thorny cedar
i want to have it like an icon on the ground, when the player gaze on it i want a menue to appear
earnest tangle
I mean if you want it to move with the player but not with the camera, then attaching it to the pawn but some other component should work just fine
Ie. say you have Root -> Camera, attach it to Root
thorny cedar
so to the default scen rout of my pawn?
thorny cedar
ok will try it, but i think i tested it
@earnest tangle i think i want it attached to the camera, but not in the z axis
thorny cedar
so that i can always moven down my view and look at the icon
i also do always forget the axis naming
earnest tangle
yeah so if you attach it to the scene root, it would follow and rotate with the pawn
the camera is the one that gets rotated up and down
so it should function as you wanted
thorny cedar
it should always be in focus, so it has to be attached the camera, but not during th normal view
up and down axis yeah

I still get into macros under some circumstances, even if I clicked "step to next"
I don't use macros in general and would rather not see the insides of all or standard macros when debugging...
in the example, there is one break point for the entire project and it opens a macro for me after it (probably because the end of the loop)

When I want to add a "Child Actor Component" inside an actor.
I can only access its variables with the "Spawn Actor From Class" node, wen I mark them as "Expose on Spawn".
Can I set the variables of the child actor before they get created, so they can be used in the "OnConstruction" node?
lucid hemlock
why can I only catch the first time???
@frank heron you need to re-enable collision on release on the object
nocturne remnant
@astral fiber it returns the component so you need to get the child actor and cast it
astral fiber
@nocturne remnant I have set up a simple logic inside the child actor. Based on a boolean the material is ether green or blue.
Now I want to set this value inside the parent actor
I have exposed the variable so you can set it when you use the SpawnActor From Class node. But I dont know how to do the same with an ActorComponent
nocturne remnant
take the return pin from your add child actor component and do get child actor
astral fiber
yes, then I can set variables and call functions, but at this time the child actor is already constructed and rendered.
How can I change the variables so it has an effect while running the construction sequence
Is it possible to spawn an actor inside an actor, or can there only actorCOmponents be created?
nocturne remnant
oh, now I understand what's happening... because of the construction script... I apparently missed that. You could do a SpawnActor and then attach it
astral fiber
Thats what I am trying at the momen, but the Actor seems to not get spawned inside the actor
I am not sure if I can use this node inside an actor
@nocturne remnant Seems like you cannot use the SpawnActor Node inside the construction script, it works when used with the Event BeginPlay..
So I can only work with components. I just cannot set variables before construction
nocturne remnant
it'd be really bad if you could spawn stuff in the construction script since that would happen when doing stuff in the editor
thorny cedar
i want my sphere attached to my camera, but not dependend on the up and down of my camera :/
having problems finding the right way to do it
rotation up and down
independent of Pitch
nocturne remnant
why aren't you just attaching it to the root component?
elfin hazel
Seems easier to attach the sphere to the camera and use World as rotation method instead of local.
nocturne remnant
so this is a VR camera?
thorny cedar
jap
elfin hazel
hm, so you don't want to inherit pitch rotation, what about the other axes?
thorny cedar
@elfin hazel my end result is a sphere on the ground that is moving with the player camera, but not in the Pitch axis of the camera. it shall inheriot the yaw of the camera
roll is not important
elfin hazel
Oh them I'm not sure. Attaching a scene to your camera and having absolute rotation would make it follow the camera location but ignore the rotation all together. can't really prototype atm

Hi everyone,
I need help on something I'm trying to do on UE4 with blueprints, unfortunately I didn't find any help online for it but I'm sure it's not that complicated to do. ^^
Here is the situation:
On my PlayerPawn, I have a CardManager class. In this class, I have declared a TArray<TSubclassOf<AActor>> named Cards.
I've filled this TArray on Editor with Cards wich are Blueprint classes. Each Card has a C++ CardComponent with all the variables needed like CardName, CardCost, CardDescription etc....
What I want to achieve is to access CardComponent variables of a Card randomly picked in this TArray.
For now, I've succeed by using Spawn Actor to the card randomly picked before accessing its CardComponent variables.
But I want to know how to access those variables without using SpawnActor, because for example if I want to find a specific card in my deck with a specific name I have to Spawn all the Card Actors first.
I hope I've been clear, if not, feel free to ask questions.
If anyone has an idea please help me! :D
Thanks!

