blueprint

[woven wing]

That's how I did it. I thought it was an interesting little problem.

https://blueprintue.com/blueprint/au_xckl4/

[river ember]

I am getting a wall of LogNavigationDirtyArea: Warning: Skipping dirty area creation because if empty bounds - any idea what this means?

[woven wing]

Blueprint is very mucky about doing some things.

The function "ClosestToTarget" just does what it says on the tin.

This is not the fastest it could be, as it does test the distance twice.

Caching the distances and storing them would avoid some extra math.

[opaque valley]

Really dumb question. How does this look in code? I don't understand how the output of a set function is then used as the input to another function. Is this just the same as storing the last known value of that variable and using it as the input?

[woven wing]

That 'Interp Offsets' there isn't a function. That's a Macro.

[opaque valley]

Ok, but a macro is not similar to a function? It's doing work with an input from the output of a set action and then somehow returning something that will then be the input of the set.

[woven wing]

So... it won't work actually.

A macro doesn't do work.

[opaque valley]

It seems to work fine

I just don't understand it

[woven wing]

You're calling this every frame?

[opaque valley]

On the anim tick

[woven wing]

OK, so what's happening is, the macro result from the previous frame is getting left in the buffer and is then getting picked up with the evaluation thread gets to the Set function.

Or, no - the opposite.

[opaque valley]

Ok, so then my assumption is correct. Old value basically.

[woven wing]

Yeah.

I wouldn't leave it like this.

I'd use a Get for the input to Current.

[opaque valley]

I don't use BP, I am interpreting some to change it to C++

So I needed to understand what it's doing to convert

[quiet kettle]

Thx 😄

[cold raft]

I must be missing something simple here - how can I get a reference to the skeletal mesh equipt in the players main hand (I want to attach a cable component to the end of a fishing line)

The function below attaches to hand, and the print sockets underneath correctly find the sockets on the fishing rod (labelled tip and tipSocket)

[woven wing]

You can find a mesh attached to a particular socket like this:

But you should just store a value in a variable when you assign it.

[rough wing]

@woven wing I'm making some kind of logic error, could you take a look if I send you the blueprint?

[woven wing]

Sure, paste it into the pastebin and I'll take a look.

[rough wing]

https://blueprintue.com/blueprint/mzoaa7s3/

[woven wing]

Uhh.

Well this is much more complicated then you suggested.

What's with the sphere tracing?

[rough wing]

The problem is probably in the loop body

That gets the world objects

And I want to get the closest 2 objects

the multi sphere trace is what finds the objects

[cold raft]

Thanks @woven wing - I may be asking the wrong question then, I can see the mesh names and socket names, but cant attach them to the cable component. I cant work out how to attach the cable component to a skeletal mesh that hasnt been spawned as an actor

[woven wing]

Hmm

[woven wing]

That I'm afraid I don't know much about. I've never worked with cables.

[cold raft]

Cheers anyway!

[rough wing]

Ah I think I found it

[woven wing]

Cool. I was going to say, it looks like it should work fine.

So I would have had to go in and step through with the debugger.

Which, if you don't know how to use it, is worth learning.

[rough wing]

Are you talking about breakpoints?

[woven wing]

Yup

[rough wing]

Ah alright, thank you!

[hollow cape]

@cold raft worth checking out the VICO cable plugin. It's not cheap, but I've been able to do some pretty crazy stuff with it

[cold raft]

Cheers @hollow cape , I will have a look

[stuck hedge]

Anyone done a control remapping system before? I built one, which works flawless in editor. Controls are saved, remapped, etc. but in the shipping build it doesn't work. Remap a key and restart and it can't seem to read it anymore.

basically when a key is remapped, it removes the old map, applies the new map, then updates a struct in the game instance which holds the default key and the new mapped key. When the menu is built it reads that struct array, extracts the keys and creates cards on the UMG for players to see and remap. Works perfect in editor.

just click the button, press your key to reset.

if I do that and restart the editor the new key bindings are listed there. In a built game the entries just disappear.

in the shipping build after reconfiguring up and down and restarting I get this

[slate cipher]

anyone know whats going on here ? https://streamable.com/q42n9b

[olive sedge]

@slate cipher your camera maybe stuck in an actor or something? Try moving it just to make sure it's not

[tough raptor]

Hellooo people gm
I want to make a sword trail from its collision through the mesh, what do I need to do in order to get hit resoults every tick, instead of only on overlap begin and end only?

[olive sedge]

also: anyone else having trouble loading the marketplace?

@tough raptor you can set a boolean to true on overlap begin and to false on end

and check for that in tick

[tough raptor]

But then the hits should somehow be asked from a lientrace or something??
Because the event is not going to yield anything

[olive sedge]

@tough raptor I'm really having trouble parsing your questions.. Be more precise or it will be hard to help you

[tough raptor]

So what event or method should I use to get hit or sweep resoults from my sword with the other mesh every tick it is overlapping?

[olive sedge]

Disclaimer: I'm pretty new to this so take it with a grain of salt but yes, I think I would try a line trace first

either from sword hilt to tip or from the entry point of the mesh through the character with the rotation it has

not sure if you'd even need a trace though. You just want to have a visual indicator that the sword ran from x to y?

[tough raptor]

Yes, I want to use those points to build a wound, but I thought the linetrace solution was too much, shouldnt somehow overlapping be also able to give information every frame??

[olive sedge]

Not sure, maybe try OnComponentHit?

doesn't that trigger every frame?

[slate cipher]

I’m modding a game and I don’t even have access to the player camera so I don’t think that is it rip thank you for the suggestion though

[trim matrix]

Previously in this menu was create new c ++ class, but now it is not. (ue4.26

in blueprint project

[somber quail]

hey i cant save my map build data
The following assets failed to save correctly:
/Game/Maps/Map_BuiltData

[odd ember]

maps generation is depending on context. the parameters become what you want to do with the maps and what the objectives of the game are

[maiden wadi]

@trim matrix Use the one on the File menu at the top left. They removed that in 4.26 for some reason. But then there's quite a few list issues with 4.26 from what I've seen. Might have just been a mistake, might have been intentional. 🤷‍♂️

[solemn parcel]

Hey, I got two questions for this BP :

1/ I've tried decreasing overtime the effect of Add Force with the red circled stuff. But it doesn't work. Why ?

2/ My branch is connected to a condition linked to a On Hit Event. Does the Tick Event is calculated all the time or only when the value of the Branch is true ?

[cold raft]

@solemn parcel - for /1 - are you getting the updated magnus force before setting it (not sure it your BP is doing that)

[solemn parcel]

@cold raft The Magnus Effect is Set as a variable before applying the force

[cold raft]

/2 - event tick runs all the time, but your code only runs if condition is true

[solemn parcel]

2/ If the code condition is false, the it makes the tick event less expensive ?

Branch condition*

[cold raft]

I would hope so! I have code like that too (happy to be corrected)

[solemn parcel]

1/didn't get what you meant I think =p

[dawn gazelle]

Delta seconds is typically only 0.01 on every tick, unless you have the tick rate higher.

So it's not subtracting much.

[solemn parcel]

I already tried upgrading the multiplicated float value to insane numbers, but the Force Added just gets crazy strong, and does not actually reduce it to zero

[dawn gazelle]

What does your magnus effect output on print string?

oh wait a second, you're trying to decrease a force by adding more force...

[solemn parcel]

@dawn gazelle A print string replacing the add force ? Seem to show the correct vectors each tick

[dawn gazelle]

Does it show a steady decrease?

[solemn parcel]

Seems like it actually switch onto negatives/positives/negatives/postivies quite a lot

I'll try clamping it

I didnt clamped still but using the print string on the original Set Magnus Effect seems not to change nothing about the vectors switching negative/positive. But this effect works as desired

Now Im interested to know why you said that im 'trying to decrease a force by adding more force' ? Could be something i missed

[trim matrix]

oh i found it. thank you so much

[maiden wadi]

@solemn parcel Are you after the effect of like a curved baseball throw?

[weak kindle]

mic input is so hard to undeastand it can someone explain how to works l want only get the sound volume from player but l cant get it 😦

[solemn parcel]

@maiden wadi Yeah. I got the effect working with that script. But i'm trying to get the effect decreasing over time first.

In a perfect world I'd like to make the effect 'stop' under a certain treshold of the ball slower rotation velocity*

[tight schooner]

If it's a transient effect then you can try a timeline... It's like a tick event that lasts for a predefined amount of time, and it also samples a custom curve... so it can e.g. output a float that goes from 1 to 0 over time

Otherwise you have to record the start time (Get Time Seconds node) into a variable and have some math that scales a thing based on how much time has passed

You can also control tick on/off with the node, Set Actor Tick Enable

so you can have your tick event check if some condition is reached and if so, stop ticking

I'm not super clear on what you're trying to do, but hopefully one of those loose ideas helps

You can also change your tick interval to a fixed time (e.g. every 0.2 seconds) or create a looping timer event (Set Timer By Event node) if you don't want to deal with the Delta Seconds complexity.

[gray quarry]

Can anyone help me with this? The character is spawning but it's not possessing. Have tried every combination possible. Thanks!

[gritty elm]

is this NPC or your main character?

[gray quarry]

My main character, it's for multiplayer

[gritty elm]

first try to replace new pc variable with get player controller

also you may need to spawn default player controller

and last thing to do make sure change this option in your main character settings : @gray quarry

[gray quarry]

Thanks! Will try

[muted dawn]

is this ok to have?

actual body is the body everyone can see

im asking if this will cause performance issues

[solemn parcel]

@tight schooner Yeah this actually helps a lot. I'll try the timeline first, seems to fit. But even if I use the control tick On/Off, is there a way to decrease the amout of Add Force over a set (short) time after the Off tick ? If it's clear

[maiden wadi]

@solemn parcel Having some pretty good results with this.

