blueprint

[humble wigeon]

Hello, I've been trying to design my ammo system for my tank game, but I'm stuck on how to come up with an implementation that works without having to program hard references into the Player pawn BP, I have a tank the player controls to shoot different types of Ammo, I have explosive rounds and sticky charges so far. in my BP_Tank pawn I perform a line trace after getting input from the player, currently there's a shoot function that checks using a boolean flag if the tank should shoot explosive rounds or sticky charges, this is toggled using another input action but you can see how this can get messy.
The type of ammo changes the recoil of the tank barrel and the fire rate (both of which at the moment are computed and executed inside the Tank Pawn BP).
What's the recommended way to go go about designing this? interfaces? Enums? Strucs? Something else? 🤔

[dry sleet]

I think it's just a common misconception -- on the other hand I don't know for certain either, but signs point towards it just being good ol' nodes! :)

[gentle urchin]

Yepp, surely it does (altho that could have been made on the go just to guide blueprinters. While it still did a native thing )

[golden kite]

Insofar as it is a pure function with no execution, it should be performant. Beyond that I'm not sure how the bytecode is compiled by the BP but it should be more-or-less equivalent. though I have also heard (perhaps here) that it was more perfomant....

[golden kite]

I'm sorry, I lost the thread of the question with all the details about implementation. What exactly is your question about?

[lofty rapids]

for one thing instead of a bunch of booleans maybe an enum for current state so you can add others and maybe do a switch

something like a shooting mode enum

[gentle urchin]

Array*

Less work.

State = index.

[humble wigeon]

I'm trying to understand what's the best way to go about designing an ammo types system, at the moment the pawn tank performs a line trace and spawns a different bullet type depending on a bool the player can change, but I feel like this is bad system design as it can lead to messy spaghetti code and duplicated nodes,

[humble wigeon]

sorry forgot to tag with a reply my previous message 😅

[gentle urchin]

Ammo is a seperate class, so might tank head be?

[dry sleet]

Do you prefer this to be pure Blueprint? :)

[humble wigeon]

right, but what happens if on different parts of the tank graph I have to check what's the active ammo? For instance, different ammo creates different recoil, so now I have two places where I have to check which type is the ammo type, 1 for when I spawn the bullet, and the other when I add recoil to the tank mesh

[dry sleet]

For something like this I would probably make a DataAsset containing the ammo details (such as recoil force).

Then you can have a variable containing such a DataAsset, and when firing, simply query it for the required properties.

[humble wigeon]

datasetAsset you say 🤔

[dry sleet]

[humble wigeon]

Whole project is blueprint based

[dry sleet]

I don't know how good that explanation is (haven't seen it recently), but Mathew's videos are usually good!

DataAssets are very powerful.

You can create them in Blueprint but some things are nicer to do in C++.

[humble wigeon]

I'll look into this, thanks 👍🏻

[dry sleet]

Anytime! Honestly it's a Unreal powerup!

[humble wigeon]

I thought interfaces was going to be it, but then I realized how I don't really have blueprints to implement them with

if that makes any sense..

Got a tricky one for y'all this morning. I have this actor that's meant to attach a physics constraint to any actor that passes through a collider. Simple enough. Except it just doesn't work the FIRST time an actor passes through. Works as expected every time since then.

But here's where it gets weird. If I disconnect the pin to that ProjectPointOnPlane node, it all starts working first time, as expected. And the really weird part is, if I then manually set the plane normal to 1,0,0 then the bug reproduces.

[lusty sphinx]

Is there a simple and cheap way to get the z height pos of the floor an actor is on? For my prototype, I was just manually entering the z height because I wanted to avoid running a line trace every time I wanted to get the floor height or having a scene component at the actor's feet to get floor height.

[dry sleet]

Do you have a Character Movement Component?

[lusty sphinx]

Yes

[dry sleet]

it automatically traces for floor every tick regardless

you can get the latest one, it's just a hit result

called something like Floor... CurrentFloor, something like that

[flat coral]

This made me suspicious that ProjectPointOnPlane was somehow divide-by-zeroing that first time? So I printed out both a working and non-working shot, and it's not.

[lusty sphinx]

tyvm! this is exactly what I was searching for. I figured there had to be something like this built into the character.

[dry sleet]

haha yeah it's nice not to do double work!

[fervent breach]

question - I am working on a spawn system and wanted to know what is better - having all the enemies already spawned but deactivated until the player runs by. Or creating the enemies and later destroying them? My big issue is that I want to customize variables for a good number of my enemies, so like if I have 2 turrets, the range of both of them can be different despite both using the same blueprint. This is fine and easy when I just deactivate them, but I don't know if this might lead to memory leaks or slow down in the future, or if just creating and destroying is a better option?

*and in terms of creating / destroying, I don't know an easy way of having custom changes to variables persist to the newly made enemies

[forest summit]

Hi all, so I have a vector math/rotation question.

I'm working on a Valheim inspired building system and I'm trying to get the building pieces to offset from walls based on the piece's size and rotation. The system I have so far clips into walls and generally doesn't offset correctly at certain rotations but I cannot figure out how to get this to work correctly.
Any help or advice would be appreciated. 😁

Blueprints and video demonstrating the issue:

[queen dagger]

ok

so lets say i have a heavy attack binded to a key, if i want it to also be linked to charge stun attack where if you hold the key down it charges how would i make the same key know which attack to use based on how long you press a key

[lofty rapids]

an integer that represents a count of how long you have held the key down ?

[gentle urchin]

float*

EIS got that tracked already

[queen valley]

is there any better way to use events that need to activate same function but with a different variable, rather than stacking them like this?

[junior prairie]

Definitely create them when you need them, don’t have them all spawn at the beginning. You can set any variable to Instance Editable and Expose on Spawn to set variables programmatically as you spawn an enemy

[lofty rapids]

create a custom event with inputs, and then call that instead

or a function

[queen valley]

i am calling that i first have the on hovered event for button A to call a custom event and then same for button B and C and so on

[gentle urchin]

hard to see exactly what you're doing so hard to advice anything really

[junior prairie]

Yeah image is too blurry

[gentle urchin]

hovered function for a button

gotcha

not much else to do but bind them up

either like that or procedurally

somehow iterate all children in the container, grab all buttons, bind to their hovered etc

usually requires custom button as default ones dont have any decent delegates for this

commonbutton does however

[queen valley]

will just keep it this way then

hopefully this doesn't somehow impact performance

[gentle urchin]

if its only these 6 then yeah for sure

or you know, create your own button base

and edit the settings in the actual button once

instead of having to call this function 🙂

pro-tip of the day

[queen valley]

cant

have to call it cause it has to change on click

hehe

[gentle urchin]

Ofcourse you can

[queen valley]

6 buttons with clicked, hover and unhover events

[gentle urchin]

this could all be handled inside the custom button widget

no problem

no need to 6x anything ^^

[queen valley]

wdym

i cant bind a function directly

without making an event

[gentle urchin]

You'd just setup the event once inside the button

then use the same buitton for all buttons

[queen valley]

how would i know which one is which then

[gentle urchin]

in which context

buttonbase comes with an event dispatcher

if you neede it outside for some reason

[queen valley]

i have to know which button to change the "inventory filter" to

[queen valley]

ah

ok

[queen valley]

does that have any performance benefit besides being clean

[gentle urchin]

no

[queen valley]

cause im not gonna touch it again probably

this*

[gentle urchin]

Makes sense

if it works and aint causing problems, dont touch it : )

[queen valley]

haha, me in 2 years wondering wtf i did here trying to track where everything leads lol

[gentle urchin]

yeah spaghetti dont age well

[queen valley]

thats why imma put it in the freezer and never touch it again

[lofty rapids]

thats a tiny image, can't see anything

[flat coral]

Still trying to figure out the issue where this physics constraint fails to apply but ONLY the first time it's triggered. I'm pretty sure it's something to do with the position it's attached from, but no idea why.

I've got a boolean now that switches the bug on and off. Screenshot shows the position of those two points in space, relative to the collider. Green works every time, red is bugged.

What's interesting is it's not about distance. I can try to go through this thing as far as possible from the green point, but it still works.

[rich ferry]

Odd behavior with component overlap....

I want my bayonet to deal damage when it overlaps the other tank (named Kaiser), but it usually does not trigger an overlap event. That could make sense to me by itself, but more confusingly it often triggers an overlap event when the bayonet is nowhere near the other tank. Am I missing something obvious? Lmk if more info is needed.

[flat coral]

Now it's getting weird. Unless...

It stops working exactly at the colider boundary.

[dawn gazelle]

Tank bayonet?! I LOVE IT XD

[rich ferry]

Lol thanks ❤️

[dawn gazelle]

But to respond to your question, the overlap is triggering based on the collision settings you have set up for the bayonet component. So if it overlaps with say the ground or walls, then an overlap can occur.

[rich ferry]

It's only overlapping with the tank, that part is fine. What confuses me is that the bayonet will be in the middle of nothing, yet will trigger an overlap event when my tank body bumps into the other one.

[lusty sphinx]

I'm trying to figure out why my stop movement event is not working the way I expect. I would think that I should be first calling "Stop Move Forward" and then use a "Move to Location" node and call what I want with "On Move Finished", but if I call it in that order, my enemy char seems to still move forward after it reaches the goal location. Only way I got it to work is if I called "Stop Move Forward" after "On Move Finished"
EDIT: Further testing, for some reason when I call StopMoveForward, it does not seem to clear the timer for move forward for some reason. Gonna keep bashing my head against this issue

Also, is there a way to use the AI "Move to Location or Actor" to make it move to the exact location? I tried messing with the acceptance radius values, but it seems to base that radius with the edges of the characters collision capsule instead of the center position of the character, so I can never get it to move to the exact spot I desire

[steel furnace]

forgot how to set a collision mesh on a dynamic mesh component to be what it was pre-boolean. I was able to do it before but that project corrupted and now I don't remember what I did.

