the bloody handle is still an utter mystery

#

@regal mulch oh, I misread what I need to update the location of... I thought you meant my attach point (which is just parented for me)... you meant the physics handle's location? but that doesn't have one... it's not a scene component it tells me

#

urrr... wait... its starting to fall in place now... but wow... why is it so different to a physics constraint?

regal mulch Feb 25, 2019, 9:20 PM

#

Well Physics Constrains is something else

#

PhysicsConstrains is something you can use to make a physics door

#

But you would grab and pull the door open via the Handle

#

The Handle is actually really simple. Wonder where the problem comes from.

#

You grab something at LocationX.

#

And then you set the TargetLocation to move it.

Not that this ever results in an actual project but well.

glacial pecan Feb 25, 2019, 9:46 PM

#

@regal mulch ok, so now I replaced the physics constraint with the physics handle... super illogical, but works... although I haven't figured out how to actually get it to line up with the bloody location and rotation I'm feeding it

#

I mean, sure, it attaches at that point, but it keeps the grabbed objects relative transform at grab time

#

which I guess perhaps you'd normally want (but I don't... I had a nice snapping thing going on... which wasn't physics driven, unfortunately)

regal mulch Feb 25, 2019, 9:49 PM

Alright let me shed some light on it.

@plush yew You can use something that is around all the time in your level like GameMode. It hangs out in the level and you can get it from pretty much anywhere and have it control the music.

plush yew Feb 25, 2019, 9:53 PM

#

Ahh.

#

Now my question is...

#

Is this literally all it takes for a Sound Cue to play random background music in a loop?

#

📎 unknown.png

#

i.e pick a song at random, wait till it finishes, then pick another one

weary basalt Feb 25, 2019, 9:54 PM

#

Pretty much

plush yew Feb 25, 2019, 9:55 PM

#

Assuming the wave players should NOT be looping though? lol

regal mulch Feb 25, 2019, 9:56 PM

#

@glacial pecan The PhysicsHandle uses actual PhysicX under the hood.

When you call "GrabComponent" it takes a Location. Whatever you pass in becomes the TargetLocation and the TargetRotation will be constructed from the passed Component, which both you can later update.
As far as I understand, these are used to create a Physics Joint. They basically construct a RigidBody and all kinds of PhysicX stuff from that Component and put a joint on it.

When you call "SetTargetLocationAndRotation", you update the location and rotation of that joint.
This will effectively move the RigidBody (which is the component your grabbed), while making sure it has some sort of physics applied to it.

#

You can visualize this in the real world as having a small wooden block in front of you.
When you grab it, you put a nail into the location where you grab it and when you update the location you move the nail around.

#

Which will move the block. You can then imagine what happens if you just hold the nail at it's head (the wooden block will swing around)

glacial pecan Feb 25, 2019, 9:59 PM

#

so I basically need to calculate the rotation difference between where I want it to snap and where it is at the point of grab?

regal mulch Feb 25, 2019, 9:59 PM

#

Just that you could technically specify a location in UE4 that is not close to the block.
In the real world you kinda have to have physical contact with the object to stuck the nail in.

#

I'm pretty sure you can move the grabbed Actor into your hand

#

Rotate it as you wish

#

And then grab it

#

So if you image an imaginary point right in the middle of you hand palm

#

That could be a mesh in your game

#

And the point is a socket or a scene component

#

You can set the location and rotation of the actor you wish to grab to the one of that point

#

Effectively moving it into your hand

#

THEN you grab the actor by that point

#

Or rather the root component of that actor

plush yew Feb 25, 2019, 10:01 PM

#

@weary basalt What would I do in the sound cue to make the engine choose another song once the current one finishes?

regal mulch Feb 25, 2019, 10:01 PM

#

And when updating the target location and rotation you specific the same location and rotation of that imaginary point

#

Cause you want to make sure it moves with it

glacial pecan Feb 25, 2019, 10:02 PM

#

right, so in essence, keep the non-physical snap animation, and THEN activate the handle?

regal mulch Feb 25, 2019, 10:02 PM

#

Yes

#

https://images-na.ssl-images-amazon.com/images/I/71Tf9fpMvvL._SL1500_.jpg

#

You can put the hammer into the hand

#

And then grab it

glacial pecan Feb 25, 2019, 10:02 PM

#

@regal mulch can I go further, and not even activate the physics handle unless I detect a hit on that component?

#

because I notice it lags behind my motion controller

weary basalt Feb 25, 2019, 10:02 PM

#

@plush yew Typically i make a component on the PlayerController which is like a small music player. It will shuffle the songs and then play them one at a time until the last one and then reshuffles and starts again.

glacial pecan Feb 25, 2019, 10:02 PM

#

(and it didn't before with a straight up attach)

regal mulch Feb 25, 2019, 10:02 PM

#

The Lagging Behind is because of the late update iirc

glacial pecan Feb 25, 2019, 10:03 PM

#

ok... so wonder how flaky it is to enable and disable the handle on hit events... 😃

#

I'll try tomorrow!

weary basalt Feb 25, 2019, 10:03 PM

#

@plush yew Assuming its for background ambient music.