[heady rain]

hey guys, does anyone know if it is possible to use actor foliage in procedural foliage volume ?

i'm hitting resimulate but it doesnt place anything. i tested with regular static foliage and in that case it works. but i want to procuderally generate actor foliage, basically each tree has blueprint code.

i am able to use the actor foliage i made with foliage mode but i am wondering if there is a way to use this actor foliage in procuderal generation volume

[solemn parcel]

@maiden wadi You using the Branch to stop the 'effect' if it doesn't meet the velocity condition or the angular velocity condition ?

[maiden wadi]

More or less. If it's not spinning fast enough or moving fast enough. You could optimize it for gameplay by setting tick off if the object stops moving, and turn it on again if the object is hit, which would cause it to start moving again.

[solemn parcel]

this should do the trick

this would stop the 'effect' which is what i'm searching for. Is there a way to make the 'effect' decreasing to zero after the condition isn't met by using a timeline ?

@maiden wadi Thanks tho, it works like a charm right now 🙂

[sly sand]

how I can make bp that " If health run to zero this widget appear"

I have no idea to link it

[dawn gazelle]

How are you normally detecting damage?

[sly sand]

detect damage?

sorry i not understand

you mean damage object blueprint?

[dawn gazelle]

How are you getting your player's health down to 0 in the first place?

What event is firing that gets it to 0.

[sly sand]

this event

[open crypt]

Can anyone explain to me why when picking a row structure for a new data table, all my structures appear twice? (and when I hover over one to see the path, these appear to be identical)

[woven wing]

My guess is that you've copied and pasted them somehow.

'Cause You have one item that isn't duplicated.

IC_FScenario_2

So it's not a UI error.

[open crypt]

yeah i just saw that

when in doubt, assume operator error

but here's where I'm confused

my content browser, that structure appears twice but there's only one

[woven wing]

So, as you're handling your health system yourself, you probably want to put in a check for 'Hey, did my health drop to zero? If so - I'm dead.'

And if you do detect that you're dead, it's probably a good idea to emit an "I've died!" event.

From an Event Dispatcher.

Because usually a bunch of stuff happens when you die.

So it's handy to have one thing to hook your particles, game mode changes, and animations onto.

[open crypt]

@glad cloak Can you advise if there's anyway to reliably modify the structure a data table is based on so those data tables can be refreshed/updated? I've seen posts involving shutting down the error and saving the structure but not the data table but I'm looking for a more documented process

[woven wing]

I don't think there is one. I suggested that you export it to Json.

[sly sand]

@woven wing thanks but, can i get an example of blueprint , please?

[woven wing]

Nope.

[open crypt]

Yeah, If I had more than 20 entries I would

[sly sand]

I'm just try unreal for 2 days

idk about event dispatcher

[woven wing]

Google is useful.

[open crypt]

Watch the livestreams

@sly sand as someone who has made this mistake so many times, you want to watch those livestreams, particularly the ones about blueprint communications they will save you sooooo much time and frustration

moreover, they make it so much easier to get help because you ask people more qualified questions, and they are much more willing to help when you showed them that you've taken logical steps to solving a problem but could use just a nudge - nudging someone in the right direction takes little effort - most people don't want to have to do heavy lifting to explain something to you

[open crypt]

but I know exporting to json is going to have issues for me, just things I've learned that they take more time than you think they should or something unexpected complicates the process - but I'm adding the notes to my data table for if we get an excessive number of entries, we will use that for exporting/reimporting

[dawn gazelle]

You'll want to use the "apply damage" node where you're doing your health drain thing on the screenshot you sent me.

[sly sand]

thanksful very muchh I'll try like you say 👀 👌

[sly sand]

OK i'll sent to your dm

[fervent swallow]

hello! I've discovered that when a trigger box contains inside some interactuable stuff, that interactiables thing breaks. Lets say I have abox that can be moved by the player. if I have a triggerbox that just happens to be there (it doesnt have to be anything related with the box) it happens that the player just cant muve the box at all. It happens in more place, but we've been trying to avoid it so far, but now we need that trigger box there. Does anyone know how to solve this issue?

[open crypt]

When you say "contains" what do you mean? is the interactable cube attached to that triggerbox in any way?

[fervent swallow]

no. I actually menat that the collide somehow

[open crypt]

What could be happening, depending on how you setup your interactions/input, is that the triggerbox is taking the input event"

well then you need to check your collision channels

if that interactable cubes will never have anything to do with the triggerbox, you can set them to a different collision channel

[fervent swallow]

are you talking about this?

[open crypt]

yep

but if you aren't familiar, for the love of God, watch a video on it. TWICE

it's one of those things that can be simple but if you don't understand how it works, really, really frustrating, because you will not get an error or explanation, it simply won't work

[fervent swallow]

I am familiar with other kinds of collision tables

[maiden wadi]

@fervent swallow How does your intractable stuff work? Line traces, or?

[open crypt]

and later you can get into trouble because you forgot about a collision channel and now it's screwing something else than you didn't turn it off for

[fervent swallow]

some of them are other trigger boxes, and some of them are something else, I dont know haha I haven't done the other ones

[maiden wadi]

So to recap quickly. You have an "Interactable" inside of a trigger box. And this doesn't work in this case. But if you moved the trigger box, the interactable would work?

[fervent swallow]

yes

[maiden wadi]

We need to see how you're doing the interactions then. Likely a logical issue.

[fervent swallow]

I feel like it is an issue like the one Blakestr described right?

but is there a way to add more object types than the ones that already exist?

[open crypt]

go with what Authaer suggested

[dawn gazelle]

In Project Settings

[maiden wadi]

Not likely. That's usually for blocking line traces or something. You're using overlaps. If your trigger was blocking a line trace for interaction, that's where you'd look and disable the channel that's blocking the line trace. So unless your interaction logic is running on a line trace on the "Light" collision channel, it's most likely a logical issue.

[open crypt]

The logic is probably the issue, unless you are doing a linetrace and taking certain collision, but you would have already known that

exactly

[fervent swallow]

oh I see

[fervent swallow]

thanks! that is good to know

[open crypt]

Example if your logic takes the user's mouse when they hover over the trigger box, then they won't be able to hover over the interactable cube

[trim matrix]

hey may i ask for some help here? i know its a multiplayer issue but people in there are talking to each other and all so i figured id try here

[fervent swallow]

but then why does the probelm only happen when stuff collides with the trigger boxes? @open crypt @maiden wadi

[open crypt]

because the collision is triggering your overlap - if you have a problem with the logic implemented with your overlap

basically collision is your trigger - but if the event that GETS triggered is flawed....

[maiden wadi]

@trim matrix What's the question? Usually just ask, people will usually answer when they can.

[trim matrix]

well i posted the question on the UE forum, ill link it so its all there without having toexplain it again

https://answers.unrealengine.com/questions/1001818/view.html

[open crypt]

@woven wing Super confusing - rather than mess around with trying to refresh an existing table - I made a brand new structure, - then I made a new data table based on that structure - but this Image variable (which is the one thing I wanted to add) won't show up in the data table as something I can edit)

it's set to editable too

[woven wing]

What class is the image?

[open crypt]

yeah I'm figuring that out - must not be the correct one

just tried a simple structure of a few images and made a data table - same issue

[woven wing]

Right, I think if you used 'Image' - that's actually a widget.

[open crypt]

wow, I thought this whole issue was the nature of data tables but apparently it has to do with an obscure fact about data tables not liking certain image classes?

[woven wing]

If you want a texture, it's something else.

[open crypt]

is that because an image isn't completely static?

[woven wing]

It's a widget:

[dawn gazelle]

Texture2D is probably what you want?

[woven wing]

Yeah.

[willow phoenix]

is there a way that allows me to assign an "additional" material to any mesh so i can use for example an outline-material on this mesh? i don't know if that has a specific name i could look up

[open crypt]

those tricky bastards - thanks guys

[maiden wadi]

@trim matrix First off, that is not replication. What you're doing is using RPCs. Replication is setting a replicated value on the server and letting the replication system update clients for the new value. This is an important distinction even if sort of small. The reason for this is that replication state persists. If a client DCs and reconnects, everything that was RPCed before won't happen again, where as anything that is replicated from server will be reupdated for that client after they rejoin. Also, you're running stuff on Beginplay in the level blueprint but not specifically stating to only run on server, then multicasting that. So your server will run it and multicast it and then your clients will run it for themselves as well as the multicast.

[dawn gazelle]

Part of your problem is you're running multicasts for everything.

[trim matrix]

yeah in the post i said i couldnt figure it out so i just did it for everyone randomly with multicast and said fuck it lol

[maiden wadi]

What you should actually be doing, is likely spawning replicated knife actors just on the server. Then they'll simply update themselves on the clients as well at least for initial location. If you need to move them, make a replicated vector, or set ReplicateMovement to true.

[trim matrix]

see i tried that exact thing and it didnt work

[dawn gazelle]

You can't do this either. You have to set the variable on the execution path it is on, and then reference the variable on the other.

[trim matrix]

what? thats just to stop the timer from generating more numbers than it needs.

[dawn gazelle]

but you can't hook it up like this.

[trim matrix]

huh? why not? its been working for everything else so far

[dawn gazelle]

Dear god. NO. Keep pins on the same execution path. Never cross them between other execution paths.

