Check your trace channel and the component collision that you are tracing againts

When you break down the hit result you can get the hit component

[lusty hedge]

it turns out i did not know how collisions work at all

i think i figured it out

i did this for the hitboxes

and this for the decals

so the ray only hits the custom hitboxes and not all the objects around the tank

if you're curious

[pine mesa]

nevermind it works now, I used a "Montage" node instead of using the "Animation Montage" node.

[sour moat]

Hello, the armor and character have same skeleton but the armor mesh doesn't attach to character mesh perfectly, how to fix that? 😐

[vital cargo]

Is there anyway to detect a gamepad (XBox controller in this case) through BP?

[midnight arch]

Hey, this might be a dumb question, but I was following this tutorial: https://youtu.be/gsWHj8GbsfM, and after getting through all of it I realized that at what he does at 3:05 should probably not be done in BP_FirstPersonCharacter and rather in BP_FirstPersonCharacterController (Correct me if I'm wrong) since the tutorial is for UE 4 and I'm trying to follow in UE5, I would really like some help on how to call ParkourMovement (which is in BP_FirstPersonCharacter) from BP_FirstPersonCharacterController in order to follow the guide correctly (if you have a different way to do this please do let me know)

[acoustic lance]

I'm struggling to figure out how to incorporate z axis movement into my first person bp for when in a water physics volume. Or one of the water zones or whatever. Is there a good tutorial for this kinda thing? I've seen several for 4.26 or older, but I'm in 5.x and the nodes seem to be different

[lunar sleet]

What made you think that should be done in the PC instead of the char?

Either way if you want to access something inside the player char, drag from that get player char return value, cast to your char bp, and get the component from the cast return value. And at some point, watch the bp comms live training video at the bottom of this channel’s pins, so you understand how casting actually works @midnight arch

[lunar sleet]

It’s unlikely you would find a tutorial for anything that specific but Google is your friend

[runic coyote]

#animation message not sure if my problem is BP or anim related.. I’d appreciate some advice. Thank you

[midnight arch]

First off, sorry I made that mistake, it just seemed right since firstpersonchar didn’t have the event begin play and the first personcharcontroller did, I am only 2 days into learning unreal and the bp structure is still very hazy to understand, second off, thank you so much for you help and I will try my best to implement this to hopefully fix my issue 🙏🏻

[lunar sleet]

I didn’t say it was a mistake, I was just asking what made you get to that conclusion

[midnight arch]

Oh my bad

[lunar sleet]

Also just fyi most bps you work with will have a begin play event. It might not always show but you can right click and search for it

[midnight arch]

But yeah, like I said when I go into the default template bp_fpchar it doesn’t have the event begin play which is what he goes off of in his tutorial, and when I brought one in, it broke the controller, so I assumed it was now meant to be initialized in controller rather than char

[lunar sleet]

Nah, the reason the controller has one already is because Epic is adding the mapping context to the controller in the template

The latter is how you make input work

But def should watch that bp comms video when you have the time. I didn’t really understand casting or interfaces until I did

[midnight arch]

Just found it, I will definitely make watching in full a priority. Thank you so much for the help, trying to figure this one difference from the tutorial has been the biggest headache so hopefully your advice + the video can get it all sorted, thanks again 🙏🏻

[lunar sleet]

That’ll be #animation I think. Rotating bones can be tricky, as they can influence each other and have rotation limits applied by other bones due to weight painting

[frosty heron]

Do a multi ray cast? It will return all the component as long it can be hit (collision setting)

[dusk saddle]

Hey everyone, I am a bit new to this whole thing in blueprints and im trying to learn about interfaces
I want to pass a boolean variable to another blueprint (the level blueprint)
and I cannot really figure it out
If anyone has any recommendations it would be appreciated

Thanks.

[lunar sleet]

Scroll to the bottom of the pinned links here, there’s an Epic video that goes over casts, dispatchers and interfaces

Bp comms live training

[dusk saddle]

i will look

thank you

[lunar sleet]

Having said that, I don’t believe you can talk to the level blueprint, and you shouldn’t be using it except for very rare circumstances. Videos that teach that are outdated

You can use easily accessible things like the player controller or game mode instead

[shy gorge]

You need to send message of that "New function" not call it.

[lunar sleet]

You need a ref to the target to message something

You can’t ref the level afaik

Not as a way to talk to it anyway

[dusk saddle]

yeah i tried LOL

okay let me try something

[shy gorge]

oh missed the level bp, morning eyes

[dusk saddle]

lol

[lunar sleet]

Use the player controller bp

[steady night]

my launch character only works in Z direction dosent launch any other ways

:/ ? anyone know what this could be related to ?

[alpine kettle]

Quick question: I would like to record my Motion Capture movement during runtime (built version) and replay it immediately. Basically recording it and immediately showing the animation after. Does anyone know if this is possible or even has an example where to look at? Thanks! ❤️

[shy gorge]

take the XY override off

[steady night]

did

[shy gorge]

what is your roll power value

[steady night]

1000

https://gyazo.com/2f0efd909b546bceefd52de84382adb9

its not affecting X,Y for some reson ??

[shy gorge]

that should work

you have something else somewhere blocking the movement, for my testing it should launch pretty high with those values anyways

[steady night]

yeah..

what could be blocking the movement ://

i have no clue

[covert hull]

Is someone down to help me with 3d widgets for a game called dead by daylight, please, if Yes i would be very thankful

[steady night]

?

wtf

copyrightt bro

[spark steppe]

i'll make a game named "Dad by Daylight" where you have to survival in the world of capitalism to feed your family

[steady night]

lawl

Ben your good at this stuff

what could be blocking m characters so launch character dosent work i directions >.>

only up & down

[spark steppe]

https://tenor.com/view/elmo-shrug-i-dont-know-gif-14777043

[steady night]

exactly

never happend to me b4

the launch is affecting the characters "capsule Component" right ?

or what is it acctually using

[thin panther]

No. For starters check the #rules on crossposting, and secondly the game doesn't officially support modding, so check the #rules on underground modding.

[covert hull]

Actually i mod the Offline version of the game

[thin panther]

It doesn't matter, it's still underground modding

[covert hull]

Bruh

[lunar sleet]

Against the #rules and not up for discussion

[covert hull]

Didnt expect this to be such lol

Ill try to find someone who can help me in dms

[thin panther]

Randomly dming people is also against the #rules

You really ought to read them

[delicate gazelle]

hello, sorry for pinging you, but I was wondering if you found a solution to the spline disappearing? I'm having the exact same issue and it's driving me nuts

[keen widget]

guys, how to replicate varible but when client joined after server already changed it?
how to make client request current varible state from server?

[frosty heron]

@runic coyote if you set the variable to replicate then ilthe client variable will eventually be sync with the server

If you need something to happend when a variable gets updated (server reached client to do an update on the variable) you can use repnotify

You should read the pinned articles in #multiplayer it will answer most of the thing you need for replication

Replication and server rpc is the easy part in multiplayer. Depending on what you want to do, be ready for a world or pain.

[exotic moat]

Someone please help me, surely im not this stupid why is this not working. All of a sudden i cant do set array elem anymore

[frosty heron]

Index 0 or 1?

U set array element on index 1 but reading index 0

[exotic moat]

yeah ignore that bit

even when its set to 1 it still doesn't print anything

[frosty heron]

Then row is not found

Debug that too

Print string on row not found

[exotic moat]

yeah it finds the row

[frosty heron]

Then print string

[exotic moat]

i think my array might be corrupt, the array itself is meant to be 24 in length however when i click size to fit and then print the array length it says 2

[frosty heron]

Also cant debug on your end, and it would be more difficult if u don't show that u are actually finding the row

Afaik blueprint array is dynamic anyway

[vast stream]

Maybe call Resize on Inventory Array first before calling Set Array Elem?

[frosty heron]

Print string if row is found, print string if the outrow is valid. Then update array then print the actual index you update

[exotic moat]

Nope im just an idiot

had a function load the array from game instance. The game instance version is only at a length of 2

[frosty heron]

Length of 2 means u have index 0 and 1

Oh well so long it's fixed

[steady night]

Do anyone have any tips Why my Launch Character dosent push sidesways only upwards (all the launche options is working tried on a new Charcter) but something must be blocking it somehow any one have ideas if there is any settings or so ?

[runic coyote]

Problem is this happens only local client :/

[runic coyote]

Not even in multiplayer or an online setting and it happens

[runic coyote]

Thanks for the tip on weight painting

[kind estuary]

This is 1.8GB

does this impact performance?

Should i use interfaces for everything

i think this is because im referencing everything

The game has good performance though

[thin panther]

That's the disk space

[kind estuary]

But i just use references and casts as much as i want like a dummy

[thin panther]

Use each when you should. Never go blind one way or the other

[kind estuary]

actually memory size is even worse

[thin panther]

There is little reason a floor tile should depend on all that

[kind estuary]

I saw in a tut they said to always use interfaces

and if you reference you end up with stuff like this

[thin panther]

The tut was stupid

Don't listen to it

Use both when they have their strengths

[kind estuary]

So thats not bad?

1.9 GB?

[thin panther]

No that is bad

You've abused things there

Cast to base classes when needs be, and make sure soft references are used for things that don't need a specific world instance.

Use interfaces when you want class agnostic behaviour or to decouple code

[frosty heron]

Server rpc is the only way to communicate from server to client. If you change something locally then it will not update on server unless u run a server rpc.

