Because it's getting a bit ridiculous with memory
rocky portal
but no point in doing that now until I need to optimize
safe rose
And trying to get it on PSVR later this year
rocky portal
you using Actors too?
rocky portal
I have UOBjects
safe rose
I am literally never despawning them until they break
safe rose
But I have a full body slot system
frank escarp
@safe rose i have been using data assets and tablets, and didnt really like it
rocky portal
none ofthe Actors tick...just make them stop rendering, no collision
safe rose
Which I forgot to mention
frank escarp
they are still clunky to use
safe rose
Is why I do my system the way I do
rocky portal
my Actors really just function as Entities
frank escarp
for my next game ill just use json files that i load myself
safe rose
Beacuse other people can steal weapons off others
safe rose
I am not very well versed with JSON yet
frank escarp
becouse the steal is kind of instant and there is lag involved
it is jarring
very jarring
rocky portal
I make a "Backpack" by adding actor components: InventoryItem, ItemContainer, Equipment, ContextHandler (builds context menus and interacts between components polymorpihcally)
safe rose
Going to breeze through a few things I probably should have picked up by now over the past 3+ years
rocky portal
Player has: EquipmentHandler (Equipment equips here)
and you link the UI Widgets to the appropriate index in Equipment TArray

Is there a better way to handle timer calculation than Get Game Time In Seconds? I want to zero this out wihtout having to forever substract the difference....
rocky portal
could do it dynamically but it was easier to maintain this way
if a Level can load thousands of Actors in and run fine...it seems silly to me to try to optimize this when a player might only hold 10~ Actors in their bags in a game
those Actors would have already existed in the level and you're just pointing to their memory locations through the inventory
but if you're dealing with millions of "Items" across persistent inventorys or something, you're going to have to do it in a more optimized way (like an MMO)

Is there not a Round to Decimal Place function in Unreal? I only found this: https://wiki.unrealengine.com/Float_as_String_With_Precision
keen birch
Nope, there isn't
I usually just multiply by 10^x with x being the amount of decimal places, then round that, then divide by 10^x again
vale osprey
Why do you need it?
light thunder
Mainly for display purposes
telling fire chief's a benchmark time occured at 4.8578 seconds seems a bit too much
but I don't want to round to integer
so 4.25 is fine
I'm tryign to decimal thing now, it just seems odd to have to do this much for such a simple and relatively common operation
vale osprey
then just use ToText for display purposes

Is anyone else getting compiling shaders everytime loading up the game? It's annoying as fuck (4.18.2
safe rose
I haven't, but others are reporting the same issues
bitter iris
It's a material in the engine folder just don't know why it's having to recompile everytime
vale osprey
Maybe it’s not being saved if it’s in Engine folder
Replace it with a copy I where you are using it and place copy in a regular content folder
rocky portal
Let's say you have an Actor class "M4A1" and this Actor has a SkeletalMesh and you can attach a Foregrip, Silencer, and Scope on this M4A1...and there are many different Foregrips, Silencers, and Scopes
So my M4A1 can be entirely different from your M4A1 and I want this to be persistent
How would you represent this M4A1 in inventory and account for the swappable weapon Parts
While also using the same system to inventory simple things like "Empty Can of Coke" with just StaticMesh
And this has to also be saved for when you close the game and re-open it
safe rose
Ah neverming @bitter iris just ran into it
doesn't seem to affect all my maps though, so not sure the exact issue
but can't remember if I've been on this map since 4.18.2

Hello guys and thank you for the accept!
I have one little question. I need to do a 2d game for the uni and i made the menu and a prototype for the game, but for some reason the game won't load with open level node. If i use the standard map from ue4 it's working, but my map won't load. Do you have any idea what did ido wrong?

