blueprint

[versed rune]

Yup, that's also a way to do it

[gentle urchin]

Not really, no

[hollow schooner]

After a restart, I managed to set it up. I changed it to "Hit Component" as I'll be adding some additional components to the car blueprint that I want selected that might not be the car.

Thanks again, your help is greatly appreciated

[versed rune]

Yep, that's a perfect use for components tag, good luck ^^

[hollow schooner]

Cheers!
Does anyone here by chance know how to make a Drop-down menu for the UI?

I have my paint colors but would like to store them in a type of "folder" which the user can select to then show the different color options. Just like the attached image

Or what I need to google? Cant find anything matching when I do a search

[limber parcel]

bruh

[gentle urchin]

Its an extremely specific thing to google. It looks like its just about toggling the display of another widget when the "folder" is clicked

Not sure what happens when you press brakes etc,

perhaps a "Widget Switcher" is suitable

[hollow schooner]

The icons just open up sub-menus to varient sets. The left square opens up color swabs, the brake allows color change too, the rim allows rim switching, etc

I already have the same setup, now I just want the UI to change. I'll look up widget switcher, thanks!

[humble flume]

Hey can anybody tell me that how can I make a dynamic crosshair like I want different type of crosshair for different weapon and that crosshair should spread when character move anybody know how to do that

[sand yacht]

For some reason this node only works when I'm clicking on the object rather than when I'm hovering over it

[limber parcel]

maybe its not focused or something

[sand yacht]

How would I focus it then?

[jagged stone]

Does anyone else have a problem where sometimes double clicking does not work for creating reroute nodes?

[tight schooner]

Can't say I've had that issue (UE 4.26 though)

are you running any node graph plugins? Just stabbing in the dark here

otherwise I got nothin'

[jagged stone]

I haven't changed any plugins for default, the rerouting works if i restart

Then it just randomly seems to die sometimes...then the only way to create reroutes is to drag them out

[tight schooner]

are you running dual monitors?

[jagged stone]

Yeah, oh weird, yeah if i drag the graph onto a different monitor it works

[tight schooner]

I don't have an explanation. I've just seen the UE editor act up on some dual monitor setups. Not sure if it's due to DPI scaling or what

[jagged stone]

So now to decide if i want to work with my head turned all the time, or use double click rerouting 😄

[limber parcel]

by clicking on that widget

u can probably force it in code too or something, i dont know much about UI stuff sadly

[sand yacht]

im not using ui, im trying to hover over an actor

[versed rune]

Lmao srsly that's a thing?

[limber parcel]

its a lie i would never use dropbox

🚮

[gentle urchin]

Swap primary monitor in windows settings 😄

[hollow schooner]

I got the widget switcher to work and also toggle on the visibility of the sub-menus.
The issue I am having, is that when one menu is open, and I want to open the other, I have to select the button twice. THe first time, it closes the currently open menu, and then on second click it finally opens the desired menu. Video attached.

This is what the widget switcher setup looks like now:

[midnight ravine]

I feel like I haven't changed anything, but now my character doesn't change pitch (the camera doesn't move up or down) based on mouse input.

Note that I can't use Use Pawn Control Rotation and haven't before anyway I think because I'm working on a multiplayer game (if I do this, the pitch is not replicated at all)

I'm at a total loss right now and have no clue where to even look to fix this.

The weird part is that the yaw works perfectly fine, but pitch is set up the exact way, so how come it doesn't work anymore?

(the pitch doesn't change even when just doing singleplayer stuff btw)

[tight schooner]

Maybe it does switch on the first click but you've hidden it? I'm not sure what's up. But what would happen if you bypassed the branch and went straight to Set Active

[gentle urchin]

The idea with the switcher

Is that it hides the not active ones

[tight schooner]

Maybe the fuller realization would be a double boolean (try the AND node), where it also checks if the button clicked corresponds to that index before toggling visibility

Cuz otherwise it's just always toggling visibility

[gentle urchin]

So whichever widget index is active is the only one displayed

[hollow schooner]

Yeah and that works, but I want to be able to close the menus, hence the current setup

Otherwise at least one menu will always be open

[hollow schooner]

then none of them are visible, as I need to set it as visible first

[sand yacht]

is it possible to Set local location of an actor instead of Adding Local location?

local offset*

[gentle urchin]

Just have an index empty (purely a invisible border)

[hollow schooner]

Big-brain move right there

Although, how would that let me toggle them on/off

Ah, I think I know how

[humble flume]

Hey can anybody tell me that how can I make a dynamic crosshair like I want different type of crosshair for different weapon and that crosshair should spread when character move anybody know how to do that

[hollow schooner]

Okay, no, I cant seem to figure it out. I tried to set the invisible widget as active if the selected button is already visible, but then for some reason, once clicked again, none of the menus pop up again 🧐

This was my idea, but that failed

[tawdry surge]

@sand yacht set relative location

[sand yacht]

thanks

[gentle urchin]

Personally id make custom buttons that can, on clicked, return their respective index aswell

You just need to check if current index != desired index

If they are the same, set index to 0

If they are inequal, then set to new value

[smoky elm]

Does the blueprint of anyone else also keep turning out like this 😂

[near wolf]

https://blueprintue.com/blueprint/p5zc-m__/

Can someone help me a little bit how can I use this blueprint for my decal ?

or this one

[last charm]

i need help, the IsPunching variable is in player controller because it gets triggered by a button, the problem is that i need that variable in my Animation BP because if the variable is true it triggers an animation.

i just need someone to tell me what that Target is

[tawdry surge]

It's the controller if thats where the bool lives

[copper steppe]

The target would be owning pawn->PlayerController

Unless you can get controller directly

[tawdry surge]

You'll have to cast it tho since the generic controller reference won't give you access to variables on your custom controller class

[hollow schooner]

How would I go about adding a sound when the door opens? Is that something I do in the Car blueprint?

Here's the door animation section in the Car BP

[hollow schooner]

Tidy and organized? 😉

[versed sun]

Add an Event Track to your timeline

[smoky elm]

Kinda like my coloring book from when I was an infant ngl

[last charm]

idk

[last charm]

ok it works but i cant get the button to work now

[copper steppe]

Which part of it? The button that changes the variable? Or the one that starts the animation?
What's up with the IsPunching & IsPunching2 though?

[last charm]

I just deleted IsPunching2 because it was useless

[copper steppe]

So, is the button press not detected? Or is it the code that's executing wrong?

[copper steppe]

That still won't work, since you can't cast a pawn, to a controller, you have to do either of these:

Where "PlayerCash" of course is you punch variable

[last charm]

Punch is set to LMB, this is in player controller

[last charm]

ill try

[hollow schooner]

When using the Timeline for sound, it plays the same sound when I reverse the animation (in this case to close the door). However, when revesring, it plays the same sound (from the start) when it reaches the end.

is there a way to tell it to use a different Event graph when the animation is reversed?

[tawdry surge]

Direction pin will return an enum you can use for a branch

[last charm]

none of those work, but the error says:

[copper steppe]

You have to connect it's execution pin:

[last charm]

and what can i connect it to

[copper steppe]

Well, I'd connect it when I need the variable.

Seeing as you are using it in a result pin, then maybe use "BlueprintInitializeAnimation", and then set it as a reference

Then you can just use it later

[last charm]

cant find "BlueprintInitializeAnimation"

[copper steppe]

You are in a animation blueprint right?

[last charm]

yes

in the state machine

[copper steppe]

Exit the statemachine, and go to the event graph, it should be there

[last charm]

ok what do i do now

[copper steppe]

The cast the playercontroller from there, and and then set it as a reference, then you can use it in the statemachine by getting the reference

[last charm]

how do i set it as a reference

[copper steppe]

Like you would create any other blueprint variable

[last charm]

yes but i dont know to do that either

[copper steppe]

How did you create the punch variable then?

[last charm]

ah ok

sorry

[copper steppe]

lmao

[signal hornet]

Hey guys, I have an array of meshes I'm looking to trigger an animation on the server but my problem is that I cannot specify the meshes because they depend on being 'from Persistent Level'. The only way I can specify the meshes is via the level blueprint because it can detect the meshes within the level, but I can't replicate them from there but anywhere else like a Gamemode BP or Character BP I cannot specify the level specific meshes if that makes sense. Any help much appreciated!

[last charm]

ok i just cant seem to set it as a reference, exactly how do i do it?

[copper steppe]

Drag out the pin from the "As controllername and press -> Promote to variable

That variable is your reference

[last charm]

now?

[last charm]

where did you find that variable

i cant see it anywere

[copper steppe]

You can either create one yourself, or simply:

[tawdry surge]

@signal hornet if they are placed in the level you could just make a direct reference using instance editable on the mesh array variable

[versed rune]

You also can use the node "Get player controller" and connect it to that cast

[last charm]

should it be like this?

