Go back to Get Player Controller (0)

This is in the game state, which doesn’t have a great association with a specific player

[maiden wadi]

Ah. You said that was a widget. Yeah you'd need to get the player controller globally then.

[fathom hazel]

oh, no this is a function in the gamestate. Sorry

[fathom hazel]

hold on, before i do this i wanna ask the correct way to go about this.

The game is about collecting cats. (ex. going up to them and pressing E. I have the HUD which i have text of how many cats are left. Considering the gamestate is meant for storing the state of the game (ex. cats remaining). The whole interact thing is through an interface, and inside the actual cat actor it sets the cat to found (and is then supposed to communicate to count down by one and change hud). I assumed the whole keeping count of how many cats remaining would be in the gamestate no?

whats the way to go about this?

as well, this will be annoying but eventually i want to make a hint system where one of the cats remaining makes a meow sound to help the player find the cat. Zero clue how to go about that as well, but thats a later issue. Not sure if that affects how we code it now.

[maiden wadi]

Realistically you'd keep that actual count in the GameState as an integer. And have a setter function for it that first sets the new count and then broadcasts a delegate(event dispatcher).

Your userwidget's Construct could then GetGameState->CastTocCGameState and both set the text initially and bind a delegate to set the text when that delegate is broadcast.

In this way your GameState doesn't have to care at all about the UI and your UI can just listen and update when the GameState says it's changed.

[fathom hazel]

as an int, not a float. Got it.

[nova grotto]

How do you make another actor jump whille not possesing them

[maiden wadi]

Unless you can collect half of a cat. 😄

[fathom hazel]

no, originally i had it as an int but i read something somewhere and for some reason i decided against it 😭

that was funny though lol

[sand shore]

Hi I’d like 0.463 of a cat please

[fathom hazel]

coming right up!

[sand shore]

“The right way” is generally nebulous, but Auth’s reply is definitely better practice than how you have it set up. I never have my game logic setting text like that.

[fathom hazel]

by best practice i mean not the terribly shitty non functioning code i currently have 🤣

[fathom hazel]

is that setting function also in the gamestate?

as well, should the setter function subtract 1 from the cat, or should i do that in cat actor?

[sand shore]

Cat can call Game State -> Collect Cat, which can then subtract 1 from the cats to collect and can add 1 to the cats collected - using setters

But I’m saying that in a vacuum

[fathom hazel]

where did we get a cats collected variable from haha

oh, is that for the hint system?

[sand shore]

Can’t know your project like I know mine

I forgor

[fathom hazel]

speak of the devil i just found a cat. Hes on my lap

[fathom hazel]

no worries lol

[sand shore]

I say do what makes the most sense to you

[fathom hazel]

collectCat is a function inside gamestate correct?

unless you suggest putting it elsewhere.

[fathom hazel]

whats up with the delegate/event dispatcher as well?

[fathom hazel]

RAHH IM BACK TO THE CASTING OF BP HUD SOMEHOW

i thought i got it, although now im having this error. Blueprint Runtime Error: "Accessed None trying to read property K2Node_DynamicCast_AsC_CGame_State". Node: Bind Event to ED Cats Collected Graph: EventGraph Function: Execute Ubergraph BP HUD Blueprint: BP_HUD

How its setup: Gamestate has a function called collectCat. Collectcat has a event dispatcher called ED_catsCollected. It calls ED_catscollected at the end of the function. In the BP_HUD, i have Event on initalized set into bind event to ed cats collected. I think the issue is with Event on initialized but im not sure.

[frosty heron]

call the jump function of w.e character you want to jump.

[dark drum]

On you're event dispatcher, add an int property and pass the new value through when the dispatcher is called.

On the custom event, also add an int property (so it matches the dispatcher).

Then move the 'Get GameState' -> 'Cast' to the on initialize event so the binding can be created correctly.

You can then correct the 'Custom Event' to use the int that gets passed through to update the text without needing to pull it from the game state.

[storm solar]

Would anybody have any idea on this issue?

[past hull]

hello,
I am having an issue with Damage Event for my Perception AI. If I test my code with the X keyboard shortcut, it works and calls the Damage Sense in my AIC_NPC AI Controller.
But if I call the Damage Event in my Weapon Blueprint, the Damage Sense is never triggered.
When looking at the debug, the damaged actor is correct ( of type BP_Stalker wich is my ennemy type )

I dont know what I am doing wrong

In debug, I shoot on the ennemy, the Damaged actor is the BP_Stalker I shot at. So the damage event should be reported on the AIC_NPC that is implemented right ? Just like when I press X

[dark drum]

It looks like its attempting to initialize gameplay tags but one of the paths is empty. Double check to make sure you don't have any empty/null gameplay tags in your project and then rebuild.

[storm solar]

I looked through them before but couldn't find anything that would cause an issue.

[dark drum]

You have a null 'Gameplay Tag Table List', either set it or remove the entry.

[storm solar]

Ah that was it. thank you, that helps a lot!

[narrow sentinel]

Anyone know what that yellow message is meant to mean ??

not sure if that appearing is a good or bad thing thats all

[sand shore]

well its probably not a GOOD thing but it doesn't have to be a bad thing.

Do you have shadow artifacts? If you do, then you should address the message

[narrow sentinel]

well at the moment I am using a mix of placeholder Geomatry standing in until I finalise a basic level layout so I'm thinking is might be that causing the yellow warning

the geomatry one

[maiden wadi]

It's essentially just telling you that you have too many lights trying to affect a pixel and that you either need to reduce the light count affecting an area or increase that value.

[narrow sentinel]

when I say geomatry I mean them ones

[narrow sentinel]

arrr so it'd be a case of increasing say the attenuation on the lights so less of them cover more area would prob solve that issue

[distant grotto]

why wont physics work on this actor?

i want it to collide and simulate physics with the level but not the player.

[narrow sentinel]

any idea how I would delay the spawning of player character ?? essentially whilst all the sub levels load is I don't want player to be spawned and then when ready I tell game mode to spawn player

[last peak]

Delay node before the spawn 🤷

[narrow sentinel]

so my issue is Game mode has stuff by default to spawn the player I need to delay this so I can manually tell it to spawn player when ready

[last peak]

Spawn a dummy empty pawn then switch to the character once everything is done

[maiden wadi]

GameMode can delay beginning play and spawning default pawns until you set it to.

[last peak]

Ughhhh an Authaer comes instantly and knows a better solution, good that i killed my ego a long while ago 😄

[narrow sentinel]

so your saying I leave default pawn null and manually set it when I want game mode to spawn it ??

[maiden wadi]

No. GameMode has a boolean thing for... Sec I need to open IDE.

bDelayedStart. Set this to true.

And then whenever you're ready you can call StartMatch

[narrow sentinel]

arr okay

[narrow sentinel]

so apparently this isn't something I can set in cpp in my derived game mode

[maiden wadi]

It is. You can even do it in BP. It's in AGameMode, not AGameModeBase for clarity.

[narrow sentinel]

arrr my derived game mode is the latter as I couldn't inherit from GameMode

i've changed that so I'm deriving from AGameMode

whats differce between them both the none base one to the base one

[maiden wadi]

Make sure to change your GameState as well.

[narrow sentinel]

so gamestate is the default one I've not made a derived Cpp yet for that, I prob should though tbf

[maiden wadi]

And the difference is basically just matches. GameMode extends the original to add a "match" like system. You could look at it's implementations for that boolean and do the same thing yourself without the matches.

[narrow sentinel]

arr okay I spose I can still dervive from the gamemode one and jsut not use the match stuff if I don't want to

[maiden wadi]

You don't necessarily need a derived one if you don't have one already. But I would. GameState is useful. But at the very least you'd need to swap it out for the other. The game won't work if you're using GameMode and GameStateBase.

[narrow sentinel]

so i've gone with the following using that bool to delay player spawn and just using the restart player function to then actually spawn the player

and for now this seems to work okay so think i'll call that a win of sorts

[fathom hazel]

i didnt even need to do all that. I could just have set the initalize to first do the cast.

is there a reason you suggest doing the rest of that stuff?

on second look, it appears i overlooked something. Not sure how to differentiate between the cats (unless i duplicate the bp)

[dark drum]

Yes because most of the time if a value has been updated, the things that need to know will need to know the new value. This can save you having to manually pull it from the game state.

Ideally, we wouldn't even do the binding in the widget itself but one step at a time. 🙂

[fathom hazel]

what do you mean by wouldnt even do the binding in the widget? where would we do the binding?

id like to do this right so i dont learn something wrong and have to forget it.

[dark drum]

It can vary. Where do you currently create the widget from?

[fathom hazel]

a hud class thats set to the gamemode.

[dark drum]

You could do the binding there after you've created it. You can use the 'create event' node and connect the created widget and select the function.

This means the widget doesn't even need to know about the game state. (Assuming you do my previous recommendations)

As for why, it can allow widgets to be reused in different places more easily. Especially when you use child widgets.

[fathom hazel]

nevermind 💀 . one step at a time as you said. Let me do the previous things first quickly

[fathom hazel]

how do i set this custom events property to match the call property?

[dark drum]

If you pull from the red square you can create custom event and it'll automatically match.

Alternatively, just add the same properties to the custom event.

[fathom hazel]

got it. Had to recreate the event so it worked.

[dark drum]

Yea, there can be lots of little changes you can make but going through them all at once can be daunting. Things that for smaller projects probably won't make a difference but it can be good to get into good habits. 😅

[fathom hazel]

exactly why im so persistant on doing things the right way, that way i dont learn bad habits

[dark drum]

Just to clarify, there's not many 'wrong' ways, just better ways. Understanding how to do things 10 different ways is great when you start to build your own systems. This allows you to better pick methods that best fit your usecase.

Sometimes I'll use a less optimal way because I can't warrant spending the extra time to do it. 😅

Granted there's been a few occasions where I've regretted it. 😂

[fathom hazel]

yeah, for sure. Glad to get the logic right in my head so im not having a yandere simulator type game 💀

uh oh.

[dark drum]

Refresh the event dispatcher call node.

[fathom hazel]

i didnt even know you could do that wtf

thank you lol

alright, its working. Awesome

now im running into the issue of the fact that i have 3 of them, and when i click one, the rest of them dont work.

its due to this logic here

would the best way to fix this just be duplicating the actor bp every single time?

[dark drum]

No, you shouldn't need to duplicate the class if it functions the same.

[fathom hazel]

what do you suggest then?

How could i fix this problem? i have to differentiate between the cats somehow

[dark drum]

So what's not working exactly?

[fathom hazel]

actually, duplicating the cat actor might be the best course of action for later on. Im looking to impliment a hint system to where a cat meows if you cant find it.

[dark drum]

Is the 'found' variable set to false on the 3 instances placed in the level?

[fathom hazel]

not sure how to check that, but if it helps its the exact same blueprint class placed down 3 times. So i assume after i trigger one, the rest become found because theres no current way to differentiate between the cats.

[dark drum]

Each instance has its own set of variable values that are unique. Changing one won't affect the others when changing at runtime.

Add a print string to the start of the interact and check it runs on all of them.

[fathom hazel]

no, it only writes on one.

