[dark drum]

Have you set the animation in the montage to play on the upper body slot?

[timber crystal]

Oh noooo wait wait i need to try that

[tropic pendant]

hmm alright

[dark drum]

With that reply I'm going to say you haven't lol. Open up the montage and change the slot the animation plays on.

[timber crystal]

OK thanks i dont now why but it changed back to default so that was the issue THANKS MATE!!!! :D!!!!!!!!!!

[dark drum]

As cold said, because the task finishes (finish execute) before it explodes the binding gets removed.

[tropic pendant]

..man im stupid 😭

wait

what do i do then

hold on I tried removing

the finish execute

it still doesnt work

[dark drum]

What are you wanting to happen when it explodes?

[tropic pendant]

damage the player

specifically, if the event is claled

as its claled

called*

only when it collides with the player

[dark drum]

Wouldn't that be handled in the missile itself and not the AI?

[tropic pendant]

i was debating whether to do it like that or not

wait a minute

ohhhhhhhhhh

there was no reason to do it like that

yeah I will just do it in the missile

yup worke

worked

[dark drum]

Is there a way to have child data tables (something along those lines) ? I wanting to have different sets of data tables that use the same structure for its data but want to limit selecting the datatable to only those that use that structure.

[tepid willow]

Hello, does anyone know why it's impossible to use gameplay static functions in macro libraries? I need to get game instance, but the node isn't appearing, unlike regular macros.

[earnest swan]

Maybe you're looking for composite tables? The tables you combine into a composite table would be the children

[dark drum]

That's just a way of combining multiple tables into one. In essense, i have a datatable var but I only want specific datatables to ever be selectable in it. At the moment any could be selected but if it's not specific types, the logic that uses it wouldn't work.

[dark drum]

Functions inside function/macro libraries have no concept of the world. (The same as things from uobjects) Becasuse of this they can't access stuff from it and instead need to be passed the information. If you're using C++ you can set them up to have a concept of world but it's not possible with blueprints only.

[earnest swan]

You could have your "get game instance" as an input to the static function in your library. Whenever you call it, you just pass it in from the actor using it

[earnest swan]

Maybe something like this? If I understand correctly. https://stackoverflow.com/questions/59723824/unrealengine4-restricting-datatable-pointer-to-only-use-certain-row-structure

It's a c++ solution though

[dark drum]

It sounds like what i'm looking for. I'm working on a BP only project so i might just have to live with it haha.

[tepid willow]

Oh, all right, I was thinking that it has the context since Self node can be found in the context menu

[dark drum]

Self is just a reference to itself. Unfortunately, there isn't a 'GetWorld' node in BP which would allow you to give them context to the world.

[tepid willow]

The thing is that the GetGameInstance doesn't take UWorld, but UObject, so if self is available in theory the function must be callable

UFUNCTION(BlueprintPure, Category="Game", meta=(WorldContext="WorldContextObject"))
static ENGINE_API class UGameInstance* GetGameInstance(const UObject* WorldContextObject);

[dark drum]

The way I see it is uObjects live in their own space so unless they have a direct ref to something else, they cant get it.

I would imagine there's something in Actor that gets the game instance from where it's stored which isn't available in uobjects.

[heady burrow]

Is there any plugin or setting that allows me to search for stuff in a more comprehensive way, let say, if I want to find Bind Event to On Level Loaded, if I input: "bind level" it should bring back the result?

makes sense what Im asking

[remote meteor]

a macro library's namespace is the same as whatever the object the library is parented to, if you parented it to a UObject, where it doesnt have a getworld method properly implemented, functions that require a WorldContextObject cannot work in them.

[dark drum]

Do the binocular search not find them?

[heady burrow]

dont know whats that, Im talking about right click on any blueprint for the context menu

[tepid willow]

Doesn't UObject implement GetWorld() in some way?

class UWorld* UObject::GetWorld() const
{
    if (UObject* Outer = GetOuter())
    {
        return Outer->GetWorld();
    }

#if DO_CHECK || WITH_EDITOR
    bGetWorldOverridden = false;
#endif
    return nullptr;
}

[remote meteor]

OnLevelLoaded is a delegate in a ULevelInstance, naturally it only available off a level instance

[dark drum]

Not like that but if you have an event or function you can right click on it and find references and then on the right hand side of the results is the binocular button which searches all other blueprints for where it's called.

[heady burrow]

yeah thats not what Im asking

[versed sun]

you can also type "bind level" there to find what you want

[remote meteor]

yes, but during editor, more specifically, blueprint k2 node constructions, the outer is not valid.

[dark drum]

You can modify the search terms it uses.

[heady burrow]

oh, I thought it wasnt possible since I didnt leave a space between them

because when searching for the exact terms you can do "bindevent" and it works, but "bindlevel" doesnt.

got it, thanks.

[remote meteor]

    UExtendedObject()
    {
        if (UObject* Outer = GetOuter())
        {
            World = Outer->GetWorld();
        }
    }

    virtual class UWorld* GetWorld() const override { return World; };

    UPROPERTY(Transient)
    class UWorld* World;

by shifting the world getting function to constructor, it will allow you do use WorldContextObject needed function in thus object.

[rapid helm]

does anyone know why my progress bar won't update? (ignore the turret)

[dreamy mountain]

Is there a way to make a flip flop have an A, B, and C output?

I'm trying to make a flickering light

[versed sun]

a Flip Flop Flap?

[dreamy mountain]

I've got it so that A is a permanently on, B is a flicker, and C is off

[dreamy mountain]

That's a thing?

[versed sun]

it is now

[dreamy mountain]

I thought in my head, because I'm on the bus, that's a funny name, imagine it was called that

Like prior to asking

I didn't actually think a flip flop flap would be a thing

[versed sun]

hehe

[dreamy mountain]

What about a 4 way?

[versed sun]

use a multigate

as many pins as you want

[remote meteor]

flip flop flap fluck

yeah a multigate

[dark drum]

As a guess I would say the cast is failing.

[lofty rapids]

i don't even see the bar in the picture

[rapid helm]

The cast didn't fail

[rapid helm]

it's the widget on top of the cube

[lofty rapids]

oh i c a 3d widget

never used one of those

[earnest swan]

Did you bind percent correctly in the widget?

[dreamy mountain]

Flip flop flap flep

A multigate is actually perfect for what I need

Especially the is random thing

My flip flop was literally just swap from a to b but have a delay between the two

[lofty rapids]

whats max health default value ?

[rapid helm]

both health and maxhealth at 100

[blissful grail]

It takes an object with a valid GetWorld() function defined. Because it uses said UObject to get the correct world.

[lofty rapids]

done prints ?

[dark drum]

where is the function (where the health var located) and where is it being called from?

[rapid helm]

done all prints nothing was wrong even the numbers themselves are perfectly matched

[rapid helm]

wdym?

[dark drum]

What BP is the 'Health Update' function in? Is it the same BP the function it's being called in?

[rapid helm]

OH

it's right in the pawn blueprint

for the cube itself

And Yeah

it's the same bp

[mild pine]

What causes this to happen? The variables/graphs page has been crossed out, nothing can be selected. Reopening the blueprint works fine, just curious

[remote meteor]

use breakpoint debugger(F9 on a node)

[timber crystal]

im trying to make a combo attack but my character stops his combo after first hit why?

I also added notifys

[versed sun]

annoying bug for me too

[remote meteor]

some problem with unreal slate of missing mouse up, aka reopen the bp window

[mild pine]

Oh, okay. Encountered this in 5.3? I'm in 5.1

[remote meteor]

usually happens when there is a hitch when dragging windows

been here since the early ue4 days

[mild pine]

Gotcha, doesnt occure often

Oh wow okay, havent encountered it often at all then 😆

[remote meteor]

when dragging windows, be gentle, especially if the bp is quite heavy

😅

[rapid helm]

What does that do if u don't mind me askin

[remote meteor]

when an execution is trying to run the node that has the red stop symbol, it would stop before running the node, notifying you
you can use that "breakpoint" to check for variables values, or even step the execution to see where it is going

by using this you can see what node has been executed and what did not

[rapid helm]

Oh my...

[heady burrow]

get streaming level always throws an error when I try to access it, whats exactly the package name?

I tried just the level name, the level.umap, the thing that get current level throws, etc

always an error

[dark drum]

are you actually using level streaming?

[heady burrow]

good question, I assumed the level streams by default when you open them?

[dark drum]

Level streaming is using sub levels where you load and unload parts of the map as needed.

[heady burrow]

ah, then no, I was just following the advice of someone here that told me to use that because I was trying to access actors that werent ready despite the level triggering begin

[dark drum]

It sounds like your issue is down to load order, something of which level streaming would actually make more complicated. Referencing actors in levels that will be loaded/unloaded dynamically require to use soft references for example.

[remote meteor]

what exactly is the scenario, if you dont mind repeating

[heady burrow]

I load a menu level, then load the main, when Im on begin event of main, I search for actors of class and set a variable inside PC.

if I start my game from main, its fine, but when I start from menu, the actor Im looking for doesnt exist yet

[wise patrol]

Forgive me if this is obvious, quite new to blueprints and coding in general!

What is the syntax for finding out what class the currently controlled character is?

I'm trying to switch characters gta style and having all the code in the character parent class, with four child characters. I have been able to make this code work if I copy and paste all the code separately in the child characters, but I'm unsure if it's possible to do generally in the parent class?

This is what I've got at the moment but not sure it's the way to do it

[dark drum]

why do you need to use get all actors of class? What are you getting?

