blueprint

[grave apex]

I thought everybody was referring to the source string

thanks!

[compact vapor]

how in the world do you get the enhanced input system to rotate the players capsule?
the code works great for all other components, but for some reason the capsule is being stubborn

any ideas?

[lunar sleet]

You don’t rotate the capsule, it’s immovable

You rotate the character itself or the controller

[compact vapor]

new problem, how does one increase movement speed of a pawn?

[lunar sleet]

I’m sure there’s settings on the floating pawn movement component

[compact vapor]

theres max speed but thats just max.
my inputs are from -1 to -1

increasing them with a multiplier does not change them

[lunar sleet]

Is there an acceleration or velocity ?

[compact vapor]

theres acceleration, but i was under the impression that was just for how quickly the player reaches top speed

[lunar sleet]

Yeah that’s prly right

Are you trying to make a vehicle of sorts?

Vehicle movement comp has gradual acceleration and deceleration iirc

[compact vapor]

its as if my inputs at a value of 1 is corresponding to a hard coded speed of moving the character.

character moves at input value of 1, ok..... what in the world is that speed?

also its just a camera for a strategy game

[candid sentinel]

Ok so for a puzzle in my game, I want it open a door after 4 houes have passed.. but I want it to be 4 hour ACCORDING to your system clock. So I've been using the "Now" nodes and comparing them. The reason I want to use the system clock like that, is the solution to the puzzle is to have them change their clock 4 hours into the future. But the problem is, if its 10:000, its adding +4 to that , which is 2:00 but since 2 is less than 10, the door instantly unlocks. should i be using UTC or something? https://gyazo.com/1ed85e831282b33858fbb8d4543fac85 https://gyazo.com/8d9d897651bbd20c8779a4c0a9ef5386

[carmine palm]

Is there a way to make a (not correct phrasing so dont take it as face value) "copy" of bp class object (lets say its a base class object you made) and then when doing spawn actor from class, modify that "copy" in-line before you spawn acto

[lunar sleet]

Ah, just add movement input

Then multiply it by whatever you need to get that speed

[compact vapor]

that doesnt work unfortunetely

any value past 1 doesnt seem to do anything

[lunar sleet]

You can expose certain variables

[lunar sleet]

Show code

[carmine palm]

I know how to do it after. But is there a way to make a ref to a class, modify values for that instance, then spawn actor by that modified class

[lunar sleet]

I didn’t say after

If you expose those variables, then on the spawn actor node you will get those pins

[sweet grotto]

could I have some assistance answering my question please?

[carmine palm]

ohhh

expose on spawn?

or whatever

[lunar sleet]

For #multiplayer ask there it’s your best bet

[carmine palm]

Thanks bro

[compact vapor]

Max speed is 10x default, movement scale on inputs is 500x

yet no difference in speed

[lunar sleet]

And also no, get player controller 0 should almost never be used in multiplayer context.

[compact vapor]

this is because the inputs deal with floats between -1 and 1
so anything above 1 doesnt do anythnig apparently

[sweet grotto]

it still triggers with a listen server tho which confuses me XD

[lunar sleet]

There’s a compendium pinned in that channel that might help

[sweet grotto]

in #multiplayer right?

[lunar sleet]

I can’t check my project rn, but also debug to see what values are coming through

[compact vapor]

when w is pressed its 1

this is how enhanced inputs work

[lunar sleet]

I meant your end values

[compact vapor]

the value of 1 in the enhanced input system has a speed associated with a value of 1 and I cant figure out where that variable is hidding

end values are 500

[compact vapor]

you would expect that a value of 1 at 5000 max speed out be different than a value of 1 at 750000 max speed
but its not.

the movement input is adding like a constant value throughout the function regardless of any increase past 1

the movement input is like "ok we have a value of 1, thats a full input right there, so were moving now"
ok great...... moving at what speed?

[compact vapor]

if someone in this discord can get a pawn with a movement component to move faster than default
I'll give you 5 bicks

beause its not possible.

welcome to unreal engine, where you can change how fast a player can move a pawn...............

[carmine palm]

Does anyone know how I could set my static mesh components static mesh object from here?

or do I need to expose something else

[compact vapor]

cant you just drag off the pin and set the static mesh?

blue pin is an object reference

[carmine palm]

on the left

this is pre-generation

unattached on left is model ref

Item Mesh is the classes Item Mesh component

Static Mesh Component*

[compact vapor]

you want to set a static mesh components static mesh before it exists?
thats essentially what that would mean.

you would need to store a component in memory with a reference but not have it actaully create fully, that would probably require 500IQ C++ brain knowledge.
you cant set a components data unless it exists.

(is this being asked becasue of a fear that components will look wrong for a split second before they actaully change to their real desired static mesh?)

[carmine palm]

You're right. I was changing it as we were talking

To expose a var to use instead, and set it on beginplay or whatever

[grave apex]

where should I put logic that should be there throughout the entire game, even when changing levels?

I know game instance is one

but can I do a player controller?

does that persist between levels?

(im doing a single player game)

[fervent breach]

hey so, for some reason, an attack I am working on doesn't work when spawned by an enemy, but works perfectly fine when I place it in the world.
it's a ball that drops to the floor and explodes. But for some reason, it doesn't move anymore when the enemy spawns it. I tried disabling all colliders, destroying the creator as soon as the projectile spawns (in case it was some how getting caught on the ball), spawned the ball outside the enemy's collider. Nothing's working

I don't really know what to show with coding, since by all accounts, nothing should be affecting the movement anymore outside of this event

[lunar sleet]

Considering I have an RTS project where I make the camera move faster when shift is pressed, it’s certainly possible

[lunar sleet]

Try using Enable Input on Begin Play, I doubt that should affect that node but worth a shot. And if not, show spawn code

[faint pasture]

4000 accel with 120k max means you'll hit max speed in 30 seconds

Probably not what you want

[proven dune]

Could someone please help me with this?

[hidden shard]

Hello.
I am wondering if there are two ways I can come up with to implement the gimmick of dying when hit by thorns.
1,cast it on the player and judge.
2,get player pawn to get the player and judge
In this case, would the second method be lighter?
Also, are there any disadvantages?

[lunar sleet]

How are you getting the reference in the first method and what the hell does Google translate mean by “judge”

[edgy ingot]

Lighter is irrelevant here tho you probably want to use interface or inheritance depending on the complexity of the game

Tldr. If u have multiple types of things that can get damaged and they dont necessary share the same base class, then use intercace.

Eg a barrel may be damageable but dont neccessrily inherit from the base enemy class.

[edgy ingot]

Not many people will be compelled to fix an entire system.

I took a glance and the code is not something i can have in my project. You r pretty much hard coding the click on button to specific task.

A better approach would be to make the purchase button ambigious. It should work with what ever data is passed, eg wether buying a bed or a wall

[proven dune]

You're right, that's why I've continued to do a little debugging, and when I print the price, it says the price is 0, so it doesnt get the price correctly, I think thats the problem

[edgy ingot]

Thats not even the problem i mentioned but if your price say 0 well then thats another one on the list to fix

Big problem that i see is you are making the click button tied to a specific task(buying the bed)

This isnt scaleable

If u want to make building system you should learn how to use array, data table/data assets

And struct

[celest crown]

Quick question: If I have a function in a parent blueprint, can I then easily call that function in its child blueprint?

[solid needle]

my widget override function doesnt detect held down key

[languid cliff]

Yes the child is already the parent class as well.
Just r-click and in the box type out the function you want to use, it should show up

[untold fossil]

Hello. How can I get a bounding box (square) that rotates with the mesh? (Not axis aligned bounding box ABB) I want to cast a box trace in the shape of the bounding box with a slight leeway (inner push) to check for construction collision in my building system. Can't seem to figure it out. 😦

Ok nvm found it. Had to store the box extent instead of reusing it every frame.

[mighty crown]

My common UI variables are disappearing every time I restart the editor. Any idea why? I was able to consistently reproduce this and have no idea why its happening. I am saving/compiling my blueprints. Is it some sort of loading order issue with the plugin?

[frosty heron]

If that's your guess, have you check the loading phase of the plugin?

[glad herald]

What is a good way to have some arcade-y hover physics?
I tried using hover components, which work, but it's gliding too much.

I watched a video about someone creating a game about hover racer (which I don't do, my game has hover vehicles but the game is not a racing game) and they said about using barycentric coordinates to get the normal, so the vehicle would be able to hover on any surface and rotate the correct way.

I tried doing that but it's not stable enough.

Does someone have an idea how to have it somewhat stable? Using a collision below the vehicle might be viable, but I don't like the feeling of it. It also looks pretty bad.

[versed sun]

a Spring Arm with lag ?

[mighty crown]

hmm Ill attempt it. I dont think I had the right verbage in my search queries Thanks

[distant hollow]

Any friction settings available?

[compact vapor]

dude theres no way, I have those same values and there is no diference

[glad herald]

I calculate the compression, the dampening and the stiffness, if that helps.

