[maiden wadi]

So. To use for everything? Not really. Sometimes it's best just to keep the code in the actor class. Sometimes it's better to not even use components and do logic in simple UObjects.

[grand sky]

@maiden wadi thank you for your reply. It's very useful 🙂

[worthy carbon]

Can you tell me how?

[grand sky]

Wait a sec, I will draw for you

[worthy carbon]

Oh thanks!

[grand sky]

I dont know this is the solution for you but it's work for me before

Choose your slots that will be initialized and resize

[worthy carbon]

Oh thanks!

I will try it out

[velvet swallow]

Hey Everyone,
I got a little problem wit my Inputs, I am actually not sure it is a Bug or if I have to set it up differently.
I want to show a UI-Widget while pressing a input-button(Tab), this UI-Widget has buttons (to be clicked with the cursor).
I have accordingly bound a show and hide function to the Button pressed and button released events.
Now this works without a problem.
But when I now click with the mouse while I am holding Tab (to show the widget).
When I click on the button, instead of executing the button's on click event. The on release Event for the Tap-input is executed. And the click on the button is not registered. When I then stop holding Tab and press it again, I can click on the button as expected/wanted.
Closing and reopening the the Tab Overlay, it still works.
Only when I click on something else and then open the Overlay afterwords, the first click again, does not register but instead executes the input-released for the Tab button.
I am assuming that the cursor switches between UI and regular input? Is there a special way I have to manage mouse clicks if I want them to be used for UI buttons and as Game-Inputs? Like constantly tracing if the Cursor is currently over UI or Gameworld?

[gentle urchin]

Gotta see some logic for this really ^

[velvet swallow]

This should be all

[muted halo]

Hey guys, Im using the Geo Referencing plugin and currently have the information displayed on my screen using the built in widget. How would I be able to cast those coordinates to a print string?

[gentle urchin]

How about letting the ui listen for the release ?

Could this be focus related... 🧐

[undone willow]

do you have to use tick for fall damage?

[maiden wadi]

OnLanded

[undone willow]

the only decent bluprint i saw online uses tick but my tick is so huge I don't wanna crowd it

onLanded!

[velvet swallow]

So I tried to just remove the release part and see what happens. So when I press Tab it just opens the Overlay and stays open.
Clicking on the button immediately executes properly. (My assumtion was that I maybe had to click twice, because the Widget was not focused, like you suggested. But since the click gets executed properly on the first click after opening the Widget, that does not seems to be the problem)

[gentle urchin]

Ugh, this sounds scary I'll admit

Like, are you doing that much that really needs to be updated every single frame ? 😅

[velvet swallow]

Further confusion:
I added some empty code to the on release now.
When I click the Button (a UI Button?), while still holding an input key, the release for that key will be executed.

[undone willow]

I could probably break it up into custom events tbf

I followed a wallrun tutorial that used tick and then I built off of it so it is pretty long atm

[gentle urchin]

Right, but isnt that like the buttons fault ?

[velvet swallow]

I guess, but the button has no code except print String.
So this is some default engine behaviour.

[unborn compass]

So this is an actor i made to show where a projectile/shield will appear, does a line trace for a certain distance based on the ability. I cannot get the rotation correct though. No matter what I do it doesn't update the rotation. I have it OnTick to correct position based on line trace but I cannot get rotation to update correctly. I wanted it to be overwatch style. Apologies for spaghetti code

basically just can't get it to rotate with my pawn but like 200 units in front

[velvet swallow]

You could just make it a Component of your pawn.
Or Attach the Actor to you Pawn, which would make it a Child-Component.
Either way the relative transform should than stay the same in relation to the Pawn

[gentle urchin]

Yes exactly what i was getting at ^^ you can try doing a custom button instead

[maiden wadi]

I strongly recommend learning how the functions TransformLocation TransformRotation, and their InverseTransform counterparts work. They'll help you a ton when learning vector math in Unreal.

[unborn compass]

i'll take a look

[maiden wadi]

Actually I just reread through your logic and I'm not sure you're looking for those in this case, but they're still worth checking out.

[velvet swallow]

Yea, my workaround would be to just not use the release event, when it is not reliable.
Instead just check if the button is pressed on a fixed interval, before hiding the overlay again.
My hope was that I just had to configure something differently tho ^^

[unborn compass]

I want one system for both projectiles and stuff like shields though and for it to take obstacles into account so thats why theres the line trace

[gentle urchin]

Custom button is quite easy to make / set up if you wanna give it a crack. Basically a border, some overrides, dispatchers and pressed state

Not sure it would solve anything 💁‍♂️

[maiden wadi]

@unborn compass Looks like rotation is your only issue. I believe your issue is that you're rotating it based off of world center. I think what you're actually looking to do is rotate it towards the player's camera direction. Or even the trace direction.

[unborn compass]

exactly

[maiden wadi]

You could do something as simple as (TraceEnd - TraceStart)->Normalize->RotationFromXVector

[unborn compass]

that makes sense lemme try

thank you Authaer

[velvet swallow]

I will play around with it, maybe I will take a look at the cpp code for the button and see if there is actually something the triggers the release event.
Thanks tho 😄

[gentle urchin]

That makes more sense obv^^

[maiden wadi]

UserWidgets and controls are a special kind of hell that really sucks if you don't have a decent view of the whole system.

[unborn compass]

its working now but is "fixed" in the wrong way.... how can i rotate it 90 degrees based on characters position?

i didn't pay attention in linear algebra 😦

[maiden wadi]

Try MakeRotFromXZ with X being your TraceEnd-TraceStart->Normalize. and Z being VectorUp. Then break/make it with a + or - 90 on Yaw.

Should be fairly resistant to pitch changes that way.

Something like this.

Er. except +90

[unborn compass]

kk lemme try thank you

[maiden wadi]

The amount of copies BP vector math make sometimes kills me. 😄 I really hope Verse helps with that and will work in UI, that'd be awesome.

[unborn compass]

lol i think it might be a bit more complicated then this

cause the axis it needs to be rotated on is changing?

based on the direction the pawn is looking?

or no should i try adding to X instead of y?

[maiden wadi]

Oh

I did add to pitch. 🤦‍♂️

Meant to do that to Yaw.

[unborn compass]

❤️

k so now it works at eye level, but if i look up it starts twisting

[gentle urchin]

😂

[maiden wadi]

I have no idea.

[gentle urchin]

What about find look at rotation.

Isnt that.. functional?

[unborn compass]

i tried but was probably doing it wrong

[gentle urchin]

You want i facing player ?

[unborn compass]

ye

[gentle urchin]

So findlookat(target location, self location)

Self loc being character i suppose

[gentle urchin]

Screens "forward" is the edge?

[unborn compass]

same issue now though I have to turn it 90 degrees but the 90 degrees needs to be split between whichever vector my character is facing

i think....

[gentle urchin]

So

Find look at

(Target location, target location+character right vector)

Asssuming char forward is always directly towards the 'shield'thingy

[unborn compass]

can you show me in blueprints

srry lol i can't visualize what this means

[gentle urchin]

Findlookat has two inputs

[unborn compass]

oh oh

[gentle urchin]

Start -> Target location
Target -> Target location + GetActorRightVector

It could prob just be self

And self + right vector

Instead of "target"

They'd be the same anyways

Start being 0 and target being right vector...