[versed rune]

Try right click on the error and refresh

[copper steppe]

Yes, but you still need to set the reference in the event graph, you still have to exec the cast

then you can use The variable as a "get" and then get the punch in the state machine

[versed rune]

Also, cool shortcut: if you select several nodes and press "Q" you can straight them up 🙂

[last charm]

i have no more errors

but there is still a problem

[copper steppe]

What's the issue?

[last charm]

the button doesnt work

i have created a system that sets the IsPunching variable to true when you press the button and to false when you release and when the variable is set to true the animation plays

bot it doesnt work

[copper steppe]

So, if you hold down the button, nothing happens?

[last charm]

nope

[copper steppe]

Is the state machine setup correctly?

[copper steppe]

How about just starting out with just setting it to true

And you didn't by any chance switch the transitions around?

and you did put the cast into the event graph?

[willow phoenix]

try a print node on the button, if the print does not show up in console you need to enable "recive input" in the object your trying to creat this from

[versed rune]

Is in the player controller so it should receive it automatically

[last charm]

it receves the input

[versed rune]

Seems something like that

[willow phoenix]

oh sorry, i didn't notice that part

[versed rune]

How did you set up that variable Farinah?

[copper steppe]

haha

[versed rune]

oops

[last charm]

witch event graph, animBP or PlayerController

[copper steppe]

animbp

[last charm]

the IsPunching variable?

[versed rune]

Nope, the PlayerController one

In the animbp

[last charm]

i just created it

idk

[versed rune]

Yea but where are you setting it?

[last charm]

this is my event graph rn

[copper steppe]

this is still wrong

[versed rune]

Yea xD

[last charm]

i know

but i dont know how to make it not wrong

[versed rune]

In the event graph of the animbp, you need to conect that player controller cast in the node Event Blueprint Update Animation

[copper steppe]

In the animBP, go to the Event Graph,
press it

Then from BlueprintInitializeAnimation -> do the cast, and set the variable

[versed rune]

It's not better to set it in the BlueprintUpdateAnimation? it's a variable that you need to know about it everytime, idk if it will work in the initialize

[last charm]

is this the problem?

[copper steppe]

I'm doing it in the "InitializeAnimation", but I know that the stuff done there, won't change

[versed rune]

In that case you need to connect the input in the Player Controller, not the set speed, you're omitting the player controller there

[last charm]

what input

[versed rune]

Something like that

[last charm]

i dont have promote to variable, only promote Pin to variable

[versed rune]

Wait

This is how you want it

[shrewd hedge]

hey guys, I have a question, whenever I die in my game, the camera never shows my death, but instead points toward the -X axis. It'll only show my death if I died facing the -X axis

[versed rune]

And this in the transition

[last charm]

yes but is punching is a variable from player controller

[versed rune]

Nope, use "Get player controller"

[versed rune]

Instead of get owning pawn

For the player controller

[versed rune]

And don't set the player controller variable, create one on the animBP, and set that one

[last charm]

ok works

[versed rune]

I know it's confusing but you'll get the hang of it ^^

Wait, it won't work if you set the player controller variable

Or it will work but there's a better way xDD

[last charm]

it wont work if i set the is punching variable in the AnimBP because i cant toggle it with a key

[versed rune]

Create a "is punching" variable in the animBP, and then set that "is punching" animBP variable with the Player Controller "is punching", so you have that local variable there, that's the same from the controller but you just can use the variable alone and it's cleaner

[versed rune]

Like I do here

[versed rune]

And then you can just use that variable

[last charm]

like that

[versed rune]

Exactly 🙂

[versed rune]

And use that "is punching 2" there

And it should work

[last charm]

it works

yeeeee

thanks to all the people that gave me their time @copper steppe @versed rune @willow phoenix @tawdry surge

[versed rune]

You're welcome ^^

I've been there and it can be confusing as hell in the beginning but you'll end up getting the abstraction of Unreal and it will get easier, good luck 😉

[last charm]

thanks

❤️

[cyan bone]

Im having a super weird bug that scales/deforms unit (you can see the spears get bigger), when Rotating instances.
There is a clear bug, its not the static mesh that is wrong.
https://streamable.com/a9px1s
https://cdn.discordapp.com/attachments/221798862938046464/997488776328785981/unknown.png
How do i fix this problem?

I googled and it seems this is a prevalent bug, that has not been fixed. So im trying to find a work around. Pls anyone, help me.

[dawn gazelle]

Your image isn't loading properly, can post again?

[cyan bone]

Sure.

[cyan bone]

can you see it now?

[dawn gazelle]

Yes, but it doesn't appear that you're doing anything incorrect in your code. You go through a full rotation (front, left side, back, right side) and only in the left and right does it appear that the spear may be larger which makes me think that your spear mesh may be wider in one axis.

Have you tried placing a single unit on the screen at each of the rotations to see how it looks?

[gentle urchin]

Unrelated but related : only mark the render state dirty on the last index

[cyan bone]

yes

i will show you a video of the unit in different position

but not rotated by update transform

they are fine

[cyan bone]

https://streamable.com/3tamvu
As you can see the distortion only happens when i rotate the instances.
But not when rotating the actor that contains them.
Unfortunately this is not looking good. Because in most situations i need to rotate them they look super inflated.

pls help me find any work around for this. even if its something unconventional. i need to fix it

[cyan bone]

I tried that too. Didnt change much. But thank you for reminding me, its a good practice for performance

If squize doesnt know how to solve this. then we are screwed

[gentle urchin]

Havnt had a chance to look at it lol

[zealous moth]

we used to be able to spawn cascade emitters, how do we spawn niagara emitters?

[gentle urchin]

Do is it just the spears? Are you using vertex animation from a material?

[cyan bone]

yup its a VAT instanced static mesh. No its not just the spears. Its the whole soldier

[gentle urchin]

So what happens if you simply rotate an ism?

With that material?

Or

What happens to the ism without it ?

[maiden wadi]

Basically the same way. Slightly different function name. Spawn Emitter will spawn Cascade, Spawn System will spawn Niagara.

[zealous moth]

ahhhhhhhhh

ty

[cedar sparrow]

Should i put my movement logic in the player controller? or the character blueprint

[gentle urchin]

Char usually

Unless you have good reason to have it in the controller

[dry condor]

depends what kind of game you want to do, if you never intend to have anything else as a playable character it doesnt really make a difference imo

[cedar sparrow]

not really, its the same for every character and it's literally the definition of controlling them lol

ill just put in the character then

[gentle urchin]

Make a parent char then

[trim matrix]

I spawned a Character in BP with SpawnActor, but the MovementComponent does not work on the spawned Character. Why is that and how to fix it?

[tawdry surge]

Make a child class and implement the movement..
Pretty sure base characters don't have the inputs set up by default

[trim matrix]

Not sure what that means tbh. I still do not understand why it works when I put the BP into the scene, but not when it is spawned on runtime

[gentle urchin]

Auto recieve input ?

[trim matrix]

Whats that?

This is not working when the BP is being spawned.. only SetRelativeRotation works

[cyan bone]

Rotating the instances? thats what im doing?

[cyan bone]

thats a good idea to test. I will test it with small cubes to see if they also distort

but right now i was trying to solve it by adjusting the scale everytime i rotate. a bit like cheating you know

[cursive elbow]

Hi guys, I have a level in UE4.27, and I have grouped a load of static meshes together. Is there a way to turn these all into a navmesh (as well as the static mesh they are now)? Thanks!

[gentle urchin]

Right, but if you figure out why it happens in the first place, it could all be fixed properly :p

Hacks usually only last so long

Then some edge case comes along and tears it all down

[civic badge]

How would I go about scaling an actor in my map smoothly over time? I can seem to only find it for rotation

[tawdry surge]

set scale 3d

[civic badge]

that is instant

[gentle urchin]

VInterpConstant

[tawdry surge]

interp it

[gentle urchin]

For linear

Slap it in a timeline if you want curves

Or use an extra curve asset, but thats some extra work

[civic badge]

Thanks I will look into these

[cyan bone]

But it seems its a bug that happens a lot and has no fix. i googled it a lot

That is why i trying to jump in to hacks

because they all are saying there's apparently no fix

[tawdry surge]

Chivalry 2 uses vat all over the place. I remember them talking about it in a live stream, but don't remember how technical they got on it tho

[gentle urchin]

So.. its a VAT issue?

There's no issue without it ?

[cyan bone]

i had a similar issue before using just sprites

but i solved it using this:

https://forums.unrealengine.com/t/4-8-instanced-static-meshes-scaled-down-a-little-after-rotate/321579

https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/c/9/3c9dc0a047a4914825505af5de10a5dd78b78bd8.png

you see

thats so weird

yet it solved it

but its not working in my situation right now

its an issue with the rotation

it scales stuff up sometimes

[gentle urchin]

Im using ISM extensively,

never seen this

[civic badge]

So I'm having issues trying to smoothly scale this actor, this seems to only do large jumps regardless of what I set interp/delta too

Am I supposed to loop it slowly til it's the desired size?

