[hazy flax]

hi guys can any one know how can i get this node in bp?

[main lake]

Get your variable > Right click on it > Convert to Validated Get

[hazy flax]

i can't find

[main lake]

No, get it first in the graph

[hazy flax]

ok got it

thx dude

@main lake

Anyone please ☝️ ?

[keen widget]

How to get x y size of the downloaded image ?

[silent stag]

i am confused man maybe i should watch the that tutorial first

[thin panther]

Youve used the set node but not set it to anything

Id reccomend following some resources like the blueprint communication video pinned here, and some of the starter resources in #ue5-general

[dark drum]

What's the value before you ceil? I can see you have a print for both.

[dark drum]

I would imagine get size.

[main lake]

9.5

[keen widget]

no

[dark drum]

As ACuppaTea has said, you need to learn more about blueprint communication. For a quest system, you'll need a good understanding of event dispatchers. If your not using them, you'll run into a lot of issues and things will get messy very quickly.

[dark drum]

When you pull from the 2d texture ref (I assume that's what it is) and you search for get size what options does it give you?

[main lake]

Wait, it prints 9.5 before the ceil, and 10 after the ceil, which means that's correct, that means something is wrong with the rest of my logic 🤔

[main lake]

somehow it generates 12 hearts instead of 10 🤔

[dark drum]

That seems right. 19/2 is 9.5 which ceiled would be 10.

[main lake]

Yeah but why it adds 12 hearts to my horizontal box 🤔 ?

[dark drum]

I don't know, you haven't shown how you add the hearts.

[dark drum]

Oh it's a dynamic 2d texture. I don't think the get size nodes for dynamic textures are exposed in BP.

[dark drum]

You'll need to minus one from the last index if the start is 0 or you'll get 1 more than you want. I'm not sure why you get two more though.

[main lake]

Did that, somehow it's all fixed now 🤷‍♂️

thanks 👍

[lunar sleet]

Aye def do that

[velvet pendant]

Hey! I have a question

In my Bullet_01Basic I do have the event HIT
i made the Print debug to see if it’s recognize only the enemy [the bullet]

I have 5 ChildBlueprints from AI_ENEMY. wich spawns random
The question is: How do i get ENEMY_HEALTH from every child, [they have different HP] And apply damage to it. Also, how Apply point damage works? the base Damage?

I wanna create a Top down Shooter btw. Ty!

Long short exp:

Event hit > Cast to AI_ENEMY > AS AI_ENEMY > GET MAX_HP .
Event hit > Cast to AI_HUNTER > AS AI_HUNTER > GET MAX_HP .

How do i cast to every AI child [ ENEMY IS THE ,MOTHER"] To get the MAX_HP, so i can substract the damage my player have SMTH like

Event hit > CAST TO ALL ACTOR OF CLASS > GET MAX_HP > SUBSTRACT DMG_PLAYER - MAX_HP .

can’t get it to work, any ideeas?

Srry for the long message.

I'm not home so i can't show photos

[keen widget]

maybe i can convert it to something that allow me to get it size?
my problem is that after image was downloaded i want to change my image according to its size to fix stretching

[thin panther]

why do you want to hit every single class of that type when you hit one of them?

That's not how bullets should work

[dark drum]

Isn't there an option on the slate brush to do that?

[velvet pendant]

i don't i just want to get the variable of GET Enemy_HP from the actor i hited.

That's the only way i know so far.

[thin panther]

so why do you want to cast to everything?

[dark drum]

You could create an actor component for managing stats such as health. When the bullet hits an actor, you can use the get component by class and get the stats component from the hit actor.

[thin panther]

alternatively just make your ai share a base class that has health implemented

they should anyway

i'm just confused why you want all actors of that class

[velvet pendant]

That's how i used till now to substract the HP, from enemy with, cast and substract, dunno i'm still learning some things

[velvet pendant]

That's an ideea

ty

[dark drum]

With you still learning, all I can say is everything has a manager, even the managers have managers and those managers have managers. 😛

[lime zephyr]

Why isn't this in UE5

[main lake]

Is it possible through blueprint to modify the "Image (Brush)" property of an image inside a Widget BP ?

[dark drum]

Yea, there's a few ways you can do it.

[main lake]

How please ? I think there's this node to do that but how do you make it understand that the created widget should switch its image to the on ein the SlateBrush ?

[dark drum]

If you just need to update the image, you can use the set brush from image.

[main lake]

can't find that node

[dark drum]

Sorry, set brush from texture.

[lime zephyr]

I disabled this thing, and I still can't find the setting in the blueprints

[dark drum]

From the forum post, you would need to use a console command to change the screen percentage in UE5 by blueprints. You can call console commands using blueprints.

[dry sleet]

Dunno if you got an answer, but one common way BP corruption manifests itself is if the details panel of a component is blank when selected in the BP editor.

[blissful summit]

yeah.. thats how i concluded it being corrupted after seeing the bugged out lights

[blissful summit]

but my question exactly is how can i identify the corruption without needing to click through and find out through the details panel

otherwise there are cases where i can see it going unnoticed for multiple iterations

[dry sleet]

I don't believe there is a built-in system for it.

[dark drum]

How would a program know another program is corrupt if it doesn't cause a crash? I don't think it would be possible to actually know unless it crashes.

[manic summit]

noted, thank you 🙂

[keen widget]

sure but first i need to GET its size somehow...

[dark drum]

This node is probally what you're after.

[keen widget]

maybe this can help, thanks!

[remote meteor]

download image returns dynamic texture?

[edgy ingot]

Cast to texture2d and get size x and sixe y maybe

[remote meteor]

theres both i guess its ok

[keen widget]

hm, ill try them, maybe this nodes can work

[trim matrix]

i am trying to open this drawer but i can't manage to make it follow the arrow, also there are some collision problems when i deactivated collisions with pawns

[dark drum]

Not entirely sure of the issue but I'm surprised you don't get an infinite loop with that retriggerable delay.

[trim matrix]

no actually it's the only way i can make a loop

i use it everytime i need something like that

not entirely sure how performance will be affected

[dark drum]

Swap it out for delay until next tick. Small timers aren't great, especially when it's 0.

[trim matrix]

something like this?

[dark drum]

Yea.

[trim matrix]

well thanks, it works

[dark drum]

Has that fixed the issue with it not sliding in the right direction?

[trim matrix]

no, i said it works because it acts like before

but it didn't fix the issue

[dark drum]

Instead of getting the forward vector of the rotation of the arrow, try getting the forward vector of the arrow itself.

[trim matrix]

i need the relative coords of the arrow because if i take just the forward vector the drawer teleports away

btw the most that i can do is this, where the drawer moves on the x axys based off the camera

[versed sun]

https://tenor.com/view/i-see-no-problem-here-no-problem-crossed-eyes-dont-worry-gif-16343187

[dark drum]

Store the initial grab point and then subtract it from the handles current location, multiply by the forward vector of the arrow. Add this back onto the initial grab location to get the new location for the handle. (hopefully that makes sense)

[trim matrix]

i'll try to do it

[keen widget]

thats good, but i still cant understand what to do with it
i tried this but didnt helped

[dark drum]

What happens if you just call the set brush from dynamic texture?

[keen widget]

call the set brush from dynamic texture?

[dark drum]

I've just realised you've not got it hooked up to 'OnSuccess'

[keen widget]

oh yes, i forgot to recconect it,but it doesnt matter its not fixing it

[dark drum]

What happens? (if anything)

[trim matrix]

well, english is not my first language so undertanding that wasn't simple, but i came up with this and the drawer teleports away

[keen widget]

right now its just switch img with new streach one that it downloaded

only way around it i can see that you must force user to look at original img with and height and then set it by hand
before or after u downloaded img
but its really not ideal way to do this 😖

[dark drum]

Something like this.

[dark drum]

What happens if you do this?

[blissful summit]

yeah true

[keen widget]

still streched

[dark drum]

Are you sure the image it's downloading isn't stretched? What if you try with a different image? (One that's smaller)

[keen widget]

https://i.imgur.com/GSPuXxO.png original

[dark drum]

Is the image component itself set to fill horizontially or vertically?

[distant hollow]

Check the picture size and your icon size

[keen widget]

SIZE TO CONTENT WORKED!! YEY! im happy

[keen widget]

nice, its really good as first step, really happy i fixed this, thank you!

[spice viper]

Cool map btw!

[keen widget]

not mine, its just for test 😄

[trim matrix]

sorry if i am asking too much, but where do i set the inital location? i have done this and my drawer isn's moving

[dark drum]

hmmm, that looks right. Print the vector length of where you get the location and minus the initial grab point. It should give you the distance from the starting point. Does this length change at all? if so, what sort of values is it giving?

[trim matrix]

ok so i tried printing some values and the blue one is forward vector from the arrow and the yellow one is the final location for the set target loop

one last print i tried is the grab point variable and it prints the same of the yellow after it stabilizes

didn't think a drawer would be so complicated

[dark drum]

You need to print this bit. Pull from it and get vector length and print the returned float value.

[trim matrix]

ok so this prints this...

just zero

Hi!

Sorry, it has a lot of details to put it here.

Thanks.

[warm pulsar]

Hey, I am trying to run some tests, I have an actor that moves in a circle. hence the x axis value has a HighestXValue and a LowestXValue. I am trying to store these values in an float array (ArrayXValues) and I use a for each loop to iterate through the values comparing them to get the highest and lowest.

