[surreal peak]

If it's just Singleplayer, then you aren't bound to UE4's GameFramework as much as you'd be with Multiplayer

Which is good and easier of course

And the question is to save the current game slot?

[summer jetty]

Are there any tutorials/examples you know of that show how that works?

[surreal peak]

No idea

It should be enough if you understand how the SaveGames work

Your UI would create a slot per SaveGame and clicking on one UI element should allow you to save the SaveGame Slot Name

Save as in either put into GameInstance for the duration of the Game process, or even into some secondary SaveGame for the users profile (if that' wanted)

[summer jetty]

It would definitely be stored in the save game as the data needs to exist for that slot when the player logs out/back in again and picks that slot to continue playing. It’s just the temporary game instance stuff I’m struggling to get my head around.

[surreal peak]

But we are talking about the Name of the Slot that was taken for the specific session

Not about any actual savegame data

Each of your 3 SaveGame slots has a Name. May it be SaveGame_1 to SaveGame_3

When you start your game, you probably have some UI with 3 Widgets

[summer jetty]

Yep

[surreal peak]

Where each Widget counts for one of the SaveGames

When you press the WIdget, you know which SaveGame got selected

SaveGame_1, 2, 3

[summer jetty]

3 buttons

[surreal peak]

Take that name and save it on the GameInstance

And whenever you load or save data, you use that variable from the GameInstance

[summer jetty]

How?

[surreal peak]

"How?" is too vague of a questin

Which step is the problem?

Calling "GetGameInstance->CastToYourGameInstance->SetActiveSaveGameSlot(...)"?

[summer jetty]

How do I store that selected name on the game instance?

[surreal peak]

Okay, do you have the SaveGame Name at hand when you press the button?

So when OnClicked is called for example

I assume so

[summer jetty]

Yeah

[surreal peak]

Right, do you have your own GameInstance Blueprint?

[summer jetty]

Yes

[surreal peak]

In that Blueprint, you should create a variable, call it "ActiveSaveGameSlot" or so

I think it needs to be a String

[trim matrix]

yes

[summer jetty]

Ok I did that

[surreal peak]

When you press the button and the OnClicked is triggered, call "GetGameInstance", cast it to your own GameInstance BP Class, and set the new variable with the Name

[summer jetty]

(got to this point before)

That’s when I was getting errors. I’m travelling atm, but it was complaining it wasn’t referencing something if I remember correctly

[surreal peak]

Shouldn't happen if you use the GetGameInstance node

This is a globally available reference (pointer)

Just don't make a custom GameInstance pointer

Cause that is invalid until filled of course

If it does happen, you'll need to share screenshots of your code

[summer jetty]

Hmm... ok ‘ll have another play around with this when I get home. Thank you both for your help. Sorry for the noob question! 😁

[surreal peak]

Once you accomplished this, you should be able to use that ActiveSaveGameSlot variable whenever you load and save

[summer jetty]

Ok I’ll give it another go

[surreal peak]

Until the game process is quit and restarted, then the player would need to select a savegame again

[summer jetty]

Yep

[surreal peak]

Oki

hi guys, does the buoyancy feature in 4.26 require to have a water volume to work ?

[tired chasm]

Hey guys. I got a question about swimming with a third person character. I'm trying to add vertical movement while in the water by pressing the Left or Right trigger buttons on a controller. I thought it would be super easy to do but I'm having a few problems.

This is what I have for my BP for the vertical movement and with this, the character always rotates towards the same direction when the button is pressed (North I think?)

I just want the character to move up or down. I don't want any rotation. I also trying using "Add Impulse" but that doesn't work right either.

[maiden wadi]

@tired chasm You can likely ditch half of that and just use the world's UpVector. Or a MakeVector with 0,0,1. But nothing there will affect rotation unless your character orients to velocity or whatever like that.

[tired chasm]

oooh alright I'll try that

[soft basin]

Hey sorry for asking such a dumb question but I'm really struggling with such a basic problem. I have a bunch of AI driven characters running around killing each other and would like to add a kill feed. I can manually add a child to a UI widget through a key press with code in my level BP so I know the UI works. Where I get stuck is triggering an even in the character BP and passing through the variables for the killer/victim etc. The characters have an ondamage event that makes them check if they have 0 health and then handles the death sequence if necessary. I assume this would be the right kind of place to grab my variables and pass them to the UI but I can't figure out how. Should I be using the gamemode BP or another actor, or possibly a BP interface? I'm really only just getting started on this so I'm unaware of the common methods for handling this kind of thing. Thanks for any help anyone can offer with this!

[tired chasm]

oh yeah I think since I have this ticked it's giving me problems with trying to move up and down... but I do need that ticked and would like my character to rotate in the direction the player is moving the stick, but going up and down also seems to be affecting the rotation ><

[trim matrix]

short answer: i handle it that when i spawn the characters, they get spawned by the gamemode and it binds an event listener to it. If you place the actors via level editor, you could bind the events in the BeginPlay of the GameMode which then does "getAllActorsOfClass" (or what it is called) and binds to the death event for each of those

Pressed on play but the game didn't start

[trim matrix]

please show more code 😉

[soft basin]

Thanks man! I shall look into event listeners! 👍

[uneven geode]

hi, somebody worked with recieving 360º livestream in unreal?

[shrewd condor]

Guys, I have a strange issue, I am setting collision enabled to Query Only on one blueprint, but each time I restart the editor it is set back to collision enabled (Query and Physics). I am sure that I saved it and it is checked out from perforce.

[chrome fractal]

Cast shadow Isn't working in blueprint for a single static mesh how can I do this please help

[hearty lintel]

guys i need to do some cubic interpolation through BP, does anyone know how i can achieve it?

I got an actor wich has an array of locations and i need to interpolate them in a smooth way like that.
Keep in mind that Vinterp and vinterp constant don't do the job. I need the cubic interpolation 🙂

Thank you!

[calm schooner]

Construction BP to randomly rotate a mesh around the X axis if the user has RandomRotation=true in the editor.

When the BP first runs, the mesh's original rotation is stored in the variable Original Rotation.

When the user ticks RandomRotation=true, the object snaps to a random rotation within the Rotation Amount as expected.

When the user ticks RandomRotation=False, the pipe does not set back to it's Original Rotation as expected.

Do I just need to put this in the Event Graph so it will update after placed instead of the construction script, or is something else going wrong here?

Yep, it looks like that's the solution, but why is this? Why doesn't the script behave as expected when it's on construction rather than on Event BeginPlay?

[chrome fractal]

please help

[trim matrix]

your variables are not initialized (empty pointer as you might say). it seems that you have variables defined in the blueprint actor, but they get not filled with references

you also should go from the "find sessions" failure exec to Set "finding sessions : false"

[graceful forum]

So, I checked the ENetRole enum and it's not declared as BlueprintType, hence I get that there is no switch node. But if that's the case how I can select or create a member variable of it?

[hearty lintel]

yeah that's what i thought as well! shall i use the "add math function" node for that right?

thank you really much 🙂

[quasi frost]

Does anyone know anything about projectile movement? Why doesn't this move towards my player which is the child of the parent playable character?

[spice shore]

for some reason i cant get the ai to contuie moving after a level is loaded via the menu blueprint, however i can makie the ai move if i open the level directly

[boreal ether]

{
    return FMath::CubicInterp(P0, T0, P1, T1, Alpha);

}

[hearty lintel]

thank you really much man! I guess this one is c++ right? is there a way i can have a node in the blueprint so i can work with it? i have no experience in c++ unfoprtunately yet

[boreal ether]

It's c++ to add a BP node. Look up how to make a blueprintFunctionLibrary and then add that to the .cpp file

[hearty lintel]

ohh okay awesome thanks!!!

[boreal ether]

        static FVector CubicInterp(FVector P0, FVector T0, FVector P1, FVector T1,float Alpha); ```

This goes in the .h file

No worries 👍

[hearty lintel]

🙂 thanks a lot!

[boreal ether]

Let me know if you can't get it working

[hearty lintel]

i will have to download the source version of the engine first i guess

[boreal ether]

Yeah I guess if you want to avoid c++ you'd have to implement the math yourself. But I'd recommend just getting started with c++. You'll need it for something eventually

[hearty lintel]

yeah absolutely true, at some point it will be needed lol, im a 3d artist tho ahah

[boreal ether]

Well here's the code if you want to implement it in blueprint ``` /**
* Performs a cubic interpolation
*
* @param P - end points
* @param T - tangent directions at end points
* @param Alpha - distance along spline
*
* @return Interpolated value
*/
template< class T, class U >
static FORCEINLINE_DEBUGGABLE T CubicInterp( const T& P0, const T& T0, const T& P1, const T& T1, const U& A )
{
const float A2 = A * A;
const float A3 = A2 * A;

    return (T)(((2*A3)-(3*A2)+1) * P0) + ((A3-(2*A2)+A) * T0) + ((A3-A2) * T1) + (((-2*A3)+(3*A2)) * P1);
}

[hearty lintel]

thank you so much man!

[spice shore]

hey @boreal ether can i grab your help?

[boreal ether]

Not sure what the issue with that could be tbh. What does the movement code look like?

[spice shore]

its player movement, its the ai pathfinding movement involing navmesh

for some reason if i open the level using menu blueprint widget it does not move, meanwhile if i open the level via the viewport it works fine

[boreal ether]

Do you get any errors in the log? Try typing "show navigation" in console to see if the navmesh is built?

[spice shore]

the navmesh is built and there is no errors

[boreal ether]

Try a breakpoint or print string in your AI movement code to check if it's being called?

[spice shore]

@boreal etherThe ai blueprint doesnt appear to activate, is there anyway to activate it?

[boreal ether]

How are you testing that it doesn't activate?

