[frosty heron]

I know we are just saying, you can't convert a single player project to mp

i mean you can but u will rewrite everything

[edgy ginkgo]

that is good to know for sure

[thin panther]

touche :P

[edgy ginkgo]

thanks for all you guys' help btw I appreciate it

I've been at unreal for only around 6 months so far

so it has really helped me find my footing

[frosty heron]

I don't think we helped you, I'm not sure what the bool does. But if you have specific question, maybe we can suggest ways to do it

[edgy ginkgo]

oh I mean I solved that issue so no worries

[frosty heron]

For example if you need to untick a series of bools, I would use array for that

[hazy rover]

Trying to use the Epic Zen Garden projects cherry blossom trees but even in its own showcase the blossom leaves are gone. then when I create a new level and place the branch the blossom leaves appear. any Ideas what could cause something like this? really want to use these for my project

messed with mip maps, LOD's, opacity... cant figure it out and I'm a bit new

[ocean gate]

I'm trying to activate an actor from a public set which is populated from within the level editor but for some reason this refuses to output anything from the for loop? The print is completely empty and the cast to broken_vent fails as well. Any ideas?

my bad I fixed it, I just didn't know what a "set" type was lol. Just use an array and it works fine

[naive stag]

hi guys! is there a way to trigger a custom event or a key press on an actor when not possesing it? i have an action set up on a keypress on my character but i need to debug something on it and i have to be on the observer screen (F8) but i don't know how to trigger the action when not possessing the player

[zealous moth]

use the player controller

[storm bane]

hello, im trying to get point lights to blink on and off until disabled but the code only effects the last light in the array for whatever reason. at first i thought it was the timeline that was to blame so i took it out and did it manually with set intensity and delays but it still has the same problem. any ideas as to why?

[naive stag]

a bit more specific please? a very big noob on this side of the keyboard 😄

[zealous moth]

you can set inputs in pawns but ultimately they need a controller because the controller interprets them.
you can also skip the pawn entirely and set your inputs in your controller

[zealous moth]

delays in loops breaks loops

instead use a timer

@lunar sleet beat you to it 😛

[lunar sleet]

lol and also manual loop within a loop like wtf

[storm bane]

ah cmon now

[lunar sleet]

I was actually gonna say shit looks broken af, fix it 😄

[storm bane]

i had to try something

[lunar sleet]

points for effort. now try something less hacky 😄

[storm bane]

man if i could hack it this shitd be workin lmao

[zealous moth]

noodle goes into meat ball and loops... how you gonna eat that spagetthi?

[storm bane]

is there a way to get a for each loop to work with a timeline? itd be a lot more compact

[split rose]

hey quick question for loading a save and changing levels do i change level first then load or the other way around

[zealous moth]

???? you want blinking, no?

[zealous moth]

what are you trying to do sequentially? because it depends

[split rose]

i just load a level, then i want to update the player pos

when the event is called

https://blueprintue.com/blueprint/43e2fvdr/

[zealous moth]

that shoudl be fine

[storm bane]

yea, i originally had it set up in a timeline that would go through the pattern i wanted and use the float output to control a single set intensity which is very simple but it only seems to want to effect the last point light in the array, which is the same problem the overly complex code i showed earlier had

[zealous moth]

use a timer @storm bane

[split rose]

odd it doesnt seem to open the level then

[zealous moth]

I usually don't open level by soft object ptr, i just open level and put my string

[split rose]

Ah this is why "Accessed None trying to read property K2Node_DynamicCast_AsBP_Main_Game_Instance".

[storm bane]

got any recommended resources for a noob to learn timers? i looked at their documentation but it brought in a bunch of other junk so something simple would be nice

[zealous moth]

ohhhhhh wrong game instance in the settings?

[split rose]

probably

[zealous moth]

https://www.youtube.com/watch?v=qc5WpNq7RFg&ab_channel=MathewWadstein

watch tomatoes

[split rose]

actually it isnt, hmm

[zealous moth]

what does it look like?

[split rose]

what part?

[zealous moth]

the cast

that failed

[split rose]

i believe it should work like that tho ?

https://blueprintue.com/blueprint/e8cu1cng/ this is my load function

im so confused ngl

[zealous moth]

oh

put your cast above too

[split rose]

ohh

[zealous moth]

you didn't cast to the continue game

[split rose]

bruh yeah

[zealous moth]

so you refer to something empty

[split rose]

thought itd be more efficient hahah

thank you so much

it works :D

[zealous moth]

👍

[desert bronze]

I have a a blueprint setting up some variable. I need to get that varaible reference in another blueprint. Am I being particularly dense that I'm not able to figure out how to get another actors variable?

[zealous moth]

use master class reference gets

https://www.youtube.com/watch?v=hOUdrom37-Q&ab_channel=PendingKill

[dark drum]

What are you trying to do?

[worn kestrel]

Hey there, i'm trying to make it so when "On Character Begin Overlap" is played it will continue to give points every second play until "On Actor End Overlap" is played. (I have heard of "set timer by event/function name" but not sure if this is where to implement it)
Right now it only gives me 1 the first time I enter and that's not optimal for what I have in mind. As you guys probably can figure out i'm kinda new to this so any help or redirection to a thread is helpful 😅 😄 (Posted this earlier and got some help, did not fully figure it out tho)

[lofty rapids]

probably set timer by event, and invalidate timer i think it's called

[worn kestrel]

okok, will have to google som more

[dark drum]

Ahh I get you. I don't think so. I've only been able to get it as a var type by promoting to variable which you won't be able to do with a BPI function.

[lilac hill]

I'm failing at casting for some reason. Any ideas?
The object reference is coming from a ray trace break hit result, hit actor

[zealous moth]

it means it hit something that isn't that

[lilac hill]

Yeah i just saw what i did wrong. I already removed the item and then did the casting. Silly

[pearl niche]

How do i get the BallOne mesh from Thirdpersoncharacter to be applied to Ball1 in this actor?

Essentially I just need either the TDCharacterBP or this actor BP to communicate what mesh is being used. I can work with it going either way, but i can only cast from TPchar

[blissful grail]

This is a convoluted way to do the same thing that GetAllActorsOfClass does

[zealous moth]

how would you do it otherwise?

[blissful grail]

Just use GetAllActorsOfClass

[zealous moth]

how would you specifically get that one actor?

[blissful grail]

Registering to a "master class" in this case is extra work for the sake of extra work

You can do the other stuff, sure.

It's the registering all of your actors to an array in your "master class" that is extra work for the sake of extra work

If you want a specific actor's variables, you get a reference to it. How you do it is context dependent.

[pearl niche]

Is there no way to pull mesh information between bps like cast -> 'get static mesh' -> Set material?

[blissful grail]

There are. What is your code?

You have to have a reference to a static mesh component before getting the static mesh inside of the component

Unless you have a function on said actor already that does it.

[pearl niche]

Essentially its just two balls that spin around the character. They trade meshes with things they touch. I have SpinningBallsBP that tells the balls to do everything so far and placed that under the character BP.

Now, I want the make it so when the player hits E the character mesh becomes a copy of one of the balls mesh'

but I cant seem to get the mesh information to go either direction. let me try to reference chain it again and show you the issue

[glass vale]

I created a very simple game only with blueprints in Unreal Engine 5.2. My project doesnt use c++ at all and it uses the metahuman plugin very extensively as a foundational piece.

I have tried to package my project many times so far and I keep getting the same thing:

fatal error LNK1120: 3 unresolved externals.

I am writing this because the issue I am having is way above my skill level.

So thats where you brilliant minds come in. I have had no success using google, youtube, chatgpt, bard, claude to solve this rather complicated problem

Here is the problem in detail. I would greatly appreciate for any help, tips, guidance you can give me on this. You are the only resort I have left.

Upon closer investigation of the complete log that you can find here:
https://docs.google.com/document/d/1uzlvysUKktsgIxPKc0dJ_DkeEPRTKI3VUPcV6BgIxRQ/edit?fbclid=IwAR32eN1joDECjw_vYH4ny3PT5DYdDxwu8ZQWXraObaeg8gWkMVa7cpKWSPU

I discovered these lines:

FaceMeshSolve.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

FaceTracking.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

PCARigCreator.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

VertexWeights.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

solver_utils.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

string_functions.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

fatal error LNK1120: 3 unresolved externals

After investigating all these errors further I discovered every single error has to do with the MetaHuman plugin.

followed in the comment

There is only one place online that someobdy had the same issue the way they resolved the problem is that they removed the metahuman plugin.

Except I can’t do that. My whole game is based on metahuman, everything. To remove metahuman for me is like trying the foundation of a house.

So I am trying to find a solution.

The best solution I found is this.

https://store.algosyntax.com/tutorials/unreal-engine/ue5-lnk2001-unresolved-external-symbol-solution/?fbclid=IwAR2BXFyaZqVNxGXp9b4RKSuBFpn6DNPGjrdA0nMeocnqO_UZ-aqDctNAsVo

So I have to do this, as mentioned in this article:

“LNK2001 error is thrown by Visual Studio Linker after the developer has attempted to inherit from or use a class that’s not in the module dependency list. It is a C++ Linker error meaning that the linker failed to find either the .cpp or .obj needed to link. The developer has to make sure to include all the modules containing the code that is referenced by his CPP files. Follow this simple step-by-step tutorial to solve it.”

Except I can’t do this. My whole project is using blueprints. I dont know how to code in c++.

Granted I can read c++ and make sense of some logic. I am good at following step by step instructions. But I can’t find any on this particular issue. And the article I mentioned above doesn’t really address my issue given my level of knowledge, skill and understanding in c++.

So thats where you brilliant minds come in. I have had no success using google, youtube, chatgpt, bard, claude to solve this rather complicated problem, way above my skill level. I need a way to solve the following problem:

need to ensure that the linker has access to the required modules containing the referenced code used within the MetaHuman plugin's code.

I would greatly appreciate for any help, tips, guidance you can give me on this. You are the only resort I have left.

Thank you so much for your attention and help!

feel free to private message me if you so desire thanks!

[flat coral]

#packaging

Or #metahumans maybe this could be an issue with that. #cpp for "why won't my CPP build" questions, they hate those but you'll get an answer

[glass vale]

thanks!

[flat coral]

I wouldn't go straight to #cpp though because it might not be a CPP build issue, it might be something more like "oh to use metahumans you also gotta turn this plugin on, or download this thing" type of answer

[zealous moth]

LNK error means that something is missing in the compiler

definitely a cpp issue

[glass vale]

not sure if you read what I wrote here:

need to ensure that the linker has access to the required modules containing the referenced code used within the MetaHuman plugin's code.

right, and these are the metahuman pieces that dont have that link:

FaceMeshSolve.cpp.obj : error LNK2001: unresolved external symbol __std_find_trivial_2

[blissful grail]

We only "hate" those questions when that is literally the only thing said and nothing else is provided.

[flat coral]

Haha I don't meant to give y'all a bad rap, I've been there asking those questions myself, I'm awful at C++. I just figure, based on the languages I am good at programming in, it's just nicer to be fielding interesting questions from fellow experts, rather than the most basic possible question from someone who doens't know what the fuck anything even means

[glass vale]

My whole project is in blueprint, i know nothing about c++ thats why i worked in blueprints. Its the metahuman that is using and not getting linked,

[blissful grail]

It's complaining about the std library. Which is weird to me. May just be an issue with the metahuman plugin. I've never used it personally though.

[opaque mauve]

can anybody guide me on how to use enum as a movement state?
i dont really know where to begin or how to set everything up
for example, i want to disable my sprint during ADS
can anybody guide me on how to start?

ive watched a tutorial
https://www.youtube.com/watch?v=hVcLWoQIDRM&t=320s

but he doesnt get into the detail much

i have everything setup, but i dont know how to start lol

any assistant would be much appreciated

im still having trouble understanding enum

most of the tutorial is mostly on items and class

not character movement

[pearl niche]

when i press E only my character gets the information, is there a way to make it so other actor bps react also?

