when aiming up and down it doesn't work properly

when aiming left to right it works

[trim matrix]

now i can only press w once when i press it goes 1 down and when i releasd w it goes up again and nothing with s

[blissful widget]

What's the graph looking like?

[blissful widget]

Looks right, except for the add. You need to add the current elevation to it

[trim matrix]

how i do that

[blissful widget]

Connect the current elevation to the pin that's set to 0 here

[trim matrix]

what should i set it to

[blissful widget]

Current "Gun Elevation Angle"

[trim matrix]

i dont get it

[trim matrix]

it is 0

[blissful widget]

It won't be 0 after you've added to it though. The point is to add to the current angle, and keep adding to it instead of just setting it to 0.1 and that's that

[manic adder]

hello. how can i set up a camera to do a 360 rotation around a given point ?

[lucid lynx]

Put the camera on an arm then rotate the arm.

[limber parcel]

https://tenor.com/view/calculation-math-hangover-allen-zach-galifianakis-gif-6219070

[blissful widget]

There's a pin with a raw value, currently 0. That needs to be getting Gun Elevation Angle. To get its value, you need a getter, which would be a function node like Get Gun Elevation Angle.

[lucid lynx]

How would I get the dot product of an actor based on their velocity rather than their facing? I want to determine if they're moving towards something, not that they're facing it.

[blissful widget]

I think you'd be much better off watching a few BP tutorials to get the general idea as well, if you know some programming already

[blissful widget]

Get Last Update Velocity on Character Movement Component

[trim matrix]

uhm im sorry man i just dont get it

[lucid lynx]

I'm not sure what to do with that, though. I'm spoiled by GetHorizontalDotProductTo. 😅

[limber parcel]

whats a dot product? xD

[trim matrix]

what is a getter

[lucid lynx]

If two actors are facing each other it's a 1, if they're facing away from each other it's a 0, if they're kinda in between it's a 0.5.

[blissful widget]

A function that returns the value of a variable

[manic adder]

most tutorials, even the documentation, handle with players etc, i just need a camera that i can render in a sequencer. do i need to make a bp, reference an existinga camera etc or is there a simpler way ?

[limber parcel]

ohh that sounds useful, thx

[blissful widget]

This is what that node does

[gentle urchin]

Basically how alike they are

[gentle urchin]

@limber parcel 1 being identical, -1 being opposit

[limber parcel]

so its 1 if they face same direction?

[gentle urchin]

Yes

[trim matrix]

so i need to make a function called Get Gun Elevation Angle

and put it to the 0 value and then what

[gentle urchin]

0 would be perpendicular

[blissful widget]

NO it needs to return the value of the Gun Elevation Angle variable

You're not trying to set it to a static value, rather change its current value upwards or downwards, IE you need its current value, then you add an offset to its current value, and then you set that to be its new value.

[blissful widget]

There's a dedicated dot Node that just takes in two vectors
https://www.youtube.com/watch?v=-r-ahrPQrLU

One input would be the last update velocity, the other would be... well, you decide. The other actor's last update velocity?

[trim matrix]

okay uhm

[cedar remnant]

Good morning! I'm reposting for morning so I can get more eyes.
I am trying to find a way to remap the controller Dead Zone settings using the Enhanced Input Action system. My goal is to expose the lower and upper threshold as variables I can access through UI. Any idea on this or know of anyone who may know?

[mental trellis]

Why not just access them directly from your UI?

Why do you need the intermediate variable?

[cedar remnant]

Either works. I am just unable to access them either way

[mental trellis]

Unable to access them because?

Is EI stuff not exposed to BP?

[visual crest]

UE5 crashed and I lost a interface I remade it but now when I try to add that interface as a call action I get this. How do I fix?

[cedar remnant]

I'm not definitively sure if it is or not. I haven't been able to retrieve it so far. That was my question I guess

[manic adder]

how can i animate a camera rotation around a fixed point while skipping all the game/player-realted stuff while i work on a render export ?

[limber parcel]

put another actor at that point, attach a camera to it with an offset and then rotate that actor

[mental trellis]

Your render is a "game" so you can't skip the "game" stuff.

[limber parcel]

https://tenor.com/view/mind-blown-amazed-explosion-space-omg-gif-10279314

[cedar remnant]

I have this variable which contains my mapping context shown here. I'm just really unsure as to how to actually dig down and pull out that setting

[mental trellis]

Your rotating camera would either be controlled by the "game" or a level sequence

[manic adder]

a sequence, thank you

[manic adder]

thanks

[cedar remnant]

There is "map key" which is fine for rebinding but doesn't offer me access into the 'Modifiers' inside my mapping context.

[visual crest]

MY Blueprint is referencing a interface that was lost in a crash I removed all interactions with it but is still will not compile

[blissful widget]

Go to class settings and look at what interfaces it implements

[limber parcel]

and dont forget to point ur camera at the rotating actor

[limber parcel]

add and remove that interface again if it doesnt work

[visual crest]

ok

[trim matrix]

@blissful widget pls dont be mad im just asking

how do i make a getter😬

[blissful widget]

It's a function that returns the value of a variable.

[gentle urchin]

1 mississippi, 2 mississippi, 3 mississippi... 🙉

[gentle urchin]

Its an alternative to allowing direct access to variables from derived or external classes

So instead of just grabbing the health variable or whatever, youd make an explicit public function to GetCurrentHealth , which simply returns the value of the variable

[trim matrix]

i try make one is it hard to make one? or simple

[gentle urchin]

Very simple

[trim matrix]

can you teach me

[gentle urchin]

The most basic function you can make

[trim matrix]

i feel dumb now

[gentle urchin]

Create a function

Drag in the variable into the function graph

Right click the graph and add a Return Node

Drag from the variable onto the return node

While the return or entry node is selected , in the details panels, mark it as "pure"

[trim matrix]

like this?

[gentle urchin]

Almost

But instead of set

You should "get"

Get GunElevationAngle

[gentle urchin]

Remember , we want to read the value, not modify it

Now connect the variable

[trim matrix]

do i need to do something to make it only read

[gentle urchin]

To the output

"Get" reads

[trim matrix]

ahhhhh

[gentle urchin]

"Set" writes

[trim matrix]

now i need it in the other bp

[gentle urchin]

Show the result first

[blissful widget]

You really want to watch some BP tutorials to get hang of the basics IMO

Like this stuff is covered in heaps of tutorials, we're just typing up BP 101 for you ATM

[gentle urchin]

Yeah theres many pitfalls and issues thats on its way towards you if you dont understand how things work

[trim matrix]

sorry

[gentle urchin]

Tbf many tuts should practice better public and private variables and functions, and how to safely set values and whatnot

Atleast thats the case when i watched 'em many moons ago

Casting from here to there, allowing any other actor to modify any variable in some random bp is not a good idea

[blissful widget]

They just create a new project for each tutorial, unless it's a series. The code is 100% throwaway, almost by design

[trim matrix]

then how i do it

[fallen glade]

Are there animation libraries? like blueprint macro/function libraries?

