blueprint

[wild moat]

right, have that

[lyric quiver]

thanks

[frosty heron]

It's there for me

[remote meteor]

or you can use this

[frosty heron]

but get widget is the same yea

[spark steppe]

because text widget isn't a user widget

[wild moat]

OH!

[frosty heron]

I would check the W_TextWidget type

[wild moat]

i'm in construction script

it shows up elsewhere

[remote meteor]

ah yeah

[spark steppe]

why do you even use get widget?

[remote meteor]

on construction you cant really use user widget object

[spark steppe]

the reference is already "pointing" to the widget

[remote meteor]

its not construction safe

[wild moat]

i just need to change the text based on editor text input

[remote meteor]

GetWidget should be fine

[wild moat]

doing a bit of rendering:

[spark steppe]

oh, i see it's a widget component...

[wild moat]

alternatively, if you know how to get a scene capture component to render text render component, i can avoid the headache of umg:

[spark steppe]

the text renderer requires a weird font format iirc

[remote meteor]

oh forgot to press compile

[spark steppe]

and often looks poop

[spark steppe]

what is the warning here?

[spark steppe]

did you compile?

after adding get widget

[wild moat]

omfg

[frosty berry]

If I want to have enemies that can walk, crawl, hover, etc (Zombies/aliens, spiders, hovering attack bots), what kind of BP base class should I use? I Know I can use Character base for walking enemies. Should I make my own movement bp for crawlers and use FloatingPawnMovement for hover bots... as in have 3 base classes to build enemies off of, and use an Interface to tie in functions and a simple base class to share variables?

[remote meteor]

does the hover needs to be real hover(as in actually have vertical movement? if not, you can just use character's CMC for all of it

[dry sleet]

Depends. Single player game?

[remote meteor]

just offset the "hovering" mesh in to the air

[fiery tiger]

Can anyone tell me how to properly check if an instance of an object within an array is element zero before I tell it to destroy? I have tiles I'm spawning and will eventually destroy if specific conditions are met but I want to ensure I'm getting rid of the oldest existing one.

[frosty berry]

Single player game, (I understand and use inheritance) just trying to map out best path for different movements types.

[frosty berry]

for crawlers and hovers alike.

[ancient heath]

And dont use Add Impulse?

[remote meteor]

if its a projectile, you can use a projectile movement component

spawn the projectile in correct orientation, projectile have InitialSpeed that it will set itself and start moving forward

[wild moat]

so the bp is fine but my widget wont update the text:

[dry sleet]

AddImpulse only has an effect if it is applied to a primitive component that has SimulatePhysics enabled.

Which I guess your projectile doesn't.

[ancient heath]

Of course, I don't have it

If I add it to the transform, the projectile doesn't spawn, I guess it teleports to some strange coordinate

It's harder than I thought to do this.

[remote meteor]

should be fine, though mine is a function instead of an event, they shouldn't matter though.
make sure the widget class is already set in the WidgetComponent

[wild moat]

yeah that's what i ended up doing, one extra click to update the text but i'm fine with that

[ancient heath]

Sorry, I didn't mean add impulse, I mean add force.

[shell wren]

Currently getting a error with not much direction, best way to debug this? It's a BP controller that was reparented to another BP controller(but this controller is cpp based) I've done this before with this controller + another bp prior without issue
Overriden function is not compatible with the parent function <None> . Check flags: Exec, Final, Static.

[lunar sleet]

Flags are things you set on the #cpp side, you’re prly missing some

But also if you had an inherited function and now the new parent doesn’t have that, it might be what it’s trying to tell you

[cerulean stratus]

for the life of me i cannot figure out why this does not make this static mesh component rotate towards the other static mesh component, can anyone help out?

[lunar sleet]

Are they separate actors?

[cerulean stratus]

no each is a component of same bp

[lunar sleet]

Try using relative rotation then

[cerulean stratus]

for the record i couldn't get this to work with separate actors either haha

relative rotation didn't work

[lunar sleet]

Try attaching one to the other

Relative usually means in relation to attach parent

[cerulean stratus]

no dice

[lunar sleet]

Tbh idk if you can do find look at rotation like that

Usually it’s actor rotation to another actor

What usually helps me with this stuff is debugging

[faint pasture]

none of that matters

[lunar sleet]

Set a breakpoint and when it drops hover over the input and output pins to see what actual values are coming through

[faint pasture]

debug your data first and make sure it's all what it should be

[faint pasture]

This should rotate Body to align its local X with Sphere.
You might have something else also settings its rotation later, overriding this (like control rotation).
Body and Shere locations might not be what you think.

[modest monolith]

I have a rope which is a static mesh. Is it possible to add a skeleton to it? Otherwise I can't simulate physics as it is a basically a stick

[lunar sleet]

It needs to be converted to a skeletal mesh.

If you have 5.3 it’s one click, if not you need to export and reimport it (tho that can be finicky at times)

[modest monolith]

I've UE4

[lunar sleet]

Ugh

the export and import as SKM might work, I’m not sure

[modest monolith]

Thank you!!

[ember junco]

if I have the vehicle at 0,0,0 in world partition it the child actor stays attached with physics constraint, if I drag this to a distance of 10,000 on X it will stay attached

If I have the vehicle at 10,000, 0, 0 and jump in the child bp physics constraint fails and it falls through the world

[flat coral]

What's the cleanest way to do like a SEQUENCE on Enum values, rather than SWITCH on enum values? Basically I want to do something for each of these, but this isn't a for-each loop, I'm executing an entirely different code path for each one

(The goal here is making a sorta report UI, where there's a different widget that needs to be updated for how many of each type you have)

[dawn gazelle]

I think there's a foreach enum.

[versed sun]

for each{Enum name}

[cerulean stratus]

this got me the results i wanted. body and sphere are where they should be, rotation of actor and all components default to 0,0,0, there's nothing changing the rotation of the actor before or after the function is called. so confused

[cerulean stratus]

doesn't matter if the node is set actor rotation, set actor relative rotation, or set relative rotation of body as in screenshot above, they all provide same result

i'm thinking finding rotations in scriptable tools is buggy or i'm missing something very obvious

most likely the latter

[quiet pasture]

does anyone know how to set new skeletal mesh on skeletal mesh component, so the associated ABP doesn't stop working?

ABP works fine if a mesh is set upfront, but setting a new one causes the actor to T pose

[vocal prism]

is there any way to make this thing hit multiple times

for my project i need this sphere trace to trace per frame instead of just once is there any possible way?

or just with a regular interval of atleast like .5 seconds

if someone knows a answer or solution pls let me know

[dire frost]

you'll want to use tick or timer

if the interval is not too small (.5 secs is fine) then i recommend using a timer

if you want a more frequent traces then use tick

[vocal prism]

which timer should i use?

i want to use tick but i already use event tick for something else or is there another tick variant?

[dire frost]

set tick by name or event both should work fine

[dire frost]

nope. but i think for just one trace it's fine

one trace per frame i mean

[vocal prism]

this one?

[dire frost]

sure

make sure to save the return value into a variable so you can pause or stop the timer later

[vocal prism]

i think its not possible for that node to tick multiple times

[dire frost]

hmm?

just call the set timer once

[vocal prism]

i checked the unreal doc and it says only once

[dire frost]

huh?? the timer's only purpose in life is to call a function multiple times! (or be used like a timer...)

[vocal prism]

should i record a video so you can see what is going on?

because it is pretty difficult to explain it

[dire frost]

no just a screenshot of your code is fine

[vocal prism]

so i want to make a pickup and then place it at a different location and it also snaps on the grid i made

[dire frost]

ah yeah you need to wrap all the code right next to the timer in a function (let's call it repeater). then for the function name put "repeater"

[vocal prism]

it works half way but because the sphere trace only ticks once the object TPs back to the first close tick

[dire frost]

the timer doesnt cause the nodes next to it to be called multiple times

[vocal prism]

ohh so i have to make it a group and then the end result will be repeated?

[dire frost]

yeah just group the nodes into a function. the timer will then call that function multiple times in a set intervel

[vocal prism]

should it look something like this? or do you want me to split it up entirely

[dire frost]

no i meant to pick the nodes you want to be repeated, right click->group into function. then put the name of that newly created function into the timer

[vocal prism]

I got this now but it still doesnt repeat the node could you point out what im doing wrong?

[gaunt stirrup]

Is there a way I can have each button select a certain default pawn for the level? please help

[dire frost]

oh yeah the timer doesnt pass params through, you'll need to save them and use that saved var instead

[vocal prism]

i dont understand, sorry how do i save them?

i didnt even know you could make functions before you told me this 😅

[dire frost]

just create a variable and set that to the function inputs

[dire frost]

a neat little unreal hack for ya

[vocal prism]

Did you mean this ^

[silk hinge]

hey guys, any chance someone can explain me a little thing ?
My issue is simple, From server (player host) I cant see the client Aimoffset, but from client I can see the server AimOffset, here is how is the code setup, I followed a tutorial, it's not that bad but there is a few things I did not understand.

