It's in there, the properties. GameMode is where you say that pawn, controller, hud, etc to use.
You wouldn't believe what I've seen people do, and of course, what is source control?
balmy apex

The pawn is where I set the correct player class thing?
faint pasture
The pawn is where I set the correct player class thing?
Yes the default pawn, that's what'll be created for the player
balmy apex
Yes the default pawn, that's what'll be created for the player
Thanks! Now I just need to figure out how to move that each time the level is reset via the death screen.

That's easy. It's just an actor. Just move it. Although are you restarting the level or restarting the player?
Because if you are restarting the level then you need to store it somewhere else.
balmy apex

This is what the DeathScreen does, so I think it's a level restart?
faint pasture
@balmy apex yeah don't do that, unless that's what you want to do.
But then you would need to store where the player should spawn at in some thing that survives opening a level. That would be your game instance or using save files
For a test, try using restart player instead
There might be some other functions you can mess with too, I haven't done much with restarting games because my project literally doesn't do that ever
balmy apex
<@193091961773621248> yeah don't do that, unless that's what you want to do.
All I want to be able to do is open the DeathScreen upon death, click a button, start the level again but with a relocated spawn point.
It doesn't really matter to me how it's done, just that it works
faint pasture
All I want to be able to do is open the DeathScreen upon death, click a button, ...
Try use restart player instead. It'll take you 10 seconds to test it.
balmy apex
Try use restart player instead. It'll take you 10 seconds to test it.
In the DeathScreen event graph?
faint pasture
You can figure it out
balmy apex
Well, guess it's not in the DeathScreen since searching it didn't show anything
Wait, I already have a Restart Player in the character event graph
faint pasture
Restart player is a function on the game mode, so you need to first get the game mode to do it
balmy apex
It's also in there
So I guess it's working since it's in both places
And the respawn system does work, it just keeps respawning at the same place instead of moving like I want it to
balmy apex

This works, but how do I move the start location?
faint pasture
This works, but how do I move the start location?
The Playerstart is an actor. You can set an actors location.
balmy apex
The Playerstart is an actor. You can set an actors location.
Right, is that also in the GameMode? I can't figure out what nodes I need in the blueprint to get that
faint pasture

Get the Playerstart, then move it.
Get actor of class will get you going
balmy apex
Get actor of class will get you going
That's probably what I needed
faint pasture
And do all of this where you're handling the rest of the death logic. GameMode would be best, do it all before calling restart player.
balmy apex
This is what I have now, and it's the same as before
This doesn't make it so the PlayerStart moves, I must've done something wrong, I'm just not sure what
balmy apex
And do all of this where you're handling the rest of the death logic. GameMode w...
This is what my character blueprint looks like too, if that helps
dawn gazelle
This is what I have now, and it's the same as before
That's because you're setting the actor that this code is in to -50 on X. You need to plug the playerstart into the target of the SetActorLocation node.
balmy apex
That's because you're setting the actor that this code is in to -50 on X. You n...
How do I make this Movable?
It's all grey
That doesn't have a "Movable" option on it
It's just a basic PlayerStart, and I don't know enough C++ to change anything
In a normal game, yes, but that's part of what I'm doing
I want the player to be spawning closer and closer to an island that I have until they don't die anymore.
junior hedge
how exactly do binds work
do they just run constantly?
ik how to use them, just wondering
balmy apex
I still don't know how to do this. It sounds simple enough, but I'm clueless
This is what I have right now, and it thinks I'm trying to move the PlayerStart
Listing functions and saying to override them isn't helpful since I don't even know what half of those functions even are
manic knot
I’ve triple checked, when I print out the Hit Actor it it is the correct Character, could it be because I’m setting it to a Local variable first? Could it be that I’m using a function and not an event to do the trace? I am invoking the function from the Server

devout geyser
Anyone knows the reason why widget button event on clicked works on 2nd click? and not the 1st one?
the blueprint is pretty simple
event clicked -> remove from parent - self(the widget)
tawdry surge
Pry didn't set your focus so thats what the first click is doing
devout geyser
@tawdry surge you mean like this? still the same result
tawdry surge
Try "set user focus"
devout geyser
Nuh still the same... I am trying doing with custom events and such but nuh chief nothing works. Its so odd
tawdry surge
Yeah thats the only reason I'm aware of that it would make you click twice on the first button push
devout geyser
The method works on different widget tho, with the same logic like press button -> widget gone | and it works fine
balmy apex