[hardy merlin]

Can anyone point me towards tutorials for editing animations within Unreal Engine?

[fathom hazel]

maybe i dragged the mesh instead of the actual actor?

[dark drum]

It could be an issue with the way you handle the interaction itself. How do you trigger the 'interact' event.

[dark drum]

It's possible, select them in the level and make sure they're all the actual blueprint and not just the mesh.

[fathom hazel]

interact interface

[dark drum]

You might be better to ask in #animation I'd imagine the folks that frequent that channel would have some good sources.

[dark drum]

Yea, but how are you calling it.

[fathom hazel]

ahhh

thank you

i have found logic twice which is why i cant interact

alrighty ive got another thing

currently im manually setting how many cats there are. I figured i could use get all actors of calss, and set the actor class to actor cat. From there i could drag out the out actors and use it to set how many cats there are remaining (initally, on event begin)

although i cant drag out actors to cats remaining

is there a conversion im missing?

that way i could just drag cats out and not worry about counting the total cats every time

[last peak]

https://tenor.com/view/the-summoning-bad-cat-hitting-broom-gif-10352523

You can get the length of the array but its useless overhead that you create with get all actors of class, thats dirty

If its really just at the beginning of the game, ok it wont hurt you too much but there are probably still better ways

[dark drum]

If you don't want to use the get all actors of class, you can just add some logic to the cat on begin play that would increase the count by 1.

[last peak]

You have to become the purest coder in existence, you shouldnt even use a engine you should use raw c code ...... or even better a pc with punchcards and raw boolean logic as language !

[dark drum]

Because there's no need to loop through the array, it's probably the most efficient method to be honest.

[last peak]

Isnt get all actors of lcass doing a loop internally trough them all ?

to spit out that array

[last peak]

Meanwhile me putting references in the game instance because im lazy XD

[dark drum]

It used to be in early versions back in UE4 but now it's a hashed map so is actually pretty quick.

The issue tends to be having to loop through them as people might not always understand how many entries it'll provide.

[last peak]

Mhm gotta have to watch the mythbuster vid again

[dark drum]

If you actually need to get all of a given actor it's not a bad option, you just need to be wary of needing to loop through them.

Looping through to find a single instance isn't ideal. I've seen that a few times. 😅

[last peak]

This seems like peak programming to me

[dark drum]

😅 there's a get all actors with tag to mitigate the BP loop. Lol.

[last peak]

https://tenor.com/view/rainn-wilson-shh-secret-prank-gif-17131726

[dark drum]

I guess we can't reveal all the secrets. Lol

I wish actors had a default gameplay tag container.

[maiden wadi]

It's funny. I have yet to ever use the loop with break for anything in the entire time I've used this engine.

[dark drum]

I used it yesterday to find a specific child widget. 😂 (From about 13)

[maiden wadi]

I have a habit of making functions for my getters like that. So they all just return out.

[mystic blade]

very curious as to why the default third person character blueprint was changed so drastically in UE 5.7 and why "EnhancedInputLocalPlayerSubsytem" has been seemingly omitted

was it just for general streamlining?

[dark drum]

Adding the input context mapping was moved to the player controller I believe.

[next hollow]

It could also be seen as a general matching C++, so if you are BP only, you can just add a bool check in that 1 function to prevent all movement for example.
While BP doesn't have access to the C++ function that internally does that.

[mystic blade]

its definitely cleaner than before

[distant grotto]

how do I make this overlay fill the screen?

[mental trellis]

Set the anchor points to the edges of the screen?

I'm sure there's a button that does it for you.

[distant grotto]

they are

i cant drag the anchor points out any further

I think the sizebox is messing with it but its not a child of it so i dont get it

[mental trellis]

You may also need to reset the offsets from the anchors.

Back to 0.

[distant grotto]

they are

i think if you have a sizebox it limits them to the size of the sizebox

becuase if I use a different anchor type i can drag it around freely

why is the umg stuff so hard to work with

[maiden wadi]

It's not.

[distant grotto]

I dunno i cant ever get it to behave

[maiden wadi]

What you have up there won't be affected by that sizebox. The sizebox doesn't wrap it. The only thing that will affect it are your anchors in the canvas slot.

[distant grotto]

this one? I dont see any anchor options for it

[mental trellis]

Select the overlay

[distant grotto]

it seems to be locked to the size of the sizebox even though it isnt a child of it

[mental trellis]

That is the same size as its parent.

(the canvas panel)

[maiden wadi]

Uncheck SizeToContent

[distant grotto]

on the overlay?

the canvas panel doesnt have that checkbox

unchecking it on the overlay didnt change anything

[mental trellis]

Probably because it has no content.

But your anchors are correct. It's that size because its container is that size. If you want to change the size of the overlay, you need to change the size of the canvas panel.

[distant grotto]

how do I do that?

[mental trellis]

Maybe the root item has some preview size setting?

[distant grotto]

copy pasting the widgets into a new blueprint makes it do waht I want

[mental trellis]

Did you check the settings of the root item? Or the preview settings at the top-right of the viewport?

[distant grotto]

nothing seems out of place here

oh if i set it to fill screen the overlay fills the screen, it doesnt in game though

so copy pasting it to a new widget didnt fix it

what Im trying to do is have an overlay that fills the whle screen so I can check if the mouse has clicked off the actual widget

[mental trellis]

And that is the details of what, exactly?

[distant grotto]

The root item

[mental trellis]

Which is?

[distant grotto]

User widget

It's at the top of the hierarchy, above the canvas panel

[mental trellis]

Well, unless you're adding that widget as the root widget in your hierarchy, it will only fill the area it's given.

[distant grotto]

No I mean it's the details panel of wb_slotactions in the message I'm replying to

I guess the root widget is the canvas panel then

[next hollow]

Its goofy to see some BP graphs from stuff you work on. 😛
(not bad of course, just goofy)

[sacred canyon]

maybe I wasnt very clear about this the other day, but how do I rotate the player to point at the cursor, but on its own local axis?

rotates on world z right now, and I cannot figure it out

[next hollow]

Just ignore the bad rotation, seems like the easiest fix.
You don't care about, what is that Roll? So, just 0 out roll.

[faint pasture]

cook up the rotation as if it was not tilted, then combine rotators to tilt it

[sacred canyon]

that is already only rotating on z

Ive tried with local rotation too, does the same thing somehow

the only thing that gives the intended result is "add local rotation", but I dont know how to do the maths for adding instead of setting

[tropic torrent]

bro put a not instead of using the false

[sacred canyon]

oh thats an actual node, I thought you were just saying to do that

still, no idea what to do with it though

[faint pasture]

combine rotators

mess with it

[glass blade]

Can anyone help me with blueprint math? Given a base value of 130, how can I repeatedly subtract 30 so that each subtraction uses the previously calculated result instead of the original 130

[dark drum]

Can you provide more context?

A = A-30?

[maiden wadi]

Exactly as you stated? Can you show the code you're having issues with that is reusing the original 130?

[grand pagoda]

I'm having trouble figuring out how crouch is implemented by default in Unreal BP. Crouch and Uncrouch don't seem to trigger the OnStartCrouch and OnEndCrouch events. Are they supposed to?

[grand pagoda]

Should be fairly simple, start with a variable that holds your original value, then set that variable to it's own value - the amount you want to subtract (in this case 30). Should be something like
Current Value = Current Value - Deduction -> Repeat

[sacred canyon]

yes I had no idea what I was supposed to do with that

but I managed to find a way with add local rotation and minus the difference between current rotation and where it should be

[woeful mesa]

Not sure where to post this, but I think here.
Do you think that this movement system is viable? I made it myself and think it will be easy to change values.
https://docs.google.com/presentation/d/1eZ-U3efKJBMJ4HvnMvbnXCvX7YV4n6nS9TC8diTpXZE/edit?usp=sharing

The end product that I hope to achieve is something like here: https://youtu.be/PHXinBn1pyA

[faint pasture]

Viable for what?

If it's single player anything goes, you can do whatever you want. Multiplayer takes a lot more consideration.

[woeful mesa]

Do you think it would work for multiplayer?

[last peak]

Now for you the words of every wise developer

https://tenor.com/view/farotech-it-depends-gif-26516110

[woeful mesa]

Ok ok. On what exactly?

How it's executed?

[crimson briar]

The movement in MP is a little more complicated. From my limited knowledge with the CMC the client executes movement, saves some data in batches and sends it to the server for confirmation. If the server movement matches, everything is ok. If not, there is lag or rollbacks. It also does some smoothing and automatic replication of course.
So it depends if you took it into consideration when making your own movement system.

[timber wind]

What are you worried about? Lag? You can simulate network lag through the editor

[fading raptor]

Hello everyone, I've got a problem : I'm trying to make a "Press E to interact" widget show up and disappear when entering/exiting a box collision for a door. The thing is that it works for the exiting part but not the entering one. If it helps, collisions of the FP character are Query & Physics & the collision box of the door is Query Only

Thanks in advance !

[timber wind]

Begin Overlap (Widget) and EndOverlap (BoxCollision), is it intended?

[faint pasture]

Maybe, but if you have to ask...

It'll be hard

Anything is technically possible

[fading raptor]

I didn't see it I must have done it too fast, thanks !

[woeful mesa]

Not just lag. Mostly if it's going to work. As in whether it's possible for other players will see the movement or not, because I had an old movement system and when playing 2 editors the movement didn't rotate on the other player

[woeful mesa]

Ok ok, I'll try to

Thanks

[faint pasture]

Actually on 2nd look here I see nothing going on that can't be done by Character with a bit of extra code

It's basically the exact same as any other character system where you can see the character aim in yaw and pitch

[spare tinsel]

would it be correct that inside an actor i get objects (in the entire level and outside the blueprint actor) with a tag and do this? cause in any case targets are expecting a scene component and a primitive component

[faint pasture]

you can hide actors

[spare tinsel]

in real time? its just that I want to hide (and disable it case they have some functionality), constantly in case of gameplay circumstances

[mental bobcat]

when I show (set visibility, enable tick,) of the ui, I get this weird artifacts. Does anybody know whats the problem here?

[next hollow]

Assuming you mean the goofy grey cube.
You can see, its cuz the shader has to compile.
Are you running a packaged build, cuz a packaged game compiling shaders seems odd.

[mental bobcat]

Thank you for the reply. Its a stand alone mode.

[next hollow]

Thats why then.
For the best results use a packaged build, or just the normal play in editor.
I know the explicit standalone has its own shader caching, so it has to compile more, thus more artifacts like you appear to be seeing.

[mental bobcat]

Thanks. let me give it a try in a packaged build

[drowsy jungle]

Noob here.. How to send variables to a different blueprint !?

I am building a counter that counts the amount of people I save reaching them to a certain area !

So the collision counter is between a follower blueprint and a trigger box. I have the functions done but how do I send these functions/variables to my first person HUD ?

[mental bobcat]

casting is one method but not recommended. Storing the variables in a gameinstance or gamemode and bringing them might be an option.

[drowsy jungle]

How do I do that ?

[mental bobcat]

use get game instance or get gamemode node and cast it and get the variables.

[harsh nebula]

Blueprint interfaces is another widely used method.