The code is fired from a "receive controller changed"

The fuction is fired over and over from the timer event
And receive controller changed is firing on server / client normally, so I wonder what is preventing the server from having the client Aimoffset Replicated, also the rotator variable is set to "replicated : SkipOwner"

[dire frost]

no...if you're struggling with basic bp functionality i'd sugget following a tutorial before making your project. you can check the #ue5-general pinned messages for that

[modest monolith]

Do you know why I run with Shift and interact with F but if I interact with something with F while I'm running holdin shift F doesn't work? I can't interact with stuff while running

I have to stop holding shift for that

[river swallow]

Is there a reason to not 'reuse' a variable like 'Size Box Root' above? Its cleaner to pull it out twice and use it as the target for the width and height... but im wondering if there is a functional reason to not just use one 'Size Box Root' and apply it as target for both overrides

[trim matrix]

So i'm watching a tutorial online for making the player character always be looking toward the camera looking. The impact below is from the video I'm waching and on the control rig that they have open some of them nodes I simply do not have

so To Rotator and From Rotator, are they names something different or something

[faint hound]

is there any way to do assertions inside blueprints? like there's an invalid state that should never be reached and I want to stop execution

[frosty heron]

what sort of state? if you are accessing out of bound array u will get error in the outputlog

same thing with accessing null ptr

[faint hound]

bad casts

[faint hound]

for instance, if this cast fails I want to stop everything because something is badly configured

[versed sun]

put a Print with a Break Point

[silk hinge]

If this cast fails nothing will happen anyway, since nothing is plugged to fail, I don't understand the exemple

[versed sun]

i do that when i want to alert myself that i forgot to input a setting

[faint hound]

yeah, I want the game to stop running if that happens

it's in a bad state

well, not necessarily stop running, but at least alert me if that happens

[silk hinge]

When your developping use print string to see the error, otherwhise the game will just quit and getting answers on what happened is even more confusing

Print string and wright into it "this cast failed" and keep it printed on screen for 5sec for exemple

Press F9 to run a breakpoint on a selected node as well to see what nodes are fired and what results they give

[faint hound]

alright, thanks guys!

[heady burrow]

Whats a good way of going into pause mode? meaning that actors that were previously moving or shooting will stop

including mid-air projectiles, for example.

or any DoT too

I can always manually mess with tick event

but is there a better way?

[trim matrix]

Anyone have a good source for how I would implement a Aim can't of thing ?

It seems the videos etc on youtube are either UE4 or I don't have same nodes as them etc

[silk hinge]

you Mean ADS ?

Aim down sight ?

[trim matrix]

yeah and also when your not aiming down sight still want like the character to lean forward and back obvs else it'll look bit wierd

one video i just watched did it using control rig but it was using Nodes I don't have etc

nevermind I believe I've got it to work and it seems it may be just how they set their variables aren't same for me

[ancient heath]

Hey, does anyone know how I can direct a projectile with add force or add impulse to where my camera is looking?

I made some attempts but they didn't work

[silk hinge]

get forward vector from your camera ?

[silk hinge]

well, I can send you something that a guy made with a template, then you can dig into it to understand how the guy made a decent ADS with the camera manager in a verry optimised way,

The tutorial in under UE4 but you can migrate to UE5 easily, and re use some code to your project, this is by far the best FPS feeling tutorial I could find, and it also shows you a bit about replication, but it's not a beginner tutorial at all, with 0 explaination

it takes in consideration

Left hand location on weapon
Aim down sight
Sprint
Crouch
Aimoffset
Weapon Sway
Turn in place rotation
Seperate Upper and Lower body

etc...

but if your new to UE, you most likely will not understand anything about it

[faint sand]

is this expected - i have a child character based on parent character. i edit parent character with new event, but its not showing up in child character. other changes ive made, like camera location, and added components and widgest show up, but not this event (keyboard 1). is this normal?

[silk hinge]

#blueprint message If anyone can help me with that one

[ancient heath]

Currently to get where I'm looking, I'm using a line trace by channel, that's not the problem, I don't know how to direct the projectile in that direction

[hardy tide]

Hey there Elian, have you tried Forward vector?

(get forward vector from the camera, or whatever you wanna shot from, and plug that into the direction for the add force/impulse)

(also multiply the vector X float)

[trim matrix]

I'm not new to UE but depends what they done it on as the opitmised ways of doing stuff are here and there with me

[hardy tide]

then plug

Btw guise, im trying to do something with arrays, and for the life of me i can never understand arrays properly. Heres the problem:

I have 7 actors running through a spline, so i want to position them according to the distance along the spline (i managed to get the distance)

But how would i go around to getting those distances, and getting out a position for the racers? i got stuck at here:

(Ignore the tick, is just for test purposes)

even if i do manage to sort throughout the floats, and sort them in size, how do i know which distance belongs to who?

[silk hinge]

well, most opitimsed way of ADS was for me, camera manager

[dawn gazelle]

You shouldn't need to have the timer set to looping to then have it call itself again to rebind the timer.
Replication only happens from Server > Clients. Your RepAimOffset function then won't execute properly for the client on the server as the client's character isn't locally controlled.

[faint sand]

how do i Possess a character without moving my camera to that character. assume i have a field of 5 on the board. i want my camera to be static but be able to switch characters on the board without moving my camera to them. - Note: i do not have any camera actors on the character bp.

[silk hinge]

why do I feel stupid to dont even understand anything you said on this one ? xD

It's looping every frame cause the offset is replicated manually to the other people, without the refresh of the control rotation it would stop moving for the other clients.

So this means that the Server is not getting the infos from the other clients, about where they are looking at ?

[ancient heath]

i will try this

[flat coral]

What does this warning even mean? How is the default value even relevant during a Set call?

[dawn gazelle]

Control rotation is sent from clients to the server automatically, but replication of variables only happens from server > clients.
That means in here, it will only ever work when the server is calling this function on its controlled character as the server is the authority, and it has it locally controlled.
If the server is calling this code for another pawn that they aren't in control of, then your branch will return false as it's not locally controlled.
If a client ends up calling this same bit of code, they do not have authority, so the branch will return false, and even if it did return true, then it won't replicate to anyone as its set on the client, not the server.

[dawn gazelle]

In terms of the timer, this is some odd logic.
You're binding the timer to call the event that is creating the timer, and also setting the timer to loop.
It doesn't need to be set to loop if you're constantly creating the timer again.
And it's a bit nonsensical to even use this.... You may as well use tick to call RepAimOffset (after a HasAuthority check) as you're basically doing this every frame anyway.

[trim matrix]

I think I remeber going through a tutorial ages ago where a camera manager was used

[faint pasture]

Projectile movement component has a homing mechanic built in

[kind estuary]

which one do i use to update scores in the widget

string is not because its for when you need to change it

text or name

[ancient heath]

But I want the projectile to go straight

[kind estuary]

its the name

[dawn gazelle]

Name is meant for unchanging text based values. Good for human readable identifiers.
Text is meant for anything being displayed and can support localization. Most text that is displayed in widgets use the "Text" type.

[hardy tide]

Untick gravity on the projectile movement settings

[kind estuary]

yup thats what i used thanks

is this correct?

im getting my score using get text convert it to string conver tto float
then add in

[faint pasture]

You just said you want to direct it to where you are looking

what do you actually want?

You can direclty set velocity if that does what you want

[dawn gazelle]

Your widget shouldn't be in charge of holding the actual values of these things.

The widget should be used to represent the value stored on the actor that would actually be using these values.
Also you're opening yourself up to typos and mistakes if you're switching on Names. You're better off using GameplayTags or Enumerators if you absolutely must have a generic function like this, otherwise, you may as well just have separate functions that update what you need.

[ancient heath]

I made a line trace by channel that comes from the camera, and I would like my projectile to go where the line trace is looking

[faint pasture]

Projectile velocity would be in the direction Normalize(TraceHitLocation - ProjectileSpawnLocation)

[mystic panther]

This a bit specific but I'm struggling to find anything.

Does anyone know how to use the real-world time to create day night cycle? So like if the real world time is 3pm, it would set the sky to look like how 3pm would look. I dunno if that makes sense or not

[kind estuary]

thanks. got it. so basically the widget should just receive and i calculate the munition lowering in the actor itself? or the controller? or the player state? its too many options dont know how to decide sometimes

[flat coral]

Be careful with that because you can end up in Animal Crossing territory where players are constantly changing their device time settings to cheat the game

[dawn gazelle]

There's a plugin in the engine called Sun Position Calculator. Give it a lat/lon and time, and it can set the sun position 🙂

[mystic panther]

I'm aware of the pitfalls and it's not a big deal for my project. I did not know about the plugin so will definetly check it out!

[dawn gazelle]

Yep, wherever you may be storing the value, the widget should read from.

[kind estuary]

where do you store it? player state? controller?

ok

[dawn gazelle]

Depends on what you want it to be a property of.
PlayerState is usually a bit more useful for multiplayer, but in single player controller or playerstate are interchangeable.
Things like "Health" though sounds like it's more related to the Pawn itself rather than the controller or playerstate.
"Munition" sounds more like a property of a weapon rather than a property of any of the standard player related actors.

