grim ore
thats up to your project, 1uu is 1cm
and we dont know your map size or other parameters
hardy flume
yeah ofc ofc
cloud palm
@grim ore After I record it with level sequencer, do I need to insert it into the game with some bp?
grim ore
I also dont think your values should be multiplied by -1 if you are trying to find something around the AI that is calling that
@cloud palm you can add it to the level and just tell it to auto play on start for example, or load it up another way using the level sequencer player
hardy flume
it worked by the way thanks! but I am planning on the AI running away so I thought I'd get a random point opposite to that of where they are now
grim ore
well if your character is at say 1000,1000,0 then you would say hey -1000,-1000,0 find me a point and that point could just be back where you are heh
cloud palm
@grim ore so Is there a special node in blueprint named auto play on start or do I have to create a bp that will perform that?
grim ore
if you want it to run away it might be more math
@cloud palm nope auto play for a level sequence is a checkbox on the sequence if it's in the level
cloud palm
Oh ok
hardy flume
I wonder what the probability of that is @grim ore
but I shouldn't take chances should I
grim ore
not a large probability but this is where allllll the game design comes into play tweaking stuff lol
hardy flume
do you feel like its okay to put that into the Polishing part of the game tho?
cloud palm
@grim ore would I do the same if I want it to be at the beginning of the level? Is that a check box as well?
grim ore
if you want it to run away from the player there is stuff you could do like find the players location, and find the AI location, then do some math with vectors to get the angle away from the player for the AI then go a distance away in that direction THEN do the get navigable point with a small radius and it would run away to somewhere near there
@cloud palm if you have a level sequence in a level and you check the auto play button it will auto play it right when the level starts. If you want it delayed you would have to make a custom BP that would start it at a certain time.
hardy flume
gotchaa, I actually did have a question about the radius. Is it the radius for where the point is going to be, or the range of how far the AI will move?
grim ore
if the point is 0,0,0 and the radius is 100 then it will find a random point between 0,0,0 and 100,100,100
it's a circle outwards from that location
hardy flume
so in theory if the point is -1000, -1000 and then radius was 1 wouldn't it just be -1001, -1000?
-1001, -1001
or in between
grim ore
well it's a radius so my example wasnt correct either yours would be -999,-999 to -1001, -1001
cloud palm
@grim ore thank you so much, this really helps a lot
grim ore
there is the Draw Debug Sphere node you can hook up when you do that call and put in the same numbers and it will draw a debug sphere in that location so you can see what it is doing
hardy flume
okay well I set the radius to 1 and the ai stopped moving again xD
and yeah debugging is probably the best bet
grim ore
draw debug XXX nodes are sooo handy when trying to figure out math 😃
cloud palm
@grim ore If u can, I really hope that u can make a video on how to save and load for platform runner game
grim ore
yeah a radius of 1 will fail because your move to has a value for how far from the target before it's done and its probably way more than 1
hardy flume
makes sense
grim ore
@cloud palm I have covered the basic Save Game Object which is what is used for saving, beyond that it's just figure out what you need to save and putting that in the object and making sure it's updated when you save

Hey guys

steep ferry
I have a really really important question (at least for me its important)
grim ore
I do not know as I use it for educational use so no cost for me but 5% is correct and it can be different based on if you launch on the EGS and other factors
yep GDC 2015 is when it became sub free
hardy flume
gotchaa
cloud palm
@grim ore my game have around 50 game levels, if I want to save the information of how many level a certain user pass so when I load it next time it will skip that level, how can I do that?
grim ore
that can just be an integer of the last level beaten can it not?
cloud palm
Emm maybe
steep ferry
so well basically Im trying to make a random corridor generation and well let's say that I have 1 mesh for now and it can be looped so i did this blueprint
grim ore
unless you also need to store data about each level that has been beaten then it depends on how much of that data there is (high scores, times) then you can make a struct to hold that data and save it in an array or list for example (1 entry per level)
cloud palm
I was thinking of true and false variable lol
grim ore
a boolean array would work as well, one index for each level true or false
cloud palm
How can I create a strict?
steep ferry
And when I launch the game its like this. Its only adding and heres the question. How do I make the vector and rotation once add and once decrease every spawn ?
cloud palm
@grim ore do u have a video on that?
hardy flume
@grim ore looks like everything works, the problem you brought up is fixed so even if the monster went to a point near the player all the player would have to do is keep pointing their light at the monster to get them away. But thanks for your help!
grim ore
right click, blueprint, struct to make new structs
steep ferry
like 1 - adds 2-decrease 3-adds 4 - decreases (and loops)
cloud palm
Kk
grim ore
@steep ferry that sounds like using a modulus on the index would work
then based on the result from the modulus you can add or subtract in the loop
steep ferry
Well im using ue4 for 2.5 years and never used modulus. Probabl because never needed it
grim ore
it's the % in computer math
steep ferry
Oh
grim ore
which is not division because that would make sense lol
steep ferry
Yeah
so
What i exactly need to do again? (sorry i seriously never used it earlier and have no idea how it works)
steep ferry
Oh thanks
grim ore
basically you would get back a 0 or 1 based on the index being 1 or 2 or 3 or 4 and then you can do your math based on that for add or subtract using like a switch on int
steep ferry
Ok so
This guide is probably usefull but im too stupid. I guess im gonna watch it couple of times again
grim ore
as a generic example
but the %2 is basically giving you back a 0 or a 1 if the number is divisible by 2, you get back just the remainder of 0 or 1
grim ore
I guess an alternative might also be the flip flop node now that I think about it, it will flip back and forth between 2 executes every time you call it so you can put it after your loop
grim ore
might be... less nodes lol
grim ore
hell that works too, go if node
steep ferry
I mean
grim ore
programming; where the same result has 100 answers lol
steep ferry
in the demo of my scp game i made the corridors by myself
and that was hell of work
thats why i wanted to replace it with the random corridor
which will be even easier due to the fact that i already know how to make floors