[blissful widget]

Personally I'd rather just a straightforward tutorial than an 'architected' one. I'm going to redo everything about it anyway, I'm just there to understand the idea behind it, rather than learn someone's implementation details.

I've got a software background so I just hate everyone else's programming style. It's in my nature at this point

[gentle urchin]

From a firmware background, i share this view 😅

I try to always improve my own setups

[blissful widget]

The one thing that annoys me is when BP tutorial makers apparently forget about functions, collapsed nodes, events, and just any BP organisation method. Readability is important, and actually speeds up tutorials if you have to pan around the editor less

[gentle urchin]

Plus the mind can only cope with like 7 variables at the time,

So these massive functions become incomprehensible if not divided and structured with sub functions etc

[visual crest]

Is there a way to convert this node into any pawn currently controlled by players?

[dawn gazelle]

Cast to pawn?

[visual crest]

ok Ill try

Thanks that worked!!

Does doing that have any down sides? like cost more processing power or something?

[dawn gazelle]

It looks like you're using an interface right after it tho... It's not really necessary to cast if you're using an interface call.

If anything casting to pawn is better than casting to ThirdPersonCharacter as it's a lighter class

[visual crest]

ok thanks Ill need to go to all my BP and change it to pawn

[dawn gazelle]

I wouldn't do that.... Sometimes you need the reference to be at ThirdPersonCharacter if you need to access variables and functions that you've set up in ThirdPersonCharacter.

[alpine ingot]

Hey I thought this is gonna be simple but got stuck with it. Is it possible to write the output log to the running game's screen? How do you even read the output log from blueprint or cpp?

Should I just read the actual log file?

[visual crest]

I know but if I change pawn or have multiple players I have to have it pawn... I just have to add thoes functions to all my pawns

[visual crest]

Why is this not compatible?

[tight schooner]

@visual crest try casting to "BP My Charactor"

A cast is a class check

If it passes the check, it transforms the reference into that class

You were casting to the pawn class, and trying to feed that pawn reference to your "BP My Charactor" variable

So yeah, not the right data type

[visual crest]

I am trying to make a controller for all player pawns

how do I do that?

any ti

any time I try to use jump it always says not compatible

[tight schooner]

Is jump a function/event? The node should say "target is..." such and such

So it'll only work on a target of that type

Anyway you can look into how controllers possess pawns

It's kind of weird for a controller class to be directly telling a pawn to jump

Usually a pawn, when possessed, will listen for the jump input (see project settings — inputs) and handle that itself

And the controller does universal stuff, like handle the action for opening the game menu

That's kind of all I can say cuz I never made a multiple pawn game before

[visual crest]

ok I get it the controller is not the player controller per say but the interface controler

Thanks Ill watch a tut or two more on it

[tight schooner]

If you need one BP to talk to other BPs of different classes, you need to learn about interfaces and class inheritance

Otherwise you end up casting to every type of thing in your game

[visual crest]

I learned that too day 🙂

GTG thanks for the help

[tight schooner]

You can cast to a parent class and call a parent function, and that'll work for all of its child classes for example

np

[trim matrix]

How to stack function calls

Like how can I add the same function more than once

Use the same function multiple times, how to link them

[obtuse geyser]

Hello I need some help, so I made an Array of anim montages, and I'm playing them on my keyboard keys as you can see on my screenshot

But I want to make it stop playing whenever I'm moving my character
Could someone of you help me construct blueprint to detect player movement, and if so to stop playing Anim Montage? I would appreciate

[rapid robin]

Hey all. Is it possible to set up a Sequencer camera, and trigger it to do a screenshot in blueprints?

[neon forge]

Is there a way to bypass a Layered Blend per Bone node when I play an anim montage from a bp? I have a bp set up to trigger an animation (kneeling down to pick something up) and only the top half of the animation plays on the skeleton.

The blend per bone is used in conjunction with the Document Reader Pro asset on the marketplace.

[icy dragon]

Slots.

[neon forge]

slots in the Blender per Bone?

[icy dragon]

After the layered blend

[ornate trail]

how can you make a character nose dive when jumping off something high up. Basically not sure how to orient him as the gravity always makes him straight up and down.

tried set / add rotation but doesn't see to work.

[loud cipher]

I have created a simple dismemberment system that checks a list of broken bones already, it checks if the hit bone is already in the list of broken bones, if not, then hides the bone and spawns in a static mesh version

But i have craeted a branch inbetween because if i shoot the upper arm l, it only spawns the upper arm l, disregarding its lower arm l and hand l

hiding them without spawning them in

I am really stuck on how to get it to recognise the child bones and spawn them in

i got up to finding the parent bone, checking if it is in the list of broken bones

[bitter ingot]

trying to load a level but the volume simply doesnt trigger the level what should i do???

tho it works if i use the blueprint node "Load Stream Level"

[faint pasture]

You'd have an UpperBodySlot and FullBodySlot

anything you play on UpperBodySlot is before the blend, put FullBodySlot AFTER the blend.

[blissful widget]

Anyone have a clue WTF is going on? Character is oriented to movement, but sways really fucking weirdly during movement. Jump is wacky as fuck too

[faint pasture]

Show the rest of the error

[trim matrix]

why the script not working

[faint pasture]

make the capsule visible

[faint pasture]

Show the rest of the error

[blissful widget]

Rendering > Visible? Already on

[faint pasture]

With your animation, NOT by reorienting the capsule

[gentle urchin]

Custom movement mode

[faint pasture]

hidden in game

[gentle urchin]

Or that i guess

[faint pasture]

You could reorient the capsule but that gets much fancier

[gentle urchin]

Probably more correct 😄

[blissful widget]

The particles (if visible), trigger when the landed event is fired, but the jump is still broken, among other things haha

[neon forge]

That worked! How does UE4 recognize what slot is what? Like one is named Full Body, one is Upper body, how is UE4 recognizing what is what? Does it work like that? Or is it more it's cancelling the blend bone by using that slot and it doesn't necessarily matter what the name is? (hope that question made sense)

[gentle urchin]

Name doesnt matter beyond your practical use of it

Its struct has a bone name which it will affect all the child bones to, iirc

[neon forge]

ah, okay. Thank you 🙂

[gentle urchin]

So you usually divide them into whats practical, upper/lower body, head etc

[blissful widget]

Alright I figured out my issue, the weapon I re-created seemed to be blocking the pawn's movement and pushing it away? Have to remember what I had it set to

[gentle urchin]

All the things to be mindfull of

Damn weapon 😅

[blissful widget]

I had to mass re-create BPs because I did a C++ no-no, and just squashing bugs from my shaky data entry haha

[shrewd abyss]

is it possible to create a mesh volume that culls a specific actor BP when you step inside of it?

