How do you obtain the "Get" node ?

[dark drum]

Right click on a variable and convert to a validated get.

Also, need to clear the current actor after removing highlight. Forget it in the initial screenshot.

[dark drum]

Are you able to follow the logic behind what's happening or would you like an explanation?

[tight moon]

What kinda of variable is the Current actor ?

Otherwise I think I get it.

@dark drum

[dark drum]

Just type actor.

[tight moon]

It doesn't work.

[dark drum]

Show how you've set it up.

[tight moon]

Still not working.

[dark drum]

There's a few issues.

[tight moon]

FINALLY

Just have to order everything now.

[frosty heron]

@tight moon you should thank pattym for doing your homework

[copper chasm]

I’m going to do my last new project for this character creator nonsense, and I’m going to sketch it all out in psuedocode first so hopefully I don’t run into another wall 10+ hours in

[dark drum]

I wish I have access to UE5 when i was at uni. It proper bumbed me out when it dropped a few weeks after I graduated. It felt like learning kismet was a waste of time haha.

[frosty heron]

I wish I self study instead going to uni 😭

well, game's club and pizza was fun times but other than that. Writing essays sucks

[dark drum]

Get to uni for 12, stay in the labs til about 7-8 and then went to the pub lol.

[drowsy steppe]

Hey guys, I need some help. I don't know why this interface for gameplay tag does not work anymore, it can't see the tags on my other actor, even if they have it. it always return false. I set it up with C++ and yesterday it was working fine, now it's like tags do not exists anymore

[dark drum]

I've been working on this the last few days. It's turning out pretty well, just need to sort out some checks for allowing different stand to sit anims depending on the direction.

[tight moon]

Looks like this now but thank God everything works as intended.

So yeah @dark drum thanks a lot for the help, frankly there's no way I would have done something like this myself.

[dark drum]

Show how you implented the get ower tags function in the interface.

[drowsy steppe]

first is the .h file and second the .cpp file

it shows up like this

yesterday it was working, i tested it and it returned correctly the tags

[dark drum]

Where do you define 'OwnedTags'?

[drowsy steppe]

I don't know i just added the code ChatGpt gave me since i couldn't find any tutorial online. By the way i just took out the gameplay tags from "get owned tags" and now it's working

[drowsy steppe]

before i was taking my tags from a new variable of tag container i created in blueprint but it wasn't working. i don't know why yesterday it worked and now it wasn't but doing so (taking the tags from "owned tags" it's working

[dawn gazelle]

"MyManager" doesn't do a good job describing what the actor is, and then in your screenshots it appears that you're checking the tags of "Tools". Are your "Tools" children of "MyManager"?

[drowsy steppe]

No, I made a class for a tool, one for a manager and one for the pawn doing the same as the picture with c++. also i added themodule "gameplaytags" on the build.cs file.
Then with blueprint i'm working with events, casting, and the gameplay tags interface to communicate between them to have my pawn make their routine receiving the command from a single manager

[dawn gazelle]

Ok, what does your implementation of the IGameplayTagAssetInterface look like for your tools?

[warm parcel]

Hello. I have two objects connected by a spline mesh component. The spline mesh component belongs to the wheeled cart.

I have it updating as the cart or the spray wand moves, but unfortunately, when I move the cart there is some “lag” between the component’s location updating and the spline endpoint updating. You can see this as the hose appears to disconnect from the wand as the cart moves. The spline endpoint update is happening on tick.

Is there a way I can make it happen at the same time that the cart’s movement is updated? The cart’s movement is driven by physics.

Thank you!

[drowsy steppe]

Sorry if i don't answer correctly. I'm a noob and i'm not native english speaker. I appreciate your help by the way. The IGameplayTagAssetInterface is the same between manager, tool, and pawn. I wrote it the exact same way apart from the AMyPawn name. The tools get spawned by the manager and added in an array. In the blueprint of the tool i have an event which gets triggered by the manager that add or remove a tag for the tool. Based on the tags (occupied or not), the tools get chosen and assigned to a pawn that goes to the tool. When the pawn finishes the job it returnes a message to the manager who removes the Tag from the specific tool. Now it's working, thank you very much. I wish there was an actual documentation for this, or if there is that i was able to find it

[mild jacinth]

if I have event dispatcher whats the easiest way to see where the function is implemented.

i can only see 'call x function' but idk what is listening

[dark drum]

I don't believe there's anyway to see what's bound to an event dispatcher. It would be useful though.

[mild jacinth]

thats weird. ..

[ember veldt]

You could just create an array of actors that something adds itself to when it assigns to the event dispatcher

[lunar sleet]

And if editor time only just find ref and delete the “bind” part

[summer bolt]

adding on to that when i give phyusics to the skeletal mesh it collapses

how can i give it a capsule in the meshs shape

[mental trellis]

A capsule isn't teh shape of your mesh.

Unless your mesh is a capsule.

[summer bolt]

how can i make one that shape

[mental trellis]

Change your mesh so it's a capsule.

Kinda makes having a skeleton a bit pointless, though.

[summer bolt]

i want to use the skeletons for animations

wait

would implementing an idel animation fix that

idle****

[surreal peak]

Fix what?

[summer bolt]

the skeleton just collapsing

when in a pawn with no capsule

[surreal peak]

The capsule on a character is not the same as the meshcomponent

[summer bolt]

I know

[surreal peak]

If you simulate physics on a skeletal mesh component and the skeletal mesh collapsed strangely then you need to modify the PhysicsAsset of the Skeletal Mesh

[summer bolt]

Ty

thats what i needed

[maiden wadi]

I'm curious why you need to know? What is the use case for it?

[mild jacinth]

debugging purposes as i didnt develop code so i would need to know where it is being binded but luckily i found it already

[maiden wadi]

Ah, you should generally be able to open the class it's from or search it by name in the find in blueprints to see any cases of a Call/Broadcast/Bind

[dark drum]

I think he was referring more at runtime. I've had a few cases where I wanted to see what had be bound to an event dispatcher at a given time but i wasn't able to find anyway to see it. There could be a way as the debug tools can be pretty extensive haha.

[copper chasm]

I always put a little text comment on my calls and bindings

this is going to sound stupid - if I make a custom event that does all the ED bindings I'll need in a given blueprint, I can just call that event on beginplay and the bindings should be set, right?

like idk why it WOULDN'T work, I've just always strung them off my beginplay and I realize that can get ugly

[lunar sleet]

Looks more like it’s not their code and don’t know how to use the search function 😀

[faint pasture]

tick group

endpoint is being moved before physics is ran

change tick group to post physics

[warm parcel]

Thank you!

[haughty jolt]

how can i make the icon onyl spawn on the right team or only make it visible for the right team? can someone help me

on the pictures you see the whole project

[tight pollen]

hi, DataTable can be translated?

[dawn gazelle]

From what I know, FText fields within the DataTable can be translated fairly easily.

[surreal bridge]

I am using a weight system to determine certain outcomes.

However, when I go to generate a random float, it returns the same number multiple times.

I tried a few things, like adding a seed to it that uses the millisecond

And I changed them from pure nodes into impure nodes but the result was the same.

It is in a function library so I can't add a delay

[crude dew]

Any ideas why a spawned enemy would just stand there and not move ? I am using the Simple AI Move To Node to move to a target location but some do it but occasionally one will spawn and not move and walk on the spot please? I do have the Auto Possess AI set to Spawned or Placed in World also.

[faint pasture]

show code

[crude dew]

https://blueprintue.com/blueprint/c3um21y4/ This is the blueprint for the enemy, I checked that X has a target location set which is valid too I put it on BlueprintUE as a picture would have been too big hope thats ok.

[surreal bridge]

This is one of the places it is calling the random but it returns the same thing like 5 or 6 times then changes to a new random and does the same.

I have it calling the function 100 times just to debug and see all the outputs

[dawn gazelle]

You'll need to show some more of what you're doing.
I'm doing this for example, and I always get varying numbers output, so it's not likely something to do with the random number generation itself.

[surreal bridge]

This is one of the functions

And this is the one that is calling it:

Actually. I just added a log to the end after the random number is made and it does look like it outputs different numbers, but its odd that it picks the same cards.

Let me get the log really fast

Looking at this, I am thinking that something might be off with something other than the random.

The numbers don't add up to what i was expecting them to be. So it could just be getting the last card or something like that:

Yeah.. I found my issue. For some reason, the total weight is starting off (at least in this test) at 2206. Which is way more than the total weight should be.

[hidden cape]

kind of a noob question...when would you use a macro over a function

[surreal bridge]

Well, a macro can have many exec pins but a function can't have more than the in and out.

[hidden cape]

hmmm ok thanks

[surreal bridge]

A macro that I made is to only execute if it reaches a certain time, otherwise it will output a different exec line

[hidden cape]

can i have a set timer by event in a macro?

ah neat

[surreal bridge]

Yep

[hidden cape]

the event would then go to the input, add an exec pin, and have the custom event outside of the macro?

[surreal bridge]

That sounds about right

[hidden cape]

sweet

ok thank you

[surreal bridge]

No problem

[mild ibex]

I'm trying to make a function / macro to replace a timeline because I have a dynamic number of static meshes that have different start and end points and all I really need is an alpha on a timer. I dont want this running on tick, I'd rather use set by timer but it's not really working

[fickle rampart]

Timers are limited in their usage in terms of not having a body to run within the specified time to run like timlines do. Timers are a good and lightweight way to trigger an event after a certain time has passed. Like a stop watch. Timelines instead can run and execute logic within that timespan.

So I am not entirely sure what you try to achieve but timelines or Tick-Events might be more what you want.

[fickle rampart]

In addition:
Timelines can only be used in Actor-BPs as far as I know, which is frustrating in my opinion.

To achieve a similar, custom functionality, you could try and create a custom BP-Component which's only task is to run logic within the tick event and stop after a timer ended. So a timer and Tick-Event combination within a component. And this component could be used multiple times for different use cases.

Edit: But BP-Components can also only be put into an actor I think. Which is why timelines are still a better solution as long as there is no real reason to outsource such functionallities into a custom component .

[worthy fractal]

Is there a good tutorial on how to make a RPG character creator like in Caves of QUD/ Fallout 1 and 2 and other CRPGS ?

whenever I look for character creator tutorials they are all about visual customization, which is nto what I am looking for.

[mild ibex]

Ohh I see. Because yea, think of it like multiple moving static meshes. I got close with a function but the set timer keeps redoing the function so my local time keeps staying at 0.02

[fickle rampart]

Wait... now you mention "redoing":
You can set timers to "loop" a function/event. But I never tried this an have therefore no detailed knowledge to help you with this variant.

In theorie, setting the timer as small as possible and enabling looping could do what you wrote/want.

But I do not understand what you mean with "staying at 0.02". What exactly is your problem?

[mild ibex]

So, it does work how I would expect outside a function. It does exactly what I'd want. But once it's in a function there is a local variable that adds up the loop value and should match a duration.

But it gets to 0.2 or something and goes back to 0 so the timer constantly goes instead of reaching a condition to clear the timer

[fickle rampart]

Don't use local variables if you want global ones instead. Using local variables in a function resets the variable as soon as the function reapeatedly triggers again.

