blueprint

[dawn gazelle]

You don't. Input axes fire on tick. What you want instead is to make it an ActionMapping instead of an AxisMapping

[dawn topaz]

ohhh

i didnt know there was a difference thank you

[earnest tangle]

Mark your getters as const if they don't modify anything and it should work :) You can't const_cast in BP's so don't think there's any way around it

[dawn topaz]

also, what does this checkmark being on mean? there's no tooltip that tells me and google doesnt wanna say either

[dawn gazelle]

That means the boolean is set true.

[dawn topaz]

does it mean "this condition is tr--

oh

well there you go

thank you sorry again for the stupid questions

[trim matrix]

does anyone know how to make like regions in blueprints where u can name it

example

like this

[dawn topaz]

How would I "push" the player in a direction based on key input and with a predetermined (ie I set it manually) velocity? Impulse doesn't do anything, so I'm guessing that's not the right way to do it
I looked it up and I'm getting examples on how to automatically walk the player somewhere specific, which isn't what I want

I got it so it acknowledges a double tap, but idk how to do the actual moving part

[odd ember]

if you look at the templates they already show you how to do this with axis values

[dawn topaz]

(oh)
i am dumb, sorry
so I'd use Add Movement Input and stuff?

[odd ember]

not necessarily

I have no idea what exactly you're trying to do

but the input axis event

will have an input amount value that goes between -1..1

you can use that as a scale value on whatever it is you need to do

[dawn topaz]

but I'm using an InputAction to track the double taps... I'm not sure how I'd bring it back in

[odd ember]

I don't know what else you're doing

but if you want to walk forward

continuously

[earnest tangle]

if your player character uses a character movement component, apply impulse should do it

[odd ember]

you'll want to use an axis event

[earnest tangle]

the value may need to be fairly large tho

[odd ember]

I would not encourage the use of impulse or any physics based movement

unless you want unpredictability

[earnest tangle]

CMC impulses are not physics based

[odd ember]

PerformMovement handles the following:

Applies external physics, like impulses, forces, and gravity.

https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/Networking/CharacterMovementComponent/

[earnest tangle]

It's not physx based at least :P

[dawn topaz]

ummmm I'm not sure how to explain this but...
I'm using an InputAction node that checks for A or D
it checks if I hit A or D twice in a row, only once, or I just released it
when I tap twice, I want it to push the player a bit to the left or right (i realize rn i have nothing verifying which way it should make me go but thats okay)

i just dunno how to shove the player sideways really quick

[odd ember]

new location = get player character right vector * distance + player location

if you want leftside movement it's

get player character right vector * distance * -1

[dawn topaz]

...
another stupid question
how do i... put those down as nodes?
is it "Get Right Vector"? how do i get "Distance"?

[trim matrix]

Guys

[odd ember]

distance is a float value

[trim matrix]

What’s better

Ue4 or ue5?

[thin panther]

depends

[odd ember]

the secret ue7

[thin panther]

a lot of bugs in ue5 still

[trim matrix]

Hi @thin panther

[trim matrix]

Oh

[thin panther]

ue4 most stable, but if you neeeeeeeeed nanite and stuff then youll have to use ue5

[dawn topaz]

how do i access it through nodes? it's not this, right

[thin panther]

for learning nanite is unnecessary tho

[odd ember]

no it isn't. it's a value that you set

[trim matrix]

Nanite?

[odd ember]

何て

[trim matrix]

[thin panther]

pretty sweet auto LOD system

[trim matrix]

but again for learning that aint necessary

[trim matrix]

LOD?

Sorry I’m rly dum

[thin panther]

level of detail

[dawn topaz]

can you please show me? i dont understand...

[odd ember]

setup the logic that I showed you and you'll see automatically

[thin panther]

basically means you can set different decreasing complexities of mesh as you get further away

you ever played a game and noticed how the buildings look doo doo from really far away

thats LOD

[dawn topaz]

wait, but I straight up don't understand how to do that with nodes...!

[trim matrix]

How do I right in the different style here?

ALMOST

@thin panther

[thin panther]

thank you 🙏

[dawn topaz]

i still dont understand how to get the player's movement vector and add to the X value, please help

[odd ember]

what is that 👀

try with get actor right vector

and also

you can multiply a vector with a float

that's what yo uwant

[thin panther]

void imCool() {
  if(notcool) {
    delete(this);
  }

  else {
    cout << "I'm cool";
  }
}

[odd ember]

Lorash can you use escape characters in discord?

[thin panther]

yoo this is great

[dawn topaz]

I don't know, this is my first day using UE 😭

[odd ember]

look at what I wrote

I tried to escape ` inside ```

I'm not sure you can

magic

is it just ?

lmao

is it just \?

can you escape ` inside ``?

this

`does this escape \``

it does not

😔

[dawn topaz]

ummm I still don't understand, I'm sorry... won't multiplying the vector make them fly into space, since it's multiplying ALL of the XYZ values?

"get player character right vector * distance + player location"
i dont understand what to multiply or how to get the player location

[odd ember]

à``a

okay that works strangely

[odd ember]

get actor location is a node. what you want to multiply with is the distance you want it to go

UE uses unreal units, which are by default set to 1cm

[thin panther]

so the way vector work for movement is normalized, that means it has a length of 1, or how far you will move in that one length. If you multiply that by your speed you get how far to move for that many units you get me?

[dawn topaz]

😭 I still don't understand, I'm sorry
What, I multiply... whatever I am putting into the float part of the Vector * Float box by the player walking speed, and that equals...?

Where the player ends up?

[icy dragon]

check(bIsCool);

[thin panther]

return this.exists();

[dawn topaz]

I don't understand why I have to multiply and add just to go "player move 10 units to the right when i hit this key"

[thin panther]

because your right vector is 1 unit long

so if you multiply it by 10 you make 10 units long

cause 1 x 10 is 10

[icy dragon]

||ICYMI if check(bool) is false, the engine will crash with assertion failure error||

[dawn topaz]

so this wouldnt work?

[icy dragon]

Are you trying to teleport forward?