[tawdry surge]

on overlap-> actor has tag-> destroy actor

[shrewd abyss]

ok good

[trim matrix]

Im not getting any red errors anymore

But the script isn’t working

I Just want it to continually add force

[tawdry surge]

Your adding 5 force (basically nothing) at the origin of the world it looks like

[trim matrix]

How do I add it relative to the box

[trim matrix]

Also that should generate torque but it doesn’t

[tawdry surge]

Just give it the box's location

Pretty sure torque is a different function

[trim matrix]

No

Add force at position is supposed to generate torque and force

It’s not doing anything

[shrewd abyss]

is there a way to do that within the blueprint of the mesh volume? so that i dont need to make a new level BP for every possible trigger created?

[azure smelt]

I set up some IK for a VR player awhile ago and it was working great. Now I have returned to the project and for some unknown reason the walking animations aren't blending. I don't know why, can some please help? I'd really appreciate it

[tawdry surge]

@shrewd abyss same nodes

[zealous moth]

I am trying to make an updatable list in UMG but I am getting way too confused...
I have a map of an enum and int. Basically, count X things.
When I pick up a coin, it triggers adding the item base umg but it never updates the values to the right texture nor number. Error states "accessed none" but I cannot fathom why..

[shrewd abyss]

okay but i cant reference the BP i want to cull in the event graph of the volume BP

sorry im not great with BP im mainly an artist

[gentle urchin]

Show some code

[zealous moth]

base item:

list

base item design

[gentle urchin]

Damn, actual list view

[zealous moth]

😄

I figured i didn't want a static UMG for score

just add stuff and if i want more, i update my Datatable

[gentle urchin]

Id just do scrollbox

[zealous moth]

if i pickup 3 coins i get this

[gentle urchin]

Dont need such optimization 😅

[zealous moth]

I did this once before

and it worked

no idea what i am doing wrong

here's errors

for each coin 2 errors

so there is a none value in the "on added"

but i don't understand why it is none

should be something

[tawdry surge]

@shrewd abysson overlap will give you the overlapping actor. You can check class or use has tag to filter out which actors to destroy

[trim matrix]

Dude

@tawdry surge do you know what is wrong with my script

https://media.discordapp.net/attachments/221798862938046464/999710306446094436/unknown.png

[tawdry surge]

My guess was you aren't setting the right location

[trim matrix]

It should still be moving even if it’s the wrong location

@tawdry surge

Like it should be spinning

None of that

[gentle urchin]

Are you sure the incoming object is valid?

[zealous moth]

should be since it loads the default values

it's the changing of the values that isn't working

this was a game about stickers

the unit ^

and the list:

[shrewd abyss]

yeah im sorry i have no clue how to do this

[faint pasture]

You're adding force, but pretty much 0 of it

[shrewd abyss]

idk how to give something a tag

[faint pasture]

0.5 is a TINY TINY force

Unreal units of force are centinewtons

that's like half a gram

half a gram isn't gonna move much

[tawdry surge]

@trim matrix Works for me

[zealous moth]

tiny
Hey man, it's the not size that matters, it's the relative magnitude and direction in relation to momentum

[mental trellis]

Momentum is irrelevant, as everything is relative.

[tawdry surge]

barely moves at 5000 tho

[mental trellis]

The same force will produce the same acceleration regardless of momentum.

[faint pasture]

5000 isn't even that much

Wait till you add a torque

[tawdry surge]

I'm just saying 5 doesnt do anything cuz it's like a weak breeze

[zealous moth]

@faint pasture i wish the values weren't in the millions

[faint pasture]

I deal with torques on the order of 400M - 2 Billion

Torque units are centinewton x centimeter so 1/10,000 of a Newton-meter

[tawdry surge]

that's based on mass tho right? so scaling down mass should allow you to use lower values of force and torque

[trim matrix]

Ok so if I set it to 1000 it should spin?

[faint pasture]

Set it to 100k and dial it back from there. We don't know the mass or moment of inertia of the thing you're trying to spin

[trim matrix]

Default values

[faint pasture]

If you're just trying to spin tho add torque. The non-location ones can ignore mass and directly affect acceleration

[shrewd abyss]

like every node im finding relating to getting stuff with a tag wont go into the destroy actor node

[faint pasture]

That doesn't help at all

is it a ship or a fly

default mass depends on volume and density and mass scaling which are all on the physical material.

[tawdry surge]

@shrewd abyssYou'll have to add the tag on the actor you want to be destroyed and then set the has actor has tag node to look for it

[trim matrix]

A cube

[zealous moth]

@gentle urchin so i did a test with print string on event construct.
I have default values in the unit at the designer level and at the variables level.
The output is the default designer values.
The print string shows the defaults for the variables.

So there is no communication anywhere ~_~

[faint pasture]

Is the cube the size of a battleship or a pebble?

just set the mass

god damn

[trim matrix]

It’s default size from primitive objects stack

[gentle urchin]

rip! Damn list view 😄

[tawdry surge]

I think default is like 100kg

[gentle urchin]

gonna make a mockup.. give me a sec...

[zealous moth]

turns out i used the Get functions from umg

[gentle urchin]

kiddo is not asleep yet

[zealous moth]

and that works

[gentle urchin]

Oh, you solved it ?

damn

well done 😛

[zealous moth]

no

it's crap

[gentle urchin]

oh xD

[zealous moth]

the overrides that takes in the umg every tick

that was my bandaid

terrible solution

[tawdry surge]

@faint pasture torque in radians also works with much lower numbers than degrees, which makes sense

[zealous moth]

so the order of operations when the widget unit is made is that it is constructed first and then added to the list

[neon forge]

So would I need a slot for each individual anim-montage in the anim-bp and reference that after the the bone blend, Or will creating one reference that automatically?

[gentle urchin]

Im not very versed with it, but i usually only create a few slots and re-use them

[zealous moth]

this works

[faint pasture]

I'm fairly certain the radians/degrees only comes into play if you ignore mass but I'm not sure. It'd make sense for it to do it that way because torque doesn't HAVE an angle unit.

[gentle urchin]

So it was a race condition

sorta

[zealous moth]

not quite, i was just pointing it out. No matter what order you use, it has to be AFTER the event on list item object is set

[gentle urchin]

right, but doesnt that qualify as a race condition 😛

anyways

hows the performance going now then ?

[azure smelt]

I set up some IK for a VR player awhile ago and it was working great. Now I have returned to the project and for some unknown reason the walking animations aren't blending. I don't know why, can some please help? I'd really appreciate it

[trim matrix]

how to get reference to object location

[zealous moth]

i mean it is super optimal i just want to have this event only happen when i pick stuff up rather than on tick

[gentle urchin]

right, for sure

how many items are you planning to have in game?

[zealous moth]

10

maybe more

[gentle urchin]

😛

ok

surprisingly few for such an optimal list

[tawdry surge]

get actor location or get world location if you wanna reference the static mesh spacifically

[zealous moth]

So here I have 3 points:
1 - After the item is added
2 - I cast inside my item added
3 - I set it as a reference.

