blueprint

[vernal grove]

Hello,
I want to destroy a destructible mesh near a spawned bomb, Can I trigger it through damage or I have to apply force/impulse on it?
For now I am using four projectiles in 4 different side they will destroy any overlapping actor but I want to replace those actors with Destructible Meshes .I want those destructible meshed to remain static.
These white meshes are destructible meshes.

[radiant mural]

I have a TopDownCamera and a ThirdPersonCamera, I switch between these, that works fine.
The ThirdPersonCamera is set to 'Use Pawn Control Rotation'
When I switch to the ThirdPersonCamera, I want it to have the starting location/rotation of the TopDownCamera.
This does not seem to want to work easily. I can kind of get this to work by disabling 'Use Pawn Control Rotation', but i have to re-enable it, and that makes the ThirdPersonCamera jump away from where i told it to be, even though the control is stationary.
How can i get the ThirdPersonCamera to start where the TopDownCamera is when i switch to it, but still have 'Use Pawn Control Rotation' active?

[trim matrix]

It isnt moving my character at all..

[spark forum]

Quick question about how to fix a blueprint issue I've got. As you can see in the screenshot I have a line trace which spawns a particle effect at the location of the trace hit result.

The problem: If there is nothing hit, it spawns a particle emitter at 0,0,0. Obviously in C++ I'd do a check to see if it even hit something then only play the emitter if there was a hit result, but I don't really know how I'd do that here. Any ideas?

[cursive ibex]

I want to update this actor text dammit 😦

[spark forum]

The fix for this was much easier than expected. All I had to do was add the logic for if there was a blocking it or not.

[prime pilot]

I'm following an yt rpg game creation series

and now i need to cast to my character

i understand the casting part but why do we need to plug in the try get pawn owner into the object

like what is (try get owner)/(get player character) doing?

I knw gendral cpp programming we used to create an object to a class but what is get player character doing ?

[icy dragon]

Try Get Pawn Owner = try to get Pawn class that own the skeletal mesh that use that particular animation BP

That node is more preferable than using Get Player Character, so that it work without having the player to possess it first.

[quasi widget]

Hi everyone. Hoping you can help me out since I've been stuck on this issue for a few days. Hope this is the right place to ask. I'm making a first person game where you can pick up items, attack with them and throw them. I have picking up, moving around, and throwing them set up, but I can't figure out how to attack with them. I guess the best way would be to set the rotation of the picked up item to about 45 degrees and then when I attack rotate the item, maybe? I've tried a few of the set rotation nodes, but nothing has worked so far.

[prime pilot]

Oh kk thnz for info. What if i have two bp class that owns the same skeletal mesh .

[prime pilot]

Which class object does (try get pawn owner) return in that case?

[icy dragon]

Doesn't really matter, as they're their own instances.

Note that it returns object reference, not class reference

[prime pilot]

I'm actually a beginner. Could someone explain what is the difference b/w object and object reference?😅

[brazen pike]

Do you mean object and class reference?

[prime pilot]

no i mean object reference like the blue pin

[prime pilot]

in cpp we used to create an object to a class and then use it to call a function

But here what is object reference

like try get pawn owner returns a reference object of the current skeletal mesh

[fiery glen]

anything that blue colour in bp is effectively a pointer in simple terms

but it also has to load it into memory as it is a hard reference

you can use that actor object reference to call functions on it

might be useful to do the basic bp course on learn.unrealengine.com

[potent laurel]

Object reference is just a reference to that specific object

[signal orbit]

what blueprint variable type would i use if im trying to create a slider in my blueprint details panel?

[mental trellis]

I don't believe any native types use sliders as their default details panel visualization.

All numeric variables inputs include a slider, though.

Just as well as a text input field.

[prime pilot]

thnz for info guyzzzzzzzzzz

[lusty rune]

Hi guys

it wont work

[potent laurel]

Is it necessary to set this by blueprint?

[lusty rune]

its level bp

i dont want to show it when the main menu is visible

[potent laurel]

Menu is normally a separate map itself

[lusty rune]

yes

[wicked osprey]

Guys, I wanted to ask you. I have a hierarchy of items: the main class Items and its child weapons, flashlight, key, firstaidkit and so on. I need to implement the R button for reloading in a weapon and for changing batteries in a flashlight. The question is, do you need to create this event (replacement) in Items or create them separately in the Weapons and Flashlight classes and get them in the player on the cast? Just for example, there is no action on the R button for a key or first aid kit

[potent laurel]

Anyway I'm not 100% sure why it's not working as I can't see enough info, have you got that gamemodes set in your level settings

You can use print string to see if that event is firing

[potent laurel]

You would be better making weapons flashlight and key their own class, or at least remove weapons into its own class

[signal orbit]

quite new to blueprints, i have a cone mesh attached to my skeletal mesh component and i'd like to be able to toggle the visibility of the cone on/off via the details panel of my blueprint. i've created a variable but for some reason this code isn't working. anyone able to explain why?

[mental trellis]

It's entirely up to you how you do it, @wicked osprey. Personally, I might use interfaces for that. Have the reload input trigger on the player character (or controller) and then try to cast the active equipment to a "ReloadableInterface" class, if it works, trigger the reload using the interface.

[mental trellis]

Or use some sort of generic base class for all equipment with a "IsReloadable" property

[prime pilot]

Here i have 2 classes class A and class B

I need to access a variable from class A on class B

[potent laurel]

Use construct script

[prime pilot]

So i created a casting on class B for Class A

[signal orbit]

construct script? how do i access this?

[potent laurel]

It's in the blueprint, it's a tab

[prime pilot]

now what should i plug in to the object pin of the the casting?

[lusty rune]

on top of the editor you are in the Event Graph

you should switch to Construction Script

[signal orbit]

ah understood, will report back

[mental trellis]

@prime pilot do you have a reference to an instance of class A?

[potent laurel]

What is the class parent called

Or the object

[prime pilot]

No parents just 2 classes A and B

[prime pilot]

No

[mental trellis]

The construction script won't run mid-game when your ragdoll is event is triggered.

[potent laurel]

Do you have that as a variable ?

[mental trellis]

You cannot just cast any random object (including self) to class A - you need an object/variable of that type to use.

[prime pilot]

and how do i do that?

[signal orbit]

gotcha, i don't think it will matter in this case as i'm simply using the cone as a debug tool 🙂 perhaps i'm wrong though

[mental trellis]

You solve this by doing blueprint tutorials and learning about object oriented programming.

[potent laurel]

Just drag the bool bar into construction script hook it up then it will do what you want to to

Toggle visibility from details panel

[wicked osprey]

And put interfaces into Items class or into classes where it need?

[mental trellis]

Put the interface on whatever item needs it.

...Do you know what interfaces are?!

Just out of interest. My suggestion won't make any sense if you don't.

[potent laurel]

What I find with blueprint is you can do alot of stuff the same in alot of different ways. It takes alot of exploring before you find the better ways and why. I still struggle with that, not afraid to admit

[wicked osprey]

Yes, i know

[mental trellis]

In reality, too, there are many different correct answers.

Just do it the way you want to do it.

[trim matrix]

hello guys

so iam trying to call an actor in thiredperson_BP

i used cast and in object i added get actor but its not working

so can i call an actor to 3rdperson bp?

any idea any one

[potent laurel]

What is the function you are trying to call

[trim matrix]

for now iam using print strings to success and failed

iam getting failed

[potent laurel]

Can you screenshot

[trim matrix]

ok

inside c4 there is nothing

[potent laurel]

This is from the player blueprint

[trim matrix]

yes

[potent laurel]

"get parent actor"

Of player blueprint

Isn't a bomb

[trim matrix]

i tried this also

[potent laurel]

Owner of a character blueprint isn't a bomb

Lol

[trim matrix]

then what should i try?

