[normal burrow]

That’s up there

[crude linden]

anyone around who might be a wizard with Hit Event and On Component Hit events? Trying to figure out why I can't trigger a hit event for a component unless that component is the root component

As with almost every other google search result I can find, overlap events work fine, hit events do not

[plush plinth]

guys the event abort ai wont work

i have been trying to fix it for a really long time

[sly coyote]

looks like you might have things happening out of order

notice the little numbered circles to the right of each node

thats the order those events will fire

top down left to right

[plush plinth]

everything seems to be in order

[fallen wing]

Please help guys. It's really stressing me out. It never did this before until I tried to download a new version. When ever I try to make a new project it says "Video driver crashed and was reset! Make sure your video drivers are up to date. Exiting...".

[sly coyote]

🙂 the first picture and the second one are different

[plush plinth]

what?

they are the same

[sly coyote]

no, theyre not

[plush plinth]

why?

[sly coyote]

the little circle number on the right side of each node determines the order that node fires

top piture has shoot as node 0

and bottom has node as 4

[plush plinth]

oh then

anyways it didnt fix it

[sly coyote]

if a condition is listed at a low node priority than and action its supposed to stop, it will not stop that action

[hollow ridge]

Hey anyone know how to attach part of a ui to an actor?

[plush plinth]

add a widget scene component

[sly coyote]

using BP widget, just add it as a component to the character bp

[plush plinth]

zeth so what shall i do?

[sly coyote]

have it set the visible player before it checks

not in the same sequence

then drag down from the selector

and add a condiation after that to check if its set

then just shoot

i always give them something to go back to also...like "stand there idling"

so when the condiation stops them from attack they have something to do

[plush plinth]

set visible player before it checks?

[hollow ridge]

@plush plinth Youngman wdym in the actor or in a separate bp

[plush plinth]

i didnt really understand this part

[sly coyote]

set focus

[plush plinth]

first thing make a widget, then go to your character/actor then add a widget scene component

[hollow ridge]

k

[sly coyote]

ai in ue4 is tough to help with cause there is so many places where things can get screwed up outside of the behavior tree

like are you setting the seeplayer in the blackboard on the enemys bp on sensing component event for player seen?

[plush yew]

hello guys I did changing the name function and all work but I want to set max lengh of the name-how to do it?

[plush plinth]

only the event wont work

[sly coyote]

@plush yew this?

[plush plinth]

the event abort wont work

when ever i kill the enemy it aborts at that moment

[sly coyote]

your trying to do like breaking line of sight and they stop?

[plush plinth]

yes

[sly coyote]

you remembering to set the seen player to "none" after line of sight is broken?

[brittle gulch]

Hi guys, if I create a data table for all of my objects, let's say a few hundreds. in the struct of this data table, I reference a static mesh. Will all these hundreds of static meshes be loaded if I reference the data table somewhere?

[sly coyote]

no, it will only ref the one you pulled from the struct

[brittle gulch]

okay good. So I don't need to use soft references and async loading for the static meshes?

[sly coyote]

that depends on your own levels

[plush plinth]

ok i fixed my problem

thanks zeth

[plush yew]

maybe yeah, which of the 3 buttons I need to look at? @sly coyote

[sly coyote]

doing refs with tables and struct act more like the guy you ask for directions

you ask it where to find the file, it points to the folder

or file

its not actually storing a live copy of it

the branches, where i check how long the entered text is

[brittle gulch]

Okay, I wasn't sure when I read about references on the UE4 doc :

[sly coyote]

in my game its 14 characters for a name

no bigger, otherwise i set it to a substring of the entered text first 14 characters and dont allow them to enter more characters

[plush yew]

ok

[sly coyote]

yeah @brittle gulch doing the way youre doing is pretty similar to using B, but again weather you need the soft refs is dependent on your game

[plush yew]

I mean which button to look from your picture

1, 2 or 3?

[sly coyote]

the whole thing

the events are pretty self describing there...first row adds the widget, guess you can skip that

but the second accepts the new name when you click done, and the bottom is what checks lengths and keeps them at 14(for my example)

notice row 2 also has a check to not allow them to have no name...it defaults them to "Nameless" if they entered nothing and click done

you can handle that any way you choose tho

thats just what i did

[plush yew]

ok

I have this

so I need to make the code for the confirm button

[sly coyote]

yeah your confirm would be my "accept"

[plush yew]

what is this set active widget?

[sly coyote]

i have my name editing done inside a costume creation widget i wrote

[brittle gulch]

I'm new to the whole concept of soft referencing. To me it seems like a good tradeoff for every referencing, as it's not loading the asset in memory along with what is referencing it, but just when it's needed. And it only keeps the path stored.
But I'm pretty sure It's not a tradeoff for everything, I'd like to understand a bit better about it, and mostly, when to use it? In what case?

[sly coyote]

personally i dont mess with storing soft refs at all...as what i would use it on would have already been spawned in the level (weapon laying on ground)

I let the engine handle it

[plush yew]

I can't find the node fr lenght

[sly coyote]

drag off the text

and type LEN

[plush yew]

this is my code

[sly coyote]

uncheck the context sensitive

its under string len

[plush yew]

a, I did it?

[sly coyote]

yeah that gives you the number of characters in that text

which gets updated as you enter it if you do it off event text changed

[plush yew]

ok

[sly coyote]

if the name is too short just close the name edit widget?

[brittle gulch]

thanks Zeth, I think I'll forget about it for now x)

[plush yew]

have no idea hwo to do it, lol

also now when I entered 4-5 chars and it writes again that the name is short-wtf

idk why

[sly coyote]

dont worry about it too much unless you are struggling to recover performance...the engine handles most of the mem management pretty well without having to intervene too much

show me the whole thing

[plush yew]

me?

[sly coyote]

yeah

[plush yew]

what to show you?

[sly coyote]

you need to be setting the "entered name" off of "text changed" event of that editible text box

that graph is what i wanted to see

[plush yew]

this I have

[sly coyote]

off the false node in the bottom row

connect the set entered name node

and drag the text over to it from the len comparison

off the true in bottom row just set entered text to itself

or leave it empty

you want to do that substring too

btw

how i had in the example i showed you from my code

that sets it to the first part up to your limit, even if the person is smashing all the keys

[plush yew]

I did this

[sly coyote]

yup that should work

[plush yew]

yeah but not

xD

[sly coyote]

the false in second row

you need to set the name to the entered text

[plush yew]

like this?

[sly coyote]

no

[plush yew]

how then?

[quiet token]

how can i gain access to this to add? or how do i add CPF_SimpleDisplay ?

