I'd probably do them as splines
#blueprint
odd ember
that way you handle all the cases, even in the case of off grid
you'll get something along the lines of cities skylines
you'll have to couple that with collision detection etc., and ideally you'll have that be a small part of your road builder blueprint, after which you'd want to put down logic as soon as the spline meshes have spawned
snow geyser
Ill have to read up on splines then, dont know much about them atm lol. Ty it at least gives me a heading
arctic rune
Quick question, how do you group variables, I can see there are already preset groups, for "My Character" and "Components", can I make my own?
dim lily
CranzEstebogen thanks for info on custom events not taking timers, I gues an event for the timer that fires up the actual event I want to repeat? lul
odd ember
depends on what you want to do
distant sedge
@arctic rune Select the variable and there's a Category field. Can have sub groups with | like Food|Breakfast or Food|Dinner
arctic rune
@distant sedge Yeah, but how do I make a new category? It only has 3 options, default, my character and Components?
distant sedge
Type in the text box
arctic rune
Nevermind I was being stupid, thank you xD

rough wing
Hi
I'm trying to add all my velocity into one plane
I don't want my character to add velocity in the yellow direction
This is my code
But it's only working in one way
split wasp
you take your velocity, and project it on a plane
and plane normal is wall normal
bonus: calculate the projected velocity and lerp it with original velocity to control how sticky the wall is
split wasp
well not really, you just added some arbitrary +90 yaw axis to something
when you can actually get the normal_vector with simple trace
rough wing
Oh I see
so the plane normal is not the direction of the restriction
but the normal of the plane were walking on
split wasp
is along the same axis as the wall
if you do the planar projection from ground normal, that would mean you can't jump
arctic rune
Just wondering, any of you have any experience with moving where the player spawns. For example I want the player to enter a room, when they do this opens a new level, if you exit that room you go back to the previous level, but I cant seem to get the player to start where they were before entering the new level rather than at the player start? if that makes any sense π
odd ember
so you want a loading screen level change and keep the player in position of where they were?
fair estuary
@arctic rune you need to store the last known position of the player when they are entering the door. Then when you spawn your character in, you can set the location according to the last known then hand control over to the player.
You can also set the rotation to look away from the door as part of setting the player position
zealous moth
Why not have level entries and exits instead of recording data... on level spawn move or teleport pawn to loading point
odd ember
@fair estuary and how do you propose to do this when the last known position will be based on the previous level's pivot?
upbeat sinew
@arctic rune you need to store the last known position of the player when they are entering the door. Then when you spawn your character in, you can set the location according to the last known then hand control over to the player.
@fair estuary You can store data (Player Rotation, Location) in player Instances, they transfer between level changes
odd ember
the problem is still you're on the new level's pivot, so unless the pivots match up you're not going to spawn in the correct place
older games used a landmark system which was a standin for level pivot changes
fair estuary
The location of a point in the level is always the same right?
odd ember
nope
not if you transition between levels
like yes, if you use a position of (0, 100, 100) that is still equal to (0, 100, 100) in the new level, but at that position in the new level there might not be anything
unless you line everything up flawlessly for every level
fair estuary
Wouldn't that depend on level streaming though? If you're not level streaming then 0,100,100 as the last point in the previous level will still be 0,100,100 in the previous level.
maiden wadi
You wouldn't need the previous level's pivot. Presumably there's a door in both levels next to where the character is starting at after "Walking through the door". Just know where the door is and face the character away from it.
odd ember
@fair estuary this isn't streaming though, first, and second the location doesn't matter. what matters is the level carries the player over to the new level in the exact spot required, not absolute position
you don't need the previous level's pivot
the way old games went around it was by using relative location to an actor
so in the example of a door, on triggering the level, you save the relative location from the door, and when the new level pops in, you transfer to the same relative location from the door
the door essentially becomes a working pivot
karmic pebble
I think he meant to save the location of a point near the door that is rotated properly facing away.
which is what we do for our game.
odd ember
well yeah but that's not the same
that's just spawning the player in a new location in a new level
karmic pebble
Correct. using a direct last known location wouldnt be possible because the last location triggered the change level screen
so you really have to use a point to spawn at based on last known door you went through
odd ember
@karmic pebble not true, since relative location stays relative. if you have an actor that propagates to the new level or put a stand in actor for this exact purpose you can get the exact transform the player had in the previous level, in the new level
odd ember
I don't think so
but it's a question of how much manual work you want to put in
and what you're expecting in terms of level transition
but your suggestion isn't so much changing levels as just spawning a new level with a new starting point
is all I'm saying
anyway with origin rebasing in the engine, that is also a solution, perhaps one that is easier
fathom spindle
Hi all,
I've got values along the extents of a box in y and z that are remapped to zero at the far extents and 1 at the centre and i'm looking for the maths to combine them into a circular falloff where the centre of the plane described by y and z is a value of 1 and then the values scale smoothly to 0 in all directions outwards. Hope this makes sense π
fallen glade
I've got a technical question about blueprint order of execution.
Let's say in a blueprint I cast to another to get some data back for the next node. Does the engine finish whatever the cast told it to do or just proceeds to the next node straight away ?
manic cradle
Is there a way to cast a line trace to a widget actor from scene, and debug detect buttons?
elfin hazel
@fallen glade You need to grab the Actor that the Child Actor Component holds with Get Actor.
wooden jasper
Anyone got any idea as to why only part of my blueprint execution flow is being diaplyed in the editor ?
- It executes all the code, but it never actually displays which route it goes, which is immensly frustrating D:
fallen glade
@elfin hazel thank you very much ! π
@wooden jasper if it's in game you have to select which actor to inspect by a dropdown on the top right
wooden jasper
I already got it selected in the debug info - and it does show parts of it being executed - like at the end of a chain it will show like this: the execution starts at the event to the left :S
fallen glade
I've had the same problem before, sorry, can't help
how do you expose child actor variables ? :/
wooden jasper
There's a get function from the component you can use
fallen glade
@wooden jasper ?
odd ember
@fallen glade child actors aren't a good way of doing things. they're buggy and highly expensive for almost no gain
there are probably other, better ways of doing what you want to do
fallen glade
I was just trying to crate a debug level for my debris... the plan was to spawn the required debris from a list
@odd ember i'll find some other way
wooden jasper
I think its called Get Child or something like that @fallen glade
fallen glade
@wooden jasper thank you, problem is variables are not exposed. I need to find another way
elfin hazel
Think your best bet is to set all the variables after its created and then making an event that is called, instead of begin play, when that is done. probably easiest to make a function that takes all the data you want to set.
odd ember
@fallen glade so why don't you use the SpawnActorFromClass node?
fallen glade
I need the variables to be exposed on spawn :/ I think I found another way
odd ember
@fallen glade if you tick the expose on spawn tickbox they will be exposed on the SpawnActorFromClass node
that is the correct way to have anything spawn an actor in the world
elfin hazel
If you're doing stuff during construction, move it to a function you call.
There's also this: https://issues.unrealengine.com/issue/UE-62458
fallen glade
Another requirement is to spawn before begin play .... thank yopu for letting me know of the correct way @odd ember but this i'm making is just for testing purposes
odd ember
@fallen glade begin play of what?
fallen glade
in construction script
odd ember
so you're doing it while in editor?
fallen glade
yeah
odd ember
shouldn't make a difference
the actor will still spawn, but no logic apart from its construction script will be executed
fallen glade
SpawnActorFromClass can't be called from construction script
odd ember
I see
odd ember
so can you talk me through what you are actually trying to do?
elfin hazel
You can use an utility actor.
odd ember
a debug level for your debris doesn't exactly tell me anything
odd ember
so like a preview scene
odd ember
that seems like functionality that already exists for destructible actors
fallen glade
while keeping the ability to toggle variables
odd ember
you're doing an editor extension in either case, so you'd need to use utility blueprints, not regular ones
odd ember
yeah, the workflow is different but the idea is the same
you'll have to think about UI as well etc.
fallen glade
mmm, i'll look into it ! thank you
odd ember
might be better for you instead of attempting to shoehorn functionality in where it can't or won't go
fallen glade
I guess
odd ember
@signal cosmos #animation
terse harness
hey, when I have an instance editable object reference var in the gamemode bp, where can I set it in the editor?
severe iris
Will False && B evaluate pure function B?
Pretty sure it will, but need confirmation as this looks a bit weird and unusual to me
