blueprint

[lofty rapids]

it won't fix your problem but it makes the booleans useless you need a branch if you want to use the boolean

[mystic zodiac]

So... I always heard there's no way to make a horizontal character capsule or use a custom shape without rewriting the character class, BUT this clip shows someone extending the collision of their capsule component just with this random trick. Why does this work? Is this intended behavior? https://www.youtube.com/watch?v=H3U6D8XAFRE

[trim matrix]

so, how do i make it work..

[lofty rapids]

so now it's spawning back, but the system isn't showing at all ?

the first time, or the second time it runs it's not showing

in your collision turning on and off

[trim matrix]

it runs when i collect the first coin then not again

so get rid of the event?

[lofty rapids]

well you want the event to spawn them

after you make them disappear

but if you just shut off the box collision

and turn it back on

it should just be the same code running and be fine

[trim matrix]

im confused what difference does that make if its the same code?

[lofty rapids]

it's different code for the collision enabled

i'm saying your not changing any of the other code so it should spawn

but by turning off the box collision, that event won't fire untill you turn it back on

so you can't get the coin while its invisible

[trim matrix]

i cant get it while its invisible w how it is rn

[lofty rapids]

interesting, well everything works but the system ?

idk much about niagara maybe #niagara might know this specific thing
or someone else can see the problem because it looks legit and you didn't change any of that code

[lusty mulch]

anyone know how to convert transform data between houdini and unreal engine? I tried to export out a csv from houdini for my points that has the full transform data of the points. I then read this as a data table in blueprint and try to use the data to spawn static meshes with the correct location, rotation, and scale to match houdini. Really struggling on the rotations though.

[lofty rapids]

whats the struggle ? if you store the data you shoul be able to retrieve it

[trim matrix]

yea, everything is working other than the system im not that annoyed ab it not showing rn, im still getting things just made for the game in general

how do I get back to a minal blueprint view rather then a full blueprint editor view

[lusty mulch]

well the rotation isn't matching, I can get it very close but still off. fairly confident location/scale is right. I assume the struggle is the difference in coordinate space between the two programs.

[trim matrix]

currently following a tutorial where they have this

however I have this

and as such theres values they have but I don't it seems so struggling to get thing working

[lofty rapids]

did you make the same kind of class ?

or did you click open full blueprint editor ?

[trim matrix]

clicked the open full BP editor

i've found anyway the right way to do what I need

so it's all good

[hexed inlet]

UE4.27
So in C++ I can make blue BP functions and green BP functions, to keep explanations simple.

Can I make "green" BP functions in the BP Editor? Ie., I want to avoid the execution line.

[lusty mulch]

make it pure

[hexed inlet]

Ohhhhhhhh

lol

It's a checkbox

[lusty mulch]

yes when you have the function selected the details should have a "pure" bool

[hexed inlet]

Thank you. I didn't even think to look at the options 😄

Me: Sweet, I can move a million pieces of grass with individual transforms via shader, updated via texture data, using HISMs, on the render thread.

Also me: How do I make a green function plz?

[trim matrix]

im trying to make a block that falls after a few sec, but is activated by the player, like doughnut blocks in mario 3dworld. but when the player colides with the block nothing happens

[lofty rapids]

i use two timers

one fires off when collision

and the other fire offs after the time has passed to start dropping it

[hexed inlet]

What's stopping it from falling in the first place?

[trim matrix]

nothing theyr meant to just be floating platforms that fall once the player walks on them, but with a little delay to give them time to move before it falls

[celest oar]

in a recursive function, if i do a break, will it jump to the previous called function or is it gonna hit my "complete" pin?

[hexed inlet]

Nah I mean, before the player walks on it, why isn't the block already falling? What's keeping it in place?

[trim matrix]

nothing..

[dawn gazelle]

Just a heads up, pure nodes should only be used for returning values and never for modifying any state. Your "Update 3Motion Vectors" for example would not be a candidate to convert to a pure function as it doesn't appear to return something and by the name of it sounds like you're changing the state of something.

[hexed inlet]

So what are you changing to tell it to fall? It might be obvious but I'm not sure.

[trim matrix]

begin overlap, with the player

[dawn gazelle]

Are you sure tick is enabled?

[hexed inlet]

Sorry, I mean, what's actually saying "Ok move downwards"

[trim matrix]

i sent screenshots of all is in the blueprint

[lofty rapids]

also what is resetdelay set to ?

[hexed inlet]

Ah yeah fair, I think the low res threw me heh

[dawn gazelle]

The other thing I can see is maybe "Fall Speed" doesn't have a value or is extremely small?

[hexed inlet]

Yeah that was just the first one I grabbed a screenshot of. Ty for the tip though.
This is what I'm making pure:

[lofty rapids]

fall speed * delta will make it small it would have to be pretty big actually

maybe it's moving but you can't see it it's so small

[hexed inlet]

I'm aware of that issue where Pure BP functions get fired off for every output line, while non-pure don't.

[lofty rapids]

bp first i heard of pure function, still gets me mixed sometimes i forget i'm just not used to them

[hexed inlet]

It gets messier in C++. I believe it turns const BP functions (that you wrote in C++) into Pure without you asking, and you have to explicitly say "No... I want non-pure thanks". And it's this way because by the time they realised it would be good to support const non-pure functions, it would have broken too much behaviour to stop const functions becoming pure by default.

[lofty rapids]

what is a const function ?

[hexed inlet]

Heheh. Just a function in C++ that you demand must not change anything.

Sometimes you want a function const, sometimes you don't, but if you're writing BP functions in C++, that const difference irritatingly flips the function between Pure and non-Pure.

[lofty rapids]

makes sense, i'm new to c++ i done a lot of c but never heard of const there

[spark steppe]

you can use BlueprintPure=False to turn it into a "normal" function

[lofty rapids]

i use a blueprint function library and to change to pure i think its a uproperty setting

[hexed inlet]

Yeah. So if you put a const on the function it makes it Pure also, even if you didn't use that setting.

[lofty rapids]

interesting it kind of make sense, thats probably how they implemented pure function ?

[hexed inlet]

Yeah there's logic in the thinking

[full flax]

I have a tombstone blueprint with a simple tombstone static mesh that I want to add numbers to...up to three digits. I have the digits as decal material instances and three decal actors in my blueprint...My initial plan was to have an int variable with the number to appear on the stone and then do some math to determine what digits to show on each decal actor....is this sound? or should I go a different way?

[hexed inlet]

But it still annoys me heh... since Pure functions need a bit of extra concern for performance.

[lofty rapids]

they are real usefull for one offs of data

[wraith loom]

How do I find the "On component begin overlap" node?

[lofty rapids]

click on your component in the components at the top left, then scroll down in details to the bottom

[full flax]

I thought about this method but isn't string manipulation slow?

[lofty rapids]

maybe maths is faster idk

i just figure it's built in and i don't know how slow your talking

it's not noticeable to do that on a small number

[full flax]

well I could have a LOT of these on screen at a time, so I want to be super efficient if I can.

it's an insane asylum cemetery

[lofty rapids]

i c

i would make it a function in c either way

it's your best bet if you need to make a lot of calculations

if it's always a year then the maths shouldn't be too bad

[full flax]

oooh I've not done C yet....I really need to....I'm scared of figuring out how to add C to UE in linux because that's what I'm on...I know C/C++ but I've not toyed with it in UE

nah, it's not years it's grave numbers...asylum graves just had sequential numbers on them

[lofty rapids]

i c

[full flax]

simple numbered paupers graves

[lofty rapids]

is there a max, are you doing a bunch on the screen at once ?

so like you kill a bunch and there graves show up right ?

[full flax]

no just a prepopulated grave site and there will probably be some kind of puzzle using the numbers...it's a mystery/puzzle game

[lofty rapids]

oh i c, so you load these on begin play or something ?

[full flax]

yeah I was putting this in a construction script

[lofty rapids]

how many of them ?

wdym a lot

[full flax]

I'm hoping to do 100+ at least

[lofty rapids]

i would probably pass it the number, and run it on begin play

so it's not trying to do in one tick like a loop or something

oh your using construction script nvm
so they are pre built in the level already ? performance doesn't really matter then

[rare vault]

I'm trying to modify data table in-editor and add row node still isn't working unless you use c++ I guess. Would it be possible to feed modified array data of this method back into the data table in the end?

