You should normalize the vector output from the subtraction and use that instead. You have gotten a vector facing from the grenade to the hand but then you only use the world X from that.
lime gull
Wait goose, how do i make it so you can interact with the generator
Actually I could pobably fin a tutorial
fathom bridge
Are you attaching the grenade to a socket on the hand? Have you considered simply rotating the socket itself? On the skeleton asset
hoary pier
@lime gull That's however you want. If its on a keypress then ytou have to determine if the player is in front of/looking at something to interact with
lime gull
Do i have to set thek to interact with it inside the character itself?

Hey guys, I am sort of new to unreal engine and I was wondering - is there something like an "empty" component in UE? I need something with a transform to hold a few subcomponents and I have no idea what to use ..
fathom bridge
Yeah it's called a scene component
brave grove
@fathom bridge thank you but I need something with location and rotation ...
plush yew
A bilboard may be what you are looking for
fathom bridge
No a scene component
A SceneComponent has a transform and supports attachment, but has no rendering or collision capabilities. Useful as a 'dummy' component in the hierarchy to offset others.
That's a direct quote from here:
azure shore
ok I got my doomguy thing kinda working but its changing sprites based on player position rather than camera
fathom bridge
It's an empty

well, here's where the fun begins. my boss just said "hey can you port this project to Unreal?" we've been writing a thing in Unity for the last 5 months.
fathom bridge
omg..

i'm guessing this means that our demonstration was successful and that we have funding to carry on longer. 😄

You’re going to need quite a few coffee airdrops
fathom bridge
At least now you'll get to use the superior engine :p
heavy ether
right... well, i haven't really used Unreal since 4 was in alpha.. so.. weeee fun.
i'm wondering if we should grab one of the "use C# with Unreal" plugin thingees that i see exist to ease people's lives there
abstract relic
azure shore
ok this is weird I have 8 sprites one for each angle but only four of them face the camera, yet theyre all in the same script that sets them to face camera
can it only do four at once or something?

You are gonna wanna learn some of the conventions in unreal
I have a Udemy course on Unreal I just released; if you're interested, let me know.

What do i use for the objext of a widget when casting
abstract relic
And use live++ for heaven’s sake.
fathom bridge
What are you trying to cast from and to
DJ maybe four of them have local transforms in their BP

i thought unreal had live reloading.. is that not the case now?
abstract relic
It does but no one uses it for large projects. Not even Epic’s staff 😜
fathom bridge
Hot reloading? Yeah I don't use it
azure shore
._.
heavy ether
so, i'm guessing from a real quick google, that involves installing Live++ and github kitelightning/livepp ?

Nvm i got jt

i should probably download the latest version of the engine while i'm chatting about it

Wait
When removing a widget, how do you make it so the variable is alwayd savex
Cause it resets when I remove the widget
fathom bridge
You could just set its visibility to hidden instead of removing it

for some reason all the ones on the right are working fine but on the left they arent
lime gull
Alright lemme do thag
azure shore
I used two different set rotations to see if it would help
fathom bridge
It sounds like they might have different initial rotations
I don't think the node has a limit
fathom bridge
are Left, Right... etc Actors?
Can you open their blueprints and see their sprite component rotations
heavy ether
i think i need to see what's up with our assets. none of our assets were in the right orientation for Unity, so hopefully they'll all be good with Unreal. They're probalby like left-handed Z forward and right-handed Y forward or some crap. lol
abstract relic
The import menu gives you the option to rotate it regardless
heavy ether
😮 unreal rules

Making it hidden still resets it

heavy ether
well, it was only 4 months or so of dev work building it mostly between two of us, i'm pretty sure that i should be able to replicate it in a different engine, one i'm more familiar with, in less time.
although it is entirely possible that using Unreal will be like a completely foreign experience for me
i at least won't be spamming chats with things like "how the hell do i convert from world to local" and "who the hell thought spreading the rotation functions across 4 different classes was a good idea"
so, what other things are nice to have? considering c# and/or v8 plugins because all of our devs are pretty highly fluent in one or both, and our C++ experience is significantly less, although we're pretty flexible on that sort of thing
sage tree
So, I have a question, and its probably a pretty basic one but its driving me nuts, im importing some assets, and them moving them, so that my file structure is maintained, however it seems every time I do the references get messed up, what is the proper way to move files within UE4? Ive just been draging the asset to the folder I want and selecting move to.
fathom bridge
Maybe a C++ tutorial or 2. Like mine ;P
What you're doing should work. Selecting moveto should update those references
How are you importing them?
sage tree
using the marketplace
fathom bridge
Are you just opening the content folder in explorer or are you importing through the engine
sage tree
when I close the project and re-open it all of my assets are messed up, no textures etc.
fathom bridge
Oh I've gotten that sometimes
sage tree
its not osme times, its every time.
fathom bridge
I've gotten that from marketplace items. They reference folders in relation to their current folder or something
Even when I migrate to another project I've always been forced to just let them stay in their folder structure. It's really annoying
sage tree
Yeah, I really dont want that.
fathom bridge
Have you tried not moving to but instead choosing to make a copy
sage tree
No I havent, ill try that.
fathom bridge
see if that works, then maybe deleting the original folder and seeing if it still works
idk if it'll work
but worth a try
sage tree
yep
frosty bloom
You'll break all references 95% of the time if you just drag from a folder to another. Migrate option from within the content browser is what you want to do.
heavy ether
oh.. VS2017 is mandatory. huh.
frosty bloom
Regarding folder structure, once you change things within your project you might want to fix up redirectors
sage tree
Do you need to do that on each folder, or just the root?
frosty bloom
The root will do the trick
heavy ether
... will it also work with VS 2019?
frosty bloom
I think 4.22 and forward supports VS2019
dim plover
You migrate within the same project? The tooltip says it's for cross project copying. *nvm misread
frosty bloom
It is for cross project copying
heavy ether
whoa, the free version of VisualStudio has a checkbox to install Unreal Engine along with it. The developer world is an entirely different place than it was last time I used Unreal 😄
fathom bridge
He's just adding assets to his project from the marketplace then moving them
I think fixing the redirectors is what he needs to do
unborn fractal
Is there a way to cut down the parsing time for visual studios? Usually every time I open visual studios I have to wait roughly 10-15 minutes for it to parse the entire engine. I am currently using Visual assist which helps but its still a long time.
My CPU utilization is also at 100% while parsing. Currently have an I5-4690k.