[mild ibex]

Ah, I thought I had tried a global variable. I'll try that again but it didn't seem to work as I recall

[fickle rampart]

If that doesnt work then there might be some other logical error. Hard to tell to be honest without screenshots.

[rotund barn]

how can i get a wheel axis input? i cant seem to get any output value no matter what i do

[zealous moth]

@rotund barn in the input mapping, set it as an axis 2d and it should output the middle mouse as a float of -1 or 1

[rotund barn]

ohhhh yeah, sorry, i completely forgot to change that. i spent an hour on this today, another hour yesterday. i feel dumb : D

[sweet silo]

hi !
So i have a capsule staying inside some sort of enclosure.
The capsule is started by a ' set timer by event" every 10 sec.
Then i wanna know if the capsule stayed at this position for the next 10 sec or if it collided with some sphere i set up.
How can i create the second timer ? thanks 🙂

for now i have this but not working

[lyric basin]

In my head, I am thinking that you could use an AND BOOLEAN for this but I'm on mobile so I can't check for sure. But you would basically have a delay start for however much time that fires into a Boolean setting it to false at the end. This first bit is the 10 second timer and is used to check if the clock is running.

You could then use the begin and end overlap nodes for the capsule to monitor whether it is inside. Have the end overlap fire into another Boolean setting to true if end overlap fires. This will tell you if the capsule left the space.

Both of these would then feed into an AND Boolean and if BOTH are false, then that means that the ten seconds timer elapsed with the object still inside

Make sense?

[summer bolt]

I realise now simulate physics is meant to make the sketal mesh collapse

Is there a way i can use the collision of that skeletal mesh without stimulating physics on it

[lyric basin]

What value are you trying to change specifically?

[lunar sleet]

You might be missing some flags like EditAnywhere or such. Show #cpp your setup

[maiden wadi]

Generally you're supposed to use GE's to affect attributes.

[frosty heron]

@mild ibex if performance is the concern, timeline is also running on tick.

And if you are trying to do something frequently and use a timer with 0.01 as the value, you will end up with more overhead.

If something is of fixed length, use timer. Otherwise tick.

You can just make a component that runs something on tick and stop it self after the time reach its limit

Time is just time plus delta time

[mild ibex]

No it's not performance thankfully. I just want a way to do a timeline esque process without having to dupe a whole bunch of time lines. Basically moving a lot of items around a circle that all have different starts and ends. And they aren't spawned, already exist in the world but there could be any number of them, so it's a bit tricky.

[obtuse oriole]

is there any node for changing rendering settings or I have to use the execute console command?

[thin panther]

game user settings and it's functions are mostly for those

[surreal peak]

Do you just want to be able to trace against it or do you want it to semi physically react to obstacles, as if sim physics and the animations are blending?

[crude dew]

Anyone know why a spawned character with a simple move to node would not move but randomly mobs before and after it spawned work fine please?, Seems to be random whether it works or not.

this is the code for the walking part prior to this on Begin Play I have a Delay node of 0.2s (Thought maybe was a possession issue)

I checked Target Location and the value is set to the location it should walk to, I have a NavMeshBounds volume which is useable, So Im out of ideas why it isnt working. 😦, Have noticed another weird thing its spawning the enemy (Walking on the spot) but it also loses all its Collision Propertys, The other ones which are walking and moving fine the collision system works.

[surreal peak]

Are you sure the Character does in fact have a valid AI controller?

[crude dew]

I tried using OnPossessed event to check it has a valid controller.

Its using the default AIController

AutoPossess is set to Placed in World or Spawned.

and this is run in the level map ( I have multiple spawner actors) and the Spawn the actual enemy code inside the spawner

[surreal peak]

One thing I'm partially sure of is that you don't want to use Destinatin and TargetActor

Cause TargetActor should in theory cause the AI to follow, while Destination won't.

[crude dew]

I can disconnect the Destrination (Only added it to test it) 🙂

[surreal peak]

The TargetActor is also valid?

[crude dew]

I,ll promote to variable and make it visible in editor to check

[surreal peak]

What does the MovementResult print on the OnFailed pin?

[crude dew]

Cast Failure

[surreal peak]

You could just plug an isvalid with a print

[crude dew]

Ok added this

the first 2 spawned fine then the 3rd just walks on the spot and collisions dont work

So spawned 7 enemys, 1 - ok, 2 - ok , 3 - bugged , 4 -ok , 5 - ok :S 6- ok 7- ok

[surreal peak]

It's probably important to figure out why the 3rd one bugs inside the AIMoveTo node.
I assume you have no C++ knowledge?

[crude dew]

I have a bit of c++ knowledge but no expert in it.

[surreal peak]

The MovementResult could be the first thing to check

[crude dew]

rerun 1st - bugged and 2nd spawned was ok lol

[surreal peak]

Yeah it's probably cause the AI can't find a path

And you have no fallback

You can try, just for debugging, to add a delay and rerun the IA MoveTo if it fails

[crude dew]

Ok added a 1 second delay if failed and restart the AI Move to process

now 1st - Bad, 2nd - Bad, 3rd spawned ok , 4th bad xD

[surreal peak]

And they don't recover?

[crude dew]

Nope

[surreal peak]

Can you display the navmesh while playing?

[crude dew]

You can see a lot of them here have spawned and walked to location but some just spawn and dont move and disable collisions

how can i show nav mesh during play ? I know it,s P in editor.

[surreal peak]

probably via console

show navigation

The "Disable Collision" part seems strange. I don't think that's a normal behavior.
Do you disable collision in any of your code?

[crude dew]

Nope theres nothing to disable collision

[surreal peak]

Actually

Lemme check something real quick

[crude dew]

Odd i eject from controller and press P and have Show Navigation enabled but it doesnt display the navmesh

but here is navmesh before run

[surreal peak]

So what exactly does the Enum print when Fail calls?

Or does Fail not call?

[crude dew]

Fail does not call.

[surreal peak]

Does Success call?

[crude dew]

Nope.

[surreal peak]

Not even for the ones that work normally?

[crude dew]

for the ones working normally it does

[surreal peak]

And for the failing ones neither pin calls?

eh

[crude dew]

yup

[surreal peak]

Are there other AIMoveTo Nodes?

[crude dew]

nope

The ones not walking do get to the patrol point collection node

I think its something to do with the replcated EState maybe ?

[surreal peak]

I'ma bit confused what that AIMoveTo node even is in code

They have like 2-3 versions of it

It must be the UK2Node_AIMoveTo cause the other one has way more properties.

Strange to make a custom node for this..

[crude dew]

maybe i,ll try the Simple Move To Actor

[surreal peak]

"Simple order for Pawn with AIController to move to a specific location"

Does this show whne you hover teh AIMoveTo node?

[crude dew]

Yes

[surreal peak]

Okay

[crude dew]

can see why im a little confused why some are spawning "ok" and others are not.

[surreal peak]

The node can generally fail before it even reaches the point of handling the pins

Mostly if there is no valid AI Controller

[crude dew]

Ok if i add a delay after Begin play would this give time to "possess"

but no AIController would not disable the collisions on the mesh's ?

[surreal peak]

In theory you shouldn't run this on BeginPlay, but rather on Posessed

But I thought you tried that already

[crude dew]

i did try the delay and OnPossessed event.

[surreal peak]

And the delay doesn't make it work either?

[crude dew]

nope

[surreal peak]

Does your project have C++?

[crude dew]

no its all blueprint im afraid.

[surreal peak]

Does the code even reach the AIMoveTo node for everyone?

[crude dew]

It must do for some of them who spawn because they walk to locations but for some others they dont even enter the "cycle"

[surreal peak]

The thing is, this is the code that is used for the node:

UAIAsyncTaskBlueprintProxy* UAIBlueprintHelperLibrary::CreateMoveToProxyObject(UObject* WorldContextObject, APawn* Pawn, FVector Destination, AActor* TargetActor, float AcceptanceRadius, bool bStopOnOverlap)
{
    if (WorldContextObject == nullptr)
    {
        if (Pawn != nullptr)
        {
            WorldContextObject = Pawn;
        }
        else
        {
            UE_LOG(LogAIBlueprint, Warning, TEXT("Empty (None) world context as well as Pawn passed in while trying to create a MoveTo proxy"));
            return nullptr;
        }
    }

    if (Pawn == nullptr)
    {
        // maybe we can extract the pawn from the world context
        AAIController* AsController = Cast<AAIController>(WorldContextObject);
        if (AsController)
        {
            Pawn = AsController->GetPawn();
        }
    }

    if (!Pawn)
    {
        return NULL;
    }

    UAIAsyncTaskBlueprintProxy* MyObj = NULL;
    AAIController* AIController = Cast<AAIController>(Pawn->GetController());
    if (AIController)
    {
        UWorld* World = GEngine->GetWorldFromContextObjectChecked(WorldContextObject);
        MyObj = NewObject<UAIAsyncTaskBlueprintProxy>(World);

        FAIMoveRequest MoveReq;
        MoveReq.SetUsePathfinding(true);
        MoveReq.SetAcceptanceRadius(AcceptanceRadius);
        MoveReq.SetReachTestIncludesAgentRadius(bStopOnOverlap);
        if (TargetActor)
        {
            MoveReq.SetGoalActor(TargetActor);
        }
        else
        {
            MoveReq.SetGoalLocation(Destination);
        }
        MoveReq.SetNavigationFilter(AIController->GetDefaultNavigationFilterClass());
        
        FPathFollowingRequestResult ResultData = AIController->MoveTo(MoveReq);
        switch (ResultData.Code)
        {
        case EPathFollowingRequestResult::RequestSuccessful:
            MyObj->AIController = AIController;
            MyObj->AIController->ReceiveMoveCompleted.AddDynamic(MyObj, &UAIAsyncTaskBlueprintProxy::OnMoveCompleted);
            MyObj->MoveRequestId = ResultData.MoveId;
            break;

        case EPathFollowingRequestResult::AlreadyAtGoal:
            World->GetTimerManager().SetTimer(MyObj->TimerHandle_OnInstantFinish, MyObj, &UAIAsyncTaskBlueprintProxy::OnAtGoal, 0.1f, false);
            break;

        case EPathFollowingRequestResult::Failed:
        default:
            World->GetTimerManager().SetTimer(MyObj->TimerHandle_OnInstantFinish, MyObj, &UAIAsyncTaskBlueprintProxy::OnNoPath, 0.1f, false);
            break;
        }
    }
    return MyObj;
}

The top part is it just trying to grab a Pawn and AIController

In one way or another

[crude dew]

Ahh i,ll check the UELog output as well i forget to check that.

[surreal peak]

The main issue is that if it returns early due to !Pawn or due to AIController not being valid, I don't see it handling that case on the node.

[crude dew]

LogBlueprintUserMessages: [BP_Enemy_C_0] Server: Blocked
LogBlueprintUserMessages: [BP_Enemy_C_2] Server: Blocked
LogBlueprintUserMessages: [BP_Enemy_C_5] Server: Blocked

Ok seems the failed ones are being Blocked but not sure what this means.