[burnt edge]

Does anyone have experience with combining different layers of post process settings additively on a single camera? Seems to be quite a bit of work and wanted to know if anyone has done this or can point to some resources about it.

[hexed inlet]

I do not love refactoring Blueprints. Even just removing 7 occurrences of a variable across it... I get scared I'll mess up and have a hard time knowing where

[lofty rapids]

set it a lot higher

3.0 * whatever delta is is really small

[trim matrix]

the fall speed is set at 200

[hollow cove]

why would you combine different post processing layers rather than alter the post process at run time

or just set the single post process

[lofty rapids]

i would also just move the actor in the world instead of adding offset to it

[trim matrix]

wdym?

[lofty rapids]

your using add actor world offset, when you could get the current location, and add to that, then set it

i'm guessing the offset will stay even when you reset location

[lofty rapids]

this really is small set it a LOT higher

[burnt edge]

That's what we're trying to do. Alter the post process on a single camera at runtime.

[trim matrix]

what node is current location, that dosnt show for me even with context sensitive unchecked

[hollow cove]

?

[lofty rapids]

there is "get actor location" and "set actor location"

get actor location, split the struct, subtract from z, set location

but first thing i would do put a print string on the true of the branch

it will really hurt performance on tick, but just to make sure it's triggering

[trim matrix]

its not printing

[burnt edge]

Yup. So now imagine there are a couple different status effects in a game, each associated with it's own post process settings and materials. How do you go about blending them together, and not just overriding one another.

The materials are pretty easy, cause they're in a stack and each layer has a weight.

[lofty rapids]

on the begin overlap event, check if the cast succeeds and it's running

[trim matrix]

i put a print on cast failed and it didnt print so i assume its working

[lofty rapids]

put a print in start falling

make sure it's running

[trim matrix]

nothing printed

[hollow cove]

Other people probably know this better than me, i'd ask in #materials. My niave approach would be to just combine the materials into one material with parameters to have more control and alter the material instance on runtime

[lofty rapids]

put a print on success see if something prints

[trim matrix]

nope nothing printed

[lofty rapids]

so the collision isn't happening

[trim matrix]

how do i fix that

[lofty rapids]

for one thing i would create a seperate box collision

and use that

[trim matrix]

i had that at first but then i figured the model wouldve been easier on its own

[lofty rapids]

it's easier with the box

put a box collision in

and try that event with a print see if it fires

[robust mural]

how to connect object reference to static mesh

[trim matrix]

that made it print

[lofty rapids]

so use that, your mesh probably doesn't have collision but it's probably more performant to just use the box

[trim matrix]

and my player mesh fell through propperly but the block mesh itself didnt move

[lofty rapids]

you put a print string on the tick and nothing prints ?

try off true and false

see if anything prints

or just off the tick itself

[trim matrix]

it prints off the tick itself

[lofty rapids]

but not on true for the bool ?

[trim matrix]

nope

[lofty rapids]

is bisfalling in this function start falling local ?

are you setting a local variable, or the public one ?

[lofty rapids]

the one here has a capital B

looks like a local variable to the function

[trim matrix]

do i need a cast then?

[hexed inlet]

If it was a local it'd be under "Local Variables"

[trim matrix]

bc the other variable dosnt show

[trim matrix]

thats the only bisfalling

[lofty rapids]

is the function in the same blueprint ?

[trim matrix]

yea

[lofty rapids]

then know, just remove the set with the capital

and drag in the one with the lowercase b

make sure you use that on your functions

[trim matrix]

it capitalized it

[lofty rapids]

for some reason you have another variable

[trim matrix]

theyr the same

i dont

i dragged it out and it capitalized it

[lofty rapids]

hmm, maybe thats an unreal thing

makes sense bBool

[hexed inlet]

Yeah it's just Unreal trying to be smart, capitalising in the graph but not in the name.

[trim matrix]

give it another name then?

[lofty rapids]

just make sure you use that variable in each set and get

[trim matrix]

i do

[lofty rapids]

and that your not using local variables

hmm

thats really odd, that your setting the variable but it's not registering as true on tick

idk why that is if your using the same variable and tick is firing

[robust mural]

how to connect object reference to static mesh ?

[trim matrix]

the actual collision respawning is working just not the mesh moving

should i just rename the variable?

[lofty rapids]

i mean it wouldn't hurt rename it see if it changes all of them

but it doesn't print on true ? thats what is confusing me

if that doesn't work then something is f'd

[trim matrix]

that made it print once the block falls

but the mesh still dosnt move

[lofty rapids]

ok it's printing

did you change it to get location, set location ?

on tick when it's going down ?

instead of offset

[trim matrix]

i started to,

[hexed inlet]

Er... aren't you setting the hit block to Ignore, but then telling the hitter, not the hittee, to move?

[trim matrix]

what?

[hexed inlet]

Like, that graph you just posted now isn't the block's graph, is it?

[trim matrix]

it is why

[hexed inlet]

Oh, my bad, thought it wasn't

[lofty rapids]

ok so all your doing now is printing

so now you just got to make it drop

get rid of the print ontick print sucks

[trim matrix]

is your movement speed my fall speed variable?

[lofty rapids]

ya your result after multiplying with delta

but you want a fairly high number

because delta is small

thats why i was saying 3.0 is real small, * delta it's tiny

[trim matrix]

so go from the multiply node into the subtract node?

[lofty rapids]

i think so

whatever you want it to move by

your subtracting a number from z

and setting it

so whatever speed you want i would mess with it a bit

[trim matrix]

my fall speed is 200

[lofty rapids]

give a try, it just takes some tweaking of the numbers to get right to your game

[trim matrix]

can i keep the block collision so the player could ride the block to their death if its over a pit, but have it despawn and respawn at its original location still?

bc its falling at an ok speed, but the player falls quicker bc the collision

[lofty rapids]

you don't have to shut off collision

thats all up to you

[trim matrix]

oh

[lofty rapids]

but the way you have it you may find some weird stuff if you jump and land back on it

because of the way your doing your collision

[trim matrix]

am i able to make it so only touching it from the top makes it fall, maybe add a 2nd box collision that isnt a trigger on the bottom so u can only make it fall from the top?

[lofty rapids]

i mean you can just change the shape and put the box at the top

does the mesh have collision ?

[trim matrix]

yea just box collision

[lofty rapids]

so you can go through the mesh ?

because think about it, if you can't go through the mesh and you put the collision just at the top

you should be all set

because it won't go through the bottom and hit it

you may want to make the sides a little in so you can't bump the top side also

[trim matrix]

yea the player keeps falling through the mesh

[lofty rapids]

so just don't turn off collision in the code

you know what the nodes are doing ?, read there names they are fairly descriptive

[past token]

Any tips on how to make blueprint faster than it is?

[trim matrix]

what do i set it as so the collision isnt disabled

oh i got it

now im gna test n see if thers any other bugs

[lofty rapids]

jump up while it's falling

and land back on it if you can

might f it up a bit

because the collision will make it run again, you'll nee that boolean that was mentioned earlier but it may still work just the code is weird

[fiery swallow]

1. Rewrite the code in a more performant way.

2. Rewrite the code as a function in c++ and then call it in blueprints

😐

Not very helpful I know but those are your options

[lofty rapids]

watch out for loops and pure nodes

thats a performance hit

[past token]

alright will look into that, im still very new to blueprint though. But thanks for the advice.

[fiery swallow]

There's almost always a more performant way to code something in blueprints. I've gone through like 5 iterations of code yesterday to make a scoring system cost less

You just have to be creative, knowing what costs more helps

[trim matrix]

it works fine other than when the block respawns it warps the player to the block respawn instead of on the ground

[past token]

and that is loops and heavy calculations?

stuff like that

[lofty rapids]

you could briefly turn collision off, move it back, then turn it back on might go through the player i'm guessing for some reason it's colliding

[fiery swallow]

As someone point out loops and pure nodes can kill, array nodes that go past 500 seem to slow down performance, heavy calculations is a big one. Using math expressions will reduce that cost significantly

[trim matrix]

how would i do that?

[fiery swallow]

Re use actors, spawning is an extremely costly process

Overlap and collision checks will cook your project

[lofty rapids]

funny thing i spawn a bunch of stuff on the fly

it works great

as long as you keep at a decent number of stuff it works

[past token]

But dont i need to do that all the time, i plan on having bows and sword in my multiplayer game?