From here I should be able to set the values

this was used to run on tick

and that works

[hexed jungle]

Is it possible to have base scalability overrides in a packaged project?

I need r.SceneColorFormat to never go beyond setting 3.

[trim matrix]

how can change it so its in newtons and metres

[faint pasture]

multiply by 10,000

100 Unreal Force = 1 N
10,000 Unreal Torque = 1 N*m

[trim matrix]

that is ridiculous

why is it centinewtons instead of newtons

[faint pasture]

Well it's because the unit of length in Unreal is the cm, not the meter

look at your gravity constant. It's -980

unit of mass is kg, so force is kg*cm/s^2 or centiNewton

since force is centiNewton and length is centimeter, torque is centiNewton*cm

[trim matrix]

how can change the keybind for the blueprint editor

want to change grab to middle mouse

[faint pasture]

If you don't like the units, go talk to Tim Sweeney. And while you're at it, get the axis setup fixed.

[trim matrix]

wat

#blueprint message

[humble sleet]

so, question

I'm trying to make a menu system

[gentle urchin]

So you have to keep around an object for every item in the list ?

[trim matrix]

duplicate is ctrl w

[zealous moth]

yeah

[trim matrix]

wth is wrong with the keybinds

[gentle urchin]

Sounds troublesome

[humble sleet]

is this a valid way of doing things? I haven't a clue what I'm doing with event dispatchers

DoThing is just an empty function in the menu pawn

[faint pasture]

That's kinda gross, what's the use case?

[humble sleet]

idk

[faint pasture]

What are you trying to have happen

[humble sleet]

I'm honestly not sure, I'm trying to follow 2 different tutorials at the same time concerning a menu, and one of them uses a specific pawn for the main menu

[faint pasture]

Is this just like the opening screen?

[humble sleet]

yeah

I get the feeling I don't need to do a lot of what I've done

but at the same time it doesn't quite feel right to not do it

[faint pasture]

Just create the widget and add to viewport from wherever if you want

[humble sleet]

ok

[gentle urchin]

Keep the maps and modes separated imo

[humble sleet]

so what is the point of the Create Event node?

[gentle urchin]

It's handy for sure,

but not for this

[faint pasture]

if you want to have the same thing availible everywhere, like the same menu when you pause in game, I do that by making HUD stateful

[humble sleet]

you're gonna have to define stateful for me

[faint pasture]

State machine

[humble sleet]

ah

[faint pasture]

I have an enum in my HUD

[humble sleet]

yeah that would make sense

is there any point in having a specific pawn just for the main menu?

[faint pasture]

Switch on EHudState which can be MainMenu, Options, Gameplay, whatever, whatever

[gentle urchin]

statemachines can go into locks if you're not carefull 😛

anything can, i suppose

[faint pasture]

You need a specific something for the splash screen, but it depends on what your transition out looks like

we don't do a hard load at any time other than startup and joining multiplayer, so it's all the same gamemode, playercontroller, pawn, all that, the entire time from boot to exit

[shrewd abyss]

yeah i cant figure it out

[humble sleet]

is there a default pawn that gets loaded on start or can you be pawn-less?

[shrewd abyss]

i will try again later

[gentle urchin]

pawnless apparently

[faint pasture]

I think you can be pawnless but that can be more trouble than it's worth

[gentle urchin]

I didnt know that was possible, but apparently it is

for a main menu you usually dont need a pawn

[faint pasture]

AFAIK we are pawnless until spawning/loading a character (it's a roguelike)

but we directly control the player camera manager and don't use camera components

[humble sleet]

I'm just wondering if UE will just grab my main character as the default pawn or sth

[gentle urchin]

It wont

unlress you tell it to

[humble sleet]

ok

[faint pasture]

nah that's a variable on your gamemode

you have a default gamemode and also a level can override it

[faint pasture]

gamemode chooses your other classes

[humble sleet]

ahhh

[faint pasture]

Maps and Modes in project settings chooses the default maps and gamemode

[trim matrix]

how can i

[humble sleet]

yep, set default pawn class to none

[trim matrix]

input a float value

variable

[gentle urchin]

type it in one sentence ... so your question doesnt get broken up

[trim matrix]

how to add float variable node

[faint pasture]

That doesn't parse but if you're asking how you can create a float variable, then just make a variable of type float

click the plus

read the getting started with BP stuff

just mess around

[gentle urchin]

(psst; watch a tutorial)

[humble sleet]

so for a level select screen, how would you recommend doing the actual level loading? just have a bunch of 'open level' nodes directly in the widget?

[gentle urchin]

Depends on the amount , but thats the gist of it yes

At some point with most setups you reach a point where the overhead for creating a procedural system becomes worth it

if its 5 levels i'd never bother

but if its 500 (for some insane reason) then I'd definetly consider it

[humble sleet]

I'm interested in the procedural approach, what sort of thing do you mean?

or are you just gesticulating verbally

[zealous moth]

@gentle urchin so i missed a part in the designer that binds the output to a variable

I did that

[cedar crypt]

how do i fix this camera movement?

https://i.imgur.com/Jq5csvA.mp4

[zealous moth]

now it goes to the variables

[cedar crypt]

when looking up/down the weapon aims at an angle

[near wolf]

I have a blueprint with instance editable variables. But When I duplicate it in the world and try to do a change, it applies for both actors. What am I doing wrong?

[gentle urchin]

@humble sleet Well, you could make some function that searches for all the "maps" in a given folder, and for each map found, create a widget and add it to a level select container of some sort, which references the level it was given, either by name or index

As an example

[cedar crypt]

when i aim sideways it works fine

[near wolf]

I have this media source, where you input the source. I wanna have 2 actors with 2 different sources, but it doesn't work

[humble sleet]

ahh ok, that makes sense

I was definitely thinking about it the wrong way

[trim matrix]

i set this to a variable but now its acting as if its set to 0 when it isnt

[zealous moth]

FIXED IT

[gentle urchin]

For it to be set, a white line must be connected to it

otherwise it's not set

it acts as a normal get'er in this case

[humble sleet]

@trim matrix these need to be connected

[zealous moth]

@gentle urchin

THERE

stupid moth******* piece of ******

[gentle urchin]

This is getting better and better 😛

[zealous moth]

you set the variable OF THE OBJECT to the reference

absolutely assinine

[humble sleet]

back to this again, I presume by this you mean if I have a menu featuring my main character, with a smooth transition to player control

[gentle urchin]

all for the sake of using an absurdly optimized list for 10 items 😛

[zealous moth]

well, if i ever want to add different or more items, i can now 😛

[gentle urchin]

YEs, but this is made for thousands 😄

[humble sleet]

that's one way to do it, but if you select your Force variable in the details panel you can set a default value

[zealous moth]

I could have different pickups based on different levels

[gentle urchin]

thousands

anyway, when it work, it works 😛

[humble sleet]

down at the bottom

[trim matrix]

is this 3rd person player controller physics based?
because all the "Simulate Physics" toggles are off

[humble sleet]

it uses acceleration, friction and gravity, so yes to an extent

but that stuff is calculated in the Character Movement Component

[gentle urchin]

Thats one example of when you'd want the pawn in the main menu

[trim matrix]

is the character movement component physics based?

