blueprint

[dawn gazelle]

Or you're saying that the name one is not working at all?

[river wigeon]

yeah

no idea why nothing happens, when i use that, level ref. works fine

even when i copy out the name

[void cobalt]

question, how could i make a pool of names and pick one out at random?

like a raffle

[dawn gazelle]

Create an array of names, then you can get a random int in range from 0 to last index of the array from the array.

If you don't want the name used again, remove it from the array.

[void cobalt]

how do i make an array?

oh nvm haha

i typo'd "make array"

[dawn gazelle]

You can also predefine it in a variable if you want to reference it. Click on the little bar beside a variable type and click on the object that looks like a rubix cube.

[void cobalt]

so i made an array with names of bones, and i want force to be applied to one of the bones at random when the func is called

i see that there is a node called "shuffle"

that sounds like something i should use

but idk how

[flint vector]

just use get random

[mortal cradle]

Was this debugging system ever created? https://www.youtube.com/watch?v=RwbkvUEgCls&t=2727s

[void cobalt]

how do i find that RANDOM node

nvm

lmao this keeps happening

i typo'd again

[bitter ingot]

hey guys im trying to implement this c# function into a bp function, is there anything i did wrong i dont see the error?

bool inside = false;
    for ( int i = 0, j = polygon.Length - 1 ; i < polygon.Length ; j = i++ )
    {
        if ( ( polygon[ i ].Y > p.Y ) != ( polygon[ j ].Y > p.Y ) &&
             p.X < ( polygon[ j ].X - polygon[ i ].X ) * ( p.Y - polygon[ i ].Y ) / ( polygon[ j ].Y - polygon[ i ].Y ) + polygon[ i ].X )
        {
            inside = !inside;
        }
    }

    return inside;

[earnest tangle]

I don't think it's implemented correctly

You assign to PointX and PointY only once

[dawn gazelle]

In your loop you're setting J's value to the index -1.

[brittle sky]

does anyone know why this isnt affecting my material?

[void cobalt]

do u know why i could be getting this error?

[dawn gazelle]

You're referencing an undefined variable.

[bitter ingot]

But isn't that done too in the original loop?

[void cobalt]

this is what im doing

[dawn gazelle]

WeaponRef is not defined.

[void cobalt]

how do i make it defined

[dawn gazelle]

You have to set its value

To whatever it is you're trying to reference.

[void cobalt]

well im trying to reference a vector

which is set in another blueprint

and im calling it with the ref variable

ive done it before and it worked fine so

idk what to do

[dawn gazelle]

there is nothing in the code you posted that indicates J should be the index -1. The only part that says J = polygon.length -1 is indicative of what is required to exit the loop, so the loop will end when J = polygon.Length -1.

[earnest tangle]

That's actually not true... it uses j as some kind of weird secondary counter

it's just super confusing because it sets it up in the for header

instead of doing the sensible thing and setting it up as a separate variable

[bitter ingot]

I guess I will replicate it in cpp to avoid those errors

[earnest tangle]

yeah in C++ you could pretty much copy it one to one :P

just int32 instead of int

[dawn gazelle]

Yes, it uses J as a secondary reference, nothign wrong with that, but the second argument in a for loop is always the exit condition of the loop.

[earnest tangle]

Yeah but it doesn't use j for that

[dawn gazelle]

Sure it does. The third part of the loop says j = i++, so J then becomes i + 1.

and because it has ++ there, I imagine that I is also being incremented.

[earnest tangle]

Look more carefully :) It uses the rarely used syntax where it allows defining multiple variables in the first part

the loop condition is actually i < polygon.length that's after it

[dawn gazelle]

wow, I am blind

XD

[earnest tangle]

that's why I said it's super confusing because that syntax is very rarely used and just makes the loop hard to read

lol

[dawn gazelle]

How are you calling it?
When you define a variable of a different blueprint object, all you're doing is saying that the variable can contain an object of the class of blueprint. It does not mean you can reference the variables within the blueprint without first creating said object and setting its reference.

[severe geyser]

fixed so much today, thanks to everyone who put in a word of advice. Last question for me, more of just a clean up. I notice that sometimes when I start my game in Standalone as I am playing and clicking it sometimes grabs the side of the window and tries to resize it. The cursor is disabled but I guess it's position sometimes lines up with the outside window and when I click to attack, it grabs and drags the window, pulling me out of fullscreen. Any suggestions on stopping this?

[dawn gazelle]

Example: You can create a character blueprint, called "BP_Character". Inside of the blueprint you have a boolean called "Alive" which is by defalut set to true. I can spawn 5 different "BP_Character" in the level, each with their own "Alive" variable. I need to reference a specific BP_Character if I want to check and see if "Alive" == true.

I can also create a BP_Character reference within the BP_Character blueprint which I could name "Enemy Target". Unless I specifically set that reference, how would the engine know which one I would want to set as the "Enemy Target"?

[severe geyser]

found it. Searched "Resize" in the project settings. Unchecked Allow Window Resize.

[void cobalt]

well im calling it like this

[dawn gazelle]

Ok, and where are you setting "Weapon Ref"?

[void cobalt]

its a variable

set as object ref

[dawn gazelle]

That's not setting it. That is declaring it.

You're saying "This variable is of this type".

[void cobalt]

oh would i have to cast it?

[dawn gazelle]

Not "This variable is this particular thing"

No, casting is only a means of taking a generic reference of an object and getting a more specific reference so you can access its variables and functions. For example, I can have an "Actor" type object reference but it doesn't let me access the "Alive" variable I set on the BP_Character I mentioned above. I can cast the Actor reference to BP_Character, and then I can access the variable, but only if that Actor reference contains a reference to an object that inherits from BP_Character.

Getting a reference to something requires it to exist.

If it exists, and you want to reference it in another character, than that thing must somehow be interacting with that other character, no?

[void cobalt]

idk, up until now this and casting bp's was the only way i needed to reference stuff lol

it works usually

[dawn gazelle]

Casting is not referencing. Casting is only getting more specific.

[void cobalt]

then how would i get this variable from my weapon to the enemy?

the "velocity direction" vector

[dawn gazelle]

How did you detect that the enemy was hit in the first place?

[void cobalt]

a linetrace

[dawn gazelle]

Ok, so then with that linetrace, you probably executed some kind of function on the enemy?

[void cobalt]

yeah, lots

apply point damage, spawn damage numbers

actually thats only 2 lol

i thought i had more

[dawn gazelle]

Ok - so that's the thing, you can pass a reference of your weapon to the enemy at that point, or better yet, just the impact direction, the enemy doesn't need specifically your weapons reference.

[void cobalt]

how would i do that then?

[dawn gazelle]

If you've done it for all those other things, then you can do it for this. It's the same thing.

You're passing a value from one actor to another.

[void cobalt]

velocity direction is set here

[dawn gazelle]

So instead of setting it on your weapon you either:
A) Want to have a vector variable created on your target enemy blueprint (ie. where you're doing your ragdoll check) and set the value on them, then you can get that variable and plug it into the impulse node directly.
B) Have a damage dealing function or event (not sure if you're using the default UE4 damage nodes) and one of its inputs should be a vector. On your hit result, you would call this function or event and feed in the vector and then the function or event on your enemy can use the value can be used as you like (you can pass this along to where you may need it, like in your Ragdoll Death function)

[void cobalt]

yeah im using default ue4 damage nodes i think

like this one?

[dawn gazelle]

Yeah, so you probably don't want to have to recreate the damage system, and that's fine. So just create a variable on the enemy.

[void cobalt]

but then how do i feed the same data into that variable

if i dont have access to that data in this bp?

[dawn gazelle]

Are you doing any casts from your Hit Result's "Hit Actor" pin?

[void cobalt]

this event any damage is inside of my enemy

yes i think

yes

[dawn gazelle]

Ok, so create the vector variable in your enemy.

Hit the compile button after you do (it's important to compile so you can actully use said variable)

[void cobalt]

ye

i know that much :p

[dawn gazelle]

Then on your hit result, after your cast, drag off from the blue output pin on the cast and then go to create a node by right-clicking and start typing "Set <your variable name on your enemy here>"

[void cobalt]

ooooooo

that makes so much fucking sense

i didnt even think of doing it this way

[flint vector]

does the add impulse node work without simulate physics on

[void cobalt]

yes

oh

no

it only works without simulate physics

what are you trying to do panda?

