blueprint

[burnt nest]

Or you could just use your player character's forward axis for starters.

[sick sapphire]

this is a bit of blueprint that controls how much my character aim up/down animation
right now, the aim up/down animation
when the server does it, it does not show in the clients
when a client does it, it shows on the server and that specific client but other clients do not see it

i think its not copying something from the server to the clients
AimPitch is just a variable inside the event graph of the animblueprint it is not changed anywhere else

[native creek]

Is the AimPitch set to replicate? And after it replicates do you set it on client?

[zenith rose]

@burnt nest ok thank you ill try it

[sick sapphire]

it's not
how do i set it on client?

[native creek]

I'm not sure how AimPitch is applied in your code to actual camera pitch. So maybe just setting the variable to replicate will be enough. Go to variable settings where you can set the type, name etc. and set it as Replicated.

The character itself has to be set to Replicate as well of course.

[sick sapphire]

it uses these to get actor and control rotation and aim pitch is set based on that
replicating the aimpitch didnt work

this is how it is applied to animation its an aim offset

[native creek]

One issue could be that the code that sets the AimPitch is running on server and all clients. So even if the variable replicates correctly you immediately overwrite it on client side.

[sick sapphire]

fair enough
so i think i will make a custom event that is "run on server" and try that wait a moment

[native creek]

Try to debug what the AimPitch value is on client when you change it on server. Does it match? Is it completely different.

[sick sapphire]

ok i will do that

[sick sapphire]

ok so the server will get all the aim pitches of the clients and server, thus can see the anims of all
the clients will only get their own aim pitch, thus can only see their own anim

[woven kelp]

How do you conditionally consume input? I have two things listening to mouse wheel, but only one is active at a time. But the event node doesn't seem to support conditionally consuming it

Do I have to spawn/despawn an actor just to turn the consumption on/off?

[native creek]

I'm not sure what you mean. Replication only goes in one direction Server to Client. So say you update AimPitch value on server and you want it on a client. If it's set to replicate, you will get the new value there. Then you do what you want with it.

[sick sapphire]

ive just put a print string right after the node that sets aim pitch
there is 1 server and 2 client here
client 1 and server are looking in different pitch
so what i think is happening here is
server receives all AimPitch values
client 1 and client 2 only have their own AimPitch values

aim pitch is also replicated here

[native creek]

So client overwrites the replicated value then. If it sets AimPitch locally. If you only want the servers value, then you should prevent client from setting its own AimPitch.

[sick sapphire]

i see
how can I prevent that from happening?
is there a check to see if player is server or client
putting the 'set AimPitch' node in a 'run on server' custom event didnt seem to work

[native creek]

There are multiple ways to do this, but you could just use HasAuthority node in this case. Only server will have authority over the characters if it spawned them originally.

[lime karma]

Okay I feel like I'm really close to what I'm trying to do and I just don't quite know the last few steps I think, unless I'm just way off target. I'm making a basic FPS just to sorta explore all the systems and such and get hands-on with the engine and this BP system. I'm working on a system to swap between the various weapons the player can have. I've got it so that I have a master parent blueprint for weapons in general, and then children of that for each type of weapon individually (no real code in them yet just sorta structuring everything for now). Then I'm storing those classes in an array and setting a child actor attached to my player to whatever class I want in that array on the fly. So far all that seems to do what I want with at least visually swapping out the guns and everything.

My question though is uh, how do I then access the actual functions within whatever my currently loaded class is? Like if I wanna take my Fire Input and then pass that on to whatever arbitrary weapon class is currently stored within the child actor, so that I can then put the logic on the guns themselves to make the projectiles come out after receiving the input. It'd also be nice if I could access other variables and such for manipulating the ammo counts but one step at a time. Is there some relatively straightforwards way that I can just like, take the input, and other potential variables, check what class is currently the active weapon, and then just pass it along? Or should I maybe just call for input within the gun classes themselves? Or am I just way off target here.

[twilit heath]

your character can be prevented from firing by effects weapon doesn't need to know about

like being dead

[native creek]

Your approach sounds good. With the parent/child weapon classes. So those classes will have some kind of variables, like for example magazine size, which might be different for each weapon. Or amount of damage. You can make those variables public if you want. Then you can grab them from character class.

[twilit heath]

so your input should go through the character there, and it should have a CanFire() function that it checks before forwarding the fire call to the weapon itself

you should have an active weapon reference at all times

so simple version of characters CanFire becomes

[sick sapphire]

ok now i added this to the nodes
now only the server has the animation (it has both clients and server) because the clients are not setting the aim pitch
i think i need a way for the clients to get the aim pitch values from the server

[twilit heath]

bool AMyCharacter::CanFire() const
{
  return ActiveWeapon && !IsIncapacitated():
}
void AMyCharacter::Fire()
{
  if (CanFire())
  {
    ActiveWeapon->Fire();
  }
}

then your weapon does its own checks, not jammed, destroyed, has amo in mag... etc

before it actually goes to shoot

[lime karma]

heh at least I'm not totally crazy. Well first things first how would I actually call an event within one of those weapon child bps from my character BP? Like if I wanna accept input on my player, do some logic, then pass it on to whatever weapon he's holding, do some more logic, and then bullet come out

I'm lost on the 'pass it on' step

[restive dagger]

Is this gonna work? https://gyazo.com/41cf82ff93461ff0a7dca54e5461510e

What I'm wondering is, if the first boolean is false will it execute the second branch?

[native creek]

Replication should already do that for you. Now that client doesn't overwrite it, check if the Client value doesn't update when it updates on Server.

[native creek]

Like @twilit heath said. You keep an active weapon reference on your character. So the "pass it on" step is as simple as WeaponReference->DoSomething().

[tiny meteor]

anyone know why two physics meshes wont trigger overlap events one each other?

[sick sapphire]

no its just not setting it at all
the server gets both client and server AimPitch, so the animations show on the server
but AimPitch is not being set on the client at all (0.0 is default value)

[lime karma]

what would be the BP equivalent of this? I'm currently learning that system and everything is blueprints so far

[maiden wadi]

@sick sapphireDon't use GetControlRotation. That is for local use only. When using replicated rotations meant to be used for the direction that the pawn's owning controller is looking in, use GetBaseAimRotation.

It's a first person function to get the control rotation via the character's Z orientation, and a replicated pitch value.

@lime karmaIn blueprint, one of those is a function, the other is an event. The top one is a function because it returns a value. Make a function that has no inputs and returns a bool and name it CanFire and mark it as pure. The other one should probably go in the graph as an event which has a branch that checks CanFire, and calls fire on the weapon if true.

[lime karma]

I understand the logic, I don't know what the blueprint syntax is to do it. Like what nodes do I need to call the fire event on the weapon from the player

like I can't seem to find any good examples or anything of this sort of thing that are easily accessible, so i'm totally lost on how to actually implement it

[worldly mist]

anyone know why the rocket isn't mainting the physics linear velocity that it was set at? This was all working in UE4, but when I ported it into UE5 it just decided to stop working

[maiden wadi]

@lime karmaWith what he wrote, it would directly translate to this in blueprint.

Both of those in the character.

And then this in the weapon.

[lime karma]

okay, the part where I'm getting stuck, is the Fire Weapon node

I can't get that node

[haughty crypt]

hey guys, is it possible to add new names to an enum table through construction scripts?

[maiden wadi]

Your ActiveWeapon's class would need it, like in my last screenshot. There's two classes. The top two pictures are the character. The third is a weapon class.

[lime karma]

yeah I have a parent BP for my weapons that looks like this, but this is just the parent, I have a child of this for each weapon

[maiden wadi]

If that's your weapon, you'd replace my "FireWeapon" with your "Fire"

[lime karma]

yeah yeah of course, but the weapon is a child of this, I think I might not have the children set up right or something

[maiden wadi]

Should still be able to call the Fire function if it's a child. Children inherit their parent functions.

[lime karma]

that's what I was thinking, but something is clearly going wrong

[sick sapphire]

thanks that solved it

[maiden wadi]

Open the child blueprint, look up at the top right. Does it have the parent's correct name there?

[lime karma]

yeah it's up there, though when I try to add the Fire Function to it, it looks like this now

which is clearly wrong I imagine

[maiden wadi]

Ah, sec. There's two ways to do that.

Yeah, the blue is a call not a declaration.

[lime karma]

yeah it looks like the event graph, if I'm reading it right, isn't being carried over for some reason

[haughty crypt]

how would one list how many members are in a struct, or better yet, putting each member in a struct into an array

[maiden wadi]

If you right click in the graph, the top is to override the event in the child. Sorry for the small screenshot. Work project. 😄

[lime karma]

no worries

[maiden wadi]

You can also go to the left side and click here.

The override button. Anything marked as Gunthing is inherrited from the parent class. So the FireWeapon there. Would add the same thing as the highlighted screenshot above.

It just overrides the parent's functions.

If this is in the parent.

That will be added to the child if you select one of those.

[lime karma]

ah so like this

[maiden wadi]

Yep. And if you still want to retain functionality from the parent. Also right click the red event and "Add Call To Parent Function" or whatever it is.

[lime karma]

right, I don't think I'll need that yet but I'll keep it in mind

[maiden wadi]

You cannot really do that in Blueprint I don't believe. Not even so sure you normally do that in coding.

