The other problem is that UE4s default behavior is to override child variables if the parent changes them and they were the same before.
#ue4-general
regal mulch
So if the array gets overridden via the child to parent bug.
And you clear the array on the parent
it also clears it on the child
gg
The issue with this is if you have variables, like booleans, that have very likely a default state shared with the parent
One child sets the parent to something you don't want
You change the parent
And all other children that you maybe want to have on that value, reset.
tawdry storm
oof yeah no idea how to theck that on the fly, but so far if I compile the parent after the child it seems to behave normally, but yeah this shouldn't happen at all
regal mulch
Parent bool false
Child 1 bool true
Child 2 bool false
Child 3 bool false
Change Child 3 to true ->
Parent bool true // Changes cause of the bug
Child 1 bool true
Child 2 bool false
Child 3 bool true
Fix Parent back to false
Parent bool false
Child 1 bool false // Changes cause BP default behavior
Child 2 bool false
Child 3 bool false // Changes cause BP default behavior
gg
tawdry storm
lemme try 1 sec
yup
so if I change a bool somewhere inbetween I have to go from the lowest child all the way up to see the expected result, but yeah once I change the parent everything goes tits up
I guess the binary state of bools makes UE4's behavior in this matter really finicky
jesus with 4 children it's so weird how every compile seems to have sweeping changes throughout the hierarchy
I'm surprised this hasn't caused anyone problems before 🤔
next badger
@regal mulch i've reported similar bug some time ago...can't recall if it was accepted or not...
the problem was that if you change the property on parent to the same as child had, it will reset the custom property later
Parent - A
Child - B (custom)
Parent - B
Child - B (not custom)
Parent - A
Child - A (as it's not custom anymore)
tawdry storm
I think they're similar, but not the same, but the initial problem he described probably causes the later problems that are the issue you describe
regal mulch
Yeah that's not a bug
It's a shitty design decision
Basically BP Children don't know their state is changed
BP Parents update the children based on the properties being the same
next badger
yeap, but if i've set the property on child manually, why would it reset it later?
regal mulch
Because the Child doesn't know that
In C++ this can't happen of course
But in BPs the child or rather the parent, doesn't know about that
If the default value of a boolean is false (0) in general.
And the child has it true, then as soon as the parent has it true, it counts as unchanged
next badger
can't BP just store the value no matter what? (if the property still has same type at least)
regal mulch
I think the issue is that Epic didn't add a way to keep track of that
In C++ the child would actively write "bSomeBoolean = true" in the constructor
And the parent changing back and forth doesn't change that line
But BPs don't do that. They only have != or == parent
Same should happen with more complex variables, like a string
Parent ""
Child "Hello"
-- Change parent to "Hello"
Parent "Hello"
Child "Hello"
-- "Change parent to "World"
Parent "World"
Child "World"
Compiling in between though
next badger
I thought that setting some value in BP child acts like adding a constructor custom value