[mental trellis]

Where is the bomb coming from? Do you have a reference to it anywhere?

[trim matrix]

no reference

directly calling it

using cast

[mental trellis]

That isn't how cast works.

Cast works on references.

[trim matrix]

ok so i need to create some refences to that bomb actor?

[mental trellis]

Yes.

[potent laurel]

Yes that would work

[mental trellis]

And you need to set it to a valid reference...

[potent laurel]

What is the event going to do once all working

[trim matrix]

need to play some animation

[mental trellis]

On the bomb or the player?

Also, can't you just pass the bomb location to your explode event?

Or spawn event whatever.

[trim matrix]

on bomb

[trim matrix]

even if i want to spawn even also i need bomb right?

[potent laurel]

What is going to set the animation going

A button press

Or player location

[trim matrix]

a button press

i am checking did i pressed a button or not in character and making true in bomb so that bomb can play that animation

[potent laurel]

I haven't got enough info on how you are trying to do this to help, is the button working, have you checked it's changing the bool

[mental trellis]

Is the bomb spawning because the player did something?

Player clicks a button in their UI?

[trim matrix]

button is working i need to set true in bomb actor

[trim matrix]

bomb will already present in game map

[trim matrix]

s

not in ui

player clicks v button

[mental trellis]

And a v button is?

[signal orbit]

hey everyone, having a difficult time wrapping my head around this one

i've got a cone parented to the head of one of my skeletal meshes, and i'd like the angle of the cone to dictate the direction of impulse on the head. i'd also like the amount of impulse to be dictated by a simple slider on the details panel of my blueprint. how would i go about doing this? i've gotten this far with my code but i'm unfortunately stumped at the moment.

(perhaps i'm doing it all wrong 😕)

[mental trellis]

Your vector nodes are correct

Do you have a physics control thing in your animation bp?

I can't remember exactly what it is, but you need some sort of physics thing to make ragdoll work.

[faint pasture]

@signal orbit why are you calling an impulse a force

What exactly are you trying to do

[potent laurel]

2 people asking for sliders in details tab in 30 mins lol

[signal orbit]

yeah so my mesh is 100% set up correctly for physics, i've tested impulse on it and it works flawlessly @mental trellis

[mental trellis]

Or the same person, supsun?! 🙂

You need to multiply your force by something, nerf.

Try like 1000000

[potent laurel]

Oh, sorry lol

[signal orbit]

would i use a simple float to do that? @mental trellis

[faint pasture]

What are you trying to accomplish here?

[mental trellis]

Yes, nerf.

I would guess he's enabling ragdoll and trying to launch his character

[faint pasture]

What's that for to do with a cone being parented to a head?

[potent laurel]

I'm curious what that target variable is that's setting bone name

[signal orbit]

so, i've got ragdoll enabled on my character, but on top of that i'm trying to make it so i can freely add impulse to any bone i desire and customize the amount of impulse and angle of impulse. the cone i'm just using as a makeshift debug tool, where the angle of the cone determines the angle of impulse. @faint pasture @mental trellis @potent laurel

[potent laurel]

Ok, so can you screenshot the components list from this bp

[signal orbit]

yep, one sec

[potent laurel]

And what is the target variable set as

[trim matrix]

its an input action

[potent laurel]

Also you need to multiply the forward vector iirc

[faint pasture]

Impulse = cone.forward x magnitude

What's the problem?

You do want impulse right? You're NOT doing this on tick

[signal orbit]

yup correct

[potent laurel]

Use print strings on stuff everywhere, it helps alot

[signal orbit]

most stuff there can be ignored, it's simply for easy character customization

[potent laurel]

Wow

[signal orbit]

(not for gameplay purposes, just a film im working on 😄)

[potent laurel]

Ok, well for a start you need to attach most of that together

[signal orbit]

is there a node for magnitude?

[potent laurel]

This is normally done in the skeletal mesh itself

[mental trellis]

Float

Magnitude is just a float.

[faint pasture]

Dude just multiply the direction (a vector, cone forward) by the desired magnitude/strength/momentum change / unga bunga of the hit (float)

[potent laurel]

Lmao

[undone surge]

how would i make a variable that stores audio? what kind of variable would that be

[mental trellis]

It'd be an audio asset. SoundWave? Something like that.

[undone surge]

@mental trellis would i have to make a blueprint class for sounds and reference that? if i want to customize it? or would i just store the sounds in that variable itself

[mental trellis]

As far as I know, UE doesn't have an audio editor.

You can use pre-recorded sound?

[brazen pike]

What are you trying to do?

[undone surge]

i was trying to store a different audio file in each child class as a variable. i managed to figure it out i think

i did this

[mental trellis]

You may want to use a subclass of Sound Base

I doubt it's meant to be used directly unless you're looking to use differnet classes of sound

(Such as Sound Wave...)

[open latch]

whenever I put a Destructible mesh into a BP I get these results. anyone know how to disable that exploding one ...

Probs with the settings of it

[open latch]

the settings on the destructible mesh itself or the settings in the BP ?

[mental trellis]

The mesh

The mesh component, that is.

[fossil oxide]

Hi, I would like to make a system which highlights (post-process outline) holdable objects.
The only problem is blueprint interface react fewer times than it’s called. Print String “control one” is showing two times more than Print String “control two”, I hope you can understand me. I attached screenshots above.

I've already posted this on the forum, but I haven't received any reply since three weeks.

[mental trellis]

I would follow a tutorial on post process outlines.

[keen schooner]

This is also how I've done it in my system, storing a reference to audio files for each item in different use cases (item picked up, moved, dropped, etc). Seems to work fine.

[undone surge]

i see

[fossil oxide]

Outline works good, but the problem is my blueprint interface which is calling outline

[lunar coyote]

https://i.imgur.com/TU9JpYa.png

Is there any way to forcibly set an object to become nullptr?
I want this to become false in a IsValid check, but once I've set it, I can't seem to un-set it.

What I'm doing there still results in a true IsValid

[solar bison]

How do I do check for multiple elements in array?

const values = ['one', 'two'];

return true```

[lunar coyote]

@solar bison , you can loop over values, then in loop body, if arr fails to contain element, break with false, otherwise, it contains them

https://i.imgur.com/cjogTVJ.png

Something like that

But also set a result before breaking

[trim matrix]

Ugh I can’t figure out how to add flying

[solar bison]

ty

@lunar coyote my values are fixed so I always know what I need. I just do a "contains" 2-3 times and join the pins 🙂 (no loops)

[wicked osprey]

Guys, I have a question what to do Create methods in the parent class and override them where necessary. Or create interfaces and add and implement them where needed?
What is the best practice?

[mental trellis]

What do the create methods do?

[solar bison]

Lol UI bind runs on tick????

[dawn gazelle]

Yep

[solar bison]

Why????

Why is it not event based?

Also, can I not set variables on PlayerController like this in a Widget BP's graph??

[dawn gazelle]

For most use cases, it's fine. If you have several thousands of UI elements bound does it really seem to make any difference - mileage also varies if you're doing some complex calculation in your bind returns.

[dawn gazelle]

Sure you can.