[ancient heath]

I understand that I have to modify the Projectile Velocity of the Projectile, but I don't know what Direction Normalize is

[kind estuary]

so maybe the munition should actually be in the BP_Gun

and the health in the BP_Character

And then things that are more general of the player itself then on thats on the PlayerState

is this correct?

[dawn gazelle]

Yep 🙂

So then in your UI to display the munition value, you may have a property like "Equipped Gun" on your pawn that stores a reference to the BP_Gun they are currently using, so then you can get the owning player pawn, get its "Equipped Gun" property, and get its "Munition" value from there.

[kind estuary]

yep thats kind of what im doing

whast confuses me too is that im trying to do something similar with the tanks i control

so my player has 3 different tanks and switch between them like you would switch weapons

so that means i must spawn them everytime i switch

or what do i do

set visibility?

i tried using visibility, but the actor is still there

in the tut i saw he was switching weapons and they are child actors in the character

[kind estuary]

makes the ones not in use invisible iirc
though i cant do that for tanks

[crimson prawn]

Hello I want to turn off/on a sound but if my new volume multiplier is > the current volume multiplayer it will not change. Is it an issue ?

Volume multiplier variable will have a value of 0 or 0.5 (I've tested)

[lunar sleet]

I don’t rly understand what you mean, there’s no stop sound in the code you’ve shown but maybe you should ask #audio

[crimson prawn]

Stop sound will reset, I dont want because I'm doing a kind of radio

[lunar sleet]

So you just want to lower the volume ?

Might be AdjustVolume node but #audio will know for sure

[chilly jacinth]

is there a way to get dynamic material instance from camera modifier's post process materials?

[noble ledge]

I have a project that has this bit of blueprints in it. Both of this variables are passed into this function and not by reference. Does that mean they are not being update correctly?

[crimson elbow]

Any logical reason why a lineTrace would work on one map, but the same lineTrace, with all the same objects and code, not work on another map?

[lunar sleet]

https://forums.unrealengine.com/t/what-does-pass-by-reference-do/303371

[lunar sleet]

Bad collusion settings

[noble ledge]

I know what pass by reference means but I dont know if blueprints do any weird things

[lunar sleet]

I don’t think so. But I linked that because it says to mark the function’s inputs as pass by ref

[noble ledge]

Yeah which is my confusion because in this project the variables are not marked as pass by ref but then those "by ref" nodes are being used. So not sure what is going on.

[lunar sleet]

So is the original value not changing or have you not tested ?

[noble ledge]

I haven't tested. I have loads of things going on in this project I would need to create a new one and test.

[lunar sleet]

Afaik those set by ref nodes should do what they say, but I can’t check rn

How can I check in code if a component is using Simple or Complex collision?

[humble turtle]

Hi folks. I could use a big hand... I need to change the material of static mesh "A" by clicking on static mesh "B". I've been through so many tutorials over the last 3 days and none of them exactly address the proper steps. Any help would greatly be appreciated!

[trim matrix]

It will take me a few

I'll do it

[frosty heron]

Get ref to static mesh b get the material. Set it to static mesh a material

[humble turtle]

Thank you very much.

[trim matrix]

Ok IDK how you want to click but i have a code that will explain in a nutshell so the element Index you can get from pressing the static mesh in the editor in my case i will be changing "palette" to: "door poop" element 0 is pallete

3 images to explain

the elemnt index is on my right

[trim matrix]

Thats it in a nutshell I guess

[humble turtle]

I think I understand the logic. Although, I'm not using a character blueprint (only a static camera and a mouse cursor).

[trim matrix]

It'll still work just ignore the rest

[humble turtle]

OK great. So would the Event Graph be under Level Blueprint, or something else?

[frosty heron]

take out level blueprint from your dictionary

[trim matrix]

Cold summer is right

[humble turtle]

Just to clarify (and please excuse my naivete), but assuming that Static Mesh "A" is a button, should I be creating a BP_button blueprint, then placing the button static mesh inside, then putting this code in its Event Graph? Because it seems like doing that would prohibit me from assigning the target as Static Mesh "B", as it only can reference itself. Correct me if I'm wrong.

[solemn basin]

can someone help me with the mouse button's? I'm trying to spawn a widget where i click and I cant figure it out.

[bright frigate]

Why don't you just have two meshes in one blueprint - one is static mesh A, the other is B.
A is visible from the start, when you interact, swap A with B (set one visible, the other invisible).

Otherwise in event begin play, store a reference to wherever you have static mesh B (if it's in another blueprint), then use that saved reference as the target.

[humble turtle]

Thank you, I’ll attempt that as well. Sounds very doable.

So if I do that, and there is a button (static mesh) driving that swap between static mesh A and B, I imagine I need the button to be inside a blueprint, with its event graph containing something like On Actor Click (or Left Mouse Button) and then a node to drive the swap between static mesh A and B?

[bright frigate]

yup that's how I see it essentially

[humble turtle]

Great. Thank you, sorry for the lack of proper terminology. I can visualize the relationships, but I struggle to know where to place these nodes.

[bright frigate]

your BP is your class, for doing swaps that don't need anything external, you can have whatever you need within one BP and just swap out things. As an example, I made a streetlamp for my earlier project but I wanted to keep one blueprint and just change its light-type based on a checkbox exposed to the editor. So I just put all the lights I wanted (cone, sphere whatever) in one BP. In the construction script, I checked which light was checked. Whichever was checked, made that light the one visible and set/active while the others were disabled and hidden.

[bright frigate]

yea I'm like you. It just needs you to immerse yourself enough where you're speaking in the language of the engine. Soon this will be easy and a complex project will make you feel this same lost feeling, but with talking it out you'll see solutions in your head.

[humble turtle]

Awesome, thanks for understanding. Maybe I’ll be back tomorrow with some progress. I appreciate everyone’s help.

[bright frigate]

if you need any help and don't get a response send me a message and I'll try to see, can't promise a timely response but I'll try

[humble turtle]

Thank you!

[fiery tiger]

How can I check if the instance of and object is index 0 in an array? I'm trying to make that check and then destroy it if it is.

[edgy ginkgo]

is there a way I can change an active player's player index?

I have an endless runner style map for my game where player's each exist in lanes but when they are close to one another they are able to switch lanes with each other

[edgy ingot]

What is the variable type of your array?

[bright frigate]

anyone please? My mesh simply does not appear as long as I have auto possession (or possession from any other way) of it. Never had this problem before

[fiery tiger]

An object array referencing a blueprint. Essentially I'm spawning and destroying tiles but I want to ensure that the one that gets destroyed is index 0. The way I'm doing it I can't just say get index 0, it's conditionalized among other things.

[edgy ingot]

Show codes

How you spawn the tiles

And how you are trying to get the reference

[fiery tiger]

sorry, took a second to clean it up so it was easier to read.

[edgy ingot]

Its too small for my phone. Can you just screen shoot the code to spawn the tiles

[fiery tiger]

@frosty heron Sorry! The issue I'm trying to solve is when the player turns around and goes the other direction, it deletes the wrong tile. I always want to delete the oldest existing tile.

[edgy ingot]

Well i dont know how the tiles are generated

Shouldnt they be generated at the start?

And if they do how r theh generated

From one line to other line?

In any case you should know which tiles is the start and forward since u spawn them

Oldest tile would be the first index

Last tile would be the end

[fiery tiger]

I may think on this some more. The way I'm spawning in the tiles is based on the players distance to their spawn point. I do it this way so that tiles don't delete directly behind the player and will instead wait til they are a full tile distance away. The issue with that is that if they turn around and go a full tile distance away in the opposite direction then it deletes a tile that the player needs when they turn around and go the "correct" direction. Which is why I'm trying to figure out how to check if the tile to be deleted is actually index 0. If I just say "delete index 0" then the player will fall forever.

I know what I'm trying to do is a lil specific and probably the wrong way but I'm learning >_>

[edgy ingot]

Only delete the oldest tile after the player went past the area

I would have a trigger volume instead checking range

Each tile set will have an end point, when the player overlap. Do the remove

[fiery tiger]

yeah I might have to revert to something such as that. I was originally doing that but for gameplay reasons went with distance

[whole hill]

Can anyone help me with this please?/Or have any good tutorials on how to import the Unreal Engine 4 shooter template to Unreal Engine 5 (5.3) without any errors as because I'm following tutorials in ue4 but I'm doing them in ue5. Help will be greatly appreciated.

[lunar sleet]

Why not just start a fresh fps template in 5.3?

[whole hill]

because I'm following tutorials in ue4

[fiery tiger]

You were right. I was WAY over thinking this and I got the behavior I wanted by setting a collision 12k away. Ugh.. thank you for planting that seed into my brain, it just took a while to fully process.

[fiery tiger]

I would suggest starting with a template in 5.3 and not porting one over. If the tutorial you're following was made for UE4 you're likely going to run into more issues anyway. The good news is that it's all a learning opportunity to google how to do the thing that's being described in the tutorial.

