@vague cypress Blueprint programing is like using premade things, that are comon to be used in programing.
Ex.. multipling two numbers, A and B,, is the same thing as saying,,,, add A, B number of times,,, or add B, A number of times (3x4 = 3+3+3+3 or 4+4+4)
vague cypress
ah i see
light coyote
so instead of writing the logic for doing that comon operation
vague cypress
oh thats handy
light coyote
in programing, they have libraries, wich have logic allready built in to it
light coyote
but in bluprints is even better, because you dont have to laern all the nomeclature(types of braquets, when to use wich,, what arguments does it use, do i have to put them all allways...),,,, therefore, same as you will not make a mistake in the multiplication logic in regular programing because its allready writen properly and you are not rewriteing it
vague cypress
oh cool
light coyote
Same with nodes, all logic inside them is ok, and it works,,, if something does not work, is your logic, not the boxes, nor writing error
vague cypress
That's pretty cool so then you don't make as many mistakes
light coyote
exactly, because they are less places in wich you can make one,,, simple as that
vague cypress
oh shit thanks
light coyote
but still, when learning you will make lots xD
in the sense of not knowing what to use
or things dont work as you expect, because you need other nodes
vague cypress
yh yh well im trying to work on a project. I was seeing if anyone would be interested in it but i just came accross like an ideas guy so i decided i might as well get atleast SOMETHING to work with and then people might take me a bit more seriously lol
light coyote
Everyone here has the great and best idea,, normaly is not as great, or it requires very hard work, or both
@vague cypress If you have a great idea and you are able to convince others of it,,, then it has chances to be one,, however, not a guarantee,,,,
But if you cant convince others, you still need to think more about it(not saying is good or bad)
vague cypress
no that's not what i meant... people liked the idea they just didn't want to help me because it doesn't benifit them which i understand
fading river
that's what I'm worried about, back in the day you could find people to work together on mods but these days everyone seems to be in it for the money

Hey im a complete beginner and i urgently need help with an issue. Im creating some sort of "museum" Project. I want to have 3D Widgets which are clickable (something like for more information click here botton next to an exibition item) when clicked it should cast another 3D Widget with additional informations (pictures and text) and a botton to then again remove it. It worked for me with a 3D Widget botton which can be clicked but i dont know how to cast another 3D widgid by useing the first 3D widget. Can somebody help me ?
radiant haven
is there a widget that makes smth only every 10sec instead of spamming
frail sail
Guys which is best CPU for build and develop in UE4?
plush yew
ryzen
vague cypress
@fading river Yeah... I have a great idea but people don't like the pitch i make
plush yew
idk, i use 2600, no lag, recompiles engine in 1400 sec
frail sail
3900 is better than 2600 right?
spark sonnet
Why does this happen?

Dose anyone know how to insert ad in a mobile game?
light coyote
@spark sonnet Note: you are multiplying it by 2 and then making it negative
midnight bolt
is there a hotkey for rotating by 90 degrees?
spark sonnet
Why should I use a timeline for a constant value?
light coyote
right click to create a key
you can make it loop
gives you a float output
use that float to rotate
spark sonnet
I think it still would do the same wouldnt it?
light coyote
you can make float go from 0 to 1
try it out
right click to create a key
with key selected you will see value and time you can set to
set it to 0 and 0
create another key
set time and value to 1
(time 1sec, value of the key 1)
up you will see loop,, select it
also you will se Length up there,,, set it to 1
spark sonnet
Made it now
light coyote
otherwise, the difrence of 4 seconds there is from you last key to the lenght of the timeline will act as a delay
vague cypress
hey guys i have a really retarded question but i need some help with it
spark sonnet
Its getting stuck at the same place again
:/
I just did this with another actor just rotating another axis. Why doesnt this work?
vague cypress
basically i have created a widget and an interactive button but when i click play on the game the cursor dissapears
i know im a retard
but i need help with this
spark sonnet
Can you send a picture of the code @vague cypress ?
spark sonnet
So you want to see the cursor?
vague cypress
thanks
spark sonnet
I cant talk right now, sorry
But you can put that blueprint in your players blueprint on BeginPlay
patent apex
hello, i want to use the โด character but when i paste it to unreal he gives me the wrong char
spark sonnet
Thanks. I'll try that
light coyote
this works, but is not completly uniform for some reason
Make sure the object is set to be movable
@vague cypress The button disapears because lets say you are in game
light coyote
you want a button that covers the full screen, and its invisible, when you press it you call the node Show Mouse Cursor
Simple solution
@spark sonnet The timeline is an incredible node, they are a gigantic number of things you can do,, it is very very extense,,, play arround with it
lavish blade
I've got 4 player starts for a local co-op game, a single object which keeps them all in view. However for some reason every player start gets its own camera actor and camera manager or something, whilst the pawn that's being spawned does not have a camera, any ideas ?
light coyote
Camera has to be in the blueprint of the pawn
There is a posess node
May be useful to your issue
Every character should have its own everything
lavish blade
But i don't want a camera per player controller/pawn since they will be on screen all the time
mint raptor
Does anyone know how to look up a reported issue on the issues.unrealengine site in Github to see what was patched and how? Example https://issues.unrealengine.com/issue/UE-73016
I've tried looking up the Fix Commit
light coyote
@lavish blade Sooo.. you dont want the camera to follow anyone in particular, but rather, the group then
Look up for camera follow in youtube
lavish blade
Yeah i followed that one but it does not seem to work (anymore)
spark sonnet
It did for me. Maybe you forgot something?
lavish blade
yeah maybe, i did change some of the blue print logic since there was alot of duplicated code
I'm gonna run through it see what i did wrong, thanks
@spark sonnet One thing in particular that did not work for me were the values in the gamemode, The moment i casted the gamemode in the camera object they were just empty again, like it was re instantiated
spark sonnet
Oh
I dont remember everything from it. I remember it took some time but eventually I got it to work

astral marsh
anyone knows how do i fix this error?
astral phoenix
is there some1 that can help me with this error? ๐
lavish blade
@spark sonnet I found the problem, The logic in the camera boject which gets all controllers and blends their views is executed before the logic in the gamemode (which actually spawns the player controllers) I fixed it with a delay right now but it looks bad. Does this ring a bell? Maybe you fixed it in a better way
spark sonnet
Sorry I dont remember @lavish blade But there should be an easier way to make the camera fit all the characters
sudden agate
@astral phoenix error says whats wrong.
lavish blade
@spark sonnet ah ok, thanks anyway, it woks now with a 0 delay node. seems a bit hacky but it works so i'm not complaining
spark sonnet
Glad you got it working @lavish blade
astral phoenix
@sudden agate i know the error says whats wrong but im asking how can i fix it?
sudden agate
by doing the opposite what the error says
spark sonnet
It says that the filename is too long, Could you try to shorten it?
astral phoenix
what file name?? idk what file its taking about? there is alot of files
cursive nova
It tells the exact file path
spark sonnet
The files listed in that log
cursive nova
So go follow that file path, go to the file name and give it a shorter name. aka, the opposite of what the error says.
light coyote
@cursive nova It actualy says the file name is too long
It says it several times
Chillax, people are trying to help
Errors, when strugling are a fucking pain
Everyone here is learning every day something new

