blueprint

[quick imp]

Thus why the first image was all over lol

I gotta rewrite

[smoky marsh]

Oh good heavens

[quick imp]

Yeah lol

I know

xD

[smoky marsh]

For the love of God just bind your functions to function calls

[quick imp]

xD

Coooouuuulllddd

Ill do some cleaning up here soon

[smoky marsh]

Set up a boolean for "can matchmake" with rep notify that enables and disables your button

[quick imp]

I dont think I have ever done that actaully

[gentle urchin]

rep noitify ?

is that needed?

[smoky marsh]

Well there is no don't rep and notify

[quick imp]

Replicate Notification?

[smoky marsh]

This would only be happening on client anyways, it's just a convenient way to run a function on a bool update

[quick imp]

Could you show me a simple example?

[gentle urchin]

Never used it like that x)

[smoky marsh]

That or event binding are the easiest options

[gentle urchin]

clever hack i guess

[quick imp]

yeah lol

[smoky marsh]

Not so much clever as lazy

[gentle urchin]

event binding is my preference

[quick imp]

Fair enough

[gentle urchin]

but sounds like alot for this thing

i'd just make a function for updating the bool and having the option to react to it

[smoky marsh]

Well the event would just bind to the widget event which internally then handles its visibility and such

[gentle urchin]

but oh well, dont mind me, you know about his stuff xD i should stop interfering 😛

[smoky marsh]

Nah, more opinions are always good

[quick imp]

The more the merrier lol

I need the honest opinions and the best ways to do something 😉

[smoky marsh]

The way I would essentially set it up is just having the button disable itself and then having it dispatch an event which starts the matchmaking

If it fails or is cancelled, send an event which re enables the button

[quick imp]

-_-

[gentle urchin]

That sounds like a good way to do it

10/10 would recommend

[eternal reef]

Id recommend to not stop the search after the first failed attempt but rather to continue searching and only stop it after (either a certain time has passed or x failed attempts * or obviously the user cancels the search)
Could be annoying to re-initialize the search again and again after a failed attempt for the user
But thats just nitpicking I guess

[smoky marsh]

Have it run an infinite loop with a cancel button

Worst thing is sitting in queue and it randomly stop searching

[gentle urchin]

isnt part of the problem with the default system that it mostly return servers close by, and will return them over and over?

meaning looping beyond the first result list is wasted ?

[eternal reef]

Not familiar with the system itself but filtering the full ones anyway would circumvent that issue?
My guess would have been if two players just connect at the same time for example (if only one slot is available) on the following search it would be filtered out anyway

[smoky marsh]

I guess you'd just get all valid ones, add unique to array, pick with lowest ping, on failure remove and chose next best

If all fail, rerun original loop since by now there should be a fresh list

And expand number of searches

[gentle urchin]

i dislike reroutes backwards but cba 😛

I suppose the list could be fresh yes, assuming enough players are playing (always a criteria)

I remember having issues finding a game across the pond when i tried the default subsystem

some regional filtering was going on (or based on ping?)

[smoky marsh]

I mean for a truly robust system you'd need to set up your own system for this and such, but at that point it's time for c++

[gentle urchin]

True that

Theres a free plugin tho

Which worked quite alot better

Advancedsessions plugin i think its called

A lot of extra options

https://forums.unrealengine.com/t/advanced-sessions-plugin/30020

[smoky marsh]

Yeah, no need to reinvent the wheel when this guy did it

[dense summit]

How to make a trigger

That prints "Hello"

[unreal quail]

is there any way to not do this?

(having to copy paste the string name)

[dense summit]

How to make trigger that prints "Hello" pls

[unreal quail]

did you try to right click and type "print" in search

ah you want the trigger logic too

[dense summit]

I did, I copied several tutorials exactly, but the trigger doesn't do anything

[unreal quail]

maybe your issue is that you copied several tutorials

[dense summit]

No I copied one, didn't work, deleted it, copied a different tutorial, didnt work either

[unreal quail]

show your OnBeginOverlap

[odd ember]

blackboardkeyselector

[unreal quail]

thanks 😳

[unreal quail]

then you have an issue with your collision

show the collision settings of your character and your triggerbox2

[unreal quail]

wait so how do I set the blackboard of the selector?

[dense summit]

the trigger is "Box Trigger" from "Basic", and the character is the default one that comes with sample project and it collides with floor correctly so why not trigger

[unreal quail]

that's strange, it actually should overlap

[quick imp]

Cant use it

I plan to upload this to marketplace for free, and well... I cant upload stuff I didnt make

Also I just threw this together and plan to test it here soon.

[unreal quail]

make sure this is like this for the triggerbox

[dense summit]

Yep that looks exactly like mine

[quick imp]

I have used advanced sessions, I have a few templates with it since I cant seem to get the one they supply working xD

[unreal quail]

did you modify the collision presets perhaps?

[dense summit]

Nope I didn't change anything at all

[unreal quail]

ah but that's only for BTTasks and other BT blueprints

I have an AI manager class that assigns stuff to the AIs

[unreal quail]

sorry I really don't know what's wrong with your project

consider doing a zip up and sharing it here if it's not too heavy maybe someone can take a peek

(only if you don't have starter content or a sample project's assets)

(it'll be too heavy if you have assets)

[odd ember]

as a variable. you can expose it so it shows up on your nodes in the BT. If you don't know this then I would suggest looking up some tutorials for BTs

[unreal quail]

no I understood what you were talking about when i looked it up, I'm working on an external blueprint that manages AIs (in fact I was on the AI controller in my screenshot)

the key selector only works inside the BT right?

[odd ember]

It works as a storage unit for the blackboard. you can break it for names but you can also set values directly on it. But a tutorial will tell you all this and more

[unreal quail]

I already watched multiple tutorials but I can't find anything on using blackboard key selectors outside of BTS/BTT/BTDs

[odd ember]

take a look at MathewW's video for blackboards maybe

[unreal quail]

😅

[dense pulsar]

Thanks for your help, it's working now

[unreal quail]

I don't think you're understanding my question, all of these usages only show how to do it from inside a BTS, BTT or BTD but I want to set a blackboard value from an outside blueprint (the AI controller or a manager BP)

I just watched his video out of curiosity and it doesn't have my answer either

[odd ember]

A blackboardkeyselector is the type of variable that the blackboard uses, independently of any BT.

[gentle urchin]

Oh 😅 i had good success with it ! After a few head scratches and whatnot

[odd ember]

you said you wanted to have a different way of doing names of values for BBs. Blackboardkeyselectors are just that

[unreal quail]

yeah but they don't work if it's not a parameter of a BTT, BTS or BTD no?