[sly coyote]

use the a node like where you set "the names too short"

your are leaving at this point, so set your characters name to the entered text and then from that remove from parent

[plush yew]

the first sentence I didn't get it

I need to put the node for name too short on false?

[sly coyote]

i tried rephasing what i said earlier....you need to set the name to the entered text

[plush yew]

english is not my native language and it is hard sometimes, sorry

[sly coyote]

you set the name....

to entered text

[plush yew]

this?

[sly coyote]

you need that off the "false"

then off the true you need to set the name to "too short name"

[plush yew]

this I need it on the false part?

[sly coyote]

yeah

[plush yew]

ok

[sly coyote]

that goes on false

[plush yew]

phew

finally

[sly coyote]

then on true its "name too short"

[plush yew]

ok

[unkempt raft]

yo why is it when i choose cpp it says like something missing but when i choose blueprints it works

[sly coyote]

you do not need to remove from parent on the true

[plush yew]

now this?

[sly coyote]

just tell the player "name too short"

yup

like that

[plush yew]

ok

and now test?

[sly coyote]

yup

[plush yew]

ok

[sly coyote]

@unkempt raft do you have VS 2019 installed?

[unkempt raft]

yea

https://gyazo.com/5b73b75e774680bbce6fb816e57e5b35

[plush yew]

yeah it works, but when I write more than 10 it saves it-lol

[sly coyote]

in the editor i think theres a place you can set a code editor

maybe that got reset somehow

[unkempt raft]

this the error

the only place i seen sdk thing is in visual studio when choosing the components

[sly coyote]

does your VS 2019 have the game devolopment tools installed?

[unkempt raft]

yuh

uh but lemme check again tho

but i clicked everything having to do with c__

c++*

[sly coyote]

it will be something like "tools for game devolopement" in the VS packages

[unkempt raft]

ight lemme check

[inner cloak]

Hi guys, any of you know of a way to make some kind of fog of war on a minimap only ? what i mean is, i dont want the fog to hide the ground content when i roam the map but only what i see in the minimap should be hidden (fog) at first and then as a move around, the fog around where the player is gets dissipated. Hoping i explain properly here.

[unkempt raft]

zeth

this

ion see anything called too for game developement

tools*

[sly coyote]

https://www.youtube.com/watch?v=0yk2JYonW8M @inner cloak

[unkempt raft]

ight then yea it is

[inner cloak]

it has to be only the world map that gets discovered, the goal is to know where i did not go

[hollow ridge]

Hey could someone help me? I have a variable in an actor, and in my level I have multiple of those actors, but the variable is shared between them. (It is not public)

[unkempt raft]

its been

[hollow ridge]

Like the value on them is llinked

[sly coyote]

check in engine settings under "toolchain"

[plush yew]

yeah it works, but when I write more than 10 it saves it-lol

[unkempt raft]

alr

[sly coyote]

screen the graph

[unkempt raft]

engine settings? where i find tha

[sly coyote]

in the ue4 engine

[hollow ridge]

could someone help me? I have a variable in a actor and I need it to be a separate value for each instance of the actor in the level.

[inner cloak]

Thanks a lot @sly coyote

had not realized at first that it was a tutorial 🙂

[sly coyote]

yeet, you would set that on the actual object dragged out in the level

[hollow ridge]

where tho

[sly coyote]

under the defaults for that actor

[hollow ridge]

no what is happening is when the variable changes both instances change

[unkempt raft]

zeth... there is no settings options in the start

[sly coyote]

its per project anyways, it wouldnt be your problem

not sure what to suggest in this case

[unkempt raft]

man bruh unreal trippin on me rn

[sly coyote]

need more specific into yeet, what are you doing and what changes those variables

[hollow ridge]

It is a begiin overlap

[sly coyote]

if you have 20 characters based on "my char bp" and you changed a variable on one in the level it should not effect the others at all

[hollow ridge]

yeah ik but it is

oh wait no it is how I am displaying it

[sly coyote]

one widget connected to all?

[hollow ridge]

yeah

[sly coyote]

that would do it lol

[hollow ridge]

I think I need to create more copies of it

[sly coyote]

just have the BP spawn a widget for itself on begin play of that bp

[hollow ridge]

yeah

[sly coyote]

glad it was something dumb

[hollow ridge]

oh wait no that doesnt work cuz I need to have the ui attached to the actor

[unkempt raft]

zeth nvm i fixed it

[hollow ridge]

and when I do that it just puts it on the screen and not on the actor

[plush yew]

@sly coyote

[sly coyote]

on a side note i must go, my idea of procrastinating is coming on the discord and help others with thier issues lol not very productive procrastination

yeet add the ui widget as a component to the bp thats supposed to have it

and position it in the viewport of that bp

[hollow ridge]

?

You move around?

[sly coyote]

just making blind suggestions, i have very little info on what exactly is being displayed, what its being used for, or what its supposed to do

[hollow ridge]

it is just displaying a number that counts down and then when you are inside of it it counts up

[sly coyote]

then that can be a component inside the bp thats using it

like a HP bar on an enemy

i assume

[hollow ridge]

how do I do that?

I am sort of new

[sly coyote]

go into the bp thats using it

and click the add component

then search for the widget counter thing

add it

[hollow ridge]

um yeah thats what I was doing before that didnt wokr

work

[sly coyote]

cause they need to spawn thier own

in the bps begin play

[swift spindle]

Hello all!.... looking for some help troubleshooting PIE hitching / freezing issues (not hardware spec problems) !!!!

[sly coyote]

and set the widget ref in that bp to be the new one you spawned for it

https://www.youtube.com/watch?v=afQdY7enoXw

exactly like this

[hollow ridge]

do u mean like this?

[sly coyote]

but instead of hp bars youre attaching your counter widget

[hollow ridge]

ok

[sly coyote]

just skip past the part where he makes the hp bar

and go to where hes actually adding it to the enemy

although it wouldnt hurt to just watch the whole thing

[hollow ridge]

that is exactly what I did, but when I had multiple of the same bp they had the same number above their head

and I checked the values are different

[glacial pecan]

anyone recognize this? I think Unreal is blocked in the firewall, but I don't even use any online features, yet this causes performance spikes every 2 seconds

[harsh tiger]

im packaging my game and this keeps popping up. does anyone know a fix?

[alpine furnace]

hey guys, is there a set command you can use to modify individual components of an array at runtime?

something like:

set class array[1] value

[misty owl]

Can anyone recommend a projectile tutorial? I want to implement a synergy system like Binding of Isaac has.

