blueprint

[chilly plover]

Is now just the number format?

[frosty heron]

You can convert int to string

do as you please

[wanton radish]

how to change gravity scale for actor?

[chilly plover]

Basically I am trying to output a string: 22/01/2024 22:59PM

[frosty heron]

well this only gonna print hour min second

format it to your need

[chilly plover]

Thanks so much mate

[chilly plover]

For loading a game I am meant to loop through the game slots to list them?

[frosty heron]

depending on your design

[chilly plover]

I basically want a widget with all the slot saves in it

so I can click them to load it

[tranquil lagoon]

I am working on an appearence system, and it works by me having 4 different struct variables in a save game blueprint (BGS_Appearance)
I then call a function called "Save Appearance" to set the different structs before saving the game to the slot

However, for some reason, only one of the structs actually saves properly, while the rest are just empty.

[frosty heron]

yea that's pretty easy

you can have a save file that contains all of your slot

everytime you create a new slot, just add to it

you can get the save file that contain all of your slots then display them on the widget

[chilly plover]

How do I load the slots to the screen?

[frosty heron]

#blueprint message

@tranquil lagoon I hope that's not BP struct, you will end up corrupting your project sooner or later

[dark drum]

When you get an infinite loop message and it takes you to this... UE is so helpful sometimes lol.

[tranquil lagoon]

What do you mean BP struct?

[frosty heron]

Is the struct declared in blueprint or cpp?

[tranquil lagoon]

It's a Blueprint?

[frosty heron]

Yeah

[tranquil lagoon]

Is that a problem?

[frosty heron]

it is actually

Bp struct is broken since forever

[tranquil lagoon]

Really? That sounds very weird that they'd not fix it?

[frosty heron]

they still haven;t fix it, problem presist

[tranquil lagoon]

Whats the problem

[frosty heron]

All types of problem, mainly corruption

it's like taking a walk to minefield, one day it just stop working

there are victims at least every week

editing bp struct especially making it prone to break it

if u need to add more member variable for example

sometime it just get corrupted and you can't compile your project anymore.

[dark drum]

If you don't ever change anything on the struct once you start using it you'll probably be fine but the moment you want to add a new var, rename, change type etc... you need to perform a sacrifice.

I still use BP structs but you just need to be careful with them. Especially if you have a lot of vars in them.

[turbid pecan]

hey guys, quick one about best practices:

When you have "Event BeginPlay" it can only produce one Exec noodle. Meaning I cannot connect it to two distinct sets of behaviour simultaneously. Is the best practice to connect it to one set, and use the final exec event's noodle from this set to then connect to the other exec event of another behaviour or to use something like a sequence node?

[dark drum]

It doesn't matter. Which ever is the easiest to follow.

[dark drum]

All though with you asking, i can only assume you have some sort of monstrosity so a better question might be how can you make what you're doing more efficient. 😉 (less nodes)

Out of curiosity, what are you doing? lol

[turbid pecan]

Nothing horrible. Lemme screenshot it for you

Wanted to keep the input mapping of the controller intact for beginplay

but also need to loop over the trigger boxes in the level (which this controller will always be part of) to turn the character by 90 deg either way based on which direction the player hit those

the hits need work, they are a bit wonky so I need to math it out

but overall this seems to do what is needed

[frosty heron]

so what are u worried about?

if it looks too cluttering, just collapse them to nodes

[turbid pecan]

Not worried, I just wanted to know whether what I am doing now goes against best practice or if it is okay. And whether a sequence node just after begin play is a preferred method over what i am doing

If I had another set of behaviour for the beginplay then id probably seq it, but atm if this isnt considered stupid then ill leave it

[dark drum]

Yea that's not bad. Personally, I would make the Custom Event a function (unless you need to rep it) and use a create event node for the bind (selecting the function). I'd probably then collapse the whole loop into a function. Some say not to use functions for things that only get called once but meh... I priorities readability lol. I don't know how long it'll be until i return to it.

[turbid pecan]

Added your message as a comment above it. When I tidy up ill try to do that

Atm just trying to not fudge up too much along the path to being less of a idiot

Still getting used to how stuff works in unreal, so all of this is kinda new.

[rugged wigeon]

Don't use functions for things that only get called once. Use collapsed nodes with a long descriptive name

much more readable

[turbid pecan]

public static main string void args

Dont tempt me

[dark drum]

I'm not a fan of collapsed nodes so i wouldn't say it's more readable. 😉

[turbid pecan]

Im trying to avoid diggig into C++ side for as long as I can. I enjoy writing c++ but never wrote a line for unreal

I think i wouldn't fare better than BP at this stage

Nor does it need it atm

I think

[rugged wigeon]

collapsed nodes are wonderful. BPs are good for writing, but suck for reading implementation details. Ergo, hide the implementation details and let people just read what the code does without reading how:

[turbid pecan]

The thing with collapsed nodes for me personally is it encourages hiding the internals

[rugged wigeon]

you can also make great use of negative space for branching:

[rugged wigeon]

That's a good thing!

[turbid pecan]

like if its a huge graph inside that node - it makes sense to hide it. But if its stuff that isnt too bad, I personally prefer everything at a glance

[rugged wigeon]

you only want to see internals of a thing if you're double clicking into it. and if you're double clicking into it, its the only thing you want to see

[frosty heron]

the level of abstraction is for you to decide

[turbid pecan]

This is coming from someone who avoids OOP as much as possible

[frosty heron]

though the smart people say, one of the bp downfall is that it become spaghetti rather quickly

[turbid pecan]

I am not a fan of abstractions after certain points nor the way inheritance is done these days

[frosty heron]

what are u talking about. BP is also OOP

[turbid pecan]

its a personal thing

[rugged wigeon]

you don't want to hide a "huge graph". hiding graphs because they're big is wrong. Hiding discrete tasks is what you want

[turbid pecan]

Sure, but you dont get to choose the starting point. You get to only increase the abstraction

[rugged wigeon]

collapsed nodes are not abstraction, they're just organization

[turbid pecan]

And also - I did say "avoid" which isn't always possible

[frosty heron]

i agree with this, though probably not qualified to have opinion on the matter

[turbid pecan]

Well they visually abstract the inner workings of whats inside until you dig into it

again, its a PoV thing

😛

[dark drum]

Yea but i look for stuff using function names that are in categories. Much easier for me to find what I want.

[rugged wigeon]

if something is used only once, you don't need to ever look for it. Collapsed nodes are for hiding implementation details, not creating functionality that will be reused ever.

storing a bunch of one time use code details in function names just to make your event graph less spaghetti means you'll have a cluttered name space

[astral geode]

Hey does someone know why this bool isn't getting changed even if it changed from false to true even tho its being made true before its gotten

They are both from different BP feel free to ping me

[turbid pecan]

I feel like I started a war

its all preference

you like what you like, use what you use

s'all good

[dark drum]

But I might end up using it again. Who knows what I think of in a weeks time. Adding to that, bugs often arise and in a lot of case I'll be 'Oh that'll be X in such and such function'.

[rugged wigeon]

then it should become a function at that point

[digital palm]

I have a issue with physical surface. In editor, enum to string from Surface Type give me Metal, but in dev build, its give me SurfaceType1, any idea?

[dark drum]

Just think of all the accidental duplicated code that's been collapsed away and forgotten. 😛

[rugged wigeon]

it's not really all good though. People often malign tools that are beginner friendly because 99% of what gets made in it is made by beginners with poor sense. That's not a good argument, because if the tools were not beginner friendly, nothing would get made at all. But that's still a sign that one should strongly encourage the best practices with beginner friendly tools.

[turbid pecan]

Well you are certainly entitled to that view. Im okay with that

No gripe from my side

[rugged wigeon]

I can't see how this is any more likely than someone writing the same function twice

unless they collapsed poorly

[rugged wigeon]

your execution pin goes from tick to get all actors and then stops. so every tick it gets all actors and does nothing

white pin is execution pin. It shows what order things get done in. The rest of the pins are just data flows that could get used if a node gets executed that needs them as input.

[frosty heron]

Don't connect nodes like that

[rugged wigeon]

enums lose their string values outside the editor 😐

[digital palm]

fak, any solution?