[gentle urchin]

Not from trace start

[unborn compass]

trace start is at pawn anyway

[gentle urchin]

Either both from trace start, or both from trace end

[unborn compass]

oh

[gentle urchin]

Start can prob just be 0,0,0 vector tbh

[unborn compass]

kind of the same issue as before here. Doesn't work when looking up but at eye level it works

[gentle urchin]

give me a sec

you're right

its nulled

this works

the original transform orientation of the mesh

You could also use a spring arm for this i guess

Already got collision detection on it

And a socket to connect to :)

[unborn compass]

perfect, you're a genius

[gentle urchin]

🥳

[unborn compass]

now i need to be able to rotate it on button press like mei's wall in overwatch

lol

i think i got that on my own though

[gentle urchin]

Springarm, socket, rotation offset

[wicked magnet]

This is such a simple thing, yet for some reason I'm not sure the answer. I want to access my Player Controller to find out which skeletal mesh is being used to play a montage from a component blueprint. I have multiple characters, and so I want to reference the player controller to find out which one to trigger an animation.

I tried this but clearly did not work.

[flint wharf]

I'm adding some blueprints to pan the camera in overhead view using the mouse.. is that supposed to live in the player controller?

[gentle urchin]

Could live in your cameramanager

[odd ember]

camera manger is an extension of player controller

so yeah it doesn't really matter

but generally everything somehow goes through the camera manager

as annoying as that is

[flint wharf]

Thanks... hard to figure out where everything goes looking at toy examples

[cunning heart]

Hey there,
I'm having some Camera jitter issues in my 3rd person project and I was wondering if anyone could help out.
Basically, I’m trying to have the 3rd person player Camera that’s on a Spring Arm to focus on both the player and the locked-on target.
I do that by getting a point between the player and the target and having the Camera look at it using “Find Look at Rotation”.
The logic works as intended but the issue I’m having is that when I move left and right while locked on the camera has a bit of a horizontal jitter.

I've attached an image my logic inside the player blueprint.

And here is the issue in action.
https://www.youtube.com/watch?v=Q5Qk9BxGHv0

[unborn compass]

could someone explain this possibly lol

[cunning heart]

did you try doing it the other way around

pull it from the Bind event and then create a function from that

[unborn compass]

doesn't work either way

oh

ok

[wispy pumice]

Anyone know what would be destroying my player and throwing me into spectator mode when using World Composition?

I'll get so far away from where I spawned at and the vehicle I'm driving and the player just straight dissappear....

[icy dragon]

Sounds like your player is flung by intersecting physics.

[wispy pumice]

It always happens around the same area

[icy dragon]

Either that, or since you mention world composition, the player might falling before the level loads

[wispy pumice]

Wouldn't the camera go with it though?

It vanishes instantly

let me play it again and see

if so then the player should still be in the list

Wait what is this?

I keep seeing it

seems to keep changing location

Default Pawn...

Sounds like it may be the source behind my issue

[icy dragon]

Aha, then that's Game Mode issue.

[wispy pumice]

@icy dragon Well I was doing a possess...I changed the game mode and set my spawn and now I'm spawning in the air nearly a tile away from the spawn point...

[velvet swallow]

Make sure that the Pawn on which you are running this is actually controlled by the AIController.
Also I think you need a working NavMesh for that to work.

[2022.03.17-23.43.33:486][327]LogScript: Warning: Accessed None trying to read property CallFunc_Array_Get_Item_1

Why am I getting this? Does this mean I have a nullptr in the array? It's from a for loop node

[desert juniper]

yes, it means your array is empty (or null), or the element you are trying to access in the array is empty doesn't exist

[pliant salmon]

Get_Item_1 means the 0th item?

or is that the 1st instance of a Array get Item?

[desert juniper]

I believe it means the item in the array position 1, but don't have the soruce code in front of me now. I'd start with validating the array is valid before you loop through it

can you screenie?

[pliant salmon]

sure

[dire frost]

I think it means the thing that's trying to read the array is null

Not sure tho it's been a long time since i moved to cpp

[desert juniper]

you know, it does sound more like the array itself is just null

[dire frost]

Add a breakpoint on the for each loop and see the length of the array

[pliant salmon]

okay, not super used to debugging BP, (I am writing the c++ plugins haha)

let me try

[desert juniper]

@pliant salmon click on the for loop, and hit F9

then play the game

[pliant salmon]

can it debug when in standalone play?

or does it have to be simulate

[desert juniper]

I've not tried to do it on standalone

[dire frost]

No i think it should be in editor

[desert juniper]

yeah, if possible, just run it in the editor

[pliant salmon]

ah yeah the set has 1 element "None"

[dire frost]

Yep that's your problem then

You can add "is valid" macro

[pliant salmon]

on the set?

[dire frost]

On the loop body

[pliant salmon]

right

good idea

thanks @dire frost @desert juniper that sorted out that issue, now onto the next haha

[dire frost]

Lol hey progress is progress

[pliant salmon]

divide by 0, even though I have no division sigh!

very retro error to have

[dire frost]

Did you setup some kind of a nav mesh?

[icy dragon]

Well, at least it didn't open a black hole...

[pliant salmon]

don't give it any ideas @icy dragon

[dire frost]

Oh i thought it was a post process volume

Is your actor moving in the air?

[dire frost]

Doesn't it tell which actor with that warning?

[pliant salmon]

I just find it so bizarre that a GetComponentS() piped to AddItems() would result in a None added to the set

[dire frost]

Yeah move to function does not support air movement

[pliant salmon]

doesn't seem smart

[dire frost]

You should check if the gotten component is != Nullptr

Otherwise it will add null to the list

[pliant salmon]

yeah in another part, but hard to trace down unless it can pin point the node that is buggin

[dire frost]

There's a way to make the moving in functionality yourself with code or you can maybe find a plugin for it

It's a really difficult thing to do but you can make a volume with a bunch of point your actor can move to using an algorithm (A* is a popular one)

[desert juniper]

someone did something for 3d movement that was kinda a neat solution

let me see

[dire frost]

You're checking if 0 is a valid index not the object it self

[pliant salmon]

groan!

[dire frost]

Huh?

[pliant salmon]

so I have to loop through the GetComponents result, check valid and then add to set by hand?

or is there a macro

has to be, seems common enough?

[dire frost]

Yeah it called "is valid"

It should have a question mark thumbnail thingy

[pliant salmon]

ah right so that works on lists too?

[dire frost]

Nope, but you can do an each for loop

[pliant salmon]

okay so I do have to do the loop by hand.

[dire frost]

But i find it so weird how that "get all components of class" returns a nullptr

Don't thing it should do that

[pliant salmon]

I thought BP would be more polished and easier to use imo

like even in python I could do list += some_list_returning_function()

and if the list is [] then it's a noop

not adding a nullptr, if you get what I mean

[dire frost]

Yeah i understand

I thought that function basically does the same thing

But i guess not?

[pliant salmon]

doesn't seem like it because I was getting Nones from the set it seems

although I probably am doing something silly, maybe

[dire frost]

Tbh i never used sets ( i find it kinda intimidating)

Can't you just add arrays to your original array? Does it need to be on separate arrays?

[pliant salmon]

that was my original idea, but then the context menu suggested "add items" which belonged to Sets, and then I thought oh actually a set is what I want (no duplicates)

[desert juniper]

here's the video https://youtu.be/9uU0frKenMs?t=367

[dire frost]

As long as your not using maps the You good

[pliant salmon]

oh wait, the None actually refers to the object i want

[dire frost]

Oh yeah that's pretty much how i did it too

[pliant salmon]

such a weird way of displaying this

[dire frost]

Huh? So it's not s nullptr?