[alpine furnace]

@plush yew looking for the syntax that assigns it to a specific element

cause as of right now it just overrides the first element

[mortal quarry]

Need help, I have a Cine Camera that is animated in a Sequence - It animates and renders perfectly till frame 590 and then jumps to 0,0,0 and renders the remainder from there, even though the camera is animated further.

What have I done wrong ? (#beginner)

In my sequence, the camera does what it should when I playback

when i say the remainder, I mean every frame is at 0,0,0

nvm, figured it out

Camera Cuts wasnt all the way

[honest vale]

is it possible to take a screenshot of what a camera actor sees?

in editor

[mortal quarry]

@honest vale thanks for the reply, I managed to figure it out 🙂

[hollow ridge]

jonimake r u using C++ for bp's I saw there was just a simple block for it that you could use I forgot what it was called tho

[plush yew]

epic launcher not available, anyone else?

[hollow ridge]

um you dont need wifi for ue4

[mortal quarry]

@honest vale I think if you right click the camera, add it to a new sequence, you should be able to render a screenshot

[empty plank]

Hello people, is there a way to write a decal texture to achieve the desired goal?

[abstract relic]

Yeah, flip uv based on world normals

[hollow ridge]

HighTide could u help me

[empty plank]

I don't know how to do that.

[abstract relic]

Now you do 😛

[empty plank]

I'll write that down and figure it out then.

thanks @abstract relic

[normal burrow]

write it into google as well, its a pretty standard operation for whatever modeling software you're using

[hollow ridge]

Hey I need some help with a heath bar. I can get it to display above the enemies head, but when I add more enemies they all display the same heath. could someone help me

[empty plank]

@hollow ridge probably referencing the same bp var

[fair storm]

how can i make to select a random skeletal mesh on beiing play?

[hollow ridge]

yeah it is the same bp variable but 2 separate instances I have an ai enemy and multiple of them in each level

[fair storm]

i have to create a structure, put the skeletal meshes inside, and the tell to pick one of this?

can you show me how?

like this?

done

[rain glen]

I'm new to UE4 and wanted to just play around with it but after creating a project and launching it it crashes. anyone maybe wanna look at the crash report?

[opaque plover]

God I love how I can just create a Data Table and add new custom stuff from the editor. It's so easy.

[fair storm]

how can i, set a mask material, more preciselly i would like to make a sumple enemy hit, the enemy will be red when get hit, then come to default

[proper stump]

Super basic question, i've taken a 3d model, created an actor blueprint, removed collision, the static mesh in the blueprint has "Generate overlap events" checked. i've placed an object of that BP into the level, it does not generate overlap events, Event ActorBeginOverlap does not fire. what am I missing?

a box collision is required?

component in the blueprint

[azure shore]

guys is there a way to fix the slow motion physics? you know how when you use slow motion, any physics objects start rising off the ground then fly into space when you go back to normal speed

also @proper stump it might have something to do with the meshes collision itself, is it skeletal mesh? if so you might need to set up the physics asset but it might not be that

and how have you tested the overlap events?

[proper stump]

it's the 3rd person character and the box, when I add the box bp a box collision component it works, without it, it doesnt

testing with a print

[surreal hill]

Is this a place were I can ask questions about an error report in de unreal engine 4 crash reporter?

[plush yew]

Am trying to make a list of target of the actors that get inside my collision

am making a turret that shoot them

everything is set but the Target list am really confused about

If anyone can help out 😄

[hollow ridge]

Could someone help me? I need to display an enemy heath bar (which I can do) but then when I put multiple into a level they both just display 1 of their healths

[plush yew]

Am using Game Mode to spawn enemies into the world

Or i should use Game State for that>

[umbral palm]

Hi everyone, I'm working on a game with a team and we're having an issue where when the game is alt-tabbed, controls stop working and things just start breaking... epicly. Any resources or tips on why this may be happening?

[coral spire]

Building a couple of workstations. Anyone know if UE4 benefits in any meaningful way from having NVMEs vs SATA SSDs?

[umbral palm]

NVMe is faster because it's right on the mobo, but realistically, no unless you need the extra space for more hard drives in a small form factor case

[coral spire]

Cheers, saves me some money

[normal burrow]

hardware talk goes to lounge

[umbral palm]

Is there a better place to ask my question?

[normal burrow]

what version mold?

[umbral palm]

4.19.2

[normal burrow]

😬 yeah i can't recall issues from back then but may want to check release logs since to see if it wasn't something already addressed

[rain glen]

can anyone maybe look at this crash log?

happaned when trying to launch project

fresh project aswell

[umbral palm]

It will take me a while to read through everything in the release notes, but so far I am not finding any indication that it's an issue specific to 4.19.2...

[plush yew]

i don't understand how i cannot just remove duplicates from an array, it just removes too many without making any sense

everything works great, but for some reason this simple task i cannot do, i just dont get it anymore

anyone got an example that just works?

[hollow ridge]

Hey, anyone know if it is possible to disable inputs, but still have some pressable buttons

[normal burrow]

you could use a set onemoreed

[exotic cave]

@umbral palm : Sadly, UE's support for lost-focus issues isn't very good, however there is a (kind of poorly documented) event you can try to catch and respond to

[hollow ridge]

@normal burrow ?

[exotic cave]

Though it seems from what I'm reading that a custom C++ file checking whether or not the window is currently the focus works better: https://answers.unrealengine.com/questions/301649/how-to-tell-when-application-has-lost-focus-ie-alt.html

[plush yew]

@normal burrow in what way? i need to remove elements not set them

[hollow ridge]

oh nvm @normal burrow I thought onemoreed was like a bp or something

[normal burrow]

nah its a different collection type

all good

there are arrays, maps, and sets. sets are the ones that can only contain one of any unique item

[exotic cave]

     if (!LocPlayer->ViewportClient->Viewport || !LocPlayer->ViewportClient->Viewport->IsForegroundWindow())
     {
         // viewport is either not present or not in the foreground.
     }```

That snippet seems to be able to check if an app has lost focus, @umbral palm. You could set a flag there, then check the opposite, and at least then be given an entry point in which you could try to call some reinitializations of your engine components.

Will require some C++ deep diving, though. Definitely seems like UE could stand to implement a more robust loss-of-focus framework as I'm reading about many other bugs people have had through losing window focus.

[umbral palm]

Thanks. We'll try it!

Are you able to access the C++ code while using Blueprint?