[spice shore]

print strings

apparently i had to restart my pc to get it to work, might have been a bug or something

[little flame]

hi guys! im just about to finnish a project in UE4 for the quest, but cant wrap my head around the very last thing. I have a BP spawning an actor but everytime it does that it crashes. did somebody experience smth similar? when its connected to the pc its fine

im destroying the actor after each spawn so it cant be due to extreme amount of meshes etc.

[boreal ether]

have you checked the log? And logcat output

adb logcat -s UE4 -s debug -s DEBUG

[little flame]

how do I do that when its only on my headset?

it doesnt happen in the editor

only when i disconnect it from the computer

[boreal ether]

Connect the headset to your computer and go to UE4Game/yourGameName/saved/logs or something like that

And run the adb command in a command prompt or powershell

[little flame]

@boreal ether thanks joost, but I just made the most simle trial ever basically eventbeginplay hooked up to spawnactor as the only BP in the scene and it crashes...

must be a bug? or the quest cant handle spawpning?

[boreal ether]

You can definitely spawn actors on the Quest. It doesn't crash if you don't spawn anything? I'd strongly recommend checking the log and logcat. There's probably an explanation for the crash in there.

[little flame]

no it works fine as soon as I remove the spawning bp

it seems it cant spawn actorclass BP

[zealous moth]

wanna show us your spawning logic?

[quartz flax]

Hi. I'm struggling a bit with figuring out how to work with data table category handle. Having a hard time finding good documentation/examples on it. In the below example, I'm obviously getting all the rows of the table, and not just the ones I want by category handle. I want to get an array of RowNames for the rows matching my CategoryHandle. Can someone give me pointers on where to start? https://puu.sh/HV3S3/225c3c86cf.png

[glad mist]

Hello everyone, I'm making grid based WASD movement (Using Timelines and VLerps), I'm trying to get the movement to be smooth when I hold a key down, but there's a weird jitter. Anyone able to help?

https://gyazo.com/37784feded5d988d259caa7022720a47

[jaunty solstice]

Anyone know how you might expose the Skylight’s Source Cubemap Angle so that it can be dynamically changed in runtime or in the Sequencer?

[onyx token]

is it possible to change these using blueprints?

like change the padding on the Bottom?

[burnt nest]

Yes.

[onyx token]

ok, in that case i just screwed up and i gotta look into it more...

because i tried this

but that just gave me error messages

[tight schooner]

Does the jitter happen on frames where one timeline ends & another begins? If so, I wouldn't know how to go about fixing that short of making your own on-event-tick movement math thing

[burnt nest]

Why on earth would you increase the padding by 1 every frame? 😱

[burnt canyon]

Mad man that's why

[onyx token]

just so shit moves and i can see it
What i actually wanna do is control my skyrim-esk inventory using WASD

like when i press W - the list scrolls up by whatever the amount of padding it is, until it gets to the next item

[burnt canyon]

So you want to navigate the menu using wasd

[onyx token]

yea

[burnt canyon]

So I believe there is controller support by fedault for this

I am slightly unsure about wasd

However

I assume your not disabling the mouse?

[burnt nest]

Right. Well. The error first of all I believe is because you're trying to treat the Vertical Box as a Vertical Box slot. It has slots, but it isn't a slot. Hence you get a "accessed none" error.

[glad mist]

yeah, it happens when one ends and another begins. I think Event Tick might be the way to go for this one too :p

[onyx token]

well what i wanna do is this
https://cdn.discordapp.com/attachments/847253861403197471/863095128138448926/SrEu8m3Kfy.mp4 @burnt canyon

[burnt canyon]

You prob want a uniform grid

[onyx token]

ooh i see

[burnt canyon]

With just one collum

[onyx token]

hmmm and then switch between grids using A and D ?

[burnt canyon]

Wait

Do u want the list to move up and down

Like in Skyrim

[onyx token]

yea

[burnt canyon]

I misread some

Right okayy

[onyx token]

that's why i was trying out with the padding

[burnt canyon]

U know

I think it's just a case of changing the selected unit

And using anim

To move the box

UmG anim

Maybe

[onyx token]

can animations stack?

because idk how many items i will have, so it might have to move up or down unlimited times

[burnt canyon]

U can move anything in Umg

[onyx token]

that's why i thought working with a padding float i can just lerp would work neatly

[burnt canyon]

Not sure if it will look proper with changing selection tho

UMG has huge animation system built in

For moving stuff

Or maybe u can move units in a scroll box

[onyx token]

why must stuff always be huge and complicated

[burnt canyon]

So many options ahhh

[onyx token]

so if i wanted just for the sake of checking if it may work - to go ahead with the padding thing before i dive into a giant umg animation system-

How would i go around "Slot as Vertical Box Slot"?

because this way doesn't work

[burnt nest]

Since Luna's being a champ, you're good, but for future reference, #umg is where you're most likely to find widget experts 🙂

Well you gotta make a new node

[onyx token]

oh lol i didn't see #umg sry about that 😅

[burnt nest]

And you need to add the padding to one of the elements contained in the vertical box, rather than to the vertical box itself, otherwise it's the padding around the entire box you'd affect

[onyx token]

i wanna affect that tho

[burnt nest]

It's fine, this is blueprint too, just that people in #umg are likely going to have the best answers 🙂

Oh well alrighty then 😛

So if you drag out from it and search for set padding, do you get any results?

[onyx token]

https://cdn.discordapp.com/attachments/847253861403197471/863097682385698857/UAqfREDigm.mp4
Yeah but only this

[burnt nest]

Turn on context sensitive 🙂

[onyx token]

oh lol

well in that case it's empty x_x

[burnt nest]

Okay let me boot up UE and I'll have a look

[onyx token]

thanks alot

[quartz plume]

Hi! I have a problem. I have this kind of hierarchy on my blueprint class. All platforms have the same ability (rotating and falling the water). What should I do to not copy myself in code? I think about actor child but it's very not elegant and it's not recommended (I read). I think about something like prefab, but is it on UE?

[onyx token]

use blueprint actors?

[quartz plume]

Hm what do you mean?

[icy dragon]

Why not just split them into 3 actors, and make use of Event Dispatchers?

[quartz plume]

Yeah, but How can attach it in one owner actor?

By child actor?

[onyx token]

aren't there actor instances you could use?

[icy dragon]

It really depends on what game design you're trying to achieve tbh

I still don't have any visual imagination of your written puzzle mechanic description.

[quartz plume]

Top platform get some water, when it fill with water, then it invoke next platform. If it is on correct position it again, fill and repeat the procedure for the last platform

🙂

Of course I want to use Event Dispatcher, but as you can see, many of this components are rotating

[onyx token]

okay so i can scroll my entire widget...
So if i would make a new widget, that's only the list of items...
And place it above my background widget...

could work right?

or is that scuffed?

because then i could just move the item-list widget around, making it "scroll"

and keep the background where it is

[white field]

I want to take an arbitrary float and convert it to 1, what is the math term for this?

[onyx token]

absolute

[white field]

hmm

say I want to counter a scaling value higher up in a component tree

the root is scaled to .75 1.5 1 or whatever

break the vector to floats but then the value needs to be the proportional offset of 1..

absolute is for zero isn't it?

like the corresponding desired value for 1.5 is .6667

.75*x=1 etc

[tight schooner]

"abs" removes negative signs, ensuring the output is positive (-2 becomes 2)

are you thinking of "normalize vector"?

takes a vector and makes the length of it 1

[burnt nest]

crap. I totally forgot about UE while it was starting up. sorry about that 👀

[onyx token]

don't worry

i'm trying out the widget position moving

[burnt nest]

nice 🥳

[white field]

yeah perfect, ty

was drawing a terminology blank

[fluid compass]

hey im wondering why the bullets ive created wont collide with the shield i am using to block it

im thinking it might be the thickness thats the issue

the BP ^

the collision settings ^

[burnt canyon]

heads up, afaik for actor tags

there odly and kinda rusty/broken

would not recommend using unless they have been patched up in the past year

[maiden wadi]

@fluid compassBullet actor component hierarchy?

[fluid compass]

how broken, as in it just doesn't work at all?

i'm using 4.24

[fleet cedar]

Trying to scale down the Advanced Vehicle blueprint but it breaks when I do... is this avoidable in any way or it's all built with measurements and physics that don't scale

[meager wasp]

hi, quick question is there a way to connect a int to a text render component

so it displays the int value in the text

nvm its set text, i got the wrong one...

[fluid compass]

yeah theres a conversion to text or string node

[meager wasp]

Im not sure why its rendering like this if soemone can explain why its like this and is there a different way to approach this without using a HUD

I cant take a good picture, the text is flickering and is barely visible, like its a totally different thin font

I cant get a ss of the text when its selected, but its barely visible. its showing, just not as it should be

Had to take it w the phone

[vivid bane]

Hello , does anyone know how to get local or relative location of an object on tick ? What i get now is just the static value of last position but wont update on tick like the world location or rotation :/

[red trail]

Not sure why but I am on the Unreal SenseiAcademy and I cannot figure out why Keyboard 1 & 2 do not work as shown in the example of this course it the 8th video titled "Inheritance - Parents and Children at 4:57-6:06 my 2 types of blocks do not spawn or anything but it shows in real time that it is firing the keyboard buttons so I am not sure what the issue is. I am taking a screenshot of my code

I think I posted this in the wrong discord server

[maiden wadi]

@red trail Print the newly spawned actor's location. And change Collision Handling Override to Always Spawn Ignore Collisions.

[red trail]

I'll try that

[sand bloom]

hmm i'm wondering what i'm doing wrong here, I have an event.

[red trail]

it didn't work

[sand bloom]

I see the event firing a string but input is not enabled

[maiden wadi]

@red trailWhat's it printing?

[red trail]

oh wait when you say print you mean put like a print string? to test it?

[sand bloom]

Is get player controller not good enough or am I using the wrong target? I want to use the right mouse button in this actor so leaving it to self is good right?