Hi! I'm using set actor hidden in game to hide this actor on overlap, but the hidden actor stills has collision. How do I hide it and remove the collision?
graceful trench
@molten ridge So when you're idle and rotate, the camera doesn't rotate with it?
molten ridge
it rotates but the character doesnt move with the camera
like the character doesnt turn
but when running it does
graceful trench
Ahh, that's because the Character is a Parent to the Camera. So it will not obey the child's rotation. you'll have to somehow tell the Character to obey the child's rotation when you're idle.

I'm attempting to recreate a common data structure in BP but I'm missing something. I'd like to store a list of markers that belong to a player. So I have a map of Int->Struct and the Struct has a single property that is an Array. Currently only the first marker is added to the array. Subsequent attempts to modify that array are not working, as if I'm modifying a copy instead of by reference. Anyone know the step I'm missing?
I've also tried setting the modified array back onto the struct, and also tried re-adding the struct to the Map

I'm currently in the process of refactoring existing blueprint code... at the moment, that mostly just means moving it from one actor's graph to another.
Is there any good way of copying variables and graphs, and placing them in new actors? I can copy/paste some things, which definitely helps, but not everything can be copied, so it's a tedious and possibly error-prone process. I've googled around, and though I have found some useful stuff for cleaning things up... none of it is what I'm looking for.
In code, it's not too hard to just copy/paste everything, including function and variable definitions. Maybe I could copy the entire blueprint, but this is a situation where I have some code which I threw into the character class, and in retrospect, it should have been put in the controller instead... just making a copy of the character isn't an option.

Can I make a movement like this? like it's a 2D in 3D world, where I click left or right & jump or drop down, like if I have a path & the character walk that path no matter what direction it faces, with only go forward & go backward!

While trying to make a health bar, this happens when health is updated. Any ideas on why?
This is the blueprint I'm using
This too, in WBP_HUD

maybe cause it didn't find it? but why?
I think this could be fixed if you made a "?is valid" node & link it to the target!
& if it isn't valid AKA the character or whatever then print "why it isn't valid" to fix it later, cause I think you should be sure that it ask the health to be change only in case it's valid!
Place it before the node that asks the target for anything!

@mellow stump truncate the floats first. then to string
truncate rounds to the nearest whole number and provides and integer that you can put to a string.
mellow stump
Wow, that worked right away, your a lifesaver
stiff hatch
glad I could help
if you dont want it rounding to the nearest then use either floor to round down or ceil to round up
mellow stump
This should work great, should be a unique seed for every location i need to generate content at. I was worried if i multiplied or added the X Y and Z's that there would be repititions elswhere, others that would add up to the same number/seed. This should do nicely tho π

mellow stump
In the past ive ran custom events into the same node a key press goes into, both execution lines went in

You might want to come up with some kind of data structure for this

Correct
So i'd have to create a datastructure, and assign different texts to the variables?
oof

if you don't have a large amount of dialog I guess you could get away doing it some other way too

Your E event isn't talking to anything

its rotate a handle and then window itself

flat raft
Can I suggest a better workflow?
your E should be on your player controller, or player character
nocturne remnant
Yeah, that's not at all the way you want to do that
flat raft
The problem is you won't know which window the E event is talking to.