My issue is
I try add these values to the array. But when I add a break point to view all the values in the array to manual check I am getting the right value, the array only has 1 index value.

So how do I add a value to a new index of an array?

[dawn gazelle]

Why an array? This seems like you only really care about two distinct values.
If you want to use an array to store these two values, you can always use the "Set Array Elem" node, and modify the speciifc index of the values, so like use index 0 for the lowest value and index 1 for the highest.

[lethal pollen]

There is a blueprint class in the VR Template which inherits from Skeletal Mesh Component with a Materials group. I have created a custom blueprint class which also inherits from Skeletal Mesh Component, but it doesn't have the Materials group. Where does the Materials group come from?

[dawn gazelle]

Add your skeletal mesh, then the materials slots that are available will appear.

Hi everyone.

I am attempting to make my own game using blueprint.

I am wondering if I can find anyone that can help me on my journey by looking over my work and giving feedback and suggestions.

I’m nervous that I will make a big mess and am trying to address problems as I go before they get to be too big.

I sadly do not have any money to pay so I wonder if I could find somebody who can do a trade with me. In exchange I am able to help with what I’m good at - 12 years of experience with 3D animation, modelling, rigging, etc. I can cover the entire 3D pipeline.

If anyone has the skills in blueprint and is seeking help with 3D graphics please send me a DM!

[dawn gazelle]

You're better off looking over #instructions and posting a job offer (as a volunteer project) than asking in this channel for support like this as it'll just get buried. If you have specific questions or need help with a specific problem, you can post your stuff here and there's many of us here who are willing to assist.

[hollow cove]

what am i missing, why does it work when i move a slider but not from the game instance?

[fleet cedar]

Will do thanks

[hollow cove]

[brisk rain]

Hey! I wanna know how to call a function from a different blueprint. Thanks!

[hollow cove]

you need a reference to the blueprint or use interfaces

if you're spawning that blueprint with the first blueprint then you can pass the value across

[surreal peak]

For Interfaces you still need the Reference...

Also Interfaces are not a solution to "How to get the Ref"

[brisk rain]

that sounds complicated...

[hollow cove]

what are you trying to get a reference to

where is the function located

[brisk rain]

well i want a widget blueprint to do a function when a third person character calls it

[surreal peak]

Check the pinned messages, there is a video, while rather oldish stil lrelevant, that talks about this

[strong turtle]

Hey, anyone know if it is possible to make the actors placed in the editor that overlap eachother initially fire off the onbeginoverlap? Only seems to fire it off when beginning overlap that isnt initial from the actor placement

[dim agate]

Maybe have it initially trigger from the event begin play node and then subsequent times you want your BP to fire have it triggered by later overlap events?

[strong turtle]

Yeah i just used GetOverlappingActors on beginplay

[remote meteor]

if you want to reuse the overlap event, you can re-set your collision size during begin play, and make sure to update overlaps

[brave rain]

Hello guys, I made a settings menu but when I try to change graphic settings I don’t see any differences. Screen mode and shadow quality settings work well. How can I fix that? The engine scalability settings menu doesn't change anything either

[remote meteor]

double check your outputlog if there is anything that says, skipped setting scalability due to some higher level command, i forgot how it is exactly phrased

[dawn gazelle]

Everything in the engine can be considered an "Object".
An "Actor" is a type of object that exists within the game world and has a transform.
A "Widget" is a different type of object, one that is meant to display UI, it doesn't have a transform.
Widgets do not inherit from Actor, so you can't expect to get an "Actor" reference and cast it to a Widget.
By using "Get Actor of Class" and using "Actor" as the class you want to get, you're basically saying "Find the first actor in the world" regardless of what actor it actually is, so this isn't really what you're wanting to do.

To get you going, though not necessarily the best solution, use "Get Widget of Class" and specify the class of the widget you want to get. So long as there is only 1 in existence in your game at the time you're calling it, it'll retrieve that particular instance of the widget. You wouldn't need to cast or anything, you should just be able to call your funciton from the return value.

[fast finch]

I have a strange issue. I have a flying pawn, like a jet. When i fly straight towards an object in the ditance, the movement direction suddenly tilts abit. Meaning i miss the target i was looking at by at least 100 meters and more

its really obvious too

i checked the rotations and everything

the forwards are the same continuesly

there is no change

[brave rain]

That's all what I get, when changing something in scalability menu

[fast finch]

[willow cedar]

In Blueprint, what would be the most efficient way to find the nearest Line Trace Collision?

I'm not sure if I should just do a ton of Line Traces from my Character in random directions, then pick the two closest or not.

I'm not sure how expensive that would be.

[dawn gazelle]

This sounds like you could probably just do a sphere trace. What is it that you're actually trying to do?

[brisk rain]

Hey! Sorry I'm late, but thx for the help, I had to use get all widgets of class and a for each loop tho because i couldn't find any "get widget of class"

[willow cedar]

I have a right click ability to grapple in the direction your camera is facing, and I want to find two points slightly angled from center crosshair to grab onto. This is only for Visual Purpose, and I need it to find another point if there isn't anything there.

Here are two examples I drew over to show what I'm trying to do.

Ideally, if you were looking straight up at the sky, I still want these lines to find a surface below or nearby

Actually, I'm guessing Sphere Trace is a Sphere I can choose the size of to shoot out, meaning that would work really well

I wasn't familiar with it's use case, but I can see how that works here

[brisk rain]

quick question, any way to add multiple texts in 1 widget blueprint or join 2 variables with a newline?

[dawn gazelle]

There is "Append" which allows you to join strings, or you could use "Format Text" which allows you to define {variables} in the format field and then provides with inputs for those variables.

If you want to add a new line, you may need to hit shift + enter into one of the fields.

[brisk rain]

oh alright

i was trying to use \n lol

tysm

[wraith loom]

I made a blueprint class with "Object" parent, but code doesn't run on it. Do I need to somehow spawn the Object in the level in order for the code to work? If so, how? Because right now it's just sitting in my content drawer.

[spark steppe]

construct object

and then keep a reference around of it, as it would be garbage collected otherwise

[earnest vigil]

Anyone have any idea how to get the velocity of the world itself not just for a specific actor?

[spark steppe]

the world doesn't have a velocity

unless you mean the gravital force?

[kind estuary]

I find myself doing this function from scratch in every single project:

Is there this function already in the engine and im missing it?

It seems to me something that unreal should have

It needs to loop through the units and check who is the closest

thats it

there should be something that at least gets the closest vector from a group of vectors to a vector

[dawn gazelle]

Create yourself a plugin that contains a function library that has your commonly repeated functions.

[arctic elm]

Hello.
I am trying to bind an action to a key press to push a debugging menu over the current widget (its a common activable widget)
However, it doesn't do anything. (edit : the widget doesn't respond to input at all)
what could I be doing wrong?

[spice viper]

Not sure how this node works, but does it automatically add it to the viewport ?

[arctic elm]

no.. the problem is that the widget doesn't respond to the input at all.
I just realized that

[spice viper]

Ah, if the Event Graph is from a widget, I don't think key binding occur there like they do for pawns. Try overriding the OnKeyDown/Press functions?

[lofty rapids]

why is your key input in your widget ? why not create the widget and have a reference so you can call it like normal. I think keys are usually in the player controller or pawn

is self the widget ?

[arctic elm]

I just want a hidden debug menu to appear when a certain key is pressed.
I am trying to find the most simple solution.
OnKeyDown might just work, I am trying that right now.

[lofty rapids]

or is there a reason for get owning player ?

[distant hollow]

Like engage said, just put the key on your Controller or Pawn instead

You can create the widget at start and hide it, then on the key just set the debug menu visible

That would probably be like the simplest

[arctic elm]

thanks for the suggestions everyone.
I tried @spice viper 's suggestion to override OnKeyDown and it worked like a charm. Additionally I had to set the widget to be 'Is Focusable' to make it work.

[kind estuary]

I dont understand well the difference between Text and String.
In my searches, it says Name is better for text that you will not change, like a ids, names, etc...
Whereas String is for text that you need to change and alter at anytime.
So where does text compare to string then? And why would i use text over string?

[arctic elm]

From UE Docs (https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/StringHandling/) :

FName - FNames provide a very lightweight system for using strings, where a given string is stored only once in a data table, even if it is reused.

FText - the primary component for text localization is the FText class. All user-facing text should use this class, as it supports text localization by providing the following features:

FString - Unlike FName and FText, **FString **can be searched, modified, and compared against other strings. However, these manipulations can make FStrings more expensive than the immutable string classes.

[kind estuary]

So basically FText only makes sense when used in the UI?

[arctic elm]

personally I use FNames for identifying objects, FString for debugging but I am sure there are better use cases and FText for UI

[arctic elm]

I believe so

[kind estuary]

thanks @arctic elm

[empty gust]

i do not understand why my widget animations are not working on overlap events

[dim agate]

Apologies for posting this again but have tried many things to try and fix this camera issue and basically have run out of ideas. All I know is it's caused by setting the z value in the "Set Control Rotation" node during the camera transition. As far as I can tell the camera should be returning to the exact same transform every time yet it doesn't, it bumps sideways as shown.

https://gyazo.com/3cb8ec0fed7e84093d5fc6e7cedba559

https://blueprintue.com/blueprint/jv_q5-8_/

[willow tendon]

so i need to loop through an array of actors, get a bool from each, and ONLY do something if all bools are false... how do you do that?