[drowsy jungle]

You mean I can use that to globalize any variable ?

[harsh nebula]

You could.

I'd recommend looking for some HUD tutorials on youtube, most will give you the info you need to update the HUD. Then you just change the variables for your own etc.

[sturdy arch]

Im trying to make a 4 montage attack combo. It worked fine until my roll or hit react montages interrupts this, making me unable to attack as the variable will still be set to true. I tried to fix this by making the variable false when interrupted and resetting the count, but now when I spam left click, the interrupted is triggered and im stuck spamming the first attack. I can still do the combo but only after the notify is triggered, but I want to make it so I can spam left click while having it ignored as a interrupted. Any help is appreciated

[crimson briar]

If the montages can be interrupted, relying on delays and notifies goes out the window since they won't be reliable anymore.
One "not so great" fix when the montages can be interrupted would be to reset every other state before starting a new montage.

And why is it breaking when spamming - I'm not sure, hard to ready anything on the screenshot

Hmmm, but you have the bool blocking entering into these montages so an attack shouldn't be able to interrupt another attack.

[frozen hedge]

Just a question, might just be me but why is the attack float set at the end after delay?

Does that originate back to the normal combat anim

[merry sparrow]

hey guys any one have idea of handling the loading screen for unloading a level full of actors and assets and load another level with a lot of actors in it !
i made it this way i put an empty level between these 2 levels to handle this loading process to be able to at least play the loading animation on the widget ! problem i am facing is the loading screen even freezing for short amount of time and i dont like this at all i need to make it way smoother

[hearty rain]

Are you using level streaming ?

Spawning actors is done on the game thread so it will be synchronous, hitches are unavoidable unless you spread the spawning over time

[dark drum]

Starting another montage on the same montage slot will interrupt any other montage playing on it.

I can only assume that your roll and hit reactions are also montages which is why it interrupts the attacks.

[crimson briar]

I just noticed he is setting the attack bool to 0 on both interrupted and notify, so yeah, if the notify is not at the end, it will be possible to interrupt with another attack

I would move changing the bool from the interrupted of the attack montage to the start of the other montages that can interrupt it. It is not a great solution but it shouldn't bug out at least.

[dark drum]

Triggering montages can get complex. A hit reaction for example probably should interrupt an attack montage (and stop the combo), but doing a roll shouldn't be allowed during an attack.

It would look at using a gameplay tag container that could be used to help distinguish the state to determine if a montage can be played.

[barren tangle]

Hey do i wrongly use the Disable Input node?

inputs are still working

[dusk shale]

Hi, Im new to unreal and am having issues calling events/functions between BPs. I have this event in SLAMMesh Blueprint (img 1) which I am trying to call in OSCServer (img 2) but am not seeing it appear. am unsure of the correct approach, as few online options tell me to use functions but that also doesn't seem to resolve the issue

[crimson briar]

What is the note under the Event definition?

Ah I see, you marked it with pass by reference. But it doesn't work like that with custom events. I wonder if this is also blocking the call to the event, I'm not sure though

Huh wait, but it is the default behavior with arrays. Hm, I'm stumped, that's new

[hearty rain]

Seems correct, try to unconnect the "player controller" input, it will desactivate every controllers

[merry sparrow]

no i am not using level streaming so i have to use spawn over time ,interesting its like puting half actors spawn at the start the other half could be load while game is running !

[hearty rain]

Yes with some kind of spawning queue, with prioritization, you can get something smoother

[merry sparrow]

good point thanks !

[barren tangle]

even like that every controller continue to works... 😄

[narrow pulsar]

Why isnt the gameplay cue playing the montage? And any prints i put inside print nothing either

[hearty rain]

Where are your print ?

[narrow pulsar]

I removed them because they werent printing

[hearty rain]

stupid question but have you got a slot to play the montage in your anim blueprint ?

[narrow pulsar]

yes upper body

if i give the montage to an ability it works but yea

[hearty rain]

Ok ! Well I can't really help right now, but any reason why you play that in a gameplay cue ?

not sure it's the safest place to do it

[narrow pulsar]

No particular reason, I wanted to play a sound as well in the impact location so thought might aswell do both montage + sound in a gameplay cue (also because never used them before so wanted to learn about them)

[hearty rain]

I may be mistaken but Cues are more to play sounds or vfx, but not montage. For hit reactions I did it in a gameplay ability

but well, I won't commit to this

[narrow pulsar]

well

I did notice that I can only make the animation play if i validate it as the server

kinda wantd to play the animation locally as well

[barren tangle]

Any idea why it doesn't work ?

[next hollow]

You didn’t pass in a controller.
Just looks like you got it confused, like a ton of people do.

[barren tangle]

if i put the game mode ui only, i cheat in a way

but before to call my function i set the mode to

so why the disable doesn't work... 😒

[next hollow]

Because you didn’t pass in a “controller” for the input.

Just a target

[barren tangle]

yes i did juste before, we told me to remove the controller to disable all controller, but resulat was the same

[barren tangle]

i have also tested with get Player Character

and i'm sure that pawn and character are valid

i check that as well

[next hollow]

Ok, so then let’s reset. Lol
Cuz idk any context around this.
Your trying to disable all player input, and it’s just not disabling?
Even with the controller connected.

[barren tangle]

exactly

but when i call the fonction : Set Ignore Move Input
from the controller, it block the move input, issue is i have also button input.. so i can't use that

that block the movement input but not all other input so that doesn't help

[next hollow]

Then what would disabling all input get you?
Then the button still wouldn’t work anyway.

[barren tangle]

don't understand, can you rephrase?

[next hollow]

Oh, I miss-understood.
I thought you said that ignore movement, also disabled your button.
It’s that your button still works.

Get the “controlled pawn” from the player controller.
Getting the 0 pawn, could be pulling a different one, if multiple exist.

[barren tangle]

i tryied also the get controlled pawn from the player controller

same result

is it because of the new enhance input system?

[last peak]

You can override inputs in your uis

[barren tangle]

does't the disable input work with the new enhance input system?

[next hollow]

I’m actually not sure.
It may not. Lol
But, the it’s easy anyway.
Just remove the input context.

[barren tangle]

how do your remove the input context?

[next hollow]

Should legit be “remove mapping context”, from the enhanced input component, same way as added.

[barren tangle]

it works but it looks like cheat 😄

because i feel like the disable input doesn't work in fact...

[next hollow]

I would’ve assumed it still worked, cuz the input still has to like “go somewhere”
It doesn’t just go to every actor in the world.

[barren tangle]

i will create a global fonction that will find all player controller, and enable and disable the mapping context for all of them. and i will call that fonction from there it will be better

it works, i will assume the node doesn't work with mapping context

[white parrot]

Same way you added it

[dark drum]

I'm curious, were have you setup the input action events? In the character?

[barren tangle]

Into the controller itself

I don’t put anything inside the character

Controller call function in the character but all input are managed by the controller

[dark drum]

Ahh, that's probably why the disabled input wasn't working.

You'd have to disable input using the controller as the target and source I believe .

[narrow sentinel]

so am I not thinking right but do Actors not have a cull distance ??

[maiden wadi]

https://tenor.com/view/wtf-huh-what-the-f-why-wtaf-gif-5589464956156088627

[maiden wadi]

I don't think so. It wouldn't make sense for them to. Culling is a rendering thing. So it'd be on the primitives inside of the actors. Actors themselves have nothing to do with primitives except that they can hold a collection of them.

[narrow sentinel]

so I've checked and the point light doesn't seem to have cull distance on it either

I spose I can put in my own thing where theres a sphere and when player overlaps with it I do the optimising stuff maybe

[barren tangle]

That would make sens I will try at home

[barren tangle]

Character doesn’t have to know the input 🙂

[narrow sentinel]

wait i'm looking for wrong thing

I want draw distance not Cull distance

[maiden wadi]

Yes it does. You just said you're calling inputs in it through the PlayerController. You're just adding indirection by not allowing the character to handle it's own inputs. And you're forcing the Controller to have an extra job it doesn't need.

[barren tangle]

Controller manage the input not the function of the input

[maiden wadi]

What do you do when you add a boat to your game? More inputs in the Controller?

How about a plane? A new set of inputs?

Are you just going to switch on pawn type to delegate these out?

You're adding unnecessary complexity.

[hearty rain]

Sounds like it's going in the wrong order from an architectural pov

[whole citrus]

Can someone help me turn my blueprints into c++? I really don’t know how but my deadline is in 3 days

[hearty rain]

It's really not that simple, but why do you need to convert to c++ ?

[whole citrus]

Making a school project and the person helping me made logic in blueprints

I now need to convert that into c++

I don’t have to use the c++

I just need the c++ equivalent

[whole citrus]

Alr

[white parrot]

That's not really the equivalent, since you're not creating the widget(?)

if(WidgetInstance = CreateWidget<CharacterGUI>(GetWorld(),WidgetTemplate)) WidgetInstance->AddToViewport();

[tired blaze]

Hey guys and good morning! If anybody would help me out here, I would really appreciate it. I am making a widget that allows you to select your voice output and input devices. I am struggling how to "store" two strings at once while using a combo box. I don't wanna use the ID to display the device itself in the combo box (as seen in the fourth screenshot). Since the selected item is the string that shows the display name, I can't use it to change the device itself. I can only use the ID to change the device itself as seen in the second screenshot. How can I have it where I select the Display Name in the combo box while having the ID stored somewhere when selected?

[whole citrus]

Oh okay tysm

[narrow sentinel]

so I have an issue where on game instance I create a loading screen widget when transitioning between Main Menu and Level but because the create widget required a owningobject and at the moment I'm passing in the current world when the main menu world unloads and main level loads the loading screen widget is destroyed in process

question is there any way to get around that or would I just have to recreate the loading screen widget on main level being loaded ??

[dusk shale]

Hi could someone please help me with this issue. have tried a few options but still quite lost

[maiden wadi]

Don't use the SelectedItem.

For a start save those arrays from the GetAllEOS things.

Get your ComboBox and pull SelectedIndex from it and use that to get the index from your cached array of that type and pull it's ID

Then you can feed the DisplayName to the Combo Box's options.

[barren tangle]

No the boat have the function he needs for the input he needs. The controller doesn’t need to know which fonction to call, he juste provide the data to the concerned classe and the other will manage the input provided

[maiden wadi]

Do you read C++ by chance?

[barren tangle]

i can read c++, why?

[barren tangle]

It was that indeed !!

[maiden wadi]

If you check out APlayerController::ProcessPlayerInput. You can see how the controller already delegates input to other classes when you place input in them. Like the Pawn or anything else.

It runs APlayerController::BuildInputStack which builds a list of UInputComponents to process in that order. The last thing added is the first thing process. So the order of preferred processing is anything that has been explicitly had EnableInput on it. Then the Controller itself. Then the Level Blueprints, and then the Pawn you currently possess.

This is all native and done already. Your PlayerController is already doing this. And you're narrowing all of that down into just the Controller and negating all of this structure that has already been done for you generically.

[dark drum]

That's kinda the point of the input actions though. That is the function/event.

It means you can have different characters that use the same input action but handle it differently.

