if i want to make a variable where i can put a class ( projectile) in
what in the name of that variable?
zealous moth
what class is your class?
you can either specify the class projectile whatever blueprint it is
if it's an actor, make it an actor class
or you can make it a general projectile class
mild pine
Hmm, anyone that could help me out a bit with setting the character hand to sway about a bit as I aim my gun?
Tried out the above, but the arm is just being derpy
zealous moth
You can include keys in your animation and modify it slightly
mild pine
Sadly I have no clue about how to animate, was hoping to solve it within the anim BP
zealous moth
I do not know either but keys set points during an animation to do things... for instance if you want it to move in a circular fashion instead of straight you can do that by adding 3 keys
mild pine
(For instance, I only want this effect to take place when the character's been holding the string of the bow for X amount of time)
trim matrix
What's the smoothest way to iterate x integers that are unique and randomly picked from a range
maiden wadi
@trim matrix Easiest way that comes to mind is to make a while loop based on the length of a set. Sets can't have duplicates. Add an integer selected from range to set while set length < desired number of random integers, convert to array, for each loop.
minor karma
me again, looking for moar help
quaint falcon
how do you get the index of a certain object in a Enum in unreal blueprint?
minor karma
well hopefully that image loads for others
i'm lookign to simplify this, by not having start or end overlap, but to simply check and see if contact is still happening with a given object
maiden wadi
Discord servers are a little fritzy at the moment. Images don't seem to be loading in any of the channels.

@maiden wadi someone suggested random shuffle array but still couldnt find a way to do it with RandRange without tracking the used indices to reject
i got 3 arrays, i basically use them to make a 3 column table, each row having 3 values that correspond with eachother, is there a trick to get double entries removed out of this "table"?
double entries meaning entries with all 3 values the same as another entry already in the table
i hope thats somewhat clear, not sure how to explain it
maiden wadi
@trim matrix Wait, are you just trying to get random numbers from a list, remove them from the list and then select different numbers from the list that the numbers have been removed from?
trim matrix
i suppose i could merge the 3 entries as a string and then get the indexes for all double entries from that
but maybe there is a better way?
rigid thistle
What is the most efficient way to block movement input from the player for a specific duration? He should still be able to look around and be able to move with external forces.
trim matrix
@maiden wadi sort of
not sure about the removing though
so far there are a few ways one could do it
- What you said, simply pick and remove from an array
- Do a random shuffle on an array and rejection sample with array of picked indices
- Do a set difference with all indices and used indices and randrange pick an index from the result
actually if i have to do arrays for it, the method to pick and remove would be the easiest
but i was hoping to sort of do it without an array and only a randrange
hm, how can i make a normal array unique? just with 2 loops? i think i recall a node specifically for this but cant find it
maiden wadi
@trim matrix What you're after seems like a great place to use a set of structs, if I'm understanding right.
trim matrix
@maiden wadi it would be the same, for 3 values this should be fine, but i found an example of what i wanna do
maiden wadi
@quaint falcon Not sure I understand the question. If I do, you can convert the enum to an integer.
quaint falcon
so i made i enum (fire,water,earth)
can i say like give me the index of fire
=0
water
=1
etc

Hey guys! so i am trying to hide / show the mouse cursor, and I do it through the - get player controller -> set show mouse cursor - > true. but for some reason when I do so my mouse seems to get stuck inside the borders of the ue4 scene, and cant get out of it. it seems to fix itself when I press left click. is there a way to fix it? or a different way to show the cursor?
ocean radish
@latent basin I think you have the issue that when you use PIE mode and you set enable cursor until you left click in the screen it doesn't have focus?
latent basin
ye, i think thats it @ocean radish, how do I fix that?
ocean radish
try it in standalone, you wont have the same issue
not sure there is a way round it
latent basin
what do you mean? what is PIE mode?
ocean radish
play in editor
ocean radish
nah dont package just click the arrow next to play and select standalone if you want to see
remember this wont really be an issue in a game, as you'll be loading up and clicking with all the menus and stuff anyway so when you get into the game this wont be an issue
latent basin
ye, you are right, ill try that, thx!!
na, that aint it, the same issue holds...
i can see that it switches between two different focuses, and that whenever i press left click it sets the focus to the correct one, how do I set the focus in the bp?

What's the proper way to handle multiple arrays of similar objects? For example, let's say I'm creating groups of similar actors, and I want to store those arrays for easy reference and modification later.

I think structure will be easy if i got it right @vocal urchin
vocal urchin
So I guess imagine if you had control groups in an RTS, you could set all those distinct groups of units and store them in a struct?
What kind of struct would that be?
Cause it doesn't look like I can actually add an array to a struct...
Or would it be easier to just take the units in the array and put them in a struct, and have multiple structs for my unit groups?

Hello guys, i'm trying to make my pawn Jump towards location with BP, the "Jump" on the image is taking place, also the node after "add movement input" that changes the value of a variable is taking place so the nodes are working, but the character jumps only in place (no forward movement), What might be the issue?
worthy frost
you cant do that
you need to add a force forward
better to use Launch
over jump

Waht do you mean a force forward @worthy frost
dry pewter
Alright that node will do, now i just need to find the vector i want to be using, thanks

when using async save game is there any way to get the progress of the save. For example with bigger levels it takes longer to save