[fiery swallow]

Spawning actors is usually not a problem unless you're spawning them by the thousands. Since we don't know what game he's making we can't rule any optimizations ojt

[fiery swallow]

Sometimes it can't be helped, and in those cases it's totally fine

[past token]

I plan on once im good on making a survival multiplayer game, lol.

[hexed inlet]

😄

[fiery swallow]

You just need to make sure things that don't need collision overlap checks, aren't checking for that sort of stuff

[past token]

ah okay

and what exactly is meant by "pure nodes"

[lofty rapids]

with the set collision node, when you put the thing back, right before shut off collision, then right after turn it back on, i'm not sure if it will work but it's worth a shot

[fiery swallow]

Make sure your actors have "tick enabled" checked off if you dont plan to use the tick node on them. Just because you aren't using the tick event doesn't mean they aren't ticking it in c++, when you have thousands of actors and particles ticking it does cost a few extra ms 😉

[fiery swallow]

A function that you selected as "pure" there's no longer any execution pins

Blueprints handles that by reading every single pure function in your code that connected to something else, even if it doesn't end up getting used

If you use a select node and connect 10 pure functions to it, even though you're only gonna select one, all 10 still got their code ran for no reason

[lofty rapids]

pures are green

[past token]

ah okay, thanks.

[fiery swallow]

I can go on all day about unreal engine optimizations... if you can be more specific I can probably give a more helpful answer haha

[hexed inlet]

In this image, the GetPlanetUpNormalised function gets run twice.
But the GetInputHorizontalAcceleration function only gets run once.

The green one is Pure, the others aren't.

[past token]

you dont have to spend all your time helping me, lol. Hopefully i will learn it on my journey. But thanks for the many advice i reaplly apreciate it. 😄

[past token]

Im not experienced with this, but is what your trying to say, i shouldt have the green part of the script, and only the blue below?

[hexed inlet]

They're both fine. The greens ones don't need you to run an execution line through them, so when it's something simple like "GetSomeValue" they're good.

The thing to avoid that the image shows is pulling 2 lines out of 1 output with the green ones.

With the blue functions, that doesn't cost extra. With the greens, it does cost an extra run for each line. Plus it's easy to forget that the green ones are indeed getting fired an extra time for every line coming out of the one output.

[celest oar]

im doing a recursive function and return doesnt seem to break out of it? am i missing something here?

[robust mural]

How can I connect a static mesh reference to a object reference ?

[past token]

okay, so for best peformance i should use the green one, but only one yellow line should be used?

[hexed inlet]

Well, you use the blues and greens for different reasons, but yes, typically only drag one line out of each output pin with the greens.

[lofty rapids]

pure functions are very useful

but you just want to watch how many times it runs to get a simple value you can cache

everything plugged into it runs

[lofty rapids]

show the code

[celest oar]

hopefully it is visible enough

[past token]

okay thank you for the explanation 🙂

[celest oar]

it is doing the proper steps, at least as far as i checked, but it always goes ot that last return on the complete pin

i am sure there are gaps in my knowledge in this area

[dark skiff]

For a game jam game,
Anyone know what method I’d use to be able to play a 2d game on a screen in my FPS game?

(Not that it’d load you into a new 2d level, but that you’d still be able to look around in the FPS while the 2d game is on the screen)

Would I try’n run 2 levels at once, and render target the 2d game onto the screen texture? Or would that even work?

I’m not sure how best to describe it, somewhat of a beginner still, so I don’t know what I’d look up

[robust mural]

@lofty rapids is it possible to get a static mesh reference from a object reference ?

[hexed inlet]

Quick dirty example of the above re: pure vs non-pure

[robust mural]

@dark skiff did you think about widget blueprints ?

its like a user interface that can pop out in the screen

the widget could maybe stream it

[dark skiff]

I’ve really only messed missed with widgets for UI,

The “2d-game” would need to be displayed on a 3d object that is modeled to look like a “screen”, as opposed to the actual screen (sort of like the pic i attached)

[robust mural]

then you need a blueprint actor with a plane, and the plane you need to assign a texture

there is something called canvas render target

its rendering a texture from a blueprint

[dark skiff]

Right, I think using a render target would take care of the texture, I’m more so just wondering if I need to make the 2d-game a separate level or something, and if I could even render-target a separate level to a texture (can u run 2 levels at once? Can I do the same thing with 1 level?)

That sorta thing

[robust mural]

need to be streaming the second level somewhere far from the current level

[hexed inlet]

You heard of an indie game called screenbound?

[robust mural]

and the blueprint will be a camera with render target, to render the texture

because if not streaming the level, that means its not on thread

[dark skiff]

Just looked it up, looks sick btw,

But YES that’s what I’m thinking of (minus linking the gps movement to 2d movement, I just wanna be able to play the game at all while in fps)

[dark skiff]

Ok ok, looks like I’ll have to look into level-streaming then?

[robust mural]

then you need some interaction with the user, when he clicks some button you change the player controller

and inherit the pawn from the different level

kinda needs deeper look because if you inherit different pawn you might get teleported to the different level, and thats not what you want

[robust mural]

yes

maybe you can use the same player controller, but with a function to control different pawn as well

[dark skiff]

Cool cool, for sure
Thank you 🙏

May ask general chat for their take as well, ‘n see if they got any experience with that😎

[robust mural]

is it possible to get a static mesh reference from a object reference ?

[lofty rapids]

so thats an array of objects ?

[mental trellis]

Cast it.

If the cast fails, it's not a static mesh.

[tepid willow]

I'm trying to spawn an actor within an UObject but the node is not appearing in the context menu. Does anyone know a workaround for that?

[mental trellis]

Are you trying to add the uboject in the construction script?

[tepid willow]

No, I have a normal UObject BP, I have a regular function that I want to spawn an actor in

[mental trellis]

Oh. It's a UObject BP?

[tepid willow]

Yes

[mental trellis]

You may need to override GetWorld or it won't let you use world-context-related objects, like spawn actor.

[tepid willow]

Yeah, makes sense, thank you

[mental trellis]

You may simply need to override it and do "Get Outer -> Get World"

Depends on your setup, of course.

[tepid willow]

Yeah, I just realised that I don't even need UObject BP.

I actually was thinking on how I can create an easy way of determining where pickups for a quest should spawn. I thought about creating a UObject BP with a function SpawnItems that takes the quest, the NPC, and the player as arguments, and spawns items using that information. The object would be then assigned to the relative quest objective to act as a "callback" to actually do the logic.

Do you have any idea how I could achieve that in a good way?

[mental trellis]

Use an actor?

[tepid willow]

Yeah, it's a solution, I think I will go with that unless something else comes to mind

[lunar musk]

I'm implementing a simple drag and drop. My problems is when i reopen inventory, items are not in the last position

[mental trellis]

I'd fix that before you try drag + drop then.

[lunar musk]

Shure

I need to save index i think

[woven pond]

Hi not sure if what im searching for is named what i think it is but if i create a primary data asset PDA_Object is there a way from blueprints toget an array all DataAssets that use this PDA_Object as it's parent?

Or if theres is an altrernative for getting an array of children from a specific primary data asset

[lunar sleet]

You can make an array of DAs with object type PDA

[silk bay]

Eek! I packaged my game and it broke the behavior trees. Enemy AI works fine in PIE but they just stand around playing the .exe. How could I troubleshoot something like that?

[idle vigil]

in my multiplayer card game, i have ability cards and I encode them using integer values. Like value 0 represents the ability card that gives the player body armor etc. I want to create an actor that is global where every component can ask it information regarding the ability cards. For example when I spawn the ability card on the table, the card actor can ask that global actor which image should it have on the card if its integer value is '2' etc.

What is the best or industry standard way to do this?

So far i thought of adding a component to the game state as this information holder since every actor can call get game state but not sure if thats the best way

[ember lichen]

So I get the "has to have Simulate Physics enabled if you'd like to addForce" error, which is correct because I disable Simulate Physics during my initial cutscene in order to make the player not move. Can I check if simulate physics is enabled and if it is, then apply force so it doesn't error out?

[frosty heron]

representing them with number sounds unthinkable

use Uobject instead imo

[past token]

Im following a tutorial, and i was wondering if how he set it up was the best solution. Beacause wouldt you save performance, if you instead of one green function that gives input to two other nodes just had two seperate green fuctions for both two nodes. Beacause if i run the green fuction wont it be ran twice? even though i dont need to send info to the endoverlap part when im beginoverlapping? (dont know if i was clear or not)

Instead shouldt it be like this:

[frosty heron]

this is the same thing as above

just a matter of readibility

Pure function will get executed either way, when the node it connects to get executed.