[plush yew]

@normal burrow its hard to explain but i dont just want to make them unique, i want to detect duplicates, and then do something (remove items with the same index from multiple arrays)

[normal burrow]

k

so a hacky thing to do

use your array

and then add one by one to a set

[exotic cave]

https://docs.unrealengine.com/en-US/Gameplay/ClassCreation/CodeAndBlueprints/index.html

[normal burrow]

when your add to the set fails per element

it's a duplicate, of an element you already put in it

[hollow ridge]

how can I disable movement without disabling all inputs

[exotic cave]

https://www.youtube.com/watch?v=STZxs-NYl7w

[plush yew]

@normal burrow but why don't 2 nested loops work for this? (reverse and normal foreach give same results)

[umbral palm]

thanks! Our main developer is only using blueprints because they dont know C++, but I actually know a bit. So we'll have to work togehter.

[plush yew]

even if i save the indexes into an array, then use that array to remove the elements it just won't work lol

[worthy rock]

anim bp vs anim montage, when would i use one over the other? seems that anim bp is for movement and anim montage is for special actions. Like if I want to do a stealth kill takedown, I'd use a montage?
and actually would a stealth kill be an anim montage or a sequence?

[bitter iris]

if anyones good with physics stuff please help this unfixable with my knowledge 😦 #legacy-physics

anyone doing ludum dare?

Is that what kids are calling game jams these days? 😜

[empty cliff]

Hi guys, very stupid question but... I've a value that goes from 0 to 360, and I want to assign it to the yaw of a Rotator, but the value either get stuck in 90 degrees or so, it doesn't look to work

[umbral palm]

nvm i was talking out my butt

[plush yew]

How i can tell where the debug coming from?

its printing hello form somehwere ;d

i forgot where it is

[grim ore]

if its a print string node use the blueprint search to look for print string nodes, otherwise the output log has the calling BP

[plush yew]

MathewW am making A single player using game mode / Game State etc.. is it a must to make it clean?

[grim ore]

clean?

[calm bolt]

I'm new here, where should I go looking for help?

[prime vigil]

Hey guys, question on Mesh Import process with LOD Groups from Blender 2.81. I'm trying to simplify process using single FBX file, but UE4 just imports all of them separately. I have "Import Mesh LOD's" setting on, and here is my naming convention in the blender file, from tutorials I've seen it is correct, and yet UE4 never auto-assigns LOD's. What am I doing wrong?
Should I export all meshes separately and manually assign all LOD meshes?

[grim ore]

anywhere that seems correct, this is the catch all channel

[calm bolt]

thanks, I'm trying to work with the paint tool in landscaping and when I try and make a weight-blended layer for a texture my engine freezes, I have no idea what could be causing this or what to do. It isn't a particular texture/material it's anything I try.

[grim ore]

so when working in the material or painting?

[calm bolt]

so in the paint section of landscaping if I go down to my layers I am trying to make them a weight blended layer but when i do so the engine completely stops

[grim ore]

weird. have you tried it with a material that has no layers?

i mean thats sorta normal, it has to compile and make the layer

so if your machine is low powered or your material is complex it might freeze for a bit

[calm bolt]

yeah my rig is pretty good and it will freeze for over an hour

[grim ore]

yeah it shouldnt which is why I was suggesting to try a normal non layered material to see if its the material or the engine

[calm bolt]

yeah i've used other materials and its not a problem until i try to make one of the layers a weight blended layer

[grim ore]

and is this with just the simplest test? 2 textures samples one layer blend node and plugged into the base color? no other changes

but no it shouldnt pause for but a few seconds if that if you are clicking the + to add a layer in your landscap

[calm bolt]

yeah thats exactly what i'm doing and it doesn't freeze like this for anything else, is there anyway to do it manually without using the + button

[plush yew]

MathewW can you tell me what do you use Game Mode for?

As you check out TWOODY ;d

[grim ore]

setting the defaults

not that I know of, the + is what lets you create the layers then the layer info assets

is this even with the basicest of test materials? 2 textures, 1 layer, no changes

[calm bolt]

yes no matter what I use it still does it

[grim ore]

what size terrain? and is this in .24?

[calm bolt]

terrain is 256x256 and yes

[grim ore]

does it even pop up and ask you to save the layer info?

I can say on mine I just tested and it paused for ~3 seconds when I saved the layer info, then it popped up with about 1k shaders to compile. This was when adding my first weight blended layer

[calm bolt]

it does pop up for the save and freezes after

[grim ore]

yep freezes here as well but only for about 3 seconds while it creates it and starts the shader compile

[calm bolt]

when i look in my task manager it shows numerous shader compiles running but it shouldnt take as long as it does

[grim ore]

oh it should depending on your machine, so you see it compiling?

[calm bolt]

it doesnt show as compiling in the engine i can just see in my task manager

[grim ore]

yep thats what I mean. if you see shader compilers running and its using ~90% of your cpu or more just have to let it go

[calm bolt]

even for over an hour

on an i9-9900k?

[grim ore]

depending on whats in your project possibly. Try it on a new project, new level, just make the material using 2 generic textures in the engine and then do the landscape stuff in the new level. eliminate your project

you dont happen to have visual studio installed do you?

[calm bolt]

no i don't

[grim ore]

yep then eliminate your project as an issue. yes it could take that long if it has to recompile all shaders in the engine, it's something .24 and later does and I have heard reports of 50k+ depending on the project which is why I suggested a new test one. I did that, third person template, and ~3s delay and then 1k compiles in engine

[calm bolt]

I see, i tested on a smaller project and it worked fine, must just have to wait and hope for the best. Thanks for all your help!

[grim ore]

i dont think it helps but I beleive its an issue with .24 only

[calm bolt]

hmm so maybe try .23?

[grim ore]

if you are just messing around or learning yeah it might be more enjoyable. most people mentioned this with .24

[calm bolt]

okay thanks

[fallen wing]

Please help guys. It's really stressing me out. It never did this before until I tried to download a new version. When ever I try to make a new project it says "Video driver crashed and was reset! Make sure your video drivers are up to date. Exiting...".

(please @ me if you respond)

[grim ore]

download a new version of what?

[swift spindle]

@fallen wing update your video card drivers. Make sure your system specs are upto par... and if your techy enuf... https://docs.microsoft.com/en-us/windows-hardware/drivers/display/tdr-registry-keys

[rancid lynx]

whats the cheapest way to add a flat light of say 30 percent to an entire scene ? directional lights leave terrible differences between light and dark.

maybe 2 directional lights, at 50% power, one with shadows on and one with off ? or would that hit the cpu gpu double hard, i guess. X_x

im making a VR game, i would like a minimum darkness applied everywhere, basically.