It happens every time I restart my computer.... hmm...

I regret watching this tutorial series. While it helped understand some things, i still feel lost pretty much at every step of doing something. Still a lot to learn.
However im in a time cruch of 2/3 weeks to create a simple thing to present(vr game where you set up a tripod and walk to several points in the game world) and I thought it would be much simpler process.
I cant even set the camera to work, or import a vr character asset
I screwed myself basically
sage tree
Ok so I got it working, moved assets over using move to command, then did fix redirects on the root, checked files, restarted checked files, deleted marketplace folders, did fix redirects on root again, saved, reloaded the projects, all files are good. not sure what the direct process is, but its in there somewhere.

Whats better for unreal developemt and game development in general an i7-8700k or ryzen 7 2700x
manic pawn
https://cpu.userbenchmark.com/Compare/Intel-Core-i7-8700K-vs-AMD-Ryzen-7-2700X/3937vs3958 seems like the intel will be better in sc, so the editor and games overall will be faster with a lot of single threaded parts, but the ryzen is slightly better in extreme multicore loads (baking lights or compiling many files)

You shouldn't have a problem with either of those, assuming you have a decent amount of ram, good gpu and enough ssd space for unreal

this is one of the cases why people make the collision on stairs a flat plane up, you don't need stairs to be stairs most of the time just a ramp for collision

Hey all, just joined the discord
I have a question relating to if it would be possible to access data from an existing game. Specifically I'm wanting to make a client-side mod that sends game data to a mobile companion app, but if I'm honest I'm a systems developer and don't do much dabbling in game coding, any tips or direction on this would be most appreciated
silver crown
to access data from an existing game What kind of data?
harsh tiger
all get stuck on the stairs
swift jacinth
@silver crown such as current map of the game (it's an FPS) and possibly other data like players in the game, which side they're on, the score data, etc
silver crown
Which game?
swift jacinth
@silver crown The early access FPS called Squad
@silver crown I'm a huge fan of the game, it's really good so far, and they do support server side mods, however the client side stuff hasn't really been developed yet, which I suspect will be supported at some point, there are no APIs yet or any real way to get the data, so I'm wondering if there is a way using the UE4 API to get at the data somehow
swift jacinth
@silver crown Well there isn't a API yet, there are talks of one from what I've read. They do have server side support and I could make a server-side mod that would do what I want, but it would be up to the servers to load said mod for it to do anything, I would really prefer to develop it at the client level and let users decide if they want it or not
silver crown
I don't have much xp with mods sadly
swift jacinth
@silver crown It makes more sense considering it would need to be linked locally to a mobile device, then having some system for users to link the server to a mobile device etc
silver crown
definitely
swift jacinth
@silver crown Well I appreciate the input, so you think there is probably no way to get data like that using the UE4 API then?
@Phy I hate to trouble the guys working on Squad, I'm sure they are buried trying to get things done, and a client-side mod is probably low on their totem pole so to speak
fathom bridge
@swift jacinth are you familiar with Winsock
swift jacinth
@fathom bridge Quite a bit actually, that's more the stuff I deal with day to day
fathom bridge
Oh cool! Why don't you just open a socket and send it via a TCP packet to your other device
swift jacinth
@fathom bridge Are you referring to intercepting the packets and decoding the stream and interpolating the data to send to the mobile app?
fathom bridge
No, that's way too convoluted
Just gather the info you need in game and package it up into a packet and send it out
swift jacinth
@fathom bridge My rough idea was to have an app on for example an IOS device, listening for UDP data and have a PC running the linking application sending the data over the local network to the mobile app
@fathom bridge However the issue I have is getting the data from the game, I can do all of the aforementioned things except I have no data to send
fathom bridge
Oh if you're intercepting then yeah you'd need to decode it
swift jacinth
@fathom bridge Unless you happen to know of a way I can get the data out of the game without breaking anything. It does use EasyCheat and I'm pretty sure if I went about scrapping the screen or probing memory I'd probably piss it off
silver crown
Definitely lol
fathom bridge
Yeah what you're talking about is something I haven't done before
silver crown
Are there only server side mods with Squad?
swift jacinth
I mean there is a 3rd party website squad-servers.com that has some of this similar data, but not data from the server itself, but more from the listing of the servers, nothing about players or player data etc
@silver crown There are quite a few, different game modes, lots of things, it's actually kind of surprising given the game is still in early access alpha development
silver crown
Seems there're all server side
This is to ensure fair play, as well as version syncing. For example, if you were to retexture a player model, what is to prevent someone from making all players bright pink, so they stand out? However, if it's applied to the server, then everyone would be bright pink... making such a mod silly and the advantage moot.
So I guess you're doomed to install it on the servers 😉
swift jacinth
@silver crown Hmm interesting, yeah I'm not trying to do anything to tip the scales for any players, just a way for them to have for example a map screen on an iPad they can glance over at while they play instead of pressing M and looking at the map, very helpful if you're doing fire support or planning a fire mission
Maybe it will just have to be server-side, which wouldn't be a huge deal, I see the logic in not support client-side mods for that reason
fathom bridge
isn't that tipping the scales though? :p
swift jacinth
However that will mean to develop the app I will need to run a test server
@fathom bridge Well it only shows data that you would already have
swift jacinth
Everyone can pull up the map in game and see markers where teammates are etc
@silver crown No servers are available to download and run privately if you choose
silver crown
Yeah so no big deal 😛
fathom bridge
Yes but with what you're doing they would be able to see it without having to do that, a tiny step eliminated.. giving them the slightest of edges
swift jacinth
It just made much more sense to me to have the mod client-side since the users would be linking it to a mobile device, I'm not even sure if a server-side mod could do that, maybe via a website, so server-mod links to a API like website and you would somehow link the app with your player and then the server could feed the data, way more overhead and work involved
oblique sorrel
So, I got logged out of forums.unrealengine.com, Firefox somehow didn't save my login credentials, and I can't recover the password 'cause the password recovery page is just
What do?
swift jacinth
@fathom bridge possibly, but I think looking away from the screen to something like an iPad would be about the same as stopping somewhere and pressing M, the map overlays on the screen so you can still see what's around you etc
fathom bridge
Sure, possibly. But the point is that its different. I'm not judging I'm just saying it is a change to the game
If you have good peripheral vision or put it next to the screen you no longer havr to press M
Its an advantage other players don't have
But again not judging
plush yew
I'm using a data table to assign all of my items their values. It's very convenient since I used to have to go into each item BP to set values, but now I can do it from the data table. I'm wondering if I can make this even easier though? Because every individual item BP sets values based on the data table. But if I could set that up in the parent BP I wouldn't have to keep diving into individual BPs every time a new value gets added to the list. My only hangup is how I'd get the right reference to the data table row.
If I set a value in each individual BP on begin play such as row name then would that work back on the parent? Or would I need to set a small delay on the parent so that the child could update the variable before the parent sets everything based on the data table
grim ore
so the parent would hold the function but you would set a variable for the function from the child?
plush yew
Yeah, so right now the only difference between all my items is that drop down menu in row name. This one is for the backpack so I'm setting it based on the Backpack row
grim ore
I would think if you did the begin play, then called the super parent at that point the object is already constructed so the variable should be set. I really don;t know for sure tho as that is a really good question.
plush yew
I can test it out right now I suppose, I'll post the results
grim ore
well assuming the parent has the function call in the begin play, in this case it looks like you are doing it in the child anyways
unless you parent has another parent lol
regardless tho if the function is in the parent you can still call it from the child
so you would just on the begin play or construct call the function that is in the parent class as the child
sonic pagoda
Hey Mathew, have you ever had any success saving a Map(dictionary)
like having a map, editing its value, and saving it
plush yew
Oh I hadn't thought about it like that
That takes all the confusion away, I'll hook that up and see if it works. I don't see why it wouldn't. Thanks again @grim ore!
grim ore
I don't think I have had any problems with maps
sonic pagoda
i cant for the life of me get a map with a string key and structs to update its values
plush yew
It works that was such a simple solution wow this will save me so much time
grim ore
how are you doing the updating?
sonic pagoda
so i disconnected set members, because i created a separate bool array to fix my issue
in the meanwhile
that one pesky boolean
save game to slot, i check the save folder, 1 save file, i load that file, that bool is always false
(before the bool array fix*)
grim ore
where is the struct you are putting into that to change?
sonic pagoda
grim ore
ok for that setup there is no execute wire hooked up
sonic pagoda
yes that is correct, sorry i had disconnected because it wont work for me
grim ore
ok for a map you generally need to add the updated value to it for it to change
grim ore
the Add node adds or replaces a map value
grim ore
its' weird for sure but it makes sorta sense as it is supposed to be a unique key system
sonic pagoda
yeah, its different than arrays, i had watched your tutorial on it, but it had been a while I thought I had it all in my brain but apparently not
grim ore
don't feel bad I had to just wire it all up to double check lol. No set/get nodes for auto complete is a pain in the ass for maps
wintry forge
is there a way to equally space 3 objects from each other in the blueprint editor?
sonic pagoda
but the cool thing is you can use the key in a struct and it shows up beautifully (this is a procedural upgrade system im working on where you can generate widgets based on the amount of maps)
thanks again Mathew