Read #multiplayer pins you will need it

[frosty heron]

They don't know any better

While it's true casting everywhere in bp will load a lot of stuff . Interface is not a **** solution

[runic coyote]

Okay I shouldn’t have had a replicated variable in my screenshot because this issue isn’t related to server execution. My issue happens on a standalone client without server calls and that variable is not double set due to my rpc architecture

[frosty heron]

Interface is used when you want to communicate between different classes

Using that to avoid hard ref, you will have a project that's really hard to debug bot to mention most of the time ppl fall back to hard ref anyway even in their interface

Casting is unavoidable. Cast to base class like cuppa said when possible. Then use soft ref to load all the heavy stuff

[frosty heron]

Not following you sorry

[thin panther]

And guess what tutorials teach! Absolutely none of that! 🥳

[frosty heron]

My first project is an absolute mess 😰. Had to unlearn a lot of things on my latest project

[thin panther]

Same

[kind estuary]

So like for classes where you just need to cast and call a function in that actor, that doesnt use specifically that actor.
i have an actor that is called BP_ActorManager. And there i have functions that manage the actors.
So there i dont need a hard reference.

What if BP_ActorManager has a bunch of other references to the units themselves

like an Array of units

[thin panther]

But you do. You have a hard ref to the manager, and if that manager has hard refs to others, you depend on them too

For example if I need to call a function in my enemy, I don't need to cast to the class that has all the assets and everything. I just need a code only base class, which has the functions defined.

I don't mind so much if I depend on a few kilobytes of blueprints versus a few hundred megabytes of assets

If the thing I want to do applies to lots of base classes, I'd use an interface

If it's just something like spawning an actor, or holding a reference to an icon, or a mesh, then I'd use a soft reference

[kind estuary]

damn. the more i learn the more dumb i feel and aware i am of the mess i have been doing

[thin panther]

We all hit that stage :P

[kind estuary]

got it

thanks

[turbid pecan]

Hey is there a easy way to somehow mark maps using a boolean or something that can then be referenced inside a player blueprint and used to control stuff. Like say I have a "town" level, and a "dungeon" level, and I wanna make some special player behaviour based on whether the player is in some town level or a dungeon

Is there some linkage that I can achieve easily here?

[thin panther]

You can make use of gamemodes for this, and have a different player controller for your levels

[turbid pecan]

Hmm lemme check that

See I was kind of hoping to keep all my movement code inside the BP_FirstPersonCharacter file

And just drive it with booleans and branches

Like "if in town" move this way, "if in dungeon" move this way

Game mode seems to be a data only thing.. from the tooltip

I was hoping to make my "in town" boolean public and somehow store it in the construction script of the level

or something

[thin panther]

The logic is driven by the player controller which is set in the gamemode

[turbid pecan]

idk im a total newb.

[thin panther]

The game mode stores a player controller class.

In whatever level, use a Gamemode which has your special level specific player controller which uses your level specific logic

Driving it with booleans and branches is horrendously unscalable and inefficient

Use OOP, don't fight it

[turbid pecan]

Why would it be inefficient?

Im just trying to understand

Like ive got this setup atm

My thinking was that If I got the level BP to set "in town" based on whether the level is a town, i would need to do next to no changes anywhere and the controls would work just fine

[thin panther]

Because it's unscalable.
Each new level now needs a new Boolean, and a new branch in the spaghetti monster.

Rather than the intended method of driving level specific gameplay with level specific game modes that have level specific classes

[turbid pecan]

Why would it need a new branch?

[thin panther]

Because otherwise it isn't going to be checked if you're on a newly added level

Versus, again, just handling this stuff how you're supposed to

[turbid pecan]

Maybe I am not explaining well.

Any new level only has one little set of nodes: "on some creation/load event - set a public bool to either true or false"
Then when the player is loaded into the map, the FPChar BP just goes ok what does this public bool say? Oh ok we are in a town map, lets move side to side vs in four directions

But i am also taking on board what you are saying

Its just that I dont want a separate game mode per level

My levels can only be towns or dungeons

two types in the entire game

So they fit the boolean scenario perfectly

Unless I am missing something here

[thin panther]

They also fit the game mode thing perfectly

It's much easier to override a class in the world settings than to manage branch hell.

This is literally what game modes and player controller classes were built for

[turbid pecan]

Right, so in the game mode scenario, I should have two game modes, that refer to two distinct BP_FP_Character files each implementing it's own unique movement and then set any level thats a dungeon to use the dungeon game mode and town level to use town game mode?

Is that the idea?

[thin panther]

Ideally even you would use a player controller and avoid having two entirely different characters, but yes, generally.

You don't even need to make new subclasses of the game mode, the world settings have a game mode override

[turbid pecan]

So my choice to do movement nodes in the character and not player controller was not correct?

I kinda dumped that into the place where the FP template had its own movement nodes, which was the character bp not the controller

[thin panther]

It's personal choice, however for this specific case I would opt for the controller, so you're only swapping out a little bit.

The alternative would be having a base class, where you override the movement and only the movement in both

[turbid pecan]

I see

Okay, I am gonna dig into that a bit, see if I can grok how to do what you suggested

thanks

[thin panther]

No problem! Feel free to ask some more if you're stuck 🙂

[turbid pecan]

I... am always stuck. I just try to hold off until i can't unstuck myself through my own efforts. This was a confusing one for me.

Guess it's a very clear highlight of a lack of fundamentals

[thin panther]

It nearly always is :P

[turbid pecan]

Can I just ask another dumb q: I would be setting the "town movement" controller here, right?

So this is inside a town map. World settings > overriding the default game mode

I assume this is what you meant?

[thin panther]

Yep

[turbid pecan]

So I have cut and pasted my movement into the controller instead, however seems like only rotation works now. I lost my ability to move. I wonder if this is because playercontroller bp has different nodes for me to use to set location?

Ive got this

And I recreated all the necessary variables

compiled, all seems ok. But movement just wont happen

Could it be that the controller does not respect the IA stuff as a trigger? but then.. rotation would not work, which it does

[thin panther]

You'll want to set the actor location of your controlled pawn now instead

Currently you're trying to move the player controller actor

[turbid pecan]

oh

[turbid pecan]

yup this fixed it

Keep this up I will have to send you a case of wine or some shit

OK set it all up. Works like a charm. You are amazing.

[thin panther]

glad it works :)
Now it's super easy if you change your mind and have new level types, or want to do similar things across projects 🙂

[silent stag]

Hey , i have a simple objective system , i don't want it to appear when I start the game again, how can I save this bool variable?

[shy gorge]

https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/SaveGame/

[turbid pecan]

I wanna check an assumption with someone:

In a typical dungeon crawler fashion, as the player moves, they can trigger a random encounter which presents a fight. I kind of wanna go with something like - "you walk around, some pseudo RNG keeps rolling and once it triggers you set a fight state" which then transports the player into an "arena" where the fight takes place in turns. Now my assumption is that for this to be successful, I would have to store the location and orientation of the player pawn before swapping levels and going into the battle arena and restoring those after a victory?

Unless I have dungeon levels have a "off bounds" arena I can teleport the player to which might be easier

I guess from a bp PoV the latter would be easiest?

Not that the player could tell anyway?

[thin panther]

the latter is what most games do anyway

they're full of tricks like that.
For example, in Bethesda titles, instead of destroying enemy corpses that have been out for too long, and then figuring out if they need to do whatever on each load, Bethesda simply teleport them to a dead body room :P

[dusk saddle]

I hate to interrupt if I am but I am having a problem
"Blueprint Runtime Error: "Attempted to access TriggerBox_Blueprint_C_0 via property K2Node_DynamicCast_AsLight_Flicker, but TriggerBox_Blueprint_C_0 is not valid (pending kill or garbage)". Node: Test Graph: EventGraph Function: Execute Ubergraph Trigger Box Blueprint Blueprint: TriggerBox_Blueprint"

I have sent the event function to the other blueprint (kitchen light) and it still is not working.

oh wait

i think i know why

[shy gorge]

it is not valid as the error says 🙂

[void jewel]

I have a "sub level" variable that tells me which part of a level that is relevant, which I will then use to execute specific logic for that .

Does it make most sense to store this in Gamestate blueprint, rather than gamemode? so could i have a "level enum" in gamestate and then get that

[dusk saddle]

okay well now
I had the trigger box delete it self, but I stopped that action
and now its still not doing anything

[shy gorge]

what are you trying to do

[dusk saddle]

have it print string on another blueprint after the event sends the message

[thin panther]

you're only messaging yourself though

[shy gorge]

your message target is self so it is sending message call to the function on to itself

[dusk saddle]

OH

yeah still nothing, probably doing something wrong
lmfao

[thin panther]

watch the video on blueprint communication in the pins

You'll need to know how to reference actors.
you can't select a specific instance in the world like that, because the blueprint doesn't know what's in the world

[dusk saddle]

alright

thanks

[turbid pecan]

I just noticed I goofed a bit.. So when I load a level and select "world settings" and override the game mode using a controller, loading another level does not change those world settings so both levels end up using the same controller. I just noticed.

[void jewel]

any reason why i'm not able to get variables from gamemode? I'm casting to the correct gamemode which I know has this variable, but it doesn't show up

[eager thicket]

is there a universal blueprint that basically tells ALL active widgets to fade out?

or go hidden

[frosty heron]

U must have done something wrong because it's very straight forward to get variable from game mode.