[solar bison]

Nvm, I was binding it to my endturn event and not roll dice event XD

[thin panther]

UI bind gets run every time the widget gets drawn to screen, which happens on tick

[solar bison]

is that even efficient? I wonder if Unity does their binds this way too

[solar bison]

i'll take this as face value

[thin panther]

As datura said it really depends on what you do, if your bind is just seeting some text, or displaying an integer, while not maximum efficiency, its really not gonna hurt performace

If it's full of complex calculations that dont need to be done every frame, then it may hurt it a little bit more

[vapid edge]

hi, not sure if I'm asking in right place .. but i have this custom input that does an attack in my game ....
but i wanna enable it after the player reaches a certain location and triggers a trigger box ... can someone guide me on how to do this ,.... I'm somewhat new to unreal and blueprints

[brazen pike]

You can set that in the player blueprint, so the trigger will enable a bool and that bool is checked when the player tries to attack

[vapid edge]

not in level blueprint ?

[brazen pike]

You can, but its really not advisable.

[undone surge]

is there a way to blend noise into silence? my sound ends abruptly i want it to slowly fade away

[maiden wadi]

Parent class and override. This is the intended way to do things. Don't create unnecessary interfaces. They are functionally slower than a simple case to the parent class, and they are harder to follow in a code base. It's just confusing.

[limber jacinth]

@undone surge There is a Fade Out Node for sounds. https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Audio/Components/Audio/FadeOut/

[undone surge]

thnx

[undone surge]

i will put this in the main graph right after i put the play sound at node ?

[limber jacinth]

Here is a tutorial for fading in and fading out sounds. https://www.youtube.com/watch?v=Tles_r-XkY0

[undone surge]

i was in the middle of this video xD

thnx

[limber jacinth]

😄

He explains it pretty well from what I can tell.

[undone surge]

yes

[undone surge]

what do i put in the target for this node , the sound isnt plugging in

[wicked osprey]

And what to do in this case if several classes (weapon, flashlight) have the logic of "reloading" It would be better to create the Reload interface and implement it in these classes or create a Reload method in the parent class. Then it turns out that it will be inherited in objects of type Key, FirstAidKit, but will not have an implementation. Which of these solutions would be more correct?

[thin panther]

Reload in parent class

Interfaces are more for where you need it across things

Only weapons will need to reload

But interaction can happen on weapons, npcs, items, doors

Thats where you distinguish the too

But really a key wouldnt be a weapon

Nor a firstaidkit

Id class those as consumables perhaps

[wicked osprey]

the fact is that I also have a flashlight on the R button with the logic of replacing the battery😅

[thin panther]

That one makes sense

But not a key or medkit

With that you flashlight would be a weapon

Just have a bool on each that says if they shoot or not

Flashlight would be no

Or the shooting logic would be overridden to say just turn it on or off

[maiden wadi]

Yeah. I wouldn't use an interface for something that functions identically to something else and can share a base class.

[wicked osprey]

That is, it will be necessary, roughly speaking, such a hierarchy 1) ItemsWithReload 1.1) Flashlight 1.2) Weapons

hi guys

I am new to unreal and in desperate need of help!

I am developing a game for my masters thesis , and as a part of its function, I want to be able to read a postgres table (which has geometries stored in it) and render those assets in runtime.

Next I want to be able to select one of the assets and drag and drop it on top of the world (like how we do it in minecraft).

Any help or resources would be highly appreciated

Thanks!

[violet tendon]

Question this should be quick. What would i want to use to find a point on a wall to the left and right of the player so i can pass that vector onto my grapple component

[thin panther]

maybe draw a diagram

theres lots of ways of interpreting that

[obtuse herald]

Line trace?

[thin panther]

are the geometries just stored as vertex positions

[violet tendon]

Green being my player and his view. Red being walls that are in his view. I would like to grab a point on that wall furthest from the player. But im afraid of using linetraces on every frame because if there is no wall there would be wasted resources

[thin panther]

i mean linetraces are fairly cheap

try it and then see

but what you can do is cast from the right vector and right vector -1

to a point in front and to the right/left

always try your idea, then profile it, if it causes noticable performance differences, then change it

if you do this line trace, and its still cheap on memory, frames, etc. then keep it

[violet tendon]

Thanks will try that out! Appreciate the help!

[thin panther]

no problem!

[true valve]

How can you throw yourself forward as a ragdoll ?

[dark crow]

AddForce? Idk what you mean exactly

[red fossil]

👋 Anyone know how I can get movement input to always be inherited to where I'm facing?

Explanation: Currently, movement input is determined by the pitch of the player. However, when they change pitch, the momentum in the old direction continues to push them that way instead of being transferred to the new direction. Think of a diving bird that would gain speed when it dives, and keep that speed for a while after it levels out. Right now it behaves more like a spaceship with no dampening. Any way to fix this?

Here's a video of it. I'm using "flying" mode btw

[gentle urchin]

Do you want to null out pitch?

Or inherit only pitch from view forward?

[red fossil]

I think the last one?

Pitch directly controls the input axis and that part works fine

[faint pasture]

I run 2000 line traces per frame. No problem.

[red fossil]

but that momentum I get from pitching down stays in that direction until it slows down, it doesn't push me forward, because it doesn't actually care what angle I'm at

basically any momentum I get from diving should be put in the direction I'm facing

[rotund marlin]

After changing over to EOS from Steam Now my lobby launch is completely crashing the entire client on Stand-alone test with 0 event begin-plays connected or anything else Starting soon as level is loaded Jikers

[earnest tangle]

I would apply the momentum into velocity instead

so you apply it into velocity in the direction of movement, so it would always go into the direction you're facing, assuming you're moving into the direction you face

[red fossil]

Into character movement?

[earnest tangle]

huh?

[red fossil]

like this?

[earnest tangle]

Something like that yeah

[red fossil]

hmmm

It did work, but I was having issues with replication so that's why I'm trying the movement input instead.

[undone surge]

how do u randomize the pitch and volume with metasounds like the modulator did in sound cues

[rotund marlin]

fml.. cant figure out what crashes the game, no matter what map i host or open it goes down

[earnest tangle]

Try #audio maybe

[undone surge]

ok

[gentle urchin]

You're not ordinary lol

Im capping at 300, above that fps drops start to hit

[maiden wadi]

It also depends on how they're used. Short traces are much faster than longer traces. And C++ can optimize a lot with lack of copying so much data.

[gentle urchin]

Doing c++ ones but prob a lot of datacopy

[lavish totem]

Im running sprint on event tick since i only want to sprint when moving forward. I used event tick so it updates immediately. Is that good or is there another way?

[wispy wasp]

id suggest adding an action keybind for sprint in your project settings cuz running things on event tick is generally avoided if possible

[stuck trench]

@hereanyone know why is there an error in Signature and I'm not able to choose my custom event: "OnVideoEndReached" ?

[lavish totem]

yeah it doesn't update as quick as event tick, I tried a lot of stuff, nothing worked

[thin panther]

yes it does?

if your sprint doesnt work with a keybind then thats the issue

[lavish totem]

when you press the key, yes

[lavish totem]

it does

[thin panther]

and thats the issue

you should use an input action

it doesnt need to be on tick

if input actions dont work then the player wouldnt be able to move, as movement inputs are handled though input actions

[lavish totem]

The thing is, that i only want the character to sprint forward, It could be bypassed if i dont use event tick...

[thin panther]

what?