[maiden wadi]

Yep. See what the newly spawned actor's location is.

[red trail]

oh that part I need to do one second

[maiden wadi]

@sand bloom Have you enabled MouseOver events in your custom controller class?

[red trail]

so like this?

[sand bloom]

oh no I didn't even know I had to do that

[maiden wadi]

Yep. MouseOver is disabled by default usually since Unreal defaults to FPS gameplay.

[sand bloom]

oh wait

I did enable that

way earlier

[maiden wadi]

@red trail That maybe too. But after the SpawnActor. Drag from the blue pin and GetActorLocation and print that as well after the spawn node.

[sand bloom]

so that couldn't have been it sadly

[maiden wadi]

Are you actually getting execution from the mouse over? Could be a collision issue as well.

[sand bloom]

It fires the proper string every time a collision starts and ends with the mouse

hence my confusion

Not sure what could be going wrong really

[red trail]

nope

[sand bloom]

Could it be because i'm trying to use a input on a pawn? While already controlling another simple camera pawn?

[maiden wadi]

@sand bloom Curious. If you change that to a keyboard input instead of a mouse, does it work?

[sand bloom]

ill check for you

sadly no

[maiden wadi]

@red trailDo you see either of those prints?

[red trail]

nope

usually what I do is I start over on the blueprints believe it or not run the whole thing again to do it right

[maiden wadi]

@sand bloom Odd. To be fair, I've never tried that on a Pawn with enabling input. Theoretically it should work unless they're maybe AI possessed, then their Controller may interrupt that. To be fair, I tend to avoid mouse overs most time. Much easier just to project mouse location to screen space and rely on line traces in my opinion.

@red trailIf you're not seeing any name, then your 1 or 2 isn't setting your value. Or something else is nulling the class after 1 or 2 is pressed for some reason.

[red trail]

okay I"ll check the code again for something else in a bit taking a break

[sand bloom]

hmm yeah ill try with setting it to playercontroller instead of ai controller

doesn't work so far but ill try fiddling with it

[trim matrix]

This the widget blueprint

[sand bloom]

Yeah I just don't know it's not the mouse's fault since the string fires

the input just refuses to do anything..

I guess I need to use a actor this sucks I wanted a pawn to use move to location

[faint pasture]

Pawns are actors

[sand bloom]

I mean I guess that's on me

Yes you're right

But I meant I have to use an actor that isn't a pawn and see if that works

hey it works

so I guess the issue was it being a pawn

so that does suck but atleast I can move on now I guess

[trim matrix]

Guys

[sand bloom]

will just have to try a more tedious method instead of move to location

[trim matrix]

i press on play using my widget interface but nothing happnes

[icy dragon]

Show your BP or no one can help.

[vivid bane]

Does anyone know how to get local or relative location and rotation on tick ? :/

[trim matrix]

Scroll up

[icy dragon]

Or just repost the screenshot.

[trim matrix]

this

[timid rune]

Does anyone know how to make this so that it saves a new index each time it is run, instead of changing the same variable?

[dim harbor]

Hey, can someone help me please? I created an Event Dispatcher on a Widget and now i need to create a Reference to that Widget (to bind and Event to the Event Dispatcher) on another Blueprint. How can i create such reference?

[timid rune]

Unless it is the level blueprint, you can cast to the widget and call a function.

[icy dragon]

Can you load another level with it?

[candid blade]

any idea why this wouldn't work?

intensity is at 0, and on the level bp i'm trying to raise the value with a timeline

[faint pasture]

Is the point light static, stationary, or movable?

@candid blade do that with the timeline, not using the tick event chain

Timelines "tick"

[dim harbor]

Thank you @timid rune , but i cannot cast to a widget becasue i have no reference to it. How can i get a reference to the widget?

[candid blade]

so you're saying i should control the intensity with the timeline on the light bp rather than the level bp?

[timid rune]

@dim harborNot sure if this helps but this is what I do.

[faint pasture]

Well depends on how you want to do it, and you didn't say before that you have many lights that have to be driven by one time line. Either way, the timeline update can directly change the value, you don't need to use ticks on the lights

[dim harbor]

Yes, that works well, Thank you @timid rune .

[candid blade]

@faint pasture thanks for the help, I ended up calling it with a bp interface and doing the timeline on the light bp itself

for those interested:

[timid rune]

No Problem

[celest pagoda]

How do i access animation montage notifier ? in blueprints

[sand bloom]

Hmm so I got a lerp that follows my mouse pointer each tick for smooth movement, it works well enough but how would I go about adding a jump with setworldlocation happening each tick?

I tried various things

Like adding a separate lerp and timeline just for the jump

but I can't really get it to work

at best i can make it teleport somewhere which is not what I want

[faint pasture]

You're gonna have to explain more about what you mean by jump

[sand bloom]

Imagine a cube on the floor, that's supposed to "jump" go smoothly to a location upwards the z axis and then as gravity kicks in it falls

i'm starting to consider an entirely different way of doing this

instead of set world location with lerp

because of the jump

[dawn warren]

Any hint or guide/tutorial on how to create a multiplayer character customization? Im working with a dedicated server,

[sand bloom]

But I figured i'd ask if anyone knows a way because I do like the left right movement I got going on right now

it's a sidescroller kind of thing btw

so not fully 3d movement

y axis is locked

I could do a similar thing with add impulse and big collisionboxes to the side of the cube I guess

[faint pasture]

@sand bloom So what's that got to do with the mouse following? What is your control scheme

[onyx token]

quick question - how was lerp done again if i want it to last 1 second?

not like this afaik

[faint pasture]

Just timeline it.

[onyx token]

but lerp is so smol and neat tho

[sand bloom]

It follows your mouse whenever you right clicked a actor it adds a check saying follow my mouse slowly basically

and you would use your left click to make it jump

wherever it is

[faint pasture]

yeah but it doesn't do what you want it to do

@sand bloom Are you using any movement component or just hard coding the movement like this?

[sand bloom]

but it seems like a bad way to do it I guess, right now i'm trying to add impact left or right depending if your mouse is touching either of these red zones, but I can't make the mouse recognise them for some reason

[sand bloom]

hard coding with physics enabled

[faint pasture]

If you're using physics just term everything into forces and impulses

[sand bloom]

yeah that's what I'm trying to do right now

[faint pasture]

Ok so use a vertical impulse for a jump

[sand bloom]

I guess i should have done it from the start

now ironically it's reversed

I can't get left right to work

because my mouse is not registering these two boxes, oh they are just not moving lol, ah man i am wasting so much time on dumb shit, finally got it work. Can't believe I tried all this convoluted nonsense first, nvm it's now broken again because attaching them to the cube so they move along with the character breaks the ability for the mouse to notice the boxes

[green eagle]

Welcome to the job

[sand bloom]

haha yes

[stoic coral]

Is there any good modular way to clone 3d objects multiple times, like the cloner in c4d?

[green eagle]

So I have a curiosity. When we do something like "attach actor to component" or similar type situation. That actor always seems to have some reference to where it originally started at in world space.
So this means that no matter what you do with the object the data for all its starting params is still saved.

Anyone know if there is any functionality that clears post data? Or a way to like "clear prev references" ?

[green eagle]

You can make tools with blueprints like using splines and creating custom params.
Or
Use a third party software like Houdini or anything with a built in API that would allow you to create a tool and use it in UE that way.

[stoic coral]

Thanks, I'm wondering what kind of nodes would create instances of a mesh

Or just clone it

[green eagle]

do it in construction script. have static mesh components. use add instance. and so on and so forth.

@stoic coral

[stoic coral]

Amazing, thanks a lot

Also is it possible to animate the parameters of the nodes in the sequencer?

[sonic silo]

I have a point in my map (lets say 0,0,0).

And I want to know if the camera is at the right side of the point or at the left side.

How can I do this. Which nodes should I use?

[green eagle]

Do you mean right/left of the player/raytrace?
Not sure if you are trying to find vector data or just trying to figure out which side of the actor the camera is on.

If you are wanting design like "if player has object on there left side camera jumps right" and vice versa using vector data and some simple collision solution might work well at least to experiment.
But like Lorash said.
@sonic silo

[sonic silo]

Right/left side of camera

Or lets say screen

At left or right side

[strange pike]

im remaking my hit detect system and need help differentiating between a few nodes: whats the difference between point and radial damage?

[green eagle]

When setting "physics constraints"..

When player picks up actor > carries it around > drops actor at new location

It teleports the actor to worldspawn location when I turn "physics constraints" on. No idea how to get it to update those constraint locations.

Thanks in advanced and before you ask. The "DetachFromActor node" is set properly it drops where ever i drop it when im not trying constraints out.

[meager wasp]

not sure where to ask, is there a way to add a button or 2 buttons to show up above a actor, after its been selected.
ex.
Event Actor On Clicked -> show 2 buttons(2 options). selecting one of them shows some text component and the other is a action, that ive not done yet. Not sure if this can only be done with a HUD or is there a different way of doint it.

[green eagle]

experiment with HUD/Widget

[meager wasp]

can I activate the HUD with from a blueprint? Ive never done that so im asking

[strange pike]

as in widget visiblity?

[green eagle]

yep pretty common question and lots quick tutorials on it.

[meager wasp]

yeah

widget not shown, clicked on actor -> show widget

pretty much the plan

[strange pike]

make your hud inside the actor

[meager wasp]

hud from actor and not a new widget?

[strange pike]

join the unreal hangout voice channel. ill explain what i mean

[tawdry bone]

Is it possible to make a material that highlights the wireframe but also renders the faces?

[green eagle]

expirement with render states and visibility settings. You can target object/area values and determine what is hidden/loaded.
Might be better to ask in Materials to get some ideas on the PBR side of things.

