[trim matrix]

If you were trully disabling collision on the player, he would be falling through the word wouldnt he?

Is it even a good idea to disable player collision? no

Disable the enemys collision when you pick it up

and on the enemy what would you say to disable

You would need to check exactly the componets your enemy has. Id assume the root capsule componet and the mesh componet for sure.

You may have more though, I wouldnt be able to tell you how your enemy is set up.

so the only stuff that could be collision is the weapon actor, I've just disabled that collision and the mesh and the capsule

You might need to confirm that the weapon actor and all of its componets dont have collision as well.

yea

nop still throw player like off elsewhere

Did you confirm you are launching the right character?

I am really starting to think it's the attaching and detaching

I cannot tell from the screenshots.

yeah Im launching the player character

it's passed in when grab target is called

Wait your trying to launch the player?

Dont you want to launch the enemy?

the capsules also ignore each other

[trim matrix]

so the enemy the bot picks up the player

Oh i see.

launches player

Sorry in that case, you would need to disable the players collision yes.

But more then just the mesh still

You might want to set its movement mode to flying as well.

Also in that case, you would probably want to set the rotation rule and scale rule to keep world.

On the attach actor node.

[trim matrix]

I was thinking that tbf

I've had to do that for something else

Just make sure to set it back when you detach the character.

so would set actor enable collision not work ?

like to just globally set everything to no collision I would think thats what that function does ?

I normaly disable it one component at a time. Never used that so idk.

[hoary junco]

I have a moving searchlight that looks something like the screenshot currently, but I'm not happy with how it looks, I'd like to turn down the opacity of the cone while drawing a circle on the ground where the searchlight makes contact so it's obvious to the player where the outer bounds of the searchlight is, how would I go about doing this?

the solution Eddy gave earlier didn't really do what I was hoping for

[trim matrix]

@trim matrix so this is my attach

everything look right there you think ?

[trim matrix]

can you not do it with material and fresnel

Is this code inside the enemy BP?

[trim matrix]

yeah

[pulsar vigil]

what is ur problem resumed ? cause i m using attach and detach like crazy for few days now i may be able to help

[trim matrix]

reason is makes it easier to customse for each enemy

[trim matrix]

bassically when I launch my player from the enemy bot with the attach stuff in and detach stuff in

[hoary junco]

what's fresnel and how would you use it for this purpose? sorry I'm kinda new to UE5 and haven't messed with materials much

[trim matrix]

my player gets put off elsewhere

and then if I remove the attach and detach stuff it works how I would expect obvs player isn't attached to enemy hand and thus doesn't go along with it but

[lusty ginkgo]

is there a way to make certain branches of a sequence node have higher priority than the other?

[pulsar vigil]

when the player is detached the player is not where he should be ?

[trim matrix]

sequence nodes execute from top to bottom.

[trim matrix]

well kind of let me find the video

[lusty ginkgo]

k, so the one at the top is the one that is the higher priority?

[trim matrix]

yes

@pulsar vigil

[lusty ginkgo]

k thx

[trim matrix]

well it executes first.

[hoary junco]

there's a little red thing in the corner of each node that shows you the execution order I'm pretty sure

[trim matrix]

so thats when I try have attach and detach stuff in there I get that

[lusty ginkgo]

k, I'll see if there is

[trim matrix]

This is when I remove the attach and detach

[lusty ginkgo]

there is not a red thing on each node

[pulsar vigil]

and u want the attach and detach cause u want the ennemy to grab and block ur movement ? @trim matrix

[trim matrix]

so grab

idea is I can have the enemy grab player by neck for example lift and throw them back

[hoary junco]

you're talking about behaviour trees right? in terms of sequences and selectors?

[pulsar vigil]

cause the issue seem like its ur detach

[trim matrix]

I agree

[pulsar vigil]

but i dont know how behave the thing u made to push ur player

[trim matrix]

it's like when it detachs where it should be isn't actually where it is

if that makes sense

take the actor

[pulsar vigil]

maybe its an interaction with the way i push it assumung the detach is working fine

[trim matrix]

the player actor and lunaches them

which works fine as I say without the attach and detach

They are the setting of the detach

[pulsar vigil]

a solution im thinking of is u should try the detach without ur push

[trim matrix]

There the settings of attach

[pulsar vigil]

then if it work fine add a delay but that might be the best solution

[hoary junco]

you see these circles in the top right corner of each of the nodes?

[trim matrix]

the player won't be launched then

oh I get you

[pulsar vigil]

yeah but to verify

if the detach attach work fine without

[trim matrix]

so progress

the detach is working fine

[pulsar vigil]

is not talking about those sequence i think

[trim matrix]

it seems to be when the detach is used in connection to the launch player character

[pulsar vigil]

ah yeah maybe add a short delay

[lusty ginkgo]

I am in the blueprint editor and not using the behavior tree

[trim matrix]

it's like a one or the other but not together haha

[pulsar vigil]

try a delay i dont know why it could not work like this

[hoary junco]

oh ok nvm then

[trim matrix]

wait

[lusty ginkgo]

thx anyways though

[trim matrix]

i never had attach connected

[pulsar vigil]

lmao

[trim matrix]

the detach is the issue

when it detaches it seems to set the player off elsewhere

[pulsar vigil]

is it in world position ?

[trim matrix]

yeah

well

attach is keep relative

detach whether I do keep relative or world I get same result

[pulsar vigil]

arf

[trim matrix]

Is that cone a static mesh?

I can't really do snap to target either else it'll put like mid of the player to the enemys hand

[hoary junco]

yeah, it's just a cone component slapped onto the model and given a translucent material, the component is important though because whenever the player character overlaps with it then it triggers something

[pulsar vigil]

and the attach and detach without the launch work ?

if the attach dont change ur position its working fine i think its ur detach

[trim matrix]

nope so the attach and detach without launch end with player off way to the side

[trim matrix]

I'm pretty certain it's the detach but I don't see how I can do anything with that

like how thats even fixable

[hoary junco]

I had considered just putting a really thin cylinder component a certain distance away from the searchlight but, the light's area touching the floor could change depending on angle and it would look really cool if when the cone crossed over a wall that you see the circle on the wall too, kinda like how a flashlight beam works

[pulsar vigil]

ur detach should work its physique or something else that influence the transform i guess

[pulsar vigil]

u can always track ur position and detach the actor at a specific place but thats weird

[drowsy kestrel]

Hi i made a reload and ammo system but this wired glitch happens. Whenever i hold the left click button it doesn't count bullets. A kind person helped me but there fix didn't work.

[hoary junco]

I considered a spotlight too but I can't get it to hard cut off at the edges it fades out as lights tend to do

[trim matrix]

Hm translucent materials get rendered after all opaque materials and get slapped on top of the world. Creating a material that would change the floor colour seperatly from the rest of the material would be difficult. Id imagine you could by comparing scene depth.

That would be complicated though.

A simpler solution would be to apply a decal to the world, or use a spotlight.

[hoary junco]

how would I apply a decal?

[trim matrix]

well this is thing there isn't anything that would do anything wierd

[pulsar vigil]

yeah and u could even influe the scale of it with the vector lenght or something but dont uhave to trace ?

[carmine palm]

Cant you just apply an emissive?

😐

[trim matrix]

Just by moving a decal actor around where the center of the light hits.

[carmine palm]

so it still has light effect

[trim matrix]

An emissive what?

[carmine palm]

a circular plane with emissive material

(no idea what a decal is)

😛

[trim matrix]

If the area was completly flat, that might work.

[pulsar vigil]

are u in movement falling from the ground when it happen ?

[carmine palm]

oh true

[trim matrix]

Any bumps would ruin it. Thats where decals come in.

[carmine palm]

so decal follows mesh?

[trim matrix]

They project onto the geometry.

[carmine palm]

thats badass

[trim matrix]

techincally yeah as the player actor is lifted off the ground

[carmine palm]

learned a new thing again 😛

[trim matrix]

I have an idea

[pulsar vigil]

thats nice

[carmine palm]

No collision?

I'd assume

[pulsar vigil]

cause that look like the player is tp to the origin of ur level

[trim matrix]

no origin of level is other side

[pulsar vigil]

xD

[trim matrix]

origin is over to the left

[hoary junco]

would the decal deform based on the angle of the light radius? like if the light cone was closer to the ground would it stretch out?

[trim matrix]

it seems to end up player to the right of the enemy

For the spotlight, you can also use light functions to have further control over exactly how the light works. Its like a material shader for the pixels of light.

[trim matrix]

You would need to manualy program that.

Can just check the distance to the ground and stretch it.

[pulsar vigil]

that look like a collision issue if u disable collision on ur player before the attach

[trim matrix]

In the end, unless your making a super complicated material shader, you will need to use that method of stretching some sort of plane/decal over the ground.

Or light ofc.