[maiden wadi]

Promote the blue pin to a variable, and use that variable to clear the timer. Hooking it up like you are sometimes works, but you're at the mercy of whether the blueprint system wants to hold that reference or not.

Works != GoodPractice.

[trim matrix]

but I tried on begin play, running on server to get the random numbers and make an array of those random numbers and have that variable be replicated, then multicast spawning items but it doesnt spawn anything for the clients because their version of the array is blank i guess.

[trim matrix]

ive no idea what this means

[maiden wadi]

Why though? Just spawn replicated knife actors on the server alone and be done with it. They'll automatically replicate themselves to the clients.

[trim matrix]

so promote the timer to a variable that i hook to the clear and invalidate instead?

[maiden wadi]

Right.

[trim matrix]

no, i spawned items on the server world and didnt see them in clients worlds

[trim matrix]

got yah

[maiden wadi]

Did you make sure to set the actor to replicate? Actors aren't replicated by default.

[trim matrix]

um

[orchid garden]

so i have a question, I need to rotate a camera right or left during a UI drag event depending on which way the player drags their mouse, is there a simple way to do this?

[trim matrix]

actor replication? XD

i know plus its on tick which isnt good XD

[maiden wadi]

https://www.youtube.com/watch?v=09yWANtKmC8

[trim matrix]

but so if i replicated the actor, then if i spawn on server itd just be there?

[orchid garden]

print string on tick - uncheck 'save to log' and set display time to 0

[trim matrix]

i gottah test real fast brb

[dawn gazelle]

I was just giving an example of what not to do XD

[orchid garden]

tick works good for debug display of vars on screen as long as you don't save it to log and set the display time to zero, then it will constantly only show in the one spot, if you have multiple lines it'll look like you have a mini UI for debugging up.

[trim matrix]

@maiden wadi Dude.... i cant believe you just solved both of my problems with one box tick of replicating the actors

this has been fucking with me for 4 days and its all because I DIDNT REPLICATE THE FUCKING ACTOR!?

[maiden wadi]

Multiplayer is pretty simple in the long run, but learning it can be a little tricky.

[orchid garden]

multiplayer replication can make your head spin sometimes

[trim matrix]

it fixed my other issue too because it only spawned one version of the item, so it only responds to the player overlapping it jesus christ dude

im so glad i decided to look up a discord for this. thank you so much

now i can finally move forward with making this game.

[orchid garden]

so my little question, I need to rotate a camera right or left during a UI drag event depending on which way the player drags their mouse, is there a simple way to do this?
anyone know?

its the right / left of the mouse thats hanging me up

[trim matrix]

sorry @orchid garden but just to ask real fast. so if i have items everyone can grab and all, i need to replicate it to have it spawn in everyones world right?

@orchid garden wouldnt u get mouse x/y input and rotate the camera from it?

[maiden wadi]

@orchid garden How is the camera normally moved? Just a floating camera, or like a camera on a spring arm sort of setup?

[trim matrix]

i dont really think i have any input, i couldnt even replicate an actor lol ill leave this to you guys. XD thanks again, have a great day

[orchid garden]

its a camera attached to a spring arm, and isn't controlled by anything at the moment.

[maiden wadi]

What kind of UI drag event? Just click and drag anywhere on screen, or something more specific?

[orchid garden]

for world spawned item pickups and replication i'd have the server create the item, then do a multicast event passing that item and its spawn location to have it populate in the world for everyone, but i haven't messed with replication much,

[orchid garden]

its a drag event over a single widget

[maiden wadi]

Could probably hook into the widget's on mouse down/up function overrides, and set the input mode from there. Possibly either use it's tick or the actor's input actions to add controller yaw/pitch based on the mouse delta.

[orchid garden]

basically what im attempting to do is rotate the spring arm the render cam is attached to so that the player can look at their character from the side, front and back via a mouse drag in the red area.

i can do it with buttons just fine but i thought mouse drag would be better.

[dawn gazelle]

Could you possibly detach the camera from the character and then just spin the character instead?

[orchid garden]

either way would work, but i'd still need to get the left/right of the mouse while dragging

[gritty aspen]

Hi

Can someone help me in something

[orchid garden]

@maiden wadi im trying to steer away from ticks as much as possible

[gritty aspen]

I want to do a ui button for android control i did for jump and move right button
But when i try to do the same blueprint if left button he gave me error

This is the blueprint of the right button

Hello?

[astral epoch]

What's the error message?

Also, can't say I'm too experienced with mobile apps but... is this normally how you handle buttons?

[gritty aspen]

When i copy the (event tick) blueprint he tell me a custom blueprint

And don't work

So i come here if there is another blueprint for this

[astral epoch]

Okay, I see the problem.

You can't just "copy" an event like that.

Because those are "entry points" (for lack of better term)

The "Event Tick" is a special one that is called once per frame, its built into the engine so you only have one of them for each blueprint.

Does that make sense?

[gritty aspen]

Well i understand what you said but is there another blueprint to let the character move left

[dawn gazelle]

You'll need to overwrite two functions in your widget

You'll need to create a child blueprint of the drag and drop operation class and input it into the "Create Drag Drop Operation" node. The event to capture mouse position is below.

[gritty aspen]

Ok

[gritty aspen]

But it work for mobile

[dawn gazelle]

That function in the event there outputs your mouse X,Y vector. You can use that to then control your camera however you like....

[gritty aspen]

?

I want the character to move left nit the camera

For 2d games

[open crypt]

Is there a way to disable the doubleclicking of a node starting up Visual Studio?

[dawn gazelle]

keep visual studio open

XD

Sadly, I don't know of any way to disable myself ._.

[open crypt]

lol I don't do CPP and it's not a CPP project

[dawn gazelle]

This should do the trick. Set this to false.

[open crypt]

Thank you, you beautiful beautiful person

[orchid garden]

yeah i know i need to override the drag n' drop, thats not the problem, its "was the mouse moved left, or was the mouse moved right?"

[pine trellis]

I have this effect I want to use, but I only want a certain players to see it, does anyone know how?

if i put it on the character mesh material everyone sees it like that

[dawn gazelle]

oh, store the last value it was on the camera, and if the current X value > then the last stored, move right, if < then last stored, move left. You can use the difference between them to rotate it by a certain amount (like 1 pixel = 0.5 degrees or something small)

[orchid garden]

mk i'll give that a go 🙂

[maiden wadi]

The Player Controller has a GetInputMouseDelta, but it only works if you're using InputModeGameAndUI, or GameOnly, and if you're using GameAndUI, the mouse button needs to be down, or else it'll return 0.0, 0.0

But yeah, that's not really that useful if you're avoiding tick.

[orchid garden]

isn't on drag its own tick?

[dawn gazelle]

On Drag Detected only fired once in my testing.

That's why I did the Drag and Drop operation.

And that event only fires if the mouse is moved.

[orchid garden]

what about on drag over?

[dawn gazelle]

Drag over is detecting if a drag and drop event is being dragged over the widget.

[maiden wadi]

On Mouse Move is probably the only event that might work like a tick.

[dawn gazelle]

Gawd I'm blind. I didn't even see mouse move.

[orchid garden]

mk... so i could do it with mouse move and set a var with mouse down / up so it knows if they are attempting to drag in that widget... course i'd have to make a widget for it and add that to the equipment panel.

@dawn gazelle @maiden wadi ty both 🙂

[dawn gazelle]

Yeah this works ok, but it is like tick

[latent arch]

hey all, is anyone versed in the vehicle movement components? im having some troubles! 🙂

i initially had a real eadache importing from blender, but now that "seems" to be ok

im showing the bones and they appear in the correct place

but when i simulate / play the vehicle behaves as if all the wheels are in the centre of the vehicle despite naming the correct bones for them

[orchid garden]

it looks like its your bone setup thats the issue

[open crypt]

I've got a PredictProjectile Path that takes in an array of ActorsToIgnore - how can I make it ignore the components of those actors?

[orchid garden]

when the wheels are being attached to the bone, they aren't attached to the tip, they are attached to the starting point.

so you'd need root>wheelarm->wheelattach bone setup and attach the wheels to the wheelattach bone.

it looks like you just have root->boneforwheel

make sense @latent arch ?

[latent arch]

oh i see yeah that sorta makes sense, how can i swap ends? 😄

not sur ehow to change it

[maiden wadi]

I think he means to add an extra bone on the end.

[orchid garden]

yep

[maiden wadi]

Do sockets work with wheels like that? Could use those if you don't want to reimport.

[orchid garden]

or you might be able to do it by adding a socket to the existing bone

[maiden wadi]

⬆️ This arrow is better

[orchid garden]

heh just thought about that too @maiden wadi

[maiden wadi]

That's one of my grey areas. Haven't messed with vehicles much.

[latent arch]

hmm ok ill try adding a socket to the ends

[orchid garden]

then attach the wheel to the socket and use that for the rotation of the wheel.

[latent arch]

its odd because they are all separate bones at the wheel locations not sure why they are attatching the the centre the wrong way round lol

yeah ill try it now thanks 🙂

[orchid garden]

all the bones start at the center, rather then the end point, thats why the wheels are ending up in a pile in the center

[open crypt]

how can I get components of these actors to be ignored

[orchid garden]

if the actor is in the ignore list it should be ignoring anything attached to that actor shouldn't it?

[latent arch]

hmm just tried the sockets and same problem

[orchid garden]

is the socket a child of the bone?