[past token]

yes but the first one has two lines from one, so it will execture both enable input and disable input, even though i for example just began overlapping?

wouldt it be better keep them seperate beacause then green fuction wont be called twice?

[frosty heron]

no

it will not execute both

this is what happend when overlap

and on endoverlap

[past token]

Okay, thanks for clearing that up 🙂

Hey guys I was wondering when playing in editor gpu usage 30% but when playing packaged game gpu usage is 100%

[lunar sleet]

Good, means it’s using all available resources 🙃

[lunar sleet]

You can attach insights to a packaged game and do some #profiling to find out why

You can even run certain console commands like stat unit and probably profilegpu as well (I didn’t try the latter)

On begin play of game mode for instance

[jovial dirge]

Anything out of the ordinary you are noticing?

Also this is on a RTX 4090, game uses 80%+ GPU and it's a lowpoly game

so any other gpu is getting 100% usage

[lunar sleet]

Not off the bat, but #profiling might be better at this. Also maybe restart your pc for sanity check

[jovial dirge]

For sure, thank you

Im following a tutorial, and here he uses a timeline to smooth the door rotation as it opens and closes? (The timeline has a curve to make it smooth).
But i was wondering wouldt it be very peformance heavy if i had a bunch of doors with this timeline, like if i had survival multiplayer game like Rust, would it be better to lerp the value, or are there other solutions. I heard you could bake the cuved animation, but idk how to do that.

[fiery swallow]

not really a problem unless you have a ton of doors opening and closing all the time lol

[warped juniper]

Hey, doing a system for stamina to be weaker as it runs out. I just wanted to have something based in ranges. (if above 40%, full power, if above 25% halved power, and below minimum power)
Thing is I feel the current way I'm doing it is way too convoluted

I just used some In Range nodes to check for the value to calculate tiers of power, and perform related actions accordingly

Though I guess it's still better than a couple branch nodes, I bet there's some better trick

[frosty heron]

@past token blueprint is slow to begin with. If optimisation is such a concern, you will use cpp to do the heavy task

It really isn't helping trying to optimise in bp

Multiplayer on top of that

[past token]

https://tenor.com/view/hell-nah-hell-naw-oh-hell-naww-dog-gif-9009732769714372825

[lunar sleet]

You won’t make a Rust kind of game in bp only

But also @frosty heron timelines in cpp? 😃

[frosty heron]

I don't know 🤷‍♂️

I would probably use bp if I need a curve assets

Imo optimising in bp is futile

[lunar sleet]

I mean it depends on what the issue is, if you’re calling get all actors Actor on tick, you can optimize that in bp by trashing that code 😀

[past token]

So if i ever want to consider making a big multiplayer survival game, it should most defintly be in c++?

[frosty heron]

For sure, I doubt you can do network seriliazation in bp

[storm shale]

you can

[frosty heron]

Have you got any samples I can look at?

[frosty heron]

Aim for smaller scope, even a basic mp game will require years of experience and blueprint multiplayer is very limited.

You certainly can't make a competitive shooter with bp, let alone mmo

[past token]

Its just very confusing to people like me who are new what the capabilities of BP and Multiplayer are when there are youtubes selling courses where they "make an online survival game".
https://smartpoly.teachable.com/p/ue5-multiplayer-steam-survival-game-course-remastered

[frosty heron]

I was in that course btw

Garbage as f

[past token]

in it?

[frosty heron]

Literary trying to use interface to replace casting

[storm shale]

Those courses... I don't wanna say anything bad but like. Usually tutorials that give step to step aren't very good. They only make something that -works- but that works really bad

[frosty heron]

For multiplayer game, Stephen tutorial is good for networking concepts

Imo

[past token]

who is stephen? I was actually following a multiplayer c++ course by Tom Looman. And a c++ beginner course by Dev Enabled.

[frosty heron]

I heard good words from Tom Looman, imma actually gonna get that before trying to escape tutorial hell

he is industry vet working in many game companies

but it cost like $300 or something

[past token]

his course also seems very imformative atleast the part i have done.

[past token]

yea, but i think theres in one of his blogs there is a link to get like 20 precent off i think.

i atleast got that

Hi everyone, I have a question that's stumped me hard. Add to the fact I'm primarily an artist and you see why I'm having trouble. I making a small radio station to play mid program and want the song information to display like this. I have my own music code working and it's consistent, so all I'm missing is this. Can I get some help please?!!

Like to just come up on the screen for 5 seconds then go away

[frosty heron]

Is this unreal related?

[abstract delta]

Yep all in bp

[frosty heron]

So widget?

[abstract delta]

I have made one and a mini ui that at least has the spots where I want the information displayed. I also understand casting to the playlist I made will be necessary. It's just after it idk

[frosty heron]

Just play animation that drives the text opacity?

Create widget animation in your widget blueprint

Call it fade in

Then when you want to fade in, you play the anim

[abstract delta]

I get that too (i made a splash screen for the program already!) My main question is how to get it to see what song I'm playing and display the information about the song in the spaces designated on the ui (maybe attaching text being casted from the playlist into a text box?)

I made an array assigned to each file that has the information plugged into it through variables

But it will run on all at once if I just connect them

[frosty heron]

You just get the element in the array that you want to play

Then pass that info to the widget, where the widget will update text, play animation,etc based on the data you send

[abstract delta]

Got you

So sounds like I need to fix the issue of the songs all playing at once while retaining their info

And that I'm on a right path

If I post how I have my code setup could you maybe help? Again my radio code works, just not the string of code with the songs and their info

[frosty heron]

Sure, it's not like you want to play all the song at once

[frosty heron]

Post it for the rest to see. Someone may able to help

I can lend an eye but if it's something that may take a while, we'll I got my own problem 😅

[abstract delta]

I understand I just really appreciate you responding

Plus I'm running off 25+ hours of sleep idk how much longer I'll stand

[frosty heron]

🛌

[dusky cobalt]

Guys, please help 😄 I need some idea how to better handle it. I have different actors in my game and I think I need better setup. Currently I have component on each actor which has ENUM and there I select if something is something. Does anyone see any way I could improve it? I tried to use tags, because they seem easier, but there is no way to switch on tags? Would I even use switch for that? I can provide more screenshots if needed.

[abstract delta]

1st pic is the code that works
2nd pic is the songs with the info in arrays attached to a custom function

[frosty heron]

a close up of this

[frosty heron]

Gameplay Tags, I think you can do switch on it? not sure don't have editor on me atm

[abstract delta]

each one is this just different song info

[dusky cobalt]

Hmm, that maybe could be cleaner. I will check.

[frosty heron]

This doesn't do anything?

[abstract delta]

That's the code that just runs on

[frosty heron]

this code is saying, make an array, set the array index 0 to null

so index 0 will be null

and you are not storing the result in a variable or anything

You should make a struct that defines your music

create an array of the struct and add to the array for each song

#blueprint message
Im looking at this and it has nothing to do with MusicPlaylist or TempPlaylist

[abstract delta]

Then what am I using in the pics of they aren't variable?

[abstract delta]

So array with the info, then plug that into the song file and do that?

[frosty heron]

You are making a tempory array out of 3 texts and you changed the temporary array value in index 0

this practically doesn't do anything

[abstract delta]

Correct, temp playlist is what I'm currently running the music playlist through to put music in from the editor viewport and test the code and sound at the moment

[frosty heron]

Make a blueprint struct , call it FMusicInfo

There, declare all the info you need.

1. Title
2. Comment
3. Audio Component reference
4. etc

[abstract delta]

I got you, that sounds much simpler

thanks all for your help.

[gentle urchin]

I cant see you unset is crouching ?

Ur setting it to true in both scenarios according to your links

[mint blade]

hey, where you say i must unset "is crouching?"

[gentle urchin]

When you uncrouch i guess

Either at the end of the transition or on key release

[fleet heron]

Hello. How can I get information to blueprint 1 that a collision has hit in blueprint 2? I can't figure it out

[odd kiln]

Use Blueprint Interfaces

[fleet heron]

oh thx! I will google it

[teal tendon]

Hey I want to ask how do I convert the Camera Component object reference to Camera Actor object reference any ideas

[royal badge]

Hi, i wanted to ask if there is a method of using physical in game buttons such as a button model to call an elevator, when i search online all i can find is widget tutorials, i have tried using on clicked events but they're very hit and miss and require the player to practically press their nose up to the model to click it.

