why would you even use FColor
zenith flower
okay, so color is ranged 0-255, and mask is 0-1

Drag and drop a quad plane: low poly water
winter zenith
Sorry i'm new, what do you mean by "quad plane"
silver crown
Ah
upbeat trench
its like a bi plane but with more wings
winter zenith
😛
abstract relic
Polys are made of triangles. A quad is two triangles. The lowest poly square you can make
zenith flower
Are there good use cases for negative values with color/mask?
normal burrow
silver crown
u means unsigned
normal burrow
those planes
zenith flower
I didn't know it was 8bits
silver crown
Displays are 8 bits too
zenith flower
I'm speaking about textures/materials though
silver crown
Colors are Vector4
normal burrow
No
normal burrow
FLinearColor
upbeat trench
thats the sexy right there
normal burrow
I’m talking materials
silver crown
rhoo really 😢
silver crown
So you're saying colors in materials are not 4 floats?
normal burrow
float4?
normal burrow
Aye
manic pawn
doesn't it use halfs in materials 
zenith flower
that explains why anything * -1 is black in materials
upbeat trench
Protect ya Vect
zenith flower
manic pawn
vertex colors are FColor
silver crown
Well it's complicated
They're FColor on the CPU side
on the GPU they are 16 bits floats I believe
silver crown
True
normal burrow
What was the question?
silver crown
@winter zenith https://docs.unrealengine.com/en-US/Resources/ContentExamples/MaterialNodes/1_10/index.html can use this to animate your low poly water
winter zenith
Thank you!
silver crown
Was there a question
normal burrow
Find a plane in somewhere
abstract relic
Don’t they need polys for that phy? 😂
silver crown
Fun fact, I imported a plane once to use as a preview in the plugin
zenith flower
does it "roll" over?
silver crown
Turns out the uasset was bigger than the entire plugin
deleted the plane, used a proc mesh instead
manic pawn
material floats are signed of course
zenith flower
ah
zenith flower
Why can't color just be color regardless of context xD (I'm kidding I know why)
manic pawn
because 4x float is huge
normal burrow
silver crown
btw did you know FColor stores color as BGRA
manic pawn
do you actually understand how it works
zenith flower
Thats only like 1 page of 20
silver crown
😬
zenith flower
its a weather simulation that computes the temp, vapor, rain, clouds ect
upbeat trench
I have a strange suspicion Grid R is slow
zenith flower

Hi guys, im new

Hello
sudden geyser
Like literally my first day with UE4
normal burrow
Nice
upbeat trench
its my 92187th day with UE4... escape... leave while you still can 😮