tulip iris
Should actors construction scripts be running in editor if their the streams they are on are not visible/hidden? I have actors that are all running construction scripts even though they are on a hidden stream.
odd ember
@terse harness you... can't really
game mode isn't an actor, it's an object
its instantiation is concealed from the editor
@severe iris shouldn't no
true || and false && don't evaluate secondary conditions due to optimization
at least in code
but I doubt the wrapper is different
odd ember
by wrapper I meant the BP wrapper
but there could be some edge cases wherein for instance a select node would evaluate regardless
severe iris
For example try length(array) == 1 && array[0]==something
This throw an error in console for me
odd ember
so if it throws an error then it probably evaluates both, depending on the error message
severe iris
Yes, that's what I'm saying, it complains on illegal access on empty array
odd ember
you can debug it to see what the actual evaluation is
but it might be that the BP VM can't not evaluate
terse harness
@odd ember ok thanks, what is the best way to call an event in another bp from the gamemode bp then?
odd ember
entirely depends on what you want to call
generally though the game mode shouldn't call anything, but rather listen in on calls made by others
terse harness
ah ok, I should probably just call it from somewhere else then
odd ember
what are you trying to do?
terse harness
call an event in a specific actor in the level that sets the visibility of the actors widget component
odd ember
can you be more explicit? like a UI for a player let's say?
thorny cedar
is there a way to check if a device is plugged via USB?
terse harness
ok, there are 2 power switches in the level, when both switches are flipped within 2secs of eachother, the power turns on, activating a display on a keypad
i was using the gamemode bp to check if the switches were flipped close enough to eachother
terse harness
yeah
thorny cedar
2 Problems.
- When my window isn't active my vehiclepawn is moving. Shall i simply pause the game, when the window isnt active?
- When my Joystick isn't attached unreal still recognise a joystick input
odd ember
ah right the display on a keypad is in world as well, right?
in that case just use the level blueprint
odd ember
@thorny cedar 1: yes. 2: this one is a bit harder, are you cpp familiar
thorny cedar
my project is cpp based, but im glad if you can help me to dig deeper into cpp, if its not that hard
odd ember
@terse harness so widget components generally need to go on actors that use them, unless they are placed arbitrarily in world. e.g. a 3d "screen" with widget choices
thorny cedar
have to use cpp files for some config file for a 6DoF simulator
odd ember
@thorny cedar I don't know it on top of my head, but I suggest you look through stuff like PlayerInput.h/cpp to see if that links out to some USB connection. from there you should also be able to look for links to hardware delegates
thorny cedar
how can i check, if my user has the current UE4 instance active?
any variable of player classes?
tropic tide
It says this is an infinite loop. Why? It has limited amount of overlapping components, so how?
odd ember
@thorny cedar probably somwhere in GameInstance
tropic tide
ok, so I want to make explosive barrels that make other barrels explode, but it seems the barrel also targets the barrel that made it explode which creates infinite loop, how can i prevent it?
I think I fixed it, but now it errors so hard, it sends me to to standard macros blueprint
still nexus
how do i triger an event in widget BP that is defined in actorBP and this actor is casting to a pawn BP.
odd ember
how is it defined in actorBP
still nexus
odd ember
where is the widget
little nacelle
for enemies that drop loot, is it better to use a BP interface or just a custom event within the master enemy class?
still nexus
widget
odd ember
where is the connection between widget and actor?
@little nacelle depends, are enemies the only type of interaction that drop loot?
still nexus
i added an object reference to the actor
the print string is working but the event isn't
little nacelle
they are not, however if i was to use a BPI wouldnt the "killer" need to be the caller?
like there will be enemies and destructible objects
both can drop loot, with varying logic on rolls
odd ember
so what's the issue?
@still nexus can you show me the object reference in the actor?
and the logic
little nacelle
well the logic flow seems weird no? On the enemy's Event Any Damage, when it is killed, it has to tell the killer it has been killed, who then talks back to the enemy to tell it to drop loot, seems like unnecessary steps no?
odd ember
why would the killer need to be involved?
little nacelle
isnt the killer the caller?
little nacelle
then whats the point of using BPIs?
still nexus
@odd ember i didn't make a widget reference in the actor i only made an event and then call it in the widget on button press
odd ember
@still nexus then how do you expect it to know the widget?
@little nacelle the point is to have the same structure of functions for multiple hierarchies. e.g. you can Interact() with both a door and an NPC, but they each have their own implementation
little nacelle
right, so the one that interacts with them is the caller
odd ember
in that case yes
still nexus
do i have to reference it as a variable type object or cast it in the event
little nacelle
so in my situation wouldnt the player need to be the caller?
odd ember
in your case the player killing them just kills them
the player doesn't cause them to spawn loot
THEY have behavior that causes them to drop loot or not
but the player doesn't know or care about that
little nacelle
defined by the BPI's event?
little nacelle
im just a bit confused because im trying to see why i wouldnt just make two custom events
still nexus
ok thank you sir
little nacelle
seems like implementing a BPI for 2 master classes is more work than that
odd ember
technically you should only start implementing interfaces when it is required, and your structure should be setup beforehand to make them work
so it'd just be a hook in
little nacelle
and how do i differentiate when its required? something like your example?
odd ember
what you're probably looking for really is a loot manager
which is tied to a spawn manager
little nacelle
yeah i should really make a loot manager
odd ember
so when you spawn an enemy, the enemy has certain gear that you probably want to consider dropping on death
because once the enemy dies, its cycle of responsibilities die with it
little nacelle
well my current project is a diablo-clone, so its just RNG loot, but the rarities and quantities will vary by enemy
odd ember
diablo 2 still had an approximation of this
where if an enemy was carrying e.g. a spear they would have a higher chance of dropping a spear
little nacelle
yeah i used to think diablo randomly generated items from base ingredients, but then learned they had base classes for each item with a layer of randomization instead
oh thats good to know
TIL
odd ember
do you know cpp
odd ember
no bueno
little nacelle
as in, took 1 class lol
odd ember
this would be a perfect candidate for a subsystem
little nacelle
is a manager class the BP alternate?
odd ember
it's a UE4 specific cpp implementation that works as a manager class
it's just set up to work like that
odd ember
there is no BP alternative
little nacelle
so a custom BP it is lol
odd ember
yea essentially an object that runs in the background and receives calls to do certain things when necessary
little nacelle
yup yup
odd ember
don't think you can do an object even in BP though
so you'll probably have to make it an actor
which is just extra faff
little nacelle
i mean you can create a BP of class Object
odd ember
yeah but you have no way of calling that in every object
since it doesn't exist in the world, it isn't known by the level either
little nacelle
oh, yeah. could make it an actor component and attach it to the player i guess too
but yeah thats how my inventory manager works. its a BP Actor attached to the player
odd ember
why would you attach it to the player?
and hopefully not a child actor
inventory you can do with components
child actors should be deprecated already smh
little nacelle
let me check
so on begin play my controller spawns the inventory actor object and attaches it to the player
the player isnt a child actor btw
odd ember
well no of course not
but that kind of setup is fine
or well
it could just as well be a component
but if it works it's fine
odd ember
it just precludes you from making it modular without extra work
odd ember
yeah there's a lot of issues
little nacelle
so whats the "proper" way of handling inventory in BPs?
odd ember
it's not part of the actor itself so you'll have to make manual hookups every time you use it
there is no direct reference between them, that is something the controller has to handle
little nacelle
oh, yeah i know, ive got InventoryRefs all over lol
odd ember
where the controller shouldn't be involved in this case save for inputs
in the background the technical debt is already accruing
little nacelle
oh i know, ive actually been meaning to do a whole project cleanup, because i know i have unnecessary refs and casts that could be improved upon
odd ember
the sooner the better
little nacelle
i wonder if GameInstance could be an inventory handler?
odd ember
technical debt has a tendency to spiral out of control
and will prevent good design and architecture down the line
little nacelle
yeah its already become exponential for me, and i have a barebones project
odd ember
really it just needs to be a component on the player character
little nacelle
my biggest issue with my technical debt is i dont know the "right" way of BP communication yet
because tutorials always show the basic logic, but dont inform you that its not how youd want to actually do it in a whole project
would it need to be something else if there was a global inventory?
like a shared stash couldnt be character specific, so im guessing that would be stored elsewhere?
little nacelle
yeah ill convert the inventory logic to an AC
so what you said earlier, in this kind of game, id have a spawn manager, that then uses a loot manager?
im guessing when it spawns actors, it decides the loot tables then?
odd ember
you want the loot table to be decided at the end, not at start
because gameplay can influence loot
if you follow the concept of diablo's loot system
odd ember
yeah or anything else
little nacelle
yea lol
little nacelle
thats a good point
tulip iris