[latent arch]

this is the bone setup that im using, its a copy of a turorial / working project asset so im stumped

[orchid garden]

the bone thats extending out to where the wheel should be

[latent arch]

yes

[orchid garden]

and when your adding the wheel your setting the socket as its parent?

[latent arch]

yep

[orchid garden]

im lost at that point then, logically it should be ending up where its positioned.

[latent arch]

yeah my thoughts exactly!

[grizzled garden]

help
https://streamable.com/74prqi

why does it hit only one at time?
i used the array and it should hit all of them
but it does hit one at time only, pls help me

[latent arch]

it all looks to be correct but its not working lol

[orchid garden]

only thing i could say is check the socket location in game see if its being moved to the center.

its either the socket or the bone getting set to the 0/0/0 position of the root.

[latent arch]

no its not cause i got the socket location and drew a debug capsule round it

its definately at the wheel 😦

[orchid garden]

:/

[latent arch]

so either the wheels arent attaching to the sockets or the bones are the wrong way round

just doenst make sense!

[orchid garden]

or the wheels position is being set to the center of the root.

your bone structure looks right from the image

[latent arch]

yeah i just cant see why it would use the root bone rather than the ones named though?

[odd ember]

maybe it can't find your named bones

so it defaults to root bone

[trim matrix]

hello im back i have another problem that maybe someone could help me with

[latent arch]

@odd ember that sorta makes sense but id have no idea why cause i literally copied the names

[trim matrix]

when i click on an item in my game it highlights it and sets the variable in character as the highlighted actor, now when i hit the interact key it throws a message to the item to destroy it, but only the server can do it, if i try and do it with the clients it wont destroy or anything.

i have the actor to replicate so would i still need to send it to server then to everyone else to do it as a client?

or could i not just destroy it on client and since it replicates, itd be gone anyway

[dawn gazelle]

Just run on server and it should destroy on all clients if it is set to replicate.

[trim matrix]

ok so im doing it through interfaces

so if player hits interact key it sends a message to item to destroy. where would i need to place the is server check?

[rough wing]

From that message

On the items event, call a server custom event

[trim matrix]

so inside the item?

[rough wing]

And destroy the actor from there I guess

And if it doesn't replicate to clients

Try running a multicast within that server event

[odd ember]

I can't answer that for you

[trim matrix]

well what im saying is the actor doesnt even destroy on the clients side at all either

[dawn gazelle]

Was the actor spawned on the server in the first place?

[trim matrix]

yes server spawned the item in from level bp

[orchid garden]

player pickup ->server check if valid -> initiating client pickup item -> server destroy item?

[trim matrix]

and actor is just replicated

[rough wing]

Can you send a screenshot of what you already have

[trim matrix]

@orchid garden is that in player interface?

ok one sec

i have a system where when i click an item it highlights it and sets a veriable in player that the actor is now the highlighted actor

then in item on interact the item checks to see if the player that sent the message is one of the players in range, and if so, is the highlighted item this item? yes? then destroy

[rough wing]

Okay I think you're trying to delete the item one by one on every client right?

[trim matrix]

so if i do it on the server, it destroys it on all clients

if i try to interact with client, it doesnt even destroy on their own world. nothing happens for anyone

[rough wing]

Sorry I read it wrong

So you only want one person to delete the item

And on every other client the item should still be there?

[trim matrix]

no

i want that item to go away for everyone if anyone picks it up

[rough wing]

Okay can you create 2 custom events

[trim matrix]

it works for server, it dissapears from everyones world when server picks it up

but if client tries, nothing happens for anyone

[dawn gazelle]

Your interact should be calling a call to server which fires the interaction message

like this

(to the left side is my "interact" button which is off screen)

[rough wing]

Create a custom event>Set it to run on server>attach the destroy event to that event

And call that event from the message

Like in daturas screenshot

[orchid garden]

@trim matrix very basic makeup of what i was meaning:

[trim matrix]

and i place that in the item bp?

[orchid garden]

course you'd write your bits for the coding inbetween the event calls

[rough wing]

Wherever you place it it will run that part of the code on the server

[fair magnet]

hi there... uhm.. I'm back again ! and now my problem is... my animation is glitching around :o might be caused by the calculate direction node

[dawn gazelle]

One of the things you have to keep in mind when programming multiplayer is to never trust clients. They can press a button, but the server should verify everything that should be happening on its end.

[trim matrix]

hm let me try it

brb

[solemn parcel]

Hi, just changed my FirstPersonCharacter Blueprint by another one, and for some reason I have now two crosshairs. Any clues ?

[errant cradle]

guys, how can i get user hardware info in bp
such processor, graphic card ?

[trim matrix]

I tried what i think you meant and no dice

[dawn gazelle]

remove the branch, the InputAction Interaction node should be plugging directly into the Server Interact function call.

The server should be the one figuring out what the "highlighted interactable" is as well.

[rancid ocean]

Anyone know how to convert an (unix) Epoch to Date in Blueprints?

[dawn gazelle]

or, you'll have to pass it into the event

[orchid garden]

make sure the trace for the object they are interacting with is done on serverside as well so that you get the correct object reference

[dawn gazelle]

There's a free plugin that has a blueprint node that helps with that.

[rancid ocean]

Great I saw an old one but figure it would be in engine now.. do you know what is called?

[trim matrix]

got it to work like this,

idk if its the most optimized but it works

[dawn gazelle]

It's LE Extended Standard Library, but there's a specific way to do actually do it in the BP... trying to find where I had done it in my project.

[trim matrix]

thank yall for yalls help again

[dawn gazelle]

Seriously, get rid of the branch there. That's going to &$%*@ things up.

[trim matrix]

ok

[orchid garden]

@trim matrix remove the branch and the call to interact its attached to and just have it go strait to server interact. Even if its a single player game it will still function normally this way. Doing client only calls for pickups on a server will mess things up.

[trim matrix]

I fixed it, thank you

[fair magnet]

Does anyone know what's wrong ?

[errant cradle]

how can i retrieve pc specs?

[rancid ocean]

@dawn gazelle Thanks I will see if i can get it to go.

[orchid garden]

so on my little rotation thing for the widget, when using mouse move, if a button is pressed it doesn't fire off the mouse move event, it works great if a button isn't pressed, so its gotta be firing off a ondrag for it.

so it doesn't look like its possible without a tick

[solemn parcel]

How can I force the FirstPersonCharacter to keep running even after release of the input, until release of axis walking inputs ?

[dawn gazelle]

Did you overwrite the preview mouse button down function too?

[orchid garden]

no didn't do that i'll try now

[open crypt]

Just to understand performance - what's the difference between casting to an object versus comparing the actor hit to an object class?

[covert delta]

I'm trying to get an actor to slowly rotate over time towards another actor. I'm using RInterp to do this. When the interp speed is set to 0 (so it snaps, according to the tooltip) or if I just don't interp at all, the actor immediately looks in the right direction. When I interp with some small positive speed however, he seems to rotate towards the wrong direction. Am I missing something here in this setup?

[dawn gazelle]

Toggle the boolean on another key

Like so

[fair magnet]

@dawn gazelle you have smth wrong there :o shouldn't it use the set scale value if it's on ? :D not when it's off ?

[dawn gazelle]

Erm... I thought I fixed that before I pasted the screenshot

Good eye XD

[orchid garden]

still only fires once and doesn't track mouse movement while dragging

[dawn gazelle]

Dang. That seemed like a good solution :/

(the whole using mouse move function)

[orchid garden]

yeah you'd think there would be a override for that but guess not.

[solemn parcel]

@dawn gazelle You propose me to bind the autorun to another key ? that's not exactly what i was searching for :p I really want the input to run and autorun to be the same, just want to running to stop when any axis input are released

Or i got it wrong

[gusty cypress]

Is there a way/term for an automated way to change a variables name? I'm making a patformer with different levels but they all have different stages, when creating the TP to next stage mechanic I have the destination as the next spawn variable, instead of resetting that each time can I change the variable it uses, exp. all my spawns are called "spawn#" so could I have a way to delete last the last value (number) then add one to that number and replace it?

is essence the bottom right shows my new spawn variable, can I simply have a way to change its variable name as it exists within the levels as (spawn1, spawn2, etc.)

[woven wing]

You probably don't want to change the variable name.

[gusty cypress]

rather what it references

my current alternative would be right before this is called SET a new one

[woven wing]

Is your spawn location a specific type? Like a blueprint?

Like - is it an object that indicates where the character should spawn?

[gusty cypress]

let me show you

this is my current setup that would work

[woven wing]

OK, but what is "Spawn2"

Is it a particular blueprint?

[gusty cypress]

within the level blueprint when the trigger for next stage is hit 2nd pic is what happens and it calls the first pic which is my gamemode bp

just trying to streamline it

[woven wing]

Sure - that's fine. But what is it?

[gusty cypress]

im sorry?

[woven wing]

Spawn2, what type of object is it?

Is it a static mesh?

An Empty?

A box trigger?

What is it?

[gusty cypress]

empty actor, sole purpose of providing a location and rotation so I dont have to manually enter all those values

[woven wing]

OK.

So my recommendation would be to make a class called "PlayerSpawner".

Which is just an empty actor blueprint.

[gusty cypress]

Ohhhhh

[woven wing]

Then you can do this:

Get All Actors of Class will give you all Actors of type Player Spawner.

Then if there's one of them, you can use that one as your target.

Now you don't even need to worry about what you name it.

As long as there's a PlayerSpawner - you can use that as your spawn location.

[gusty cypress]

thank you I will do that!