[heady burrow]

Im getting a reference to an actor UI element that moves along my mouse when on a specific trace channel.

[frosty heron]

That's not how you go about it

[lunar sleet]

Casting

Don’t use == for that

[dark drum]

And where is this UI element? Is it placed in the level or spawned in?

[frosty heron]

If you want to have different behaviour between Parent and a child class, just have the same input event

so when parent press 1 -> X will happend
when child press 1 -> Y Will happend

For functions or event, you want to get fammiliar with calling super and overriding

[heady burrow]

yes, but now that you mention it, probably not the best way, maybe I should create the actor on demand

[lunar sleet]

Super in Bp? 😛

[frosty heron]

Don't know what it's called 😄

[dark drum]

That's what I was thinking. If it's follows the mouse, have the player character (or another appropriate place) spawn it when needed.

[frosty heron]

call to parent function

[lunar sleet]

Call to parent ?

[frosty heron]

yeah

[heady burrow]

yeh, I will do that.

[wise patrol]

Ah so I need to cast to the child B (in this example) and reference the self in that way?

[heady burrow]

but just to learn about it better, if I had to access an actor placed on the level, how would I go about it to know if the actor exists or not?

[frosty heron]

That's a misunderstanding of inheritance if you are trying to cast between child / parent

Lets say the parent class is called Animal, the child is called Fish

Fish it self is animal

[lunar sleet]

Yeah sorry I prly explained that wrong. I meant if you need to access an event/function from another bp, that is not inherited by the current bp, use cast. Otherwise you can call it directly

[dark drum]

It depends what you're trying to do. Sometimes I'll create an actor component that I can place on the game state that specific actors can register with. This then allows other actors to get references to them when needed.

[remote meteor]

i would probably separate the PC for menu and gameplay for starters
though they will have a base class where they can share functionality

• PC_Base
• • PC_Game
• • PC_Menu

same goes to gamemode/gamestates

[wise patrol]

Ok I see, so I'm thinking if my way is possible? I've got 4 child characters and I want to switch between them (used this video for most of the code, but it's only between two characters https://www.youtube.com/watch?v=4xo6x6mROPA&t=1287s&ab_channel=PyroDev). I have been able to alter the code so this works between all four characters, but all the code is copied and pasted for each child blueprint with the references changed respectively (using 1 to go to charA, 2 to charB etc.). Is it possible to have this general code in the parent blueprint, leaving the code empty in the child blueprints and making it tidier? Would also make it easier to change anything (eg. the speed of the camera). I thought maybe like in my picture above I press 1, check that the currently controlled character is NOT character A, then check to see if it's character B. If it is character B then run the code

[heady burrow]

you can have 2 player controllers?

[remote meteor]

different pc for different levels, achieved using different gamemode for different levels

[lunar sleet]

There’s a much easier way to do this, the check is not required

Make a function in the parent. It can be completely empty. In each child, you override it to do what you want that child to do (if it needs to be different from other children or the parent’s functionality)

[remote meteor]

also as for getting reference, probably can get them on demand instead

[lunar sleet]

At that point you just use Self if absolutely needed

[wise patrol]

Would that not just be the same as having the code in each of the child blueprints anyway? So I any changes to any variables for eg the camera would have to be done four times?

[lunar sleet]

You can also use events in the parent, then in the child use that event, make a call to parent if needed, and add the extra functionality in the execution path

[lunar sleet]

Not necessarily. You can share behaviours and variables as needed

And override variable defaults in each child

[heady burrow]

I had no idea you could do that, interesting, I thought the gamemode was unique

[lunar sleet]

So when an inherited function runs it uses the values set in that class, not the parent’s

[lunar sleet]

You’ll often see diff GMs for the game itself and the main menu for example. The Game Instance is unique, but the rest is changeable

[wise patrol]

Ahh I see, thanks very much for your help!

[remote meteor]

though they always come in a set

[heady burrow]

so the "world settings" where you set the gamemode that refers to the current level in the viewport?

[lunar sleet]

Yeah

[remote meteor]

the gamemode has to change for anything else to change

[lunar sleet]

There’s also defaults in project settings maps and modes

[heady burrow]

right

[frosty heron]

I load my save game stuff with MainMenu GameMode

once loaded -> Show Widget

like wise with other level. For Dungeon, I will have generic DungeonGameMode

It's going to handle Scores and EndLevel

[balmy niche]

dumb question, does anybody know how I would disable my sliding animation while jumping/falling?

[north bear]

Quick question, I'm pretty new to using UE but I'm wondering if there's any way I can connect the Default Pawn to my character reference in order to make my HUD target the character I'm playing as, instead of one set character.

[lunar sleet]

There’s an isFalling bool you can check on the CMC

It turns true as soon as you jump and back to false when you’ve landed

[lunar sleet]

Wdym by “make the HUD target a character?”

What are you trying to achieve

[balmy niche]

I have my Animation blueprint like this, I'm unsure of how I would get it to check for my slide animation though

and this is my char blueprints jump / slide

[lunar sleet]

You wouldn’t. You would just play a falling animation instead, afaik but I’m no #animation expert.

[north bear]

So my HUD shows different variables as progress bars(Health, Stamina, Hunger, and thirst)

Right now that character reference is set to one specific character, so the HUD will only show the stats of that character. I want the HUD to show the variables of whatever character I have selected. I know I could probably just duplicate the HUD for each character but that seems like I'd just be bloating the game unneccesarily.

[lunar sleet]

Well how are you currently getting its variables ?

And what triggers the HUD to show this stuff

[north bear]

This is how I'm getting the variables currently, it was using a cast to my character, then setting the character reference variable to that character using the output on the cast node.

The HUD shows it on Event BeginPlay

[lunar sleet]

Ok all that sounds fine but rather than doing this on begin play maybe you can use the Event OnClicked on the character class to trigger the HUD or at least to populate said variables

This way any instance or child of that character class will pull its own values

You’ll need to communicate the other way around, where you get HUD and cast into it

[remote meteor]

there is something very handy called GetOwningPlayerPawn in all UUserWidget

😄

when you add the widget, have the owning player set correctly

then you can use that

[lunar sleet]

Would HUD class actually have an owning pawn or is it the usual confusing widget for HUD class ? 😅

[remote meteor]

In AHUD, you can access controller then the pawn

[north bear]

This is a widget, if it helps

[remote meteor]

GetController()->GetControlledPawn()

[lunar sleet]

Get controlled pawn

Yeah I getcha now

I was thinking RTS like where you don’t possess one char

[remote meteor]

ah if in that case then it needs to be specific actor reference

[north bear]

yeah thats how it is at the moment.

should i create a separate HUD(widget) for each character that's added to viewport on selection of said character?

[remote meteor]

probably can use the same widget

just need to update the actor reference

[north bear]

As in, I could duplicate it and change the actor reference? or is there a way to have the game update the actor reference of the one widget depending on what character im playing as?

[remote meteor]

when you select something, i assume the event is on a controller, you can create/update existing widget to show info about the actor you have selected

the widget reference can also be in the controller too

with the widget reference then you can update the character reference on it

[north bear]

so I have a widget that's a character selection screen using buttons, when a button is clicked, it uses a possess node to use that character, and sets the default pawn class to that character using event on clicked, the HUD displays on beginplay but currently the object reference sticks to one character, whereas I want that to update to whatever character I'm possessing.

[remote meteor]

ah that explains more

then within the widget

GetOwningPlayer()->Bind on Possessed Pawn Changed

do that on construct, and also call the function with the first pawn it is currently possessing

[north bear]

so do this on the construct of the HUD widget I'm assuming?

[pallid sonnet]

Hi guys i have a question, I have a trigger box that activates a text widget, how do I make it deactivate after X seconds?

[north bear]

you could add a delay node for a few seconds, then remove from parent

i think

[north bear]

it says I can't connect the delegate in OnPawnChanged

'Delegate is not compatible with Delegate(by ref)'

sorry for the hassle btw!

[frosty heron]

Show code

[untold niche]

Question: How would I go about finding a substring and deleting it?

For example, the display name of a room I enter is called "LivingRoom.Box" and I'd like to find the ".Box" in the name and delete it so it doesn't show on the HUD

[elder lodge]

Replace

[untold niche]

Awesome, thanks.

[tall plinth]

So I'm a huge noob but I need some help. I'm trying to be able to attack while moving. So far I have it where I can play 3 animations in combo, but when I attack it makes my character stand stil.. Would anyone know how to set it up so that I can move while attacking? Not exactly sure what to do. I've created an "Attacking" state that connects to my idle/run state, but I don't know how to add transitions or coding to get it to access that state.... If anyone could help that'd be appreciated. The image included is as far as I got. I know I need to apply that to a state and have the state accessed.

[elder lodge]

try #animation

[frosty heron]

@tall plinth Why do u have a cached pose called attack?
It should be locomotion -> Slot "Upper Body" then into the Blend Posses 0

let the montage drive the attack animation

https://www.youtube.com/watch?v=ja-C9VcNyKw&ab_channel=PrismaticaDev

[lost coral]

I have a volume and I want an action to be performed as long as the player character is inside this volume, currently I see "On Component Begin Overlap" and "on Component End overlap" events but is there an event for something like "While Component is currently overlapping"?

[versed sun]

On Overlap, set a Bool to true
On End Overlap, same Bool to False
On tick, If Bool true, then [your code here]

[dark drum]

Adding to what ryck0shae said, depending on what you want to happen, a looping timer might be better. Just start the timer on overlap and stop the timer when the overlap ends.

