[prisma stag]

I tried adding a print string after the true branch which is the one I want to execute but it does not show.

[willow breach]

how do i remove only 1 widget

instead of removing all widgets

[fading raptor]

Now you know that something is wrong with that branch, maybe the condition you put in is the wrong one?

[prisma stag]

The condition is the is game paused. So it should work considering the game is set to paused when the widget is shown.

[fading raptor]

Make a print string after where u set the game to paused, and see if it shows up

Maybe the game may show its paused but the bp doesn't register it

[prisma stag]

The print string does show.

[fading raptor]

That means your condition for the branch you made is the wrong one

I dont know your code, but try to find the condition you set where it pauses the game

[prisma stag]

https://blueprintue.com/blueprint/y9uo4bvt/

[willow breach]

why doesnt it do the event?

[fading raptor]

Is the "is game paused" custom made, or does it come with the engine?

[willow breach]

it prints hello

[prisma stag]

Comes with the engine.

[fading raptor]

What determines if the game is paused?

[willow breach]

@fading raptor

[fading raptor]

Im reading ur code give me a sec

[willow breach]

k

[fading raptor]

Its kind of hard to debug when all ur print strings say hello

Rename them then debugg

[prisma stag]

After the true and false branches, I have a set games paused statement. If false, IsGamePaused is set to true and if true, IsGamePaused is set to false.

[willow breach]

ok i changed the first one to 1

[willow breach]

and second to 2

and it switched between 1 and 2

starting with 1

gtg sry :(

[fading raptor]

The problem is in the branch

Try making a custom variable for is game paused and replace it with the engine made is game paused

So instead of the engine is game paused, it would be a boolean you made

And set the boolean wherever you pause the game

[prisma stag]

Alright. Give me a sec.

[fading raptor]

I dont like using engine made things because they don't always align with your code

[prisma stag]

The only reason I use it is because I actually pause the game.

[fading raptor]

Im not familiar with most engine pre-made events/conditions, because they just cause problems tbh, even if u actually pause the game, it still might not register it

[prisma stag]

Oh I got it. I did the branch with the custom variable and it wouldn't work either. Then checked to see if the widget was in focus. I have it set to Set input mode to ui which to me makes sense. However, I saw a video that in order to have the ui and be able to interact with it, you need the ui and game as the input mode and now it works. Thanks for the help though.

[formal wren]

How do I make VInterpTo and other Interp-function FPS unindependant?

*unindependant

mmh this seems to do the trick:

any suggestions?

[sinful sequoia]

@formal wrenWhy not just set SplineInterpSpeed in seconds and multiply it by GetWorldDeltaSeconds?

I'm trying to figure out what asset is used in classe's static mesh (and use same static mesh in another thing) how do I get it from soft reference?

[formal wren]

mmmh yeah, that should also work 😄 I did all my initial tests at 60fps and wanted to maintain the speed I experienced under that framerate 😛

if I just multiply by world delta seconds I think I would have to recalibrate all my speed variables

[sinful sequoia]

@formal wren Other option is probably "SetEventByTimer", not sure about the details

[formal wren]

not possible

i have to use tick. The interp function makes one object follow another objects location

😦

[sinful sequoia]

https://answers.unrealengine.com/questions/711550/how-do-i-make-rinterp-to-framerate-independent.html maybe this will help - seems they suggest same solution

[formal wren]

yeah already found that one

I think my solution works

at least the speeds now seem consistent among different framerates

[wind void]

Is there a way I can make a custom vector that contains Integers instead of floats?
Or if said vector exists?

[sinful sequoia]

@wind voidMake vector?

oh

integers

I can only suggest this

[wind void]

yeah, problem is that I have todo that every time I use it, just wondering if there was a way I could just simplify my code and skip that step.

[sand shore]

You could make a BP struct and you could also make a BP function library. I think you might be able to use FIntPoint or something though

but function libraries exist for that sort of ergonomics

[soft scaffold]

Hi! I tried to make an angle calculator system to calculate the angle between the lines, but something doesn't work correctly. Any idea?

[unkempt moth]

Does anyone know where the best way to learn third person over the shoulder aiming and shooting? I'm not making a shooting game but I need to make a set up like that so I can aim fireballs and arrows where I want.

Tag me please

The fundamentals are kind of explained here. If you want an interactive camera that moves rather then teleports you'll just need to use VinterpTo node, alternatively you can use a timeline to achieve the same effect. I believe VinterpTo is used in Advanced Locomotion System rather then timeline... So it's probably the better method

There are all sorts of settings in the camera that can easily be changed in blueprints as well to achieve your desired effect

[unkempt moth]

I think I've watched this one @fiery swallow. But I might have to watch it again. Maybe my question wasn't completely clear. I want a hold button to aim and a shoot button to shoot. Not just over the shoulder view but an over the shoulder when aiming view. Does it cover that or do I need to adapt from what it is talking about?

[fiery swallow]

The way he changed the camera boom is how it can be done in the video, what I mentioned though

If you want an interactive camera that moves rather then teleports you'll just need to use VinterpTo node, alternatively you can use a timeline to achieve the same effect

Is how you'll achieve the effect of shoulder view when aiming

Are you familiar with VinteroTo node or a Timeline node?

[unkempt moth]

Only slightly

I'm working on my 2nd game and my 1st commercial game

Plus I've been using Unity mostly until a certain point

[fiery swallow]

In your case, I would go with a timeline since it's suppose to be a temporary thing

[unkempt moth]

Okay, I'll check the video out. Thank you!

[fiery swallow]

I can show you how to do it if you want

[unkempt moth]

Okay that would be a great help!

[fiery swallow]

join programming parlor voice chat

[unkempt moth]

Hold on trying to get the mic to work

[fiery swallow]

I guess you need special permission to screenshare so just sent you a friend request, you'll have to accept

[trim matrix]

does anyone know the name of this node?

[fiery swallow]

is it camera 1? ☺️

[trim matrix]

i mean im guessing??

im tring to figure out which one it is that target to the left thingy

if i drag camera alone with get or set it doesnt give me it

[fiery swallow]

I see a cast to node

a variable

and a set view target blend

the one on the left is a cast to node

[trim matrix]

yeah

but how do I get the middle one?

if i click on promote to variable it gives me that node instead

[fiery swallow]

so you're trying to get camera 1 from Dviz Game Mode?

[trim matrix]

yeah

idk im kind of in a mess rn

because im following a guide to be able to to access a camera

on this scene

so it says here to place the camera in the level

then get the reference

so maybe that step has to do with it

how do i get a reference from a camera thats already in the scene?

i already tried dragging it onto the event graph or components and it doesnt work

[fiery swallow]

So the way cast nodes work is... They give you all the variables and information from a different blueprint

the reason you can't get camera 1 when dragging off of it is because camera 1 does not exist inside of it

[trim matrix]

yeah

Camera 1 exists in the level

but its not referenced

because I dont know how to do it, I tried looking it up but i havent had much luck with cameras only

[fiery swallow]

what do you mean it exists in the level, it's not attached to any actor?

[trim matrix]

i have a camera actor to roam around

im trying to get a second camera so the player can look at specific thing from a specific angle. controlled with a widget

the plan was to let people click on it and use the camera for a bit and then go back to the roaming character

what I mean is this

https://answers.unrealengine.com/questions/298895/how-to-change-cameras-by-umg-button.html

on the second step is where im a bit lost cause i dont know what he means by get the reference (Like I know what he means but im unsure on how to do it)

[fiery swallow]

Okay so it's saying open your level blueprints and store these camera references in your gamemode

[trim matrix]

yeah

[fiery swallow]

So open up your game mode, create a variable that's an actor

camera actor

[trim matrix]

done

called it camera_1

[fiery swallow]

then go to your map and open up the level blueprints

should be at the top

somewhere around the toolbar

somewhere near the play in editor button

it's like a picture of blueprints

[trim matrix]

yeah

im on it rn

now it says thre cameraactor, from persistent level

[fiery swallow]

right click and click create reference

it will automatically give you a reference to that camera

it should say camera actor from persistent level

[trim matrix]

OH

wait gold on

[fiery swallow]

if it doesn't, you'll need to go back to the viewport and click on the camera, and then do it again

[trim matrix]

i created the cameras on the gamemodeBP not on the LevelBP

[fiery swallow]

yes that's correct

leave it

you can not reference the cameras properly in the actor unless you store it's reference in a reachable location, which is why you needed to create it in the gamemode

[trim matrix]

yeah bare with me for a sec

im redoing all the steps

im trying to find the level blueprint real quick

ur saying that its at the top

[fiery swallow]

look where the play button is

and go left of it untill you see some blueprint logo

[trim matrix]

got it

ok im here

lets see

[fiery swallow]

click on it and then click open level blueprints. okay

Go back to the viewport

and click on the camera

[trim matrix]

yea

[fiery swallow]

return to the level blueprints and right click and then click create reference

[trim matrix]

and drag it

got it

now its good

[fiery swallow]

you dragged it into the gamemode set camera actor?

