blueprint

[spark steppe]

there's no table

wrong channel

and most likely that's just how the thin faces on the sign look like

as the DOF is fine on the post

[sacred birch]

Alright. Will be doing that.

[limpid nebula]

But how do I make him turn smoothly during navigation and also when using set focus and default focus?

[lunar sleet]

Change the turn speed

There’s a setting in the CMC for it

[limpid nebula]

But will it work when the inherit controller rotation yaw is set to true?

[merry chasm]

Yes, that was a typo; my apologies. Thank you for the tip. I reduced the aperture, and it has improved. Do you believe that the sign edge is physically accurate in terms of depth of field, or is it a limitation of the engine when using thin faces?

[spark steppe]

the side of the sign just looks like ass in the asset (my guess)

might be a mix of material and mesh issue 🤷

[fallow estuary]

Left is my screen Missing the blueprint section and right is the person who I am watching the tutorial to make a game project
I can't find the "my blueprint section" I am a complete beginner never used Unreal before So If anyone can help in telling me how Can I get the "my BP" thing

[dark drum]

It comes down to what you're casting too. If the actor would be loaded anyway then it wouldn't make a difference. Learn about class hierarchy, it'll help you greatly when it comes to better memory management.

[dark drum]

Under the 'window' menu on the top nav bar there should be options to show the different sections of the UI. There should be one for my blueprint.

As FYI, if the actor is a child actor component, if the pawn is destroyed, the actor will be destroyed as well. This of course might not be an issue but just something to be aware of.

[fallow estuary]

Yes thanks!

[silk bay]

I disabled some Virtual Textures but the materials didn't recompile correctly. Is there a batch way I can do this? I tried "recompileshaders all" console command but that didn't work. I'm getting this error when packaging: is marked for virtual streaming but virtual texture streaming is not available

[limpid nebula]

But he is turning instantly when using default focus. Any idea?

[grave relic]

Guys, how do I destroy a Spawn 2D sound? I can't find how to do it?

[maiden wadi]

The pin that it returns is a component. You need to call Destroy on that.

[grave relic]

Yes but it's not working or am I doing something wrong?

[maiden wadi]

Unsure. Try also calling "Stop" before the destroy.

[grave relic]

I'll explain, so you can see the code.
Basically, I have a button in the lobby that displays the "Credits" widget.
In the lobby, I have the music that Unreal Engine offers "Starter Music".
On the Credit Widget, I have another music.
So I have to ensure that when the player clicks on the "Credits" button it deletes the music from the lobby and starts the credits music.
When the credits animation is finished, I have to destroy the credits music and put back the lobby music.
If, on the contrary, I leave the credits with the "Back" button I destroy the credits music, hide the widget and restart the lobby music.

[maiden wadi]

I can generally see that. The AudioComponent has a function called Stop. You should try calling this before calling Destroy, to see if it stops the credit music.

[grave relic]

It stops the music when I do "Back" but on the other hand, the lobby music does not come back

[maiden wadi]

Are you using CommonUI?

[grave relic]

Huh?

[maiden wadi]

I'll assume no. RIP. In that case you need something like a dispatcher in the credits widget to let other things know when it's removed. EG The lobby widget can bind to that and when the credits are removed, it can restart it's own music.

Otherwise you need to make a system someplace global like an AHUD or similar where you can push and pop widgets and their music on a priority list and update the music when the list changes.

[grave relic]

If I create a Switcher in the same widget, is it ok?

[maiden wadi]

Could also work, yeah. Changing it based on the index.

[grave relic]

Yeah

[faint pasture]

Do you know anything about programming at all?

Like, do you know what a variable, function, class, instance are?

If you know those basics, just familiarize yourself with the framework then start trying to make the computer do something cool.
https://dev.epicgames.com/documentation/en-us/unreal-engine/gameplay-framework-in-unreal-engine

[grave relic]

So I changed and it tells me the same thing as before "Blueprint Runtime Error: "Accessed None trying to read property Lobby Audio Components". Node: Stop Graph: EventGraph Function: Execute Ubergraph WBP Main Menu Blueprint: WBP_MainMenu"
The music stops fine though, I also tested with the destroy but it's the same thing.

[versed sun]

It is probably the first time you run it , the Lobby Audio Components doesn't exist
Try Convert to Validate Get and do this

If it Exists , Stop it and move on
If not , move on to next thing

[grave relic]

Yap Good!

It works for that, I'll see if the rest of the code works, I'll keep you posted

[grave relic]

With this it only works once.
No problem with the credits, but on the other hand the music in the lobby works once. That is to say that if I do it a second time, I have duplicate lobby music and so on...

[versed sun]

Are you spawning each sound as needed?

[grave relic]

I only have two sounds at the moment.
That of the lobby and that of credits

[versed sun]

I would have Lobby music just spawned once and never make a new one or destroy it, Just Play and Stop it

when you want credits:
Stop Lobby
Spawn Credits and Play

Back to Lobby:
Stop and Destroy Credits
Play Lobby

[grave relic]

Stop and Play node?

?

[versed sun]

or try

for lobby

you can pull off of your Audio Component and type 'audio' so see all the nodes you can run with it
Fade In and Out might be cool
Pause can retain your play position

[storm vigil]

whats the difference between pre-event graph and thread safe when using property access in the animBP. I mean are they both optimized and have their own path? Thanks

[grave relic]

Yap fix

Thx

someone can help me with this? i think the problem in the Level, but after i search the white screen problem come from blueprint, hiding ui not working, change from cine camera to normal cmaera not working

Why is my reference to the player invalid

[silk bay]

are you making a multiplayer games?

[final berry]

Hello! I have defined a custom event in a parent class, now I want to expand on that cusotm event in a child. So when that event is called in the child it executes the parents logic attached to that event as well as the new logic in the child. If I implement the custom event in the child it seems to override the logic in the parent 🤔 Does anyone have a suggestion on how to achieve this without overriding the parents logic in that event?

[autumn pulsar]

yeah that's fine, thanks for the heads up

[narrow sentinel]

anyone know if theres a way to uncook a cooked piece of content ?

would it involve altering the source of UE to make it happen or is there another way it can be done ?

I'm bassically trying to uncook a simugraph asset which is you are aware of DTG and simugraph that they put together. Thats what I'm trying to uncook

[maiden wadi]

Right click the function. There should be something about adding a call to the parent function. Will make an orange node of the same name.

[final berry]

Ah there it is, was trying to find that (like BeginPlay etc has by default if its a child, but couldnt find it 😅 Cheers!

[faint pasture]

because pawn owner doesn't exist in the animbp editor

[raw steeple]

Yup I understood the issue later thanks for the help by the way

[wary phoenix]

is it possible to connect a transformation of bones from one skeletal mesh into another that have the same name as the bone?

[wise ravine]

Hi can someone help me understand why my character isn't tripping off this door's hitbox?

[tropic peak]

show your on overlap event

[rose crest]

cast fails?

[crimson crest]

Have you tried with On Overlap?

[trim matrix]

What he said ^ , also if that doesn’t work, try getting player character instead of pawn. I’ve had issues with overlaps and the Player Pawn before.

[wise ravine]

Yeah for some reason On Hit wasn't working

On overlap works tho so thanks both of yall

[wise ravine]

I cast to the pawn so the BP doesn't have to reference the character which takes up memory. I actually don't know why, but when hard refing the pawn it doesn't appear in memory

[grave relic]

Quick question, is there a way to find out the minimum and recommended requirements for an Unreal Engine game? Is this possible with direct Unreal Engine or not?

For my game

[maiden wadi]

Profiling and testing different hardware. 🤷‍♂️ I'm sure there are overpriced services out there that'll do it too.

[grave relic]

Unity offers something like that, Unreal Engine doesn't?

[tribal flume]

I have this set of nodes that try to spawn a series of actors by taking each tuple from a map, with an vector as the key and the actor class as the value; it iterates through the map and tries to spawn an instance with the class set as the value, at the location set as the key for the map container. However nothing is spawning. I have printed out the spawned instances to confirm if they have spawned and apparently they have. But for some reason, I can't see those spawned actors

Am I doing something wrong

[lofty rapids]

is the display name printing ?

[tribal flume]

Yes

That's what's confusing me

[maiden wadi]

I'd be curious to know how they do it. Because unless it is ran on a cooked game build and profiles it through a bunch of actual gameplay, it isn't possible.

[lofty rapids]

print string the class from the find and the array element

make sure what your looking at is correct

[narrow pendant]

I have noticed that draw debug [shape] tends to lag behind the actor / component location slightly, should I worry about that?

[tribal flume]

It's printing the classes and instances fine. But still not spawning anything

Maybe I'm storing the vectors wrong?

No, I'm storing them correctly. I just printed them out at runtime

Wait is this happening because I called a function right after changing level?

[odd kiln]

Hi all !

Anyone know how can I stop all animation from Animation Blueprint and play a Montage ?

I tried to use "Set Anim Instance Class" to "null" then use a "Play Montage" node but it's not working

I also tried the "Set Animation Mode" node but not working neither

[maiden wadi]

Why do you need to stop other animations? Montage should override them with it's own stuff.

[odd kiln]

Ok I found the issue sorry I had another "Play Montage" in my "Event On Landed" node

Sorry guys !

[lofty rapids]

maybe the data is resetting ? are you populating dynamically ?

[gusty shuttle]

Quick question: How does one enable and disable a checkbox using a dynamic material instance? Is there a specific node to look for? I'm used to changing scalar parameters and vectors but not true or false systems in a mat instance

[supple dome]

cant

[gusty shuttle]

Aye, thanks for answering

[supple dome]

quick workaround is creating two instances and swapping

[gusty shuttle]

Humm, would be wonky but workable. I'm just thikning of changing the colors to black than white-ish haha. It's for a lightbulb flashing

[supple dome]

you can use a lerp with 0-1 instead of a bool

[gusty shuttle]

Yeah, that'll work

[supple dome]

bools are evaluated at compile time and will discard everything from the other branch

[mild jacinth]

is it possible to display the high res screenshots that were taken using "HighResShot" console command

like if I use widgets for this, what am I looking for exactly to load these images?

is there a function which returns an array of screenshots?