[golden kite]

I have an instance of a blueprint on my stage. BP_Controller. Whenever I edit the blueprint itself, compile and save, the instance in the outliner is renamed with a 1 at the end BP_Controller1. If I rename it to remove the 1 it sticks until the next time I edit that blueprint. What's the deal? It hasn't happened to any of my other blueprints on stage....?

[golden kite]

I'm not a big fan of this self-referencing event loop. That doesn't seem right.

If you want to execute that event once per tick, then just hook it off the tick. There's no need to use a timer on top of that.

Or if it's on an animation BP, you can also use onUpdateAnimation event

[lusty sphinx]

I wanted to avoid having a branch check on my event tick since I am only calling move forward during a short specific section of the fight.

[flat coral]

Okay, so, see the BeginPlay block here? Basically a no-op right, since that same component will be moved again in the OnComponentBeginOverlap code?
Except, that BeginPlay block makes the lower block work. Why? And why does it have to be to the edge of the collider? What is HAPPENING here?

[proud notch]

Hello,

I have a BP that creates a few components, this components have a BP of a car.

is it possible to "extract" the BP of the car from the parent BP as an actor in the scene?

[faint pasture]

What are you actually trying to do?

what effect in the game world

[flat coral]

Replicating the feeling of a fly flying into a spiderweb.

On overlap I move the AttachTarget to the closest location on the web to the pawn, then apply a constraint between it and the pawn.

[lusty sphinx]

I think I managed to get it to work. This is the solution I came up with for my problem if anybody was interested.

[faint pasture]

So what doesn't work about the overlap code if you lose the BeginPlay?

what is attach target area? A scenecomponent or primitive or what

I'm guessing you got some self-overlap stuff going on

[flat coral]

If I lose the beginplay, then this fails to capture the pawn the FIRST time it goes through. It'll work reliably the second time.

[faint pasture]

print overlapped actor and component

you really oughta be using a physics handle though

[flat coral]

First I"ve heard of this physics handle?

[faint pasture]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Physics/Components/PhysicsHandle/

[flat coral]

you're fucking right about the self overlap!

Working version:

LogBlueprintUserMessages: [BP_NetBase_C_1] OverlappedComponent=BP_NetBase.CaptureArea OtherActor=BPI_BaseShip_C_0 OtherComp=BPI_BaseShip_C_0.BaseCollider

Bugged version:

LogBlueprintUserMessages: [BP_NetBase_C_1] OverlappedComponent=BP_NetBase.CaptureArea OtherActor=BPI_BaseShip_C_0 OtherComp=BPI_BaseShip_C_0.BaseCollider
LogBlueprintUserMessages: [BP_NetBase_C_1] OverlappedComponent=BP_NetBase.CaptureArea OtherActor=BP_NetBase OtherComp=BP_NetBase.AttachTargetArea

This ALSO explains why none of my breakpoint debugging found the problem. The bugged version IS setting it up correctly, but then immediately ruining itself.

Fixed it. As simple as turning off overlap events in the attach target.

I'll give some thought to physics handle. This is feeling pretty good right now and I like how configurable the physics constraint is, the handle doesn't seem to offer as many options.

[forest summit]

If anyone knows about vector math or rotating vectors any help would be appreciated
#blueprint message

There might also be a simpler way of doing this so any suggestions are appreciated

[limber parcel]

you will need to change the pivot of your construction meshes accordingly, then its easy to rotate and place them

[faint pasture]

I think the handle is just a wrapper on constraint

with an interface like SetTargetLocation etc

[flat coral]

The thing is I'm not actually using the main "linear limits" part of the constraint, I'm getting a better feel with "linear motor" and I don't see those options here.

[faint pasture]

yeah i'm not sure which one they use

if constraint works use it

but I think you can go without the 2nd component

just constrain pawn to nothingness

[forest summit]

If I'm understanding you correctly, I am already doing this with snapping building pieces to each other, moving the mesh in local space to change the pivot point relative to the blueprint, but I'm not exactly sure how this would help with this current issue. I'll give it a try though and see if this changes anything.

[faint pasture]

Do you want it to offset at predetermined distances or just where the colliders touch?

do you have a strict grid or is it freeform

[pine mesa]

How do I make an object move by holding a key?

[limber parcel]

by creating an input action and setting the objects position when its triggered

[faint pasture]

However you want

Start with printing something when you press the key

[forest summit]

It's freeform, and just where the colliders touch, I'm doing a trace specifically to get the location and hit normal

[faint pasture]

How is the placed object oriented?

90 degree rotations from the hit normal?

A quick and dirty way would be to move the object to some offset then move it to the hit location with sweep turned on

but I would really suggest some sort of grid system if you want your constructions to not look like bird nests

[forest summit]

Well I'm trying to recreate the Valheim building system, which I would call "freeform" but maybe I'm misunderstanding you.
Here's how it works so far...
https://youtu.be/It8qxZKFayE?si=fPf_S7dLhbxS5njs

[limber parcel]

valheim uses snapping points...

[forest summit]

yes, so does my system, but it's not "on a grid" therefore I said freeform 😅

[faint pasture]

if you're snapping you're on a grid, just the grid can be dynamic

grid =/= aligned with the world's grid

it jsut means consistent with connected objects

[forest summit]

ok, just a misunderstanding then

[pine mesa]

I have this right now, but you have to press multiple times for the input to work.

[limber parcel]

well then set your input action correctly

u can make it fire repeatedly

[forest summit]

I feel like there has to be a math solution that will work dynamically as I add objects, I feel like I'm close to a solution but I've just hit a wall.
I'll just have to try something different and hope it clicks.

[limber parcel]

i think you should watch some tutorials on construction systems

[trim matrix]

wouldn't it work with collisions?

[pine mesa]

How do you do that? I’m a beginner.

[limber parcel]

i suggest reading the documentation about input actions

[trim matrix]

what would you do for that kind of building system?

would you use collisions? or a grid or idk

[forest summit]

I had looked for tutorials prior to starting the project but they were all very basic and not really what I had in mind

[faint pasture]

Collisions snapped to grid

Line trace -> get point -> snap it to ThingTheLineTraceHit.GridReferenceFrame

that's how Space Engineers etc do it

[trim matrix]

Ohh, because I used another way for my system, I don't know if that's correct:

There's no grid, you are free to build wherever you want, just the first one must touch the ground, I used collision on all builds, then the others build around can snap correctly together with collisions...

@faint pasture

[lofty rapids]

probably a timer on press, clear and invalidate on release

[forest summit]

I think as SourceControl suggested the new Enhanced Input Actions system effectively does this by default

[lofty rapids]

right it's built in

[forest summit]

I only learned to use it recently but it's really useful and easy to set up

[lofty rapids]

enhanced input is much more difficult to use than the old way

[trim matrix]

you changed it lol

[lofty rapids]

lol i realized pretty quickly

[forest summit]

It require a small amount of set up but once that's done I think it's relatively easy to use

[round spruce]

Git or perforce for version control ?

[limber parcel]

git

[pine mesa]

If I use the enhanced input system wouldn’t that limit me to using only one character? I want to be able to control 2 characters using different keys like WASD for character 1 and Arrow keys for character 2. So, how would I go about making the inputs work for both characters?

[forest summit]

Git is way easier to use imo, specifically Github Desktop

[limber parcel]

by making separate input actions for each character

[pine mesa]

After I make the separate input actions for each, how do I implement them? Because the only way I’ve learned so far was to change the game mode of the level and set the pawn as a single character.

[limber parcel]

try watching some tutorials

[trim matrix]

literally like you'd do normally

[pine mesa]

I have been for the past 4 hours but I’m still stuck, which is why I came here. 😭

[limber parcel]

if you were watching a tutorial you would know how to add an input action

[pine mesa]

What is normally? 😅

The game mode pawn only lets you select one actor, as far as I know. So I’m quite confused.

[pine mesa]

No no I know how to add it, my problem is implementing it with 2 characters and not one. The tutorials only show how to do it with one character.

[limber parcel]

you can set an actor to receive input from player

[trim matrix]

but you can add as many input actions/ mapping context as you want

on 1 pawn

[forest summit]

I think they're talking about having multiple pawns in a local multiplayer game

[trim matrix]

"the tutorials shows"........

Really could use some help with a trace.
I am tracing to the ground on my vehicle from a socket on the skeletal mesh down to the ground, I need the trace to always be in that direction, I mean when the vehicle is flipped over I need those traces to be pointing to the sky, meaning I need the trace to al ways go in the direction of where the ground is expected to be in contact with the wheel. You can see in the photos the socket, the trace setup, the correct results when not flipped over, then the incorrect result when flipped over. I would really appreciate helping me understand how I can achieve this.

[limber parcel]

guess ur socket is not rotating with the car?

[faint pasture]

yeah why would your soekct not rotate with the wheels?

er with the chassis

or suspension

print socket.Up and see if it ever changes

[trim matrix]

Maybe because even though X is pointing down, I am still getting up vector in the trace setup, so thats always up in world space ... IDK

[faint pasture]

print socket.up on tick while flipping over

[trim matrix]

Not sure, socket is parented to wheel bone

[forest summit]

I hate to say it but I think you just need to look for tutorials on local multiplayer, hopefully that should give you the info you need to combine that with the Enhanced Input system

[trim matrix]

Will do and reply

[pine mesa]

I may have found a possible solution… I’m gonna try it and also look up more tutorials to watch hehe https://forums.unrealengine.com/t/how-can-i-control-2-pawns-with-1-controller/291756

Hello!

Does anyone know why when simulating/recording with the take recorder physics are working ok but as soon as I render the physics on the output video are messed up?

This is a video with the steps I follow and the final resut: https://youtu.be/wslYK55Ilq8
Happy to provide more details if needed 🙂

[trim matrix]

Flipped over

[trim matrix]

At begin play (not flipped over)

[limber parcel]

your vector math is wrong

[wise ravine]

Hey, dumb question. What does ' Other Actor ' and 'Other Component' mean exactly?