I've always used steam for testing multiplayer and now I'm trying to do it with the default sub system. I'm using AdvancedSessions and would like to open two instances from the editor at the games main menu and have one listen and then the other join. Do I need to do anything extra to find the session ? Should I specify the loopback address somewhere to join it?
The session's there but I can't get the other instance to find it. I'm not sure if I'm forgetting something or not. I'm working through the docs to try and find what I'm missing here but if someone can help save me time figuring it out I'd be grateful.
regal mulch
Inside the editor or at least standalone?
scarlet birch
I'm fine with either. Should I just build it? Can I run two instances with Standalone? If so I may have tried it wrong.
Ultimately I just want to test basic stuff on one machine before using 2.
ok, yeah standalone is running 2 now. But not finding the session on the other instance
rough hound
How would i create a "timer" that plays a sound at a random time, and when it plays a sound it has a cooldown before it can play a new one? This is what i have so far.
Should i make a new function that deals with the stuff and then use delay instead maybe?
cause delay won't work like i have it now.
grim ore
set timer by function name -> set random time on the timer -> timer points to the custom event to play the sound. After the custom event sound is played -> set timer by function name -> set random time on the timer -> timer points to the custom event to play the sound.
sly coyote
So tricky on event tick...that's every frame...
No matter what you put as conditions they'll be met like 100s of times a min
Giving very bad results
rough hound
I could probably do something else? I'm very new to UE4. I'm used to having "think" functions which are way less frequent than ticks.
sly coyote
Can you set up a collision sphere instead and do what Matthew suggest
Have it only happen while in the sphere...cause yeah on tick would be not so good and completely unpredictable...you want random, not crazy
wise marsh
No matter what you put as conditions they'll be met like 100s of times a min
@sly coyote event tick 1.0 its 1 sec so its 1 per 60 frames
sly coyote
I have a GTX 2080 ti...on a 240mghz monitor...my tick triggers 240 times
Per sec...on tick is called at every frame refresh
rough hound
I'm trying to make this man make some idle sounds, to give some more context
weak cypress
does a bigger+better monitor help with game development?
sly coyote
That's why you never tie important functions to tick because the results will be unexpected
rough hound
You get more efficient with 2 monitors at least.
sly coyote
You can set it up in ai behavior tree
scarlet birch
I'm just going to work through it from start to finish. I must have forgotten something simple. It's always just worked before.
rough hound
I can play sounds through behaviour trees?
vast pine
Anyone familiar with the ins and outs if you wanted to make release project files on github as GPL?
sly coyote
You can do tons of stuff with behavior trees, it has a steep learning curve and not enough tutorials tho
rough hound
hmm
so i make a new task for the behaviour tree i guess? PlaySound won't work for what i want.
sly coyote
You can also add notifies In multiple idle animations
wise marsh
You can play sound until your bool idle its true but with a delay with a random in range float
@weak cypress
sly coyote
And have the idles be randomly selected in anim bp
sly coyote
And on notify have it play...
But now that I think of it, sound que allows for random sounds and you can add random delays In the sound cue itself
sly coyote
There's a lot of way to handle what you're trying to do...but not In Event tick
rough hound
I've figured out how to randomize the sounds in the sound cues
random tree
does any one know how to use c++ in unreal
rough hound
But i also want these sounds to be randomly played throughout every animation
not only the idle animations

@random tree once you learn C++ properly you can then learn the small things that UE4 has specific like their heavy use of Macros and using the docs https://docs.unrealengine.com/en-US/Programming/Introduction/index.html can help once you learn C++ normally

Creating a dynamic collision physic. Is this possible?
gleaming creek
@rough hound If you want something to happen after a delay, just start a timer once, e.g. on BeginPlay
You want to avoid using On Tick unless you have no other choice, as it's expensive
You usually only use it for visual things that need to change every frame
If you're playing a sound, you can hook up an event to fire when that sound completes
which you can then use to start the timer again
Though for an even simpler solution you could just make it so that the timer just repeats at x interval, meaning that longer lines would have slightly less time between them
Which would probably be fine too unless there's huge variance between the length of your idle lines
You could also check if a sound is still playing and not play another one if it is

digital anchor
character has code simulating a biped person, with some custom movement code like crouching, swimming etc, and has some code for networking, prediction and simulation etc

@here Hey, I'm working on a stealth game with a cctv camera/monitor system. I modeled some of the basic assets in blender and just had a quick question. I want to create a multi-monitor wall mounting system for a cctv room, and I'm trying to decide how to go about it. I thought of creating an armature for it and importing the model as a skeletal mesh, but then I wasn't sure how to edit the bone rotation in real-time on instances. I then thought about using a spline component, but I don't know how to make a non-bending spline (I don't want to bend the mesh, just the joints). Also, I'd want tomake a bidirectional spline, where two branches come from one central socket/joint. I don't think that's possible, though. Any advice?
worn granite
Trying to get a handle on UE4 might take a bit, @frank oar. You'll get a feel for it. Most things have an event graph, if it's a kind of blueprint

When you say 'oculus touch', (don't laugh at me), I assume it's a button rather than a touch screen. Is it not?

yes, its a controller with buttons and stick like any other so i would assume its the same as any other controller input..

