blueprint

[storm shale]

Like... if the bomb is the only stuff like that in the game; interface def the easiest and most straight forward approach

[warped juniper]

Well not quite

The thing interacting with them is a separate class called blast, with a sphere radius

Bombs create an actor that is a child of it with their own settings and parameters. There are other actors that create other types of blasts

This is because each one has a unique behaviour but tbh, I may end up scrapping them so a single class for each blast will be doable.

[storm shale]

SO blast is parent class.
And then it has child classes for different types of blasts?

You could either detect in blast class what is it that you are interacting with; so the specific blast decides how it wants to interact with players and environment

[warped juniper]

Yeah, but like I said the game might just take a turn in design and there would be a singular type of blast

[storm shale]

OR use an interface

either ways it works

Either way it works, up to you and what you prefer and what's most straight forward for the way you plan on designing stuff

[warped juniper]

Right. Currently the blast checks for overlaps with components based on a tag they have + interface implementation. Then it will attempt to run the event for the reaction

The function just sends the event + a float and a bool

[violet bison]

thanks for everything, I think I know inheritances, but I just need to transfer some variables from a modular component that get casted on to the actors the component is attached to, like the actor components function ran on them
guess it's back to yt tutorials

[warped juniper]

Though I have a small issue with the bombs that isn't game breaking but it still returns an error.
The bomb destroys breakable obstacles, naturally, but then it will try to send the event to them a second time...

I feel this might be because the blast actually has a radius expansion after it's spawned, just to make it match up better with the niagara particle effect

[storm shale]

I mean ye that's just a bug

[warped juniper]

So nothing to worry about?

[storm shale]

I mean; the way you describe it it could be anything; but I don't see how it could be related to what you were asking about; communicating in-between blueprints

[warped juniper]

Yeah... It's just a case of an actor trying to communicate to another that is scheduled to be destroyed

I could maybe make set it to ignore actors it has successfully executed the event ofm but that feels like optimisation for later

[storm shale]

it will try to send the event to them a second time...
First it would be understanding why that is happening; you can know for sure through print strings.

then u just fix that!

If it's not game-breaking you don't need to fix it immediately, but for sure understand why

cuz the why could be huge and smth that will come to bite u later

[warped juniper]

Yeah I definetly want to, since it could potentially cause FPS drops depending on how many times it can happen a tick

Just... a bug to squash later.

I will note it down and go back to it in the future

[storm shale]

When it comes to that.
Just think about how you want designing your 'blasts' to be.
How many will there be; a set amount, or smth that continously gets added.
Stuff like that.

Then you can think of how you want the creation process for these blasts to be so to speak.
For example; you may want to have a couple variables with some parameters; and a couple functions for stuff blasts can do.
So that child blasts can use all of that and making them is ez so to speak.

IF there were only 3 blasts; or 4 types; then best advice would be just getting to it and not overthinking it XD

cuz in that scenario optimizations that will only optimize the development process cannot possible pay off if there's such a short amount so to speak

[warped juniper]

Yeah I perfectly get that

And admiteddly I only needed different subclasses for blasts because I tried some different stuff

For example, a blast with a different collision shape, or a blast that would create more blasts

But trying them out they don't add as much as I wanted and thus may end up getting scrapped, and then I might as well clean up after them

[graceful gorge]

How do I make a delay between each number and another, between 1 to 100 in this example?

[surreal peak]

iirc you can make your own For Loop Macro (basically a copy past of this) and add the Delay node into it.

If not, then you'd need to create the loop manually, by having an Event for the LoopBody, at which end you call a DelayNode (or Timer) that calls the LoopBody again if you haven't reached the MaxValue yet.

[surreal peak]

Yeah I just tested it, you basically copy paste the For Loop out of the StandardMacros Library into one of your own, add a float input for the Duration and plug the Delay node after the "TRUE" ping of the Branch you can find in there.
That will make sure that there will be a delay between each call, despite the completed pin (that's the "FALSE" pin).

I do think this adds an initial Delay though, so you might want to add something that checks if the "LocalInteger" is == FirstIndex if you don't want that.

Tried to clean it up a bit. Despite the Reroute Nodes and the Delay part, this is basically the For Loop Macro (double click the one in your screenshot to see the standard one)

If you want to skip the initial delay for the first element ,you could add this stuff to it

The red stuff. Green outlines are just to help seeing what it's connected to

[graceful gorge]

This is a lot deeper than I expected! I thought I would add a node or two to the series. I'll give it a try. Thanks.

[surreal peak]

Yeah you can try to add the Delay to the LoopBody pin, before the PrintString, but you'll notice, that this won't work.

The reason for that is that the Loop will go through the 1 -> 100 indices in 1 frame, triggering the DelayNode 100 times in one frame, which will simply restart it and you only get one single Delay and print.

If you plug the Delay into the Macro, it will consider the Delay every iteration.

[graceful gorge]

that is what I tested.

[surreal peak]

You will notice that the version with the Delay node gets a Clock Icon, which means it's "Latent" and isn't guaranteed to finish in the same frame.
That will also remove the option to use that node in Functions (which are, by definition, required to start and finish the same frame).

[storm shale]

how do you put the M?

in the icon

[surreal peak]

The M in the Icon?

[surreal peak]

Also.. is that a Ligma joke in your name?

tsk tsk tsk

[storm shale]

ye

[frosty heron]

Macro

[graceful gorge]

https://www.youtube.com/watch?v=Vag2lhosFD8

[surreal peak]

I didn't put that M there

[storm shale]

I went througha breakup

it changed me

[surreal peak]

That's just the Macro doing its thing

[storm shale]

oh ok, mine shows a gear

[surreal peak]

Might be cause I made my macro in a random BP that I had at hand

It's not in a library

[faint violet]

do interface chains complete on same frame [will they hold up the frame]?

[spark steppe]

i'm not sure if for loops with delay should exist... 😄

[faint violet]

actually, wouldnt they be good for spawning lots of object/enemies?

[spark steppe]

i dont think so

if you have an spawner actor, you can also spawn the enemies on tick and change the tick interval

and disable tick/destroy spawner when it should stop spawning

you could also wrap that in a actor component, if you want to put it on static actors and maybe a boss which spawns raccoons to fight you

[faint violet]

maybe it would make more sense if spawning them with a noticeable delay. as it would be time>fps based.
I was thinking pacing out mass objects, but doing it time based to avoid fps drop delay, would probably just drop the fps more as it cant keep up

[gentle urchin]

I think they have their purpose ,

And helps overcome some of the loop issues with bp

Frame slicing is a good principle even in bp

[faint violet]

how does multithreading work in bps anyways?

[gentle urchin]

It doesnt

So there's that

Some plugins allow it tho

[faint violet]

so, all bps run on the same thread? what about inbuilt systems like animation graphs and other graphics systems?

actually lets say I use replication with a sever, wouldnt the server run on a separate thread, even in singleplayer?

[storm shale]

frfr

[gentle urchin]

all bp's generally run on the game /main thread yes ,

some systems use multithreads

animations can use it, if you build your animBP correctly

[faint violet]

hm ok

[boreal laurel]

Hello. Manny Tearson here. Er... Am I allowed to link a YouTube video for what I'm about to ask? Came on here to figure out if the name changed 'Set View Target with Blend'. I'm using the latest UE5 version. If this is simple enough to understand, I don't think I need to worry about the video. Lol.

And yes, complete noob here. 👋

... Kind of weird to find a Bot with the same first name as I. 😅

[lunar sleet]

Better to just ask the question. Not sure what “name changed” follows by a node name means

[boreal laurel]

I mean, I don't see it anywhere. I'm wondering if the name of that node changed or if I'm simply overlooking something.

[lunar sleet]

Nope, still the same node

You’re probably dragging off the wrong thing

[boreal laurel]

Maybe? I don't know. Was just following this YouTuber. This is mine, btw.

I even tried without dragging.

[lunar sleet]

1. Don’t use level bp

2. Right click the graph instead of dragging the pin

Player controller is probably a good place to do it

[boreal laurel]

Alright. Thanks. I'll just dig around and see what's all needed. Though... Player Controller for a Main Menu scene?

[frosty heron]

Set View Target with blend is a function from controller

not camera

[boreal laurel]

Ah. Alright. No idea how that YouTuber got it to work, though. Lol. Been at it for a few hours. 😅

[frosty heron]

It's a function from controller

so pull out your controller

Get Player Controller -> Set View Target with blend

[boreal laurel]

If... you don't mind me asking, where can I find this controller? 😅

Or better yet, is there a guide somewhere that I can read upon?

I found the controller but... I just don't get it. Now I can't add the camera. 🤷

[frosty heron]

Show your attempt with the controller

the function takes an Actor as argument

what are you trying to plug?

[boreal laurel]

I'm just trying to follow the tutorial on YouTube. This one.
https://www.youtube.com/watch?v=JuZVAZPROAM

[frosty heron]

I'm not watching YT tutorial

show your attempt

[boreal laurel]

By dragging.

[gentle urchin]

Gotta stay clear, or else we might get infected :p

[frosty heron]

You can't drag level actor stuff into your blueprint class, the blueprint template exist without a level, hence it will not know the camera you are trying to drop

[boreal laurel]

I'm not that bad, I can promise that much. 😅

[frosty heron]

what you can do here, is to create a variable of type camera actor in your blueprint class

make it instance editable and expose on spawn

drop your blueprint to the world so the world will have an instance of your blueprint class

there set the camera variable to the camera in your level

after that you can use the camera variable

[gentle urchin]

Oooor

Create a global camera manager

And subclass camera with YourCameraBP which auto registers to the manager with something easily identifyable

Like a GameplayTag

TownName.Building.SomeCameraName

Gamestate could hold the manager

If its a one-off thing, manager is ofc not necessary but

The concept is usable for other things too

[frosty heron]

preferably yeah

but prob too overwheling when one doesn't know blueprint coms

[coarse lava]

Quick question: How would I set up a "threshold" for a random float in range? Say I get a random float between the range of -180 and 180. I'd like to have it so that with a threshold of 0 the random float between -180 and 180 would be totally random but the higher the "threshold"-variable would be, the random float between -180 and 180 would be "less random"?