[rugged wigeon]

dumbest, quickest solution is to just pipe it through a map that spits out the string value you want

[digital palm]

well yea I think so :/

[rugged wigeon]

probably you can be cleaner about it doing something like a switch on enum value but it really depends what you're doing and how built up it is already and how annoying that would be to change

[summer pewter]

hey all, i was wondering how i would implement a group spawning system. i need to spawn packs of enemies around the player. would i iterate through an array of actor classes or create blueprints for each individual group with the enemies being child actors? any ideas welcome

[rugged wigeon]

definitely the first

[summer pewter]

kk cheers ill figure something out

[rugged wigeon]

If it's as simple as spawning each element from an array of classes just do that. If you need more details, probably make a struct to represent "group spawn data"

mine looks like this: ```cpp

USTRUCT(BlueprintType)
struct FEnemyWaveCard : public FTableRowBase
{
GENERATED_BODY()

UPROPERTY(EditAnywhere, BlueprintReadWrite)
TArray<TSubclassOf<AUnit_Base>> EnemySpawns;

UPROPERTY(EditAnywhere, BlueprintReadWrite)
int Cost;

FEnemyWaveCard()
{
    EnemySpawns = TArray<TSubclassOf<AUnit_Base>>();
    Cost = 1;
};

FEnemyWaveCard(TArray<TSubclassOf<AUnit_Base>> inEnemySpawns, int inCost) {
    EnemySpawns = inEnemySpawns;
    Cost = inCost;
}

};```

structs are a good place to dip your toes in cpp

[summer pewter]

yeah i figured it out using bp. i have my array of actors stored on the game mode which can be updated by player level and map location, just does a random point in navigable radius from the player location into a for loop which has another random loc and the spawn function. everything random is from the character's random stream

[astral geode]

I am trying geometry script, does anyone know how to get correct collision mesh without baking it to static mesh?

[stoic palm]

One message removed from a suspended account.

[proper vigil]

@dark drum For your ultimate dialog, I'm trying to make it so when the objective is different, the convo between player and NPC is different, and I duplicated some things including making a Switch on Enum_DialogState2. However, the "Add Dialog" node's state is unable to be dragged into the selection for the switch on 2, but it could for the original one.

I am not sure how to fix this.

[chilly plover]

So is it possible to loop through all saved slot files?

[dire frost]

Nope. You need to know the slot name before hand. You can make a naming scheme like "slot1, a
Slot2...ect" if you want find all the saved files or something

[grave apex]

what variable type do I need to access these assets?

cuz I know this is the type, but I have no idea how to manually create a variable with this type

[spark steppe]

you can't really, a workaround is to use a load level node, drag from the world input and promote to a variable

[grave apex]

yeah that's what I did

but i need to be able to put this variable in a struct

[spark steppe]

time to learn C++ i guess :>

[grave apex]

some people earlier were telling me that I could use c++ to get it somehow

but

wouldnt that mean i'd have to rebuild the entire project?

with VS?

[spark steppe]

🤷

[grave apex]

do you know how to do it in c++?

[spark steppe]

yesn't

i would have to lookup the variable type

[grave apex]

someone said it was TSoftObjectPtr<UWorld> Level

[spark steppe]

yea that sounds about right

[grave apex]

what do you do with that?

[spark steppe]

you put it in a C++ unreal struct

[grave apex]

would you mind showing me how?

I have VS installed

with all the c++ prereqs

this is a blueprint project tho, no cpp yet

[spark steppe]

create a header file MyHeader.h

#pragma once
#include "MyHeader.generated.h"

USTRUCT(BlueprintType)
struct FMyLevelStruct {
  GENERATED_BODY()

  UPROPERTY(BlueprintReadWrite, EditAnywhere)
  TSoftObjectPtr<UWorld> Level;
};

[grave apex]

#blueprint message (that's what people were saying before, but idk how any of that works)

[spark steppe]

if i didn't make any syntax errors it should compile... (and you should see MyLevelStruct in blueprints as datatype for variables)

[grave apex]

where's that in the add menu?

[spark steppe]

create the header in VS

[grave apex]

should VS have launched with the engine?

or do I just do this in the file browser?

[spark steppe]

i don't know how VS works on windows, so no idea

it's important to note that you should compile C++ stuff always when the editor is closed for now (until you learned enough about live coding (see the pinned posts in #cpp))

[grave apex]

I mean like, does it even matter if I use VS at all? or can I just use any text editor?

[spark steppe]

you can just use a text editor, but you still have to invoke the unreal build tool somehow, so that it compiles the source

[grave apex]

For reference, I know c++, but not unreal's cpp at all, Ive only ever worked with bp. I just have the prereqs installed

Ive never used it

would it be like, here?

[lofty rapids]

what are you making in #cpp ?

oh a struct

[spark steppe]

NO

don't create it in unreal

[grave apex]

o

i guess ill move it to #cpp

[chilly plover]

Hello everyone, I'm seeking assistance with retargeting a third-person character skeleton to a custom skeleton. After organizing and naming different groups of bones and ensuring the same chain in each IK rig, I proceeded to retarget them to each other. Everything seems to be functioning as expected, except for the arms which appear as if the character is restrained with hands behind their back.

I've attempted to adjust the retarget root to different settings in the hopes of achieving a different outcome, but unfortunately, it hasn't resolved the issue. My knowledge on this topic has reached its limits, prompting me to reach out for help. I appreciate your time in reading this, and any assistance provided. Thank you.

[true valve]

did i forget to enable GenerateHitEvents?

nvm

Hi - so can you help me with thi

[eternal totem]

is it possible to return a vector of the average center of a material on a static mesh? I'm trying to input the material id of a static mesh and then use the center location of the material to linetrace to the player.

[lost wolf]

how often do you do this

you don't need the average of every vertex

you just need a point

it's better to just add a point in your blueprint and get that point or to have a (fixed) offset that you can adjust if that's needed

if you absolutely do not wish to store a point into your actor or if you want to calculate it to store it you get the the edges of your bounding box and take the middle of those

you can't loop through seperate vertices of a model to calculate their average position in bp

[eternal totem]

I need it just a single time, the location wont move per instance.
In a component I am inputting a ceiling static mesh
I get length of material element index
for loop through the meshs material indexs
if material equal to specific material name
return global vector
from there do a bunch of stuff to see whether or not the player is looking towards that vector, linetrace for if player behind wall, close enough distance and turn the light material on/off

I'll be going through a lot of ceiling lights, thats why I made a component out of it for each ceiling mesh.
Then in another 3D software I can assign each ceiling light to a seperate material ID.
I'm trying to using only lumen/emissive materials to light my interior w/o any other light except for the player so this is my best solution to optimizing.

[echo wren]

Why is my blueprint of the same class type of this variable not able to be selected in this variable?

im dumb and i get it, i was not passing it a reference, i was passing the static class. so i needed to create/construct a new object of that class then i pass it to that variable.

[uncut vigil]

Is there a simple method in blueprints to make an APawn "materialize" or fade in over time? I know little to nothing with animations and not enough of Blueprints to know what to do exactly. Mainly just C++ coding on my part

[hard palm]

Hi, I'm facing a strange problem, when I play the project with two players the server player camera start looking to the horizon, the game has basically no logic running, It's only a pawn with a camera and two player starts on the scene

[lunar sleet]

For #multiplayer you want to ask in that channel

[hard palm]

Oh, ok, thanks

[frail onyx]

anyone know why im gettting this error

Blueprint Runtime Error: "Accessed None trying to read property VendingMachine". Node: Spin Machine Graph: EventGraph Function: Execute Ubergraph Sound Button Blueprint: SoundButton

[lunar sleet]

Yes. You didn’t properly set whatever VendingMachine is

Or rather the object it belongs to

[frail onyx]

these are some images of the code if that helps, im pretty sure i have it assigned there from my button blueprint which activates my event in my vending machine blueprint

[lunar sleet]

Where are you setting VendingMachine?

[frail onyx]

uh im not sure why it isnt working, i have the vending machine plugged into into spin machine

is there something more i have to do than that?

[lunar sleet]

So nowhere

What is this vending machine variable

[frail onyx]

my vending machine blueprint

and the event is spin machine

which is in my vending machine blueprint

[lunar sleet]

So you’re trying to communicate with another bp?

[frail onyx]

yes

[lunar sleet]

Does it exist in your world? Are you interacting with it?

[frail onyx]

yeah

every thing else works it just doesnt call the spin machine function at the end

[lunar sleet]

Ok, so you can’t just create an empty variable of that class, you need to get the instance

[frail onyx]

like the first picture is from my button blueprint

and the second picture if from my vending machine blueprint

and im activating the button blueprint my from first person bp with a button interaction system i have setup

[lunar sleet]

You need to use a line trace or an overlap, get the hit actor, Cast to your vending machine bp, then grab that return value and promote that to a variable that you can then name VendingMachine or w/e

And watch the bp comms live training at the bottom of the pins so you understand how this stuff works

[frail onyx]

does get all actors of class work and plugging that into my function?