[gentle urchin]

Interp requires tick,

or updates per frame

atleast to be smooth

[tawdry surge]

And delta should be a tiny number like .0016

Tick will provide it or you can get world delta in seconds

[dry condor]

i would do it with a timeline, but im also a noob and dont know if thats the best way to do it

[tawdry surge]

I like timelines, but then you'd just use a regular lerp node

[gentle urchin]

^

timelines gives you some out of the box flow control, curves and whatnot

which often comes in handy

[dry condor]

i wouldnt lerp it at all i dont think

just scale it up over time

[gentle urchin]

anything done in a timeline can be done on tick, but requires some extra to get it working the same way

lerp(StartScale, TargetScale)

[faint pasture]

Is it always changing or just over a defined time when something happens?

[gentle urchin]

timeline example

[zealous moth]

is there a way to check if i am overlapping an actor of a specific channel type?

other than tracing around me

[faint pasture]

Is that the only channel you care about?

[zealous moth]

yes, i am making a thing where you can phase through things like walls

i want it disabled if you are inside the wall

[spark steppe]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Collision/SphereOverlapActors/ theres this

[gentle urchin]

Or Tick example

[faint pasture]

Ok so non phasing, you block walls. Phasing, you overlap them?

[zealous moth]

yup

[dry condor]

im not sure what he wants to do, looks like on button press the scaling should happen

[zealous moth]

i think Ben pointed it out

[faint pasture]

That's a timeline

[dry condor]

thats what i said i would use for this 😄

[faint pasture]

Continually scaling driven by HP for example would be on tick.

[faint pasture]

Do you overlap anything else that you care about?

[zealous moth]

nope

[faint pasture]

You can either use end overlap to check for overlaps then switch back to non phasing

Or do a capsule trace

I would do the capsule trace on end overlap. You don't wanna be stuck phasing cuz you're overlapping a trigger volume for example.

[dry condor]

note that no overlap events are generated when you turn off collision

i learned that the hard way the other day

[faint pasture]

Well yeah, overlap is still a form of collision.

[dry condor]

yeeah well stupid me got confused by the "generate overlap events" tick box which was still set to true with no collision 😄

[faint pasture]

Either way you do the check for "Can I quit phasing now?" on end overlap.

[dry condor]

should be greyed out imo if it doesnt work anyway

[zealous moth]

against all odds i did this

works well

[civic badge]

Ah thanks everyone I have it scaling smoothly now 🙏

[dry condor]

maybe someone can enlighten me, i have this setup, when i scale the anchor (scene component) i can see both components (collision and mesh) scale appropriately. but in the game the collision doesnt actually scales up/down

[tawdry surge]

Is it's scale set to relative or absolute?

[tawdry surge]

Nah in the details of the component

[dry condor]

🤦‍♂️ its relative...

[tawdry surge]

Oh, then idk.. that should scale it with the anchor then

[dry condor]

let me try something

[tawdry surge]

You can do set actor scale or scale 3d or something

Get em all at once

[dry condor]

thanks, will try that

[dry condor]

yeah its weird, because in the viewport both are scaling

scale 3d didnt work either 😦

[winter kettle]

if I have a component on an actor blueprint, how do I make that component instance-editable?

[dry condor]

got it working by plugging in the collision directly into the transform node as a 2nd target, still weird that it doesnt work like in the viewport

[tawdry surge]

@winter kettle if you mean show up in the details panel of the level, they already do that

[winter kettle]

right, I completely missed that, thanks

[rich isle]

How to edit motion blur with blueprint?

For example changing it with key

[broken wadi]

Figure out which post process you are seeing the reference it in a blueprint (could be level blueprint, maybe character blueprint idk where your post process is) and you can drag off of it and set the motion blur float value.

[winter kettle]

I have this Call In Editor function, but I don't see the created component in the Details panel, how do I add it in a way that the component shows in the details panel in-editor

[rich isle]

It is the stock ThirdPerson gamemode

[broken wadi]

Gamemode has nothing to do with post process. A post process is something placed on your level. There’s also a global motion blur section I believe somewhere in project settings.

[tawdry surge]

@winter kettle pretty sure components created via the BP graphs just don't show up in the components or details panels

[winter kettle]

alright, thanks

[rich isle]

I know but I have an issue where regular motion blur value turns screen into mess on certain timescale, so I wanted to fix that by lowering or disabling blur on that scale

[broken wadi]

Okay so you can reference your post process which contains the motion blur and check to see if you’re on that specific timescale and adjust the float value of the motion blur accordingly.

[rich isle]

So where exactly do I find the blueprint with blur effect?

the node or something

[broken wadi]

Where is your post process? Is it part of the level? Is it attached to a character or pawn as a component?

Wait nevermind you’re a Russian supporter with “UN is useless” on your discord bio. I’m no longer interested in helping anymore.

[rich isle]

Lmao

Kinda cringe

[acoustic lava]

#animation message

Anyone know retargeting

[spark robin]

does this ring any bells for anyone? I have a blueprint using static mesh components where Im running a "boxtrace by channel - visibility" on a player pawn - the box trace detects the static mesh when spawned as an actor but not from the BP

Cant quite figure out how this could be

https://cdn.discordapp.com/emojis/984187916010020864.webp?size=48&quality=lossless

While Im here, can I get a 5th content browser somehow (other than the content drawer)?

[faint pasture]

Check collision profile on both versions

maybe one or the other is not doing the mesh default

[spark robin]

where do I find that again?

[timid rock]

Just started using ue5 for the first time
I've set up a very basic controller which literally just has this a blueprint that detects WASD input and applies a force based on that, which works fine, but for some reason my character is perpetually moving to the right even if I press nothing, like this:
https://gyazo.com/106bb744e62e05cf44406cd07fa91190.gif

[faint pasture]

Mesh editor is where you'd see the default collision profile

[faint pasture]

Is it a character or a pawn simulating physics?

[timid rock]

The character has UE5's default gravity feature on, yes

[faint pasture]

is it an actual character?

show the blueprint

also show your code surrounding the wasd -> force bit

[spark robin]

This is from the mesh editor

[timid rock]

This is it

the whole thing

[faint pasture]

You're telling it to run right continuously

[spark robin]

input axis event nodes calls every tick, the axis value is between -1 and 1 (0 if no input)

[faint pasture]

He got it, just forgot to hook the AD one up. WS is set up right

[timid rock]

ahhh im stupiddd

im very sorry

thank you for helping my blind self

[faint pasture]

Show the collision when spawned from the BP

you can just inspect it in the world

shift F1 to jump out of pawn

[faint pasture]

select the thing and look at its collision profile

[spark robin]

Can I select individual components?

[faint pasture]

I won't stop you

top right, you can see all the components inside it

[spark robin]

ooo

its a little weird, because I created several other blueprint actors like this one before that didnt end up with this issue

Idk what I did with this particular guy

[faint pasture]

ya idk. I don't see a point in spawning it at runtime, just set it up in the actor and hide it or disable it or whatever

[spark robin]

its not spawned at runtime

its just a blueprint dragged into the scene

[faint pasture]

Check its collision in the BP

[worldly oar]

hi does anyone recomend any cource or video that explains every blueprint in a way that after i could make anything i wanted

[broken wadi]

There’s a whole bunch of official courses over at https://dev.epicgames.com/community/learning?application=unreal_engine

Free

[worldly oar]

thank you

[spark robin]

Even more strange: The character actually falls through my BP if I remove the box trace

But the static mesh component on it is set to block all, how does that make any sense?

[faint pasture]

Did you check the collision settings in the BP editor?

You can override the collision settings on a static mesh in a blueprint, you probably did that

[spark robin]

You mean on like the static mesh component in the BP?

[faint pasture]

Yes

[spark robin]

No that looks normal to me oddly

[faint pasture]

but when in the world it changes?

[spark robin]

It appears to be related to the mesh

I tried adding another static mesh component with a different mesh (in the same BP), and that one collides fine.