[flint vector]

make knock back

[void cobalt]

ok its ez pz

i was struggling with this for months

but all u need is a launch character node

[flint vector]

didn't realize that was a thing

[void cobalt]

me neither

[zealous moth]

300 messages since last time, what the heck went on here

[void cobalt]

everytime i asked someone to help me with knockback they all said i had to use animations

which is bs

[dawn gazelle]

lol

[void cobalt]

it didnt make any sense at all

[dawn gazelle]

No it doesn't.

[void cobalt]

but every one of them said it

[flint vector]

i knew i shouldn't use animations but didn't realize that launch player was a thing

[void cobalt]

well now u know :p

[zealous moth]

"knockback" in some games means a slight interruption using an animation. What you mean is "launch" and you know it

[void cobalt]

when i say knockback i mean physically knocking the player back

not just nudging them

that would be flinch

[flint vector]

yea

[zealous moth]

the literal only game i ever heard of flinching is pokemon and it skips a turn

[flint vector]

i'm trying to make a wall that launches you back so animations just wouldn't make sense

[void cobalt]

literally every first person shooter has a form of flinch

which is aimflinch

u know, when u get hit, ur character reacts to the hit with an animation

[zealous moth]

you mean wincing?

[runic urchin]

has anyone taken a dive into the car configurator? Looking to get something similar setup for my own camera system but without the ui component.

[void cobalt]

wut

anyway i gotta brb for a sec

[zealous moth]

@flint vector btw based on what you wrote, you want "launch" node

[flint vector]

yea someone else told me that

[fallow bloom]

What's the closest one can have for an octree in blueprints?

[zealous moth]

for... graphics?

[sick temple]

Hey everyone! Is there any way to recreate WarpZoneInfo in Blueprints ala Unreal Engine 1/2?

[fallow bloom]

for actors placed in the world

Iterating a grid would be unfeasible

[zealous moth]

yeah just read up on it. Apparently this has been reused in other fields

[fallow bloom]

I wonder if there's anything that one can use purely with blueprints, got an idea for something and don't wanna use C++ for that experiment

[zealous moth]

🤷‍♂️ maybe...

[trim matrix]

if i have an animated character from blender that i have madea animation bp and blenderspace for, and the 3d model creator changed an existing animation or adds new one, can i add that with out redoing the animaton bp / blenderspace.?

[stable smelt]

If you want to change an animation, just rght clic the animation in question like "idle69" idk xD hit reimport with new file, and select your new fbx or anim file and it will replace it over all your abp

If you have another character with the same skeleton and you don't want to redo the whole bp, you can setup animation retargeting https://docs.unrealengine.com/en-US/AnimatingObjects/SkeletalMeshAnimation/AnimationRetargeting/index.html right clic the animation blueprint, hit retarget and it will retarget the whole blueprint and copy all the animations you used to the other character.

[trim matrix]

thank you so much ^^

I have my character able to spawn a 3d actor to stand on , to get over a long jump more easy for example, I wonder how to go about making it to after i used it 2 times and have two of those actors spawned, when i spawn a 3rd one, the last actor gets destroyed so there is never more then 2 actors out at a time and it cant be spammed

[spark steppe]

store a reference of them in your main character

[lofty vessel]

Is anyone know how to do random loading screen in widget blueprint?

[sick temple]

Any way to implement a see-the-other-side type of portal through blueprints (kind of like WarpZone from UE1 through 3)? I've tried a number of iterations and there's always some way the scene capture camera breaks/ruins the immersion if an object is nearby on the other side.

I have the UnrealScript for Unreal Engine 1's version of WarpZone on hand if that would help, but I have little idea on how to convert the viewport/camera logic behind it into blueprint form

https://pastebin.com/DjgGCJrD

[maiden wadi]

@sick temple Most likely this is going to be render target area. I haven't personally done this, so all I can give is generalized advise, but you more or less just need to make a portal from a material that is being updated from a render target camera that is the view on the other side.

[sick temple]

If I'm understanding correctly, I believe I tried that. The problem mainly comes in with having the render target camera align with the player camera to give the illusion of depth, which breaks easily and ends up causing problems if anything is nearby and breaking the illusion.

I saw earlier in this channel that "making the capture component camera an absolute-transform thing that's set by logic in worldspace each frame" would be cleaner than having it be done through pawn-relative rotation, but I have no idea what that even means to be able to implement it into blueprints (no further explanation was given on it)

[maiden wadi]

@sick temple Presumably your portal is an actor, with it's own camera for the render target. If it is, all you really need to do is get the local camera manager, get the camera's world location and rotation. And then you can affect the portal's look no matter which camera you're looking through because the camera manager's camera should be whatever your current view target is.

So.. simplest math is likely to get the portal location. Get a look at rotation from the CameraManager CameraLocation, to the portal location. And set the portal's camera to that rotation.

[torn sundial]

Hey Everyone!

Does anyone know if it's possible to make a Screenshot from Console Command (or other method in Blueprint) in which I can capture the screen including the Stat Info ?

Per example, I want to take a screenshot that includes the FPS or UNIT values, so it looks like the one I took manually.

Is there a way?

This is to make a Performance Auto Capture basically.

[stray wagon]

Doing this makes the game run at a ridiculously low FPS ? (like...From 90 to 5)

Is there another way to do this ?

same issue @trim matrix

C

Yes there are hundreds

[dense tulip]

Is there a version of UE4 that has good support for 2D

[stray wagon]

Actually if I simply move boxFake to not be a child of the static mesh but add a scene root instead as parent, I dont need to call setAbsolte and it solves the issue

So I guess I'll keep it like that, I'm very surprised this is causing an issue though

yep

[dense tulip]

I guess i mean about making things .. i been trying a tutorial and there are always artefact .. seems like its not usable

i get those artefacts all the time !

I guess what i mean is using tiling to make large maps

ok, i'll try a few things

Oh, i guess i was not using Paper2D the right way, found a video from Epic that seems to work properly

[elder gulch]

How can i fix this?

[trim matrix]

@elder gulch can u be specific with your problem?

also hook player controller to owning player

[elder gulch]

The thing is im trying to set the zorder of the crosshair's zorder from the blueprint but i dont know how to

[trim matrix]

u already set the z-order there to -1

[elder gulch]

done

[elder gulch]

the target?

[trim matrix]

the crosshair

is there a specific problem you are facing? is the z-order not working for you?

[elder gulch]

i promoted to variable but now how am i gonna get the target am i gonna get crosshair and plug?

[trim matrix]

If you already set iti as a variiable

then u can just call it using the variable

[elder gulch]

owh

lemme try

[trim matrix]

I haven't seen u setting variable for the widget tho

u get a crosshair target as a variable, but that's most likely an empty variable

[trim matrix]

was that variable inteded for the newly created widget?

Yea I knew it

u haven't set it

right click set Cross hair target

then u want to plug the return value from the wiidget

to the variable

then u can call and change the z-orrder

[elder gulch]

like this?

[trim matrix]

Just connect to cross haiir target firrst

then u can call it

Let me show u

[trim matrix]

this way u can call the variablee in any place

[elder gulch]

owhh

[trim matrix]

easy way to make it the same varriable is by draggiing the return value and click on promote to variable

[elder gulch]

yea i did promote to variable w,th right clicking on the node

[trim matrix]

anyway what I see from your screen is, you are trying to hook different variable

Don't call it canvas target imo

[elder gulch]

ok xD

[trim matrix]

it's crosshaiir

[elder gulch]

done :D

[trim matrix]

u will be confused laterr

just sayiing

[elder gulch]

Hi, I would like to know, if you had any tips to move one arm based on the mouse cursor ? with events like InputAxis LookUp/ InputAxis Turn ?

What should I search for ? IK looks a bit too complex and not necessary

[lament trail]

Im using 'Draw Material To Render Target' on tick. Is it then possible to get the texture from the render target during that same tick?

[sturdy verge]

I know it's not good practice, though is it still possible to spawn an actor in construction script? The old way with Custom Script (calling SpawnActorFromClass there) doesn't seem to work anymore.