Huh, I'll get out of you're way and let someone more experienced help, but I've never seen that event before. It looks like it should inherit from UMG rather than something you could use as an input...
Wait, so when you type "Input Play animation Right (B button)" in you character's event graph, nothing comes up?
That's the event you should be using if you want the animation to play on that button press

Does anyone know if it's possible to set only a section of a landscape to use tesselation? Even though there's only a small section getting tesselated close to camera I'm suspecting all vertices of the entire landscape gets a distance calculation to check if it should tesselate. It's really slow when switching it on, despite only a small area gets tesselated higher than the rest.
silk lintel
idk i dont run discord servers...
@celest creek dont think so
@plush yew you also have to use wp offset + tesselation multiplier
celest creek
Does that make sense though - that it'll get a lot slower despite only a small section will get tesselated further?
celest creek
My landscape is quite massive..
silk lintel
i mean you could use level streaming to create multiple terrains, only one with tesselation
landscape layers are still pretty buggy
normal burrow
rumble monk yeah tesselation works this way, doesn't tesselate far away things
silk lintel
once they get out of beta might be an option
celest creek
It's actually a lot slower just by setting the material to tesselate, while setting your values so that nothing actually does tesselate..
silk lintel
@celest creek @normal burrow yeah im not sure what the problem is... 0 tessellation vs tessellation off shouldn't be that much of a performance difference
celest creek
@silk lintel Ok, maybe I can see if there's something I'm doing wrong if so then
silk lintel
do you have flat, no crack disabled, adaptive disabled?

That's my settings. And I'm checking it in wireframe and only close area gets changed when switching tesselation on/off, but frame rate drops hard

ill let someone with a bit more experience take over here, but there should be some sort of lod controls you need to adjust
wanton wadi
Quick question: is there a way to temporarily enable (rotation) snapping in the level editor? I'd like to hold ctrl for example when rotating so it snaps to the grid, instead of having to manually toggle the "snap" button
celest creek
But that hill is the same and it's perfectly fine FPS-wise without tesselation
silk lintel
@wanton wadi depends what you mean
theres 'snapping' as in 'snap to grid intervals', and theres 'snapping' as in 'snap to mesh'
celest creek
@silk lintel Ok, thanks for your feedback 🙂
wanton wadi
like -> rotate freely -> hold control and it snaps -> let go and its free again
wanton wadi
in editor yeah
but instead of having to manually click is isn't there some hotkey to toggle / temporarily enable it?
wanton wadi
in most editors its like "shift" or "ctrl" that enables "snapping" to angles and such
celest creek
@plush yew I just added some stuff to the inputs that get exposed when you set the material to tesselate
wanton wadi
thanks Shogu, but then I suppose I need multiple keys? 😄 I can't jsut use "ctrl" apparantly

@surreal raft first of all, good for you. You made the right choice.

Guys, when creating an animated shader with displacement, where could you switch on again that the displacement doesn't split faces up in your model (at UV seams and so on)? I know there was just a box that needed to be ticked but I can't quite remember where

How slow is a cast vs a "doesImplementInterface" node?
rotund scroll
probably roughly the same, does implement might be the tiniest bit faster
considering the sets of available members
the running time is probably still O(log n) in either case so the improvement might not show up even
violet goblet

can i use a mask with that node somehow?

what is Post Process Volume?
violet goblet
i guess the area where post processing is done, outside of it, it has no effect (i am just guessing here)

okay

yep
you can make it global as well
generally if you're making it global though it might be a better choice to add it to the camera you're using, especially for single player

I hate the feeling of when UE4 freezes for a second and you've got unsaved work so that whole time while it's frozen you wonder if it's about to crash and lose everything
sage coral
Just a quick question is Ue4 capable of using things like IK and face controls?
indigo abyss
I have a components best practices question.
I have a component (let's call it BaseComponent) that is added onto my BaseCharacter. I have multiple characters derived from BaseCharacter. This is all working great.
I've reached a situation where I want to specialize and differentiate BaseComponent by creating versions of it (BaseComponent1, BaseComponent2, etc.) that are derived from base. These components fulfill the same purpose, but have different logic and behaviors in game.
It seems now like I need to remove my BaseComponent from BaseCharacter to do this, so I can put the correct derived component (BaseComponent1, BaseComponent2, etc.) on each character. I can do this but as a result I'll lose the "every basecharacter has a basecomponent" aspect of the component, which is nice. I find myself wanting to "override" the component so I can maintain that, but I don't think components work that way.
Is there an implementation pattern I'm missing her?
grim ore
@sage coral yes
sage coral
@grim ore ah ok thank you Im using makehuman as a base and the skeletion was going all weird I found that the IK seems to work much better and act more realisticly
plush yew
hey im new and i really need help
i was beginning my journey into the unreal engine first hour project but i messed up along the way how do u restart from scratch

nobody knows my thing ?