If I then take that same static mesh component and switch the static mesh to the newer one the hit events goes away again

[wary tinsel]

hey guys, I need to set a particle system at runtime. For a sk mesh I would go with SetSkeletalMesh, what should I look for to set my particle at runtime? Thanksss

[dry condor]

i think "spawn emitter" might be what you are looking for

[wary tinsel]

mmm but I have a particle system attached to my pawn as component let's say, which is empty. On spawn I want to be able to assign it

spawn attached would give me two particles then right? (one empty)

[dry condor]

yeah i think so

you are basically spawning one, but im sure there is a way to switch the one you allready got

[wary tinsel]

yeah that's what I was looking for

should be as easy as changing a skeletal mesh, but apparently I'm missing it 🙂

[dry condor]

you can drag the particle system into the bp as a reference, im currently looking for a function to set it

node is called "set template" dragged off the particle system reference

[faint pasture]

Niagara Emitter component or soemthing like that

[dry condor]

i think hes using legacy particle system

[faint pasture]

so cascade system component or something like that

[wary tinsel]

yes cascade

guess must be this one

thanks everyone 🙂

[limber parcel]

uhh i need help integrating steam sdk into my game

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Online/Steam/

in the documentation it says to move some dll files into my engine folder

but the sdk files i downloaded dont contain any dll

[junior hedge]

This fixes my problem from a few days ago too

Was wondering why that was happening

[wary tinsel]

you should have steam by default in ue4? At least I did this with my game

[limber parcel]

then why would they tell me to do this in the documentation?

i have some steamworks files too but they are not the ones described in the documentation

im refering to this part of the doc

i checked every folder of the sdk manually now, these files simply dont exist

[trim matrix]

Hey guys! Quick question if I was trying to check distance from a zombie spawner blueprint, how exactly would I go about checking if the player is near to spawn zombie on said spawner. To be more clear, the way cod zombies has it setup, so zombies only spawn in surrounding areas. Sorry if this question was messy for yall Im still new to Unreal and im doing the best to try to explain it.

[limber parcel]

by checking the distance between the spawner location and the player location

[trim matrix]

Sounds good! Thank you!

[cyan bone]

I was told that Set Timer Event is cheaper than Timelines.
But i find myself having to create 2 events to make a proper lerp.
Is this actually cheaper? Or Timelines win in this context?

[surreal peak]

Eh... They are two different concepts

You don't really swap them out

Either you need a timeline or you need a timer

Also you are using inputs from LerpSplinePoints outside it's scope (inside LerpSplinePointsTick) which is incorrect

And the way your wires look you are doing this a bunch of times

[cyan bone]

thank you

[cyan bone]

so how could i pass arguments from a function to this event?

[cyan bone]

This is the only way i found so far. By creating 2 events. One calls the set timer, and carries the parameters, the other is the actual event timing

But please tell me what should i do instead. Because im about to do another 6 of these 😆

I mean they are working. Im just thinking if this is not the correct way and what should be the correct way.

[surreal peak]

Promote them into variables and use those

[swift kestrel]

Do blueprint macros not work with wildcard maps

[cyan bone]

But isnt it better to have less variables. That way im only using the events, and am not creating global variables

[surreal peak]

That only makes sense inside a function

It's not guaranteed that the input still has the value it had originally

BPs are c++

And c++ doesn't allow this

Function and event inputs are only valid in their scope

And in BPs the scope is the white exec line

If there is no connection between the event and wherever you use its inputs, you are doing something incorrectly

No white exec wire connection that is

And at that point you need member variables

To share the data between two functions/events

That's nothing bad, that's just how it works

[cyan bone]

ok i decided to post an image showing the whole event for better context:

you see. im using everything? nothing is going to places where its out of context.

if i understood correctly

So this was part of my effort to unclog my character blueprint. This way i dont create extra variables

[surreal peak]

Again you can't use inputs from the top event in the bottom event like this

[cyan bone]

So they should be variables

[surreal peak]

Yes

I already said that

[cyan bone]

But i can still use these two funny events?

oh well at that point then its not needed

but so far i didnt have any issues. it worked out well

[surreal peak]

I have no idea what you are doing there so no clue

Yeah but it's still wrong

[cyan bone]

this event is part of an Actor Component called Extra Functions, inside a Character. I made this Actor Component, to kind of "Export" a bunch of functions that were clogging my Character blueprint everywhere.
This particular function deals with a special attack from my soldiers, where they encircle the enemy, by moving through a spline.

[tropic pecan]

Hey there, I have an simple question. I'm attempting to make a camera setup and I do remember seeing an example on YouTube but I can't find it anymore cause I don't remember what it's called anymore. How I can describe it that it's a camera placed somewhere it follows the player smoothly but it slows down as it reaches it's limit on how far it turns to the player. The question is what is the name of that setup. I really don't remember.

It's a little bit similar to this one but has limits of how far it turns.

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

[solar sequoia]

no idea what to call it, but I could tell you that it's probably a camera actor that the view target of the controller is set to. Whether you're using one camera or multiple is a different issue, but either way you could probably drive that through your level BP, or possibly the character. Depends a little bit on your use case

and slowing the camera turn rate is a bit dependent on how your cameras exist in the context of the game, like if it's something you can check distance / rot on via the level I'd do that personally

[tropic pecan]

I'm attempting to setup a camera that rotates a little bit to an actor smoothly but now all the way. I know I found it somewhere. Just can't find it because I don't remember what it was called. I don't need instructions, just the name. If you don't know then okay. I've just been looking a lot and no luck yet so I just attempted to ask here if anybody who'd know the name. Thank you for at least answering. If I can just find it again, I'm all good.

[solar sequoia]

I couldn't even guess what to call it, but it sounds simple enough just to replicate

[hardy merlin]

Hello! I have a 2D png that I need to have hovering over a 3D actor object. How can I do that? Decal seems to require it to intersect a surface but I basically just want a floating plane.

[solar sequoia]

widget component based on a widget

[hardy merlin]

Really? Widget seems like overkill

[solar sequoia]

how else would you do it? ¯_(ツ)_/¯

[hardy merlin]

A plane?

I don't want it to billboard.

[solar sequoia]

try it I guess

[solar sequoia]

you mean appear on top or what?

[hardy merlin]

Like a signpost.

[solar sequoia]

you mean you want it to always face the player?

[hardy merlin]

I want it to not always face the player

[solar sequoia]

put it in world space then

[hardy merlin]

As a widget?

[solar sequoia]

as a widget component on that actor, yes

@tropic pecan To me it sounds like something you would design through your level BP, maybe. Have a min and max world rotation and do some vector math to make your turn rate scale down based on how close you are

I don't know your project or idea so if that doesn't work out it's understandable

[tropic pecan]

I'll find something. I did find some camera rotation limit videos. I'm just researching a last camera setup I once found that may have some answers to my Turn Based JRPG setup when selecting enemy units is all.

[solar sequoia]

You can probably make a BP that inherits from the Camera Actor and do something funky like checking when or before the rotation changes to see how much it should actually move, or something

If I have this right, the camera is stationary, and it should turn slower once the character that it normally follows is on the outer edges of a predefined area?

[tropic pecan]

I already did say I have some information like that, I was just looking for a name of something. I did appreciate your responses.

There's no need to say further unless I have another question.

[dry condor]

put some meatballs onto it and you have a great meal 😉
now i want spaghetti 😦

[tropic pecan]

Yes, I do think that's the case. I'd have to check it up again. Thank you.

[cyan bone]

there you go 🍝 al dente

[solar sequoia]

I'm still pretty bad about it, but he should definitely get that under control. Reroute, collapse, call variables multiple times if you have to. Makes it much easier to come back to without going crazy

[ocean meadow]

Hello! is this the right channel to ask a question about my inventory (drag and drop) blueprint? Thanks! ^^

[dry condor]

the organisation of the wires alone would drive me insane

[solar sequoia]

I'm bad about running wires under other nodes, or running blue wires over each other and getting completely lost when I come back to what I did

[dry condor]

yeah sometimes you cant avoid it, but multiple wires crossing multiple nodes is a nono for me 😄

[solar sequoia]

the auto curve thing that node wires do can make it pretty messy but you can almost always avoid it imo

[dry condor]

thats what reroute nodes are for

[cyan bone]

but the thing is, sometimes being all tidy when you eventually are not going to need this function.
so i think like, im just gonna do it as fast as possible, then i fix it right after. i promise. then i always forget

[solar sequoia]

I mean like how it still makes a bell shape towards the reroute pin, meaning you need even more space to fit whatever it is

[dry condor]

you need to use multiple of them ^^

[solar sequoia]

That's true. It's like envelopes in timeline editing software

[dry condor]

and yeah using more functions or interfaces cleans it up further

[long whale]

hello, when deleting actors in the level from call in editor functions, sometimes actors randomly become unloaded and fail to delete.

What's causing this issue?

[solar sequoia]

I've tried to use collapse more for single-use cases and it definitely helps

[cyan bone]

im with a dilemma right now.
I have an instanced static mesh of soldiers inside my blueprint. And sometimes this group of soldiers is attacked from 4 sides at the same time.
I have a function that deals with the lerp of turning the closer soldiers to the point of the attack of the enemy.
And it works if im attacked once by one side.
But if im attacked by 4 sides, almost at the same time. How can i make the soldiers turn to each different side at different times?
It would need something like an asenchronous function right?