[maiden wadi]

@sturdy verge What is the use case to spawn an actor in the construction script?

It's not just bad practice, it's literally disabled for a reason. Construction scripts are called often in the editor, and dragging something around will spawn a ton of new actors.

[night zinc]

hey guys i need some help

i have changed the Player Control Class and the Default Pawn Class to my own, not the default ones, but when i play, i still spawn with the default Control Class and the default Pawn

[maiden wadi]

@night zinc Where did you change them? If no game mode is specified in the Level, it will default to the project's default game mode.

[night zinc]

i edited FirstPersonGameMode if that's what you mean

[sturdy verge]

@maiden wadi Generally I could do it by hand, setting references to other actors, yet it seems more practical to spawn necessary actors, so other team members don't forget placing

[maiden wadi]

If there's no other way, I'd recommend disabling the construction script while dragging at least, and also keep a local pointer to the actor, and make sure destroy is called on it before spawning and setting a new one. But I remember there being a work around where you can create a function do the spawning logic in the function and call that from the construction script. Because the script only checks the direct function call, not what the function itself calls.

@night zinc And is your game mode set in the level or the project settings?

[night zinc]

project

[maiden wadi]

If you go to the main editor window, and open the WorldSettings tab, your level should have this in there somewhere.

Make sure GameModeOverride is set to the one you want, and that the selectedgamemode settings are correct.

[sturdy verge]

@maiden wadi I tried the workaround in 2.6, but it seems not to work anymore

[night zinc]

those are both correct :/

[maiden wadi]

Hard to say then. The level settings should override project settings. Only other thing that usually affects default behavior is if there's a pawn in the level set to be the default possessed pawn, or if the GameMode's spawning functions have been overridden.

@sturdy verge In 4.26 you mean?

[sturdy verge]

yeah

[maiden wadi]

I'll check, but it should still work the same.

[low marsh]

hi don't know if i can ask this in here but does anyone know why i can't set a parent socket on a niagara system that i have only just made and placed into my character blueprint it says it's an inherited component but i haven't made i that way so i don't know why thats happening?

[maiden wadi]

If you placed the component into that blueprint, it shouldn't be inherited unless you then move to a child of that blueprint. What is the error?

[low marsh]

it says can't change socket on inherited components so i just made random test niagara systems to see if i had done something wrong on the previous ones but it just does the same thing everytime won't let me add in a socket

[maiden wadi]

@sturdy verge Oh snap. They downright killed that functionality. 😄

[sturdy verge]

thx! well seems i need another solution :U

[cyan iris]

Good afternoon, I decided to create a 2D top-down game in UE4. I created a paper character, that use flaying move mode, and I wanted it to changing direction immidietly. I mean, while I holding W, tapping D makes a character to change move direction smoothly and this isn't what I want. Is there any way to fix that?

Ok, nevermind I made it by myself XD

[upper linden]

what's the possible max length of a linetrace ?

[stray rain]

Hei guys, I have a bomb, when the bomb explodes, 4 projectiles shoot out. what can I do so that the projectiles destroy other bombs but dont collide with the bomb they originate from?

[rich axle]

you could ether use collission channels, or check on collision, if the bomb is the "originBomb" (a variable that you pass each projectile when it spawns)

[shadow sedge]

i fixed it me silly

[brittle mortar]

How to get the maximum value from the array (float)

[stray rain]

mmmh okay, I dont know how to pass individual variables yet, I will try to deactivate the collision on the bomb itself just before exploding I guess?

[rich axle]

Not that hard. In the projectile blueprint create a variable of type Bomb. Then when you spawn the projectile make a new node and say "set originBomb"

[rich axle]

Could lead to unforseen bugs later on.

[atomic salmon]

@brittle mortar there is a node called Max of Float Array

that's what you are looking for

[brittle mortar]

Yes thanks I just found it on the wiki

[atomic salmon]

otherwise you need to loop through each element and store the maximum value in a variable by comparing the value of the current element with the maximum value found until that point

@upper linden max float, but I doubt you want to trace to that distance.

[upper linden]

maximum i can get is 20000 units

[barren salmon]

hello i am having an issue where i cant fix this perspective change from set target view blend

[atomic salmon]

@upper linden how do you set your Start and End locations?

Also consider that the further away from the origin the less accurate the physics is, so if you need to trace at such large distances you may consider a different approach

[upper linden]

i'm well within the bound distance

1sec

@atomic salmon

hit result start showing at 20000

but i take the Distance pin from BreakHitResult, is it wrong ?

[azure bolt]

The code is doing what I want it to do but it keeps throwing me this error. Does anyone know how to get rid of it?

[astral estuary]

that error says that your array is empty

so when you try to get an element, you get an invalid object

(i think)

[rich axle]

you could do a check if the array length is > 0

and then combine it with the branch with an OR

[trim matrix]

seems like there is no mining panel existed

[rich axle]

or AND depending on your logic

[azure bolt]

I'm not sure if I did this correctly but it didn't seem to work

[rich axle]

You did not do it correctly. From the array output of the "Get Widget..." get the length and check if it is bigger then 0

put a branch before your current branch.

If it is 0 it is empty and wont do anything. You get rid of the message.

[azure bolt]

Thank you very much. that fixed my error

[rich axle]

happy to Help 🙂

[elder gulch]

Hello everyone for some reason when i press the e key its not printing at the same time im not seeing the linetracesbychannel so is the "E" Key not working or did i made something wrong?

[last abyss]

did you bind E to the inputaction interact

[elder gulch]

Yep

[rich axle]

Sorry for the question, but are you sure you are spawning the correct "ThirdPersonCharacter" class?

[elder gulch]

i think i am spawning the correct one bcs after i added variables it was open to edit from world outliner

[rich axle]

on the right side where it says "consume input"

can you check the box and try again?

[elder gulch]

aight

nope nothing changes

when i change e to l it works

[stray wagon]

What si the correct way to have a map of arrays in BP?

This code always return a length of 1 for the array

Even thought I am adding things to it, which i am assuming is an issue with the FIND sending a copy and not a ref

[last abyss]

does your controller have something that consumes the E input?

[dense isle]

Why does Unreal Insights not profile Blueprint code? How can I force it to include metrics from the BP layer?

[elder gulch]

hmm lemme think

[dawn gazelle]

So what you're doing here is having a structure that has an array within it, and then you have that structure as part of a map. When you're doing a "Find" on the Map you're only getting a copy, not a reference to the structure that contains the array, so adding things to it does not manipulate the structure, nor the map.

What you would need to do, is store the array in a temp variable (best if this was done in a function so you can use a local variable), add what you want to the array, then add the value (your struct, containing the array) back into the map - so long as the key is the same, in your case the vector, then it'll overwrite the previous entry.

[stray wagon]

Thanks Datura ended up creating a higher order function lib storing the local var

a bit similar 🙂

[royal kraken]

Hi All, how can I turn off a range of actors with a keyboard button? I made a blueprint and added an object but having trouble adding that function in the player character to turn them off

[last abyss]

what do u mean by "turn them off" ?

[jaunty solstice]

Any blueprints gurus able to tell me how you might load and parse an external web absed API? In this case the api in question is

https://api.nasa.gov/EPIC/api/natural?api_key=DEMO_KEY

[lost schooner]

anyone know why my projectiles wouldnt collide with anything other then pawns, even tho they are set to overlap all, also bounce doesnt work, my collider is set as my root component which seemed to be the most common cause of this.

[royal kraken]

Hide from camera, so when I press a keyboard input the object in thr blueprint hides then press it again and they re appear

[dawn gazelle]

VARest plugin (free) at least can get you the data. From there you kind of need to use the nodes it has to break apart JSON requests like that.

[stray rain]

if you want them to collide then you would have to set them to block I guess

[lost schooner]

yea, I tried that and it had no effect, from what I understand it shouldnt need block because the projectilemovement component should hijack it and use the fake physics it has

now I try setting it to block againa nd it magically works this time lol...

okay, w/e thanks for the help lol

[stray rain]

cool 😄

[jaunty solstice]

@dawn gazelle Thanks!

[lost schooner]

got no idea why, but it all just works now, thanks for the suggestion, I guess something else was off/on that made it not work.