[woven wing]

(Unreal has a built in version of this idea with the PlayerStart objects)

https://docs.unrealengine.com/en-US/Basics/Actors/PlayerStart/index.html

[dawn gazelle]

I'm not sure I fully understand what you're asking. When you're holding down any axis, you are running. If you let go of the axis, you stop running. Perhaps this? You can let go of the forward key, but if you're pressing left or right, then he'll keep moving forward until you aren't holding any keys down.

[orchid garden]

what if.... you want to use the actor as a base location then randomly spawn them x distance from the spawn actor but not end up under the ground?

[maiden wadi]

@orchid garden That's fairly easy if you have a level ground and you know the gorund's Z level. Otherwise line traces may be necessary.

[winged badge]

is there a way to test an internet connection through blueprints?

i know when using windows normally, using a ping google console command is the usual choice

[tough raptor]

I made this question this morning, but I want to try again as I didnt got a satisfying answer.
I want to make a sword trail. At the moment I make this by connecting dots from a line trace, but eventually I want to switch the system so that it functions with the location the overlapping of the sword and the object yields.
I have been looking into it and I cannot find a way to get a sweep/hit information every frame from the overlap.
Is it even possible to make this, or should I just forget about overlapping every frame?
Thanks alot in advancee 😊😊

[solemn parcel]

@dawn gazelle I think it's close to what you say. If I hold down an axis, i'll walk, if I hold down 'Shift' while walking, i'll run, while running, if I release 'Shift' I will still be running until I release axis key (the walking keys)

[orchid garden]

mine works like -> forward walk, ctrl, toggle jog (only jogs forward when pushing key), hold shift -> run, release shift walk or jog depending on ctrl

[solemn parcel]

@orchid garden Yeah 3 types of 'speed'

I'll keep it simple and keep 2, but with the run on autorun

[orchid garden]

autorun is usually just a toggle feature for most games done like @dawn gazelle 's example

three speed thing wasn't too hard to setup, its all set by the server then passed to clients:

[solemn parcel]

Autorun 'was' more of a toggle feature until last years, where most fps/tps these days move toward faster movement, leading to more freedom on the running input, leading to a running more like what i'm searching for I think

[orchid garden]

so pushing forward you want to start out walking then slowly move toward a run.. can't help with that never tried 😦

[solemn parcel]

@orchid garden Still want the InputAction Run to be pressed to activate the running speed, and keeping that speed, even after the InputAction Run is released, as long as there is still an AxisInput pressed.

@orchid garden No problem 😉 I'm learning anyways !

[orchid garden]

i'd imagine it has something to do with velocity

but i could be very wrong, i've only done some basic animation stuff sofar

[maiden wadi]

I'd imagine that the most user friendly way to manage that would be for a separate W key as an Actionmap along with the W and S axis map. On W action map release, toggle the max speed back to walk. On Shift press or W press, check if the other is down, if both are down, toggle the max walk speed to sprinting speed. Don't change max walk speed back to walking speed on shift up.

Then you're not checking it every tick on an axis mapping.

[solemn parcel]

@maiden wadi I'll try this ! Thanks

[maiden wadi]

Double checking my logic train of thought.

@solemn parcel This more or less. Depending on your movement style, you may need to check other keys like ASD as well unless you only want sprint to work on W

Whoops. Messed up the input thing.. that should probably be a function with a switch...

[orchid garden]

mine just sets a couple booleans for the toggle keys then tells the server to get the speed, and tell the clientst o update the movement:

so its handled seprately from the movement axis

[maiden wadi]

This is fair. For multiplayer, that changes a little. Server needs to be notified.

[orchid garden]

(warnings are because its in a test project with no keys setup)

server is notified when they press the toggle key -> server update movement

[maiden wadi]

But yeah. Multiplayer or no, it's mostly just a logic check

[orchid garden]

i've tested it, and it works for standalone, client to client and dedicated.

[unique wyvern]

do tick events in behaviour tree tasks automatically stop when the task completes finish execute ai?

[orchid garden]

the hardest thing i tried doing was a double jump thats replicated to all 3, that was a pain.

[maiden wadi]

@orchid garden Launch Character should work for the second jump I think.

[orchid garden]

@maiden wadi i ended up using Launch Velocity for the second jump

[orchid garden]

i should probably convert it to use your double tap method to determine if its a double jump 😉 be much cleaner then what i have right now.

[gusty cypress]

general question: is it okay to store every temporary value in the gamemode bp, exp variable = current level

[maiden wadi]

I love that double tap macro. I don't use it nearly enough. 😦

@gusty cypress Not exactly certain what you're asking?

[gusty cypress]

@maiden wadi best place to store temporary variables?

gamemode, game instance, ??

[maiden wadi]

What are they for? And what is temporary?

[dawn gazelle]

how temporary? 😛

[gusty cypress]

while the game is running, exp. the name a level, this would be reset each level but it would be a waste to have a "levelname" on each level bp instead of one that is persistent throughout the game being open

[dawn gazelle]

Would you need to reference level name elsewhere in the game?

[gusty cypress]

no but it would be 1 variable in the gamemode bp being set each time a new level is loaded versus having a different level name vriable of each level bp

[dawn gazelle]

I'm not sure how many levels you intend on having, but it would be more wasteful for the computer to have to store the values of all the levels if they're not going to be referenced anywhere else.

I would say if you had a level select thing where the name would be displayed, then you could store the data in a table and you can reference it whenever you want, but if it's only ever going to be shown in the one level, then you may as well store it in the level.

[maiden wadi]

If it's just a name that's changed every level, then GameMode would work if it's single player. GameState if it's multiplayer. GameInstance could possibly work too for single player. The issue with putting it in the level blueprint is that it'd need to be placed separately in every level blueprint, and it also makes it hard to reference from like UI or anything unless that UI is spawned from the level blueprint. Just really depends on your use case.

[gusty cypress]

true I forgot the pain of UI referencing and levelBP

[tight schooner]

Game Mode etc. are just useful built-in manager classes. You can use them for whatever, really...

GameInstance is different in that it persists across level loads

[gusty cypress]

is gamemode not persistent across all levels?

[maiden wadi]

Nearly everything except for GameInstance is destroyed, and recreated each level load.

[gusty cypress]

so before when you said the gamemode bp would be storing useless values isnt that not true once levels switch?

[maiden wadi]

Is it just one single string?

String/Name/Text^

[gusty cypress]

the level name is 1 string, I also have strings, vectors, ints

[maiden wadi]

In the end, it just depends. The thing is, the best case for everything is different depending on a lot of factors. Like Seanny said, they're just premade managers. You can choose to use them how you want. There's a common way that people often do, and there's a definite way to use them if you're working in multiplayer, but single player is very relaxed in that regard. Make it work, do it in a way that you yourself will understand it if you need to look at it again. If you learn something new or want to optimize it later, reiterate on it.

[gusty cypress]

thanks, as a single player project I have found little issues

[orchid garden]

why not just a world actor to store the temp variables in then just transfer the variables you need to carry to the next level into gamemode or the player controller?

[gusty cypress]

I thought the gamemode wouldnt transfer into the next level

[orchid garden]

idk just reading what you guys were talking about

[rough wing]

How can I block all input coming from a blueprints parent?

[covert delta]

what does input mean in this context?

[rough wing]

Keyboard input

player input

[covert delta]

so you mean, ignore the events of the parent that react to a given input event?

[olive sedge]

An FInterp of a rotation from 179 to -179 is really long, is there a function that goes the short way via the 180 cutoff?

[rough wing]

Yes

[covert delta]

You can override them in the child class and just don't make them do anything

[rough wing]

Is there no short way of blocking complete input?

[covert delta]

I think you can call disable input? But that's not blocking the PARENT, that's blocking the player controller

[olive sedge]

Can anyone tell me how to avoid this?
https://i.imgur.com/28ThMkP.gif

This is my bp for it:
https://i.imgur.com/l93RwcZ.png

[orchid garden]

how is the little guy on his back attached?

[olive sedge]

I could theoretically read the aim rotation and then do the rotation the other way but I don't know how

[orchid garden]

thats what your talking about avoiding yeah? him pulling away from the actor?

[covert delta]

no. he's saying he doesn't want the actor to turn 359 degrees clockwise instead of 1 degree counterclockwise

[orchid garden]

ah my bad

[olive sedge]

hm, good question actually.. I'm not sure what causes this. I just think he rotates from 0 to 180 and should rotate so he's facing the enemy

hm! I think this only happens when the interp isn't done yet

so the interp is actually faster the way he does it

but doesn't make sense

so any way to give the RInterp a direction?

[latent arch]

🤯

im at a total loss here lol

[orchid garden]

lol sry to laugh @latent arch but that video was just too funny reminds me of my trials and errors lol ... it looks like they are rotating on the wrong axis

i donno about the turret though might be the same thing

[tough halo]

I have made a simple bullet penetration mechanic. I want to put a penetration resistance variable in material so if I hit wood it can go through, but steel will stop the bullet. Can I do that?

[latent arch]

@orchid garden haha! :F

sorry i sent the wrong video!

[tough halo]

basically I have a hit event, if I hit an actor I can cast to a base actor and put it in there, but if I hit the ground, or just some mesh that isent an actor

how can I put some data in there that I can get in a general way?

[latent arch]

This is the video i meant to send

the physics of it seem ok now, but the wheeled vehicle component and the wheel locations are just WTF?! 😮

[tight schooner]

@tough halo I think it's possible to assign physical materials to collidable objects and have a Hit event return that material. Maybe you can do something with that.