[frail onyx]

anyone know how i can make this spin an additional 90 degrees each time i interact

so it turns 90 degrees stops and then when i press my button again it will spin another 90 degrees from where its at and repeat

[uncut vigil]

Maybe a blueprint method like AddRelativeRotation?

[frail onyx]

ooh ok do you know how i would implement that with my timeline so it goes smoothly?

[uncut vigil]

I've never worked with timelines, but I would assume just adding the method connected to the "Update" node on the timeline would be fine. Also the method for actor would be https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Transformation/AddActorWorldRotation/

[frail onyx]

alr thx i see if i can get that implemented

[iron furnace]

Im currently running into an issue right now where ive enabled simulated physics on certain bones so they droop, but they do not move or droop down. I have the bone names correct, any ideas? thank you

[uncut vigil]

I think you would want something similar like this, since you are using that Lerp method there. Just change to use Rotators instead of Transforms (I just took this example from internet)

[frail onyx]

ok thanks

[round wind]

So if I'm trying to make a game where you can unlock abilities as you go on throughout the game such as dash, energy shield, etc. would making a Master Blueprint Component (similar to whats mentioned here in 2018: https://forums.unrealengine.com/t/most-optimal-method-for-unlockable-abilities/424676/2) be the best way to do it or is there a better method you all would recommend?

[spark steppe]

let me introduce you to the well beloved https://docs.unrealengine.com/5.3/en-US/gameplay-ability-system-for-unreal-engine/

but idk how usable that is with blueprint only

[round wind]

Yeah I was debating if that was going to be worth it. I'm just trying to make an interchangable abilities (to be binded to different keys and swapped) and I think GAS is the way to go but I was hoping to stay with BP.

Also its a 2D game so again, idk if its worth it? Might be overkill

[frail onyx]

anyone know how to make it so when i click my button twice before the timeline is fully finished itll like continue to go to the second rotation location, kinda like most games have it when ur interacting with a button u can click a few times fast before it's finished and it'll make you move like 3 tabs over or something for a menu. So like if i click once itll rotate 90 degrees but if i click twice fast before its fully rotated itll rotate 90 degrees twice to go the second position

[lunar sleet]

Depends, it’s a lazy way doing it and kinda overkill if you only have one vending machine. And silly if you only want to interact with one machine’s function instead of all them

Take the time to learn proper bp comms, you won’t get far without it

[lunar sleet]

I think you can use the Set New Time pin with a time input to skip ahead

[compact sandal]

hi, why does this stuff appear when i try debug viewing a line trace?

sorry, here

is this a bug?

[austere ingot]

does anyone know of a way to test collision against something without using Generate Overlap Events? trying to do a building system, all of the objects have a box collision for their size, but unless the object they're colliding with has Generate Overlap Events on, it can be built while clipping

[steady night]

how would i check if elixir timer reached amount

guessing have to do own logic

[dark drum]

What do you mean by reached amount? Amount of what?

[steady night]

yeah nevermind i was just being dumb

[dark drum]

Yes. UE uses the metric system. I'm pretty sure the velocity vector is per second.

[gentle urchin]

Not sure what this logic does ?

Even in theory

[dark drum]

You can use the get overlapping actors/components node. I believe this will still populate regardless of whether generate overlap events is enabled. You would need to come up with the logic to use and handle the data though.

There's lots of ways you could do it. Reducing gravity during the wall run is a perfectly valid option.

[queen heron]

I'm tryna get the rotation speed of the spring arm, but the rotation does not go beyond -180 and 180, instead it flips and messes up the interpolation I want to achieve on the camera

[dark drum]

I would use a rotator and use rinterp.

[queen heron]

you mean like rotation variables?

[dark drum]

Yea.

[queen heron]

hmm, lets see

[dark drum]

If you have a yaw value of 170 and combine another rotator with a yaw of 30, it'll wrap to -160.

Well it will when it's applied. Rotations can be a little finaky but using a rotator helps.

[wicked magnet]

Hi is there a reason why the sound keeps playing?

Does play sound somehow make multiple instances or sumthn?

[dark drum]

Yes because the delay doesn't delay the for loop. The stop sound is called before the sound even starts playing.

[wicked magnet]

you sure? if it doesn't delay the loop wouldn't I be missing some loops? because that's not the case afaik

[queen heron]

nop, still the same issue, not going below -180 and above 180

[tribal stream]

Hello everyone

What I wanna do is spawn a bunch of collectable items in different locations without repetition from an array of locations I already made.
I tried shuffle and many other solutions, but it doesn't work as intended and sometimes it still spawns more than 1 item in the same location (which is not what I want)
BTW this is all done inside a spawner function which I call many times to spawn the items.

How can I do that?

[dark drum]

Yes, 100%. Every thing after the delay just gets called X amount of time after the loop has actually finished.

[wicked magnet]

maybe remove the location from the array when an item spawns there?

[tribal stream]

I tried removing the array item after it was spawned, and the issue still persisted (I saw someone on reddit saying the same thing too, that it doesn't work)

[tribal stream]

will test it again just in case though

[dark drum]

You need to store the random int in a var and use the var. Using the same random int in range would just make it generate a new int and remove the wrong one.

[tribal stream]

You mean storing the result of random integer in range in a variable?

[gentle urchin]

Only once , but yeah

[dark drum]

Yes.

[gentle urchin]

Rest of the loops are ignored

Oh sorry. I even misread what you said

X amount of time not X times

[dark drum]

It happens lol. I do it more than I care to admit haha.

[tribal stream]

Ok, so where do I use the var?
Should I remove an index from the array element using it?

[dark drum]

Use the var for the int on the get and when done remove index from the array.

Also, you might want to set the max for the random int to be the last index of the array so it always stays in bounds.

[queen heron]

ok, so it turns out that RInterp To is what flips the angle between 180 and -180

setting the rotation speed without it actually gives angle values beyond those

[dark drum]

What is it you're trying to achieve anyway?

[tribal stream]

Ok this is probably it
Will test it and see if it works

[queen heron]

I wanna make the camera rotate further away from the spring arm depending on the spring arm's rotation speed

[dark drum]

Yea that'll work. As an extra tip, get your array, pull from it and search for get last index. 😉

[dark drum]

What triggers the rotation? Player input?

[queen heron]

yeah, with the mouse

the result seem to look a bit better

[ember vale]

heyy guys, what is better for aim offset? with animations of procedural method?

[dark drum]

#animation

You'll probably get a better answer in there.

[queen heron]

tho there does seem to be a bit of snapping when reaching a certain world rotation

right, because the spring arm is still limited to -180 180

this is how I'm rotating the spring arm

[gentle urchin]

Shouldnt be much snapping because of that specifically

Its just normalizing the rotation, nothing else

[queen heron]

the way it snaps is, it quickly rotates back a few degrees and then catches up with the rotation speed

wait wha... after I connected back the first RInterp To node, the snapping is gone

nvm, it just keeps flipping between positive and negative angle....

[gentle urchin]

Weird as the node should aldready handle that when using delta

Let me check

[tribal stream]

Right now it's working well without spawning duplicates on top of each other
BUT when I'm trying to spawn 6 collectables, it sometimes spawns 5 or 4

[dark drum]

Did you swap out the max integer range for the arrays last index value?

[tribal stream]

also I tried printing the "random integer" and it sometimes prints 36 though it's not in the variable or within the max min range

[tribal stream]

Nope sry
didn't understand this honestly

will give it another shot

[queen heron]

huh, look at that huge jump when it reaches that world angle

what else could I be missing

[tribal stream]

is this what you mean?

[brazen hinge]

Hi guys, I'm new to unreal engine, why do we need to attach the x roll axis on movement when we only need the z yaw axis to rotate towards where we are looking? I have watched a lot of TPS tutorials using this approach. But I decided to detached the connection on x roll axis, the TPS controller seems fine. Help me understand this.

[gentle urchin]

Oh.. I ended up just rotating the Actor for some reason

Its an RTS so doesnt matter much in my case
using RInterpTo

[dark drum]

Yes

[queen heron]

I need to get constant rotation speed without getting that jump in angle when the spring arm gets its rotation flipped

[tribal stream]

IT'S WORKING PERFECTLY NOW!
Thank you, thank you so much. I've been stuck on this for a few days now and I almost went insane lol

One question though:
Why is it working now after swapping the max integer for a last index?

[tribal stream]

@dark drum

[tribal stream]

I thought my setup earlier was technically correct.......

[dark drum]

Because your initial setup didn't account for any changes to the amount of values in the array. If you added a few more you would have had to make sure you updated the max range value as well. Using the last index method allows it to do it automatically. 🙂

[tribal stream]

but I did remove an index from my array, so if my array had 36 values (starting from 0 to 35), doesn't that mean after using "remove index" it should make the array have less values by 1?