@grim ore one last thing for the evening to expand on that, add your blend target setting the location, set it for 1 second, then move your cutscene itself forward 1 second, firing this event either On Create or make an event that fires at 0.0, then it makes a nice smooth transition to the cameras. ^_^

do i need to restart the project or something?
You mean live code?
no its not enabled
ill try restarting

is there some way to do that besides restarting? or should it just be working anyhow
i closed the blueprint editor yeah
but to get it to work had to close whole project
yeah not sure, just tried with new sturct and its popping up no problems now
maybe to do with it was first time i had created a C++ class
oh well, problem solved, when in doubt just restart 😛
well i just added a new struct, did compile from editor, then in blueprint editor it showed up

hey all
I have a questions regarding what would be considered "good game programmingphilosophy"
I'm creating a platformer and my character has a health system (in the character BP), I'm following this one video out of curiosity (create death zone) and noticed that the death zone ignores the health system and simply respawns the player at the nearest checkpoint
now my issue with this is I'm planning on creating enemies, objects, death zones, etc. how should I got about doing this in terms of the accessibility between these entities and the health system, should they all cast to the character which in this case has 2 variables max health and current health in order to do damage and kill?
Or should I create a middle man so to speak a blueprint solely for the health system for these entities to interact with?

I have tried to implement this feature with FRuntimeFloatCurve,but I want to draw a waveform instead of a curve.
Does anyone know how to do it?
Thanks.

Do you need to draw it by hand? Theres all sorts of trig functions available.
empty marlin
@supple totem
No, Can you provide some examples?

havent really used them except in c++
float DotMethod = FMath::Sin((FMath::Atan2(DiveVector.X, DiveVector.Y) - FMath::Atan2(LookDirection.X, LookDirection.Y)));
and this looks like a tutorial on using sine waves to move objects
youll want to look into trig math, and how to adjust the shape of a sine wave
usually you use multiplication, addition, w/e to adjust the shape to what you want

how to rewrite this in the ue4 ''vec2 uv = (fragCoord - iResolution.xy * 0.5) / iResolution.y;''
light coyote
@loud wraith
I think what you want is to do the logic on your character. That way it is alwais there and nice and accesible.
And what i like to do to make conditions in this kind of stuff, is to assign a tag(not allwais, and is up to you,,, 1000 ways of doing it).
That way you can use it as a condition,,, so... if death zone begins overlap, if actor overlapping has tag Enemy or Pawn, then those will call death function.
What i mean is that, as an example,,,, you dont want the bullets of your main character to trigger your own death.

hi guys! is it possible to call exec (console) functions from the command line?
light coyote
@plush yew
Skeleton is just your intermediary in animations.
Same as in texturing you have your UV coordinates(property of the object) as an intermediary between the object and the textures.
Skeleton would be your middle men that makes sure they can work together well. It would be crazy to animate each individual vertex 1 by one.
You use the skeleton to Weigh the object vertex to a certain bone of the skeleton.
Value of each vertex can range from 0 to 1, that 0 to 1 represents a percentage,,, 0,5 would be 50%,, and what that means is the amount of influence the bone will have to that vertex when it moves.
Ex... in a robotic arm, pieces are made of metal, metal does not bend, therefore, the bone wich turns a metal piece will have all of those vertex to be at 1 , so if the bone moves, the piece moves at 100% with respect to it.
When bending and stretching can ocur, is when weighing something becomes a pain in the ass,,, each vertex can have a maximum value of 1, so if 1 bone has 0.5 effect, if another bone has to have some influence aswell, it can only have that extra 0.5 left.

@light coyote we got a massive collection of very high quality assets in our studio, but we cant get them to look very good in UE4
its always missing that... sharpness ? its looks blurry and pixely compared to our other renderings
i have seen scenes made in UE4 that look really sharp and nice, but i cant achieve that look here
light coyote
@viral fractal
Make sure you are in High Quality and all of that.
And now is up to lighting and post processing.
So.. put a post process volume on your scene, and make it unbound so it afects the whole scene instead of just what is inside of it.
Mess about with all the stuff it has.
@dim merlin No, i mean select your decal to wich you dont want shadows casted on to, and make it a stationary object so shadows wont be casted on to it.
dim merlin
@light coyote i tried that, but it was still receiving decals
light coyote
Well i dont
@viral fractal They are lots and lots of stuff, so be prepared to get confused xD
You have to activate them first, and dont forget to make it unbound or you wont see any changes.
One affects the other, and this one seems to do sort of the same thing in a sense.
And aouldn it be better to lower lights and increase this,, , or the oposite ?¿?¿
See if you can find a propper workflow because there is quite a bit of sience in the combination of lighting and post processing.
viral fractal
oof
this engine is a very complex construct
cant get an overview
at least it runs a lot faster now for some reason
light coyote
Things i can definetly say you will want to use for realism are.
Blurr by distance,, is there somwhere.
Flare efect, there somwhere xD
and adjust your ambient oclussion to fit the scene you are creating,, you can sharpen them, blurr them, make them stronger,,, and in real life they tend to be in most cases prety sharp in terms of them not blurring evenly like a gradient.
But of course if you then touch lights, atmosperic light, put fog, skylight,, things may change.
Get ready