[lunar sleet]

It’s too hard to read blueprintUE on mobile but debug and watch the values that are coming through so you can see what exactly happens

[dim agate]

There's a way to print the transform for the camera throughout the BP?

[willow tendon]

are you using set view target with blend? or are you lerping it

[dim agate]

Lerp.

[dim agate]

Actually I think I know how to do that, still would leave me with the mystery of why it doesn't return to the transform it's supposed to.

[willow tendon]

reminds me of a problem i had when useing "lookat tracking" settings on a camera

[lunar sleet]

🤔 you could maybe add 1 to an int each time that bool is true and then if the int == the length of the array, give ‘er

[willow tendon]

wouldnt track during the lerp

[lunar sleet]

Print or watch value to see if the return xform is actually correct

[dim agate]

After testing it a lot I narrowed it down to this value here causing it.

[willow tendon]

have you tried using view target with blend?

might clean that up a bit

plus has nice easing options

[dim agate]

No, I did hear about that a while back but I had the impression it was for static cameras.

[willow tendon]

nah, its great for a lot of cases

i'd go down that route

[dim agate]

Would this just address the jerkiness of the bump? Because the actual transform not being what I want at the end of the transition is what causes issues going forward with other things I want to do with the camera.

[willow tendon]

yeah it would

jsut blend between first person anf thrid person cams

half that bp would be a single node.

[dim agate]

I mean I am fairly certain the transform is simply not correct at the end judging by how the grid on the floor is aligned with the edge of the viewport, how the angle alters more and more after each transition.

[willow tendon]

honestly, i'd refactor that with Set View Target with Blend

[dim agate]

I'll give that a go for sure.

[lunar sleet]

Always a good idea to actually debug rather than making assumptions but power to you

You might even find out why the issue is happening in the process.

[willow tendon]

the sass

love it

[dim agate]

It's not an assumption, I get printing the value is more certain but I can see the camera does not return to its original position quite clearly.

[willow tendon]

yo, save yourself an hour and just use set view target

[lunar sleet]

If the xform you gave it is correct, perhaps your timeline track has a problem or you have some collision issue

[dim agate]

It returns to the transform of a component that occupies the exact same transform with it at all times, that's why I find the whole thing weird (both components stuck on the same spring arm etc).

[lunar sleet]

Maybe they are colliding then?

[dim agate]

That was one thing I considered but can two cameras even collide?

[lunar sleet]

Yes

[dim agate]

Granted it doesn't return to the placeholder camera, I changed the component for a transform reference in to an arrow but the problem existed before that.

Where do collision settings exist for cameras? When I looked the other day I couldn't see anything.

[willow tendon]

this works, but i just would have thought there was a more graceful way to do this

if it works it works

thanks dude

Set View Target seems to not work with actor components. Doesn't accept them as targets. Is what you suggested not supposed to be implemented in the player character BP?

[willow tendon]

wdym, use the player controller and get the camera component

actor > get camera component

its cannonical like that

[dim agate]

This is within the character BP or the player controller BP?

[willow tendon]

wherever your camea is, charachter i'd presume

[dim agate]

I don't understand what you mean by getting the camera component then, in this context, there's nowhere I can see that accepts it.

[rough warren]

Just wondering what yall's process when gathering user input for display like on an interaction button or something.
I'm working on a proximity button where you walk near it, it shows a wdiget saying Press [InteractionKey] to interact but I actually want to fill that with what the key is. So not hard coding it to be E or something. I'm currently making use of the new enhanced input system and have a Interact input action and not sure how id' get the key value

[lunar brook]

Anyone have a pointer to how to hook into the "stop" or "pause" event for a Level Sequence Player in blueprints? I tried binding the On Stop and On Pause events but they don't seem to fire.

Also, I can't believe I somehow never joined this discord, probably could have saved hours of stupidly wasted time !

[fiery tiger]

My savegame keeps incrementing every time I activate PIE. Does this have an effect on the save data itself or is it safe to ignore?

I imagine every time the a new instance is created it just references the data from the previous one if it was saved. Just seemed strange to me.

[hardy merlin]

Hello. I have a sphere volume that I use to detect if they have overlapped a pawn. Now I am making projectiles and want to detect if the sphere hit a solid obstacle. Can I use the same volume to do so or do I need a second volume with different configuration to bind?

[kind estuary]

is there a way to set the default value of a variable?

there seems to be for custome primitive only

[hardy merlin]

You should be able to use the Details panel.

[celest pilot]

I need a little push in the back, I've done vehicles before but I'm stuck on an idea.

I want to make a mech that is not a Pawn/Character but a "Vehicle/Actor" so not using the Character Movement because of some reasons but I have no idea how I'd make it move forward/backwards/sideways (input only, rest I can figure out)

[hardy merlin]

Anything that has to do with input needs to be a Pawn.

Pawn does not need to be a Character, however.

The alternative is to make a special Input Mode that your character reads and sends commands to whatever vehicle they are part of.

[frail onyx]

does anyone know how i can make this go back to the start position smoothly without having to jump straight to it when i let go of my key?

[dawn gazelle]

You can change the play rate and use the "Reverse" input.

[frail onyx]

is there a way to make it stop looping when it reverses?

i tried making the release key go straight into reverse but it just loops forever in reverse

[candid sentinel]

Ok so I'm setting the mesh location in an actor to a point along a spline path. But if I set actor location, and the player ISNT MOVING, it just goes through their body. so i added a secondary static mesh of the same shape, and scaled it down to 99% the scale of the original mesh, and it still doesnt overlap unless im moving. kinda just at wits end atm. any suggestions?

[dawn gazelle]

So when you play forward, you'd want to set new looping true, on release, set new looping false.

[frail onyx]

ooo ok would i have that go in between the pressed and play? and the release and reverse?

[dawn gazelle]

yep

[frail onyx]

ok tysm for the help!

[candid sentinel]

i see people suggesting to make the mesh the root compoennt (this breaks a lot of things if i do that positioning wise with the spline, but even in doing this it still doesnt work)

[crystal crown]

Line trace against complex collision doesn't seem to work

[kind estuary]

sorry i didnt ask properly

i meant how to reset it back to the default value

that was set

so its 60. I change it to 10. Then need it to reset back to whatever it was

maybe need to create a second variable to store the original value, right?

[hardy merlin]

not sure if you can do this in pure BP, but you can get the class default object and get its variable.

[kind estuary]

that is awesome

[kind estuary]

thank you

[frail onyx]

anyone know how i can modify this so it plays while I'm currently moving around and then when i stop moving it stops

[robust mural]

is it possible to make asynchronous blueprint nodes which are executing commands in the gamethread ?

@frail onyx you need to get the value of the character speed from the character movement

[humble matrix]

My cast to actroll class fails, my set player is working i printed it, but not going any further than cast to actor class, any idea why ?

[frail onyx]

is there a way to activate it without using event tick?

[spice viper]

Add on tick (it's ok for very small things like getting speed), get character movement, get lateral velocity scale/size, set that to a bool IsMoving which also sets the timeline is looping.

[robust mural]

I would use it in the animation instance from the character

since its regarding to the players animation

[spice viper]

Yeah, do in the ABP

Ehhh maybe on the pawn, he's altering the mesh. Not the animations

[robust mural]

you could cast to the character from the animation blueprint

[spice viper]

Also true

[robust mural]

bump

[frail onyx]

wait would this world/be better than using event tick?

[leaden plaza]

would anyone happen to know a good base to start with for a system similar to wave function collapse

im not seeing any plugins that will do what i want to do

is there anyone that has messed with this that could give me some pointers

the system i would like to make needs to have each piece have some attachment points on it and each attachment point is assigned a number and only other attachment points with the same number can connect

or if someone could direct me to some videos or documentary that would be great

[hardy merlin]

Given an actor, how can I get its Player Controller, if any?

There's a "Get AI Controller" node but not one for PC

Found it, forgot I had to cast to Pawn.

How do you handle that kind of thing if the ASC is not on a pawn?

like if it's on a controller. Just check if owning actor is a controller?

[main lake]

Guys what's wrong with my Minecraft like "heart system" please ? The health variable is set to 2, the maxHealth set to 5. So the maxHealth is giving me 3 hearts slots, so that's good.

However Heart is set to 2 so it's supposed to give me 1 full heart only but somehow I have 2 hearts + 1 half heart.

[dreamy sierra]

How can make I make a static mesh component inside a blueprint change between being clickable and not clickable?

essentially block/unblock click on a specific object inside a blueprint?

[thin panther]

don't block the clicks, just ignore the click logic

[main lake]

You don't block the click, you rather create a variable inside that blueprint and set it to true when you want it to be clickable, and false when you don't want. And depending if it's set to true or not you do the action you want to do

[thin panther]

So have a boolean that prevents the execution going further.

[main lake]

Hey do you have a solution for my problem please ? 🙂 ☝️

[thin panther]

unfortunately your bp screenshot is a little too small to read :P

[main lake]

Fixed 😛

[hardy merlin]

What is your goal, exactly? 5 max health should resemble 3 hearts, the last one only half filled?

[main lake]

Yeah. 1 health = half a heart.

[hardy merlin]

You can do it with some math.