[lavish totem]

it sounds complicating ik

[thin panther]

why not just check if the w key is pressed when shift is pressed

[lavish totem]

you just have to see for your self what i mean

i did that, but if the play hold shift and w, he can release the w key and can sprint backwards and left and right

[thin panther]

the onyl problem with that setup is it won't respond to changing keyubinds

which is likely something youll want in a settings menu

but really, only you can tell if its gonna cause issues

profile it

with and without

does it make for frame drops, or other performance decreases

casue if it doesn't then it's fine

[lavish totem]

Nah not really

[thin panther]

have you profiled it or are just looking for stutters

have you gone through the performance tools and checked

or are you just looing at the fps stats

[lavish totem]

both

[thin panther]

well then

it works

so keep it

its fairly light code

if you need it so that you can only sprint while holding shift and w

then you need to check that on tick

its certainly an unusual sprint system, but if that's what your game needs

[cobalt gulch]

Why is this script not showing the variable in the text?

[wispy wasp]

you should check if the cast suceeds or fails. if it fails then it could be that u didn't set ur game instance in project settings

[cobalt gulch]

ah thanks

you little wizard 😉

[wispy wasp]

i would also recommend against binding text like that, typically u would do the casting once at even construct so u dont cast every time u update the text

[cobalt gulch]

True

What would be the best way to have it so money variables are saved so that if a player leaves they can't cheat and have their money reset

[cobalt gulch]

In an automatic fashion

[wispy wasp]

If you mean after quitting the game then you should look into making a save game if its just changing levels then game instance, as for preventing cheating i have no idea

[cobalt gulch]

Can I make it so if they leave it automatically saves?

[thin panther]

ye if you set up an auto save

theoretically you could hook into the exit game in c++ and save everything

in bp you can make autosave timers

but there nothing to just say "hey save everything" unless you make a system to do that

[cobalt gulch]

would it be like a script in the game instance which is like "event tick, delay, save game"?

[tight schooner]

try Set Timer by Event node for periodic events

[thin panther]

i would probably have it in the game instance on a timer, my personal chocie is 3 minutes

[cobalt gulch]

Oh I could also just save the variable after updating it i guess

Lol

Like make an event for when its updated

Then save from the event

[trim matrix]

Hey guys I need help

[thin panther]

with what

[trim matrix]

So I have this project

Like an open world hero game

And I’m so confused on the super powers lol

[thin panther]

first off open world project as a beginner is not a good idea

[trim matrix]

Rude

I’m great

At open world shit

Plus

[thin panther]

unfortunately true

[trim matrix]

I aight no beginner

[thin panther]

the amount that goes into an open world game is too much

[trim matrix]

I’m an amateur

[trim matrix]

First off, it’ll take a while yes but it’ll help me learn

And second I don’t give a fuc that it’s too much bc I’m will to put the time and hours Into lol

Bc am retart

[thin panther]

not knowing when to add variables for stuff is the definition of beginner

[trim matrix]

I’m an amateur 😠

[cobalt gulch]

You're not helping rylan

[trim matrix]

How

Wait what?

[trim matrix]

I’m the one asking for help?

[cobalt gulch]

These people are trying to help you so help them

[trim matrix]

U made me hurt brain

[trim matrix]

How?

[cobalt gulch]

Be respectful

[trim matrix]

I am

[thin panther]

im trying to demonstrate why this is a bad idea

an open world game when you were struggling to know which variables to use is a bad idea

[faint pasture]

You can lead a horse to water but can't make it drink.

[thin panther]

you will likely burn out

[trim matrix]

Ok what is gud for a “beginner”

[thin panther]

do some very simple small projects

but often

[cobalt gulch]

Try a mechanic which is simple

[thin panther]

like maybe a platformer where you pick up coins and get score

[cobalt gulch]

For example start with picking up an item

[thin panther]

that will get you used to changing levels, adjusting movement, collisions

then maybe a puzzle game, that can introduce manager classes, and combinatorial logic

really simple stuff like that

[trim matrix]

👍

[thin panther]

then maybe work on individual systems

so maybe try and make an inventory system

[trim matrix]

Inv system?

Fun

[cobalt gulch]

Make a sex mod or two

[thin panther]

but inventories are significantly more advanced

[trim matrix]

No sex

[thin panther]

so thats something to do after youve done the basics

maybe make a simple game where you shoot targets, but can pick up various weapons

[trim matrix]

Gud idea

Wait wtf

I just open a blank project in unreal and it had gave and chairs?

[thin panther]

yeah

starter content

there is a small collection of assets and materials that you can choose to include

[trim matrix]

Oh Yh

[frozen spear]

Rylan, you say you're not a beginner you say you're an amateur... Okay that would imply that you use the engine for a bit... You know the basics... But you just said right now something that happens every time you create a blank project... You were surprised to see chairs and a table and a little decoration on it... Do you want to be a little more honest about what level you're at with the engine

[trim matrix]

Wait @thin panther what is better projectile gun or linetrace?

[thin panther]

Depends on your needs

[trim matrix]

Yh I start with third person one not blank one..

[frozen spear]

And in your whole time you've never created a blank project?

[trim matrix]

Nope

[frozen spear]

Is it safe to assume that this is your first year in the engine?

[thin panther]

A hitscan gun may be really good for an fps game but absolutely useless in a bullet hell

[trim matrix]

I didn’t need it

[thin panther]

Third person has starter content too

[trim matrix]

Ik

I use it for the character

[thin panther]

But you may also combine the two foundations

Like hitscan for your main weapon, but projectile for a grenade launcher

[frozen spear]

https://yourgameideaistoobig.com/

[trim matrix]

Ok

[trim matrix]

What’s this link?

[frozen spear]

Here's why they said open world is too big for a beginner or even one person

[trim matrix]

I have seen a rly gud open world by only 1 person

Rly gud it was

[frozen spear]

$$$ = time

[trim matrix]

Time = £££…

[thin panther]

my dream project ticks those boxes

[trim matrix]

18 grand?!

[frozen spear]

Anyways i like your passion... That's a huge part of doing game dev...

[thin panther]

with smaller tarkov-style levels to explore

which are easier to fill cause i focus on lowpoly assets

[trim matrix]

Who’s passion?

[thin panther]

yours

[trim matrix]

Oh mine?

[thin panther]

you want to do the stuff which is good, you just need to relaise your skill level

whats it called... the dunning-kreuger effect?

[trim matrix]

Eh?

[frozen spear]

Yours... But learn to not get defensive... Everything becomes much harder when you solo Dev and have no where to turn for help when you're stuck...

[trim matrix]

And when my slow ass laptop is slow

[thin panther]

you starting to look pretty high on the top peak

"The possibilities are endless! im going to make a great open world"

when you cross into the average threshold you start to understand scope

[frozen spear]

Scope and scope creep

[thin panther]

yup

[trim matrix]

…

[thin panther]

i keep thinking, ooh it would be cool to add x to my game

[trim matrix]

Can y’all realise o have 3 brain sells?

[odd ember]

this is not accurate enough

those estimates are way too low

[thin panther]

but then i realise multiplayer is a whole other bag of tricks

[trim matrix]

Multiplayer = too hard

[thin panther]

ikr, 4 months for a fps, rpg, vehicle with crafting

[odd ember]

3 months for a mmo? you gotta be joshing

[thin panther]

pffft

[frozen spear]

What features tho...

[odd ember]

porting to all platforms taking 1 week 😂

if that were the case porting studios would be making BANK

[thin panther]

i mean an mmo where all the players just load into an empty void might work

in 3 months

[odd ember]

nope

not even close

[frozen spear]

Or one without customization,stats ,or gear

[thin panther]

i mean you just hire a server and get people to join it, and thats it

technically an mmo if enough people come

if all you have is a bunch of empty world, where players just load in to look at nothing seems feasible in 3 months

like literally 0 mechanics

[odd ember]

yeah but you're implying that the setup for that is free or cheap

which it isn't

[thin panther]

i never said that

[odd ember]

.