He was probably just over thinking it
light coyote
fuckk, two images very similar an coments that confused me xD
light coyote
What happened betwen each picture ?
give more details
All i see is the same but diffrent xD
keen pawn
its literally
I change the floor
and its just smashing my environment lighting to bits
light coyote
have you built lights again and its like the second picture?
light coyote
Try turning off eye adaptation
keen pawn
duplicate the level
WHAM
persistent nuclear war outside
NO lighting change
just the textures
light coyote
nice solution XD
keen pawn
nah it messes it up even more
light coyote
Eye adaptation is the fact that your pupile dilates when in dark, allowing more light,,, so it tecnicaly, brightens darkness
light coyote
The oposite is also true, when to much light, closes, tecnicaly darkening
that is what i mean
light may be to intense, and when you turn eye adaptation off, it becomes aparent
light coyote
hahahahaha
keen pawn
i want to have a darker warehouse
but everything lit correctly
but it almost looks as if theres an emmisive
light coyote
yes
Things just look to burnt, light is to intense, i think
If you havent used a post process volume, maybe is the time to do so
keen pawn
there is one on now
light coyote
yes
light coyote
yes yes
keen pawn
ive tried adjusting the exposure
light coyote
go to global ilumination, turn down gamma,,, you have to enable it first if its off
light coyote
where is the post process ?
keen pawn
all around ๐
I've gotta go home now and give up for today
but ill try again tomorrow
thanks for the help though dude ๐
light coyote
no worries
whait
maybe is not set to unbound, so you are not seeing the changes cause you have to be inside
keen pawn
?
light coyote
check it
you can turn down gamma, gain, increase oclusion between all objects in scene to give more depth, as well as blurr in distance et....

hey guys, kinda of a weird question, is there anyway to attach an item to multiple sockets?
For example, my character is holding a 2 handed rifler. There is a socket on the right hand that the rifle grip is attached to
what would be the best way to attach the left hand to the barrel grip?
grizzled axle
I think Hand IK is what you are looking for
plush yew
maybe multiple sockets isn't possible for this then haha, but any solution for this is fine
ok great thanks
ill do some hw on that
grizzled axle
never done it but I have to do it soon too ๐
plush yew
yeah IK seems like a really nice tool that I should spend some time learning
light coyote
I havent looked in to that to much either, but..
maybe you can copy something from the default fps template
๐
plush yew
actually it seems like i wasnt too far off, I guess I will gave to use multiple sockets but this time the rifle will have a socket for the IK instead of the second socket going on the left hand
grizzled axle
there was tutorial on epics unreal documents somewhere
plush yew
https://zaggoth.wordpress.com/2019/01/26/ue4-tutorial-the-right-way-to-do-left-hand-weapon-ik/ i found this one which looks promising and adaptable

Hey, does anyone here know about creating plugins? I'm trying to mod a game I do not have the source to. We have been able to inject cooked maps with dummy blueprints that can call all the games functions but we cannot create new CPP classes as they'd need to be serialised into the shipping.exe. what I was wondering is: could I create a bpfunctionlibrary plugin and then call the functions from that. Every attempt to create a plugin to do so gives me the error can't load x plugin cause it can't find x module

Why when i use previewing Android Es2 . All lights are gone ?
How to fix it
I used default point light
cursive nova
is there a way to set actor rotation? But not instantly?
light coyote
@cursive nova What do you mean exactly ?
plush yew
Where support
cursive nova
Like I'm trying to implement directional rolling and I can get the last movement input vector and then use that to set actor rotation for the third person character and it works, I have directional rolling but it's instant. Doesn't look natural, he just kinda jerks to the direction instantly.
light coyote
Because you are literaly setting it at that instant to that position
use a timeline
cursive nova
Yeah, I know. I just don't know how to do it any other way.
light coyote
Create timeline
Doubleclick it to open it
Create a float function (f icon)(the name you give it, it will be the name of the output float you will use)
Once in the float track
Right click inside and create a key
Having that key selected, you will see up, you can asign a value and a time to it, set them both to 0
Do the same thing, but this time set the value to 1 and the time, to whatever time the roll will take
Now you will find up there, Length, is at 5 by default,,,set it to the same time you decided the rolling will take
What you have now is a float from 0 to 1 that will reach 1 at whatever time you chose the roll to take
You can use that if you want, but in this case you are only really intrested in the update output node
It will give you flow during the time you chose, and after it will stop(plug what ever trigers it on the play from start input)
That way it will alwais start from the beguining
real mesa
If I was creating a open-world game, would the blank template be good?
light coyote
Yes, chose a template that may have something you may be intrested in using
You can alwais delete what ever you dont want
@cursive nova Now you have a temporary update to wich you can plug the set location to
use a lerp vector to lerp between the start location, and end location
real mesa
Also, If I was trying to import a car or low poly character I made from blender. Would I export it as fbx?
light coyote
@cursive nova And plug your float to the lerp,, it will act like a percentage
Yes, FBX is ok
cursive nova
Thanks, I'm going to try this out and see if it works
light coyote
It does
You just need to give it the proper information
Or the proper location node

Hey, is there a function to get an ascii value for a text character in BP?

Ha, ok answered. They made it too simple and literal for me to find it easily. "GetCharacterAsNumber"
Ok, so is there something built in that does the reverse?
scarlet birch
nevermind
real mesa
Why when I try and import a car I made from blender, it says lighting needs to be rebuilt
.
What does that mean?
silent frost
Terminology might be wrong, but within the viewport, at the top, you'll need to "Build Lighting only", to resolve that. It's just the renderer needing to rebuild the lighting.

does anyone have 3ds max here?

@silent frost I rebuilded the lighting, but it still gives me the error.