[pulsar vigil]

hello i have an error of access about a blueprint function library function that i use and work perfectly fine but this error pop for no reason any idea from ur magic hat guys ?

[dreamy sail]

is there a way to load a different map as default after a certain event happened in the game ? And if so, in what blueprint ? does eventbeginplay have priority over the project settings? I tried doing it in the player character BP, but once the level opens it freezes

[pulsar vigil]

i found the exact point where the error pop but i dont even know why xD

[dreamy sail]

I want to change the default map with a different one after the player has reached a certain level, i have all the logic for that already, but I don't know how to make it actually work

[shut tinsel]

Hello, is it possible in the editor to set the equivalent of a "data breakpoint"? I'm trying to figure out where the location is being set of my Player Pawn on startup from a downloaded sample project.

[trim matrix]

Can someone help me with this?

I am new to Loops. The issue I am having is that when the event is called, it completely skips my delay, shoots out a line trace and breaks the loop even though the trace didnt hit the actor I have it set to

[old aspen]

More that your delay node is making your loop asynch. So youre getting a 1000 5s delayed bits and your loop still goes. This thread has more details and some ideas on how to get what youre after: https://forums.unrealengine.com/t/how-do-i-add-a-delay-to-each-iteration-of-a-foreachloop/284709/3

Basic question but one I havent dug into in awhile. Do Boolean nodes in BP support early exits? like if the top condition is simple to calculate and returns False, will an AND nod bypass computing the other half?

[lunar sleet]

Why would an AND node bypass the second condition?

[thin panther]

if condition 1 is false, it can never be true so you can exit early. It's called short circuiting, c++ has it, bp on the other hand, no idea

[lunar sleet]

Ok, but you’re never reaching the AND node then

You’re skipping it, technically

[eager thicket]

is it possible to change the simple collision of a static mesh at runtime (change its position etc)?

[lunar sleet]

Anyways make more sense the way you put it lol

[thin panther]

no

It's a static mesh

[lunar sleet]

I don’t think it exits early tho, based on my xp using breakpoints on AND-chained branches

Least it doesn’t look like it skips anything as the bool pins show actual values not out of scope or anything

[onyx bridge]

Hi I got a Marketplace Asset that I'm following a tutorial on how to merge with my cuurent project and I get this error message when adding the BPI Interface to the Player Character

[silk cosmos]

Your character must already has a function called GetSpeed. i.e. you have naming conflicts

[onyx bridge]

oh so that's what it is?

naming conflicts only? So I have to change the naming conventions?

[onyx bridge]

TY man

[torn urchin]

Does anyone know if it's possible to make this sort of game in ue? I'm trying to add this sort of mechanic to my game but I don't how or where to start. I already have side scrolling mechanics and I want the player to be able to interact with an area and transition to this management style

https://nachogames.itch.io/thats-not-my-neighbor

[thin panther]

Of course. UE is just an engine, you can do whatever you want with it.

[old aspen]

Yeah I was pretty doubtful it would, and yeah Acuppa certainly explained it better then I did heh

[torn urchin]

yea, I just don't know how to get started with implementing this sort of mechanic 🤔

[thin panther]

Well it depends what mechanic you want from that game. If you just want the perspective, it's just a pawn that never moves, and a bunch of things that respond to click events.

[torn urchin]

hmm, and would I have to create a new game mode or level for this?

[thin panther]

Not necessarily. It could be a streaming level, an area in the map you teleport to, or a seamless in level transition. It's up to you

[torn urchin]

I see

thanks for answering

[copper chasm]

Does anyone have any resources for learning casting/event dispatchers in BP? I'm trying to have an element show up in my overlay when you mouse over an object, but I'm in the weeds on which BP should be casting to which BP. Every time I think I've made progress, I realize I'm just making spaghetti

[foggy escarp]

Where are you constructing the widget for the overlay? @copper chasm

[copper chasm]

Like, the overlay widget itself, or the widget I want to go inside the overlay? 😅

[foggy escarp]

The overlay

[copper chasm]

The HUD constructs the overlay widget in CPP atm

checks the widget class, the controller class, then constructs it and assigns the widget controller

[foggy escarp]

Are you also doing the hover trace in the controller?

[copper chasm]

It doesn't look like it, so I was just calling overlap in BP

[foggy escarp]

This is a overlap interaction? So the player walks near a object and a overlay pops up?

[copper chasm]

mouseover interaction

[foggy escarp]

Ah, ok

Where ever you are doing the trace you can construct the widget while while. You are looking at the object. Because you are constructing it you already have the reference, you just need to save it as a variable.

If you need to add the widget as a child to another overlay widget, you can add it instead of adding g to viewport separately. It depends on how you are creating that initial widget.

[copper chasm]

i found the cursortrace, it's in the player controller, and i see what you mean re: looking at the object

I already have a function to put a highlight around the target, I can build on that to get the info

[foggy escarp]

I'd recomend to first get a print string to make sure the hover trace is working as expected, then work to the next Iterative step.

[copper chasm]

Well, the highlight functionality works, wouldn't that suggest the trace is working?

[foggy escarp]

Yeah.
So you want to add it as a child to a different widget?

[thin panther]

Casting is quite simple and overcomplicated by lots of people.

It's a type check. Checking if a type is a specific child class so you can access things specific to it.
For instance, imagine you have a person, and you want to check if it's a friend. You could cast the reference to the person to a friend, and if it succeeds, you know you can access things that you should only be able to access from a friend.

Another example might be. You have a reference to a piece of furniture. You specifically want to check if it's a chair so the player can sit on it. You could cast the furniture reference to the chair class, and if it succeeds, it gives you a nice casted reference to a chair, that lets you do chair specific things with it.

[copper chasm]

I made a healthbar, and I want it to show up on my overlay only when I'm hovering over an enemy, and be destroyed when I stop hovering the enemy

I might be better suited to just try and add it in to the CPP, I just thought it might be easier to conceptualize with bp

[copper chasm]

I'm gonna save this and put it in my notebook

[thin panther]

Another thing to add there, is an important caveat. If the class isn't already loaded, it force loads it's default object into memory, which is expensive if the class has assets, like models, textures, sounds, etc.

Always make sure you have a base class, that only has the code, soft references to assets, or empty hard references to assets (hard references are the blue ones). That way, you pretty much nullify the potential cost of casting to classes that aren't guaranteed to be loaded.

For some classes, this matters less (things like the game mode, the player, the HUD, etc.)

[shy herald]

can some one help me out im trying to change a image on a widget but i cant figure out how

how can i use this funcion in a different blueprint

can someone help me out

with thsi

this

[small coral]

Have you tried using the set brush from texture node?

[shy herald]

no

ill try it

its not letting me use that anywhere in the blueprint

@small coral

[graceful sage]

Drag off the image widget reference

[small coral]

@shy herald

[shy herald]

how would i make a reference

?

[small coral]

Drag off the image variable that you have

[shy herald]

i moved from unity so im still learning

[small coral]

and select Set Brush from Texture

[small coral]

It's all good

[shy herald]

how do i make a image ref

[brazen stirrup]

anyone know whats going on here?

[brazen stirrup]

I renamed a asset, and now it has two references

[small coral]

drag an image into the widget

@shy herald

[graceful sage]

When you put image in your hierarchy of the widget make sure is variable in checked in top right when you select that then in the graph you can drag off ans set brush from texture

[small coral]

Click is variable so you can access it in the event graph

[graceful sage]

Redirexfors are created when moving or renaming an asset. You can filter to see these in content browser by selecting show redirectors

[shy herald]

this?

[graceful sage]

Then you can right click and update redirectors on the file of folder containing it

[graceful sage]

Yes

It should show in the event graph now

[small coral]

Yep

It should appear in the graph now

[brazen stirrup]

I see, thanks so much!

[shy herald]

so can i only change a image using blueprint inside of a widget blueprint?

[small coral]

Yes

[shy herald]

got it

[graceful sage]

Of course if you have a reference to the widget in.another bp you can change there

[frank locust]

Any navmesh chads in the building? I'm generating a grid of instanced meshes and I'm trying to figure out how to make certain tiles navigable or not. Everything I've found on navigation has been things that have to be done in editor, not with code or blueprints

Is it actually as simple as just using two different instanced static meshes with one allowing navigation data in its properties and the other one not?

[chilly gazelle]

I'm running into an odd issue where I'm trying to update the max walking speed on my AI, but it isn't working. They're performing the action, but the speed won't update. I am trying to set the movement component speed in the parent class, which is where the action is created and configured. Every other aspect of it works though. Any thoughts?

[graceful sage]

Screenshots?

[chilly gazelle]

so this is how I'm setting it. So the third screenshot switches the walk speed when sprinting, but that doesn't seem to work. I'm about to follow up tho and make sure i didnt do something dumb. I know its unconnected atm tho, that was for testing

[graceful sage]

Where do you set the repnotify bool?

Also ai only exist on servers

[chilly gazelle]

ah good point, I'm testing that now. I'm only doing SP but this asset is set up for MP as well

ok, so they think they're sprinting (i did a print stmt) but the speed just isn't updating in their movement component

[graceful sage]

Can you show more context

Where the function is called and is sprinting is set

I could be wrong but ai only exists on server so I'm not sure a repnotify would be appropriate

[chilly gazelle]

sure, so i have an event that the AI handler exectures to start a bayonet charge. You can see that here. The setup bayonet charge node is where the speed is set (shown above but can send again if needed). Everything else works perfectly, its just this interaction with the character movement component.

and the above shown event sits on the AI character BP

[graceful sage]

I still don't see where you set the repnotify bool

[chilly gazelle]

this method works fine for my character with no problem, and I also set up print statements to make sure its firing on the AI and it is

[graceful sage]

Try without the switch or try authority

Have you tried breakpointing to see if it gets called

[chilly gazelle]

yes I just tried this. And no dice on removing the switch, nor on using authority.