[tall plinth]

A tutorial I'm following does this for other states and I got it to work while idling/running but I don't know how to set up the attack state that allows me to move and attack T-T I'm a noob.

[tall plinth]

My blueprints are set up completely different from this and if you're willing I'd like to DM you my blueprints/get further help! DM me if possible!

[dire frost]

^ just please dont set your timer to less than your tick rate 😭

[frosty heron]

The idle/running is your locomotion state. That's why you shouldn't need a cached attack pose(w.e that is). Let the attack montage handle the attack swing and let the locomotion drive your idle/running.

I only do DM for paid work, sorry

But what ever you need is in that video.

[boreal tangle]

Hey
I'm making a top down couch coop game.

I have a camera actor that is similar to diablo.

How do I make the camera follow the remaining player if the other has died?

What would be the best method to achieve this?

[frank sparrow]

I assume this is something I have to handle in the game instance but I’m not sure how.
I have several levels that my character can run between but when each level opens, the movement inputs don’t persist. I get its because the character is built new each level but I’m curious if there’s a simple and quick solution either with level streaming or not, to allow my movements to persist. I have 50 levels so If the answer is level streaming, how do I make that quickly? I don’t want to spend hours setting everything up again if it’s avoidable

[silver garden]

So I'm trying to do some portals stuff, but I'm having difficulties to think the math of rotating one portal's camera that renders the view into the other portal, according to the player viewing the current portal (I might've phrased that really weirdly).

I want to rotate the blue portals camera (forward blue vector) to match the rotation that the player's camera (forward black vector) based on the orange portal forward (orange vector).
The black arrow on the blue "portal" represents the desired result. Also, remember that this is also a 3D problem, not 2D

I tried doing the Dot product of Orange.Black and then the ACos of that to get the degrees.
I used said degrees to rotate the Blue vector around the Player.Up vector.

However, this didn't work.

I also tried to think the problem around Quaternions, but I couldn't get my head around it.

Any ideas?

[tall plinth]

I'd be willing to pay like 15 dollars for a runthrough within the context of my blueprints/the system I'm using if I can accomplish it. I've got a larger system going after following Gorka Games' RPG series tutorial and I'm conflicted on how I should accomplish that.

I'll try to trial and error with the information that video gives but I don't think I'll accomplish what I want because of how my stuff is setup.

[frosty heron]

It would paint a better picture if you can show how you have it set up. I might look at it tom tho, it's 5 am

Not sure if I would do any diff than how dynamic combat system in market place does it

[tall plinth]

I'll link it here, one sec.

[frosty heron]

Locomotion -> upper body slot -> blend by layer

[tall plinth]

Should I just apply all the attack anim montages to upperbody?

That should work?

then following the setup with layer blend per bone?

I'll try. DM me when you have time if you'd be willing to help me for that amount T-T

Sorry. Broke and dumb and desperate to get this understood/working.

Appreciate the video and responses already.

[frosty heron]

@tall plinth post your relevant bp, maybe someone else can take a look at it meanwhile. I will check it tom.

[tall plinth]

Gotcha. Thank you. And I'm not even sure which BP is relevant.... I'll post several.

First issue I run into is I can't even call the upperBodySlot in the anim graph T-T

[frosty heron]

The anim instance, the play montage and the montage being played.

[tall plinth]

Anim instance = anim sequence? Play montage = anim montage? and idk what you mean by the montage being played.

[frosty heron]

Anim instance == anim blueprint

Find the code in your character bp that plays the montage

Then final check is to ensure the montage being played uses the correct slot

[tall plinth]

I've tried to setup the slot and I can't even call it into the animation blue print. Should I post inside the state machine or??? Sorry sorry sorry I'm noob.

[nocturne fossil]

is there any difference between the two?

[tall plinth]

I feel dumb and I should just get direct help/handholding for this T-T

[frosty heron]

Where is the blend by layer bone?

[tall plinth]

I can call that in the abp but I can't call the upperbodyslot

and don't know what i'd plug into it anyways

because I have 3 animations with an attack combo

is that even where i'd do it?

[frosty heron]

Yeah but u need to cache your locomotion pose

[tall plinth]

wouldn't i also need to create an attacking state inside the main state machine?

cache when where

[frosty heron]

Ur state machine is your locomotion (idle or running )

Attack is handled by montage

So while u move around as usual. When you left click, you can swing your sword (while the leg move as usual)

[tall plinth]

i have that set up in a blueprint separate from all of this and i'm not sure how to call on all of them or what i should do.. hold up i have a little video of it

[frosty heron]

Do u watch YouTube tutorials?

[tall plinth]

yep

[frosty heron]

Not a setup that I will use

[tall plinth]

other tutorials either leave me clueless or dont have as many features as i want to implement

and even the one i'm following i'm cutting out a lot of stuff

[frosty heron]

I would delete that "combo" system anyway tbh. Not scaleable

My learning come from dynamic combat system in market place

Have proper use of input buffer

[tall plinth]

i aim to make a simple adventure rpg so i dont plan on doing too much besides having a melee and a ranged weapon T-T

[frosty heron]

What UE project do you use?

Version*

[tall plinth]

what do you mean? oh 5.3 or whatever the newer/newest one is

[frosty heron]

How big is the file?

[tall plinth]

5.3.1

let me check

entire folder is 681mb rn

project file is 287 bytes

[frosty heron]

Upload it and dm me the link, I will take a look tom.

Google drive preferably

[tribal gazelle]

Can badly optimized blueprint code affect your frame rate?

[tall plinth]

The entire folder or just the project?

entire folder i assume

[frosty heron]

I don't need intermediate, binaries but if it's 600 mb just the entire folder is fine

[tall plinth]

doing it now! thank you!

[naive stream]

Just in case someone finds this useful here is a small useful blueprint function library node: Toggle Bool
See the code for it (expanding with more over time) here https://github.com/RancorousGames/RancUtilities/blob/ec652ca42a5d390659fa178e604027916c2a68f6/Source/RancUtilities/Private/RancUtilityLibrary.cpp
(will add packaged version in the future)

[crisp gulch]

I can't get it to fire a hit event. Could someone help me figure out what I'm doing wrong?

[lunar sleet]

Bad collision settings is usually the culprit

Make sure both objects are set to block each other

Might also need to enable generate hit events iirc

[pallid nest]

any ideas why my trigger box is NOT working in a specific place in my map? it was working fine earlier but I must done something that now is not and it only works when I move it to a different place, a bit odd?

[frosty mural]

Mmm, why isn't my widget being removed?

Nvm, seems to be an instance issue, only A is being run

[grizzled ruin]

Hi all, im trying to LoadAsset in an editor utility widget to load my GameMode asset and set a FName on it, for some reason the cast always fails, if I print out the name of the object returned, it is the correct name, but for some reason I can't cast it, any ideas what's wrong?

(the asset path is obtained from right clicking and Copy Reference on the asset)

I tried to have a GameMode field but it seems like for some reason I cannot assign it a value either, Im assuming those are somehow connected and its something to do with the fact im trying to reference a GameMode. I've used LoadAsset successfully in other places with different asset types fine

[lunar sleet]

Maybe you’re looking for #editor-scripting

[grizzled ruin]

I got around it by storing the FName in a data asset file, and then I loaded that with LoadAsset and it was fine. Weird behavior

[lunar sleet]

I’ve not seen cast used like that before tho it makes sense ig

[unique silo]

how can I access the point of view from a camera that is in a different blueprint? Im trying to make a first person view from a camera that is attached to a socket on the weapon blueprint. But I am calling it from my character blueprint. The casts succeeds, and I also set inactive the current character camera, but I dont know how to "switch" the view to the camera on the weapon?

[fiery swallow]

you can see through difference cameras with set view blend target

set view target with blend

[unique silo]

thanks for the reply. Would that work though ? since the target is player controller and not Lyra player controller?

nevermind, I can change the target

the problem is though, that view target with blend expects a new actor object target, where in my case the camera on the rifle is a component

[mild glen]

how do you make a script that moves a mesh

[fiery swallow]

if it has a camera, and the client is aware of the camera's existence, view target with blend will work

are you saying that..

the gun is already attached to the pawn you're using?

[rapid helm]

does anyone know why the healthbar (it's a 3d object) only updates when the value is in between 27-75? (the health & maxhealth at 100, printed the values of the percentage and it is exactly what it should be (ex. 80 = 0.8), the widget is a progress bar)

[unique silo]

thanks, it actually worked by just connecting the object, not the camera. But yes, the rifle actor gets attached to the player actor at runtime

seems I have a new issue now. Since the camera is on an actor that is not a pawn, It cant be controlled with pawn rotation.....

[radiant cape]

I am trying to use the "create event" function to bind a delegate to a function I have in my class but it won't show in the list of functions if I give the one i'm trying to call an input.
I was able to do this in another class but applying the same technique won't work in this one.

In the past i'm pretty sure deleting the node and adding it back in worked but not this time

if I use the create event node to make a custom function, then add the desired input it will give this error

if i try to use the node to find the function with the input it wont show

i've got a deletgate or whatever calling a function with an input in another class and it's working fine, i don't know what i'm doing differently :/

[dawn gazelle]

The delegate binding can only bind to an event/function that has the same inputs that are declared on the event dispatcher.