can someone help me? after 4 days I still cant open up my project
I dont wanna lose all the progress

@wintry forge right click the nodes and look at the alignment options. I know you can vertically
summer turret
I opened my solution and pressed ctrl+f5 it says success in the bottom but then I try to open my project it still says the same thing
grim ore
How much of it was c++
wintry forge
I meant in the viewport Mathew, to clear that up. I cant seem to rightclick in the viewport for that functionality
summer turret
I opened the c++ editor just to take a look at it and tried to implement something but it was too complicated so I alt+f4 the c++ editor
and since then i cant open it
hidden aurora
any ideas how can i fade in/out the dialogue widget when an event is fired?
summer turret
I should have just stick with BPs
grim juniper
Random simple question, what version of UE4 did they add reroute nodes to the material editor?
wintry forge
when i hear node, i think of the programming part so im not sure if thats what you meant
hidden aurora
I tried that timeline but doesnt works
sonic pagoda
mathew, did i do it right, btw God bless you man you are so in demand today 😃
grim ore
@wintry forge ah yeah for that you can make a utility widget. Nothing built in.
sonic pagoda
i did a print string right after, and the bool is still false
hidden aurora
Isnt that add node just adding a blank input with used to true
summer turret
So theres no fix for my situation? it just doesnt feel right to lose all the stuff just coz i didnt press compile on my C++ editor
hidden aurora
set members alredy saves the value you have changed
sonic pagoda
but this is a map
hidden aurora
And?
sonic pagoda
if i highlight the node it says that add will overwrite
the value if it exists
well i used set members and print string came out false
doing this also came out false
i use a separate bool array, just to make sure im not doing something wrong
and it comes out true
hidden aurora
Is the string input on the find actually exists?
hidden aurora
but i think the add isnt necesary, cause its adding another entry with just that bool set to true
sonic pagoda
in any case, neither implementation works...
hidden aurora
Thats strange
sonic pagoda
retrosen regarding your dialogue issue
hidden aurora
try pluging a branch from the find bool and if false print string
maybe isnt finding an entry
sonic pagoda
you can make a fade in fade out animation timeline
and just fire that in the widget itself
hidden aurora
Doesnt works idk why
sonic pagoda
yeah good idea
another thing would be to just grab
off your dialogue reference right there in your picture
and get all the elements
so i imagine there is a text block, a box , etc. etc.
get a ref to all of them
and plug them into that set color node
sonic pagoda
right but if you click on its class
UI_NPCDialogue
it will take you to a widget
wont it
in any case those are the 2 solutions i know, in the widget blueprint make that animation timeline, or drag off that component and get the individual elements you want to fade
grim ore
ok so the issue you are having right now reinaldo is you are putting in a copy of the return from the map into the reference input on the set which will never work because programming 😦 you are going to need to basically get the info out , change it, and then change it in your map itself
sonic pagoda
its a lot easier in ASCII than it is in blueprints Mathew
lmao
aka a lot easier typed than done(for me)
hidden aurora
fixed it im silly
sonic pagoda
right here it says they are both references
okay but you said on the set members, yeah nevermind
but there is no "find" by reference
for maps
only find by copy
hidden aurora
I was executing the fade and after setting its visibility to true, thats why
reinaldo
maybe it doesnt works cause its in a function idk