[dreamy yacht]

Hey 2all! . Short question - I am trying to create a weapon for my combat racing game - some sort of scrap launcher, that fires randomly 1 of 3 pre programmed bullet types

I have created the bullet type array

But I cannot link it to set static mesh, I can't set static mesh input to integer no matter how hard i try

how to solve ?

[north lynx]

Ok, hear me out...
I'm working on Sanity mechanic. I want to build the opacity of the widget in time according to the Sanity level, and there's a catch...
On event tick I can do widget to check the sanity level, but I don't know how to remove the other widgets every tick so the Sanity Widget don't duplicate thousands of times

[dawn gazelle]

You create a variable of your enumerator type and that variable now acts as your state.
When you want to change your movement state, you change what is contained in that variable.
Anything that needs to know about the movement state should read that variable.
How and where that movement state changes needs to be based on your design of how you want your character to move, and you'd check the current movement state to see if the player is allowed to preform the actions you want.

In your example of wanting to disable sprinting while in ADS, you'd likely want to have another movement mode of "ADS" and set your movement mode to that when you've successfully started ADS.
When starting to sprint you'd need to check that the movement mode is in an acceptable movement mode for sprint to start before actually starting the sprint.

[stiff tendon]

scrap the for loop. Drag a pin from your 'BulletTypeActorsArray' (which should really be named StaticMeshArray, it's confusing :pp) and search for 'Random'. Plug that random node into the SetStaticMesh's NewMesh pin and that's it, it'll randomly select one of the three static meshes

[dreamy yacht]

Wonderful!

Thank you !

Just 1 more problem

[rough wing]

What does my path need to look like? This one I have does not work

[dreamy yacht]

When I do pre-set of the static mesh in options it works like a charm, using projectile movement

[opaque mauve]

does this seems about right?

[dreamy yacht]

But when I remove the pre-set bullet static mesh actor and leave it as random

the engine behaves like one of three bullets from array do not use the projectilemovement thingy

[opaque mauve]

what do you think? or do you have a much more efficient way of doing it?

[dreamy yacht]

and just fall flat on the ground

[opaque mauve]

ohh and also, how do i connect the enum to animation blueprint?

[faint pasture]

just dont add it again

tick -> set opacity

done

[cursive wigeon]

Hey does anyone know how to go about making a setup like the lightsaber construction mini game in jedi fallen order or whatever game? (Several custom parts uou can choose to make a new lightsaber) Or topics I should research?

[ashen gazelle]

I am following a tutorial using UE4 Engine Input but since they have been depricated, how to i add bindings with a scale now?

[faint pasture]

I mean just try to make a lightsaber actor with swappable sub-parts

[lunar mulch]

Strange question maybe, but i have a simple weapon sway code, and the sway values behaves very differently inside the Editor & Standalone-play then it does when i package the game. Inside the editor the effect is barely noticable, inside the packaged game it's very noticable.

What could cause the values to change so drastically when packaging the game? ( anything helps, just looking for directions where to look. Been at this for days.)

[silver garden]

Hey, does anyone knows an article, post, etc, that goes into the FPS sameple blueprints?
As a programmer, it confuses the heck out of me how that sample, its player and gun works/are tied together.

[lunar mulch]

Theres some pretty good FPS guides on youtube that give you a good start, theres a few series like this one: https://www.youtube.com/playlist?list=PLL0cLF8gjBprQbgS7HaBIsjgXQYEeG1zX that give you a decent insight on where to start.

Havent actually followed that one, but couldnt find the one i used so it serves as an example i guess :p

[lusty hedge]

how can i check to see if the users text input is == any of the enum commands

i want to make a system that checks if the users input is a certain command

and run code appropriately

[amber spindle]

Maybe someone could help with player movement. For some reason my player is not losing velocity while stopped moving. He is moving on the wall and mode is set to flying. While moving on ground it's all good. Orange numbers are velocity length

[silver garden]

Hey, thank you!
I'll check it out!

[thin panther]

You've just shown him losing it though? Because he slows to a stop?

[amber spindle]

ye it losing but too slow

[thin panther]

might wanna check your general friction/air resistance settings and see if they help

[amber spindle]

yep thats what I needed

Frictions settings already making a difference

[amber spindle]

is there a way to create friction settings for custom mevement modes?

cause there is no option for custom of flying mode

[dawn gazelle]

There's no good conversion from text to enumerator.
You can create a Map variable to map it, but you'd also probably want to convert the text to string so you can lowercase it all, while also using lowercase strings in your map.
In the end, you'd probably be better off just using string rather than an enumerator at all as you could then switch on string.

[thin panther]

you'd probably just want to set it when you change moves i imagine tbh

[lunar mulch]

Okay, so i didn't delete my Intermediate,Saved,Build folders before i packaged.. ^^

Lesson to self

[lilac hill]

Getting weird results from line tracing. it's returning both true and false hits on the landscape and other objects

[lunar sleet]

Maybe print the actual hit actor instead so you can see what’s going on

[lilac hill]

It's hitting landscape when it's hitting, when it's not hitting it's just false. The hits are correct, but i don't see why it also doesn't hit

[lunar sleet]

Probably the angle. Try increasing the distance on your end vector

[lilac hill]

No difference

Could it be something about the types? I've just put every type in there

[crisp gulch]

I'm trying to make the ship tilt slightly to the side when moving in that direction, but I can't seem to get the Add controller roll input node to affect anything. I tried entering a bunch of values in it and messing around with it with no results.

[unique cloud]

I'm spawning and updating the Mesh of a Character BP that both use the same animBP (male or female), the animation work for male only if the mesh is pre-set to male (same for female), their counter-part won't work if the other is set, both won't work if the mesh is set to None.. What can I do to "refresh" the ABP and have it work ?

[crisp gulch]

Okay, this is what I was able to come up with. Ends up I had to reference the mesh. The only problem now is that the tilting isn't smooth but instantaneous.

[unique cloud]

try FInterp Ease in Out node

[trim matrix]

im trying to find where in BP_Box_Truck is BP_BT_RearTire referenced

Cant find it there

[unique cloud]

If it's not in the parent classe juste save all and restart ue 🫠

[trim matrix]

yup

[trim matrix]

its because this asset has one Blueprint per car type

So im trying to use only one blueprint for all cars, makes sense right?

though the asset is super good

here you can see it has one bp for each car

and instead of changing the BP im changing the skeletal mesh only

though dont know if what im doing is good

Because they have one BP for each car for a reason. im trying to understand why

[unique cloud]

good question, maybe ask who ever made it to havve a better idea

[trim matrix]

its kind of weird to make one BP for each car

though cars are complicated

[unique cloud]

well it makes me thing of the issue I have right now, I'm updating the mesh as their are both using the same ABP but switching it kills the animation

[trim matrix]

can you post stuff to see if i can help?

[unique cloud]

that's literaly the only thing I'm doing, they both work with the ABP but not when switching, print string confirm its the right ABP set after the switch

I though of something dumb... trying..

tried directly with set skeletal mesh asset, no success

[unique cloud]

Is it really better to have only 1 bp for all? I'm thinking to switch my logic to have 1 BP per playable character at that point

[junior prairie]

Is there a bug where sometimes the Play Montage node just randomly doesn't work? I have a setup that plays a melee montage chosen from an array of montages, and each one has an anim notify that sets CanMelee to true towards the end to signal when the play should be allowed to punch again. I'll throw a hundred punches and it'll work fine and then randomly one of the anim montages won't play and I'll get stuck with CanMelee set to false and not being able to melee again

[trim matrix]

yeah, because its just one class, or even making inheritance

but its a quick simple game dont bother maybe

i maybe wont bother because its just a silly car game

so like if you have 6 cars, it sucks that you have to work on 6 bps, so the best is to make them a parent class and work there

inheritance is still confusing to me though

[lunar sleet]

Which part

[lunar sleet]

Whenever you can avoid duplicating code, do so. OOP allows you to make a base bp that handles shared behaviours and splitting things up from there using children bps, and you should make use of it whenever possible, not only to save yourself time but also to keep your code readable

[hazy dock]

So I'm getting this error when packaging. It seems to have something to do with the World Context pin, but that's as much as I can glean and I need help knowing where to even start with it:

I did have 2 functions in blueprint libraries that had "__WorldContext" input pins, but I got rid of them and I'm still getting the error... Not sure what else to look for/how to look for it.

[lunar sleet]

You should ask in #packaging

[lunar sleet]

Not afaik. Always assume it’s you and not the engine. You’ll need to debug your code to find out what exactly is happening that makes it not fire. If it’s intermittent use print strings at various points in the code until you narrow it down

[junior prairie]

Yeah I threw a bunch of print strings around and made sure I was setting CanMelee to true in each animation's anim notify as well as at the end of the montage, then I also printed the montage name before it gets played

the result was like 95% success but occasionally it would print the montage name and then nothing else, so that leads me to think the montage was not playing hence no print from the anim notify or from the montage completing

[lunar sleet]

May need to ask #animation about montages not playing at random

[iron wing]

can someone tell me why this won't work and how to fix it? I just keeps accessing none everytime

[hazy dock]

I did, no one seems to answer things there

since it was blueprint related I thought someone here may have an idea

[lunar sleet]

It’s a bit quieter so you might need to be patient for a while

[lunar sleet]

Can’t rly offer much on the bp side other than debug to find the precise thing that is not firing

And it seems maybe you’ve found that already

[dawn gazelle]

Access None indicates you're attempting to use a reference variable that has no value set in it. I can only assume based on what I'm seeing that the accessed none is on the "Player Ref" variable in your Options Menu widget?

[iron wing]

yeah

[hazy dock]

fair enough, thanks anyways, hopefully someone will notice me in packaging while I keep digging^^

[dawn gazelle]

Ok, so that means you've probably created a variable of the type of BP_Player, but you haven't set a value into it. To do that you need the reference to the player and set it in to that variable. An example of how to do this would be on construct of your widget to "Get Owning Player Pawn" and cast that to BP_Player and then set it into "Player Ref".

[iron wing]

yes that work out perfectly thank you very much

👍

[wicked marten]

wanna ask who can i hire to fix UI BP forme

[tawny jackal]

What would be the best way to store extensive player statistics, including things I would want safe and usable for multiplayer competition?

[dawn gazelle]

external database and also only using dedicated servers that you are in control of (ie. not making it possible for players to send any kind of updates to those statistics)
Anything else could result in players spoofing data, not only for themselves, but for any players.

I'm trying to set up a waypoint system. I have a series of BPs I'm using AI Move To to target. I figure I'll Get All Actors of Class to target those BPs. I'll probably do a For Each Loop and maybe once a waypoint is reached, I'll turn it off. The question is, how should I specify that first waypoint?

[frosty heron]

@trim matrix

[trim matrix]

So I created 2 render textures attached to 2 scene captures in my player character, my character's actual camera called "masterCam" has the post process blendable of the Anaglyph Mat in the first image, but I dont see any difference when I run my game?

Technically the material AnaglyphMat is working since I added the material to an ingame plane object , so i dont know why it isnt working as the post process blendable

[frosty heron]

put something on him or at least censor it

[short zephyr]

Is it possible to build an entire game using only blueprint?

[dawn gazelle]

Depends on the game.

[lunar sleet]

This #blueprint message and also you’re in the wrong channel, try #materials

[gaunt dawn]

I'm looking for a tip. I'm making a rideable rail system in TPP project. I made a cart that moves on a spline using timeline going from 0 to 1 and SetWorldLocationAndRotation. But when player gets on it's jittery. Right now I think about attaching player to cart when he gets on, but maybe one of you could propose something simpler/better? Link to video (google drive, so there is streaming, no need to download): https://drive.google.com/file/d/1ragr4M6Mt7dyMDUfaJloKOY2x5KeQL8D/view?usp=sharing

What would cause some static meshes to be not working for Only Owner See?
I have two weapons. One works perfect and is hidden from other clients and is only shown to the owner, but my second weapon is shown to everyone.