[surreal peak]

Yeah that makes a bit more sense

That's the MovementResult enum

[crude dew]

So are they saying "Hey i cant reach the location?"

[surreal peak]

UENUM(BlueprintType)
namespace EPathFollowingResult
{
    enum Type : int
    {
        /** Reached destination */
        Success,

        /** Movement was blocked */
        Blocked,

        /** Agent is not on path */
        OffPath,

        /** Aborted and stopped (failure) */
        Aborted,

        /** DEPRECATED, use Aborted result instead */
        Skipped_DEPRECATED UMETA(Hidden),

        /** Request was invalid */
        Invalid,
    };
}

[crude dew]

Ok i guess the question is now "Whats blockling them"

[lunar sleet]

#gameplay-ai is a better channel for this stuff usually but anyways use Visual Logger to find out exactly what the issue is

[surreal peak]

Try adding this to your console log LogPathFollowing Verbose

[crude dew]

Ah sorry for the incorrect thread.

I thought it was a blueprint issue 😦

[surreal peak]

No worries. #blueprint is a melting pot anyway

[crude dew]

lol

[lunar sleet]

VisualLogger should be able to give you plenty of verbosity (if you need it)

[crude dew]

I set them to Enemy Object and set Collisions to only Overlap so Enemys should not Block other Enemys from moving

[lunar sleet]

Under Tools->Debug btw

[crude dew]

thank you

[surreal peak]

This is not a Collision block

It's most likely that your AIs affect Navigation and alter the NavMesh.

Can you check if the Capsule has CanEverAffectNavigation turned on?

[crude dew]

No not checked.

[surreal peak]

The randomness then comes from the AI sometimes spawned and requesting when the other one is on top of the spot I guess?

[crude dew]

I mean unticked.

[lunar sleet]

You should see holes in the mesh if that was the issue

[surreal peak]

Yeah I tried to have them show the NavMesh during play

[lunar sleet]

Well maybe not if it’s not dynamic ig

[surreal peak]

should be show navigation fwiw

[lunar sleet]

You can usually just press P assuming it’s PIE

[surreal peak]

Not if you are actively playing

You'd need to eject I guess

[lunar sleet]

I can’t rmbr but yeah maybe

[crude dew]

Ye i tried P when ejected but it doesnt show it. .

[crude dew]

Nope some can spawn after the "blocked" one has spawned and walk fine.

Ignore Collisions is set to enabled when spawning them, at least I have a error to google now rather than random, So thats very helpful 🙂 ty

[lunar sleet]

If your navmesh isn’t showing at runtime you might be moving the landscape from 0,0,0 somehow or your nav volume is glitched

You can try deleting the navmesh volume and readding it

[crude dew]

location before play

if i eject and select the NavMeshBounds in the world outliner and press F it sends me to this location

[surreal peak]

There should be 2 nav mesh related actors in your outliner

One of them should have checkboxes to debug draw

[crude dew]

NavmeshBounds Volume has no option to Debug Draw and RecastNavMesh has no option too.

I know this code is bad but just testing something.

ok every 3 seconds spawn enemy

[surreal peak]

I'm pretty sure one of them should definitely have debug options. Cause that's what you toggle with p iirc

[crude dew]

Ok new move to code made it as simple as i could

so they should spawn and pick to move to 1 of 4 possible locations

[lunar sleet]

Increase your acceptance radius a little

Like 50

But if they’re not moving it’s likely that navmesh that’s not showing

[crude dew]

but wouldnt ALL of them not move not just some of them ?

does not print anything so its not failing and theres no "Blocked" message in the output log either this is so odd.

The X does not move but knows about the actor locations. :S.

im all out of ideas gonna have to go watch some videos on this because a code this simple shouldnt be randomly failing surely... Not intermittently at least.

[lunar sleet]

All these guys are spawned or some placed ?

[crude dew]

All are spawned

[lunar sleet]

Ok. Did you use visual logger yet ?

[crude dew]

i just brought it up not sure what im looking at though 1st time i seen it

[lunar sleet]

Ok, start logging, then play the game, do what you’re been doing

[lunar sleet]

Click on each of those frames one by one to see which one says Blocked

Spawn less dudes if need be

[crude dew]

ok i added 15s delay between spawns should give time to pause and check log

[lunar sleet]

Hopefully you didn’t do that delay on tick again 😀

[crude dew]

I did xD found something interesting though 3 dudes spawned

Only 2 in logger.

[lunar sleet]

One might not be possessed properly

[crude dew]

this is inside the Enemy BP

looks odd.

[lunar sleet]

Tough to say, multiplayer has its own different set of rules

[crude dew]

omfg... im a dumbass. xD

1 player but play as a client....

now is all working fine with no issue #shameface....

cant believe i got myself stuck like that for hours. lol

thank you so much for all the help !, Not a single one is "bugging" out now lol

[lunar sleet]

That is a common gamedev experience, getting stuck on silly things happens to all of us

[crude dew]

🙂 thank you makes me feel a bit better about myself lol 🙂

[sweet silo]

oh nice sry i went to bed i'm in france so it was pretty late ! Sure i could try that ! without timer then ! What does the "AND" boolean does exactly 🙂

[lunar sleet]

It lets you add 2 conditions together

So you can use only one branch, if your use case permits

[summer bolt]

The latter I think?

I just want it to be animated, and have th precise skeletal collision and gravity

[surreal peak]

@summer bolt https://www.youtube.com/watch?v=FK7FBBdY5fY

I somewhat think this is what you want

The start of it might not show what this is really about, but if you skip a bit to the end to see the result you'll see that the Dog has animations etc. but also reacts to physics

[summer bolt]

Ill have a look ty

[surreal peak]

Is that like an Actor Mouse Over thing?

Or are we talking UMG?

If it's an Actor, why not just replace that with your own Trace?

[surreal peak]

Widget Reflector?

Should literally be the thing to use for this

[empty wasp]

Hello guys I'm new to unreal and I want to make an app to show images from my headset on 3d environment can someone send me a link to a tutorial that shows how to set image on 3d place

[stable bane]

Hey everyone! Im currently building my first spline mesh tool blueprint and wanted to know if there is a way to switch the get actor scale 3d output based on the Spline forward axis you set in your variable.
Meaning if the user sets his spline mesh forward axis to Y, the output should also use the Y one.

[barren relic]

I'm trying to get a pawn to move left and right, I have a nav mesh and I have also tried the simple move to node but it just doesn't move.

[dark drum]

You don't specify the actor you're trying to get the AI controller from.

[barren relic]

don't or didn't

[barren relic]

still didn't work

[dark drum]

Does it print 'Failed to Move'?

[barren relic]

no

[dark drum]

Does it print the goal location?

[barren relic]

yes

[barren relic]

now it's printing

[dark drum]

The goal location probally isn't reachable. Try projecting it to the nav mesh.

[barren relic]

Is this the node? I've never used it before

[dark drum]

Yea, put the goal location in the top and modify the query extent to change how big of an area it will check to adjust. 100, 100, 100 can be a good start. The other to you can ignore for now.

[barren relic]

still failing so far, do I expand the query extent?

made it spawn an effect to show where it's supposed to be heading, and it's definitely within the nav area so im confused

[dark drum]

How have you connected it?

[barren relic]

I expanded the query extent just in case

[dark drum]

So the next things I would check is that there's definitely a nav mesh in the scene that covers the relevant area and that the pawn spawns with an AI controller.

[barren relic]

well here's the nav mesh, I have to check that ai controller though

[barren relic]

and here's the controller settings

[narrow sentinel]

I have my static mesh, is there a way to have certain collision be different to others ?

as the slope bit I want to be more slippy so the item slides down it, but apart from the I'm happy with everything else being normal friction etc

[maiden wadi]

Two things you can add to your game specific ability system component early on. First allows you to add attribute sets at runtime from BP. Second is a function that uses a runtime GE to set values. It only works on instant GEs of course since it has no static data, so it can only set values

UFUNCTION(BlueprintCallable)
void AddNewAttributeSets(TArray<TSubclassOf<UAttributeSet>> AttributeSetsToAdd);