Also, don't use a specific keyboard event. Make an input in your project settings, bind that to whatever key you want, and then use that input event

can't do that. I'm doing this assets for marketplace and interactive things is the one of the features. so i can't rely on if user set "action" button in project

i have a general question about saving, anyone on that can maybe help?
see, i have enemies that are spawned into the game, i have a save and load system for the player but have not set one up for enemies. what i would like to do is, save save locations of enemies that have spawned in to respawn when the game laods instead of starting over again
nocturne remnant
So then you have it start with a custom event that an input can call. You definitely don't want random stuff accepting inputs
mellow stump
That BP is your window, yes?
charred vale
ye
mellow stump
The boolean has to be on each window
charred vale
it is
mellow stump
player over lap window, cast to window and use Other Actor as ogject of Cast, set boolean to true
reverse for end overlap
flat raft
If you want to have it work this way, then your Handle and your Window need to know who it's coming from... like Self.. Bp_Window.Handle
ya, gotta cast

cast to character to see if action key has been pressed, after a box collision with character
nvm

@fossil dagger create an array of the location of all the spawned enemies. Save that array with your same game. When you load, spawn your enemies class at those locations

So what specifically is the problem with saving that?

@fossil dagger use a loop and collect the world locations into an array

@fossil dagger an array of ur enemy
nocturne remnant
Transform. That way you get the rotation too

with break or nah?

flat raft
Pull off the box
trim matrix
pull off the box and type is overlapping
see what option u have
actually just pull off the box and type is overlapping actor
it will say target is component
then u can link the other to ur player character
@fossil dagger Use forloop
you can add each actor to an array
flat raft
Sweet!
fossil dagger
for each loop or just for loop
flat raft
For each
charred vale
it's kinda strange, i watched many tuts for beginners about such stuff, but no one ever used or mentioned "is overlapping actor" node

This yeilds no string to print

@remote meteor I managed to fix it... i was spawing actor from class instead of ai from class lmao

i think you need to manage it yourself, but can you use the "Switch Authority" macro node in ABP probably you can do something from there
not very sure but afaik, an actor can differentiate itself whether its local or remote version using this node
that could also work
that checks for a pawn's controller whether if its a local controller
authority checks if the actor belongs to which client

Why does my incrementation is twice here ?
It's a weapon switch loop, the index should be incremented once each time I press a key.

its faster to do it this way i guess

A timeline runs for the length of time that it's set for and outputs the value on the curve at a particular time.

@nocturne remnant I could understand that much, I guess this translates to rotate 180 degrees every 1 second then ?
I was trying to figure out if it was connected to tick...
either way I noticed a massive performance boost using that instead of event tick

I've heard timelines run on their own "ticker" instead of the game's tick

Isn't this redundant code since the Ammo variable already is replicated? https://gyazo.com/de616687d3d4f829f186d99114518038 ? It's from a marketplace package so I'm not sure why this is here?
swift quiver
@rare ember Not necessarily. The event is to replicate the change of setting the ammo across the server to the clients, even though the variable is replicated
Im fairly certain thats how it works at least

Hey all, I've been going at this particular task for a while now, and even after taking a break I am unsure of how to do it. I am creating an electricity system(?) which requires a Source, and a Conductor to work. If the source is powered on, anything that conducts electricity will be able to carry the electricity to the next conductor, and the next, and the next, etc. I am currently doing it in Tick, because I don't think overlap events are suitable for the way this will work.
The problem is that the first conductor is able to carry the electricity through just fine, and maybe the one after - but if you get rid of the conductor connecting to the source, the rest still hold the electricity instead of having no electricity.
Here is a clip of the problem:
https://gfycat.com/dangerouseminentgoa
I have tried many different methods to get it to work:

(none of them do)
Here is the current method:

hollow tree
hey all! i'm fairly new to UE in general and i'm currently trying to detect when a beat happens in a song given a time stamp, i'm getting the current playback time of the audio clip, and when it reaches a certain value(1.600023) i want to reset it to 0 so i can do the same with the next beat, but once it reaches the first time, it gets stuck on 0 and the value doesn't update anymore :(
i'm sure it's something to do with the last SET
static charm
whats it running from? tick?
hollow tree
i believe so yeah, it's parent is an OnAudioPlaybackPercent event
dawn glacier
maybe you have to play the audio again or set it to Loop
hollow tree
the problem is not that the audio stops, since the bpm is 147 it's supposed to print a single "BEAT" once the playback time reaches the first bar (1.60023)
frank heron
Why is this
pastel ibex
@static charm thanks for the video suggestions, but they weren't really what i was looking for (they were much more advanced than i need anyways), so I'm still stuck with this issue
swift quiver
@hollow tree If you are only setting the current playback time variable to 0 at the end, then it will stay at 0 until you set it somewhere else
hollow tree
ohh i see!
static charm
@pastel ibex i see in your code, you need to set electricity to off when there's no source conductor
hollow tree
ohh i think i ended up solving it lol, i added a new variable to keep track of the total sum of beats
static charm
you have it set to on when true, but when false, there's no setting it back off
pastel ibex
@static charm yup, but i've tried many methods to do it, all of which dont really work.
i think it might be because they are one class, and they run the same bp to each other too
so theyre kinda self sustaining lol
pastel ibex
where would I implement that?
pastel ibex
yeah lol
right now i have a visual check using a debug line, but it will be even worse of a problem with particles, since there'll be 2 of each for only one connection
so i'm at a loss as to how to do this correctly
nocturne remnant
Holy shit. You made cold fusion with chairs. Except for that one that flew off into orbit; I'm sure that won't cause any problems.
pastel ibex
lmao, exactly what i thought
i did a nice ctrl+Z and I (hopefully) averted that problem
i dont get why this is so hard to make dammit
static charm
all this should need is just a way to turn off that it's connected to source
and then turn off electricity when it's not connected to source
pastel ibex
yup
thats the problem though, nothing works as intended
if i tell it to stop conducting electricity at the second branch, new conductors after the second one wont connect
i've also tried ways of finding out which actor was the one connected to the source, and then seeing if its valid, etc, but it all resulted in the same problem
static charm
so a check after the loop if blueprint already has electricity set on
or after source check
Does the connected thing have source power, yes. do i have power yes, then do nothing. Does the connected thing have power, yes, do I have power, no. then turn power on. Does the connected thing have power, no. Do I have electric on? yes, then turn off.
static charm
yeah i might have missed something in my thought of it but generally should work after a bit of trial and error
pastel ibex
yeah, i'll report back soon
static charm
hmm you'll still have the recursion issue i think. ill keep thinking for a little bit
pastel ibex
yeah, thats the biggest worry
pastel ibex
yeah, i cant get it to work with what you suggested either, damn

This may be gibberish, is it possible to set a datatype to any datatable that inherits from a specific struct?
sand shore
What problem are you trying to solve there
remote meteor
inheritance in structs, unfortunately no i think
sand shore
Oh yeah, definitely not
BP doesn't really do struct inheritance whatsoever because passing around parent references end up slicing the object every time
twilit heath
doesn't even let you slice
sand shore
Well that's true, but if it did let you get to that point, it'd slice
twilit heath
i had 2 FTablerowBase structs, same parent, nothing added to them, just different defaults

trim matrix
So, i'm trying to create this chain.
the sissue is just the fact taht im pretty sure an update fucked it
Man, i cannot spell
So, according to the example, im supposed to be able to set target to Player Character
But, im unable
twilit heath
your screenshots are too low res to read
trim matrix
Ah, discord compression
mb
this better?
So thats how im supposed to be able to set target.
Though im not sure exactly why Interaction Interface doesnt posess it.
twilit heath
how would an interface Possess?
twilit heath
unless you're swapping pawns thats dont exactly once per match
trim matrix
I'm not sure why im not able to assign it a Player Character
twilit heath
your message log complains about accessed None when that code runs then
what was None?
trim matrix
twilit heath
that also doesn't mean anything without knowing which blueprint it is (does it derive from Pawn)
im guessing not
remote meteor
that is an interface
twilit heath
your message log tells you exactly where it broke, i suggest you read it
remote meteor
not related to type of class
trim matrix
your message log tells you exactly where it broke, i suggest you read it
@twilit heath Thats not exactly the issue
I don't have a target output from my Event Interact.
Lemme go check it
remote meteor
its an input to be exact
twilit heath
which means you didn't connect the pin or pushed a nullptr in it when you called it
your interface function has to have a Pawn input for that to work, too
trim matrix
Ic
twilit heath
(it can be anything that derives from Pawn)