Maybe a delay in time before the saving takes place, and make the delay a variable that increases with level?
turbid valley
How hard would it be to make physic objects sync in multiplayer? I am testing with Network Multiplayer Fundamentals
opal pendant
@turbid valley first of all ask in #multiplayer second of all it's really painful to get physics working correctly
at least in my experience
turbid valley
Hmm
opal pendant
I would just stay away from physics if you're making a multiplayer game unless it's an important game mechanic
turbid valley
Well it is kind of
opal pendant
are you trying to use dedicated servers or listen servers? I think (someone correct me if I'm wrong) listen servers handle physics a lot better
turbid valley
Well i tested with dedicated server in editor
opal pendant
which one do you plan on using for release?
actually let me rephrase the first question: how many people do you want to be able to play together?
in one server
turbid valley
It will be some kind of "party" game where you can play with one or two friends
azure shoal
you will need to implement deterministic lockstep if you want to do physics in multiplayer
or at the very least you'd need deterministic physics
but, both of those are problematic to implement for a variety of reasons
turbid valley
My idea is to have items you can drag around with mouse
azure shoal
floating point determinism is going to be the first thing that will give you endless amounts of grief
turbid valley
Btw sorry for typos i am on my phone 🙄
azure shoal
what platforms were you targeting btw?
turbid valley
Pc
azure shoal
just Windows?
turbid valley
Yeah for now
But before i start i want to make sure few things like physics and other stuff but for now physics are my biggest problem
azure shoal
you will need to make sure you do 64-bit builds only, and make sure there are no x87 FPU instructions in your build
you will probably need to build unreal engine from source to verify the compiler flags are correct for that
turbid valley
Mm
azure shoal
and then after you've dealt with that, you'll need to deal with any non-determinism UE4 might have in it's physics engine
turbid valley
Well witch one is better for multiplayer physics ue4 or unity?
azure shoal
oh and then you will need to do deterministic lockstep on top - deterministic physics isn't enough since you need all the physics objects to be in sync with one another so the final result is deterministic
neither
multiplayer physics tends to in the realm of "roll your own" but either way it's very hard
turbid valley
Ok
azure shoal
oh
and you will probably need to update UE4's math library as well
from memory on Win64 it uses some SSE2 instructions that are not deterministic
turbid valley
Well seems like its a big no for mp physics for me. Maybe i could make some kind of picking up system so i don't need to have physic objects