arctic rune
So I know instances can be kind of hard to use with blueprints, but are player instances and game instances pretty much the same, as in I can use them the same way?
arctic rune
Hmm, can I save values to a player instance like a normal actor or does it require a bit more work and complexity
arctic rune
Hmmm no, I was told to save the player location in player instance so that it keeps the values between level changing
odd ember
no such thing
arctic rune
Im basically trying to get it so if you go through a door a new level loads, if you go back through it you start at the same place you left, but I cant seem to get the location to save or teleport there and Idk what the issue is
arctic rune
So i could save the player location and rotation in a game instance then cast to that and use that to teleport the player?
odd ember
you could
but
consider that saving the location and rotation and transferring that to the new level will have you teleport into those exact coordinates of the new level
not necessarily where you want it to teleport
arctic rune
So basically I have this so far, Im not sure why this dosnt work, Im pretty new to Unreal Engine so apologies if this is something really basic
arctic rune
Thats in the FirstPersonCharacter - And you spawn in level one (First person example map) if you go through the door - The top code - It loads the new level and starts at the player start. If you go back through that door - Back to the first level - You spawn at the player start and dont teleport to where you were last in that level
If that makes sense xD
arctic rune
Your refering to the set locatation and rotation?
odd ember
yes
arctic rune
Okay I fixed that
arctic rune
Nothing changes
arctic rune
Stupid question, i have to create a new blueprint for that right? Or is there a preset one?
odd ember
the game instance exists, but only as a cpp base
arctic rune
Also in game instance the keyboard E wouldnt work would it? Because its not being controller by the player?
odd ember
it would work eventually, probably even before pawn
but I can't remember the input hierarchy
arctic rune
It dosnt let me add the event in the instance
arctic rune
Uhmm, Idk what that means xD
odd ember
it means you trigger the custom event by putting a volume trigger or what have you in the level
arctic rune
Im not sure what triggereing by proxy is
odd ember
or just have it trigger off begin play after a delay
whatever you want really
we're just testing
arctic rune
Im not sure how I set this up or how to use the volume trigger
Surely that is only in the level blueprint
odd ember
well yeah
arctic rune
Im so confused
arctic rune
Yeah I can place it in the level, no idea what to do now....
odd ember
is it placed?
arctic rune
It is
odd ember
so on component overlap event in the level blueprint, cast to player character
the get game instance, cast to your new game instance class
then call your event
arctic rune
When calling the custom event what would the target be?
arctic rune
Nevermind I accidently casted to the class rather than just the instance
fathom spindle
Hi, does anyone know a good way to set a boolean based on if an actor is in the player camera frustrum? I'm working with an HMD and thought there would be a way to get the view pyramid of each eye and just do an event overlap but i cant seem to figure out how to do it. The actor will be hidden in game/have an invisible material on it.
odd ember
@fathom spindle check out the WasRecentlyRendered node
otherwise do it mathwise