[dawn gazelle]

Seems odd to be adding the up vector to the location of the socket, and then subtracting the wheel radius.
You probably want the up vector inverted and then multiplied by the wheel radius, and adding the socket location.

[forest summit]

They are the actor that overlapped with the hitbox and the component within that actor, usually a mesh or other collider

[wise ravine]

So it's the ' Other Overlapped Actor ' ?

[forest summit]

yes

[wise ravine]

Interesting, okay ty

[forest summit]

np, you can also check them using a print string

[wise ravine]

So why do we use Other Actor when casting instead of Overlapped COmponent?

Because what were casting to isn't a component?

[forest summit]

I think overlapped component will be the hitbox itself?

[trim matrix]

Correct. Your character is an actor and it does have components. A component could also be something like a skeletal mesh or static mesh.

[forest summit]

or did you mean other component?

[hidden cedar]

Is there anyway I can attach a target point to a moving object so that my enemies can spawn on moving platforms?

[forest summit]

Are you just trying to use the target points to get the spawn location?

[hidden cedar]

yes

I have a wave spawn system and it spawns enemies on target points

[lunar sleet]

Attach actor to actor

[hidden cedar]

Dang didnt know that was a thing. Thanks!

[limber parcel]

or make a spawn component

[forest summit]

That is definitely one solution, components are also very useful if you've never used them before, definitely worth learning about

[leaden helm]

Quick Q: Have a map gen, it creates and stores a lot of data, makes a lot of ISMs. When I open level to the same level, it seems to make a new map as expected. Its clearing all that data and ISMs and GC'ing any memory and such right?

[faint pasture]

the cool thing about having spawn actors is you can just get actors of class

you can't just get all components of class in the world I don't think

[hollow tendon]

Hi, what is going on here?

if it is from -0.4 to 1 it wont work
if it is from 1 to -0.4 it works

this make no sense what so ever

Note that -0.4 means visible, 1 means invisible

I get scalar parameter value then print string it, it shows the numbers are indeed being updated

is it a bug in the engine?

[plain jay]

has anyone seen this crash before? it only happens when i try opening a map by double clicking it. doesnt matter what map. but I can load into these maps just fine in game, I checked the log and its equally enigmatic.

Ive tried opening a blank map and it does the same thing, the only thing the engine will open is the map it loads into.

ive tried verifying the engine files, deleting saved and intermediate, but no luck. kind of at a loss here because it started happening out of the blue

looks to be something to do with the content browser but I have no idea what I could do to fix that lol

this is in 5.3.2 btw

heres the log as well

[tulip anvil]

have you attempted to verify engine files?

[plain jay]

I have yes, everything validated successfully, but just to be sure you mean in the launcher under the engine select verify?

if there is another way I am unaware

[tulip anvil]

correct,

[plain jay]

I can simply create a new level in the content browser, save it, and then open it by double clicking and I get that crash. doesnt seem to matter what map it is 🫠

[tulip anvil]

what if you try to open it from here?

i imagine the same thing but just for the sake of it

[plain jay]

yea same thing just tried. lol

like the odd thing

is that when my default level opens up which is a forest, I can open my developer menu while playing in editor and then load into any of those maps, just not through the content browser

[tulip anvil]

very odd indeed. it seems like an engine bug but not one i've seen before in 5.3 and verifying the engine should usually fix like random corruptions or some such.

have you tried in a brand new project?

[plain jay]

let me try! if it breaks there I suppose I can just assume its an engine bug, uninstall and reinstall and see if that helps

[tulip anvil]

if it happens in a brand new project with a verified engine it could also be a driver or windows issue of some sorts

i know one of the most recent nvidia drivers has some performance issues

[plain jay]

hmm new project seems fine

[plain jay]

ok so interesting, I backed up my config folder, deleted it, and then re-opened the project and now I can open those levels. something must have gotten borked lol

[tulip anvil]

good to know

[swift bough]

Is it typically best practice in a game with multiple controlled pawns to put Input Actions shared by all pawns into somewhere more global like a Game Mode base? It feels strange having my "inventory open and close" input actions duplicated in both my player character and the boat pawn you can also control.

[plain jay]

further inspection comes back to nanite being enabled if you are curious

[faint pasture]

not gamemode for sure

put them in PlayerController if you want to

[hollow tendon]

Hi

[faint pasture]

it can go like:
Input -> get MyPawn -> get InventoryComponent -> show it

[swift bough]

Ahhh yeah that's smart

[faint pasture]

I typically put common inputs in PlayerController and specific ones in Pawns

if you were making GTA you'd put walking etc in the pawns but you'd put pause and ShowMap in the playercontroller

[swift bough]

I'm going to migrate the common controls now, thank you!

[proud salmon]

add a spline component to the actor.

[lunar sleet]

You attach actors to it

Hi I was having an issue with code similar to the one below, where the door was only rotating once, and then snapping when I interacted with it after. By using Print Strings, I saw that during the first execution it was outputting multiple repetitive executions after the timeline, however after the first execution if you interacted with the door, there was only one singular execution after the timeline node. Does anyone know what the issue could be. (This is not my exact code, but basically the same nodes)

[faint pasture]

why are you adding

no

set

[faint pasture]

A timeline is basically a temporary tick

with animation tracks

you want the door to be in a different position every frame as it's rotating. Thats the update path

A simple door might be like:
Event -> branch on isOpen -> Play -> Update -> set angle

ahh okay thanks im gonna go try it out ❤️

[rugged atlas]

Hello, my name is Raj Oswal. From San Diego, California.

I am looking for a solid freelance unreal developer that has experience with building games for Meta Quest devices. I have launched a children’s immersive educational program and working with three international schools in Shenzhen China. For that program, I have built an astronomy app on unreal engine for MetaQuest devices. Unfortunately ,the developer I was working with is no longer available so I’m looking for somebody to take over.

Ideally somebody’s with 4-5 years experience with particles effect’s, some animations and mainly blueprints.

This is a part-time contract opportunity.

If anybody is interested, please contact me in a private message and I will share more about our app and we can discuss more..

Here is a TEDTalk I gave on, the power of immersive education : https://youtu.be/uRMjJhPUPCM?si=j0g4nlq5ahDPIs5l

#freelance-jobs

[urban moon]

Could anyone tell me what I should be looking at to fix this? I never touched or changed anything in this blueprint for that interface and all of a sudden its claiming it as an issue

The parent is not touching or doing with it either

[dull shell]

Compile parent class

[urban moon]

Parent combiles fine. Maybe I need to reparent? Maybe something is stuck

oh, its an issue with the interface I think. I just realized the one its calling out is different than the interaction one

Looks like I made a duplicate Function on two interfaces name wise. Time to see what all that messed up for me in the other work I was doing earlier 😄

[dull shell]

Your interface functions have duplicate names

[urban moon]

yup, just noticed that as well. Now to figure out WHY I did this and what other errors are in the other things I was working in cuz of that

[sterile spindle]

hiya, relatively new UE5 user. I've been using the Actor Forward Vector to create a line trace, but I'd like to angle it up by 30 degrees. I can sort of do it, but I assume it's only angling it by world rotation, because when I face forward in the world it works fine, but when I face the opposite direction it's angling down. How do I rotate the forward vector up by 30 degrees regardless of the direction the actor is facing?

[trim matrix]

can you show the code you are using

it's probably an error in it

[sterile spindle]

Offset is (0, 0, 0) so it's just in the center of my actor and rotation is set to (0, 30, 0)

[marble tusk]

Probably Rotate Vector Around Axis. Something like this

[trim matrix]

yea maybe, I dont know much about Rotate Vector node.. sry

[marble tusk]

so then the whole thing could be like this

[chrome pumice]

Guys quick question, should i build maps on unreal or on blender? i feel like when i build them with cubes on unreal its much easier to handle the collision or what do yall think?

Ive built some rooms now with blender today but it feels like the collision is insanely terrible every time

[trim matrix]

depends

[chrome pumice]

Specially with round objects

[trim matrix]

then create custom collisions

[chrome pumice]

yea but like

on whole maps with details

[trim matrix]

it works as well

[chrome pumice]

isnt it better to do in unreal?

[trim matrix]

if your map is a cube (probably not) then you can use ue

but blender for better shapes or any other 3d apps

[chrome pumice]

For example i want floating rooms in my level that randomly spawn, should i set them up in blender?

[chrome pumice]

I mean i dont need allot of complicated shapes

im gonna keep trying arround, still thanks !

[trim matrix]

1 for collision
1 for the mesh

[sterile spindle]

works like a charm, ty 🩷

[faint pasture]

The level itself should be made in Unreal

you'd use blender to make your meshes etc

[chrome pumice]

yea but the whole room, should i do it in blender or in unreal?

either a whole room in blender or i line up 4 walls and make the room in ue5

[dawn gazelle]

You'd make the things that make up your rooms in blender. You'd place your pieces in Unreal.

[chrome pumice]

OKayy thanks 🙂

[dawn gazelle]

An example: You wouldn't want to import a mesh that has 1000000000 vertices and much of that geometry is reusable or could be made modular as Unreal could instead "instance" a lot of the meshes if they were in pieces rather than 1 gigantic mesh file.

[deep void]

yo gang, I need some camera help in my pawn BP.

I have a pawn BP with a camera attached to a train, that moves on a seperate circular spline.
I want the player to be able to move the camera around (look around) when I possess this camera, so I have enabled 'Use pawn Control Rotation'
But in doing so, now the camera doesn't rotate with the train. (if train turns 90 degrees right, the camera stays at 0 degrees ahead in world space)

How do I have it so the camera turns with the train but the player can also look around?

[faint pasture]

Instead of use pawn control rotation, you can:
Tick -> get control rotation -> set camera RELATIVE rotation

[deep void]

works perfectly, thank you for your time 🙂

[vestal acorn]

Trying to change the value of a ,,date time,, variable. For testing I just want to set the hour to 2, but it keeps printing 0 ( for both approaches )

What am I missing here :/

[dawn gazelle]

Probably can't represent year 0, month 0 and day 0.