[distant hollow]

It's usually the values such as friction that would affect stability

[fervent breach]

So I'm still having the same issue from last night - where I have an enemy attack by dropping a ball that collides with the ground, but for some reason the ball doesn't want to move when it's spawned, but DOES move when I manually place the ball into the game world - from what I understand, the issue is with the FloatingPawnMovement as when I made a test object, which only had the floating pawn movement and an object with no collisions as a visual representation, it had the same behavior as the ball attack - it will drop just fine when manually placed into the world, but not move when spawned in by my enemy (who also was not affecting the test object in any way other than spawning it).

Is there some king of bug with FloatingPawnMovement? And is there some other way I can get my attack to move and collide with the ground, without using gravity (as I want complete control over how fast it moves).
*Oh and I did try ProjectileMovement, which mostly had the same results - gravity affected the ball, but when I disabled that, the attack wouldn't move anymore

**Alternatively, I could make the attack a child actor, but I don't have any idea on how to access a child actor's variables (so the attack knows it belongs to the enemy, and the enemy can respawn the attack and adjust its speed), as the attack works fine when it's a child actor of the enemy, but I need the enemy to access its variables

[surreal peak]

@fervent breach If your Ball is a Pawn, then it probably has the Setting for creating an AIController set to only when placed

It's a dropdown in the Pawn itself

And the FloatingPawnMovement might check if the Pawn is properly possessed before moving

Just an idea though

[fervent breach]

yep, that was the issue, thanks a lot this whole problem was driving me insane

[tiny wing]

Iam trying to make a puzzle: the player need to control the character when the player in pause screen. I got everything works except mouse movement (player look ). I wanted to use mouse for player look (2Dxy) and Ui control at the same time.

when i using “input mode game and ui” - I can’t control the player look

when i using “input game only”- I can’t use the ui buttons.

is there a way to do this?

[rough wing]

I want to click and drag this cube to rotate it relative to the camera. So if I drag my mouse to the right of the screen I want the object to rotate.
Adding local rotation or adding world rotation does not yield good result as the object rotates in weird directions that is not the users intention.
How can I convert the mouse delta input into a rotation relative to the player camera?

[empty marten]

Hey peeps,
What is the best way to continuously get actors that are overlapping a collision box in a BP actor? As in if an object overlaps, constantly get its location? Also which would be better for this, component hit or begin overlap?

[jaunty terrace]

Hey! UE5 retargeting animation question :

I want to retarget this magic throw animation to my third person character:

• I'm getting the "no smoothing group information" error when importing the X-bot skeletal mesh.
• Though I got the error it still added the skeletal mesh to the project.

Some solutions I've seen or tried:

• The tutorial I'm following added their Mixamo downloaded fbx files to Blender, then export them with the smoothing group information enabled to solve this.
• I've been able to retarget animations from Mixamo before but the animation wasn't applying to the character's feet.
  • I'm wondering if that's related to this error and if exporting from Blender with smoothing group information enabled will solve that too.

Is there a way to enable the smoothing group information in Mixamo settings or do I need to use Blender to apply the animations properly?

[hushed ferry]

afaik smoothing groups have nothing to do with animations

or at least it shouldnt stop feet from moving

[hushed ferry]

are you sure you named all the bones correctly

[rough wing]

This worked

[random pulsar]

I wanted to ask smth and then tealize the mistake and made it myself😄

The problem was that i placed this big chunk of code before creating the widget and adding it to viewport

now im thinking how to add the blur transition between 2 levels

here i load the level that was above so where do i need the blur transition to be,in both or in this one

[dim agate]

What's the most efficient way to disable all controller input in a character BP aside from 1 input?

[frosty heron]

You can't do it with bp with hard travel

Keeping the widget alive between level that is

[random pulsar]

so it needs to be the same widget for 2 levels or how?

[frosty heron]

You can't use bp, it's one of the limitation.

2 options to keep widget alive, both using cpp.

Use slate or keep the widget alive somehow (I used smart pointer to prevent garbage collection)

[random pulsar]

naaaah,it sounds easy and i thought i can do it in bp😞

[frosty heron]

Nah bp is for prototype only

Imo

[versed hazel]

probably swapping out the input mapping context

[random pulsar]

there must to be something ,i cant believe there is no way

[frosty heron]

Well gl finding one

I tried and I end up biting the bullet

[random pulsar]

the worst but working one

[frosty heron]

Hard travel kills widget

Hard travel == open level

[thin panther]

your only way would be to have everything as a streaming level, but that is awful, and you lose the ability to open level by name

this is a c++ thing

if you want it to actually work

[random pulsar]

hell no i still suck at blueprint c++ its definately not for me

[dim agate]

I considered this but still unsure if this is less resource-intensive than adding bools to about the half-dozen inputs I want turned off.

[carmine palm]

I promise you, C++ is easy when you get into it 😛

[frosty heron]

Not easy for me

Still struggling

[random pulsar]

WHEN YOU GET INTO IT

[versed hazel]

yeah, I don't actually know the resource cost of that system; I went through all the trouble of switching to using it in my own project, and I can't tell you if it actually improved anything lol

[random pulsar]

oh i think i found an alternative,what if i just load that level from 0 opacity to 1,but there will be visible another level from background

[frosty heron]

U r worried about the cost of removing input context? Da faq

[thin panther]

not quite that simple

your references don't stay alive

[frosty heron]

Don't know what you mean. As long you are entering new world , youe widget is gone

[thin panther]

there will be the brief pause of recreating the widget

[random pulsar]

i mean the win level,i load it with 0 opacity and then turn smooth to 1

[frosty heron]

First reason why ppl should use cpp.
1.Bp struct
2.loading screen

[thin panther]

i repeat, your only option is some level streaming hack, but then every single level in your game needs to be a sub level, which is awful.
if you want to do this, it's c++, find someone to write the c++, find someone that already wrote the c++, or give up

[random pulsar]

here

[frosty heron]

You r recreating the widget

[versed hazel]

not my concern, no

[frosty heron]

Not sure what u mean by opacity

[thin panther]

you will still have the brief pause where the widget doesn't exist

[swift kiln]

Hey. So I have this code where if player presses mouse button and has a weapon equipped, it starts firing the weapon and since it is automatic weapon, I set set timer by event. But the "Clear and Invalidate timer by handle" needs to go to "Released" pin. Any ideas on how to fix this?

[thin panther]

a flash of the loaded level

it's not a solution

[thin panther]

that's not loading a level with 0 opacity

thats a widget

[random pulsar]

im sorry for misunderstanding)

so the alternative would be to load level and when widget loads it has o opacity ,then smoothly i make a transition to 1

is it good?

[frosty heron]

I only know the 2 options I stated above

There is no way to preserve widget when hard travelling with bp

Blueprint only project is limited, this is where you need to accept the wall

Your only option for loading screen is plugin if u don't want to dive Ur self

[thin panther]

no, that's not an alternative.

[sonic arrow]

alright, so im trying to make a keycard system in vr, currently im trying to make it so when the keycard overlaps with a box it deletes both the box and the keycard, but nothings working.

I have no code for the box or the keycard right now, I deleted it to try and think of a new way to handle it

[thin panther]

I repeat again, in bp only land, your only real option is to ave each level a sublevel, that way you have a persistent level to maintain references in.

The actual solution requires C++

[frosty heron]

Figure out what don't work, what's not detected

Print string to debug

[thin panther]

Now whether you make the C++, find someone to make the C++, or find someone that already made the C++ is up to you

[sonic arrow]

nothings even going in console, straight up its just not doing anything

its a simple begin overlap function

[frosty heron]

Well then work from there. Check your collision settings and channel

Get overlap event to work first, worry about the logic later

[sonic arrow]

for better words, how can I reference the keycard in question, then delete that and the box itself when begin overlap

[frosty heron]

Print string overlapped comp

[dim agate]

It's my question and yes I am because I have very limited experience and therefore knowledge concerning what is and is not costly to do.

[frosty heron]

And print every single comps. Once your card is detected, you can cast to your card

[sonic arrow]

I think I found something, pretty sure the collision preset is block all dynamic

[frosty heron]

0 cost

[frosty heron]

Set to overlap

[sonic arrow]

set it to overlap all but I still got nothing

[frosty heron]

Check your collision box or if your card has collision

Then check the collision setting

Keep working on the checklist

[sonic arrow]

got it working

added a collision box then casted to the keycard

[frosty heron]

K so your key card don't have collision then

Shouldn't need to add an extra collision box

[sonic arrow]

no

it was a collision box on the scanner

[frosty heron]

Just create collision for your card

[sonic arrow]

the main issue was casting to the keycard

I Forgot to cast

thats it

[frosty heron]

Always print first

[sonic arrow]

it works

[frosty heron]

U can cast after u confirm that the card can be ovrrlapped

I know but u kinda ignore the troubleshoot. Oh well

[sonic arrow]

I need to get a event dispatcher in and make a door

[molten tinsel]

Hello, I have question regard Timers and Delta time.
So, in Timer by Function you can loop animation for example every 1seconds.
Is it possible to do this with delta time somehow? Or the time I insert into Timer is already reliable?