@pallid vector scroll to the far right on your message log and click the farthest right white magnifying class
That will tell you the exact node that's bugging, then screenshot that and post it here

That's the output log
we need screenshots of your Blueprint, where the magnifying glass takes you
@sand solar sounds like you should just start the game, then immediately call your pause functionality
fathom portal
What is to the left of "Get Consumo" and the branch?
Looks like you're calling the "Get Consumo" after you try to use it, which means the value will never be set, but need to see the code before to be certain
fathom portal
Which "then" number is the branch and the "Get consumo"?
Make sure the "Get consumo" is before that branch where you use it
fathom portal
sand solar
@fathom portal Thanks for the assist! I'll give it a try π
fathom portal
Right, yeah, so you're setting the value at the "then 9", but using it before that at the "then 2", when it won't be set and will always break
And yes, agreed, that's... jumbled to say the least lmao
odd ember
not to mention the performance hog it must be
pallid vector
Right, yeah, so you're setting the value at the "then 9", but using it before that at the "then 2", when it won't be set and will always break
@fathom portal
so this is the solution?
fathom portal
I mean, that's one way to do it
Yeah
Depending on what's after the "set consumo", you might just be able to use the branches afterwards
fathom portal
Glad I could help
I recommend organizing a bit
Might help fixing stuff in the future
@sand solar hows it looking?

That did the trick! Not sure why I didn't think of that earlier haha π

Sure man, everyone needs a little push once and a while
Little nudge in the right direction. You already had all the ingredients

@latent shadow are you setting default values for the map?

No, all assigned at runtime
odd ember
have you tried debugging to see what <k,v> are stored inside the map?
latent shadow
Yeah, It seems to be assigning correctly. Im trying to do it with an array right now, and it doesnt allow me to get a reference when accessing it in a function
only get(copy)

I get a popup saying "array get node modified: now returning a copy"
odd ember
idk, might be something about particular data types only being gettable as copy
latent shadow
Weird, Ive indexed widgets and then retrieved references to them before

maybe it's this particular widget type?

Unless theres some class setting that allows it, it shouldnt be. This widget is just parented to the base class and doesnt have anything very advanced going on in it