The controller is more for logic that all characters would have. The thing that pops into my head is for thing like opening a pause menu. It doesn't matter what you're controlling, it should function the same.

[maiden wadi]

Technicality. But I'd argue this too. "The controller is more for logic that all characters would have."

It should be for input REGARDLESS of whether you have a pawn possessed or not.

If all characters can have it, then it should live in their parent class.

[barren tangle]

yes, the controller doesn't needs to know what he his controlling

it's inside the controller, you said that the left part is done directly by the character

[tired blaze]

Thanks for responding, I appreciate it. But how do I save those arrays in the first place? A variable?

[barren tangle]

so we can avoid all the right part

[narrow sentinel]

hmm so seems issue is when the Main Level is loaded the player is spawned delayed and it seems this remove loading screen widget from screen which I don't want

[dark drum]

Yea, this is probably a better way to word it.

[maiden wadi]

Correct. Just right click on them both and PromoteToVariable and hook it up.

[surreal wagon]

Does anyone know why I don't have any root shake patterns?

[dark drum]

That BPI is just adding an unnecessary middle man. Just add the IA_Move to the character.

[surreal wagon]

Am I supposed to create them on bp¿?

[barren tangle]

Yes but when you build an UI controlled by the controller

if you want your UI to be controlled as well by the controller

you have to code that inside the controller

[dark drum]

Yes there's a class you can create a child of for it. If you search shake when you go to create a new blueprint it should pop up.

[dark drum]

I'm still not sure what you mean.

[barren tangle]

for example

i press pause menu. How do you controlle the menu with the controller?

you also put the event into the Widget?

i did that last year so i don't remember everything but i think it didn't work

[dark drum]

UI uses a different input system. If you set the input mode to UI only input actions don't even fire.

Widgets has its own nav system where it traverses the focus tree. (Granted theres more to it than that) You can also setup nav rules for what widgets it should navigate to when you press the various directions.

Widgets also need to be focusable and hit testable and it works out the box. (sort of)

[maiden wadi]

CommonUI actions. ❤️

[dark drum]

I still don't understand how that works. 😅

[maiden wadi]

Like in Atre. Our pause menus have nothing to do with PlayerController. The HUD widget itself listens for escape as a CommonUI action and puts it up. Then the escape menu itself listens for escape as a dismiss key like all other menus do. None of it from the adding of the widget or the dismissal is PlayerController routed.

[white parrot]

You have CommonUI for that, it doesn't even use a controller (on the high level atleast)

[maiden wadi]

I'd check Lyra for their implementation. But you can do this with invisible zero size CommonButtonBase buttons in that menu too. Set a TriggeringInputAction or whatever it is on the button and it'll run it's OnClick which you can do stuff off of.

[dark drum]

I assume that's the back handler thing?

[maiden wadi]

For the dismissal, yeah.

[white parrot]

Don't you just bind input actions manually when the menu pops up? Instead of having a controller and IMC

[maiden wadi]

CommonUI input actions, yeah. Not UInputAction Input Actions.

[barren tangle]

I tryied multiple time CommonUI and it was not working as good as espected.
So to be able to easily manage screen without CommonUI the things was to put the management into the Controller

[white parrot]

Yes, FUIInputAction (IIRC).

[white parrot]

It's a learning curve above simple UMG's, worth it though.

[surreal wagon]

would you kindly tell me which one it is?

[tired blaze]

Hey, Thank you! It worked for me. I was able to get it working after thinking for a bit how to pull the index from the get selected index.

[dark drum]

Oh my bad, I was thinking of the camera shake base. 😅

What you need is the 'UCameraShakePattern' class. You should have 4 by default though.

It doesn't look like it's exposed to BP.

[dark drum]

Is this something you have to do in C++ or is it exposed to BP?

[white parrot]

I'm almost positive it's C++ only, i was mistaken though. It's FUIActionBinding.
However, it's just one class you have to make with 2 functions for add and remove (in order to make it usable in blueprints).

[dark drum]

Maybe its one of the pieces I've been missing. I've not done much with commonUI from the C++ side of things.

[white parrot]

What are you struggling with?

[maiden wadi]

@white parrot@dark drum This is what I meant by the invisible 0 size button. You can use them to fake triggering actions in BP only without doing manual C++ binds.

[narrow sentinel]

anyone able to help at all, I'm trying to have a loading screen widget be peristent across level transitions at the moment main menu into main level. issue at moment is when the main level loads and the game mode calls the temp pawn to be spawned it's removing the loading screen widget before I've had chance to manually call for it to be removed

[dark drum]

Just wrapping my head around the whole input actions in commonUI in general. I can never seem to actually get anything to work.

[dark drum]

It's not something you can do in BP only land as far as im aware.

[white parrot]

I guess that's one way for a Designer/BP-Purist, didn't really take a look at how Lyra does it in-game yet. Also I'm trying to avoid BP's like the plague.

[narrow sentinel]

so my loading screen widget is a cpp class and its being created and removed on Cpp side

[narrow sentinel]

I'll ask in cpp

[white parrot]

IIRC, you could use a manager, which is a GameInstanceSubsystem (which is kept alive during level streaming) and would control the widget.

[dark drum]

If I was to take a guess it's most likely because the player controller that owns the widget gets destroyed (during the transition) which means the widget would get removed as well.

[dark drum]

I never thought about creating a widget with the GI as it's owner. I might have to give it a test.

Edit: Owner requires a player controller. 😅

[narrow sentinel]

so it's the game mode causing it cause when it creates spectator pawn it's clearing all widgets from what I can tell

even is widget owner is the game instance

[narrow sentinel]

arr so even though it's not moaning about the GI being put in as owner it's not gonna accept it

[white parrot]

I think Lyra has a decent example of adding those.. trying to recall where

[white parrot]

Pretty sure the owner can be GameInstance

[narrow sentinel]

issue is though how would I keep it from being destroyed. Only idea I can think of is I get GM to call GI to create the widget

[white parrot]

@dark drum

static_assert(TIsDerivedFrom<TPointedToType<OwnerType>, UWidget>::IsDerived
        || TIsDerivedFrom<TPointedToType<OwnerType>, UWidgetTree>::IsDerived
        || TIsDerivedFrom<TPointedToType<OwnerType>, APlayerController>::IsDerived
        || TIsDerivedFrom<TPointedToType<OwnerType>, UGameInstance>::IsDerived
        || TIsDerivedFrom<TPointedToType<OwnerType>, UWorld>::IsDerived, "The given OwningObject is not of a supported type for use with CreateWidget.");

[narrow sentinel]

might have found the solution on google and it might stem from the function AddToViewport Function

hmm no still having the issue, i really think issue here is the GM is removing all widgets or something like that

[dark drum]

Yea, I was having a poke around myself. The create widget BP node only has a player controller input and if one isn't provided it tries to get the implied player controller so i'm not sure there's a way from BP.

Although Ryan has states its defined in C++ so a none issue.

[narrow sentinel]

let me query in cpp channel as its starting to feel like it's a thing that can only happen with cpp stuff

[surreal peak]

Using the PC will get your the GameInstance anyway afaik

[past hull]

hello, I have an issue with my conde handling damage.
My NPC is supposed to chase the player when he receive damages. It work when I press W ( for debug purpose ) but not when I fire with my weapon. The generated event are the same.

when I fire with the weapon, the code goes to onFail on the AI Move to . I checked the Pawn and Target Actor and they are correct

[narrow sentinel]

so i've done a callstack thing on cpp to see if it's points to anything useful, the attached file is what I got

i found the issue

I forgot I put that on my game mode ages ago and well it turns out it was being called all along

[timber wind]

I know many people use the Async Loading Screen plugin for this. Do you mean you managed to make a level transition loading screen in blueprint? Does it also animate without stalling while levels load in background?

[narrow sentinel]

yeah it's working how it should now

it was all down to the face my GM was running a 5 second delay on begin play and then calling the loading screen remove function. I forgot I added this so weren't until dumping stack I can see the load screen unload function was being called by GM

[maiden wadi]

Usually. Under normal circumstances.

Widgets can be owned by the GameInstance or a World.

90% of cases a widget will be owned by GameInstance. ONLY the cases where you pass it an invalid controller or a non local player, or a world where there is no GameInstance(editor utilities), will it be owned by a world.

[maiden wadi]

This has nothing to do with the owner.

There's an override in...

[narrow sentinel]

it's fine I managed to sort the issue

it was me forgotting the function to remove loading screen was being called elsewhere

[maiden wadi]

Still. If you haven't I would make sure to add it to the viewport client directly. Using AddToViewport or other UUserWidget calls makes it managed by the subsystem.

This is from the CommonLoadingScreen plugin as a small example.

// Create the loading screen widget
TSubclassOf<UUserWidget> LoadingScreenWidgetClass = Settings->LoadingScreenWidget.TryLoadClass<UUserWidget>();
if (UUserWidget* UserWidget = UUserWidget::CreateWidgetInstance(*LocalGameInstance, LoadingScreenWidgetClass, NAME_None))
{
    LoadingScreenWidget = UserWidget->TakeWidget();
}

// Add to the viewport at a high ZOrder to make sure it is on top of most things
UGameViewportClient* GameViewportClient = LocalGameInstance->GetGameViewportClient();
GameViewportClient->AddViewportWidgetContent(LoadingScreenWidget.ToSharedRef(), Settings->LoadingScreenZOrder);```

[narrow sentinel]

yeah I changed stuff to use the one above after I did some googling and thought that was causing my issue and turned out it weren't i've left it in though cause it don't do anything bad so

[maiden wadi]

This plugin is actually not the answer to that. It can also cause crashes on some systems because it uses the movieplayer.

The real answer to this is to learn to initialize your gameplay smoother over more frames and not hitch your gramethread.

[glass blade]

How would you guys delay a function by 0.1? I cannot use delay inside functions and set timer even does not allow input / output to be passed

i mean i could save the result to a variable and use that but eh thats not the cleanest

its currently in my event graph which work fine but just wondering if theres a way thats more tidy

[mental trellis]

As long as you're only calling it once and you don't expect it to be re-entered, you can add an event to the main graph and have the function trigger that event. That event has a delay which then triggers another function after the delay.

It's a bit meh, but workable.

[glass blade]

Ty, that sounds very clean actually

Also just on a side note. why don't functions allow delay inside them

even abilities allow delay nodes

[mental trellis]

I can't remember if I ever actually tried this btw.

I hope it works!

Might be because it doesn't want to save the scope of the function. All the local vars and such. On a potentially "infinite" amount of function calls.

[last peak]

They are synchronous, have to return instantly

[cobalt plover]

Strange question, but has anybody experienced a large frame drop (120+ normal, 80-90 with drop) if they hold down their left gamepad joystick when pressing play for PIE? When I trace, I see an extra 4 ms taken by a GameThreadWaitForTask, which only shows connections back to FDeferredShadingSceneRenderer_InitViews.

My joystick has a pretty bad deadzone so it was happening without me realizing it. I've found if I stop, reset the joystick, and play again, my frames go back to normal. I can't correct it in PIE though, once it's started it doesn't seem to recover until I exit PIE.

Huh, if I detach/reattach from the player I can trigger it as well.