[pulsar vigil]

if u are falling it cannot be something else

[trim matrix]

Yep I'm doing that

[trim matrix]

What I'm thinking is when it's lifting player up is it somewhere offsetting so when it detaches the player actually is off to the right and not where they end up

I tried just attaching and detaching player mesh but that also failed

Player ended up at world origin

[pulsar vigil]

if u let the player detach without collision i would not be surprise that it fall for sure

u tried to set the collision back ?

[hoary junco]

so, I went with the spotlight in the end because I realised by setting the inner and outer core angles to the same value I could get the light to basically be a flat colour and give a hard border to its outside edge instead of fading out

thanks for the help

[trim matrix]

So I was

But to check if detach is the issue I did try it where I never re-enable the collision

[hoary junco]

wait, I just had a thought... can light generate overlap events?

[pulsar vigil]

trace hit, i think

[trim matrix]

I'm gonna return to issue tommorow anyway

[pulsar vigil]

ok

[trim matrix]

Brains like done for this evening ahah

[pulsar vigil]

thats a good idea to let him work and breath while sleeping

[hoary junco]

is there a way to move the pawn sensing component? I've come to another realisation, which is that the current way I'm doing detection is with a cone mesh that comes from the character and detects overlaps, however that cone can go through walls and detect something on the other side and I don't want that, so I learned about pawnsensing instead.. but the issue is when I put pawnsensing onto my guard, it's stuck above the model and I can't really move it...

[jade coral]

Hey everyone, apologies for asking yet another question.

I have it set up so players can connect to a lobby, which then the host/server can change the settings of it and then start the game (wherein they load into the map and the gameplay loop goes through before after the game ends they all go back to the lobby). My question is how would I communicate variables between levels? Like how could I have the variables set [or rather the game settings set] in the lobby, be carried over to the new level? [And potentially vice versa if I wanted to have certain stats tracked/displayed for fun in the lobby like who died first etc]

(also im using advanced sessions, using steam API for the networking socket, and CommonUI as relevant plugins... just in case lol)

[lunar sleet]

Probably save them in the GI, but for #multiplayer i’d recommend moving to that channel

[jade coral]

ty ill do that ^_^ someone said something about the session extra settings

[carmine palm]

Replication is only for multiplayer correct? (server/client interaction)

[foggy basin]

I'm making a system to pick up objects with physics, but when I place the object below my character and move the object, we go flying off into infinity and beyond. It seems to be a common bug for this type of system.

[carmine palm]

mmm physics

try removing add impulse on damage

[foggy basin]

unfortunately it didn't work

https://gyazo.com/4358aa30749c496e03fa7d28aac4ebb1.mp4

[stiff swift]

The item is hitting you

Make it ignore collision with player or on pickup disable collision

[carmine palm]

or that

[stiff swift]

There's a few ways to go about it

[carmine palm]

lmao

or figure out actual physics

mass per item

etc

[stiff swift]

True making it .01 should be light if the players heavier xD

[carmine palm]

^

except player will kick it to the void

[stiff swift]

Myte also be able to temp disable physics depending on what you do with that item

Then re enable on drop or smth

[lyric pumice]

Hey, guys! This is my BP that makes my camera follow my character through a spline and the second one makes another camera look at my character, someone knows how can i make to join the 2 functions? Slide through a Spline looking for my character and just one BP? I've tried somethings but no successeful results yet.

[carmine palm]

Just bought electronic nodes and darker nodes sooo

we will see how it looks

Its so good

[slender quest]

Is there a way to use blueprints to create a simple online leaderboard system for an indie game?

[frosty heron]

No

But there are plugins where you can do http request

You can make api call to get and set the scores

Would still need to code the back end tho

[slender quest]

ah damn, but then is there a simple way to use C++ to make a simple online leaderboard system for an indie game?

i can search for tutorials if so, but just wanted ot know I should give up on a bp solution

this might be the push i need to finally learn C++ on UE

[frosty heron]

Almost everything is possible with cpp. But I don't know what suggestion I can give you. I know little to no cpp

Personally I would just use the steam or other platform api for such feature.

[sullen hinge]

Hey guys! Having an issue rn with some collisions. Basically this is what is supposed to happen:

• Player shoots a bullet at an enemy (working)
• Enemy finds a nearby enemy (working)
• The bullet spawns another bullet at the first enemy's receiver and the bullet is supposed to move. (not working)

Right now it can spawn the bullet, but the bullet doesn't move. I'm using the built in Projectile Movement Component.
I already tried using an "Ignore Actor when Moving" node and passed in the parent collision component and to ignore the Owner which I already set when I spawned.

Anyone have any clues why my bullet doesn't move on spawn?

[frosty heron]

@slender quest perhaps there's a plugin for such thing, I don't skim the marketplace for very long time. But I am not aware of any online leader board in blueprint out of the box in unreal

@slender quest https://youtu.be/_9W_WtfAojc?si=ckdZXEt7Ll3mWUa7

Looks like there is something you can use without diving to cpp.

Would still recommend learning cpp tho, there are power to be harness from using it

[slender quest]

Thanks for that suggestion, I will take a look at it!

But yes, CPP is something i really need to get learning

I just have been able to get really far with blueprints for now and I get a little worried that it may take me a long time to learn CPP

[hushed ferry]

it will take a bit of effort ye

but well worth it

[magic mica]

I have a door that resizes your PC and the door when you walk through it. The Doors mesh and collider boxes all shrink, but for the PC only the mesh will shrink, the boxes and all related components stay the same. The door has "cast to third person character" in it.

[faint pasture]

Show your code

[magic mica]

One sec please.

Here you go. @faint pasture

[sullen hinge]

Just want to push my question up in case it got buried!

[magic mica]

How are you shooting the bullet from you PC? Do you have something like an Arrow? Does that get generated on the enemy for it to have a vector?

[sullen hinge]

Ahh got it to work

i was just fixing up some collision channels and presets and then used the Ignore Actor When Moving

[sullen hinge]

thx hto!

[faint pasture]

my dude you need some functions or events

[magic mica]

Ive only been doing this like 2 months. Any suggestions for resources would be appreciated.

Okay, I have found out how to resize the capsule, but it always scales to much. I am thinking I need to spend some time on youtube.

[faint pasture]

Start with making an event on your character, call it ChangeSize, passing in a float Size

when the thing happens, just call ChangeSize

you can test ChangeSize by calling it on button presses etc

[magic mica]

I will give that a go. Thank you.

[magic mica]

This works, and is a lot cleaner looking. Would it be better to have the Event in the Third Person Blueprint, or in the Doors?

[wicked violet]

anyone know how to do quadruped movement in blueprint (so turning circle/radius)

[faint pasture]

In the 3rd person character BP unless the doors are the only thing that'll ever be making the dude grow and shrink

[magic mica]

Thank you.

[wicked violet]

its honestly kind of amazing how little documentation there is on this. Or when there is documentation its very vague.

[magic mica]

Like when you are on a horse or in a car? If forward is the direction the camera is pointing, can you link the rotation of the camera to your controlling keys?

[wicked violet]

no its for like playing as an animal

[thorn vector]

hey folks! Was reading this doc and got to the part labeled Using Custom Movement Modes (https://docs.unrealengine.com/5.3/en-US/understanding-networked-movement-in-the-character-movement-component-for-unreal-engine/)

people that have custom movement modes: do you normally implement this as an implementation of the UpdateCustomMovement event like in the doc, or do you extend the CMC (or whichever movementcomponent class you're using as your base) into a custom subclass and implement in C++?

use case context:
||I'm making a base class for a mountable actor--it switches to a custom movement mode on mount. I want the base behavior during the custom movement mode to just be the default CMC walking movementmode behavior. I was hoping to be able to grab the CMC and just call a Walk function or something like that from the BP, but that doesn't seem to turn up any leads||

[neon gull]

can i have something of a predefined list with values that are BP classes?

something like an object library but for classes, not objects

[surreal peak]

@neon gull an Array of Classes can be made, yea

[neon gull]

in form of an asset liek this?

[surreal peak]

Never used that. I think it's better if you'd explain what you want to achieve

[neon gull]

i have a custom level editor, and im creating the interface widget which will have these 4 widgets that will have a custom actor class property, which is going to be used to spawn the actors into the level. so i would load the first 4 classes into these widgets, and if the user will go to the next page im going to replace the custom actor class property with a new one from the list.

kinda

in short terms i need to have list of my actor classes since there are a lot of them, and i will iterate that list to fill the widgets that when pressed will spawn an actor with the specified actor class

[low venture]

Yes, a TArray of the actor's classes. Maybe you should think about giving them all the same base class, then you only need one TArray.

And then you can spawn them with SpawnActorFromClass-node.

[surreal peak]

Yop and array in some accessible class, like GameMode, should work just fine for this

If you want it asset driven you can make a DataTable fwiw

[crude dew]

This is probably quite a simple question I have a widget with a Text Component inside it which I want to add a variable to set the size of the text dynamically and assign the text dynamically also, as you can see I cant put a Float Variable into the Set Size struct part of the SlateFont, Is this possible ?