Yeah but like, how :l
manic maple
Hey all... How can I get two players to both view the same camera by default?
zealous moth
When you spawn a widget it is assigned an owner's viewport. Get player xontroller or get viewport owner.
manic maple
Posted in Multiplayer chat but doesn't look too active. Some questions gone unanswered there.
zealous moth
Set active camera to a same actor
spark robin
But its supposed to be fetching info from multiple players
manic maple
How do I do that? @zealous moth
Tried just calling set view target on begin play
Works for Server but not client
spark robin
(Ping me on further replies)
manic maple
Client for some reason just snaps camera view to his transform
Server view^ [correct]
Client view^ [wtf]
Any ideas vastly appreciated @zealous moth
Feels like this should be simple to do π
spark robin
You have to multicast it
manic maple
Sorry for being a noob. Replication and multiplayer is something that's difficult for me to grasp
zealous moth
I would say more but i am babysotting
manic maple
Setting it to multicast does the same thing Daniel
spark robin
For the clients to be able to recieve the data, it must be casted to them. And multicasting can only be done from the server.
So try placing a second custom event after your current custom event, which you set to multicast
So by your first custom event, you make sure the code is running on the server (as clients can not multicast), and by the second custom event, you tell the server to multicast it (cast it to all clients)
zealous moth
@spark robin you can also send data via event dispatchers and have players subscribe it
spark robin
You mean by custom events basically?
zealous moth
Ans event dispatchers yes
manic maple
Yeah I don't get it... Sorry. This is pretty tough for me to wrap my head around π€
zealous moth
Casting implies finding owners and define their vars. Dispatching simply sends out var signals and whatever 8s listening or subscribed uses it
spark robin
Fletch Im not that certain that its gonna work if you do what I said tbh, I really dont know if the code you sent in the screenie works in your caseπ€·π»ββοΈ
manic maple
Strangely now I've set it to this, it works for the first couple of frames and then snaps the camera back to the actor transform on client:
Spawns, loads in correct camera, then puts camera back to actor transform
π
No ideas?
π’
manic maple
What do you mean 'assign a camera'? Can you please elaborate?
That's exactly what I'm trying to do with the view target
spark robin
@manic maple I believe your switch on authority's outputs are supposed to be the other way around, if the device running the code has authority, its the server, and should then multicast, if its a client, it has remote access and should send to server
I've never used the switch on auth myself tho, so I might not get it right (You dont need the switch on auth, its a unnecessary step in situations like this)
manic maple
Switching them makes no difference unfortunately
Just sets correct camera for a few frames, then switches back to default camera if there is a camera component in the player Blueprint, or to Actor location if there isn't one
spark robin
Lol, just a cheap idea
But if you like, Try removing the camera that belongs to the other character if you can (The one its switching to unwillingly)
manic maple
I have tried with and without camera components.
manic maple
It snaps the view to the actor location
If it does have a camera component, it uses that instead
Either way, it shows correctly for a few frames, then switches to one of the above
Only for the client though
Server works fine
spark robin
Thats weird, I've never played around with separate cameras yet, so Im the wrong guy to help with this
Actually
I have an idea
manic maple
I'm all ears if you can help me out right now because I'm at a loss, haha.
Really would like to get this working π€
spark robin
Try duplicating what I circled in, to where my arrow is
So then the code will first run on the server, and then on the clients
This can be due to some checks the server does to make sure the client has the same config as the server kinda (I discovered this myself like a week ago when I first started working on multiplayer stuff)
manic maple
Huh?
spark robin
Aw okay
manic maple
You can see it cycle through on the client when I run
It sets it correctly for a moment, then decides 'nah, that's too easy' and fekkin' changes its mind..
Apologies for the frustration..
Would love for @zealous moth to explain what he meant exactly, he seems to know what's up :l
zealous moth
Babysitting. No computer around :(
manic maple
Any ideas I can try based on what you've seen at all?
spark robin
Do you have multiple of these cameras?
manic maple
No, just one.
Hence getting 0 in that array should get the only one present in level
spark robin
Can you try putting a string here and see how many times it executes?
If it executes more than once, maybe its picking up on some camera you dont want it to (Tho Ik you said you only have one, just to make sure)
spark robin
Then I think its picking up on another camera
manic maple
No, that's the loop to check for player controllers
It's not looping through cameras
Unless I'm missing something
spark robin
No, Im not familiar with loops, you might be right, its just a thought
manic maple
Getting all actors of the camera class isn't on a loop
It's getting all instances of player controller
Which I'm guessing is right at it printing two? Since there's two players spawned in?
true yew
are you sure you really want to do exactly this? there are basically 0 real life circumstances where it seems like a good idea to force-update a camera position from the server to clients. what are you really trying to achieve?
manic maple
I'm just wanting all players that spawn in to have the same camera view
How can I achieve it otherwise? Can't find any solutions anywhere π
odd ember
but... why?
true yew
well how does the server calculate where the camera goes, very generally (I haven't back-read)
manic maple
Because that's how my game is intending to work... This camera view needs to be fixed and not parented to the player.
Multiplayer replicated, one top-down view.
That's all I'm tryin' to do
true yew
like Gauntlet?
manic maple
Yep, looks right.
Never played it, but yeah, any multiplayer game with just one camera...
true yew
take the code that the "server" uses to calculate where the camera goes, and run it on every client instead?
manic maple
Alrighty... How do I do that?
Because that's pretty much exactly what I'm trying to do?
spark robin
Do you guys know how to destroy widgets btw (To avoid memory leak)? (Please ping on reply β€οΈ )
odd ember
remove from parent
manic maple
Remove from parent should destroy it no?
Or at least garbage collection will if it's no longer attached.
surreal peak
Yes and no. The GC will destroy it.
manic maple