Hi guys!
I got stuck on a weird thing. A SphereTraceForObjects works in the parent class (returns True), but for some reason fails in child classes (always returns False).
Am I missing some common knowledge there?
Child classes are data-only, I do not override anything etc.
remote meteor
you can check from the draw debug is it drawing a proper radius?
trim matrix
I mean, shouldnt this be sufficient?
I'm creating a dialogue system
incase you get confused
twilit heath
that is a bad way to detect interactable objects
twilit heath
its way simpler to create a CollisionObjectType for interactables
paper python
That is weird. Yeah, the radius was not as expected, for some reason! I replaced the variable with a hard-coded numerical value, and it changed things (and traces well now).
Thank you!
remote meteor
twilit heath
and then just overlap with/trace for that object type
remote meteor
trim matrix
That is weird. Yeah, the radius was not as expected, for some reason! I replaced the variable with a hard-coded numerical value, and it changed things (and traces well now).
Thank you!
@paper python It does use that though
remote meteor
this should be suffice
trim matrix
This is to toggle the ability to start a dialogue with the object.
remote meteor
@paper python make sure the variables on the child is set properly on the defaults though
paper python
@remote meteor I have assumed that if I never use that variable anywhere else, the child would inherit it with same value as in parent?
twilit heath
it does
paper python
That is the kind of wisdom that takes a bunch of pitfalls to obtain π Thank you!
remote meteor
life with unreal engine blueprint
twilit heath
blueprints have their fair share of serialization fails, but you usually need c++ involved to break them
remote meteor
yeah it wouldnt really break normally
trim matrix
I mean this should succeed in setting the interactable as target, right?
Im really not sure what i'm doing wrong, im new as hell to this
And yes, its inneficient, but its not like im running a resource heavy game.
remote meteor
that snippets is
when Interact button is pressed, i will find the first item in the array and call its interact interface
twilit heath
@trim matrix its code inefficient
trim matrix
@trim matrix its code inefficient

which means you need more of it, and that gives you more room to introduce bugs
oblique ruin
@remote meteor @sand shore i have a bunch of data tables for a multiplayer game Im working on that each contains particular character data. Those in turn are inside another data struct. I just wanted to know if there was a way to set variable to only accept datatables to only accept ones that use are particular type of struct, just as sort of security thing so I dont accidentally get a bunch of errors.
trim matrix
Im not asking for a simplification really.
twilit heath
doesn't matter for performance at this point
remote meteor
hm
i dont think theres such thing, you have manually control what comes out of the Get Data Table Row node
twilit heath
your interact function doesn't have a Pawn input tho
remote meteor
i only could think of composite data table if any chance you are talking about combining data tables, but this requires the exact same struct
@trim matrix check your interface
you need inputs
oblique ruin
Yeah that sounds kinda like what I was looking for
sand shore
It might seem that simplification is a pointless tangent, but I would have to agree with Zlo.
Any case, have you done any debugging? Print String nodes would be your safest bet but you could attempt to use the debugger itself
twilit heath
i'd go for a data asset holding references to all the DTs and returning you the correct one @oblique ruin
that way your other assets only need to reference the data asset, not 50 different datatables
oblique ruin
For data assets you need to do that in c++ correct?
twilit heath
i am not sure that you do, as you can derive a BP from c++ UDataAsset, then create a DataAsset from the BP class
oblique ruin
So I could set it to only accept a particular data asset type? Is that kinda what your saying?
twilit heath
yeah, and your data asset would be the only thing referencing the datatables
with get functions returning you the one you need
twilit heath
you enter datatable references just once that way
oblique ruin
Hmmm okay that makes sense
trim matrix
that was wayyy simpler than i thought
twilit heath
even if you can't make a BP data asset directly, you can get away with adding a c++ class deriving from DataAsset, then deriving a blueprint from it without actually writing any c++ code
twilit heath
the only difference between the two
is that PrimaryDataAsset is always loaded
while vanilla DataAsset needs to have a hard reference to it from a loaded object, or be loaded manually
remote meteor
hm so not really a concern unless your data assets is like sea level huge i guess?
twilit heath
if you have data asset with hard references to all assets on a level
and you have many large levels
you really really don't want them to be primary
as starting the game would then load every asset you have right off the bat
its not what they are normally used for though
sometimes the data fits a data asset way better then a datatable
and oftentimes, data assets will have soft asset references, and functions to load the assets on demand and return a reference to them
oblique ruin
All my data assets would be is mesh data and material data
And it only needs to be loaded at the start of a match
twilit heath
data assets with soft asset references are excellent for stuff like character customization
as you keep only the meshes/materials you need loaded at any given time, thus reducing your load times and memory footprint
remote meteor
so i be like having soft reference to the assets in the data asset and when its time to use it, i resolve those reference and use them?
twilit heath
the most "hardcode" solution you async load them when they are needed, and trigger a callback in the object that requested the asset, when that object uses the asset and sets a hard ref to it
depending on the size of the assets, you can load sync, it makes the code a lot simpler
oblique ruin
And to create a dataasset that takes soft references Id need to set that up in cpp right?
remote meteor
correct me if im wrong, but the whole idea of this is to prevent every assets to be loaded into memory when lets say a data table is loaded that has hard reference to a tons of other assets right?
instead, it only loads them on demand
twilit heath
no, blueprints can do all of it @oblique ruin
you have soft referene types in BP, you have async load calls
you have interfaces tab around the functions panel on the left
expand it, select a function, right click and you'll get the context menu for it
remote meteor
twilit heath
if the details panel of the function doesn't have the category dropdown, i have no idea
remote meteor
you do that in the inferface itself
hm
interface will only become a (function like in editor) if it has a return value
trim matrix
yep but most of them do not return any value
remote meteor
you can have separate event graphs for your interface though
that can tidy things up
trim matrix
oh, it makes sense nice idea actually
Thanks for your attention i will do that with that way
β€οΈ
oblique ruin
Why is that btw?
If I have a void interface function, why can I not have local variables?