@blissful trail is this a blueprint question?
blissful trail
its a math question thingy
tidal totem
So they technically should both stop at 100? @blissful trail
blissful trail
one should stop at 100 the other should stop at 163 but at the same time
tidal totem
Then they both can't be going up by 1 every second
civic lance
^
blissful trail
i can alter the one that goes up by 100
tidal totem
the one at 163 needs to be going faster, or the one at 100 needs to go slower
tidal totem
that is the only way that they can meet at the same time @blissful trail
fleet cedar
@blissful trail When you say "every second" are you doing that in a timer event or a tick event?
tidal totem
You would have to have the var = 163 moving at approx. 0.61 while the var = 100 moves at normal speed
plush yew
How do this?
tidal totem
so about 1.61 seconds for every 1 second that passes
You either have 100 seconds or 163 seconds to work with. I decided to go with 100 seconds. To fit 163 seconds into 100 seconds you need to divide the two...100/163. You end up with approx .61, which would be .61 added onto a second. That would mean that for every second that passes for the var = 100, 1.61 seconds would need to pass for the other var so that they both would finish in 100 seconds
I'm nearly positive that I am doing the math correctly
fleet cedar
@plush yew There's a few ways to do it, one way is a bit more complicated than the other way but it's got the advantage of being easier to tweak
tidal totem
but that is if it is being based off of standard time
fleet cedar
@plush yew If you're using the character movement component, you can set the max walk speed like this:
So when you press your button to crouch, set that to the speed that you want to walk at crouched
tidal totem
@blissful trail
blissful trail
yes
fleet cedar
There's a different way to do it which is better for the long term, but try that out and if you're happy with it then go with it
plush yew
I set it up the old way i think
tidal totem
did that work for you? @blissful trail or is it still not working correctly?
fleet cedar
@plush yew Mind posting a screenshot of your setup?
plush yew
Hello
civic lance
so is there no way to add bumps/irregularities to the default plane mesh?
i know its obviously possible with landscape
fleet cedar
@plush yew So after you set the camera location, you also need to set the speed like I posted in the screenshot
And probably also resize the capsule for accurate collisions
plush yew
where do I attach the character movement node
grim ore
@civic lance no, the landscape system is different than the mesh system. You can use the new mesh editing system in .24 and later to try and add details with sculpting
fleet cedar
@plush yew How long have you been working with Unreal for?
plush yew
3 weeks
fleet cedar
You might want to do a few structured tutorials since they're pretty helpful for getting you up to speed on how to do things on your own
Making your own projects is a great way to learn but you also need to get a good foundation first
This is my go to recommendation as it helped me a lot: https://www.youtube.com/watch?v=GCCIBnwhzSM&list=PLwmGmCVti_dDV27SVvB56m-tgabXzOvou
Since it's a 2D tutorial you get to just focus on the important basic parts of programming

Testing out projectiles , how do i move this collision box ? i can scale it but not move its location its anchored to center... unless there is a ignore collision from spawn ?
it is set to delete off collision but the box is in middle @spark sonnet (if you would like to take a look)
fleet cedar
@timid carbon That's your scene root component that can't be moved there's a few different ways:
- Add a new scene component and call it root, child everything underneith it should work for your method
- Child the collision to the beam and make the beam the root
timid carbon
its moving everything
fleet cedar
Yeah so now you'd have to do in and move everything back to where it's supposed to be
ivory sail
just an update i figured out what was wrong my snap values were set waaaaay too high for some odd reason
Thanks for the help @next badger & @tidal totem
timid carbon
not sure if all that has to be above like it was before ? but now there is no collision 😦 it does not delete at all
fleet cedar
@timid carbon Show me where you're detecting the collision in the blueprint
timid carbon
as soon as the collision box hit something it deleted itself,,, but the collision box needs to be moved
fleet cedar
Oh I see
Well first of all, why not just have collision on the mesh and skip all of this?
Then just make the mesh the root component
fleet cedar
No problem

