlightening

[trim matrix]

man i'll never understand what to use the gm for smh

[lunar sleet]

Good place for Savegame functionality

[trim matrix]

🙂

[lunar sleet]

Others here will have better answers

[trim matrix]

would rather do it in the gi 🤔

[lunar sleet]

There’s this too, tho it’s mainly geared toward multiplayer functionality #multiplayer message