[radiant cape]

well ok i thought i already did that bahaha tyty i'll make sure to check next time

[kind estuary]

how do i make pawn sensing not detect on tick

so just make it check every 3 seconds, for better performance too

[dawn gazelle]

Turn down the tick rate on the pawn sensing component to 3?

[kind estuary]

tick interval

i changed it before to 10

didnt do anything

it still detects as soon as you get close to the enemy

[lunar sleet]

Pawn sensing was replaced by the #gameplay-ai perception system.

And it usually doesn’t need optimization, did profiling show that your pawn sensing is what’s slowing down your game? @kind estuary because if not, premature optimization is a bad idea

[kind estuary]

ah

didnt know that

yeah its premature. but since i dont need it to be detecting always, and i actually need some delay in the detection

i can tell this is checking if it has actors around on tick

or wait maybe not, maybe its just a collision

[lost coral]

But it seems "On Begin Overlap" doesn't trigger if the player spawns inside the volume, the player needs to be outside it and enter it for the event to trigger. Any way around that?

[dark drum]

OnBeginPlay, get overlapping actors. If there's valid characters inside, do what you would normally do on overlap. You might might need to add a delay until next tick node before it does the check to make sure everything has loaded.

[dark drum]

How is your widget setup?

[dark drum]

The target would be the actor with the camera in it, in this case the rifle. AFIK the set view target with blend will find the first camera component in the specified actor and set it as the view target.

[random pulsar]

hey guys i made a tile and spawn it correctly and i want to make in this tile a navmesh for ai is it possible to make this?

[paper pond]

I rembemer being able to uncook a mesh and open it up in editor, changing it's materials collison etc. However when I try to run the uncook editor utility blueprint it crashes unreal engine.

This all started after I had deleted, added stuff to the content in windows. I suppose causing some desynch. Then i started having corrupt fbx crashes, not being able to see uassets in the engine, tangent errors, smoothing errors, failed imports.

I have tried reinstalling UE several times, different versions, wtf is going on?

[versed sun]

after Begin play (Delay Until Next Tick), you can check for Actors overlapping the Component @lost coral

[dark drum]

I'd give it a 8/10

[dark drum]

You need to make the navmesh dynamic so it'll update when you make changes at runtime.

[proven karma]

Looking for some pointers. Have a PickUp BP with a static mesh, dynamic material and 2 description text variables, all of which are instance editable. When player interacts, those variables are passed to the player along with the PickUp BP class and transform via interface, then PickUp BP is destroyed. The static mesh being used by PickUp BP is set to a SM component in front of the player, which is then made visible. Player can examine the mesh. When the player next presses the interact input, that mesh is hidden and the original variables are used on a new spawn instance of PickUp BP, so it’s the same , when it’s put back down, as the one picked up. I’m casting the newly spawned instance to PickUp BP to access the variables and set them from the ones stored in the player. But that’s not happening. It’s spawning the default PickUp BP mesh and material. When I interact with that new instance , it just disappears. PickUp BP is tagged as ‘examinable’ and this is checked to differentiate between non-examinable actors. Hope this makes sense. Also to mention that line trace is used for player interaction.

[brazen pike]

How are the variables being used inside the Pickup bp? Is it using them on begin play to set the mesh and material and stuff?

[proven karma]

Originally it was in construction script, but I moved it to BeginPlay to see if that changed anything

[brazen pike]

If youre changing the variables after the object has been created, then the default variables will be used.

[proven karma]

So I can’t grab a reference to the newly spawned PickUp, then cast it and set the variables? It would be easier to not destroy the original since this is just an inspect mechanic, but I’d like to figure it out anyway

[versed sun]

Hide it / set visible to false ?

[brazen pike]

You can set the variables you need to change to be "Expose On Spawn" as true. Then when you create the object, you'll see exposed pins for the variables you want to change. That will let you change the variables before it has been created

[brazen pike]

Honestly this will be easier, but if it needs to be destroyed for some reason that's probably why

[proven karma]

Expose on Spawn - thank you. I probably will @versed sun just hide it as it’s simpler. But to satisfy curiosity I’ll try and make this process work first.

[chrome pumice]

Yo guys quick question, im trying to bring root motion into my game but for some reason whenever the animation ends my character kinda tilts like the mesh and stays there, it adds more rotation the more often i play the animation, is there any way to reset the rotation after the animation has finished?

[pallid nest]

hey guys good morning, I am trying to get three booleans from three different blueprints (sender) and then a trigger box (receiver) on overlap check if these three conditions are meet (with branch?) something occurs. I understand casting is not effective to do this for a variety of reason so I am trying to learn and understand interfaces. I watched so many tutorials on interfaces and while I understand the concept of transfering the information I don't know how to apply to this scenario (3 blueprints with three different booleans send to trigger box). Any ideas please?

[hidden shard]

Hello.
I am currently struggling to figure out the best way to set up a blue print. (e.g. how to use "cast to" as little as possible)
Does anyone know of any books where I can learn about these designs?

[thin panther]

Using cast to as little as possible doesn't mean you're setting up a blueprint right.

Often times it means you're doing convoluted hacks to work arpund a cast, with methods that still incur the potential cost of them, which is the wrong way to set up blueprints

[hidden shard]

Thanks for the reply.
I'd like to know if there are any other books you'd recommend, because I'd like to learn more about creating a well-designed project, besides "cast to."

[thin panther]

Unfortunately unreal moves too quickly for books, so any material you buy would be already outdated

[hidden shard]

Moving fast is not much of a problem.
We want to know how to design and manage the design and its management in a way that is easy for third parties to understand.

[thin panther]

It is a problem, when because of it, no one makes good books :P

There aren't good unreal books

[dark drum]

General programming concepts regarding hierarchy I would say. I don't know any as I haven't read any but as a topic, it's a bit more transferable.

[thin panther]

Most of unreal design is just being sensible with OOP though.

Try to design modularly, and be data oriented, as opposed to hard coding things. Use casts when you have an established hierarchy, and sensible inheritance chain. Use interfaces for class agnostic behaviour, and use components for plug and play modular behaviour, like a health component etc.

Don't do silly things like including assets in base classes, as then you incur huge memory penalties for casting to unloaded classes

[dark drum]

Regarding not casting, it's miss understood. The reason people say to avoid casting is to prevent an asset load chain where just loading one asset forces everything in your project to also be loaded. If the thing your casting to is going to be loaded anyway (such as Pawn/Character and PlayerController) it doesn't make any difference.

[thin panther]

Basically, pretty standard stuff for other engines

[chrome pumice]

does anyone know how to fix this?

the wrong direction is a skeleton problem and i can fix this with bp but the way he is leaning more and more after every animation is the main problem

[thin panther]

And even when it isn't guaranteed, proper base classes mean you are only loading kilobytes, which is nothing.

[dark drum]

That looks like your animation is moving along the wrong axis in the animation. Forward is normally positive X so if your root motion isn't moving along this axis it'll look like what you show in the video.

[thin panther]

And another big thing is to not be scared of c++.

You want to be using it for anything you plan to ship, even if it's just for your structs and enums.

[chrome pumice]

yeah i know i just need to rotate the animation for this but the way the enemy is just tilting is wierd

[hidden shard]

I asked the question in the sense that I would like to have a book where I can learn how to create such appropriate classes.
Are you saying that the only way to do this is to gain experience?

[thin panther]

Pretty much, or different online resources can help. Unfortunately having the intuition to know when to use what is only with experience

You'll start to gain a Spidey sense of sorts

[dark drum]

You can learn the concept which would only take half hour (if that) but as every situation is different there isn't a one fit rule for all.

[thin panther]

Picking up some resources on basic object oriented architecture will help a ton, and learning what things like data driven design are can as well. But after that it's pretty much practice makes perfect

[dark drum]

Making something that doesn't work well is the best way to learn as you start to understand why what you did doesn't work well in the situation you made it for.

[hidden shard]

The function itself does work, but there are times when I sometimes wonder if it is optimal. This is because the blueprints become more complex and harder to see.

[dark drum]

A good project for getting a good sense of this is an item/inventory system. That's what really made me understand and appreciate good hierarchy.

[hidden shard]

I also wonder if we're going too far because we don't know useful nodes like APPLY Damage and BPinterface.

[dark drum]

Make sure your breaking your logic down into functions. Especially for logic that is repeated.

[thin panther]

Optimal and blueprints are a bit of a misnomer.

If it's not causing you issues in the profiler, and it isn't obviously awkward then it's probably fine, until you may stumble on something that reveals it isn't.

A key thing is to be DRY. Don't repeat yourself

But it's natural to finish implementing X and then realise it exists already. It's part of learning.

[dark drum]

definitly this. UE has a lot of hidden features lol.

[hidden shard]

Yes, for example, when there are several enemy characters to judge, it would be easier to implement using BPinterface than repeatedly casting each and every enemy character to judge. That is the kind of knowledge I want.

[thin panther]

You see, that's where learning about general OOP helps. You could just have a base class for your enemy, and cast to that

My honest advice is to tackle basic programming principles in an object oriented language. You'll do yourself some favours in unreal, after that, it's just experience really.

Looking around the pins of the channels have some useful info too.