boreal topaz
I have a random item spawner that gets my items from an array. what can I use to prevent it from spawning duplicates. also sometimes it wont spawn anything at all
plush yew
noone knows what's causing my issue?
pulsar fractal
@boreal topaz after you get the length of the array, you have to subtract one before plugging it into the max int part of the random node
Because length starts counting at 1, but indexes start at 0. So for example if you have 3 items in the array, you can get Index 0, 1 or 2, but your function has the possibility to look for index #3, which wouldn’t exist unless you have 4 items in the array. So just subtract one first
light coyote
@plush yew It seems to me that your condition in the copashell is not beeing true
Have your bluprints as a small window and press play to see what happens
pulsar fractal
@plush yew hey, in your shell AI settings you must enable “auto control on spawn” or something like that
light coyote
@plush yew
Search for a key in the keybord, and plug it in so you can force cupa death with the key
pulsar fractal
@plush yew don’t remember what it’s called exactly, maybe AI possess? You must set it to control the actor even if you spawn it through spawn actor, because by default it only does this if the actor was in the level originally
Richard could have a better answer, I’d try both
light coyote
He is not really using ai, just an object that moves and if collided, something els happens
boreal topaz
thank you @pulsar fractal
light coyote
@boreal topaz What @pulsar fractal says
you can get the lengt and sutract one to get the last item
And there is also a last index wich may be usefull aswell
boreal topaz
sweet. thanks all
pulsar fractal
No problem, and okay my bad I thought it was ai
plush yew
@light coyote the condition is true by default also that doesnt explain why the collider doesnt work on the spawned koopashell but it does if it's originally in the level and yeah not using a behaviourtree or aicontroller or anything like that @pulsar fractal
pulsar fractal
Are your components set to Auto Activate?
light coyote
I was thinking when is it considered ai right now @pulsar fractal
Because a door is not really ai, dough it can be i gess,,,
But i am gessing is when things are not predetermined, and it will react with certain behaviour to changes in its sorroundings.
So to sa, if it jumped when an enemy is 1m away, and you spawn enemys at random,, i think that would be considered ai
@plush yew Send more pictures of everything in those bluprints
plush yew
@pulsar fractal @light coyote i just put auto possess ai to "placed in world or spawned" and now it both behaves the same when using spawnactor or spawnai but the collision still doesnt work properly however it does when it's placed in the level instead of spawned
@light coyote literally all there is to it
pulsar fractal
@light coyote I think you’re right, AI is considered anything that has the ability to change course of action based on a variable I read somewhere. In unreal’s case with regards to my initial method to fix his problem though just would mean it needs an AI controller. For fun, I made all my animal AI without any AI script I used all variables and random location moving
plush yew
i really dont understand why my collision doesnt work when spawned
pulsar fractal
Are you trying to do something when it hits the actor? I think you’d need to tick generates hit events
plush yew
collision with the ground works however but not the player for some reason
light coyote
@plush yew unplug, your condition,,, plug your event tick straight to add movement input
plush yew
no i dont have any collision triggers
there's no condition for collision
the collider is just there
the problem is not the movement
it's the collision that doesnt happen
plush yew
@light coyote thanks, that did the trick
light coyote
But what?
Im curious now
The colision?
Or the plugging tick to movement ?
plush yew
@light coyote checking "no collision fail" in spawnai from class and the same would work with spawnactor and one of the collision override options if autopossess on koopashell is set to "placed in world or spawned"

I'm trying to save a specific setting for a game I'm working on. (It's not my own work, but I'm just doing some fixes.) I tried attaching it to the save data that's already being saved, and it worked. Unfortunately, I need to load the data before the main menu. Currently the game loads the data at the main menu. Trying to move the loading process earlier causes a lot of bugs, due to this game being full of spaghetti code. Are there any obvious quick fixes or best practices for saving a tiny bit of user preferences?

you have to have them as short sounds
you can use ptch multiplyer to make sounds be longer or shorter, but you obviously distort the sound
and is not the original anymore
if the step is short, you can just rplay sound again and again

@hoary silo Im giving a look at it, and is little tricky.
I think that the best you can do is to put small colliders in the characters feet, and tag flor elements...
That way you can also identify if is wood, or water or whatever

@pulsar fractal do you remember my blueprint from earlier, with the item spawner array and you said to subtract 1. if I do that will it ever spawn the very last item in my array list if im subtracting 1?
light coyote
But it will be much much easyer to put triggers on each feet,,, and they allow you to do much more aswell
brave lark
whats the command to put in the config files to disable auto exposure?
pulsar fractal
@boreal topaz yes it will spawn it. If you have 5 items, they are seen as 0-4. If you get the length, you get 5. Subtracting 1 gets you 4, so when you get a random integer between 0-4 it can pick the last item (4)
Length function starts counting from 1, arrays start counting from 0. The -1 solves the difference
boreal topaz
oh so it doesn't random every single 1. it grabs random once and goes from there
pulsar fractal
I’m not too sure what you mean
Another option is to shuffle the array, then always grab index 0
pulsar fractal
Okay no prob
pulsar fractal
If you added the -1 where we talked about, the function itself looks good (id also change the spawn condition on the spawn actor to try adjusting but Always spawn). Maybe it’s a problem with whatever triggers the spawn actor function

Anybody here know how to make an ability, like healing linked to a HUD element?
autumn elbow
There are tons of tutorials on YT for that.
hollow frost
Such as?
open eagle
so I'm trying to add an item to the "back_pocket" socket of my player. After I add the item to the player as a static mesh component, I attempt to select the items parent socket. When I attempt to do this I am given the message "cannot change socket on inherited components". Does anyone know what the definition of an inherited component is? Or how to make my component not inherited? Searching on the unity wiki, I cannot find a definition for inherited components
hollow frost
@autumn elbow I had to go out of my way to implement healing functions into my game. And while going off no tutorial.
@autumn elbow DM me a link to a tutorial, and I'll see if it works.
autumn elbow
search 'unreal health bar'
hollow frost
@autumn elbow I can show you the code I used if need be.
grim ore
@open eagle and inherited component is a component that is part of the parent class. We don't know what you are using or how it is set up so i dont know what else you need
open eagle
@grim ore is there any way to change the class of a static mesh object?
grim ore
no? and that would be weird in general
marsh swallow
? isnt Static Mesh a class itself.
hollow frost
@autumn elbow What I need specifically is a cooldown for an ability, like say, a stim pack.
grim ore
I think we can help you more if we know what you are trying to do and where the issue is. If you are just adding something once to a socket it's as simple as adding that mesh to the player blueprint and setting the parent socket to the correct one
if you are trying to spawn in something and do it at run time it's fairly similar
grim ore
if you want a proper ability system learn the gameplay abilities system built into the engine but it's super complex and annoying to learn. otherwise break down what you want to do and implement each part like they are suggesting?
open eagle
Yes, so I have added the item to the player blueprint as a static mesh component. The next step in the tutorial I'm following is as you say: setting the parent socket. When I try to do this, it doesn't allow me to select anything saying "cannot change socket on inherited components"
maybe I've ticked the wrong box when importing the object?
grim ore
yes because you have no parent that has sockets
the parent is the item it is attached to, did you attach the static mesh as a child to your characters mesh?
so in the top left it should be Mesh (your character) then under it Mesh (your thingy to attach)
open eagle
There we go, that was the problem. Thanks MathewW!