[dawn topaz]

(I don't understand what "World Direction" means either)

[thin panther]

exactly, in a state where i am not cool reality falls apart

[odd ember]

as opposed to relative direction

world is the direction the world is facing, like cardinal directions. north is always north no matter which way you are facing

[dawn topaz]

I just want the player to move right really fast a small distance when I hit a button

[odd ember]

but you can face north or any other direction

[icy dragon]

Also isn't Character Movement Controller already take care of this? Creating your own movement component isn't exactly advisable for beginners.

[thin panther]

||but i did miss it, but i wont admit that outside of /spoiler||

[odd ember]

it's not creating your own movement component lmao

[dawn topaz]

I'm trying to make a sidestep/quickstep mechanic :(

[trim matrix]

Ima go sleep it’s 1am lol

[thin panther]

uk too?

[trim matrix]

Like a side step dodge?

[trim matrix]

Yessir

[thin panther]

thought so

[dawn topaz]

yeah

basically

[trim matrix]

Fun

Too hard

Lol

[dawn topaz]

:(

[trim matrix]

Why’s that?

[icy dragon]

Oh, then I think Add Impulse might be what you're looking for

[trim matrix]

Too hard for me sorry I’m bad at phrasing things

[thin panther]

cause im 1am as well and i dont know any +0 time zones other than GMT

[trim matrix]

Ah ✅

Well gnight yall

[dawn topaz]

Nothing happened when I tried to attach an Add Impulse to the successful Double Tap output :(

[icy dragon]

Even trying with larger values?

[dawn topaz]

i just made it 100000 and nothing happened

i know its going through correctly because my debug message "2" is appearing

(2 being the number of taps it noticed in the timeframe it's given)

[odd ember]

anyway you were like 1 node away from doing it the other way

but good luck with the impulse stuff

[dawn topaz]

how do I do it then because I got stuck 😭

[odd ember]

I told you what to do if you read my messages

it's not rocket surgery

[dawn topaz]

but I don't understand what to plug in and type what and where!

[odd ember]

well you came pretty far without me telling you that either

you want the set actor location node at the end

everything will hook into that

[dawn topaz]

how do i make it affect only one axis? it warps me in all axises

[odd ember]

show your code

[dawn topaz]

actually I fixed it but I have another issue, how do I make it based on local (player) rotation and not world

because when i turn sideways and do it it throws me backward and not sideways still

[odd ember]

did you use the get actor right vector node?

[dawn topaz]

i dont know where to connect it

[odd ember]

go back and read my messages

[dawn topaz]

nothing is happening now regardless of the distance values i put in

[odd ember]

if you read my messages you'll also find which node to use at the end

it's like I've already given you all the answers

[thin panther]

that sounds dangerous

[gentle urchin]

Get right * float :)

[dawn topaz]

im a fucking dumbass

i had SetActorLocation in there before and then deleted it

have no idea if it works though

nothing's happening still

[thin panther]

(follow the solution given)

[dawn topaz]

doesnt work

[odd ember]

https://tenor.com/view/rickyism-tpb-gif-19857989

[odd ember]

can you show your code?

[dawn topaz]

i forgot to connect the "check for double tap" code to the actual movement section

please kill me

[thin panther]

https://tenor.com/view/face-palm-oh-no-oh-god-damnit-damn-gif-10780870

[thin panther]

in all seriousness

[dawn topaz]

why do i multiply the Get Actor Right Vector by a float value anyway
that still makes no sense to me

[thin panther]

weve all been there

[thin panther]

learn vector math and it makes sense

[odd ember]

right vector is a direction

[dawn topaz]

like it works but why

oough

[thin panther]

i explained ir several times

if you didnt read that its on you

[dawn topaz]

yeah and it didn't make sense 😔

[odd ember]

a direction in vector terms is a vector with a length of 1

so you multiply it

and you get a length in that direction

[thin panther]

.

[dawn topaz]

I just don't understand why X=55 or whatever has a length of 1

it says 55

[gentle urchin]

Its not 55

Its 1

If its perfect right

[dawn topaz]

going to have to go to khan academy for this 😔

[odd ember]

the right vector is like saying "right of yourself"

[thin panther]

this is why math and gamedev are two peas in a pod

[gentle urchin]

If facing perfect forward (alongnworld X axi your forward vector is (1,0,0) and your right vector is (0,1,0) , up is (0,0,1)

[dawn topaz]

I was never good at math, which is why I'm more of an art person when it comes to game dev 😔

[thin panther]

can always learn math

[odd ember]

now's the time to brush up on math

https://tenor.com/view/quick-maths-mans-not-hot-gif-11163522

[thin panther]

computers are just complex calculators

if your tryina program em you need the math

[odd ember]

everything can be abstracted to a number, or a sequence of numbers

[dawn topaz]

OH WAIT

i think it just clicked in my tiny little skull
you multiply the right vector so it changes the value that you yeet over to
and then it's added to the location to properly apply it to the player

[odd ember]

yeet over to

the youth of today

[dawn topaz]

idk how to phrase it

[odd ember]

lmao

[thin panther]

everything is numbers, thats why char x = 97 results in a

in fact, you are probably numbers

we are all numbers and thats ok

[odd ember]

yeah it's correct, otherwise you'd yeet from the position of 0,0,0

[dawn topaz]

i guess i shouldve said "moved" but i may or may not be smoking out of the top of my head

[odd ember]

we have accepted that yeet is now the correct term for this

[thin panther]

who is the official dictionary person

[dawn topaz]

yeet: (verb) to move along a vector

[odd ember]

now to get it accepted in academic papers

[thin panther]

can we get moved changed to yeet

[dawn topaz]

i will write them an angry letter telling them to change it

[thin panther]

whats the past tense tho

if i moved along a vector

did i yote along it?

[dawn topaz]

yes

yote

[thin panther]

ight

[odd ember]

yote or yoted?

[dawn topaz]

its like threw and throw

yote and yeet

[odd ember]

Hey everyone, I am total beginner still and currently trying to implement a shooting mechanism. The idea is to shoot multiple bullets and then wait x time. So I would need multiple delays but as I discovered that will not work as the delays will be ignored. Any idea how I could solve this?