[odd ember]

It has nothing to do with BTs

read what I am writing

[unreal quail]

I read it but it still doesn't tell me how to functionally use it on an AI controller BP it just doesn't work

[odd ember]

BTs can easily expose these. But the BB data structure exists on its own. If you want value transfer, blackboardkeyselectors are... key

[odd ember]

it's a struct

it has built in BP functionality

again if you took a look at a tutorial for blackboards they would tell you this

[unreal quail]

it doesn't 😅 😅 😅

it only shows for BTS, BTD and BTT

not how to set it from the controller

[odd ember]

are you watching them all the way through or just skimming? they are set the same way no matter where you have them

doesn't matter if it's inside a task or in the controller

[unreal quail]

none of the tutorials use BKSes outside of BTs

unless I missed something

[odd ember]

doesn't matter

[unreal quail]

I watched several hours of (sleep inducing) official tutorials on BTs and AI

[odd ember]

the way you set up a BB is the same

whether you use it inside a BT or not

[unreal quail]

here they are literally doing what I said I didn't want to do

[odd ember]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Utilities/Struct/MakeBlackboardKeySelector/

[unreal quail]

but that would make me have to write the FName as a string literal all the same

so what's the point?

my whole question was if I can use the fact that I know which blackboard it's running to use select the FName (or key) instead of writing it down as a string literal

[odd ember]

the FName is the variable name in the BB. you can either use FName or you can use a blackboardkeyselector. Those are your options

[quick imp]

Fair enough

[unreal quail]

but I would still have to make a blackboardkeyselector struct by writing down manually the FName of the variable

so in all cases I'll need to have a string literal somewhere

which is what I want to avoid

[odd ember]

or you could store a BB key on its own and move it from one BB to another

Ive never had to use FName for any of my BBs

[unreal quail]

store it where?

[odd ember]

as a variable

on whatever class you're using

ai controller or what have you

[unreal quail]

you mean store it as a BKS?

[quick imp]

Has anyone else worked with User Game Settings? I havent been able to get my working...

[odd ember]

yes

those are your options

[unreal quail]

you mean getting it from the BT to the AI Controller through a service and storing it there right?

[odd ember]

how you get it is up to you

[unreal quail]

because you can't select the value on the class defaults (since it doesn't know which BB it is)

[odd ember]

it's a struct

[spice smelt]

Hi, is there any guarantee about the order in which construction scripts are called? In particular between an actor and its components

[smoky marsh]

Why are you doing this now again?

[unreal quail]

I just don't want to copy paste the FNames from my blackboard but I guess I should simply do that

and avoid myself all this pain

[smoky marsh]

Why don't you just make a map

[unreal quail]

instead of using a blackboard?

[smoky marsh]

No as in from key to fname

[unreal quail]

the key already contains the fname

[odd ember]

you'll never be able to set up stuff like that for class defaults. what are you even trying to do? it sounds like you're trying to hack BBs to work in a way the aren't supposed to

[unreal quail]

@odd ember I just want to have a manager BP that assigns some values in the blackboard (task location and such)

of managed AIs

[smoky marsh]

It sounds like you're after a similar functionality to easy utility ai

[odd ember]

but like... why handle this outside the BT?

[unreal quail]

because it sucks at handling multiple task locations that can be fulfilled by multiple AIs (and that need to switch from time to time)

[odd ember]

if you're trying to make an AI director type thing you are better off considering subsystems

[smoky marsh]

Paid plugin, don't own it, but friend who has it describes it as what you're after

[unreal quail]

it's not supposed to be anything mind blowing but I'm already hitting walls

[unreal quail]

no thanks, I don't really like using plugins

[odd ember]

and to be honest you can wrap stuff like this in a BT

[unreal quail]

I already have a BT for individual AIs

that's why I'm using a blackboard

[odd ember]

anyway this is more #gameplay-ai at this point

[unreal quail]

I guess the answer for my question is that I should just copy paste the string literal of the FName 🤔

[odd ember]

yeah but it sounds like you're trying to hack the architecture. which is probably why you're in the situation you're in

[unreal quail]

not really I mean it's pretty common

as I showed on that screenshot, for instance when hooking the perception system they make string literals

[odd ember]

never seen anyone do it like this before

[unreal quail]

???

or you mean the manager?

the manager is not really the issue here

[odd ember]

I personally query the director from inside the BT, and the director sets up appropriate roles

[unreal quail]

I thought about it but I don't really like that approach

[odd ember]

setting BB values directly seems like a strange way to do it

well then you're kinda painting yourself into a corner, no?

[unreal quail]

I mean I don't see any issue in setting BB values from outside as it's always done in one way or another (example being the perception system)

and that's not even really the question here

but I guess if Epic Games copy pasted the string literal it means I should as well

[odd ember]

I think most people would use a service... That's kinda why they are there

[odd ember]

your question has been answered

[unreal quail]

but why use a service that is going to keep asking if there is a new task available when I could just tell the AI directly when it is

but well, thanks anyway @odd ember and the others that hopped in

[odd ember]

I don't use a service to query tasks, I use a service to move BB values. you're conflating the two

[unreal quail]

yeah but the service will just keep checking for no reason if the BB value doesn't need any changing

[smoky marsh]

Once again, plugins are made by people who have these issues and find another way to fix them

[odd ember]

you would be better off having a discussion about setting up your ai architecture in #gameplay-ai. It sounds like you're trying to do things that are going to be difficult for you

[smoky marsh]

You could also code your own plugin

[stiff raptor]

I was doing other stuff so sorry for late reply. You might know a better way to do it. In the first picture, you can see I am making different units when the buttons are clicked and there's a macro called "breedable check" which checks if the player can make the units. If not, the game follows the specific exec pins. In the second picture, I am displaying with a text box the reason why the player can't make the units. Also I can't do the entire thing with functions is bcoz I have to check differently with different types of unit. See the breedable check macro takes a pin called "Ant Type" which determines the type of unit I'm trying to make. So is there a better way to arrange it?

[odd ember]

@unreal quail

[unreal quail]

I asked a question in there and got no answer already (and really I'm fine with the way my system works currently, in fact I remember someone advising me specifically to use a manger bp)

[odd ember]

a manager isn't bad, AI directors work. but it doesn't sound like you're using it the way you would ordinarily use one. which is why I recommended #gameplay-ai

but it's up to you. If you prefer painting yourself into a corner I'm not going to stop you

[unreal quail]

I didn't really think about how I should use the manager, but you might be right a service could be better

[odd ember]

we can continue in #gameplay-ai if you want

[unreal quail]

sure!

speaking of manager, does anyone know of a good way to have an array of locations in editor that can be moved from the level editor?

[earnest tangle]

Use empty actors

[unreal quail]

custom actors or regular actors that need to be attached to the "manager"

only the manager BP needs to know the locations

[odd ember]

see #gameplay-ai

[candid nest]

Hey can anybody help me i want to spawn actor bheind my player character when game begin i dont know how to do it pkz help

[smoky marsh]

Look up how to unreal 101

Well all jokes aside, on player spawn send request to world to spawn actor

Well, on begin play

[candid nest]

Hey i want to ask something i am making my level inside the blueprint actir as it will spawn when my game mode will run so can i add navmesh there the level is infinite never ending how can i do that

[dawn gazelle]

I would create a button widget that contains your desired appearance using exposed variables, including for your Ant Type. You can create an event dispatcher that you call when then button is clicked that returns the ant type.
On Constructions of the widget that would hold these buttons, you loop through an array of your ant types, creating and adding the new button widget to whatever parent needs them and also bind to their event dispatchers.
The bound event will return the ant type, allowing you to feed it into your macro, which you can then hook up into the 3 different output options you have.
As you're now using an array, it's also much easier to expand -- all you have to do is add another ant type to your array and it'll automatically have the button and logic created for it.

[winged sentinel]

is there a way i can constraint a vector to be within the bounds of another? I essentially want the spawn location to always be inside the boundaries, and if not move to the nearest location that is inside

[earnest mango]

@winged sentinel If your spawn bounds are a box, you could use RandomPointInBoundingBox. Otherwise, you could use some combination of other random functions, like RandomUnitVector for direction and RandomFloatInRange for distance

[winged sentinel]

i see, i beleive random point in navidable radius works, seems like its always spawning with in the nav mesh. thank you!

