[tough stream]

😃 awesome

[stray smelt]

i've loved every patch for UE, but who had the idea of moving the "modes"-shortcuts

and now it's creating a new window/assigning new space, which is even more annoying

[fierce tulip]

if they are all on top of eachother, not even 1 millimetre

[autumn latch]

This is the last one, I'll try to do it now. @tough stream

[gray kindle]

Hey, why would this happen to my render with anti aliasing on in movie render queue? turning it off makes everything work perfectly

[willow tinsel]

[sterile tulip]

Anyone knows how big this map would be?

[jade carbon]

Hi, does anyone on here specialize in making realistic weapons in multiple weapons classes. ??

[plush yew]

hi guys

i have a problem

when i tried to make

make skeletal mesh Child of Camera

it gives error

and says

inherited and cannot move

anyone ?

no one ?

[grim ore]

inherited means its part of the base class

so its hierarchy and what it is canot be changed, so no you cannot do that

[plush yew]

is there any way to

make it child of camera ?

[worldly lynx]

i need this function in C++ , how can i access this?

[thick herald]

https://docs.unrealengine.com/en-US/BuildingWorlds/Landscape/TechnicalGuide/index.html

[plush yew]

how do I make my AI only affect one actor from the same class?

[grim ore]

@plush yew not if you are using that class, you cannot move an inherited components hierarchy

[plush yew]

i got it setup so it can find the closest one, but i dont know how to use that to make only the closest actor it found use the bp

[grim ore]

so you need to use another class and build it the way you want, or do something else

[plush yew]

what happens

if i

duplicate it and

try again

can it be ?

[grim ore]

@worldly lynx look for that node in the C++ source then. Its part of Scene Component from the looks of it, so it should be in the scene component source file.

duplicate what?

[plush yew]

I got this bt task

blueprint

[grim ore]

the class that the blueprint is made from determines what is part of it, that is why those items are inherited and you cannot change it.

[thick herald]

smells Crusher here

[plush yew]

and this is the bad task to take away 1 float from another actor

[grim ore]

@plush yew so that task sets the closest food on the behaviour tree. what is the issue?

[plush yew]

idk how to continue from here lol

i want it to use that event but only from the closest actor

[grim ore]

so only the closest AI to that food would do the eat? what does the others do

[plush yew]

their own thing, the problem is the custom event fires on all the actors

so that obviously doesnt work

[plush yew]

oh okay well, is there another way to where i can look with camera the character will set it rotation same with camera

[light thunder]

Why is this coming back empty?

[plush yew]

my english isn't good

[grim ore]

yep so you would need to not have it on the BT for all the AI, or you need a way to block it, or you need a way to only trigger it on one AI like a decorator

[plush yew]

it does trigger on one AI, the event it triggers is on another actor, like a resource

but I got copies of it

like 3 berry bushes for example

[plush yew]

?

[grim ore]

the default third person character can rotate with the camera, you just need to change some of the settings on it

[plush yew]

how ?

[grim ore]

@plush yew so you have 3 AI, 3 Bushes, and you want one bush to be active and one AI to go to that bush?

[plush yew]

i'm idiot

😄

[grim ore]

there are rotate options on the character you can adjust, look in the details for them

they will rotate the character with the camera

[plush yew]

okay thank u so much

@grim ore I got a bunch of AI, A bunch of bushes, One AI goes to the bush and takes one berry from it, all bushes now have 9/10 berries instead of just that one 😛

The AI can find the bush, and move to the bush, But I dont know how to isolate that bush

I hope im making sense

[grim ore]

so the issue isnt with the AI it's with keeping track of the berries on the bush?

[plush yew]

yea 😄

[grim ore]

so then whats the code for the bush, how does it track the berries

[sterile tulip]

I didnt understand this

Can you tell me how big that would be in the image I have send?

[plush yew]

its just a custom event that subtracts one from a float

[sterile tulip]

@thick herald

[grim ore]

https://forums.unrealengine.com/development-discussion/content-creation/28153-calculating-exact-map-size this says 1 vert is 1m according to the post if using normal scaling

[sterile tulip]

how much would that be then?

[plush yew]

@grim ore i can't find it

[grim ore]

but what float is it subtracting from? is this a float on the bush itself or a float on something general

[plush yew]

where am i need to look

on the bush itself

[clever vault]

how to make all the windows that open stick to this ?

[grim ore]

that says your resolution is 8,161 verts so 8,161 meters

[plush yew]

what component am i need to look

[sterile tulip]

do you mean 1 vert = 1 m or 1 km?

[grim ore]

my first post said KM, I mean M. the forum post has more details

[grim ore]

@plush yew if the bush is being changed by removing one, then how are you testing that all the others are at 9/10 now?

[plush yew]

cause the custom event fires for all the copies of the bush

[grim ore]

@light thunder Component Tags are not the same as Actor Tags is why

[jolly jungle]

is fusion 360 any good for game modeling? I learned the basics of it for 3d printing and it is way more intuitive to me than something like blender. Is it a viable option or should i just suck it up and learn blender

[grim ore]

@plush yew Where is your actual code that calls pick berry at?

@plush yew did you look for anything that deals with rotation in your character?

[plush yew]

i looked but

cant see anything

the highlighted part

@grim ore how can i do it

[grim ore]

@plush yew then you didnt look. there are 3 things that come up with you start typing rotate in the character and you didnt try anything

@plush yew that says your NPC is calling pick berry AND the berry is being told to pick berry. why both? also you are picking out a berry in the task are you not why is it trying to find a random one?

[plush yew]

ah the pickup berry is for the AI to hold one, its not really part of it

[grim ore]

ok so the second part is every time this task is called its going to find a random berry and pick it.

[plush yew]

Yea, Cause I dont understand how to use the one where the AI is

I got the info

its in the other task

''find nearest berrybush''

[grim ore]

the other task should store it on your blackboard

[plush yew]

it has a bbkey and an object

[grim ore]

this task should get that from the blackboard and interact with it

[plush yew]

ah How do I do that?

[grim ore]

how did you store it?

do the opposite

[plush yew]

its a variable or a bbkey

[grim ore]

you store it in a blackboard value, now you get it back out in the other taks

then you can do your pick berry on that object

[plush yew]

like this @grim ore ?

[grim ore]

that should get the value yep

[plush yew]

thanks 😄

[sterile tulip]

Where is the world proporties to change the z death zone?

I need to put the death zone lower so it doesnt kill the character

where do I do that

[exotic thicket]

it's called Kill Z

it's under World

[sterile tulip]

where is world?

[plush yew]

hi again

can i play an animation in event graph

[exotic thicket]

@sterile tulip world settings

[sterile tulip]

I dont find it

[exotic thicket]

you can just type in kill z into the search box

[grim ore]

@plush yew you can by using the play animation or play montage nodes

[plush yew]

okay thanks

[grim ore]

you can also just disable it if you are crazy

[sterile tulip]

what searchbar, im new to this @exotic thicket

[grim ore]

World settings?