Like this one has a video pinned about blueprint communication

[dark drum]

This, I can't even write C++, whilst I can read bits, the concepts help massively in blueprints. Insert learn C++ comments haha

[thin panther]

Hell I was staunchly bp only for ages. Learned about c++ structs in unreal, and kicked myself for not knowing it sooner. Now I rarely touch a BP node, if at all

(for major things)

C# is great, it has interfaces too :D

[hidden shard]

Encapsulation, polymorphism, inheritance
These have snapped my heart to pieces. ；；

[thin panther]

And they're real interfaces instead of unreals ungodly hack

[thin panther]

Unfortunately they're a necessity

They will click one day, and you'll wonder why you ever struggled

(Been there, done that)

[hidden shard]

What did you guys learn C++ from?
I'd love to know if you can.

I've only touched JavaScript at work.

[dark drum]

As bizarre as it sounds, have a dig through minecraft source code. Yes it's java but having a dig through that helped give me a good idea for structuring classes.

[thin panther]

My primary knowledge came from bits and pieces online, as well as the cpp reference. After that I jumped headfirst into sfml, only allowing myself to use the documentation as a reference.

Did some work in directx, because of uni, and then had some fun in unreal. A very convoluted path. I tend to reccomend people go to learncpp.cok instead, and pick up a C++ book if you're really interested in it (like for the industry)

Though I would say if you don't want to use it in industry, learn the concepts with a friendly language like c#, and then gain a working knowledge of c++, to use in unreal, when that interests you

[hidden shard]

Thank you.
I knew I would have to learn C++ eventually if I was going to touch UnrealEngine, so I'll give it a try this time around.

[thin panther]

Don't get burned out by it. You'd be surprised how much good knowledge of BP, with just some basic programming concepts can take you

Though it's not as bad as everyone pretends

In unreal at least :P

[amber spindle]

Hey I am having problem with Launch Character. My player can walk on walls. When walking I use launch character blueprint to jump and negative direction to go back to wall. But there is a problem that if player is standing still and jump somewhy it rotates. I even tried setting rotation and giving it back after launch but it still doesnt work. I am adding video of slowmo

All jumping part looks like this

[naive stream]

as long as you learn C++11 or newer you'd be fine

[naive stream]

What you need to do it to test LaunchCharacter in a simpler environment. I looked at the source code and it doesn't seem to do anything other than add velocity and set airborne

Try calling LaunchCharacter with a default ThirdPersonCharacter blueprint. If that works fine try to figure out the difference between your char and that default char

[amber spindle]

I found out that somewhy I get launched not only on x axis (how should be) but Z axis aswell. I think of this small velocity makes player turn into z axis change. Image: Green - start location, Blue - velocity after 0.1 sec launching player, Red - location after landing

[versed sun]

isn't there a 'Character faces velocity' checkbox or something ?

in Character class defaults

[amber spindle]

I unbox it but everything looks the same

[versed sun]

bummer

[amber spindle]

ye :/

I don't get how it launches player into Z axis if I only input X axis velocity

[amber spindle]

I noticed it changed my normal walking it wont change orientation while on ground. I think it's because while on wall my character is on flying mode

[heavy lion]

I'm second guessing myself.
I am working on a bed which saves and advances time, and alters player stats.
It calls lots of functions from other classes. And the only way I can think of doing that is casting.
Is there a better way?

I dont think an interface applies here, because i dont need two classes to implement a function in the same way.

And an event dispatcher doesnt make sense as I would need to cast to that class anyway right?

For example. When I interact with the bed, I call a function "AdvanceTime" in the game mode. But I also call "SaveGame" from the GameInstance.
And finally, I update stats on the PlayerCharacter.

Thats 3 casts for a bed

[brazen pike]

What is it about casts that you're worried about?

[heavy lion]

Well, people say you should try to avoid them. I am just wondering if I need to avoid them in this instance.
I cast to like 3 other actors from the bed actor.
Doesnt that pull all their functionality into this one class?

[vapid grotto]

how to attach cloth to shoulder of charactter rigs and add simulation on cloth in ue5

[frosty heron]

You should not avoid cast, in many cases they are not even avoidable

[heavy lion]

Thats what I was thinking.

[frosty heron]

Doing cast will produce hard reference, that will load them to memory

That's just the cost of using blueprint

[brazen pike]

it probably doesn't matter too much in your case. Usually if I avoid casting, it's because I'm trying to limit memory usage. Every time you cast you load what you're casting to into memory, but in your case (the player character, gamemode and gameinstance) it doesn't matter because those things are already loaded into memory anyway

[frosty heron]

In cpp land it will not load the object to memory

Yeah well if you have hard ref everywhere, you might load the entire game just by loading your character

[heavy lion]

This is what I needed to hear.
Thanks @brazen pike + @frosty heron

[frosty heron]

It's not the casting is the problem but the hard ref in bp. If you want to optimise then use soft references

It's kinda mandatory to use soft ref, especially if u have data table

Data table with hard ref = rip

[brazen pike]

Yeah you really only need to worry about it if you're doing it in the other direction. For instance, if you cast to the bed from your character. That'd cause the bed to be loaded whenever the character is loaded.

[heavy lion]

That makes a lot of sense.

[brazen pike]

I ended up needing to use hard refs. Turns out there's a bug in UE4 that can create missing netguid cache entries through seamless travel if you use soft references. Screwed me over since a decision was made to not upgrade to 5

but yeah, look into soft refs

[frosty heron]

I'm not sure, also i don't seamless travel yet so I hope I don't run to what u got 🐱

@brazen pike u are doing multiplayer?

[brazen pike]

yeah it only happened for clients

[frosty heron]

Ahh ok

I will keep a look out

[brazen pike]

are you in UE5, if so there's a super easy fix. But if not then source code editing is the only fix (if you HAVE to use soft references, otherwise like me just switch to hards)

[frosty heron]

I'm in 5.1

Got like 400 items to load, I can't hard ref them 😄

[brazen pike]

then you don't have to worry about it. Go nuts with soft refs

[brazen pike]

damn that's gotta be awful to work with

[frosty heron]

The system is done , rest is just adding to data table

[amber spindle]

I found out its because of gravity. While I am on the wall and launch character in x axis, gravity adds on z axis and there is z velocity what makes player turn. Maybe someone could help to figure out how turn on and off gravity inside blueprints?

or maybe how I can edit movement mode (flying) so this mode wouldn't have gravity?

[proper vigil]

Duplicated this MetaHuman code to run different dialogue when the Objective Text is something different. Different vars and a different new text for the Objective after the second event run. The one that says Test Text is the second one and the one that is first has the text change to Visit Cemetery. For some reason, they both result in the objective becoming Test Text.

Other image but with the other variables.

[dark drum]

You should check this out if your needing a dialogue system.

https://youtu.be/88xikHeYQDA

[proper vigil]

I already have a good dialogue system, just one issue.

[indigo bough]

Hey, so I've tried both methods of adding a new row to a data table in an editor utility widget, but I'm getting this warning when trying to run the event. Any help would be very appreciated 🙂

[frosty heron]

Are you feeding the right struct to the data table?

[indigo bough]

I feel like I am. It's a custom struct which was made for this DT 😬

As you can see above, the same struct is used for the row structure of the DT

There is only the one struct with this name:

This is the whole thing:

[frosty heron]

Hmm im not sure, maybe try to pass a value instead of a ref?

After you set member

Get the Struct ref then break it

[indigo bough]

Yeah, I tried with the "Make S_WorldBookmark" instead of "Set members ..." but it seems to have the same issue regardless of whether it's a ref or value

[frosty heron]

then make then plug it? I dunnoe

[indigo bough]

I tried this

No different

(missing other inputs in this image, but yeah)

[frosty heron]

is your struct declared in CPP? if it is, does it derived from FTableRowBase?

that's my last guess

[indigo bough]

Made in Blueprint

[dark drum]

If you're having to copy and paste/duplicate the entire thing, I wouldn't call it a system. Either way, with what you've shown it'll be difficult to say what the cause of the issue is. Most people wont take the time to figure out what the spaghetti does. If it's saying some test text it would be a case it's not being updated so you'll need to work backwards to debug the issue.

[frosty heron]

Im out of idea then 😔

[proper vigil]

After the first event, the objective text should be "Visit Cemetery" but it just becomes "Test Text".

[indigo bough]

No problem, thanks for trying 😄

[versed sun]

did you try to manually set the DT with the drop down ?

If the Data Table pin is a Copy of your Ref , then it would be saving to a copy ?

[indigo bough]

LogScript: Warning: The data table type is incompatible with the RowData parameter.

[versed sun]

yah , like that , same thing ?

hmmph

[indigo bough]

Very confused 😄

It's a new struct, DT and blueprint

[versed sun]

unplug row data , and compile

[dark drum]

where is event talk and event talk 2 called?

[proper vigil]

A BPI.

[indigo bough]

I don't understand why it's defaulting to a wildcard input on that node in the first place

Surely it should set the input to whatever the valid struct is

[versed sun]

even after compile?

[indigo bough]

It's not just that node either, with a new AddDataTableRow node it does the same thing

Must be a 5.3 bug?

Find that hard to believe though

Might just store this stuff in a DataAsset array variable instead at this point 🤣

[dark drum]

That doesn't answer the question.

[proper vigil]

Oh, called, not created.

[dark drum]

That still doesn't answer the question. You've already shown the events. I need to know how/where they are being called.

[proper vigil]

They aren't in the BP any other times.

[heady burrow]

Nitpicky question, Im setting the location of an actor, and when I see the actor get there it feels like it does it in a "elastic" fashion, meaning, there is 1 frame that it appears half the actor occupies a place that is a bit further away then goes back to the proper location.