You obviously need to make sure that the game mode is valid and it's what you are casting to. Start by proving if that's the case

[eager thicket]

Appreciate any advice here

[frosty heron]

You can get all widgets of class and set the vissibility

Not sure why u want to do that tho

[faint pasture]

They could all be held by some widget representing the entire UI and you can fade that

[faint pasture]

Can also try this if HUD is managing your widgets
https://docs.unrealengine.com/4.27/en-US/API/Runtime/Engine/GameFramework/AHUD/ShowHUD/

[eager thicket]

Hmm. This sounds like a feature i'll need to implement late into development

cus right now, all the widgets are pretty modular and seperate

[frosty heron]

Nice, I didnt know that one

[eager thicket]

Generally, it'd be to account of cutscenes/camera changes/etc

[void jewel]

yeah it should be extremely straight forward, this is never an issue. Here's a picture (left me trying to get the variable from casting that gamemode, from level bp). Right: the gamemode with that variable

[frosty heron]

I have bools for my widget that set its vissibility like bOnCinematic and bOnInventory etc

[eager thicket]

unironically a good idea i never thought of

damn it

this is why im an ape

[turbid pecan]

@thin panther i think I might have misunderstood how this works. I thought it was fine to have one game mode and then in the override for World settings it was enough to change the controller while in the open level that I wanted to use the controller for. Am I to assume that if I have two distinct ways to control the player, then I should have two game modes, each referencing their own controller and then set this in world settings? or..?

[frosty heron]

There is only one game mode, you don't even need this get actor of class node.

Simply call get game mode node

Print string the value and cast then print string. Show a picture of that instead

Also avoid level bp

[thin panther]

You don't need to.
When you switch level, the game mode, along with it's overrides are reinstantiated

except in some cases in C++

[void jewel]

ah of course lol. I'm able to get it now. Still find it a bit weird it wouldn't show up even if it's redundant to get it that way (?). anyway, thanks
maybe because it's not an actor that way?

[turbid pecan]

It does not seem to work this way. For instance, lemme show you.. Right now I loaded "DebugDungeon" level, and inside it's world settings panel I have:

But then When I load the DebugTown level, it had "BP_FirstPersonController_Town" set on that menu before, however now it shows as:

[thin panther]

You probably didn't save the level

once you override in a level it saves

unless, you're using level streaming and not hard travelling

[turbid pecan]

Well i am not doing any streaming. What I did was:

• File > Open Level > select dungeon > Open
• Set override to dungeon controller in world settings
• File > Save Level
• It asks (save controller too?) click yes

Then repeat with town but set "town controller" in world override, click save level and save controller

Reopen dungeon and the dungeon has town controller instead now

which is kinda confusing me

am i a total dumbass?

Would streaming be enabled automatically?

[thin panther]

you might actually need a game mode subclass then

[turbid pecan]

Seems like if i change, save the level and try to switch levels it does this:

So it's overriding it

sadly

[thin panther]

yeah seems that way. Odd behaviour but eh

make a subclass 🙂

[turbid pecan]

Yeah I just checked and having a diff game mode works

Phew

I thought I was going crazy

Now from a dev perspective I get why in OOP we'd want to use subclasses and such. In this particular case, does the same really apply to BPs?

As in the preferred best practice is to grab the main game mode and create two children with minor adjustments vs just duplicating the game mode and having two copies (parent classes) with their own changes?

[thin panther]

absolutely.

[stuck sentinel]

help this isnt working

[frosty heron]

U never add it to viewport

Also maybe don't use remove all widgets unless the scope is very minimal

This code would probably never gonna work since wbp main menu that calls it removed before you can even spawn the widget

If u have to remove the main menu to spawn the setting menu, then you are already doing it incorrectly imo

Let wbp main menu be a master widget that contain all of the settings new game etc.

[stuck sentinel]

ah im dumb

its the only way i found to hide the main menu

how else can i remove it

[native oasis]

I'm wondering if there is an easy or correct way to access this weapon target data in an animation blueprint? I'm using lyra. My goal is to use bone hit data to change hit react animations

[frosty heron]

You don't need remove anything. Add all the widget like setting new game load game to the main menu widget

[lethal night]

This is a quick one just as I cannot remember how to do it or if you can do it but how would I get a reference to my custom event for use with Event by timer without just dragging a connection straight to the node?

[frosty heron]

Simply hide the ones u don't want and make the one you want to interact with visible

[stuck sentinel]

how

[thin panther]

you mean the createevent node?

[frosty heron]

Drag the red node and type create event

Then link your ce

[lethal night]

Thank you, yeah I couldnt remember how to do it lol

[frosty heron]

I already explained it by words. Don't know what else to say

[stuck sentinel]

how do i hide it

what blueprint

[frosty heron]

By setting it's vissibility

I suggest to watch some yt videos, as trash as one video can be it should cover the basic

[eager thicket]

How do I get an isolated actor to take input from player 0? Currently pressing + doesn't yeild results

I tried auto recieve input: player 0 but no luck there

[stuck sentinel]

now how do i enable

[thin panther]

use enable input

though the ideal way would be to route input from the player controller through things like interfaces or event dispatchers

[eager thicket]

Thanks. Is there any reason why I'd want to do the "ideal way"?

[manic onyx]

is there any reason this cast would fail?

[eager thicket]

just for the sake of making code more scaleable?

[thin panther]

You can control everything in one spot, and when you want.

for example, enabling input on that, would mean whereever you are in the world, every single one will work off that input

[frosty heron]

It will failed if you didn't use bp game instance as your game instance

[manic onyx]

how do I check to see if I did

Im looking at world settings and dont see a game instance

[frosty heron]

Your project setting

[stuck sentinel]

guys i made a main menu but when i click anywhere the cursor goes away and i start looking around and i cant click on any of the buttons

[frosty heron]

Look for game instance then change it to the one you want to use

[manic onyx]

Thank you!

[frosty heron]

Set input mode to UI only. You are better off learning the basic. You will end up answering a lot of your own question

[eager thicket]

Thank you. But, where is enable input? I'm looking in bp details and I can't find it.

is it a blueprint?

[manic onyx]

This worked, thank you so much 🙂

[lethal night]

Is there a way of cancelling an input with the enhanced input system?

[frosty heron]

It's a node that lives in player controller but you probably use it for the wrong cause imo

[lethal night]

just wandering since cancelled is an output

[eager thicket]

ik ik i'm just trying to see if something works. I'll change it into a proper solution as I get closer to completing the project

[dim agate]

You might want to use mapping contexts.

[lethal night]

I am

Its more of a curious thing rather than I need it

just never come accross it so wasnt sure if it is something your able to do with just a node or something

[frosty heron]

@lofty rapids u want to make cpp blueprint function library?

[lofty rapids]

yes

[frosty heron]

File new cpp class and select blueprint function library afaik

Don't have editor rn

Any specific goal u want to do with the blueprint function library?

[lofty rapids]

i just need some functions to have more performance

bigger loops

[frosty heron]

You can make static function there so any bp can run the function

[frosty heron]

0o like?

[lofty rapids]

ya, that's why i wanted to use it

[frosty heron]

My first game is bp only project I did a lot of loop, no performance drop

[lofty rapids]

I'm generating levels, i'm storing the data in an array, i want like 10000 elements

[frosty heron]

Well it's not like I'm running any simulation

I see

[lofty rapids]

I'm getting infinit loop detected on large array

[frosty heron]

Yea gotchya

[lofty rapids]

trying to generate is just a pain, so i'm hoping c++ will give me what i need

[frosty heron]

U can increase the loop count but might want to move it to cpp anyway

Depending on what u doing, if the level is generated at the start , I would probably mask any possible lag with loading screen

[queen sphinx]

What variable would I need to get for a blue print that would determine how bright (units candles) a spot is?

Say how much light is on a rock in a room, based off of 3 stationary spot light sources within the room.

[thin panther]

not easy or doable in blueprint by default

well it is, but it's blueprint's main weakness

[queen sphinx]

Oh no?

Is there any ways to check light values on the surface of a mesh?

[main lake]

why would you do that ?

[queen sphinx]

Let’s say, I want an object to react based on how much light hit an area of a mesh. Like one side of a cube, if the brightness is x amount of candelas. Basically, want a monster to get weaker based on how much light is in an area. So if a player would shoot a flare gun, the extra light would determine weaken the monster. But if the light gets to bright, the monster will flee for darker lite areas.

[lofty rapids]

the problem is it just get in infinite loop and stalls for awhile, i think it's best for this particular stuff to be in c++. I'm generating a large array, with a pretty big string being built randomly for each one.

bp is just shitting itself

[frosty heron]

Sure thing

Why do you need a string for each one tho

[lofty rapids]

it's how i build the level

[frosty heron]

An int is probably way more performant than string

Like an id

[lofty rapids]

it's a string that i parse to put stuff in that section

it works great

[frosty heron]

If you could parse it as an int, it probably run faster on the loop but hey I can't tell. Never done anything like that

It's just a string is basically an array of character

[lofty rapids]

ya i need a big string

[frosty heron]

Comparing string will call forth another loop

[lofty rapids]

i'm just constructing

i'm not comparing untill later

https://streamable.com/yf8hnx

here you can see there is 10 sections

thats fine

but once i got 250 1000, 10000 it crashes

i can generate on the fly but thats a different mode

they are random levels

[neat gulch]

/ Edit: Solved by my own with range shifting to 0 - 360° and a specialcase if the rot is at 0 or 360/at the turnpoint

ok guys I have problem which I think is really simple but I still don't come up with a solution. maybe you can help.

In my game, the player can fly an airplane and collect rings when he flys through them. But there are also rings where you have to fly through and need to have the same angle as the indicator inside the ring, which points to the 'top' (with a tolerance +/- ~20 degrees).

The problem is, the relative rotation of the airplane (and ring) toggles from 180° to -180° and vice versa when you are upside down. Even if you add +180 it would switch from +360 to -360 I guess.

Do you have a solution which ensures, that the airplane can fly through the upside-down rings no matter it is rotated right-sided and has 180° or is left-sided with -180°?
Do I need a clamp? Absolute values?