UFUNCTION(BlueprintCallable)
void TrySetAttribute(FGameplayAttribute AttributeToAffect, float Value);```
```cpp
void UHomesteadAbilitySystemComponent::AddNewAttributeSets(TArray<TSubclassOf<UAttributeSet>> AttributeSetsToAdd)
{
    for (TSubclassOf<UAttributeSet> SetToAdd : AttributeSetsToAdd)
    {
        GetOrCreateAttributeSubobject(SetToAdd);
    }
}

void UHomesteadAbilitySystemComponent::TrySetAttribute(FGameplayAttribute AttributeToAffect, float Value)
{
    if (!AttributeToAffect.IsValid())
    {
        return;
    }
    
    UGameplayEffect* DynamicAttributeSetter = NewObject<UGameplayEffect>(GetTransientPackage(), FName(TEXT("DynamicAttributeSetter")));
    DynamicAttributeSetter->DurationPolicy = EGameplayEffectDurationType::Instant;

    int32 Idx = DynamicAttributeSetter->Modifiers.Num();
    DynamicAttributeSetter->Modifiers.SetNum(Idx + 1);

    FGameplayModifierInfo& DynamicValueSetter = DynamicAttributeSetter->Modifiers[Idx];
    DynamicValueSetter.ModifierMagnitude = FScalableFloat(Value);
    DynamicValueSetter.ModifierOp = EGameplayModOp::Override;
    DynamicValueSetter.Attribute = AttributeToAffect.GetUProperty();

    ApplyGameplayEffectToSelf(DynamicAttributeSetter, 1.0f, MakeEffectContext());
}

Makes testing a little easier early on til you get your data sorted out.

[fair tapir]

So I have to different actors of the same class placed in a scene, and they both exist in an array, but when I use Array#Find to get the index it returns 0 for both of them? Can I not use Find if both are the same class?

[dark drum]

It sounds like you want physics materials.

[maiden wadi]

Then make GEs for every attribute and use them.

[narrow sentinel]

well I have that already however I wondered if I was able to give the specific box collision a different one to others

[dark drum]

I don't believe so.

[narrow sentinel]

fairs, not end of the world just was a thought if it was possible 🙂

[dark drum]

It should work fine for multiple objects of the same class.

[fair tapir]

Hmm...

[maiden wadi]

You're only ever supposed to set attributes on the server anyhow.

You make a GE that overrides the attribute and you apply it to the target through their ability system.

[summer bolt]

The thing just like doesnt work

the phycics control does ntohing

any clue on it?

[surreal peak]

Nope, never used it

[errant scroll]

hello, im try to make the line trace start from the suppressors but my issue is when u i start shooting is start from suppressors and going left side not forward how i can fix it

[surreal peak]

Your Mesh is probably rotated 90° or something like that

You can try taking the right vector instead. Also you don't need to multiply each component of the vector. You can just multiply it by a float by changing the pin type (rightclick it)

[errant scroll]

even when i try to rotated the suppressors in gun mesh noting change

and this what component i have in character BP

[dark drum]

You could get the sockets rotation and get the x vector. Then you can just rotate the suppersor socket so its in the direction you want want forward to be.

[errant scroll]

so i get the socket rotation but what node should i use to modify the current socket rotation

[dark drum]

Actually, is the suppressor socket an actual socket or a bone?

[errant scroll]

is socket

i thing im just still learning

[dark drum]

Then select it, rotate it and save. Granted it might cause problems if the socket rotation is used for other things.

[surreal peak]

fwiw you should probably also attach the Gun to the Mesh and not the Capsule

[errant scroll]

yes i did that also not change for and also i have emitter for muzzle flash and also is attached with the suppressors when i select and rotate the suppressors the emitter it will effect by the change but the line trace is not effected

this part when i change the suppressors rotation is effect with the change

but the line trace is not effect

[tight pollen]

how can i get Post Process Materials from Camera?

[errant scroll]

same thing

[sweet silo]

ok nice !

[barren relic]

Fixed, I keep forgetting you can't use a pawn with these movement nodes

[surreal peak]

You probably can, but you gotta add some form of MovementComponent

[barren relic]

yea if I tried that I probably would have saved time

[maiden wadi]

You make a GE as a new class.

[summer bolt]

do you have an alternate idea? i cant get the first part working of this.

like someother way to do the collisiuon thing

[thin panther]

did you mean to click #cpp ? :P

[narrow sentinel]

oh yeah sorry haha

just realised where I posted this, let me move it haha

[open dune]

Hi I'm looking to implement a banking effect to my spaceship, i got a prototype working, however i can't have collisions because my ship's mesh isn't the actor's root.
as you can see from the video, the ship itself is independent from the camera.
i want to set the ship as the root and have the camera still independent from the mesh, do i create another actor as the camera and follow the ship?
note: i also want the camera to inherit the ship's roll so when the player presses Q or E to roll, the camera does as well

[thin raptor]

Having trouble with my projectiles colliding with their owner and failing to fire. I've tried ignore actor when moving but it isnt working reliably

For some reason it works when the actor is stationary, but stops working when they move

[jaunty solstice]

Trying to reproduce a Blueprint from a blurry 720P youtube tutorial.
https://youtu.be/5aqo04SmGCc?t=164
Has anyone had this challenge before?
Were you able to solve?
If I could simple read all the text I could probably figure out data types etc.

[manic vessel]

CAN anyone tell me why this is not working in my ANIM bp. I wanted to clean up and make a single function . If the socket names are hard coded It works but as a function passed it they don't?. Normally This method works for me

[lunar sleet]

Hard to tell what you actually put in the default value of those name variables, especially seeing that your socket naming convention is a bit whacky to begin with

[manic vessel]

there is no default value, as its the input values inside the function

I was trying to make it work with both hands and not have one for each.

[lunar sleet]

Ah I see you’re using the local gets

[manic vessel]

yes

normally works in my character, but this is the first time its not, is there some difference with the anim BP

its a new one for me

wierd part is it works on the grabbed bool when I attatch the hand to held items

when I let go it goes mental

I will just revert it, if it aint broke!

[copper chasm]

if it aint' broke, it probably will be soon

that's my motto 😄

[bold torrent]

I'm not sure what is going on, but today suddenly the built in lerp functions from unreal engine decided to stop working correctly?
I'm lerping between 0-100 and the alpha is a linear curve from 0-1 in both XY, the function executes every 0.01, when I print out all the values, I reach 100 at elapsed time 0.45, while alpha is still 0.45.. Double checked everything I can think off so far.

[summer bolt]

bump

[summer bolt]

Discussion is here.

(if anyone else has ideas)

[lunar sleet]

Why are you firing a lerp almost on tick lol

[bold torrent]

What do you mean?

[lunar sleet]

You said your lerp function fires every 0.01

[bold torrent]

Yes, to interpolate between 2 values, I don't understand your initial statement though

[maiden wadi]

I think he's asking why you're not simply using Tick or a Timeline.

[lunar sleet]

And also based on what you described, I’d wager you’re doing something silly like overwriting A or B while the lerp runs

Hard to tell without screenshots

[bold torrent]

Not sure how it's related to much initial question, but I initiate a timer that runs 0.01 on a loop, then I simply clear the timer when my target values are reached. I dumbed down my calculation description, I calculate a large amount of values during each iteration. The Component have tick disabled, I consider this somewhat of a micro optimization, and preference. Timelines are ugly and I don't want to introduce the overhead when I can just as easily implement a timer or tick and interpolate a curve of my own for the output value equivalent of a timeline..

[maiden wadi]

Did you check the MaxOncePerFrame setting on the timer?

[bold torrent]

The interpolation worked just last night, but now it doesn't. I'm in the cleanup refactoring state, so I guess I might have to double check if I changed the Current/Target values somewhere unintentionally, hopefully this is the case

[bold torrent]

I am not aware of this setting, is it available in blueprints?

[maiden wadi]

Yes but you probably didn't then. It's disabled by default. Also not sure if it'd matter here but hard to speculate with no logic.

What is stopping the timer? You said you're lerping between 0-100. But how do you get 100 from a 0.45 alpha?

[bold torrent]

This is exactly what has me dumbfounded. I clear the timer when the target value is reached, and I'm checking what values it output every frame and they look good, except for the output of the lerp function itself which seems to be ahead of everything else, even if the alpha input is correct

Starting frame

------------------------
[STARTING VALUES]
Update Interval: 0.01
Elapsed Time: 0.01
Alpha: 0.01
Current Socket: X=0.000 Y=0.000 Z=10.000
Target Socket:  X=0.000 Y=-100.000 Z=10.000
Bool: false
------------------------

Final frame

------------------------
Update Interval: 0.01
Elapsed Time: 0.27
Alpha: 0.27
Current Socket: X=0.000 Y=-99.999 Z=10.000
Target Socket:  X=0.000 Y=-100.000 Z=10.000
Bool: true
------------------------
``` And only using built in Lerp with the A = Current, B = Target, Alpha = well, alpha.

[gentle urchin]

Guess it'd be interesting to see the actual code behind this

[summer bolt]

Anyone familiar with blender would be good at answering, anyone know how to replicate the shrinkwrap effect in ue5 (like falttening a mesh against something). THanks.

[wind veldt]

hello everyone. is blueprint enough for multiplayer co-op game with tps? or it must be c++

[maiden wadi]

Insufficient data to answer the question.

[wind veldt]

Maybe there is someone here who has experienced this

[maiden wadi]

I do. Your question does not have enough data to answer the question.

[wind veldt]

for example think a game like devour. 4 person co op game

[gentle urchin]

Authaer is a bot

[maiden wadi]

Coop Multiplayer third person shooter leaves a lot open. What kind of coop? is it local or online? What kind of game? What are the primary mechanics like? How many players?

[gentle urchin]

You must feed it enough data

[maiden wadi]

DATA

[wind veldt]

ahahahahahaha i didnt know that

[gentle urchin]

Next gen A.I , im positive

Really accurate and human like answers

[maiden wadi]

I wish I was a bot. That would make so many things much simpler.

[wind veldt]

is he joking?

[gentle urchin]

Who knows

[wind veldt]

i believed

[maiden wadi]

Error 404: joke not found.

[wind veldt]

can i text you directly?

[maiden wadi]

You can. But I generally don't answer DMs.

[gentle urchin]

You can share details about a game without sharing details about a game

(Auth ignored my dm's for years, so get in line)

[maiden wadi]

Am watching Devour gameplay though. In general I want to say possible maybe. It looks fairly simple.

[wind veldt]

yes simple but im new at unreal engine. formerly i were developing e commerce systems but i tired i wanna develop a game thats why i dont know c++ its come so complicate as all new person

[maiden wadi]

Someone just put a fucking goat in a brazier.

[wind veldt]

so blueprint is came to me basic and simple but i saw some test videos blueprint is some slow

[gentle urchin]

Theres some gotchas but you can do quite a lot with it

[wind veldt]

that why i wanna ask who experienced about this

[gentle urchin]

Usually advicible that you do atleast some cpp for some of the networking stuff

[wind veldt]

So will this slowness cause problems on online servers If so, I dontt want to get involved in this

[maiden wadi]

Realistically it's possible with what I'm seeing in the videos. But also realistically C++ would make life much easier in some cases. I don't see this game having much bottleneck issues, there don't seem to be a lot of AI, and there isn't a lot going on in the world, it seems rather atmospheric.

[gentle urchin]

If it does, you definetly can tackle it down the line in 97,3% of the cases

[maiden wadi]

I can't imagine making a game without C++ anymore. Like I'm making this Devour game in my head in BP only and some of the handling issues hurt. Possible to do but erg.

[gentle urchin]

Guess networking deserves a special * there as doing c++ gives you far better control over whats replicated for who, when

So refactoring that can be a bigger task than other casual stuff

[wind veldt]

Yes. If you are a single team like me, I think it can cause brain damage that could lead to suicide.

thanks for reply guys

i guess learning c++ would be more good

[bold torrent]

Made some simplified logic for a screenshot to show my previous issue, let me know if you see anything that might be causing the issue im experiencing

------------------------

------------------------

[maiden wadi]

Ah. That will be your issue.

You're updating the starting point

Lerp is to know you're going from A, to B. But you're moving A closer and closer as you lerp. Which makes your distance take less and less time to get where it's going. At the beginning you need to save A, and B, and simply use the elapsed time to lerpto them. Instead of checking if A==B, check if ElapsedTime>=1.0

[bold torrent]

Derp, you are right on the money. I disconnected the update and it lerps all the way to 1.0

[maiden wadi]

To be fair on this. You don't need to spend four years becoming a master. If you have any programming background at all or understand basic logic and just need to translate it to code, you'll have a much easier time. With some persistence you can learn a ton of what you'll need for Unreal in a year.

[bold torrent]

Seems no matter how long time passes, these basic mistakes happen from time to time.. @maiden wadi Thank you for point out the issue.
Can't believe I spent 2~ hours on this without seeing it

[maiden wadi]

They happen. 😄 Glad it's working though.

[maiden wadi]

On a curious note. I wonder if the MoveComponentTo node works for this?

I don't think I've ever tested latent action nodes in a graph with disabled tick. It probably doesn't run the update I assume?

[bold torrent]

I've used the MoveComponentTo node for ziplines, but that was on an actor with tick enabled, so can't say for sure!
Unless it connects to the worlds TimerManager to circumvent the actors tick settings, it shouldn't technically work

[dawn gazelle]

MoveComponentTo uses the World's LatentActionManager's tick.

[maiden wadi]

Yeah, just tested. It seems to work at least in an Actor with it's tick off.

Would make your life a lot easier. 😄

Interestingly the Return doesn't work after it's completed. That's kinda dumb.

Ah. Cause the action is finished and data removed from the action manager. 😦 Should have been an Async node that does the same thing but maintains it's own state after the action manager is done.

The new slate postbuffers are really awesome. 😄 radial faded blur.