[graceful sage]

The bool in the function may not be updated in time

The repnotify function

[frosty heron]

have you tried introducing delay when testing your game

that should not work

may seems working when doing fake test (0 latency)

but the moment some ms is introduced you will get de-sync

[chilly gazelle]

no i haven't. I'm just doing singleplayer, this asset is just made for either MP or SP.

[frosty heron]

SP and MP are just architecturally different, you probably should just get a SP assets or roll your own imo

[chilly gazelle]

huh, so I just printed out all the values, and its being set, they're just not walking at that speed for some reason.

[boreal crypt]

When using a spline mesh, is there a way to control how many meshes it places? I have a mesh that is being warped, but it would look great if I could get it to repeat the mesh more often

okay, nevermind, I realize it is not at all stamping the mesh multiple times, just extruding the single mesh along the entire spline 🙂 I'll adjust to stamp my own mesh along the spline at a given sample rate

[astral orchid]

Question: is there a good tutorial or documentation that teaches you how to use the GameMode class (not GameModeBase) and it's match states to create, let's say a TDM?

[storm vigil]

are collision/trigger boxes always on tick? as they always check if there is an overlap? Thanks

[vagrant cobalt]

an error that is bugging me for a while, maybe you can find an idea of what could cause this problem... I have an array of platforms information that I fill in when the level opens that keeps the transform of platforms then I destroy the actors. For some reason, some of the platforms will show as if they are at the center of the world.

[lunar sleet]

Is your collision set to default on the platform spawn?

[crude dew]

Hi, Does anyone know how to "restart" a specific Timer Handle please? I have a Damage Over Time system which applys the damage every 3 seconds but if the enemy is hit again I am finding that its starting a second Timer By Event function, Which leads to having overlapping DoT's, Where as if the enemy is hit again I want to add more damage to the already existing DoT Timer Event.

I,ve tried a if the enemy is affected by DoT boolean which turns on when a DoT is applied and then when the timer expires it resets it to false and then checking that bool to find out if need to apply a new DoT or just restart the current DoT system and increase it,s damage but this doesnt seem to work this way

[lunar sleet]

Interesting, so you’re only getting 0,0,0s before destroying them or are they spawning at 0?

[vagrant cobalt]

before

[lunar flower]

Anyone know how I can change this actor to allow AI to move to the mortar? Not sure why the actor changes the navmesh so much

[frosty heron]

Adjust the nav mesh setting. Play around with the radius, etc

[warm python]

Hello. I'm trying to spawn an actor from a class (a projectile) but the spawned actor isn't simulating physics. it's stuck in the air.

[frosty heron]

Are you using projectile component for your projectile?

More info and screen shoots would be helpful

[warm python]

just this

the projectile (cannonball) is just a sphere

[frosty heron]

I never use impulse but my guess is you probably have to simulate physics on the component of the actor you want to launch

[hushed berry]

Hello, I've been told that (get all actors of class) is terrible performance-wise and I should use something else, for example (get actors with tags), but trying to look into it, I found this. https://forums.unrealengine.com/t/get-all-actors-of-class-vs-get-all-actors-with-tag/155107/3 which states that not only is it not better, it's also almost 4 times slower. I also heard that (get all actors of class loops through all the actors in the level and checks if they're of a certain class). From the statements in this forum post, that seems also to be not true. Right now, I'm pretty confused, as it's the only source that contradicts a statement that is repeated on almost every forum/reddit etc. post.

[frosty heron]

@hushed berry it should just iterate over the given type

So for player character, it will just iterate through all the player characters in the world

The question is why do you need to use it most of the time?

You can use it when you actually need to get every single actor of the type. But when you don't need every actor of the type in the world, don't use the node?

[hushed berry]

Well, it's pretty self-explanatory. You use all actors when you need all actors, but I don't get the stigma this node gets and all the shmacky workarounds people do to get the same result.

[frosty heron]

Most newbies use it when they don't know how to pass references

And their game breaks for obvious reason

If you do need to get all actors of a certain type, just use that node imo.

If you don't suffer from fps drop then all is well

[hushed berry]

Will do that 😄 Thanks

[frosty heron]

Ppl are scared of the node comment that says its a slow operation when you hover over it.

But if I can recall some cpp guys said otherwise

It will just iterate over the type instead going thru all unrelated actors iirc

[hushed berry]

Yes that's in the article inside the forum post.

[crude dew]

Anyone know how we can print values over as the integer max is 2,147,483,647, So even if i tried to multiply this value by 2 and print it out it wouldnt work properly, So how does Diablo do this please? I tried changing from Int to Int64 but it still fails to print out values higher than 2,147,483,647

Or that 259,140,553,035,177,000,000 Damage is in reality 259,140 and they just assign a bunch of random stringed digits to the end of it, So actually "lying" to the player about the actual damage being done? JUst as thought?

[versed sun]

Floats go higher

[frosty heron]

That's a lot of damage 🤣

[versed sun]

I would prefer looking at 4-6 digits and an Exponent

[next hollow]

The way I've seen it, and made me like fully understand it.
The node itself GetAllActorsOfClass is stupid performant.
But, the stuff you do with the output matters.
Sure, you can instantly get all your enemies.
Getting 2K enemies will be instant.
But, then your own custom code will loop over those 2K enemies to do stuff.

Similar to the "issue" with GetAllActorsWithTag, has to loop over 2K actors dynamically.

TLDR:
You can get 2K enemies, but it'll cost performance to tell 2K enemies to all attack, or move somewhere

[crude dew]

Ah thanks.

I changed to using a Float Variable which gets passed to a Floating Combat Text but the text still shows -2,147,483,648 when it comes up not sure if its a limitation of Text when converting Float To Text?

try Float to String, String to Text ?

[crude dew]

as you can see the value passed is negative.

[frosty heron]

Convert it to string and pass a string instead?

[crude dew]

But that will still show a negative value wont it ?

but just as a string because you are converting "-2147483648" to a string value.

I know Unsigned ints can go higher but maybe thats not available inside a blueprint?

[frosty heron]

Don't pass a float, pass the string

For the input param

[spark steppe]

do you think that players want to read such numbers?

someone started with this stupid shit and now people copy it

[frosty heron]

I would think the game dev doesn't know how to balance

[crude dew]

Most likely not but I like to try and challenge myself, So i challenged myself to recreate a damage which "could" show Diablo style damage.

[spark steppe]

you challenge yourself by asking for a solution here?

[crude dew]

well isnt this a discord for asking advice and help when you get stuck? as there is a lot of helpful people who are far more knowledgeable, And I have tried googling for an answer to no avail.

[spark steppe]

ok... use a uint256 and make a custom text formatter

the max value is 115792089237316195423570985008687907853269984665640564039457584007913129639935

[crude dew]

Ok, So i,ll have to use some C++ for this then, Thank you for the answer, So looks like Blueprints limit your int values if you want to print them.

[spark steppe]

you are limited to int64 in BP

which still goes up to 9,223,372,036,854,775,807

[crude dew]

I tried changing to a int64 but it showed the same value of negative.

need to pop out back a bit later thanks for the info!

[mild jacinth]

is there a way to see what cascade particles are being triggered with their display names visible

like collision box debug draw

[frosty heron]

@crude dew

scrap the idea tbh

Why would anyone want to see zillions damage

This works too, the issue was you are converting number to text, which has it's own formatting

just convert to string and call it a day

[jolly delta]

i am having some issues with the collision of my character with the bullets. I have set onactorhit event in the bullet class. And a check (with component tags == 'ignore') whether the other component hit is the capsule or the mesh, as I want it to hit on the mesh only. On the capsule too, I have set 'generate hit events' to false, and true on the mesh.
But when I draw a small debug sphere at the Hit.ImpactPoint I see its only on the capsule. Not on the mesh. The collision settings are also attached above.

[limber parcel]

i guess most cpp guys also use cpp base class though, which makes a big difference

[next hollow]

Also, just because that Set Damage Text is a float, doesn't mean it will magically work.
Whats that come from?
If thats coming from an int at any stretch of logic its "broken"

[past hull]

hello,
Do you know whats wrong with this logic to display a simple " Press F to pickup " when player is near a weapon ?
When player already have a weapon in his hands and try to pickup an other one, the widget is still stuck on the screen no mater where i move

[silver bough]

When i package my project i get this error saying its requesting 4 bytes when 0 remnain anyone help?

please

[rugged wigeon]

promote the widget to a variable and reference that. Don't reference data pins from other execution chains.

Node A should not use the data from pin B because it is made on the execution logic chain C

[past hull]

like this ? I have the same issue.
Sorry I am new to Unreal and Blueprints

I also tried to move the function on the child class because I have a PickupMaster ( Parent ) and a PickupWeapon

[rugged wigeon]

yes that is better

whats probably happening now is you're creating multiple Press F to pick up widgets. Your code is only going to delete the last one created. If you ever create a second before you delete the first due to stopping overlap, the first will be forgotten and never deleted

[past hull]

oh yeah I see I think this is the issue thank you

[mild jacinth]

hi

[jagged moss]

best way to learn niagara?

any advice?

[crude dew]

I do plan to scrap the idea of zillions of damage, It was more about finding out "why" I couldnt put that number into a Widget more than the "I must use it", After all knowledge is power and if I ever come into a situation or someone else asks me "Why cant I do this", I can then pass on the knowledge. 🙂, If that makes sense, Thank you to everyone for their input and explanations. 🙂

How to get the nav mesh to go till the bottom in this one

[maiden wadi]

This kind of depends. The main thing about GetAllActorsOfClass is that it allocates an array copy. For a lot of things it's really quick in most gameplay code. But when you start hitting thousands of things, you'll be paying for that.

[maiden wadi]

The why is both because computer numbers don't normally go that high, and because it's super annoying to see on screen. Outside of some amusing cinematic, nothing good comes out of having that large of numbers spewing about your screen.

