blueprint

[pine trellis]

oh wait I think it works WTF

hold on

[hollow cape]

yeah it should work, that's the way you would do it. When you refactor, think about getting rid of the Get All Actors Of Class

[pine trellis]

yes it works now I had reset the bp on the level, one last question is this method expensive?

[odd ember]

when you refactor
that's some positivist thinking right there

[pine trellis]

I read online saying that get all actors off class is expensive and should only be used in begin play

[odd ember]

it should never be used

[hollow cape]

If at all. I have 0 shipping code that uses it

[odd ember]

the fact that it is expensive doesn't really matter

[rough jay]

what should you use instead

[odd ember]

it's the fact that it creates hacky scenarios that trip you up further along the way

[deft hawk]

Why is OnComponentEndOverlap so delayed/inaccurate?

[hollow cape]

The blueprint communication vid pinned here explains other ways to handle this type of thing

[pine trellis]

well alot of stuff on the market places uses it

[hollow cape]

Doesn't mean it's right

[odd ember]

lmao

[hollow cape]

you should strive to get rid of it in general

[odd ember]

I would never buy any BP off the marketplace

it's a recipe for disaster

[hollow cape]

Every time I've tried to implement a system off the MP, I end up scrapping it. Never works out

[pine trellis]

well how else can someone learn, I learned from looking at code off the marketplace

[odd ember]

that's bad

[pine trellis]

some people even helped me and showed me stuff so its not that bad

[odd ember]

it is bad

[hollow cape]

@deft hawk have you verified there aren't additional debug spheres maybe inside the pillar? You have no conditions as to when the endoverlap should be called (as in, end overlap with specific actors), so there could be more

[odd ember]

it's the blind leading the blind

[hollow cape]

It does at minimum give you an idea of HOW systems can be assembled. Might not be correct, but it is a way to learn. Not the greatest, but it is a way.

[odd ember]

and you could for instance look at the blueprint communication tutorial that is pinned in this very channel and that I asked you to take a look at yesterday

that's how people learn

[hollow cape]

100% on that. There are some fantastic resources here

[pine trellis]

where is it pinned

[odd ember]

in this channel

[pine trellis]

oh I see it

[deft hawk]

@hollow cape There are no extra spheres inside the wall (used wireframe view to confirm)

[odd ember]

@deft hawk have you debugged it?

[deft hawk]

Sorry don't understand what you're asking

[odd ember]

okay let's try like this

get a print string node

and put it where it says Other Comp

[chrome orchid]

hey how would i make a type of player grabbing system like the game gang beasts im not sure what component to use to connect the 2 players

[deft hawk]

@odd ember Yea it's printing the name of the component it's ending overlap with

[odd ember]

that's kind of the point

so is that the component you want it to overlap with?

[deft hawk]

Yes

But it's returning a different end location every time

It's intended to draw the green sphere at the location where it ended overlap

ie. the other side of the wall

[hollow cape]

is this using projectile movement component? traces?

[deft hawk]

Projectile Movement

[hollow cape]

what's your velocity set to

[deft hawk]

3000

Pretty sure it's just the simulation being inaccurate because of speed, but then how can it detect the begin overlap location perfectly every time.

[hollow cape]

you could trace backwards on end overlap theoretically to find the exact other side of the object.

would be hard to account for gravity however

[deft hawk]

I tried that already but it was returning the same inconsistent results. Green circle was getting drawn inside the wall

at various locations

[hollow cape]

is this object a standard cube that's just scaled?

[deft hawk]

Uhhh. possibly

yes

[hollow cape]

just to verify do alt+c and make sure it's not an issue with the collision

[deft hawk]

Collision appears to be fine

[odd ember]

try without using scale

use box extents instead

[hollow cape]

eh I've never had issues with scaled meshes.... I think it's a substepping issue with projectile movement

[deft hawk]

Yea, un-scaling it had no effect. I wonder if it's just the delay from the end overlap event to the DrawDebugSphere

[hollow cape]

no

that won't be it

[odd ember]

I've seen scaling issues before so if nothing else using box extents is playing it safe

[hollow cape]

no kidding? there ya go

[deft hawk]

What is a box extent?

[hollow cape]

That doesn't help here though, as he's just using the end overlap event

[deft hawk]

I also thought it was a sub-stepping issue, but I maxed out all the values and it didn't change anything

[odd ember]

did you tick the box for ccd?

[deft hawk]

I don't think so, where is that?

[odd ember]

search for it

ordinarily it shouldn't be necessary

[deft hawk]

Checked it, same results

This is really weird

[muted dawn]

hey are there any good tutorials for physics based shooting. the bullets are tracers?

[odd ember]

sounds like a question for google

[muted dawn]

oof

alright

i will try at 8am

im trying to replicate something like insurgency's weapon system

almost minimal hud

[rapid token]

How could I make it so if a player stands in a collision, it will repeatedly execute an int + int node then when the player stands out of the collision, it stops. This is all I have right now..

Im guessing I need to use While Loops, I just dont know how to use em..

[pseudo heron]

The while loop doesn't seem too hard

From what I can see and from what I know from lua,
The loop body is what you want to loop and the condition is basically yes or no if you want it looped, and completed im assuming is used after the loop is done, though I've never used it so, I'll go head and try.

[rapid token]

^^^ It says that is an infinite loop... How.. @pseudo heron

[pseudo heron]

Not quite sure.

Usually in lua you'd simply turn off/ change the bool to false and it stops, Assuming this isn't the same it works different, to which I have to test.

[rapid token]

Hmm

Its not infinite since if you leave the collision, it will turn off the loop?

[pseudo heron]

That would make the most sense, it runs solely on if the bool is true

[rapid token]

Or am I not understanding the meaning of Infinite loop

[pseudo heron]

if its false it'll instantly turn off

[rapid token]

Yep, I made it so if you enter the collision, the loop will start then when you leave, the loop will end

[pseudo heron]

in lua it'd be (note: its a coding language)

while true do
print("Test")
end

Of course this would crash you, to which if you wanted to do something until it was off you'd probably instead result to repeat

repeat
print("test")
until boolorwhatever == false

[rapid token]

Yep, I learned a bit of lua years ago

[pseudo heron]

Whats the details of y our bool?

[muted dawn]

doesn't cryengine use lua?

[rapid token]

The default is False

[pseudo heron]

Probably, most games use lua as its easy to code with, pretty sure GTA used it for mods and Saints row used it to make the game

[rapid token]

When I go into the Collison, the Play Viewport crashes and I get the error that its an infinite loop

[pseudo heron]

Hm

OH wiat

[tight schooner]

@rapid token a "while" loop doesn't occur over time. You're asking the machine to loop infinitely in one frame until the condition changes (which is never unless something in the loop itself changes the condition)

if you want to repeatedly check something over time, use a looping timer (Set Timer By Event node) or tick

[pseudo heron]

^

[rapid token]

Im confused..

[pseudo heron]

Basically

it crashes because its printing too fast

I tihnk

[tight schooner]

the loop never changes the condition, therefore the frame hangs

[pseudo heron]

or whatever that means

[rapid token]

But when the player leaves the collision, the condition changes?

[pseudo heron]

It doesn't register that until they actually leave

Try adding a delay

anywhere in the loop

should work

[tight schooner]

delays don't work in loops

[pseudo heron]

wack

[tight schooner]

if you want a loop that occurs over time, you need a looping timer

I don't know what you're trying to achieve, but... maybe you just want a branch node?

condition --> branch --> your two prints

[pseudo heron]

They want something to happen while its in the box

once you leave it stops happening

for example, while in a box apples spawn, while out of it nothing happens

[muted dawn]

btw how can i add weight do certain guns and attachments suck as scope

google gives me wack

[tight schooner]

@rapid token I scrolled and read what you're trying to do. You need to use a node called "Set timer by event". You attach the red wire on that node to a new custom event. You also set the event to loop.

[pseudo heron]

That I cant answer because me myself am new to unreal engine, ish

[rapid token]

WhY DoES WhiLE LoOPs NeeD tO BE sO DiFFicUlT

[pseudo heron]

good question

[tight schooner]

This will cause an event to repeat over time (your int + int, or w/e)

[muted dawn]

set timer by event is the way to go

[rapid token]

They could have made it more simple tho

[pseudo heron]

That makes sense

[muted dawn]

i use it on my stamina system

for add stamina and remove stamina events

[tight schooner]

On collision end, you can Clear Timer by Function Name, or however you want to clear the timer (there are a few ways to do it).