[haughty crypt]

I'm really just looking to add each element's name into an array to create an enum of each one

so when I add an element to said struct, it adds an element to an enum, that could be selected in a blueprint

[maiden wadi]

That's an unorthodox way of handling things. I would just do it by hand if you add an element to the struct. I doubt you'll find an easy way to accomplish that.

[lime karma]

okay so moving back a step to actually calling those functions within the child blueprints

I still can't figure out how to pull up the relevant node

[maiden wadi]

From the character?

[lime karma]

yeah

[maiden wadi]

Do you have a blue pointer type variable of the weapon's parent class type?

[restive dagger]

can anyone tell me what is causing infinite loop here ? v

https://gyazo.com/d5de79330b0e30dffd7e68d9ad244f66

[lime karma]

I'm going to go out on a limb and say nooo? Even though I thought I did

[restive dagger]

https://gyazo.com/52bb33cd8019cd071effeeedd5e18055

[maiden wadi]

@restive dagger Nothing. What does AddSkyObstacle do?

You have an overlap event. That spawns an actor, that causes the overlap event, that spawns an actor, that causes an overlap event that spawns an actor that...

[restive dagger]

ohhhh

[haughty crypt]

so just to add on to the last question as well, is there any way of adding an element to an enum in a construction script?

[maiden wadi]

Not likely. They're two very separate things. Construction Scripts run when the class is instantiated into the game. Enums need to be created long before that.

[restive dagger]

Do u know how to fix that? I highly depend on the overlap event to spawn the actor

On actor hit?

or thats the same hmm

[maiden wadi]

Actually on second glance I'm technically incorrect. What are these objects you're spawning?

Are these Sky objects the same thing with the Overlap event?

[restive dagger]

I'm spawning the sky object that has the spheres^

which cause the overlap event

[young cradle]

guys how do i make it so my nodes arent disabled?

[restive dagger]

https://gyazo.com/ac407adc4dead2f8fb7cefc924d3520b

[maiden wadi]

Hmm. For some reason they seem to believe they're already overlapping the character at spawn.

[restive dagger]

They are not disabled, you can plug them any time

[young cradle]

how

[restive dagger]

You are somewhat right, its an infinity loop because its overlapping over and over again, when I spawn the sky obstacle it may overlap with the character again?

[young cradle]

im trying to spawn nodes i forgot the control what is the button

[restive dagger]

right click on the mouse and search for the node you want

[maiden wadi]

@lime karma https://cdn.discordapp.com/attachments/221798862938046464/853244422544556062/unknown.png
In this one, I have the ActiveWeapon variable. Which is the same type as the parent gun class that has the first FireWeapon. It's just a pointer variable. It'll be empty by default so invalid. Not sure how brushed up you are on pointers or blueprint references.

[young cradle]

it isnt doing anything

im right clicking

nothing is happening

[restive dagger]

@young cradle you must right click on the blueprint empty space

[lime karma]

I am very unbrushed on pointers and blueprint references

[young cradle]

i am

i think

im clicking on a blank area

with right click

it aint working

[restive dagger]

hmm

https://gyazo.com/f71e5e6c0a7fb2fecec081d5cda412f4 try like this

[olive sedge]

Is it possible to switch on arbitrary things like Material Interface Object Reference?

Don't want to create a whole tree of branches

[maiden wadi]

@lime karma Haha. In short. A pointer is just a small variable type that points to a specific object. Or more appropriately, that object's memory location. Unreal marks these as nullptr by default, and uses that to check if they're valid or not. Which is what the IsValid node is for. If it isn't pointing to a weapon it'll be nullptr and invalid. You'll no doubt run into the error warnings soon. To use these, you have to populate them from a valid reference. You most often get these from the place the object is instantiated.

[young cradle]

it didnt bring up the menu thing

and once i right click again

it disapears

[maiden wadi]

@lime karmaSo for instance. If we spawn a weapon on beginplay in that character like this and set the ActiveWeapon.

[restive dagger]

@maiden wadi Am I teaching him wrong? whats wrong with his blueprint

[maiden wadi]

Then after Beginplay, that reference will be valid until the weapon is destroyed, or that variable is Set again.

@young cradleDrag and left go. The menu should show up.

[young cradle]

no menu

[maiden wadi]

Try to right click to bring it up. Add a PrintString node and connect it.

[young cradle]

nope rightclick made it dissapear

[maiden wadi]

The menu, not the line.

[lime karma]

this is how I'm starting things out with instantiating my child actor from my array of weapons. Equipped Weapon is the child actor, so do I just set another actor variable equal to that?

[maiden wadi]

@young cradle

[young cradle]

but right clicking only makes me drag and move

around the blueprint map

[maiden wadi]

Click, don't hold.

What Unreal Engine version are you using?

[young cradle]

how do i check

[maiden wadi]

Help->About Unreal Editor

Should display a popup with a Version on it. Like Version: 4.25.4

[young cradle]

clicking on it does nothing

is it just not responding or wat

4.13.2 is my version

[maiden wadi]

Modding editor, or?

@lime karma Ah. Child Actor Component. Not a fan of them, but that's a different discussion. To get the same pointer, you have to take the child actor component's pointer, and getchildactor.

[restive dagger]

OH FINALLY I think I found the problem

[lime karma]

this?

[restive dagger]

https://gyazo.com/97e2cd9b6b41eee36e80f61e7d22bc5e this is full of branches, and it gets called even before the branches are set which in return will cause them all to spawn in one location https://gyazo.com/79f55ea85ee6c045562582160ea37818

[maiden wadi]

@lime karma Yep. But I would change Current Weapon to the parent gun type. Which will require you to cast ChildActor to that type too to set it.

[restive dagger]

So how do I fix this?

https://gyazo.com/9795e2e512dcae80c69f538c6bb59d43 heres how I set up the system

I want (in the sky sphere) when u reach a certain point another sky sphere appears either up/down/right

just like an endless runner

but the system is not working properly

[lime karma]

so how do I get the parent gun type to set it to that then?

[maiden wadi]

If your childactor in the component is of any type of the parent or it's inheriting classes, you just cast to the parent type.

[young cradle]

guys does anyone know how to place nodes in 4.13.2

right click is drag and move for me

[lime karma]

ah so now is when casting comes into play

[maiden wadi]

You're going to hear a lot of really stupid explanations about casting. To save you some trouble and severe confusion there, casting simply tries to change a pointer type. It does not modify the object in any way, and more importantly it does not "get" anything.

[lime karma]

yeah that's what was really messing me up on my first attempt at this

so now I think I'm on the same page

[maiden wadi]

All casting does is literally.. You have an object that is in a pointer that is a parent type. In this case, you have a childclass of your gun. Your gun likely inherits from Actor. Actor inherits from Object. So your inheritance chain is Object->Actor->GunParent->GunChild. This means that a Gunchild can be stored in any pointer type of any of those four.

[lime karma]

so we're using the cast to go up a level from the child to the parent

[maiden wadi]

In this case, you have an actor pointer. It's still a GunChild, but it's stored in an Actor pointer. So you change the pointer type to GunParent to get access to that Fire function.

[twilit heath]

best not use child actors though, especially if you're going to be swapping weapons or doing any networking in the future

[maiden wadi]

Yeah. Child Actor Components were a failed experiment at trying to make the designer side of things more friendly. They're terrible in their handling though.

[twilit heath]

dropping them would also be... interesting

[maiden wadi]

One of the many things that should be deprecated or overhauled.

[lime karma]

I was trying to use it as I thought it would help generalize these function calls, but it's becoming increasingly clear that it's just a middleman not really doing anything I think

[maiden wadi]

Realistically, you'll get the same functionality out of just spawning it on Beginplay.

[twilit heath]

you only need a pointer to active weapon

[maiden wadi]

With less problems.

[twilit heath]

nothing else

[lime karma]

I was about to ask if it would be better to just spawn the weapon

[twilit heath]

and attach it to a socket on skeletin, yes

[maiden wadi]

You're not into multiplayer stuff yet, so abuse the shit out of Beginplay. 😄

[lime karma]

lol

[young cradle]

i think unreal engine is broken for me i can place nodes

[maiden wadi]

@young cradleAre you using a modding version of the engine for some game?

[young cradle]

how do i chek

[maiden wadi]

Ask yourself if you're trying to mod an existing game?

[young cradle]

no

im not

im planning on making a game myself

[maiden wadi]

I would seriously consider updating. You're working on a nearly four year old engine version.

Try 4.26.2 or 4.25.4

[young cradle]

how

[maiden wadi]

How did you download the engine in the first place?

[young cradle]

https://www.unrealengine.com/en-US/download

[rough bear]

can someone tell me why this wont work

[gusty shuttle]

OKay, my build is failing, any clue how to fix malformed tags?

[maiden wadi]

@young cradle Check out downloading the launcher, you should have this screen in Library.

[severe turret]

@rough bear what is happening? Perhaps it's just jittering at the start of the timeline as you are using it OnPressed which will repeat when held?