[whole hill]

It was like some really advanced AI thing the AI will flank you and take cover similar to how to combine do in half life two

Not sure there’s any alternative to that in unreal engine five though

Not sure I’m allowed to post the tutorial though

[dark drum]

The template in ue5 is setup to use enhanced inputs. (Which you should use if starting a new project) other than that it's pretty much the same. (Afaik)

[lunar sleet]

We also have an #gameplay-ai channel, I recommend watching the 4th pinned link there to learn BTs and EQS. Most tutorials you find from randoms on YouTube are crap, sometimes sprinkled with a bit of decent info, if you’re lucky. Mainly because they’re made by amateurs looking for views. The stuff on the Unreal learning portal, Mat Wadstein videos and maybe Ryan Laley (tho he has a cringe intro) are the exceptions

But you don’t rly want to stay in tutorial hell long, you’ll learn better by trying to build something of your own than copying some random guy’s code to make what he wanted to make (speaking from xp)

[edgy ginkgo]

I have a line trace that when hitting another player character it is meant to display a widget, however this line trace never seems to hit, any advice?

nvm solved it lol

[crimson elbow]

Its an exact copy from L_InventoryTestMap. Everything works fine in that map. If I move it to another map. The line trace stops hitting.

[kind estuary]

i have a character that has many cars. and he can switch between cars (like you would switch between weapons).
so lets say i have blue lambo and want to switch to red ferrari. How do i switch between them?
Do i set visibility to the to blue lambo to hidden? And make red ferrari visible? Or i destroy it and spawn red car?
Or i just set skeletal mesh of the red ferrari, and update all the variables of the actor to correspond to the red ferrari?

Its 3 options. 1-Visibility, 2- Detroy/Spawn, 3-Set Skeletal mesh

[dire frost]

the solution depends on what bottleneck you want to avoid. do you have a memory bottleneck? maybe too many cars to change between them? then visibility is out of the question and 2nd/3rd (they're the same basically, just one is harder to code but is little faster) option might be preferred. are the cars too slow to change? (either by spawning or changing meshes) then the first option is preferred

[cunning flume]

Finally figured out level stream instances. You have to first create the instance with the new name and then load it like a normal stream level. You would think after you create an instance of something already in memory it's "loaded" but nope.

[steady night]

Hey

https://blueprintue.com/blueprint/1bjq58ze/

im trying to check if "Enemy target" is infron on player*

based on player rotation not forward vector i suppose

what do i need to do ?

[kind estuary]

The thing is that each car has damage and weapons/ammo specific to the car. So if i destroy it just to change to the other car, but then need to get it back, then i need to load back all the little variables belonging to the car

Set visibility will hide the mesh but wont hide the collision and other things

And Set Skeletal Mesh only changes the skeletal mesh, so id still need to change the variables of damage, weapons, munition etc

So now im thinking on a 4th option. That is just moving the car to a location on the map. Like -1000 in the Z

and get the other car that is in the position -2000

This way all the data inside the actor is preserved

[minor wolf]

is anyone having issues with Get Game Mode > Restart Player? if i destroy my starting character and call Restart Player on my PC, i get a new pawn spawned in and the On Possessed function on the PC is called but my camera is stuck where my starting character was destroyed and i have no control over the new pawn

[minor wolf]

so the issue seemed to be with me doing the restart inside of the character blueprint. moving the respawn logic to the gamemode has resolved the issue

[sweet silo]

i have this throwing plank mechanic
how could i make it so that i have some preview of where the plank is going to be ? thanks !

[narrow pawn]

anyone can help me with a blueprint algorithm to feed my array of widgets with an integer?

but like, not all at the same time, rather starting with the one with the most value on one integer, till it hits 5, then going to the next element in the aRRAY

[coarse grove]

you can use a decal material to show a "shadow", can be coloured or not, depending of what u want to be

[sweet silo]

oh cool i didn't know taht

how do you do that ? just adding it as a decal in the bp?

[narrow pawn]

I'm confused

how do I get the Integer from the Elements in the List?

[dire frost]

do what works for you cause there's not really a "correct" solution 😄

[narrow pawn]

does that loop through the elements of my list?

[dire frost]

just use a for each loop

dont need the old ancient C way 😄

[narrow pawn]

My C++ is mad bad, wish there was some python or java interface in unreal lol

[narrow pawn]

I like that way more lol xD

[eternal cradle]

you should use a foreachloop and the index from that :)

[dire frost]

technically there's as a python interface but it's only for in-editor interactions

[narrow pawn]

That actually works lol

it gets my variables, I'm in love

[eternal cradle]

[narrow pawn]

so the for each always starts at Index 0 of my list, right?

so I can technically ask if <=5 ++1

?

[eternal cradle]

right

[narrow pawn]

how do I get a setter method here for the variable of that Element?

[eternal cradle]

pull out of the array element

set monsterCountStone

[narrow pawn]

I love you

[eternal cradle]

🤣

[narrow pawn]

hmm, it somehow doesn't work in the game

time for debugging

[eternal cradle]

is the Max Stone set to a value?

[narrow pawn]

for some reason it also doesn't print me the string at the end

[magic parcel]

New to BP, dont flame me!!!! However, I used a SetTimeByEvent node... and I cant seem to pause it

It just keeps firing every wave duration delay

I am thinking maybe I should put the pause and unpause branch at the StartEvent node (before the SetTimeByEvent) fires.... and that might be the trick, but not certain

[eternal cradle]

You are not setting the "wave timer handle" to be the timer you start

[magic parcel]

So this?

[eternal cradle]

yeah!

[magic parcel]

testing now!!

[eternal cradle]

that means its returning false on the branch, hmm

[narrow pawn]

woow, I actually didn't even think of that

[eternal cradle]

you probably want to set the Monster Count Stone before the branch

[narrow pawn]

I actually didn't set the value in the origin widget when constructing, I shall try that

[magic parcel]

Works like a charm!! Thanks

[narrow pawn]

still returns false

[eternal cradle]

hmm

[narrow pawn]

actually doesn't even return false, weird

[magic parcel]

can you put in a break and see where it is getting stuck?

[narrow pawn]

I know that Add Child deffinetly happens...

[narrow pawn]

I shall try

[magic parcel]

Also, I was using a for each loop to do my spawner.... and then I found out about the timer node

not sure a timer node works for you here, but.. maybe? 😛

[eternal cradle]

click on the foreach node and press f9 to add a breakpoint, see if that executes

[magic parcel]

Also, why isnt your shop variable an array?

[eternal cradle]

also as I said, perhaps you want to do mounstercountstone +1 -> set(monstercountstone) before the branch

[narrow pawn]

I use it to get a refference to the array initialized in the shop widget

[magic parcel]

ah

[magic parcel]

makes sense

nesting within nesting... scary!

[narrow pawn]

it did take me ages to get to this :,)

[narrow pawn]

maybe this is wrong? no?

maybe the array is empty, thus the for each loop isn't executed

[magic parcel]

lol do a foreach loop print string to say what is in the array! LMAO

[narrow pawn]

it deffinetly adds things into my array

also, what does the break point tell me?

Nothing happens

[magic parcel]

when you play

if it reaches that node, it will pause the editor there

and you have to resume to go past it

[narrow pawn]

ahh

[magic parcel]

this tells you, the code is executing that element

[narrow pawn]

well, it didn't xD

[magic parcel]

if... when you run, you dont get the break point, then its not getting to the for each loop

[narrow pawn]

I put a break point on my add child

[magic parcel]

give me the big screenshot again of where you break point is

[magic parcel]

put it on the branch

[narrow pawn]

the add child breakpoint doesn't happen either

nope, nothing

[magic parcel]

where are you calling the on clicked?

bound to the ui element?

on the widget?

[narrow pawn]

well, I made the summon widget a child of my GUI widget

and it is collapsed within my GUI widget

[magic parcel]

do you hear the sound?

[narrow pawn]

yes

[magic parcel]

put a breakpoint there

[narrow pawn]

wait

do I?

yep, have sound

[magic parcel]

so you get a breakpoint with the sound

hit resume, and then nothing else breaks

[narrow pawn]

it doesn't break lol

but it plays the sound

[magic parcel]

sounds like its being played somewhere else

and that the entire onclicked event is not running

do this

after the on clicked, before the sound, put a printstring, PLAYING SOUND

and unhook everything else from that print string

see if you see the string

[magic parcel]

okay, now...

put a breakpoint on the string

and see if it breaks

[narrow pawn]

nope

no breaking

[magic parcel]

.... well then that isnt good

[narrow pawn]

lol xD

[magic parcel]

cause that means the breakpoint tells you nothing at this point 😛

and the entire point of the breakpoint is to tell you how far the code is getting before it doesnt fire or gets stuck

[narrow pawn]

I can put the print string right after the loop

[magic parcel]

so, your for each could be working

put it before the loop

and after theloop

on says, ADDED CHILD and then the other says (after the loop) AFTER LOOP

see what happens

that is odd, I would assume breakPoints would work in UI stuff..... again, I am a noob and know very little

I just watch my coder do all the work and learn as I do 🙂

[narrow pawn]

yes, the Loop ain't happening

[magic parcel]

well, then look at this site and see if it helps.... (cause I am not good enough to guide you)

https://couchlearn.com/how-to-use-loops-and-arrays-unreal-engine-4/

[narrow pawn]

I'm fairly certain it is a problem with the Stone List

can i debug this smh?