[thin panther]

i said you could implement it in 3 months

i never said the cost

[trim matrix]

Breh my laptop been loading file explorer for 5min now

[frozen spear]

Whats the stats in your dream game ce?

[thin panther]

3 months is not a price

[odd ember]

the cost is in time, not currency

[thin panther]

but not in this specific case

im talking about the time to make an empty world is probably possible in 3months

as you have to do nothing

[odd ember]

I'm telling you that's not enough time 😂

[frozen spear]

I want to see what kind of MMO what were checked off in the list...

To estimate 3 months

[faint pasture]

Precedent has established those are equivelent

[trim matrix]

U stole mah message

Hehe

[odd ember]

but they're not. time = liquidity * currency

[frozen spear]

I have more money than time

[trim matrix]

I have no cash or time

[trim matrix]

Hehe

[frozen spear]

And you want to do an open world game lol

[thin panther]

then an open world project defo isnt the thng 😆

[odd ember]

actually

time = liquidity * currency * communication

[trim matrix]

Ok ok chill I have time but not like 13 hours a day mayb like 6-9 hours a day

[odd ember]

people assuming you can just hire people and it's a done deal

but you need to manage those people 😂

[thin panther]

yup

business aint just "do work"

[faint pasture]

Hire a manager.
Rekt.

[frozen spear]

Really though just out of curiosity can you post a screeny on what you checked off that gave you three month estimate on an MMO

[odd ember]

you have to manage the manager 😂

[thin panther]

cause most people given the chance are gonna do as little as possible for their money

[thin panther]

hire a manager manager

[frozen spear]

Cuz if you make one with even the most basic features it seems to throw it into years right away

[odd ember]

the manager and manager manager will be fighting for control

I promise you

[thin panther]

then hire a manager manager mediator

[trim matrix]

Then you’ll have to manage that manger that is managing the manager

[thin panther]

i have all day and nothing to do dont tempt me with this pettiness

[faint pasture]

I can make an MMO in one day. Just email me your character name and I'll email you a description of what you see.

[thin panther]

manager manager manager

[thin panther]

cool whats the email

[odd ember]

but then you have to hire a manager manager mediator mediator as well, because one mediator will not be enough for just the managers. while they're fighting the team won't know what they are doing

[thin panther]

youve found a niche in the market

[thin panther]

hire god to solve it

checkmate

[trim matrix]

No

[odd ember]

you'll have to hire people to construct a shrine first

[thin panther]

well thats easy

[trim matrix]

Hire the queen to solve it checkmate

[faint pasture]

Anyway this is getting very reddit and cringe

[thin panther]

i might even hire a shrine constrctor manager

[faint pasture]

Just have your org tree be a wreath and it's solved.

[trim matrix]

BRB

[thin panther]

i like it

[odd ember]

that's right, give your junior developers the ability to overthrow the CEO

I'm sure that will end well 😂

[thin panther]

but then you get overthrown, so you just overthrow them back as you are now the bottom of the food chain again

the beauty of the wreath

[odd ember]

only if they don't change the hierarchical structure while you're not in power

you'll have to wait until the culture gets too decadent 😂

[faint pasture]

Take your time.

[frozen spear]

Dude, you can't say it's not accurate and then all you selected was MMO meaning no features

If in 3 months you can't make it where people can load into a big empty map with no features on their characters at all you need to just quit kind of

[odd ember]

you're underestimating the cost of a MMO alone

even without features

[frozen spear]

Just take the L dude you selected one box

[odd ember]

but by all means

go try 😂

[zealous moth]

HahahHahahaa the mmo meme

Where is your customer care?

[odd ember]

no problem just solve it in 3 months

[thin panther]

who cares about customers... it's 2022

[odd ember]

server stress testing? done in 3 months 😂

[faint pasture]

Nobody here is gonna make a traditional MMO so let's just move on.

[zealous moth]

Yeah exactly. No Cc, no new content. I forget who it was but they made a successful Diablo clone. People plowed through content in weeks and they couldn't keep up

[faint pasture]

Disregard content, acquire emergent gameplay.

[odd ember]

someone still needs to make the systems to allow emergent gameplay to happen 😂

[zealous moth]

I jest but you should look at at least a 100k budget if not more and hire a dedicated artist, programmer and server guy and then customer care. Afterwards figure out a way to advertise.
Remember candy crush spends 1 mill daily on ads and makes back their money

[odd ember]

devops alone is going to cost you

not even counting content

[dapper iron]

So I'm running into this issue where On Component Hit event is not fired on my BP if the Simulation Generates Hit Events flag is set at runtime.
If I set it on the BP at edit time, the event will be raised when the component is hit, but not if it was disabled at edit time and later enabled at runtime.
Funnily enough, even at that state, if I disable and re-enable it in the details panel while the game is running, the event will suddenly start being raised again, but not if I have BP nodes to do the same thing...

Any ideas?

[zealous moth]

@odd ember

[thin panther]

easy

[odd ember]

that's still under estimate 😂

[thin panther]

ill just ask for a dollar outside mcdonalds and keep doubling it with epic crypto things

i'll have the entire us debt within a year

[trim matrix]

@thin panther

I have a question

[thin panther]

then ask it

[trim matrix]

Ok

For the game idea u suggested

Should I start with picking up guns?

[thin panther]

i wouldnt start with the gun one personally

i would start with the platformer

its easiest based off the side scroller project

[trim matrix]

What was the platformer*

[thin panther]

just something very simple

pick up coins

get to the goal

avoid the spikes sorta thing

[trim matrix]

Ohhh

Like subway surfers?

But better

[thin panther]

ye ig

but very simplistic

[trim matrix]

K

[thin panther]

all greybox

just pick up coins, dodge the traps, finish level

[odd ember]

pick something that you can do within the template level that the game gives you

[thin panther]

that will cover most of the absolute basics

also very fair

the side scroller template is the perfect setup for that

[trim matrix]

Ok

Ty

I start as soon as I get back from walking my dogs

[gentle urchin]

Super mario platformer ?

Go from a to b in a fixed panspeed, jump a little

Gotta be some of the easiest one can do ?

[flat coral]

1. What's the difference between these?
2. Why isn't Get Physics Linear Velocity a pure function? This thing have side effects?

[unique smelt]

Is it possible to access a parent levels blueprint and events from a sub level while level streaming?

[maiden wadi]

Generally things with Physics in the name relate specifically to objects simulating physics. Component Velocity can be updated through Physics or via some form of movement component like a FloatingPawnMovement or the CMC.

[maiden wadi]

Generally speaking, nothing should reference the level blueprint. They're meant to be self contained things that house specific logic relating only to their own level. If you need the rest of the game to know something, delegates in places like GameState are an easy way to handle that. Both have access to GameState and can bind that delegate or call it.

[earnest tangle]

I wonder if you could build a game entirely ad hoc with no blueprints and everything built in a level 🤔

[thin panther]

i mean ye probably but it would be really stinky

although a lot of newbies do seem to use the level bp for everything

idk why

can someone tell me where it comes from

[earnest tangle]

it makes it super easy to reference to objects that you have in the level

that's most likely why

you don't have to figure out how to get a reference to something

[reef topaz]

Have a combo box that has a base selection set through the set option node but doing so makes the selection noise as you enter the UI page. Tried doing this to set the selection noise after I already selected the initial option. Now selecting things in the combo box drop down doesn't trigger the newly set sound effect.
I know I'm missing something but I'm not sure what.