It's not being set at runtime, I've got the mesh enabled for Owner No See by default in the Static Mesh component of the character.

This happens on singleplayer as well Not a replication issue or anything.

[distant hollow]

Can someone guide me how to change from one to the other?

Guys can you say why my Sphere trace is not following the sockets of the sword but its like it follows the character ?

[nimble wasp]

How do I access a variable stored in my level blueprint?

[mental trellis]

With great difficulty.

Don't use level bps.

[dark drum]

I'm not aware of any way to do this. The level BP is one way as far as im aware.

[nimble wasp]

Should I use a game instance then? I basically need to store a variable somewhere independent.

[dark drum]

That would depend on what your actually trying to do. Whats the var for?

[nimble wasp]

I've got a resource that goes up when an enemy is killed. When that resource reaches a certain number, it can be spent on an upgrade.

On the death of the enemy, I can increment it - but the thing to be upgraded isn't always around. Nor is the enemy.

[dark drum]

Would anyone know how I could improve this? It's find the look at yaw between it's start and end actors and clamps the yaw to the desired angle. It works but I have an issue where is the start actor is rotated at 45 degrees I get an issue where the direction vector flips between negative/positive depending on which side of the center the target is standing on (the player).

Hopefully that makes sense lol.

[dark drum]

If it's specific to the player you could store it on the player character, player controller or game state. Personally, I would make an actor component that managers the players resources that can be placed on the player character (or game state depending on the end goal). This way you can get the component from the player character or game state easily.

[worn kestrel]

Hey there. Im making a KOTH gamemode right now and have made some basic BP on how long a person is in a zone.
I want it to keep counting up everytime they enter. Right now it only works the first time someone enters. If they leave and come back in, the loop has stopped and they are only granted one point. How would I solve this? Thanks in advance for any help or guidence 😄

[dark drum]

When the player enters the trigger, check if the timer is valid, if not, start it again.

[worn kestrel]

appreciated the help 🙂

[magic crown]

Any ideas on this one please? thanks

[narrow stratus]

Our new action mapping doesn't get included in the build, it only uses the old mapping

[pastel maple]

is it possible to make a sequence not work in order?

[thin panther]

That would kind of defeat the purpose of a sequence.

But in general, yes accidentally. If a branch has an asynchronous action it will not wait for it to complete

[fathom vigil]

this is in my animation bp can someone tell me why this doesnt work. When I press shift my max walk speed gets set to 800 from 600 til I release. If I set it to 600 its always true and it works but if its not it doesnt

[thin cradle]

I have a mesh component A with a specific scale and a child component B with a specific position, rotation and scale
when changing the scale on one axis on component A, the wrong axis gets scaled on component B
How would one fix this?

[dark drum]

It's scaling the mesh on the correct axis, it's just your mesh isn't orientated correctly. You would need to rotate the mesh in your modelling software so it points along the correct axis and reimport.

[thin cradle]

this is a default unreal cone

so if I want to reuse any mesh in multiple objects I need to make a slightly rotated copy of each of them in my DCC every time? and presumably can't dynamically move any child mesh around at runtime then?

there's gotta be a better way

like, iirc unity just properly transforms the scaling on child objects, and I saw a post saying unreal did this before 5 too

[dark drum]

You'll need to make your own cone then. You can export it as an FBX, import into your 3d modelling software and rotate accordingly. Alternatively, I know unreal has some experiment modelling plugin so you might be able to do it in the editor.

[dark drum]

If you scale the parent on the X the child also gets scaled on the X. This is irrelevant of the rotation you've applied to the child.

[thin cradle]

yes I understand, what I'm saying is Unity and apparently UE4 did it differently

instead of requiring peoples to open blender or whatever and make a bunch of copies of the same mesh

[lime basin]

so if I want to use this actor in animation blueprint i need to make sure this thing is set correct? because by default it wasnt and i was getting null all the time when i was trying to initialize variable

im still getting used to ue5 such a noob question

[thin cradle]

like I can't imagine why anyone would want scale to be solved like that, and it's afaik relatively basic transform math to figure out the proper position, rotation and scale of the childs relative to the parent

I'd be baffled if there isn't some option somewhere to change this behaviour

[dusty hazel]

Hi everyone, been trying to look for a solution for months to no avail...

BP works fine but I'm getting the dreaded "accessed none, getplayer controller error"

This is in the level bp

Any light shed greatly appreciated

[frosty heron]

Means you don't have valid controller at the time of accessing it

Also avoid lvl bp

[dark drum]

The way it works makes perfect sense. You scale on the X so all the other children also get scaled on the X. Making it take into account the rotation would mean it would have to scale on the Y or Z depending how it's rotated. This is less intuitive. It's only an issue because you've rotated the child mesh of which the fix is very simple, just import a new mesh that is already aligned along the axis you whish it to be so you don't need to rotate it.

[thin cradle]

it's how practically every other 3D software work

and the fix is not simple it's making a copy of the same mesh and reimporting it every time I wanna move a child element around

if you're one of the team members that don't know how to use external 3D software you just can't do anything

it's seemingly how UE has worked until 5 too

[dark drum]

It's re-importing when you want the mesh aligned along a different axis. Another option is to not have it as a child and use the construction script to update the scale based on what you want the original parent to be.

[thin cradle]

that "when" could be dozens of times a day and now I have a bunch of duplicates of the same mesh in my assets

& we've had other problems with construction scripts being pretty unreliable for actors placed in a level and not always rerunning when the original blueprint was modified

• having to setup that custom math for I guess every single actor in our game in order for it to work like one who's used other DCC, or unity, or previous version of unreal would expect

like there's gotta be some hidden option somewhere, 90% of the time for weird stuff like this there is

especially since this is the kind of change that'd break porting projects from UE4 to 5

[dark drum]

As far as im aware, it's been this way since UE4.

[lime basin]

i dont get it why is this failing i cant cast to my actor blueprint

[dark drum]

Does your bow skeletal mesh use the same skeleton as the player characters skeletal mesh?

[lime basin]

no i made a new one with code

[dark drum]

Then the bow skeletal mesh would need to have its own animBP. An animBP is only for a specific skeleton.

[lime basin]

this will make it more complicated to connect animations

im still learning ue5

but you just gave me a good starting point thank you men @dark drum i didnt know this! i will figure it out

[lilac hill]

Anyone know why Line Trace returns both true and false on hits?

[dark drum]

I'm going to assume this is on the character BP and called on tick so your most likely have another character somewhere which is giving the other result.

[lilac hill]

dang, that is actually spot on

[wicked cairn]

Hello!! I asked this in #pcg-framework but I'm unsure If it were the right place to ask, so just incase;

I'm making a game where Players start at point A and find their way to point B, but would like the map to procedurally generate the path between the two points each time it's loaded!

Any idea on how I'd approach this? I'd be using sets of tiles that the map can place together. (Ex. Players spawn at point A in a Forest map and will traverse the procedurally laid out paths to find their way to point B) Any tutorial links or guidance is appreciated!!!
(please excuse the silly mouse drawn examples ;u;)

[dark drum]

I've done the same thing enough times I've learnt to spot it haha

[lilac hill]

So how would i solve that? I want to show and hide a HUD element based on what the character is looking at

[dark drum]

Check if the character is locally controlled would probably do it.

[lilac hill]

Allright, thank you! I'll dive into it

[dark drum]

I've not used PCG but I would have a BP that generates connected tiles with the entrances and exits and then have a PCG component for generating the tile based on the entrances and exits.

[dusty hazel]

Cheers for responding!!

But can you change cameras outside of level bp?

[dark drum]

What are you trying to do with the cameras?

[dusty hazel]

Switching cameras during run-time

[dark drum]

Yea you can switch cameras outside the level BP. Are you doing fixed cameras?

[dusty hazel]

Ohh I didn't know that, thanks...

Yesss, 3 fixed cameras!

Although I'd like the flexibility to move them

[dark drum]

Well as luck would have it, I recently uploaded a tutorial for a fixed camera system where you can choose to have it move along a track. Check it out, you might find it useful.

https://youtu.be/RctV_1MGuP4

[dusty hazel]

You're a boss! Cheers

[waxen gull]

how can i achive similar behaviour that i get with AI Move To, but for a pawn controlled by a player controller?

[versed sun]

i believe:

[waxen gull]

that kind of just teleports my player

yea

just teleports it

oh nvm

you have to enable this

on floating pawn movement component

[waxen gull]

thx

[dark drum]

Adding to what Ryck0Shae said, when using the simple move to location for the player character, if you need to know when the character gets to the location, you can create a BP with a sphere collision capsule that you spawn at the desired location and have it trigger an event dispatcher when it's overlapped by it's desired target (the player character). That way when you spawn the marker, you can bind to the event dispatcher and have something happen when the player gets there.

For the one i made for this purpose, I also have it auto destroy itself when it's been reached so you don't have to worry about doing it afterwards in another BP.

[waxen gull]

thx

[narrow stratus]

maybe some more information, the editor uses the defaultinput.ini, but it looks like the build uses input.ini, but this one doesn't get updated

[north lynx]

Is there a way to update the sound volume in time?

That the sound is playing along all the gameplay but it will be higher volume and lower volume when I change it

[worn kestrel]

Hey there. Im making a KOTH gamemode right now and have made some basic BP on how long a person is in a zone.
I want it to keep counting up everytime they enter. Right now it only works the first time someone enters. If they leave and come back in, the loop has stopped and they are only granted one point. How would I solve this? Thanks in advance for any help or guidence. (I wrote about this earlier and got a tip about is timer valid. Where should I implement this?)

[dark drum]

I believe you would need to use an audio component to have that sort of control. The play sound node is fire and forget.

[dark drum]

As i mentioned earlier, check if the timer is valid when they enter the zone. (OnOverlap) If not, start the timer again.

[lofty rapids]

you probably don't want to set to clear the timer, but get and clear the timer.
but also i'm not sure your event that fires every second will work correctly, it's pulling from other actor of the overlap, not sure what that data will be when no overlap and just firing like that

[zealous fog]

Im making an editor Utility widget. Anyone have any idea why this will only fire off on my third mouse button ? (I got 2 buttons on the side of my mouse, and it only works with one of those?) Left/Right mouse click works fine in rest of editor

[lofty rapids]

you most likely want to set the timer on begin overlap, so it runs when you overlap, then invalidate on end overlap, not sure you want to use begin play like that

[worn kestrel]

Not sure either, new to this so im just trying until it works😅

But thanks to you both! Will continue to try around with the info! 😄

[lofty rapids]

i'm fairly new as well learned a bit, but your timer in the begin play looks incorrect.

[north lynx]

Ok, that makes sense

[north lynx]

But how to create audio component? And set it properly?

[worn kestrel]

Haha, just changed it up like this and now everything I wanted works. Was just the begin play that really screwed it up.

[lofty rapids]

the only thing i would say is you keep casting and pulling from other actor, you can probably just check on overlap, set the timer because you already know it was the character you want, run the timer, and invalidate after. And also your using set again instead of get which might be odd.

[dark drum]

Something like this would probably be better.

[worn kestrel]

Ohhh wow okay. Will try it out! Thank you both for taking your time. Super kind. ❤️

[frosty heron]

You can create sound class for each group

Master -> BGM -> voice -> sfx. Etc

Then you will push push modifier to change a group volume

There is youtube tutorial for this

[lofty rapids]

simple version, you were close just had a few things mixed up

[worn kestrel]

Big thanks to both for putting in so much time in such a simple thing!