[kindred galleon]

Trying to follow instructions from unreal engine docs(see image) on how to work with an Ik retargeter. So I created a new IK retargeter and opened it but It has no dialogue message popping up that says "Pick IK Rig to Copy animations from". I just get the IK retargeter window

[next hollow]

I know a game they does 20K, with no direct impact from the node itself.
Only when you suddenly deal 1 damage to 20k actors

[idle crescent]

Hey. What's the max limit of actors? I'm thinking of one without tick functions, in fact it's literally just a static mesh

[maiden wadi]

They are lying or don't understand how profiling works then. Because that node creates an array copy. It has a cost. Just depends on how much you deem acceptable for the ease of use tradeoff.

[idle crescent]

Just a plane

[smoky solstice]

Hey, I'm still really inexperienced with UE and this project that I'm working on (ignore the super ugly placeholder materials) has a bug where if I press dash it teleports me to who knows where and if I click escape, which I set up to close the game, it doesn't work. I found out that this only happens when I have this timeline to adjust my fov while the dash is happening is active so I can fix the bug by getting rid of the timeline that adjusts my fov but I'd like to keep the fov adjustment so does anyone have any ideas on how I can fix this?

[dawn gazelle]

Probably somewhere between 3 and about 2.1 billion.
The real answer is as many as your game can support on a specific hardware set up.

[idle crescent]

Mmmmm. I think I had an epiphany with making my own terrain system, just using planes and moving the corners based on things.

Perhaps that's an awful idea, and I will learn shortly after I try but it's a thought to me now.

Even tris, I know that's literally just how an engine works and all, but I could make it make holes so like you could do ditches and trenches and things.

[maiden wadi]

While I applaud anyone's desire not to use ALandscape and the default landscape solution. I would strongly recommend checking out the Cropout sample project for a showcase of the GeometryTools stuff and the DynamicMeshComponent.

[idle crescent]

First I'm hearing of Cropout

I'm thinking of runtime terrain deformation is why.

As one reason anyhow

[maiden wadi]

You might be able to do that with the dynamic mesh stuff. Though personally I would still lean towards trying out a voxel solution.

[idle crescent]

Eh. I was hoping Voxel Plugin 2 to happen soon, but that was a while ago.

I was thinking of making a Sims like game and it may work with the plane thing for terrain deformation at least.

[dawn gazelle]

I believe this is happening because you're launching your character with your velocity x 5 on effectively tick as the update path on a timeline executes like this. Instead, place the launch before the timeline play input.

Don't bother putting a delay within the timeline's update path either. You can use an "Event Track" in your timeline to trigger things to happen at certain times too.

[storm kestrel]

Hey ! How can I save player's resolution, player's statistics, etc ?
As you can see I already saved his audio

[smoky solstice]

So is this better?

[grave relic]

Anyone have an idea for this?

[fiery swallow]

It's not possible. AI have a maximum slope level they can walk up or down

I believe the default is like 50 or something, and the maximum doesn't even reach 90 degrees. That means it can't go up a straight wall for example

You can however make your own OR fork over $90 USD for the plugin someone created to allow AI to walk on any surface

[maiden wadi]

Try to make a single SaveGame with all of the options instead of a savegame per option.

[storm kestrel]

That's way better indeed, but how can I do that ?

[maiden wadi]

You've already made one. It's the same idea, except that you add more properties to it and don't make it audio specific.

[storm kestrel]

So I create a "load game from slot" function for each property ?

[maiden wadi]

The preferable thing would be to load and put the save somewhere global. GameInstance isn't a bad place in BP. Then your widgets can simply grab it and read from it. When a setting is changed/accepted, you savegame to slot, but keep the settings in gameinstance so that gameplay stuff that might also need it can use it.

[queen jacinth]

Hey y'all. I'm pretty new to game dev, I have a concept that I want to make a POC/MVP for, and I've hit a snag.

Long story short - I've got it so that I can change the player character's gravity, and the character will then move around properly, but I can't seem to change the perspective of the player (aka the camera) in the process. I've tried a few different things, but I'm running out of ideas. I'm almost certain I'm just missing something. Anyone have any insight? Feel free to DM if you'd rather.

[open garden]

When to use Blueprint Component (Actor Component) vs Blueprint Interface?
Obviously if you need to add functionality then you use BPC

But let's say you want to guarantee that an Actor has a Stats struct
You can add the Stats struct in the character blueprint then BPI_Stats implement the interface with a Get_Stats

Or I noticed you could just make a BPC_Stats with the Stat struct inside and then just attach it to the character blueprint
If you ever need to get the stats anywhere, you can easily use GetComponentByClass to get the BPC and its Stats

Both works, but I was wondering which is cleaner?

[hushed hinge]

I'm currently trying to build triggers that do " cinematic " actions in my levels. Like when a user completes an event it changes the camera over to something and does an action

Is there generally a best practice for structuring these things, should I be using a sequencer, should logic live on the level itself

If anybody has any good resources or guides on best practices regarding that stuff I'd love to see it

[hushed hinge]

I like to think about two separate concepts
Behavior
State
If it's important to me that something has some sort of state, generally in this case I would use a component.

If I'm expecting something to have some behavior then I will utilize an interface

For example if I want my player to have an inventory, I'm not going to have it implement some inventory interface per say, I'm going to use a component because that just makes more sense and then the inventory component could potentially implement a container interface that allows me to actually interact with the inventory in a standardized way

Now, let's say I have a bunch of props in my scene that the user can look at get some status text on the screen of what the item is, I might implement an interface that returns some examine text because to me that is a behavior of being examinable

[rotund barn]

this is basically working, all the time. but occasionally i get "accessed none...." error, which doesnt affect gameplay. the destroy is still working just fine. am i doing something wrong? or can i just ignore the error

[versed sun]

check to see if it is valid before deleting it

[open garden]

I understand, but let's talk more about your props in scene example

So you're saying you'll have an interface like BPI_Description that has a Get_Description function
Then your BP_Prop_01 implements BPI_Description and will implement Get_Description to return "Prop #1"
Makes sense so far, and this is actually what I would do as well

Now just as a hypothetical scenario
Let's say that we use blueprint components instead,
It's possible to have BPC_Description and have a string member variable Description
So then you would add BPC_Description to BP_Prop_01
If anywhere else wants to get BP_Prop_01's Description, all you need to do is Get Component by Class of the BPC to retrieve the BPC and then get the Description

Both should work, but I was wondering if the BPC is cleaner, since Description is cleanly stored inside BPC instead of BP_Prop_01

[rotund barn]

thank you, seems to have gone away now

[teal widget]

heyy, I have a UI that toggles visibility, though there's a bit of an issue with that when it toggles, nothing is hover tested until I click on the UI, and when I disable the UI after clicking the UI my keyboard controls for my player don't do anything until I click

[hushed hinge]

Yes but then you are stuck with only having a description

I specifically have an examinable interface
This allows me to determine what on each object's state I want to actually be the examined text, it doesn't have to be a simple description
It can be the object's name and stats, it can be the objects name and some sort of internal description, in contain additional state to actually render a widget instead that has additional information

I'm not directly tying behavior to state, I'm saying hey you need to implement this behavior and however you do that is fine

[primal crown]

what have i done to cause this xD
Draw debug string wont be visible

[primal crown]

that be nice

im on 5.3.2*

i kinda forgot cus i just usaly run the project xD

even just setting a cordinate in it dont work so its not the for loop

[keen tinsel]

i have an actorthat highlights when overlapping with character , using poste process volume , by enabling "infinite extent (unbound)" , but the issue is that this makes the highlighted actor show through walls , is there a way to acheive the same effect but without the see-through-walls ?

[smoky solstice]

I asked this earlier and someone gave a suggestion to put the launch character before the timeline play input and it didn't fix it but it helped a bit. Now instead of the fov change just throwing my character into outer space it just activates for a split second and then de-activates. This bug only happens on the first dash, after that no fov change happens at all. Any ideas on how I can fix this?

[tropic peak]

While spawning an actor, if I do this it should pass the variable value to the newly created actor?

[merry chasm]

Is there anybody here who use nanite + RT shadow + foliage with WPO? If I use nanite with ray traced shadow I got this weird shadow artifact 🥲🥲🥲

[storm kestrel]

I have a very basic question : I created a settings menu but right now it is in the middle of the game, how can I make it visible only when the button is pressed?

[keen tinsel]

disable the widget by default , and then enable it/show it on key press

[keen tinsel]

yes , sets a new value of the sapwned actor by the getter

[storm kestrel]

Thank you, where can I disable it by default ?

[tropic peak]

thanks, it was the sequence issue 🙂 I expected the item to set its name on spawn, but the variable wasn't set until after it was created

[keen tinsel]

infact , check your BP , u might have added the create widget + add to view port in the begin play somewhere

remove that and put the create widget +add to view port nodes on the key press :
1-"Button" on pressed -> create widget of class ->"promote it to a variable" ->add to view port
2-on released : get "your widget bp variable" Getter ->remove from parent

[storm kestrel]

Yes I have create widget + add to view point in the begin play of the level

[keen tinsel]

yeah , activate it through player controller

[storm kestrel]

but if I remove that from the begin play of the level, players won't be able to have music and SFX anymore no ?

[keen tinsel]

those settings are unrelated to the ui , u can activate them whenever , but the settings ui is what u r after

so u can modify the sfx and all through the ui

[storm kestrel]

so I can activate them in the game instance for example ?

[keen tinsel]

well , i dont know much about that , but i think u add those on the level blueprint

assuming theres music for main menu level , and different sfx for different levels

[ivory spoke]

Hey, actually I rework some functions and stuff (based on Items and Tool Interaction that I reworked for UObject Approach for Items)
Now I want to Rework/ Include this on my Harvestables (Stones, Ore, Trees) that can be Harvested by specific tools
At this moment I have Stone and Tree Actors and I think about to make an Harvestable Actor where I can choose its A Tree or A Stone (later other can be added)
Because the Logic within the actor is the same (only the loot and the tool needed will differ)
I hit it with specific tool, they lose live, if live is 0 they spawn loot (base functions)
On the Rebuild process of the Item Stuff, I liked to work with UObjects.
My Question is: does it make sense / is it legit to do it also with a UObjects (harvestable) where I can setup specific things (is it a Tree Level 1 or Tree Level 2 (do you need a more powerfull tool?)
What is the loot, what mesh does it have, how many life and so on...
The Actor Holding the Ubjects can respawn on Map (with persistence till they get harvested). Maybe someone has some thoughts on it :)?