[tough halo]

thanks seanny

Event hit has a "Other comp" thats a Primitive Component Object Reference

the way I want to do this is to cast that to some baseclass/interface type thing that then can have stuff like penetration resistance or maybe a "skip penetration check" bool

maybe thats the wrong way to go about it tho

[stiff chasm]

guys i compiled my code but it keeps giving me an error

what do i fix?

same with this

[tough halo]

its easy, you press ctrl+a, then the delete button

it will compile easy

[stiff chasm]

oh ok i see, thank you!

do i do the same with this too?

[trim matrix]

How would you use a vector to set the angle of an object? So it would set the -z axis to point to that vector?

What I am doing is getting the velocity of an object and I want to orient it so the object points in the direction it is moving

[tough halo]

that looks like its just gonna work as is @stiff chasm 😄

[trim matrix]

I dont see anything wrong with that code... You're sure that you are getting a compiler error?

[tough halo]

@trim matrix I'm no expert but you can probably use a setActorRotation node and just drag your vector into the rotation input

it should be converted from a vector to a rotation

[trim matrix]

That causes the object to spin around a lot and it looks odd :p

[tough halo]

where do you get the vector that represents the rotation?

[trim matrix]

I am using a getPhysicsLinearVelocity node to get the velocity of the object, and converting it to a normalized vector and putting that into the setWorldRotation node (Some parts of the actor need to stay still like the collision, so I am using relative rotation to prevent the collision from rotating)

:p

(This is the result)

[tough halo]

I dont really understand whats wrong with that

when they are falling they are rotated downwards?

[trim matrix]

No the rotator fails to get their direction and orient the rotation properly, and it flips rotations constantly.. (The arrows are supposed to be pointing straight in the direction of movement but when they are falling down on the right, the arrows rotate around very quickly, and randomly... they are not pointing in the direction of movement)

[tough halo]

can you change it to drop just one instead of alot?

then print the vector you are using to set the rotation

probably the velocity vector keeps spinning, which leads to the rotation spinning

what are the arrows?

[trim matrix]

The arrows are pointing straight down in the blueprint for me to see if the object is being rotated properly... If this were to work right they should be pointing where the objects are moving

[tough halo]

so it's just an arrow component

[trim matrix]

Yeah

And now for some reason deleting it and replacing it with the same nodes seems to have fixed it?

Im so confused why cutting and pasting fixed it but thanks for the help on the rot from X :)

[tough halo]

hey, if it works it works

[orchid garden]

your wheels still aren't working right, if you look at your video at 0:24 all the rotators for the wheels are in the center of the tank

I've got a odd bug I can't seem to figure out...

If the player equips a bag, the inventory slots for it show as zero UNTIL they equip a backpack, then the slots for the bag show properly.... I've been trying to trace the problem but i just can't seem to find it...

[latent arch]

@orchid garden yeah i totally agree, tho i have no idea why that is considering ive suposedly attached them to the bones 😦

th eonly thing that seems to "work" is aplying offsets but that feels very dirty

need to figure out wht the bone locations arent working

but i have my suspisions its a scaling issue from importing the mesh :/

[orchid garden]

i donno if this will help but ....
https://youtu.be/Oh7pDL8RFaI

[latent arch]

hey man, thanks for that. unfortuantely not as its a different method hehe 🙂

thats a good tut though

[orchid garden]

ah you've already looked at it then

[latent arch]

yeah that is for making a vehicle from static meshes

im trying to do it the "pro" way and do it from a single skeletal mesh with animations lol

[trim matrix]

how do we turn a pawn to where we clicked with the mouse?

im new to unreal and only did the lightbulb tutorial with triggers to turn the light on/off

[orchid garden]

.< doh found the problem it was in my pickup master... had a switch reversed... so wierd though how it was bugging out... seems to be working properly no matter how the bags/pack are equipped now ( 1 at a time, 2 different at a time, etc)

[trim matrix]

@orchid garden

Actually...

Its rotation actually doesnt work

It is now smooth in calculating and using the rotation but isnt pointing in the direction it is supposed to... 🤔

[past girder]

hi, i am using a random integer in range node, but i want to make it have a bigger chance of hitting on of another, how would i go about doing this?

[trim matrix]

Here's with time dilation going slower so it might be easier to see the direction of movement for the droplet. (This needs the ability to move in all 6 directions on a vector and point in the right direction, It wont work for me to just restrict it to one single rotation axis)

[orchid garden]

i was going to point you to a project that epic had in the market for free, but it seems they removed it 😦 it did exactly what you wanted.

however....

In Epic launcher, if you click Unreal Engine, then the Learn tab, and scroll down to the very bottom there is a project there called 'turn based strategy' that may show you how to do that.

[tough halo]

so after the bounce it should flip around so the arrow is pointing in the direction it's traveling?

essentially the arrow should always point in the travel direction?

maybe there is some sort of conflict with the physics stuff so it doesnt wanna rotate

[faint pasture]

@past girder just do a random float 0-1 and map it however you like

[sturdy herald]

Hello!
Someone can help me with this package error?
The only supported platform is Windows, all the others are unchecked.

[deep imp]

Oh my god the ability to copy and paste functions from one blueprint to another is AWESOME! God I love UE

And variables too. W00t

[sturdy herald]

omg, this is a new information for me. Thank you :))

[trim matrix]

HECK YEAH NEVERMIND I TOTALLY FIGURED IT OUT

@tough halo Yeah I had some parenting issues with the physics so ended up using a spring arm which doesnt inherit any of the rotation of the sphere collision... It looks like it worked perfectly :)

[tough halo]

nice

that was suprisingly satisfying to watch

[trim matrix]

Haha yes indeed 😄

[gusty cypress]

dumb question, do comments affect size of game

[mortal nacelle]

Does anyone have tips for doing data-driven instantiation of objects, in multiplayer?

e.g. I just want to have a BaseItem class and pass in an ItemID parameter, which does the rest through DataTable lookups (finding the correct mesh, etc)

it seems to work ok if I use a replicated variable w/ "expose on spawn" and then do my configuration in BeginPlay

[winged badge]

For some reason these nodes are available out of box for any ue4 dev

has anyone gotten them to work on windows?

[trim matrix]

quick replication question
i set my player up for on begin play it creates a widget hud and adds to viewport, as you may know when the clients join they also make one and add a second and third hud to the servers hud. so clients have one but server has 3. how can i make a hud widget just for clients and not make another one on top of servers

[ebon knot]

Not sure where to ask this but i was makeing something with a tutorial blueprint in ue4 and i see that it’s stuck on the screen in the middle i want to have an option to have the user be able to move it around is this possible?

[dawn gazelle]

[ebon knot]

yesyes thx

[dusk basin]

Im having a issue where my default pawn class is not spawning in my custom gamemode it only seems to be working when i place a thirdpersoncharacter in the world any ideas?

[tight schooner]

@gusty cypress dunno but I assume comments are removed from the "compiled" BP

[dawn gazelle]

Did you override any functions in your game mode?

[eternal rock]

Can someone please help me? Im trying to set up box triggers to start playing dialoge when a player overlaps it, but for some reason, only the first one works. The other 2 wont work unless i take off "destroy actor" from all 3 in the level blueprint. Why would it destroy my other trigger boxes?

[trim matrix]

it’s not like I ever use the level BP so it’s not like I know any technicality’s as to how it works. But seems to me that the Destroy Actor function might be destroying the level BP.

Which would make sense if the level BP was technically just like any other actor in the scene.

Anyways it seems like your not fully understanding how to plug things up properly.

To fix this, you will need to take the Other Actor output from the On Actor Begin Overlap event. Then plug the Other Actor into the corresponding destroy actor node.

Like this. @eternal rock

This is because the Destroy Actor node requires a Target. The Target represents which actor the node will destroy.

If the Target is left blank (nothing is plugged into it) it will default to destroying Self. Destroying self means destroying the current blueprint.

[eternal rock]

@sterile blooma Thank you. I am very new t o blueprinting. I just started school for it. I am trying this now

[trim matrix]

Np. Btw there is also one important thing that your also missing there.

[eternal rock]

What? Because its still not working lol

[trim matrix]

Yea lol

So right now

[stray island]

What blueprint school

[trim matrix]

Event on begin overlap represents when the sphere overlaps with ANYTHING at all in your game.

The ground, the player, a rock.

Literally anything sets that off. And when the game starts and initial overlaps are calculated.

It could even set of then.

Which ofc is an issue because I’m assuming you only want the dialogue to play when the player walks into the sphere.

[eternal rock]

yes

[trim matrix]

So an easy way to make it do that. Is to simply check to make sure the thing we overlapped with was a player

Before the dialogue play code gets ran

[stray island]

It lets u decide the over lapping Actor though

[eternal rock]

@stray island Academy Of Art University

[trim matrix]

You can change the collision settings to overlap pawn or something but I am going to suggest the way to handle this using purely BP code.

[stray island]

i meant u can trigger event based on specific overlapping actor not everything

Its (other actor)

[trim matrix]

Yea

Todo this I’m gonna introduce you to something called a cast @eternal rock

Try just right clicking anywhere in your BP window and type Cast to (Your Player Actors name)

So maybe it would be Cast to MyCharecter

Or Cast to ThirdPersonCharecter

Whatever the name of the player actor is.

[stray island]

So u study unreal engine?