[short pawn]

You could do a branch with a variable that is set to a number when you start shooting and have the variable count down to zero with a timer and when it is zero not be able to shoot

[blazing scroll]

but I want a delay between each shot. I am little bit confused how to do this with a counter

[short pawn]

Branch with boolean then set boolean to off. Make that incrementally subtracting integer set to 3. Then make a delay that then sets the boolean back to yes

With a timer

[blazing scroll]

Since I want to constantly shoot bullets shall I attach it to event tick?

[odd ember]

if you disable event tick when not in use

sure

[blazing scroll]

So that is what I currently have but that does not trigger the delay in the loop

[odd ember]

delay on tick does nothing

you'll have to disable tick

[short pawn]

Why not just make a timer on begin play instead of tick

[blazing scroll]

I tried it with a timer as well but I could not make it work either

But if the tick is disabled it will not Loop right?

Because I want it to excute constantly

I'm having kind of a weird issue, I'm trying to implement a custom movement mode in BP, and I want the character to slide while it's active, but when I enable custom movement and use OnMovementModeChanged in order to enable physics and gravity on my player capsule so it can slide, the UpdateCustomMovement just... stops being called. If I remove the 'Set Simulate Physics' node it goes back to getting called again.

Does simulating physics on a capsule stop the movement component from working or something? I want to be able to continuously check for stuff while sliding, and I'd rather not put it on tick, so I figured I'd let physics handle most of the movement but still be able to use the custommovement for logic.

[odd ember]

you want to execute constantly, except when you delay right? so disable tick, delay, enable tick

Thank you!

[radiant mural]

Then, you can check if shift is down by checking the true/false of the bool variable bIsShiftDown

[unreal quail]

is it normal that when the game is paused I don't get input anymore?

the true branch is never called

[round moth]

oh nice i see

[radiant mural]

I have never used Pause yet, so no idea. Please let us know when you figure it out

[unreal quail]

well it seems it's not the pause that causes issues, I just removed everything about it and the second keypress still never gets registered

[radiant mural]

Maybe try the same bool approach i showed above, instead of calling the function which i do not know exactly what it does (you might)

[unreal quail]

yeah that's what I did and as I said it doesn't help as my input is still not getting taken into consideration by my player controller

[radiant mural]

maybe try a Print String when your Pause key is pressed and just test the function of the press itself

[unreal quail]

it was because I used Set input mode UI only

[radiant mural]

That, of course, was not visible on the BP you posted

[unreal quail]

ah actually it wasn't

I had already tried fixing it by removing the set input mode UI only

that alone doesn't fix things because it seems like input doesn't get propagated to the player controller when the game is paused

[radiant mural]

I think this is your answer https://forums.unrealengine.com/t/i-can-pause-my-game-but-how-can-i-get-it-to-unpause/284036

I have it doing a branch that if stamina is less than 1, basically empty, then to go to the base run speed. but it doesnt work at all.

[unreal quail]

Cool deal

[dawn gazelle]

Input events like that only fire a single time.

It doesn't constantly check to see if your player is out of stamina.

So now your stamina drain is framerate dependent. If someone gets 30fps, they'll only drain 15 stamina in 1 second. If they're running 60 fps, they drain 30.

[round moth]

I am pretty happy with myself today. I changed the camera distance on my third person character, coded a ladder, coded some really sketchy wallrunning, made world triggers. put a hat on my robot lady, made double jump with effects

oh ok

i dont want that

how do i fix

[dawn gazelle]

And your stamina will drain even if they're not moving.

[round moth]

no

it goes up

only drains if i hold shift

[dawn gazelle]

If you press shift, the stamina will drain while standing still.

[round moth]

oh i see

good point

Hey all, was wondering how difficult in general terms it would be to create a "perpetual save" in blueprints, in one's opinion?

[twin oxide]

i see

but how comes that the making process is different ?

i mean

there is no canva panel

i just added one, seems to fix my issue

but why isn't there one by default ?

[solemn bramble]

If you rigth click in the Content Browser and then attempt to create a widget BP, User Widget type should be default

Bottom of the context menu

[twin oxide]

yes it does

[radiant mural]

Sometimes widgets are just a button that is called in to another widget. In that case, i do not think you would use the Canvas Panel, but instead,just let the button be the whole thing.

[twin oxide]

but i'm just a bit surprised that there is no ca

oh

makez sens

makes sense, thank you both 🙂

[solemn bramble]

Yes, canvas isnt mandatory

It usually is for huds and menus

[twin oxide]

I was just used to it being there by default in 4.27 if im not mistakin

[solemn bramble]

But isnt for 3d widgets for example

[radiant mural]

4.26 or 4.27, i think so

[solemn bramble]

Health bars

[twin oxide]

i see

[solemn bramble]

Glad it helped :)

hello all, i didn't understand how disabled to all client arrow 1, arrow 2 not working

[hollow rune]

Howdy all, I'm currently trying to make a profile system for my game. I'm attempting to get these profiles to save and load from local files, but the main issue I'm coming across is that I'm generating the available profiles in a scrollbox, and displaying the information in a widget switcher beside it. But I can't figure out how to get the profiles, which act as buttons, to affect the widget switcher.

I'm still new to all of this so I hope you folks can help 🙂 (Just occurred to me that this might belong in the UMG section as well, it's just here because I'm doing the programming in Blueprints)

[trim matrix]

anyone know why setting keyboard focus only works after using a delay node? I can switch up the order to set the keyboard focus first, but if i lose focus and then try to put it back, it won't work unless there's some sort of delay before calling it.. It's really strange

[radiant mural]

@round moth Hey, I am about half way through this sprint/stamina tutorial. I can honestly say it is the most relevant, and well done one i have found. https://www.youtube.com/watch?v=Lu8FpIEqVzg 'Moonrider'

[radiant mural]

SpringArm is already a Component of my CharacterBP. If i drag it out to the Event Graph and make twenty wires come from one, or if i drag it out twenty times because i do not like spaghetti, does it make any difference? Is it faster to only have one with a bunch of wires, or does it not matter because it is already a component and not a 'cast to' or a 'get player controller' etc.