[young cradle]

im downloading it rn

lets hope it works

[rough bear]

i am making an endless running game https://www.youtube.com/watch?v=KdkDqk_YBS4&t=181s

followed this video ^^

[lime karma]

I think my brain wants to do a nap so I might have to return to this later

I think something is still going wrong because after casting it's still not letting me pull up the function

[restive dagger]

Guys can anyone tell me what to do https://gyazo.com/f6528d0a3c09e552425db0b14074912a

[lime karma]

I'll try take out the child actor and return to this later

[restive dagger]

this function is not returning the attach point which makes sense

are there any other approaches to get what I want? other than this function

[maiden wadi]

@lime karmaMake sure your ActiveWeapon variable pointer is of the correct type. You likely have the VariableType here set as Actor, or Object.

[rough bear]

pls someone help?

[maiden wadi]

@rough bearEndless Runner code?

[rough bear]

can i dm you with the problem?

[maiden wadi]

Not really a PM person. But I can say that you're over complicating this. You should really just be doing this on tick with some simple math instead of trying to keep a timeline running correctly.

[lime karma]

oh wait that's how that works?

[maiden wadi]

Yep. Your pointer type will be what gives you access to the correct functions.

[rough bear]

am following this video

[lime karma]

ooooooooh

yup now it shows up

[rough bear]

can someone help?

[lime karma]

thanks so much for everything, I think I got it to the point I wanted

though if I'm not gonna use child actors anymore, for the weapon switching should I just despawn the old weapon and spawn in a new one?

[maiden wadi]

Unfortunately that's actually a rather design oriented question that isn't simple to answer. It really depends on what kind of handling you want. Are we talking basic FPS with weapon swapping? Possibly. Though it can be cheaper on runtime resources to just spawn them all and allow a "dormant" mode which hides them elsewhere. But that's premature optimization stuff.

[lime karma]

I was wondering if that was an option as well, just like hide inactive guns behind the player or something

[green bluff]

Oh sorry man, so many notifications I didn't see your message!
Delete vertices/polygons in LOD0 specifically, for example when you touch the model, you delete its vertices.
I wonder if its possible in realtime

[maiden wadi]

You may also want a system that shows secondary weapons on the character when they're not equipped. They'd still need to exist.

[lime karma]

well it's first person so you can't really see yourself much

[maiden wadi]

Which is true. Was considering more third person or multiplayer.

[lime karma]

mhm for now my scope is a bit smaller lol

[maiden wadi]

But yeah. There are other factors too. UI is a consideration.

If you have a system where character stats may affect the weapon's stats.. Like.. Maybe some mix of strength and agility or some perks like SteadyAim affect weapon aim or recoil. You would need to consider if it's easier to leave the weapon spawned and simply pull that directly, or have a system in place to do those calculations same as the weapon does.

Most times, you're going to find it a lot easier to just have the weapon spawned and use the same calls the weapon does for it's own use.

Like.. Say you have three weapons. SniperRifle, AssaultRifle, and Handgun. If you have the AssaultRifle out, but still want to tab and see the stats of all weapons at a glance, you'd need those spawned, or that other system there to get those stats based on the character or player who plans to equip them.

[lime karma]

yeah I remember seeing an issue someone else was running into during my initial research where they were despawning the guns when not in use but that caused them to loose their ammo counts

since they'd be reinitialized with full clips

well at least now that I can make functional guns, I can finally start to experiment with systems like that and see what I can come up with

[maiden wadi]

Realistically, spawning is expensive. Keeping something spawned usually isn't if you correctly disable it.

[lime karma]

I may or may not return shortly to learn what "correctly disabling it" means

[maiden wadi]

Having stuff spawned is very cheap. It's a miniscule amount of RAM. Spawning requires CPU time.

[lime karma]

and you can always download more ram

[maiden wadi]

Haha. Mostly it's just disabling tick and removing collisions.

Few other things. But those will cover a lot.

Vsibility and such.

[lime karma]

I'll look into it in a bit

I believe you're looking for child blueprints not actors

I am far from an expert but from what little I currently understand, you can make a single master blueprint for the elements that are shared between your characters, such as basic movement or whatever, and then create child blueprints for each character that will inherit all of that and house the individual logic for each hero such as unique abilities and such

[loud cipher]

Hey all i have a third person template project and i have set up a system with a camera in the corner of the world, when the player overlaps a box it switches from tp camera to the world camera

however when im in that world camera seperated from player camera

the controls of the character are inverted

how can i counter act the inverted controls?

[gentle urchin]

Possibly using cameramanagers forward vector as reference

[rose girder]

how do i increase the thickness or radius of my trace sphere?

it's barely visible

i increased the radius but nothing happened

[smoky bluff]

i think i discovered one of the mysterious macro issues with nativization, custom macros with delays in functions don't nativize properly, to be fair I should probably test this further before making that claim, but still weird. or probably already widely known..

[icy dragon]

It is a well known fact that BP Nativization is so wonky, it's FUBAR and outright removed in UE5.

[smoky bluff]

no kiddinggggg. Well that's a little bit of a bummer, I always believed in its potential hahaha

[tiny plinth]

does anyone know if timelines can be threaded? Like if I have a method that's called 5 times at once that uses a timeline, will that make 5 different instances of the timeline running or will it just try and all use the same one?

[raven pilot]

is it possible to check how many blueprints you have, like how to can see how many line of code you have

[celest pilot]

@indigo bough oh wow I just noticed the ping from 16/04 😅 were you able to make something similar now? Talking about this : #blueprint message

[indigo bough]

Haha no problem. Not yet! Will probably try this in future though

[celest pilot]

Awesome, it's a bit out of my league but I'm sharing it with some people I know who also have interest in it

[trim matrix]

Is there a way to get the player ping through blueprint?

[wind sequoia]

player state

they have a variable

[trim matrix]

ty

[wind sequoia]

just make sure to multiply it by 4

@trim matrix

[smoky bluff]

if you start a timeline it just goes, so the resulting data will be the same for anything accessing it. That's what the "play from start", "play (resume)", "play backwards" and "play backwards from end" or whatever it is, is for. only time 5 timelines would be running is if you made 5 timelines in your bp

[clear osprey]

Why I have these yellow dots in the blend space?

[proud sable]

I have 3 characters using the same blueprint, they all have different variables set. When I start the game they all begin with the default values but if I do an action that updates them they change to the values I set. How would I make sure they begin at the proper values? Sorry if this is explained poorly, I don't really know UE terminology too well 😅

As an example my default "mana" value is 100, one of my characters' mana is set to 500. If he uses an ability that costs <100 his max mana jumps to 500. Can I get it to start on 500 instead?

Edit: Realized I had to go back and set the "current" values to match the "max" first

[drowsy vigil]

So I've been scratching my head on how to make a procedural first person walk animation for a weapon, I know i could just use anim blueprints but I wanted to try this instead, I'm not all that knowledgeable of UE, started using it about 2 weeks ago, but I assume it would use lerps and get/setting relative locations of the viewmodel, etc. Any help or advice would be appreciated :)

[high ocean]

Can anyone please tell me what the math equasion(s) are behind "Map Range Unclamped Node"? I just need the math behind it 😐 I need to make an excell formula out of it 😅

[gentle urchin]

Basically you find the % in range of the input value and multiply it by output range + output min

[high ocean]

Ok...lemme try that & see if I get the same result as the node prints 🙂

so... "find the % in range". I don't get that part - sry

[gentle urchin]

Input range 0-100
Input = 50
50/(100-0) = 0.5

In / (InMax - InMin)

Remapping it then means applying the value to the output range

OutMin = 100
Outmax = 200

In% * (outmax-outmin) + outmin

(0.5 * 100) + 100 = 150

[high ocean]

@gentle urchin returns another value... One case I have is this:
min: 1
max: 10
outMin: 4
outMax: 10
Value: 3.85

If I got this right, in this particular case it would be:
(3.85/4)=0.42
0.42*6=2.56
2.56+4=6.56

The unreal remap node prints 5.9

[gentle urchin]

Closez had a feeling i was missing one bit

Gotta remove the input min range :)

(In - Inmin / (Inmax-Inmin) , possibly + in min

On the phone so cant double check it

[high ocean]

Besides, which one of these is it? inresult*(outmax-outmin) + outmin; or (inresult**outmax) + outmin the text reads one, the example another 😅

[gentle urchin]

(Inresult*(outmax-outmin))+outmin

[high ocean]

will try again 😄

Heh... it's not, and I can't figure out where those weird differences are... In my fiddling around with the calculator trying to "rediscover" the equation, I came clos(er) to your result - which makes me wonder how ue does it under the hood...

[gentle urchin]

Not sure i see the problem

I get 5.9000002 aswell.

[high ocean]

😮

[gentle urchin]

Ignore language lol

[high ocean]

Oooooohhhhh THERE you remove the min 🤦‍♂️ sry, I'm retarded 😄

thought you meant to remove it at the end so i just ended up ignorin that last bit 😅

[gentle urchin]

Ah 😅

[high ocean]

Ok... It's weird how the math itself kind of even makes sense now 🙂 miles of thanks man, you saved me! 🥳

[gentle urchin]

Glad it gave you clarity,

Even when I failed to describe it properly

Not sure if my approximation to it even describes it, but it made sense in my head

[high ocean]

Heh, yea, that part where you have to remove the min is odd and doesn't make much sense, but, it is what it is! thank you! 😄

[gentle urchin]

But it does ! You need to normalize the input so that you can directly divide on the input range

Subtracting min is normalizing it, making its value become a direct relative value to the inout range !