[exotic thicket]

look at the picture :)

[grim ore]

you might not have it open by default, its under windows

[exotic thicket]

it should probably pop open also if you go settings->world settings

[autumn latch]

u can use play animation, play anim montage, play montage nodes

[plush yew]

thanks

[sterile tulip]

thanks mate

It worked

[exotic thicket]

[light thunder]

ugh, saw that, thanks

Hey Guys, How I can prevent this agressive compression in ES31?

SM5 vs ES31 same texture :/

[plush yew]

is it need to have project 😄

mhm

[stark marsh]

i have so many ideas for games but then when i put them from my mind into unreal it doesnt give the same feelings as how it was in my head

[humble bison]

Hey guys, I'm pretty new to unreal engine and this is my first time trying to launch a project to my android phone, I keep getting this error:

LogPlayLevel: Error: AAPT: error: failed writing to 'Z:\app\build\intermediates\runtime_symbol_list\debug\R.txt': The data is invalid. (13)

Anyone know the cause of this or how to fix?

[twilit jasper]

Hey guys!

Sorry if this is not the right place; I'm a systems engineer and I do web / mobile apps for a living. I recently decided I could give game dev a go.

I've been trying to familiarize myself with the editor (so good pretty far) and I've tried setting up a small forest scene. I've found a pretty solid blender tree generator and went ahead and imported it into ue4. I was incredibly exited and I used the foilage editor mode to make a few tress and then I realized that whopsie dopsie, my FPS...

Turns out that as many of you are aware of, transparent materials often used by leaves cause a lot of overhead. But I was not using any, even the shader view optimization is all green on trees. I must rekon I do have tons of leaves on each trees (I would say like 1K??) It's a lot, I know, but is it enough to make such a FPS drop (Consider I can't place more than ~ 10-20 trees till I get -10FPS (GTX 1060 TI). And that's with just those trees + landscape (Nothing else, no materials even take place here). I also have a simple collider in place so I must be doing something wrong at some point but I am sure somebody here can help me. What should I do? Where should I profile? Should I just really understand that I can't place that many leaves? Tree people, help me!

The tree, for reference

[crystal dust]

Well what I use for leaves is have a PNG image of a group of leaves

and project them onto planes

[plush yew]

bruh

[twilit jasper]

Do you often build your trees from the ground up or use some sort of generator?

[plush yew]

ya png is the way to go

[crystal dust]

generator, sapling tree gen

allows you to make trees quickly and optimized

If you want the leaves to look better

[twilit jasper]

Ah, I was using Mtree

[crystal dust]

You can have one plane represent on leaf

and have an image of a leaf

and once again project it on both sides of the plane

[twilit jasper]

Yeah I sort of understand what you mean with this!

[crystal dust]

Also make sure to have the curve resolution of the trunk and branches to be a good amount

[twilit jasper]

I will then have to optimize those png for transparency issues right?

[crystal dust]

I've never had transparency issues

[twilit jasper]

Would't u see this kind of thing with those png?

[tough pagoda]

Stoopid question. Why UE use CPP? Not C# for example.

[twilit jasper]

Why not?

[crystal dust]

Might need to make an alpha

Not sure

[tough pagoda]

Hm...

[twilit jasper]

There's tons of programming languages, why is it not possible for an engine to use c++ instead of another?

[crystal dust]

I'm not very familiar with Unreal Engine's PNG workflow

[twilit jasper]

Thanks a lot @crystal dust , will dig a bit more about it!

[crystal dust]

No problem

Make sure to keep an eye on the triangle count when modeling

[twilit jasper]

Is there a place to see it in blender?

:p

[crystal dust]

Yes

Give me a minute

So open Blender

Look at the top left of the UI

Under Edit, select preferences

Click on the first category, Interface

Then under the editors drop down, open up the sub-dropdown, status bar

[fierce tulip]

@twilit jasper why not download a free marketplace pack with trees and see how they did it?

[crystal dust]

Now check the 'Scene Statistics' option

[twilit jasper]

I like learning by doing, not by copying

[crystal dust]

that will show you the triangle count on the bottom right of your screen at all times

[twilit jasper]

Yikes

[fierce tulip]

i didnt say copying, no use reinventing the wheel

[crystal dust]

yeah not a very good triangle count

[twilit jasper]

Would you say creating a tree is re-inventing the wheel tho?

I would have had this issue regardless with something else I would say

[crystal dust]

they're talking about observing a marketplace tree, but don't copy it

[twilit jasper]

I can say the same hahahaha, damn it

[crystal dust]

so for the tree gen I use

[twilit jasper]

Ah right, gocha

[crystal dust]

it's a default one

go back to preferences

and enable sapling tree gen

that tree gen has a lot more optimization tools

[twilit jasper]

Sorry for the missunderstanding, I could totally check out a tree somewhere done in blender that is built for games (performance)

[fierce tulip]

your tree leaf/branches are set up as transparent?

[twilit jasper]

I have no idea, Have you used Mtree before?

I'm gonna try that tree sampling now

[fierce tulip]

talking about ue4 material part

because this is a ue4 discord

[twilit jasper]

I didn't even set up the material to be honest

i realized the bottleneck by just placing the trees there

[twilit jasper]

yeah I know, that's why I came here 😄

But you would just not model stuff in ue4... right?

[fierce tulip]

again, was talking about the material

[twilit jasper]

But if the tree has no material applied, should that matter? let me give it a quick look

[thorny sedge]

Hey everyone! I am in desperate need of some help. I have been working on a project and every day I zip a file of it up on my computer as a backup.

Now my project stopped working and I went to a backup file. But the backups are loading parts of the current project and I can't get them to fully revert.

Does anyone know where persistent files are that would stop me from fully reverting?

Or does anyone know of a better way to save backups of games? I have a really hard time having backups of games and my projects always crash.

[fierce tulip]

better backup: look into version control (keywords: version control, perforce, tortoise svn)

[thorny sedge]

thank you

[fierce tulip]

C:\Users\YOURNAME\AppData\Local\UnrealEngine
can remove all this, that might help

[thorny sedge]

thank you very much

[fierce tulip]

(though generally removing the deriveddatacache folders should be enough)

[twilit jasper]

I made the leaf material (green) go translucid in the material editor in blend mode:

Seems kinda the same result tho

[stark marsh]

can i reset my animation bp back to its original state?

[fierce tulip]

its nice that you jump the gun on things, but all i asked was if the leaf part of the mesh was set to translucent, because if it was i'd suggest to try a masked approach instead.

[stark marsh]

i messed some stuff up and cant get back so can i reset the blueprint

[twilit jasper]

Ah alright, sorry. I'll tree the other tree gen + PNG leaves now, let's see if I can get a better result 😄

[stable relic]

Anyone?

[plush yew]

My animation blendspace isn't working

And I've been at this for 2 daya

I'm getting the idle pose to work but walking doesn't animate they just float around in idle pose

[sterile tulip]

I installed an asset pack

now this popped up

[fierce tulip]

no need to import em, means the asset pack has external content like jpg's or meshes

[sterile tulip]

Why is this asking me this and where does it want to import my things

external content from where?

Also what will happen if I import it?