@real mesa Hmmm, that's odd. Any error messages or such? Not entirely sure why that wouldn't work. Maybe someone else might be able to help too. Sorry, not much help ๐ฆ
real mesa
I'm going to reboot UE4 and see if that does anything.
@silent frost I got this once I rebuilded the lighting
silent frost
Need to check your UV's of your model, in Blender. If all looks OK, and visually it looks OK in UE4, then I wouldn't worry too much.
As it mentions, you can enable Error Colouring and it'll highlight visually where those errors are.
Within UE4
real mesa
How do I check UVS in blender?
fading river
Can anyone recommend a good hello-world tutorial for somebody who already knows programming? Like setting up the map basics, how to create some premade actors and materials and such. I used UE2 way long ago so I know the concepts I just need to learn the interface and differences in the new engine.
real mesa
@silent frost
silent frost
@real mesa Unfortunately I don't know Blender, but there should be a UV layout or editor tool within Blender.
@fading river - YouTube will have some useful tutorials. Check out Virtus, he's got a lot of useful content.
next badger
@cedar trellis Unfortunately, if the file type is COPY - that means UE4 crapped the asset and it can't be exported anymore...only way to solve this is bake the texture to another asset...one of the mind blowing fails of UE4 ever known...

Hey guys? WHat do you think is happening if it gets stuck at 20% while building a simple stage? It's been working at it for hours and has been caught at 20 for hours. It's just a simple stage with only basic atmosphere and box brushes, and I did just reinstall the engine
Unreal is currently using most of my memory, but there's like zero CPU dedicated to the process
Apparently it's stuck at 'building texture streaming', whatever that is
Any advice?
v4.22.3 on win10
naive lotus
Does anyone at least have a reference for this kinda thing?
forest dock
It would be a nice quality of life thing if I could have the scale in the editor show meters diameter for the selected's dimension instead of a relative scale to how large it was when it was imported.
Is that possible?
serene sorrel
@naive lotus so its not building shaders? that takes forever sometimes
naive lotus
I don't think it is, all that this level has is an Atmos Fog object, a sky sphere, a Directional Light, a bunch of box brushes, and a default player spawner. That's literally all I put in this project besides the starter content pack.
forest dock
I can vouch that this part normally takes a lot of time, I've had it halt on building those for a couple of hours at 20%, but never as long as 20 hours. Did building the same stage work for you before but doesn't now, or is this a consistent issue with your build?
serene sorrel
its probably borked if its taking longer than an hour imo
i hate static lighting and never use it in my projects so that removes a lot of that wait
My I7 @ 3.8ghz takes 5-10 mins just turning OFF static lighting, it stats at 45% on the loading project screen, then when it gets in it recompiles all the shaders again
naive lotus
Wait wait hold up static lighting takes LONGER to build???
whaaaaaaaaaaaaat
I thought the only reason I was told to use static lights was so it would SAVE resources!
This tutorial author is a fraud
maybe I'm overreacting. Sorry. Frustrated lately.
serene sorrel
no, just initially it has to recompile your shaders to NOT have static lighting in them ๐
after that its much quicker yeah
unless youre targeting potato computers i dont really understand static lighting
naive lotus
huh... would explain why I was able to do it before...
Okay. So, I just sent Task Manager to assassinate it. To fix this, I turn the sun into a stationary light? or a movable light? And then try building again
naive lotus
I'll try that too, all right
Are there any other fixes you can think of that would optimize Unreal Editor for a laptop?
serene sorrel
what sort
Best way to optimize unreal for a laptop? Throw it in the bin and buy a Ryzen 3900x ๐
Do you have active laptop cooling? I Find that helps a LOT for mine
naive lotus
I mean, it's not like my grandma's computer but it has a hard time with max graphics.
HP Pavilion. 16 gigs ram, Intel UHD graphics 620
serene sorrel
They thermal throttle to shit performance very easily intel based laptops
naive lotus
Active cooling fan yes
serene sorrel
do you use laptop monitor or external
naive lotus
built-in monitor. Hah, wish I had space for a dual monitor
Unlesssssssssss
maybe I could use the TV's HDMI
serene sorrel
Yeah im getting a ryzen 3900x or 3950x whatever comes into stock first
4 core laptops dont really compare these days to what is available
naive lotus
yeah. Honestly I wanna build an actual battlestation computer sometime, but eh, I'm broke.
serene sorrel
Unreal Engine seems even slower to me , but granted I was using desktop computer 2 years ago compared to this gaming laptop im using now (same specs tho)
this laptop only has 16gb ram vs 32gb ram my desktop has
naive lotus
The day I get the money to get a good computer is the day I learn to build them myself. I'll even try to make it look like an old-school arcade cabinet but with modern guts lol
serene sorrel
yeah make a good game for potato computers then, buy your new comp
naive lotus
Good plan lol
Actually, that's kinda why I got into Unreal, there's a guy who's paying me to learn unreal. Granted, getting paid in "IOU a share in the game's profits when we actually ship something," but still
I know it's a little risky, but hey, who even pretends to promise to pay someone to LEARN these days?
Not like they can take self-taught skills away lol
serene sorrel
well if youre dedicated enough im sure even people with average iq could make something worth buying in UE
naive lotus
Yeah, hopefully it'll go well.
You know, I've always had some interest in game dev, just, when I thought of it, it was usually 2D stuff. Things I could prototype on paper even.
crap, now it's stuck at 45% on just loading the editor
serene sorrel
if you dont have revolutionary plans, then what UE or other engines can do for you doesnt really require much knowledge in the way of maths or 3d engine knowledge
its only when youre pushing the boundaries and you get into engine development that you will need some higher level skills.
naive lotus
Yeah, that makes sense I suppose. Though, I find that learning math is useful anyway.
had to learn some anyway though, took way too long to figure out that if I want a single number that Unreal calls that a scalar
naive lotus
Hey @serene sorrel ? Just after I made that change, Unreal isn't opening up, you experienced that one before?
serene sorrel
its stuck on 45% ?