I feel like im rowing this boat in the qrong direction but oh well

[lime karma]

I just wanna say that I managed to get my weapon system completely working as I wanted it to now and I even removed the child actor nonsense

[high ocean]

For all the math they've pumped into me in high-school (come from ex-soviet country, we did a fekload of math) we never understood how to actually use it, and now I'm rediscovering terms and concepts I had to know superficially to pass the national exam 😐 Sad man...smh. 5hrs of math/week, learning polinominals, log equations and diff equations, integrals and whatnot, only to be unable to do simple arithmetic...

[gentle urchin]

Well tbh schools never did a good job explaining why we had to do certain stuff during alot of the formulas... it was just dumping the formula onto people, forcing you to memorize shit (which is harder when you dont understand the why)

[high ocean]

exactly! but then again, if you go out of math/programming/sciences where you learn/have to actually use it, and go into humanities like me, you forget all formulas because they never made any sense/had no use to stay in memory... But it would be so much fun to actually teach math's usefulness.

and those endless trigonometry tables with apparently random numbers with a radical and pi thrown in every now and then we just memorized lol...🤦‍♂️ 😂

Aaaanyway, thanks for the help, don't wanna clog the channel with my rumbling. 🙂

[gentle urchin]

No prob !

[open crypt]

Ugh, why is my camera actor not possessing the pawn correctly

I'm trying to switch to a camera actor so I can record some camera movement but it's not working even though references are good

[smoky bluff]

try set camera view with blend node maybe?

[open crypt]

before I was doing this and it worked fine

I'm not trying to look at a target, I'm trying to switch to a different camera

this is super basic stuff, what am I forgetting

[spare wyvern]

I tried retargeting the anim bp and it turned all the animations to T_Poses. I don't think this ever happened to me, and I don't think i did anything different. Is this some kind of bug?

[stark tide]

how do i animate a blueprint component in sequencer

[sullen oar]

Im doing a spline system for a power line, is there any way i can select based off a Blueprint or does it have to be a static mesh?
On a Blueprint, is there no way to have a Socket?

[dawn gazelle]

Sockets are something that are defined on meshes. You could add a scene component for positioning if that's what you're trying to figure out by having a socket in a blueprint. To retrieve the scene component "socket" you can do a get component by class or tag but by tag would probably be better if you're going to have multiple scene component "sockets" so you can name them using the tag.

[sullen oar]

Hmm,
So for example, i have this Wire Support,

and i have iton this blueprint

if that makes sense

[dawn gazelle]

Not sure what you're getting at then for needing a socket on a blueprint. The mesh itself has those two sockets defined (Cable1 and Cable2). So you should be able to get a reference to the sockets directly from the mesh, including their position or their full transform.

[sullen oar]

yea, i set those on the mesh, and will try that in a moment, and let you know,

[open crypt]

@dawn gazelle can you see my screenshot and advise why my possess isn't working? I was using a level sequencer before and it was switching but now it's not (really shouldn't matter because I'm just using the camera actor, i probably hooked it up wrong)

[dawn gazelle]

You are telling the player controller to possess the pawn they are already controlling.

[trim matrix]

can a function in a blueprint class be made static like in c++

[open crypt]

I wonder what I was doing before that made it work - this is an actor BP with a camera component, I want to switch to that perspective

[sullen oar]

I solved my issue above,
Just wondering this now

1. Setting the texture on the spline, (Auto populate with material)
2. being able to select the mesh rather than it random select, so say point 1, 2, 4, 5 do mesh 1, and point 2 do mesh 2 for example.

if that makes sense

[prisma stag]

Hello, I'm trying some code I did and have been having some problems. What I want to happen is for it to control the pitch and roll of a cube and when you move the mouse it will rotate the cube in that respective direction.

However, what is happening is it seems it is setting the rotation to the axis value from the mouse so based on how fast I move the mouse, the higher the rotation, then when I stop moving the cube goes back flat.

[runic parrot]

Hi! does anyone know if it's posible to detect drag on a button?

[open crypt]

I think it goes back because the pitch of the mouse moves back to zero when you aren't moving it

You probably want to try "add relative offset" instead of setting the rotation, play with that and see if it works for you

[open crypt]

yes, just check youtube for that exact phrase

[runic parrot]

you sure? i have been looking for it and couldn't find it. i can make it work with a image, but not with a button

[prisma stag]

I dont think that is the problem as Im adding it to the current rotation of that actor so even if it was zero, it should move it back.

[open crypt]

Just try it and see - it can be wonky using set rotation

[prisma stag]

Adding an offset move the actor, I only want it to rotate. I also tried addactorworldrotation but to no avail.

[sand shore]

Technically no. If you just want it accessible anywhere without a specific reference, put the function in a Blueprint Function Library.

[warm ermine]

Would anyone know anything about blend spaces by enums?

[pine trellis]

Can someone help? I keep getting an infinite loop on this code here but if I remove the true it wont work anymore, what else can I do to keep the code the same without getting t he infinite loop?

[dawn gazelle]

Loop through your starts, check which ones are valid first and add them to a new array if they are, then select via random the one to use from that new array.

[cyan rapids]

[fiery lark]

Okay guys, I have a child blueprint that I have set so that when an event is called, it increases the damage. However, everytime it is spawned it uses the same damage as it originally was, why is this?

[dawn gazelle]

Each instance of a blueprint has its own values, all of which are normally set to use their default values as defined in the blueprint when they are spawned. You can set a variable to "expose on spawn" and "instance editable" which would allow you to set a value within the blueprint when spawning it.

[fiery lark]

Ohhh okay, thank you

@dawn gazelle bro u just saved my life, thank you so much

[proud sable]

I've been trying to figure out how this works for a while now but I'm just not getting it. When casting to a blueprint, what determines the object I should use as the input? Especially when it's not obvious. I'm trying to get the wind speed from a weather blueprint but I have absolutely no idea what object it would inherit(?) from to get the value.

[severe turret]

the weather blueprint object with the wind value inside it.

[proud sable]

I'm definitely misunderstanding, sorry. If I place the blueprint in my scene, and I want to cast to that blueprint which has the value I want, I use that same blueprint as the object input?

[dawn gazelle]

Casting is only a means of taking a less specific reference and making it a more specific reference of the desired class so that you can access the more specific class' variables and functions.

For example, you place a Character in the editor - it can be considered an "Actor", a "Pawn" or a "Character" or even "Your Specific Character Blueprint". The latter being the most specific.

If you can get a reference to that actor, say by doing an OnOverlap event where you get a reference to "Other Actor" all that is giving you is an "Actor" reference, so you can't reference any values or access any functions from say "Your Specific Character Blueprint", so then you attempt to cast to "Your Specific Character Blueprint" and if the cast succeeds, you can then reference the variables and access the functions of that particular instance of "Your Specific Character Blueprint".

[tiny meteor]

hi, is there a multi-cast node in blueprint

for example, you can specify a bunch of classes and branch depending on which class it is

or do I need to chain them together

[dawn gazelle]

No at least not in a syntactically good way. To do it the clean way, you have to work VIA Inheritance. Using the example I gave just above your post, you could theoretically get a reference and cast to "Character" which any character including "Your Specific Character Blueprint" would be valid, but you can only access variables that would available at the "Character" level.

To make it a bit more clear...
Say you created a master "Character" class called "MyFighterClass" you then create child classes of this class, like "Kickboxer", "Swordsman", "KungFuMan". Then you could also create another class based on character called "MyEnemyClasses" then child those to things like "Zombie", "Bigfoot" and "Skelebones"

If you have a reference to an object which is a "Swordsman" but it is only an "Actor" reference, (again say from an Overlap event) you can cast to "MyFighterClass" and you would get a valid cast, but if you tried to cast that same reference to "MyEnemyClasses" it would fail.

[proud sable]

I think I see, casting for some reason has been the steepest learning curve for me so far in UE4 so I'm sorry if I'm way off here.

So far I've only used casting to get values from within a hierarchy (e.g. an instanced character needs a variable from the parent character blueprint. Every tutorial I've seen uses "get player character" as the input so I've been struggling when that doesn't fit).

If I wanted something from a completely unrelated blueprint, say that character needs the wind speed from the weather blueprint, should I still be casting for that value and using another method like GetAllActorsOfClass or is there another method of communicating values between blueprints that wouldn't normally interact?

[dawn gazelle]

There are very many ways of getting references to objects, and it all depends on the scenario which is the best way to use.

If they're both objects that you place within the world before game start, then you can create a variable that stores a reference of the specific object that you can set as "Instance Editable". Then you select the object in the world in the editor that needs the reference and you'll have the ability to select a reference which should then be selectable so long as you've placed it in the world as well.

If it's something you're spawning in, you can feed in a reference by setting the "Owner" variable to the thing that is spawning it (usually by way of a reference to "Self") and selecting "Get Owner" on the object was spawned, or, you can again create a variable reference of the specific object type on the newly spawning object, setting it to "Instance Editable" and "Exposed on Spawn" which will then give you a pin on the spawn actor node for that variable that again, you could feed in a reference to "Self" into.