Is there anything that u really want a runner game to include?
looking for some ideas
scarlet birch
Is there a way to have a timeline in a BP play in the editor?
scarlet birch
Like in construct?
How? Not in PIE, in editor
Can I select a variable and edit its value while playing the game in PIE, without adding something like an input to change it? I mean is there something in the tools that lets you do that?
random holly
Is there anybody that could please spare me some time to teach me how to set up animation montages please? I need to set up the swing animation on a axe holdable with the left mouse button
scarlet birch
I'm looking to speed up tuning things and adjusting variables that affect gameplay. I'm looking for an efficient way to quickly adjust a value while testing to see how it affects gameplay etc... . Right now I usually setup a input to decrement and increment the value and then play but that is not sufficient for the volume of instances I need to tune.
If there is not a built in method I could use suggestions on where to look to learn how to implement one.
grim ore
what more specifically are you trying to change and when?
scarlet birch
Variable values while an instance of the game is running
Like values that scale gameplay things, such as a force to a player, or the playrate of a fan blade
I'm looking to find a way to speeed that up
It's much faster to get to the right value when you can adjust it while playing
grim ore
if those are exposed you can change them in the editor on that instance
scarlet birch
right nor I setup something lke press 1 to decrment, press 2 to ncrement, but it's time consuming
well that update PIE while it's running?
if so that's a forehead smacking moment for me,
grim ore
it updates them in real time, it just wont save the values when you exit
scarlet birch
ok, I should have known that or figured it out
hollow frost
@grim ore Can you help me with implementing a HUD function for an ability cooldown?
scarlet birch
so I can select the the b in the eidotr and have a pie window open on another montitor and see the changes
@grim ore Thanks, I should have known that already. There's always something to miss.
grim ore
you should be able to yes, the details panel shows the current value on the instance in that editor window
scarlet birch
Ugh, I jsut realized yesterday you could select play from here and didn't need to move the player start
hollow frost
@grim ore I have the ability itself made, but all I need is the HUD element to show that in my game.
grim ore
do you have a HUD element set up for it?
hollow frost
I've attempted one, but it was faulty.
I can screenshot what I had and give it to you, if that helps?
grim ore
well you need a hud element to update, using UMG or the HUD system to start with
and is this element an image or text or how will it be showing them the cooldown
hollow frost
It should be an image with text over it.
The cooldown is 30 seconds.
Kind of like an overwatch ability.
scarlet birch
@grim ore Thanks a bunch that works. Monkey hairs and goose nuggets, I should have known that by now. Most other editors I've used worked that way.
grim ore
😃
@hollow frost well you need a hud or UMG element set up first before you can do anything else
hollow frost
Ok
plush yew
Hey guys how can i post in #looking-for-talent?
hollow frost
How do I go about doing that? I'm relatively new to this engine
I have a health and armor bar, alongside an ammo bar too.
scarlet birch
I was at a point I felt like I had stopped learning things with UE and over the Game Jam and the few days after I think I've learned a ton more about how to use the editor and debugging tools to speed up workflow.
hollow frost
@grim ore I'm trying to make an element for my health kit.
I can show you what I have, if need be.
grim ore
you can show your UI if you want sure
scarlet birch
Now If I could find a way to select an instance variable and increment and decrement it from the PIE window. Is that something that could be done with Blutility? I've not looked at using those yet. Like select a game pad input as the choosen input to change a value and then pick wich variable it will adjust?
storm burrow
So Unreal has 4 Rendering Teams plus the mobile team, console team and niagara team
Wonder what those 4 do.
grim ore
@scarlet birch it does sound like you can use blutility or the new editor widgets to do what you want but I don't really get what you are trying to do
storm burrow
I think Unity's rendering pipeline is more flexible than UE4's actually 😛
light coyote
In what sense ?
scarlet birch
The same way you jsut showed me I can adjust a value while pie is running by changing its value in the details pane. Only to be able to set an input like right/left bumper on a gamepad to increment decrement the value and then select before starting pie which instance and which variable to have changed
storm burrow
You can add and remove features much more easily and modify the rendering pipeline to fit your usecase better.
Scriptable Rendering Pipeline would be the key word. Epic is working on their own system for that afaik.
scarlet birch
I think I see the logic and if I can access instances from editor widgets or blutilities It should be doable. I'll have to look at those. I
light coyote
Havent really looked in to that, nor now much about it,, but just wanted to hear your opinion.