[rapid token]

Let me try what you said

[pseudo heron]

on the topic of repeats, Is there a way to make something repeat until something else is a certain value, pretty vague but for example,
Repeatedly subtracting player max walkspeed until it reaches 190 or something

[tight schooner]

@pseudo heron If you want it to happen all at once, like keep doing math until output = X then you can do a while loop, or a "loop with break". If you want it to happen over time, you need to make some event or function, and use a looping Set Timer node to put it on a periodic repeat

[pseudo heron]

Mmm I can try that

[rapid token]

How is the BP supposed to look? Because I cant get it to work 😂

[odd ember]

use a timer, not a loop

[rapid token]

How should the Blueprint look?

[odd ember]

like the image you posted

except you start a timer

instead of a loop

and get rid of the boolean

[odd ember]

yeah that ^

[rapid token]

Wont work.....

What am I doing wrong?

Wait

[odd ember]

the time is 0

[rapid token]

Got it

Thank you! 😄

[odd ember]

I recommend using GetWorldDeltaSeconds

for anything in world

[rapid token]

Um alright.

[odd ember]

that will roughly approximate one frame

so your value updates each frame

[rapid token]

Oh, alright.

[odd ember]

timers are framerate independent though

[rapid token]

Ah

[orchid osprey]

I m quite new to BP and i m trying to make a progress bar where you hold F and it feels the progress bar but its not working always right
What i m doing wrong and can i make it without tick ?
https://i.imgur.com/UC1DTO8.png

[pseudo heron]

How about

Hm

Probably should just

Put the tick/loop/whatever into the actual part when you press F

and change from tick to loop so you have more control

Tick from what I remember doesn't give a shit about what you want and will keep going on

and i gtg great

cao

[orchid osprey]

What do you mean by in the actual part ?

[pseudo heron]

the point to which you press F

as in the pressed <> thingie

[orchid osprey]

cao thx anyway 🙂

[odd ember]

loops are near instant and don't offer the same time stepping as something like a timer or event tick does

[orchid osprey]

idk what he meant so i m still stuck 😦

[odd ember]

you shouldn't use event tick like that. use a timer that increments a value over time

[orchid osprey]

found out my problem its the delay

[odd ember]

e.g. when you press F you start the timer, when you release F the timer stops/resets

[orchid osprey]

yes everything works but when i add delay to my widget visibility it is not working right

[odd ember]

then... don't?

[orchid osprey]

i want to not vanish instantly when you release F key

i want to be able to see the progres for 1-2 sec

[odd ember]

well like I said use a timer and you'll have more control

or don't and live without the delay

up to you

[orchid osprey]

will this the same setup work with timer

[odd ember]

you will have to change your setup slightly to accommodate for the timer

it replaces the tick functionality

[orchid osprey]

so i just need to change the tick nothing else ?

[odd ember]

.... no

[orchid osprey]

lol

[odd ember]

I said it replaces the function of the tick

[orchid osprey]

ok i will search bit more on google 🙂

[odd ember]

yes pls

[rapid token]

@odd ember Hey, for some reason the loop is continuing after I leave the collision. Im pretty sure it was working before, I dont know why it isnt now

[odd ember]

you have to turn it off manually

[rapid token]

What?

[odd ember]

there is a handle at the other end of the node

[rapid token]

Like that?

[odd ember]

no

[rapid token]

Lol

[dawn gazelle]

You have the timer set to looping. It will always fire one activated. Promote the return value on the timer to a variable, and then on the "EndOverlap" event clear and invalidate the timer.

[odd ember]

there you go

[rapid token]

Thank you.

[dawn gazelle]

I know in my example there it shows ActorEndOverlap, but you should have ComponentEndOverlap or something 😛

[rapid token]

It works, thank you! 🙂

[trim matrix]

I feel like this is easy but I can't figure it out

Anyone know how to reset jump animation in the air?

[rapid token]

I have not messed with animations yet so im not sure, sorry.

[odd ember]

#animation

[trim matrix]

Nah there should be a blueprint code for this

[odd ember]

well you're wrong

[trim matrix]

?

There is definitely a way to do this in blueprints

[odd ember]

#animation is where you should ask your question

[trim matrix]

There are multiple places I can ask this question

[timber cloak]

he is right, since animation is better place for that question

because not everyone in BP knows what's animation about

[odd ember]

you ask once, in one channel as per #old-rules

[trim matrix]

And I only asked once, in this channel.

[odd ember]

and I am telling you that #animation is the correct channel

so perhaps instead of arguing

[trim matrix]

And I am telling you There's multiple places I can ask it.

[odd ember]

you could delete your question here and ask there instead

instead of insisting on getting blood from a stone

[timber cloak]

lol, reminds me of an item called BloodStone in Dota.

[trim matrix]

If you can't answer the question don't respond to it. It's that simple

[odd ember]

I did answer the question

[trim matrix]

blocked

[odd ember]

there isn't a way to do this in BP

[timber cloak]

what's quickest way to identify which character gets a String type Variable? not Print String, please.

[odd ember]

how do you mean?

[timber cloak]

yup, like how, please

[odd ember]

no I mean I didn't get your question

[timber cloak]

uh sorry

here's the thing, i already set up an enum for all characters (like previously we talked about), now i want to give "String" type of variable to each enum variable.

so, i want to see the results of what is being made

[odd ember]

enums have a ToString function

or node

so the conversion should be easy

[timber cloak]

uh, i will check that. Thanks

um, not that.

[dawn gazelle]

Perhaps something like this, but with your specific enum is what you're trying to accomplish?

[timber cloak]

I will be more specific, sorry.

[dawn gazelle]

so you can set a variable based on what enum was selected?

[timber cloak]

i am storing an array of strings. Example, my Enum is called "job", and my string is called "1st fruits" and "2nd fruits". What I am trying to do is, each enum gets the same "1st fruits", and then the same each gets different "2nd fruits".

The reason it is being an array of String is because, once any of the fruits being delivered, no one can get it second time.

[odd ember]

I still have no idea what you're trying to do honestly

[timber cloak]

it is kind of "guessing" which fruits you have.

[odd ember]

like you want to use an enum just once it sounds like

[timber cloak]

enum already settled.

https://imgur.com/a/0HbM66y

is it confusing?

the 2nd fruit is easy, once you use "remove index" after 1st fruit

[timber cloak]

well, i am thinking of array due to removing the 1st fruit.

so, how do i check which player gets which string type variable?

not Print string

[dawn gazelle]

So you're already assigning an array of strings to the player, correct?

or just a single string of a specific fruit?

[timber cloak]

yes, correct

um wait, this is actually run on game mode, since game mode decides who to give.

player has 0 choice

gamemode will randomly loop through to give them.

so the string stays with GameMode only, unless i am mistaken.

[dawn gazelle]

You are the one in control of where variables are being stored. If all you've done is created an enum with a list of jobs, and a couple of arrays with strings in them, you're still a ways away from assigning a player any fruit.

[timber cloak]

Enum variable for player's job is assigned. And yes, fruit array is made too

[dawn gazelle]

Ok, where are you assigning that job? Which blueprint are you storing the variable for the player?

[timber cloak]

just need a way to see whether my "assigned fruits" BP code are given properly. Need a way to debug/see the result.

i assigned the job in ThirdPersonCharacter class, exposed on spawn.

[dawn gazelle]

ok cool

[timber cloak]

so how to debug/see the fruit String results? Just would like to know whether i am doing it correctly or wrongly.

[dawn gazelle]

Ok... I think I get what you're saying... You want to see what is in the player's inventory.

Why doesn't print string work for you tho?

You want a widget or something displayed on screen?

[timber cloak]

the way i did was, before that "for each loop", i have another "for each loop" on enum array.

print string can't see directly on what/which players has which fruit.

"for each loop" on enum job -> wire to "for each loop" on string fruit. I think i am doing it wrongly maybe.

which is why need to see/debug.

[timber cloak]

yeah anything will do.

[dawn gazelle]

This is a multiplayer game I take it?