[burnt nest]

basically sounds like low poly style

[tawdry bone]

Sort of trying to emulate old vector graphics

[burnt nest]

then just google low poly style graphics for unreal, should be pretty common

[tawdry bone]

Low poly is different than vector graphics

[green eagle]

seems like a good area to google too

[tawdry bone]

Vector graphics means something different in modern times, those are scalable vector graphics, or svg

[tired chasm]

you trying to go for something like a SNES Star Fox?

[tawdry bone]

I'm sort of looking for something tron-esque

[tawdry bone]

this is the type of vector graphics I'm talking about

[tired chasm]

Ahh I see. hmm

[green eagle]

Yeah putting retro in the search came across more of that type thing as i said it sounds like materials is where the question would find more of an answer type your liking.
The first page of results seemed to me hit the nail on the head but if your google results arent helping ya.. idk man.. id show ya some tricks but thats a lot of time when dont even seem to sure of what ya want. sorry

[pine trellis]

im confused, if I add spehre collusion to my mesh, how come it doesnt show up in the game, its like there is no collision there?

shouldnt the collision be round?

[green eagle]

Like i dont get it.. does "tron graphics in ue4" search results work for what you are looking for?

[green eagle]

or maybe wire frame?

[tawdry bone]

I was able to make a wireframe shader, so if you'll look back to my original question, I wanted a way to highlight the wireframe while also rendering the faces

[tired chasm]

Yeah the only thing I found is this https://www.youtube.com/watch?v=KHiZfy5OlO8 but idle if that would show the faces the way you want. The best thing I can think of is just making a texture to do what you want and an emission texture that highlights all the edges, but I'm sure someone smarter than me can come up with something better.

Maybe you can have what's shown in that video to show over the top using masks.

[tawdry bone]

Thanks for the help I'll look into it!

[next trench]

Can anyone help with this issue i am having? Basically im making an inventory system and when i try to open the inventory it crashes. Here are the logs

[maiden wadi]

Your array has nothing in it and you're trying to access index 0. Index 0 doesn't exist.

[frail marlin]

Are you able to reference actors in a stream level if it is loaded, but not visible?

[dim harbor]

Hey can someone help me? I need to know if can set up blueprint communications between a Widget and an AIController. For what i know, it is not possible, but i am not sure.

[zealous moth]

@@dim harbor You could but i am not sure why... ai controllers dont do much but follow ai commands. Did you mean ai pawns? Change their vars and therefore their behavior trees?

[runic parrot]

Hi! does anyone remember what is the component to render a scene on a widget?
i want to create a window showing the view of some other place on the map (it's for a battle simulation)

[torn falcon]

Hey can anyone tell me how I would set an int variable in a struct through a bp to then access it and use it to update another variable in a different bp

[runic parrot]

Go to your BP and add a new variable, make it of data type "YOUR STRUCT"

after that, when you want to edit it, grab the variable and drag a new node from it, look for "set members on"

it should look something like this

@torn falcon

[torn falcon]

So then how would I make that info accessible by another bp?

[runic parrot]

click on the variable and check on the right window of "details" (make sure the details windows is showing)

there look for "instance editable" (check) and "private" (not check)

if they are like that, you can access to those variables through any place that has a reference to your BP

[torn falcon]

Ahhh right, thanks man

[autumn plover]

How can I get a variable from a parent for a HUD widget. Only gets the default when using a child.

[elder spindle]

Hi guys, Im very new to unreal blueprints and learning the basics rn. Im trying to make ammo collecting system for an FPS pawn. I came across an issue in making an ammo collectable where i have to use 2 cast to nodes. however It is not working. when my character runs over it, it only plays the sound. I want to set the ammocount variable. any help is appreciated. Thanks

[trim matrix]

well i think the problem is, that you try to cast 2 different things from the input reference "other actor". are those in the same inheritance tree or are they 2 totally different objects?

what are u overlapping there, an ammo box/clip?

[foggy escarp]

Anyone ever have input key simply stop working?
It is in the character and its not just action mapped events but the entire keyboard key.
This isn't the first time I've had this issue and it's not just a single key. It's like once it stops working it never works again..

[elder spindle]

@trim matrix No, they are two different. I want the player character to overlap and set the variable which is in the weapon blueprint. yes it is an ammo box.

[trim matrix]

ok the overlap input "other actor" will then be the character stepping on the ammo box. the ammo count is stored on the player?
more important, did u debug it to see which nodes get stepped through?

if it is the player overlapping, the cast to ak_weapon might fail there...

[elder spindle]

the ammo count is on the ak_weapon

[trim matrix]

yes, but the overlapping actor might not be the weapon

guess we need more info on how your character and weapon are related

[elder spindle]

so, the overlapping actor is my FPS Pawn. but my weapon which is storing the ammocount variable is not related to the FPS pawn BP

If one event cant support 2 different cast to nodes, can I do it with multiple event nodes?

something like this

[trim matrix]

what you could do is, in the character, setup a variable "active weapon" with a type ak_weapon

then somewhere when you equip the weapon, set the active weapon to this weapon

in the overlap method then you can get the active weapon from the overlapping actor (FPSPawn) since it is a member variable

then you can set the ammo count of this weapon

i hope it is understandable for a beginner 🙂

[elder spindle]

Ill try this, Thank you 🙂 @trim matrix

[foggy escarp]

Figured it out.
I had multiple key events for different things on the same key on both the player and the controller.
I just unchecked consume input on the controller one.

[lime fulcrum]

Question about SAVE / LOAD level with all actors.
I'm not asking the code part, but just the workflow.
How do you guys save and load a game? Let's say QuickSave and QuickLoad key.

I'm doing it in the GameMode while using a flag in the GameInstance where the flag tells the game to load from a save slot when the level is loaded. The flag is set when you press "LOAD GAME", it sets the flag to TRUE then loads the level. When the level loads and GameMode starts, it read the flag and as it's TRUE, it loads from a Save Slot and sets the flag to FALSE.

But.... the issue is... I keep getting invalid actors from the list of actors to remove. :\

Do you guys have a better more efficient way to SAVE/LOAD?

Is the GameMode loaded before all the actors in the level?

[icy dragon]

I'm using the built-in Save Game system. Nothing too fancy.

Though granted that my game (which is an action RPG for consoles in mind) doesn't benefit from instant saving/loading system, and all I save are player stats, items, progression flags, position in the world, current time/weather.

[lime fulcrum]

I'm doing the same, I use Blueprints cause I don't know C++

But when and what entity /actor do you use to proccess all the data?

[icy dragon]

I don't store any objects reference in the save game data.

[lime fulcrum]

OH, so I'ts like You can only load chapters of your game

so the player needs to play the level from start each time?

but keeps all the items /inventory etc

Right?

[graceful forum]

I have a performance wise question. Is there a difference or a better approach between usin GetComponentBy class on an Actor without casting it, or directly casting the actor to my known type and getting it's component directly from that reference?

[lime fulcrum]

@graceful forum Have you tried Tags? I don't know if it's better but might be a good test to perform

[maiden wadi]

@lime fulcrumIf you want to save and load specific objects to places rather than checkpoints, you have to save their data you want saved, and their class, and then spawn that class and repopulate it's data after load and set up all of it's states again. In blueprint, this is incredibly tedious for larger projects and very prone to bugs.

[lime fulcrum]

Oh

What would be a good solution?

[steel sequoia]

is this a good place to ask for help with code?

[maiden wadi]

@graceful forum Depends on what you mean by performance. Casting keeps hard pointers so causes the class to be loaded at all times while the casting class is loaded. May not be a problem. GetComponentByClass is more CPU cost, but not by much. Realistically, you won't notice it unless you're planning on checking tens of thousands of actors for this component every single frame of the game. In which case you already need to reconsider your approach. 😄

@lime fulcrum Only a few choices there. Either find a good workflow where you can integrate that kind of system and deal with the edge cases. Reconsider how you want to allow users to save progress. Or learn C++ and do your own Archiving, or buy a save plugin to handle the C++ side for you.

@steel sequoiaIf it is Blueprint and Unreal related, go for it.

[lime fulcrum]

I'm trying out Easy Multi Save plugin right now. Do you know if it's good enough?

[maiden wadi]

Haven't tested it myself. So no opinions.

[lime fulcrum]

oh, ok. Thanks for the tips by the way 🙂

[maiden wadi]

I think I have that though. Might check it out for my own learning purposes.

[steel sequoia]

thx @maiden wadi turns out ive just figured out my issue! I've been trying to modify a variable before I've referenced it

[lime fulcrum]

I'm trying it right now and it uses Interfaces to save actors

Looks like it's based on serialization so you have to set that "Save Game" flag on your variables

[maiden wadi]

Yeah, that'll be pretty common with any decent save system.

[steel sequoia]

aha I've found another error, I've been following devsquad's FPS series and ive found some strange behaviour. Despite copying my code between two different guns, one of them fires the bullet with significantly less force and is very slow moving

this is the code of the slow one ^

and the code of the fast one V

does anybody notice any reasons why this is happening?

[ancient torrent]

@steel sequoia are the variables the same? Copied ones may default to 0

[graceful forum]

Yeah it's not like something happening in tick or all the time or something. I can Just keep the reference of the component for later usage. I was asking which one is the better approach to adopt for getting a component from an actor in general. So yeah I was asking the trade off between hard referencing and using GetComponentByClass I guess

[maiden wadi]

@steel sequoia Get the location and rotation of that transform from the Socket, and forcibly set Scale to 1,1,1. Also check the muzzle location on the broken one's mesh to make sure it's not clipping or close to clipping somehow.

[steel sequoia]

thankyou

I've checked the muzzle location and It appears to be ok

I am unsure of how to get the location and rotation from the socket

sorry if I'm being a pain

[maiden wadi]

@graceful forum Mostly just a slight bit of extra CPU cost for the GetComponent call. I do that with my Inventory Components. I place them on several different actor types and use GetComponentByClass since there should only ever be one of them on any actor. Much easier than casting, or having to have a whole interface set up for it.