[humble sleet]

that depends on what you mean by 'physics based'

you can apply forces to the player character and it will act like a cube

except the capsule will stay upright

[gentle urchin]

unlesss custom movementmode

[humble sleet]

^

you can use the Set Velocity and Add Force nodes to the character and it will work as usual

[trim matrix]

because i get physics based reactions even with "simulate physics" on the mesh and capsule turned off

thats the player after colliding with the spinning cube

[humble sleet]

well the mesh doesn't matter IIRC

because it's a child of the capsule and is controlled by the animation blueprint

ok ok I guess I'm being annoying and dancing around the question, yes the character movement is physics-based in all the ways that will matter to you

you can use forces to move it around

[trim matrix]

Nicee

[humble sleet]

I've just found the tutorial that recommended using a 'Menu Pawn'

it seems he was using it to hold the menu widgets

I presume I can just stick that stuff in the menu level blueprint

[gentle urchin]

Or the playercontroller used in the menu

or the hud used in the menu

many options really 😛

[humble sleet]

that's what I hate

I want to be railroaded into the correct way, for once

[gentle urchin]

I'll let you in on a little secret

[humble sleet]

I have choice paralysis

[gentle urchin]

nearly anything can be done in a thousand ways

[gentle urchin]

Then this is not a great place to be 😛

Ask 3 people how to do one thing, and you'll get 3 different answers

[humble sleet]

call it immersion therapy

[trim matrix]

How can you change the method that is used to add forces to the rigidbody

[humble sleet]

wdym by 'method'

force is an acceleration over a time period

[gentle urchin]

write a custom physics component ?

[humble sleet]

what are you trying to achieve?

[trim matrix]

In unity there is a parameter called ForceMode that changes the effect AddForce() has on a rigidbody
When forcemode=VelocityChange it adds the value to the velocity, when forcemode=Force it takes into account the mass I think
And of course forcemode=impulse is impulse

[humble sleet]

ahhh yeah there's something like that in UE

it's a bool in one of the nodes

hol up, I'll have a look

[gentle urchin]

isnt that just different nodes here?

[humble sleet]

I definitely recall there being a 'velocity change' option

[trim matrix]

Ik there is add impulse and add force but idk about velocity change/acceleration

[trim matrix]

What about acceleration?

[humble sleet]

character movement components can't have their mass overridden

[gentle urchin]

in blueprints?

[humble sleet]

in blueprints

[gentle urchin]

it is atleast a parameter

guess its just blueprintReadOnly

[humble sleet]

I guess I meant to say that by default, the Add Force for character movement components doesn't have an Accel Change input

[gentle urchin]

ah

[humble sleet]

which explains why I was struggling to find it initially

and why @trim matrix may also have not been able to find it

[trim matrix]

Add force at location local

[humble sleet]

what effect are you trying to make?

[trim matrix]

Custom gravity

But without adjusting world gravity

[humble sleet]

I think you can set gravity strength per object

[cedar crypt]

https://github.com/HoussineMehnik/UE4-CustomGravityPlugin

[trim matrix]

What about direction

[cedar crypt]

that?

https://www.unrealengine.com/marketplace/en-US/product/directional-planet-gravity

[humble sleet]

custom directional gravity is harder to make in blueprints without some hacky fixes

especially if you're using the default character movement component

[trim matrix]

Like addforfe

Add force but acceleration

So it adds the same force to all objects independent of mass

[humble sleet]

yeah

[trim matrix]

Ah that’s why you were referring to mass overrides

[humble sleet]

check the Accel Change

but again, that node doesn't work for the default character movement

which is annoying

[trim matrix]

Oof

[humble sleet]

yes

[trim matrix]

Kekw

[humble sleet]

I saw the realization real-time

hoookay

I'm doing a turn-based game

bog-standard "let's all line up at opposite ends of a clearing and take turns hitting each other"

so I guess the player characters represented on screen can be completely disconnected from the actual player pawn

[remote stag]

Hello someone know what is wrong with this blueprint?

im removing a elements from array to get a unique actor every one loop body, but i dont know why im getting a duplications

[humble sleet]

ah

[gentle urchin]

Its because random

produces random

for each pin

this basically queries random 3 times

[humble sleet]

no, it's because the output pin of the Set node caches the initial value

[gentle urchin]

Nothing sets it

[gentle urchin]

You must cache the output from any random if you want to reliably use it

the array is set

not the random node

or random output

[humble sleet]

oh yeah

bruh

3head

[remote stag]

so i need to get new array when im removing elements?

[gentle urchin]

No,

[humble sleet]

hold on

[gentle urchin]

you simply must cache the found random

save it in a variable, temporarily

[trim matrix]

Ok but what has hat dot to do with velocity change no working

[gentle urchin]

Also,

[humble sleet]

that wasn't to do with your issue, that was my project

[trim matrix]

O

[remote stag]

Im setting a founded actors to BP Curse Item, then im removing founded item and getting random again from array without that elem

[gentle urchin]

you're not checking if the found item is already cursed, and that another one should be made cursed...
yepp, you're removing it alright

[humble sleet]

squiz

the elements are removed from the array

[gentle urchin]

Yepp

noticed

[humble sleet]

but surely since the output of the Set node is used

[gentle urchin]

i was to quick on the trigger there 😛

[humble sleet]

then doesn't that cache the initial value of the array, and not the updated version

[remote stag]

.

[humble sleet]

or does it update

[gentle urchin]

I believe it does work as it should

I believe the get side of a Set actually is a regular Get

[humble sleet]

ahh ok

[gentle urchin]

i could be wrong, but i believe so

[remote stag]

so i need to get every time variable after removing a item from variable?

[humble sleet]

probably not

but wouldn't hurt to use a get

would also reduce the number of node wires

[remote stag]

okay but where to place it?

[humble sleet]

directly next to whatever you're plugging it into

just use a bunch of them

[remote stag]

too many getting variables is good to preformance? just asking

[humble sleet]

I don't think it matters, might be wrong

[gentle urchin]

Tested, and i was correct

But i presonally also prefer to separate the Gets

avoids spaghetti 😄

[humble sleet]

very much this

[gentle urchin]

reroutes also affects performance

[humble sleet]

don't you mean spaGetti

[gentle urchin]

but you'll never notice

[humble sleet]

wat

[gentle urchin]

Still not caching the found one

so what is removed

is not what is added

[humble sleet]

right click on the output of the Random node

and promote to variable

[gentle urchin]

(or Get CursedItems(Output from Add as index))

but thats just messy

Aalso

Curse vs Cursed

has like 99% overlap

you've messed up on the one you remove from

[remote stag]

okay wait guys

[remote stag]

thats what i get before

look

BP_Curse_Item is a array with all elements
Cursed Items is a array with elements, that will be added in loop (thats are a CURSED CURSED elements)

[trim matrix]

https://forums.unrealengine.com/t/set-velocity-on-character-movement/28143

[gentle urchin]

replace string array with your array

and your naming convention

[trim matrix]

referencing this will changing the velocity of a physics object directly break its physics calculations?

