also getting warnings saying that my gamemode failed to compile, but its fine in the editor?

#

no errors when packaging either. just when i launch the server

dense wharf May 26, 2018, 5:15 AM

#

its like my structure blueprint got corrupt or something. I'm guessing this is a bug?

dense wharf May 26, 2018, 5:51 AM

#

so duplicating the struct and reconnecting the new one fixed all errors, but still this bug scares me. I'm lucky I didnt use the struct hundreds of times or that would have been a nightmare reconnecting everything

stable hemlock May 26, 2018, 6:58 AM

#

@dense wharf hey! glad to see you are making progress. if you have declared a struct in unreal, there is a bug where if you add or remove an element there may be issues with the struct later if you reference it. so basically you would need to add all elements you need to add at the beginning - this happened for me in my 6dof game, and i eventually fixed it by deleting and re-creating struct with all connections re-done, although i recently helped someone on here that said he solved it by trying to recompile a few times.

dense wharf May 26, 2018, 8:07 AM

#

@stable hemlock yo! Yeah I duplicated it, gave it a new name, and reconnected and it fixed it. Sounds like a serious bug, no?

stable hemlock May 26, 2018, 8:08 AM

#

yea

dense wharf May 26, 2018, 8:09 AM

but other than that i set up my own ded server on an EC2 instance and its working great

#

6 cents an hour 😛

stable hemlock May 26, 2018, 8:10 AM

#

wow great

#

so

#

how did you do the ded server

#

you built a dedicated target in vs?

dense wharf May 26, 2018, 8:13 AM

#

yeah just following that guide

#

getting the EC2 server to work took awhile tho

#

its a ghetto solution for hosting a server lol

stable hemlock May 26, 2018, 8:28 AM

#

that wiki you said you hate? 😛

#

you actually used amazon. crazy

#

can you like share some of your steps when you get a chance?

#

i could benefit from the knowledge actually 😃

#

here's some basics from what i have so far. if you get a chance could you let me know how you ddi the EC2 thing? like general details would be great i can really use it.

📎 unknown.png

#

i want to transition to ded server, i am happy to pay 6 cents an hour for it. that's crazy and amazing and i wana get into it and i need to for my steam 6dof game 😃

#

wow thats about $40 a month. that's so cool man. congrats on getting your ded server up on amazon L:)

dense wharf May 26, 2018, 8:40 AM

Yeah it took me awhile man lol

i'd suggest read thru this first just to get an idea

Revised and much faster, run your own high-end cloud gaming servic...

Playing Witcher 3, a GPU-intensive game on a 2015 fanless Macbook

#

but ignore what he does basically

#

the only thing that I followed was the steps at the very bottom called Using the pre-made AMI

#

and then since we're just testing our games, use the t2.medium server instance

#

its 6 cents an hour and it runs my game perfectly fine with me and my friend testing it

#

but yeah it still can be complicated at first lol it took me several hours to figure it out, but ive never ran a remote server before

#

also make sure you add an EBS drive to your instance because that's where you'll store your project. Don't put your project on the desktop or whatever

#

then you can turn your instance on and off whenever you want and not worry about losing your files

#

but yeah PM me if you get stuck so we don't fill this chat up haha

aaaaa these accidental rebuilds are getting annoying

#

is there anything we can do to prevent rebuilding the engine?

lost linden May 27, 2018, 6:57 PM

#

I dont know but mine has been doing it too. I never touch my Engine source either. The worst thing is, other projects that relied on that build, also have to rebuild everything.

elder falcon May 27, 2018, 7:01 PM

#

made quick batch files to make the Developer, Editor, Runtime source folders read-only