[eternal rock]

@trim matrix Thank you kindly. I will mess around with this. tomorrow morning. too tired lol

Thanks again! Appreciate it

[trim matrix]

Oh lol ok then have a good sleep

[eternal rock]

@stray island well the class im in now (Scripting 1) is teaching a little bit about blueprinting and we also learned about c# in Unity

[stray island]

Oh what about art

Level design

[eternal rock]

Im more into level design but i have to learn a little coding first

yeah

they have different areas you can choose

[stray island]

Do they teach level design

[eternal rock]

Concept Art, Game Deisgn/Level Design or Programming

yes

[stray island]

Online course or id need to attend

[eternal rock]

next semester i take Action Adventure & RPG Level Design

online!

and the classes are awesome

im learning alot

So i picked Game Design/Level Design as my focus so you still have to learn some scripting because knowledge you need to learn in the field

ok guys im so tired

good night!

look them up though

i highly suggest it

[plain flare]

Hey I'm trying to make, If enemy see me, and after 3 seconds, if enemy still see me, i want to print "see". How can i do this ?

In this code, if enemy see me, 1 time see also ok, after 3 seconds, write see

But i dont want to do this

I want to do: Enemy saw me, ok, but if enemy still see me in 3 seconds, then print "see".

How can i do ?

[shadow saddle]

can i ask UI related question here

[plain flare]

If UI's code part, yes

If design part, no

Please help me, I stucked on creating that code

There we have "On Pawn See". Is there "On Don't See Pawn" or something ?

[tidal willow]

Cast Failed -> set to false?

also the cast would have to be done again after the delay I reckon

[plain flare]

Hey, enemy is overlapping with wall and other stuffs, and printing "overlapped". But i dont want to do it. I want, If enemy collide with player character, than print "overlapped". Not with walls

How can i do ?

Like that ?

[gaunt monolith]

get player pawn

and ==

or equal with other actor

and branch from that

[maiden wadi]

I find the default sensing components a bit lacking. They're okay for very simple uses, but I tend to just make my own specialized component for AI in projects.

[earnest tangle]

@maiden wadi out of curiosity, what features do you find it's lacking?

[mental tendon]

hey guys, how's it going?

Just wondering if there is a way to use static events (similar to C#) in BP something like "static event dispatchers". I subscribe to the static event and I can get notified if any of the instances call it.

[earnest tangle]

afaik no, you'd need to put a dispatcher on some object that will be the "centralized" source for it

[maiden wadi]

@earnest tangle PawnSensing first off, as the name implies is only for Pawns. Which means if you need your AI to see something other than pawns, it won't work. Maybe you want to update your AI when there's a health kit nearby? If your health kit isn't a Pawn, it can't sense that and they need some other way to check that. Why not just include all of that in the same sensing component? Also as far as I'm aware, PawnSensing has no memory. It's all just triggers. So it's up to you to decide how you want to use it. It's a glorified sphere component with OnBeginOverlap function. It's okay for like simple shooters where the AI just runs after the first thing it sees, but for anything more, it's pretty "Eh".

[earnest tangle]

Ah

Yeah I don't think I've actually used PawnSensing... I've been able to make my NPC's sense actors just fine I think by just registering them with the sight sense

[maiden wadi]

ImmutableLambda made me reconsider my stance on Behavior trees, so I started using them again. But before that I had my AI all set up as basically a state machine in it's own class and my component was holding all of the 'memory' variables like the best target, current target to shoot at, close by interactables, etc. I'll probably do this project's sensing component to work with a blackboard instead.

[covert stirrup]

Is it normal to get huge amounts of lag when dragging a parameter in a material instance?

not talking something insane here, a simple setup with 1 slider changing, manual typing in the number is fine, if I slide it around ill get lag for a few seconds

[maiden wadi]

When you drag, it changes the shader every tick in the engine. Possibly effects the things in scene as well. A lot of updating to do.

[covert stirrup]

I don't remember this being the case a few versions ago

[maiden wadi]

There may be a setting somewhere for that. Let me look.

[trim matrix]

@BerkeRam#9339 use AIPerception as it has a pawn perception updated node you can use that will fre when the AI loses sight of the player.

Pawnsensing is very lackluster and is no longer being updated, eventually it will be unsupported AIPerception is superior when it comes to more complicated sensing so its better to start learning that. Pawnsensing is still very good for simple sensing purposes though.

[tight schooner]

@covert stirrup are we talking about... blueprint? If it's an exposed parameter in a BP, it may be re-running a heavy construction script if your BP has one

[covert stirrup]

its a material parameter

[tight schooner]

you just straight up have the material instance editor open and you're changing a scalar value?

it shouldn't be heavy at all

[covert stirrup]

yea, it's super simple too

[stray island]

Can i have a texture sample in the instance

[covert stirrup]

add a texture, then right click and turn it into a parameter

@stray island

[stray island]

Oh

Then id be able to change it in instance

[covert stirrup]

not all texture samples are the same though, so it depends what you are doing but if it's standard texturing youll be fine

[stray island]

What about the its values of landscape cords

[tight schooner]

future material graph questions should be asked in #graphics ... lots of experts in that area there

[stray island]

Sorry

[maiden wadi]

I do get a tiny slowdown with like two hundred things using the MaterialInstance and changing the slider with them in screen, but I have to change the slider for like five seconds and then stop and it's like it's "catching up".

[covert stirrup]

^ yea I noticed that when testing it now

if I limit the slide values to something small, then drag up and down repeatidly I can recreate it no matter what

it's like a delayed lag, not necessarily the action your doing at that moment

[maiden wadi]

🤷‍♂️ I'm a blueprint user who's used to creating construction script stuff. I don't drag change values for fear of mechanical meltdown. 🤣

[covert stirrup]

haha

I have put up with it for a long time and don't remember it being in every UE verison

[maiden wadi]

Then again, that's stuff like.. Lets drag change the seed value that's spawning ten thousand foliage ism instances.

[alpine terrace]

Did anyone run into the issue that a character pushes other characters away?
I googled so much but I did not find any solution

[maiden wadi]

If I have that problem, it's usually due to something on the character that can affect the pawn collision channel. That's why even the default Character mesh doesn't block on the Pawn channel.

Only the capsule usually should block that channel.

[alpine terrace]

Could that sword be the issue?

[maiden wadi]

If you want to test, make sure that everything except for your Capsule on the character's collision is set to QueryOnly or No Collision.

[gritty aspen]

hi guys

guys is there a way to use event tick two times

or for two button

[trim matrix]

Sequence? @gritty aspen

What do you mean?

Connect it to a custom event?

You could make your own event tick

That question is super awkward

[alpine terrace]

@maiden wadi for me only no collision and physics only works

it was the sword causing these effects

Not sure why queryonly does not work

[gritty aspen]

how to create my own event tick

[trim matrix]

@alpine terrace is the object thats being moved set to static? Or is it movable

?

[alpine terrace]

I think as @trim matrix mentioned the sequence should work fine for you

it is a movable character

another player or npc (monster)

[trim matrix]

If im not mistaking, setting something as movable means that it can be pushed around

[alpine terrace]

well i took my character for example placed it on the map

and run into it with the same character

where can I change it to static?

@gritty aspen I don't think you can make your own event tick, you only can take the default one

[trim matrix]

Maybe in the details somewhere. It should say static movable and dynamic I think?

Im in bed so I cant really look for it for you

[alpine terrace]

okay I ask my friend Google haha

[trim matrix]

What I meant by your own event tick is a custom event that is called by event tick

[gritty aspen]

ok how i can d o it

[trim matrix]

https://docs.unrealengine.com/en-US/Basics/Actors/Mobility/index.html

It will show you here. I hope this is the solution to your problem.

[trim matrix]

Create a custom event and name it whatever you want. Then in the event tick node just call the custom event you made..

[gritty aspen]

ok

[alpine terrace]

@maiden wadi and @trim matrix thanks you two! ❤️

[trim matrix]

Im not sure what youre trying to do but Its probably not a good idea

@.

[trim matrix]

Did it work?

[surreal peak]

:D probably has half the games logic on one tick event and now wants to put another half onto it

[trim matrix]

LMAO

[alpine terrace]

@trim matrix I will try it later for now I take a break because changing the collision on my katana already fixed it but I will try your suggestion later too

[trim matrix]

Oh if its fixed then thats great. But I was just saying I dont think its necessary to set things to movable unless you directly want them to be able to be forcefully moved by other objects in the world

On that note. Have a good night man

[alpine terrace]

Yeah but on the character blueprint there is no option

The option should be under transform

[trim matrix]

Oh I hadn't noticed that before. Sorry about that haha. Hope the katana thing works out

[alpine terrace]

yeah but the link you posted says actor mobility

and it looks good but I cannot find it lol

[trim matrix]

I am still laughing at this comment. 😂 😂 😭

[gritty aspen]

[trim matrix]

Im sure youtube knows

nothing

[maiden wadi]

Uh. You should probably check out the default third person template? It does gamepad movements.

[surreal peak]

You did not search for 1 month.

You probably didn't search much at all.

Cause that was a 3 second search and I found a tutorial.

And that even with your used words.

And there is a lot more if I adjust the search terms a bit...

[maiden wadi]

@sturdy herald Are you trying to package for IOS?

If not, someone mentioned that disabling IOS from their engine fixed that when they were packaging for Windows.

[sturdy herald]

Nope, i want it only for Windows, if i already selected only windows in Supported Platform, this is where i should disable IOS?

[maiden wadi]

Hmm. I dunno. Not sure why it's bothering with IOS stuff if you're just trying to package for Windows. I don't even have IOS stuff installed for my Engine. But this dude says he just unchecked it in this screen.