Hello everyone, since we updated to 4.22 source, there is a crazy amount of log file produced when building.
it looks like this
Note: including file .... blabla.cpp
Note: including file ..... blabla.cpp
Anyone knows a way to disable that?
It produces a 16mb log file and its almost impossible to find errors
sonic pagoda
im just gonna give up and use my bool array, which never fails lol
@grim ore , in this case i have the reference
grim ore
@sonic pagoda holy hell I have no idea what is going on and it seems to only affect the bool wtf. every way I tried it would never save the boolean but a string next to the bool saves fine in a struct or a map or a map in a struct or whatever
wintry forge
is there a shortcut to manipulate(scale in this case) an object without manipulating its children?
grim ore
it is the weirdest thing, all the methods work we just got stuck on the fact that the bool did not and it threw us off
and yep the bool by itself in the save game is fine, its the bool in the struct in the map that is bogus
even the bool in the struct in the map in the struct is fine...
sonic pagoda
thats really weird
my biggest issue is i cant really google around, because everyone calls levels maps
and so when you look up anything related
its all related to levels
grim ore
It's beeeeyond weird because no other var type seems to have that issue
lol the engine calls it maps and levels depending on where you look at it.... it's an annoying thing
seriously different parts call the same object different things lol
sonic pagoda
yeah i just seen that
pulsar sorrel
unreal do not have per-instance material parameter, right?
or wrong? if wrong, how can i do that
grim ore
its not only that, its "MAPS" & Modes in the settings, it's Level when you make a new one, the default templates call them ThirdPersonMap
and Levels in the levels window, build navigation for level...
I give up on the bool, I would report it as a bug it has to be. All other variable types are fine in a map stuct when saving out but bools always keep the default value
i even tried multiple bools and it's still fubar
grim ore
it's like the save game serializer just skips them for some reason lol. If you reeaaaaally needed it you can always fake it with an integer lol
sonic pagoda
i just used a separate bool array
grim ore
even when you debug and pull back the data from the save game object it still shows it as changed, it's just when it loads that it either skips the changed data or it never saved it in the first place even tho the save game thingy shows them as changed which makes me think it's skipping the loading of the bool now that I think of it since it loads the default
sonic pagoda
oh i see what you say about the int though, just use a 0 or 1
grim ore
yep yep
sonic pagoda
yeah, simpler, ill try that then
grim ore
damned the dinner I want to figure out this issue lol
grim ore
only 5 and 3 can feed themselves 😛
sonic pagoda
thats some good programming 😁
grim ore
blah engine isnt up to date for source, will have to figure it out tomorrow at work lol. I have the part of the code that has the problem tho just have to step thru it while it loads and figure out if it's in the creation of the save game class or stuffing the file stream into that save game
sonic pagoda
the string in the upper left, the name of the key, the int changed from 0 to 1, and the bool set to true, but not
yeah its definitely funky
alright Mathew thanks a millionth time again
grim ore
well hopefully you can make something work, you were not crazy atleast lol
sonic pagoda
i consider it a win
yeah i got it to work, just sad that i thought i had maps figured out, but then happy now again that the int solution does the trick so yay
orchid rapids
Does anyone know the reason why I am unable to build unless I delete the game Intermediate folder every time? Its really killing my productivity 😦 its only happeneing on 1 machine

@pulsar sorrel it sounds like you are talking about dynamic material instances and yes it should be per instance if you want
sonic pagoda
in your material you can right click on a vector like a color for example and set it vector parameter, and then name it color
pulsar sorrel
is "dynamic material instances" exist? Thank you! I will googling about this keyword
sonic pagoda
right click on the material in the content browser
create a material instance, and it will have that parameter for you to mess with, but yes google will teach you lots more
pulsar sorrel
Okay, thanks you guys!
sonic pagoda
@grim ore there is some engine fuckery going on... its working now... i am able to set the bool to true, but only after placing that new int .. its like the bool or the struct got intimidated (its probably a struct issue though imo...)
grim ore
Hah
Maybe but I added an int and another bool and no go but I never tested the first one again...
sonic pagoda
and its saving as well and loading correctly... so go figure