@silk bluff world static is just something that you don't want to ever move in the world (i.e. a building) and world dynamic is something that you want that is a part of the world and moves (i.e. a crane or ferris wheel or door)
fierce birch
hey everyone, idk what i did but i really made a mistake. i was trying to do something with a camera then a few minutes later i see the mistake. when i hit a key to move the character, both the character and the camera flip 180 degrees, the character should flip 180 degrees but the camera shouldn't. The error is not in rotation under the camera as that is turned off. if anyone can help that would be very appreciated
this is what it looks like
trying to get help but no one knows what is causing it
fierce birch
i compared my blueprint set up to a new project blueprint and everything was the same
one sec ill send it
its the default 2d sidescroller setup basically
i think that the camera is tide into the a key somehow
The rotation under pawn is all off under camera
opal pendant
I would test out making the camera rotate -180 degrees when the character flips around because since the camera is a part of the character, when the character flips around so does the camera, but to the camera it's still in the same relative rotation to the character
so if you force the camera to rotate the opposite direction it will counteract the rotation of the character
fierce birch
Ok, how would I set that up so when I press that specific key it will do that
zealous moth
you could also dissociate the camera from the pawn
and if needed, re-associate
if your camera has a boom, make it not inherit rotations
fierce birch
I’m kinda new to this so could you walk me through your thought process if you don’t mind @zealous moth
dusty snow
zealous moth
i dunno what you want to make but based on the last paragraph i read here, it sounds that you want your character to do 1 thing and your camera to do another. I am going to guess you camera is linked to your character.
So you can either
- dissociate your camera from your character and have the camera do whatever it should do regardless of the character (you can set that up in your player controller)
- if you camera has a boom, make it not inherit rotations and keep it on your character.
If any of the things I said sound foreign, google UE4 + keyword. I know youtube has a greate series on WTF is <something> that can help you out.
fierce birch
I type in rotations on the detail panel?
zealous moth
look for "inherit" in the "camera boom"
fierce birch
Ok hopefully it works
The world blinks In and out
I deselected inherit yaw
But that makes my character not flip directions @zealous moth
zealous moth
yeah without seeing your bps, i have no idea what you are doing. Remember, I cannot see your screen.
zealous moth
ok, make it not inherit..
dusty snow
nevermind i figured it out
fierce birch
I did for all of them, but when I move the world blinks in and out. This whole problem started because I followed a wtf series
I’m so frustrated idk what to do
dry pewter
Hey guys, i have a setup on my character's blueprint, and i need it to trigger when the player clicks one button on a widget
How can i do that?
@fierce birch I missed earlier what was the issue?
fierce birch
I have two keys that control the characters movement, left and right. When I hit the akey(to go left) the camera flips 180 degrees, scroll up to see the video @dry pewter
dry pewter
On your chaacter blueprint
Is the camera boom (Spring arm component) attached to the root, or is it attached to the paper2D?
you can see that here:
If it looks like mine, then the camera boomk is attached to the capsule component
If that's your case then make sure you are rotating only the Paper2D component 180°, not the character (whole actor)
BC if you rotate the whole think the camerra boom and the cammera attached to it will rotate too since they are attached to it's components
thing*
one sec ill send it
@fierce birch In this setup that looks a bit difficult as you are setting the control rotation Yaw to -180 , you might rotate the spring arm component first, then set the control rotation
fierce birch
I put my camera under the capsule component
dry pewter
@fierce birch try like this
fierce birch
Ok I’m not at the computer rn but this should solve the problem?
dry pewter
It might, can't tell it without testing
fierce birch
Isn’t the 2d character always in 180 degrees?
Because when you rotate it -180 it faces left
trim matrix
man i cannot seem to simply get a variable from another BP actor of the same class, it seems to just return random stuff, i cannot find any logic in it
worthy pendant
Is there a simple way of selling from a hit result if the hit component is a skeletal mesh? Not any one in particular, just if it is one at all
trim matrix
i casted to my BP actor type, then searched for my variable name to get it, what could this problem be?
trim matrix
@worthy pendant it is
worthy pendant
So you are getting the variable to come up, but it's output seems random?
Is that correct
trim matrix
yep, cant find any logic in it at all
worthy pendant
Go into the bp you're trying to pull the variable and set up a print string on tick for the variable, with a duration of 0.0001
That way the variable's value will be present on screen at all times
that way you can verify if it really is just spitting out random numbers
trim matrix
i can see the variable name in the editor, it does not change or anything like that
i mean the values
worthy pendant
Then by the sounds of it there's something going on involving information you havent given us
Based on everything you've said thus far, it should be working imo
trim matrix
yeah its really really weird
dry pewter
Isn’t the 2d character always in 180 degrees?
@fierce birch can't tell for sure
@trim matrix As i explained the other day, the best handler i've found for this is makeing your variable "global" with a copy on the gamemode blueprint
trim matrix
its certainly something with the cast or around it, before the cast the values are perfectly sane, i just tested that, at least im getting somewhere 🙂
trim matrix
@dry pewter this is not possible in my case, i need to have it in the actor, because its simply part of the actor
dry pewter
Can you put a screenshot of your "cast to" node?
You can try making sure your "cast to" is not failing, in the "on cast failed" output print a string with "failed cast" or something
daring cradle
Could I DM someone about a blueprints question? I don't want to clog this chat but I need some help :v
I'm an unreal beginner so...the answer is probably pretty simple and im overcomplicating things
dry pewter
Sure
trim matrix
@dry pewter its just a Dynamic Cast
@dry pewter ill see if it fails thanks, i actually didnt test that yet
dry pewter
Aye
trim matrix
doesnt fail
could it be a problem that it is the same BP actor (different instance of course)?
@dry pewter
haughty axle
guys me again 🙂 question, when i doing timeline in blueprint, and add my track to components location vector+vector and then go to play it, it just disappears , but it i dont add them it works fine but starts from middle of BP
trim matrix
because i do something similar in another BP actor and that works absolutely fine
dry pewter
@trim matrix When there are more than one kind of actor on the map it's hard to tell where the blueprint will take the variable-value from, you gotta point exactly to the actor you want to read
trim matrix
@dry pewter thats what im doing, im not searching for it or anything like that
haughty axle
here idk whats wrong
trim matrix
but it must have something to do with this im almost sure, its the only thing i can think of, i didnt realize before this could have something to do with it
dry pewter
@trim matrix Can you put a screenshot?
trim matrix
@dry pewter i think it would make things more confusing tbh
its just a BP actor that has one variable, and i want to access that variable from the same BP actor, but a different instance
i got a bunch of these in my level, and i need to read the variable from another one
dry pewter
Different instance, like there are 2 copies of that ctor on the same map?
Or the same actor in 2 different maps?
trim matrix
@dry pewter yeah exactly, its the same actor dragged in twice (more, but twice to keep things simple)
dry pewter
on 1 only level/map
dry pewter
What i would do then, is have a variable in the actor and use it as it's index/name
then a "get all actors of class" with a "for each loop" that compares that index/name on a "branch", when the comparision gives a true then read the variable of that loop's index
trim matrix
@dry pewter the variable is an array of actor object references, im not sure what you mean by using it as its index 😒
dry pewter
You have 3 actors with the variable you want to read, let's call it "MyVariable"
But those 3 actors also have an INT variable called "MyIndex"
When spawn, each actor is given a "MyIndex" value that is the same as the previously spawned copy +1
So you can point exactly at each copy, to read the "MyVariable" value exactly from the copy you need to read it
trim matrix
that just complicates things for no reason tbh
the IDs are unique, so no index required
trim matrix
@dry pewter K2Node Dynamic Cast -> Get MyVar
i might just try to write them all, but that would make things a lot less elegant imho
@trim matrix Equal (string)
drag it off and press = or type equal
np
dry pewter
@trim matrix uhm i think im not familiar enough with dynamic casting
trim matrix
@dry pewter its pretty useful, but i am clearly not familiar enough with it either lol
@trim matrix you might be able to use a branch
@trim matrix that will take a bool as input, and you get an exec output for true and one for false
@trim matrix its annoying and hard to find all the right nodes in the beginning thats all
i have multiple actor references of the same class, im having trouble reading a variable from B with A so to speak, what could cause this? the output seems to not make any sense
dry pewter
why are you using dynamic cast and not regular cast?
trim matrix
if i try the same from another actor, with a different class, it seems to work alright
dry pewter
At wich point do you need to read the variable from A in B? @trim matrix
trim matrix
@dry pewter at start, and only once
dry pewter
Are you sure a screenshot is not helpful?
@trim matrix should be what you just posted in the image above, just dragon from the "TRUE" to the "make http call"
trim matrix
@trim matrix those white nodes define the order of execution
just use more branches i guess
or write C++ if you are used to normal coding
you can do everything in C++ i'm fairly sure
dry pewter
@trim matrix Can you tell me the sequence you are trying to do? so i can understand better the topic
trim matrix
@trim matrix yeah its nice to know both imho
i just wish there were more small examples that are easy to find, that would help a LOT
@dry pewter well still just reading a var from actor B with actor A, both actors having the same class, and are in the same level
@dry pewter actor C is of a different class, and it works fine in there, strangely
meaning if i use actor C to read the var from A or B
dry pewter
What triggers the "reading variable from actor A" on actor B?
trim matrix
@dry pewter just event beginplay
@dry pewter with the working C as well, for completeness sakes
dry pewter
If both actors are the same, then on event begind play, both actors have the same default value on such variable
don't they?
trim matrix
@dry pewter no, this variable can be edited, and i did that by hand
@dry pewter its "public and editable on each instance of this class"
dry pewter
aye
trim matrix
well each instance of this blueprint is what it says
@trim matrix just compare them, like before
same method just different data type
@trim matrix so just drag off, type =
dry pewter
@trim matrix
trim matrix
youll find equal (boolean)
oh yeah use AND lol
not equal
equal would work when both are false too 😄
dry pewter
use the setup on the image
@trim matrix and from the TRUE drag to the make http call, and form the FALSE drag to the error message you want
trim matrix
well use the other 2 branches if you want seperate messages
keep in mind security though in case it matters for your usage, not sure that is a good way to handle a password
dry pewter
@trim matrix
@trim matrix see the image, it does not use a "cast to" to avoid shenanigans
just searches for other actors of the same class, and reads their variable, in the example the variable is ID
so i'm taking the ID value from actor A and placing it on ID value of actor B
trim matrix
@dry pewter cant use that, i need recursion
dry pewter
@trim matrix here
@trim matrix Then you might do an awway with the results from each object in the loop
trim matrix
@dry pewter not sure what you even mean, but i need recursion as in: i get the first array, use those values to get more arrays, and so on
dry pewter
@trim matrix i meant this
trim matrix
@dry pewter either i dont understand you or you dont understand me lol
dry pewter
or both
trim matrix
haha
trim matrix
yeah but i need recursion so i cnanot just get all actors of class
dry pewter
And E from D, and F from E, and so on?
trim matrix
A reads the array stored in B, the array will point at several new objects, lets say C and D
just using ABCD in that order because of simplicity
its more like a tree basically
but obviously all my logic wont work if it outputs random gibberish lol
dry pewter
sound's like a messy cluster of data
trim matrix
exactly, but with recursion its elegant
every actor has exactly the data it needs and nothing more, is the end result if it didnt output random crap
drag the on clicked to the top branch, then the true from the top branch to the bottom branch, then that true to the third branch
@trim matrix ^
yep, and the stuff that is hooked to the data inputs just gets executed before the branch automagically
you can decorate it and add comments
if you think that is spaghetti you're in for a surprise in the future :-p
@dry pewter in fact its such a messy cluster of data that i could not even store it any other way lol
dry pewter
i think like this @trim matrix
also use something called "add reroute node" to organize the lines, it's wonderfull
alright Ed, your project sounds fancy and interesting, but harsh
vocal urchin
I am trying to draw debug points that stay at relative points around the character, and for some reason, I am having a ton of issues getting them to stay in the relative locations. What brain fart am I having with these vector maths?
dry pewter
@trim matrix Here's some spagetti on a tiny part of my project
trim matrix
@dry pewter i'll try to remember showing it when it works
i printed the values before and after the cast now and its literally something different after casting 😄
dry pewter
@trim matrix I still think having some kind of "index" on your actors would make it easier to read from each of them
trim matrix
its like i'm halucinating
@dry pewter because of the recursion it only makes it more complex then anything, i dont have to deal with the names basically
dry pewter
@trim matrix like so
in my example it's a string, you should use an INT number
and do the math to read each time what you need
trim matrix
@dry pewter yeah i get what you mean but it really wont help me (but i get that it would if i did not use recursion)
i just read the next one every single time, but that is not always just index +1, in fact that will be very rare
dry pewter
It's always "the next one"? that might help with a different focus
having the loop on an actor that does not have the data and is used only to move data from the previous actor to the next one
it's so late and i haven't found solution to my own issue SMH
trim matrix
@dry pewter well great timing, i get why it seems gibberish now..... i finally found the logic and understand what is going on
dry pewter
So you good?
trim matrix
@dry pewter yep its making sense now, my brain needed rewiring, not the blueprint 😄
@dry pewter what was your issue again?
dry pewter
I have a pawn being launched towards location, that set's a variable that triggers one animation, then when it reaches location the variable value is changed to trigger a different animation
Like flying-landing stuff
I don't know how to make my nodes to "wait untill locations is=something" so the variable is changed again
trim matrix
maybe an event on the "landing zone" ?
dry pewter
maybe an event on the "landing zone" ?
@trim matrix Uhmmm maybe, but sound's mesys to do in my particular case
messy
dry pewter
They won't overlap as they are bot skelletal meshes that are not block each other
both*
that will block each other**
trim matrix
the pawn wont overlap with the landing zone? 😒
if you have to you could even get the distance, theres many ways to do this
with distance you could even animate a landing as you get close, before you land
vocal urchin
Anyone know how I can keep those two debug points in place relative to the character's rotation? Not sure what I'm doing wrong
dry pewter
@trim matrix The thinkg is the landing zone is another moving character
But i found a workaround after many many tries
@vocal urchin isn't the duration toooo short? ont eh draw debug point node
vocal urchin
nah, it's on event tick
It draws consistently. This is all for visualization temporarily.
I've done plenty of character line traces outward from a point, but for some reason I can't figure this out when there isn't a start and stop point
The weird thing is switching it to relative rotation doesn't fix the issue
dry pewter
Are you using "get forward vector" correctly @vocal urchin ?
If those points are static i don't think that node is useful
static relative to character, i mean
vocal urchin
Yeah, they're static relative to character. Well, supposed to be 😛
dry pewter
just gat actor location, make 2 vectors at character location + offset, and draw the debugs there
get a reference to self > get actor location > make vector
vocal urchin
Yes, they're moving, but I need them to stay relative to direction.
So, if they character moves, they turn with it
Sorry if I was not clear.