[fierce tulip]

you are just wasting time if you import em.
its just an additional folder from the asset pack that contains the base files

.fbx, .ase, .bmp, etc

[lapis bronze]

Unreal converts everything into .uassets
the seller of that pack included the actual source files for some reason

absolute madman

[fierce tulip]

source files, thats the word i was looking for

well some devs appreciate having the source files, like me

[lapis bronze]

perhaps, but you can always export them back out

[fierce tulip]

depends on the files

[lapis bronze]

i havent found one i couldnt do it with

[fierce tulip]

plus more clicks on my side

[sterile tulip]

So if I import it

Will this asset pack take double the file size?

[grim ore]

@plush yew did you try posting your actual code in #animation or somewhere for help?

[fierce tulip]

it will just replace the one thats already there

[sterile tulip]

so I wont have it twice

[tiny sonnet]

why doesnt the player controller recognize the umg and saving it, it makes no sense

[honest lily]

hi

i need some help

well i made a tpp / fpp camera change with Keybind V

when i press "Play" i press V it goes to FPP but when i press it again it doesnt go back to TPP

[brittle widget]

Are you deactivating the cameras anywhere? I think you probably only want to one active camera.

[grim ore]

@honest lily your B is never being called on your flip flop

[honest lily]

wait

where should B plugged in?

[grim ore]

also you have the same input action twice?

[tiny sonnet]

instead of having that input twice

connect one of them to other Bs

[honest lily]

wait im confused

[grim ore]

do you know how a flip flop works?

[honest lily]

hmm a bit

[grim ore]

based on that code you do not

[honest lily]

im not that experienced sry

[tiny sonnet]

a flip flop switches between 2 codes each time

@grim ore ayo, can u help me above?

[stable relic]

Does anyone know how to prevent a texture being over compressed in mobile-ES31?

[grim ore]

it should look roughly like this

@tiny sonnetis that node executing when you are looking at it? it looks like it's not so it would not have ran which means that is has no value for you

[tiny sonnet]

yeah it is

its begin play lmao

and the player controller

its added to the viewpoer as well, but its not saving the data :/

[grim ore]

your breakpoint is on Servermessages

[tiny sonnet]

yeah i know

[fierce tulip]

@stable relic while i understand that its frustrating that your question is not getting answered, re-asking it over and over is against the #old-rules please respect them :)

[grim ore]

so... if its broken on that point, your node is not running in that frame

[tiny sonnet]

even if i make the breakpoint, add to viewport, its not saving

[grim ore]

then is the widget being created? show the execution stopped on the Set with the mouse over the return value after it runs

[honest lily]

should it look like that?

[tiny sonnet]

it keeps saying this, but it is still adding it to viewport, it litterally makes 0 sense

the widget is live and being created, its just a countdown

[grim ore]

so this is multiplayer, are you only doing this on the clients machine?

[tiny sonnet]

yes

[grim ore]

and that code is set to not run on the server?

[tiny sonnet]

no, its set to run on the player controller from begin play, with a dedicated server

[grim ore]

so the server is trying to run a client side only node and your asking why its not working?

[tiny sonnet]

its not the server trying to run it

its the player controller

[grim ore]

and the server doesnt have the player controllers for all players?

[tiny sonnet]

wait what

if the server was to run it, the UMG wouldnt show up in the first place, but it is, its just not storing it

see

[grim ore]

ok so... your missing the basics of multiplayer it looks like

[honest lily]

@grim ore i fixed that thx!

[tiny sonnet]

mainly just UMG, i lack most knowledge with it

[grim ore]

in networking items exist on the client and server for most things

so you have a main character and there is a copy on your local machine, and a copy on the server

[tiny sonnet]

yeah i know that

[grim ore]

in this case umg doesnt exist on the server but your code that is on the server is trying to access it

[tiny sonnet]

so where should i execute the UMG

[grim ore]

player controller (client) and player controller (server) are both running the same code unless you tell it otherwise

[tiny sonnet]

should i execute the UMG in the player pawn then?

[grim ore]

there are is server and is locally controlled and other nodes that you would run to restrict where it runs at

you would adjust your code to only run on the client

[tiny sonnet]

switch has authority?

[high turtle]

Hello, I am from Chile and I have a problem that I have not been able to solve with some animations, could someone help me?

[grim ore]

have you seen the networking compendium ?

http://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf

[tiny sonnet]

i litterally just switched to offline and had the same problem, its not a replication issue

[mighty copper]

Hey @grim ore would you be able to offer any assistance on unreal game launcher crashing on startup after it updates itself?

[grim ore]

@tiny sonnet which part is failing, the server only server message or something else?

[tiny sonnet]

the UMG is being executed but not saving as a variable

[grim ore]

use print strings to validate what is running what code, it will show if its a client or server

so after the create print out the return value name

[tiny sonnet]

its not a replication issue, i aldry checked that

and i used debug to check the returns

it said None

which makes 0 sense

because its going into the "add to viewport"

nvm, igtg, ill figure it out on my own

[grim ore]

This code works as expected and is what I am trying to get from you

[plush yew]

@grim ore

whats wrong here?

I thought you said it should work?

cast fails

[grim ore]

@plush yew is that object a tree? pause it using breakpoints and what is inside of that object

[plush yew]

It is im sure of it

[grim ore]

well the game doesnt think it is if its printing out failed on the cast

[plush yew]

see, its going to the tree

and thats the code that finds it

wait nvm Fixed it

[grim ore]

press F9 on the node that says cast to tree in your task, wait for it to pause, mouse over the return value from the Get blackboard value as object

[plush yew]

lol

thanks tho, made me realise im just stupid 😛

didnt specify the bbkey in the BT

[grim ore]

makes sense

[mighty copper]

@grim ore would you be able to offer any assistance on my epic Games Launcher crashing?

[grim ore]

I doubt it, thats not really part of the engine. have you tried uninstalling it and reinstalling?

[mighty copper]

Or know of anyone to reach out to directly... as the email support is being no help from Epic's end...

[grim ore]

and if its crashing what is in the logs

[grim ore]

check out the full log in the logs folder such as C:\Users\USERNAME\AppData\Local\EpicGamesLauncher\Saved\Logs

[mighty copper]

I tried repairing it... rebooted my computer and got it to load... then then updated itself and starting crashing again.

[plush yew]

@grim ore https://streamable.com/tw0yw8

it works man!

thanks so much!

[grim ore]

yay

[median hound]

where can i find that boolean in details?

[plush yew]

it kinda screws up when I got more AI tho lol

had it synced, nvm

hi guys

how can i make

if player press left mouse button for 0,3 seconds

gun will be shoot

blueprint

[mighty copper]

@grim ore I sent you a message about your question dealing with the log.

[gentle trout]

Anyone can help me?? Can i work in ue with my friend??

[grim ore]

@mighty copper I dont have DM enabled. You can paste the log here or see what else it might mention before the crash. As this is an epic closed source product there is no way to know the exact crash reason unless the logs say something beforehand

[plush yew]

mathew with DM's enabled would not survive haha

[mighty copper]

it won't let me copy/paste the log as it has too many characters but here is what I sent you.