PSA: "Enable Details Panel Favorites" is broken in 4.18 and causes the entire Details Panel to become a horrible broken mess.
It worked before though...
gloomy apex
Hey, can I tweak when is falling is activated from a walkable surface
the thing is that i have a double jump, but since I am making a platformer, when i jump just at the edge of a platform, the character is detected as falling, so my double jump is kind of used
weary basalt
Maybe you should change your Double Jump design? Simply falling should not be the criteria for your DJ to be used up?
Pressing Jump twice should be the criteria for having used up your DJ
weary basalt
Uhh whats the difference?
gloomy apex
If I was only going for a double jump I would have used Do N
but I also have an air jump thingie
so for example the character might fall of a platform, without jumping off of it
then he can jump once
mid air
weary basalt
Ok well then your criteria only changes slightly. To perform an double jump the first initial jump must have been when the Character was touching the ground.
Otherwise you only let them jump once
gloomy apex
I also have sliding, so I dont use the Jump at all as it doesnt work when crouching is enabled, instead i have custom launch character nodes for the first and second jump
changeing this system is kind of not possible, as it would break other stuff
weary basalt
Welcome to programming.
white magnet
You should be able to override CanJump in your character to allow jumping while crouching too
But yeah, this is part of programming, learning to work with what you got.
weary basalt
Or more importantly, biting the bullet and refactoring large amounts of code to end up with an better more flexible design overall.
gloomy apex
I mean I would rather create trigger boxes on platforms and code them :d
gloomy apex
its just that my lecturer mentioned something about him being able to play around with the is falling tolerance, but I cant seem to find such thing
gloomy apex

Guys im putting together a team to create a Video Game. With Unreal Engine 4. Anyone wanna join me?
gloomy apex
essentialy when close to the edge of a platform, not to trigger is falling yet
in the picture the "air jump" activated, even though I jumped at the edge of the platfrom
i mean I did not technically
if i let people playtest the game at 120 fps on my 120hz laptop
everything is fine
but my team has 60 hz laptops and they keep compaining that during playtests people jump after platforms

white magnet
Dude just go to #looking-for-talent And actually post some details if you're actually serious about this
gloomy apex
but yeah, @safe rose basically because our game is fast paced, soemtimes playtesters jump too late, and they cant double jump because the jump is on an is falling state
left pelican
I have some good ideas
tame bluff
How would you handle collision for this giant circular wall
when I import it normally the center isn't hollow with collision and I end up having to use complex collision
left pelican
I cant post on #looking-for-talent
restive eagle
you can use complex as simple
tame bluff
Do you mind if I ask what the difference is?
floral heart
Read the pinned message in #looking-for-talent for instructions on how to use it.
restive eagle
umm i cant give a straight answer, just this method fixed some of my personal problems. but if you want to use only simple then best way would be add it via 3d sofware
as i understand complex is more detailed
not a single plane
tame bluff
Oh, okay.
left pelican
Ok
tame bluff
Currently when I spin the exterior circle of the room and it collides with the camera the player just goes through the wall
white magnet
@gloomy apex If people are jumping too late, then maybe that's a core design problem that needs to be addressed. Is the game too fast? Are platforms too short? controls too hard?
tame bluff
but when I otherwise walk around I can't go through anything
restive eagle
hmm maybe your camera and pawn has different collision settings
tame bluff
It's probably because I'm just rotating the object not applying any physics impulses or physics correction
floral heart
It spins!?!
tame bluff
yeah haha
Currently, however, I'm just testing
Final level design wont just spin on its own
floral heart
Could be character movement component is trash. You could get away with not spinning the wall's collision, if the doors don't need to be open. Spin only the floor's collision, no one will notice.
plush yew
yeah what the fuck people put shit on market place that doesnt have documentation or any fucking tutorial
Like what?
floral heart
@plush yew Google "caveat emptor".
restive eagle
@tame bluff also give it a read about convex, you can set accuracy for the collision. might help but not rlly sure