Or does it leave that index empty instead of removing it?

This is really confusing

here's what I was talking about

[dark drum]

The issue would have been the 'Max Interger in Range' value. If this was set to 10 but there was 30 elements in the array, it would still only spawn 11 items. (including index 0) Using the last index just means the max value would always reflect how many elements are in the actual array without having to manually update the 'Max Interger in Range' value.

[gentle urchin]

What may be easier is

to make a local copy of the array (if you need the original array for something else),

then shuffle it

and just pick the 10 first indexes

(or 10 last ones, if you're removing as you loop it)

[tribal stream]

Ok so I rewrote the max part now and used decrement instead of minus one, and it works perfectly all the time.

Yes, this method is a bit destructive since you would need to change the max value if you add more elements into the array (which I wouldn't do anyways). But at least I got it to work and will be able to sleep without thinking about it 😂😂
Will use the last index method now

Thanks for the help Michael ❤❤

[queen heron]

I figured out the obvious

I'm so embarassed....

and to make sure the camera rotates back to 0 smoothly, I use Event Tick

[gentle urchin]

Thats what i did aswell,

Its important enough and must be updated per frame for smoothness so 😄

[queen heron]

now to give the mouse input a deadzone to avoid value jumping

if I move the mouse around fast enough, the value will jump like this

oh... I can't clamp the deadzone higher than 1

looks like I'll need to use a clamp float node instead

[burnt obsidian]

Hi, I have made this blueprint that spawn Instanced static mesh components on a spline. Now when I bake the lighting of this the shadows are all the same instead of each having their unique shadows. Am I using the wrong node for doing this job?

[dark drum]

Where do you add a new instance to the component?

[burnt obsidian]

in the event graph

basically I call a function that spawns them

[hybrid ether]

What is best way to get angle to target actor? I would use it to check should AI turn left or right. And if player is between -45 and 45 it doesn't turn at all.

[dark drum]

Show how you do it.

[burnt helm]

You can do a look at function, and the forward vector of the ai/camera, and do a === between them with a tolerance of 0.25

There are cheaper look ats in this case since we dont need rotation

So no look at, but V2 - V1 normalised

[burnt helm]

hi guys, just a quick question, when you create a new index in an array by mistake, is there a way to delete only this index in the array ? Probably a dumb question but I can't find how... thxs

[lilac storm]

Hey devs , please help it is a spaceship and what i want it when i release the Thrust button i want it to stop slow and smooth , i am definetly missing something with this VInterp node could you please correct me ?

[wet patrol]

Hey guys I have a widget switcher for my main menu map where I have the title menu and the main menu as 0 and 1 but when I come back from singleplayer map I want the widget switcher to go to 1. How would I bypass 0?

so this would take me to main menu instead of the title menu

[gentle urchin]

You could do it through game instance

Or by using open level options if main menu is a separate level

[wet patrol]

How would I go about it though? I would like to do it by Boolean BackToMainMenu but don’t know how

[whole jungle]

hey guys, I am trying to implement controller support for menus and I figured out that if I do "Set Focus" with a button, it does allow me to go down and up with my controller or key arrows, but all I get is this vague highlight on the edge
How can I make it the same with the hover functions that highlights the button when I move through the buttons ? (second image)

[cloud spoke]

Did you fix this? I am having that issue with my leg staying up after a kick

[thin panther]

I suggest flexibility exercises

[golden frigate]

y u ping me from 2 years ago 💀

[cloud spoke]

You can see why ahahah

[golden frigate]

ofc i fixed it but i dont remember what i did

[cloud spoke]

alr

[hard palm]

Hi, I'm facing a strange problem, when adding inputs inside Controller it doesn’t work while when adding it on the Pawn it works normally:

[thin panther]

Could be you're not actually using the tank controller

Verify the event tick is being called

[hard palm]

No, it's being called

[void jewel]

I have a blueprint that can execute various scripted anim montages+effects, kind of like abilities (from a specific actor). The player controller should be able to execute these through a function.

Is there a way to make a local enum of sorts? I want to make it so that there's an input variable on this function that decides which ability is fired. Is there a way to do it without having to create a "global" enum? Rather than having a switch based on a int or something

i don't know why i'm hesitant to use enum anyway. I just have a ton of them and suspect i'm using it too much, but shouldn't matter the least i guess?

[faint pasture]

Have Thrust just change a variable, and use that variable to change your speed, and use your speed to change your position, just like every other movement system.

Thrust isn't speed, thrust is RATE OF CHANGE of speed.

Input -> set Thrust

Tick -> Velocity += Thrust + Drag(however you want to do your drag) -> Position += Velocity

You can skip the input event and just directly get the thrust value in tick if you want, that'd be a bit simpler.

A decent simple drag system is just Drag = SomeNegativeNumber x Velocity

[lime crow]

im trying to stop the camera from moving whilst crouching, why wont this work please?

[faint pasture]

What moves your camera usually?

[lime crow]

its the default third person, so the capsule? ahhhhh

[faint pasture]

Probably ControlRotation

None of your code will stop that

[lime crow]

because crouch has inbuilt code to move the camera?

[faint pasture]

you need to instead either NOT modify ControlRotation when crouched, or have the camera boom ignore control rotation when crouched

no

has nothing to do with crouch

[lime crow]

Thanks

[lilac storm]

hey guys ,when i start the game this InputAxis functions got automatically called returning 0 all the time , why it might happen and how to fix it please ?

[thin panther]

that's normal and expected

an input axis runs as a ticking thing

when you're not moving you're moving with a value of 0

[silent drift]

Anyone know why I'm getting the error in the image? The reason I'm asking is that I get the error, but it works the way it should and even trying to log the value through the AnimationBlueprint works.

[lofty rapids]

when do you set it ?

[silent drift]

It is part of the health component on my player and it's set to false from the start, or do you mean where in the anim blueprint?

[lofty rapids]

hmm

[silent drift]

Like here it were it happens:

[lofty rapids]

is it your player reference that accessed none, or the variable ?

[silent drift]

The weird part is that the velocity and all seem to not give me the warning, only the "health" variable.

That is why I'm a bit confused.

[lofty rapids]

hmm

[silent drift]

That above but also that it works and does what it should + prints the correct bool value when being printed.

[calm cargo]

any built in functionality for copying all the components from one actor and putting it in another actor? (property values included)

[faint pasture]

First off don't call it a player reference

is it a pawn? A playercontroller? who knows

[dry scaffold]

Could anyone please help me with implementing a post process effect when I press a letter key? I have a vignette effect which I want to take effect on my screen when I slow down time. I know there's some scalar/vector parameter function but it didnt work for me

[silent drift]

My naming is player for the top (player blueprint) otherwise it's playercontroller, etc.

[faint pasture]

I'd call it MyPawn or MyCharacter if it is one

[tardy ridge]

Is the blueprint simulation visualization broken in 5.3? I have a blueprint which triggers a debug print when a key is pressed. I press the key and the message appears, the blueprint shows it's in "Simulation" mode, with orange borders, but it is not showing the nodes execute as it does in 5.2

Looks broken to me.

[lunar sleet]

Select a debugging object

[tardy ridge]

ah, is that new? didn't have to do that in 5.2

[lunar sleet]

I think it’s been around for a bit. I rmbr not having to do it either, at some point

[tardy ridge]

There are no selectable options in that menu, it also says that if none is selected it will debug "any"

and the debug print appears.

showing that something is executing this BP

[lunar sleet]

You need to hit play first

[tardy ridge]

yes I hit play first lol

[lunar sleet]

Weird

[tardy ridge]

PIE began, player controllable as expected, hit the key, debug message appears, no blueprint visualization

Yeah im calling this crap a bug.

[lunar sleet]

No, I mean hit play and then select debug object

Then on the next execution it’ll rmbr it

[tardy ridge]

still no options in the debug menu after hitting play.

They have really let the quality slip after 4.x

[lunar sleet]

That is odd behaviour indeed

[tardy ridge]

constant regressions

looks like it might just be a bug with the ability system blueprints, because I made an empty actor with a scene component, and hooked a debug event to BeginPlay and it shows that

[lime crow]

i am trying to disable the camera from going down when the player crouches, where am i going wrong?

[hexed cradle]

i think i got an idea of how to use materials on procedural meshes . i should use Vertex Colors.Okay I figured it out well at least in theory .Bassically I need to take my vertices and makes groups of them than create a mesh section for each group and apply a different material on it . It can work with squares but I wanted to make it more complex maybe by using vonoroi noise

[hexed cradle]

To what is your camera boom attached to is it on your charater mesh ?

