blueprint

[latent venture]

I am also using the same static mesh for multiple doors

[dark drum]

You'll need to provide more information. Regardless of which method you use you still need a reference.

[agile moss]

Basicaly a sender and a receiver

Simple
Idk what refference

[dark drum]

Get the ism component and get instance count.

[dark drum]

You're still being cryptic. What are you actually trying to achieve? What's your end goal.

[agile moss]

Ok ok
So a BP that holds the info to all levels
I need the specific location that is stored in the bp to be send to the BP_BORDER

[latent venture]

ah ok, thank you very much, but like, does it help refere to only one of them?

[faint pasture]

how does caller know about reciever?

[agile moss]

You mean the reference?
Like "target"?
That is what I want to find out
I give up

[restive token]

I dont know what the correct word for this is but:

How do I make an axis value "stepped". For the joystick, instead of getting a gradient from -1 to 1, how can I make it so it only gives me
-1
-0.5
0
0.5
1

so that the joystick movement is not gradual, but instead it's in steps

[faint pasture]

it's up to you

what is the caller and what is the reciever? What is the relationship between them

[faint pasture]

do math on the raw value to produce the stepped value

in your case it'd be multiply, round, divide

raw -> multiply by 2 -> round to integer -> divide by two

[agile moss]

Oke
Up to me...
This is third level rocket science

[faint pasture]

If you were making a damage interface, the bullet might call DamageInterface.TakeDamage on the thing it hits.

Explain what your things are

all we know is you have two things and you want one to talk to the other

[agile moss]

Ik what u mean
In an event begin overlap u have other actor as refference
Rn I dont have one of those things so I just have to find out myself

I will just watch more tutorials, probably find out over time

[faint pasture]

Show what the 2 actors are

[agile moss]

Here

[velvet pendant]

hey guys

i have a little problem

that i can't solve

dunno where's wrong

what's wrong w the first char

same code in seccond

[faint pasture]

Feedback

you rotate to look at the point

therefore rotating your camera

therefore moving where the point is the mouse is over

like a dog chasing its tail

You want a top down aim system like this right?
https://www.youtube.com/watch?v=t1-vhWNlTMI

[velvet pendant]

Not really, i just want the player to look the same direction as my mouse

[faint pasture]

but the act of looking moves what your mouse is over

[velvet pendant]

i want to make a Tower Defense game, where you can build the towers, by pressing q

so he's facing the direction of the mouse

[faint pasture]

and what's the camera doing?

[velvet pendant]

wdym what's the camera doing?

[faint pasture]

do you want the camera to be rotating or not?

[velvet pendant]

yes.

wait, no, just the pawn

i readed wrong

sorry

just the pawn to rotate where the mouse land

as this pawn

the same as this pawn i want to be, but can't get it, wtf is wrong with the other one

[faint pasture]

The difference between these 2 characters is that the camera rotates along with the pawn in the 1st one and doesn't in the 2nd

[velvet pendant]

so, i gotta lock the camera

[faint pasture]

have the camera for the 1st one use control rotation so it ignores the rotation of the pawn

yes or do something else

What you have right now is like a cat chasing a laser pointer. It can catch it unless the pointer is attached to the cat, then it'll chase it forever

[velvet pendant]

Yea, i get that, but for now, it's a deal for me, since i just need to do the GRID Map, and placing the Gems on the ground, gonna make it smoother later a bit

just now, i need to create a basic template so i can think all the systems, then polish them all

that's how i see things in my workspace

idk

[faint pasture]

What does any of that have to do with the camera?

[velvet pendant]

nothing, i'm just saying that the way this way of rotation is good

for me rn

[maiden wadi]

Anyone in here decent with RTs? Trying to find the best way to manage blending an RT from one state to another.

[mental trellis]

Render both states and lerp it in a material?

[dry pecan]

would a boss be considered an actor or character?

[hazy jewel]

Anyone know how I would be able to have my damage system adjust the damage multiplier based on physics body hit location? I was thinking I could tag the physics bodies based on value but my googling has not yielded results. Would doing something like name contains part be a possibility? That's my if nothing works option because the enemy has a lot of legs and bones but wanting to be able to specify. Pic is just the sphere trace and the damage system being called

[dry pecan]

so question, I'm currently trying to momic shooting like this here: https://youtu.be/cWiT-VuPgMk?si=Z5ea9Vey1_aSuql1 . My approach is to essentially use the enhanced input system which I simply set for holding down the left mouse button, am I doing it right so far to best mimic it? I made a projectile object that will shoot from my player, any tips on how to spawn said projectile? I'm using hit result to create the path the bullets will follow while mouse is being held down

[undone bluff]

read up on the basics 😔

get your foundations

it'll save you so much time

[velvet pendant]

how i can move my camera with wasd, not my pawn?

[undone bluff]

the white execution line is what matters, the action value is simply the state of the input which is not useful here

[brave isle]

anyone here have any cue about what's happening with chaoes vehicles in UE 5.3.1 ? like the bones doesn't get the animation proprelly ( was using 5.1 and less and never had that trouble so far ) ( vehicle falls inside the floor like the wheel arent fonctionning ( it stay stuck at the box collision of the mesh body ) ) really starting to think 5.2 and 5.3 are just downgrades at that point might go back to 5.1 xD ( having kinda the same trouble with 5.2 but in 5.2 the vehcile just keep falling inside meshes like nothing is there under them)

(Edit: Look like a export error from blender il investigate this further)

[dry pecan]

but if I use input action, its only for once when clicked and not held down

[undone bluff]

Triggered is called every frame

[dry pecan]

ah yes thats why I'm using the enhanced input system

[undone bluff]

though it's better to set a timer on Started and clear it on Completed

[dry pecan]

I'm assuming thats for the bullets so they dissapear after being shot, that way the editor doesnt overload with all the stray bullets

[undone bluff]

no that's to actually shoot

no point in trying to shoot every frame

and have cooldown logic on top

[dry pecan]

do you mean like when I hold down the mouse button, a timer starts, and as long as that runs the player will keep shooting, but when the player lets go said timer stops and so does the shooting

[undone bluff]

you can hook up a delay and then shoot on triggered and it'll work, it's just jank and the gun will always shoot one extra round

so you can add a gate and then it's already a more complex and less readable setup than a timer

[undone bluff]

yes

[dry pecan]

Oh I can just use a left mouse button node if that's the case

Only thing left then is just spawning bullets since I know I can sinpky just use a transform, because I know how to make the bullets fly and how to trigger what they need to do, I just don't know on how to make them appear one after the other

[undone bluff]

what do you mean by that

[dry pecan]

like I need to establish a point on the character where the bullet will first spawn, they need an origin point, and they'll be spawning one after the other since the player has infinite ammo like in all arcade games

[undone bluff]

so place a scene component at the muzzle of the gun and use that location

[glossy inlet]

Or use an Arrow Component and get the Transform of that

[undone bluff]

we only need the location though

[glossy inlet]

Transform is location or just get world location of that arrow, or forward vector

[mental trellis]

And it's rotation and scale

[undone bluff]

i mean whatever but what is the arrow for we just need a place to spawn the bullet and I said scene component because that's the most low level component with a transform

either way, there'll also likely be the matter of actually creating an aimoffset to even point the gun to the place the player is aiming

[dry pecan]

this is what I've done so far, looks like it does hit stuff as I've seen print string work

[glossy inlet]

Could always add a socket to your mesh and name it, call it for coordinates, I have used Arrow before to show direction of fire attached to mesh object and call trace's from it.

then spawn your pojectile from that vector

[undone bluff]

yea, socket is needed when you want to specify a muzzle location per gun

really, in general the better approach, but trying to hold off a lil on sending this person on side quests

they haven't even made a timer yet

[dry pecan]

I just added it, Set Timer by Event

[undone bluff]

yep, that's fine

[dry pecan]

I'm assuming then that left mouse is actually making an event happen?

[glossy inlet]

yes

[undone bluff]

it sets a timer to call a function/event delegate after a delay

so for shooting you'd use the looping set to true

[undone bluff]

you want the timer to call the event

your input should set the timer

[glossy inlet]

Anyone know how to check a vector with a bool? Ive got a bugged Distance / Valid check system. It will fire all day long when its in range, goes out of range the bool breaks and i cannot fire again. I disabled a Isvalid check and was able to get it to reset, but its now throwing errors on the destory logic.

though about vector select but im not sure

select is on "end" trace

[dry pecan]

wait I thought the event started the timer?