Number of hearts = Ceil(Max health / 2)

Half Heart = Max Health % 2

[thin panther]

I may be missing something but nowhere in that code are you using Health to fill in the hearts

which explains the 2.5 if your max health is 5

[main lake]

Where should I add that ?

[rapid lance]

Using the Health variable where you use MaxHealth should be better.

[thin panther]

Figure out how many empty hearts you need to append afterwards

[main lake]

It doesn't work properly when replacing "MaxHealth" by "Health".
Health = 2
MaxHealth = 5

but it gives me only half a heart

[thin panther]

By subtracting the ceil'd Health from MaxHealth

[main lake]

Let me write that up from scratch again because I'm confused by my own code

[visual crest]

How do I do this for when a UI button is pressed? instead of just the mouse button?

[rapid lance]

If I were you, I'd split the code in two.
An initialization where I'd just create the set of hearts (widgets) that I would put in an Array (Your first code would be adapted to this, I'd just replace the SetBrushFromTexture with an Add to this new Array).

Then I'd create a function to update the life.
In this function, I'd use a local variable to store the life to be assigned to the hearts.
I'd do a while loop on the Widget array, if the local value is :

• greater than or equal to 2 : heart full
• greater than 0 : heart half full
• less than or equal to 0 : heart empty
  using the SetBrushFromTexture function, and I'd decrement the local value by 2.

[rapid lance]

The first step is to check the "IsVariable" box.
The button should then appear in the list of variables.

By scrolling in the variable details, you can choose the event you want to listen to.

[visual crest]

Ok I got that

now what?

[main lake]

Ok I have this first part, is it good till here ?

Like I'm trying to get the amount of heart icon that will be generated (empty hearts, half harts and full hearts included)

[rapid lance]

Looks good to me.

[rapid lance]

Sorry I didn't look at the rest of the code, I hadn't seen the whole problem.
I'm sure someone else can help you better than I can.

[main lake]

Now that's where my brain is melting

[visual crest]

Yea I have no clue how to change a drag-and-drop operation over to a UI button pressed instead of a mouse detect.

[rapid lance]

Create an Array variable of type WB_Heart.
In your loop, all you have to do is construct WB_Heart and insert it into your horizontal box.

[main lake]

why would I need to create an array of WB_Heart instead of directly creating WB_Heart in the Horizontal box ?

[rapid lance]

The purpose of storing WB_Hearts in an array is to be able to easily retrieve these objects in another function and access "Heart Img" to change their texture.

But you're right, you don't have to store them in an array. You can probably use your HorizontalBox's GetAllChildren method, but you'll have to cast the widgets to WB_Heart.

[distant hollow]

How would you identify the respective wb_Hearts that you want to change the image of then?

[main lake]

I thought about choosing the right image of the the WB_Heart when I create it and add it as a child to the Horizontal Box. And when the health is refreshed, I clear all the children of the Horizontal Box and start the process again

[distant hollow]

I see what you are trying to do now. If you don’t have to make any changes to any particular items in the container box then yes this method can work, just make sure that you are creating them in the correct order.

[main lake]

what kind of changes are your referring to ?

[distant hollow]

Like if say for any reason you need to animate the last one or whatsoever

[main lake]

I will need to animate the hearts at some point

[distant hollow]

Then depends on how you code them and what is your use case

You’ll probably have to add>animate>add or something

[main lake]

mmhhh that doesn't sound the best option then, what suggestion do you have to solve this issue ?

[distant hollow]

What exactly would be your use case scenario? I wouldn’t be able to advise without understanding what you exactly need.

[main lake]

my use case on what ?

[distant hollow]

On this whole setup

What is your intended outcome and scenario

When you talking about animating, are you animating all of them, or just animating the last one, or a particular one in the middle

Etc

That kind of thing

[main lake]

I'm trying to recreate minecraft heart health system. https://youtu.be/NZrqJzyZpvo

[distant hollow]

I see

So it’s animating all of them

[main lake]

Like for instance when there's a health regen, there's this animation https://youtu.be/PhbnlXetnbA

[distant hollow]

Let me think

I would think that Zhord’s method would be more efficient if that’s your usecase

So you have the widgets created and added to the container but at the same time you should add each one created to an array so that you know which is which

Esp the last one

And when you need to change anything or animate them you can simply run through the array instead of GetChildren and casting as it would be costly

Like in the case of regen it is basically updating the image of one item after another

So with an array it is easy to sift through and find the element index that you need.

Like if your HP is at 4.5 then you trunc it you get 4, which you can use as an index in your array to point at the 5th item, which would be the one with a half-heart image

Things like that

Does the vector variable change both the location and scale of an item while running the game?

[lunar sleet]

No

A vector holds x,y or x,y,z coordinates (i.e. location only)

If you want location + rotation + scale, use a transform

[tame terrace]

but the transform doesn't work in a blank project, also your wrong, vector changes the location of an item, learned from udemy instructor. Is there a variable that changes the scale in game. Or is the location and scale both changed from a vector which I don't know...

[lunar sleet]

It’s you’re* and that’s a bold statement but I’m sure you know best

Also no idea what “transform doesn’t work in a blank project” means in this context.

Transform is a type of variable that holds all 3 of those things

Why my Event binding to a dispatcher in my WB_HealthBar isn't called when I call the dispatcher from my OnRep_Health function from my BP_ThirdPersonCharacterBP please ?

[uncut seal]

why does my character stop running if the distance reaches 350, but when it is less than 350 it just keeps running to the interact target? (checkInteract is running on event tick, and the second screenshot is from my interact target (a chest) )

[topaz gazelle]

Did you spam Print String in your logic. Is Current Interact Target valid?

Is CheckInteract being called? Are the floats for the branch check what they should be?

[uncut seal]

there may be something wrong with when i run stop movement immediately, because a print string will run exactly before that, but my player does not stop, i will look into that

[cobalt gulch]

How can I make the player look downwards with code?

I don't need anything fancy just a teleport

[obtuse mulch]

you can set spring arm rotation or try this

[cobalt gulch]

Y -90?

[obtuse mulch]

idk test it

[cobalt gulch]

ok

I don't think it exists for me

[obtuse mulch]

get player controller

[wanton prism]

Is this an efficent sound trigger?

[obtuse mulch]

why not

reset the do once on end overlap

[obtuse mulch]

but you also can do this

[wanton prism]

oh

[obtuse mulch]

this way the sound will play once anyway

[wanton prism]

tank you

[wanton prism]

i need help with something else how do i make this work?

[obtuse mulch]

error say that you havent set the KEYINPUT variable

its empty

[obtuse mulch]

well it exists but its empty

or the BP_keyfordoor actually

[wanton prism]

no

its filled out here

[obtuse mulch]

well idk, too little information

[cobalt gulch]

How can I increase the speed the player falls with a button press?

Set gravity doesnt seem to do anything for me in terms of speed

[obtuse mulch]

try increasing Z velocity

on movement component

[cobalt gulch]

jump velocity?

[cobalt gulch]

this one?

[obtuse mulch]

yea

or jump velocity that might work too

[cobalt gulch]

it kinda works but it slows the falling speed temporarily

[obtuse mulch]

something in movement component should fix it

maybe braking friction factor?

[cobalt gulch]

oh

i dont think its adding speed

i can cut the speed off entirely but not add speed

[upper badger]

I'm working with the first person template. I made child classes out of the default projectile and made the weapon component spawn those. I added an enemy BP, just a basic character with a skeletal mesh, some chase AI, nothing too complex. I want the enemy BP to react to any child class of the default projectile. Now I'm trying to hit the enemy, but when I fire on it, I never get the print string (see attached). Am I doing this right?

[silent stag]

Hey guys , i am trying to make quest system related with my inventory i tried interface for communicate between them but stuck here.

[obtuse mulch]

check projectile and enemy collisions

the casting is right

[upper badger]

Collision of the projectile's collision component is set to projectile. Enemy collision is "pawn" on capsule component and "Character Mesh" on the character mesh. I think these are all the defaults? I tried using "Block All" on the chracter mesh and still nothing.

[trim matrix]

hi, if i have two transform values can i trace a line and get all the coordinates on that correspond on that line, maybe an array or something, and clamp another transform value on that line so it can move in a straight line? (don't know if it's understandable)

[obtuse mulch]

it might block all but does it overlap?

[upper badger]

My projectile is set like this. My character mesh collision is same as yours.

[obtuse mulch]

tick overlap on everything on both to test

[cobalt gulch]

pls help someone

[upper badger]

ok so I ticked overlap on everything (projectile collision component, enemy capsule component, enemy mesh) and my enemy fell out of the level and into oblivion lmao. I switched the enemy collision stuff back to default. projectile is still has all overlap ticked and still nothing

[obtuse mulch]

you have too keep Block and add Overlap

[obtuse mulch]

ur event is

begin overlap

but ur overlap is switched to false

[cobalt gulch]

I just need to make the player fall faster

[upper badger]

I set the collision preset of the enemy (both the capsule component and the mesh) to custom and ticked overlap projectile.

Side note, I'm not getting that red line between on component begin overlap and the cast node when I shoot at my enemy, so the event is not triggering...