[lime crow]

yeah its the standard tps, i really want to keep this layout

[hexed cradle]

So you're saying that when you crouch your camera moves down

Do you use the mouvment component crouch or is it just an animation ?

[lime crow]

yeah thats right, that's normal because i set the half-heighti just use the regular crouch function

i read the crouch function moves the camera

[void jewel]

any idea why the other cameras are not showing up on details in the outliner?

[hexed cradle]

Try to verify what setting you disabled on the ones you can't see it s maybe also why they are highlighted in yellow

[void jewel]

The other ones are not set to active, but i'd still like to see them. I need to be able to adjust their position in the viewport accordingly

[hexed cradle]

One option would be to keep your camera to the same height by changing the camera boom offset on the z axis when you're crouched

[gentle urchin]

Guess those can be a bit special

Should still work but ypu got stuff with the instancing policy etc.. may cause some weirdness

[true crater]

Hello guys,
I have considerable experience in Blueprint. How can I take myself further in animation and physics?

[gentle urchin]

Personally i never trust the bp debug mode anyways. It can straight up lie

[hexed cradle]

Fr

[lime crow]

sort of like this?

[hexed cradle]

Like procedural animation and stuff ?

[tardy ridge]

definitely Special

special and outstanding.

[hexed cradle]

Yeah try it out and tell me the result

[tardy ridge]

not the good outstanding though, The outstanding that your drill instructor talks about

[true crater]

IK, Climb, Vault, Push-Pull Mechanics etc.

[lime crow]

it does move the camera but its a bit hard to find the exact value to move it

[true crater]

[dusk saddle]

Can someone maybe tell me why this isn't working?
the interface is working right but it won't spawn the decal on the location provided.

Thanks.

[true crater]

Check "Receive Decals" on your actor

[dusk saddle]

yeah it recevies decals

because I have others on it

[lime crow]

@dusk saddle its the rotation man, i spen weeks working with decals

[faint pasture]

I do that for my material system and it works great.
I use the R channel of vertex color to do my masking, and use material layers

[dusk saddle]

wdym

[true crater]

Decals are one sided

You create a decal on a surface, but maybe it is reversed.

Sorry for my english.

[dusk saddle]

np let me look

[lime crow]

try ue get foward actor, worked well on my fps game

[dusk saddle]

ngl a beginner so not sure what to plug into start

How ? Do you have a tutorial or something I am not really good with materials

[faint pasture]

my man, use a variable lol

[dusk saddle]

yes. but I just want to spawn a text decal

[faint pasture]

that vector node spaghetti is nuts

[hidden yacht]

hello everyone

[dusk saddle]

not firing from a weapon

[lime crow]

hat for?

[hidden yacht]

visuallly satisfying though

[lime crow]

i know it was when i was just starting out and kept building on it

[brazen pike]

It's gonna be expensive too if you do the calculation every time rather than setting a variable

[lime crow]

yeah its old code, i was just showing someone a node

[hidden yacht]

Does anyone know who would an "Enhanced Input Local Player Subsystem" return NONE, (null value) ? it's been driving me nuts for hours now

UE 5.3, EnhancedInput set in project settings (by default)

PlayerController on the input side is not null, i checked

[lime crow]

i still dont know why its not keeping the camera the same?

[brazen pike]

does it work for the client?

[lime crow]

i got that working, but feel its bad practice to do it such a way

[brazen pike]

So what are you trying to do here? You want to stop the camera from moving down when the player crouches?

[lime crow]

yeah, the above works perfectly, but dont think its a good way to do it

[brazen pike]

well if it works it works. But this will break if you change the height of your player.

[dusk saddle]

guess I did something LMFAO

[lime crow]

hes always going to stay the same size

[brazen pike]

then its fine. Don't worry about it

[hidden yacht]

well, I can't tell. A.K.A i don't know how to tell... I'm new to UE, coming from Unity
so far, I can say that when I run the game as client, I spawn the vehicle, then I hit F to enter it, the function on server triggers and gets the player controller to possess the vehicle pawn. Then there is absolutely no control over the vehicle, no mouse/camera movement and no driving controls. basically it does not work at all.

Using the following :

• ThirdPerson mannequin and using its BP "BP_ThirdPersonCharacter" (default one from 3rd person project)
• Vehicles from CitySampleVehicles on the marketplace , using its "BP_Vehicle" file from which all car variants inherit

I have also set :
my own "BP_GM" game mode file, this one has the Enter_Vehicle function
my own "BP_PC" player controller file. this one hits F to enter the vehicle, calls the GM function on server
my own Game state and player state BP files but for now no content in those

When I start the game, the server spawns the ThirdPerson pawn, the player controller here works great, I can move and jump with no issue. I can spawn a vehicle ("V" keyboard key), then hit "F" to enter it, the camera ecnters on the vehicle as I possess it, but then I cannot move at all. not even camera view . on exiting the editor play mode, I had the error saying that "Add Mapping context" node had bad input. After digging here and there, I found the output value of input node to be the issue

[dusk saddle]

So i found this in the settings of the decal
and then I used a divide node

it worked

[brazen pike]

So you must be doing this with the third person character for that one to work. Can you show that code?

[hidden yacht]

I'll show you all BP files

BP_ThirdPersonCharacter

BP_Vehicle

in the BP_Vehicle, I only modified the "Event Possessed" chain

[lusty hedge]

not sure why nothing prints. the trace turns green and shows its hitting... does anyone know how to recieve a trace?

[frosty heron]

OnPosses only called on server

[brazen pike]

Yeah okay. My theory is that "Enhanced Input Local Player Subsystem" doesn't exist on the server, only the local client.

"Event Possessed" is a server-only event, so you won't be able to access "Enhanced Input Local Player Subsystem". Instead try putting an "owning client" RPC directly after "Event Possessed" then doing the same thing you did on the third person character.

[frosty heron]

I use acknowledgePossesion to setup input mapping context for clients

That one is called on clients

[brazen pike]

is that a blueprint or cpp function

[frosty heron]

This probably work too.

[hidden yacht]

The nodes were already there, is it perhaps because the VehicleSample package is not "network ready" ?

[frosty heron]

I dunnoe, I used cpp for the override. Would be surprised if it's not callable in bp

[lusty hedge]

How do i make a box collider recieve a hit from a trace

what event is it?

[frosty heron]

Don't make sense to me to setup input for the client in the server machine

Just do what lemon says

You can try this.

Make a function in your character. Call it setuo input. Move your add input there. Make the function an owning client rpc

On posses, get the controller, get the pawn, cast and call the function

[frosty heron]

Probably on component hit? You are doing overlap btw

Not entirely sure since I never done it

[brazen pike]

it'll work fine if you play singleplayer only. But if you want it to be multiplayer, then it isn't ready

[brazen pike]

Do traces create hit events? I'd assume not

[frosty heron]

I have no idea

[lusty hedge]

neither works

[hidden yacht]

The package is there to showcase vehicles with ChaosPhysics and stuff, I guess it wa smean to be a standalone version

[lusty hedge]

but the hit is indeed happenign

because the trace turns green

[frosty heron]

U tested it?

[lusty hedge]

yep

[frosty heron]

Print string hit comp

[lusty hedge]

ok

nothign

[frosty heron]

So wat is that on hit for event for then?

Well that's Ur issue if u got nothing

Make sure the comp is hit by the trace

[lusty hedge]

it is

the trace is hitting the comp

100%

[frosty heron]

Well when u trace did it print your comp?

[lusty hedge]

no

[frosty heron]

Get hit comp -> print

[lusty hedge]

i need to print from the hitboxes BP not the trace

so the thing getting hit needs to print

not the thing hitting

[frosty heron]

Well make sure the trace actually hit the hit boxes bp component

[brazen pike]

aren't hit events physics only

traces are query

[lusty hedge]

it turns green for a hit so im sure its hitting the component

[brazen pike]

it's hitting the component, but the component likely doesn't realise yet

If it isn't triggering hit events, then you've got your answer

[lusty hedge]

is it something to do with this

[frosty heron]

Maybe check detail panel and tick generate hit or something like that

[lusty hedge]

i dont understand your point

[frosty heron]

If there is one

[brazen pike]

I dont think either ColdSummer or I know the answer, is what I'm trying to say

[lusty hedge]

oh

[frosty heron]

I declared to be guessing at the start

Never done anything like that

[lusty hedge]

in this case. what does block trigger

[brazen pike]

Yeah why are you doing this? Is this for testing or a mechanic

[lusty hedge]

i have a vehicle

that is recieving a hit from a trace

i want it to take damage

[frosty heron]

Doesn't seems to relate to trace but I dunnoe

[lusty hedge]

when hit

[brazen pike]

Okay, flip this around

typically when you are handling a damage system using traces you will do all the code on the trace's side

You will cast out a trace, the trace will hit something and whatever casted the trace will decided if the thing the trace hit is something we want to damage. If it is, then "apply damage"

You wouldn't do it the other way around because not every linetrace is going to be a "damage" trace. Sometimes you might just want to check if something is there. Therefore, it's best to let the trace decide what to do

[lusty hedge]

I could do it that way and i just might

but i wanted the tank to recieve the trace

oh well

[frosty heron]

You can probably call function or use interface?