How many of you guys use unreal in your day job?
heavy ether
well, i just started doing so today
i have it installed and have imported a few meshes from our existing project, and that's it. first time i've used it for more than a few minutes in several years
wintry forge
you guys think itll be possible to use this like an actual tripod
took me like 6 hours to make
heavy ether
... question for anyone: my existing Unity project has a bunch of ".mat" files that define the materials for things. It seems that Unity understands those files, but Unreal has no knowledge at all of them, and the only reference i can find to ".mat" files with a Google search is Matlab, which they clearly are not Matlab output.
Anyone know what outputs these, or what I can input them into to make them compatible with Unreal ?
@wintry forge keeping in mind that my knowledge level is quite out of date, i'd say it'd be pretty easy to use it like a tripod, if it's a skeletal
heavy ether
that's.. interesting. i thought unity was storing the material data in the meta files or something. so i wonder where the hell unity got the textures for these materials, since they aren't in the project as far as i can tell
manic pawn
they should be in the project as png/jpg/tga/whatever
meta files have something to do with tracking changes I think, there is no content in them
heavy ether
they might be off in some other directory, i guess, i'll have to dig through the project more, with both unity and unreal open at the same time
manic pawn
you'll want to create a new master material in unreal with the same parameters your shader in unity has, then make material instances off it and assign textures for each unity material you have
heavy ether
the assets that we've got are absolutely stupid for game engine use, things with like 40 individual pieces, thousands of verts, dozens of material slots . . .
but we're not building a game, so that's not so bad really
i... don't really understand what you just said there zeblote. 😄 i'm just at the "can we import our things to unreal" phase right now
tomorrow i'm going to try to get our entire test scene imported, so i can put down some code that uses it, and play with it from there.
wintry forge
@heavy ether its not skeletal
its made exclusively in the blueprints 😦
i hope i didnt waste my time hnng
heavy ether
in that case, i am definitely not qualified to answer that 😄
real pasture
RIP Spring sale.. until next year
fathom bridge
Yeah you will need to recreate those in unreal's material's editor
Squall are the legs each an individual mesh component?
If so you can move them independently
Maybe use a timeline
Esp if their origins are at the top pf the leg... Juat adjust the rotation with a timeline
heavy ether
i don't think we have any sort of master material in the Unity setup, i'll have to ping the people that were responsible for importing things there and see what they know
manic pawn
an unreal material is more similar to a unity shader than a unity material
heavy ether
this was not something that i did anything at all with, i just wrote code. i had to reference a shader once in all of it. 😄 i'll talk to the people responsible for that tomorrow and see what they can tell me and come back with more questions probably. thanks everyone 😃 see you tomorrow
my experience with materials goes back to unreal 2 pretty much, so i'm about technically useless there

Hello, i got an issue with my main menu, it launch well but i when i hit "new game" it won't disappear, the game is running in the background in the game and then the menu keep popping
tired oracle
try remove from parent before opening the level
muted willow
Thanks you for your help, the issue is still the same
tired oracle
try removing it in the palyercontroller or wherever you call it, thats how i handle umg
but i also thought umg automatically goes away when loading levels
muted willow
i'm really sorry i'm a total noob what do you mean by removing it from the playercontroller
this is the bp of the level it suppose to activate, maybe the issue is here

Is there a way to make a background follow the player character? Got a square background for my platformer but it zooms in so much that a window looks massive (city Skyline for half of it, a road for the rest)
wintry forge
can anyone give me some input? i made a tripod purely inside the blueprint viewport editor and I wanted to know if I could get it functioning properly. Would it be better to try and make a skeletal mesh instead?
muted willow
ok i think i got what you said @tired oracle , not the script is not in my player controller bp
Ok i figured out ! thanks ! i was building the script in level1 instead of titlemenu lol
wintry forge
is it possible to import a model i created in the blueprint viewport with cylinders/cubes into blender? i wanna add a skeletal mesh, think itd be easier to do that than program the tripod without one
regal mulch
Well, UE4 is not a modeling tool.
Creating stuff in the Blueprint Viewport is if it all placeholder worthy.
You should go into blender and create it there from scratch, properly.

i am having problems with 4.22 on my machine

Well, sounds like it's time to update your GPU drivers
proven oxide
on the latest
that was the first thing i tried
if it just failed all the time i would probably say it was the card being too old
cloud cobalt
Well it does look like that, or a driver problem
I'd uninstall the driver completely first and check again
Alternatively you can try running with Vulkan or OpenGL instead
If it also crashes with Vulkan, time to get a new GPU
proven oxide
no idea how to change that, I mean it is a Gen 3 laptop

cloud cobalt
Yeah in that case it means changing the laptop
proven oxide
but it doesnt fail all the time
cloud cobalt
Good news I guess
proven oxide
its only whilst i am away camping
cloud cobalt
Might be a power issue
regal mulch
You do have the power cable on it at all times, right?
Cause laptops without Power Cable usually go into a less energy hungry mode.
Which will cause the GPU to easily die if you need it to perform.

howdy folks. qVestion.
what kind of programming logic can reset a delay?
ok, more specific....
I'm stopping Tick after .... say.. 10 seconds
but restarting it if I get near the character after say... 2 sec
and then stopping it again, whcih starts a new 10 seconds delay
so the delays start overlapping
and I end up with the FIRST delay being unwanted
still moth
selection boxes?
still moth
so you can select multiple things at once?
copper flicker
oh, a timer, not a delay.. thx!
still moth
you really cant find a youtube tutorial for that? it seems like a common mechanic for RTS
vapid narwhal
I wonder, in terms of performance: If I have a simple object that has moving parts, like a treasure chest, where you can open the lid: is it better to have 2 static meshes animated via timeline or have it as one skeletal mesh with an animation?
sullen wraith
burnt nothing is showing up in my youtube search, ill keep looking, ive found some rts tutorials but its more about auto ai
not selecting them
still moth
do you even need an "animation" per se?.. couldnt you simply off-set the lid so that the hinge of the lid is right on the X axis or something and just use a script to rotate the mesh around the X axis when activated?
but in terms of which is better, two meshes or a skeletal, i doubt it really matters much
still moth
alright
vapid narwhal
well if I were to go with static meshes (1-4 for furniture like treasure chest, drawers, etc,.. simple stuff) id have them nested and manipulate rotation/translation values. But then I'd have 2 draw calls for each static mesh. Now I don't know if there is a number after which it makes sense to use a skeletal mesh instead, to reduce draw calls (like how much performance all the attached information use up compared to a static mesh) 😄
still moth
well, how do people normally handle doors? usually just rotating a static mesh i believe
abstract relic
sullen wraith
dammit, cant find anything about selection box :\
vapid narwhal
It seems like a more elegant way to use a skeletal mesh and animations, but I am worried about having a room full of skeletal meshes (for furniture with moving parts) being not performant compared to blueprints with timelines 😄 besides other issues that might arise along that way, that I haven't really considered yet (like baking light etc.)
still moth
elegant? if they both work in the same manner, get the same job done, go with whats easier
vapid narwhal
thanks @still moth 😃
still moth
in a timeline , you should be able to adjust how much it moves and when, so if you want an opening that starts off slow, then speeds up for a smooth start/stop, thats doable
so, not just having a lid or drawer move at 100% full velocity from first to last frame
vapid narwhal
yes, good old animation principles. 😄 Will make it a little tricky and I can't start at 0.0f, so I can actually reverse it properly with a bounce.
still moth
hmm, why does every youtube tutorial i see have event ticks in them?.. like.. thats not good advice for most of it
vapid narwhal
lack of knowledge about timers? 😮