[timber cloak]

yup, nothing serious. Only to learn the ropes of blueprint and understand something new

no need to be accurately replicated, just simply multicast will do

[dawn gazelle]

On the ThirdPersonCharacter blueprint, you can do something like this, assuming again you've stored the fruit in an array on the ThirdPersonCharacter blueprint. Each client you can press page up on and then it'll display their own specific array of fruits.

This should be sufficient for checking whether or not your players are getting the appropriate fruit.

[timber cloak]

uh, i can see the results now

all blank lol. Means i am doing it wrongly

thanks!

[idle gust]

Regarding the gameplay ability system, I'm trying to figure out how to execute code on the simulated proxy. But no matter what I try, I can only get code to execute on the auto proxy and the server. I'm currently working in the event graph of a UGameplayAbility

Can anyone give me a suggestion on how I can get a sim proxy to execute code on an auto proxy gameplay ability activation?

[snow halo]

hmm weird brain fart

is there any way to do a validated get in bp on an array to get a ref to an element?

if that index is out of the array size i don't wanna mess with it obvs

[hollow cape]

is valid index

[snow halo]

but that just returns a bool and the get would still run since it's "pure"

so i'd get some kind of null error out of size

i'm trying to avoid even trying to get if the index doesn't exist in the array

[hollow cape]

you can use a select

assuming you aren't wanting to use a branch

[snow halo]

im ok with a branch!

i just wanna make sure GET doesn't try and get at all if the index doesn't exist in the array

in this hypothetical example, the get i assume would still return a null error

even though i'm not doing anything with the element because of the branch

[hollow cape]

that wouldn't return null

[snow halo]

am i wrong?

[hollow cape]

the get wouldn't run unless the branch was true

easy way to tes

test*

[snow halo]

hmm ok i thought because the get doesn't have an exec input it would run regardless of the branch

ya i just plug 100000000 into the get

and see what happens?

hehe

[hollow cape]

make sure whatever number you hardcode into the get to test, you put the same number into the is valid index

[snow halo]

precis

yup

ya no errors so i guess i'll move on, but always trying to be careful of null errors clogging things up

[hollow cape]

yep

[tight schooner]

@snow halo kind of an academic point but you can also do a length check. If array length isn't greater than whatever... etc

but I haven't had problems with Is Valid Index

[snow halo]

ah nice one!

sweet ya. I actually just opted to switch to a map so i can avoid the issue all-together since Find has a check built in

think it's a win win as long as maps are ok with having thousands of pairs : /

int - struct

[tight schooner]

I've yet to play with those...

I suppose my game doesn't have an inventory system or anything

[snow halo]

think if you know you don't need to iterate something sequentially (might as well use an array then) they're a great option

v useful for picking things out without concern of re-ordering etc

[mortal nacelle]

Regarding blueprint replicated array of a struct. Is it possible to have a race condition between the OnRep callback and the data being fully replicated?

I have an array of inventory item structs. When I get the OnRep callback and then read a certain field, I’m always getting the default value instead of the item’s correct value

I’m looking at the field in the editor during runtime, it’s showing the value is replicating correctly. So I wonder if this is a race condition?

What’s strange is that only one specific field is having the issue (item size). The item icon is replicating correctly every time.

[muted dawn]

Hi, I need help adding a delay to my stamina regeneration from when i release my button does anyone know how to do this?

adding a delay doesnt work it makes it continue draining stamina after the for the value i have

[stuck hedge]

I have never seen this before... Take this scenario: Map A has 3 copies of Actor B on it. On startup, you get all actors of class B and it returns the 3 actors. On Map C, you also place 3 copies of Actor B on it, and on startup you get all actors of Class B and it returns nothing.

anyone ever seen anything like that at all?

if a map is large, could it not load all the placed actors before the game mode fires off its begin play?

[broken roost]

Hello, does anybody know why this doesnt work? So basically i've got macros which returns me an object but it doesnt work properly, but if i just past the code that in it and run it - everything works fine. what do i do wrong?

[maiden wadi]

@stuck hedge It's possible, but I was under the impression that anything in a map, IE placed in editor, was all loaded before game mode's beginplay. I could very well be mistaken though.

[stuck hedge]

I just found out that someone had 2 maps with the same name. So I think the editor was confused on what map to load

[maiden wadi]

Splat

On a side note. If you are on 4.26, you can load maps by soft object now!

@broken roost So basically if you have the interface call in a macro, it doesn't run correctly? Have you checked validity inside of the macro and out?

For both the GameState and the returned pointer from the interface.

[broken roost]

I ran through debug and it seems to get everything it needs

Now i see. the thing is that i do multiplayer project and i forgot to replicate the object))

[latent arch]

Hey all Gd Mornin 🙂

i have some more vector math / world transforms to do 😄

anyone got some idea how i can translate a hit location to its position on the hit objects bounding box? 🙂

so like it makes a point on the plane of the bounding box it hit

essentially what this is showing, but im having errors translating ehehe

trying something like this at the moment for the first point, it "works" but if the object is rotated the impact point is not where the trace hits

Good

Bad

lol 🙂

[muted dawn]

can someone plz explain to me how to delay my stamina from recharging after i let go of shift

this

[worthy tendon]

you can set initial delay for the "Set Timer by Event" node. just open the advanced section of that node.

[muted dawn]

oh

@worthy tendon thx

[cunning sigil]

Any way to get my actor current Y axis and add value to it with blueprints?
so for example i wanna get the current Y and push it another 5m up

[maiden wadi]

@cunning sigil Like, their location, or?

[worn nebula]

What's a good way to tell if the player is standing still?

[maiden wadi]

@worn nebula Usually velocity.

[worn nebula]

So like use a Get Velocity and if it all = 0, return true?

[worthy tendon]

if the velocity is near zero. you might want to check if player is sitting or standing as well

[maiden wadi]

If ( GetVelocity->GetVectorLength < 0.5 ) Character is probably standing still

[cunning sigil]

Yes location i mean

I wanna make the car go up 5m on clicking K

[worn nebula]

Nice one, thank you guys

[maiden wadi]

@cunning sigil Up or sideways? You said Y earlier. That's left and right in traditional Unreal. Z would be up and down.

[cunning sigil]

oh sorry yes i mean up

[maiden wadi]

Either way, Basically SetActorLocation to (GetActorLocation+DistanceToMove)

@cunning sigil Can't send images right now with the world wide Google issue apparently.. but yeah. Try what I posted above. Should just be GetActorLocation, drag off that and Vector+Vector. Do +500 to Z on that node, and plug that into a SetActorLocation.

[grizzled pivot]

just use an linetrace https://docs.unrealengine.com/en-US/InteractiveExperiences/Tracing/Overview/index.html

[primal smelt]

I updated Unreal for the first time in ages and noticed that I no longer get a live read-out on the event graph of a blueprint during runtime. Was this a removed feature or something I just need to re-enable? I don't want to have to add a break-point and slowly frame skip to what I want to see, there are some things I can tell are amiss at a glance.

Basically talking about seeing the routes light-up, anyone know how to enable this?

[latent arch]

Can anyone see by looking if these vectors are world space or local space? i want them to be local to the object that's tracing towards the hit object

[short coral]

Hello , i'm trying to create a spline wall except i want it to be editable while in game and not in the editor , can anyone here give me any ideas ? I'm kinda stumped

[latent arch]

i ask because as you can see it is placing more trace points on the players side than the tracers side. Id like is so theres more trace points on the side of the tracer

[primal smelt]

When you say editable in-game, what is your intention?

[short coral]

@primal smelt Its a building system of sort , i want the player to have a wall that he can drag and extend instead of placing one mesh after the other to make a long wall if that makes any sense to you

[primal smelt]

For having it editable in-game only you'd need to build the spline in the construction script. I recommend building a vector array and then using a for loop (it might need to be a for each loop, I forget) to add the spline point for each index. You won't see the spline generated until run-time.

[latent arch]

i got it sorted 😄

[primal smelt]

I'm not sure how you would get the player to manipulate them in-game, maybe have a mesh generated at each spline point that the player could interact with via line/box trace. When the player interacts with it you could use "Find input key closest to world location" to determine which spline point they wish to manipulate. You could then set the spline point at player character's location (if they are physically moving up to it, "grabbing" it and moving away for example) or at location of the player's mouse cursor.