[unborn compass]

real quick anyone, a way to get absolute down vector?

[pliant salmon]

I don't really know what that means (the screenshot)

omg

omg @dire frost

[dire frost]

It means there's two items, first is null and second is a thing

[pliant salmon]

there was a default value item of None

[dire frost]

Omg

I knew there was something off

[pliant salmon]

such a noob haha

[dire frost]

Isn't absolute down vector just an up vector?

[unborn compass]

sorry i probably used absolute wrong

just down vector

straight down

[dire frost]

Nah it's ok. Sometimes you miss these silly thing that could fuck up your whole code

[pliant salmon]

(I was looking at the Default Values in details as the current value of the variable)

I wasn't lying when I said I had no exp debugging BP haha

[dire frost]

(0,0,-1) is a down vector

[pliant salmon]

thanks for your help mate

[trim marsh]

yo guys , i have this variable , and i need to get the value only 1 time , the problem is that this function is on tick event , any sugest?

[dire frost]

Np 👍. And enjoy bps because they are way better than cpp lol

[desert juniper]

have it on tick, and just turn tick on/off whenever you need?

[dire frost]

The whole engine would've crashed for the same error lol

[pliant salmon]

hahaha do you think so? I have found UE c++ quite easy

oh segfault crash, yeah I get what you mean

[dire frost]

You can use a do once node

[trim marsh]

need tick on all the time

[manic viper]

I am having the darndest time figuring this out.

I'm trying to get a Cannon Actor to launch a projectile when the player presses "E"

I tried creating an event dispatcher on the cannon and triggering it from the player BP but I think i'm doing something wrong here. I'm sure it's something simple that I'm missing.

(is this even the best practice for accomplishing this ? )

Here's the Cannon bp https://i.imgur.com/oWjpEm4.png

and the player bp trying to call it

https://i.imgur.com/UnZ9h2F.png

[desert juniper]

then yeah, like @dire frost said, use a DoOnce?

[dire frost]

Honestly i kinda prefer c++. Cause it's way more manageable than the literal spaghetti code of bps

[pliant salmon]

I could see with the 👀 that the TSet<Blah> = {nullptr} if it was code haha

[icy dragon]

The other way of saying C++ can have spaghetti but not in your face

[trim marsh]

yeah , it work thx

[thorny lily]

Hey guys, I currently have the rotation problem, where the turret i rotate goes the long way around when hitting the -180 to 180 point, and i cant wrap my head around it atm.

[icy dragon]

That's gimbal lock issue with FRotator struct.

[dire frost]

So what's the problem?

[manic viper]

sorry! It doesn't work at all

[dire frost]

It kinda seems fine to me

[manic viper]

that's what I thought

LOL but when I press E nothing happens

[manic viper]

The intended behavior is i press "E" and it spawns the projectile and launches out of the cannon. I know that the projectile spawning works because if i attach the spawn actor directly to beginplay it will launch one right at the start

I think it has something to do with how i'm referencing ?

[dire frost]

I'm looking at you code and the only thing that seems to be a possible problem is maybe you not setting up the interface correctly?

[manic viper]

https://i.imgur.com/QhPAlkl.png

[dire frost]

Oh yep that's the problem

It's doesnt know which cannon you are reffering to

[dire frost]

How do you interact with the cannon tho?

[manic viper]

its just a cannon in the level

lol

[dire frost]

Yeah but how do you interact

Do you look at it and then press E?

[manic viper]

you don't i'm trying to test something completely unrelated, but I need to get the absolute ground floor basics of "the cannon shoots when I press this button"

[dire frost]

Or is it something that you can always use no matter what

[manic viper]

always use no matter what

it's literally just a cannon model sitting on the ground with a projectile spawner on it

[dire frost]

Then set a hard reference to that cannon

You can set it manually or user "get actor of class"

[dire frost]

Btw unless you will possess the cannon, you won't need it to be a pawn

[manic viper]

eventually it's going to move and rotate

[dire frost]

Oh ok then that makes sense

Btw did that fix the problem?

[manic viper]

just tested

ABSOLUTELY

just hard coded it in LOL

legendary

Thank you Iskander!

[dire frost]

Lol well it is a fix

[manic viper]

i know it's not the best practice. but I just want to see what i can get away with for now as I'm learning

[dire frost]

You can probably use line trace to and cast the hit actor to the canon pawn and fire the fire interface from the cast

That's how it usually works

[dire frost]

After all FRotator is just a struct of floats and you should treat as one

[manic viper]

Haha so it's gotta work with a projectile

for reference, the "intended" gameplay is gonna be to rotate the cannon and adjust velocity of the projectile to hit certain objects

you will essentially be controlling the cannon

[dire frost]

In other words, possessing it

[manic viper]

👀

...yes

should i ... put all the logic .. on the cannon ?

😮

[dire frost]

I mean, yeah why not

It's already a pawn so you might as well

Makes your code more readable

[manic viper]

Yeah I think you're right

[unborn compass]

how to get actors who are overlapping w/ a component? can't remember the node ffs

collision capsule

does getOverlappingActors work? lol

[dire frost]

Yep

[wispy pumice]

I can't figure this out for the life of me, could someone please give me a helping hand on this? https://youtu.be/SCt9WoIA0n0

I keep despawning and I don't know why.

[faint pasture]

Put Cannon logic on the cannon. That's kinda the whole point of object oriented programming.

What's the gameplay, are you always controlling the cannon or is it a thing on a ship or a station you run up to and control or what

[pliant salmon]

also makes me a bit sad when the function you need isn't exposed to BP

why isn't FRotator::Clamp() exposed?

[faint pasture]

What function

[dire frost]

Usually it's just unreal Devs forgetting to expose something to bps

[faint pasture]

Is this for some wild 6DOF stuff or something that'll work in Euler angles?

[dire frost]

Oops tried to reply to the other guy lol

[pliant salmon]

nay, no 6DoF (hello again), this is simply I want 0-360 deg value

[faint pasture]

Btw a BP function library is a GREAT first c++ project. Make it.

[faint pasture]

Ah so converting 1080 to 360. Just modulo it

[pliant salmon]

Ohhhh my friend I already have a lib, so I'll expose it that way

[faint pasture]

If it's just a simple clamp or modulo on one axis then you can just do it in BP in 2 seconds.

[pliant salmon]

probably find it's in UE5 haha

[faint pasture]

A clamp on a rotator would be a bit more exotic.

[pliant salmon]

yeah it is, but it's also negative for some reason

[faint pasture]

Negative is fine. What are you trying to do?

[dire frost]

Maybe yeah, wouldnt be surprised if that happens

[pliant salmon]

convert actor rotation yaw to Heading (0-360deg)

[faint pasture]

Is this for display? Like you're done treating it as a rotator and wanna display it somehow.

[pliant salmon]

somewhat yes

simulated AIS broadcast

[dire frost]

I'm sorry, what are you trying to do again?

[pliant salmon]

boat simulation

[faint pasture]

Heading = (yaw + 360)%360

[pliant salmon]

AIS being one of the "sensors"

[dire frost]

I don't know much sbout boats but i think you can Work it out

[pliant salmon]

yep nearly done, just debugging this

[faint pasture]

Try what I just posted

[thorny lily]

Okay I am really stuck on this rotation error with my tank turret,
I use the camera to calc in which direction the turret moves by getting the difference between their rotations to limit the speed the turret turns.
And the camera rotation goes from 180 to -180 which causes the problem but i dont find a workaround rn

[dire frost]

Trying lerping the difference instead of the tank rotation?