@steel sequoiaYou're in a learning channel. If someone makes you feel like a pain, ignore their ego. But to get the location and rotation, you can break the transform and get them separately. All this will do is make sure that the bullet doesn't scale with the gun or socket. So this may not solve your problem if the socket looks correct.

[graceful forum]

Got it, thanks for explanations

[steel sequoia]

thx 🙂

[fair sun]

Hi, I am trying to diable LODs in my game, I used r.ForceLOD 0 and it worked in the editor but it fails when making a test build and uploading on quest, not sure if that's a problem with test builds or android but is there any other way to disable LODS?

[maiden wadi]

@fair sun Checking on that, but it looks like it might be a ini file setting.

@fair sun Uncertain, but it seems you 'might' be able to add that line to the project's Engine.ini file under [SystemSettings]

[fair sun]

I'll try that out

thanks

@maiden wadi Getting

PackagingResults: Error: Unhandled exception: UnrealBuildTool.ConfigCacheIni_UPL+IniParsingException: Failed to find value when parsing Project\Config\DefaultEngine.ini, line 137: r.ForceLOD 0

[maiden wadi]

Try r.ForceLOD=0

[icy dragon]

Well, since it's an open ended Action RPG, I'm primarily keeping track of what quest has been completed or still ongoing.

[lime fulcrum]

That's way easier than what I'm doing. I'm trying to replicate the classic QuickSave and QuickLoad with all the entities saved and loaded

[tame owl]

Hey there, I'm kinda new to making advanced Blueprints, hopefully this type of question is allowed. So, I was wondering if there was a better way to go about doing this. Basically, for our game we had the idea of the player unlocking various abilities/"powers" throughout the course of the game. And my solution for right now was to simply code all the entirety of the ability within the player BP itself and have a boolean that can be toggled on or off to tell if you've unlocked it yet or not.

The problem is, I feel like this kind of system is sorta messy and maybe isn't the best way of doing it...? I've heard about gameplay abilities but the problem with that is that I've heard it requires CPP but our project is an blueprints only project. Basically, I wanted to have a system where I could make BPs for the various abilities and do all of the coding of them there and then add them to the player but I don't know if that's possible using only blueprints. Anyway, I will post the screenshot of how the blueprint is set up right now, excuse the messy nodes and stuff I'm not great at organizing. There's more abilities then just these two but I think you can get an idea with just this screenshot.

[icy dragon]

As in boomer shooters instant save/load? I don't think instant save/load need to be written on disk, but it would be easier if all your enemies are placed on the map, and keep track of their state, stats, and position

[lime fulcrum]

yeah, Half-Life for axample. That kind of Save System

BTW, how do I fix a broken reference in the Component Handler?
I get this because I removed a BP Component but I did remove it from actors and saved before removing the component. It keeps saying: Failed to load /Game/MODULE_SaveGame/COMPONENTS/BPC_ActorSaveData.BPC_ActorSaveData_C Referenced by InheritableComponentHandler

What even is: InheritableComponentHandler

Ok, "Fix Up Redirection in Folder" did the thing it seems

[icy dragon]

My implementation is a mix of C++ and BP, but here's my gist:

The skill tree progression is kept track by a bool array on a GameInstance. The GameInstance serves like the judge of the game who keep track of player stats.

Skill functionalities are separate classes storing animation montage/sequence, and attack stats.

Player character calls for that skill class and execute it. They don't need to do the check, since GameInstance stores what skills are unlocked.

If that doesn't make sense, I'll elaborate more on it later.

[lime fulcrum]

I think it makes sense. I use GameInstance to keep variables between level loads

[lusty elbow]

On ue4. If I want to have a bunch of characters, enemies and locations with their associated attributes, which data type would be optimal to store their information?
I am assuming a struct for each of those, stored in the game instance?

[fair sun]

It packaged but LODs are still there:(

[maiden wadi]

Splat. Supposedly you can run that as a console command at runtime. Not sure where or when you'd need to do that or how often(Like after level loads).

Worth asking, what are you avoiding LODs for? They're pretty big for performance.

[icy dragon]

LOD can be used even for linear games, doesn't have to be an open world only thing.

[fair sun]

I actually need to compare performance for Lods vs noLods. I ran that as console command but with no results, could oculus/android block that?

[maiden wadi]

@lusty elbowThat is an incredibly open question. It'll be hard to answer without more specifics. What are you storing this information for? Usually it would just exist on the objects themselves. If you're avoiding spawning them for performance reasons, then it still depends on the game type. If you're using one large world, you likely need an AI manager that can spawn/setup/destroy/save these things at runtime based on conditions like whether the player is nearby. Also avoid putting too much data on the GameInstance. You'll eventually run into bugs where a player will load one game and end up with another's data. Good coding can avoid it, sure, but savegames are the same, safer, and not prone to having left over data between loads when done correctly.

One of my favorite examples of systems like that is probably the X series. Nearby ships are actually spawned in and displayed in 3d as objects. But in the map, you can see a whole universe of moving things. Except that things not near the player are nothing more than simple data being ticked every couple of seconds. So they can still "move" and do things in the background, but without the extra cost of existing. Writing an AI manager system could handle that for you depending on what you need.

[lusty elbow]

Mmmmh. Thanks for the answer. I will look into it! I'm still open to additional answers, of course

Ok, maybe I can add more information.

Basically a vehicle spawned on a simple top down map and a "home base". There are about 12 characters, each with their associated data (Health, Morale, Name, Equipped items, etc), but their 3D models are not spawned in the level. Only the vehicle and the home base are. Say 4 of said characters jump into the vehicle and go roaming the map. They find a settlement and get down the vehicle to explore. So the level changes from the strategic map to the level of that settlement and the 4 characters are shown.

I believe the X series example would be close to what I intend. As I just want to store data persistently from start to end of the game session. I don't intend on spawning too many 3D models at once. Any recommendations for this scenario?
Sorry if I'm not explaining myself correctly

[maiden wadi]

This would be a little easier doing it through C++, but from a pure blueprint standpoint... I'd probably store their Data in Savegame between levels. While in game, have a component attached to your GameState that gathers the data from the save and stores it for game use. You can easily get the component via GetGameState->GetComponentByClass. So doing this you can even keep you Strategy and InMap Gamestate different classes if you need to. Add characters to car via FName property or whatever other ID you want to use. When car reaches other map, you can save it's data before map load along with everything else, and retrieve the array of characters in the car. You can then use this array to retrieve their data from the Component on the Gamestate to populate the 3d Actors. Doing this will allow you to easily create them on load of map, as well as pull UI information for your strategy level. At the end of the in game level, you simply retrieve the actor's information that can be affected in the level, update the component on the Gamestate, let it save, and then load back into the strategy map.

[lusty elbow]

Thank you for the answer! It seems that I need to learn more about "Game State" and its relationship to "Game Instance".

[maiden wadi]

There isn't one so much. GameInstance is just an object that persists all level loads and exists from the time the application is open til closed. Nearly every other object is destroyed and recreated every map load. GameState is just an actor that is commonly used to hold the state of the game. In singleplayer it can be whatever you want it to be. It becomes a little more apparent in multiplayer because GameState is often used to display stats to all players about the current state of the game.

[shrewd oar]

Hello all. Do i miss smthing here? im trying to make this mesh (this is a key) invisible when playing. for some reason he is still visible. (he is moveable)

[icy dragon]

Try enable Propagate To Children.
That BP script assumes you only want to hide the root component, not any other components parented to it.

[lusty elbow]

Mmmmh. Thanks! I'll learn more about the topic and I'm sure more questions will pop up. Thanks once again!

[lofty orbit]

how can i add an actor as like a subactor of an actor

in unity they are called children

how do i add children to an actor at runtime with blueprints?

[shrewd oar]

Thank you soo much Didnt notices the children bool

[wise raven]

Can someone tell me how i can make the for loop functions run every 0.5 seconds of a tick?

[surreal peak]

Isn't that a pure #graphics question?

[elfin robin]

Not really since I can't plug anything out of it now

Or in

[surreal peak]

But that's a material editor issue

[celest pagoda]

So i have an Attack function that gets called from a behaviour Tree. Does someone know why i cant use the "Play Montage" Block (which has a On Begin Notify output that i need) within the function blueprint? I can only call it from the Event Graph from the AI but not in the function blueprint. This is the block i want to use:

[surreal peak]

Because latent nodes can't be called in functions

[celest pagoda]

How can i check for an animation notifier in a function then

[surreal peak]

Implement the notifier in the AnimBP or use a Notifier BP maybe?

[celest pagoda]

Ah the first one would work i think

Cheers mate

[wise raven]

Does anyone know?

[stray island]

Hmm will it work if you add it after a (delay) 5 seconds after event tick or a timeline?

[fair sun]

If you double click the for loop you will see a macro that executes inside it, you can copy it to your own macro or add a delay

second option would be to delay for x * index in loop body but that's not reusable

[wise raven]

Where should i add the delay?

@fair sun

[wise raven]

um not sure

[fair sun]

after then 1 should be fine

[wise raven]

oh man a delay cannot fit in that macro

ill use a custom macro

a delay can come in that

[surreal peak]

They did tell you to make a custom one :P

Don't edit the engine one haha

[fair sun]

I want to open level through game instance and bind an event on my game mode, but I need to wait till the level opens because the old game mode gets destroyed, is there some delegate that runs when you open a new level?