is there a bool to know if the character is level traveling or changing levels?
oblique ruin
I see the primary here (which I take it was the one you said not to use).
or I get this big long list (and I'm not sure which one I should be using.)
@unborn turret You could make a bool in your game instance that is set pre level load, and then on level load switches back to false.
unborn turret
@oblique ruin ugh i hate creating a bool for such a small thing
unborn turret
Any unexposed cpp function that can get me that?
oblique ruin
ns... I'm still relatively green myself.
I'd ask in cpp, they may be able to answer that for you.

you probably ran out of gearing so have to add more gears or lower the gear ratios

verbal magnet
Hello everyone! I have a question... how can I check if 2 text arrays are identical?
earnest tangle
If they need to be identical down to order of strings, you could do a for loop and compare
verbal magnet
im working on a keypad bp, and I need to check if the elements of both of em are identical
number of strings, and the strings themselves
earnest tangle
yeah a loop would work for that :)
verbal magnet
how exactly? I tried a for each loop and checks only if the last string is correct
earnest tangle
so basically you need to have a bool variable like "strings match"
verbal magnet
okay...
earnest tangle
and in your loop, you compare each of them, and if they don't match, you set strings match to false
you can also break the loop
at the end of the loop, from the completed pin, you can then compare if strings match is false
this way you'd know if one of them did not match
mellow stump
JoinStringArray? ive used that to do keypads before, joining all the key presses
earnest tangle
that is actually a good idea yeah, then you could just do a straight up equality comparison :)
mellow stump
press button, gets added to array. press next button, gets added to array. press enter at the end , enter button does JoinStringArray, check that string against a variable you made before hand that has the psscode in it, like, do a Branch, does the JoinStringArray Equal PasscodeVariable
mellow stump
nice
verbal magnet
and how do you apply it to all the elements in an array? you just pin it to loop body?
mellow stump
So, you'd make your passcode an array
verbal magnet
okay... nvm... i think im close
mellow stump
No loop i think there, it just check to see if the arrays are equal