If hit actor implement interface, call function interface and pass the hit data

Just a thought

[lusty hedge]

the trace could be hitting 100 diffrerent things

then i have to do a check for everything in the trace BP

[brazen pike]

This is not as bad as it sounds

[frosty heron]

Only the one that implements the interface

[lusty hedge]

interfaces

ahhhh

lovely

im a noob i might need help with that but ill try first

[twin shale]

I have some spline points that are made programatically. I set their Point Type to Curve, but the tangents do not appear to update. What's the correct way to get these to automatically update their tangents?

[brazen pike]

There are dozens of tutorials on youtube about interfaces

[lusty hedge]

yeah ive watched many they confuse me a bit

[frosty heron]

Especially for damage imo

You want to damage a tank and a barrel

Each can implement damage differently

[lusty hedge]

so bullet travels. boom hit. the bullet calls the interface.

and the tank implements that interface

[hidden cedar]

I am not sure where to ask this, but does anyone know how to make a camera bop and weapon bop like in forgive me father? (https://www.youtube.com/watch?v=3W39GAEFnIk) It's a great boomer shooter, I am currently making something similar as a private project, and I'm not really familiar with the camera and timelines. I love the movement in this game, and I can't seem to figure out how to replicate it or make something similar.

(I also have sprites instead of 3d models for the weapons and enemies

[lusty hedge]

thanks

[lusty hedge]

ill give it a shot

[frosty heron]

It was confusing for me at the start but once you understand and practice. Interface is very straight forward

[lusty hedge]

okay i think i nearly got it

[brazen pike]

You can use a camera shake for the camera bob. But the weapon bob is much harder. A lot of people use animations for weapon bobbing but you can also do it programmatically if you dont have animations for it. It'll involve constantly updating the gun's relative position while you are moving.

[lusty hedge]

this is in the trace

thats the tank

[brazen pike]

"apply damage" is already a thing thats set up for you

But if you want only specific actors to be damaged, then this is perfect

[lusty hedge]

i need to make my own

the tank has multiple hitboxes

different damage types

all g

[undone bluff]

unreal handles damage types

[brazen pike]

All of these are features in unreal damage handling

[frosty heron]

But it's as old as dinosaurus

I never used it my self but I know it's actually borderline deprecated

And just straight abbandoned

[brazen pike]

is it? first i've heard of it

[frosty heron]

That's what I heard from other

We getting upgrades to old system

Mover 2.0 in 5.4

[tardy ridge]

Yeah, it "works" for ultra simple health points basically, but it's not something they are adding to. you can think of it as "complete"..in a way but mostly an old way.

[lusty hedge]

altho its nice to have unreal have built in stuff. i like to make my own functions in this case

id rather not have empty pins i dont use in a function

when my system is so much more simple

its just passing floats

[hidden yacht]

Thank you guys for the advice on local vs server input system implementation. I am still trying things out, haven't tested it fully.
Out of curiosity I did the following in my ThirdPersonCharacter BP file

based on this , The pawn exists on both server and clients

so I'd expect the chain to run twice, on the srver and on the client ( I have 1 client only in editor )

[tawdry walrus]

how to spawn widget inside another widget using Blueprint?

[frosty heron]

AcknowledgePossesion is a function in player controller that is called by the server on clients.

Adding a custom event here not gonna do anything

[hidden yacht]

since the POSSESS is server only, i'd the nexpect it to run only once, the client side won't run it

[frosty heron]

Try what's suggested earlier

[hidden yacht]

well, it runs twice on the server

look at the this

[frosty heron]

Lemon is telling you to call a client rpc On posses

[undone bluff]

you seem to have accidentally sent this into chat instead of google search

[frosty heron]

This still run on server only

[hidden yacht]

check the logs

[frosty heron]

Yea nothing suprising

U are creating a custom event, not overriding acknowledge possession

[hidden yacht]

there is nothing such as acknowledge possession in nodes through BPs

in nodes list

[frosty heron]

K then do the other way like suggested by lemon

I kinda list the steps too

[tawdry walrus]

yeah, I was looking to another monitor

[undone bluff]

happens to the best of us

[frosty heron]

@hidden yacht #blueprint message

[little moat]

Should this work?

It's not setting the default pawn

[hidden yacht]

for now i'm not trying to make movement work with vehicles ,just print something on successfull RPC server > client

[frosty heron]

But why? Just override from the level

[frosty heron]

Still the same suggestion

#blueprint message

[hidden yacht]

that's what i did with custom events

[frosty heron]

Don't forget the rpc

[little moat]

Wait what?? How

[hidden yacht]

replicates : run on owning client

[frosty heron]

In the level you are in. Go to the world setting

[brazen pike]

you need to make it an RPC. RPCs will execute on different versions of the game. Click on your custom event and set replicates to "run on owning client" and tick "reliable"

[frosty heron]

You can override default pawn class there

[little moat]

I thought it overrides the whole game

[frosty heron]

No you can override on per level basis

Don't set it in your game mode class, override from the level you are in

[little moat]

I spent so much time trying to have a different pawn in my level and then I didn't realize I could do this

[lusty hedge]

One more thing !!! i have it working. but the tank has multiple hitboxes. is this a good solution?

i mean it works

[little moat]

Thanks a lot, people over in #cpp couldn't figure that out

[lusty hedge]

is there a way to do multiple branches like this in 1 node

so it looks pretty

[frosty heron]

I'm sure they know about it 🐈

[hidden yacht]

I did two tests, one with replicate to owning client and the other with DONT replicate.
I started with RPC on owning client, then the logs showed the print twice , so I changed to DO NOT REPLICATE, was still printing twice, i screenshoted the last one only and came here to clear the confusion

[frosty heron]

Can't tell what u r doing but you can use select node

[hidden yacht]

lemme try again with RPC

[frosty heron]

Instead endless if statement depending on what u doing

[frosty heron]

Remember that the code runs on every character in the world

Don't know what u r doing atm but if you want to filter out stuff in client machine to just run the code in the character they own. You can use is locally controlled

[compact sandal]

i sent this last night and still haven't gotten an answer, can someone help please?

[frosty heron]

I don't even know what I'm looking at 🤣
@compact sandal

[brazen pike]

that looks like a hardware issue to me

[hidden yacht]

the double execution means the pawn is being possessed twice since start of game ?

[compact sandal]

i dont either 😭, it happens when i debug draw any form of line

[compact sandal]

what could it be?

it goes away right after the line disappears

[frosty heron]

You have 2 characters in the world. The server will print once for each

What's the point of is server here?

[hidden yacht]

I only have one client

[frosty heron]

On posses already called by server only

U r on listen server?

I'm sure there are 2 players

[hidden yacht]

just understanding things on my side

[brazen pike]

the graphics card probably

[frosty heron]

The is server on on posses is redundant.

[compact sandal]

well that's scary

[brazen pike]

not necessarily. if you look on forums other people have this issue too

[frosty heron]

Ahh ok

[silk cosmos]

Are your drivers up to date? I would start there

[compact sandal]

im updating them now

I mean , i get you, on possess is server only, but you know, i'm inserting nodes and expecting things to be a certain way, in this case it should indeed be server only and not print IS CLIENT CALL

[frosty heron]

Ye I don't mean to say don't experiment. Just explaining that it's redundant in case u didn't know

[hidden yacht]

Thanks, appreciate it 😄

[frosty heron]

I am not aware why it's printing twice tho

[brazen pike]

For now, put a "Do Once" on possess

[hidden yacht]

what my understanding is, as long as the starting node of the chain is server only, whatever comes after will be server only till the chain is over ( chain is linked with the exec white lines )

[brazen pike]

then connect "Unpossess" to the reset pin

[onyx token]

am i being dumb

why is this output an integer

i'm dividing it by 10.

i just wanna have 1 neat node that converts it to m from cm and rounds it to 1 digit after the comma

[frosty heron]

Isn't there format for numbers

I mean I used it just can't remember the node

[brazen pike]

thats converting to text

[hidden yacht]

I am having a possession and unpossession then a repossession, wtf is going on lol

[frosty heron]

Ahh right

Also never touched math expression. Gl

[onyx token]

screw it.
I'll follow your example, not touch it and-

[frosty heron]

Don't be me

[hidden yacht]

lemme show you how i spawn the player

[frosty heron]

I'm dumb

Keep moving forward

[frosty heron]

Not using player start?