[rose citrus]

is there an easy method to scale something in only one direction? I'm trying to create a dynamic hitbox that spawns and I can plug in how long it is based on the X, but I want it to scale only from the right or left side...if that makes sense.

[trim matrix]

it might be a stupid question, but i like asking stupid questions so...

what is the threshold of a "While" loop in UE? (or any other loops)

[thorn fiber]

https://forums.unrealengine.com/t/blueprint-loop-iteration-limit/137934

[thorn fiber]

Make a vector plugging in a float var that you change?

[rose citrus]

the problem is when I scale it, it scales on the x-axis on the left and right side, so the hit box goes through the player. I want it to only scale away from the player

[trim matrix]

thank you thank you. i didn't know what to google for, i tried searching for while loop threshold but it didn't work so thank you!

[trim matrix]

I think you'll have to offset its location the same value you scale it

[thorn fiber]

Scale is in meters so you will have to multiply by 100

so + 1 cm is + 0.01 scaling

[rose citrus]

that's what I'm thinking of. Just trying to find out how to add scale to location

[gentle urchin]

Offset by its halfsize in the direction you want it to move out from

HalfSize is its size*scale/2

[rose citrus]

like this?

I tried this but it still moves around when I scale it

[umbral ginkgo]

How can I get a callback to a previously spawned actor? Right now I'll spawn said actor, but then destroy all actors of class which can obviously be problematic.

wait

I have an idea

[gentle urchin]

You're using its location to set its new location

You should use the owner to do it i think

[iron bone]

Hey everyone, I'm trying the much used Playstation over the shoulder type of 3rd person camera and I'm happy with the way it looks but it's messing with a few of the mechanics I've set up that rely on the camera being in the center of the screen. I have this dash that is now launching the character in a diagonal where as before it was launching the character directly straight ahead. Wondering if an offset would fix the problem and also wondering where it would go in the launch velocity. Thanks!

[odd ember]

well IMO it's a design question: should camera direction matter for which way your character should dash?

[iron bone]

I think it's a bit confusing for the player when it's not directly ahead, especially when dashing a long distance then trajectory changes a lot

not directly ahead of the player mesh*

[odd ember]

what if the player character is facing to the side?

[iron bone]

the player gets rotated towards the direction of camera

that may complicate things?

they get rotated before launching

[odd ember]

if the player gets rotated to the direction of the camera, why not use the direction of the character?

[iron bone]

true!

I was making it more complicated than it needs to be

[crimson mulch]

Hi im trying to make a blueprint where if i click E actors will follow the player and then all stop following if E if pressed again. Anyone know why this aint working?

[flat coral]

I feel like that line from the ForEach to the FlipFlop cannot possibly be doing what you want

[odd ember]

you can't mix two execution paths like that

[flat coral]

Also yeah. Just store the list as a variable on BeginPlay, and then get it when you press E

Also that Sword Fighter Ref, I have no idea what it points to but it's definitely not going to iterate through all your sword fighters in that list

[crimson mulch]

hmm okay i'll try change this up a bit then

[umbral ginkgo]

Im getting a "pending kill" error on a node that destroys an actor. The actor gets destroyed multiple times but the function cannot be called unless the actor has been spawned in again. Why is this?

[flat coral]

Wait what do you mean it gets destroyed multiple times? I'm pretty sure an actor can only be destroyed once

[umbral ginkgo]

I can see your confusion

[flat coral]

In fact that's why. "Destroy Actor" is a function that requires the actor to be alive. If it's already destroyed, then it isn't alive to BE destroyed

[odd ember]

UE's way to avoid beating a dead horse

[umbral ginkgo]

The "actor" is actually just a variable for an actor that is spawned in

[flat coral]

So it's a pointer that can point to different instances of the actor

[umbral ginkgo]

Yes essentially

[odd ember]

just preface your destroy function call with an IsValid

and you should be fine

[flat coral]

Pretty much this ^

[umbral ginkgo]

Thing is I'm already doing that

[flat coral]

This is the part where we ask to see the code, I think 🙂

[odd ember]

you need to show your where you get the error then

[umbral ginkgo]

Sure

[crisp lance]

From an actor component's event graph perspective, is the owner guaranteed to always be valid (not null)?

[odd ember]

it sounds like you're trying to operate on an actor that is already dying

[odd ember]

not null, sure. but might be pending kill. in which case you'd still get an error

[crisp lance]

Fair enough. Thanks!

[flat coral]

I don't see the isValid call?

[odd ember]

well you're not checking is valid

[umbral ginkgo]

isDelivered ai

[odd ember]

not the same

[flat coral]

^

[umbral ginkgo]

How?

[flat coral]

I have no idea what that even is, that's just a boolean you're setting

[odd ember]

is valid is a low level check that determines whether your actor is still alive

it has nothing to do with your custom bool check

[flat coral]

I guarantee that if you convert the Spawned Actor Get to a Validated Get, the problem will vanish

[umbral ginkgo]

OH

im stupid

[odd ember]

ah yeah, validated gets are great

[rose citrus]

@gentle urchinThank you! I multiplied the size of the hitbox by the scale and halved it and now it works properly

[gentle urchin]

Sweeet !

[umbral ginkgo]

I never even knew such a thing existed; thank you

[flat coral]

Oh man it's a lifesaver

Go from "Problems" to "No Problems" in one right-click

[runic parrot]

Hi! i'm having a little problem when i update a widget within my HUD.

If i change the design of this widget, then i have to go into HUD to update the reference to it gets the new version of the widget (right mouse click - Replace with ***)
sometimes that breaks all the reference, any way to bypass this?

[smoky marsh]

A soft reference? What exactly is it you're replacing each time?

[runic parrot]

it's a variable within the HUD that it's another widget

[smoky marsh]

Weird

Just compiling both should be enough

[crimson hornet]

Hello, so I got an question. So right now I have this piece of code where the actor rotates towards the player only problem is he teleports does someone has an idea to make him rotate smoothly.

[smoky marsh]

Lerp

[runic parrot]

most of the time that's the case, but something i get this "_C" added next to the class i try to replace, in order to update the reference, and it breaks everything : (

[smoky marsh]

I'm unsure then, maybe another wizard knows what's up

[crimson hornet]

tried a lot of thing but it just didnt work also tried lerp

[smoky marsh]

If lerp didn't work then I'm unsure

You could make a bezier curve i guess

[crimson hornet]

could you maybe go a little more indepth with lerp?

I tried somethings on internet with lerp

but didnt help

[runic parrot]

lerp on tick or every "X" secs, or maybe a timeline.

[willow phoenix]

@crimson hornet did you connect the the node with anything? 😄

[crimson hornet]

yes

[willow phoenix]

can you show where you connected it?

[crimson hornet]

just for easy example

sure

[smoky marsh]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/Float/Lerp/

Just chuck a timeline on that alpha

[crimson hornet]

@willow phoenix

but he rotates tho so it works

[crimson hornet]

okay ill try

[smoky marsh]

Is that cast to a cpp class?

[crimson hornet]

im casting to the actor

the enemy

[smoky marsh]

Just cast to generic actor

Or skip casting completely

You don't want to cast to bp

[crimson hornet]

im casting to bp actor

[willow phoenix]

uhm, why don't you just have this on the actual actor that you want to rotate?

how often do you call the event?