[halcyon nova]

hey homies - anybody got any idea how to set the airborne linear velocity damping on a first person character?

I expected it to be in the movement component - hard to tell what actually has simulated physics

[earnest tangle]

character movement component has all the settings that govern the movement of characters by default

if it isn't there then it doesn't exist and you'll have to implement it yourself

[half portal]

YOYO GUYS! I'm using this for starting the game from main menu, however the game input stops working properly if I release left click, if I hold it I can move around freely, once I release the left click it doesn't let me to click to move again (TopDownTemplate)

I tried the Game and UI input but that breaks the functionality of the on click movement in a way that if held the cursor position cannot be adjusted

[hasty river]

Hey, does someone can explain me how the property access system works in anim bp ?

Can't find any documentation.

[half portal]

https://www.youtube.com/watch?v=NRwMmHNs0KU have you watched the anim bp series from unreal?

[hasty river]

I'm talking about this new property access system showed in UE5

[radiant mural]

I am not sure what exact problem you are having, but to get mine to function properly, i had to make sure to Unset 'Use Pawn Control Rotation' after switching game modes

[half portal]

Oh I see, could you clarify it a bit, how can I unset it, much appreciated~!!!!

[half portal]

Alrighty let me try!

[radiant mural]

But you may have a completely different issue than i had.. "that if held the cursor position cannot be adjusted" This is not super clear

Are you aware of this?

[half portal]

Once Im in the topdown map and game mode, if I hold on ground to move, it doesnt let me adjust its position, cursor is stuck

[half portal]

Haven't tried this one, tried the Game and UI

Will give it a go now

[radiant mural]

Ok, also, make sure than when in topdown mode you are in game and ui mode, not game mode

[half portal]

Using this doesnt let me move the character

Tried this and when mouse was held it wouldnt let me adjust its position

[radiant mural]

Why are you hiding mouse cursor during capture?

[half portal]

Switched it to show, but doesn't make the difference

[radiant mural]

set to 'game and ui' mode After you load in to the level?

[half portal]

Trying it now

Thx for your help

[radiant mural]

Np, hope it was actually help 🙂

[half portal]

Did I done goofed, should this be on begin play of the level instead?

[radiant mural]

Well, while testing, i would bind it and 'game only' mode to keys so you can toggle everything until you figure out what,why,when,where

[half portal]

Ohh Interesting, will try that

[radiant mural]

even show/hide mouse cursor.. put it on a key bind

[half portal]

I see

Thing is that it works properly if its launched on its own and not from the menu

Which to be indicated that issue is in the mainmenu bp

[maiden wadi]

OpenLevel doesn't actually process anything until next frame. So the order of that won't matter.

[radiant mural]

Good to know, thx

[half portal]

I FIXED IT

SHOUT OUT TO @radiant mural for support

Had to untick "hide cursor during capture" and all seems smooth sailing now

[radiant mural]

Cool deal! Have fun 🙂

[trim matrix]

Guys

Does anyone know how to make something infinitely spawning?

Like for a runner game

[half portal]

What exactly haha

[half portal]

Search UE spawner on YT for tutorials, not sure what you need but there's plenty content on that out there

[trim matrix]

Ok Ty

Ping me if you need anything

[spark steppe]

@trim matrix i need love

also, you may want to move some stuff with the camera instead of respawning it

[trim matrix]

❤️

[spark steppe]

a man, a word. thanks 😄

[trim matrix]

?

[spark steppe]

if it's a siderunner

[trim matrix]

Yh

But I do t understand the first msg

[trim matrix]

This one

[spark steppe]

like the background, or ground, can sometimes be moved with the camera/character instead of spawning it over and over again

unless its supposed to change

[trim matrix]

Oh

[ruby ice]

I'm stumped with an issue spawning AIFrom Class ever since making a copy of my project from UE4 to UE5. Picture 1 is the blueprint of the spawning mechanic: generates a point inside NavMesh with a print string to indicate if there is no valid location found. If successful, a debug point is drawn and then the Spawn AIFrom Class is attempted. The debug point always spawns, but no AI spawns. This is the same blueprint from UE4 and nothing has changed so I'm not sure what has happened between versions? Unless I'm just missing something obvious? Pic 2 shows the NavMesh, it's just a flat bit of land for testing. I've tried changing the spawn collision method to "Always Spawn, Ignore Collisions" and that had no effect. I also made a simple trigger box with a hit event to test the spawn and that works fine, so I'm a tad lost 😅

[maiden wadi]

The NotValid prints?

[ruby ice]

Just another attempt to see what was having issues, seems to be the Spawning but there might be something else I'm missing

[maiden wadi]

Does NotValid or Valid print?

[ruby ice]

NotValid, so nothing is spawned at all

[maiden wadi]

And that's even with NoCollisionFail on?

[ruby ice]

Damn it, there was just something basic I missed 😂 Cheers @maiden wadi , I don't suppose there's any reason why this happened between UE4 and UE5 that you would be aware of? I know initially I had issues with my landscape texture being blank, only to find out that the texture node LayerBlend exists but since fixed it

[maiden wadi]

I'm not sure. I don't think the spawning code for that has changed from 4 to 5. I just glanced through it. Only three things can stop the AI pawn from being created, and that's an invalid world, invalid pawn class, and collision errors if that is unchecked.

[ruby ice]

Very strange, but I'm very thankful that's things are back up and running 😄

[gusty cypress]

I'm trying to create a function that checks whether the current level is "map2" and if it does it will turn the product of "axis value" and "amount of torque" to negative. It doesn't seem to be working... Any help?

[honest fable]

Anyone else notice that when you Show the Mouse cursor, and then while playing drag left and right (So turn the camera), that the game becomes really laggy?

Mouse dragging the camera makes my game jitter a lot. Not the same when I turn mouse visiblity off

To recreate this:

Create a new third person example project, add a custom player controller to your game. Inside tha controller go to defaults settings, set 'Show Mouse Cursor' to true. Then start dragging the game camera left and right while playing (Look left and right), if you turn the cam kinda quick the character becomes jittery.