[frosty heron]

Delta time is the time elapsed between last frame and current frame

[undone sequoia]

Guys any idea how I can fake "shoot" prediction when I am using trace lines? when plane is flying fast ? I wanna make effect I need aim before enemy but line traces are fast and they always hit you.

[nova imp]

Do you mean like drawing a path where the plane/ object would be going?

[undone sequoia]

like I wanna draw circle "Shoot here" to hit target, target is moving lets say 300 km/h but i Dont need aim before it because I am using line traces for shooting and they always hit target without pre-aiming

[nova imp]

So you want to fake the travel time then?

[undone sequoia]

yea something like that like you should shoot few metres before target to hit it but with line traces you shooot right on target

because its path is fast and not bend

[versed hazel]

so currently you can point at the target directly, and no matter how fast it's moving you'll hit it because you're doing the hitscan; and you want to have the player instead shoot at the lead pip?

[undone sequoia]

yes

i need fake it somehow so I will need aim before targeet

ofc based on his speed

[spark steppe]

you need math

[versed hazel]

you could either project the target to have collision where the lead pip is, or you could offset your hitscan projection in the opposite direction of the target pip

[spark steppe]

that won't work

unless the distance/traveltime and speed of the object is always the same

[versed hazel]

are you doing this approach for optimization reasons or to simplify player input?

[undone sequoia]

yea

[random pulsar]

hey ,i want to make the effect of trace when the arrow shoots,and i cant formulate it to search in youtube

[nova imp]

What I would do is upon hitting the target, make a call with delta time * (time needed to reach target) * Current velocity to see if you would have hit the target at the speed at which it is moving

[undone sequoia]

make it little bit "real" lets say

in real life u cant shoot at target directly to hit it

when its moving

in worst case I will use not line traces

but objects collisions

but I Wanted save performance

with line traces

[versed hazel]

I was assuming that would be accounted for by the target position

[spark steppe]

collisions are your only solution

or doing a trace every tick, and calculating the travel distance at the time

[undone sequoia]

yea but it will eat performance a lot

i will think what i will do

i cant bend somehow linetraces? make them physical yea?

[spark steppe]

no

specially if you want real projectile behavior which doesn't shoot in a straight line

[undone sequoia]

ah thank u guys for tips

I will think about it over night

[spark steppe]

that's why projectiles exist in the first place

if something like this exists in the engine it's very very unlikely that you come up with a better solution

[random pulsar]

Speaking of projectiles how can i make a trace effect for an arrow in 2d,cuz the one that i have it weird,has bugs

[spark steppe]

like a preview of how the arrow will fly?

[random pulsar]

no,the actual fly

[spark steppe]

can't you just stick a niagara system or smth to your arrow projectile?

i haven't used projectiles, so idk

[random pulsar]

yes i did like a component,but it draws the line strange

[jolly hemlock]

I have been making and re-making Character Controllers for the last week, following more than half a dozen tutorials, and each one results in different, but still broken, functionality. These are extremely simple, involving the third person controller and 3 inputs (move, camera, jump).
In my most recent attempt I ended up with this error on my character controller BP that claims that the BP is not a controller. Is this a common experience for others? Repeating the same steps and getting different results each time?

[random pulsar]

it becomes thinner and thinner and when you shot backwords it becomes really weird

so i thought about making another trace but seems like i cant find the right searching request

can yall help me to formulate the request?😂

[versed hazel]

you can't bend the line trace unless you do multiple line traces, which will make it more expensive. However, you can adjust your target offset based on distance and velocity to account for things like bullet drop, and then do your single line trace there. Note that it won't be physically accurate, so there may be cases where something should block your shot but doesn't because you aren't actually tracing the true trajectory of the projectile, so it's up to you if this results in something accurate enough for your purpose

[versed hazel]

it looks your BP_OddPlayer is your character blueprint, not the controller. Here I'm using the ThirdPersonCharacter blueprint for all my logic, but the player controller is PlayerController

I don't know why I made the screenshot so wide 😅

[dreamy wadi]

Hey, I'm using Ascent Combat Framework and I'm unable to get my UE4 skeleton to work with retargeting. I've used both the assign skeleton option and also created a child of the ACF skeleton to replace with my UE4 mesh and rig. Does anyone know how to fix this?

for reference, the bones are set up correctly when connecting my custom child BP

[versed hazel]

I'm allergic to skeletons, but this might be a better question for the animation channel

[dreamy wadi]

will send one there

[spark steppe]

there's a predict projectile path node or smth which takes bullet drop etc. into account afaik

which could be used to determine the target location, still the target could have moved at the time the bullet arrives

[versed hazel]

I haven't tried using that before, it sounds saucy

[spark steppe]

https://docs.unrealengine.com/5.3/en-US/BlueprintAPI/Game/PredictProjectilePathByObjectTyp-/

this afaik

[faint pasture]

Trace every frame over time

[versed hazel]

I wonder how many positions it returns

[faint pasture]

it's great

[versed hazel]

is there a way to add a blueprint node via hotkey? I don't like having to go back to my mouse every time lol

[jolly hemlock]

Thanks for your reply! I had just named it "OddPlayer", but it is a BP from the Character Controller class. I just remade it from scratch again, and it worked fine, as it did the more than 10 times I had previously. It is truly confusing me as it's so simple there isn't much to screw up. Bug? 😩
Thank you again for taking a look though!

[fleet lichen]

Hello, I'm new to Unreal and I'm reading other people's work. One of them uses this node, and I'm not sure where he got it.

[copper tree]

Seems to be a function that the person wrote inside that BP Sky Sys Pick Sun actor, not a default UE node

[fleet lichen]

oooh

thank you

And this one from target to Light component?

[remote meteor]

tick wrap axis on the horizontal axis in the blendspace settings

[dark drum]

You've placed the node inside a character which isn't a controller. You would need to get the controller of the pawn/character and connect to the target.

If you placed the same node inside a controller, it can use self as a target.

[grave apex]

Im using a playerController in order to have logic that persists across multiple levels, but beginPlay gets called whenever a new level is loaded, I only want it to be called once for the entirety of the game. How do I do that?

I know gameInstance persists across the whole game, but I dont know how to run something on the game starting using a gameInstance?

[trim matrix]

Anyone able to help here. I'm trying to have this actor move along the spline

I'm using an interp for now but it doesn't seem to be working and I believe I've got it setup right

[versed hazel]

that is just to access the light component on the directional light actor

[fleet lichen]

oooh

[digital palm]

what's the equivalent of SanitizeFloat in blueprint?

[crystal crown]

Why does enable/disable input have a delay?
it's kinda unusable like this

[trim matrix]

so manage to find the issue I have is due to the spline length being super long over 1.0 is nothing in comparison and actually end of the spline is line over 5000

[faint pasture]

what delay does it have?

[versed hazel]

if you need to access the spline by percentage, you can use duration - by default the duration is set to 1, and then you get location at Time Along Spline

[crystal crown]

actually nvm. it's not really a delay but i wish the transition was smoother if i hold down the key the whole time

[versed hazel]

otherwise you can get the distance of the spline use that to scale your distance-getting

[trim matrix]

so duration would be 0 - 1 ?

[versed hazel]

unless you've changed it, yes

[trim matrix]

don't believe I have

is there a way I can limit the interp speed so that the actor kind of tops out at a speed ?

[faint pasture]

yes

[trim matrix]

at the moment the interp obvs is shooting actor around the spline which look unrealistc

[trim matrix]

I know there is a const version of it but that also won't help in this case

[faint pasture]

const can be what you want, do you want it to move at a constant speed or reach the point in constant time?

[trim matrix]

let me show you example

As you'll see because player is closer to the other side of the spline it'll shoot round spline to get there which is right. I just don't like the shooting it's doing if that makes sense

[faint pasture]

Use FInterpToConstant and dial in your speed

[trim matrix]

I would prefer to have it still do what it's doing but not kind of going that fast

arr okay

anyway I can like merge them together

so get the build up to speed and the slow down to speed but still clamp as it was the movement so it's like the constant one ?

[versed hazel]

like an FInterp Ease in Out?

[faint pasture]

Yeah you'll have to do your own interpolation, can't use one of the finterptos

FInterpTo is more for "chasing" a value

I would FInterpToConstant the 0-1 range then run that through an FInterpEaseInOut

to turn a straight line into an S shape

[trim matrix]

yeah

I know it can defo be done in C++ but I've come to realise do it in BP and if it's heavy on performance move it to C++

[trim matrix]

so I did look at the Ease in and out but it didn't look right to me like how I include it

Cause theres these two

never used them before though so

[versed hazel]

yeah, use the one you like better. The A is your start position, B is your target position, and Alpha is the percent between them (0=A, 1=B, 0.5=halfway between the two)

you can select ease in out from the Ease function list, which I am pretty sure does the exact same thing anyway

sorry, not position, these are floats

[mental bobcat]

Hi, I have 2 variables I'm using of the same struct to store my (local) player stats. The functions I wrote previously that increased their exp, level, etc don't seem to be working. Is it not possible to pass references of the struct?