[spark steppe]

slate keeps crashing on me in 5.5 -_- (there seems to be a 50/50 chance when switching back to the level tab)

[maiden wadi]

I'm still on 5.4.4

[spark steppe]

what's up with all the animals? 😄

[maiden wadi]

Was testing the new anim parent thing.

Er. Templates, not parent.

I mean it is a parent, I think. But it's the neat new thing where you can use the same AnimBP even for multiple skeletons.

[lunar sleet]

I stopped downloading previews, not really worth the trouble lol

[spark steppe]

yea but 5.4 wasn't good on Linux 😦 vulkan crashes all the time

also what's up with the blur in the bottom right?

[teal talon]

Question: I cant figure out why my timer just doesnt' count. I have it set to 300 and it's in same tick just keeps going. I'm trying to use these vs delays but I don't understand why it's not working. Could I get a hint please

[maiden wadi]

Blur on the bottom right?

[spark steppe]

the box shape

[copper chasm]

Is there a better way to do this? For character creation, in the level, there's going to be the BP_CharacterCreation actor, which spawns a WBP_CharacterCreation widget (that holds all the other widgets inside of it) and then likely a Character for toggling through visual modeling. I have all the widgets grab the BP_CharacterCreation actor, to pass info directly to it when they do things and then have it dole that info out wherever it needs to go.

[copper chasm]

lookit all them cows

[maiden wadi]

What do you mean by not counting? If it's at 300. It'll simply wait 5 minutes and then run once.

[maiden wadi]

IMO this is fine as long as there will only be one.

[maiden wadi]

Still not following. You mean the corner of the cube, or?

[copper chasm]

I did this for my "GameMaster" pawn in gameplay and everything was okay, I figured it'd work in CC but what do I know (less by the day)

[teal talon]

yeah I know, but I watch it skip right past it in the blue print while I'm playing it. I dont' understand why

[maiden wadi]

Oh. I see what you mean now. The SetTimer block doesn't stop things after it like a delay.

[teal talon]

I might not understand how to setup timers then.

I assumed it was this simple.

Does it not stop and wait until done?

[maiden wadi]

For example. These are logically identical.

[lunar sleet]

What the actual fuck is that code tho lol

[teal talon]

oh...

[lunar sleet]

Event containing the timer that calls the timer who taught you this chatGPT? 🤣

[teal talon]

thank you. I miss understood this. you rok

[spark steppe]

oh, yea. i didn't notice the cube. it looked off. but knowing there is a cube... it seems fine

[woeful yoke]

I am trying to create this "Placing item on shrine" thing. Where when overlapping with pickup objects the Beam above the shrine will scale up. And if player decides to remove the item from the shrine it should shrink down. However at present the scaling up is happening as expected, but soon as I drop the item on shrine and go back its also doing the shrinking down thing. It should not do that, as the overlap is still happening since the pickup is on the shrine. How do I solve this? Please help!

[maiden wadi]

TBF I do this sometimes. Even in C++. Sometimes you just need to call the same event multiple times and start a new timer. 🤷‍♂️

[teal talon]

I'm just learning, I was using delays but then someone said those were bad, so I'm trying to use timers.

Making fun of me for not knowing what I don't know is pretty odd in a creative discord ment to help people.

Do you make fun of all new creators?

[lunar sleet]

I mean… sure. I would just have a separate event that calls the timer tho

[lunar sleet]

I’m making fun of chatGPT

Better that you’re using timers over delays at least

[teal talon]

I'm trying

[maiden wadi]

The blue area has a blur that tapers off at the edges. And it's done in a UI material. So you can have blurs on things without having to use the box shaped blur widget.

It's kind of like a UI based post process. 😄 I love this.

[random bobcat]

hello everyone , any idea how to spawn an object in a random point in a navmesh

[maiden wadi]

Get random point on nav mesh. Call spawn actor with that point as the location.

[teal talon]

Thank you so much this solved my issues. You are a super star.

[maiden wadi]

🦸 ⭐ ❗

[maiden wadi]

Out of curiosity, about your SetVisibilities there. Are you just trying to hide the entire actor?

Or show in this case.

[teal talon]

yeah it's fish bird particles I want to make disappear after you harvest it

Then after 300 they come back

[maiden wadi]

If it's the entire actor you can do a simple SetVisibility on the actor itself instead of all of the components. Less upkeep there.

[teal talon]

oh really

thats great. yeah it's a bp

I get stuck here where I can't use self and I can't seem to get the bp resources pin

[lunar sleet]

Generally you want to place certain spawn areas than just pick any random point. You can then use get point in navigable radius to add some randomness

With high enough range you could prly just use one point in the middle and the aforementioned node

[lunar sleet]

Notice what the target says. You need to give it a scene component

[maiden wadi]

Ah. My bad. Actor version is SetActorHiddenInGame.

[random bobcat]

there is too much geometry in in my map so i prefer to use Get random point on nav mesh because this object is a pick up

[lunar sleet]

I forgot that was a thing 😅

[teal talon]

This seems illogical to me. I'll have to remember this

[lunar sleet]

Which part

[random bobcat]

but this funtion does not appear to me

[teal talon]

Using a sceneroot vs the actor pin

when it's all self isn't it

[lunar sleet]

I mean for that node. See Authaer’s message on hiding the actual actor

To clarify

The node you were using is looking for a component

[teal talon]

interesting. Is there a pro cons vs these 2

[teal talon]

oh ok.

I'm coming from Minecraft Bedrock dev, so still having to figure out these logic loops.

[lunar sleet]

Well if you say wanted to hide only one mesh component but leave the rest of the actor alone, the second node would be more appropriate

[teal talon]

perfect

[lunar sleet]

Are you sure “get random point on navmesh” is a function? I would check but Epic deleted the docs so idk for sure now

[teal talon]

So if I wanted to leave 1 on as a hint where the resource was, I'd use 2nd. Makes sense. Just have to remember 2nd wants a component pin

Is there a reason why compoent pin and actor pin isn't a diff color?

That would have helped me

[lunar sleet]

Generally all ref targets are the same color. Easiest way to differentiate is to read the “Target is” part

[teal talon]

Isn't the target look the same here? Or am I missing a detail

oh the text?

[dawn gazelle]

The top of the node states "Target is ...."

[maiden wadi]

Whoever originally created these settings was not very consistent. There are two visibility settings on Components. Visibility and HiddenInGame.

Visibility is replicated so if set on server it will hide it for everyone.
HiddenInGame is local to the machine using it.

If Visibility is false or HiddenInGame is true, the primitive will not render.

Actors have a single setting called Hidden. Hidden for an Actor is also replicated and works same as a Component's Visibility setting.

If an Actor's Hidden is true, none of it's primitives can render regardless of their own settings.

[teal talon]

I've been not paying enough attention to that, and focused on the pins. Thats my bad

[lunar sleet]

The other difference between Visibility and Hidden in game is that the first one hides it in editor time too, whilst the latter only hides it at runtime

For instance I have spawn point spheres in my level that I can see before I hit play but they disappear thereafter (because I’m using Hidden in Game but Visuble)

[teal talon]

thats good to know. When I'm doing widgets it's painful if they are hidden in the editor.

I'm not sure I understand the logic of "New" Hidden. Now Hidden?

[dawn gazelle]

Here's why you can't rely on the color...
An "Object" reference can contain any type of reference to basically anything within the engine, including Actors, their Components or even assets. So the blue pin basically means, it's a reference to something. Further refining what it stores doesn't change the color, just what it is allowed to contain.

[lunar sleet]

It’s just a fancy way of saying Hidden is true

[teal talon]

thats good to know. I feel like this is a frustration point when I can't figure out the right pin to connect

[lunar sleet]

Tbh, sometimes it’s just a matter of dragging from that pin and seeing what the options are

Eventually you’ll learn what each pin is actually looking for

[teal talon]

Yeah, I'm having to build exp to learn more. Thank you so much this was very helpful

Getting my game instance setup was a big step so. I'm moving forward atleast

On a side note: How often do you if ever crash your game to the point you need to recover from a backup? I don't really want to use version controlls and just going to backup the entire projects from time to time. but I'm not sure how often this should be.

Any advice on if full crash is common?

[scarlet compass]

I think I'm very close to this working as intended but clearly missing something. The goal is to take a full list of potential owned items (fed into "current owned pieces") and check it against the current inventory ("Content") to remove rows that the player does not have at that time. Right now it only removes one row at a time rather than all of them that are not in content. Any help much appreciated

[dawn gazelle]

You'll run into problems if you're removing an index from the array while you're currently looping through it using a For Each Loop as you may be preventing the loop from continuing further. If you use a reverse foreach loop instead, that can mitigate this problem.

Based on what you have in your code, this may be the problem you're facing. Your loops should otherwise be removing whatever is contained in the BPC Piece Inventory's Content array from the Current Owned Pieces array if the names match.

[scarlet compass]

Ok I will try the reverse then thanks!

[barren tangle]

hey i'm using the node GetRandomLocationInNavigableRadius and it return only 2 positions

i can see the nav bound

on all the surface. but the function return only 2 positions

[sweet silo]

h

[maiden wadi]

What do you mean by it only returns 2 positions? As opposed to what?

[barren tangle]

i was expecting to have a random location inside the green area

but it's only returning the same position

[maiden wadi]

What is calling this and printing these?

[barren tangle]

this, it's inside a timer

each second

[maiden wadi]

The actor is that thing in the middle?

[barren tangle]

each second i'm search for a random position

yes

i put it into the center of the map

i have reduce the timer

i set 0.1 sec

and i can see that

it spawnin at rondam location but not all the time

most are on the same location, and after some random reason it spawn somewhere else

the full blueprint of this spawning actor is that

a timer by event (looping)

and a getRandomLocationInNavigableRadius

I put 5000 to be sure to cover the level

and i spawn at that "random" location

and print the position where i spawn

[maiden wadi]

That's odd. I can't repro it. 🤔 Your navmesh looks fine.

[maiden wadi]

What is the map location of your spawner?

[barren tangle]

i move the navmesh volume to see what happend

lot of spawn but only at 2 locations

[lyric basin]

It doesn't add them together, it checks if both conditions are the same value, namely if they are both true. If they aren't, then it evaluates to false.

[barren tangle]

is there i kind of timer inside the random function?

[lyric basin]

It checks if both the bool inputs are true and then evaluates to true if they are and returns that value

[maiden wadi]

No. Usually the cases for this are because the origin is outside of the nav area. It'll default to the origin in that case. But your origin seems fine and in the nav area. :/

[barren tangle]

yes i have checked and it's inside 😢

[sweet silo]

thanks i'll try the solution now

[maiden wadi]

I dunno then. 😦 I can't seem to replicate it. I get very random placements.

[lyric basin]

When I get to my rig tonight, I can make a mock-up for you for what's in my head

It's hard to explain

[copper chasm]

I wish there was an easier way to get to my gameplay tags

[barren tangle]

mmm same code as me?

[maiden wadi]

Correct

[maiden wadi]

How do you mean?

[copper chasm]

This is the whiniest whine I have ever whun, but clicking into project settings and then tags and then opening the editor

I know I could do it in notepad, I know I can drag it to another monitor

[maiden wadi]

Lol, fair.