Hi everyone , has anyone use Ryan Laley tutorial from youtube Unreal Engine 4 Tutorial - Minimap (Advanced) - Part 5 - Big Map and managed to bring the Points of intrest to the big map?I am trying for the past 2 days no result.Thank you very much in advance!
@tribal hill That's oddly specific! sorry, no
Not camera rotation, actor rotation.
@vocal urchin lemme think about it
vocal urchin
Ok, cool. Thanks for the help
tribal hill
No problem @dry pewter ! I hope that someone has:p.
dry pewter
Does it have to be debug points? because you could put 2 statich meshes on the character
vocal urchin
Yeah, won't have a use for actors in this
Needs to be vector points that I'm able to find for other actions
I'd rather not spawn actors for that if I can avoid it
dry pewter
Man it's hard
dry pewter
because when you make them appear they can't be moved
So calculating X/Y vectors based on character's rotation is kind of hard
If you spawn actors at player's location + X/Y offset, then move them based on caracters rotation it's different
vocal urchin
eh, yeah, but I really don't want to have to spawn actors for this. I'd like for it to be all math
dry pewter
You could have 2 invisible meshes as your character's component
then get component location, and draw the debug points at cuch location
vocal urchin
eh...but it's more actors lol
I'm doing these two as a test. It could be as many as 16
vocal urchin
Hmm, I guess so.
It's just a really messy way for me to do this, because I need to be able to move all these points on the fly dynamically
I don't want to do that with components.
I thought about doing line traces...but then I have to line trace 😛
So, 16 constant line traces on event tick...idk, seems unecessary
dry pewter
the components are there only to give you the location
so you get a vector to draw the debug points
vocal urchin
I know, but I need to move the locations of the points dynamically under certain circumstances
dry pewter
you still can do that
vocal urchin
Yes, but I don't want to do it with components if I can avoid it.