[trim matrix]

i dragged it on to the level BP

and im building the nodes that are on the pictures

[fiery swallow]

okay

[trim matrix]

ok so

im trying to rebuild the nodes

but im having a hard time getting the set node

[fiery swallow]

cast to your game mode drag off of it and type set camera actor or whatever you named it

[trim matrix]

awesome

ok done with that

now

if i have that camera called "Driver"

3. Go to your GameMode BP and add variables of type Camera Actor (As many variables as their are cameras in your level)

I just have to add them by name?

or do i have to drag and drop from the Level BP

nvm I think I got it

@fiery swallow thanks for the help, appreciate it 🙂

[minor wolf]

So I was having an issue before where I had a widget with an expose+instance editable integer variable that was never actually being set even though I provided it with a value in CreateWidget. Just wondering if anyone knows how to fix this?

[open peak]

How do I clone an Actor and make it a child of the BP actor?

[tired cypress]

@open peak Right click the BP object in the Content Browser then select "Create Child Blueprint"

[tired cypress]

The Create Widget node just creates an instance of your widget. I don't think you can set variables inside the widget with this node (you'll need to do that after you create it).

[open peak]

But how do I do it in a blueprint function? I have a variable exposed to the user and i intent to have it run in the construction script

[minor wolf]

You can expose variables same as any other blueprint and I'm pretty sure this is the only blueprint that is not working. If I make a custom event to set the integer I get the correct value but none of my text widgets inside are updated

[tired cypress]

Are you wanting to create an instance of the blueprint? Or you are actually trying to create a child object blueprint at runtime?

[tired cypress]

If you use the CreateNode and are dragging off the return value, then you'll likely need to cast this to your widget type first in order to expose the var

[open peak]

I making a Repeater script where i can give it an actor and have it be repeatedly placed in the level

I come from a Unity background so im not completely familiar with the way UE does level objects yet

[minor wolf]

I am using CreateWidget as shown in this image https://media.discordapp.net/attachments/221798862938046464/881222403336839168/unknown.png

[tired cypress]

@open peak Yeah so all you want here is an object instance. Likely you'll use the SpawnActor node

[open peak]

But how do I provide it the Actor instance, it only accepts Class

[tired cypress]

Well if you specifically need the in-game actor instance, then you'll have to grab that at some point, really depends on your workflow here

You really can't provide it the Actor class?

[open peak]

It'll GetClass when i try to pass it the Actor but is it going to clone everything in the actor?

[surreal peak]

No

Blueprints have no logic to automatically duplicate afaik

You can grab the class and spawn a new one

But that's a fresh one

You would need to set all variables by hand

C++ could probably do it I guess.

[open peak]

But what if for example I have an actor in the level which has a static mesh as a child, it will only instantiate the actor and not it's children?

[tired cypress]

You can use GetActorOfClass in order to find an actor that has spawned within the level...but that doesn't specify exactly which actor

[surreal peak]

It will spawn a new copy of that actor with all default values

Child is a confusing word to choose here

Child usually means inheritance

So a child class. Not really related to spawning it or an instance of it

[tired cypress]

Yeah, if it has inherited components, then it will spawn all of them

[surreal peak]

Components are defined in the class so it will also create those again

If you changed the static mesh asset in it during runtime then that change does not exist in the new one

Only the default values will be there

[open peak]

https://i.imgur.com/7rwkP41.jpeg

So if i for example wanted to duplicate this floor with the cube

I can't really figure out how I could do that in a BP script

[surreal peak]

May i ask why you are doing that?

Is that a gameplay feature?

[open peak]

I just want to repeatedly place out any kind of level objects without having to do each one by one manually

But rather, provide what i want to repeatedly place out along a line for example

[surreal peak]

You would place some actor that has an array of actor instances in it

[open peak]

It's more as an editor tool i guess

[surreal peak]

Then you can reference those two actors via that array if they are all in the level

And let the additional actor spawn them via their class

That said. Constellations like this would probably be good to be created as one actor

Or the actor itself can spawn multiple meshComponents via construction script

Oooor you simply hold ALT while dragging them :D

[open peak]

But If i wanted 100 of them along the X axis i need to do that 100 times and be accurate with the mouse (unless i use snapping)

[surreal peak]

Yeah alt is more for a few copies

[open peak]

Doing it this way, I would be limited to Meshes only, right?

[surreal peak]

Yeah

[open peak]

I wouldn't be able to have repeatedly placed out AIs for example then

[surreal peak]

Correct

But there are also editor utilities you can use nowadays

Where you can script your own widgets that can get your actor selection and do things with them

Which might be a bit more suited for generic editor utilities

[open peak]

Yeah I was looking into that initially, then I found out about Constructor Script and gave it a try but no luck

[surreal peak]

Yeah an actor with a spline that places things along the spline via construction script is also a way

Hard to explain though without giving you actual code

[open peak]

I saw this before but wanted it with other things than just Meshes https://youtu.be/83Jd3HhADCU?t=3641

[trim matrix]

How would I be able to rotate a camera, but disable character rotation on key press for a thirdperson game? Any help would be greatly appreciated. Trying to get
a block stance locks character rotation(strafe all directions), but camera can look around. Or a video about it, I could follow. enabling rotation yaw and disabling yaw input works, but locks camera too.

[surreal peak]

Can't check the video. Currently 5am here .only up cause new kittens are crying.

Grabbing the actor class and spawning them again should work

[open peak]

He basically has a BP with a spline and has meshes spawn along the spline in the editor

[surreal peak]

Given your spring arm is controlled by control rotation, I think you only need to make sure the Orient Rotation to movement is false and that the character isn't also using control yaw

[cloud jetty]

Hey guys, just a quick question.
I'm trying to use "WASD" input action but it's not working. Is because it has been already used as an InputAxis ? And do you have any solutions for that ?

[trim matrix]

ty So easy

sigh all day struggle lol. I come here more 🙂

[surreal peak]

You mean you already set up inputs in your project settings and now you want to use the same keys again for a different input?

[surreal peak]

Did that help though?does it work now?

[trim matrix]

Yup! I always get confused with that stuff. I just need to turn on off Orient Rotation now in BP. Works perfect though 🙂

[cloud jetty]

Yea "WASD" are already used as an "Input axis" in the project settings for player movement

But I want to use them as an "Input action" To know which direction the player is moving to (For animation purposes)

[main sundial]

Hi, I am a beginner and want to create a simple character that can run and fall. I tried many tutorials and somehow able to make it run but it doesn't fall.

[surreal peak]

Hm check if disabling their consume boolean helps. Click the axis events and check the details panel on the right

[midnight ravine]

What do I use to create a data-based relation between stuff?

Here's my scenario:

I want to change the color of objects in my scene based on what category it belongs to. But I do not know how to describe the relation between a category (which is just a custom Enum) and their corresponding color vector. Can someone help out? I've looked into Data Assets but that doesn't seem to be right

[cloud jetty]

Check your "Gravity Scale" on your character movement

[midnight ravine]

define "falling".

[surreal peak]

Default characters should be able to fall

Unless this is not what is meant

[midnight ravine]

@main sundial do you mean "fall" as in have an animation play when the character is no longer touching the ground?

[surreal peak]

DataAssets are a bit advanced. They allow you to pull data out of your actor class and define it reusable in an asset

A dictionary like lookup can be done with a Map

[main sundial]

No, I mean it's not falling even if there is nothing below it.

[surreal peak]

What class did you use when creating your character?

[midnight ravine]

Map! That's probably what I'm looking for in case it means something like it does in general programming. Thanks Cedric.

@surreal peak would I be able to create a Map Asset that all my blueprints would be able to access game-wide though?

[main sundial]

I tried using pawn, character and player controller. But it didn't work. Which one should I use ? I am creating a local multiplayer game.

[midnight ravine]

I wound up using DataTables but have one question. Is my "category" column redundant and should I just use Name?

[tawdry raft]

Big question, would anyone have an idea how to make the camera move how DMC5's camera tracking works when fighting an enemy?

https://tenor.com/view/sunhilegend-vergil-devil-may-cry-dmc5-devil-may-cry-v-gif-20023500

https://tenor.com/view/nero-devil-may-cry-combo-cool-explosion-gif-16723273

I keep thinking maybe a spline could work?

[ivory adder]

So I have a weapon that takes 5 seconds to be able to fire again. I would like a progress bar on the HUD that displays the cooldown. How would I do that?

[light garnet]

Is there any online subsystem for mobile ?.

[minor wolf]

would it just use like google/apple services?

[midnight ravine]

DMC used a combination of splines and general actor tracking.
The math behind it is complicated and you're probably better off writing it in C++ because it'll get messy real fast in BP I reckon.
Take a look at some custom camera systems other people have written.
https://github.com/donanroherty/UE4_DarkSoulsCamera
https://github.com/mklabs/ue4-targetsystemplugin
https://github.com/redcatbox/CameraVolumes
https://github.com/joessu/DynamicCameraSystem
https://github.com/historia-Inc/UE4_AimCameraPlugin
https://github.com/jlamarche/ExploreController

You might want to use a CineCameraActor instead of the regular camera actor as it offers more features out of the box such as actor-tracking.
You'd need to tweak that though to get the effects you're hoping for.