I'm guessing that the view is still being moved in the editor (even though that window is replaced by PIE), which is slowing everything down.

[wheat citrus]

For components on the same actor is it generally considered better to communicate by interfaces or by references if necessary with casting? Or is it still a case by case basis? As far as I'm aware since they are on the same actor they are loaded into memory with it so the casting memory penalty does not apply but interfaces might still be more modular, maintainable, and I#m not sure which is more perfromant.

[dark drum]

An interface is for when you have different classes that don't share a common parent but need to have/implement the same set of functions.

[wheat citrus]

I see. One thing that I was considering was that using interfaces seems to be more maintainable/modular. In the example below using the interface the actor can have any number of movement dependent components (could even get them by just getting all actor components if that is cheaper since message can silently fail) and removing or replacing one wont break anything while with the references if you remove one component the code breaks and when you add/replace them you also need to update the code manually. But I'm assuming the reference example is still common practice due to it being more performant?

[last peak]

Use components

[wheat citrus]

these are components

[dark drum]

From experience over using interfaces will turn your project into a mess. Making changes can become a nightmare, sometimes making it difficult to find bugs.

You need to lean more into hierarchy and have a base class for your movement component. This would have the core functionality that all movement components should have.

Just to add, you can still use the 'Get Component By Class' from the owner to get a specific component.

Also in your interface example, the interface is pointless as the node you use to get all the components already returns it as that specific class type. That class should have a function that all children can override.

[last peak]

Use them instaed of casts and interfaces

[dark drum]

If something depends on something else, it 'should' have the dependency. Trying to mask it will come back to bite you eventually.

[last peak]

Or proper hirarchy i guess, but these whole inheritance isnt all that great anyways

[dark drum]

Inheritance is great. You can't build a scalable system without.

[last peak]

The unreal engine version of that atleast in bp are components

[wheat citrus]

I dont understand what you mean by "Using them". How do you "use them" if one is depenndent on another without communicating between the two?

[last peak]

Get owner - get component by class - select new component

[wheat citrus]

i see, though wouldnt that just internally cast to the component then anyways?

[last peak]

Yes but casting to the component is fine

they are not heavy

Casting to a actor is aslo perfectly fine btw

So proper inheritance can be used for that too like pattym said

If you make a really lightweight base class with a few important buttons and only cast to that - thats perfectly valid

but the cast like you have it in your picture is kinda problematic

You are casting to a specific class of something down the chain, usually that has funny stuff attached to it like animation vfx and whatnot

[wheat citrus]

so a lightweight base class for the actor that would always have those componets?

[last peak]

If the thing your casting to is very light the cast isnt too bad

just try to decouple what you can

[wheat citrus]

Cause the movement component in the actual project is provided by a plugin that handles movement replication and predictionn so I cannot really modify it but it has some events that need to call other components evennts like that of the shooting component.

[dark drum]

I tend to use an actor component and custom uobject combo.

The actor component manages custom uobjects which I normally create a base class for and then create children from. This would have the core functions that the actor component would call.

[dark drum]

The interface on the movement component makes no sense to me. Unless you plan to implement it on multiple classes it's just sticking a middle man in between the function call.

Considering you can't change it, the first option where you just get the actor component would be the better option.

[wheat citrus]

So if I understand correctly you'd have a single actor component let's call it "SystemsManager" and then some UObject that has some basic implementation of what a System needs to do from which you would inherit more UObjects that then implement each system like Movement/Shooting/Abilities etc? Or am I getting it wrong?

[dark drum]

I was just speaking generally. Id need to know more about what these 3 things are to know if it would be a good fit.

If it's like an abilities system then yea, it might fit. It's pretty much how GAS works.

[wheat citrus]

Alright, thanks for the advice!! I definitely see the unneeded middleman aspect. I was mainly considering since it would allow you compeltely swap out say the shooting compoent for one that works differently and still function while the references would break if you did that but I see now that inheritance is the better way to go about it by having a base shooting class that you call to and then creating a new child if you want different logic

[dark drum]

As another example, 'DialougeManager' would be a component, then it would manage a custom uobject 'Dialogue'. You can then easily change the dialogue how you like by just creating a new child of the dialogue class.

I've done an interaction system where the component had a 'focus response' object that I can swap out to change whether it should do an outline or change the material etc... and then an 'interaction event' object. The main interaction system comp knows about these base classes and manages them by calling the core functions.

[wheat citrus]

makes sense, thanks for the detailed explanation!

[barren tangle]

Hey is there a node to do that but with custom enumeration?

[dark drum]

It's just called 'select' and has wildcard pins.

[barren tangle]

ha but not based on the boolean

[dark drum]

It can be.

[barren tangle]

yes?

[dark drum]

Yea, you should be able to connect the enum to the selector pin and it'll automatically create an option for each enum entry.

[barren tangle]

thanks

[barren tangle]

that's cool 😄

[flat coral]

Hey wait, why can't I override GetOwner in an ActorComponent?

[next hollow]

Because you can’t?
You can’t override everything in BP

[flat coral]

That means there's a way to set variables as Final, how do I do that?

[next hollow]

More info?
Set as final?

[flat coral]

In C++ and other languages, final is a keyword that means an entity cannot be subclassed

sealed in C# I think?

They made a language that was supposed to split the diff between C++ and Java, and then ignored both and made a new keyword lol

[next hollow]

I believe you’re thinking of “private”?

Doesn’t let child’s overwrite it IIRC

But honestly never done that in my BO.
So BP may simply not have access to to do.

[flat coral]

Wait what. That's not what private means at all but the tooltip agrees with you!?

"Private" is supposed to mean that the variable isn't visible outside the class

[next hollow]

Pretty sure it’s offset by 1
Private is locked to that class.
Protected is child’s can mess with.
Public is everything can mess with?

[flat coral]

final is supposed to be "Subclasses can see it, but not override it" where private is "subclasses can't even see it"

[next hollow]

Oh, ok.
Then, yeah.
I don't think BP supports that in anyway from my understanding.

Its either read only, write only, or both, or neither.

From a quick lookup C++ does support that.
But, given BP is an extensions of C++, it doesn't seem like it would be of much help, if you can't ever actually change it in BP to begin with.

Since, C++, and BP specifiers are unique.
C++ final doesn't stop BP, and BP's version of "final" doesn't stop C++

[flat coral]

True but SOMETHING is putting that final in a BP class such that I can CALL "GetOwner" but can't subclass it.

[next hollow]

Thats a BP specific specifier.
Preventing implementation (thus can't override), and only being marked as callable

Looks like C++ is the same, but not with the final keyword.
Its just not marked as virtual

I also think overriding it, would confuse the hell out of the engine.
Since, code owner, and function ower would differ, and probably have a stroke.

[ashen verge]

can somebody help me

im new to game dev and idk how to code an ai that chases you while music is playing

i dont wanna do patroling because im gonna use my ai for chase sequences and stuff

[hollow plover]

Hey all, looking for some advice or help. I'm new to using Blueprints and am having issues accessing a variable from a component tied to a character from within my widget blueprint. I added a screenshot of current implementation, this works just fine when I hard code a variable (Num Slots) and attach my Event Pre Construct to that and then to the loop but this new way doesn't work as expected. Any thoughts?

[slim lotus]

Hey, does anyone know how to set up a Combobox(string) to Anti-Aliasing? Ive tried currently for 2 days straight and cant seem to get it to work. i can either get it to be off or on, but i haven't managed to set up a sequence where you can toggle between AA methods and have it work.

[faint pasture]

Execution is stopping at that first cast

Also you don't need the first cast anyway.

Get owning player returns a playercontroller, you can just get pawn from it.

[hollow plover]

so basically you're saying do something more like this?

[hollow plover]

Alright for those that care, I found a different solution. Instead of messing with blueprints I made a new base widget class for my Inventory system and just created a BlueprintImplementableEvent that takes the variable I needed and is called in my Player Controller class when inventory is toggled. So I'm left with this in my blueprints instead now. Feel free to tell me this is good or bad , always learning.

[maiden wadi]

Not fully following the question. Are you changing the engine's AA settings using a combobox or are you trying to add AA to the text in the combobox?

[last peak]

I think its best to either let the player controller or a own Ui manager component handle control over ui's

What you should not do however is put any code into widgets that is not directly needed to display or control anything in the widget

[slim lotus]

The combobox contains 4 buttons, one is Off, the other 3 are the types of Anti-Aliasing methods such as TAA. By clicking one of them it changes the method that the engine uses, if you select Off then the jaggies come back, if you select TSR the jaggies go away. I can get the combobox to show the list and I can select them and press apply with my settings apply button, but it doesn’t work because the blueprint sequence isn’t correct as I can’t figure it out.

[maiden wadi]

Can you show what your current logic is atm?

[timber wind]

How is it possible to open a level over more frames? I thought we just had the "open level" node and not much more control over that

[dark drum]

As far as I'm aware opening the level isn't async. (hence why the game stalls if its a big level) However, you can change how you load its contents via level streaming, level partition, etc...

The idea is you keep the core level as small as possible so it loads very quickly and then let the other stuff do its thing. Depending on which above techniques you're using, one thing I've seen is using different maps/levels like layers that get level streamed in, leaving the core map pretty empty. They have the main stuff like terrain, large buildings and big features load first and then stream smaller stuff in.

Adding to this, you can frame slice your own logic, so if you need to spawn 1000 actors as soon as the level loads, do 100 over 10 frames instead. (arbitrary numbers)

Just because the level has loaded, it doesn't mean everything is done. You'd be surprised with what you can hide with a half a second fade from black. 😅

[last peak]

So much in gamedev is just smoke and mirrors haha

Ohhh what a cool cinematic fade in effect when you start the game - in reallity you need a bit to load all the stuff

[hearty rain]

Or these sequences where running is disabled while your character is walking and talking in a long corridor

[crimson briar]

Don't forget about tight spaces you need to slowly squeeze through. They carry AAA level loading all by themselves

[narrow sentinel]

out of interest if I have a static mesh inside of an actor and I disable tick of said actor, will that mess with the optimisation stuff the UE will do ??

or will that all still happen and would it purly just be stuff I put into the actor on tick event won't fire

[faint pasture]

Why would anything else be running on tick besides your own code?

[narrow sentinel]

The code from the actor class

Essentially just wanna make sure all the optimisaion stuff still happens even with tick disabled on the derived actor object

[faint pasture]

What optimization stuff?

Does the parent class have code it runs on tick? Or is it just an empty Actor

[narrow sentinel]

Like actor not being rendered when player cant see it and being out of range of it etc

[narrow sentinel]

So essenitally i have a master wall derived actor

Which is empty and then i have my various wall meshes in a derived master wall actor etc

On master wall actor i have tick disabled

And just wanted to check by doing so it wont mess with the stuff UE put in place like actors not being rendered etc when not in view and player not in range of them etc

I assume its only local tick that would be affected by disabling tick on the actor

[next hollow]

Pretty sure, just none of that stuff is handled on the tick you can mess with.
There in different render ticks, and networking ticks sorta shit

[next crystal]

can someone give me 5 beginner projects to make over the course of 1 month

[glass blade]

guys how do you" clean" an array? Say we got an array that returns

1, Invalid value
2, Invalid value
3, valid value -> this is what we want to use
4, Invalid value

The completed pin in a for each loops fires all times even if we have a valid value

[last peak]

the completed pin fires once youve looked trough the entire array

[rose crest]

Copy correct values into temporary array and set old=Temp

[white parrot]

If you know what you're looking for.. use a break?