[keen widget]

why it doesnt let me to call my custom event on my GameState?

[thin panther]

because you need to cast to your subclass

[keen widget]

thanks ❤️

[humble wigeon]

Hello, I have a bit of an implementation issue with the way I'm animating my turrets in my game using timelines.

I've got a timeline in my Turret's AI blueprint that starts at BeginPlay and outputs a rotation (Yaw) for my turret upper mesh to be set with, however whenever the player gets too close the timeline is stopped and the rotation is now set every tick with a RInterTo node until the player gets far away, but here's the issue.
My timeline at this point starts again, but at the time/rotation value it was when it stopped rather than start at the last rotation it was when the player left the turret range. How can I make the timeline start again based on the last rotation set by the RInterTo node?
Here's a screenshot of the function that gets called at BeginPlay and whenever the player gets too far away, and a gif that shows what's happening right now
https://streamable.com/njq8iu

Appreciate any help I can get on this 👍🏻

[restive lagoon]

is there any function to spawn actors based on their child components. The child components should have the same transform and the parent be spawned acordingly

[foggy escarp]

I'm not sure what you mean by 'Based on their child components', but the components are dependent on the root of the actors anyway. If you wish to retrieve information from the actor before its spawned, you can do so in a limited way using class defaults.

[restive lagoon]

Imagine spawning room1 with a door, the door is marked by a component, room 1 then tries to spawn room 2 and put room 2's door at room 1's door

[lofty rapids]

hmm

[foggy escarp]

ahh, okay. Yeah you can retrieve the component's world location and use that to calculate the correct transform for the new actor before you spawn it. This can be a little tricky though. You should be able to use the transform location node or the other similar ones.

[restive lagoon]

ty that should help

[agile pilot]

Can someone give me ressource (tutorial, example, guideline ...) for making trajectory path, that are not circle arc with start and end loc ? Constructing a path from the two loc variable, or modify a classic arc path ?

[foggy escarp]

@restive lagoon
The way I've done this is by using the local location of the component of both actors you need to 'attach together'. I thinking maybe:

1. Get actor A location, subtract component local location.
2. Spawn actor B, get component local location.
3. Set actor B world location to the result of (1) - (2).

I might just be spitballing though. Chat GPT will probably be better at explaining it.

[vestal sapphire]

How can I make enemies more spaced out? So that there's a wider "no-go" zone around each of them?
I'm trying to get the NavModifier to do that, but I can't manually set its size. It's tied to the size of the capsule collider...

[honest bough]

Anyone up to show me some stuff they consider intermediate for Blueprint Usage?

I’m trying to make games, and just have a better understanding of blueprint programming generally

So having a higher understanding of intermediate concepts helps me a lot

[cyan harbor]

hello can someone help so that when the timer finishes it will subtract customer satisfaction by 10

so far it keeps outputting still got time with my debug menu saying that time variable is going into the negatives

[zealous moth]

add a check for the player character

[zealous moth]

you used the right word timer but you didn't implement one. Don't use tick or delay. Instead use a timer function.

worst case look up timers

[cyan harbor]

wdym a timer function

[zealous moth]

https://www.youtube.com/watch?v=qc5WpNq7RFg @cyan harbor

[keen ore]

What do you mean? Do you mean add a branch to check if the player charater is still in the area?

[zealous moth]

yep

[noble junco]

Does anyone know if there's a way to make blueprint interface functions pure?

[keen ore]

it didn't seem to work

[zealous moth]

no no, do get player character == other actor -> branch

you want the other actor to be your character

[rich ferry]

I want my tank to look at the position my camera is looking at, but it only rotates about halfway there. I've tried a few strategies but a lot of them result in the turret not moving at all. I was wondering if maybe the problem has to do with taking only two outputs from the rotation vector, but if I trace along the forward vector of target rotation, it appears to be where the barrel is looking (i.e. wrong). If I trace along the start and end of the "look at" input, it goes where I want it. I've been trying to debug this for awhile, very confusing.

[pure walrus]

predict projectile path just aint working properly

just came to say that

[pure walrus]

maybe hard set it with "make rotation from 3 axis"

[rich ferry]

I LITERALLY just figured it out. Right as you replied lol. I needed to use "Find Look At Rotation" instead of "Look At Function". Idk why. But it works like a charm now.

[pure walrus]

true, i thought it was a ue5 thing, congrat ;)

[rich ferry]

I have another issue with translating world space to screen space if anyone knows anything about that. A lot of people online say it's an engine bug. Not sure how to get around it, the UMG channel couldn't figure it out.

[vestal sapphire]

I don't understand why this doesn't work. I have AI enemies. I added an additional sphere collider for them, so that they don't crowd together, and made a special "enemy" channel so they only collide with each other.

But they do not care. They go move through it, and only collide using their inherited capsule collider.

I disabled Auto-Weld. What other setting could I be missing to make it work?

[neat gulch]

Has anybody found a solution to this problem yet?

[main lake]

I'm not sure to understand, like you want your player to pass when it's 180 or -180 ? If yes, then you can use the ABS node to always give you the angle without its sign, and it will return to you 180° for both cases and you can do a check there to do whatever you want

[atomic saddle]

set actor locations and rotations doesnt work in the level blueprint for some reason?

this does not work btw

[neat gulch]

The thing is, if I use absolut values, a ring which has a rotation of -90° will also be collected if the whale flys through with a 90° angle

[cedar sleet]

question, im running a sphere trace and im trying to get the actual location of the impact which would be where the sphere intersects the wall (where i marked red). any suggestions to try?

[thin panther]

I mean, they do. Not that you should have been handling this in the level bp anyway

doors and such should really be their own thing

[chilly plover]

Whats the best way to remove a widget?

[ancient topaz]

Friends, I can't figure out one problem.
I want to create an information widget, which will display information about the actor, with which the character interacts. And if I have no problem with the text part, I can't figure out how to make the image in the widget change depending on the actor. More precisely, I can't add an image to the widget from the actor, because having created the image variable, I can't pass it to the widget.

[strong turtle]

Hey, why does my mesh's Collision object type override the StaticMeshcomponent's i have for the mesh in my actor? Is this avoidable?
Solved: Disabled "Customized Collision" in the mesh's collision settings. Weird that this was on

u want to check off the image variable box in the widget blueprint and then do interaction stuff

and on interaction which u can do in ur player bp call the custom event in ur widget that changes that image

Hey

quick question guys

i have this char actor, AI_ENEMY, I setted after it's life reach <= 0, he play an animation, [Death one, he fall on floor] But, the initial position it's still there, and can colide with anything

how i can disable the collision of it

in BP

get enemy hp > if E.hp <= 0 > ...

[turbid pecan]

More adventures in blueprinting..
Trying to find a way to set rotation on my pawn, however most of my code is inside the controller bp which responds to key strokes. So I can rotate the pawn from that BP using get player controller > set control rotation

But I am trying to do this via trigger now. So I have a trigger box, which can only allow me to use the overlap event in the level BP, which in turn does not seem to let me access stuff like the control rotation

Any tips?

[inland monolith]

Hi! I have a bit of a dumb question, I'm trying to communicate between BPs using Interfaces but can't get it to work.
I've created a BPI_Interact and integrated it in BP_InteractedEgg. When I overlap with BP_InterfaceButton, it should destroy BP_InteractedEgg, except it doesnt. I've checked and the overlap works but it seems the communication doesnt work. Thanks a lot for the help 🙂

[robust isle]

Has anyone else experienced this (seemingly random) issue of blueprint actors having a blueprint added component just stop saving/loading data? When this happens you can modify values on the component and they'll work in editor, but the asset doesn't get dirtied. If you reload the editor (after making sure to save the asset anyways) the component will only have default values.

Only way I can seem to fix it is to delete then re-add the component. Which is pretty tedious.

So far I think I've only experienced this with my own custom components defined in C++ so I'm not sure if I'm missing something there

[lunar sleet]

could be bp corruption if you're hot reloading away

[robust isle]

Actually, yeah that looks like it. https://forums.unrealengine.com/t/hot-reload-on-native-actor-component-can-lead-to-blueprint-corruption-and-data-loss/265048

It can also cause other odd behaviors in the editor session since a native CDO is potentially now being modified inside the Blueprint editor unintentionally.
I was experiencing multiple objects sharing the same variables when I would edit it and now that part makes sense

[lunar sleet]

the #cpp legends can prly give you more tips but the general consensus is to use Live Coding but with Hot Reload and live re-instancing checked off in editor settings and to create cpp classes directly from the IDE, I believe there's an extension that has a wizard for it

[robust isle]

By Hot Reload are you referring to this setting? I already make classes from the IDE but you don't need to make new classes to trigger this bug it seems. I'll look at the reinstancing setting and how it affects things

[lunar sleet]

uh they may have changed how it looks since last I checked lol

I'm checking with #cpp

[celest tangle]

Having an issue where a parameter that is passed into a custom event call gets overridden if the event is called again. Shouldn't the event calls be independent of each other?

[frosty heron]

Show screen shoot

[celest tangle]

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

https://i.imgur.com/bZ9nu4c.png

Two different items overlap the box at different times. The 2nd item's name is the only one printed once it overlaps.

[lunar sleet]

is it the same item on different clients ?

[celest tangle]

Its standalone in editor testing; number of players = 1

[frosty heron]

Ofc, if u want both of them you need to get all overlapping actors

Add them to an array

Also the code looks cursed, I hope it's just for testing

You can use timer for w.e u are trying to do

[celest tangle]

Why does the reference of the first item go away though?

Shouldnt the first overlap call just go on foerver?