[olive breach]

heya, i'm working on a dash system and trying to increase the camera fov when the player dashes. This is how i've set it up and for some reason the FOV lerps properly sometimes and then sometimes just nothing happens. any ideas on how to fix this?

[gentle urchin]

Sounds like your click is hitting something else

Had good success with mine when i set it up

[royal badge]

I think i figured out the mouse cursor wasn't centralised being an FPS style, so i had to lock the cursor to the center of the screen, only issue is i dont know how heavy this will be on performance as it is running on the tick

it works through that method

[frosty heron]

you don't?

[viscid viper]

hello i need some help for some reason my event dispatcher call didnt activated the binded event
pic one is my call for my allready binded event
second image is my binded event
does anyone knows why ?

[frosty heron]

what's the execution flow? Have you make sure to bind the event before Call?

do a print string after call and after binding

[pulsar vigil]

Hello guys i have a problem i can't resolve, i want to disable the capsule collision and all collision between my player and any NPC what would be the way to do that ?

[lofty rapids]

what is your collision settings on the player ?

[viscid viper]

Yes the bind come way before the call

[frosty heron]

show screen shoot of the print string

[bold plover]

you're binding the event even if its not valid, are you sure the same actor you bound it to is still valid?

[pulsar vigil]

on the capsule the collision preset is pawn collision enable

[lofty rapids]

so the collision presets is pawn ?

[pulsar vigil]

yes

[lofty rapids]

you may want to go custom, and ignore pawn

[pulsar vigil]

can i set this real time ?

[lofty rapids]

might work, it's worth a shot

[pulsar vigil]

im trying rn thx sir

[untold ivy]

How can I disable a bunch of nodes without deleting them? I had put the player perception directly ont the NPC blueprint, but while loading the game, I saw an advice that it's cleaner to put it in the AI Controller. I have move id to said AI controller, and I would like ot check if it worked, but I'd like to just disable everything while trying so I can fall back on it if I effed up.

[viscid viper]

Well its supposed to be but how can I check it?

[lofty rapids]

if you don't want it to run just disconnect the execution pin from the event

you can connect it back up if you want to use it

[untold ivy]

Correct... I am dumb. Thank you.

[rotund harness]

Hey everyone, does anyone know if theres a good way of seeing what portion of an actor is rendered? like in percentage or something... The only thing i found online was to like line trace to different points on the actor and see how many dont collide

[sharp python]

Every time I load my project, this struct changes to a Fallback Struct and then I get a compile error. 🤔

[untold ivy]

How can I get the actor from the AI controller? Moving this node to the controller means that "Self" is no longer the actor.

[viscid viper]

well its still valid

[frosty heron]

test it?

you are still executing the bind from the Is not Valid exec pin

so it is entirely possible that you are binding to invalid object

[frosty heron]

Probably get controlled pawn or something like that

AI controller should have a reference to the pawn it's controlling.

[untold ivy]

It does. Can I directly cast it to an actor?

[frosty heron]

why do you want to cast it to an actor?

cast it to your blueprint character/pawn class if you must.

[untold ivy]

Cause it wasn't connecting. But yeah, I casted it as the blueprint character.

[frosty heron]

read the error, be aware of object types

if you want to use function in the Character (Target is Character), then you can cast the source (controlled pawn) provided that the controlled pawn is a character type

[untold ivy]

It is. I'm going to have to figure out a way to use the right cast once I have multiple character blueprint, but I'll figure it out.... Or I'll come back to ask here ^^

[bold plover]

try putting the delay node somewhere else like in the other part of the sequence, and only firing reverse if its not already playing. Or if you just need it to reverse when its done you can do it off finished ofc

[frosty heron]

casting is just a type check

[untold ivy]

Is there an easy way to syncronise a variable between an AIController and a BP? Since the widget is in the blueprint but the variable is modified in the aicontroller, I was wondering what is the right solution to tie the two variables.

[frosty heron]

what bp and what BP?

the general rule is to never store any gameplay data in widget

widget job is simply to read.

your Character data should live in the character or some other entity if the data needs to be available when the character is destroyed

Get a reference to the object where the data live and pass it to widget

then widget just read straight from the object.

[thin panther]

https://tenor.com/view/obiwan-star-wars-obi-wan-gif-10973435

[thin panther]

Why have them separate. The widget should just be reading straight from what it displays.

If you have a widget tied to an ie, give it a reference to the AI, that it can then pull all needed info from

[untold ivy]

Sorry, I got distracted on another conversation. The widget is on my character BP and it reads a variable that is on the character BP.
But since I moved part of my logic into the AIController (notably the detection logic) it modify a variable in the AI Controller and not on the character.

[untold ivy]

The widget shows above the character. So I tied it to the mesh of the NPC. While I can attach a widget to the AIController (something I just learned) I can't attach it to the character's mesh can I?

[thin panther]

This is an unusual setup. the character should have their detection value, which the widget reads. Why would something else have that?

If an AI detects something, it should be modifying the detection value of whatever it detects

Preferably with an interface if it applies for more than just characters

Sorry if I'm not properly following with what the issue here is 😄

[young canyon]

Asked this in the general channel but no luck, trying my luck here as well.
In Lyra we have the IdleStance State maching outputing a pose. This is fed as input to the Output Animation Pose. Which should call function UpdateIdleState every update? But if I add breakpoint to a node in that function it never gets hit. Is there a way to have the ability to add breakpoints in these functions?

[trim matrix]

What I'm trying to do is get "Coin Number" from the BP Thrid Person, how do I accomplish this?

[iron stump]

i have an issue with the toggle movement node. when using the keyboard keys and USB controller, it works as should. it stops actor movement when needed then allows it once certain parameters are met. it however doesn't stop the onscreen buttons from moving the actor.

i need to block or disable the buttons for a single event, then resume once event has started

[thin panther]

You need to actually cast something to the character. A cast is a type check, not a way of getting objects from something

[grave relic]

Hi guys!
I'm looking for a keyboard key pack to put on the UI, but I can't find it, do you have anything?
I also couldn't find a channel to publish this message, I don't know where to put it...

[thin panther]

It's saying "is this ref i have of a more specific type"

[iron stump]

This is how i have the buttons setup in the HUD

[thin panther]

I.e., "is this vegetable a carrot"

[untold ivy]

No worries and thank for trying to help ^^
Basically, I followed a basic guide on setting up perception for my character. Everything in that guide happened in the BP_Base_NPC.
But as I have seen in the advice when starting my game, it said something that could be summarized as "Detection should be done in the AIController". Which is fine by me. Trying ot keep things clean, I moved all the detection logic from the BP_Base_NPC to the AIC_NPC_Base. It works fine. The only issue remaining is that since I moved the functions to the AIController, the variable actually being changed is in the AIC_NPC_Base while the widget is in the BP_Base_NPC.
Would the clean solution be:

1. Make a function to sync the Detection percent of both
2. Put a reference to the actor's variable rather than the AIC having its own?
3. Something else entirely?

[thin panther]

Detection should be handled in the ai controller, but the thing being detected should track how detected it is.

When the ai controller attempts to detect something, it should tell the thing it's being detected, which can respond by tracking it's detection value.

[untold ivy]

Thanks 😉

[hexed inlet]

These two BP functions. I made them both in the BP Editor. Why does one have that little white arrow, and the other not?

[cedar sparrow]

Is there a way to change the visuals on the EQUAL ENUM and NOT EQUAL ENUM nodes so I can actually see if it's an equals or not equals? This is borderline illegible.

I know it's because my value names are long, but shouldn't it just extend the length of the node

[lofty rapids]

are they both functions or is one an event ?

[hexed inlet]

Yeah I hate that

[hexed inlet]

Both just functions. If there's a difference in something I did making them, I don't know what it is

[lofty rapids]

show the two functions because it looks like ones an event

[hexed inlet]

I don't even know how to make an event

[pallid gorge]

Does anyone know why you can't call Play Montage on a skeletal mesh reference within an actor component?

[lofty rapids]

double click on the one that looks like an event where does it take ? show that

[hexed inlet]

They're both functions I made

I was making a guess that maybe it's showing functions that are changing member variables. But nope, not that.