Hey, I am pretty newbie when it comes to unreal engine and I am struggling to learn from youtube however most things either change or not work with my project. Could I find a master here or can someone point me to the right direction? I am trying to make a moba and I have issues either with character selection (not displaying certain things on the other screen) or trying to add stamina + life and when I found a good tutorial on turrets, I get only half way before something not matching to op. (I get the dev message but not all and the projectile not shooting)

[sturdy herald]

Hello! There is a way to create folders in the game library? Im making an application with UE for university event with a quiz, which can be completed only once. I thinked maybe if i create a file, folder anything with blueprint, when they completed the the quiz and i check from blueprints in the beginning, if exist that files, i can avoid that, users complete the quiz at every launch. Just i dont know how to do it in Unreal Engine.

[gusty cypress]

Is it recommended to use level streaming for creating a loading screen? If so am I expected to have 50 levels all being streamed with the parent level being my menu???

[shadow sedge]

I have my play button set to start at a certain camera which can switch to other cameras with the keyboard (the nodes require begin play event) but then my UI widget which was also on a begin play event dissapears, or if i try to connect them differently the keyboard shortcuts will stop working, is there a way to get the UI to show without a begin event node or should I do something different?

[surreal shore]

Wow, such empty 😅

[azure bolt]

Hey does anyone know how to get the default BP_sky_sphere material to change from night to dawn a little later? I know its something to do with the sun angle but I don't know what value to change

[atomic salmon]

Rotate the directional light in the level

[azure bolt]

Sorry I should have explained a bit better. I have a system that rotates the sun around in a day night cycle. When my clock is at 18pm my sun sets, which is about right. but when my clock is at 1 am it becomes dawn which isn't quite right

[rich axle]

Has anyone ever used the "Merge" function within blueprints when working with Perforce? Got some questions about it!

[atomic salmon]

@azure bolt are you doing that by manipulating the sky sphere and the directional light? You may need to map the angle of the directional light to time of the day differently

Depending on how you are doing it you can use Map Range Clamped to do that

[azure bolt]

Basically this

[frank nest]

This should be pretty simple but its not clicking in my head haha. I have an array with two montages. I have been able to use random integer to play them randomly but I want to play the first one then the second one and then reset. A the moment incrementing it just plays the second one over and over again

[atomic salmon]

If you want a fine control from time of the day to angle, the best option is to use a float curve for that.

[frank nest]

I thought a loop might work here but I dont know how to set it up I guess

[left niche]

Increment it then modulo with the length of your montage array.

[azure bolt]

Where can I implement this?

[atomic salmon]

Create a new asset in the asset browser or type float curve

[frank nest]

Awesome! do you have a screen shot per chance of this set up? If not no worries 🙂

[atomic salmon]

@azure bolt then set the horizontal axis from 0 to 24, that is your time of the day. The vertical axis is the corresponding rotation of the sun. Set the key values of the curve to establish the relation between time of the day and rotation of the sun.

[atomic salmon]

@azure bolt Then in code use Get Float Value to pass the current time of the day to the curve and get the corresponding sun angle as output.

[maiden wadi]

Should also consider a macro for the montage thing if nothing else is affecting that counter. One less property in the class variables list.

[frank nest]

Amazing! Works perfectly

[frank nest]

Macro? Is that So I can use the same counter for all attack stuff like this?

[maiden wadi]

Sort of. Macros exist inline. Meaning that if you copy a macro, it's local variables can differ depending on the execution flow fed into them.

[frank nest]

Ahh okay so as long as I have a counter variable leading into the macro then it will work

[maiden wadi]

Meaning that if you do this.

You don't have another variable here.

However.

If you do this. And you press Z twice and V once. Then Z will return back to 0 if your array length is 2. While pressing V again will play the second animation because it has a different local integer than Z

It's just a way to keep your blueprints from becoming exceptionally populated with unnecessary variables. But like I said, don't do it if you need to affect that integer elsewhere, like a timer reset.

[azure bolt]

So something like this?

[frank nest]

Okay thank you for the high level advice this is a good thing for me to learn! I will look more into it so I can understand it better 🙂

[marble echo]

can anyone see what might be going wrong with my reloading system? sometimes it counts the first branch as true, even though ammo in the mag is not more than the ammo pool

[worthy frost]

that reload looks weird

also weird you have a sequence player

[marble echo]

the sequence player is for a really simple reload animation

[atomic salmon]

Yes looks good. The vertical axis of the curve should be degrees, so from 0 to 360.

[maiden wadi]

@marble echo You could try something like this. Less branchy.

[marble echo]

Thanks, this is what I get when I try it out however

[maiden wadi]

Oh, whoops. Best not to have two different trains of thought when making something.

[marble echo]

with the rest the same?

seems to add entire ammo pool into the mag

[maiden wadi]

Yeah. This will change it to select either the rest of the pool if it's less than the max you can load into the clip. Else use the max you can fit into the clip.

[marble echo]

ahh i see what you mean

Thanks for the help!

hmm wait no i dont, think I need to rethink this lol

[maiden wadi]

What is that first branch on the bottom?

[marble echo]

its checking if the current mag size is more than your pool, and should add accordingly

do i need another branch before the first one with the original stuff in?

like before the brown part?

maybe i just need to scrap it and start agin

[void cobalt]

does anyone know why decals dont spawn after a certain distance away from the camera?

[maiden wadi]

@marble echo Oh. My bad again. Man I am apparently very slow today.

= needs to be reversed to <=

If the Max-Current is less than or equal to the ammo pool.

If ammo pool > 0, you have ammo to reload. So check how much ammo the magazineneeds to reload to full with Maxsize-Currentsize. Check if that's <= the currrent ammo pool. If yes use that if not use the ammo pool. Max just clamps that at above 0 just incase. After that, remove that amount from the pool and add it to the magazine.

[marble echo]

so this is all I need?

[dawn gazelle]

https://blueprintue.com/blueprint/utcluium/

[strange stream]

Hi, I'm noticing now that my inputs don't feel responsive - i know its because I subconsciously press the input before another action is done.
What is this effect called? Input queues?
Example:
Press L Mouse to attack - it does an animation and can't be pressed again untill the animation is done, but I want to be able to press L Mouse again and queue up another attack a couple of microseconds before the first one is done.

Does any of this make sense, hah

[marble echo]

Just seems to result in this for me

[dawn gazelle]

Can't be used how you're using it.

Nodes execute backwards. When you set Tiki Mag Ammo the first time, it changes the result for the Ammo Pool Pistol set. Place it into a function and feed the values into the function, then you'll get the right results.

[sand shore]

there's a proto video I made in the channel pins about how node evaluation works

it is information dense, designed to be watched until you get it, but short if you get it the first time

[marble echo]

so intead of this

its this?

[dawn gazelle]

Don't set anything in the function

The function itself will return values, you can set from them.

[marble echo]

oh I see

[sand shore]

okay this is two things.

[marble echo]

so in the BP after I set the new values to the current things?

[sand shore]

you are computing the amount to remove, then you are mutating the values.

make a function that returns the amount of ammo involved

Use the return value to increase the ammo loaded and decease the ammo pool

[gusty cypress]

Is it recommended to use level streaming for creating a loading screen? If so am I expected to have 50 levels all being streamed with the parent level being my menu???

[marble echo]

like this?

[sand shore]

@marble echo the blue area and any nodes to the left are computing the value to reload

[heady marlin]

guys anyone know how i can obtain the wolrd context object reference in my UW?

[sand shore]

Me and Datura are suggesting slightly different solves, try Dat's solution first

[marble echo]

this is what happens with it set up like that

[sand shore]

show the new graphs

everything, even if we've already seen it

[sand shore]

#umg but owning player is a world context

[sand shore]

That's the easiest way in BP

if you C++ you can just do a loading screen no matter what

[dawn gazelle]

You need to feed in the values in the inputs... So your current Ammo, your expected magazine size, and the spare ammo

[dawn gazelle]

And connect mag size in the function to where you have -7

[marble echo]

its always 7 though?

[dawn gazelle]

Doesn't matter. It's a function. It could be reused.