[remote stag]

gimme sec

[gentle urchin]

the important part is how I cache the output from the Random node

[humble sleet]

you're adding your random elements to an array, then immediately removing them

[trim matrix]

if you directly change the velocity of a rigidbopdy

[humble sleet]

no

it just overrides its previous velocity

[trim matrix]

so it doesnt break the phsycs?

[humble sleet]

define 'break'

[trim matrix]

uh

idk

[humble sleet]

you won't break it, don't worry

[dry condor]

depends on the value i would say, if you make the value too high something might start "breaking"

[humble sleet]

true

[trim matrix]

i just read somewhere that messing with the velocity directly is bad pracitce

[humble sleet]

potentially

but it depends on what you're trying to achieve

[trim matrix]

but there is no alternative here except writing a player controller from scratch

[humble sleet]

ideally a gravity system would work in a physically-accurate way and you'd apply acceleration using the inverse square law

so I guess in that sense, directly overriding the velocity is a hacky solution and thus not best practice

[humble sleet]

pretty much unfortunately

[remote stag]

Worked thanks, but why i need to Set to TempRandom?

[gentle urchin]

Whenever you get something from a random node, it will find a new random

[humble sleet]

it doesn't store the output in the output pin

[gentle urchin]

you can test this easily by doing 2 print strings after each other, and a random int in range

[remote stag]

So there will be a 2 separate random items?

[humble sleet]

ye

[remote stag]

gotcha, thanks! :D

[gentle urchin]

1 random for each wire 😛

so on your original screenshot, 3 randoms

[cedar crypt]

cool

i got my leaning system to work

[humble sleet]

gah

head hurt

[dim tapir]

Team, I'm trying to get a melee combat system going but it deals damage multiple times to a single enemy. I don't understand why it's not working. Any ideas?

[gentle urchin]

Same. Trying to slice up a procedural set of ISM's ... a pain

[humble sleet]

I'm just trying to figure out how to set up a turn-based game

[gentle urchin]

Manager, interface

what else is there ? 😄

[humble sleet]

I don't even know what I would use a manager for

as in, what do I put in the manager, and what in the game mode

choice paralysis

[gentle urchin]

Manager would be in the GameState (or be the gamestate)

[willow pike]

Working on an inventory system and have a question. Is it better to use a line trace to interact with items or would a collision box/overlap event be better?

[gentle urchin]

"better" is arguable

Linetrace requires accuracy

collision volume can show the closest to center item as interactable (with a given treshold)

[white elbow]

might be a dumb question, but how do "picked up" items exist in the game world? like when you pick up something and it disappears and shows an icon in your inventory

[gentle urchin]

Varies greatly

[spark robin]

How do you rotate content browser images again? I can remember there being some like keyboard combination, I cant just recall what keys it invovled :c

[gentle urchin]

some games keep them around as their actual "actors", some make them into "Objects", and others keep them strictly as "data"

[white elbow]

what's the difference between objects and actors?

[gentle urchin]

Objects dont exist in the world

[willow pike]

I started with this guys tutorial: https://youtu.be/2fdpqBBhWmw

[humble sleet]

you can have the in-game item as a thing with a mesh and a link to some data

or you can have it as the full actor with all the logic

[willow pike]

Thanks for the replies, I will play around with the two. I have it set up with line trace right now and everything works as expected but I am in a third person perspective and it seems I have to get really close and find the "sweet spot" so to speak.

[humble sleet]

in the first case you'd keep the logic stored within the 'inventory', insofar that you don't need to use the logic if the player isn't holding the item

I think that's the case, at least

[gentle urchin]

the accuracy part ^^ I've also seen capsules rotated outwards, which would solve the treshold part aswell

[long schooner]

Hey guys, do you know any good flying tutorials??

[humble sleet]

https://www.youtube.com/watch?v=nb74_jkr8u0

I kid

[gentle urchin]

Its good

[long schooner]

Thanks xD

[gentle urchin]

serious reply

😛

[humble sleet]

I posted the wrong video

https://www.youtube.com/watch?v=ZBEipeiKxh0

[long schooner]

how about in unreal?

Lmao

[gentle urchin]

just do custom movement,

add some Z to the char

and watch it fly

[humble sleet]

idk if you've seen Reid's Channel

[gentle urchin]

What sort of flying are you after anyways

[humble sleet]

I think he has tutorials for a jet and heli

[gentle urchin]

superman ? dragons?

Planes?

[willow pike]

Isnt there an example flying project?

[gentle urchin]

there is

[humble sleet]

I'd love to remake the flight from Freefall Tournament

[gentle urchin]

I (ignorantly) assumed it didnt suffice, my mistake

[willow pike]

lol no worries

@spark robin well well well, look who it is!

[spark robin]

https://tenor.com/view/zootopia-nick-wilde-blink-wink-gif-14259357

[humble sleet]

thanks for the reminder lmao, I did know this was a thing but completely forgot about it

[gentle urchin]

One of the templates , as Harry pointed out

[long schooner]

Thanks 😄

[gentle urchin]

there's quite a few classes to keep in mind , so easy to forget any one of them 😛

[humble sleet]

I think I should be fairly safe to make the main menu be its own self-contained thing

[trim matrix]

How can you

[gentle urchin]

I gotta should stop procrastinating now

[humble sleet]

so I can use (what feels like) ugly hack code

[trim matrix]

Like

Guys

[gentle urchin]

Do it!

[trim matrix]

I saw a reddit post in which the player controller was flying

[tawdry surge]

My main menu is usually it's own level

[trim matrix]

Like supperman

How can I do this

[humble sleet]

that's what I've got

but

it just feels wrong

[gentle urchin]

same. With its own GameMode, and PlayerController

thats my basic setup for it anyways

[humble sleet]

hwuwh

why it's own controller?

[gentle urchin]

Feels right i suppose

[humble sleet]

ahA

[gentle urchin]

no good reason

[humble sleet]

so I'm not alone

[tawdry surge]

It's just cleaner, and controller is best since the pawn is usually not used

[gentle urchin]

I dont make a HUD for the main menu tho 😛

even if I should, I dont

[tawdry surge]

Can set show cursor, click events, lock view etc..

[gentle urchin]

yepp

very handy

[humble sleet]

do you mean HUD as in the specific HUD class, separate from UMG?

[gentle urchin]

Yeah

as the container for the widgets

[dim tapir]

It seems It's not even recognizing my "AnimNotify". How can one fuck that up?

[humble sleet]

I thought the HUD class was just an old feature from before UMG

[gentle urchin]

Anim notify is unstable 😄 ?