[copper chasm]

I decided this (my 9th) copy of the project is do or die, cause I'm getting behind re-hashing everything, so I'm going very slow, I'm commenting every bit of BP and marking it red or green for whether it's locked in or not

so far so good

[maiden wadi]

Should get yourself some source control. So you can make big changes and revert easy if they don't work out.

[copper chasm]

I really ought to, I had it all set up when I was doing C++ because I knew what I was doing with Rider

I'm not super confident in setting it up in the editor, I should go look

my big thing is, ttrpg players will play a game that looks like dogfood if the data is right and the gameplay is tight, so I just really have to make sure the options are there and are doing what they're meant to

[maiden wadi]

I just use azure devops and GitDesktop for personal stuff. Served me well enough so far. I really should learn Perforce at some point though.

[maiden wadi]

👀 My dog's food looks better than mine most times.

[copper chasm]

man, my cats get like a ground up powder mixed in with their canned wet food and some hot water, I spend more time feeding them than I do making my own mac and cheese some days

they're the whole reason I got into gamedev, I made a little silly 2d pixel platformer for the wife so she could play while she was at work, drew all 3 cats 😂

[maiden wadi]

Some days I wish I had went with a simpler engine for simpler games. Probably not as bad if you're not a generalist but learning Unreal certainly is a task.

[copper chasm]

So I have a custom event in my BP that just establishes binds from all the widgets. It's getting pretty long, can I just run a sequence off the event instead of looping my exec lines back down and around?

I don't see why not specifically

but it's going to be like 30 boxes long by the time I'm done and I'd like to make it neat

[maiden wadi]

I usually just add a call right after the bind with the desired inputs.

[copper chasm]

So like, there's an Actor that creates a "hub" widget where it's the canvas panel, 4 buttons, a widget switcher with 4 widgets, and the character sheet widget. My plan rn is to have the widgets in the switcher update the Actor through event dispatchers, and then the Actor will update the character sheet widget where needed, and then on finalization, the Actor will create the character with all the variables it got from the widget switcher widgets (word spaghetti)

So the Actor is basically a ton of "assign event on XYZ" and the widgets themselves get all the info and pass it through on calls

but eventually all them assignments are gonna get looooooong

I can just drag the pins down and around and reroute to make it pretty, but if I can also just sequence the binding event, 1 for each widgetswitcher widget

It should still fire them all anyway?

[sweet silo]

any idea why i have zero prinstring?

[dreamy mountain]

hey, im making a shotgun using projectiles, but it keeps firing in one specific direction instead of where the player is aiming, does anyone know of a fix? im following a tutorial from my college tutor but i think someone deleted a few slides on the tutorial, so its missing info and hes on a week leave, so i cant really ask him; my friend said he fixed it with like 3 or 4 nodes but doesn't remember which. any help would be great, thanks

maxAngle is set to 70 at the minute

[maiden wadi]

IMO I would avoid this. Let the widgets just get the actor and call functions on it when you want to change something. Let the widgets also bind their own updates when the actor changes, or just tick their values. No need for the dispatchers to update the actor.

[dreamy mountain]

and the muzzle is a scene component, this oen

[copper chasm]

Sounds like I’m doing it the exact opposite lol

[maiden wadi]

In general, always consider UI as a layer on top of your gameplay. Gameplay(your customization actor) shouldn't care about the UI. You should be able to drop that thing in a level and set it up from slash commands if you wanted to with zero UI. UI is nothing more than a display for the values on the actor and an interface to make the calls to change the values on the actor.

And true is pretty much for any game UI.

[maiden wadi]

This all seems fine. How are you moving the projectile? Projectile movement component, or simulate physics?

[mild ibex]

Question, when loading sub levels as level instances, is there a reason the lighting scenerio doesn't load with the sub level?

[dreamy mountain]

projectile movement id guess?

[maiden wadi]

Can you open the Projectile BP, click the PMC in the components list and past the settings under Projectile in it's details panel?

[dreamy mountain]

https://i.vgy.me/sCNiFm.png

[maiden wadi]

Checkbox the InitialVelocityInLocalSpace

Then try shooting again.

It may constantly shoot to the left of the gun?

[dreamy mountain]

that it is

yeah

im guessing thats to do with either placement or the maxangle variable

[maiden wadi]

Rotate your Muzzle so that the red arrow is facing forward.

[dreamy mountain]

woo

that worked

[maiden wadi]

X(red) is forward backwards. Y(green) is right left. Z(blue) is up and down.

[dreamy mountain]

gotcha

what about reducing the spread? im guessing thats where the maxangle variable comes into it

the tutorial he gave us was mainly to compliment the class where he went through it

partially my fault for not listening to him

[maiden wadi]

Yeah your max angle should affect that given the code above.

[dreamy mountain]

love it

thank you very much

[maiden wadi]

💯

[dreamy mountain]

thats what i got in the end which is exactly what i wanted

[maiden wadi]

Nice. 😄

[sweet silo]

so im launching a vessel into space and seeing if it's colliding with something after some seconds

but i never get to see "Has timer completed" being printed

[faint pasture]

Why are you mixing timers and delays and tick

[sweet silo]

idk i was looking for a way to do a timer inside a timer

[faint pasture]

What should this code DO?

what is the actual mechanic

[ionic quiver]

When using a scene capture 2D node. Is it possible for it to only capture a component of an actor, or only a specific material (wherever it may be).

[sweet silo]

it's supposed to start a timer => the capsule starts moving
and then i wanna know if the capsule is touching anything before the 5 sec countdown is over
If it has touched => player lost @faint pasture

[lunar sleet]

Yes, that’s what I meant. Obviously I didn’t mean addition lol

Also if we’re being pedantic, your first sentence is incorrect

Cause if they’re both false it doesn’t return true 😛

[woeful igloo]

the primary is the setup, kind of like the struct, the asset is made with the primary as the base.

a variable would use the primary, able to pull any of the assets tied to it

[fickle rampart]

Using timer in such a case can be tricky. You want to check for collisions within a timespan? Timers are mostly meant to trigger logic "after" a given time. Like toggle a boolean variable.

So what you should focus on more are TickEvent, HitEvent or Timelines instead. Those are meant to execute logic "within" your specified timespan. Especially for stuff like collision checks.

You can e.g. use a Timer to handle a boolean "CheckCollision", disabling it after timer ends. But the checking logic should be done in TickEvent or through HitEvent for as long as "CheckCollision" is enabled.

Worth to note that the usage of HitEvents depends on your Actor's setup in terms of collider and how you set them up.

Alternatively, it is also possible to use a timeline which doesn't need a timer or complicated countdown logic. Just start it and let it execute the check colision logic through its update-node. And since the logic happens in an actor, timelines can be used for sure.

Some more advanced knowledge about Timelines:
Every timeline you "add" into your actor's BP will be added as a variable. The variable then can be used to alter some values in it, e.g. its "duration" before you trigger it. Furthermore, timelines do not need "curves" at all if your goal is a simple "execute for given duration" stuff. The curves are only usefull when you need a relation between time and given values at a specific point in time.
So in your case, just create a timeline, set its duration, trigger it and let it execute logic through its update pin.

Edit: Updated my text due to @faint pasture 's info regarding the possibility to use HitEvents of an actor's collider in combination with timers.

[maiden wadi]

@woeful igloo A Primary Data Asset simply has the ability to be loaded through the asset manager easily and has bundling support. Beyond that there isn't a huge difference. They house static data.

[woeful igloo]

ah, thanks for the correction

[faint pasture]

with hit events you can still use a timer

??? -> start timer
Timer -> print the number -> decrement -> if bTouched and number == 0 -> do the bad thing
Event Hit -> btouched = true

the "ticking" would be handled for you in the collision system, it'll let you know if a hit happens through Event Hit

[woeful igloo]

hah, know that feeling

starting to get the hang of things though

[fickle rampart]

You are right. I've updated my text after you mentioned that. Thx.

[lyric basin]

If they're both true, it evaluates to true. The other two combinations evaluate to false. I said it namely checks if they are both true, so not sure where my sentence was incorrect... Not being pedantic, was just stating that it doesn't add them together.

Comparing and adding are two different things...

[lunar sleet]

As in adding the 2 noodles into one that checks if both conditions are true, but alas, bigger fish and whatnot

[lyric basin]

Tomato tomato

[crystal wharf]

Could someone help me build a sound alert system? I'm having struggles trying to figure this out

[lyric basin]

something like this might work, probably need some tweeking, but it gets the idea across

[ionic quiver]

For some reason this works correctly in editor, but when packaging it always returns true, as in it doesn't find a match. Anyone know why this would behave differently in editor vs packaged?

In the package it even finds them by name during this. The pink is what it's finding inside the blue. So odd as again, it's completely fine in editor.

[dull kraken]

any way to trim an animation? I want to move the start position forwards by some frames.

Can anyone help me out with the "project world to screen" node. I've used it in previous projects with no problem but with this new project it works as expected when playing in editor but when I test it in a new window it always returns false with the coords 0,0.

[ionic quiver]

It seems the Find just doesn't work at all in a package or something. I tried it even as just integers. Confirmed matches in editor and doing separate print strings in package. But despite seeing matches in package it still doesn't recognize them. Really odd.

But this is only a problem on first load. Afterwards it works fine.

[rotund ruin]

WHY does my control rotation spaz out whenever I use a calculated location for the mouse in the world, but NOT when I use a standard trace under cursor? any ideas?

[jolly delta]

hi, is there any way through bps that I can "project the view" of the camera onto the plane succh that it looks as if it is a mirror ( ik there is an another way of making a mirror but I was curious whether is it possible using this idea )

[gentle urchin]

Render target

Relatively expensive

[jolly delta]

thanks

[spark steppe]

planar reflection (also has to be enabled in project settings)

and it gives way more accurate results than what you plan to do (been there, done that...)

[tight pollen]

how can i optimize it more?

[spark steppe]

you can't

[tight pollen]

so is slate:drawWindows so expensive?

[spark steppe]

that's probably the editor anyways

at least a huge chunk of it

[surreal peak]

Profile in packaged builds if you want more accurate numbers.

[spark steppe]

and if you want further advice you have to show us methods which take a long time

just from these profile chunks it's hard to tell what's even going on

[tight pollen]

I think rest is editor

[surreal peak]

Yeah then it's all fine.

Don't profile in the Editor for stuff like this.

[spark steppe]

and 20microseconds of that is your widget

which is 0.002%?!

wait, i can't math

[tight pollen]

I don't know if I can optimize it any more

unless I turn off the lights and make them worse

[surreal peak]

0.00002s

[surreal peak]

That highly depends on what you are actually trying to optimize

[tight pollen]

I use lumens, on a computer with GTX 1660 ti I have 30-40 fps

[spark steppe]

well, i'm surprised that you get >30fps

so be happy!? 😄

[tight pollen]

😄

maybe after switching to 5.5 it will be good

[surreal peak]

There are two to three stages to optimization:

• Large chunks that take a lot of ms cause they are really unoptimized
• Small chunks that don't take a lot of ms but help to improve overall if you resolve them
• Tiny chunks that add up due to existing 100 (or a lot more) times (e.g. 0.01ms alone might be okay for doing A, but not if A is done by a 100 Actors per tick, then you are back at 1ms cost)

[tight pollen]

and use megalights

[surreal peak]

For CPU at least

[tight pollen]

just for the processor I think I optimized it to the limit

[surreal peak]

The first one is easy to fix and make out, the other two are a pain, especially the last one, because it's not always instantly visible if you don't have a profile that has 100 Actors doing it.