@regal mulch thank you for all your help and information! it was really great!

regal mulch Feb 25, 2019, 10:04 PM

The lagging behind should be fixable. Doubt it has something to do with the actual handle

#

You mean this sort of "lagging"?

#

(the beam)

glacial pecan Feb 25, 2019, 10:05 PM

#

@regal mulch either way, when I'm not hitting something, it's a bit unnecessary to calculate physics, correct?

plush yew Feb 25, 2019, 10:05 PM

#

@weary basalt Well the music that plays DOES depend on where in the UI the player is, and what the game's current state is. Like, I may want to use a different track list depending on what in-game country the player's in. I may also want to fade into some action tracks if the player is being hacked, in a government alert, is hacking, etc

regal mulch Feb 25, 2019, 10:05 PM

#

@glacial pecan Well the main idea of using the Physics handle is to simulate physics properly

#

If you have the hammer grabbed

#

And you hit the table

#

It will probably NOT go through the table

glacial pecan Feb 25, 2019, 10:05 PM

#

@regal mulch that sort of lagging I have at work, but not in my project at home 😄 the lag here is much smoother, so it feels as if it's a physics thing

weary basalt Feb 25, 2019, 10:06 PM

#

@plush yew I guess it just means your music component will have to be more complex. Having event driven sound mixing like what your after will take time to get right. You could get your menus to feed their track list to the component and it can fade in/out as it receives new track lists or something.

regal mulch Feb 25, 2019, 10:07 PM

#

You can fix that lag by turning of late update. Don't ask me where to turn it off, my VR Headsets are all uninstalled in the closet :P @glacial pecan

I am trying to position some tooltips, I could get the first in the right position by adding an offset but it does not generalise. I have created a general 'tooltip' widget with variables I can edit from outside, these variables are the text that fills the widget and a vector 2d structure for location. The text thing is working fine (I just input a string - to text) but I am not sure how to do the location thing, I am using this node because it looked promising but it doesn't seem to do anything.

regal mulch Feb 25, 2019, 10:11 PM

#

UMG should have a ToolTip for you already

#

Each Widget has a ToolTip parameter

#

Which you can bind to to create your own tooltip.

plush yew Feb 25, 2019, 10:12 PM

#

I know but its too small and I would like to personalise

regal mulch Feb 25, 2019, 10:12 PM

You technically don't need to position it

#

Just bind to it

#

That should let you create your own widget

plush yew Feb 25, 2019, 10:14 PM

do you mean the 'tooltiptext' bind or the 'tooltipwidget' bind?

regal mulch Feb 25, 2019, 10:14 PM

If you bind to that you can return a widget

plush yew Feb 25, 2019, 10:15 PM

Thats what I'm doing

#

The problem is I am not sure how to set the position

regal mulch Feb 25, 2019, 10:15 PM

It should set the location by itself o.o

plush yew Feb 25, 2019, 10:15 PM

But since its a custom widget its somewhere off in the distance I think

@plush yew the default TPP template has the character set up like that, it should be Nothing checked on Pawn (rotation X) for the 3 settings on the root. it should be all 4 checked under Camera Settings on the Camera Boom (spring arm), and it should be use pawn control rotation unchecked on the Camera itself under Camera Options. The Character Movemement under Rotation Settings should have "orient rotation to movement" checked.

plush yew Feb 26, 2019, 12:03 AM

#

It lets you play any Sound Wave, Sound Cue, etc, through a blueprint function library. When you tell it to play a track, it does a 2-second crossfade between the new track and what it's currently playing, then it destroys the old track to save precious RAM

#

the only issue is if you switch tracks too quickly, the game gets a little confused and doesn't fade out the previous track

#

I need to introduce some sort of buffer or delay of some sort so the game waits until a current crossfade is done before it tries another one

Whats the performance like?

plush yew Feb 26, 2019, 12:10 AM

#

my terminal? I haven't done any benchmarking but it seems to run at 60 FPS to my eyes

#

in the game's splash screen, it uses the same terminal rendering code to display some linux kernel spam as the game starts up, writing a line to the terminal every 10 ms and it doesn't seem to lag

#

It used to struggle a lot with large amounts of text in the display buffer but ever since I stopped rendering text that wouldn't be visible a few months ago, it's never had any issues

plush yew Feb 26, 2019, 12:14 AM

#

back when I was doing this game in MonoGame we actually gad a full blown master/slave pseudoterminal system set up like you'd find in real Linux but I would have no clue how to do that in C++

#

and the current terminal I wrote works well enough

#

The way I achieve multicolor is pretty neat too

#

the game will look for an & in the output buffer, then look at the next character after it. If the next character is a hex digit then it's a color code and it treats it the same way as the Windows COLOR command

#

if it sees a *, that means bold

#

_ means italic

#

- is both

#

and r is regular

#

if it sees a ! then the text blinks, haven't implemented that yet

worn granite Feb 26, 2019, 12:16 AM

#

Interesting.

plush yew Feb 26, 2019, 12:17 AM

#

and if it sees two &s in a row, it sees that as "literally render an &"

#

I also use latent actions for getting user input from the terminal

#

Which makes writing terminal commands in c++ a total pain in the male genital area but....