[undone bluff]

no, the other way around

started > set timer
completed > clear timer

or pressed and released not sure why you dropped the enhanced input system

[dry pecan]

because you said it was it wasnt a good idea to do it per frame

[undone bluff]

no need to drop the entire input system because you don't need one feature

[dry pecan]

ok there we go

[undone bluff]

you are missing out on mapping contexts and keybinding

[undone bluff]

you don't need to use the system for prototyping ofc but you already had the input set up so I was confused why you dropped it

the return value is the handle of the timer

promote that to a variable

that's your reference to the timer

then you use it to clear the timer when on completed

that's all there is to it

[dry pecan]

I'm assuming I do that on canceled?

[undone bluff]

completed

cancelled is only relevant if you have a chorded action setup

it's called when that failed

[dry pecan]

and there we have it!

and I setsted iy out with printstring and it works!

[main lake]

@dark drum Any news ? #blueprint message 😄

[dry pecan]

you meantioned scene compont, do you mean an actor componet?

[undone bluff]

actor components do not have a transform

they are just logic you attach to an actor

[undone bluff]

you don't need the second set on completed

just use a get node

to make it a lil cleaner

[dry pecan]

like this?

[dry pecan]

apologies just want to make sure, since I dont see any options to end loop for the timer refrence in details

[dry pecan]

So could I ask what I should do now with the scene component , I get the transform for the projectiles which is very easy, I just need to now to do the spawning now

Also before you ask, yes I already created one

[main lake]

@undone bluff Any help my almost 3 week issue please ? 😄 #blueprint message

[undone bluff]

oh you used set timer again

no I meant you don't have to set the timer handle again

what you want is clear timer (by handle)

[dry pecan]

Oh found it, it's all good now

[undone bluff]

yep

[undone bluff]

probably not my networking isn't great

[dry pecan]

all thats left is bullet spawning, the only thing I dont get how, I can get them to follow a transform, I just need to figure out how to make them appear

[main lake]

https://tenor.com/view/kid-baby-child-girl-tired-gif-16635701

[undone bluff]

spawn actor by class

it's called something like that

[dry pecan]

but I cant seem to use the scene componet as an origin

[undone bluff]

scene component > get world location

[dry pecan]

ok so for some reason the bullets appear at the end destination

[undone bluff]

yea you are setting the transform of the bullets to the hit location

[dry pecan]

how can I translate then? looks like I did the wrong node

[undone bluff]

you are spawning the projectile using some transform that's offscreen and then setting the transform the the hit location of the trace

https://forums.unrealengine.com/t/how-do-you-get-projectiles-to-shoot-at-cursor-location/677810

look at the second post here

it explains how to set up the projectiles

[dry pecan]

wait but then what about this?

[undone bluff]

???

[dry pecan]

oh I dont have to do that part, looks like what I need to do is within the projectile actor, is Projectilemovememt and scene componet?

[undone bluff]

yes

you already have this first part

[dry pecan]

can I ask what componet type this is?

[undone bluff]

it is what it says

are you unable to find it?

[dry pecan]

I'm sorry if I'm blind, Ifrom how its set up, its as if its already there

[dry pecan]

Ah my apologies, I though it was a custom component

[dry pecan]

where does the set comefrom?

[undone bluff]

look at the target

the parameter velocity is a property of the projectile movement component

[dry pecan]

i figured it out, all thats left is spawn actor, all I keep getting is spawn actor by class

[undone bluff]

that's it

[dry pecan]

I'm an idiot, I forgot to split

[dry pecan]

odd, cant find velocity

[undone bluff]

you mean NewVelocity?

you are supposed to create that

[dry pecan]

I did

[undone bluff]

did you tick the boxes?

save and compile?

if both yes right click the node and refresh maybe

[dry pecan]

they arent appearing, maybe my rate is too slow and they bump into each other?

[maiden wadi]

I'm inclined to say use the hit bone or physmat. But it really depends on how you want to do things.

But in general for bones, you simply set up maps for each skeleton you have. You can even walk up the skeleton hierarchy to find the closest parent in the map in some cases. But a simple map of skeleton to a struct that houses another map of bone to float would make for incredibly fast lookup. You just need to pass the hit component, and bone through to the damage system to let it look it up.

For the phys mat, it's a little easier on the coding side, as you literally just make a map of physmat to float and simply look it up. If nothing use 1.0 multiplier. Then you just apply that to your assets where you want multipliers.

Both require a minor bit of coding, and a decent amount of asset setup.

[undone bluff]

your execution line is disconnected

[dry pecan]

ok new problem, shooting only happens when the get hit result hits something

[hazy jewel]

This is great info! I had considered doing a struct so glad to know I was kinda on the right path. I'm going to do some reading on the physmats for now!

[undone bluff]

if the trace doesn't hit, use the trace end location instead

you can set that up with a select vector node

[dry pecan]

still happens

[dry pecan]

any other ideas why? or am I still wrong?

[undone bluff]

that's odd

show the rest of the nodes maybe

ah

yea

you got the branch at the beginning

remove that

[lunar sleet]

And how do you get the velocity if there’s no hits ?

[undone bluff]

ah, does it return a completely empty hit struct?

[lunar sleet]

Like what happens if new velocity is w/e comes out of that get unit direction (vector)

[undone bluff]

I'd assume it'd at least give you the trace end

[lunar sleet]

Curious what that will end up being, from world location to… 0,0,0?

[dry pecan]

it does this now

[undone bluff]

yep

so it is empty

[lunar sleet]

Oh I guess it’s trace end, you’re right

[undone bluff]

linetrace gives you the trace end separately

but we don't have that luxury here

[dry pecan]

so I should do trace end?

[undone bluff]

probably no way around finding it out yourself

give me a sec

[dry pecan]

yeah still doing that same

[undone bluff]

yea there is no hit struct, not even the information about the trace itself, if there is no hit

I did this some time ago but I cannot remember how

[dry pecan]

how can I fill in that info?

[undone bluff]

by doing what the get hit result under cursor node does yourself

[dry pecan]

waityou mean delete get hit result?

[undone bluff]

no

deproject screen position to world

[slate hound]

this?

[undone bluff]

uuuh perfect

thank you

[dry pecan]

ok so delete this and just plug in that to here and there

[undone bluff]

nono that's fine

[slate hound]

if no hit result use this basically

[undone bluff]

exactly

[dry pecan]

where should I chug that in?

[undone bluff]

select vector first of all

one input will be impact point

[undone bluff]

the other will be this

but you need to multiply the direction by a big number and then add it to the location

[slate hound]

or the wildcard one

[undone bluff]

I guess the wildcard is the more up to date workflow

for Pick A you just get the hit result return boolean

so when there's no hit it uses the B vector

[undone bluff]

I like that the pins are actually called False and True when you use a bool, I don't know what they were thinking when naming the pins A and B for the old type specific ones

[dry pecan]

IT WORKS!!!!!!

[slate hound]

ya it makes sense 0 (false) first, 1 (true) second

[dry pecan]

thank you all so much:D

[slate hound]

where's the video?

[dry pecan]

all thats left for me to figure out is why are the bullets not colliding with the floating robot, my gut tells me its the robots fault but I just dont know why

[dry pecan]

is it probaly a problem with the collider of the robot? or the material?

[slate hound]

nice looks good

def not the material

[dry pecan]

probs the collider of the robot?

[faint bramble]

hello

can anyone tell me how we can make a levels come randomly

[undone bluff]

level names as strings in an array, randomly pick one and load level by name

[valid solstice]

Does anyone know how I could make the charge attack go through the enemy?

[undone bluff]

https://dev.epicgames.com/documentation/en-us/unreal-engine/BlueprintAPI/Collision/SetCollisionObjectType?application_version=5.3

[tacit vale]

I cant seem to fix an issue with my projectile and cross hair. My projectile is not hitting the center of my crosshair and I cant figure out why.