All I really need is to move the player spawn on the X-axis, but nothing seems to actually do that. Even this just keeps throwing an error at me about not finding something
limber parcel
i dont see anything that would affect the player spawn in this code
balmy apex
That was supposed to be the goal of the Offset
limber parcel
tawdry surge
You can't set the actor location of the player start cuz it's not movable. You can spawn a new at the new location and destroy the original
But id Google the functions mentioned above and make a custom system thats a lil more scalable
balmy apex
I don't need tons of scale, I just want to move the player -50 on the X-axis every time they respawn
devout geyser
@tawdry surge fixed it, I am an idiot

maybe u cant modify player in same tick its created
devout geyser
so basically without noticing i called the event that is creating the widget twice without noiticing in the player's BP, sry for stressing ya
balmy apex
maybe u cant modify player in same tick its created
I didn't know that's what the blueprints were doing
limber parcel
i cant say for sure but this system tends to do weird stuff like this
i was messing with foreach loops the other day and apparently delays just stop the loop
tawdry surge
Then make a transform variable on the gamemode
Bind on destroyed with the player character as the target
Then on begin play also get the player start transform
Then off the delegate you can unpossess the character update the location, spawn a new one and possess it
balmy apex
I got as far as creating a Transform variable, and now I'm lost. I'm fairly new to UE, so I need a lot of direction
tawdry surge
Type in " assign on destroyed " in the game mode event graph
That will make the binding and delegate event
balmy apex
Ok, got it
limber parcel
anyone got a good tutorial that covers delegates? i never actually used them in blueprints lol
tawdry surge
Feed in the player character as the target for the bind
Then you just need to, from the delegate event, "unpossess"-> add your offset to the transform and use it for the spawn transform of the new one-> "spawn actor from class"->" possess"
You use dispatchers? @limber parcel
balmy apex
Feed in the player character as the target for the bind
Then you just need to, f...
This looks good so far?
tawdry surge
Basically it assigns an event that will be fired when ever a dispatcher call is made from the target
balmy apex
Umm, Unpossess doesn't show up for either of them
faint pasture
@balmy apex if you can't move PlayerStart just make your own movable actor to use as the player start and move it. Or do it all with logic in the GameMode. You're making this way too complicated.
balmy apex
<@193091961773621248> if you can't move PlayerStart just make your own movable a...
I couldn't figure out how to do the former, and the logic part confuses me
tawdry surge
They're setting it up in the game mode now
balmy apex
Get Player Controller doesn't show up anywhere either
faint pasture
Just make sure you understand what's going on. All a PlayerStart is is an actor that the GameMode looks for when choosing where to spawn a player in at. You can make it look for other actors or just override whatever functions in GameMode you need to to make spawning work however you want.
balmy apex
I tried to make it just the player, but that didn't work
tawdry surge
Get player controller isn't showing up as an option in the gamemode event graph?
balmy apex
Not if it needs to be connected to something
tawdry surge
No it's a pure node
balmy apex
I can get it just fine by right clicking
balmy apex
So now I have 2 things that reference Player Index 0
tawdry surge
It gets a lil more complicated if it's multi-player
But single player it'll work fine
tawdry surge
So left part we're gonna run off a custom event
Right part will run off dead
balmy apex
So the right part will do this stuff?
tawdry surge
Nah begin play only runs once so after you die 1 time it won't respawn you again
balmy apex
Oh, so how do I get the player to "die" then?
tawdry surge
We'll bind on destroyed to the new pawn from the on possess event in the controller. Thats later tho
For now just attach a custom event to the code on the left side of the first picture
Then attach "dead" to the code on the right
balmy apex
tawdry surge
Oh no
viscid barn
you might want to update the controller to possess another pawn otherwise wouldn't you just end up stuck?
tawdry surge
Custom event->bind on destroyed
Dead->unpossess
We're gonna get there
But you can't possess a new thing without unpossessing the old one first
balmy apex
Ah, I reversed the right side
viscid barn
But you can't possess a new thing without unpossessing the old one first
I meant after, yes
balmy apex
This is better
balmy apex
Oh, like this?
tawdry surge
Yep
Now we want to take the spawn point transform variable you set and we want to get it
So pull that out from "my blueprint tab" on the left