This is for an RTS unit formation. I'll have hundreds of components in the actor by the time I'm done
@vocal urchin I see
vocal urchin
Yeah, sorry. Not being obstinate, it's just that using components will not work 😄
as you probably understand now
I might just wind up doing this through line tracing
I think it will be easier in the long run
Cause in retrospect, I don't need this to run constantly
So, nevermind. Sorry 😛
dry pewter
@vocal urchin alright
@vast lion did you drag the "set static mesh" node from the "target static mesh"?
vast lion
@dry pewter Not sure what you mean. It's been dragged from the static mesh component.
dry pewter
what do you mean "fail2 in the first place?
it's not spawning, it's spawning but the mesh is not being set?
This worked for me
Well, bedtime, hope you find your answer

hi sorry if isnt right place for my question
im trying to mod a unreal game
my question is can i make a patch/mod for original-bigfile.pak?
seems like this game supprt mod folder
how can i add my file into a mod?
fallen glade
Does anyone know if you can know when the game has lost focus using blueprint ? Say alt-tabbling to another app
gloomy linden
@dusk prairie is the game you want to mod open-source or do you have its project files?
@fallen glade if you look at your task bar, you'll see the icon of the application in focus being highlighted
dusk prairie
@dusk prairie is the game you want to mod open-source or do you have its project files?
i only have unpacked pak file
gloomy linden
pak file as in from android?
fallen glade
@gloomy linden I mean from the game. I'm trying to pause it if the player is doing something else
so to know if the game window is being used or not
gloomy linden
fallen glade
so no ... oh well, rama to the rescue, thanks @gloomy linden
dusk prairie
pak file as in from android?
no from window platform
im talking about The Sinking City game
i see some game working with Mods folder (for exampel i see gal*gun use mods folder to apply mod to origianl pak file)
also this game doesnt use any encrypt key for pak file
gloomy linden
@dusk prairie well, unless the dev made the game modable, there is not much you can do
dusk prairie
@dusk prairie well, unless the dev made the game modable, there is not much you can do
when i make a folder name mods beside big pak file
and then copy some random pak file in it game detect new pak file but give me a error
gloomy linden
Not all games are made with modding in mind, the developer has actually stuff to do to make mods work
dusk prairie
i think this game supprt this stuff
do you have any guide to make mod?
Because if game didn't support it, geme wouldn't recognize the mod folder at all
gloomy linden
what doesnt work?
maiden wadi
@quaint falcon Is it not moving? Is it not turning? Is it moving too fast to update it's rotation to target? What is it doing? All we see is you setting a target and telling it that it's a homing projectile.

so without that part when i fire ..a red ball just spawns and goes forward
homing part doesnt change anything about that behaviour

Is it possible to actually replicate a blueprint defined delegate? (event dispatcher) I can see there are options on the detaisl panel, but i guess they are inert.
viscid valve
This is one of my big frustrations with BP and probably just a lack of understanding on my part of how debugging works - why do I seem unable to observe certain values when watching them and breaking code?
I try breaking before this node and on it, same result
maiden wadi
@viscid valve I don't think that you will see that variable update until after the decrement breakpoint.
viscid valve
Of course, but I get "no debug data" full stop
quaint falcon
how do you make a function that returns something in unreal like in c#
i wanna make a funtion that returns a bool
viscid valve
So you see the functions section of the blueprint screen?
Left side of the screen, in the "My Blueprint" section
You can add a new function, double click the new function you created
Now over on the right side of the screen under the "details" section, there is an "outputs" sub section
If you click the +, a return node will be added
You can then choose the datatype. Bool is default @quaint falcon
quaint falcon
thx a lot!
maiden wadi
@viscid valve Ah, I see what you mean now. Doesn't ever seem to work on the outgoing, but watching the incoming integer seems to update fine.
viscid valve
eugh I don't know why this stuff is so finnicky in BP
coarse patrol
Sooo, how would one translate this angular velocity to local space? I'm still getting variance depending on the direction the actor is pointing with transforming the direction with the actors world transform and by multiplying it by its rotation as well.
glacial eagle
Inverse Transform Vector and use the actors transform.
coarse patrol
Awesome! It works now, thank you!
maiden wadi
@viscid valve I can't be certain, but I think this might be because of the use of the LocalInteger inside of ManipulateIntInternal. It can't seem to read the output from that macro.
viscid valve
roooight okay. I can print them at least, just seems very odd I'm able to print the values but not view them in the debugging window... It's like debugging on Arduino with printf all over again hahaha
maiden wadi
I'm dirty. I rarely use the breakpoints unless it's something complicated. Too used to using print nodes.
viscid valve
I'm really used to using breakpoints now with other programming flows, even using hardware debuggers with microcontrollers, it's not the most reliable thing in the world, but it's more reliable than debugging in BP....
Fuck me sideways, now I remember that if you try and debug a list entry it crashes the editor REEEEEEEEEE
I tried to make a bug report but the bug report page I went to was broken...
So the impression I'm getting with BP for debugging is... print everything hahahaha
maiden wadi
So, I have a projectile actor that was working earlier. And now I can't seem to get it to collide with anything. It has a sphere collision and a static mesh, for testing I even tried putting both to BlockAll, BlockAllDynamic, tried a few custom collisions, but neither the Event Hit for the entire Actor, or either the static mesh or sphere collision fires. Overlaps don't fire, and this is against anything from a block all landscape, to skeletal meshes, static meshes, all with working collision. It's like my projectile is just ignoring the world suddenly.
False alarm. Turns out you can't put projectile collisions as children of a scene component apparently. Lesson learned.
viscid valve
The mind fuckery continues
Grabbing number of items from my list view; it works in one tree of nodes, but in another, it doesn't!?!?!?
Utterly bizarre
urban salmon
Correct russbo, print everything. I’m honestly still surprised that there’s no hotkey for the print node.
Also use append to make your print node more specific, otherwise you may spend a while tracking it down weeks later 🙂
I actually love the live view and watching the nodes execute for trouble shooting flow.
viscid valve
Yeah I have used appends before with printing, just lazy hahahaha
Yeah the live view is great... when it works
Honestly this is screwing with my mind
4 items in my list view, but Num Items returns 0
But in other places it works

now....
in every child projectile i filled in these vars
so every child has other values
now im in my character script
and i want to acces what i filled in into the 1 child
i tried it
how do i acces the values i filled in into for example the first child
so the 0 index in the highlighted array???
wild moth
if you want the default values of a classe's variables, ie not an instance, then use Get Class Defaults
So you don't have to cast it
if it is an instance, then you should cast it to the parent and get the variable