[low venture]

@crude dew You should be able to select the variables you want to change when you click the Set-members-in-node.

[pallid nest]

Quick one please, I have a bool in my bp character (checking if the tutorial has been passed) .
I suspect I will need to access to it regularly to check if something happened and keep the progression. I believe the most optimal way to do this is with an instance is this correct (perhaps a functin or casting event, what do you think please?) I ask this as I am really bad with instances

[dapper zephyr]

hey folks 🙂 Anyone know what could be causing this error that gets repeated, simply based on how many ticks have passed? Because the crazy part is, that what i want does work, even tho i get the errors. What i want to make, is a music player, that increases volume based on mic input (i got noisy birds 😉 ). and it works, but i do get these errors

[dapper zephyr]

nvm i fixed it using a isvalid node 😄

[thin panther]

Don't use a delay on tick

Use a timer

[solid needle]

hello, i am making a UI for character faces and want to get the live 2d capture on a widget, I am confused on how to do this

[frosty heron]

You should be able to find tutorial on youtube for this.

You will need to create material for the render target. Might also have to invert the texture afaik. You can then use that material that takes in the render target and assign that to your widget

[solid needle]

i tried search but its an NPC with mutliple cameras and i need the isntance of THAT camera

i cant seem to find a way to get the display of 2D capture

i got all the stuff, just how do i get that widget iamge to get reference to whatever display is capturing it

[tough kiln]

I assume you're trying to access this variable from another class? If so, interfaces would be the way forward.

[graceful forum]

Is it possible to get the size of the texture from this material node or am I forced to give that as scalar parameters?

[pallid nest]

yes correct, many thanks

would actually I replied too early, would the level blueprint be considered as a class?

[compact vapor]

is the begin play node of an actor BP called when the actor is spawned at runtime?

[pallid nest]

unless another bp deactivates the actor... I think so (but I am a noob so I might be wrong)

[tough kiln]

In theory everything is an instance of a class, but you should treat the level blueprint as something that is only able to interact with itself and whatever begins life in the level. You need to get balls deep in c++ to have any chance of accessing levels, and even if you do, it's bloody chaos.

[dapper zephyr]

how can one obtain the average of a float, coming from an event tick?

in this case the input from 1 to 2 from a microphone (audio capture)

because i want to make it so it fades out NOT fade in, but this useless parameter only lets me fade in AND fade out

and i know there is a sound mix class which has parameters specifically for fading out, but it seems so far, like i cannot utilize the sound mix blueprint in my scenario

[compact locust]

u could just start camera fade with no alpha either way, it fades audio

[dapper zephyr]

wait whut?

i dont see what this has to do with cameras

i am not making a game just to clarify i dont even have a camera in my scene

i am trying to make an application that does fake noise cancellation. it increases/decreases music volume based on mic input

and its working already, but i cant make it fade out slow because no parameter for it

this is what i got

and it works together with this

mic input on the left

[dapper zephyr]

ignore that the setting of the volume wasn't set here btw ^^

[full badger]

Am I accessing other blueprint variables wrong or something? I'm trying to build a "counter" system for when you overlap a trigger volume.

I have the totalCount variable stored on the player character asset and am trying to access it from the level blueprint to detect when you overlap the trigger. It fires the sound fine and displays the screen message that I want, but it does not add to the totalCount. I then get all these errors.

I've followed probably five different tutorials on YouTube and follow them exactly and it just does not work.

Is this setup wrong somewhere?

[thin panther]

Yes. Nowhere do you show ever setting that variable

It's of the correct type, but you haven't put anything in it

Your player character car is redundant though, you have a nice casted reference on the output of the cast

[compact locust]

dont cast the player character, get the other actor, which is ur character that overlapped whatever that thing is, then if class equals the class of ur character, cast that character to ur BP class and get ur stuff, that way only ur player character can trigger that thing. also yea the varibale stuff ^^^'

[thin panther]

Why not use that, rather than a var you've never set

[dapper zephyr]

completely unnecessary in what i am trying to accomplish + didn't answer my question

[thin panther]

Sure, go ahead and keep doing it wrong

[dapper zephyr]

i am out here making my own fading out system because unreal engine doesn't provide it

[thin panther]

I won't stop you

[dapper zephyr]

well tyvm for not stopping me 😄

[full badger]

wait what? I thought this is what that was. Or did I get mixed up

[thin panther]

That isn't setting the reference of the player character

That's setting an int called "Total Secret Areas Found"

[full badger]

So what is it that I have to set? I can probably figure it out if you can point me in the right direction

[trim matrix]

so back to trying to sort out the stupid issue with simply my enemy throwing the player

[thin panther]

It literally does

[thin panther]

The player reference. Though that variable doesn't matter because your cast outputs a nice reference to the player already

[dapper zephyr]

^^ not with what i am trying to achieve

[thin panther]

Then just use the "Fade out" node

[dapper zephyr]

that is to litteraly stop a song/sound file

you do know that right?

again. context is a big thing, so i suggest you read what i said i am making/trying to make

[thin panther]

All sounds are a "sound file".
I don't see any reason you can't adapt this to use the proper method.

And that's still avoiding the fact a delay on tick isn't doing what you think it is 🤷

[full badger]

I must be super confused then cause nothing seems to work lol

[thin panther]

Ah I do see what you're trying to do with the sound, yeah.

You still don't want the delay on tick though

[dapper zephyr]

i am pretty far now but i got one issue atm

in this part because of the setting of the tick amount (3 seconds), it INSTANTLY grabs what the input amount is, so it never goes much higher then .6 input

so i would like it to check for like .5 seconds or maybe a second after going through that true statement in that branch

the time til check is a float variable i made for the delay so i can adjust it

it would be even better if i can somehow get an "average" of the mic input float. how would one go about that?

[thin panther]

You'd need to define the period of time to get an average

Then you would simply just store each result until that time has passed, where you take an average

[crude dew]

Thanks for the reply, Im not sure what you mean sorry as you see from the image i cant seem to "set" font size.

[dapper zephyr]

ia hve no idea how to do either of those things in a blueprint tbh

i found this but idk if its useful for me

okay i got this far now lol

[trim matrix]

Anyone help here at all

I'm lost for words i've defo done something wrong cause I've noticed the following

When it does this bit the player seems to go off into middle of no where

Then when it does this but the player actually returns to location of where it was when launched and is actually launched

[broken gazelle]

Is there a way to swap the root component on an actor after I've already set one?

[untold rain]

i tried making the pitch or y axis camera movement but it isnt moving properly , do i need to enable or disable something on my spring or camera component

[main crest]

Anyone know how to use a variable to create desired modifers for an "Input Action"? I don't want to get it from the exsisting IA I just want to create a standalone variable

[faint pasture]

At design time or run time?

[faint pasture]

Print control rotation on tick in your pawn or playercontroller, confirm that it's getting changed. If it is, then it's the fault of whatever is USING control rotation

[faint pasture]

Timeline or FInterpToConstant

Timeline if it's meant to be something that gets stopped and started and you want it to fade in/out over a set time

[faint pasture]

FInterpTo if you want some smoothed value to "chase" a target value smoothly, that's more for it you want to do something where the sound value changes all the time.

[faint pasture]

Where is your yaw coming from? Is your pitch input in the same class as your yaw?

[dapper zephyr]

tysm! i am not sure how to setup the Finterp correctly though. if its not too much to ask for, it would be awesome if you could give an example based on these screenshots/my setup currently:

Note: the "how loud" float, is the mic input with a min. value of 0 and a max. value of 2

[untold rain]

yep pitch input is in the same class

[faint pasture]

Tick -> calculate target (I'm guessing your mic level) -> FInterpTo or FInterpToConstant ActualValue towards Target

You trying to do ducking/gating?

or smooth out the mic level over time for some gameplay purposes like Lethal Company?

[dapper zephyr]

i am making pretty much a fake noise cancelling application. it has music inside the project, and based on mic input (my birds noise 🤣 ), music goes either lower or higher

[full badger]

I figured it out btw. I ended up starting the system from scratch and realized I was not fully referencing the PC in the widget I had. I also turned the trigger into an actor blueprint and now I can use just one actor over and over instead of having to make multiple!

[faint pasture]

yeah so ducking

[dapper zephyr]

and i want it to go up fast, but i want it to go lower, slower if thatm akes sense

but i figured maybe having an avg of the float might be even better

[faint pasture]

that'll be tougher but doable

[dapper zephyr]

but maybe i am wrong 😅

[faint pasture]

yeah I'd start with an FInterpToConstant

[dapper zephyr]

what did you mean by calculate target ?

i am assuming that current should be connected to the mic input correct? but i have no idea what to put into the target

[faint pasture]

Target is your How Loud

Current is your sound level, return value becomes new sound level

you can just get delta time, you don't need to drag off the tick function, helps make things a bit cleaner

[dapper zephyr]

i dont have anything in current yet. so so far it isnt working correctly yet

[dapper zephyr]

thx!