[glass blade]

No, since the first item is invalid it jumps ot the completed pin straight up

[rose crest]

What do you mean by invalid value?

[glass blade]

a value that is not valid

[last peak]

https://tenor.com/view/duh-sarcastic-whatever-gif-874996418923210673

^^

[rose crest]

Just make proper logic to check validity in loop body

[fathom hazel]

What do you mean increase it by one?

[glass blade]

https://tenor.com/view/why-didnt-i-think-of-that-donald-kimball-missed-that-gif-14910726

[white parrot]

For each loop with break -> array element -> isValid(value you want) -> break?

[rose crest]

He can't break if he want to clean array

Just is valid>add array element to temporary array

[last peak]

Its just odd that the loop returns when it hits a invalid value

[rose crest]

Can you screenshot

?

[glass blade]

why is it odd?

[glass blade]

how do yo ucheck which value is valid?

[last peak]

Because i dont think thats how its supposed to work, but i cant remember for sure

[rose crest]

IsValid

[white parrot]

Because it doesn't, it just loops through all of the items

[glass blade]

yes, on the loop body pin

[last peak]

so it doesnt fire completed .....

Untill it looked trough all array elements

No matter if they are valid or not

I just tested it with a empty array / 3 invalid elements

[rose crest]

Let me guess, it's inside function and return node connect to loop body

[glass blade]

No

its in a plain event graph

[rose crest]

Screenshot it please

[glass blade]

no external factors, just the array has invalid elements

[glass blade]

its just a plain and simple for each loop node

[rose crest]

But how your validation logic works?

And what object? Actors?

Do you get console error for access none?

[glass blade]

thats what im trying to figrue out, i dont have validation logic yet

how would you remove the invalid eleements

[rose crest]

Use IsValid node

[glass blade]

from the array

[rose crest]

Told you earlier

[white parrot]

If you know their indexes, remove in place. Else, copy only the valid ones to a new array.

[rose crest]

Use temp array to cycle old array, Validate and set old with temp array values

[maiden wadi]

Are these pointers to objects? Is that what the array is holding?

[glass blade]

array is holding instanced structs

which has 3 plain variables

[rose crest]

...

You can't just valid check structure

Create your logic that verify values

[glass blade]

ok how you would valid check a float, ignore the struct for now?

the float can be any number

[rose crest]

What do you mean verify float?:D

[white parrot]

I'm not sure where the issue is screen-shotting your logic, but if it goes straight to completed means your array is not initialized

[maiden wadi]

That depends on your system. What is the float for?

[glass blade]

it prints out the values though? How is it not initialized

[glass blade]

What?

why does it matter?

[rose crest]

Ok, I ask simply. HOW do You know it's not valid?

[glass blade]

because it jumps straight to on completed

[jade kraken]

Hey peeps, I need a little support if possible. I've made my UI Widgets, and all of them work fine in PIE and Standalone play. But as soon as I package the game there are two widgets which refuse to work.

• Crosshair
• Interaction Prompt

Is there anything special that I need to do to get these to package and work properly?

All of my widgets are added the same way in the PlayerController, and then the crosshair is updated in the FPSPlayer at BeginPlay. But this does not seem to actually change the crosshair at all in the packaged build.

Same with the Interact prompt, this is updated to visible/hidden whenever the player looks or looks away from something that is interactable, but this doesn't work in the packaged build.

I've been racking my brain for a couple days so any help is super appreciated...

[glass blade]

because the very first item is an invalid value

if it would be valid, it would fire on loop body pin

[rose crest]

How invalid? How do you know? It will jump only if there's no array value, for example you remove value or index while looping

[glass blade]

yea there is no arra yvalue essentially in the very first item

then theres my valid value in between

the invaldi values

[white parrot]

But you said it prints the values, and also jumps straight to completed?

[glass blade]

Yes

[maiden wadi]

If your float is used for alphas, it can be defaulted to something like -5.0. So your IsValid can be as simple as an IsInRange check for -1.0 to 1.0

If you float is meant for world coordinates, you set it to a max float value and check if it's that.

It's just a number, and the use case of the number determines how you create a validity check for it.

[last peak]

there you go

[white parrot]

IsValid doesn't work for structs

[glass blade]

homie that is an object

[white parrot]

What happens when you print the array? how many members?

[last peak]

So you are looping trough a array of structs ?

[rose crest]

He does

[last peak]

Wtf ....

[glass blade]

4-5

idk exactly

[white parrot]

This conversation becomes more and more confusing by the minute.

[glass blade]

again,

1, Invalid
2, Invalid
3, Valid
4 Invalid

kinda like this

[rose crest]

You have to break struct and verify by your criteria

[glass blade]

it doesnt matter

because it will jump straight to on completed pin

which is not the proper behaviour

[maiden wadi]

Need more information on this. How do you pick your crosshair image, and how is that text set in your logic?

[white parrot]

If it prints 4-5 of them, that means it does not go into completed straight away, but loops over all of them..like it's suppose to, I'm not sure what you're struggling with, instanced structs do have IsValid (unsure if BP-reflected)

[rose crest]

Do you use anything that's engines? Assets

[glass blade]

its not bp reflected

[jade kraken]

Crosshair image is controlled by a function called at BeginPlay and whenever the weapon is swapped

The text, I'm guessing you mean the interact prompt is updated based on a line trace, if it hits something that has the "Interactable" tag

[jade kraken]

Nothing used from the engine as far as I can tell

[glass blade]

Can i make like a new array from the original "flawed" array and only save valid values?

[rose crest]

Mm, cast on tick. Anyway maybe just try to switch cross hair on demand and pass struct with images that's inside weapon class

[maiden wadi]

And I'm understanding correctly that the image you're seeing in packaged is a default or different image you intended to use and isn't updated correctly for the weapon you have?

[maiden wadi]

Casting on tick is fine. Don't do that.

[jade kraken]

The crosshair WBP is just two images that are exposed as a variable, and used in the ChangeCrosshair function

The images aren't different, but they are both being shown at the same time. I have no reason to assume that the code is broken as it works in PIE/Standalone, but the images visibility is not being updated properly in the packaged build

[maiden wadi]

I'm not certain for the interaction widget. But the crosshair makes me assume order of operations.

[last peak]

It is fine? How so?

[maiden wadi]

Better question. How is it bad?

Are you aware of what it's actually doing? Why is doing it on tick bad versus doing it at beginplay?

[last peak]

becasue it casts each frame thats useless overhead
Instead you could just cast once then do a validated get

[maiden wadi]

And are you aware of what casting actually does?

[last peak]

Yes???

[glass blade]

it wont cast it again if its loaded into memory already

[maiden wadi]

No, you're not. You're repeating things you've read somewhere and it's wrong. There is no overhead to casting.

[last peak]

So much you know about me from 2 messages
Awesome you must be a great mind reader

[glass blade]

once you cast additiona lcasts of the same csat will cost 0

[jade kraken]

Hmm, order of operations. Okay, I can try to initialise the crosshair first by delaying everything else hahaha

[glass blade]

my problem is,i want to trigger a different logic on completed, but not always

[white parrot]

So branch off from the completed pin based on the logic

[maiden wadi]

Casting, like ANY other pointer type causes linkers. This is not a runtime cost, this is a memory linker cost that keeps thing's classes loaded. This has NOTHING to do with runtime calls to a cast node. You can cause this without a cast at all where there is just an empty pointer to that type and ZERO cast nodes in the entire blueprint.

Cast nodes just also cause this because they have that output type.

A cast nodes EXECUTION is literally nothing but a pointer conversion and an if (Object) afterwards.

The act of casting a pointer is essentially free. The if statement costs more at runtime than a cast does because again it costs nothing.

[last peak]

Lets just do a typecheck every frame, why go for the better practice and do it once? Nah lets shove useless overhead in

[glass blade]

Yeah, but if it jumpst to on completed all times, then it isnt really a branch

[maiden wadi]

You're aware that a validated get or IsValid node is actually slower at runtime than a cast node, right? Because it checks more things?

[white parrot]

Could you show your code at what you're doing that goes straight to completed, it feels like a guessing game honestly.

[glass blade]

😆

[white parrot]

I know how the node looks, i mean in general what's going on.

[white parrot]

how about IsValidLowLevelFast

[glass blade]

but the tricky thing is, sometimes 0 can be valid

so i cannot elimintate 0 all together

[jade kraken]

What is the whole purpose of this bro god damn

[white parrot]

Show the entire graph my guy

[rose crest]

Loop body?

[glass blade]

yeah it will also trigger loop body

[last peak]

A cast does a NULL check, then a typecheck
A validated get does a null check

[rose crest]

Why it's not connected?

[thin panther]

a validated get does an isvalid check, which is different and more costly than a null check

I believe

[glass blade]

entire graph is irrelevant here its just this array is screwed up that i want to clean up

[last peak]

But not more than a typecheck

[thin panther]

I'd be very surprised if validated get does a simple if object

[last peak]

Ah guess in both cases it doesnt matter and the difference is probably negligible

[rose crest]

It jumps because it do the loop which is NOTHING

[glass blade]

yeah

[rose crest]

You don't think it's a problem?

[glass blade]

i definetly think its a problem

thats why im here

[jade kraken]

So... Why don't you have anything in your Loop Body then?

[jade kraken]

Order of operations worked for the crosshairs btw, thank you kindly

[glass blade]

because it will jump to on completed

even if i have loop body connected

since the first value is nothing

[rose crest]

https://tenor.com/view/nadeko-sengoku-monogatari-bakemonogatari-you-spin-me-right-round-gif-8180423662152633188

How do you set array?

[jade kraken]

Can you just show us the whole graph so we can understand better what is happening?

[rose crest]

It might act weirdly if you set for example index 2 skipping 0 and 1 in empty array

How do you initialize an array

Buy still it shouldn't and should contain default values inside struct

[jade kraken]

I fixed the interaction thing too

Authaer solved both things with one stone without even realising

[maiden wadi]

O.o How was that OoO?

It was on tick, or did I miss something?

[jade kraken]

I moved the interact widget initialisation to the beginPlay of the player and somehow that worked

I really have no idea

genuinely

PIE and Standalone was just gaslighting me into thinking it was all happening at the right time I guess

The OnTick update wasn't the real problem I suppose

[maiden wadi]

[slim lotus]

Sorry for the late reply, I was asleep and had to do a few things this morning.

I'm very new to blueprints, but I badly want to learn to be good at this stuff. this is what i managed to throw together after doing some research from any sources i could find, but i fear that ill have to sit down and memorize every thing else before I'm able to make this work. I know they are wrong, which is why im here hoping someone can tell me whats wrong and how to fix it. if its all wrong then id like to know the proper nodes to use.

the left is the Settings widget variables and event dispatcher and the right is the graphics widget variables and event dispatcher focusing on the Anti-Aliasing.

[faint pasture]

Wheres the part where you actually do anything to change the AA method?