Hi everyone
Is it possible to make portal gate spawn in random places behind the third person character and after the sword projectile is out of it,it will disappear?Like i pressed X then a portal gate is spawned behind my third person character and after the sword projectile is shot it will disappear.And if i press X more than 1 time in 5 seconds it will spawn the number of times i pressed X and spawn separate gates equal to the number of times i pressed X in those 5 seconds.
can anyone tell me or gimme some advice on how i can make it work?
quaint falcon
@wild moth i dont want the values i put in into the child like i showed
how do i get that?
wild moth
You want the values you set in the child classes?
Like I said use GetClassDefaults
from the array
quaint falcon
but i dont want the defaults? i dont get it
wild moth
the defaults are the values in the class, ie not anything that was modified by an instance
you'll get the child classe's values
hardy ibex
@wild moth can u gimme some advice on my project as well?
wild moth
I'm sorry @hardy ibex I am working as well and yours is a bit more complicated

so just to be clear.. when i have a parent brick with a public variable named "bruh" (default value = 1).. i make a child blueprint of that one.. open it and change the value of bruh to 6 in the child.... ik i use your method will i get 1 or 6 back?
hardy ibex
It would be great help
wild moth
You will get 6 @quaint falcon because you're getting the default class values of Bruh
quaint falcon
aight imma try it

vocal urchin
Struggled with this last night, thought I found a workaround, and now struggling with it again...how do I align the debug points (visualization for later) along the axis with the original line trace? Currently, they're just being projected in the world a set distance from the trace end, but I need them to remain relative and aligned.
Current code
Here's what I'm trying to achieve, in case I didn't explain it well
mild ore
i'd do something like normalize the trace end-start, then call it a forward vector. from this result get the rotation using rot from x vec and then rotate vector all those four relative vectors you use. just add the resulting rotated vectors it should be aligned.
if i understand the problem correctly
vocal urchin
@mild ore I'll give it a shot. Might flub it up on the blueprints, but I'll post what I have.
Like that? That seems to bundle all the points into one.
mild ore
no. you got 4 relative vectors specified in your previous screenshot (the 4 additions). You must use the rotatevector() node to rotate all of them individually. you'll basically copy the vector(500,500,0) into the rotate vector's field. these still going to be relative vectors but aligned, so as a final step you will add the pivot point to all four, again individually. The resulting vectors are your world points you can debug print above.

sour raft
Is it possible to turn off occlusion for a scenecapture2d? im trying to get it to capture 'behind' objects, but they're fully occluded and not being rendered
mild ore
its possible to override the scenecomp in cpp and set a near clip far away enough, so it will ignore nearby objects in rendering
sour raft
i need the clip plane to stay where it is, im manually adding them to the hidden actor lists
vocal urchin
@mild ore This is as close as I've gotten, but when I move it around the character, the debug points move too much and get away from the axis of the original trace. But, they are semi-relative now.
What's the right way to use the trace start? Do I add or multiply with trace end?
sour raft
im hiding all objects that a traceline hits, in order to see 'behind' them, but i still need to see some things that are closer (so clipplane trickery wont work)
mild ore
Dave you dont rotate the world vector, you must rotate the relative vector. Basically disconnect the addition, dont use world location in there. instead add the world location after you rotated the relative vectors.
mild ore
@sour raft by modifying the scene capture, you will only set the near clip for the scenecap, it wont affect your main rendering scene. thats the idea. but i understand you may need a more complex occlusion hack, which probably is complicated since many traces going to cause huge cpu load.
sour raft
nah the capture itself needs to see everything, im trying to use it as a radar, so it traces a line straight down where the player is, hiding anything it hits (ceilings, floors above, etc) so that you're just left with seeing everything else (which may be high walls nearby and so on)
eg. in a standard room, it would set the floor and ceiling to hidden, but the 4 surrounding walls wouldnt get hidden, so you'd see the walls only from the scene capture
the problem is, if the ceiling fully occludes anything underneath, they arent being rendered at all (to the scene cap)
mild ore
these are complex rules, you're better off specifying them in the scene caps ignore list indeed. you will need however hide everything else in the main scene, so you'd setup a very close far clipping for the view in main render. Maybe you better off doing things the other way around and not messing too much with main renderer.
Idea is to set visibility of nearby objects hidden, and only render them in scene cap by specifiying the allowance list instead.
you'll probably have to deal with z order tho, the composite will be flawed i guess
vocal urchin
This is getting really good, but I get some weird rotation of the points as I move closer to the trace start. It's not 100% locked into position, which would be ideal.
sour raft
i dont think any of the hidden actor list options / visibility options is going to make the scenecapture 'see' things that are occluded though? or maybe im misunderstanding
mild ore
Dave, i have told you to normalize (end-start), not only the end.
sour raft
it seems that the scene capture is hiding objects out of view by default, then in addition to that, will look at the hidden actor list
vocal urchin
@mild ore Ah, good call. Thanks, that did the trick!
mild ore
@sour raft i dont think scene cap is hiding objects in main view if that's what you mean. more like you're rendering it on a plane that is occluding perhaps everything else. but you can make that plane to be non occluding geom it should allow things show up behind.
mild ore
the scene capture is starts as empty when you use an allowance list
sour raft
eg. scene capture behind a wall, add the wall as a hidden object, it wont capture objects behind that wall as they are occluded completely
in the same way that the main view wont render objects that are fully occluded
im basically needing to turn off primitive occlusion but only for the scene capture
im not sure the allowance list (basically inverting what im doing) would make it render objects it has no way of seeing due to occlusion?
mild ore
it will render them
basically you setup a new empty scene and populate only the relevant stuff, which is preferrably the nearby objects only
in main view you hide them temporarily
so main view will render everything else behind
sour raft
the main view doesnt need anything changing in this case, its just a matter of getting the scene capture to see the right things
ill try it this way around though, i havent yet approached it this way, i was using the hidden list instead
mild ore
if you render far objects in scene cap you end up populating a list of 1000s objects it is not a wise choice i think
you should try it the other way around and only deal with nearby objects
wild moth
Np 🙂 Just a tip, it's better visually to break the struct outside of the function and then hide unused variables
So it's cleaner
👍

Hello, I am creating a level sequence player which plays a level sequence which has "spawnables" in it. How do I get references to all these actors which are spawned by this player?
crystal mural
@low venture Would you be looking for "get all actors of class"?
onyx pawn
ok tried the code but no mater what its still printing the message, its like its ignoring the array and just printing as soon as player enters
maiden wadi
@low venture Get all Actors of Class like Glowbeard said works if you want all of the spawned actors in the level. If you just specifically want the actors spawned by that exact spawner, you need to keep an array of the spawned actors in the spawner.
onyx pawn
low venture
@crystal mural This would be a inefficient workaround... First "GetAllActorsOfClass" could be slow on large maps and second I don't know by which level sequence player the object was spawned if I have more than one level sequence player.