[faint pasture]

well yeah, feed current volume in

[untold rain]

@faint pasture am dumb i forgot to set the key value on the mapping context

[dapper zephyr]

i feel super dumb rn but i have no idea where to obtain my "current volume" from

[untold rain]

working after that

[faint pasture]

off the audio component

[dapper zephyr]

urghhh i am such a noob

unless its the multiplier

[compact vapor]

this code is in the level BP and keeps throwing an error

any idea why it cant find the players location?

[dapper zephyr]

nope thats definitely not it 😦

[faint pasture]

probably volume multiplier

whatever adjust volume is actually adjusting

[dapper zephyr]

nope still isnt averaging anything

even with 15 interp speed

[faint pasture]

print your target and interp output

[stone thistle]

Hi, who can help with ALS? How to disable Mantle everywhere except those in the tag, otherwise it creeps in everywhere.

[dapper zephyr]

i am not sure how cuz they are inputs

the input is just the mic volume

[faint pasture]

just add 2 print strings and drag them into it

[faint pasture]

drag whatever's feeding target

your how loud or whatever

[dapper zephyr]

i already have

and its not averaging anything yet

or smoothing whatever you wanna call it 😄

yea.. volume multiplier is NOT it. that one is constantly on 1.0 and not functioning

[faint pasture]

Yeah you might wanna just do this smoothing inside whatever is outputting How Loud and then just use it directly

Adjust Volume is already doing some smoothing too btw

[dapper zephyr]

maybe i should add it into my mainbp over here

[broken gazelle]

Design time

[faint pasture]

yeah just feed the map range into the target and put How Loud into the current

[faint pasture]

just drag and drop

[dapper zephyr]

hmm.. it still goes instantly back to 0.1 with no mic input

i think i did exactly as you said

just put a print string directly here aswell and same issue. it goes instant to .1 and max with 0 noise to max noise

[dapper zephyr]

wait whut! so i dont need a second float for the smoothed value at all? 😮

now its not doing anything and just saying 0.0 -.-'

corrected screenshot

ooo cuz i am silly here we go it works tysm again! 😄

[untold rain]

Dont why but my mouse x and y movement feels like added when moving in one direction!
dont know how i can explain, its like when i move relative to y , x rotation is also getting added

[tardy totem]

Hello. What's the difference between "set skinned asset and update" and "set skeletal mesh" nodes? Well, except "Reinit pose" pin.

[dawn gazelle]

One takes a skeletal mesh component reference, the other takes a skinned mesh component, but a skeletal mesh component inherits from skinned mesh component, so it could be used for either. In C++ under the hood, they both call SetSkeletalMesh() and yeah, just the Reinit Pose option on the one.

[dim thorn]

Hi guys... i was having trouble with forward and backward movement...my character moves left and right very good also forward but when i press "S" it does not move 😦 , how can i fix this can anyone help me with it?

[tardy totem]

Got it, thank you.

[lunar sleet]

need some help for a change. It seems levels default to Y axis pointing right but when you create a char, its inherent arrow component (and therefore its fwd vector) face X, so it ends up pointing the wrong way when spawned. how do I get around this, I can't re-order the components' hierarchy because it's built that way by Epic

[versed sun]

I just rotate my mesh, and adjust my IA_controls

and spawn it in rotated the way i want

[lunar sleet]

yeah, I was rotating it manually when placing, guess I'll just apply the rotation when spawning too. It seems Epic decided to make chars face Y when everything else faces X for some reason lol

[versed sun]

yah , even the example Manny mesh is rotated

i believe

[lunar sleet]

yeah. prly cause base char class is written that way

[versed sun]

thats what coding is, Im going to adjust MY code instead of fixing the problem

Pretty sure that's how Indexes start at 0, someone goofed and everyone goes with it

[spark steppe]

i don't think so

indexes are kind of memory offsets, the first element has an offset of 0

[versed sun]

oh, i dont doubt it

[lunar sleet]

sexy

that makes more sense now

[brazen stirrup]

anyone know why I cant controll my character after I press the start key ?

[dim thorn]

😭

[dapper zephyr]

next issue xD how do i make sure that the next song starts playing from my random song list after the first song is done?

as of rn it decided to not go to the next song

nvm got it 😄

[true valve]

Is there a way to add the physics constraint actor in a blueprint actor?

[faint pasture]

physics constraint component

Physics Constraint Actor is just a vehicle for the Physics Constraint Component which is just a vehicle for a constraint in the physics scene

[true valve]

You can't attach actors in the component

[faint pasture]

your world directions are sus

[faint pasture]

can attach the components within them

root component or whichever component you want

[true valve]

I have a player character blueprint and a cart actor blueprint

I want to attach the cart actor to my player

[faint pasture]

I would use a grabber component anyway but that's doable

the physics constraint actor probably just chooses the root component or the first simulating component it finds on the target actor

constraining an actor isn't really a thing

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Physics/Components/PhysicsHandle/

Use this tho

it uses a constraint under the hood I'm pretty sure. You can do it either way but this might be simpler

[true valve]

So in my player lueprint, i added a physics constraint and a childactor.

Childactor contains the BP_Cart

WOult that work

[true valve]

I'm using BP only

[novel bay]

hey all, silly question, how do you make an empty group or transform in a blueprint? I want to make a null as the root.

[faint pasture]

sec

[spark steppe]

use a scene component

[novel bay]

thanks

🙂

[faint pasture]

@true valve

make sure you are constraining the capsule and the component thats simulating physics

[lofty rapids]

what does your mapping look like ?

[faint pasture]

print those raw values first

make sure they're correct

also your world direction is sus

[dim thorn]

guys i fixed it... i just added backward anim for the S

also thank you for your suggestion I'll try that way too

[brazen stirrup]

solved this, but can someone tell me if this is a optimal way of doing start menu funcionality?

[faint pasture]

no it's not

[brazen stirrup]

how so?

[faint pasture]

Brittle, it'll fail if there's more than one B Als Player whatever in the world

what is that, the selected pawn?

[brazen stirrup]

yeah, but I detached the pawn before so I dont interact with it when the hud is available

not hud menu

[faint pasture]

I'm guessing you select which pawn class you're gonna drive around, and then possess it on start right?

[brazen stirrup]

yeah

I tried using the player character but since i detached it , it was empty

[faint pasture]

Do the pawns need to be spawned into the world when the select button is hit or just when Start is hit?

[brazen stirrup]

the pawns are already spawned, only possesed when select is hit

I think what ill do is have a blank level, then load the level instead of doing what I am now lol

[faint pasture]

Are there different pawns you can control or just the 1 class?

[brazen stirrup]

btw the pawn is the main character

just the 1

[faint pasture]

oh so no class select, just press button -> start game

[brazen stirrup]

yeah exactly

[faint pasture]

yeah start game opening a level or calling RestartPlayer would be best

[brazen stirrup]

yup

[faint pasture]

then you'd have 1 spectator pawn for the start menu etc and 1 for gameplay

[broken gazelle]

Can I not do line trace by objects in an actor's begin play? I'm doing a line trace down to static world (landscape) with ignore self and I get different z points for different actors

[true valve]

So your selected constraint is primitive component. My selected object would be the actor.

[faint pasture]

thats not a thing

[brazen stirrup]

what about puase menu though? I would imagine I have to disable controls on the main character somehow

[faint pasture]

you need to figure out WHICH primitive within the actor you want to constrain

the constraint actor probably just does that in the C++ side

[broken gazelle]

The reason I'm doing this is to set the actor's location to that point. When trying to spawn this actor using Spawn Actor and providing a location, the spawned actor has actually a different location than what was provided

Deriving from Character and then reparenting to Actor messed everything everything up?

[true valve]

That was it. Huge help. Thanks.

[broken gazelle]

Why is a Spawn Actor isn't spawning in the provided transform location? It is set to ignore collision and just spawn

[faint pasture]

If it's for player pawn spawning why not just use the typical gamemode system

[broken gazelle]

It isn't a pawn

Just an actor

[faint pasture]

ya show code and also draw debug the position

[broken gazelle]

Kind hard to do

As a general question

If I spawn an actor at a location using Spawn Actor. The actor should have that location set right? (Given I set ignore collision spawn)

[faint pasture]

sure, on spawn

if it has some code to adjust its position after the fact then it might move instantly

what is the actor?

Like, a Character won't stay inside a wall if spawned in there, it'll depenetrate on first movement update

[broken gazelle]

Just an actor with a mesh

Deriving from Actor

[faint pasture]

yeah you need to debug draw something at the location and make sure the location is what you think it is

[broken gazelle]

Yeah I printed it

I have it 100 as z, and it shows -something at begin play

It all started happening once I reparented from Character back to Actor

And I have some subclass actors from the same actor, with different meshes, and their actor z is random at begin play

Very fun stuff

[faint pasture]

yeah mighta bricked something. Test with a fresh actor with no reparenting shenanigans but otherwise the same mesh etc

[broken gazelle]

I will have to hack it

God damnit it

I fixed it by having a box collision as the root

🤷‍♂️

[edgy eagle]

hello, i need to create a console command
but with console command i need to call a function from a player pawn blueprint class
how i can do this?
only events?