The previous topic was me insulting the character movement component.
plush yew
What would be the ideal way to set a variable on a Pawn from the Behavior Tree? Call a function on the controller that sets the variable or just set the variable directly on the Pawn?
weary basalt
I dont read the channel every second 😃 Re reading all the garbage hurts my head sometimes.
@plush yew Direct would probably be more ideal, unless design requires it otherwise
plush yew
Okay thanks 🙂
weary basalt
If its an specialised variable to an child probably better off going through an parent or using an interface...
But that depends on how generic you want or need it to be 😃
plush yew
If I wanted it to be more modular, I'd move it to the controller right? So I can reuse Service/Task
Programming design always gets me. I don't know if a certain implementation is good until further along in a project
weary basalt
UMLs can help with that. Plan it out on paper first then you can foresee any issues with the design before you even write any code.
Even an Flow diagram
Is better than nothing
plush yew
Ah yeah I remember making UMLs when I was studying
safe rose
Never learned UML
tame bluff
I remember making a UML like 5 years ago
and that was the first time I ever actually finished something
never again though
safe rose
I know people who use UML in UE$
tame bluff
fuck im lazy
weary basalt
I dont use them ALOT but they are helpful especially when first planning an large system
safe rose
I don't know why though
weary basalt
Also great as an overview of the structure of an system as well
Doesnt have to be detailed
Just seeing what inherits what and which classes depend on others etc etc can be invaluable especially when you go to refactor the system or someone new jumps on board.
But like all documentation, it takes time and can change alot lol
There are alot of free online UML builders
I usually plan it out and then take an screenshot since most of them require an sub in order to export them lol