[marble echo]

still getting weird numbers with that stuff hooked up

[sand shore]

you're still using a lot of impure nodes @marble echo

make use of more local variables in your function

name intermediate values in the function, stuff like CurrentAmmoMinusChangeAmount

it won't matter how much you dress it up, if you keep using chains of impure nodes you're unlikely to make headway on this issue

[heady marlin]

oh really you're right....
But I don't understand why that pin appeared .. it's the first time we meet on uw

[marble echo]

alright. thanks for the help everyone

[sand shore]

@marble echo did you fix it?

[marble echo]

nah, im a first year designer, not a developer, im not sure how to use all these values and get them to play right (with hud etc)

[hoary gazelle]

Hey im having a bit of an issue if anyone could help.

Ive never actually used paper 2d in unreal, at least for long and im trying to figure out how i can stop the character sprite from rotating while im aiming with the mouse cursor.

[sand shore]

you can right click and refresh nodes, might help in a few cases

typically will fix nodes that were strange

[heady marlin]

already done few moment ago but nothing has changed

[dawn gazelle]

Works on my end...

The UI i have is just bound to the values being set in the character. No other math involved anywhere else.

[marble echo]

yeah im not sure why it doesnt on mine. maybe i have an older version

[daring vapor]

I'm looking for a way to get the base color, or the vector values of the base color from a line trace that hits a material. Is there a way to do this?

[marble echo]

ive set everything up the same lol

[dawn gazelle]

~~You must be changing some of the variables somewhere else, or they aren't set correctly in the first place.

Try with some simple numbers first - use a mag size of 10, current ammo of 10, and spare ammo of 100. Use up 10 bullets and reload. You'd expect it to go back to 10 ammo, and have 90 in reserve. If not, what were the current ammo and reserve ammo values set to after reloading?~~

I see the issue.

You have the MIN at the top plugged into Spare ammo.

The bottom pin of the MIN is supposed to be connected to the Mag Size.

[marble echo]

is this correct?

[dawn gazelle]

The left-most subtraction needs to be Magazine Size - Current Ammo

You have it opposite currently.

Rest looks ok.

[marble echo]

ah yes that's a lot more functional

although for example if I have a max mag size of 10, have 3 in the magazine and 1 remaining, it puts me up to 10 when i reload

[dawn gazelle]

Ok that is a bug with the function.

There needs to be another MIN after the first one. This one takes the MIN of the first MIN or spare ammo and that goes into the +

[marble echo]

perfect, seems to be working fine

thanks so much

[dawn gazelle]

Thanks for finding that bug 😛

https://blueprintue.com/blueprint/n2ypnyi2/

[marble echo]

lol it was the least i could do

[zenith pond]

I did this by cheating, made an atlas of averaged base colors for each material

Worked well enough for this demo https://youtu.be/sHHXiFQJZ-k

[daring vapor]

Interesting, thanx for sharing. So what do you mean by "atlas" Are you creating a texture atlas? Also are you getting the direct RGB values from the line trace?

[zenith pond]

No just getting the material and matching the material with a RGB value from a premade list

[zealous moth]

working in a team and my partner added a widget somewhere... anyway to trace it?

[last abyss]

😅 took me until now to understand, but love it thanks for this!

[river wigeon]

heya someone know why this happens? "TravelFailure: ClientTravelFailure, Reason for Failure: 'Failed to load package '/Game/Bearman/Maps/Lobbay/UEDPIE_0_Lobby_M''. Shutting down PIE."?

[north hedge]

What call is causing that?

[river wigeon]

open level

[north hedge]

Because its failing to load your Lobby Map package

Have you included a direct path to your map in the Open level or just the map name?

Try a full path if you havent

[river wigeon]

i made a asset referance for the levelm and took it from that reference

[north hedge]

Try just using a text reference?
Not sure why a direct reference in PIE would cause that

[river wigeon]

i made it that the actor i place in the world where i safe, i can choose the map asset reference because public variable maybe because i should open level first and then set variables?

[north hedge]

Try that

[river wigeon]

when i use path reference still open level by name?

[north hedge]

Failed To Load Package usually means you're referencing a package or uasset that isn't available

[river wigeon]

and there the path? i mean open level by name dont work at all for me

[north hedge]

If Open Level By Name doesn't work then that means theres an issue referencing the level you're trying to load

[river wigeon]

when i build the game, and play it not in editor, all works fine

so weird

[north hedge]

Hit File > Cook Content For Windows and see if that does anything, if that doesn't work then probably worth deleting your Binaries, Build, DerivedDataCache, Intermediate, Plugins and Saved folders and relauncing your project

[river wigeon]

thank you really much for trying to help! I appretiate it!

i try that

[river wigeon]

i would have to remake the maps right?

actors and systems i can reuse?

[sleek pecan]

Anyone have an idea about why all three of these functions would be returning null in this context? I have modified the third person template and created this new anim blue print but don't know why I can't access / find the player pawn or controller.

[supple dome]

its probably debugging the editor

use TryGetPawnOwner, it will work in game, just not in persona

[dawn gazelle]

You have to make sure you're selecting the appropriate debug object. The animBP always has a default that never returns these values.

[sleek pecan]

@supple dome I've tried it in game. Doesn't work there :/

[supple dome]

then its something else, like not actually having it assigned to the mesh component

the function does work

[north hedge]

If you're only deleting the generated folders then no you should be fine. If it fails to find it then try remake it and see if it gives you any issues

[sleek pecan]

@supple dome Figured it out finally. Since I was messing around with various examples (Third Person, Control Rig) I ended up with multiple mannequins and skeletons with the same name

that didn't end up going well, nor did an error get thrown when I had various parts of the asset chain referencing incompatible assets

[vapid ibex]

Can somebody refresh me on Modulo (%) node for integers? If I input series of integers in A "0123456789" and "6" in B, result would be "0123456 012", right? Or it will be "012345 0123"?

[dawn gazelle]

Modulo gives you the remainder of trying to divide the number. So 7%5 = 2.

10%5 = 0.

[north hedge]

So the 2nd one lol

[vapid ibex]

And with the negative values? is it -2%5 = 3?

[dawn gazelle]

The result I received was 3. So however many times 6 divides into 123456789, 3 is the remainder.

-2 is the answer. -2 cannot be evenly divided by 5.

[vapid ibex]

Sorry, that should be read as "0,1,2,3,4,5,6,7,8,9", it's ten different ints

[dawn gazelle]

oops that was %5

[vapid ibex]

I wanna make a function that always keeps the incoming int between 0 and Max value and "wraps" it around if it's bigger or smaller. So if Max is 5 and input is 6 then it should output 0, if input is 7 then it should output 1, and if input is -2 it should output 4.

[vapid ibex]

Oh

[dawn gazelle]

That's what this is supposed to do.

But if I recall correctly, it doesn't work right.

yeah, when it goes above the max, it goes to Min+1 for some reason.

negatives work ok.

[vapid ibex]

Wait I don't have an "wrap" node

[dawn gazelle]

Do it without dragging out from an integer.

and each time above the max, it adds another... so 201 results in 2

[vapid ibex]

Same thing, doesn't shows

[dawn gazelle]

Mebbe it's the wrong type of blueprint? It's part ofthe base engine.

[vapid ibex]

Well, it doesn't shows in BP for player character either

Which inherits from default pawn

[dawn gazelle]

Regardless, it's broken anyway XD

[vapid ibex]

Only God can comprehend how much do I hate this thread. It shows up in my EVERY search about some solution for a problem for UE.

[north hedge]

Yep

I see that at least once a week at this point 🙂

[dawn gazelle]

... I've never seen that one <_<;;;;;

[north hedge]

Its just Unity devs back in 2014 being like "DONT JUMP TO UNREAL!"

Also do the lazy shit I do

if(val + 1 > max)
  val = 0
else if(val -1 < 0)
  val = Max

but if there's an actual node for it, use that

[dawn gazelle]

else if(val -100053 < 0)
val = Max + 100054

?

[north hedge]

perfect

I made a random generator after we joked about that terrible BP the other day

It just randomized an int, used its result to seed and then generated another one and compared them

I also called it lazy shit for a reason lol

[vapid ibex]

I know. But this threads most often floats up in searches where I cannot find any solution, so it angers me. X)

[north hedge]

I was explaining it to Datura lol

[sand shore]

ue4 bp [topic] -unity3d bam

[vapid ibex]

Well I need something that turns sequence A to sequence B, it's for turning linear array selection into 2d array selection:

0,1,2,3,
4,5,6,7,
8,9,...