[storm kestrel]

They are already in the level blueprint right now

I can send screenshots if you want

How do I change the player start location after run time in the Game Map BP?

[thin panther]

what's the game map bp?

And why do you need to change the location after the game starts, it's too late then

Also, read the #rules

Delete your crosspost

[keen tinsel]

yeah then link those sfx to ur game settings , so whenever a player wants to change something , they would activate the settings ui , and lower/mute ..etc the sounds

dunno how to do that , ima just leading u

[thin panther]

don't do music in the level bp

put your music anywhere else, like in the level itself

give it a sound mix, and apply a sound mix modifier.

Plenty of tutorials on the subject

[frosty heron]

Leading to a wall unfortunately. Level blueprint cannot be referenced by other bp classes. Hence do not use level blueprint

[rough wing]

Why do I need to test validity for this code? When I run as client it complains "accessed none" but still works

(error happens if I DONT test validity)

[dawn gazelle]

Because those errors means you're trying to do something when something isn't valid. The IsValid check prevents you from accessing a null pointer.

You're probably doing this on Begin Play of some replicated actor while "Running As Client" and this actor exists on both the server and client. As you're "running as client" that means you're launching a dedicated server which likely doesn't have the Enhanced Input Local Player Subsytem nor can it create widgets (it's meant to be headless, so no UI stuff).

[frosty heron]

Try to not use get player controller with index in multiplayer

If that's the character blueprint then just use get controller

Also seeing you are trying to add UI. Make sure to guard with is locally controlled so you don't make duplicate UI for every character in the world.

Beginner here, question about Attach Actor to Component. Is the attached actor supposed to follow the component around when it moves? Because when I move the plate after attaching the tuna the tuna stays where it was after I attached it (there is only one instance of plate and one instance of tuna at a time which is why I used Get Actor of Class)

[pastel apex]

what's the difference between elapsed seconds and triggered seconds?

[maiden wadi]

It should follow plate. Is the plate reference valid? Is anything detatching Tuna anywhere else? Is this logic actually being ran?

[smoky solstice]

I feel bad reposting my post over and over but I'm really stuck on this and I would appreciate any help ( again I'm really sorry about all the reposts, I've tried to leave large gaps between when I repost so people have time to respond but still )

[round elk]

hey, I suck, why doesnt this work

[mellow coyote]

Just checked if the plate reference is valid, apparently it is. I also did print string connected to the return value of attach to component and that came out as true. This must mean something is detaching the tuna somewhere else then? I cant imagine what could be doing that. I guess I'll do a deep look through my blueprints then

[maiden wadi]

Do you do any sort of SimulatePhysics calls or anything?

[maiden wadi]

Elapsed time is the time the input has been started and ongoing or triggered. Triggered time is only for time it's been triggered.

EG an input action that has been held for 2 seconds and has a 0.5 second hold timer before triggering would have a 2.0 second elapsed time and a 1.5 second triggered time.

[mellow coyote]

I used to but those are long gone

[pastel apex]

ah ok makes sense

so meaning on normal actions as soon as the input has been pressed it will count up until you let go

but for inputs with delay that's where they differ

[harsh comet]

Has anyone set up these level instance actors to be used with standard level streaming, rather than having to use World Partition?

[maiden wadi]

AttachActorToComponent will take the actor's RootComponent, the very top component in it's component list in the BP, and it wil attach that component to the parent component.

So your code there is taking Tuna's root scene component and attaching that to the Plate component.

If for any reason you simulate physics, detatch it etc it won't follow the plate anymore. Also to note. Your Root might still follow, but you could have detached a static mesh display of the Tuna from the root as well, which would cause the "Tuna Actor" to follow Plate, but note the static mesh component representing Tuna's visuals.

Either way though, attachment should definitely cause it to follow.

[maiden wadi]

Pretty much

[mellow coyote]

Thanks for the info, I think I figured it out. Pretty sure something is detaching it in my "pick up objects" code, I'm gonna rework it and see if it works any better

[mystic canopy]

@help
I'm using this code as a double jump in my game, it adds 700 velocity on the second jump to the players z access.
My problem is that if i double jump quickly it send the player flying up. I believe because the initial velocity is high at the beginning of the jump the second jump adds +700 on top of the original velocity. i just want the second jump to be the same as the first jump. is anyone able to help me?

[languid spear]

you could try using a clamp node to make sure velocity doesn’t exceed a certain amount

thankyou ill give that a go

Hello, hope you all are having a pleasant evening. I have a question hopefully someone knows the answer to and I'm just being dumb.

In the blue box I have a system to check for interactable actors within range of my player. In the other screenshot I have a demo of one of the base objects, (in this case, a key) with an editable text variable. With this line trace, is there any way to try and snag the information in that text variable so I can pass it in to my player character? I'm drawing a blank.

[tough frost]

how do i enable/disable a component in the child actors all at once?

[frosty heron]

What does enable and disable even do in this context?

[frosty heron]

I would just not use child actor component all together, they are known to break.

[tough frost]

what would you suggest?

[frosty heron]

For?

I don't know how your ladder is designed

If I have to do it I probably have sockets in the static meshes, these would be the point where the character can grab onto

[dark drum]

Actor component, you can create a child of the static mesh component (if it needs to have a visual aspect) and then add additional logic. In the latest first person template, epic do this for the gun and it's logic.

[tough frost]

hmm ill have a look at that template for referemce

How i can to attach actor which is simulating physics to my right hand socket, i wast trying to make attach actor to actor/component component to component but when this actor is simulating physics his mesh is not moving

[dark drum]

Whats you're end goal?

[hidden peak]

To attach enemies leg to my right hand to hide enemies body

[sacred birch]

I know some basics though

[dark drum]

It sounds like you might need to use physics handle component. This allows you to 'Grab' a physics actors and move it around while it still simulates physics. (in relation to the grab point)

[hidden peak]

I know this way but it looks kinda weirdo

I need exact to attach actors 1 thing to move him away

Wow gratz 🙂

[sacred birch]

Thank you but kinda difficult to crack interview due to no experience

[hidden peak]

Just say everything what you know

That`s the key to succes on interview i guess

[sacred birch]

That's why I wanted to know what type of questions can be asked

[hidden peak]

So do you know any other solution

[sacred birch]

But technical round is what seems difficult

[hidden peak]

Also one more issue with this solution is that only mesh is moving but capsule component is still staying there

[hidden peak]

I guess if you got selected you will handle it

[rose crest]

Hi. Is there a way to force rotation adjustment only 1 way? CW only not shortest route

[dark drum]

I would imagine this would depend on the company. Personally however, other than being able to modify default values in blueprints and place assets in the level I probably wouldn't expect them to know more than that as most of the design work would be done outside UE. After all, designing and implementing are very different parts of development. Granted the lines can get blurry, especially in smaller companies.

The job application would probably shed more light in terms of what the company would be expecting though.

hey i have a huge problem

i need to set every player controller a TEAM in LOBBY

then when i start the game on event begin play i need to get every team of every controller

how can i do that?

[rose crest]

its because shadows are based on normal mesh, nanite is skipped and you have miss alignment. theres vide on UE channel explaining this behaviour

[rose crest]

use player state

[spare sentinel]

i set variblae in player state? and on event bgein paly i can read every team from every controller?

you can access all playerstates array and loop for team variable to do whatever you want

What about nvrtx branch?

[rose crest]

I don't know if there's workaround

[spare sentinel]

andaron can you explain how can i do this? im nooby^^

[rose crest]

you're doing multiplayer, so you can use player state to keep information about individual players. then game state have access to all PS array and you can make function in game state to assign team or whatever you want.

because it should be game state (server) that decide who scored etc.

and inside multiplayer game player controller shouldn't contain any crucial information. its local only

(Context: turn-based multiplayer ability/action) when selecting an ability/action is it best to spawn a separate actor with collision and a decal for target previewing on the player controller for owning client and pass through a location/transform and class for the server to spawn effects/tags on targets etc.... or should the spawned actor be run on the server from the player controller and looped through by the server for actors of class to spawn effects/tags and show/hide the decal as appropriate...

TLDR - should spell previews be a seperate actor or not from the ability/action? (for extra clarity well maybe.... think the building preview before placing a building in an rts e.g spawn and just change material or have 2 actors one local for preview and one spawned on server for placement)

[spark steppe]

probably copy pasta

[rose crest]

I'd say SFX on client via multicast, results with rep/notif

and if it's actor spawned (skill) then server

now it depends of your gameplay, do you want other players to see preview?

it not then do it locally

[maiden wadi]

Are you C++ capable?

[odd kiln]

Is C++ better to save things ? Even if I made all my game in Blueprint ?

[woven pond]

@rose crest thank you, the skill part would be the effects/tags and will be on the server as for gameplay yes others to see but i was just thinking of multicasting within the Action/ability actor once placed to show the team a transparent version of the decal preview

confusion for me comes from having a decal for the preview/targeting and matching collision to this then doing it again later when activated for applying/spawning effects/tags to the same set of targets once activated

[spark steppe]

yes and no

[odd kiln]

Because I also want to make it "Aysnc" so I can use a "Loading Screen" and a "Saving..." text (UI)

[spark steppe]

better to save ✅
good for stuff made in BP ❌

it's not impossible, but it's a pita

[maiden wadi]

Sort of. It mostly has access to a specific function BP does not named Serialize.