You might also find the source code of Unity3D's CineMachine useful: https://github.com/Unity-Technologies/com.unity.cinemachine

[desert rover]

I have this 2d sidescroller game and on the blueprint I can move my mouse around and my player will look in the direction of the mouse and shoot, I want to implement a controller thumb stick instead of the mouse but i cant figure it out.

[feral jay]

So right now I have it set to spawn 1 of every type of die on pressed. how would I have it spawn a specified amount of each die.

[plush swallow]

why cant i move instanced meshes on runtime

like is it possible to set the location of each instance at runtime?

[tight schooner]

Like with a hierarchical instanced static mesh component? Yeah you can set locations of individual mesh indexes or update them all in batch. There are nodes for that.

[plush swallow]

i used the update instance transform and it didnt work

[tight schooner]

Did the instance index exist before you used that node? That's all that comes to mind offhand for why it wouldn't work

The update node doesn't create the indexes IIRC

[plush swallow]

i created the instanced meshes in the construction script using add instance

and then i use the update instance transform in the event tick

the instances are generated but they dont move

w8 now they are moving

i was using instanced static mesh instead of hierarchical instanced static mesh

but i dont get it isnt hierarchical used for high poly meshes that need LOD? i didnt use it because my instanced meshes were just cubes

[trim matrix]

hey all, having trouble wrapping my head around bp communications.
Trying to reference a variable between to blueprints.
without using interfaces can I make the below work?

[minor wolf]

you need an object to cast

if the blueprint in the picture is of type BP_MoneyGeneration (eg it derives from it) then you can use a "reference to self" node

otherwise, you will need to procure a reference to it from elsewhere

[trim matrix]

There are numerous ways to get references as well, so you should definitely check up some online resources on casting.

Yeah i;ve been reading the UE doc but I'm just have trouble interpreting it. Got the cast to work a different way for now.

If all else fails you can create a variable that is an object reference

I ended up putting the variable into my player and calling it with a cast on collision =/

[desert rover]

This is the code to get my sidescroller character to look at my mouse cursor and shoot bullets, but i want to add gamepad controls with using the gamepad thumbstick to aim instead of my mouse. any one got any ideas?

[fallow orchid]

hi! did you resolve it with custom angle?

[trim matrix]

I have a question, why do we need casting?
My question arises from this:
https://cdn.discordapp.com/attachments/127723854171734016/881446940670328943/unknown.png
https://cdn.discordapp.com/attachments/127723854171734016/881446992209920041/unknown.png
In both of these images I am accessing the 'box', a collision box belonging to the ThirdPersonCharacter
Why do I need to cast, if using an object reference also works, are these two things synonymous, or do they serve different purposes?

[minor wolf]

you only need casting when you have a type T and want to use it as a type U where U and T are related. if you have a type of Controller and need to use it as PlayerController or you custom player controller bp/class, then you have to cast. if you dont, then you dont need to cast

[trim matrix]

I see it is all about type T and type U

time to google what those terms mean, thank you.

[minor wolf]

they are just type names

if it helps, T is Controller and U is PlayerController

substitute them accordingly for the types you want to cast to/from

[trim matrix]

So as long as my casts aren't dealing with a Controller/Player Controller I don't need casting?

[minor wolf]

that is incorrect

you only need casting when you have a type and want to use it as a different type where types are related

[trim matrix]

I see, any types not controllers specifically.

[minor wolf]

Controller is a type

if you mouse over the output pin in GetPlayerController it will say it returns a Controller

if you look up the docs page from Epic it will tell you that PlayerController is a type of Controller

its all about the hierarchy of types, or "classes". in blueprints, each blueprint is a class of its own

ThirdPersonController im pretty sure is a type of PlayerController because its parent is PlayerController

not sure about your ThirdPersonCharacter, maybe im confusing names

[trim matrix]

I am using get Player Character, ThirdPersonCharacter is just the name of the default BP class in the ThirdPerson Demo

[minor wolf]

let me check it real quick

so it says in ThirdPersonCharacter that its parent is Character

makes sense given the name, however there is no direct relationship between Character and Controller

the docs page sheds more light on this

the closest common ancestor for Controller and Character is Actor

however you should be able to do GetPlayerPawn -> Cast (ThirdPersonCharacter)

[trim matrix]

Since Pawn is higher in the hierarchy than ThirdPersonCharacter?

[minor wolf]

theres no way to get a ThirdPersonCharacter directly from a Controller

best you can do is get the pawn (since Controller has this function), then downcast to your character class

[trim matrix]

I somewhat understand, further study/experimentation definitely required.

Hey Gambit, there is this casting based snag I am running into could ya guide me a little?

[minor wolf]

sure

for further reading you can check the wiki page https://en.wikipedia.org/wiki/Type_conversion

also check this out https://en.wikipedia.org/wiki/Inheritance_(object-oriented_programming)

[trim matrix]

So I made an actor called Pickable, and then made three child blueprints so that I can add all the functionality into the parent class while I can customize some of the stuff like meshes and variable values in the children.

I then made a data asset called Inventory and made an array of type 'Pickable' to store objects of the children.

I am trying to 'get' the inventory into the BP for the parent 'Pickable' Class but it hits me with the accessed none error.

Images for reference

Ah I see.

[plush ridge]

why doesn't cloth work on LODs above 0?

[main sundial]

How can I make my character cover fixed distance on every jump. I want my character to jump from platform to platform.

[earnest tangle]

As in, automatically cover a specific distance for the jump?

[main sundial]

Yes, I want my character to cover distance just by jumping.

[earnest tangle]

Right - and the jump distance must always be the same, and not affected by things like other inputs or the character's speed?

[main sundial]

Yes, My character can not move. It can only jump.

[earnest tangle]

Ah I see

You could perhaps use Launch Character

I think that's what it was called

If you give it an upwards vector into the direction you want to jump with sufficient force, that should do it I think

[formal wren]

Anyone have an idea how I can watch the value of an variable and trigger an event in the moment a certain threshold is reached? I don't like the idea of using Tick for this

Maybe using a special setter function?

or is there a better way

[earnest tangle]

It depends on how you're updating the variable I guess. If you tend to update it on tick, then checking for it on tick seems fine. If you only update it occasionally, using a setter function would be the way to go

[floral quail]

My input is not executing at all even though i have it set up in Input. I can see the execution when other events fire. Any thoughts on why?

pls @ me btw

[fiery swallow]

there's likely a key already using the same key as crouch, assuming it's placed in the actor you're controlling

[surreal peak]

Where is that placed in

Because both Character and Controller wouldn't need that amount of nodes to trigger this

Ah well controller maybe but then GetControlledPawn would be better

Either you are using the same input or the key itself somewhere and it's being consumed or you are in object that has no input enabled

[floral quail]

Can you expand on this Either you are using the same input?

[surreal peak]

Inputs are handled on a stack

Means one after another has a chance to utilize an input

[floral quail]

Any way to check for multiple actions bound to same input?

[surreal peak]

Each can say they can consume the input which will remove it from further handling

E.g. if your Playercontroller has the event and your character and your controller consumes it, the character won't get the event anymore

[floral quail]

That makes sense, consuming the input is optional then?

[floral quail]

Any way to get a consumption stacktrace or the like?

[surreal peak]

Hm maybe via cpp breakpoints

But generally you should know if you used that input elsewhere

And consuming is optional but enabled by default

You can click on the input node to disable it on the right

In the details panel

[floral quail]

Currently I'm only using the default fps controller. I wanted to add crouch. The event is something I added. I also have a global event that toggles some light on ctrl, would this be the culprit?

[surreal peak]

It's also important to answer the question as to where your code is even located

[floral quail]

I'm new to blueprints

[floral quail]

This is probably why I think

[surreal peak]

It could very well be the issue

[floral quail]

Thanks man 🙏

Learned something new

[surreal peak]

Input for your character should be in the character

Controller input should be for things that have nothing to do with one specific character

[floral quail]

It is in my character

[surreal peak]

Like opening a menu

If it's in your character why are using so many nodes

[floral quail]

The other thing was just to test some quick and dirty blueprint

[surreal peak]

You can call crouch directly

[floral quail]

How would it know the type?

[surreal peak]

Wdym

You are in your character

[floral quail]

Ah

[azure vale]

Hey Guys I have a question for something I thought would be easy.

I have an Enemy Actor, which goes into ragdoll if hes dead. I wanted to add an impuls so that he flyes away on death.

But the ragdoll does not react to that, just falls to the ground.

[hexed cloak]

Custom point in bounding box with rotation works by taking the bounding box’s world position away, applying rotation, getting random point, and adding back the world position.

[surreal peak]

Even with an insanely high number?

[azure vale]

@surreal peak is this enough?
😂

[surreal peak]

Just making sure. Forces are sometimes a bit random

Also the direction is inverted

[warped cloud]

Does anyone know of functionality to copy text to the system's clipboard?

[surreal peak]

Probably something something platform

But not via blueprints

[warped cloud]

yeah google didn't reveal anything; I guess I'll look for plugins!

[surreal peak]

Yeah it's gonna be c++

Either something with the platform interface or directly via windows apis

[azure vale]

I know, im glad for any help^^

Is there maybe another approach to apply force/velocity directly to simulated ragdolls?