B:
0,1,2,3,
0,1,2,3,
0,1,2,3,
0,1,2,3,
0,1,...

[fiery ridge]

Does anyone know what INPUT is for "other actor" for overlapping event?

in a custom function

https://gyazo.com/083c0ea89caf4e18e32d7ab9a4b4b92b

Can I add that "other actor" in a custom function?

as a pin

[north hedge]

You'll need a Sort function, not sure if they have those in BP but google "Unreal 4 BP Sort array int"

Ignore this, reread your comment

[north hedge]

Not 100% sure what you're asking here but the OtherActor is just an AActor reference, so you can cast it to whatever you want and pass it through a custom function as an Actor reference

[fiery ridge]

https://gyazo.com/9c505c29bdf93424f2fa22d96b25f0a4

I can't find it here

[north hedge]

You can, its an Actor

[fiery ridge]

oh just "Actor"?

[spark steppe]

any ideas why my character would fall into void when i teleport my elevator around on the z-axis while the player is attached to a scene component of the Elevator Actor

shouldn't it just move with the elevator actor in that case?

[vapid ibex]

Thanks!

[north hedge]

Its an individual physics object so no, as far as I know it won't. You'll have to teleport the character as well while keeping the offset

[spark steppe]

just figured it out thanks to google, had to disable the movement component before the teleport, and turn it back on after the teleport

but who knows why, maybe it calculates velocity from the movement and applies it to the character?!

[north hedge]

I believe it does

because the character will move with the objects its standing on if they aren't static

[left niche]

Use modulo

In this case (b[i] equals a[i] % 4)

[north hedge]

Thats what they were trying to do lol

[left niche]

umm

i didnt see😐

[north hedge]

Your answer helped but their original question was how to do it via modulo

[left niche]

Can't seem to find what the problem is. Is it that modulo doesn't work with negatives in BP

[spark steppe]

oh dear... the modulo thing... even my OS calculator does return 2 for -4%3

[dawn gazelle]

Yes, that was part of the issue.

The built in wrap function doesn't work correctly either which is more along the lines of what he wanted. I sent him a function that does the math correctly.

[spark steppe]

from wikipedia When exactly one of a or n (a%n) is negative, the naive definition breaks down, and programming languages differ in how these values are defined.

[left niche]

-2 % 5 = ((-2 + 5) % 5) = 3 % 5 = 3 (-2 actually, edited)

[spark steppe]

😛

rule of thumb is to expect the unexpected when working with negative values in modulo divisions

[left niche]

yes

but it works for wrapping around though

[thin hedge]

Hi, I was wondering, is it possible to access a blueprint actor component variable from the details panel of the blueprint the actor component is placed in?

When in the blueprint, in which the actor is placed, I can access the variables.

[spark steppe]

you can get the parent actor and cast it to access the variable nvm misinterpreted your question

[thin hedge]

But how can I access those same variables over here:

[spark steppe]

all you can do is click the component in the tree view above

there you should be able to access it

[thin hedge]

Thnx Ben! Such a noob 😆

i am doing this (spawning thirdperson rifle)

on rifle blueprint i have owner no see checked

but still can see it in game

why is that?

[azure hazel]

well, i'm a newbie, but i had this problem before, what i do is strip down bp to bare essentials, make sure rifle is spawning in the first place without attaching it to character. make sure it's not a weird spawning problem, then add the other nodes one at a time. make attaching to socket last thing u do. IMHO. again, newbie.

Does anyone know how to set the draw distance of a spline mesh component? its for fencing that uses posts poles and a bar, the posts and poles are culled but the bar which follows the spline itself wont go... id have thought it would have been as easy as this https://gyazo.com/0ea62c0c1e5cb29e1e36e5e1fb185bfe but it just doesnt have the same effect as the hierarchical instances used for the posts...

[tepid marlin]

never mind, it works, its just not live and only works in play mode... just one of them strange inconsitences of unreal where a cull distance is live but a draw distance is only in play mode

[dull tree]

still dont work

any combination

ooo

i know why is not working

im dump xD

[azure hazel]

ah, good, because i was out of ideas

[dull tree]

rifle wasnt child of tprifle so it doesnt have owner no see

right now its normally works

i want to group this together, and give it a name, but i dont know how...any solutions?

[fiery swallow]

Well I mean yeah, attach a branch to Is Player Controlled, And Then connect the Radial Damage node to true

[slate hare]

how do i make a graph?

[fiery swallow]

how does the bullet detect the actor

@swift pewter

[slate hare]

forgive me if its right in front of me, but i dont see that

[fiery swallow]

Oh Radial damage damages all actors in the area

So in that case you need to filter out the bots using Ignore Actors

A way to do this is to first get all in the bots that are are in the area and then add them to an array, then connect that array to the "ignore actors" slot

[slate hare]

gotcha, thanks

[fiery swallow]

It's not expensive to get only the overlapping actors

yup

[slate hare]

it was apparently COMMENTING i wanted. thanks for the help regardless, however 🙂

[faint pasture]

You can also just do a multi sphere trace when explosion happens and that'll return the overlapped actors

then filter by class or whatever and apply dmg

[charred breach]

Hello! Please help! How can I make my resuscitation responsive? Like to work on different viewport sizes?

[faint pasture]

OR in your damage interface you can have the concept of teams so AI vs AI doesn't have friendly fire and same for Players or friendly AI

[charred breach]

Sorry for spamming but anyone knows hot to fix this 😦 And sorry again!

[charred breach]

@trim matrix Sorry! I meant responsive like when I change the viewport size ingame to stay ok and not mess up everything!

no it's not 😦

sorry

And please @trim matrix do you know how to change something in the level from UI

I made it to stay as a variable in the Game Mode

And how should I check it? I don't want to use tick because it will be memory! Or at least how to stop it?

after like 30 seconds? @trim matrix

the tick

how?

And how to not use tick? What should I use? @trim matrix

So

[summer bolt]

The executable at set needs to be plugged to return node

[summer bolt]

Also this target needs to be set

It's getting the speedometer velocity

[tired vigil]

mhm yeah u were right

i completely missed that

thank you!!! 😄

[summer bolt]

🙂 👍

[tired vigil]

have a good day!!

[summer bolt]

Glad I could help

hi, there is someone who could help me with an AI problem?I followed the tutorial but my AI controlled charachter is not moving. I've found out that it's asked to reach a point with is very far away (34028234663852885981170413848516925440.000, ....) as show in the visual logger, but in the points passed by GetRandomReachablePointRadius are rights

[fluid rover]

If someone has a moment, could they help me discover what I'm doing wrong?

I'm attempting to spawn a widget blueprint in front of my VR player pawn, however the resulting spawn is being affected by a double transform for some reason (i.e. the higher in the air I am, the further it is vertically from me, the further from Origin I am, the further it is away in that direction). Am I calling the wrong nodes to obtain this info?

(The "self actor" in question is the VR pawn's own blueprint.)

[void oyster]

Try to get transforms from the pawn component directly

[fluid rover]

@void oyster via the same GetActorLocation, just with a specified target? Or via a different BP node?

[void oyster]

I'd drag the component onto the BP grid, then extend the BP pin and get the nodes from there

Because target won't be Actor but Scene Component this time

[fluid rover]

Okay, I'll give it a go, thanks. I've got Collision, MeshComponent, VRCameraRoot, and the VRCamera object itself as far as components go.

[void oyster]

MeshComponent probably is the best one

[fluid rover]

Roger. Since I want it facing me, I'm guessing Forward Vector would be a good option?

[void oyster]

Yeah, or just the local coordinate (X by default but can be different depending on your default rotation values)

[sonic pine]

Hiho, I keep getting an error for a few days while texting my game in the UE. The error says, a function is called in the ThirdPersonCharacter BP at AddViewport ... but which function?
I do not have a function with information and I do not know which function should be used.

[maiden wadi]

@sonic pine Are you developing for a dedicated server?

Because Dedicated Servers will not create widgets. The return from that will be null.