#

I'm not even sure how I would accomplish the same sort of api in C++ without going into multithreading hell

yeah... give me a sec

i need it so 1 anim plays in 3 meshes

#

I used to do it 1 mesh 1 track but its time consuming

reef mist Feb 26, 2019, 12:51 AM

is there a reason you can't just have each mesh have their own track in sequencer to play the anim?

yeah

I have 3 meshes

The 3 meshes have the same skeleton

I want that when i put 1 anim on the bp it affects all 3 meshes

not only 1'

reef mist Feb 26, 2019, 12:57 AM

when you say put an 'animation on the bp' do you mean use an 'Play Animation' node?

@grim ore Fresh TPP seems to have what I'm looking for when stationary but while moving I can turn my character by moving the mouse, I'm trying to add a keybind so that I can freely move the camera around the character while moving. If you're familiar with WoW I'm essentially trying to replicate what happens when you hold LMB while inputting movement. I've uploaded this video to show what I'm trying to achieve: https://www.youtube.com/watch?v=h25JwkrpYxs&feature=youtu.be

Also, all of the rolling done in the video is thanks to you! Those anim notifies are lifechanging and I can do so much more with my system now that I know how to use them, so thank you again!

How to stop camera from influencing player rotation?

In my game there are certain instances where I don't want the camera to be influencing the movement of the player. For example, if you're rolling and look be...

▶ Play video

#

I have a feeling that this situation is going to be more complex than just toggling some options in the menu, I think I might have to set the camera up to move completely independently from the player other than inheriting its location for starters

why is this an infinite loop?

wary wave Feb 26, 2019, 3:14 AM

#

delay inside a while loop 🤢

#

and obviously it's an infinite loop because 'Battle' is always true

silver crown Feb 26, 2019, 3:15 AM

#

Looping delay ftw

sullen wraith Feb 26, 2019, 3:15 AM

#

nah battleis changed on component end overlap :#

#

hmm

worn granite Feb 26, 2019, 3:15 AM

#

you'd be better off using a branch in place of that while loop, then just exploiting that you can "physically" loop the exec wire back.

sullen wraith Feb 26, 2019, 3:16 AM

#

so whats the best way to have a delay with a loop?

worn granite Feb 26, 2019, 3:16 AM

#

Also, modifying the variable outside the loop body doesn't count.

sullen wraith Feb 26, 2019, 3:16 AM

#

ill give that a go immutable 😃

wary wave Feb 26, 2019, 3:17 AM

#

Component End Overlap literally never happens

#

because you never, ever break out of that loop

worn granite Feb 26, 2019, 3:17 AM

#

You lose the chance to alter the variable before getting an infinite loop by entering the delay node, but even then, you don't modify the variable in the loop body.

sullen wraith Feb 26, 2019, 3:17 AM

#

that worked Immutable 😃

Really, you want to use a timer.

sullen wraith Feb 26, 2019, 3:18 AM

#

@wary wave it does fire

worn granite Feb 26, 2019, 3:18 AM

#

When the condition becomes true, you want to start a recurring action. When it is no longer true, you want to stop the recurring action.

#

This is the use case of a timer.

sullen wraith Feb 26, 2019, 3:18 AM

#

nah timer doesn't fit the need for it

worn granite Feb 26, 2019, 3:18 AM

#

There's a good reason the node isn't called "DoOnceEveryInterval"

sullen wraith Feb 26, 2019, 3:18 AM

#

the branch trick has worked 😃

#

essentially what this blueprint is for

#

is two ships

#

when they reach eachother they fight

#

and kill eachother

#

when one is killed, it destroys it

#

thus ending the overlap

#

its working now 😃

worn granite Feb 26, 2019, 3:19 AM

#

this is the recurring bit.

You're obviously doing this every 1s

Use the get spline length node and then divide the result by how many objects you wanna spawn

paper kernel Feb 26, 2019, 10:00 AM

#

ok so I forgot to add, the objects are at set offset

#

like 500 units to right

red kindle Feb 26, 2019, 10:01 AM

#

any answer for my qustion

frozen oak Feb 26, 2019, 10:02 AM

Ok, get spline length and divide the redult by your offset to see how many units you should spawn?

sullen wraith Feb 26, 2019, 10:02 AM

is there a way to make it so ai dont take the most direct path?

ie go in a single line?