[frosty heron]

Also tips for multiplayer, the overlap happend on both server and client. You need to think what should run on server and what should run on client

Normally I just don't run anything on client for an overlap but it depends on what you want to do

[frosty heron]

Overlap happend when an object overlap with something

[celest tangle]

Right so, object A overlaps and is passed into the moveObject function, which should repeatedly print that object's name forever?

[frosty heron]

No

If you overlap with new actor you gonna print the latest other actor

Just as you witnessed

[celest tangle]

Hmm, why is that?

[frosty heron]

Attached item no longer pointing to the same object?

[celest tangle]

I thought that event calls were independent of each other? Like function calls? So you could pass in a param and it creates a local var..

Is that not so?

[frosty heron]

Not really

[celest tangle]

oof D;

[frosty heron]

That's why there is some limitation

I could be wrong, just a newbie

But I had this issue with function call

When I need to load soft references

You will need to encapsulate function in component or use delegate to solve this issue

If u don't let's say I have a function that load object.

I'm trying to load object 1 then i load object 2

If object 1 load slowe than object 2 my mesh will end up with object 1 even if object 2 get called last

Another example would be calling function with timer

[celest tangle]

kk ty for the info 😄

[ancient siren]

i might be overthinking, but how do i get the player bone that overlaps with another object? (i want it to print out the player's bone)

[frosty heron]

Btw I could be wrong with the delay and going on a loop like that. I have 0 code that looks like it but when you call the print string it just runs to get w.e the attached item currently is

[visual stump]

Hello I was looking of someone could help me with a 3rd person interaction system?

I want to do something like the interaction system in God of war. It seems to work mostly based if the objects are close enough to the player and not really if the player is looking at them. So i was thinking of using a collision box in the bp player, and whenever a object that implements an interactable interface I created I would add that object to a list, and whenever it leaves I would remove it from the list. And when there is more than 2 objects in the list, it would look thorugh the list and just let the player interact with the one that is closer. But then I started to face a the problem that there are interactables that have more than one collision so the overlap function would be called constantly and even though I have the list of actors, functions like find and contains do not work like that because is just a list of references. I think there has to be a easier way to do this, all I can find on internet are interaction systems that uses a ray from the player camera, but that wouldn't work as I intend.

If someone has any advice I would appreciate it a lot, I've been stuck on this for a while now

[frosty heron]

Make a custom collision channel for your overlap

[visual stump]

But even if I have a collision channel I still have the probelm on overlap ends, because I can't use find in the array I have of the objects inside the box

[lunar sleet]

I'd say you're at least at least Intermediate status, since you know cpp 🙂

[frosty heron]

Nah just enough to refactor. I can't read anyone else code 😢

[lunar sleet]

can you read this? I found it too be the most work Epic's doing for us in a function #gameplay-ai message

[frosty heron]

Why is that? Point here is u only want to overlap with the item and don't care about other comp of the item

[lunar sleet]

you just plug that into an anim instance and it finds the AICon, Casts into it and gets the brain component for you to pause the logic, it's crazy lol

and that's a bp node under the hood

[visual stump]

Wait sorry I was using something wrong, yeah the find and contains works, and with the channel just for interactions is working fine for now thanks. I was having a problem when I call the end overlap and wanted to find the actor that leaved on the list that I had, I was doing something wrong there, so its working fine now thanks

[frosty heron]

I can read this yea 🐱

[lunar sleet]

there you go, you can read someone else's code 😛

[frosty heron]

End overlap get the comp then make a check against it maybe

[frosty heron]

Everytime I try to read source code I got lost

[lunar sleet]

I tend to as well but that was surprisingly legible

[frosty heron]

And my brain goes to blueprint automatically when looking at cpp stuff

[lunar sleet]

Miezko prly wrote it tbh so it'd make sense

[frosty heron]

If it can be written in bp then I can read it 🤣

[lunar sleet]

yeah, fair enough, that's technically a bp node

[frosty heron]

90% of the time I don't know what the cool kids talk about

[lunar sleet]

I feel you, my head starts to hurt when I read some comments in #cpp lol

[frosty heron]

https://tenor.com/view/cat-shades-sunglasses-cool-gif-8617253

We will get better in time

[lunar sleet]

then we can communicate with Laura at a higher level 😄

[oak fable]

hey there
so i have a wired bug or maybe it's something i don't understand
so I'm setting a bool in my player bp and one of the items that bool is used in the animation bp so i can check if i can do blend by pose or not
the thing is when i use the blend poses by bool the anim montage wont play but without it it works fine
and i have to use the blend poses by bool because some tool or animations i don't want the character to do the layered blend with it

i hope what i said makes any sense 😅

looks like somehow the layered blend didn't have the bone setup so i did that and now it works for top part when its true which still doen't make any sense

[solid vault]

how do i change teh direction that the character is facing ?

[oak fable]

depend on how you want to achieve that like using the mouse input or movement keys
i suggest to look at the third person template you might find what you want there

[oak fable]

what i see now is the blend poses by bool it works but reversed
so true is false and false is true which is so wired and that's the first time to happen
like i see the debug lines goes correctly but the values doesn't 🙂
anyway reversing my bool fixed it another editor bug or whatever

[foggy sundial]

Is there a way to run two standalone PIE instances with different launch parameters?

[oak fable]

anyone knows why that error

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetGroundItemRef_Ref". Node: Set LocalHealth Graph: HarvestGroundItem Function: Harvest Ground Item Blueprint: BP_Player_Character

it used to work fine but now it gives this error and i haven't even touched it

nvm that's unreal just needed me to go and re-reference everything again

[gentle urchin]

Interesting use of interface and encapsulation

Sounds like harvesting would be a generic player action, with a specific implementation on the target actor set up in some hierarchal manner

definetly not coded in the player bp, with hard values

[oak fable]

that one harvesting is in the player bp but not with hard values
also its not gonna be generic or pure harvesting but that's what i need that key for at the moment still going to make the interaction system and check for what i I'm overlapping with and based on that i will do the next actions

[gentle urchin]

this is a hard value

and you're allowing an external bp to handle what's typically internal bp values

[oak fable]

yep just for now to test

[gentle urchin]

The interface also seems wasted here, when you can just use a cast

[oak fable]

still didn't make the damage logic and other stuff for it

you mean for the reference interface ?

[gentle urchin]

yep

[oak fable]

isn't it better then casting ?

[gentle urchin]

Not when used like this, no

you'd have the interface for giving a un-related set of actors a chance to implement the harvest interface

giving common functionality across totally unrelated classes

[oak fable]

got it thanks for the advice

[dusk saddle]

Hey everyone I am having a lot of trouble with interfaces, I have watched the video but the thing he is doing is a lot different then what I am trying to do
I am pretty confused.
All I want to do is after my trigger box finishes its main tasks, I want it to send a interface message to an object (a light) to make it flicker on and off a few times.
Any help is really appreciated.

I had the idea of drawing a sphere so it could find the spotlight, but idk if thats even how I would go about doing it.
Thanks.

right now, im just trying to confirm its getting the signal and its not working

[edgy field]

In my character's construction script, I basically spawn a camera actor and use SetViewTargetByBlend to switch the camera view to my CameraActor.
However, changing the position of my CameraActor doesn't change the CameraComponent's position except if I .. within the editor .. move the CameraComponent relative position slightly once.
Any idea why this happens ?

[dusk saddle]

I finally got it

[earnest vigil]

Hey all! Any idea how I would go about spawning actors in a specific area like in this image? Lets say this circle is the level but I only want the actors I am spawning to spawn randomly anywhere in the red part but not the orange or blue.

[gentle urchin]

Outerradius, inner radius

[earnest vigil]

It could be any shape of course by the way

[gentle urchin]

Random float in range(min, max) for the distance, and random float (0,360) for the rotation

Any shape?

The logic differs between the basic shapes

Circle/square

[earnest vigil]

Square would be best then

[gentle urchin]

Brute forcing it is fastest 😅

Random point in bounding box NOT inside smaller bounding box

[earnest vigil]

oh yeah i guess thats fair

[gentle urchin]

Fastest to program* not in actual execution speed

[edgy field]

short term*

[earnest vigil]

Is there any way to get the bounds of a landscape?

[gentle urchin]

At that point id suggest spawn areas

[edgy field]

there must be smth, but could take time to figure out

[gentle urchin]

It would perform worse the larger the bounds are

[earnest vigil]

true

you think just like 4 spawn areas on the edges would be best?

in terms of performance

[gentle urchin]

Sounds reasonable, yeah

[earnest vigil]

Better than 2 bounding boxes?

[gentle urchin]

Yeah

[earnest vigil]

Okay thank you appreciated

[chilly sundial]

I've got a conceptual blueprint question here.
I have Modules, Spawned Modules, and Missing Modules, all of Struct Module.
This makes it easy to find missing modules like in the screenshot.
Now I need to extend Spawned Modules with an Actor Ref, because I need to reference it later.
I can't/don't want to extend Struct Module, because this is intended to be 'master data', which doesn't hold runtime data (if that makes sense?).
Modules and Missing Modules would also have this Actor Ref and it would mess up my simple logic.
There's probably some way which I don't know of, how to 'extend' (?) the existing Struct Module easily? Or maybe not?
Something like a pointer to another array holding the Actor Refs?
Hope this is understable...

[celest island]

whats the difference between placing an actor, for this example SM_Cube, and placing an actor and converting it to a BPP and adding individual components too it? Having issues with a CPP class and it identifying seperate actors. 1 group is the SM_Cube example, adjust too look like a small building. The Other is an Actor converted to a BPP with a Scene that holds a similar structure made up fo static meshes.

wrong channel

[edgy field]

Solved by Spawning on BeginPlay instead of at the constructor level

[lunar sleet]

Idk how you managed to use spawn on construct in the first place but yeah

[solid vault]

why is this not being triggered at all ?

not evne printing hello

it turns out i need t ohave a collider for that actor aswell

why ?