If you have no other options, using "Get Actor of Class" is fine, so long as you're not doing it all the time - especially if it's something that could be done on begin play and saved in a reference as it doesn't really get removed and recreated, so then you can just use that reference you've saved.

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

[dawn gazelle]

I take this back somewhat - you do have the option of creating a Blueprint Interface, which allows you to pass through any reference, and so long as that class implements that interface, it can execute what it needs to on its end or return any values as you define in the interface.

[proud sable]

Thank you, I'll save this and look into each part. Until now I thought casting was the only option so this helps a ton

[hybrid ether]

Quick question. If i create blueprint interface for player I can call those functions by using get player character. But if I have child component in player character how can I call those interface functions? For example get player character -> get child actors -> get that child to target pin where that interface is used?

[tiny meteor]

okay, one other question

if I have a float between 0-1, I need to return a series of ints depending on the float value

for example if it's between 1-0.7, return 1, 0.7-0.5, reutrn 2 etc

which is the best way to do that?

[hybrid ether]

Thanks! is that better than this?

[dawn gazelle]

Not specifically. My example would get all the child actors who implement the interface to do it. Yours would only get the first one with the specific tag. Both have their uses 🙂

[tiny meteor]

trying something like this for now, but not sure if there is a better way

also I kinda need to make non-linear lerp values

100%, 75%, 25%

[analog ridge]

every time I create a new function the one before it in the my blueprint tab just does the same edits. So if I duplicate it and make something from .05 to .1 the first one will go to .1 Or when I create a blank function the one before becomes blank until i delete it, then it comes back

[knotty ore]

Hey guys, I've been googling for a while now but can't find an answer outside of C++ stuff (looking for BP).
Is there an easy way I can figure out if one sphere /circle (don't care about Z) is completely inside another circle?
Think the overlapping actors function, but the object needs to be completely inside, rather than just touching.

[gentle urchin]

Is one smaller than the other ?

So inside means 100% inside of a bigger one ?

[knotty ore]

Yep, varying size. I'm just playing around with prototyping one of those Hole.io type games

[gentle urchin]

Use the overlap check, normalize locations, then do a manual check of bounds in the direction(s) that is furthest from center of the bigger one

F.ex a small sphere of bounds 20 (10 in each direction) must be more than 10 away from the big spheres (location - bounds)

Horrible explanation but.. yeah 🤔😅

[knotty ore]

Haha, its all good, I'm just completely retarded 😂

[gentle urchin]

https://amp.reddit.com/r/unrealengine/comments/51y5vx/question_how_to_check_if_a_mesh_is_entirely/

Found another method here a few comments down

Compariong location+bound on each of them. If result is negative, its completely inside

[knotty ore]

If you want to check with boxes, or spheres you can get the world location and then add the dimensions to the location for both objects. Then substract the result from the object from the result from the reference object. If the result is negative it is inside if it is positive it is not inside.
Yeah, that's the closest I've gotten to an answer, but I can't figure out how to dump that into BP

Like, I can get distance from object to another easily, but including the radius of each object in that equation is 🤷‍♂️

[gentle urchin]

Distance can maximum be bigspheres bound minus smallspheres bound

Do ease the function, you probably can ditch the entire sphere.

Go for 2d location math instead

[knotty ore]

how do i get the bounds of a sphere though? A square is easier because its minX/minY maxX/maxY
Add the sphere radius to the center location and also subtract it from the center location?

[gentle urchin]

Bounds of a sphere is just its radius

[knotty ore]

so like this, right? but then I've got two vector values I dunno what to do with

[sand shore]

First just get the distance between them. Then, subtract each radius

if the result is <= 0 they are touching or overlapping

[knotty ore]

That gives me -70

Player sphere radius is 50, object sphere radius is 20

[sand shore]

Right

cause you're on top of it

You can actually use this to determine how close to the center you are as well - I don't know what you're solving for, but I'd you have the radii touch you can get that to print 0

[knotty ore]

oh yes, ok, i think i understand what's happening with this now 😄 thank you guys!

[vernal parcel]

Hello! I'm new to Unreal engine, I have imported a character from Mixamo to Unreal (after adding root bone with blender). i wanted to do a dodge animation for my character but, even after enabling he root motion the character keep snapping back to its original location. any advice guys? should i do these kind of actions using Anim montage or in the state machine?

[teal dove]

Hey guys, does anyone know what this error means?

i can use this in an actor right? not just a level BP?

[ashen basin]

watched the first one

will watch next one

[maiden wadi]

@ashen basinOne thing to keep in mind that all an interface is is simply a different way to call functions on something besides casting to it. It's like giving something a second class in a way. But you still have to obtain a reference to it somehow and that has nothing to do with interfaces. If that's where you're having trouble, you need to consider things like SphereOverlapsActors, LineTrace, ShapeTraces, CollisionEvents, OverlapEvents, Saving references to things when you spawn them, learning how to get most native references to major game actors, etc.

[ashen basin]

all i wanna do is send a value from gamestate to client/actor

[maiden wadi]

That is replication/RPC territory. Networking is different.

[ashen basin]

from one bp to another

probably explains why im not getting any where

[maiden wadi]

To clarify, are you talking about using networking or no?

[ashen basin]

not at the moment but i dare say it will in future

i want to share gamestate event tick with clients

[maiden wadi]

If not. Then your Gamestate simply needs a reference to the actor. What is the other actor?

[ashen basin]

not the event tick but game time which will be server side gamestate

mad

[hexed cloak]

Is there a solution similar to "Random Point in Bounding Box" that would work for a 45 degree rotated rectangle? Using a box collision to set the origin and box extent.

[maiden wadi]

@ashen basinWrong function name, that was internal. GetGameState and GetServerWorldTimeSeconds Those are native.

[ashen basin]

yeah found them trying them out now thanks

[hybrid ether]

Hi. What is best way to debug these errors?

[maiden wadi]

@hexed cloakNot sure I am following correctly? The box extent should be rotate-able.

@hybrid ether Have you changed any C++ classes lately that have Blueprint childclasses?

[hexed cloak]

@maiden wadi I just can't figure out how to do that I guess. I have a 300x100 rectangle that I want to rotate 45degrees and then get a random point that is inside that rectangle.

[hybrid ether]

@hybrid ether No I haven't This is full blueprint project.

[maiden wadi]

@swift pewterConsider using their PlayerState instead, and create a delegate that broadcasts when the Playerstate's pawn changes. AI can update itself with that binding.

Controller would work too, even in multiplayer since AI is done serverside mostly. Pointer could be replicated, either way.

Brain melt.. what are those in BP?

Event Dispatcher

@hexed cloakThe Box Extent is what dictates your rectangle's facing from the origin. If memory serves, the exent will always be towards the upper right of the rectangle's forward facing. So technically.. Since Extent is already in local space, all you should have to do is rotate it by your 45degrees, and the use that in the function with the same Origin.

You're trying to rotate the rectangle 45Degrees left or right? On the Yaw Axis?

[hexed cloak]

Yaw

[maiden wadi]

Do you already have an origin and an extent from your rectangle?

[hexed cloak]

Yes

[maiden wadi]

Unless I'm mistaken, it should be as easy as this then.

[tight schooner]

See if there are any other warnings/errors in your output log and resolve those. Make sure all your BPs compile without problems. Maybe try #packaging too.

[trim matrix]

please anyone can tell me how to make in-game update option using blueprint

[teal dove]

@trim matrix Thanks for the answer 🙂

[grave apex]

how can I detect if an input is pressed while another input is currently being held down?

[shy trellis]

Hey I created a For Each SYNC Macro on Standard Macros. Whenever I try to use it I get "Can’t save because graph is linked to external object?" error. Is adding a macro to standard macros a bad idea?

[maiden wadi]

@swift pewterPersonally. I'm lazy. If you want the AI to always go after a player character then I'd write a simple function that just returns the non AI playerstates from Gamestate, get the best player for the AI to go after with a filtering function and go with that mostly. Less reliance on keeping a binding correct.

@grave apexYou check if the other key is held down during the input of the one currently being pressed.

Controller has a IsInputKeyDown function for that.

[tight schooner]

I've read that modifying standard macros is a no-no... I haven't tried it myself though to see what happens. I made my own macro and function libraries for my project.

[grave apex]

ah

ty

[trim matrix]

please someone tell me how to integrate in game update option

[shy trellis]

well that's weird

[grave apex]

I was only changing a duplicate

I think I made a while loop with a delay

[hexed cloak]

@maiden wadi I think the issue is that the box I'm using to do the rotation is a child of a parent actor. The parent gets rotated.

[shy trellis]

When I duplicate and edit It just causes the problem that I talked about

[trim matrix]

please someone tell me how to integrate in game update option

[olive sedge]

hi! Does one of you know how to get a vector that is plane to a normal? like the horizontal bar on top of the T, no matter how the T is rotated in 3D?

[grave apex]

what do you mean by "in game update option"?

like, if an update gets released, it would notify a player that a new update is out?

for the whole game?

[maiden wadi]

@olive sedgeIs LinePlaneIntersection(Origin&Normal) what you're looking for?

[grave apex]

?

[olive sedge]

@maiden wadi sounds exactly like what I'm looking for, I'll check it out

[trim matrix]

i want to add option inside the game to update it like epic games launcher

[hexed cloak]

@maiden wadi Looks like rotating the box extent changes its size, rather than just rotating the rectangle 45degrees

[maiden wadi]

That's odd. Extents should be in local space already.