#

I know I saw a trick ones where someone added a texture to a decal and was able to export it like that. But thats a while ago and I cant find it atm

paper kernel Feb 26, 2019, 10:06 AM

#

the equation has to take turn radius into account

#

because inner side has less distance by a factor of offset

frozen oak Feb 26, 2019, 10:08 AM

#

Huh, if you get spline length and divide that up evenly all distances should be the same

paper kernel Feb 26, 2019, 10:08 AM

#

it's not after you apply offset from the spline

#

like car differential

#

inner side always turns less

frozen oak Feb 26, 2019, 10:09 AM

#

So you want to offset the meshes off the spline ?

paper kernel Feb 26, 2019, 10:09 AM

#

yea

#

like runway lights, except runway isn't straight

frozen oak Feb 26, 2019, 10:10 AM

#

How are you doing the offset?

paper kernel Feb 26, 2019, 10:10 AM

#

multiplying right vector with float

frozen oak Feb 26, 2019, 10:12 AM

#

So the distance between the meshes gets bigger when you move it?

#

Screenshots would be really helpfull tbh

PREVIEW!

Preview 1 of the upcoming 4.22 release is available now on the Launcher and GitHub. We are making this Preview available so that our developer community

Auto instancing?

the link I linked had more information. basically the engine can go from "you want to draw 100 meshes that are the same, here is 100 meshes drawn one at a time" to "you want to draw 100 meshes that are the same or similar, here is 4 draw calls for all of them"

Good afternoon everyone! I’m running some tests on my project with a demo map. The map has ~700-1000 actors including enemies, trees, etc. with low-poly models. I’m running an above average PC build but am running into performance issues when enemies chase the player. This is a top-down Diablo style game so when there are say, 50 enemies chasing the player the FPS drops to about 25 from ~110 FPS with no enemies. I’m wondering if my issue can be alleviated with culling as I have none setup so every actor is constantly being populated for the PC (from my understanding of culling.) I’m debating what type of culling I should use for this style of game, I am leaning toward Camera Frustum. Thoughts on if Culling might be fix my performance issues, or any likely causes you can think of?

next badger Feb 26, 2019, 6:15 PM

#

You may run the performance logger an look on your time cycles

lethal breach Feb 26, 2019, 6:15 PM

#

Performance logger you say? Time to go look into that! Thanks for the tool recommendation.

grim ore Feb 26, 2019, 6:16 PM

#

@lethal breach you can guess at the issues or you can profile it and see the exact costs for everything in a frame. If you do the later you can find out the direct issue and then work towards fixing it, it might not be an issue that culling would improve.

lethal breach Feb 26, 2019, 6:17 PM

#

How do I go about profiling it?

next badger Feb 26, 2019, 6:17 PM

#

@lethal breach it's called "Session Frontend"

lethal breach Feb 26, 2019, 6:18 PM

#

I am fairly new to UE4, I have a basic understanding but am still learning regularly - I view your tutorials almost daily for example. The latest was your tutorial on Lerp Nodes, which I have to say - Thanks for your awesome tutorials!

#

Thanks, I’ll look into that!

grim ore Feb 26, 2019, 6:19 PM

#

😃 glad to hear they are helpful. There are a few different ways to profile so that page is a good start. Just getting a simple cpu profile is a good start to go "damn I didn't know my BP tick logic was taking up 200ms" type stuff lol

next badger Feb 26, 2019, 6:20 PM

#

I wish ue4 used Session Frontend profiler as default tool

#

it's way more useful than on screen logs

grim ore Feb 26, 2019, 6:20 PM

#

agree, it's just not a simple thing to make work out of the box compared to bam something pretty is on the screen with big red lines lol

lethal breach Feb 26, 2019, 6:21 PM

#

I’m hoping it isn’t my BP logic as my entire game is BP, I have no ticks running and the game is single player only. But hopefully the Session Frontend logger and the profiling will help point me in the direction.

grim ore Feb 26, 2019, 6:21 PM

#

well you have AI running and that might be using ticks

#

hey preview 3 of 4.22 is out, yay

lethal breach Feb 26, 2019, 6:22 PM

#

Ah, that’s true. And I’ve wondered if my Behavior trees are the issue. If as I mentioned I have 50 enemies, each running a behavior free... That could become costly.

grim ore Feb 26, 2019, 6:22 PM

#

yep that's why my first thought was profiling 😃

dim plover Feb 26, 2019, 6:23 PM

#

Also, I think, performance in PIE is significantly lower than standalone.

lethal breach Feb 26, 2019, 6:24 PM

#

That’s what I’ve been told. But the lag I’m experiencing is while running the game in a stand-alone game viewport.

next badger Feb 26, 2019, 6:24 PM

#

@dim plover PIE as new window or directly in the editor?