This does not occur when you dont drag the viewport with the 'Set show mouse cursor = true'

[tight schooner]

Return node disconnected? Otherwise try normal debugging stuff like breakpoints and prints

[charred berry]

How would I go about un greying physics > simulate phsyics , for my rope BP ? I've looked everywhere and on forums, no idea, no replies, its the only thing left for rope to work as expected.

[fallen abyss]

I have never seen this node before, how can I get it?

[tight schooner]

Looks like material node graph... Try #graphics

[dark crow]

It's just a MF Input

That's a Vector2

Called UV Scales

[fallen abyss]

I am rather new to ue4 so what exactly would Ihave to type in the search bar? @dark crow

[dark crow]

Are you in a Material Function?

[fallen abyss]

I am here 😆

[dark crow]

Yeah no, you can't do that unless you are in a MF

[fallen abyss]

this one?

[dark crow]

It won't work

You can't think as a MF as a repeatable code that can be used in different material graphs

You can define shader logic in there and have different inputs based on the MF Inputs

Like a normal Function with Inputs

So what you're really searching for in that case for the material graph is a Vector2

You can get one by keeping 2 pressed and left cliking

[fallen abyss]

I am trying to recreate this

Maybe that will help to clear things up

[fallen abyss]

I am by no means a programmer (I am an artist)

[dark crow]

Then you gotta create a MF

You can right click in the Content Browser -> Materials & Textures -> Material Function

[fallen abyss]

ahhhhhh!

That is where the MF is XD

[dark crow]

Then here you can assign it from the drop down

Where it says None

[fallen abyss]

Awesome

This might be a stupid question, but what happens in that particular MF?

it says vector 2?

so do I just add an vector 2 in that MF

[dark crow]

It's an input so you will provide it from the actual Material

But yeah, you will provide a Vector2

It's UVs

So X and Y

[fallen abyss]

I am gonna give it a try, thank you for the support

[trim matrix]

Hey can i somehow reverse a bool

Like input true and out put false

[dark crow]

Not

There's a node called Not

[trim matrix]

[stuck trench]

QUESTION:
How to check if video (MediaPlayer) has reached the end?

[dark crow]

Delegate

OnEndReached

[stuck trench]

I'm trying, but it doesn't work

[dark crow]

Show

[stuck trench]

Whenever I try to pin create event to it and "create matching event" it comes with an error. But when I try to pin function instead of event it works. But I don't want to use function

[dark crow]

Delegates work with functions tho

or Events

Try a custom event in case

From the Event pin

[stuck trench]

I haven't work with Delegate before

[dark crow]

You gotta bind to an Event / Function for what code to run when OnEndReached is called

[still rampart]

is there a way to pause a timeline?

[dark crow]

Lemme see if i can find a picture online for that Delegate

[stuck trench]

Would you please help me in voice call?

[dark crow]

This should work ^

For the Delegate setup

[stuck trench]

I cannot add custom event

[dark crow]

Complains about signature?

You have to create it from Event to match the signature iirc

Drag from Bind Event

[dawn gazelle]

Probably trying to do it from within a function.

[dark crow]

That would be an issue too :D

Aka show pics!

[stuck trench]

like how do I create event without using this "Create Event" node?

[dark crow]

Are you in a Function?

[stuck trench]

yes

[dark crow]

Then that's the only way

You can't have Custom Events in a Function

[stuck trench]

but it doesn't work with the create event node

[dark crow]

I'm not even entirely sure binds work in a function in the first place

Since when it Returns, that's it

[stuck trench]

So should I do it out of function?

[dark crow]

Yeah, at max you can make it a Macro

¯_(ツ)_/¯

[willow cedar]

Random question about Event Dispatchers, but what purpose do they serve? I've been using Cast To nodes, along with Interfaces for most my code now, and stopped using Dispatchers ages ago. Is there a reason or use case for them?

[dark crow]

I mostly use them for UI stuff and global Events

Stuff that I want my actors to listen for

[willow cedar]

Even with UI stuff though, you already get a Widget reference to any events in it

[stuck trench]

I need to do something after video (media player) reaches the end @willow cedar

[dark crow]

You can create a Button Widget with custom presets and styles for example and you can Delegate the OnClicked

Widget won't have the OnClicked out of the box only because it has a Button inside it

[willow cedar]

Hm, Never ran into that so I guess I'm not sure what that is adding onto functionality wise.

[dark crow]

And Imagine if I have a global event like a thunderstorm and want something to happen on certain actors

I could loop through everyone and see if they implement an interface which sounds inefficient

Or just have the actors interested in the event listen for it

[stuck trench]

So what should I do?

[dark crow]

I think of it as a radio station broadcasting something and the ones tuned in will receive the message

[dark crow]

Just take it out of the function, the entire thing

[stuck trench]

ok

[dawn gazelle]

Or leave it in the function and use the "create event" node.

[dark crow]

He said it doesn't work for some reason, lol

[odd ember]

people really need to stop using interfaces for this in BP

[dark crow]

Yeah

[stuck trench]

it doesn't work

[dark crow]

Probs cause you have nothing selected as an Event

Function i mean

[stuck trench]

wait I will show you...

[dark crow]

But am puzzled here cause

When a function returns, doesn't it just end for good?

Will the bind even work at that point?

[stuck trench]

signature error

[odd ember]

right click on the create event node > refresh

ah

[dark crow]

I imagine so cause it's related to the variable

But still

[odd ember]

then use the create event node to create a new event

signature means that you don't have the parameters set correctly on your event

[dark crow]

Probs renamed CustomEvent_0 to VideoReachedEndEvent

So doesn't recognize it anymore

[odd ember]

nah

if it's signature it means the parameters need to be there

[stuck trench]

still the same

[odd ember]

in that node

click the drop down > create new event

[stuck trench]

that's what am I doing all the time bro 😆

[odd ember]

is this a custom delegate that you have made?

what happens if you take the red wire down to the event node directly instead?