(the enemy is stationary in front my character, can't miss it)

[glad temple]

Ahoy! I have come across a problem I am unable to solve with a Map variable inside a function... So when I set the value inside the function and print the value later, from inside the function, it shows the correct value.. However, if I get the value from somewhere else in the same BP but outside of the function, it defaults to 0... So I can have both a print inside the function and another in the main graph for example, at the same time, and one will print 0 and the other 1 or 2🧐
Here's the snap of code.. First map is to get/update damage values on components, and the second map sets 1 for damaged or 2 for destroyed. I want to know if a component is damaged or destroyed outside of the function:
https://blueprintue.com/blueprint/4nomqda5/

[obtuse mulch]

i would try the event on projectile

[upper badger]

projectile collision component on begin overlap -> cast to enemy bp -> print does work, so that's cool. but i want to keep the collision logic in the enemy bp to calculate for health and such. should i just do on projectile overlap -> cast to enemy bp -> apply damage and then handle the damage calculation on the enemy using the event any damage node on the enemy bp?

[obtuse mulch]

yea thats how i do it

[upper badger]

awesome. thanks a lot!

[silent stag]

This interface communication does not work what am i missing here

[dark drum]

thats because your calling it on an actor that hasnt implemented it.

your calling it on the player controller and not the objcraftitem.

[silent stag]

so i need to make a objcraftitem object variable in bp_firstpersoncharacter

[dark drum]

An actor var is just a pointer to the actual actor which would be empty unless set. Assuming the objcraftitem is in the level already, you would need to get a ref to it and call the function.

[dark drum]

Increase the gravity on the character movement component.

[silent stag]

this quest in the level so still i can not rach the object

[dark drum]

You're trying to get the 'HasInteractedWithKey' var from an actor that has been destroyed. You'll need to provide more information about what you're trying to achieve.

[fervent lantern]

Is there any way to stop data assets from saving in the editor?

i wan't them to stay static unless they are loaded from my save game object

[dark drum]

Oh its a quest system. Really, you should be using event dispatchers for stuff like this. I would assume you have some sort of inventory to manage items that are picked up. When an item is picked up, it would call an event dispatcher (something like 'OnItemPickedUp'). The quest would then bind to the relevant event dispatchers so it knows when stuff has happened. In this case, the OnItemPickedUp event dispatcher.

[silent stag]

Oh thank you so much for show me the right way man

[dark drum]

No problem but yea, ideally nothing should ever need to know about the quest system as it should run on top of everything else. The moment you need to start communicate with quests directly to notify it when stuff has been done, it'll get very messy and become buggy. There would just be to many edge cases to account for.

[silent stag]

So you mean this is too much for my level ?

[dark drum]

I'm not sure what you mean.

[silent stag]

i mean it's too hard to implement for all system

[dark drum]

The current way you're doing it isn't scalable. By the time you've completed you're first couple of quests you'll feel yourself die a little inside at the tought of making another one. 😉

[silent stag]

haha got it but i will keep it simple it's just for introduction not like a mmo

[dark drum]

It doesn't matter if it's not an MMO lol. A quest system is a quest system. 😉

[silent stag]

Can you recommend better or easier way ?

[dark drum]

Yea, use event dispatchers. You would add them in places so other systems can now about stuff that has happened like, picking up an item, using an item, jumping, interacting with an NPC, dying etc... The quests would then bind to these events for what it's needs to keep track of. This means nothing would need to know about the quest system and the quests handle everything themselves.

[silent stag]

Perfect thank you again

[harsh tiger]

Is there a way I can open the Level Assets one after the other and perform some blueprint logic in between ? I want to do this either with a editor blueprint or in c++ if possible.

[prime stump]

Anyone know why Play Sound at Location wont work but Spawn Sound at Location does? so confused lmao

[silent stag]

I can't "Get player character" in object class for casting character @dark drum

[dark drum]

the objcraftitem a child of uobject?

[silent stag]

Child of other object class

[dark drum]

is that a child of uObject?

[dark drum]

Looking at your previous screenshots it looks like it. So uObjects don't have any context to the world so you need to give it a path to it. If you need to get the character, you could create a BPI function for getting the player character. You would then implement this in the BP that constructs the object (assuming it's it's outer). You would then just get outer in the object and use it as the target for calling the BPI function.

[silent stag]

I already using BPI for getting player character

I dont know whats mean "outer" bpi also need object like casting

[dark drum]

When you construct a uobject based class, there's an input called outer. This is like the owner of the object. In the uobject, you can get it's outer (owner) which is it's link to the world in a way.

[silent stag]

can we construct anywhere like this

[dark drum]

Yea, but it's normally a good idea to have a manager that handles it. The last thing you want is multiple quests objects having different outers as it'll become difficult to maintain and manage when you need to get data from the world.

If you have a quest manager that has a function for creating the quests and stores a ref to them. You can then include logic (BPI functions if needed) to get stuff from the world. (if needed)

So how I would structure it is having a quest manager that is of type Actor component that gets placed on the player controller. If the manager creates the quests, it can set itself as the outer so you know that in the quest objects, getting outer would get the quest manager, (in object form so you would need to cast if you need to call specific functions) you could also then get the owner which would get you the player controller (again you would need to cast to the specific type), and then from this, you can get the controlled pawn. (again you would need to cast if you need a specific type)

Assuming other systems use actor components and are placed on either your player controller or character, you can then use the get component by class node to get most of what you want easily without even using a BPI.

[dark drum]

This is my 'AddQuest' function in my quest component as well as a function in my quest object base for getting the owner of the quest. (the player character)

[silent stag]

I understand man thank you for all detailed answers

[silent stag]

It's not gonna work

Today i guess

[dark drum]

In your example, if the player character is constructing the object, the it would be the outer so you can just get outer and cast to your player character. No need to use the BPI function. (Of which you probably haven't implemented on the player character.)

[distant hollow]

If your code is correct the character should be moving diagonally isn’t it?

[dark drum]

Would I be correct to assume your using enhanced inputs?

[distant hollow]

Oh right

[dark drum]

In your Input Action, you can change the accumulation behavior. Setting to cummulative will result in the character standing still if pressing both forward and back.

[velvet pendant]

Hello, I have this problem, that i dunno how to resolve.

1. i created 3 comps , Health DMG, Death.

I setted the Health, the dmg and death, but!

When i hit the enemy, it's does the math [Enemy hp - Project dmg]
Wich is equal to 1.

But, whenever i throw another project, it's goes back to full health [150].

Why?

Also, i'm using Hit component sphere. [my bullets]

[brisk rain]

Hello! I got a button to open the main menu level, however, when i click it it flashes the main menu screen and gets right back to the current level. I also added a print to the main menu button to start the current level and it never triggers. What seems to be the issue?

I also tried adding a delay to where you can't click the start button on the main menu for 1 second after construct and initialize, but it didnt do anything.

[dark drum]

As a guess, I would say there's something in the main menu that's making it go back to the previous level.

[brisk rain]

I dont think so, it only has 1 button and here's the code

as i said it doesnt trigger the print tho

[trim matrix]

space bar == no no

[brazen merlin]

Probably not the answer you wanted.... i would look at the AnyDamage event. It might be strange, but it is what you are setting up without doing it from scratch. (It might mention damage types, but you dont need to worry about them really). As for the calculation, you need to keep track of health as it gets modified. For example, on Damage, currentHealth - dmg = currentHealth, then check currentHealth >= 0, if it is not, they are dead 🫠

[trim matrix]

you can't use the previous input system

[brisk rain]

nope it still doesnt work without it

[velvet pendant]

i did the calcs, as you said

[brisk rain]

ive been recommended this before, isnt there any way to avoid this?

[trim matrix]

no???????

[brazen merlin]

Im going from the current posted pictures

[trim matrix]

you must use it, you can't use the previous version, it is broken and will not work when building your game

[velvet pendant]

@brazen merlin Ty for asking, not really getting it, for a more detalied view : https://www.youtube.com/watch?v=tcqCO_YijpM, if you can ty

And about onanydamage, gonna look for it

[brazen merlin]

Hmmm... from this video, there is collision contact occuring. I would print string to figure out what collisions are happening and also print string if the damage triggers. It might not, i dont know the complete setup.

[velvet pendant]

The damage should be applied, not just to be shown in debug, it's crearly taking Projectile DMG from Enemy Health.. so idk

[dark drum]

Well the old input system is depreciated so... yea. Unless you're far into development, you should switch over to the new system.

Having said this, I don't think it's whats causing your issue though. Do you call open level anywhere else?

[noble ledge]

On the Gate node, if something points to the "Open" pin, will it execute whats on the "Exit" pin or does it only open the gate?

[dark drum]

it just opens the gate.

[noble ledge]

ty

[dark drum]

Ahh, i'm in 5.3. The only way around it would be to split your move axis up into their own input actions then. (as far as I know)

[velvet pendant]

anyone?

[dark drum]

Possibly, backup your project and give it a try. If nothing breaks it might be lol.

[velvet pendant]

i didin't set anywhere to come back to it health..

that s the odd part

[dark drum]

How do you know the health resets?

[velvet pendant]

after each shot, the Print string goes back to 100.

[dark drum]

Show how you're printing the health

[velvet pendant]

if i spam it, it's goes to 88 [health], then back to 100

@dark drum

Enemy's have 111 hp.

so the math it's kinda working

but it's resets

[dark drum]

It's because you have the health component on the projectile. Each projectile will get it's own instance of the health component.