[faint pasture]

you need C++ for an actual console command

[edgy eagle]

yea but how i can call BP function from c++
the only thing i googled is UObject::CallFunctionByNameWithArguments
so i need to create some helper c++ class and make console command with this thingy?

[faint pasture]

The easy way would be to make it not a BP function

what function is it?

[edgy eagle]

this function in BP pawn class that adds items into inventory

[faint pasture]

If the project is mostly BP it'd be easiest to just make a testing UI widget or something

[edgy eagle]

maybe i need to make pawn a c++ class
put this function in this c++ class
mark it as virtual
derive pawn from this class
implement anything else
override function

this looks like a lot of questionable work for simple task of adding a console command

[faint pasture]

for a Real™️ project you usually have your base classes in C++ and all the core functionality there

for BP I'd do something hacky like make a UI widget for it or something

[edgy eagle]

well, the main reason why i started to make almost everything in BP - it's just more convenient to search needed function without opening docs every 5s
for the person who not know ue5 well it's super convenient

and also it compiles in 0.5s instead of 10s

i will make c++ base in my next project definitely

[faint pasture]

Yeah I'd do something hacky here.

I've done all sorts of stuff like using a widget + pawn as a tilemap level editor lol

instead of making a custom editor mode because fuck that

[edgy eagle]

yea, i think ui widget is a best way to do this stuff without rewriting classes
ok thanks

[kind estuary]

Is there any difference between doing these 2 different ways?

seems the second one is more performant, or its the same thing?

[zealous moth]

barely, at that point, use tags

"does actor have tag"

[sonic crest]

The first one you're checking with the object that's present in your world.
You're getting the object in the world then casting it to your FloorTile as the object of the incoming object, if the incoming object is not a part of the floor tile, it'll check again with the other cast
The second is you're getting the class of that object. Comparing the incoming object, get the class and check if it's the same class

[faint pasture]

What are you ACTUALLY trying to check for?

[trim matrix]

this is an easy question I think, I just can't think best way to do it but whats my best option for like an interaction progress thing

so like if hold time is 3 I have a progress bar of some sort move up percent closer to 100 i.e to you holding key for 3 seconds

currently way I'm doing it we isn't working haha

[kind estuary]

trying to see if its the same class

and i know now casting isnt bad

but i used to think casting was the worst thing in performance

so in my code sometimes i have this class check instead of castin

[faint pasture]

Why are you checking 2 classes?

what game mechanic are you trying to do

[bleak mica]

ok, i can not seem to understand async, I have tried numerous combination of node setups to no avail, i have this node setup on a loop to spawn different parts. when connected to the async it only spawns 1 actor, but when i bypass the async it spawns all of them. can anyone explain whats going on.

thanks

[trim matrix]

So i have this Get IA_Interact but it doesn't return to me the time the key is being held down for ?

any ideas as at the moment I'm trying to do it where a little progress thing goes up longer you hold key down and when it reach say 3 seconds the time you need to hold key down for the progress thing will have reached the max level

currently the Get_IA thing is return 0.0 nothing higher

[kind estuary]

cause if its not one then it might be the other.

[willow cedar]

How would I take 2 Vectors and Find out if one is to the Left or Right side of the other. Just talking X and Y here, no Z.

I need a Positive number to be one side, and a Negative to be the other.

[true valve]

You know to replicate Break Constraint

[remote silo]

So im new at this, and cant seem to wrap my head around why my character just floats in the air now, i messed somthing up.

Its pointing at "IsFalling?" when i hit play.
i have been trying to figure this out for hours.
i looked at the other questions on Accessed none in here, but i still dont get it, or why its just not working

[lofty rapids]

is your character on the ground ? or is it floating ?

[remote silo]

i moved it into the air to see if it would fall at all, and its just stuck

[lofty rapids]

are you using the camera thats on the player ? does it work or is the camera floating ?

[remote silo]

camara works, i can look around

[lofty rapids]

it's a character class and set as your pawn ?

[remote silo]

i dont know, im dumB

im realy new at all this, iv been working trying to learn blueprints, its all barly starting to click togeather, im still not sure what im doing though

[lofty rapids]

well your character should drop onto the ground

[lofty rapids]

what does it say for gravity scale in your character movement ?

[remote silo]

1.0

[lofty rapids]

why is it grayed out ?

[remote silo]

im guessing its not supposed to be? lol

[lofty rapids]

thats your character movement on the player ?

hmm

did you do anything in c++ ?

[remote silo]

nope

im 100% willing to stream this

[lofty rapids]

what do your components look like ?

i know a little bit but i can only help so much

[remote silo]

well, at this point my brain is fryed. what are the components?
and all good, any help is fine.

[lofty rapids]

where you clicked on the character movement

up at the left side

how you got those details

in your character bp

then in those details of the character movement it should of been able to be set but i don't know what that means it's grayed out

are you using some sort of custom movement thing ?

[remote silo]

this is in my AnimBP

animatiion blueprint of my character

[lofty rapids]

i'm talking about your actual character

[remote silo]

in my character i dont have a components, this is all i have

at any point just let me know im un saveable, and ill re do all this lol.
tutorials only took like 4 hours to do, iv been trying to fix this for like 16 hours.

im wondering if i inharited character movment from the BP_Firstperson_character, because i dont have character movement in BP_Lola which has been working untill now

[small wedge]

(for context, I'm making a text-to-speech vocalizer)

I want to take a single string like this:
{ae}iu

And separate it into three distinct strings:
{ae}, i, and u. This will be sent to a string-to-vector map in order to send it to my metasounds, one at a time.

How can I convert that single string into those three pieces of info? Letters that do not have curly brackets will be read out one letter at a time, but the ones with curly brackets are all one single phoneme.

[lofty rapids]

the components at the top left, scroll down there should be a character movement one

[remote silo]

ah yes its there, but when i click on it there are no details

[lofty rapids]

i squished it to fit into one image

[remote silo]

its beautiful

[small wedge]

oh wow, yeah that looks like it'd do the trick

thank you!

[frosty heron]

You need to set the 2d capture scene to use that render target. You will also need to invert the render target in the material editor

I've done it multiple times, it's a straight forward process. Make sure you play in the game too for the scene capture to update

[lofty rapids]

thats probably not a good thing you got no details

[lofty rapids]

if you click on the mesh in the components do you see details ?

[remote silo]

Nothin

[lofty rapids]

what version of unreal ?

[remote silo]

5.3.2

[lofty rapids]

if you click on self, nothing ?

[lofty rapids]

ok

see where you have search character

?

[remote silo]

yes

[lofty rapids]

take that out

set it back to none

because that search carries over

shouldn't matter though

[remote silo]

Still nothing in Character Movement, or mesh

[lofty rapids]

i think the problem is a bug because you should have details

you must have had them at some point

[remote silo]

you would think, because i was able to move

[lofty rapids]

hmm, idk enough to know why that's happening

but i have seen similar on this discord where it was a bug

[remote silo]

all good, ill try and recreate all of it, and see if i can figure out new stuff.
100% appreciate your help :D, i learned some stuff

[paper smelt]

Why is their no add button?

[surreal peak]

Did you really select DataTable?

There is also this composite stuff iirc

@paper smelt

[paper smelt]

💀 I somehow did the other one didnt even know a composite one was their lol

[kind estuary]

why use pawn sensing instead of just an extra collision that overlaps?
isnt pawn sensing a kind of a overlap collision with extra steps?

[surreal peak]

If an extra collision is enough for your game then do that

[kind estuary]

thank you. have a great xmas 🐺 🎄 🎁

[violet matrix]

I wonder if its possible to spawn maps as actors on a good distance far away from the main map. I think of having over 100 same maps, but I wonder can you make the map not rendered except when they are inside the map? Is there an optimized way of doing this? Because having 100+ maps active will overload the gpu

[hushed ferry]

why do you want that

[faint pasture]

What are you actually trying to do?

hey guys! im making a cooldown and using the Radial Slider in the Widgets Blueprint so that the slider moves around and will go from 0 to 360 during the duration of my cooldown timer, is there a way to move the slider's end angle at runtime? I'm doing this rn

when i use breakpoints on my "Set Slider Handle End Angle", it seems like that value is changing but it doesn't reflect in the UI

[frosty heron]

Your return value is always 0

[sullen hinge]

ah got it

thx

but rn it then goes from 0 to 360

[frosty heron]

I'm not sure what u are trying to do. In any case , print string to debug and figure out if the value isn't what u intend

[sullen hinge]

ok

[frosty heron]

I mean Ur clamping from 0 to 360, if that's not the intention, then you need to explain what you are trying to do

[sullen hinge]

basically what im trying to do is have a radial slider that goes from 0 to 360 based on my cooldown timer countdown. So if my countdown is 10 seconds, the end angle should go from 0 to 360 during those 10 seconds with about 36 degrees per second.