[floral quail]

how would you reference own instance of character for crouching

[trim matrix]

Wow autosaves just saved me

I first compiled an asset after some change in the BP code and it made crash the editor

Then I opened the project again, and made the same changes to the editor, then saved first then compiled the asset and it made crash the editor

then after that everytime I tried to open the project it crashed endlessly o_o
I had a brief moment of panic

then I remember there was this "Autosave" folder and it just saved me wow

[floral quail]

Aight, this actually just works

[surreal peak]

Nice and now stop relying on that and use #source-control like every other sane person

[trim matrix]

Oh yeah, that's a thing, you're right, thank you !!

[lusty elbow]

Which would be the best way to create a persistent log? Using "print string" with very large values of Duration and short string works for now, but I am looking for a clean permanent solution.
Here's an example. Combat log of the game Battle Brothers

[lusty elbow]

New lines appear at the bottom, as if we were writing it, unlike the "print string" where it's written at the top and pushes the other lines downwards.

[loud cipher]

anyone know how i can make a blood vignette appear the more the player gets hurt?
e.g.

https://cdn.discordapp.com/attachments/221799467689574410/881519169944829952/unknown.png

i want the health to increase the alpha so it appears more the player gets hurt
so at 100 hp alpha is 0, at 50 hp alpha is 50
how can i do this

[willow breach]

someone pls help in #ue4-general

[surreal peak]

Print string is for debugging only. You are aware of that right?

[lusty elbow]

Yes. Hence my question.

[surreal peak]

Post Process effect for example. I'm sure you can find tutorials about that via Google

[surreal peak]

UI is done via #umg

[lusty elbow]

Yes. Any pointers on how to do that kind of log?

Ah

Wrong channel

My bad!

[surreal peak]

Spawn widgets into a vertical box

[lusty elbow]

I will ask in the #umg channel. Sorry for cluttering

[surreal peak]

Oki

Hi! I tried to make an angle calculator system to calculate the angle between the lines, but something doesn't work correctly. Any idea?

[azure sparrow]

Hey i needed a help regarding the interface thing

So i have an interface named interact interface

And im trying to call it

whats the difference between these two?

and also i am calling this on a widget (If that makes a difference)

For some reason this isnt getting called

[random quail]

left is event provided by interface (interface call) , right is a regular event (regular call)

[azure sparrow]

but i cant seem to find the one at the left anymore(not for the interface or for any other)

nvm i found now lol

it wasnt showing up for some reason

[willow breach]

how do i make this 2 peices instead of one?

[azure sparrow]

u should do it on ur 3d Software @willow breach

[willow breach]

its from sketchfab

i downloaded it

i just wanted to know if i could split it @azure sparrow

[zealous moth]

I am trying to populate my UMG widget horizontal box with buttons based on a list. I put a print string to catch whether or not the button gets constructed and it does however it does not appear in the horizontal box. In fact it looks completely collapsed. Anyone encountered this?

[azure sparrow]

yeah u need to do it on a 3d software : )

[azure sparrow]

not add child but add child to grid

[zealous moth]

hm, it's not a grid per se but I did change it to add child to horizontal box.

the result is the same

looks collapsed in the corner

bottom left

my button structure looks like this

if i set size to content, it will expand to something more or less acceptable but I want to to fill all..

[willow breach]

...

[zealous moth]

Alright so the solution was to cast off the child for the sloy and set that slot size to fit

[latent basin]

Hi guys, one of my project files has somehow been currupted, and now I cannot open it or interact with it anyway, even though the game shows the file, therefore I know it is technically valid, just anytime I try clicking it or opening it the editor crashes. Can I somehow fix it? i spent some time on the file and would really like not reworking it.

[midnight ravine]

@latent basin that's why you should use #source-control

[latent basin]

😦 ok

[fiery swallow]

Do you have autosave on? :)

[latent basin]

well im not sure

this is my Saved folder, there are Autosaves but no Backups

[fiery swallow]

get the autosaves

[latent basin]

It Worked!!!! yaaaaaaay

thanks

[azure sparrow]

??

[surreal peak]

Get #source-control anyway. It's insane to work without. One unlucky moment and your project can be toast

[tawdry raft]

Thanks for the answer, I'll take a look at these although I have 0 experience in coding, I'll have to ask a friend to help me with this

[minor wolf]

does anyone know why my text widgets are not updating? i can confirm this being executed (via PrintString), however the changes are not reflected in the actual widget

using bindings instead does not work. just the widgets to default value of the variable

doing this in tick with bindings yields the same results as just using bindings in construct. in tick without bindings and setting the widget text directly is the same the first game picture with the prints, the values its setting are correct but its not reflected in the widget itself.

setting the ServerItem text widgets text directly from where the session information is available also does not work, same result as the first game image with the prints

i decided to print the text values when i click the button and can confirm the values are not being set at all.

session info is definitely available

[sinful saffron]

anyone got a problem with blueprint not reciving keyboard input?
I put in enable input on event begin play, but event with key Y is not triggering.

[minor wolf]

turns out ListView is the reason. maybe i was using it wrong and i should have been using the Entry Initialized event, but i swapped the ListView for a VerticalBox and its working fine now...

[marble nova]

Quick question on best practice - is there any reason to limit the number of levels you can stream? - eg i'm making a puzzle platformer & i'm streaming all levels into a single main level and unloading the previous for better loading. will i encounter some kind of limit on how many levels i can include?

[sand shore]

You shouldn't, but it's always a good idea to try to not have as many levels present.

[tawny river]

anyone have a good reference on getting a projectile to be lobbed in a ballistic arc from point A, to point B

I know there are built in nodes for it, but I've always struggled to get decent results out of them (if any results at all)

[marble violet]

where can i find Blutility.GlobalEditorUtilityBase class?

UE 4.20.3 has it but i can't find it in 4.26.2

[earnest tangle]

Have you enabled the plugin? I recall Blutility was one that's not on by default

[marble violet]

I can't find Blutility in experimental section of project setting in 4.26

in 4.20 it was in Tools tab

i think in 4.26 is not experimental anymore @earnest tangle

though i can create Blutility but I can't find the GlobalEditorUtilityBase

[worthy tendon]

wonders

[earnest tangle]

It still exists on C++ side, but it's marked Deprecated, so you probably wouldn't want to use it

[marble violet]

oh damn... then probably I have to use Editor Utility Widget instead

thanks for the help

[open peak]

how do i get all the children of an actor?

[maiden wadi]

@open peak Children in what sense?

[open peak]

the two attached actors here

[maiden wadi]

If Repeater is your actor, you'll call Get.. Editor isn't open at the moment. I think it's something along the lines of GetAllComponents, or GetComponentsOfClass if you want just the static mesh ones.

[open peak]

There is this but it doesnt work https://i.imgur.com/FtyrTCl.png

[maiden wadi]

Where are you calling that? Inside the blueprint of Repeater?

If not, the target needs to be Repeater.

[open peak]

Editor

[open peak]

https://i.imgur.com/hpP48Ax.png

[earnest tangle]

Note that Get All Child Actors returns child actors from child actor components - if you just attach actors into another actor, that won't return them.

[open peak]

then how do i get the attached actors

[earnest tangle]

Get Attached Actors

[maiden wadi]

Oh. I totally overlooked that. I didn't realize those were actors. I read that as StaticMeshComponent. 😄

[earnest tangle]

yeah wasn't sure if it was child actor comps or not, just thought I'd mention it just in case :)

[open peak]

This only gets half of the attached actors

[maiden wadi]

It gets all of them.

If you're trying to clear them, you need to do it in reverse.

[open peak]

it doesn't

oh

[earnest tangle]

ah the classic pure node footgun

[open peak]

ah i see it reads from the array as i delete them

How do i save it to a temp variable then? Local variable?

[earnest tangle]

right click the array return pin and choose promote to variable / local variable

(locals are only available if you're in a function)

[maiden wadi]

Likely easier just to use a reverse for each loop.

[earnest tangle]

yeah that would work, although it'll still keep re-calling the node every iteration I think

it's probably not really a huge problem tbh

[open peak]

I did this and it works well now 🙂 thanks

before, i was just connecting the out array directly to the foreach, as zomg noted

[earnest tangle]

Yeah, it's good to be aware of the behavior with pure nodes where they get ran multiple times in some situations like this

They can occasionally cause bugs which can be hard to figure out unless you just know this is how it works

[open peak]

How do I get the mobility of an actor?

[earnest tangle]

isn't there like a get mobility node or something (it's probably for components, since those are the ones that have that, not actors)

[open peak]

ah so i have to probably get the scene root component or something?

[earnest tangle]

yeah whatever is the root of your actor

[open peak]

Is it possible to multiply a whole transform or i have to multiply every vector by vector?

[turbid orbit]

What is the correct way to reference character height?

For example here I can use "Third Person Character" to get "Character Movement" then "Max Walk Speed". What do I type to get the correct value for player height?

In case my intention matters: I want to make the Height a variable just like I did with MaxWalkSpeed so I can reference it elsewhere in my Animation Blue Print

[modern musk]

Hey everyone, I did some googling and playing around with this a couple months ago and couldn't come up with anything, I'm just making another attempt and thought I'd ask here:

When attaching a mesh to another mesh's socket (currently working with skeletal but it would be useful to know for static as well), is there any way to snap one socket to the other?