[magic parcel]

Okay, well I wish I could help more, but I exhausted my knowledge level lol

[narrow pawn]

no worries, you helped plenty

appreciate you lots

gl with your game

[magic parcel]

thanks! same with you my friend

[narrow pawn]

okay, so the list gets expanded when I buy a stone habitat

but when I call for it in another widget it is 0

[dire frost]

holy, what a thread

can i get a tl;dr 😄 ?

[narrow pawn]

yes please

[dire frost]

what's the issue? didnt you just need to iterate through an array or something?

[narrow pawn]

so here I add elements to an array, and the array does get expanded

when I then ask in my main GUI how many elements are in the array...

it tells me 0

thus my for each loop doesn't execute

[dire frost]

are you sure you have the right instance?

[narrow pawn]

uhm

this is the only array in my entire game so far

there shouldn't be more instances

and the shop gets set visible and collapsed

[dire frost]

so this first print string...does it print what you'd expect?

[narrow pawn]

yup

[eternal cradle]

the problem might be in here. why are you using random bool with weight? this will cause the branch here to be 50% of the time true

[narrow pawn]

oh yeh, I always press multiple times

[eternal cradle]

ah :D

[narrow pawn]

till I got both events to trigger a couple of times as well

[dire frost]

yeah so the array wouldnt get emptied on its own. so either you have the wrong instance or you are emptying the array somewhere

[narrow pawn]

Could set it to 0 for debugging

[narrow pawn]

I check if it gets emptied

nope, doesn't get emtied

I will record what is going on...

its so weird

[dire frost]

yeah use tick and keep printing the array length

pro-tip: expand the print node and for the key type "my arr length"

this will prevent it from printing the same print with the same key twice on the screen

[narrow pawn]

I put a button on my stone widget that will print the array length

so it apparently is the wrong instance, as your gonna see in the video in a sec

but the pressing question is WHY

[dire frost]

for the instance that has the empty array. how are you setting its reference?

[narrow pawn]

it is executed in the GUI widget, but Shop is a child of that Widget

Summon is a Child of that widget as well

https://tenor.com/view/crying-emoji-gif-21922016

[dire frost]

you never actually set the reference in this code snippet

[narrow pawn]

do i have to?

[dire frost]

yeah

[narrow pawn]

the array is from this widget

what do I have to reference it to?

[dire frost]

im surprised it didnt scream Accessed none error at ya

[narrow pawn]

I'm clearly a noob, I don't even see it

[dire frost]

maybe because it runs on its own process 🤔 can you play your game in PIE?

[narrow pawn]

same issue in PIE

[dire frost]

and FYI, that error means you are trying to access data from an instance that is null (doesnt exist)

[narrow pawn]

but why is it null, its initialized, innit?

[dire frost]

hmmm can you search for all references to that reference? just right click the option should be there

[dire frost]

(good one) is it tho? you never showed that to me 😅

[narrow pawn]

AHAHAHHA

at least in PIE I get screamed at

[dire frost]

oh here we go!

yeah so you'll want to initialze that reference

[narrow pawn]

how

I thought what I did initializes it

[dire frost]

hold alt and drag that variable from the right to the graph

[narrow pawn]

that is so weird, like it allows me to get the reference but it won't initialize it?

[dire frost]

that should make a "set" node

[dire frost]

i mean how would it know if it is set before or now?

[narrow pawn]

upon Event Construct?

[dire frost]

ye that one

[dire frost]

yeah now you'll need to grab the reference to the shop somehow somewhere

[dire frost]

oh god please no this is cursed af

[narrow pawn]

I figured

[dire frost]

so what is Shop again?

[narrow pawn]

one of many widgets

[dire frost]

hmmm alright....

where do you create these widgets?

[narrow pawn]

in GUI

I mean

no

I create GUI

[dire frost]

ok phew

[narrow pawn]

Shop and Summon are children of GUI

[dire frost]

so it's not scatered around that should make things eaiser

[narrow pawn]

GUI is initialized once

in the LevelBlueprint

[dire frost]

ok so Shop is a child of GUI?

like a child in the OOP way

[narrow pawn]

uhm

no

I just dragged the widget in there

[dire frost]

oh...alright

[narrow pawn]

nobody taught me how to make a widget the child of another widget

but if that isn't it, then what is lol

[dire frost]

in a user interface way that is a child

[narrow pawn]

deffo not object oriented though

[dire frost]

but in the programming world a child is something that inherits from a base class

[dire frost]

yep.

there's a lot of resource online that goes into detail

but tl;dr you can use a child as a parent but the parent cant use a child

[narrow pawn]

but if I make Shop an actual child, GUI won't get the array either, right?

[dire frost]

more or less

[narrow pawn]

oh yes

I remember, good old coding

[dire frost]

if the GUI has the array already then the array wont go away

in fact the shop will also have an array

[narrow pawn]

means I will make the Array in GUI

[dire frost]

yeah. well this isnt programming 101 so let's focus on getting a proper reference to the shop 😅

get the shop and use a isValid node

on false put a print and add a breakpoint on it

just double checking if it's actually null

[narrow pawn]

working on it :D

IT WORKS

OH MY GOD

I mean, kind off

it for some reason went on above 5 and then set all the values to 6

but I guess I can work around it

it is kind of buggy

but well

tysm for your help

[dire frost]

wait a isValid check fixed it? well go me lol didnt know i was that smart

[kind estuary]

@dire frost did you read this?

[dire frost]

no must've missed it 😅

just a sec

[dire frost]

actually you can just disable collision and the other things

[dire frost]

i mean that could work, the latest fnaf game pretty much does the same thing for your player but as the game shows, the approach is super inconsistent

[narrow pawn]

even got rid of the buggy thing going over its limit

wonderful

love my life

[kind estuary]

why is it incosistent?

the car would be hiding below nobody can see it, its just because its more convenient

so when i need that car i just get it into position and put the current car below

[remote meteor]

what is the outcome for? 1>1.5>0?

[silk hinge]

hey, So I been reading this again, I understand better how it replicates then, TY

This means I need a more versatile way of replicating my AimOffset, in a way that everyone will have the info about where is everyone looking at ^^
I dont exactly know how I'm gonna do that tho.
I there a way to just replicate properly the "AimOffset" node from the locomotion system ?

[dire frost]

you could check out the latest fnaf glitches videos. but if it works for you and it's actually consistent for you then go for it!

[hallow patrol]

IS there better wsy to check if player is between 4 points? This not working well

[versed sun]

there is Float in Range

[sour crater]

trying to convert this progress bar into a Text string display instead. The Get BP function is attached to the Percent bind

whats the easiest way to do this

[frosty heron]

you make another Text Widget that represent the precentage

"Current Value / Max Value"

[sour crater]

that wouldn't be a new widget all together right

just drag out text to the UI?

[frosty heron]

no, you just drop a text component to the UI

[sour crater]

XD

all good im just too novicey need to check

[sour crater]

what do i bind it to?

[frosty heron]

what ever you want to

[sour crater]

i just want to display the BP stat

[frosty heron]

then bind it to the BP stat

[sour crater]

-w- i mean

what do i bind it to

the function

in the textstring

[frosty heron]

you bind it to what ever you want

you said you want to bind to your bp stat

[sour crater]

it will just work?

[frosty heron]

so bind your bp stat

[sour crater]

binding it to is enabled will work then?

[frosty heron]

I suggest to just start doing it and see for your self

[sour crater]

fine

[frosty heron]

cuz I don't even know what you want to bind based on the picture

what you want to change from the text is obviously to set / bind the value to w/e you want

not the vissibility or the is enabled or the tool tip

[sour crater]

I am really new to widgets, im better at bps. I just need to know where to code the function in

[frosty heron]

you can set normally like what you would do in a normal bp. or you can set it with function

^ Like this is function

[sour crater]

Yes, but having this function within the progress bar does not make it work within the the text UI widget

i need to know how to get this function, into there

[frosty heron]

You would do the same way you do with how you make the function for the progress bar

except it's for the text you dropped

[silk hinge]

I would have create a volume in the map, and use the "overlap" of this volume to send info to the server that someone is into what ever Area

[sour crater]

bind it to percent

?

[frosty heron]

bind it to what ever you want

if u want the text to show the percent then so be it

if you want to show a Current Value/Max Value, then get the data from your bp

[sour crater]

let me see what i can do

k i think i got it

to answer the question

i binded it to text

new error

0.16 is suppose to be 16

[frosty heron]

not really

percent is 0 to 1

if you want it to be 16, make a new function

do the same but multiply by 100 before the output

[sour crater]

let me try

thank you

[teal lantern]

I'm trying to spawn an actor but nothing is spawning. I can't even find it in the outliner when I play my game. The spawn location is supposed to be near the actor that is spawning it.