tame bluff
For me they have almost no down time
and they have awesome support
regardless of what their front-end looks like 😛
They are a chinese company first and foremost and culturally that is actually very similar to most chinese style sites currently
At least once or twice when I contacted support it was chinese
restive eagle
y i trust you on that, that they are responsible towards their customer, but its too international for me. will stick to my own country probably. no need to have a server in middle europe or somewhere else
my last web hosting was in hong kong, when i needed to access it from china, it was internetsolutions.hk if im correct. didnt make a good impression though
still did its job, cause getting one in china you need a license probably, which is hard to get. well nvm. thanks for the tip though. will save it if i ever need it accessed from china
tame bluff
Yeah no prob, I think I realize you're looking for a virtual remote d esktop
is that what you were meaning?
I don't think 3ix would be good for that
rocky portal
What is the typically used method of saving out and inventory to load in a new Level?
for Multiplayer
each player having their own inventory and stash outside of the gameplay levels
like... Main menu with Stash and Inventory -> load into another level with other players with your inventory
weary basalt
Generally for multiplayer, you wouldnt store the stash contents on the client at all.
It would be saved to an Database on an server somewhere and then whenever its needed would be grabbed to be displayed.
If you dont care about that and its an local coop kind of game with splitscreen or something, you can always attach or save the contents of the inventory to the GameInstance.
GameInstance is persistent throughout the life of the games actual process on the machine.
rocky portal
to a SQL database?
I thought about this solution @weary basalt and really like it (I work with SQL daily)
but I'm not sure how I would go about storing in a DB what I would need to re-create my game items
as they are fairly complex
weary basalt
UObject has the ability to be Serialised
weary basalt
Serialising converts the object into an byte array which you would then store onto the database
To rebuild it you just deserialise the information
Or you can go an different way.
rocky portal
oh that's cool
weary basalt
Create entries for all items on your database and just store an tally of them for each Player
rocky portal
well all of my items can potentially hold other items
like a backpack holds items
a gun holds gun parts
a gun part (like a rail) might hold another gun part
a magazine holds ammo
weary basalt
Im not super familiar with Databases so im sure you could work out something more flexible.
rocky portal
I could use a SQL database to store these relationships
by storing some ParentItemID and OwnedItemID
but difficult part is going from these database attributes back to the correct class in UE4
which I could probably use a DataTable for
to relate a String like "AK47" to a Class property for AK47
wild kestrel
binery is not quite good to work with in database :p
rocky portal
and each item needs a unique ID, item type (like above AK47) to find the class property value, and any values that might be unique to that object/actor instance
like Durability
i mean..does that sound like a logical design?
since you cant store directly a Class Property in a SQL table
wild kestrel
Actully you could :> You can read property structure of class
from that you can create database structure
rocky portal
wait what?
so in C++ it would be TSubclassOf<AActor> ClassName
and then in Editor you could set that to BP_AK47
wild kestrel
i write anwser on anwserhub explaing that
rocky portal
and SpawnActor From Class using ClassName
so if I could directly store that "ClassName" in relation to the thing in inventory
I could easily re-build my items, and it should be pretty light weight
wild kestrel
you knwo asset system is already kind of like data base
there table property editor
which you can edit like database table
it not as flecable as SQL but still nice :p
wild kestrel
no
you pick bluepritn asset
and edit properties of multiplke blueprints like a table
in general practice in UE4 each item should have a class and all properties should be set in defaults
rocky portal
Yeah I get that part
wild kestrel
thats how it was ever since UE1
rocky portal
I have unique classes that will have Defaults
but where they can differ
a Pistol could have 4 different parts
dynamic
so 3 people could have same pistol
but one pistol might have a threaded barrel and suppressor
one person might have same pistol with wooden handle
wild kestrel
Then make a addon system? :>
rocky portal
it's easy to make the system from a gameplay perspective
wild kestrel
oh you mean weapon madeo ut of parts?
rocky portal
it's more difficult when you talk about serializing these things so they can be passed to a new level
yes Shadow
the easiest way to think about it is that any ItemClass can hold other items as if it has its own inventory
wild kestrel
to new level? You knwo about level streaming?
rocky portal
if it is setup as such
this would be MP also
so like 6 clients take gear from their own stashes
into 1 instanced level
I know in theory how I could store all of this in a SQL db
or if there is a UE4 way of doing this
wild kestrel
either way about table right click asset and open Asset Actions and Bulk edit :>
rocky portal
im talking about runtime stuff m8
I'm on main menu...I take a modded gun from my stash and put it into my inventory
I join a game
you do the same and end up in my game
I kill you..I take your gun
weary basalt
You need some persistence on an database on an server somewhere
That is the key here
rocky portal
That's what I'm thinking...trying to sort this out in my head lol
weary basalt
Shadow is completely missing what your trying to achieve.
rocky portal
is a new area for me to investigate
I know how to setup SQL databases and normalize tables and such
wild kestrel
i dont know you guys been tlaking baout datbases so i siad :p
rocky portal
I have good idea of how I could store this in a database to recursively rebuild a players inventory
wild kestrel
again you can get property structure and save it to database structure
and then hold gun data as entry
if that what you mean
rocky portal
but I have to come up with a way to go from "SQL allowed attribute types" to UE4 Actors/Classes
what is property structure
You have to store every part on the gun and their own inventories
wild kestrel
class have oproperties right?
rocky portal
the gun "owns" the rail when it is attached
wild kestrel
and then oyu can store object in database
rocky portal
the gun is inside a backpack
the player has the backpack equipped
so you can't just "build a gun" with properties
you need to build all the parts too
wild kestrel
so?
rocky portal
so lets take the lowest level here of a Flashlight and then one level up which is the Rail that the flashlight is attached to
wild kestrel
do those part have any atributes?
rocky portal
just a list of "slots" that can take parts
and the class can define what parts are allowed
but in SQL you could have record that consists of:
Rail ItemID as parentItemID, Flashlight ItemID as childItemID
wild kestrel
do part have custom attributes or part can be declered in classes?
rocky portal
and a table that has ItemID's and what type/class they are to re-build them
parts will have defaults of course that affect weapon stats
but if you're spawning a new one from the Class, this should be fine
wild kestrel
yes but part is a class right?
wild kestrel
then you can store classes as strings
you can even some how translate them to some IDs
if oyu like
rocky portal
now we're onto something! ... i was trying to find how you would do that
I don't want to store a full asset path
wild kestrel
loon UE4 config system
rocky portal
just something I can store in a standard DB that I can translate back to a ClassName or something to build an Actor/Object
wild kestrel
try save cUClass ti ini config
rocky portal
what?
plush yew
So I've been trying to find an explanation of what Controller/PlayerController actually is and not a high level explanation. Does the Controller actually do anything code-wise if you handle the input in the Pawn?
rocky portal
not really trying to just set properties for things on load
when you "loud out" of the stash screen ur writing to a database
or even when you move something if u want to have very little client trust
when you're "loading in" to any screen, it must read from the database to basically build a new inventory
wild kestrel
what im saying is you same as ini saves data you cn make system that works with DB
rocky portal
oh this is how they did weapons back in the day
wild kestrel
that goes back to reading properties
rocky portal
i remember they had .ini files or something for Half Life 1
or maybe it was some old dino hunter game where you could mod the .ini's to change weapon behaviors
weary basalt
Hes saying you can use the INI system to generate Objects and their Properties as Strings which you can then send to an DB
wild kestrel
i would need to dive in to the code to give you anwser but im busy now :p
rocky portal
hmmm
wild kestrel
look on how config system does it
rocky portal
Ok, that's pretty cool
weary basalt
You dont actually create or modify any INIs
The INI system itself can handle converting Unreal properties to Strings
An Vector for example passed through the INI system would read MyVector=(0,0,0)
wild kestrel
Thats one way of duing this, you can take steer with GConfig
rocky portal
does it naturally store the ClassName to be used?
or would i just have to do this to some kind of Initializer Struct
oh those use USTRUCT
I will have to look more into this
rocky portal
I can use a DataTable for sure as a LookUp type thing
like a String "AK47" pulls a class property for AK47
rocky portal
SpawnActorFromClass< Get Class using DataTable >
wild kestrel
look how config stores it
rocky portal
I'm referring to Properties like
TSubclassOf<UWeapon> WeaponClass
can you store those in a DataTable
wild kestrel
they just limit class secletcion thats it
wild kestrel
try save UClass* in ini config
and see how it stores it
and look in code how it retrives it to UClass*
rocky portal
hmm this is cool
I'd have to figure out how to go from .ini to relevate database field
and then back
relevant*
wild kestrel
regardless of container of string, in some point of process its just string
rocky portal
right
so somewhere in the engine code.. UE4 defines TSubclassOf<T>
or UClass or w/e
wild kestrel
No
Again TSubClassOf = UClass*
TSubclassOf is just template
but in C++ it function the same as UClass
rocky portal
ok but going form "This is just a collection of letters"
wild kestrel
i mean it a C++ hacks with clast overload :p
rocky portal
to "This is just a collection of letters" being a valid Template arguement for a class
wild kestrel
but logicly it the same as UClass*
rocky portal
that's deep deep down there
wild kestrel
TSubclassOf us UClass* template, only diffrence is it limits class section to specific relation
but it work the same as UClass*
becuase technicly its UClass*
weary basalt
Your not getting what the INI system does. It takes in an UClass type and then outputs an String to be stored, you can feed that String back in and get out of it the UClass type again
Or any property
rocky portal
Oh that clears it up then
so it's easy then to say "This is an AK47!" -> String to DB
String from DB -> "Hey UE4 this is an AK47 make me a new one!"
weary basalt
👍