[wild sage]

How can i reproduce the function of this node on unreal engine 4.x ? This node only exists in 5.x versions

also this node

[lunar sleet]

You write your own in C++ or you upgrade

[frosty heron]

Strings are error prone tho, I would use array and soft ref. Then open level using soft ref

[undone bluff]

Good call

@faint bramble

[faint bramble]

yes brother what happend

[frosty heron]

@undone bluff but for what ever reason, levels are not exposed to blueprint by default

So need some cpp to declare the array

[undone bluff]

Oh that's what I thought

[undone bluff]

Nevermind, sorry. 😔

[faint bramble]

no sorry u tried to help

[frosty heron]

If u don't have many level, u can just do random int in range and a switch

Then just open different level respectively

I really don't want to type a map name if possible

A typo or if you change the map name, your game breaks

[frail onyx]

anyone know how i can make the player look through a camera that is on an actor that i have rotating around a point?

whenever i press play it makes me go into the default free fly mode

im trying to make something similar to the rotating movement as shown in the beginning of this video https://www.youtube.com/watch?v=6U_OZkFtyxY

[frosty heron]

Looks like a normal camera with spring arm

And just change the rotation

[frail onyx]

would it just be done using a normal actor with a spring arm and camera attached?

[frosty heron]

Sure thing

[frail onyx]

i cant seem to figure out how to get it to actually use the camera once play is pressed though

[frosty heron]

If it's Ur character then just posses the character which also own the camera

If u want to have multiple camera, make sure u activate the one u want to use

[maiden wadi]

Can also just SetViewTargetWithBlend with a zero blend, from the player controller if you don't want possession.

[frail onyx]

i dont have a character at all though

[frosty heron]

If u are not gonna control the rotation with your mouse then you can use set view target with blend

[maiden wadi]

If there are zero camera controls at all, and it spins at a fixed distance, there's also level sequences with a spawned camera on a track that repeats.

[frail onyx]

just want to have a view be out of a camera that is automatically rotating

[frosty heron]

Just make an actor bp with a scene comp , a cam and spring arm

Then write the logic to rotate the cam

Which is just a Finterp on one of the axis

Or maybe add rotation works

Actually don't do add rotation you want to count delta time

[maiden wadi]

You can still add rotation multiplied by delta time.

[frosty heron]

True

[maiden wadi]

Also CameraManager which you can override it's camera update event and do the logic manually to determine location and rotation each frame based on which actor you want to look at.

TLDR there's a ton of ways to make a simple rotating camera. 😄

[frail onyx]

im still confused on how to actually get the player to see out of it when i press play

[frosty heron]

Out of it?

[frail onyx]

out of the camera on the actor

[frosty heron]

U r given some keywords tho?

[frail onyx]

do i need to place down the actor into the world? or the player start

[frosty heron]

Where ever you like

That's for u to decide

[frail onyx]

when i press play though it lets me move around as if i was in the viewport

and doesn't lock me to the camera on the actor

[frosty heron]

Do you posses the actor that hold the camera?

Anyway go for easier mode. Use set view target with blend

Plug the actor that have the camera and the controller

[maiden wadi]

For a more thorough explanation the camera manager controls the view of the player.

It normally does this via a SetViewTarget on the controller's possessed pawn.

If you don't want to possess a pawn, you can override this behavior with a SetViewTargetWithBlend call from the PlayerController.

The view target, regardless of where it is set at will find the first activated camera component on the actor(note this is actor, not pawn or character, as any actor can be a view target), and it will use that camera's settings and transform for the display.

You can also override the update event in a camera manager subclass that you specify on your PlayerController class, which overrides any sort of view target logic.

[faint bramble]

we have 100 level brother we are a game dev team we have very skilled people but we dont have any one for animation and rigging

[frosty heron]

How'd that have anything to do with animation and rigginf

[faint bramble]

no no i was telling we need somone

[frosty heron]

And if they r skilled, surely they can declare an array of level soft ref in cpp

What u r doing is super basic btw, and I'm saying this as someone who doesn't know much

[frail onyx]

did i do this correctly?

[faint bramble]

they are working on it but i do not know about bp so i asked

[frail onyx]

im in play mode right now and im looking out of the camera but for some reason im still able to move with the default movement when you have a blank project and press play and there is a sphere moving around when im moving wasd and pressing e and q to go up and down

[frosty heron]

You most likely in spectator mode. Don't simulate game, press the play in editor

[frail onyx]

i am pressing play

[frosty heron]

If u don't have any actor, it is defaulted to spectator pawn afaik

Make a character and use that in your game mode instead

[frail onyx]

like have my blueprint actor with a camera inside placed in the world and then make a blueprint that is a player controller?

[frosty heron]

if you don't want to see the ball (Default Pawn), make your own pawn and set that as the pawn in the game mode

[bitter star]

Is there a way to change the aspect ration of the Vcam to make it vertical? It's not letting me change the values even in custom so I’m thinking maybe through BP?

[frosty heron]

@faint bramble if you have 100s of level like you said, this is probably the sanest way to do it

UPROPERTY(EditAnywhere, BlueprintReadWrite)
TArray<TSoftObjectPtr<UWorld>> LevelsToLoad;

For the array. World is not exposed to blueprint by default

[faint bramble]

okay

[gentle urchin]

(There is a random node for arrays)

[faint bramble]

thanks bro

[gentle urchin]

If you dont want to expose tyat from c++ i think you can do level names with . in them?

If so you can make gameplaytags for each , altho quite many i guess

[maiden wadi]

PrimaryAssetIDs

@faint bramble
Should use PrimaryAssetIDs. Make an array of them. They'll show anything you've specified in your asset manager.

Go to project settings and then asset manager and make an entry like this or edit one that's already there if it has the maps already.

This also makes sure that these assets get cooked, so you don't have to do that annoying hard coding level name crap in the cooking settings.

Side benefit, no C++ required since UWorld is already set up for this.

[faint bramble]

okay thanks brother

[gentle urchin]

I really should start using those 😁

_ some day_

[worldly wagon]

anyone familiar with the horror engine available in the marketplace? i wish to edit the paper information in the blue print. i wish to add in paragraphs to the text description

in the inspection settings i activate the multiline so i can use shift+enter to drop a paragraph

but the paragraphing is not correct in game. is there anything i'm missing? just learning unreal not too long ago

appreciate some help on this

[white thicket]

The parameter is not changing anyone know why?

[faint pasture]

you need to show way more than this

what is the point of your 2nd bit of code?

[white thicket]

Okay wait a minute

[white thicket]

So firstly I want to change this value in game

This is the construction script

and just for testing I connected the set value to event begin play

[faint pasture]

Why? Construction script has already ran by this point

how do you know the parameter isn't being set?

Are you 100% sure your material works and the param has that exact name?

[white thicket]

See if I change value in the blueprint it works But the value is not changing when I am in game

[faint pasture]

Why would it change in game, you only ever set it on construction script

when do you want it to change?

[white thicket]

I have created a functionality using line trace so that when the boat is on ground I want to set the value to 0

All thing is working properly just the value is not setting up to 0

[frigid summit]

hi guys how do add space between waves in here

[white thicket]

Just use delay🙂

[frigid summit]

a space mean a physical distance

[white thicket]

Oh sry I think you wanna say time between spawning🥲

[white thicket]

So what should I use

[gentle urchin]

Im confused by wave being inner loop

Id think wave would be the outer loop, then some unitperwave as the inner loop

Adding offset in the outerloop

Displacing waves

[frigid summit]

i didnt understand where should i place the offset

[low smelt]

Is that script that is setting that parameter as a result of the linetrace within the same BP and pointing to the same exposed and instance editable variable?

[white thicket]

If i didn't use construction strip and use the same code in blueprint then It is also not working

[low smelt]

I think I see the problem, you need to run the same node that you are running construction, Set Scalar Parameter Value, when you are setting bouyancy value to 0

Simply setting it to 0 will not propagate to the value on the material because you are only doing so on construction

[white thicket]

Okay let me try

[faint pasture]

you're setting the variable buoyancy value

you are never telling the material

[white thicket]

I think I solved the problem

I was using a material instance on my mesh. When i used the base material it worked

[faint pasture]

how, you were still never setting that parameter value anywhere except the construction script

[white thicket]

but it is working now 🥲

[faint pasture]

Are you doing this?
#blueprint message

[white thicket]

wait i will show with a video

no same as earlier

[gentle urchin]

Would be handy if you could take a material parameter by ref

Or pass in a ref*

[faint pasture]

You don't want the GPU to be asking the cpu for the parameter every draw

just feed it what it needs when it needs it

Although I don't know if parameters only live on gpu or also live in cpu and are mirrored across, dunno

[gentle urchin]

Might be able to use the field notify stuff for this actually. Or just wrap itnin a function like a sane person

[faint pasture]

or just don't have buoyancy be a variable on the actor if it's only there to be fed to the mesh

[white thicket]

yeah didn't work With variable

It is working when I use this code

[faint pasture]

show ALL of your code

[white thicket]

(right one is from event graph)

[faint pasture]

this isn't helpful. When is the 2nd part called?