[thin panther]

far enough, dont have to think about pointers when theyre all there

[flat coral]

Is there a way to get a vector that represents a line from Location A to Location B?

I guess I'm thinking of something kind of like Get Look-At Rotation

[thin panther]

thats what a vector is

it describes a direction between 2 points

[earnest tangle]

DestinationPoint - SourcePoint

This gives you a line from source to destination

If you want to use it as a direction vector, you can just normalize it

[crimson hornet]

Hey guys I got an quick question. Does someone know why my max walk speed isn't getting +1500

Event is getting called

[maiden wadi]

Check that the execution line is actually being ran. Also check that nothing is setting it back too soon.

[maiden wadi]

Colleges use them a ton from what I've seen. There isn't a lot of correct class usage taught early on I suppose. Possibly more designer oriented courses than programming.

[thin panther]

really? my course was designer oriented and we were taught to use the proper things

[charred berry]

Why did ue5 remove the 'sphere' as part of new bp , is there an easier of getting that back or do we just have to put a sphere around the new, default, odd looking thing ? ;))

[thin panther]

we used level bp in like the first day just to get used to stuff

but we soon moved into classes

[stuck plaza]

Is there any workaround to Dynamic delegates not taking payload? I have this delegate with signature void() that I'm binding function to. I want to pass some arguments to that function during binding because otherwise I'd have to make multiple functions that are almost the same except 2 variables. I know in c++ you can pass payload data, however this is not possible in blueprint according to the docs, is there any way to avoid flooding my bp with dozen of almost identical functions?

[brazen pike]

You guys got taught this stuff? Damn maybe I should look into that

[maiden wadi]

I dunno. Have been in this Discord a while and there's been quite a few college students in here who have had to use level blueprints for their college projects.

Stuff like their professors give them a project all in a level BP and they have to alter it in some way.

[thin panther]

i mean we only got taught basics

i self learned mostly

unfortunately most of the course was drawing

which is odd for gamedesign

didnt actually cover any principles of game design

just drawing, and modelling mainly. basic comp sci, and a little bit of bp

[reef topaz]

Relating to my previous question does anyone know if there is a way to "refresh" a combo box that isn't just refreshing the strings? I get the feeling that my problem is coming from it not looking at the style struct after the combo box is initially made so me setting something new in the style struct is just being ignored.

[maiden wadi]

Haven't set foot in college. 😄 Probably over 90% of my learning is from this discord, personal experimenting, and tech blogs.

[maiden wadi]

You cannot from what I'm aware of. The widgets used for view are created at option add time if memory serves from the underlying slate code. So they would need purged and readded.

[reef topaz]

Well damn, so aside from just leaving the combo box blank there's no way in BP to mute an initial combo box selection?

[maiden wadi]

Not fully sure I understand the question? Dynamic multicast delegates don't work any differently in BP than C++.

[trim matrix]

@thin panther 2d or 3d sidescorller?

[maiden wadi]

As far as this, I tend to not use the default sound stuff. I play sounds on the Selection delegate from the combobox based on the enum type it sends back.

[reef topaz]

I appreciate the insight. My understanding of C++ is minimal coming over from unity and while I have poked my head into the underlying code for unreal the syntax compared to c# is just not something I have my head completely around.

Will try your suggestion.

[thin panther]

3d

[trim matrix]

Bet

[stuck plaza]

I have a UButton variable and I want to bind it's OnClicked to my custom function.
The function signature is required to be void() so I can't pass additional arguments. In c++ I could pass additional payload arguments.
e.g.
In c++ I could bind a function void(int32) like this
MyButton.OnClicked.BindUObject( &MyFunction, 20);
even though OnClicked signature is void()

edit, actually I couldn't because OnClicked is dynamic delegate and they can't take payload

[trim matrix]

Thought 2d would be too hard

[thin panther]

nah 2d is actually easier, its just your aims seem to align with 3d more

[trim matrix]

Oki

Hi, SetPlayerCameraManager is missing from PlayerController

How can I assign?

[reef topaz]

This worked out really well. Thank you.

[maiden wadi]

Typical use case for this is to put a UButton in a UserWidget. And have a delegate in that UserWidget with your data you want to pass through the delegate. And have that UserWidget bind the UButton's OnClicked and call your Userwidget's delegate in that.

[shrewd oar]

General question, I'm trying to do (for now) basic single melee attack, I was wondering if should I put the "Damaging stuff" inside the weapon bp itself (Sword/Hammer) or should it be on the player itself?

[trim matrix]

Ehm I rly need help

So I made a launch pad

And

I can’t figure out how to turn the boost down?

When it’s float * float instead of 3 should I turn it down ?

Dw it was

I got it now

[mental trellis]

Weapon.

[maiden wadi]

Really depends on the use case. A character that could swap weapons, it should probably go in the weapons. On the other hand, if you have a bunch of different enemy types and their weapon is mostly just visual, it could be okay to put it in the enemy.

Normal use is to put it in the weapon, if the weapon is an actor. Reasons being that multiple different character types could use it or it could be moved to another character and still function if you need to swap weapons. They can be discarded on the ground etc. Again, all just comes down to what you need and what is simple for your game style.

[mental trellis]

Google abstraction and normalisation.

[shrewd oar]

Im trying to deal the damage sometimes its register sometimes is not, even made the collider bigger, nothing

[maiden wadi]

Which event are you using for damage?

[shrewd oar]

after the last set there is a print

I didnt use the Applying damage system thingy.

its does do the damage but i think only like after im spamming the mouse , and sometimes it does count

even if I make the collider big

its that big

[charred berry]

Not finding simulate physics for static mesh in ue5 ( tick for static mesh as in ue4), is that gone, only to be set now in Bp's ?

[mental trellis]

Static meshes don't simulate physics. Static mesh components might...

[thin panther]

what would be the best way to do melee damage? constant checking via trigger on the blade, or something like an anim notify with a short linetrace

[blissful grail]

Eh - depends imo.

I prefer the anim notify approach personally.

[mental trellis]

Can you not just use an overlap event?

[blissful grail]

It can be a bit annoying to actually get it right however.

And yeah, just using an overlap event is sufficient.

[charred berry]

watching a video where a sim physics was added to static mesh for a rope project, but it was in ue4, so your saying it must now be simply done in bp's ?:

[thin panther]

thats what i mean by trigger, checking to see if the blade overlaps

[maiden wadi]

It's important to check for overlap at the beginning of the swing animation though too.

[thin panther]

i just wondered if it was something best kept true to form, or to hack it slightly

[mental trellis]

Sorry, I was being pedantic about the differences between static meshes and static mesh components.

[mental trellis]

Why would you need to constantly check it? Surely the engine does this for you when it moves.

[charred berry]

np, actually I'm wrong sorta, he didn't use a static mesh, but a sphere,,odd, mazybe thats why I'm having trouble,,or or they interchangable ;l0-0

[mental trellis]

A sphere is a static mesh.

[charred berry]

yup thats what I meant

[mental trellis]

Well, if it's a mesh..

[charred berry]

ok ;0-0

he just added it in bps via 'add' > sphere

[mental trellis]

Was it a wireframe thing or an actual sphere?

With a texture.

[charred berry]

sphere, white

ue4

[mental trellis]

That'd be a static mesh component rendering a sphere static mesh.