[olive sedge]

@maiden wadi I don't think that's it. It returns where a plane crosses a line I think?
I basically need a plane that sits on top of a vector or more like the rotation of that plane (I want my vehicle to always be even with the ground)

like this: https://i.imgur.com/o5tRfUC.jpeg

but it falls apart with the roll of the track for some reason

[hexed cloak]

Yeah it just changes the size when you try to rotate the Extent. You can plug the code you sent in to a Draw Debug Box and see it change size when you change around the Yaw on the RotateVector

[maiden wadi]

@olive sedgeAh. So you'd need to trace, hit the ground, get the normal, and make that the vehicle's new up vector while probably setting the forward vector to the closes thing you can get to the car's current facing based on the normal's rotation.

[olive sedge]

@maiden wadi very much exactly this. and that's what I'm doing but it falls apart on the tighter bends: https://i.imgur.com/DdtWapE.jpeg

[maiden wadi]

@hexed cloakSec opening a non work project to test that. Been working with UI for far too long.

[hexed cloak]

[maiden wadi]

@trim matrix You're asking for things that have no bearing on Blueprints, in the blueprint channel. If you want your game to be updatable, consider releasing on Steam. Makes it very easy to handle that.

[trim matrix]

is it not possible to use blueprints to update it

without going to any external website

you can simply tell me yes or no

[icy dragon]

No.

@hexed cloakAh. There we go. I don't know why I assumed that with BoxExtent. Just needs a couple of extra steps to work.

[hexed cloak]

Will try that right now

Thank you ❤️

Never would have figured that out lol

[maiden wadi]

@olive sedgeQuestion about that. How do the cars handle on the track? Do they always face the direction of the track along the spline?

@hexed cloakIt's pretty simple in the end. It just uses the extent's local space to find a point around that world origin vector. The minus converts the newly found random point back into the local space of the origin, then it's rotated around that origin since it's in local space. Added back to the origin to put it back in world space.

@olive sedgeMakeRotFromZX may be enough. I'm uncertain. Hard to test that without a setup. Z would be the normal from the trace, X would be the directional along the spline, or the vehicle's velocity, or the vehicle's current forward vector,.

[ashen basin]

how do i print string on gamestate bp

i know how to print string but doesnt show

is there a console or something will be in

[dawn gazelle]

If your print string isn't firing, perhaps your event that it is connected to isn't firing?

[ashen basin]

connected to event tick

[dawn gazelle]

Is event tick firing?

[ashen basin]

why wouldnt it be

[dawn gazelle]

You have disabled tick. You haven't defined the appropriate gamestate in your game mode. You're not using the right game state class for your game mode.

Could be any of these.

[ashen basin]

ok thanks

For each point do distance to last point

Add them together

Hey guys. I have an issue with Mouse events "double-firing".

I have a UI which generates mouse down events when the player clicks a border (maybe better to use a button here?). It works great. I also have a mouse event when the player clicks a mesh in the world, which also works great.

However, if the widget is directly above the mesh, clicking the widget will execute the UI mouse down event first, then the mesh event. How can I prevent this from happening? I only ever want it to fire the UI mouse events, I NEVER want the mouse events to go "though" the UI

Is it possible that moving my folder containing my HUD blueprint and widgets would break functionality somehow? I had everything set up and working and organized things into new folders. As far as I can see everything is still referenced properly but the HUD no longer shows up when the game starts and I can't figure out why. Any idea how I can figure out what's wrong?

[sick sapphire]

are those trace channels or object channels
i want to customize them

[pastel geyser]

can someone come to the unreal hangout vc i need some help with my bp

[proud sable]

Yeah, that's what I did. I moved from the default ThirdPersonGameMode folder into a more permanent folder within the content browser and haven't been able to get the HUD back since. The widgets look the same in the designer and the HUD class is set properly in the game mode blueprint but I still can't get it to show up. Tried recreating any nodes that reference the HUD/Widget blueprints but it's still missing :/

Ah damn. I don't remember the exact paths I had before so I'm not sure how to fully revert it. Things were pretty messy so this was all just to clean up the folder structures

[blissful cosmos]

Could you elaborate on this? Note sure I understand

[rigid tartan]

Is there a way to keep the current instance of my player character when opening a level instead of making a new one? I have a login page in an initial level and I open a new level (by name) once the user signs in, but this seems to replace them with a new character object and thus loses some important user information that I need.

[proud sable]

This put me on the right track, thanks! Noticed in the recent levels I had two, I had accidentally moved the level+game mode blueprints. Moved the "new" ones to their old location according to the path in the recent levels tooltip and the HUD appeared again properly

[icy dragon]

I'm not sure with the multiplayer ramifications, but try storing the values in Game Instance.

[rigid tartan]

Ah I see, didn't know something like that existed

[icy dragon]

Game Instance persist through level "travels", and only destroyed when the player quits the game.

[rigid tartan]

Alright I'll use that then, thanks!

[proud sable]

I'll look into it thanks, I've been meaning to be more careful but kept putting it off. This is a good wake up call

Hey everyone, I'm trying to set up a way to have a thin collision box that stretches between two positions in the world. I'm having a bit of trouble figuring out how to do that. Any suggestions on the setup in order to make it happen?

[hallow pond]

Change the Input Mode to UI Only. Or on your Class Settings you can set to Capture Input (I think Widgets have that too).

[maiden wadi]

@blissful cosmos Most likely cause of this is usually because you're not replying the event as Handled in the widget. Which allows it to follow through the widget tree until it hits the viewport canvas, which then tries to click on the actors in the world.

[blissful cosmos]

@maiden wadi Do I need to do more?

[maiden wadi]

Don't use MakeEventReply. Disconnect that, drag backwards from ReturnValue, and type Handled

[blissful cosmos]

This was the issue. Thanks a ton - saved me a ton of headache and workarounds

[maiden wadi]

What happens is that the reply from that will determine if you want to allow the mouse click to run further up the widget hierarchy. this allows UI to stop mouse clicks from getting to the game viewport and causing in game selection while in widgets. Alternatively, you can have multiple widgets do things on click by returning unhandled in them. but eventually if you don't handle the click events, they'll reach the game viewport and that is where PlayerControllers do their onClick events and such.

[clear osprey]

By default a boolean is true right which is created using BP?

[maiden wadi]

@clear ospreyNot usually. Booleans will generally default to false. But if you're adding variables to something, you should check it's state anyhow.

[green eagle]

@The_Nikso#8355 theres a better channel on the server to ask that. But google up or search youtube for "importing model to ue4" lots of "how to"'s on that all over the place. Might even find specific ones to your 3d modelling software. I know if the file type isn't correct. Or if I forget to set something to be a geometry in Houdini that ill get issues trying to import.

Good luck

[clear osprey]

yes I sets its condition in properties to true and now I don't need to perform prone before walking around

[green eagle]

oh he left Unreal Slackers all together it looks like..

[formal dagger]

ok so i'm stuck (again). So basically, i want my character to plant a seed which gonna turn into a vegetable. I don't know how to say to ue that "this" seed = "this" vegetable. (automaticly if possible). I'm stuck at the spawn actor of the vegetable

[clear osprey]

and in UE 4.25 this is true by default while I am not using it with along NOT

[green eagle]

Use variables

[green eagle]

Could even set up an interface bp if you have a lot of variety or a spreadsheet class

[clear osprey]

This Enable Move need to be true to walk right/forward

but still after performing prone why this is changing its state to true this is a mystery of UE

[formal dagger]

i think the solution is with the datatables, prob is i don't know how to make 2 datatables communicate. it's something about {} but i can't find a good tutorial to explain all this

[green eagle]

so when player "uses seed" the interface checks if "tilled land" is overlaping "seed actor" then adds "plant actor" to "tilled land" it takes the "seed actor - type" and applies it to "plant actor" then deletes seed

[green eagle]

Let me see if I can find something that might help.

[formal dagger]

yes, it's just the seed X = vegetable X that i miss, i don't know where to set it

[green eagle]

So in an interface BP you can set inputs and outputs that can relay data between one Class/Actor to the other being communicated with.

crappy example but it was on hand

So the first image you have the interact relay pulling the "scene component" data from the "characterBP" and it sends that info to the "Resource BP" letting it know where on actor 1(character) to put component from actor b(resource)

You could have an input for the variable "type of seed" go into the message and when it decides to spawn the actor "crop" in the Tilled land or crop actor BPs you have it pull "type of crop" from that input.

Does that make any sense? I can try to put together something for better clarity

@formal dagger so in the interact function you would want it to check the string through an array, have it match it to a "seed" listed and then it would automatically populate the right plant.

Guys is UE support getting the character input speed values through character stats using real time BP arrays on server side to avoid cheats?

and the replication of those arrays will be another task

This is the Plan but not sure it will work or not

that could work in principle but that's a lot of data authoring

[clear osprey]

yes

[maiden wadi]

Maps and gameplaytags are going to simplify and speed that up by a fuckton.

[sand shore]

Yeah you'd be able to tag stuff like "Heavy" "cumbersome" and get different modifiers.