[faint pasture]

Assuming everything you're dealing with is in the 0-1 range, then A is 0, B is 1, Alpha is the output of your FInterpToConstant

[faint pasture]

Ignoreing the fact that player stats should probably be on PlayerState and not gamemode.
You're passing in a copy in that function call, so nothing will permanently update. I'm pretty sure anyway

[mental bobcat]

I don't think it matters where they go so much in a local only game. The copy thing makes sense I guess, I guess I'll just make 2 different structs, 1 for each player.

[trim matrix]

well the spline length obvs isn't 0 - 1 but i'm using mapped range float for that so 1.0 equals length of spline

[faint pasture]

Do you want it to always take the same amount of TIME to move from place to place, or move at a consistent speed?

[trim matrix]

most likely yeah

[faint pasture]

Like if the spline is twice as big, move twice as fast or take twice as long to do it?

[trim matrix]

same speed

[faint pasture]

so take twice as long?

[trim matrix]

regardless of length of spline

oh wait sorry hang on

so affectivly i want it to take 30 seconds

[faint pasture]

ok

[trim matrix]

whether spline is length 10 or 1000

[faint pasture]

So you'd do it like this:
Timeline taking 30s to go from 0-1 -> FInterpEaseInOut to make it S shaped -> map range from 0-1 to 0-SplineLength -> set position

You can also just bake the s shape into the timeline, however you wanna do it

then you could lose the FInterpEaseInOut

[trim matrix]

I can't get out of using Timeline can i ?

like you said I'd have to make my own kind of interp rather then using just simply one of their functions

[wise widget]

hey, is there a way to get vertex positions of a skinned mesh in blueprint? (it can be the skin pose)

[faint pasture]

You can but you'd basically be reinventing timeline

You want a thing to go from A to B over X seconds

that's exactly a timeline

[trim matrix]

yeah at this early stage I'd rather not be reinventing haha

[quartz ferry]

Is it not possible to alter the loop time of an Event by Timer while it runs?

It just uses the initial "Running Shoot Delay" value, reguardless of how it changes

[jolly cipher]

Not sure if anyone could give me some advice

I bought the Ultimate Multiplayer FPS Framework
Was thinking to merge this with ACF Framework, at least to to replace the shooting system,
I hit a road block with the anim BPs.

The FPS Framework has an animBP that has a custom anim instance class as parent,
ACF has a similar setup, it uses a custom Anim instance class as parent,

Was thinking to try and convert it to a layer and use the link anim graph but I would need to rework alot of the logic as the layer would trigger differently, this would throw some of the IK mecanics and upper body and lower body to not react the same way,
My knowledge on anim bp stops at state machines unfortunately lol
Not seeing any wayt to merge these via blueprints either so,

Tried my hand at C++ and try to inherent from ACF's Anim Instance class,
Got it to compile but just crashes once I try to re-parent in unreal, trying to debug this but not going well lol

Might be looking for a plan C, would anyone have any tips or any ideas on how to approach this differently?

Actually would it be possible to dynamically swap Anim BP's during run time?
For example if I equip a ranged weapon, only then do I need to swap anim bps,
Is that something standard to do?

[faint pasture]

Merging 2 plugins sounds like an absolute nightmare

[faint pasture]

do it by the timer handle

blue thingy

[jolly cipher]

It is, but found the Set Anim Instance Class that I can trigger at run time.
Basically I force a different anim bp with I equip my gun,
Dont know if this might cause some performance issue in the long run but I can easily swtich between these 2 animBP without having force merge these 2 plugins.

[scarlet flare]

someone pls explain what is wrong, i am new

[faint pasture]

Input isn't enabled on the door

your E event never fires

[trim matrix]

Your door actor BP does not consume keyboard inputs. Keyboard inputs would generaly go on the player character.

[quartz ferry]

how so? What node should I pull from the handle to set a new time?

[faint pasture]

Just drag off it and poke around

[scarlet flare]

Thank you

[faint pasture]

look for anything timelike

[scarlet flare]

Thank you

[faint pasture]

You don't necessarily want to enable input on the door tho

Instead, use E in the character, and have it figure out what to talk to, and what to tell them

For your first draft of this, you can get overlapping actors, foreach on them, cast to Door, and if it's a door, call OpenDoor on it (add that event to the Door)

Later you'll want an interface or component for general interaction but do this first

[scarlet flare]

okay

[gritty aspen]

hello
when i add this settings to the horror engine player head shake this happen i want a solution

[quartz ferry]

I'm reading through all the results and nothing seems relevant, but idk if I just dont know what to look for
Ive checked with "set" and "change" as the first word in the search too, but nothing like "set time" or "set delay" shows up

Wait, it seems "set timer" just makes a new one with the new time variable

I'll check if that works

oof, nevermind. Set Timer isnt available in blueprint

[jaunty terrace]

Thanks for replying! When I import a character from Mixamo it doesn't have a root bone so it doesn't have the same bone structure as the UE5 character I'm targeting.

Would I need to use Blender to add a root bone? That's one of the solutions I've been seeing but wasn't sure if there was another way.

@quartz ferry I love your username 😂

[edgy eagle]

what if in for each loop i'm deleting the element of array?
can i decrease the index to be sure that all elements are iterated?

[quartz ferry]

lol thanks

[gritty aspen]

when i add this to another player it works but in the horror engine no

[swift kiln]

Does anyone have any idea on how to spawn certain amount of actors when there are more spawn points than actors themselves?

[trim matrix]

#animation message

[faint pasture]

reverse for loop

[trim matrix]

Anyone able to help with the one I tagged above at all ?

It's when I'm trying to have a bone on my skeletal mesh look at the player it seems off

I don't know why though it's off slightly write wierd

[faint pasture]

Draw a debug coordinate system at the bones location and rotation to make sure it's not a vertex weighting issue

or otherwise make the bone itself visible

[trim matrix]

So I have debug showing and I can see where the bone is and where it looking at

Bone itself tbf looks off slightly

[faint pasture]

I'd start by ruling out any clamping etc

[trim matrix]

So tried that still was the same

All I can think is animation is the cause but I didn't think that affected stuff tbf

[faint pasture]

Try reset the axis stuff to default

[trim matrix]

I'm gonna try going through that tommorow

It's right wierd issue

[faint pasture]

The fact that you have local space turned off for the look axis seems a bit sus

but idk enough to know for sure

[glass fern]

Should I create a blueprint instance for a weapon each time I equip a weapon?

Or is there a more efficient way

[faint pasture]

There is

Just have them around and swap them out

or don't, depends on your setup

what IS a weapon, is every weapon a BP actor class?

[glass fern]

Yeah I was thinking each weapon would inherit from a base BP_Weapon that is a BP actor class. Altering their static meshes and colliders

[faint pasture]

What happens to an equipped/owned weapon that you are not currently holding?

I switch from my rifle to shotgun, what happens to my rifle? Do I put it on my back, does it just disappear, what

[glass fern]

Becomes an item holding reference to the weapon blueprint

Disappears

[faint pasture]

to an instance or a class?

[glass fern]

Item would be an object not an acotr

actor*

[faint pasture]

Does it hold a reference to the weapon class or an instance?

[glass fern]

The class at the beginning, maybe it could hold ref to the instance as long as it's picked up and owned by a player?

[faint pasture]

I'd probably start by spawning/despawning them for now and later think about just hiding them but not despawning

[glass fern]

Is this an ok approach anyway or is there a better approach for handling weapons?

[faint pasture]

I mean there's a million approaches

how different are the weapons?

[glass fern]

Medieval like for example

Swords, spears etc.

[faint pasture]

I mean how different are the classes?

[glass fern]

Oh, right now they have different static meshes and colliders

[faint pasture]

If they're data only then a "weapon" can just be a structure.
SM_Spear
Damage = 20
DamageType = Thrust

Swapping a weapon could just be telling your weapon actor "here's your new mesh and data and animations etc"

depends tho

[glass fern]

How would I set up colliders? Variable too?

[faint pasture]

However you wanted, even just bake it into the mesh idk

Don't worry about that until you need it tho

Just hiding a weapon actor can work just fine

This for a dark souls like thing where you have 2 weapon sets?

[glass fern]

I don't have a robust design yet, just practicing. Was thinking to have any amount of weapon sets like daggers, spears, swords etc.

[jade skiff]

I have a UI that's supposed to default to a value of 100 for player and opponent, and increment by 6 every five seconds. It also updates whenever you spend money. This update pulls the player's cash value from their player state. The problems:

1. When you spend, it doesn't update your cash value on the opponent's screen until the 5 second update
2. Player 1 (Server)'s Opponent value lags behind one tick. It starts at 100, goes to 0, then up to 106 and increases as expected.
3. On Client, own cash sometimes visually misses an increment tick, although the cash is spendable.

[faint pasture]

replicated variables with RepNotify my dude

Delete every multicast from your project

re-add them when you know which ones you need and which you don't

https://docs.unrealengine.com/4.27/en-US/Resources/ContentExamples/Networking/1_4/

[mental trellis]

Damn.

You can send a command that sets everyone's cash?

Can you say hacking is great?

[faint pasture]

You can't?

How do you think I got so rich

[mental trellis]

😄

Well, sets the cash fro that one person for everyone. 😦

This node is bad.