[grim ore]

seems like part of the launcher cant install for some reason, beyond that we cant read the errors. I know the new versions install the epic online services side by side. have you tried running the launcher in admin mode?

[median hound]

yeah ive heard of ppl doing it

[stark marsh]

help im trying to get a combo system working

but when i do 2 attacks in a row to activate the combo i can only do that once and can never attack again

[grim ore]

what stops you from doing it again?

[stark marsh]

i dont know i think it might be something where after my second attack animation plays it sets my combo counter back to 0

[mighty copper]

@grim ore That is the only way I run the launcher is in admin mode... it avoids unneeded troubles...

[stark marsh]

https://www.youtube.com/watch?v=8CA4e818erY

i follwed this tutorial exactly excpet i only have 2 animations instead of 3

[sterile tulip]

how do I export them out

[grim ore]

@mighty copper yep I am out of ideas then. Unfortunately I cant see the actual crash source code 😦 Beyond literally uninstalling the launcher and deleting it from your appdata and folder then reinstalling you might have to wait for epic

@stark marsh why not follow it exactly and just duplicate one animation for testing and see if that fixes it

[mighty copper]

@grim ore Thanks for at least responding to me...and trying to offer help.

[grim ore]

if you cant start the attack again, what is stopping it? what does the attack look for when you press the button to start the attack

[minor grove]

Hi all, I just initialized a git repo in my existing UE4 project and my .umap and .uasset files are no longer showing in the content browser. Does anyone know what I can do?

huh...

[sterile tulip]

Hey, are you there? @fierce tulip

[minor grove]

oh no

[lapis bronze]

Right click - >asset actions
Something like that I forget

[mighty copper]

@minor grove goto #source-control, they may be able to help more in ther.

[minor grove]

TY

[stark marsh]

i have no idea what is going wrong

if i dont start the combat i can keep attacking normally over and over

[grim ore]

so then what does your button look like when you press it. what does it check for to make sure you can attack

[stark marsh]

like if i wait a short amount of time before attacking again i can keep repeating, its only when i initiate the combo it doesnt let me attack anymoe

[grim ore]

the video shows it resetting 2 variables back to false, do you do that as well?

[sterile tulip]

if I import the source files, where are the source files saved? I have pressed import on one, and now I have 10gb less space on my C drive, but when I go on my project file its still the same size @lapis bronze

[lapis bronze]

Don't import the source files lol

[fierce tulip]

please dont random at me :)

[grim ore]

source files are saved where the source file was at, the engine doesnt change the source file it makes it's own version of it in the project

[lapis bronze]

He bought a marketplace asset pack that included source files

Big ood

Oof*

[grim ore]

ah then he should just delete them then

[sterile tulip]

where do I delete it

I pressed import now I have 10gb less space

[lapis bronze]

[grim ore]

you shouldnt have imported unless you wanted them and knew what you were doing

[fierce tulip]

yea told him not to

[sterile tulip]

but my project file did not increase in size

I thought its gonna save it in the project file

I was not gonna use this project

Now I need to find where it saved it

[grim ore]

it would have saved them in the project folder, or in the cache folder

[stark marsh]

i fixed it 😳

i needed to put an anim notify in my second animation

😳 😳 😳

ok now i need to fix up the messed up rootmotion

he slides across the ground forward but then snaps back in to place once the animation ends

[grim ore]

normally thats a check box in the animation sequence, or you can fix the original animation

[stark marsh]

oh and also how would i damage and enemy

[grim ore]

lots of ways, its going to be specific to your combat

[stark marsh]

and i want this to work with an equipped differant weapon

i want hack n slash style fast paced

[fierce tulip]

you might want to follow some tutorials and guides to see how and what.

we arent here to guide you trough the whole process

[grim ore]

there is an action RPG example project on the learn tab you can look at as well

[stark marsh]

so just go through the code and see what they did

[plush yew]

I just come here for key terms so I can do the search myself, though sometimes I understand wanting people to fix something you're beating your head into the wall for

[sterile tulip]

Do you know where the cache folder is

[plush yew]

@grim ore we have a learn tab?

Yea sometimes youre just not sure how to proceed cause you dont know what to look for

[stark marsh]

also i think for rootmotion i need to go in blender and just edit the skeleton of the mixamo character

then could i just reimport it

[grim ore]

@plush yew on the Epic Games Launcher at the top

[plush yew]

rootmotion? yea its need a rootbone or something

i dabbled in it

quite annoying

[stark marsh]

i wont have to retarget everything again will i

i wont need to retarget the mixamo mannequin to ue4

[plush yew]

no you need to add a bone in blender, but it has to be a special bone lo

[grim ore]

you might, it depends on how you fix it. If your animation is moving and you dont want it to move just tell the animation that in it's editor window

[stark marsh]

whats special about it? isnt it the location and rotation is something

[plush yew]

like Y Z locked, and rotation locked

parented to the hip or something

its just tedious

[grim ore]

root motion is when the animation moves relative to the world instead of relative to the animation basically. So it could physically move 100 units forward in the animation rather than in place (the other type of animation type)

[stark marsh]

i think thats what i want

[stark marsh]

because the combat im going for like darksiders the character moves around alot and jumps, spins etc

[plush yew]

mixamo doesnt have a rootbone tho so it doesnt work

[grim ore]

you can adjust it inside the editor if you dont want to fix the animation

[stark marsh]

i want to have them physically move

[grim ore]

even if the animation you want moves the character it doesnt mean you always want the animation to move the character

https://docs.unrealengine.com/en-US/AnimatingObjects/SkeletalMeshAnimation/RootMotion/index.html

[stark marsh]

theres a blender addon where you can add root bones to mixamo characters though

[plush yew]

cant you just move the nonroot animation forward? or would that cause issues?

hm maybe itd look odd cause its a constant movement

[stark marsh]

https://github.com/enziop/mixamo_converter

ok then how do i make the character stay in place

say if i didnt want root motion and just wanted them to stay still

[dawn gull]

@tidal hawk Hey, I'm using your simple gravity field plugin but when I create a new actor and add the CustomGravity and AreaFinder components it doesn't apply the gravity to the object, just the arrow. What do I need to do to get it to actually have the gravity applied to it?

[grim ore]

did you try those options I linked in that screenshot or read the docs page @stark marsh ?

[stark marsh]

oh yeah

i did that

but he still slides across the floor on one animation

i dont know if it does it on the other, it probably still does but it slightly moves in the second one so i wouldnt be able to tell

[grim ore]

ugh then you would need to fix it in blender or something else, or if these came from Mixamo (which it sounds like they did) check the in place checkbox and download them again and replace the older ones

if you name them the exact same and they are in the exact same place where you imported them from, you can go back into the animation and reimport them or right click the asset in the content browser and reimport them. it should just replace the older ones and just work

[stark marsh]

i kinda did something in blender, it messed up the animation but root motion works, he actually moves forward

but yeah i will redownload the animations

i dont see the inplace box

[torn breach]

Dose anyone know how to create a loading screen using a blueprint?