[frosty heron]

Macro only available in the class it's declared in. If you want to use it across multiple actors, use macro library instead making it inside that one specific actor

[sullen hinge]

ok i think i have an idea

i have to normalize it

[frosty heron]

Map range clamped

In value is 0 to Max cool down. Out value is 0 to 360

Value will be current cool down

[dapper zephyr]

hmm issue currently guys. it only does the top row, and never does the bottom row (when the "bruce springsteen playlist" is playing)

it does obtain the mic input volume correctly tho according to the print string

[last abyss]

right click the beginplay node

[frosty heron]

@dapper zephyr you shouldn't need to use tick, delay or get all actor of class just to set volume. Create a function to change the volume instead

[dapper zephyr]

i do. its not a videogame. it needs to litteraly check non stop my mic input

unless a function also acts as a tick idk

another question btw! is it possible to control windows volume mixer, through ue5? i see there is a plugin for it but its 18 euros, and i would prefer making it myself IF this is possible purely through blueprints

[stone thistle]

How to make "Can Character Step Up On" for components? As far as I understand, this only works with pawns.

[frosty heron]

Blueprint is very limited, afaik there is nothing for hardware stuff

[dapper zephyr]

thats a shame. thx

i will just keep importing more songs into unreal then lol!

altough the max filesize for .wav is 2 GB which is also annoying

[sullen hinge]

Can't find any relevant info rn on the internet but does anyone know if the Radial Slider's "Get Slider Value" binding update every frame? I'm currently trying change the value of the slider based on normalized values, but when I breakpoint it, it seems to not be changing.

What I did here was get the cooldown that goes from 4 to 0. and based on that i divide 360/4 to set the interval in which how many degrees should be covered per second.
Then I add that to the current Slider Handle End Angle.
Next I normalize it to get a value between 0 and 1 that is of the same proportion
And finally set it.
But it doesn't seem like the normalize value changes.

[stone thistle]

@trim matrix If you don't mind, can you give me an example?

[dapper zephyr]

how does one set something to invalid?

i need to set one of these to invalid at a certain point

[edgy ingot]

You set the variable to null

[stone thistle]

@trim matrixThanks, I'll try to look it up on YouTube.

[dapper zephyr]

how can one set a audio component to null?

[edgy ingot]

Is it a variable you create? Or a component you add by clicking on the plus button in component tab?

Full screen shoot will paint better picture

[dapper zephyr]

either way i fixed my issue by enabling auto destroy, on the creation of a new sound 2D (playlist), because i disabled that before and that broke the volume adjusting

so it was just silly on my end ^^

i dont mind sharing my current setup either way though if you wanna see it 🙂

only bug left atm is the pause/unpause part, because that isnt going through validation checking yet, so it throws some errors but still works

[small wedge]

Is there any way to simplify this further? My gut feeling tells me that there must be a way to do this without a branch node, and without needing to have those two near-identical append nodes

Basically:
Look at the string map and use the outputted string instead.
But if it's not in the map, then just use the original string.

[remote meteor]

append B will become a select node, true for map find output, false for current ipa, boolean comes from the find node

[small wedge]

Perfect, thank you!

[red berry]

Anyone have any ideas about implementing item variations? I already have items with Data assets, but I need to somehow deal with variations, e.g. color, wear (new, used, old). Would I do an array of potential variations? Should I subclass Data assets?
Some items won't have certain variations, because there's no mesh for them.

[sullen hinge]

got this to work! i ended up moving my normalize calculations into my countdown event on the player, and instead set the value of the slider to a value variable and then in the event tick i would update that variable

[surreal peak]

In theory if they all use the same skeleton, it should work fine. If the anims are messed up when you place multiple then it might be your code.

[small wedge]

I need this map lookup to be case sensitive, but it's not. How can I make this map case sensitive?

[surreal peak]

Pretty sure the default == operator is case-insensitive.

Not sure you can do much about that in BP

[sonic crest]

===

[surreal peak]

That doesn't help if they want the TMap to simply use Find

TMap uses == operator for that. Even in C++ you'd need to create a custom key that wraps the FString and uses the case-sensitive Matches function.

They would need to use an array instead fwiw

[tough kiln]

Yeah all you could do is format string to bring it in line with whatever convention you're using. If you don't have a convention, you should create one. Alternatively, you could cast all map keys to lower case before assigning them and then do the same when doing a key look up.

[spark steppe]

that's pretty much the opposite of case sensitive

best bet might be to check how FString provides its hash, eventually it does stringToLower there?

at least i would expect it to behave similar in C++ and BP

how it is even possible?

[grizzled cave]

my game is in normal speed when i play with one game window open but 2 windows makes the game time slow
i tried different characters, levels, gamemodes

well... is your pc maybe just too slow?

[spark steppe]

sadly this is C++ only!?

//Case-sensitive TMap has no support in Blueprints 😦

[mental trellis]

Make a ustruct with its own hash generator and use that in bps?

[neon gull]

is it possible to get string from class?

[spark steppe]

what string?

from a variable?

the class name?

[neon gull]

yes

the name of it

[spark steppe]

get class name

eventually you have to convert it to Text then

[neon gull]

oh ty

was looking for tostring and getname

[spark steppe]

i'm not sure if it's get class name tho

might be named different (but it exists)

[neon gull]

its get class display name

[remote silo]

I FIGURED IT OUT!

1. In character Blueprint / Class settings
2. Change Parrent class from BP_Character To Actor or anything, and back to your Main BP_Character. now i have Character movement details

all i had to do after was re align my character with the capsule collsion.
one thing extra that i noticed it do, was when i loaded strait into a map with my character it was crashing, but if i loaded with the defualt character i could move and it didnt crash.
If i loaded from the main menu, my character was stuck, but my game didnt crash

[dry sleet]

reparenting can often fix a corrupt blueprint but naturally it's the nuclear option!

when the details panel is empty it's apparently a pretty clear sign your BP has become corrupt

did you by any chance use Live Coding?

[remote silo]

im realy new at this, is that this thing ?

[surreal peak]

Live Coding is used with C++

[dry sleet]

live coding is when you reload C++ without closing the unreal editor

[surreal peak]

If you aren't using C++, then that's irrelevant for you

[remote silo]

oh, im going to try an stick with blueprints

[surreal peak]

That's actually hot reloading. Live Coding is the better version. Can still lead to problems but by far not as shitty

[dry sleet]

Both can be described that way

But yes hot reload is worse for corruption

[surreal peak]

I usually have to trigger live Coding via key binding.

[spark steppe]

but both serve the purpose of recompile while the editor runs

the thing in the screenshot is for the blueprint/game debugger

[pastel skiff]

i got a wierd problem
there is an elevator and door, the door opens when i click E, all fine, when i click E the elevator moves, all fine agin, BUT when i use the elevator and try to open the door after, it moves the elevator? i have no idea what is wrong, plese help

[coarse grove]

In your function "Interact" you are not using the input interactor, so you might not setting properly with who you are interacting, and your return is always false since there is a return to false and there is no variable on it.

[pastel skiff]

thnaks i will try to chnage it

[pastel skiff]

OH GOD IT WORKED i was trying to fix this crap for a long time thnaks

[steep lily]

So would it be wrong to use cast to and get all actor of class in the same blue print or task. Would it cause it to slow or else?

[snow gazelle]

I made a grabbing mechanics in a game following a tutorial and adding some modifications of mine. And I need help with two things: fixing a bug where the player flies when standing on the grabbed object, and making the object's mass affect how hard it is to lift, push, or pull it. Can someone help me make these changes?

[trim matrix]

I could be wrong but live coding is fine

It's hot reload that can mess-up

[dry sleet]

It can cause issues still.

[trim matrix]

Never had issues tbf only when hot reload here and there

[dry sleet]

If you edit header files and create new classes which you then use to create blueprints or data assets they are ephemeral and will cause data loss upon restarting the editor.

[trim matrix]

I don't think I've ever use live coding

[dry sleet]

Live Coding with Reinstancing disabled is apparently quite safe but still, never to be used when editing header files.

It's very nice when iterating on functions, so no need to shun it

[dry sleet]

It fully depends on the use case. Get All Actors by Class is relatively slow, so you don't want to do it every frame.

Doing it once (perhaps in Begin Play) and storing the results is fine.

[edgy eagle]

are there some quick tip to translate max speed into max rpm i need to set?
in ChaosWheeledVehicleMovementComponent

[dry sleet]

However I maintain that it's rare to need that node if you have your architecture set up correct. You can often avoid it. People may disagree with that, though.

[dry sleet]

Casting in blueprint is mostly fine. In C++ it's very fine. The reason you might want to avoid it in blueprint is that it causes a dependency: the cast-to class will automatically be loaded when the class doing the casting is loaded, increasing memory usage and load times.