Do not use it.

[faint pasture]

MyWellsFargo.SetCash(INT_MAX)

[faint pasture]

Remake your system with nothing but replicated variables, onreps, and run on server events. You'll get it.

[gritty aspen]

.

[glass fern]

Why? It's everywhere in my blueprints.

[mental trellis]

Then your blueprints are bad.

It's a convenient hack that will break down on edge cases and there are very easy alternatives.

[faint pasture]

Becuase it literally means "Get the first PlayerController" when you usually want "Get this pawn's playercontroller"

You usually have a more explicit way to get the pawn/playercontroller/playerstate you actually want to get.

[jade skiff]

Okay, will do. What would you recommend to prevent cheating the players money?

[glass fern]

It works if the game is not multiplayer right?

[faint pasture]

A player's money should be a replicated variable in their playerstate or pawn.

[mental trellis]

That doesn't mean it's good practice.

[glass fern]

Even if it's cached somewhere on BeginPlay?

[faint pasture]

Give an actual example of where you use it.

[mental trellis]

I'm not sure why you'd cache that value.

[jade skiff]

Okay, I was having it in both player and playerstate but I guess that's overkill. While I have you guys, does this look like how you would update the UI widgets?

[faint pasture]

use repnotify

read what i linked

[mental trellis]

This is the better version of that player controller index 0 thing. (except this one is for the pawn, but you get the idea)

[trim matrix]

Yeah thats cause of an issue i was having with something else I think

I'm thinking animation might have something to do with it

[faint pasture]

Here's how I'd do it.
PlayerState:
OnRep_Cash -> trigger dispatcher OnCashUpdated

Widget:
Construct -> get chain to get to the PlayerState it cares about -> Bind some event to OnCashupdated

Now Widget knows whenever Cash changes

You can also do it the other way around where a widget is just told what playerstate it cares about when it's spawned. Either way

And the widget can just have a value binding (it'll check every frame) instead of waiting on an event, you'd do that for something that changes all the damn time like your cookie count in cookie clicker or your HP for a health bar

[trim matrix]

Reason I say is cause I'm running a idea animation so I'm thinking maybe offset in animation is causing issue

[faint pasture]

Before or after the look at?

[jade skiff]

Okay, I'll try that design. Thank you for the feedback.

[trim matrix]

So animation is running in machine so before

Look at is happening after

But I'm not like reseting bone or anything so I'm thinking it's taking bone and adding onto it the look at rather then look at overriding the bone

[faint pasture]

I'd lose all clamping and make sure you're rotating the right bone

not the one before it or after it

test with a mesh with just 1 bone

and also test with base pose

[trim matrix]

So I think my issue is I don't have a base pose

[faint pasture]

every skeleton has a base pose

[trim matrix]

Like it's taking the state machine in

[faint pasture]

try just disconnect it

feed nothing in

[trim matrix]

Thats my plan tommorow

I'm thinking something is going odd there

[faint pasture]

my money is on some settings for the look at or maybe it's doing some blending or you have a post process or something

or you just got the wrong bone

[trim matrix]

I'm banking on blending issue

[trim matrix]

Defo not wrong bone I defo checked that earlier

Also look at is annoying causing you can't control fully how it does the look at

Might have to look at control rig but will see

[digital palm]

isn't it supposed to display 0.2? currently it's displaying the class default value, any idea?

[faint pasture]

Is it actually creating the save game file on your computer?

[digital palm]

yup

[faint pasture]

Show how you're calling these in sequence

[spice sequoia]

I have a weird issue with a BP with a FieldSystemComponent - If I Place the BP actor in the level before play it works fine, however if I spawn the actor at runtime I get a lot of errors saying 'Accessed None trying to read FieldSystemComponent' - with the exact same BP setup - the images are the first node in the construction script where the error shows on a spawned (not found) / Begin play (found) versions of the same BP - Not sure how to resolve this?

[faint pasture]

Try move code to begin play

[digital palm]

I'm in the game instance here. Just to make a test, I plugged the create save on begin play once. Then I plugged the load game after

[faint pasture]

Show property settings for Volume Master

[spice sequoia]

Thanks, I just tried that - copied the construction code to Begin Play - still the same result (unknown) - almost as though the field system component is not initiated fast enough to be found?

[digital palm]

before it was private with a getter/setter, but same result

[edgy eagle]

any reason why EnchancedInputAction don't trigger when paused even when Trigger when Paused checkbox is set to true?

[jaunty terrace]

@hushed ferry Nvm I got it working, last time I tried was months ago so I can't remember where I mixed things up but the feet are working too

[ocean gate]

hello! does anyone know why my actor instantly snaps to the trace hit location instead of lerping to it smoothly like I expected it to?

[versed hazel]

the alpha isn't being changed over time. I was confused by it at first too, don't worry

if the alpha = 0, the output = A; if the alpha = 1, the output = B

[faint pasture]

You are literally telling it to go 99.9% of the way there.

You need to save that location then kick off a timeline or some other thing that ticks that can set the location over time

[ocean gate]

aaah that was it! thank you.

[digital palm]

The variable was corrupted in a way, I had to remove it and create a new one

[compact vapor]

Here is my character, Just a floating camera.

How can I rotate the camera?
Adding rotation to the spring arm works perfect. But it doesnt move the whole cahracter, so it gets offest from the cahracters true front/back/left/right.

for example: (rotating the spring arm 90 degrees to the right makes the W key move the camera to the left (because rotation is offset from direction)

any way to counter-act this?

Is it possible to just rotate the capsule its self?

[faint pasture]

Have character ALSO use the control rotation

Have spring arm, camera, and character movement component use control rotation

then just change control rotation with your inputs

of course character only wants yaw typically

just look at the template 1st person project

You don't need spring arm for 1st person only but might as well keep it for a 3rd person option if that's a thing

or if you want the lag mechanics

[compact vapor]

what gets the control roation, the spring arm?
because my BP at the highest level (above root) is set to yaw already

[faint pasture]

Anything that wants it

That's the poitn of it

it's a rotation that represents your view rotation

and other things can use it for stuff

[compact vapor]

enabling control rotation forces my components to have a locked roation that doesnt move (cant angle the camera slightly down)

[faint pasture]

are they using control rotation too?

just load up the 1st person template and look at it

[compact vapor]

by control rotation do you mean this? because my spring arm has one of these bools

when I enable this, my spring arm cant rotate

[faint pasture]

What are your mouse inputs changing

[compact vapor]

its the E and Q key for roataing

(this is for an rts game)

[faint pasture]

ok what do those keys do?

if it's not add controller yaw then change that

[compact vapor]

original rotation node in comment didnt work so i tried the node below and that works but has the roation offest problem

[faint pasture]

Input -> modifies control rotation
...elsewhere....
Whatever wants to, uses control rotation

[faint pasture]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Pawn/Input/AddControllerYawInput/

[compact vapor]

thanks man

been a head ache going back and fourth between deciding wether or not the player camera BP should be a pawn or character.

literally have transitioned back and fourth like 8 times.
seems like I might be sticking with character from now on 🙂

you a fan of halo? and / or RTS?

[lunar sleet]

Sry, I said add movement input, I forgot it was one of those since you’re rotating the controller

[faint pasture]

Pawn if it's an RTS

It's an eye in the sky right?

Like normal RTS?

You could do that without a pawn at all, but the simplest version would be just a pawn that moves around on tick

[compact vapor]

I disagree, too hard to implement functional camera movement for maps with large elvation differences

[faint pasture]

Just trace down or sample or otherwise cook up a z value for the land height

How would a character help? Do you just have a gigantic capsule sliding around?

[true valve]

WHat's similar to RandomPointInBoundingBox but arbitrary points? I want to specific amount and space them out in area.

[faint pasture]

What's the area shape?

That's not trivial

[true valve]

Let's say I use a line trace then spawn a Sphere Trace on the impact point or i use a sphere trace. And use that area.

[faint pasture]

A sphere trace won't get you a surface

what is the actual shape you want to generate random positions inside of?

[digital valve]

Anyone know why this would work for equip but not dequip?

[vestal plinth]

is there a way to edit a data asset via blueprint, or does it need to be done in C++?

nevermind, worked it out 🙂

[edgy ingot]

Well now u r leaving ppl hanging/questioning by just saying worked it out

The answer is you can do it via bp for those wondering

[vestal plinth]

Now I have an air of mystery

[lunar sleet]

At runtime? I thought they were read only

[carmine palm]

Same. Thought that was point of them lol

[spice viper]

Need a little more context, and view into the what the rest of your BP is doing. If I had to wager a guess is your equip has a "client" in it, but remove does not suggesting remove is server only?

[edgy ingot]

At run time in editor time

Is possible i think

I can also change data table in editor play time

Not that we should 😂

I was just doing someones request

I changed da asset with editor utility widget, judt by getting a ref to the da so im certain its possible in editor runtime.

Im not sure about packaged tho

[ocean raptor]

How do I create one of these types of events? I've looked everywhere I could think of.