[smoky marsh]

You don't want to though.

Cast to blueprints that is

[brazen merlin]

dont need to cast either

[crimson hornet]

?

[brazen merlin]

this current setup fires once, or whenever this notify fires. Rotating to look at something happens over time

[willow phoenix]

im more interested what the "IceBoss" is supposed to do. player comes near, ice boss rotates?

and again, why did you not implement the code that clearly is meant for your ice boss ON the iceboss?

[crimson hornet]

he does an attack an mid attack he rotates towards player

[brazen merlin]

tick, timer, or timeline are the options for this - based on whats comfortable for you

if you go with a tick, you'll be using a gate and events to open and close it

[willow phoenix]

or if its poormansanimation use a timeline 😄

[smoky marsh]

If it's an AI then look at target works

No need to translate like this

[brazen merlin]

seeing as it's one value, a lerp could work, otherwise an interp

[willow phoenix]

lerp for timeline, rinterp with the tick (and the delta seconds)

[crimson hornet]

I cant use timeline or tick in anim bp

[brazen merlin]

true, but you do have anim notify 😛

[smoky marsh]

Is this singleplayer?

[crimson hornet]

yes

[smoky marsh]

Just root motion it then, easy fix

[crimson hornet]

but he doesnt rotate then

[smoky marsh]

Are you using blackboards and such?

[crimson hornet]

yes

[smoky marsh]

Cus there is a look at function

So on queue look at player and then launch attack

[crimson hornet]

this one right?

[smoky marsh]

Oh no not literally look at function

I think it's look at actor or something like thay

That*

[crimson hornet]

Find look at rotation?

[smoky marsh]

Or rotate to actor

[brazen merlin]

Manne is referring to the LookAt Task in BT

[smoky marsh]

Thank you

[crimson hornet]

oh

[smoky marsh]

I'm not by my pc and it's been a while

[crimson hornet]

but how call it from an anim notify?

[brazen merlin]

I think its called RotateToBBEntry

[brazen merlin]

because you are using notify events, i would think to have one event which allows it and another which stops it and those BT Tasks are setup to watch that BB key

fwiw, i handle this look at concept within my controller bp

and I use my own Tasks to call the look at events to start/stop

[smoky marsh]

I'd just deal with this using gas tbh but since its singleplayer no need to dive into the deep end

[crimson hornet]

im lost tbh

[smoky marsh]

Uhh, just like stick to how you were thinking of implementing it with transform

You learn as you go

[faint pasture]

@crimson hornet Start over, what are you trying to do?

[brazen merlin]

a look at player over time function

[smoky marsh]

No need to force advanced concepts on you if this is new

[brazen merlin]

still think it would be better to do it not in the anim bp

[faint pasture]

Yes, nothing regarding time should be happening in the anim bp.

The anim BP should just have as data a Look Direction. The actor should modify that over time.

[crimson hornet]

so should I call an function in the animbp and that function is getting handled in the bp?

[faint pasture]

Anim BP reads pawn data

Not the other way around

So if pawn has a variable LookDirection, anim BP can use it.

Now you could maybe do some time related stuff in the animBP like

AnimLookDirection = RInterpTo(PawnLookDirection)

Or whatever

Depends on how "over time" you want this to be

[crimson hornet]

this is c++ right?

[faint pasture]

And if you want the ACTUAL look direction to be used for gameplay purposes like firing weapons etc.

[faint pasture]

No it's b******* pseudocode to make a point.

But since you're asking, don't do that. Animate LookDirection over time in the pawn

[edgy glen]

Hello, I'm using Atan2 to get the angle of my attack angle in degrees, but I only want it to print the string if the joystick is pushed > 0.25f, but I can't figure out how to do it while using Atan2, would anyone have any ideas?

[odd ember]

branch on axis value > abs(.25f)

[trim matrix]

Add a > condition to your axis value and add a branch to it

Or even your return value just before the print

[edgy glen]

I did try that first, but for some reason it wasn't working correctly, I tried a few things after that and didn't find another way, I must have not connected something earlier because now it's working, thank you for your quick replies

[novel rock]

how do i get in line?

[odd ember]

in line for what?

[novel rock]

to ask for help

[tight schooner]

Just ask

[novel rock]

i did

how do i attach and detach one object to another with blueprints.

[trim matrix]

Attach component to component or attach component to actor

And remove from parent to detach

[tight schooner]

So what happens if you just Get Player Pawn and Attach Actor to Actor with the vehicle as the parent?

(without all the Cast To and Get All Actors in between)

[novel rock]

it crashed

[dawn gazelle]

If you're doing this in the level blueprint, you may as well use the Sedan reference you have already instead of doing a "Get all Actors of Class" call for it.
You're calling "Player Parent" function from within the "Player Parent" function - causing an infinite loop.

[glacial granite]

I'm feeling stupid but I cannot get arrays to work, is this debug lying to me?

[novel rock]

yes i'm doin this in the level blueprint.

[dawn gazelle]

Yes, sometimes the output debug won't show the right value. If you print that value on to the screen, then it should show you the correct value stored in the array.

[glacial granite]

ahh alright, thank you

[desert juniper]

Debug should show the right value no? I haven't run across this issue before at least 🤷‍♂️

@glacial granite have you checked you have the right debug filter selected?

[glacial granite]

I do

ah the print did the trick, thanks!

[desert juniper]

Maybe it has to do with the Editor Symbols not being installed

I know in cpp at least you get wonky values on debug if you don't have them installed

[umbral ginkgo]

How can I disable collision on an object (Trigger) for only one actor?

[desert juniper]

If you're going to be doing this a lot, you can create a new collision mask

[brazen merlin]

always?

[umbral ginkgo]

No just temporarily

[brazen merlin]

when do you want it off?

[desert juniper]

maybe just check against that particular actor, and don't proceed with logic if it matches then?

[umbral ginkgo]

As it is now, when the player does one thing it gets turned off but when they do another it should be turned back on again

[umbral ginkgo]

That could work but I was wondering if theres a better method to doing it

[desert juniper]

I don't believe you can turn it off on a per actor basis

[novel rock]

I needed to drag it in from the World outliner

[desert juniper]

there's plenty of ways to check if it is that actor however.

[brazen merlin]

still not very clear 😛

[desert juniper]

you can do interface calls, tags, casting, type checks, etc

[umbral ginkgo]

Yeah, it probably can work

Thanks for the help

[desert juniper]

If you want to turn the whole thing off, you can just set the component to disabled as well

[faint pasture]

Kind of a design question here, but for a Lego-style vehicle building mechanic, does an odd or even unit size feel better?

like an engine, would you prefer it be 3x3x3 units or 2x2x2 bigger units? should the centerline of a vehicle be at a coordinate or between them?

[brazen merlin]

even? lol

[faint pasture]

The only problem I see with even is that a 1 wide part can't be centered

[desert juniper]

Odd so that you can have a middle

[faint pasture]

Ye

[brazen merlin]

i thought the same for odd too, that there is a middle, but the same would be for even, just not a pip but between

odd does sound nicer for granularity

[faint pasture]

maybe if things come in multiples of 20cm but can be place in multiples of 10cm

i think that'll settle both

[desert juniper]

for a middle with even you'd have to do 6x6 and turn middle two into the middle piece

which might be too wide sometimes? 🤷‍♂️

[faint pasture]

The lego analogy would be that my smallest piece is 2x2 and everything is in multiples of 2

so no 3x3 piece

[brazen merlin]

i think its a matter of detail/granularity that you want

[umbral ginkgo]

How deep does the mechanic go? Is it similar to a game like stormworks where you build everything yourself or is it more simple?