[rose kettle]

Does anyone know how to solve this problem?

[dry sleet]

You can mitigate the dependencies using interfaces and soft references.

[dry sleet]

Do you have visual studio installed?

I see you don't have a solution file.

[rose kettle]

yeah

[dry sleet]

If you have VS you need to right click the .uproject file and select "Generate Visual Studio project files"

That will give you a visual studio solution in the same folder.

[rose kettle]

I don see it

[dry sleet]

Win11.

Show more options?

[rose kettle]

Oh yeah

did it and it said need to create a cpp class first

[dry sleet]

Aha.

Yes, you can do that from within the Unreal project...

Which I guess spud prevents you from opening.

You could always remove the plugin and the dependency temporarily until you have your project set up for c++.

https://docs.unrealengine.com/5.3/en-US/unreal-engine-cpp-quick-start/

this has some pointers

[rose kettle]

created a new cpp class, tried again, then it said to install .net

[dry sleet]

yes, you need that

it should have a link

[rose kettle]

ok sec

Thanks

[dry sleet]

Did it work?

[rose kettle]

Still downloading

[dry sleet]

gotcha

[rose kettle]

Its just that I have a new pc so I forgot all the stuff I needed to install 😆

[dry sleet]

well I'm gonna go watch Lord of the Rings per Christmas tradition but ping me if you still have problems later on and I can take a look!

someone in #cpp can probably give you a hint otherwise!

[lunar sleet]

you'll need VS2022 or other IDE

[rose kettle]

Based lotr enjoyer👍

[dry sleet]

of course!!

[rose kettle]

😢

Now even without the plugin the project wont load

WHAT HAVE I DONE

[remote meteor]

click yes maybe?

and also

[rose kettle]

Tried, same error

[remote meteor]

check this 3 in visual studio installer

also if you look carefully, it asks for .NET Framework, not .NET SDK

so maybe just install .NET Framework 4.8

[rose kettle]

The only one that was unchecked was the .net one

Is there really a difference? I am confused

[remote meteor]

they are different things, .NET Framework vs .NET SDK

lol

[rose kettle]

😔

[hearty jackal]

Those 3 must be checked and installed

[rose kettle]

Hopefully this is the thing

[untold rain]

my mesh details panel is empty

[dry sleet]

It might be blueprint corruption. You can mitigate it by changing the BP parent to Actor and back, but be aware that your overridden settings in all components of the blueprint will be lost if you do.

Make a backup first. If you have source control, make a commit.

[hearty jackal]

What could cause blueprint corruption?

[mental trellis]

Hot reload. Live coding. Bad luck?

[stiff swift]

If my BP corrupted I'd be sooo sadge

But if it's just the details and code is still there should be able to re texture and mesh then save odd though indead

[mental trellis]

Did someone say #source-control ?!

[lean hound]

I have a widget attached onto an enemy to act as a health bar but the issue is the canvas panel acts as part of the hitbox, is there any way to exclude the widget from being part of the hitbox

[remote meteor]

turn off the collisions at the UWidgetComponent

[lean hound]

where would I find the UWIdgetComponent

[mental trellis]

It's the thing the in your blueprint that you set your widget on.

[small wedge]

Why does the "Keys" node have an execute function? Why aren't I able to just get the array without executing it?

[mental trellis]

Because it's not a simple operation.

You're better off using Contains to see if it has the element, not "get keys -> find"

[small wedge]

contains returns a boolean, but I want to get the integer

The integer of the key

Basically, I'm turning the find map node (not pictured) into a case-sensitive one

Here's thie full thing

basically finding a way to use the === node

[mental trellis]

I don't know what you're trying to do, but using the index of a key from a map is not the right way to do it

[small wedge]

I want to use the Find (Map) node, but case sensitive

[mental trellis]

Ah. Yes. They're not case sensitive by default...

So stupid

[small wedge]

Yep, that's the workaround I'm trying to find

Also, I actually go this error now:

Blueprint Runtime Error: "Attempted to access index -1 from array CallFunc_Map_Keys_Keys of length 17!". Node: Set IPA Graph: TIPADecoder Function: TIPADecoder Blueprint: BP_TextToSpeech

[mental trellis]

You can fix it in c++! 😄

[small wedge]

Not sure why or where it's attempting to access index -1

I've never tried combining c++ with blueprints, I'll take a look

[dry sleet]

sometimes with our Houdini Engine setup the level can become corrupt while still allowing you to keep working and committing, and you won't know until you restart the editor next time :(

I've had instances where three consecutive commits were unusable

an awful feeling of uncertainty when even git fails you!!

[lofty rapids]

sounds like your getting a -1 index from that find

you can print string it to see what it looks like

because thats the only index your using

[pulsar vigil]

Hey guys i have a problem with a for each loop that doesn't complete before the initialisation of an anim montage, the for each loop compare distance between the player and multiple scene component (target for motion warping) and it work perfectly but often the second time i use interact and use that for each loop it doesn't finish the comparison and i understand that this is because the play anim montage linked taking the result variable of the for each loop is asynchronous and it doesn't happen the same frame and there is something weird like this i was thinking about adding a delay maybe but i probably dont understand something else, any suggestion ?

[tough kiln]

If it works once, then fails the next time, it may be that you're not resetting your variables such as the distance comparison and closest comp. One easy way to fix this would be to make a function and use local variables.

It's not clear where the montage is being played in relation to the loop comparison.

[round grove]

Can you explain more of this?

[tough kiln]

What would you like explaining?

[round grove]

Resetting the distance and closest component

[tough kiln]

If you have a function CheckDistance(), before you get into any comparison, you initialise variables such as ShortestDistance = 0, ClosestComp= nullptr, then you do your comparison. If you don't do this (and you're using global variables), every time you call the logic, you will be using the values assigned during the last function call. So if your closest distance is 350 and closest comp is SomeBloodyComp, then recall the function, those values will be used in the first iteration of the next comparison.

If you use local variables, the values will be killed when the function ends and reinitialised during the next call.

If you're not sure what local or global variables are, do some research on variable scope.

[pulsar vigil]

My play anim montage is in my bp character meanwhile this for eahcloop is in another actor bp. I go try the function thing but does it change something if i alreaady set the variable that are used to compar distance private ? also yes its what happening it use the prevous result but the thing is the major problem is not that it use the previous stored variable but that it doesnt recalculate and check the closest and set the variable before no ?

the comparison with the for each loop is launched by an event dispacher when i press my interact button and the play anim montage is launched just after the call for the event

[tough kiln]

-1 I believe basically means not found. It's essentially a contains == false. Can I ask why you need case sensitivity? What is the background to why you've chosen this setup? It may be that there's another approach that would avoid all this.

[tough kiln]

I'd suggest that you firstly reconfigure your logic so that the montage playing will always follow the comparison. It sounds like they are interdependent and so there should never be ambiguity about which comes first.

[pulsar vigil]

i totaly agree and thats why i was here asking how to do it

[tough kiln]

Ok so answering that would require more explanation about your current approach and how the logic is being called. Begin from what is triggering your dispatchers.

[pulsar vigil]

my interact input

call an event dispacher that call the function and the montage at the same time

[tough kiln]

So why not call the comparison, then have that comparison function play the montage?

[pulsar vigil]

thats what happening but the play montage play before and i suspect it to be because play montage is an asynchronous node

i call the function before the play montage and use the variable with the closest component to target the motion warping

[tough kiln]

If you call the play montage from the same function as the comparison, it cannot be asyncronous

As long as play montage is called after the loop is completed

[pulsar vigil]

what do u mean same function ?

its not in the same function and i doubt it can be

[tough kiln]

Why do you doubt that

[pulsar vigil]

the function is made in another bp and those thing have to be dissociated

[tough kiln]

Does the actor BP have a reference to the montage playing character?

[pulsar vigil]

he have a reference to the character to get his location and compare it then it procede and set the variable made in the character bp used to target

do u want omore screen shot ?

[tough kiln]

If you have a reference to the character, you can get the mesh and play montage. If the logic is more than just playing a montage, you can make a function/event in the character BP and call that from the actor.

And that function would obviously include playing the montage

[pulsar vigil]

are u sure it would work cause i dont understand why

[tough kiln]

Your confusion is confusing. Try it, test it, and screenshot as much as you can if it doesn't.

[pulsar vigil]

i can't put play montage in a fuction

[small wedge]

I'm converting TIPA (a way to write IPA using LaTeX) into regular IPA. The string a is different than A

I have a string-to-string map that maps these conversions

[pulsar vigil]

that give me the exact same result and only the motion warping work (the first time like before) and its not in a function

[tough kiln]

Ah yes, then you're definitely backed into a corner.

[tough kiln]

You can do anything in a function because everything is a function

[tough kiln]

Then we've ensured that the cause of the problem is not asynchronicity

[pulsar vigil]

alright

[tough kiln]

Have you tried stepping through the loop with the debugger to make sure the results are as you'd expect?