We then want to right click the orange output pin and "split struct pin"
This will give you the location, rotation, and scale individually
Then you're going to pull off the location pin and make an add node (vector + vector on ue4)
This is where you add your offset
Then you need to set the spawn transform variable to save this new transform.
Make sure you plug in the original rotation and scale values if you want to keep them
balmy apex
What kind of variable should Transform be? It's a Vector for me
balmy apex
tawdry surge
Get -> Add->Set
balmy apex
Huh? Get what?
tawdry surge
If you grab the transform variable from the tab on the lower left and drag it onto the event graph it will ask you get or set
You want to use a get first then we will add to it, then you can set it to the new value
balmy apex
So, Get Transform, then do the addition, then set it?
tawdry surge
Yep
balmy apex
It won't let me connect Transform to the addition
balmy apex
balmy apex
balmy apex
Ok, got that
tawdry surge
You can right click any colored pin on the right half of the set node to recombine the struct btw
balmy apex
tawdry surge
Yep
balmy apex
The only part here I'm unsure of is the class I chose
I chose the actual character instead of the playerstart
tawdry surge
What class is your default pawn set to in the gamemode
balmy apex
The class I chose
balmy apex
Ok, awesome
tawdry surge
Now you can pull off the player controller again and possess
Then use the output from the spawn node as the target
balmy apex
Where does the possess go?
I'm just seeing "Add Possessable" from the SpawnActor thing
Is it like this?
tawdry surge
Yep
Now all you gotta do is hop over to the controller BP so you can call your custom event in the upper left and switch the binding target to the new pawn after each death
balmy apex
Controller BP?
faint pasture
Why TF are you guys doing all this stuff, way overdoing it
balmy apex
Hmm, I have a controller for my main menu, but I don't know if I have one for my actual level
balmy apex
Why TF are you guys doing all this stuff, way overdoing it
I don't know any other way to do it
tawdry surge
What is the controller attached to the game mode
You're almost done
Just finish this way
balmy apex
I see Get Player Controller in the game mode, but that's it
tawdry surge
No in the class defaults what player controller class are you using?
slender sky
Anybody here willing to share their advice or experience working with PrimaryDataAsset in blueprint?
Any known quirks or possible pitfalls?
One of our projects got corrupted after changing some PrimaryDataAsset related stuffs.
The whole project wouldn't open anymore at this point, keeps crashing even before the editor is ready.
Got no choice but to rollback to a previous backup.
tawdry surge
3rd one down
balmy apex
3rd one down
Yeah, I'm just not sure where that is outside of right there
tawdry surge
Its the default so it's a c++ class in engine content.
Were just gonna do it from the player class
On begin play in the player cast to the gamemode class you are using
tawdry surge
Nah you want a reference to the object not just the class
Just a cast to MainGameMode
balmy apex
So this one?
balmy apex
To the left of the cast?
tawdry surge
Yeah
When casting we need to have an object we are try to change the reference type of
balmy apex
That makes sense
tawdry surge
Last step is to call your custom event from the "as main game mode" pin
balmy apex
Uhh, I don't think it's moving anywhere. Should I be using something other than the PlayerStart in the editor?
I changed the Transform value in X and it didn't do anything
tawdry surge
Well 50 is a little less then 2 feet
Maybe test it with a much bigger number
And you mean the x value of the add node right?
Changing the variable default value won't do anything
balmy apex
I changed it to 1000 and it was still in the same place
tawdry surge
On the add node?
balmy apex
Yeah
tawdry surge
And when you die you are respawning?
balmy apex
After I click the button to respawn, yeah
tawdry surge
Then something isn't right.
You shouldn't need to do anything to respawn. It should just happen as soon as you die
balmy apex
I made a button to respawn
tawdry surge
Oh then you'll have to do some break points and a print string to see whats happening
The thing we did should do it automatically
balmy apex
This is what the button press does
slender sky
I'm not sure how you 2 end up with such a long thread, can't you just do the following instead?
- add 1 vector variable to track the player's spawn position, put it somewhere persistent (game mode, game instance, level, player controller, etc)
- add the extra distance (+=) to the vector at the start of the player pawn spawn (actor/character beginplay)
- SetActorLocation to that value afterwards.
tawdry surge
No that destroys the game mode too so your transform is reset every time..
You'll have to test it by actually killing the player
Jump off the edge of the map or something
balmy apex