[surreal peak]

I assume via C++?

Cause BP-only has a very shitty limit

[tight pollen]

so not, only BP 😄

[surreal peak]

We recently moved A LOT of designer and animator code to C++ which improve CPU cost by a ton, even though the actual logic didn't change.

If you start optimizing you'll start learning that all the peeps that say "BPs are slower than C++" were right.

[iron idol]

anyone have any idea why this specific bool is not saving?

[surreal peak]

And all the ones that tell you not to worry and that BP-only totally works never had to optimize a bigger game.

[surreal peak]

Not marked as SaveGame ?

[iron idol]

huh?

[tight pollen]

but basically everything that needs to work on Tick is worth optimizing

What do you think?

[mild jacinth]

if I cannot find bind event for a dispatcher from Find In Blueprints window, does it mean its not actually binded anywhere at all...?

[iron idol]

I'm not sure I follow

the other variables seem to be working fine. Its just this one bool for some reason.

[tight pollen]

I know, it also depends

[surreal peak]

You have a SaveGame Blueprint. In that you have the Variables. Did you set the Variable to be a SaveGame variable in its details?

[iron idol]

i take it you are talking about the save game box in here

located in this guy

If so none of the other variables that are saving have that box ticked. and when i ticked it and tested, it still didnt save

[quick imp]

Does anyone know why whenever I try to do anything in my game, it seems to reload the world? Or what I can do to troubleshoot this?

[hushed orchid]

are you spawning the character from controller or game mode ?

[quick imp]

GameMode

It seems the game reloads after I try to interface to an actor component

Does this happen to anyone else?

[tight pollen]

does it make any difference, e.g. keeping a reference to 1 actor in 100 actors, or keeping 1 reference in ManagerActor and if necessary getting that reference from that Manager using Interface

[frosty heron]

not to me

[iron idol]

its kinda hard to make out what you are saying exactly. The gif shows you walking forward then shifting back. I assume this is what you are talking about. But then you run forward and jump.

[frosty heron]

everytime you talk about optimization it sounded like a really useless stuff that you shouldn't be worry about

[tight pollen]

thanks

[frosty heron]

a reference is just an address, at least in cpp. Int32

[quick imp]

yeah a bit hard to tell. I put a print string within the event beginplay that says world loaded. You can see it in the top left corner.

Essentially, from what I can understand, whenever I do anything that calls on an actor component. It seems to reload the world.

[hushed orchid]

can you show your world settings

i think a character reference is there and hence it is spawing in world and then game mode again spawns maybe ?

[frosty heron]

@quick imp do you have Open level node somewhere?

[frosty heron]

open a blueprint, ctrl + F . Type open level then hit the binocular button

[quick imp]

nothing lives within the level blueprint but the print string on event beginplay

[hushed orchid]

ya, u can put default pawn class to none as game mode is spawning

[quick imp]

Its nothing to do with spawning I know that for sure. It's whenever I call an interface to an actor component. In all my years, never seen this issue.

[iron idol]

is it a fresh project>

[frosty heron]

never experience the same thing

been working on multiplayer project for months

[hushed orchid]

maybe if you can explain about the flow, someone here may get an idea

so, its not that after few seconds, player respawns but it respawns only after calling interface ?

[quick imp]

Yeah, so here's an example. Within the player controller I cast to my parent player character and then message an interface that is attached to the PC. Then pass through a reference from the cast into the interface message, (may rework the reference to call on parent from within the component, but that's a talk for another time). Then from the event perform action, it calls... well the custom event. For this one, its just fire a simple projectile.

[quick imp]

Yeah, only when an actor component is interacted with.

So I disconnected my double jump, and only left the fire projectile code. I can walk around just fine, but once I press left mouse button, it reloads. As you can see in the attached video.

[quick imp]

As fresh as a first person template with the thirdperson template added in, can get 😅

[frosty heron]

why is the target null?

Try to disconnect the spawn First Person projectile

isolate the problem first

see if that still restart your world

[quick imp]

Well those two variables arent really that imporant. They just were reconnected after a few test of my own, trying to figure this out.

[frosty heron]

disconnect the spawning node

see if that's the reason why you get booted out

[quick imp]

yeah thats what I did before. Whenever I disconnect the spawner, still does the same. Whenever I unconnect the message interface inside the player controller, then it doesn't do the reload.

[frosty heron]

from what I can tell anyway, you get kicked out from the world.
The last print doesn't say Server / Client

probably worth, checking your logs

[hushed orchid]

my thoughts are , maybe its spawning but due to collision and location reference is null, its spawning near to character which is making character jump back or sort of .. ya step by step please connect and see logs .. here target is being used for spawn transform but null is being sent, that is where the whole problem is what i am guessing

[quick imp]

Yeah it seems to load into a standalone world

[quick imp]

yeah I was thinking of something similar, but whenever I try to test with my double jump ability, it does the same. However, I just learned that even if I try to cast into the actor component, it does the same. So it seems to only happen when i try to call on any code from within the component.

[frosty heron]

is your component sets to replicate?

print screen the setting

[quick imp]

Oh, I havent thought of that. I guess I just assumed it would pass through from the parent. Let me test that.

[frosty heron]

It's per component basis, click your actor component and make sure it's set to replicate

can't be calling RPCs or make variables replicated without the component set to replicate

[quick imp]

Yeah, its still not working. However, I now believe their is another layer added onto this. When I play in standalone mode, everything works without issue. But in client mode, it stil has the issue. Even after checking replicate component.

However, if I clear out all the code, and just create an empty component, it works... So I has to be something with calling Run on server or multicast.

[frosty heron]

you can get booted out from trying to do RPC on something you don't own maybe

[quick imp]

yeah that has to be it

[frosty heron]

I know it happend to some people, but I never experience it my self

[quick imp]

Fair enough, first time seeing this

[frosty heron]

for one, you need ownership of the actor to call a Server RPC

but if it's an actor component attached to the player, maybe you don't need it?

ask in #multiplayer

you skim through the logs?

it should tells you about the reason you get kicked out from the world.

[quick imp]

Yeah, I'm gonna drop that question in the Multiplayer chat. I haven't checked the logs, I need to find where those are first.

Found it, checking now.

Figured it out. When the actor component was dynamically created and attached, it wasn't created with the server's authority. So when the character tries to call the component and execute code from it, especially an RPC, it would kick the player out of the server, and the user would load into a standalone world.
The resolution: you run the create and attach actor component through a custom event multicast.

TBH, not sure if its best practice, but it works. I can also go back and refactor later. 🙂

[frosty heron]

👍

curious on how to spawn actor component at run time anyway

do you just spawn on server and client will get copies of it eventually?

[quick imp]

Well Im sure there is a more proper ways to do it, but I just run the code through a multicast custom event.

My code starts here

Then on one of the sequence executes it does this...

Would should the whole thing, but its a large amount of code.

[frosty heron]

Running delay in mp setting kinda give me heart attack

you should rely on RepNotify

[quick imp]

Yeah, sadly, I'm not that advanced yet. And not sure how to go about doing that. 😔

[gentle urchin]

Learn it sooner rather than later

Its rather vital

[quick imp]

Its not for this instance.

But it does seem insteresting, could apply it in some places

[dull kraken]

Ive got two pawns that can be possessed, i play the game, and can control the player, but is there a way after pressing f8 to possess the other pawn while in the same running instance?

[jolly delta]

okay thanks

[barren relic]

hi I'm trying to set up falling through platforms by holding down and pressing jump, is there a way to only look for the down input from the controller/ keyboard or do I have to make individual input actions for each direction? On controller I can't see that being feasible if I'm not using the D-PAD

[maiden wadi]

I feel like you should approach this with less of a controls mindset. You're on a platform and you need to fall through it. This is more of an "ability" than anything else. Regardless of input this should be a basic thing to make your pawn not collide with platforms until they've fallen through the one they started on when this ability was triggered. Your controls should simply be a chorded action where down is held and jump is pressed to trigger said ability.

[barren relic]

what im really asking is how do I get the down input from the move

[maiden wadi]

Ah. As in only that from the 2D Axis

[barren relic]

yeah or the S key

[maiden wadi]

I was thinking like a crouch button originally. 😄 I'd maybe drive that off of the look's direction value in this case. Unless there is a way to mirror controls and you could make an invisible IA mapped to the same thing as look down. But your look probably moves some vector or something or can set a direction you want to look. If it is DotProduct(Down, WantedLookDirection) > 0.5 allow the action?

[barren relic]

good idea, I'll link it to a crouch button and for the thumbstick i'll try that

nevermind I didn't know this was an option. silly me

[maiden wadi]

Btw random question on that. How are you doing the falling through platforms? Are you just setting the collision off until it falls for a short time, or?

[barren relic]

following a tutorial and I'll show you

it's working if I use the crouch action but not the fall action so I did something wrong

seems like the jump is taking prio over the fall which is strange because I was told I had to reorder them for priority and I have already done so

[maiden wadi]

Won't this also pose issues for other things on that platform like other enemies?

[barren relic]

yeah but I don't know a better way to do it at the moment

tutorial is from 3 years ago so

maybe I should make a new collision channel for those kinds of platforms and change the player's collision when I press the button instead?

I clicked on "open full blueprint editor" on the top of the screen. how do i revert it back to just a data only blueprint?

[maiden wadi]

Go to the content browser where this class is and right click it and select AssetActions, and Reload. Alternatively, restart the editor.

[storm solar]

thanks!

[storm solar]

one other question i have.
I have a third person character that has a BP component called attributes.
When i open a child of third person character, I cant see that component unless i open it in full blueprint editor.

[unborn maple]

i have a issue where this does not close and open a widget visibility even tho it being called when i add a breakpoint the key press is also being called. any idea on what it can be?

it work before i added a second game mode for the main menu now it just broke everything.

never mind i got it working i had to remove from parent on is valid node.

[maiden wadi]

There's no difference to a full Bp editor or not runtime wise. Data only is just a helper screen to set values on the subclass easier.

Hi I'm new here and need help I'm new to blueprints and i followed youtube videos to create what i do have and I'm planning to study what everything does after i fix this final issue, my character keeps jump when falling from a certain height and I'm clueless on how to remedy this. I hope this video loads so you can see my issue also here's some screen shots.

If some one could take a screen shot of how to fix my issue in blueprint form I'd be very grateful

[frosty heron]

You are stuck on jump start loop

You want to go from jump start to jump loop to jump end

Using time remaining ratio.

Look into third person template

And just copy the setup

I don't know what video you follow but the third person template got what you need

[primal hare]

Is there an event that triggers when player starts falling?