What would I use instead of GetPlayerCharacter to have local funtions like HUD work in online multiplayer? GetPlayerController?
shell wyvern
Do you have any hit or damage event
north igloo
Not yet
shell wyvern
Is this in your actor or is it an projectile or thoug
north igloo
This is just in a function library, so i can apply it in either
shell wyvern
And where do you want to call it. I ask, because you need an actor or something like it to cast to your actor. Also a getcontroller function needs a actor he controls
north igloo
They'll just have the basic third person char, if that's what you mean
so should I replace CastToCharacter with CastToPawn?
shell wyvern
If you want to work with get controller you can say from it get controlled pawn
Or from get player controller
shell wyvern
Wait a minute, I going to show you what I mean, but I need to start my pc first

I'm making a game based on jjba and one of the big key concepts in it are "stands"
for those who don't know "stands" are essentially your "spirit" that you control and all stands have unique abilities
basically weird punchy ghosts with special looks that stand behind you and you control freely
I'm trying to make stands on the right behind the player in a third person perspective
so uhh
any ideas on how that should be scripted?
or just made in general
shell wyvern
Normally you call something with decrease health with damage events. Here are all nodes I mentioned. If you connect the controlled pawn with the cast it would work @north igloo
noble wolf
I know it's way more complicated than other issues but I can't for the life of me do it myself/find a way to do it
so please, if you have any ideas, share them with me
I really need the help
north igloo
I'll give that a try, thanks Benji
earnest tangle
No, you haven't connected the exec pins on the cast
north igloo
other than that π
earnest tangle
probably not because get controller returns a controller, ie. PlayerController or AIController
and I don't think you can cast one of those into a ThirdPersonCharacter
shell wyvern
you can easyly connect damage causer and the object in the cast
north igloo
Yea but I'm trying to get the hit Pawn to recieve the damage
shell wyvern
If the actor you hit should get damage you can just use self as the actor to get damage
north igloo
The variables are asking for a Character Object Ref, how do I generate a self for that, the blueprint I've been using asks for a Player Index

can you change the skeleton of a skeletal mesh?

can you change the skeleton of a skeletal mesh?
@wanton crag you can assign a new one, but that can cause many issues

north igloo
Yes
wanton crag
@shell wyvern i can see what you mean...im trying to add weapons into what i have..and ive completely broke my game. even taking everything out i did...its still broke af
shell wyvern
Then you donβt need any cast or something like that and just set the variables
north igloo
The math is all done inside a function, which is why it's asking for a reference
I figured this would be easier than writing it out for each hit event but guess not
I found it....
I feel beyond stupid now

Would anyone know why an actor "killed" by radial damage is automatically destroying itself after landing? Projectile based deaths seem to work fine (cut the AI controller, activate physics on the enemy mesh, and keep the body persistent), but grenades/rockets appear to be triggering some sort of destroy event I can't find. Note that it only happens after the actors collision capsule lands or falls out of the map, so there doesn't seem to be a certain lifespan getting set. Would really appreciate any and all help!
Forgot to mention, it's not just the mesh disappearing. During PIE, the actors in question flash as "Deleted Actor" for a moment before getting destroyed altogether.

Got an interface with a one function definition, getAnimationBP() ... base class implementes, child class overrides the function. when a function in the base class ia calling getAnimationBP() from a child class instance... the getAnimationBP() of the parent is called and not the overrided one... why is that?

Is it possible to move (translate) an entire level around in the editor?
i.e. some streaming level that I want to move up a bit because I added something below it.

why my linetrace dont appear?

why my linetrace dont appear?
@trim matrix can you tell me how it should works?
oh
i see
humble grotto
maybe it doesn't works because you connect the Actor reference to Interface
could you show me the Interact function?
and
are you sure that you know the direction of the Forward Vector of your camera?
you can use Get Forward Vector straight from the camera
if your Camera object class is Scene Component, it should works anyway
you can use Get Forward Vector straight from the camera

it's very simple
but it works
static charm
so im trying to fiqure out this warning:
LogScript: Warning: Script Msg: Attempted to access index 0 from array 'ComponentTags' of length 0 in '/Script/Engine.ActorComponent'!
but since its not saying which blueprint, im not sure where thats even coming from
ive got a get all component tags in blueprints but none of the blueprints are giving errors or warnings
its like some engine function is glitching out
nevermind found it
still don't get why it wasn't saying which blueprint the warning is coming from
i guess because its a pure function
trim matrix
can someone explain me why my linetrace dont show?