[gentle urchin]

Perhaps it is. But it has some things you cant (to my knowledge) do elsewhere aswell

[humble sleet]

go on

[humble sleet]

ok so not anything I'm really going to need

[gentle urchin]

Unlikely 😛

[humble sleet]

thanks

[gentle urchin]

As I said, I never create it for my main menu

[humble sleet]

I never create it

[gentle urchin]

period lol

It's nice to keep all widget stuffed in a single class imo

instead of bits and pieces all over the place

[humble sleet]

that's why I was trying to use that horrible delegate setup

[gentle urchin]

delegates are great

Functions should be embraced

[humble sleet]

even this?

[gentle urchin]

Almost

I'm not satisfied with my setups yet

but i prefer to let the owner of the widget do the registration

owner being whichever class made the widget

[humble sleet]

I was trying to put all the actual logic in the menu pawn, and just have the menu buttons announce that they had been pressed

[gentle urchin]

Right

but you'd reverse it

[humble sleet]

but then if it's just a navigation button like options, then it's the widget itself that needs to be listening

[gentle urchin]

Pawn creates widget

registers the dispatchers

[humble sleet]

ah

[gentle urchin]

thats how I would do it

[humble sleet]

you see, I had the menu level blueprint creating the widgets

[gentle urchin]

I avoid the level bp like the plague

[humble sleet]

ok

that's the sort of thing I want to hear

[trim matrix]

If I were to make my own player controller how could o got about it

[gentle urchin]

subclass the playercontroller

[trim matrix]

Like what if the player gets stuck in a wall

If the player gets stuck in a wall

Can just detect the collision and get the normal to check if wall and if so don’t execute addforce

But the friction

[bold shard]

I'm trying position a widget on screen, based on a percentage, but it doesn't work. If I set it to 1/1 the widget shows up halfway down, and most of the way to the right. I'm not sure what I'm missing.

[humble sleet]

where is the widget anchor set to?

idk if that might affect it

[gentle urchin]

an example of it, reversed. Widget just listens for events

[bold shard]

Bottom middle, I can try setting it to somewhere else

[trim matrix]

If I were to add a force to an object and it hit a wall will it slide down or just get stuck

[humble sleet]

I was referring to a button widget

that has a click event

[gentle urchin]

I'm aware. Hence the reverse

[trim matrix]

In unity if a rigidbody gets stuck in a wall so you have to set friction to 0 and use drag to make fake friction

[humble sleet]

how does that help for a menu button though?

the event comes from the innate functionality of the button

[gentle urchin]

Its just a dispatcher in the button widget ,

so i'd just pass it forward

[bold shard]

Tried some of the anchor options (top right, top left, bottom right, bottom left, middle) and none fixed my issue. The widget was still misplaced, just in different spots

[trim matrix]

I need to test these

[humble sleet]

so I make an event in the menu pawn, and make it fire when the event in the button widget goes?

[humble sleet]

ohhh yeah I get you now

I was still working on the basis that my widgets are being made in the level bp

[gentle urchin]

Well, you could still pass it forward..

just ... more work

[humble sleet]

keyword being 'was'

I am taking your advice

[humble sleet]

also I still don't fully grok delegates/dispatchers so I don't know what 'pass it forward' means

ok that's basically what I had originally

[dry condor]

is the alignment changed ?

[humble sleet]

which I didn't like because casting

casting bad

[gentle urchin]

casting is fine, but I avoid it if it makes sense

Like.. Does it make sense to store a widget in the levelblueprint?

Is it unique to that level?

[humble sleet]

no

[gentle urchin]

tied to that level ?

[humble sleet]

well

[gentle urchin]

So then your cast becomes extra work, for no good reason

[humble sleet]

the main menu buttons are going to be unique to the main menu lvel

[bold shard]

My alignment is set to 0.5, 1.0. Changing the anchor doesn't change it. Should I try modifying this?

[humble sleet]

so kinda

[gentle urchin]

Lol, true, but still

[humble sleet]

yeah

[gentle urchin]

If you decided to swap main menu level

[humble sleet]

that's why I was stuck

[gentle urchin]

you'd need to do it again

[humble sleet]

because the bad option still made too much sense

[dry condor]

that may be the reason why its not where you want it to be, change both to 0 and see if its better

[humble sleet]

honestly I wish there was just a massive list of best practices for every possible thing

[gentle urchin]

And I'm still not getting my work done.. sigh joke, its on me

[gentle urchin]

I agree

that would be great

[humble sleet]

anyway, thanks for pointing me in the right direction

[gentle urchin]

General OOP practices apply I guess

[humble sleet]

not a coder

well

I know MATLAB

[gentle urchin]

😄 It's something 😛

[bold shard]

Did not work unfortunately, didn't really make a noticeable difference

[humble sleet]

honestly if Unreal had MATLAB's matrix op stuff it would be amazing

[dry condor]

well it at least should appear where you set it to be

[gentle urchin]

I wonder if there's any way to set variables to private as default ..

[humble sleet]

is it a good idea to save a ref to the player controller or just use a get each time?

[gentle urchin]

Depends ..

[humble sleet]

up until now I've been caching everything

[gentle urchin]

Do you use it a lot ?

[humble sleet]

probably not that much

[gentle urchin]

likely insignificant difference then

[loud parrot]

good

[gentle urchin]

I prefer saving them

while i dont mind casting when it makes sense, its that extra step

over and over

[humble sleet]

oh if I'm casting then ofc

[bold shard]

Figured out my issue. Had to multiply my X and Y by the inverse of the viewport scale.

[fiery swallow]

If you have code you use a lot and it's generally small you can always put it in a macro. That's what it's for

[humble sleet]

but then I just realised I did mean to cast in this case

[loud parrot]

I also save it as a reference, it will be cheaper than calling it every time

[humble sleet]

but hadn't actually so it seemed pointless

[gentle urchin]

I wouldnt put a cast in a macro instead of caching it , but thats me 😛

[humble sleet]

one other thing, would it make sense to set up cached stuff like that in the construction script?

or is that not what it's for?

[gentle urchin]

construction is risky

[trim matrix]

How can I Make a derivative of the player controller

[gentle urchin]

things may yet exist

[humble sleet]

idk what the constructerino is for

[fiery swallow]

https://docs.unrealengine.com/4.26/Images/ProgrammingAndScripting/Blueprints/UserGuide/Macros/score_comparison_example_macro.webp

This is an example of good macro use directly from the docs

small code intended to be used often

[loud parrot]

it's ridiculous

[gentle urchin]

Seems reasonable

[humble sleet]

macro library :kekw:

[gentle urchin]

I should probably use it more

[fiery swallow]

so if you have like 4 or 5 nodes you are going to need to use often, but you don't want to save it as a variable. Macro is your man

[gentle urchin]

But its like.. It's never so often that it feels worthy to use a macro

[fiery swallow]

I do it alot for getting the anim blueprints

[loud parrot]

Functions a cheaper than macros

[fiery swallow]

just feels cleaner to me

[fiery swallow]

depends

[gentle urchin]

I use construction script for things like setting up an Actor procedurally mostly

[gentle urchin]

As it always does

[loud parrot]

Macros are needed if additional pins are needed

[fiery swallow]

I don't know about that chief

[gentle urchin]

Functions cant be latent

macros can

[fiery swallow]

they both win in clear cases fam

[humble sleet]

@gentle urchin about the set/get caching thing, I just noticed this

[gentle urchin]

Confirmed my short analysis, perfecto!