[sonic pine]

Ah thanks that problem again ...

[tardy prawn]

Hey, all !
I have an issue
I need activate boolean variable in another blueprint (my gun), when I clicked a fire button from a my character

I try do it from cast, but i dont understand what object needs to be in cast....

What i do incorrect ?

[maiden wadi]

@tardy prawn To understand casting. Do you first understand class inheritance? How classes inherit from other classes and inherit variables and functions, etc?

[sturdy herald]

@surreal shore
It matter from which node u extract the pin, if the "Context Sensitive" its checked. Try to right click close to nodes ( not on the node) to appear the menu, and uncheck context sensitive and check if there is the node what u need or not. After this dont forget to turn back context sensitive, because it can be confused sometimes if u dont use it.

[tardy prawn]

yeah, i understand oop, i resolve this issue just now, just make "get child actor" from my bio gun
thanks )

[faint pasture]

Where would I want to put logic to make a player use a camera in world as view target? This would be for the main title screen, the player pawn will be spawned and possessed later.

[celest yacht]

Hey guys I'm stuck. I can't seem to get my actor's material to change.

I have the car windows (element #2) selected under the set material node

OMFG I DIDN'T CHANGE THE PARENT CLASS OF MY ACTOR...

[zenith pond]

Ha, I've been playing with that car model as well. Was going to use it for background animations

[cobalt gulch]

Hello

I've ran into an error message whenever i run my project

[celest yacht]

Fixed it, it wasn't that I had to reparent it. Reparenting it made it movable - which I didn't want to happen.

[cobalt gulch]

Can someone help please

[celest yacht]

The class filter from Get Overlapping actors needed to be set to none.

[celest yacht]

Are you using the same engine version?

[cobalt gulch]

Yes

[celest yacht]

Are you on the same PC?

[cobalt gulch]

Yes

[celest yacht]

hmmm

[cobalt gulch]

When I try to rebuild i get this error

[celest yacht]

toggle antivirus off?

[celest yacht]

I grabbed it from this months free marketplace assets

[flint field]

Hey, I'm new to Unreal and am a having a little issue regarding framerate and timers. At least I think that is the issue. I spawn an actor and kill its velocity after a specified time, but the time to kill velocity takes slightly longer when the framerate is lower, making the actor fly farther. I've looked into delta time and substepping stuff, but I don't really get it. Any help?

[cobalt gulch]

Like this?

or this one?

[flint field]

Such as setting a specific distance from the player?

[sullen turtle]

guys, I want to rotate my character on the character creator preview. what I wanted is to make the rotation faster based on the drag distance and direction, but I was not able to do that. anyone can help me? This is my bp right now:

[spring hollow]

Ive implemented a save/load system to my game which does work fine at the moment except i cant figure out why my character data (which are variables being stored in a struct), not load game from slot, wont load after i load into a new level.
I have the data loading tied to begin play on the player actor which does trigger again, as it should, when the level opens, it just doesnt load the saved values.

[sullen turtle]

thanks for the reply

I change to lerp but I didn't notice any changes

but my bp is not doing what I want

it's just how I manage to do something close

I can click anywhere and it will rotate based on the click position. what I would like is click in the mesh and calculate the drag and drop distance and direction to move the mesh, but I'm not sure what nodes to use to do that

actually, after a little tweak to the alpha, it is working better with lerp

thanks for the suggestion

[surreal shore]

@sturdy herald that didn't work either...

[jade rampart]

is there a fancy way to detect if player is on side or back of another character

[maiden wadi]

@jade rampart Dunno about fancy, but usually you just test their look at rotation's yaw.

[jade rampart]

you got quick example

[twilit heath]

you can just do a dot product between players forward vector and normalized vector from player to other character

[jade rampart]

Ok thanks

[summer bolt]

Is it possible to make a vehicle with just an actor and no player controllers or characters

[dawn gazelle]

Are you looking to have a controllable vehicle or one that just drives around on its own, or just stays put?

[oak relic]

Who do you know - anyone - who could help me figure out how to set up a COD Zombies style window barrier?
I'm trying to make it so an AI can walk up, tear down slats, and then climb through the window before attacking the player.

[gusty shuttle]

Quick one: Is using data tables for dialogue in a 2D game efficiant?

It seems like they run through a for loop, and if there is a metric ton of dialogue, wouldn't that be a slow operation?

[muted patrol]

hey i am having trouble with my exploding barrel blue print

[oak relic]

Thank you!

[muted patrol]

after i entering and exiting the collision sphere i still take damage can anyone help?

[void oyster]

Make sure OtherActor really is the player with a cast for example (or you can store a reference), for now you'll get damaged everytime your barrel hits an actor

[muted patrol]

yh i have just changed that but my exploding barrel still deals damage when i'm outside the area

i want to make it so the barrel will deal damage if i am inside the blast radius

[dawn gazelle]

When the player overlaps, you should store that they are in range. You may want to implement the end overlap function as well and then you can remove the reference to being in range. When going to apply damage, you check to see if the player is still in range, and only if so, apply the damage to them.

[muted patrol]

im not sure how to do all that

[hushed pewter]

@void oyster

When its collides with the middle one when at the top of the V

(Size and overlapping of other boxes dosent do anything)

But when like this it does fuck all

The middle is a copy paste of the side ones

And just has a seperate custom event at the end

(and that dosent change anything cus i tried setting it to x1 instead of x2 the different events)

[void oyster]

What's the code?

[hushed pewter]

That

[dawn gazelle]

Very basic way is to use a boolean variable. Set it true in the on overlap function, set it to false on the "End Overlap" function. You were able to get the overlap function, getting the end overlap function is the same thing. Then on the overlap function before applying damage, check to see if the boolean is true and only then apply damage.

[hushed pewter]

For both of them

Its not even them speficially

As soon as i move one of them into the middle

So the collider is touching the middle

it just DOSENT work

And destroys the ball near the top

[void oyster]

What does that custom event do?

[hushed pewter]

Just takes a score storedin the ball then either x2 or x1 based off whitch box it hits

But i tried changing it to x1 and tried moving the side ones

Either way when it interacts with the middle section it starts colliding with the balls far up

[void oyster]

Is that ball inside the box BP as well or is that just the SceneComponent sprite?

[hushed pewter]

Its its own actor that uses projectile physics

and simulated phjysics

[elfin charm]

Is it possible to detect the type of gamepad? SONY vs XBOX either C++ or BP

[deep marlin]

hey guys, do maybe someone know a good source to learn how to make a timed voting /poll system with blueprints

[void oyster]

What happens if you disable those projectiles? Are they supposed to be in there in the first place? The ball on top bounces down right?

[hushed pewter]

The shooter spawns a projectile ball whitch is its own actor

The ball uses simulate physics and projectile physics too bounce down hitting pegs and walls. the pegs use an on hit and delay event and are then destroyed

[dawn gazelle]

Just hope it doesn't return something like "Jeff".

[hushed pewter]

Wont that output xinput tho

[void oyster]

I'd try disabling the projectiles from the boxes first

Other than that it's probably code from the ball or other that's causing it

[hushed pewter]

The boxes dont ahve projectiels

[void oyster]

So that in the middle of those is just the SceneComponent sprite then?

[hushed pewter]

Balls code has nothing to do with it

They both have the same lines

that have the same end

[void oyster]

What do you mean with infinite portal anyway? Does the box in the middle keep rising as soon as it's zeroed?

[muted patrol]

i am still confuse on what i should do?

[hushed pewter]

The box in the middle rises too about the start of the V segment

about here

[void oyster]

Instantly on BeginPlay()?

[manic osprey]

Yo anyone know how i can destroy a Actor by pressing E as a Character?

[hushed pewter]

Yes

[void oyster]

Keybind Actions in Project Settings (Input), then Event On Keypress E -> DestroyActor()

[manic osprey]

It suppose to only destroy a specific Actor

[hushed pewter]

just on e press on your player controlled guy

Then destroy actor

And link the actor you wantto destroy

[void oyster]

Only on zeroed coordinates? Are physics for those disabled?