[white thicket]

left is from construction script

[faint pasture]

also you're feeding it 0.0, is that intended?

and right is from?

What event leads to the right version?

[faint pasture]

ok and does it act like buoyancy is 15 or 0?

[white thicket]

See let me elaborate I just want that the value of bouyancy comes to 0 when I play the game but right now when I play the game the bouyancy is not setting up to 0

[faint pasture]

might be a dynamic material problem

you said if you use the master it works correctly?

[white thicket]

I removed all code from event graph just construction script is there now what i need to do

bouyancy value is 15

[faint pasture]

ignore the construction script

get it to work on begin play

construction script runs at editor time

begin play runs at runtime

[white thicket]

Okay let me use that

[faint pasture]

[frigid summit]

hi after i added a space in here there is each wave hold one coin how do i make each wave hold random range between min and max number

[low smelt]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Math/Random/RandomFloatinRange/

[white thicket]

It worked if I use event tick

[low smelt]

yah but youd be doing that ALOT so I wouldnt recommend that, you only really need to do it the once

[white thicket]

Yeah, Also the game is for mobile😂

[low smelt]

just fuddle with your logic to make sure its only doing it when it reallys need to

you could do it when the boat object interacts with the actors you care about, like when it collides with the water or with terrain

[white thicket]

Yeah I think i should add the set scaler parameter directly instead of using variable when it hit the landscape

[frigid summit]

here is my blueprint it still some waves hold one coin

[bright hamlet]

How would you go about for a PC Game?😅 fairly new to to engine but love to experiment

[white thicket]

If I am able to make game for mobile the it is easier for me to make for PC as mobile is a tough platform specially for mobile

[bright hamlet]

Any suggestions and tips to follow? Besides the last hour of this convo 😉

Or a video even 🙏

[white thicket]

For which platform you want to make?

For PC or Mobile

[bright hamlet]

Windows 😊

Or what ever the clients run ^^ on their pc

[white thicket]

Yeah then there are tons of video available

[white thicket]

https://youtu.be/k-zMkzmduqI?si=37xIzMHpY0YHqSIf

[frigid summit]

nice course

[white thicket]

This one is good

[white thicket]

What method should I use instead of this

as many says it is not a good choice

[haughty iron]

In the game mode, create the widget you have there, save it as a variable, in the bp boat get a reference to the game mode, get the ui variable and set the boat reference, could also do the create widget inside the boat so you don’t have to cast but I prefer creating widgets inside a central location

[white thicket]

I need to use casting stuff as there are many variables

Yeah I can create widget inside blueprint

then I didn't need to cast\

Okay let me try

[bright hamlet]

I’d love some 🙌

[white thicket]

This one is too good

see his channel there you would find videos regarding unreal

that are very good for beginners

[bright hamlet]

Will do! I’ve compiled over 200 videos already, some outdated and some not but work in progress with learning 🙏

[dark drum]

Something like this. You can make multiple managers for specific actor types or stick to a single generic one but either way, managers are a great way to keep track and get references to actors you need at runtime.

https://youtu.be/RygVokx-mzk

[white thicket]

Thanks I will take a look on it

Is doing this is also not good?

[white thicket]

Just casting once

[dark drum]

No.

[white thicket]

So I can go with this?

[dark drum]

The cache value could clear at any point (the following tick onwards) meaning wherever you have the var pins connected to could end up with a null ref because it's not on the same execution path.

[dark drum]

What the video I sent you on making an actor manager. 😉 the knowledge provided in that will level up your understanding of getting references to stuff and help you out when you start to make complex systems. 🙂

[white thicket]

Yeah I will take a look on that when I will make big complex systems but in this project i just want to cast to my boat only

[white thicket]

So i think I should go with this

[white thicket]

Bru

wait let me watch your video first

[dark drum]

Sorry lol. Understanding makes doing anything easier. 😛

[white thicket]

Yeah I understand

[dark drum]

Just trying to help prevent you wasting time setting something up that's not actually fit for purpose. 🙂

[white thicket]

Yeah I want a simplest way as my game is for mobile and less complexability means more performance

[dark drum]

An actor manager type thing is the way to go if you need to pull actor refs out of thin air. 🙂

[maiden wadi]

Nothing wrong with the GetActorsOfClass

@white thicket But I wouldn't mix the execution lines, just call GetActorsOfClass on the button press.

[white thicket]

On each button pressed?

[maiden wadi]

How many boats are you planning on having?

[white thicket]

For now one

[bright hamlet]

And if more than 1? 😅

[white thicket]

this didn't look good though

[maiden wadi]

How many boats are you planning on having if shit goes insane and you have more than one in four years?

[white thicket]

Okay if I want to use more than one then 😂

This cast system is really 😩

[maiden wadi]

Cast system?

[white thicket]

means casting to blueprint is not good

[maiden wadi]

Nothing wrong with casting.

[white thicket]

I should add the widget inside the blueprint

and then no casting

[maiden wadi]

Except the cast you'll need to tell the widget it's owning thing.

But either way. The GetAllActorsOfClass is fine in specific cases. Just don't use it on the basic Actor class and you'll usually be fine. The World holds maps of actor classes to a list of actors. So pulling that list is pretty quick if you only have a few of that actor type. It only really gets unweildy at a couple hundred actors or more on tick and that's largely due to the array allocation cost.

[white thicket]

Wow that much knowledge

[gentle urchin]

We've been at this topic about > 500 times

At some point one just checks the source to see whats actually going on

[white thicket]

Oh😂

[gentle urchin]

'Just' is ofcourse an oversimplification for some of the source checks... they can be quite tricky to track sometimes 😆

[bright hamlet]

😂

[abstract schooner]

Hey guys,
I have in my level several DataLayers that get loaded and unloaded at runtime depending on the players approximation tot he buildings. However I notice that everytime the datalayer get's unloaded and than reloaded a second time it seems to load everything in their original state? As in certain actors don't seem to hold their chnged variables? Is there a way to circumvent this?
For instance, a bool set to true on an interaction reloads as false, or an inventory of a chest get's emptied on reload of the Datalayers?
Any tips on this or resources to read/learn about?

[dark drum]

You need to implement a save system to save the data when it goes to unload and load/applies the saved data when it's loaded again.

[manic vessel]

I have this function to Move the Character with the VR players camera in the X & Y, and its working great, But Im trying to build it for multplayer and its a stuttery mess and the actor is not even moving in the world , anyone know How I can fx this .(runs on tick)

[white thicket]

This looks good but the problem is this

[manic vessel]

Why are you just asking for the array index of Zero. , do a for loop instead

[white thicket]

This?

[manic vessel]

yes

[white thicket]

i have to connect with array element right?

[white thicket]

If I want to use multiple boat(just for example duplicate the boat bp )

[manic vessel]

add a is valid to and pull the ref from the loop to use

[white thicket]

Can i convert actor class to array?

so that I can use multiple boats

[manic vessel]

an array is not a class. its an array of what classes in the array

[white thicket]

so what I can use so that I can use more boats

[manic vessel]

are your boat actors created from a boat base actor?

[lethal pollen]

Hi!

Is this the way to get the integer part of a float number?

Or maybe there is a function like fraction.

Thanks!

[manic vessel]

Truncate?

[white thicket]

See I just have a pawn blueprint

[manic vessel]

?

[manic vessel]

My Mistake I didnt see you were in the UI editor, thought you were just trying t set a bool on all boat actors in the world.

[lethal pollen]

I don't know. If I ask it's because I don't know the answer.

[white thicket]

Yeah just changing bool values

[dark drum]

if you have a float of 32.543 and truncate, it'll give you 32. (as an example)

[lethal pollen]

Thank you.

[frigid summit]

hi do you know why some waves has one coin even though the random integer of the third for loop last index is min 5 and max 9 and overall is adding third for loop make this happen i mean random int between min and max coins per wave

[dark drum]

It's probably down to multiplying the y index of the 2 loops multiplied again by 1200. They are most likely just spawning outside of the area you're looking at.