It would be easy if I could get the min/max values straight from the parameter slider range/value range. Then I could just modify those with the threshold. Also, I know I could just set up separate variables for min/max values and then use those in the same way but... the problem is that the thing I'm working on huge number of variables and manually making min/max variables for each variable would clutter the BP a lot. I was wondering if there's any "math trick" to get similar results?

Basically I'd like to find a "math way" to adjust the outcome from "random float in range" somehow (or something similar). Any ideas would be greatly appreciated! 🙂

[boreal laurel]

Lol. If all this was made via Python with UE elements, I'd probably be a god in comparison of now. I lost internet. Will check these options out. Thank you, ColdSummer and @gentle urchin. I appreciate your help.

[frosty heron]

If you know OOP you should know what instances and what class are

[timber basalt]

question for all does the debug for this sphere trace will persist after i build the game ?

or it will remove itself or set to none

[gentle urchin]

Debug is remived during shipping afaik

[iron furnace]

I might be an idiot, but this has worked for me a thousand times before. When checking if the player character is in range to draw a widget, i compare the other actor to the thirdpersoncharacter and if its true, i set the widget to visible. My current issue is this just straight up is not working for me. the overlap detects thirdpersoncharacter0 and sets the branch to false. What am i doing wrong here?

[dawn gazelle]

What you're doing here is checking if the "Other Actor" reference is equal to the "BP_ThirdPersonCharacter" blueprint, which it will never be true as you're comparing against an asset, not a spawned actor instance. One way of correctly doing this is by casting "Other Actor" to BP_ThirdPersonCharacter in which case it'll succeed if the thing overlapping is an instance of "BP_ThirdPersonCharacter".

[fallow current]

I've been working on an animation blueprint for some time and randomly it keeps on spawning these preview instances. How do I get rid of them and how does this keep happening?

[iron furnace]

lmfao i skipped that step, i am an idiot

got it working now, tired brain doesnt always work out

[bold phoenix]

Hello everyone, is there a way to subscribe to an event dispatcher without knowing its existence ? Here's my problem : I have an input action event inside my player pawn and I want to trigger an event inside an actor component attached. However, because this actor component will be part of a plugin it must not be aware of the event / event dispatcher inside of the player pawn blueprint ( in order to prevent dependencies ).

[ruby tendon]

I am using this exact method to clamp my physics linear velocity. However I want the z velocity to be clamped to something bigger. And I was wondering how I can do this. I tried what the description says but I cant figure it out

[woven hearth]

Hey there, I wanted to know. Is there a way to negate a boolean when using the Enhanced input system? IA_Ventilation is bool type, I did try using the negate modifier but it still outputted "True"

[maiden wadi]

Need more details on this. ATM I assume you want basically 0 input to randomize from -180 to 180. And then if a value is at -180 or 180 it will pretty much be -180 or 180? If its at -90 or 90. It randomizes somewhere between -135 and -45 or 45 to 135, but with a scaling favor towards -90 or 90?

[tawdry walrus]

You can get the action value in the blueprint and add "not boolean" node

[woven hearth]

Yea, but I want to only negate the value if the "S" key is pressed. If I do it like you described then I would negate even the "W" key

[maiden wadi]

Simple answer is no. You either need to put the input in the component, or you need to set it up so that the users can simply call a function on the component.

[gentle urchin]

Random(max-treshold)+treshold? And some trick to make sure negative stays negative

[tawdry walrus]

So you can make the type float 1D and make the "S" key negate and in blueprint add check if the action value less then zero and add not boolean node

[woven hearth]

Oh, thank you

[dark drum]

Would anyone have any ideas why this less than node would be false even though the time of day is smaller than the end time? The restrict time span just removes the day and milliseconds.

[gentle urchin]

So if you breakpoint andninspect themz thats really the case?

Logic seem a bit off but guess that depends om what you're trying to achieve

[dark drum]

yea, time of day was 22:xx:xx and the end time was 23:59.

[gentle urchin]

And you're on the false route ?

[dark drum]

Yea

[gentle urchin]

Of the endtime < start time ?

If endtime is 23.59

I doubt its less than start time

Oh right

Mb yes , brain gymnastics

[dark drum]

Yea it accounts for wrapping so if the start was 22:00 and the end was 03:00 lol.

[gentle urchin]

Id prob do that differently

[gentle urchin]

If startTime > time of day then
Duration = end time - time of day

[dark drum]

I'm open to suggestions lol.

[gentle urchin]

Except the wrapping i guess...

Hmmm

[dark drum]

It's some logic I set up months ago but for some reason as started acting up for some reason. 🤷

[gentle urchin]

Engine update?

[dark drum]

No, still rocking 5.1. (Nearing a launch date so won't be upgrading)

Omg!! I've just spotted the issue. 🤦‍♂️

The end time is 23 minutes not 23 hours

[gentle urchin]

if (TimeOfDay >= StartTime)
{
 if (EndTime < StartTime)
 {
 return Endtime > TimeofDay - StartTime);
 }
 return EndTime > TimeOfDay;
}

I feel like this could be a one liner 😆

But it should be accurate and account for wrapping as is

Wrap it in a pure function so it looks nice 😏

[dire frost]

return ((EndTime > (TimeOfDay - StartTime)) * (EndTime < StartTime))*(TimeOfDay >= StartTime);

there, now i gotta take i shower...😣

[mental trellis]

But why?

[dire frost]

that's a really good question

[mental trellis]

Just makes the code much harder to read.

[dire frost]

and i think the compiler would optimise it to something like that anyway?

but i just done for the sake of it.

[mental trellis]

Plus in the original it's not actually returning in all cases, so you can't really start with 'return'...

[dire frost]

well because Squize said it could be a one liner

[mental trellis]

You could maybe use ?! to optionally return.

[dire frost]

yeah i was about to mention it might return a 0 which may not be something you'd want but again...this wasnt meant to be taken so seriously 😅

?

[empty marten]

It wasn't until I read this message from you that I thought you were asking why he was gonna take a shower....

@mental trellis

[mental trellis]

Lol

[empty marten]

You can see my mistake lol

[mental trellis]

It's a good one.

Showering does make code harder to read.

[coarse lava]

Hi! Thank you for your thoughs/suggestions. My initial thought was something similar to gaussian normal distribution so that if the threshold is 1, for -180 and 180, the output would be zero (the average of the two) and if the threshold is half (0.5) it would mostly give some random values between -90 and 90. And if the threshold would be 0 it would be totally random between -180 and 180.

@maiden wadi @gentle urchin

[gentle urchin]

Range = Max * (1-treshold)

I had it right the first time perhaps lol

[coarse lava]

Thank you! That would be much easier to implement than an actual normal distribution using wikipedia. 😄 I'll look into this but by the looks of it, it seems solid. But like you said, perhaps needs a bit of math magic when it comes to negative values.

[gentle urchin]

It'd work the same both ways

But you could also do range 0 to max and randomly multiply by -1 after

Id expect rangw to be -max to max here tho

[barren tangle]

does that node trace a line from the center of my actor. to the center of the target actor?

but after finding the center of the target actor goes 2 times further?

because even like this, i don't feel like it goes from the center to the center

what i would like to do is to trace a line from the center of my actor passing though the center of the target and going a little bit further

and get the purple circle location

[fiery swallow]

https://i.gyazo.com/a01e050e8873c7ea1954706ae73bda91.png

[barren tangle]

thanks but why it's not just 2 positions to uses?

[fiery swallow]

I don't understand your question

there's a start and an end, that's 2 positions

[mental trellis]

Why are you using rotation at all? Why not (location target - location source).normalise * 150 + location target

Or whatever number you want.

[fiery swallow]

I figure there's 100 ways to achieve the same method, find look at rotation -> get forward vector translates the easiest for me

[barren tangle]

my question was why it's not just

start : actor location
end : target location

[fiery swallow]

-.-

because then where are you telling the computer to add the extra distance to get to the purple circle you mentioned

[barren tangle]

but if i multiply x and y by a float it should be the offset that i need no?

is it because the world position bring negative value as well

and my calcul is not correct anymore?

[fiery swallow]

it's really just a math problem so unfortunately I cannot explain why your method doesn't work the way you think it should

I believe it has something to do with the way you have to consider a 3d world

[barren tangle]

but i set the Z axis to 1 to keep it on the same level of the target z position

so it's more like a 2d world

[visual ember]

still, position of actor is relative to world origin, not to the other actor

[fiery swallow]

yeah but I meant more so in the world of relativity. adding a vector + vector

oh

yeah what mars said

[visual ember]

so you were initially extending other actor's position vector, not vector from A1 to A2

[barren tangle]

ok

[visual ember]

take pen and paper

[barren tangle]

got it

[visual ember]

draw it out, name your vectors

math is powerful. embrace it

[barren tangle]

i was drawing a 2d axe with 0,0 as center and target actor at 10,10

and by multiply on that draw it was correct

[fiery swallow]

on another note. This was the method Daekesh mentioned, which also worked just fine
https://i.gyazo.com/7a35fa586a0e9824261f381e84535696.png

if you don't want to bother with the finding look at rotation stuff

his is objectively better actually

[gentle urchin]

GetUnitDirection^

[fiery swallow]

oh my god whatever xD insert 97 more ways to compute this problem

[barren tangle]

yes that one is good 🙂

[fiery swallow]

they're both fine, his might save you like 0.002ms though

[gentle urchin]

Moxie, strive to be excellent !