[pliant salmon]

thanks mate. I know it's not hard, I just like to use functions if they are already there instead of filling my BP with maths 😉

[dire frost]

Like get the difference between the tank and the camera and slowly add that to the tank rotation

[pliant salmon]

this looks cool

[faint pasture]

@thorny lily can't see your video but each frame, calculate a Target rotation and continuously lerp towards that

Input drives target rotation

Target drives the interp

Interp drives the turret rotation

That's how you can enforce a speed limit

[thorny lily]

i thaugt learping doesnt really make sense as the turret needs a fixed max rotation speed and learping would be pretty inacurate as it would need the same time to go from 0 to 90 degree as from 0 to 45 degree or am i wrong? 🤔

But yeah what u just said sounds good, I'm gonna try it out^^

[thorny lily]

thanks^^

[dire frost]

Yeah you're right but i just wanted to avoid a more complex way to smoothly change a value

I can tell how it works if you want to

[faint pasture]

Rinterp to constant

It is exactly a speed limit on a rotator

[dire frost]

Completely forgot about that lol. Yeah that can work too

If i remembered that node was a think i wouldn't have made myself from scratch

[thorny lily]

gonna try that not exactly sure yet how i should calculate the interp speed to get a fixed speed limit but we will see 😄

[dire frost]

If we're assuming that moving 20° should take 1 second then Just get the different and divide it by 20

So if the difference is 60° the will take 3 seconds to reach that

[thorny lily]

thanks guys that really seems to solve my problem completely and at the same time makes my calc shorter on the tick

[pliant salmon]

are the tracing/statistic stuff exposed to BP?

[dire frost]

Not sure what're referring to

I mean i should be asleep 5 hours ago but i cant

Insomnia is a bitxh

[pliant salmon]

for performance monitoring etc

profiling etc

https://docs.unrealengine.com/4.27/en-US/TestingAndOptimization/PerformanceAndProfiling/

[dire frost]

Oh yeah they are

It actually tell how much performance each node is taking up

[pliant salmon]

and making my own?

[manic viper]

Sorry I missed this! I was knee deep in blue prints!

Right now I'm just trying to setup the logic to "control" the cannon I just put it all on the actual cannon as a pawn with a camera now

now I have to dig into the documentation and learn about collisions lol

https://dl.dropboxusercontent.com/s/d2dmns45zlc0bo5/NVIDIA_Share_i9tA7Mf6qL.mp4

I have the barebones basics functionality setup. With the logic on the cannon - setting up construction script in the projectile to adjust the velocity

(full disclosure I am an absolutely novice programmer. I do 3d modeling and voice acting. So this is all new to me. I apologize in advance if i ask something stupid)

[dire frost]

Can you take a screenshot of the errors?

[manic viper]

yeah it's just one error

just repeated for every instance that it spawns

something about simulate physics + collision incompatability

[dire frost]

Nah it's alright mate, we're all stupid deep inside

[manic viper]

haha if yall ever need help with audio engineering, you just ping me!

or sound design

[dire frost]

Thanks i will keep that in mind

[pliant salmon]

also, please tell me there's an easy way to get degrees from the 2d unit vector

I have atan already but that whines about divide by 0

[dire frost]

So the collision is not set for the projectiles. You can enable it by using "set collision enabled"

[dire frost]

Honestly i wouldn't pay too much attention to that warning

[dire frost]

You can enable it in the details panel of the projectile or in construction script (again using the set collision mode enabled node)

hmmm

this is what is under collision on the collision component

had to change it under collision presets there's another drop down. Physics (and query)

[mystic bough]

hey all. I'm looking into the best way to store my player's cleared levels. I was considering doing a struct that would also reference their data table row where all info was pulled from, but wanted to consider other options. In theory, 100+ levels and there's additional challenges that can be added to levels.

[late shuttle]

Just make a data table and keep them organized with a Name variable.

Super easy.

[mystic bough]

struct was so I could store the additional challenges info with the stage, left out that part

[odd ember]

can't write to data tables

[pliant salmon]

I have an instance of a class (that is a subclass) as a variable in a blueprint, and then I passing this instance as a pointer to some c++ code, and this is saying that this point !IsValid

what can cause this?

do I have to do something special to this instance/variable to "initialise it"

[odd ember]

??? are you using reflection to get BP values that you modify in cpp?

[pliant salmon]

nope

[odd ember]

so how can you get a BP variable in cpp?

[odd ember]

is it a cpp variable that you have exposed to bp?

[pliant salmon]

oh sorry, if by reflection you mean BP exposed, yes

[odd ember]

no reflection is something else

[odd ember]

this is a function with a parameter, not a variable?

[pliant salmon]

correct

AISPositionReport is a subclass of GenericMsg

but otherwise this seems fairly pedestrian, no?

[odd ember]

I can't see the full code and where the struct connects

is the struct BP or cpp based?

[pliant salmon]

cpp

[odd ember]

where does it connect from?

looks like a #cpp question

[pliant salmon]

yeah I reckon so

[odd ember]

then why post in #blueprint lol

[pliant salmon]

because I have been doing this stuff in cpp with no problem?

the minute it's in BP it doesn't work

mainly the instance AIS Msg Wrapper

[odd ember]

cpp transitioning into bp is still #cpp

[pliant salmon]

I was wondering if i had to do something else in BP land, is all

[odd ember]

can't tell from the info. but if you're posting code here it's #cpp all the same

[pliant salmon]

fair enough

[opaque river]

I have something that should be, and likely is, straight forward but my methodology is flawed. I have a component I want it to rotate in a set circle around the actor at a given radius, the movement is supposed to follow an analog stick movement and basically to remain in a position until that stick is moved But I can only Get it to move to one of the set up down left or right instead of smoothing the movement

what method should i be using to have the movement mapped to the stick movement to get as close to 360 degree movement as possible

[faint pasture]

Show your setup

[opaque river]

I made some headway but now slightly different issue

very simple follow the leader

So we have our little aim assist which follows around our arrow

we rotate our arrow via its pitch following our gamepad movement

so now we have 360 degree motion

but the issue needing to be solved is it snaps back to default position when we stop applying directional pressure

where I would prefer it holds the last position

trying to resolve that now

[trim matrix]

You need to add a small amount of rotation each tick.

As of now, you are basically just setting the relative rotation based on the axis value.

[opaque river]

well i want it to be effectively an aim reticle and retain its position think like twin sticks shooter

[trim matrix]

As you probably already know, when you hold the controller stick all the way right, axis value = 1. When you let go of the controller stick, axis value goes back down to 0.

[opaque river]

not with the Yaw

yaw is 180 to -180

oh i see

[trim matrix]

I see, then just replace the 1 with 180

Same issue

[opaque river]

im with you, i was just jumping on that as i just solved the -1 to 1 range was limiting the movement

[trim matrix]

What you need todo is.

Get relative rotation

• some value

= new relative rotation

[opaque river]

wont that same situation just be the same delio with extra rotations?

[trim matrix]

No

SomeValue can be based of the AxisValue

If you use this method

Each tick

When this math gets calculated

Even if the axis value = 0

The new relative rotation will not change.

Because the formula is GetRelativeRot + SomeValue(BasedOfAxisV) = NewRelativeRot

This will create the behavior you are looking for.