[open crypt]

Is there another viewmode to show collision? I have game mode on while i simulate and i've set it to player collision but I can't find what this thing is running into (and I'm confused that's what happening) - all the other AI controls that this vehicle uses somehow don't show what it's hitting

[fair sun]

the delegate on the game mode runs quite fast after begin play so a simple delay would be a terrible race condition

[open crypt]

If I move the landscape, road spline (what the cars use to navigate) up super high away from the rest of the level, they don't have any problem

both these are coming back as none, so if it is another object, I can't see it in the editor before runtime and I can't turn it on to show what else it could be

[gritty aspen]

why it don t work

[open crypt]

son of a bitch....i think it's hitting the foliage

[gritty aspen]

what

[open crypt]

sorry I'm trying to fix my thing

[open crypt]

But for your issue, hit f9 on that overlap red node

and see what happens

[gritty aspen]

ok

i did

and still don t work

[open crypt]

then it's nothing is overlapping - which means you have a collision channel problem

[gritty aspen]

well

no

the collision work

[faint pasture]

@gritty aspen hit and overlap are different things.

[runic parrot]

does anyone know how i make this window size to whatever the size of the screen is?

[timid rune]

Are you asking how to make it the size of that screen there, or does the screen size change?

[runic parrot]

i wanna know if in the case that the screen size changes, if there's a way to make that window the same size of the screen

[timid rune]

Is it possible to bind the size

I just checked, it isnt

Ill try to figure it out and let you know

[onyx token]

work with anchors

[timid rune]

I don't think that will change the size though

Oh got it

[runic parrot]

that's what i was looking, thanks!

Question-
I made an interface so my widget & my third person character blueprint can talk to each other-

But i can't drag it in 😦

[runic parrot]

look for event "right", "left", etc.

oh lol.

im dumb.

thanks XD

[edgy glen]

Hi, I was wondering if it's possible to change a Physical material friction in blueprints, I can't find a way to do it and the reason I'd like to is because when my car drifts by changing material itself, it jerks back into place when it stops drifting, I would like to smooth it by changing the friction value itself with a timeline

[runic parrot]

Another question, i started a project with a blank template, is there any way to import the mannequin asset (mesh, animationbp, etc) to it?

[edgy glen]

Yes, if you have a project with the third person template, you can export the assets you'd like and import them into a blank project, I like to start from scratch so I have done that a few times

You could also choose migrate, both are under "Asset Actions" when you right click on the asset

[runic parrot]

nice, thanks

[edgy glen]

No problem 🙂

Is there a way to bind an event to when an animation sequence is finished? I want to play a different animation but I don't want to bother in the animation blueprint if I can call an event that plays a random animation sequence

[runic parrot]

i have no idea, but you may get a good answer on the animation channel

i'm getting such a hard time getting the camera position to look like this

am i doing something wrong or is it just because those are 2D sprites and mine are 3D models?

[faint pasture]

@runic parrot try an isometric camera

[runic parrot]

yeah, i'm trying to get a good angle that looks like isometric camera

i also think i need to change to 2D sprite looks in order to get a similar look

[edgy glen]

I think most angles in isometric games are between 45 and 55 degrees

[runic parrot]

this is 45

[knotty briar]

the problem is the actual sprites I think

you'd need to actually INCLINE the mannequins themselves

same reason Legend of Zelda is not really top down, you'd only see the hat

[edgy glen]

Oh yeah I remember seeing this thing on Zelda for the 3ds

[knotty briar]

exactly

the sprites themselves are moved as well as the camera

[runic parrot]

that makes sense

i'm gonna switch all the models to 2D sprites and try that later

oh wait, that one is 3D and looks quite nice

i'm gonna try that

okey i inclined it -45*(x) and if i use the Top down view it looks way better

i'm having troubles on positioning the camera to get the same angle as the "TOP" view, since i'm using a SceneCapture2D

[west wigeon]

I seem to get this error when starting up my packaged game, and ive gone to both objects above and recompiled/saved them, but it doesnt fix it?

[runic parrot]

Okey, so i got the view that i want, but i'm having troubles getting a camera with the same view.

This is the view if i use the editor's TOP view

And this is what i get if i use the camera with some angle

Any idea on how to replicate the first one, but with a camera?

[thorn sleet]

Hi, It is possible to create a blueprint class that is not an actor ? that has no position, that is not an object that will exist in the world

[runic parrot]

yeah

[thorn sleet]

OK.. I'm dumb

Thanks

[maiden wadi]

It's worth noting that objects still need to be held within Actors. So you'll need GameMode or GameState or something to hold that object.

[thorn sleet]

Should I make an Class in C++ directly ?

[runic parrot]

It depends in what you want to do

[surreal peak]

You can hold objects in the GameInstance too which is for example not an actor :P

[opaque forum]

Why this doesnt work?

But this one does...

[mint wraith]

how to smoothly move camera while change between 1stPerson view and 3rdPerson view?

[runic parrot]

Does anyone know of a good way to equip weapons on a 2D flipbook? i'm trying to not create a diferent set of flipbooks for each weapon.

[misty gate]

How can I get the velocity of an object if my only reference is from a Hit Results Structure?

[gritty aspen]

i did a ai spawner but when he spwan the ai the ai don t move

[fiery swallow]

Can you decrease the value inside of a MAP without resetting it?

probably not

[faint pasture]

@runic parrotI mean switch the camera to actual isometric mode

[surreal peak]

Make sure your AI Character is set to work when spawned

There is an enum in the class defaults next to the ai controller variable

It might be set to worked only if placed in the level.

[fallen glade]

I've been really struggling with this really simple thing. I'm just trying to make a set of spline meshes disappear gradually like the white gradients here. I've tried so many combinations haha but nothing looks good yet. any idea?

[surreal peak]

Looks more like you want to modify the first few points of the splinemesh and not just start and end

[fallen glade]

well i'm trying to get each mesh to shrink from start to end ? I guess i'm really confused it sounds so simple

[surreal peak]

Doesn't look that simple hehe

Not sure atm what a good solution would be. The Timeline seems to static to do this.

You kinda need to scale multiple points at once but offset in time and then remove those points when they reach 0

[fallen glade]

well it's a value progression from 0 to 1, should be enough no? oh I see I haven't though about doing it that way

I've only been playing with math

i'll give that a go

thanks 🙂

[surreal peak]

You could try math but you still need to scale all points eventually

You could use one Timeline and apply the current scale of the timeline but adjusted by the current index

E.g. If the first index goes from 1 to 0 in 1 second

[fallen glade]

my most successful attempt was to gave 3 different remaps of the line progression but it was way too crude

[surreal peak]

Then the second index could be mapped to 1 to 0 in 0.9 seconds

Etc

[fallen glade]

YES!

that sounds perfect!

in my head haha i'll report back!

[surreal peak]

With a bit of math you could first calculate how big the diff should be between each index and then use that

One idea would be adding ontop of the scale for each point. So 1 to 0 could be mapped to 1.1 to 0. And then clamp again. That way the second index would take a bit longer befote it actively starts going below 1 scale

Third index could then be 1.2 to 0 etc

Not sure how to math out the exact value you want to add ontop though

pretty sure you can figure something out

[pseudo pelican]

does anyone know if there is a way to change the playrate of an animation montage mid montage?

e.g: slow fast slow

[icy dragon]

#animation

[fallen glade]

I did 🙂

[surreal peak]

Honestly, seeing that, you might have better down that with a material haha

[fallen glade]

how xD?

[surreal peak]

But cool effect. Also thanks for triggering my arachnophobia lol

[fallen glade]

sorry

[surreal peak]

Idk how exactly, but I'm relatively sure you can do that via a material

But if it works for now, just leave it

[fallen glade]

I guess it could be a simple gradient opacity mask or something, anyway yeah now I can do something else! Thank you for your help!

[trim matrix]

Why is this happening?

[maiden wadi]

Why is what happening? The context menu showing when you let go?

[trim matrix]

Nvm, the video is not showing it, thats so weird

Its actually that the box is disappearing

but the video is showing it as staying there

[maiden wadi]

You got bugs. Should ask Silver to get his spiders to eat them.

[trim matrix]

could it work if i just restart or is it that I've done something wrong?

[maiden wadi]

Restart may work. I've never encountered that issue myself.

Validating engine files is also a consideration if you have time.

[trim matrix]

Okay, if it's because I've made a mistake somewhere, I'll be really confused because I'm using a tutorial to do this.

[maiden wadi]

Does it show if you just normally right click somewhere in the graph?

[trim matrix]

I restarted it, it's fixed : )

[wispy star]

Is it possible to run the construction script if one of the actor components was modified in the instance?

[wispy star]

add breakpoint on all events, make sure they are all triggering, then watch all values, make sure they are all getting updated

Seems like the function Update Health AI isn't getting fired but I can't find a way why tbh.

[rich axle]

Hey Guys, is there an Idiomatic way to use Blueprint? Like best practices in "Code" organization and does and don'ts as there are for the C++ side (Coding Standard).
If so, do you have any good resources? I am talking about some good rules to follow in a professional environment to make code maintainable and scale-able.

[fast fiber]

Having some issues with manipulating rotations in blueprints, not sure if I'm doing something wrong

The grey wheel spins on top of the white wheel

the pillar is locked to the grey wheel

the orange wheel can spin on the pillar

I want to make it so the angle of the wheel on the pillar matches the angle of the bottom wheel

What I've tried doing is getting the relative rotation of the constraint for the pillar wheel (which is highlighted in first pic)

Then using Rotator from axis and angle to combine the relative x-axis of the constraint with the twist angle of the bottom wheel

then applying that rotator to the pillar wheel

but it doesn't work right

here's the blueprint I have:

And here's the behaviour when I run it: https://streamable.com/g5icfr

[rich axle]

Thanks for the swift answer. However these are all pretty common sense. We often have the problem between non-programmer "artists" doing exactly that and the more organized/clean architecture approach, which of course also takes more time and effort to mantain and design. And every meeting is basically a discussion, why the spaghetti / one graph approach is just not right, eventhough it is faster and not as difficult. They're argument is that it works either way. However they just have been lucky so far that it didn't break apart yet. Feels like a House of Cards to me and I am just anxiously waiting, that it crumbles, but I can not get it into their head. If there was something "official" from Epic along the lines of "does and dont's" they would listen, because the Senior Designer is a hardcore Epic fan boy, and would blindly follow anything they say. lol.