The player dies after being underwater for long enough, the death screen shows up when they die
This is what brings up the death screen
tawdry surge
Ok.. do you then call destroy actor on it
balmy apex
No, the screenshots show all the code I have for calling up the death screen. Should destroy actor go after the Set at the end?
tawdry surge
Well you'll want to delay so the player can see your death screen but yeah
balmy apex
This is the death screen right now, the player is supposed to click the button to respawn
tawdry surge
Then you'll have to destroy the character from the button press
balmy apex
Before reopening the level or should I just remove the Open Level entirely?
I don't think I can destroy the character from the button press, that doesn't seem to show up anywhere in the death screen event graph
tawdry surge
Remove it entirely
And you'll need to "get player pawn" again and call destroy actor off that
balmy apex
After destroy actor?
tawdry surge
Yeah
balmy apex
Is that it then?
tawdry surge
Should be
balmy apex
Something still isn't right
tawdry surge
Looks like you're spawning in the landscape and falling through
You'll have to play with your offset
balmy apex
It's only -50
tawdry surge
In the game mode you're setting the transform to the player start transform on begin play right?
Otherwise you're snapping to -50,0,0
balmy apex
This is the whole game mode
tawdry surge
On beginplay->set "transform location"
You wanna then get the player start location to feed into the left side of the set node
tawdry surge
No make a new set node
You want to set the value in the beginning so that every time the player dies you can update it
balmy apex
How do I get the player start location to link to the set transform?
I don't remember which thing is the player start location
tawdry surge
"Find player start"
balmy apex
That doesn't go into Set apparently
tawdry surge
No just right click in space
tawdry surge
You need to connect the controller reference to the player pin
And then pull off the return value pin and type get transform
balmy apex
This doesn't feel right
tawdry surge
It will work
balmy apex
tawdry surge
The proper way was overriding the built in functions but this way is fine for your purposes
Yeah go ahead and test it now
balmy apex
And overriding doesn't make sense to me anyway
"Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetPlayerPawn_ReturnValue". Node: Assign On Destroyed Graph: EventGraph Function: Execute Ubergraph Main Game Mode Blueprint: MainGameMode"
It breaks after clicking respawn twice
vernal mountain
How do I record the output string as well as index value for the Random node? Since each print string calls it and gives two different values
tawdry surge
Ok.. click on the custom event node and in the details panel add an input
balmy apex
Who is that to?
tawdry surge
You
balmy apex
Ok, got it
tawdry surge
Set the type to the class of your character
balmy apex
balmy apex
I see one, yeah
tawdry surge
Plug that into the target for the bind node
balmy apex
faint pasture
You guys still plugging away at this?
tawdry surge
Yeah
Last thing.
Pop into the character BP and plug a self ref into the custom event function call
balmy apex
balmy apex
It keeps dropping me in the same spot again. And after the mouse is used once, the cursor stays on screen
tawdry surge
If you put the mouse on the screen then you gotta take it off again
And you'll have to print out the location values to see what is happening with that
balmy apex
What do you mean by take it off again? I had that already set up somewhere, I guess it's not working for some reason?
I don't know how to do that.
tawdry surge
Idk where you set it up, but nothing we just did would effect that
balmy apex
It was probably in the death screen when the level was reset.
I don't know how to hide it again though
tawdry surge
Get player controller->Set show mouse cursor to false
You'll want to do that in the death screen before removing it from parent
balmy apex
Like this?
tawdry surge
Yeah
balmy apex
Now to get the transform of the spawn working, somehow
tawdry surge
Your best bet is to use print strings and check what the values are while playing
balmy apex
How do I do that? I've seen it done, but never how to do it
tawdry surge
Type print string and plug whatever you want into the in string pin. Most things will auto convert
There's also an append node for putting a bunch of values on the screen at once
balmy apex
Well, it works now, so -50 was just probably too low to notice
I really appreciate all your help. Your patience is immeasurable my dude. Thank you so very much
tawdry surge
Nice glad it finally works
balmy apex
I have 1 more thing to figure out, but that can wait until I have a couple tries. It's just setting up a "win" condition which shouldn't be too bad
balmy apex
Hmm, whenever I add something, the death screen no longer goes away
The mouse cursor disappears as expected, but the death screen stays
Fixed it by saving the level again