[thin panther]

Because you can't overlap something that has nothing to overlap

[solid vault]

okayy

also another problem

it says taht my player controller reference is invalid in my game instance

[thin panther]

Yes it probably will be

[solid vault]

is it because init is run before the player controlelr is created ?

[steady night]

hmm dose this overrite ?

if i fire it twice before the time ends, will it overwrite the time or just call 2x events ?

[thin panther]

Yep

[solid vault]

whats another event then i can use ?

or i have to just create the refernce when i need it ?

another question. why is my pass by ref not working ?

i have this update coin count event in my hud WB and it should take a "coins" variable as input but pass by ref. i checked if it did affect the original variable but it didnt

[dry sleet]

Well, how does the function look

[solid vault]

nevermind i got it to work

[fiery swan]

Topic AnimationBP optimization
I have 3 optimization stages for NPCs
Max quality - full anim bp with idle animations, idle breaks, locomotion, etc.
Low quality - no idle, still allow idle breaks and locomotion.
Freeze - disable all animBP

max and freeze are easy enough, but Im wondering how to optimize the low quality a bit more.
Currently whenever any animation is played on an animation slot that isnt "idle", it will enable tick of the skeletal mesh, once that is finished and no animation slots are running, it will disable tick of the skeletal mesh. this already saves a significant portion (120 npcs on max ~30fps, on low ~50fps and on freeze ~70 fps) but I wonder if I can do more.
any insights appreciated, thanks!

[gusty junco]

Is there a way to not have any root component on a blueprint actor?
I have an abstract base class, and I'd like to decide the root component in the children, however this doesn't work if there is a DefaultSceneRoot or any other component in the base class.

I can easily make a C++ base class for this, but it seems a bit silly if it's not possible to use blueprints for this, so I'd like to know if it's something I'm not getting?

[young meteor]

Hey folks

I'm trying to decide if I need to learn and dive into Unreals GAS system.
I'm creating a tower defense, but will be adding "skills" like multishot, shield dome, piercing, healing aura, mana burn, mana on kill, etc.
It is not multiplayer (I've seen GAS is great for handling that aspect), and I feel like coding the above in normal blueprint code is fairly simple.

I'm afraid I might be surprised later with how complex it gets when/if I get many skills, perhaps with status dependencies (like burning).

Do you guys think it is a system highly worth learning that is relevant in my case?
The tutorials I've seen involves C++, but on top of that it seems tedious to work with (making each effect separate, stat sets separate, etc).

I don't think I would benefit much from the animation side since I don't really have any at this point.

Would love to hear your thoughts. Thank you. 🙂

[thin panther]

Absolutely worth it

[young meteor]

That is a strong yes. Any specific reasons?

Because you are thinking long-term (multiple games), or even just for this game I'm working on?

[thin panther]

Just for the game you're working on. Built in support for blockingz conflicting, DoT, adding new ones etc is a huge plus

More simply, if you're using abilities, use GAS

[dark drum]

How much C++ does GAS require at the moment? It's still something on my radar but my C++ skills are errmmm... Yea lol.

I think the last time I looked you needed a C++ base so you could implement the IAbilitySystemInterface for getting the Ability System. (I couldn't find it in the list when trying to add to a BP)

[young meteor]

I'm no expert, but saw a few videos where he sets it up. Think we are talking 30 minutes of C++ setup, and then it is almost entirely Blueprint from there. Perhaps a variable setup in C++ once in a while, but in general Blueprint after that.

[young meteor]

Okay. Thank you for the input.

[thin panther]

Not a whole lot at all. There's a minimal tutorial pinned in #gameplay-ability-system

[dark drum]

Thanks, I'll check it out. I always forget about the pinned posts on discord.

[frosty heron]

Laura posted it recently anyway, u didn't miss much

Afaik the setup is quiet minimal actually. Rest can be done in bp

[steady night]

Hey guys im using this to check if "damaged actor is player and the damage is from a player"

[dark drum]

Yea I noticed. Here's hoping 5.4 they let you do the initial setup via BP lol.

[steady night]

but im getting this error when an NPC is attacking

idunno why

or well i get since its NUlL

but can u get AI controller ?

oh you can..

ignore

[sharp ridge]

Hello, does anyone know how I could make grass generate procedurally in my game?

[main lake]

No, that's not how you do that. From your Event Any Damage, you have to cast your "Instigated By" pin to your player controller, then if it succeeds, then that means the damage was caused by a player

[steady night]

@main lake thats one way of doing it but my way worked aswell, without a casting

[main lake]

you way is more complex for nothing 😄

[steady night]

well you save a cast so wroth it X)

[main lake]

so it's good to take good habits from now on

[main lake]

But I think all of your nodes take more resources than a cast 😛

[steady night]

id say no but im not sure

[main lake]

me either 🤷‍♂️

Guys, how do you work with something that needs an animation but you don't have an animation to test it ? Like imagine you want to make the character go through a window with a specific animation but you're not an animator and don't have that animation (also here I'm talking about animations that you don't find on the internet to download and test).

[sharp ridge]

Hello, could someone tell me why it is giving an error?

[thin panther]

Are you in a game mode?

[sharp ridge]

yes

[thin panther]

Then your error is in those functions

[sharp ridge]

i get a crash

[sharp ridge]

pf i dont know, Im new on this

[thin panther]

You're accessing something in an array that is pending kill, so find it, and don't access it

[sharp ridge]

It is this blueprint, the delete function is so that grass is generated and the one behind is deleted to remove resources

[main lake]

Anyone ? ☝️

[kind willow]

Then you just don't play the animation

If you don't have an animation to test with, but want to test anyways, you just test it without the animation

[main lake]

but how do you make a player go through a window without an animation ?

[kind willow]

You don't. if your system is dependent on an animation existing and you don't have an animation, then how is the system supposed to work?

[main lake]

That's what I'm asking 😄 And games rely heavily on animations, so you don't create games when you don't have animations ? 🤔

[frosty heron]

you can just move the capsule, but if you need to use root motion, then you will need the animatioon

Example would be vaulting or climbing

i seen it done w/o animation. Get the capsule to move firstt then animation coomes lateer

[kind willow]

Then you use a place holder animation or, as SoldSummer said, you don't base your system on an animation playing

[frosty heron]

there are free animation packs in market place

[main lake]

how do you make the capsule go through the lower part of the window ?

[frosty heron]

i can't picture that, also no idea. I'm newbie

[main lake]

But if you have a custom skeleton it creates and issue

[kind willow]

I imagine a timeline attached to a transform would suffice

at leats for testing

[frosty heron]

Use skeleton that can be retargeted to Unreal Skeleton for easy mode

[main lake]

Interesting

[kind willow]

I have a question of my own, actually. How do I add vertical velocity when my movement mode is set to swimming? I tried adding movement input in Y axis, but it only propelled me slightly up, no matter how big the input value was

[main lake]

try to change the velocity vector on the upward axis ?

[kind willow]

Velocity vector is the result of movement, no? Not the cause of movement itself

[frosty heron]

Afaik input value gooes from -1 to 1?

it don't matter how more you put

that's not what driveen the speed

if you are using Character Moovement component, I'm gonna guess it's the walking Speed

[kind willow]

This value

[true valve]

Anybody knows why I can't get the bone name of the target when I hit it with a projectile.

[kind willow]

What are you using to detect the bone name?

[true valve]

As far as I knew you'd need a physic asset in your mesh which I do.

[dim agate]

Correct me if I'm wrong but the player character is likely always loaded and thus casting to it shouldn't be costly.

[steady night]

well regarding casting ive heard ppl say differently some "avoid it at all cost" some "cost nothing if used properly"

in to much of a novice to know

[frosty heron]

No, you heard tht from youtubers who knows no better

[steady night]

but i need it to learn so i use it whenever .p

well yeah some of them

[frosty heron]

they are very mistaken, and used to fool me too

U shouldn't avoid cast

[steady night]

well ive neeever had any issues related to casting so

yeah i agree*

[frosty heron]

cast to base class when possible

Dont use interface to avoid class, that's aanoother bad advice

[dim agate]

That's the same issue with event tick, people say "avoid it" because they find out it was tanking performance but the real problem was mis-use.

[frosty heron]

Casting in bp land loads the class, that's just the price you have to pay for using bp only.
Player character will always be loaded, so cast away it's free

[steady night]

well event tic i can understand more ofc missuse is bad

but generaly i try to avoid tic if i can

[frosty heron]

It's easy to distinquish what belong to tick and not

if u neeed soomething done every frame (eg movement) then use tick

if you care about performnce then control what you want to load with soft ref

[steady night]

Aye

I only use tic for ui atm

Thats bad but 😅

[dim agate]

I do too but it's temporary.

[elfin lagoon]

does this event triggered when an object comes out of a sense range (or become not valid bcz dead and removed from a game?)?
or its only triggered when an object comes in a sense range?

[hearty sapphire]

So I’m making a pinball game and for the pullback mechanism what would I use to stop the player from pulling it back too far? This is a vr game.

[main lake]

clamp the value

[hearty sapphire]

Can you clamp to a position in the world?

[main lake]

Yes

[hearty sapphire]

Ok, I’ll check it out thanks

[radiant talon]

Hey guys i was wondering how can i implement a clamp with my ball. My ball can go forward but with time it goes too fast and goes trough object. I want set max rotation from the ball but im trying to figure out if its with the sphere or the impulse.