[charred berry]

ok

[trim matrix]

i did it 😄

I did obstacles and shit

[charred berry]

can you verify, doing that, there is still no physics> simulate physics option in ue5, I can do in BPs I guess, or maybe I need to find a ue5 rope tut LOL,,gezzzz

[trim matrix]

No tut

[charred berry]

I was asking daekesh, but ty just the same

😉

[thin panther]

yes thats the point, its a constant check whether i force it to be or not

[mental trellis]

It's not exactly costly, though.

[thin panther]

no im wondering which is best done

never said costly

i wondered what would be the best way

[blissful grail]

There is hardly ever a "best" approach.

It just depends on your needs

[thin panther]

well ok best was poor wording

what i mean is how would others approach it

[blissful grail]

I prefer using anim notifies because it gives me more precise control on when the damage window for a swing actually is.

[mental trellis]

It depends on the weapon too.

A big arse hammer you're swinging is gonna damage everything all the time.

A knife might not.

[blissful grail]

It really just depends on your game. As long as you know how to do both approaches - just do the one that makes the most sense for your game.

[thin panther]

yeah i can do both, i was just wondering if there were issues with either way

more of a general consensus

[mental trellis]

One based on anim notifies that only triggers at the end of a stab or swing animation is gonna feel bad, though.

[thin panther]

yeah definitely

[blissful grail]

Well yeah - that can be said for anything though.

I could just as well argue that it would feel bad if you do the damage when you raise your sword instead of on the downward strike or a straight thrust.

[mental trellis]

You might do a little bit 😛

You could base the damage off the angular momentum of the end of the sword.

Or maybe just the straight speed of the centre of the blade, as a balance

[blissful grail]

Could also just do damage every second that they're overlapped.

[shrewd oar]

How can I do Tapping in left mouse event ? and not holding

[blissful grail]

It all comes down to your game

[shrewd oar]

the pressed & released very annoying

[trim matrix]

Wait guys how do I make a Home Screen?

[short pawn]

do you mean like a title screen? you can make it with widgets

[trim matrix]

Oh Oki

Do you need to add bp for it to like start the game?

[thin panther]

good melee does damage on every tick, but not normalised by delta time

[trim matrix]

And shit like that

[thin panther]

insta kill baseball bat

[short pawn]

this is the first result for a google search

[short pawn]

https://www.youtube.com/watch?v=K1vVbwMJCTQ

[trim matrix]

E?

[short pawn]

goodluck, google helps alot. lots of people have figured the basic stuff out for you

[trim matrix]

I’ll prob need the luck tbh

Welp brb I’m watch this see what I can learn

[shrewd oar]

How can I do Tapping in left mouse event ? and not holding?

[maiden wadi]

Using a float is a good method for that.

To elaborate. You can get RealTimeSeconds globally. This isn't affected by pause or dilation. So you save this into a float property on mouse down, and on mouse up, check if that property minus RealTimeSeconds is less than your tap difference.

[broken lichen]

Does anyone know how to make a cast from one widget to another successfully?

[shrewd oar]

I Need on mouse click to happens once but its continues :\

[mossy mist]

is there an on overlap event(or a way to create one)?

On Begin Overlap does not get called when actors are spawned inside it.
I also cant use get overlapping components/actors at tick because i want to detect instanced static meshes and those do not return the other body index like On Begin Overlap does.
I need a overlap function that always gets called, not just on begin overlap.

[maiden wadi]

Casting does not "get" an object or go to an object. Casting is just changing a pointer's type. To have one widget access another, they need to be able to find one another in your hierarchy somehow. This is often done for things like a parent container creating a bunch of child widgets and saving references to them.

[thin panther]

Yeah it can basically turn a general actor into a specific one

[trim matrix]

(unreal 5) im trying to get the player's world position here, but I dont know what to connect to "In Element Handle"

[trim matrix]

ayo bro this helped alot ty

[odd ember]

I have no idea what you're doing here, but if you want the player's world position, it's jut GetActorLocation on the player

[trim matrix]

ok Ill try that instead

lol

[thin panther]

Its important to note the taegt on these

[broken lichen]

So how would you play a widget animation when interacting with another widget

[thin panther]

For getting an actors location, is the target of actor or typed element world interface more likely

[thin panther]

I manage to hold references to all wodgets by making them in a hud class

It helps if your ui stuff is all contained in the same place

[mental trellis]

I think that's kinda the intended pattern. Lyra does it, doesn't it?

[thin panther]

Not sure with lyra but it is a standard practice

Just not many places mentioj that

A lot of unreal content just makes widgets whereever

Which sounds like this issue

Whereas if all widgets were made in the same place its very easy pointer management

[dark crow]

I remember before knowing the HUD class existed and what it was used for, I would store all my Widgets in the GameInstance for a easy global accessor
But yeah, HUD makes more sense for organization sake

[mental trellis]

A lot of unreal content/tutorials/games/professional devs are horrendous

[maiden wadi]

There's also no easy way to answer that question. Making one widget do something when something in another one happens has a lot of considerations about how those two widgets are connected. If they're even connected. Why that animation needs to be played, etc.

EG:

1. Put a binding in one widget and bind it in the one with the animation. Call it when needed.
2. Reference one widget in HUD. GetHUD in the other widget when doing something and hae HUD call the other widget to play the animation.
3. Bind a delegate in HUD. Call that from the widget doing something, bind it in the widget with the animation and play it when that delegate fires.
4. Don't actually have another widget ready. Make a HUD call to spawn a new widget for the animation that kills itself when finished.

@thin panther sorry to bother you AGAIN but I’ve got a lot done like obsticals and shit but no score or coins yet but the basics are done 😄

[thin panther]

Thats great!

[faint pasture]

We need a sticky or something on that, see that every single day.

[thin panther]

Coins are quite easy

[trim matrix]

Indeed

[trim matrix]

Should I make them in blender or no?

[thin panther]

Tbf i dont think the newbies check the pins first

[thin panther]

Since this is just a prototype project you can just use squished cylinders

[faint pasture]

At least then we could just tell them to rtfm instead of having to re explain casting for the 12th time daily

[trim matrix]

K

[thin panther]

Color em yellow with a mat

[trim matrix]

Oki

[thin panther]

Actually fair enough

[trim matrix]

Ima see a thing Hol up

@thin panther here is what I got so far

Map b shit ain’t done but

The gray and the cylinder kill you

[thin cradle]

might wanna use shareX or something to directly record the screen

[pulsar path]

is this something i should worry about? the UI just says its a note, but i want to be sure ive never gotten one of these notes before
the system im making isnt completed yet, so maybe thats the problem? it just doesnt have full context so it thinks i dont need to do what im doing?

idk what expanding start buff is

[trim matrix]

i have a recording software cant be assed to open it

so i used my phonr

[faint pasture]

Do you know what casting is?

That's like asking "Is MyDog an Animal?" You already know that.

You'd need casting if you were asking "Is MyAnimal a Dog?"

[pulsar path]

i know what casting is

[faint pasture]

You don't need to cast TestBuff to Actor since you already know it is an Actor since Testbuff is a subclass of Actor.

[pulsar path]

ah

[faint pasture]

Doesn't hurt but is unnecessary

[pulsar path]

so i wont have anything to worry about then, it'll prob go away once it realizes there will be multiple children classes to cast to

[faint pasture]

It looks like you're casting to Actor which will always succeed...

So why do it

[timber cloak]

This happens to be an issue to me often. If i don't cast it, it forces me to cast it too.