#

no more accidental header changes

#

can't set programs read only or it fails to generate project files

lost linden May 27, 2018, 7:15 PM

#

im not sure how I ever had any changes. like I said I literally never touch the engine source. im a pure plugin guy

elder falcon May 27, 2018, 7:21 PM

#

🤷

#

I often accidentally save engine headers since I have a habit of randomly pressing ctrl s

lost linden May 27, 2018, 7:22 PM

yeah me too lol

elder falcon May 27, 2018, 7:22 PM

#

so this prevents that from wasting 15 minutes

lost linden May 27, 2018, 7:22 PM

#

but I dont do it with engine source. Its happened more frequently recently too

elder falcon May 27, 2018, 7:22 PM

#

I'm sure it's not the only way to trigger a useless rebuild

#

just the most common one for me

#

it would be nice if ubt could detect like

#

"this header says it changed but it actually didn't so let's not rebuild"

lost linden May 27, 2018, 7:24 PM

#

it would be nice if it didn't even try unless you told it to 😄

elder falcon May 27, 2018, 7:26 PM

#

lost linden May 27, 2018, 7:28 PM

#

no idea. I have never touched any UBT UHT stuff. Its just part of the Epic Magic I leave alone

spiral mortar May 27, 2018, 7:37 PM

#

Why are you building from source @elder falcon ?

elder falcon May 27, 2018, 7:42 PM

#

so I can fix or change stuff that doesn't work the way I need it to

#

but actually having to change something is rare

#

so it's nice to not have the constant danger of an engine rebuild if I wasn't actively changing stuff

spiral mortar May 27, 2018, 7:43 PM

#

And why not using a binary build?

elder falcon May 27, 2018, 7:43 PM

#

then I can't change things

spiral mortar May 27, 2018, 7:43 PM

#

hehe

#

So you change things pretty often?

Interesting

lost linden May 27, 2018, 7:54 PM

I want to add another pin (that uses the gbuffer) to the materials Result node.
By default there are 2 custom pins (x and y). The custom shader model I'm using added a new one (z).

Anyone know what the max number of custom pins that can be added is?
From what I can tell, it looks like you can add a max of 2 v3s to the gbuffer.

hollow kernel May 28, 2018, 1:58 AM

Actually, I can repurpose one of the existing custom pins, but it'd still be nice to know how many custom pins can be added.

I will take the opportunity to ask a final big question.
For a while now I have the problem that when I use the hot-reload function and press play the editor crashes.
I am not able to find the cause of this

#

I don't know if this sounds familiar to anyone and thus having a direct idea what the problem is?

astral sapphire May 30, 2018, 1:36 PM

#

@still ember i believe hotreload crash bug popping from time to time, and since you're using pretty old build it still maybe unresolved there

wicked whale May 30, 2018, 2:32 PM

#

Hi all, how do I go about setting up the Crash Reporter to pop up whenever a source built version of the engine crashes? I've built it in the .sln but it's not active.

astral sapphire May 30, 2018, 2:34 PM

#

@wicked whale CrashReportClient works with Shipping configuration afaik

wicked whale May 30, 2018, 2:35 PM

#

@astral sapphire Thanks, I'll give it a try

Hello. What would be the entry point to start understanding the rendering process in UE4? Is it Renderer/Private/SceneRendering.cpp?

#

I'm trying to understand the Engine architecture so I'm able to implement custom changes to it, mostly related to shadowing and masking.

#

ok, never mind, I found this: https://docs.unrealengine.com/en-US/Programming/Rendering/Overview

wicked whale May 30, 2018, 4:19 PM

#

@astral sapphire Hi, I went ahead and rebuilt the engine for Shipping but Crash Report client still doesn't pop up after crashes and the engine is no longer generating new crash logs.

#

Am I dumb 🤔

#

yes I'm dumb

#

I finally understood someone else's advice and renamed the crash reporter executable to just be "CrashReportClient.exe". It's working now

astral sapphire May 30, 2018, 4:22 PM

#

@wicked whale oh...that one, haha, true

#

@wicked whale pls tell if the debug version also working with the crash reporter (if you eventually switch back to one)

wicked whale May 30, 2018, 4:24 PM

#

Yeah I'll rebuild debug editor and see if this trick also works

#

Sometime later today though since I'm on a laptop and it takes a good while to do that build lol

astral sapphire May 30, 2018, 4:25 PM

#

yeah...i wish octobuild still worked for newer ue4 versions

#

XGEControlWorker should work for parallel builds but it's not using build caches as i can see

wicked whale May 30, 2018, 4:33 PM

#

Isn't incredibuild a thing?

elder falcon May 30, 2018, 4:38 PM

#

incredibuild is managed by that xge thing

but the only thing unreal seems to do with it is distributed builds across multiple machines, if you don't have that it's useless