MMORPG?
sudden geyser

Answer is always no
silver crown
Nice!
upbeat trench
racing hams sounds awesome
zenith flower
So to be honest, this is a paper someone release, what you are seeing my my translation of it to ue4/c++ so I can verify results vs the compute shader I'm working on.
I'm going to show you my "optimized" hlsl version
abstract relic
Good. Welcome to the asylum 😜
manic pawn
this looks like the usual math™️ code that some wizard wrote 50 years ago and since then people have been copy pasting and translating it without actually understanding
silver crown
heh
sudden geyser
Soo, the Vehicle variety pack... Can you use those vehicles to drive around in?
Oh, should I ask somewhere else btw?
I see the Sedan is a driveable vehicle but I wanna know if Im able to change it you know?
abstract relic
There are several free resources on the marketplace, epic launcher’s learn tab, a vehicle temple when you make a new project, and a care package if you read this channel’s pinned messages
sudden geyser
Oh, thanks
normal burrow
Yeah was gonna say we have a great pin finally
upbeat trench
Youre only allowed to change it to an RX-7 series 3 wide body not an FC 😛
silver crown
There's a free car example too right
sudden geyser
😂
zenith flower
Stuff thats computed more than twice per loop is saved like this:
silver crown
that's not in a compute shader right
zenith flower
no
upbeat trench
I didnt think you could do loops in a compute shader
silver crown
You sure can
normal burrow
They have to be unwindable mons
abstract relic
And why aren’t you using a dark theme? 😜
zenith flower
you can [loop]
sudden geyser
Alright, im going to bed guys
silver crown
that's how raytracing works for example
sudden geyser
Gn
upbeat trench
no wonder why raytracing is slow 🙂
zenith flower
I stopped working on this a year ago, hit a wall. I picked it back up 2 weeks ago, and re-did everything. So nothing is optimized in the current version
silver crown
It's not about optimization
zenith flower
This is the old c++ optimized version
silver crown
it's about code readability
upbeat trench
beeeejeeeebus
silver crown
zenith flower
dude, its 20 pages of this. You aint reading shit xD
silver crown
that's 3 times the same code
upbeat trench
What does it all mean
zenith flower
no its not
silver crown
You have one variable changing
zenith flower
more functions?
manic pawn
this would fail every code review at every company ever
zenith flower
Right now, i just need to make sure what I got from the paper, matches the output. So I change very little
zenith flower
Once its working and I have a valid test base to verify against I can optimize and cleanup
He did this in cuda, and only gave out the c++ version.
upbeat trench
so how do you know if its working if you cant even read it?
silver crown
It compiles ™️
zenith flower
Do you really want to know?
zenith flower
I compare the data in grids by hand at certain places in code
silver crown
🤢
upbeat trench
well you cant unit test it now can you
manic pawn
the paper probably has at least 3 typos aswell because of course it does
silver crown
heh
zenith flower
I know in the original 3 loops are 0 value, so when this hits the breakpoint on my copy, it should be on the 4th loop, and have the correct value
upbeat trench
so wait, you did that math by hand to find the correct value?
manic pawn
how would you ever find a typo in here
silver crown
Using machine learning ofc
zenith flower
You don't
normal burrow
Updates on that quad plane @winter zenith ?
zenith flower
upbeat trench
remind me never to hire the writer of this paper
zenith flower
zenith flower
I believe their simulator was like nearly 90% accurate at realtime speeds using consumer hardware
He only gave up the c++ code, this will look like however I design it
upbeat trench
fixed grid size though right
abstract relic
By their claim or peer reviewed?
zenith flower
You can change it
upbeat trench
yeah this is similar to fluid dynamics
zenith flower
yup
I plan on taking this and going volumetric shaders
for rain/clouds/temperature
(I use volumetric temp in my game)
silver crown
Making the big next gen tech all by yourself I see
zenith flower
It even interacts with the "floor"
so water puts more vapor into the air,
white roofs reflect more light ect
upbeat trench
cloud computing is the future 😛
zenith flower
I've been working on my game for like 3 years
normal burrow
Can I have a cloud computer please
upbeat trench
So in this game you are cloud?
zenith flower
I abuse the shit out of animated skeletons and static meshes for "machines" that are animated, but have swappable "parts"
My skeleton system, is actually just bones, with a single vertice attached so unreal doesn't complain
normal burrow
What’s the game about
manic pawn
old man fights against cloud
normal burrow
Clouds of war
zenith flower
well, your environment has impact on your choice of machine/weapon.
In Antarctica? Load up on heavy weapons' and don't let go of the trigger
In the desert? Choose wisely, and shoot only when you need to
solar crown
Hello all, i require some help.
An option to write the passes/AOS into one single .exr file.
Inclusion of ID (red, blue, green) masks for objects and/or shaders for better selection in compositing.
zenith flower
Want more armor, that will slow you down. Maybe you put more in the front, than the back
normal burrow
The whole frame buffer @solar crown ?
zenith flower
What about the bombs dropping from above? okay, more armor on the top, less underneath.
But what about the smaller machines that can shoot you from underneath? ect ect ect
manic pawn
where does the fancy cloud simulation fit into this
solar crown
@normal burrow yes
normal burrow
Clouds can be wet, making shooting hard, rain etc
manic pawn
but usually weather won't change that much in the small environment you'll have for a match
zenith flower
its more than clouds.
Its rain/clouds/humidity/temperature/snow/ice
all of these things effect your machine
you don't build one race car and run it the same on every track, every location
normal burrow
I assume you collect humidity then relay this to some table of humidities?
Or are you simulating molecules?
abstract relic
And more importantly. Are you using Houdini
zenith flower
Look, let me save you the trouble. What I am doing is over done. "unneeded" for your typical "match" ect
normal burrow
Gotta get that H
zenith flower
manic pawn
yeah just run Houdini at runtime
zenith flower
abstract relic
The plugin basically lets you
manic pawn
nah I mean when you use Houdini sim
zenith flower
oh
manic pawn
the plugin doesn't let you use it at runtime
manic pawn
houdini does not actually provide a license for that at all
zenith flower
manic pawn
that you could redistribute to players
winter zenith
Guys I have a question
abstract relic
Would be considered cruel and unusual
winter zenith
I've been working on low poly water through a BP
manic pawn
I'm seeing a lot of buttons that mean nothing to me in these screenshots
normal burrow
“My computer is on fire”
manic pawn
they're not buttons?
winter zenith
zenith flower
apart from the menu stuff, no
manic pawn
the things with F L T B etc
zenith flower
oh the armor?
okay yea, those are, but what you want me to do with them?
drag them on layer by layer? xD
manic pawn
idk, I have no idea what it means
manic pawn
oh.
normal burrow
But how do it affect things
winter zenith
How do you give a material transparency?
zenith flower
Say I shoot you at your back with a flamethrower, whatever I hit, gets hot. If too hot, that "module" inside of that body part shuts down
heat transfers though
normal burrow
Is there health?
zenith flower
within the sides of the body part, and also between body parts
yes
the 3d armor has 3d health
normal burrow
How many degrees is health?
zenith flower
and then the body parts have health its self
health != degrees
but yes, eventually I would want excessive heat to cause damage
normal burrow
Do they melt?
normal burrow
It’ll probably still end up being some feels good logic
manic pawn
what are those horizontal blur widgets
normal burrow
Just sounds incredibly difficult to put meaning to the temp
zenith flower
its all the "specs" of your machine
how much heat it can generate, how much weight, ect
abstract relic
Are you using Joule? Degree seems messy
And you’ll piss off someone which ever unit you use
normal burrow
If in doubt use radians
zenith flower
"Turn the other cheek" has use in my game
manic pawn
a heat of 3 radians
zenith flower
If you take to much damage from one side, you can reposition yourself
since you asked for it
abstract relic
Confuse the player further by using kilocalories
zenith flower
here is your joules, and conduction coefficients and surface area, and total mass, air velocity, enviroment temp
normal burrow
Or celcius
zenith flower
notice that air velocity and enviroment temp are not used?
yea, I built this with volumetric weather in mind
abstract relic
Celsius is used by most of the world pat
abstract relic
You uncultured swine 😜