[pulsar vigil]

yeah thats what i was trying i dont know how to do it exactly

[tough kiln]

Right click on the for loop node and set break point

[pulsar vigil]

ah yeah i did that

[tough kiln]

Then when it triggers, you can use the arrows in the top middle of the screen above the graph to step through, after a node has been passed, you can hover the mouse over the variable to see its value

[pulsar vigil]

i did that sorry

[tough kiln]

We can also confirm that this is not the problem as the loop does finish before your montage plays.

[pulsar vigil]

i didnt understand at first but yeah it was working but it was taking the previous variable anyway

[pulsar vigil]

let me retry it

[pulsar vigil]

cause i dont believe this one to be the case, it take the previous variable before finishing the loop that set it

[tough kiln]

Then set that variable to 0 before the for loop

[pulsar vigil]

i tried that and it puted me at the origin of the level

[tough kiln]

The target vector length variable?

Please be as specific and detailed as you can. What variables are not behaving the way you want them to?

[pulsar vigil]

wait i need to test this more and try what u said im lost

[pulsar vigil]

just one question

if i want to make it a function i take the whole for each loop and thats good enought to make it private ?

[tough kiln]

What do you mean private? You mean in its own function?

[pulsar vigil]

or to reset it

yeah u said i need to put in a function to set the variable and reset it everytime its called

last test i did with the breakpoint it does'nt change the final value so im assuming the problem is what u said but it go throught

[tough kiln]

Yeah so what I would do is make a function with the character BP as an input and closest comp as an output, then use the same logic (minus the montage playing) but create and use local variables for your distance float and closest component. Then when the loop is complete, pass the local component variable into your output. I guess you only want to play the montage if you find some kind of close variable so in the interact event, call the function, check if the output component is valid and call the rest of your logic if it is.

[pulsar vigil]

i can tell it work better and it look like it work fine in almost every case but there is one case where it just put my character at the origin point i dont know why and u can't help me with those information but thx it look and work better than before ! and it make sense

[pulsar vigil]

yeah that look to work better but its the same problem than before

it doesn't read the nearest target anymore even sometimes on the first try

[lofty rapids]

whats guardval initial value ?

[pulsar vigil]

10000000000000

im trying iwth a delay it does the same

[tough kiln]

Ok but you're not comparing the distances from one scene component to another. You're just checking if any distance is less than that insane number.

[tough kiln]

You need to set a CheckedDistance value, set it in one loop then compare the next distance to that

[pulsar vigil]

i set guardval if it go throught

oh wait

IT WORK

[proper vigil]

https://youtu.be/oXwj2ahifgY?t=427 Is anyone familiar with this?

[pulsar vigil]

i did a guard val local variable but didnt changed it

now it work guys @tough kiln @lofty rapids

[tough kiln]

Haha

Good stuff

[pulsar vigil]

damn i was wrong all along with my asynchronous thing

[pulsar vigil]

Michael Pattison is in the discord

[proper vigil]

@dark drum Hey! Following along with your dialogue system vids and almost done. However, when pressing E to interact with my character, I see the wrong screen.

This screen.

[pulsar vigil]

u have to convert mkv tomp4

[tough kiln]

Process of elimination amigo. It's the only way to get through these problems.

[proper vigil]

Only thing I think could be the issue is I didn't create a child of the NPC but that seems more like a step to reduce steps if I were to make an additional NPC with this system rather than something that completely changes the system.

[twin perch]

So i require help with Json, Not to sure why this is an issue or how to write this properly.
I am designing a python program to help make level design easier for my game.
the Python program saves a Json File which contains an array of numbers from 0 to number not decided yet which i want Unreal engine to read.

However the blueprint up there always fails.

this is what the json file contains

[[0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 1, 1, 1, 1, 1, 1, 1, 0], [0, 1, 2, 2, 2, 2, 2, 3, 1, 0], [0, 1, 2, 3, 3, 3, 2, 3, 1, 0], [0, 1, 2, 3, 3, 3, 2, 3, 1, 0], [0, 1, 2, 3, 3, 3, 2, 3, 1, 0], [0, 1, 2, 3, 3, 3, 2, 3, 1, 0], [0, 1, 1, 1, 1, 1, 1, 1, 1, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]

the Json File String ... is just the file path to the folder.

does it haft to do something to succeed ? i thought that was just if it succeeded reading it

sorry could you explain that to me in more detail ? @toxic jay i am new to Json.

thank you*

Oh i got it yeah ok cheers for that!

[ruby apex]

How to subscribe to Actor's delegate? I have literally the same delegate inside the component and inside the actor
component event works
actor's event doesn't work

Delegate is:

DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnEncounterAllCharactersDestroyed);

and

UPROPERTY(BlueprintAssignable)
FOnEncounterAllCharactersDestroyed OnEncounterAllCharactersDestroyed;

[frosty heron]

Where did you exactly bind it?

You have not showed that part

In cpp it will be .adddynamic

In blueprint you bind the event

[ruby apex]

I just click "+"

It works for component

[ruby apex]

Is there another way?

[frosty heron]

Bind on begin play maybe.
The one that you said don't work says custom event

I never personally use the + button

[ruby apex]

Oh so Actor events dont do 'bind' automatically

Got it

Sadge

[frosty heron]

Don't know

Is the onwaveallcharacterdestroyed a dynamic multicast delegate too?

[ruby apex]

Yes

They are the same

Logic is the same

[frosty heron]

I see , well I don't know about the + button. Hopefully someone else knows

[regal bane]

My little ship is not moving forward, in the console im printing the xyz values and only the z value is chaning when i press my MoveForward key. Any clue what im doing wrong? using a orthographic camera shooting top down

Because that is your Forward vector?

[kind estuary]

who is the genius person who came up with the idea of blueprints as they are in unreal engine?

probably not a single person but many, right?

Hey gang, does anyone know how to tell the game to NOT play a level sequence when going to a Player Start with a specific Player Tag?

Basically, level opens with a LVSeq (Level Sequence), and I have a few Player Starts with their own tags, and I got the tag/spawning locations down, but every time the player spawns into the map, it plays the opening LVSeq and trying to use a Bool to do that, at least I think that's the best way but I'm out of ideas on how it should be done lol.

(let me know if it doesn't make sense, I'm at the tail end of my day so tiredness is setting in)

[true valve]

Is there anything similar to RandomPointInBoundingBox but for arbitrary points?

[mental trellis]

What do you mean by arbitrary?

Surely you have some range in mind?

[kind estuary]

Is a tile system cheaper and better in performance than actual free moving world system?
It seems it is but tell me if im missing something?
If you do a tile game, then your units dont animate/move constantly, but from tile to tile.

[rose kettle]

Update, I finally got it working, it is truly a christmas miracle! Thank you @dry sleet!

[rose kettle]

Except that it crashes the game every time I try to save 😅

[distant hollow]

How do I define the tile size when applying materials on a dynamic mesh during runtime without having to edit the materials?

[distant hollow]

Insert the codes before the LVSeq

[dry scarab]

is there a way to edit 522 meshes collision all at one time? all the same mesh floor etc

[rose kettle]

Do you mean collision mode or collision shape? If you mean the mode, then you should be able to select them in the world outliner and change the collision preset

My project was/is BP (or started with a BP project at least adding C++)

can't find my character.h file for my game (im assuming because I started out as a BP project it didnt make one...)
Is there any way to not have to migrate my project to a new one [with all the generated C++ files?]
mean this*

[tough kiln]

#materials

[distant hollow]

At runtime, not tweaking materials

[rose kettle]

Theoretically, you could pass the values that you put into your textures uv's to a param collection, that you would then change at runtime

[distant hollow]

I couldn't seem to get any UV info out of the material

[rose kettle]

Put this in the material

then create a material parameter collection

and wherever you want to change the tiling of it you can just do this

[rose kettle]

And this is #materials stuff regardless

[distant hollow]

I can't do this without tinkering with the materials?

Also is the same material supposed to behave differently when applied to static and dynamic meshes?

[remote meteor]

MPC is for global stuff, if its just a specific mateial, use instanced parameter instead

[distant hollow]

I have a list of materials

[remote meteor]

do everyone of them needs the same tiling size?

[distant hollow]

What’s happening now is that when applied to a static mesh the tiling is fine

But when applied to a dynamic mesh it kinda stretches erratically

[edgy ingot]

What ever it is you r trying to do, you best to know what MPC and instanced material is

If u need something global that every single mesh that used that material yield the same result then use MPC otherwise use dynamic material instance

[distant hollow]

So basically I have walls and floors, some made of static meshes and some are dynamic

I can distinguish and handle the two differently by code

So where does that fall in?

[edgy ingot]

Wether to use material parametre collection or instanced material has nothing to do with applying it on static mesh or dynamic mesh

U best just understand what they r and apply accordingly depending on your need