question, hwo many actors is too many actors?
winged notch
explain
half turtle
is 10000 static actors too many if they have point lights and a collision sphere? how can i make the engine not process actors that are too far away from the player pawn?
i am makign a game that creates kind of miniature galaxy with stars and planets, it spawns Max about a thousand stars with max 10 planets, this stars only have light sources, and some pseudo gravity bound by a collision sphere
the planets orbit the stars, but is not really important if they are a million kilometers away from the player
and id ont want the game calculating lights from this stars that are super far away
winged notch
I believe unreal engine 4 infinite no actor limit

winged notch
What
half turtle
because unreal has only fake gravity towards the z axis i made fake gravity with the collision spheres as mentioned, and this spheres are constnatly getting overlapping actors to see what to pull towards the star
when i have 2 thousand stars, that is 2 thousand 15000 radius spheres constantly checking for overlapping actors
and some spheres are even twice or triple that radius

Hey, does anyone know if Multiuser editing works with C++ code?
And/or if this is planned to be implemented?

do gravity applies force to whatever actor that receives that message
winged notch
I would recommend set is up to only spawn the gravity on collision event
UE4.22 Multi-User Editing doc
half turtle
i tried that before, using on begin overlap and end overlap to add the actors that had to be affected towards an array, but it glitched horribly, sometimes when ships left the collision sphere, they would become able to accelerate towards infinity in seconds
winged notch
Im still trying to get multi user editing myself
half turtle
and even now sometimes on hit and overlap seem to not execute at all (i have had ships crash against a star and bounce off, even tho teh stars have a destroy actor on hit)
winged notch
try spawning 2 shape 1 for spawning the overlap event and 1 for the gravity
spark niche
@winged notch I had a look at that, and I've got multi user set up with two users. But when I edited and compiled the C++ code it didnt update for them.
Moving models in the scene, and making "content" changes seems to be reflected. But I'm not sure what happens to C++ files
winged notch
Are you Hosting the multi user session

so what is the msot recomended approach for this : i have created my main menu, however the way i made my game, the game controller has the components that spawn things and essentially all the rules.
when the game starts, it starts wtih a blank level and the default base game mode controller.
when i press new game, it loads my game level, which has an override for my custom game controller.
should i use this approach, or should i use the same level i start in and just generate the world on it after i press play?
also if i cast to class, does this affect any instances of this class that get created afterwards?

On that note. https://i.gyazo.com/e03d42820be86d352ac1ee7c721a33ac.gif What would be the best way to create an sustained damage for this laser.
I'd assume using tick would be too intesive. (Like Apply damage every tick)
exotic cave
@rough hound : Tick is fine, but do it in a time independent way
rough hound
I was planning on starting and stopping it the same way i do the laser
exotic cave
Tick should have a real-world time-elapsed since last tick somewhere, I can probably go look it up
And then just use unit analysis to make sure you're getting DPS, not DPT
exotic cave
You didn't have this in math class?
You want damage per second, but you're in a loop that happens per tick, not per second
rough hound
I'm not from an english speaking country.
Yeah i get that. Wouldn't there be a problem with doing damage per tick, as tick is called every frame right?
rough hound
Say you have 60fps at one point. then 120fps next time. Wouldn't that double the amount of times the damage is applied?
During that second
exotic cave
Not
If
You multiply by your time delta 😄
Every tick, you actually get the time elapsed since last tick
So, let's say you are at 60 fps. Your time elapsed since last tick will be about 0.016667 seconds.
Let's say your damage per second is 100 ouchies per second.
You multiply that by the seconds elapsed (1/60) and you get 1.6667 ouchies.
rough hound
Oh
exotic cave
Now your engine speeds up, you're at 120fps. Time elapsed per tick will be about half of before.
rough hound
Yeah that makes sense.
exotic cave
0.0083333 etc seconds
You multiply that by your dps and get .83333 ouchies
There are slight drawbacks to this approach