Across my BP, I'd say the majority of its functions have that little arrow

[lofty rapids]

oh ya i made a function it shows like an event

i c that

[hexed inlet]

Mmm... But not all.

[lofty rapids]

i think it has to do with return values

because if you make a blank function it shows like an event

but if you add a return value

if shows like a function

[hexed inlet]

ah yeah?

Ah yes that's it. Nice

ty

Odd, since it's already obvious if a node is returning something

[trim matrix]

Sorry for interrupting. Could someone please help me? The array value is not setting :c

[fresh dagger]

Uhm, so I have a small issue. I have a made a construction script that makes a road follow a spline, I can move the spline, but the road doesnt appear at first. I have to find a small road part, move it and undo it so the new changes appear on the spline. How do I make it do it in realtime?

[lofty rapids]

your getting the values and modifying that @trim matrix

i don't think your actually altering the data

[trim matrix]

I see

Any suggestion?

[lofty rapids]

for one thing is the get a copy ?

[trim matrix]

that one I have is get by ref

[lofty rapids]

i would try to alter the struct somehow i haven't used struct much so idk but i believe the problem is you got the values and changing that array does nothing to the actual data

[trim matrix]

even tho I used get by ref? 😭

[lunar sleet]

That just means you’re getting the original value not just a copy of it

[trim matrix]

But that means I am editing the original and not the copy, right?

[crisp moon]

This can give exp but cant do from enemy

[lunar sleet]

From what I can tell you’re just trying to get inside that and copying it into Values

Probably easier if you see what’s happening if you set a breakpoint and step through the code, hovering over the pins as you go along

[trim matrix]

Ok, i'll try it on another way

[lofty rapids]

modify it directly

[lunar sleet]

Wonder how fast that bp struct will break 😀

[trim matrix]

Oh wait, it works now

[lofty rapids]

i think if you make a struct and don't mess with the actual structure and just keep it like it is or maybe add one but i can see where removing and if it's in use would break stuff

[lunar sleet]

It all works fine with cpp structs but dynamically changing bp structs goes very wrong most of the time

[white thicket]

what should i use instead of pawn sensing so that when the enemy sees the character he chases him. As both the characters belongs to same class

[lofty rapids]

perception

[white thicket]

https://cdn.discordapp.com/attachments/846520322642411570/1249039903921275031/image.png?ex=6665da8f&is=6664890f&hm=02a0b4313af768c00bc8cab4a81108057cc7b04a08b04a2ed8fd265e62a9d1fb&

[white thicket]

but how to use perception

which one to use?

[fresh dagger]

On target perception updated

[lunar sleet]

#gameplay-ai pinned video on Behaviour Trees covers it

[white thicket]

cannot perception be used without behaviour tree?

[lofty rapids]

you need stimuli source

and then that on update whould trigger, i would put it in the ai controller

thats what i used

[lunar sleet]

It can

[lofty rapids]

but ya like mentioned #gameplay-ai is best for that stuff

[lunar sleet]

I’m just telling you where to learn about it

[white thicket]

can't it run directly from here?

[white thicket]

okay

but for now i just want basic chase

actor with target actor didn't did anything

[fresh dagger]

https://youtu.be/iY1jnFvHgbE Try the official tutorial from unreal engine

[lofty rapids]

do you have a stimuli ?

[white thicket]

no

[lofty rapids]

so you need that on the player

and make sure its using sight

both should use sight sense

[lunar sleet]

#blueprint message

[white thicket]

on enemy?

[lofty rapids]

the way it works is the stimuli hits the perception

[lofty rapids]

definately check out the video posted

thats not what you want

[white thicket]

Okay

[trim matrix]

so you are telling me that you set the AI's position to 0,0,0 on tick? lol

[lofty rapids]

heres something i got some help here with awhile ago

lol it looks f'd but it works to clear the actor

[lunar sleet]

You know it might be easier to make it loop and on false clear and invalidate the timer

But that may require some testing, I can’t really compute it in my head rn

[lofty rapids]

ig i could make it looping and clear and invalidate afterward

[trim matrix]

it will always be true?

an index can't negative

in BP

[lofty rapids]

-1 means it didn't find anything

so if the find comes back -1, the character isn't in the array

[trim matrix]

mhm

[lofty rapids]

its a way for the blackboard to forget the character

basically when the sight lifetime runs out then null the player in the blackboard

so he no longer chases and goes back to wondering

[lunar sleet]

You can also use on target forgotten, just gotta enable it from project settings

[lofty rapids]

where is this setting ?

[trim matrix]

how could i make a depth render in game so u can see the players shadow through a mesh like this?

[lunar sleet]

Can’t recall off the top of my head. Somewhere in project settings afaik

[cobalt plover]

I just started using the Common UI plugin, and I'm getting an error where every time I launch Unreal that one of the blueprint functions in Common UI fails to be found. If I delete and re-add the function it works just fine.

I have a hunch that this isn't specifically an issue with the Common UI plugin, but an order of operations when initializing the editor. Maybe this widget is initializing before the Common UI plugin loads? Has anybody encountered an issue like this and found a solution?

I just installed the plugin and started working with it without trying to find any documentation, so it's also possible I'm just using it wrong 🙂

[maiden wadi]

It's an order of initialization issue. Are you using a C++ project?

[cobalt plover]

That sounds right. Yeah, it's a C++ project

[maiden wadi]

You should be able to add CommonUI as a prereq to you primary module to fix it.

[cobalt plover]

Ah that makes sense! Thanks 🙂

[ember lichen]

How can I find the affected BP? It doesn't say which one

[cobalt plover]

Hm, so this is my first C++ project, I've been working in BP up til now.

Is adding it as a prereq just adding it in Build.cs, or should I be doing it somewhere else? Adding it in Build.cs doesn't seem to have solved the issue

[maiden wadi]

You can try the nuclear option of adding it to your UProject and setting it's load order to an earlier tier.

[somber elbow]

Hey guys! Im trying to build difficulty changing logic for my game. Its a platformer game. And the idea is the higher player gets the less platforms will spawn. For difficulty change i have a variable "height". So when its 10 the difficulty changes. Just as an example. The thing is that using branch every tick may be too expensive. How can i optimize it?

[spark steppe]

check the height when spawning new platforms?!

[somber elbow]

yeah

but right now it checks every tick

and it works

[hollow cove]

wtf

wherever they change difficulty use that to change whatever youre changing

[somber elbow]

but it checks it every tick

[spark steppe]

ofc it works, but why don't you just check the spawn height?!

you spawn anyways at some point, so might aswell check the height there

[hollow cove]

https://cdn.discordapp.com/emojis/1099812136580038736.webp?size=28&quality=lossless

[somber elbow]

yeah i have height variable and it checks it. I just dont want it to do it every tick

[spark steppe]

siempre apareces en algún momento, así que también podrías verificar la altura allí

[hollow cove]

what am i looking at right now

[spark steppe]

the same message as before but in spanish

[hollow cove]

where are you changing the variable height??

[somber elbow]

in another blueprint

[hollow cove]

so change the other variables here too?

show me

also height * 10 = difficulty something limit

and (height * 10) + 150 = difficulty upper limit

if it keeps going the same

[somber elbow]

@hollow cove @spark steppe

[lofty rapids]

why don't you run this when you change the variable instead ?

[somber elbow]

i dont know how. Create custom event?

[lofty rapids]

when do you change the variable ?

is height where your player is ?

[somber elbow]

so you think its better to move it to the blueprint where height variable is beeing changed?

[hollow cove]

yes

[lofty rapids]

i would fire it off when height changes, since thats all the code is checking

ya a custom event, then just call it when you change the height

this way if it's 10 it will just run when you hit 10

[somber elbow]

I have never created custom events

so yep I believe my bummer is here

[hollow cove]

right click in the event graph

type custom event

[lofty rapids]

it's fairly simple

[somber elbow]

Got it. Makes sense guys. Thank you!

[lofty rapids]

you could also hook it up to a sequence to make it a little shorter

instead of scrolling over for everything you get some up and down

is there a way to only keep specific pins

i thought i have seen that before

so for instance if i only want 1, 4

but i don't want any others

it seems like i can only remove the last pin

[somber elbow]

Im trying to create custom event and i dont quite understand what will trigger it. I mean i do understand thgat it has to shoot every time when "height" is 10 but what will check it? Will it be then the same logic where machine check for height=10 every tick?