Reflection system is what makes everything seamless :p
It is what makes just "BlueprintCallable" all that need to be added to make a node
or config system just by adding "Config" to store whoel classes
if oyu master it you can make same as smart code as engine is doing
save time to make UI work for example
by generating UI based on reflection data of classes

Do decals kill performance?
south ridge
@gloomy helm Erm, it depends
It's more of a question for #graphics
But each decal renders decals pixels over existing pixels of the scene, increasing total number of pixels crunched by your videocard
So yes, they can kill performance if used excessively, though they are relatively well optimized

Why am I experiencing some random frame drop in UE4?
I moved from old (weak) PC to Gaming (current) PC and I still experience same things.
I'm creating a simple things and out of nowhere It starts to lag.
wary wave
how is anybody supposed to be able to answer that question?
wary wave
we know nothing about your hardware, or what you're running
fossil ore
Oh sorry.
wary wave
but yeah, there are profiling tools you can use
fossil ore
Current specs:
Nvidia 1060
16GB ram
i7 7400
cloud cobalt
Generally speaking, you need your entire game to step all logic & graphics in less than 17ms - that's very fast. It's very easy to break that.
Use the profiler to get a look at what's wrong
And test your game as a packaged game outside the editor
fossil ore
How does one opens Profiler :v?
cloud cobalt
First step should be to open the console, enter "stat unit" and monitor the numbers. You'll get a "game" time and a "Draw" time - first one is CPU perf, second one is GPU perf.
Depending on which one is faulty, there is a dedicated profiling tool
fossil ore
ok
cloud cobalt
Again, it's important to do this with a packaged build.
UE editor is nowhere near game performance, even on good hardware