[stuck trench]

from "Create Event" node or from bind event

[dark crow]

Works on my side

[stuck trench]

But you don't have it in function

[odd ember]

bind event to test

let's say

[dark crow]

Omg CE

Unreal

It creates a Custom Event inside the Function

LOL

[odd ember]

lmao

well then

cut and paste the node into the event graph

and you should be gucci

[dark crow]

It has no particular signature parameter wise too so even just creating a normal Custom Event and Assigning it should work

But totally take it outside the Function

[odd ember]

yeah generally if it does have a signature, I'd always suggest generating a node through the CreateEvent node

much less error prone

[dark crow]

For sure

[stuck trench]

is it ok now?

[odd ember]

is it inside the function?

[stuck trench]

no, otherwise it would have errors

[odd ember]

you can still have the bind event inside the function, just not the event node itself

[stuck trench]

Ok, but I think there is no need for me to add this into function graph. I don't know why I tried to make all this inside function...

[odd ember]

no worries

[stuck trench]

Thank you very much 🙏 @odd ember @dark crow

[willow cedar]

Is there a way to get the center of a collision component on overlap? All I can think of is Actor Location, and that returns the vector of the actor and not the collision sphere vector.

I just solved my own question not even 2 seconds into asking it lmfao. You use Other Comp output from Begin Overlap, and just get World Location

[trim matrix]

Does anyone know why it is so hard lagging ingame ?

[stuck trench]

@odd ember Now I know why I wanted it in function. I cannot have it in normal graph, it doesn't work outside of function

[stuck trench]

I will try this answer from you 🔼

@odd ember how can I bind event inside the function and use the event node outside? it's not possible?

[trim matrix]

Anyone know why this would make the head tilt in opposite to tilt of camera ??

I bassically am wanting where the camera looks the head of player looks

I'm also getting this error as well which I can't think why

[odd ember]

create event node

[stuck trench]

inside or outside the function?

[odd ember]

inside

[trim matrix]

How do I get rig of this stupid thing it constantly comes up with anoyes hell out of me

[stuck trench]

But there is this kind of error we had before

The Error? CustomEvent01 or something like that

[odd ember]

not if you place the event node itself outside of it

the event node has to be outside

the create event node can be inside

dig?

[stuck trench]

so should I choose in Signature: "Create a matching event"

ok now what

cut the "VideoFinishes" event outside of the function graph?

@odd ember ?

[icy dragon]

Why not pass the square pin from VideoFinishes to the Bind Event node?

[stuck trench]

Erm

I don't think it's the right path @icy dragon 🙂

[icy dragon]

What's the error saying?

[icy dragon]

Does it occur with any new custom events?

Empty custom events shouldn't throw that error when bound to another event AFAIK

[stuck trench]

I should let you know that everything here is inside function

[dawn gazelle]

You can't have events in a function.

[stuck trench]

How can I do that then?

[dawn gazelle]

You can still use the event, put it in an event graph.

Then use the "Create Event" node in the bind, and select the event.

Make sure you hit compile too if you're getting errors.

[stuck trench]

@dawn gazelle how?

You want me to go to Event graph and create new event like I did in the function graph?

[willow cedar]

Is there a way to pick a different channel instead of just Visibility and Camera?

[stuck trench]

OMG, I'm so dumb...

I hope I understand everything now... Thanks a lot brother 🙏

[dawn gazelle]

You'd need to create additional trace channels in your collision settings within project settings.

[willow cedar]

Ah, Okay. Thanks

[stuck trench]

@dawn gazelle Do you know how to set video playback to the beginning (time 0:00) and play the video? Is it using the "Seek" node and "Play" node afterwardsF?

[dawn gazelle]

Sorry, not really familiar with the mediaplayer itself.

[stuck trench]

No problem, I'll play around with that and hopefully get it work

[willow cedar]

What would be the most efficient way to calculate location of closest Overlap component? Need this to update as long as there is something being overlapped.

[odd ember]

any time you receive a new overlapping component

or well

if you need it per frame you can't get around per frame calculations

[mild kestrel]

Does anyone know how can I Do stuff AFTER every Animation Update but BEFORE rendering?

Is there specified tick group for that?

[willow cedar]

Yeah, the issue is the character can move between these two overlapping components, and they might move too, so the distance can change

[odd ember]

so you probably need to rethink this approach wholesale if you need more efficiency

[willow cedar]

I guess I don't need efficiency, I'm just curious if there is a better method than what I'm doing.

This takes care of it, and runs on a timer event at .01. I'd like it to invalidate the timer if the amount of overlapping components is 0

[odd ember]

timer at anything less than delta time is useless

might as well set it to delta time

[willow cedar]

Oh?

Out of curiosity, why is that?

[odd ember]

because timers aren't truly frame independent

[willow cedar]

Ah

That's what I thought

[odd ember]

they will loop multiple times per frame if you set the time lower than delta time

but

they will only ever update on the next frame

so you get all of the calculations but none of the results

[gentle urchin]

I wonder, does a timer average out over time, with overflow of time since last exec?

[willow cedar]

Where should I get Delta Time from?

[odd ember]

I'm not sure what you mean

[odd ember]

delta seconds

as in, the green node

[gentle urchin]

Lets say you set 0.034 (delta) as the timer value

And the frame delta is 0.038

Does it then carry over 0.004?

[odd ember]

carry over doesn't make sense

the timer runs independently

it updates per delta time

so the calculations run

but the result only gets updated whenever the frame updates

so 34 ms, (frame update), 34 ms, (frame update), 34 ms, (frame update) etc. until at some point it runs 34 ms, 34 ms, (frame update)

at which point it updates twice on that frame

[willow cedar]

What's the best way to track blueprint code performance?