[short coral]

Yeah for me its the player handling is that's a bit ambiguous i already have the first part down and i thought of it too its just i'm not sure how to go about grabbing it kind of so that the player uses it

[prisma pumice]

What is the world context object? I want to know about role of this, and how I can get it in blueprint, but... When I'm searching about it, no one seems want to tell about this. What I have to is just link to this node from some actor reference in the world?

[zinc portal]

I want a system to play audio but (calling this via an interface) not be available for another audio call until the line is done.
I made a boolean (CAWS_Available) and when command is called this value is 1st checked, if true it is then set false, sound played, delays, set the boolean to true.
In my head it should work fine but I still get repetitive overlapping sound clips.

my blueprint can be seen here. (The variable is now under the player controller as I was trouble shooting it)

same but just image

[odd ember]

if this is for something like dialogue

you should use a state on the dialogue engine to check against

[zinc portal]

sort of, it is a warning alert from flight computer.

but I get same exact issue with a warning sound so, I don't feel that this is dialogue (or even audio) related per se.

[odd ember]

messing with bools like you have is a surefire way to get tripped up

well dialogue in the sense of you don't want one line to overlap another line

but up to you

it's your problem not mine

[zinc portal]

ah ok. I have no clue what dialogue engine is - so was hoping avoiding new can of worms right now 😛

[odd ember]

you want a system that is airtight first

and then let dialogue play through that system

the system itself should know when it is playing a dialogue

it should not be triggered by the dialogue line itself

[zinc portal]

I appreciate the help. I guess I need to bite the bullet and look into dialogue stuff.

[odd ember]

then later you could also potentially fix it it up to queue up dialogue lines

like I said it's not so much dialogue

as it is creating a dialogue engine

[zinc portal]

ok, cool. Thanks. learning is fun.

[harsh coral]

Hey guys.

I have an issue, I need to render a static mehs turntable, the mesh is inside a blueprint.
Now, when I add the bluebrint to a squencer it looks alright in the viewport, but as soon as I try to export it as an image sequence, it becomes invisible after 22 frames...

Is there a setting somewhere inside the blueprint I need to check, so it runs for the lengthe of the whole sequence?

[spice ibex]

Is it possible to send backspace or delete key input using this node?

[harsh coral]

Ha, found it

Right click, convert to spawnable...

[zinc portal]

Still calling for help for why this wouldn’t work. I appreciate CranzEstebogen comments but for now would just need a simple solution.

[odd ember]

is the delay long enough to cover your sound?

[gusty shuttle]

Quick one, what's the best way to get my widget interaction from my class actor (motion controller) from a ForEachLoopWithBreak?

Seems like the object ref is not allowing me to, why is this?

nvm, I had to refresh the node

[shrewd condor]

Have the call in editor functions/events been deprecated in UE 4.26 ?

[blazing atlas]

Thanks for this by the way! Good work around and now my pause screens have lovely animations again 👍

[grizzled rain]

My pleasure.

[prisma pumice]

Yes. It's ok if linking with any pawn, actor, or anything in the level. To be precise, inthe world. "world context object" means, anything that could get world through object->GetWorld().

[prisma pumice]

Maybe not. my project in my work is switched from 4.25. But it works right.

[narrow bear]

I had to re-enable the editor scripting utilities plugin, maybe that's screwing with ya?

[zinc portal]

plenty long.

[gusty shuttle]

When using a Widget component, when the actor gets destroyed, does it auto RemoveFromParent?
Or every time an actor with the widget component is spawned, does it AddToViewport

Or does it just layer ontop every time it's spawned?

[rough jay]

i think destroy actor destroys the whole actor

[past girder]

hi, i am trying to import a animation but get this error failed to import /.... .failed to create asset

[cold moss]

So I had a question about umg is it possible to program an admin command to change a umg widget for a specific player other than your self

[dawn gazelle]

Sure. You would need to get a reference to the specific player controller you're wanting to change.

[cold moss]

How would one go about doing that

[dawn gazelle]

You'd have to store a reference to all player controllers and have some way of referencing that specific one. Like their player name or something like that. You can create a map of the names to the player controllers, this would then be able to do a find on the map for the specific player, which would then return their player controller.

[cold moss]

I'm assuming this would require a switch on authority to get the server version of that player controller?

[dawn gazelle]

You're going to need to do an RPC as clients do not have reference to other player controllers, only their own. I imagine you're going to be doing something through the UMG to trigger the event on the first client to change the UMG on the second. So the first client would have their UMG run an event on their player controller which triggers the RPC to the server, which can then look up the reference to all player controllers (probably best to store in game mode or game state), which can then trigger an event on the receiving client's player controller, which can update their UMG.

[tidal willow]

Is there a fixed update where I can run something 20 times instead of the frame rate

[dawn gazelle]

@white lynx This is a third party plugin you're looking for support for. You may want to try contacting the plugin developer as from what I can see in the source of the plugin, it doesn't support having more than one extension shown at once.

ah, very good. Only saw the pipes in the source, nothing about semicolons.

@tidal willow Would a timer suffice?

[tidal willow]

I was just thinking that updating stuff like the door position shouldn't happen thousands of times in a frame to the clients, only 20

for updating the doors

thats what I meant lol, I meant thousands of time a second*

depending on the FPS

but

whatever lol

No

it should be lerped to the new position to be smooth

instead of sending hundreds of packets

The door position is changed by your mouse

[lusty shard]

less is more

[tidal willow]

you move the mouse right -> the door opens a little bit

move it left and it closes a little bit

yank it across the desk and the door swings open

:)

[lusty shard]

how do i put a value into the Parent Socket?

it wont let me type a value as I expected

or select one with a dropper

doesnt seem to be a way..

trying to attach this static mesh rock to the spine

[dawn gazelle]

@tidal willow So you could potentially use a timer like I showed above, and the event from the timer can call your RPC. When they stop trying to manipulate the door, you need to invalidate the timer.

[tidal willow]

Okay thanks! I'll try to make it work

The door is a little bit complicated so i'll have to figure it out lol

[faint pasture]

@tidal willow use a timeline dude lol

Also why is door update code in the character?

[tidal willow]

I'm not exerperienced with timelines at all so I don't know how that would help

it's in the character because it's multiplayer

the door doesn't open it self
the player opens the door

[faint pasture]

Is a door the only thing a player ever interacts with?

[tidal willow]

With that button, yes, i'm working on an item pickup system too

but I decided I should change this so it only updates 20 tps on the server

if you can't tell I'm a beginner 😆

[faint pasture]

K you'll want to get this right before you get a giant mess on your hands.

Start with making a door bp that can update itself (with a timeline) and in the character either cast the line trace hit actor to door to activate it (poor practice) or make an Interaction interface and implement it on the door.

[tidal willow]

That's what I tried at first
It wouldn't work with multiplayer cause I couldn't send server events because clients don't control the door, the door (server) does but the players clients control their clients (and not the door)

[faint pasture]

For multiplayer you'll need to use a run on server event between the line trace and the interaction with the door.

[faint pasture]

You send the server event within the character to trigger the door. So it'd be like input, line trace, server event, door interaction.

[tidal willow]

so this stuff should be in the door?

[swift dome]

I have a media player variable in a blueprint, i have a button in a separate blueprint, how to stop the media player on the button click

For the start how to access the media player element in the graph where i have the button

[odd ember]

there's a pinned post

in this channel

for blueprint communication

I recommend going through that video

[swift dome]

ok thanks

i could make a media player variable and set a default value as the player i wanted

Now i am trying to figure out how to stop a running instance of media player on a button press

[forest sable]

can somebody enlighten me

i have this code

[narrow bear]

Empty input array?

[forest sable]

The bottoms prints fine but the top doesn't print even once

[narrow bear]

Put a print before the loop, that prints the length of the array

[forest sable]

I did it prints fine too

[narrow bear]

I'm sure it prints, but do a print of the length of the array

Ref -> Length

If it doesn't print anything in the loop body, it just means there's nothing there to loop over, empty array

[forest sable]

ok one second

It is printing 0 at all conditions

meaning it prints 0 when it's not supposed to

[narrow bear]

So the problem lies before you call that function. Whatever is calling that function, is passing an empty array

[forest sable]

it's worth mentioning that another For each loop Passes the Execution through to this for Each Loop

[zinc portal]

The boolean thing didn’t work. I don’t know why.