You may want to use a "Timespan" instead?

[vestal acorn]

That did the trick, thank you ^^

[dawn gazelle]

Either that or take a "Now" and add 2 hours to it.

[crystal flax]

hello there does anyone know how can i make gap/hole in wall in real time in game like i want that my walls each time they appear they should have diffrent type of gap/hole in ther so that my player can adjust accordingly and can go further

[frosty heron]

Start looking at what unreal can offer for what you need

Eg fracture system

[forest summit]

It depends how complex you want to go, you could just do something as simple as using cubes in a grid and removing them where you want the hole to be, or use a masking material to visually put a hole in the wall and use blocking volumes around it for the collisions.

[crystal flax]

yes i want cubes in a grid that remove from specific place each time the wall spawn

[crystal flax]

is there any specific documentation or video which can tell me about this by the way thanks i never heard this before i will check it

[frosty heron]

There are videos, im not sure about documentation.
Give searching a go

[crystal flax]

yeah

[crystal flax]

but i think this is mainly for destruction but i want to remove specific part like each wall come with specific shape drawn and the area which space is drawn it is empty and the next wall automaticly come with diffrent shape and my player have just to move it from that space i just want this type of system basically

[frosty heron]

I can't visually picture that

You can always get crafty with animating your own wall and cut parts of it

Using 3d modelling tool

[crystal flax]

yes i am keeping it as a last option

if nothing works i will do this way

[frosty heron]

A bool operator will do the trick

[crystal flax]

i see on video but it is using unreal engien 5 and in my laptop unreal engine 5 does not work

[frosty heron]

At least that's what it's called in 3d max

Doesn't matter what ue version, just do it in 3d modelling program. I was talking about fracture anyway which isn't what you want

You want a hole with specific shape, then you have to do the manual work. There is no such system

[crystal flax]

no there is some blueprint class called dynamic mesh that is not there in ue4

[crystal flax]

random generated hole i want

in a wall in a shape of cubes

[frosty heron]

There is a type of mesh that can be sliced

[forest summit]

I think you're overcomplicating it 😅

[frosty heron]

I prefer the simplest way. Make some holes in 3d Max, have a set of them. Then import all of them and just get a random one from what you export

[forest summit]

You can just make a wall out of cubes in a blueprint and set up different states where certain cubes are removed, or you could use some sort of collision or trace to get certain components (cubes) from the BP. That's how I'd do it anyway.

[frosty heron]

Using blocking volume suggest that it's not randomised at run time but placed in editor time manually

[crystal flax]

ist there any way liek i make a wall using cube then in construction script some cube randomly dissaper based ona logic and create some holes so that my player can pass

[frosty heron]

You can , just translate what you want to logic and operator

And implement it

Randomly dissapear doesn't scream making shapes tho

Also I don't get why u want to use cubes. What kind of shapes and how many cubes do u need to represent a round hole?

Imo just cut out some set of walls, randomise it in bp. Call it a day

[crystal flax]

ohhh instaed of dissaper can i sue spawn actor from class and place 9 arrow and randomly cube will spawn on those arrow not all arrow and in which cube is not spawn i have to pass through that

i didnt say i need a round hole i just need a hole it can be of any shape

[frosty heron]

My statement is still valid. You said any shape but what about round shape? How many cubes do u need to represent that hole and how many you have to delete and what algorithm do you need to create the round shape?

I can only suggest simpler approach, wish you the best on exploring alternate way tho

Just don't see how it can be done with cubes

[crystal flax]

ohh i guess i am unable to explain you let me share the video of which type og thing i want to create than you understand why i am going with cubes

https://www.youtube.com/watch?v=IaczoAB66KU&t=4s

i just need to make somethign like this

[frosty heron]

Would been easier if u said something like Lego to begin with

That's not really any shape

In that case just use grids to represent the boxes

[crystal flax]

ohh sorry i think it was

[frosty heron]

And just remove the one you don't want

[crystal flax]

okay but can you tell me how can i remove is there any function which cna help me

[frosty heron]

You can do that in bp easily

Represent the walls as grids

Make some function that define the shape

Do a series of those functions as needed

And just pick one at random when you want to spawn the wall

Spawn wall-> cutMyWall

Cut Myall just pick the shape randomly

[crystal flax]

okay i think i am getting it let me try this once

[lost canyon]

Hey All! I'm teaching myself blueprints, im trying to use a branch node or something on event begin play so I can have it do multiple things, for some reason the branch doesn't work, and there's no else if or anything, I remember using one once but I can't remember what it's called, could anyone tell me please?

[forest summit]

Kind of depends on what you're trying to do, the most basic answer is a sequence

[lost canyon]

That's the one! 🙂

I am just adding a UI to my Character Blueprint and can't use 2 event begin plays, but I can use sequence so it adds the input mapping THEN adds the uI ❤️ 🙂

thanks

Quick question whilst I have someones attention 😄 if I want to tab into the inventory menu etc, would I:

use an action map to remove in-game widget and create tab menu, then once I finish in the tab menu flip flop, would be, add the in-game menu and remove the tab menu?

would that be how everyone does it?

[forest summit]

If you're moving through multiple menus you could use a Widget Switcher, then you only need to load one widget

[lost canyon]

I'm still learning the widget switcher thing for the canvas right?

I will use the Tab Menu where I can use canvas switchers between them but one is for the in-game UI and the other is for the menu system?

or is it all one?

[forest summit]

Yeah I would probably have a separate widget for the HUD and then just hide it while the menu is open and then unhide once the menu is removed.
I'm far from an expert on UI though, I'd suggest maybe watching one of Ryan Laley's many videos on UI/Widgets, that's where I learned most things

[lost canyon]

awesome will try that thanks dude !: )

🙂

[dark drum]

I use common UI stacks. Pushing a new widget to the stack hides the old one. When the new one is deactivated, it shows the widget below it.

[forest summit]

ah yeah, I only heard about Common UI recently but still haven't looked at it

[remote meteor]

Why common UI force enter key to be not handled as a accept button reeeeeeeeee

[dark drum]

I'm pretty sure you have to setup accept and back handlers lol. (Not that I know how)

[remote meteor]

They utilize commonanalogcursor to morph all gamepad accept clicks to mouse left click, but they dint do for keyboard, so you can never use Enter key for accept, because in SCommonButton, its if key = enter, return unhandled

[dark drum]

Fair enough. Good to keep in mind.

[gentle urchin]

Ouch

But cant you simply override this?

[final quest]

i'm geting None from get copy.

here is variant manager set

[versed sun]

Try Event Construct > Delay Until Next Tick> Get Actors

Widget might load before variants spawn

[final quest]

here msg

it on even construct

here string value's

[forest summit]

Did you try this?
#blueprint message

[final quest]

you chech here i have use it

[final quest]

ok

before get all actor or after ?

[versed sun]

before

[final quest]

not working

even unable reference for this like actor in UI

[wise ravine]

Ahh, alright thanks mate that explains it.

[forest summit]

You're doing this on construct so is the actor even loaded? is there a reason you're not doing this on begin play?

[final quest]

i'm doing it in Widget BP

[forest summit]

ah I see

[wise ravine]

So why does Setting work but not Adding?

[tepid raft]

im doing this tutorial and its asking for a float - float and i cant find it?

[wise ravine]

A float variable?

[tepid raft]

he just says float - float

[forest summit]

just type the - symbol in the search bar and it should show up

[tepid raft]

it dosent for some reason

[forest summit]

are you dragging off of an int or something?

[tepid raft]

im tryna make a gun shoot and dmg enemy

[versed sun]

there is a newer system defaults to Wildcard, just plug a float in

[wise ravine]

Btw that isn't my code, I found it on Unreal forums to use as an example. This is my actual code

[forest summit]

I just loaded up unreal to check haha, forgot about this

[tepid raft]

trying it thanks

the hp wont change idk if ive done smth wrong

[versed sun]

did you add Enemy Tag ?

[tepid raft]

yes

i be confused

[versed sun]

put a Print after Event Any Damage to see if it is firing

you might not have collisions set

[tepid raft]

ok

so like

im still new how do i check if collions are set

i fixed it

ive been on this for 12h im a happy bean

[tepid raft]

im unsure what to add to stop this error

[trim matrix]

there's no input to the cast node

you have to Get Player Character first

[tepid raft]

is their a way that would let me end game after players health reaches 0

[surreal peak]

Has anyone had issues with this node disappearing on engine restart in 5.3?

Is there some LoadingPhase wrong on the plugin that contains this?

[limber parcel]

wtf is this node even?

[silk badger]

what is your logic for end game?

[lofty rapids]

tbh i just check on tick if the health is <= 0, then if so i switch dead boolean and run death

but depending on your game there is probably a better way

[surreal peak]

Just grabs the inner Struct from the InstanceStruct that is passed in.

[tepid raft]

Funny u should ask that idk

[limber parcel]

but how does it validate the struct?

[lofty rapids]

the thing just disappears your wires are disconnected and it's just gone ? every time you restart ?

i would take a guess it's the plugin something wrong with it ?

have any other nodes mysteriously disappeared ?

[surreal peak]

Yop

Usually a sign that it loads the in the wrong order

[surreal peak]

By checking the Struct Class

[limber parcel]

cool didnt know that was a thing in bp

[surreal peak]

Yeah we use it a lot when we want to have one function but pass in different data.
The receiver and sender have to agree on the struct of course, but at least one doesn't need to write one function per data

[languid hemlock]

I am working on Utility Widgets. I wonder that do i need to "unload" or do something after loading an asset and done with it? Will it occupy memory?