/jk

[barren tangle]

hahaahc 😄

ok thanks

[visual ember]

I would say use the most easy to understand solution. so when you get back to it after 6 months, it doesn't take too much hair off your head

[fiery swallow]

https://i.gyazo.com/6ed76502aa94c63f5a34ebacff97353a.png
this one made me laugh a little

It's a straight upgrade from the method I used

[gentle urchin]

😅

[dull hare]

Hi, applied force to door but without checked Accel Change they don't work, I already tried to lower mesh mass, disable physic constraint

[dark drum]

Is the door set to simulate physics?

[dull hare]

yes ofc

[eager thicket]

is there a correct way to close down a widget to ensure it isn't interacted with by the player? (for instance, pulling up the options menu and then closing it again - in the main menu)

like do I hide + deactivate or something

[gentle urchin]

Collapse usually does the trick

Revert any game mode changes and cursor visibility if necessary

[spark steppe]

which is where you begin to write a wrapper around that whole half assed UMG/UserInput/Cursor nonsense

[drowsy steppe]

hey guys, i'm getting an "accessed none trying to read property Timeline" do anyone knows how can i fix this?

[gentle urchin]

Make sure your Timeline component reference is valid

[drowsy steppe]

i tried putting it in another actor and it works, but in the other it doesn't, but i set them up the same

[ashen tide]

Hello everyone, I hope it is the right place to ask, I am trying to incoporate the motion matching from the GAS project in my character and I have a couple of issue, first when I use some animation like crouching I get extreme clipping into wall, from what I understand it is because of the root offset function, and I indeed don't have any clipping when I disable it. I want to know if any of you managed to fixed the clipping issue ?
Thanks 🙂

[young meteor]

Anyone here good at math with vectors?

I'm trying to set up a function to detect if one actor is facing another actor straight on with a tolerance of "Front Angle Degrees" specified in degrees (not radians).
I've set it up like this, and it seems to work but it has surprised me so many times that I'm a bit confused. Can anyone confirm or debunk please?

(Dividing by 180 instead of multiplying Pi by 2 first and then dividing by 360)

[gentle urchin]

Dot vector

[gentle urchin]

There we go

[rugged wigeon]

also it looks like you're setting yourself up to try and get the angle between the forward vector of two actors, which is wrong

[gentle urchin]

Wait, does that work?^

[rugged wigeon]

You don't want the angle between 1 and 2. You want the angle between 1 and 3

[young meteor]

Normalize does what? Just gets a vector 1 long with the direction of the original vector?

[rugged wigeon]

yes

[gentle urchin]

Forward vs target direction vector

Direction vectors are normalized by default

[rugged wigeon]

also true, but he's wrong for using two forward vectors to begin with

[young meteor]

I don't understand why I want it between 1 and 3 instead.

[gentle urchin]

So
Angle = ACosd(Dot(ForwardVector, DirectionVector))

[young meteor]

I don't really care about their location reletive to each other. Only if they are facing each other or not (with the tolerance described)

[rugged wigeon]

If you're standing in front of me looking to the right, we are looking 90 degreess different directions. But you're 0 degrees in front of me

[gentle urchin]

DirectionVector = (ActorLocation-TargetLocation).Normalize()

[young meteor]

yeah. So the 90 degrees is what I'm after

[rugged wigeon]

I really don't think it is. If you're standing in front of me, and we're both looking north, then we are not facing each other

"Are we facing each other" is asking about two different peoples perspectives

you need to check if BOTH actors are facing the other unit

[gentle urchin]

Facing would be Dot = -1

[young meteor]

I'm not convinced what you are saying is what I need.

I specifically care if the two actors are facing each other.

[rugged wigeon]

then you need to check if A is facing B AND is B facing A

[young meteor]

I tell the player shooting an enemy from the front deals more damage.

[rugged wigeon]

it is not a single angle difference

then you're phrasing your question wrong. What you want to know is whether two actors are facing the same direction. Not whether they are facing each other.

[young meteor]

I don't see why it would not be a single angle difference.

[rugged wigeon]

then you're phrasing your question wrong. What you want to know is whether two actors are facing the same direction. Not whether they are facing each other.

in which case just use my function above with the two forward vectors.

[young meteor]

Facing each other like this. Not sure if I'm writing it wrong.

But if the above is the actual situation I want a True statement from my function.

[rugged wigeon]

"Are we facing the same direction" is not the same question as "Are we Not facing each other"

[young meteor]

But none of those statements are what I'm after. I'm after "Are we facing each other".

[gentle urchin]

So... you wanna dot product your forward with their forward

[young meteor]

Your second statement could be true in that case, but could also be a 90 degrees situation.

[young meteor]

Right. Is what I was thinking too.

[gentle urchin]

-1 would mean extra damage

The same math works tho

[gentle urchin]

Just Abs for the angle check

[rugged wigeon]

These two guys are facing the same direction

[young meteor]

Agreed

[rugged wigeon]

If you want to explicitly check if two actors are facing EACH OTHER

You need to check is A facing B and is B facing A

[young meteor]

Don't agree. Or maybe I indirectly agree and would just assume it is done in 1 math operation.

[rugged wigeon]

well, you're wrong

[lost steppe]

Try using dot or dot product

[gentle urchin]

1 operation does the trick

Dot(MyActor.ForwardVector,TargetActor.ForwardVector)

[rugged wigeon]

That fails my picture where both are facing left

[gentle urchin]

Both facing left means 1

1 facing left and one right, means yoi're not hitting them

And thus this chevk never happensn

The chevk only happens when you hit them

[young meteor]

Right. That is basically this first part of my function right?

Now I just need the flexibility of being "off" by X degrees (not in radians)

[gentle urchin]

So a precondition is that ome of them guaranteed looks at the other

The Dot product will be -1 if you're aiming at their front

[rugged wigeon]

if you want to magically assume that at least one of them is facing each other then sure

[gentle urchin]

When you aim at someone, you must

[rugged wigeon]

just pipe the dot through acosd

[gentle urchin]

So its safe to assume that here

Itll be negative angle but

[young meteor]

Ah okay. Good point. It's a tower defense so my own tower will indeed always be facing the target. (they rotate)

[gentle urchin]

Abs solves that

Altho you need to know that the angle was negative

Or is negative

So perhaps not abs it

[rugged wigeon]

ACosD will convert the dotproduct of two normalized vectors into the unsigned angle difference between them

[gentle urchin]

So we need the resulting product checked first

Making sure its negative

[young meteor]

what does an "unsigned angle" mean? English is not my first language sorry.

[rugged wigeon]

a signed number is marked as positive or negative

an unsigned number is not. So it won't differentiate between 5 degrees left or right

[gentle urchin]

Front or back either

[rugged wigeon]

front or back is effectively just a question of whether the degrees difference is greater or less than 90 degrees.

which is 1:1 with whether the dot product is positive or negative

So just to recap, since you are assuming that A is facing B. You can assume that if A is facing the same direction as B, that A is aiming at B's back. And if they are facing opposite directions, that A and B are facing each other.

Get the angle between A's forward vector and B's forward vector as I showed you.

You can do your backshot logic with that angle difference. If the angle is 0, they're facing the same way and A is aiming straight at B's back. If A < 90 it's at least a back shot in some form but it could be a very steep angle.

[gentle urchin]

They want the angle to be atleast 180-treshold

But you're right. Yupp

My brain is fried

[young meteor]

Thank you. So you showed the ACOSd node. So I could do it like this?
This would mean they are what I call "Facing each other" within an angle tolerance of 20 degrees?

[rugged wigeon]

no abs

its going to be a positive number regardless

[gentle urchin]

= 180- degrees

[rugged wigeon]

that's what you're doing right now, and it's probably ok. But 20 degree radius is a little small. I would bump it up to 45 maybe

[rotund barn]

is there a way to sort a float array? every solution ive found requires adding them to a new array, but i need them to stay in the same array. (more specifically its a structure array, but will be sorted by a float it contains, but thats not a problem)

[young meteor]

But that is a flexible parameter that can be modified by the player.

[rugged wigeon]

yes, I'm just saying consider a bigger one so it's easier to test.

[gentle urchin]

You add it back to the original array

[young meteor]

He/She will at least know it is 20 degrees.

[young meteor]

ah, okay

[rugged wigeon]

to be clear it's 20 degrees either way. so a 40 degree window

but that's still smaller than intuition would tell you.

[young meteor]

Think ChatGPT confused me. Looked like opposite direction would be in the negative

[rotund barn]

i want to scream rn. WHY DIDNT I THINK OF THAT. but thank you sir

[young meteor]

right

[rugged wigeon]

Well that chart is irrelevant because you're piping your dot product into another function now, ArcCos

[young meteor]

Something is backwards. I'm getting close to 180 when trying to get a "head on" or "Facing each other" angle from that function:

[gentle urchin]

= 180-20

If 20 is tolerance

Or 180-50 if its a 100 degree window

[rugged wigeon]

ugh, hold on

this is the degree difference in the facing directions of the two units:

[gentle urchin]

0 to 180

[young meteor]

Right. So 180 - X (tolerance in degrees) like Squize suggested would be the solution?

[gentle urchin]

Yepp

A for effort tho

Its good to know why it is like that

[rugged wigeon]

Think carefully about what you want to do. Because the answer probably isn't asking "am I facing them". If you say your threshold is 45 degrees to determine if someone is facing another person; then you'll say you're "not facing them" if they're 50 degrees.

That's not a great definition for a "back shot". Because you're not even behind them.

[tiny monolith]

why my editor's language changes and not my game's

[young meteor]

Right. I get your point.