[lofty rapids]

the other is probably better in ways i'm still learning, i just like like to help if i can

[north lynx]

Can you send me a link? I can't find it

[distant hollow]

How do I draw a line and make sure it runs straight along an axis?

[ancient folio]

Hey all, is there possibility to check if actor is hitted by other actor? Let's say one actor is constantly hitting another actor, but I want if hitted actor know when it is not hitted anymore?

[distant hollow]

You can use a End Overlap and check the actors

If you want to filter out specific actors, you can try using Tags

[fallen glade]

I'm getting horrible results when trying to offset spline meshes along a curve, convex points are fine but concaves are wrong because the points end up intersectiong each other. Does anyone know if there is an easy way to get around this?

[dark drum]

What are you trying to do?

[spare pike]

I am getting really fed up with the perception system, why can't these pawns hear each others noise events? It's the very same setup as on my players character, which they can hear perfectly. They have stimulisource just like my players does, their hearing is set to all affiliations yet it refuses to fire.

https://litter.catbox.moe/28ity9.mp4

[dark drum]

Are you calling the make noise node (something along those lines) when you're wanting them to make a noise to hear?

[naive stag]

any ideea how i can constrain 2 actors at runtime? i have a fishing rod and a fish and i want to create a physical constraint when "hooked" but it seems that the constraint i'm creating has no effect on the fish. Here is how i'm creating it and attaching to the components

[mild basin]

I am trying to create a widget blueprint that plays a video, the video portion is working, but when setting the media player for the audio component the video itself stops playback altogether and no sound plays.
https://blueprintue.com/blueprint/vq_th_7b/

Best as I can tell this is how it's supposed to be done and is how it is done in many tutorials, it doesn't however seem to be working here.

TIA for any assistance.

[faint pasture]

Show the component hierarchy for both actors

[naive stag]

these are the two actors

[spare pike]

i'm a bit too far in to make that kind of mistake, no i AM calling a noise event

[faint pasture]

is the fish's Capsule Component simulating physics? Why is the fish a character?

What you have right now is a constraint between 2 characters

if they are both not simulating physics then it'll do nothing

the CMC is not physcis

[naive stag]

the fish is not simulating physics, they are controlled by AI

if i enable physics on them they stop walking and go rolling around

so, no physics, no constraint, got it

[dark drum]

Ok, and how do you have the hearing setup on the AI?

Edit: also you'd be surprised how a small mistake can set you back hours, especially when you're tired. 😉

[spare pike]

the thing is that it works for the player character perfectly, they just refuse to acknoweldge their co-workers. I understand the sentiment but i need teamwork.

[spare pike]

well i just restarted the engine(again) removed and replaced the actors with the same settings and now it just works.🫠

[dark drum]

Typical UE lol. At least it's working.

[fallen glade]

I was trying to make a cart decal, I resolved it in the end by extruding the spline by 10 units each time in a loop and removing/merging points that got too close together, bit of a hack but it works for what it is

[sturdy notch]

Anyone aware of what settings might cause decals to stop spawning properly? I don't recall changing anything but now if I call multiple decals (bullet holes) from a loop, only 2 of them spawn in. I don't get this behavior in other projects or if spawning in other types of objects - just decals.

[charred berry]

5.3 images of splines are Maggie no attempted fix from details panel is helping,,known issue ?

Using add spline feom ue not bep as such so wasn’t sure where to post

Not from bp

They are fixing some cracks near control points which I have but not related fail

[spark steppe]

https://tenor.com/view/bunnies-what-confused-meh-gif-12007368131756137942

[dark drum]

Show how you spawn them.

[sturdy notch]

The spawning doesn't appear to be the issue as I can spawn other objects fine. There's a bug in the spawning of multiple decals. It works fine, using the same code, in other projects and on different version of the engine. I just, for the life of me, think of what would've changed to not spawn them correctly in my project - some setting buried somewhere, perhaps.

[dark drum]

Unless you show how you spawn them it's difficult to say.

[flat coral]

Okay I've got this function that tests several structs to see if they're valid, and updates a boolean if they are. Except, I've just proven that even if they're valid, it still isn't updating the damn structs, I test afterwards and it's still set to invalid. What the heck!

[elder lodge]

have you stepped through it with a breakpoint?

maybe a later result overwrites the first result

[dawn gazelle]

If I remember right, the loop returns a copy of the structure data, not a reference, so I don't think you can't really use set members by ref.

[flat coral]

Shit.

[elder lodge]

womp womp

[dawn gazelle]

You can use a Get by ref from the array and use the array index from the loop

[undone thistle]

Hey, I can't seem to open doors In the map I just bought

Here is the blueprint, does anyone know what I need to do?

[elder lodge]

reach out to whoever made it
we can't diagnose the whole asset based on just the bp

[flat coral]

Minor ew. Let's see if it works.

Yep. Thanks!

[elder lodge]

also if you're doing a check for Validity in any of the list, would you want to use a for break loop?

[sturdy notch]

The code worked as expected until it just, didn't.

It spawns only 2 - but shows all 8 line traces firing. If I change the Spawn Decal node for a Spawn Actor from Class node, all 8 actors are spawned.

[flat coral]

Nah, because the goal is to update the status of every item in the list. One being valid is actually enough in some cases, but I leave that to other BPs interpreting this data

[dawn gazelle]

Your issue stems from:

1. Sending multiple RPCs in one frame (having the loop run on the client)
2. Sending multiple multicasts in one frame (from having the loop calling the multicast multiple times)
3. Sending hit results in a multicast - hit results have a lot of data in them. If you're only using the two fields from the hit result, then modify the multicast to send only those two values.

Instead....

1. Send one RPC from the client to the server.
2. Have the server loop and aggregate the two values you want from the hit result in an array of a custom structure that has two vectors.
3. Send ONE multicast on completion of the loop with the array you've constructed.
4. On the multicast event, again loop through the custom structure array and use the values as you want to spawn the decals.

[sturdy notch]

I'll give that a go. It's just odd that it does work in other projects, but I agree that it's probably more performant going your route.

[dark drum]

It's most likely a case that some of your traces don't hit anything. They will most likely be at 0,0,0.

[sturdy notch]

Then why does it work if I spawn actors instead? All the line traces (with debugging enabled) hit as intended.

I like the elegance of the other solution, and will do that moving forward, but don't think it rectifies the issue.

[dusk atlas]

Are blueprints innately less performant/any different than similarly functioning code?

Any highly competitive, fast paced multiplayer games using blueprints, for example? Is there no downside?

[faint pasture]

100-1000x slower

depending

but whether or not that matters, also depends

[dawn gazelle]

They are less performant as they run on a VM instance, so yes, anything you do in blueprint would technically run faster in C++.
That said, sometimes the performance gains are minimal, and you don't necessarily want to do everything in C++ as it's just easier to do in blueprints.
If you're going to do multiplayer, you will more than likely need to dive into some C++ in some way or another anyway.

Rule of thumb is, if you want to prototype in blueprint, nothing wrong with that. Profile your game, identify any problem code that could benefit to be running in C++, then convert those bits to C++.

[faint pasture]

The tighter and hotter the loop, the worse it is to run in BP.
Open door event, thats fine in BP.
Block building system like Minecraft? Probably do it in C++.

[bleak merlin]

Pretty sure this is just me being dumb but quick question. I have started messing around with an isometric-esque view (can't truly do isometric in unreal due to lighting apparently). I am using the third-person template and just changed the FOV and perspective and how far away the spring arm is. I am trying to make a smooth rotate and zoom in/out but due to trigonometry and the way the camera boom works I am having trouble. I have tried messing with just the x/y positions of the camera and changing the spring arm length and the offset all that give varying degrees of success but none of them are game ready. Is there a tried and true method for zooming in with a camera that I am overlooking?

[lofty rapids]

setting the arm length i would guess should would

is it just to jittery ?

or it's not working at all ?

[narrow pendant]

when spawning a force feedback component, am I supposed to destroy it, too? does it auto destroy itself when it finishes playing?

"this is a fire and forget effect" - means I don't have to deal with anything after spawning it I assume

[bleak merlin]

I will post some screenshots or see if I can make a video to show.

[plush ether]

Hey everyone, I'm working on an editor tool and for that tool I will need to know the bound of the current terrain (X and Y)
What I found so far is this

But the print give me really big values

LogBlueprintUserMessages: [BP_WorldBuilder_C_2] X = 63000.0Y = 63000.0

And to validate I tested with a cube and those are my result

The cube is by far bigger than the terrain value I get

[honest wraith]

I think box extent refers to from the origin, how far out from either side should it be

If you want to test it working, try getting the actor 3D scale

[plush ether]

Thanks, I try but unfortunately I get the scale X Y of the terrain which are 100 each

[honest wraith]

Is the bounds pretty much half what you'd expect?

[plush ether]

No I expected that too but its still massively larger

[honest wraith]

Cause I'm fairly sure if you had a 1mx1mx1m cube, it'd return 0.5 units

Could it be affected by the scale?

[plush ether]

But I think you got it (mostly)

I do a quick test and I give the formula

The terrain scale is 100 and the bound I have is 63 000

I have to do 63 000 / 100 * 2 and that give me exactly the right size

In that case 1260

So divided by 50 if you want to save a step

But I suspect its affected by the number of ocmponents and all

Well I tested on other terrain setting and the result still work

So its bound / 50

Thanks for the help 🙂

[honest wraith]

You're very welcome 🙂

[rugged lion]

does anyone know how to make a "box collision" not a part of the player. Im trying to use the box colission to deal damage to another player when it recieves damage then it also hits the player

[bleak merlin]

what do you mean by not a part of the player?

[rugged lion]

when the box collision recieves damage so does the player

[bleak merlin]

make a actor bp that has box collision and use the collision to detect what player and then add damage to that actor/player. If you gave a scenario of what you are talking about it makes it easier to understand the end goal

[rugged lion]

im trying to get a "flashlight" to do damage to a "ghost" and im using the box collision as a way of detecting whether the ghost is within the flashlight, and if the player gets to close to the ghost then the player dies. So now when the flashlight shines on the ghost to deal damage, the player dies. I am also very new to UE5

[bleak merlin]

why don't you use a line trace instead

[rugged lion]

i dont know what that is...

[bleak merlin]

you can change the shape of the trace

it makes a line "trace" from one point to another.

and can tell you if you hit an object or not and return data from it

[rugged lion]

ah ok

[bleak merlin]

the way a bunch of fps games determine if you hit your target when you shoot

probably eassier

[rugged lion]

ok give that a try, thank you very much

[bleak merlin]

start should be flash light and end should be calculated amount from flash light + distance to end of light effect

one way of doing it

[rugged lion]

Ill try implementing that thank you

[bleak merlin]

no worries, also check out matthew wadstein's videos

[mild pine]

Hey, Im setting up Chain Lightning, and Im doing a SphereOverlap into a ForEachLoop, and my particle will go from X, to Y, to Z. I would love some tips on how to get the first overlapped actor to be the position of X, the 2nd actor to be Y and third to be Z. Been struggling with this one for a bit 😅

[bleak merlin]

also checkout the unreal engine videos and tutorials on the epic site

[rugged lion]

will do thanks!

[bleak merlin]

are x, y , and z the actors that are overlapped?

[dawn gazelle]

Should be something like looping through the actor array checking which actor is closest and chain to that target, and removing the target from the array as they get hit.

[mild pine]

X Y and Z are the locations Im setting the tangents of the chain lighting, i.e where each "chain" will go to, and as such I need to set the first 3 enemies within an array to these locations

[bleak merlin]

so what if there is only one target or actor? Yuo still have 3 tangents?

[grave apex]

Why is this happening?

when I select the character movement component on one actor, it doesnt show anything in the details

but if I select it in another actor, its details do show up!