[spark steppe]

if nothing uses it unreal will unload it for you

which in the editor however might behave a bit different than in a packaged project (the editor likes to keep things in memory)

[languid hemlock]

Since its an utility widget, i'll use it only on editor

[lethal pollen]

Hi! Is there a way to draw an ellipse without using Debug lines? I have found something called Blueprint Spline, but I don't know if I use it would be good for the performance. I looking for something like this:

[tight pollen]

someone can help?

rather, I need something like this to set transform the World Location of actor 2 to the relative position in actor 1

[versed hornet]

like a minimap?

i mean what you are literally asking for is just to take relative position of actor 2 and input it as world position for actor 1

that can be done quite easily

but im not sure it would do much

[tight pollen]

I just need to transform world location to local location but in actor number 1

[versed hornet]

what are you trying to accomplish?

[versed hornet]

so get the relative position of actor 2 compared to actor 1?

[tight pollen]

@versed hornet

this is literally what I need

[surreal peak]

@tight pollen Take the WorldLocation you want Point to be at. Subtract the WorldLocation of Actor1 from it. That's the value you want for the Point then.

[tight pollen]

it doesn't work well

it must also take into account the rotation of the capsule to which it is attached

[surreal peak]

Then rotate the result by the Actor 1 Rotation afterwards fwiw

[undone bluff]

splines are not particularly expensive, the main concern afaik is spline meshes. debug lines are editor only, but UMG comes with functionality to draw lines

really though I'd definitely use splines, they should be easiest to work with and I cannot imagine them being a serious performance impact when used to depict orbits

[remote meteor]

hm, mine stays when restart, 5.3.2 too

tested on a level blueprint tho

[surreal peak]

Yeah it's loading too early. The Object is in a DataAsset which is loaded in DeveloperSettings

That'S probably too early

Will see if I can delay that

[remote meteor]

gotta go fast ♿

[gritty wraith]

Please help, i have a Grid actor and a GridCell actor. GridCells are constructed in Grid. I want to get their parent (Grid), but the cast fails. Why?

[lunar sleet]

Why are you casting self->parent and where is this parent being set

[lofty rapids]

can't you still get units from the child ? or you control it in the parent ? i thought it's inherited

[lunar sleet]

Yeah, I mean if the parent has it, the child has it

[lofty rapids]

what do you need the parent for ?

i can't imagine changing things on the parent or using that data

i just use the inherited stuff on the child

[lunar sleet]

Eh most of that code doesn’t make sense 😀

[short ivy]

what are interchange base nodes

can't almost find anything about them

Trying to get the unique ID of an asset

[lunar sleet]

So I recently had to Google Interchange because it was listed under someone’s plugins as part of the crash log and Google said it’s UE’s import/export framework

[short ivy]

interesting, any idea how to utilize it in blueprints? Casting would need an object input

[lethal pollen]

Thank you. I need to draw a ellipse. I think it shouldn't be too difficult to draw an ellipse with a spline, isn't it?

[short wigeon]

Hi! Im looking to create a doted line between two points on a 3d interactive map. I've done a lot of digging but not sure which is the best way to go about this. Any ideas what method I should be using to create this line? I already have the two points and their world locations. I just need a good method to render a line in game to showcase the distance.

[lunar sleet]

No idea sry. You could drag from the target and see if anything sticks out but 🤷‍♂️

[plain jay]

im not actually sure about that node, but try looking into GUID. that will give you a unique ID from each asset

[flat coral]

Someone will probably tell me I'm an idiot, but I use GetObjectName to get an ID by which to save an actor's data, and I have NOT had any issues with collisions even on fairly complex levels with many spawned actors and actors of the same type.

[short ivy]

I guess via c++ because I couldn'T find a node for this in bp

[short ivy]

but the "getobjectname" gives you the assets name and not an ID, doesn't it?

for example if the actor is a static mesh called blueChair, the return value of this node would be blueChair, right?

[gentle urchin]

Runtime unique name tho

[flat coral]

Yes, but crucially, if the level had a second blueChair, that would be blueChair1

[gentle urchin]

BlueChair_0

[flat coral]

^ or that yeah

It's returning the level's name for an asset, which I think is necessarily unique.

Plus, in my case the fact that it's usually human-readable is a bonus, in case I ever need to manually debug save data

[plain jay]

oh its a blueprint thing, there should be a node called Generate new GUID and then you can simply create a variable from it, or you can straight up create a GUID variable in your blueprint

[short ivy]

First a bit of context, I am trying to replicate a pak mounted chair which was mounted by server and client. It is the same pak file so if references were built upon asset names, then it would have worked but apparently each asset has a serialization ID and a GUID? Now when mounting the pak on server and client the assets apparently have different IDs and thus the engine doesn't know that these are actually the same assets. Right now, the chair does get spawned on the server but is NOT visible to the client. The client does recognize that there was a blueprint spawned and sees it's other functionalities but the assets inside the pak which were mounted like the static mesh, textures etc are invisible to him although he mounted it as well.

[short ivy]

yea but that's a new GUID, not the one of a specific asset

I need to get and assign guids of specific assets

[plain jay]

thats why you promote it to a variable 😉

[flat coral]

Ah yeah, I'm offline-only so that sort of replication problem isn't something I can comment on

[plain jay]

or just make a variable of a GUID

[short ivy]

it would be a variable then of a newly created GUID. Not containing the GUID of the asset and also not referencing that asset at all. Just a random own GUID

[short ivy]

even outside of multiplayer unreal handles it the same way. It's just not as needed to know or implement functions on an ID base then

[plain jay]

I guess theres no perfect way to do that unless you create a custom system with GUID or any unique identifier. I dont think theres any out of the box way to do this, I use it for save games and populating containers and inventories. but maybe im just misunderstanding what you want to do lol

[short ivy]

Even for when saving a game. How do you assign that newly created GUID to the game instance you want to save?

do you make it a map? with guid string as the key and the instance as the value?

[plain jay]

so you can generate a new GUID by hand, OR whenever the item is spawned into the world you can generate a new GUID. Personally I simply expose the GUID variable on spawn and then generate a new one and make sure to use a master actor class that allows me to do all this on its own as long as it inherits the master class.

I use a struct to store my save data, its all arbitrary as to allow saving of any variable or object, and I just create an array of this struct. I get all of the information from the actor using an interface when the game is saved. but it gets a little more complex than that.

[short ivy]

where can you see this generate guid window

[plain jay]

so to answer this question Im using the struct above, saving its actor class, its unique identifier, and all of its variables into the struct

[plain jay]

you have to select your GUID variable that you create in your BP and it should be in your details panel

[short ivy]

Ah yea now I see it

yea honestly I don't think a GUID is what I need

shouldn't all players have the same guids for all actors in the level anyways

I thought the GUID was a unique ID for an asset as in a static mesh or so. For example this static mesh asset called blueChair has the ID "xxxxxxxxxxx..."

not an instance in a level

[plain jay]

GUID is for anything you need to identify, its globally unique so there can never be one like it. unless you create a GUID and never generate a new one and duplicated it everywhere. it just has some extra setup but its a pretty awesome tool

what are you trying to do exactly?

[flat coral]

So, to simulate a spider web that can catch pawns, I've got this pretty simple code. Attaches a physics constraint to an actor as it passes through a collider.
Problem is, I realized last night that I don't need to capture 1 actor, I need to capture N actors. What's the cleanest way to duplicate a physics constraint with a LOT of custom configuration?

[short ivy]

#blueprint message

[gentle urchin]

Wouldnt you just apply a slow effect on them ?

[flat coral]

Nah, goal is for them to get fully trapped and not be able to escape easily. You can only get out the way you came too.

[gentle urchin]

Is there a particular reason you wanna do physics on them ?

[flat coral]

Well, two reasons. First, most of the actors that can get caught in this are just loose static mesh objects. If a barrel flies into the web it needs to stick.

But second, the player pawn moves with physics

[gentle urchin]

Gotcha

[versed hornet]

How would one go about making a fog of war system for an rts or moba?
I think i can figure out how to do the logic for vision, just draw line traces to actors in vision range and figure out if something is blocking, but no idea how to do actual clearing of the fog dynamically to objects.
All tutorials i can find are on simple drawing a circle around a character, but i want it to dynamically respond to obstacles in the game.

https://www.youtube.com/watch?v=u-0vdEt4XvM&ab_channel=Allshar
something a little like this

i guess something with a sphere trace on the visiblity channel?

[flat coral]

Oh whoa so THIS is interesting, the AddPhysicsConstraintComponent node exposes ALL the same options as you get when clicking on a regular component?

[queen dagger]

so i have a health and damage system already

but at the moment its a simplet health pool that gets detucted from when hit, i want to transition to a hit percent where everytime you get hit you increase percent like smash

how would i approach doing that

[swift bough]

It seems that the "GetPlayerCharacter" function returns nothing for me after possessing a new pawn (in my case a sailboat). Is that expected if you're using possess / unpossess to switch pawns? I'm switching between the main character and a sailboat, but I'd like to be able to get the player character while possessing the sailboat. Maybe I'm switching pawns in a janky way.

[gentle urchin]

Dont they all do that 😅

[flat coral]

o god. Do they?!

You would not believe the bullshit I've done

[undone bluff]

you'd just predict the trajectory of the orbit using whatever means you do to achieve the movement to begin with and then draw a spline along those points

[eager thicket]

Is there any way to get it to apply to the whole spline?

[lethal pollen]

Thanks.

[queen dagger]

I want to stand from a knockdown based on input IE player gets hit, enters knockdown and then waits for player input to stand up, what node allows me to identify if a certain key is pressed to notify the stand up

[lunar sleet]

I mean is key down works but why not just do it on the actual enhanced input node

[queen dagger]

you can do that on an input node itself? i didnt know that

[lunar sleet]

Do what, call functions?

[lofty rapids]

it looks like your setting to the original mesh, wouldn't you want to set the "spline mesh" mesh variables material ?