And btw SomeValue is just a rate of change

[opaque river]

well the way its currently working you have the pitch, our pitch is being rotated 360 atm its following the movement of the axis yaw as a slave component, if we were to say we have some other modifier and we are adding or subtracting or multiplying by our axis yaw that number is being updated instantly with or without input
so as soon as we touch it or let it default back its updating and thus changing the pitch

so if we say we have some X which we are adding the yaw to. X + (int from 180 to -180) that value is still being modified at the same rate as our method from before, assuming we have it set to move perfectly in sync with our controllers yaw position

[trim matrix]

Im not sure what your saying. Your issue is incredibly simple to solve. I hope I helped and good luck with it.

[opaque river]

yeah well thanks for trying i probably just need to come back with fresh eyes like a piece of writing you have spent too long staring at

[manic viper]

holy moly i just made the most cursed "While Key Down" implementation

[gentle urchin]

Oh lord

This doesnt even workn

Its basically just a do once event .. just like a regular input action is

[manic viper]

oh no

it works

does it look good ? Not at all. Is it viable for a finished product ? Never.

[gentle urchin]

How does it work?

It really shouldnt

Oh nvm

[manic viper]

that's what makes it beautiful

[gentle urchin]

The return from delay

[manic viper]

LOL yes

[gentle urchin]

Didnt see it in that hurdle 😄

[manic viper]

a 0.1 tick event

[gentle urchin]

0.5 on the screenshot

[manic viper]

yeah i dropped them all to 0.1

https://dl.dropboxusercontent.com/s/9by0k6dpwe5gnmo/UnrealEditor_PysZix8ypC.mp4

[gentle urchin]

Might just start a timer at that point 😂

[manic viper]

still looks TERRIBLE

i was doing my best to avoid putting it on the event tick

[gentle urchin]

Anim is ment for tick

[manic viper]

because the log itself for turning and rotating is so convoluted

[gentle urchin]

They're brothers in arms

If you go to 0.033 itll look fine

😅

[manic viper]

🤔

[gentle urchin]

Atleast 30 updates per sec

But still would just use tick really

[manic viper]

it looks REAL janky LOl

it definitely looks "smoother"

but also not

lol

[gentle urchin]

Well

Higher update time

Without considering delta for rotation

[manic viper]

I know there are much better ways to handle this. I'm just trying to brute force my way into it while i'm learning unreal lol

[gentle urchin]

Makes it look better but still bad 😄

Rotationspeed = rotationrate * frame Delta

[manic viper]

i have one of these for each key press LOL

[gentle urchin]

Rotating 45 degrees in a snap will look bad even at 1000 fps

[manic viper]

its ... something

[gentle urchin]

Ouf....

[manic viper]

im VERY new

[gentle urchin]

Creative i suppose 😄

[manic viper]

im just trying to think of the "best" way to approach what i'm going for here

i want to be able to walk up to the cannon and aim it by pressing control buttons

like there will be a wwheel to turn it left and right and another one to aim it up and down

and another for velocity

[gentle urchin]

Tick is tha way

Enable tick when you get up to it

Disable it when you leave it

Tick, target rotation and RInterpConst

[manic viper]

🤔

how do i put all 4 of these on tick!

https://i.imgur.com/aEWf7cg.png

lol

[gentle urchin]

You only need one on tick

The RInterpConst

The input that you want constantly triggered sounds like something that would be an axis input and not action input

[manic viper]

ill have to watch wadstein video

There isn't one for Const

only the og Rinterp

D:

[manic viper]

Yeah I loaded it up and looked it up

im just at that stage where this is basically wizardry

[gentle urchin]

It moves from one rot to target rot at fixed speed

[manic viper]

yeah i got that part. I but knowing how to create the target rot in the way that I want it to work

[gentle urchin]

The inputs would only affect target Rotation variable

[manic viper]

basically, I'm learning to drive and you just handed me the keys to the mclaren

[gentle urchin]

Tick would handle rotating

So instead of set rotation you set the target rotation

[manic viper]

🤔

oh i think that actually makes sense

[gentle urchin]

The input on the function should probably be a rotator aswell

[manic viper]

but i'd still have to do that for each "axis" essentially yeah ?

[gentle urchin]

Yeah , for sure

You could do a bunch of bools

[manic viper]

so many bools

[gentle urchin]

And let tick update it according to currently active inputs

Only 4 :p

[manic viper]

So many

[gentle urchin]

Or floats

[manic viper]

you're out of control, squize. Breaking my brain

im 100% going to try and mess with this tomorrow after I get up

@manic viper pinging myself to find this location later

[gentle urchin]

At that point just doing the rot input directly could be cleaner depending on desired effect

[grand briar]

Need some help coming up with a better solution for.. well i'm rotating my actor based on the angle im looking at. So i can look 90 degrees to the left before he starts rotating that direction

Example

Here's what i came up with. I think it counts as cursed

The flip flops seems to be causing a lot of lag in the rotation

[gentle urchin]

Is this on tick

[grand briar]

Yeah

[gentle urchin]

Ouff

[grand briar]

I lack better knowledge

[gentle urchin]

You wanna update the headrot on tick, and check for the dot product of aim vs char forward

Its ok

I judge, but i mean nothing by it 😆

Dot prod of <=0 is 90 degrees so thats what you wanna react to

Flipflops is a bit unpractical for this

Since they effectively run at half tick rate

Making it jitter

[grand briar]

Yeah and i got two of them there, i can notice when i PIE and watch it, it becomes really obvious how slow it is after the second one

But i'm still not clear what to do? I am doing the headrot on tick. I figured that's pretty much what i'm doing.. what you said

[gentle urchin]

If standing still then if lookatdirection dot actorforward <= 0, update actor untill actor forward == lookatdirection

[maiden wadi]

On a side note, this is usually animation driven via a 2D aimspace. Epic has a decent implementation for it in their content examples.

[gentle urchin]

In a while i can setup some nodes in a bp 😄

True that^ i always forget that , cuz i never do it 😅

[grand briar]

But i also have conditions, such as it has to finish rotating to that point before it can rotate again. So i set the turning bool there also need to switch the use controller desired rotation otherwise i cant run around again

[grand briar]

Oh? That'd be really helpful. Do you know which one?

[maiden wadi]

Not sure, can look in a minute.

[gentle urchin]

Yes, you'd toggle it off again when the aimdirection is equal to actor forward ^^

[grand briar]

Ah, yeah i hear what you're saying. But.. i still don't see a difference from what i'm doing, even thought i know what i have now is wrong hah. Been trying to set this up for two days now, my brain is a little fried. I didn't want to tick the bools either i don't know if that's wrong. Setting it to true every frame

Oh, and i had a big problem with the actor rotation vs the control rotation. They don't match so not sure if the dot would work here. Figured out that they're different ranges, actor rot has a range from -180 to 180 and control rot 0-360. I had to convert their range with some.. probably also less than ideal maths so that i could stop rotating when they're nearly equal

[gentle urchin]

Just add 180 to actor rot and they're very comparable

You dont need the map to range

[grand briar]

Damn.. yup..

[grave relic]

Quick question, can you not have actor variables in data tables?

[gentle urchin]

you can have variables

[grave relic]

Yeah but when i make the variable type actor its greyed out

[gentle urchin]

you cant have instanced object references

it's static data

[grave relic]

👍

[gentle urchin]

you can have an actor class if you want

[gentle urchin]

did you try with a spring arm ? 😄

This is what it would look like 😛

[dreamy yacht]

Hi, I have a similar problem. I am working on arcade racer, but my cars tend to roll over constantly ruining the gameplay fluency. Adding the inertia to axis kills the steering responsiveness and cause weird behaviour. I have decided, that it would be best to limit car rotation to smth as -45/+45 in Y axis ( X axis in my case ) to prevent it from flipping on the roof, but the code I have made doesn't work

This is code inside the vehicle BP

[solid delta]

How can i add collision for spline blueprint ?

i made wires with spline blue print

[white elbow]

how do I make a line trace ignore the whole class of actors instead of specific ones?