Anyone who knows of any potential fix to the engine not wanting to start.. at all ?
- Windows updated yesterday, which seems as if today it simply just won't open any project at all, can't even create a new project, on any engine version
- The Splash Loading screen shows, and then after reaching 70-100% it just shuts down/crashes with no crash logs, and potentially opens the epic launcher again :/
vapid narwhal
Dang I remember there was an issue with the windows window manager / theme, but that's for quite old UE engine versions.

wispy raven
it doesn't detect when i'm moving left and right
dreamy lake
I really dont know then 😦
- Guess I might have to try and reinstall windows if I can't get this to work... ugh
vapid narwhal
maybe because GetMoveForward will override IsMoving=false in that order all the time? @wispy raven

wait
so, in order to fix it
what should i do?

Yeah idk.. my windows tends to be EXTREMELY slow at startups.. the majority of the time anyway.. like - you type in the password for your account, and then there's a very long wait time for windows to create the desktop, from which it then loads the rest of everything :S
oh nice thanks man

though, always back up important stuff
just because my experience with it has been rather okay (for a win10 product), doesnt say it will do so for others

I'm getting this warning when I'm spawning an actor (that has to adjust spawn location due to collision)
Any idea how to stop this warning pop up? There's no teleport flag on a spawn actor?
dim arch
teleport is used with moveactorto function
gleaming lotus
Thats not a function that I'm using though
Otherwise I'd be able to just tick that box and this warning wouldnt appear
dim arch
so the collision handling will adjust its location if the original spawn point is blocked
it doesnt teleport it when it does that
I dunno if there is an enum state which will do that, or if you need to override it in cpp

Yeah thats what I assumed 😛

Hey. Does anyone know why my float variable wont change its value? I have a blueprint that sets the value but the value doesnt change
grim ore
there are a few reasons why, what does your blueprint look like that is changing it? and what does your blueprint look like that is looking for the change
spark sonnet
its a linetrace, when blocking hit its supposed to change. And it goes to the set variable, just doesnt do anything when its activated
grim ore
so when you set a breakpoint on the set node with the new value you confirm when debugging that the value before the set is the old value and after settings it's not the new one?
spark sonnet
yes
grim ore
weird. There is not much else we can suggest then if it's just not setting the variable for some reason. You can post screenshots so we can see this code and maybe we can see something.
spark sonnet
ok
ill send screenshot
you see it is supposed to change to 0,5 now but its still at 0
grim ore
where do you check the current value?
grim ore
is it possible it is setting it to 0.5 and then the next frame changing it back to 0.0 ?
spark sonnet
grim ore
we can't really see your actual flow of the code
grim ore
when does it display the string? and also this is not debugging as you are not checking the variable after you set it. At the worst put a print string after you set the variable and print it out and see what it shows.
spark sonnet
ok I put a string after it and now it says 0,5 but its not steering at 0,5,
So the variable is working, it just wont set the steering input

spent past couple hours trying to make a click drag selection box
i cant figure it out
or find any tutorials anywhere
heavy ether
keeping in mind that my experience is quite out of date, and there might be far better ways to do it now, what i'd do if i were using unreal 3 😃 is get the screen coordinates of your box, project those points into world space, then do a box trace from those points into the world for whatever distance is necessary to pick things up.
sullen wraith
what im doing atm pretty much :\
heavy ether
so what's not working
also, it is so nice to be able to talk in terms that i actually know again, discussing things on unity forums was like working in a foreign language.
sullen wraith
when i left click it randomly spawns all massive
and as yo ucan see my cursor is in the middle
it's not following my mouse at all
heavy ether
maybe should draw a 2d-box so you can see that your screen coordinates are right first
i'm sort of thinking that there might be some maths involved if you're not on a straight top-down view though

Who is "the number 1" tutorial guy on youtube? And is using a version of UE4 such as 4.12 going to really hinder my progress versus learning current version. Also can a project from 4.12 be "upgraded" to a more current state?

blueprint or c++?
Unless you have a really good reason to using 4.12, not recommended at all. And yes, upgrading from 4.12 to any new version is super easy

Compared to c++ its limited in many areas
Like multiplayer for example
If you know how to c++, I'd recommend a mix between both
shrewd quarry
Say my role as a developer would have nothing to do with multiplayer functionality, more just level design, character mechanics and enemy mechanics. Would blueprints still be recommended and maybe even preferred (taking into consideration time restraints)
@fast finch
and also thank you for your time
shrewd quarry
Currently just two people but as soon as we realize we need more I'm sure we'll look
Most of that stuff will be handled by me unless we luck out and find someone
fast finch
Blueprint is great for prototyping or handling non heavy things
Its especially a great tool for designers and non-programmers like yourself
So, if you don't know how to code, definitely just do stuff in blueprint, and a programmer can move some stuff to c++ later if needed
shrewd quarry
Basically, just do that but be aware of my limitations so either learn C++ or get someone?
Thanks again
fast finch
Depends on how big and complex your game is, If its not super complex, it can all be done in blueprint, granted c++ gives better performance but it wont matter if the project isnt very complex
shrewd quarry
@fast finch last question, doing an official tutorial on unreal's youtube channel from 3 years ago isn't recommended? If not who's current and has basic fundamentals to get you going?