[dry condor]

could you split up the group and rotate them to the nearest enemy ?

[dry condor]

yeah i saw those once somewhere, still havent used them yet

[solar sequoia]

very helpful for sweeping things under the rug haha

[cyan bone]

Ah i see. But the function that deals with turning my soldiers, would still be busy turning the soldiers attacked from the right. So how do i then make the other soldiers also turn, when the function is still busy lerping from the first attack?

I mean they are 1 instanced static mesh inside 1 BP

[solar sequoia]

I believe it would run another instance of the function

[dry condor]

thats what i mean by splitting them up

you wouldnt command the whole group to turn at once but the individual soldiers to their specific targets

[cyan bone]

From what i tested it is not doing that. Its just "overwritting"

[solar sequoia]

does the function affect all units or something?

I think it's a scope issue more than anything

[cyan bone]

No. It affects just the selected instances.

[cyan bone]

yes thats what im doing. But say you ahve 10 soldiers. You call function, and send argument Soldier 1 and Soldier 2, turn west. They are turning. But while they are turning im attacked again from another side. If i call the function to turn Soldier 6 and Soldier 7 to east, it will be messed up

[dry condor]

so your function affects all soldiers and not the individual ones

[solar sequoia]

wouldn't the function end almost immediately? I wonder if the issue is more about turning multiple units at once

by that I mean you're obviously not controlling turn rate through the function, because they don't support timelines or delays iirc

[dry condor]

yeah but if it affects all soldiers and they are attacked from multiple sides they would just spin around

[cyan bone]

It takes like 1 or 2 seconds. But if im attacked twice during those 2 seconds, it will break.

[solar sequoia]

I don't think the function runs for that entire duration

[dry condor]

are you playing an animation for that or something ?

[solar sequoia]

functions are usually faster than can be perceived, especially small ones

[cyan bone]

Its a lerp

[solar sequoia]

interpolated over what? @cyan bone

[cyan bone]

Z rotation

[solar sequoia]

what's the time element here, turn rate?

[cyan bone]

Yaw

[cyan bone]

time is set timer like 0.05

[solar sequoia]

outside of the function?

[cyan bone]

i think in c++ they would use a new thread for this. but i know nothing

[solar sequoia]

so iirc functions are designed to run as quickly as possible. Your function is not active for the entire time it takes to turn, ergo your issue is something else imo

[cyan bone]

sorry i meant an Event in the event graph

[solar sequoia]

it's probably getting called into your delay

I think you should designate your turn rate somewhere else and actually use a function for this

with the way you've described it, turn rate isn't really applicable, right? That's a controller thing

[dry condor]

you could also use a branch with a bool setting a variable "turning" when the soldiers turn, and prevent turning while they are turning but thats a bandaid

[limber parcel]

https://tenor.com/view/fixed-gif-14953349

[cyan bone]

yup its a bandaid. Because imagine my army is attacked on 5 sides. then some sides will be lagging

[solar sequoia]

remind me again, is the issue that nothing happens while the first set is turning, or is the issue that the second set overwrites the first before the first completes?

[dry condor]

yeah thats why i think you need the functions to target the individual soldiers so they can turn independently even when they are selected as a group

[limber parcel]

welcome to programming^^

[solar sequoia]

sounds like maybe he's trying to call a function but it's stopping at a delay node that's already triggered?

[limber parcel]

u cant use delays in functions

[solar sequoia]

or the same exec I mean

[solar sequoia]

correct

[cyan bone]

i have to test it more. maybe im doing something wrong

but i think maybe i would need a new actor spawned

[solar sequoia]

yeah ngl but it can be fixed

[cyan bone]

that takes care of each movement separetely?

[solar sequoia]

probably don't need it

[cyan bone]

like an actor that just moves individual soldiers

the destroy it

[solar sequoia]

why bother?

[cyan bone]

so that he is separate

[limber parcel]

why not just make an actor for every soldier?

[solar sequoia]

I think you can just instruct them from the controller or whatever this is

[solar sequoia]

yeah I also don't get why not

[cyan bone]

Because they are instance static meshes already inside one bp

[limber parcel]

are u playing this on a potato?

[dry condor]

you have an actor for every soldier allready i believe? or can you just select the whole squad ?

[cyan bone]

no i have huge squads

[limber parcel]

how huge?

[cyan bone]

goes from 200 to 3k

[solar sequoia]

like AI War 2k ships big, or like 20?

[dry condor]

ok, make a single soldier and then make a group of single soldiers to build your squad

[limber parcel]

so how many units would be involved in a battle?

[cyan bone]

im aiming at 50k

[zealous moth]

@limber parcel limit is 70 actors at once before fps is affected. If he has squads then e needs to be more efficient. In various cases efficiency is worth it.

[limber parcel]

depends if its real time or not

[zealous moth]

What he is doing is absolutely correct

[solar sequoia]

well I hope you're not using collision for each, because that's a pretty huge fps killer in some cases

[cyan bone]

im using collisions just in specific situations.

[limber parcel]

maybe it would actually be better to make ur own object type instead of actors

[zealous moth]

I would use paper 2d

:)

[dry condor]

build everything out of niagara 😄

[zealous moth]

@dry condor ooo good idea

Pass it onto gpu

[solar sequoia]

I guess part of the question should be: how individualized do you want these to be? should the group generally do the same thing (single actor / less for more), or should they all do their own thing (1:1 (laggy))?

[zealous moth]

Ue5 mesh flip book also works

[cyan bone]

i think i will just spawn an actor that takes care of movements that are differentiated in the same squad that need to be synchronous? I dont see anything else working in this situation.

[dry condor]

i have only glanced at niagara yet and it looks terrifying as a beginner tbh lol

[solar sequoia]

it's... okay. I also haven't done a lot with it, but it's all just parameters to modify a base value. More artistry than anything I think

[cyan bone]

They mostly do the same thing. Its only now that im comfronted with this problem. A squad can be attacked in some occasions by multiple units almost at the same time from different sides

[zealous moth]

@solar sequoia

[cyan bone]

If that happens then then the EVent that takes care of that, will be busy

[solar sequoia]

pretty sure the core issue is that you're using a delay in the main actor to control the rate of the individuals, right? You should use breakpoints to see what happens when your execution fails the second time

[dry condor]

the question is also how intelligent you want your soldiers to be, or if you leave it up to the player to choose attack targets

[solar sequoia]

the impression I get is that the squad is one actor that does a singular task, right? all that really varies is the number of "soldiers" in it, but that's more cosmetic and data-driven than anything

[cyan bone]

Delaying is bandaid. I can only delay so much. It will be noticeable. If i delay the left flank side for lerping and responding to an attack, because the right side is doing it, it will look fishy

[solar sequoia]

yes, the issue is that you're doing that

it sounds like it's failing the second time because your delay is active. Try to use individual turn rate or something else

[ocean meadow]

If it's okay to ask, I am currently having a problem with the dragging and dropping mechanic in my inventory. Every time I hold click to drag and drop an item into a different slot, it starts to duplicate itself that is shown below.

I am not sure if the problem consists of me having 2 slot indexes, or something might be wrong with my refresh slot function.

[cyan bone]

Oh i got it. I see. This is what i can do. C branch to see if someone is using the function. If it is, then just add the new soldiers that need to be lerped to an array, and their destinations. hm

[solar sequoia]

that sound bad imo

you might want to find a solution other than lerping it with a delay

[cyan bone]

its with a set timer

[dry condor]

im having trouble reading everything on that screenshot but the issue should be fixed by adding a do once node at the correct spot

[ocean meadow]

Thank you for responding!

I will try what you said and see if that would work!

[solar sequoia]

just send a screenshot, please

[cyan bone]

its a big mess 🍝 🍝 🐍 I will try to make a simple one that is readable and communicates the issue

[solar sequoia]

I mainly just need to see the delay/timer/timeline (you've said all 3), because that's where the issue might be

Have you used breakpoints so far?

[dawn gazelle]

From what I can see, your first Set Array Element node should likely have some kind of input for the "Item" value. Drag off from it and do a "make" and then just fill it with blank details (not sure what your structure is set up like).

Your refresh slot may also only be running on the target slot and not the slot where the drag originated from.

[ocean meadow]

Thank you for your help!

I do believe my refresh slot seems to be at fault here, because my inventory window refuses to update itself when I run over an item to pick it up with the inventory window open

[cyan bone]

So this is simplified version of what im doing

before i lerp it i push the origins and the destinations

ops no

wait

[solar sequoia]

yeah so that's probably not the issue here. Like I said, you're probably misusing your time element here, so you should send a screenshot of that

you can collapse what you sent into a function, even. Makes it a little cleaner and a bit more efficient (?)