@elder falcon octobuild that used xge was really useful, it used build caches that incredibuild produced, so 2nd build was 5 min instead of 40

I got a project that works like a clock using launcher version of UE4 (Android build). However, I needed to start using Oculus fork and I build engine from the source. Now my project crashes on the device: https://pastebin.com/mFn4xnXL

Pastebin

#

Same 4.19.2 source (except with updates SDKs from Oculus), but something seems to be broken

#

Any idea how to work around this issue ?

astral sapphire May 31, 2018, 6:16 PM

#

@cosmic stump why oculus fork?

lost linden May 31, 2018, 6:48 PM

#

because KFC forks snap easily

#

well they are more like sporks but you get me

elder falcon May 31, 2018, 6:56 PM

#

so I've been wondering... compiling development editor project seems to result in about 500 less jobs then compiling ue4 development editor, and appears to work fine for starting the editor

#

what is all that extra stuff being built as part of the ue4 target?

#

(and why is it being built if it's not necessary?)

cosmic stump May 31, 2018, 7:23 PM

#

@astral sapphire because Oculus has all SDKs current.

astral sapphire May 31, 2018, 7:25 PM

#

@cosmic stump why you need current sdk?

cosmic stump May 31, 2018, 7:30 PM

#

huh!? Why not to stick with UE 4.11 or something like that?

#

silly question

#

obviously you don't need to keep up with Oculus SDKs if you don't develop for Oculus hardware.

astral sapphire May 31, 2018, 7:35 PM

#

@cosmic stump no, i mean, what version of oculus sdk 4.19.2 have?

#

and what version fork has

cosmic stump May 31, 2018, 7:36 PM

#

1.21 I think and fork has 1.26

astral sapphire May 31, 2018, 7:36 PM

#

and you need that difference right?

cosmic stump May 31, 2018, 7:36 PM

#

🤦

#

hmm... just got e-mail from Oculus saying something about "async loaded thread enabled" option. Gotta see if I have it off or on. Might be a workaround.

are you trolling me today?

astral sapphire May 31, 2018, 7:42 PM

@cosmic stump that's OVRP version, != SDK version

cosmic stump May 31, 2018, 7:43 PM

#

OVRP, Platform, Audio, Avatars are referred to as Oculus SDKs

#

SDK with "s" after SDK

#

meaning multiple components

#

regardless, 4.19.2 from Epic has outdated OVRP and Platform SDK\

#

4.19.2 from Oculus has everything current (except it has no Avatars)

#

how is this related to my issues with project crashing on the device ?

cosmic stump Jun 1, 2018, 12:45 AM

#

so, using "Async Loading Thread Enabled" was the issue

#

with that option disabled everything runs fine (except loading time is long now)

proven grove Jun 1, 2018, 12:50 AM

how the hell does a TArray actually work

#

its such a mess of abstraction its impossible to tell what goes where

#

or how any of it works below top level

cosmic stump Jun 1, 2018, 1:20 AM

#

now, the weird thing is that Oculus fork cpp files are "binary identical" to Epic's repo cpp files (related to async thread loading and streaming)

#

that makes me wonder if launcher version of UE4 is different than source version, even though it's the same version number

elder falcon Jun 1, 2018, 1:30 AM

#

@proven grove tarray works pretty straight forward tho

proven grove Jun 1, 2018, 1:30 AM

#

pretty straight forwards

#

what

#

it has 10 layers of abstraction in it

#

at least

#

i had to hop between 5 diffrent files just to find a class that didnt inherit

elder falcon Jun 1, 2018, 1:30 AM

#

it only has the element type and the allocator as abstractions really

#

what part of it are you wondering about

proven grove Jun 1, 2018, 1:31 AM

#

all of it

#

i'm looking to make my own array for another project

#

and im looking through the unreal source code to see how they do it

#

but they just made it so damn complex

elder falcon Jun 1, 2018, 1:31 AM

#

you could just use std::vector

proven grove Jun 1, 2018, 1:32 AM

#

~~but using std is a sign of weakness~~

elder falcon Jun 1, 2018, 1:32 AM

#

it's not necessarily possible to make it less complex if you want it to be as performant and versatile

proven grove Jun 1, 2018, 1:32 AM

#

i do try not to use std whenever possible

#

i just want to have more control over it

#

and i dont care as much about performance as it should never really be an issue

elder falcon Jun 1, 2018, 1:33 AM

#

some of the complexity comes from it being able to use move semantics on elements supporting it

proven grove Jun 1, 2018, 1:33 AM

#

so are there any particular parts i should look at?

elder falcon Jun 1, 2018, 1:33 AM

#

I mean.. all of it is necessary to make the thing work

proven grove Jun 1, 2018, 1:33 AM

#

but where should i start?