[odd ember]

FPS

if your FPS is fine

you're gucci

[willow cedar]

lmao, true. I guess I would like to learn what nodes are more costly than others

[odd ember]

it doesn't matter

code efficiency only matters if you have problems

and you won't know what code will give you problems

even expensive code is fine if it's not called often

[gentle urchin]

And doesnt cause framedrops at important times*

Like in a fight

[flat mauve]

Hey guys! I have a question. Who knows how to create code that can generate a human skeleton within a static humanoid mesh? Is this possible? Thanks

[odd ember]

is it possible? probably

is it possible in BP? unlikely

[flat mauve]

I see

Any idea on how to achieve it in c++?

Any leads?

[odd ember]

do you even know how skeletons work

[flat mauve]

Yeah

Skeletal meshes is what I'm talking about

[odd ember]

so you understand that they have a rig

so you understand you'd have to build that rig

it's not really even a thing you'd do in engine really, it's something you'd want to handle in your DCC of choice

and I'm sure there are tools or plugins that exist for that

[willow cedar]

Would any of you have any useful Unreal Plugins that you'd say add some quality of life features to Blueprint or the Engine in general?

[odd ember]

nah I'm pretty vanilla

[flat mauve]

yes exactly. I'm trying to achieve this with through God to create an automation feature

through code sorry hehe

But God also works 🙂

[odd ember]

well you'd have a better chance of executing it through god 😂

really I'd look for plugins for your DCC

[flat mauve]

hahaha!!

[odd ember]

it's going to be much harder to build it in engine

[flat mauve]

DCC? What's that? Sorry for the noob question.

[odd ember]

digital content creator

your 3d package

like maya

or max

or blender

[flat mauve]

Oh i see

[odd ember]

those are the tools equipped to handle these kinds of things

[flat mauve]

Yes i know it's possible through those. This is a new feature i'm trying to develop. It's not about doing the rig. It's about the feature

[odd ember]

and to be clear, even if you do end up being able to automate a lot of it, the generation of them will likely be buggy and will require a bunch of manual work

you might be able to do something through control rig, but that's #animation

certainly in BP it's not possible

[flat mauve]

Yeah. Blueprints may be a tough one. But thought maybe someone here may have had a C++ solution

[odd ember]

you're barking up the wrong tree

[flat mauve]

I cast my nets wide 😄

[odd ember]

the channel is #blueprint

if you want cpp you'll find that there's a channel for that too

[flat mauve]

Okay no prob. Thought it may have been possible through blueprints though. No harm trying 🙂

[icy dragon]

Rama's Victory Plugin

Some were very low level.

[hasty river]

Hey, doesn anyone know why I can't play anim montage inside an Object bp ?

[icy dragon]

What's Weapon Instance class inherits from?

[odd ember]

because an object has no relation to the world

[hasty river]

So I need an actor instead of object ?

[icy dragon]

Yes

[hasty river]

Ok, thanks

[cobalt gulch]

Hi this is a long one.

Basically I started coding in a starter project but the character has a few issues, the camera doesn't line up with where the player is looking, and I would like to use the code in a different character with the unreal engine 4 animations from the marketplace

How could I do this?

Would I need to replace the animations?

I'm willing to stream my project if it helps

[thin panther]

FWIW auto riggers can be quite messy, and youll need ti weight paint it anyway. Its worth just using an auto rigger for blender then fixing the weight painting

Theres a reason rigging is its own job title

[open latch]

How can I make an Indian Jones type of trap?

A pressure plate that is linked to spear in the wall.
I am thinking of having a collision box on the group once triggered to sets a boolean to true which fires off the spear.

But how do I set of that specific trap without setting off the spear traps.

[thin panther]

you would store an actor reference in the pressure pad

click the eye so its public

then use set that to be the spear you wanna activate in editor

then you just call the activate on your pressure pad when needs be

[undone surge]

whats the diff between get relative location and get absolute location

[mental trellis]

Relative is relative to its parent

[odd ember]

same as local/world

absolute is world position

[undone surge]

so like if i want to get the location of my char in the map i do absolute right

[mental trellis]

Yes.

[radiant mural]

How come if i change the name of the ReturnValue the stamina bar stops responding to changes in stamina? (I cannot find where the name of that variable matters)

It is just a binding within the Widget

[maiden wadi]

Why does it matter what the return parameter is named?

Most likely it's a problem with the binding code. The added UPARAM may break it.

[radiant mural]

The name of it is less important than why to me

Ok, thank you

[maiden wadi]

To rename a return variable in C++ at least, you have to mark it a UPARAM if memory serves.

[radiant mural]

Checking the c++ code of Progress Bar

[maiden wadi]

As far as general advice, I would avoid UMG bindings like a plague. Literally using EventTick is better. Bindings can be broken when set manually from anywhere else.

The one and only real useful UMG binding is the TooltipWidget

[radiant mural]

Ok, I will see if that works with what i am doing. Thanks

[undone surge]

im trying to despawn an emmiter after picking up a mesh based object , if i destroy it before the emmiter then the emmiter stays forever bcuz the actor destroyed but if i do it after then the pickup mesh also stays till the emitter is destroyed

[odd ember]

you can't do stuff like this

nothing should ever go after "destroy actor"

on self

[undone surge]

hmmm

[odd ember]

why not set the particles to auto destroy

[undone surge]

they play for a v long time

can i edit their play time ?

[odd ember]

are you asking me for permission?

[undone surge]

no xD

like

in the niagra thing

is there a way to edit

[odd ember]

I'm sure you can answer that question yourself

or if not, there is always #niagara

[undone surge]

ok thanks ill try it

[Help] Hey everyone, I'm on a project that's for some job training kinda stuff.. I need to recreate like a ratchet strap and I'm not exactly sure what to use for the strap.. a spline mesh with physics on it? orr... idk.. I don't have any 3D modelling experience so I know I won't be using a skeletal mesh with animations

[odd ember]

what's a ratchet strap

and what kind of job training requires you to do stuff outside of your experience level

[faint pasture]

Also, "Have you tried?" works as well.

[jaunty jolt]

isnt this supposed to create a loop everytime i press H ?

So if i press H 10 times, it should start printing Hello 10x per second ?

[thin panther]

I mean that would print once a second theoretically

But thats a terrible way to do it

[jaunty jolt]

it is printing once per second. but i press it again, it doesnt print twice per second.