[small rose]

Have you checked if the spawn transform location is correct? Try printing that out to the screen

[elfin hazel]

It could be inside the object, though with your collision override, it may not be spawning. Change it to something else, like "always spawn, ignore collision".

[teal lantern]

yeah it was inside the object. I didn't know there was a check to see if it spawns inside an object

[sour crater]

I love it when you break through your errors, and then you get to code seamlessly

(until you make your next error)

whats missing at the end of the BP +

its not working and i think im missing something there

wait maybe ill set

instead?

right

i need a set?

[dire frost]

yeah you need to set the var

[trim matrix]

guys how can i pass only one variable based on the string i take from the variable?

[dire frost]

first, convert the string to a name. then ig you can switch on the name?

[versed sun]

or , change Ammo Type from a String to an Enum and Select

[trim matrix]

for that i create an ENUM bp?

[fiery ridge]

Why is it not possible to have a Delay or Timeline nodes in a function library? I just want a global custom function across all blueprints, preferably with timer logic

[sour crater]

not sure why its not working

[versed sun]

yes

[dry sleet]

Functions can't be async in the event graph, but macros can.

I don't like macros myself but you can do what you want with a macro library instead.

[vivid marten]

SetTimerByFunctionName ?

[fiery ridge]

Can't make custom event to connect it

[fiery ridge]

I'll look into thay

[dry sleet]

Hmm, on second though I think delay nodes will work but timelines maybe not.

Since I believe they add a component?

[fiery ridge]

Whatever timer logic works im ok with it

I just need a global function with timer for easy access

[remote meteor]

depending what the timer is used for

you can place it in GameState or GameInstance

[brittle canopy]

Hi guys, I have a combat where I’m melee attacking the target actor and at the first attack the camera rotates to face the target actor .
I have to things that currently aren’t working smoothly for me:

1. When I hit the target actor the montage that currently playing is overriding the desired rotation and slightly misses and not aiming directly to the character, I want to get the every hit the character will rotate to the target actor exactly and will magnet to it.
2. I want to add another layer on this system that performs a direct attack and rotates the character to the target actor when the movement input “aiming” to the target actor.
   Can some of you please help or direct me to the way I can perform and execute this visions?

[silk hinge]

you would need those to be a projectile class not just an integer, or make it a map with string + Interger, but maps are not replicable

your project looks to have the wrong setup to handle this type of system

you should probably have a structure per item, and this items struct holds :

Item type
Projectile Required
current ammo
max Ammo

etc...

Then you could get the projectile required and compare the classe to see if it match the Item type of the bullets, or something like that.

In all cases you wont be able to do what you want with integer

[sour crater]

Im having a error when im adding a second text block for my newest stat im working on,.

Get Knowledge Unable to bind DoubleProperty, Unsupported type

what does that mean?

nevermind

figured it out

had to use ToString to make a float into a text string

[undone surge]

i have this piece of code that i want dynamic for all my child classes. is there a way i can dynamically cast to the child class's anim bp instead of the parent one. can i like store it in a variable or something

[sour crater]

yes but you cant call parent functions or vars

i think

ask more people

[undone surge]

hmmm

[fiery ridge]

yes, thats the whole point of children

but you have to make them into variables

just promote things that you wanna change into variables in the parent

[undone surge]

bbut the cast node would be diff right ?

if i want to cast to another anim bp

[fiery ridge]

i havent worked much with anim bp but im assuming your parent bp has an anim variable?

[undone surge]

the one at the end is a variable with the ref to the pawns animation bp

i want to change it so that for each child bp it casts to that childs anim bp

[fiery ridge]

if i understand, yhou want children to have different anims?

[undone surge]

yes

i have a different animation bp for each child

[fiery ridge]

then change it on the child, no need to dynamically change it

[undone surge]

alright

thanks ill try that

Hello i have a simple problem, i am running two unreal engines projects on the same pc but when I am inside in one of them the otherone drops down on CPU usage. (I have already uncheck the checkbox that says use less CPU on background in the editor preference)

[amber spindle]

Hey, I need to check if player walks by specific location but looks like Line Trace doesnt see character. What should I use to make stuff like this?

[silk hinge]

you gotta change the collision on the mesh so it can get hit by a line trace, but if it's specific locations into a pre made map, I would just create a collision Box with an actor I can place where I want and re-use

[plain inlet]

Hi All! Does anyone know a problem with Line Trace by Channel when setting Draw Debug Type to anything regardless none. My complete application crash + UE Editor. If Draw Debug Type is none it works. Argh. Its a VR Environment.

Nothing special :/

Hello, I'm having a problem with the "Add to player screen" node for a splitscreen project. When I use it I am no longer able to interact with the widgets and they don't even scale well. If anyone has a suggestion I would be grateful

[crystal flax]

hey guys i need some serious help i have to submit a project in 2 days i have to create a game my character faces some situation and when the situation occurs there are multile option player have to choose any one no option is incroorect but every option have diffrent scoring as player progress in story they get more question and they select the option at the end the score is calculated can any body tell me how can i do this is there any tutorial or template avilable for this which can help me

[vivid marten]

nothing like waiting until the last minute to do something.. I am sure a quick google search for "unreal engine choose your own adventure" would likely have some results for you to find a tutorial of some type

Good Luck and I hope you get it figured out

how do you create a skeleton mesh from a skeleton, i have a rover that i want to convert

[hallow mirage]

does anyone have any idea how to fix a corrupt Blueprint which is caused by a node in the pre construct event? I tried to plug a button style into an inputkeyselector on pre construct and saved over it (dumb) and now I can't recover the Blueprint. Disabling the "Execute Pre Construct Event" check in my editor preferences allows me to open the project with the blueprint in my contents folder, but it's an immediate crash every time I try to open the Blueprint. I'm wondering if there's some way I can delete the button style variable altogether by editing the uasset file or something

nevermind, hooray for Unreal Engine autosaves

[thin panther]

no. hooray for source control. set it up now

[hallow mirage]

I perforce most projects but this is like

the mini-est of projects

and I am lazy

lol

[thin panther]

it's barely any effort

laziness isn't even a good excuse lol

[hallow mirage]

The max risk I'm probably running is like an hour of lost work

[thin panther]

not if the project itself is screwed, and your autosaves aren't there to save you

[hallow mirage]

my perforce keeps getting clogged up with my mini projects ugh I might just nuke it

[thin panther]

then use git :P

[hallow mirage]

No I mean like, the project is literally me just making a key rebinding menu

[heady burrow]

How would you about making an actor appear through a portal, in a way that its only visible within certain area of the level, sort of like ships in Homeworld pop up.

[glass vale]

hi there. would you you guys know why does 5.3.2 crash on reopening the editor and also doesnt package if I have a game instance bp, and it crashes with this eror message
appError called: Assertion failed: Linker [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp

[quartz mural]

Can I put a wildcard in slots I don't care about? I want to see if there are any remaining items of rarity 0, but don't want any of the other data to influence the filter.

[deft cobalt]

hi all, i'm trying to figure out how to make a component add a dynamic amount of subcomponents. within the component blueprint, however, i can't seem to add a component. how do i add subfolders of components like seen here:

[humble turtle]

Sent you a message if you have a moment. Thank you!

[deft cobalt]

to add some more context - i am looking to place patrol point actors throughout a level, then bind them together by setting their signature variable to the same number. then, if an NPC actor has a "waypoint set" component, it will look for all waypoint actors of the same signature and get their locations to be used as coordinates for the NPC AI to pathfind between. i was planning on implementing this as a dynamic number of child components of the waypoint set component, but i don't know how to do that

[hardy bough]

This may be a dumb question.. I'm a C# developer by profession, just been diving into unreal and mostly doing blueprint stuff. Eventually going to start doing stuff in C++, but anyway... is there a way to query an array of structs for a specific value in one element? I know there's a Contains but it searches for a perfect match for all elements. In C# I would just use a little linq & lamda to query the collection for whatever property values i'm looking for. Struggling to find something similar in blueprints

[gentle parcel]

Hello fellow slackers. I see there's a lot of activity so I hope I can have still a little help. I have this problem with a component I'm making updating an older project and I have this problem right down below. How do I get that Duration value in Play Montage, in order to get rid of Play Anim Montage without breaking the code!??

[marble tusk]

You'll probably have to loop over the array and check each index individually

[lunar sleet]

I think we’re technically “sourcers” now. Not sure what you mean by “without breaking the core or what exactly the problem is. #animation might be better at this stuff tho

[gentle parcel]

Slackers still sounds too cool to lose that habit that quickly but yeah 😅 Anyway, I thought it was more a blueprint structure thing than just about animation itself

[lunar sleet]

Maybe try explaining the problem again, it wasn’t rly clear

[gentle parcel]

I used the most immediate solution below but I'm not sure if the result is the same

But maybe at this point it does become more an animation thing more than just blueprint logic, I dunno

[lunar sleet]

Yeah montages usually are. Is that old node deprecated?