#

of all the 3000 lines, which one should i start at

elder falcon Jun 1, 2018, 1:34 AM

#

probably with the constructor to see what the starting point is, and then follow the add method to see what happens when you insert a thing

proven grove Jun 1, 2018, 1:35 AM

#

ill see where it leads me

#

thanks for the help

elder falcon Jun 1, 2018, 1:35 AM

Now that I can pass a material function back into c++

#

I have a compute shader that I would like to inject this into

#

so instead of injecting it into a material

#

I just want to inject this into my c++ shader

elder falcon Jun 1, 2018, 1:48 AM

#

are you sure that's a thing you can do

cold wigeon Jun 1, 2018, 1:48 AM

#

of course

#

has it been done before? No

elder falcon Jun 1, 2018, 1:48 AM

#

doesn't the material function only contain nodes and need a real material graph to be able to compile it

cold wigeon Jun 1, 2018, 1:51 AM

#

If I have to spawn up a material, and then get the hlsl code, and then inject this into the c++ shader thats okay to

#

I would just create a bare material \

elder falcon Jun 1, 2018, 1:52 AM

#

welll good luck with that 😅

cold wigeon Jun 1, 2018, 1:53 AM

#

hey, if you can't help, then just stop bloating the chat

pearl fulcrum Jun 1, 2018, 1:53 AM

#

Uh yeah you need a graph to compile

cold wigeon Jun 1, 2018, 1:53 AM

#

thats fine

#

this isn't runtime stuff

pearl fulcrum Jun 1, 2018, 1:53 AM

#

I don't have any examples for you though - you're outside of my wheelhouse here

cold wigeon Jun 1, 2018, 1:53 AM

#

yea Im well aware that this is some unreal stuff here

#

the issue is, we can create our shader in a material, but we can't use it unless we assign it as a material

pearl fulcrum Jun 1, 2018, 1:54 AM

#

If you're really feeling brave you might be able to emulate the graph

cold wigeon Jun 1, 2018, 1:55 AM

#

we just need to have manual control over when material functions are run, and we need to access the output

#

we don't want to actually see the results, its a gpu data manipulator

#

think cuda

#

we can use the graph in the editor

#

maybe I can just use a material and just hijack the output

#

and maybe I can hijack the fps tick

pearl fulcrum Jun 1, 2018, 1:59 AM

#

What I'm curious about is why you're using ue4 mat at all if you want a compute shader

cold wigeon Jun 1, 2018, 2:00 AM

#

I already have a compute shader

#

we are working on a game changing plugin

#

and I need to be able to let the user to create the shader in the editor like a sane person, and it gets injected into our c++ shader because its data only

#

we can't use the typical material because the only way to run the shader is to assign the material

#

but then we can't control the tick
we can't get the data results

#

and also the results would produce visual garbage

#

also, we don't want to waste resources creating an actor and then hiding the actor

#

no to mention damn resource management skipping the material if its not in view ect

#

also our compute shader allows cpu and gpu access to the data

elder falcon Jun 1, 2018, 2:13 AM

#

you can draw materials to render targets which can then be read on the gpu without spawning actors/other nonsense

cold wigeon Jun 1, 2018, 2:18 AM

#

okay, as long as I can use the render target as my input to the material

elder falcon Jun 1, 2018, 2:19 AM

#

they can read from render targets if you set up a texture parameter and assign it, and write to one by drawing the material to it

cold wigeon Jun 1, 2018, 2:22 AM

#

okay thank you
so if I wanted to store weather simulation data, RTF R32f should be a big enough container for accuracy right?