But setting the sound concurrency did. Short test here. The alert is too easily triggered (and it says now collision twice on the clip, on purpose).

hi guys is there a way to make an event tick start working when you press a button?

what im trying to do is make runner and i use the event tick so you dont have to push a button to move forwards, and now i make menu screen for it

but when i play it starts moving and i was wondering how ot make it only activate when i press a button

[devout pine]

If you are bored with tutorials: "how to blueprint" I made one "how not to" https://youtu.be/iYVkonpzMbI

[tidal willow]

hahah! Glad I already know how to program

[stray island]

Dont make me jealous

[tidal willow]

Just learn then?

lol

[stray island]

No, blueprint is fine by me , still jealous tho

Because I’m an artist in first place

[tidal willow]

I'm not lmao

I have programmer art

[stray island]

C++?

[tidal willow]

programmer art == shitty art

the best art i've made was my first completed game

[stray island]

What language u used

[tidal willow]

it was with godot the first game

But i know c++ c#, java, some python as well

But I'm best with c#

[stray island]

Oh , python and c++ are ones i wish i know

[tidal willow]

then learn them! haha

You can't just wish to learn it :p

[stray island]

No its like i have a dream car but i know i wont drive it

So i stick with my working car

[tidal willow]

i dont get it but ok

you've already convinced yourself you'll never do it so

[stray island]

I meant blueprint is doing the job decently well

[tidal willow]

you don't truely wish you knew them then

[tight schooner]

@boreal helm there's a node called Set Actor Tick Enable

you can disable the tick on an actor class by default in the Class Settings

and then enable it explicitly with that node

[stray island]

How long of experience u have ? Learning them

[tidal willow]

about a year to be honest

i still learn stuff like all the time

I mean unreal engine has been a hella ride for the past two days

[stray island]

Oh, i did mess with them long ago with unity as I remember but blueprints made me leave programming

[tidal willow]

Don't get yourself wrong, blueprints is still programming

Writing instructions for the game to run

[tight schooner]

@swift dome There are a lot of ways and it's specific to the "architecture" of your project. If there are only one of those BPs spawned in the world, your widget can use "Get an actor of class" e.g.

[stray island]

i know they are called visual programming but its engine specific so i dont consider them programming

[stray island]

sorry for the chat while your helping people hehe

[tight schooner]

I think BP is a visual scripting language

I'm not a programmer so I don't have a fine sense of what separates programming from scripting

[tidal willow]

I eat Taiwanese food, but since it's not like every food in the world, I don't consider it eating @stray island

:p

[tight schooner]

@stray island no problem 🙂

[tidal willow]

@tight schooner scripting language and programming language do the same thing
They're just instructions

They're the same thing

[stray island]

Ya maybe bp is considered scripting not programming

I meant id consider it programming if it was pure and can work out of your engine too

[dawn gazelle]

Think of it this way: A script to an actor, is a means of knowing what to do. An author had to write the script in order to tell the Actors what to do. Anyone who writes something that tells someone what to do is effectively "programming" them to do certain things. 😛

[swift dome]

Thanks, ill try searching about getting the actor of a class

i am a complete noob in unreal

[stray island]

But i can call ios (shorcuts app) programming , or android macro apps programming that way

[tight schooner]

"program" is a word that exists outside of computer science (e.g. https://en.wikipedia.org/wiki/Program_music) so...

[dawn gazelle]

Sure you could. Just like entering =SUM(5+4) is programming in Excel.

[stray island]

I don’t disagree with the meaning , I understand the meaning but , in real world i think a programmer is who knows programming languages

[dawn gazelle]

Nah a programmer is someone who has a sufficient level of Google-Fu.

XD

[tidal willow]

truth

[stray island]

A programmer can make robots that will ruin our future i dont think u can do it with blueprints

[dawn gazelle]

You absolutely could

[odd ember]

I don't think you realize how boundless programming is

[dawn gazelle]

UE4 can make calls outside of the engine with blueprints. I can make something in UE4 that communicates with a RaspberryPI that can control servos and motors.

[odd ember]

there's nothing stopping you from making a self replicating actor in BP

[stray island]

Really , i didnt know that

[trim matrix]

I didnt know that either lmao

Thats dope

[dawn gazelle]

Also, I can program in Perl, PHP, C++, C#, Javascript... But I don't know the languages in their entirety. Does that make me any less a programmer? I'm able to do things with these languages that a lot of people wouldn't even begin to comprehend as they don't know anything about programming.

[stray island]

Yeah i feel proud of my self rn , tesla should hire me

[dawn gazelle]

Blueprints makes programming hella easy - I find it way more intuitive, and works way better with my brain then trying to scan lines of code.

[trim matrix]

My mans speaking straight facts over here

[stray island]

Okay but it will always be limited compared to real programming tho

[tidal willow]

Honestly as a programmer, blueprints are hard af to read for me, but i'm slowly getting used to it
The reason I use it cause I love how intergrated into the engine it is

[odd ember]

the true mark of a programmer is the engineering mindset

[tidal willow]

I'm not used to seeing stuff like this

[stray island]

Blender shader Nodes or rhinos modeling uses such interface im kinda used to that look

[odd ember]

(as in, even if you don't know how write it in a specific language, you know what needs to happen in order to execute)

[hollow drift]

I have a double click function whereby when i double click i want to finish a animation immediately and set it to the end. problem is i cannot use the output finished as it counts my amount of rotations. So if user double clicks he will get 1 more additional rotation which i dont want. Can I somehow send two exe, one to set new time and one down the line to my normal program? Also i have to use play from start

found a workaround. just killed off animation with multiply by 0 and a well placed set

[dawn gazelle]

@stray island That is true, but that could also be said for other programming languages - if you aren't provided with certain functionality from the language itself, you typically have to program it in to the language at a lower level to get it. Some languages are more robust or feature rich out of the gate than others. Blueprint can be fairly well expanded through UE4's C++, though I know there are limitations on what Blueprints can ultimately support (like no double precision floats currently). Ultimately, scripting and programming is usually based upon whether something needs to be compiled or not in order to be executed, and in Blueprint's case, it's not required to be compiled, so technically speaking, it is scripting, but don't think that it makes you any less of a programmer as you're still learning and using concepts that text-based programmers need to use as well, you're just not typing out lines of code and can't interact with some of the lower level functions of the engine.

[stray island]

Well , thanks for comparisons , it gave me more confidence as a blueprinter , blueprints has high potential, but its potential is dependent on the engines potential, the more powerful unreal engine gets , the better blueprints are

The luckier part of being a language programmer is that u can improve beyond the unreal engine level

[trim matrix]

Is there a good way to skew an object in UE4?

[odd ember]

export it into blender, skew it, reimport

but also not a blueprint question

[trim matrix]

I meant in blueprint :p

[odd ember]

then no

[trim matrix]

Alright thanks. I can just make different meshes haha

[odd ember]

at least not until epic exposes tools for meshes

[dawn gazelle]

I wouldn't say that - again, you are learning and using concepts that text-based languages use as well. So even with Blueprints you can improve beyond the unreal engine. Once you've learned a concept in blueprint, you can probably figure out how to, or at least how to look up, doing something similar in a different language.

there's a find look at rotation math node you can use

[hollow drift]

how can i see what the values are from a generated map?

[dawn gazelle]

?

[hollow drift]

ty

[lean compass]

Im trying to get the player speed using a get velocity and a vector length and then print it but its not working

i dont know why this isnt working

[dawn gazelle]

Are you sure your Get Speed function is being called?

[hollow drift]

@dawn gazelle thank you, forgot to plug this in, faceclap

[lean compass]

wut

OOOH I HAVE TO CALL IT

my bad

thx

[dawn gazelle]

😄

[lean compass]

when should i call the function?

[dawn gazelle]

When do you want to see the speed?

[lean compass]

ok wait i think i got it i think i know where to call it

[unkempt granite]

Is your get speed function just returning the vector length of their velocity? If so, you could just make it a pure function and plug that straight into the string, and you won't need to call it.