i had once tried make AI chase me but when i tried to run it, it only chase to spawn point even the code same as youtube one. what's the reason behind of this?
blissful trail
Is there any way to fix physics objects going through other objects at high speeds ?
cloud cobalt
Physics substepping
blissful trail
Whats a good max substeps and or substep delta time
cloud cobalt
Literally depends on your game
Obviously the highest the speed, the more substeps required, the more demanding it will be
blissful trail
I turned max substeps all the way up and it still goes through
wary wave
if you're having problems with a large number of substeps, and your framerates are fine, you may want to question the sanity of what you're doing to start with
regal mulch
@blissful trail You could try to combine this with a trace in Velocity direction.
serene sorrel
usually , if you had full control over physics, you would just increase number of physics ticks per second until what you want works
regal mulch
From last Frame Location to Current Frame.
If that trace hits, your physics object went through something and you can manually correct it
serene sorrel
so you either increase physics ticks per second, or decrease speed of objects
also increasing the width of objects is another workaround
paper dust
That trace is what PhysX "continuous collision detection" should do for you automatically. Can't that be enabled in UE?
serene sorrel
so rather than test against a thin wall, its against a thick wall
regal mulch
The CCD setting in UE4 doesn't solve this
I had this ages ago for a Physics Object. It randomly went through walls, even on lower speeds.
We ended up increasing the wall width, which I think helped, but it was still happening
serene sorrel
can you keep physics ticks at a constant per second in UE4?
regal mulch
So basically lockstep stuff?
serene sorrel
the framerate issue with physics engines is well known, and if you need it 100% accurate then you need to be doing the physics at a high-ish update rate, no matter what happens to actual framerate
so "one second" of game physics could be taking more than "one second" on a computer, game time runs slower than real time, but at least you dont get physics bugs
dont know if unreal engine gives you that power or not
regal mulch
I don't think you have control over that in UE4, at least not easily.
You can enable substepping and that's mostly it
serene sorrel
yah yah
regal mulch
So if it's really important, that this object behaves properly, I would suggest checking if you can setup the movement vector based and turn off physics.
serene sorrel
is there limit to substeps too or?
regal mulch
Yeah
serene sorrel
that sucks
regal mulch
Either num of substeps or, half sure, min tick time
serene sorrel
i mean you should be able to control the physics update rate imo
lusty carbon
How can I make my actor instance not tick when set invisible in the level?
and only tick when visible
regal mulch
Just turn tick on/off when you hide the actor
wary wave
@lusty carbon - nobody answered that question for the same reasons they didn't yesterday
there is literally a node for it
'Set Tick Enabled'
cloud cobalt
@serene sorrel For that matter, we had the same problem of high-velocity projectiles and we simply went with collisions tests on tick using a trace over the distance that next tick would cover
lusty carbon
" nobody answered that question for the same reasons they didn't yesterday"
which is what?
too easy an answer for them?
regal mulch
More like you could have found that answer with a second of googling. :P
wary wave
too easy for you to find the answer yourself
serene sorrel
@cloud cobalt id pretty much consider any physics engine in any "engine" to be for graphical stuff only, if it "matters" to gameplay it should be done precisely
cloud cobalt
Game physics suck generally, and PhysX is the most terrible of game physics engine, so work around it
regal mulch
I know you can find that answer in a few seconds.
cloud cobalt
I mean, UE physics are basically unsupported in multiplayer so ๐คท
serene sorrel
they are?
cloud cobalt
Well yeah
regal mulch
@lusty carbon https://i.imgur.com/8mYN2Fd.png
serene sorrel
ive seen multiplayer games with physics that work, i dont know how reliable but apparently they work
regal mulch
ยฏ_(ใ)_/ยฏ
cloud cobalt
PhysX isn't deterministic, so you can't do rollback/replay reliably
serene sorrel
isnt movement in unreal all done using physics
regal mulch
2 clicks later and you are at the node that ambershee told you about
@serene sorrel Vector Math.
cloud cobalt
No, movement generally doesn't use physics other than collision
regal mulch
Straight up calculating Velocity by yourself
And applying it to the root of the actor
paper dust
Movement is typically done with the CharacterController, which does its own (simplistic, stable) physics.
regal mulch
And then collision is done via physics, but the movement itself does not
cloud cobalt
If you want to use actual physics for movement in multiplayer, you basically have to do it on the input-controlling client, and have the server trust it blindly since there's no way it can ever reproduce it accurately
Which sucks
regal mulch
Even then you can't do that really
Cause you can't really rollback and shit
Cause you can't save the moves easily, you'd need to save the whole physics scene
wary wave
hence 'trust blindly'
regal mulch
Just don't do Multiplayer Physix
wary wave
Redout is an example of a game that uses PhysX in multiplayer
serene sorrel
well thats what i mean, the movement is governed by collision, which is physics , so?
wary wave
they have all kinds of weird server side checks to try and make sure nobody is cheating etc, but it's otherwise all client side
regal mulch
@serene sorrel Physics doesn't say it should move into a specific direction at a specific speed
It only checks for a collision and returns the details about it
serene sorrel
jumping?
regal mulch
Velocity
serene sorrel
so what part of the physics in UE is unreliable then
cloud cobalt
UE4 built-in character jumping doesn't use the physics in any way
regal mulch
If you turn off collision you can fly around without any physics
cloud cobalt
"Simulate physics"
serene sorrel
ah
cloud cobalt
Everything that switch does will be broken in MP
regal mulch
99% of the time
serene sorrel
yeah, no lockstep does that
regal mulch
Correct, chaos could fix this
serene sorrel
ah thank god im not making a RTS this time around
regal mulch
If it's not about player input that drives the physics, then you could get away from having the server do the physics stuff
wary wave
most RTS don't use any kind of physics whatsoever
regal mulch
And letting the clients interpolate the location replication
wary wave
a lot don't even use collision
serene sorrel
i implemented lock step in unity, wasnt that bad except you have to do all the math yourself
cloud cobalt
The general advice is to avoid physics in MP games alltogether
serene sorrel
was using fixed point math too
regal mulch
@serene sorrel Problem with UE4 compared to Unity is that UE4 has a lot of stuff given that you'd have to adjust
serene sorrel
because floats are unreliable
Nah unity is not geared for lockstep at all
it'd be literally the same doing in both i feel
its quite weird no big engine gives you the lockstep method with fixed point math + interpolation, wouldnt take that long to implement
wary wave
it's not many games that want it, tbh
regal mulch
UE4 is basically the Engine to make UT with and that doesn't need Lockstep physics
serene sorrel
mainly high unit games yeah
wary wave
those that do tend to want their own engines
serene sorrel
sure not many games use it but its literally a necessity for a proper RTS
regal mulch
Yeah you also don't do proper RTS with UE4 :D
serene sorrel
and some physics based games
serene sorrel
yeah just consume 4MB/sec bandwidth ๐
regal mulch
RTS games also used P2P networking to handle all the arrows and shit that otherwise has to replicate
wary wave
generally speaking Internet connections tend to be fast enough to keep up with the simulation fairly reliably
serene sorrel
planetary annihilation comes to mind
regal mulch
Which UE4 also doesn't have
serene sorrel
RTS games used P2P back in the day because of dialup modem support mainly
regal mulch
If you have a game where you can have 50 archers that all shoot at once, then this will still f up people internet if you are unlucky
Needs other forms of optimizations then
serene sorrel
Adding P2p is unnecessary complication for games to deal with low bandwidth
wouldnt be used these days
regal mulch
Yeah, what does the Age of Empires 2HD remake do?
serene sorrel
no idea
probably the same, Blizzard kept SC on p2p for the lifetime just because it was mangled code and hard to change
even though it has downsides with authority
i think SC2 either routes it all through host or blizzard servers themselves
but yeah without lockstep, you move 50 archers then you need to update all clients about the 50 archers. with lockstep its like 4 bytes to say the same
wary wave
AoE2 is peer to peer
serene sorrel
command: "move selected units"
location
wary wave
as for '50 archers' - depending on the game you can get away without networking any of them at all ๐
Total War games don't
nobody notices
serene sorrel
what do you mean
wary wave
unit of 50 archers, none of them are networked
serene sorrel
i think im missing the joke
wary wave
the only thing that's networked is the state of the managing actor
the individual entities are totally client side
serene sorrel
right, but total war is different because 50archers is literally 1 archer
its "1 unit"
wary wave
it's more than their entire simulation is deterministic in the first place
serene sorrel
so its locksttep too?
wary wave
in theory the only thing that needs to be replicated is player input
I don't know that it's using lockstep, I wouldn't be so sure
serene sorrel
yeah you can only do that reliably with lockstep cant you, i dont know of any other methods
and on top of that, you have to throw out using cpu floating point
at least if you want extreme reliability across platforms
Hmm the most popular water plugin on the marketplace doesnt have underwater ?
cloud cobalt
Maybe ? Find one that does instead
Underwater isn't exactly a commonly needed feature
serene sorrel
A lot of landscapes have water, only seems natural if there is water you can enter it
cloud cobalt
Going underwater in video games is not that common, natural or not
It's a lot of development time so your gameplay has to really need it
If you're doing Sea of Thieves, it's granted that you want it, if you're doing Call of Duty, maybe not so much
If you're not doing a first-person game, maybe even less so
serene sorrel
Far Cry was doing it in 2004
wary wave
Far Cry is Far Cry
serene sorrel
Ark / Rust
wary wave
a lot of games may have open water, but still not allow you to really go into it
either you wade in to waist height as so the camera never clips, or you might just die etc
other games just avoid it entirely
some games keep the player character glued to the surface even when swimming, hehe
cloud cobalt
I think I have a total of two games on Steam where you can go into water, one of them being Subnautica
cloud cobalt
Look, if you want to say that some games have a hard requirement of underwater gameplay, that's agreable
Not everyone does open-world shooter though
serene sorrel
its literally a necessity for any survival based game in my opinion
Subsistence, 7 Days to die, have it too
wary wave
pretty sure plenty of survival games don't have it
cloud cobalt
Then work on underwater gameplay, or pick another game genre
I mean, I wouldn't touch open-world survival games with a 50ft pole as a developer, largely because of stuff like that
wary wave
tbh, underwater stuff isn't that hard to do these days
serene sorrel
because engines as they are now arent really geared for it?
procedural terrain in unreal still looks like its a dream
wary wave
plenty of games just don't do it because it doesn't add enough to warrant development time
serene sorrel
i dont think its difficult to add basic water based gameplay, in UE you could do a physics volume
then its just a little shimmery refraction shader and youre done
cloud cobalt
Then do it
serene sorrel
i will, just find it strange the most popular plugin doesnt have it, apparently its been planned for 3 years
cloud cobalt
And I'm telling you the fact it's not supported is largely because most water users don't need to go into it.
So do it yourself or wait for it
serene sorrel
yeah, those are the options
wary wave
..or pick a different plugin
serene birch
it makes sense : doing underwater is a lot of extra work, so the plugin that does NOT do underwater can spend more time making the water look good, and as a result becomes the most popular/well rated one for that
serene sorrel
i just find it strange they dont have at least some basic underwater stuff in it
wouldnt even take long
cloud cobalt
It's not strange if they don't give a shit