[grim ore]

I would assume an atmospheric light would be the flat lighting you want

the sky light

but beyond that can you not just up the eye adaption/auto exposure to make it brighter by default?

[rancid lynx]

thanks. those are what i was focusing on also. ill keep checking.

what are you doin today Mathew ? are you busy? are you home relaxing ? are you working? are you at some cool secret net cafe on the beach that no one knows about, but only like 2 people there, so social distancing is ok outside ?

or are you in a cool otaku anime room full of girl pillows hacking away at some UE4 game from the future ?

im sitting in my tatami room. i just cleaned my front door. i put some cleaner on it, and it was super strong, and i was surprised , i thought the door wasnt very dirty, i thought it was a natrual steel color, but the rust water that flowed down from the cleaner shocked me, WOW my front door is white ! ? so i spent like 30 minutes cleaning to see how white. apparently i have a white front door. anyways, sorry. spam finished.

[grim ore]

you dont cast to interfaces

[half turtle]

interfaces are functions that you can implement into any object

you create an interface, and then implemenet it in the blueprint you want to have it

[plush yew]

yea

how do i do that

look up blueprint interfaces

Hello everyone, I was making my own movement code using the character controller, however above a certain speed, text spews out of the console and I'm unable to move (can still jump).

So my goal was to be able to bunny hop, and it works now, however, above a speed it locks inputs. I still have my momentum, but can't move after landing

As for what comes out of the console, turns out its unrelated

[scarlet birch]

Any suggestions on getting mesh distance field shadows working for the skeletal mesh on a character?

[swift spindle]

don't think that's a thing

what you can do is create hidden mesh pieces that don't deform and have distance fields on them

kinda like how shadow capsules work

[scarlet birch]

You can't use a shadow physics asset?

That's helpful though too. I'm trying to get shadows with a camera that's about 36,000 units away.

Either that or working shadows with an orthographic camera

[swift spindle]

ortho cams are buggy at best

[scarlet birch]

I could attach primitives I guess and have them cast shadows without being visible themselves. One of the docs implied that capsule lighting would work.

Thanks.

[swift spindle]

good luck 🙂

had to use geo last time I looked into this

I just added some spheres in the character BP, scaled them, set them to cast shadows when hidden, attached them to some bones and it's good enough for now.

Hi everyone, my level's getting heavy and I've got "STREAMING TEXTURE POOL" and some errors like this "LogD3D11RHI: Warning: Temp texture streaming buffer not large enough, needed 16777216 bytes".

I was able to solve the problem of the streaming pool via this command "r.Streaming.PoolSize" I am base at 600 and I put at 3000
But I don't know if it's right to do that.
By the way, after each launch of Unreal Engine "r.Streaming.PoolSize" recovers to 600

Or did you have another way to fix this problem?

It happens at a specific location, do I need to lower the texture resolution at that location?

[abstract relic]

Usually it means you have a lot of textures loading in that area

[candid flicker]

Yes, it is.

[scarlet birch]

I think it's set in one of the ini files. You can also just turn off texture streaming in the project settings until you're ready to set it up

[candid flicker]

Especially for gamers, Unreal tends to stop loading textures when there's too much "STREAMING TEXTURE POOL".

[abstract relic]

Setting some textures to shared will also help

Within material graph

[candid flicker]

What if I convert all the meshes into one single mesh ?

Ah 😂

[abstract relic]

I’d advise against that

[candid flicker]

All right

However, I didn't understand what you meant by the Setting some textures to shared will also help

[signal bone]

Hello

Yes

[signal bone]

im starting to tackle down a minecraft like terrain on ue4

so far i found some really useful sources on how to start this

but it seems like is quite complex

more than i thought

[honest vale]

programming is hard

[signal bone]

Well, yea i guess but im new into ue4 and never had to use C++

the drag and drop it has is outstanding

[abstract relic]

Here’s you obligatory plug. I sleep now
https://voxelplugin.com

[signal bone]

uh

i found a way to do it without paying

[ancient wave]

why dose this spot light keep casting random shadows? i changed it to static mode and the shadow wasent there so i know its this exeact lamp. the scene is made out of bsp boxes if you need to know.

[abstract relic]

Open the link

Before you shoot it down

[honest vale]

@ancient wave static lights are baked into lightmaps on the surfaces the light shines onto

[abstract relic]

Or make assumption

[signal bone]

are the pro features worth it?

[honest vale]

so you need lightmap UVs on the ground and high enough resolution on it too

[signal bone]

spawning foliage.. hm that can be done in ue4 right?

[ancient wave]

im not asking why its blocky im asking why its casting at all i have nothing there @honest vale

[honest vale]

oh right, I glanced at it and thought that was a mesh but it was a reflection capture actor 😄

Quick question, is there a way to change the way a texture looks during runtime? like can i shoot a blood particle on a mesh and it spawns a bloop on where it hit?

or actor, or anything that i can control for blood.

[sturdy apex]

@warped sun I think I have heard of decals being projected onto meshes to achieve that

[warped sun]

what if i wanted a puddle of color to go all over a mesh?

im kinda confused on how it should be set up

[sturdy apex]

Hello! I need help so that my character can crouch. At the moment, I made a crouch animation in State Machine. I have inputs from the project manager, set it in blueprint character, but I don’t understand what I need to set on the graph of events in the animation blueprint. Can you give me some advice or link on the tutorial, how I can get crouch for my character with pressing the button? Thanks!

[warped sun]

@sturdy apex das epic, ill read

[sturdy apex]

@warped sun I wish I could find something like a tutorial, but I haven't bookmarked any yet since my research hasn't gone there. I see that someone made a plugin that might save you some time, but I do not know if it will hinder performance for what you need: https://www.youtube.com/watch?v=xnAn3VSz1xs

[warped sun]

ooooOOoooo

thanks

ill look into this

[sturdy apex]

@charred stirrup https://www.youtube.com/watch?v=NJolihHJUMM this might fill in the gap for what you need and how to get them connected?

[signal minnow]

How come I swear I see some games made in ue4 that are like 25gb in size and they look the same, sameish size maps, as games that are like 3gb

[sturdy apex]

My best guess is the main usage of extra drive space would be high poly geometry, and high resolution textures/materials

[signal minnow]

I don't understand the benefit of super high poly geometry

I suppose you'd need that for things like grenades to use properly

[charred stirrup]

@sturdy apex Thanks! Looks like this is what I need. Yes, I need information on how to connect it all together.