[manic osprey]

that would destroy the Character

[void oyster]

A cast could do

[hushed pewter]

Its not even 0

Its -198 as the middle

[manic osprey]

If i pick up the item the axe is suppose to disappear

[void oyster]

Then do a trace and detect collision that way, you'll get hit actors as a return reference

[void oyster]

But basically only when it's in the middle, not on the sides or somewhere else?

[hushed pewter]

nopw

Fine like this

[manic osprey]

ill be honest with u i do not know what a "trace" is. Could you demonstrate it in a Blueprint please?

[hushed pewter]

And this

[void oyster]

Pretty sure it's those walls

[hushed pewter]

but this

Breaks

[void oyster]

Scale won't matter?

[wise plinth]

How to make UE4 to update the blueprint? I updated the class Gun:
https://i.imgur.com/HIpCNIJ.png

Recompiled in UE4 Editor. Restarted the UE4 Editor but blueprint doesn't have properties FireAnimation1P and FireAnimation3P instead of previous single property FireAnimation:
https://i.imgur.com/Veq8sF4.png

[void oyster]

Maybe scale the other boxes on the sides

[muted patrol]

can anyone help me with my blueprint

[void oyster]

Search for trace in BP or look up the docs, it's in detail there

[void oyster]

I'd delete Build, Binaries & Intermediate folders, re-generate VS files and recompile

[wise plinth]

Thanks, I'm on git I'll try that now with git clean

[hushed pewter]

I

Ugh

I scaled it far down

And it seems too lwoer the threshold for death by a bit

So it seems too be expanding vertically

But only in that area

and ONLy the invisible component

Yep made the static mesh a child of it

Still invisible

so its not actually expanding properly

[void oyster]

Instead of Play, Simulate, select the Actor and watch it's behaviour

Really check that physics for that are disabled or move the walls temporarily, maybe it's those

[hushed pewter]

Scale dosent even change

[void oyster]

Something else is causing your ball death then :p

[hushed pewter]

But it cant be

since when i make the middle ones ouytput too be Sound effect 2

*2d

It plays the sound effect on collision

[manic osprey]

What Object am i suppose to add?

[hushed pewter]

Get actor of class or add that actor as a variabl

you can search for them in variables tab

[wise plinth]

It worked, thanks. It's not the first time it happened. The reason I asked is because I think one time in the past I did delete all the temporary folders I know I can delete and it still was wrong

I wonder which folder exactly causes this

Or maybe even a file

Gun.generated.h and Gun.generated.cpp in intermediate maybe? Or something?

[void oyster]

It's compiles in Build/Binaries, don't worry, welcome to the Unreal club

Glad it works :]

[manic osprey]

This wont work ffs. The item does not disappear

[void oyster]

As I said, take the time and read through the tracing documentation, will save you the headaches

[manic osprey]

where do i find this

[void oyster]

Google is the best friend (Unreal Docs)

[manic osprey]

but can u tell why the way i did it wont work?

[void oyster]

It wouldn't rely on collision sound, I'd still trace

[hushed pewter]

¯_(ツ)_/¯

Ill have a look tommorow

This shit si way too complex and cursed fo rme

[gusty cypress]

Is it better to use "event pre-construct or event construct"

[void oyster]

Casting is a whole thing of itself, you can read up on it too if you want

[manic osprey]

okay using "Actor of Class" worked perfectly fine

[void oyster]

Fair enough - you'll get it! And then you can shove it in your classmates' faces ;D

[manic osprey]

thank you

[manic osprey]

and thank you too

[void oyster]

That won't work as soon as you have more than one axe though (and the node can be expensive, so watch out)

[manic osprey]

huh okay for now its working i gotta read trought that Tracing Docs u mention earlier

[void oyster]

Depends on the use case, the nodes descriptions/docs explain what gets called when and before what

[void oyster]

It's easier than you think tbh, so dw!

[manic osprey]

you mind sending me a link to it? Dont find the exact thing i think

[gusty cypress]

Can I just think of "pre-con" as pre-loading? or will other problems come from converting my "event constructs" with "pre-constructs"

[void oyster]

As I said, depends on your use case - you need to look up the description(s) and evaluate, that way you can be 100% sure

[void oyster]

I never had to use Pre-Construct though, at least in UMG

[gusty cypress]

noted

[dawn gazelle]

Pre constructs basically can update the appearance of the widget within the editor, but it should never be populated with values that are only going to appear once the game is actually running - so like trying to grab values off a character that won't exist until runtime may cause problems.

How can i change the material of a spline?

[tired vigil]

HI GUYS

😄

oh got this loks weird

did i do anything wrong here?

im trying to make a drifting system

when it reached the allocated condition to set off the particles, it didn't expell out any particles

if you need close-ups let me know

[tired vigil]

okay lads nvm i managed to cluctch up with a bit of logic, and luck

wooo!!!

[manic osprey]

Well done!!!

[tired vigil]

oh wait

while you're here

if you can

is there a way to disable hitboxses?

[manic osprey]

what do you mean exactly?

[tired vigil]

the spheres im using to emit the particles is making the car fly

dance*

like a ballerina

[manic osprey]

Simple disable Collision

haha

[tired vigil]

uhhhhhhhhhhhhhhh

where is that 💔

[manic osprey]

do you simulate physics?

[tired vigil]

uh like

the physics tab?

[manic osprey]

Just Disable Collision

Collision Preset: None

[tired vigil]

nvm found it

ooo

thank u 😄

[manic osprey]

np

[tired vigil]

well then

then particle system doesn't work anymore

[aom

pain

off to the answerhub

[manic osprey]

did they relay on the Collision

You could set the Collison so that its only ignoring the Actor (Car)

[tired vigil]

yeah just did that

thank u ❤️

[manic osprey]

[vale ruin]

hello guys, is the blueprints documentation complete? Is there no missing info there?

I'm curious because when I search about how to learn blueprints, most of them redirect beginners to udemy/pluralsight course, etc. and not the documentations

[static charm]

documents don't teach you anything. they are mostly just a "dictionary", with only some examples/tutorials that explain things.

UE4 does have learning courses, called Academy.

[vale ruin]

I see, thank you

[steady apex]

Hi! The position of my cable attach end changes when I hit "Play". I create a bunch of cable components and connect Static Mesh Sockets with them in a construction script. They connect properly in the editor, but when I launch PIE, all the ends snap to the actor origin. Any idea what might be causing this?

[trim matrix]

so I'm having a bit of a weird issue; I have a skeletal mesh (the gun) with a couple of sockets on it. I'm trying to get the location of these sockets, and I'm drawing some debug spheres on them. It seems to be working ok, but for some reason the location of the debug spheres (and any other thing i tried visualizing them with) lags behind whenever i rotate the camera up and down. just rotating the camera side to side, things work perfectly. I suspect the pawn rotation or something might be causing this, but I have no idea why it would lead to socket world locations not being updated on a single axis.

also im using the "get all socket names" node with a for each loop, which is connected to a "get socket location" node.

[stuck hedge]

so I'm trying to test split screen 4 player and running into an issue with one controller. I have a genuine xbox controller, a knock-off xbox controller that shows up in windows as an xbox 360 controller and then a very generic knock-off Playstation controller that shows up in windows as a "generic USB controller" but the properties responds to all the sticks and buttons and what not. However, unreal doesn't seem to respond to the gamepad at all. It responds to the other two, and I've verified that it's plugged in and working, but none of the button presses or sticks seem to do anything in unreal even if the other two are unplugged. Anyone run into this before?

as you can see, windows sees it and it seems to be working.

[lofty vessel]

Is anyone know how to click and destroy mesh at the same time?

[copper pendant]

trace > hit actor > destroy actor

or click events in the player controller, destroy self on clicked object

[lofty vessel]

Can you give me the example of the bp? Im actually new here

[summer bolt]

Controllable

[dawn gazelle]

You can create it as an actor or a pawn.

[summer bolt]

Hi guys, how can I get the closest point to a mesh's surface between an actor? I know about center of mass but I need to get the closest point from a mesh's actual collision surface to the actor. Thank you!

I think the line trace hits might help but im unsure how to utilize it

nvm Im dumb I just figured out theres a getClosestPointonCollision function lol

sometimes typing out the problem helps ^^ thanks ! 👍

Does anyone know how to add an audio limiter to the master sound class?