[lean compass]

ok

whats a pure function

i mean i use these ones

oh yeah and when the player is standing still i want to recharge a battery

[dawn gazelle]

When you have a function selected, you'll have an option to make it pure. These functions can be run without hooking up into the execution path.

[lean compass]

oooh

[dawn gazelle]

Then it can appear like this

[unkempt granite]

Yup, what Datura said lol

[lean compass]

thank you ima see if this is gonna work

[unkempt granite]

So if you just need to get the speed value, it's probably more efficient to use a pure function

[lean compass]

unreal engine hates me and its not appearing

[dawn gazelle]

You need to create a return value on your function

And create an output

[lean compass]

oh ok

[dawn gazelle]

Doing this as well, you don't really need to set a variable anywhere in your function.

Just plug in the value to the return node.

[lean compass]

this is starting to make more sense now im pretty sure i did it

ayo yall wont believe this it didnt work

[odd ember]

because it's not hooked up?

[lean compass]

wait

hol up

nope still didnt work

[odd ember]

well if where you hooked it up never gets called...

[lean compass]

OOOHH

i stg i take a 3 month break from unreal and ive gone fuckin dumb lol

ok now it works thank you guys so much

hey how do i use this clamp node its not working

basically everytime you stay still its going to add more battery level but its causing a infinite loop

[swift dome]

When I close the media player, the video closes however; the last frame of the video still remains on the plane, how to clear it?

[lean compass]

also this is the code to refill the battery

maybe i should add a delay

it did not fix it

i tried adding this and the hooking the ce to the event tick and it fixed nothing'

[dawn gazelle]

I would set up a timer that ticks every second that checks whether the player is moving or not, and if so, add the battery life.

Generally I avoid while loops like that, unless you know they are only going to exec a few times. Don't quote me on this, but I think they need to have something within the loop that would change the boolean to false as well to prevent infinite errors.

[trail flame]

Hello. How can I use 6 images as a skybox? must I first use an external program to generate an equirectangular projection from my cubemap first?

is there any easy way of just getting my 6 image cubemap to work? :(

[hollow cape]

afaik you need to create the cubemap in an external program

@trail flame

[trail flame]

that's really stupid

thanks tho

[hollow cape]

I mean, not really? Everything requires a certain format to function. This is the format that is required to function

[trail flame]

1. equirectangular projections have distortion around the poles, which I'd like to avoid
2. cubemapping is an extremely well established way of creating a sky texture
3. it's like 6 calls in OpenGL to use a skybox lol (granted that doesn't take lighting into account, so I can understand why a skysphere is different, but still - there's no reason to just not support classic skyboxes at all)

wound up just using this https://360toolkit.co/convert-cubemap-to-spherical-equirectangular

thanks for the help tho

sorry if I came across as rude - I've just been trying to figure this out for like an hour and a half and I was becoming increasingly more and more frustrated lol

nothing personal

[sand glade]

So my player has a capsule. The collision type for this capsule is 'PlayerBlock'. I have it set to ignore everything except WorldStatic. I then have an Actor that has only a box collision. This box's collision type is WorldStatic. It ignores everything but blocks on 'PlayerBlock'.

But the player is still able to walk through it. The interesting part is if I set the blocking actor to overlap for 'PlayerBlock' instead, it generates overlap event. Then changing it back to block nothing happens. I'm kind of baffled as to why this isn't working.

[vast lion]

Where is a sky mesh dome?

Can't seem to find it?

[dark crow]

You mean the Static Mesh of the base UE4 Sky?

[vast lion]

[stray island]

can i rotate the top view in editor 90 degrees

Instead of rotating my world

[dark crow]

Engine / EngineSky / SM_SkySphere

It's Engine content so if you can't see, check it in the View Options in the Content Browser

[abstract summit]

how to make sure not to modify a timeline already in use

cause sometin i create timeline and that mody another timeline in another blueprint : [

[vast lion]

@dark crow thanks

Do sky materials only work on that mesh?

[tight schooner]

@abstract summit not sure what you mean, but you can look into "curve assets" if you want a fixed thing that exists outside of a BP class

[dark crow]

In theory Materials work on anything, but expect weird results if used outside what they're intended to be used for

[opal marsh]

I am new to blueprint and am trying to test if a socket is rotated too far behind the player mesh. I got it to work for forwards but cant seem to get the reverse to work. Heres the working portion but changing the value isnt working, or other ideas I had. Anyone have any thoughts?

[scenic scroll]

how can i make the force be relative to the object instead of to the world?

the object is supposedly inheriting the rotation of another object but instead of moving along the axis it should it's just moving along the world's axis

[molten gate]

@scenic scroll are you familiar with what it means to get the actors Up / Forward / Right vectors?

[scenic scroll]

i'm sorry i'm not, could you explain / link a vid?

[molten gate]

https://www.youtube.com/watch?v=M3wvhvrXrDI Matthew Wadstein to the rescue as always

I'd recommend watching this one and his "get right vector" and "get up vector" ones all the way through since you're going to use those nodes a lot when programming

[scenic scroll]

thanks a lot! i actually figured it out right now when i looked it up in UE4, its all working good now! :D

now my star destroyer engines emanate spheres in the right direction

[neon sorrel]

Is there any way to detect right / left click in a widget?

Not sure if this should go in #umg or not

[dawn gazelle]

On a button or just anywhere on a widget?

[neon sorrel]

If I can in a button. I was trying to detect left click but for some odd reason when I spawn my widget it wont detect it even if the user is clicking it. 🤔

[dawn gazelle]

Just to make sure, when you created your button, you created the "On Clicked" event for it within the widget, yes?

[neon sorrel]

Yeah of course, that was the first thing I did lol

Ive done it before with other buttons, just for some reason it doesnt trigger with this for some reason

Could be theres something on top of it?

[dawn gazelle]

Yes, or the button could be disabled.

Like, text on top of it should be set to "non-hit testable"

Same with images and what have you.

[neon sorrel]

Hmm, alright ill take a look at that and see if changing order maybe fixes it

[dawn gazelle]

You can override the On mouse button down function for a widget that can then detect specific mouse events. This example can let you right-click on a widget even without a button. Just make sure all paths out of it have the return node set with handled.

[neon sorrel]

I tried playing around with that yeah, I just wasnt sure what the inputs and such there were for

I think I get it now

[mortal nacelle]

any recommendations how to find the actor who triggered a callback if you are listening for it on many actors in the same place?

Hey Ponty!

Does anyone know how to make it so in a Text in a Widget only some of the Text is binded? Such as the text says "You have 0 kills" but only the 0 is binded?

[rapid token]

@solar sonnet Btw your videos inspired me to start learning UE4 again as the last few times I tried, I gave up quickly. But when you started your game, "Punch a Bunch", you were just a beginner and I seen how fast you learned and how well you were doing as a beginner which really inspired me so thank you.

[gray ermine]

Hey, I'm a bit new to Unreal coming from Unity. I wonder if someone can share how the onclick events work? I have a blueprint reacting to this with a top actor and some actors under it. They are all grouped. Is there an easy way to get all objects to react to mouse click without merging the meshes? So they all share one hit box?

[rapid token]

I may be completely wrong as I am just a beginner but you can try using a Box Trigger and put the OnClick Events on that then put the Box Trigger around the objects. (I hope I answered the question correctly and did not misread your issue)

[gray ermine]

ok thanks I'll try it

[rapid token]

Wait

I am wrong haha

[gray ermine]

?

[rapid token]

They are for Overlap events

[gray ermine]

ah

in Unity it is the collision box

[rapid token]

You can try increasing the collision box in one of the objects or create a new actor with just a collision box and set the OnClick Events in there then put the actor/collision box around your objects.

[gray ermine]

Yeah I guess

I just got confused

[rapid token]

@dawn gazelle Thanks, it works perfect!

Hey, if i want current timestamp in miliseconds (Date and time) i though it was the UTC Now. but it only gives current time in miliseconds and not as a timestamp
Any other nodes i could use or do i need to calculate it my self?

[tight schooner]

There's a node called "Now" and some others I can't recall...