[onyx token]

its too late.

[hidden yacht]

this is on game mode

as a function

[brazen pike]

@hidden yacht Show the "Pawn" section of the details panel for your character?

[hidden yacht]

not using the default pawn, i'm spawning it manually

[frosty heron]

Bruv I reckon you are spawning by game mode

But then u have Ur own spawn logic

Which kill currently controlled pawn

Then spawn and posses again

[hidden yacht]

why is there a current pawn at all at start to be killed

since i dont set the default one

[brazen pike]

it uses the project default if you dont set one

[hidden yacht]

where is that set ?

[frosty heron]

Check your world settings

[steady night]

hey

[hidden yacht]

Bingo, and my bad, for some reason the default was there again

i'll clear it

[frosty heron]

That explain the double print

[steady night]

Coldsummer

i need you again >)

[frosty heron]

3.27 am

[steady night]

what really

ok but this is easyu

[brazen pike]

yo me too

[hidden yacht]

x1 print ! Yeey ! Thank you 😄

[frosty heron]

Western Aus brother?

[brazen pike]

yeah perth

[steady night]

im trying to linetrace in an circle like how im spawning the effect

[frosty heron]

Same2

[brazen pike]

hell yeah

[steady night]

ok its fine you go sleepsleep ill solve it np 🙂

[frosty heron]

Probably want to look at some math if u gonna do bullet hell and all that

[steady night]

yeah

[frosty heron]

Dot product, vector math etc.

I'm gonna touch them eventually

[steady night]

hehe

[frosty heron]

Gl man

@brazen pike see you around m8

[brazen pike]

have a good one

[hidden yacht]

aaand we're driving 😄

The working solution

Just making sure of the concept here,
the RPC on owning client will never be expected to run the isServer true branch, right ?

as long as it is set to "owning client" !?

@frosty heron

just as the redundant part on server side, can we say that this is also redundant ? will always run as client on that branch ?

[brazen pike]

Yes

Unless you are running it on "listen server" but you are doing "client" right now

and even then, you can assume it will only be client honestly and be fine

[hidden yacht]

Thanks !

[faint pasture]

Anyone here ever dealt with root motion OUTSIDE of the Character?

[noble ledge]

If I have two versions of the same project, whats the easiest way to find the changes to the newest version?

[faint pasture]

Some sort of diff tool

are you not using source control?

[noble ledge]

No

I seen that I can diff two blueprints, but that would involve merging both projects and then diffing each one

[faint pasture]

You should be using source control

Initialize it as one of the versions, then overwrite with the 2nd, then you can diff and see all the differences

[noble ledge]

Would Git be fine or should I look into something else?

[opal pulsar]

you should start by having a variable that stores your "fear level" somewhere
it probably makes sense to have it in the player

then you can just add/remove to that variable whenever and however you want, as long as you have a reference to it, and just check if its maxed out every time you change its value
instead of checking every time however, you could probably just have a custom event in the player that modifies the fear by an iinput amount and then checks whether its maxed out or not

[lofty rapids]

i like to keep things in game instance

it persists

pretty much globals

you need to have a level of fear like variable maybe a float or integer ?

so you can check what it is and act accordingly

for the ui you probably just want a bar ?

your fear amount

it's two different parts your data and your display

some like fear and maxfear might work

same way you do health

where you can just divide them to get the percentage to display

[shut yew]

PlayAnimMontage not working

[lofty rapids]

i usually keep different functions, one for updating the value, one for display

and just run them whenever i update a value

[shut yew]

skeletal mesh not ccompatible with character obj referrence

[lofty rapids]

you can use the one when you update the value of fear to check if it's at max

or even the display one either or

[shut yew]

its in a function in bp_thirdpersoncharacter

[lofty rapids]

you have a slot in your animation bp ?

[shut yew]

huh? sorry what?

lemme research about that

[lofty rapids]

you need to add a slot to play a montage

just add a default slot

should be all set

[shut yew]

na

where thoi

tho

[lofty rapids]

in your animation bp

[lofty rapids]

goto your character, loop for animation class

then find that

and open that

[shut yew]

this?

[lofty rapids]

ya

that class

maybe it has a slot

it should if it's prebuilt one ?

but look at that animation bp and see if it has a slot

my guess is this is a template ? so it should have it

[shut yew]

nah it not

its made by me

[lofty rapids]

oh ok

[shut yew]

animation montage

[lofty rapids]

so what does the animgraph look like ?

thats where you add the slot

[lofty rapids]

if you made it how come you can't open it ?

you know where you put it ?

it's the class that is your animation

[lofty rapids]

search for that in the content browser

those are not it

[shut yew]

nah thats the only thing i did

i made a sequence imported idle and rigged it a bit

and then i baked

and done

[lofty rapids]

hmm

i know you need a slot

i don't know what kind of animation setup is going on

and like mentioned make sure your target is correct

[shut yew]

cant really set the target

[lofty rapids]

play anim montage

not play animation

[compact sandal]

well i updated both unreal and my drivers, it still appears

[shut yew]

worked

my anim montage was busted

[shut yew]

thanks

[lofty rapids]

what does it say ?

[compact sandal]

it says

well it says this

[lofty rapids]

where does it display that when you run it ?

[compact sandal]

it shifts everything to the side and puts that on the right

[lofty rapids]

looks like some sort of option or extra window

weird

[compact sandal]

it's whenever i draw a line trace

[compact sandal]

but if i put a blur effect through the level blueprint, it blurs the weird thing as well

watch

[lofty rapids]

you might get better answers in a different section like #ue5-general , or another one idk

not really a blueprint problem

[compact sandal]

ur right

[lofty rapids]

i feal like theres some sort of setting for this it looks like debug stuff

[compact sandal]

lemme do that

[compact sandal]

i know and i thought that too, but i looked in the stats thing on the upper left menu with the fps things and nothing was on

very strange

let me

post this in #ue5-general

[lofty rapids]

they might be able to atleast send you to the right section or have a better idea

[tough siren]

Hello, I am working on a project but there is a subject that I do not understand. The server should select a random map and send all the players in the lobby to the selected map, but I couldn't do it. For example: Random map in Pummel Party, random map in Fall guys, random map in Crab game. How can I do this random map job?

[chilly plover]

How would I move an object along a line?

[lunar sleet]

Make it follow a spline

[lofty rapids]

idk about sending to the correct map, but by map do you mean level ?

[tough siren]

Yeah

[novel swan]

There must be a better way to do this in blueprints?

[dark drum]

What are you trying to do?

[novel swan]

Well check what type of actor it hit so it can take the appropriate action. More specifically this is the blueprint for a projectile and once it hits something I want to apply damage to the actor or some other logic depending on the type of actor it hits eventually i do want this to be an online multiplayer game and so if this is poor design for online multiplayer please let me know.

[dark drum]

The projectile shouldn't really care what it hits. Just call apply damage on the hit actor. The hit actor would then decide what happens using the on damage received event.

[novel swan]

That's interesting but in doing so I assume that actors even those that can't be damaged wont throw some error when i try to apply damage to them

[dark drum]

If an actor doesn't handle the damage using the on damaged received event, nothing will happen.

[novel swan]

Alright thank you so much. Just cleaned up my code and understanding a lot

[chrome crag]

Hey all im using a level sequencer to hide then spawn enemies after I talk to an NPC. But when I unhide the enemy BP it wont move in the nav mehs...any thoughts? (i have already made the auto posses 'placed in world, or spawn")

[steady night]

hm this linetrace is endless :/ Why ?

vector incoming is from a impact point

[dawn gazelle]

Are you incrementing Last Index somewhere in the loop?

[steady night]

no

[dawn gazelle]

Or do you mean endless as it goes out to infinity? 😛

[steady night]

yeah

[lament shoal]

hello everyone, I'm having trouble understanding the relationship between Skeletal Mesh and Control Rig when it comes to blueprint programming... or maybe I am misunderstanding something even more fundamental, this should be trivially easy but I am tripping up hard, hope someone can help...

I am looping through an array to do some tracing - I can either loop through the skeletal meshes which have one control rig component mapped to them, or I can loop through the array of control rigs, which each have a skeletal mesh mapped to them. In either case, I need access to the proper object reference (but **not **the Scene Component Object Reference I get by calling Get Parent or Get Child, rather I need the Control Rig or SM reference) - for example, I want the Skeletal Mesh Component Object Reference of a Control Rig's mapped SM to feed to a Get Bone Transform but somehow I cannot get it.