[cyan bone]

Sorry that one was wrong

ok. you see i push the indexes of the instances im moving into ST origins and ST destinations

[solar sequoia]

so again, I don't need to see this because you know it works. Please send the section of your code that contains your timeline, timer, delay etc.

I feel the need to reiterate that you're using a time element from a single source (actor) to control individuals (static meshes). The expected issue would be much like the one you're experiencing

[foggy escarp]

Usually using brakepoints and skipping through noded by node of unfamiliar bugs is the best way to understand the issue.
Every single part should do exactly as expected. If you are unsure, make some test code do something more obvious like printing or debug strings etc.

[cyan bone]

I understand. So maybe the only way to do this is by spawning a separate actor called "Specific Soldiers Movement" that just deals with movement of each separate groups of soldiers inside my blueprint actor being attacked when needed. then destroy it

[solar sequoia]

please just send a screenshot and I can help you

[versed spruce]

Im having a hard time making a inventory system. I made one but released it cant support unique items. Like how do i give a weapon durability and keep that durability be remembered in the players inventory?

[solar sequoia]

I'm like 80% sure what the issue is, but I don't have your code so I don't know

[solar sequoia]

I believe that it would be stored on an instanced object as a variable?

[solar sequoia]

that's the way I've seen, after taking a short look

[dry condor]

iirc you can create a struct with the item information and add it to your items to hold that information

[versed spruce]

I currently have a map with a name and quantity integer. Is there a way to add additional information to the map?

[cyan bone]

ok i need to organize this. this is a mess

[versed spruce]

Referencing actors seems like a bad way to do it

[dry condor]

map can have just 2 different types inside

[solar sequoia]

that's not really what maps are for. I might not be the one to ask, but would you want a struct?

to me it sounds like you should be using instanced objects because they're heavily individualized, but I haven't done this before

[maiden wadi]

You should probably have an item. Either UObject or Struct. On it is the quantity, and the type of item it is. And you can also add a Map or Array to that of GameplayTags/Floats, which will let you put 1 to several thousand stats on a single item with no change in structure.

[halcyon frost]

I'm adding controller support but some of the UI stuff expects a mouse etc so I need help adding gamepad support to my menus Vert. slot boxs

i need to be able to scroll through the options with my keyboard/controller but right now i can only change with my mouse by clicking on the arrows

so this is what it looks like highlight using my keyboard vs hovering with my mouse, If anyones willing i can also stream it in voice chat

[versed spruce]

I have a strut for what an item does but as far as im aware a struct cant be used as a inventory list

[solar sequoia]

no, but it would be an individual item in the inventory

I think objects are a more concise way, though

[dry condor]

the inventory list itself would be an array of structs

[junior hedge]

create a input bind

you only want it to scroll if that part is selected right?

[versed spruce]

The current problem i have is i want a battery to retain it charge when i pick it up. Cant find a way to keep that info in the players inventory

[dry condor]

you store the info in the item

[maiden wadi]

You should change the brush based on focused for that widget. That'll make them look the same. For keyboard or gamepad, you simple override KeyDown events like DPadLeft, or A, or Left, and have that all run the same event as clicking the left array.

[versed spruce]

So every time a battery is created it will be a unique actor that persists in every save game? Since its a actor that keeps the battery level inside its self

[dry condor]

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

[halcyon frost]

smth like that, theres only 3 options rn so i can need to increase or decrease the value by pressing left/right

[versed spruce]

Ill check it out

[dawn gazelle]

A structure is just data. You can use a structure to indicate the contents of an inventory slot, with a variety of different values that can be stored in the structure. An inventory can be made using just an array of a structure.

[solar sequoia]

^ that's the efficient way to do it btw, then you can just iterate through your array to adjust UI stuff

[versed spruce]

my inventory system uses volume. Don't have slots. And you cant modify structs in real time so that doesnt really let me set a battery level

[junior hedge]

you could just simply create an input bind for that then in project settings then it checks what is selected and increases/decreases the value

[quartz girder]

Hey guys
pls is it possible to implement the voip system without having to using the online subsystem?
I am using a server related to gamelift

[solar sequoia]

? yes you can modify the value of structs, just not their parameters / variable types. Try breaking your struct, making it with everything including the modified value, and then setting the value of the struct

[dry condor]

look at the video i sent, it explains it pretty well imo

[versed spruce]

Wait i can modify structs in game? That was be so nice

[solar sequoia]

yeah one sec

[versed spruce]

That would make everything easier

[solar sequoia]

like that because I've made the mistake of not plugging in all break to make pins, setting everything to zero 😆

[cyan bone]

sorry for taking so long.
This one rotates all the soldiers
https://i.imgur.com/r3GrQTJ.png

[solar sequoia]

obviously replace "slatebrush" with your struct

[solar sequoia]

what does "create event" do and why are you calling it 10 times per second?

[dawn gazelle]

You can also use "Set members in <struct type>" to set values.

[cyan bone]

ops sorry

[versed spruce]

amazing, that will make everything easier. I just wanted a in game spread sheet to fill data and struts are almost that

[solar sequoia]

I never knew that. do this instead @cyan bone

[dry condor]

aaand learned something new again! thx @dawn gazelle

[cyan bone]

what a shame. i connected the loop, not the Completed

[cyan bone]

Im rotating the units 90º just that

[solar sequoia]

sorry I pinged the wrong person

[solar sequoia]

ignore the thing I just pinged you in

@versed spruce use set members instead of the thing I showed you. I guess UE really does have a solution for everything

[dawn gazelle]

Just be careful whether it's a reference to an actual struct as the input. If it's not by ref, then it won't set the value in the actual struct. Eg. If you pull a struct from an array, you need to reset the value into the array as it may be returning a copy, not a ref.

[dry condor]

this whole break/make thing takes up so much space in a BP, so much cleaner to set it directly 😄

ah ok have to get a ref then not a copy

[solar sequoia]

I had no idea that was even a thing tbh

[versed spruce]

Im gonna have to fuck around with it to learn it but this will help a lot. You are my savoir guys

[dry condor]

me neither

[solar sequoia]

structs are kinda easy once you make the first one. I use them all over, just apparently have been setting them wrong 😆

[cedar sparrow]

only the movement animations are replicating for the paragon assets. How do I get the attack animations to replicate for multiplayer

[solar sequoia]

through a replicated event, generally

[versed spruce]

Ill ive wanted was a spread sheet to keep data in. I was so excited when i found them but wasn't able to set them in real time

[cyan bone]

I wonder if i could use a struct of arrays (groups of soldiers), and then lerp them like that in that one function

[solar sequoia]

not really a solution to your issue imo

@cedar sparrow some animations are easily replicated because they're technically procedural, like if your anim BP knows to play the jump animation when a specific bool gets set, you just replicate the variable, but for event-driven stuff like attack animations, it's probably best to use a server RPC

[foggy otter]

is there any way to get accurate normalization of small vectors in blueprints? the default normalize function is kinda really inaccurate. for a vector [0, 0, 0.001] it gives me a 0 vector. if i crank up the precision it instead gives me something like [0.27, 0.69, 1.0] which is not even close to being correct, the vector drifted sideways dozens of degrees. how do i make this better?

[solar sequoia]

welcome to floating point precision lol

[cedar sparrow]

How would I do that? the attacks are just set to the InputAction binding

[solar sequoia]

so let's say 1-10, how confident are you with networking stuff? I won't explain every step if I don't need to

[foggy otter]

okay i know there is inherent limit to precision in using floats but isnt it like 7 orders of magnitude? the error here is way bigger

[cedar sparrow]

like a 3. if you want to just point me to a resource i can do some research on my own so i don't waste your time

[solar sequoia]

not to be dismissive, but I don't really know. Can you normalize just one float at a time or something?

[solar sequoia]

no big deal. Do you at least sort of understand how replication works? or what a remote procedure call is?

I'll explain whatever I need to

[foggy otter]

hm, maybe thats the way, i'll try it

[limber parcel]

you are just data

[dawn gazelle]

I've been found out.

[cedar sparrow]

So I know a little bit about replication. As in you need to enable it on certain components to make them show up in other clients. But I haven't dealt with RPCs yet

[solar sequoia]

so the idea is that a client can't just do something and expect it to replicate, because the client isn't authoritative. The server is, and whatever the server does that's designated to replicate will do so to the clients

[solar sequoia]

this is all an rpc is. You create a custom event and choose who will run it, and it will run in that configuration when that's called

[limber parcel]

and dont forget about HasAuthority node

[solar sequoia]

there's a lot to know, but let's just do this one thing first and I'll tell you what to read to learn what you need

[limber parcel]

https://tenor.com/view/wink-black-gif-19260179

[cedar sparrow]

So this should be run on server then right?