Can you add a track to it like with timelines? 🤷‍♂️

[gentle parcel]

I think it yes yes, because I couldn't find it anywhere, it seems it has really become Play Montage

Even if it does still work if used in the direct blueprint

[gentle parcel]

might be, if doesn't imply modifying each montage

Anyway... Ill make try as it is, hoping the character does get animated, because it wasn't anymore

I'm still not good in creating the reference to the character when building components

[eternal cradle]

Perhaps what you could do is thru the Default exec pin -> Set bCanMelee(false) and then thru On Completed + On Blend Out + On Interrupted -> Set bCanMelee(true)

[glass vale]

since i cant use game instance, since it crashes UE 5, and doesnt pacakge i m trying to use game state instead but that doesnt work either

[gentle parcel]

🤔 I'd try that one...

[eternal cradle]

what are you trying to accomplish? its not normal for the game instance to crash Unreal

[eternal cradle]

let me know if that works

[glass vale]

I will show you what I am saying here it is:

thanks! this is the error message I get when I cant package and also similar to when it crashes

....

complete package error log can be found here: https://drive.google.com/file/d/1EWKFJ1UpOVb68cVuh6VENaQkdrH389O8/view

this happens every single time i use a game instance in 5.3.2 when i restart the editor, same problem doesnt exist in 5.2.1. Also the same thing doesnt allow me to package
it has nothing to do with the bp. the moment i even mention game instance it immediately crashes upon reopenng UE editor

[gentle parcel]

It was making everything even more broken for some reason, but apparently this was a better option. Still dunno if it does work by the way... I get an error mentioning a variable I created in one of my earlier attempts but I cannot find any actual reference to that deleted variable anywhere

And the character still doesn't get the AnimBP working anymore since I created the component and moved the whole blueprint's combat section into the component.

[eternal cradle]

hmm, interesting

[gentle parcel]

when I click on CombatComponent there in the message it leads nowhere

[glass vale]

ok this is most unusual. upon repoening my level with game instance the editor crashed with the follwoing log. But at the same time UE editor is open. While there is a crash log. So it has crashed but i the editor is open and not crashed at the same time

[gentle parcel]

The fact we cannot select more variables at once to copy and paste them into another blueprint really goes beyond any logic to me... it makes things so damn tedious... I really don't get why there's not such an option. I would just make a new component and try fixing the problem that way but it's quite annoying to do everything one by one with dozens of variables

[eternal cradle]

structs are always a bit finnicky to work with as well

[gentle parcel]

All the issues come from the fact I'm doing something wrong when making the character communicate with the component, specially when it comes to play a montage or when generally communicating with the AnimBP.

I really wish I'd come to a solution for that which works with any component once and for all, but what I understood is that there isn't an unique way and there are several conditions to keep in mind when creating one.

I'm open to suggestions at this point, because I'm at the verge of getting desperate.

[eternal cradle]

I can't say much without seeing more of how you've built your system - are you using an actor component as your "combat component" or something?

[gentle parcel]

I'm using an Actor Component from the Blueprints Class selection, yes

Usually I do create components from an already made CharacterBP

I mean... I recreate in the AC what I have in the CBP, most of the times copying&pasting what I need to turn into a component

[quaint fable]

I'm a bit new to UE5. I've been trying to figure out how to make a wall become transparent only when the view of the player character is blocked. I'm using the top-down blueprint. One person said fire a trace from the camera to the player, whatever object it hits other than the player, give a material instance of a low opacity material... I also want to be able to have the cursor ignore the walls so that the character still goes in the direction I want. Otherwise, the Player character gets stuck

also I'm using geometry for the walls instead of a mesh

[dawn gazelle]

Not with blueprint structures. You must have all the exact values placed into the comparison nodes like this one in order to find a match. In C++ you can override the == operator and make it so it checks only specific fields.

[quaint fable]

So I have custom animations, that way when my character holds a flashlight, he has it pointed forward. How can I set these animations to the ABP_Manny?

[sacred forge]

I'm working on a system that updates the UI in a Widget Blueprint based on events or conditions in an Ability Effect Blueprint. However, I am having challenges passing information from the Ability Effect Blueprint (specifically, whether a hit was successful) to the Widget Blueprint to trigger an event or function there.

I've tried both event dispatchers and interfaces and I can't seem to get either to work. Any advice or assistance would be greatly appreciated. I can provide additional information or screenshare if needed.

[round marten]

hi, can someone explain to me why this returns false? i have no idea why is this happening, is it a bug?

they're the same value, and when i check with the 'is equal' node it returns false anyway, why is that

[lunar sleet]

Prly because of the floating point error. Try a near equal when comparing floats, computers are imperfect

Give it a small tolerance

[round marten]

wow ok that seemed to do the job, you're right, computers are imperfect

thank you

[dawn gazelle]

It's not about computers being imperfect, it's how floats work - they sacrifice precision to allow you to store virtually an infinite number of possible numbers within 4 bytes, so even if you have two numbers being represented as 1.200000 one could be stored as 1.2000000005 and the other as 1.20000000006

which means, they don't == one another.

4 bytes can normally only represent ~4.2 billion values if each bit combination is used to represent a single number.
Floats are 4 bytes long but can represent 1, 1.1, 1.2, 1.3, etc. 1.01, 1.02, 1.03, etc.. 1.001, 1.002, 1.003, etc. or 49582252.525, 49582252.526, 49582252.527... They're technically unlimited, but they will not necessarily contain the exact number you actually want to store.

[lunar sleet]

So technically… good but not perfect 🙃

[dawn gazelle]

yep. And actually I mispoke... UE5 made them slightly better as they're supposed to be doubles under the hood now, so they're actually 8 bytes long, making the numbers they can store even larger, and more precise.

[lunar sleet]

Is that what the double precision means ?

[dawn gazelle]

Yep

[lunar sleet]

Nice

[remote meteor]

depending where the breakpoint is, it may have just not been executed

[round marten]

it did fire, it's just that the value wasn't perfect, thank god neoexcidious was around

[empty gust]

how do i zoom camera for sniper aiming

[gritty wraith]

Why does my widget not detect mouse events?

[surreal peak]

Widgets usually have overrideable functions for this

Actual Input Events, at least by default, aren't a thing in UI

Epic did release something along with CommonUI to allow EnhancedInput Actions to work, but not sure how far that is

[thorny hatch]

still shows up in inventory even tho i set the array element index 0 to nothing

[dark drum]

You'll need to show what the loop is actually doing for help.

[thorny hatch]

yeah i fixed it, I used the helper function so i didnt modify the actual array

since GetItems is just for blueprint that just retruns the item array, Not the actual item array

[young meteor]

Hey folks

Might have a stupid question here.
How do I remove my saved game when playing in editor? Want to test stuff from scratch.

[frosty heron]

Delete game in slot node

The slot name is the name of your .sav file

[young meteor]

Okay, so I basically have to implement a bit of code in the game allowing me to do it?
Can't just do it from editor?

[frosty heron]

Why not?

what you mean by editor

u can play play in Pie and run the node

or if you want a custom button you can do that too with slate

so when u click that button it will clear the .sav files

slate is probably cpp territory

I would need to implement some to select my most visited map

[young meteor]

Me being lazy here.
Need what you suggest at some point anyway probably.

[frosty heron]

There is also editor utility widget

but takes too long to execute it imo

u have to run the widget in editor, then press a button or w/e

if u do it with slate, u can just have a handy little button at the task bar

[young meteor]

I was basically trying to avoid having a button players could press to just start over.
Alternatively I would "secretly" bind it to a key press and not tell player. Sucks if they hit that key by mistake though.

Figured there might have been some project setting etc. where I could just clear it

[frosty heron]

Why do the player need to know about the button?

or even see it

It;'s for u to use

you can run the node via development custom event

Or just have a slate widget ( a button in your editor )

[young meteor]

They don't. But if I bind it to "P" key for example and they hit it

[frosty heron]

you can run a custom event

that's how I do it atm

when I know how to use slate, I would implement custom button

but for not it will have to do

I will show you how I delete my save file for debug purposes, sec

[young meteor]

Thank you

[frosty heron]

Custom event in Level Blueprint @young meteor

replace it with delete game in slot

[young meteor]

Oh, like that

[frosty heron]

Yup, instead a button

[young meteor]

"ce" meaning?

[frosty heron]

Console only available in package mode

[thorny hatch]

This is when i drag an item over ainventory tile, Im just setting it to 17 now but it isnt working this is the result i get :

[frosty heron]

ce for custom event so . ce "YourCustomEventName"

[thorny hatch]

This is not index 17

[young meteor]

Got it. Thank you.

[frosty heron]

In shipping mode, player can't even open console. So it's all good

[young meteor]

Menu picture looks great by the way 😉

[dreamy gulch]

Got drywall punch inducing problem with an array removing entries or what appears to be removing entries out of the blue. Loops through in range actors and pick target, it half works then stops. It was perfect before. Then just decided to bug the fuck out. It should print looping through all entries for the full lngth but it does a few loops then stops. Weeks ive been trying to fix this to no avail to the point im going to have to restart the full project because i literally cant see how its possible that this is happening .