I wrote these recently which I should also tag @dark drum for.
https://brandtborges.wixsite.com/authaer/post/saving-games-smartly
https://brandtborges.wixsite.com/authaer/post/uobject-serialize

[odd kiln]

So "Serialize" makes Saving easier and it's only available in C++ if I understand correctly, right ?

[maiden wadi]

Correct. To paraphrase what I wrote in those blog posts. It simply takes the desired data from a UObject. Which means any UObject, including Actors, and Components. And it writes their data to a generic byte array. And it also reads from a byte array and restores the data back to the objects.

It keeps you from creating specific structs and having to do a lot of upkeep.

[spark steppe]

downside of that is that it saves pretty much everything (which can bloat your save game size)

[odd kiln]

Why is it a bad thing to save everything ? I mean in which situation I would not like to save everything ?

[maiden wadi]

It does not save everything unless you specify for it to.

[spark steppe]

i think it would even serialize default values!?

[spark steppe]

ok, thought it would save anything but Transient uprops

[dark drum]

Only variables marked with the 'SaveGame' flag ticked from my understanding.

[maiden wadi]

You make an ArchiveProxy struct which you define yourself and you can tell it to only save SaveGame marked properties. Which you can mark in BP as well.

[odd kiln]

When you say "SaveGame" marked, you mean each variable in my Character Blueprint will have this "checkbox" that I should check/uncheck, or the whole Blueprint Actor has this checkbox ?

[maiden wadi]

SaveGame is third from the bottom.

[odd kiln]

What I clearly want to do is to save all of my variables of all of my actors in my game, and their positions etc...

So I will have to check this for all of my variables

[maiden wadi]

If you want to save everything, you can do that with specifying IsSaveGame in the archive proxy as false. This will save everything.

[odd kiln]

That I want to be saved

So in the end you recommend me to use the "Serialize" thing and save everything by default ?

Or is it better to check manually what I want to save ?

[spark steppe]

but what about things where you can't control it? as inherited variables

[maiden wadi]

The general idea with this is that you would save a struct of data relating to the object. Their Class, Name, Location(if they have one), and a TArray of uint8 as a byte array that saves everything else about them.

With the name, class and location, you can respawn them as the same class, at the same location. After you have spawned everything back in, you can run back over them and restore all the rest of their data.

[odd kiln]

Ok. I was just thinking about why it's not good to save "everything" by default

For example, all of my "walls" etc... that I don't need to "save"

[maiden wadi]

Depends on game size and how you structure the game. Saving everything can lead to some massive files sometimes. In other games saving everything doesn't mean much since it's only a few things.

[odd kiln]

It's a big open world game so I guess it's better to use this "SaveGame" flag

I just need to set some "TriggerBoxes" so when my Character overlaps them it saves his location etc..

[maiden wadi]

Still depends on how you structure the game. >95% of your open world is loaded from the map. You only need to save the dynamic stuff you spawn in, or affect on the default map and gameplay systems around it.

Consider a game like Skyrim. You enter a city. It unloads everything outside of the city. It doesn't exist at the moment except for some simulated stuff that doesn't exist in the world. You leave the city. You spawn stuff in around the city, but all the city stuff is unloaded and no longer exists except for simulated stuff.

You only save what is necessary to restart at that point. You won't save a massive map with hundreds of thousands of actors.

[odd kiln]

So now I don't know... is it really necessary to use the "Serialize" whereas I just need to save my Character variables and some actors variables ? Is it worth it to use C++ also ?

I mean I could make a "Struct" for my Character, and then a "Struct" for each actor that I want to be saved ?

Or one "Struct" for my Character, and one "Strcut" for all other actors ?

[paper yacht]

hey I'm spawning Bomb (Actor)
using simple logic. which is working perfect. but suddenly sometimes. Bomb getting destroyed within second.
First image spawning from PAWN
Second image Bomb complete blueprint.

it's weird problem. what can be reason of disappearing actors.
it's spawning correctly but sometimes it's instantly getting destroyed. without effects and all

[odd kiln]

So for example if I am in a "City" and I do some actions, I only need to save all the Actors in the "City", it's unnecessary to save again the whole game, right ? Or should I only save the Actor related to the action I just did ?

[maiden wadi]

Can't exactly answer that easily without knowing project structure. Cause if your city is all just simulated. And you drive that off of some property somewhere in like a primary actor or subsystem. And interaction with an NPC does stuff that doesn't require the NPC to be saved, then there's no point saving the NPC. Just restart it and update the sim time and reset the other stuff.

You won't find many guides on how to save a large world like that. It's far too complex of a topic and personal to the project.

But the serialize function at least gives you the ability to generically save the things you do choose to save and restore. No need for a lot of extra structs and conversion functions for each one around your save system.

[odd kiln]

Ok I understand I will investigate on this. I just don't know if I have to make only ONE "Struct" for all of my "Actors" except my "Character" or ONE "Struct" by "Actor"

[maiden wadi]

You mean to use the serialize stuff?

[odd kiln]

I don't know if it's worth it

And if I use the "Serialize" stuff it will save all the data with the flag "SaveGame" set to true so if I only want to save the "NPC_01" in the "City_01" it won't be possible

[maiden wadi]

You pick which actors to save yourself. the SaveGame marker is on the properties in the actor.

[odd kiln]

So even if I have 5 Actors in the City with the SaveGame marker set to true, after an action I can save only one of the 5 ?

[maiden wadi]

You don't mark the actors.

You mark properties on the actors.

[odd kiln]

Ok I understand. The good thing with the "Serialize" thing is that I wouldn't have to do a unique Struct by Actor

I guess

Because I have to name all of the variables in each Struct etc..

[maiden wadi]

Correct. It cuts out a massive portion of the dev complication and upkeep. Which also cuts out possible bugs and whatnot as well. For example if I wanted to save my PlayerCharacter, GameState, and GameMode. I would do something like this. In my system that takes in an array of objects of any kind and calls serialize on them to add them to an array of FSavedObjectData structs like I mentioned above with the Name, Class, Location, and TArray<uin8>.

[odd kiln]

Ok I guess I have to test it right now. I will look for a tutorial

[willow gate]

Hey folks. Random, general question to ask you:

Which BP do you generally play your level music on? In the past I have just put an audio actor in the level and used that but would best practice be to place it in the GameInstance maybe?

[odd kiln]

I don't find any tutorial of Serialize for saving game data.. do you have one maybe ?

Hey everybody, I have a quick question about categories that I have never been able to figure out. I am in UE5.1 using blueprints but some of the engine categories are showing before my custom category, is this fixable? I have a picture below showing the "Replication" category which is an engine category not custom appearing over my custom category called "my category". I know how to reorder categories that I made but I don't know how to do it when it's UE's categories

[harsh coral]

Quick question...in hindsight I think I may have made a mistake using a normal "blueprint actor" class for our modular character setup and I might have done better using the "charactor actor blueprint".
For example: I can´t simply add an animation track to the blueprint, when I add it to the sequencer, I either have to use the lead pose components skeletal mesh or add all skeletal meshes separately.
I also have issues with the lead pose component crashing unreal with Unreal 5.4 and I have to use a workaround now.
I was originally planning to add other stuff like light fixtures and backgrounds that I removed later on.
I still have a couple of empty actors I use to mass resize linked skeletal meshes.

Can anybody tell me wether its possible to change the blueprint class after creation or how I could salvage what I´ve already built (with dozens of variables and functions...)

?

[outer terrace]

ok.. this is really bothering me now.. anyone know how to save default locations for blueprint window? somehow my event graph and construction script tabs are default split screening with my viewport... even if i move them back up top .. when i close and reopen any blueprint it defaults to this location.. this is on a brand new computer with a new install of UE..

even if i save / load default layout it goes back to this.. and if i save a custom layout it still goes back to this.. so idk if theres a corrupt setting thats not loading .. but i'm not getting any errors on starting a project.. (launching from Rider)

[stable bane]

Hi! Can anyone tell me how to avoid this issue? Trying to add a random rotation to a selected static mesh from my array. Fairly inexperienced with Construction script. Any help appreciated :) Please tag @ me if you respond. Thanks! <3

[dark drum]

You array is an array of static mesh objects. These aren't spawned in the world. You'd need to either set the relative rotation of the static mesh component or the actor it's inside.

[stable bane]

Ah, that worked I believe. Though It seems I have a new issue. I want to add random rotation to my meshes but it simply wont work. Just doesnt do anything (no error or something). Any idea?

I am trying to make a custom gravity system where gravity can point in a random direction.

I am having trouble orienting the pawn towards the gravity direction while still allowing for player input to turn the pawn on its local Z axis.

I have this setup which sort of works but there's a ton of jank when gravity points in certain directions (1,0,0) and (0,1,0) and a moderate amount of jank otherwise 😄

Video 1: rotation with world up direction (0,0,1) (working as intended here)
Video 2: rotation with world up direction (1,0,0) (things are going wrong)
Video 3: rotation with random world up directions (kind of works but pretty janky)

are inherited interfaces broken? I have some BP code on a child class but my inherited interface isn't triggering it's event. I can see it as an inherited interface on the child class and I'm still calling it properly. Not sure what's up.

[white thicket]

add default slot in animation bp

[round elk]

um elaborate

[dark drum]

If the component is the root of the actor, use set actor location instead. (leave the target as self)

[dark drum]

If you use the interface in a child and still what the logic to call from the parent, you need to add a call to parent node. (right click on the event to find the option)

[dark drum]

The character movement component handles gravity direction to keep the capsule component upright. You'll need to update it to have the character orientated correctly.

Alternatively, if you set the characters movement mode to flying, you can rotate the character freely if you want to handle it yourself.

[narrow pendant]

I'm aware of cmc handling gravity direction however I'd like to replicate it with pawn class

so I guess the more general question would be, how do I orient a pawn in some direction while also allowing user input to further add to that orientation?

[round elk]

what

[white thicket]

in animation bp

just add default slot node

[round elk]

im using a montage

[dark drum]

Montages play on slots that you add to your animation BP. Without a slot, the montages have nothing to play on.

[abstract pine]

the data type of variable in event didn't match with the original. When Event being called, UE automatic change the data type.