manic pawn
what is a mesh data container float
normal burrow
I see no execs lol
upbeat trench
why not use macros
abstract relic
Nah, always explain it like it is a toddler. Said toddler is going to be you when you reopen that portion of the bp a century later.
manic pawn
does the bp debug even work
upbeat trench
you cant step expressions anyway
zenith flower
funny enough, I havn't opened this in a year, and understand it
normal burrow
Lol that old man toddler
zenith flower
I worked very hard to make it as clean as possible
manic pawn
last time I tried to view some values on pins it just refused to show them
polar hawk
if you disabled midpoint arrows this will look like 800% cleaner
zenith flower
bp debug works fine for me
some issue here and there
but nothing like macros
screw them
manic pawn
never tried to debug a bp macro lol
zenith flower
I love my arrows
upbeat trench
how bout not creating bugs
abstract relic
normal burrow
polar hawk
yeah most of the time I don't use the debugger
I just write code right the first time
thats how I explain to all my clients and employers my lack of debugging experience
zenith flower
Basically I'm setting up my mechanics to work somewhat like you'd expect in the real world.
normal burrow
Pudding of proof
upbeat trench
and Answerhub is back
zenith flower
Like whats this 1D armor bullshit. You shoot a guy with armor 9 times in the front, and shoot once in the back and suddenly he's dead like he didn't have 10 points of armor in the back?
polar hawk
my twitch streams are about doing everything correct 100% of the time while knowing 100% of the domain I'm in
normal burrow
Proof of pudding rather
zenith flower
I hate that
upbeat trench
It comes down to messaging to the player, its not always easy to message that someone has 10 points of back armour
zenith flower
it becomes apparent when you design your vehicle
you have to think about where you put your armor in a 3D way
I plan on having planes, tanks, human ect
upbeat trench
If you have visible damage but then that has to be accurate over the network
zenith flower
each one can hit you from a different angle, side ect
polar hawk
there was a mod for HL2 that had a commander on each team playing RTS mode while everyone else were the ground units and the ground untis could enter a tank factory and build their own tank but they have to customize their tank armor in a ton of different ways including where to place the plates and my god it increased game complexity buy a metric fuckton
zenith flower
true. I'm overreaching
but honestly when this is ready, we are looking at another 3-5 years