[brazen merlin]

seems like the same sort of thing to handle, 1x1 would just mean smaller bits, but you'd still be managing chunks of blocks no less

[faint pasture]

It's the core mechanic, building a vehicle out of parts. The vehicle basically has a grid so parts snap to 10cm grid.

I just want the grid to be fine enough to not feel cramped but course enough to do by mouse really quickly

I'm leaning towards 10cm grid and part sizes multiples of 20cm

[umbral ginkgo]

In that case I think 10 cm would work better

[faint pasture]

part size being the size of their bounding/collision box

certain things snap together like driveshafts and pipes etc so it needs to be on a neat grid

[brazen merlin]

the banjo kazooie game had it rather small, lego games as well - and people will go as crazy as they like in minecraft

[umbral ginkgo]

I suggest you look at a game called stormworks in terms of grid design. It has very similar mechanics to what you described

[astral epoch]

Is it possible for a child class to inherit its parent's macros?

Can't use functions for this purpose as they contain latent nodes that won't work in them.

[brazen merlin]

do they not pop up when you search for the macro in the child? or as an override option?

[faint pasture]

2:10 for the part movement mechanic
https://youtu.be/WAZWfSwHFXk

[astral epoch]

Nope.

[desert juniper]

odd 100% to allow for symmetry when placing items that don't need to symmetrically go on both sides

also, damn that looks cool

[novel rock]

I cant get the sedan > sitPoint to attach

[desert juniper]

sit point is probably a component, and you're trying to attach actor to actor

[novel rock]

Oh

[umbral ginkgo]

How do some of y'all sculpt your connections between blueprints?

[novel rock]

Functions?

[crystal mural]

Having a lot of trouble figuring out what's going on here. It's supposed to be adding 5, but it's adding 11. This is in the parent class of my enemy characters.

[umbral ginkgo]

Nah I mean like the visual connections between blueprints

[umbral ginkgo]

kinda like this

[faint pasture]

I stack up inputs to execute node as much as possible, and dont run wires everywhere

[novel rock]

Like This?

[umbral ginkgo]

Oh are those macros?

[faint pasture]

Like this

Heres a much bigger example. This is a tire model.

[umbral ginkgo]

thats probably the most effective way of doing it

[feral ice]

can I access timeline point? I want to dot to start on any position depending on the players location.

like this

[gentle urchin]

Sounds like an alpha instead?

Whats the usecase

[feral ice]

the purpose is to zipline. I vinterp between two location and depending on where the player is i start on that location and interp the rest of the way

if you understand?

[odd ember]

IMO it's always better to use floats as an alpha and lerp

then you can also do multiple things with a single alpha value

[feral ice]

what is alpha

[odd ember]

a 0..1 float

[feral ice]

0 to 1 float

?

[odd ember]

yes

you use it to lerp between stuff

[umbral ginkgo]

is there a node for checking which actor (In this case being multiple triggers) was overlapped?

[odd ember]

it's an exposed pin on the OnComponentBeginOverlap

[feral ice]

how do i get the alpha node what do i search for?

[odd ember]

it's just a timeline curve with a float, instead of vector

set between 0 and 1

[umbral ginkgo]

I tried overlapped component and other component and neither worked

[gentle urchin]

For a variable length zipline interpto might be easier?

[odd ember]

overlapped component is the component that got overlapped locally

[feral ice]

yo guys thanks for the help but im still lost what is an alpha thingy

is it a node

is it inside of timeline

[odd ember]

you can interpto with a lerp later on, but tbh a lerp will likely be fine on its own

[odd ember]

inside your timeline. create a float track

[feral ice]

yes

[gentle urchin]

Alpha is used to control a lerp, from 0 to 100% between A and B

0 being A

[odd ember]

then just add point as you want. keep it between 0 and 1

[gentle urchin]

0.5 being midpoint a to B

1.0 being b

[odd ember]

over however long duration you want

[feral ice]

thats what i aldready did, wasn't it?

[odd ember]

you said you had a vector right?

just replace it with a float

[gentle urchin]

True with playrate

[odd ember]

that's it

[feral ice]

this is the code atm

not finished ofc haha

[gentle urchin]

The timeline goes from 0 to 1 over 1 sec

[odd ember]

your lerp value goes into a lerp node!

[tropic pecan]

Hey there, not mean to get into anybody's conversation. If anybody has a moment with me, I'd like to ask for some help on sorting out with Enumations and structures cause I'm trying to create a attack impact behavior though I'm a little confused how to make such a possibilities along with enumerations and structures together

[odd ember]

I think a little more detail is necessary

what do you have to account for? is it a finite amount of data?

[feral ice]

this is the timeline, is everything correct this far?

[tropic pecan]

Well, it will be a little complicated to say but I'll try to explain the best I can do and I may need to give much of my structures in image.

[gentle urchin]

0 to 1 over 1 sec

[odd ember]

yes, but keep in mind: usually alphas run from 0..1, and yours runs in reverse. just means you have to invert your vectors in your lerp

[feral ice]

oh ok

[gentle urchin]

Playrate = 1 / (zipspeed / zipdistance)

[feral ice]

is playrate delta time

[gentle urchin]

No

[odd ember]

playrate is the scale of your timeline duration

[desert juniper]

Seems I can't modify a rep notify variable in an interface
is the best bet just to create an event to do so intead?

[gentle urchin]

To avoid superspeed on long ziplines you slow down the timeline

[odd ember]

have you asked in #multiplayer ?

[desert juniper]

🤦‍♂️ my b

[desert juniper]

may want to start with what you're trying to accomplish instead of your code

[feral ice]

zip speed is that lerp or what is that

[odd ember]

zip speed is what was posted earlier. it's a function of the playrate

[tropic pecan]

Ok, I've tried to gather what information I could get because my little question involves a lot of detail. I've settled up elements and weaknesses using Enumerations and Structures to sort out. I have damage structure in my actor unit and I'm trying to sort out a way to make what kind of reactions occur on what element attack is used. I've already figured maybe the switch would work but how to connect the reactions with structure and enums from the attack and unit to the element.

[gentle urchin]

Desired speed while ziplining

Should be a variable of yours

To define how fast the actor ziplines

[feral ice]

is this what you mean

[gentle urchin]

No

Just make a variable

[feral ice]

i mean for @odd ember

[gentle urchin]

Type float

And start with 200.0

Will give you a reference speed

[odd ember]

I meant this @feral ice

[feral ice]

this means that wherever you are you will still have the same speed

[gentle urchin]

Yes

As a start

[icy dragon]

I think this is where GAS could come into play 🤔

[tropic pecan]

GAS?

[gentle urchin]

You could adjust it by decline on the zipline @feral ice

[odd ember]

ok so if you're doing resistances, you'll probably need a map between your type (enum) and the value (float)

[icy dragon]

Gameplay Ability System

It does involve some C++ tho

[odd ember]

gas requires CPP to function though, no?

[feral ice]

ok

[odd ember]

yeah so it's not really viable for this channel

[tropic pecan]

I don't use C++ I'm sorry to say.

[desert juniper]

you can get mostly by without CPP if you use something like GASCompanion

[gentle urchin]

So start with the timeline, lerp vectors and set location

[desert juniper]

planning for this to by multiplayer?