I would argue that this is not too bad looking ;P
light coyote
I belive that unreal is centred on making everything posible, accesible, and user friendly,,,, and they collide, and try to find out the best way
@storm burrow Have you seen Adam made in unity ?
Its amazing+
storm burrow
Yup, of course
I think rendering wise, both engines are converging
quite a bit
even for engines, in many aspects you now have a set of features that are kind of expected
ie baked lighting, visual scripting, realtime lighting, behaviour trees/eqs for AI, terrain, procedural vegetation
PIE/wysiwyp
Unity's ECS focus might give them an edge over unreal in CPU cost
if you have lots of actors
grim ore
at the expense of doing stuff sooooo annoyingly for normal devs
grim ore
yep you pick one and suck it up lol
light coyote
They are both great engines,,, but when i was learning unity,,, dont ask me why, but it anoyed me
storm burrow
I think for a non-coder, Unreal has an amazing UX
scarlet birch
4.23 is out?
light coyote
Unreal engine in the other hand,, i hear from people that are unity users that they say is complicated,,, for me is kind of the oposite in a sense
storm burrow
i think on the coding end, unity might be easier
but this depends on the person a bit too
light coyote
I gess,, and we tend to stick to what we know
grim ore
4.23 is not out, its in preview 6
scarlet birch
It doesn't say preview anymore but I can't find the release notes.
grim ore
It's a bug if you restart the launcher
light coyote
But for me, not having to remember how code is written, when do i have to put what, because sometimes you do, sometimes you dont etc.. For me, it made me actualy like programing in very little time
With nodes i mean
plush yew
man i'm on a roll, in the past 24 hours I've implemented a velocity tracking arrow for player movement and I got rotational lean to work (modifying the roll slightly when the player turns while running) I've been watching that GDC talk from the Overgrowth creator about procedural animation, it's a really excellent exercise to follow along with that
he provides no tutorials or anything, he just talks about what he did. I've been following along and trying to implement everything he talks about 1 by 1
grim ore
😃
plush yew
the rotational lean he has is different than mine though I think
right now I just have a simple solution that leans the character by multiplying the mouse X input by the player speed and rolling him b y that
I think I'm gonna change it to detect a delta yaw and roll it like that
but this is definitely good practice right now and it's a lot easier than I thought, if anyone else here is comfortable with UE4 but still kinda new and wants to challenge themselves, I highly suggest watching this video and trying this out too! it's very fun too, making this movement stuff work is rewarding in itself, but just even playing what you make is fun
https://www.youtube.com/watch?v=LNidsMesxSE here's the vid btw
light coyote
niceeee
plush yew
it's an excellent practice too, I'm not an animator, but I am a coder and being able to implement this stuff is a great replacement for real animations for now
of course, a talented animator is great. but for the time being gotta work with what is available! haha
light coyote
i remember how awesome it felt when i literaly just made a button do something,,, it feels like is your child, this thing that didnt happen, and now it does xD
plush yew
definitely
I'm surprising myself everyday haha
I always thought math was impossible for me and I'm just too dumb etc, I always struggled with math in high school
but I just threw myself at this over and over again to the point where I can do this on my own, very satisfying feeling
if you asked me 2 years ago what a 'delta' even was i probably would have just dropped out of my CS program haha
plush yew
yep
i use delta all the time now
i use delta in ways i didnt even know i should haha
like right now, i use delta to get the running lean of my guy because to get the speed of my character I just calculated the delta of the position of the current from and the previous frame
and i intend to eventually use the delta of the yaw to change the lean instead of the mouse
light coyote
nice
plush yew
BP definitely makes this all alot nicer
using a programming language you gotta figure out the math on TOP of fighting the compiler and hunting for missing ;
zinc rivet
my process for doing math in computer science is usually to figure out the math separately from the code
instead of trying to tackle both at once
plush yew

turbid plover
@grim ore did you complete a tutorial on every bp and shader node? Sometimes I'll look up something super minor and you'll have a nice 5 minute tutorial. Lol
plush yew
i learned all about vector math outside of code
light coyote
Nodes really are another laguage.
But moch more sintetised without losing usability(little).
Same as in languages you dont write the logic behind what multiplying is( A x B = A + A , B number of times),, in nodes you have a more extreme version of the same thing.
grim ore
Not all of them, there are too many to do without it being a full time job lol 😃 @turbid plover
plush yew
also, quick question on debugging. Say I want to watch a node's value in a function, what's the best way to do this? watching a variable in a function always brings up out of scope
I actually chose unreal over unity even tho i had background in neither haha
but understanding actors and stuff is similar to objects and classes
definitely, I really enjoy working with BP
also unreal has a lot of really nice tools out of the box already
makes working as a one man team much easier
light coyote
What really bogged my head at the start,, because i was learning both engines at the same time.
In plain words.
Is that in Unity, you drag the script to the object.
In Unreal you drag the object to the script.
But when you dont know you sort of assume that that is how things work and your mind hearts xD
plush yew
yep
I'm starting small and building up
not even worrying about levels and stuff til I get a playable character that I think works
right now I'm just trying to build up a nice movement system, gonna play around with procedural animations
then after that I think I will try to tackle combat
but not even combat against a feasible opponent, just player attacks and stuff
I used to do epee fencing in high school, and I recently played that student graduation project in UE4 called En Garde which is all about fencing which kinda inspired me
yeah I have a 'Master Character' C++ class that I will just make all NPCs a child of
me too, I've always loved pirates and stuff
and I always thought fencing aces was a really cool idea, I have this kind of idea in my head of like fencing aces are like western europe ninjas
super agile and deadly and master of acrobatics and weapons
yeah I really gotta go to town on the weapon system
if I can work with FaBRIK and CCDIK well, I would love to get a procedural parry system
where the parries connect with the enemy blade accurately

If I get all actors of class is the array returned in any specific order? By their age or name?