[lofty rapids]

maybe https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Math/Vector/VectorClampSizeMax/

might help but i don't think it will stop the impulses

[radiant talon]

thanks im gonna try that if not ill try another way

[lofty rapids]

you can clamp the amount, but it will still be added to impulse

[lofty rapids]

from the doc, "Impulses are accumulated each tick and applied together so multiple calls to this function will accumulate."

https://docs.unrealengine.com/5.3/en-US/BlueprintAPI/Pawn/Components/CharacterMovement/AddImpulse/

" If you want to continually apply forces each frame, use AddForce()"

[hearty sapphire]

My pin ball mechanism when being pulled back goes off of the world axis value but the object is at an angle like the board should be. Is there a way to make the object move backwards parallel to the board so it will move relative to the board?

[lofty rapids]

perhaps relative location ?

[lofty rapids]

is the actual thing rotated, or just the mesh in the actor ?

[void jewel]

any setting that could keep me from being able to use set rotation on a skeletal mesh inside an actor blueprint? I can rotate the actor, but not the skeletal mesh inside - no matter what kind of node

it is moveable. I even tried to detach and then rotate it

[hearty sapphire]

So all that’s changed is the object was rotated to the angle that the board is in the class that the boards on not the class of just the mechanism

[lofty rapids]

i'm not sure i know what you just said

i'm just a little confused for some reason

[hearty sapphire]

So the launchers angle was set to the board in the class the board is in. The mesh was never changed. I’m not good with how to word this issue

[radiant talon]

Okay yea the impulse is good but i think the ball rotation is the problem the speed is fine but i think the rotation of the ball is spinning too much that its giving more speed which gives clipping trough the walls

[lofty rapids]

np, i'm stil fairly new to unreal things don't click quickly, but is the launcher a mesh, or an actor ?

so the launcher is a mesh ?

inside the board actor ?

i would try to rotate it, then move the z relative not sure if it would work

maybe because your using world position, it's going straight back

or maybe move it by forward vector

[hearty sapphire]

It’s an actor, I created an actor bp class and put the cylinder that is the launcher in. Then I have my board class which is also an actor that I’m attaching all the other items for pinball to. The issue is when pulling the plunger it goes straight back rather than the angle it’s set too. I am using relative location but it still only moves along the world axis not relative to the board. I don’t know if this helps explain more.

[lofty rapids]

how are you changing it's value ?

just setting the y, or x ?

or z

setting it's location with either one of those won't follow rotation i'm pretty sure

i think you may have to use forward vector

[hearty sapphire]

Ok I’ll give it a shot thanks. Sorry for the confusion.

[chilly plover]

Any good tutorials for fps walking upstairs?

[lofty rapids]

you could actually use another component like an arrow or invisible cube that you move to as well

[jovial kettle]

Does someone know a alternative for this custom node? I tried something (pic 2) but it isnt the same as the custom node. I need it to migrate it into uefn

[restive lagoon]

im not a mathgenius and ive been stuck on trying to get two objects to face each other by setting the rotators, feels like im so locked in on it that i cant find my mistake, how would i go about it? I assume getting the normalized rotation and checking if they add up to 180?

[lofty rapids]

maybe somthing like https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/Rotator/FindLookatRotation/

[restive lagoon]

i mean, i could just create the same level instance BP multiple time with different origins to fix the entire issue

i just dont understand how to add/subtract rotators , all i have is combine rotators and inverse

[unique wasp]

Does anyone know what can cause these broken graphics in UE5.3? In a shipping build whenever I press F11 twice (to go to and from fullscreen), the art is broken after that. Ever after restarting, it remains broken. The only solution I've found is deleting my save folder.

My first hunch is that this might be something with Lumen, but after disabling Lumen in project settings there's no difference.

This happens on several computers in our office. My own laptop has a Geforce 3050 Ti laptop GPU.

[lofty rapids]

is it something with the ui ? @unique wasp

or the actual game ?

[unique wasp]

@lofty rapids It's the actual game. These are weird 3D shapes that somewhat approximate the geometry of the buildings underneath, in a very weird way.

[sweet silo]

yeah

[dark drum]

What should it look like? A side by side might be useful to help identify the issue.

[unique wasp]

Houses on a flat ground plane. I can't share a proper screenshot due to confidentiality unfortunately.

After some experimenting I've found that if this is in GameUserSettings, it's broken:
sg.ResolutionQuality=1

When it's sg.ResolutionQuality=0, it works fine

[steel shadow]

Hello quick question, Is saving every 5 seconds considered a bad Idea ? I'm saving 2 strucs only ?

[main lake]

In game or in editor ?

[steel shadow]

in game

[sonic vine]

Hi all -- I have been trying to figure out an issue for a while with widgets.....I have a gameplay player controller that adds all the widgets, but I purchased this guys pack off the marketplace that uses a spell component to add the users spells to viewport. My question is will there be an issue if I try to add the widget from 2 places and manage them? Right now its failing but want to know if I should stop and re-design the thing i purchased

[main lake]

I don't see any issues with that but 5 sec is maybe too short, save stuff like every 5 minutes instead

[steel shadow]

I was tempted every 1s because it's the inventory :x

[thin panther]

It's not necessarily awful. With saving much more you will notice a hitch in blueprint.
That being said it is a quite short autosave delay.Typicall you find it as 1 minute/ 5 minutes/ 10 minutes, as most of the time in 5 seconds you won't have done anything worth saving.

If you think about it, a majority of those 5 seconds will be spent with the inventory identical to it's previous state

[gentle urchin]

you could save on change

[thin panther]

Some games opt for saving every time you pick something up

[steel shadow]

For now I save on open/close inventory

But seems like a bad idea

[gentle urchin]

yepp

if you need to, save everytime sometthing in the inventory changes

or atleast when something is added/removed

[steel shadow]

Yeah that's what I'm going to do aha

thanks

[main lake]

I have a question : Is there in Blueprint the equivalent of Polymorphism in classical programming ? Like having multiple functions having the same name but different parameters ?

[thin panther]

No overloading doesn't exist, but polymorphism does

overloading is a smaller subset of polymorphism

If you cast to a code only base class to call a function, that's polymorphism

[main lake]

I'm not sure to understand. Isn't Overloading when you have a method on the parent class that you override in the child class ?

[thin panther]

that's overriding

Overloading is when you have multiple functions distinguished by differing parameters

[gentle urchin]

Transform(float)
Transform(float, float)

[main lake]

So that's "Overloading" and not "Polymorphism" ?

[gentle urchin]

polymoprhing would be something like

Animal
MakeSound();

Dog : Animal
MakeSound{
Bark();
}

Cat : Animal
MakeSound{
Meow();
}

[thin panther]

// Overloading
int add (int a, int b){
  return a + b;
}
int add (int a, int b, int c) {
  return a + b + c;
}

class Foo {
public:
  virtual void DoStuff();
};

class Bar : Foo {
public:
  virtual void DoStuff() override;
};

Foo* ptr = new Bar();
ptr->DoStuff(); // Calls Bar::DoStuff, is polymorphism

[main lake]

weird, to me the best corresponding word to that would be "overriding" because it "overrides" the parent method with its own method (on the child)

[gentle urchin]

override != overload

overload is like... you overload a truck. so a bigger truck has arrived 😄

[main lake]

yeah but the choice of words is weird

[thin panther]

they make sense

[main lake]

I think I learned it wrong the whole time, because the first example you gave I think my teacher always called that "Polymorphism"

[thin panther]

it is

[main lake]

https://tenor.com/view/huh-rabbit-cute-gif-15676652

[thin panther]

See: "Overloading is a subset of polymorphism"

A carrot is a vegetable, but not every vegetable is a carrot

all overloading is polymorphism, but not all polymorphism is overloading

[main lake]

if Overloading is a subset of polymorphism, why your second example doesn't have a proper name instead of being called "polymorphism" too ? 🤔

[thin panther]

It does, that's called function virtuality

but it was besides the point

[main lake]

oh that's the keyword "virtual" in cpp

[gentle urchin]

yeah

[main lake]

finally I understand what that keyword does after 4 years 🥲

[thin panther]

if you want a deeper understanding, look into something called the v-table
https://en.wikipedia.org/wiki/Virtual_method_table

[unique wasp]

okay turns out resolutionQuality=1 means rendering at 1% of the resolution and then upscaling. resolutionQuality=100 is regular resolution, and I'm guessing the default resolutionQuality=0 means it uses 100 instead.

That leaves the question: how can I set resolutionQuality in runtime? It seems to not be available from the UserSettings BP

[dark drum]

I believe you can set it via console commands which there's a node to call them.

[unique wasp]

I found that, but executeConsoleCommand isn't available in shipping builds I believe

[dark drum]

As far as I know they still work, it's just the Tilda key button that doesn't work to be able to type them.

[steel shadow]

For check/unchecking Savegame how one must proceed ?

[thin panther]

ignore it, it doesn't do anything in bp.
it's a flag used for automatic C++ saving systems

[steel shadow]

:3 okey thanks

[timber crystal]

hey i need help with my animation sprite when he dies it looks like that:

i try it with an offset but nothing happend

[frosty heron]

try to offset the mesh component instead

[timber crystal]

ok let me try thanks coldsummer i check it out now

[frosty heron]

or just fix the anim in the flip book

[timber crystal]

cant do it there i try it ...

but let me check it with the bp

[frosty heron]

get a ref to the dying char -> Get the mesh component

[timber crystal]

ok let me see

[timber crystal]

is in that case the mesh component the sprite flipbook?

because it dosent work like that

[frosty heron]

target shouldnt be actor

froom yoour mesh comp, type add local offseet, tho you will proobably neeeed timeline on top, by the look of the video

[timber crystal]

okok thanks i go for it

[stable moon]

Hey guys! I want to ask you for help 😦 ... I have a bug with teleporting the player. I have a a hollow cylinder around the player area and when the player leaves the area then he will be teleported back to the area but from unknown reason the teleport(teleport, setactorlocation, etc.) does not work

[cyan jetty]

how can i change the "Name Chaarkter" so that only the "CharakterOwner" can see the Name?