lethal breach Feb 26, 2019, 6:24 PM

#

Question, does a culled actor run it’s Behavior tree? Or does culling just affect the visual draw?

dim plover Feb 26, 2019, 6:26 PM

#

I think I meant PIE directly in editor, but I'm not sure PIE with standalone also suffers. Though, 25 FPS regardless would not translate well anyway.

olive schooner Feb 26, 2019, 6:26 PM

#

I finally set up our team git but when I cloned the repos on my computer and launched the editor, I can see it updated a bunch of files in Content/StarterContent... How and why this happened? 😖

plush yew Feb 26, 2019, 6:30 PM

#

@honest vale the mesh moves 👀 doesn't that make more draw calls

honest vale Feb 26, 2019, 6:31 PM

#

why would it

plush yew Feb 26, 2019, 6:31 PM

#

Because it's moving it......?

next badger Feb 26, 2019, 6:31 PM

#

@olive schooner what files exactly?

honest vale Feb 26, 2019, 6:31 PM

#

the engine does a draw call every single frame for every single mesh

plush yew Feb 26, 2019, 6:31 PM

#

The draws would be calculating it in a new location

honest vale Feb 26, 2019, 6:31 PM

#

it is done always per frame

plush yew Feb 26, 2019, 6:32 PM

#

Huhm

honest vale Feb 26, 2019, 6:32 PM

#

regardless of whether something moves or not

sudden agate Feb 26, 2019, 6:33 PM

#

A Drawcall is just a fetch from the GPU so it knows what needs to be drawn.
Instanced Meshes means the Data for a single mesh is already on the GPU and you just feed transform (which may already be on the GPU) data to it.

#

the Drawcall is therefore reduced because you dont have any mesh data sent to the GPU

plush yew Feb 26, 2019, 6:34 PM

#

So...

#

Okay...

#

But...

#

Why

sudden agate Feb 26, 2019, 6:34 PM

#

Moving meshes do not change anything, because the Transform is just updated

#

not the mesh itself

#

super dooper simplified

plush yew Feb 26, 2019, 6:34 PM

#

How does it separate the draw vs transform

#

Isn't that extra calculations

sudden agate Feb 26, 2019, 6:35 PM

#

Rendering a Mesh is just a mathetmatical concatenation of matrices

grim ore Feb 26, 2019, 6:36 PM

#

I have 100 meshes. I send 100 meshes to the GPU. the GPU draws 100 meshes. regardless of the position that frame or whatever it's going to draw 100 meshes. with instancing it pushes 1 mesh that matches your others to the GPU, then tells it where that 1 mesh should be drawn. the GPU can handle this super fast rather than having to take in all that info from the computer.

plush yew Feb 26, 2019, 6:36 PM

#

Then aren't meshes already instanced

grim ore Feb 26, 2019, 6:37 PM

#

meshes are instanced only if you make them instanced basically. Only if you do the work ahead of time to make it so. yes there is more calculations but compared to pushing out all that data to the GPU it's minor

#

everything has a cost. instancing meshes can have a lower cost than just drawing them all individually 😃

plush yew Feb 26, 2019, 6:38 PM

#

That doesn't sound right to me

#

It's the same amount of draws ?

grim ore Feb 26, 2019, 6:38 PM

#

nope

honest vale Feb 26, 2019, 6:38 PM

#

each draw call requires some CPU work

#

that CPU work for a thousand (simple) meshes is greater than the time it takes to just render all of them in a combined mesh

plush yew Feb 26, 2019, 6:39 PM

#

I get the concept

#

But it sounds like bs imo

honest vale Feb 26, 2019, 6:39 PM

#

it's not a matter of your opinion dude 😄

grim ore Feb 26, 2019, 6:40 PM

#

say you had a picture in real life. every stroke of paint or ink is a draw call. when you are done you have the finished product which is 1 draw call then if you ever wanted to reproduce it. figuring out all the stuff for making that picture ahead of time and just doing it all at once can be cheaper than drawing a line,then getting another line to draw, drawing that line, etc.

plush yew Feb 26, 2019, 6:40 PM

#

But that's what loading a game does...?

grim ore Feb 26, 2019, 6:40 PM

#

loading a game != drawing a frame

plush yew Feb 26, 2019, 6:40 PM

#

Or starting a map

#

Everything is already there

grim ore Feb 26, 2019, 6:40 PM

#

you don't, and cannot, have the entire game in memory

plush yew Feb 26, 2019, 6:41 PM

Instancing is probably good for a scene with 120mil polys

grim ore Feb 26, 2019, 6:55 PM

Instancing is "free" performance so it's good for anything that could use it.

plush yew Feb 26, 2019, 6:55 PM

To elaborate, I still don't get how saying it uses less calls actively makes it use less calls. You have your same meshes, because it knows all calls of one mesh, it knows all calls of the others? But in order for the game to know That, it has to be loaded, to see and interact with it the GPU needs to call it anyway?