[edgy ingot]

Read rpc in #multiplayer

[spring osprey]

hello all. I'm new to soft references in UE and wondering how to best optimize memory consumption. So if an asset is loaded into memory in a level, and then the a new level is loaded that doesn't need any of the assets from the first level, do the assets need to be manually removed from memory? i.e. Will the assets be unloaded if the object that initiated the loading is itself unloaded or will they stay in memory even after the original level is unloaded?

I couldn't find the answer to this online so thanks in advance if somebody can explain how this works

[frosty heron]

It will be automatically removed from memory if you do hard travel in packaged game.

That's not the case in editor time. What's loaded remain loaded

How do I know this? You can check your self by opening console and type

Obj list class=(the class you r checking)

It's in the video by epic titled demystifying soft object ref

[topaz gazelle]

What's a good way to share information between different classes? Like if I wanted to store what team an actor belongs to, this property could belong to characters, pawns, actors. I tried reparenting to a base class but I didn't realize this would change the child class to the reparented class.

[dawn notch]

Actor components. Make a team component, put one on any actor that can be on a team.

[frosty heron]

Depending on the data. Something like team should go to game state

[topaz gazelle]

Thanks

[distant hollow]

I have an array of Tags.

EG:
Ind 0 - "BuilderTools"
Ind 1 - "DrawnWall"
Ind 3 - "FPID_857"

The number following behind "FPID_" can be any numbers between 1-1000 (unknown).

How do I search through the array to retrieve the full "FPID" Tag?

[lunar sleet]

If they’re gameplay tags, there’s get tag name

[distant hollow]

I'm using normal Tags

[mental trellis]

If you weld the bodies, they shouldn't collide with each other?

[ocean raptor]

Thanks for the pointer!

[thick prairie]

Hey guys. I have an issue. I want to create multiple different dataTables using the same structure and use them in a actor component. My issue is, that if i make the dataTable a variable and plug it into 'Get Data Table Row' node (1), all my outputs disappear (2). Is there a way arround it?
What I'm trying to do in general, is to make dataTable with actor stats per level, each row is a new lvl so at lvl 1 it has 100HP at lvl2 200hp and so on. I want to have same dataTable but with different values for different actor, so Unit1 is using DataTable_01 and Unit2 is using DataTable_02, both have the same structure, but different values per level. I take loading that into main actor wouldn't be that hard, but i want to have actorComponent that loads those DataTables and assing health and level values from it. I don't know how to change those DataTables on the fly in a actorComponent without breaking all the links ..

[digital palm]

About localization, is there a built in way to convert English to en? (for set culture)

[surreal peak]

Pretty sure it would be the other way round

You can ask UE for all the localizations and it should have a way to get "English" from that

Or all the cultures to be more precise

[surreal peak]

Shouldn't you get a Wildcard pin when you use a Variable?

[kind estuary]

When making an rts do you still use pawns and possess?
Since you control more units at once doesnt it make sense to use just actors?

[frosty heron]

You can have pawn without possessing it

Though cmc would be too heavy for an rts game or any game with lots of actor

[kind estuary]

yeah

so instead just use something simple to move the actors

but the cmc is automatically replicated

i never worked with multiplayer, but i assume the cmc is set up for that

[frosty heron]

RTS is one of the hardest genre and UE is not really made for RTS, it's made for competitive shooting game.

That's not to say u can't use UE for RTS but you will need to make your own

RTS with multiplayer 👀 if you are not a programming vet , consider doing something else

[kind estuary]

well this one is 2d and its more like tactical

though maybe real time

so if i make them actors, and move them with lerp

how do i replicate that

[frosty heron]

If u have to ask that then I recommend doing a simple mp first

Instead of rts

Cmc is thousands lines long

Some ppl tries to make their own movement component

Took years

Might as well just buy one from market place. General movement component. It cost 350 usd or more but cheap considering the ammount of work that's put in

[kind estuary]

i think it can be simplified

for example aoe2 replicates only the command to move

so when you select a unit and move it somewhere

it sends a packet

and then the other players replicated that just one time

[frosty heron]

I still think it's bat shit crazy for a solo dev to make a rts game like aoe2 with unreal engine but up to you

Have no comment since I never attempted anything like RTS. Cmc for mp alone already gave me headache

[kind estuary]

cmc wont work because as you said performance

[frosty heron]

Yeah u will have to write your own move logic in cpp which prob take very very long time even if you have the skillset for it, that's my opinion

Multiplayer is not really bp territory either, unless u making simple card game then thats achievable in bp

[kind estuary]

im just making a small practice test nothing very serious

so like some cubes going against each other

that wont be hard i think

[frosty heron]

That's not simple, especially in mp but u do u

[kind estuary]

ok. thanks for warning. ive done some games, but mp is completely new to me

[keen widget]

quick question: what is a difference between them ?

[frosty heron]

One is a pure function the other is not.

The one on the right also takes a string by reference

If u hook a string variable the changes will reflect on the string that you pass

[keen widget]

oh, now i see that second one will return also Index where changes was made, thanks

[frosty heron]

The index is prob useless the important part is u are passing by ref

So if u feed that with a variable that variable will get updated

[thick prairie]

I don't know what that is. I'll google it 🙂

[surreal peak]

It's the white/grayish pin that doesn't have an actual type assigned yet

You can usually drag that out and simply break "Break" followed by the Struct Class

[thick prairie]

I mean, I've seen it at some point, but don't know how to work with it 🙂

ow now i know what You mean. The out pin has no option to break it since the datatable is unspecified (i think that's what You call it)

[surreal peak]

Please read more carefully (:

I wrote you should drag from the pin out

As if you'd call a function on it or similar

[thick prairie]

Oh, You're right, sorry. I got some results. Thank You 🙂

[river schooner]

Is there a reason why in the screenshot with the save fonction, the value printed is none but in the other one, it prints what it should? seens like something is wrong...

it prints at the same time or after adding the value to the arraw

[river schooner]

this error is so dumb, someone help pls<

[lyric quiver]

I'm trying to add footstep sounds to a walk animation for the third person character. I have notify tracks set up and I can hear the footsteps in the preview but not in the game.

[dry sleet]

Well, no clue what your Save Actor function is doing or what's outside the cropped image in the first one, but in the second image you're ensuring the array you're getting from is not empty.

If you're getting "none" in the first one, are you sure there's any elements in the array to begin with?

[river schooner]

there's at least one

[river schooner]

that's the save actor fonction

it basically set a value into the arraw and this arraw should save and then I should be able to reuse it when I play again but it seems that I DONT KNOW WHY but the arraw is empty every time when I rejoin..

@weary bay

[spark steppe]

you can't save object references

now gimme my $10

[weary bay]

Please don't mention money rewards for solving issues. If you want to pay people to work for you look at #instructions .
In a similar vain please don't just @ someone. It is not polite.
See rules 2 and 7

[river schooner]

???

[river schooner]

I want someone to help me, sorry man

I will wait

[spark steppe]

actor instances don't save, you have to reinstance/spawn them yourself

and save what is necessary for that

[river schooner]

when it spawn this arrawy is empty..

[spark steppe]

yes, because they don't serialize in the default unreal save game system

[weary bay]

Seems Ben is helpful enough. 👋

[river schooner]

what does that mean?

[trim matrix]

@faint pasture so manage to sort it

[spark steppe]

that you should read the docs

[river schooner]

because for all the other values, it was working fine

[trim matrix]

made a static animation and blended it with the animation running and re-turned on local space and it all is working now, it's looking correctly at target

[spark steppe]

because they are primitive data types

[river schooner]

primitive?

[spark steppe]

yes

[trim matrix]

So if I have something on a spline. There isn't any way of getting it's speed is there ?

[river schooner]

how do I make it primitive too then?

[spark steppe]

#blueprint message

[river schooner]

i am spawning that at the begining of the game

everytime the player join

[spark steppe]

i don't see how speed is related to spline?! you can get an objects velocity to calculate it's speed like usual

[trim matrix]

but you can't get their velocity when your setting their location on tick

so I need to manually caluclate it

i think I can get there location and then delay compare

[weary bay]

Current frame position - Previous frame position/ DeltaTime = velocity

[trim matrix]

and - one from other

[spark steppe]

then you already have speed somewhere?! since you need to know where to place them on tick

[trim matrix]

bassically this haha

[trim matrix]

nope cause it's not moving with physics or anything

[spark steppe]

still, you have to do some math to decide where to place it on the spline?!

which contains the speed

[trim matrix]

does it ?

I've never seen this so be good to know where this is

[spark steppe]

well, how do you decide where to place it on tick?

[weary bay]

Oh yeah Ben is right :P

[trim matrix]

with a set actor location

and an interp constant going into the location

[spark steppe]

thats how you set it, not how you decide where to set it

[weary bay]

Before placing you already have to have some speed parameter to use to determine what position of the spline to use

[spark steppe]

the interp const interpolates over the spline length i guess

[trim matrix]

so thats the interp constant speed

[weary bay]

Someting like: GetGameTime * MySpeedVariable = CurrentDistanceAlongSpline
Which you then use to sample the spline.