[limber parcel]

its only needed if you want to run stuff on server as a client

[solar sequoia]

that's what he needs in this case

he's right that you shouldn't always use that, but in this case it's correct

[limber parcel]

he can also use shared space with authority switch or not?

[solar sequoia]

actually, no sorry

I believe you need a multicast

[limber parcel]

for effects and stuff yes

[solar sequoia]

stick with me for the moment, but the client can't call a multicast, but the server can, so you call a server rpc into a multicast to play your montage

[limber parcel]

but on a replicated actor u basically dont need a multicast

u just have to make sure code runs in correct instanced with HasAuthority switch

[cedar sparrow]

Ok so I set the event to multicast. I need to make another event that is the server rpc that calls this event?

[limber parcel]

but for convenience u can still use run on server, multicast etc

[solar sequoia]

yeah, pretty much

[limber parcel]

thats correct if ure using listen server

[cedar sparrow]

which i am

[limber parcel]

if you use dedicated server u dont want this to run on the server

[cedar sparrow]

makes sense. luckily its listen only for me 😄

[limber parcel]

yeah listen server are easier to manage i guess

[cedar sparrow]

so what does that look like? a normal function or does it need a replication setting too

[limber parcel]

it looks ok

but wait

im not sure if the montage needs to be called on server or client

[solar sequoia]

multicast

[limber parcel]

technically it should be replicated though

[solar sequoia]

something like that

@cedar sparrow

this case is a little weird. Normally it's just something the server needs to do, so you server rpc, or maybe an owning client once in a while

#multiplayer message

[cedar sparrow]

oh hey this worked

[solar sequoia]

I suggest you read the whole thing, maybe skipping C++ stuff if you haven't done it, and just reference that whenever you need to. Specifically the graph that shows what actors are replicated, from the Game Instance down to the pawn

[solar sequoia]

👍 like I said, it's fairly easy. You just have to be used to doing everything kinda roundabout to make sure it runs where it should

[cedar sparrow]

Ill get to reading. thanks!

[minor lynx]

I am trying to use ConvertMouseLocationToWorldSpace but it seems like its returning the location of my camera not the mouse or something

err not exactly, it follows the mouse but its all the way up against the screen if you will. instead of on the ground/terrain/object my mouse is hovering

[astral stratus]

how can i smooth a lookat roation? I have it so my AI looks at me and shoots

its very snappy right now

[icy dragon]

RInterp To

[astral stratus]

thanks!

might be doing something wrong forgive me still learning
https://gyazo.com/ff628395a07f0a3a234633b4cdaeb371

[tight schooner]

@astral stratus the interp is designed to change things a little on each frame so that it's a smooth animation that happens over time. It has to be done on Event Tick. (And you need to give it the delta time or World Delta Seconds.)

[astral stratus]

i thought converting delta time to a variable and setting it on the tick would work

[tight schooner]

Get World Delta Seconds node will give that to you. No reason to store it into a variable

[astral stratus]

ahhh thats right

[tight schooner]

But in any case the interp needs to happen every frame, so the rotation has to happen on tick

[astral stratus]

ok

[tight schooner]

You can control the ticking with Set Actor Tick Enabled node if you need to conditionally turn it on/off

BTW you don't need to cast to your character class to Get Actor Location

It'll work without the cast

Unless you're checking something idk

[astral stratus]

sec

https://gyazo.com/8f23925480f901430c369857c5d9278b

still learning so i might have something wrong

[tight schooner]

Hard to say but you need to put Event Tick on your event graph, and move the Set Actor Rotation there

[astral stratus]

so put the tick in and just plug it into the set actor rotation?>

[tight schooner]

Probably. I can't see your whole graph so I can only guess what you need to do

Event Tick is an event that executes once per frame

And delta seconds is the frame time

[astral stratus]

it works but i now have an error

https://gyazo.com/a6c4fe24039fcca46bc200df1e69a40b

[tight schooner]

"Accessed None"? Show me what you got

On your graph

[astral stratus]

ok

[tight schooner]

Accessed None means it's trying to get invalid data

[astral stratus]

ill show you the whole thing gonna take 2 screen shots though

[tight schooner]

Go for it

[astral stratus]

actually i got a better idea one sec

https://blueprintue.com/blueprint/ef7nue3y/

[trim matrix]

Guys what will be the performance difference with making with complete blueprint or with C++
When making a open world game something like a small town of 4*4 km

[fiery swallow]

depends?

[tight schooner]

@astral stratus your scenario is actually pretty tricky cuz you want to do a series of actions. It might even be easier to do it with a Timeline component, where the turret turns toward the player during the timeline and then shoots on complete.

[astral stratus]

Ah back to timlines lmao

[tight schooner]

but the path of least resistance given what's on your graph could be...

replace the target for the 2nd Get Actor Location node with Get Player Pawn, lol

[trim matrix]

Any rough estimate

[tight schooner]

or well, then the turret will always look at the player no matter what. Hmm...

I guess start with actor tick disabled. Then when the OnSeePawn event fires, enable actor tick.

(Class Defaults panel has the option to disable actor tick by default)

[astral stratus]

ok

[tight schooner]

Then the SetActorRotation stuff will only happen after OnSeePawn is called

and if you have an event that detects when the pawn goes back to unseen, you can have it disable actor tick

and the turret rotation will halt

[astral stratus]

havnt gotten that part done yet but thank you

[drifting peak]

does anyone know why this doesnt remove index?

[faint pasture]

Make your item definition include some info that could be used for the battery level, if items as structs is what you're doing

[gentle urchin]

You dont need to get the element ?

Simply remive the randomly found index

Remove*

[faint pasture]

Structs are mega cheap, you can have a field like
float Condition
or
float CustomFloat

to represent level for a battery, something else for seomthign else, etc

[drifting peak]

@gentle urchin i tried to remove that as well

[faint pasture]

I have arrays of custom ints, floats, and vectors for my struct representing a saved and customized vehicle part.

BTW how does a struct with an array in it get serialized?

cuz you don't know the array's size in bytes

[gentle urchin]

Sure it finds an index?

Also if this array is an input of the function you need to input it by ref

[drifting peak]

@gentle urchin it returned true every loop

[gentle urchin]

Well now you've added to it

Before the check

It might still be true, but atleast your test doesnt prove it..

[faint pasture]

What are you trying to do?

[gentle urchin]

Atleast not by what im seeing

[faint pasture]

Also what is the scope of this array, is it a local variable?

How do you know it's not removing?

[drifting peak]

how would you suggest I test to prove it

@faint pasture its not local var, i know its not removing because the number is repeated after being removed

trying to make a dice roll

[faint pasture]

Why would this be how you do a dice roll

[drifting peak]

but each index cant be repeated

@faint pasture how would you suggest to do it then?

[faint pasture]

Random int from 1 to 6 lol

[drifting peak]

..

I need to store the all sides of the dice

and the number has to add to 21

random int from 1 to 6 wont work lol

[faint pasture]

What's the use case? Are you doing something where anything beyond the face-up number matters?

Like is this physical dice?

[drifting peak]

yeah it will be a physical object

[faint pasture]

WHy not just let physics do the work for you?

do you want the number before doing the animation/physics or after?

[drifting peak]

you are saying to have a dice and let it roll with physics right

[faint pasture]

I mean a random int from 1 to 6 is good enough for most games, I'm trying to nail down exactly what you need here

[gentle urchin]

^

[drifting peak]

in this case, each side of the dice, will affect each side of a wall, the number will affect the walls ( such as dynamically changing the walls with different numbers)

thats why i have to store the value of each side

[faint pasture]

so it's more than just the face up number

[drifting peak]

I would say so

[gentle urchin]

Sounds like anything but face down

😅

[faint pasture]

so you need one of the 24 orientations it could land in

[gentle urchin]

Why 21?

[drifting peak]

@gentle urchin because all sides add to 21

and the numbers cant be repeated

[faint pasture]

do you care if they're in canonical order?

like the 1 and 6 opposite?

or just that they don't repeat

[drifting peak]

canonical order doesnt matter

just no repeat

[faint pasture]

k then make an array from 1 to 6 and call shuffle array on it

[drifting peak]

aight ill try it

[faint pasture]

you'll have a jumbled up array with all 6 numbers in it

then just call indices 0,1,2,3,4,5 your top,right,front,left,back,bottom or whatever

if it MUST be accurate to real dice you can just roll a number from 1 to 24 and have that be one of the 24 orientations a dice could have

[drifting peak]

I am currently already doing that

[faint pasture]

It looks like you're trying to reimplment shuffle array on your own

it's a node

just call it

[gentle urchin]

^ sounds like a neat solution

[drifting peak]

you know what

[faint pasture]

Now I'm interested in randomly rolling the orientation preserving the actual orientation of dice

with the numbers oposite

[drifting peak]

thats pretty good solution

but yeah i might also want to preserve orientation for the fun of it

[gentle urchin]

Also, not an issue anymore,

[drifting peak]

your solution works i just did it

[gentle urchin]

But one of the reasons your function repeats

Is that you're pulling from a random

A random is random or every call

So when you get it the first time, some number is added from index X. Then you remove some index Y

You must save the valurs of random if you wish for them to persist

[drifting peak]

i checked that the random stays the same until the next loop

[faint pasture]

I would honestly recommend that because it might look weird to have a 1 next to a 6 instead of opposite, and it would also allow for some patterns

[drifting peak]

im sure you are making a point @gentle urchin I might just not be following

[faint pasture]

although it constrains your random generation space down to 24 options instead of uh 6^6?

nvm it'd be 6!