[plush yew]

There is an asset in the marketplace I bought.

[grave aspen]

https://lmgtfy.app/?q=UE4+blueprint+loading+screen

[dawn gull]

https://www.youtube.com/watch?v=lzGcVDUDU5g

[plush yew]

And I got the Blueprint and the asset is just incase

[stark marsh]

im practising my 3d modelling skills and i hope to replace everything im using eventually with my own assets mostly

im using free assets and animations to get the main gameplay down then i can replace them later

[plush yew]

Noice

[torn breach]

See I am trying to use this warp effect as the loading screen https://www.unrealengine.com/marketplace/en-US/product/warp-effect

[plush yew]

It needs to be an UI @torn breach

[torn breach]

Yeah I get that. I just can't figure out how to get that into a UI

[plush yew]

You might need to uhh

wait

[dawn gull]

you could try recording it and getting a seamless loop

[plush yew]

yeah

[dawn gull]

and then just play it as a video

[plush yew]

yeah like that.

Thats what I did to my horror game loading screen

[torn breach]

Hmm possibly

[past wing]

can someone describe me in short summary what is difference between proceduralmesh vs static mesh, if I have a gltf file can I use procedural mesh?

bit new to unreal, have used a bit of Unity before and used unity's Mesh

[plush yew]

any way to collapse a sequence in the BT so its a bit more.. manageable to look at?

[stark marsh]

i dont know the best way to add damage for hack n slash combat

[sterile tulip]

I found it @grim ore

Why do I have 2 source files

One is 9gb, one is 5gb

are these from different packs

or the same

[grim ore]

open them and find out

[sterile tulip]

Im just gonna delete these

Because it takes up so much space

I didnt even knew what these were

[stark marsh]

how should i apply damage to the enemy

i have my animations and combos set up now but i dont know the best way to actually damage

and last time i had a problem where it kept on applying damage over and over again in a very short time

[grim ore]

no best way, just the way that works for your project

[stark marsh]

maybe i coul apply damage with anim notifys

and when the sword swings open the collision

and when it ends swinging it closes the collision

[grim ore]

I can say for one of mine with combos each weapon had anim notifies that would open the combat damage window and close it, and whenever it was open if it overlapped a damagable thingy it would damage it. It would re open the damage window after it closed to prevent it from doing it more than once

so what you are saying is doable for sure

[wintry granite]

im trying to put crouching onto my game but the blendspace is showing up as empty in my animgraph

[grim ore]

?

[wintry granite]

*into

[grim ore]

oh the preview doesnt show anything?

[wintry granite]

yee

[grim ore]

have you tried to see if it's working. It's just a preview it shouldnt stop it from working.

[stark marsh]

ive sort of got it working

the melee combat

[wintry granite]

no, my crouch anims don'e work

*dont

[stark marsh]

i just need it so i can only hit an enemy once per swing

[torn breach]

@dawn gull How did you manage to add a video in?

[grim ore]

@wintry granite so when you preview and adjust the is crouched boolean to true on the right does the flow show it going thru that blendspace?

[gentle trout]

Anyone can say how can i work in ue4 with a friend??

[grim ore]

@stark marsh play animation for swing, anim notify says that damage window is open, overlap on weapon checks for overlapping something, if it overlaps something it does damage to it and sets a boolean that it did damage, anim notify in animation says damage window is closed, weapon now resets its boolean for did damage so it can do it again. Only check for doing damage when that window is open

@gentle trout look at using source control or multi user editing.

[wintry granite]

i have to re-write most of my crouching stuff real quick

brb

sorry

[grim ore]

@stark marsh some random pics from one of my projects. This is the animation montage, you can see the notifies that fire off the damge start and end portion of the animation (the swing part)

This is in the anim bp that tells the pawn (the character its on mainly) that the weapon damage window is open or closed

This is inside the character that gets told if its open or closed. what it does is tell the weapon that it's holding that it's able to damage stuff

and then inside the weapon it checks if it can damage when stuff overlaps based on that variable that was set earlier during the animation

and the weapon then tells whatever it hit that it should take damage

and repeat

[uneven hemlock]

The bottom one is

a tutorial

the top is mine

we progammed a projectile to start a particle sim when its hit

but mine doesnt work

[grim ore]

its not perfect but it's workable. It could be improved by checking for a target to damage immediately when the damage window opens instead of waiting for an overlap. it could also make sure it only ever fires once if doing that by setting another boolean like "DidDamage" that you can flip to true the first time it hits

@uneven hemlock whoah... uh... your tick... your tick is not good

your adding a new dynamic event dispatcher every frame

it should be added once like the tutorial shows in the begin play

[uneven hemlock]

holy sht im a fucing idtio

[sterile tulip]

Guys

In the tutorial when he clicks on the material, a material node editor shows up

but when I double click on the material

this comes up

[grim ore]

your double clicking on a material instance

[sterile tulip]

how do I open the node editor

so I can tile this

material

[grim ore]

open the material itself, you can see it as the Parent in that list at the bottom

[sterile tulip]

ohh thank you, so I can only do the tiling settings in the master material?

But that will also change the tiling for all other material instances

[grim ore]

the instance is basically a copy of the main material, so it has all of the settings, but its changes are unique

so if you need the main material to be able to tile then yes you have to change it, you could disable it with a switch or an if or a lerp if you wanted

[sterile tulip]

alright thank you very very much

[uneven hemlock]

white is tutorial

black is mine

im getting a weird compile error

and his is compiling fine

[spare kernel]

show me Projectile.h

[uneven hemlock]

ok

there

wait i fixed it, I was missing a include

however he didnt put an include in the tutorial

cause hes in a older verision I think

idk

[spare kernel]

remove that include

and below your includes, put class UProjectileMovementComponent;

@uneven hemlock

[uneven hemlock]

ok

btw here was the include I put

to fix it

[spare kernel]

do the same for that, class URadialForceComponent.h

[uneven hemlock]

got it

we doin some forward declerations i see

[spare kernel]

also, make sure you put UPROPERTY() above your UProjectileMovementComponent* ProjectileMovement;

[uneven hemlock]

ok

[spare kernel]

else the Garbage Collector will destroy your component

UPROPERTY(VisibleAnywhere, BlueprintReadOnly)

is what you want, show me the header once you have finished

[uneven hemlock]

I still need to include the

URadialForceComponent

otehrwise it gives me an error

even if i use the forward decleratiobn

this gives me a error

this doesnt

[spare kernel]

missed the U

its URadialForceComponent

and remove both those includes

you should have 3 includes only

@uneven hemlock

[dawn gull]

Uh, weird question. Are there any plugins that convert height maps into a float array?

[teal charm]

i started to add some asset packs into my project

Whole pack I believe

[teal charm]

🤦‍♀️

I hope folks are seeing my messages 🙂

[sterile tulip]

guys

the Unreal Engine Ocean is not working

Someone make it work

who is gonna make my water work

When I look down, the game engine is not rendering the lightning anymore on the water, so there is no light anymore which shines on the water
And thats why on the image above, you can not see any light shining on the water
The light must always shine on the water, no matter if I look up or not

the reflection of the sky is going away when I look down

how do I set so the water stays the same no matter what angle the camera is

also you can see, even on the sides all the lightning is not rendered on the water

This looks so weird

[plush yew]

Is it possible to record inputs to sequence recorder?