Any ideas I could look at to find out whys that

[heady burrow]

I tried that

[indigo bough]

Should usually solve that

Ahh

[heady burrow]

Im setting the position using a gridsnap

might be related to that but unsure how

[indigo bough]

Shouldn't be an issue, the output location is still a valid vector so that's all the Set node will care about

[dark drum]

Events don't call themselves so I guess I can't help you any further.

[heady burrow]

I tried using interpolation, and I noticed when I raise the speed past 5k I get the same effect

[indigo bough]

Are you running this in some kind of multiplayer situation?

[proper vigil]

They are interfaces and when I try to drag them it since not BP callable.

[heady burrow]

no, locally, I use a trace channel to get the position, a gridsnap and I run settter on tick

[proper vigil]

Oh, I think you mean this.

In the first character BP.

[indigo bough]

Hmm, why on tick? Is it something that needs to happen every tick? Can you not run it once, or based on each time the line trace fires?

[heady burrow]

ah, no, my actor is just a static mesh basically.

[dark drum]

So there's your issue, your progressing both conversations at the same time.

[heady burrow]

just a simple empty actor with a cube in it

just moving the white thing accroos the grass

[indigo bough]

You don't want to be setting your actor's location every tick, try setting it using an event only when you need it to move

[heady burrow]

in a tiled fashion

[heady burrow]

that makes sense, using set on tick felt weird, so I should detect when is needed to change positions, and set it once

[indigo bough]

Yep 🙂

That's probably the cause, I mean it feels like it might be anyway

[heady burrow]

thats how I had it on my older prototype using another language

[proper vigil]

Do I need to duplicate the code but replace talk with talk 2?

[heady burrow]

still not sure what could cause the bouncy effect

[indigo bough]

Well if you're setting the actors location every tick it's possibly just struggling to do it that quickly or something, so it's rubber-banding back to world 0,0,0 or something like that

To be honest, it probably should be fine, but it's the first thing I'd suggest changing anyway as it's just bad form to use tick for stuff like that

[heady burrow]

yeh definitely, thanks

[dark drum]

If you feel like you need to 'duplicate' large amounts of logic, you need to think of a different way to handle it.

What if you need to add 2 more conversations? What about 10 more? what would you do then?

[proper vigil]

I mean the code in first person BP.

[dark drum]

You could put a bandaid on it and do a check for which dialogue it should be progressing but either way, when you want to add more, it's just going to get messy and very buggy.

[proper vigil]

Yeah I'm gonna try to do a better solution. All I know is that it can stay in the first character BP.

[dark drum]

take a look at the video I shared. It'll put you in the right direction. 😉 It'll make having multiple conversations with different NPC's a breeze.

[high ocean]

I have a weird problem: I have a little game where you can program a robot to do stuff. It's all good until you program it into an infinite loop (which obviously crashes the app). How would I go about allowing the player to make the mistake of programming it in such a way but not crash the program & just display a warning in the app instead. I'm using a bunch of recursive calls to list up registered actions for the robot, but the problem is as soon as the engine detects it, it straight up crashes, so (at least in blueprints) I don't get a chance to break out if the counter goes above a certain increment.

for reference:

this would crash because sequence 2 (purple) calls seq 1 and vice-versa

but I want the player to be able to actually allocate those as they are (wrong)

[dark drum]

Every action the robot does, it increases a counter, when it reached it's limit it stops and give the player a warning. The counter would be reset after tick.

[frosty heron]

Just add condition?

SEq 1 -> Condition (Counter can go here) -> Seq 2

Iff condition is not met don't go to Seq 2

[high ocean]

it seems to crash before reaching my counters in bps

[frosty heron]

EG if the counter goes more than the limit

What's ur counter?

U can set it in Project setting

[high ocean]

it's what I've tried already @frosty heron. It never reaches the counter, it crashes at function input

[frosty heron]

You add a branch?

[high ocean]

so it's probably a check in the codebase that doesn't even allow it to call the function somehow

[frosty heron]

show your code

[dark drum]

unless all the actions are being done in a single tick it shouldn't trigger the loop detection. You could make it so it only ever performs at most one action per tick.

[brazen pike]

You could force every function the player can make to be slightly latent (by at least 1 frame, but I'd probs recommend 0.1s), that way they can't write code that'll make an infinite loop, then you can add a counter anyway and check

[high ocean]

it's kinda hard to follow along but this function is re-called

& the counter never actually increases, the engine breaks out and lists callstack before ever increasing the counter

[high ocean]

🤔 maybe that's not a bad idea actually...

[dark drum]

Also, the robot only ever needs to know about it's current action and possibly the next one. It looks like your trying to get all the actions at once.

[brazen pike]

you probably wouldn't want players to be able to write code that's too powerful anyway. They might get carried away and crash the game by making something extremely complicated that is looped 100000 times in a single frame, so 1 action per frame will stop them

[high ocean]

actually no, it's more complicated than that. I need to pre-load all actions, first to last

[dark drum]

why?

[crisp gulch]

I know this is probably a silly issue, but I'm trying to implement a projectile into my project and it never calls On Component Hit (StaticMesh). Everything I see about this issue is telling me to check the collision is blocking, and that Simulation Generates Hit Events is set to true under both meshes collision tab.

Could someone please assist me in figuring out what I've missed?

[high ocean]

@dark drumsry, just too much to explain. I have a level generator in place too, so it also checks for valid run bla bla...

then I use the same system for actual action to keep the code light etc etc

[versed sun]

while preloading , keep an Int Var counting each step, when over 1000, stop loading and error out

[brazen pike]

does your static mesh in the projectile bp also have all the same settings?

[crisp gulch]

Yes, I belive so. Does this look correct?

[amber spindle]

Ye it worked, no more doing down (to gravity axis) but now some random glitches happenning maybe have an idea how to fix?

[frosty heron]

Those delays man

[amber spindle]

ye, I will make it better now it's for testing 😄

[frosty heron]

well not a good test if it's the one responsible to screw things up

but anyway I can't tell

[brazen pike]

Does it actually have a collision mesh? What is the static mesh, is it a custom model or something made from the starter content

[crisp gulch]

I think it does have a collision mesh. It's a custom model, but I had originally used a regular sphere primitive, but that didn't work either.

[brazen pike]

how are you moving the projectile, are you using the projectile movement component?

[crisp gulch]

Yep

[brazen pike]

do you have "sweep collision" enabled under "projectile simulation"?

[crisp gulch]

Yeah

[crisp gulch]

Should it be disabled?

[kind estuary]

Im hitting a vehicle with rocket, how do i make a vehicle move into the air as its hit by a rocket
Add impulse doesnt work
Launch doesnt work

just need it to jump into the air

but dont seem that there is such a option with vehicle movement

[lyric quiver]

How can I constrain the movement of an actor in bp? There is the set constraint mode but I don't see a mode that is all planes.

also for set linear limits idk what to put for accessor

[brazen pike]

@crisp gulch Okay, take your static mesh in the projectile's BP hierarchy, and drag and drop it over the defaultSceneRoot

should fix

apparently hit component doesn't work if there is a default scene root

[crisp gulch]

That works! Thank you! I wonder why default scene root keeps that from working.

[brazen pike]

yeah, so the projectile movement component will only affect the root component. So you need to make sure whatever the root component is has all the physics set up (like having collision, and simulating hit events). The static mesh was also moving because it is a child of your root component, but wasn't using its physics

[sour crater]

I have a error going on im tired of trying to figure out. Can i get some help?

asking so i dont interupt anyone really ^^;

[brazen pike]

Just post it and if anyone can help they will

[crisp gulch]

Have you tired using Add Radial Force? It was the first thing I could find

[dark drum]

Don't ask to ask for help, just ask. 🙂

[sour crater]

So i have the resource component inside my BP_PlayerCharacter, but it says it does not inherit it

[dark drum]

Pull from the blue pin on your first cast can get the component.

[brazen pike]

In that situation you don't want to cast to it. You're currently asking the engine "hey, is this BP_PlayerCharacter a ResourceComponent?" but it's not a resource component. You want to get the resource component from the player character instead. The first cast (to your character) gives you access, so now you can drag off the blue pin and search for the component

[sour crater]

thank you guys

[crisp gulch]

By constrain the movement, do you mean like keeping the actor from going too far in one direction?

[sour crater]

Gets 50 can not read errors.

;w;

[crisp gulch]

Could you post a screenshot of the error

[brazen pike]

Have you added a resource component to your player character?

[sour crater]

yes

[lyric quiver]

I want to freeze the actor in a specific location

[kind estuary]

didnt get it to work, but the Set Linear Physics Velocity is super juicy

[brazen pike]

Click on "Get BP" in this error here, and it;ll take you to the problem

[sour crater]

okay let me see

it took me back to the error i just fixed

[crisp gulch]

Oh, so like stopping them in place when certain conditions are met? Like, actor has stepped in a bear trap, constrain them from walking for 15 seconds.

[lyric quiver]

Something like that yh

[crisp gulch]

Okay, cool. First things first, could you send a screenshot of the code that moves the actor?

[lyric quiver]

K

[brazen pike]

You fixed the error?

[lyric quiver]

The actor is moved using the view of the player camera

[sour crater]

no.

says error is in there

[brazen pike]

where is this function, "get BP", where is that running and when

[sour crater]

well ill show you but i dont think i called the function yet

[crisp gulch]

It looks like you have a way of ignoring player movement already with the IsGrasped branch.