#

As well that's just saying that x mesh draws = y mesh calls, and labels all meshes as x. But all the same meshes are already x, so wouldn't the GPU already know all meshes are x?

sudden agate Feb 26, 2019, 7:27 PM

#

@plush yew eh. no.
The GPU doesnt know anything.

#

you are sending Mesh Data per frame

plush yew Feb 26, 2019, 7:27 PM

#

It's like it's saying draw mesh x in different locations, but it still has to know all the meshes.

#

🤷

@next badger

What do you mean by verify the location of the git root with some proper tool ?
My .gitignore only filters out builtdata .uassets
My .gitattributes correctly tracks .uassets with

Content/** filter=lfs diff=lfs merge=lfs -text

I restored the branch to it's original state, opened the Editor and it added the same files so I think it "updates" my Content folder with the EngineContent from my editor installation, which somehow is different... I'm so lost 😄 I'm gonna just commit my "new" files and hope it forgets about everything... Otherwise I'll .gitignore StarterContent and move everything I want to another folder. My environment artist doesn't understand that stuff and she pokes around starter content changing stuff...

livid haven Feb 26, 2019, 7:40 PM

#

You mean to say you created a C++ class using the wizard in the UE4 editor? That tries to hot reload.

#

Don't do that.

Hot reload is at best of limited use if you know exactly how it works and thus know what it can or can't do without issues.

(Someone asking about Source vs Public is definitely not ready for that)

I know what I said, and that was in response to MathewW commenting about hot reload being usable. It may be to him, but it probably will be more of a hassle for you without that depth of knowledge.

#

Public and Private folders exist to separate files that should be accessible to other modules.

marsh garnet Feb 26, 2019, 7:45 PM

#

So where do I put my class?

livid haven Feb 26, 2019, 7:45 PM

It's a convention, not a strict rule.

I wouldn't just shove stuff under Source. I'd follow the convention.

marsh garnet Feb 26, 2019, 7:45 PM

#

Ok?

livid haven Feb 26, 2019, 7:45 PM

#

Private should contain files that only the module should access.

#

Public should contain files that other modules also need access to.

grim ore Feb 26, 2019, 7:46 PM

#

put all your files in the root directory if you are lost on where to put it, worst that can happen is you can't find it later lol

livid haven Feb 26, 2019, 7:46 PM

#

Generally, *.cpp should be in private, because there's practically never a reason you need to access a CPP file from another module.

marsh garnet Feb 26, 2019, 7:47 PM

#

Ok

#

And how do I turn off hot reload again? Thanks btw

livid haven Feb 26, 2019, 7:47 PM

#

Now, not all header files should be in Public, but what is in Public is typically, exclusively header files. *.h

grim ore Feb 26, 2019, 7:47 PM

#

just don't hit the Compile button in the editor (hot reload), or build the project with the editor open (hot reload)

upper heart Feb 26, 2019, 7:48 PM

#

I think you should start with a single module mindset if you aren't working on a plugin type project.

livid haven Feb 26, 2019, 7:48 PM

#

You can start by putting everything in Private until you know for a fact you need to include one of those headers inside of another module. Then, you move it to Public.

No. This is not something you "fix".

#

Topkek So you're saying this is how Fortnite was made?

grim ore Feb 26, 2019, 7:55 PM

#

eventually if you work with UE4 and C++ enough you can learn when you should have the editor open and when it should be closed when working in C++

livid haven Feb 26, 2019, 7:55 PM

#

Yes. I am. As someone who has been on the Fortnite dev team for 5 years.

Hot reload has several issues, but the biggest ones aren't a matter of bugs with hot reload, they're fundamental limitations of what it means to swap code in a running program.

dim plover Feb 26, 2019, 7:55 PM

#

I wish Hot Reload was completely taken out, though. As an option or something. Sometimes I accidentally build with the editor open.

livid haven Feb 26, 2019, 7:56 PM

Live++ is pretty awesome and somewhat better.

Hot reload is somewhere between trying to replace a car engine, while it's running and doing that trick where you pull a tablecloth without moving all the tableware on it - except you then proceed to try to put another tablecloth in there at the same time.

grim ore Feb 26, 2019, 7:58 PM

grim ore Feb 26, 2019, 7:58 PM

#

I literally could not remember it

livid haven Feb 26, 2019, 7:58 PM

#

But, I've been appreciating Live++.

#

The difference with Live++ is that it doesn't need to try to swap DLLs like hot reload sort of does.

frank escarp Feb 26, 2019, 7:59 PM

#

does hot reload work in fortnite?

livid haven Feb 26, 2019, 7:59 PM

#

Instead it patches in the live code to call into its own DLL, if I understand correctly.