[velvet magnet]

I’m not sure how to fix your problem, but you should know that as of right now the water system is very pretty alpha and a lot of features are buggy and unsupported

[sterile tulip]

but in the UE4 channel they didnt have this issue

when they showed this plugin

[velvet magnet]

Did you check out the recent vid

They admitted that they faked some of the system

For the demonstration

For 2 maps they only half used the actual water plugin and then the other half was their own code to make workarounds

[sterile tulip]

POG

[velvet magnet]

As far as I know buoyancy should work and as long as you are working with a new landscape most of the water plug-in should work properly though, but for anything else it’s up to you to script workarounds and manually build things

Especially when using water with a preexisting map

[sterile tulip]

this lighting issue makes the whole plugin unusable

There must be a fix

also how do I increase the post processing box of the ocean

[velvet magnet]

Is your landscape oriented correctly

[sterile tulip]

I think so

[velvet magnet]

As in do x y and z coordinates match your camera moving left right forward backward up and down

Also what is your lighting

If you are using a directional light make sure it’s not accidentally pointing in the wrong direction

[honest vale]

that is how screen space reflections work

[sterile tulip]

does water and landmass not work together

Hey Slackers.
is it possible to run UE4 Editor on my remote linux server?

im getting some error with vulkan driver what ever

is it because server doesn't have GPU card?

[plush yew]

Might be. I had a Linux once

And before I still didnt know what unreal engine is cause I thougth it was made by EA

[burnt iron]

hmm

[plush yew]

Soo i dont know

[wary wave]

UE4 needs a GPU, so that probably is the issue

[burnt iron]

i see

that sucks i was counting my server would have some compling service for me

not even using command line?

[plush yew]

what command line? the "`" command??

[burnt iron]

no i mean from the bash

[plush yew]

oh

[burnt iron]

UE4.exe -compile -light build

for example something like that

[plush yew]

oh ok

[winged pier]

what are some general performance tips

i m currently working on an open world project

[shell compass]

Anyone know if the official UE4 content examples like ShooterGame etc can be found on Github or something anywhere? I want to know if there has been any new changes/progress and I should download the latest versions for 4.26 or if just changing my version on the ones I have for 4.22 to 4.26 is exactly the same

[wary wave]

I don't think they're in Github anywhere

[shell compass]

No, I can't find them there either :/

[wary wave]

if you want two different versions you'll have to use the launcher

[shell compass]

I just really want to know if they still add to those or if they just change the version and call it a day when a new version of ue4 comes

[wary wave]

they've probably not changed much, but I expect there may have been some changes between 4 engine revisions

[shell compass]

I think the one just called "Content Examples" is the one that regularly gets updated with new things at least

[fierce forge]

is there a way to make a landscape grass to be on a specific texture, like if i have a layer with 4 textures, each texture to have a foliage type ?

[crimson trout]

hey, how do you guys work with the groups? i mean if you have few objects like car with doors and wheels, that should be separated and animated diferently, and also you need to group it and animate with a null or locator as a whole car? how would you do this? cuz if i group it then i cant select a door or wheel separately to animate it

its just a cinematic so no need any coding or blueprint, i would prefer to avoid it cuz not familiar with it at all, but anyway if there is no other way.. well, ill have to

nevermind, figured out, so simple, just an empty actor and attach to it

[full fulcrum]

Do you need visual studios to use blueprints in unreal

[shell compass]

@full fulcrum Nope

ok, i learned,thanks~

[rancid jay]

@plush yew I see. I think i misread. Was thinking it is meant to scale more and in performnce etc.

Given that you seem to be working on bytes or something to scale even bigger. Surely you have done something smaller scale? Wondering would you ever sell your previous implementations?

[gleaming hedge]

fuccc

[rancid jay]

@plush yew just realised i wrote in the wrong channel

I happened to read your conversation somewhere and it seems you were talking about scaling more

[sterile tulip]

Hello beautiful people
You are all so nice and wonderful ☺️

[rancid jay]

@plush yew the treat 10guys as one actor was in Bp channel. Whereas the scaling byte was your conversation in CPP with glass.

@sterile tulip you too

Hello! Is it possible to display a 3d actor as an element in the UI?

[kindred viper]

yes

[loud meadow]

help

ok

[teal charm]

can someone confirm please what happens when you cancel the should you overwrite files message, that have been shared by another content that i installed. Will it cancel the installation process of the content them I'm currently installing, or just skips the shared files?

[sterile tulip]

Screenshot?

[near pine]

my camera is setup right in my pawn

but it is in the middle of the actual character

[plush yew]

@kindred viper Yes as it is possible to display a 3d actor in the UI? How?

[kindred viper]

well. You do it a couple of ways but probably the most common would be to use a render texture

I believe there was a UMG plugin for displaying meshes too. But I really can't remember where I saw it or when

[gaunt abyss]

that sounds interesting, now curious what that plugin is 😐

[plush yew]

So set up my actor off screen somewhre, point a new camera at it and render to a render texture?

[gaunt abyss]

yeah pretty much

[kindred viper]

@gaunt abyss iirc it was just the same render texture thing but placed into a widget

[gaunt abyss]

ah ok

[kindred viper]

I could probably do something with an editor plugin for such things. Perhaps add it as a native slate -> UMG widget

theres plenty of tools in the engine for snapshotting stuff in editor

[teal charm]

if you wanted screenshot from me this is what im speaking about

[kindred viper]

https://www.tomlooman.com/modelviewer/ looks like Tom looman did something cool with it

[plush yew]

does the render texture update automatically?

[gaunt abyss]

Really curious if it would be possible to have the preview mesh rendered and captured in a separate render scene/UWorld

[kindred viper]

everything is possible

[gaunt abyss]

might try that when I get some spare time

[kindred viper]

I think in the case of a seperate uworld it only has to be visible for it to matter

[modest agate]

if i set viewtarget with blend, the camera has other parameters unlike in the editor, what im doing wrong?

[thick herald]

Zombo dot com

[plush yew]

silly question - i downloaded his plugin, where do I put it?

[kindred viper]

@thick herald hahah Bill Roper said that was his favourite website

@plush yew in your project/plugins folder

[plush yew]

thnx - I'm very new to Unreal

[kindred viper]

its ok so am I. Only been doing it for 10 years and I stlil feel new :p

[sterile tulip]

I have an 8k texture in my unreal, I want to use it but its making my pc lag

how do I use this texture without the lag

[kindred viper]

ahh thats just how it is

what are your gpu specs

[sterile tulip]

Nvidia 840

2 cores 2ghz

798mhz ram

HDD

[kindred viper]

yeah thats not gonna work

2gb ram on a GPU is gonna brick at most 8K textures

[sterile tulip]

I have 12gb ram

[kindred viper]

no you have 2gb of GPU video ram

the 8k texture doesn't go into your system memory. It goes to your GPU memory

It might actually have to stream in/out of ram depending on the size of the 8K texture too.