I'm used to reactive programming in ReactJS so this is a very basic, fundamental question about programming in Unreal - let's say I have a boolean and if it's true I show one mesh, and if it's false I show another, is that something that I program in the "Event tick", so it's checking the boolean on every frame, or is there a way to program it so it only checks if the value of the boolean changed, like React would do it?

So let's say I add a button to the UI and when I click it, it triggers some onClick event where I change the boolean from true to false. Do I also program the mesh switching in there as well? Or can the logic for switching the model be somewhere separately, so it only reacts to the boolean changing its value?
tawdry surge
It can be wherever you like but generally you want to let things handle their own logic.
So if the mesh is gonna change then I'd put the switching code in the actor with the mesh

Are there any build in ways to create time-independent spring animations like this one? Set the stiffness to 0.05 to see the effect better. Sequencer uses keyframes so that wouldn't work and I found TweenMaker but that's also time dependent.

So the loop error is probably coming from the fact that in one frame you could infinitely be failing that branch statement
Resulting in it calling
If it fails, then it never has a chance to change, so it calls again, and fails, and calls again
trim matrix
it could, but it shoudnt. Since with a .1 delay it works fine
since its end in user input at some point
should I just add a tiny delay to fix it? or?
thin panther
No you need to restructure that, cause im not seeing where user input can interrupt this loop

this is the turn order bit that it calls

astral stratus
yeah im trying to figure out a better way to do it..
desert juniper
yeah im trying to figure out a better way to do it..
get rid of
you're multiplying it by 0 and then adding it to another vector
a vector is just 3 float values
so you're adding 0 to all three valies
astral stratus
yeah so thats what i had a feeling because the guy has a boom arm on his third person char and i dont
desert juniper
giving you an original value of the vector to begin with
ah so if you're in first person, indeed multiply it by 0
but if you're in third, multiply it by the boom arm length
astral stratus
im in first
desert juniper
that way you'll get a line trace from the character onwards
astral stratus
so i should keep it right?
desert juniper
it's just muddying up the code
astral stratus
i had a feeling

everything else is right

how can i do that?
mint mica
https://gyazo.com/dd232e29c52e3fe52f593c013660e6cd
there is a function called "find look at rotation" which would give you a rotation value that you can use to make the ghost object always face you as you spine around
object location as the start player character as the target then you'll need to tweak the values a bit

I assume you're having a tough time because you can't decide between a static mesh and a skeletal mesh
if all you're working with is a static mesh, then just add that to the parent BP, and don't actually add a mesh
let the children set the mesh

@desert juniper
I've tried that, but I don't see it in my drop down. I've tried typing in the search in numerous ways to see if I can get it to come up, but no luck. Could it be a difference in the character movement component? It looks like the first person blueprint had some changes between the tutorial build and now.
desert juniper
maybe it's deprecated in ue5
void yarrow
Yeah seems possible
desert juniper
don't see it in the docs for UE5, only for 4.27 and below
void yarrow
I was hoping to reproduce the node via the GetMaxSpeedModifier, but that doesn't appear to exist either.
desert juniper
looking at source code, there doesn't seem to be a max speed modifier valiable
desert juniper
I'm assuming it's just a multiplier. why not do it yourself?
create a wrapper, or just save the modifier on the character BP
slender sky
desert juniper
then just set the max speed to be maxspeed+maxspeed*multiplier)
void yarrow
Thanks for looking for me. If anyone has any idea how to reproduce that setup in UE5, let me know.
I'm very new to blueprints and UE programming.
slender sky
Sounds like it's deprecated?
void yarrow
Do you know what I would be multiplying?
desert juniper
uh, i just kinda explained it

😄
void yarrow
Thank you!
slender sky
"GetModifiedMaxSpeed() is deprecated, use GetMaxSpeed() instead"
desert juniper
which is odd, since it's not what the previous function was doing
void yarrow
Yeah I tried that and it doesn't seem to work. Could be an error elsewhere in my BP.
desert juniper
kinda odd that they'd deprecate it from the movement component, but it'd be super easy to add that in yourself

(using getmaxspeed)

just creating a wrapper component

If you are making the assets you can just export them from your dcc with the pivot point at the bottom.

Hi, how can i create a child from MaterialInstanceDynamic ? I don't see it
MaterialInstanceDynamic is not an asset type that you create in the content browser, then you create a dynamic instance of that material using the Create Dynamic Material Instance node. The Transient folder shows that the object was created at runtime and will be destroyed when the game ends. I am not familiar with that bit of Lyra so you'd need to see what's creating that instance and see if there is a mechanism for setting your own material as the base class for your instance.