Yup lol

And idk
serene sorrel
@thin tendon 10
thin tendon
Thanks mate
honest vale
I hope they're not shadow casting ๐
serene sorrel
thatll be easy.... just as soon as raytracing is mainstream
I feel like they want to move us to cloud based gaming rather than all of us having gpus soon though
the positive of which is that cheating in online games will be nearly impossible, downside is latency and not actually owning anything any more, just renting
serene birch
technically
you buy AND rent at the same time ๐
you still need to buy the games ๐
serene sorrel
buy the game rent the service yeah
(*) Game only available while service is operational
theres some upsides in some ways to cloud game, much harder to cheat, much harder to pirate.
I dont think piracy is such a bad thing though, i think most people that would buy your game do if its any good
thin tendon
I would argue piracy is a good thing. If people are going through the effort to steal my game. It must be worth playing
serene sorrel
its hard enough to get people to play your game in the first place, so yeah
anti piracy stuff only helps EA type people that push out shit products and want regular sales of Madden 19
thin tendon
I agree. If it were something that happened to me. I would probably let it go just for the word of mouth factor and getting my game out there more
serene sorrel
I do like the fact for multiplayer games it makes cheating nearly impossible
so i may consider cloud gaming for multiplayer games since there is already lag anyhow
thin tendon
With my game I'm actually focusing on a multiplayer similar to minecraft where you invite friends in. This way if people cheat its up to them I don't have to address it.
serene sorrel
yeah exactly
its not like Rust where you spend days building a base with secret rooms and then an ESP hacker comes in and loots you easily
thin tendon
Exactly. The advantage of a friend system. Is if you don't want to play with them unfriend them.
serene sorrel
Just knowing everyone is legit is a big win for multiplayer games imo
plus you already deal with latency, though it will be differetn since client prediction often hides it where cloud services cant
I would like to see if competitive FPS is possible with cloud gaming, without annoying those who know what low latency is
thin tendon
I always had a good idea for adressing cheating if I ever get my company big enough to worry about it. Just challenge people too cheat and break the game. And then give them in game rewards for sharing how they did it.
floral aspen
I have some real problems today with unreal engine, I get a constant blue loading bar in the top. Anyone else getting this?
serene sorrel
@thin tendon yeah except that doesnt work with games like Rust where people are literally paying to cheat
$30/month
its a business model to make hacks when people want to pay for it
thin tendon
Another good way to ruin payed for hacks. Is set up your levelling up system in a way. Where hacks aren't needed because if people level up enough they won't need hacks.
serene sorrel
yeah, Rust and Ark are different in that they wipe regularly
ie restart
so that idea is out the window too ๐
thin tendon
ohh I hate that idea
serene sorrel
well its actually preferable in the way those games are
thin tendon
Wipes are soo bad. Your punishing players for playing
serene sorrel
yeah, but wiping after a month isnt so bad, everyone gets to have that fun early game grind again
floral aspen
like d3 new seasons ๐
thin tendon
If I was ever going to do wipes. I would set it up in a way to say once server is 90% capacity auto wipe generate warnings at 70%
serene sorrel
If you havent played Rust , stay away from it because its addiction level is high
thin tendon
I tried Rust way back in its early access and didn't like it. Which is funny because now I'm making a survival game
thin tendon
The one I really like is 7 days. Because they give you the option of single player or multiplayer
serene sorrel
yeah, im a big survival game fan, have all the best ones
thin tendon
Yeah same. I love the genre.
serene sorrel
7 days is good but its stagnated badly for 3 years or so now
thin tendon
yeah alot of games do that these days
serene sorrel
the last update took them a year and barely changed anything
thin tendon
I'm actually working on an Australian themed survival game. And its crazy man I patch almost every week with new stuff
serene sorrel
ive got my moneys worth with the game so its not like im saying they need to do anything really, its just stagnated