[slim lotus]

I dont know, thats why im asking of anyone knows the correct way of doing this. i dont know what im missing. I know im missing the part that actually changes things, but i dont know what that is called/what im meant to grab. Its like knowing i need to grab a rock but not knowing what type of rock, is it granite, or basalt, etc.

[white parrot]

Isn't changing the AA just a CVar?

[faint pasture]

Can be yeah

[white parrot]

sg.AntiAliasingQuality <num> if i recall

[slim lotus]

so this node? are there any sources you know of that i can read to tell me what to use this with? such as telling me what to inject into target or the return value?

[white parrot]

Its a CVar, you can get it's value, or set it's value

There are 3/4 levels of AA, excluding 0 which is off, that's all there is to it

[slim lotus]

Yeah i know about the Off, FXAA, TAA, TSR. I just didnt know about how to make it all toggleable in a combobox. ill go do some more reading regarding CVar and then tinker around and ill get back to you on my progress. Thanks for helping.

[white parrot]

Well, in theory, user presses/toggles from off to AA1 -> SetAntiAliasingQuality(1) (or call the CVar directly)

[slim lotus]

Btw is there any Udemy courses any of you would recommend i get? This is currently what i have.

[rose crest]

Thank you thank you. i will go off and memorize this.

[rose crest]

eee

#nvm this select xDDD

i just asume if you text values

but you can simply just set int inside dispatcher and just pass int instead of text

[slim lotus]

How do i link this up with a combobox? do i do a switch on string? then branch off into the low, medium, high?

[white parrot]

Although it's better to broadcast all of the settings change into one place, valid yeah

[rose crest]

if you have child widget of main setting UI just use its dispatcher to get event on click. then pass what to do depending on button, there's many ways to do, try to make it work, I wouldn't focus on cleanses of code now, not too much at least

[slim lotus]

Okie, im trying to trial and error this so i can both make it work and understand this all. ill let you know if i make it work. 🤞

[rose crest]

you have 2 dispatchers there, but you really need only 1, inside widget with button

[slim lotus]

i have one in the settings widget and one in the graphics widget, the graphics is the "OnPendingAAMethodChanged", the settings is the "RecievePendingAAMethod" since the Settings widget is the parent to the graphics widget as im using a widgetswitcher in the settings panel.

[rose crest]

this receivepending.... is not necesary i think, but you might want to use it somehow later

[jade kraken]

How do you get the angular blueprint wires btw? Is it a plugin of some sort? :o

[rose crest]

yes, electric nodes

[jade kraken]

Oooo thank you

It looks so much nicer for my brain holy moly

[slim lotus]

Okie, ill refrain from using it until it is needed later.

[slim lotus]

Are there any plugins youd recommend i get?

[rose crest]

and AGR V if you deal with animation blueprint etc, but its not necesary, its just good and speed up things if you already know how to setup certain things with blueprints

just dont spend too much time on tutorials, try yourself, if you want to do something just try searching for node and connect things

Hello everybody ! I'm trying to make an object that reacts to light when being cast on it (a puzzle game with a moon and the moon light activates some pieces of a puzzle) and I can't quite find some ways to do it, does anyone has an idea ? Thanks in advance !

[faint pasture]

Actual light in engine? Very hard to do

A trace from the thing to the light source to see if there's nothing in the way is much simpler.

You basically have no access to the actual lighting information for gameplay purposes so you'll have to effectively make your own system.

[rose crest]

Make overlap sphere that collide with light actors. If detected ray cast towards light actors with custom trace channel, use visibility as blocker

[chilly root]

Can anyone tell me why does "ai move to" give out a fail pin when i click my unit to move to the center of top side of a square mesh, but when i click anywhere else on the cube, it goes to it normaly?

[distant grotto]

Any ideas why activating physics on begin play or construct isn't working?

its for an item pickup, so I want it to physics interact with the environment but not the player, but still overlap with the player. Thats why ive got a physics collision with a player overlap collision as a child, I had trouble doing both with one collision

actually it works on construct but only for the server, afaik you dont need to replicate physics?

[sick sky]

Seems like it isnt

[distant grotto]

looks like collision enabled is overriden when I run the contruction script?

its enabled by defualt

[dark drum]

As an FYI, if you want physics items, you'd normally need to have the thing that simulates as the root of the actor. If it's not, it'll simulate in local space which can give undesired results.

[distant grotto]

ah that probably explains why it spawns in the wrong place when i spawn it via the client

[dark drum]

Also, make sure you update collision before enabling physics. If it has no collision, enabling physics will fail. (Normally logs an error)

[dark drum]

If you're doing multiplayer, you need to make sure the component is set to replicate as well.

[distant grotto]

thats what I did. Only issue ive got now is the actor always spawns with an offset on the client, no matter if its the client that calls the spawn rpc or the server

Is there a way to override the scene root in child classes?

if I turn off component replicates it spawns in the right place but without physics

[faint pasture]

make the root component of that actor the thing that's simulating physics

physics replication relies on the root component being the thing

[distant grotto]

yeah i just tried that myself and it worked, problem is this is a child class so i cant set it as the root component

[faint pasture]

then change it in the parent

What's your goal here, why do GatherPoints have physics?

[distant grotto]

setting it as root in the construction script doesnt work right? or did i do it wrong?

[faint pasture]

don't do an RPC on begin play

What's your goal here, that the thing just starts simulating physics asap when it spawns or the map is loaded?

[distant grotto]

i got this part working, the defualt collision was set wrong

[faint pasture]

nope

you shouldn't have to do anything in construction script and CERTAINLY not an RPC

begin play happens everywhere. If the goal is that it just starts simulating physics just do that

begin play -> set simulate physics

[distant grotto]

goal is to be able to toggle if its enabled or not. Items on the map I most often wont want to have physics, items dropped by players I do want physics

[faint pasture]

the act of dropping should be when it's set

is a dropped thing a new actor spawn or the same actor but just detached and dropped?

[distant grotto]

new actor

[faint pasture]

just expose a bool or have the dropping code in the char set simulate physics.

[faint pasture]

why are you rpcing a spawn

don't

[distant grotto]

its enough to just set actor replicates?

[faint pasture]

spawning a replicated actor on server will spawn it on clients

Dropping an item should be like this:

Drop input -> run on server event
run on server event -> look at HeldItem or whatever -> spawn the item

inside your character or pawn

[distant grotto]

right but when a client spawns it wont spawn on server

[faint pasture]

client doesn't spawn it

client asks server to spawn it

hence the RPC to server

[distant grotto]

yeah thats what i was doing

[faint pasture]

Inside Pawn:
Client:
input -> run on server event

Server:
run on server event -> ??? -> spawn thing

Inside Thing:
Begin play -> set simulate physics based on bShouldSimulate or whatever

[slim lotus]

I need a bit of help again. So i understand the AA quality, however im trying to set up the combobox(String) for the AA Method. i believe i need to use a "Execute console command" node, but im struggling to understand if i use a "switch on string" or "select string" node, or if i need to have multiple "Execute console command" nodes.

[faint pasture]

can't you combine strings together?

[distant grotto]

begin play doesnt trigger on spawn though does it? only on begin play

[faint pasture]

it does

spawning is when play begins

begin play runs on begin play, on spawning, and on becoming relevent

[distant grotto]

oh nice

[faint pasture]

if you need to gate something by server or not just branch on HasAuthority

[slim lotus]

could you elaborate on what that means? do you mean like in a chain? having one after the other? do you mean like this? but what does that do?

[faint pasture]

you can combine "r.AntiAliasingMethod " and "3" into "r.AntiAliasingMethod 3"

[sturdy arch]

Posted here a few days ago but managed to fix my combo, not the best fix though since there's a half second between attacking and dodging where i can't do neither. But it's my first time making this. Ive heard from someone I can do gameplay tags or make an array but im not sure how to implement either of this

[faint pasture]

don't use a delay, use the montage itself

nvm, delay might be fine for the combo reset

show what dodging does

[sturdy arch]

something like this?

[faint pasture]

That's certainly cleaner

you could also just have a notify that represents when to reset attackcount

[sturdy arch]

Does that mean using more than 1 notify on montage?

[hardy merlin]

Any advice for profiling the performance of a particular blueprint? I've gotten as far as I can with insights in C++.

[sturdy arch]

Im using one that'll make me do another attack before that montage ends

[hardy merlin]

Short of putting scoped events on every C++ function it calls.

[faint pasture]

WHat's the BP do? This is in tick most likely, right?

[sturdy arch]

Not really sure how to and also the attack count doesn't work at all with the cleaner version

[past compass]

coming from multiplayer if i change a blueprint's logic, but i have that item class maybe loaded from a past save game, and i load into the game witht hat blueprint that i just changed, will it's logic be updated to the blueprnt changes that i've made? im almost 100 percent sure that it SHOULD be changed, but im baffled at what is happening rn

[dark drum]

Yes the logic will be updated, however, depending on the changes, the data itself (stored in variables) might not be compatible which might result in unstable results.

[past compass]

ok , might just reload this particular item to check. but yea i changed an "ammo" variable and somehow it is using a completely different varaible that is not hooked up at all (this was the previous logic), and there is nothing connected to that old logic, so makes zero sense why it would be giving me the value it is

[slim lotus]

HA I DID IT. HEHEHEHEHEHE

Now for AMD FSR. 😄

[slim lotus]

Now im stuck on scalability...

[maiden wadi]

Scalability is the same thing. It just has specific functions for each of them in the GameUserSettings.

[slim lotus]

is this not it?

[maiden wadi]

I would also recommend not going with a switch on string. But uh... sec

Do something like this. Much easier to repeat.

And when you get to localization, your stuff won't break because your strings change to Korean.

EG

For your AA

[slim lotus]

okie, but i got 3 graphics quality levels (scalability), low, medium, high. hence the switch on string so i can toggle whatever i want from the combobox.

[maiden wadi]

Right but you don't need the string. It's an integer level. And there are 5 settings total. 4 if you want to leave out the overbearing Cinematic.

[slim lotus]

The FXAA and TAA work but the TSR doesnt.

[maiden wadi]

Ah right cause..

Yeah. MSAA is in between them. You'd need an integer converter map to do that. You can also do a switch on int instead though.

Primary point is just to avoid the string switch that localization would break later.

0. AAM_None UMETA(DisplayName = "None"),
1. AAM_FXAA UMETA(DisplayName = "Fast Approximate Anti-Aliasing (FXAA)"),
2. AAM_TemporalAA UMETA(DisplayName = "Temporal Anti-Aliasing (TAA)"),
3. AAM_MSAA UMETA(DisplayName = "Multisample Anti-Aliasing (MSAA)"),
4. AAM_TSR UMETA(DisplayName = "Temporal Super-Resolution (TSR)"),
5. AAM_SMAA UMETA(DisplayName = "Subpixel Morphological Anti-Aliasing (SMAA)"),

[slim lotus]

This doesnt work. i dont see any visual change in graphics quality.

unless it wasnt meant to be for that...?

[maiden wadi]

I can't recall if that needs uhh.. What was the GUS thing. ApplySettings?

ApplyNonResolutionSettings, or something like that.