Ok lmao i def messed up cause i crashed my engine lmao.

hey guys, what is the hotkey for that thingy where you can see your map in red/green shows which areas need to be optimized etc?
I dont know the name of it
exotic cave
@wicked kettle : F5
civic cobalt
@exotic cave holy crap
exotic cave
At least if you're talking about shader optimization
civic cobalt
thank you
wicked kettle
it doenst do anything
exotic cave
@civic cobalt : Happy to help 😄
wicked kettle
with f5

sweet thanks man

How would you get the delta time for the ticks?
exotic cave
You have to be running, you know that right @wicked kettle ?
wicked kettle
running?
exotic cave
@rough hound : This I think https://docs.unrealengine.com/en-US/BlueprintAPI/Utilities/Time/GetWorldDeltaSeconds/index.html
wicked kettle
and yes its shader complexity
exotic cave
@plush yew has the right key combo for in-editor
Then Alt-4 will turn it back to your lit render
wicked kettle
@exotic cave thank you so much
exotic cave
Thank @plush yew, I wanted so badly to be 3 for 3 here 😄
Instead I get two and a foul tip

@plush yew : You talking about how to write the script, or how to link it to the blueprints?
This thread seems relevant
I mean, seems fine 🙂
Assuming you don't mind the complexity of the actor component

Does anyone know how to solve the project not saving?
I'm getting this error for everything I change and try to save
The asset '/Game/ThirdPersonBP/Maps/1' (1.umap) failed to save.
Cancel: Stop saving all assets and return to the editor.
Retry: Attempt to save the asset again.
Continue: Skip saving this asset only.
and this is what it says in the console:

@dapper idol : Them's a lot of directory ditto marks, so to speak.
What is "Megaport +"?
dapper idol
thats just where my documents folder path is
exotic cave
Is that your Windows user name or user directory? O_o
worldly axle
@tawdry storm i guess its not even the arm length cause if it would it would not be 0 on the horizontal axis, but it does
exotic cave
Well, it can't delete your temporary map file.
grim ore
@plush yew the engine has Accelerometer support built in, you can use that to determine movemement. You will have to use math to determine what counts as a step or you can look at geting a plugin from the marketplace
dapper idol
It's a bigger hdd so I changed the path to this folder (a while ago)
tawdry storm
@worldly axle based on your video it looks to be centered to your capsule collision, so if it's parented to that it's location should be 0,0,0
exotic cave
I haven't used actor components really, @plush yew . I've only read the docs.
They seem fairly involved to me. If you don't mind that, by all means forge ahead.
plush yew
@grim ore Okay thanks
exotic cave
@dapper idol : Go in with Windows File Explorer or the file explorer of your choice.
See if you can make a backup of that map yourself, and then delete it yourself.
worldly axle
yup
exotic cave
One way or another, Unreal Engine is calling your filesystem and asking it to delete a file so it can overwrite it, and getting an access denied message from your Windows filesystem.
worldly axle
but i moved the arm up
so if the arm would be a length of 0
it would be still a bit up
no?
dapper idol
Imma try that @exotic cave
worldly axle
i mean i moved both the arm and the camera
exotic cave
That's not really on UE. It means there's something wrong with your current filesystem, which could be anything from your hard drive to system configuration to whatever.
rough hound
Hmm... What type of loop should i use for my laser? A while loop is giving me infinite loop error, and i'm not sure how i would set up a for loop to work with the timing.
exotic cave
@rough hound : Why do you need a loop?
Doesn't your animation have start/stop points?
exotic cave
I can't see your whole graph but I suspect you're misinterpreting what a While loop in a Blueprint does
That While loop will run inside the blueprint during that tick until it is false
exotic cave
Noooo
rough hound
lmao
exotic cave
You just want a single conditional
@plush yew : I think you're the only one today that I probably am not advanced enough to help 😄 I think if actor components make sense to you, go with them
rough hound
So i check the bool variable in my tick event and do the damage there instead i guess.
wary birch
Recompiling all shaders is slooooww
exotic cave
@rough hound : Yes, the "while" in your head is "while the laser is on", I think, but the while within a blueprint loop is something very different
wary birch
Wait, the skysphere is centered around the camera?
exotic cave
@plush yew : U da man 😄 I learned something new from you today (the Alt-8 in editor for shader complexity)
grim ore
@wary birch Define slow? 30 minutes or more or just annoying
exotic cave
@rough hound : I think you have the right idea 😄 Your conceptual "while" translates to "per tick", I think, not an actual in-blueprint while loop
"While laser is crisping actor, burn actor" is just a check per tick, not an actual while loop.
rough hound
Yeah
hasty pewter
https://ue.unrealengine.com/Quixel_RegistrationLandingPage.html - just gonna leave this here for anyone who's interested
wary birch
Around 20 minutes I think, it is more about the fact that the number is moving slowly
fleet cedar
What's a good channel for some vector math help?
exotic cave
In-blueprint while loop would be for doing a repeated calculation on something that you want to repeatedly check and happen all inside one tick.
rough hound
I should've known this because it works the same in the engine i used prior to UE4. Though i almost never used while loops. Always for loops.
grim ore
@wary birch what is your CPU on your machine?
exotic cave
@fleet cedar : What are you trying to do with them vectors?
amber tangle
Is there a way to reset the editor viewport? Somehow when I launched my editor this morning, it's somehow acting like there's incredibly weird culling going on (even with different maps)
Not happening in the play standalone
wary birch
i5-8500 @ 2.8GHz iirc, although I'm on linux so it should be a bit faster
exotic cave
Physics, raycasting for logic (line of sight etc.), or graphics?
grim ore
@wary birch ah yeah no hyperthreading so it's gonna be slow 😦
wary birch
Yep it is
grim ore
you are on linux so Incredibuild shouldnt be an issue, that was what I was checking for mainly
grim ore
part of visual studio on windows
exotic cave
feels happy to be among gurus today
amber tangle
it's wild - even PIE works fine, but the standard view only shows things at off angles
anything directly in front vanishes
not seeing any setting that looks different than yesterday
fleet cedar
@exotic cave In trying to describe my problem I think I may have found some sort of solution
grim ore
@amber tangle did you change your near clip plane?
amber tangle
Not intentionally, let me check
exotic cave
@fleet cedar: Often happens that way, still, would be nice to know your problem so that I can point you at the various channels around here
fleet cedar
But basically at the moment I'm trying to keep a vehicle AI on the nav mesh, so what I'm doing is calculating where it's position will be in the future and if that position is off the nav mesh then I want to apply either a 1 or a -1 to rotate back to the right direction
So gameplay programming vector math I guess
amber tangle
@grim ore it's set to 10, what should it be? (haven't intentionally changed it)
rough hound
Thanks @exotic cave Got it working. https://i.gyazo.com/1c61a06874345a3dbe217a2092e08c2b.gif
grim ore