[lunar sleet]

Known bug. You’ll need to recreate your character/restore from source control

[elder lodge]

see if you have any bp autosaves

I was able to recover by replacing the file with the autosave renamed

[lunar sleet]

Yeah or source control

[mild pine]

In the cast that there's just 2 targets, I'd have the chain stop on the last one, could just do a check if the array has 3 inputs I guess? 🤔

[bleak merlin]

I would use sphere trace get the overlapped actors. then get the arrange then get the closest and put into pos x, get the next close to that and put pos y, then next close so on. I would make a max jump targets and only take the x closest

then have your lighting hit each of those targets in that order

[zealous moth]

corruption, as neo said, remake it

[jade skiff]

I have a variable named cash. It seems to have two different values in the same blueprint and I don't understand why. Here are the details: It defaults to 25. Every three seconds, it is increased by X (x is number of owned tiles). Every tile the player clicks, cash is decremented by 5 and then the player owns a new tile (this is partially shown in image two). My issue is Cash seems as if it has two different variables. When a player clicks, the UI updates to 20, then jumps to 26 (25 + 1 owned tile), then back to 20, then up to 27, then back to 20 etc. There is a restriction the player must have more then 4 cash to click. This is enforced correctly, but once the player has clicked 5 times cash shifts between 0 and the current number it's increasing to (66, 71, 76, etc) so it looks like the 0 cash is being used and the increasing cash is not being used for anything. Anyone have any thoughts?

[neat basin]

Can we add blueprint node to component owned by actors that have been placed on the level?

[elder lodge]

it's different on both ends of the Set?

[lean compass]

yeah

[ember lichen]

I have a plane and I'm trying to see how hard it hits something in order to decrease a health variable, how can I use the Event Hit in order to see how hard you're crashing?

Also if it does hit 0 health, how would I make it fall to the ground not accepting any input

[lean compass]

fixed it by putting the health changed event in rep notify still kinda dont understand it tho

[elder lodge]

print it before and after
is it the only actor with that code?

[lean compass]

nah theres 2 players

[elder lodge]

that's probably why

see if both players print on one interaction

[iron wing]

I'm having this weird issue where \a widget that has an inputAction node doesn't work when I'm in one level but works in another

[lunar sleet]

You shouldn’t have IA nodes inside widgets

[iron wing]

I'm in ue5

[lunar sleet]

And?

[elder lodge]

Is there a way to rearrange the root transform component ?

I control the camera direction with the mouse but want to keep the camera view locked and rotate the body until the relative camera rotation is 0 again

[lunar sleet]

Input logic doesn’t belong there^

[elder lodge]

rn I'm grabbing world rotation and unrotating the body but jw

[lunar sleet]

Your input should generally be in the character or the player controller, you don’t want to put it inside a widget, because the latter is meant to be transient. If it’s not created yet, the code in it won’t run

[iron wing]

ah ok

thx

[lunar sleet]

Wdym by rearrange, like setting a diff component to be the root?

[vocal stratus]

Anyone know if you can collapse certain parts of custom macro nodes? Would be nice to hide unused pins like other UE nodes that have Advanced options. Like below, I want to hide the N, Any, and Value pins

[vocal stratus]

An example would be Break Hit Result

[elder lodge]

Yeah I'd wanted to rearrange the hierarchy but I gave up on it, a different solution works cleanly

[distant hollow]

My PlayerStart is at Z pos 2000
So my PlayerController spawns there at runtime
But my PlayerCharacter spawns at Z pos 700
No matter what values I change my PlayerStart (100, 5000, 10000) it still spawns at 700
What could be causing this?

[vocal stratus]

You can get the force of the impact by getting the length of the Normal Impulse pin like so

[ember lichen]

Perfect, thanks!

[vocal stratus]

np, hope that helps!

[tough badge]

What's the difference between Async Save/Load and the regular Save/Load blueprint nodes? I tried reading the documentation but I'm pretty smooth brainy and couldn't understand the difference

[lunar sleet]

Async allows a process to happen in the bkg, (on a different thread iirc), so that you don’t get hitches (temporary game freezes or stutters). Generally used when you’re saving/loading a lot of stuff. There’s also async load asset for similar purposes, but in that case for loading assets

[tough badge]

Oh alright. The reason I asked is because I can get my game to save with the normal Save/Load node but it doesn't save when using async so I was curious

[lunar sleet]

Is the Success pin returning false?

[tough badge]

The true pin returns that it completed successfully

Just nothing happens if I load, unless I change the nodes from async to normal then it works fine

[lunar sleet]

Well some older posts on the forums are saying it doesn’t rly work well if anything else is writing

Idk how accurate that is but either way just use sync

[tough badge]

Ah man, would be hhype if it worked

[lunar sleet]

What you’re saving should usually only be vars and not rly heavy

[tough badge]

Yea I'm only testing at the moment so I've just got dummy variables I'm trying to save

I'll test it in a template level and see if the same thing happens

[crisp gulch]

What's a quick and easy way for me to count up this alpha value over a duration of time?

I want to slightly rotate the ship when moving from side to side and someone the other day mentioned I could use FInterp, but I can't seem to find a way to smoothly tick up the alpha value.

[lunar sleet]

Use a timeline and a normal lerp

Make a track 0 to 1 over whatever time you want. Plug the track output into the alpha

[lunar sleet]

Or if you need the exponent and all FInterp will prly work too with the timeline I mentioned

[ember lichen]

How can I get my distance traveled on an infinite runner?

[lunar sleet]

Get the actor location in the beginning, store it in a vector variable. Get the actor location at the end, subtract

[ember lichen]

I want to add 1 to a variable each time I travel X units

[lunar sleet]

Then do that

[ember lichen]

How would I trigger it every 10 units for example without just setting 10,20,etc

[lunar sleet]

It will overcomplicate things I feel, but 🤷‍♂️

[ember lichen]

You think preset numbers would be better?

The problem would be trying to figure out exactly how many units converts to what time

[lunar sleet]

I didn’t say that

I mean there’s like 4 diff built-in functions to keep track of time

Time is not a problem

[ember lichen]

The issue is I need it to be distance based because you can slow down, so it would be easy to beat the system with a timer

[lunar sleet]

Does your character actually move from like X = 0 to X = 250 (for example)?

[ember lichen]

Yes

[lunar sleet]

Ok

So take that difference and multiply/divide as needed

[ember lichen]

Alright

[lunar sleet]

So for example if you want to count 1 meter for every 10 units travelled, (endX - startX) / 10

[lean folio]

Is anybody else having issues with Motion Warping not importing correctly when moving from 5.2 to 5.3?

I validated that Motion Warping is enabled in plugins.

And then I have to reimport motion warping and all of these warp target blueprints.

But then when I save and close and reopen it breaks again. Why do these nodes keep breaking even after readding them again and then saving and reopening the project?

I have tried to replace the existing project and tried to create a copy as well. Both methods return the same results.

[frosty heron]

By moving you mean you open the project in 5.3 ? Or copy the assets from 5.2 to 5.3?

Those red marks normally appear when you haven't compile cpp file

[remote meteor]

might be due to loading phase of the plugin

double check whether if it changed in the .uplugin from 5.2 to 5.3

[lean folio]

I tried both the "make a copy" and "merge with current project" options.

The thing is I remake those motion warping blueprints for that character blueprint to fix the issue and then it comes and saves successfully.

Once I save, close, then reopen the project it's broken again.

[lean folio]

It still appears in the plugins menu for 5.3

[frosty heron]

Check what lAkasa said.
Open the uplugin with text editor then change the version to 5.3

[remote meteor]

trying changing the LoadingPhase to PreDefault

[lean folio]

I am not able to locate the uplugin folder under the project.

[remote meteor]

its on MotionWraping.uplugin

it will be on the engine plugin folder

\Engine\Plugins\Animation\MotionWarping\MotionWarping.uplugin

[frosty heron]

@remote meteor instead of writing the version manually, isn't there a macro for latest version? I prayed I don't have to change version but would be good to know

[remote meteor]

uplugin engine version you mean?

[lean folio]

so this is under the engine folder for UE 5.3 not under my game project folder right?

[remote meteor]

yeh

[remote meteor]

im not sure if this can fix it, but we can try

since reinstalling the engine will remove this change

[lean folio]

Ok restarting now

[remote meteor]

the cause of this is something is loading your bp earlier than the Default loading phase

since this plugin is only loaded on the Default phase, when the bp is loaded eariler, the plugin reference is not available yet

same issues with the Enhanced input node missing back in a few versions 🤷‍♂️

[lean folio]

oh wow no errors

[lean folio]

Looks like that totally fixed it thank you.

Any issues to be on the lookout for incase this fix breaks something?

[frosty heron]

🥳

[remote meteor]

not exactly a good idea to always just push to load earlier. if you could, try on a fresh 5.3 project with motionwraping enabled and used, to see if you can replicate it in a new project.

if it doesn't, might be due to the IncludeOrderVersion in both of the the Target.cs of your project

DefaultBuildSettings = BuildSettingsVersion.V4;
IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_3;

While usually project upgrades is just selecting new version on the uproject. these part needs to manually updated and verified.

[lean folio]

Ok lemme see if I can repro in a fresh 5.3.2 project.

[glossy cloak]

I have an actor component that needs to listen for it's owner's health to change. I don't want to cast because I'd like to use the component on various classes. Is there a good way to use an interface to bind to a dispatcher? Or am I barking up the wrong tree?

[lean folio]

Wait before I repro the issue do I need to change the file back to it's default setting?

[remote meteor]

yeah

[lean folio]

Shoot ok I'll have to test this in the AM.

[remote meteor]

if health is handled by a component, the other component can search the owner for the health component to get stuff
alternatively, you can have a shared based class that handles health
or let the component in question to handle health all together

[glossy cloak]

All good solutions. Thanks!

When using a component to manage all health would you find the component and call functions from it directly (when dealing damage) or would you use an interface and have the interface direct the damage to the component on a base class?

I guess the first one. The second one seems like it's making the entire component pointless.

[remote meteor]

it does make sense to have a interface. for example, you could have multiple actors that shares the same health pool

[remote meteor]

so you query which healthcomponent you should inflict to though an interface

[glossy cloak]

Okay, cool.

[lean folio]

Ok I confirmed this issue happens after saving and restarting a fresh project.

Made a default third person project. Added a Motion Warping Component to the component editor followed by warping nodes in the BP.

Compiled and saved successfully and was able to play the map without any errors.

Saved and Closed.

Reloaded and then everything was broken. So this issue happens regardless of importing the blueprints.

Looks like this issue is a confirmed defect of UE 5.3.2.

QA skills disengage

[serene condor]

how do I jump using the FloatingPawnMovement in a Pawn Blueprint?

[lean folio]

I sent a detailed bug report to Epic Games with full steps to reproduce and everything so that they can look into this Motion Warping issue. Hopefully this just remedied some headaches for Epic and some devs out there using this plugin.

I have a QA background so hopefully this can be helpful over there for them.

[frosty heron]

@fallow needle show your code

[dreamy storm]

Hi all sorry to butt in, I just got some corrupt Blueprints and even 6 months old autosaves won't be accepted by the Engine as a replacement. For God's sake why?

[tall veldt]

Hi! I'm trying to build a city builder.

I have a isometric grid with e.g. 64x64 tiles. I have a function that takes the current mouse position, takes a line trace a based on that Vec3 checks the grid-tile-array for the closest grid position. So it checks 4096 actors simultaneously. This works okay.
But now I want to build zoning, so I save a Grid-tile based on my mouse down, and I save a Grid-tile on mouse up. I extract the x and y positions, and through a loop for x and a loop for y I make a new array of the to-be-zoned tiles. This works okay for small amounts, but whenever I want to zone big portions, it detects an infinite loop. This is because I use the closest grid position function. So e.g. a zone of 30x30 = 900 time the 4096 actors, so 3.6 milllion (which is too much and UE calls this a infinite loop).