hey guys, im having kind of a minor error. Right now, I have a system that gets the gun information from the player's currently equipped gun. Everything works fine, however when i jump out of play mode i always get an error log saying the gun object could not be found. The game finds the gun asset though just fine, I just believe that on the first call of that function, the player hasnt fully loaded in yet and therefore the gun isn't found in the first frame. This just leads to an error message in the log, is there any way i can squash these errors so i dont have to see them every time i play?
wary wave
you're probably getting it via current player controller or something similar
GetPlayerController(0), or a similar function
this also implies you're not doing any validity checking either
grim ore
validate all the things, every get should be validated every set should be validated every access should be validated. If atleast 40% of your nodes are not valid checks you need to change that to 60%!
hoary marsh
@grim ore Hey, thanks for your videos. Helped me a lot and keep up the awesome work ๐
grim ore
๐ awesome possum, glad you found some useful. I hope to keep it up if I can remember what I was working on lol
bronze plinth
Sorry to bother but again with my question, if i have the option to do the same thing either through BP or through Code
Which one is better or its the same?
empty yoke
With perforce can you go back a revision of a blueprint and make that the master
grim ore
@bronze plinth if you can literally do the same thing in BP and Code then you do whatever you feel like. There is no better there is only different. There may be better for some things in some circumstances but you would have to test that on your project under your settings.
with that said some things are easier to manage in one of the other, UMG widgets for example have the nice layout editor in the engine so while you can do it all in c++ that would be weird. High end math or recursion or data processing might end up quicker in C++ depending on the data and what you are doing.
bronze plinth
yea
makes sense okay :D
the thing is I am pretty new but currently learning from tutorials which are all BP and was questioning myself am i wasting my time
I am pretty decent at C++ from my software engineer background but feel like I need to learn the UE Api
grim ore
pretty new to what ?
lilac wedge
why does "Addworldoffset" not work when "ReplicateMovment" is true?
empty nexus
Hey folks. New guy here. I've been a developer for a while, and am very familiar with C++, but I have a few design questions. Would anyone have a spare moment to listen and offer some advice?
I am helping a colleague develop an RPG. I was wondering if you all think it's generally a bad idea to separate the logical data and methods of a player character from the Actor/Pawn?
I want to make a clear separation between the graphical representation of the actor and the logical data and operations.
grim ore
there is nothing wrong with that, that is a standard MVVM setup
it might be a bit weird tho as the engine is designed more around separate entities that are wholly encapsulated tho
but things like blueprint components you can attach to the pawn/actor to give it the data and logic are not odd. Something like an inventory would work for this idea
empty nexus
Cool. I am trying to basically expose certain values and functions (mostly callbacks) through UPROPERTY and UFUNCTION to give the creatives everything they need to be able to do their Blueprint coding, while I just provide the logical data and battle engines and such behind the scenes. Basically just give them enough to make graphical decisions. Like I don't care if the party runs single file or spread out. So I will provide the data about the party and it's workings in C++, and give them the ability to implement that party graphically however they want.
So I have them linked to each other with a pointer. Basically the actor has a pointer to the logical character, and the logical character has a pointer to the actor. My party object points to each logical character, lives in the GameInstance, but it instantiated in the GameMode using a factory design pattern that reads data from UE Tables. Does that sound reasonable?
wary wave
I'd argue that the logical and graphical components are already separated through the use of components
wary wave
assuming the input is a position
left citrus
I believe so, yeah
empty nexus
@wary wave Can you elaborate? I want to hear more =). Because the way I see it...for example, I don't want to just include all of my player data (like HP, MP, Experience, etc) in the same class that handles camera control, collisions, meshes, etc. Which components do you mean?
@wary wave Like attaching components to other actors?
wary wave
well, the character is in itself composed of a number of components by design
(plus any additional components you may wish to create)
grim ore
have you used Unity before @empty nexus ?
wary wave
Movement Components (logical) and Mesh Components (graphical) are already there
it would not be unreasonable to have components specific to your game for handling certain behaviours, e.g. a 'HealthComponent' as a simple example
grim ore
not unreasonable just highly highly uhm... cant think of the word lol
like most people wouldn't add a component just for stats but yep you can
wary wave
I've seen games implemented this way and it's just fine
empty nexus
Very little. I usually code my own engines in OpenGL or another frame work like Phaser.js.
grim ore
yep it's more "advanced" i guess might be the closest way of saying it
customizeable? ADDish? lol
empty nexus
I am just really anal about my data structures lol.
grim ore
not in a negative way, don't get me wrong, it's just not as "basic" as most games tend to be
see even basic is not correct
empty nexus
So the way I am doing things is not "wrong" per say? Including which objects I have certain data living in?
grim ore
it's like you can do the game one way and it will work and be fine and take less time to plan out, just gung ho that sucker or you can structure the entire thing into a set of legos from the start and in the end they both work the same
wary wave
I would probably go the component route since it's already neatly encapsulating data
grim ore
so nope what you are doing is not wrong the engine is designed that way as it is now but for higher level stuff
empty nexus
I am just all about maintainability. The easier I can navigate code, the safer my sanity will be.
grim ore
like a camera as a component is built in because you can just plop one in to something and have a camera work and be all nice and happy in it's own component with it's own settings.
empty nexus
I like this idea of components though. The question is, can I attach components programmatically in C++? And what type constitutes a component. Like a UObject? Or is there a specific type I should be using?
wary wave
Component is a class / type in itself
and naturally they can be created programmatically
you should probably spend some time with the engine and come back
empty nexus
That's the plan. Thanks for the direction though!
wary wave
(since these questions are really quite basic and you'd get a much better impression)
wary wave
just opening up something like the basic first person template demonstrates how some of the core components are integrated
grim ore
Your idea is a good idea btw, just not a normal one for most people to approach when starting ๐
empty nexus
I did =). I have been messing around with the ThirdPerson template.
I have figured out how to do and structure most things. Just trying to figure out the best way to do some things.
Like "best practices" you know.
A lot of these things I am just used to doing myself. So here, I'm just trying to figure out how to fit my general practices into this engine.
grim ore
heh... watch some of the unreal fest videos from this year and you will find best practices are whatever works for the studio lol ๐
empty nexus
lol that's true.
wary wave
...I'm not sure some of those practices are necessarily ones I'd recommend
but whatever works (or in some cases, doesn't, with respect to the Unreal Fest videos)
empty nexus
I am just neurotic about design. I'm not comfortable with moving forward with the game until I am happy with how I am representing data.
But thanks for the tips. I will explore a little more and come back with questions. Thank you both for your insights!
I hope I didn't annoy anyone.
Oh cool! I see! ActorComponents.
grim ore
no annoying here ๐ was a good question
I never thought of making stuff so granular to be honest, and stuff like stats epic has systems in place (Gameplay Ability) they use to handle that
empty nexus
Thanks for that. I always feel nervous when I enter a new group of developers. I tend to ask a lot of questions.
And yeah, that's the hard part when working in a new engine. Figuring out what functionality already exists, and what needs to be made.
grim ore
well in here as long as you are nice and actually wanting to participate and ask questions most people seem to be more than happy to help
light coyote
Woah, i missed some heavy talk.
I cant really contribute, but it was worth reading ๐