[young meteor]

Ah, got to be a "greater equal" sign too right?

it's less than right now.

[gentle urchin]

If you want a "facing" shot, yes

[young meteor]

Sorry you could not see that in the screenshot 😄

[gentle urchin]

Facing would be >= 180-tolerance
Backshot would be <= tolerance

[young meteor]

Right. Massive thanks to you both.

[gentle urchin]

Side shot would be anything else

[young meteor]

And the order of two vectors does not matter to be clear?

Forward vector A Dotted with forward vector B is the same as B then A?

[gentle urchin]

Yepp

[young meteor]

Thank you.

[olive yarrow]

Anyone got an interact widget/interface i can steal? Mine occasionally wont trigger anything when firing and if im sprinting and touch something interactable im simply unable to interact 🤦
At this point ive messed with my functions and widgets enough i probably coulda just make a whole new interaction system

[gentle urchin]

Isnt it just trace -> hit -> interractable?

[olive yarrow]

maaaaaybe.... at this point my brains starting to fry but im too stubborn to take a break

[surreal peak]

I feel like your can interact function should return a Boolean or not? And actually be used while using the actor

[olive yarrow]

Just a simple canInteract?

[loud tree]

Yes

[olive yarrow]

lemme see if i can't wrangle something outta this smooth ol brain with a bool

Interacting seems more consistent (so far) but im still having some issue while sprinting into interactable objects....

[wild pumice]

So I believed my journey to achieving frame independent physics would be a simple one. But now I'm in a rabbit hole of UE4 sub-stepping and UE5 Event Async Physics Tick. I'm finding it hard to find resources on what the later is. Can someone help me find explanations on how to properly use the node "Event Async Physics Tick". Im more confused now than when I started trying to use frame independent forces to move my vehicle.

[loud tree]

Disable sprint while this bool is active is one possible fix

[gentle urchin]

you're struggling a bit if several interactables are nearby

then you'll be deactivated, while still having interactable objects nearby

you'd want to store them all in some array

and check the array's length before deciding not to interact

as for which one to interact with you'd do some magic with the listed interactables, using some dot product of the direction vs view direction and decide from there

so it's mostly

OnOverlap -> Implements Interactable ->  Add To Interactables
OnEndOverlap -> Remove (Interactables) 

Tick (or some function of move/rotation) -> Loop Interactables -> Pick the closest one to the center of the screen/aim direction

[queen vault]

Is it ok to use tick for something like a projectile always rotating by a certian degree to give it a spinning effect or should I set it up in a different way?

[mental trellis]

Yes

It is perfectly okay to use tick for things that should happen every tick.

That's what it's for.

[queen vault]

Ok I'm just making sure. I know using tick isn't always the best option.

[mental trellis]

If it's abused, it's bad, for sure.

[queen vault]

Got it. Thanks!

[olive yarrow]

There's gotta be a dumber way 🤦🏿‍♂️ though i also need to get better

[gentle urchin]

if you're using sphere overlaps, this is about as dumb as it gets without having major issues

otherwise you'll have to always guarantee that no two interactables ever get close to overlap at the same time

[vernal lotus]

why is the async load causing so much stutter?

as soon as I try to load 5000 transforms it chokes

[olive yarrow]

fair, thanks Squize. Any chance youve got a visual tutorial for such laying around in the memory banks?

[gentle urchin]

Hmm... I used to do

i can slap together an example i guess

[olive yarrow]

Please visual learner, arguably really need a functioning interact system to continue

[gentle urchin]

overlaps just adds and removes from the array

[olive yarrow]

bare with me - my first project was SOLELY using widgets so it was pretty easy...

Is this in my player or my ParentInteractable_BP?

with my horrid current set up it seems to be a-okay if im looking to sit - but once its an NPC proper it starts pooping the bed

[gentle urchin]

this would be in the character, assuming the character has the interaction collision volume

[olive yarrow]

The interaction collision WAS on my player - but im open to changes

would you recommend starting my interact system fresh?

[gentle urchin]

I'll leave that up to you 😛

the scoring function

[olive yarrow]

at this point i probably should, my brain is STRUGGLIN to imagine the fix up

[gentle urchin]

added a shortcut in-case there's no sorting necessary

messed up the order

its from us, to them

result

[quartz quest]

Is there a (functionally correct) way of changing between default pawn classes in game? Like if I wanted a first/third person hotswap?

[olive yarrow]

😵‍💫 what if uh, what if i never have interactable objects near each other

f*** nvm,. the chances or two villagers passing eachother and the player is too high

ok i gotta start from scratch 😦

[gentle urchin]

the rest of the logic can prob be the same

so its just thse 3 small things

overlap -> add to array
endoverlap -> remove from array
tick -> check best interactable

[olive yarrow]

i wish we could speak with thoughts and imagery

human conciousness limitations

though i did figure out the sprint issue is cause i had it on Triggered not Started. Rookie mistake.

[marsh sonnet]

Prob an easy question for an experienced person but I am a newbie: I am making a beat em up and I don’t want my villain parentage to get too complex, so I want different parents based on if they’re melee or ranged attackers—but for my hero to hit, I have them casting to the melee villain blueprint, so now that I’ve added ranged villains, I’m confused as to how to do this—cause I want hero to be able to hit any villain

[loud tree]

A couple options I can think of

1. Keep them under the same parent. Separate damage code by booleans or something if you want it to be different and create individual programming in the children.

2. Use interfaces

[timber crystal]

I would like to send something to the level BP_interface, but does anyone know how to have the level as a variable? Is that even possible?

[dry sleet]

What do you mean by 5000 transforms?

Actors? Instances?

[vernal lotus]

instances for grass blades

a hism

[dry sleet]

Do they have collision for some reason?

[vernal lotus]

no collision

[dry sleet]

5000 instances shouldn't be a problem at all, but if they're being added to the physics scene it would be a different story

[vernal lotus]

adding or batch update work just fine

it's the async that's the problem

[dry sleet]

Hm.

Shouldn't even have an effect in my experience, pretty sure adding a ISM isn't time sliced to begin with.

You'll have to verify with Insights then, I suppose.

[vernal lotus]

it's loading the data from disk that's the problem

I could do nothing to the array after it loaded and the hitch still happens

[surreal peak]

No, I mean your Interface call. What does that even do? You call "CanInteract" on the Interactable.

[hidden rampart]

Is there a way to manually call a drag and drop after clicking?
I need to have the item widget created and attached to the cursor when clicking on an item in the world, but It doesn't seem to be possible to create drag and drop operation without triggering OnDragDetected and I couldnt manage to manually trigger that.

[mild ice]

Instead of changing the pawn class, you could add a third person skeletal mesh component that is invisible and toggle visibility on/of between the first person skeletal mesh and third person skeletal mesh when switching perspectives. Many games do this now because you can do cool things like displaying the shadows on the invisible third person mesh while in first person.

nice Shart pfp btw

[quartz quest]

Do you think it'd work the same in VR? Like being the character and transitioning to a third person perspective for some scenes?

And thanks! BG3 has amazing facial rigging.

[mild ice]

If it's not for gameplay then what I said doesn't apply. Look up some vids on using Sequencer to create cut scenes.

[haughty snow]

look for some input on execution for a dialogue system. my end state is a fixed size dialogue window where the NPC dialogue and player responses are populated. the text would flow from bottom -> top as new responses are added. I'd also want the movement of the text boxes to be smooth rather than jumping up positions. Is this something I should do using a vertical box, for example? Or do you think I should make my own container that animates Text objects directly?

[olive yarrow]

I tried to figure that out.
I thought I had migrated my interact system from Campfire Stories prior file corruption - but now I'm doubting it. Can't even find any recent tutorials having been watched so I'm genuinely stumped as to where my interaction system even came from

[quartz quest]

It is for gameplay! I'd assume you'd just hide the not active mesh, but would you just have like a "InVR" bool to toggle the different gameplay?

[bold wedge]

Anyway to hide an event dispatcher from the details view, they show up as buttons?

[lilac hill]

I'm having a hard time attaching a player to an object using a skeleton mesh rope. It has bones and physics etc. Which all works great.
I spawn the rope, set physics constraints from the player to one end of the rope, and set a physics constraint for the world attachment object to the other end of the rope. I am physically restrained as expected, however, the end of the rope that is supposed to be attached to the world object, is just attached to the world at the tip where it spawned.
I've tried to do "attach component to componenet" or other variations without any luck. The top end of the rope does not want to go where i want it in the world.
Is there something obvious i have not tried?
Here with a fancy illustration

[grizzled beacon]

how can I know from an animgraph when an animation is over? 100% played?

[plush hinge]

When trying to reparent a BP from original to a duplicate of that original, I am getting this:

Can't figure it out for the life of me. I feel like I'm close, yet so far -.-

Hello guys i am trying to get my character on the motorcycle but when he plays the animation the character stays on the position

how do i get the character to move with the motorcycle ?

wrong video sorry

[inland walrus]

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetGameData_SaveGameData". Node: Load Player Skill Tree Graph: EventGraph Function: Execute Ubergraph WB Skill Slot Blueprint: WB_SkillSlot

anyone know how i go about fixing 'access none' ? seem to have this issue after migrating

[fiery swallow]

You tried to access a reference that didn't exist boss

[empty marten]

Remember what I said about Accessed none.

[fiery swallow]

You Need to load your save game first

And then cast it to your save game object

And then save that variable and use it

[empty marten]

You might need to use AttachActorToComponent instead of attach actor to actor unless you want to reference socket bone names and attach instead.

[inland walrus]

I'm not sure how to go about it, I've been trying for hours and can't hack it

[leaden sail]

thank you

[empty marten]

Also use the Pelvis socket instead of left thigh if you are lol

[inland walrus]

It all works in the other project, it's when I migrate it to a different one it's not working. So I don't think that I need to change the nodes

[empty marten]

Are you referencing the player character btw?