[sour crater]

okay

the white progress bar is the bar that has a bind to the percent

which is the Get BP function

[lyric quiver]

if that variable is true then it moves with the player camera otherwise it just acts like a normal cube

[sour crater]

ill get the ref that calls the protrait now

[crisp gulch]

Gotcha, so this is for freezing a cube actor, correct?

[brazen pike]

Okay, so right click on the "Resource Component" get node here, then click on "Convert to validated Get"

[lyric quiver]

yh

[brazen pike]

that way, it'll only run the code if it is valid

[sour crater]

dont we all just love sortting through unreal engine and their many event graphs

[brazen pike]

my brother in christ, you made the graphs

[sour crater]

XD not all of them lol

my dad did a lot of this

its family team

[brazen pike]

nice, that'd pretty be cool working with my dad, but he's more of a web design kinda guy

[brazen pike]

Why dont you attach?

[sour crater]

thats still cool in its own way

[ruby apex]

How to make such a thing?

[sour crater]

the delegate?

[ruby apex]

When I make a custom one it goes like this

[sour crater]

make a custom event right?

[ruby apex]

Thats builtin gui button onclick

[brazen pike]

This requires you to be constantly moving the actor to be right in front of the player. It'll be much easier to just attach the actor to the player and stop its movement (which will vary depending on how you're moving it)

[versed sun]

It will auto make the Event if you "Assign" instead of "Bind"

[ruby apex]

Thats DECLARE_DYNAMIC_DELEGATE_OneParam(FSomething, FString, Value);

[crisp gulch]

So something like this is what you want correct?

[brazen pike]

like this?

[ruby apex]

Yeah

How to make it

[versed sun]

Assign [your dispatcher here]

you can also make one this way

[brazen pike]

The object with the dispatcher needs to be a component. Then it'll be at the bottom of the details panel. If you dont have a component, but have a reference, then you need to bind to an event/function

[crisp gulch]

This is what I found worked for that. I created a branch at the begining of the tick with a new bool value I called IsFrozen.
When IsFrozen is true, it sets CustomTimeDilation to 0, which stops any timeline animation (if the object is using any), and then sets SetSimulatePhysics to false on the root object (in this case the cube) to pause any velocity, gravity, or other physics based force that's acting on the cube.

[ruby apex]

Sorry I still don't get it
I just need to subscribe to my custom DECLARE_DYNAMIC_DELEGATE Im passing as a custom parameter

@brazen pike

I just use .AddDynamic on the cpp side

And don't get how to do it in blueprint

[sour crater]

ill brb but im on the right track now thanks lemon and others

[ruby apex]

I mean how this

[brazen pike]

hmmm never done it with a cpp delegate, it doesn't work like a BP dispatcher?

[ruby apex]

Is different from this

[versed sun]

how to add the Value(String) ?

New Parameter in the Details Window

[ruby apex]

And they I've removed it and seems like it still works

[brazen pike]

this is the fastest way

[ruby apex]

Oh thanks I didnt see it

I've only seen 'create event'

[tribal blade]

Hey, is there anything in unreal for stuff like
"Press F to interact" where you can bind the 'F' to actually be an input action? there are ways to just get key names for input actions, but was wondering if there was something more convenient than me having to go through all my prompts and update them through code.

(maybe something w/ rich text block?)

[brazen pike]

like figure out what key the player has bound to a specific action?

[tribal blade]

yeah, just replace F with whatever the actual key for the inputaction is

[versed sun]

yes , its easy with #enhanced-input-system

[tribal blade]

yes, i am using that. is there any automatic way for unreal to do text replacement for me?

something like "Press <Interact> to interact" or whatever, and unreal knowing it means the input key

[brazen pike]

well I just did it manually

this is ue4 without enhanced input system

but I'm sure it's basically the same concept

[tribal blade]

yea i guess i can just do it manually, just making sure

[brazen pike]

I made this into a global function, so if you've made it once, call this on construction of any widgets and easy peasy

I imagine it's going to make localisation a nightmare, but I'll burn that bridge when I get to it

[tribal blade]

will it? F is F in all countries

[brazen pike]

the keyboard layout is not

[tribal blade]

oo yeah

[brazen pike]

it might not be a pain, im just expecting it to be

[trim matrix]

so I have this wierd thing happening where my actor for some reason can see itself

When I get the sweep Result it seems to be saying it's hit itself and not the actually physics actor thats gone inside of the box

[brazen pike]

if (OtherActor =! Self) { do_stuff();}

[trim matrix]

it still seems to see itself

[magic mica]

Question; how do I remove a static mesh from the PC? I have pick up the hat to equip it, and while wearing it, it will replenish X-amount of HP, and I want to destroy it when it runs out of HP pool, but can't find the correct nodes.

[ruby apex]

Is there a way to execute event in blueprint (call MyEvent.Broadcast();)?

[brazen pike]

If all you need is the hit actor and the hit component, then dont use the sweep result probably

[ruby apex]

Delegate*

[trim matrix]

okay so made it work but that sweep result is for some reason seeing itself for some strange reason

[brazen pike]

Is this the delegate that's exposed to blueprint?

[trim matrix]

so idea is I grab the component detected and check is simulating physics and if so do a impulse on the component

I would prefer to do it on the actor but I don't think there is anything I can call to get if actor is simulating physics

[trim matrix]

Have I done this right as I think I have but not sure

[brazen pike]

Okay, then just pass through the component, rather than the hit result

Unless you need the other info

[trim matrix]

to be fair this prob won't work cause again the hit result is bugged so it's saying hit normal is 0,0,0 which it won't be

[brazen pike]

Not off the red pin

[ruby apex]

I dont see any

[brazen pike]

You are in the blueprint that inherits the delegate?

[trim matrix]

i'm gonna have to do it manually aren't I

[ruby apex]

I'm looking for such a thing lol

[brazen pike]

it looks like this

[ruby apex]

Yeah but I don't need to subscribe on something

I need to call .broadcast() on my delegate

[frosty heron]

Broadcast is Call in blueprint

[frosty heron]

Delegate takes an event / function

[ruby apex]

Dont see calls here

[spark steppe]

i've never seen the red square pin as Output!?

[frosty heron]

You have to have Event Dispatcher

[frosty heron]

I have in some plugin, just some callback we can use

like HTTP request , etc

[brazen pike]

i know right, that threw me for a minute

[ruby apex]

So I want to have a callback back to my cpp code from the GUI widget

[spark steppe]

i think this expects EventSetup to be called with a valid struct

[brazen pike]

It's under "default"

[spark steppe]

this is most likely not supposed to be used there, someone correct me if i'm wrong

[frosty heron]

You prob have the most wisdom around the people online on this channel atm

[ruby apex]

Thats definitely not a thing Im looking for

[frosty heron]

Delegate is what you plugged to events

or function

Have you watch some videos about event dispatcher?

[spark steppe]

never undererstimate the lurkers 😄

https://tenor.com/view/group-text-lurker-lurking-gif-5922929

[ruby apex]

I did, didnt help

[brazen pike]

im hoping if I lurk in the cpp channel for long enough eventually I'll understand cpp

[spark steppe]

nope, understanding cpp involves more pain

[ruby apex]

I basically need to do this thing in blueprint
Why is it so difficult?

[frosty heron]

In blueprint you just use Call

[ruby apex]

OnClosed is the delegate

[frosty heron]

You need to make an event dispatcher in blueprint

the same way u declare delegate in CPP

[brazen pike]

I dont think you can call using the delegate ref in blueprint. You need a ref to the delegate's class and call it from there

[spark steppe]

again... it's not supposed to be called from within the setup event

or rather from the parameters struct blob

[ruby apex]

Yeah Im using it later, moved just for the sake of simplicity

[spark steppe]

if this is your own cpp class, make a method which takes the parameters and calls the dispatcher

[frosty heron]

Yeah kinda weird to have it in a struct that you break... does that even work?

[ruby apex]

Thats what Im trying to avoid

[ruby apex]

Whats the problem?

That works in cpp

[spark steppe]

even epic uses that in some places iirc

[ruby apex]

Just moving some GUI logic into blueprint

[frosty heron]

I don't know, I do delegates in CPP but not like that

my cpp not good enough to understand how other ppl does stuff

[ruby apex]

How do you do it?

[ruby apex]

So I have the same thing

[frosty heron]

you probably have more help in #cpp tbh

they have big brain people there

[shell flower]

how exactly does one put this 'AICon' on a character/pawn?

[sour crater]

is lemon still here?

so i have where we set up the hud, can i pull you aside for some mentoring?

if possible?

[surreal peak]

AICon just means AAIController. which is a child class of AController, and a sibling of APlayerController. AAIController usually is used by AIs if they control a Pawn/Character.
You can either manually spawn one, and use it to possess a Pawn/Character, or you can check the DefaultSettings of your Pawn/Character. There is a drop-down somewhere that controls in which situations an AIController is automatically spawned.
Usually the options are "not at all", "when spawned (vis SpawnActor)", "when placed into the level", or "both".

[brazen pike]

probs dont pull me aside. There's many people here who are significantly more knowledgeable than myself. Ask questions here and if I can't help someone else might be able to

[sour crater]

okay alright but im gonna feel dumb

lol

in that it is a 7 step to set up the hud. I just need to add a ref to the resource component there?