[queen dagger]

yea i thought enhanced input was just a binding to the key press

[lunar sleet]

I mean, it does. It allows you to do things when a key is pressed, which is what you’re looking for from what you’ve described

[queen dagger]

ill do that instead then

[vernal current]

Remove the index connection to setMaterial

You only have one material, material index should be 0 on all spline mesh components

[inland moon]

Hello! I'm fairly new to UE so I need help finding the right tutorial for some things. Does anyone know a tutorial that shows how to make a selectable object that moves the camera to face the puzzle and changes it to UI controls? Similar to this example

I know it's used in a lot of games, but I can't figure out the keywords to look up a tutorial for it

[eager thicket]

removed the index, thanks dawg.

I assumed by connecting the index it'd set it for each material but i guess not.

[agile moss]

Don't ask me why I am making Windows98 idk either. Small issue, whenever I click elsewhere other than a button the mouse disapears, probably because in a 3d game it is supposed to control camera rotation so it makes the mouse disapear, how do I disable this?

[forest summit]

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

I think this should work

[agile moss]

Thanks

Although it doesn't rly work

[forest summit]

sorry it's been a while since I did any UI stuff

[agile moss]

No problem

[lofty rapids]

set mouse cursor to be shown

[queen dagger]

is there a node that allows the character to be negated in hit collision?

i know there is invincibility but if a character has dot i want that to be active while they cant be targeted for another attackj

[agile moss]

Do I make that variable?
How do I use it?

[lofty rapids]

get player controller, set show mouse cursor

[agile moss]

It worked

Thanks mate

[shrewd raft]

Hi guys maybe some one know, about a Videogame or software or pluggin or blueprint that let me connect one or more virtual reality device to a PC, the PC is the server and VR are the clients?

[forest summit]

That's what I was forgetting! 😅

[agile moss]

How do I change the position of a widget when I click it

[queen dagger]

so question on the function of sequence node

i have this

it runs sequentially correct?

would a sequence node allow it to run in paralell or would it not really matter

[forest summit]

The sequence node still runs things in order

[hasty merlin]

anyone able to help me with gameplay tags and interfaces? im trying to create a tag in character bp when pause menu opens and removes it when it closes. the issue im haivng is getting the pause menus "resume" button to remove that tag and ahve the charcter bp see that. im trying to avoid casting for when i make other menus

[valid trench]

Hello, Can Someone assist me please, I am very new to unreal, What I am trying to do is, My character have health, And it decreases X every X, I want to create a actor with overlap event that restores X of health, And as soon as the character leaves that overlap collision he must start to lose health again.

[gentle urchin]

There is really no paralell in bp

[queen dagger]

gotcha

[gentle urchin]

Use a gameplaytag interface

Grant and revoke tags

[hasty merlin]

thats what im trying to do. im not certain on how to set it up. every vid ive watched on interfaces over the alst couple days leaves me more confused than the previous

[gentle urchin]

In the char you simply have a gameplaytag containee

[silent drift]

Create the healing actor and use a bool to see if the player is still inside the healing area.

On Overlap Begin set the bool to true
On Overlap exit set it to false again

And whole it's true heal.

[hasty merlin]

have that

what do i ened for the bpi?

[gentle urchin]

(Id actually do this in a component instead, as it lets younkeep everything in a single place)

[hasty merlin]

see i see a lot of vids doing taht but its for my pause menu

can i add a component to my widget?

[gentle urchin]

Where youd just do in the UI:
GetOwningPlayer->GetPawn->GetComponentOfClass[MyGameplaytagComponent]

No, but to thenpawn.

Menu just need to access it

[trim matrix]

no it doesn't

[gentle urchin]

It does

[trim matrix]

but the second can run before the first

[gentle urchin]

Untill any latent

[hasty merlin]

is this casting tho?

[gentle urchin]

Not without latent stuff going on

[trim matrix]

sure

[gentle urchin]

Dont get hung up on it

Seen from a plugin pov, using a component or an interface serves the same purpose. You've decoupled yourself from the owner

Yes, interfaces are commonly 1 to many unrelated classes , but nothing stops you from using components the same way. Pro's being that they can contain their own state, and comes supplied with whatever code and vars you put in the comp, compared to theninterface who only brings the events to the table.

But yes, this creates a hard reference between that specific component and your widget.

[forest summit]

today I learned!

[hasty merlin]

ill use components for when i start building on functionality but right now im just figuring out UI. i want to have a couple different screens

and isnt casting for every ui screen considered bad?

[gentle urchin]

Guess you wont take my word for the benefit then

[hasty merlin]

im just not understanding i tihnk

[gentle urchin]

No, if its reasonable to cast, you cast

[hasty merlin]

let me try to udnerstand casting then, why is casting deemed bad sometimes?

[gentle urchin]

You can usually safely cast to the basic player classes without much worry, As they're usually already loaded anywaus

[gentle urchin]

Casting is bad when you dont know if what you're casting to is loaded , as this creates a hard ref and forces it to be loaded regardless

Casting to MySpecificEnemyInLevel3 is bad.

Casting to MyCharacter has very little impact

[hasty merlin]

oh so if i cast to a chest and theres no chest in the area the character is in, what happens?

does it cause lag?

[gentle urchin]

It forces the chest to always stay in memory

Even if its not needed

[hasty merlin]

ahhhhhhh

[gentle urchin]

Now imagine a chain of these. You cast to chest -> chest is loaded

Chest casted to Boss -> Bossnis loaded

Boss casted to soøe enviroment prop -> this gets loaded

[trim matrix]

Cast in cpp is less laggy right

[gentle urchin]

And all of these has a bunch of assets related to them, with hardpointers, so those are also loaded.

[hasty merlin]

so ui to character causes character to stay in memory but not the ui

[gentle urchin]

That 8k texture on the bosses weapon, yupp, loaded.

[hasty merlin]

i think i understand casting then

i was fearful from word of mouth

[gentle urchin]

Also by knowing this, you can work around it

So instead of vasting to MySpecificEnemy which has textures and anims and whatnot
You instead cast to the very lightweight MyMasterEnemy

[hasty merlin]

so then i really dont need to wrory about gptags until i get to functionality and add in swords and items and magic etc

[gentle urchin]

Which strictly acts as an interface, with no direct asset references whatsoever

[supple dome]

you are mostly right but just as a tip, textures are the only exception to that, because of streaming

[hasty merlin]

and then specific enemy pulls from generic masterenemy

[trim matrix]

right? @gentle urchin

[gentle urchin]

So close 🫤

Didnt know they were an exception to it

Thought all hard ref'ed assets would be loaded

[supple dome]

textures will only load if you have "never stream" checked (automatically checked if you have a texture not power of two)

[gentle urchin]

Is child of, and can have whatever they need to have for that smashing look and killer walks

[hasty merlin]

there is a reason for calling you the second coming of the gaming lord

[gentle urchin]

Lol, im jon snow in all of this

[hasty merlin]

https://tenor.com/view/gabe-newell-gabening-intensifies-shaking-gif-15589000

[hasty merlin]

^our first lord of gaming

XD

[gentle urchin]

Ty for pointing that out 🙂 any reason one wouldnt stream non-^2 textures ?

[hasty merlin]

so then this looks right for casting and changing the var?

[gentle urchin]

I would check out the concept of encapsulation

Avoid manipulating other objects properties directly

Encapsulate the logic to be within the owning object of that property

Keeps the code clean(er)

[hasty merlin]

?

https://tenor.com/view/tiktok-dog-awkward-dog-confused-awkward-confused-dog-gif-2881577801438605193

[gentle urchin]

Thumbs on a phone..

[supple dome]

it streams via the mipmaps, 2x2, 4x4, and so on, when you got a texture non power of two, the engine wont know how to create the mipmaps

[gentle urchin]

Ah i see

[queen urchin]

Hi guys
When Im possessing a controller into character it takes controller's rotation
Is there a good way of possessing without taking this rotation?
Like, a character is already placed as I want and I down want him to turn on possess

[queen dagger]

is there a capsule component thats a box? or can i change it inheriently

[versed sun]

Box Collision

[hasty merlin]

i mean.... i woulda said the same

i saw the reaction squize and i thought you were flipping off the reply XD not pointing to it

[fathom roost]

I deleted a variable in C++, and for some reason the inheriting blueprint I have doesn't update, and still acts like the variable exists. Only after I press the Compile button on the blueprint (but not actually changing anything), will it realize that the variable doesn't exist anymore and act as expected. Does anyone know whats going on or how to fix this

the issue returns if I start the editor again

[gentle urchin]

x)

[hot lion]

Hellow there, I cannot find the proper way to cast a variable from an actor component to an animation blueprint. It seems to work, but I always got warning message about "Accessed None..."

[lofty rapids]

looks like you don't have component of that class ? the cast is likely succeeding

[old bloom]

This 5 second timeline only prints 0.0 once and never continues to update or print finished. I'm calling the function from the editor at runtime and the function is on a pawn. What's going on?

[versed sun]

I don't think timelines work with Call in Editor

but you can set the play mode to Simulate , and then it should run

[old bloom]

Thank you!

[noble ledge]

Is Capsule Trace By Channel expensive?

[trim matrix]

why would it be

[versed sun]

mine was included with ue5

[lunar sleet]

Traces are not expensive themselves but drawing debug on tick might slow you down a bit

[limber parcel]

the question is which trace is more expensive? by channel? or by object?

[lunar sleet]

Editor-only tho so doesn’t matter for game perf

[silver blade]

Heya, does anyone know what mistake might cause this? I've tried adding various IsValid's to the array, and before the branch but the error still occurs when I stop playing.

Nothing seems be be broken, my quest log widget opens fine with the child added after the quest is accepted

[noble ledge]

I am looking at a project where has a function on a timer every .1 second and it calls the capsule trace

[lunar sleet]

That’s fine. Traces are pretty cheap

[lunar sleet]

That’s the wrong code

Did you hit the magnifying glass?

[silver blade]

Yeah

Its the branch on the right

[lunar sleet]

Where’s this UIQuestLog

[trim matrix]

something is wrong --> from 1 element to an array?