#

i wonder what would happen if i made FORCEINLINE expand to nothing instead of expanding to always inline

elder falcon Jun 1, 2018, 2:23 AM

#

you'd have to rebuild the engine

#

otherwise I would not expect much to change

proven grove Jun 1, 2018, 2:25 AM

#

it would make it a whole lot easier to debug

#

im just worried about performance

#

would the diffrence be noticable enough to warrent the better debugging potential?

#

or would the performance hit be unnoticable

elder falcon Jun 1, 2018, 2:27 AM

#

noone really knows, the auto optimization is pretty much magic

#

it's possible some parts will run like garbage while others don't change at all

#

you don't really see any other cpp projects put so much forceinline on everything

#

it's even possible some parts might run better with forceinline removed

proven grove Jun 1, 2018, 2:30 AM

actually I think I know what the problem might be

they have all the definitions for forceinline methods in the headers, below the class declarations

proven grove Jun 1, 2018, 2:48 AM

#

i changed them all

elder falcon Jun 1, 2018, 2:48 AM

#

making them not inline now results in a duplicate definition in each cpp

proven grove Jun 1, 2018, 2:48 AM

#

oh god

#

so should i just have it expand to inline

#

instead of forceinline

elder falcon Jun 1, 2018, 2:49 AM

#

that'd work

proven grove Jun 1, 2018, 2:49 AM

#

ill try that then

#

ok, trying again

#

no linking errors so far

elder falcon Jun 1, 2018, 2:59 AM

I wonder what would happen if you set every method to forceinline

proven grove Jun 1, 2018, 3:01 AM

100mb dYSM files probably

game going from 400mb to 1 bg

elder falcon Jun 1, 2018, 3:02 AM

#

the packaged exe is already ridiculous big tbh

#

and if you make a linux build it becomes 600mb like what

proven grove Jun 1, 2018, 3:05 AM

#

on mac the editor app file is about 650mb

#

but the dynamic libararies are about 15mb each

#

and theres a couple thousand

elder falcon Jun 1, 2018, 3:06 AM

#

ye but I'm talking about a shipping build of the game only

#

it ends up with the largest executables I've ever seen in any game engine

proven grove Jun 1, 2018, 3:07 AM

#

the fps template is about 430mb packaged on mac

#

the c++ variant is anyway

#

idk about blueprints

proven grove Jun 1, 2018, 11:36 AM

#

well, it compiled

#

so when it has all the forced inlining stuff, its about 44gb total on a fresh build

#

its still 44gb

#

but all the binaries have gone from being 17-20mb each

#

down to just 3mb each

#

the editor executable went from 620mb to 590mb

#

so it is slightly smaller

#

time too see the performance

#

shader compiling is significantly faster

#

like about 4 times as fast

#

it usually take my computer 20 minues to compile about 2500 shaders

#

it just did it in 2

#

holy moly

#

thats, an actual performance boost

#

thats

#

really damn good

#

and thats a really noticable thing as well

#

like, most artsits spend alot of time compiling shaders

#

so a performance boost like that is great

#

thats an important thing

#

uht also ran about 5 seconds faster on my project

#

went from 24 seconds to 19

#

why did this one change affect so much

elder falcon Jun 1, 2018, 11:47 AM

ofc the real question is whether in an actual real-world project, it now runs at higher fps

you just replaced it with "inline" right?

proven grove Jun 1, 2018, 11:53 AM

yeah

elder falcon Jun 1, 2018, 11:53 AM

so that basically makes it do nothing

proven grove Jun 1, 2018, 11:53 AM

#

wont compile if it expands to nothing

elder falcon Jun 1, 2018, 11:54 AM

#

since the compiler just ignores normal inline

proven grove Jun 1, 2018, 11:54 AM

#

it needs to expand to inline for some reason

#

not always

#

it will most of the time

#

but sometimes it wont

elder falcon Jun 1, 2018, 11:54 AM

it needs to be inline because of the definitions in the headers

proven grove Jun 1, 2018, 11:54 AM

does anyone know exactly how the server updates the client's location when it gets out of sync?

proven grove Jun 1, 2018, 12:54 PM

#

it beats them into submission

#

i think

clear nacelle Jun 1, 2018, 12:55 PM

#

for example, launching a character with 200 ping will cause the client to teleport to where they should be once they receive the RPC

#

but the thing i cant figure out is how it manages to put it back to a position where the client is in charge of their movement

#

so once the client updates the position, its actually ahead of where the server sees it