[wispy star]

well, if it's a server function, make sure it's called on server, make sure the caller exist on server (as UI does not exist on server, and player controllers are not the same on client and server etc)

Have anyone tried to bypass this issue?
https://issues.unrealengine.com/issue/UE-28690

[rich axle]

Unfortunately not. You have to understand this person's mindset. He is so full of it. He once told me, thanks to Unreal Engine the job of programmers has become obsolete because he has an "Artist" can now do what programmers can but with a way more powerful tool. And that arrogance just shows in his way of coding. Complete garbage. That's the level of ignorance I have to deal with day in and day out. I am a freelancer fortunately however by best bud has to deal with it every day as he is employed as Junior there... It is a horrible predicament. So that's why my last resort was to look for some Unreal Engine commandments, like a Blueprint Bible to save him from insanity 😄

You are absolutely right!

[maiden wadi]

Tell him to copy the CMC into blueprint. I wanna see this.

[rich axle]

Exactly!

[crimson hornet]

Sorry but what do you mean by this?

Like this?

[rich axle]

hahaha ^^

[maiden wadi]

I'd like to point out something obvious too. You said it yourself. You're a freelancer. You get paid to do what they ask. If they continually mess things up that were not in your hands, it's not your responsibility. If they do mess things up that are in your hands, your responsibility ends at explaining why it failed and telling them the better approach. If they ignore it, it's no longer your problem.

[rich axle]

I mean, I think we had this line of conversation in the C++ section already. I am a self thought programmer myself. Everything I learned was from my projects, books and youtube. However I try to adhere to good programming practices and I am a sucker for good architecture and clean code ^^. I lack the fundamentals however to explain to someone else why some code "feels" better than other. But this is becoming more of personal gossip now, so I will end this conversation here. Thanks again for giving me the glance of a moment of being understood 😛

[maiden wadi]

Also a pro tip that most people don't know. You don't have to reroute Function arguments in blueprint to get a function argument at the end of the function. You can get them directly.

Cleans up a lot of BP functions.

[rich axle]

Isn't an argument that sticks with him either. He says, well then get a better computer. LOL ^^. This guy is just insane.

Unfortunately he can. It's one main costumer (can't tell you which) but he can afford that. It's a pickle.

Oh I wish I was this non-idealistic. ^^ But thanks for the chat. Was great.

[wispy star]

is your code for multiplayer?

@maiden wadimost people don't even know what PURE means in UE4

[rich axle]

Good rule! ^^

[maiden wadi]

It's a good tip though. I see a lot of people allocating extra local variables to hold things for the end or doing big huge long reroutes.

If you even have a couple of logic branches, that reroute gets messy fast.

[rich axle]

So what you are saying is you can call the Function input as if it was a local variable within the scope of the function as shown in example pic. 3? That's neat, I wasn't aware of that either!

[tight schooner]

I think that's a relatively recent feature

[maiden wadi]

Not sure when it was added. I did a ton of my learning on 4.25

[wispy star]

@rich axleall function inputs are local variables, cause it's how c++ works

the only issues i had were passing references

as arrays can't be passed as reference for some reasons

[maiden wadi]

How do you mean? I pass arrays by ref all of the time.

[wispy star]

reference variable has diamond icon

[wispy star]

gimme a minute, i need to open ue4

[maiden wadi]

This will print 4, and then 0.

[rich axle]

I think what Alexey means is a function argument passed in by reference to create a level of indirection. So the function operates on the variable without having to return it.

By the way: (Out of curiousity) Would this be an "Array of Float references" or a "reference to an Array of float values"? 😬

[maiden wadi]

Reference to the array. Fairly sure you can't have an array of references in blueprint.

[lost solstice]

is there a way to make a cone collision / trace similar to pawn sensing components or not really?

[maiden wadi]

You could easily do multiple traces in the shape of a cone. Nothing native, you'd have to do that yourself. Or just use a cone static mesh and use it's overlaps and hide it in game.

[lost solstice]

i might go with the static mesh option. Crazy they dont have something like that when they technically have a component with that functionality. Thanks though!

[thorn sleet]

Hello, do you have an idea for my Pawn to stay glued to the ground without using physics and have correct performances, or maybe better way just ? For the moment I use a Raycast at the position of the actor with the beginning: Z + 200 and end: Z - 200 and I ignore self on the event tick.

[icy dragon]

Is Character Movement Component and Capsule Collision too much for you?

[thorn sleet]

Not really, but I was looking for a less complex solution

I don't have any character, mesh. I don't really need physics thing

[cedar coral]

in the capsule component under collision presets, is there an easy way to ignore character? I see "ignoreonlypawn" but my guys are characters and I dont want them to get stuck in each other D:

[steel sequoia]

this code keeps degenerating itself and stops working, all i have to do is replace the "target - enemy health" with itself and re-compile and it works. Is there a reason why?

[rancid cloud]

Did you find a solution? We're actually doing the same thing 😂 Mine i use for crowd NPC

[rancid cloud]

I'm not sure if i get the whole context but placing it on Event Begin Play triggers your code only once. 🤔

You need another event for it to do it again

[steel sequoia]

it just randomly breaks after i compile it a few many times

Im not even changing anything that has any relation to any of that code in between compiles

[summer jetty]

Good morning gurus! SaveGame question: do I essentially need a copy of all the SaveGame variables in my gameinstance (and specific variables in other blueprints that read/update them - for example, the ChatName variable in the character creation screen)? Want to make sure I’m not giving myself needless extra work.

[icy dragon]

Yes, the GameInstance keeps track of current stats, and SaveGame make a save slot by copying what GameInstance keep track of.

This works well for single player games, but multiplayer with dedicated server might store the data directly on the server.

[summer jetty]

Ok, that’s cool. So the saved slot updates the variables on the gameinstance, then the gameinstance updates the variables used on the other blueprints (and then the other way around to update those variables in the slot)?

[thorn sleet]

I'm forcing the location of the actor, with an raycast impact point. That's what you're looking for ?

[rancid cloud]

Yeah, i'm doing the same. Raycast and move component to location for the NPC. My issue (that i might need to live with for now) is that it wont stick right away to ground while "Move Component To Location" is executing because its time based, i.e. it moves to target location regardless of elevation and after that is the only time it would adjust itself wrt the ground

[sonic pine]

Hiho, I'm looking for a solution to be able to read out the data from items.

Ok, let's start at the beginning.
I have a ParentAxt_BP, this is connected to the AxtStats_Structure.

Now have 3 weapons in my inventory.
Small battle ax, medium battle ax and large battle ax. Each weapon is an Axt_BP_Child whose values ​​are entered in Axt_BP_Child.

General data are stored, for example:
Axt_BP_Chil01
Name: Small Battle Ax
Physic DMG: 15
Strict: 5
SellPrice: 35

The question is, how can I read out these values?
The values ​​are not individual variables within Axt_BP_Child01-03

Another problem is that the player can change the weapon at any time and thus also the values ​​change, but not the variable names.

this is the weapon Slot in the CharacterStats Widget

[gritty aspen]

guys how can i add a sound to a widget

[sonic pine]

This is a Child of Master_Axe

[sonic pine]

Do you want to set a OpenUp sound or a background sound when the Widgte is open until its closed?

[rancid cloud]

Hi guys. Could you help me how to implement a jump forward in BP (3d space)? I thought it was easy but it's actually hard.

Its unlike the default 3rd Person level, where when you jump, you could move forward in "floaty" way. I need a jump that really thrusts you forward

[thorn sleet]

Can't you add a force ? something like that in a direction

[surreal peak]

"LaunchCharacter" if it#s just a singleplayer game

[rancid cloud]

I actually tried both add force and launch character but i cant seem to make it work

Is Launch Char or add force should be a continuos tick or only once?

[surreal peak]

Force is probably wrong

Cause that's more for physics simulations

Launch Character needs to only be called once

[rancid cloud]

I'll retry Launch Char. 👍

[gritty aspen]

yup

what event i put

[wanton ginkgo]

there an easy way to cast to player state from game instance? or the other way round can't find what links them

[azure sparrow]

Hello! I am using a foreach loop. Can anyone tell me why the next node of the foreach loop isnt getting called? I used a break to test it out

Note: It works when i give it a different array other than the crafting slots array

[maiden wadi]

Array has no indexes.

@wanton ginkgo You can get the local player's playerstate from GameInstance via GetPlayerController0->PlayerState. PlayerState can get GameInstance via just GetGameInstance.

[runic plinth]

Hi quick noob question here, don't know how to google it in short words, where do I have to look for some kinda of scaling of the material? For instance the print shows a floor and the rock material is way over stretched.

[maiden wadi]

Worth noting not to use GetPlayerController0 with Seamless server travel.

@runic plinthIf that is a static mesh plane, you need a material instance of the floor material that can affect the material's UV scaling.

[runic plinth]

Thanks I think I got a forum post to follow on. It's somehting along those lines right?

[maiden wadi]

Pretty much. Just make a Scalar Parameter in the material. Name it like.. Scale. And then make a Material Instance of the material, and you can set the scale to whatever you want.

[runic plinth]

Thank you for your time 🙂

[summer jetty]

I created a custom gameinstance blueprint and assigned it as the project gameinstance class. Today I opened the project and the blueprint seems to have disappeared. I can still see it in the Unreal Projects folder. It just doesn’t appear in the editor. I can’t add it manually either. Has anyone else had/resolved this before?

The log says the file contains unrecognisable data and is unknown file type

[steel sequoia]

was this block removed?

[surreal peak]

Doubt, why?