The test map is set, the mai menu is done, everythign works except the fact that when i will set the open level node on the start button, it just won't load my level. I asked yesterday and i got an answear, i read and tried but won't work. Can anyone help? i can zip the project and send if needed. I really can't move on with the map and other good things for the game if i can't make the conexion between the menu and level. Sorry for bothering with stupid questions

is there a way to animate the scale of some grouped actors?
i basically want my grouped shapes to do that
vale osprey
does group has it's own transform?
wary wave
you want to scale the actors and retain the star shape?
vale osprey
do you have grouped actors or you have multiple static mesh components in the same actor?
royal jolt
grouped actors
i'm making a surreal environment so i want the star shape to "break" (scale up) then fix itself again (scale down)
i've never animated / used keyframes in unreal tho - i usually import from Maya
wary wave
you'll have an easier job controlling it as a single actor, I think
grim ore
@plush yew are you sure your open level command in your blueprint in the main menu is even being called?
plush yew
@grim ore yes, the node is there( i even tried with set visibility). Idk if the set visibility was a good idea but in my mind it worked, but on paper no results
rocky portal
anyone here ever setup and integrate MySQL with UE4?
grim ore
did you make sure the node was being callled? F9 breakpoint on it or a print string before it?
also the name of that map is the same as the one in your game mode which means that would do nothing
well nothing you want lol

this makes no sense. I'm getting a message "warning : Module constructors should take a ReadOnlyTargetRules argument (rather than a TargetInfo argument) and pass it to the base class constructor from 4.15 onwards. Please update the method signature."
Build.cs file referenced in the warning contains zero TargetInfo arguments.

@hazy lynx Create an empty project, look at the Build.cs syntax

The message isn't super helpful

I'm updating to 4.17
that's the issue, I already changed TargetInfo to ReadOnlyTargetRules

Hello, using the Foliage tool, is there a way to paint the same mesh with multiple materials?
(I've got different color variations of the mesh that I want to use)
wary wave
I think you'd need duplicate entries in the foliage list
How are your colour variations done?
muted minnow
Different materials. Using a pack of trees from the market place, it has leaves in green, yellow, red, blue, etc
How do you duplicate entries in the foliage list? All I can seem to figure out is I can copy the mesh entirely in the content browser, and then add two
But that seems a poor solution.
wary wave
the editor I'm using has custom tools, so unfortunately I can't refer to it, but is it not possible to create a new foliage type that references the same mesh and a different material?
I would personally take a look at those materials, and see how the colour variations are handled
for the sake of optimisation, you could potentially merge those materials into a single one, and use a single foliage entry?
and use something like PerInstanceRandom or ObjectWorldPosition to decide which variation you should be using
muted minnow
FoiliageType only has mesh, no material settings.
There is a FoliageInstancedStaticMeshComponent... that's interesting, I wonder if there's something that can be extended there.
nova heath
Is it possible to have a HUD draw a decal at the mouse cursor?
I've implemented the blueprint code that was working on the actor but it seems the Decal component just isn't being rendered.

@royal jolt You could child/attach your objects to an invisible dummy object and scale the dummy object.
Or build it in a class blueprint / actor and scale the blueprint root - even better.