[odd ember]

well tbh instead of acting like gas salespeople let's try and solve this issue

[tropic pecan]

So, I might need a map between my type enum and value float. I'm not sure how to do that. Can you explain or even show me a structure of it?

[feral ice]

yes

[odd ember]

a map is a type of collection, like an array

[tropic pecan]

No, I'm remaking a game I really loved cause I refused to move on from it yet.

[desert juniper]

then yeah, gas may be overkill 🤷‍♂️ if you're not experienced in cpp. go listen to CE

[odd ember]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Maps/MapNodes/Add/

surprisingly (or not) the UE4 documentation is sparse on this

[tropic pecan]

I'll look into this, thanks!

[odd ember]

now I'm wondering if there is such a thing as an individual map pairing as a variable 🤔

[feral ice]

So im changing the delta time and not interp speed? Need to know what im supposed to know before getting into the good stuff

[gentle urchin]

You're changing the alpha on a lerp node

[odd ember]

use a lerp!

[gentle urchin]

Which is how far from A towards B we are

[feral ice]

where in this picture can you find a word alpha im lost

[gentle urchin]

Swsp the node

[odd ember]

the value you call lerp is an alpha value

[gentle urchin]

Ditch vinterp to

And use lerp instead

[feral ice]

okay i will chnage the name to alpha

[odd ember]

lerp is a node

[feral ice]

this one

[odd ember]

yes but for vectors

[feral ice]

oh yeah i see didn't that one existed

[odd ember]

just for full transparency, lerp is a short for linear interpolation

[feral ice]

ok sorry for the trouble

[gentle urchin]

Misleading name isnt it

Since it supports extrapolation aswell

Anyhow 😄

[odd ember]

linear polation

[feral ice]

yes ik this but like vinterp to i tought that meant vector linear interpolation to

[odd ember]

interp works differently

[feral ice]

idk myabe im stupid haha

[gentle urchin]

Very differently

Even more different is the vinterp to const

[odd ember]

interp takes e.g. a distance, cuts it into Interp Speed segments, and then moves towards the end of the first segment

[gentle urchin]

One of them handles delta time, the other does not 🧐

[feral ice]

hmm i see much to discvoer after all

[gentle urchin]

Just do the lerp

Plug in the alpha and the two vectors

And you're done

[odd ember]

I want to believe this is an obscure reference, but I'll leave it

[feral ice]

yeah the next step is pretty "simple". i need to now the distance from where the actor is to the end loc and then skip interp until the actors position

that way i dont start from the begining

[gentle urchin]

Wha

To the start loc you mean?

[feral ice]

yeah thats true

[gentle urchin]

Start loc would typically (tomb raider style) be some jump distance away from the lines nearest point to the jumping platform

But thats way down the line

[feral ice]

well yes i can see how they did that

[gentle urchin]

Start with just getting it to slide ever so ugly from point a to point b

[feral ice]

idk im getting tired haha just gonna do tha ugly shit first. haha. 23:33

[gentle urchin]

Yeee waiting for kiddo to sleep so i can hit the bed lol

[feral ice]

hahaha

[gentle urchin]

Zipdistance is just the two vectors in with a 'distance' node between em

So playrate should be set to
1/(zipspeed(your float variable)/distance)

[rich granite]

Hey all! Thanks for all the help so far, but quick question: how can this cause an infinite loop?

[gentle urchin]

The widget

Does it have some stupid logic on event construct ?

[rich granite]

Uuuuuh, please hold.

[gentle urchin]

Not sure how stupid it'd have to be to actually cause a infinite loop

😅

[odd ember]

could be recursive

[rich granite]

Negative, the widget just has a variable that the character updates via casting.

[gentle urchin]

Yeah thats the stupid part

No judgement ofcourse.

[odd ember]

I mean infinite loops in BP aren't really infinite

[gentle urchin]

For sure they are not

[odd ember]

it's just the editor deciding when to stop

[gentle urchin]

Usually way lower than the actual loop count

Default is what, 1 mill ?

[odd ember]

lower

like 10k

maybe 100k

something like that

you can change it in the project settings afaik

[gentle urchin]

Update health, pure functions..

Yes you can^

I usually just tenfold it when i need to

[odd ember]

I've never had to

but yeah it's just a number

anyway yeah those pure functions are suspect

[gentle urchin]

Along with death

What does that do

Respawn?

Theres the loop then

Beginplay -> is dead -> destroy actor -> spawn actor -> beginplay ->>>>>>>>>

[rich granite]

Death just destroys the actor.

No respawn set up yet.

[odd ember]

I don't know if it's something to do with the issue

but those pure functions can't be pure

[gentle urchin]

But are they ever executed like this? I dont know,

But i wouldnt trust it

[odd ember]

they wouldn't be

[rich granite]

Okay, so it's definitely something to do with the damage:

I added in the damage cooldown to test it

[odd ember]

probably those pure functions will be at the core of it

[rich granite]

Can you unpack that for me?

[odd ember]

functions that set variables cannot be pure

pure functions are usually reserved for function that get variables, or calculate a result without modifying state

[rich granite]

So something like this would be better?

[odd ember]

I would kill the update health functions

those are the ones that shouldn't be there

but otherwise, yes

[feral ice]

Im not sure i follow this formula. Im not sure what to do with ziplinespeed.

[gentle urchin]

What in gods name...

[rich granite]

Okay done. Still looping tho.

[gentle urchin]

Alpha goes directly into alpha

[odd ember]

are you familiar with breakpoints?

[gentle urchin]

Show the death function please

[rich granite]

I am, but I've forgotten how to set them.

[odd ember]

F8

[feral ice]

thats why im confused cuz im skipping the first interpolation like im taking away the part that i dont need to zipline

[gentle urchin]

Alpha into alpha

Thats all for the loc

[dusk edge]

Sorry if i'm interrupting. but does anyone know if there was ever a fix to this?
https://answers.unrealengine.com/questions/1049560/view.html
I'm having the same issues that these guys are discussing.

[feral ice]

no bc if im in the middle of the zipline i will teleport to the start and start gldiing

[gentle urchin]

Lets handle that afterwards

Thats the event call that needs to be fixed

The interpolation here should have a pretty simple job

[feral ice]

ok now its like this

[gentle urchin]

Sweet

Before play from start

Get the timeline reference from your variable list

Set playrate

[gentle urchin]

Perfect

Now the math for the playrate

[feral ice]

should probobly rename it haha

[gentle urchin]

No worries about that now :p

[feral ice]

what does playrate mean? how fast it will go from 0 to 1?

[gentle urchin]

Yeah

Playrate = 1 means 1 second of timeline lasts for 1 actual second

Playrate of 2 would mean twice as fast, or half the time if youd like

The reason for the math is to compensate for the distance , and keep a steady speed regardless of length

[feral ice]

yeah cuz when i thought about making a zipline i knew the speed would differ and thats what i didn't know how to change or how the timeline really worked

but its like this now

[gentle urchin]

Perfect

Now test it on 2 different length ziplines

And see if it checks out

[feral ice]

is the zipspeed way to high?

[gentle urchin]

Hmm

Dont think so

Check the incoming distance

Print ir

It

[feral ice]

distance between start and player?

or only start and end?

[gentle urchin]

Start and end

[feral ice]

3120

[dawn gazelle]

Wouldn't the "start location" be the same as the actor location? Meaning it's distance is always = 1?