2 classes to be precise

[gentle urchin]

Change the class' collision response

[glossy trench]

Good day,

is the gamepad "A" button (xbox 360 gpad) HARDcoded in the widgets to make "A" button ,,, the confirm/click/pressed ?

how would i "switch" it to "B" button? (make B button the "confirm" one) ?

[lapis inlet]

Anyone willing to guide me in creating a basic gravity simulation?

[gentle urchin]

Not using the built in one?

I believe you must make your own CMC for it tho

[haughty temple]

are you not able to delete all array elements in a loop? print string tells me its reading both attached actors but only destroys 1
edit: i found a workaround just set the life span of the actors to .1 and it works not sure why it wont work with destroy actor

[lapis inlet]

As in, objects emit their own gravity based on parameters like mass, density and radius etc etf

And on a 2d plane

[gentle urchin]

reverse loop when deleting , if you're removing entries aswell

[dreamy yacht]

hi! anyone can help me with setrelative rotation ( above) ?

[tight pollen]

how can i check what Tick

in blueprints

[solid delta]

guys how do i add colision to my blueprints spline

[maiden wadi]

Not at the pc at the moment to look but chances are it would be a project setting or coded in Slate. In like UButton or a parent.

Er SButton

[pastel rivet]

Hmm weird issue, but i have a print string on event tick, and there are several instances of the same blueprint when playing, printing different results from a variable, even tough theres only 1 instance of that BP

[solid delta]

Halp lmao

[gentle urchin]

sorta contraticting statement

[pastel rivet]

Hey, what if this was a growing group? Etc my last group was 1-9 (0 to 8) but now theres a new group 10-18 (9 - 17)

[pastel rivet]

Yes ikr, but its weird, there are 4 instances printing in my log, and giving different results, but theres only 1 BP in the world

[gentle urchin]

the / would be on group amount while % would be on channel amount

if you wanted a dynamic group i'd suggest doing an array

[gentle urchin]

Array of "group members"

Donno how you handle sending the int, but whatever is sending the value would also have to know about the amount of group members for this to work i suppose

[pastel rivet]

Basically i have everything i need then

[gentle urchin]

AmountofChannels = Channels * groupmembers

[haughty temple]

ahh perfect thank you 😄

[gilded hazel]

anybody know how i can set up aiming towards mouse cursor location in 2d? struggling for tutorials or resources and everything ive tried doesnt work.

(id like to aim up etc)

[gentle urchin]

Doesnt world location work?

[gilded hazel]

full rotation basically

[gentle urchin]

Deproject mouse to world ,

Using X and Z values

Or Y and Z , depending on your forward ofc

[gilded hazel]

im not familiar with deproject to be honest

[gentle urchin]

Aim direction being findlookat with a nulled out depth axis

Deproject screen to world takes the mouse screen location and finds the world location under it basically

[gilded hazel]

ah

er

ill be honest ive no idea what half of that means 😂

[hallow compass]

I’m trying to make a loading screen using the Load Stream Level node, everything works fine but all the textures don’t load until a few seconds after the rest of the game actually loads. Any way to make an actual loading screen out there?

[gentle urchin]

Mouse has a location on the screen
Deprojecting takes this screenlocation and i assume traces directly behind it
Then it returns the location where the trace hits in the world

This location will be a Vector(x,y,z)

Since you're on a sidescroller you only have 2 axis to care about. Right, and up

So you want to take this location vector and null out the axis you're not using (your depth)

[gentle urchin]

C++

[stuck plaza]

is it possible to find by predicate from TArray<> in bp?

[hallow compass]

Scary

[earnest tangle]

No

[gilded hazel]

thank you - is this not just a line trace in different manner? does convertmousepositiontoworldspace also work similarly?

[earnest tangle]

On second thought, I think if you create a custom search by delegate function, which takes a value-returning dynamic delegate as a parameter you could use that... but the performance is probably not very good, so it would be fairly limited in its usage

[gentle urchin]

Perhaps thats the node im thinking about tbh

[gilded hazel]

ah

[stuck plaza]

I just used a regular for loop, it seems to work

[earnest tangle]

Yeah that's the way to go in BP's I guess :D

[gilded hazel]

how do you then alter the projectile direction? im using an arrow component on my mesh as the spawn location but i dont know how to set projectile trajectory

so even if i have mouse location i arent sure how to hook that into trajectory

[earnest tangle]

This depends on how you're moving your projectile. You can either rotate it towards that point if it always moves forwards, or if not, set its velocity so that it moves towards that direction

[gilded hazel]

assume you mean rotate the spawn 'arrow'

[earnest tangle]

Depends on how you're setting the rotation of your projectile I guess

You certainly could rotate the arrow component if you're setting the rotation based on it, but it would probably be easier to just adjust the rotation separate from the arrow

[thin panther]

Once you get the vector to look at, you can move by that vector each time

Alternatively if you cant find the nodes for it there is some manual vector math you could do, but im pretty sure the nodes exist

[earnest tangle]

Projectile Movement Component also exists :)

(But you'd still need to figure out the direction for it to go where you want)

[gilded hazel]

yeah i am using projectile movement component

[thin panther]

And the direction you can get by getting the vector it takes to look at mouse position from the arrow

[gilded hazel]

i think the worst thing about learning bp is having 60% of the knowledge and theory but the constant frustration of not knowing how to set things up 😂

[earnest tangle]

that's how it goes lol

?

am asking this question lol

[white elbow]

How would you make a line trace apply impulse to an object as if it was hit by a projectile?

[earnest tangle]

calculate the direction of the line trace, apply impulse into that direction

assuming that's how you want it to work

[white elbow]

kinda, but it wouldn't matter where you hit the component, if it's the same angle it's gonna affect it the same

I want like if you hit a cube way off center it's gonna apply rotational force

if that's even possible

like apply impulse to a point of contact instead of a whole component

[faint pasture]

Isn't there an apply impulse at location?

[white elbow]

🙏 😌 my hero

those default cubes won't know what hit 'em

[modest gulch]

Hello, I want to make screen effect (as in, in-game smartphone or tv screen or whatever having screen with something arbitrary on it), but I dont even know how it is called, so I have hard time googling it for tutorials etc. Only thing I know it is something to do with render targets.

[earnest tangle]

It kinda depends on how exactly you want it to work, but one way to do it would be to just use a Widget Component

You can use it to render a UMG widget which could be used as your screen contents

[modest gulch]

You mean, you can use widget on mesh surface?

[earnest tangle]

the widget component will just render the widget as a flat plane, so if you line it up with your mesh it would probably work

if your screen is not flat then you might need to do something more elaborate :)

[modest gulch]

I will look into it, thanks

[quiet stag]

hey guys im working on a fan made pokemon game just started..was wondering if i should use a data asset for each pokemon or a struct or a data table..not sure what to use

[dark crow]

Data Asset sounds comfy

[gentle urchin]

Isnt data assets not instanciated ?

So DA_A referenced by PokemonA and PokemonB would be the very same data asset?

[last abyss]

yeah

[odd ember]

postprocess?