[frigid summit]

it still not ouside the area but the randomniss between min and max not working correctly idk why

even some coins are just two

[dark drum]

Well they'll be spawning, just not where you think. If the 2nd loop is 3 and the 3rd loop is at 5, that's 15*1200. That means it'll be spawning at 18,000 on the Y.

[frigid summit]

i even set it to 400 and still

but the overall y seems good if i set it to 1200 the y go outside the mapjust the randomniss between min and max is the proplem

[versed sun]

can you Get All Actors of that Class , and print the length to see how many spawned

[frigid summit]

ok i will

[versed sun]

maybe spawning inside eachother

[frigid summit]

more than 200

[versed sun]

you can select them in Outliner , and press F to focus them in viewport
see if any are in same spot

[frigid summit]

the min is 2 and max is 4 the number of waves are 24 so there is definatly something wrong here

[frigid summit]

they all in diffrent spot

[manic vessel]

Why does this work in standalone but not as a client .

[frigid summit]

but the number after 100 they seems to reset at the first location so 101 is the first coin

[spice viper]

It's a server event, that only runs on the server? Also, some camera position information isn't replicated (that could only matter between clients though)

[manic vessel]

It was initially a local event before I started to try and make my system work in multiplayer, . Because when I connect as a client this system just stutters as I try to move but the chacacter is not moving in the world .

So I thought I would need to do this on the server, as that probbaly trying to correct the character worl position each time I move

[worthy jasper]

You do need to set the variables on server

But when your making use of them, you need to replicate that to clients

As stated earlier you really shouldn’t be trying to access camera components server side, you should pass the values you want to the server, set your variable, and then replicate what needs to be done to the clients

[young meteor]

Is there an easy way to clear/remove a spawned system before it has finished?
So when some event happen make the effect disappear?

[manic vessel]

This Replication stuff is new to me, not sure How I should do that,

[worthy jasper]

Some good tutorials on YouTube for it! However, you would make a new custom event, set the replication to “executes on all” and then move all the logic from your exec 1 then statement, to this new event

Then in your exec 1 call this event

[manic vessel]

Im working BP ONLY, I don't see the on all option.

[worthy jasper]

Sorry it’s called multicast

That’s what you want

I was thinking what it says on the node 😂

[latent venture]

I am trying to makee in such way that in the first room, all doors are opened, And it executes exactly how I want when the first room has only 1 door ( second picture), but if the first rooms has 2 doors, one of them teleports to the other door and stays close ( third picture) and in the 4th picture you have the other part that should be the second door, but it isnt there, do you have any ideea on how could I solve this? I tried marking render state dirty only on the last instance but doesnt solve my problem 😦

[manic vessel]

This needs to run on tick so should I just call this new event in the tick now?

[worthy jasper]

No a multicast needs to be called by the server

So you would call your new event inside the event you showed in your screenshot

[wise ravine]

Hi, I'm starting to learn about OOP and paradigms so I can learn Blueprints. Are these notes accurate?

[manic vessel]

Is the server going to run this on tick also? it needs to be constantly updated , not a one time event

[worthy jasper]

Yes it will, with a multicast the server will execute it locally and tell all clients to execute it as well

So if you need it on tick, as long as “room scale server” event is firing in on tick it will fire and update

[manic vessel]

This did not seem to change anything 😦 Not sure if I understood the assignment .

Also tried this . But My character is Not moving still . its like its trying but keeps being reset

[jade haven]

Hey guys, i'm currently using ue 5.3 and i am trying to make AsyncTickPhysics plugin to work in my current project, in the pawn i inherited the asynctickPawn class and i enabled it in the project settings aswell, but still no luck on making it work, what am i missing?

[bright hamlet]

Does it matter if “Has authority” is directly plugged in or it’s the same not sure if it’s missing the connection in beginning (still noobie trying to learn)

[latent venture]

@dark drum could you take a look in my problem please?

[dark drum]

It looks like your using two ISM components for the same mesh. Not sure if that's the issue though. How come you're using ISM for the doors? It would be far easier to use an actor that you just spawn where you want and have it handle opening/closing in local space.

[south ginkgo]

Hi, I want to make it that my projectile bounces but only on impact with certain meshes. I assume the issue is that it hits the collision before knowing what kind of mesh it is. If anyone has any ideas or solutions, it'd be greatly appreciated🙏

[lofty rapids]

so if othercomp is == to what crystal, then apply the impulse, but if not your spawning ? so if it hits something that is not it, will it spawn ... ?

is what your trying to spawn an impact point or something ?

[lofty rapids]

is it hitting the something that is not the crystal and going to true ?

[south ginkgo]

Well in short, we want it to spawn a sort of 'health zone' for the player upon impact with any other actor and destroy itself, however if it were to hit the crystal, we simply want that to be able to bounce back.

[lofty rapids]

and it's bouncing off other things ? or whats it doing ?

[frigid summit]

thanks now its really begin to look like endless runner

[south ginkgo]

When using a print string connected to the 'other' in the event hit, it is able to detect the crystal itself. But for some reason, it still acts as if it was false.

[lofty rapids]

did you try a cast ?

[lofty rapids]

so the == isn't working ?

[south ginkgo]

Basically that, so it always goes to false, despite hitting the crystal

[south ginkgo]

We did attempt a on collision begin overlap with a cast to with the crystal, but it seems that the impact happens too quick for it to register

[lofty rapids]

i mean just try to cast instead of ==

i don't know if it's different, but if it registers as the correct bp...

then the == isn't working, and you need a way to check that

[south ginkgo]

Alrighty, I'll try that thanks

[sturdy verge]

I'm struggling to set my Canvas Widget to 4k, in play mode it always has 1920x1080 instead of 3840x2160

[autumn patrol]

This is a complete novice question, but I have an object I'm creating that the player spawns in on a button press. I need this object to take a string to choose what code it uses, I know I can use branches and an == node to choose this but that would take like 10+ branches per decision and I have 5 variables like this, is there a better way to replace the branches so I only have to do 5 so it's 1 for each variable

[sturdy verge]

Create a Enum for the choices and use Node EnumSwitch

[prisma crag]

Blueprint Runtime Error: "Accessed None trying to read property Unit". Node: SetText (Text) Graph: EventGraph Function: Execute Ubergraph Target Window Slots Blueprint: TargetWindowSlots

Keep getting this error message, This is the code it's complaining at (I can send more in regards to what it is it's trying to reference) and all it's supposed to do is put the names of potential targets of attacks in a turn based game, Any words of wisdom?

[autumn patrol]

Thank you, I'll look into that

[prisma crag]

It worked perfectly fine last time I worked on this project and I haven't touched this specific area of code at all

[autumn patrol]

Wouldn't this require you to make it instance editable and expose on spawn, also to set it as soon as the game starts/it's spawned?
I'm taking about the units var

[lofty rapids]

unit is empty

[keen jolt]

FIXED: Had to make the Patrol Location a instance editable var and then reference it in my Blackboard. The guide never mentions it :S.

[prisma crag]

The unit is instance editable, and exposed on spawn

It's also been referenced in a whole bunch of different blueprints, and those are fine

[autumn patrol]

Add a print to the preconstruct before the set text and plug the unit into it and see what it says, if the value isn't what you want it to be you'll need something to set it

[prisma crag]

Print string, right?

or text

[autumn patrol]

Either will do it but I prefer to use print String for variables

[prisma crag]

And this'll just print it in the dev console, right?

Sorry for the questions, as I said I'm quite new to Unreal Engine as a whole--

[autumn patrol]

It should but I check the top left of my screen whilst running the game, it just makes things easier for if I need to know when a value is happening too

[prisma crag]

It still came up with the same error, and nothing appeared at the start

[autumn patrol]

Break the link to set text for now, as we just want to test the unit var with the print. Once you do the required action it should print something even if its saying there's no value in unit. If that doesn't work you're going to have to set the value, you can do this by just setting it before you print it for now to see if that's the issue

[prisma crag]

Wait, sorry, I managed to figure out the Unit problem-- The code made to populate the widget with the Units names wasn't plugged in for whatever reason

my apologies

[autumn patrol]

Don't worry lmao, I'm sure every developer has had an issue where they spend hours trying to troubleshoot their code only to find out it works they just didn't plug in one thing

[prisma crag]

Yeah, it's happened to me alot in the span of like, 5 days

In any case, thanks for the advice! Now I just gotta figure out the issue I had in the first place

[autumn patrol]

As one newbie to another, print String is your best friend for troubleshooting and checking if code will work. Just plug it in wherever you think the code is broke and you'll see where it is actually broken

[autumn patrol]

Is the error saying the same thing?