nope that the correct #, was just a guess since that causes the camera to look wrong if its changed
amber tangle
Worth a shot
whatever it is, it's only impacting the main editor view, not PIE or standalone
grim ore
@amber tangle well you can try resetting the layout to defaults from the drop down menu, cant hurt
amber tangle
The show> use defaults? Tried that one
layouts > one pane seems to have done it
Wild
dapper idol
Thanks @exotic cave , making a backup and deleting the map worked, I can save again! :)
exotic cave
@dapper idol : No problem 😄
And just in time for me to head off and get some sleep after all-nighter. Be well all!
plush yew
found the issue with GetDllHandle when linking my DLL...my DLL was created for x32 but i put it in Binaries/Win64/ folder
amber tangle
(the weird part is it was already in one pane... so nothing changed that I could see... just suddenly all my objects appeared again. Wild)
grim ore
there most definitely are timers and delay
you literally type "set timer" and the options come up
rough hound
oh
south kernel
I am trying to get my phone preview to be in portrait mode but keeps going to horizontal
how can i fix that?
grim ore
have you tried to change the orientation settings in android for the project?
grim ore
do you mean on device or Play in editor on mobile?
south kernel
play in editor
grim ore
PIE has it's own settings
you can click on the common resolutions and choose a device, then the icon to the right of it toggles between portrait and landscape. If yteting mobile you should definitely make sure you use the mobile preview as well
south kernel
i see Thanks i couldnt find it for my life
grim ore
also play in standalone is different than Play in editor so that might not respect the play in editor settings
rough hound
So this doesn't work 😅 I'm trying to set a "cooldown" on my ranged attack. I'm guessing the delay doesn't run after finish execute.
rough hound
Yeah, i use those for other things but the problem is i don't want him to stop completely and wait for the cooldown to finish
i want him to go into melee range for example while it's on cooldown.
faint tide
I'm about to buy a new computer screen for my PC and thought it would be nice to have one that supports my work well in UE4.
Any recommendations?
I've noticed on some guides on youtube where people use really high resolution screens which seems to make their UE4 work much more overview-able.
midnight bolt
is there any tool to automatically assign 'correct', ie greenish lightmap res to my meshes?
rough hound
Which he does atm. But it won't re enable the ranged attack so if a target moves out of his melee range and the ranged attack is not on cd it won't fire.
rancid lynx
is there a node that executes pin 1 if X = 0, pin 2 if x = 1, pin 3 if x 2. etc etc ? a multigate that fires based on an INT or float ?
tough marsh
@rancid lynx switch on int?
rancid lynx
tyvm. ill check. very probably that yes
tough marsh
@rough hound im pretty sure after you call finish execute the rest of the code doesnt fire I may be wrong you be can toggle a breakpoint there and see
rancid lynx
switch leads me to believe the same. else they could call it sequence on int
correct. it only calls 1 path each time. tested and working perfect. ty ty
tough marsh
yeah it will only call the one int you feed into it and np
rough hound
the delay executes but is "deleted" right after.
or
the breakpoint works
But the delay doesn't go through
tough marsh
put the delay and bool before the finish execute also you said you were trying to do a cooldown epic already has a built in cooldown node for the bt
rough hound
?
How
Also if i set the delay before finish execute then it wouldn't be able to perform other actions while it's waiting for the cd to finish.
pallid thistle
hey guys, someone knows if ue4 have a global shake intensity multiplier?
to apply on game settings
tough marsh
then get rid of the delay and just do a set timer by event and set and unset the bool as needed
rough hound
Yeah that worked
or rather i just needed the cooldown part on the behaviour tree.
Here is my current version of him. It's still not anywhere near i want it but it kinda works. It doesn't like moving targets at all though lmao. https://streamable.com/6qsyf Think it's ok so far as my first AI though.
wintry forge
Ay boys. Do you suggest I learn coding from scratch (I have some very old experience w java and simple stuff like ahk, gamemaker) or just use the visual programming of unreal?
Also I'm restarting w unreal, what guide is the best to follow in your opinions?

I am trying to work with skeletal mesh lod generator, following this tutorial:
https://docs.unrealengine.com/en-US/Engine/Content/Types/SkeletalMeshes/SkeletalMeshReductionTool/UsingSkeletalMeshReductionTool/index.html
But my interface (4.22) does not match whats in the tutorial (also 4.22)
What could be the problem?
Number of lods box is missing
tough marsh
Check a different mesh it may be your LOD import
lavish glacier
there is no lod imported with this mesh, just default mesh
rancid lynx
@wintry forge i suggest you spend some time learning blueprints. they can do alot. alot. my entire game is blueprint. i know alot of basic java. i havnt needed any programming.
tough marsh
well check a different mesh and see if you have the same problem
lavish glacier
ok
wintry forge
@rancid lynx i made a partial game using blueprints in the past, but i was wondering if people saw a large advantage to actually coding everything. though just jumping in again i might as well get started with blueprints again 🙂 ty for the advice
rancid lynx
@wintry forge youtube search "wtf is overlap" mat wadstiens videos are amazing. https://www.youtube.com/results?search_query=wtf+is+overlap
thatll show you a quick examples of what blueprints can do. they are very fast. much faster than formatting program code
wintry forge
ill check him out 🙂 thanks man!