It's a wholly different approach

If you need precision though what you're blocking out is going to be more straightforward

[clear osprey]

this data will be monitored in real time

later the vehicle support will be added

Are you using the editor from the launcher, and not built from source code?

Hi I wonder if anyone can help me, I'm trying to set a parameter in a material in a widget (this is for a custom progress bar). The debug text proves that the number is what I think it is, but the material still uses the default value. Am I doing something wrong here?

[storm dove]

hi guys, i have a base button widget i use in all my widgets, can i set one public variable to defaults on all buttons?

[icy dragon]

You can create user widget of that button and substitute the stock button widget.

[storm dove]

i already did

i have a variable "opacity"

i set it to 1 in my master widget

but all other buttons in my project are still 0.5

i want to set them all to default 1

i guess i can delete old variable and create a new one but thats barbaric

[novel phoenix]

Hey guys!
Shouldn't this change the location of WeaponMesh only for Y and Z and make the X stay the same? Am I doing something wrong here? I know this is a harder way to do it, I just wanted to see if it is right.

[storm dove]

why would x stay the same?

[novel phoenix]

(1, 0, 0) * Old Weapon Position + (0, 1, 1) * New Weapon Position

[dawn gazelle]

Are you sure Prograss Bar Image and the return value from Get Dynamic Material are valid?

[novel phoenix]

the first thing should result (Old Weapon Position.X, 0, 0)

• (0, New Weapon Position.Y, New Weapon Position.Z)

[subtle valve]

@dawn gazelle Yes, in fact I have hooked up debug text to the material instance itself to get the parameter I'm changing, the parameter itself is actually updating. It's just not affecting the image.

[novel phoenix]

So, it should equal (Old Weapon Position.X, New Weapon Position.Y, NewWeaponPosition.Z)

the X doesn't change

only Y and Z

am I right?

[subtle valve]

@dawn gazelle

Manually updating the value either in the material instance or in the material itself DOES affect the final image. So this is either a very strange bug or I'm missing something fundamental.

[analog ridge]

so every time I create a new function the one before it just has the same edits. So if I duplicate the first function and make something from .05 to .1 the first one will go to .1 Or when I create a blank function the one before becomes blank until I delete it, then it comes back. I'm following a tutorial and I've done exactly what he is doing. Is this a version issue? I'm using 4.26.2

[subtle valve]

Actually, let me correct that, manually updating the value in the material instance doesnt affect the final image. It seems to only care about what is set as the default value in the material.

[dawn gazelle]

So testing on my end, what you have there is perfectly fine. Nothing wrong with the code.

I added just a user interface material with a parameter exposed and it changed over time as expected.

[subtle valve]

Yep the material domain for this is set to user interface too

I mean here's the whole material if it helps, the Progress param is what I'm changing

[frank nest]

I have this sphere where I apply force and it moves when I posses it, I want a saddle on it but as you can see the saddle that is parented to it the sphere will move with it. I am hoping to have it stay on top but if I dont have it parented it just stays in world space. Any ideas? 🙂

[subtle valve]

@frank nest I believe you'll need to store the relative location on beginplay, then set the relative location every tick

same with rotation, though you can set a component to always use world rotation

[storm dove]

what exactly do you mean?

[subtle valve]

@dawn gazelle Ah I found my problem! In the object that has my radial progress bar as a component, I had set the material as well as the widget reference. I cleared the material and it works now.

This bit was set. Looks like it was overriding what the widget was updating.

Thanks for the help!

What's the parent class of the BP this function came from? Look at the top right corner of the BP editor.

[trim matrix]

its Take Commands

im a complete noob

[icy dragon]

Is this "Take Command" class inherited / child of "BP_TriggaTrey_UseThisOne" class?

Because you're using Self as the cast input, which is referring to the BP itself.

[trim matrix]

oooo lol its not related at all

that make sense

i'm trying to connect to another blueprint entirely

[icy dragon]

Also, you don't need casting from Self, as the functions from the parent class can be called right away.

[trim matrix]

okay that makes sense

so what im trying to is from TakeCommands blueprint i want to toggle visibility of a hat in my character blueprint

[icy dragon]

In that case, you can use either Event Dispatchers (which is cross BP event execution, and more specific execution) or Blueprint Interface (which is cross BP function execution, and it's "one for all" execution)

[trim matrix]

Yeah that makes sense I'll look it up. Thanks Homie! I'll be back if i scuff again 🙂

My "DestroyActor" node isn't working. It's hooked up, but it doesn't actually delete the actor when it's called.

Can anyone explain it to me, please?

[tight schooner]

@nova ledge Destroying the actor should take it out of play immediately so idk why you're not seeing that happen. Try not to run any nodes on it after DestroyActor is called.

Fwiw you can call GC manually. I think the node is called Collect Garbage

is there a good way to have a widget position a crosshair in 2d screen space so that it always covers a point in the game world. IE - I have a tank, I run a quick formula to find where its turret is aiming. Assuming the player is looking at where the tank turret is aiming, could I have a widget place a crosshair over that position and update it as the tanks turret changes where it is facing.

[sleek pecan]

I think you'd just raycast from the turret in the direction it is pointing (with some kind of backstop maybe / maximum distance) and then project from world to screen space https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/ProjectWorldtoScreen/

[surreal delta]

Hey if anyone might be able to help me out I'm trying to repurpose a "ledge grab" functionality into an activation event for the player.

In short, we have a ledge grab mechanic as part of the player's core functions. Part of this group project is not to add or edit any of these mechanics directly inside of the player blueprint.

I need to reference that the player is in this animation state after overlapping with the handlebar. I already have the zipline animation setup, I just need a way to limit some of the parent functionality:

• Remove the tooltip text, as is unrelated.
• Prevent the player from climbing up / dropping down, but still can control the camera
• Have the player automatically drop down after the timeline is complete.

TLDR; I need a way to reference the ledge grab mechanic as an event without editing the player's core blueprint. Everything functions in BP_Zipline.

I'm sure it would be easier to show how everything is setup in a voice call / screenshare. Help would be very appreciated thank you 😄

[vocal elm]

is there a BP equivalent for FQuat::FindBetweenNormals?

[surreal peak]

Hm, do we have Quats in BPs by now?

[gentle urchin]

What you could and probably should do is simply doing an isvalid check of the variable, and get player pawn cast to yourpawnclass and save it again

Most of the time the isvalid will return valid so

I dont imagine it giving you any issues

Either that or you can create a global reset player event (unless one can already bind to gamemodes event)

One time. Then its valid untill the next death of the player

Other option is to not destroy playerpawn

Just play death, then hide the body

Reusing it could mean less work setting up references and such

Not sure how thats potentially better than when needed but sure

Restartplayer event could make sense in several ways

How are you restarting the player anyways

But how is that handled? And where?

Its fine, got it ^^

guess one cant bind to the default gamemode , so would need custom gamemode (which you probably have) and have a dispatcher for the player restart there

If you'd wanna go with that method.

Event driven is surely the best way to go in most cases

what you do ofc, could be pretty simple aswell !

When you gather the original reference to the player,

bind to event destroyed

then on destroyed start a looping timer with like 1-2 sec timer, and try to reset the variable . If it fails, continue to check. if it succeds, stop checking, and rebind to destroyed

[sand shore]

the data type has been exposed for a while but not really any functions

[gentle urchin]

something like this -ish

not sure if you must unbind from a destroyed actor

wouldnt think so

yeah

you must have matching signature

so going from delegate auto fixes that

[fiery swallow]

it needs to be higher than 0.0 to fire buddy

[gentle urchin]

you messed up for sure

ignore the input pin

and just let it use the get player character to pick up the reference

[fiery swallow]

You should probably use an event dispatcher for when dead and when respawned

[gentle urchin]

target on bind should be the character , sorry, forgot to connect

the newest ref (seeing as the cast returns is valid) will always be valid when set

my way felt pretty hacky

i'd say this looks cleaner 😛

[trim matrix]

i got more drawcalls if there is less foliage visible

is there any clustering or something like that ?

ah sry more drawcalls ^^

[trim matrix]

Can I add new splinepoints based on lenght ?:) . Trying to create smoth curvs at runtime 😋 .

Something like this 🙂

[gentle urchin]

Wasn't there issues with saving structs for a while ?

And also, are you sure the data is actually updated in the struct in the first place?

Verifying with prints f.ex

originally, or after load ?

show how you update them

and the leveling part

guess i miss-read this part then

PrimaryWeapon is a valid variable aswell? no errors ?

could be, its hard to say from what you've shown

So, are you updating two set of structs for the same variables? one in the component, and one in the playerchar?

[timid nimbus]

Hey, I'm new to UE and I'm making a game in which you can fly

But the thing is I dont really know how to do that

(With blueprints)

So is there a good tutorial or something on that topic?

I'm using UE5

I think they removed it

Do u have any other idea?

Oh, ok

BTW I ment any idea on how i can do the flying thing

Thanks

[upbeat otter]

how do you cast to an child ai bp?

i cant use "get all actors" because its gets every single actor in my scene

unless can I use a for loop or something?

here's what I currently have

[faint pasture]

@upbeat otter What are you trying to do? Which actor are you trying to get?