Ah ok gotcha

@grim ore What is the way it uses to determine all actors have been gotten ?

grim ore
it uses the internal iterator function to do it
light coyote
Sorry for that las one xDDDDD
plush yew
i figured maybe it would be in the order the actors show up in the world outliner panel
light coyote
@grim ore But what does it iterate against ?
I mean, there must be something that says, ok, you are done, you can stop iterating
plush yew
also sorry i dont think i got an answer so i'll ask again: is there a quick and easy way to watch a variable link in a function? when i do it now it just says not in scope. Do i really have to make it a variable and watch it in the main event graph? that seems too convoluted
light coyote
@plush yew That would be the instance number in a sense
grim ore
It's an engine function and I really don't know how it works, I would guess it internally keeps a list of the objects/actors/etc depending on which iterator function you are using which is why it's not a guaranteed order
light coyote
@plush yew send screenshot
real hound
Hmm I am in a pickle. Think I will go power shower and hope I hit my head really hard.
grim ore
like this is the actual code for get all actors of class ```void UGameplayStatics::GetAllActorsOfClass(const UObject* WorldContextObject, TSubclassOf<AActor> ActorClass, TArray<AActor*>& OutActors)
{
QUICK_SCOPE_CYCLE_COUNTER(UGameplayStatics_GetAllActorsOfClass);
OutActors.Reset();
UWorld* World = GEngine->GetWorldFromContextObject(WorldContextObject, EGetWorldErrorMode::LogAndReturnNull);
// We do nothing if no is class provided, rather than giving ALL actors!
if (ActorClass && World)
{
for(TActorIterator<AActor> It(World, ActorClass); It; ++It)
{
AActor* Actor = *It;
if(!Actor->IsPendingKill())
{
OutActors.Add(Actor);
}
}
}
}```
the TActorIterator<AActor> is the magic part
plush yew
like this
real hound

grim ore
yeah watching variables wont always show the variable since if its not in scope (currently valid and being used) it wont show up. There is a blueprint debug watch window but I don't know if it would work any better
light coyote
@grim ore You are not german in any sense right ?
I meant it cause it reads agresive xD
grim ore
and yes you would have to watch it outside the function because it's only valid in the function that's the way scope works. An alternative might be to print it out or use a debug display to show it on the screen?
and no I don't think I am german lol @light coyote

@plush yew They are fucking things up.
Pound has gone down a lot since last years, and generaly speaking, as a team, you can obtain more benefits.
What this is causing is instability, and big companys dont like unstability.
Because , like in venezuela, just as an example, the government was taking away property from big companys.
If they would have known, they would have sold and move the money elsewhere.
and that just makes uk lose productivity, so,, if same amount of money is in circulation, but less richer is the country, value of the unit is less, in this case, the pound
yep, at least a hard smak
cuple of years ago,, if you had 10000 pounds, you could come to spain and have arround 14500 euros
now is like 11500 or something like that
ohhhhhhhhhh
10900
the actual conversion woulb be that, ofcourse intermediary takes comision, alwais do xD
if you went to oficial bank of the country, maybe you get exact exchance, but i doubt, cause now you are leaving them with the problem of having pounds,, someone has to deal with sending, or proving and destroying,,, someone is getting paid to do that

quick question, whats the best way to get some kind of small 2D thing in a game like in that GDC animation video?
to clarify, he had a 'run wheel' attached to his character, and the run wheel was just an X shape with smaller lines in between the lines o f the X, and he just rotated that to visualize the speed of the character to be able to determine when the animation would step vs stride
the bot thought the last pic i sent was explicit lol, hopefully this one goes through. You think he just used some of the native rectangle meshes and shrunk them down and made like a wheel BP that was just a collection of almost 1 pixel wide meshes? lol
real hound
How can I make a transparent cylinder as a component to check for overlaps?
Instead of using Capsule
plush yew
@real hound I think you can just add a Cylinder Component to your BP, and tweak the settings so it's not visible, doesn't have physics collisions, but does detect overlap
light coyote
@plush yew Ithink i sort of understand what you mean,,
you can make a plane alwais look at you if that is of any help
and if you want to make it move with respect to something else, you can make it a child of it
i dont know if that answers it or not
plush yew
oh a plane! totally forgot about those and never thought I would have any reason to use one. Thanks!
hm, do I have to make a child blueprint class, or do you mean like make a bp then add it to my character as a component
light coyote
yes, add it as component
plush yew
got it, thanks
real hound
Ok gotcha. Is there a more elegant way of only triggering overlaps for a certain class of actor other than casting to to the overlapped actor to check?
plush yew
I don't think so, you can probably get an array of all overlapped items and try to check their class like that? but still from their you will have to cast i assume
light coyote
I like using tags
plush yew
i havent used tags yet, i should probably learn soon though. I love casting to a class because I get all the functions of that class but I hear it's heavy on the system
light coyote
maybe certain things can be considered explosions, and explosions kill instantly,, ActorHasTag ¨Explosion¨ then kill, if not take damage,,, example
grim ore
casting to class is fine but casting WILL basically load that item so if it's a heavy item then interfaces would be lighter
plush yew
how do you work with an interface in BP?
grim ore
light coyote
@grim ore You should be promoting your chanel man, not the docs xD
grim ore
if you only want to interact with certain things you can just use an interface on them even if it has no functions or they dont implement them and use the Has Interface function to do a check
its a quick and dirty way to check if something is something for example, like "can interact with" or "can die"
real hound
Wiat but how would interface be useful for overlap events?
plush yew
when the overlap triggers, instead of casting, you check the interface for the function you want
grim ore
actors you want to check have the interface called I dunno BPI_CanInteract. When you overlap you check the actor with the Has Interface function for BPI_CanInteract and then do whatever
or ^^ you don't even check the interface you just do whatever and it will do it or it wont
real hound
And that is less expensive than checking with cast?
grim ore
as far as I know it is unless you are using soft references with the cast
for example https://www.mike-purvis.com/?p=377 and there is a talk about it on the UnrealFest videos this year
hard references, so like cast to XXX, will load up the object you are casting to
and of course anything in there that is hard referenced will load up
and then of course....
normally not an issue until you start getting into larger projects or you get one thing that tries to manage everything and then bam your entire game is loaded into memory at start
real hound
aah ok
grim ore
this is one of those just make it work and optimize it later if needed lol 😃
but since you asked, there ya go!
real hound
Thanks man.
random forum
I have a static camera for a simple arcade game. When my player goes halfway towards the top of the screen or bottom, suddenly the bullet particles stop being rendered. No, they are not GPU particles. Has anyone every encountered this?
mint sequoia
Nope, something super weird going on there
high sparrow
@light coyote You can get a better understanding by looking at this post🤣
but the plugin doesn't work anymore, its too old
marsh swallow
okay question because i just used it for the first time yesterday. what is a soft reference?
mint sequoia
A reference that isn't loaded until you tell it to
marsh swallow
i guess im confused on use case. lol
mint sequoia
If everything is a hard reference then everything loads when the game starts and remains in memory
The use case is simply anything that doesn't need to always be in memory
You don't start out using them, make your game then if memory consumption is excessive profile what's using it up and change what's possible to soft references
marsh swallow
gotcha. so in my instance where the its for the cinecamera lookat target. its just changing the hard reference to a soft reference
grim ore
if your item is loaded already its not a biggie.
real hound
Hmm what if do you do if you need a end actor overlap (due to its destruction) that also needs to check its distance? Will that work out ok? If the actor is destroyed and that triggers and end overlap event that checks its distance will it even get able to get what its distance was?
grim ore
a simple example is a character and 20 weapons, while you might only use 1 weapon at a time if your character has hard references to all 20 in the blueprint then all 20 will be loaded.
marsh swallow
so if i had 500npcs and needed them to exist to load other code for calculations but didnt want them on the map i would keep them in soft reference array or something?
grim ore
thats a good question,
it seems like a data table or some other central database that your npc's and your calcs could pull from might be better?
in this instance
grim ore
but in this case if you are doing calcs wont they already be loaded anyways? assuming you arent fighting stuff that doesnt exist in the game heh
marsh swallow
thats what im asking. 😂
see when we equip items, we spawn and attach
unequip will destory actor
grim ore
when you spawn how is the node set up? does it pull it softly from like a list or is it a hard reference of exactly that item
like if you spawn from an array of class names, that would be soft
marsh swallow
so im not sure i would care about the other 19 in our variable.