Source forts

polar hawk
full stack regenerative armor on the front, bum rush, get taken out by a single anti-tank rpg hiding in the rear
but can withstand literal nuke warhead impacts from the front

that game gave no fucks
upbeat trench

if a match went on long enough both teams just unlock nuclear arms

not if you have armor that can recharge using nuclear blast energy

Can you get element index from an foliage instant static mesh with a sphere collision overlap? I know how to do it with multisphereTrace, but idk about sphere overlaps. Is it possible?
polar hawk
then you'd have to use bio weapons
zenith flower
boom
normal burrow
Do you get a hit result?
polar hawk
and then the match becomes 'nuke armor, die over time from disease' or 'bio armor, get blown the fuck up'
upbeat trench
on overlap is the same hit result struct I thought
rancid lynx
I get ome result from the collision, but it said -1. Is -1 false?
normal burrow
It means none
zenith flower
I can't find this source forts, that shows the tanks with armor
zenith flower
oh
normal burrow
It’s something different yeah
zenith flower
damn
rancid lynx
The overlap triggers at the right time. Hmm.
polar hawk
is source forts just the box building one
where you got to hold on to the energy ball
because that shit was fun af lmao
polar hawk
yeeeeah and you can freeze boxes and shit
polar hawk
the meta became eventually to make sky forts
which at first seem impossible but fall apart with enough damage
normal burrow
Yeah fun game
polar hawk
then there was that same mechanic
but bridge building
which was too intense for me lmao
whatever gamemode that was
normal burrow
Do miss mods in general

the only game balance was balance for fun

The humvee is flickering with the smoke....like some rendering issue....

Someone know why my Damping at my PhysicsHandly doesnt work
polar hawk
@scarlet kiln im not exactly sure if this is possible or how to do it
but I'd look into disabling occlusion within your particle
or making it have zero bounds
or something
if it indeed is the particle
if you disable the particle and it stops it from flickering that is
if you disable the particle and it doesn't stop the flickering, well, its obviously not the particle
sudden agate
I would mask the the opacity with a box that's the size of the vehicle
scarlet kiln
I tried turning off the smoke and it still flickered...it seems like maybe some clipping might go on with the proximity of the vehicles?
But then I look in my editor and the vehicles aren't touching...

its not flickering. it's just that the particles fly through the geometry

@unique kraken that wont help your cause, also speaking about useless, looking at the logs, you have been helped quite often, and barely if not ever helped someone else.

enough google results though
fierce tulip

well first of all, a simple awnser to my question would be helpfull
if you are willing to help we can build up on that

I know jack about anisotropy in ue4, but I do know the hair-blend mode contains info about it, and that people think its still far from perfect
unique kraken
there we go, isnt that helpfull

unique kraken
bcs i think its pretty broken as well
what im basically trying to do
some sort of manipulating the specular
at least i know now its not enterly my fault not getting the hair shader to work
fierce tulip
I do remember a plugin that added anisotropy blending mode that looked amazing, somewhere on the polycount forums, but cant find it

If you pack your game and you have unused assets in your contents folder (no references) will it affect my game if is like... an asset I might not want to use

i saw that anisotrophic blend mode in some vid. wondered where it comes from.
question with this stuff is if its stable and what not
serene birch
I wish we could get direct anisotropy support in UE4, if needed only on the Forward Shading mode
fierce tulip
https://forums.unrealengine.com/development-discussion/rendering/19649-anisotropy-material comes with a download somewhere.