How to approach these 2 functions better?

[dreamy storm]

There is a a function to check for actors or components below your mouse, that seems like a better option?

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Game/Player/GetHitResultUnderCursorforObject-/

[frosty heron]

When you want to remove something in iteration, try to use reverse each loop

Yeah

[dawn gazelle]

Removing something from the array doesn't really do anything in this context.

[frosty heron]

Maybe what you want to do is destroy actor?

Then u want to cache it

What u have does nothing as datura says

I get what u want to do tho, in this case do this

Get all actor of class. Promote the result as variable

Then from that variable u can do reverse each loop and remove

Not sure what that person mean

You get a copy of ref anyway

[tall veldt]

That kinda makes more sense yes haha. Thanks!

[glossy cloak]

Anyone know an easy way to keep my screen space widget components aligned to the world location of the actor they're attached to?

[dreamy storm]

This makes ZERO sense to me. How Can something be SO corrupted that it doesn't accept legit old backups??? T_T

https://tenor.com/view/panda-office-rampage-mad-angry-gif-12918172

[dark drum]

It's probably a case you haven't found the source of the corruption. If anything references a corrupt BP, trying to open it will also cause a crash. I had a similiar issue where half of my BP's would cause a crash. I eventually found the source BP which was something used for some UI stuff. After replacing that with a backup, it fixed all the other BP's.

[dreamy storm]

Well after a clean close of the editor it now fucked everything I tried it saved latest, which means a blueprint a widget and a map

For the map it says "failed to load it appears to be an asset file"

which, I might add, is the worst error message to give if you want your user to understand what's going on

[frosty heron]

Use source control

[dreamy storm]

that's great advice... for the future

But I'm quite sure that wouldn't fix my issue in this case, cause like I said older versions are "also" suddenly corrupt

[remote meteor]

It's probably a case you haven't found the source of the corruption.
this

[dreamy storm]

Well I tried deleting anything dependant on it but that does not fix anything sadly

So it might be in the appdata folder or smth, but can't delete anything there cause this is a shite work computer 😠

[dark drum]

With it being a grid, I would store the tiles in a map using the key as an Int Point.

When you do your line trace, you just normalize this to the grid. (Divide by your grid size and round) You can then use this to get it from the map easily without having to loop through all the tiles.

As for the zoning, I would take the first click and normalize to the grid (as before) and on the second click do the same again. With the start and end tile locations, you can then get the zone size and use this to form a 2d loop and add it to the start location and get the tiles from the map.

Hopefully that makes sense but it should significantly reduce your loops.

[lime basin]

yea im too stupid for blueprints please help

[versed sun]

do a Is Valid check

[lime basin]

Ok

[dark drum]

You can just attach the bow to the hand socket so you don't need to keep updating it's location. Generally, it's best to dothis on the item when it's picked up/equiped.

[lime basin]

its already attached im trying to get opposite hand to pull string socket

im doing is valid wrong i bet 🤣

[dark drum]

If your bow is a skeletal mesh, I would do it in it's animBP. Have it check to see if the character that has it equipped is aiming. If it is, update the string based on it's hand socket.

[limber parcel]

you dont need to validate the object when ure already using a validated get...

[lime basin]

bow and player have to different skeletal meshes so that why I think now im not sure I cant do it in players animation blueprint

[dark drum]

The bow can have it's own animBP specific for its own anims. Doing it in the character means the moment you want an NPC or a different character to use a bow, you'll be repeating all your logic.

[lime basin]

yea it does and bow has got its own skeletal mesh

so you are saying to this in bows animBP?

[dark drum]

I would yea.

[lime basin]

I have no idea how to refrence player right hand socket in diffrent animation blueprint :/

player is pawn and bow is actor

[dark drum]

In the bow blueprint, you would want to have a var (most likely of type character) that stores who is currently holding the bow. This way, the bows animBP can cast to it's owner (the bow BP) and get the character that's holding it. From that you can just get the skeletal mesh and the socket from that.

[lime basin]

i will try that is it okay if i dm you about it later if you arent online @dark drum ?

[dark drum]

You can but if i'm busy I probably won't reply. You might get a fast response asking in here (maybe the animation channel depending on the issue)

[lime basin]

okay

thank you

[crystal flax]

Hey guys i am facing a strange issue like i am firing from my gun and when i fire line trace runs and ai dies if line trace hit but the problem is ai is dieng but i am not getting any bone name becasue lien trace is not hitting the ai and ai is dieng bcz of line trace only not by projectile overlaping and you can see in the pic line trace is not hitting the ai can anybody help me i want to get the bone name for headshot

[opaque acorn]

could anyone please explain me how does transforming 0 0 1 vec from viewspace to worldspace giving us the direction of camera ? ? ik its related with material but still there is more on code than a pure material thing

[dark drum]

It's most likely because the line trace is hitting the capsule component and not the skeletal mesh.

[crystal flax]

Okay

[tall veldt]

Yes! I think this is the way. I have it working now, slightly in the direction you are going with this, just need to clean it up now. Thanks !

[dark drum]

No problem. 🙂

[ripe sun]

This is a function. does anybody know why only arrays are locked as "pass as reference"?(This caused a bug for me, now I'm curious)

[versed sun]

It causes a bug , or a warning ?

[dark drum]

This allows you to edit the array inside the function. If you don't want to do this, store it in a local var inside the function and use that instead.

[ripe sun]

I modified the array without knowing it will change the ref, and that caused a bug

[ripe sun]

But I'm curious why it's locked(I know how to work around it)

[dark drum]

Because if it wasn't pass by ref, a lot of the array modifier nodes wouldn't actually have any effect. The input value would always be the same regardless of what you do to it.

[ripe sun]

I know what a ref does, and where it should be used, but why is it locked?

I can't set it to false

You can see it's greyed out

[dark drum]

Because you can't change an input value on a function that isn't pass by ref. Having an input array that isn't pass by ref would me you would only be able to get values from it and if that's all you want to do having it pass by ref wouldn't make a difference.

[ripe sun]

then why aren't maps or sets locked as true?

[dark drum]

Probably an oversight. I can't see any reason why not having it as set by ref would be beneficial as either way you would need to create a local var if you want to make changes that don't affect the input.

[dreamy storm]

Well after 4 hours of trying to get my corrupt files uncorrupted I decided to just roll back a good 20 hours of work

[sweet silo]

damn what corrupted fiels?

[dreamy storm]

^

It corrupted pretty much all autosaves from that day so, have to roll back on older backups

[amber spindle]

Maybe someone could help with branch and hit actor on line trace by channel? I got blueprint BP_Floor and I need to stop further action if line trace hits that bp, but I get problems because target hit isn't bp_floor but is bp_floor2

[open crypt]

I'm testing some ballistics but the output of the hit result for "Distance" is giving me numbers that don't make sense to me - I'm shooting across to what looks to be 30 meters (rough estimate) but it is returning 3.0 am I interpreting this incorrectly? -

In fact no matter where I am it is reporting around a distance of 3 even if I am hitting (and impacting) items all over the place)

[versed sun]

Draw Debug Sphere at your Location to see where you are hitting, you might be hitting a different collision

[dark drum]

It might be best to get the class type and check it matches what your looking for. This way your not checking for a specific object but an object of a specific type.

[sand yacht]

hi, how can I change the default audio input device? Im using an audio capture but I cant specify which mic to use

[open crypt]

I thought this might be the case so I print out the name of the hit actor/component and they are items that are much further away than 3 cm

[night dust]

I'm stuck creating a working delete function in an inventory system which is going to create a display of rows of entered items. So far I can't get the Interface event to fire. This is in-between two widget blueprints, one is a child of the other. I have a child widget checkbox which is inside of a vertical scroll box which is inside of the Main widget blueprint. The display of data entries is working fine. The goal is to have the row containing the checkbox be removed when checked. I have added the checkbox in the last column and included the blueprint nodes for both the Delete checkbox widget(child) graph, and the Main widget event which is intended to both remove the entry from the array and then clear and redraw the display. The Main widget spawns the scroll box with child widgets as they are created at runtime by user inputs. I've used blueprint interfaces before in the door demos so I know they can work, but so far in this project I can't seem to ever get the event to fire off. I've added the interfaces to both widgets, and only one at time while expierementing. It is currently in the Main widget with the event. While testing I know that the message node is being activated, and I can see the values changing via the game instance intermediary variables. The closest I could come was when I created a custom function and casted to it. I could only consistently cause the Editor to crash. What am I missing here? If this whole approach is wrong I'm open to ideas on how to achieve the same effect.

[open crypt]

If the interface isn't firing it means the whatever you are using the reference for in the interface call is coming back null, or you are not implementing the call correctly wherever it should occur

[night dust]

I've been banging my head on this for a couple of days. Perhaps its something obvious I'm missing? What to check?

[open crypt]

The other thing to consider is why you need to use an interface when you should already have a reference to each widget and to eachother

just create events on the widgets themselves and communicate back and forth - then you can use the game instance to call those events if needed, for the time being that should work

[night dust]

How do I access that check box from the game instance?

[open crypt]

whenever you create teh widget you can add a reference to the main widget onto your game instance -

the other thing to remember is that when you "remove from parent" you are effectively deleting the widget from memory, so anything that changed in the widget while it was on screen will be lose, as well as the original reference to it you might have saved

[night dust]

I guess I'm lost on how to change this up? I'm not worried about losing the widget or the data, that's the goal to drop it

[open crypt]

so, first make the event that drops it occur on the actual widget that contains the data itself, literally the child blueprint wherever that price thing is that you are trying to remove

a test might be that on construct you make an event that adds a line, then have a 5 second delay, then run a custom event that deletes that same line, so this ON the actual child widget, the same one

test it to make sure it works

then the next step is to figure out the best way to CALL that custom event from somewhere else

interfaces should be use when the blueprint in question might differ in WHAT it does, - the classic example is you could have an interface call damage on different actors, an "ice actor" might responsd with an event that spawns ice particles, a "stone actor" might spawn stone fragements, but they both will respond to the SAME interface call, "Damage Actor"

[night dust]

Ok, so when I created the custom event, before I was able to crash the editor (lol) but I couldn't understand why it was crashing but I think it had something to do with the REMOVE node

[open crypt]

yes, blueprint structures are great but they can easily causes crashes if you don't handle them correctly

remember, the structure is just a data structure, it is NOT what you see on the widget - that is it's own widget data - you have to change BOTH

[night dust]

So I think thats along the lines of what I was attempting here. first removing the entry, clearing all the child widgets from the scroll box, and then repainting the whole box from the resulting data.

[zealous moth]

to specify: BP structs are great with default data but will be prone to corruption if you add in custom class references

[night dust]

But w/o that event firing nothing has happened yet

[zealous moth]

if you do a struct of int, string, texture, it's fine; if you make a struct of your BP_Enemy and custom classes or other structs, big problem

[open crypt]

Yes, it's better to use a data table of all your custom stuff then load the actors from the data table, by using soft references that you resolve when you need to load the actual actors

[night dust]

If you search on my handle above, I recently dealth with the data structures, successfully actually.

In this case, its all user input at runtime, think of of a table order and receipt. Thats the printout essentially here

[open crypt]

try what i told you to test first

[night dust]

So the Name, item price data is all entered at runtime. I can clear everything by wiping the varaibles in mass

[night dust]

How do I go about that though? Custom event only in the child widget? That does react to the checkbox press, but I still had a the crashes when I tried to remove the entry

[open crypt]

oh, I see - if you are working with teh structure I've had more success, less crashed by using the "make structure node" then you have to "break" the structure first, so all the variables are seperate - you connect the ones you are NOT changing from the old one to the "make structure", then you substitute the changes - it's a bit cumbersome but that's the way I've always had to deal with changing blueprint structures during runtime

[open crypt]

like this

in this case, the "Hit Item" is a stand in for the part of your structure you are removing or changing

the remove should work, and i know you are using an array of your structure but it is probably due to when you are doing it

[night dust]

hmmm. So this would all exist in that child widget alongside the checkbox event?