[thin panther]

No thats not how that works

You just retrigger it

It doesnt dublicate the code

If you wanna do stuff with time, look up the proper ways. You are probably looking for a timer

Set the timer to loop

[jaunty jolt]

this is causing a problem because i have a big function that moves many rabits around. And sometimes i need two groups of rabbits to move around. So basically i need to use the same function twice. In c++ this would call the function separetely. But in blueprints it just retriggers, right?

[thin panther]

You havent made a function

But anyway

What your doing seems incredibly complex for bp

Mass unit movement systems are prime c++ territory

hi, i don't know how can i do it: i have timeline and i want change camera rotation, i get current camera rotation and i don't know how connect it :/ someone can help?

or Timeline + FInterp?

some suggestions?

[tight schooner]

The BP approach to needing two instances of code running simultaneously would be to spawn two objects. You have some rabbit group manager actor spawned for each group. Or maybe they could be components added dynamically to a host manager actor.

[tight pollen]

I need a smooth transition from the current camera rotation to other

without using an event tick

[jaunty jolt]

i see now, thank you.

[thin panther]

Why no event tick

What tou are describing is tick based behaviour

(And a timeline is a fancier event tick)

You cannot smoothly transition between things without doing it frame by frame

Its impossible

[tight pollen]

yea

but i mean doesn't use Event Tick

only Timeline + FInterp

[thin panther]

Again why

[tight pollen]

something like this

[thin panther]

Why do you need those soecific nodes

Interp to is commonly paired with event tick

[tight pollen]

I saw someone on YT linking Finterp to Timeline somewhere, but i can't find it

[tight schooner]

If tick, then use InterpTo nodes. If timeline, save start & end locations to variables and then use a float timeline to drive the alpha value on an interpolate node.

[thin panther]

^

Still unsure of the ovidance of tick

Tick is not bad

A lot of people think it is

But it aint

[tight schooner]

Yeah, in this case, ticking is appropriate

[thin panther]

In fact its probably cheaper than a timeline

Cause a timeline will have a bunch if wrapper code

If computers can calculate all this amazing lighting at runtime

They can do a camera on tick

Hey guys I'm creating a tower defense game and in terms of upgrades, would anybody have suggestions for how I make the towers on this plate be able to be individually selected,

The tower currently functions as click it, and spawn actor above it through widget

Is there perhaps some way to link them if you don't mind my asking?

[faint pasture]

Protip, anything smooth (updates per frame) is using tick somewhere. Usually the answer is to use tick if it needs to happen all the time, or timelines for short sequences.

That's what tick is. It is the event that happens every frame. If the thing updates or happens every frame, it is being triggered by a tick somewhere

[tight pollen]

Yes, I know, but why use Tick all the time, how can you use it once within e.g. 3 seconds and turn it off after these three seconds

[thin panther]

well then ye timeline is good, but its just a cause of establishing tick aint bad, as a lot of new people seem to think that

sorry for misinterpreting :)

you wanna use a lerp it seems

lerp between two rotation variables

with the alpha being based off a timeline

[tight pollen]

yea, that was lerp in that video on YT 🤦‍♂️

thanks

[thin panther]

no problem

[faint pasture]

That sounds like a timeline

[thin panther]

(the timeline should go from 0 to 1 btw)

[tight pollen]

yes

[thin panther]

turn it into a curve if you want it nice acceleration and deceleration

[tight pollen]

thanks

[thin panther]

no problem

[still rampart]

ive got a child actor that disappears when i hit play. any idea what might be causing this?

nowhere in script im i calling for it to disappear / destroy self

prelaunch

on play

placing the child actors independently (no parent) they do not disappear.

[tight pollen]

why this doesn't work

in timeline is from 0 to 1

if i add print string after update and look at this rotation

can see that it is changing

but in game nothing happen

camera have still same rotation

[thin panther]

your camera is likely using your control rotation instead

try adding control rotation instead of setting the actor rotation

setting*

[gritty elm]

I want to get 5 random index from array. but index should be unique ( not same )

[thin panther]

pick index, if it is the same as one gotten pcik again

[faint pasture]

Shuffle array

Then get first five items

[gritty elm]

Yes this is what I already thinking. Thanks!

Anyone have any idea why this isn't working? It should return the value of 100/110 as a percentage and update the healthbar. But it doesn't.

[faint pasture]

First of all why isn't character Max health a variable on the character?

[summer jetty]

It will be. I'm just trying to get the basics to work first.

Either way, the value of 'Health' should be 100.

[faint pasture]

@summer jetty that function needs to return a value. Read your errors

[summer jetty]

I don't understand the error. It should return a value.

[faint pasture]

Just return that float

[faint pasture]

You have no return. You are using a function as if it was just an event. Don't update the percentage yourself, that's a binding. It's just asking for you to set up how it should calculate its percentage

[summer jetty]

Doesn't it need the max health too? Otherwise, how does it know what the Health value is a percentage of?

100 out of 'what'?

[faint pasture]

Yes, that function should return the float. You shouldn't be updating the bar inside the function. That's the whole point of a binding.

It either expects you to return a float in the range of 0 to 1 or 0 to 100, I'm not sure. But right now you are returning nothing and just setting the widget parameter.

[summer jetty]

ok, I had the percentage in a separate function and the value stored in another variable (which I plugged into it) but that didn't work either. Hence me trying it this way.

[faint pasture]

Your shit is all fucked up. Have MaxHP and CurrentHP in the same place (pawn or GameInstance like you have now), and in this function, just return CurrentHP/MaxHP

[summer jetty]

ok, I'll experiement with it

[faint pasture]

Your formula for calculating maxhp from level should not live inside a widget, it should be handled wherever level and hp live (Pawn, Playerstate, Gameinstance, wherever)

BTW you'll want another return for the case where the cast to YourGameInstance fails, just return a 0 or whatever.

[summer jetty]

ok

How should I go about doing variables for attachments on weapons? I have so many weapons that everything would be too much to put in one place

For example saving what attachments a player has

[faint pasture]

What attachments they own or what attachments are on each gun class?