For instance, let's say I have a sword with the origin point set to the hilt, but I want to snap that weapon to character's back when it's sheathed. In my mind, I thought I would just be able to create a socket midway down the swords blade, create a socket on the characters back, and snap those two sockets together. In actuality, I'm having to attach the sword to the characters back socket using the "keep relative" option, and then manually adjust the sword's transform so it fits properly, then save that variable and call it when sheathing the weapon. This works fine for a couple weapons but becomes tedious in a game with customization. Anyone able to point me to a better solution?

[zealous moth]

@modern musk use a placeholder for the weapon socket and rotate/adjust and record it. It will be tedious since it aounda like your weapons arent standardized

@turbid orbit i am confused as to how it is relevant. You can get your characters capsule height for instance.

But if you want the exact height of your head to your root... use measure on 2 sockets? Or get bone locations and get distance

[modern musk]

Hey, thanks for the response, yeah that's pretty similar to what I've been doing (sans the intermediary object). Although, you make a good point re: standardization, maybe I should focus more on ensuring weapon types (e.g., 1H_Swords, Spears, etc.) are roughly the same shape/size so that it only needs to be done once for each category.

[zealous moth]

@modern musk on the static meshes you can add a socket and rotate it as needed and use that as a point of reference when attaching it to something else

For instamce, i had some swords where the handle was at origin. However for some daggers they were not. So i added sockets to all and make the xyz coords rotate so when you equip it uses that data to correct it

[abstract gate]

in VR the GrabComponent will orient and grab the object correctly. Is there any way to modify this or duplicate it to grab 2 places?

at once? It releases the other hand when I do this

[atomic salmon]

You can’t do two hands with an attachment technique

[abstract gate]

can i use the attachment with one hand then do the collision thing with the second hand?

[atomic salmon]

Check out my tutorial here: https://youtu.be/wxKYgJmc5a8

[modern musk]

That's what I'm working at right now, basically, take the socket transform relative to the origin and then use that information to attach the item, I think is the general idea?

[feral ice]

how do i save each instance as an item in a list? Or is that possible? If I want to access instance 6 and change its rotation for example, how do i save in list?

[zealous moth]

@feral ice take mylist and pull off "add"

However in this case use a map

[feral ice]

ok

[abstract gate]

@atomic salmon in your video you are using a static mesh but it should be fine to follow it with a skel mesh correct?

[minor lynx]

is there a way to make the water bodies act like a physics body set to water? seems odd to have to also maintain a separate volume to say hey this is water but i cant figure it out

[trim matrix]

ok so I have set up cameras on the scene with widgets and if the player wants to go and look at things from these cameras perspectives it will switch up from the main character camera to the cameras in the scene

one issue im running into is that if I want to go back to the main camera, I cant because i havent figured it out

im on the Level BP and this is what I created with nodes to see if I can jump back into the character after interacting with one of the cameras

but it brings me back to where the player first starts and I cant move

Im trying so if the players Clicks E, he can just go back to where his body was before swapping to the camera. It would be efficient if I could just set up an UI inside each camera to tell the player "Press E to go back" but thats something I want to do after I figure this out

[minor lynx]

i think you need to target the pawns?

because switching camera doesnt switch which pawn you are controlling

you can probably getpawn from the controller to know where to reattach

[trim matrix]

okay let me try that!

that actually worked

[minor lynx]

awesome

[trim matrix]

but its using the optional camera pov/height

and not the characters one im using

so i have to figure out how to use that one instead

[minor lynx]

im not sure about that

im a unreal noob 😛

[trim matrix]

yeah me too haha, im trying to get used to the blueprint system

theres a lot

@minor lynx got it working, I needed to use the get player pawn node

connected to view target and then get player controller for target

[minor lynx]

awesome

[feral ice]

Can you use I as in complex numbers in ue4?

[turbid orbit]

I dont know why youre asking about relevance. I just want to know what to "get" so I can have the characters height as a variable.

[atomic salmon]

Yes, works similarly.

[atomic salmon]

No, but why would you?

[marble violet]

How can i render a Material into TextureRenderTarget2D without dropping it into the scene?

it's always black, except I add emissive into the material

[zealous moth]

because typically, a capsule colider is used to delimit your character with a root position and a height.
so when you ask about your character's height, i'm not sure why that would be relevant.

[marble violet]

i have a simple material

Trying to render it into TextureRenderTarget2D

it's black if there is no emissive

i believe is because there is no lighting

since i'm just doing it within the content browser

[feral ice]

Just curious

[earnest tangle]

rendering a material to a render target doesn't really have anything to do with lights, and you can't really do it in the content browser either, so I'm not quite sure what exactly it is you're doing here

[marble violet]

and I made an Editor Utility Widget

[earnest tangle]

Ah something like that

[atomic salmon]

There is no support for complex numbers in Unreal. You would need to write your own library or use a C++ one.

[marble violet]

basically i pick material and RenderTarget and render it

[earnest tangle]

If you use Draw Material to Render Target I'm fairly sure it should work, but tbh I'm not sure how the editor treats RT's when you're just using editor utils like this

[marble violet]

yeah, I'm doing Draw Material to Render Target

it works if there is Emissive

[earnest tangle]

Ah

Yeah it might have something to do with how the editor captures the thumbnails

Why are you trying to draw into an RT in editor utilities anyway?

[turbid orbit]

I dont think the why even matters. And as I said I want reference it in an Animation Blueprint.

[marble violet]

some of my texture are fairly heavy trying to optimize them into a single image

[zealous moth]

then i gave you and answer, enjoy~

[earnest tangle]

You would probably have to generate an actual texture2d asset from them, I'm not sure if you can really save render targets like this 🤔

[open peak]

is it possible to multiply a vector by float

[marble violet]

@earnest tangle I was watching UE Material Master Learning by Sjoerd de Jong, and in "Render Target" section he did that in UE 4.20 so i thought that is an interesting approach

[earnest tangle]

interesting if that would actually work

I know you definitely can generate and save texture2d's, but it has to be done in C++

but maybe it's possible to save the RT's as well, but I guess you might just not get a good preview for them unless its emissive

[earnest tangle]

Yes, there's a node for it if you search using *

[marble violet]

hmm... i thought maybe i missed something somewhere

[ashen panther]

can you change a splines lentgh at runtime? so that it retracts and extends?

[earnest tangle]

Don't really know if there's a lot of folks doing that sorta stuff especially in blueprints so it might be a bit hard to find info on it unfortunately

[earnest tangle]

Pretty sure you should be able to edit the spline point locations to do that, or just adjust the scale of the spline component

[ashen panther]

if youre in ue5 you have to get the multiply node and then right click the pin and change it to float

[ashen panther]

thanks!

[marble violet]

thanks for the help

[paper vapor]

are there any tutorials for dynamic mesh painting with multiple colors?

[spark nest]

Hi there, I'm pretty new to UE and Node stuff in general, I'm currently following along a post on making drag-able widgets for a pseudo operating system and this node wasn't explained very well (at all actually) Could someone identify it for me so I can do some wider reading? I thought it was a Math expression but those don't seem to factor inputs (at-least from what I've seen so far) Many thanks in advance

[runic plinth]

It doesn't sorry I just took your latest message.

[marble nova]

I have a static mesh which im using 'anim to play' on inside a blueprint - is it possible to use a blendspace and then modify the blendspace value in normal blueprints, or does it need to go through an anim graph?

[abstract gate]

under custom it says there is the ability for two hand grabs. This is UE4.27 and i am struggling. it isnt like the older youtube videos

[marble nova]

managed to get this far but im not sure this makes sense

[spark nest]

(Apologies for repost, got buried) Could someone identify the circled node for me so I can do some wider reading? Cheers

[worthy tendon]

its just input key comparison. right now it's checking if pressed key is equal to left mouse button

[spark nest]

Awesome, I had a feeling it would be obvious. Forest through the trees and all that. Thanks for the help 🙂

[iron heron]

Hey can someone maybe help me

This is my character blueprint

i built some logic to change the movement input on "ctrl" and reset it once "w" is released

but i can't seem to go faster even after switching

when ingame and debugging i see it switching over, my logic is working

but if i pass more than 1,0 into the add movement nothing happens

[sinful sequoia]

Can anyone advise - why "IsFaling?" returns "false" when I'm in fact falling?

[iron heron]

it#s basically like minecraft

i want ctrl to enable sprint while holding forward

and to reset this state after letting go

[sinful sequoia]

Dont think this is relevant but ok

Also false under any condition

Ugh.... alright, thank you

[iron heron]

then you have to hold control

that's very fatigueing

wait

i butchered that word

my pinky is thanking me later

[runic parrot]

Hi! one question with player controler/UI.

I have 2 maps

1. LoginScreen
2. CityMap

I want to use a specific player controller and HUD for the login screen, but i'm not sure on how to change the player controller when changing between maps (there is going to be more maps with diferent playerControllers).

Is this the right approach? if so, how can i change the player controller?
i think i can change it swapping the GameMode to another one that has the new player controller as default, but how do i change the GameMode at runtime on new map load?