I have a Static mesh that I want to click to drag&drop around my map.
I want the mesh to stay within the square bounds of the gameplay area.
Inside the gameplay area everything works perfect.
When it hits the edge, it gets stuck if the mouse is still moving outside the area.
One fix I did is if the mesh hits the outside of gameplay area, then movement on that x or y axis is ignored, and the mouse cursor gets moved back to center of mesh.
This works somewhat ok, but it gets a little jittery.
Anyone know of a better solution or even anything that may help?

@onyx pawn That's asking if the actor that this actor just overlapped has three or more overlapping actors. Is that what you're trying to do, or ask if this actor has three or more actors overlapping?

here's a new one:
I am using the rmb to zoom in and out. On the first inputs for zooming in, the timeline and lerp work fine. On the second, it just doesn't do anything... and after a while it just skips the timeline entirely and intantly switches... Any ideas?
dry pewter
@stuck hedge This setup stores the level name on a variable when "9" is pressed. and opens that elvel when "8" is pressed
stuck hedge
I was looking more at a soft reference to the level file itself.
dry pewter
@stuck hedge Such variable should be in gamemode blueprint so it's value stays stored between level loads
I was looking more at a soft reference to the level file itself.
@stuck hedge Sorry i thought of level object reference
stuck hedge
Yeah, I want a reference to the file, not the name, so that if the file name is changed it'd be changed automatically elsewhere.

tired arrow
Hey so I've made a very simple portal which uses a scene capture 2d to render onto a material so that you can see the other portal's view. The only issue with this is that when the scene capture moves around to provide accurate depth, it can show unwanted objects, like in the second screenshot.
If anyone has any thoughts as how to make it not do that or make that object not visible in the render, that would be great!
dry pewter
@vocal urchin Doesn't seem to be working, i' trying to move my currently player possessed character
vocal urchin
Are you giving it a location to actually move to?
tired arrow
Yeah Dave I have these two nodes for the two portals adjusting their location relative to the player so that the depth matches up to the player's perception if it were a real portal
vocal urchin
oh, sorry, was replying to @dry pewter
tired arrow
Oh my bad sorry
vocal urchin
Have limited experience with scene 2d captures, but I'm curious why you're moving them. Why not just make them a part of the doors?
@tired arrow
dry pewter
Are you giving it a location to actually move to?
@vocal urchin Yeah it's the vector of other actor's location
vocal urchin
@dry pewter Not 100% sure what kind of behavior to expect when moving a player mesh/capsule using that node. It's great for AI, but that's all I've used it for.
Sorry
dry pewter
I think it's AI only, there's a node called "simple move to" but i ccan't make it work either 😦
tired arrow
Yeah so basically I move the scene capture so that when the player gets closer to the portal, it looks like you're getting closer to what is on the other side of it. Without that code, the scene would look fixed and unrealistic, as if you were entering a picture frame instead of a portal
tired arrow
Yes, so the camera that is attached to the other portal comes in closer when the player gets closer, and farther as they get farther, but this can cause issues if there are actors or walls behind the other portal

I just found under "Primitive Render Mode" an option that says "use showonly list" to render primitives
That might be promising but I need to find that list
vocal urchin
Yes, that's one way
tired arrow
The issue is now, if I choose to make the portals dynamic/moving, the player will be confronted with new objects when stepping through the portal that weren't shown before
dry pewter
@vocal urchin got the movement with the "simple move to" node, it required a "nav mesh volume" in the level that i did not have before
Thanks
vocal urchin
Ah, yep, that'll do it 🙂

Is there any way i can get a point location (vector) like a line starting at point A, pointing towards point B, who's lengt is X (ie 200 units) ?
Kind of solved it using a spring arm and invisible sphere on actor B
inner ginkgo
@dry pewter (Yellow Dot - Red Dot).Normalize() * 200
dry pewter
like this? @inner ginkgo
inner ginkgo
Yes. That gets you the vector you want relative to the red dot. If you are using relative operations, then use it as is. If you are using world space operations, add it to the red dot's location.
dry pewter
I want the red dot to move towards calculated point
using "simple move to location"
i think thats world space
inner ginkgo
I believe that is correct. So you'd want to add the red dots location to that math.
dry pewter
How so?
dry pewter
Right it's working under that logic
inner ginkgo
Excellent
dry pewter
Since i actually wanted the point to be calculated 200 units since yellow dot, i changed yellows and reds places
And works wonders, thanks a lot!
inner ginkgo
You bet.
dry pewter
Omg I've trying to complete this logic for 3 days
Now it's working ❤️
Thank you very much
inner ginkgo
No problem. I usually learn a lot when I'm working through issues for a long time. So it probably wasn't a wasted 3 days.
dry pewter
True that

Just curious, as I can't seem to find any information online about it
What's the difference between playing a sound, and spawning a sound?
They seem to do the exact same thing, haha
Only difference I've seen is that the node for spawning a sound has a return value?
dry pewter
As far as i know
"play" will trigger once, then delete it and do nothing else with that sound
"Spawn" will create a "invisible object (sound" in the level, with the return node you can do stuff, like playing again the sound when "something" happens
trim matrix
whats a good way to have an actor listen for messages from other actors? cant find much info on that, what shoudl i search for?
or a good way to detect a change in a variable
stuck hedge
You want to bind to delegates.
@trim matrix On the actor who will send the message, create a delegate, and call that delegate when you need others to listen. On the others who should be listening, have them pull off a reference to the first actor and "bind event to " that delegate that you created
trim matrix
@stuck hedge thanks ill take a look 🙂
stuck hedge
Sure, and if you need to pass any variables you can configure the delegate to take inputs and pass in those variables.
stuck hedge
That's fine, you can setup the variables the same as you can with any other function. Just set them on the delegate first then on the other actors you can either create an event or bind them to any function that has the same 3 inputs.
trim matrix
@stuck hedge is it a problem if its the same actor, but different instances (if that is the correct terminology) ?
i know this may sound weird, but i need recursion
stuck hedge
No, because you're binding to that specific instance.
trim matrix
perfect
stuck hedge
so if you had 2 light switches that were the same blueprint and you wanted to bind light switch B to the switch event on A, then you could do that. When A was switched, both would switch.
You might need some additional configuration, like a way to designate one switch as the master switch, and to tell the other switches how to find the master switch, but it would be fine.
trim matrix
after realising that normal impulse property on the hit event is not the actual velocity, a dot product is pretty effective to determine sliding on a surface
@stuck hedge but technically no master needed right?
stuck hedge
Technically not, no.
it really depends on what you're doing and how you want to set it up
trim matrix
ill have to start messing with it but im a little burnt out, maybe after some more coffee 🙂
but sounds like its what i need, also from looking at the docs
thanks again for the help @stuck hedge
stuck hedge
Any time.