I just need to get the structure refences to it...? Thinking... thanks for the looksee. this is helpful to change the approach

[open crypt]

YOu can keep the structure variable anywhere you find convenient - I am only recommending that, while you are learning how these different systems work, that you keep it modular - first get it working entirely on one child BP - that way you know the errors aren't because of a null reference or bad blueprint communication

[tall veldt]

Hell yeah, this is great. Much better performance! Thanks

[snow eagle]

Ahoi ! Can i Ask question here for problem in blueprint, i'm stuck with one problem ?

[open crypt]

you don't need to ask to ask, just share your question

[snow eagle]

Thanks ^^
Sry for m'y english in advance i'm not an english native speaker

I want to reproduce a pod racing like game, i wanted for the player to control a pod racer with 2 reactor separatly, the right one with right shoulder right trigger and right thumbstick button and the left one with left button too, with only one Xbox controller, i'm stuck with thé fact that my two reactor are pawns but only one receive input, i have make m'y blueprint code with each good input in his right pawn but the second pawns don't react of his input

I have two player controller and each one possess Is own pawn

[open crypt]

I would look for one of the multiplayer projects in unreal and look at how they handle input - check the learning tab in the Epic Launcher

[snow eagle]

It's for a solo game, the player control separatly the two reactor but with only one Xbox controller

Btw thx for responce me 😄

[open crypt]

you don't need two pawns then

[trim matrix]

There should be one player controller per player in your game. I do not understand why you have multiple.

[open crypt]

you can create an actor with two different "reactors" like a "left reactor" and a right reactor" they might just be static meshes or some other blueprint component

[snow eagle]

Okay i'll try this thx

[dreamy storm]

No problem:)

[wild moth]

Why does it seem that nested structs always break in UE5? Every time I add a member to the nested struct, the main one breaks compile

until I either change a var type, or edit something in it

always "Couldn't parse xyz"

[halcyon vapor]

is there any way to convert a struct to just text, since I know it's possible to import/export data table using xml files, is there a way to get that sort of text from one struct at runtime for debugging purposes?

since I have multiple struct variable that get calculated and passed around, it'd be nice to make a function to more accurately debug rather than making a print string per struct variable of the struct

nvm, found this from json blueprint utilities plugin by epic games

[dry sleet]

Blueprint structs are notoriously fragile.

C++ ones are a little better, but you can still have weird issues if you edit them a lot.

But yeah, blueprint structs are finicky.

[frosty heron]

It doesn't take a nested struct to break what's fundamentally broken. Just declare your struct in cpp. Kinda mandatory

[prime stump]

Hi, if i wanted to check a value against multiple different ranges, is there a better way to do it besides branches for each range?

[elder lodge]

probably not; why?
You might not need multiple branches, you could chain them in an OR statement?

[prime stump]

I need different outcomes based on the range the value falls in so i cant put them together, im just weary of putting loads of things into one single if statement is all so was just wondering if there's a better or cleaner way lol

[cobalt gulch]

So I currently have it where my character can double jump, how can I make it so if the down button is pressed you fall faster. Like in Smash Bros

If you need different logic based on different outcomes, not sure how else you can manage
There are switch statements; not sure if those can be reconfigured for ranges.

Probably not, I wouldn't know how to do that even in code

unless you can collapse those ranges into states

[elder lodge]

try Gravity Scale under CMC

[lunar sleet]

Use the #enhanced-input-system and the triggered pin when using Down or no trigger. And get sued by Disney while you’re at it 😀

[cobalt gulch]

they can't aha

[elder lodge]

it's not a lightsaber it's a photon-blade™

[cobalt gulch]

They cant trademark unreal light beams

[prime stump]

i don't think that's how that works 😆

[trim matrix]

So i've tried to see why calling functions on widget is crashing editor and most likley game and below is what I'm getting. For me I would see that as well somehow the function is being run not on game thread like it says

Assertion failed: IsInGameThread() || IsInSlateThread() [File:F:/DEV/ND23-BuildPublicEditor-EpicRelease/Engine/Source/Runtime/SlateCore/Private/Widgets/SWidget.cpp] [Line: 1119] Slate can only be accessed from the GameThread or the SlateLoadingThread!

I can't access the Cpp side so can only do BP stuff

Thats from the log

seems to try setting the text but then doesn't appear to have managed to call the other function

[marble tusk]

I'm curious, are you splitting struct pins at all while doing that or are you only using break struct nodes?

[trim matrix]

There the two functions I'm calling and yeah

[wild moth]

Splitting?

I break the structs and also use them as params, idk regular stuff

[marble tusk]

Like right click -> split on the struct pin in order to access the params in it

I take that as a no

[wild moth]

No i hate doing that

Too much clutter

[marble tusk]

Okay, well that's my theory out the window. I've personally only had issues like that when splitting instead of using break nodes

Maybe splitting just makes it more likely to happen or something

[frosty heron]

use cpp struct 🙏

you don't even need to know cpp, make a blueprint struct. Right click and view header file

pretty much just copy paste from there

hey How would i make it trace in a random angle Down

like this

imagain the red circle being the Impact point

and the "yellow lines" are the Random angle always going downwards

is ok i solved it 😛

[tough badge]

If I use the save game to slot node where can I physically find the save file? Where does that node save things to

as soon as I ask a question I find it nevermind im big dumb EDIT: For me it was under UnrealProjects > (Project Name) > Saved > SavedGames

[frosty heron]

You can also print string get saved directory node

[prime stump]

Hi, i need some help.. i need to make it so when the players health is updated it checks if that health value falls between 1 of 3 ranges, if it does it calls an event to do some stuff based on the range its in but I'm not sure how best to set it up

At the moment I have this 'CheckHealthForHeartbeatSound' event that gets called any time damage is applied, but because its getting called every time damage happens the 'SetHeartbeatHealthRange' event is called multiple times because, for example, any value between 50 and 25 health is within the 'half health' range so when the players health hits 50 'SetHeartbeatHealthRange' is called, again when they hit 40 health and again at 30 health, so ideally i'd like for it to only be called once when the player's health has first entered into that range rather that every time there health meets the requirements to be in that range.. if that makes sense

I tried it with Do Once nodes but i realise that it wont work properly and it causes another issue because hitting one range should actually reset the Do Once's of all other ranges so im not really sure how to best do it, any ideas?

[edgy ingot]

Simple nested if will call once

It goes to true then thats it

Reason why stuf is called multiple times is most likely because you are doing multiplayer

#multiplayer

Btw i just read your problem again

Just set the state (enum) there then do a check

For example on low health if state is already low health do nothing

Otherwise set state to low health

[prime stump]

It calls multiple times because the range itself can be hit multiple times, the first range of between min 25 and max 50, 50 health, 40 health and 30 health all make that range go true

Gonna try the enum thing now tho

[edgy ingot]

If u r trying to change an enum state, then simply have a check if the state is already the same will suffice

[waxen fog]

Can widgets be spawned on an actor if it is not a character?

I have a widget childed to an actor but it does not appear when playing. it does apper in scene view however

it is in world space

this wont work because the actor is not a character so does not have a player controller. I assume you cant attach to a viewport without a conroller reference.

I have a local co-op game. Getting 1st player controller and using it for owner player also does not work for this

[edgy ingot]

You can attach widget comp to any scene comp

Dont matter wat it is, including character, pawn or an actor

[untold niche]

Question: How do you make a variable instance editable, but only visible if you check a boolean true?
So like having hidden variables in the editor that you can't see unless you check that you want to use them

[steady night]

it kinda works but the range is like unlimmited :/?

[edgy ingot]

@untold niche probably not possible with bp. But i see gas pop more option when certain condition is met eg. Ticking a box. so im sure its a thing in cpp. But in bp ? Dunnoe

[loud tree]

Anyone have a reliable method of binding spawn points together?

Ie
If player spawns at this spawn then Spawn another actor at the spawn it's linked to.

Hopefully that makes sense 😅

[dire frost]

Might wanna normilze the rotate result then multiply by the length you want

[dire frost]

Just have one spawn point reference the other?

[loud tree]

Yeah. My player spawns are picked at random, and I need a second spawn tied specific to each spawn point.

[steady night]

@dire frost hm that broke it

https://gyazo.com/51264f9d4345b7e9f8b89a99b708bb95

https://gyazo.com/99e84f0fd3ea80ca766e34cc378ffd8c

[dire frost]

Still wouldn't change my proposed method. You can either have two sets of spawns, one for player the other for actor. Or just have very spawn point reference the other one randomly (or not)

[dire frost]

Wym?

[steady night]

look at the links

[loud tree]

I misread your original reply... lol sorry. I thought you were asking if I wanted to have one reference the other 😂

Would this be done in the level blueprint?

[dire frost]

Preferably not. Gamemode would be best suited for this kind of logic

[dire frost]

The vid is not playing for me 😅

[steady night]

oh

ok well its only going in 1 straight direction

[edgy ingot]

Struct or map

[dire frost]

I mean yeah you only rotate it a certain angle

Might wanna add some random float in range to it

[steady night]

erhm

[loud tree]

It's not a struct, and if you mean like a mapping function no to that as well.

If you're referring to the random spawning
I pull all actors of class and assign that location to a player controller on a for each loop that removes that index after.

[vivid bridge]

This is in a Character blueprint. Is binding to the On Landed event limited to the ability task in the error message?

[edgy ingot]

Im saying you can use struct or map to pair objects.

Eg player start, spawn point

[dire frost]

Just a question why are you binding instead of overriding the event?

[loud tree]

Didn't know you could do that. I'll have to look into it when I g3t back

[dire frost]

A map is a data type btw. It's like a pair of key and value where you use the key to quickly find the value

[vivid bridge]

I want to unbind it at a certain point. Basically when a character is in a specific state I want to play a sound effect whenever they land, but not when they aren't in that state

[dire frost]

I'd honestly just have a bool check

Instead of the hoola hoops to bind and unbind an event that could either lead to bugs or a painful dev experience

[vivid bridge]

sure that's easier for now, but this is what binding events is for, right?

for me personally having the logic for this event nearby the logic for entering the state is much cleaner and easier to understand than a bool in an event somewhere completely different

[dire frost]

For this specific case (on landed event) it's more of a workaround to make virtual functions in cpp work in bp

[faint pasture]

a widget isn't a thing that's spawned, a widget COMPONENT can be

[dire frost]

I mean you could just set the book to false where you'd unbind the event, no?

So basically same code just...easier to deal with ig

[vivid bridge]

yeah but there's still the asterisk of having to go find where the bool is checked and what it actually does. and it could be among a sequence of totally unrelated boolean checks if I do this multiple times

[loud tree]

Thank you for the Info
And thank you as well summer.

I really appreciate it as always.

[dire frost]

That's just something that could be avoided by engineering your code better

The name alone should be enough to tell you what the bool does

You never ask yourself "hmmm what does this 'IsLanded' mean" cause the name describes its purpose

[worn kestrel]

Hey there! I got some help yesterday making a system that updates the players score everytime they enter a trigger. I also followed a tutorial making a leaderboard for multiplayer. Right now my BP for point giving is not multiplayer and I tried myself but it still only shows in one game and also gives to both accounts. Is there a easy way to fix this or is it complicated haha😅 Still kinda new to this so thanks for any and all help!