[trim matrix]

actually no I tell a lie

I set it based on a float

[river schooner]

what is a spline duh?

[weary bay]

How do you set CurrentSplinePos?

[trim matrix]

I'm doing my interp here

[weary bay]

Ah fair enough

Yeah then you can just do
Current frame position - Previous frame position/ DeltaTime = velocity

Like, you could calculate your velocity from that interp, but fuck it.
It's easier to just calc it afterwards.

[trim matrix]

well I was thinking that in terms of surly some how it can be done with spline

but like you've put in past I've done the location frame thing

[weary bay]

Normally I'd hard calc the position on the spline from a Velocity variable, so you already know it. But here you are offloading some interping to that interp function. So it's annoying to get an expectation of the velocity.

[spark steppe]

since this is constant interpolation, it might be just the interpolation speed / distance?! idk i'm one of the persons who would have to sit down 5 minutes to write a correct formula 😄

i'm just sure that this is a simple math problem :>

[river schooner]

reinstance definition?

[spark steppe]

or just the interp speed 🤷

[spark steppe]

did you just make up a new word?

[river schooner]

... bruh reinstance

[spark steppe]

https://www.merriam-webster.com/dictionary/reinstate

since you spawn those actors when a player joins, you would need to associate your saved data with the already spawned ones

[river schooner]

that is loading it

[spark steppe]

since i'm never going to see the $10... invest them in a save system which allows for object serialization

[river schooner]

when I am doing the ''is valid'', its never valid cuz the arraw is none

[trim matrix]

What I done wrong here I'm pretty sure I done it right

Current frame position - Previous frame position/ DeltaTime = velocity

[spark steppe]

because objects DONT serialize to save games

[river schooner]

its not an object its a reference to an object

[spark steppe]

an object which doesn't exist anymore when you load the save game

[river schooner]

it is

it spawns

[spark steppe]

not the childs

you would have to do the same for your ChildArray

[terse moss]

Anybody know of a good way to smooth out spring arm length changes when the arm collides with stuff? I can enable lag and lower the speed and it works, but obviously it impacts all camera movement and not just the spring arm length change

[trim matrix]

so this is something strange my get actor location for some reason seems to thinking the actor never moves and is stationary

[spark steppe]

do it like you do with your building, where you store the class and all the data that's necessary

[spark steppe]

where do you store last location?

[river schooner]

wdym?

[trim matrix]

in a variable before it delays until next tick

oh wait

[spark steppe]

you have to store it before you set it's new location ofc

or after setting the new location, but before calculating the speed

[trim matrix]

I think this is where I use a then function I think

cause at moment it obvs is setting it then checking it against current which will be same cause it's all done on same tick

[spark steppe]

here, in color

[trim matrix]

nope it still thinks it's not moving

[river schooner]

mh

[trim matrix]

Sorted

this is what I had to do in end

[spark steppe]

no

this is bad

set last location after you calculated the speed

and remove the delay

[river schooner]

like that?

[solid needle]

hello, making a random place name generation thing, when using random array item and taking the int from the index, it provides 2 different results when printed

[spark steppe]

you still have objects (references) in your save data... you can NOT do that, last time i'm telling you this

[solid needle]

does the random node regenerate the index each time?

[river schooner]

i just dont understand man

[spark steppe]

because every time you use the output of the random item it gets called again, as it's a pure node, this node bugs me too, you can either use it's index output or the other result... (one way would be to store the index and use a get node on the array to get the actual element)

[solid needle]

ah shit

[weary bay]

If you are uncertain you could always store it in a (local) variable. This ensures you know it never changes.

[solid needle]

did

didnt work

[weary bay]

But are you using that int variable everywhere? Where do those other lines go?

[terse moss]

Well if anybody knows anything regarding smoothed out spring arm collision length changes in BP, just @ me. Thanks.

[solid needle]

prints

for bug testing

[spark steppe]

2 lines = 2 get random element calls with different results

[weary bay]

Could also print the variable everywhere to ensure you're printing the correct thing

[solid needle]

does the inclusion of print destroy it then?

[spark steppe]

you should use the "Random Int" variable as index of your get node (and the print of the index), then it should be fine

[solid needle]

like so?

[trim matrix]

how come

[spark steppe]

you can use the index from an "random array element" node, but just connect the index output to store it in a variable, then use the variable

[solid needle]

i did

[trim matrix]

I'm genuinely asking as it works both ways so I would just take it it's working fine

[solid needle]

here

i need both numbers to be the same

[spark steppe]

the delay is unnecessary and i'm 99,9% sure that it adds unnecessary cost

[trim matrix]

fair enough

[spark steppe]

also it feels unpredictable to determine when it will actually run, it's likely luck that it runs in the correct moment

[solid needle]

directions are held like so

[spark steppe]

you are still connecting multiple things to a pure node

[solid needle]

now that i think about it, i can just make it into an enum

[spark steppe]

your problem is that EACH connection on that pure node rolls another random element

[solid needle]

yeah, thats my issue

is there a way I can use that number elsewhere

[spark steppe]

so store the random result once as variable and use the variable if you need it multiple times...

[solid needle]

off this?

[river schooner]

ty @spark steppe anyways

[solid needle]

what did i do

@spark steppe thank you

ill try it now

[river schooner]

he helped me understanding the not understandable even if i dont understand yet

[solid needle]

i didnt know that works that way

[solid needle]

wat

[river schooner]

aall actors are loading so all the references should be good, do you think that the arraw is none cuz there's not enough time to load the actors? @spark steppe

[spark steppe]

no

[river schooner]

is there a way to find the new actors with their old reference?

[sweet silo]

hi there is it possible to reuse unreal capabilities for example foliage and stuff to create something like the editor but in a standalone application ?
I'm explaining better, i'm creating a storyboard software and i need to create landscapes and foliage but i want people to be able to do it inside my software. how would that work ? thanks a lot

[river schooner]

@spark steppe it seems like the array is already empty before putting it into the save game object

[trim matrix]

Something isn't right now

This is all i've changed

it seems however some how the speed has shot up

[spark steppe]

no

[trim matrix]

and when it's not moving it's still printing that it is

[random pulsar]

When i open the inventory by esc or p the sound plays but when i close it i want to remove that sound ,how can i do this?

[distant hollow]

Use Prints along the way to see at which point did they go missing

[fringe wasp]

Hi everyone, I'm new to Unreal, I'm currently trying to figure out a character controller for an isometric prototype and have run into a bit of a problem. I rotate the character every frame using the "Set control rotation" node, when I move diagonally on the keyboard and release the keys with minimal delay, the character rotates towards the last released key. You can see it on the video, I added an arrow for clarity. Probably a stupid question, but how can I avoid this and make the character less responsive? I've tried turning it only while moving, but then the character doesn't turn around a full 180/90 degrees when keys are pressed, and that's a bit of a different behavior than I want.

[versed sun]

try this

[trim matrix]

arr thats unfuar

*unfair

I can't put it in a function else it messes up the speed it throws out

[random pulsar]

niiice,thanks

[lime crow]

I'm a bit stuck here, i am trying to carry lives over to the next level, i have it set up in the game instance and know it is working because I do a print string, but it's not updating on the hud and i have no idea why, because the logic is in the game instance

[random pulsar]

i have also a ui button on click event and i added this code,it works ok but i think there is a better way to do this ,also when i finish and exit game an error appears

[versed sun]

Save the result of your Get when you Construct

[distant hollow]

Use a Validated Get

[random pulsar]

this?

[versed sun]

like this

[river schooner]

wtfff

watch some tutorials bro

[distant hollow]

We have all been novice before.

We won't know what we don't know.

[river schooner]

True.

[distant hollow]

Where is your code for activating the next level?

[random pulsar]

nice,thanks.Thats it for today😁

[lime crow]

sorry there was more, the logic is ok its just not carrying over

[versed sun]

Save the Ref to you W_PlayerHUD once on Construct, and use that Ref for everything

[distant hollow]

So "Lives" is a variable in Game Instance; where is your code in the new level that tries to get the Lives?

[river schooner]

btw it is completly random

[distant hollow]

wdym

[river schooner]

when i use it here, it will save properly but the array will be empty

when i use it here, the array has something but it doesnt save

[lime crow]

there is no code in the new level, i thought that because its stored in the game instance it will carry over, but im assuming now i will need to call the lives variable from within the level blueprint of the next level?

[distant hollow]

Yes, you would need to

[lime crow]

i did try that, to no avail

[distant hollow]

On the next level on BeginPlay or Contruct, just call the Lives variable from the GameInstance again.

I am presuming you have a different variable in your HUD instead of referring to GameInstance all the time

[lime crow]

I was pretty sure you didnt have to call lives like that using game instance, but i am a bit of a noob, the lives are stored so it does make sense to update the widget on the new level

[distant hollow]

Remember that your widget is separate from the GameInstance

[lime crow]

O yeah i have a separte variable

[distant hollow]

So if your widget is not being updated with the info from the GameInstance then it naturally wouldn't display what's in GameInstance.

[distant hollow]

GameInstance does keep the data intact on level change, but if you don't access it then it carries no meaning.