[sturdy apex]

@charred stirrup glad I could help

@signal minnow high poly wouldn't have benefits other than looking detailed, but you can get those same details with less polys by making more use of materials that have height maps or bump maps to fake crevasses and such on the object. I've seen parallax be used in materials and it can do some cool stuff, but I think it can be expensive to use as well

[signal minnow]

Like I'm trying to download the just cause 4 on epic store's free game thing, but it's literally a 49gb game. That's gonna literally take over a day probably

Ehh I'm 1.25gb downloaded in like 45 mins

[vocal flume]

What’s your pc spec?

Can it run just cause 4 on high?

[signal minnow]

Idk, I'll get back to you in like 6 years when it's done

[vocal flume]

Because I tried the PS4 version and it looks terrible

[signal minnow]

Eh, i personally don't care much for visuals

[vocal flume]

Big fan of just cause 3 but didn’t even play past the first level in just cause 4

[signal minnow]

Prime example, my desktop's tempered glass side panel has been sitting off, leaning against my PC for like.. half a year...?

@vocal flume never played just cause, heard it was good and I mean it's free, only annoying thing for me is the download for it

Like how can the launcher not resume partially downloaded files if you turn off your computer

Can epic not manage an integrity check system? Damn 😂

[sturdy apex]

Wait, epic launcher can't resume a download after restart?

[plush yew]

define "turn off your computer" :p

[signal minnow]

Apparently not for the store games

Idk, I had 10gb, restarted PC and checked if the files were in the games folder for downloading

I saw the 10.4 GB or whatever sitting there

But the amazing launcher tells me the folder has to be empty

Steam library is far superior setup imo

You can actually manage your files

Hell, even have precache servers for your local network

[plush yew]

steam got a server in your house?!?

lol

[signal minnow]

You can basically do that with steam

[plush yew]

you can do that with squid for anything :-p

[signal minnow]

So if you have numerous people that live together that play the same game, one downloads it, caches it to the box in the process, then the next downloads it in like literally a minute

[sturdy apex]

That has been a nice feature

[signal minnow]

Idk what squid is but it'd help people with slow internet because there's nothing available

[plush yew]

squid is a cache server

[signal minnow]

Ahh

Pretty sure the steam library one was meant for like PC cafes and shit

Which have like 50 PC's

All gonna be playing csgo or whatever

So that download throttle would be hella big, even on gigabit

Pfft

[tender flume]

is it dangerous to use instanced materials too much?

i'm more concerned on the draw call

[thick herald]

What would you use instead? 🤔

[tender flume]

uhh, duplicates

so material01 then theres a duplicate again and again and again sort of.

not sure if this is efficient though

[thick herald]

no, keep to instances 🙂 That's what they are for.

[tender flume]

but wont it affect draw calls amount or performance?

[rough hound]

Would this return the "Local Player" in a multiplayer environment? Or would it just be the first player to load in?

[royal sail]

Player indexes are used in local multiplayer only

(IE, splitscreen)

In other words, yes, the local player.

[rough hound]

So if i used this in a multiplayer session it would get the player of the client it's ran on? I don't have much experience with UE4 networking and stuff but i'm working with UI and i don't want everyone to get the UI to pop up when a player clicks a button, only the local player.

For example. If i attach weapon to a springarm then pickup the springarm actor with an attach to component. Would thatt give me a soft rotation variable on the weapon?

I use attachtoComponent on meshes

[normal burrow]

great guide btw cedric, have been looking into it and thought to mention what a great resource it is

[scarlet birch]

You use a trace or collision and change the animation when it hits something or use IK.

[night bridge]

am i the only one who thinks that the "Compiling Shaders" thing is a lil satisfying

[regal mulch]

@normal burrow The network one?

[normal burrow]

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

[rancid lynx]

@scarlet birch can you give any gips about applying IK to a VR motion controller?

[scarlet birch]

If it's VR and first person I'd use a collision shape and use an animation to pull the weapon back inside the capsule collision when it intersects something.

If it's during a swing you're concerned about you have to change the animation on hit with either another animation or manually move it. You'd have to read up on IK.

[rancid lynx]

Okty ill check ik tutorials. I move my arm manually. So i dont know how to pull weapons back.

Well the vr collision boxes pass through other block actors. Also

rolling as in rolling on the floor and not slowing to a stop?

[unreal sable]

Yes.
Although it does slow down from Linear and Angular Damping a little bit, but that seems to affect air velocity as well so it's not a solution.

What i'm looking for is a tiny bounce when it hits the ground (think halo plasma grenade).

[plush yew]

Anyone have any idea on how to get webcam feed into unreal?

[grim ore]

you probably want to set up a physical material on it then to add friction and bounciness

[plush yew]

I love you

[unreal sable]

Well i tried messing with the friction on projectile component.
Anything from 1, 5, 50, 5000.
Nothing happening.

[grim ore]

thats the friction for items on that surface, your going to want to assign physical materials or change those values on the surface it colliders with

your surface your item hits controls how it reacts when it hits it

I drop a ball on ice its going to slide more than I drop a ball on sand

[unreal sable]

I added a physic material to the sphere mesh and played with friction.
Tried setting material on the surface of objects/plane too.
Still rolling : |
I'm so confused.

[plush yew]

@unreal sable try making its mass higher

[unreal sable]

I tried 100kg

[scarlet birch]

@unreal sable Just add a tiny bit of angular dampening.

[unreal sable]

Tried that too

[scarlet birch]

Then no idea. It's pretty straight forward. For the most part if you want to reduce a force you can use friction, dampening, or negate it with another force. Are you sure you're not adding a force?

Try reducing restitution too.

Set it to multiply friction values or use lowest.

[unreal sable]

Ah, maybe you're in on something.
I use "Set Physics Linear Velocity", maybe that affects it?

[scarlet birch]

I mean you're directly setting velocity when you call that.

[unreal sable]

I changed the force setting from Linear..etc to the Projectile Movement, Angular Damping seems to work now.

Or it's the mix of surface phys. material + angular damping. Not 100% sure, but at least i'm on to something.

Learning UE4 feels like:
Want to do A, something is wrong so go research B, turns out it was C you need to do A.

[scarlet birch]

It's not really a UE thing with physics though. It's the same stuff used in a lot of engines and physics is physics. It's just forces and math.

[storm burrow]

hey guys,

Any way to package with editor?

[astral phoenix]

Hello i have a problem with my navmesh when i switch level its saying ''Navnmesh needs to be rebuilt'' but i have allready done that so what causing the problem? 🙂

[gleaming lotus]

Is there any way to delete files in the project's directory in a packaged game through code? I'm using Numa's IO file writer and I'd like to give the players abilities to delete files in certain directories

[grizzled ferry]

Can anybody explain me what royality mean?