Get Real Time or something

[trim matrix]

the now is like UTC Now node, the miliseconds and seconds only provides data from the seconds in current minut, while im after something more like unix timestamp

[odd ember]

the most forward way is to have the function itself call out the name of the actor. delegates by nature cannot find callbacks easily

[dawn gazelle]

@trim matrix You can do it with the free low entry extended standard library plugin (free)
https://www.unrealengine.com/marketplace/en-US/product/low-entry-extended-standard-library

The trouble is, it generates it as a double, which is not natively available within Blueprints, so it's not intuitive as to how to do any math with it, but you can convert to strings and convert back to a timestamp.

[trim matrix]

i just noticed that my steamcore plugin has one called get server real time that works. but thanks. better go and look into that plugin too

[trim matrix]

I'm having an issue with a drivable vehicle.

When I activate it the Is Driving state stays True when I Activate again, which should close the Gate, so I can't quit the vehicle.

I'm not sure how the Tick acts here.

[trim matrix]

Once it Enters it looks like nothing before the Gate is considered.

[dawn gazelle]

I don't think Tick should be used like this. This is within your vehicle BP I take it?

and the "Box" variable you have there is a box collider attached to the vehicle?

[trim matrix]

Yep.

[dawn gazelle]

You should be able to use this event.

[trim matrix]

I'm already using an overlap node.

That does the work.

I think I got it working well with a Do Once one time.

[dawn gazelle]

The fact is, you're still using Tick to do some crazy logic which you probably shouldn't be doing as the checks you've put in place will fire for the vehicle on every single tick and you're also doing a cast, which isn't the greatest idea to do on tick either. You even have an "Is activating" check in there on the player character, so I'm guessing what you're trying to do is you have a vehicle that you want your player to "activate" so that you can drive it, yes?

[covert kestrel]

Any way for making the camera component of a spring arm cam do overlap collisions? I have a camera on a long spring arm (rotating around a building). I want the neighbouring buildings to disappear/reappear on overlap. This is set up on one building as a test, and it works with a different test pawn so that not working is ruled out. Also, if set to block all, the camera collides but will not overlap, as expected. There is no GetGenerateOverlapEvents for the camera. I have tried Root-SpringArm-StaticMesh(as collider)-Camera, but I still can't get it to work. Collision for the springArm itself is activated.

[hollow cape]

Can you just add a collision sphere to the camera?

[covert kestrel]

Lets try it.

[vivid aurora]

what does this even mean

[covert kestrel]

Cheers.

[vivid aurora]

it's 6am and i'm too tired for unreal to pull its bull where it decides that everything i want is bad and me just put up with it why would john unreal do this to us

[hollow cape]

try deleting and re-adding the bpi event

see if the parent needs to be recompiled

[dawn gazelle]

Or right click on it and select refresh nodes

[hollow cape]

forgot you can do that on events...

[vivid aurora]

i recompiled it

thank you darling

[covert kestrel]

how can I change the static mesh within instanced blueprints?

[hollow cape]

select the component, and set it in the details panel

[covert kestrel]

tried that, but the original updates too

[hollow cape]

what do you mean the original updates too?

ISMs can only be 1 mesh

Oh I just realised you aren't talking about ISMs are you

you need a public variable (exposed on spawn as well if you want to set the mesh var in a Spawn Actor From Class), and then you need logic (probably in the construction script) to set the static mesh components mesh to the var

[zinc portal]

make a construction script that changes it.
You could make an array of meshes to choose from and make an integer variable instance editable, then use the integer as the index of the array

Harvey said it better

[hollow cape]

As a general rule of thumb, I would do an isvalid on the mesh var get, and have a default mesh for the false branch, so there is always SOMETHING until you change it

[odd ember]

validated gets also exist

[hollow cape]

yep, but that involves extra explaining

[covert kestrel]

Although you are right, and I SHOULD do the construction script, your experience far outweighs mine and it will take me hours to figure it out having to search the books and youtube etc. It's only 6 or 7 buildings so I'll just make multiple blueprints and get on with it I reckon. Time is against me and I spend enough hours going round in circles.

[hollow cape]

do these buildings have some kind of custom functionality, or are they just static meshes

[covert kestrel]

just massing. Dont do anything, just disappear and reappear when camera passes through them.

let me quickly see if I can do an array

[vivid aurora]

sorry to bother again but i have a new problem

and for reference, this is the function for setting the damage number

(in the hud itself)

...and i have to compress the video showing the bug

alright see you in five minutes

i should really lower my obs settings

[zinc portal]

I'll make you a video in a few

[vivid aurora]

ok this is the problem

excuse the music playing in the background as i work

several problems actually

not even bothering with the screen full of error since i get em all the time

as you can see:

1. player 2 does not launch properly

2. no one apparently launches on their client

3. the damage does change, but the meter only goes up with the self-damage button

[maiden wadi]

Looks a lot like replication or RPC issues.

[vivid aurora]

also, the floating gold pans are just there cause i didn't attach weapons yet

and yea

how do i fix those issues?

[maiden wadi]

Hard to say. Which one do you want to start with? Cause those are different problems.

[hollow cape]

Also.... the screen full of errors shouldn't be ignored. When you see errors, trace them down and fix them.

[vivid aurora]

how about no one launching properly

[maiden wadi]

What triggers the launch?

[vivid aurora]

yeah i know i know but it's too much to do with these glaring issues

[vivid aurora]

this function in the pawn

[stiff hound]

Hello, does someone knows how to increase NetworkPlayerStart limits over 10 000 units ?

My character can't move over it

[vivid aurora]

and in the weapon bp

[hollow cape]

holy mother of spaghetti

[vivid aurora]

sorry

this is my first time with networking things in ue4

[maiden wadi]

Launch should be ran on server, not owning client.

[vivid aurora]

and also im new in general

i checked "dedicated server"

[hollow cape]

There's a TON of good stuff pinned to #multiplayer

I would suggest going through...all of it

[vivid aurora]

ohh

gee

alright

if you think they'll help, i won't doubt you

[maiden wadi]

eXi's compendium really helped me. Read it three times.

[vivid aurora]

OHHH you mean the LAUNCH as in LAUNCHING MECHANIC

ok ok sorry

ill go and fix that right away

[maiden wadi]

Yeah. Launch on server should also make it happen on client.

[hollow cape]

1000000000%

[vivid aurora]

if i set it to server it just does nothing now

[maiden wadi]

Also the RPC doc is a pretty good resource. Helps you understand really well how machines can communicate with the two RPC lists.

Where is it being called from?

[vivid aurora]

the pawn

[maiden wadi]

What event triggers the launch initially?

[vivid aurora]

what do you mean?

[maiden wadi]

Is it an input key, something that happens from damage, or?

[shut magnet]

hey guys anyone here have made resizable ui like in most mmos?
how do you make it so it can be resizable

please ping me btw

[hollow cape]

@shut magnet #umg is where you want to ask

[vivid aurora]

i put this in the weapon actor

[maiden wadi]

What calls this event then?

[shut magnet]

ok kharveyh

[vivid aurora]

and this is run when you left click

cause o this code in the actual character

[maiden wadi]

Okay. First off replicating to owning client is pointless here. Input is always done on the client. So you're already on the client. From an input event, the only networking you can ever do is a Server RPC to get to the server version of this actor, and that's assuming that your client owns that actor. Clients only own their controller and possessed pawn by default.

[vivid aurora]

where have i replicated to owning client?

oh.

so what do i do to make ANY input happen at all?

[maiden wadi]

From a client, the only thing you can do is Server RPC.

Is your gun actor replicated?

[vivid aurora]

fuck

is it?

im checkin

uhhhhhhhh

depends?

[spring hare]

Does anyone know how to stop TAB from cycling through widgets?

[vivid aurora]

oh im blind oopsy daisy

now it's replicated but the little guy still won't move no matter how much i hit him with this solid gold frying pan

also i discovered that the damage doesnt actually go up when i hit him

[maiden wadi]

Since it wasn't before, I'm assuming that you were spawning weapons client side as well. You should only spawn and attach the weapons on the server, where you can also set their owner variable to either that player's pawn or their controller. Then that weapon can send server RPCs.

Here, I have a simple multiplayer project set up at the moment so I can make a quick demo.