[velvet pendant]

ohh.

but then, how do i substract the dmg if not the health comp there

hmm

[dark drum]

To be fair, it could all be handled by a single component. The health component would be on the character and with the 'OnRecieveDamage' event, have it call a function on the component that modifies the health.

The projectile would just call apply damage on the actor it hits.

[brisk rain]

nope (sorry im late)

[kind willow]

I'm trying to add a slight rotation to the camera when player moves left or right, but I'm having issue with rotating the camera. The camera's roll is controlled using the player input, so I can't roll it blueprint-side. I tried using the "Add controller roll input", but the problem is that there's no "set" node, just "add", so it will just keep adding and never resetting back to 0

[obtuse mulch]

try this

target is player controller

[kind willow]

Yup! For some reason the node wasn't showing up in search, but this works perfectly. Thanks!

[dawn gazelle]

When you execute "Open Level" anything you do after it can be thought to not happen as opening a level causes the engine to essentially destroy everything.

The only thing typically to persist is the Game Instance.

[wooden wagon]

i want to make an ai that stops moving if i look at it (like a puppet or the angels in Dr. Who). I tried it with a box collision for the player (if the ai is in the box collision it stops) and it works but it's not efficient. Does someone know if there is a node that disables movement if the ai is just on screen?

[brazen pike]

"Was recently rendered" might work. I've used dot product before and that works very well

[wooden wagon]

hm i will try it

thx

[magic parcel]

I am a tad bit confused, hopefully, somebody can assist!!! For some reason, the branch node is never going into the Clear and Invalidate Timer node.

This does get set... wait....

as I am typing this... i only do the check on event beginplay

Okay, fixed it moved the branch down to the PlayAnnoyingSound bit 🙂 perfect

[heady burrow]

If I want to make a short lived laser, should that be an actor ?

I guess maybe it's better to just attach a particle system to an actor instead

[timber crystal]

hello guys anybody nows why after players death and respawn my touch inputs do not work any more? and i get an error

[thin umbra]

Hello, can someone guide me on why my viewport resizes upon changing levels?

"[2024.01.27-20.24.34:885][238]LogViewport: Scene viewport resized to 1274x680, mode Windowed."

I am setting my GameUserSettings to different modes like Full Screen, Windowed Fullscreen...etc, but when I transfer to a different level, the screen resizes automatically.

[coarse aurora]

Hi, I'm using UWorld::ServerTravel() and passing in options to change the game mode like /Game/Project/GamePlay/BP_GameMode.BP_GameMode_C, this appears to be working in loading the new game mode, but only the C++ class, it ignores the Blue print instance of that game mode I am referencing? Anyone encounter this?

[lofty rapids]

when does construct run ? i imagine the reference is being killed, you'll most likely have to run that code again to get that reference.

after you spawn it

set the reference ?

or construct runs when the thing is being spawned ?

i have not used that event yet

[timber crystal]

that construct runs always by event begin play in the character BP its a widget

[lofty rapids]

"always" ?

i would check the length of the array

see if they are both in there for some reason

because the reference your using is f'd i think

[timber crystal]

hmm ok let me see give me 3 minutes

[timber crystal]

yes always with eventbegin play so i want that widget as the begin
The reference is going to BP_Third Person Character

im not realy waht to check?

[lofty rapids]

check the length of the array

with a print string

it will also show when it runs

[timber crystal]

ok let me do that

[lofty rapids]

it might be the get 0, if the array is actually empty

or there could be two in there idk

[timber crystal]

sorry im to new for unreal to get you right i try now to add a print string xD
But it shows me nothing ingame

[lofty rapids]

well you have no "power" or execution going into print string

so it doesn't run

and you want the length of the array

[heady burrow]

that Get is not doing anything

[timber crystal]

im not realy sure how to get the lenght of an array

[heady burrow]

drag from the array, search for length

[timber crystal]

yep sorry my fail

ahh ok

[heady burrow]

also, I'd recommend you to make them look prettier, more ordered, symmetrical, etc.
not only for you but for others to help you more

[timber crystal]

sorry it was the fast way

i cant connect now the length with the reference

[heady burrow]

the green pin is the output of the node.

just drag from there and use it however you like

[timber crystal]

thats waht i mean

[heady burrow]

you are trying to use a type of variable thats unusable for your input

[heady burrow]

I'd recommend you to start with much more basic stuff.

[lofty rapids]

ya it seems like you should do maybe some learning of basic node stuff like what the white line does, what pins are and dragging out, into things

[timber crystal]

OK, let's forget my BP for the cell phone button settings, how would you do the whole thing so that when the character dies, the whole thing doesn't bug out like it does for me

[heady burrow]

yeah, so, you are trying to fix something at a much higher level than what you should be trying to learn right now.

[lofty rapids]

for one thing i would probably get the reference different, i'm guessing you want the character your playing ?

where you would get the player, cast to that bp

[timber crystal]

yes

[lofty rapids]

are you using the third person template ?

[timber crystal]

Yes, that's BP_ThirdpersonCharacter. I made a variable for this that serves as a reference

As I said, it just doesn't work anymore after I die once and respawns very strangely otherwise the whole thing works perfectly

[lofty rapids]

so everything else works like your character moves and stuff when you respawn ?

[timber crystal]

yes

just the handy inputs bugs then but with keyboard it works

[lofty rapids]

does the print string show up when you load the widget ?

or is it showing at all ?

it should show up, i'm just not sure when

[timber crystal]

puhhh okok
thank you very much, to you 2 I have tomorow unreal lessons anyway and there is a teacher there too, so we should be able to do that...

but thanks a lot engage god bless you!

[round basin]

Any idea to make this without a select node?

[round basin]

Oh yeah using an array, don't know why I didn't think of that, thank you very much engage!

[thick prairie]

Hey guys. Can objects on the scene mess up UI onClick detection? I have UI element with buttons that renders near my character, but when i try to click or hover over them, nothing happens. When I move them far to the side, they do work. I don't know if there's some hidden collision object that interfere with them, or there's something else causing this issue. I tried to look at the collision presets, but I'm not exacly sure what to look there for.

[lofty rapids]

How would i blow back my character ? It's walking left/right sidescroller and when he takes a hit from this thing i want to blow him back a bit.

i tried add impulse but it didn't work the simulate physics is needed and that f's up the movement

i guess i could just manually move him over time, but i thought add impulse would work

[pine mesa]

Help. I can't find my "Char Object Ref" inside my character's details panel to set the reference. How do I cast?? (New to UE)

[lofty rapids]

wdym in the details panel ? it should be on the left

your not getting any details of the variable ?

[pine mesa]

I followed this tutorial and at 3:35 he adds a reference to the variable, but it's not showing up on my character: https://www.youtube.com/watch?v=IyTxIsjf77k

[lofty rapids]

did you click on the bp in the outliner ?

[pine mesa]

Yes

The full details panel is showing up, it's just missing the variable + I have the variable as public.

[lofty rapids]

you have it expose on spawn ?

[pine mesa]

No, in game, you click a button and it spawns the character.

[lofty rapids]

i'm saying the variable

is it instance editable ?

expose on spawn

when you click on the variable

[pine mesa]

oh, no I didn't have it on. What does that do?

[pine mesa]

yes

[lofty rapids]

it should expose it

when you place it in the level

so that you can get that reference

i'm still learning so i could be wrong

[pine mesa]

Hmm

[lofty rapids]

could only be when you spawn it, not place it in level

[pine mesa]

Ok, so, this is my widget blueprint, which when the button is clicked on my widget blueprint, it spawns the character, and...

The problem: It casts to the character BP to trigger the character event.

But casting doesn't seem to be working.

[lofty rapids]

the cast is just failing ?

[pine mesa]

Yes

[lofty rapids]

did you set the variable default ?

or you can't

[pine mesa]

It isn't showing on the character's details.

[lofty rapids]

you said that picture was your widget ?

[pine mesa]

Yes

[lofty rapids]

so that variable char object ref is on the widget not the character

atleast that's what it looks like @pine mesa

[pine mesa]

Yes

it needs to be on the character?

[lofty rapids]

what exactly are you trying to do ?

[pine mesa]

Click button in widget, trigger event in character.

[dark drum]

Get the owning controller of the widget -> get controlled pawn -> cast to your character BP.

Edit: as an fyi, an object based variable such as a character is just a pointer to the object. As it's in the widget in the editor, it can't be set as the object doesn't exist yet. Doing the method I mentioned above should allow you to get the character at runtime.

[pine mesa]

Sorry, but what is the "owning controller of the widget?" I don't understand.

[dark drum]

Right click in an empty space inside the widget event graph and search for 'Get Owning Player' it should get you the player controller that owns the widget.

[drowsy thistle]

Hi @dark drum, I just sent you a dm about your maze generation tutorial with a problem, could you take a look? or maybe you prefer talking about it here?

[pine mesa]

The cast failed.

[dark drum]

Damn you found me. 😛 jk, what's up? Just post it here, there are plenty of smart people here that might be able to help as well. 🙂

[dark drum]

What is Godzilla selection menu? Is it a character?

[pine mesa]

Yes

[dark drum]

Is it a character the player is controlling?

[pine mesa]

No

[dark drum]

What is it then?

[pine mesa]

A character that's spawned, not controlled by the player, but just to be there as a model in the game visually.

[drowsy thistle]

@dark drum I've been lucky seeing you in this channel 🥹 My problem might be linked to my wall mesh because its spawns in very strange locations, i'm not familiar with mesh editing and pivot point and don't know if i've done something wrong in the blueprint or not...