[brazen pike]

As an example of someone more knowledgeable, I spend a good chunk of my time (when making multiplayer features) looking at a pdf written by Cedric, the guy who just answered a question

[brazen pike]

What do you mean

[sour crater]

Yeah but when you got someone like me, who can barely understand the doc unless i code with it, i feel dumb a lot lol

WEll going back tp the other question at hand

remember how the resoure component wouldnt access or read? Well, you told me to make sure the resource component was vaild

i guess i still have to find the right ref

because it should be calling it already

urgh

brain steams out through my ears

[frosty heron]

How can it be invalid? Unless you destroy the comp or the actor

[sour crater]

no i still have both

the comp is within the bp player character

[brazen pike]

what is the error you are getting

[frosty heron]

So what's the error again?

[sour crater]

ill post relative code and error right noiw

one second

resource comp (what i added that led to the error)

Get BP Function which is bind to the percent within the widget

[frosty heron]

Multiplayer 🫠

[sour crater]

lol?

[lunar sleet]

The engine does it for you

[frosty heron]

You are using Get Player Character 0 in Multiplayer?

[sour crater]

yeah?

[frosty heron]

I suggest to read Cedric compedium first

Or wizard articles

[brazen pike]

oHHH this is multiplayer?

[frosty heron]

it's all pinned in #multiplayer

[sour crater]

lol yeah sadly

[frosty heron]

You basically should never use Get Player character 0

In multiplayer context

[sour crater]

I see

[frosty heron]

It will give you different result, depending whos calling it

[lunar sleet]

Use Get controller and cast to the right thing

[brazen pike]

not always true, but generally

This is in a widget however, so get player character will work perfectly

[frosty heron]

Ohh ok

Yea I would just get the owner of the widget if that's the case

[brazen pike]

I would say turn the get node into a validated get (for the resource component), since this will run every frame it should work

it'll wait until the component is valid before displaying something

[sour crater]

how long does it take for it all to click? I know the basics but not everything thats basic

XD if that makes sense

[frosty heron]

The jump from single player and multiplayer is quiet a leap imo

[sour crater]

yeah lol it is

[frosty heron]

depends on how complex the game is tho

[sour crater]

(complex lol)

[frosty heron]

if u want to do Turn based stuff, knowing replication and RPC is probably enough

[brazen pike]

I tried learning it on my own, and wasn't able to get it until I was hired at a studio and was sat down and told how it all works

[frosty heron]

You are living my dream

I lived in Australia too, there are barely any game studio 😭

especially in Perth

[sour crater]

sorry for the dumb question. What get node do i convert?

[brazen pike]

yeah I'm located in perth 😭

[frosty heron]

For reallll 😄

[sour crater]

In USA there is only one or two states that has game studios

[brazen pike]

the get node for "resource component" coming out of the player character output pin

I work remote for a tiny studio in new zealand

[sour crater]

thank you

no errors

[brazen pike]

so woooo living the dream of having nobody in my field I can talk to IRL and because I work from home seeing nobody all day for 5 days of the week wooo 🎉 living the dream

[sour crater]

now i just have to get the BP to increase loololol

trust me man

its worth it

you could be holding up a sign

instead you code on your butt lol

[frosty heron]

No errors don't mean everything is fine tho

[sour crater]

oh no

[frosty heron]

you shouldn't be accessing something you hvaen't set

[sour crater]

the bp in my code is not increasing

look cold summer

can you help me with this one then let me get a screenie

[frosty heron]

No ser, I got a deadline my own

[sour crater]

XD

all good

but yeah i understand

i have it access through comma key

[frosty heron]

I would get the owner of the widget -> Get the character -> Get the component , then just display w/e I need to

[sour crater]

what i have right now if you press comma, it wastes mana

i want it to increase bp

[brazen pike]

the variable isn't increasing, or the widget is not increasing

[sour crater]

the var

the mana drains however

[brazen pike]

where are you changing the BP

Oh i see.

[sour crater]

i just noticed the equipment comp

(hate learning my dads code)

i have a lot to look through

let me get back to you

sorry for being a bother

but thank you for the advice to look for the mana

[brazen pike]

Btw, the mana isn't going to replicate properly

[sour crater]

it does though

works perfectly

connected to the combat system

[brazen pike]

You're setting it on the client, but not the server, since it's a replicated variable it will be updated only on the client and not the server. Therefore, if it is ever changed on the server, the client's variable will then update to be the same, but it doesn't work the other way around

Any input presses will be on the client

[sour crater]

i see

[brazen pike]

Unless you manually do an RPC to the server and change it afterwards. I can imagine that being a form of client prediction

[sour crater]

thank you for that

glad i came here

[magic mica]

Hey ya'll, how do I remove a static mesh from the player that was equipped in game?

[frosty heron]

Get a reference to the static mesh then destroy the component or set the static mesh to none

[trim matrix]

how can i stop an animontage? i have this montage that i start when i reload but this doesn't stop it

[frosty heron]

that should stop it, assuming you have an active montage

[sour crater]

i have another dumb question for yall

The call update character, how can i add the var BP and Max BP to it

[trim matrix]

yes, i see the animation play when i reload but it doen't stop when call the stop animontage

[frosty heron]

Make sure the stop anim montage is called

[trim matrix]

i have this to switch weapons, and it still switches weapons but while doing the animontage

[brazen pike]

find the dispatcher in your BP, then click "add input" in details

[sour crater]

what is a delegate

i need to find the dispatcher yeah

[brazen pike]

it'll be below variables

[sour crater]

i dont have a dispatcher

just a setupdispatcher with nothing on it

[brazen pike]

So where is this

[sour crater]

equipment comp

[frosty heron]

@trim matrix Works for me

[brazen pike]

if it is called from there, it will be there under the "event dispatcher" section

[sour crater]

hold on

under this one we got stuff

thanks lemon ill take a look

found it

thank you lemon your awesome

i even looked at the documention for dispatchers before asking, but how come i cant change the vars and the dispatcher is a read only and greyed out

[trim matrix]

is it maybe because i am using a montage?

this doesn't work btw

[frosty heron]

I am using a montage

works btw

You are playing a montage off a skeletal mesh component

Meanwhile thr target is character

Do this instead : Get First Person Arms -> Get Anim Instance -> Stop active montage or something like that

Stop anim Montage probably target the default Mesh Component

@trim matrix

[trim matrix]

thanks man, finally it works

thank you

[frosty heron]

I will guess that Stop Anim montage just stop montage on this specific Mesh component inherited by Character class

[lime basin]

any advice how to offset hand/bow position when this animation is playing when on idle it all looks okay

[lunar sleet]

which part of this is #blueprint related 😄 ?

there's an #animation channel if you need

[sour crater]

got it

[lime basin]

all of this is done in blueprint

[lunar sleet]

bruh

lol

[lime basin]

thats the best I got idk 😛

[random pulsar]

Hey guys i am having an issue that i cant solve when i open inventory its fine but when i press one more time it removes all widgets so i am wondering how can i fix it to remove only inventory widget here is the functionality that opens and closes it

[lunar sleet]

remove from parent

you'll need a ref to said widget ig you already have a ref

[frosty heron]

How to fix from removing all your widget? Don't call remove all widget to begin with

[lunar sleet]

also just a tip, you don't need to spaghettify the code, you can Get that Widget ref multiple times np

[sour crater]

at the point where im looking for all the ways the widget is not connected to the BP stat lololol

hate that part of coding

no errors?

okay!

still dont work

sulk

[dapper grotto]

I'm trying to change cloud material parameter of volumetric cloud component (using simple clouds material from plugin) from blueprint, but it seems to work different than how it works for meshes. I didn't find anything about this being a problem for anyone else though for some reason. So I must be doing something wrong, but I can't figure it out. I only found here on the Discord where someone asked how to do it in C++ that you have to set the material again to the dynamic instance, but that still didn't do anything for me. Now I am clueless.

[glass blade]

is there any short cut to select group of nodes connect their execution pin all together instead of one by one?

[dapper grotto]

no, afaik

[glass blade]

BP is slower to "code". Have to learn to blind type with one hand

[dapper grotto]

but I don't know much 😄
I find it strange though that there are no helpers at all with wiring blueprints. It's so annoying. But it would help soo many people. Even just simple stuff like when you select two nodes, it could suggest what pins to connect and you hit space - bam. So easy. Maybe there is a plugin for this?

[frosty heron]

if there's any advantage to bp is that, it's faster to prototype than writing actual code

[glass blade]

Ik

It's frustrating when you pull the node and try to connect it but miss the exection pin to connect a bit then you have to pull it again

[glass blade]

I don't know if there's a plugin. I'm searching myself too

[frosty heron]

doesn't happend much to me. Are you having low fps? or maybe you are cooking spaghetti?

try to use re-route nodes when you can

[glass blade]

cooking spaghetti?

are you cooking one?

[frosty heron]

https://pbs.twimg.com/media/ELn1KEoXsAoNHcj?format=jpg&name=large

[glass blade]

I'm not a total beginner. But everyone cooks spaghetti when starting out.

[frosty heron]

Im not saying you are but I keep my nodes close to each other, I don't really miss when connecting nodes

[glass blade]

I'm working so fast and my pc is old that it freezes some times. That's when I miss to wire nodes

I'm in UE5.3.2

[random pulsar]

😁

[elfin hazel]

I think the point is that BP prototyping could be faster, even something simple as, if you drop a node close to another node, auto connect the execs. There's definitely potential that's not being used.

[frosty heron]

You can just grab Grid again for nodes that are too far

[glass blade]

Maybe they bring Verse to UE5?

[random pulsar]

Btw how can i make a shop,for my dude to sell and buy things?))

[glass blade]

I'd much rather prefer something similar what Unity is doing with it's scripting with C#

but with Verse