Huh
Running into an issue rn
When I go to package a project, it's sending me to the UE4 doc when I press Win-64
trim matrix
@stuck hedge do you know if there is any way to specifically dispatch to one instance of an actor reference? if i understand correctly what i read everything that listens to it gets triggered right? i suppose i could send the id of the receiver that should get it and have a check on the receivers, but that does not seem ideal, maybe there is a better way?

Hello everyone 🙂
We encounter a weird bug in our game:
Collisions & traces are working at the beginning of a game, but after sometimes, they are not responding anymore (we can pass through buildings with collisions, linetraces & spheretrace are not responding anymore...). This bug seems to affect only an area of our map, not the entire map (the area is also random). With our research, the bug seems to affect only blueprints (no bug on foliage, landscape or static meshes).
The bug is present in multiplayer (but only on serverside, on clientside traces are working) but it is also present in solo..
Here is a video for the bug (clientside so you can see we can pass through buildings but the client resist a little due to collisions are present on clientside but not on serverside): https://www.youtube.com/watch?v=4U42qvaKAB8
We are stuck and searching to solve this bug for more than 3days..
Thanks for your answer!
maiden wadi
@onyx pawn That's an add node for a Map.
onyx pawn
so I look for Add node?
maiden wadi
If you wan an add node, yeah.
@noble wharf I'm not very well versed in multiplayer, but at some moments it almost looks like your client is behaving well and then getting server corrected, like the objects are lacking collision on the server, but have it on the client. Like around 23 seconds I think, the player jumps on a mesh, stands there solidly, and then gets 'corrected' down into it a moment later.
noble wharf
yes that is the problem! But this is very weird that the bug is not present at the beginning of a game and appear after.. It is also present in solo, i don't have any node that set "no collision" or anything :/ (sorry for my english^^)
maiden wadi
@dry pewter Are you still having trouble with the blackboard thing?
maiden wadi
@dry pewter I'm so confused by that blueprint. Are you trying to set one blackboard key from another blackboard key's actor location?
dry pewter
Basically i ave one blackboard key with "Actor A" value, on other key i wanto to set other blackboard key with "Actor A's location"
But the location being taken from the value stored on the previous Black board key
Any way to read a blabkboard key value from a Task or Service would help me
maiden wadi
Can you have two blackboards on an AI? I know you can change them, or keep one in a variable.
dry pewter
Uh no i mean
On the same blackboard i have multiple keys
One is "actor" and one is "vector"
I store a value on the Key that is "actor" kind
Then i want to read that key, then "get actor location" and store it on the key that is "vector" kind
maiden wadi
@dry pewter Try something like this.
dry pewter
I think the "make literal name" is what i was missing
maiden wadi
You can also use Selectors to get blackboard values, but I had a lot of issues with that when I first started on AI, and I got used to using the key names.
dry pewter
I managed to get both values if i get them on the same service
like this
wait i erased a line
Now what i'm stuck with is trying to make the behaviour tree select randomly if it runs a node or not
Left is move to a random location and right is move towards 1 random player (out of 4)
Each one works, tested
Now i need a way to make one or the other occur randomly
maiden wadi
You could put a decorator there to return false based on numbers. If you want it 50/50, get random int in range from 0-1, if 0 return false, if 1 return true.
dry pewter
I tried it but the number would always be 0

dry pewter

@maiden wadi How would you make this setup? what i've tried so far doesnt work
maiden wadi
This 'should' work.
Something like this works too if you wanted more of a difference in chance like 25% instead of 50%
If memory serves, you might also want to make that sequence right under the root a selector instead. I think that if your left move to fails, the whole thing will fail, where as if the left one fails with a selector, it'll move to the next in the list.

i dont really know where i should ask this question but i feel like its the right place to post it here. Is it possible to move the camera without moving the other componentes which are a child of the camera? I want the components to keep being a child of the camera but not follow the cmeras location.
dry pewter
@maiden wadi Alright thanks, will try that tomorrow, for now is long past bedtime, thankyou

@feral ice Some components have a "inherit pitch/roll/yaw" you can set to true or false, like the spring arm component, that might be what you are looking for? seting the inherit to false
stuck hedge
@trim matrix In that situation the actor that is doing the dispatching should have a reference to the one that it should activate and just talk to it directly rather than use a delegate. Delegates are for having an unknown number of listeners.

Hi, I'm working on an overcooked esque local co-op top-down game and I'm kind of stuck on the math for my player camera. I right now have made a temporary camera which simply tries to stay in the average position of the players but theres some obvious issues there already:
- It might not keep all players in view
- It does not adjust for height nicely
- If I angle my camera this approach will not work at all.
So would anyone know if there's any pre-documented methods of approaching a problem like this for an angled top-down camera?

@trim matrix I'm taking a stab in the dark here. But could you have the blueprint that has the camera swingarm calculate the distance between all your characters, and then based on the biggest number extend the camera swingarm?
@trim matrix I'm also sure there's a node that checks for the distance of something to the edge of your screen. I can't remember what that's called now.

@crystal mural I havn't heard of a node like the one you mention but I'll have a peek at that. A part of the issue is that if I angle the camera there'll be more on screen at the top and less at the bottom which I'm not sure how to combat

Simple question, i've got a float on a blueprint component, the variable is set to "replicated", condition "none". She is correctly updated on the server... but not replicated on clients, any trough ?
urban swan
Actor should be enabled for replication, as well as component containing said variable
Also they should be relevant for client to be replicated
zealous sundial
@urban swan thanks, it's working like this :
but just to be at 100% sure, cause when i read the doc, this said the whole component is replicated. I just want the variable health inside of this component, this is the correct thing to do ?
urban swan
Afaik, only properties marked as replicated gets replicated

@quaint portal I can't be sure, but from a video I was watching, it pretty much looks like a get results under cursor, if actor implements interface, set a local variable, on mouse x or y, if moved enough, send interface message to object to play open animation.

just make sure the pivot is on the right place in the model and have it track the mouse position once being near enough to interact with it
maybe add a clamp to make sure it cant rotate past a certain point