I just love the look of anisotropic materials 🙂

If anyone has experience with this or a good tutorial it would be really appreciated! Thank you

@light lintel didnt you get a reply from matthew last night about it?
hollow tusk
Can someone help me with this issue?
Been following this tutorial, but for some reason i messed up I assume
plush yew
@light lintel you can assign different modes, such as mode_gui different than mode_combat. And when you listen to a mouseclick, you route the action based on mode that you are currently in. while in inventory mode, mouseclick for combat are being discarded. Makes sense?
ideally you would use an enum
because you can have different modes, more than 2
such as, explore, combat, conversation, inventory, dead etc...
fierce tulip
both of you having the same avatar makes it so confusing for someone who barely reads names :p

alrighty I'll ask there ty

carmine garnet
i deleted a material instance and now ue4 crashes on launch
fierce tulip
always clean up redirectors
your saved folder should have a backup, but you'd have to rename it and place it in the right folder
grim ore
restore the material instance from source control and then do what they said
carmine garnet
what is source control
normal burrow
carmine garnet
i cant launch ue4
fierce tulip
source control is a backup system everyone learns about after they delete something they shouldnt have for the first time
grim ore
source control is when your team is trying to win by holding all of the sources to get a trifecta
fading vector
Could I get some help with this issue
I am trying to change the material through a button system
of my player
Let me show you what I have so far
normal burrow
Crypto
fading vector
normal burrow
if you look at the mesh in the editor
spare sun
ok nvm apparently ssr being tied to taa is an old problem that never got fixed since 4.14 or so
normal burrow
you'll see the materials have name slots
polar hawk
source control is when you're trying to take control of all copies of the magazine The Source because you dropped a terrible rap song and don't want people to find out about it
fading vector
Can I not set the default material based on the user pressing a button?
normal burrow
any material that is on disk as a material is treated as constant
you'll have to make a dynamic material instance or material instance dynamic
and bind that in to said slot in constructor script
fading vector
Im not sure how to do that
jaunty sorrel
Hey guys, I'm messing around with the sequencer. Is it possible to "start" or "simulate the world" (and all the animation/interaction that occur) during a shot ?
fading vector
I think you're confused on what exactly im doing
I have a widget bp
You click a button
it casts to the ball player
changes a material variable
however it wont go over when the next level loads.
plush yew
hi were can i ask things about world composition ( topic ) unreal engine game lags when other level loads
grim ore
if the new level being loaded is a new level, not using streaming or something else, then any changes you made in the old level are now gone
you would have to store that change somewhere else then load in that change when the new level loads
normal burrow
yeah,
if your setting a color on a primitive or something trivial its making a dynamic material instance for you
opal hornet
does anyone know where I can best get input on a HUD/UI design? discords, subreddits, or perhaps a channel in here?
grim ore
the game instance is an object that exists from the time the game starts to the time it ends, it persists across level loads. You can use that
opal hornet
game instance is a class that exists when the game is running. only one instance of game instance runs at a time, so some people use it as a global storage
fading vector
Sounds exactly what I need just not sure how to access it
fading vector
BP
opal hornet
to create your own game_instance class to be used, just create it how you make any other BP
and then set it to be used in your project settings
under Maps&Modes
this is ideally what you want to do
fading vector
Ahh thank you
opal hornet
yw
fading vector
I see there is nothing like begin play or event tick
So how can I store the info?
oh wait
I see
glad karma
Is good to use 4.24 or better older version?
grim ore
you use whatever works for you, if just starting out the latest version should work.
For example you might want a certain plugin that only works with an older version
glad karma
That is problem when I'll be use some tutorial from YouTube to learn I don't know what will be best one
plush yew
how i can turn off this emitter?
Cuz its looping and i want to turn it off sometimes
delicate needle
Help! I could have swore there was a new feature that would allow you to generate a box UVW in the SM editor. I don't see it. Is it out yet? Hidden?
umbral trout
@glad karma Download all the projects from Epic under the Learn section, dissecting those are helpful and they have a lot of use cases from networked MP games, to platformers, etc...
glad karma
Okay, so the best way is download 4.24?
grim ore
@plush yew save the return value to a variable then turn it off (deactivate) it when you dont want it on
@glad karma IF you are just starting go to learn.unrealengine.com and download the latest version on the launcher (4.24.3)
glad karma
Okay super, thanks! I'll be use some of video tutorial and documentations
opal hornet
does anyone know where I can best get input on a HUD/UI design? discords, subreddits, or perhaps a channel in here?