[empty marten]

Then you're forgetting something.

[leaden sail]

Ive made some progress

I have created a seat socket

[inland walrus]

I've checked mate, I am comparing both projects side by side and they look identical

[empty marten]

At least it aint my code you broke lol

[inland walrus]

xD

[loud tree]

Have you referenced your output log? Not the message log.
Another thing would be to run debug to see what's happening.

Also would be beneficial to post pictures of the code that's failing.

[hearty lake]

Hi, Im a bit lost but very interesting into learning how to create a tiny but modular(such as placing objects, biomes andbeing walkable) planet (Like the tech-demo/game by Oskar Stålberg called "Planet", but without auto generating tiles), anyone got some tips or pointers where to start, Voxel plugin or something else, trying to create this using Blueprints in UE5.4. Thanks in advance.

[chilly geyser]

Hello, Im trying to follow this tutorial :
https://dev.epicgames.com/documentation/de-de/unreal-engine/respawning-a-player-character

But I cant figure out how to get the right variable type for character

[undone bluff]

what's the issue

[chilly geyser]

i can find the right variable type

[undone bluff]

just for the record, strictly speaking the type is a pointer, you want a variable for storing a reference to the ACharacter class (the A for Actor prefix is left out in the engine)

unless you have made another class that is simply called Character (not advisable), that is it

oh are you concerned about the icon

[chilly geyser]

yes

[undone bluff]

I have no idea why but Unreal Engine is just inconsistent like that sometimes

don't worry about it

it doesn't show up for me either

if it gives you confidence it does have a tooltip when you hover over it

[chilly geyser]

So I want object reference?

[undone bluff]

yep

[native vector]

Anyone know how to tie the opacity of a widget to the player's health? I feel like its simple but I can't find anything helpful online

[undone bluff]

you want a reference to an instance of the character class so you can specify which character to respawn by reference

[chilly geyser]

object refrence or class refrence?

[chilly geyser]

can you show the widget youre trying to change the opacity of?

[undone bluff]

get the health and divide it by the max health that will give you a range for 0 to 1

[native vector]

yeah im actually not home right now but its a widget bp with a simple red vignette png anchored to the whole screen

[native vector]

in what context? im sorry im still kinda new and also a little stupid

get the health where? in the player bp?

[undone bluff]

wherever it is

[native vector]

i need to bind the opacity somehow, right?

[undone bluff]

ah right the binding thing in widgets

[native vector]

i mean i assume i need that, i dont really know

[undone bluff]

yea you could just cast to whatever holds your health and grab the variable there

[native vector]

but the opacity binds to a function, not a variable

[undone bluff]

that doesn't really matter

but I'd discourage the use of them as they are a pain to debug and super unperformant

the bindings update on tick

[native vector]

how would you do it then?

[undone bluff]

https://dev.epicgames.com/documentation/en-us/unreal-engine/driving-ui-updates-with-events-in-unreal-engine

[rotund barn]

im slowly going insane, if i manually type the string into the struct, everything works as its supposed to (its for an UI element that displays nearby NPCs names above their heads), but if i get it from the input of the function (that i confirmed works as seen by the print string there), its not working/giving its value to the struct

[native vector]

i understand how to get it to tie in with the progress of a bar, but how do you tie it to the opacity?

[undone bluff]

(example 3)

[native vector]

oh i see, alright cool

[undone bluff]

the progress of a bar is a parameter of the bar class, the opacity of your image is a parameter of the image class

it's really the same thing

[undone bluff]

got a whole function just for setting the opacity

[native vector]

so i need to get the health and plug it into the "in opacity"?

or wait i need to divide right

[mellow pike]

so im creating a dynamic material instance to set the color of my mesh, right now its only effecting 1 of the 4 categories, while setting up some pint strings to get to the bottom of that I notice the instance count keeps going up ?

am i at risk of stack over flow doing this ?

[waxen fog]

How can I get UE5 to work with PlayStation 4 controller?

[undone bluff]

your current health divided by the max health will give you a decimal percentage value from 0 at no health to 1 at full health

opacity too is a float with 0 being fully transparent and 1 being opaque

[empty marten]

How are you creating the material instances?

[empty marten]

If you are consistantly creating material instances, eventually you will run out of memory.

[empty marten]

Either use a USB cable or pair using bluetooth to your computer.
Install controller drivers
Enable input from the controller in your input settings in Project Settings
Setup your input mapping
Test
You should be good to go.

[mellow pike]

its creating a new one with on value change (on slider calls)
how might I change that to over ride the last instance instead of making copies ?

[empty marten]

When you enable the input from the controller, check UE5 is picking it up. Normally driver install is required for that. DS4Windows is normally the tool for using PS4/PS5 controllers on Windows PC. Assuming you're using windows?

[waxen fog]

It seems like I need to get this plugin called DualShock for windows

[empty marten]

OK. So the Set Mat Color, is that being executed from an event tick?

[waxen fog]

Yes

[empty marten]

That's DS4Windows....

[undone bluff]

just... don't create anymore

[empty marten]

DS = Dual Shock. 4 = For. Windows = Windows lol

[mellow pike]

Yeah it's call when moving the slides of the first screen shot

[undone bluff]

you have a stored reference to the one you made and are setting this parameter in it

just set the parameter

that's all there is to it

[empty marten]

So like Scaith said, you need to stop calling the function otherwise it will just constantly create more instances.

[empty marten]

I've not used DS4Windows but heard it is just a download and install software so straight forward.

[mellow pike]

Ok I see so I would just make the current mat in a start or constructor and just refrance that when needed on the slider change

[waxen fog]

Ok sick! Hopefully i dont have to create new mappings and it just works with regular gamepad mappings.. I’ll lyk how it goes

[mellow pike]

Well I will need to rework to other functions first then

[undone bluff]

yep

[mellow pike]

Thanks

[empty marten]

Well I'm heading off to bed so won't see your message until tomorrow XD

[waxen fog]

Ah alright goodnight! Sadly it’s not working out the box

[frosty heron]

Have a variable of type dynamic material instance,

Whenever you want to access it, check if it's null. If null create dynamic material and set the return value to the variable (object ref).

If already valid, simply get the variable and set the value.

Or create one and apply to the material somewhere and when you want to change the value, simply get the variable so you are editing from the same ref

[undone bluff]

thorough explanation, only thing I'd add is to place the reference, right click > convert to validated get

[chilly geyser]

Anyone know why this crashes UE

[lunar sleet]

Where is this code, what bp?

[chilly geyser]

Trying to setup a respawn when falling too far, every tutorial ive tired or help ive looked for hasn't worked yet

[lunar sleet]

Answer the question

[chilly geyser]

Guess I didn't understand, BP_ThirdPersonCharacter

[lunar sleet]

So, your code says “when the player character gets destroyed, try to get the player character, destroy it, and run some more logic on it”

[chilly geyser]

Thats the only way that let me compile it, when i delete the destory actor part and try to connect the logic, it crashes

[lunar sleet]

I guess you didn’t understand again

[chilly geyser]

Maybe not

[lunar sleet]

Did you read the tooltip for Event Destroyed ?

[chilly geyser]

yep

[lunar sleet]

Ok. So you’re trying to destroy something that’s already been destroyed

[chilly geyser]

no

[lunar sleet]

No, that’s what you’re doing.

[chilly geyser]

When i remove the second destory

it crashes

[lunar sleet]

I mean you could have bp corruption too for all I know, but at this point I would get rid of that logic entirely.

[chilly geyser]

this is what im trying to do, its not working

[lunar sleet]

That ref is not connected to anything

[chilly geyser]

I cant ref third person character, idk how

[lunar sleet]

Your target needs to be a Player Controller

The nifty little text under the node name that says “Target is…” tells you what to plug in

player character != player controller

The latter is what controls the former

[chilly geyser]

following tooltips

crash

[lunar sleet]

Ok

This code runs on Destroyed which means it prly no longer has a player controller

Try to get player controller (with no target connected) before destroying it, and promote that to a variable

So that it is cached prior to it no longer being there

Then use that saved controller as the target for your possess with a simple GET

[chilly geyser]

! Thank you! This fixed it !!! -

so it was crashing because it was refering to a player controller that got destroyed?

[lunar sleet]

Well you didn’t quite do what I said but removing the target from get player controller was the right first step

[chilly geyser]

nevermind, it crashed again, lol

[lunar sleet]

Well the code wouldn’t compile because you were using get player state to get the controller which is wrong

[lunar sleet]

Try remaking the char bp altogether, you may have some corruption

And also restart PC for good measure

[chilly geyser]

Ill try to restart first.... brb in like 10-15...

[lunar sleet]

As for what I had said, you still need to replace the Possess target with InitialPlayerController

On a side note, it might be easier for you to just turn the visibility off and on (and setting actor location to the desired xform in between the 2) for the character rather than trying to destroy and respawn it

[chilly geyser]

Still crashes when i try to compile it 😢

[lunar sleet]

Try it in a different character class

If it compiles fine, then this one is corrupted

[chilly geyser]

Can I create a new project and merge the BP_ThirdPersonCharacter over to override?
Edit : Migration

[lunar sleet]

If you migrate a corrupted asset you will likely encounter the same issue

[chilly geyser]

From a new project

[lunar sleet]

Oh, yeah that’s probably fine but I doubt it lets you overwrite directly, I can’t rmbr tho. It might just create a _1 duplicate or such

[chilly geyser]

It let me and asked to override

Im thinking its something specifically with that code thats crashing it

Im going to try on a brand new project

yeah, this crshes it even on a new project

[lunar sleet]

Well normally you shouldn’t run any logic on a bp after calling Destroy, so it’s likely the Event Destroyed event doesn’t let you run much logic on it

Try what I said as an alternative

#blueprint message

[chilly geyser]

Tried to read what you put a few times, I'm still having trouble grasping it. I'm not trying to destroy the actor, I'm trying to run logic when this happens

[lunar sleet]

I’m saying don’t destroy it

Just fake it

[visual ember]

what about this. turns Kill Z off and uses custom box collision
https://www.youtube.com/watch?v=DH-O_d9N3K4

might be better than messing with actor lifecycle with limited engine knowledge

[chilly geyser]

Found something and started reading on it. Theres something called FellOutOfWorld the overrides Actor destroyed. I cant find it anymore. I might just take your suggestions but I wish there was a better way to do it.