left citrus
just me or is this going flip side?
empty nexus
Nah. No need for that. Just sometimes need to hear from some veterans that my ideas aren't completely crazy.
plush yew
need some help with animation rotations. Right now I'm using orient rotation to movement. Normally this is fine because I have an aim offset for the upper body so my pawn can be moving in (almost) any direction and i will still shot where i'm aiming. I really like the way it looks too (which is why i don't want to switch off 'orient rotation to movement' because then my character just looks too static and unnatural). My only problem is my aim offset only turns in a 180 degree arc, so I can't really run while shooting behind me.
I did try to run this through BP and got some things to work kinda, but what ends up happening is the BP rotations seem to fight with the 'orient rotation to movement' setting, so this means my character keeps flickering between strafing backwards and running forward while aiming to either 90 or -90 degrees to the side (like in the picture)
any ideas for solutions? I was pretty proud of myself for being able to figure out how to turn my actor based on the difference between aim offset and actor rotation, just seems right now I'm fighting with the editor instead of the math
autumn elbow
What am I missing here.
I spawn an actor, now i want to set simulate physics off
I have an actor ref returned from the spawn, set simulate needs a primitive component ref
grim ore
it would be on the root of the actor for example, or a mesh, or something that inherits from the primitive component (the actor itself is not a component)
so it would be drag off the return value, get whatever is simulating physics, set simulate physics
grim ore
yep so spawn actor -> get static mesh -> do whatever
autumn elbow
oh.. yea.. I can't get static mesh.
grim ore
you sure?
oh wait
yeah since the class is not at design time it won't know
I think there is a root function that would work from the actor
autumn elbow
hahha i am soo confused
autumn elbow
tried that
grim ore
yep your gonna have to cast in here at some point or use a blueprint interface
ok so... the problem is the Spawn Actor has no idea what you are spawning so the Return Value is going to be a generic actor
so you need to either cast that actor to a specific class so you can get the right property from it (static mesh in this case) or you need to just get the root component (the first thing in the components tab, static mesh in your example), and then set simulate physics on it
https://i.imgur.com/GEWJARp.png for example for the casting to Primitive Component
autumn elbow
Thats weird because i'm telling it which class to spawn
grim ore
you aren't is the problem
you are providing it a class thru a variable
and that variable is variable.... heh
so the actual node has to be generic since you could be spawning a house or a car or a cat or a flaming sword
autumn elbow
hmmm interesting
grim ore
if you had the actual variable fixed in the spawn actor node, the drop down itself, it would configure the output to the class
autumn elbow
i seeeeee
ok.. lemme try
yea that worked
gooosh... feels like the long way around lol
Thanks!
empty nexus
What do I do when changing a class causes the editor to crash and refuses to launch again?
grim ore
changed in BP or C++?
C++ you can delete the intermediate and binaries and compile again after fixing it, in BP maybe move the .uasset file out of the content directory to get the project loaded again but moving the file back might crash it again...
light coyote
Ue4 also makes autosaves
maybe its thi first thing you did today, and dont lose anything

C++. Okay. I had only deleted the binaries, I'll try deleting the Intermediate files too.
Lesson learned. Compile before adding new classes.