[slim lotus]

i got that.

unless youre thinking of something else?

[maiden wadi]

No, that should do the same thing as the scalability console command.

[slim lotus]

this requires a target, but i dont know what target should be inserted?

[maiden wadi]

GameuserSettings, same as your ApplySettings you're already calling.

I just checked that and it 100% applies those scalability settings.

[slim lotus]

oh... yeah i should have known that.

[maiden wadi]

ApplySettings internally calls the ApplyNonResolutionSettings though. So it shouldn't change anything.

[slim lotus]

yeah i dont see any visual change. the shadows are all still high.

[narrow sentinel]

So for some reason this code is returning false even though the hit actor does have the tag

[maiden wadi]

I have a vague memory of having problems with this in Atre a while back with scalability stuff, checking through what I'm running at the moment.

[maiden wadi]

Nothing else would cause that. Get your HitActor's Tags array and maybe print them to make certain. May have tagged the wrong instance or is that class defaults?

[narrow sentinel]

class defaults is where I've done it

[maiden wadi]

I'm not sure then. :/ Our code in Atre just sets the overall quality setting. The Scalability console command may work too if it saves it to the settings somehow. Could test with a cooked game. Editor does some weirdness with settings sometimes.

[slim lotus]

https://tenor.com/view/ariana-grande-barbiaminaj-glinda-ariana-grande-wicked-wicked-gif-3768134899335161969

Guess ill just have to power on and tinker for a while.

[narrow sentinel]

If i have a selected actor in debug dropdown box and set the tag array with the tag would it only do it on that one instance ? Thats all i can think would be reason for my issue cause i defo set it on class defaults

[maiden wadi]

I don't believe so. That is just for debugging stuff if I'm not mistaken.

The only way you should be able to set one actor instance's tags is through the world outliner, playing in viewport and ejecting to select them.

At runtime anyhow. Or doing it in the world details panel while not playing with them selected, either way.

You're 100% sure you're hitting that class with the trace?

[narrow sentinel]

Pretty sure i am yeah, ill do what you suggestes tommorow though printing the tags and hit actor to make sure

[fading raptor]

Hello everyone again ! I'm trying to setup states for my Moon (via Booleans for now) but it doesn't work.. When I rotate the whole object, it stays at "no state on" despite having a Y rotation of 90 and then 180

does anyone has an idea ? thanks in advance !

the only time it really detects and tells me its state is on state 1 with 0 degrees

[sand shore]

I mean I don't know what your goal overall is or the implementation or anything...

but something that may make your life easier is setting all the state bools to false at the start of the state check

but really you gotta investigate why your stuff isn't working

what have you tried, debugging wise?

[slim lotus]

@maiden wadi I figured it out.

[warm hare]

How can i achieve this? i Think I need to use geometry scripting, but I am unsure where to start. I have been trying to figure out how to make a twisting hallway for ages.

[maiden wadi]

Just visual or does it actually need to have that geometry for gameplay?

[fading raptor]

I found it, just some booleans not linked to branch nodes so not verification, automatically false and then not working 🙃

[warm hare]

The gif of it shows the hallway as a normal hallway and then it twists.

[maiden wadi]

Right. But is it just for display, or do you actually need it to twist the real geometry?

Like are we talking cinematic or gameplay?

[warm hare]

Gameplay.

This is all they said about it, but its confusing. So I need some clarification

""Create a DynamicMeshActor blueprint (Geometry Script plug-in required);

Construct > Copy Mesh from Static Mesh (or you can create a mesh from scratch, you will need quite some vertices for smooth bend/twist);

Apply Twist Warp to Mesh. This one is tricky as you need to multiply alpha from timeline (with a sin curve here) to 1 or so deg added through transform API, and aim at the duration needed (6 seconds for a 180-degree spin in my case);

For the gravity part, it's a bit more complex to share but look at the free Directional & Planet Gravity plugin + GetDistanceAlongSplineAtLocation to change the gravity vector with a spline at runtime."

So I am confused if I need to create a blueprint actor for this or what?

[maiden wadi]

Yeah. you'd need a new BP from that DynamicMeshActor class. I'm assuming you need to copy that hallway mesh or meshes into a dynamic mesh. Then you can affect it with the twists.

Presumably you could put the spline in the same BP and twist it and use that to alter the character's gravity direction

[warm hare]

I think I understand it. I am trying it now

[warm hare]

This is really my first time dealing with splines like this. When I add a spline, how do I apply the twisting?

[maiden wadi]

Spline points all have a transform that applies as a lerp between each set of points. So you'd probably want a few points that are rolled as they go down the hallway.

[warm hare]

so should I add a spline mesh to the BP or just a spline

[maiden wadi]

I don't think you need a spline mesh? I'm not sure on that though. If you're using the geometry stuff you can copy your meshes to that and twist that instead of morphing spline meshes with tangents. But either way might work.

[charred berry]

wth, BP in BP editor, all meshs can be selected individually, but putting BP into world from CB, and one selects all, is there a way to fix , and why is it different in BP editor ???

5.6

[maiden wadi]

That sounds kind of normal. In the world you care more about the actor. You can still affect it's components in it's Details panel though.

[steep oyster]

That is on purpose

[charred berry]

ok thx

[white parrot]

FYI, changing overall scalability settings changes AA, so its a little redundant.
You could set it to 'Epic' on scalability and then off on AA, then it's no longer epic (or any of the options) or changing the AA and then scalability and then AA is overwritten.

[slim lotus]

im just wanting to change the graphics settings. but im putting that on a pause until i have my pause menu sorted so i can see it change without having to constantly reload the game.

[hearty rain]

Hey people, I'm using Gameplay Ability System and I would like to have a character broadcast that his tag has changed to everyone around. It's for instance when an enemy dies, its stops your character from targetting it. Any ideas on a clean way to do it ?

[dark drum]

It's been a while since i've used GAS but I believe there's an event dispatcher that gets called when the tags update. Have the thing that locks on bind to it. (unbinding when the lock on is cancelled)

When its triggered, the thing that create the binding can then check the tags when its triggered.

[hearty rain]

I'll see into that thanks

[hearty rain]

Ok I did it kind of "backward" by binding to an event related to the enemy when the lock on ability is activated. Works but I don't really like the look of it

[dark drum]

It's not to bad, however, I would avoid calling the 'Unbind All Events' from outside the class that holds the event dispatcher (unless its from some sort of manager class) as it will also unbind all the events other classes might have made.

I've ran into a few issues where I unbind everything. 😅 Took me a while to track it down.

[hearty rain]

Wait, this mean it can unbind the events that are being bound in other, external characters ?

I'm going to replace this by a "global event bus" message dispatch anyway, for even looser coupling

thanks for the heads-up, I wanted to avoid "floating unbound events"

[dark drum]

Pretty much. An event dispatcher is just an array of delegates which specifies the object and function name. So when you call the event dispatcher it loops through the array, calling the desired function on the specified object.

Unbind all just clears the array.

[hearty rain]

Makes sense now that you explain it this way. I'll just unbind this specific event then. Thanks !

I guess in the array it will be something like ThisCharacter->ThisCallback

[maiden wadi]

BP really needs C++'s RemoveAll version for delegates.

[dark drum]

Yea, it would be nice if BP just got more support for delegates in general as well. Being able to create and store an array of delegates would be nice.

[hearty rain]

better ?

[main lake]

Hey, 🙂
Is it possible to create a game :

• made out of blocks like in Minecraft where you can break and place blocks but
• the level is limited to a 256x64x256 (width,height, depth)
• there's no procedural generation as the level will be built block by block by hand
• in BP
• Without it being laggy

please ? Because i received 2 different answers :

• 1 saying it will be laggy because of the amount of blocks, so you need to go through c++ for optimization (when I tried with static meshes, indeed it lagged alot with less than that (I think I tried with 100x100x100)
• 1 saying the 256x64x256 size isn't really that big, so it's doable in BP (this answer came from one of the creator / dev of the Voxel Plugin on their own discord)

So if that's possible to do in BP, what approach and things should I go for / know about to do my game please ?

[next hollow]

Perhaps instanced static meshes should work, at such a small scale.
You could also use the voxel plugin. 😛

[dark drum]

Short answer is yes. The biggest hit is actually the calculations for procedural generation which you've stated you don't want.

[main lake]

• Are there limitations to instanced static meshes ?
• So for instance, if I fill the whole grid of 256x64x256, it won't lag ? Even with the faces overlapping each other that shouldn't be rendered ?
• I want to use the voxel plugin but the issue I have with it is it's doesn't support custom blocks such as stairs (I asked that 1 year ago, so I don't know if they finally added that option or not) 😬

[next hollow]

I shouldn’t lag.
Instanced meshes is what games use for trees.
And there’s a shit ton of those, with a ton more quality in comparison

[dark drum]

At that size, it would be over 4 million blocks. The issue with ISM's is they can cause lag when trying to add/remove an instance when it has a ton already.

However, if you chunk the area and then frame slice updates, you should be fine.

You could even add addition checks to not add instances for blocks that are blocked on all sides.

[main lake]

By how much could I increase that size and still not being laggy ?

[dark drum]

That would depend on your implementation. You'd have to build it and test.

[next hollow]

Hard to say.
I didn’t even realize in my head, 256 would mean 16 million…

[main lake]

No, not 16 million, I'm not using 256 in height, I'm only using 64

[next hollow]

Oh
Still 4 million. lol

[main lake]

Yeah

[main lake]

What should I look for on youtube to learn how to do the frame slide update thing, because I have no idea what that is 😬 ?

[dark drum]

Lets say you have 16 chunks and they all need updating. Doing so all at once would most likely stall the game thread. So what we can do is update 1 or 2 chunks each frame (like a queue) until all updates have been completed.

You effectively slice up what needs to be done into smaller batches and handling them over several frames.

I'm not sure of any specific tutorials.

[white parrot]

Placing 4 million blocks by hand? sounds fun

[main lake]

I see, but to create this kind of chunk system, we need a kind of tree data structure, isn't it ?

[dark drum]

Its a speed run type game. 😉

[main lake]

No but like 4 millions is my canvas, I don't have to place blocks in every one of them 🤣

[dark drum]

Yea, you'll need some sort of manager class.

[main lake]

Is there a prebuilt type in BP for tree data structures ?

[dark drum]

Data is data, how you choice to store it is up to you.

You just need to make sure the manager class is able to work with what ever structure you go for. (Get and set data within it)

Personally, i'd probably go for an actor component for the manager class (placed on the game state) and then use a custom uobject for the chunks. This would store the blocks that should be in the chunk with their relative locations.

[wide beacon]

Hello, I'm trying to make 3 drones spawn in the box collision that's acting as a bounds, but I just cant seem to get it to work, I'd, appreciate any help thanks 🙂

[main lake]

Oh so I have to design the tree structure myself, I thought there was a tree data structure by default in Unreal that I can use like there's an array structure type, map structure type, etc...

[dark drum]

I've used a TMap<IntPoint, ChunkObj> before which wasn't to bad.

Then you could have a 'PendingUpdates' list of IntPoints that need updating.

But yea, there's no one size fits all approach, you need think about what data you need and the best place for it to be stored.