@delicate needle if you mean this then turn on the "Polygon Editing" plugin

@grim ore AH! I didn't lose my mind!
grim ore
delicate needle
It was on before due to datasmith/unreal studio.
grim ore
yep
opal hornet
yeah thats why i wasnt sure, guess ill try graphics in here for now. i couldnt find an active sub for UI/UX design questions
grim ore
nope if it's related to how the systems work #umg would be it, otherwise its more design stuff which doesnt fit in most places here
grim ore
nope

So when my actor is destroyed
my camera is destroyed too, however I'm playing death effects I'd like the player to see
Can I set whatever camera the game defaults to look at my actors last location?
opal hornet
yes
delicate needle
@grim ore - Thanks again. This UVW box tool just made my archviz life so soo much easier.
grim ore
yay
fading vector
Any idea how I can do that?
grim ore
@fading vector spawn a new camera, set view target with blend to the new camera, destroy actor
or uh dont destroy actor just ragdoll it or something while you play the death stuff then destroy it
delicate needle
I have another question for the room. Suppose have a lightmass build file, next to my map, but I want to re-load it and recompile it back into my map. How do I go about that?
fading vector
This is the scope of my game
Similar mobile games on the market that are too simple
I want to re-create this with more twists
them*
grim ore
there is something called a player camera manager that in theory is what you are currently using as the camera. I dont know if it keeps track of the spectator camera when you destroy the player. might be something to try. destroy actor -> get player camera manager -> get camera -> point camera at whatever ?
opal hornet
can timelines take in a starting value input at runtime?
somber condor
Hey! I have a weird problem today with 4.24.3... When I build lights in a level and save the level. then open another level and come back to the first one Unreal doesn't load the built lights anymore. whats wrong ? like it's not properly saving built data
fading vector
@grim ore Maybe the spectator class?
grim ore
if I was doing what you wanted I would do what I suggested. Spawn a new camera, move it wherever, rotate it wherever then use the set view target with blend node to make that the new player camera that we are looking thru. Then you can do whatever you wanted with your actor in the scene
white canyon
could someone please help me set up these 2 plugins?
Gameplay abilities plugin
Va Fog of war
opal lark
how do i check if player character has an object on there person what can trigger an event on overlap
So the ovelap knows the player has a certian object. if that makes sense
opal hornet
@white canyon set up as in enable them or getting started on using them?
formal pebble
Hey guys, Which value should I set in spawn actor rotate to make this two half coco nuts one rotating for right and the other for left according to my forward vector?
opal hornet
@opal lark is that object stored somewhere?
opal hornet
where in the code are you storing the fact the player collected it?
fading vector
Any suggestions on creating a fade out and fade in effect for death and restarting a level?
opal hornet
if its in the same level, then just use the level bp and check if its been collected. if using it for different levels, then store it somewhere outside level bp thats persistent, like gameinstance
opal lark
so i cast to character then check if she has it
opal hornet
@fading vector im actually working on that right now, you can do it programmatically but if you want it to be a rendered fade, i think you need to use instanced material(s)
opal lark
how do i checjk sorry
fading vector
@opal hornet So like increasing/decreasing transparency of a material?
opal hornet
@opal lark u can just use gameinstance to hold these variables. then cast to your gameinstance and get the variable, then do your logic depending on that
white canyon
@opal hornet dm's you
opal hornet
@fading vector basically
this is a basic example https://www.youtube.com/watch?v=aEZeGknl-HU
then you can get fancy like this https://www.youtube.com/watch?v=ZAstCGcImF8
jaunty sorrel
How can I unfreeze the sequencer view on the right ? (Everything is static)
fading vector
I dont exactly need an object to fade out but the whole screen
Fade to black more or less
grim ore
There might be camera fade nodes built into the engine using the Player Camera Manager class
smoky sonnet
anyone know how i can run my gif slower
i changed the time value to anything nothing changes
opal hornet
@fading vector if you cant find that node, its super simple to do from a viewport widget
grim ore
correct "Target is Player Camera Manager" which means you need to get the Player Camera Manager and call it on that.
grim ore
@smoky sonnet have you tried multiplying your time input by a smaller number? say Time * 0.5 then plug that into there?
smoky sonnet
@grim ore do you know how can i capture a object to my 3d widget but without loosing his real color?
now it looks cyan not shiny green