It is but not that way
forest dock
What about my thing, any input on that?
light coyote
@radiant haven if you use the pause game node,
you can search for Is game paused
and it will work if that is the info you are looking for
the bolean in the set game paused node, is just to pause it, or unpause it
if set to true, it pauses it
if set to false, it unpauses it
For pausing it for a certain time
Easy way
custom event ,, pause node ,, delay node ,, pause node
autumn elbow
I find this very weird. Is there no way around NOT casting to set the physics to off on spawn ?
light coyote
custom event is not necesary,, but if you are planning on doing this in several scenarios,, is better to create a custom event, and just call it
grim ore
you can use a blueprint interface if you don't want to cast
light coyote
@grim ore what is bluprint interface ?
grim ore
Actors do not have anything required in them but a component so there is no way for the Spawn Actor node, which returns a generic actor, to know if it has a primitive component in it or not without casting.
technically this is a BP thing as you could do what you wanted in C++ and it would hard crash
light coyote
hmmmmmm
autumn elbow
ok lemme try Interface
grim ore
autumn elbow
hahaha i just think what i choose from the drop down in the Spawn Actor, and what I plug in as a class var.. should result in the same thing
grim ore
so lets walk thru that, when you select a class in the drop down the node now knows exactly what you want to spawn so it can use reflection to look thru that class and know what it is and what is part of it
when you use the variable how does it know which class you will be spawning?
forest dock
So I waited for a bit and that Import is still at 0%.
What do you guys reccomend for a safe maximum size on Cubemaps? 393MB is the size I'm currently trying.
autumn elbow
grim ore
if you notice the Spawn Actor from Class node changes when you select a drop down, it's no longer called Spawn Actor from Class
autumn elbow
This guy should tell it what class it should be spawning
grim ore
again how does it know EXACTLY which class is in there?
your weapons array could contain 40000030390402023908309283 classes
autumn elbow
hmm... from the get [0] ?
forest dock
Does he have that number in a notepad for every time he needs to copy and paste?
light coyote
@grim ore quick question
If i have only one actor, and i do a get all actors of class,,,, am i casting ?? i mean, if i do that, i can access components from the object without actualy using the casting node right ??
Or did i just make a knot in my brain ?
grim ore
the get[0] says to get the first item from the Weapons array which is always static and never changing?
or can you sometimes get the Cat Weapon or the Dog Weapon when you get[0] ?
autumn elbow
oh i see.. because its not static.. it doesnt know
grim ore
yep every time you execute those 3 nodes it checks at that exact moment which means your Spawn Actor from Class node can never know in advance what it is supposed to spawn until it spawns it
autumn elbow
I thought its suppose to check before it spawns it
like, just before it spawns, check the value coming into the class input
grim ore
it does at runtime so when the spawn actor from class node runs it figures out the class then, not before.
forest dock
Holy shit it imported
Ok so I figured out 393MB is fine if you give it half an hour
gg
grim ore
@light coyote no you would not be casting when you do that because the get actors of class should return back the exact class as the return type unless you use a variable input
autumn elbow
but, as you said, it doesn't, get[0] could be a class higher in the tree, so thats why its defaut is actor
now I get it
๐
grim ore
yep yep the issue is the fact that blueprints tries and help you out by casting automatically when you specify a specific class in the node
normally it would just be generic and you would cast but some nodes change like that to help you out
forest dock
I feel like my language must be flawed to be excluded as much as I am, while others receive thorough in-depth explanations.
grim ore
it depends on the question and who is here experienced enough to answer
like I am 3% experienced at art and art stuff so if it's art related I can't help ๐ฆ
bronze plinth
@upbeat tendon honestly I have yet to write a line of code, I really started working with UE4 this weekend and following a tutorial to get comfortable with the engine
I still feel its gonna be a mess to do both BPs and code at the same time but will see
I just wish I had more free time to dedicate to learning UE
autumn elbow
@grim ore Interface is the way to go LoL
bronze plinth
Btw i gotta ask can you develop games using real tracing lighting (not sure how it works honestly) ?
grim ore
you can using DXR yes and it will fallback to normal mode if the card doesnt support it. DXR stuff for the most part is post processing for settings.
like "hey use ray tracing for reflections" instead of screen space.
@autumn elbow yep if you want to generically talk to stuff interfaces are sooooo nice
they also work well as quick checks for doing stuff using the Implements Interface function, so like Line Trace -> hit Actor -> Implement Interface (cantakedamage) -> do whatever
autumn elbow
I love them now
๐
I mean, i use them all the time. Now more that I know the Spawn creates generic actors

Did Swarm agent get removed in 4.22 or renamed?
wary wave
no
grim ore
Mine is in C:\Games\Epic Games\UE_4.22\Engine\Binaries\DotNET
so yours is probably somewhere similar ๐

does anyone know any software that allows you to filter sounds easily? i mean something of a snapchat-filter simplicity where you load a sound, or a music, and can choose presets like under water, big hall, muffled etc and export it as a new audio file
grim ore
Audacity is a free audio editor that has quite a few presets and tools, reverb being one, plus tons of plugins for it. Might work? might not be one click simple tho ๐ฆ
plush yew
is there a way to turn off my whole actor moving to face the mouse direction? i tried using "orient rotation to movement" which does work except when im moving backwards, i want my character to strafe backwards but when orient rotation to movement is on he will never strafe backward, he just runs forward with the camera facing back
main cedar
its not there I dont have a DotNET folder
grim ore
are you using a source version or the launcher version?
@plush yew that would be due to the blendspace being used, it's just based on speed and it plays the run animation
plush yew
so i shouldnt use blendspace?
grim ore
you should but it needs to be a 2d blendspace to take into consideration direction and speed https://docs.unrealengine.com/en-US/Gameplay/HowTo/CharacterMovement/Blueprints/BlendSpace/index.html
plush yew
i am using a 2D blendspace
grim ore
are you using backwards run/walk for your backwards direction? for the animations
plush yew
yeah
grim ore
if you preview the blendspace then in the anim preview does it look right? like is he jogging backwards
plush yew
yes
my problem is just that he never strafes backward, he always turns backward because i have orient rotation to movement on
so if i move backwards, he turns to face backwards
plush yew
no my problem is
i dont want to use orient rotation to movement because it turns my whole actor to where the mouse is aiming, i just want his upper body to do that
when i use orient rotation to movement it pretty much just makes the aim offset useless except for the pitch
grim ore
ok so if you have orient rotation to movement off in the character movement component it should work?
grim ore
im confused and lost lol
plush yew
when it's on, it works as intended except when i move back wards
grim ore
when it's on the character is going to turn to face the camera, that's the way its set up
if you dont want that you would want it off
plush yew
hm
let me try to break it down cus maybe we got lost somewhere when i tried to explain haha
my goal: I want the upper body of my character to follow the aim of the player so he can face left and right by pivoting his torso to look natural
my problem 1: when "orient rotation to movement" is off, the WHOLE actor moves, imagine an action figure aiming forward and just spinning him around, thats what it looks like. I don't want that, because I want my upper body to move interdependently from the legs so it looks like his feet are planted and his torso is looking around.
my problem 2: when "orient rotation to movement" is on, the upper torso moves independently from the feet as intended, however there is a yaw limit of about -90 to 90, when I try to look behind the character, instead of turning around to face behind him, he just gets stuck on the yaw limit. I want him to be able to strafe backwards to face where he is aiming because as of right now, he can only run and gun in a 180 degree arc in front of him

How could I make smoke that reacts to collision?
cursive dirge
nvidia flow does this
but it's third party solution
also not super performant if you need it for bigger scene
spark sonnet
its for a multiplayer game
autumn elbow
@plush yew There are some setup for this on YT.. did you search there?
plush yew
yeah but following yt stuff would mean i'd have to rewrite my BP to match theirs
i think im on to something tho
yeah ok i figured it out finally
plush yew
my problem was for whatever reason i had a rotation rate of 360 in my character movement BP...lol
autumn elbow
you don't have to follow their setup, just see the idea