Anyone know any decent tutorials on how to create a save system? I've looked at so many but can't figure it out lol.
tawdry surge
You're not gonna find many good full system tutorials. You're better off just learning the basics and building out the system you need incrementally

Ah, okay, thank you.

hello, anyone can help me in private for a simple problem I have?
your reference to RefV2 is null
how are you acquiring a reference?
molten stone
like this
tawdry surge
Assuming the third person character owns the widget you could just pass the ref v2 in on spawn too
bold torrent
GetText is a bound function to a TextProperty I assume. It's most likely the case that your reference is being called first frame when widget is created, during which the Reference has not been fully initialized (Which would be the second frame).
Easiest way to get rid of the error is to just check if the variable is valid before reading anything from it @molten stone

You can store refs in your widget
So what I am trying to do is create a UI that shows the distance between a radio and transmitters in the level. The transmitters can be turned off and on so the UI will have a dynamic list. I watched a tutorial about server browsers so I can learn how to make the UI with dynamic slots for each transmitter. My problem is getting the actor location for the transmitters so I can display the distance in the UI. Could this be done using your method?

Is there a reason why BeginPlay() would be called after GetSpawnActor in this screenshot?
those first two UE_LOGs were written in the GetSpawnActor() and the second two logs were written in BeginPlay()

Yeah, use a map or array, if a transmitter* pops up, send a message to the player saying 'this transmitter* popped up' then it will send a message to your hud, that would be 'add this transmitter* to the map' the hud will check every frame through each map 'value array' element the distance and update it on the hud, depending on the corresponding 'key array' value

Does anyone know of a way to swim up on waves, that are displaced by the material, using the default water provided by unreal?

Right. BP BeginPlay is not actually C++ BeginPlay. So the Parent Call node you have there mainly calls the BP Parent BeginPlay, not the C++ one.
The BP one is called in the Super::BeginPlay method as a BlueprintImplementableEvent
So it's basically redundant to call the parent node in BPs if the BP is a direct child of a CPP class
Super::BeginPlay will cause the BP code to run and then it runs whatever comes after that in c++

can you help me with how to configure it?
devout grove
@surreal peak is there a way to get the C++ code to run before the blueprint?
surreal peak
Theoretically by placing it before the Super call
But you have to keep in mind that you then lose whatever the CPP parent of your CPP class did in BeginPlay
If you need to ensure this, expose your own BlueprintImplementableEvent
And call it after your BeginPlay code executed
And use that in BPs instead of BeginPlay

@trim matrix do you have BlueprintReadOnly set for the UPROPERTY() macro?
devout grove
any chance you didnt instantiate it in the constructor?
maybe swap it over to BlueprintReadWrite?
trim matrix
I Instantitate it in BeginPlay, is that the problem?
But even if BeginPlay comes way later than the UWidget Update.. it should still work...
devout grove
i usually instantiate components in the constructor. If i have to do any dynamic bindings, thats in the PostinitializeComponents()
id say swap it over to the constructor and see if that helps?
trim matrix
Also, the bug is sporadic.. when I disconnect any node on that BP Widget and connect it again it works
Yea ok, I will try
Does not work in the constructor.. the widget is not even getting created .. propably because of GetWorld() which is not available in the constructor??

I was wondering if someone could lead me down the right path here. Im needing help for a TurnBased Battle game that Implements Action Command timed prompts inside of battle.

Nothing is available in the constructor, except static assets.
And you shouldn't use them in constructors.
trim matrix
Yea, I figured
devout grove
we're only talking about instantiating components right? woudnt you want to do that in the constructor?
like if i want to add a spring arm or a camera, you instantiate them in the constructor like in that screenshot right? Same thing for components right?
im fairly new to this so im probably wrong but this usually works for me
trim matrix
@devout grove sorry, I think what Daekesh ment was something like GetWorld(). My bad though, I confused it with the Widget... yea I do instantiate the health component in the constructor
Also set it to BlueprintReadWrite.. still getting sporadic errors.. it is really frustrating tbh xD
This is clearly a bug and I need a work around
devout grove
i think i might be wrong about changing it to BlueprintReadWrite, should probably be left at BlueprintReadOnly altho i dont think that will fix the core issue here