opal lark
This is all done in level bp. this detects the player has no item and it works. problem is how do i set the item to my chracter when she picks it up
grim ore
the player has an event when it overlaps with the coin and sets the variable on it or the coin has an event for when the player overlaps it and sets the coin variable on the player. The level blueprint should never be used.
opal lark
i see so its a bad idea to use level bp
regal mulch
The level blueprint should never be used.
Let's say, the LevelBlueprint should only be used if it's purely about the level itself.
It's not easy to access it (if at all). There are more options via C++ etc., but for BP users I would only use it for debugging stuff.
grim ore
if you never learn to use it, you can't use it wrong 😛
regal mulch
An example of what you could use it for, if you do have C++ access: We had a game where you could hover with normal gravity, but also with custom gravity that allowed driving on walls and ceiling etc.
That was specific to the map, so we had a boolean in the LevelBlueprint (or rather in the C++ parent) that we could query to adjust movement.
grim ore
and "how do I get a variable from the level blueprint" might end up going away as a daily question heh
opal lark
So what would you the say rthe best way to this them Matt mate. player overlaps coin or vice versa
regal mulch
Player overlapping the Coin should be handled inside of the Coin BP itself.
grim ore
either one works fine, if the coin is an independent item i would put the overlap event in the coin and check for the player ^^^
opal lark
Ok thank so this be i sent to you looks ok
grim ore
no reason for the players overlap events to check for coins and bullets and parrots and doors and ...
@regal mulch in that example, the boolean in the level blueprint, how did you get it out of the level blueprint?
regal mulch
Only BPs are lacking the function to get the LevelBP
grim ore
ah gotcha
regal mulch
The Boolean in your image, who is that belonging too, logically?
Is that part of the state of the player?
Or of the coin?
opal lark
self
regal mulch
No, not coding wise, just logically. Who's state are you describing with that boolean?
E.g. "IsDead" as a boolean, that would usually describe the Player being dead (and not the coin).
So what is that boolean in your image for?
I'm asking cause it looks like you are setting this boolean in the coin, while it should be in the player.
opal lark
yes i want the coin to be set
regal mulch
So you want to save that this coin has been picked up by the player?
opal lark
yes
regal mulch
Do you want to be able to get this information from the player later?
regal mulch
Is this boolean right now in the player? :D
Cause your image suggests it's in the coin
opal lark
im in the coin bp but ive cast it to character
regal mulch
Yeah but the cast doesn't magically make that boolean the one of the player
You are chaging the boolean that sits in the coin
Do you have that boolean in your MixamoPlayer Blueprint?
opal lark
what will i need to do
regal mulch
@grim ore
if (ULevel* CurrentLevel = GetWorld()->GetCurrentLevel())
{
if (AHLLevelScriptActor* HLLevelScript = Cast<AHLLevelScriptActor>(CurrentLevel->GetLevelScriptActor()))
{
bDynamicGravity = HLLevelScript->UsesDynamicGravity();
}
}
@opal lark Answer the question: "Do you have that boolean in your MixamoPlayer Blueprint?"
opal lark
yes
regal mulch
Then click on the "As BP Mixamo Player" pin of the cast node, drag it out and search for the variable.
opal lark
i have so it shouls work
fading vector
does beginplay start with every level load?
regal mulch
@fading vector Depends on the Actor and the Travel Type. E.g. SeamlessTravel doesn't make PlayerController BeginPlay call if it persisted iirc
grim ore
@regal mulch yep yep I gotcha. I always forget they keep not exposing stuff like that to BP 😦
opal hornet
is there a reason they refrain from exposing everything to BP by default? how much of a performance hit is it to just be exposed?
grim ore
in the end I don't think there is, they just might need to do more work making sure its safe I guess or a good reason
grim ore
i mean it's work for someone and if they don't need it....
opal hornet
id imagine that work could be automated
opal lark
i used to level br. now i know that the wrong way how do get the coin to know if player has overlapped it ?
fading vector
Awesome, my game has come a long way. Hopefully sometime this week I can show everyone a preview of what I've been working on 😄
opal lark
i figured it
kindred viper
Rather than exposing C++ to blueprints, they should have simply had an interface applicable to a construction node. So you add the interface and the node builds based on the meta data of the C++ class. But I guess there is a reason im not on the engine team, and its probably because my ideas are a bit whacky at times :p

Anyone know why an emitter won't render through a transparent widget? 🤔

How i can shake the camera?
i wanna try to add some action when i attack
is that possible to do a little shake?