surreal peak
You have to also clear references to it if you have any.
manic maple
Hey Exi, do you have any idea how to fix my issue at all?
Hojo rolled up seeming to know what's up but hasn't followed through. All I'm looking to do is run a multiplayer game with one fixed overhead camera view, just like street fighter, say. Would very much appreciate any input and advice @surreal peak
surreal peak
The ViewTarget stuff?
manic maple
Sorry Hojo, didn't mean any disrespect there. That sounded way too passive aggressive
Think I'm just frustrated with this.
Mean no disrespect brother, I'm grateful for your input β€οΈ
Yes, that's what I'm talking about Exi
One camera. Multiple players.
surreal peak
Is the camera in the scene?
manic maple
Currently the camera is a separate Blueprint actor.
Hovering above the scene. The only way I could think to do it is by setting view target.
This works perfectly on the Server, but not on Clients.
surreal peak
Yeah, set the ViewTarget in BeginPlay of the level, or BeginPlay of the PlayerController, limited to the owning client.
And turn off the AutoManageCamera stuff in the PlayerController settings
The stuff you posted at the start, for what i saw, is total garbage :P
manic maple
I have no idea how replication works, I'm just now trying to figure it out. Could you please direct me on how you'd do it then? On the Level BP? Wouldn't that cause issues when it comes to dying/respawning?
true yew
the camera (your camera blueprint actor) should know how to position itself, e.g. by calculating the average position of your players or whatever you're doing. there is no replication involved in this
surreal peak
That's why you turn off autoManageCamera shizzle in the PC
manic maple
I can't see any auto manage camera options in the class defaults?
surreal peak
Could also be on the camera manager
manic maple
How would you achieve what I'm trying to, Hojo?
odd ember
(player1.position + player2.position) / 2
manic maple
I'm not calculating anything @true yew all I want is just to have one view for multiple players. Default view seems to set based on the character having a camera component, and if it doesn't have one, it'll just snap the view to the actor's location. If there's another way to set the the default on this I'd love to know
surreal peak
bAutoManageActiveCameraTarget
true yew
well back up a bit. what "sets" the view you want to have? is it hard-coded into your level? is there code on your server that runs to set the camera position?
surreal peak
That's the boolean
manic maple
I'm using a default 3rd person template? Whatever sets the view by default. I don't know? It uses a camera component if the player BP has one
surreal peak
Turn that boolean off in your PlayerController and it will stop automatically giving the pawn the camera view
Then you can just set the ViewTarget in the levelBP or on BeginPlay of the PlayerController itself, limited to IsLocalPlayerController
true yew
i'm trying to figure out how to ask this. this isn't supposed to be a trick question or anything. what causes your camera to be 100 feet high up in the air and pointing downward? did you place it by hand, does code move it there, what?
true yew
ok, if the camera doesn't have to move, you put it there, you just need everyone to use it - listen to eXi
manic maple
Exi, having done this now it worked. Thank you x1,000,000. You are a legend. Thank you so much.
[I am still kind of confused as to why exactly. Why did it continually override? I'm not complaining I just want to try to further my understanding]
surreal peak
The PC and the PlayerCameraManager usually take care of the ViewTarget. Which is an Actor. Camera components only offset the view. If that boolean is true, then the PC will set the ViewTarget to the possessed pawn/character. And what you did earlier with BeginPlay and rpcs and what not is just doomed. You can't just hope for all players to be connected at the same time.
Man, i hate typing on phones sometimes..
Anyway, glad it helped. I'm off now, catching some sleep.
manic maple
Thanks Exi, appreciate it

Is there a way to keep the physics volumes visible during gameplay?

Any Eye Deer why a box collision would not trigger the first time you enter it? Player walks up to a chair, it allows them then to sit, but just not working the first time I enter the space for sitting in the chair
spark robin
Hey everyone, so for some reason, the branch in the screenie always outputs already hit for some reason.
Im trying to get around on component begin overlap getting triggered multiple times as my mesh overlaps a players mesh, if you have any other solutions for this, feel free to suggest (The entire thing is inside of a bullet/projectile blueprint, so I always want the bullet to only run the code after the branch once for each actor it overlaps, the reason to that I dont just destroy it first time the code runs is that I want the bullet to be able to hit multiple targets before it gets destroyed)
Im going to bed now and will be reviewing any responses tomorrow, so please ping me if you have any ideas/knowledge about this β€οΈ
forest basin
and sometimes it ignores the rest of the event for sitting IE stopping character movment
Why is something as simple as sitting in a dang chair being so complicated.
true valve
@fathom portal I don't see it for physics volume.
forest basin
Hmm could it be that its a problem with the collisions between static and skeletal meshes?
Its setup so the chair is not part of the BP, its just a blank sit down location BP so anywhere I drop it the player can sit. Since Static and Skeletal meshes do not like each other, Should I just add the mesh to the BP and just change the mesh based on the situation in the map?
fathom portal
@true valve have you tried the show collision command?
And I tried the command for myself, and figured out why my collisions were only running when walking right.... Because my right flipbook was apparently set to collisions every frame!

Here is my BP for changing the color via sliders on a material. I am storing the values however when trying to change the same material on another pawn it wont work, the rgb values transfer over fine, its the Set vector param that is not working.
odd ember
what's the error?
odd ember
my guess is that you're still targeting the first pawn
twilit lily
They share the same material tho?
odd ember
no such thing as sharing
twilit lily
Well I mean both are set to the same material
I'm not changing anything about the pawn but more so on the material side.
odd ember
what's the code for the get player controller?
twilit lily
I don't think I reference the pc
only the game instance
Wait
Yeah no I don't
I'm just storing the rgb info to the GI
Which works fine
odd ember
what I meant was what is the code above with the player controller
odd ember
well if that widget is where you change colors
you're only changing colors for player 0
so the first player
twilit lily
Yes
Thats correct, thats why I'm storing the info in the game instance
So I can pull it later for the real character
odd ember
well there's your answer for why it doesn't work
twilit lily
It's not supposed to change the real characters color until its created
hence why I pull the stored rgb info out of the GI
odd ember
I mean you asked about why it doesn't color the second pawn
twilit lily
and try to set vector param
odd ember
I understand what you're trying to do
twilit lily
Okay
odd ember
it's not really relevant for what I'm saying is wrong
twilit lily
Is there a better way to go about this?
This was the only way I could think to do it
odd ember
where do you hook up your pawns
twilit lily
Well I have a color changing level
odd ember
there are of course better ways to do this
twilit lily
Huh yeah, always a better way xD
odd ember
but honestly at your level it's going to be hard to suggest something that I would be able to give to you to build
twilit lily
color changing level is for what I call displayball
odd ember
like a lot of this is complex behavior
odd ember
so of course it's not easy to get right
anyway show me your pawn setup
maybe I can at least make the second pawn work out
twilit lily
This is the fake pawn
essentially just for show
the real pawn
Has a lot going on
Movement and timers
So it can't be used to display color changing
The gamemode info for the display ball
odd ember
Let's go back to this
Just doesn't change the color on the 2nd pawn
@twilit lily
twilit lily
Okay
odd ember
so you can't change the 2nd pawn
twilit lily
odd ember
what is the first pawn? your display ball?
odd ember
where is this logic setup?
twilit lily
The sliders?
They are what changes the first values
Thats one example
which ties into
odd ember