[gentle urchin]

Sounds like i should've gone for data asset instead of database for my project then

[dark crow]

I think Primary DAs have inheritance

Not normal DAs

[quiet stag]

what about using a data table so i can have a list of 151 pokemon

[odd ember]

that would work right up until the point where nintendo sends a C&D letter

[quiet stag]

thats okay...

im fine with that lol

just kidding im just doing it for me and my friends.

[quiet stag]

so what are the pros and cons of a data table for this

[odd ember]

the pros are

you have a data table

the cons are, you can't write to a data table at runtime

[quiet stag]

kk thanks!

[odd ember]

but if you're just loading in static data

it's fine

[quiet stag]

yep ok great thanks!

[gentle urchin]

For pokemon i would think you'd have 2 datatables

one for the pokemon

[quiet stag]

one for items

[gentle urchin]

and one for the TM's

[quiet stag]

yep

[odd ember]

pokemans

[gentle urchin]

sure, another for items i guess

[odd ember]

I never played pokemon so I'm not sure what TM is

[quiet stag]

trainer moves

[odd ember]

datatables aren't true data bases however so you can't really cross reference them

[quiet stag]

i think or trained moves

[gentle urchin]

basically an action or an ability

[odd ember]

isn't that a part of the pokeman itself?

[gentle urchin]

well partly

but not directly

[dreamy yacht]

do you know how can I limit the car rotation on certain axis ?

[quiet stag]

a tm is an item that you can give to your pokemon to learn the move

[dreamy yacht]

to prevent roll over ?

[gentle urchin]

a pokemon's nature would in the broad strokes define the actions/abilities avaliable to it

[odd ember]

that sounds like a function

[odd ember]

yeah but a pokeman class can contain its own evolutions too

[gentle urchin]

add roll force

[odd ember]

you don't need a table for that

[quiet stag]

omfg guys! haha i can use the pokie api website and just loop through the json and store all that in my data table...what a god move

[gentle urchin]

It can, for sure

[odd ember]

you could even inherit from a base pokeman class and have each evolution as a subclass

[quiet stag]

https://pokeapi.co

im going to look into how i can make an api call and store that in a cvi file

i know how to work with apis and json...just gott figure out how i can store that data in a cvi file

[odd ember]

you can probably do that through a URL command inside of UE

might supercede having a data table whatsoever

[gentle urchin]

Sounds like a lot of work compared to a database

Datatable*

[odd ember]

https://tenor.com/view/cartoon-what-question-mark-question-gif-10681242

they don't do the same thing

you need to store functionality somewhere

data tables only contain data

and subclassing it would be more elegant than e.g. having to use an enum state for each pokeman

[gentle urchin]

Not sure youd say that after 750 entries but who knows

Maybe its just me prefering excel autofill

[odd ember]

you do understand you don't have a choice right? if each pokeman has unique functionality or abilities you still need to write that functionality somewhere

[gentle urchin]

The only difference between them are currently taught moves, a random extra stat

True, abilities would live in their own db

And youd need a class to actually pull and act on that data

[odd ember]

a data table does not make functionality happen

it just stores data

[gentle urchin]

Yes

hence the class to pull/act/functionally use the data

It would need to be separate anyways

due to the nature of the spells

[odd ember]

unless I am mistaken each pokeman has a set of moves that is unique

[gentle urchin]

they're not unique

[odd ember]

in that case I'd consider components

a datatable still does nothing

[gentle urchin]

Indeed, it does not

[odd ember]

and you'd still need to have however many different abilities as separate components

[gentle urchin]

They're not unique in that regard really

there's a limited amount of effects

[odd ember]

that would be the most elegant way of retaining logic while keeping the correct architecture

[gentle urchin]

the rest is just dmg , a particle and some anim

[odd ember]

I mean if it's just damage and effects then yes it's just data

[gentle urchin]

the dmg has affinity, but it acts all the same

[odd ember]

but if it's unique functionality it's different

[gentle urchin]

like, "psychic" and "fire" damage

[odd ember]

that's just damage type

[gentle urchin]

exactly

[odd ember]

tbh sounds like you don't even need abilities just base damage and attack

[gentle urchin]

More or less

[odd ember]

ah no

[gentle urchin]

you'd need something to apply status aswell

sleep/confuse

[odd ember]

there are defensive abilities too

[gentle urchin]

but that could just be a tag

true, harden and whatnot

but thats just another status

[odd ember]

so you would need a minimum of one component per type

with possible subtypes

[gentle urchin]

Yes

exactly

[odd ember]

well that's still logic though

[gentle urchin]

Yepp, but very limited

only need a few of them, which can handle getting passed in some DB row reference

or be spawned based on the row or smth

shouldnt be that hard to bind them together

[odd ember]

and since you can't cross reference data tables (or maybe you can with composite data tables, never tried) you'd probably want this stored on the class itself, and not in a data table

[gentle urchin]

so much more trouble doing it per class really

[quiet stag]

whats that!?

[gentle urchin]

Just part of a TM list

[quiet stag]

ah gotcha

[odd ember]

not really, you just add the component type you need per class

you still need 1 class per pokeman

[undone willow]

what am I meant to plug into input here?

[odd ember]

you're not going to get around that

[gentle urchin]

but you make and manage 150 classes ...

[odd ember]

yes because there is no other way

[gentle urchin]

I'd make 1 "poke"-class , the number of effect classes needed (10-20, tops)

[odd ember]

in the end even with data you need something to spawn in the world

[gentle urchin]

The "poke" class !

Area spawner would have an array of ID's (row references) for which it can spawn

on battle enter -> Spawn "Poke" class with the Row reference-> Class handles pulling the data, swapping meshes, and updating animations

[odd ember]

sure, assuming each pokeman is compatible with the template

[gentle urchin]

For sure

and they would be

"you" made the template

[odd ember]

well no it's not a given

not all of them could use character movement for instance

and you'd need at least 1 animBP per skeleton, still

[gentle urchin]

The animBP would be more troublesome, if its a 3d game

most of the pokemon games are 2d , but not sure what's desired in this remake thingy ^^

[twilit lion]

Please vote so this can be fixed, thank you 🙂
https://issues.unrealengine.com/issue/UE-146356

[odd ember]

even with 2d you'd need the same though

[gentle urchin]

There's no animation there

no skeletals

just a 2d flipbook

[odd ember]

you still need to connect the frames correctly no? so animations can happen in succession

and the sprite sheets would depend heavily on the size of the pokeman

[gentle urchin]

Actually, if its a 2d one, there's no animation at all

its just a sprite

when attacking, they simply "slide" the sprite a bit forward and backward xD

[odd ember]

moving from one sprite to the next is still an animation no? so if you need a sequence of animations you'd still need to connect multiple sprite sheets? or multiple elements of sprite sheets

[earnest tangle]

That has a resolution of "By Design" so I don't think that's getting changed 🤔

[odd ember]

relative rotation?

otherwise use add rotation perhaps?

[gentle urchin]

like this is an "attack" .. the pokemon doesnt animate at all on any level (weirdly enough, they are 2 "animating image sprites in the menu, but here they are just 1 static image)

Anyhow derailing blueprint at this point

Gotta give data assets a dive and see if they're usefull in my project! Think i wanna go more component driven for the construction part of the game aswell,

it seem more reasonable

instead of this massive DB handling everything

even for things that do not have it

[faint pasture]

I would do Pokemon as raw data only. That is how they did the original games and it's not like any of the moves can't be expressed as raw data

You could easily roll an entire Pokemon up into a set of structs

[odd ember]

my point is just that "data driven" often forgets that you have to setup logic for this somewhere

[faint pasture]

But don't make a fan game. Horrible idea.