The "Target " original suppose to be Object Ref type but when event ROS_Intereact being called UE change the data type of "Target" to Blueprint First Person Object Reference.

The data type didn't match with each others, I couldn't connect return value of "Get Overlapping Actor" function to ROS Interact because data type being change automatically from " Obj Ref" to " Blueprint First Person Object Reference"

How do I fix this ? thank you

The data type of Target in ROS_Interact suppose to be Object Referece no matter what ? It just change to "Blueprint First Person Object Reference" when being called

[grave relic]

Hey!
I have a system where I pick from the ground of life.
However, when I pick up life on the ground, my life bar only updates if I take damage.
Which means that if I am at 50 life points, I pick up life on the ground which gives me 20 life points, from that moment on, my life bar does not update.
I have to take damage to see the 20 extra health points displayed. For what?

I have two classes for characters. A parent class "BP_Character" and the child "BP_Hero".
The hit point system is in the parent class.
In the "BP_LifePickup" file which is the object on the ground, I do the following code:

[lunar sleet]

Show the code in the parent class

[spare sentinel]

im traveling from 1 map to another map

the ecent on swap player controllers doesnt start?

[lunar sleet]

Probably not what that event is for

Try OnPossess

[spare sentinel]

i want igve variable from lobbycontrolelr to gameplaycontroller?

[spare sentinel]

what i have to do to triger this event

[dawn gazelle]

• used to swap a viewport/connection's PlayerControllers when seamless traveling and the new GameMode's
• controller class is different than the previous

So seamlessly travel and have a different player controller class than the previous level

[lunar sleet]

Nvm it finally computed lol

Anyways when you open a new level you’re probably destroying one and spawning another not swapping, like Datura pointed out

[spare sentinel]

im seamles traveling from 1 map to antoher

with different controllers

the event doesnt fire

Did I do something wrong?

How do I keep this from overlapping with the box collision twice?

[versed sun]

Check the Component against something on the projectile

It fires on each component that collides, Mesh and Collision I'm guessing

You can turn the collision off on the projectile's Static Mesh

So basically my goal is to change the default gun in the fps template to a different gun instead of writing a whole lot of code and what not, so im going to change it to a pistol and i guess change the projectile as well. My only issue is the way the player will hold the gun, a pistol is way smaller than a ball launcher so is there a simple way to make the hand to a part of the gun using its skeleton???
it probably sounds lazy but its part of a challenge between me and a few of my classmates. Thank for any help, even telling me what to search on the web for would help as well.

[versed sun]

I believe there are free assets on the marketplace of Manny arms holding pistol animations

[vast flume]

so here is my issue, how do i impliment those assets?

[thin panther]

read the #rules as well. Crossposting is not allowed

thank you i will google a tutorial, whats the gist tho? am i replacing default animation? or am i calling on a animation when the gun is attatched to me

[versed sun]

You use a different animations that adjust your hands and fingers to look like you are holding a pistol, and firing , and reloading

[thin panther]

Makes sense! Discord can be a real pain sometimes lol

[vast flume]

do you know how to change the mesh of the default gun for the fps template

[thin panther]

Yeah, you can just go into it and swap the skeletal mesh for a new one.

It's going to be more complex than this though. As mentioned you'll need a new set of animations, in some cases have to adjust some IK, and make sure the animations you have fit the skeleton

[vast flume]

https://forums.unrealengine.com/t/how-do-i-swap-out-the-default-fps-gun-mesh-for-my-own-custom-imported-gun-mesh/633813

https://www.youtube.com/watch?v=Kys22RDQecU
same issue here, seems to be out of date as well

[thin panther]

You'll either need new animations, or target your mesh to the existing ones

For a pistol, you'll need new ones

[vast flume]

do you mind joining the vc, becuase I was able to replace the gun, but once i run over it and pick it up, it change back do the original BP even if I set to be hidden in game. Before pick it up, my model, after picking it up, old one!

[thin panther]

Unfortunately I don't do VC

check the gun's logic for picking up, it's probably spawning a different actor, would be my guess.

[keen kite]

Does anyone know how come actors are repeated in my array? I tried using the "add unique" array node, but it still sometimes prints repeated entries. I thought Array + CONTAINS + NOT boolean would keep repeated instances from being added.

[vast flume]

hmmm, where can i find the actor? so i can just force it to call my pistol mesh

[thin panther]

Find the actor that the pickup is, and you'll be able to find it's bp

[vast flume]

what do you mean? ive went and serch around for where it says which weapon to pick up

ive even tried changing the skelaton mesh to my piston but its till not working

[thin panther]

Notice how that pick up spawns a BP Weapon Component

Sure enough, if you open it, you see a skeletal mesh in there

And sure enough, changing the mesh there changes the pickup

However, again, if you want it to really work you're gonna have to have new arm animations, some weapon animations, and whatnot

[vast flume]

got it

do you think it might me smarter to just make a system for shooting projectiles and then adding a pistol anim?

[thin panther]

I would ask firstly if you need actual projectiles at all.

In any case, I would not piggyback off the first person template. It does things very unusually.

[vast flume]

hmm...

So, I have been trying for 2.5 days to figure this out. I have researched every "solution" I can think of. I have even ask 4 AIs too but the "solutions" they all gave. Did not work for me. I feel I am close but I am no longer sure how to fix it. I would be very grateful for your help.

What is Purpose/Goal of Ball???

-The ball launch forward (or backward if player desires) in the direction of the camera not the world axis.

Here is blueprint. Thank you. 🙂

[barren tangle]

it's not the camera

it's the pawn

are u sure that ur pawn rotate correctly and not just the camera?

if your camera rotate over your invisible pawn

the get forward vector will be on the same direction

reason why you are pushed back instead of forward

[barren tangle]

try something like that

[dense garnet]

O_O trying now..

Sorry, still kinda new at this. Only started in mid-May

[barren tangle]

we are all new 😄

[dense garnet]

I guess. I am new-er 😛 hahaha

[dense garnet]

wait I ahve a stupid question

Where do I plug this?

[barren tangle]

i guess into your add movement input

[dense garnet]

Did not work 😦

Still launches in the world direction/axis.. not the camera direction/axiws

[barren tangle]

?but you are into a dash function or in your movement function?

[barren tangle]

and if u try to multiply your impulse by ur forward vector

before adding it to the impulse?

[dense garnet]

Still no work. 😦 lol

[barren tangle]

no our old implementation

with the pawn

[dense garnet]

Oh... okay, I will try again

[barren tangle]

but you didn't answer me

what is the add movement input? it's the ball movement?

[dense garnet]

Hmm? What was your question, sorry?

Aahhh

[barren tangle]

or the camera movement attached to an invisible pawn?

[dense garnet]

"Add Movement Input" is a function/node.

I saw it in one of the "solutions" I reseaarched.

I am not entirely sure if it will help.

[barren tangle]

yes i know

i mean on which object are you using it

[dense garnet]

Did I answer your question? 😦

because it's attached to self

not camera

it's more clear now

[dense garnet]

-nods- sorry. I was not clear early

[dense garnet]

I can voice chat you

If you want

maybe easier for you? 🙂

I can share screen

brb quick pee

back

[barren tangle]

ok

ok lets go on live

[barren tangle]

still there

[dense garnet]

OH tyes... sorry...

Just had to talk to someone..

lol. .wait.. I'm trying to figure out how to call 😛

[dark drum]

This should be all you need to have the ball move in the direction of the camera.

If you want to ignore the pitch on the camera (so it only dashes along the x and y plane), you can do this.

@fiery swallow is there a way to chick if u are "in editor mode" :/?

[dense garnet]

O_O trying.. now..

[fiery swallow]

in blueprints by default? No, but there is this free godtier plugin that exposes the function to blueprints. if you download the plugin the functions name is "with edtor" and it returns a boolean

[steady night]

ah ok ill check it out thanks

Heya, I want to spawn Level Instances on a landscape. These Level Instances will consist of any amount of Actors. Is there an easy way to make all of the Level Instance nicely snap to the Landscape so the seperate Actors are not buried in it or are spawned in midair?

[maiden wadi]

Unsure how level instances manage their own actors, but if you could get all actors of the instance, you could project them with a simple line trace once the instance is finished loading.

[west crescent]

Yeah that's the only solution I have come up with so far. I don't know about Level Instances managing their Actors either so I'll have to look into that

Hello guys

I want to destroy the red actor, when the yellow actor (player) touches it

I've watched some tutorials, they all say cast the other actor (red obstacle) to the player class, then destroy it, like this, btw this is in the yellow actor blueprint (player)

[kind willow]

Your "Destroy actor" node is connected to the player, not he red thing

THis will destroy the player

[fallow gulch]

well, neither of them get destroyed

[kind willow]

Can you at least try destroyong the red actor first?

[fallow gulch]

I tried destroying both

[mental trellis]

Even if it was connected directly to the red thing, it will always only destroy a player because it has to pass a cast check.

[fallow gulch]

they both do have colliders, and generate overlap evebts

[fallow gulch]

I don't mind that, I just want to know why they don't get destroyed

[kind willow]

No? Cast check only checks for validity, you can put anything past it

[kind willow]

Can you try doing something else to the actor, like move it or change material? Just to make sure your cast works

[mental trellis]

The destroy node is gated by a cast check to his pawn class. So if it's not that class, the destroy node will never get called.

[fallow gulch]

let me try this

[kind willow]

Oh, yes, that's true, but I hoped URoni would know what class to cast to, so it wouldn't matter

[fallow gulch]

yeah same, it just went through the red actor

[kind willow]

No change?

Can you check the collisions settings?

And make sure overlap events are enabled

[fallow gulch]

they are, the yellow player has block all collision preset, and the red one has overlap all dynamics

[kind willow]

player is a pawn type, not dynamic, unless I missunderstood?