😦
@trim matrix i guess my last question is what blueprint are you working in? Is it for a UI widget or is it on the player blueprint itself?
can you check if its currently registering as a nullptr when you look at it?
im wondering if its just not getting initialized or was never set
trim matrix
Its a WidgetBlueprint. I think there is no solution for this. May be due to Live Coding? The problem exists since 2016
Recompiling the Widget Blueprint solves it
Still.. really annoying
devout grove
those issues are the worst
trim matrix
Indeed
Maybe there is a way to write a python script to recompile specific blueprints when compiling the project
But I am not annoyed enough to look into it right now

Hey, you here?
I got a very weird situation here
you meant it like that, right?
but if I do that, I get true way more often than 30% of the time.
worn verge
Can you show us the random bool with weight function?
weary lodge
My goal is that if I click on the botton it has a 30% chance going to to false
weary lodge

Ye
weary lodge
it should work in theory, right?
paper galleon
That probably works fine. You just need a large enough sample (number of times the function is called) to accurately determine if it is truly 30%
E.g you can't test only two times or even ten times and expect a good result.
weary lodge
Are you sure it opens the right level?
30% of the time it needs to open ROOM_SUDAN_0_END1

Okay, how do make a bigger sample size?

paper galleon

You'd have to click the button a LOT of times and record which levels are open. But that is not necessary. The function is probably working properly
weary lodge
but like
i opened the lvl like 5 times and it was the wrong lvl 5/5 times
that seems to be very wrong
paper galleon
The "true" level opened? Or th false
versed sun
Instead of opening the level (which takes time), just print if it is true or false
paper galleon
Again that is the nature of randomness. If you opened the level like 50 times, the false would probably open more than the true
weary lodge

30% of the time it needs to open ROOM_SUDAN_0_END1

Hmm. You could implement your own random bool function if you don't trust the provided one

are you ".3" or ",3" ?

I have a dodge mechanic in a game that if you're standing still, should dodge you forward. I have it working whenever the player is moving, but I can't seem to get this standing still working. Can anyone enlighten me as to why this doesn't take the player's rotation, make it an angle, and point the vector (5000,0,400) down the player's X world rotation?
(What happens is it dodges in the world X)

"bro" I dont know how to code.
trim matrix
run the code 100 times, then print how many times its false or true
opening a level 5 times and then complaining its not random enough doesnt make sense at all
worn verge
I'll quickly ask something
Does anyone know why this code does not work when my character dies?
Setting the visibility of a WBP does not work anymore.
This is basically the code
And I use a selector to know which visibility setting to choose.

@worn verge code stops working when your player dies? if the pawn gets deleted then the controller no longer has an owner
i think
does the controller possess something new after the player dies?

Can i make something like an unconventional custom LOD in blueprints? Like a group LOD, not a LOD for one but more characters.
For example, if im at 0.01 zoom, I replace 1000 people by a cube with textures on each side.
How do i do this?
versed sun
Have your zoom code trigger LOD changing Event Dispatchers
Then in whatever holds your 1000 people, bind something to the Event dispatcher
cyan bone
Have your zoom code trigger LOD changing Event Dispatchers
So in the zoom input you mean?
Everytime i zoom in i check if the actors Groups of Warriors are far
versed sun
yes, where ever you change Spring arm Target Length, or move your camera
cyan bone
Ok, but wont checking it for all groups of soldiers be too expensive?
Is it possible to check only for those that are on camera
maybe this is just making it worse
Its just that there are blocks of armies that are very far away, and it wouldnt make a difference to convert them to boxes with textures
so they are still visible, but they are now just 1 thingie
this vs 50 impostor instanced static meshes per batallion
or maybe im just overthinking
versed sun
are the groups each an actor ?
versed sun
ok
cyan bone
But they get huge
versed sun
is it a top down view, mousewheel zooms ?
cyan bone
wouldnt it be benefitial to convert the whole group into a cube at a far away distance?
versed sun
ok
so i would start, every time the view changes, either zoom or panning, call an event dispatcher
in your Group actor, bind an event for that dispatcher
worn verge

It does not. It did work in my previous project. I'm just simply remaking it.
It shall work
versed sun
that event you just do distance from camera to self
cyan bone
thats brilliant
versed sun
if it is over/under threshold only then do make a change
cyan bone
and this is better than having the little soldiers replaced by impostor sprites, right? Because this means 1 rectangle cube with textures vs 100 sprite impostors?
cyan bone
pls tell me
versed sun
use a scene cap component, take a "pic" of the group, and display that material on the cube
so, if you have a non full Group, like half are dead, your far LOD can show that