[dark drum]

How is it spawned?

[pine mesa]

Through a button in the widget blueprint.

[dark drum]

It looks like the rotations are off by 90 (or -90 it's hard to tell) you could try adding it when setting the rotations or adjust the rotation in the mesh itself.

[dark drum]

Is this the same widget that you calling the other button click event?

[pine mesa]

Yes

[dark drum]

If that's, the case, pull from the return value on the spawn actor node and promote to a variable. You can then use this variable in the other place. You probably won't need to cast and should be able to call the functions directly.

[pine mesa]

Like this?
I got an error message:
Blueprint Runtime Error: "Accessed None trying to read property GodzillaInstance". Node: Roar Anim Graph: GodzillaClicked Function: Execute Ubergraph Selection UI Blueprint: SelectionUI

[dark drum]

Show how you set the ref when you spawn the character.

[drowsy thistle]

@dark drum I've tryied multiple rotation combinations thinking it was the problem first but none is functionning. My understanding is that the walls rotate on one edge and if I spawn 4 of them I would get a cross and not a square. Do you remember if the wall mesh have a specificity on the pivot/rotating point?

[dark drum]

Not off the top of my head but I believe I mentioned near the start of the video.

[pine mesa]

?

[dark drum]

I take it you didn't read my reply where I told you to pull from the return value on the spawn actor node and promote to a variable.

[pine mesa]

Oh no, I did!

[pine mesa]

I renamed the variable to "GodzillaInstance."

[dark drum]

Show how you set its value?

[pine mesa]

The variable doesn't have a value?

[dark drum]

So you're not setting its value to the character you spawn using the spawn actor node like I advised?

[pine mesa]

No, I am. The value is set to the character.

[dark drum]

Then show how you set the value. I want to see the set node.

[drowsy thistle]

@dark drum https://youtube.com/clip/UgkxtRHX4-WHLMmq_rus_mhyxbDrbJZTvAq6?si=i6qHwYa8u3T8GR4D You did! Hopefully we met, I was watching on repeat the tile presentation but not that part 😉 Whatever, I don't know how to manage this problem, do you know any way in UE or I need Blender course?

[dark drum]

I think there's a way to modify the pivot point in UE but I'm not familiar with how. Alternatively, blender isn't a bad option a quick overview should be enough to modify the pivot of a mesh.

[pine mesa]

Is this what you mean?

[dark drum]

Yea. Is it working now?

[pine mesa]

YES! THANK YOU!

[true valve]

How do you cancel/abort an event dispatcher

[drowsy thistle]

@dark drum I'll take a look for it thank you for your help, I'll keep you in touch

[dark drum]

No problem. 🙂

[dark drum]

Unbind the function.

[true valve]

Can i send a message to unbind a dispatcher

The actor that has the message will need to cancel it

[dark drum]

The actor can unbind all functions on its event dispatchers so call when needed.

[true valve]

Got it thanks

I used unbind all events xyz

[bitter jetty]

Why doesn't enhanced input y work? This is the code for my look input, but the y-axis does not turn at all, only the x-axis turns fine.

[dark drum]

Remove the modifier.

[bitter jetty]

I did, but it did not change anything

[dark drum]

Have you printed the y value to see if it changes?

[bitter jetty]

Yes, it does print

[dark drum]

So it changes?

[bitter jetty]

Yes

[dark drum]

Then it's not an issue with the input action. It's doing what it should.

Depending on the character setup, it might only be set to use the controller yaw which is why pitch isn't doing anything.

[bitter jetty]

How do I check?

[dark drum]

On your camera/spring arm or movement component.

First person is normally yaw and the movement and pitch on the camera. Third person is normally both on the camera/spring arm.

Edit: the first and third person templates have it setup if you need an example.

[bitter jetty]

I did the exact thing the first and third person template did and it is still not working

[dark drum]

You can get the control rotation and print it to see the values change. This would confirm if you haven't got the relevant components set to use pitch.

[lofty rapids]

how would i apply some sort of force to my player ? like bump it in a direction

[thin panther]

with the add impulse node

or launch character

or a movement input

[lofty rapids]

i tried both

the impulse node is crazy i don't get the simulate physics problem

[lofty rapids]

this worked ty i don't know why it didn't work i tried it before i must have f'd up the numbers

[thin panther]

yeah sometimes they need to be deceptively large

[young edge]

Hello guys I am new to unreal and blueprints but have done some coding and I am trying to have a wave of items spawn lets say after 20 seconds and keep looping this is how far I have got

[thin panther]

a for loop must execute in a single frame.
You'd probably want to set up your spawning on a timer, with an initial start delay of 20 seconds

[young edge]

So right after the event begin play?

[thin panther]

if that's when you want it to happen, then yes

[wanton prism]

ok

[thick prairie]

Guys, I have two widget in a single blueprint. For some reason, one of them blocks the mouse input of the other. I have no idea how to solve this. I tried too google it, tried to play with the behavior section, but nothing helps beside disabling the widget :(. Changing their order would be all i need, but i don't see any option for that :/

[young edge]

Ok I fixed thank you very much 🙂

[celest tangle]

Is there a way to see/visualize a collision box? I'm trying to set an actor's collision box component's box extent in-game and am having troubles telling if it's the correct size.

[bitter jetty]

My player y-axis looking does not work. I checked the first person template as an example and have absolutely no idea what's wrong. I printed the y axis to see if it changes and it does, so I have absolutely no idea what to do now.

[cold lion]

Hi I am having a weird problem where I have made a functional enemy but when placing another in the world or making a child causes this error

Blueprint Runtime Error: "Accessed None trying to read property CharacterMovement". Node: Branch Graph: Handle Enemy State And Calculate Degrees Function: Execute Ubergraph BP Base Enemy Blueprint: BP_BaseEnemy

I need to be able to make child blueprints of this base enemy however this error is messing me up, the only thing I can notice is that the child blueprints for this enemy dont have the general movement tab for character movement. I am very confused as duplicating the enemy in the world space works just fine but making a new one or placing another causes this error?

[wanton prism]

Is this an efficent way to have an invisible barrier untill a player does an objective?

[lofty rapids]

why are you looping from 0 to 0

[wanton prism]

yeah i just realised im dumb lol

[lofty rapids]

you probably want tick

or a timer of some sort

[wanton prism]

I got it to work by using my brain But i get this error and it works

but it works for some reason?

[lofty rapids]

that runs on when the thing loads, but that error probably means theres something wrong with your boolean

or what it's attached to

[wanton prism]

im just going to take your advice i dont want to have to find out later the hole game explodes. il put it on event tick

[lunar sleet]

It means “has been interacted with” is null (hasn’t been set yet)

[lofty rapids]

or a timer of some sort

but if you do it on tick you can get rid of it as soon as you flip the boolean @wanton prism

[wanton prism]

Oops im just lost now

[wanton prism]

il try that i think cause its all mess up now

[lofty rapids]

what is this ?

[wanton prism]

i forgot to name them the same

its just checking the object i found out the problem it turns out for some reason if i dont put a delay until next tick it doesnt work But now the destroy cube works while the sound one doesnt?

Still get this erro

from this one

[lofty rapids]

are you setting a variable on it, then destroying itself ?

[wanton prism]

no

[lofty rapids]

looks like it

[wanton prism]

oh

[lofty rapids]

the set looks like it's in the bp

[wanton prism]

how do i fix

[lofty rapids]

why do you set has interacted and then destroy actor ?

[wanton prism]

for the key

[lofty rapids]

i mean you destroy it

so you probably want to set haskey or something

this is a key for a door ?

[wanton prism]

yes

omg you are so smart

[lofty rapids]

well you put that on the player

and when you get the key

set it on the player

thats where your mixed up

your setting it on the key, so when you destroy it

that variables gone

you want the other actor, cast to your player, get has key

theres other ways to do it i used an array of strings for my keys in a project

[wanton prism]

the has key is on door bp

[lofty rapids]

but how to link that to the player ?

so he knows he has the key

[wanton prism]

doesnt its an interaction system that handels it

[lofty rapids]

so that key only works for that specific door ?

[wanton prism]

yes

[lofty rapids]

nice

[wanton prism]

Are you able to help me with a physics problem? Im having a glitch where the player can fly while picking up and jumping ontop the the object. I attached a video with my problem?

Do i just line trace to check if the player is on top of the cube or do i need the system to check the player velocity? and if its too high stop interacting

[lofty rapids]

maybe shut it off after you take it off or it hits the floor, idk much i'm still learning

[wanton prism]

i make it velocity based as there is a make velocity the player can move at

nope didnt work

[silk cosmos]

Just disable the collision with the player when you grab the mesh

[wanton prism]

Ok i seem to have a problem with an objective system? is someone able to help? this code is calling my objective system but its not working?

[lunar sleet]

That error says it all. Mission Widget is not set at the time you’re trying to access it

I don’t see you creating or setting that variable anywhere

Does anyone know how i can get the y value of my camera? this is my first time using unreal engine and the tutorial im following tells me to do that however they are on ue4 and im on 5. I tried researching online but i couldent find anything, if someone could please help it would be very cool.

if someone knows how to help plz @ me

[dawn gazelle]

You can right click on the yellow pin and there's an option to split the structure.