[dawn gazelle]

You probably want to take the rotated vector and normalize it then multiply it and add it to the original vector.

Right now it would be rotating a value that could be large, like (1000, 0, 0), you're rotating it on Z, so then it could end up being like (999, 1, 0), then multiplying it by 500 which would result in (499500, 500, 0) and adding that to your vector.

[steady night]

hhmm

yupp

that did it

awesume

[mild ibex]

For level instances, im not entirely sure why it wont dissapear, I've tried a lot of dfiferent things but supposedly this is supposed to work. TLDR is that a user is presented a list of levels that do have to be mapped to ints because I'm using an application outside of UE that obviously cant send levels in, and even sending by name is not what I want, but user picks a level and it should load, hiding every other level. I wanted to see if I could unload level and just get rid of it entirely but that doesnt seem to work either?

It does load the correct level every time it just refuses to unload the levels

[faint pasture]

Tick -> look at where you are -> calculate where you wanna be -> move there

[lofty rapids]

are you loading all of them ? and setting them to remove after if they are not a certain one ?

because why not just load the one you want

[mild ibex]

yes, mostly because I dont understand how to actually unload them, because the false logic of the branch appears to straight up not work

because what should happen is on start it loads the default level, which happens as expected, then i select a different level and it should hide / unload that initial level and show the selected level, which doesnt happen at all, it just shows both

[lofty rapids]

you should have something thats a reference to the current level somehow

so you can just remove the one thats loaded

and then find a way to load just the one

if you have a lot of levels that loop approach is going to be a pain

[mild ibex]

right, I have tried that as well but my continual problem seems to be unloading, I can try a few more things but should what im doing already be working?

[lofty rapids]

idk how to unload level instance i still have a lot to learn

i've only loaded by name

[mild ibex]

its basically the same thing as far as im aware

[lofty rapids]

right but when you load by name i believe it just unloads the other level

atleast that's what i assumed

it goes away

[mild ibex]

i assume you have the levels part of the persistent already?

[lofty rapids]

"part of the persistent" ?

one of my projects has levels i load by name

idk if it keeps the others in memory but i wouldn't think so

[mild ibex]

yea like the levels window has persistent then a bunch of other levels underneath, if not thats fine

[feral marten]

how can i get this to not error? the function doesn't modify state, it just gets the positions to draw the branch. here's the error:
Function Get Branch Draw Points can modify state and cannot be called on 'self' because it is a read-only Target in this context

[proper vigil]

Any ideas?

[dawn gazelle]

I think that's a custom function? If you haven't already, open the function up and go into its advance settings and click "Const" that should fix it.

[feral marten]

yeah it's a custom function in a basic blueprint class

setting the function to const didnt seem to work

nevermind it did, i just switched the wrong function to const lol

thanks

[sand spoke]

Is this a smart design?

[faint pasture]

What....... are you trying to do here?

That function doesn't do any casting so why is it named like that?

[sand spoke]

This function is to get an actor without having to have an exec pin

[faint pasture]

why though? What does this buy you?

and why the index?

[sand spoke]

Index is for the get from the array

[faint pasture]

But how would the caller know what index to pass in?

[sand spoke]

When I use the function I input the index

[faint pasture]

At least call this thing GetFirstActorOfClass or something

it's not doing any casting

[faint pasture]

Where do you get the index from?

[sand spoke]

From inputs

[faint pasture]

I mean in practice. Where does the caller get the index from? What are you actually attempting to do here? I could MAYBE see a use for it if you used GetActorOfClass and it just returned the first one it found

btw you'll have to cast the returned actor ref anyway

unless you just want to have it as Actor

[novel swan]

I'm trying to understand why is it that when I set my root component to my collision (capsule) then my projectile hit events work normally but when I make the Static mesh the root component then it doesn't work at all and my projectiles simply go through everything.

[brazen pike]

the root needs to have all the collisions set up

[novel swan]

That's like a rule? That's always the case?

[brazen pike]

I believe so

[novel swan]

I hate that lol. Not that I've read all the documentation or anything but I haven't seen that explicitly stated anywhere. If anyone has more information please I'd like to know more otherwise I'll just make sure my roots are my collision components going forward.

[brazen pike]

This is just something I've had a problem with before. My projectile was only fixed by moving my colliding component to be the root

if there is a scene component, for instance, as the root then it wont work

[novel swan]

yeah that's what I've noticed now too

[lusty root]

I have a spawner that keeps all the spawned objects in an array. I would like to destroy an actor by the array index but all I can find is Remove Index, which removes the array entry (shortening the Length of the array) and leaves the actor in the scene.

[novel swan]

Can you do this?

[lusty root]

Yeah I think Get is what I want to use here. I was confused because in the drop down it says Get (A Copy)

[eternal totem]

Does anyone know if I can access the face or vertex data of a specified material ID on a static mesh? Say I have a square with a blue material and on the top face it has a yellow material, can I get that second material and find where the face or verts are in world space?

[main lake]

You should use "Interfaces" and have a method in it called "OnDamaged", and OnComponentHit you check if the actor implements your interface, if yes then call the "OnDamaged" method 🙂

[lusty root]

Thanks LightMatches, using Get and fixing an off-by-one error and I'm in good shape now.

[chilly plover]

Guys any idea why this slot keeps failing? The file exists

[main lake]

Try to print the return value of your "Load Game From Slot"

[chilly plover]

How do I do that?

[frosty heron]

It gets a copy of pointer

Still pointing to the same thing

[lusty root]

Thanks, that makes more sense. 🙂

[main lake]

You use the "Print String" node between your nade "Load Game From Slot" and "Cast To BP_SaveData_PlayerData" and drag a line from the "Return value" of "Load Game from Slot" to your print string input

[ocean crow]

is there a way i can get a reference to the static mesh of an actor without it being of a specific blueprint, just the general "Actor" class?

[frosty heron]

no because an actor alone doesn't contain static mesh

what you are doing doesn't make sense

you can cast it to your BP base Item Pick up then plug it to the static mesh

[ocean crow]

should i cast to the specific BP and then yeah ok ty lol

[frosty heron]

Possible scenarios
-Save file doesn't exist and return value from LoadGameFromSlot is Null
-The return value from LoadGameFromSlot is not derived from BP_SaveData_PlayerData

[trim matrix]

Like all those actions are greyed out in the context menu, and hotkeys for them don't work either.

[frosty heron]

My first project doesn't have any composition, my player BP is huge like a mountain. Had to restart every 8 minutes, working on it is a pain.
Every 8 minutes, my right click just stop working, it will show context for 1 frame then it just disappear.

[hollow cove]

I would also like to know why this happens to me. only happens for me like once every other day though.

[gentle urchin]

Could it be related to focus or window drag focus?

One of the bugs i get is when i just started the editor. Where stuff simply isnt clickable. Tabbing out and back to editor makes it work again

A other one ive seen is that it gets stuck during a drag operation

Where you get this highlight with some wireframe over an area. Solved by just dragging and cancelling a new drag operation

[trim matrix]

Hey guys, why my SweepResult from OnCapsuleOverlap always have Location, ImpactPoint, Normal, ImpactNormal equal 0?

[marsh gulch]

I keep on getting this error, I already tried adding an is valid? To possibly fix it but the same error message keeps popping up
Anyone any idea how to fix it? @ me would be appreciated

[trim matrix]

could be you are casting a nullptr

[marsh gulch]

Prob, but no idea how I fix it though, I'm not that smart

[trim matrix]

Is Valid before cast lul?

[marsh gulch]

How do I check that?

[trim matrix]

drag the "Pawn" out and type "Is Valid"

I am not sure you and i are on the same page

[gentle urchin]

Cast includes isvalid

[marsh gulch]

I am reallly new to all this so I don't know a lot at all sorry
Did you mean something like this?

[gentle urchin]

If its invalid, cast fails. If its the wrong type, cast fails.

If its valid and correct type, cast succeed

[trim matrix]

yeah i think that's true

[marsh gulch]

Well I get the same errormessage regardless of checking with is valid? Or not

[prisma walrus]

Hi all, wondering if anyone can help with what I hope is a simple issue https://forums.unrealengine.com/t/crt-vcr-how-do-i-use-a-trigger-to-play-a-custom-movie/1673640/2

[trim matrix]

the original code should be working

Even when I remove the is valid command I still get the same error

[gentle urchin]

Also you can prob just cast to character

If all ypu need is access to cmc