[pulsar path]

im casting to the class called Test Buff, which at the moment is hard coded to Test Buff for testing purposes, but will be actually casting to different Child Classes of Test Buff soon enough

[faint pasture]

@pulsar pathShow the StartBuff logic

[pulsar path]

im not gonna explain everythin, its not even finished i just wanted to know if the note was important since i didnt fully understand it

[thin panther]

just screenshot it

[faint pasture]

Let us see what you're doing, maybe it is, maybe it isn't

[thin panther]

the actual cast

it might be important but its impossible to know without context

i wasnt replying to you

[pulsar path]

do with that as you will

[faint pasture]

What is the type of that input?

The function parameter

If it's Testbuff then the cast is totally redundant. Only a TestBuff can be passed in

[pulsar path]

just Actor

[faint pasture]

dafuq

oh ok yeah

[pulsar path]

it makes sense in my head, i dont think it will be a problem

[faint pasture]

so thats not a function, thats a macro?

ok so the cast is unnecessary because it's ONLY ever gonna get the output of spawnActor Test Buff Child

[pulsar path]

yeah its a macro, i need the delay and the code will be repeated a bunch later

[trim matrix]

E I’m doing the coins rn

[barren sonnet]

Anyone have any good ideas of how I can fill a spline shape with paint an area in the terrain ?

[trim matrix]

What should the coins be used for?

[faint pasture]

Whatever you want

Collect them

shoot them

eat them

stick them places

[trim matrix]

Lol

Upgrades?

Hm

Maybe later

[faint pasture]

It's your project bb, just do whatever you want.

[trim matrix]

Bb?

[faint pasture]

yup

[trim matrix]

Idk what that means?

I’m dum with 3 brain sells

[odd ember]

I hear that in real life you can use coins to buy stuff with

not sure if that's true

[trim matrix]

I hear that too

Omg

Coin pickup work

:ooo

That took me about an arour lol

[scenic kindle]

does random unit vector also give negative values or just positive values between 0 and 1?

[royal trellis]

QUESTION: Is there any way to drive trucks in Matrix City project? I Tried to figure it out but not able to solve it.

[faint pasture]

Negative too I'm pretty sure

It's a sphere of vectors of length 1

not sure if the distribution is correct but it'll work

[scenic kindle]

ok thanks just wondering

[trim matrix]

uh oh guys

...

i fixed it

[deft nimbus]

Did anyone ever have the problem that a hit event doesn't get triggered? Hit events are enabled on both components

[trim matrix]

No

I never have

[earnest tangle]

There are some other things which can affect this. Both have to be blocking, if you use crowd avoidance this may push things apart to not hit, some other cases maybe as well

[spark steppe]

both have to be blocking on the other actors channel^^

[deft nimbus]

I'll have another look but I'm sure I checked that

It's weird because they physically interact with each other

[cobalt gulch]

What do i put in object for my in game hud

[thin panther]

get hud

that is if that is a hud class and not a widget

[cobalt gulch]

Its a widget

[thin panther]

then you need a reference to the widget

casting isnt magic

it doesnt find an object

it just changes a type

like changing and integer to a string, the stuff inside doesnt change

just means you can do different thing

#blueprint message

[cobalt gulch]

I referenced the widget

[thin panther]

then plug it in

look at the link i posted

it explains what a cast is

[cobalt gulch]

hm

how can i find the specific object?

[thin panther]

you should have saved it when creating the widget

it is reasons like this why widgets are all generally created in the same place

like subclass of hud bp

put everything in there

pause menu, all of it

hell put it in some functions and save the reference

[cobalt gulch]

im just trying to reference the part of the widget

[thin panther]

that way to access all of your widget logic you can just do get hud > cast to hud > whatever widget func you need

[cobalt gulch]

through the player character

[thin panther]

yes this is your issue

you cant do that without it's pointer

and you havent saved it's pointer

so you cant get it

[cobalt gulch]

wat

[thin panther]

right no object instantly knows where the other is

it has to have something tell it

[cobalt gulch]

oh wait i see now

i need to create a variable for the widget so i can reference

[thin panther]

when you make widgets in any ol place, other bp's dont know about em

[thin panther]

yes but thats only part of the point im trying to make

normally so we can get a central store of things, we group things together, like putting all ui stuff in the hud, which makes it easy to get later

its kind of like

imagine in your kitchen you have various drawers and cupboards

[cobalt gulch]

I see

[thin panther]

when you buy things they have their own place

like the bread gets but with the other bread

the frozen food gets put in the freezer

the cans get grouped together

that way you know where they are...

the method that is quite commonly (wrongly) used and taught in tutorials is to stick things anywhere, so it's like having some frozen food with the bread, a couple of tins in the freezer, storing the soda in a bag

anf then everythings confusing

you have to go hunting for it < represents get all actors of class

or if you organize it, you can go straight there < represents get hud > cast to hud

it also helps why get all actors of class can be expensive

[cobalt gulch]

Where should i put it

[thin panther]

in large levels, thats a lot of stuff to go through

[cobalt gulch]

I have put the code in the visibility of the element

[thin panther]

thats a binding on a widget?

[cobalt gulch]

But it wont trigger

Yeah

[thin panther]

...did you read any of what i just wrote

[cobalt gulch]

yeah

[thin panther]

have another read through it

[cobalt gulch]

but i put the bread in the bread bin?

where it should be

[thin panther]

you didnt

[cobalt gulch]

is this talking about the main events page with the construct event

[thin panther]

putting the bread in the bread bin, would be grouping all widgets into one easily to reach place

no this is talking about bp's in general

this is a bit more work for now, but will be smooth sailing down the line trust me

better to get the good practices now rather than later

[cobalt gulch]

True

[thin panther]

i'll draw ya a little diagram

ya see how that works nicely

you have all your widget creation and stuff in the hud bp, as well as saving the references there

then wherever else you need them you can just do > get hud > cast to hud > get widget ref/do function for something

[dawn topaz]

what is the name of this node? I'm trying to follow a tutorial for a double tap action, but "Inputs" doesn't pull up anything

[earnest tangle]

Looks like a custom macro to me

[molten musk]

Anyone ever seen this error before? It is a Blueprint instance of ModMagnitudeCalc. I can't get the tags from spec because "self" is a read only target in this case. Same error with the GetCapturedAttributeMagnitude Node

[dawn topaz]

Sorry, that was a stupid question
I looked at the image example again, and they have Inputs/Outputs just like a Macro (I'm pretty much a day one user, so I've never hit "New Macro" before)
Thank you

[earnest tangle]

@molten musk The function you're working on is const, and the nodes you're trying to call are non-const, therefore it won't let you

[dawn topaz]

I'm sorry, I'm confused again
I assume this is what it looks like outside of the macro, but I don't understand how to make the InputAction plug into the Inputs for the macro

[earnest tangle]

Those are collapsed graphs in the screenshot and not macros, but either way with macros you need to add Exec pins as parameters for it

[dawn topaz]

oh, then I guess I don't need to make a macro

[earnest tangle]

Yeah if you have a graph you can just select the nodes you want to collapse, and right click and choose collapse from the menu

(you can also do that to create macros from sets of nodes)

[dawn topaz]

how do I make this have a Pressed/Released Exec(?) output?

[molten musk]

@earnest tangle Agreed here is an example of the function being implemented in c++ and you can see it is a const function. I was hoping there might be some blueprint trickery to have those nodes treated as const. They are "getters" after all. lol Thank you for your response!

[dawn topaz]

I want to be able to double tap A or D to sidestep

or should i use the keyboard events instead

[earnest tangle]

you would have to make it an input action and not an input axis, but I don't know how well that would work for movement axis stuff