[abstract relic]

A percentage of total revenue from a product is withheld and paid to whatever is enforcing royalties

Think of it like taxes. But just as annoying

[ember notch]

Is it enough to use UE4?
8GB ram
GeForce RTX 2060
Ryzen 5 3550H (4x 2,1 GHz)

[plush yew]

Hey guys I just started unreal 10 hours ago

how do I turn this

into this

[swift spindle]

@ember notch moar ram

[ember notch]

Is the ram not enough?

[plush yew]

How do I add more transforms?

[swift spindle]

not really

[worldly dust]

I kept getting ram crashes even with 16g, you won't be able to move large files around your folder structure and other intensive tasks, after upgrading to 32G I haven't had any memory crashes

there are still some things I do in editor with my puny 4gb GPU that I need to disable my second monitor and change my resolution to 800x600 (actually reccomended by epic lol) to avoid vram crashes,

[swift spindle]

ram is very important....

[still horizon]

@plush yew right click on the pin and select split struct pin

[swift spindle]

that should be pinned

lol

[normal burrow]

pinned pin split

[grim ore]

its too bad none of that stuff is covered in any of the epic official starting tutorials or any other newbie blueprint stuff.. a shame

[normal burrow]

i avoid pin split tbh

[abstract relic]

Pin split for life

[normal burrow]

lol

[ember notch]

My problem on my current laptop is the cpu and not the ram lol

[grim ore]

my problem with my current laptop is i don't have one 😦

[ember notch]

Currently I have Intel i7 as a cpu

my problem with my current laptop is i don't have one 😦
sad

[grim ore]

should be nothing wrong with that CPU, better than most to be honest

I actually found a laptop I want to invest in just have to find it in stock at MSRP or less now

[normal burrow]

lounge be for hardware 🎵

yeah its just kind of is a suffocating topic. lounge isn't well suited for it either.

[worldly axle]

Hello, how could i separate theses bp and edit each of them separately? If i edit any of those, the other gets edited too .
https://cdn.discordapp.com/attachments/270909733580308480/701468182300459038/unknown.png

[grim ore]

you would have to either make duplicate blueprints in the browser (those are instances, they are not blueprints)

or make children version of the blueprint for each one

but uh... this all defeats the purpose of a blueprint, what did you need to edit in each of them?

[worldly axle]

i need to edit variables and somes branchs

but ok, thanks

[grim ore]

branches?

[worldly axle]

if

[grim ore]

editing variables is fine, you would make them instance editable that is the point of it.

but if you are changing the core code of the blueprint then yes you should make new unique blueprints or adjust the code to fit blueprints properly

[worldly axle]

thanks !

[sturdy apex]

Could anyone point me in the direction of how to get 3d models (panels/buttons) to align with UMG on the player camera? I would like to have a menu with meshes that can be effected by lighting in the environment. I can't seem to find any information on this

to my understanding, 3d models cannot be added to a widget

[grim ore]

correct, you would use a render texture to hold a scene capture from a camera then put that onto an image in the widget

the other option is to have your widgets in the world along with the 3d items using the widget component

[scarlet birch]

I like the second option.

if you want to use meshes for a menu then your best bet is to just setup a scene, put a camera in it and use it for your menu.

[sturdy apex]

I was hoping to have the widget for text and scroll boxes on the player camera as expected for a hud, then be able to align 3d meshes behind the text (3d panels/buttons) and if the player opens their inventory it would pop up in front of whatever they were viewing and it pauses the game. Additionally, any nearby dynamic lighting could hit the menu panels

[scarlet birch]

You could do that. It'd be easier to use widget components and attach them to the mesh's in a BP though.

[grim ore]

well you can attach widget components to your player

yep lol

[sturdy apex]

I'd imagine I could attach the meshes to the camera, but if someone were to change the screen resolution I will encounter some issues you think? Like, the meshes may start unaligning with the UMG?

[scarlet birch]

If you're going to use a scene I'd not try and align it to a hud. Just use widget components.

This is one I did. The buttons are BP that you set the text on and then set a function for them to call. https://youtu.be/UlpQG6u6iGg

[grim ore]

what you asking for is basically diegetic UI and thats going to end up having to be in the world

[sturdy apex]

diegetic UI, that's something I have not heard of before. I'll start looking into it. Thank you @scarlet birch @grim ore

[exotic lodge]

hi guys

[ancient lotus]

anyone have any idea on what the deal is with ALobbyBeaconState? is it something thats coming or what? i cannot find the class in UE4
https://docs.unrealengine.com/en-US/API/Plugins/Lobby/ALobbyBeaconState/index.html

[misty owl]

Looking at a lot of the free assets and the tutorials online, they use an older version of UE4. Should I learn on 4.19-4.22 so I can use all those assets and tutorials? Or should I learn on 4.24.3?

[scarlet birch]

There's very little that won't still be usable in 4.24 and if you're learning you might as well start with the most recent version.

[misty owl]

that makes sense. and i'll learn more by making the assets myself, too

sure wish I could use that Sci Fi Weapon pack, tho...

[scarlet birch]

You can. Just import it anyway.

Check mark show all projects and select the nearest version. Assets like that don't have anything that will break.

[misty owl]

Awesome! Thank you!

[grim ore]

IF you are super worried install the newest version it worked with then migrate it over, easy peasy

[pearl sinew]

anyone have any idea whats wrong with the texture?

[earnest pawn]

hey

is there a way to reset the project collisions settings?

[exotic cave]

@pearl sinew : Possibly no lightmap UV's? I only see 1 set of UVs (UV0) listed there. Usually when you import models for UE you allow it to autogenerate lightmap UV's it needs for static baking into UV1.

https://docs.unrealengine.com/en-US/Engine/Content/Types/StaticMeshes/AutoGeneratedLightmaps/index.html

[scarlet birch]

Preview window is dynamic lighting

[exotic cave]

It is. Just taking a wild guess.

[dusty basalt]

Hey all, I seem to be facing a roadblock in my build when I have plugins included (that I purchased from the Marketplace). https://media.discordapp.net/attachments/550441494448832532/701346682763477022/unknown.png
Anyone have any idea what's going on with the build breaking? I am not a programmer so debugging via VS is untenable for me unfortunately.

[hollow ridge]

how can I change an actor to be black and white with a bp

[exotic cave]

@hollow ridge : Have two sets of materials for that actor, and use the Blueprint to change back and forth between them

@dusty basalt : What pack is this?

[dusty basalt]

It's a UI for allow for picking files

[exotic cave]

Can I see the link on Marketplace?