[sterile tulip]

is t here a way to lower it from 8k inside UE4

[kindred viper]

there are ways but you should do it in photoshop or another DCC app.

[sterile tulip]

What if I make the tiling lower so its less repetition

will it then work

[kindred viper]

tiling is inconsequential

[sterile tulip]

How many autosaves of my level can the engine have at once

[stark marsh]

ok so i've got the attacking and damage working

but it works with just a hitbox attached to my character

so it only works with one weapon

how would i get it to work with multiple weapons that aren't always a part of the player

u have the hitbox be turned on with the animation blueprint

this hitbox on my character

but it will only work with this one hitbox and i need it to be able to work with many differant weapons

maybe i could have a weapon manager script that holds all the weapons

[winged pier]

Yeah make a base script for your weapons and make your weapons child's of that

[stark marsh]

but then how would i reference it within the players anim bp

[plush yew]

these are pretty basic concepts you can find in like 100+ tutorials on youtube tbh

[stark marsh]

right now the weapon is a hitbox attached to and part of my player

but i want the weapon to be a seperate object, have its own stats and to be able to turn its hitbox on in the anim bp

[sterile tulip]

Thanks I will try put this image in photoshop @kindred viper

Hello! I have several short cutscenes throughout my level. I've been trying to use just one camera and when the level seq plays, move that one camera to the correct position. I figure it's less resource intensive to just have one camera rather than one camera for each seq. Plus less stuff in the outliner to manage. Is this a good approach? The reason I ask is because sometimes my one camera wants to go back to a location from the previous seq.

thats a side effect of windows and your driver more than the engine

or the driver more specifically. But you can use a registry change to increase the value it times out with. But I'd try different drivers first.

Hello!

Anyone got tips to name and organize a huge list of GameplayTags?
I prefer to keep using config files to store them.
But I would love to find a proper naming convention and way to organize them in my project.

I personally found some hints in a GDC video where they split into "static/dynamic" if your tag doesn't change or at contrary are added/removed during runtime.
Thanks in advance!

[spare kernel]

This is kinda a game specific thing, with GameplayTag naming. You normally have your parent tag represent what it is affecting, then go down the chain, so your tag makes sense for what its purpose is. For example "Character.Status.Dead", "Character.Action.AimingDownSights" or "Ability.Weapon.Fire", "Ability.Weapon.Reload".

presented in the blueprint, spawned by cpp code, and i want to use it in a blueprint, the blueprint ist the toplevelcharacter from the examples

@plush yew #gameplay-ai

[brisk hamlet]

But for instance if you are using the GAS, you will end up with general category that you could reuse in multiple game no ?
Ability, Ability.Cooldown, Magnitude, ...

[spare kernel]

Yes, you have like GameplayCue. parent, SetByCaller. parent, etc

[calm pollen]

Hey how do i make it so whenever a coin is picked up, it plays a sound?

[grim beacon]

@modest agate Whether or not the camera is a default in the blueprint or spawned later on, you can create a public pointer to the camera (A variable that references the camera). And when you spawn this actor, you can get the camera variable from the spawned actor's reference.

You won't need to do this if the camera is a default component of the class. You can just use Get Camera

like this is my base structure for Tags

[kindred viper]

Is there a nice course/tutorial for gameplay tags you can recommend? I saw a job I wanted to apply for yesterday but I've only perused them. Need some skills with them though.

[brisk hamlet]

Neat! Because we start to have a lot of categories and I think we need a bit of organization here

[spare kernel]

@kindred viper Gameplay tags are just glorified bools

[brisk hamlet]

or enum

[kindred viper]

I get the concept, I just need some actual hands on really. So I know my way around any functionality or access etc.

best practice stuff

[brisk hamlet]

You can start by reading that

[grim beacon]

What kind of advantages does using tags have? I've never had a reason to use tags before

[kindred viper]

serendipity mostly. Finding things

[brisk hamlet]

Have a data oriented code base and not booleans everywhere

[spare kernel]

i mean there is not much to them, i would go enable them, and set up some actors with the GameplayTagAssetInterface, and do queries and stuff.

[kindred viper]

ok

@brisk hamlet ty

[brisk hamlet]

Tags are heavily used to describe a player state within the Gameplay Ability System @grim beacon
Ok I can activate this ability if my character is alive, is not interacting, is not incapicitate, ...

[spare kernel]

ActorA might have 5 different tags, if you did bools then you would have to check each bool, like Something->BlahA && Something->BlahB && !Something->BlahC, etc

with tags you can go Actor->HasAnyTags(TheseTags);

for example, or do queries.

thing is you can store these containers/queries as pre-made, etc

[steady owl]

Surely must be coming this week?

[grim beacon]

Hmm, so you don't need to have any pre created booleans

[brisk hamlet]

Yeah your character will hold a GameplayTag or a GameplayTagContainer and you can add/remove your tags at any moment

Either to describe static rules or dynamic things

But thanks Kaos!

[vale silo]

That's what I heard last week 😂

[modest agate]

thanks

[thorn topaz]

@spare kernel If I want to change game modes, I have to use OpenLevel meaning I can use PersistantLevels to have audio/UI while changing levels. Is there a way around this or a way to make the transition as smooth as possible?

[spare kernel]

you can use Seamless travel and change game modes

it is what we do going from lobby to game map

[thorn topaz]

Thanks, checking that out now.

[modest agate]

is it better to work with tags compared to references?

i got it now with the vars in blueprints, that kind of coding is still bit uncommon for me

[kindred viper]

I believe so. I guess there is a hashed lookup table for gameplay tags that makes it more efficient to find things based on if they have the tag.

[modest agate]

i will read about tags later

are you all using mainly cpp instead of bp i guess?

[floral cliff]

Got "Assertion failed: FVector::Distance(Initializer.ViewRotationMatrix.GetScaleVector(), FVector::OneVector) < (1.e-4f) [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/SceneView.cpp] [Line: 479]"

Error, on 4.26, Epic Launcher Build.

Crash randomly every 20minute, on a specific map, any idea ?

[modest agate]

do i have to select a actor in the editor and then use create a reference in the bp or is there a faster way to do this in the blueprint?

[fringe bane]

Okay so I have a theoretical question. I have a first person game. I wan't to be able to interact with an object, let's say a phone. That's simple with a line trace and an interface. Then I want to zoom the camera in on the phone. That's done with SetViewTargetWithBlend and a second camera. Now I want to show a cursor and be able to click on the buttons, but I'm still controlling the first person character. What is the best way to do this?

Okay so i am a complete noob at unreal engines blueprints and im watching unreals own learn - blueprint tutorials but i am a little lost at the enable input and get player controller.. can somebody explain this better?

need help

[grim ore]

what are you lost on?

[versed forge]

when he explains the enable input thing

and the get player controller

i don't know what he is talking about

[modest agate]

you need to enable input in the project settings

[grim ore]

definitely confused on your question tho, the point you linked to is past that and the get player controller and enable input nodes are nodes you would use... what part of that is the issue?