#

https://gyazo.com/37778b841f58d937adc8d6c6c3a962d4

Gyazo

▶ Play video

#

left is the server's view, right is a 200 ping client

#

client still manages to land first

elder falcon Jun 1, 2018, 12:58 PM

#

that's a pretty complex system

#

the client stores moves it sent previously so it can replay them on top of an update from the server in case of a de-sync

clear nacelle Jun 1, 2018, 12:59 PM

#

makes sense

#

the reason i ask is because id rather have it setup to quickly interpolate through what the server saw

#

instead of that jarring teleport

elder falcon Jun 1, 2018, 1:00 PM

#

have the thing launching the character run on the client too

#

the server will still be authorative

clear nacelle Jun 1, 2018, 1:01 PM

#

that works fine when the client launches itself but not when someone else shoots that character

#

then the guy who shot is stuck waiting on the RTT between both clients to the server before he sees the other guy get knocked back

elder falcon Jun 1, 2018, 1:03 PM

#

hmm, I don't know in that case

#

maybe people in #multiplayer will have ideas

clear nacelle Jun 1, 2018, 1:04 PM

#

asked there a while ago, nobody had any answers

#

my goal with this is just to disable movement replication on the character and do it manually so i can correct it with my own code, but finding out how to put the client ahead of the server again, and in the correct location, is the hard part

west haven Jun 1, 2018, 1:05 PM

#

isnt 200ms a bit too much to expect smooth gameplay for this sort of stuff anyway? its almost half a second roundtrip time... and if you want to disable the client prediction system you can always implement your own character movement component

clear nacelle Jun 1, 2018, 1:05 PM

#

im surprised UE4 still just teleports to correct it

#

yeah 200ms is just to really demonstrate the issue, but it can still be slightly noticeable at 50

quake live handles it well when a player receives a knockback, im basically trying to copy that

I'm dense, how to I add a file to a source build and actually have it included by UBT?

Nevermind, I realized that adding existing file in VS wouldn't actually move it out of the intermediate folder despite displaying it in a different place in the solution... that doesn't make any sense to me! But manually moving the file in explorer solved it.

gray glade Jun 1, 2018, 6:04 PM

Basically you're facing corrupted memory

Either deleted or not created

Hi, if anyone could help me with this error I would be greatly appreciative. I'm trying to build the engine from source in visual studio for a dedicated server build of game but when I try and load the editor from source I keep getting this error and upon clicking ok the process ends and I can't do anything with my project

#

I'm not aware of any plugin called Audio Capture that is being used in my project

#

These are the errors preventing the build of the AudioCapture module as far as I can tell.

You might try just straight up removing the plugin

how can i speed up the build of my project

#

it is quicker when i use the launcher version not the source version

#

i mean at least 3 times faster

spiral mortar Jun 11, 2018, 1:41 PM

#

Why are you using a source version @limber jacinth ?

limber jacinth Jun 11, 2018, 1:44 PM

#

for dedicated server?

spiral mortar Jun 11, 2018, 1:52 PM

You need that?

#

Ah yes

limber jacinth Jun 11, 2018, 2:06 PM

#

yeah

#

just weird why it takes ages on the source build not the binary build from launcher

maybe my ue4 build target was wrong?

why would you delete vr from the engine?

but you don't need to delete it from the engine sourc

You should delete strings too

Hey there! I'm currently trying to create a binary build from my source build(which works fine, I can run and compile projects etc. No issues here).

The command I'm using is this: AutomationTool.exe BuildGraph -target="Make Installed Build Win64" -script=Engine/Build/InstalledEngineBuild.xml -set:WithDDC=false -set:SignExecutables=false -set:EmbedSrcSrvInfo=true -set:HostPlatformOnly=true

At 4/9, Compile UE4Game Win64 however I get an error and I sadly have no idea what it exactly means. Can someone help me out?

https://pastebin.com/E49FEnzz

(Shows whole log for 4/9, but error is at the bottom)

Thanks in advance for any tips <3

and, what form of pull requests do you think epic would accept

#

i've done a ton of low level optimisation in certain parts of the engine

and i've reduced build times by about 2 minutes

and i've reduced the amount and complexity of the code in certain parts as well

its nothing that anyone using the api would ever see

otherwise, it will get ignored for 3 years

terse lake Jun 13, 2018, 11:14 AM

#

@elder falcon I've done that, but the only solutions I find regarding that say that I should put something into my project build.cs

#

The thing is, this is an engine build and I dont have a project-related build.cs. And putting that into the UE4game build. cs just results in an error that says it doesn't exist. (Two possible solutions: Definitions.Add("BOOST_SYSTEM_NOEXCEPT"); and UEBuildConfiguration.bForceEnableExceptions = true;)

#

Is there something I'm missing? Can I put these options for an engine build, too?