Yeah, that is the way, thanks!.

[iron heron]

Ah no its not

its release forwar button and go back to normal walking

so everytime you walk again you have to toggle sprint on again

[tawdry raft]

Where would you recommend I start for this feature?

[open peak]

is there an event for when the actor is deleted from the level editor?

When I delete a parent actor, the attached child actors are not destroyed with it, but rather moved to the world

[raw orbit]

is there a way to have a button widget parent for all buttons in my project for styling purposes? otherwise its a pita to change the color / image / font of every button when needed

[zealous moth]

@raw orbit afaik no there isn't. You'd have to make an array for your buttons and do foreach loops and set the properties

[raw orbit]

[raw orbit]

what about cpp, creating my own improvised button there

[zealous moth]

you can create a class or a struct that defines those things and then a function

[raw orbit]

oh okay. another question is there anyway to keep manipulating a synth 2d slider even if im outside its bounds

[zealous moth]

No idea what that is

Lol i used ue4 since 4.20 and i never heard of that

[raw orbit]

oh, its like a 2d slider, you can slide across a square

got x and y

[trim matrix]

Does anyone know why I cant get this node to work inside my blueprint

i need this action to happen once only so it doesnt keep making widgets on top of each other

i want the person to use a key on the keyboard to make it dissapear once they get out of the UI mode, but for some reason keyboard nodes dont work inside my blueprint?

nvm figured it out

[iron heron]

Basic Movement and movement based camera tilt

[midnight ravine]

No one can give you a step by step on this. Watch some tutorials on YT I guess. "DMC camera ue4"

[tawdry raft]

There's none at least close to it

I'm just not sure where to even start

[midnight ravine]

@tawdry raft maybe put in a bit more effort looking up stuff.

https://youtu.be/_TZ37WpOWgY

Again, what you're trying to do is a massive undertaking and you will not find a cookie-cutter solution.

[tawdry raft]

I was watching that just now lol

Though, if I had a combat system atm, my current camera would probably behave similarly, but not exactly as in the video

[trim matrix]

how would you guys delay flip flop animations?

i need one action to be done before option B can run

currently the user can spam and it messes up the animation

[midnight ravine]

@trim matrix make a boolean variable ranActionNeededForB. Set it to true when the function needed to run ran. Probably set it to false when B has been executed. Create a branch with the newly created bool as its condition, if true execute B, else execute the function needed to run B.

[trim matrix]

@midnight ravine let me try that out

@midnight ravine im trying to follow but im kinda new to the blueprint system

i created the variable and the branch

but still im trying to figure out how to connect it properly to make it work

[midnight ravine]

Show @trim matrix

[trim matrix]

@midnight ravine

[midnight ravine]

@trim matrix

Set var to true when timeline A finishes. This is probably what you want.

assuming you want B to only run (close door) when the open animation has finished.

A better variable name would be "IsDoorOpen?" for your context btw.

[trim matrix]

i just tried connecting flip flop a to play from start and flip flop b to reverse

and it does what I want

now I need to sync the sound when to door opens and closes

i know your way works as well

but seems a bit more complex than what I need dont you think?

[midnight ravine]

it's not complex. It's literally a condition you check for and common practice AFAIK. Do what you want anyway. Your solution sounds cool alas I probably wouldn't know how it works at first glance.

[trim matrix]

this is what I did

first sound matches when the door opens

[dawn gazelle]

That'll still give you issues with your animation.
Eg.
I interact -> it starts to animate the door opening from the start
Before finishing the animation, I interact again -> the door begins to close from the current position
I interact once again before the door is finished closing -> the door begins to open from the start

You need a boolean in there to check whether or not the animation is in progress and if so, go to "play" and if not go to "play from start"

[trim matrix]

but then im trying to see how to make it work so its sync with the animation

I see

let me try out that way then

[mortal cradle]

is there any issue with not adding return nodes to functions? bp always continue properly without them anyway

[trim matrix]

@midnight ravine

so it works when it comes to animation B waiting for A to be done

but I can still spam A

and it messes up the animation

I thought about connecting a branch node with the door open unchecked to the timeline_0

and connect the boolean node to the "finished" output of it

like so, but its not working

[midnight ravine]

@trim matrix Here's an alternative. Remove the current stuff. Make new bool IsDoorAnimating. Place a branch node in front of both timelines, check if isdooranimating. If it is NOT, run the timeline.

On both timelines set isdooranimating to false after the timeline has finished (drag off of the Finished pin).

[trim matrix]

@midnight ravine awesome thanks

I will check it out tomorrow

been working on this all day

[maiden wadi]

@mortal cradle Not really. I usually add them just to be explicit. But if you don't add them, then any failed control path will simply return defaulted values in any return value. IE False Boolean, 0,0,0 vector/rotator, 0 integer/float, etc.

[void comet]

Hey mates. Wonder if anyone can help me with some vector math. Not my strong suit. Here I have where I spawn my projectile. Takes position of arrow I have set up to follow mouse and its rotation to spawn the projectile along its forward vector. After projectile is spawned I set its velocity and multiply it by a float which is my charge counter so that it flies faster the longer the charge. Problem is that its also making my projectile spawn further away from my character the longer the charge. How can I increase its speed but have it always spawn in same position?

Is there a way to cast to every actor that's the same in my level and trigger a event in them?

ah well just worked around it by making a manager bp for it

[river pine]

Hi Guys, what am i doing wrong? The Weapon spawns in the Holster tiny

[gentle urchin]

Ur getting the holsters scale ?

Transform includes scale... dunno how big the weapon is in terms of scale relative to the holster but that could be the issue

[river pine]

yes that codl be it, Transform includes scale... ok gotta google it 😄

[void comet]

Can anyone help me with some vector math. Not my strong suit. Here I have where I spawn my projectile. Takes position of arrow I have set up to follow mouse and its rotation to spawn the projectile along its forward vector. After projectile is spawned I set its velocity and multiply it by a float which is my charge counter so that it flies faster the longer the charge. Problem is that its also making my projectile spawn further away from my character the longer the charge. How can I increase its speed but have it always spawn in same position?

Or I should say how can I increase its speed but have ti always spawn the same distance from my arrow

[gentle urchin]

Doesnt projectile speed do what you want in terms of launch speed?

Not sure why this would change the location tho.. except if its like calculating the velocityand updating the arrow location in the same frame its spawned or smth

[void comet]

I am applying custom gravity to the projectiles on tick and velocity overides the inital speed variable

So I have to do it with velocity

I can't really work out why its affecting my spawn point of the projectile either. But it is obvious it is. Adding more to that float that im multiplying before setting the velocity drasticly changes spawn point. Low numbers my projectile is slower and spawns at my offset, higher numbers make projectile faster but it spawns further and further away the higher it is

But the spawn point is set by that transform that is based on the arrow that has nothing to do with the float

[gentle urchin]

So it would seem its using the velocity the same frame its spawned ..?

[void comet]

I guess. How can I nullify it without losing the speed

[gentle urchin]

No clue really, I'd probably just use a socket to tie it in place, and unattatch it once its ready to fire, with the new velocity

Or have velocity at 0 untill it actually fires? Does that work?

Seeing how you spawn and update velocity at the same time, makes me wonder if you have a secondary arrow for the player just to visualize the drawback? And on release you spawn this arrow and swt its velocity?

[void comet]

Seems like a problem that could be solved with vector maths rather than a workaround..or was hoping

[gentle urchin]

Increasing the offset based on velocity

[void comet]

Yer I was coming to similar conclusion

[gentle urchin]

Or based on the same float you're multiplying velocity with

You just need to figure out the values

[void comet]

Its just its kinda unusual behavior so thought id done something wrong tbh

[gentle urchin]

130 min, .... 260 max?

Well im surprised if this actually is what we think it is (projectile using velocity the same frame its spawned)

[void comet]

IKR. Seems weird since even small values change the spawn point quite a bit

[dreamy basin]

can anyone help me i wanna make a blueprint for a gate which open after 30 sec do anyone suggest me similar tutorial or smthg else to useful for this topic

[gentle urchin]

You could try adding a 1 frame delay before setting the velocity

[void comet]

Ill try that now

It just kinda does same but sticks for a frame near the char

then teleports to that further point

[gentle urchin]

Teleports?

Got low framerate?

[void comet]

nope

[azure sparrow]

Hey i am trying to use a switch to string node in such a way that where i can give a condition where i will be using 2 strings as input

how to do that

i want to use both as inputs

then if any of the string matches the outputs, it will trigger

How to do that

[desert rover]

anyone know how to get aim offset working in a sidescroller using a controller thumbstick?

[gentle urchin]

You could append them but not sure that'd be the best way.

[atomic salmon]

@azure sparrowthere is nothing like that, so you need to rethink your logic or do a first comparison, then if it ends to Default, do a second one.

@dreamy basin you need to use a Timer to wait for 30 seconds, then you can use a timeline to animate your gate opening. There are other ways of course, but this one is pretty straightforward.