if you spawn with the actual class in the spawn node, that would be hard

its an array of a struct that contains a class

@grim ore When can I pay you to teach me all your Yoda ways? You're like the oracle!!

then that should be fine, it's a soft reference to the class itself

Has anyone figured out a way to put a big room inside of a small building? I'm playing with the idea of portals and level streaming rooms underneath the map.

does anyone have an idea to this question
@grim ore Any idea🤣
A lot of my problem was solved by ur youtube video, hahaha
@grim ore btw, nice video, really helped me
@light coyote The video you sent me also has two player controller, but what I want to do is more like two camera on one character and the two camera view put up as split screen. Thx tho, I appreciate ur time

Helloo
Well guys i wanted to makemultiplayer game for pc but there is one problem
I never done any of this and i need sources from which i can learn
In pdf
light citrus
Oh its ok to be on yt too
random forum
Honestly, I would start learning as much BluePrint as possible, @light citrus and starting small with little single-player games you can program. Then when you are comfortable with BluePrint go for a MultiPlayer game.
steep ferry
Well im learning c++ still
im like being pretty comfy with blueprints
but i wanna learn c++ too im like 15% in learning c++
@random forum Bump
@grim ore Hey sorry for bother, But remember the floors generator i wanted to do? I found even other way than modulo
light citrus
I hate single players games :(
random forum
For example @light citrus I think there are many difficult topics such as interpolation and network replication you need to learn to do Multiplayer games correctly....
light citrus
Idk it make me bored ti play it alone
steep ferry
in my opinion its impossible to start yout game maker hobby with multiplayer game
@random forum Exactly. Bump again

Baby steps... you'll get there! But you need to do baby steps

gaunt raptor
u can do it to learn networking
steep ferry
Altough

I still preffer making singleplayer games
gaunt raptor
maybe five
steep ferry
my opinion
gaunt raptor
six is too many to start w/ tho

I cannot pass an array through an event dispatcher, it gives an error with any type of array, is that expected? I feel like I didn't have this problem before
light citrus
I watched one video where one guy made game where he kill cubes
steep ferry
@light vigil Screenshot please?
light citrus
Cubes are spawned on every 5 sec and they are supposed to explode

random forum
My opinion is start small, end big. Don't start big. it can get you discouraged when these really complex things you want to end up with don't end up working because you don't have the foundations under your belt.
light vigil
The input is correctly tagged as NOT by reference
steep ferry
hm
light citrus
Idea for single player game?
steep ferry
Bruh
gaunt raptor
u need to focus on like
light vigil
Changing it to not an array compiles, making it an array and it breaks again
light citrus
Post apocalyptic survival xD
steep ferry
what kind of question is that honestly
gaunt raptor
making something with an objective
south ridge
Make an MMO
light vigil
And yeah, ultimately I would pin array to its input
south ridge
😄
steep ferry
you cant just
light vigil
But this data type in general stops compilation
steep ferry
ask somebody for game idea
light vigil
Regardless of having an input
gaunt raptor
focus on mechanics not genre or the end archtype
steep ferry
due to the fact its easy to burn out on it
try to think of something you always wanted to do (with limits of course)
gaunt raptor
lmfao definetly dont do that
steep ferry
lma0 thats what i usually do
gaunt raptor
do something to learn stuff
light citrus
Okay ty xD
steep ferry
Well just learn
gaunt raptor
like a platformer with 5 mechanics no more
steep ferry

gaunt raptor
u start with moving around and interactions
steep ferry
platformer games are ga-
gaunt raptor
expand from there

Ok that was a joke lol

What are platforms, i yesterday downloaded unreal and tryed learning as much as possible
steep ferry
Download Cemu emulator

Is that game free?