this image is why your pawn isn't being colored
you're casting to display ball instead of ball
odd ember
I see
so your setup is
you do the color change, click ok, then spawn the level expecting the color to be on the pawn
trim matrix
Did you assign the dynamic material instance to a material slot on the ball on beginplay or in the construction script?
odd ember
probably the ball pawn doesn't have a dynamic material instance
twilit lily
trim matrix
not sure if that works
twilit lily
Mat BGIInst is a copy of the dynamic instance from display ball
trim matrix
like if it's saved
odd ember
where is your ball pawn blueprint?
twilit lily
Ok
odd ember
and THEN set the color by the stored values
odd ember
might not work in construction script but give it a go
odd ember
yea
construction script is really just if you want to do something with the actor at editor time
twilit lily
oh
erm
Still not working
Im going to triple check the rgb values with print
Yup they are stored correctly
trim matrix
are you sure the parameter is called Color?
twilit lily
100%
It works with my other pawn
All im doing is storing those values that get set and sending them to this pawn
odd ember
put a breakpoint and see if those values are actually saved
twilit lily
breakpoint? uh let me try, never used it before
So its not values
This doesn't even work
Which should just be red
I did confirm that the Ball is taking this mat by manually changing it to a different color
Here is the Material
twilit lily
Good idea
ill try it
Awesome
Its working now
Got it all plugged in
Man those small things can really get ya xD
odd ember
@twilit lily so the set material is something you'll need to do every time you want the material values committed
twilit lily
nice to know
trim matrix
@twilit lily btw if your mesh only has 1 occurence of that parameter name amongst all of the materials you could also not use a material instance dynamic
twilit lily
I see
trim matrix
this is the construction script
twilit lily
Whats the big dif between a construction script and begin play?
trim matrix
odd ember
it's a bit more complex than this but that's the gist

Is there a built in way to draw things in the viewport of blueprint editor on a generic and shared basis?
Say I have an interface that defines some stuff that I'd like to visually show in blueprint editor's viewport. Is there some way to add in some lines based on a selectable view or something? -- as in the show menu or broadly

not entire sure how you would draw something like this. for sure there's nothing selectable. there might be a console command, but it also kind of sounds like it could be solved with a print string?

maiden wadi
@gloomy nexus I'm not an expert, but I don't believe you can construct objects deriving from UObject starting from Actor and beyond. You should be able to use the SpawnActorFromClass node instead though.

Hi all, I'm using an HMD and need to get the GetDotProductTo of my Camera component and an Object referenced in my scene. The node only accepts actors, does anyone know how i could get the 'self' to update with the camera ie HMD movement?
odd ember
@fathom spindle .... why don't you just use vectors for the dot product?
I'm not sure if HMD has the same setup, but you can try with SetControlRotation
fathom spindle
i thought there was a difference between regular dotproduct and getDotProductTo
fathom spindle
i guess none!
thanks π
Hi @odd ember the regular dotproduct doesn't seem to work for me, am i doing something wrong?
just prints as zero
odd ember
if the dot product is 0 then one of your vectors is 0
use breakpoints to debug
also!
keep in mind if you're looking for directional overlap with the dot product you will need to normalize vectors
fathom spindle
ah ok so i should offset my player location a little and normalize both incoming vectors?
odd ember
well it depends on what you're looking to do
the dot product is literally just a product of both vectors multiplied by each other
so if one vector is 0, the dot product is 0
fathom spindle
im looking to get a value for how much my HMD is looking at this actor
odd ember
that's directional overlap
so yes, normalized vectors
normalizing a vector generally means you get a direction instead of a distance
fathom spindle
ive done that and now it does update with the HMD view rotation but the values are strange. -0.05 when its facing dead on, -0.1 when its 90 degrees away
odd ember
ah it's not that bad
odd ember
no need
well most likely no need
normalized dot product spans a range from 1..-1
1 is dead on, -1 is the view directly opposite
0 is at either 90 deg angle
fathom spindle
is it this tolerance float?
odd ember
the tolerance isn't something you need to touch
fathom spindle
0 is at either 90 deg angle
@odd ember thats what i was expecting but im getting these strange small values
odd ember
breakpoint and cehck the vectors
well actually
for the camera
use the forward vector instead of normalizing location
for the secondary vector, use (camera.location - otheractor.location).normalized
that's going to give you the direction directly from the camera to the other actor
versus where the camera is pointing
odd ember
well try it
fathom spindle
gives -40 facing, zero at 90degrees in x and 180/-180 in y
odd ember
you normalized one before subtracting
odd ember
I wrote it previously my dude
cinder relic
What's the difference between UMaterialInstance and UMaterialInstanceDynamic?

@cinder relic don't think you're in the right channel, but dynamic instances can be changed on the fly and reapplied. instances are just cheaper versions of actual materials

spark robin
So for some reason, the branch in the screenie always outputs already hit for some reason.
Im trying to get around on component begin overlap getting triggered multiple times as my mesh overlaps a players mesh, so Im trying to make it so that the branch checks if the actor its overlapping has already been overlapped once, if it has been overlapped, I dont want it to do anything, if it hasn't, I want the code after the branch to continue to run (The entire thing is inside of a bullet/projectile blueprint, so I always want the bullet to only run the code after the branch once for each actor it overlaps, and why I dont just destroy it first time the code runs is that I want the bullet to be able to hit multiple targets before it gets destroyed, so I were planning to set up some sort of a health system for the bullet that would then run directly after the code in the screenie to have the bullet get destroyed after that it have hit enough obstacles to fully drain its health)
Is this what Event Hit is for? I tried using a Event hit event node earlier, but I didnt get it to pick up on anything, despite having "Genererate event hits" set to true. Physics for the bullet is however disabled (As I simply dont need that), is event hit only for physics sims or should I be able to use it for stuff like this? Or is there another event node for this (A event node that will only trigger once per overlap for each actor it overlaps with)?
(Please ping on reply β€οΈ )
I dont event get why my code doesnt work in the first place :l I feel like it should