[lime crow]

thanks man , that all makes sense, i will try an update the level bp just now

[proper flower]

hello, someone can solve this problem?

cast failed

[river schooner]

show more

[proper flower]

the rest is irrelevant, I need to clarify which object connect to the cast to

i used actor object reference

but cast failed

[fleet canyon]

Is it possible to have an image and detect mouse click only if user clicks on white part of image? (and e.g. rest is transparent)

[lime crow]

im sorry for being such a noob, i feel like im on the right track but missing somthing

[distant hollow]

It is relevant, esp how you obtained Actor.

[proper flower]

okay

i'm in the blueprint of an asteroid entity

3 asteroid entities are spawned in an asteroid field(box collision)

[distant hollow]

And what did you set to the Actor? If you did not set anything then it's going to be Null and thus cast would fail.

[proper flower]

what do you mean

[distant hollow]

Your Actor is merely an Object Reference; you need to point it to refer to something. What is it referring to now?

[proper flower]

if for example I use actor reference directly to asteroid 1, then it shows info of redundant

[lime crow]

i need to get the lives from the hud or the game instance?

[distant hollow]

You are trying to cast it to Asteroid_Field right?

[proper flower]

in this blueprint, i use cast to aasteroid field

trying to obtain lifespan

in order to set 1 lifespan for all the different types of asteroids as variable

[distant hollow]

Is the Asteroid_Field going to be something fixed, or it is going to change?

[proper flower]

asteroid field is a box that have infos about spawn timing etc

and spawn asteroid in random rotation and positions

[distant hollow]

Is it an Actor in the scene? Is there more than one Asteroid_Field actors in the scene?

[proper flower]

only one asteroid field on the scene that spawn many asteroid_Spiky and other types

[river schooner]

hi, can I save a actor reference in a save game object?

[lime crow]

Dosent seem to carry over?

[river schooner]

begin play = only setting up vars

[distant hollow]

Then you can use a Get Actor of Class (Asteroid_Field), then set the Actor variable to the output of the Get Actor

You won't even need to cast after that.

[digital valve]

Right you are about the client

[distant hollow]

Drag out from Get (array) > Set Lives Number, plug Lives in as the value

[distant hollow]

I don't think you can

It will return null

[river schooner]

yea that's whats happening

[distant hollow]

You will need to respawn them

[river schooner]

respawn?

[urban coral]

Hey, can someone help me with this? I want my playercharacter's capsule collider + camera to scale/adjust themselves automatically at the start of each level, effectively making the player taller each level (because each level takes place during a different stage of the character's life), but the way I viz-coded it, it's not working, and Im not sure why.

[lime crow]

i can only get and set lives from the target?

[distant hollow]

Respawn when you reload
Save the other information of the actor separately

[distant hollow]

What you were previously doing is basically setting the same value to the same variable, meaning doing nothing

[distant hollow]

You need to get Lives (from GameInstance) and set as the value to "Lives Number" (from widget).

[river schooner]

so here I am spawning each actor back in the game but the child array will bev empty, how do I use it correctly and set it correctly?

[distant hollow]

You can't, it wouldn't work.
Instead of the childactor array you'll need to separately create like a Struct, then save an array of that Struct based on the childactors information as part of the SaveBuildables

IE. Struct within a struct

[spark steppe]

https://tenor.com/view/breaking-news-news-flash-report-gif-8607328

[river schooner]

stop ben lol

[distant hollow]

s_childActor (array), then add it as a "childActor" variable of type (s_childActor) array to your s_SaveBuildable struct.

[river schooner]

so i should create a struct in the struct

[distant hollow]

Yes, if you want to save the data

[spark steppe]

Mags #blueprint message

[river schooner]

bruh

[river schooner]

you dont know how much I would love to solve thwe problem man

[urban coral]

but im not in a rush, so Im just watching the conversation between Alex and Ray

[distant hollow]

Wait - where did you create the new HUD widget in your new level?

If you load a new level the previous HUD would be destroyed.

[lime crow]

the hud remains on the next level

[distant hollow]

Everything including HUD is destroyed on new level load

[distant hollow]

And what does your ChildArrayStruct looks like?

[river schooner]

.

a normal array

[distant hollow]

If you are seeing the same HUD, it was actually respawned.

[distant hollow]

You cannot save Actor References, I told you that.

[lime crow]

im going to create a new level now to test

[spark steppe]

here we go again...

[river schooner]

then what am i supposed to put there

[distant hollow]

One possibility is that the HUD is not created yet
You can try setting a Delay before the Get All Widgets of Class

[lime crow]

tried a one second delay before

[distant hollow]

What are the information you want to keep about the ChildActor?
You need to put all of them in a Struct.

[river schooner]

do i need to put there the mesh, location and these kind of stuff?

[distant hollow]

Yes. Whatever info you want to keep about the childactor.
You cannot expect to just have an Actor reference and that it would save everything about that actor.

It would not happen.

[distant hollow]

Try using a longer delay and see if it works

Start with 5 seconds

If that didn't work then it has nothing to do with load time

[river schooner]

ty, you are really helpful

[spark steppe]

ffs i told you the exact same thing 3 times, 2 hours ago

[river schooner]

not in a way that I could understand, i was so confused before

just say: you cant save an entire actor but you can save his propreties

[barren tangle]

Hi, the Max Walk Speed is the max speed all axis?
If my Max Walk Speed = 1000m/s and i only have an Horizontal movement (X) i will move on the X axis at 1000m/s.
If i add a vertical movement Y. That's mean my movement will try to reach the Max Walk Speed (1000) but on the 2 axis. that's mean my speed on the X axis will slow down.

Is there a way, to have max 1000 on both axis, X and Y but without sharing the max Walk Speed?

[distant hollow]

Just apologize and turn the page; we were all noob once. You were telling someone "watch tutorials" earlier on too, that's not too helpful either.

[river schooner]

lmao, you are right, ty for both of you

[river schooner]

how long have you been using unreal? cuz you are good

[distant hollow]

I'm still quite novice actually, only better at specific aspects. Been on it for like 1 yr + only.

[lime crow]

this is a nighmare, i think the hud is persistant

[river schooner]

nice, I have been using it for a month

[distant hollow]

It just happens that what you encountered is what I encountered and hence I could advice

[distant hollow]

Am quite sure it isn't

How did the delay work?

[lime crow]

it didnt im afraid, got rid of the error mind you

[distant hollow]

If it got rid of the error that means it is indeed a load time issue

So the Lives number still doesn't show up?

Show your code

[distant hollow]

Slight mistake

Drag out from here, type "Set Lives Number"

[spark steppe]

i wouldn't replicate the lives to the widget if you already store them in the gameinstance

you could just get the amount of lives from the game instance in your widget!?

[distant hollow]

I'm assuming he is going to display them in the widget

Right - what exactly is the Lives Number component to begin with?

[spark steppe]

yes, but having the "same" data in 10 different places is like a subscription to chaos

[distant hollow]

@lime crow can you show your widget blueprint?

[tiny wing]

may be you could set this function inside the widget on begin play like, get game instance and set value to variable . it will set the value when you creating the widget. eg:- you are loading new level, On begin play of the level, create widget and add to view port.

[spark steppe]

replace this by a foreach loop, just to check if you maybe have 2 instances of your HUD around

just to nail down why it behaves weird in the first place, still i wouldn't suggest to use the gameinstance just to carry data over from one level to another

[lime crow]

yeah thats no a bad idea, my head is pickled from this right now

[distant hollow]

Change this to :
Get GameInstance_Cast > Get Lives, plug it to ToText (integer)

Insert a Sequence node here:

1 continues to cast to GameMode as it is
2 call Get Lives Number Text

And return the values to this

This should initialize things based on your GameInstance data.

[lime crow]

Bit lost on that sequence step

[distant hollow]

You already have the variable "GameInstance_Cast" on your BeginPlay so you don't have to cast again
Drag that in, then from it drag out "Lives"

[spark steppe]

sure?

compile it, it shows a blue note if it's already casted

[distant hollow]

Go to your Design and show me what is the LivesNumber componenet

[lime crow]

shit

it worked

hold on

That fixed it!!!

hold on dude should i change it?

[distant hollow]

You don't have to cast again here, you can simply use the "GameInstance_Cast" variable which you have defined under BeginPlay.

[lime crow]

i cant i get loads of errors if i dont cast?

[distant hollow]

Are you running the Get Lives Number Text on Tick?

[lime crow]

it looks that way but no

[distant hollow]

Right click on the GameInstance_Cast and set it to a Validated Get

[tiny wing]

Move the game instance cast before the delay

[tiny wing]

that may fix this

[distant hollow]

Oh right, there was a delay

[lime crow]

o that worked

[distant hollow]

So now you can remove the delay

[jade prairie]

Hello guys, I was saving according to the tutorial, and I got this error after saving, it refers to Add that the input variable Actor cannot be written, the author of the video said that you need to turn off physics and remove unnecessary elements from the structure, I removed it, but that's don't work. I will be grateful for your help

[distant hollow]

And use Validated Get for the GameInstance_cast variable in the GetLivesNumber instead