[gentle urchin]

Start loc should really be ziplines point closest to player location

But thats another story

Zipline being a spline would have a node for this

But..

Yiu are righr about the dist part , ish

Not sure why actor loc is plugged in

When theres a vector in from the event

Also

Its distance/speed

Im a moron, tired

[rich granite]

@odd ember @gentle urchin I figured it out.

I had put an Apply Damage node in for testing the widget, but had left it in there after making an enemy, so when the enemy did damage it also triggered the internal Apply Damage node, which in turn triggered the AnyDamage Event, which triggered the Apply Damage node, etc.

[gentle urchin]

3120/200 = 15,67(?)

1/15 would be playrate

@feral ice

[feral ice]

so it would be a static playrate?

[gentle urchin]

No

But i mixed up distance and speed in my formula

Its distance / speed

Not speed / distance

[feral ice]

how i have now

[gentle urchin]

Also, use start and end loc

Dont use the actor pos

For now anyways

[odd ember]

good find. did the breakpoints help?

[gentle urchin]

And test😄

[feral ice]

wow its going SLOOOW

haha

[rich granite]

They did! Probably would have taken me hours or a couple days to find it otherwise 😄

Thanks for the tip!

[gentle urchin]

15 sec to traverse ^^ is slow

[odd ember]

an underused feature

[feral ice]

what should be the next step?

[odd ember]

increase zip speed?

[gentle urchin]

Increase speed ^

Figure out how to input the correct start pos

Add another curve to lerp the z value of the actor ? Many things to do depending on desired outcome

Probably best with some montage and proc jump height?

Never played with details like this before

Just spitballing

Maybe its just a anim transition to grab the line

Then a cycle , just like jump,

And a let go

[feral ice]

yeah gonna save this for tomorrow gotta go to bed

[gentle urchin]

Smart

[odd ember]

tomorrow is a workday 😔

[feral ice]

not for me

im on holiday

😄 thanks for the help so far guys

[arctic radish]

is there a way to disable node grid-snapping?

[trim matrix]

Hello, I am having an issue with the getter and setter with numbers. I have a setup with the setter but when I put the getter in the other function thing it does not work. pic for reference

even when I try to test it with the print string it doesn't print the random numbers that I used for the setter

it displays the number that is determined in the getter

I know I am doing it wrong and want to understand how to fix it

please help

oh

you know

that makes sense

lol

any clue what can go there?

gotcha

but like

yeah, I get that now lol

thank you lol

but

I will show you

I need it to be apart of the multiplication part

would I event start to the branch

then exec from setter to function?

hol up

let me try that

uhhhh

[icy dragon]

Why that stray setter node?

[trim matrix]

ok

so

what I want to do is have the numbers be either multiplied by neg 1 or 1 not 0

so when I set it to zero and it becomes true I want it to reroll till it picks not 0

any time?

lol

I am sorry

I am being stupid

ok

so the object I am working with is a ball

it starts in the middle and I want something to fling it to either side of a board

when the game initially starts that's when this fires off and it has done it's job

I cannot have it hit 0 or else nothing happens

if I have the random integer straight in there then there is a chance of a zero

people say I am difficult to help

it's ok

ok

i will try tthat

it worked

thank you

I didn't need to have another thing after the random bool

pic proof

appreciate thank you sooooo much

[zealous moth]

Is there a quick way to encumber movement in a character? I was thinking of changing the movement mode from walking to whatever and have a smaller speed threshold. Begin/end overlap events in the volume.
Anyone has a better idea?

[odd ember]

make sure that your code is robust enough that you don't get the encumber effect applied multiple times

I'm personally handling this through a debuff system

[zealous moth]

@trim matrix its fps, no need for more anims.
@odd ember i was thinking of having it as a on end overlap also check if still overlapping but good point.
Sinve it will set the speed rather than apply a debuff i wouldnt be worried about stacking

Ty

[indigo bough]

Hey folks, I have this setup where I'm trying to rotate an object (bottom) to face the middle point between two vectors. I've got this calculation together, but the problem is that the rotation of the object isn't quite right.

I want to stop it from twisting around the new forward vector (dotted line). Here is a video to display the issue. The wooden block in the center should always be nicely perpendicular to the direction between the two points (A/B)

You can see that not only does it snap 180 degrees at certain angles, but it also starts twisting strangely. Any idea on how to correct for this?

[wheat delta]

Hey so do y’all know of any advanced advanced articles or documentations on missions and quest tracking with navigation and more, for like missions and then tracking these missions with a wide range of details you can do a very throughl documentation on one?

[zealous moth]

@indigo bough can we see the bp? Gonna guess it uses a construction script

@indigo bough best i can tell is that you get a resulting rotator and that your normal vector either has its angle influenced inversely or you are adding rotators incorrectly. Without bp i can only guess

[indigo bough]

Unfortunately, it's not that simple 😅

This is a skeletal mesh, and I'm doing most of this inside an anim blueprint:

Root is what I'm setting the rotation of the wooden block on, though (you can see that in the first image at the very start)

And the calculation for that Root rot is in the second image

The way it works, is that AEnd and BEnd bones are moved to their target locations (as shown in the video), and then I use their locations in this calculation for the mid-point (which becomes the look-at target for the wooden block/Root bone)

The chain of bones either side can be ignored for this, those are just to account for the bend of the rope (the latter half of the first image)

[brazen stirrup]

guys, im trying to shoot a projectile from a characters wand
im using the wands world location
but the projectile only goes forward for some reason
heres my bp
Image
pls @ me

[zealous moth]

@indigo bough i am very confused by 2 things
Why do you break your rot into 2 and make it up again?
Why do you add your midpoint vector to the AEnd?

[brazen stirrup]

for some reason, if i use a get tranform the initial rotation is off, and if i use get location, it doesnt rotate

[indigo bough]

My understanding is to find the midpoint between two vectors you do:

(A - B) /2 + A

Is that incorrect?

As for the breaking the Rot into 2/and back again, it's not necessary, I was just trying something before this screenshot

[raw karma]

Hi all,

I am using the third person BP but have changed the camera to be first person. I'm trying to figure out how to get my camera to move down when I crouch. I've got the animations setup on my mesh, but the camera doesn't move down when I crouch. All the tutorials I've found are specific to either third person or first person, but I can't seem to figure out how to just get the camera to move down with the crouch. Any direction to a video or forum on this would be sincerely appreciated!!

[zealous moth]

Yeah the +A part doesnt sound right

[indigo bough]

Hmm, fair point, the midpoint is correct, though. It's just the rotation that I'm struggling with

[zealous moth]

@trim matrix dat cat

@indigo bough well the rotation break actually explains why you get a weird result. The Z local is flipping and you built your rota without a z vector so the engine guesses

[indigo bough]

Ahh okay, I did think this, but I can't seem to build a rotation with X, Y and Z 😦

[zealous moth]

@raw karma attach the camera to a bone like the head

[indigo bough]

I still can't wrap my head around quaternions 😄

[zealous moth]

@trim matrix i havent had issues so far. Typically it was my limited aloof mind forgetting a arc cos or something :-P

@indigo bough since you are using anim graph you can actuallyc heat it

You can impose rotation limits to each bone

[final python]

oops accidently clicked blueprint, instead of marketplace, sry

[zealous moth]

I forget the node. Not t computer atm

[indigo bough]

Ahh, Is that the "Apply Limits" node?