[loud parrot]

yes, pins, latency, enumeration of arrays.

[gentle urchin]

So its just a hidden get inside the set 😛

[loud parrot]

In c++ it is possible to create additional output pins for a function

[gentle urchin]

Exec pins? (wasn't specified, I know)

[loud parrot]

yes

[fiery swallow]

There's a reason why ue has some native nodes in functions, and some in macro :/

Some things you just dont want in a function

Specifically because functions are expected to return something immediately

[gentle urchin]

Input

[loud parrot]

oh sorry i messed up

[gentle urchin]

I've seen this in some plugins

not often used to my knowledge

[trim matrix]

The

[loud parrot]

You can create any number of pins using k2 nodes, but it's difficult

[naive stag]

How can I get 'Reverse For Each Loop With Break' ?

[gentle urchin]

So I've heard

[gentle urchin]

reverse engineer it

[naive stag]

Ill end up with 2 for each loops then

[gentle urchin]

how so ?

Btw

are you using it inside a function ?

[naive stag]

no

[gentle urchin]

If so, there's a pro tip laying around

ok

well, if we disect the foreachloopwithbreak

[loud parrot]

when compiling, the code from the macro is copied to the place where you call it. and if you use a macro a lot, it's better to remake it into a function

[gentle urchin]

all its doing is setting a bool to true on break

[gentle urchin]

compare it to the reverse for each

all we need to do is figure out where and how to add the break

[naive stag]

just gate it

[brittle osprey]

whats the difference between macros and event dispatchers

[tight schooner]

Everything...

[loud parrot]

its a two different things

[brittle osprey]

what do they do thats different?

[tight schooner]

... Everything...

I would start by reading up on both

Macros are just a node graph helper so you don't have to copy paste nodes as much

[loud parrot]

I would advise you to read the documentation, or look at the examples

[humble sleet]

so in here

where is this function?

[naive stag]

ye that will do it

[gentle urchin]

In the MainMenu widget (containing the button)

[humble sleet]

and where is the event dispatcher made?

because I don't have an option to plug the button reference into the bind

[gentle urchin]

In the Pawn (since thats who wanted to listen to it in your scenario)

[humble sleet]

ahhh

that would do it

[brittle osprey]

im more artist than programmer so sorry i dont understand........

[gentle urchin]

A macro is basically a pastebin for code

While a Dispatcher is a callable event that is executed on every listening actor

[fiery swallow]

I already know about UE pasting the code to the board but I'm pretty sure if they thought it was a good idea to do everything in functions that can be done in a function. They would not have hundreds of these macro nodes

[humble sleet]

so a dispatcher is a dude ringing a bell, and anyone listening does their stuff upon hearing it

[gentle urchin]

not that many

[gusty shuttle]

Might have an easy question. I'm trying to do a map mouse zoom in, however it only does it once in zoomed in or out currently. Why wont it keep getting tranform scale and adding every time I mouse scroll?

[loud parrot]

Yes, without macros it will be difficult

But I don't understand why they wrote some blueprint macros

If it was possible to do it in c++

[gentle urchin]

dispatcher is closer to the radio 😄 Anyone tuned in on the frequency has the opportunity to react to it

[fiery swallow]

Pretty sure there's more then that in the form of plugins

[gentle urchin]

surely

this is the standard library

[fiery swallow]

True

[brittle osprey]

and i take it a dispatcher is "this event happens" and everything who is listening (in this case "calling" it) does something related to that event?

[gentle urchin]

the listeners are "bound" to it, while the caller is the one sending out the broadcast

Event dispatchers in a nutshell are amazing

[maiden wadi]

@brittle osprey A macro is a predefined set of code, very similar to a function with minor differences. If you're not a programmer, you probably won't care about the difference and should try to use functions more.

An event dispatcher is like a pager service. You page the dispatcher, and it sends a message to everything that has subscribed to it. You use it to notify multiple objects that something has happened. For example, if a character has a health variable and you have a dispatcher. You would set the new health value, and then call the dispatcher. Then everything registered to it knows that health has changed and they can update. Materials can be changed to be more bloody, healthbar can change numbers and progress bars, hud can spawn a floating damage widget, etc. All from one single actor calling it's dispatcher.

[gentle urchin]

You've perfected the analogy

i like it

[brittle osprey]

THAT makes sense to me thank you SO MUCH

[tight schooner]

I remember an epic training video that was like, an event dispatcher is like a Twitter feed...

Actors can follow the feed

Lol

[gentle urchin]

xd

[humble sleet]

potentially silly question, what would be equivalent to the opposite?

[maiden wadi]

I suppose a Twitter feed is a more modern terminology. 😄

[humble sleet]

like a secretary who everyone calls

[maiden wadi]

Functions in GameState or similar.

[gentle urchin]

An interface is the closest you'd get

well,

kinda, but not really

[tight schooner]

The diff is like who has the object reference for the other thing. The object doing the dispatch doesn't need object references to the listeners

[gentle urchin]

a function is equivalently close i guess

[dry condor]

caution, dumb question: wouldnt a interface be kind of like an event dispatcher ?

[gentle urchin]

It would, but on a one to one basis

[maiden wadi]

Interfaces are nothing like dispatchers. In a perfect code base, interfaces are actually useless.

[gentle urchin]

I see I should stop talking xD

[tight schooner]

But a more direct form of communication would be like (for example's sake) get all actors of class and then calling functions / sending interface messages etc

So it depends how you want to set up those relationships

[maiden wadi]

Interfaces are a patch to the fact that we can't insert functionality to Actors or UObject, so we have to have a way to call functions on objects of differing hierarchies. Interfaces patch that issue, but it's still just that, it's a patch.

[fiery swallow]

I mean you're right about the one to one basis

[craggy hatch]

can someone help me please im stuck🥲

[tight schooner]

Click on that "set world location" link in the message; that's the node causing the error

[dry condor]

you are trying to access something that does not exist

[tight schooner]

Accessed None means you're giving it empty data

[gentle urchin]

Almost looks like its done on tick aswell, given the amount

[craggy hatch]

but it exist

[tight schooner]

Idk are you destroying the actor before that timeline finishes?

[fiery swallow]

I mean interfaces can have its uses outside of that right? I feel like it gets pooped on more then is necessary. There are a lot of times I feel like BPI's save me a lot of trouble, and are just more neat from a blueprint perspective

[craggy hatch]

no

[loud parrot]

check actors for validity