[lunar sleet]

Oh that’s the widget you’re creating ?

[versed sun]

you aren't removing item from array in the loop, are you ?

[limber parcel]

whats wrong with getting an array from an actor?

[viral patio]

hey i was wondering if anyone could help me with an error i keep get. im new to unreal so i appreciate all the help

Blueprint Runtime Error: "Accessed None trying to read property Hud Widget". Node: Set Percent Graph: EventGraph Function: Execute Ubergraph BPC Player Stats Blueprint: BPC_PlayerStats

[trim matrix]

it's fine if ht gets the arrayt

I thought he was setting the array or smt

[limber parcel]

https://tenor.com/view/cat-grin-smile-smirk-awkward-gif-22382508

[trim matrix]

I'm as cpp master (i.e. a beginner in bp)

[silver blade]

So in the create widget it's creating the 'Quest Log Entry', which is the quest that's been accepted, and adds it to the section depending on the bool value
Although it doesn't seem to be getting the bool value properly because it should be getting true from the story quest bool

[limber parcel]

im the opposite xD

[lunar sleet]

Add an isvalid check inside your for each loop before plugging the target into the widget

[silver blade]

like this?

[trim matrix]

index will always be valid if you made a good system

[silver blade]

yeah unfortunately im quite new so it's not good 😓

[trim matrix]

for each loop does that part for you

wait so what is the problem?

[silver blade]

adding one like this doesn't add the widget; maybe i need to revisit how i've done things

[trim matrix]

do you change that bool somewhere?

[viral patio]

Hey i was wondering if anyone could help me with an error i keep getting. I’m new to unreal so i appreciate all the help

Blueprint Runtime Error: "Accessed None trying to read property Hud Widget". Node: Set Percent Graph: EventGraph Function: Execute Ubergraph BPC Player Stats Blueprint: BPC_PlayerStats

[trim matrix]

first I can't see
second, where is the widget variable?

[silver blade]

so i have it set up where the child BP_Quest is attached to the npc, and inside that child it stores an array including information on the quest type, description and whether it's a story quest

it doesn't get changed anywhere

[trim matrix]

then Is Story Quest will always be true so only one part of the branch will execute

[hasty merlin]

hey someone, how can i add an input to an event dispatcher?

i forget okay

leave me alone

actually dont i need a reply XD

[silver blade]

Ill create a child quest for each quest, so sometimes i'll have them set to side quests

It's just parsing through the information of the quest to see where to add it to the quest log widget

[limber parcel]

it means ure trying to access your widget when it was not created yet

[trim matrix]

dont say 'hey someone'

lol

[hasty merlin]

lel

[versed sun]

casue we can answer that its in the Details panel

[viral patio]

I swear I have though. I’ll double check. Thank as well

[hasty merlin]

i dont see the new param

wait

[versed sun]

Event Dispatcher , or Interface ?

or what is that ?

[hasty merlin]

event dispatcher. i was inside the dispatcher

thats why

its a slow day today for me

[versed sun]

got it ?

[hasty merlin]

yup gracias

[trim matrix]

wut, that was a dispatcher??? isn't that an interface

[hasty merlin]

im setting up an interactable component

[versed sun]

its if you dbl click a Event Dispatcher

[hasty merlin]

squize helped me last week make it

[trim matrix]

oh ok

[gusty dragon]

I am using the event tick to do a line trace to detect if an actor implements an interface and if it does it shows my interaction UI but I was wondering if there is a way to remove the UI after the interaction has taken place

[versed sun]

Keep track of what you detected that triggered the UI
once the line trace detects something Different , remove the UI

[gusty dragon]

but the interaction UI stays there when I am accessing a work bench for example

and like overlaps the workbench UI

[versed sun]

Remove the interactUI when you open workbench UI

[gusty dragon]

yeah I tried that but because I am using the event tick to do a line trace to detect if the actor implements an interface when I use the workbench and remove the interact UI the event tick puts it back

do u think I just scrap the event tick and use collision boxes for the interaction UI? when overlapped

[versed sun]

oh , branch your Tick part with a Bool var, when you open bench Bool=False

[gusty dragon]

omg I am such an idiot ur right

and that bool var can be used for all benches etc

ty

[noble ledge]

I am building a widget that appears when you look at items in the game that you can interact with. This widget will display a few different options like "Pickup, Use, Inspect, etc". Which would be a better way for handling the menu?

1. Create the widget and destroy the widget each time.
2. Create the widget, hide when not looking at item, update the widget options and display again when looking at new item.

[hasty merlin]

i ahve 2 cameras on my character, first person adn thrid person. if im trying to recreate this line trace, what should i select so that it works for both??

[undone bluff]

just extend the length for third person

[hasty merlin]

but how do i know which camera is active?

[trim matrix]

with a bool

[hasty merlin]

ist ehre a way to compare the 2 cameras and output goes depending on the result?

[trim matrix]

why would you compare them? everytime you switch view, a bool value changes and on that bool you can change the line trace and other thing

[hasty merlin]

this si the swap for tp to fp

[undone bluff]

well, you can get active camera from the camera manager

[hasty merlin]

camera manager?

[undone bluff]

https://dev.epicgames.com/documentation/en-us/unreal-engine/API/Runtime/Engine/Camera/APlayerCameraManager?application_version=5.3

just make a bool though

it'll make it easier to have different behaviour per perspective

[hasty merlin]

ill just add in a bool

[lunar sleet]

Not on the array itself, on the item but looks like you figured it out

[silver blade]

Yeah it still gives the error 😓 I think it's just straight up not getting the info from the array for some reason

[lunar sleet]

Maybe you have stuff in the array that’s not valid

[silver blade]

Mhm, I think I've messed up somewhere

It's probably a bit too much to ask for help with so I'll try and think on it 🙂 ty

[lunar sleet]

Drag from Array Element, isValid check, if successful, then branch

[faint pasture]

Basically the cost goes up the more stuff it has to consider, and the higher the complexity of the trace shape

Longer trace -> more expensive
Fancier geo within the collision channel -> more expensive
Capsule vs line -> more expensive

but as to whether or not it IS expensive, it depends. I regularly do over 1k per tick no problem

[lunar sleet]

Keep in mind isValid only masks the symptom so it’ll work if only some items are invalid but if the whole array has nullptrs, you’ll need to fix that too

[silver blade]

Alrighty, thanks

[lunar sleet]

Not asking in #niagara 😀

[bitter star]

I believe it's a blueprint issue but you're right, I'm going to post it in Niagara a well

[subtle ermine]

maybe some one know, about a VR Videogame or software or pluggin or blueprint that let me connect one or more virtual reality device to a PC? , the PC is the server and VR de ices are the clients

[silk bay]

Hello, the Third Player controller is C++ -is there a simple way to convert it to a blueprint? I want to add the ability to open a menu (level) hitting the esc key.

[ashen gazelle]

https://forums.unrealengine.com/t/ai-not-walking-running-animation-when-given-aimoveto/550624

I am getting this issue but none of the solutions provided fixed my issue.

[dawn gazelle]

Unreal Engine should technically be able to do that if you say, had Meta Quest devices and packaged for them, and have a server executable running on the PC.

[dawn gazelle]

Create a child of it in blueprint, and add whatever functionality you want to it, then in your game mode settings, set it to use your new blueprint player controller.

[subtle ermine]

But how? Or does there already exist a game like this today? Using that way

[dawn gazelle]

I'm sure there are hundreds of games already like this.
The "simple" how is "Create a multiplayer game in Unreal Engine and package it for Meta Quest devices, create a server executable and run it on the PC, and set up what is needed for sessions and get your devices to connect to the server".

[subtle ermine]

But please, give some names of this video games or blueprint or some reference :cc

[trim matrix]

Fortnite

[silk bay]

that worked perfectly- thank you!

[pine mesa]

I'm trying to use the Enhanced Input Mappings in my Player Blueprint but the casting to the PlayerController fails. Does anyone know why it's doing that? I already checked the level game mode and it's using the player controller.

ok this is weird now, even though it says the casting failed my input control still works on the player character... I can still move it

[dawn gazelle]

I don't do VR stuff myself, but it's no different creating a multiplayer game for VR than it is for PC, the only difference is handling how those devices interact with the game.... User interfaces need to be significantly different for VR, inputs for movement and tracking are different, and hardware specs are usually lower spec than desktop PCs. So technically, if you can create a multiplayer game in Unreal for PC, then you're already a good portion of the way to having a multiplayer VR game.

I can guarantee you there is not going to be "a blueprint", "a tutorial" or "a plugin" that will get some multiplayer VR system all working for you that you can build off of - you'll need to search for topics like "VR" with "Unreal Multiplayer w/ Sessions" and the type of VR devices you are targetting, and based on your description, using a dedicated server build and search for things based on these topics, try them out and see if they're what you're looking for and build off of those and try to combine them.

Based on your question, I'm not even sure if you've even attempted to use Unreal at all - it's not something that is going to be "easy" nor will you likely find a quick solution to what you're trying to do, and you'll likely need to find out information about lots of different things, and piece them together to get something that works how you want it to.

[viral patio]

so i set it as a variable and create it in begin play but it still doesn't work

[dawn gazelle]

Print out the "Get Controller" return value. If it's None then that means you're calling the logic before the pawn has a controller to reference.

[viral patio]

its made in event begin play. Are theses photos better?

[bold cypress]

Quick question if anyone is willing to take a shot for me. I'm setting up a simple line trace Infront of my player character to test if an enemy in Infront of them to be able to damage. I currently am checking for the parent class of my NPCS, but i also tried the direct enemy actor yet its still not working. I changed the set to do on false to ensure its working correctly and it worked fine in enabling on hitting anything. Thank you for any advice in advance

[pine mesa]

It's none. How do I fix it?

[trim matrix]

how does get owner can be the player AND the dummy?