[zealous moth]

Yes

And you can limit the bone rotations

It is great for realistic character movements

[indigo bough]

Ahh wonderful, do you know if I apply limits before/after the applied modifications? I don't suppose it matters

[brazen stirrup]

guys pls help

[zealous moth]

Havent done this in a while. I have notes somewhere

[indigo bough]

No worries, I'll do some digging. Thank you for the help! (Also @trim matrix !)

[indigo bough]

You probably want to get the wand's forward vector, and use that. 🙂

[wheat delta]

Ok well then where can I start to learn and we’ll I atleast need something in the next 6 months?

[brazen stirrup]

Did that, but wut fixed it was getting the pawns aim rotation

[wheat delta]

???

[raw karma]

I've got my camera nested in a spring arm which is already socketed to the head, sadly it doesn't work.
What does work is when I look at the ground and crouch the camera goes down, but when I'm looking up straight (normal level), the camera doesn't move at all.

[wheat delta]

No like where do I start

Nvm I will probably just find a basic article on it and somehow build up from it

It needs to be rigged for multi player and can do anything I want example for pick up this and that

And at the begging of the game it has to play a cutscene if it’s a new user

[lost solstice]

what exactly would be the different between running something in the Construction script vs Begin Play?

[young crystal]

Begin play is when you click play

So it triggers immediately

Never messed around with construction script

[foggy escarp]

the construction script is called very quickly in the editor but also on begin play

such as moving while in the editor

[dawn gazelle]

Construction script fires when you place the actor in the editor or when you move it around in the editor.
There's also limitations to what you can do in the construction script. Like begin play you can fire latent events, etc. Construction script acts more like a function in this regard.

[foggy escarp]

also when the actor is changed, via variable

[lost solstice]

ah ok thats interesting. Thanks!

[foggy escarp]

Something i use it for is for editor utilities and tools for development.

[young crystal]

Also if anyone could give me tips on how to use blueprints cause as I said in another channel, I keep having amazing ideas but I never know how to implement them

[marble warren]

have a look

If you want i can help you out.

Do Hits take priority over Overlaps?

[brazen merlin]

they can both happen?

[rich granite]

Yeah, I figured that. Right now I'm having an issue where neither my player pawn nor the enemy pawn are generating Hits on eachother.

[brazen merlin]

they may not because they dont use Physics 🤔

[rich granite]

They'll generate hits from running into the tilemap, but not eachother.

[brazen merlin]

oh, then nvm, they can respond to their collision channels?

i assume both are pawn, both can block pawn, and both have generate hit on?

[rich granite]

So it would seem, here's the player's channels.

And here's the enemy's

[brazen merlin]

their object types are Pawn so they should be blocking Pawn in the Object Responses

[rich granite]

Ah, are Hits only generated when blocked?

[brazen merlin]

yes

[rich granite]

Is this right for making sure its the player that Hit the enemy?

[brazen merlin]

so this is called in the player bp?

[rich granite]

This is in the enemy's BP

[brazen merlin]

getting player pawn works for enemy because the enemy needs to know if they hit the player

but for the player to know when they hit an enemy is not right, but i dont think you need both anyways

[valid grove]

Is there a way to know when a value is assigned to a variable via details panel ? Like a hook to which we can listen to when value changes ?

[brazen merlin]

you can "watch" a variable if thats what you mean, so while the game is running you can hover over it to see its current value, otherwise you could print string it

[stiff raptor]

My current system works fine, but thanks for your reply. I'd use it in the future.

[rich granite]

Okay so here's my scripting for the player damaging enemies. The enemy class inherits from BP_Enemy_Base, but the casting is failing for some reason.

[valid grove]

Not for debugging purpose. How do we validate a data that is assigned via details panel ?

[brazen merlin]

uhhh, i dont quite follow.... isValid?

[brazen merlin]

if it inherits, then it is not the same thing to cast as

you want to compare if this actor has the same parent class and use an isEqual class

[faint pasture]

Can we not BP subclass StaticMeshComponent?

I want a component with a visual element to it, what's the ticket here?

[brazen merlin]

huh?

[faint pasture]

Like how would one pull off a DoorknobComponent, that is, basically a mesh + some functionality

or ButtonComponent, etc

[brazen merlin]

actor component?

ah nvm

i guess ive just been using actors 😛

[rich granite]

Okay, but that's my problem: even with an isEqual class it still reads false when the actor inherits from BP_Enemy_Base

[faint pasture]

wait wtf i guess we can subclass StaticMeshComponent, I coulda swore we couldn't before

[thorn fiber]

Should be purple to check class type

[brazen merlin]

isnt that what you asked lol?

[faint pasture]

I asked if there was a way to do it, because I could swear you used to not be able to

[brazen merlin]

sounds like something too fancy for the early days

looks like you can though

[rich granite]

Still nothing :T

[brazen merlin]

try

sorry, i forgot you are going from child up

[rich granite]

❣️ ❣️

This is greater than 0, right?

[maiden wadi]

Depends on the checking function. But generally yes.

[rich granite]

Did I pick the wrong checking function?

[brazen merlin]

you have is Z <= 0

Z less than or equal to 0

[rich granite]

🤦‍♂️

Er

Wait

[brazen merlin]

they trip me up too

[rich granite]

Yeah, but 0.42 is still > than 0, yeah?

[brazen merlin]

well its printing when it is false

[rich granite]

Right, but I don't want it to be false.

[brazen merlin]

lol, correct

Z >= 0

[maiden wadi]

0.3 is greater than 0.0. So 0.3<= false

[rich granite]

Ugh.

I need food.

[maiden wadi]

Hey. At least you're not ==ing floats. 😄

[shadow crescent]

is it possible to rotate this mesh in my blueprint so I don't need to redo it in modeling software?

[eternal reef]

Did you define the mesh as the root in your BP?
I think the easiest way is to reimport your mesh with modified rotation
(or directly rotate it in the mesh itself)
Otherwise you could add a scene component as the root of your BP, then you are able to rotate the mesh directly in your BP
*By reimport with dif. rotation I refer to the import window of UE, not the modelling software

[shadow crescent]

nice

[shadow crescent]

I appreciate all your tips ... I decided to build again

these are very basic shapes and I want to ensure I get in the habit of doing it right in blender, lol

is it possible to filter this array by the last 2 text fields (arrays)?

[gentle urchin]

if you break it separatly

you can choose which pins to show

[shadow crescent]

that can help me to build an array?

I want to list these items on a UMG

[gentle urchin]

I guess i misunderstood what you wanted

you'll have to do a manual loop to figure out if an array item has the desired values

[eternal reef]

You wouldnt want to retrieve the Category and Tags directly fromt he BuildID I suppose right

If you want to filter based on this information, or am I missing something

[shadow crescent]

well, I plan to group by Category (different buildable object pages), then on each page have separate groups (formed by tags)

[eternal reef]

Oh and the BuildID defines the tags?

[gentle urchin]

each build thingy can be part of several categories, and several tags?

[shadow crescent]

build ID I think defines which mesh is active from my BuildablesDB

I think

this is being tweaked after following a tutorial

trying to build it up 😛

[brazen merlin]

oof

[shadow crescent]

I alwauys see you off when it comes to data, lol

[brazen merlin]

lol that is one oof

that its also by a tut... oof

[shadow crescent]

lol

damn it UE

even when I have created a new asset and not even done anything with it yet, still won't let me move directories

[gentle urchin]

damn big oof