[cobalt gulch]

Why is this not saving/loading properly?

This is in the game instance

[frosty heron]

@cobalt gulch check your saved folder

do you have any .sav there

[cobalt gulch]

whats the folder

[frosty heron]

your project folder/saved

for editor build

[frosty heron]

for package, it will be stored somewhere else

[frosty heron]

are you testing on package or Editor?

[cobalt gulch]

editor

[keen widget]

I didn't know that cr1tical is ue5 game developer

[frosty heron]

@cobalt gulch it should have a savegame folder

if you actually save that is

You probably want to check if you are actually saving the savegame object to debug

@cobalt gulch Have you created your save game object? Print string it when you save game to slot, make sure it's not null

[undone bluff]

one of the clones ought to have picked up a hobby

[grave apex]

does anyone know how to use this variable type within a struct?

[frosty heron]

Ye but in cpp

[grave apex]

aarg

[frosty heron]

I don't know if you can get a world reference in bp struct

If i Type world, nothing comes out

[grave apex]

I saw a little bit of this video: https://youtu.be/HpUhfnHCENQ

do people actually use objects instead of structs like that?

or is that just this guy

[frosty heron]

Depends

very different usage. Objects is something you can instantied and reference

Struct is more like a template (I am bad at explaining btw)

[grave apex]

yeea, I dont necessarily want to have to instantiate it

just kinda wanna have the variable type for actors to use

[frosty heron]

Don't know how others do it, I am just hobbyist but I only have a couple of objects with things in it

Struct is unavoidable, and bp struct is broken anyway

if you are willing to go cpp there is easy way to add your struct in cpp. You can copy the bp header file and paste it in your cpp file

[grave apex]

would it be accessible in bp?

[frosty heron]

yes

[grave apex]

ah!

[frosty heron]

so you declare it in cpp and the rest is business as usual

[thin panther]

You'd need to add BlueprintType in the parentheses of that USTRUCT() tho, unless they fixed that one

[frosty heron]

I think it adds EditDefaultsOnly for component. is that bad?

gonna check on my proj

[thin panther]

EditDefaultsOnly is the bad one

[frosty heron]

Ahh

[thin panther]

Though you wouldn't have component pointers in a struct

[thin panther]

misspoke there.

Never use Edit on a component pointer

Change it to it's Visible version

[frosty heron]

it does add the BlueprintType. I'm on 5.1 for reference

[thin panther]

sweet

[frosty heron]

@grave apex TSoftObjectPtr<UWorld> Level;
Incase you are wondering what to write. The header preview not gonna help you for this case since you can't get a ref to the world in bp afaik

[deft solstice]

I'm new to UE and racking my brain to figure this out: On the thirdperson template I'm trying to use blueprints to do the following: For example when i press the 'Q' key for example, the bone of Quinn skeletal mesh named 'lowerarm_l' gradually rotates up 45 degrees over 1 second, when I release Q, It gradually rotates down 45 degrees, back to the original position. I've tried with the event graph of the bp_TPCharacter but I can't find any way to set the bone rotation. Otherwise in the animblueprint I can't get the Q key pressed event. Hope anybody can point me in the right direction 🙂

[main lake]

Is it a good practice in terms of performance to have alot of Actor components on an actor (on the BP_Character in this case) or is it bad ? Like for instance, if I have some variables being Health and Mana, could I create 2 actors component to put on the BP_Character with 1 of them handling health, and the other Mana or should I group both in 1 actor component ?

I'm asking this mainly from a practical aspect POV where if I create a modular system where you can disable the health system individually and mana indivually by just checking a checkbox somewhere.

[lofty rapids]

this is a c++ struct ?

[pale imp]

Anyone know how I could make the borders between colours more gradual, like a dithering effect ?

[frosty heron]

It's a header file you can view in your bp struct (Unreal Engine 5)
This picture is my struct

One can copy the blueprint struct header file if they don't want to write it them self

[frosty heron]

UI or 3D material?

[pale imp]

Post processing

[undone bluff]

sounds kinda like kuwahara?

[pale imp]

nah not kuwahara, posterization

[undone bluff]

ah

[pale imp]

I just want to limit the amount of colours on screen, but it has these ugly bands

[gentle urchin]

I'd normally not separate health and mana , but generally modularity through composition is a common strategy. It also helps for compile times 🙂

[pale imp]

is there a way to just limit the colours on screen to a colour palette ?

[undone bluff]

I'd make sure they don't tick in the class defaults

[gentle urchin]

Unless you need the tick

[undone bluff]

well not much to do with the tick in health and mana, at least nothing I can think of

[gentle urchin]

Nah it would mostly be a UI thing if you wanted to interp displayed health etc

[main lake]

So having 100 components on my BP_Character is fine ? 👀

[undone bluff]

I researched this at one point and pretty sure it's no big deal

[gentle urchin]

not a strategy I personally use, but if it makes sense, it makes sense

[undone bluff]

my main concern is keeping it organized, rather

[main lake]

What strategy would you use ?

[gentle urchin]

I could hardly think of more than 20~components to even make for a char but that's me 😄

[undone bluff]

I wonder if there's any downside to adding the components at runtime

[main lake]

Makes sense.

[main lake]

Yeah I just thought about that right now, I think it would be better to add them at runtime rather than having them directly on the character and being dormant

[gentle urchin]

I mean, I make components when it's something I'm gonna re-use,

but im not making every single reusable thing into its own component

[main lake]

so what's the factor that makes you go for component or not ?

[undone bluff]

I think systems and abilities should not go in the player character personally

[frosty heron]

modularity?

[undone bluff]

I'm learning GAS atm

so that should help

[gentle urchin]

GAS is a deep dive

atleast for my skill level xD

[main lake]

so on what it should go ?

[main lake]

same

[frosty heron]

must be easy for you 🐱

[undone bluff]

I mean the character itself, a character usually does a lot, so much that it can be overwhelming

I think it's important to split things up

[gentle urchin]

I tend to put systems into components...

Quest, Talents, Inventory, Radar ..

[main lake]

but you didn't say where you put it 😄

[main lake]

Yeah that's what I'm trying to learn to do 😄

[undone bluff]

components, on the character or controller

[gentle urchin]

I try to design them so that they do the common stuff, while still allowing for per project adaptation for the things that project spesific

[undone bluff]

when something involves interacting with another actor I try to keep that logic in that actor as much as possible

[gentle urchin]

so that i can use them across other projects

Interaction can be either component or interface , depending on if you need some statefullness to it I guess

encapsulation is good practice, keeps the code clean

[undone bluff]

both is good

depends on what kind of system

[gentle urchin]

avoid editing variables directly in BP A from BP B

Variables should be private by default ^^

[main lake]

Also another question more related to the editor than BP, how do you make the current editor preferences and project settings be the default settings for every new project you create ?

[vale pine]

Is there a way to mark an actor as "dirty" or something when using a "Call In Editor" function?
I've got this button that will change component properties on several actors, but the changes don't save unless I drag the actors around a little.

[undone bluff]

project settings are a config ini

I assume you have to change it in the template project

https://docs.unrealengine.com/5.3/en-US/converting-a-project-to-an-unreal-engine-template/

maybe there is some easier way I don't know about but this is one way to go about it

[cobalt gulch]

It is showing the print text yeah

[frosty heron]

that doesn't show anything

you can also get the return value, it will return false if it failed to salve (due to save game object not being valid)

haven't show me where you create and set the save game object either

so pretty sure that's the issue

[cobalt gulch]

Is this not the create save game?

Oh like this right?

[frosty heron]

Don't forget to chose your save game class

You also need to set the save game object when you load

Just get the return value from Load and set it to your save variable

[cobalt gulch]

like this?

[chilly plover]

Whats a good font for main menu's such as new game

[steady night]

if interact actor is a parent class

all subclasses will respond that that also right :/

[frosty heron]

no

also you are not even comparing classes

you are comparing an actual actor reference

[steady night]

ah true

[frosty heron]

even if they share the same class u will still get false if they are not the same actor in the world

[steady night]

hmmm

[cobalt gulch]

@frosty heron it always prints false and doesn't save the game properly

[frosty heron]

show latest code

[lofty rapids]

i'm finally making a blueprint function library in c++, i can say for sure when it comes to loops if you want a large one you need c

major performance boost 10x the speed

[frosty heron]

check your save game folder

does slot (the string variable) have value?

[wanton radish]

do I need to call SetMassOverride every frame? it doesn't work for some reason.

[cobalt gulch]

no saves

[frosty heron]

is "save" your save game class? if not changed it to your class

see if that's the problem

Create Save game Object -> Cast -> Set your variable

then save game to slot

Also again, check if Slot (the string) is not Empty

could be creating a file with empty name

it has a issue with casting twice

[frosty heron]

yea nvm, no need to cast

no point casting to it self

Is there a function in BP to return the real world date and time in a string?

[frosty heron]

Now node?

prob return your windows time and date tho

[frosty heron]

Check your slot string variable, does it even have a value?

@chilly plover returns the local date/time of your computer

[chilly plover]

Thanks a lot

Can I get it as a string to use append?