[lunar sleet]

No need to destroy a char when it falls through the map, just teleport it back up

[chilly geyser]

Is there a way to do it off of the "kill z" in world settings so I don't have to use a volume?

[lunar sleet]

Maybe. I haven’t checked

[chilly geyser]

Not Ideal... But No Volumes...

[spring magnet]

Anyone have an idea on how you can divide the blueprints of a Game Instance between separate classes?
I have multiple people on a team who prefer blueprints, and they will all be working on systems that reside within the Game Instance. It would be nice if I could encapsulate them within UObjects or something inside the Game Instance, but UObjects don't have world context so they're quite limited.

[frosty heron]

The answer to that is Game Instance subsystem. It is cpp only unfortunately.

Having multiple GI, with each doing a separate task is fairly common. I have game instance for loading screen and for saving.

With blueprint only however you can only have 1 game instance

[spring magnet]

I have seen people derive a custom class from UObject with a custom implementation for satisying the World Context problem, and then that allows them to use their own UObject without the limits. That sounded tempting, but I've heard it's a bit finicky.

[gentle urchin]

Or Components?

Should just work

@spring magnet @frosty heron

[spring magnet]

The Game Instance can use Components?

[gentle urchin]

Sure, why not

Unless

Wait it might not

Because of it not being an Actor

Yepp thats the case, my mistake

Subsystems it is

Or the UObject singleton path i suppose

Which reminds me i probably should stray onto the subsystem path at some point in the not so distant future..

[violet bison]

how do I fire event in owner (spawner) from children (spawned actor)?

[gentle urchin]

Dispatchers

Owner spawns child -> binds to childs dispatcher

Child simply calls dispatcher

Owner knows what to do

[brittle raptor]

hello. im trying to set the boolean as false and pass the variable to animation bp. how do i do that?
im using paperzd and it kinda confusing me here

[gentle urchin]

Wouldnt you do this in the animbp directly?

guess i'd do a timer or just do it on tick tho

Tick -> isMoving?
-true> reset IdleTime
-false> accumulate IdleTime

[surreal peak]

Well, one step would be actually using the SetTimerByEvent node. Cause you aren't atm.

[frosty heron]

Adding to what exi says about you are not even using the timer ( look up on how to use timer, you don't have anything connected to the event pin ).
You should never pass anything to your anim blueprint. It goes the other way, the anim blueprint reach its owner and read its properties.

[violet bison]

could there be any circumstances that the client and the server replication fk up the outcome of the code?
it is programmed to do only once (for each instance, which I had 3), and then when I print strings both client and server
how do I set that only server/which client should run the blueprint?

this actor should destroy itself so there after dying so there should be no 'you shouldn't see this' or negative digit hp right?

[frosty heron]

You can filter with is locally controlled / switch has authority / is server, etc etc depending on who needs to run what.

Only server should handle destruction of replicated actor

Client have no business calling destroy on actors that is replicated from server

[hollow bane]

quick boolean question: when i have 4 conditions that all have to be true for my branch to go on why can i not just use three AND boolean Bps?

somehow i get a false statement

the individual and give me true tho

[brittle raptor]

ooh i see
sorry if my question sounded dumb im pretty new to ue after trying to migrate from unity
after some small testing, yeah i needed to have the animbp to read the variables instead

[hollow bane]

i just saw i could add more pins to the AND but didnt help. also dragged in the bool values to get them but didnt also help

any help?

[frosty heron]

What you are doing here make no sense at all

TLDR do not cross pins

Don't do this.
2) Get the variable for the and Check

[frosty heron]

example if P1LeftActive and P1RightActive then fo X

[hollow bane]

i want all four variables to be true to trigger the variable

if only two are active it works

regardless which player, but if i mix the inputs from the two players it doesnt

[frosty heron]

debug, make sure all the bool are set to true

[cosmic dirge]

Hello, how do i use eNum on a switch node, i have a widget with 2 buttons, if i click button 1 they will be in team A , if i click button 2, they will be in team B.
And i want different things to happend from the switch on the enum.

But the Switch node is always printing what i have selected in the input, i just want to have the 2 output, if Team A do this, if team B , do this

[frosty heron]

you can plug the input as variable

which you can set (e.g. changing the value on button click)

[cosmic dirge]

Should i convert the input to a variable, use the enum i have or create a new enum variable ? maybe it doesnt matter

[frosty heron]

does the same thing

[hollow bane]

i think i set everything correctly to true

but it doesnt wanna work 😄

[cosmic dirge]

okey, then in my widget, i dont know how to set the value

If this happens, i want Set to TEam A, for example

but enums doesnt work like that it seems, and that confuses me

[frosty heron]

You have to get the Team selection from where it is declared

[cosmic dirge]

Thats why i casted to aic enemybase first, i created it as a variable in there

[frosty heron]

casting is just a type check

it does nothing here

you don't need to cast, you can just get direct reference

[cosmic dirge]

okey, i tought i had to cast to get the variable instance

how can i find the variable ?

[frosty heron]

You pass it to your widget

I think you need to watch Blueprint communication video

[cosmic dirge]

Okey, thanks so far! 🙂

[frosty heron]

Team selection sounds like something that is attributed to a player

so player controller may be a decent place (assuming you don't want to use player states and other functions)

[cosmic dirge]

The creeps that i send, just belongs to a player, nothing is controlled, there is no player

There is no player character*

[frosty heron]

well you will need to pass that information to the creep

whom it belongs to

then the widget reads from the creep

[cosmic dirge]

My idea was, Press Button 1, spawn Actor A, set gameplay tag Actor A to Team_A, set Enum Team A

and for each creep with gameplay tag A, do this,

but i dont only want tag, because maybe it directs with other things that are already spawned

or smth

[frosty heron]

if you don't know how to pass variable to instances, then blueprint communication video by matthew should help

[gentle urchin]

Is there a Bug with setSphereRadius for collision volumes? Seems its setting it in diameter...

Sounds super strange

I set it to 5000, yet when i enter its radius, im at ~2500

[magic summit]

how do I put already rendered screen into render target? scene capture would need to rerender again what I have already rendered in main game camera so thats off the shelf

[frosty heron]

isn't RT just outputting what Scene capture is rendering?

[gentle urchin]

I may have missed checking the scale on it

That was it lol

[maiden wadi]

What are you trying to do exactly? What is the implementation for?

[unreal onyx]

When using Set Relative Transform to move an object, it's setting the scale of the object to default as well despite me editing it in the blueprint. Is there something I'm missing? Or do I just need to actually make a mesh and leave the scale at default for this to work?

[maiden wadi]

If you're just moving it, then set it's relative location, and not Location, Rotation, and Scale.

[unreal onyx]

Thanks, the tutorial I was watching used transform so I assumed that was the only way for all 3. I found the node you're talking about instead. Much appreciated! 😄

[manic vessel]

Im trying to make a stealth game and Im trying to get this system working where I use a scene capture to look at this shape and try to get the brightest and darkest pixel or an avarage but I'm hitting a wall in the BP

[frosty heron]

what do you hope to achieve with delay on tick?

its not gonna run it every 0.2 second you know

you can print string and check

[manic vessel]

thought that might be needed to update in in realtime

[frosty heron]

to update what?

[manic vessel]

the render target

[frosty heron]

I'm kinda lost

[manic vessel]

so am i

[frosty heron]

The issue that I see in your code is you add delay in tick

if you think it will run every 0.2 seconds, you are mistaken

[manic vessel]

dont worry about the tick, I just want to know how I could get the brightness value from a pixel. I tried and could no find any output I could use

[frosty heron]

what does the output return?

[manic vessel]

Looks like 27 is the maximum and 6 is the lowest I can get from this

[magic summit]

it doesnt really matter, I will find tons of uses for it, like shader stuff effects anything else

same as textures can be used for many things

[frosty heron]

it seems to me that you are just reading the blue channel value of pixel 0,0

https://forums.unrealengine.com/t/read-render-target-pixel-returns-highest-value/480012/2

[gentle urchin]

Hopefully your anim dont do any damage

[surreal peak]

In theory, if you have an AnimNotify driving Collision, you would store who you hit during the Anim and Reset the List at the end (or start, fwiw).
And then only deal damage if the target isn't already in that list.

You are probably dealing damage more than once cause the Collision overlaps different Components of the Target

[gentle urchin]

OnOverlap -> HitActors.AddUnique(Other Actor) -> Index > -1 -> ApplyDamage

On CollisionEnable you clear the HitActors Array

[balmy jackal]

Hey everyone, got a real specific problem I didn't know how to look up but feel like has a simple answer. Making an array out of static mesh components that are being spawned in a bp. In another BP I'm destroying said components but it doesn't delete the original static mesh components. I'm sure it's an easy fix but thank you for reading and any help is greatly appreciated

[visual ember]

doesn't delete how / from where?