@desert rovernot sure there is a general answer to that. Typically you would use a thumbstick axis to control the aiming angle. This can be easily done by mapping the axis input [-1,1] to your angle, say [-45,45], simply by multiplying it by the angle absolute value: Axis Value * Angle Absolute Value

[warped spindle]

Does anyone know why my location of the block volume changes just when i play the game in standalone and mobile preview? When i'm in viewport it's working just fine

[onyx pawn]

I have a compass that gets facing of player controler on map but I am wondering how can I also have the camera get diration of camera on level

[tropic olive]

Hi
How can I start my blueprints events in the sequencer?

[atomic salmon]

@warped spindleyou mean a blocking volume placed in the level? Its location should not change. How do you realize it has moved?

@onyx pawnnot really sure I understand what you are asking. Do you need to get the direction the camera is pointing to in world coordinates? That would be Camera --> Get Forward Vector.

[warped spindle]

When i play the game in viewport the block location it's ok,but in the standalone it's moved somehow closer to me. It's brick breaker game. The paddle should move left and right. From block volume left to block volume right. But in the standalone alone they are too close to paddle.
I hope you understand what I mean

[atomic salmon]

@warped spindlethat is strange because it shouldn't move around just because you are changing the way the game is played. Unless, of course, you change its position depending on the screensize or something along these lines. Do you?

[warped spindle]

Ohh.. so that must be... The screen size of the game is in portrait. 1280 x 640
So.. when i Play it in Viewport that screen size is automatic but in the standalone it opens a new window where I can modify the screen size

Thanks. My plan right now was to export it and test it on Android,maybe it doesn't have that problem anymore

[warped spindle]

Ok.. i check it. That's the problem. Do you know how to fix that?

[atomic salmon]

So it moves because the screen resolution changes? How do you position it in first place?

[warped spindle]

I worked in viewport so.. i made the position after that

Or after the camera

[safe iron]

Hey guys

I have a small question, probably something super easy, but I'm a beginner

I have made a simple weapon roster using an array, Child Actors and Child Actor Variables, it works fine, with the mouse wheel I can switch between the four weapons that are currently in the game, but I would like to make it so not every weapon is unlocked by default, I want to make it that some are unavailable until you pick them up, so, how do I make it in the character blueprint? and how do I make the pickup? Thanks in advance

I'll send my blueprints here, it's not all of them, if you need more tell me

This is the function I made

[atomic salmon]

@warped spindle I don't do much mobile development (only VR on Android), so it may be better to ask in #mobile . In general you want to do your placement as a percentage of the screen resolution (like it happens with UMG). You can also count on the fact that the target resolution is known and use it directly.

[fast blaze]

hi all, do you know why my animation montage is playing in world space, not in local space, when I rotate character mesh inside capsule or I need to rotate capsule too?
when mesh is rotated inside capsule, montage is still playing vertical
thanks

[warped spindle]

Hmm ok. Thank you very much.

[atomic salmon]

@safe iron either you pre-attach all the weapons but keep track of those that are equipped with an internal flag for each weapon (e.g. a bIsEquipped boolean) and then check it before making that weapon usable, or you attach the weapon only when it is picked up (AttachToActor or AttachToComponent) after which you can assume all the attached weapons are available.

[safe iron]

Ok, I'll see how to do that, I think I'll go for the first options, thanks a lot

[atomic salmon]

@safe ironthe second one is more typical of inventory systems with a high number of weapons. The first one is ok if you have very limited weapons and you know all of them upfront.

[safe iron]

I would like to do something like Doom or Unreal Tournament, where you can keep all the weapons if you find them

Thanks a lot for your advice

[unique wasp]

I have a Blueprint class that implements an interface, and another one that wants to receive an object that implements that interface. How do I pass the object that implements the interface? I'm using a cast now, which seems to work, but makes me feel like I'm doing things wrong?

[dreamy basin]

i used sequencer for the animation of the gate i need to knw how can i set a timer for the gate to open

[atomic salmon]

@dreamy basin like this: https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/Sequencer/HowTo/TriggeringSequences/

@unique wasp looks legit to me. In C++ (and therefore in Blueprints) an interface is just a class (with only pure virtual functions in it), so as long as your actor implements that interface it derives from the interface class so you can cast it to it. Not sure whether this could be useful, but you can use the ImplementsInterface node to check whether a certain class implements a given interface.

[gloomy walrus]

hey guys! how would you make it so that a widget (like a crosshair) follows the mouse position?

I'm having trouble with this and I figure this should be really easy lol

[willow breach]

anyone know a tutorial that shows how to make a seamless portal gun?

[atomic salmon]

@gloomy walrushttps://www.youtube.com/watch?v=Hb31pUMFphg

[dreamy basin]

nw how can i put a 30 sec timer after that 30 sec the gate will automatically opes like we see in shooter games preparation phase

[atomic salmon]

you know what, since you are using Sequencer anyway, I would just play the sequence on Begin Play. Inside your sequence, place a keyframe at 0 and at 30 seconds, leaving the angle of your gate unchanged, then animate the angle from second 30 on. In this way you spare the Timer.

@willow breachdid you google it? https://www.youtube.com/watch?v=v3paFpIilGg

[willow breach]

yes that one works, but isnt seamless like the actual portal game

i am currently using that one

[atomic salmon]

@willow breachthen you need to merge it with something like this: https://www.froyok.fr/blog/2019-03-creating-seamless-portals-in-unreal-engine-4/

[willow breach]

yes cuz i know how to do thay

that*

[tropic olive]

Hi
I made a turret blueprint which is shooting continuously. My question is how can I activate it in the sequencer? (So I would be able to control when it shoots in my cinematic.)

[atomic salmon]

@tropic oliveyou can define a boolean variable inside your turret BP, make so that it fires only when that variable is true, then expose it to cinematics and change its value from sequencer.

[azure sparrow]

oof ok

[candid nest]

@everyone hey i want to make a system in whcih when i pick something i can kill enemy but for the time till i have that ability somewhat like pacman

[gloomy walrus]

duh, was getting around it the "hard" way. Thanks a lot Marco, that solved it!

[atomic salmon]

@candid nest you need to use a Timer for that. You set the Timer and at the same time give your pawn the power to kill (by setting a boolean variable to true). Once the timer has elapsed, you remove the power by setting the boolean to false.

[candid nest]

okay i get it but how to make him kill

[atomic salmon]

@candid nest this is not a question that can be answered in one line or so. The short answer is that you apply damage to your enemies (either by shooting them or touching them or in some other ways) and once they have received enough damage they will die (which typically means you delete them from the level).

[unique wasp]

Okay, clear! Thanks! :)

[candid nest]

yes exactly this thing i needed thanks man thanks aloy

a lot*

[languid lion]

Is there a way to blend view target to another camera and not be affected by global time dilation?

[atomic salmon]

@candid nestyou can use a simple overlap events between your pawn and the enemy to apply damage, but only if in kill mode, otherwise you will receive damage from the enemies. There is a pacman tut on YouTube you may want to watch: https://www.youtube.com/watch?v=PluQO5fpyLA

[candid nest]

thanks man thkans a lot i need this only

[trim matrix]

Does any one know how can I prevent camera from going up once I start jumping in ALS? Actually whole capsule goes up and I can`t find where it happens.

[indigo bough]

Has anyone successfully modified the water wave generator values at runtime? Thought I was onto something with my current setup, but I'm not seeing any visual change, even though the values are changing in the WaterBodyOcean actor.

[indigo bough]

I also noticed there is a "Simple" and "Spectrum" asset type for this input, but I cannot seem to find a way to use Spectrum, just wondering what that might mean/allow that 'Simple' doesn't.

[void needle]

how can i teleport my player towards location he is facing?

[zealous moth]

Get forward vector and then get the location of that multiplied by the distance

@trim matrix what i did for als is make my own camera and disabled theirs.

@languid lion use relative dilation and put the difference

[trim matrix]

this is an option, but there is another custom logic already binded to this cam

[zealous moth]

Unfortunately als systems are not components they are tightly woven and very difficult to work with

[trim matrix]

the issue is actually not in camera, since its just follow the capsule. I cant find where and what controls the capsule.

[zealous moth]

Check the als parent

[trim matrix]

Once I press space it fires up Jump start at BP_BasePlayerController. Then it goes to ALS_Bbase character. And there is a function jump. But I cant open it or edit this func

[zealous moth]

That would be the base jump function iirc

[trim matrix]

so that mean that capsule position is set somewhere else. But find reference gives noting useful

[languid lion]

But on what exactly? Player character? I've tried it on the camera actor but it makes no difference

I'll give it a try with offsetting custom dilation on the player character

[zealous moth]

Let's say you want to stop time for all except the player. You set a global time dilation to 0 while you set your player's back to 1 using custom dilation. It would be on the actor itself.
Based on what you say, it sounds like you use a separate camera? Set that dilation also to 1.

Fyi, you can blend between cameras without having to maintain the same actor

[void needle]

i didnt quite understood what you meant, i tried but it still doesnt work

[zealous moth]

your pawn will have a forward vector. I don't recall if normalized or not. Whichever, you can then multiply that vector by a float for a distance and then get the location. Then teleport

[sand shore]

direction vectors from the API will be normalized (because otherwise they're offsets and not directions)

[void needle]

ty, already done

[fossil skiff]

anyone know how to do ue4 hit based reactions?