@sturdy herald File->PackageProject->SupportedPlatforms

[sturdy herald]

@maiden wadi Yepyep, this is what i did last night. Actually this was the only thing what i read on google about this, but for me not helped :/ So i joined this server, hoped that someone else have another solution c:

[maiden wadi]

You could try ditching IOS from the engine. Not sure if that's one of the ones installed by default, but in the EpicGames launcher, click on the down arrow next to the yellow Launch button, and select options, then just uncheck IOS here.

May or may not work. 🤷‍♂️

That's all I could find on that. Past that, harass people in #packaging, They'll probably know better.

[sturdy herald]

I try this, and sorry for writing here, i not even noticed the packaging chat C:
Thank you:)

[maiden wadi]

All good. No one's talking here, so not much of a bother.

[tough halo]

this is how I'm checking if I'm hitting the landscape in my bullet blueprint so I can skip doing stuff like check if the bullet will penetrate

there has to be a better way to do this

does anyone have any tips as to how this sort of thing should be done

I feel like since my landscape is an actor apparently, I should have subclass or interface where I can put some stuff

[maiden wadi]

Better might be to have an interface set up for the penetration system. Make a simple check on hit actor/component that returns false by default, true on things it can penetrate. Then you can do this logic on anything from an actor to a component.

[tough halo]

yeah thats what I want

can I subclass the landscape actor

[maiden wadi]

You'd only have to do the interface in base classes, anything inheriting it can return the same values, or be toggled otherwise.

[tough halo]

I was suprised that was an actor to be honest, I was expecting something like a primitive component or mesh or something

[vapid hatch]

is there any way to duplicate an actor in blueprints? (I have a text template, and want to copy it as many times as i need, but change the text) [PLEASE ping me with answers]

[maiden wadi]

@tough halo Even a static mesh dropped into the level is an actor. Everything that exists has to be a part of some actor. Actor is like the base capsule that holds things, and their components are what you see, but components can't exist outside of an actor.

[tough halo]

@maiden wadi thanks for the info. I'm still lacking some basic understanding of how stuff works together

so the landscape I made using the landscape tool has Type landscape

my immediate idea was to subclass it, but I cant find a landscape if I try to make a new blueprint class

[maiden wadi]

Nah, that's why I was saying interface. It'll return false on anything you don't implement it in. So you'd only have to implement it on your classes you want it to return true in. For example. If you don't implement it in the landscape actor it'll return false. But if you have an actor base type named WallActor, then you could set it to true in the base class of that. But then if most walls ahve penetration, but one of your walls is specifically a steel brick with no penetration, you could override the initial implementation to return false.

[gritty elm]

what is the best way to create less gravity object?

[tough halo]

I can make an interface (and probably will once I figure out how things play together), but the landscape actor doesnt implement that interface, and I will have to subclass it so I can add the interface right?

[maiden wadi]

Nah, cause if you run an interface function on something that doesn't implement it, it'll return the default value.

[tough halo]

oh yeah, I get what you mean

everything is actors.. thats actually incredibly helpful

I just leveled up my ue skills

its like you're just handing out free xp Authaer

thank you so much

[gritty elm]

@maiden wadi here is video reference:https://drive.google.com/file/d/1Rhdyzp9WCn56WRneWEl07eAtBwrUMq3W/view?usp=sharing

i need this type of physics in unreal, what method should i use

1: physics constraints
2: radial force
3: add force or torque

[maiden wadi]

That isn't less gravity, that's something with force being added to it per frame.

[gritty elm]

or even hover component etc

[maiden wadi]

Well, to make something 'hover', I'd imagine that you would more or less add force more and more the lower it gets from the hover level, and stop adding force when it's above it. Should give it a bit of an up and down hover effect.

[orchid garden]

that just uses the same thing as a jetpack would (the car)

[gritty elm]

how to implement jet pack @orchid garden

there is also thruster component

so,
1: physics constraints
2: radial force
3: add force or torque
4: hover component
5: thruster component

[orchid garden]

there are alot of tutorials on jetpacks, remember running into them when i was attempting to setup a flying routine (which i ditched as it wouldn't work like i wanted).

[gritty elm]

can please provide tutorial would appreciated

[orchid garden]

https://www.youtube.com/channel/UCdoWGpMQK_L29bWXoDeIItw/search?query=jetpack
here's one from titanic games, its a basic jet pack but it'll give you the idea of how you can make it work. (3 videos)

[tough halo]

say I want a penetration factor/density factor/whatever, something that will tell my penetration logic how resistant whatever I hit is to penetration. If I have a general mesh thats just "wall", which I then can put into the level and scale it to be one side of a house, or scale it down so it's just a little fence or whatever. If I make a blueprint class from the mesh, then implement an interface that has a "getPenetrationResistance" function in it and use that in my bulletblueprint. Then I can assign a "brick" material to my wall, or a "wood" material, and have the interface return a constant from whatever material is set on the "wall" object

is that a good way to go about things or is your immediate reaction "wtf is this guy doing"

😛

[maiden wadi]

It's more likely that you're going to get a better use out of giving the actor an ID or Enum. Then the actor can set itself up with materials in the contstruction script AND return the correct density in the interface based on that one enum.

Then all you have to do is drop it in level and change the exposed enum or whatever and it'll just work. Good for design.

Also works good if you're making a building system. Cause it'll set it up correctly at runtime as well.

[tough halo]

wow

I didnt know I could do that

again thats just incredibly helpful

I know this is like basic stuff, but omg it helps so much to get a little bit of guidance

[plucky gale]

Could anyone help me with moving an image to the mouse cursor? I just started out working with Unreal and have never worked with UI

[trim matrix]

Hey guys, I am attempting to diff a uasset with an earlier revision of itself. When I try to diff, I receive this popup. How can I use the built in UE4 diffing tools here?

[tough halo]

Bullet Hit Me is an event I can implement, while Get Penetration Resistance is a function

I dont see any difference in how I set it up in the inteface

except that one of them has a return value

and thats why they are different

nevermind

[trim matrix]

That's the difference

[past girder]

I am using random integer in range to play multiple animations but is there a way to make it have higer or lower chance of hitting on of the numbers?

[dawn gazelle]

Your can use bool with weight to do something like this.

As it is right now, it'll be true 50% of the time, put the weight higher, it'll be true more often.

[mortal nacelle]

I'm having difficulties with how to best handle the client replication bits. as far as I can tell, I haven't found a way to coordinate the replication of the actor (SpawnActorFromClass w/ replicated actor) and the variables on the actor (such as ItemID, which will configure the item).

It gets even trickier to write initialization logic if there are multiple variables you need upfront, b/c the order of replication doesn't seem to be guaranteed, right?

for example, i have an ItemID and Count. I need to craft an item text with those such as "10 Gold". If I have separate ItemName and Count variables, then my init logic needs to account for either possible order of arrival.

it could be n^2 number of possibilities to consider

[shadow saddle]

im trying to pick 3 random element from enum without repeat, is there anyway i can do it ?

[mortal nacelle]

@shadow saddle you mean never picking the same element twice in a row?

just keep a variable of the last selection and re-roll if you get the same

[dawn gazelle]

Better yet, keep an array of possibilities and use it as a basis for how big the random number roll should be and remove any values that are chosen.

No re-rolling necessary.

[pulsar moss]

Is there conditional breakpoint in blueprint? I seem to recall seeing it but can't find it now

[tough halo]

is there a builtin macro that can take 2 or more variables and return the first one that is valid?

[maiden wadi]

@tough halo I don't believe so. You could make something like that, but what are you trying to do?

[tough halo]

I found Select object, it does basically what I want

in a written language I can go variable_A ?? variable_B

[covert delta]

you probably shouldn't end up in a situation that requires that. But I guess I would make a function that does a foreach loop over a list of whatevers and returns the first element that is valid.

[maiden wadi]

@tough halo Could work. It doesn't really promise that anything you feed into it would be valid.

[tough halo]

the specific case I'm using it in now is for my bullet hit. I have a niagara system that emits a hitcloud. I also cast the hit actor to an interface that can have more information of what to do with the hit. I cant put a variable in an interface (which is a little weird btw, but whatever), it's only functions. So I have a function that returns a niagara system, but if it's not implemented on whatever I hit I wanna fallback to the default hitcloud

so basically, get the hitcloud from the interface, or use the default hitcloud if we dont get anything from the interface

[fair musk]

Anyone in here good at material blueprints? I am trying to make a decal shading model that does opacity-modulated blending + adds emissive that ignores opacity. I.e. output = input surface x (1-alpha) + base color x alpha + emissive. But it seems that emissive is also getting multiplied by alpha no matter what I try, how do I get around that?

[odd ember]

#graphics materials are not blueprints

[tough halo]

macro

[odd ember]

that will never work

[tough halo]

it works fine

I'm not happy cause I have to cast it back to a niagara system again

I feel I'm going about this the wrong way

the best thing would probably be to define my default in the interface instead of handling it in the bullet blueprint

[odd ember]

it doesn't do anything. in the case of A not being valid, the select node STILL evaluates both

so you'll get a null pointer regardless

[tough halo]

I dont understand

the select will return A if "Select A" is true

if A is null I get B

[maiden wadi]

It's not exactly a ternary statement. Blueprint still checks all pins.

[tough halo]

"checks all pins" means what?

[odd ember]

mean all the pins of the select node get evaluated separately

even if not necessary

[tough halo]

does that matter tho?

[odd ember]

lazy evaluation doesn't exist in blueprint, sadly

yes it does

[tough halo]

are we talking performance penalty or crashes?