@winged crypt 3d widget?
@plush yew small disclaimer, if you're making networking/multiplayer game, you may add player camera shake, not world one
winged crypt
@next badger Yeah
zenith flower
are c++ floats = bp floats in terms of precision?
next badger
@zenith flower um...nope =))))
ue4 does a lot of weird stuff behind the scenes
you can flip ints when converting floats etc
zenith flower
Why can't they just make normal floats and offer "reduced" floats
its screwing with my weather simulation.
next badger
afaik all the MATH class is affected
zenith flower
so FMath:Min or FMath:Max is trash too?
next badger
@zenith flower i think your answer is in the ue4 source...it's not that hard to find
zenith flower
I'll pass I remember hearing about this before. Everything I've done is unreliable now. I have to download a stupid plugin to fix this
next badger
@plush yew is that just an effect or a part of the game?
@winged crypt are you using custom depth?
plush yew
Am making it a bow
😄
Ganna add animations to it
Just wanna know dose it look bad or is it a bad idea 😄
next badger
@plush yew if it's a part of game you should test in in the context of a game...in level etc
next badger
for me the rigid movement of the bow itself is more issue than a trail
plush yew
cuz its getting into the player while movin g?
next badger
no, just in general, it's disturbing the flow of movement
cause it's large compared to player

how do you update engine version? I think I used to have that option in the launcher in the same place where I start it but it's not there anymore, I have 4.22.3 at the moment.
zenith flower
4.22.3 is the max for that version
if you mean going to 4.24
or 4.23
click that yellow button in the library tab
fringe pivot
But I upgraded this many times, 4.18 was the last fresh install IIRC
zenith flower
you don't upgrade between version, you install new ones
you can upgrade sub versions
like 4.22.1 to 4.22.2
but you install new versions like 4.22 to 4.23
fringe pivot
weird, I'm almost sure I did it
opal lark
Can some please tell me why this is not working
zenith flower
You don't upgrade between major engine versions. You can upgrade projects, to newer engine versions
you can't upgrade the engine itself to a newer major version
@opal lark which part is not working
You have to be more descriptive
opal lark
the whole thing
fringe pivot
Anyway, can you import megascan freebies to the new quixel mixer software? I think it's called bridge now.
zenith flower
no such thing, if you're overlap doesnt work nothing else will. If your overlap works but your boolean is broken, nothing after taht will. ect ect
Just because you don't see the end result does not mean the whole thing is broken
put some breakpoints in there
start from the beginning and set a break point and step through it
If your breakpoint on the Actor overlap doesn't hit, then you have an issue with overlapping
mossy nymph
aside from that boolean on Player being set to false
the same thing happens on overlap
Player or not, the light goes invisible
zenith flower
or the issue with using the cast fails to turn off the light
mossy nymph
failed or not, SetVisibility(false) is called
zenith flower
its still an additional issue, once he fixes the boolean
he shouldn't use cast failed most likely
zenith flower
I still don't see any breakpoints. We will not armchair debug this for you.
opal lark
break points you mean strings ?
opal lark
ok
zenith flower
a red circle will appear
then press play
when walk up to your actor you want to overlap
and you SHOULD hit the break point.
opal lark
ok that parts works
zenith flower
kay, now "step" through your stuff
opal lark
i mean is the bool set up rite to recieve
zenith flower
dude, there is a process, stop jumping ahead
ect
follow that, and it will show you where it "breaks" then come back and you can ask us a more precise question
You need to learn how to debug your code, or people will only start ignoring your questions. Just helping you help yourself in the long run
opal lark
Ok thanks for the advice

use the select node, feed in a random int in range, and output the camera shake on 1 of them with nothing on the other... (not serious)