[lofty rapids]

when do you increase the height variable ?

when you increase it, check if it's the numbers you want

you can keep it on the same bp as i'm guessing the variable for height is on there

is height specific to each floor ? or height is where your character is ?

[lofty rapids]

i only got switch on int

[inland crystal]

Yes, you need to download the plugin I made to use the extra nodes I added 🙂

I mean, it's free, in the link I just posted, I'm not selling anything.

[tropic pollen]

okay, so I have a wheel, you spin it and based on where it lands, it takes you to a place (new level). how do I get it to spawn me at the choice it lands on and not a random selection?

[lunar sleet]

Do you have a player start actor ?

[lofty rapids]

what is choicearrow ?

[tropic pollen]

yes I do

[tropic pollen]

th long tiny box at the top

[lunar sleet]

Hold on, are you asking about a place in the level or are you saying the wrong level gets picked?

[lofty rapids]

so at what point does that run, when the balls collide with it ?

it looks they are rotating the thing, but then on some sort of collision picking a random number

and i think they want to link the two

[lunar sleet]

Oh lol just noticed the random int in range

Why switch on int random if you don’t want it to be random?

[tropic pollen]

wrong level gets picked.
when the wheel stops spinning, depending which box it stopped in, thats the level it should go to.
yeah I don't know what to put to link the two
because I don't know what else to put.

lol

[dawn gazelle]

Assuming the collision actually does work as you're expecting.

[lunar sleet]

Yep

[lofty rapids]

i would have a collision on the picker or somewhere at top, that set the current one it's on, then on timeline finished the one it's set to is the one to pick

like when the balls collide, set that as the current pick

[tropic pollen]

I had tried that but it always lands on purple so I guess my collision is the issue?

[lunar sleet]

More than likely. Check to make sure the collision shapes aren’t overlapping each other

[true valve]

How can I have physics actors not to collide with each other to avoid getting stuck? I have physics actor boats.

I want them to go through each other..

[tropic pollen]

they were overlapping, but arent anymore but sitll doens't work.

[tropic pollen]

not sure what you mean, a collision on the collision for the collision ?

[lofty rapids]

well when does the long pin one fire off ? everytime a ball hits it ?

[warped juniper]

Ah, as always a better solution is right there to use lol

[lofty rapids]

you want when the ball is at the top set that as the current one, you could just have integers mapped to the components

[tropic pollen]

after the delay is when it fires.

[lofty rapids]

no the overlap event

where you goto level, when does that fire ?

on the first hit i'm guessing

[tropic pollen]

yeah first hit

[lofty rapids]

if you put a collision box at the top, if have one use that, but you checked the balls that hit it and set the integer accordingly, then on finished you would have the last one that collided with top

[lofty rapids]

right each time that a ball hits that thing set the integer based on which one it hits

hopefully only your balls are colliding with it

but it shouldn't matter ig

[tropic pollen]

my balls dont actually collide, they are temporary so I can see which collision is what. the big collision squares collide with the long rectangle at the top

[lofty rapids]

ok

so use those

you could on each one set the integer on collision with the pole

so that at the end of the timeling the last one colliding should be the one that is at the top and picked

so you wouldn't run that code on collide, but on finished of the timeline

and instead of picking random

use the variable that you set on the collisions

[tropic pollen]

4 different variables for 4 different collision, what do I do about that? how do I plug that in?

[lofty rapids]

one variable

that you set on each collision

so when one of those boxes collides with that pole then you have entered that section

set the integer to the correct one for that one

so on overlap of each one set the integer to it's corresponding value

and then use that integer to plug into your switch

[lofty rapids]

4 events, one variable

[tropic pollen]

omg I understood you! it works!! but now I broke the random and it lands on the same one each time... lol\

[tropic pollen]

thank you so much for the help 🙂

and your patience

[lofty rapids]

so the selector works but your not rotating a random amount ?

[tropic pollen]

no its the same one each time but it does rotate

[lofty rapids]

what does your rotation look like ?

[lofty rapids]

it should still be random float in range, make sure you have the proper min, max plugged in

[tropic pollen]

yeah its plugged in. it stays within about 1/8 of the place it lands on

timeline is only 1 second, min is 2 and max is 5.

[lofty rapids]

thats a small gap for a variation

[tropic pollen]

okay i put 1-50, its btter, a bit high but i'll adjust later. THANK YOU!!

[fiery ridge]

I need to get a random element from a structe array that only has TRUE booleans in it. Anyone know? The ForEachLoop body doesn't loop randomly, it always start from 0, right?

[lofty rapids]

arrays are usually zero indexed

so zero is the first index

wdym "struct array" ?

an array of structs

[fiery ridge]

I have vector + booleans in the struct

Each vector has a bool

[lofty rapids]

so you want a random vector with the boolean true ?

[fiery ridge]

Yes please

[lofty rapids]

do you need a reference to the thing, or just a vector where a true boolean matches ?

[fiery ridge]

Second one

Whatever is easiest I guess

there's a shuffle but not quite sure how to target specific elements

[lofty rapids]

might not be the best way

but it's a way

[fiery ridge]

Ok so u add if it's true, I can use that for a single vector instead of array

kind of "filtered" vector

Thank you i'll try this

[lofty rapids]

just be careful on a big struct array

it will be slow and could infinite loop

but thats just bp

[fiery ridge]

Oh yes, never had this many infinite loops hah

[lofty rapids]

ya bp needs to do it in one tick or your f'd

[lofty rapids]

if your doing a single vector, where there will only be one with true

use a foreach with break

and break when you find it

instead of looping through the whole thing when you don't need to

[fiery ridge]

It's my first time going deep with arrays, it's giving me headaches lol

But im getting there

[noble ledge]

Is it possible to see what object has a reference to another during runtime? Trying to see why a widget isn't getting garbage collected.

[mild rapids]

I have a animation notify which is detecting collision on the foot from a kick animation. Once I have the collided object, I am storing the hit. I now want to apply some impulse to the object that was hit to have it move so it looks like the object was kicked however, when I apply impulse, it seems not get 'kicked' in the direction the leg is kicking it
This is what I am currently doing:

[lofty rapids]

"the normal of an impact point is the direction of the trace." @mild rapids

you may be able to use the normal and multiply it by some amount

right now your adding an impulse that is the impact point which you probably don't want

[stiff tendon]

Hi! @engage has it right. Your impulse vector is the hit location, which isn't right. If you want to apply the impulse at that location, use the AddImpusleAtLocation instead. You still need to send an impulse vector though, so a vector that points toward the direction to move to and which magnitude equals the impulse's strength. You likely can use the bone's velocity for that

[craggy flicker]

so for some reason my default bp thirdperson became data only when I moved it to a different folder, now I can't make any modifications like deleting the camera boom

how can I fix this?

[lunar sleet]

Show issue

[craggy flicker]

i had to reparent

also i couldn't really show it without giving more information i already said lol

[pastel apex]

question how do i remove an element from an array in an editor?

like for example if i accidentally added an element to an array on the editor, how do I remove it without clearing out the entire array?

[lunar sleet]

There should be a little drop-down arrow

[pastel apex]

ah ok thanks

[elfin gorge]

This is a general kind of question. I'm trying to create an SRPG camera where the camera would pan to the direction of the mouse based on where its position is to the border of the screen. Would it make more sense to create a series of functions in blueprint or use the enchanced Input System?

[floral stump]

in which ini file i can set these resolution?

[floral stump]

DefaultEngine.ini

[ScreenResolution]
ResX=1920
ResY=1080

[queen dagger]

ok

so

i have this notify that is called on attack it does damge and i want this to knock the character it damages back

i want to add the launch character but i cant seem to get the character from the output of hit actors

what should i do to get around that

[lunar sleet]

Cast

You already have the ref. You just need to check it’s a char

[queen dagger]

gotchu

cast after the apply damage right

itsworking lol

now i need to set roation to be opposite of the damage incoming which has been more tricky i tried setting a set relative rotation but everytine it just rotates it 180 degrees

[trim matrix]

Is Apply Damage deprecated? 🤔

[queen dagger]

deprecated?

[trim matrix]

yea..