[vivid bridge]

I think this is getting into more of a philosophical discussion about code structuring here but I personally don't think that throwing the bool check and logic somewhere else is necessarily better, even with a well-named bool

seems like we just have different preferences for how to organize, which is fine but ideally I'd also like to know if my way is possible/how to do it

I think I found it, had to bind to the Landed Delegate instead of the On Landed event (which I think belongs to something else besides the Character)

[dawn gazelle]

RPC to a client indicates that you're trying to replicate something to the owning client. It doesn't get called if there is no client owner and you're likely getting warnings in your log about this indicating sometihng along the lines of no owning connection.
Score values are something that should likely be a replicated variable set by the server anyway. If you use an OnRep, you can then use that to drive the UI updates.

[faint pasture]

no RPC needed here

Just change the score serverside and use repnotify to see it change clientside

[worn kestrel]

Okay, got a better idea of what to do! God I love this DC😅 Thank you guys for the awesome help! ❤️

[dire frost]

Glad you got your issue sorted out! My advice before came from a painful experience I had when I did what you did exactly (binding/unbinding delegates to avoid using bools) tho the reason why is different (I thought my approach was "optimised" spoiler: it wasn't lol) i still had to deal with spaghetti code where the event worked then stopped working seemingly randomly and it was so annoying that I needed to recreate my character class from scratch just to fix it up!

Obviously you didn't need to follow my advice after all I'm just some hobbyist on the internet but I hope you at least take it into consideration

[vivid bridge]

No totally I appreciate you offering it! Always appreciate help and input, helps me work through the issue no matter what

I also don't think my way is going to be any more optimized, but just to know going forward, did you ever figure out why your issue was happening?

[dire frost]

Just some flawed logic in the code 😅

The ones going out from the green nodes specifically

Those can be a big performance trap

Since they're executed every time you "get" the value. Unlike the blue node

[vivid bridge]

haha classic. And ironically, I'm probably doing something more like the boolean approach now because I found another time I want to execute my code now and there isn't a built-in delegate for it 😅

[hexed scroll]

Hey, I could use a little bit of help if anyone has an idea of what I'm doing wrong here. I'm trying to create an automatic fire setting for a weapon. I currently have it set up in a While Loop, but it seems to generate all the bullets in the magazine at once, rather than running through the full While loop and waiting for the delay to complete to generate the next bullet. Any idea why this might be happening?

https://cdn.discordapp.com/attachments/828392589300465694/1179908598470557818/image.png?ex=657b7e83&is=65690983&hm=e235b52ed89041115a2bdff9703114b70e91e999912e6505a15fb042583a3a5e&

[elder lodge]

while loops don't work that way i believe

[dire frost]

Welcome to unreal my friend :)

[elder lodge]

loop logic shouldn't encompass more than the tick

you think adding the delay fixes that but it doesn't, i don't think

If you want something to span ticks gotta do it differently

[dire frost]

You don't want to use a while loop here. Loops in general will suspend execution until the loop is exited

[hexed scroll]

Oh, I see. So if I want to loop then I need to place it on the event tick?

[dire frost]

You'll want to use a timer instead

[hexed scroll]

Oh, ok! I'll start researching timers, then!

[dire frost]

Oh god please no lmao

[ionic palm]

Do any of you know if it is possible to edit data table values for an item in blueprints?

I am trying to come up with a solution for varying resources cost and sell price per merchant child based on the proximity of the resource to the merchant. This I can edit manually based on the merchants location I don't need to do any distant casting or anything I am not a maniac haha

I have found a few potential ways to do it but all have their flaws. Most recently I found a way to check the owner of the inventory widget and if it is equal to the base merchant nothing happens and if it it isn't and is equal to merchant two I adjust the price and then this gets forwarded to the merchant inventory component and edits the buy and sell price there. This however doesn't work for individual items so I can only change the price inflation for everything in their inventory.

I was thinking a much simpler and cleaner solution, after 3-4 hours of tinkering to get the last solution to work, why don't I just trigger an event, based on a box unique to each merchant, which manually overrides the buy and sell price of individual items and then resets them back to normal when exiting the shop. I can't seem to find a node to make this happen though.

If I could edit the variables of the item directly as well i won't have to update any of the other UI code to compensate for the changes making it about 10x more simple to impliment

[faint pasture]

You can do it quick and dirty with a delay. The delay fires its output x seconds after its input is fired

so use the delay to loop back around and check if the trigger is still held down,

Fire -> Open Gate -> Enter Gate -> Fire Gun -> Delay -> Back to Enter Gate
StopFire -> Close Gate

or you can use a bool like
Fire -> bool = true -> if bool -> fire bullet -> delay -> back to branch
StopFire -> bool = false

or the timer approach

Fire -> start timer
StopFire -> end Timer

Timer -> fire bullet

[dire frost]

I think timers would be an easier solution, no? 😄

[faint pasture]

delay is probably best for babbies first automatic weapon but yeah a timer is the play for anything real

[dire frost]

Fair but tbh this had me having a heartache and I'm not even a baby (more like an infant by still)

[hexed scroll]

Ok, I'll look into both and see what works best for my needs, then. I appreciate the input. I was stuck scratching my head on why that didn't work for a while

[faint pasture]

To reiterate, your while loop will loop continually in a single frame, also nothing is connected to the output of your delay so it might as well not even be there

While is not for stuff over time

It's just a 1 frame mag dump

[hexed scroll]

Fair enough. I'm coming from Unity and I was operating off the logic of it working like a coroutine WaitForSeconds which I'm gathering is not right

[dire frost]

Unreal just officially supported coroutines in 5.3 lol

Might be a while till they reach blueprints if ever

[hexed scroll]

Makes a lot of sense that it didn't work how I thought it did, then lmao

[faint pasture]

Delay is like that

but you're not doing anything after waiting

Enter -> wait -> do the thing after waiting

You're doing
While loop -> body -> wait -> ??? -> nothing

you're hittin them with the wait for it without ever giving them the DARY

giving the computer a cliffhanger

[hexed scroll]

I see. My logic was While loop > body > wait > loop

[faint pasture]

still the while loop will zoom

it'll say wait wait wait wait wait

it has no limit on its entry

the wait has to be BEFORE going back into the loop,

which isn't really a thing, you make it yourself like my examples

[coarse grove]

Its also possible to create your own macro with delay, you can create a while with delay or a for loop with delay aswell

This way

[faint pasture]

yup

in BP a while and a for are both macros already so it's fairly simple to extend them to have delay

[heady burrow]

Whats the proper way of capturing a mouse over on a static mesh or actor and get it's relative coordinates ?

I've found like 3 ways so far but.not sure if I'm messing up

[versed sun]

do you want to be alerted of mouse over , or choose when/where to check ?

[heady burrow]

I need to get the coordinates every time the mouse updates it's local position

So I can then move a UI tile

In a snap grid fashion

[versed sun]

like a widget UI ?

[heady burrow]

It's an actor actually

Like a selection tile of sorts

[versed sun]

ok, then you can go Player Controller > Under Cursor? forget the node name but you get it off of player controller

[heady burrow]

right but should I use the getHitUnderChannel one you say

[versed sun]

and you get a hit result for whats under mouse

yah

[heady burrow]

ok, so I shouldnt use the custom events in the playercontroller

they have an array of possible mouse interactions

ideally I would like to make it so only the tile moves when the mouse is over the board, in my case

so picture like a chess board, if the mouse is not over the board nothing happens

[versed sun]

ok

[heady burrow]

when I start hovering in the area of the board the selection tile moves, but only on the tiles

(the only on the tiles shouldnt be a problem)

just need to capture the proper coordinates

[versed sun]

sec , loading my similar project

I did it like this , whenever my mouse moves

Made my own channel for my tiles, if it doesnt hit , then you are off board

[heady burrow]

ah, thats the part of the puzzle Im missing

I was messing around with the objectTypes enum

but didnt understand exactly how it worked

so you created your own trace channel?

any documentation on how to do that

or I can swing it

[versed sun]

yes , in project settings , you make add trace channel

[heady burrow]

nice

btw when you say "whenever my mouse moves"

you have the actionable node tied to a tick?

[versed sun]

not "tick" but when IA_Mouse Look fires

or whatever i called it

[heady burrow]

no idea whats that

[versed sun]

Enhanced Input systen

[heady burrow]

ah ok I will read about that, first time I hear it.

I guess I could also bind a mouse event inside the board actor

not sure if its a good practice

[verbal igloo]

I literally have this bug on my project, it seems that it affects all 5.3.x versions, and the version fixed is 5.4? What should I do? 5.4 is not released yet

Should I go back to 5.2.x version?

Okay, I decided to not use overlap detection

Now I'm just detecting how far away the player is from the object

It's working perfectly, it's a good work around for it

[lunar sleet]

This is about #cpp

[sand yacht]

Hey, how can I fix this error? What should I put into the owner

im constructing an actor component

[verbal igloo]

not really, I'm using bp and it's about general bug, so doesn't matter, and why do you mind? if you don't have the solution just don't answer lol

[velvet sparrow]

Hello! I have a problem with my grenade launcher, I have been trying to make a charge up mechanic that will change the distance the projectile is shot the longer you hold down the fire button. However, when I attempted to use the cast function to get the speed, it had multiple errors and warnings. I also couldn't figure out how to set the initial speed of the projectile using a variable. I am using Unreal version 5.2, Any help will be greatly appreciated, thank you!

[visual stump]

Hello I have a pawn that has a floating pawn movement component, any ideas of how can I get it to get to the other side using an ai controller? because even though it floats it still needs a nav mesh

[kind estuary]

How do i make sure a character or object is destroyed when they fall from the floor into the abysm ?

should i create box collisions around for this?

[lunar sleet]

I don’t mind, just saying the screenshot you took referred to a cpp function so you might have better luck there. No idea how you’re using it in bp since that function doesn’t exist there as far as I can tell but power to you

[lunar sleet]

Yeah there’s a few issues. Not sure where you got that proj movement component node in there, your bp would need to contain a PMC to use that

Also, you can’t cast a PMC to a projectile bp, a cast checks if a ref is of a certain type (class) and lets you access its insides if so

[verbal igloo]

If you use, for example, the event end overlap on bp to know if you character stopped overlapping with an actor, if you stop overlapping while rotating, it won't detect it and the code won't run

I was trying to get a work around on this using bp

[verbal igloo]

It's only when rotating

[lunar sleet]

Weird, I haven’t seen that before, though I have seen collision detection issues with sphere collisions given that you can easily go from overlapping to not overlapping given the surface type, using a box fixes that tho

Perhaps use a box collision to fatten up your actor a bit, if it doesn’t need to be super precise

[verbal igloo]

The error didn't exist on 5.2.x

[verbal igloo]

When I found this, I tested and ralised this is exactly my bug and it's only when rotating as it says lol, really strange

[lunar sleet]

Sure, you can create a trigger volume. Alternatively you could run a check on tick to check if they went past a certain Z value

[verbal igloo]

and they will only fix on 5.4 probably

[lunar sleet]

I believe you, I just found it odd that they were talking about a cpp function only in that screenshot but ig it affects all overlaps

[verbal igloo]

Yeah, and it's sad they didn't fix that already

[kind estuary]

yeah was thinking about checking it on tick. But the trigger volume is better because it doesnt check like crazy for something that will happen only once

[teal yew]

I need some help(UE 4.20.3) for a random integer timer that activates something

[tough badge]

So I have a question about the Casting/the Cast node. If I cast something in a level to something like the Game Instance will that hurt performance? I figure since the Game Instance is always loaded anyway it shouldn't be that big of a performance hit but I'm not sure

[edgy ingot]

If you care about performance you wouldnt use bp to begin with.

Casting is free, its the hard ref from the cast that make the ref loaded to memory in bp.

If you make a cpp base class to it. Eg game mode. Casting to the cpp version will not force load the asset to memory

Anyway for something like game instance and character, they will always be loaded. So cast to them anyway