[fallow gulch]

player is a pawn, yes

[kind willow]

Also, you can try adding a break to the "Begin actoroverlap" to make sure it triggers

Right click > Add break node

It will add a red octagon on the node

When it triggers, the game will pause to let you know

[fallow gulch]

i got it working

[iron idol]

https://medal.tv/games/unreal-engine/clips/ikepuGEit13KCKJ2f/d1337YXMsdaa?invite=cr-MSxydHcsMTUyMTMxNzQ4LA

anyone have an idea as to why I'm starting offset from my player start?

[kind willow]

It will try to move you to a side if there's something in the way. Are you sure there's nothing colliding there?

[fallow gulch]

From the beginning, I wanted to destroy players, as I want this to be something like an endless runner game.
All I had to do, is change the player's collision preset from block all, to overlap all

Looks like blockall preset never triggers overlap

[iron idol]

This is a good theory. I think the only thing i could be colliding with is the ball actor. I don't think so, but I iwll check

[steady night]

hey im having issues with the Ai move to some of my Npc is getting the resault "aborted" need tips on how to trubbleshoot why its getting aborted if anyone knows ??

the same npc Bps 4 works 2 dosent so its not related to Conditions or anything it must be something more specific maybe in the cmc or something ??

[fallow gulch]

Go to game mode, and change default pawn class to your player's class

[iron idol]

It is

[fallow gulch]

Try making a new game mode base

[barren tangle]

hi i don't understand what Curve Id is

[bold phoenix]

Hello everyone, I'm trying the cropout UE sample project as a base for another project. However there seems to be a problem with the overlaping... Inside the function, the "hello" string is shown in the log but no the two other ones. Even though the legth of the array is always greater than 1 when it is being called. Any idea if this is just a log printting issue or if this just cannot work ?

[remote marten]

Hello I have a small question : I want to bring a data asset definition file into a blueprint and parse its content. What should be the type set to for this to work ?

thank you

it is sitting on a spline bp

[barren tangle]

why do we have a set timeline lenght if we cant add a key??

[verbal kayak]

how to pan a material to right? I dont want it to animate. Just adjust.

[gusty dragon]

with displacement in 5.4 how do I make footprints in the ground? is it possible

[steady night]

anyone got tips on how to debugg AI ??

[spark steppe]

like everything else

watch the BT execute, set breakpoints in custom tasks, etc..

[steady night]

well the problem is its just instantly aborting the command

i cant really trubble shoot >:>

[barren tangle]

is there a way to know the surface of a box collision

[maiden wadi]

What do you mean by surface?

[barren tangle]

the minimun point thar let me know what are overlapping the box

because i would like to know what is inside my box.

and i can"t use the overlap event

because i need to find the instanced static mesh inside of it

and instanced static mesh doesn't work with overlap, so i need to know exactly where i need to search for those meshes.

[maiden wadi]

This is where I'm confused though. What does this have to do with the surface? Your end goal is to get the ISMs within a box collision?

[barren tangle]

i need the coordinate of that box collision

[lament nebula]

huh... funny, i came in here wanting to ask basically the same question-ish x3

[maiden wadi]

Is it all one component, or multiple ISM components?

[barren tangle]

grass is one, but i can have multiple ISM inside of the box

[maiden wadi]

Cause ISMs are represented by their instances. You'd need an array of ints basically and a reference to the ISMComponent.

[barren tangle]

yes

[maiden wadi]

So To start you'd need a struct that has an array of ints. And you'd make a TMap out of that with ISMComponent/StructWithArrayOfInts.

[maiden wadi]

Then there is.... Sec

[barren tangle]

i have all there istance number

and i link each instance to a transform? and after i check which instance is inside my box?

so i guess i take the get actor world location + ??? + ??? to know the surface where i need to check, the limite transform where i need to check

[maiden wadi]

Something like this, maybe. Then you can associate each array of instances with it's component in the map.

[barren tangle]

sounds good

i will try into that direction

[lament nebula]

So might be related, im trying to make a construction method that subdivides the bounds of an actor (for visualization’s sake its adding box components) now i want to remove all the subdivision nodes that are not overlapping with the mesh, i tried using the get overlapping components on the boxcomponents (the mesh and box should be children of the same parent) but that gives 0 results.
Any ideas how to tackle it next?

[dark drum]

As an FYI, if you plan to remove any instances, this will mess up all the indexes you might have stored somewhere.

[dark drum]

What's your end goal? Why are you needing to subdivide the bounds?

[lament nebula]

i guess im trying to get a kind of bastardized octree representation of a mesh so i can hang a bunch of params on the nodes to eventually add other functions to so i make stuff happen more detailed on a mesh rather than happen on the entire mesh at once, if that makes sense?

or maybe even better, if i made a fire system with it, i want it to propagate slowly over the mesh, but players have influence on what parts are wet or already burned for example

could prob apply it to somekind of creeping goo too

[dark drum]

So what I would do is create an array of box variables. (The structure that was shown above for something else) This take a center and the box extent.

You would start from the bounds center and extent and check if it's overlapping anything. If it is, remove the entry from the array and add 8 new ones to replace it where the center and extent is updated accordingly. Repeat on all entries that overlap until you reach some defined limit. (4 subdivisions for example)

[lament nebula]

yeah, but the problem im currently having is that im not getting any results on the overlap checks

[barren tangle]

is there a condition to the overlap?? like 100% into the box?

[barren tangle]

the grass is the only actor / components that is not found

[versed sun]

Something like this ?

[lament nebula]

you did that quick... but yes

I went around it sort of similar 😛

[rotund barn]

how do arrays work in blueprints? ive used them in programming, but like lets say i have a boolean array, will it basically only store 1s and 0s (true and false), or does the variable im using to set an index in it, matter somehow? to simplify my question, is there ANY other bits of stuff/information in a BP array other than just index and the values. sorry if this is a dumb question.

[lament nebula]

what are your graph spline settings btw?

[lament nebula]

Just like a regular array, collection of indices and values of whatever type you instantiate them with

[rotund barn]

oh okay, thanks

[versed sun]

Default Electric Nodes Plugin

[dark drum]

Are you after something like this?

[lament nebula]

yeah, but i think i have it figured out now

[dark drum]

The octree is just stored as box variables.

[rotund barn]

would there be a difference in using these two? should i opt for the non-cast one when possible?

[frosty heron]

There is a clear difference, mesh exist in Character level but you will not be able to access ThirdPersonCharacter member variable without casting.
Say you have hit point variable that is declared in ThirdPersonCharacter, you can't reach it without casting when the object you are trying to pull it againts is not the type you are after.

[maiden wadi]

I don't know what language you're used to. But there's no difference from BP arrays than most other language's array. It's just a list of a type of data.

[frosty heron]

GetPlayerCharacter will return Character reference

[rotund barn]

thanks

[rotund barn]

okay, thanks. so basically in this specific case, where i just need the mesh reference, i dont need to cast. but if i need a variable from thirdpersoncharacter blueprint, ill need to cast, right?

[frosty heron]

Yeah and when you are casting, try to go as generic as possible

lets say third person character have more child like bp_Goblin or bp_Archer

but you just need to access member variables in thirdpersoncharacter

then you just cast to thirdpersoncharacter

[rotund barn]

oh okay, thank you. i always try to google everything first but i usually get stuff completely unrelated to my search. i need to improve my googling abilities

[frosty heron]

asking questions like that are perfectly fine

you will get quick answer most of the time

[dark drum]

Just in case you want an alternative method.

[iron idol]

Is it possible to make an actor have no collision with the player but can still be detected by sphere trace?

[frosty heron]

Look up collision channels

[lament nebula]

thanks!

[lament nebula]

hmmm i had hoped it would catch some more detail, but this seems to just be htting the simple collision

[dark drum]

You can set the collision on the mesh to use complex but that might not be ideal. The only other thing to do is make custom collision for the mesh that better conforms to the shape.

[lament nebula]

where can i find that setting?

[dark drum]

double click the static mesh in the asset browser

[lament nebula]

oh, i see it

[barren tangle]

i have my grass (ISM) inside the box. but the overlapping actor doesn't found it

how can i check if the grass is really there?

[fringe junco]

hmm so Im trying to build a utility AI but Im having an issue wherein the score variable seems to be global for a single category of uobjects ie the uobject behaves like a singleton. Is there an alternate way to structure this? or what datatype should I use instead of a uobject?

[faint forge]

How I jump in AnimBp to the code "behind" this node?

[steady night]

im trying to reduce world scale from 100% to 0,25 over the timeline duration

what am i doing wrong

[thin panther]

you're lerping from the current to the desired value which is ever changing

every time that lerp is called you're lerping between different values

[steady night]

oh ofc

should be a fixed value

or ? hmm

[thin panther]

yes it should

I.e. cache that scale ina variable before the lerp is called

So in this case, before the timeline plays

[steady night]

but shouldent this work really ?

[thin panther]

It would, but that breaks if the object is not at scale 1

[steady night]

well it is

but its not working hmm

hm its not changing

not changing the values at all

i must be missing something O,o

ah okey i was lerping normals....

[lament nebula]

I am clearly missing things here, but i feel the complexity is already getting out of hand, can anyone help me brainstorm on this fire system and point out any bears on the road?

• game start
• collect all flammable objects in the level into an array
• divide all objects into a grid of nodes that can catch on fire
• if a node on an object is on fire, the nodes send events within a radius based on details
• nodes that can burn will constantly be listening for the event, take damage, catch fire, become event emitters

One issue i see is that i think the CPU wil catch fire with 100000's of events screaming every step (to be determined, not every simulation step)

[faint pasture]

how many nodes we talking about?

[lament nebula]

im not sure yet, but optimistic estimates are probably about 400k-600k "nodes"

[faint pasture]

uh yeah, that's 100% C++ territory

[lament nebula]

well yeah, but more trying to figure out if this is the right path

[faint pasture]

It can work. What's the goal, simulating fire propegation in 3d?

[lament nebula]

yeah

[faint pasture]

are the nodes all the same size and spacing? Like, is it basically just a 3d voxel grid of On Fire / Not On Fire?

[lament nebula]

thats the current plan yeah