#

As far as I know, no one attempts to use hot reload in Fortnite.

frank escarp Feb 26, 2019, 8:00 PM

#

on PUBG we busted hot reload loooong ago

livid haven Feb 26, 2019, 8:00 PM

#

But we do use Live++ now.

frank escarp Feb 26, 2019, 8:00 PM

#

so eventually got disabled

#

uhmmm

#

i need more info about that

#

becouse im on the edge of throwing myself out of the window every time i need to tweak code

You're declaring a static function inside of a constructor.

So where do I call it?

Outside the Discord::Discord?

livid haven Feb 26, 2019, 8:07 PM

#

You're not calling anything. You're defining a function inside of a function. I don't know why you're trying to do that.

frank escarp Feb 26, 2019, 8:07 PM

#

@marsh garnet close VS

#

learn C++

marsh garnet Feb 26, 2019, 8:07 PM

Because, if I define it outside of the function, my DiscordRichPresence object is undefined.

if you want to do ue4 stuff, use blueprints

pallid compass Feb 26, 2019, 8:08 PM

#

Yeah dont do what i tried to do, your gonna have a very bad time

marsh garnet Feb 26, 2019, 8:08 PM

#

You can do DiscordRPC with blueprints?

livid haven Feb 26, 2019, 8:08 PM

#

You're not getting an error about your DiscordRPC because the compiler has given up by then with trying to make sense of your static function declaration/definition inside of a function definition.

frank escarp Feb 26, 2019, 8:08 PM

@livid haven how does the live++ work

#

does it hotpatch the function that changed?

livid haven Feb 26, 2019, 8:09 PM

Yep, that's my understanding.

can the demo version work in unreal?

even if only cpp file changes can be hotreloaded

thats good enough

livid haven Feb 26, 2019, 8:10 PM

pallid compass Feb 26, 2019, 8:11 PM

That sounds really nice

frank escarp Feb 26, 2019, 8:12 PM

#

then ill have to tell the office about it

#

everyone is sad that hotreload died in the project

livid haven Feb 26, 2019, 8:13 PM

#

Hot reload is just too difficult to maintain, IMO.

#

And as a feature that total noobs use? Even worse.

#

Because people don't know what it can't do and it's not feasible to have it detect the things it can't represent.

frank escarp Feb 26, 2019, 8:14 PM

#

it fails quite hard at modifying headers

#

wich makes total sense

#

the fact that it even works at all is an absolute miracle

#

i remember when hotreload didnt work on headers

livid haven Feb 26, 2019, 8:15 PM

#

Yep. Which Live++ won't really fix since it's just hotpatching functions.

frank escarp Feb 26, 2019, 8:15 PM

#

thats fine

#

most of the time what i want to iterate is 1 function

#

or add/remove visual logs

#

does it work multiplayer?

#

and in-game

livid haven Feb 26, 2019, 8:16 PM

#

Actually, I wonder how it explodes if you change a struct and have any of that struct, by value, in your source file?

#

I mean, presumably the Live++ created DLL will have the different memory footprint for that struct and the hotpatched function will now be trying to pass the old struct memory layout/footprint to the Live++ version that has a new memory layout/footprint.

vale silo Feb 26, 2019, 8:17 PM

polar hawk Feb 27, 2019, 12:08 AM

#

Don't work too hard I literally won't get it

maiden swift Feb 27, 2019, 12:08 AM

#

@pallid compass Well stop forgetting. Also take it to #lounge.

plush yew Feb 27, 2019, 12:08 AM

#

Meh

#

@next badger

pallid compass Feb 27, 2019, 12:09 AM

#

After Immutable and and Sion get at me first.

#

worn granite Feb 27, 2019, 12:09 AM

#

You auto-forward it to the company? @polar hawk ?

polar hawk Feb 27, 2019, 12:09 AM

#

I'mma leave this mystery unsolved

worn granite Feb 27, 2019, 12:09 AM

#

Fair enough

pallid compass Feb 27, 2019, 12:09 AM

#

Wait iv got it

#

Hes gonna throw them all in a lottery.

maiden swift Feb 27, 2019, 12:10 AM

#

Hey guys, guess what?

pallid compass Feb 27, 2019, 12:10 AM

#

btw @plush yew fair enough dude, i actually thought you had lost your marbles.

#

I take back what i said 10/10

maiden swift Feb 27, 2019, 12:10 AM

#

This isn't #lounge.

#

Get back on topic or leave it alone please.