set draw debug type to for duration
static charm
duration needs to be on and double check the start and end locations
trim matrix
already do this
static charm
then your start and end locations are in error, or the function isn't being called

ionic junco
any chance someone who can help with async blueprint is online?
static charm
did it print async loading started?
ionic junco
hm, this node got activated, fires it's own breakpoint, then watched value of it's out pin shows the actual value (you can see on screenshot)
static charm
ah yeah
ionic junco
ah, print, yes it prints
static charm
what is jbox.jbox
ionic junco
actor BP
static charm
what is file.jbox
static charm
ive never seen a blueprint called .jbox as the file extension
can u just pick the blueprint from your drop down in the list
ionic junco
same for me
static charm
or search for it
ionic junco
and it's my BP
static charm
oh nevermind
ionic junco
and I didn't give it a name jbox.jbox
static charm
yes nevermind thats just how ue4 calls it
ionic junco
yeah that what I thought
static charm
do this instead
and see if it prints jbox name
if it does, then your asset loaded
ionic junco
it' actually looks like a common problem. I found a couple of old forum thrads with exactly the same question but nowhere the answer
let me try
btw not sure if it should, but the Construction script of jbox never fires a breakpoint after that
yeah it shows just the name
static charm
yes so it loaded the asset
now u can spawn it or whatever
async loading is just preloading object into memory, not the game/level
at least thats how i would think it should work
static charm
async loading is so you can load and unload big files/assets without lagging game during game startup or level starting, etc.
ionic junco
but yeah I still drop it to the level whe doing it by hand
could you say how can I place it into the level by BP?
after loading
ionic junco
hm wait. Yeah I found it, and it requires a class for input, not an object. And this is not a problem, there is a similar Async Load Class node. but this makes me thing that if Async Load Asset give you an object on out but not the class, doesn't it mean that the class was already instanced and the object created? And if it was created and existing.. why I can't call it's functions and why it doesn't pass the castingπ€
sorry I kind of came from a regular OOP and new in UE
static charm
well im not sure why you only want to async load this one thing anyways
just spawn it
static charm
i guess the async load object is for non actors, like just plain ojbect class
actors can only run in the level/map, so if not spawned or in the level already, then it cannot run, since actors need a transform.
plain object class needs no transform
_
so maybe you wanted to load object that has data only, etc.

Hi, guys, can someone tell me how I can make the blueprint of my character recognize the distance from the ground? (and create a float variable with it)
trim matrix
Hey guys
Is there anyone to gelp me with my problem?
I'm trying to make a thing where when the character gets out of sight (for example when goes inside a room or goes behind a wall) the camera automatically switches to another one that has sight on the character
I'm doing this based on a tutorial but well
How should i say it... There is this free plugin that has a custom camera and wgen I'm trying to kinda make it like.. to switch to another camera it fails, not only it won't switcg it also makes the camera to stops rotating the direction the character goes
Damn... No one?
fleet ermine
I'm not sure where to ask this question... I'm working in a blueprint on a project I'm working on... I was creating a Local Variable named Return and by mistake created as a Variable... Noticed my mistake and then deleted the Return Variable and proceeded to create the Return Local Variable... and it won't let me... I've closed out and gone back in... No luck just tells me "Conflicts with another object in the same scope!"... I can't find a Ref for this in my project anywhere... Can anyone help or explain why this is?
@trim matrix Sorry.. I'm still learning myself and It sounds like there is a conflict between the custom camera and the one you made... Have you just tried to duplicate the custom camera and then have it switch to that?
fleet cedar
do animnotifies have to be received in animBP's? Can you get them in normal BP'S?
trim matrix
@fleet ermine
Well yeah kinda
The thung is i think i know what the problem is, there is bunch of nodes that needs to get connected to event tick but the custom one already has some nodes connected to it
I have to find a way to conncet mine safely to those that are already there