[dawn gazelle]

The "Get Actor of Class" node attempts to return a spawned instance of an actor of the defined class. If you haven't spawned an actual "BP Mob Parent" then nothing would be returned, and it wouldn't necessarily be the exact "Hit Actor" that was detected. If you want to check the class of the actor, you can cast "Hit Actor" to "BP Mob Parent" and if the cast succeeds, then you know it's the right thing to work with.

[dawn gazelle]

Run the code you have there off of "On Possess"?

Not sure of the exact event to use that's in Pawn, but it's one of the possession ones

[bold cypress]

Ohhh, so i just need to cast the hit actor to the parent and check if from there?

[dawn gazelle]

You shouldn't need to check it - the cast itself is the check

If the cast succeeds, then the top path would execute. If the cast fails, then the hit actor isn't a BP Mob Parent or child of it.

Alternatively, you can use "Get Class" of the Hit Actor and compare that with the BP Mob Parent class (it'd be a purple pin rather than the blue pin)

[limber parcel]

if you use begin play on different actors, one might load before the other

[bold cypress]

Tried both, neither worked. Trying to fiddle around more. If i can't figure it out i'll do what i usually do. Dick around for an hour or so until an idea pops up lol

@dawn gazelle Lookin like this works Thanks mate

[dawn gazelle]

This would only be checking if the hit actor is exactly the same actor that you've stored in the "Hostile NPC" reference. Not sure if that's what you actually want.

Actually "Get Parent Actor?" I'm not even sure that's doing what you think its doing.

[bold cypress]

ayyy, it works.....

hostile npc is set as child and it works so fk it xD

spegetti code ftw

[fathom basin]

@bold cypress what are you trying to do exactly because there could be better ways to go about it

[bold cypress]

Just a simple forward check to test if its an npc or not. I'm brand new to coding so i don't know much. Hence spegetti

[dawn gazelle]

This is what the alternative is I was describing (I didn't mention the is class child of, but would be required)

[bold cypress]

ohhh, i grabbed the wrong function then. Let me go back and test

[fathom basin]

There is a simpler way: just tag the npcs with the tag NPC and make a branch with the bool actor has tag with the hit actor

[bold cypress]

I have no idea what the tag is

[dawn gazelle]

Yea tags are alright, but not necessary if using a heirarchy.

[bold cypress]

Ya, that didn't work i think maybe some of my initial creating everything coding is fked maybe?

Maybe thats why my spegetti worked and this isn't

[dawn gazelle]

Probably has something to do with your trace - it may not be hitting what you're hoping it is.

[bold cypress]

I pan my camera around for a good while to make sure

[dawn gazelle]

End result of this is that - you have a hit result, you're getting the Class of that hit result, and checking if that class is a child of BP Mob Parent.
There can only be two issues:

1. You're hitting something before your trace is actually reaching your intended target, therefore, it won't be the right thing (or nothing at all)
2. The trace is hitting the thing you're expecting but that thing doesn't inherit from BP Mob Parent.

[fathom basin]

Can you show us the code of the line trace?

[fathom basin]

Looks good but for me I sometimes need to use line trace for objects and for the object types make array and put pawn

I don’t know but it worked for me

[bold cypress]

I even tried class is child of using the spawned mob itself as the parent class and it dosn't work

[dawn gazelle]

Print out "Hit Actor" see what it is.

[bold cypress]

And with the previous code i was hitting something before you were right

I completely forgot about that AAAAANNNNNDDDDDDD turns out the hitbox is way above the mob that was the problem

No idea how that happened

[fathom basin]

Wow

[bold cypress]

<--- kinda retarded

now i just gotta figure out why tf the hitbox for it is half a mile in the sky'

Thanks guys

[trim matrix]

np

[fiery swallow]

Bro same

[bold cypress]

OHHHH the healthbar widget is coming out as the mob name while the collision box is being hit from the vertex

just gotta make the collision box smaller i guess and presto bango

huh, that wasn't it

the mesh is coming back as cube?

oh nm its not even seeing the mesh

and only seeing the hp widget as the character

[hasty merlin]

in my project i have a fpcamera and a tpcamera and im trying to setup crouch, how can i make it affect the fpcamera as well? rn its only affecting tpcamera

[lunar sleet]

Is your FP camera attached to your character’s head?

[hasty merlin]

it is yea

[lunar sleet]

Show the hierarchy

[lunar sleet]

Try putting a boom on it and attach that instead

That should hopefully move it

[hasty merlin]

whats the boom called agin?

i knwo the names not boom when adding

[undone bluff]

springarmcomponent?

[hasty merlin]

gracias

[lunar sleet]

Well in your screenshot it’s boom so I imagine it’s UE4

In UE5 it’s spring arm

[hasty merlin]

ue5.3

[lunar sleet]

So why does your screenshot show Camera Boom lol wtf

Did you migrate from UE4?

[hasty merlin]

its the default name in ue5

it auto sets the spring arm name to camera boom

idk why

did nto work tho

is there a way to se the boom arm in the playineditor?

im curious if the crouch is affecting the boom or the camera itself

[random vine]

any one knows what is spring state, or how to edit or even get it ?

[subtle ermine]

Thanks a lot! Bro

[hasty merlin]

is there a way to change which camera is gettign affected by crouching?

[random vine]

Its the capsule which is getting affected, so as well each camera below the capsule

[hasty merlin]

i have my camera attached to the mesh which is attached to the capsule, shouldnt that affect it?

[random vine]

yeah

[hasty merlin]

sadly the mesh isnt moving when i jump into fp

[random vine]

what is fp?

[hasty merlin]

first eprson

weird

i just moved it off and back on and now its fixed??????

[random vine]

so movement stops when you change to fp?

[hasty merlin]

it was

its not now

it was only for the crouch

maximum weirdness

[random vine]

the movement should still working, check if you have anyother code that affects that

[hasty merlin]

i dont. idk if it was just a bug

but once i moved the camera to just be under the capsule it fixed it

putting it back on causes no issue

[warped juniper]

Hey there. I need some help to work on my character movement...

[hasty merlin]

oh wait. its because i added in the animation now

[warped juniper]

I'm currently struggling to make the jump feel less floaty, and adding Coyote time.

[hasty merlin]

since camera is set to the head its changing it

[random vine]

which movment you mean, camera or character?

[hasty merlin]

so i made the crouch key and it was working in third person but not the first person. but the fpcamera was set to be attached to he head and because i didnt ahve the animation live yet, it wasnt moving

now i just need to remove the half height so the 3p camera doesnt move at all. know a magical value by chance?

[random vine]

crouching means to scale the capsule to a smaller half height

[hasty merlin]

i see that now. is there a way to not have the 3pcamera be affected by that?

[marble tusk]

It's just a variable you create which stores the spring's state. The function input is by ref, so it directly updates the spring state every time it's run.

[random vine]

no, either you cheat, so you add the delta location the moves the camera down, to move it up as it was never moved

[hasty merlin]

delta location? ive never heard of that

how would i go about doing that?

from what i found i need to move the camera up 30cm

[random vine]

you need to calculate that by your self

set relative location

you need to read more about that

[hasty merlin]

would it be this?

[random vine]

yeah

[hasty merlin]

what location get do i need for the boom arm?

relative location?

that was it

[random vine]

you need to make an equation based on the different variables you have by now

but let me help you with a short path

On Crouch -> set relative location: in the new location (CameraRelativeLocation + (0,0,30))

On UnCrouch -> set relative location: in the new location (CameraRelativeLocation - (0,0,30))

[random vine]

yup

[hasty merlin]

beat ya to it :p lol ty tho appreciate it

hell yea, just what my game was missing! the ability to tbag

figure i should ask this here too, how can i make it to when the prompt in the middle appears, the buttons on the right arent clickable?

ive come across a bug where i can hit resume and the middle screen prompt stays on screen

Hey... I need help to override the CanJump event on the CMC.

I just need it to have the same behaviour as it does by default, but also implement Coyote Time

An easy way would be to have the "Are you sure you want to quit" widget have an invisible background that expands to cover everything and make it hit testable, thus preventing you from clicking on anything else.

[hasty merlin]

hit testable?

how do i set that up?

[dawn gazelle]

Set the background to "visible" rather than not-hit testable in its visibility settings.

[hasty merlin]

just put a blank image there?

[dawn gazelle]

Sure

[hasty merlin]

have an image

my bad i did that backwards

does interp nodes differ between diffrenct PCes ? i gave my project to a freind to test and this exact thing with the same values run very very fast on his pc and runs slow (as i want it ) on mine this is what controls the speed the movement speed is set to .1

diferent frame rates on pc's i asume?

[round spruce]

iam using this to inc the time since movement , and yea thats what iam thinking but how do i fix it multiplying the speed with delta seconds didnt fix it

Anyone have any idea why when i print log in simulation at a frount vector the hp bar widget is logged as the actor and the mesh dosn't appear at all in log?

been stuck on this for almost 2 hours

I made a weapon that's basically a clone of the FP template pickup rifle and then placed it very far away from my player start. Copied the blueprint and the mesh setup and everything, but rebuilt from scratch. Then when I start the game, the On Component Begin Overlap event of the new weapon is casting to BP_FirstPersonCharacter even when I'm not colliding with it. What's going on here?

i think ue5 removed the delay node, so does anyone know how i can make a print string fire off every 5 seconds?
i've tried many other suggested methods but none has been better than the delay node. i am using sequence nodes in my bps btw
i want to be able to have multiple variables printed to the screen and be able to watch their values change in real-time depending on how long ive set the delay/timer

[bold cypress]

uncheck "context sensitive" on the top right when you go to place a node and it will show EVERY possible node You will get it from the search from there @ornate laurel

[ornate laurel]

thanks this seems to work. btw what if i want to use this within a function?

[gentle urchin]

Cant

Bp Functions are expected /required to instantly return

Cant have any latent nodes there. It must be om the outside(in the event graph)

[lunar sleet]

Or in a macro