Trying to kill player if falling more than certain seconds

[maiden wadi]

Their movement mode in the CMC changes to falling. So you could bind the movement mode changed, start a timer if == falling. Remove the timer if movement mode is something else.

[primal hare]

There is this but this triggers when player spawns

[primal hare]

so event would be tick?

[maiden wadi]

No, you have the right event above.

If NewMovementMode == Falling start a timer for n seconds. Save a handle from the set timer node. If NewMovementMode does not == Falling, use the handle from the timer to clear and invalidate it.

When the timer finishes, kill the player.

[crisp turtle]

I didn't want to use the third person template I want to set it up myself so I can learn the third person template doesn't have the animation blueprint I've been stuck on this for 3 days does anyone have a screen shot of a fix

[thin panther]

Yes it does. Learning from the third person animation blueprint and how it's set up is going to be doing the same thing for you as someone sending you a screenshot of what to do.

[crisp turtle]

I've looked through the third person template couldn't find the animation blueprint, if it's there I really can't find it.

[thin panther]

I've literally just shown you where it is

[crisp turtle]

Sry message wasn't showing, I found it, don't understand it lol bit I found it

I'm looking just on how to set up falling

[steady night]

ive got a "lock on target" im updating the actor rotation towards the locked target every 0,01sec

https://gyazo.com/0c71a8a6728cea1dc84a91b3c1a12e9d

but its glictching the camera like crazy

ideas :/ ?

[crisp turtle]

Nope still doesn't work dk

[kind estuary]

The character movement component is lowering me to 50 fps when used on around 80 characters made of cubes.
Is this normal? Should i make my own APathfinding ?

[lunar sleet]

Look into optimizing the CMC first

You can try switching to navmesh walking and see if that helps, tho it has its downsides

[earnest vigil]

Anyone know how to rotate just an actors mesh so I can align the front of the mesh with the forward vector? Ive got a drone and the forward vector is pointing out of the side of it and when I rotate the mesh it rotates the vector as well

[maiden wadi]

Pathfinding is only part of the issue. It won'y consistently lower your FPS unless you're calculating a new path every frame. Usually this doesn't happen.

Most of what causes issues in characters are lighting problems with dynamic shadows on your GPU, or paying the costs of scene component updates when moving on the CPU.

[crisp turtle]

I still can't get my character to stop jumping while he is falling

If I have a data asset with an item that has a name, and I change the name of the item, will this change be reflected in all other references to this item?

[empty marten]

Hey peeps,
Does anyone know how I can get the distance between the mouse cursor and a widget? I'm trying to set it so if the cursor is x distance or closer, it affects the opacity of the button.

[maiden wadi]

The whole button at once, or like in a radius from the mouse location?

[maiden wadi]

What is the item in the data asset?

[last jolt]

Hello, i have problem that occurs when i spawn niagara that should be attached to Skeletal Mesh Component. Niagara actually is spawned on camera location, and weirdly enough there is always a camera looking object that is connected to mesh. As you can see what is highlited is one object, that has both original mesh, and camera. The attachment is never setup in code, nor in blueprint, not even in niagara spawning code either. Melee weapon class follows the same logic of using niagara, attaching niagara to Static Mesh, and it spawns in right place. Is there a possibility of connection between Skeletal Mesh Component class and Camera Component, that I could miss? I would really appreciate help 🙂

[tawdry walrus]

Another data asset has an ID.

[empty marten]

The button itself. Just wanna make it so that if the cursor is like 100 pixels or less the button fades in and then when outside that distance, it fades out.

[maiden wadi]

Then it should. The only case where it will not is if you have copied this name somewhere. If you're always pulling it from the data asset directly it will always update if you change the data asset.

[kind estuary]

thanks though im quite sure that when vinterping planes it doesnt affect performance even with a thousand planes it goes 120 fps.
but 70 planes moving by Simple Move makes it down 80/90 fps

[maiden wadi]

Is your button itself a userwidget already?

[empty marten]

No. The button is inside a widget.

[sweet silo]

That is really amazing info thanks a lot ! i have to read it many times to be sure to unredstand !

[maiden wadi]

Maybe something like this? Untested

[mild ibex]

I have an issue with timers in a function. The way I understand it is that functions are able to run in parallel when triggered multiple times. I have a map of int | struct that I'm using for this task and what I should see is that when triggering the function my static mesh moves around the curve, and this does happen, but the problem is it only happens for one mesh at a time and I dont understand why. I have the timer and the "current time" in the struct so its mapped to the proper key but when playing 1 then triggering another it will null out the prior monitor that was playing.

[lunar sleet]

Multi-threading is not really a thing in bp, aside from a few async nodes. If you call a function multiple times it’ll just fire sequentially

What you can do in parallel is instancing

Like firing a function on a class that fires at the same time on all its instances

[empty marten]

What is that node before the make box? Not familiar with it.

Never mind. Got it.

[empty marten]

I don't have the Find Closest Point on Box node even with context sensitive turned off.

[kind estuary]

This is just plain Character with just a Static Mesh (planes). 300 characters of planes cuts the fps down to 50 fps

This is what is expected, or im missing something?

This is why i always used vinterp.

[lunar sleet]

But like

Are you actually profiling

Or did you just assume it’s the CMC 😀

[kind estuary]

Its the CMC because if i use vinterp the FPs is good

this is a plain project just to test the CMC

[lunar sleet]

Did you try a pawn?

[kind estuary]

Not today. But i tried it in the past, it was similar

it was a bit better

maybe its my pc ?

But from what i read. Unreal wasn't made for many characters. So this is kinda normal?

I think i will do again a Tile Based a pathfinding for this project

I kinda wanted to go at least once with the native tools. But it seems thats only for FPS game with few characters

[lunar sleet]

When you get in the hundreds, some optimization is required. Like I said, start by changing the movement to navmesh walking instead of walking

[kind estuary]

this one right?

didnt affect anything though

[lunar sleet]

No

Not that

Well actually idk what it’s called in 4.0

In 5.0+ it’s a drop-down

[mild ibex]

that seems to be the case, however I assumed a function taking different structs would be fine, because there arent any pulic variables being overwritten

[wraith haven]

Hey everyone, I’m working on a game mechanic and could really use some advice on how to tackle the next part. Here’s the full breakdown:

What I want to achieve:

1.    Pick up parts: I want the player to be able to pick up different parts (let’s say components for a circuit board).
2.    Zoom in to the circuit board: Once the player is near the circuit board, they can press a button to zoom in and get a close-up view.
3.    Placing parts on the circuit board:
•    I want specific spots on the circuit board to be highlighted in red to show where each part should be placed.
•    When the player clicks on the highlighted spot with the correct part in their inventory, it should:
•    Place the part onto the board.
•    Remove the part from their inventory.

What I have done so far:

•    I’ve implemented a camera zoom mechanic where pressing E moves the camera into a close-up view of the circuit board.

What I need help with:

•    How should I handle the mechanics of:
1.    Picking up the parts (adding them to an inventory system).
2.    Highlighting the correct spots on the board in red where the part needs to go.
3.    Clicking on the spot, placing the part, and removing it from the inventory.

Any advice on the best way to handle this, including any existing systems I could leverage (like inventory systems or interaction systems), would be awesome!

Thanks a lot in advance!

Hi ! I have several events happening one after the other and repeating
How good of an idea is it to do a "BP_EventsUnfolding" ?

[lunar sleet]

It’s fine

[sweet silo]

thanks 🙂

[finite hearth]

Can somebody verify my understanding of event dispatchers?

I have an actor: BP_Resource
I have two unit actors: BP_Unit

• Unit1 starts harvesting BP_Resouce, it binds to dispatcher "ResourceCollected"
• when ResourceCollected called: StopHarvesting
• Unit2 starts harvesting BP_Resouce, it binds to dispatcher "ResourceCollected"
• when ResourceCollected called: StopHarvesting

When BP_Resource's HP < 0, then call "ResourceCollected"

Q: In this context, wouldn't both units receive the call and shouldn't both units StopHarvesting?

I'm finding that only Unit1 gets the call, while Unit2 will continue to harvest.

Hello! I'm having a problem with StaticMeshComponent collisions, anyone knows where the problem could be? I uploaded a video showing the bug https://youtu.be/1DFIrbz8_vs

[lunar sleet]

Watch the pinned video on bp comms, it has a section on dispatchers, if you haven’t

Are these units both instances of the same class?

[zinc depot]

this is my pick-and-drop object blueprint for "the fps" controller! the problem is when I drop the object the first time and try to pick it up it works fine. but the second time its position changes. It snaps below the original position and onto the camera inside the camera. The first time working fine but as I pick up again and again it snaps inside the camera

[chrome crag]

Is there a case switching node for booleans? I have three diff booleans in my WBP and want different outcomes based on which one is true

[finite hearth]

Both units are an instance of the same class. I think I traced the issue to an unbind all events node that should have been an unbind event node.

[ripe sun]

This?

[chrome crag]

Yes If I have three boolean values how does that get hooked up exactly?

[ripe sun]

Like this?

[lunar sleet]

You might be better off using an enum and a switch

[lunar sleet]

3 selects seems like a lot

[chrome crag]

Hmm I see

Yah i was wondering if that was even better than a nested if statement or not lol

[lunar sleet]

There’s usually a better way than a nested if, beyond 2 conditions or so

[chrome crag]

basically its If isPerfect = 100 score, isGood? = 50, isMiss? = -10

the boolean value comes from the WBP which ive casted to beforehand

[lunar sleet]

Make an enum with 4 values: None, Perfect, Good, Miss

But I mean ultimately the select is fine too

[chrome crag]

Is there any performance benefits with using this versus nested Ifs or is it just more Blueprint cleanliness?

[ripe sun]

A select node doesn't take a lot of time, 0.000001 ms or something. There isn't a noticeable performance difference.
If the performance is the same, write code that is more clean/easy to write. I recommend you watch this video about premature optimization: https://youtu.be/tKbV6BpH-C8
This blog talks about how blueprints can become expensive because of pure functions: https://celdevs.com/unreal-engine-and-the-hidden-pitfalls-of-blueprints/

[mild ibex]

feel like im losing my sanity, I just want a blueprint to move an object from point A to point B along this spline. BUT this spline ONLY goes counter clockwise. And once it reaches the beginning or end it will not loop. I can get it to follow the shortest path from A to B but it will not go from max spline length to the start without going all the way back around the spline.

[ripe sun]

Can you show some of your code?

Is this a and b?

You want it to go clockwise?

[mild ibex]

I'd like it to be able to go either way and just determine the shortest path.

[ripe sun]

Shortest path between what?

I don't quite understand your question

[mild ibex]

between distances, Point A and B are input by user. This is also converted to degrees based on spline length. So rather than entering 5,000 it could be 180° but going from 25° to 360° I'd expect it to go clockwise. But it goes counter beecause that's the spline path.
I have tried coding it so that when distance is < 5° or something along those lines it snaps to the other side but that doesnt seem to work either.

[ripe sun]

uh, is the shortest path limited to be on the spline?