[raven zealot]

[wanton prism]

How would I fix it?

[cold lion]

Hi I am trying to fix a problem with my character movement, I am trying to make a child blueprint of an enemy that is already working but I have discovered the character movement component is not valid, but the base enemy works fine? I am very confused as I cannot figure out how to change the character movement component

[lunar sleet]

Idk what you mean by that

Did you just create a variable of a widget class or are you actually creating that widget and promoting that to a variable somewhere

[wanton prism]

One of the class

[lunar sleet]

Yeah you can’t do it that way

You need an instance

Not just an empty object

[wanton prism]

It's in the player character

[lunar sleet]

So use CreateWidget, and promote the return value to a variable

[wanton prism]

Ok

[wanton prism]

Am I able to ask but does this code work?

[lunar sleet]

Idk, it’s your code. Does it work?😀

[drowsy anvil]

hello, I have this to spawn bullets, but how do I change how fast the bullets move forward?

[wanton path]

Hey, can anyone help me try to make harvestable nodes?
I roughly know about data assets/tables. But I don't know how to implement them. Or how to make foliage's interactable.

[true valve]

How do you reverse for loop and break?

[main lake]

what do you mean by reverse ?

[true valve]

loop that goes from 10 to 0

[main lake]

You jsut put the first index as 10 and the last index as 0

[lunar sleet]

I mean there’s also a ReverseForLoop node iirc

[main lake]

there's only a "reverse foreach loop"

[lunar sleet]

Ah right

[lunar sleet]

That won’t just roll over to 0? Nice

[lunar sleet]

Adjust the velocity and max speed in the projectile movement component

[main lake]

Simple question : How do people make their First Person Character have a hand shown on the screen for them to be able to use it. But when they switch their camera to third person or viewing that character from someone else's perspective shows something totaly different, like the full body for instance.

By that I'm referring for example to minecraft, where in FPS mode you see only 1 hand on your screen, but when you're in TPS or seen from someone else's perspective, they see the full body and the arm isn't placed in front of the player like on the FPS POV, as the arms are placed along the body.

I don't know how to do something like that, any guidance please ? 🙂

[true valve]

So I have an array of float values. I'm trying to find the lower value of X.

[lunar sleet]

I think they might be using OwnerNoSee?

[true valve]

for example, 1, 5, 10, 15. If X = 8, I want 5.

[main lake]

huh ? But 8 isn't in the array tho 🤔

[true valve]

correct

[main lake]

So you want the first value below your X ?

[true valve]

yes

I can go thru the sorted loop then compare I guess

[lunar sleet]

Idk about interacting with foliage, but if you use actors, making them disappear after a certain amount of collection loops is not too complex

[wanton path]

Can actors still be used in the foliage tab?

[lunar sleet]

Idk much about foliage sorry

[main lake]

• Order your array.
• Go through your array from 0 to the array length (so not in reverse).
• And you check on each iteration if the current number at the current index is smaller than X, if yes, you save it in a variable (for instance do that in a function to save it in a local variable) and you keep going through the loop until the number at the current index isn't smaller than X, then you break from the loop.

[lunar sleet]

Array sorting is much easier in cpp

[main lake]

Also what about if you have 8 in your array (in other terms, what if you have a value being equal to your X) do you return that value or still the value below it ?

[true valve]

How do you order array?

I see a reverse function

[main lake]

Wait what ? How is that possible that there's no "sort"' method for arrays in BP ? Is that because in this case it's a float ?

[lunar sleet]

Or just one of the things they didn’t bother exposing

[main lake]

That's stupid ...

[lunar sleet]

Yeah. In cpp, they literally have a TArray:Sort

[main lake]

I guess you have to write the sorting algorithm yourself (or check tutorials to do that)

[main lake]

That's it ?

[lunar sleet]

That’s what I’ve seen so far, but assuming this is #multiplayer they might also be using different replication tricks

[main lake]

Yeah

I'm gonna ask in #multiplayer to see if they have the same answer, thank you 🙏 🙂

I've changed a struct and now everytime I restart the engine it requires me to redo some nodes like in the screenshot.
I can just remove and add them again, but it's annoying. Is there a good way to fix this?

Where is this "Only exactly matching " criteria coming from?

[main lake]

Simple question : the zooming mechanic in games, is it done just by changing the FOV of the player or there's another way to do that ?

[exotic heart]

I feed a data table row to the struct variable on the widget, everything worked fine until I've changed a variable in the struct. After googling a while, this seems to be a common problem with changing structs later on, but not sure if there's a fix for it

[distant hollow]

Can you hover over these two and see what they say?

[exotic heart]

Interesting. The out row says "s_available_characters", which is correct. the Input says "Fallback structure struct"

I went into the widget and re-set the structure variable, that seemed to fix it!

thank you for pointing me in the right direction @distant hollow 🙂

Is there a way of binding multiple hit events for componants in a ForEach loop? I need to generate hit events for multiple componants at runtime as they are all dynamically created componants but this method is only able to create one event as far as I can tell?

hello i need help with my impact point when ever i dont hit anything with my linetrace it spawns the impact effect on random place and plays the sound too but i only want it to play them when the line trace is hitting something

[dark drum]

I can't see why this wouldn't work as you're binding a function to the 'OnComponentHit' on different instances.

[dark drum]

Changing FOV tends to be the main method but depending on the type of game, you can just move the camera closer or further away. (Change the spring arm length)

I want to make it so this doesnt play when the character is falling

only thing that comes to mind is (is falling) -> not boolean -> result but that doesnt work

also this is the walk run animation

hey guys, quick question on scene capturing and texture streaming. It appears that my items that i wanna capture for inventory icons are very often blurry ingame. Online i found the information to turn on bForceMipStreaming on the item mesh components so they don't appear blurry. I'v done that and it works, my question is now does that come with any performance drawback that i would have to worry about? There are about 500 meshes at the same time on the map, all with this option enabled.

[empty gust]

ok wtf is happening my character doesnt move any more and if i spawn mid air i cant still move and i just stay mid air

Hi, I've been looking at how to implement an upgrade system for my game where every time you level up you get to pick from 3 different upgrades and apply 1 to the character. I was wondering what the best/easiest way to implement this would be. I would like each upgrade to have its own logic as the upgrades won't be as simple as just a stat change.

[lyric quiver]

this should work but you have to make sure you set the variable to the player isFalling in the event graph as well otherwise it won't do anything

[uncut seal]

anyone know why this ability is either not dealing damage (even when hit is triggered) or dealing damage multiple times?

my joystick is not visible in any game or in any project i clicked on show touch interface nut still not working lz help

Does anyone use this instead of AI Move To?

Ai move to is really bad for performance

dropping to 50 fps with AI Move To with just like a 100 pawns with just planes, its not a joke

So getting just the path, and then vinterping the units in C++ is way better

Anyone know of this? Or other alternatives?

CMC is not very performant when there are so many of them

especially all the "accurate" movement default setting is on

depending on your game, you may not need the full feature of CMC? if so you could just do constant interp yourself

[kind estuary]

okay but its just 100 pawns with planes and sphere collision

[kind estuary]

in my case it seems i can get away with these checkpoints

though it seems weird to make games and being limited to 100 pawns

but if its an fps then maybe its okay

How can we change widget render opacity inside the widget ?

Im changing render opacity of a widget from a actor. But i want to reset the opacity when mouse hover inside the widget.

https://gyazo.com/81a1e1e96fcaf6146d68c2434d124706 Not working

[stuck sentinel]

that doesnt work because the output of not boolean is a boolean and result doesnt take boolean

[lyric quiver]

you can add it is a condition going into that state

[stuck sentinel]

i will try that thank you

[drowsy anvil]

how do I make this automatically spawn projectiles, instead of me pressing a button?

event tick was too fast, how do I delay it?

[stuck sentinel]

i was gonna say event tick lol

[lyric quiver]

you could use a timer or a delay

[stuck sentinel]

do event tick and then add a delay node

[remote meteor]

use a timer...

[drowsy anvil]

it wants me to plug something into the event, or is this wrong timer?

[lyric quiver]

put the spawn actor into a separate custom event and plug the red node of that into the event of the timer

and tick looping

[uncut seal]

how can I limit this so that my dummy will only receive damage once (instead of multiple times (if more than one spheretrace hits it))

[lyric quiver]

try the do once node

[tawdry mural]

Custom event

Then spawn projectile from it

[drowsy anvil]

there's no red node here? I made a new function on that sidebar

[tawdry mural]

Not after set timer

[uncut seal]

when i tried that, damage didnt work at all...i wouldn't want to use it anyways though, because i could deal damage to 2 different enemies in 1 hit (for context, this function is running multiple times throughout an attack animation

[lyric quiver]

How would I prevent two objects being picked up at once

[lyric quiver]

you could have a bool like hasItem and make it so you can only pick it up if it's false

[fleet cedar]

Where would I put that boolean? On player controller?

[lyric quiver]

set it to true when you pick up an item

mb caps lol

false when you deselect it

[drowsy anvil]

it fires once, but doesn't loop eventho I tick the loop on?

[fleet cedar]

Another question, how can I handle the switch in control schema, for example, when the player is walking around in First Person, but then a different set of controls when interacting with the objects

[lyric quiver]

is anything blocking the spawn pos?

[lyric quiver]

what version of ue are you using? You could try input actions and mappings if you are on a late enough version