#

OK good. Now we can move on.

pallid compass Feb 27, 2019, 12:11 AM

#

Is derived data cache not on topic in here?

polar hawk Feb 27, 2019, 12:11 AM

#

Is the topic of "I hate all general purpose channels related to UE4" on topic

pallid compass Feb 27, 2019, 12:11 AM

#

That is not a troll question, i guess its context to consider.

plush yew Feb 27, 2019, 12:11 AM

#

Tf does it make you download that for anyway

polar hawk Feb 27, 2019, 12:12 AM

#

Hear me out guys

pallid compass Feb 27, 2019, 12:12 AM

#

Looks like a component of some sort for some software?

polar hawk Feb 27, 2019, 12:12 AM

#

lets remove #ue4-general and #lounge

pallid compass Feb 27, 2019, 12:12 AM

#

pls no

livid haven Feb 27, 2019, 12:12 AM

#

@maiden swift Skyrip is on about UE4 including some kind of architecture software inside of the DDC folder.

worn granite Feb 27, 2019, 12:12 AM

#

I'd actually get work done, wtf is that suggestion

pallid compass Feb 27, 2019, 12:13 AM

livid haven Feb 27, 2019, 12:13 AM

#

We're trying to convince him he's mistaken and UE4 doesn't ship with any such software.

pallid compass Feb 27, 2019, 12:13 AM

#

He aint joking Sion

livid haven Feb 27, 2019, 12:13 AM

#

That's where all of this thread is about.

pallid compass Feb 27, 2019, 12:13 AM

#

I just had to eat my words.

polar hawk Feb 27, 2019, 12:13 AM

#

I highly suggest not boarding @plush yew's train

pallid compass Feb 27, 2019, 12:13 AM

#

Oh yeah it does not ship, but he did open it.

maiden swift Feb 27, 2019, 12:13 AM

#

@livid haven Yeah, I think I'm up to speed now. Pretty sure it's just a misunderstanding of course.

livid haven Feb 27, 2019, 12:13 AM

#

I told you it was probably just a common extension that was shared. Windows has a bunch of weird additional software like that these days.

#

Didn't know you had to install it afterwards though.

pallid compass Feb 27, 2019, 12:14 AM

#

Does obj not share the same extension are c++ compiled down before linking?

#

its object right?

#

extension as*

maiden swift Feb 27, 2019, 12:14 AM

#

Indeed. Seems like a weird coincidence. Not uncommon on Windows.

livid haven Feb 27, 2019, 12:14 AM

#

OBJ is both a 3d model format and also a compiled source file's format.

#

And probably a bajillion other things too.

polar hawk Feb 27, 2019, 12:14 AM

#

its also an obscure engine entity format

pallid compass Feb 27, 2019, 12:14 AM

#

Cant 100% recall the extension for object type files generated c++ before linking.

#

Ah so it is, gotcha.

#

lmao

polar hawk Feb 27, 2019, 12:15 AM

#

extensions are not sacred

livid haven Feb 27, 2019, 12:15 AM

#

Extensions are kind of antiquated shit.

pallid compass Feb 27, 2019, 12:15 AM

#

Yeah i have seen a few extensions used in different formats.

livid haven Feb 27, 2019, 12:16 AM

#

Like, what if multiple pieces of software support an extension? Do you... install another piece of software that opens the file and then figures out which of the other pieces of software probably really opens it? Gross.

polar hawk Feb 27, 2019, 12:16 AM

#

when starting a new ue4 project you should always change the config's .uasset extension to '.fuck'

pallid compass Feb 27, 2019, 12:16 AM

#

omg

worn granite Feb 27, 2019, 12:17 AM

pallid compass Feb 27, 2019, 12:17 AM

#

Go on immutable do it, you might even ship it knowing you

#

alex

plush yew Feb 27, 2019, 12:17 AM

#

Lul

worn granite Feb 27, 2019, 12:18 AM

#

I might even ship a ue4 project?

plush yew Feb 27, 2019, 12:18 AM

#

Good marketing scheme

next badger Feb 27, 2019, 12:18 AM

#

i think extensions are still used since header indexing is expensive

worn granite Feb 27, 2019, 12:18 AM

#

Gee, wow, thanks.

pallid compass Feb 27, 2019, 12:18 AM

#

If you ship a thing, il stop making CPU's in factorio and wasting my time.

#

Good deal?

#

gets to factorio forever

worn granite Feb 27, 2019, 12:19 AM

#

Does it count if the shipping was in the past?

#

Or do I need to ship a new thing

pallid compass Feb 27, 2019, 12:19 AM

#

No that is cheating.

#

Also this adds another thing to my list of things to learn

#

Learning to parse files and such properly from scratch.

worn granite Feb 27, 2019, 12:19 AM

#

Kindly define ship in this context

plush yew Feb 27, 2019, 12:19 AM

#

You can't learn anything from this @pallid compass

pallid compass Feb 27, 2019, 12:20 AM

#

You get on a ship and fail to England

#

sail*

#

God dam it.

livid haven Feb 27, 2019, 12:20 AM

#

So, when you think two characters in a show are cute...

worn granite Feb 27, 2019, 12:20 AM

#

ayy

livid haven Feb 27, 2019, 12:20 AM

#

... you 'ship them.

pallid compass Feb 27, 2019, 12:20 AM

#

🤦

plush yew Feb 27, 2019, 12:20 AM

#

But I think all cough UE4 cough characters are cute

Still wondering what other shitty things I can find