[burnt nest]

Noob question incoming! Let's use a strategy game as an example; let's say I have 100 resources when I put down a Save Game, which of course I want to restore when loading later on.
Can I just keep that variable in the player, or would that be in the Game State?

[gentle urchin]

Isnt playerstate replicated?

[novel ice]

Hey there, I have a problem with For Loop...
I am activating a notify in anim montage, which does this

[gentle urchin]

Meaning you could be open for cheating if you let this data replicate?

[novel ice]

For some reason, For Loop just doesn't work! I mean, it makes the thing only one time and after that prints string

[obtuse herald]

A PlayerState is replicated to the corresponding player, but only the authority can modify it afaik

[novel ice]

There is a delay

[gentle urchin]

Was more thinking that other players could find out about other players resources

[novel ice]

And after a delay there is another projectile spawn

[gentle urchin]

Since the data will be avaliable for all players on all clients

[burnt nest]

thanks captain! ❤️

[gentle urchin]

If thats the case then I've either read it wrong or been told wrong. From my understanding, playerstate was replicated to all players

[primal smelt]

Out of curiosity, is there a way to change the object type for collision of a line or box trace in blueprints? I assume you could edit the engine source code if not.

[gentle urchin]

If you're refering to channels they can be added under projectsettings

[primal smelt]

AH gotcha, by default I assume it's just visibility and camera? They were the only two available in a line trace by channel node

[gentle urchin]

Correct. You can add up to 15 or so custom channels

[primal smelt]

I got somewhat confused because a box trace was not hitting an object unless I enabled overlap for world dynamic - so I thought the method would be changing a line trace's object type!

(or a box trace in this instance)

[proud sable]

Is there a way to set the color of an image widget to grayscale with a binding? I want to set an ability icon to grayscale when the character doesn't have enough mana to use it. I have this so far which darkens it but it's not exactly the effect I'm going for

[nova ledge]

Okay, I'm using UE5 so I don't know if this needs to be reported to Epic Games to fix or not as of yet, so I'm just gonna ask about UE4 here real quick. So I'm using a blueprint interface to call a function. When a certain event is fired, I want the game to collect the garbage. I figured it would be best to put that in the Level Blueprint. However, when I put the event in the level blueprint and compile it, I get an error saying that it already exists in '[map name]', and that another one cannot be generated from that one. The only time I put that in any blueprint was in the level blueprint and a character blueprint to call the event... am I misusing it? Or is it just a bug in UE5 that I should report?

[pale tulip]

Hi, you know how to display a rewarded ad (admob) in ue4 without plugin?

[sand shore]

levels probably shouldn't implement interfaces and maybe that's the error.

The reason why is because you can't even get a generic reference to a level script actor in BP (by default)

[nova ledge]

I thank you for your thoughts, but if it's not intended for interfaces, then why do they make it where you can add interfaces to the level blueprint under the class settings?

[trim matrix]

How to get structure variable name?

I don't want the value only i need name as well.

[novel ice]

Huh... it prints 10 times!

So what can I do?

[fleet vessel]

How do I make my animation into a variable?

[sand shore]

I mean try not doing an interface and see

It's a special case class, maybe the interface isn't your issue

but to not try it out of hand? /shrug

but also show me you using the interface on a level BP from outside that level BP

[fleet vessel]

Hello Someone please help me

I can't find my basic anhimation as a variable

Please help

[tight schooner]

I've heard of people using components as pseudo-interfaces in this channel before. I want to dabble in it. Is this the gist of how it works? Checking if an actor has a component, and then getting variables / calling functions on it?

[burnt nest]

Components can be used to create certain systems that you can then attach to different actors rather than building them directly into a single pawn, yes. So that's pretty much how it can be used.

[tight schooner]

Thanks. I'm trying to unwind a web of BPIs I've spun in my current project; gradually replacing functionality with proper base classes, and I was thinking components could handle the "blueprint communication" that cuts across class hierarchies.

[flint lion]

Hi guys, I'm having an issue where adding an ActorComponent by using AddOwnedComponent in C++ but after creating a blueprint, that AC details doesn't show anything, I tried reopening the engine, recreating the blueprint but didn't work. Anyone know how to fix this?

[last abyss]

you can't find your animation because you have a user widget reference, not a 'Widgets_Controls' reference

[fleet vessel]

How do I convert it to that reference?

[flint lion]

SetupAttachment only works for SceneComponent, isn't it?

[last abyss]

cast to it, then u get a reference

[flint lion]

InventoryComp = CreateDefaultSubobject<UInventoryComponent (TEXT("InventoryComp"));
    AddOwnedComponent(InventoryComp);

[last abyss]

and make object in the cast the user widget ref u have

[fleet vessel]

cast to ....?

sorry, im new

[last abyss]

cast to widgets_controls in your case

[flint lion]

I got the component added as inherited in the blueprint, but it doesn't show anything in Details panel

[fleet vessel]

but if I look into the tutorial, the icon of widget is different to mine

means the base classs might be different

[last abyss]

user widget is a parent of your 'widgets_controls' reference. The parent doesn't know the functions, like your animation, on the child (widgets_controls). But the child knows the functions on the parent (user widget)

[fleet vessel]

hmmm

ok i trie

[last abyss]

if you're following a tutorial, try see if you did something different or read/listen through the entire thing if you haven't already. sometimes they explain it later on, not while they're doing it.

[fleet vessel]

yeah, for that I'll have to go 2 vedios back

but that looks like the only option

[sand yacht]

I really cant seem to figure out how to fix these

[fleet vessel]

Can I reparent the class in some way possible?

[last abyss]

you can change the reference type from user widget to widgets controls, or instead you can cast to widgets controls from the user widget reference you have

if you need to reparent the class, you can go in the class settings (in the ui graph toolbar) and reparent it there.

[fleet vessel]

is this how it's supposed to happen? Still can't find the animation 'OpenClose'

[sonic pine]

Hiho, I have a few questions about the translation function in UE4.
Unfortunately I have a little problem with that. Is anyone familiar with it?

Unfortunately, I don't know which topic this would fit exactly, so I'll post it here ^^

i have 3 defferent lists

The problem is i have transleted this part in the Equipment_Ring list but now i have to translate all again in the new list... why?

[last abyss]

right, the animation is called OpenClose so if you 'get OpenClose' off of the 'As Widget Controls' you will get the animation and you can plug that in.

[fleet vessel]

Is this how it's supposed to be set up?

[last abyss]

'supposed to be' is a rough statement because there's many ways to do it. but in this case, it should work.

[fleet vessel]

oooh found it

[fleet vessel]

sowwy

But thanks found it

thank you

[last abyss]

don't have to apologize, we're here to help

[fleet vessel]

I just hope this different class widget doesn't give me any problems

And it worked completely fine

[gentle urchin]

The error accessed none means that your reference variable is null

Meaning, it's not set to any specific object/actor

A variable reference is by default empty and must be set by one means or another

[cinder shell]

Guys, I having a strange problem with opacity of translucent materials, what caused by PostProcess. So sky is appears like fully transparent on those materials... I can't figure out what I did wrong. It's a simple depth fog.

https://blueprintue.com/blueprint/5vmfqblj/ here's postprocess

[sand yacht]

Am I not setting it in the Set Handle Location node?

[proud sable]

Trying to streamline my HUD blueprint a bit. In the event graph I set variables for the active party member as well as the uncontrolled AI party members. My functions use these to get attributes/icons for each character. Doing it this way is giving me errors though since the functions seem to call before the variables are set. Is this something I should ignore or try to troubleshoot? As far as I can see it's not causing any perceivable issues and only happen in the first frames of running the game.

[gentle urchin]

The variable "physicshandle" is empty for sure

[gentle urchin]

You could add simple "is valid" checks to your called functions to avoid them. Getting rid of them now (despite no percievable issue) will help you stay on top of bugs and issues, and not the other way around. Atleast thats my take on it

[gentle urchin]

It appears to be a set of bindings aswell, based on the amount of errors

[gentle urchin]

Its updated there. Question then is, are you calling it somewhere before its set, or are you somehow emptying it again before using it

[sand yacht]

let me check

\

[gentle urchin]

Right

[gentle urchin]

On tick id block the code if the handle isnt valid

No reason to run if you're missing key actor references

[sand yacht]

How would you do this exactly? Is there a node of some sort?

[gentle urchin]

Yes

The node is named "Is Valid"

Comes in two types. One bool. And one macro with is valid and is not valid

[sand yacht]

So in screenshot 2 I should add an is valid bool after releasing right mouse button setting it to false?

And on pressing rmb setting it to true

[gentle urchin]

On tick, id add it before updating the vector

Either as its own nodez or combine it for the branch

Hmm wait ..

Seems i didnt check all your code

Ah.

Yeah the problem is that you avtivate the bool before you know the code executed

[sand yacht]

the screenshot i sent at 9:49 is an extent of the last screenshot

[gentle urchin]

If tou move the "physics handle active" bool to AFTER adsing the component , i believe you should be fine

[sand yacht]

alright let me try

[gentle urchin]

Im ofc assuming that you turn the bool false if you ever destroy the handle

I believe you could direvtly replace it with checking if the physics handle is valid but i may be reading to fast.
/not grasping it properly

[sand yacht]

its too much code to send it entirely

but moving it after adding the component still gives me the error, but 10 times less

if that makes sense