[prisma crag]

Nah, it's not even giving me an error.

I'm making a UI for a JRPG style game, and rn I'm working on making it so healing spells target allies

which is working, though now the normal attack is only targetting allies.

[frigid summit]

hi guys is it possible to connect loop body to random integer in range chatgpt says yes

[prisma crag]

try converting loop body to an interger/float

[autumn patrol]

If there's no error then the code should be working, it's probably just unfinished, when you set the text where is the result meant to show?

[prisma crag]

This is the code I've got for it, and I'm sending it to my HUD

I think it's moreso a logic error than anything else

[frigid summit]

how do i do this

[autumn patrol]

Nothing shows up? Have you added it to the parent/screen after you created it

[prisma crag]

things do show up, one sec I'll get a few screenshots to explain it better

this is what it looks like when I press a normal attack (Fey, Gideon and Graystone are the names of the playable characters for it)

when I press to use an attacking spell, it lets me target the spiders as it's supposed to

ok wait a sec I'm getting more errors

[autumn patrol]

And you want it to target allies when you do a healing spell?

[prisma crag]

It was doing it before, It's just evertyhing has decided to stop working abruptly

I'm not quite sure why, I'm currently double checking everything

[autumn patrol]

Have you done this code but added a check for whether it's meant for allies or enemies then run this code replacing the class and reversing the select so allies are true and enemies are false

[prisma crag]

That's what the Class is Actor of is for

The ability varible is the spell it's trying to use

if it's an offensive spell, it'll get the names of the enemies for the target list

if it's anything else, it'll target allies.

Which I'm now realizing may be why the attacks aren't working as intended

[autumn patrol]

So this part currently works as intended for the UI side at least?

[prisma crag]

the magic, yes. normal attacks which are separated from the magic ones? No

[autumn patrol]

What is it showing in the UI when the normal attacks is selected?

[prisma crag]

it shows, and targets allies

[autumn patrol]

Can you send screenshots of both the code for the normal attacks and what the UI does in game

[prisma crag]

this is what the UI does in game

as for the code

I'll need to send it in parts, since it's quite alot

that's for the attack itself.

As for the code to display it, one moment

[sturdy verge]

random guess, is the ui at any point outside of the screen? This prevents update

[prisma crag]

If it helps as a reference to what I'm basing the code off, I'm following Ryan Laley's JRPG tutorial series

[prisma crag]

Nope, it's always onscreen

[autumn patrol]

The first one you showed like 15 minutes back was magic right? What's inside the attack function

[prisma crag]

This is the entirety of the melee/ranged code

the magic code I haven't sent yet, though it's similar to this

this is the Magic stuff

[autumn patrol]

Can I see what's inside the "attack command" function. Specifically which part is set to show the UI targets

Because if its only showing allies I have a feeling that the wrong array is plugged into the create widget

[autumn patrol]

The code should be similar to this except you have no need to get allies, class or even the select, just plug the enemies directly into the for loop

[prisma crag]

Attack command isn't set as a function, it's just a custom event. As for the UI targets the code that has the party/enemy units attached to the For Each Loop is the code that shows the available targets. Here's the full version, if that helps

[autumn patrol]

So its using the same code as magic to show the targets in the UI, if so its showing the allies in the UI because offensive magic is coming back as false, you need a check to specify its for a normal attack and then have it select the enemies as the target

[prisma crag]

I see, so essentially do the same thing I did for offensive class and just have it search for normal attacks too

[tacit vale]

how do i get my projectile to always hit center? first is long range shot, second is medium and third is close range. I have all gravity turned off and the attached code is for my gun

[autumn patrol]

Yup that should work, it's only showing allies because it isn't offensive magic

[prisma crag]

Got it.

[faint pasture]

How far is the gun offset from the camera?

[prisma crag]

Ended up just switching the condition to searching for Support magic, though it ended up in the same result I'm looking for anyways, thanks for your help!

[autumn patrol]

That way is probably for the best, it uses less code for the same result

[prisma crag]

Yeah, just had to swap offensive magic's base for the support one

[tacit vale]

how do I find that out?

[faint pasture]

You made the thing

I mean is the gun right in front of the camera or offset down and right of it by a good distance?

[tacit vale]

its offset down and to the right

[faint pasture]

That's not crazy extreme, show your math for how you determine in what direction to shoot the projectile

This is what you're dealing with

[tacit vale]

Apologies ,I am new to development. I believe this is how im determining projectile direction:

[frigid summit]

hi is it possible to connect loop body to random int chat gpt says i can

[lofty rapids]

that is a pure node, what do you need the number for ?

[faint pasture]

ok I bet I know your problem

your crosshair isn't centered

your aim point is the top left of the crosshair texture

that doesn't entirely fix the problem but that's a step

[frigid summit]

for random integer to randomize my obstacles but why chat gpt says its possible

[worthy frost]

@tacit vale you need to go from the camera adjusted to the gun location

it will always be dead center then

[frigid summit]

it says this Within the loop body, use a "Random Float in Range" node to generate a random float.

[faint pasture]

and do what with it?

that'll give you a float

what do you want to do with it

[maiden wadi]

Destroy should work. There should also be a call somewhere to stop the system and let it auto destroy though.

[frigid summit]

basically randomize my obstacles but i cant randomize it using index and not random float sorry random int

[faint pasture]

Sure you can. You've got the node that generates the random number. Now do something with it

btw that random int is between 0 and 0 so it'll always be 0

[frigid summit]

yea i know but how is gpt 4 saying this isnt that obviously wrong or i can somehow connect it to loop body

[faint pasture]

start by printing that int

[lofty rapids]

the loop body has an execution

the random is a pure node

you can just use it like a variable

[worthy frost]

@frigid summit don't use gpt.... it doesn't know unreal

[tacit vale]

so I need to change first person camera to my rifle?

[frigid summit]

oh ok

[tacit vale]

I am using the UE provided crosshair, I will see If I can adjust it

[frigid summit]

i thought i could

[worthy frost]

@tacit vale what is arrow ?

in first person you shoot from the camera

but adjust the projectile to fire from weapon towards camera

[faint pasture]

#blueprint message
Do you understand the problem here?

[tacit vale]

arrow is where my projectile comes out of

[lofty rapids]

the data and the execution are two different things, you got the data a random number, but you are not executing anything, or using the data

[faint pasture]

camera and projectile spawn location are not at the same place

so flying in the same direction will not end up with them hitting the same place

[worthy frost]

@tacit valegive me a second ill show you how to do it

[faint pasture]

but you aren't doing yourself any favors by having your crosshair off center

[tacit vale]

Gotcha, I am gonna try to see if I can center it then

[faint pasture]

Either draw the crosshair where the gun will hit, or adjust the gun aim to aim at the same TARGET POINT as the camera is

[faint pasture]

show how you're drawing crosshair

[faint pasture]

you need to subtract half of the crosshair dimensions from the X and Y

0,0 on a texture is top left

not center

[worthy frost]

why you not using a UMG widget for the crosshair, much simpler

[faint pasture]

or maybe feed 0.5 into the texture U and V

that might do the offset for you

[gritty wraith]

Hello, it would appear that making HTTP requests for API's as gotten quite impossible, that is if you wanna do it without having to spend MONEY on plugins, so i'm here with tears searching for hope

[faint pasture]

Subtracting 8 (half of texture size) from X and Y will center you

[tacit vale]

not sure what that is, I was following a game build guide and he used UE crosshair

[tacit vale]

this subtraction is done after the division or is this replacing the division?

[faint pasture]

That's fine for now, do a line trace down the centerline of the camera to confirm it hits in the same place the crosshair is

[faint pasture]

after

or 16 before

[frigid summit]

basically i got array of my obstaclls and i want to for loop that array and spawn after for loop from first index to last index and random from min to max which min is the first index of the array and max last index

because i have diffrent types

[faint pasture]

ok so do that

[frigid summit]

how

[faint pasture]

get element from the array based on random number

but you're kinda reinventing the wheel here

there's foreach loop on array and also shuffle array and also get random array element

[lofty rapids]

i c , so you want to pick an index from the the array ? a random one each body of the loop ?