[random pulsar]

Hey guys,i created the crafting system when i drag an item onto another there is created an object and i want to control the amount of these objects like for example 2 sticks and 3 leafs will craft am arrow,and it works with 1 and 1 but when i put 2 and 4 for ex it does not work

[frosty heron]

When you are trying to remove something from an array with for loop, make sure to do it from the last index.
That said, use Reverse for loop instead

[random pulsar]

it just swaps the items

[young meteor]

Oh, by the way. Can it access this Custom Event from any BP or do I need to put it in a specific BP?

[frosty heron]

level blueprint only

[young meteor]

Thank you

[frosty heron]

Reason for me to do it there anyway because Load happend in main menu anyway

for me

[dreamy gulch]

im not trying to remove anything, its removing by itself but without removing it, it just stops existing in the array

[frosty heron]

Can always use Keys of course like what you said earlier. There are times that I do that but I end up shipping one of my release with it 😄

at least 3 times, I took down my build from the platform because I forgot to remove the debug

[young meteor]

haha, yeah. Can I access GameInstance instead of Level BP? I do my saving there.

Otherwise I'll just do a cast.

[frosty heron]

The ce command only work with level blueprint

[young meteor]

ok

[frosty heron]

if you want to use keys you can use your player controller

then u can pretty much do it from anywhere

[young meteor]

Right

[dreamy gulch]

I only add or remove via a sphere collider, which toggles the color of actors if they are added or removed from array. They are never removed, yet the array removes them

and it just started happening

[frosty heron]

well I can't virtually debug when I don't have access to the project but I never encounter an instance where my array just remove element by it self

[young meteor]

Am I stupid here? It's not popping up.
"DeleteSave" is in menu level BP

[frosty heron]

open the console when you play in editor

[young meteor]

Not sure how honestly

Set it to "O" but nothing happens

[frosty heron]

mine one is ` by default

[random pulsar]

Could someone tell me why it does not work?crafting with the amount

[kind estuary]

You have 3 types of bullets:
9 mm, 7.62, and 50 cal.
Each of these bullets cause different damage.
9 mm -> causes 30 damage,
7.62 -> causes 40 damage,
50 cal -> causes 50 damage,
Does that mean i should create a blueprint child for each different bullet?

[distant hollow]

If the “calibre” and the damage are the only parameter differences then you might not

You can have an Enumeration then set the values based on the Enumeration selection

[distant hollow]

Didn’t study them closely but it could be this

Try setting to => instead, or swop the pins

[thorny hatch]

What should i use for drag and drop inventory? Grid panel or what

[tall veldt]

Hi ! i have a grid like the image: I want the white sphere to be able to detect that he can walk a circle around the building. I have been trying out A* but that doesnt really work when start and end pos are the same. In this scenario i can just check if the neighbours are walkable tiles and just continue until I see the start pos again, but I also want more complex routes, with different intersections. Can someone help me figure out the steps I need to take?

[narrow pawn]

Am I using this Timer Handler right?

I want to set the boolean to false for like 3 seconds

[thin panther]

no you aren't

create a new custom event on that event pin, where you set the bool to false

[narrow pawn]

huh?

my event is on clicked

[thin panther]

the event pin is where you plug in what you want the timer to execute

[narrow pawn]

like this?

[thin panther]

so make a new custom event, where you set the bool to true, and plug it into the red event pin on the timer

[thin panther]

no

[narrow pawn]

like this?

doesn't work

[thin panther]

no

keep everything as it was in the first screenshot

make a new custom event where you set the bool to true and plug that into the red event pin

[narrow pawn]

I think I'm dumb

by that you mean the red pin from the custom event?

[thin panther]

yes, the event that sets the bool to true

[narrow pawn]

this is confusing

[thin panther]

you're ever so close, but you don't want to unhook the white wire from the other side of the execution pin
what you've got there is saying "set a timer for 3 seconds, immediately set the bool to true, then after 3 seconds set the bool to true"

[narrow pawn]

ohhhh

but this looks weird to me, the event comming out of the left side of the node

so I want to set it to false, set the timer and then after 3 secs to true

[thin panther]

you can move things whereever you want. you can also move the bool being set to true into a function and use a create event node.

basically that red pin is whatever you want to execute when the timer hit's the Time
Whatever follows the timer via a white pin is executed immediately after the timer is set

[thin panther]

that's what you now have

[narrow pawn]

ahh, I get it

tysm

[thin panther]

np!

[narrow pawn]

works like a charm

[timber crystal]

Hello friends...
I still have the problem that my Ai dont moves in the direction that i want if he sees me

its nothing special i try also the 2 ways but nothing work

[kind estuary]

its that and there's also a difference in the weight of the projectile and the projectile mesh itself.

other than that i dont know

[distant hollow]

If there is a projectile mesh difference then would be easier to create child classes

[strong rover]

Hey all! Quick question.

For a project I'm working on I'd like to have a big map.
GUIDs are the keys, strings are the values.

I intend to generate this map at game start, as the user can add their own options at runtime. So a static map won't work.
Is there an upper limit to how big you should make a map in blueprints? Are there better systems to use when you might be working with a few thousand variables?
The key thing is that I need it to be dynamic while also as efficient as possible.

Thanks!

[kind estuary]

yup else id have to go full data driven, create data table, and each one has its mesh, damage, and other stuffs

thanks

[ocean gate]

hi, I'm having troubles with optimizing my game on the cpu. I want to avoid using event tick in my blueprints as much as possible, however I can't think of a good way to do it. For instance I want to make my crate blueprints to not run their functions (gravity, burning damage and damage handling in general etc.) when not close enough to the player to be noticable. However, running a "distance to object" thing in event tick would arguably be even worse than just running these functions as is, right? Or am I wrong about this assumption?

[dark drum]

I've had map var with a few thousand entries before and it didn't seem to be a problem. Depending what you're doing, you can sometimes split it into smaller maps if needed but you'd probally be fine.

[dark drum]

Timer by event functions. Burning Damage and Damage in general don't need to be on tick and would normally be checked at time intervals or as a one time event.

[strong rover]

Aye-aye, thanks @dark drum
It's basically a live 'text' database that the player can maintain, to run alongside the actual localisation database for core functionality.
It's only called on event, no funny business.

[ocean gate]

Ah! So timer by event for checking distance to the player?

Or should I have it running inside the player and disable actors outside of a given range instead?

[dark drum]

No, to apply the damage. Applying damage on tick isn't necessary and would probally only need to be applied ever 1s if recurring damage.

[ocean gate]

ah I see, thank you!

Also, gravity is running a ray cast every tick as well so I would like to disable that if possible as well. Any idea how to do that as well?

[solid trout]

hey y'all, i have a blueprint function that takes an array of booleans as it's input, and there should always be 20 booleans in that list. i want to call this function in a cpp script using "CallFunctionByNameWithArguments", as i have done before, but i'm not sure what formatting it recognises for an array of booleans as the pass-in argument. anyone got any advice?

it sucks, but i could just make 20 separate input variables and call CallFunctionByNameWithArguments with 20 different argumenets, but that's terrible code practice

soooo is there a way to pass in an array?

[ruby cobalt]

how can I make a static mesh look at another mesh using BP?

is there a premade function for that or so I need a vector between both objects?

i found solutions for ABP but in this case it's just to orient a light actually..

[brittle canopy]

Hi guys, I have a combat where I’m melee attacking the target actor and at the first attack the camera rotates to face the target actor .
I have to things that currently aren’t working smoothly for me:

1. When I hit the target actor the montage that currently playing is overriding the desired rotation and slightly misses and not aiming directly to the character, I want to get the every hit the character will rotate to the target actor exactly and will magnet to it.
2. I want to add another layer on this system that performs a direct attack and rotates the character to the target actor when the movement input “aiming” to the target actor.
   Can some of you please help or direct me to the way I can perform and execute this visions?

[ruby cobalt]

I'm creating an interpolation between two parents.. but I suspect I don't have the correct approach for the rotator..

[abstract oar]

Hey there, I want to ask if there is an node to get all options from an enum as an array.

[ruby cobalt]

the rotation issue in action..

oh I should interp them seperately i guess..

[frosty heron]

Wdym, you want it as string?

like for a combo box?

[distant hollow]

Known or unknown enum?

[frosty heron]

@abstract oar If you want it as an array of strings, you can do this

[abstract oar]

A known

[distant hollow]

It would require an array of booleans as the pass-in argument because you specified so (input)

[solid trout]

of course, but how do i set that up?

[distant hollow]

Then run a loop, Select enum and output to string or something and add them to the array

[solid trout]

for example, CallFunctionByNameWithArguments takes a string-ish thing as an input, so it currently works (with 20 separate booleans) as "ChangeExits true true true false false true" ... etc

[distant hollow]

I mean do you want or not want an array of booleans as an input?

[solid trout]

i do

but how do i convert the concept of an array into a string

[frosty heron]

An array of strings?

[distant hollow]

Oh