Anyone here a mod of the unreal engine subreddit?
I need some help
someone stole my game and uploaded it there
nova heath
Anyone have an idea how to keep an object from colliding with itself?
If I allow it to collide with WorldDynamic (which it needs to do to be placed on other moveable objects) then when I go to place it collision with itself occurs.
vale osprey
objects don't collide with themselves, they collide with other objects/components
make sure your components inside of the actor don't collide
nova heath
There's only one component
When I print out the class returned as the Hit Result it prints out the name of the blueprint though
It's a blueprint with just a StructureMesh component
Oddly enough it only happens when its directly in the middle of the viewport and only if you look at it from the side.
sage stag
is it sacrilege to import a 3d model to use as a landscape rather than using unreal's gizmo/generated landscape?
plush yew
Again, are there any mods for the subreddit on here?
wary wave
doubt it
the Reddit community seems to be it's own beast, largely unconnected with everyone else
nova heath
@vale osprey
I thought it might be colliding with the camera too, thus why I printed out the display name of the hit result.
Landscape is obviously a static object, but the "BP_Stone_Door" doesn't appear (and the issue doesn't occur) when only setting WorldStatic collision.
The blueprint seems pretty straight forward as well
all the division\rounding is just grid stuff it's not being used at the moment
vale osprey
print out name of the component too
ahh, you are not doing Blocking Hit test
add a branch there - always
vale osprey
its a first bool output of the Hit Results
nova heath
So it detects if Collision is "Block" rather than overlap?
vale osprey
I don't understand how its related to "object collides with itself"
the Hit Result is a structure that is reused by many different functions
so if you do a blocking hit test or a collision hit then you check Blocking Hit
if you do overlap test then you check overlap
in your case, you are checking if mouse is over an object
so if you want to exclude your door from that test, you can give it a custom object type that is not WorldDynamic
vale osprey
np
vale osprey
omfg!
now you can type -16.324 + 90 in a field and editor will sum it up for you
when was this added? 😄
nova heath
Visual studio added the same kind of stuff
You can also type times in VS and it'll give you the examples
Editors are getting better
I just realized what Blocking hit does and wow do I feel stupid
I wrote an entire other function get whether or not there was a hit lol
vale osprey
common mistake, if you don't do that check, you get all kind of garbage on output
nova heath
I actually wrote it a weird way to get around that lol

Plenty from the community and one officially from Epic for UE4 itself
Even a game template to DL and pick apart under Learn tab

Mmm never thought to check offical UE4 Thanks
Where? would it be in the learn tab?
wary wave
the best procedural generation articles will likely exist outside the sphere of Unreal
tranquil bone
What does that even mean?xD
glossy flame
It means they exist as resources for procedural generation as a discipline itself, not unique to UE4

A lot of the thinking in terms of that type of stuff has nothing (or very little) to do with the game engine itself, so tying it to a specific one would be somewhat of a hamper :p

How do I get the player character as an actor?
Like I know GetPlayerCharacter
But I need to get it as an actor reference instead of a character reference
glossy flame
Why? A character is an actor—it can be used in anything that requires an actor reference.
next ivy
I'm using an "==" node between a hit actor reference and the player reference
And since the hit actor returns an actor reference it is not seeing that as the same thing as the player reference
glossy flame
No, that's not why. Even if the reference types are different, if they both point to the same thing, it will still return true
next ivy
I have a Line Trace by channel between two actors
And I want to see if the player is in the line
glossy flame
Alright, then I'd try to do a little bit of debugging on the issue. Set a breakpoint where the == node is being used, and see what each actor actually is at runtime
restive eagle
technically this should work too http://prntscr.com/hqaoc4
glossy flame
Well, how about the branch itself?
next ivy
The node after the false triggered
glossy flame
You'll be able to see the values that are feeding into the and node
Okay, that's good to know, but breakpoints aren't only good for simply knowing if something executed 😃
next ivy
AH i see what you mean
glossy flame
It essentially pauses everything right there, and you can examine local variables at that moment
next ivy
Yea I know. I used them a lot with controls engineering
glossy flame
That's good hehe, you're already ahead of most people in terms of BP debugging
next ivy
Well that's weird. The line is hitting the actor even though I have ignore self checked
I could probably just throw the actor in the actors to ignore even though that would be redundant

Hey. unreal question. For some reason in my version of unreal. When I move the assets around in the scene the meshes randomly snap around etc. but I have vertex snap off..infact. When I hold v (vertex snap normally) then it allows me to freely move stuff around. What I do D: ?