[steel sequoia]

cant find it

[surreal peak]

It's a function of the PlayerController

So if you have context sensitivity on it won't find it unless you pull from a PlayerController

[steel sequoia]

that was an old screenshot from 2015 with the block in it

how do i do that?

nvm

worked it out

srry

[surreal peak]

Multiple ways. The dirtiest is to call GetPlayerController

The cleaner one would be getting the Controller relative to where you are

If you are in the Character, you can do "GetController" and cast that to PlayerController

[steel sequoia]

you mean like that?

[surreal peak]

Yeah

The Hint is the text below the Node Name

"Target is PlayerController"

That means that the function is part of the PlayerController class

[steel sequoia]

ah ok

i get that

[surreal peak]

And you need at least a PlayerController or a child of it

Also

What you call block is actually called a Node

[steel sequoia]

what would i put for my object wild card here?

[surreal peak]

The actual Camera Object

[steel sequoia]

ahaha srry, ive jumped from scratch to this

its a seperate actor is that a problem?

[surreal peak]

It's not exactly a problem. It's a big learning step for beginners

The ViewTarget needs to be an Actor, so that is correct

But you are lacking the knowledge of how to properly reference an Actor inside another one, which is totally fine.

Your Camera is somewhere in the Level?

[steel sequoia]

yup

[surreal peak]

Is it more than one Camera or just one for that?

[steel sequoia]

nope

just one

[surreal peak]

Okay, so the best way to do this is to let the Camera "register" itself somewhere where you can reach it

Others will tell you to just use GetACtorOfClass, but that's the worst youc an do

[steel sequoia]

ok

[surreal peak]

An example of what you can do is this: If you have your own GameState class, or even GameMode if it's singleplayer, you can always get that from nearly anywhere by calling GetGameState or GetGameMode

So what you can do is add a Variable of the Camera Type Reference in your GameState or GameMode

[steel sequoia]

ah can their only be one game state?

[surreal peak]

And on BeginPlay of your Camera you can get the GameState/GameMode and set that variable

Yeah

[steel sequoia]

ok ok ill try that thx

[surreal peak]

So the Camera sets the Variable with "self", which is basically the object itself

Also called "this" in C++

You can then later get the GameState/GameMode everywhere else

And access the variable

So you basiclaly bridge the missing link between your two actors with the GameMode or GameState

[steel sequoia]

i dont think i have one

[surreal peak]

GameState might be the better choice in genera though

No GameState gets created runtime

Same as GameMode

Do you have a GameMode class already?

[steel sequoia]

i dont think so

[surreal peak]

Right so there is a big gap of knowledge :<

[steel sequoia]

yup

i've been watching tutorials mostly

[surreal peak]

You can create your own GameMode class. That GameMode class defines what GameState, PlayerState, PlayerController, PlayerCharacter et.c classes you wish to use for the GameMode

[steel sequoia]

so thats which actor you control stuff like that?

[surreal peak]

Sort of

[steel sequoia]

ok

[surreal peak]

GameMode is pretty "Unreal Tournament" like

It defines the rules of your game

You usually have one for your MainMenu, and one for your Gameplay

Same for the other classes

[steel sequoia]

also side note, is their a way to make some objects only physically interact with certain actors

ok

[surreal peak]

Yeah via Collision Types and Profiles

[steel sequoia]

thx

will AI pick up that it can walk through that new object?

[surreal peak]

Collision obstacles can be set to not affect navigation

[steel sequoia]

thx

If i just drag in a camera

without it being attached to an actor

can i broadcast to that?

[surreal peak]

Everything in your Level is an Actor

If you drag in a mesh for example it will spawn an Actor with the mesh in it

[steel sequoia]

ahhh i get that

[surreal peak]

If you drag in a cmaera it will spawn a camera actor

There is no way of having a 3D "object" that is not an actor basically

[steel sequoia]

ok ok i get that

[surreal peak]

At least in general

But yeah, you will want to create your own GameMode or use the one that your project comes witzh

Probably has some ThirdPersonGameMode or so somewhere

And also have a GameState

And set the GameState Class sin your GameModes ClassDefaults

Then you can call GetGameState and cast to the class to access your own functions and variables

[steel sequoia]

ah yh i think theirs a third person game mode somewhere

i see it now and then

[surreal peak]

Yeah it's probably set on your Map by default

Or even your project (Project Settings -> Maps and Modes)

[steel sequoia]

i found the third person game mode

[surreal peak]

What does it say in the top right corner if you open that

[steel sequoia]

oh oh one more thing

parent class: game mode base

[surreal peak]

Right, then you need to make a GameStateBase child

Instead of GameState

[steel sequoia]

can you read someones username? like their account name on the computer

[surreal peak]

or reparent the ThirdPersonGameMode to GameMode

Yeah, the PlayerState has the UserName

By default that'S the PC name

[steel sequoia]

thx 🙂

ok so how should i go about swapping the players view to a separate camera?

[autumn plover]

Do you guys recommend making adaptive ui/huds?

[celest pagoda]

I try to fire a particle system based on an anim notifier of the animation that i play. Can someone tell me why its not working ?

[long compass]

I'm trying to take my actor's forward direction and get the rotation that would make it point toward 0, 1, 0. I'm using FindLookAtRotation to get back a rotator. When I apply that rotator to the actor's forward vector, it does not give me the expected vector, 0,1,0. Am I misunderstanding something fundamental?

Or: is there a better way to accomplish this? I'm trying to build a minimap system and I need to calculate the angle between my player's forward and the vector that points to the target player. I think I've calculated the angle correctly, but it only goes from 0-180, so I need a way to determine whether the target player is on the left or right side of the player so I can render things correctly. I thought applying a rotation that brings the forward vector to 0,1 and then applying that same rotation to the other vector would be a reasonable way to approach this.

[fading wren]

hello there, still have situatition to solve. Ball is player, i would like to player rotate 30 degrees to right or left dependeing on player direction at the momemnt when player hit a wall. in situation A i would like to rotate player to 30 degree to left, and opositive in situation B

https://cdn.discordapp.com/attachments/455044559240429568/863833847581507584/unknown.png

[long compass]

You could set up two collision capsules / boxes on the wall and have different overlap events fire when different capsules are hit.

[fading wren]

is it optimized method ?

if ball hit them both

[long compass]

I don't know what you mean by optimized. That's a good point about if the ball hits them both. You'll probably need some logic that can handle that case.

Depending on what you want the behavior to be.

[fading wren]

i need use some vector math for sure

but i am only beginer

cant find out how to do it

[long compass]

Oh, do you want it to be variable amounts of turn depending on where they hit? Example: you want the angle to be higher if they hit further away from the center?

[fading wren]

no, fixed angle is ok, i just need game understand rotate player to right or left

[long compass]

Oh, if that's the only challenge, I think you can just use RotatorFromAxisAndAngle and apply the resulting rotator to the ball. (though if that's the player, you might need to apply it to the player controller or something)

(I'm a beginner too, hopefully this helps though.)

[fading wren]

interesting

will check it out

[maiden wadi]

Personally, I'd just do it on event hit of the player's capsule component. Inverse the hit direction, so that it's pointing away from the player, transform it to local space, compare if it's positive or negative Z. Choose left or right based on that. Bonus that if you want the scaling Daniel mentioned, you already have a value that you can use to scale from.

[fading wren]

" Inverse the hit direction, so that it's pointing away from the player, transform it to local space, compare if it's positive or negative Z. " please, could you name a node for this, i am only beginer

=))

🙂

[faint pasture]

@fading wren compare velocity and impact normal

[faint pasture]

That would work too

Start by typing stuff like "transform" into the node search box

What you want is "inverse transform direction"

[fading wren]

do i understand correctly velocity = vector that showing speed

[maiden wadi]

I don't have the ability to test at the moment, but more or less this if I'm still thinking clearly. 😄

[long compass]

You guys seem to know what you're talking about 🙂 Any ideas on this one? #blueprint message

[fading wren]

thank you very much

[long compass]

Or better approaches welcome. I just need to get another vector in terms of the first one. IIRC from linear algebra it'd be something like a transformation of basis, but I can't remember how to do that and I also thought one of these builtin rotator functions might work just as well

[fading wren]

also have a question, why you doint Inverse transform location, if you already multiply normal to - 1?

[maiden wadi]

Those are two different things. Multiplying a facing vector by -1 will reverse it's direction.

Invese and normal Transform will take a local or world space vector and transform it into or out of that transform's space.

For instance. Say you're standing at +200X in world space. You have a location at +300X in world space. You inverse transform that via the actor's transform, and it'll now be at +100X in local space.

[fading wren]

i am not understood it comleptly

sorry

[fading wren]

you mean if we had Local space it became a world space, if we had world space it became a local space

?

[maiden wadi]

Depending on which transform type you use, yes.

Inverse is from world to local, normal Transform is from Local to World.

[fading wren]

aaahhh\

ok

also i am not sure, if i can use Rotation from Xvector to rotation of actor, since i am using

i need use something like add impulse

perhaps

[crimson hornet]

Yes, sorry for late reaction

[long compass]

Alright, I think I'm onto something. Not sure why all of these other things didn't work, but doing RotationFromXVector on my forward and passing it in as the second argument to Delta (Rotator) (with a blank rotator as the first argument) gave me a rotator that, when applied to the forward vector, forces it to end up being (1, 0). I think I can work with this at least.

[wispy star]

well, that means you need to keep in mind what exist on server and what on local machine...a lot of stuff does not exist on server, and a lot of stuff on server is not the same as on local machine

Which node should i use to avoid this warning?

[surreal peak]

You need to use those nodes in the EventGraph of the AnimBP

And save the result (Holding Type) to a member variable of the AnimBP

[robust panther]

Ah ait

[surreal peak]

Then you can use that variable in the StateMachine

The nodes you are using there aren't marked as threadsafe

[static charm]

those last two vectors are nearly equal, especially within a tolerance of 20 lol.

checking the source code for vector equals looks like this should work as intended

[surreal peak]

Print the Vectors before adding them and check what you get there