720

[gentle urchin]

If you checked by the same method as your isValid, then its a false positive

[drifting peak]

@gentle urchin how do I check it properly?

[tight schooner]

Every time you connect a "pure" function (a node without exec pins) to an executed function/event (a node with exec pins), the "pure" functions are called again. So if you connect a "Random..." node to two executed nodes, it'll roll two different random numbers. The "Random" node doesn't remember the last thing it rolled. That's what's going on in the screenshot you posted JFYI

[tall rain]

Hello, I mostly prototype little games for fun, but I find myself repeatedly creating the same classes and actor components (Health System, Experience System, AmmoSystem, etc...). Do yall create like a "core library" of modular components you use often? What would be the best way of doing this (in terms of making them accessible through different projects and updating them) (Also sorry if I'm interrupting, I don't know discord etiquette and if its cool to add another conversation)

[drifting peak]

@faint pasture @gentle urchin @tight schooner thank you yall for helping, I appreciate it, have a goodnight mates

[gentle urchin]

The only safe way is to save it in a variable untill you are done

[faint pasture]

Plugins

[tight schooner]

@tall rain re: interrupting... it's par for the course in this channel. Don't worry about it

[faint pasture]

I have a project that's just a container for plugins I've made for various systems. Just drag and drop them and you're good to go

[gentle urchin]

But then you always have to go back and update the core

Which is fine if you're structured

But for me thats troublesome 🤣

I want some autosynced plugin that i can edit on the fly in any project :p

[faint pasture]

Automagically linking them together across different projects will take some source control or symbolic link magic but it's doable I'm sure.

Not worth the trouble for me, I just dev in context then update the Plugins project with the latest whenever I want

[gentle urchin]

Perhaps engine plugin solves it ? Not sure if you can edit them "randomly"?

[faint pasture]

Ya engine plugin would but then your team members aren't getting them and it's not nice and contained in the project

[gentle urchin]

Honestly im just making it to be an issue. Its less of an issue than i want it to be

[faint pasture]

Not too much trouble to manually update unless you're changing projects 5x a day.

[gentle urchin]

Yee fair

Usually stick with a project for some months

[faint pasture]

I have like 5 that are multiple years old

the joys of part timing this stuff

[gentle urchin]

Oldest project i got atm is from 4.14

Rest is history as they say

[tall rain]

I'm pretty beginner so I've been creating a ton of new projects. The plugin idea seems like the way to go if its easy to update. can I update the plugin form inside multiple projects? I know I would have to update them in every project though but im likely not going back to projects cause theyre mostly just to have fun while learning UE

[faint pasture]

My oldest is from 4.1 lol

It's been upgraded all the way up to 5

I bet it has some cruft in it

[gentle urchin]

Holy shiet 😅

Is it released yet? 😂

[faint pasture]

I havn't done any real work on it for a few years, just keep it up to latest engine and make sure it compiles. I decided that a multiplayer only action game is a bad idea for a small outfit.

[gentle urchin]

Exactly, old learning projects

[faint pasture]

The design was basically Arathi Basin with 3rd person RPG action combat. Way too ambitious.

[gentle urchin]

As most early projects are

Like

I have a project named mmorpg

Who am i fooling 🤣

Me and what army

[tight schooner]

Apparently my oldest is UE4.12 (2016)... a 2-man project that was going to be a DayZ-esque multiplayer game with little or no graphics; just 3D sound and VOIP with grid-based movement in a pitch-black dungeon. It was as much the nebulous game design that killed it as the tech requirements. We didn't have a strong idea of where to take it.

But at least I got my feet wet with blueprinting

[gentle urchin]

Thats usually my struggle aswell, and is why i abandoned my last project

Not having a clear idea of what the end result is

And I get influenced by input i asked for, but ignorantly starts to implement parts of it before i realize i'm drifting to far from the original idea, losing motivation :p

[faint pasture]

Yeah I looked it up, April 2014 is when I started on my oldest project lol

man they moved fast if 4.12 was only 2 years later

[gentle urchin]

Time goes by to fast

I need more time for my projects

Guess i cant have more, so only solution is to clone myself

That or hiring 😮‍💨

[faint pasture]

Couldn't find my first video but this is the oldest video of my first project I could find.

"sure, a pvp game for your first project while you're learning how to program and also learning blender is a great idea"

[gentle urchin]

It's a start, as you say in the video! Well done while learning!

[faint pasture]

"Back in the day we didnt have no dang tootorials" old man noises

[gentle urchin]

xD

[drifting peak]

multiplayer for first project thats hardcore mate

heli giraffe

[gentle urchin]

What in the world

girafocopter

[faint pasture]

I'm still multiplayer but at least it's not a dedicated server competitive 20v20 action RPG game lol

[drifting peak]

LOL true dat

[naive geyser]

Hi, i have set up an axis mapping for mouse X. However i always have to hold down the mouse button for it to work, else it doesnt work if i swipe the cursor across the screen. How do i make it work without holding down the mouse button?

[faint pasture]

Set Input Mode

[naive geyser]

In the actor?

[fleet cedar]

Hello. If I had a big event like... 'Disable all locked doors' that affected multiple blueprints where would I put that event?

I get confused by the game mode / player controller,

[pale blade]

Hm, maybe something like a manager? Interaction manager that handles all interactions?

[gentle urchin]

Global bus?

Basically a dispatcher that can reach any blueprint ?

[foggy escarp]

Use action mapping or a branch to check for value.

, oh nvm discord failed to properly update

[trail sierra]

Is there a better channel for an absolute newbie to ask blueprint questions?

[limber parcel]

no, but u should watch some tutorials before u ask stuff like "how do i make multiplayer"

[trail sierra]

No I was going to ask a question about a step in this tutorial im going through that I didnt understand

[limber parcel]

wel then what are u waiting for xD

[trail sierra]

It was just a basic tutorial on adding movement input to a pawn, ill link the actual tutorial then ask question

https://www.raywenderlich.com/663-unreal-engine-4-blueprints-tutorial

I understood all the steps for taking the player input, scaling to a max speed then combining all those together. I thought that would lead to movement, but then the tutorial had me add this section

and I dont really understand its purpose

[still rain]

can i get any point info of spline mesh component?

like how many points a spline mesh componet have or anything like that?

[tight schooner]

AFAIK a single spline mesh component only has a start and end point

here are the nodes available for spline mesh components

Spline components (no mesh) can have multiple points

but if you want to cover a spline component with spline mesh components, you have to spawn several of the latter AFAIK

[safe iron]

Hello there
The add node does not work :/
I am trying to add an actor to the array but when I check that array it's empty for reasons
That's about it... I should mention that this array right here is in a struct, which then is contained in an array of structs itself, since I needed something similar to an array of arrays but had no other way to do that
But I think it should work anyways

[naive geyser]

I am using axis rn, I’ll try using action in a bit

[still rain]

but in ue4, if you drop a spline mesh actor in the scene, it will have at least 2 points

[tight schooner]

start point + end point = 2 points

[still rain]

iirc, we can edit it, like add more points?

but i have no idea why i cannot do this now

[limber parcel]

i havent seen it before but im guessing it reduces the movement speed, something like drag

[trail sierra]

Is there a quick way to temporarily "comment out" blueprints?

so I can take them out of the equation without fully deleting them

[tight schooner]

yeah sorry idk much about spline mesh actors. I know about spline mesh components. I'm looking at the actor now; as far as I can tell it contains a single spline mesh component. Not sure what else is possible with it.@still rain

There are some tutorials online that detail how to loop through a spline component and systematically attach spline mesh components all along the spline component. I'm sure if you google you can find one

@trail sierra Right click on node and "do not compile"

might need to tick an editor option to show that

[still rain]

it's just splineMeshComponent with an actor

[tight schooner]

@trail sierra in UE4.26 anyway, to enable the commenting-out of nodes, go to Editor Preferences --> Content Editors: Blueprint Editor --> Experimental section

click the chevron to reveal more

Allow Explicit Impure Node Disabling

[still rain]

I knew how to do it with spline component...but since the asset i get is a bunch of spline mesh actors...