[odd ember]

and that logic often isn't compatible with how the data is stored

[gentle urchin]

Valid point for sure

[odd ember]

which is why stuff like data assets exist

that can handle data AND logic

[gentle urchin]

I've sorta encountered this exactly , in some sense atleast

my DB coming short of what i need

despite having "everything"

[faint pasture]

You would have to have something along the spectrum towards ECS on the brain to get a data driven Pokemon running well.

[gentle urchin]

it doesnt.. work well enough 😛

We are at a point of having to choose data tables or assets for our tile maps. What's the first thing that pops in your head for a system that supports a tile map editor (not necessarily in game but at least in the unreal editor)?

Basically we need to be able to very quickly author and view hundreds of small tile maps (just a structure really).

[odd ember]

it sounds like tiles should be data only, but that they could contain objects with logic on top of them potentially? so e.g. a trap would still be an object on top of the tile, even if it's a pitfall trap

but that depends heavily on what kind of game you're making

[faint pasture]

Yeah they're data only. It's a procedural system that uses authored maps

WFC specifically

[odd ember]

I have a profound dislike for WFC because it's not directed enough

[faint pasture]

The dream is to be able to paint tiles in an editor mode, just with tile picker and mouse dragging. I've investigated a custom editor mode but it gets a bit gnarly fast.

[odd ember]

you could do something like that in a blutility, but yeah it's not pretty

my biggest problem with stuff like this is that there is no way in blutilities to understand focus, which is fundamental for using stuff like hotkeys

[faint pasture]

Can a Blutility do cursor tracing stuff? I was under the impression that they were just a thing that you "run"

[odd ember]

yep it's just a script

in my case I've been using editor widgets

but again, same problem

so I do have some scripts that allow viewport handling of actors

but it gets finicky because you still have to press buttons on the widget while the viewport has focus

so you gotta use some "hacks" to stop the behavior

like right now I have a timer that runs functionality on actors only while they are selected

as soon as they get deselected, it stops

[faint pasture]

What would be a good parent class for a bultility for painting?

[odd ember]

I don't think there's many choices. I'd start with the editor widget base class

if you do happen to find a way to get the viewport from an editor widget do let me know

but I suspect I'll eventually have to write a subsystem for this

[trim marsh]

yo guys , i have this interface inside this function that is in tick event , but i need only call when i need it not every tick

[odd ember]

that I expose to the editor widgets

[odd ember]

then don't have it on tick

[trim marsh]

i need check the condition for example , so if true made something with the interface

[faint pasture]

What are you trying to do gameplay wise?

[modest gulch]

Question about blutilities, tutorial that I currently watch speaks about them, but looks like in current version of UE they are either gone or changed name. Anyone knows what can be done?

[odd ember]

don't watch those tutorials 😂

[trim marsh]

i have a condition running on tick that is an actor on screen(true) or off screen(false), so i need a interface to call when this occur , so for example , if actor is in screen , and i want to kill him , this only take action 1 time

[faint pasture]

Check if it's on screen and not pending kill

[odd ember]

sounds like you need an event dispatcher not running interfaces on tick

I don't know who first told people to abuse interfaces in BP

but they have a lot of blood on their hands

[trim marsh]

but inside the function?

[random plaza]

can 3d widgets in the world be affected by light?

im using a widget as a sign for workshops and they glow in the dark

[odd ember]

I don't think it's part of the functionality no

[random plaza]

i'll try and mess around with the material and see what happens

[odd ember]

a 3d widget is a wrapper for a widget, not an actual material

[gentle urchin]

Wouldnt a sign for a workshop be a mesh?

With a material?

[odd ember]

ordinarily

[random plaza]

i cant for the life of me figure out how to get a custom font on them though

so widgets have been a workaround

[odd ember]

you have to create that as part of the texture?

or use a decal or some such

[random plaza]

i'll look around and see what i can do

[odd ember]

there's also the 3d text render actor

[faint pasture]

@random plazaHave you tried a lit material yet?

[grand briar]

I realized why i need the map range by the way. Controlrot and actorrot are different ranges, if i add 180 to actorrot when it starts at -180 when controlrot is 360 actorrot is going to be 180 and vice versa

[gentle urchin]

They are, yet they represent the same do they not

[grand briar]

controlrot has a range of 0-360

actorrot is -180 180

so from 0-180 they are the same. then actorrot flips to -180 and controlrot continues to 360.. and actorrot goes to 0 in that time.. if i add 180 then it would be 180 at that time controlrot is at 360

[gentle urchin]

Right but this was just for comparison

So offsetting actorrot by 180 would give you a comparable rotator to the controlrot

As in, they are the same range

And if you wanted to remap the range, youd say in range is -180 to 180 and outrange is 0 to 360

[grand briar]

But the mapping i did worked. Took a while i'm not so good with maths. I don't want to confuse myself further with that really. I'm still trying to follow your instructions from before heh

[gentle urchin]

If it works it works !i may not have the full picture anyways 😄

[random plaza]

i fixed it, just switched to a text render with a offline font

[grand briar]

Sometimes i feel like i just hit buttons in the right order until things start working

[steady orbit]

I have a question about instanced static meshes. I want to make a star field, but I want to be able to click on each individual star and they all have individual data of any kind. Is this possible with instanced static meshes?

Kinda like an instanced blueprint actor in a way

[odd ember]

you'd need actors for that I'm pretty sure

or you separate the star meshes from the rest and write a script to populate triggers around instance meshes

[steady orbit]

I wonder how other games do it

Like stellaris for example

Having that many actors is so bad on performance

[odd ember]

are they made in unreal 🤔

[grand briar]

But stellaris doesn't have a star field with an enormous amount of stars if you dont count the background, which isn't relevant. It's just like any RTS where you could click on any building or any unit

[grand briar]

It's made in some paradox engine

[odd ember]

that would probably explain it

in house engines are often more specialized

UE is more general

[steady orbit]

Well yeah

That’s why I was here asking

[odd ember]

well you can only get answers based on the engine

although

I wouldn't worry about optimizing it before you've made it

[steady orbit]

I’d rather not delve into a project and ultimately know it’ll be a dead end

I’ve came at this before

I’ll keep trying

https://youtu.be/-3EB6KP10qw

I did find this for starters

[odd ember]

yeah but you can't be prescient about the problems you'll encounter

unless you have the experience to tackle them

[grand briar]

Wouldn't it be more important how much information you'd require from each actor rather than how many actors you have. I'm sure there are ways to limit that to what you need at the time. I don't think 100, or 1000 actors would be completely unreasonable for a game?

[odd ember]

it's not

and even so there are ways of handling that in post

[steady orbit]

I’ll try individual actors again.

[odd ember]

you can't fix something that isn't broken in the first place

[steady orbit]

Relax lol

[odd ember]

one of the reasons premature optimization is evil

[velvet swallow]

Stellaris stars are just a sprite, you can have several thousand of those clickable without performance issues in unreal.

[steady orbit]

Didn’t even think of that

[gentle urchin]

I do isms

With interaction

[steady orbit]

^^^^

More info?

I’ve looking into that very little

[twilit heath]

Linetrace hit object index corresponds with index of instance in ism component

[gentle urchin]

So each ism sort of points to a background actor woth the help of a manager

Exactly

So the actors have a ism and index ref

Which i iterate over for the the data lookup

[twilit heath]

For a SP game you generally dont need to worry while beliw 20-30k actors