Or does Paper2D use a totally different type of controller / character setup?
I've just noticed there are more tutorials doing the sorts of things I want on paper2D, don't want to get started, invest time, and then realize that there are things I can't do with the standard 2.5D sidescroller template, that could be done in the Paper2D setup

I guess what im asking is how can I reference an actor variable inside a widget
crisp hawk
is it possible to have a game mode per streamed level?
like, one main game mode for your persistent level, then a separate like sub game mode for each streamed level?
or would you need to put the game mode logic inside the stream level?
deep basin
is it nor possible in unreal to add a widget component in c++, like I can add a static mesh or sphere or w/e? createdefaultsubobject doesn't work for some reason....

@idle bolt which projects? anything that is public is normally on the Learn tab on the Launcher or in the resources forum (probably nothing here)

@grim ore Thanks. I'm looking for sample AR project files. In the comments of this tutorial Joe Graf says that they are planning to release a sample project with 4.21 that shows the setup for an ARSkylight. https://medium.com/@joe.j.graf/ar-environment-probes-in-ue4-4-20-afda05bcc587
grim ore
@lime gull you should be able to reference a variable in a widget like any other way of referencing. If this is multiplayer then you would likely keep the variable somewhere else and have the individual widgets pull that data since widgets are client side only.
I remember seeing that one
lime gull
What do i use as the objext when casting?
grim ore
I dont know how your project is set up, I cant answer that
idle bolt
Joe Graf: "The plan is to release a sample with 4.21". I was wondering where that sample would be available for download. I guess in the Learn tab, but I'm not seeing any AR sample projects at all in the Learn tab.
grim ore
yeah I am trying to remember where I downloaded it from, it's not on the asset sharing that I can see
idle bolt
@wraith bridge Were you able to get the ARSkylight working correctly to reflect an enviroment?
grim ore
I don't think I tested that, I think I just tested the plane setup stuff
idle bolt
Gotcha
grim ore
I know I tested it tho I remember the menu in the bottom right. I was comparing AR to Unity at the time
lime gull
I know is hard to see but im trying to get the variable from the actor to bind with thw widget but it keeps asking for a target
idle bolt
Thanks for the tip about the Learn tab @grim ore I hadn't actually noticed that!
grim ore
it is hard to see, use print screen on your keyboard and paste it into Paint to crop out what you want then you can paste it in here or imgur.com

Hello guys, can someone that already used the Ability System in Unreal send me a pm please ? I have a few question
lime gull
ComputerBP Is my actor, and this is all a get percent function in my widget
grim ore
your widget is going to have to know about that computer BP some how. Is there more than one?
lime gull
Right now there's only on, but the plan was to add more
grim ore
yep then you are going to have to keep a list of all of those somewhere for all your widgets to access. Game Mode or Game State or Game Instance is a universal spot that is easy to get at if these are points of interest. Getting them into there is going to be harder unless they tell the GameXXX item or your GameXXX item gets all of them and knows which is which
lime gull
How do I save them to a game mode?
grim ore
you can make variables for them in the game mode and have them when they spawn or whatever get the game mode and tell the game mode about themselves.
so like Get Game Mode -> Cast to your game mode -> Set MyComputerVariable and have it set to self (this is calling it from your computer)
lime gull
What should the variable type be
grim ore
which variable
lime gull
The one in the game mode for the computer
grim ore
I would assume it would be ComputerBP since that is what you want to keep track of ?
lime gull
Maybe im misinterpreting something
So in the game mode I set variables for the computers?
grim ore
yes, you can crate a variable or variables or an array in your game mode that can keep track of your computers
then when the computer is created, being play for example or whatever, it can tell the game mode about itself and set that variable in your game mode
then anything else in the game when running can get that variable from the game mode and do whatever
@idle bolt man I tried over and over and I just cannot find where I got it from. I know I was on a kick learning AR for UE4 and Unity but I cannot seem to find where I got that file from.
grave spruce
grim ore
neato
lime gull
How would I save the computer as a variable? Would I get the progress from the computer and assign that number to its own variable on the game mode?
grim ore
you would from the computer Get Game Mode -> Cast to your game mode -> Set the variable you created and for the input pin you would put the self variable
this is assigning the item that is doing this (self) to the variable on your game mode so the game mode has a reference to that item. then at anytime you can do your Get Game mode -> Cast to your game mode -> Get your variable for the computer -> do whatever you wanted to do with that computer
like get your percentage for example
heck you could if you didnt want to keep asking the game mode you could at some point have your widget ask the game mode once, and then save a local reference to that item inside of it so it can just talk to it directly from then on.
grim ore
buuut.... lots of these ways are just making extra work and duplicating reference so you have to find a way that works for your project
lime gull
All I need now is to increase the variable when the player holds an input and it works!