[vivid aurora]

oh ok

[zinc portal]

@covert kestrel here
https://youtu.be/yEUlrvJ_rSg
accidentally had the right side cropping the window so you miss some non essential stuff. You can always ask for a refund 🙂

[maiden wadi]

@vivid aurora Here. Start with this in the gun.

[zinc portal]

do you kn

@covert kestrel, do you know how to change a variable to an array?

beacuse that bit is cropped...

[covert kestrel]

Awesome thanks. I'll watch this shortly, just playing with the visibility timeline, it's a bit harsh the on and off for my liking, needs smoothing and also, maybe even not full visibility.

[maiden wadi]

@vivid aurora In the player's pawn, do this. This will allow you to shoot things and damage it on the client.

[zinc portal]

click there and change to rubix cube (3x3 grid)

[maiden wadi]

@vivid aurora I'm out for a bit. Try this out and see if it works for you. Can help in a couple of hours if you're still having trouble with it.

[covert kestrel]

no, well yes I think I do, but I couldn't find it on the drop down to change it. I add a variable, then go to details to set it to whichever class or reference etc

[untold rose]

Hi, I roughly know how child blueprint classes work, but I was looking for a way to split my player blueprint into multiple separate blueprints, both for organization and to help avoiding version control "stepping over eachother" situations.

How can I make it so I have a player blueprint, that itself has almost no code besides including the code that is written inside other blueprints?
For example, movement, a scanner ability, attacks/weapons... would be written as much as possible in each their own blueprints, and then all combined back into the player blueprint.

So if I'm tweaking the movement code, and my friend wants to finish the scanner, he can do that instead of having to wait for me to be done and push my changes.

Is this even the best approach with Blueprints? Maybe there is something else that fits these needs better

[violet wagon]

@untold rose you could use a blueprint interface or the "gameplay abilities" plugin. Both will let you make functions in other blueprints that you could use in your character, but not edit in your character. Im sure theres other ways but i cant think of them off the top of my head.

[untold rose]

Blueprint interface.. I'll look at that

[vivid aurora]

didnt work for me

had to tweak some things to work with my system tho so it may just be my fault

[violet wagon]

@untold rose im sorry not a BP interface, i meant function library/macro library. BP interfaces are still very useful if youre new to the engine.

[untold rose]

Ok thanks

[tepid pilot]

i would use components

depending on what implementations you guys are working ofc

[vivid aurora]

who are you talking to

[royal rain]

hey so idk if this is really simple but i thought i wanted to try and take the marble game to a new level, i want to make a marble racing game, where you control a ball, but i have a few questions/design choices i want to make with it

[covert kestrel]

got it, watching it now, sticking to set visibility boolean. I am wondering, can the box collision be changed/resized to suit? I guess not.

[royal rain]

first most obvious question is do i make it so i can drift with the ball, or if i should get the controls just right so i the player feels like they have control over a ball well enough to not have to drift

[zinc portal]

if the collision was made for the static mesh it would change automatically in the mesh swapping system

[royal rain]

and is it easy to get a ball to move with motion the way i want it to

like for a racing game

[vivid aurora]

now only the server gets the weapon, so it doesn't work anywhere on dedicated servers

[royal rain]

i guess you have the rolling template so i can just modify that

[vivid aurora]

also, characters launch, but don't go anywhere

[hollow cape]

Again, I'll reiterate that you would be better served going and reading at minimum the Networking Compendium pinned to #multiplayer

[vivid aurora]

sorry

[hollow cape]

No need to be sorry. The reason I'm saying that is people can help you solve one little problem at a time, but it will take forever and you won't learn how it works....so you won't know how to debug at all

[royal rain]

i feel like the ball starter is almost there but it needs some more control maybe i dont need a drift but let me see if i can just give my self more control on the ball, though i dont know how

[latent arch]

hey guys so i have a question about camera movement, i have a nice springarm setup and some delay. The camera inherits all the arms movements for a nice "imersive feel". But id now like to level the camera on the end of the spring arm. So i want the arm to inherit the actors movements but the camera to stabilise on the spring arm. im getting confused with relative rotations ehehe

mostly i jsut want the camera to stay horizontal unless there is a mouse input

[upper adder]

Is there any way to get/set a "sound time" type variable? I would like to see at what playtime a sound component is and adjust the time.

[dawn gazelle]

You're asking a design oriented question which we can't really help you with. You would have to try it out yourself and figure out if the ball drifting is the feel you want for your game, and then have others possibly test it to see how they like how it feels, and then go from there.

[odd ember]

you can get time from any sound

[upper adder]

how?

[odd ember]

... by pulling out the context string and typing in time? there should at least be get duration and get current time

[upper adder]

can't find anything like current time :/

there is a duration but that doesn't really help me

[final hound]

I want to possess another character, but only if its visible to my pawn. Should this logic be in my gamemode, charController or on the Char?

[dawn gazelle]

This might work for you

Just need to reset the timer whenever you play something new.

Or pause it if you pause the playback of the sound.

[dawn gazelle]

Probably on the controller, but should also work on char.

[upper adder]

Yeah that would be the backup solution, but is there really no cleaner way?

I mean i'd always have to kill the sound

and then respawn it at the time i want

[odd ember]

sorry it's actually through an OnPlaybackPercentage event node

[odd ember]

also it is strongly encouraged to use create timer by event and use the CreateEvent node instead of using the timer by name variant

[odd ember]

also, check this: https://answers.unrealengine.com/questions/578841/how-to-get-current-playback-timeposition-of-the-so.html

[upper adder]

thanks

[dawn gazelle]

Yeah that's a much better solution 😄

[marble nova]

Hey, im starting out and im trying to make a day night cycle so i set this up from a tutorial... from what i understand every 'tick' it should be rotating my sun light by adding a value to the Y rotation... this seems to be working, i wanted to change something for night time so i tried getting the rotation... however when i actually look at my lights rotation it keeps going back and forth between negative and positive vales, and then switching the z or x axis... any help with whats going on here?

Y rotation should read more like 0, 124, 0 & counting up.. instead of -179,56,-179 and counting down

[little cosmos]

Hi! I'm looking for a way to save the position in the level where I enter a building (switch level) so I can come back to the same location again when I switch back out of the building. How can I do that?

[dawn gazelle]

Single player or multiplayer game?

[little cosmos]

Single

[dawn gazelle]

You can store the location in game instance. I'd possibly recommend creating a map of strings to vectors with the level name set in the string and the vector the location of the player. Whenever a level loads up that requires to know the old position, have it look in the game instance to see if it can find the value in the map, if it does, load it, and then clear it from the map.

[little cosmos]

I'll look into that. Thanks for the direction!

[odd ember]

#graphics

[trim matrix]

Oh yeah, sorry.

[shadow saddle]

if i want to do something like diablo game where u press left click and ur chara move towards where u click

can u achive this using Get Hit Result under Cursor

and break the result

[maiden wadi]

You can. You should check out the TopDown template.

[timber cloak]

https://imgur.com/a/KxTywKy

by right, this should be giving my player's the fruits from array of fruits, right?

just to clarify

[odd ember]

it's going to give your new character a fruit string

[timber cloak]

but apparently it does not

[odd ember]

whatever that may be

[timber cloak]

This is in GameMode

[odd ember]

your string array may be empty

[timber cloak]

not empty

have 10 fruits

[odd ember]

have you debugged?

[timber cloak]

hold on

[weak kindle]

L have create a widget Iphone and when my character click a icon it will run a media but media doesnt output sound cause its image how can add the sound??

[timber cloak]

https://imgur.com/a/JxZ0sM8

[odd ember]

you should debug

[timber cloak]

yes breakpoint

[odd ember]

to see if your values actually stick

[timber cloak]

it goes through

let me print string right after the spawn

[odd ember]

yeah printstring every string

[timber cloak]

it shows

but then my player isn't getting any

https://imgur.com/a/FC95PMJ

this method, worked on Enum

however, the string's looping practice isn't working

let me restart the whole engine project

[odd ember]

no

you're not testing it properly

you should test the array you constructed

not some random new array

[timber cloak]

well, if player gets a fruit, it will be printed out with that Page Up input

which worked for Enum practice

if client 1 gets "painter" as enum, it prints "painter only

similarly if client 2 gets "dentist" enum, printed dentist only

there's no random new array

it's fruit variable in thirdpersoncharacter class

there's only 1 array