I'm realising my character has no velocity... :/
When I Print Player Character's velocity in debug mode all X Y and Z stay at 0.
Am I missing something ?
trim matrix
Character Movement ?
atomic salmon
yes
atomic salmon
The generic Get Velocity only works for Primitive Components
hollow cape
@trim matrix ....it looks like you're printing velocity 1 time? Are you getting it on tick or something?
atomic salmon
@trim matrix are you printing it on Begin Play?
hollow cape
looks like it's being printed once, on what I'm assuming is begin play
so yes, it being 0 makes sense
trim matrix
Oh yes it's on BeginPlay
atomic salmon
Begin Play is executed only once
hollow cape
yeah it's not going to show anything other than 0 since it's 0 at beginplay
atomic salmon
so you have been showing the initial value for 1000 seconds
and the initial value is obviously 0
@spark robin the best way to do that is to use a boolean flag for the overlap as a gate
on the initial overlap you set it
then you use it to prevent any reaction to any other overlap
finally on End Overlap you set it to false so the next overlap can be detected
another way to tackle this is to use a DoOnce after the first overlap and reset it only on End Overlap
trim matrix
Ok, it displays the Velocity but according to World axis, so there's minuses values.
hollow cape
vector length
velocity -> vector length -> print
if you want to ignore Z velocities (ie falling/jumping), do vectorlengthXY instead
atomic salmon
@trim matrix in general, all physics quantities are in world coordinates
you can transform them in local space if needed
Feed in the the world transform of your character and the velocity vector
with that you have your velocity in local space
trim matrix
I'm using this value to affect something else in fact.
spark robin
@atomic salmon Oh, I didnt know about End overlap! Is there any chance it might bug tho? Im thinking if it overlaps 2 actors at once
I will try it non the less, thanks β¨
atomic salmon
@spark robin if you want to detect a specific actor to Begin or End Overlap, you need to cast Other Actor to the actor you want to detect
Other Actor is one of the outputs of the Overlap events
Say you have a BP_Sphere and a BP_Cube overlapping a trigger volume. If you want to detect only the BP_Sphere at a given time, just cast Other Actor to BP_Sphere. In this case the cast will fail if BP_Cube overlaps the trigger and you only do something if the sphere has overlapped.
trim matrix
I would like to make the Velocity equal to another Value if that makes sense...
For example, my Max Velocity is 900, and I would like to make it so that it equals to the maximum of another Speed value at 14.
I tried to Divide the Velocity by about 90 but it messes up things when I move too fast.
@trim matrix what exactly are you trying to do? maybe MapRange can help?
I try to make 2 ranges following one another simply said.
yeah maprange or divide value by max value to get alphas
Oh I forgot about Alphas.
Maybe that's the solution.
can also use that for a lerp
Ok so it seems to work well, but I have to Interpolate because it still create jerks.
Certainy because the Velocity goes too fast.
This is with Divided but I have the same result with Map Range Clamped.
karmic hornet
Is there a way to override PostEditMove in blueprint?
trim matrix
@trim matrix possibly because you are directly influencing velocity instead of using AddMovementInput but not sure
This is how it's calculated.
Should I use Finterp To somewhere?
karmic hornet
Or at least where's the best place to bind an event? Don't really want to rebind it on construction script π
but it's for an editor function
so π€·
trim matrix
@trim matrix I don't think I should use the movement's Axis and such.
So I tried with my joystick's axis, it's the same, I have the jerks between speed change.
tulip iris
Can actors see what stream / map they are on?
I can manually get the streaming level but I want to know if an actor can see what stream its on without having to manually type it in
zealous moth
@trim matrix use movement states and transition between them instead of forcing the velocity
trim matrix
I don't really understand what you mean. I obviously can't use fixed variables for what I aim for.
Like Max Walk Speed itself.
zealous moth
Movement states dictate limits. I am not sure what you are trying to do but based on your bp and vid you want to shift your speed. No? States do that for you.
trim matrix
I'm using velocity to influence other values.
It's the same when I used joysticks axis as I said (which means a simple range from 0 to 1)
So the problem doesn't come from Velocity itself I suppose.

Anyone have any tips for using the search box in Blueprints? The documentation at https://docs.unrealengine.com/en-US/Engine/Blueprints/Search/index.html is pretty sparse and doesn't cover, for example, all the syntax I get when I do a normal search and press "Find in all Blueprints":
- There are names in brackets, e.g.
"(MyBlueprint)" - There are
=+signs, e.g.MemberName=+"Something" - You seem to be able to search by
MemberGuidand other properties of, say, aVariableReferencebut not others?
Ideally I'd like to search for all BPs that have been deprecated so that I can get a picture of how much work there is to do replacing them across the whole project.
Also, is there any way to export the search results as plain text so that I can keep track of them outside the editor (like on a todo list etc.)?
tulip iris
What's the "OOP paradigm"? I just wanted certain Utility blue prints to be active if their given stream was active. I can do it manually via the stream name but I was hoping actors might be able to know the stream they reside on.
For convenience mostly
odd ember
it's a violation of how the system architecture works
like you should query actors of a level through the level itself
tulip iris
I gotcha
atomic salmon
@tulip iris you can do it but not with Blueprints afaik. Basically you need to get the bounds of all streaming levels and check within which one your actor is.
odd ember
yeah blueprints as well do not allow access to ULevel which holds the level actor list
tulip iris
Alrighty