[plush yew]

@grim ore Is there a way to use the move to task on the BT when its outside the navmesh? Or is there a way to manually add a navmesh? Cause the tree and bush works fine (since theres a piece of navmesh inside) But the fallen trunk fails because its completely outside the navmesh

[versed forge]

it aint a issue it is just that i don't understand how it works

cus that guy didn't explain enough

@grim ore

[grim ore]

so which part? getting the player controller or enalbing input?

[versed forge]

both

im just confused

[grim ore]

@plush yew you can create and build nav meshes at runtime, but you cant use the navmesh AI nodes without the nav mesh

[versed forge]

like can somebody explain better

[modest agate]

blueprints are really cool, im kinda surprised how comfortable it is

great to learn the api too

[grim ore]

@versed forge you might need to clarify the question but uh.... There is an item called the player controller that represents the player controller or what is controlling your character in the game and the get player controller node gets a reference to it

[versed forge]

oh

[grim ore]

enable input just tells that player controller if it should be listening to input or not

[plush yew]

i know, just the move to fails because its outside the navmesh, When I turn off can affect navmesh my ai walks into it, turning it on and it cant move to it 😦

[versed forge]

but the input thing thoe

[astral sundial]

So i have this major optimization issue and i am not sure where to ask this but here. So for context i am making a tower defense game with 20 waves of ai enemies spawning. So for the waves 10-12 I get 100 fps with everything running smooth. however after that the fps gradualy drops to a point were the last 5 waves i get 15 fps with some major 1-2 sec lag hitches here and there. I thought this may be a too many actor issue as of course it is supposed to get harder, however after all the enemies are dead the fps is stuck at 15. I checked stat game to see the cpu usage it is maxing on everything saying tick (obviousely not good). To see what is causing it in the final waves, i started the match and only spawned the final 5 waves skipping the first 15 (again thinking its cause of increase actor count). But i ended up getting 100 fps and maybe dropping to 70-80 fps when a lot is happening to my suprise. So It almost seems like it starts to lag after half an hour of gameplay (but i dont think that would be an issue, let me know if that is actualy something). My next thought is it could be the spawner running its chain of code to long. It is very simple blueprint that spawns enemy then delays and continues that pattern to the end of the wave where another longer delay happens. Is this causeing the issue? and how could i fix this? maybe have two spawner actors that split the wave counts in half to "lighten the load". Let me know if you have any idea what the issue is and how i might fix it! Also is there a way to check and see what actor is causing the large cpu draw and maybe what blueprints are causing it?

[plush yew]

its either, walks into everything like a dumbass, or dont walk at all lol

[grim ore]

@plush yew it sounds like for an item like that, unless you need them to path around it all the time, it shouldnt effect it

[regal marsh]

Periodically, my UnrealEd runs into deadlock at this line.

[versed forge]

like why can the light turn on by just calling the input thing. Like why do the f to toggle light work

[grim ore]

the other alternative is you make the collision part of that tree smaller so they can get to it

@versed forge that code will not turn the light on or off by using the enable input node, if you ran that code it would not do that

[versed forge]

it does

[molten tusk]

anyone signed up for the WN Dev Contest for Unreal engine developers?

[plush yew]

hm let me try

[grim ore]

well it doesnt, the toggle visibility does

[versed forge]

oh

[plush yew]

wait can you make the navmesh have more resolution? Or should I just make everything bigger?

[versed forge]

yes but why does it just work when im in the overlap

[grim ore]

follow the code is why

[versed forge]

yes but what is calling the f

[grim ore]

what happens when you walk into the overlap, what does the code say it does

[versed forge]

the f to toggle works

[grim ore]

@plush yew try making the collision for the tree trunk smaller so they can get closer to it and navigate to it

[versed forge]

but when im outside the f to toggle does not work

[grim ore]

yes the overlap says "hey let me listen for input on this item when I overlap it" or "hey stop listening for input when I leave this overlap" and the F key says "hey toggle the light"

[gaunt abyss]

because the input gets enabled only when in the overlap area

[grim ore]

put them together and.... magic

[gaunt abyss]

disconnect those and it will work from anywhere

if that's what you want

[versed forge]

yes but the question was: what is input and how does it work

[plush yew]

@grim ore thats not the problem, The issue is that the navmesh it takes away around the treetrunk makes it so its not inside the navmesh at all, While the bush and tree still got a small sqaure of it

[grim ore]

@astral sundial are you spawning and DESTROYING actors or spawning and REUSING actors?

[versed forge]

yes but the question was: what is input and how does it work
why does it call the f

[grim ore]

the F is your key on the keyboard.....

nothing calls that, you call that when you press it

[versed forge]

omg i know

[grim ore]

input is input.. its input

[versed forge]

but how does it work

[grim ore]

game pad, mouse, keyboard, touch screen

[grim ore]

how does IT work is not a good question

[versed forge]

okey

[plush yew]

the big one works, the small one doesnt cause of the silly navmesh

[versed forge]

well don't worry about it

[grim ore]

@plush yew is it supposed to go over it or whats the issue?

[plush yew]

the move to task fails cause theyr not inside the navmesh

i can turn it off, but then my AI walks into it

[grim ore]

the move to is trying to move them to the middle of the item yes?

[plush yew]

I guess so

I just get the location

[grim ore]

yep which is the middle for this item. You could for example make the pivot or origin on your tree trunk the bottom of it and it would try and move to the bottom which would not be an issue

or make the collision on it smaller so the nav mesh covers more of it (under it to be exact) and it could get closer to that middle point

or if this is something that should not block the player, dont let it block it. is it supposed to be blocking player movement?

[plush yew]

Its so the AI moves around it

[grim ore]

ok so you want it to block the movement then? its an obstacle

[plush yew]

yes

[grim ore]

but you also want the ai to be able to move to it to collect it?

[plush yew]

exactly

[grim ore]

then you need to figure out a compromise for something that big. Move its move to point somewhere the AI can get to like the side of it or the end of it, or make the collision smaller so the AI can get closer to it. the grey area would be closer to the object and it would have more green around it so the AI could reach the middle.

I would say making the origin of the item one of the sides or the bottom for example may be the better choice

[astral sundial]

@grim ore spawning and destroying actors

[plush yew]

Hm I see what you mean, I think thatll work.

[grim ore]

if you just want an easy way to do it, the scene root component in your blueprint (the parent/top item in it) would be the location and then just put the mesh as a child and offset it so the root/parent/scene component is on the point/edge

@astral sundial that would cause it, garbage collection and memory leak. Look into using Pooling (creating say 15 actors then re using them instead of destroying them)

[modest agate]

are tiles for levels a bad solution?

[grim ore]

like tiles when building say a dungeon or room? not if you use them correctly (lighting is an issue)

[plush yew]

@grim ore I broke the vector and added 200 to the Y axis and that did the trick 😄

[modest agate]

ok thanks, yes like for rooms

[plush yew]

Atleast I know whats the issue now and I can work around it for awhile

thanks mathew!