[frigid summit]

ok i forgot shuffle exsist

[frigid summit]

yes

[lofty rapids]

shuffle and a foreach probably work like mentioned

[faint pasture]

#graphics

[lofty rapids]

and you don't want duplicates ?

[worthy frost]

@high spade #materials

[dreamy kindle]

Any advice if I should start with blueprint or c++ when learning coding for multiplayer fps games in unreal ?

[bitter star]

Is there a way to change the sensor size of the Virtual camera to make it vertical? Looks like the values are locked so I’m thinking maybe through BP?

[worthy frost]

@tacit vale so you need to subtract your cam loc from your weapon loc and produce a rotator, this is your rotation for the projectile, then you fire from the weaon passing this rotation should be towards where the camera is focused

[frigid summit]

no its okay because its obstacles in endless runnner so its okay to have that but the main proplem here that it will overlap with my coins it wont be in the rest of the map like i would because i made the same logic for spawining coins same as obstacles

[lofty rapids]

#multiplayer #cpp

it's best to do multiplayer in c++ if you can

you really want that performance

[tacit vale]

I tried subtracting 8 after the division but bullet flies much more to bottom right now. I kept adjusting value but it will continue to fly to top left or bottom right depending on distance

[faint pasture]

The bullet will hit low and right based on the spawn point being low and right of the camera

so now you got the 2nd problem

you can't start in different places, go in the same direction, and hit the same place

quick illustration:

This is what you have

camera and gun are offset so same direction = offset on hit points

This is what you want

[worthy frost]

@tacit vale

[faint pasture]

start by tracing down the camera and storing the location as a vector AimPoint

yeah that approach works too, just choosing a distance you want their paths to cross at

note, that'll make you start hitting above and left for shots further than focal distance

offset aiming is hard

[worthy frost]

yeah we use a trace from the camera to determine the focal range

but we use this logic

we cap out at max of 5k though

anything over that we dont care

[faint pasture]

Mathematicall that's the same as trace -> clamp distance -> aim at AimPoint right?

[worthy frost]

yeah but without the cost of a trace

[faint pasture]

how do you know the depth or do you just hit low and right and live with it?

Should only need 1 trace total

[worthy frost]

our focal point is actually adjusted (i just didn't put it here for simplicity)

focal distance*

[faint pasture]

Yeah the whole problem is a PITA, theres all sorts of edge cases like trying to hit silhuoetted targets

[worthy frost]

thing is normal projectiles wont fly true anyway

aftrer x distance you expect them to be off

[faint pasture]

you guys use projectile movement component or make your own system?

[worthy frost]

depends on how realistic

we use projectile movement for projectile weapons

hitscan for most weapons though

[faint pasture]

idk why it doesn't have a line traced fallback, does it seriously sweep for everything?

[worthy frost]

launchers and snipers are projectiles

we dont even spawn the projectile if something if something is close

[tacit vale]

I am a bit overwhelmed, can we get in a VC?

[faint pasture]

I've had great results with my own projectile system that basically does projectile movement through line sweeps but without a collider. At high enough speeds it basically "becomes" hitscan

[worthy frost]

@tacit vale implement my logic and see how it behaves

can copy paste the nodes

and just replace with your camera and arrow

[tacit vale]

Do I replace camera rotation or loc with arrow?

[worthy frost]

i commented it

[tacit vale]

I will try to get it to work, thanks for the help @worthy frost and @faint pasture

[fast compass]

I have a base blueprint component with a bunch of variables - Image 1

Then i make a child blue print component from this base blue print component, and I wish to be able to edit the default value of those variables, but I cannot see any variables showing up under the variables tab in child component - Image 2

I can however access them from the blue print graph in the child component - Image 3

Is there a way to expose the default variables to the child component?

Edit: I noticed discord messed up the order of the images a bit, I hope its understandable still

[maiden wadi]

Still not sure why that's disabled by default. :/

[lunar sleet]

it's not necessarily needed, you can just type get and get it, more aesthetic than anything, if you understand OOP to begin with because UE 😛

[fast compass]

Omg! Thank you so much! I was going crazy..

[fast compass]

Out of curiousity, can you elaborate this? If I have an actor or other variable that I expect may differ in children, why would it be preferable to set the value of that variable in Begin Play rather than just editing the inherited value?

[lunar sleet]

it wouldn't, I missed the part where you wanted to edit the default 😅

thought you just wanted to access said vars

[fast compass]

Oh, I see 😄 Yeah I need to override a bunch of default values.. Glad it exists at least 🙂

[lunar sleet]

the UE gods do such things often, like only half-exposing certain things to bp, if at all

[fast compass]

Yeah, makes sense for most scenarios

[maiden wadi]

IMO, I've never had a case where I don't want to see parent variables. If your BP is that massive that it's an issue, you should consider a few less inheritance chains or some better data structures. O.o

[surreal peak]

I gotta say, in the past 10 years, I maybe enabled that 2-3 times.

And I think 2 of these 3 times was to make a picture for the Compendium

[maiden wadi]

Once for every new project.

[surreal peak]

Na honestly, I never enable that. Never had a need for it.

Not saying it's not useful though.

I often use the "only show changed properties" setting for the Class Defaults fwiw

[lunar sleet]

then only one bp in the entire project would show them no? 😄

[maiden wadi]

Those settings are global.

[queen heron]

I'm having a little bit of a confusing issue with the control rotation

the yellow arrow points towards the moving direction, and that blue arrow is the movement input

[lunar sleet]

oh right 😅

[queen heron]

normally the pawn is supposed to look at the movement input and move towards that direction

here's my blueprint setup

am I doing something wrong?

[maiden wadi]

Any reason you don't just use the velocity rotation stuff?

[granite elk]

I am attempting to use the insert array node to put specific variables into the array based on use of random integer in range. 2 questions, will adding an item to an array automatically know to not fill an already filled element of the array? once insert is utilized is the array updated or do I still need to set it myself?

[queen heron]

you meant the Orient Rotation to Movement option?

[maiden wadi]

Yeah I think

[queen heron]

if so, then there's a reason I'm not using it

I need my character to have its directional movement dependent on its facing direction

[maiden wadi]

What are you doing for the rotator here?

[surreal peak]

I am attempting to use the insert array

[frigid summit]

hi guys why is the overlap dont happen in here and even inside the static mesh actor itself

[queen heron]

the one with spring arm?

its what I'm using to get a proper direction input

when Rotate To Movement Input boolean is false, the control rotation follows the spring arm's world rotation as it should

but when I set it to rotate to the Move Location vector

it is not following it

[surreal peak]

hi guys why is the overlap dont happen

[maiden wadi]

I mean here. What are you doing for the rotator setting the control rotation?

[queen heron]

I'm trying to make it rotate towards where the Move Location vector is

the blue arrow is the debug mesh for it

[frigid summit]

@surreal peak basically im trying to spawn set of obstacles that are in the array and if the some class overlap with other one i destroy it but i cant do that as for the other part for event graph its alot man do you really want it

[queen heron]

one sec

[surreal peak]

:P could you answer that inside the thread?

[queen heron]

didn't realized I hid the look at rotation node

[frigid summit]

no

i cant

[surreal peak]

Oh, are there rights not allowing you to?

[queen heron]

ding

[frigid summit]

yes

[queen heron]

so yeah, am I doing something wrong? or did I just stumbled upon a blueprint limitation?

[surreal peak]

Good to know. Gotta annoy our admins for that.

As far your question: In theory, if the collision is set up correctly in your Actors, they should overlap fine.
Your code is always checking the same 2 Actor instances though, since you are grabbing them via GetActorFromClass from the Scene.

[thin panther]

wait when did we get threads 👀

[queen heron]

I'mma try using the actor to set its rotation and move the pawn along its forward and right vectors

really curious if this works...

kinda

but now the movement direction is a hot mess

actually no, forgot to check the boolean on the select node

its the exact same situation as control rotation

except the actor actually rotates this time

[lofty rapids]

whats happening thats not working ?