[balmy jackal]

Sorry, literally just solved it by messing with it, was deleting it from another BP. Put the delete function within the og bp and had it called by the other bp and it works perfectly now

[odd crow]

I'm an absolute beginner and currently making a key and door system. I'd like to display a key image in the top corner of the screen when the player has picked up a key (by pressing E). I have a widget with the key image. Does anyone know how to make this?

[steel shadow]

in what blueprint do you register your key collection

You will need to do some kind of overlap check for that.

Then in your controller, you can do create widget > add to viewport

[gentle urchin]

Id let my main widget listen to my pawns "OnCollectedItem" ang create a WBP_Item_Entry that gets added to some Horizontal Box depending on type or something

[lyric basin]

Good day all. I have a question regarding adjusting a material blend weight (I think) based on distance to/from an object. I just don't know the correct nodes to use. I have the material applied to a post process volume and I can get it to turn on and off based on collision with a box. That part is easy. But the tricky part I have run into is getting the weight of the post process to change based on how close or far the player is from the object. The closer they are, the more pronounced the ppx will have on the screen. Any suggestions? I have tried adjusting the blend weight directly, but it only operates on a 0 - 1 scale and it appears to just be on and off from testing

the actual effect is static that gets stronger the closer you get to the object and it lessens when you move away from it. I have tried getting the distance between the two and using some math to generate a float between 0 and 1 and then plugging this into the blend weight to set it, but again, it appears to just toggle on and off.

[raven gyro]

is there a way to change the path of highresolution screen shot in blueprint?

[round elk]

hey im really confused

I added a piece to a character's hand, it caused the camera to be slightly tilted and move a bit to the side, even though it had to collision, so I undoed back to before I added it, and the tilt and movement stayed.Help?

[lyric basin]

you need to share some screenshots of the components section to give us a better idea of what happened

it was an actor reference

the blueprint for the actor has no collisions

but the camera still tilted

[lyric basin]

show where you added it?

[round elk]

thanks for your help btw

@lyric basin

[mellow pike]

so appantly the variable refs I make at the start are not being accessed ?
the first 2 screen shots is what I had and it works however this next 2 are modified to use the array of dynamic instant mats that are made on start (were as the first 2 use an array of the original)

my guess is the arry elements are not storing due to the soft ref so here is a thought

would I use all memory if i set current mat to null by the end ?

[cedar sparrow]

What's the best way to make something always face something else? I'm thinking of on tick having a ActorA's rotation always face the location of ActorB, but i dont know if there's a node to do that

[dry sleet]

There's nodes to get LookAt direction at least.

[cedar sparrow]

That worked. Thanks!

[round elk]

also the entire viewport is slightly rotated

its not just when I use PIE

i tried bugit 0 0 0 0 0

no help

[mellow pike]

just want to fact check this, is this info accurate ?

In Unreal Engine, local variables like your "current mat" within a Blueprint function do not require manual memory management as they would in lower-level programming languages. Unreal Engine's garbage collection system automatically handles memory management for objects, including dynamically created instances.

Here's how Unreal Engine manages memory for your local variable:

Understanding Unreal Engine's Memory Management
Garbage Collection:

Dynamic Material Instances: When you create a new dynamic material instance (UMaterialInstanceDynamic) in a Blueprint function, this instance is automatically managed by Unreal's garbage collection system. As long as there are no other references to this instance, it will be cleaned up by the garbage collector once the function scope ends, assuming the instance is not being stored in a class member or globally.
Local Variable Scope:

Function Scope: A local variable within a function is only valid for the duration of that function call. When the function finishes execution, the variable goes out of scope. If no other references are held to the dynamic material instance (current mat), it will be eligible for garbage collection.
Best Practices to Ensure Proper Memory Management
Avoid Unintentional References:

Ensure that you do not unintentionally store a reference to the dynamic material instance in a class variable or any other persistent storage that could prevent garbage collection.
Clear References:

If your function creates and uses a dynamic material instance but needs to ensure it is cleaned up immediately, you can manually clear any references to it by setting them to None if you have any way of holding references beyond the function scope.
Check Reference Handling:

In cases where you're passing references or storing them in other objects, make sure to properly manage and clear those references if they are no longer needed.
Example Blueprint Implementation
Here's a simplified example of how you might use and ensure cleanup for a dynamic material instance in Blueprint:

Create Dynamic Material Instance:

In your function graph, create a new Dynamic Material Instance and store it in a local variable.
Use Dynamic Material Instance:

Use this local variable to apply changes or settings as needed.
Function Ends:

When the function execution ends, the local variable current mat will go out of scope. If no other parts of your Blueprint are holding onto this reference, it will be marked for garbage collection.
No Additional Cleanup Needed:

As long as your Blueprint does not keep any persistent references to the dynamic material instance, you do not need to perform any additional cleanup manually.
By following these guidelines and understanding Unreal Engine's garbage collection system, you can rely on it to handle memory management for dynamically created objects like your dynamic material instance.

Is it more appropriate to set up a melee system in a State machine or using the Play Montage node? Most of the YT tutorials use anim montages but that doesn't seem right to me

Generally with montages

Hello where do ask help for on how to modify your actual game in Unreal Engine 5.4.3 ??

ah it uses blueprints

[spare sentinel]

how can i make the black ...translucent?

only show the white circles

[round elk]

um what

[nova scarab]

In ue5 the mod does not detected as in this video https://www.youtube.com/watch?v=SRVjv02cS7Y

[lunar sleet]

That’s probably cause it’s a UE4 mod

[nova scarab]

Yehhh but how to achieve the same in ue5

?

[lyric basin]

looks straight to me

[lyric basin]

ue4 and ue5, for all intents and purposes, are two completely different products. A lot of the code is different while a lot is the same. Just because something works in a previous version of Unreal does not mean it will work in newer versions. This is why you see every single asset available for UE will have the versions that are supported.

You gonna have to look to see if the dev implemented a workaround or if a community member has an unofficial fix/patch

[nova scarab]

Ok any idea on how to achieve same result in ue 5 ?

Any tut any idea?

[nova scarab]

Ok

[lyric basin]

emphasis on the you portion

I have no idea

there isn't a single on stop shop method to make things forward compatable

[steady night]

hey need tips on how to make a character transparent ?

[mental trellis]

Set their mesh to invisible?

[lyric basin]

ba-dum..tsst!

[maiden wadi]

The only thing that actually displays anything are materials. Like Daekesh said you can set the component or actor to invisible or hidden in game which entirely stops it from being rendered. Or you can alter it's material to be transparent.

[steady night]

aye im more after "transparancy" or rather 50% or something

[spark steppe]

like everything else

[dawn gazelle]

transparent = clear, effectively "invisible"
translucent = passage of light without a clear view of something beyond

[spark steppe]

you change the material to a translucent one

[steady night]

translucent then ok

ill testt

is it better to change a value (param) bia Bp or changing to anothermaterial thats already translucent

[spark steppe]

later

[dawn gazelle]

probably changing a parameter

[steady night]

xD

[spark steppe]

if you don't need translucent always, i would advise against rendering it with 100% opacity

it still costs more

[dawn gazelle]

I'm not a material expert so I'd say go with Ben on this one

[inland walrus]

Any ideas why this doesn't like getting reference?

[steady night]

ok so changin the material

replacingÄ

even if i do it every 2 seconds

back n forth

[spark steppe]

this is very much depending on the use case, etc.

and changing materials back and forth should cost pretty much nothing (i'm not 100% aware of the actual cost...)

[steady night]

okok

[dawn gazelle]

If you're getting an "Accessed None" error that means you haven't set the "Sky Reference" variable with a value.

[sharp void]

What value do you expect that property to have, and what causes it to have that?

[inland walrus]

I'm unsure

[dawn gazelle]

That may have set the type as BP_Day but that doesn't mean you've gotten a reference to the actual object that is spawned.

[inland walrus]

How would I do that?

[sharp void]

You set it to the value you want it to have, whenver you want it to have it. What do you want SkyReference to point to, and when?

Where does the value come from?

[dawn gazelle]

How are you spawning the BP_Sky blueprint? Are you placing it in the level? Are you using spawn actor from class?

[inland walrus]

Placing it in level

[dawn gazelle]

So how do you normally get a reference to an object you've placed in the level?

[inland walrus]

Ah so I need to get it from the level?

[sharp void]

I think you want a BeginPlay event that does BeginPlay -> Get Actor of Class (BP Sky) -> Set SkyReference

[dawn gazelle]

I'd also advise again using tick to check the boolean. Use an event dispatcher in your BP_Sky blueprint and bind to it on begin play of anything that needs to listen to the value, and read the current value on begin play as well.

[inland walrus]

Like this?

[sharp void]

yes. but you need to connect the return value from Get Actor to the Set

[inland walrus]

My bad, newbie moment from me😅 Thanks man this is working

[inland walrus]

Thanks, I will look into it

[wooden stratus]

Hi there,
I want to add a bit inertia/"a little push" to my character when he is walking above a certain speed and suddenly changes direction into the opposite direction. He should not turn immediatly but keep a bit momentum into the direction he was walking before changing direction.
I already have the needed checks in place but cant seem to add a little push to it.
I tried to change the "Ground friction" and "Braking friction factor" of the character movement component but the issue with those is that if I set them on "true", it will apply after the character has already changed direction because the character changes direction before the new friction values get applied.
Any ideas on how I would let the character keep momentum when changing direction?

Basically like in mario games where if you turn around approx. 180 degrees while walking fast, mario starts sliding a bit with momentum and walks into the other direction afterwards

[empty marten]

What you'd essentially need to do is store your previous velocity when you change directions so that you can then use a lerp node to blend between the previous velocity and the new movement direction. You then apply the result of the lerp back into your character movement velocity.

[dry socket]

hi, longtime lurker/first time cry for help.