#

It's really weird, the normal compiled build works just fine. Only this rocket build throws this error.

     * The system calls this method to notify the widget that a mouse button was pressed within it. This event is bubbled.
     *
     * @param MyGeometry The Geometry of the widget receiving the event
     * @param MouseEvent Information about the input event
     * @return Whether the event was handled along with possible requests for the system to take action.
     */
    virtual FReply OnMouseButtonDown(const FGeometry& MyGeometry, const FPointerEvent& MouseEvent);```
what does it mean "this event is bubbled" or "this event is tunneled"?

#

my current problem is that a UMG Image's "OnMouseButtonDown" event isn't called every time an image is clicked quickly & repeatedly, but only every second time

#

so i'm trying to find where the problem is in source

lost linden Jun 13, 2018, 4:18 PM

#

@stable hemlock bubbling is a term used for when a reaction to an event is passed through a system of checks. When it hits the right one, the search ends (figuratively popping the bubble). In the case of Unreal, input events are bubbled through a chain and where you want to capture it is where you use an FReply(handled); or unhandled if it you want it to pass to the next in the chain

stable hemlock Jun 13, 2018, 4:19 PM

#

I see. this has nothing to do with the bug then...

lost linden Jun 13, 2018, 4:20 PM

#

probably not. I would output the current focus on each click so you can see if it changes at any time.

regal yoke Jun 13, 2018, 6:11 PM

#

Anyone know where keyboard shortcuts are defined? I want to add a shortcut that’s not in the key binding editor

wicked whale Jun 13, 2018, 7:34 PM

#

@lost linden @stable hemlock The term "bubbling" is also probably referential to the way events are passed through widget hierarchy, e.g. an event that starts at the bottom of a chain of widgets will "bubble" up the chain until a widget handles it. This is why events that proceed in the opposite direction are said to "tunnel", which can be achieved by using a function like OnPreviewMouseButtonDown. No clue what the "preview" part of the nomenclature is supposed to represent.

#

But in any case if UMG event isn't being handled in an expected manner then it's worth inspecting with Widget Reflector, I believe you can view info on what's receiving input through there.

regal yoke Jun 13, 2018, 8:23 PM

#

I should specify that I only need to know where keyboard commands/bindings are in the code. From there, I should be able to figure it out

elder falcon Jun 13, 2018, 8:26 PM

#

it's kind of spread out? lots of things involved with key bindings

#

I guess if you want to figure out how the mapping works you could start exploring at UInputSettings::ActionMappings

#

from there it'll be copied to UPlayerInput and stuff

gloomy hamlet Jun 13, 2018, 9:13 PM

#

@stable hemlock Don't have access to source just now, but I'd guess highly likely that the other half of the clicks are triggering a double click event instead.

#

You may be able to disable that somewhere, or otherwise just handle it too and call the same code from both.

stable hemlock Jun 13, 2018, 10:23 PM

#

it's true, it's because it's treated as double click. don't know how to disable it though, and an image can only catch OnMouseDown, not doubleclick

So, I just pulled the latest 4.20 branch, compiled it and am in the process of launching the engine, and the splash screen says 4.21 👀 https://gyazo.com/9b601eaaafc70d342e41d1313f479a02

I also think the process hung, it's been sitting at 45% worryingly long

alright nevermind it launched fine. Kinda curious what causes that version number to be one higher than it should be, maybe someone accidentally the version number string?

Naw, I hadn't pulled from master, there's a branch explicitly named 4.20. I'm guessing it's some weird result of already having the repo open in another instance of git bash that had hung

Nice idea. I've worked around it for now with a small hack in my code, but if it doesn't suffice I'll look into that.