[queen heron]

I wanna have a toggle system where the player can switch between strafing to the moving direction and rotating to the moving direction while following the facing direction

this setup works just fine when Rotate To Movement Input is disabled (custom bool variable I made)

but this just breaks the forward and right vectors

[surreal peak]

fwiw, you probably want to null pitch and roll on that

[queen heron]

hmm

lemme try

[surreal peak]

Cause your rotation is only around Z for this stuff

Otherwise your character starts tilting

[queen heron]

still nothing

maybe if I use a rotator variable for the world direction movement input?

so that the movement direction still smoothly changes when pressing other direction buttons while the control rotation/actor rotation is set without issues?

[gentle urchin]

I kinda like it 😶‍🌫️

[surreal peak]

I'm honestly still a bit lost on the requirements here. You have 2 modes:

1. Strafing, which usually means that the Character looks into the same direction as the Camera and A or D will make them walk left and right, without rotating away.
2. Rotation to moving direction, so without moving my camera, pressing A or D will cause the Character to rotate towards the world diration of what A and D is pointing to.

Is that correct?

[queen heron]

yes

[surreal peak]

Okay, but then I'm a bit lost why the combination of "OrientToVelocity" and "UseControlRotation(Yaw)" doesn't solve this

[queen heron]

and I still need to use the camera's pointing direction for the head to look towards the camera's way

[surreal peak]

The Head is Animation stuff

That is done in the AnimBP

[queen heron]

I don't wanna have this simple thing where the movement direction doesn't depend on the actor's whole facing direction

[surreal peak]

Here is how this setup should theoretically work.

• SpringArm uses ControlRotation
• Strafing: UseControlRotation(true), OrientToVelocity(false)
• Non-Straing: UseControlRotation(false), OrientToVelocity(true)

[surreal peak]

You gotta explain what you mean, cause "whole facing direction" is no general known term, at least not to me

[oak gust]

what is the correct way to play a anim montage for example an animation where the character is attacking with his weapon but also play the run animation only for his feeth (because I allow the player to attack during moving)

[surreal peak]

If you want the Character to be rotated towards the camera, you gotta use ControlRotation on it during that time.

[queen heron]

so basically, you have the character standing and is faced towards lets say North
then when you press the button that will move the character to the opposite way, it won't just move in a linear way
it will do a little U turn

and thats exactly what I'm aiming for

[surreal peak]

Shouldn't you be able to control that via the RotationRate on the CMC

[queen heron]

the rotation rate is for how fast the character should rotate to the movement direction only, isn't it?

[surreal peak]

Hm, I think I see what you want now. You want it to keep moving into the direction it is looking, but at the same time rotate that direction.

[queen heron]

yes

so the issue I am facing right now is some sort of a cycle

which break the directional vectors from the control rotation

[surreal peak]

Yeah thinking about this for a minute.

[hot lintel]

Hi. Can't figure it out. I have top down project. I want inverse movement. example: If i click top of the screen character moves down, if i click left characters moves right etc.

[queen heron]

how do you tell the character to move to the location you're clicking?

[surreal peak]

Try to make threads when answering users

[hot lintel]

yes

[surreal peak]

We are test running it in #blueprint atm

Not a must, just a suggestion of course

[queen heron]

right, to keep the channel cleaner

[hot lintel]

how do you tell the character to move to

[surreal peak]

So fwiw, you could add movement input into CharacterForward direction

And rotate the Character itself without ControlRotation

[queen heron]

my biggest guess is that I would need to use a rotator variable to have the movement input working the same way as the control rotation

and rotate the actor separately

[surreal peak]

Yeah, so, if we say that this is all only true in that given mode, and not in any other, then you would always add movement input into forward direction, but use the Direction you pressed to Lerp the ActorRotation of the Character towards the matching ControlRotationDirection.

[queen heron]

gonna try it out

it might take a bit to set it all up

[surreal peak]

It's just an idea

I haven't done this setup yet, or at least in a while, so there might be answer solution

But I would try to keep ControlRotation as it is and leave it for controlling the Camera

And only use it to get the Forward, Right Directions that you want to Lerp the Actor Rotation to for that mode.

[frigid summit]

man how do you answer double threads and blueprint channel at once thats imposible at least for me

[surreal peak]

On the left side, where you see the channels, you see the #blueprint channel, and the threads you are part of.

You can also see all the current threads of this channel if you click on the thread icon at the top right of Discord.

And if you are in a thread and it takes your whole screen, similar to a normal channel, you may also click on the 3 dots at the top and select "Open in Split View".

Then you can see #blueprint and the thread.

I know, we all gotta go the basics of threads after they already exist for so long.

[frigid summit]

i didnt know i could do this good to know

[queen heron]

I think I figured out the solution

[surreal peak]

Does it involve any of my suggestions, so I can feel good about myself?

[queen heron]

I've thought about the way you move with the joystick

just need to finish the setup

[wintry talon]

The CleanedObjective array I've been using for saving level completion and loading the level state has been deleting the array items randomly during gameplay and I have no idea what the cause of it is

[queen heron]

there we go

and here's the blueprint setup

it was actually that simple 😅

[dire halo]

Is it possible to respond to FellOutOfWorld from blueprints? To determine what happens when you hit the killz floor? I'm only finding docs for c++ implementation

[sand yacht]

Hi, is there a way to make this run async?

freezes up the engine right now trying to load a map bigger than like 100x100

[queen valley]

arent custom events async?

[sand yacht]

oh not sure, this is running on the construction script. i will check real quick

if i swap it out to a custom event it still freezes my game / engine

but I would like to eventually make this happen in a loading screen like in terraria, minecraft etc.

[queen valley]

thats not cause its not async

it is cause it is on the main thread

[sand yacht]

ah yeah i mean having it run on another thread

my bad

thought that was kinda the same as async

[queen valley]

dont think theres a way around it with bp without plugins

[gentle urchin]

define async

[queen valley]

turns out this plugin is free

https://www.unrealengine.com/marketplace/en-US/product/asyncfunccaller?sessionInvalidated=true

[gentle urchin]

anything async i'd expect not to block gamethread

There's nothing here suggesting it's async or latent in any manner

[queen valley]

wdym

[queen valley]

async can run on one thread wdym

[gentle urchin]

Im not saying it cant

[maiden wadi]

I'd be terrified of putting that in my project. That plugin looks so abusable. 😂

[gentle urchin]

im saying if it do, and is supposedly async, it shouldnt block

otherwise whats async about it ?

if it blockingly runs right now

[lunar sleet]

lol the lengths people go to in the wrong direction, all to avoid using cpp

[gentle urchin]

far longer than the c++ path : P

[queen valley]

async means everything else doesnt have to wait for a function to finish, it can proceed

[gentle urchin]

Exactly.

[queen valley]

but it could still be on main thread

[gentle urchin]

Think we're walking circles here

[lofty rapids]

probably c so it runs faster

[queen valley]

async is not the same as parallel you dont understand

[gentle urchin]

fair claim

[plain egret]

Hey guys so im setting the players view target to this main menu cam so that i can perform level sequences with it and i want to set the view target back to what it was at the start of the game(The players camera) right before i close the level any clue why this isnt working?

[gentle urchin]

you're the only one mentioning parallel tho

Clearly in this case the node is blocking GT, so not much async about it. everything has to wait

[queen valley]

well then a heavy operation is still gonna block the main thread

if not multithreaded

[sand yacht]

so running something on another thread will not block the main thread right, even if its a heavy operation

[gentle urchin]

correct

[queen valley]

yes

[gentle urchin]

you will block on the return to main thread ,

[queen valley]

how do I make a class be always loaded? Is there a way to do this

[sand yacht]

ah cool, thanks guys

[gentle urchin]

but that's hopefulyl minor in comparison

[queen valley]

i would still use cpp instead of that plugin tho

[sand yacht]

i am like a baby when it comes to C++

never used it before

found another one though which looks a little better

[lunar sleet]

Long as it’s accessed periodically, it will stay loaded. Might wanna explain your use case tho

[gentle urchin]

so this is work done on separate thread most likely (sounds like it)

[queen valley]

so I have an actor which contains a reference to a class where it gets variables from that class, but since it is not loaded it says error trying to access property

[lunar sleet]

How are you getting the vars?

[queen valley]

get class defaults node

[lunar sleet]

Are you casting into it or how are you talking to it

[queen valley]

so I have to cast?

there will be like 100 items and then they all have to be loaded

[lunar sleet]

Well you need a ref to it