I'm making a twin-stick shooter, but with the option to play local co-op where player 1 drives and player 2 shoots. To do this, I have the game detect if you select 1 or 2 players, and assign different pawns and IMCs for each player (player 2's pawn is invisible/immortal, and sends "shoot" events to player 1's pawn).

All of this works correctly in PIE. But in the shipping exe build, Player 2's joystick doesn't work.

I've seen some online posts about 4.27 and later UE failing to handle two controllers correctly, but few solutions (and none successful for me). Anyone run into this/know a solution or where to start looking?

[wooden stratus]

Does player 2 work with keyboard on the exe

[dry socket]

P2's IMC isn't set up with keyboard inputs. But that's a good idea for debugging I guess.

[wooden stratus]

This is a far reach now but I once did a small local coop project and the issue with blueprints was that if you wanted the game to be playable with multiple gamepads, you needed to write a custom assignment/mapping for this

Or else keyboard for one player and gamepad for the other was used

buuut this was on ue4, dont know how if it was changed up

[limber topaz]

Hello! I just starting using Unreal around 3 days ago and have been trying my hand at a 2.5D side scroller
I set up transitional animations for turning from left to right, but I can’t seem to match them with the way the character turns currently
Anybody have any ideas how I could fix this? Thanks

[dry socket]

for now I can at least check KB bindings. I think the IMC is getting assigned (the player's pause button works?), but for some reason the joystick is failing.

[wooden stratus]

Do you mean that you want to match the motion of the animation to the character turning around?

[limber topaz]

Like, instead of just snapping to the left and right poses, it plays a short transitional animation

Does that make more sense?

[wooden stratus]

Wouldnt that be just another state in your animation blueprint where if you turn into the opposite direction, your character enters that "transition to the other side" state which results in the animation playing and than you fire an animation notify event at the end of that transition animation to go back to your default pose

[limber topaz]

Could you put that in blueprints- 😭 I think I’m stupid

[empty marten]

You're not stupid. You're just learning something new. Don't be discouraged 🙂

We all started somewhere with UE 🙂

[limber topaz]

I tried the animation transition in the abp but since the sprites are also flipped it made it snap weirdly and flickered lol

Plus

When I first move it plays the turning animation as well which looks silly lol

I tried replacing the rotating for just making a new set of nodes that would play different sprites depending on if I pressed the a or d key it was very messy, if I held down both keys it would play the walk cycle in place and if I pressed a key before pressing the other the character would move in the idle anim

[wooden stratus]

You could perhaps create an animation montage of your animation

and play that montage when your character turns direction

[inland walrus]

What could I use instead of event tick?

[limber topaz]

Oooo I haven’t tried that yet

I’ll try tomorrow :3

Thank you!

[wooden stratus]

when the game starts, get the current state of the day and tell your AI to either "roam" or "night"
Create an event which only triggers if the day state has changed and then let your AI do the opposite thing

[wooden stratus]

Thanks, that was it!

Might it be because you're reference DLSS MOde Set and not your combo box which outputs the index number which your switch should be using as a switch on int instead of switch on UDLSSMode like in the video you linked?

hello

anyone got experience with 'LogRenderer: Warning: GPU-Scene Instance data overflow detected, reduce instance count to avoid rendering artifacts.'?
To me this looks like an error for too many instances of actors on the level which drag down the GPU power, causing low FPS?

[empty marten]

In order for this to work the process is, Event A) OnInventoryChanged has to happen so that Event B) InvetoryChangedHandler executes which then goes to Event C) UpdateGrid. If Event A does not happen, event B and C don't get executed.

[empty marten]

Try stepping through your code using break points to see what is and isn't being executed as something might be holding it up.

[empty marten]

Is this in a widget?

[agile moss]

Yes

Although I might have found a node online that better suits my needs

[empty marten]

And which one would that be?

[agile moss]

"Remove from parent"

Im gonna test it out

I want to create a new widget each time and the old one is deleted

[empty marten]

Ah fair

Hey everyone, im facing a bit of a challenge here i guess.
Im working on simulating a cable by stacking capsules as a skeletal mesh. The setup works perfectly in the physics simulator, but I'm encountering an issue when moving the start and end points of the cable. Once the cable reaches its limit, it begins to jitter, unlike the cable component, where I can smoothly control both the start and end points.

the cable should stop when it reaches its limit ( that what I want to do)

[true ocean]

Oh yeah sorry that's what i was trying to indicate with the purple notes, it does get called, but the handler doesn't for some reason

[sand warren]

Hello quick question, i follow a video about stopping attack moves when weapon is not equipped but i'm not sure the reason the code don't work (i can't attack with and without weapon) ?

[empty marten]

Might it be because you have it executed from Pre-Construct so its not getting a chance to call yet?

[empty marten]

Your active weapon has nothing to check against.

[upper stump]

is there a node that would allow me to pick the component i want to add?

Working on a weapon system and i'm looking for a way to customize this , or maybe is there a better way of doing it

nvm, just realized its add component by class..

[empty marten]

....

[sand warren]

hey @empty marten, the video i watched stated that by doing this, you are doing if active weapon == none then you can't attack

[upper stump]

sorry, was sure it has to be add skeletal component

[empty marten]

Oh sorry. I misread.

[empty marten]

Do you have a link to the video?

[sand warren]

yea here: https://www.youtube.com/watch?v=dpt3BC8kkmQ&list=PLiSlOaRBfgkcPAhYpGps16PT_9f28amXi&index=34

[empty marten]

Time stamp?

[sand warren]

starts at 7:21

[empty marten]

Also I assume you've checked all your variables are getting the right value at the right place as I'm noticing a few booleans that might get mixed up easilly.

[sand warren]

i've made sure that can attack? is set to ON

[empty marten]

So something you could do is print out the value of that boolean and see what value its getting (true or false)

So just do something like this quick. That way you can see if its staying as 1 value or constantly switching between 2 values.

[sand warren]

ill try now

[true ocean]

I tried moving the binding to construct in case it was some kind of too early binding and that didn't help, and the event doesn't get called until a player clicks a button, so there should be plenty of time for it to get setup before OnInventoryChanged is ever called

[sand warren]

when i do it with the can attack varible, i get true when i tick the variable ON and false when i tick it OFF

[empty marten]

Sorry I think you've mis-understood what I was triyng to explain. I mean like this. Get the event tick, get the value coming out of the == and put that into the print string to see what you get.

[sand warren]

oh ok one second

[sand warren]

i did it and i end up getting False

[empty marten]

So you know CanAttack? is getting set to false but is it consistant to that? Try setting up the Event Tick like this to see if CanAttack? stays at false.

[sand warren]

it does stay at false

[empty marten]

OK so we know the variable is fine. Where is the code where you equip a weapon?

And then set CanAttack? when a weapon is equipped.

here is the blueprint for item pickup

OK but where are you setting CanAttack? after a weapon is equipped?

At the moment CanAttack? is always false so you won't be able to attack.

i only use can attack in my attackingsystem

I was just reading through the comments section of the video and someone has reported an issue with setting teh CanAttack? with the == on BeginPlay.

This is what they wrote.
setting can attack with the == on begin play doesnt work. in the bpc equipment system your setting can attack to true everytime you open and close equipment panel. so basically you open inventory with or without picking anything up your enabling can attack and you play sword attack animation. so delete can attack from the false branch. in bpc attack system on begin play set has bow and can attack variables to false. on q key set has bow and can attack to false, then drag from can attack and get the unequip bow in hands plug characterbp into it. drag from character and get equipped weapon, from that drag and set visibility to false and make sure its hooked into the unequip bow. so the q key should have 5 nodes {q key, has bow, can attack, unequip bow in hands, set visibility. now in wb_equipment panel drag from character cast and get bpc attack system, from that set has bow connect it into the end of equip melee item leave it false, from has bow drag from bpc attack system and set can attack and check it true. right click get the 1 keyboard key and hook it into the beginning of can attack you just hooked to false has bow. from that can attack call unequip bow in hands and drag from character cast to the target of unequip bow. from unequip bow drag from bpc attack system again and set can attack to true and set has bow to false. so from equip melee item you should have 6 nodes. from the ranged weapons-equip bow set can attack to false and set has bow to true. search for the 2 keyboard key hook it into the set has bow and then from the set has bow call the equip bow in hands and hook the character into the target. so now when you select from your inventory your setting your weapons and when you close you can now use your 1 and 2 keys as hot keys to swap from melee to bow and vice versa without having to open your inventory and reselecting a weapon. and when you press Q everything cancels and your back to regular walking. then just press the 1 key and bam, you automatically have your sword, press 2 and it switches to the bowstuff. of course if you plan on adding a pick axe or axe or gun you will have to add more stuff to that code. but i just showed you how to cycle 2 weapons! you will also notice that the 1 and 2 keys will not work until youve selected from your inventory. so its almost like playing a real game but still a few bugs. the main bug ive found is, well let me back up here. items in games that have inventory or in this case an equipment panel acting as your inventory {backpack} are only suppose to be activated when you open your inventory and select an item. my method does this flawlessly. you cant equip the bow or sword without setting it in your inventory. the inventory system recognizes this perfectly. the only thing i cant figure out is when you pick up the sword and the bow, then open your inv and select just the sword it works, but, you can also press 2 and it equips the bow without it ever being set in the slot. but it also doesnt activate until you pick it up and set one or the other. thats the road block ive hit. it still functions as it should, but its more like an auto set has been created once you pick up an item. so it isnt that bad or gamebreaking its just a bug ive found.

TL;DR

[sand warren]

ill try this now

[empty marten]

After this point I won't be able to advise much more without going through his entire video and attempt to replicate his code myself.

[sand warren]

i understand because i only followed his attack system and not the rest of his stuff

[empty marten]

Then there's a chance you're missing something else he implimented elsewhere.