[atomic salmon]

From the On Hit Event

[fossil skiff]

im no advanced level ue4 user so ur gonna have to be a lil more specific

[atomic salmon]

When your player hits something or something hits your player, the engine triggers an On Hit Event. That event contains all the information you need to react to the hit, for example by applying damage to your player or to an enemy.

[fossil skiff]

Ahhh

[atomic salmon]

For the On Hit Event to be generated some conditions have to be met, mostly ensuring your colliding actors have a collision volume around them and that they are set to collide (aka block each other).

[rain egret]

a quick question, in coding you can set a class to final so you cant create instances of that class, how does this work in ue4?

i have a parent class that i want to forbid being created by accident

[maiden wadi]

@rain egretI could be mistaken, but I don't believe you can do that in Blueprint. You could likely do that in C++, and also mark the class as Not Blueprintable, but that would just keep you from creating blueprints of the class.

[rain egret]

hm, alright thanks

how can i damage children

i have child actor components with health that are basically modules that will affect the performance of the actor. how can i damage those?

i have tried radial damage and also the hurt zone. but it doesnt seem to register taking any damage

[maiden wadi]

Unsure. I generally avoid ChildActorComponents. But my initial assumption would be to make sure you're calling it on the right thing. You can get the actual actor by calling GetChildActor on the child actor component.

[worthy tendon]

Hi, Is there a way to trigger a sound inside a sound cue multiple times using sound cue parameters?

[rain egret]

what alternative could i use then? all i need is an object that runs an event when damaged

i have a HUD element that portraits the amount of damage each module takes

the modules are placed in her limbs so when something near her stomach explodes it should damage the modules placed there

theres a blueprint with the sole purpose of testing the damage system. i can only damage the child when i address it directly

[safe iron]

Guys please help

I made this weapon system meant for an Unreal Tournament like game, where you can hold something like 10 weapons at once and switch between them if you unlocked them, and here comes the problem, I have no idea on how to make weapon pickups and an unlocking system for those weapons, I have searched the internet for hours and I have found nothing, it's almost like I'm the first guy who has ever tried to do something like this in Unreal Engine 4

I am a beginner, I mean an extreme beginner so, if possible, I would ask for images of code so I can write it instead of a message that says "Use this with that" and stuff, that just leaves me with more questions than before

this is part of the code I wrote for the weapon roster system, there's a lot more code I wrote on this and if it's necessary just tell me

[heady burrow]

The problem is that you don't really have a problem. What you are asking is no much different from: "hey guys, how can I make a game?"

Advice: watch some videos, lessons on how to do basic stuff.

eventually you will connect the dots and make your game

and when you have concrete questions, you can come here and ask

[safe iron]

Yeah you're probably right

Thanks

Tomorrow I'll start a new project from scratch and follow Unreal Engine's tutorials, then I'll move on, thanks

[twin ore]

Hi guys! I'm attempting to put my own spin on Stardew Valley's fishing minigame. My goal is to make it so the slider starts in the middle while the fire above and below alternate randomly so the player needs to "balance / guide" the slider between the flames. I'm not entirely sure where to start; I've attempted to find some documentation online, but thus far my Google-fu has failed me. I'd appreciate some assistance, no programming has been done at this point.

[echo wave]

Hey all! Does anyone knows if it's possible to Run a Editor Utility Blueprint, from an Editor Utility Widget? Like, with a press of a button in my Editor Utility Widget, I'm calling to Run a Editor Utility Blueprint.

[quasi relic]

Hi everyone. How do I calculate the end point of a linetrace so that it reaches the location of an actor? Like this:

[jaunty dome]

is it possible to have camera and spring arm inside of Player Controller instead of Pawn ?

this is how far I've gotten, I want the camera to be fixed and the player pawn to move inside it, what I'm doing now is adding local offset to player mesh, however its not working properly (collisions and everything)

if I move the player pawn the camera will move as well

[gentle urchin]

Viewtarget as a custom camera pawn moving at fixed speed ?

Or moving the spring arm to root instead of collision volume

So that you can offset the collision volume aswell

[jaunty dome]

you can't set spring arm as root in Character as it inherits Collision Capsule as root

but I like the first solution

[gentle urchin]

Adding a second spring arm would work aswell i think :p ignoring the inherited one

But ye custom pawn gives more options i think

[quasi relic]

Got it working, thank you!

[jaunty dome]

trying to create a custom pawn however add movement input doesnt work

[atomic salmon]

Add Movement Input requires a movement component to be part of the pawn and should target it

[gentle urchin]

Its gonna be moving at a constant speed, so cant you just add world offset on tick?

[hybrid latch]

Anyone who has a pointer about the best way to handle gunshot hit location on the player mesh? I would like to implement a more detailed damage system depending on where the player or AI got hit.

[gentle urchin]

Think you can get hit bone

[marble nova]

I have set up a dialogue system using data tables - i want one line to tell the player how much time they have left based off a variable owned by the gamemode - is it possible to reference variables from data table to include in the dialog?

[hybrid latch]

Will hit bone register if hit is on the connected mesh?

[quasi relic]

Is it possible to rotate a linetrace to an actor?

[maiden wadi]

@quasi relic What do you mean by rotate the line trace?

A line trace is a query from point A to point B

[quasi relic]

Sort of like this, the red line would be like a bullet

[maiden wadi]

The black square is the start, and the circle is the target?

[grave swan]

If i shove a group of objects into a folder in my level outlined, can i access the contents of that folder specifically in the level blueprint?

[quasi relic]

Yes the black square is the origin and the circle is the target in this case

[maiden wadi]

What do you need rotated exactly? You have a start and end point.

[quasi relic]

If I use the target as the end point, how do I clamp the line trace? I want the lines to have a range

[maiden wadi]

(Target-Start).Normalize * MaxDistance

Or, TargetVector minus StartVector. This converts it to a local space length vector. Then you normalize it so that it's at a length of 1.0. Then you multiply it by your max distance to extend the new end point to that location. You use that newly found end point as the end of the trace. Same start point.

Er

Why do I always forget that?

After the multiplication, add the Start point to the newly found end point, THEN use it as the new end point of the trace.

[woven arrow]

quick problem: my enemies can't seem to detect my player in an AIMove To node, no matter what I try to change. I already have it set it for the ai to auto possess after being placed in the world or spawned in, but now it just doesnt want to work.

[quasi relic]

PERFECT! Thank you so much o7

[grave swan]

Is ur navmesh setup?

[woven arrow]

Yep, the volume is in there

It was working perfectly fine before, but then I was working on a main menu and adding a button to start the game proper, and then when I did, thats when the AI went bust. Not sure if that has anything to do with it, tho.

nevermind, i just deleted the old navmesh, put in a new one and it works fine

[heady zenith]

I have a problem, When I open a level and then come back to the last level, it didn't get reseted

I mean: In the first level I get this droplets and they dissapear, then I change to my second level with "Open Level" and from that level I come back to the first, again with "Open Level" but the droplets still destroyed, I need to do something special to open a level and reseting it to it's default state?

[trim matrix]

hello

does anyone know how to make a playsoundatlocation node with a referenced AmbientSound in the level?

this is the reference

I want the user to be able to walk around the vehicle and hear the sound dynamically

which is why I need it at the location on the scene

[fast lintel]

guys i need help

whenever i equip weapon an unequip

the weapon appears everytime mor into the character`s chest

till it ends up in the head

[atomic salmon]

Looks like your weapon is getting an offset added to it each time it is attached. How do you attach it and detach it?

[fast lintel]

do you want a pic of my blueprint? or rather watch the tutorial video i copyed

he triggers an event with left and right click..

but i used just R to sheath and unsheath

[atomic salmon]

No time to watch tutorials sorry

[fast lintel]

checked the R event with a branch

made a copy one true another false

so when i have a weapon in back an press R

i grab it

but if i have no weapon in back and i press R then i put it on the back socket

i have a weapon interface

created

the weapon its an actor

inside that actor i made the attach blueprints

[atomic salmon]

When you attach it do you add any offset?

[fast lintel]

im not sure

i only set it so that when i pick up it goes to back

then with R i equip and unequip

from spine socket

to hand_r

[atomic salmon]

Can you show the attachment code

[fast lintel]

yes just a sex

sec

[atomic salmon]

You are probably keeping a relative offset

Instead of snapping to the socket

[fast lintel]

thats in the player event graph, i do the R key event with the anim montages

and under that i have this

draw axe to AxeHandR socket and to sheath, its the backaxesocket

[atomic salmon]

Can you change the Location Rule to Snap to Target

[fast lintel]

yes

lets see

from both?

still dont work

[atomic salmon]

Yes. That ensure the weapon gets centered to the socket

[fast lintel]

its like every time charac grabs it

leaves it in a different position

nevermind fixed it

and thanks to you lol

thanks a lot

[atomic salmon]

So what was it?

[fast lintel]

i did change the snap to target

not only in location

but also rotation

also, do you know how to lock the crouch?

i have set up the basic crouch uncrouch

put it crouches as long as i have the C key pressed

[trim matrix]

So I managed to get the sound I wanted inside a blueprint

but for some reason the sound starts as soon as the level starts instead of waiting for the blueprint to be activated and called