You have a file there which has an error in the code.

It looks like it's missing an opening brace, which might be easy to fix.

[dusty basalt]

I did a successful build 4.23, but now it seems to break. https://unrealengine.com/marketplace/en-US/product/file-picker-ui-dialog

The same message happens when I disable that plugin and it picks up the same error on a 2nd custom marketplace plugin (about dynamic lighting emitting from media textures).

[exotic cave]

What is SAEPerth_YT_1.0.Target.cs ?

That's a C# file. Unreal Engine uses C++.

[scarlet birch]

It's a target file.

[exotic cave]

UE uses C# for build stuff?

I suppose it does!

Hmmm.

Unfortunately, @dusty basalt , it may be hard to solve this without programming skills.

[dusty basalt]

Ah crap

[exotic cave]

One or another circumstances, possibly plugins that are not updated for your version of UE or whatnot, have munched that target file, which is a file UE uses to build your project.

[dusty basalt]

Hmm, I'll do some more tests with alternative scenes in that case. See if I can get the build to go in a fresh scene with the plugin included.

[scarlet birch]

Can you try building in VS?

or regenerate the VS files.

[exotic cave]

If he deletes that particular target file, what happens?

I can't find much documentation on all this.

[scarlet birch]

It'll try and replace it with a default one is my guess. Which may or may not be fine.

I'm inclined to think it's not the issue.

[dusty basalt]

I've purged the intermediate and saved folders and tried to rebuild and no dice. I'm trying right now in a fresh template scene with the plugins enabled and used, and it's building fine....

[rich helm]

Is a source build better?

[grim ore]

yes

[normal burrow]

really?

[grave nebula]

Yeah, source builds run much faster. Moar FPS!

[normal burrow]

had no idea

[scarlet birch]

Idk, I always install source but don't build from it as much anymore.

[normal burrow]

I use launcher on oddball/testing things, but yeah not on serious stuff

[plush yew]

Anyone know how i would start a code for someone to lean like in R6S type leaning

Blueprints^^

[jagged salmon]

Hey guys

Is it possible to choose a UVMap from the fbx for the lightmap bake?

In this case I want the second UV Map to be used when building the light

[dusty basalt]

K, dunno wtf the deal is, but I migrated my project to a fresh scene and it's building fine now....🤷‍♂️ 🤦‍♂️

[scarlet birch]

does radial damage trigger anyDamage?

[pearl sinew]

@exotic cave Thanks for the reply. I don't know what fixed it but its fixed now all of a sudden. I played around with settings that have to do with lightmap UV

[scarlet birch]

nvm, I figured it out. I had a gun that had collision which was blocking the damage.

[open ermine]

are there any good example videos on people using dbuffer aka mesh decals? The documentation on it feels pretty vague it's like "yup, here's the wireframe! and then you apply a material and done"

[scarlet birch]

DoH!, I wasn't adding the actor that was exploding to the actors to ignore for radial damage and since it blocked visibility it was only damaging itself.

[plush yew]

is there a reason 'hollow' isn't exposed in brush settings for geometry sphere ?

[knotty vessel]

Not possible to make a Array from a Enum?
Any other Array works, however Enum, fails.

[barren flume]

I'm having an issue with a button for mobile users

I'm trying to get it so when they press it the character will ragdoll

I already have a blueprint for pc users

but it's not a button

you just have to press x

[sacred sluice]

Hello, everyone! I want to make a helper dog in the game. Has anyone ever seen a companion tutorial?

[bold bay]

https://www.youtube.com/watch?v=Z3mWSpKb3Kw

As a start

I dont know how much knowledge you have

@sacred sluice

[sacred sluice]

Thanks! but it is so simple)

[gaunt abyss]

@bold bay do enum EItemCategories : uint8
That's required for C++ enums to work in blueprints

[bold bay]

@gaunt abyss Thanks, ill give it a whirl!

[plush yew]

I just solved a problem in ue4 by myself and i feel like a genius

[bold bay]

@gaunt abyss It now gives an error: Missing "{" in enum

[barren flume]

shoot

i spent like an hour waiting for the game to launch on mobile

and it opens up and i get a message saying

Failed to open descriptor file ../../../MyProject/MyProject.uproject

then it closes

not sure what i did wrong

but i don't want to try again and get same error

[worn granite]

@bold bay

enum class EWhatever : uint8
{
  First,
  Second,
  Third,
};

its the same syntax as extending a base class, but without access specification

class FWhatever : public FMyBaseType
{

};```

also @bold bay, #cpp in future

[bold bay]

gotcha, thanks!

[low rock]

hi guys, does anyone knows why my movable actor is too bright?

it has to be something from here

[near crater]

how to play as imported characters which use custom armatures/animations?

[rich helm]

Where can I find the source code of UE4 in Github

[dim arch]

@proven tulip you can procedurally generate a maps layout using blueprints

if you want to procedurally generate meshes, it's more difficult

[proven tulip]

I'm a C++ developer mostly. Is is normal to add blueprints like that into a c++ project?

[dim arch]

for example, you can generate the layout of objects in realtime, but you cant generate the shape of the objects in realtime very easily

yes, its easy to expose your C++ code to blueprint

[proven tulip]

Ok, so it sounds like to me I should just fully migrate to UE4 now and save a headache.

[dim arch]

the system you use to generate the layout of each level should be easy to hook up to the object placement system

I would use blueprints over cpp to familiarize yourself with the engine framework though

just expose your code to BP, for example return and array of objects/locations and then use blueprint to spawn and place them, possibly create different materials etc

[proven tulip]

I did a tutorial today with blueprints and it was ok.

[dim arch]

its good, the only problem is if your function returns a struct of datatypes, you need to define it and build the engine before you can access it in bp

[proven tulip]

What I have is basically a map that inherits a 2d array of type std::vector<Item>. So, each cell holds a vector. After the map is generated, items are dropped into each cell. I'd have to have Unreal read all of that in somehow then.

It does sound like starting off with Blueprints might be the better idea for learning purposes...

[rich helm]

How do I download the visual studio 2017 to get source build?

[normal burrow]

Definitely want to move on to ue4 @proven tulip

Console stuff is great and you’ll be glad you have an understanding of general c++, but working with unreal involves a lot of generated code that is kind of its own thing

Also standard library stuff like vector is just not something you’ll use much

Nothing stopping you from, but it’s not compatible with the generated code side

[proven tulip]

I see. Should I be learning with a C++ project and use blueprints? Most tutorials say to make a blueprints project.

I'd like to see both going on.

[normal burrow]

Honestly would recommend understanding blueprints