@grim ore Thank you man

Hey guys, I am trying to access this variable in MyCharacter.h from my animationBP but it doesn't show up when I look for the get function for it
Whenever I extend off of TryGetPawnOwner it doesn't show up in the list
paper kernel
because it returns a generic actor
kindred viper
get the character and cast to it, then access the roll var

Have anyone tested new Nvidia drivers already?
kindred viper
I wouldn't say tested. I installed them so they are testing me
next badger
@kindred viper does RT works in ue4?
kindred viper
I am not sure yet. Im gonna make a cup of tea and fire it up. I need a project to test though as Im no artist or lighting guy
brazen forum
@paper kernel what do you mean it returns a generic actor? I dont quite understand the concept because I can extend off of trygetpawnowner and easily access the components it has, and then acces that component's variable. So why cant I just access my roll variable?
kindred viper
because roll i sin the character class and you are getting the pawn. Although similar, the slight difference is in the inheritence
gleaming narwhal
@next badger I haven't seen any reports of it not working since we released 4.22. Sjoerd's learning theater talk from GDC contains a lot of information: https://youtu.be/EekCn4wed1E
kindred viper
if it did return the character as a pawn owner, then you would need to still at least cast as character to access it
next badger
@gleaming narwhal i'm talking about new nvidia drivers, for 10series
brazen forum
alright. Thx
gleaming narwhal
Ah! That one I'm still unsure on. But I did see a comparison on what you could expect in terms of performance. 1080 seems to be the only card where you'll get acceptable performance.

@gleaming narwhal we are interested in dxr lightmass
also would be cool to render out videos from ue4 frame by frame
kindred viper
I wish I had some talent for the lighting to run up a new project or something as a test. It really makes me feel like im pigeonholed into coding 😄
next badger
@kindred viper there was a great tutorial on setting up the lighting in the games (cinematic like)
i'll try to find it
iirc this one https://www.youtube.com/watch?v=MaUt1p3PQvo
kindred viper
yeah I remember skimming that once and putting it in my watch later list.
thanks. ill check it out when I finish this peice
next badger
unfortunately ue4 lighting slightly changed since then...like there are capsule lights available now and some other features, but general knowledge in this video is still valid
kindred viper
ahh ill keep it in mind. Also though, im useless at this stuff. I used to have fun with it in the early days of ue4 but it kind of got lost on me as I got into plugins and engine stuff
next badger
@kindred viper hah, well, i'm not telling you to change your focus, it's just in case you want some info on lighting
kindred viper
oh I like to know a bit about everything if I can. RTX has sparked my need to know, so its all good 😄

I need some help. I use Oculus Medium to create models in VR. When I export them and put them into unreal, it appears like polygons are missing. Seeing "Degenerate Polygons", even if I export the model with even less polygons, it still happens.
Example
fierce tulip
either their normals are flipped, or oculus medium just does a shitty job.
cyan ridge
I dunno, I've seen many people import their stuff into Unreal and working well. My friend tried flipping the normals and tried to unify them but got a weird result.

Does anyone know if this volumetric modelling stuff works in 4.22? It looks like this in the preview map
summer turret
Failed to import 'C:/Users/Me/Creative Cloud Files/Audio/fdfasdf.wav'. Failed to create asset '/Game/Audio/fdfasdf'.
Please see Output Log for details.
where do i find output log?
dark depot
wrong encoding i imagine then
abstract relic
You gotta make it 16 bits I believe
mighty copper
hey Casarome if you look at the model from inside can you see the missing polygons? if you can they are flipped. if not they are missing.
abstract relic
It’s been a long time but it’s definitely encoding issue
dark depot
just open it in audacity and export .wav 16bit
summer turret
i wish unreal would accept mp3s
dark depot
why you want your sound to be crap?
kindred viper
lol 😄
abstract relic
The player can’t judge if you make them go deaf first 😜
summer turret
i changed it to 16 bit and still saying same thing 😦
dark depot
https://docs.unrealengine.com/en-US/Engine/Audio/WAV make sure its also PCM or another listed here
cyan ridge
@mighty copper I'll try that out, can you flip normals in Unreal?
summer turret
yeah just fixed it I used 8 bit instead of 16
kindred viper
@cyan ridge in 4.22 there are some new tools for mesh editing that let you select faces and flip the normals
fierce tulip
<_< I just said the normals might be flipped

Poor @fierce tulip being ignored 😜

guys you know the VectorLength node in blueprint?
How do I use that function in c++?
grim ore
welp the api docs say its part of the kismet math library
brazen forum
Ive been trying to do that. I even included it
grim ore
yep so if we look at the header for that we find /** Returns the length of the vector */ UFUNCTION(BlueprintPure, meta=(DisplayName = "VectorLength", ScriptMethod = "Length", Keywords="magnitude"), Category="Math|Vector") static float VSize(FVector A);
so UKismetMathLibrary::VSize(your vector here) should return back a float of the length
and to back that up if we look at the API docs at http://api.unrealengine.com/INT/API/Runtime/Engine/Kismet/UKismetMathLibrary/index.html we find entries for VSize and other methods that return the length of a vector

thx dude!!

So I have a level developed with a Nav Mesh bounds volume in it so I can supposedly move in VR...I can open up the VR preview and look around in VR, but the controllers and whatnot don't seem to be recognized, as I don't have hands. Is there something else I need to get VR working in my level?

The reason my Wallrun isn’t working is it seems that there Overlap event isn’t triggering, anyone want to help me fix this?

You take the vector and use Size()
FVector MyVec(1.f, 1.f, 1.f);
Float Size = MyVec.Size();
That's another way. It's a function in FVector

i think it asks you if you wanna convert your project files over, you ight wanna keep the engine youre using now, download the new one, then try it out though @tawdry narwhal

How does one delete a c++ class?
grim ore
close VS, delete the files from your folder in your file explorer, delete your build/intermediate/saved folders, delete your .sln file, right click the .uproject and generate your solution file, rebuild your project, hope it all worked
technically you can just delete the C++ files but then UE4 won't know about it so that is what the rest is for lol

My little warning that says "lighting needs to be rebuilt" disappeared a few hours ago, and it's hard to remember when it's ready to go vs not...is there a way to get that back?

when the lighting is built or when you need to build it?
when it needs to be built it should tell you, if you are building it you should have swarm running in the taskbar