There are, a dozen layers or so

Not entirely sure what you mean
The bottom part of the picture is the blackboard which has TargetLocation initialized

I know C# so i guess it wont be too hard compared to complete beginner

You should probably learn C++ if you plan on tackling code in UE4 although you can do most things with blueprints if you really want to

I know basic C++ been learning about 2 weeks
grim ore
Start there. There is even a coming from unity section.
Thats fine you can still start there and go to the videos
patent arch
bro thats like all reading?
next ivy
Well you're going to end up having to use reference material that is in writing. But yea you can learn the bulk of it from videos
patent arch
well shit how long is referance material you think?
next ivy
Most of the reading has pictures if that makes you feel better
patent arch
I hope
actually fuck it don't even know why i've bothered the past 2 weeks
no way im gonna be able to learn it no matter how long i try if i will have ot read

All the sections have a small related videos link. You can just skip to that if you want.

you think ill get the same as if i read
grim ore
But even then your going to be reading in the editor so you can't skip that

yea i know i can manage that most of the time
at least I can in C#
but syntax is a lot simplier

Hey lushen

do you think looking at the code in C++ is harder to remember than C# if its much harder there is absolutely no point of me attempting
cuz C++ is weird syntax and harder to remember than C# i think
honestly question
next ivy
Learning different programming language stacks on one another. Every programming language you learn will be easier and make future languages easier to learn.
patent arch
not what im asking thank you though
next ivy
C++ is a lot lower-level than C# as far as I know
patent arch
well shit
meaning weirder syntax?
thats what it seems at least
also do you think I can learn everything by watching videos and not reading? not to sound dumb but its completely not a option
next ivy
Yea lower level does not mean less difficult as some believe. It means the language is more mathematical and less like english
patent arch
oh
next ivy
Like Python is high level
next ivy
It doesnt have weird snytax. You're just referencing different things
patent arch
ok will it be more?
like wil i have to referance more things getting the same job done?
next ivy
In Python you might write someting like:
set variable to 5
in c++ it might be:
variable=5;
patent arch
Yea bro I know what you mean
I know C#
aight sorry for the questions I just get really frusterated with not being able to read anything
more then a paragraph
next ivy
Most would say low level programming languages like C++ are harder to learn than high level programming but I think it really depends on your brain
Honestly you need to learn to make documentation material your friend no matter what programming language you're doing

You should be able to follow written tutorials since they tell you to do things. If you have trouble remembering what you're reading thats fine because you'll be following along
It might tell you to click on this and then that and you can go and do that

what
next ivy
Written tutorials have steps that you can follow. And following those steps should make you remember how to do it

I don't personally agree with epic making money off of fortnite
the whole idea is obviousely playgerised
the only difference between it and pubg is graphics and the building feature
fluid stag
I think the only way fortnite would take players away from pubg is if it was a better game
last man standing is a gamemode that goes back to quake
only similarities is that you fly in and parachute, but I though there was a game before pubg that did that aswell
plush yew
before pubg was H1Z1 which was made by playerunkown as well
he said it didnt live up to his dream or what he had in mind
so he partnered up with another studio and set out to accomplish what he really imagined for his true idea of battle royale
fluid stag
the battle royale idea was around before all that though, and I'm not really sure if you can copyright a gamemode, I mean CTF or defuse etc etc are all game modes that came from somewhere, different games just put their own spin on it
same goes for mobas, you got many mobas now with almost identical setup, but no one is going to say that league of legends is the only one allowed to make money because the creators made the original dota or something like that
players usually decide who makes money in the end
plush yew
i agree with that but the fact that its a little more obvious that fortnite had the intent of cloning PUBG
they could've at least made it a little more unique
floral heart
The only argument against Epic doing battle royale is that they made the engine PUBG runs on and may have had some proprietary information from Bluehole. That's it. Anyone else making it could have easily taken anything they wanted from the Arma 2(?) mod.