Hey guys! I have a question about creating small single flame particles in Unreal. I'm taking an environment modeling class where we are using it and I'm still relatively new to it. If I use the flame that Unreal already has and scale it down, it splits into multiple flames which is not ideal for candles. Would someone be able to help steer me in the right direction? Thank you! 😄
thin tendon
Anyone here use Fuse for characters in Unreal? I need to know how to make hair and eyelashes translucent. Because Fuse packs everything to one material

@thin tendon isnt there an option to not pack them together?
at least the version I used years ago had one

Its all changed I to seperate it all I have to do it in blender

Im having some odd save game issues. I've made a save game that holds a list of actors that I can access in Editor just fine but in standalone despite it loading the actors are null. What gives?
blissful trail
i installed the voxel plugin from GitHub onto my project but when i try opening it it says try compiling from source and if i remove the plugin it works fine
thin tendon
I figured it out
pulsar fractal
@mint raptor i find that making a standalone game destroys refrences to actors so instead of saving actor themselves i just save the data such as the class and transform so that on loading the game i can spawn the actors from the stored class with the saved transform.
honest ermine
Hey guys, how do I change the actor that spawns when I playtest a scene?
dim plover
GameMode.
plush yew
Project settings > maps and mode. Those are your defaults. Can be over ridden elsewhere, look at pawn class documentation
serene sorrel
is there some reason a material with a mask works as intended in the preview, but when applied to a slatebrush the masking is opposite
serene sorrel
never mind, was a bug with the parametres being fed in

Hi guys! someone knows how to properly update an editor window after modifying it via Python Scripting. For example, creating new keys on a sequence via Python requires to close the editor window and open it again to make it work.

Guyz I need some help
I succesfully Installes Unreal Engine 4.22.But I cant open it.
It shows the loading screen.
And shows the project templates.
When I selected and clicked ok nothing happened
After some time It showed an error message and closed.
Please help
🙏 🙏 🙏 🙏 🙏
crystal wind
It helps to share the error message. Also your os version, and if you tried making a code or blueprint project.
If you've tried building a code project it'll require the right ide/compiler.
I could be wrong but you strike me as an absolute beginner, in which case your better off following along exactly with the beginner youtube tutorials that epic games made.
If you don't even have visual studio then avoid building code projects.
real hound
Yeah, I'm with Koi. I suspect you started with a code project and you dont have Visual Studio set up properly for use with UE. You need the VS C++ for gaming and another module/add-on.
crystal wind
And moreover, unless they've updated to 2019 you'll need to download something extra to compile it with the vs2017 compiler.
Since ms doesn't seem to have downloads for that ide anymore >.>
crystal wind
Oh thank god that saved people tons of headaches i bet. But not an easy task on their part.
cloud cobalt
And you can still install 2017 AFAIK, at least from the VS installer
crystal wind
I've spent like two days trying to figure out how lol >.<
Musta missed something.
@dry marsh But yes if your not understanding much of what i'm saying just watch the Epic Game's youtube channel, look for vids related to beginners. They'll show you how to do pretty much everything. You'd just have to follow along.
If you ask I'll provide a link.
real hound
Yeah I am using 2017, it just need the little addon to interface with UE. So you are saying 2019 is ready to go right after install?
crystal wind
I don't know, I've downloaded the compilers for 2017 and 2015 before trying to build ue4. Only have access to vs 2019 though as I couldn't find downloads for the earlier versions of vs studio on ms's website anyway. But it seems epic was smart enough to port to the new ide to keep things easy for beginners.
real hound
I think earlier versions can just be selected from the installer. But I don't spent a lot of time in VS. More of a sublimetext fan
crystal wind
Meh it's got a good debugger and has fair syntax highlights but honeslty vs code is nice and light weight for me ^-^
A lot of libs depend on vs sadly though.

Hi Guys, i'm cleaning some big models i imported from some CAD app, i have to process the cleanup in different project and then i am thinking about merging the projects, is this something that is easy to do ? (the merging of projects i mean)
crystal wind
If your spamming a lot be wary that transparent things especially with dynamic lighting can hit the gpu hard, if your's doesn't have gddr5 vram your probably in trouble there.
Merging projects in what software?
crystal wind
There's no way to easily merge projects, you can export meshes form them, you can copy/paste blueprints and rework the bugs, but it's not easy.
OHHHH
Yeah you can export that.
Be wary
It'll export the entire project.
Or everything that was on scene.
If I can remember how give me a sec.
That may do it.
sand sparrow
Anybody know how to make sand particles blowing in the wind?
I have a sand material, and I already sculpt my landscape, I just want sand particles right above the sand “blowing” to give it more of a realistic look.
inner cloak
I have a model file, the one i cleaned in the project, now i want to work on part 2 in a new project and bring the cleaned 2nd project back to the first ...
crystal wind
Spawning particles like you'd do normally, but have them move in a direction, probably.
inner cloak
the reason i have a 2nd project is due to the datasmith exporting process
crystal wind
I mean spawn them using an actor.
If your moving more than just models between projects it'll be difficult.
opaque edge
Koi what projects have you worked on? I'm just curious. 😛
inner cloak
Koi, not sure fbx will be so good, it has a few flaws that i found in the last few days
crystal wind
Lots of prototypes that never made bread and lots of projects I helped with that never made bread either. To be perfectly blunt.
In multiple engines and custom engines.
Oh it does?

Cool. How long you been using UE?

Ok thanks, I’ll check to study and see how I can put that to use

In programmy speech...
for(uint32 i = 0; i < 20000; i+=2000)
Sorry I don't read algebra to be honest >.<
Lots of particles will be difficult on the hardware and it's worse if you have a bunch of actors (one for each particle) so you'll want to find a way around that.
sand sparrow
Interesting

Conan game has nice sandstorms

Conan game?

some are very big .. wind particles should not be that heavy if only on the floor
crystal wind
Fair advice there.
inner cloak
Yes, Conan Exiles
crystal wind
Are those colliding with the ground?
sand sparrow
I really wouldn’t know, they don’t mention anything on the description
crystal wind
I'm half wondering if that's a fancy shader...
inner cloak
this looks like a big texture being translated
crystal wind
Yeah that seems closer, somehow the particles are moving along with the curve of the terrain.
O . O
he's right
If you look at the sharp edge of the terrain at the mound...
You'll see there's no particles.
Kind of like how normal maps look fake when your viewing a wall from the side.