[queen dagger]

i dont know what deprecated means in this instance so im assuming no

[trim matrix]

meaning that it's not recommended to be used, since they will not update it further on

[worthy jasper]

dont think its deprecated no

and deprecated means its being removed in a future update

not just that it wont be updated

[queen dagger]

ahhh

[worthy jasper]

guess it could mean both

[trim matrix]

um no? the input key system before is deprecated but still work in 5.3

[worthy jasper]

where it say deprecated

and remvoed doesnt mean the next update

[trim matrix]

everywhere wut

[worthy jasper]

it just means it CAN be removed

interesting

i mean enhanced input is the way to go anyway

unless your debugging

[trim matrix]

@thorny narwhal sorry for the ping but you are the one who told me it was deprecated, just making sure now...

[worthy jasper]

sure there is a doc about

probably never noticed XD

[trim matrix]

lol all good

[queen dagger]

for my game im using 5.3 still so idk if it really makes a diff

[trim matrix]

I'm still using it for now, looking forward to create my own system

[worthy jasper]

i mean enhanced input really makes it easy to let players rebind keys

so that alone is worth imo

[queen dagger]

wait are we talking about apply damage?

or EI

[trim matrix]

both

[queen dagger]

oh

rip me

least im already using EI

[trim matrix]

good

[queen dagger]

but i still need to figure out how to set the rotation based on the damage event

is that even possible tho

[trim matrix]

probably from the normal hit if you have a line trace or smt like that

[queen dagger]

im using box trace

[trim matrix]

(I have no idea what's the context here)

[queen dagger]

character using this notify to apply damage and i need it to set the direction of the character based on which side the hit is dealt

top is if youre on the right and so the actor getting damaged should face left and vice versa

[trim matrix]

but with words, what's going on and what do you want to achieve? (is the bullet an actor)

[queen dagger]

if the left attacks the right, right will turn to face the character that hit them

[trim matrix]

okkk so you could just flip the character 180 on the z axis?

[queen dagger]

i tried but every hit it will flip it 180

so after two hits itll be facing the wrong way again

[trim matrix]

then check if it's already in the correct direction, if not then add 180, if yes then do damage but dont change rot

[queen dagger]

ok

[frosty heron]

copyright strikes everywhere 😅

[trim matrix]

wdym

[frosty heron]

look above, it's naruto characters

[trim matrix]

truee

didnt realize

[queen dagger]

shhhhhhh

but still no luck with the roation set

[trim matrix]

it doesn't work?

[queen dagger]

for some reason i cant get the rotation to change maybe im doing it wron

[trim matrix]

does it work the first time?

[queen dagger]

not yet

should i need to do another cast

[trim matrix]

ofc not

what happens then

[queen dagger]

just a hit animation and the rotartion doesnt change

[trim matrix]

do GetActorRotation and then set it to the rotation + 180

also, maybe it's not the Z axis, I'm not sure but it should be

[queen dagger]

thats what i have

this is the result

[trim matrix]

from the result pin blue, get rotation

[queen dagger]

and i just noticed its not replicating

ugh

[surreal peak]

Given you can probably attack from both sides, you will need to calculate the rotation

You can math out the direction from attacked to attacker.
Then use MakeRotFromX, split the rotator and check the yaw value. You might need to round it to the nearest multiple of 180.

You might want to do the rotation stuff in the character that got attacked instead. Cause if you ever have non characters like a box that you can attack, it would also flip

[heavy plinth]

Hey is there anyone who can help me figure out what's going on with my animation blueprint? I'm using the enhanced input to change the crouching variable to true which should activate the crouching idle pose. It looks like it does but in-game the player only crouches when moving around

[rotund harness]

Hey, everyone, i tried asking on materials but im not sure thats the right place, does anyone know if there's a way of using a post process material only on a scene capture? With it not being visible to the player I mean

[hoary summit]

im getting an unsafe thread call when casting to my pawn from my anim BP

does anyone know how to fix this? it works as intended but id rather not have the warning.

[gaunt monolith]

Hello, what am i doing wrong here? want to reset the Do Once node every time the Update Date is called

[dark drum]

Using the 'Get All Actors of Class' is probally contributing to you're issues. If you have multiple 'BP Weather Tower' (which I assume you will), it'll only ever reset the interaction on the first one it finds, of which isn't always going to be the one that was interacted with.

[gaunt monolith]

oh yeah, that's probs the problem i guess, is there a way so that it resets in every weather tower?

[dark drum]

What dictates when the interaction has ended?

[gaunt monolith]

i just interact with the screen by clicking the left mouse button, the screen shows random numbers in a range and that's it, i want the players to be able to click the screen and get these numbers once a day bsically

[lavish finch]

Is there a way to determine if an input action has been activated while the character remains within a collision box using blueprint?

I attempted using the boolean node within the player controller function but something went wrong.

The collision is stored in different master blueprints where their child blueprints carries different gameplay tags.

I want to transfer the specific gameplay tag to the gameplay tag container stored in the game mode when the character collide with the child blueprints and player trigger the interaction action input

[viscid viper]

hello ive been stuc on it since yesterday and i still cant figure out why the binded event didnt get activated
the object is stil valid and the i first bind the event and the call it
the only thing that i changed is that ive created another objects of the same class but i never run the code that leads to the bind on them so im completly lost anyone got any idea ?

[frosty heron]

my idea is that you never bind the object or at least never bind the delegate to valid object

in your screen, even when actor is not valid you are still binding the object, for what?
I gave you tips earlier to print string and drop the is not valid node, until I see evidence that you bind before calling then it's not possible to help.

[twilit granite]

Widget Switcher was removed?

I am using 5.3

[mild jacinth]

can someone explain to me why this doesnt actually update the health smoothly, and it doesnt update at the correct amount added either

it adds like around 48 points each time but current health is 2500 and the amount to add is 1000

[frosty heron]

make it less spaghetti

[mild jacinth]

ok, wait

[frosty heron]

You shouldn't be changing the values either. Interp works from A to B

if you change either of them in the middle, you will not get the result you want.

[frosty heron]

For one, Interp should happend on Tick

So you should move this codes to be run on Tick

It is as simple as Interpolating Current Health to Target Health

Your increase Health function should be
Target Health = Current health + Amount

that's all there's to it.

[fringe oasis]

Does anyone know the benefit of using instance structs?

[twilit granite]

Using structs and classes you can avoid this kind of situation

You can organise many information in a single place

[mild jacinth]

I have used World delta seconds before without issues. I also tried using custom event with timer handle, it still doesnt work

[mental trellis]

Polymorphism for structs.

[mild jacinth]

it either goes too high value(5000+ to currenthealth variable) or it just adds 40 each time

I have tried setting a check 'currenthealth >= finalvalue' but it somehow doesnt work

[frosty heron]

That's not the issue??

but if you are not taking advices then I don't know what else to say

[mild jacinth]

I mean I tried it on tick right now

it goes over 5k

[fringe oasis]

I ll research about that topic, ty.

[frosty heron]

Show code

[frosty heron]

why are you still adding in the same function?

in tick nonetheless

please read above

your tick function only interpolate from Current To Target. That is IT!

Create a new variable called TargetHealth

[viscid viper]

The object is valid

[frosty heron]

won't know without evidence

many times people say something when it's not the case is usually the problem

Stop binding it when it is not valid, why do you have your exec pin on not valid to connect to the bind to begin with. The most it can do is print, Object is not Valid Please FIX

[viscid viper]

is that enough evidence that it is valid?

[frosty heron]

Print string when you call the delegate

then screen shoot the result from Play In Editor

[frosty heron]

print here too

if it does print then your event do get executed, if it doesn't, you want to check if the blueprint instance is not destroyed and exist in the game

[viscid viper]

it doesnt execute

wait it was destroyed for some reason

but why? like i didint override it and there isnt a code anywhere that it will delete it exept for after it execute the binded event

[frosty heron]

ctrl Shift F and type destroy actor, then click the binocular icon. Skim thru the project to see where you possibly destroy it.

[viscid viper]

the thing is i dont have a destroy actor for it
it is a c++ class of Action : public UObject, public FTickableGameObject, public IVisualLoggerDebugSnapshotInterface

[frosty heron]

an object will be garbage collected if it's not reachable

make a TArray of your object then every time you construct a new object and add it to the array

that should keep it alive

actually you probably just need a valid outer

If the actor that spawn the object is gone it will probably be gone with it. Keep the actor that spawn the object alive and it should stay alive imo.

[viscid viper]

it kinda what i do the object is allready inside an array in a struct that itself is in an array what im trying to do is when another struct is born compaire the struct with its array of obejct to the rest of the struct and only if it isnt identical add it to the struct array

so my array of object til now is in an array inside a struct but both dont get destroyed at all
